Here is my list: - A server package containing: web server, smtp server, database engine, page generating language and a supervisor that keeps everything alive. All written in C and I use them for all server programming I do. - A file renamer that can rename multiple files. It puts the filenames in a text file and lets you edit it and then renames the files according to the changes. - A RISC-V start kit containing a very simple assembler, disassembler and documentation. - A script that runs twice a day and downloads things from the internet (like weather forecasts, news feeds, podcast feeds, train traffic info), puts them in a folder and does some processing and formatting. Then I can easily go through it all to get my daily information.
