Openbsd on Andrew Quinn's TILs

LLMs make Perl great again

Sat, 24 May 2025 00:00:00 +0000

Perl 5 went through a long nadir of unpopularity due in large part to its deserved “Write Once, Read Never” reputation. So I was surprised to find out not only is it installed by default on Debian, it’s installed nearly everywhere by default. It’s even the non-shell scripting language of choice on OpenBSD!

Perhaps the only thing more impressive than Perl’s utter ubiquity is its longevity. The latest major version of Perl was first released in 1994. It came into existence on this planet less than a year after I did. It’s even arguably more portable than the median shell script - different Unices might use Bash, Zsh, Ksh, or even something newfangled like Fish, but for the most part a Perl 5 program is a Perl 5 program is a Perl 5 program.

OpenBSD, the computer appliance maker's secret weapon

Between our ESP32 prokaryotic organisms and our 24/7 Internet-enabled megafauna servers, there exists a vast and loosely-defined ecosystem of things the B2B world likes to call computer appliances. Picture a bespoke Pi 4 packaged up neatly with some Python scripts, a little fancy plastic embossing, and maybe a well-guarded id_ed25519.pub in case you end up in hot water during the (long - very long, stable cash flow for generations long) maintenance contract, and you’re in the ballpark.

tmux is worse is better

tmux (short for “terminal mux” (short for “multiplexer”)) is i3 for your terminal. Oh, it’s so much more than that, and I recently discovered with some joy that it is installed by default on OpenBSD, but its fundamental value add to any programmer who has to SSH into servers more than once a week is it allows you to split your screen up into multiple independent shells without needing a graphical environment at all. If you want to walk the path of true digital minimalism, vanilla Vim and tmux or its spiritual grandfather screen are all you need.

I'm turning 30 so naturally I'm switching to OpenBSD

Sat, 04 May 2024 00:00:00 +0000

I’m kidding, I’m switching to OpenBSD because I like security or code quality or something.

It’s totally not because the inexorable march of aging is starting to show its effects on my ability to down necessary-evil trivia like me and my friends used to down forties in the Ahhhnald after dark, and so I’d like to settle down with a software ecosystem I can study in real depth once without feeling like 20% of what I absorb in year X will be deprecated by year X+10.
