iiinova — where your digital self keeps evolving

I've sort of assumed it's not done because of safety considerations, but I'm not sure.

AapoAlas @aapoalas.trynova.dev · 28/08/2026

Is there any way to cut the Gordian Knot: get WebComponents to render correctly without complex de-shadowification logics, use the native browser print for speed, but avoid blocking the entire website while the user fiddles with their print settings?

AapoAlas @aapoalas.trynova.dev · 28/08/2026

Doing that also takes a ton of time so it's not exactly efficient. The native browser print is lightning fast, but if you use print() to trigger it then you get blocking - and for some applications that is a critical safety issue. Conversely Ctrl+P does not allow for any async work before printing.

AapoAlas @aapoalas.trynova.dev · 28/08/2026

You can make a copy of the HTML (or the DOM structure and calculated styles) and open it in another window, but it will have to import the WebComponents to render them correctly: that requires JS, at which point CORS/CSP will stop you. Same thing with using pdfjs or equivalent.

AapoAlas @aapoalas.trynova.dev · 28/08/2026

Internet, I need your help with #HTML, #JavaScript, #WebComponents, and printing! So you know how the print() method blocks while the dialog is open? How do you deal with that in an application where you have user expectations of a print button (to select what is being printed), and WebComponents?

If you're interested, I can recommend (as a not-really involved party) the Oxide Computer company's Hubris OS for comparison: I think the repo includes all firmware to run their rack with the exception of the AMD CPU bootup related stuff. The amount of unsafe code was below 5% IIRC.

Rewatching Hikaru no Go for the first time in ages (though I've read the manga every year or two) is such a nice experience <3 Makes me want to play again! But first I should finish my two go boards!

All according to keikaku! TL note: keikaku means "plan".

No, just JS things: ~100 bytes on temporary objects (immediately passed to a Node addon so necessarily created) that can be replaced with a mutated singleton, ~150 bytes on replacing a normal function + context based capturing with a class instance with explicit capturing and .bind(this).

It is great to hold our new book - Cultural Game Studies - on one’s hands, even if the Open Access pdf version will most likely be the most used edition. - Link to the Open Access book page below: www.taylorfrancis.com/books/oa-edi...

A smallish refactoring in a Node.js server application saved me 272 bytes per HTTP request. That's pretty nice, I think. Or at least it made me happy :)

AapoAlas @aapoalas.trynova.dev · 06/08/2026

I think the answer is "no, but it's a prerequisite for fixing it". Either that or it was next-gen trait solver (also close to nightly merge) that would fix it...?

010

AapoAlas @aapoalas.trynova.dev · 03/08/2026

Roughly yeah. (And oops, that was supposed to be BaseClass.) But because Rust has (currently anyway) subobject provenance for references, it's more like a `NonNull<dyn BaseClassImpl>` where BaseClassImpl is the trait defined by the BaseClass's virtual methods.

010

AapoAlas @aapoalas.trynova.dev · 03/08/2026

TIL in C++ `BasClass&` can be created from a `Derived&`, thereby it does dynamic dispatch through the vtable instead of the reference being a guarantee that static dispatch is enough. Huh. This proves to be a mild issue with my C++/Rust interop crimes.

120

AapoAlas @aapoalas.trynova.dev · 01/08/2026

People don't change: in my Rust/C++ interop crimes I wanted to build an enum over "one-shot Request" vs "multi-response Request" even though both are just a C++ Request object at its core. An epiphany: this is what I always do in TypeScript as well! No wonder it felt so familiar and safe!

AapoAlas @aapoalas.trynova.dev · 31/07/2026

Indeed, Rust has untyped memory so it's for instance correct for &usize, &*const T, &f64, &(bool, u32) and even I think &Cell<u64> to all alias at the same time: the Cell is questionable as any mutation would have the other references see mutations under & and therefore UB. Rust memory = just bytes

AapoAlas @aapoalas.trynova.dev · 31/07/2026

Oh, I had completely missed that gccrs is also a thing and aims to become a complete Rust compiler in the long term as well.

020

AapoAlas @aapoalas.trynova.dev · 28/07/2026

That's definitely true. Somebody (possibly a little ... sitting sideways on their rocker?) should start a real competing Rust compiler I guess :D Though I guess arguably krabby could become a competing compiler.

010

AapoAlas @aapoalas.trynova.dev · 28/07/2026

There is a smattering of projects of various aims and sizes: mrustc, dozer, and krabby at least.

AapoAlas @aapoalas.trynova.dev · 28/07/2026

Not sure if relevant, but have you seen Anneal? It's a project combining Rust and Lean.

AapoAlas @aapoalas.trynova.dev · 28/07/2026

I don't know, but you _might_ enjoy gc-arena: it's more about GC than async, but it's implemented as a pre-empting system that produces what I think is similar to Go's asynchrony. Of course it is much more verbose than Go itself would be - maybe Rust coroutines might eventually help with that?

110

AapoAlas @aapoalas.trynova.dev · 20/07/2026

What's that? Also, the crimes are unfortunately in closed source (aside from that library that I wrote over a weekend day).

Life and people are weird, gotta just accept it all and say thank you at the end :)

AapoAlas @aapoalas.trynova.dev · 20/07/2026

It's quite the thrill, I say. I already started a library to make std:: function creation cross-platform, and now I'm honestly thinking I might need a library that auto-mangles function signatures into link_name attributes. Now that'd be fun!

So lately I've been having obscene amounts of fun during absolutely hair-brained and -raising FFI crimes between Rust and C++. "Look ma, no C ABI!" Just going in raw, binding to C++ ABIs, inheriting C++ classes, creating C++ template instances like std::function's, all that good jazz direct in Rust.

As a full-on Rust user: Zig is really good and I want to steal their best parts for Rust. I also hope they steal the best parts of Rust for Zig, though it seems that is not really what they want to do.

AapoAlas @aapoalas.trynova.dev · 20/07/2026

Huh, that really is the issue name. A bit combative if you ask me, but I'm a big wuss after all :D

AapoAlas @aapoalas.trynova.dev · 20/07/2026

Hopefully I can make the case at my work place in the future as well :)

AapoAlas @aapoalas.trynova.dev · 20/07/2026

Also, if you're a company using Rust then please consider donating to the project. A personal recommendation: the next gen trait solver and Move trait work could perhaps use some targeted funding. That work has the possibility of massively improving async code ergonomics <3

AapoAlas @aapoalas.trynova.dev · 20/07/2026

On the reviewer side (libs, not compiler though) I must say I wouldn't appreciate big LLM PRs explained with volumes of text and whatnot. But also: hell yeah if we got more high quality performance optimisation contributions in the compiler! LLM-based or otherwise.

So I'm taking a choir conductor camp, and in the same music camp is a man who is a total doppelganger of a coworker of mine, like not just looks similar but they really look like a clone sometimes! Turns out: they're identical twins. I guess that explains that.

AapoAlas @aapoalas.trynova.dev · 23/06/2026

I should really read that one. I forgot to order it

Oh boy, it's such a great book! My absolute favourite. When I finished it originally I just had to send the author a thank you note on Twitter: too bad it wasn't her but some British athlete. Luckily later I got the chance to deliver the note though a friend <3

AapoAlas @aapoalas.trynova.dev · 20/05/2026

Out of context: yes! Power to your ass!

AapoAlas @aapoalas.trynova.dev · 14/05/2026

Someone also had done a cloc comparison which discounted comments and found that the new Rust code had quite a bit more comments, as perhaps expected of LLM output.

So in other news today, I had a terrible/fun time with figuring out printing of WebComponent elements in response to a user button click without blocking the event loop! Can't use print() because it blocks, can't use iframe.src URL because it loses DOM state. Painful world out there!

This paper finds that Rust on an microcontroller costs you about 10% extra flash space, actually saves you a bunch of RAM, and takes no extra time to deliver (as compared to C). Seems about right - especially as the C version needed a heap and the Rust version did not. arxiv.org/pdf/2604.25679

Yeah, not that I'm massively experienced in this area but just like exceptions are (I assume) hard to reason about due to being "implicit" in the code, unwinding is too. Rust std does a great job of thinking about unwinding usually, eg. see Vec::retain_mut, but it's easy to forget still.
