• How (recipe) to build only one kernel module?

  - by Pro Backup

  I have a bug in a Linux kernel module that causes the stock Ubuntu 14.04 kernel to oops (crash). That is why I want to edit/patch the source of only that single kernel module to add some extra debug output. The kernel module in question is mvsas and not necessary to boot. For that reason I don't see any need to update any initrd images. I have read a lot of information (as shown below) and find the setup and build process confusion. I need two recipes: to setup/configure the build environment once steps to do after editing any source file of this kernel module (.c and .h) and converting that edit into a new kernel module (.ko) The sources that have been used are: build one kernel module - Google search http://www.linuxquestions.org/questions/linux-kernel-70/rebuilding-a-single-kernel-module-595116/ http://stackoverflow.com/questions/8744087/how-to-recompile-just-a-single-kernel-module http://www.pixelbeat.org/docs/rebuild_kernel_module.html How do I build a single in-tree kernel module? http://ubuntuforums.org/showthread.php?t=1153067 http://ubuntuforums.org/showthread.php?t=2112166 http://ubuntuforums.org/showthread.php?t=1115593 build one kernel module ubuntu - Google search 'make +single +kernel +module' - Ask Ubuntu 'make +kernel +module' - Ask Ubuntu My makefile results in: No rule to make target `arch/x86/tools/relocs.c', needed '"Invalid module format"' - Ask Ubuntu Driver installation: compiling source code for newer kernel Modprobe: 'Invalid nodule format', yet works after insmod "Symbol version dump" "is missing" - Google search http://stackoverflow.com/questions/9425523/should-i-care-that-the-symbol-version-dump-is-missing-how-do-i-get-one Where can I find the corresponding Module.symvers and .config files for 12.04.3 i386 server?

• Give a session on C++ AMP – here is how

  - by Daniel Moth

  Ever since presenting on C++ AMP at the AMD Fusion conference in June, then the Gamefest conference in August, and the BUILD conference in September, I've had numerous requests about my material from folks that want to re-deliver the same session. The C++ AMP session I put together has evolved over the 3 presentations to its final form that I used at BUILD, so that is the one I recommend you base yours on. Please get the slides and the recording from channel9 (I'll refer to slide numbers below). This is how I've been presenting the C++ AMP session: Context (slide 3, 04:18-08:18) Start with a demo, on my dual-GPU machine. I've been using the N-Body sample (for VS 11 Developer Preview). (slide 4) Use an nvidia slide that has additional examples of performance improvements that customers enjoy with heterogeneous computing. (slide 5) Talk a bit about the differences today between CPU and GPU hardware, leading to the fact that these will continue to co-exist and that GPUs are great for data parallel algorithms, but not much else today. One is a jack of all trades and the other is a number cruncher. (slide 6) Use the APU example from amd, as one indication that the hardware space is still in motion, emphasizing that the C++ AMP solution is a data parallel API, not a GPU API. It has a future proof design for hardware we have yet to see. (slide 7) Provide more meta-data, as blogged about when I first introduced C++ AMP. Code (slide 9-11) Introduce C++ AMP coding with a simplistic array-addition algorithm – the slides speak for themselves. (slide 12-13) index<N>, extent<N>, and grid<N>. (Slide 14-16) array<T,N>, array_view<T,N> and comparison between them. (Slide 17) parallel_for_each. (slide 18, 21) restrict. (slide 19-20) actual restrictions of restrict(direct3d) – the slides speak for themselves. (slide 22) bring it altogether with a matrix multiplication example. (slide 23-24) accelerator, and accelerator_view. (slide 26-29) Introduce tiling incl. tiled matrix multiplication [tiling probably deserves a whole session instead of 6 minutes!]. IDE (slide 34,37) Briefly touch on the concurrency visualizer. It supports GPU profiling, but enhancements specific to C++ AMP we hope will come at the Beta timeframe, which is when I'll be spending more time talking about it. (slide 35-36, 51:54-59:16) Demonstrate the GPU debugging experience in VS 11. Summary (slide 39) Re-iterate some of the points of slide 7, and add the point that the C++ AMP spec will be open for other compiler vendors to implement, even on other platforms (in fact, Microsoft is actively working on that). (slide 40) Links to content – see slide – including where all your questions should go: http://social.msdn.microsoft.com/Forums/en/parallelcppnative/threads.   "But I don't have time for a full blown session, I only need 2 (or just 1, or 3) C++ AMP slides to use in my session on related topic X" If all you want is a small number of slides, you can take some from the session above and customize them. But because I am so nice, I have created some slides for you, including talking points in the notes section. Download them here. Comments about this post by Daniel Moth welcome at the original blog.

• Game development: “Play Now” via website vs. download & install

  - by Inside

  Heyo, I've spent some time looking over the various threads here on gamedev and also on the regular stackoverflow and while I saw a lot of posts and threads regarding various engines that could be used in game development, I haven't seen very much discussion regarding the various platforms that they can be used on. In particular, I'm talking about browser games vs. desktop games. I want to develop a simple 3D networked multiplayer game - roughly on the graphics level of Paper Mario and gameplay with roughly the same level of interaction as a hack & slash action/adventure game - and I'm having a hard time deciding what platform I want to target with it. I have some experience with using C++/Ogre3D and Python/Panda3D (and also some synchronized/networked programming), but I'm wondering if it's worth it to spend the extra time to learn another language and another engine/toolkit just so that the game can be played in a browser window (I'm looking at jMonkeyEngine right now). For simple & short games the newgrounds approach (go to the site, click "play now", instant gratification) seems to work well. What about for more complex games? Is there a point where the complexity of a game is enough for people to say "ok, I'm going to download and play that"? Is it worth it to go with engines that are less-mature, have less documentation, have fewer features, and smaller communities* just so that a (possibly?) larger audience can be reached? Does it make sense to even go with a web-environment for the kind of game that I want to make? Does anyone have any experiences with decisions like this? Thanks! (* With the exception of flash-based engines it seems like most of the other approaches have these downsides when compared to what is available for desktop-based environments. I'd go with flash, but I'm worried that flash's 3D capabilities aren't mature enough right now to do what I want easily. There's also Unity3D, but I'm not sure how I feel about that at all. It seems highly polished, but requires a plugin to be downloaded for the game to be played -- at that rate I might as well have players download my game.)

• T-SQL in Chicago – the LobsterPot teams with DataEducation

  - by Rob Farley

  In May, I’ll be in the US. I have board meetings for PASS at the SQLRally event in Dallas, and then I’m going to be spending a bit of time in Chicago. The big news is that while I’m in Chicago (May 14-16), I’m going to teach my “Advanced T-SQL Querying and Reporting: Building Effectiveness” course. This is a course that I’ve been teaching since the 2005 days, and have modified over time for 2008 and 2012. It’s very much my most popular course, and I love teaching it. Let me tell you why. For years, I wrote queries and thought I was good at it. I was a developer. I’d written a lot of C (and other, more fun languages like Prolog and Lisp) at university, and then got into the ‘real world’ and coded in VB, PL/SQL, and so on through to C#, and saw SQL (whichever database system it was) as just a way of getting the data back. I could write a query to return just about whatever data I wanted, and that was good. I was better at it than the people around me, and that helped. (It didn’t help my progression into management, then it just became a frustration, but for the most part, it was good to know that I was good at this particular thing.) But then I discovered the other side of querying – the execution plan. I started to learn about the translation from what I’d written into the plan, and this impacted my query-writing significantly. I look back at the queries I wrote before I understood this, and shudder. I wrote queries that were correct, but often a long way from effective. I’d done query tuning, but had largely done it without considering the plan, just inferring what indexes would help. This is not a performance-tuning course. It’s focused on the T-SQL that you read and write. But performance is a significant and recurring theme. Effective T-SQL has to be about performance – it’s the biggest way that a query becomes effective. There are other aspects too though – such as using constructs better. For example – I can write code that modifies data nicely, but if I haven’t learned about the MERGE statement and the way that it can impact things, I’m missing a few tricks. If you’re going to do this course, a good place to be is the situation I was in a few years before I wrote this course. You’re probably comfortable with writing T-SQL queries. You know how to make a SELECT statement do what you need it to, but feel there has to be a better way. You can write JOINs easily, and understand how to use LEFT JOIN to make sure you don’t filter out rows from the first table, but you’re coding blind. The first module I cover is on Query Execution. Take a look at the Course Outline at Data Education’s website. The first part of the first module is on the components of a SELECT statement (where I make you think harder about GROUP BY than you probably have before), but then we jump straight into Execution Plans. Some stuff on indexes is in there too, as is simplification and SARGability. Some of this is stuff that you may have heard me present on at conferences, but here you have me for three days straight. I’m sure you can imagine that we revisit these topics throughout the rest of the course as well, and you’d be right. In the second and third modules we look at a bunch of other aspects, including some of the T-SQL constructs that lots of people don’t know, and various other things that can help your T-SQL be, well, more effective. I’ve had quite a lot of people do this course and be itching to get back to work even on the first day. That’s not a comment about the jokes I tell, but because people want to look at the queries they run. LobsterPot Solutions is thrilled to be partnering with Data Education to bring this training to Chicago. Visit their website to register for the course. @rob_farley

• Qt's future in the light of Nokia-Microsoft partnership

  - by Shinnok

  In case you missed it, a lot has happened in the last two day that could potentially impact the Qt framework, for the worse. :-( It will impact the mobile sector in several and probably not currently acknowledged ways, for sure. It started yesterday with Nokia's CEO Stephen Elop internal letter depicting Nokia sitting on a burning platform and the need for a big and aggressive shift in business. A day later, at the Nokia World conference, Nokia announced the partnership with Microsoft , which at the moment resumes to Nokia adopting the Windows Phone 7 platform and development environment, dumping Symbian along the road and tagging Meego as R&D(a pretty dangerous keyword if you ask me), as for Maemo/N900 series i guess it's bye bye for good. I know what you're thinking but no, Qt is not going to be ported to the Window Phone platform. And i'm also scared about this. You can watch the Elop & Ballmer joint press release here. Now after reading this huge thread on the Qt-interest mailing list i can't help but wonder, what is the future of Qt at Nokia, now that they aren't focused(at all?) on Qt anymore(remember the full focus switch on Qt as main development framework for all Nokia products(including Symbian, yes) back in October?). I love Qt, in my opinion it is the only true cross-platform application development framework and one of the few to make C++ development a joy(to the extent possible) and good things has happened to the framework and considerable momentum while under Nokia, thus i am wondering, what are the chances that Qt might suffer a slow death at Nokia after this? Yes i know about KDE.org and the fact that Qt is easily spawnable, but i still feel uneasy. It also must be horrible for all of the efforts either by Nokia employees or third parties that have gone into Symbian and all of the Ovi Store Symbian/Qt content and business and why not, Maemo/Meego. There are also massive layouts planned, i suspect Symbian techs and Qt? I'd love to hear your input on this? Is Qt future safe&proof? LE: The question as been gradually revised, improved and better referenced, thus you might want to throw a quick re-read to see what you might have missed.

• SQL SERVER – Working with FileTables in SQL Server 2012 – Part 2 – Methods to Insert Data Into Table

  - by pinaldave

  Read Part 1 Working with FileTables in SQL Server 2012 – Part 1 – Setting Up Environment In this second part of the series, we will see how we can insert the files into the FileTables. There are two methods to insert the data into FileTables: Method 1: Copy Paste data into the FileTables folder First, find the folder where FileTable will be storing the files. Go to Databases >> Newly Created Database (FileTableDB) >> Expand Tables. Here you will see a new folder which says “FileTables”. When expanded, it gives the name of the newly created “FileTableTb”. Right click on the newly created table, and click on “Explore FileTable Directory”. This will open up the folder where the FileTable data will be stored. When clicked on the option it will open up following folder in my local machine where the FileTable data will be stored. \\127.0.0.1\mssqlserver\FileTableDB\FileTableTb_Dir You can just copy your document just there. I copied few word document there and ran select statement to see the result. USE [FileTableDB] GO SELECT * FROM FileTableTb GO SELECT * returns all the rows. Here is SELECT statement which has only few columns selected from FileTable. SELECT [name] ,[file_type] ,CAST([file_stream] AS VARCHAR) FileContent ,[cached_file_size] ,[creation_time] ,[last_write_time] ,[last_access_time] FROM [dbo].[FileTableTb] GO I believe this is the simplest method to populate FileTable, because you just have to move the files to the specific table. Method 2: T-SQL Insert Statement There are always cases when you might want to programmatically insert the images into SQL Server File table. Here is a quick method which you can use to insert the data in the file table. I have inserted a very small text file using T-SQL, and later on, reading that using SELECT statement demonstrated in method 1 above. INSERT INTO [dbo].[FileTableTb] ([name],[file_stream]) SELECT 'NewFile.txt', * FROM OPENROWSET(BULK N'd:\NewFile.txt', SINGLE_BLOB) AS FileData GO The above T-SQL statement will copy the NewFile.txt to new location. When you run SELECT statement, it will retrieve the file and list in the resultset. Additionally, it returns the content in the SELECT statement as well. I think it is a pretty interesting way to insert the data into the FileTable. SELECT [name] ,[file_type] ,CAST([file_stream] AS VARCHAR) FileContent ,[cached_file_size] ,[creation_time] ,[last_write_time] ,[last_access_time] FROM [dbo].[FileTableTb] GO There are more to FileTable and we will see those in my future blog posts.

• Set a Video as Your Desktop Wallpaper with VLC

  - by DigitalGeekery

  Are you tired of static desktop wallpapers and want something a bit more entertaining? Today we’ll take a look at setting a video as wallpaper in VLC media player. Download and install VLC player. You’ll find the download link below. Open VLC and select Tools > Preferences. On the Preferences windows, select the Video button on the left. Under Video Settings, select DirectX video output from the Output dropdown list. Click Save before exiting and then restart VLC. Next, select a video and begin playing it with VLC. Right-click on the screen, select Video, then DirectX Wallpaper.   You can achieve the same result by selecting Video from the Menu and clicking DirectX Wallpaper.   If you’re using Windows Aero Themes, you may get the warning message below and your theme will switch automatically to a basic theme.   After the Wallpaper is enabled, minimize VLC player and enjoy the show as you work.     When you are ready to switch back to your normal wallpaper, click Video, and then close out of VLC.   Occasionally we had to manually change our wallpaper back to normal. You can do that by right clicking on the desktop and selecting your theme.   Conclusion This might not make the most productive desktop environment, but it is pretty cool. It’s definitely not the same old boring wallpaper!

• Using a parser to locate faulty code

  - by ryan.riverside

  Lately I've been working a lot in PHP and have run into an abnormally large number of parsing errors. I realize these are my own fault and a result of sloppy initial coding on my part, but it's getting to the point that I'm spending more time resolving tags than developing. In the interest of not slamming my productivity, are there any tricks to locating the problem in the code? What I'd really be looking for would be a line to put in the code which would output the entire faulty tag in the parsing error, or something similar. Purely for reference sake, my current error is Parse error: syntax error, unexpected '}' in /home/content/80/9480880/html/cache/tpl_prosilver_viewtopic_body.html.php on line 50 (which refers to this): </dd><dd><?php if ($_poll_option_val['POLL_OPTION_RESULT'] == 0) { echo ((isset($this->_rootref['L_NO_VOTES'])) ? $this->_rootref['L_NO_VOTES'] : ((isset($user->lang['NO_VOTES'])) ? $user->lang['NO_VOTES'] : '{ NO_VOTES }')); } else { echo $_poll_option_val['POLL_OPTION_PERCENT']; } ?></dd> </dl> <?php }} if ($this->_rootref['S_DISPLAY_RESULTS']) { ?> <dl> <dt>&nbsp;</dt> <dd class="resultbar"><?php echo ((isset($this->_rootref['L_TOTAL_VOTES'])) ? $this->_rootref['L_TOTAL_VOTES'] : ((isset($user->lang['TOTAL_VOTES'])) ? $user->lang['TOTAL_VOTES'] : '{ TOTAL_VOTES }')); ?> : <?php echo (isset($this->_rootref['TOTAL_VOTES'])) ? $this->_rootref['TOTAL_VOTES'] : ''; ?></dd> </dl> <?php } if ($this->_rootref['S_CAN_VOTE']) { ?> <dl style="border-top: none;"> <dt>&nbsp;</dt> <dd class="resultbar"><input type="submit" name="update" value="<?php echo ((isset($this->_rootref['L_SUBMIT_VOTE'])) ? $this->_rootref['L_SUBMIT_VOTE'] : ((isset($user->lang['SUBMIT_VOTE'])) ? $user->lang['SUBMIT_VOTE'] : '{ SUBMIT_VOTE }')); ?>" class="button1" /></dd> </dl> <?php } if (! $this->_rootref['S_DISPLAY_RESULTS']) { ?> <dl style="border-top: none;"> <dt>&nbsp;</dt> <dd class="resultbar"><a href="<?php echo (isset($this->_rootref['U_VIEW_RESULTS'])) ? $this->_rootref['U_VIEW_RESULTS'] : ''; ?>"><?php echo ((isset($this->_rootref['L_VIEW_RESULTS'])) ? $this->_rootref['L_VIEW_RESULTS'] : ((isset($user->lang['VIEW_RESULTS'])) ? $user->lang['VIEW_RESULTS'] : '{ VIEW_RESULTS }')); ?></a></dd> </dl> <?php } ?> </fieldset></div>

• Manage and Monitor Identity Ranges in SQL Server Transactional Replication

  - by Yaniv Etrogi

  Problem When using transactional replication to replicate data in a one way topology from a publisher to a read-only subscriber(s) there is no need to manage identity ranges. However, when using  transactional replication to replicate data in a two way replication topology - between two or more servers there is a need to manage identity ranges in order to prevent a situation where an INSERT commands fails on a PRIMARY KEY violation error  due to the replicated row being inserted having a value for the identity column which already exists at the destination database. Solution There are two ways to address this situation: Assign a range of identity values per each server. Work with parallel identity values. The first method requires some maintenance while the second method does not and so the scripts provided with this article are very useful for anyone using the first method. I will explore this in more detail later in the article. In the first solution set server1 to work in the range of 1 to 1,000,000,000 and server2 to work in the range of 1,000,000,001 to 2,000,000,000.  The ranges are set and defined using the DBCC CHECKIDENT command and when the ranges in this example are well maintained you meet the goal of preventing the INSERT commands to fall due to a PRIMARY KEY violation. The first insert at server1 will get the identity value of 1, the second insert will get the value of 2 and so on while on server2 the first insert will get the identity value of 1000000001, the second insert 1000000002 and so on thus avoiding a conflict. Be aware that when a row is inserted the identity value (seed) is generated as part of the insert command at each server and the inserted row is replicated. The replicated row includes the identity column’s value so the data remains consistent across all servers but you will be able to tell on what server the original insert took place due the range that  the identity value belongs to. In the second solution you do not manage ranges but enforce a situation in which identity values can never get overlapped by setting the first identity value (seed) and the increment property one time only during the CREATE TABLE command of each table. So a table on server1 looks like this: CREATE TABLE T1 (  c1 int NOT NULL IDENTITY(1, 5) PRIMARY KEY CLUSTERED ,c2 int NOT NULL ); And a table on server2 looks like this: CREATE TABLE T1(  c1 int NOT NULL IDENTITY(2, 5) PRIMARY KEY CLUSTERED ,c2 int NOT NULL ); When these two tables are inserted the results of the identity values look like this: Server1:  1, 6, 11, 16, 21, 26… Server2:  2, 7, 12, 17, 22, 27… This assures no identity values conflicts while leaving a room for 3 additional servers to participate in this same environment. You can go up to 9 servers using this method by setting an increment value of 9 instead of 5 as I used in this example. Continues…

• Media keys play/pause globally worked in 12.10, not in 13.10

  - by Stéphane Gourichon

  Laptop media keys On Asus n55sf laptop, there are a dedicated keys for volume up, volume down, mute, [play/pause], stop, launch (plus a dozen Fn-key combinations). In 12.10 most worked. (Overall is seems unrelated to desktop environment used, stating it for the sake of completeness.) On Ubuntu 12.10 under XFCE they just worked. That is: when a player like rhythmbox or totem was started, it would alternate between play and pause. Interestingly, if several were started, they would alternate independently. E.g. use mouse to pause rhythmbox, launch totem, and one hit on [play/pause] key would pause one and resume the other. Keys Next,Previous and Stop worked as expected in any program. In 13.10 most still work, but play/skip related ignored. On Xubuntu 13.10 (XFCE too) the volume keys work but the [play/pause], stop, next and prev are ignored. Not tried regular Ubuntu 13.10 (Unity). Search before you ask Here are a few facts: https://wiki.ubuntu.com/Hotkeys/Architecture is ummutable and mentions Ubuntu 9.10. https://wiki.ubuntu.com/Hotkeys/Troubleshooting is also outdated as it mentions /usr/share/doc/udev/README.keymap.txt which no longer exists. On 12.10 and 13.10 versions, at XFCE level (as visible by xfconf-query or using xfce4-settings-manager) there are a couple of shortcut for keys like XF86Calculator or XF86TouchpadToggle but nothing related to volume prev/next/play/stop, which is okay. XF86Audio substring doesn't appear in /etc (which is normal) Kernel-level test: "showkey -s" on console shows that keys Next,Play/Pause,Previous,Stop are keycodes 163,164,165,166. Nothing relevant in /etc about that. Reports https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1072371 and https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1012365 suggest to adjust at udev level. Alas, the udev tutorials I found ( e.g. https://wiki.debian.org/udev ) don't even mention keyboard. A thread in french seems to deal with a similar issue: https://forum.ubuntu-fr.org/viewtopic.php?id=1395051. @sudo evtest /dev/input/event3@, in X as well as on plain console, reports events on key pressed and repeats, but nothing when pressing those media keys. Is udev a dead end ? Questions How did it work in 12.10 ? Through udev ? Something else ? Any other hint ?

• Two small issues with Windows Phone 7 ApplicationBar buttons (and workaround)

  - by Laurent Bugnion

  When you work with the ApplicationBar in Windows Phone 7, you notice very fast that it is not quite a component like the others. For example, the ApplicationBarIconButton element is not a dependency object, which causes issues because it is not possible to add attached properties to it. Here are two other issues I stumbled upon, and what workaround I used to make it work anyway. Finding a button by name returns null Since the ApplicationBar is not in the tree of the Silverlight page, finding an element by name fails. For example consider the following code: <phoneNavigation:PhoneApplicationPage.ApplicationBar> <shell:ApplicationBar> <shell:ApplicationBar.Buttons> <shell:ApplicationBarIconButton IconUri="/Resources/edit.png" Click="EditButtonClick" x:Name="EditButton"/> <shell:ApplicationBarIconButton IconUri="/Resources/cancel.png" Click="CancelButtonClick" x:Name="CancelButton"/> </shell:ApplicationBar.Buttons> </shell:ApplicationBar> </phoneNavigation:PhoneApplicationPage.ApplicationBar> with private void EditButtonClick( object sender, EventArgs e) { CancelButton.IsEnabled = false; // Fails, CancelButton is always null } The CancelButton, even though it is named through an x:Name attribute, and even though it appears in Intellisense in the code behind, is null when it is needed. To solve the issue, I use the following code: public enum IconButton { Edit = 0, Cancel = 1 } public ApplicationBarIconButton GetButton( IconButton which) { return ApplicationBar.Buttons[(int) which] as ApplicationBarIconButton; } private void EditButtonClick( object sender, EventArgs e) { GetButton(IconButton.Cancel).IsEnabled = false; } Updating a Binding when the icon button is clicked In Silverlight, a Binding on a TextBox’s Text property can only be updated in two circumstances: When the TextBox loses the focus. Explicitly by placing a call in code. In WPF, there is a third option, updating the Binding every time that the Text property changes (i.e. every time that the user types a character). Unfortunately this option is not available in Silverlight). To select option 1, 2 (and in WPF, 3), you use the Mode property of the Binding class. The issue here is that pressing a button on the ApplicationBar does not remove the focus from the TextBox where the user is currently typing. If the button is a Save button, this is super annoying: The Binding does not get updated on the data object, the object is saved anyway with the old state, and noone understands what just happened. In order to solve this, you can make sure that the Binding is updated explicitly when the button is pressed, with the following code: private void SaveButtonClick(object sender, EventArgs e) { // Force update binding first var binding = MessageTextBox.GetBindingExpression( TextBox.TextProperty); binding.UpdateSource(); // Property was updated for sure, now we can save var vm = DataContext as MainViewModel; vm.Save(); } Obviously this is less maintainable than the usual way to do things in Silverlight. So be careful when using the ApplicationBar and remember that it is not a Silverlight element like the others!! Happy coding!

• Issue 15: Oracle Exadata Marketing Campaigns

  - by rituchhibber

       PARTNER FOCUS Oracle ExadataMarketing Campaign Steve McNickleVP Europe, cVidya Steve McNickle is VP Europe for cVidya, an innovative provider of revenue intelligence solutions for telecom, media and entertainment service providers including AT&T, BT, Deutsche Telecom and Vodafone. The company's product portfolio helps operators and service providers maximise margins, improve customer experience and optimise ecosystem relationships through revenue assurance, fraud and security management, sales performance management, pricing analytics, and inter-carrier services. cVidya has partnered with Oracle for more than a decade. RESOURCES -- Oracle PartnerNetwork (OPN) Oracle Exastack Program Oracle Exastack Optimized Oracle Exastack Labs and Enablement Resources Oracle Engineered Systems Oracle Communications cVidya SUBSCRIBE FEEDBACK PREVIOUS ISSUES Are you ready for Oracle OpenWorld this October? -- -- Please could you tell us a little about cVidya's partnering history with Oracle, and expand on your Oracle Exastack accreditations? "cVidya was established just over ten years ago and we've had a strong relationship with Oracle almost since the very beginning. Through our Revenue Intelligence work with some of the world's largest service providers we collect tremendous amounts of information, amounting to billions of records per day. We help our clients to collect, store and analyse that data to ensure that their end customers are getting the best levels of service, are billed correctly, and are happy that they are on the correct price plan. We have been an Oracle Gold level partner for seven years, and crucially just two months ago we were also accredited as Oracle Exastack Optimized for MoneyMap, our core Revenue Assurance solution. Very soon we also expect to be Oracle Exastack Optimized DRMap, our Data Retention solution." What unique capabilities and customer benefits does Oracle Exastack add to your applications? "Oracle Exastack enables us to deliver radical benefits to our customers. A typical mobile operator in the UK might handle between 500 million and two billion call data record details daily. Each transaction needs to be validated, billed correctly and fraud checked. Because of the enormous volumes involved, our clients demand scalable infrastructure that allows them to efficiently acquire, store and process all that data within controlled cost, space and environmental constraints. We have proved that the Oracle Exadata system can process data up to seven times faster and load it as much as 20 times faster than other standard best-of-breed server approaches. With the Oracle Exadata Database Machine they can reduce their datacentre equipment from say, the six or seven cabinets that they needed in the past, down to just one. This dramatic simplification delivers incredible value to the customer by cutting down enormously on all of their significant cost, space, energy, cooling and maintenance overheads." "The Oracle Exastack Program has given our clients the ability to switch their focus from reactive to proactive. Traditionally they may have spent 80 percent of their day processing, and just 20 percent enabling end customers to see advanced analytics, and avoiding issues before they occur. With our solutions and Oracle Exadata they can now switch that balance around entirely, resulting not only in reduced revenue leakage, but a far higher focus on proactive leakage prevention. How has the Oracle Exastack Program transformed your customer business? "We can already see the impact. Oracle solutions allow our delivery teams to achieve successful deployments, happy customers and self-satisfaction, and the power of Oracle's Exa solutions is easy to measure in terms of their transformational ability. We gained our first sale into a major European telco by demonstrating the major performance gains that would transform their business. Clients can measure the ease of organisational change, the early prevention of business issues, the reduction in manpower required to provide protection and coverage across all their products and services, plus of course end customer satisfaction. If customers know that that service is provided accurately and that their bills are calculated correctly, then over time this satisfaction can be attributed to revenue intelligence and the underlying systems which provide it. Combine this with the further integration we have with the other layers of the Oracle stack, including the telecommunications offerings such as NCC, OCDM and BRM, and the result is even greater customer value—not to mention the increased speed to market and the reduced project risk." What does the Oracle Exastack community bring to cVidya, both in terms of general benefits, and also tangible new opportunities and partnerships? "A great deal. We have participated in the Oracle Exastack community heavily over the past year, and have had lots of meetings with Oracle and our peers around the globe. It brings us into contact with like-minded, innovative partners, who like us are not happy to just stand still and want to take fresh technology to their customer base in order to gain enhanced value. We identified three new partnerships in each of two recent meetings, and hope these will open up new opportunities, not only in areas that exactly match where we operate today, but also in some new associative areas that will expand our reach into new business sectors. Notably, thanks to the Exastack community we were invited on stage at last year's Oracle OpenWorld conference. Appearing so publically with Oracle senior VP Judson Althoff elevated awareness and visibility of cVidya and has enabled us to participate in a number of other events with Oracle over the past eight months. We've been involved in speaking opportunities, forums and exhibitions, providing us with invaluable opportunities that we wouldn't otherwise have got close to." How has Exastack differentiated cVidya as an ISV, and helped you to evolve your business to the next level? "When we are selling to our core customer base of Tier 1 telecommunications providers, we know that they want more than just software. They want an enduring partnership that will last many years, they want innovation, and a forward thinking partner who knows how to guide them on where they need to be to meet market demand three, five or seven years down the line. Membership of respected global bodies, such as the Telemanagement Forum enables us to lead standard adherence in our area of business, giving us a lot of credibility, but Oracle is also involved in this forum with its own telecommunications portfolio, strengthening our position still further. When we approach CEOs, CTOs and CIOs at the very largest Tier 1 operators, not only can we easily show them that our technology is fantastic, we can also talk about our strong partnership with Oracle, and our joint embracing of today's standards and tomorrow's innovation." Where would you like cVidya to be in one year's time? "We want to get all of our relevant products Oracle Exastack Optimized. Our MoneyMap Revenue Assurance solution is already Exastack Optimised, our DRMAP Data Retention Solution should be Exastack Optimised within the next month, and our FraudView Fraud Management solution within the next two to three months. We'd then like to extend our Oracle accreditation out to include other members of the Oracle Engineered Systems family. We are moving into the 'Big Data' space, and so we're obviously very keen to work closely with Oracle to conduct pilots, map new technologies onto Oracle Big Data platforms, and embrace and measure the benefits of other Oracle systems, namely Oracle Exalogic Elastic Cloud, the Oracle Exalytics In-Memory Machine and the Oracle SPARC SuperCluster. We would also like to examine how the Oracle Database Appliance might benefit our Tier 2 service provider customers. Finally, we'd also like to continue working with the Oracle Communications Global Business Unit (CGBU), furthering our integration with Oracle billing products so that we are able to quickly deploy fraud solutions into Oracle's Engineered System stack, give operational benefits to our clients that are pre-integrated, more cost-effective, and can be rapidly deployed rapidly and producing benefits in three months, not nine months." Chris Baker ,Senior Vice President, Oracle Worldwide ISV-OEM-Java Sales Chris Baker is the Global Head of ISV/OEM Sales responsible for working with ISV/OEM partners to maximise Oracle's business through those partners, whilst maximising those partners' business to their end users. Chris works with partners, customers, innovators, investors and employees to develop innovative business solutions using Oracle products, services and skills. Firstly, could you please explain Oracle's current strategy for ISV partners, globally and in EMEA? "Oracle customers use independent software vendor (ISV) applications to run their businesses. They use them to generate revenue and to fulfil obligations to their own customers. Our strategy is very straight-forward. We want all of our ISV partners and OEMs to concentrate on the things that they do the best – building applications to meet the unique industry and functional requirements of their customer. We want to ensure that we deliver a best in class application platform so the ISV is free to concentrate their effort on their application functionality and user experience We invest over four billion dollars in research and development every year, and we want our ISVs to benefit from all of that investment in operating systems, virtualisation, databases, middleware, engineered systems, and other hardware. By doing this, we help them to reduce their costs, gain more consistency and agility for quicker implementations, and also rapidly differentiate themselves from other application vendors. It's all about simplification because we believe that around 25 to 30 percent of the development costs incurred by many ISVs are caused by customising infrastructure and have nothing to do with their applications. Our strategy is to enable our ISV partners to standardise their application platform using engineered architecture, so they can write once to the Oracle stack and deploy seamlessly in the cloud, on-premise, or in hybrid deployments. It's really important that architecture is the same in order to keep cost and time overheads at a minimum, so we provide standardisation and an environment that enables our ISVs to concentrate on the core business that makes them the most money and brings them success." How do you believe this strategy is helping the ISVs to work hand-in-hand with Oracle to ensure that end customers get the industry-leading solutions that they need? "We work with our ISVs not just to help them be successful, but also to help them market themselves. We have something called the 'Oracle Exastack Ready Program', which enables ISVs to publicise themselves as 'Ready' to run the core software platforms that run on Oracle's engineered systems including Exadata and Exalogic. So, for example, they can become 'Database Ready' which means that they use the latest version of Oracle Database and therefore can run their application without modification on Exadata or the Oracle Database Appliance. Alternatively, they can become WebLogic Ready, Oracle Linux Ready and Oracle Solaris Ready which means they run on the latest release and therefore can run their application, with no new porting work, on Oracle Exalogic. Those 'Ready' logos are important in helping ISVs advertise to their customers that they are using the latest technologies which have been fully tested. We now also have Exadata Ready and Exalogic Ready programmes which allow ISVs to promote the certification of their applications on these platforms. This highlights these partners to Oracle customers as having solutions that run fluently on the Oracle Exadata Database Machine, the Oracle Exalogic Elastic Cloud or one of our other engineered systems. This makes it easy for customers to identify solutions and provides ISVs with an avenue to connect with Oracle customers who are rapidly adopting engineered systems. We have also taken this programme to the next level in the shape of 'Oracle Exastack Optimized' for partners whose applications run best on the Oracle stack and have invested the time to fully optimise application performance. We ensure that Exastack Optimized partner status is promoted and supported by press releases, and we help our ISVs go to market and differentiate themselves through the use our technology and the standardisation it delivers. To date we have had several hundred organisations successfully work through our Exastack Optimized programme." How does Oracle's strategy of offering pre-integrated open platform software and hardware allow ISVs to bring their products to market more quickly? "One of the problems for many ISVs is that they have to think very carefully about the technology on which their solutions will be deployed, particularly in the cloud or hosted environments. They have to think hard about how they secure these environments, whether the concern is, for example, middleware, identity management, or securing personal data. If they don't use the technology that we build-in to our products to help them to fulfil these roles, they then have to build it themselves. This takes time, requires testing, and must be maintained. By taking advantage of our technology, partners will now know that they have a standard platform. They will know that they can confidently talk about implementation being the same every time they do it. Very large ISV applications could once take a year or two to be implemented at an on-premise environment. But it wasn't just the configuration of the application that took the time, it was actually the infrastructure - the different hardware configurations, operating systems and configurations of databases and middleware. Now we strongly believe that it's all about standardisation and repeatability. It's about making sure that our partners can do it once and are then able to roll it out many different times using standard componentry." What actions would you recommend for existing ISV partners that are looking to do more business with Oracle and its customer base, not only to maximise benefits, but also to maximise partner relationships? "My team, around the world and in the EMEA region, is available and ready to talk to any of our ISVs and to explore the possibilities together. We run programmes like 'Excite' and 'Insight' to help us to understand how we can help ISVs with architecture and widen their environments. But we also want to work with, and look at, new opportunities - for example, the Machine-to-Machine (M2M) market or 'The Internet of Things'. Over the next few years, many millions, indeed billions of devices will be collecting massive amounts of data and communicating it back to the central systems where ISVs will be running their applications. The only way that our partners will be able to provide a single vendor 'end-to-end' solution is to use Oracle integrated systems at the back end and Java on the 'smart' devices collecting the data – a complete solution from device to data centre. So there are huge opportunities to work closely with our ISVs, using Oracle's complete M2M platform, to provide the infrastructure that enables them to extract maximum value from the data collected. If any partners don't know where to start or who to contact, then they can contact me directly at [email protected] or indeed any of our teams across the EMEA region. We want to work with ISVs to help them to be as successful as they possibly can through simplification and speed to market, and we also want all of the top ISVs in the world based on Oracle." What opportunities are immediately opened to new ISV partners joining the OPN? "As you know OPN is very, very important. New members will discover a huge amount of content that instantly becomes accessible to them. They can access a wealth of no-cost training and enablement materials to build their expertise in Oracle technology. They can download Oracle software and use it for development projects. They can help themselves become more competent by becoming part of a true community and uncovering new opportunities by working with Oracle and their peers in the Oracle Partner Network. As well as publishing massive amounts of information on OPN, we also hold our global Oracle OpenWorld event, at which partners play a huge role. This takes place at the end of September and the beginning of October in San Francisco. Attending ISV partners have an unrivalled opportunity to contribute to elements such as the OpenWorld / OPN Exchange, at which they can talk to other partners and really begin thinking about how they can move their businesses on and play key roles in a very large ecosystem which revolves around technology and standardisation." Finally, are there any other messages that you would like to share with the Oracle ISV community? "The crucial message that I always like to reinforce is architecture, architecture and architecture! The key opportunities that ISVs have today revolve around standardising their architectures so that they can confidently think: “I will I be able to do exactly the same thing whenever a customer is looking to deploy on-premise, hosted or in the cloud”. The right architecture is critical to being competitive and to really start changing the game. We want to help our ISV partners to do just that; to establish standard architecture and to seize the opportunities it opens up for them. New market opportunities like M2M are enormous - just look at how many devices are all around you right now. We can help our partners to interface with these devices more effectively while thinking about their entire ecosystem, rather than just the piece that they have traditionally focused upon. With standardised architecture, we can help people dramatically improve their speed, reach, agility and delivery of enhanced customer satisfaction and value all the way from the Java side to their centralised systems. All Oracle ISV partners must take advantage of these opportunities, which is why Oracle will continue to invest in and support them." -- Gergely Strbik is Oracle Hardware and Software Product Manager for Avnet in Hungary. Avnet Technology Solutions is an OracleValue Added Distributor focused on the development of the existing Oracle channel. This includes the recruitment and enablement of Oracle partners as well as driving deeper adoption of Oracle's technology and application products within the IT channel. "The main business benefits of ODA for our customers and partners are scalability, flexibility, a great price point for the high performance delivered, and the easily configurable embedded Linux operating system. People welcome a lower point of entry and the ability to grow capacity on demand as their business expands." "Marketing and selling the ODA requires another way of thinking because it is an appliance. We have to transform the ways in which our partners and customers think from buying hardware and software independently to buying complete solutions. Successful early adopters and satisfied customer reactions will certainly help us to sell the ODA. We will have more experience with the product after the first deliveries and installations—end users need to see the power and benefits for themselves." "Our typical ODA customers will be those looking for complete solutions from a single reseller partner who is also able to manage the appliance. They will have enjoyed using Oracle Database but now want a new product that is able to unlock new levels of performance. A higher proportion of potential customers will come from our existing Oracle base, with around 30% from new business, but we intend to evangelise the ODA on the market to see how we can change this balance as all our customers adjust to the concept of 'Hardware and Software, Engineered to Work Together'. -- Back to the welcome page

• How to install Awesome WM without root access?

  - by ssice

  I want to install the Awesome window manager. In the environment where I want to configure it I don't have root access. I do have a machine were I can be root (I use for this a virtual machine in my laptop). I have tried the following: $ sudo apt-get install awesome The following packages are about to be installed: awesome libev3 libid3tag0 libimlib2 liblua5.1-0 libxcb-icccm1 libxcb-image0 libxcb-keysyms1 libxcb-property1 libxcb-randr0 libxcb-xinerama0 libxcb-xtest0 libxdg-basedir1 menu rlwrap Do you want to continue [Y/n]? n I do now have the list of dependencies for awesome, so I downloaded them all. For that, I did the following. $ pkgs="awesome libev3 libid3tag0 libimlib2 liblua5.1-0 libxcb-icccm1 libxcb-image0 libxcb-keysyms1 libxcb-property1 libxcb-randr0 libxcb-xinerama0 libxcb-xtest0 libxdg-basedir1 menu rlwrap" # this is just for not writing it all ;) $ sudo apt-get install --download-only $pkgs .... $ mkdir -p /tmp/x_debs $ for pkg in $pkgs; do cp /var/cache/apt/archives/$pkg* /tmp/x_debs/; done [ copies all *.deb from my dependencies to /tmp/x_debs ] Now, I want to install the dependencies. For that, I setup a fake dpkg install in my home folder: $ mkdir $HOME/root $ mkdir -p $HOME/root/var/lib/dpkg/{triggers,updates} $ touch $HOME/root/var/lib/dpkg/{available,status} Now I tried to install with dpkg, but I could not: $ dpkg --force-not-root --root=$HOME/root --recursive -i /tmp/x_debs It failed while trying to set permissions for the packages and running chroot. As I do have root access in this machine, I ran it with privileges: $ sudo dpkg --root=$HOME/root --recursive -i /tmp/x_debs Then I had a lot of stuff (i.e., everything: dependencies and the own WM) installed inside $HOME/root. Particularly, xcb-* libraries were installed in $HOME/root/usr/lib and the awesome binary in $HOME/root/usr/bin/awesome. If I try to execute awesome as is I get as an error that libraries could not be loaded. That's normal, as they are not in /usr/lib nor in /lib. So I ran export LD_LIBRARY_PATH=$HOME/root/usr/lib:$HOME/root/lib:${LD_LIBRARY_PATH} and awesome would try to load. However, I could not make gdm to run awesome within gnome or replacing it. I did it this way so I can copy everything in my $HOME/root folder, paste it in the other machine and have it running. Is there any other way (to have less wasted space maybe..) to do this? How can I tell gdm to exec awesome without root access?

• regarding the Windows Phone 7 series, XNA and Visual Basic

  - by Chris Williams

  as long as we're talking about VB... I figured I would share this as well. Hi everyone, I'm about to express a sentiment that might ruffle a few feathers, but I think most of you know me well enough to know I love like accept VB for what it is and that what I'm about to say is with good intentions. (The rest of you, who don't know me, please take my word for it.) The world is full of VB developers, I was one of them for a long time. I think it's safe to assume that none of us are ignorant people who require handholding. We're working professionals, making a living by using our skills as developers. I'm also willing to bet that quite a few of us are fluent in C# as well as VB. It may not be your preferred language, but many of you can do it and you prove that nearly every day. Honestly, I don't know ANY developers or consultants that have only known ONE language ever. So it pains me greatly when I see the word "CAN'T" being tossed around like a crutch... as in "we CAN'T develop for the windows phone or we CAN'T develop XNA games." At MIX, Microsoft hath decreed that C# is the language of choice for developing for the Windows Phone 7. I think it's a safe bet that you won't see VB support if it isn't there already. (Just like XNA... which is up to version 4.0 by now.)  So what? (Yeah... I said it.) I think everyone here can agree that actual coding is only one part of software design and development. There is nothing stopping ANY of you from beginning the process of designing your killer phone app, writing up specs, requirements, doing UI design, workflow, mockups, storyboards, art, etc.... None of these things are language dependent. IF by the time you've got that stuff out of the way, and there's still no VB support, then start doing some rapid prototyping of your app in C# (I know, I know... heresy!)  You still have to spend time learning how the phone does things, what UI tricks do what, what paradigms make sense, how to use to accelerometer and the tilt and the multitouch functionality. I can guarantee you that time spent doing this is a great investment, no matter WHAT extension your code files have. Eventually, you may have a working prototype. IF by this time, there's STILL no VB support... fret not, you've made significant progress on your app. You've designed it, prototyped it, figured out how to use the phone specific features... so you might as well finish it and pat yourself on the back for learning something new... and possibly being first to market with your new app. I'll be happy to argue any and all of these points online or off with anyone who cares to do so, but there is one undeniable point that you simply can't argue:  Your potential customers do not care AT ALL what programming language you used to write the app they are about to purchase. They care that it works. If your biggest concern is being first to market, than stop complaining and get busy because you're running out of time and the 3000+ people who were at MIX certainly aren't waiting for you. They've already started working on their apps.

• Error Using 32 vs. 64 bit SharePoint 2007 DLLs with PowerShell

  - by Brian Jackett

  Next time you fire up PowerShell to work with the SharePoint API make sure you launch the proper bit version of PowerShell.  Last week I had an interesting error that led to this blog post.  Travel back in time a little bit with me to see where this 32 vs. 64 bit debate started. History     Ever since the first pre-beta bits of Office 2010 landed in my lap I have been questioning whether it’s better to run 32 or 64 bit applications on a 64 bit host operating system.  In relation to Office 2010 I heard a number of arguments for 32 bit including this link from the Office 2010 Engineering team.  Given my typical usage scenarios 32 bit seemed the way to go since I wasn’t a “super RAM hungry” Excel user or the like. The Problem     Since I had chosen 32 bit Office 2010, I tried to stick with 32 bit version of other programs that I run assuming the same benefits and rules applied to other applications.  This is where I was wrong.  Last week I was attempting to use 32 bit PowerShell ISE (Integrated Scripting Environment) on a 64 bit WSS 3.0 server.  When trying to reference the 64 bit SharePoint DLLs I got the following errors about not being able to find the web application.     I have run into these errors when I have hosts file issues or improper permissions to the farm / site collection but these were not the case.  After taking a quick spin around the interwebs I ran across the below forum post comment and another MSDN forum reply that explained the error.  Turns out that sometimes it’s not possible to run 32 bit applications against a 64 bit OS / farm / assembly / etc. …the problem could also be because your SharePoint is 64-Bit but your app is running in 32-bit mode     I quickly exited 32 bit PowerShell ISE and ran the same code under 64 bit PowerShell ISE.  All errors were gone and the script ran successfully.   Conclusion     The rules of 32 vs. 64 bit interoperability do not always apply evenly across all applications and scenarios.  In my case I wasn’t able to run 32 bit PowerShell against 64 bit SharePoint DLLs.  I’m updating all of my links and shortcuts to use 64 bit PowerShell where appropriate.  I’m quite surprised it has taken me this long to run into this error, but sometimes blind luck is all that keeps you from running into errors.  Lesson learned and hopefully this can benefit you as well.  Happy SharePointing all!         -Frog Out   Links http://blogs.technet.com/b/office2010/archive/2010/02/23/understanding-64-bit-office.aspx http://social.msdn.microsoft.com/Forums/en-US/sharepointdevelopment/thread/a732cb83-c2ef-4133-b04e-86477b72bbe3/ http://stackoverflow.com/questions/266255/filenotfoundexception-with-the-spsite-constructor-whats-the-problem

Agenda and session abstracts are available now so you can be ready for the live event when it kicks off today, July 10, 9am to 1pm PST / 12pm to 4pm EST / 1pm to 5pm BRT. Podcast: The Role of the Cloud Architect - Part 1/3 In part one of this three-part conversation, cloud architects Ron Batra (AT&T) and James Baty (Oracle) talk about how cloud computing is driving the supply-chaining of IT and the "democratization of the activity of architecture." Middleware and Cloud Computing Book | Tom Laszewski Cloud migration expert Tom Laszewski describes Middleware and Cloud Computing by Frank Munz as "one of only a couple books that really discuss AWS and Oracle in depth." Cloud computing moves from fad to foundation | David Linthicum "When enterprises make cloud computing work, they view the application of the technology as a trade secret of sorts, so there are no press releases or white papers," says David Linthicum. "Indeed, if you see one presentation around a successful cloud computing case study, you can bet you're not hearing about 100 more." Oracle Real-Time Decisions: Combined Likelihood Models | Lukas Vermeer Lukas Vermeer concludes his extensive series of posts on decision models with a look "an advanced approach to amalgamate models, taking us to a whole new level of predictive modeling and analytical insights; combination models predicting likelihoods using multiple child models." Running Oracle BPM 11g PS5 Worklist Task Flow and Human Task Form on Non-SOA Domain | Andrejus Baranovskis "With a standard setup, both the BPM worklist application and the Human task form run on the same SOA domain, where the BPM process is running," says Oracle ACE Director Andrejus Baranovskis. "While this work fine, this is not what we want in the development, test and production environment." BAM design pointers | Kavitha Srinivasan "When using EMS (Enterprise Message Source) as a BAM feed, the best practice is to use one EMS to write to one Data Object," says Oracle Fusion Middleware A-Team blogger Kavitha Srinivasan. "There is a possibility of collisions and duplicates when multiple EMS write to the same row of a DO at the same time." Changes in SOA Human Task Flow (Run-Time) for Fusion Applications | Jack Desai Oracle Fusion Middleware A-Team blogger Jack Desai shares a troubleshooting tip.

• T-SQL Tuesday #025 &ndash; CHECK Constraint Tricks

  - by Most Valuable Yak (Rob Volk)

  Allen White (blog | twitter), marathoner, SQL Server MVP and presenter, and all-around awesome author is hosting this month's T-SQL Tuesday on sharing SQL Server Tips and Tricks.  And for those of you who have attended my Revenge: The SQL presentation, you know that I have 1 or 2 of them.  You'll also know that I don't recommend using anything I talk about in a production system, and will continue that advice here…although you might be sorely tempted.  Suffice it to say I'm not using these examples myself, but I think they're worth sharing anyway. Some of you have seen or read about SQL Server constraints and have applied them to your table designs…unless you're a vendor ;)…and may even use CHECK constraints to limit numeric values, or length of strings, allowable characters and such.  CHECK constraints can, however, do more than that, and can even provide enhanced security and other restrictions. One tip or trick that I didn't cover very well in the presentation is using constraints to do unusual things; specifically, limiting or preventing inserts into tables.  The idea was to use a CHECK constraint in a way that didn't depend on the actual data: -- create a table that cannot accept data CREATE TABLE dbo.JustTryIt(a BIT NOT NULL PRIMARY KEY, CONSTRAINT chk_no_insert CHECK (GETDATE()=GETDATE()+1)) INSERT dbo.JustTryIt VALUES(1)   I'll let you run that yourself, but I'm sure you'll see that this is a pretty stupid table to have, since the CHECK condition will always be false, and therefore will prevent any data from ever being inserted.  I can't remember why I used this example but it was for some vague and esoteric purpose that applies to about, maybe, zero people.  I come up with a lot of examples like that. However, if you realize that these CHECKs are not limited to column references, and if you explore the SQL Server function list, you could come up with a few that might be useful.  I'll let the names describe what they do instead of explaining them all: CREATE TABLE NoSA(a int not null, CONSTRAINT CHK_No_sa CHECK (SUSER_SNAME()<>'sa')) CREATE TABLE NoSysAdmin(a int not null, CONSTRAINT CHK_No_sysadmin CHECK (IS_SRVROLEMEMBER('sysadmin')=0)) CREATE TABLE NoAdHoc(a int not null, CONSTRAINT CHK_No_AdHoc CHECK (OBJECT_NAME(@@PROCID) IS NOT NULL)) CREATE TABLE NoAdHoc2(a int not null, CONSTRAINT CHK_No_AdHoc2 CHECK (@@NESTLEVEL>0)) CREATE TABLE NoCursors(a int not null, CONSTRAINT CHK_No_Cursors CHECK (@@CURSOR_ROWS=0)) CREATE TABLE ANSI_PADDING_ON(a int not null, CONSTRAINT CHK_ANSI_PADDING_ON CHECK (@@OPTIONS & 16=16)) CREATE TABLE TimeOfDay(a int not null, CONSTRAINT CHK_TimeOfDay CHECK (DATEPART(hour,GETDATE()) BETWEEN 0 AND 1)) GO -- log in as sa or a sysadmin server role member, and try this: INSERT NoSA VALUES(1) INSERT NoSysAdmin VALUES(1) -- note the difference when using sa vs. non-sa -- then try it again with a non-sysadmin login -- see if this works: INSERT NoAdHoc VALUES(1) INSERT NoAdHoc2 VALUES(1) GO -- then try this: CREATE PROCEDURE NotAdHoc @val1 int, @val2 int AS SET NOCOUNT ON; INSERT NoAdHoc VALUES(@val1) INSERT NoAdHoc2 VALUES(@val2) GO EXEC NotAdHoc 2,2 -- which values got inserted? SELECT * FROM NoAdHoc SELECT * FROM NoAdHoc2   -- and this one just makes me happy :) INSERT NoCursors VALUES(1) DECLARE curs CURSOR FOR SELECT 1 OPEN curs INSERT NoCursors VALUES(2) CLOSE curs DEALLOCATE curs INSERT NoCursors VALUES(3) SELECT * FROM NoCursors   I'll leave the ANSI_PADDING_ON and TimeOfDay tables for you to test on your own, I think you get the idea.  (Also take a look at the NoCursors example, notice anything interesting?)  The real eye-opener, for me anyway, is the ability to limit bad coding practices like cursors, ad-hoc SQL, and sa use/abuse by using declarative SQL objects.  I'm sure you can see how and why this would come up when discussing Revenge: The SQL.;) And the best part IMHO is that these work on pretty much any version of SQL Server, without needing Policy Based Management, DDL/login triggers, or similar tools to enforce best practices. All seriousness aside, I highly recommend that you spend some time letting your mind go wild with the possibilities and see how far you can take things.  There are no rules! (Hmmmm, what can I do with rules?) #TSQL2sDay

• Unable to add users to Microsoft Dynamics CRM 4.0 after database restore

  - by Wes Weeks

  Working with a client in our Multi-tenant CRM environment who was doing a database migration into CRM and as part of the process, a backup of their Organization_MSCRM database was taken just prior to starting the migration in case it needed to be restored and run a second time. In this case it did, so I restored the database and let the client know he should be good to go.  A few hours later I received a call that they were unable to add some new users, they would appear as available when using the add multiple user wizard, but anyone added would not be added to CRM.  It was also disucussed that these users had been added to CRM initally AFTER the database backup had been taken. I turned on tracing and tried to add the users through both the single user form and multiple user interface and was unable to do so.  The error message in the logs wasn't much help: Unexpected error adding user [email protected]: Microsoft.Crm.CrmException: INVALID_WRPC_TOKEN: Validate WRPC Token: WRPCTokenState=Invalid, TOKEN_EXPIRY=4320, IGNORE_TOKEN=False Searching on Google or bing didn't offer any assitance.  Apparently not a very common problem, or no one has been able to resolve. I did some searching in the MSCRM_CONFIG database and found that their are several user tables there and after getting my head around the structure found that there were enties here for users that were not part of the restored DB.  It seems that new users are added to both the Orgnaization_MSCRM and MSCRM_CONFIG and after the restore these were out of sync. I needed to remove the extra entries in order to address.  Restoring the MSCRM_CONFIG database was not an option as other clients could have been adding users at this point and to restore would risk breaking their instances of CRM.  Long story short, I was finally able to generate a script to remove the bad entries and when I tried to add users again, I was succesful.  In case someone else out there finds themselves in a similar situation, here is the script I used to delete the bad entries. DECLARE @UsersToDelete TABLE (   UserId uniqueidentifier )   Insert Into @UsersToDelete(UserId) Select UserId from [MSCRM_CONFIG].[dbo].[SystemUserOrganizations] Where CrmuserId Not in (select systemuserid from Organization_MSCRM.dbo.SystemUserBase) And OrganizationId = '00000000-643F-E011-0000-0050568572A1' --Id From the Organization table for this instance   Delete From [MSCRM_CONFIG].[dbo].[SystemUserAuthentication]   Where UserId in (Select UserId From @UsersToDelete)   Delete From [MSCRM_CONFIG].[dbo].[SystemUserOrganizations] Where UserId in (Select UserId From @UsersToDelete)   Delete From [MSCRM_CONFIG].[dbo].[SystemUser] Where Id in (Select UserId From @UsersToDelete)

• Tip on Reusing Classes in Different .NET Project Types

  - by psheriff

  All of us have class libraries that we developed for use in our projects. When you create a .NET Class Library project with many classes, you can use that DLL in ASP.NET, Windows Forms and WPF applications. However, for Silverlight and Windows Phone, these .NET Class Libraries cannot be used. The reason is Silverlight and Windows Phone both use a scaled down version of .NET and thus do not have access to the full .NET framework class library. However, there are many classes and functionality that will work in the full .NET and in the scaled down versions that Silverlight and Windows Phone use.Let’s take an example of a class that you might want to use in all of the above mentioned projects. The code listing shown below might be something that you have in a Windows Form or an ASP.NET application. public class StringCommon{  public static bool IsAllLowerCase(string value)  {    return new Regex(@"^([^A-Z])+$").IsMatch(value);  }   public static bool IsAllUpperCase(string value)  {    return new Regex(@"^([^a-z])+$").IsMatch(value);  }} The StringCommon class is very simple with just two methods, but you know that the System.Text.RegularExpressions namespace is available in Silverlight and Windows Phone. Thus, you know that you may reuse this class in your Silverlight and Windows Phone projects. Here is the problem: if you create a Silverlight Class Library project and you right-click on that project in Solution Explorer and choose Add | Add Existing Item… from the menu, the class file StringCommon.cs will be copied from the original location and placed into the Silverlight Class Library project. You now have two files with the same code. If you want to change the code you will now need to change it in two places! This is a maintenance nightmare that you have just created. If you then add this to a Windows Phone Class Library project, you now have three places you need to modify the code! Add As LinkInstead of creating three separate copies of the same class file, you want to leave the original class file in its original location and just create a link to that file from the Silverlight and Windows Phone class libraries. Visual Studio will allow you to do this, but you need to do one additional step in the Add Existing Item dialog (see Figure 1). You will still right mouse click on the project and choose Add | Add Existing Item… from the menu. You will still highlight the file you want to add to your project, but DO NOT click on the Add button. Instead click on the drop down portion of the Add button and choose the “Add As Link” menu item. This will now create a link to the file on disk and will not copy the file into your new project. Figure 1: Add as Link will create a link, not copy the file over. When this linked file is added to your project, there will be a different icon next to that file in the Solution Explorer window. This icon signifies that this is a link to a file in another folder on your hard drive.   Figure 2: The Linked file will have a different icon to show it is a link. Of course, if you have code that will not work in Silverlight or Windows Phone -- because the code has dependencies on features of .NET that are not supported on those platforms – you  can always wrap conditional compilation code around the offending code so it will be removed when compiled in those class libraries. SummaryIn this short blog entry you learned how to reuse one of your class libraries from ASP.NET, Windows Forms or WPF applications in your Silverlight or Windows Phone class libraries. You can do this without creating a maintenance nightmare by using the “Add a Link” feature of the Add Existing Item dialog. Good Luck with your Coding,Paul Sheriff ** SPECIAL OFFER FOR MY BLOG READERS **Visit http://www.pdsa.com/Event/Blog for a free video on Silverlight entitled Silverlight XAML for the Complete Novice - Part 1.

• What to do if I am working on a language that I don't like

  - by Sayem Ahmed

  Hi there, I really don't know if this is the right place to ask this question, but if it isn't, then I guess someone will notify. Anyway, I am working in a software development farm which is currently using PowerBuilder to develop a mid-size ERP solution. The work environment and company management are so great that it may be the best in the whole Bangladesh. Only problem is the technology that are currently being used, which is this PowerBuilder. Now I am a guy who tends to prefer modern development technologies, like DI containers, ORM, TDD, JQuery etc. PowerBuilder is a great tool too, but I couldn' like the application techniques used to build PB applications. These techniques are so inheritance-dependent that many a times these create a great deal of sufferings. I remember two days ago I had to change some processing logic in a core user object and as a result I had to test and re-test all the forms that the application have(apparently, there are almost 20 forms there, each of them with 3-4 kinds of functionalities). Also, learning PB is tough, because online material on this thing is very, very low. I can't afford to read all the documentation that PB provide because I have hard deadlines on the work that I have to do. Another thing with PB is that applications tend to rely on business logic that are implemented on databases which causes debugging to be a nightmare. As a result, I don't feel motivated enough to work in this IDE/System/Framework (or whatever) anymore. My productivity has greatly decreased, and I am not delivering quality code. I think I have the following options available to me - Remain in the current job, keep delivering worse code and let my productivity decrease day by day, taking salaries and bonuses but not delivering quality codes/doing my job the way I should, Search for a new job. At this point number 2 seems a good option, but there are also some issues. As I mentioned before, our management may be the best in the country. Our company owner is himself a software developer with 24 years of experience in software development. He is currently our Team Leader and System Analyst. He is by far the greatest manager and boss I have ever seen. He understands developer's mentality very well(as he IS himself a developer). He is also a great, kind and generous guy. Our company is only a start-up company with 10 developers. Among them, only 3-4 people knows about the business logic behind the ERP, and I am one of them. If I switch my current job, it may hamper the development of this product which I really don't want. I couldn't decide what to do in this situation, so I turned to the community for advice.

• Securing User Account Details with MySQL

  - by Antoinette O'Sullivan

  Keeping user account details secure is always at the forefront of a Database Administrator's mind. However, users want to get up and running as soon as possible without complex login procedures. You can learn more about this and many other topics in the MySQL for Database Administrator course. For example, MySQL 5.6.6 introduced a new utility: mysql_config_editor, which makes secure access via MySQL client applications much easier to establish, while still providing a good measure of security. The mysql_config_editor stores a user's authentication details in an encrypted login file called mylogin.cnf. This login file is readable and writable for the user who invokes the utility, and invisible to everyone else. You can use it to collect all your hard-to-remember server locations and paswords safe in the knowledge that your passwords are never invoked using clear text. The MySQL for Database Administrators course is a 5-day instructor-led course which is available as a: Training-on-Demand: Start training within 24 hours of registration, following lecture material at your own pace through streaming video and booking time on a lab environment to suit your schedule. Live-Virtual Event: Attend a live event from your own desk, choosing from a selection of events on the schedule to suit different timezones.
