• Graphical Error During Installation of Ubuntu 13.10 32bit

  - by user172353

  In trying to install the latest version of Ubuntu, I made a bootable USB and proceeded to give it a shot. As it loaded, the upper half of the screen displayed staticy, multi-colored horizontal lines, but continued to boot into the installer. The installer appeared to be functional using the keyboard, but I was unable to proceed as the graphical display was a mismatched mosaic of the proper screen with no visible cursor. I'll try to edit in a photo later. Attempting the exact same USB on a different device (an old Asus Eee 1005HA) gave no such error and installed without a hitch.

• Error: The base type 'System.Web.UI.MasterPage' is not allowed for this page

  - by Patrick Olurotimi Ige

  I came across this error when i was trying to ajaxify my sharepoint site. After adding the AjaxifyMoss from the codeplex  developed by Richard Finn. And tried loading my site i got the error Error: The base type 'System.Web.UI.MasterPage' is not allowed for this page So  i decided to check the web.config and i noticed the SafeControl tag doesn't have the .Net 2.0 assembly included despite the fact i added both vsersios 2.0 and 3.5. Its possible the.Net  3.5 assebply overwrote the 2.0. Anyway after i added the below which is the 2.0 verison       <SafeControl Assembly="System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" Namespace="System.Web.UI" TypeName="*" Safe="True" AllowRemoteDesigner="True" />  And refreshed my page.

• .co.uk targeted for google.co.uk .com targeted for google.com

  - by Higgs Boson

  We've had a website running on a .co.uk domain for some years, this domain is listed in the SERPS for our brand on both google.co.uk and google.com. We get little traffic from anywhere other than the UK because the website is targeted at the UK market with specific UK keywords. This is great, however we recently purchased the .com domain with the intention of producing a second version of the website targeted to the United States with US specific keywords i.e. targeting and moving in to the US marketplace. We have used Google webmaster tools to set the geographic target for the .com domain to be the US. I think I was expecting ONLY the .com site to show up when searching google.com and only the .co.uk site to show up when searching google.co.uk. However when we search google.com for our 'brand' the .co.uk site is listed in the SERPS. We would prefer the .com to appear in the SERPS on google.com. Is there anything we can do?

• New Article: SharePoint 2010 for Developers &ndash; Whats new?

  - by Sahil Malik

  SharePoint 2010 Training: more information This is an nice overview/beginners article about what is new in SharePoint 2010 from purely a developer point of view. Excerpt - “In some ways SharePoint 2007 was a brand new incarnation of the SharePoint product. For the very first time, ASP.NET 2.0 was applied properly to the product. Things such as master pages, membership providers, sitemap providers etc. were used heavily in SharePoint. As a result, SharePoint 2007 got a whole new developer story to it. But in some ways it was a first version of a big product, so the development story left us wanting for more. Wanting for more because in some ways the API wasn’t ideal, and most certainly the development tools were somewhere between non-existent to bad. Diagnosing SharePoint errors was another frustrating story many have endured. What has changed in SharePoint 2010? Let’s find out.” Read full article ....

• Predicting Likelihood of Click with Multiple Presentations

  - by Michel Adar

  When using predictive models to predict the likelihood of an ad or a banner to be clicked on it is common to ignore the fact that the same content may have been presented in the past to the same visitor. While the error may be small if the visitors do not often see repeated content, it may be very significant for sites where visitors come repeatedly. This is a well recognized problem that usually gets handled with presentation thresholds – do not present the same content more than 6 times. Observations and measurements of visitor behavior provide evidence that something better is needed. Observations For a specific visitor, during a single session, for a banner in a not too prominent space, the second presentation of the same content is more likely to be clicked on than the first presentation. The difference can be 30% to 100% higher likelihood for the second presentation when compared to the first. That is, for example, if the first presentation has an average click rate of 1%, the second presentation may have an average CTR of between 1.3% and 2%. After the second presentation the CTR stays more or less the same for a few more presentations. The number of presentations in this plateau seems to vary by the location of the content in the page and by the visual attraction of the content. After these few presentations the CTR starts decaying with a curve that is very well approximated by an exponential decay. For example, the 13th presentation may have 90% the likelihood of the 12th, and the 14th has 90% the likelihood of the 13th. The decay constant seems also to depend on the visibility of the content. Modeling Options Now that we know the empirical data, we can propose modeling techniques that will correctly predict the likelihood of a click. Use presentation number as an input to the predictive model Probably the most straight forward approach is to add the presentation number as an input to the predictive model. While this is certainly a simple solution, it carries with it several problems, among them: If the model learns on each case, repeated non-clicks for the same content will reinforce the belief of the model on the non-clicker disproportionately. That is, the weight of a person that does not click for 200 presentations of an offer may be the same as 100 other people that on average click on the second presentation. The effect of the presentation number is not a customer characteristic or a piece of contextual data about the interaction with the customer, but it is contextual data about the content presented. Models tend to underestimate the effect of the presentation number. For these reasons it is not advisable to use this approach when the average number of presentations of the same content to the same person is above 3, or when there are cases of having the presentation number be very large, in the tens or hundreds. Use presentation number as a partitioning attribute to the predictive model In this approach we essentially build a separate predictive model for each presentation number. This approach overcomes all of the problems in the previous approach, nevertheless, it can be applied only when the volume of data is large enough to have these very specific sub-models converge.

• [MISC GEEKERY] Lucid Lynx to Come Loaded with Ubuntu One Music Store

  - by Vivek

  Ubuntu 10.04 (code name Lucid Lynx) will come loaded with the Ubuntu One music store. Rhythmbox will have the Ubuntu One music store integrated in it. It’ll also allow users to download purchased music to their local machine. Ubuntu One Music Store Users will be able to access Ubuntu One music store from the sidebar of Rhythmbox. The music store is a web page that opens in the Rhythmbox player. There are albums listed on the home page of the Ubuntu One music store page. Ubuntu One music store is powered by 7digital, which is a leading digital B2B media delivery company based in London and operating globally. Canonical, the company behind Ubuntu, has partnered with 7digital to bring the music store to it’s users, integrating it with Rhythmbox and it’s cloud storage service UbuntuOne which was launched last year. The home screen of the Ubuntu One music store displays popular albums and functionality to browse and search. You can search for Artists, Tracks, Albums, or a combination of all three. Users will also be able to browse the store alphabetically, or based on different music genres. Once you select a specific artist, all their available albums are arranged in a grid. Once an album is selected, you’ll will be able to download specific songs or the whole album. You’ll also be allowed to preview different songs for 60 seconds. You’ll be able to buy tracks using a credit card or with PayPal. The purchased tracks will be visible under Library \ Purchased from Ubuntu One. The downloaded tracks are also synced with your UbuntuOne account. This means that you’ll be able to access your tracks from any where on the web. The default UbuntuOne account comes with 2 GB free storage, however, you can also purchase additional space if you need it.   All the music is in mp3 format which is not supported by default in Ubuntu. However, you can get mp3 playback functionality using GStreamer multimedia framework. Conclusion All in all the Ubuntu One music store is a positive move to enhance the user experience and also increase the popularity of Canonical in bringing Ubuntu closer to regular users. This would also provide Canonical to make some revenue in collaboration with 7digital.

• [SQLServer JDBC Driver][SQLServer]Could not find stored procedure 'master..xp_jdbc_open2'.

  - by Vijaya Moderator -Oracle

  When connecting to MS SQL Server Database via Weblogic Datasource and using XA jdbc driver, the following error is thrown. <Jun 3, 2014 5:16:49 AM PDT> <Error> <Console> <BEA-240003> <Console encountered the following error java.sql.SQLException: [FMWGEN][SQLServer JDBC Driver][SQLServer]Could not find stored procedure 'master..xp_jdbc_open2'. at weblogic.jdbc.sqlserverbase.ddb_.b(Unknown Source)at weblogic.jdbc.sqlserverbase.ddb_.a(Unknown Source)at weblogic.jdbc.sqlserverbase.ddb9.b(Unknown Source)at weblogic.jdbc.sqlserverbase.ddb9.a(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddr.v(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddr.a(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddq.a(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddr.a(Unknown Source)at weblogic.jdbc.sqlserver.ddj.m(Unknown Source)at weblogic.jdbc.sqlserverbase.ddel.e(Unknown Source)at weblogic.jdbc.sqlserverbase.ddel.a(Unknown Source)  The cause behind the issue is that  the MS SQL Server was not installed with the Stored procedures to enable JTA/XA Solution To connect to SQL Server via XA Driver from WLS Datasource you need to install Stored Procedures for JTATo use JDBC distributed transactions through JTA, your system administrator should use the following procedure to install Microsoft SQL Server JDBC XA procedures. This procedure must be repeated for each MS SQL Server installation that will be involved in a distributed transaction.To install stored procedures for JTA:1. Copy the appropriate sqljdbc.dll and instjdbc.sql files from the WL_HOME\server\lib directory to the SQL_Server_Root/bin directory of the MS SQL Server database server, where WL_HOME is the directory in which WebLogic server is installed, typically c:\Oracle\Middleware\wlserver_10.x.  Note:  If you are installing stored procedures on a database server with multiple Microsoft SQL Server instances, each running SQL Server instance must be able to locate the sqljdbc.dll file.Therefore the sqljdbc.dll file needs to be anywhere on the global PATH or on the application-specific path. For the application-specific path, place the sqljdbc.dll file into the :\Program Files\Microsoft SQL Server\MSSQL$\Binn directory for each instance. 2. From the database server, use the ISQL utility to run the instjdbc.sql script. As a precaution, have your system administrator back up the master database before running instjdbc.sql. At a command prompt, use the following syntax to run instjdbc.sql:  ISQL -Usa -Psa_password -Sserver_name -ilocation\instjdbc.sql  where:  sa_password is the password of the system administrator.  server_name is the name of the server on which SQL Server resides.  location is the full path to instjdbc.sql. (You copied this script to the SQL_Server_Root/bin directory in step 1.)  The instjdbc.sql script generates many messages. In general, these messages can be ignored; however, the system administrator should scan the output for any messages that may indicate an execution error. The last message should indicate that instjdbc.sql ran successfully. The script fails when there is insufficient space available in the master database to store the JDBC XA procedures or to log changes to existing procedures.

• DirectX11 Swap Chain Format

  - by Nathan

  I was wondering if anyone could elaborate any further on something thats been bugging be me. In DirectX9 the main supported back buffer formats were D3DFMT_X8R8B8G8 and D3DFMT_A8R8G8B8 (Both being BGRA in layout). http://msdn.microsoft.com/en-us/library/windows/desktop/bb174314(v=vs.85).aspx With the initial version of DirectX10 their was no support for BGRA and all the textbooks and online tutorials recommend DXGI_FORMAT_R8G8B8A8_UNORM (being RGBA in layout). Now with DirectX11 BGRA is supported again and it seems as if microsoft recommends using a BGRA format as the back buffer format. http://msdn.microsoft.com/en-us/library/windows/apps/hh465096.aspx Is their any suggestions or are their performance implications of using one or the other. (I assume not as obviously by specifying the format of the underlying resource the runtime will handle what bits your passing through and than infer how to utilise them based on the format). Any feedback is appreciated.

• Create Chemistry Equations and Diagrams in Word

  - by Matthew Guay

  Microsoft Word is a great tool for formatting text, but what if you want to insert a chemistry formula or diagram?  Thanks to a new free add-in for Word, you can now insert high-quality chemistry formulas and diagrams directly from the Ribbon in Word. Microsoft’s new Education Labs has recently released the new Chemistry Add-in for Word 2007 and 2010.  This free download adds support for entering and editing chemistry symbols, diagrams, and formulas using the standard XML based Chemical Markup Language.  You can convert any chemical name, such as benzene, or formula, such as H2O, into a chemical diagram, standard name, or formula.  Whether you’re a professional chemist, just taking chemistry in school, or simply curious about the makeup of Citric Acid, this add-in is an exciting way to bring chemistry to your computer. This add-in works great on Word 2007 and 2010, including the 64 bit version of Word 2010.  Please note that the current version is still in beta, so only run it if you are comfortable running beta products. Getting Started Download the Chemistry add-in from Microsoft Education Labs (link below), and unzip the file.  Then, run the ChemistryAddinforWordBeta2.Setup.msi. It may inform you that you need to install the Visual Studio Tools for Office 3.0.  Simply click Yes to download these tools. This will open the download in your default browser.  Simply click run, or save and then run it when it is downloaded. Now, click next to install the Visual Studio Tools for Office as usual. When this is finished, run the ChemistryAddinforWordBeta2.Setup.msi again.  This time, you can easily install it with the default options. Once it’s finished installing, open Word to try out the Chemistry Add-in.  You will be asked if you want to install this customization, so click Install to enable it. Now you will have a new Chemistry tab in your Word ribbon.  Here’s the ribbon in Word 2010… And here it is in Word 2007.   Using the Chemistry Add-in It’s very easy to insert nice chemistry diagrams and formulas in Word with the Chemistry add-in.  You can quickly insert a premade diagram from the Chemistry Gallery: Or you can insert a formula from file.  Simply click “From File” and choose any Chemical Markup Language (.cml) formatted file to insert the chemical formula. You can also convert any chemical name to it’s chemical form.  Simply select the word, right-click, select “Convert to Chemistry Zone” and then click on its name. Now you can see the chemical form in the sidebar if you click the Chemistry Navigator button, and can choose to insert the diagram into the document.  Some chemicals will automatically convert to the diagram in the document, while others simply link to it in the sidebar.  Either way, you can display exactly what you want. You can also convert a chemical formula directly to it’s chemical diagram.  Here we entered H2O and converted it to Chemistry Zone: This directly converted it to the diagram directly in the document. You can click the Edit button on the top, and from there choose to either edit the 2D model of the chemical, or edit the labels.

• Renewed as MVP

  - by Sahil Malik

  Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). It is with great humbleness and honor that I accept Microsoft’s MVP award for 2010. This will be my .. I forget how many years, as an MVP. So suffice to say, I was a lot younger when I first got the MVP award, but also the excitement never dies. Don’t get me wrong, I’m still young, foolish and weird :). (and good looking, might I add) I’d like to share a few things with you on what I have learnt being a part of this very prestigious program that I am so unworthy of. Never aim to be an MVP. Let it be a consequence of what you already are. Always be down to earth, just because you’re an MVP doesn’t mean you’re better than anyone else. The biggest reward of the MVP program, yes much bigger than the free top notch MSDN subscription, is the amazing interaction you will have with other fellow MVPs, and incredibly smart people in the community in general. Get involved in the community, for your own sake! You will learn so much from your peers, it is a very very rewarding experience. Learn, Learn and Learn! Never under estimate the power of knowledge. Both technical and otherwise. I thank each one of you for all the attention you have given me over the past many years. And a very special thanks to my MVP lead, Melissa Travers, and my previous MVP lead Rafael Munoz (who isn’t with Microsoft anymore, but I am sure is kicking butt wherever he is). We are truly entering a very very exciting time in the technology space. Both Google and Apple are challenging Microsoft, forcing Microsoft to innovate at a pace like never before. Microsoft is coming out with an incredible amount of good, new and exciting stuff. Windows Mobile 7, Azure, .NET 4.0, Silverlight 4.0, IE9, and of course SharePoint 2010. The level of innovation in the tech industry is simply unprecedented. A truly exciting time for anyone who lives, breathes, sleeps and dreams of technology even when awake! (Like me!) As you know, I’ve been working on my SP2010 book lately. I’m happy to also inform that the book is DONE. WOOHOO!! :). So this means, I’ll have more time to blog, and cause more trouble in general. Once again! THANK YOU! Comment on the article ....

• Fundtech’s Global PAYplus Achieves Oracle Exadata and Oracle Exalogic Optimized Status

  - by Javier Puerta

  Fundtech, a leader in global transaction banking solutions, has announced  that Global PAYplus® – Services Platform (GPP-SP) version 4 has achieved Oracle Exadata Optimized and Oracle Exalogic Optimized status. (Read full announcement here) "GPP-SP testing was done in the third quarter of 2012 in the Oracle Exastack Lab located in the Oracle Solution Center in Linlithgow, Scotland. It showed that an integrated solution can result in a highly streamlined installation, enabling reduced cost of evaluation, acquisition and ownership. Highlights of the transaction processing test are as follows: 9.3 million Mass Payments per hour 5.7 million Single Payments per hour The test found that the optimized combination of GPP-SP running on Oracle Exadata Database Machine and Oracle Exalogic Elastic Cloud is able to increase transactions per second (TPS) output per core, and able to reduce total cost of ownership (TCO). The volumes achieved were using only 25% of Exadata/Exalogic processing capacity".

• Introducing Microsoft SQL Server 2008 R2 - Business Intelligence Samples

  - by smisner

  On April 14, 2010, Microsoft Press (blog | twitter) released my latest book, co-authored with Ross Mistry (twitter), as a free ebook download - Introducing Microsoft SQL Server 2008 R2. As the title implies, this ebook is an introduction to the latest SQL Server release. Although you'll find a comprehensive review of the product's features in this book, you will not find the step-by-step details that are typical in my other books. For those readers who are interested in a more interactive learning experience, I have created two samples file for download: IntroSQLServer2008R2Samples project Sales Analysis workbook Here's a recap of the business intelligence chapters and the samples I used to generate the screen shots by chapter: Chapter 6: Scalable Data Warehousing covers a new edition of SQL Server, Parallel Data Warehouse. Understandably, Microsoft did not ship me the software and hardware to set up my own Parallel Data Warehouse environment for testing purposes and consequently you won't see any screenshots in this chapter. I received a lot of information and a lot of help from the product team during the development of this chapter to ensure its technical accuracy. Chapter 7: Master Data Services is a new component in SQL Server. After you install Master Data Services (MDS), which is a separate installation from SQL Server although it's found on the same media, you can install sample models to explore (which is what I did to create screenshots for the book). To do this, you deploying packages found at \Program Files\Microsoft SQL Server\Master Data Services\Samples\Packages. You will first need to use the Configuration Manager (in the Microsoft SQL Server 2008 R2\Master Data Services program group) to create a database and a Web application for MDS. Then when you launch the application, you'll see a Getting Started page which has a Deploy Sample Data link that you can use to deploy any of the sample packages. Chapter 8: Complex Event Processing is an introduction to another new component, StreamInsight. This topic was way too large to cover in-depth in a single chapter, so I focused on information such as architecture, development models, and an overview of the key sections of code you'll need to develop for your own applications. StreamInsight is an engine that operates on data in-flight and as such has no user interface that I could include in the book as screenshots. The November CTP version of SQL Server 2008 R2 included code samples as part of the installation, but these are not the official samples that will eventually be available in Codeplex. At the time of this writing, the samples are not yet published. Chapter 9: Reporting Services Enhancements provides an overview of all the changes to Reporting Services in SQL Server 2008 R2, and there are many! In previous posts, I shared more details than you'll find in the book about new functions (Lookup, MultiLookup, and LookupSet), properties for page numbering, and the new global variable RenderFormat. I will confess that I didn't use actual data in the book for my discussion on the Lookup functions, but I did create real reports for the blog posts and will upload those separately. For the other screenshots and examples in the book, I have created the IntroSQLServer2008R2Samples project for you to download. To preview these reports in Business Intelligence Development Studio, you must have the AdventureWorksDW2008R2 database installed, and you must download and install SQL Server 2008 R2. For the map report, you must execute the PopulationData.sql script that I included in the samples file to add a table to the AdventureWorksDW2008R2 database. The IntroSQLServer2008R2Samples project includes the following files: 01_AggregateOfAggregates.rdl to illustrate the use of embedded aggregate functions 02_RenderFormatAndPaging.rdl to illustrate the use of page break properties (Disabled, ResetPageNumber), the PageName property, and the RenderFormat global variable 03_DataSynchronization.rdl to illustrate the use of the DomainScope property 04_TextboxOrientation.rdl to illustrate the use of the WritingMode property 05_DataBar.rdl 06_Sparklines.rdl 07_Indicators.rdl 08_Map.rdl to illustrate a simple analytical map that uses color to show population counts by state PopulationData.sql to provide the data necessary for the map report Chapter 10: Self-Service Analysis with PowerPivot introduces two new components to the Microsoft BI stack, PowerPivot for Excel and PowerPivot for SharePoint, which you can learn more about at the PowerPivot site. To produce the screenshots for this chapter, I created the Sales Analysis workbook which you can download (although you must have Excel 2010 and the PowerPivot for Excel add-in installed to explore it fully). It's a rather simple workbook because space in the book did not permit a complete exploration of all the wonderful things you can do with PowerPivot. I used a tutorial that was available with the CTP version as a basis for the report so it might look familiar if you've already started learning about PowerPivot. In future posts, I'll continue exploring the new features in greater detail. If there's any special requests, please let me know!

• 2010 Collaboration Summit Impressions

  - by Elena Zannoni

  It's a bit late, but there you have it anyway. April 14 to 16 I attended the Linux Foundation Collaboration Summit in SFO. I was running two tracks, one on tracing and one on tools. You can see the tracks and the slides here: http://events.linuxfoundation.org/events/collaboration-summit/slides I was pretty busy both days, Thursday with a whole day tracing track, Friday with a half day toolchain track. The sessions were well attended, the rooms were full, with people spilling in the hallways. Some new things were presented, like Kernelshark, by Steve Rostedt, a GUI (yes, believe it or not, a GUI) written in GTK. It is very nice, showing a timeline for traced kernel events, and you can zoom in and filter at will. It works on the latest kernels, and it requires some new things/fixes in GTK. I don't recall exactly what version of GTK though. Dominique Toupin from Ericsson presented something about user requirements for tracing. Mostly though about who's who in the embedded world, and eclipse. Masami and Mathieu presented an update on their work. See their slides. The interesting thing to me was of course the new version of uprobes w/o underlying utrace presented by Jim Keniston. At the end of the session we had a discussion about the future of utrace. Roland wasn't there, butTom Tromey (also from RedHat) collected the feedback. Basically we are at a standstill now that utrace has been rejected yet again. There wasn't much advise that anybody could give, except jokingly, we decided that the only way in is to make it a part of perf events. There needs to be another refactoring, but most of all, this "killer app" that would be enabled because of utrace hasn't materialized yet. We think that having a good debugging story on Linux is enough of a killer app, for instance allowing multiple tracers, and not relying on SIGCHLD etc. I think this wasn't completely clear to the kernel community. Trying to achieve debugging via a gdb stub inside the kernel interfacing to utrace and that is controlled via the gdb remote protocol also lost its appeal (thankfully, since the gdb remote protocol is archaic). Somebody would have to be creative in how to submit utrace. It doesn't have to be called utrace (it was really a random choice, for lack of a letter that was not already used in front of the word "trace"). So basically, I think the ideas behind utrace are sound, and the necessity of a new interface is acknowledged. But I believe the integration/submission process with the kernel folks has to restart from scratch, clean slate. We'll see. There are many conferences and meetings coming up in the near future where things can be discussed further. On the second day, Friday, we had the tools talks. It was interesting to observe the more "kernel" oriented people's behavior towards the gcc etc community. The first talk was by Mark Mitchell, about Gcc and its new plugin architecture. After that, Paolo talked about the new C++1x standard, which will be finalized in 2011. Many features are already implemented in the libstdc++ library and gcc and usable today. We had a few minutes (really, the half day track was quite short) where Bradley Kuhn from the Software Freedom Law Center explained the GPLv3 exception for gcc (due to the new gcc plugin architecture and the availability of the intermediate results from the compilation, which is a new thing). I will not try to explain, but basically you cannot take the result of the preprocessing and then use that in your own proprietary compiler. After, we had a talk by Ian Taylor about the new Gold linker. One good thing in that area is that they are trying to make gold the new default linker (for instance Fedora will use gold as the distro linker). However gold is very different from binutils' old linker. It doesn't use a linker script, for instance. The kernel has been linked with gold many times as an exercise (the ground work was done by Kris Van Hees), but this needs to be constantly tested/monitored because the kernel linker script is very complex, and uses esoteric features (Wenji is now monitoring that each kernel RC can be built with gold). It was positive that people are now aware of gold and the need for it to be ported to more architectures. It seems that the porting is very easy, with little arch dependent code. Finally Tom Tromey presented about gdb and the archer project. Archer is a development branch of gdb mostly done by RedHat, where they are focusing on better c++ printing, c++ expression parsing, and plugins. The archer work is merged regularly in the gdb mainline. In general it was a good conference. I did miss most of the first day, because that's when I flew in. But I caught a couple of talks. Nothing earth shattering, except for Google giving each person registered a free Android phone. Yey.

• .NET Framework 4.0 mysteriously loses track of System.EnterpriseServices

  - by Lorin Thwaits

  The GAC in .NET 4.0 is cut into two parts now -- one half for .NET Framework 2.0 stuff, and the other for v4.0 stuff. When compiling any project, targeting .NET 2.0, 3.5, or what have you, this annoying error may pop up: Could not load file or assembly 'System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. In that case, open a run box and perform this copy command: xcopy %ProgramFiles%\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.EnterpriseServices.dll %windir%\Microsoft.NET\assembly\GAC_32\System.EnterpriseServices\v4.0_4.0.0.0__b03f5f7f11d50a3a /e This reconstructs the proper portion of the GAC for that one missing file.

• TFS 2010 and the missing Area & Iterations (stale data) Issue

  - by andresv

  The symptom is this: you change some area or iteration in a TFS Project, but the change is not reflected (or updated) in VS or any other TFS Client. Well, it happens that TFS now has some clever caching mechanisms that need to be updated when you make a change like this, and those changes are propagated by some scheduled jobs TFS is continuously running in the Application Tier.  So, you you get this behavior, please check (and possibly restart) the "Visual Studio Team Foundation Background Job Agent" service. In my case, this service was logging a very odd "Object Reference Not Set" into the Windows Event Log, and a simple restart fixed it. Hope this is fixed by RTM...   (we are using the RC version). And by the way, if the job agent is broken there are some other things that stops working like email notifications. Best regards, Andrés G Vettori, CTO, VMBC

• Knockoutjs - stringify to handling observables and custom events

  - by Renso

  Goal: Once you viewmodel has been built and populated with data, at some point it goal of it all is to persist the data to the database (or some other media). Regardless of where you want to save it, your client-side viewmodel needs to be converted to a JSON string and sent back to the server. Environment considerations: jQuery 1.4.3+ Knockoutjs version 1.1.2   How to: So let’s set the stage, you are using Knockoutjs and you have a viewmodel with some Knockout dependencies. You want to make sure it is in the proper JSON format and via ajax post it to the server for persistence.   First order of business is to deal with the viewmodel (JSON) object. To most the JSON stringifier sounds familiar. The JSON stringifier converts JavaScript data structures into JSON text. JSON does not support cyclic data structures, so be careful to not give cyclical structures to the JSON stringifier. You may ask, is this the best way to do it? What about those observables and other Knockout properties that I don’t want to persist or want their actual value persisted and not their function, etc. Not sure if you were aware, but KO already has a method; ko.utils.stringifyJson() - it's mostly just a wrapper around JSON.stringify. (which is native in some browsers, and can be made available by referencing json2.js in others). What does it do that the regular stringify does not is that it automatically converts observable, dependentObservable, or observableArray to their underlying value to JSON. Hold on! There is a new feature in this version of Knockout, the ko.toJSON. It is part of the core library and it will clone the view model’s object graph, so you don’t mess it up after you have stringified  it and unwrap all its observables. It's smart enough to avoid reference cycles. Since you are using the MVVM pattern it would assume you are not trying to reference DOM nodes from your view. Wait a minute. I can already see this info on the http://knockoutjs.com/examples/contactsEditor.html website, why mention it all here? First of this is a much nicer blog, no orange ? At this time, you may want to have a look at the blog and see what I am talking about. See the save event, how they stringify the view model’s contacts only? That’s cool but what if your view model is a representation of your object you want to persist, meaning it has no property that represents the json object you want to persist, it is the view model itself. The example in http://knockoutjs.com/examples/contactsEditor.html assumes you have a list of contacts you may want to persist. In the example here, you want to persist the view model itself. The viewmodel here looks something like this:     var myViewmodel = {         accountName: ko.observable(""),         accountType: ko.observable("Active")     };     myViewmodel.isItActive = ko.dependentObservable(function () {         return myViewmodel.accountType() == "Active";     });     myViewmodel.clickToSaveMe = function() {         SaveTheAccount();     }; Here is the function in charge of saving the account: Function SaveTheAccount() {     $.ajax({         data: ko.toJSON(viewmodel),         url: $('#ajaxSaveAccountUrl').val(),         type: "POST",         dataType: "json",         async: false,         success: function (result) {             if (result && result.Success == true) {                 $('#accountMessage').html('<span class="fadeMyContainerSlowly">The account has been saved</span>').show();                 FadeContainerAwaySlowly();             }         },         error: function (xmlHttpRequest, textStatus, errorThrown) {             alert('An error occurred: ' + errorThrown);         }     }); //ajax }; Try run this and your browser will eventually freeze up or crash. Firebug will tell you that you have a repetitive call to the first function call in your model that keeps firing infinitely.  What is happening is that Knockout serializes the view model to a JSON string by traversing the object graph and firing off the functions, again-and-again. Not sure why it does that, but it does. So what is the work around: Nullify your function calls and then post it:         var lightweightModel = viewmodel.clickToSaveMe = null;         data: ko.toJSON(lightweightModel), So then I traced the JSON string on the server and found it having issues with primitive types. C#, by the way. So I changed ko.toJSON(model) to ko.toJS(model), and that solved my problem. Of course you could just create a property on the viewmodel for the account itself, so you only have to serialize the property and not the entire viewmodel. If that is an option then that would be the way to go. If your view model contains other properties in the view model that you also want to post then that would not be an option and then you’ll know what to watch out for. Hope this helps.
