Building native compilers is hard 🤣 Building bytecode VM / interpreters is way easier 🤣

@shinyoukai@neko.laidback.moe Very cool! 😎

@shinyoukai@neko.laidback.moe Nice! 👍

@movq@www.uninformativ.de Thanks! 🙏

@shinyoukai@neko.laidback.moe Nah it’s more like there’s a lot of repeated code, because when you go from source language to intermediate representation to machine code, well you just end up writing a lot of the same patterns over and over again. I need to dedupe this I think.

@kiwu@twtxt.net Ooof 😢 That’s rough!

The compiler technique I’m using here is to not “emit” most of the runtime if it’s actually never used in your program, and also dropping dead code in the SSA pass.

@movq@www.uninformativ.de I’ve managed to bring a simple “Hello World!” in mu (µ) (at least on macOS / Darwin / ARM64) down to ~86KB (previously ~146KB) 🥳

Hmmm I need to figure out a way to reduce the no. of lines of code / complexity of the ARM64 native code emitter for mu (µ). It’s insane really, it’s a whopping ~6k SLOC, the next biggest source file is the compiler at only ~800 SLOC 🤔

@movq@www.uninformativ.de I think I can get binaries even smaller with a bit more work and effort 🤔 But yeah still working on the native code generation (at least for macOS targets)

@movq@www.uninformativ.de Oh that’s fine, Mu can compile to native code and so far binaries. at least on macOS are in the order of Kb in size 😂

@movq@www.uninformativ.de It’d be cool if you could get µ (Mu) running in your little toyOS 🤣 You’d technically only have to swap out the syscall() builtin for whatever your toy OS supports 🤔

@thecanine@twtxt.net I see 🤔 Very cool though! 😎

@movq@www.uninformativ.de I watched a few of these thanks to you! Very cool shit™ 😎

@movq@www.uninformativ.de Ooof that’s chilly 🥶

that’s a whopping 36°C today 🥵

@dce@hashnix.club merry Christmas to you too!

@thecanine@twtxt.net Is it because you’ve used white pixels around it to sort of give it aht 3D look? 👀 Hmm? 🤔

@bender@twtxt.net It’s fun living in the future isn’t it 🤣

👋 Merry Xmas 🎄 🎅

👋 Merry (2025) Xmas y’all 🎄 Ho ho ho! 🎅

@movq@www.uninformativ.de From 2:50 PM to 3:23 PM AEST (+10 UTC) there was an outage. Everything went “up” on Down Detector, my EU region went offline, numerous sites were unavailable, and so on. Basically everything to/from the EU appeared to basically go kaput.

Hey EU friends 👋 wtf happened to the EU Internet today for about 40 minutes or so?

@movq@www.uninformativ.de @kiwu@twtxt.net it just so happens to be a happy coincidence that I’m extending mu’s capabilities to now include a native toolchain-free compiler (doesn’t rely on any external gcc/clang or linkers, etc) that lowers the mu source code into an intermediate representation / IR (what @movq@www.uninformativ.de refers to as “thick layers of abstractions”…) and finally to SSA + ARM64 + Mach-O encoder to produce native binary executables (at least for me on my Mac, Linux may some later?) 🤣

@movq@www.uninformativ.de Pretty sure all my mu solutions are very slow, but not so slow as I optimized most of the implementations to avoid as much brute forcing as I could.

@movq@www.uninformativ.de This is the total amount of cpu time consumed right?

@movq@www.uninformativ.de Hmmm 🧐

@kiwu@twtxt.net evening!!!

@movq@www.uninformativ.de Haha 😆

I cleaned up all my of AoC (Advent of Code) 2025 solutions, refactored many of the utilities I had to write as reusable libraries, re-tested Day 1 (but nothing else). here it is if you’re curious! This is written in mu, my own language I built as a self-hosted minimal compiler/vm with very few types and builtins.

https://git.mills.io/prologic/aoc2025

I finished all 12 days of Advent of Code 2025! #AdventOfCode https://adventofcode.com — did it in my own language, mu (Go/Python-ish, dynamic, int/bool/string, no floats/bitwise). Found a VM bug, fixed it, and the self-hosted mu compiler/VM (written in mu, host in Go) carried me through. 🥳

@movq@www.uninformativ.de I shrank Day 9 Part 2 from “cover the whole map” to “only track the interesting lines.” By compressing coordinates to just the unique x/y breakpoints, the grid got tiny. I still flood-fill and do the corner-pair checks, but now on that compact grid with weighted prefix sums for instant rectangle checks. Result: far less RAM, way less CPU, same correct answer.

Day 9 also required some optimizations, if you aren’t careful, you end up with really inefficient algorithms with time/memory complexity beyond what a typical machine has 🤣

Ooops, I’ve run into a bug or limitation with mu for Day 9 🤔

Day 7 was pretty tough, I initially ended up implementing an exponential in both time and memory solution that I killed because it was eating all the resources on my Mac Studio, and this poor little machine only has 32GB of memory (I stopped it at 118GB of memory, swapping badly!), This is what I ended up doing before/after:

• Before: Time O(2^k · L), memory O(2^k), where k is the number of splitters along a reachable path and L is path length. Exponential in k.
  
• After: Time O(R·C) (or O(R·C + s) with s split events), memory O©, where R = rows, C = columns. Polynomial/linear in grid size.

@shinyoukai@neko.laidback.moe Good 😊

I just completed “Printing Department” - Day 4 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/4 – Again, I’m doing this in mu, a Go(ish) / Python(ish) dynamic langugage that I had to design and build first which has very few builtins and only a handful of types (ints, no flots). 🤣

I just completed “Lobby” - Day 3 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/3 – Again, I’m doing this in mu, a Go(ish) / Python(ish) dynamic langugage that I had to design and build first which has very few builtins and only a handful of types (ints, no flots). 🤣

@shinyoukai@neko.laidback.moe Funny you should say that, I designed a new Prolog(ish) Symbolic Reasoning Engine and DSl over the holidays 🤣

Let’s see 😂

Did I mention mu only supports ints? 🤔 I’m not sure if I’ll need flots for this year’s AoC? 🤔

I’m having to write my own functions like this in mu just to solve AoC puzzles :D

fn pow10(k) {
    p := 1
    i := 0
    while i < k {
        p = p * 10
        i = i + 1
    }
    return p
}

I just completed “Gift Shop” - Day 2 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/2 – But again, I’m solving this in my own language mu that I had to build first 🤣

I just completed “Secret Entrance” - Day 1 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/1 — However I did it in my own toy programming language called mu, which I had to build first 🤣

That’s the right answer! You are one gold star closer to decorating the North Pole. [Continue to Part Two]

Whoo! Making progress! With AoC 2025 solutions implemented in my own toy language 🤣

Ahh that’s because I forgot to call main() at the end of the source file. mu is a bit of a dynamic programming language, mix of Go(ish) and Python(ish).

$ ./bin/mu examples/aoc2025/day1.mu 
Execution failed: undefined variable readline

Come back from my trip, run my AoC 2025 Day 1 solution in my own language (mu) and find it didn’t run correctly 🤣 Ooops!

$ ./bin/mu examples/aoc2025/day1.mu
closure[0x140001544e0]

And I’m back from my holidays! 🥳 Back to work boo 😒

@bender@twtxt.net agreed

@aelaraji@aelaraji.com probably a bug on my end with the bridge. I’ll figure it out with your help when I get home from my holidays.

@bender@twtxt.net that’s kind of what I was getting it initially yeah

@movq@www.uninformativ.de this is brilliant!

@movq@www.uninformativ.de @zvava@twtxt.net I think people get sick of everything changing all the time and so don’t bother adopting things to change when things are already good enough 🤷

Ba Na Hills and it’s basically clouds at this point 🤣

@movq@www.uninformativ.de I think WebP being new just hasn’t seen widespread adoption everywhere (yet) 🧐

i’m always open to suggestions: PRs also welxome 🤣

@bender@twtxt.net

@bender@twtxt.net No no we did!!! Just the photos are rubbish 😂

@movq@www.uninformativ.de Ahh you are a brilliant man 🙌

Went to Ba Na Hills today, but honestly it was so cold and misery i couldn’t take very good photos 🤣 Here’s a few shots i managed!

@movq@www.uninformativ.de BahahahGG 🤣🤣🤣

@klaxzy@klaxzy.net do you know what I also find equally just as stupid and dumb is having to upgrade the software license on something just to be able to get OIDC or OAuth support ffs 🤦‍♂️

can somebody please transcribe what he said and post it here? 🙏 I think it’s too good just to waste in a video it needs to be preserved. 🤣

Need to fix:

• threads
  -media and links

We’ll all my posts are making it to the “Fediverse” https://bridge.twtxt.net/users/c350a5e5fb9d9457

@bender@twtxt.net i’m just pointing out that it’s one of those fundamental RS 232 standards that will never die 🤣

@movq@www.uninformativ.de I think even modern PC still come with serial ports they just don’t wire them up anymore right? They’re still there in the board itself, though just unwired.

This is an example of the kind of garbage release notes from this conventional commit autogenerated crap 🤣

This ☝️ I proxy my SSH traffic and it requires a valid account check to occur.

@lyse@lyse.isobeef.org I couldn’t agree more! I think good commit messages are very useful, however, and I’d much prefer the conventional mood style for Commit messages, but rather prefer telling a story rather than this weird syntax all over the shop!

I kind of hate conventional commit messages: https://www.conventionalcommits.org/en/v1.0.0/#summary

but I am loving reading RFC 2119: https://www.ietf.org/rfc/rfc2119.txt

@movq@www.uninformativ.de Haha 🤣

Confirmed it’s called Tao Tao 🤣

@itsericwoodward@itsericwoodward.com Aren’t yhere onlu 12 puzzles this year? 🧐

@movq@www.uninformativ.de What about a drop bear? 🧐🤣😆

@shinyoukai@neko.laidback.moe Are you using your Gitea username instead of got@ ? Are you forwarding auth?

@bender@twtxt.net are you able to send me a video recording of how that sounds because I don’t think that that’s what they called it at the breakfast? 🤣

@movq@www.uninformativ.de well I’ve got several minutes of at least three people’s attention now didn’t it? 🤣

@bender@twtxt.net actually I think it’s a little more nuance than that because for example with salty chat, we have support for DNS based delegation via SRV records and your identity is associated with your Apex Dom name and of course the keys.

I actually don’t understand why Federation and activity pub is so goddamn hard to migrate from one instance to another 🧐

@bender@twtxt.net Same. I think i might have played with it at some point!

@bender@twtxt.net ha ha it started the V something and I don’t understand how to reproduce Vietnamese name 🤣

@shinyoukai@neko.laidback.moe what app is that?

@aelaraji@aelaraji.com does that mean your identity gets associated with your Apex domain or your sub domain?

it’s not an apple and it’s not a guava

@bender@twtxt.net LOL 🤣

@shinyoukai@neko.laidback.moe Yes! 🙌

@shinyoukai@neko.laidback.moe that has to be one of my stupid designs of activity pub 😆

I don’t know what this fruit is called! The waiter at breakfast told me the Vietnamese name but I’ve since forgotten 😂

@movq@www.uninformativ.de Yup did yjay some weeks ago 👌

@aelaraji@aelaraji.com I like the sounds of this technique a lot redirecting these AI crawling assholes to multi gigabyte files! The only concern I have is how do you do it in such a way that you don’t end up destroying your own ISP speed test servers?

@itsericwoodward@itsericwoodward.com So you’re found for Javascript eh? 🧐

@bender@twtxt.net Would you like me to say moar words ? 🤣

@shinyoukai@neko.laidback.moe carrying an MQTT broker isn’t exactly very simple though 😆

@kiwu@twtxt.net I’d recommend the one i linked you to a 2nd hand Sony 👌

Before smartphones people used to use the Sony Camcorders, but even though they still exist today, they’re uber expensive 😂

@kiwu@twtxt.net Only thing i can find that meets your requirements is the ORDRO HDV-V12 HD 1080P Video Camera Recorder Is 80m of video rexorsinimg enough for you?

@bender@twtxt.net Haha 🤣 I need a
good break after this insane year 😂
