If I say that, like, a thrown Exception won’t be caught. Or a method will be called on a null Object. Nobody panics. Because it’s all part of the *plan*
But if I say one little ol’ `Err` will be unwrapped? Well then everyone LOSES THEIR MINDS

Oh isn't is just so wonderful to write Rust wrapper crates for C?
Turns out C enums are `u32` on linux and `i32` on windows, so now I have to add a platform dependent cast.
Or rather: goodbye windows build.

The fact that AI coding assistants can even exist at all is a damning sign that we all spend far too much time solving the same problems over and over

Does anyone still do Intel macOS?
Does anyone do ARM64 Linux?
(Does anybody even do windows, in bioinformatics?)
I kinda want to only release for x64 linux and apple silicon... just to reduce bloat.

@wytamma.bsky.social : so, it took a little bit of extra time (not the flight back from the CZI meeting), but I decided to just f#&$ing do it, and the basic code to build and parse with the auxiliary fastq index is working (github.com/COMBINE-lab/...). 1/2

Daily reminder that you are a better writer and researcher than any generative AI platform around. Your skills are worthy and it takes far more time to clean-up and fact-check the mess some chatbot spits out than to just do it yourself 😘

film photography is worth it just for the novelty of being able to use the phrase "the lab" in casual conversation
tell me you don't feel a little bit like a character in a detective drama when you get to say "I gotta get this to the lab"

Somehow reading and writing memory is very asymmetric:
To read, you must first ask the memory for the data, and then wait for it to come back.
To write, you just send it and then forget about it.
This is probably why radix sort works so well: scattering data is super parallel :)
