Some of the worst code of my life, created 20 years ago when I was a teenager, today posted openly on my GitHub, was reverse engineered custom chat server protocol, as I wrote my own client to replace the Java applet. And to have logs. The catch is... I didn't have any Internet connection. I was going to an internet cafe, logging onto the chat server, and chatting, while recording the connection with Wireshark. At home, I'd print the hex + ASCII connection dump on my dot matrix printer, and used a highlighter and ballpoint pen to mark the fields of the message packet. Then I'd code something around it, planned new tests, compiled a new version of the app and.... took it with me on a hard drive to the internet cafe to test next day, or next weekend. I think I was way smarter and goal oriented than I am today.
