• How to configure TATA Photon+ EC1261 HUAWEI

  - by user3215

  I'm running ubuntu 10.04. I have a newly purchased TATA Photon+ Internet connection which supports Windows and Mac. On the Internet I found a article saying that it could be configured on Linux. I followed the steps to install it on Ubuntu from this link. I am still not able to get online, and need some help. Also, it is very slow, but I was told that I would see speeds up to 3.1MB. I dont have wvdial installed and cannot install it from apt as I'm not connected to internet Booting from windows I dowloaded "wvdial" .deb package and tried to install on ubuntu but it's ended with dependency problem. Automatically, don't know how, I got connected to internet only for once. Immediately I installed wvdial package after this I followed the tutorials(I could not browse and upload the files here) . From then it's showing that the device is connected in the network connections but no internet connection. Once I disable the device, it won't show as connected again and I'll have to restart my system. Sometimes the device itself not detected(wondering if there is any command to re-read the all devices). output of wvdialconf /etc/wvdial.cof: #wvdialconf /etc/wvdial.conf Editing `/etc/wvdial.conf'.

• H1 Visa interview tips–What you must know before attending the interview?

  - by Gopinath

  USA’s H1 visa allows highly qualified professionals from other countries to work in America. Many IT professionals in India aspire to go to USA on H1 and work for their clients. Recently I had a chance to study H1 visa process to help one of my friends and I would like to share what I learned. With the assumption that your H1 petition is approved and you got an interview scheduled at US Embassy for your visa stamping, here are tips you must know before attending the interview Dress Code – Formals Say no to casuals or any fancy dress when you attend the interview. It’s not a party or friends home you are visiting. Consider H1 Visa interview as your job interview and dress up in formals. There is no option B for your, you must be in formals. A plain formal shirt with a matching pant is suggested for men. Tie and Suit would not be required, but if you are a professional at management level you can consider wearing suit. Women can wear either formal Salwar or formal pant-shirt. Avoid heavy jewellery, wear what is must as per your tradition or culture. Body Language -  Smile on your face Your body language reflects what you are and what’s going on in your mind. Don’t be nervous or restless, be relaxed and wear a beautiful smile on your face. A smile is a curve that sets everything straight. When you are called for the interview, greet the interviewer with a beautiful smile. Say Good Morning/Afternoon/Evening depending on time you are visiting them. Whenever appropriate say Thank You. Generally American professionals are very friendly people and they reciprocate for your greetings. Make sure that you make them comfortable to start the interview. Carry original documents in a separate folder I don’t want to talk much about the documents that are required for your H1B interview as it’s big subject on it’s own and it requires a separate post. I assume that your consultant or employer helped you in gathering all the required documents like – petition, DS 160 forms, education & job related documents, resume, interview call letters, client letters, etc. For all the documents you are going to submit at the interview make sure that you have originals in a separate folder.  If required interviewer may ask you show the originals of any of the document you submitted for visa processing. Don’t mix the original documents with the documents you need to submit for interview. Have a separate folder for them. For those who are going to stamping along with their spouse and children, they need to carry few extra original documents like – marriage certificate, marriage photos(30 numbers)/album, birth certificates, passports, education and profession related certificates of the spouse and children. Know your role & responsibilities The interviewer will ask you questions on your roles and responsibilities at client location. Be clear what is your day to day tasks at client place and prepared to face detailed questions on the same. When asked explain clearly and also make sure what you say is inline with what is mentioned in your petition and client invitation letter. At times they may ask you questions specific to the project/technology you are going to work. So doing some homework in this area will help you easily answer the questions. Failing to answer basic questions on your role & responsibilities may result in rejection. You work for your Employer at Client location but NOT FOR CLIENT One of the important things to keep in mind that you work for your employer and you are being deputed to client location on a work visa.  Your employer is going to be solely responsible for your salary, work, promotion, pay hikes or what so ever during your stay at USA. Your client will not be responsible for anything. Lets say you are employed with Company X in India and they are applying for H1B to work at your client(ex: Microsoft) in USA, you must keep in my mind that Microsoft is not your employer. Microsoft will not pay your salaries or responsible for any employment related activities. Company X will be solely responsible for all your employer related activities. If you don’t get this correctly and say to Visa interviewer that your client is responsible, then you may get into troubles. Know your client It’s always good to know the clients with whom you are going to work in USA and their business. If your client is a well know organisation then you may not get many questions from interviewer else you need to be well prepared to provide details like – nature of business, location, size of the organisation, etc.  Get to know the basic details about your client and be confident while providing those details to the interviewer. Also make sure that you never talk about any confidential details of your client projects and business. Revealing confidential details of your client may land your job itself in soup. Make sure that your spouse is also in sync with you If you’ve applied a H4 visa for your spouse along with your H1, make sure that spouse is in sync with you. Your spouse also should know the basic details of your job, your employer, client and location where you will be travelling. Your spouse should also be prepared to answers questions related to marriage, their profession(if working), kids, education, etc. Interviewers will try to asses your spouse communication skills, whereabouts while staying in USA and would they prefer to work USA or not. On H4, which is a dependent visa, your spouse is not allowed to work in USA and at any point your spouse should not show the intentions to search for work in USA. Less luggage more comfort You would have definitely heard that there are lot of restrictions on what you can carry along with you to an US Embassy while attending the interview. To be frank it’s not good to say there are many restrictions, but there are a hell a lot of restrictions. There are unbelievable restrictions and it’s for the safety of everyone. You are not allowed to carry mobile phones, CD/DVDs, USBs, bank cards, cameras, cosmetics, food(except baby food), water, wallets, backpacks, sealed covers, etc. Trust me most of the things we carry with us regularly every day are not allowed inside. As there are 100s of restrictions, it would be easier if you understand what you can carry along with you and just carry them alone. Ask your employer/consultant to provide you a checklist of items that you can carry. Most what you would require are H1B related documents provided by the employer/consultant Photographs All original documents supporting your H1B Passports Some cash for your travel expenses (avoid coins) Any important phone number / details written in a paper(like your cab driver number, etc.) If you carry restricted stuff then you will be stopped at security checks, you have to find people who can safely keep all the restricted items. Due to heavy restrictions in and around the US Embassy you will not find any  place to keep your luggage. So just carry the bare minimum things required so that you feel more comfortable.

• Refactoring Part 1 : Intuitive Investments

  - by Wes McClure

  Fear, it’s what turns maintaining applications into a nightmare.  Technology moves on, teams move on, someone is left to operate the application, what was green is now perceived brown.  Eventually the business will evolve and changes will need to be made.  The approach to those changes often dictates the long term viability of the application.  Fear of change, lack of passion and a lack of interest in understanding the domain often leads to a paranoia to do anything that doesn’t involve duct tape and bailing twine.  Don’t get me wrong, those have a place in the short term viability of a project but they don’t have a place in the long term.  Add to it “us versus them” in regards to the original team and those that maintain it, internal politics and other factors and you have a recipe for disaster.  This results in code that quickly becomes unmanageable.  Even the most clever of designs will eventually become sub optimal and debt will amount that exponentially makes changes difficult.  This is where refactoring comes in, and it’s something I’m very passionate about.  Refactoring is about improving the process whereby we make change, it’s an exponential investment in the process of change. Without it we will incur exponential complexity that halts productivity. Investments, especially in the long term, require intuition and reflection.  How can we tackle new development effectively via evolving the original design and paying off debt that has been incurred? The longer we wait to ask and answer this question, the more it will cost us.  Small requests don’t warrant big changes, but realizing when changes now will pay off in the long term, and especially in the short term, is valuable. I have done my fair share of maintaining applications and continuously refactoring as needed, but recently I’ve begun work on a project that hasn’t had much debt, if any, paid down in years.  This is the first in a series of blog posts to try to capture the process which is largely driven by intuition of smaller refactorings from other projects. Signs that refactoring could help: Testability How can decreasing test time not pay dividends? One of the first things I found was that a very important piece often takes 30+ minutes to test.  I can only imagine how much time this has cost historically, but more importantly the time it might cost in the coming weeks: I estimate at least 10-20 hours per person!  This is simply unacceptable for almost any situation.  As it turns out, about 6 hours of working with this part of the application and I was able to cut the time down to under 30 seconds!  In less than the lost time of one week, I was able to fix the problem for all future weeks! If we can’t test fast then we can’t change fast, nor with confidence. Code is used by end users and it’s also used by developers, consider your own needs in terms of the code base.  Adding logic to enable/disable features during testing can help decouple parts of an application and lead to massive improvements.  What exactly is so wrong about test code in real code?  Often, these become features for operators and sometimes end users.  If you cannot run an integration test within a test runner in your IDE, it’s time to refactor. Readability Are variables named meaningfully via a ubiquitous language? Is the code segmented functionally or behaviorally so as to minimize the complexity of any one area? Are aspects properly segmented to avoid confusion (security, logging, transactions, translations, dependency management etc) Is the code declarative (what) or imperative (how)?  What matters, not how.  LINQ is a great abstraction of the what, not how, of collection manipulation.  The Reactive framework is a great example of the what, not how, of managing streams of data. Are constants abstracted and named, or are they just inline? Do people constantly bitch about the code/design? If the code is hard to understand, it will be hard to change with confidence.  It’s a large undertaking if the original designers didn’t pay much attention to readability and as such will never be done to “completion.”  Make sure not to go over board, instead use this as you change an application, not in lieu of changes (like with testability). Complexity Simplicity will never be achieved, it’s highly subjective.  That said, a lot of code can be significantly simplified, tidy it up as you go.  Refactoring will often converge upon a simplification step after enough time, keep an eye out for this. Understandability In the process of changing code, one often gains a better understanding of it.  Refactoring code is a good way to learn how it works.  However, it’s usually best in combination with other reasons, in effect killing two birds with one stone.  Often this is done when readability is poor, in which case understandability is usually poor as well.  In the large undertaking we are making with this legacy application, we will be replacing it.  Therefore, understanding all of its features is important and this refactoring technique will come in very handy. Unused code How can deleting things not help? This is a freebie in refactoring, it’s very easy to detect with modern tools, especially in statically typed languages.  We have VCS for a reason, if in doubt, delete it out (ok that was cheesy)! If you don’t know where to start when refactoring, this is an excellent starting point! Duplication Do not pray and sacrifice to the anti-duplication gods, there are excellent examples where consolidated code is a horrible idea, usually with divergent domains.  That said, mediocre developers live by copy/paste.  Other times features converge and aren’t combined.  Tools for finding similar code are great in the example of copy/paste problems.  Knowledge of the domain helps identify convergent concepts that often lead to convergent solutions and will give intuition for where to look for conceptual repetition. 80/20 and the Boy Scouts It’s often said that 80% of the time 20% of the application is used most.  These tend to be the parts that are changed.  There are also parts of the code where 80% of the time is spent changing 20% (probably for all the refactoring smells above).  I focus on these areas any time I make a change and follow the philosophy of the Boy Scout in cleaning up more than I messed up.  If I spend 2 hours changing an application, in the 20%, I’ll always spend at least 15 minutes cleaning it or nearby areas. This gives a huge productivity edge on developers that don’t. Ironically after a short period of time the 20% shrinks enough that we don’t have to spend 80% of our time there and can move on to other areas.   Refactoring is highly subjective, never attempt to refactor to completion!  Learn to be comfortable with leaving one part of the application in a better state than others.  It’s an evolution, not a revolution.  These are some simple areas to look into when making changes and can help get one started in the process.  I’ve often found that refactoring is a convergent process towards simplicity that sometimes spans a few hours but often can lead to massive simplifications over the timespan of weeks and months of regular development.

• Not attending the LUGM mini-meetup - 05. Oct 2013

  Not attending a meeting of the LUGM can be fun, too. It's getting a bit of a habit that Ish is organising small gatherings, aka mini-meetups, of the Linux User Group Mauritius/Meta (LUGM) almost every Saturday. There they mainly discuss and talk about various elements of using Linux as ones main operating systems and the possibilities you are going to have. On top of course, some tips & tricks about mastering the command line and initial steps in scripting or even writing HTML. In general, sounds like a good portion of fun and great spirit of community. Unfortunately, I'm usually quite busy with private and family matters during the weekend and so I already signalised that I wouldn't be around. Well, at least not physically... But this Saturday a couple of things worked out faster than expected and so I was hanging out on my machine. I made virtual contact with one of Pawan's messages over on Facebook... And somehow that kicked off some kind of an online game fun on basic configuration of Apache HTTPd 2.2.x, PHP 5.x and how to improve the overall performance of a newly installed blog based on WordPress. Default configuration files Nitin's website finally came alive and despite the dark theme and the hidden Apple 'fanboy' advertisement I was more interested in the technical situation. As with any new installation there is usually quite some adjustment to be done. And Nitin's page was no exception. Unfortunately, out of the box installations of Apache httpd and PHP are too verbose and expose too much information under the hood. You might think that this isn't really a problem at all, well, think about it again after completely reading this article. First, I checked the HTTP response headers - using either Chrome Developer Tools or Firefox Web Developer extension - of Nitin's page and based on that I advised him to lower the noise levels a little bit. It's not really necessary that detailed information about web server software and scripting language has to be published in every response made. Quite a number of script kiddies and exploits actually check for version specifics prior to an attack. So, removing at least version details hardens the system a little bit. In particular, I'm talking about these response values: Server X-Powered-By How to achieve that? By tweaking the configuration files... Namely, we are going to look into the following ones: apache2.conf httpd.conf .htaccess php.ini The above list contains some additional files, I'm talking about in the next paragraphs. Anyway, those are the ones involved. Tweaking Apache Open your favourite text editor and start to modify the apache2.conf. Eventually, you might like to have a quick peak at the file to see whether it is necessary to adjust it or not. Following is a handy combination of commands to get an overview of your active directives: # sudo grep -v '#' /etc/apache2/apache2.conf | grep -v '^$' | less There you keep an eye on those two Apache directives: ServerSignature Off ServerTokens Prod If that's not the case, change them as highlighted above. In order to activate your modifications you have to restart Apache httpd server. On Debian and Ubuntu you might use apache2ctl for that, on other distributions you might have to use service or run the init-scripts again: # sudo apache2ctl configtestSyntax OK# sudo apache2ctl restart Refresh your website and check the HTTP response header. Tweaking PHP5 (a little bit) Next, check your php.ini file with the following statement: # sudo grep -v ';' /etc/php5/apache2/php.ini | grep -v '^$' | less And check the value of expose_php = Off Again, if it's not as highlighted, change it... Some more Apache love Okay, back to Apache it might also be interesting to improve the situation about browser caching and removing more obsolete information. When you run your website against the usual performance checks like Google Page Speed and Yahoo YSlow you might see those check points with bad grades on a standard, default configuration. Well, this can be done easily. Configure entity tags (ETags) ETags are only interesting when you run your websites on a farm of multiple web servers. Removing this data for your static resources is very simple in Apache. As we are going to deal with the HTTP response header information you have to ensure that Apache is capable to manipulate them. First, check your enabled modules: # sudo ls -al /etc/apache2/mods-enabled/ | grep headers And in case that the 'headers' module is not listed, you have to enable it from the available ones: # sudo a2enmod headers Second, check your httpd.conf file (in case it exists): # sudo grep -v '#' /etc/apache2/httpd.conf | grep -v '^$' | less In newer (better said fresh) installations you might have to create a new configuration file below your conf.d folder with your favourite text editor like so: # sudo nano /etc/apache2/conf.d/headers.conf Then, in order to tweak your HTTP responses either check for those lines or add them: Header unset ETagFileETag None In case that your file doesn't exist or those lines are missing, feel free to create/add them. Afterwards, check your Apache configuration syntax and restart your running instances as already shown above: # sudo apache2ctl configtestSyntax OK# sudo apache2ctl restart Add Expires headers To improve the loading performance of your website, you should take some care into the proper configuration of how to leverage the browser's ability to cache certain resources and files. This is done by adding an Expires: value to the HTTP response header. Generally speaking it is advised that you specify a near-future, read: 1 week or a little bit more, for your static content like JavaScript files or Cascading Style Sheets. One solution to adjust this is to put some instructions into the .htaccess file in the root folder of your web site. Of course, this could also be placed into a more generic location of your Apache installation but honestly, I'd like to keep this at the web site level. Following some adjustments I'm currently using on this blog site: # Turn on Expires and set default to 0ExpiresActive OnExpiresDefault A0 # Set up caching on media files for 1 year (forever?)<FilesMatch "\.(flv|ico|pdf|avi|mov|ppt|doc|mp3|wmv|wav)$">ExpiresDefault A29030400Header append Cache-Control "public"</FilesMatch> # Set up caching on media files for 1 week<FilesMatch "\.(js|css)$">ExpiresDefault A604800Header append Cache-Control "public"</FilesMatch> # Set up caching on media files for 31 days<FilesMatch "\.(gif|jpg|jpeg|png|swf)$">ExpiresDefault A2678400Header append Cache-Control "public"</FilesMatch> As we are editing the .htaccess files, it is not necessary to restart Apache. In case that your web site doesn't load anymore or you're experiencing an error while trying to restart your httpd, check that the 'expires' module is actually an enabled module: # ls -al /etc/apache2/mods-enabled/ | grep expires# sudo a2enmod expires Of course, the instructions above a re not feature complete but I hope that they might provide a better default configuration for your LAMP stack. Resume of the day Within a couple of hours, and while being occupied with an eLearning course on SQL Server 2012, I had some good fun in helping and assisting other LUGM members while they were some kilometers away at Bagatelle. According to other blog articles it seems that Nitin had quite some moments of desperation. Just for the records: At no time it was my intention to either kick his butt or pull a leg on him. Simply, providing some input based on the lessons I've learned over the last couple of years configuring Apache HTTPd and PHP. Check out the other blogs, too: LUGM mini-meetup... Epic! Superb Saturday Linux Meetup And last but not least, the man himself: The end of a new beginning Cheers, and happy community'ing! Updates Due to our weekly Code & Coffee sessions in the MSCC community, I had a chance to talk to Nitin directly and he showed me the problems directly on his machine. This led to update this article hence the paragraphs on enabling the modules 'headers' and 'expires'.

• Exalogic 2.0.1 Tea Break Snippets - Creating a ModifyJeOS VirtualBox

  - by The Old Toxophilist

  Following on from my previous blog entry "Modifying the Base Template" I decided to put together a quick blog to show how to create a small VirtualBox, guest, that can be used to execute the ModifyJeOS and hence edit you templates. One of the main advantages of this is that Templates can be created away from the Exalogic Environment. For the Guest OS I chose OEL 6u3 and decided to create it as a basic server because I did not require a graphical interface but it's a simple change to create it with a GUI. Required Software Virtual Box. Oracle Enterprise Linux. Creating the VM I'll assume that the reader is experienced with Virtual Box and installing OEL and hence will make this section brief. Create VirtualBox Guest Create a new VirtualBox Guest and select oracle Linux 64 bit. Follow through the create process and select Dynamic Disk Size and the default 12GB disk size. The actual image will be a lot smaller than this but the OEL install will fail with insufficient disk space if you attempt a smaller size. Once the guest has been created attach the previously downloaded OEL 6u3 iso to the cd drive and start the guest. Install OEL On starting the guest the system will boot off the associated OEL 6u3 iso and take you through the standard installation process. Select all the appropriate information but when you reach the installation type select Basic Server because we do not need that additional packages and only need to access through the command line interface. Complete the installation and reboot the Guest. At this point we now have a basic OEL server running. Installing Guest Add-ons Before we can easily access the Guest we will need to add the VirtualBox guest add-ons. These will provide better keyboard and mouse integration and allow access the shared folders on the host machine. Before we can do this we will need to do the following: Enable Networking. Install additional rpms.  To enable the networking (eth0), that appears to be disabled by default, we can execute: ifup eth0 This will start the eth0 connection but once the Guest is rebooted the network will be down again. To resolve this you will need to edit the /etc/sysconfig/network-scripts/ifcfg-eth0 file and change the ONBOOT parameter to "yes". Now we have enabled the network we will need to install a number of addition rpm. First we will need to configure the yum repository as follows: [ol6_latest] name=Oracle Linux $releasever Latest ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/latest/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1 [ol6_ga_base] name=Oracle Linux $releasever GA installation media copy ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/0/base/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=0 [ol6_u1_base] name=Oracle Linux $releasever Update 1 installation media copy ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/1/base/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=0 [ol6_u2_base] name=Oracle Linux $releasever Update 2 installation media copy ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/2/base/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=0 [ol6_u3_base] name=Oracle Linux $releasever Update 3 installation media copy ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/3/base/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=0 [ol6_UEK_latest] name=Latest Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEK/latest/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1 [ol6_UEK_base] name=Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEK/base/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=0 Once the repository has been edited we will need to execute the following yum commands: yum update yum install gcc yum install kernel-uek-devel yum install kernel-devel yum install createrepo At this point we now have all the additional packages required to install the VirtualBox Guest Add-ons. So select Devices->InstallGuest Additions on you running guest: This will simply place the VirtualBoxGuestAdditions.iso in the virtual cd and we will need to execute the following before we can run them. mkdir /media/cdrom mount -t iso9660 -o ro /dev/cdrom /media/cdrom cd /media/cdrom/ ls ./VBoxLinuxAdditions.run This will initiate the install and kernel rebuild. What you will notice is that during the installation a Failed will be displayed but this is simply because we have no graphical components. At this point we the installation will also have added the vboxsf group to the system and to access any shared folders we will create our user will need to be a member of this group an so the next stage is to add the root user to this group as follows: usermod -G vboxsf root cat /etc/group cat /etc/passwd init 0 Now simply shutdown the guest and add the Shared folder within your guests settings. Install ModifyJeOS Once the shared folder has been added restart the guest and change directory into the shared folder (/media/sf_<folder name>). For the next step I am assuming the ModifyJeOS rpms are located in the shared folder. We can simply execute: rpm -ivh ovm-modify-jeos-1.1.0-17.el5.noarch.rpm # Test with modifyjeos Using ModifyJeOS I have a modified MountSystemImg.sh script that should be copied into the /root/bin directory (you may need to create this) and from here it can be executed from any location: MountSystemImg.sh #!/bin/sh # The script assumes it's being run from the directory containing the System.img # Export for later i.e. during unmount export LOOP=`losetup -f` export SYSTEMIMG=/mnt/elsystem export TEMPLATEDIR=`pwd` # Make Temp Mount Directory mkdir -p $SYSTEMIMG # Create Loop for the System Image losetup $LOOP System.img kpartx -a $LOOP mount /dev/mapper/`basename $LOOP`p2 $SYSTEMIMG #Change Dir into mounted Image cd $SYSTEMIMG echo "######################################################################" echo "### ###" echo "### Starting Bash shell for editing. When completed log out to ###" echo "### Unmount the System.img file. ###" echo "### ###" echo "######################################################################" echo bash cd ~ cd $TEMPLATEDIR umount $SYSTEMIMG kpartx -d $LOOP losetup -d $LOOP rm -rf $SYSTEMIMG This script will simple create a mount directory, mount the System.img and then start a new shell in the mounted directory. On exiting the shell it will unmount the System.img. It only requires that you execute the script in the directory containing the System.img. These can be created under the mounted shared directory. In the example below I have extracted the Base template within the shared folder and then renamed it OEL_40GB_ROOT before changing into that directory and executing the script.

• Attaching a Command to the WP7 Application Bar.

  - by mbcrump

  One of the biggest problems that I’ve seen with people creating WP7 applications is how do you bind the application bar to a Relay Command. If your using MVVM then this is particular important. Let’s examine the code that one might add to start with.  <phone:PhoneApplicationPage.ApplicationBar> <shell:ApplicationBar IsVisible="True" IsMenuEnabled="True"> <shell:ApplicationBarIconButton x:Name="appbar_button1" IconUri="/icons/appbar.questionmark.rest.png" Text="About"> <i:Interaction.Triggers> <i:EventTrigger EventName="Click"> <GalaSoft_MvvmLight_Command:EventToCommand Command="{Binding DisplayAbout, Mode=OneWay}" /> </i:EventTrigger> </i:Interaction.Triggers> </shell:ApplicationBarIconButton> <shell:ApplicationBar.MenuItems> <shell:ApplicationBarMenuItem x:Name="menuItem1" Text="MenuItem 1"></shell:ApplicationBarMenuItem> <shell:ApplicationBarMenuItem x:Name="menuItem2" Text="MenuItem 2"></shell:ApplicationBarMenuItem> </shell:ApplicationBar.MenuItems> </shell:ApplicationBar> </phone:PhoneApplicationPage.ApplicationBar> Everything looks right. But we quickly notice that we have a squiggly line under our Interaction.Triggers. The problem is that the object is not a FrameworkObject. This same code would have worked perfect if this were a normal button. OK. Point has been proved. Let’s make the ApplicationBar support Commands. So, go ahead and create a new project using MVVM Light. If you want to check out the source and work along side this tutorial then click here.  7 Easy Steps to have binding on the Application Bar using MVVM Light (I might add that you don’t have to use MVVM Light to get this functionality, I just prefer it.) 1) Download MVVM Light if you don’t already have it and install the project templates. It is available at http://mvvmlight.codeplex.com/. 2) Click File-New Project and navigate to Silverlight for Windows Phone. Make sure you use the MVVM Light (WP7) Template. 3) Now that we have our project setup and ready to go let’s download a wrapper created by Nicolas Humann here, it is called Phone7.Fx. After you download it then extract it somewhere that you can find it. This wrapper will make our application bar/menu item bindable. 4) Right click References inside your WP7 project and add the .dll file to your project. 5) In your MainPage.xaml you will need to add the proper namespace to it. Don’t forget to build your project afterwards. xmlns:Preview="clr-namespace:Phone7.Fx.Preview;assembly=Phone7.Fx.Preview" 6) Now you can add the BindableAppBar to your MainPage.xaml with a few lines of code.  <Preview:BindableApplicationBar x:Name="AppBar" BarOpacity="1.0" > <Preview:BindableApplicationBarIconButton Command="{Binding DisplayAbout}" IconUri="/icons/appbar.questionmark.rest.png" Text="About" /> <Preview:BindableApplicationBar.MenuItems> <Preview:BindableApplicationBarMenuItem Text="Settings" Command="{Binding InputBox}" /> </Preview:BindableApplicationBar.MenuItems> </Preview:BindableApplicationBar> So your final MainPage.xaml will look similar to this: NOTE: The AppBar will be located inside of the Grid using this wrapper.   <!--LayoutRoot contains the root grid where all other page content is placed--> <Grid x:Name="LayoutRoot" Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <!--TitlePanel contains the name of the application and page title--> <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="24,24,0,12"> <TextBlock x:Name="ApplicationTitle" Text="{Binding ApplicationTitle}" Style="{StaticResource PhoneTextNormalStyle}" /> <TextBlock x:Name="PageTitle" Text="{Binding PageName}" Margin="-3,-8,0,0" Style="{StaticResource PhoneTextTitle1Style}" /> </StackPanel> <!--ContentPanel - place additional content here--> <Grid x:Name="ContentGrid" Grid.Row="1"> <TextBlock Text="{Binding Welcome}" Style="{StaticResource PhoneTextNormalStyle}" HorizontalAlignment="Center" VerticalAlignment="Center" FontSize="40" /> </Grid> <Preview:BindableApplicationBar x:Name="AppBar" BarOpacity="1.0" > <Preview:BindableApplicationBarIconButton Command="{Binding DisplayAbout}" IconUri="/icons/appbar.questionmark.rest.png" Text="About" /> <Preview:BindableApplicationBar.MenuItems> <Preview:BindableApplicationBarMenuItem Text="Settings" Command="{Binding InputBox}" /> </Preview:BindableApplicationBar.MenuItems> </Preview:BindableApplicationBar> </Grid> 7) Let’s go ahead and create the RelayCommands and write them up to a MessageBox by editing our MainViewModel.cs file. public class MainViewModel : ViewModelBase { public string ApplicationTitle { get { return "MVVM LIGHT"; } } public string PageName { get { return "My page:"; } } public string Welcome { get { return "Welcome to MVVM Light"; } } public RelayCommand DisplayAbout { get; private set; } public RelayCommand InputBox { get; private set; } /// <summary> /// Initializes a new instance of the MainViewModel class. /// </summary> public MainViewModel() { if (IsInDesignMode) { // Code runs in Blend --> create design time data. } else { DisplayAbout = new RelayCommand(() => { MessageBox.Show("About box called!"); }); InputBox = new RelayCommand(() => { MessageBox.Show("settings button called"); }); } } If you run the project now you should get something similar to this (notice the AppBar at the bottom):  Now if you hit the question mark then you will get the following MessageBox: The MenuItem works as well so for Settings: As you can see, its pretty easy to add a Command to the ApplicationBar/MenuItem.

• Visual Studio 2010 Productivity Tips and Tricks&ndash;Part 1: Extensions

  - by ToStringTheory

  I don’t know about you, but when it comes to development, I prefer my environment to be as free of clutter as possible.  It may surprise you to know that I have tried ReSharper, and did not like it, for the reason that I stated above.  In my opinion, it had too much clutter.  Don’t get me wrong, there were a couple of features that I did like about it (inversion of if blocks, code feedback), but for the most part, I actually felt that it was slowing me down. Introduction Another large factor besides intrusiveness/speed in my choice to dislike ReSharper would probably be that I have become comfortable with my current setup and extensions.  I believe I have a good collection, and am quite happy with what I can accomplish in a short amount of time.  I figured that I would share some of my tips/findings regarding Visual Studio productivity here, and see what you had to say. The first section of things that I would like to cover, are Visual Studio Extensions.  In case you have been living under a rock for the past several years, Extensions are available under the Tools menu in Visual Studio: The extension manager enables integrated access to the Microsoft Visual Studio Gallery online with access to a few thousand different extensions.  I have tried many extensions, but for reasons of lack reliability, usability, or features, have uninstalled almost all of them.  However, I have come across several that I find I can not do without anymore: NuGet Package Manager (Microsoft) Perspectives (Adam Driscoll) Productivity Power Tools (Microsoft) Web Essentials (Mads Kristensen) Extensions NuGet Package Manager To be honest, I debated on whether or not to put this in here.  Most people seem to have it, however, there was a time when I didn’t, and was always confused when blogs/posts would say to right click and “Add Package Reference…” which with one of the latest updates is now “Manage NuGet Packages”.  So, if you haven’t downloaded the NuGet Package Manager yet, or don’t know what it is, I would highly suggest downloading it now! Features Simply put, the NuGet Package Manager gives you a GUI and command line to access different libraries that have been uploaded to NuGet. Some of its features include: Ability to search NuGet for packages via the GUI, with information in the detail bar on the right. Quick access to see what packages are in a solution, and what packages have updates available, with easy 1-click updating. If you download a package that requires references to work on other NuGet packages, they will be downloaded and referenced automatically. Productivity Tip If you use any type of source control in Visual Studio as well as using NuGet packages, be sure to right-click on the solution and click "Enable NuGet Package Restore". What this does is add a NuGet package to the solution so that it will be checked in along side your solution, as well as automatically grab packages from NuGet on build if needed. This is an extremely simple system to use to manage your package references, instead of having to manually go into TFS and add the Packages folder. Perspectives I can't stand developing with just one monitor. Especially if it comes to debugging. The great thing about Visual Studio 2010, is that all of the panels and windows are floatable, and can dock to other screens. The only bad thing is, I don't use the same toolset with everything that I am doing. By this, I mean that I don't use all of the same windows for debugging a web application, as I do for coding a WPF application. Only thing is, Visual Studio doesn't save the screen positions for all of the undocked windows. So, I got curious one day and decided to check and see if there was an extension to help out. This is where I found Perspectives. Features Perspectives gives you the ability to configure window positions across any or your monitors, and then to save the positions in a profile. Perspectives offers a Panel to manage different presets/favorites, and a toolbar to add to the toolbars at the top of Visual Studio. Ability to 'Favorite' a profile to add it to the perspectives toolbar. Productivity Tip Take the time to setup profiles for each of your scenarios - debugging web/winforms/xaml, coding, maintenance, etc. Try to remember to use the profiles for a few days, and at the end of a week, you may find that your productivity was never better. Productivity Power Tools Ah, the Productivity Power Tools... Quite possibly one of my most used extensions, if not my most used. The tool pack gives you a variety of enhancements ranging from key shortcuts, interface tweaks, and completely new features to Visual Studio 2010. Features I don't want to bore you with all of the features here, so here are my favorite: Quick Find - Unobtrusive search box in upper-right corner of the code window. Great for searching in general, especially in a file. Solution Navigator - The 'Solution Explorer' on steroids. Easy to search for files, see defined members/properties/methods in files, and my favorite feature is the 'set as root' option. Updated 'Add Reference...' Dialog - This is probably my favorite enhancement period... The 'Add Reference...' dialog redone in a manner that resembles the Extension/Package managers. I especially love the ability to search through all of the references. "Ctrl - Click" for Definition - I am still getting used to this as I usually try to use my keyboard for everything, but I love the ability to hold Ctrl and turn property/methods/variables into hyperlinks, that you click on to see their definitions. Great for travelling down a rabbit hole in an application to research problems. While there are other commands/utilities, I find these to be the ones that I lean on the most for the usefulness. Web Essentials If you have do any type of web development in ASP .Net, ASP .Net MVC, even HTML, I highly suggest grabbing the Web Essentials right NOW! This extension alone is great for productivity in web development, and greatly decreases my development time on new features. Features Some of its best features include: CSS Previews - I say 'previews' because of the multiple kinds of previews in CSS that you get font-family, color, background/background-image previews. This is great for just tweaking UI slightly in different ways and seeing how they look in the CSS window at a glance. Live Preview - One word - awesome! This goes well with my multi-monitor setup. I put the site on one monitor in a Live Preview panel, and then as I make changes to CSS/cshtml/aspx/html, the preview window will update with each save/build automatically. For CSS, you can even turn on live-update, so as you are tweaking CSS, the style changes in real time. Great for tweaking colors or font-sizes. Outlining - Small, but I like to be able to collapse regions/declarations that are in the way of new work, or are just distracting. Commenting Shortcuts - I don't know why it wasn't included by default, but it is nice to have the key shortcuts for commenting working in the CSS editor as well. Productivity Tip When working on a site, hit CTRL-ALT-ENTER to launch the Live Preview window. Dock it to another monitor. When you make changes to the document/css, just save and glance at the other monitor. No need to alt tab, then alt tab before continuing editing. Conclusion These extensions are only the most useful and least intrusive - ones that I use every day. The great thing about Visual Studio 2010 is the extensibility options that it gives developers to utilize. Have an extension that you use that isn't intrusive, but isn't listed here? Please, feel free to comment. I love trying new things, and am always looking for new additions to my toolset of the most useful. Finally, please keep an eye out for Part 2 on key shortcuts in Visual Studio. Also, if you are visiting my site (http://tostringtheory.com || http://geekswithblogs.net/tostringtheory) from an actual browser and not a feed, please let me know what you think of the new styling!

• Augmenting your Social Efforts via Data as a Service (DaaS)

  - by Mike Stiles

  The following is the 3rd in a series of posts on the value of leveraging social data across your enterprise by Oracle VP Product Development Don Springer and Oracle Cloud Data and Insight Service Sr. Director Product Management Niraj Deo. In this post, we will discuss the approach and value of integrating additional “public” data via a cloud-based Data-as-as-Service platform (or DaaS) to augment your Socially Enabled Big Data Analytics and CX Management. Let’s assume you have a functional Social-CRM platform in place. You are now successfully and continuously listening and learning from your customers and key constituents in Social Media, you are identifying relevant posts and following up with direct engagement where warranted (both 1:1, 1:community, 1:all), and you are starting to integrate signals for communication into your appropriate Customer Experience (CX) Management systems as well as insights for analysis in your business intelligence application. What is the next step? Augmenting Social Data with other Public Data for More Advanced Analytics When we say advanced analytics, we are talking about understanding causality and correlation from a wide variety, volume and velocity of data to Key Performance Indicators (KPI) to achieve and optimize business value. And in some cases, to predict future performance to make appropriate course corrections and change the outcome to your advantage while you can. The data to acquire, process and analyze this is very nuanced: It can vary across structured, semi-structured, and unstructured data It can span across content, profile, and communities of profiles data It is increasingly public, curated and user generated The key is not just getting the data, but making it value-added data and using it to help discover the insights to connect to and improve your KPIs. As we spend time working with our larger customers on advanced analytics, we have seen a need arise for more business applications to have the ability to ingest and use “quality” curated, social, transactional reference data and corresponding insights. The challenge for the enterprise has been getting this data inline into an easily accessible system and providing the contextual integration of the underlying data enriched with insights to be exported into the enterprise’s business applications. The following diagram shows the requirements for this next generation data and insights service or (DaaS): Some quick points on these requirements: Public Data, which in this context is about Common Business Entities, such as - Customers, Suppliers, Partners, Competitors (all are organizations) Contacts, Consumers, Employees (all are people) Products, Brands This data can be broadly categorized incrementally as - Base Utility data (address, industry classification) Public Master Reference data (trade style, hierarchy) Social/Web data (News, Feeds, Graph) Transactional Data generated by enterprise process, workflows etc. This Data has traits of high-volume, variety, velocity etc., and the technology needed to efficiently integrate this data for your needs includes - Change management of Public Reference Data across all categories Applied Big Data to extract statics as well as real-time insights Knowledge Diagnostics and Data Mining As you consider how to deploy this solution, many of our customers will be using an online “cloud” service that provides quality data and insights uniformly to all their necessary applications. In addition, they are requesting a service that is: Agile and Easy to Use: Applications integrated with the service can obtain data on-demand, quickly and simply Cost-effective: Pre-integrated into applications so customers don’t have to Has High Data Quality: Single point access to reference data for data quality and linkages to transactional, curated and social data Supports Data Governance: Becomes more manageable and cost-effective since control of data privacy and compliance can be enforced in a centralized place Data-as-a-Service (DaaS) Just as the cloud has transformed and now offers a better path for how an enterprise manages its IT from their infrastructure, platform, and software (IaaS, PaaS, and SaaS), the next step is data (DaaS). Over the last 3 years, we have seen the market begin to offer a cloud-based data service and gain initial traction. On one side of the DaaS continuum, we see an “appliance” type of service that provides a single, reliable source of accurate business data plus social information about accounts, leads, contacts, etc. On the other side of the continuum we see more of an online market “exchange” approach where ISVs and Data Publishers can publish and sell premium datasets within the exchange, with the exchange providing a rich set of web interfaces to improve the ease of data integration. Why the difference? It depends on the provider’s philosophy on how fast the rate of commoditization of certain data types will occur. How do you decide the best approach? Our perspective, as shown in the diagram below, is that the enterprise should develop an elastic schema to support multi-domain applicability. This allows the enterprise to take the most flexible approach to harness the speed and breadth of public data to achieve value. The key tenet of the proposed approach is that an enterprise carefully federates common utility, master reference data end points, mobility considerations and content processing, so that they are pervasively available. One way you may already be familiar with this approach is in how you do Address Verification treatments for accounts, contacts etc. If you design and revise this service in such a way that it is also easily available to social analytic needs, you could extend this to launch geo-location based social use cases (marketing, sales etc.). Our fundamental belief is that value-added data achieved through enrichment with specialized algorithms, as well as applying business “know-how” to weight-factor KPIs based on innovative combinations across an ever-increasing variety, volume and velocity of data, will be where real value is achieved. Essentially, Data-as-a-Service becomes a single entry point for the ever-increasing richness and volume of public data, with enrichment and combined capabilities to extract and integrate the right data from the right sources with the right factoring at the right time for faster decision-making and action within your core business applications. As more data becomes available (and in many cases commoditized), this value-added data processing approach will provide you with ongoing competitive advantage. Let’s look at a quick example of creating a master reference relationship that could be used as an input for a variety of your already existing business applications. In phase 1, a simple master relationship is achieved between a company (e.g. General Motors) and a variety of car brands’ social insights. The reference data allows for easy sort, export and integration into a set of CRM use cases for analytics, sales and marketing CRM. In phase 2, as you create more data relationships (e.g. competitors, contacts, other brands) to have broader and deeper references (social profiles, social meta-data) for more use cases across CRM, HCM, SRM, etc. This is just the tip of the iceberg, as the amount of master reference relationships is constrained only by your imagination and the availability of quality curated data you have to work with. DaaS is just now emerging onto the marketplace as the next step in cloud transformation. For some of you, this may be the first you have heard about it.

• Looking into the JQuery Overlays Plugin

  - by nikolaosk

  I have been using JQuery for a couple of years now and it has helped me to solve many problems on the client side of web development.  You can find all my posts about JQuery in this link. In this post I will be providing you with a hands-on example on the JQuery Overlays Plugin.If you want you can have a look at this post, where I describe the JQuery Cycle Plugin.You can find another post of mine talking about the JQuery Carousel Lite Plugin here. Another post of mine regarding the JQuery Image Zoom Plugin can be found here.I will be writing more posts regarding the most commonly used JQuery Plugins. With the JQuery Overlays Plugin we can provide the user (overlay) with more information about an image when the user hovers over the image. I have been using extensively this plugin in my websites. In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like. You can use Visual Studio 2012 Express edition. You can download it here.  You can download this plugin from this link. I launch Expression Web 4.0 and then I type the following HTML markup (I am using HTML 5) <html lang="en"> <head>    <link rel="stylesheet" href="ImageOverlay.css" type="text/css" media="screen" />    <script type="text/javascript" src="jquery-1.8.3.min.js"></script>    <script type="text/javascript" src="jquery.ImageOverlay.min.js"></script>         <script type="text/javascript">        $(function () {            $("#Liverpool").ImageOverlay();        });    </script>   </head><body>    <ul id="Liverpool" class="image-overlay">        <li>            <a href="www.liverpoolfc.com">                <img alt="Liverpool" src="championsofeurope.jpg" />                <div class="caption">                    <h3>Liverpool Football club</h3>                    <p>The greatest club in the world</p>                </div>            </a>        </li>    </ul></body></html> This is a very simple markup. I have added references to the JQuery library (current version is 1.8.3) and the JQuery Overlays Plugin. Then I add 1 image in the element with "id=Liverpool". There is a caption class as well, where I place the text I want to show when the mouse hovers over the image. The caption class and the Liverpool id element are styled in the ImageOverlay.css file that can also be downloaded with the plugin.You can style the various elements of the html markup in the .css file. The Javascript code that makes it all happen follows.   <script type="text/javascript">        $(function () {            $("#Liverpool").ImageOverlay();        });    </script>        I am just calling the ImageOverlay function for the Liverpool ID element.The contents of ImageOverlay.css file follow .image-overlay { list-style: none; text-align: left; }.image-overlay li { display: inline; }.image-overlay a:link, .image-overlay a:visited, .image-overlay a:hover, .image-overlay a:active { text-decoration: none; }.image-overlay a:link img, .image-overlay a:visited img, .image-overlay a:hover img, .image-overlay a:active img { border: none; }.image-overlay a{    margin: 9px;    float: left;    background: #fff;    border: solid 2px;    overflow: hidden;    position: relative;}.image-overlay img{    position: absolute;    top: 0;    left: 0;    border: 0;}.image-overlay .caption{    float: left;    position: absolute;    background-color: #000;    width: 100%;    cursor: pointer;    /* The way to change overlay opacity is the follow properties. Opacity is a tricky issue due to        longtime IE abuse of it, so opacity is not offically supported - use at your own risk.         To play it safe, disable overlay opacity in IE. */    /* For Firefox/Opera/Safari/Chrome */    opacity: .8;    /* For IE 5-7 */    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=80);    /* For IE 8 */    -MS-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=80)";}.image-overlay .caption h1, .image-overlay .caption h2, .image-overlay .caption h3,.image-overlay .caption h4, .image-overlay .caption h5, .image-overlay .caption h6{    margin: 10px 0 10px 2px;    font-size: 26px;    font-weight: bold;    padding: 0 0 0 5px;    color:#92171a;}.image-overlay p{    text-indent: 0;    margin: 10px;    font-size: 1.2em;} It couldn't be any simpler than that. I view my simple page in Internet Explorer 10 and it works as expected. I have tested this simple solution in all major browsers and it works fine.Have a look at the picture below. You can test it yourself and see the results in your favorite browser. Hope it helps!!!

• 5 Lessons learnt in localization / multi language support in WPF

  - by MarkPearl

  For the last few months I have been secretly working away at the second version of an application that we initially released a few years ago. It’s called MaxCut and it is a free panel/cut optimizer for the woodwork, glass and metal industry. One of the motivations for writing MaxCut was to get an end to end experience in developing an application for general consumption. From the early days of v1 of MaxCut I would get the odd email thanking me for the software and then listing a few suggestions on how to improve it. Two of the most dominant suggestions that we received were… Support for imperial measurements (the original program only supported the metric system) Multi language support (we had someone who volunteered to translate the program into Japanese for us). I am not going to dive into the Imperial to Metric support in todays blog post, but I would like to cover a few brief lessons we learned in adding support for multi-language functionality in the software. I have sectioned them below under different lessons. Lesson 1 – Build multi-language support in from the start So the first lesson I learnt was if you know you are going to do multi language support – build it in from the very beginning! One of the power points of WPF/Silverlight is data binding in XAML and so while it wasn’t to painful to retro fit multi language support into the programing, it was still time consuming and a bit tedious to go through mounds and mounds of views and would have been a minor job to have implemented this while the form was being designed. Lesson 2 – Accommodate for varying word lengths using Grids The next lesson was a little harder to learn and was learnt a bit further down the road in the development cycle. We developed everything in English, assuming that other languages would have similar character length words for equivalent meanings… don’t!. A word that is short in your language may be of varying character lengths in other languages. Some language like Dutch and German allow for concatenation of nouns which has the potential to create really long words. We picked up a few places where our views had been structured incorrectly so that if a word was to long it would get clipped off or cut out. To get around this we began using the WPF grid extensively with column widths that would automatically expand if they needed to. Generally speaking the grid replacement got round this hurdle, and if in future you have a choice between a stack panel or a grid – think twice before going for the easier option… often the grid will be a bit more work to setup, but will be more flexible. Lesson 3 – Separate the separators Our initial run through moving the words to a resource dictionary led us to make what I thought was one potential mistake. If we had a label like the following… “length : “ In the resource dictionary we put it as a single entry. This is fine until you start using a word more than once. For instance in our scenario we used the word “length’ frequently. with different variations of the word with grammar and separators included in the resource we ended up having what I would consider a bloated dictionary. When we removed the separators from the words and put them as their own resources we saw a dramatic reduction in dictionary size… so something that looked like this… “length : “ “length. “ “length?” Was reduced to… “length” “:” “?” “.” While this may not seem like a reduction at first glance, consider that the separators “:?.” are used everywhere and suddenly you see a real reduction in bloat. Lesson 4 – Centralize the Language Dictionary This lesson was learnt at the very end of the project after we had already had a release candidate out in the wild. Because our translations would be done on a volunteer basis and remotely, we wanted it to be really simple for someone to translate our program into another language. As a common design practice we had tiered the application so that we had a business logic layer, a ui layer, etc. The problem was in several of these layers we had resource files specific for that layer. What this resulted in was us having multiple resource files that we would need to send to our translators. To add to our problems, some of the wordings were duplicated in different resource files, which would result in additional frustration from our translators as they felt they were duplicating work. Eventually the workaround was to make a separate project in VS2010 with just the language translations. We then exposed the dictionary as public within this project and made it as a reference to the other projects within the solution. This solved out problem as now we had a central dictionary and could remove any duplication's. Lesson 5 – Make a dummy translation file to test that you haven’t missed anything The final lesson learnt about multi language support in WPF was when checking if you had forgotten to translate anything in the inline code, make a test resource file with dummy data. Ideally you want the data for each word to be identical. In our instance we made one which had all the resource key values pointing to a value of test. This allowed us point the language file to our test resource file and very quickly browse through the program and see if we had missed any linking. The alternative to this approach is to have two language files and swap between the two while running the program to make sure that you haven’t missed anything, but the downside of dual language file approach is that it is much a lot harder spotting a mistake if everything is different – almost like playing Where’s Wally / Waldo. It is much easier spotting variance in uniformity – meaning when you put the “test’ keyword for everything, anything that didn’t say “test” stuck out like a sore thumb. So these are my top five lessons learnt on implementing multi language support in WPF. Feel free to make any suggestions in the comments section if you feel maybe something is more important than one of these or if I got it wrong!

• Lambda&rsquo;s for .NET made easy&hellip;

  - by mbcrump

  The purpose of my blog is to explain things for a beginner to intermediate c# programmer. I’ve seen several blog post that use lambda expressions always assuming the audience is familiar with them. The purpose of this post is to make them simple and easily understood. Let’s begin with a definition. A lambda expression is an anonymous function that can contain expressions and statements, and can be used to create delegates or expression tree types. So anonymous function… delegates or expression tree types? I don’t get it??? Confused yet?   Lets break this into a few definitions and jump right into the code. anonymous function – is an "inline" statement or expression that can be used wherever a delegate type is expected. delegate - is a type that references a method. Once a delegate is assigned a method, it behaves exactly like that method. The delegate method can be used like any other method, with parameters and a return value. Expression trees - represent code in a tree-like data structure, where each node is an expression, for example, a method call or a binary operation such as x < y.   Don’t worry if this still sounds confusing, lets jump right into the code with a simple 3 line program. We are going to use a Function Delegate (all you need to remember is that this delegate returns a value.) Lambda expressions are used most commonly with the Func and Action delegates, so you will see an example of both of these. Lambda Expression 3 lines. using System; using System.Collections.Generic; using System.Linq; using System.Text;   namespace ConsoleApplication7 {     class Program     {          static void Main(string[] args)         {             Func<int, int> myfunc = x => x *x;             Console.WriteLine(myfunc(6).ToString());             Console.ReadLine();         }       } } Is equivalent to Old way of doing it. using System; using System.Collections.Generic; using System.Linq; using System.Text;   namespace ConsoleApplication7 {     class Program     {          static void Main(string[] args)         {               Console.WriteLine(myFunc(6).ToString());             Console.ReadLine();         }            static int myFunc(int x)          {              return x * x;            }       } } In the example, there is a single parameter, x, and the expression is x*x. I’m going to stop here to make sure you are still with me. A lambda expression is an unnamed method written in place of a delegate instance. In other words, the compiler converts the lambda expression to either a : A delegate instance An expression tree All lambda have the following form: (parameters) => expression or statement block Now look back to the ones we have created. It should start to sink in. Don’t get stuck on the => form, use it as an identifier of a lambda. A Lamba expression can also be written in the following form: Lambda Expression. using System; using System.Collections.Generic; using System.Linq; using System.Text;   namespace ConsoleApplication7 {     class Program     {          static void Main(string[] args)         {             Func<int, int> myFunc = x =>             {                 return x * x;             };               Console.WriteLine(myFunc(6).ToString());             Console.ReadLine();         }       } } This form may be easier to read but consumes more space. Lets try an Action delegate – this delegate does not return a value. Action Delegate example. using System; using System.Collections.Generic; using System.Linq; using System.Text;   namespace ConsoleApplication7 {     class Program     {          static void Main(string[] args)         {             Action<string> myAction = (string x) => { Console.WriteLine(x); };             myAction("michael has made this so easy");                                   Console.ReadLine();         }       } } Lambdas can also capture outer variables (such as the example below) A lambda expression can reference the local variables and parameters of the method in which it’s defined. Outer variables referenced by a lambda expression are called captured variables. Capturing Outer Variables using System; using System.Collections.Generic; using System.Linq; using System.Text;   namespace ConsoleApplication7 {     class Program     {          static void Main(string[] args)         {             string mike = "Michael";             Action<string> myAction = (string x) => {                 Console.WriteLine("{0}{1}", mike, x);          };             myAction(" has made this so easy");                                   Console.ReadLine();         }       } } Lamba’s can also with a strongly typed list to loop through a collection.   Used w a strongly typed list. using System; using System.Collections.Generic; using System.Linq; using System.Text;   namespace ConsoleApplication7 {     class Program     {          static void Main(string[] args)         {             List<string> list = new List<string>() { "1", "2", "3", "4" };             list.ForEach(s => Console.WriteLine(s));             Console.ReadLine();         }       } } Outputs: 1 2 3 4 I think this will get you started with Lambda’s, as always consult the MSDN documentation for more information. Still confused? Hopefully you are not.

• Loaded OBJ Model Will Not Display in OpenGL / C++ Project

  - by Drake Summers

  I have been experimenting with new effects in game development. The programs I have written have been using generic shapes for the visuals. I wanted to test the effects on something a bit more complex, and wrote a resource loader for Wavefront OBJ files. I started with a simple cube in blender, exported it to an OBJ file with just vertices and triangulated faces, and used it to test the resource loader. I could not get the mesh to show up in my application. The loader never gave me any errors, so I wrote a snippet to loop through my vertex and index arrays that were returned from the loader. The data is exactly the way it is supposed to be. So I simplified the OBJ file by editing it directly to just show a front facing square. Still, nothing is displayed in the application. And don't worry, I did check to make sure that I decreased the value of each index by one while importing the OBJ. - BEGIN EDIT I also tested using glDrawArrays(GL_TRIANGLES, 0, 3 ); to draw the first triangle and it worked! So the issue could be in the binding of the VBO/IBO items.

I attempted to provide everything of relevance and omit what may have been unnecessary. I'm hoping this isn't some really poor mistake, because I have been at this for a few days now. If anyone has any suggestions or advice on the matter, I look forward to hearing it. As a final note: I added some arrays into the code with manually entered data, and was able to display meshes by using those arrays instead of the generated ones. I do not understand!

• Getting Started With Tailoring Business Processes

  - by Richard Bingham

  In this article, and for the sake of simplicity, we will use the term “On-Premise” to mean a deployment where you have design-time development access to the instance, including administration of the technology components, the applications filesystem, and the database. In reality this might be a local development instance that is then supported by a team who can deploy your customizations to the restricted production instance equivalents. Tools Overview Firstly let’s look at the Design-Time tools within JDeveloper for customizing and extending the artifacts of a Business Process. In essence this falls into two buckets; SOA Composite Editor for working with BPEL processes, and the BPM Studio. The SOA Composite Editor As a standard extension to JDeveloper, this graphical design tool should be familiar to anyone previously worked with Oracle SOA Server. With easy-to-use modeling capability, backed-up by full XML source-view (for read-only), it provides everything that is needed to implement the technical design. In simple terms, once deployed to the remote SOA Server the composite components (like Mediator) leverage the Event Delivery Network (EDN) for interaction with the application logic. If you are customizing an existing Fusion Applications BPEL process then be aware that it does support MDS-based customization layers just like Page Composer where different customizations are used based on the run-time context, like for a specific Product or Business Unit. This also makes them safe from patching and upgrades, although only a single active version of the composite is available at run-time. This is defined by a field on the composite record, available in Enterprise Manager. Obviously if you wish to fire different activities and tasks based on the user context then you can should include switches to fork the flows in your custom BPEL process. Figure 1 – A BPEL process in Composite Editor The following describes the simplified steps for making customizations to BPEL processes. This is the most common method of changing the business processes of Fusion Applications, as over 400 BPEL-based composite applications are provided out-of-the-box. Setup your local Fusion Applications JDeveloper environment. The SOA Composite Editor should be installed as part of the Fusion Applications extension. If there are problems you can also find it under the ‘Check for Updates’ help menu option. Since SOA Server is not part of the JDeveloper integrated WebLogic Server, setup a standalone WebLogic environment for deploying and testing. Obviously you might use a Fusion Applications development instance also. Package the existing standard Fusion Applications SOA Composite using Enterprise Manager and export it as a complete SOA Archive (SAR) file, resulting in a local .jar file. You may need to ask your system administrator for this. Import the exported SAR .jar file into JDeveloper using the File menu, under the option ‘SOA Archive into SOA Project’. In JDeveloper set the appropriate customization layer values, and then change from the default role to the Fusion Applications Customization Developer role. Make the customizations and save the application project. Finally redeploy the composite application, either to a direct Application Server connection, or as a fresh SAR (jar) file that can then be re-imported and deployed via Enterprise Manager. The Business Process Management (BPM) Suite In addition to the relatively low-level development environment associated with BPEL process creation, Oracle provides a suite of products that allow business process adjustments to be made without the need for some of the programming skills.  The aim is to abstract much of the technical implementation and to provide a Business Analyst tools for immediately implementing organization changes. Obviously there are some limitations on what they can do, however the BPM Suite functionality increases with each release and for the majority of the cases the tools remains as applicable as its developer-orientated sister. At the current time business processes must be explicitly coded to support just one of these use-cases, either BPEL for developer use or BPM for business analyst use. That said, they both run on the same SOA Server in much the same way. The components bundled in each SOA Composite Application can be verified by inspection through Enterprise Manager. Figure 2 – A BPM Process in JDeveloper BPM Suite. BPM processes are written in a standard notation (BPMN) and the modeling tools are very similar to that of BPEL. The steps to deploy a custom BPM process are also essentially much the same, since the BPM process is bundled into a SOA Composite just like a BPEL process. As such the SOA Composite Editor  actually has support for both artifacts and even allows use of them together, such as a calling a BPM process as a partnerlink from a BPEL process. For more details see the references below. Business Analyst Tooling In addition to using JDeveloper extensions for BPM development, there are run-time tools that Business Analysts can use to make adjustments, so that without high costs of an IT project the system can be tuned to match changes to the business operation. The first tool to consider is the BPM Composer, deployed with the middleware SOA Server and accessible online, and for Fusion Applications it is under the Business Process icon on the homepage of the Application Composer. Figure 3 – Business Process Composer showing a CRM process flow. The key difference between this and using JDeveloper is that the BPM Composer has a Business Catalog prepopulated with features and functions that can be used, mostly through registered WebServices. This means no coding or complex interface development is required, simply drag-drop-configure. The items in the business catalog are seeded by either Oracle (as a BPM Template) or added to by your own custom development. You cannot create or generate catalog content from BPM Composer directly. As per the screenshot you can see the Business Catalog content in the BPM Project browser region. In addition, other online tools for use by Business Analysts include the BPM Worklist application for editing business rules and approval management configuration, plus the SOA Composer which focuses on non-approval business rules and domain value maps. At the current time there are only a handful of BPM processes shipped with Fusion Applications HCM and CRM, including on-boarding workers and processing customer registrations.  This also means a limited number of associated BPM Templates provided out-of-the-box, therefore a limited Business Catalog. That said, BPM-based extension is a powerful capability to leverage and will most likely develop going forwards, especially for use in SaaS deployments where full design-time JDeveloper access is not available.

• Nokia Windows Phone 8 App Collection

  - by Tim Murphy

  I recently upgraded to a Nokia Lumia 920.  Along with it came the availability of a number of Nokia developed apps or apps that Nokia has made available from other developers.  Below is a summary of some of the ones that I have used to this point.  There are quite a few of them so I won’t be covering everything that is available. Nokia Maps I am quite pleased with the accuracy of Nokia Maps and not having to tap the screen for each turn any more.  The information on the screen is quite good as well.  The couple of improvements I would like to see are for the voice directions to include which street or exit you need to use and improve the search accuracy.  Bing maps had much better search results in my opinion. Nokia Drive This one really had me confused when I first setup the phone.  I was driving down the road and suddenly I am getting notification tones, but there were no visual notifications on the phone.  It seems that in their infinite wisdom Nokia thinks I don’t know when I am going over the speed limit and need to be told. ESPN I really liked my ESPN app on Windows Phone 7.5, but I am not getting the type of experience I was looking for out of this app.  While it allows me to pick my favorite teams, but there isn’t a pivot page or panorama page that shows a summary of my favorite teams.  I have also found that the live tile don’t update very often.  Over all I am rather disappointed compared app produced by ESPN. Smart Shoot I really need to get the kids to let me use this on.  I like the concept, but I need to spend more time with it.  The idea how running the camera through a continuous shooting mode and then picking the best is something that I have done with my DSLR and am glad to see it available here. Cinemagraph Here is a fun filter.  It doesn’t have the most accurate editing features, but it is fun to stop certain parts of a scene and let other parts move.  As a test I stopped the traffic on the highway and let the traffic on the frontage road flow.  It makes for a fun effect.  If nothing else it could be great for sending prank animations to your friends. YouSendIt I have only briefly touched this application.  What I don’t understand is why it is needed.  Most of the functionality seems to be similar to SkyDrive and it gives you less storage.  They only feature that seems to differentiate the app is the signature capability. Creative Studio This app has some nice quick edits, but it is not very comprehensive.  I am also not to thrilled with the user experience.  It puts you though an initial color cast series that I’m not sure why it is there.  Discovery of the remaining adjustments isn’t that great.  In the end I found myself wanting Thumbia back. Panorama This is one of the apps that I like.  I found it easy to use as it guides you with a target circle that you center for it to take the next pictures.  It also stitches the images with amazing speed.  The one thing I wish it had was the capability to turn the phone into portrait orientation and do a taller panorama.  Perhaps we will see this in the future. Nokia Music After getting over the missing album art I found that there were a number of missing features with this app as well.  I have a Zune HD and I am used to being able to go through my collection and adding songs, albums or artists to my now playing.  There also doesn’t seem to be a way to manage playlists that I have seen yet.  Other than that the UI is familiar and it give Nokia City Lens Augmented reality is a cool concept, but I still haven’t seen it implemented in a compelling fashion beyond a demo at TED a couple of years ago.  The app still leaves me wanting as well.  It does give an interesting toy.  It gives you the ability to look for general categories and see general direction and clusters of locations.  I think as this concept is better thought out it will become more compelling. Nokia Trailers I don’t know how often I will use this app, but I do like being able to see what movies are being promoted.  I can’t wait for The Hobbit to come out and the trailer was just what the doctor ordered.  I can see coming back to this app from time to time. PhotoBeamer PhotoBeamer is a strange beast that needs a better instruction manual.  It seems a lot like magic but very confusing.  I need some more testing, but I don’t think this is something that most people are going to understand quickly and may give up before getting it to work.  I may put an update here after playing with it further. Ringtone Maker The app was just published and it didn’t work very well for me. It couldn’t find 95% of the songs that Nokia Music was playing for me and crashed several times.  It also had songs named wrong that when I checked them in Nokia Music they were fine.  This app looks like it has a long way to go. Summary In all I think that Nokia is offering a well rounded set of initial applications that can get any new owner started.  There is definitely room for improvement in all of these apps.  The main need is usability upgrades.  I would guess that with feedback from users they will come up to acceptable levels.  Try them out and see if you agree. del.icio.us Tags: Windows Phone,Nokia,Lumia,Nokia Apps,ESPN,PhotoBeamer,City Lens,YouSendIt,Drive,Maps

• Restructuring a large Chrome Extension/WebApp

  - by A.M.K

  I have a very complex Chrome Extension that has gotten too large to maintain in its current format. I'd like to restructure it, but I'm 15 and this is the first webapp or extension of it's type I've built so I have no idea how to do it. TL;DR: I have a large/complex webapp I'd like to restructure and I don't know how to do it. Should I follow my current restructure plan (below)? Does that sound like a good starting point, or is there a different approach that I'm missing? Should I not do any of the things I listed? While it isn't relevant to the question, the actual code is on Github and the extension is on the webstore. The basic structure is as follows: index.html <html> <head> <link href="css/style.css" rel="stylesheet" /> <!-- This holds the main app styles --> <link href="css/widgets.css" rel="stylesheet" /> <!-- And this one holds widget styles --> </head> <body class="unloaded"> <!-- Low-level base elements are "hardcoded" here, the unloaded class is used for transitions and is removed on load. i.e: --> <div class="tab-container" tabindex="-1"> <!-- Tab nav --> </div> <!-- Templates for all parts of the application and widgets are stored as elements here. I plan on changing these to <script> elements during the restructure since <template>'s need valid HTML. --> <template id="template.toolbar"> <!-- Template content --> </template> <!-- Templates end --> <!-- Plugins --> <script type="text/javascript" src="js/plugins.js"></script> <!-- This contains the code for all widgets, I plan on moving this online and downloading as necessary soon. --> <script type="text/javascript" src="js/widgets.js"></script> <!-- This contains the main application JS. --> <script type="text/javascript" src="js/script.js"></script> </body> </html> widgets.js (initLog || (window.initLog = [])).push([new Date().getTime(), "A log is kept during page load so performance can be analyzed and errors pinpointed"]); // Widgets are stored in an object and extended (with jQuery, but I'll probably switch to underscore if using Backbone) as necessary var Widgets = { 1: { // Widget ID, this is set here so widgets can be retreived by ID id: 1, // Widget ID again, this is used after the widget object is duplicated and detached size: 3, // Default size, medium in this case order: 1, // Order shown in "store" name: "Weather", // Widget name interval: 300000, // Refresh interval nicename: "weather", // HTML and JS safe widget name sizes: ["tiny", "small", "medium"], // Available widget sizes desc: "Short widget description", settings: [ { // Widget setting specifications stored as an array of objects. These are used to dynamically generate widget setting popups. type: "list", nicename: "location", label: "Location(s)", placeholder: "Enter a location and press Enter" } ], config: { // Widget settings as stored in the tabs object (see script.js for storage information) size: "medium", location: ["San Francisco, CA"] }, data: {}, // Cached widget data stored locally, this lets it work offline customFunc: function(cb) {}, // Widgets can optionally define custom functions in any part of their object refresh: function() {}, // This fetches data from the web and caches it locally in data, then calls render. It gets called after the page is loaded for faster loads render: function() {} // This renders the widget only using information from data, it's called on page load. } }; script.js (initLog || (window.initLog = [])).push([new Date().getTime(), "These are also at the end of every file"]); // Plugins, extends and globals go here. i.e. Number.prototype.pad = .... var iChrome = function(refresh) { // The main iChrome init, called with refresh when refreshing to not re-run libs iChrome.Status.log("Starting page generation"); // From now on iChrome.Status.log is defined, it's used in place of the initLog iChrome.CSS(); // Dynamically generate CSS based on settings iChrome.Tabs(); // This takes the tabs stored in the storage (see fetching below) and renders all columns and widgets as necessary iChrome.Status.log("Tabs rendered"); // These will be omitted further along in this excerpt, but they're used everywhere // Checks for justInstalled => show getting started are run here /* The main init runs the bare minimum required to display the page, this sets all non-visible or instantly need things (such as widget dragging) on a timeout */ iChrome.deferredTimeout = setTimeout(function() { iChrome.deferred(refresh); // Pass refresh along, see above }, 200); }; iChrome.deferred = function(refresh) {}; // This calls modules one after the next in the appropriate order to finish rendering the page iChrome.Search = function() {}; // Modules have a base init function and are camel-cased and capitalized iChrome.Search.submit = function(val) {}; // Methods within modules are camel-cased and not capitalized /* Extension storage is async and fetched at the beginning of plugins.js, it's then stored in a variable that iChrome.Storage processes. The fetcher checks to see if processStorage is defined, if it is it gets called, otherwise settings are left in iChromeConfig */ var processStorage = function() { iChrome.Storage(function() { iChrome.Templates(); // Templates are read from their elements and held in a cache iChrome(); // Init is called }); }; if (typeof iChromeConfig == "object") { processStorage(); } Objectives of the restructure Memory usage: Chrome apparently has a memory leak in extensions, they're trying to fix it but memory still keeps on getting increased every time the page is loaded. The app also uses a lot on its own. Code readability: At this point I can't follow what's being called in the code. While rewriting the code I plan on properly commenting everything. Module interdependence: Right now modules call each other a lot, AFAIK that's not good at all since any change you make to one module could affect countless others. Fault tolerance: There's very little fault tolerance or error handling right now. If a widget is causing the rest of the page to stop rendering the user should at least be able to remove it. Speed is currently not an issue and I'd like to keep it that way. How I think I should do it The restructure should be done using Backbone.js and events that call modules (i.e. on storage.loaded = init). Modules should each go in their own file, I'm thinking there should be a set of core files that all modules can rely on and call directly and everything else should be event based. Widget structure should be kept largely the same, but maybe they should also be split into their own files. AFAIK you can't load all templates in a folder, therefore they need to stay inline. Grunt should be used to merge all modules, plugins and widgets into one file. Templates should also all be precompiled. Question: Should I follow my current restructure plan? Does that sound like a good starting point, or is there a different approach that I'm missing? Should I not do any of the things I listed? Do applications written with Backbone tend to be more intensive (memory and speed) than ones written in Vanilla JS? Also, can I expect to improve this with a proper restructure or is my current code about as good as can be expected?

• Silverlight Recruiting Application Part 6 - Adding an Interview Scheduling Module/View

  Between the last post and this one I went ahead and carried the ideas for the Jobs module and view into the Applicants module and view- they're both doing more or less the same thing, except with different objects being at their core.  Made for an easy cut-and-paste operation with a few items being switched from one to another.  Now that we have the ability to add postings and applicants, wouldn't it be nice if we could schedule an interview?  Of course it would! Scheduling Module I think you get the drift from previous posts that these project structures start looking somewhat similar.  The interview scheduling module is no different than the rest- it gets a SchedulingModule.cs file at the root that inherits from IModule, and there is a single SchedulerView.xsml and SchedulerViewModel.cs setup for our V+VM.  We have one unique concern as we enter into this- RadScheduler deals with AppointmentsSource, not ItemsSource, so there are some special considerations to take into account when planning this module. First, I need something which inherits from AppointmentBase.  This is the core of the RadScheduler appointment, and if you are planning to do any form of custom appointment, you'll want it to inherit from this.  Then you can add-on functionality as needed.  Here is my addition to the mix, the InterviewAppointment: 01.public class InterviewAppointment : AppointmentBase 02.{ 03.    private int _applicantID; 04.    public int ApplicantID 05.    { 06.        get { return this._applicantID; } 07.        set 08.        { 09.            if (_applicantID != value) 10.            { 11.                _applicantID = value; 12.                OnPropertyChanged("ApplicantID"); 13.            } 14.        } 15.    } 16.   17.    private int _postingID; 18.    public int PostingID 19.    { 20.        get { return _postingID; } 21.        set 22.        { 23.            if (_postingID != value) 24.            { 25.                _postingID = value; 26.                OnPropertyChanged("PostingID"); 27.            } 28.        } 29.    } 30.   31.    private string _body; 32.    public string Body 33.    { 34.        get { return _body; } 35.        set 36.        { 37.            if (_body != value) 38.            { 39.                _body = value; 40.                OnPropertyChanged("Body"); 41.            } 42.        } 43.    } 44.   45.    private int _interviewID; 46.    public int InterviewID 47.    { 48.        get { return _interviewID; } 49.        set 50.        { 51.            if (_interviewID != value) 52.            { 53.                _interviewID = value; 54.                OnPropertyChanged("InterviewID"); 55.            } 56.        } 57.    } 58.   59.    public override IAppointment Copy() 60.    { 61.        IAppointment appointment = new InterviewAppointment(); 62.        appointment.CopyFrom(this);             63.        return appointment; 64.    } 65.   66.    public override void CopyFrom(IAppointment other) 67.    {             68.        base.CopyFrom(other); 69.        var appointment = other as InterviewAppointment; 70.        if (appointment != null) 71.        { 72.            ApplicantID = appointment.ApplicantID; 73.            PostingID = appointment.PostingID; 74.            Body = appointment.Body; 75.            InterviewID = appointment.InterviewID; 76.        } 77.    } 78.} Nothing too exciting going on here, we just make sure that our custom fields are persisted (specifically set in CopyFrom at the bottom) and notifications are fired- otherwise this ends up exactly like the standard appointment as far as interactions, etc.  But if we've got custom appointment items... that also means we need to customize what our appointment dialog window will look like. Customizing the Edit Appointment Dialog This initially sounds a lot more intimidating than it really is.  The first step here depends on what you're dealing with for theming, but for ease of everything I went ahead and extracted my templates in Blend for RadScheduler so I could modify it as I pleased.  For the faint of heart, the RadScheduler template is a few thousand lines of goodness since there are some very complex things going on in that control.  I've gone ahead and trimmed down the template parts I don't need as much as possible, so what is left is all that is relevant to the Edit Appointment Dialog.  Here's the resulting Xaml, with line numbers, so I can explain further: 001.<UserControl.Resources> 002.    <!-- begin Necessary Windows 7 Theme Resources for EditAppointmentTemplate --> 003.    <helpers:DataContextProxy x:Key="DataContextProxy" /> 004.       005.    <telerik:Windows7Theme x:Key="Theme" /> 006.    <SolidColorBrush

Where we start getting into the dialog in question is line 132, but line 407 is where things start getting interesting.  The ItemsSource is pointing at a list that exists in my ViewModel (or code-behind, if it is used as a DataContext), the SelectedValue is the item I am actually binding from the applicant (note the TwoWay binding), and SelectedValuePath and DisplayMemberPath ensure the proper applicant is being displayed from the collection.  You will also see similar starting on line 420 where I do the same for the Jobs we'll be displaying. Just to wrap-up the Xaml, here's the RadScheduler declaraction that ties this all together and will be the main focus of our view: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.                  Grid.Row="1" 03.                  Grid.Column="1" 04.                  Width="800" 05.                  MinWidth="600" 06.                  Height="500" 07.                  MinHeight="300" 08.                  AppointmentsSource="{Binding Interviews}" 09.                  EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 10.                  command:AppointmentAddedEventClass.Command="{Binding AddAppointmentCommand}" 11.                  command:ApptCreatedEventClass.Command="{Binding ApptCreatingCommand}" 12.                  command:ApptEditedEventClass.Command="{Binding ApptEditedCommand}" 13.                  command:ApptDeletedEventClass.Command="{Binding ApptDeletedCommand}"> 14.</telerikScheduler:RadScheduler> Now, we get to the ViewModel and what it takes to get that rigged up.  And for those of you who remember the jobs post, those command:s in the Xaml are pointing to attached behavior commands that reproduce the respective events.  This becomes very handy when we're setting up the code-behind version. ;) ViewModel I've been liking this approach so far, so I'm going to put the entire ViewModel here and then go into the lines of interest.  Of course, feel free to ask me questions about anything that isn't clear (by line number, ideally) so I can help out if I have missed anything important: 001.public class SchedulerViewModel : ViewModelBase 002.{ 003.    private readonly IEventAggregator eventAggregator;

4.    base.ExecuteCommand(); 5.} And the ViewModel is none the wiser, the appointments just work as far as it is concerned since as they are created they become InterviewAppointments.  End result?  I've customized my EditAppointmentDialog as follows: And adding, editing, and deleting appointments works like a charm.  I can even 'edit' by moving appointments around RadScheduler, so as they are dropped into a timeslot they perform their full edit routine and things get updated. And then, the Code-Behind Version Perhaps the thing I like the most about doing one then the other is I get to steal 90% or more of the code from the MVVM version.  For example, the only real changes to the Code-Behind Xaml file exist in the control declaration, in which I use events instead of attached-behavior-event-commands: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.                  Grid.Row="1" 03.                  Grid.Column="1" 04.                  Width="800" 05.                  MinWidth="600" 06.                  Height="500" 07.                  MinHeight="300" 08.                  EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 09.                  AppointmentAdded="xJobsScheduler_AppointmentAdded" 10.                  AppointmentCreating="xJobsScheduler_AppointmentCreating" 11.                  AppointmentEdited="xJobsScheduler_AppointmentEdited" 12.                  AppointmentDeleted="xJobsScheduler_AppointmentDeleted"> 13.</telerikScheduler:RadScheduler> Easy, right?  Otherwise, all the same styling in UserControl.Resources was re-used, right down to the DataContextProxy that lets us bind to a collection from our viewmodel (in this case, our code-behind) to use within the DataTemplate.  The code conversion gets even easier, as I could literally copy and paste almost everything from the ViewModel to my Code-Behind, just a matter of pasting the right section into the right event.  Here's the code-behind as proof: 001.public partial class SchedulingView : UserControl, INotifyPropertyChanged 002.{ 003.    public RecruitingContext context;

So what have we learned here today?  One, for the most part this MVVM thing is somewhat easy.  Yeah, you sometimes have to write a bunch of extra code, but with the help of a few useful snippits you can turn the process into a pretty streamlined little workflow.  Heck, this story gets even easier as you can see in this blog post by Michael Washington- specifically run a find on 'InvokeCommandAction' and you'll see the section regarding the command on TreeView in Blend 4.  Brilliant!  MVVM never looked so sweet! Otherwise, it is business as usual with RadScheduler for Silverlight whichever path you're choosing for your development.  Between now and the next post, I'll be cleaning up styles a bit (those RadComboBoxes are a little too close to my labels!) and adding some to the RowDetailsViews for Applicants and Jobs, so you can see all the info for an appointment in the dropdown tab view.  Otherwise, we're about ready to call a wrap on this oneDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Silverlight Recruiting Application Part 6 - Adding an Interview Scheduling Module/View

  Between the last post and this one I went ahead and carried the ideas for the Jobs module and view into the Applicants module and view- they're both doing more or less the same thing, except with different objects being at their core.  Made for an easy cut-and-paste operation with a few items being switched from one to another.  Now that we have the ability to add postings and applicants, wouldn't it be nice if we could schedule an interview?  Of course it would! Scheduling Module I think you get the drift from previous posts that these project structures start looking somewhat similar.  The interview scheduling module is no different than the rest- it gets a SchedulingModule.cs file at the root that inherits from IModule, and there is a single SchedulerView.xsml and SchedulerViewModel.cs setup for our V+VM.  We have one unique concern as we enter into this- RadScheduler deals with AppointmentsSource, not ItemsSource, so there are some special considerations to take into account when planning this module. First, I need something which inherits from AppointmentBase.  This is the core of the RadScheduler appointment, and if you are planning to do any form of custom appointment, you'll want it to inherit from this.  Then you can add-on functionality as needed.  Here is my addition to the mix, the InterviewAppointment: 01.public class InterviewAppointment : AppointmentBase 02.{ 03.    private int _applicantID; 04.    public int ApplicantID 05.    { 06.        get { return this._applicantID; } 07.        set 08.        { 09.            if (_applicantID != value) 10.            { 11.                _applicantID = value; 12.                OnPropertyChanged("ApplicantID"); 13.            } 14.        } 15.    } 16.   17.    private int _postingID; 18.    public int PostingID 19.    { 20.        get { return _postingID; } 21.        set 22.        { 23.            if (_postingID != value) 24.            { 25.                _postingID = value; 26.                OnPropertyChanged("PostingID"); 27.            } 28.        } 29.    } 30.   31.    private string _body; 32.    public string Body 33.    { 34.        get { return _body; } 35.        set 36.        { 37.            if (_body != value) 38.            { 39.                _body = value; 40.                OnPropertyChanged("Body"); 41.            } 42.        } 43.    } 44.   45.    private int _interviewID; 46.    public int InterviewID 47.    { 48.        get { return _interviewID; } 49.        set 50.        { 51.            if (_interviewID != value) 52.            { 53.                _interviewID = value; 54.                OnPropertyChanged("InterviewID"); 55.            } 56.        } 57.    } 58.   59.    public override IAppointment Copy() 60.    { 61.        IAppointment appointment = new InterviewAppointment(); 62.        appointment.CopyFrom(this);             63.        return appointment; 64.    } 65.   66.    public override void CopyFrom(IAppointment other) 67.    {             68.        base.CopyFrom(other); 69.        var appointment = other as InterviewAppointment; 70.        if (appointment != null) 71.        { 72.            ApplicantID = appointment.ApplicantID; 73.            PostingID = appointment.PostingID; 74.            Body = appointment.Body; 75.            InterviewID = appointment.InterviewID; 76.        } 77.    } 78.} Nothing too exciting going on here, we just make sure that our custom fields are persisted (specifically set in CopyFrom at the bottom) and notifications are fired- otherwise this ends up exactly like the standard appointment as far as interactions, etc.  But if we've got custom appointment items... that also means we need to customize what our appointment dialog window will look like. Customizing the Edit Appointment Dialog This initially sounds a lot more intimidating than it really is.  The first step here depends on what you're dealing with for theming, but for ease of everything I went ahead and extracted my templates in Blend for RadScheduler so I could modify it as I pleased.  For the faint of heart, the RadScheduler template is a few thousand lines of goodness since there are some very complex things going on in that control.  I've gone ahead and trimmed down the template parts I don't need as much as possible, so what is left is all that is relevant to the Edit Appointment Dialog.  Here's the resulting Xaml, with line numbers, so I can explain further: 001.<UserControl.Resources> 002.    <!-- begin Necessary Windows 7 Theme Resources for

template. Where we start getting into the dialog in question is line 132, but line 407 is where things start getting interesting.  The ItemsSource is pointing at a list that exists in my ViewModel (or code-behind, if it is used as a DataContext), the SelectedValue is the item I am actually binding from the applicant (note the TwoWay binding), and SelectedValuePath and DisplayMemberPath ensure the proper applicant is being displayed from the collection.  You will also see similar starting on line 420 where I do the same for the Jobs we'll be displaying. Just to wrap-up the Xaml, here's the RadScheduler declaraction that ties this all together and will be the main focus of our view: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.                  Grid.Row="1" 03.                  Grid.Column="1" 04.                  Width="800" 05.                  MinWidth="600" 06.                  Height="500" 07.                  MinHeight="300" 08.                  AppointmentsSource="{Binding Interviews}" 09.                  EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 10.                  command:AppointmentAddedEventClass.Command="{Binding AddAppointmentCommand}" 11.                  command:ApptCreatedEventClass.Command="{Binding ApptCreatingCommand}" 12.                  command:ApptEditedEventClass.Command="{Binding ApptEditedCommand}" 13.                  command:ApptDeletedEventClass.Command="{Binding ApptDeletedCommand}"> 14.</telerikScheduler:RadScheduler> Now, we get to the ViewModel and what it takes to get that rigged up.  And for those of you who remember the jobs post, those command:s in the Xaml are pointing to attached behavior commands that reproduce the respective events.  This becomes very handy when we're setting up the code-behind version. ;) ViewModel I've been liking this approach so far, so I'm going to put the entire ViewModel here and then go into the lines of interest.  Of course, feel free to ask me questions about anything that isn't clear (by line number, ideally) so I can help out if I have missed anything important: 001.public class SchedulerViewModel : ViewModelBase 002.{ 003.    private readonly IEventAggregator eventAggregator;

4.    base.ExecuteCommand(); 5.} And the ViewModel is none the wiser, the appointments just work as far as it is concerned since as they are created they become InterviewAppointments.  End result?  I've customized my EditAppointmentDialog as follows: And adding, editing, and deleting appointments works like a charm.  I can even 'edit' by moving appointments around RadScheduler, so as they are dropped into a timeslot they perform their full edit routine and things get updated. And then, the Code-Behind Version Perhaps the thing I like the most about doing one then the other is I get to steal 90% or more of the code from the MVVM version.  For example, the only real changes to the Code-Behind Xaml file exist in the control declaration, in which I use events instead of attached-behavior-event-commands: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.                  Grid.Row="1" 03.                  Grid.Column="1" 04.                  Width="800" 05.                  MinWidth="600" 06.                  Height="500" 07.                  MinHeight="300" 08.                  EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 09.                  AppointmentAdded="xJobsScheduler_AppointmentAdded" 10.                  AppointmentCreating="xJobsScheduler_AppointmentCreating" 11.                  AppointmentEdited="xJobsScheduler_AppointmentEdited" 12.                  AppointmentDeleted="xJobsScheduler_AppointmentDeleted"> 13.</telerikScheduler:RadScheduler> Easy, right?  Otherwise, all the same styling in UserControl.Resources was re-used, right down to the DataContextProxy that lets us bind to a collection from our viewmodel (in this case, our code-behind) to use within the DataTemplate.  The code conversion gets even easier, as I could literally copy and paste almost everything from the ViewModel to my Code-Behind, just a matter of pasting the right section into the right event.  Here's the code-behind as proof: 001.public partial class SchedulingView : UserControl, INotifyPropertyChanged 002.{ 003.    public RecruitingContext context;

So what have we learned here today?  One, for the most part this MVVM thing is somewhat easy.  Yeah, you sometimes have to write a bunch of extra code, but with the help of a few useful snippits you can turn the process into a pretty streamlined little workflow.  Heck, this story gets even easier as you can see in this blog post by Michael Washington- specifically run a find on 'InvokeCommandAction' and you'll see the section regarding the command on TreeView in Blend 4.  Brilliant!  MVVM never looked so sweet! Otherwise, it is business as usual with RadScheduler for Silverlight whichever path you're choosing for your development.  Between now and the next post, I'll be cleaning up styles a bit (those RadComboBoxes are a little too close to my labels!) and adding some to the RowDetailsViews for Applicants and Jobs, so you can see all the info for an appointment in the dropdown tab view.  Otherwise, we're about ready to call a wrap on this oneDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• straight to grub prompt on boot

  - by cheshirekow

  I am very lost. I did a fresh install of Ubuntu 10.04 on a laptop. First reboot was fine. I ran all the recommended upgrades, and now every time I start I get just a grub>_ prompt. No error message, just the prompt, and a little banner at the top saying grub's version and telling me that I have minimal bash style editing. I've tried: 1) Re-installing grub via sudo grub-install sda (There is only one disk with only two partitions, one primary, and one for swap) 2) Changed GRUB_HIDDEN_TIMEOUT=10 GRUB_TIMEOUT=30 GRUB_CMDLINE_LINUX_DEFAULT="rootdelay=90" GRUB_CMDLINE_LINUX="rootdelay=90" in /etc/default/grub. No luck.

• OpenVPN on Ubuntu 11.10 - unable to redirect default gateway

  - by Vladimir Kadalashvili

  I'm trying to connect to connect to OpenVPN server from my Ubuntu 11.10 machine. I use the following command to do it (under root user): openvpn --config /home/vladimir/client.ovpn Everything seems to be OK, it connects normally without any warnings and errors, but when I try to browse the internet I see that I still use my own IP address, so VPN connection doesn't work. When I run openvpn command, it displays the following message among others: NOTE: unable to redirect default gateway -- Cannot read current default gateway from system I think it's the cause of this problem, but unfortunately I don't know how to fix it.

• Can connect to Samba server but cannot access shares?

  - by jlego

  I have setup a stand-alone box running Fedora 16 to use as a file-sharing and web development server. Needs to be able to share files with a PC running Windows 7 and a Mac running OSX Snow Leopard. I've setup Samba using the Samba configuration GUI tool. Added users to Fedora and connected them as Samba users (which are the same as the Windows and Mac usernames and passwords). The workgroup name is the same as the Windows workgroup. Authentication is set to User. I've allowed Samba and Samba client through the firewall and set the ethernet to a trusted port in the firewall. Both the Windows and Mac machines can connect to the server and view the shares, however when trying to access the shares, Windows throws error 0x80070035 " Windows cannot access \SERVERNAME\ShareName." Windows user is not prompted for a username or password when accessing the server (found under "Network Places"). This also happens when connecting with the IP rather than the server name. The Mac can also connect to the server and see the shares but when choosing a share gives the error "The original item for ShareName cannot be found." When connecting via IP, the Mac user is prompted for username and password, which when authenticated gives a list of shares, however when choosing a share to connect to, the error is displayed and the user cannot access the share. Since both machines are acting similarly when trying to access the shares, I assume it is an issue with how Samba is configured. smb.conf: [global] workgroup = workgroup server string = Server log file = /var/log/samba/log.%m max log size = 50 security = user load printers = yes cups options = raw printcap name = lpstat printing = cups [homes] comment = Home Directories browseable = no writable = yes [printers] comment = All Printers path = /var/spool/samba browseable = yes printable = yes [FileServ] comment = FileShare path = /media/FileServ read only = no browseable = yes valid users = user1, user2 [webdev] comment = Web development path = /var/www/html/webdev read only = no browseable = yes valid users = user1 How do I get samba sharing working? UPDATE: Before this box I had another box with the same version of fedora installed (16) and samba working for these same computers. I started up the old machine and copied the smb.conf file from the old machine to the new one (editing the share definitions for the new shares of course) and I still get the same errors on both client machines. The only difference in environment is the hardware and the router. On the old machine the router received a dynamic public IP and assigned dynamic private IPs to each device on the network while the new machine is connected to a router that has a static public IP (still dynamic internal IPs though.) Could either one of these be affecting Samba? UPDATE 2: As the directory I am trying to share is actually an entire internal disk, I have tried to things: 1.) changing the owner of the mounted disk from root to my user (which is the same username as on the Windows machine) 2.) made a share that only included one of the folders on the disk instead of the entire disk with my user again as the owner. Both tests failed giving me the same errors regarding the network address. UPDATE 3: Not sure exactly what I did, but now whenever I try to connect to the share on the Windows 7 client I am prompted for my username and password. When I enter the correct credentials I get an access denied message. However I did notice that under the login box "domain: WINDOWS-PC-NAME" is listed. I believe this could very well be the problem. Any suggestions? UPDATE 4: So I've completely reinstalled Fedora and Samba now. I've created a share on the first harddrive (one fedora is installed on) and I can access that fine from Windows. However when I try to share any data on the second disk, I am receiving the same error. This I believe is the problem. I think I need to change some things in fstab or fdisk or something. UPDATE 5: So in fstab I mapped the drive to automount in a folder which works correctly. I also added the samba_share_t SElinux label to the mountpoint directory which now allows me to access the shares on the Windows machine, however I cannot see any of the files in the directory on the windows machine. (They are there, I can see them in the fedora file browser locally) UPDATE 6: Figured it out. See answer below

• Active directory authentication for Ubuntu Linux login and cifs mounting home directories...

  - by Jamie

  I've configured my Ubuntu 10.04 Server LTS Beta 2 residing on a windows network to authenticate logins using active directory, then mount a windows share to serve as there home directory. Here is what I did starting from the initial installation of Ubuntu. Download and install Ubuntu Server 10.04 LTS Beta 2 Get updates # sudo apt-get update && sudo apt-get upgrade Install an SSH server (sshd) # sudo apt-get install openssh-server Some would argue that you should "lock sshd down" by disabling root logins. I figure if your smart enough to hack an ssh session for a root password, you're probably not going to be thwarted by the addition of PermitRootLogin no in the /etc/ssh/sshd_config file. If your paranoid or not simply not convinced then edit the file or give the following a spin: # (grep PermitRootLogin /etc/ssh/sshd_conifg && sudo sed -ri 's/PermitRootLogin ).+/\1no/' /etc/ssh/sshd_conifg) || echo "PermitRootLogin not found. Add it manually." Install required packages # sudo apt-get install winbind samba smbfs smbclient ntp krb5-user Do some basic networking housecleaning in preparation for the specific package configurations to come. Determine your windows domain name, DNS server name, and IP address for the active directory server (for samba). For conveniance I set environment variables for the windows domain and DNS server. For me it was (my AD IP address was 192.168.20.11): # WINDOMAIN=mydomain.local && WINDNS=srv1.$WINDOMAIN If you want to figure out what your domain and DNS server is (I was contractor and didn't know the network) check out this helpful reference. The authentication and file sharing processes for the Windows and Linux boxes need to have their clocks agree. Do this with an NTP service, and on the server version of Ubuntu the NTP service comes installed and preconfigured. The network I was joining had the DNS server serving up the NTP service too. # sudo sed -ri "s/^(server[ \t]).+/\1$WINDNS/" /etc/ntp.conf Restart the NTP daemon # sudo /etc/init.d/ntp restart We need to christen the Linux box on the new network, this is done by editing the host file (replace the DNS of with the FQDN of the windows DNS): # sudo sed -ri "s/^(127\.0\.0\.1[ \t]).*/\1$(hostname).$WINDOMAIN localhost $(hostname)/" /etc/hosts Kerberos configuration. The instructions that follow here aren't to be taken literally: the values for MYDOMAIN.LOCAL and srv1.mydomain.local need to be replaced with what's appropriate for your network when you edit the files. Edit the (previously installed above) /etc/krb5.conf file. Find the [libdefaults] section and change (or add) the key value pair (and it is in UPPERCASE WHERE IT NEEDS TO BE): [libdefaults] default_realm = MYDOMAIN.LOCAL Add the following to the [realms] section of the file: MYDOMAIN.LOCAL = { kdc = srv1.mydomain.local admin_server = srv1.mydomain.local default_domain = MYDOMAIN.LOCAL } Add the following to the [domain_realm] section of the file: .mydomain.local = MYDOMAIN.LOCAL mydomain.local = MYDOMAIN.LOCAL Conmfigure samba. When it's all said done, I don't know where SAMBA fits in ... I used cifs to mount the windows shares ... regardless, my system works and this is how I did it. Replace /etc/samba/smb.conf (remember I was working from a clean distro of Ubuntu, so I wasn't worried about breaking anything): [global] security = ads realm = MYDOMAIN.LOCAL password server = 192.168.20.11 workgroup = MYDOMAIN idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes template homedir = /home/%D/%U template shell = /bin/bash client use spnego = yes client ntlmv2 auth = yes encrypt passwords = yes winbind use default domain = yes restrict anonymous = 2 Start and stop various services. # sudo /etc/init.d/winbind stop # sudo service smbd restart # sudo /etc/init.d/winbind start Setup the authentication. Edit the /etc/nsswitch.conf. Here are the contents of mine: passwd: compat winbind group: compat winbind shadow: compat winbind hosts: files dns networks: files protocols: db files services: db files ethers: db files rpc: db files Start and stop various services. # sudo /etc/init.d/winbind stop # sudo service smbd restart # sudo /etc/init.d/winbind start At this point I could login, home directories didn't exist, but I could login. Later I'll come back and add how I got the cifs automounting to work. Numerous resources were considered so I could figure this out. Here is a short list (a number of these links point to mine own questions on the topic): Samba Kerberos Active Directory WinBind Mounting Linux user home directories on CIFS server Authenticating OpenBSD against Active Directory How to use Active Directory to authenticate linux users Mounting windows shares with Active Directory permissions Using Active Directory authentication with Samba on Ubuntu 9.10 server 64bit How practical is to authenticate a Linux server against AD?

• How to make sure that grub does use menu.lst?

  - by Glen S. Dalton

  On my Ubuntu 9.04 ("Karmic") laptop I suspect grub does not use the /boot/grub/menu.lst file. What happens on boot is that I see a blank screen and nothing happens. When I press ESC I see a boot list which is different from what I would expect from the menu.lst file. The menu lines are different and when I choose the first entry it does not use the kernel options that are in the first entry in menu.lst. Where do the entries that grub uses come from? How can I find out what happens, is there a log? I could not find anything in /var/log/syslog or /var/log/dmesg about grub using a menu.lst. How can I set it to work like expected?
