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?

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!

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 :)

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.

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!

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.

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.

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

My #JavaScript SoA adventures are bearing fruit: a test creating a data flow graph of 750k nodes, 250k graph entry/exit points ("inputs"), and who knows how many inputs not participating in the graph, it takes <400ms to run. That's ~400ns per node or input, which is pretty cool I think!

This weekend I've been (aside from suffering from a flu) having entertaining discussions and semi design sessions on in-place initialisation, out pointers, and such stuff in #Rustlang. It's really quite fun stuff to consider... Maybe there is a place for coroutines in all that as well?

Continuing on my crackpot theories of contravariant lifetimes, here's an interesting alternative formulation of Rust Pin: a pinned type holds a reference to itself (potentially inside a PhantomData). Moving the item invalidates that reference, so it invalidates the type.

AapoAlas @aapoalas.trynova.dev · 09/01/2026

trynova.dev/blog/garbage... Last Sunday I discovered that lifetimes on #Rustlang garbage collected handles should be contravariant on their lifetime parameter. This is an open research question, but I think this opens a path to meaningful lifetimes on self-referential structs. Check it out!

I'm being a total nutcase, but I found what I think is an important discovery about modeling garbage collected handles to the #Rustlang borrow checker: the lifetime of GC handles is contravariant! Instead of validity "rising up the call stack" it "droops down from the heap". Blog incoming!

In news related to my recent posts, are you a browser engineer? Should I move a virtual scrolling subgrid window using relative positioning and translate, defining a 50 row grid within (columns is subgrid), or should I define a 10x1500 grid at the top level and use grid-row to move the window?

110

AapoAlas @aapoalas.trynova.dev · 19/12/2025

That's some smooth scrolling! This is a list of 16000 items with a virtualization window of 48 rows, 24 visible, and 10 columns, scrolled at top speed using middle mouse click. Each frame at least 6 rows have their contents and order property changed, and the window is shifted using translate.

AapoAlas @aapoalas.trynova.dev · 18/12/2025

I obsessed over this a bit more, and found a way to make this into a two-axis scrolling grid! The linked trivial example doesn't have virtualisation, but that's mostly trivial to add in. This is pretty awesome! I have a feeling this'll see some use in the future. gist.github.com/aapoalas/a47...

So here's a #javascript #typescript #css thing I've been obsessed with over the last few days: a virtual scrolling grid using zero a single relatively positioned element and otherwise letting the browser lay everything out. Here's how: a grid of N columns, and a header row and contents row.
