Multithreading and WPF 4.5
WPF 4.5 has improved its support for multi-threaded data binding, but the technique is still risky. This report attempts to explain how it works and what’s involved in using it safely.

MSEPT'12 - Conference on Software Engineering for Multicore Systems
It is hard to leverage the parallelism provided by recent processor architectures. As these CPUs are now available even in the low cost price sector, the main challenge of software engineers is to utilize the processors in their applications or apps. The International Conference on Multicore Software Engineering, Performance, and Tools (MSEPT'12) will focus on possible answers.

Task Parallel Library Improvements in .NET 4.5
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.

Task Parallel Library for Silverlight
Silverlight’s asynchronous service model forces developers to deal with multi-threading from the very beginning. So it seems odd that Microsoft choose to omit the Task Parallel Library, which is the core of .NET’s multi-threading infrastructure. Fortunately there are options.

Software Architecture in the Movies
Keeping up-to-date with software architecture can be a tough endeavor. Information is normally available within thick books or somewhere hidden in the Web. Another more entertaining way can be to watch clips available at video sites such as YouTube and Vimeo.

Rx 1.0 Solves the Problem of Asynchronous Data Access
Microsoft has released version 1.0 of their Reactive Extensions (Rx) library after two years in incubation. Rx combines event-driven UI with LINQ, concurrency and asynchronous calls.

C++ AMP Provides Massive Parallelism
Microsoft wants to give C++ developers tools for writing parallel applications running on zillions of GPUs/cores locally or in the cloud.

Explaining .NET’s Barrier Class
With the increased emphasis on multi-core systems an understanding of parallel and concurrent programming is more important than ever. Fortunately .NET 4 has made a lot of advances in the types of synchronization primitives available to developers. One such primitive is the Barrier, which Emad Omara uses to implement a parallel merge sort.

Erlang Copied Scala's Actors & Erlang's VM is almost a Clone of the JVM
Erlang Co-creators, Joe Armstrong and Robert Virding, admit that Erlang is heavily inspired by the Java world. In an interview at ErlangFactory 2011 SF, they reveal how Scala Actors had shaped their work in what they then called Erlang Processes. Moreover, they acknowledge the fact that Erlang's VM is barely a clone of the famous JVM.

TPL Dataflow – The Successor to CCR
TPL Dataflow is Microsoft’s new library for highly concurrent applications. Using asynchronous message passing and pipelining, it promises to offer more control than thread pools and better performance than manual threading. The downside is that you have to adhere to design patterns that may be unfamiliar to .NET programmers.

Why Microsoft Believes that VB and C# Need an Asynchronous Syntax
The new Async CPT for VB and C# looks like it may actually make it into the core language. But with all the emphasis on multi-core systems, why is Microsoft investing so heavily in syntax for designed specifically for making single-threaded asynchronous programming easier?
