rustdesk
An open-source remote desktop application designed for self-hosting, as an alternative to TeamViewer.
Project mention: A web-based RDP client built with Go WebAssembly and grdp | news.ycombinator.com | 2026-04-25With hp shutting down anyware / teradici / pcoip there are quite a few people looking for alternatives that support high resolution multi monitor with 60fps high bit depth playback and things like wacom tablet support and all three OS. Parsec and DCV are out there on the spend money side. I'm excited about the open source efforts. Things like rustdesk,kyber, and teraguchi. The community needs an open source high performance option.

Windows Terminal
The new Windows Terminal and the original Windows console host, all in the same place!
>I doubt that people think it's the engineering teams that are the problem
Did you forget Microsoft engineering response to Casey Muratori "Extremely slow performance when processing virtual terminal sequences"?
"I believe what you’re doing is describing something that might be considered an entire doctoral research project in performant terminal emulation as “extremely simple” somewhat combatively."
https://github.com/microsoft/terminal/issues/10362#issuecomm...
followed by Casey producing evidence for his 'extremely simple' claim in couple of days.

> Like… has anyone done a Jepsen-like stress test on rsyslogd and shared the results? I’ve half-assedly looked before and not been able to find anything.
I've not used rsyslogd specifically, but I don't see how you'd have any issues with the log volume you described.

> 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...

Ligatures are a renderer issue, so using alacritty as a lib wouldn't have this issue (it does demonstrate their hardline stance). Another example that would translate is how long it took them to support disambiguation of key combinations: https://github.com/alacritty/alacritty/issues/6378 (2019-2023). Of course, the maintainers are free to do whatever they want with the project - but such things do make alacritty-as-a-lib an exceptionally bad choice for situations where you want things to just work.

tldr is perfect when man pages are too detailed and you only need the common examples.
-
mkcert
A simple zero-config tool to make locally trusted development certificates with any names you'd like.
On install it generates an ECDSA P-256 root CA at ~/.mkdev/ca/ (private key written 0o400, owner-read only) and installs it into the OS-native trust store. The trust-store integration — Keychain via security on macOS, the CA-bundle dirs plus update-ca-* on Linux, the ROOT store via crypt32.dll on Windows — is adapted from mkcert (BSD-3, credited in LICENSE-MKCERT). That layer is the genuinely OS-specific part and reusing it saved a lot of pain.

ImHex
🔍 A Hex Editor for Reverse Engineers, Programmers and people who value their retinas when working at 3 AM.
ImHex (https://imhex.werwolv.net/) is also a really nice Hex editor with tons of plugins (patterns, file support, etc.) and even an embedded language for adding more patterns easily
-
it reminds me of https://github.com/dockur/windows with its compose-style YAML over QEMU/KVM. The difference i'm seeing is scope: dockur ships curated OS images (Windows/macOS), while holos looks more like a generic single-host VM runner. Is that a fair read? also curious any plans to support running unattended processes for OS installs?

Win11Debloat
A simple, lightweight PowerShell script that allows you to remove pre-installed apps, disable telemetry, as well as perform various other changes to declutter and customize your Windows experience. Win11Debloat works for both Windows 10 and Windows 11.
Project mention: Microsoft bans the word "Microslop" on its Discord, then locks the server | news.ycombinator.com | 2026-03-02Win11debloat solves 99% of annoyances with Windows 11 in <5 minutes. I’ve used in as the first step on every Win 11 install for years. It’s mostly just a bunch of Powershell commands disabling/configuring features.
https://github.com/Raphire/Win11Debloat
Nothing has ever reverted after an update for me, so it’s a one-and-done thing. Ironically, afterwards Windows 11 has fewer noticeable ads than my MacBook which still continually pushes Apple services/shows/etc in settings/push notifications.
The only setting that I’ve ever seen sneakily disabled in recent years is the Edge default search engine but that's out-of-scope for Win11debloat.
