Old but not rusty

I started to utilize my GTX970 as parallel processing device. A strategy to support such old device is to downgrade operation system to a version that CUDA 5.5 toolkit supports. I still have no good progress with Ubuntu 12.0.4 but already built toolkit as well on Windows 10 especially via Visual Studio 2012 that available in visual studio web site. Thank you again for support historical versions of Visual Studio and business products, it often required for old devices maintenance.

Decorator is going to a platform

PostSharp with free 10 classes licenses is going to be in Ubuntu LTS soon.
A trivial announce with not trivial changes in IL code synthesis i think.  When you started to work with porting libraries and ASP.NET to a target then this instrument will help to understand a difference that hidden in linux.
