notpublicon Show HN: Open-source browser for AI agents

Thanks! I assume you are referring to this https://github.com/obra/superpowers

I use it as well (a customized version suited for my worflow). It is indeed the GOAT.

From the commit history, it looks like you are using Claude for some of the development. Would love to hear how you are using Claude to go through such a massive code base.

btw, impressive project.

notpublicon Thanks a lot, AI: Hard drives are sold out for the year, says WD

Bestbuy with local pickup. They price match Amazon. B&H Photo is another option.

notpublicon We rendered and embedded one million CAD files

Thanks! In my search for a good STL for the following, your app gave me the closest model so far!

https://m.media-amazon.com/images/I/41hGjsBlrKL._AC_SL1000_....

I tried Google/Claude etc. But none worked. As per Claude, the technical name for that is Pillow Block Bearing/Shaft Coupling Block/Flange Mount Bracket. Funny thing is, your app didn't return any good result when I search with any of those terms.

After reading your blog post, I searched for "block with 2 holes". And lo and behold, it returned ABC-00162357!

Couple of suggestions: 1) Have a permanent link for each model 2) Show related models when a model is clicked 3) and lastly, show models based on an image

edit: Search for "mounting block" returned ABC-00180735 which is exactly what I was looking for. Thank you so much for making this!

notpublicon Trinity large: An open 400B sparse MoE model

Yep. You be right. Looks like they increased it earlier this month. Bummer!

notpublicon Trinity large: An open 400B sparse MoE model

Talking about RAM prices, you can still get a framework Max+ 395 with 128GB RAM for ~$2,459 USD. They have not increased the price for it yet.

notpublicon IPv6 is not insecure because it lacks a NAT

Is it fair to say IPV6 with ULA (Unique Local Addresses) is best of both worlds?

notpublicon Claude Advanced Tool Use

Try adding a session hook that triggers on startup|resume|clear|compact to remind Claude about your custom skills.

notpublicon Claude Advanced Tool Use

Another thing that helps is adding a session hook that triggers on startup|resume|clear|compact to remind Claude about your custom skills. Keeps things consistent, especially when you're using it for a long time without clearing context

notpublicon Claude Advanced Tool Use

Instead of including all these instructions in CLAUDE.md, have you considered using custom Skills? I’ve implemented something similar, and Skills works really well. The only downside is that it may consume more tokens.

notpublicon Free interactive tool that shows you how PCIe lanes work on motherboards

Check out the following for AM5 motherboards. It helped me a lot when I was in the market. Seems to be well maintained still:

https://docs.google.com/spreadsheets/d/1NQHkDEcgDPm34Mns3C93...

I ended up getting ASRock X870E Taichi Lite. The main reason to get it was because it had 2 CPU x8 slots which are spaced perfectly for an Nvidia NVLink. And, they are Gen5 PCIe.

notpublicon Anthropic’s paper smells like bullshit

What is the proper way to disclose evidence for this class of hacking?

notpublicon Anthropic’s paper smells like bullshit

If you know what to look for, the report actually has quite a few details on how they did it. In fact, when the report came out, all it did was confirm my suspicions.

notpublicon Anthropic’s paper smells like bullshit

"A report was recently published by an AI-research company called Anthropic. They are the ones who notably created Claude, an AI-assistant for coding. Personally, I don’t use it but that is besides the point."

Not sure if the author has tried any other AI-assistants for coding. People who haven't tried coding AI assistant underestimates its capabilities (though unfortunately, those who use them overestimate what they can do too). Having used Claude for some time, I find the report's assertions quite plausible.

notpublicon The lazy Git UI you didn't know you need

Indeed! I just found out about tmux display-popup recently.

  # ~/.tmux.conf 
  bind-key C-g display-popup -E -d "#{pane_current_path}" -xC -yC -w 80% -h 75% "lazygit"

Then, in tmux:

  ctrl-b ctrl-g will open a popup window with lazygit

notpublicon Coordinating the Superbowl's visual fidelity with Elixir

My experience has been just the opposite. We have moved all our apps to Elixir now. It has one of the best developer experience to work with. Especially for concurrent programming.

I suspect OP is using an umbrella app as a shared library or something. That is the only explanation I can think of that can cause the issue with compilation order.

About documentation, not quite sure what the OP is talking about. Elixir and Erlang have really good documentation.

Anyway, to truly appreciate Elixir (and for that matter Erlang), one needs to understand OTP and the philosophy behind it. It is not just a language but a framework to build concurrent application.

notpublicon The best way to use text embeddings portably is with Parquet and Polars

please do explain why

notpublicon Embedding Python in Elixir, it's fine

> ..but things like macros in Ecto....

Well, The whole language itself is built on macros. The following series of articles certainly helped me stop worrying and love the macros..

https://www.theerlangelist.com/article/macros_1

Some interesting insights from the article: "Elixir itself is heavily powered by macros. Many constructs, such as defmodule, def, if, unless, and even defmacro[1] are actually macros...."

notpublicon OCRing Music from YouTube with Common Lisp

Do try it. We use it for text search in one of our apps and works remarkably well. Basically to find which chunks contain the given text. Since the text can span multiple chunks, a simple string search will not work.

Instead of doing a diff, curious if Normalized compression distance (NCD)[1] will yield a better result. It is very simple algorithm:

to compare two images, i1 and i2

  l1  = length(gzip(i1))
  l2  = length(gzip(i2))
  l12 = length(gzip(concatenate(i1, i2))

  ncd = (l12 - min(l1, l2))/max(l1, l2)

Here is a nice article where I found out about this long ago.

https://yieldthought.com/post/95722882055/machine-learning-t...

From the article:

"Basically it states that the degree of similarity between two objects can be approximated by the degree to which you can better compress them by concatenating them into one object rather than compressing them individually."
