> You claimed "Ventoy adds repos". It does not. It is incapable of doing anything of the kind. It does not run on the installed system. It does not modify the boot media in any way. This is demonstrable and verifiable.
It literally adds an rdinit to the kernel boot line that hijacks the boot process and messes with it in a shell script. This is demonstrable and verifiable: https://github.com/ventoy/Ventoy/blob/master/IMG/cpio/ventoy...

Project mention: Zero-Copy Buffer Manipulation: Parsing Market Data at Memory Speed | dev.to | 2026-03-20
When a TCP packet lands, your OS writes it into a kernel buffer. libuv (makes Node not single lane), copies that packet from the kernel buffer to a Node buffer. The data event fires for one. So far, so good. Most code then does something like this:

Learn-Vim
Learning Vim and Vimscript doesn't have to be hard. This is the guide that you're looking for 📖
If you want to learn Vim, I highly recommend checking out Learn Vim (the Smart Way). It's a free, beginner-friendly guide that covers everything from the basics to advanced topics and is a great resource for both new and experienced users.

> There are frameworks and libraries that handle 100% of clipboard OS specifics
They're sufficient in many cases, but you'll still sometimes need the control of working with COM/etc. directly, and those libraries don't fully save you from platform-specific bugs (e.g: https://github.com/glfw/glfw/issues/2644).
> the app in question has no use for system clipboard in the first place
What do you expect to happen when you copy some text from an external editor into a text field?

For Debian-based images, swap apk add for apt-get install -y tini. There's also dumb-init, which is similar and slightly different in signal-forwarding behavior. Both are fine.

The lack of typedef can be independently verified by scanning the source code for the C compiler, specifically its keyword table, that’s part of Sixth Edition Unix (Unix V6) released in 1975 — no typedef.

ravynos
An open-source OS project that aims to provide source and binary compatibility with macOS® and a similar user experience.

https://fishshell.com/ https://xon.sh/ https://www.nushell.sh/ https://elv.sh/
You're replying to someone that says POSIX shells are holding people back, not that the terminal is a bad idea, there are many alternative shells which offer benefits over POSIX shells. fish-shell has everything you want from an interactive shell included, xonsh is a mix Python shell, nushell and elvish are adding types and other things to shell.
The VT protocols that all shells have to confirm with are pretty dated and I'd love to throw them off the roof for something less stateful and with multiple font sizes but there's no arguing that text based interfaces are good.
