Principia and the Open Letter from Keep Android Open
Keep Android Open is a grassroots campaign originally launched in October 2025 by Marc Prud’hommeaux as a response to Google’s Android developer verification announcement last year, which requires all Android developers to pay a fee and verify their identity with Google even if they do not distribute apps through the Google Play Store. I have previously written on my blog about the Google Play developer policy update that Google originally announced in July of 2023, and how my Google Play developer account was suspended in February last year as a result of my refusal to comply. So when Google announced this new policy change for distributing outside of Google Play too, I was rather furious by the fact that Google is further exercising control over the Android ecosystem. Safe to say, I wholly supported the Keep Android Open campaign when it was originally launched, and got very intrigued to throw my hat into the ring as the Principia project maintainer.

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.

![/**
* The chat in a window of its own (docs/chat.md, "Pop-out window").
*
* On the site, [data-chat-popout] buttons — the floating panel's launcher row and the /chat page —
* take the chat out of the page:
* - "window" opens /chat/popout as a browser popup that the chat fills, at the size and place it
* last had;
* - "top" floats the same page above every other app, in an iframe inside a Document
* Picture-in-Picture window (Chrome, Edge). It closes with the tab that opened it: the
* browser's rule, not ours.
* The buttons are rendered hidden and only what this browser can do is revealed; nothing on a
* touch-only device, where a popup is just another tab.
*
* The pop-out page (body[data-chat-popout-window]) and every tab talk over the "ss-chat-window"
* BroadcastChannel. The pop-out says "open" when it loads and when pinged, "closed" when it goes;
* while one is open, the floating panel shows a placeholder instead of a second live copy. A link
* to the rest of the site clicked in the pop-out is handed to the tab that opened it ("navigate"),
* which follows it as a boosted navigation so the music never stops; with that tab gone, the link
* opens in a new one. Only one pop-out at a time: opening one asks any other to "close". "Put
* back" in the pop-out ("dock") and "Bring it back here" in the panel return the chat to the page.
