I write code for fun, and for profit.
Also working on something (not so) exciting for the Fediverse.

That said, there are some things that I just won't allow me to cross post.
And that's being character limit.
My Mastodon instance has 1024. A blog post is almost unbounded.
Bluesky? Just 300.

I'm exploring the use of on-device AI, instead of delegating things over to a third-party.
I feel so proud of myself for thinking at that level.

The overall attitude on X (formerly known as Twitter): "if you're not hustling, you are doing something wrong". Everyone seems to be bullshitting somehow.

Now onto adding actual functionality to see how it impacts performance.

I keep telling myself that I'll use Bluesky more, but I can't seem to bring myself to do so.
Gotta start doing so.

Us developers have learned the hard way that:
1. Prototyping is more like 10% of the actual work - even though the business folks thinks we're 90% done
2. Shipping prototypes to production is possible but generally a bad idea
Vibe coding is prototyping. Others will learn - soon

Still thinking about the time Don Knuth complimented my font choice for my slides. (That was before he knew I made the slides in Keynote. He hasn't spoken with me since.) 🧮

TRANSFER MATRIX METHOD
Building games(P x [n]) one layer at a time
If G is a weighted graph with adjacency matrix A(G), then the entries of A(G)^n count the weight of length n walks between vertices.
Define G(P) to have vertex set games(P) and a directed edge QQ' with weight the number of matchstick games on P x [1] with Q on 'bottom' and Q' on 'top'.
For A(P) := A(G(P)), we have
games(P x [n]) = sum_{Q,Q' in games(P)} (A(P)^n)_{Q,Q'}.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ysaiuavm2f7d4th42c4valhw/bafkreie2jknw5sbb54v5qdy5wcpc22muwqdev7lzbdr3ipio7usqfy7hci@jpeg)

Dressing up the most boring coefficient possible, 1, as two Greek letters is pretty incredible
This earnest reaction from Joe Scarborough is the actual reason the White House tried to hide their completely bogus tariff calculation behind fancy Greek letters.
I also simply stopped reading and skipped ahead when I got to the Greek letters portion of the tariff press release.

i tried nix for the first time 2 years ago and I've given up on using it as a package manager locally (I just went back to homebrew), but I'm still using NixOS. Even though it's very confusing it still feels like the easiest way for me to manage a server

Nice short read this morning. I wasn’t super familiar with CBOR before getting into AT Protocol stuff.
Begrudgingly choosing CBOR over MessagePack
Protocols are important. Communicate with caution.
