• Ubuntu Server Wireless connection issue - replaced router but kept ESSID

  - by Stevo

  I have a ubuntu server 12.04 which was connected to my wireless network with no problem I replaced the wireless router but kept the ESSID and password the same. All other devices on network have connected correctly. However the Ubuntu Server will not route correctly. It will connect to the wifi router, and get a dhcp served IP address, however it will not route anything. I cannot ping the router from the server. the contents of /etc/resolve.conf are updated with the information from the router, (the host name has been served) I know there is nothing wrong with the router or the server, or the wireless card etc. I'm assuming there's some cached setting that associates the old router with the ESSID and causing the issue. I've got a lot of other devices connected to the router, so don't want to change the name of the ESSID. How do I fix this? EDIT: outputs (abbreviated as I've got no cut and paste) netstat -rn: Kernel IP Routing table Dest Gate Gen Flags MSS Window irtt Iface 0.0.0.0 192.168.0.1 0.0.0.0.

• What user information is exposed via a browser?

  - by ipso

  Is there a function or website that can collect and display ALL of the user information that can be obtained via a browser? Background: This of course does not account for the significant cross-reference abilities of large corporations to collate multiple sources and signals from users across various properties, but it's a first step. Ghostery is just a great idea; to show people all of the surreptitious scripts that run on any given website. But what information is available – what is the total set of values stored – that those scripts can collect from? If you login to a search engine and stay logged in but leave their tab, is that company still collecting your webpage viewing and activity from other tabs? Can past or future inputs to pages be captured – say comments on another website? What types of activities are stored as variables in the browser app that can be collected? This is surely a highly complex question, given to countless user scenarios – but my whole point is to be able to cut through all that – and just show the total set of data available at any given point in time. Then you can A/B test and see what is available with in a fresh session with one tab open vs. the same webpage but with 12 tabs open, and a full day of history to boot. (Latest Firefox & Chrome – on Win7, Win8 or Mint13 – although I'd like to think that won't make too much of a difference. Make assumptions. Simple is better.)

• Limited bandwidth and transfer rates per user.

  - by Cx03

  I searched for a while but couldn't find anything concrete, hopefully someone can help me. I'm going to be running a Debian server on a gigabit port, and want to give each user his/her fair share of internet access. The first objective is easy - transfer rates (speed) per user. From what I've looked at, IPTables/Shorewall could do the job easy. Is this easy to setup, or could one of you point me at a config? I was hoping to limit users at 300mbit or 650mbit each. The second objective gets complicated. Due to the usage of the boxes, most of the traffic will be internal network traffic that does NOT get counted to the quota. However, I still need to limit the external traffic, and if they go over, cut off access (or throttle traffic to a very low speed (10mbit?)). Let's say the user has a 3TB external traffic limit. The IF part is: If the hostname they are exchanging the traffic with DOES NOT MATCH .ovh. or .kimsufi. (company owns multiple TLDs), count to the quota. Once said quota exceeds 3TB, choke them. Where could I find a system to count that for me? It would also need to reset or be able to be manually reset on a monthly basis. Thanks ahead of time!

• Migrating ODBC information through a batch file

  - by DeskSide

  I am a desktop support technician currently working on a large scale migration project across multiple sites. I am looking at a way to transfer ODBC entries from Windows XP to Windows 7. If anyone knows of a program or anything prebuilt that already does this, please redirect me. I've already looked but haven't found anything, so I'm trying to build my own. I know enough basic programming to read the work of others and monkey around with something that already exists, but not much else. I have come across a custom batch file written at one site that (among other things) exports ODBC information from the old computer and stores it on a server (labelled as y: through net use at the beginning of the file), then later transfers it from the server to a new computer. The pre-existing code is for Windows XP to XP migrations. Here are the pertinate bits of code: echo Exporting ODBC Information start /wait regedit.exe /e "y:\%username%\odbc.reg" HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI (and later on) echo Importing ODBC start /wait regedit /s "y:\%username%\odbc.reg" We are now migrating from Windows XP to 7, and this part of the batch file still seems to work for this particular site, where Oracle 8i and 10g are used. I'm looking to use my cut down version of this code at multiple sites, and I'm wondering if the same lines of code will still work for anything other than Oracle. Also, my research on this issue has shown that there are different locations in 64 bit operating systems for 32/64 bit entries, and I'm wondering what effect that would have on the code. Could I copy the same data to both parts of the registry, in hopes of catching everything? Any assistance would be appreciated. Thank you for your time.

• Installing a new Motherboard in a HP xw6200 case

  - by thing2k

  I have a HP xw6200 Workstation, that is rather long in the tooth, and with 2 physical CPUs, it is quite inefficient. So, the plan was to upgrade the internals. Nothing special: AMD Athlon II X4 640 ASUS M4A78KT-M LE (mATX) 2x 2GB DDR3 1333MHz RAM. 3p under my £150 budget The issues: The pin connector for the front panel isn't a good fit, but I can trim it to size. The PSU has a 8-Pin Power connector, unsurprisingly, the new board has a 4 pin socket. The pins do line up, but I would have to cut it in half to fit. Finally, due to the weight of heat-sinks, they are screwed directly into the case. It turns out that these screws also lock the motherboard in place. As to remove it, you remove the heat-sinks, slide the motherboard across and lift it out. I tested the new board for fit, and while it slots in fine, it's not secure. There is nowhere to screw the board down, it is just held in place with plastic standoffs. The only idea I had, was to wedging something between the side of the motherboard and part of the case. Any suggestions?

• Is domain-transfer inherently safe for downtime when the name servers remain the same?

  - by jlmt

  I've been reading around this topic towards understanding whether there's some or no chance of downtime during an upcoming domain transfer for 15 live and very critical domains. In our case there are three companies involved: CompanyA is the original registrar and DNS host, CompanyB is the new DNS host, and CompanyC is the new registrar. I've already changed the nameservers for all domains to those of CompanyB. We suffered some downtime because CompanyA deleted their hosted DNS for our domains directly after the change, but the changes propagated and we're now able to configure our DNS with CompanyB. From what I understand (please correct where wrong!): There exists an SOA record that points oneofourdomains.com to ns.companyb.com. That record is maintained and authoritatively hosted by the ccTLD registry for the domain (eg. Verisign for .com). CompanyA currently has the ability to change the SOA record because they're the registrar. There exist NS records for oneofourdomains.com, which are also related to the link from domain name to nameserver, are similarly hosted by the ccTLD, and which CompanyA are also able to change while acting as registrar. Neither CompanyB nor CompanyC currently have any control over the SOA or NS records. CompanyA are unable to cause us (DNS) problems during the transfer by dropping service early, because they are not the authoritative source for the SOA and NS records. When we transfer the domains, it's administrative control of the SOA and NS records that will be transferred to CompanyC. As long as we advise CompanyC that the SOA and NS records must not change (as regards pointing to CompanyB's nameservers), there's no need for any kind of DNS change, and therefore no possibility of downtime. Is my understanding of this correct? My fear is that CompanyA will somehow cut us off again, and their support dept hasn't given me much confidence in their understanding of the topic.

• Silent install of Japanese Language Pack in Win7

  - by Doltknuckle

  Every year, due to re-imaging, I am forced to find a way to install the Japanese language pack on a collection of 30 computers. Each year I look for a way to automate this process, and each year I am forced to do this manually. Maybe this year will be different. Has anyone had any luck with installing and configuring far east language support for windows 7 without user interaction? I have already downloaded kb972813 and have a way to get it out to the computers. What I normally do is this: Run the EXE, use the default settings. Open up language settings and create the JP keyboard. Configure the language bar settings. Copy settings to default user. Delete the local user cache. Sign the different user accounts in to make sure that the default settings are correct. This whole process takes about 10 minutes, multiply that out by 30 machines and you are looking at a 5 hour process. If I can log into all of the computers at once, I can normally cut that down to about an hour. Any ideas would be appreciated. Thanks in advance

• Euro character messed up during FTP transfer

  - by djechelon

  My customer is using a very outdated ecommerce management system on my hosting service. For that product, no support is being provided anymore by the vendor. Brief explanation: the shop website, that claims to run under LAMP stack, is built by an old Visual Basic Windows application running on MS Access. The user constructs the shop, defines the HTML template, adds products and categories, etc. Then the VB exe builds the PHP pages (one for each template page) and the SQL script to run on MySQL. It also uploads everything via FTP and runs the installation/upgrade script on its own. The problem Browsing the website, many products' descriptions are cut before the euro sign. For example, what was supposed to be "Product price €1000" becomes "Product price" The analysis MySQL contains a cutted description until the € sign, so it's not PHP fault The Access databases contain full description with € sign, so it's not fault of the webmaster writing bad description or eDisplay cutting them The SQL that will run once the site gets uploaded, stored on my local machine before upload, contains the € sign The same script, after being FTPed by eDisplay and opened with nano from SSH, shows the € sign messed up like this: ^À vsftpd log reports (obfuscated for privacy) Sat Dec 15 11:16:57 2012 22 xxx.xxx.128.13 1112727 /srv/www/domains/xxxxxx.it/htdocs/db.sql b _ i r xxxxxxx ftp 0 * c which seems to be a binary transfer (and also a huge security vulnerability because you can download the whole database from unauthenticated HTTP) The eDisplay internal FTP client provides no option for ascii/binary transfer modes [Add] Trying to manually upload the SQL file via SFTP shows messing up euro [Add2] Trying to manually upload using Xftp client with explicit ASCII mode doesn't fix too It looks like the file gets uploaded as binary. Perhaps on the customer's previous host it all worked fine because that was a Windows host. The server It's an Azure virtual machine running openSUSE 12.2 with both vsftpd and openSSH The question Without asking the customer to manually upload files using FileZilla or replacing € with &euro;, because he refuses, what can I do on server side to prevent vsftpd to screw up euro sign?

• How should an experienced Windows SysAdmin learn Linux? [closed]

  - by Systemspoet

  I have a new hire starting in a few weeks who is an experienced Windows SysAdmin. I think he's fairly senior on the Windows side, with a pretty deep AD understanding and experience with Exchange 2007, 2010, and exchange migrations. He's done a little PowerShell but I suspect more of the "run this command to do this" variety then "write a script to do this" sort. However, we are a mixed shop and (he knows this) I expect him to become a reasonably competent Linux SysAdmin over time. I'm looking for good starting points to bring him along. I have over ten years of Linux/UNIX experience, so it all sort of seems intuitive to me, but I've been thinking about the toolkit you actually need to be productive in the Linux CLI world. Just to be able to use the machines at all, off the top of my head... vi Basic CLI stuff -- move around, rename files, copy files, tar, gzip, changing passwords, finding relevant manpages, keep track of where you are, find things in your history, etc, etc. More advanced things that I take for granted but are actually pretty hard -- doing things with 'find', extracting relevant text via 'awk' and/or 'cut', knowing when to use 'grep' and when to use 'grep -e' or 'egrep'. Distribution specific stuff... compiling software, rpm, yum, apt-get, you name it. This all seems pretty basic to me, but when I think back to 1995 when I was first learning my way, some of those things took me years to master. So my question is -- where should I send him to pick up those skills? I'm not just thinking of classes, but rather also websites and books? Where do you all suggest as a starting point for picking up Linux skills?

• Server specification recommendation

  - by foo

  To cut the story short, I can't buy an item (server/cpu/motherboard/ram) that costs more than USD 330. However, I can combine them, meaning, I can buy a CPU that costs USD 330 and motherboard that costs USD 330. With this limitation, I can't buy a powerful 1U server which will definitely costs me more USD 330. With that in mind, I was hoping to build a powerful desktop PC which will be used as a database server. However, through my experience, desktop PC doesn't last very long, usually the motherboard will just die by itself after 1 or 2 years. So, what would you guys recommend me to buy with this kind of budget? Every item must be <= USD 330. Will be used as a MySQL server. RAID would be nice. 1TB is pretty big for my data. I do not need external graphic card (onboard would do just fine), mouse, keyboard, monitor. Linux friendly. One ethernet port is good enough. It's important that those hardware is made of components that will last long (at least 3 years or something). The server will be placed in an air conditioned room, but a good ventilation for the server is always preferred. I won't overclock it. Intel processor is preferred. Thanks in advance.

• Two mouse, one left handed and another right handed. At the same time

  - by trailmax

  I would like to have two mouse connected to my computer, and have one mouse left-handed, another right-handed. And not needing to change any settings for using any of them. I've googled for this and did not find some information, but nothing helpful. Somebody suggested to have 2 accounts, some other suggested a short-cut that changes mouse buttons over. I did not like any of that. And I remember, I saw somebody using their laptop with right-handed touch-pad and left-handed mouse. At the same time. Both of my mouse are plain vanilla USB, with no drivers, tried finding drivers for any of the mouse did not get me anywhere. This is how mouse configuration looks like: There is no option for different mouse to be configured different. I think I need to install some mouse drivers/software that allow different configuration. Is there anything like this availble?? Many thanks in advance! p.s. Using Windows 7 Pro, one mouse is Fujitsu, another Sandsrom.

• Raspberry Pi how to format HDD

  - by Speed

  Hi I am very new to Raspberry Pi environment, so looking for a bit of help to format a usb hard disk drive. I ran lsblk and got sda 8:0 0 37.3G 0 disk sda1 8:1 0 37.3G 0 part looking on web, if tried the following "sudo mkfs.ext4 /dev/sda1 -L USB40gb" it did something but when I tried to mount the drive again, it still showed the files that were there before and I can not create new file/folder "Error creating directory: Permission denied" I am writing this from my windows 8.1 pc so can not cut and paste from the pi. trying to format its output is a bit hard. Oh, there is Nothing written after the word "part" above. There use to be /media/USB40gb so I have done something because this has disappeared. I am using PCManFM 0.9.10 It does not have a format option, which would make life a lot easier, but then its not windows. I think I am running the basic linux os for the pi. It boots to a graphic environment, but I do not know how to advise what it is. I think its OpenBox 2.0.4 Thanks in advance Speed PS: I reran the format string above but this time I changed the label to read USB37gb. I did this to confirm that I was in fact formatting the right drive. Low and behold, it actually formatted the drive, wiping everything from it. Great ... testing it by creating a new folder on the drive and get error msg Permission Denied! So I have fixed the formatting issue by trial and error but still can't use the drive... Suggestions anyone?

• Webcast Q&A: Los Angeles Department of Building & Safety Lowers Customer Service Costs with Oracle WebCenter

  - by Kellsey Ruppel

  This week we had the fifth webcast in our WebCenter in Action webcast series, "Los Angeles Department of Building & Safety Lowers Customer Service Costs with Oracle WebCenter", where customers Giovani Dacumos and Minh Ong from the Los Angeles Department of Building & Safety (LADBS), and Sheetal Paranjpye and Rajiv Desai from Oracle Partner 3Di, shared how Oracle WebCenter is powering LADBS' externally facing website and providing a superior self-service experience for their customers. We asked the speakers to provide some dialogue for Q&A.   Giovani Dacumos, Director of Systems and Minh Ong, LADBS Q: Did you run into any issues when integrating all of the different applications together?A: Yes. We did have issues integrating a secure sign on between the portal and other legacy applications. We used portlets and iframes to overcome those.  This is a new technology for us and we are also learning as we go so there were a lot of challenges in developing and implementing our vision. Q: What has been the biggest benefit your end users have seen?A: The biggest benefit for our ends users is ease-of-use. We've given them a system that provided a new and improved source of information, as well as a very organized flow of transaction processing. It has made our online service very user friendly. Q: Was there any resistance internally when implementing the solution? If so, how did you overcome that?A: There was no internal resistance during the implementation, only challenges. As mentioned earlier, this is a new technology for us. We've come across issues that needed assistance from Oracle. Working with 3Di and Oracle has helped us tremendously to find solutions to our implementation issues. Q: Given the performance, what do you estimate to be the top end capacity of the system? A: With the current performance and architecture we have, we are able to support approx 300-400 concurrent users.  We would need more hardware to support additional user load. Q: What's the overview or summary of feedback from the users interacting with the site?A: LADBS has a wide spectrum of customers, from simple users like homeowners to large construction firms. Anything new that we offer could be a little bit challenging for some, but overall, the customers liked it. They saw a huge improvement on the usability. Q: Can you describe the impressions about the site before and after the project within LADBS?A: The old site was using old technology and it was hard for us to keep on building into it as we got more business requirements. It made our application seem a bit complicated.  It was confusing for our new customers to use and we've improved on this with the new site. It's now easier for them to complete their transactions and, at the same time, allowed us to provide more useful information. Sheetal Paranjpye and Rajiv Desai, 3Di Q: Did you run into any obstacles when implementing the solution?A: Yes we did run into some obstacles. One of the key show stoppers was the issue with portlet to portal communication. The GIS viewer (portlet) needed information to be passed  to and from Permit LA (Portal), but we were able to get everything configured and up and working quickly! Q: Was there a lot of custom work that needed to be done for this particular solution?A: We have done some customizations where workflows/ Task flows are involved.  Q: What do you think were the keys to success for rolling out WebCenter?A: Having a service oriented architecture and using portlets have been the key areas for rolling out Oracle WebCenter at LADBS. The Oracle WebCenter Content integration allows the flexibility to business users to maintain the content, which has really cut down on the reliance of IT, and employee productivity has increased as a result. If you missed the webcast, be sure to catch the replay to see a live demonstration of WebCenter in action!

  If you are a regular reader of this blog, you might know that I travel nearly 20+ days out of 30 days in a month. There are cases when I don’t have a chance to go home for an entire month and my family has to travel to different cities just to meet me. During my recent visit, one of my acquaintances suggested that I should blog about my travel experiences as well. This can be helpful to others who are traveling to the country or city. I have previously written about my experience about all the airlines in India. I would be writing about a few tips about traveling to the beautiful country Nepal today. Kathmandu, the capital of Nepal is very scenic. There are lots of historical places to see and visit. I was fortunate enough to stopover the Pashupatinath Temple, Bhaktapur, Vasantpur and the temple of Kumari Goddess. I also visited casinos there, but even if  I have stayed in Las Vegas for 3 and a half years before, I was not keen on them so I left the casinos just like what I did in Las Vegas . I also traveled to the famous Thamel area by car. Here are my quick tips for anyone who is planning to visit Nepal. They are not categorized but just written in the order that came to my mind. Please note that if you are an Indian, you will get a special privilege everywhere in Nepal, beginning right from the Indian airports. Use the expression “Nameste!” If you want to greet any Indian or Nepali. Indian Nationals do not need visa/passport to enter Nepal. In fact, Indian Nationals can just walk in to Nepal without any passport; but should have any valid Indian ID. There is no use of a passport since it will not be stamped at any immigration ports, whether in India or Nepal. Indian currency is widely accepted everywhere. However, please bring only Rs. 100 bills/notes as Rs. 500 or Rs. 1000 are not accepted. However, casinos there will accept larger bills. Indian National Language – Hindi is widely spoken and understood everywhere. I did not find a single person who had trouble speaking it. Nepali language uses the scripting language as Devnagari, which is similar to Hindi. Here, you will find food of almost every country.  The taste of Nepali food is authentic and very delicious. It is very safe to travel and move around in Kathmandu (despite what media suggests). However, it will really help if you have a friend who speaks Nepali. You can negotiate a few deals and cut off to almost 1/5 of the original quoted price of products sold here. If you are from Gujarat, India – you will find Nepali language sharing many common words. Temples are everywhere, so do not miss to visit a few of them. Pashupatinath is a must. Only followers of Hindu religion (from Nepal and India only) are allowed in most of the holy places. Camera is allowed everywhere except on the holy places. Now it is your turn to share your opinions or any suggestions. I think Nepal is a great country as there are lots of places to visit.

• Automatic Properties, Collection Initializers, and Implicit Line Continuation support with VB 2010

  - by ScottGu

  [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] This is the eighteenth in a series of blog posts I’m doing on the upcoming VS 2010 and .NET 4 release. A few days ago I blogged about two new language features coming with C# 4.0: optional parameters and named arguments.  Today I’m going to post about a few of my favorite new features being added to VB with VS 2010: Auto-Implemented Properties, Collection Initializers, and Implicit Line Continuation support. Auto-Implemented Properties Prior to VB 2010, implementing properties within a class using VB required you to explicitly declare the property as well as implement a backing field variable to store its value.  For example, the code below demonstrates how to implement a “Person” class using VB 2008 that exposes two public properties - “Name” and “Age”:   While explicitly declaring properties like above provides maximum flexibility, I’ve always found writing this type of boiler-plate get/set code tedious when you are simply storing/retrieving the value from a field.  You can use VS code snippets to help automate the generation of it – but it still generates a lot of code that feels redundant.  C# 2008 introduced a cool new feature called automatic properties that helps cut down the code quite a bit for the common case where properties are simply backed by a field.  VB 2010 also now supports this same feature.  Using the auto-implemented properties feature of VB 2010 we can now implement our Person class using just the code below: When you declare an auto-implemented property, the VB compiler automatically creates a private field to store the property value as well as generates the associated Get/Set methods for you.  As you can see above – the code is much more concise and easier to read. The syntax supports optionally initializing the properties with default values as well if you want to: You can learn more about VB 2010’s automatic property support from this MSDN page. Collection Initializers VB 2010 also now supports using collection initializers to easily create a collection and populate it with an initial set of values.  You identify a collection initializer by declaring a collection variable and then use the From keyword followed by braces { } that contain the list of initial values to add to the collection.  Below is a code example where I am using the new collection initializer feature to populate a “Friends” list of Person objects with two people, and then bind it to a GridView control to display on a page: You can learn more about VB 2010’s collection initializer support from this MSDN page. Implicit Line Continuation Support Traditionally, when a statement in VB has been split up across multiple lines, you had to use a line-continuation underscore character (_) to indicate that the statement wasn’t complete.  For example, with VB 2008 the below LINQ query needs to append a “_” at the end of each line to indicate that the query is not complete yet: The VB 2010 compiler and code editor now adds support for what is called “implicit line continuation support” – which means that it is smarter about auto-detecting line continuation scenarios, and as a result no longer needs you to explicitly indicate that the statement continues in many, many scenarios.  This means that with VB 2010 we can now write the above code with no “_” at all: The implicit line continuation feature also works well when editing XML Literals within VB (which is pretty cool). You can learn more about VB 2010’s Implicit Line Continuation support and many of the scenarios it supports from this MSDN page (scroll down to the “Implicit Line Continuation” section to find details). Summary The above three VB language features are but a few of the new language and code editor features coming with VB 2010.  Visit this site to learn more about some of the other VB language features coming with the release.  Also subscribe to the VB team’s blog to learn more and stay up-to-date with the posts they the team regularly publishes. Hope this helps, Scott

• Raspberry Pi entrance signed backed by Umbraco - Part 1

  - by Chris Houston

  Being experts on all things Umbraco, we jumped at the chance to help our client, QV Offices, with their pressing signage predicament. They needed to display a sign in the entrance to their building and approached us for our advice. Of course it had to be electronic: displaying multiple names of their serviced office clients, meeting room bookings and on-the-pulse promotions. But with a winding Victorian staircase and minimal storage space how could the monitor be run, updated and managed? That’s where we came in…Raspberry PiUmbraco CMSAutomatic updatesAutomated monitor of the signPower saving when the screen is not in useMounting the screenThe screen that has been used is a standard LED low energy Full HD screen and has been mounted on the wall using it's VESA mounting points, as the wall is a stud wall we were able to add an access panel behind the screen to feed through the mains, HDMI and sensor cables.The Raspberry Pi is then tucked away out of sight in the main electrical cupboard which just happens to be next to the sign, we had an electrician add a power point inside this cupboard to allow us to power the screen and the Raspberry Pi.Designing the interface and editing the contentAlthough a room sign was the initial requirement from QV Offices, their medium term goal has always been to add online meeting booking to their website and hence we suggested adding information about the current and next day's meetings to the sign that would be pulled directly from their online booking system.We produced the design and built the web page to fit exactly on a 1920 x 1080 screen (Full HD in Portrait)As you would expect all the information can be edited via an Umbraco CMS, they are able to add floors, rooms, clients and virtual clients as well as add meeting bookings to their meeting diary.How we configured the Raspberry PiAfter receiving a new Raspberry Pi we downloaded the latest release of Raspbian operating system and followed the official guide which shows how to copy the OS onto an SD card from a Mac, we then followed the majority of steps on this useful guide: 10 Things to Do After Buying a Raspberry Pi.Installing ChromiumWe chose to use the Chromium web browser which for those who do not know is the open sourced version of Google Chrome. You can install this from the terminal with the following command:sudo apt-get install chromium-browserInstalling UnclutterWe found this little application which automatically hides the mouse pointer, it is used in the script below and is installed using the following command:sudo apt-get install unclutterAuto start Chromium and disabling the screen saver, power saving and mouseWhen the Raspberry Pi has been installed it will not have a keyboard or mouse and hence if their was a power cut we needed it to always boot and re-loaded Chromium with the correct URL.Our preferred command line text editor is Nano and I have assumed you know how to use this editor or will be able to work it out pretty quickly.So using the following command:sudo nano /etc/xdg/lxsession/LXDE/autostartWe then changed the autostart file content to:@lxpanel --profile LXDE@pcmanfm --desktop --profile LXDE@xscreensaver -no-splash@xset s off@xset -dpms@xset s noblank@chromium --kiosk --incognito http://www.qvoffices.com/someURL@unclutter -idle 0The first few commands turn off the screen saver and power saving, we then open Cromium in Kiosk Mode (full screen with no menu etc) and pass in the URL to use (I have changed the URL in this example) We found a useful blog post with the Cromium command line switches.Finally we also open an application called Unclutter which auto hides the mouse after 0 seconds, so you will never see a mouse on the sign.We also had to edit the following file:sudo nano /etc/lightdm/lightdm.confAnd added the following line under the [SeatDefault] section:xserver-command=X -s 0 dpmsRefreshing the screenWe decided to try and add a scheduled task that would trigger Chromium to reload the page, at some point in the future we might well change this to using Javascript to update the content, but for now this works fine.First we installed the XDOTool which enables you to script Keyboard commands:sudo apt-get install xdotoolWe used the Refreshing Chromium Browser by Shell Script post as a reference and created the following shell script (which we called refreshing.sh):export DISPLAY=":0"WID=$(xdotool search --onlyvisible --class chromium|head -1)xdotool windowactivate ${WID}xdotool key ctrl+F5This selects the correct display and then sends a CTRL + F5 to refresh Chromium.You will need to give this file execute permissions:chmod a=rwx refreshing.shNow we have the script file setup we just need to schedule it to call this script periodically which is done by using Crontab, to edit this you use the following command:crontab -eAnd we added the following:*/5 * * * * DISPLAY=":.0" /home/pi/scripts/refreshing.sh >/home/pi/cronlog.log 2>&1This calls our script every 5 minutes to refresh the display and it logs any errors to the cronlog.log file.SummaryQV Offices now have a richer and more manageable booking system than they did before we started, and a great new sign to boot.How could we make sure that the sign was running smoothly downstairs in a busy office centre? A second post will follow outlining exactly how Vizioz enabled QV Offices to monitor their sign simply and remotely, from the comfort of their desks.

• Making a Job Change That's Easy Why Not Try a Career Change

  - by david.talamelli

  A few nights ago I received a comment on one of our blog posts that reminded me of a statistic that I heard a while back. The statistic reflected the change in our views towards work and showed how while people in past generations would stay in one role for their working career - now with so much choice people not only change jobs often but also change careers 4-5 times in their working life. To differentiate between a job change and a career change: when I say job change this could be an IT Sales person moving from one IT Sales role to another IT Sales role. A Career change for example would be that same IT Sales person moving from IT Sales to something outside the scope of their industry - maybe to something like an Engineer or Scuba Dive Instructor. The reason for Career changes can be as varied as the people who make them. Someone's motivation could be to pursue a passion or maybe there is a change in their personal circumstances forcing the change or it could be any other number of reasons. I think it takes courage to make a Career change - it can be easy to stay in your comfort zone and do what you know, but to really push yourself sometimes you need to try something new, it is a matter of making that career transition as smooth as possible for yourself. The comment that was posted is here below (thanks Dean for the kind words they are appreciated). Hi David, I just wanted to let you know that I work for a company called Milestone Search in Melbourne, Victoria Australia. (www.mstone.com.au) We subscribe to your feed on a daily basis and find your blogs both interesting and insightful. Not to mention extremely entertaining. I wonder if you have missed out on getting in journalism as this seems to be something you'd be great at ?: ) Anyways back to my point about changing careers. This could be anything from going from I.T. to Journalism, Engineering to Teaching or any combination of career you can think of. I don't think there ever has been a time where we have had so many opportunities to do so many different things in our working life. While this idea sounds great in theory, putting it into practice would be much harder to do I think. First, in an increasingly competitive job market, employers tend to look for specialists in their field. You may want to make a change but your options may be limited by the number of employers willing to take a chance on someone new to an industry that will likely require a significant investment in time to get brought up to speed. Also, using myself as an example if I was given the opportunity to move into Journalism/Communication/Marketing career from my career as an IT Recruiter - realistically I would have to take a significant pay cut to make this change as my current salary reflects the expertise I have in my current career. I would not immediately be up to speed moving into a new career and would not be able to justify a similar salary. Yes there are transferable skills in any career change, but even though you may have transferable skills you must realise that you will also have a large amount of learning to do which would take time. These are two initial hurdles that I immediately think of, there may be more but nothing is insurmountable. If you work out what you want to do with your working career whatever that may be, you then need to just need to work out the steps to get to your end goal. This is where utilising the power of your networks and using Social Media can come in handy. If you are interested in working somewhere why not proactively take the opportunity to research the industry or company - find out who it is you need to speak to and get in touch with them. We spend so much time working, we should enjoy the work we do and not be afraid to try new things. Waiting for your dream job to fall into your lap or be handed to you on a silver platter is not likely going to happen, so if there is something you do want to do, work out a plan to make it happen and chase after it.

• OWB 11gR2 &ndash; OLAP and Simba

  - by David Allan

  Oracle Warehouse Builder was the first ETL product to provide a single integrated and complete environment for managing enterprise data warehouse solutions that also incorporate multi-dimensional schemas. The OWB 11gR2 release provides Oracle OLAP 11g deployment for multi-dimensional models (in addition to support for prior releases of OLAP). This means users can easily utilize Simba's MDX Provider for Oracle OLAP (see here for details and cost) which allows you to use the powerful and popular ad hoc query and analysis capabilities of Microsoft Excel PivotTables® and PivotCharts® with your Oracle OLAP business intelligence data. The extensions to the dimensional modeling capabilities have been built on established relational concepts, with the option to seamlessly move from a relational deployment model to a multi-dimensional model at the click of a button. This now means that ETL designers can logically model a complete data warehouse solution using one single tool and control the physical implementation of a logical model at deployment time. As a result data warehouse projects that need to provide a multi-dimensional model as part of the overall solution can be designed and implemented faster and more efficiently. Wizards for dimensions and cubes let you quickly build dimensional models and realize either relationally or as an Oracle database OLAP implementation, both 10g and 11g formats are supported based on a configuration option. The wizard provides a good first cut definition and the objects can be further refined in the editor. Both wizards let you choose the implementation, to deploy to OLAP in the database select MOLAP: multidimensional storage. You will then be asked what levels and attributes are to be defined, by default the wizard creates a level bases hierarchy, parent child hierarchies can be defined in the editor. Once the dimension or cube has been designed there are special mapping operators that make it easy to load data into the objects, below we load a constant value for the total level and the other levels from a source table.   Again when the cube is defined using the wizard we can edit the cube and define a number of analytic calculations by using the 'generate calculated measures' option on the measures panel. This lets you very easily add a lot of rich analytic measures to your cube. For example one of the measures is the percentage difference from a year ago which we can see in detail below. You can also add your own custom calculations to leverage the capabilities of the Oracle OLAP option, either by selecting existing template types such as moving averages to defining true custom expressions. The 11g OLAP option now supports percentage based summarization (the amount of data to precompute and store), this is available from the option 'cost based aggregation' in the cube's configuration. Ensure all measure-dimensions level based aggregation is switched off (on the cube-dimension panel) - previously level based aggregation was the only option. The 11g generated code now uses the new unified API as you see below, to generate the code, OWB needs a valid connection to a real schema, this was not needed before 11gR2 and is a new requirement since the OLAP API which OWB uses is not an offline one. Once all of the objects are deployed and the maps executed then we get to the fun stuff! How can we analyze the data? One option which is powerful and at many users' fingertips is using Microsoft Excel PivotTables® and PivotCharts®, which can be used with your Oracle OLAP business intelligence data by utilizing Simba's MDX Provider for Oracle OLAP (see Simba site for details of cost). I'll leave the exotic reporting illustrations to the experts (see Bud's demonstration here), but with Simba's MDX Provider for Oracle OLAP its very simple to easily access the analytics stored in the database (all built and loaded via the OWB 11gR2 release) and get the regular features of Excel at your fingertips such as using the conditional formatting features for example. That's a very quick run through of the OWB 11gR2 with respect to Oracle 11g OLAP integration and the reporting using Simba's MDX Provider for Oracle OLAP. Not a deep-dive in any way but a quick overview to illustrate the design capabilities and integrations possible.

• SWFObject and IE6 causing hair-pulling agony

  - by Piet

  I recently used SWFObject to display a flash header on a website. I chose SWFObject because: Instead of displaying an annoying ‘Install flash now’ message, it claims to be able to show alternate content. In this case: the original header image. It claims to be compatible with more or less every browser out there. Implementation went fine, until someone tested it on IE6 and got the following error: Internet explorer cannot open the Internet site http://www….. Operation aborted Which basically means that the site just can’t be visited with IE6 (still used a lot in business environments), it even seems as if there’s something wrong with your internet connection. Now, since about 10% of visitors to this site are still using IE6 (why does everyone still use Internet Explorer ???? Do YOU know that these days most people do NOT use Internet Explorer anymore ?) Now after some googling, I found the suggestion to defer loading of the SWFObject.js as follows: <script type="text/javascript" defer=”defer” src=”http://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js” </script> <script type=”text/javascript” defer=”defer” swfobject.registerObject(”myId”, “9″, “”); </script> What this does according to W3C: When set, this boolean attribute provides a hint to the user agent that the script is not going to generate any document content (e.g., no “document.write” in javascript) and thus, the user agent can continue parsing and rendering. I don’t know exactly why, but: HURRAY! It works now!!! Only… IE6 and IE7 (didn’t try IE8) now gave the following error: Line: 19 Char: 1 Error: ’swfobject’ is undefined Code: 0 URL: http://www… But the flash was still running fine. Still, such an error isn’t clean, especially since almost half of the site’s visitors are using one of these Internet Explorer versions. Now, wanting a quick fix I decided to do the following: <script type="text/javascript" defer="defer" if (typeof(swfobject) != "undefined") swfobject.registerObject("myId", "9", ""); </script> I admit this is a bit of a weird ‘fix’. You’d suspect the flash to stop working on IE6/IE7, which it doesn’t. Not planning on diving into it’s inner bowels, I regard this a ‘mission accomplished’ until someone somewhere posts a better solution (for which I setup some Google alerts). Do you have a better solution? What would be the impact on the webdev economy (or your life) if all browsers were compatible? Addendum Because the above turned out not to work with the new Firefox 3.5.3 (strangely, was OK with 3.5.2 when I tested it) I decided to cut the crap and use the ‘Dynamic Publishing’ way. Ok, so it won’t work for people who have javascript disabled, but who on earth would have flash installed AND javascript disabled? To avoid the IE6 error with the ‘Dynamic Publishing’ way, I call swfobject.embedSWF right after the div that will be replaced with the flash content. Calling swfobject.embedSWF in the <head> would otherwise give me the above error in IE6 again.

• From the Tips Box: Pre-installation Prep Work Makes Service Pack Upgrades Smoother

  - by Jason Fitzpatrick

  Last month Microsoft rolled out Windows 7 Service Pack 1 and, like many SP releases, quite a few people are hanging back to see what happens. If you want to update but still error on the side of caution, reader Ron Troy  offers a step-by-step guide. Ron’s cautious approach does an excellent job minimizing the number of issues that could crop up in a Service Pack upgrade by doing a thorough job updating your driver sets and clearing out old junk before you roll out the update. Read on to see how he does it: Just wanted to pass on a suggestion for people worried about installing Service Packs.  I came up with a ‘method’ a couple years back that seems to work well. Run Windows / Microsoft Update to get all updates EXCEPT the Service Pack. Use Secunia PSI to find any other updates you need. Use CCleaner or the Windows disk cleanup tools to get rid of all the old garbage out there.  Make sure that you include old system updates. Obviously, back up anything you really care about.  An image backup can be real nice to have if things go wrong. Download the correct SP version from Microsoft.com; do not use Windows / Microsoft Update to get it.  Make sure you have the 64 bit version if that’s what you have installed on your PC. Make sure that EVERYTHING that affects the OS is up to date.  That includes all sorts of drivers, starting with video and audio.  And if you have an Intel chipset, use the Intel Driver Utility to update those drivers.  It’s very quick and easy.  For the video and audio drivers, some can be updated by Intel, some by utilities on the vendor web sites, and some you just have to figure out yourself.  But don’t be lazy here; old drivers and Windows Service Packs are a poor mix. If you have 3rd party software, check to see if they have any updates for you.  They might not say that they are for the Service Pack but you cut your risk of things not working if you do this. Shut off the Antivirus software (especially if 3rd party). Reboot, hitting F8 to get the SafeMode menu.  Choose SafeMode with Networking. Log into the Administrator account to ensure that you have the right to install the SP. Run the SP.  It won’t be very fancy this way.  Maybe 45 minutes later it will reboot and then finish configuring itself, finally letting you log in. Total installation time on most of my PC’s was about 1 hour but that followed hours of preparation on each. On a separate note, I recently got on the Nvidia web site and their utility told me I had a new driver available for my GeForce 8600M GS.  This laptop had come with Vista, now has Win 7 SP1.  I had a big surprise from this driver update; the Windows Experience Score on the graphics side went way up.  Kudo’s to Nvidia for doing a driver update that actually helps day to day usage.  And unlike ATI’s updates (which I need for my AGP based system), this update was fairly quick and very easy.  Also, Nvidia drivers have never, as I can recall, given me BSOD’s, many of which I’ve gotten from ATI (TDR errors).How to Enable Google Chrome’s Secret Gold IconHTG Explains: What’s the Difference Between the Windows 7 HomeGroups and XP-style Networking?Internet Explorer 9 Released: Here’s What You Need To Know

• Hello World Pagelet

  - by astemkov

  Introduction The goal of this exercise is to give you a basic feel of how you can use Pagelet Producer to proxy a web page We will proxy a simple static Hello World web page, cut one section out of that page and present it as a pagelet that you can later insert on your own application page or to your portal page such as WebCenter Portal space or WebCenter Interaction community page. Hello World sample app This is the static web page we will work with: Let's assume the following: The Hello World web page is running on server http://appserver.company.com:1234/ The Hello World web page path is: http://appserver.company.com:1234/helloworld/ Initial Pagelet Producer setup Let's assume that the Pagelet Producer server is running on http://pageletserver.company.com:8889/pagelets/ First let's check that Pagelet Producer is up and running. In order to do that we just need to access the following URL: http://pageletserver.company.com:8889/pagelets/ And this is what should be returned: Now you can access Pagelet Producer administration screens using this URL: http://pageletserver.company.com:8889/pagelets/admin This is how the UI looks: Now if you connect to the internet via proxy server, you need to configure proxy in Pagelet Producer settings. In the Navigator pane: Jump To - Settings Click on "Proxy" Enter your proxy server configuration: Creating a resource First thing that you need to do is to create a resource for your web page. This will tell Pagelet Producer that all sub-paths of the web page should be proxied. It also will allow you to setup common rules of how your web page should be proxied and will serve as a container for your pagelets. In the Navigator pane: Jump To - Resources Click on any existing resource (ex. welcome_resource) Click on "Create selected type" toolbar button at the top of the Navigator pane Select "Web" in the "Select Producer Type" dialog box and click "OK" Now after the resource is created let's click on "General" sub-item a specify the following values Name = AppServer Source URL = http://appserver.company.com:1234/ Destination URL = /appserver/ Click on "Save" toolbar button at the top of the Navigator pane After the resource is created our web page becomes accessible by the URL: http://pageletserver.company.com:8889/pagelets/appserver/helloworld/ So in original web page address Source URL is replaced with Pagelet Producer URL (http://pageletserver.company.com:8889/pagelets) + Destination URL Creating a pagelet Now let's create "Hello World" pagelet. Under the resource node activate Pagelets subnode Click on "Create selected type" toolbar button at the top of the Navigator pane Click on "General" sub-node of newly created pagelet and specify the following values Name = Hello_World Library = MyLib Library is used for logical grouping. The portals use the "Library" value to group pagelets in their respective UI's. For example, when adding pagelets to a WebCenter Portal space you would see the individual pagelets listed under the "Library" name. URL Suffix = helloworld/index.html this is where the Hello World page html is served from Click on "Save" toolbar button at the top of the Navigator pane The Library name can be anything you want, it doesn't have to match the resource name at all. It is used as a logical grouping of pagelets, and you can include pagelets from multiple resources into the same library or create a new library for each pagelet. After you save the pagelet you can access it here: http://pageletserver.company.com:8889/pagelets/inject/v2/pagelet/MyLib/Hello_World which is : http://pageletserver.company.com:8889/pagelets/inject/v2/pagelet/ + [Library] + [Name] Or to test the injection of a pagelet into iframe you can click on the pagelets "Documentation" sub-node and use "Access Pagelet using REST" URL: This is what we will see: Clipping The pagelet that we just created covers the whole web page, but we want just the "Hello World" segment of it. So let's clip it. Under the Hello_World pagelet node activate Clipper sub-node Click on "Create selected type" toolbar button at the top of the Navigator pane Specify a Name for newly created clipper. For example: "c1" Click on "Content" sub-node of the clipper Click on "Launch Clipper" button New browser window will open By moving a mouse pointer over the web page select the area you want to clip: Click left mouse button - the browser window will disappear and you will see that Clipping Path was automatically generated Now let's save and access the link from the "Documentation" page again Here's our pagelet nicely clipped and ready for being used on your Web Center Space

• Tough Decisions

  - by Johnm

  There was once a thriving business that employed two Database Administrators, Sam and Jim. Both DBAs were certified, educated and highly talented in their skill sets. During lunch breaks these two DBAs were often found together discussing best practices, troubleshooting techniques and the latest release notes for the upcoming version of SQL Server. They genuinely loved what they did. The maintenance of the first database was the responsibility of Sam. He was the architect of this server's setup and he was very meticulous in its configuration. He regularly monitored the health of the database, validated backup files and regularly adhered to the best practices that were advocated by well respected professionals. He was very proud of the fact that there was never a database that he managed that lost data or performed poorly. The maintenance of the second database was the responsibility of Jim. He too was the architect of this server's setup. At the time that he built this server, his understanding of the finer details of configuration were not as clear as they are today. The server was build on a shoestring budget and with very little time for testing and implementation. Jim often monitored the health of the database; but in more of a reactionary mode due to user complaints of slowness or failed transactions. Deadlocks abounded and the backup files were never validated. One day, the announcement was made that revealed that the business had hit financially hard times. Budgets were being cut, limitation on spending was implemented and the reduction in full-time staff was required. Since having two DBAs was regarded a luxury by many, this meant that either Sam or Jim were about to find themselves out of a job. Sam and Jim's boss, Frank, was faced with a very tough decision. Sam's performance was flawless. His techniques and practices were perfection. The databases he managed were reliable and efficient. His solutions are "by the book". When given a task it is certain that, while it may take a little longer, it will be done right the first time. Jim's techniques and practices were not perfect; but effective and responsive. He made mistakes regularly; but he shows that he learns from them and they often result in innovative solutions. When given a task it is certain that, while the results may require some tweaking, it will be done on time and under budget. You are Frank's best friend. He approaches you and presents this scenario. He must layoff one of his valued DBAs the very next morning. Frank asks you: "All else being equal, who would you let go? and Why?" Another pertinent question is raised: "Regardless of good times or bad, if you had to choose, which DBA would you want on your team when tough challenges arise?" Your response is. (This is where you enter a comment below)

• How do I fix my resolution after Directx install through Steam?

  I'm a bit long-winded so see bottom for quick version and specs. Friendly Hello: Hello all on these askUbuntu pages, I just recently built my own computer and decided to switch to Ubuntu for the extra coolness. I've been learning a lot through all this, and mostly been trying to figure out issues on my own (read: Google searches). However, I couldn't seem to find others with this problem so I've come here for help. Detailed Recount: So I just used WINE and WINETRICKS to install Steam. All went well and it worked. Then I went to trying a game out. I remembered that Orcs Must Die! worked from http://www.steamgamesonlinux.com/ so I tried that out. After selecting to download it, that's when the problem occurred. The screen suddenly zoomed in!!! I think it's the resolution right? Half the screen is cut off and I can't see parts of the right side of windows. My theory is that this is due to Direct X being installed through Steam, as Steam automatically installed it as I chose to download the game. It didn't even ask me to install Direct X or not ): It all happened so fast. This all being said, the game works fine! It looks a little strange, as if the resolution was off, but it plays just fine. What I did so far: Restarted my computer. Didn't work -_- Researched Steam installing DirectX on Ubuntu then messing up resolution and couldn't really find anything. Researched uninstalling DirectX from Ubuntu but only found uninstalling DirectX after having been installed with Wine, not through Steam. Got mad and ate my feelings. Tried "xrandr -s 0" but it didn't do anything. Ran xrandr alone and terminal showed this: Screen 0: minimum 8 x 8, current 640 x 480, maximum 16384 x 16384 DVI-I-0 connected 640x480+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 640x480 59.9*+ 320x240 120.1 DVI-I-1 disconnected (normal left inverted right x axis y axis) HDMI-0 disconnected (normal left inverted right x axis y axis) DP-0 disconnected (normal left inverted right x axis y axis) DVI-D-0 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) About now I was mad so I played Odin's Sphere then took a nap. Back to it! I entered the following: xrandr --output DVI-I-0 --mode 1024x768 But I was met with this message: xrandr: cannot find mode 1024x768 I get the same messages for 800x600, 1400x1050, and seemingly any other combination of numbers. I then tried Going into System Settings then Displays, then playing around in there. My Resolution is set to 640x480 and there are no other options for me to choose from. Rotation has Normal, Clockwise, Counter Clockwise, and 180 Degrees. It's set to Normal and I haven't messed with that. Launcher Placement has Unknown and All Displays as its two options. It's set to Unknown, but moving it to All Displays doesn't seem to do anything. Finally, when I click Detect Displays, nothing seems to happen. Quick Version: Linux noob. Steam installed with Wine and Winetricks. Steam downloaded and installed game + DirectX. Resolution messed up now (I think; pretty sure), can't fix it, very annoying, no idea what's going on, halp! Specs: Ubuntu Version 12.04 Wine Version 1.4.1 Have not changed any settings in Wine Using Winetricks Graphics Card: http://www.gigabyte.com/products/pro...px?pid=4361#sp Drivers: Proprietary (Installing those were a LOT of fun) Also let it be known that I have a DVI to VGA cord running from my Graphics card to my monitor. If any more information is needed I am ready to report. Thank You: Thanks a lot for your help and all the work you do to support noob ubuntuers like me (:
