Although the definition of system programming is fuzzy, it can be described as having to think at the bit, byte, instruction or CPU cycle level. Systems programming also implies demanding performance and reliability requirements. Joe Duffy, engineering director at Microsoft, presented strategies for system programming in C# at QCon New York. He also discusses pitfalls and how to mitigate them.
Mark Stoodley, Architect at IBM talks to Rags Srinivas about Eclipse OMR project, an open-source virtual machine toolkit to help create runtime environments for any language.
PyPy 4.0 is a new major version of Python Just-in-Time compiler, bringing many new features, such as SIMD vectorization support, warmup time improvements, and improvements to Numpy. PyPy claims to be more than six times faster than CPython.
The GNU Project has announced the release of GCC 5.1. The first major release of GCC 5 comes with many new features and improvements, including improved support for C++11/14, a new libstdc++ ABI, and a machine-code JIT embeddable library.
The .NET Foundation has announced the release of a new project called LLILC (pronounced "lilac"). The project, initiallycontributed by Microsoft, aims to provide a new LLVM-based native code compiler for .NET Core which will make it possible to run .NET programs "on any platform that CoreCLR can be ported to and that LLVM will target."
Mono 3.8.0 was released last week. It comes with several performance and scalability improvements across the runtime, as well as finishes the Windows port.
RyuJIT, Microsoft's project to produce an improved Just-in-Time compiler for .NET, has taken a big step forward on the compatibility front by adding support for Windows 7 and Windows Server 2008. Now developers on these platforms can test RyuJIT with their code.
Azul Systems announces the release of ReadyNow! in the latest version of Azul's Zing runtime for Java. Includes a series of algorithms designed to obviate the need for "warming-up" the Java Virtual Machine.
The next generation .NET compiler from Microsoft, codename RyuJIT, has just had a second preview version release. While still very much a beta, the initial results are impressive when compared to both the first preview and the current 64-bit JIT compiler used by NET today.
Recognizing the shift from 64-bit applications as server-specific to their broadened use on most platforms, Microsoft has announced the RyuJIT project, which is developing a vastly improved just-in-time compiler for .NET applications.
Facebook has announced using HHVM, a HipHop VM with JIT compilation, in production, a solution that has unified their development and deployment environments, providing significant performance gains for developers.
