  • Is there an off the shelf CMS that can be used as a back end for smartphone travel guide apps?

    - by eamonncarey
    I'm wondering if there's an off the shelf CMS available that is similar to something like Mobile Roadie - ie: it will allow you to create multiple versions of one application? I'm looking to develop some mobile travel guides for iPhone/Android/Blackberry etc, and rather than get a CMS built, I'd like to see if there's something out there is similar to Wordpress in that it will allow us to input text, images, Google Maps details, phone numbers, email addresses and potentially some audio/video content. If anyone knows of anything, I'd love to hear about it. Also, if you have any ideas regarding pricing, that would be extremely helpful! Thanks in advance for your assistance.

  • Beginner's Language app

    - by Eiseldora
    Hi I'm a techie with no programing experience. I know html and css, but I'd like to someday be able to make an app for my phone (I have an android) and possibly mobile websites. I made learning a programing language and creating a mobile app a goal for my job, and now my boss would like me to pick a programing language to learn. I found a free open course from MIT (http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-00-introduction-to-computer-science-and-programming-fall-2008/) called introduction to computer science. In the course they teach python, but more importantly it seems they teach how to think like a programmer. When I told my boss about the free online course she didn't think that Python was an appropriate language for me to learn. She'd like me to learn a language that is more similar to one used to make Phone apps. Does anyone out there know a better language for me to pick up that would be similar to Android or iPhone's App language. Thank you

  • partial string matching - R

    - by DonDyck
    I need to write a query in R to match partial string in column names. I am looking for something similar to LIKE operator in SQL. For e.g, if I know beginning, middle or end part of the string I would write the query in format: LIKE 'beginning%middle%' in SQL and it would return matching strings. In pmatch or grep it seems I can only specify 'beginning' , 'end' and not the order. Is there any similar function in R that I am looking for? For example, say I am looking in the vector: y<- c("I am looking for a dog", "looking for a new dog", "a dog", "I am just looking") Lets say I want to write a query which picks "looking for a new dog" and I know start of the string is "looking" and end of string is "dog". If I do a grep("dog",y) it will return 1,2,3. Is there any way I can specify beginning and end in grep?

  • Linux software RAID6: rebuild slow

    - by Ole Tange
    I am trying to find the bottleneck in the rebuilding of a software raid6. ## Pause rebuilding when measuring raw I/O performance # echo 1 > /proc/sys/dev/raid/speed_limit_min # echo 1 > /proc/sys/dev/raid/speed_limit_max ## Drop caches so that does not interfere with measuring # sync ; echo 3 | tee /proc/sys/vm/drop_caches >/dev/null # time parallel -j0 "dd if=/dev/{} bs=256k count=4000 | cat >/dev/null" ::: sdbd sdbc sdbf sdbm sdbl sdbk sdbe sdbj sdbh sdbg 4000+0 records in 4000+0 records out 1048576000 bytes (1.0 GB) copied, 7.30336 s, 144 MB/s [... similar for each disk ...] # time parallel -j0 "dd if=/dev/{} skip=15000000 bs=256k count=4000 | cat >/dev/null" ::: sdbd sdbc sdbf sdbm sdbl sdbk sdbe sdbj sdbh sdbg 4000+0 records in 4000+0 records out 1048576000 bytes (1.0 GB) copied, 12.7991 s, 81.9 MB/s [... similar for each disk ...] So we can read sequentially at 140 MB/s in the outer tracks and 82 MB/s in the inner tracks on all the drives simultaneously. Sequential write performance is similar. This would lead me to expect a rebuild speed of 82 MB/s or more. # echo 800000 > /proc/sys/dev/raid/speed_limit_min # echo 800000 > /proc/sys/dev/raid/speed_limit_max # cat /proc/mdstat md2 : active raid6 sdbd[10](S) sdbc[9] sdbf[0] sdbm[8] sdbl[7] sdbk[6] sdbe[11] sdbj[4] sdbi[3](F) sdbh[2] sdbg[1] 27349121408 blocks super 1.2 level 6, 128k chunk, algorithm 2 [9/8] [UUU_UUUUU] [=========>...........] recovery = 47.3% (1849905884/3907017344) finish=855.9min speed=40054K/sec But we only get 40 MB/s.

This fits with the hypothesis that the max is around 80 MB/s. Since this is software raid the limiting factor could be CPU. top says: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 38520 root 20 0 0 0 0 R 64 0.0 2947:50 md2_raid6 6117 root 20 0 0 0 0 D 53 0.0 473:25.96 md2_resync So md2_raid6 and md2_resync are clearly busy taking up 64% and 53% of a CPU respectively, but not near 100%. The chunk size (128k) of the RAID was chosen after measuring which chunksize gave the least CPU penalty. If this speed is normal: What is the limiting factor? Can I measure that? If this speed is not normal: How can I find the limiting factor? Can I change that?

  • Developer Developer Developer Scotland 2010

    - by Chris Hardy (ChrisNTR)
    This past weekend, I headed up to Glasgow thanks to Plip for driving and Dave Sussman for some light entertainment to do a session on C# on the iPhone with MonoTouch. I had already presented a session similar to this one at DDD8 in Reading, which you can watch on Vimeo ( http://vimeo.com/9150434 ) but in this session I covered more topics such as the new 3.3.1 section of the new terms of service Apple released. I also showed a Twitter example written in MonoTouch, which was reused from the DDD8 session...(read more)

  • protect purchased games to be downloaded on other pc

    - by JoJo
    I want to make a downloads managing system on my website, that when you purchase a download, you can always re-download it again for free. (i have read that Steam does something similar) The problem is, that someone would be able to create a account, purchase something and then give the account password to friends and family, so they can all download copies for free. Is there a way to prevent this? Or is it impossible.

  • SQL SERVER – Copy Data from One Table to Another Table – SQL in Sixty Seconds #031 – Video

    - by pinaldave
    Copy data from one table to another table is one of the most requested questions on forums, Facebook and Twitter. The question has come in many formats and there are places I have seen developers are using cursor instead of this direct method. Earlier I have written the similar article a few years ago - SQL SERVER – Insert Data From One Table to Another Table – INSERT INTO SELECT – SELECT INTO TABLE. The article has been very popular and I have received many interesting and constructive comments. However there were two specific comments keep on ending up on my mailbox. 1) SQL Server AdventureWorks Samples Database does not have table I used in the example 2) If there is a video tutorial of the same example. After carefully thinking I decided to build a new set of the scripts for the example which are very similar to the old one as well video tutorial of the same. There was no better place than our SQL in Sixty Second Series to cover this interesting small concept. Let me know what you think of this video. Here is the updated script. -- Method 1 : INSERT INTO SELECT USE AdventureWorks2012 GO ----Create TestTable CREATE TABLE TestTable (FirstName VARCHAR(100), LastName VARCHAR(100)) ----INSERT INTO TestTable using SELECT INSERT INTO TestTable (FirstName, LastName) SELECT FirstName, LastName FROM Person.Person WHERE EmailPromotion = 2 ----Verify that Data in TestTable SELECT FirstName, LastName FROM TestTable ----Clean Up Database DROP TABLE TestTable GO --------------------------------------------------------- --------------------------------------------------------- -- Method 2 : SELECT INTO USE AdventureWorks2012 GO ----Create new table and insert into table using SELECT INSERT SELECT FirstName, LastName INTO TestTable FROM Person.Person WHERE EmailPromotion = 2 ----Verify that Data in TestTable SELECT FirstName, LastName FROM TestTable ----Clean Up Database DROP TABLE TestTable GO Related Tips in SQL in Sixty Seconds: SQL SERVER – Insert Data From One Table to Another Table – INSERT INTO SELECT – SELECT INTO TABLE Powershell – Importing CSV File Into Database – Video SQL SERVER – 2005 – Export Data From SQL Server 2005 to Microsoft Excel Datasheet SQL SERVER – Import CSV File into Database Table Using SSIS SQL SERVER – Import CSV File Into SQL Server Using Bulk Insert – Load Comma Delimited File Into SQL Server SQL SERVER – 2005 – Generate Script with Data from Database – Database Publishing Wizard What would you like to see in the next SQL in Sixty Seconds video?

  • How I use PowerShell to collect Performance Counter data

    - by AaronBertrand
    In a current project, I need to collect performance counters from a set of virtual machines that are performing different tasks and running a variety of workloads. In a similar project last year, I used LogMan to collect performance data. This time I decided to try PowerShell because, well, all the kids are doing it, I felt a little passé, and a lot of the other tasks in this project (such as building out VMs and running workloads) were already being accomplished via PowerShell. And after all, I...(read more)

  • Racing MMO for Linux - 2D or 3D - Massively Multiplayer Online Racing Games for Linux

    - by Paulocoghi
    I really like multiplayer racing games, like Need for Speed World or similar. I wonder if there is any MMO racing game for Linux (2D or 3D). Browser-based games are also accepted. Note: I tried this question in the Gaming Q&A of StackExchange (see link below), but one user said that my question was off-topic. http://gaming.stackexchange.com/questions/16329/racing-mmo-for-linux-2d-or-3d-massively-multiplayer-online-racing-games

  • Setting up a local AI server - easy with Solaris 11

    - by Stefan Hinker
    Many things are new in Solaris 11, Autoinstall is one of them.  If, like me, you've known Jumpstart for the last 2 centuries or so, you'll have to start from scratch.  Well, almost, as the concepts are similar, and it's not all that difficult.  Just new. I wanted to have an AI server that I could use for demo purposes, on the train if need be.  That answers the question of hardware requirements: portable.  But let's start at the beginning. First, you need an OS image, of course.  In the new world of Solaris 11, it is now called a repository.  The original can be downloaded from the Solaris 11 page at Oracle.   What you want is the "Oracle Solaris 11 11/11 Repository Image", which comes in two parts that can be combined using cat.  MD5 checksums for these (and all other downloads from that page) are available closer to the top of the page. With that, building the repository is quick and simple: # zfs create -o mountpoint=/export/repo rpool/ai/repo # zfs create rpool/ai/repo/s11 # mount -o ro -F hsfs /tmp/sol-11-1111-repo-full.iso /mnt # rsync -aP /mnt/repo /export/repo/s11 # umount /mnt # pkgrepo rebuild -s /export/repo/sol11/repo # zfs snapshot rpool/ai/repo/sol11@fcs # pkgrepo info -s /export/repo/sol11/repo PUBLISHER PACKAGES STATUS UPDATED solaris 4292 online 2012-03-12T20:47:15.378639Z That's all there's to it.  Let's make a snapshot, just to be on the safe side.  You never know when one will come in handy.  To use this repository, you could just add it as a file-based publisher: # pkg set-publisher -g file:///export/repo/sol11/repo solaris In case I'd want to access this repository through a (virtual) network, i'll now quickly activate the repository-service: # svccfg -s application/pkg/server \ setprop pkg/inst_root=/export/repo/sol11/repo # svccfg -s application/pkg/server setprop pkg/readonly=true # svcadm refresh application/pkg/server # svcadm enable application/pkg/server That's all you need - now point your browser to http://localhost/ to view your beautiful repository-server. Step 1 is done.  All of this, by the way, is nicely documented in the README file that's contained in the repository image. Of course, we already have updates to the original release.  You can find them in MOS in the Oracle Solaris 11 Support Repository Updates (SRU) Index.  You can simply add these to your existing repository or create separate repositories for each SRU.  The individual SRUs are self-sufficient and incremental - SRU4 includes all updates from SRU2 and SRU3.  With ZFS, you can also get both: A full repository with all updates and at the same time incremental ones up to each of the updates: # mount -o ro -F hsfs /tmp/sol-11-1111-sru4-05-incr-repo.iso /mnt # pkgrecv -s /mnt/repo -d /export/repo/sol11/repo '*' # umount /mnt # pkgrepo rebuild -s /export/repo/sol11/repo # zfs snapshot rpool/ai/repo/sol11@sru4 # zfs set snapdir=visible rpool/ai/repo/sol11 # svcadm restart svc:/application/pkg/server:default The normal repository is now updated to SRU4.  Thanks to the ZFS snapshots, there is also a valid repository of Solaris 11 11/11 without the update located at /export/repo/sol11/.zfs/snapshot/fcs . If you like, you can also create another repository service for each update, running on a separate port. But now lets continue with the AI server.  Just a little bit of reading in the dokumentation makes it clear that we will need to run a DHCP server for this.  Since I already have one active (for my SunRay installation) and since it's a good idea to have these kinds of services separate anyway, I decided to create this in a Zone.  So, let's create one first: # zfs create -o mountpoint=/export/install rpool/ai/install # zfs create -o mountpoint=/zones rpool/zones # zonecfg -z ai-server zonecfg:ai-server> create create: Using system default template 'SYSdefault' zonecfg:ai-server> set zonepath=/zones/ai-server zonecfg:ai-server> add dataset zonecfg:ai-server:dataset> set name=rpool/ai/install zonecfg:ai-server:dataset> set alias=install zonecfg:ai-server:dataset> end zonecfg:ai-server> commit zonecfg:ai-server> exit # zoneadm -z ai-server install # zoneadm -z ai-server boot ; zlogin -C ai-server Give it a hostname and IP address at first boot, and there's the Zone.  For a publisher for Solaris packages, it will be bound to the "System Publisher" from the Global Zone.  The /export/install filesystem, of course, is intended to be used by the AI server.  Let's configure it now: #zlogin ai-server root@ai-server:~# pkg install install/installadm root@ai-server:~# installadm create-service -n x86-fcs -a i386 \ -s pkg://solaris/install-image/[email protected],5.11-0.175.0.0.0.2.1482 \ -d /export/install/fcs -i 192.168.2.20 -c 3 With that, the core AI server is already done.  What happened here?  First, I installed the AI server software.  IPS makes that nice and easy.  If necessary, it'll also pull in the required DHCP-Server and anything else that might be missing.  Watch out for that DHCP server software.  In Solaris 11, there are two different versions.  There's the one you might know from Solaris 10 and earlier, and then there's a new one from ISC.  The latter is the one we need for AI.  The SMF service names of both are very similar.  The "old" one is "svc:/network/dhcp-server:default". The ISC-server comes with several SMF-services. We at least need "svc:/network/dhcp/server:ipv4".  The command "installadm create-service" creates the installation-service. It's called "x86-fcs", serves the "i386" architecture and gets its boot image from the repository of the system publisher, using version 5.11,5.11-0.175.0.0.0.2.1482, which is Solaris 11 11/11.  (The option "-a i386" in this example is optional, since the installserver itself runs on a x86 machine.) The boot-environment for clients is created in /export/install/fcs and the DHCP-server is configured for 3 IP-addresses starting at 192.168.2.20.  This configuration is stored in a very human readable form in /etc/inet/dhcpd4.conf.  An AI-service for SPARC systems could be created in the very same way, using "-a sparc" as the architecture option. Now we would be ready to register and install the first client.  It would be installed with the default "solaris-large-server" using the publisher "http://pkg.oracle.com/solaris/release" and would query it's configuration interactively at first boot.  This makes it very clear that an AI-server is really only a boot-server.  The true source of packets to install can be different.  Since I don't like these defaults for my demo setup, I did some extra config work for my clients. The configuration of a client is controlled by manifests and profiles.  The manifest controls which packets are installed and how the filesystems are layed out.  In that, it's very much like the old "rules.ok" file in Jumpstart.  Profiles contain additional configuration like root passwords, primary user account, IP addresses, keyboard layout etc.  Hence, profiles are very similar to the old sysid.cfg file. The easiest way to get your hands on a manifest is to ask the AI server we just created to give us it's default one.  Then modify that to our liking and give it back to the installserver to use: root@ai-server:~# mkdir -p /export/install/configs/manifests root@ai-server:~# cd /export/install/configs/manifests root@ai-server:~# installadm export -n x86-fcs -m orig_default \ -o orig_default.xml root@ai-server:~# cp orig_default.xml s11-fcs.small.local.xml root@ai-server:~# vi s11-fcs.small.local.xml root@ai-server:~# more s11-fcs.small.local.xml <!DOCTYPE auto_install SYSTEM "file:///usr/share/install/ai.dtd.1"> <auto_install> <ai_instance name="S11 Small fcs local"> <target> <logical> <zpool name="rpool" is_root="true"> <filesystem name="export" mountpoint="/export"/> <filesystem name="export/home"/> <be name="solaris"/> </zpool> </logical> </target> <software type="IPS"> <destination> <image> <!-- Specify locales to install --> <facet set="false">facet.locale.*</facet> <facet set="true">facet.locale.de</facet> <facet set="true">facet.locale.de_DE</facet> <facet set="true">facet.locale.en</facet> <facet set="true">facet.locale.en_US</facet> </image> </destination> <source> <publisher name="solaris"> <origin name="http://192.168.2.12/"/> </publisher> </source> <!-- By default the latest build available, in the specified IPS repository, is installed.

Use my own package service as publisher, running on IP address 192.168.2.12 Install the initial release of Solaris 11:  pkg:/[email protected],5.11-0.175.0.0.0.2.0 Using a similar approach, I'll create a default profile interactively and use it as a template for a few customized building blocks, each defining a part of the overall system configuration.  The modular approach makes it easy to configure numerous clients later on: root@ai-server:~# mkdir -p /export/install/configs/profiles root@ai-server:~# cd /export/install/configs/profiles root@ai-server:~# sysconfig create-profile -o

192.168.2.100 user.xml None Here's the idea behind these files: "general.xml" contains settings valid for all my clients.  Stuff like DNS servers, for example, which in my case will always be the same. "user.xml" only contains user definitions.  That is, a root password and a primary user.Both of these profiles will be valid for all clients (for now). "mars.xml" defines network settings for an individual client.  This profile is associated with an IP-Address.  For this to work, I'll have to tweak the DHCP-settings in the next step: root@ai-server:~# installadm create-client -e 08:00:27:AA:3D:B1 -n x86-fcs root@ai-server:~# vi /etc/inet/dhcpd4.conf root@ai-server:~# tail -5 /etc/inet/dhcpd4.conf host 080027AA3DB1 { hardware ethernet 08:00:27:AA:3D:B1; fixed-address 192.168.2.100; filename "01080027AA3DB1"; } This completes the client preparations.  I manually added the IP-Address for mars to /etc/inet/dhcpd4.conf.  This is needed for the "mars.xml" profile.  Disabling arbitrary DHCP-replies will shut up this DHCP server, making my life in a shared environment a lot more peaceful ;-)Now, I of course want this installation to be completely hands-off.  For this to work, I'll need to modify the grub boot menu for this client slightly.  You can find it in /etc/netboot.  "installadm create-client" will create a new boot menu for every client, identified by the client's MAC address.  The template for this can be found in a subdirectory with the name of the install service, /etc/netboot/x86-fcs in our case.  If you don't want to change this manually for every client, modify that template to your liking instead. root@ai-server:~# cd /etc/netboot root@ai-server:~# cp menu.lst.01080027AA3DB1 menu.lst.01080027AA3DB1.org root@ai-server:~# vi menu.lst.01080027AA3DB1 root@ai-server:~# diff menu.lst.01080027AA3DB1 menu.lst.01080027AA3DB1.org 1,2c1,2 < default=1 < timeout=10 --- > default=0 > timeout=30 root@ai-server:~# more menu.lst.01080027AA3DB1 default=1 timeout=10 min_mem64=0 title Oracle Solaris 11 11/11 Text Installer and command line kernel$ /x86-fcs/platform/i86pc/kernel/$ISADIR/unix -B install_media=htt p://$serverIP:5555//export/install/fcs,install_service=x86-fcs,install_svc_addre ss=$serverIP:5555 module$ /x86-fcs/platform/i86pc/$ISADIR/boot_archive title Oracle Solaris 11 11/11 Automated Install kernel$ /x86-fcs/platform/i86pc/kernel/$ISADIR/unix -B install=true,inst all_media=http://$serverIP:5555//export/install/fcs,install_service=x86-fcs,inst all_svc_address=$serverIP:5555,livemode=text module$ /x86-fcs/platform/i86pc/$ISADIR/boot_archive Now just boot the client off the network using PXE-boot.  For my demo purposes, that's a client from VirtualBox, of course.  That's all there's to it.  And despite the fact that this blog entry is a little longer - that wasn't that hard now, was it?

  • Friday Fun: Play Tetris in Google Chrome

    - by Asian Angel
    Do you prefer playing classic games rather than the newer ones? Then get ready for some classic goodness with the JC-Tetris extension for Google Chrome. JC-Tetris in Action When you click on your new “JC-Tetris Toolbar Button” a new mini-Chrome window will open with the game displayed inside. This could be very convenient for those who would like or need to pause the game, minimize the window, and finish the game later. All that is needed to play are the four “Arrow Keys & the Space Bar”. Note: The text was small when the window first opened during our test so we used the “Ctrl +” keyboard shortcut twice to enlarge it. You may or may not experience similar text size results. Like any Tetris game things start out “quietly enough” but this one speeds up quickly, so be prepared! Notice that you do get a warning of what is waiting to drop onto the game board on the left side. Whenever you complete a game you will see this small window asking if you would like to enter a name for the score…you can easily ignore/bypass the window by clicking “Cancel”. Another game and a much better result. Do not be surprised if you feel that little burst of “rushed panic” at the end! Conclusion JC-Tetris is an enjoyable way to relax when you need a break. The ability to pause the game and minimize it for later makes it even better. Have fun!

  • SQL SERVER – Fix Error: Microsoft OLE DB Provider for SQL Server error ’80040e07' or Microsoft SQL Native Client error ’80040e07'

    - by pinaldave
    I quite often receive questions where users are looking for solution to following error: Microsoft OLE DB Provider for SQL Server error ’80040e07′ Syntax error converting datetime from character string. OR Microsoft SQL Native Client error ’80040e07′ Syntax error converting datetime from character string. If you have ever faced above error – I have a very simple solution for you. The solution is being very check date which is inserted in the datetime column. This error often comes up when application or user is attempting to enter an incorrect date into the datetime field. Here is one of the examples – one of the reader was using classing ASP Application with OLE DB provider for SQL Server. When he tried to insert following script he faced above mentioned error. INSERT INTO TestTable (ID, MyDate) VALUES (1, '01-Septeber-2013') The reason for the error was simple as he had misspelled September word. Upon correction of the word, he was able to successfully insert the value and error was not there. Incorrect values or the typo’s are not the only reason for this error. There can be issues with cast or convert as well. If you try to attempt following code using SQL Native Client or in your application you will also get similar errors. SELECT CONVERT (datetime, '01-Septeber-2013', 112) The reason here is very simple, any conversion attempt or any other kind of operation on incorrect date/time string can lead to the above error. If you not using embeded dynamic code in your application language but using attempting similar operation on incorrect datetime string you will get following error. Msg 241, Level 16, State 1, Line 2 Conversion failed when converting date and/or time from character string. Remember: Check your values of the string when you are attempting to convert them to string – either there can be incorrect values or they may be incorrectly formatted.

  • The Partner Perspective from Oracle OpenWorld 2012 - IDC’s Darren Bibby report

    - by Richard Lefebvre
    Below is IDC’s Darren Bibby report on ‘The Partner Perspective from Oracle OpenWorld 2012’. If you missed the 2012 edition, I trust this will give you the willingness to attend next year one! October 26, 2012 I attended my fourth Oracle OpenWorld earlier in October. I always go in with the lens of, "What's in it for partners this year?" Although it's primarily thought of as a customer event - and yes, the bulk of the almost 50,000 attendees are customers - this year's conference was clearly the largest and most important partner event Oracle has ever run. Oracle PartnerNetwork (OPN) Exchange There were more partner attendees than ever, with Oracle citing somewhere around 5000. But the format for partners this year was different. And it was better. Traditionally, Oracle hosts a one-day only Partner Forum on the Sunday before the customer-focused conference begins. This year, the partner content still began on the Sunday, but the worldwide alliances and channels group created an exclusive track throughout the week, just for partners. It featured content specifically targeted towards partners, and was anchored at a nearby hotel. This was a great move for Oracle. The Oracle PartnerNetwork (OPN) team has been in a tricky position for years in that they have enough partners that they need a landmark event in the year, but perhaps not enough to justify a separate, worldwide, large, partner-only event. Coinciding a four day event with Oracle OpenWorld, where anybody who's anybody in the Oracle world attends anyway, is a good solution. The channels leadership team can build from this success for an even better conference next year. It's expected that they will follow a similar strategy. Cloud Announcements for Partners As for the content, it was primarily about the Cloud. For customers, for VARs, for ISVs, for everyone. There were five key Cloud related announcements for partners at the event: Cloud Builder Specialization. This is one of the first broader Specializations that isn't focused on one unique product. It is a designation for partners that offer design and implementation services for private cloud solutions. As such, it will surely be something that nearly every partner will consider, and many will pursue. New Specializations for Cloud Services. Unlike the broad, almost "strategy-level" Specialization above, there are a group of new product-based "merit badges" for many of the new Cloud offerings. Think about a Specialization for the Cloud version of HCM, for instance. Each of these particular specializations will also have Rapid Start implementation methodologies that allow a partner to offer a fixed scope and fixed price bid to customers. Based on the learnings from Oracle Consulting, this means a partner might be able to deliver Cloud HCM in six weeks for a fixed price. In the end, this means more consistent experiences for Oracle customers. Cloud Resale Program. For those partners who achieve one of these Cloud Specializations, it will mean they can actually resell the subscription-based Cloud product. This is important because it has been somewhat of a rarity in the emerging Cloud channel for partners to be able to "take the paper", take the revenue, do the billing, be first line of support etc. This is an important step for Oracle and one the partners will be happy to see. Cloud Referral Program. For those partners who are not as engaged with these specific Cloud products that the Specializations revolve around, there is a new referral program that provides an incentive to recommend Oracle Cloud products. This one-two punch of referral and resale programs is similar in many ways to other vendors who allow more committed partners to resell, while more casual partners can collect fees. It's the model that seems to work. The key to allow a company to resell a subscription product - something that is inherently delivered directly between the vendor and customer - is trust. Achieving a specialization is a good bar to have to meet. Platform as a Service for ISVs. Leveraging some of the overall announcements made by CEO Larry Ellison around a cloud version of its famous database, Oracle also outlined a new ability for ISVs to build cloud services on its new PaaS offering. Details were less available for this announcement, though it's an expected and fitting play for ISVs comfortable with Oracle technology who can now more easily build out cloud applications. There wasn't much talk of an app store to go along with this, but surely it's in the works. Specializations And "The Gap" Coming back to Specializations, Oracle PartnerNetwork (OPN) has 4600 partners worldwide that hold 20,000 Specializations. These are impressive numbers just three years into the new OPN framework. The actual number of Specializations has also grown significantly, up to 111 today and soon around 125 or so with the new Cloud designations. Oracle may need to look at grouping some of these and creating higher level, broader designations that partners could achieve by earning several Specializations in that group. At 125 and growing, this is a lot. On the top of the pyramid, Hitachi Ltd. successfully became the eleventh partner to make it to the highly prestigious Diamond level. Partner programs partially exist in order to recognize capable partners. And it's more than abundantly clear that the Diamond level does this. But I think Oracle has a gap. Specializations show capability in a very specific product area, and all sizes of partners can achieve these. The next level at which to show a level of expertise is the Advanced Specialization. However, this is a massive step up from the regular Specialization. The advanced level requires 50 people to have certification in that particular product area. Most other industry programs have similar higher level statuses, but none are even close to that number. Whereas a customer who sees an Oracle partner with an advanced specialization can be very sure of capability, there is a gap in that there are hundreds or even thousands of 20-50 person solution providers who are top notch in their area of expertise. They will never get to Advanced due to numbers alone. These boutique partners don't really have a way of showing off their talents in the current program. Advanced may not need to be so high to really show that a company has deep expertise. Overall it was a very successful Oracle OpenWorld for Oracle partners of all sizes. There was progress made on making it a bigger and more relevant event. And also on catching up and maybe even leading in some cases with cloud opportunities for partners.

  • Looking for Your Next Challenge...Don't Stretch Too Far

    - by david.talamelli
    In my role as a Recruiter at Oracle I receive a large number of resumes of people who are interested in working with us. People contact me for a number of reasons, it can be about a specific role that we may be hiring for or they may send me an email asking if there are any suitable roles for them. Sometimes when I speak to people we have similar roles available to the roles that they may actually be in now. Sometimes people are interested in making this type of sideways move if their motivation to change jobs is not necessarily that they are looking for increased responsibility or career advancement (example: money, redundancy, work environment). However there are times when after walking through a specific role with a candidate that they may say to me - "You know that is very similar to the role that I am doing now. I would not want to move unless my next role presents me with the next challenge in my career". This is a far statement - if a person is looking to change jobs for the next step in their career they should be looking at suitable opportunities that will address their need. In this instance a sideways step will not really present any new challenges or responsibilities. The main change would be the company they are working for. Candidates looking for a new role because they are looking to move up the ladder should be looking for a role that offers them the next level of responsibility. I think the best job changes for people who are looking for career advancement are the roles that stretch someone outside of their comfort zone but do not stretch them so much that they can't cope with the added responsibilities and pressure. In my head I often think of this example in the same context of an elastic band - you can stretch it, but only so much before it snaps. That is what you should be looking for - to be stretched but not so much that you snap. If you are for example in an individual contributor role and would like to move into a management role - you may not be quite ready to take on a role that is managing a large workforce or requires significant people management experience. While your intentions may be right, your lack of management experience may fit you outside of the scope of search to be successful this type of role. In this example you can move from an individual contributor role to a management role but it may need to be managing a smaller team rather than a larger team. While you are trying to make this transition you can try to pick up some responsibilities in your current role that would give you the skills and experience you need for your next role. Never be afraid to put your hand up to help on a new project or piece of work. You never know when that newly gained experience may come in handy in your career.

  • Disable the Splash Screen in Portable Firefox (and Other Portable Apps)

    - by Mysticgeek
    Portable applications are cool because you can run them on any machine from your thumb drive. What isn’t cool is the annoying splash screens that appear when launching the apps. Here’s how to disable the annoyance. In this example we are using Portable Apps version 1.6.1. Disable Splash Screen in Portable Firefox  To disable the Splash Screen, open up Computer and double-click on your flash drive containing PortableApps.   Now browse to the following location… PortableApps\FirefoxPortable\Other\Source In this directory you’ll find the file FirefoxPortable.ini. Open this file with Notepad… This ini file should look similar to the shot below. By default, the line DisableSplashScreen=False … we just need to change False to True. Then make sure to save the change… Now copy the FirefoxPortable.ini file we just edited. Then go back to the main directory PortableApps \ FirefoxPortable and paste it there. That is all there is to it! Now when you launch Portable Firefox, you won’t have to wait while the Splash Screen displays before you can start using it. If you ever want to revert back to having the Splash Screen display, all you’ll need to do is delete FirefoxPortable.ini from PortableApps \ FirefoxPortable. The process is essentially the same in other PortableApps as well. Just follow the steps shown above. For example here we’re disabling the Splash Screen from KeePassPortable by going into the thumb drive PortableApps \ KeePassPortable \ Other \ Source and changing the KeePassPortable.ini file for DisableSplashScreen to equal True. Save it… Then copy it to the main KeePassPortable directory… If you are annoyed by having to see the Splash Screen every time you launch a portable app, following these steps rids the annoyance!

  • Mocking the Unmockable: Using Microsoft Moles with Gallio

    - by Thomas Weller
    Usual opensource mocking frameworks (like e.g. Moq or Rhino.Mocks) can mock only interfaces and virtual methods. In contrary to that, Microsoft’s Moles framework can ‘mock’ virtually anything, in that it uses runtime instrumentation to inject callbacks in the method MSIL bodies of the moled methods. Therefore, it is possible to detour any .NET method, including non-virtual/static methods in sealed types. This can be extremely helpful when dealing e.g. with code that calls into the .NET framework, some third-party or legacy stuff etc… Some useful collected resources (links to website, documentation material and some videos) can be found in my toolbox on Delicious under this link: http://delicious.com/thomasweller/toolbox+moles A Gallio extension for Moles Originally, Moles is a part of Microsoft’s Pex framework and thus integrates best with Visual Studio Unit Tests (MSTest). However, the Moles sample download contains some additional assemblies to also support other unit test frameworks. They provide a Moled attribute to ease the usage of mole types with the respective framework (there are extensions for NUnit, xUnit.net and MbUnit v2 included with the samples). As there is no such extension for the Gallio platform, I did the few required lines myself – the resulting Gallio.Moles.dll is included with the sample download. With this little assembly in place, it is possible to use Moles with Gallio like that: [Test, Moled] public void SomeTest() {     ... What you can do with it Moles can be very helpful, if you need to ‘mock’ something other than a virtual or interface-implementing method. This might be the case when dealing with some third-party component, legacy code, or if you want to ‘mock’ the .NET framework itself. Generally, you need to announce each moled type that you want to use in a test with the MoledType attribute on assembly level. For example: [assembly: MoledType(typeof(System.IO.File))] Below are some typical use cases for Moles. For a more detailed overview (incl. naming conventions and an instruction on how to create the required moles assemblies), please refer to the reference material above.  Detouring the .NET framework Imagine that you want to test a method similar to the one below, which internally calls some framework method:   public void ReadFileContent(string fileName) {     this.FileContent = System.IO.File.ReadAllText(fileName); } Using a mole, you would replace the call to the File.ReadAllText(string) method with a runtime delegate like so: [Test, Moled] [Description("This 'mocks' the System.IO.File class with a custom delegate.")] public void ReadFileContentWithMoles() {     // arrange ('mock' the FileSystem with a delegate)     System.IO.Moles.MFile.ReadAllTextString = (fname => fname == FileName ? FileContent : "WrongFileName");       // act     var testTarget = new TestTarget.TestTarget();     testTarget.ReadFileContent(FileName);       // assert     Assert.AreEqual(FileContent, testTarget.FileContent); } Detouring static methods and/or classes A static method like the below… public static string StaticMethod(int x, int y) {     return string.Format("{0}{1}", x, y); } … can be ‘mocked’ with the following: [Test, Moled] public void StaticMethodWithMoles() {     MStaticClass.StaticMethodInt32Int32 = ((x, y) => "uups");       var result = StaticClass.StaticMethod(1, 2);       Assert.AreEqual("uups", result); } Detouring constructors You can do this delegate thing even with a class’ constructor. The syntax for this is not all  too intuitive, because you have to setup the internal state of the mole, but generally it works like a charm. For example, to replace this c’tor… public class ClassWithCtor {     public int Value { get; private set; }       public ClassWithCtor(int someValue)     {         this.Value = someValue;     } } … you would do the following: [Test, Moled] public void ConstructorTestWithMoles() {     MClassWithCtor.ConstructorInt32 =            ((@class, @value) => new MClassWithCtor(@class) {ValueGet = () => 99});       var classWithCtor = new ClassWithCtor(3);       Assert.AreEqual(99, classWithCtor.Value); } Detouring abstract base classes You can also use this approach to ‘mock’ abstract base classes of a class that you call in your test. Assumed that you have something like that: public abstract class AbstractBaseClass {     public virtual string SaySomething()     {         return "Hello from base.";     } }      public class ChildClass : AbstractBaseClass {     public override string SaySomething()     {         return string.Format(             "Hello from child. Base says: '{0}'",             base.SaySomething());     } } Then you would set up the child’s underlying base class like this: [Test, Moled] public void AbstractBaseClassTestWithMoles() {     ChildClass child = new ChildClass();     new MAbstractBaseClass(child)         {                 SaySomething = () => "Leave me alone!"         }         .InstanceBehavior = MoleBehaviors.Fallthrough;       var hello = child.SaySomething();       Assert.AreEqual("Hello from child. Base says: 'Leave me alone!'", hello); } Setting the moles behavior to a value of  MoleBehaviors.Fallthrough causes the ‘original’ method to be called if a respective delegate is not provided explicitly – here it causes the ChildClass’ override of the SaySomething() method to be called. There are some more possible scenarios, where the Moles framework could be of much help (e.g. it’s also possible to detour interface implementations like IEnumerable<T> and such…). One other possibility that comes to my mind (because I’m currently dealing with that), is to replace calls from repository classes to the ADO.NET Entity Framework O/R mapper with delegates to isolate the repository classes from the underlying database, which otherwise would not be possible… Usage Since Moles relies on runtime instrumentation, mole types must be run under the Pex profiler. This only works from inside Visual Studio if you write your tests with MSTest (Visual Studio Unit Test). While other unit test frameworks generally can be used with Moles, they require the respective tests to be run via command line, executed through the moles.runner.exe tool. A typical test execution would be similar to this: moles.runner.exe <mytests.dll> /runner:<myframework.console.exe> /args:/<myargs> So, the moled test can be run through tools like NCover or a scripting tool like MSBuild (which makes them easy to run in a Continuous Integration environment), but they are somewhat unhandy to run in the usual TDD workflow (which I described in some detail here). To make this a bit more fluent, I wrote a ReSharper live template to generate the respective command line for the test (it is also included in the sample download – moled_cmd.xml). - This is just a quick-and-dirty ‘solution’. Maybe it makes sense to write an extra Gallio adapter plugin (similar to the many others that are already provided) and include it with the Gallio download package, if  there’s sufficient demand for it. As of now, the only way to run tests with the Moles framework from within Visual Studio is by using them with MSTest. From the command line, anything with a managed console runner can be used (provided that the appropriate extension is in place)… A typical Gallio/Moles command line (as generated by the mentioned R#-template) looks like that: "%ProgramFiles%\Microsoft Moles\bin\moles.runner.exe" /runner:"%ProgramFiles%\Gallio\bin\Gallio.Echo.exe" "Gallio.Moles.Demo.dll" /args:/r:IsolatedAppDomain /args:/filter:"ExactType:TestFixture and Member:ReadFileContentWithMoles" -- Note: When using the command line with Echo (Gallio’s console runner), be sure to always include the IsolatedAppDomain option, otherwise the tests won’t use the instrumentation callbacks! -- License issues As I already said, the free mocking frameworks can mock only interfaces and virtual methods. if you want to mock other things, you need the Typemock Isolator tool for that, which comes with license costs (Although these ‘costs’ are ridiculously low compared to the value that such a tool can bring to a software project, spending money often is a considerable gateway hurdle in real life...).  The Moles framework also is not totally free, but comes with the same license conditions as the (closely related) Pex framework: It is free for academic/non-commercial use only, to use it in a ‘real’ software project requires an MSDN Subscription (from VS2010pro on). The demo solution The sample solution (VS 2008) can be downloaded from here. It contains the Gallio.Moles.dll which provides the here described Moled attribute, the above mentioned R#-template (moled_cmd.xml) and a test fixture containing the above described use case scenarios. To run it, you need the Gallio framework (download) and Microsoft Moles (download) being installed in the default locations. Happy testing…

  • Are Ruby on Rails / Grails the fastest frameworks for getting sites up quickly?

    - by Jon
    I'm considering using Grails for a new website, but am open to other/new programming languages and frameworks. I have done development using J2EE/JSF2, ASP.NET, and PHP. Is Grails or Ruby on Rails pretty much the best way to get functionality up and running quickly?

    In the show LOST, the Swan Station had a button that “had to be pushed” every 100 minutes to avoid disaster.  Several characters in the show took it upon themselves to have faith and religiously push the button, resetting the clock and averting the unknown “disaster”.  There are striking similarities in this story to the code we write every day.  Here are some common ones that I encounter: “I don’t know what it does but the application doesn’t work without it” “I added that code because I saw it in other similar places, I didn’t understand it, but thought it was necessary.” (for consistency, or to make things “work”) “An error message recommended it” “I copied that code” (and didn’t look at what it was doing) “It was suggested in a forum online and it fixed my problem so I left it” In all of these cases we haven’t done our due diligence to understand what the code we are writing is actually doing.  In the rush to get things done it seems like we’re willing to push any button (add any line of code) just to get our desired result and move on.  All of the above explanations are common things we encounter, and are valid ways to work through a problem we have, but when we find a solution to a task we are working on (whether a bug or a feature), we should take a moment to reflect on what we don’t understand.  Remove what isn’t necessary, comprehend and simplify what is.  Why is it detrimental to commit code we don’t understand? Perpetuates unnecessary code If you copy code that isn’t necessary, someone else is more likely to do so, especially peers Perpetuates tech debt Adding unnecessary code leads to extra code that must be understood, maintained and eventually cleaned up in longer lived projects Tech debt begets tech debt as other developers copy or use this code as guidelines in similar situations Increases maintenance How do we know the code is simplified if we don’t understand it? Perpetuates a lack of ownership Makes it seem ok to commit anything so long as it “gets the job done” Perpetuates the notion that programming is magic If we don’t take the time to understand every line of code we add, then we are contributing to the notion that it is simply enough to make the code work, regardless of how. TLDR Don’t commit code that you don’t understand, take the time to understand it, simplify it and then commit it!

  • SQL Server v.Next (Denali) : Troubleshooting Error 18456

    - by AaronBertrand
    I think we've all dealt with error 18456, whether it be an application unable to access SQL Server, credentials changing over time, or a user who can't type a password correctly. The trick to troubleshooting this error number is that the error message returned to the client or application trying to connect is intentionally vague (the error message is similar for most errors, and the state is always 1). In a few cases, some additional information is included, but for the most part several of these...(read more)

  • SQL SERVER – Online Index Rebuilding Index Improvement in SQL Server 2012

    - by pinaldave
    Have you ever faced situation when you see something working and you feel it should not be working? Well, I had similar moments few days ago. I know that SQL Server 2008 supports online indexing. However, I also know that I cannot rebuild index ONLINE if I have used VARCHAR(MAX), NVARCHAR(MAX) or few other data types. While I held my belief very strongly I came across situation, where I had to go online and do little bit reading from Book Online. Here is the similar example. First of all – run following code in SQL Server 2008 or SQL Server 2008 R2. USE TempDB GO CREATE TABLE TestTable (ID INT, FirstCol NVARCHAR(10), SecondCol NVARCHAR(MAX)) GO CREATE CLUSTERED INDEX [IX_TestTable] ON TestTable (ID) GO CREATE NONCLUSTERED INDEX [IX_TestTable_Cols] ON TestTable (FirstCol) INCLUDE (SecondCol) GO USE [tempdb] GO ALTER INDEX [IX_TestTable_Cols] ON [dbo].[TestTable] REBUILD WITH (ONLINE = ON) GO DROP TABLE TestTable GO Now run the same code in SQL Server 2012 version. Observe the difference between both of the execution. You will be get following resultset. In SQL Server 2008/R2 it will throw following error: Msg 2725, Level 16, State 2, Line 1 An online operation cannot be performed for index ‘IX_TestTable_Cols’ because the index contains column ‘SecondCol’ of data type text, ntext, image, varchar(max), nvarchar(max), varbinary(max), xml, or large CLR type. For a non-clustered index, the column could be an include column of the index. For a clustered index, the column could be any column of the table. If DROP_EXISTING is used, the column could be part of a new or old index. The operation must be performed offline. In SQL Server 2012 it will run successfully and will not throw any error. Command(s) completed successfully. I always thought it will throw an error if there is VARCHAR(MAX) or NVARCHAR(MAX) used in table schema definition. When I saw this result it was clear to me that it will be for sure not bug enhancement in SQL Server 2012. For matter for the fact, I always wanted this feature to be added in SQL Server Engine as this will enable ONLINE Index Rebuilding for mission critical tables which needs to be always online. I quickly searched online and landed on Jacob Sebastian’s blog where he has blogged about it as well. Well, is there any other new feature in SQL Server 2012 which gave you good surprise?
