PieSpy is an IRC bot that monitors a set of IRC channels. It uses a simple set of heuristic methods to infer relationships between pairs of users. These inferrences allow PieSpy to build a mathematical model of a social network for any channel. These social networks can be drawn and used to create animations of evolving social networks.
PieSpy has also been used to visualize Shakespearean social networks.This page got slashdotted on 11 March 2004, with the site getting 250,000 hits per hour. Thanks to Notnet for making sure it all stayed alive!
PieSpy was presented at the Information Visualization conference (IV04) in July 2004. Read the full paper online. It has also appeared in Computer Weekly, ct magazine, and I was interviewed live on BBC Radio Kent.
Enhancements:
- Now tracks nickname changes. Generates images five times faster. Removes formatting and colors from messages. The source code has been refactored to make it easy to add new InferenceHeuristics, which are used to work out who is talking to whom - if you create any good ones, let me know! The config file lets you apply different weightings to each InferenceHeuristic.

4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler.
4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports over 85% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, recursion, include files, etc.
It comes with an RPN calculator, line editor, compiler, decompiler, C-source generators, and a virtual machine.
Enhancements:
- More CORE words and most of the DOUBLE wordset are supported.
- Output buffers can be flushed.
- An experimental multitasking environment was added.

Rocks Cluster is a complete "cluster on a CD" solution for x86 and IA64 Red Hat Linux COTS clusters.
Building a Rocks cluster does not require any experience in clustering, yet a cluster architect will find a flexible and programmatic way to redesign the entire software stack just below the surface (appropriately hidden from the majority of users).
Although Rocks includes the tools expected from any clustering software stack (PBS, Maui, GM support, Ganglia, etc), it is unique in its simplicity of installation.
From a hardware component and raw processing power perspective, commodity clusters are phenomenal price/performance compute engines. However, if a scalable ``cluster management strategy is not adopted, the favorable economics of clusters are offset by the additional on-going personnel costs involved to ``care and feed for the machine. The complexity of cluster management (e.g., determining if all nodes have a consistent set of software) often overwhelms part-time cluster administrators, who are usually domain application scientists. When this occurs, machine state is forced to either of two extremes: the cluster is not stable due to configuration problems, or software becomes stale, security holes abound, and known software bugs remain unpatched.
While earlier clustering toolkits expend a great deal of effort (i.e., software) to compare configurations of nodes, Rocks makes complete Operating System (OS) installation on a node the basic management tool. With attention to complete automation of this process, it becomes faster to reinstall all nodes to a known configuration than it is to determine if nodes were out of synchronization in the first place. Unlike a users desktop, the OS on a cluster node is considered to be soft state that can be changed and/or updated rapidly.
This is clearly more heavywieght than the philosophy of configuration management tools [Cfengine] that perform exhaustive examination and parity checking of an installed OS. At first glance, it seems wrong to reinstall the OS when a configuration parameter needs to be changed. Indeed, for a single node this might seem too severe. However, this approach scales exceptionally well, making it a preferred mode for even a modest-sized cluster. Because the OS can be installed from scratch in a short period of time, different (and perhaps incompatible) application-specific configurations can easily be installed on nodes. In addition, this structure insures any upgrade will not interfere with actively running jobs.
One of the key ingredients of Rocks is a robust mechanism to produce customized distributions (with security patches pre-applied) that define the complete set of software for a particular node. A cluster may require several node types including compute nodes, frontend nodes file servers, and monitoring nodes. Each of these roles requires a specialized software set. Within a distribution, different node types are defined with a machine specific Red Hat Kickstart file, made from a Rocks Kickstart Graph.
A Kickstart file is a text-based description of all the software packages and software configuration to be deployed on a node. The Rocks Kickstart Graph is an XML-based tree structure used to define RedHat Kickstart files. By using a graph, Rocks can efficiently define node types without duplicating shared components. Similiar to mammalian species sharing 80% of their genes, Rocks node types share much of their software set. The Rocks Kickstart Graph easily defines the differences between node types without duplicating the description of their similarities. See the Bibliography section for papers that describe the design of this structure in more depth.
By leveraging this installation technology, we can abstract out many of the hardware differences and allow the Kickstart process to autodetect the correct hardware modules to load (e.g., disk subsystem type: SCSI, IDE, integrated RAID adapter; Ethernet interfaces; and high-speed network interfaces). Further, we benefit from the robust and rich support that commercial Linux distributions must have to be viable in todays rapidly advancing marketplace.
Wherever possible, Rocks uses automatic methods to determine configuration differences. Yet, because clusters are unified machines, there are a few services that require ``global knowledge of the machine -- e.g., a listing of all compute nodes for the hosts database and queuing system. Rocks uses an SQL database to store the definitions of these global configurations and then generates database reports to create service-specific configuration files (e.g., DHCP configuration file, /etc/hosts, and PBS nodes file).
Enhancements:
- Rocks v4.3 is released for i386 and x86_64 CPU architectures. New features: Rocks command line - initial release of the Rocks command line which facilitates non-SQL administrative access to the database; PXE First - hosts can now be configured in BIOS with a boot order of CD, PXE, hard disk. Enhancements: based on CentOS 4.5 and all updates as of July 4, 2007; Anaconda installer updated to 10.1.1.63; performance improvement when building torrent files for the Avalanche Installer; database indirects, more flexibility with Rocks variables; Globus updated to gt4.0.4 with web services....

JikesTM 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:

* 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.

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. Since the release of the source they have continued to work on the compiler as contributors; however recently have officially been moved on to 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.

PHP Exif Library in short PEL is a library that lets you manipulate Exif (Exchangeable Image File Format) data. This is the data that digital cameras place in their images, such as the date and time, shutter speed, ISO value and so on.
Using PEL, one can fully modify the Exif data, meaning that it can be both read and written. PEL is written completely in PHP and depends on nothing except a standard installation of PHP, version 5, which was released on July 13th 2004.
Main features:
- Reads and parses both JPEG and TIFF images.
- Supports reading and writing all Exif tags.
- Supports internationalisation.
- Extensible object-oriented design. PEL utilizes the new features in PHP 5.
- Tested with SimpleTest (11 camera models tested, plus core tests).
- Fully documented with PhpDocumentor, see the online API documentation.
