Dataflow Blocks are the backbone of the .NET 4.5’s new high performance parallel processing library. And while they offer a lot of functionality out of the box, there will be times when a custom block is necessary. Zlatko Michailov has put together a document outlining the process and many of the traps you may encounter.
Beside C/C++, Google Native Client has added support for runtimes such as Mono, and a richer set of Pepper interfaces: accelerated 3D, full-screen, File IO, debugging, and others. New languages -Lua, TCL, OCaml- are being ported, and several major producers have ported their game engines or their games to NaCl.
Microsoft has been working on ways to improve the performance of parallel applications in .NET 4.5, specifically those using the Task Parallel Library. One of most impressive improvements is reducing the overhead for waiting on 100,000 tasks from 12,000,000 bytes to a mere 64 bytes.
IBM has recently prototyped a software architecture that can deal with large amount of data flows. IBM’s software is built for the SKA telescope (Square Kilometre Array) and allows to automatically classify astronomical objects. Radio astronomer Melanie Johnston-Hollitt at Victoria University, Wellington , NZ, has collaborated with IBM for developing the system.
ARM is offering a community edition of their Development Studio 5, containing a debugger and a performance analyzer of Android native code.
When it comes to performance developers often need to turn to partial page caching. This report looks at the current state of caching in ASP.NET and introduces a new project for MVC 3 called MvcDonutCaching.

The latest Ruby release 1.9.3 further improves the stability and performance of the 1.9 series and brings only few new features. Ruby's license changed to 2-clause BSD + Ruby License instead of GPLv2 + Ruby License.
StackExchange is built on the ASP.NET and SQL Server stack. Recently, Sam Saffron and Marc Gravell blogged about their experience identifying and solving a performance problem that was finally traced to the .NET GC GEN-2 objects. There is a lot to be taken away from their experience for everyone tuning performance for applications in production.
Application Performance Measurement (APM) vendor AppDynamics has released AppDynamics Lite version 2.0, bringing new features from their commercial product into the free version.
Solutions Design has released ORM Profiler, a tool meant to help improve data access layer performance. It tracks and logs ADO.NET calls so that developers can analyze their data access and discover potential problems.
