paip-lisp
Lisp code for the textbook "Paradigms of Artificial Intelligence"
paip-lisp is the Common Lisp source code companion to Peter Norvig’s book Paradigms of Artificial Intelligence Programming. It contains implementations and examples from the book, covering classic AI techniques through Lisp programs. The repository includes systems for symbolic reasoning, search, rule-based inference, natural language processing, pattern matching, logic programming, and game-playing examples. It is valuable for readers who want to study the original code while working through the text or revisiting older AI ideas. The code also serves as a historical reference for how AI programming was taught before today’s deep-learning-centered ecosystem. paip-lisp is best suited for learners interested in Lisp, symbolic AI, and the foundations of practical AI programming. -

Nyxt
The hacker's power-browser
Out of the box Nyxt ships with tens of features that allow you to quickly analyze, navigate, and extract information from the Internet. Plus, Nyxt is fully hackable- all of its source code can be introspected, modified, and tweaked to your exact specification. Navigate large documents with ease. Utilize the power of running commands against multiple objects to avoid repeating yourself. You can select and close all buffers that match the string "ele". Fuzzy search-relevant commands to instantly run them. No more digging through menus. Use fuzzy search to instantly switch between buffers. No more hunting! Use link hinting to quickly jump around. Jump to a link by URL, title, or shortcut. Use the built-in REPL to program Nyxt. Run short scripts, and try out new workflows. Everything in Nyxt is fully extensible and modifiable. Smart bookmark search. -

ARITA
Extraordinary audio player for FreeBSD & GNU/Linux
Unlike conventional audio players, ARITA aims to help music lovers to keep their precious collections well organized and tidy. Therefore it takes a different approach to arranging audio files. They must be emplaced into libraries: 'archives' or 'cuesheets'. Archive - compressionless container like CPIO. Instead of tags for description of tracks, a plain XML/YAML file is placed alongside each archive. Rather than embedding cover art in every track, put a single image next to a library. TIFF supports multipage docs, so scans of covers/discs can be packed together in one file. ARITA will locate and display the said file, allowing you to view all pages. Optional 'signature' files can be created to keep checksums of tracks, so you may ask ARITA to verify them and make sure nothing is damaged due to a sudden failure of HDD/SSD. As for 'cuesheets': tracks are merged into a single continuous audio file and a supplementary text file, which provides information on where tracks start and end. -
