A spreadsheet widget for Gtk (an Excel-like table). gtksheet is a useful widget set complementary to GTK+ for creating graphical interfaces for the X Window System. It is split out of the old gtkextra library of the gtk2 era and ported to gtk3.

AppStream is a metadata specification which permits software components to provide information about themselves to automated systems and end-users before the software is actually installed. This permits informative displays of new applications to users in software centers, as well as allowing a system to make decisions on which new software a user might want to install (e.g. missing firmware or media handlers).

SMPEG (SDL MPEG Player Library) is a free MPEG1 video player library with sound support. Video playback is based on the ubiquitous Berkeley MPEG player, mpeg_play v2.2. Audio is played through a slightly modified mpegsound library, part of splay v0.8.2. SMPEG supports MPEG audio (MP3), MPEG-1 video, and MPEG system streams.

McXtrace is a tool for carrying out highly complex Monte Carlo ray-tracing simulations of X-ray beamlines to high precision. The simulations can compute all aspects of the performance of beamlines and can thus be used to optimize the use of existing equipment, design new instrumentation, and carry out virtual experiments for e.g. training, experimental planning or data analysis.

OCaml is an implementation of the ML language, based on the Caml Light dialect extended with a complete class-based object system and a powerful module system in the style of Standard ML.

Like other full-featured batch systems, HTCondor provides a job queueing mechanism, scheduling policy, priority scheme, resource monitoring, and resource management. Users submit their serial or parallel jobs to HTCondor; HTCondor places them into a queue. It chooses when and where to run the jobs based upon a policy, carefully monitors their progress, and ultimately informs the user upon completion.
