Soon - Near-Future Command Scheduler

Scheduling a task via At command can some times be tricky. Windows 2000 Resource kit' Soon.exe comes to rescue( though it uses At.exe anyways)

you may download soon from here

But beware of this bug which warns you that the task may be scheduled for the next day instead of the current day if you specify delay of less than 60 seconds

PS: If you are using Windows Xp/2003 try Schtasks which is far better than AT or Soon

Using Eclipse for developing .NET apps

Who said eclipse is only for java development

Follow these simple steps to create/run your mono apps on eclipse:

1. get Eclipse
2. get JRE
3. ensure you have the JRE path in your PATH environment variable
4. get Improve's C# plug-in
5. open eclipse pull File->New->Project and choose 'Simple' on the dialog presented
6. File->New->C# File

Your new file will be filled in with a simple template of a C# program

Socket Workbench V3.1

Socket Workbench is a tool for analyzing socket communications. It can be configured to run as a socket client or server, or you can run it in pass-through mode to intercept socket communications without packet sniffing. You can send and receive both text and binary data that you have typed in or read from a file. It can be used to "stress test" servers and clients. It's ideal tool for analyzing HTTP and SMTP as it includes a library of common protocols.

Monoppix 1.0 download rush

due to heavy downloads of Monoppix 1.0 ....its direct link is taken down. But there is torrent links anywayz. All you need to do to get the iso file is to install any torrent software...blogtorrent or bitorrent

After downloading the iso..just burn the iso to a cd or mount it to some emulator and you are ready for mono/.NET experience on it's own linux version.

Reduce False Sharing in .NET

software that performs well in a single threaded environment do not always perform as expected in multiprocessor/multithreaded environments. There are many well known non-platform specific issues with multithreaded applications running on MP systems. One of the most well known issues is that the processor cache line reloads due to what is known as false sharing. These misses effectively undo the scaling benefits of adding additional processors to systems. It forces the memory subsystem to reacquire data into the processor cache for every memory load/store a worker thread performs on certain types of global data.

Unfortunately, the .NET framework hides most of the logic that would allow you to overcome false sharing in a native environment. Memory management, both allocation and garbage collection is handled inside the .NET framework with very little exposure for you. The .NET framework does this to keep up the promise of writing once run on many platforms. But, the tradeoff is a significant scaling and performance impact on your multithreaded code.


   Take either of the following two possible approaches: 

  • Pad each thread's data element to ensure that elements owned by different threads all lie on separate cache lines. 
  • Use a local copy from stack for all updates, and then perform a global update that reflects these updates to the global entity.

False sharing problems can also be identified during the tuning stage using the VTune™ Performance Analyzer, and the appropriate measures can be taken in that stage to address this problem. In all cases, developers should avoid false sharing by carefully dividing the work among the threads to cache line boundaries.
