BBP Pairings - Swiss-system chess tournament engine - LinuxLinks
BBP Pairings is an engine for pairing players in a Swiss-system chess tournament. It attempts to implement rules specified in the FIDE handbook. It is not a full tournament manager, just an engine for computing the pairings.
The program currently implements the 2025 rules for the Dutch system (the effective date for the rules was delayed to 2026). It also includes a flawed implementation of a previous version of the Burstein system. The implementation of the Burstein system has not been endorsed by FIDE.
The program’s interface is designed to be very similar to that described in the advanced user manual for JaVaFo 1.4.
This is free and open source software.

fre - track your most-used directories and files - LinuxLinks
The primary difference is fre does not support jumping. Instead, it just keeps track of and provides sorting methods for directories, which can then be filtered by another application like fzf. Additionally, it uses an algorithm in which the weights of each directory decay exponentially, so more recently used directories are ranked more highly in a smooth manner.
fre is primarily designed to interface with fzf. For general usage, a user will create a shell hook that adds a directory every time the current directory is changed. This will start to build your profile of most-used directories. Then, fre can be used as a source for fzf
