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.

Project mention: Best Open Source Monitoring Tools in 2026: 7 Self-Hosted Options Compared | dev.to | 2026-06-13
Netdata is a real-time infrastructure monitoring agent that collects metrics at per-second granularity with near-zero configuration. Install the agent on a server, and within seconds you have 2,000+ metrics being collected — CPU, memory, disk I/O, network, processes, containers, and hundreds of application-specific collectors. The level of instant visibility is unmatched.

> 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...

This was Fig's smartest move. Every other approach at the time either forced you onto a brand-new terminal emulator (Warp, Tabby) or left you stuck with the weak completion of the day. Fig chose to piggyback instead — it supported macOS Terminal, iTerm2, Tabby, Hyper, Kitty, WezTerm, Alacritty, and even the embedded terminals in VS Code, the JetBrains IDEs, and Android Studio. You changed nothing. You installed an app.

tldr is perfect when man pages are too detailed and you only need the common examples.

Project mention: Show HN: Write.md, a free, open-source, themeable Markdown editor for macOS | news.ycombinator.com | 2026-08-11
Recently adopted https://github.com/marktext/marktext as I wanted the editable preview that Obsidian offers, but for all .md, not just items in my vault. I dig it so far. And it does offer printing of the render.

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.

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: YTAudioBar VS spotube - a user suggested alternative | libhunt.com/r/ytaudiobar | 2026-08-07
Spotube streams free via YouTube instead of requiring Spotify Premium — closest match to YTAudioBar's approach, though it's mobile+desktop cross-platform where YTAudioBar is desktop-only.
