@anisp @lumi @AerynOS sorta but it's way faster and therefore less annoying to use. see https://mastodon.online/@YaLTeR/116770771778033619RT: https://mastodon.online/users/YaLTeR/statuses/116770771778033619

I have successfully performed a manual @AerynOS installation on my laptop! (because the installer doesn't quite understand LUKS yet)Turned out fairly straightforward, just follow the commands that the installer runs. Also thanks @lumi for a write-up on how to do it.

what worked (suggested by CryZe) is assigning the PR from the issue's page (so the other way around)wonder if it only worked because the PR is new and at the top of the list. you know, in case it only loads the few newest ones..

Today niri became 3 years old! 🎉️ :blobcat: I merged the Smithay upgrade which brought a bunch of fixes and tablet grabs: https://mastodon.online/@YaLTeR/117061055221948130And I also implemented and merged animations for windows moving between workspaces!This was probably the last *major* missing animation. It's been in the backlog for so long because it's tricky with regards to Z ordering (moving windows need to be on top of everything), clipping, and needs sync between three different animations.#niri #smithay

apparently cachyos has -git packages which are not actually building the latest git, but are manually updated. so yesterday i fixed two deadlock regressions in niri, but cachyos users are still hitting them because their "git" package isn't updated from 2 days ago...

do we have a good way in GNOME to "view all images AND videos from a folder sequentially"? say you went on a vacation and shot a bunch of pictures and videos on your phone, then you come back and want to show them all to family. something like what a Google Photos or phone gallery apps provide, but on a big screen on my desktop, from a local folder#GNOME #linux

pov: writing a custom scrollable widget
(DIR) Post #B9cocvsgazMqd6VuIy by YaLTeR@mastodon.online

My experiment to write a custom GtkScrollable instead of GtkColumnView to get rid of a bunch of widget performance overhead.All of these are still real PangoLayouts (which take a while to layout). But no per-cell CSS (slow) and per-cell signal item bind/unbind (slow) and gtk_label_set_text (apparently also slow, adds up). I also plan to make it keep the scroll pos on reload (a bit broken in ColumnView).---sorry, should've titled this "i rewrote my rust app in zig and it became 5x faster 🚀"

The problem of slow janky web and electron apps on the desktop is widely discussed, and we have lower-level toolkits that we can use directly to make good performant apps (GTK, Qt, some of the 27 Microsoft toolkits, AppKit, then even lower-level stuff like ImGui, Win32).What about Android? I'm not very familiar with development there, but as a user it feels like many modern apps struggle with performance. And with RAM, considering they start unloading after switching twice on this 8 GB phone..

@a1ba nowadays the standard is Compose. Is that performant?

Well, after playing around with Zig (final version at [1]), my opinion is that while Zig is fun and nice for producing clean optimized assembly and custom allocation patterns (and will improve my Rust code going forward), having to keep track of all the cleanup does take up a disproportionate part of my brain, and I do frequently make memory mistakes.To conclude I wrote the same custom table widget in the Rust version, and it's ~as fast as the Zig one, as expected.[1] https://github.com/YaLTeR/tas-log-reader/tree/zig

So, this data table widget manages random scrolling at ~120 FPS. The main hotspots:- 49% pango layout| - 24% harfbuzz shaping (arguably useless here -- I only care about ASCII and digits)| - 7.2% line breaking (useless here)| - 7% itemization- 23% gtk_snapshot_append_layout| - 14.6% gsk_get_glyph_string_extents (lots of font map reloading here for some reason even tho it's the same few characters?)- 14% gsk_render_render| - 6.9% gsk_gpu_node_processor_process

(btw I completely forgot about Hotspot and it's such an amazing application. lets you do all kinds of filtering on the perf data)https://github.com/KDAB/hotspot

i borrowed a VR set from a friend so that i can finally complete HL:A (it's been a few years since i last played, so i'm restarting from scratch). and god, it's so good! so fun to play around with items and the environment. This is one of these experiences that really makes me feel and value the human creativity and soul that went into all of it

Do y'all see my replies to my long niri thread in the normal timeline? Or do you not unless I boost? Getting conflicting evidence here

I switched from Firefox to Telegram to paste a link, then switched back, and the current tab already unloaded. This Samsung S22+ has 8 GB of RAM. I am really at a loss, am I missing something about how computers operate?
