Glove80 is an ergonomic split contoured keyboard designed and produced by MoErgo. I backed the Kickstarter just over a year ago and got the parcels Friday afternoon. I haven’t yet had a chance to look at them, so without further ado, let’s see how it is!

I finally got around to configuring my tiny Corne-ish Zen r3 keyboard. This is a discussion of the advantages, challenges, ease-of-use, etc. of using a 42-key split keyboard. It’s definitely portable and very useable, but there are some caveats.

What do you do if you need a pseudorandom number generator but don’t know anything about how to implement that and, crucially, don’t care how good it is? You could read some papers, but ChatGPT had been making waves for a while, so why not try that?

As part of my Ph.D. exploration on how we know the types we’re using model what we think they do, I decided to try to implement a constraint solver in Idris (technically Idris2, but Idris1 is deprecated at this point, so I use ‘Idris’ and ‘Idris2’ interchangeably).

If you’ve flashed an ISO to a USB-drive rather than the boot card of your SBC, is there any way to load the thing? Yes, but it requires a bit of digging around in a weird pre-boot environment…

Well that was wild! I was sitting in bed when it suddenly started wobbling from side to side. My first thought was that the fan had made it shake, but that didn’t really make sense in terms of the amount of shaking that was going on.

The best way to learn & understand a thing is to implement it. So let’s implement (a subset) of Idris2! This part is an introduction and covers some function exercises that will help later.

With Brexit, etc. health insurance when travelling has gotten a bit complicated and the application process is slightly confusing. So I thought I’d document my experience.

Intro This is yoinked from an answer I gave on the Idris2 discord where someone was confused about using IO when there was multiple functions involved. I’ve slightly restructured it, but it’s still basically the Discord answer verbatim.

One of the more difficult concepts in Idris, I’ve found, is proving things through dependent types. The ‘simplest’ introduction to this is probably the DecEq interface, which this post aims to introduce, explain, and implement.
