The polyglot developers dilemma is always the little things.

Whats the syntax for this common thing, that semi-colon is an error here, etc, etc

I'm encountering lots of little dilemmas today as I switch between #Swift, #Csharp and #GoLang.

I've written all these for years and after context switching I can’t write fizzbuzz

Day 11 of the C# Advent Calendar 2025: https://www.csadvent.christmas/

It's December, and as the final episode of this season, Eva and @0x_F0 build a Roslyn Source Generator polyfilling a Throw-Helper live, at 18:00 UTC.

Did I ever publicly mention I've been (slowly) working on porting my #Asteroidians codebase from #Unity to #Monogame ?

Apparently that started June. 🙄

I spent today working on my replacement Coroutine sys, which has gotten some 👀❓from the Monogame discord.

I have specific needs for Coroutines though, for running game-simulation code over-time with my "deterministic lockstep sync" based #multiplayer architecture.
And it keeps code tidy!

#AdventOfCode Day 11: Reactor

Wow, with 24 lines, this turned out to be the almost shortest and fastest code of this year for me. Enduring so many past AoC graph puzzles has finally paid off. I even finished both parts before breakfast. Okay, I’ll stop bragging now. There is still one more day to go.

Update: I played around with Cytoscape again. Attached is my puzzle input as a graph.

Red = svr (start)
Blue = fft
Lavender = dac
Green = out (end)

The puzzle input rendered in cytoscape. With the important nodes colored.

Want to know what my favorite design pattern is?

#AdventOfCode Day 10: Factory

Part 1 was easy, and I did it before breakfast.

But Part 2: Oh my! I tried to do it with combinatorics first, and it was too slow, even after countless optimizations. There is probably a dynamic programming way to do it, but dynamic programming is my nemesis.

I also figured early on that it was a linear systems problem, but linear algebra is ALSO my nemesis, so I avoided it at first. But since plan A didn’t work, I tried to solve the equations system myself in code with lots of Googling. But I eventually gave up and used a linear algebra package to do it for me (Google.OrTools.LinearSolver). Arghh...
