Adding finishing touches to my next blog post: on cracking simple passworded binaries. πŸ”πŸ’»
But while playing around with OverTheWire, I had a surprise guest hack into my tmux session, and we had a nice chat!

Tomorrow I'll be instead talking about that instead. πŸ•΅οΈβ€β™‚οΈ

Stay tuned!

Hey fellow assembly learners. Just created my first blog post on GDB Debugging + Claude AI.
πŸ“ It’s a simple resource/idea for anyone looking to learn the fundamentals of assembly and debugging. Check it out at dreaming-of-dragons.blogspot.c and let me know your thoughts!

Newbie type Question for #z80 #assemblyprogramming types in case im missing it or doing it wrong.

Is there a quicker way to get both nibbles from a byte. Not a BCD though. So to take a byte in register a,put each nibble into hl i do some shifts to right then left and a subtraction.
Is there mabe a command im missing, some binary math invert wizardry or is this a acceptable way to do this.

After a solid amount of programming and a lot of debugging, both in local code and in game code, I released the BSD Socket extension for AMOS BASIC. It works around AMOS's limitations when calling networking functions, providing as smooth an experience as possible for AMOS programs to talk to other computers. You can get it from Aminet or from my code repository. It's been used in the Amiga game AQUABYSS for months now, which helped simplify the networking code greatly in the application.

...so I built a netcat-like client in 68k assembler, a language and paradigm I had never used before. It took quite a while to get set up and get a handle on how to structure code, call library functions, debug issues, and figure out the gotchas, and in the end I had a command like tool, written in assembler, that could talk to the C server I wrote earlier. I was ready.
