🌘 使用 Nix 自定義交叉編譯器：為 Risc OS 打造現代開發環境
➤ 跨越時空的編譯橋樑：從現代 Mac 到復古 Risc OS 的 Nix 實踐
✤ https://www.hobson.space/posts/nixcross/
這篇文章記錄了作者如何克服 Nix 生態系統中文件不足的挑戰，成功為復古作業系統 Risc OS 建構一套自定義的交叉編譯工具鏈。儘管作者已擁有針對 Risc OS 修改過的舊版 GCC 4.7.4，但在現代 Arm Mac 環境下直接編譯近乎不可能。透過 Nix 的 Flake 與強大的隔離機制，作者深入解析了 Nix 內部對 `buildPlatform`、`hostPlatform` 與 `targetPlatform` 的定義邏輯。他揭示瞭如何利用 `wrapCCWith` 封裝編譯器，並透過覆寫 `stdenv` 的巧妙技巧，讓 Nix 能自動處理工具前綴（如 `arm-unknown-riscos-gcc`），最終打造出一個如同原生 `pkgsCross` 般流暢的開

As questions about the previous post on #RISC_OS today's and tomorrow start flowing, I posted a new article with some answers to some of those. Please remember this is an open discussion, so if I have made errors please send me the corrections, thank you!

What Happens to RISC OS Applications if We Introduce Preemptive Multitasking?

In this article we discuss and analyse what can happen to traditional RISC OS software if a preemptive scheduler is introduced, as discussed in a previous post., “RISC OS applications rely on cooperative multitasking. If the operating system becomes preemptive, do all applications need to be rewritten?”, This seems to be a common and certainly…

RISC OS Today and Tomorrow: What Would Really Benefit the Platform

Author: Paolo Fabio Zaino., RISC OS is a unique operating system with a long and important history. It is relatively fast, elegant, and responsive, and people who use it enjoy it precisely because it feels different from mainstream systems. At the same time, RISC OS has been adapted to run on increasingly modern hardware, and…

This is #RiscOS night for sure!

2 more icons, not original work.

For Tahi, a somewhat chatty card game, a picture of Yugi from Yu-Gi-Oh.

For Angband, He Man's Sword of Power, from the ancient comic book.

Both trimmed down to 32x32.

IIRC I got both images from wikipedia.

Speaking of RISC OS games, it bugs me that "Microdrive" is a golf game and not something about Sinclair's tape storage... 🙁

I started a game of the updated RISC OS version, it looks pretty good.

New port of a RISC OS game to steam:

2018 update for current RISC OS machines:

Edit: I should note, RISC OS Exodus has screen mode pickiness and doesn't like anymode. The version from the JASPP site just crashes on my Pi2. The version they have via !packman works fine for me. 🤗

A retro Acorn RiscOS gem returns with Exodus: The Colonization of Space now on Steam

OK I have struggled with GNOME like elements in file chooser dialogues in XFCE for some time now and am considering a non-GTK desktop.

In XFCE, MATE and LXDE I can configure the title bar buttons in windows such that the close button is on the left and the minimise/maximise are on the right. See the attached image.

This is similar to the RISC OS layout and stops me accidentally closing windows.

Is this layout possible with the KDE/LXQt/Trinity desktops?
