TorrentTrader provides a PHP-based Tracker application for the BitTorrent P2P protocol.

TorrentTrader allows anyone with a Web server supporting PHP and MySQL to run their own BitTorrent tracker. Also offered is a lite edition that does not require MySQL.

"It is an open-source project, which I have been in charge of from summer 2004 to summer 2005. Though I am no longer in charge of this project, you can find here for download the versions I have released."

Servlet is a Perl Servlet API v2.3

The Servlet API for Perl (libservlet) is a formulation of the Java Servlet API in Perl. The current version of the API is 2.3.

While the servlet concept originated with Java, its component model is quite natural for Perl as well. By writing servlet applications and deploying them in a servlet engine, application authors can spare themselves the effort of writing commonly needed web application infrastructure components for each new project.

Furthermore, servlet applications are portable between deployment environments; they can be executed in any servlet engine using any process model with only a few configuration changes and no application code changes. Servlet applications are insulated from changes in vendor or platform and are able to portably take advantage of standard web infrastructure services offered by any servlet engine.

CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by a prominent North American Enterprise Linux vendor.
CentOS conforms fully with the upstream vendors redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.) CentOS is free, however, we ask for a small contribution. CentOS is a project of the cAos Foundation.
CentOS is developed by a small but growing team of core developers. In turn the core developers are supported by an active user community including system administrators, network administrators, enterprise users, managers, core Linux contributors and Linux enthusiasts from around the world.
CentOS has numerous advantages over some of the other clone projects including: an active and growing user community, quickly rebuilt, tested, and QAed errata packages, an extensive mirror network, developers who are contactable and responsive, multiple free support avenues including IRC Chat, Mailing Lists, Forums, a dynamic FAQ. Commercial support is offered via a number of vendors.
CentOS exists to provide a free enterprise class computing platform to anyone who wishes to use it. CentOS 2 and 3 are fully compatible rebuilds of RHEL 2 and 3 respectively. CentOS 2 and 3 are reproduced from RHEL sources that are freely distributed by RedHat.
Redistributed packages and sources comply fully with RedHats redistribution requirements. CentOS 2 and 3 are designed for people who need an enterprise class OS without the cost, support, certification, or brand name of RedHat.
Main features:
- easy maintenance
- suitability for long term use in production environments
- friendly environment for users and package maintainers
- long-term support of the core
- active development
- community infrastructure
- open management
- open business model
- commercial support - offered by a partner vendor

PicoStorage allows you to store hierarhical information (similar to "files and directories") inside a single file. The functionality offered is largely equivalent to the one offered by any filesystem, or by the Structured Storage and Compound Files.

PicoStorage can efficiently handle huge numbers of small files, with very economical disk usage; it also allows you to keep open (in RAM) simultaneously a large number of files. Transaction support guarantees data integrity.

Learn more about the distinctive advantages of PicoStorage. or look at the benchmark.

The library is available on a dual-license basis: under GPL for free, and under a commercial license for use in closed-source applications.

Using

The library contains the classes File and Dir to represent files and directories. On a File you can read or write a number of bytes from a given offset, and set/get the file size. On a Dir you can create entries (either files or subdirectories), open entries, delete entries, and iterate over the directorys content.

The storage itself (i.e. the whole hierarchical structure, contained in a filesystem file) is represented by the class Storage. Using this class, you can create or open a storage, obtain the root directory of the storage, close the storage and do commit or rollback.

VSOFont is a small library used to draw very simple and fast user definable 2D vector fonts. At some point in time, when working with handheld devices, the font functions GLUT offered proved to be too massive. so i decided to write a very simple 3D vector text system using OpenGL myself. The application is coded in ANSI C.
Enhancements:
- added vsofont_read_font_from_memory().
- changed vsofont_read_font() to vsofont_read_font_from_file().
- example shows now how to draw a bolded string.
- VSOFONT header file should now work in C++ projects.
- small optimizations here and there.
