Hello Golfers!!!

Also, we have a new golfer mascot, but need a name for her. Reply below to help us think of a name!

Part 1 of my #BGGP6 writeup about nasm's most mysterious object file format, RDOFF.

n0.lol/bggp6-rdoff/

Today I got RDOFF (.rdf) files working in nasm 2.15. I wrote my own lib bc nasm didn't generate properly. Also patched the 32-bit loader in `rdx` with mmap tricks (shoutout ixi). An executable RDOFF has likely never run on a 64 bit system before today. Writeup soon! #BGGP6

Doing this again! This time I am looking into resurrecting an old object file format using scapy, and will probably look at some more entries for #BGGP6 . If you're working on any cool file stuff or just want to chat, come thru!

This weekend I'm thinking about chilling in the @binary.golf discord voice chat and working on some ideas for #BGGP6 if anyone else wants to play with weirdo files or just hang.

New writeup for #BGGP6 !!

What's the smallest Wireshark dissector? What's the most annoying Wireshark dissector?

I discovered that if you pass a hostname that curl can't resolve it returns 6 (everything.curl.dev/cmdline/exit...)

do with this what you will #bggp6 :)

running the 55 byte file named in the post with perl, shell, make, and dosbox.

#BGGP6 is off to a great start! We got 4 entries in the first 24 hours (as many entries as all of BGGP1!).

In the lead so far by total score is mauke, who made a 55 byte 4-way polyglot that is also a palindrome (pictured).
