Utils:

ssh

• obvious

mg

• debloated emacs
  • even smaller than nvi/nex!

tmux

• a lot of people don’t realize this is an OpenBSD project
• session retention

doas

• sudo feels horrible after using this for more than 2 minutes
• invaluable in ports

pf

• ironic that this is most popular outside of OpenBSD (PFSense)

ifconfig

• command line interface translates directly to configuration files

login.conf/login

• anything on PenguinOS seems insane by comparison
  • especially oom killer

vmm/vmd

• still in its early stages, but I love it

got (technically not an OpenBSD project, but adjacent)

• debloated git
• partial git compatibility

Library Functions/Syscalls:

pledge & unveil

• interesting new approach to jails
• set and forget, no interaction needed on the user’s end
  • with exceptions like chromium & firefox

strtonum

• far nicer than strto* functions in stdlib

malloc

• now with use after free and leak detection! who needs valgrind?
