Planets is a fun, interactive program for many-body gravity simulations. The emphasis is on play: it's easy to add in planets, zoom in and out, change the physical constants, save and load configurations, etc. It's designed to be easy enough for a kid to enjoy, but that hardly precludes adults.
Active-DVI is a DVI previewer and a programmable presenter for slides written in LaTeX. The previewer features color anti-aliasing, inclusion of images with alpha channel and blending, encapsulated Postscript file inclusion, Gpic specials to display pictures, correct treatment of many inlined-Postscript specials, page background settings, and Japanese pTeX DVI extension support. To present your DVI files, it features basic effects for presentation (pause, delay, dynamic text color change), annotations displayed on demand (similar to pop-up balloons), hyperlinks from slide to slide or to other files, replay of previously recorded parts of the display, text movements, page transitions, embedded applications, and scratching on slide to interactively modify the text on screen. Its special effects are set and launched from within your LaTeX source file via the macros of the advi.sty LaTeX package provided by the distribution. In addition, Caml hackers can program new and fancy Active-DVI effects in the source code of the presenter.
Generally, mod_ocaml is a flexible apache module for use of INRIA's powerful OCAML interpreter as a Web scripting language (with functional and imperative features). Simply embed OCAML code between HTML on your pages, like you do with PHP, mod_perl, etc. After modifying some settings, you can use almost any interpreter for providing dynamic content on your HTML pages.
SKS (Synchronizing Key Server) is a full-featured replacement for the standard PKS OpenPGP Key Server. It matches all of PKS features and interfaces, and at the same time provides a highly efficient, gossip-based replication algorithm that ensures that the replication is complete.
Cameleon is an integrated development environment for Objective Caml and eventually other languages. Its features include a graphical user interface, configuration management based on CVS, easy access to and browsing of documentation, various editors, customizable file types, a plug-in architecture, and a highly customizable interface.
repasa is a set of three kind of tools: For creation of contents directly in the XML format of repasa or in other file formats (DocBook and LaTeX) following some conventions, for checking the contents, and for studying the contents and registering progress. The contents can be specified with definitions, classifications for the definitions (possibly along with exercises), and sequences of study. It is especially well suited to organize information according to the current legislation for education in schools of Colombia.
mod_caml is a set of Objective CAML (OCaml) bindings for the Apache API. It allows you to run CGI scripts written in OCaml directly inside the Apache Web server. However, it is much much more than just that. You can bind to any part of the Apache request cycle, read and modify internal Apache structures, share modules of code between handlers and scripts, or use the CGI library and templating system (allows separation of code and presentation).
Hamilcar is an XML application server inspired by Apache Cocoon for Objective Caml, using the Yaxi library. It is designed around the concept of a pipeline that is traversed during the processing of a request with control structures embedded in XML tags directing the process according to various criteria.
