This is a site that maps the references on Gary Overacre's 1980s UNIX Magic poster to short write-ups with sources. I posted an earlier version about a year ago [1]. Since then I rewrote some of the annotations, added deep-linking to individual markers and a frame/sidebar view...

While speccing out this spreadsheet tool, I realized that I never had to think about the keybindings. It all just came naturally from Vim. Normal/insert/visual modes, hjkl navigation, dd/yy/p, :w, :q. The usual muscle memory works. It supports CSV/TSV import and export, and a...

The standard GPU utilization metric reported by nvidia-smi, nvtop, Weights & Biases, Amazon CloudWatch, Google Cloud Monitoring, and Azure Monitor is highly misleading. It reports the fraction of time that any kernel is running on the GPU, which means a GPU can report 100% uti...

I built a SQL analyst agent based on a simple idea: generating SQL is not the same as doing analysis. Most text-to-SQL tools stop at producing a query. But real analysis is iterative. You explore the schema, run queries, adjust, and refine. This project tries to model that loo...

On a trip with my friend, he introduced me to Kalshi and Polymarket and was shocked at how degenerate it was being able to bet on literally anything. So naturally I built an app ironically where we could do the same thing (with fake money) on group outings! Managed to get a pr...

Greetings HN! I've forked the excellent work done by [vlaci/git-agecrypt]( https://github.com/vlaci/git-agecrypt ), looks like the original project has not been maintained for a while, so I decided to pick it up, update all the dependencies and add some thorough testing. I lik...
