X10 is an experimental new language currently under development at IBM in collaboration with academic partners. The X10 effort is part of the IBM PERCS project (Productive Easy-to-use Reliable Computer Systems) in the DARPA program on High Productivity Computer Systems. The PERCS project is focused on a hardware-software co-design methodology to integrate advances in chip technology, architecture, operating systems, compilers, programming language and programming tools to deliver new adaptable, scalable systems that will provide an order-of-magnitude improvement in development productivity for parallel applications by 2010.

X10 aims to contribute to this productivity improvement by developing a new programming model, combined with a new set of tools integrated into Eclipse and new implementation techniques for delivering optimized scalable parallelism in a managed runtime environment. X10 is a type-safe, modern, parallel, distributed object-oriented language intended to be very easily accessible to Java programmers.

It is targeted to future low-end and high-end systems with nodes that are built out of multi-core SMP chips with non-uniform memory hierarchies, and interconnected in scalable cluster configurations. A member of the Partitioned Global Address Space (PGAS) family of languages, X10 highlights the explicit reification of locality in the form of places; lightweight activities embodied in async, future, foreach, and ateach constructs; constructs for termination detection (finish) and phased computation (clocks); the use of lock-free synchronization (atomic blocks); and the manipulation of global arrays and data structures.

An Eclipse-based Integrated Development Environment (IDE) has been developed at IBM for X10 to help further increase programmer productivity by providing state-of-the-art functionality for viewing, editing, navigating, executing, and manipulating X10 programs. The X10 Development Toolkit (X10DT) is intended to be a full-featured IDE for X10 offering the features Java programmers have come to love and depend upon in Eclipse: a source editor with various coding assists, lightweight information pop-ups, high-level and low-level navigation views, powerful search capabilities, application launch configuration management, refactoring, and debugging support. In addition, the X10DT will include tools, views and refactorings that specifically address the development of highly concurrent software in X10.

mod_auth_ibmdb2 is an Apache authentication module using IBM DB2 as the backend database for storing user and group information. mod_auth_ibmdb2 supports several encryption methods.
mod_authnz_ibmdb2 is designed for Apache 2.2.x.
mod_auth_ibmdb2 is designed for Apache 2.0.x and 1.x.
I also provide UDFs for DB2 to generate passwords within DB2. They are compatible to the functions that are used in Apaches htpasswd utility.
Main features:
- runs under Apache 2.2.x (mod_authnz_ibmdb2)
- runs under Apache 1.x and Apache 2.0.x (mod_auth_ibmdb2)
- user authentication:
- md5
- normal md5 hash (32 chars as in php)
- seeded md5 value (as generated with Apaches htpasswd utility or as in /etc/shadow)
- crypt
- plain text
- no password (checks only if user exists)
- if passwords are encrypted, the validation process checks the kind of encryption method
- support for user and group conditions (restricting result set of query)
- caching support for users and groups
- UDFs for DB2 to generate passwords within DB2
- php scripts for importing users to DB2
- man pages

EasyBMP is a simple, cross-platform C++ library designed for easily reading, writing, and modifying Windows bitmap (BMP) image files. You can learn more about the history and goals of the project here.
The library is oriented towards the novice programmer with little formal experience, but it is sufficiently capable for anybody who desires to do I/O and pixel operations on 1-bit, 4-bit, 8-bit, 24-bit, or 32-bit BMP files.
EasyBMP is intended to be cross-platform on both little-endian (e.g., x86, x86-64) and big-endian (e.g., IBM PowerPC, Sun Sparc) architectures. So far, it has been tested on x86 with Linux (2.4.x, 2.6.x kernels and g++ and icc) and Windows (XP Pro, XP Home, and 2K Pro with MinGW/g++), as well as on a Sun Sparc 4 machine (Solaris 5.9 with g++). EasyBMP should be solid on little-endian architectures and experimental on big-endian architectures.
Enhancements:
- This bug focuses on minor bugfixes, particularly in the copy constructor.
- Numerous other small bugs have also been fixed.

Jikes RVM is a compiler that translates JavaTM source files as defined in The Java Language Specification into the bytecoded instruction set and binary format defined in The Java Virtual Machine Specification.

You may wonder why the world needs another Java compiler, considering that Sun provides javac free with its SDK. Jikes has five advantages that make it a valuable contribution to the Java community: [OSI Certified Logo]

* Open source. Jikes is OSI Certified Open Source Software. OSI Certified is a certification mark of the Open Source Initiative.
* Strictly Java compatible. Jikes strives to adhere to both The Java Language Specification and The Java Virtual Machine Specification as tightly as possible, and does not support subsets, supersets, or other variations of the language. The FAQ describes some of the side effects of this strict language conformance.
* High performance. Jikes is a high performance compiler, making it ideal for use with larger projects.
* Dependency analysis. Jikes performs a dependency analysis on your code that provides two very useful features: Incremental builds and makefile generation.
* Constructive Assistance. Jikes strives to help the programmer write better code in two key ways. Jikes has always strived to provide clear error and warning text to assist the programmer in understanding problems, and now with release 1.19 Jikes helps point out common programming mistakes as documented in Effective Java.

Abridged from a FAQ entry which was adapted from some material by Lou Grinzo for an article he wrote.

The fact that Jikes is a high-performance, highly compatible Java compiler that can be used on almost any computing platform makes it an interesting program and worth investigating for almost any Java programmer. But Jikes is also notable because it lies at the center of two events: the adoption of open source philosophy and practice by large corporations, and the continued growth of Java for Linux.

Its worth pointing out that Jikes is not, and is not intended to be, a complete development environment -- it is simply a command line compiler. It should not be considered a replacement for more complete tools, such as Source Navigator or IBMs VisualAge for Java which provide sophisticated graphical IDEs (Integrated Development Environments).

The Jikes compiler was released in binary form in April 1997 on the IBM alphaWorks site. Jikes for Linux was released on 15 July 1998. The response was overwhelming -- Jikes had more downloads in the three months after the announcement than in the fifteen months before the announcement.

Around the end of March 2002, IBM opened a fledgling community hosting location attached to their developerWorks site with Jikes as a founding member. Approximately 3 years later this server was decommissioned and the most active projects migrated into SourceForge.net hosting options. During those three years Jikes was the #1 most popular project every month, often by a large margin. We approached nearly 250,000 downloads while residing at dw/oss, and had been consistently tallying triple digit daily downloads.

Release of Jikes for Linux was soon followed by requests to open up the source. Many notes and comments from users suggested this would be a good idea. The source was released under a liberal license in December 1998 to make a very visible demonstration of IBMs commitment to open standards and to Java Technology, to make Jikes more reliable and accessible, to encourage more widespread use of Java Technology, to encourage standardization of Java Technology, and to gain some experience actually running an open source project. This marked the start of one of IBMs first efforts in the open source arena.

The original alphaWorks version of Jikes was written by Philippe Charles and Dave Shields of the IBM T. J. Watson Research Center. For awhile after the release of the source they continued to work on the compiler as contributors; however, shortly after the project migrated to developerWorks Open Source Server they were officially moved off onto other projects within IBM. Today there are no IBMers who work on Jikes as part of their job description. Jikes survives today soley based on the free time contributions of members of the open source community.

The source code is available under IBMs Public License, which has been approved by the OSI (Open Source Initiative) as a fully certified open source license. The project provides access to the complete CVS development tree, which includes not only Jikes, but also the source for the Jacks Test Suite and the Jikes Parser Generator used to build Jikes. Jikes is included in many Open Source Operating Systems. The Jacks Test Suite is a replacement for the Jikestst package.
