In-Process Side-by-Side, or In-Proc SxS is a process whereby assemblies written in .NET4 and .NET2 co-exist together in runtime. This is possible because a process is able to host multiple version of .NET CLR in a single process. This means if an application is recompiled to run against the .NET Framework 4 runtime and still has dependent assemblies built against .NET 2.0, those assemblies will load on the .NET 4 runtime transparent to the user. It faces problem (if .NET4 runtime is used) in the following areas: a) Shell Extension support is limited. Application built with earlier version wil fail. b) C++/CLI section which specifically states that a pre-2.0 mixed mode assembly can only load in a v2 CLR. The v4 CLR does not support this scenario. There is no solution to this problem. You have to recompile the mixed mode assembly under v4 or switch back to v2 for your application. http://msdn.microsoft.com/en-us/magazine/ee819091.aspx

The documentation provided by mongodb to build on Fedora is pretty accurate. Here is the link to the document . Just have to make sure that you have got all the required tools like boost and scons that is vital for the build. Build can be trigger using the following command: scons all

It is really easy, just following the instruction from here and set the prefix to your preferred build directory; For example, set the mono binaries to /tmp/mono_build. ./configure --prefix=/tmp/mono_build; make; make install That's it.

Sometimes you might want your Enterprise Library logging configuration file to kept separately and maybe you're not going to put an entry even in your web.config using [Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ConfigurationSourceSection]. The following codes shows how this can be accomplished:- // Assuming the configuration file is default [loggingConfiguration] and in your current .exe directroy FileConfigurationSource fileSrc = new FileConfigurationSource("Test.config"); // If you would like to validate your configuration // var loggingSection = fileSrc.GetSection("loggingConfiguration"); LogWriterFactory wfac = new LogWriterFactory(new FileConfigurationSource("Test.config")); var Writer = wfac.Create(); LogEntry logEntry = new LogEntry(); logEntry.Message = "Life"; Writer.Write(logEntry); Your new configuration file is ca

Some performance notes that i got from MSDN. JIT compiler performs the following optimization given the small amount of time: •Constant folding •Constant and copy propagation •Common subexpression elimination •Code motion of loop invariants •Dead store and dead code elimination •Register allocation •Method inlining •Loop unrolling (small loops with small bodies) Value types, including integral types, floating point types, enums, and structs, typically live on the STACK. Reference types and boxed value types live in the HEAP. They are addressed by object references, which are simply machine pointers just like object pointers in C/C++. NGEN, a tool which "ahead-of-time" compiles the CIL into native code assemblies 9 million allocation Type Size of Allocation Execution Time string 575,783 00:00:2739811 int 8620 bytes - 40 instances 00:00:2515444 short 10472 bytes - 238 instances 00:00:2538425 employee 1,440,457,523

When you try to install using Microsoft MSI, you bump into the following message “Error Opening Installation log file. Verify that the specified log file location exists and is writable” Workaround, extract the .exe file by using the following command below NM33_x86.exe /c /t:c:\tools\networkmonitor the /t switch is used to tell installer where to extract the file. Then try to run netmon.msi to install network monitor. I tried it with Network Monitor 3.3 and it works (Netmon.msi and Microsoft_Parsers.msi)

This is going to be an ongoing update to some interesting streaming algorithm that i found over the web. If anyone have any input, please let me know. -- Haven't really work on it yet --

This is going to be an ongoing update to some interesting recommendation algorithm that i found over the web. If anyone have any input, please let me know.

When you're using jquery's class selectors for example, $('a.lookupScript'), it will work in Mozilla but not on IE. So you gotta make sure that you got the case right. :)

Firebug detected an illegal character while loading javascript, to fix this just have to open up the javascript with a proper texteditor and remove those illegal character. Pretty simple i guess. You can find more info from here
