Using Lua from Go

↺ Using Lua from Go

> Last weekend, at FOSDEM 2023, I watched a Lightning Talk by Frank Vanbever titled "Lua for the Lazy C developer". I had recently suggested at work that we should be using Lua to script the behavior of some systems which are written in Go, so the talk strongly resonated with me. Lua is an ideal scripting language for embedding into other programs because it is small and provides excellent bindings in both directions – Lua code can call native code, and vice versa.

Hack Week 22: An Art Project

↺ Hack Week 22: An Art Project

> Back in 2012, I received a box of eight hundred openSUSE 12.1 promo DVDs, which I then set out to distribute to local Linux users’ groups, tech conferences, other SUSE crew in Australia, and so forth. I didn’t manage to shift all 800 DVDs at the time, and I recently rediscovered the remaining three hundred and eighty four while installing some new shelves. As openSUSE 12.1 went end of life in May 2013, it seemed likely the DVDs were now useless, but I couldn’t bring myself to toss them in landfill. Instead, given last week was Hack Week, I decided to use them for an art project.
