"Jag höjer tio varningens fingrar"
Regeringen förbereder ett 20-tal propositioner inom straffrätten under våren. Det är en anmärkningsvärt hög siffra. Henrik Tham, professor emeritus i kriminologi, menar att eftertanke och rättssäkerhet står på spel. #Krimpol #Brottslighet

A hacker known as Martha Root broke in and deleted three white supremacists websites at the end of a talk during the annual hacker conference Chaos Communication Congress in Germany.
Basically! Internally the @trynova.dev engine uses @boshen.github.io OXC parser and when encountering TypeScript it simply skips past it (type stripping, without a separate step) or in rare edge-cases like enums handles it directly in the engine.
Would like to thank jsconf.jp for giving me the opportunity to give my talk on tryandromeda.dev
At JsConf.jp @loading.trynova.dev introduces Andromeda.
Andromeda is a TypeScript-native runtime that uses the Rust-based Nova JS engine together with Oxc.
It aims to be web interoperable and is part of WinterTC.
This Sunday, I'm giving a talk at JSConf! That's pretty exciting

CHATGPT IS NOT AND WILL NEVER BE AN “OPERATING SYSTEM”, CALL IT THAT ONE MORE TIME AND I WILL STAB YOU
I'm trying out streaming my programming of Nova #JavaScript engine, come watch if you're interested in data-oriented design, bytecode compilers/interpreters, or #Rustlang in general.

The string it creates seems to be truncated and rounded to around ~32 chars when dealing with radix 3, but the bug exists for all radixes which aren't a power of 2. This makes sense because v8 doesn't use the faulty `DoubleToRadixStringView` when stringifying 2, 4, 8, 16 and 32.
@aapoalas.trynova.dev / Nova #JavaScript engine has received funding from NLnet's NGI Zero fund for developing the engine!
The funding is for bringing the engine closer to full Test262 compliance, and for developing the data-oriented heap design and proving its worth. Exciting times ahead!
It isn't an issue in Spidermonkey it seems

> BigInt(Number.MAX_VALUE).toString(3) === Number.MAX_VALUE.toString(3); false
We found a bug in v8 while developing the @trynova.dev JavaScript engine. I was implementing the Number.prototype.toString method when @aapoalas.trynova.dev found that v8 doesn't properly handle Number.MAX_VALUE.toString()!
Good luck!
I have baked mokkapalat (Swedish originated brownie-like dessert) for tomorrow's team meeting: I am thus fully ready to start my half year leave of absence after Friday.
Full-time focus on @trynova.dev Nova JavaScript engine, here I come!
Today we're thrilled to announce our effort to port the TypeScript compiler and language service to native code, gaining a 10x speed boost in build times and editor responsiveness!

There was a talk at EuroRust which I found quite helpful: m.youtube.com/watch?v=MjlP...
The "Resources" section of the dylint readme also has some good pointers.
I think every designer should write a love letter to a font at least once in their lifetime.
This is mine: A 150-year-old font you have likely never heard of, and one you probably saw earlier today.

Nothing yet, and what little we once had we removed to instead focus on the JavaScript part of the engine. But one fine day we hope to revisit the wasm parts of the engine.
Last year Jarred was told quite explicitly about WinterCG and he's been invited for quite a while it seems without attending. Would hope he finally listens and joins WinterTC soon.
Relevant post from Luca in response to a thread by Jarred on twitter:

The year is ending, and Nova JavaScript engine has gone from rags to fairly nice rags during this year. It's time to look backwards and forwards!

A feature-flag for disabling proxies (and perhaps other features causing these kinds of de-optimizations) and enabling faster non-gc paths for all of these would be very cool.
A callstack generated from the profiling of the execution. Shown are the most called symbols ordered descending.
The major problem of course is my rather simple and stupid algorithm which could be heavily optimized but it's still quite fast in all other modern and optimized JS engines. I also can't find any single major performance bottleneck engine-wise like I did for day 4 when profiling though.
Day five of Advent of Code 2024 using the @trynova.dev engine! Not entirely satisfied with my solution as it has a bunch of extraneous loops inside loops making it's Big-O at least O(N^3) and quite slow in the unoptimized engine.
