• ASP.NET MVC 2 and Windows Azure

  If you upgrade an Azure web instance to use ASP.NET MVC 2, make sure you mark the System.Web.Mvc reference as Copy Local = true.  Otherwise, your deployment will fail.  And you wont get any good feedback from Windows Azure as to the cause of the problem.  So youll start searching the web for help, and perhaps youll stumble on this post, and youll realize that you didnt set Copy Local = true on your System.Web.Mvc assembly reference in your ASP.NET MVC 2 web instance.  And youll  leave happy (or at least slightly happier) than when you came. That is all. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

• WebPermission Problem with godaddy hosting

  - by Werewolf

  I purchased a windows web host from Godaddy.com When I want to use an Email verification component (that wants to connect to the Internet) on my host, I get an error related to Web Permission denied. (ASP.NET 4) As I search, I found that Godaddy has changed web permission in ASP.NET and restrict some features of that. When I want to take web permission on my site, I get error 500 (Internal Server Error) Can I give permission to an assembly only or solve my problem in another way? I ask this question from Godaddy support team, but I didn't get any answers. Please help me :( Thanks all...

• Fast software color interpolating triangle rasterization technique

  - by Belgin

  I'm implementing a software renderer with this rasterization method, however, I was wondering if there is a possibility to improve it, or if there exists an alternative technique that is much faster. I'm specifically interested in rendering small triangles, like the ones from this 100k poly dragon: As you can see, the method I'm using is not perfect either, as it leaves small gaps from time to time (at least I think that's what's happening). I don't mind using assembly optimizations. Pseudocode or actual code (C/C++ or similar) is appreciated. Thanks in advance.

• InvalidProgramException Running Unit Test

  - by Anthony Trudeau

  There is a bug in the unit testing framework in Visual Studio 2010 with unit testing.  The bug appears in a very special circumstance involving an internal generic type. The bug causes the following exception to be thrown: System.InvalidProgramException: JIT Compiler encountered an internal limitation. This occurs under the following circumstances: Type being tested is internal or private Method being tested is generic  Method being tested has an out parameter Type accessor functionality used to access the internal type The exception is not thrown if the InternalsVisibleToAttribute is assigned to the source assembly and the accessor type is not used; nor is it thrown if the method is not a generic method. Bug #635093 has been added through Microsoft Connect

• New Development Snapshot

  I finally did the work necessary to improve the codegen for finally handlers. More improvements are still possible, but at least most finally handlers will now execute without touching the exception object (and hence without having to do any mapping/stack trace collection work). It also means that assembly file sizes are a little bit smaller and that the debugging experience should be improved (less exception catching & rethrowing). Changes: ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

• From Imperative to Functional Programming

  - by user66569

  As an Electronic Engineer, my programming experience started with Assembly and continue with PL/M, C, C++, Delphi, Java, C# among others (imperative programming is in my blood). I'm interested in add to my previous knowledge, skills about functional programming, but all I've seen until now seems very obfuscated and esoteric. Can you please answer me these questions? 1) What is the mainstream functional programming language today (I don't want to get lost myself studying a plethora of FP languages, just because language X has the feature Y)? 2) What was the first FP language (the Fortran of functional programming if you want)? 3) Finally, when talking about pure vs. non pure FP what are the mainstream languages of each category? Thank you in advance

• How do these hotshot developers keep changing their technology base ?

  - by pankajdoharey

  Yesterday I was watching a lynda.com iphone development video and this developer started telling about how he has worked on 17 different languages from the days of mainframes in assembly/Cobol to now on iPhone Objective-C. My question is how do these developers keep shifting to new technology, without fearing the loss of experience they already have about a particular technology. I am trying to shift to Java from PHP and market considers this as non-relevant experience. How do these guys do it without losing the pay and not being considered a fresher in a particular technology.

• What are deferred callbacks?

  - by tentimes

  I understand the idea of a callback, where I pass a function into another function and that function then uses the supplied function at will. I am struggling to understand deferred callbacks, even after googling it. Could someone provide a simple explanation please? I program in Ruby, but also know C/C++ a bit, but most of all I was a experienced assembly language programmer. So I am wondering is it a bit like a stack of callback addresses that get pop'd? I am hoping to learn jquery or node.js and these deferred callbacks seem integral to both. I understand basic threading principles (though mutex object makes my head hurt ;)

• How many CISC instructions do compilers use?

  - by Euphoric

  CISC processors have sometimes huge instruction sets. This makes assembly programming somehow easier. But it reduces overall effectivness of the whole chip. But how many of those instructions are used by modern compilers? I'm especialy interested in relation of CISC vs. RISC where in CISC, compiler can use specialised instructions, that might increase effectivness. But do compilers use those instructions? If yes, then how many of them are used?

• Running the application with F5 gives a message saying "\bin\Debug\Infrastructure.Layout.dll was not found"

  The problem here is the ProfileCatalog.xml file refers to the old assesmbly namesdlls. It does not get updated when the assembly names change. Steps to fix this issue: 1. Open the ProfileCatalog.xml file in the Shell project, and you'll find there are three ModuleInfo configuration items that need to have the solution name prefixed. 2. Prefix the dlls with the solution name. Recompile and everything will work fine. span.fullpost {display:none;}

• Visual Web Part as a Sandboxed solution

  - by Steve Clements

  You want the RAD wonderfulness of a visual web part, but it needs to be deployed as a Sandboxed solution. Problem? No, SharePoint powertools for visual studio to the rescue!   http://goo.gl/pQ9ct   There are a couple limitations, read the above page, nothing major. e.g. 1. Javascript debugging is not supported 2. Debugging asp.net code is not supported. 3. Use of <% Assembly Src= is not supported   I understand it does it by adding the markup as an embedded resource, but I haven't actually tried it yet!  To come!

You can add this cached folder as source.     For use nuget package without Visual studio you can try this trick.   open this in your explorer C:\Users\{yourusername}\AppData\Local\NuGet\Cache Now rename the file as described here. for example bootstrap.3.0.2.nupkg to bootstrap.3.0.2.rar open the rar and see the content folder. this folder contain the assembly/library that nuget install in your project.

• Silverlight 3.0 and ADO.NET data service framework(An error occurred while processing this request)

  - by ybbest

  Today , I try to write a Silverlight app that talks to SharePoint 2010 using the REST API.However after deploy the silverlight app and run the code , I got the following error.In order to fix this I need to make the target framework of your caller application to 4.0,in this case I need to use Silverlight 4.0 instead 3.0.After I have done that and redeploy the solution to the SharePoint.It works like a charm.   Exceptions details: System.Data.Services.Client.DataServiceQueryException: An error occurred while processing this request. Request version ’1.0′ is too low for the response. The lowest supported version is ’2.0′. However , if you got the error like this: Could not load type ‘System.Data.Services.Providers.IDataServiceUpdateProvider’ from assembly ‘System.Data.Services, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′,then you need to install ADO.NET Data Services Update for .NET Framework 3.5 SP1 ,you can download here (for windowns 7 and server 2008 r2 ) or here (for windows vista of server 2008).

• IE9 Preview disables CLR DEVPATH feature

  (This is not related to IKVM.NET, but since I spent several hours tracking this down, I thought I'd write it up here in the hope anyone else struggling with this will find it.) One of the lesser known (development) features of the CLR is the ability to override the regular Fusion assembly loading rules by setting the DEVPATH environment variable (and adding an entry to the machine.config to enable this).

• What do Embedded Software Developers do on a day to day basis?

  - by afree100

  Edit: I am not asking how to program embedded systems. I am asking how it is done in a practical business setting. I have searched for hours for information on what software developers actually do. More specifically, what coding challenges would one experience daily (e.g. code examples (although obviously not too large), specifics)? I am interested in Linux based embedded systems mainly, but any software development would be helpful (in the C/C++/Assembly areas). Also, regarding this, a distinction between junior, intermediate and senior developers would be helpful. Also, what is the best place to prepare for such things before getting a job for the first time?

• game programming career, vc++ reference and future of it [closed]

  - by Pappu Bacha

  1) I have quite a lot of interest in game programming and I (to my thought) am quite good at programming skills, I have developed some console based animations and text based animation games (like copter-it, snake, and a music visualization), should I invest in game programming? I have 2 years at college left. 2) If I am to pursue a career in game programming, and I select to go only with c++ and DirectX, is it enough? is assembly language necessary? 3) is Visual C++ or MFC dead? should I invest in it or not? 4) I am unable to find any reference book for Visual C++ 2008 or later (just like C++ the complete reference book) I need a book that covers the basic fundamentals and covers the most of the libraries etc.

• Running the Ubuntu Kernel and OS on custom processor

  - by xupv5

  This is hardly a theoretical question as many have done this, albeit there's very little information on the underlying processes. I'm developing a custom MIPS-based processor on which I would like to run ubuntu. I'm quite baffled as to what to do next after you've designed the instruction set and the computer architecture itself. I need to be able to run a kernel and OS but how does it all tie in? At the moment I'm researching into designing a compiler for the linux kernel to generate the appropriate assembly language. Is that a good way to go? What do I need to do after that?

• OAM OVD integration - Error Encounterd while performance test "LDAP response read timed out, timeout used:2000ms"

  - by siddhartha_sinha

  While working on OAM OVD integration for one of my client, I have been involved in the performance test of the products wherein I encountered OAM authentication failures while talking to OVD during heavy load. OAM logs revealed the following: oracle.security.am.common.policy.common.response.ResponseException: oracle.security.am.engines.common.identity.provider.exceptions.IdentityProviderException: OAMSSA-20012: Exception in getting user attributes for user : dummy_user1, idstore MyIdentityStore with exception javax.naming.NamingException: LDAP response read timed out, timeout used:2000ms.; remaining name 'ou=people,dc=oracle,dc=com' at oracle.security.am.common.policy.common.response.IdentityValueProvider.getUserAttribute(IdentityValueProvider.java:271) ... During the authentication and authorization process, OAM complains that the LDAP repository is taking too long to return user attributes.The default value is 2 seconds as can be seen from the exception, "2000ms". While troubleshooting the issue, it was found that we can increase the ldap read timeout in oam-config.xml.  For reference, the attribute to add in the oam-config.xml file is: <Setting Name="LdapReadTimeout" Type="xsd:string">2000</Setting> However it is not recommended to increase the time out unless it is absolutely necessary and ensure that back-end directory servers are working fine. Rather I took the path of tuning OVD in the following manner: 1) Navigate to ORACLE_INSTANCE/config/OPMN/opmn folder and edit opmn.xml. Search for <data id="java-options" ………> and edit the contents of the file with the highlighted items: <category id="start-options"><data id="java-bin" value="$ORACLE_HOME/jdk/bin/java"/><data id="java-options" value="-server -Xms1024m -Xmx1024m -Dvde.soTimeoutBackend=0 -Didm.oracle.home=$ORACLE_HOME -Dcommon.components.home=$ORACLE_HOME/../oracle_common -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:/opt/bea/Middleware/asinst_1/diagnostics/logs/OVD/ovd1/ovdGClog.log -XX:+UseConcMarkSweepGC -Doracle.security.jps.config=$ORACLE_INSTANCE/config/JPS/jps-config-jse.xml"/><data id="java-classpath" value="$ORACLE_HOME/ovd/jlib/vde.jar$:$ORACLE_HOME/jdbc/lib/ojdbc6.jar"/></category></module-data><stop timeout="120"/><ping interval="60"/></process-type> When the system is busy, a ping from the Oracle Process Manager and Notification Server (OPMN) to Oracle Virtual Directory may fail. As a result, OPMN will restart Oracle Virtual Directory after 20 seconds (the default ping interval). To avoid this, consider increasing the ping interval to 60 seconds or more. 2) Navigate to ORACLE_INSTANCE/config/OVD/ovd1 folder.Open listeners.os_xml file and perform the following changes: · Search for <ldap id=”Ldap Endpoint”…….> and point the cursor to that line. · Change threads count to 200. · Change anonymous bind to Deny. · Change workQueueCapacity to 8096. Add a new parameter <useNIO> and set its value to false viz: <useNIO>false</useNio> Snippet: <ldap version="8" id="LDAP Endpoint"> ....... .......  <socketOptions><backlog>128</backlog>         <reuseAddress>false</reuseAddress>         <keepAlive>false</keepAlive>         <tcpNoDelay>true</tcpNoDelay>         <readTimeout>0</readTimeout>      </socketOptions> <useNIO>false</useNIO></ldap> Restart OVD server. For more information on OVD tuneup refer to http://docs.oracle.com/cd/E25054_01/core.1111/e10108/ovd.htm. Please Note: There were few patches released from OAM side for performance tune-up as well. Will provide the updates shortly !!!

• If You Could Cut Your Meeting Times in ½ Would You?

  - by [email protected]

  By Brian Dayton on April 22, 2010 2:02 PM I know it sounds like a big promise. And what I'm thinking about may not cut a :60 minute meeting into :30 minutes, but it could make meetings and interactions up to 2X more productive. How? Social Media for the Enterprise, Not Social Media In the Enterprise Bear with me. I'm not talking about whether or not workers should or shouldn't have access to Facebook on corporate networks. That topic has been discussed @ length. I'm also not talking about the direct benefits of Social Networking tools like Presence (the ability to see someone online and ask a question in real-time), blogs, RSS feeds or external tools like Twitter. The Un-Measurable Benefits Would you do something that you believe will have a positive effect--but can't be measured? It's impossible to quantify the effectiveness of a meeting. However, what I am talking about would be more of a byproduct of all of the social networking tools above. Here's the hypothesis: As I've gotten more and more busy with work, family, travel and kids--and the same has happened to my friends and family--I'm less and less connected. But by introducing Facebook to my life I've not only made connections with longtime friends whom I haven't spoken to in years--but I've increased the pace and quality of interactions, on and offline, with close friends who I see and speak to every week. In some cases it even enhances the connections and interactions with those I see or speak to every day. The same holds true in an organization. Especially a larger one with highly matrixed organizational structures. You work with people on a project, new people come in with each different project and a disproportionate amount of time is spent getting oriented and staying current. Going back to the initial value proposition--making meetings shorter/more effective--a large amount of time is spent: - At Project Kick-off: Meeting and understanding team member's histories, goals & roles - Ongoing: Summarizing events since the last meeting or update email In my personal, Facebook life today I know that: - My best friend from college - has been stranded in India for 5 days because of the volcano in Iceland and is now only 250 miles from home - One of my co-workers started conference calls at 6:30 this morning - My wife wasn't terribly pleased with my painting skills in our new bathroom (disclosure: she told me this face to face too) Strengthening Weak Links A recent article in CIO Magazine, Three Dangerous Social Media Misconceptions (Kristen Burnham, March 12, 2010) calls out the #1 misconception as follows: 1. "Face-to-face relationships are far more valuable than virtual ones." While some level of physical interaction will always add value to relationships, Gartner says that come 2020, most relationships and teams will be based on "weak links"--that is, you may not have personally met a contact, but you'll know of or may have interacted with him via social sites like Facebook, LinkedIn and Twitter. The sooner your enterprise adopts these tools, the sooner your employees will learn them, and the sooner you'll begin to cultivate these relationships-of-the-future. I personally believe that it's not an either/or choice between face-to-face and virtual interactions. In fact, I'll be as bold as saying it doesn't matter. I can point to two extremely valuable work relationships that I've had over the past 5 years: - I shared an office with one of them - I met the other person, face-to-face, only once Both relationships were very productive. The dynamics were similar. The communication tactics differed immensely. What does matter is the quality, frequency and relevance of interactions. Still sound like too much? An over-promise? Stay tuned for my next post The Gap Between Facebook and LinkedIn. I'll also connect some of the dots with where Oracle Applications and technologies are headed.
