Just sharing one aspect of my love for the Fossil version control system (from the creators of SQLite) which I've used for 4+ years.<p>To install it - download a ~10 MB executable binary file, put it in your path, and you've got the entire system (version control, wiki, bug database, chat system, HTTP(s) server and web-based UI, email server, etc.). To upgrade it, copy the new binary over the old one.<p>This is exactly how software should be!<p>The rest of the industry lost its mind somewhere - containers bundling thousands of dependencies, separate builds for 100 different distros, DLL / .so hell, 200 MB Electron hello-worlds, etc.
