Docker on Android 🐋📱

Edit 🎉

All packages, except for Tini have been added to termux-root. To install them, simply pkg install root-repo && pkg install docker. This will install the whole docker suite, left only Tini to be compiled manually.

THIS GIST IS EXTREMELY OBSOLETE. DO NOT FOLLOW THESE INSTRUCTIONS. SERIOUSLY.

IF YOU IGNORE THE ABOVE WARNING, YOU AGREE IN ADVANCE THAT YOU DIDN'T GET THESE INSTRUCTIONS FROM ME, THAT I WARNED YOU, AND THAT I RESERVE THE RIGHT TO POINT AND LAUGH MOCKINGLY IF AND WHEN SOMETHING BREAKS HORRIBLY.

I'll do a write-up of current custom-kernel procedures over on Random Bytes ( https://randombytes.substack.com/ ) one day soon.

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2025-03-24: Commenting is disabled permanently. Previous comments are archived at web.archive.org. ]

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

What is Vulkan

Vulkan is a low-overhead, cross-platform 3D graphics and compute API.

Vulkan targets

Vulkan targets high-performance realtime 3D graphics applications such as games and interactive media across multiple platforms providing higher performance and lower CPU usage.
