Buckaroo - the data table viewer for jupyter.

I recently integrated Lazy Polars and running analytics in background processes so I can reliably provide a fast table viewing experience on dataframes that would normally exhaust memory of the jupyter kernel. Analytics are run column by column and results are written to cache, if a column fits into memory individually, summary stats for the entire dataframe can be computed.

Here's a demo video of scrolling through 19M rows, and running background summary stats.

I’m building a netsuite competitor (having spent a lot of my career on accounting and erp implementations.)

The trick (one trick) is to allow LLMs to provide an audit/accounting/compliance playbook, along with customizations, based on the user describing their business model.

I've been a long time Windows user (20+ years) who heavily uses WSL 2 as my dev environment with tmux / Neovim but I'm switching to native Linux before the end of this year.

I tried once 7 years ago but ran into major audio issues that were a deal breaker but I'm hoping the Linux kernel has improved. I have the same hardware as before.

My dotfiles have been public for many years and can 1 shot a new or existing system in a few minutes with a bunch of command line tools on Debian, Ubuntu, Arch (with or without WSL 2) and macOS. It has an install script and theme switching for a long time which I've used to set up a a few systems (personal desktop, laptop and work laptop).

I've been casually tweaking a laptop running Arch with niri. I'm preparing a bunch of things in my https://github.com/nickjj/dotfiles to prepare for that push which will work on Arch Linux and be opt-in to install and configure a GUI and assorted tools.

I’m finishing up a language identification model that runs on cpu, 70k texts/s single thread, 13mb model artifact and 148 supported languages (though only ~100 have good accuracy).

This is a model trained as static embeddings from the gemma 3 token embeddings.

HALUD YOUR HORSES is a small containerized development workflow designed to reduce exposure to supply-chain attacks in the JavaScript and Node.js ecosystem. Every project runs inside an isolated container with its own node_modules volume. Nothing from npm executes directly on the host machine. The tools are simple shell scripts that create, enter, and fork project-specific development images.

Working on a TUI tool which demonstrates the behaviour of X86 SIMD instructions. This is all done in Go assembly, and is probably most valuable for Go programmers.

The problem for me was trying to read and understand the implementation of a swiss map implementation. The SIMD instructions were challenging to understand and the documentation felt difficult to read. I thought that if I had an interactive tool where I could set the inputs to a SIMD instruction and then read the outputs, understanding the instructions would be much easier.

This turned out to be true.

Building this tool for all AVX/AVX2 instructions turned out to be a larger task than I had expected. Naively I just went off a Wikipedia page on AXV and assumed it had listed all the instructions (this was a bad assumption).

I am nearly there. Looking forward to completing this project so I can actually use it to do some fun stuff processing text and maybe even get back to that swiss map implementation.

(This is also my first attempt at a TUI app)
