Valgrind Home
february 2010 by jtth
Valgrind is an award-winning instrumentation framework for building dynamic analysis tools. There are Valgrind tools that can automatically detect many memory management and threading bugs, and profile your programs in detail. You can also use Valgrind to build new tools.
The Valgrind distribution currently includes six production-quality tools: a memory error detector, two thread error detectors, a cache and branch-prediction profiler, a call-graph generating cache profiler, and a heap profiler. It also includes two experimental tools: a heap/stack/global array overrun detector, and a SimPoint basic block vector generator. It runs on the following platforms: X86/Linux, AMD64/Linux, PPC32/Linux, PPC64/Linux, and X86/Darwin (Mac OS X).

Daring Fireball: Ronco Spray-On Usability
january 2010 by jtth
The distributed, collaborative nature of open source software works for developer-level software, but works against user-level software. Imagine a motion picture produced like a large open source project. Different scenes written and directed by different people, spread across the world. Editing decisions forged by group consensus on mailing lists. The result would be unfocused, incoherent, and unenjoyable.

PS3Cluster Guide: By The Cluster Workshop
december 2008 by jtth
Our community guide allows you to set up your own MPI (Message Passing Interface) based supercomputer cluster with the Playstation 3. This guide was co-written by Gaurav Khanna, based on his previous work on the Gravity Grid and is a current run-time environment for the research of co-author (Chris Poulin), based on his current work in distributed pattern recognition. As such, we currently utilize the Fedora Core for this infrastructure and illustrate a "how-to" below. NOTE: We focus on the Fedora 8 distribution, due to prevalence of Fedora and its Cell SDK (3.0) compatibility. Finally, this content should be considered open source, and here is the license.

PyInstaller
november 2008 by jtth
PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux and Irix. Its main advantages over similar tools are that PyInstaller works with any version of Python since 1.5, it builds smaller executables thanks to transparent compression, it is multi-platform (so you can build one-file binaries also under Linux), and use the OS support to load the dynamic libraries, thus ensuring full compatibility.
