Hadoop World 2009 @ The Dumping Ground
Eric Baldeschwieler from Yahoo gave an impressive talk about what they’re doing with Hadoop. Yahoo is running clusters at a simply amazing scale. They have several different clusters, totally some 86 PB of disk space, but their largest is a 4000-node cluster with 16 PB of disk, 64 TB of RAM, and 32,000 CPU cores. One of the most compelling points they made was that Yahoo’s experiences prove that Hadoop really does scale as designed. If you start with a small grid now, you can be sure that it will scale up – way up.
Eucalyptus Systems (Open-source cloud computing)
Eucalyptus is an open-source system for implementing on-premise private and hybrid clouds using the hardware and software infrastructure that is in place, without modification.
Dependency Walker (depends.exe) Home Page
Dependency Walker is a free utility that scans any 32-bit or 64-bit Windows module (exe, dll, ocx, sys, etc.) and builds a hierarchical tree diagram of all dependent modules. For each module found, it lists all the functions that are exported by that module, and which of those functions are actually being called by other modules. Another view displays the minimum set of required files, along with detailed information about each file including a full path to the file, base address, version numbers, machine type, debug information, and more.
The Computer Language Benchmarks Game
Benchmarking programming languages?
How can we benchmark a programming language?
We can't - we benchmark programming language implementations.
How can we benchmark language implementations?
We can't - we measure particular programs.
Spark's Pensieve - Recommend C++?
So if your abstractions are leaky, in that they are going to
have strange interactions with each other under-the-hood, then you
should quickly start developing an understanding of what happens under
the abstractions you are given. Your effectiveness as a
Nested VM
NestedVM provides binary translation for Java Bytecode. This
is done by having GCC compile to a MIPS binary which is then translated
to a Java class file. Hence any application written in C, C++, Fortran,
or any other language supported by GCC can be run
YouTube - Getting C++ Threads Right
The advent of multicore processors has generated profound
debate on the merits of writing parallel programs with threads and
locks. Nonetheless, for many application domains, this remains the
standard paradigm for writing parallel programs, and at the mom
SAI || software architecture for immersipresence
SAI is a new software architecture model for designing,
analyzing and implementing applications performing distributed,
asynchronous concurrent processing of generic data streams. SAI
provides a universal framework for the distributed implementation of al

Building your own operating system - The Code Project - System
If you know how an operating system works, it will help you a
lot in programming, especially for system programs like device drivers;
even for non-system-programming, it can help a lot. And also, I'm sure
every one would like to have their own operating s
SableVM Project
SableVM is a robust, extremely portable, efficient, and
specifications-compliant Java virtual machine that aims to be easy to
maintain and to extend. It features a state-of-the-art and efficient
interpreter engine. Its source code is very accessible and e
Noodle Open Source | NoodleGlue
NoodleGlue is a system which generates the source code
