Multitalk project is a presentation program designed for giving more interactive and engaging talks. Slides are laid out in a two- dimensional canvas that you navigate in any direction, in real time, using the mouse.
All of your talks can be merged into the same space. You can zoom out and create hyperlinks between slides. Each slide may also contain nested expandable sections like a folding text editor. Every slide can have an arbitrary style to control layout and visual appearance.
Why another presentation program?
Other presentation programs force you to arrange your talk in a fixed order, and then to step through it in sequence - often while reading out the slides to the audience in a tedious manner! This means that in those programs:
- Theres no way to change the direction of your talk at presentation-time based on audience feedback.
- You cant have "optional" parts which you expand upon for longer, more detailed talks and present at an overview level otherwise, except by skipping slides.
- Theres no easy way to show central concepts or illustrate ones progress through the structure of the talk, except by regularly reinserting copies of the contents page.
- The speaker isnt actively involved in steering through and explaining the material, which can lead to poor communication.
- Updating multiple talks with shared material is difficult.
- You cannot view all of your talks in the same space.
- Presentation concerns are emphasised over content because slides are initially designed in a GUI rather than as plain text.
- Often the same template is used for all slides in a talk; putting the same abstract-but-vaguely-hitech-looking coloured pattern in the corner of each slide doesnt really add much to the talk.
What does Multitalk do better?
- Slides are laid out for display in a two-dimensional space which you can choose to navigate in real time in any direction.
- Slide text is written in a markup language using a normal text editor.
- Image placement is still controlled in a WYSIWYG manner using the program itself (which is quicker than pure markup language spacing commands).
- Slides can be any size and automatically resize to fit their contents; you can view multiple small ones at once or part of very large ones, so logical units dont have to be stretched to screen size.
- You can zoom out to rearrange slides or get an overview of the talk.
- Each slide acts like a folding text editor, with definable blocks which can be collapsed and expanded during the talk.
- You can define hyperlinks between different slides, which are spatially animated.
- You can define your own style templates to override all visual aspects, and each slide can independently use any style to highlight topics as required (you can have multiple "master slides" in other terminology).
Enhancements:
- This version adds LaTeX integration, which allows LaTeX syntax to be embedded within any slides text.

Rippy the Aggregator project is a lightweight RSS aggregator written in vanilla PHP.
There are several Web sites (Slashdot, for instance) that I visit regularly or semi-regularly to check for the latest news; there are also several more (like, say, the EFF) that post regular updates and that Id like to visit regularly, or that would like to have me visit regularly, but which I dont visit regularly because its just too much work to keep track of all of them, and too disappointing when I remember to check and find nothing new. I even run a Web site of my own which Id like to have people check regularly - but since I dont spend time making the rounds of my friends similar sites, I cant expect them to visit mine. Rippy the Aggregator aims to solve all these problems.
There is a standard called RSS, for Web sites to publish their updates in a machine-readable format. An appropriate client can quickly visit all the Web sites youre interested in, download their updates, and present you with a customized list of all the newest items. Most "blogging", "portal", and "content management" software already generates RSS files (although its operators may be unaware of that!), and there are services like Syndic8 that compile lists of RSS "feeds". So it only remains to get an appropriate client.
That presents a problem. I hacked an RSS output onto my Web-site updating scripts, so I had that aspect covered, but then I wanted to start reading others RSS feeds, and I discovered that the client programs you can get on the Web mostly suck. Some of them are Windows-only, so those are right out. I saw one in Java that looked pretty good, but its Web site didnt provide a way to download it except through some kind of weird Hot-Buzzy-Java-Scripted-Auto-Virus-Install-Plugin-Thing - there was no actual file. I did eventually find its source code, but it required third-party libraries.
Then I looked at several RSS readers that were written in Perl or PHP and designed to run as scripts on a Web site. Those had possibilities, but they required multiple third-party libraries (Perl) or an SQL server and compiled-in PHP modules that most people dont have (PHP).
The best attempt I found was one written in Python, but in order to make it run I had to start not one but two background server daemons, which would make it tricky to use on my office computer at school. There are Web sites that provide the service of RSS reading, but they all require registration, cookies, JavaScript, etc. I couldnt find an RSS reader (or "aggregator", as theyre called) that I could just download and have it work. Thus, it was necessary to create one: enter Rippy!
The name "Rippy the Aggregator" refers to an Arrogant Worms song about a cute, cuddly little alligator who goes "chomp, chomp, chomp," down in the bottom of the swamp, swamp, swamp. Abram Hindle has suggested that Rippy the Aggregator should go "grep, grep, grep," down in the bottom of the net, net, net. Anyone wanna write the rest of the song?
Main features:
- Cute name
- Written in PHP (needs 4.3.0 or above)
- Doesnt require any compiled-in optional libraries that dont ship with PHP
- Stores its cached data in flat files, no database needed
- Freely licensed and customizable under the GNU GPL version 2
Enhancements:
- Parser ruggedness and general stability were improved, and support was added for setting options like user agent and proxying when acting as an HTTP client.

The Linux Replicated High Availability Manager (aka Linuxha.net) allows the creation of clusters for application high availability through data replication.
Currently, clusters are limited to two nodes, but multiple applications can be hosted and failed-over between the nodes. The software uses DRBD to provide the data replication facillity.
Although this shared-nothing type architecture is typically more complex to configure and manage the Linuxha.net toolset attempts to manage much of this complexity for the administrator.
Much of the initial development and testing took place on various Linux 2.4 based distributions. More recently development and testing has taken place on Linux 2.6 distributions (primarily Fedora Core), ensuring the product works as expected on the latest available distribution releases.
Much effort has been spent ensuring that significant levels of support documentation is available. The documentation section now contains several guides as well as a user manual.
Please note that the user manual will eventually be replaced by a reference guide and various installation and user guides. Keep changing the documentation page regularly - these will be added when they are completed and aim to just cover specific topics.
Enhancements:
- Improvements were made to handling physical network link checking.
- Improvements were made for local IP fail-over.
- More flexible cluster partitioning handling was implemented.

Madagascar (formerly known as RSF) is an open-source software package for geophysical data processing and reproducible numerical experiments.
- a convenient and powerful environment
- a convenient technology transfer tool
for researchers working with digital image and data processing. The technology developed using the Madagascar project management system is transferred in the form of recorded processing histories, which become "computational recipes" to be verified, exchanged, and modified by users of the system.
Main features:
- Madagascar is a new package. It started in 2003 and was developed entirely from scratch. Being a new package, it follows modern software engineering practices such as module encapsulation and test-driven development. A rapid development of a project of this scope (more than 300 main programs and more than 3000 tests) would not be possible without standing on the shoulders of giants and learning from the 30 years of previous experience in open packages such as SEPlib and Seismic Unix. We have borrowed and reimplemented functionality and ideas from these packages.
- Madagascar is a test-driven package. Test-driven development is not only an agile software programming practice but also a way of bringing scientific foundation to geophysical research that involves numerical experiments. Bringing reproducibility and peer review, the backbone of any real science, to the field of computational geophysics is the main motivation for RSF development. The package consists of two levels: low-level main programs (typically developed in the C programming language and working as data filters) and high-level processing flows (described with the help of the Python programming language) that combine main programs and completely document data processing histories for testing and reproducibility. Experience shows that high-level programming is easily mastered even by beginning students that have no previous programming experience.
- Madagascar is an open-source package. It is distributed under the standard GPL open-source license, which places no restriction on the usage and modification of the code. Access to modifying the source repository is not controlled by one organization but shared equally among different developers. This enables an open collaboration among different groups spread all over the world, in the true spirit of the open source movement.
- Magadascar uses a simple, flexible, and universal data format that can handle very large datasets but is not tied specifically to seismic data or data of any other particular kind. This "regularly sampled" format is borrowed from the traditional SEPlib and is also related to the DDS format developed by Amoco and BP. A universal data format allows us to share general-purpose data processing tools with scientists from other disciplines such as petroleum engineers working on large-scale reservoir simulations.

CSS Briefcase project is simple tool that helps you organize CSS styles you use regularly. If youre frustrated writing the same CSS code for every project, or spend way to much time fishing around through old projects trying to find a key bit of CSS style code, this tool will help ease your woes.
Main features:
- Add CSS styles using a simple form.
- Generate CSS code by selecting the styles you want and clicking a button. Its that easy!
- CSS Briefcase takes care of some of the most common formatting issues in stride.
- Support for class-type styles, id-type styles and styles for pre-defined HTML tags.
- Data is saved in XML format, so no database is needed!

Klaverjas Score is a program to keep track of the scores during a game of klaverjas (a Dutch card game).

The program is meant to replace written score keeping, making accurate score listing much easier. It also keeps track of previous games.

Klaverjas Score is very suitable for small groups of people that play together regularly and that would like to have a record and comparison of their games.

mcelog decodes machine check events (hardware errors) on x86-64 machines running a 64-bit Linux kernel.
It should be run regularly as a cron job on any x86-64 Linux system (if it is not in the default packages on your x86-64 distribution, please complain to your distributor).
mcelog project can also decode machine check panic messages from console logs.
The latest x86-64 2.6 kernel wont log machine check errors to the kernel log anymore. You need this tool to decode them.
Create the device first.
mknod /dev/mcelog c 10 227
Enhancements:
- Modifier command line options are now allowed after --ascii.
- A decoded address is no longer printed twice for --ascii.
- The SMBIOS anchor scan was fixed to work on more machines and no longer crashes when no anchor is found. --ascii reparsing of mcelog output was fixed.
- NONE entries are not printed in SMBIOS.

This program is a daemon intended to catch someone installing a rootkit or running a packet sniffer. It is designed to run continually with a small footprint under an innocuous name. When triggered, it sends email, appends to a logfile, and disables networking or halts the system. it is designed to install with the minimum of disruption to a normal multiuser system, and should not require rebuilding with each kernel change or system upgrade.http://vancouver-webpages.com/rkdet/rkdet-0.54-2.i386.rpm
The program regularly verifies the checksum of a small number of system files that are typically modified by a rootkit. This list of files is compiled into the program. The file list, together with the system commands and messages, are obfuscated in the compiled code to prevent someone from figuring out what the program is for by eyeballing the binary.
The obfuscation algorithm is simple, but is compiled into the program and does not depend on external programs or other libraries.
The program takes a single optional numeric argument. If odd (bit 0 set), the interface "eth0" is checked for promiscuous operation (packet sniffing). If bit 1 is clear, the program will delete the default route on the network when triggered. Of bit 1 is set, the program will disable the eth0 interface. Systems with multiple interfaces may require an alternate interface specification in "xstrings.txt", or modification of the program to disable multiple interfaces. If bit 2 is set, the program will only log events and not disconnect the network.
The command may be modified to "init 1" or "shutdown -h now" if desired, or to run a script such as "panic.sh" (included).
Enhancements:
- Added configure script.
- Do not trap if checksum program fails (due to load, etc.)
