Building Principia for Windows XP

28 June 2026

Back in the day when Principia originally released for Windows in 2014, the game would run on versions as far back as Windows XP. Given that Principia 1.4 was released while Windows XP still had mainstream support, this of course made sense at the time, and there was no real reason not to support it given that the tooling and dependencies at the time were still compatible with it.

Fast forward to today with Principia as an open source project. While the Windows version should still run as far back as Windows 7, our usage of modern toolchains, dependencies and system libraries such as UCRT means that hard to truly guarantee far into the future as the ecosystem moves forward. However, this has always been something I wanted to change one day, bringing Principia back onto Windows XP and producing a fully open source build of the game that can run on it.

@guigui I was just checking up on SceneSat and saw they had gotten a new site redesign: scenesat.com The redesign itself doesn't seem all that bad until I went to the new About page of the site. All the text just feels off and very unlike how the […] [Original post on hachyderm.io]

/* Star layers are kept against the VIEWPORT via position:fixed pseudo-elements rather than
background-attachment:fixed on html/body (which used to carry
just the starfield here). That property is unreliable on iOS WebKit — Safari AND
Chrome-for-iOS alike, since Apple requires every iOS browser to use Safari's own engine —
where it commonly just behaves as background-attachment:scroll, so the starfield visibly
scrolled along with the page instead of staying put as a backdrop (reported 2026-08-31).
position:fixed is reliably supported there (this site already leans on it elsewhere: the
header, the footer player, the corner clock's old home before it moved into the status
bar). The oversized inset leaves a gutter for the tiny transforms, so no edge can enter
the viewport while either layer drifts.

The starfield itself: a seamless 2048x2048 tile generated by scripts/make-starfield.py
(see its header for why the tile is square, and why the asset is lossless WebP); `auto`
keeps it at native size, since scaling it would soften the stars and, worse, shrink the
repeat distance.

z-index MUST be negative, not 0 — this cost a real regression 2026-08-31, caught only
after shipping: per the CSS stacking spec, non-positioned in-flow content (#content,
site-footer — everything here is plain position:static) paints in an EARLIER phase than
ANY positioned element carrying a z-index of 0, even explicitly. So at z-index:0 this
pseudo-element painted ON TOP of the entire page, not behind it — invisible for years with
just the near-transparent gradient (16% opacity, fading to nothing), but the starfield
tile is opaque enough to visibly blank out every real content section once it joined this
layer. Negative z-index moves it into the phase that paints BEFORE non-positioned content,
restoring "backdrop behind everything" without needing position:relative on #content and
every other static content wrapper on the site. */

/* Theatre mode WITH a chat rail: widen the whole pane GROUP, not the frame on its own.

html.ss-theatre .video-frame above breaks the frame out with margin-left:50% + translateX —
inside this grid that centres it on its own TRACK rather than on the viewport, so it lands
half a track to the left and overlaps the rail. That is why theatre used to stack the two
panes; but a live chat pushed below a viewport-tall video is a chat nobody reads, which is the
same reason .watch-panes exists at all. So neutralise the frame's breakout here and break the
grid out instead: the frame simply fills a much wider track, and the chat keeps its place
beside it.

Width = what a 16:9 frame needs to fill the viewport height (the same
100vh − player − chrome term the frame's own rule uses), plus the rail and the gap, capped at
the viewport. The 48vw floor keeps the height term from collapsing the frame on short
viewports, where it goes negative — same guard, lower than the frame-alone rule's 60vw
because the rail is taking a slice of the width here.

Full-bleed via margin-left, NOT translateX: a transformed ancestor becomes the containing
block for its descendants, and the rail below is position:sticky. */

03 October 2026 | EU citizen
Anonymous (Sweden)

I am the sole volunteer maintainer of an open source physics-based sandbox game which contains an online community and user generated content in the form of levels featuring various mechanical and electronical contraptions made in the game. The EU Kids Act, as it currently stands, appears to make it effectively impossible to keep operating this project when costly effective age verification measures are needed. The money I receive in donations barely cover the current ongoing server costs as it currently stands, and my personal income as a university student to put into the project is very limited. We have no algorithmic feeds, lootboxes, microtransactions or similar addictive features, and we strive to offer a safe place for people of any age to play the game and explore electronics, logical circuits and programming through Lua scripting with active moderation in place and a strong privacy policy. Banning users under the age of 18 from this sounds absurd, but a more reasonable prospect than spending unpaid development time on implementing all features required for the different age groups below the age of 18. As an example for how some of the points in the proposal are counter-intuitive for us - the implementation of screentime limits would mean adding new always-on surveillance technology in the client running on the user's local device, regularly phoning back to the game servers to check how long the guardian has set the screentime limit to - and as the game is open source, I have no way of enforcing this compliance for a potential fork of the project. I understand that there may be similarly small online communities that do actually pose great harms to children, and a blanket exemption for small, non-commercial, or personally run platforms would create loopholes in the legislation as already mentioned in the proposal. But I still implore the Commission to clarify or explore amendments to the proposal to allow under-funded community projects like mine who want to do the right thing to keep being able to operate legally under EU jurisdiction.

Are we Imgui yet? Sooner than you'd think! I've been on an absolute roll ever since the last Principia release on Thursday implementing and fixing up Imgui dialogs for the game. I think me making this page tracking the progress with a coloured bar really helped […] [Original post on hachyderm.io]

Are we Imgui Yet?

Principia is currently in the process of having all dialogs in the game migrated from GTK to Dear Imgui. Due to the amount of dialogs used in the game, this is a long process and will gradually happen over time, until there are no GTK dialogs left in the game.

This page tracks the current progress of each dialog in the game.

Legend
(Red) Not implemented
(Orange) Dialog exists but is not finished
(Yellow) Fully implemented and included in latest nightly
(Green) Fully implemented and included in latest stable release

Current progress:
Green - 4 (6.8%)
Yellow - 32 (54.2%)
Orange - 5 (8.5%)
Red - 18 (30.5%)

Neither is recreating the entire 27 000 node linked list when removing a single node, when recreating it means doing I/O for each node. :neofox_woozy: I did not write this code originally. I fixed the whole _recreating the whole linked list_ by just removing […] [Original post on hachyderm.io]

Also apparently the Hetzner referral program is... over, ended last month but existing codes are still valid. Oh well, nobody used my code anyways.

Referral program ended

The referral program ended on 15 June 2026 and is no longer available.

If you previously participated in the program, your existing Hetzner Cloud promo codes remain valid until 31 December 2027 and can still be redeemed.

Replacing GTK dialogs with Imgui ones piecemeal was probably the best decision I've made. So satisfying getting to delete large chunks of old GTK dialog code as I make my way through the list of dialogs in the game, ui_gtk3.cc gradually shrinking until there will be nothing left.

Un-unused? so it's used, right?

Moving Principia off of GTK and to Dear Imgui for dialogs is something that has been worked on slowly throughout the years. Emphasis on slowly. My brilliant idea for how to go forward with it is to make the migration more gradual, because now after my recent […] [Original post on hachyderm.io]

Been doing some refactoring of the Dear Imgui UI code in Principia to split up the init and draw of Imgui stuff itself from the Principia-specific dialogs, such that I could have a build with both Imgui and GTK dialogs. The idea being that we can start using […] [Original post on hachyderm.io]

I usually upload the raw versions of Principia videos to an entry on archive.org for safekeeping, but I feel like I might need to find a better place to offload stuff...

It seems like someone deleted the entire /pub/ directory on kernel.org, hosting Linux kernel source tarballs and whatnot. Nothing is lost and the directory structure seems to be gradually reappearing, but all the tarballs for kernel sources hosted there are still 404 for now.

https://cdn.kernel.org/pub/linux/kernel/, normally a directory index over Linux kernel downloads, shows a 404 not found nginx error page.
