hm I don't like how Mastodon happily fully shows my last post about my new blog entry in the timeline, until it grabs the title card and generates the thumbnail for it, then suddenly it's too tall and it hides everything but part of the first line.

New blog post:
Yesterday I once again fucked up and used Min when I meant Max (a mistake I just. keep. making), so I wrote up how I solved the issue for myself (as well as fixing issues with parameter ordering for Clamp, Lerp, and others that take a range and value)

I don't know who needs to know this, but it turns out "Min" and "Max" are wildly different functions

You know that part of game development where you make, say, the player model better, and now the backgrounds look bad, so you make them better and now the effects are bad, so you fix them and now the player model is bad again?
I'm doing that right now, but with low-level systems

Hotter take add-on: if you believe that code is self-documenting and no comments are needed, randomly generate your names and see if that still holds

Hot programming take of the evening: variable/function/type/etc names are just luxury comments
Compiler doesn't give a shit what things are called, they're specifically for the devs' understanding

Back when I was playing around with programming language design I came up with a design for strings that I really liked, and wrote a little thing about it in case anyone else who is also working on a PL design wants to steal it:

Part 2 of "how to emulate fused multiply add" is up!
This one is about 64-bit floats (or, more accurately, the largest float type available to you)
https://drilian.com/posts/2025.01.02-emulating-the-fmadd-instruction-part-2-64-bit-floats/
Turns out there are a lot more edge cases in this one (the kind the papers tend to overlook 🙃

Honestly given who's going to be in power here in the US in a few weeks, I don't love that 2025 is 45²
It's just bad writing, find a more subtle way of foreshadowing

In my ongoing quest to copy over the techy things I wrote on cohost, here's my very niche post on how to emulate the "fused multiply add" instruction for 32-bit floats (64-bit one coming tomorrow)

Well shit, looks like I somehow set the RSS feed up wrong, it doesn't seem to have the dates right in my reader.
Does anyone have a good "look at this RSS feed on a local computer" app handy anymore? All I currently have set up is "upload it to the real site and wait a full day for Feedly to notice it updated" and I couldn't find anything super-obvious when I did a search

One thing I'm struggling with as I'm writing coding articles for my blog is the best way to format code such that it's readable on phone with a minimum of scrolling
maybe it's not really possible because, honestly, it looks like I'm getting ~40 characters per line on my phone which makes for really short lines

And now I've copied over one of the posts I wrote over at cohost (rip eggbug 😢) about C++17's hex floats and how to parse them if you're trying to read them in some other language (like C#):
