Today's the 37th of #OctOpenBSD , so it's still legitimate to share my attempts to set it up on my rubbish old laptop: https://www.henryleach.com/2023/11/setting-up-openbsd-on-a-hp-stream11/ generally good, but suspend and hibernate don't seem to work quite right.

Dear #OpenBSD people, is there any noticeable performance improvement I can get in adjusting limits in sysctl.conf please? I’ve read various man pages: sysctl(2, 8), sysctl.conf(5), options(4) and seen people adjusting them in various posts, e.g. https://www.c0ffee.net/blog/openbsd-on-a-laptop#initial-configuration and https://i-bsd.com/openbsd-first-steps . But I can’t find anything that describes how to calculate them. This comment says they're only needed in very specific cases: https://www.reddit.com/r/openbsd/comments/exm01m/how_to_calculate_shared_memory_limits_and/ and there’s normally no point.

I am just astonished to know that using #QEMU I can boot up a VM from a img file as hard disk, and even literally a hard disk file such as /dev/sdc under #Linux. This way, I am booting my #OpenBSD on an external hard disk in #Debian. It's like magic!

I've been BSD-curious for a while, it's #OctOpenBSD and an old laptop needed a refresh, so naturally I tried installing #OpenBSD

Good news, it works! Now I've just got to try and configure it.

#OctOpenBSD

This is Ángel Ortega, crime and horror fiction writer and former systems programmer (on space, avionics and cryptography environments).

My first contact with a #UNIX system was on 1989 on a Sun Sparcstation 2 running #SunOS. I discovered #Linux on 1993 with the SLS distribution. I ditched all Microsoft software on 1999 and moved all my computers to Linux and never looked back.

My first encounter with #OpenBSD (inside a VM) was circa 2015. I was debugging a ground station software that was complicated as hell and had some memory leaks and was driving me mad; a friend of mine recommended compiling my beast on OpenBSD because the memory management is very different and it immediately crashed on a place I never expected. That filled my heart with bliss.

My first experience with OpenBSD in real hardware was on a laptop in 2020. Everything worked (except Bluetooth because, you know, there is no Bluetooth support on OpenBSD). I finally had to install Linux on that laptop because of reasons and my heart was a bit broken.

I now have OpenBSD on a tiny Toshiba NB 200. It's 32 bit, so no Firefox for poor old Ángel, but I don't really care because I used it mostly for fiction writing and remote server maintenance while on coffee shops, libraries or parks. Battery usage is great. Everything works like a charm.

I love OpenBSD because it's compact. It makes me feel like on a vintage UNIX system, simple and solid. Native tools and servers share lookalike configuration files. Man pages are awesome af. It includes a C compiler in its base system and that means "I am a real Operating System" to me. I love security is one of its main goals. OpenBSD hackers are brilliant, stubborn, unique people.

I don't love the filesystem.

I don't care that it's a bit slower than other OSes.

If you haven't tried OpenBSD, do it this October.

I just discovered the #octopenbsd hashtag, great initiative!
