Below are a few pieces of code available as Libre Software. What you are seeing here is probably outdated, though.
3.2 GNU Guix
3.3 GNU Guile
Scheme is my programming language of choice and GNU Guile is currently my implementation of choice. It's probably not the best libre implementation of Scheme, but I find it quite friendly, it has one of the coolest module systems, it implements a lot of SRFIs, and it may be easily embedded in a C application.
I contributed little thingies for Guile, like Guile-Reader.
3.4 GNU Guile Networking Packages
Networking packages for Guile 1.8 that I wrote:
All these are available in their respective on-line repositories.
Technically, Skribilo is based on the Scheme language. It provides some sort of a simple markup language, not unlike HTML, DocBook, LaTeX, or Lout (see the meta-chapter for a demo!). Alternatively, it also offers a simpler, markup-less, plain text syntax that is comparable to that of, e.g., txt2tags, PlainDoc, and similar systems.
Skribilo derives from Skribe. It strives to be more modular and comes with new engines and features.
3.6 Typesetting with Lout
Lout is a free document formatting tool, similar in principle to TeX/LaTeX, but much more lightweight, clear, and easy to understand. Below are pieces of information that might be useful to Lout users.
3.6.1 Margin Kerning
Margin kerning is a micro-typographic refinement that is nice to have. Basically, it consists in protruding small characters located next to a margin outside the margin. This way, the shape of paragraphs looks better to the human eye. More information may be found in Micro-typographic Extensions to the TeX Typesetting System, by H. T. Thàn. Examples:
Update: This feature has been integrated in Lout 3.31, dated Aug. 24th 2005.
3.6.2 Computer Modern and Latin Modern Fonts
Here are useful pointers and pieces of information to use Knuth' beautiful Computer Modern fonts (you know: those LaTeX uses by default) in Lout. Note that these steps are detailed in Valeriy E. Ushakov's essay on the use of fonts in Lout (although the fontdef thing is deprecated since Lout now uses the @FontDef symbol for font database entries). The Type1 Computer Modern fonts are provided by the AMS and are available by FTP. Original CM fonts do not contain accented characters so you might need to get the Latin Modern fonts available right here.
Converting to the ASCII Type1 font format (PFA), which is
the format understood by
(see below), can be done
as follows, using the t1ascii
program from t1utils:
3.7 Ego+Pego: Portable Checkpointing for C/C++
A technical report that deals with the use of computational reflection in order to provide portable checkpointing facilities to compile C/C++ applications: PDF. These ideas have been implemented as two C libraries called Ego (which provides introspection facilities) and Pego (which provides state capture facilities). Whenever it's reachable, you can look at a dedicated webpage.
3.8 Libre Software Meeting
Thomas Petazzoni and I were volunteers in charge of the Operating Systems Design and Implementation topic of the 2005 Libre Software Meeting. LSM 2005 is now over. Papers, slides, and audio are available online.
I used to maintain software in my firstname.lastname@example.org GNU Arch archive (note: older archives can be found by just changing the year in the last component of the archive URL). However, I recently switched to Git for most of the software I maintain.
