Project mention: Show HN: A backend agnostic Ruby framework for building reactive desktop apps | news.ycombinator.com | 2025-05-09
Very cool project, and well thought with the choice of Raylib or SDL2. But since Raylib can compile to Android (https://github.com/raysan5/raylib/blob/master/examples/Makef...), do you think it could be difficult to add Android as a target platform ?

Project mention: Show HN: WindTerm – Introducing a better Tmux experience | news.ycombinator.com | 2025-03-11

I guess https://github.com/jart/cosmopolitan might just be the WebAssembly for the command line then.

Project mention: Show HN: Lume – OS Lightweight CLI/API for macOS/Linux VMs on Apple Silicon | news.ycombinator.com | 2025-02-02
You can, with ish (https://ish.app). It is a bit slow though and doesn't support the newest releases. (Well and by default it runs Alpine instead of Debian)

Today is a lazy Sunday, and I did what nobody should do on a Sunday: Spend time trying to replace something that already works. This time, my victim was rofi.

ecapture
Capturing SSL/TLS plaintext without a CA certificate using eBPF. Supported on Linux/Android kernels for amd64/arm64.

Project mention: Show HN: Most users won't report bugs unless you make it stupidly easy | news.ycombinator.com | 2025-06-09
Is this a reference to https://github.com/systemd/systemd/issues/5644#issuecomment-... ?

As I discussed in my previous devlog, I decided to go with glfw for handling the window creation for this engine. It is a library I used a ton before. And while I do fancy replacing it later, it will suffice for now.

AppImageKit
Package desktop applications as AppImages that run on common Linux-based operating systems, such as RHEL, CentOS, openSUSE, SLED, Ubuntu, Fedora, debian and derivatives. Join #AppImage on irc.libera.chat
Project mention: Show HN: Finic – open-source platform for building browser automations | news.ycombinator.com | 2024-09-17Like again if you are not sure, what open source means, this is open source: https://appimage.org/
Hope it is abundantly clear with this example. Docker tried it's best to do the whole open source but business first and it led to disastrous results.
At best this will make your company suffer and second guess itself and at worst this is moral fraud.
Talk to your group partner about this and explain to them as well.

Project mention: Show HN: ProgressLine – Track commands progress in a compact one-line format | news.ycombinator.com | 2024-07-18
A related tool, except for monitoring I/O, is Progress [1].
Imagine that behind the scenes it does something like lsof every second (-m flag) and tracks the progress of any file open by the specified process(es) (-c or -a flags). Works great for copying and downloading, doesn't work for rewriting in-place.
This reminds me that I wanted to modify my GNU Screen hardstatus to call it.

htop came to mind.
