Ask HN: What's the Best Open Source Tool You've Discovered Recently?

Best thing I've found recently is nushell[0], paired with jc [1] it's pretty much the best shell I've ever used.

What’s better about the nushell? I tried it a couple of years ago but didn’t enjoy using it — probably because I primarily use bash and nushell seems quite different from it.

Would appreciate if you could share some examples from your workflow!

I have a feeling you'll not appreciate my answer considering your current workflow.

I don't mind bash and the various cli programs I used to use for the tasks I was doing at the cli. However I was forced years ago to learn powershell. Now syntax aside I was able to use powershells native functionality to do things I'd have to call other programs for, read and process CSV, JSON, XML, etc. Nushell is like powershell but a much better syntax and I prefer the data model and love the output.

My main workflows consist of exploring data, cleaning it, and outputting what I need. Nushell has this covered.

Serious LLM vibes from the docs. Many paragraphs are repeated and pages amd pages of filler words like telling what you're going to learn over and over.

I actually like the docs, never really noticed an llm vibe... I most just search and look at the examples though.

Open WebUI[1] for a ChatGPT type experience locally hosted. Very impressive set of features and development velocity - so much so Qwen team using it now rather than building their own [2]

I really liked bropages, but it is defunct

I think tldr is similar though

For me it was the open source e-ink display TRMNL[2] which I learned about via ATP and Snazzy labs[1].

Now that I have an actually useful 3d printer, I really have gotten into FreeCad. Hopefully in a few more months I'll grok it well enough to gork/rewrite the gear generator tool kit. The rack generator, for example has no notion of where the pitch line is. This makes proper designs with mating gears a matter of trial and error.
