gtk (115)

Automates most tasks on video and audio streaming. Besides being a free/libre software, its goals are:
  • Move past command-line based streaming, by automating things.
  • Provide audio/video feedback for the volunteer at the station to monitor the streaming.
Its current features include:
  • Behave slightly differently according to user actions or loss of the feed.
  • GTK+ graphical user interface.
  • Ease to switch between testing mode -- for testing the audio and video chain without broadcasting -- to stream mode, which broadcasts the feeds.
  • In the event of main camera source failure, ABYSS changes the pipeline to fetch the video source from a backup USB webcam and then starts broadcasting again.
  • Each stream is actually recorded locally in three forms to allow easy post-processing: audio-only, raw-video, and audio-video.
Was used during LibrePlanet 2015 and 2016. ABYSS was previously know as Libre-Streamer.
The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a library providing a non-interactive canvas where you can put common CAD entities such as paths, xatches and quotes, to create your technical drawings. The final result can be displayed inside a GTK+ widget or exported to any cairo available format, such as PostScript and PDF documents or PNG and SVG images.
Academic Teaching Planner
Academic Teaching Planner is a free software useful to plan university courses and various types of tests. It is designed as a personal tool beside management software used by academic institutions, and allows to: 1. manage and archive the documentation of each single course (objectives, bibliography, dates, information texts, lessons, files of all kinds, etc.) as well as the results of the tests, even the intermediate ones that are not always stored in management systems used by academic institutions; 2. manage the list of students who are enrolled in each individual course, easily retrieving their data from the management system in use at the academic institution, and their tests; 3. compare the distribution of bibliographic resources in the various lessons, made by the professor, with a reference model obtained by their homogeneous distribution throughout the course, to verify, also with the aid of diagrams, that the supposed planning is substantially realistic, that is, can be completed on schedule without omitting topics or lessons in excess. Academic Teaching Planner is a cross-platform software that runs natively on Linux, Windows and macOS. It manages data with Sqlite, a well-known and reliable database, while saving attachments (i.e. files of any kind associated with the various sections of the software) in an external folder, in a transparent way for the user. Their number and size are limited only by the space available on the computer in use. Academic Teaching Planner has been written with Lazarus ( and uses the Sqlite database through the Zeos components (
