One of my main inspiration these last few years, especially for my consultancy, is Nikhil Suresh, aka Ludic. Last week, I spoke to him to ask him about his experience setting up Hermit Tech, consulting practices and pitfalls, and funny stor…
Or, Deep Work is Illegible Or, Everything Worth Learning You'll Have to Teach Yourself I remember quite clearly how I learned Git. Spring quarter of my second year of undergrad, I took Data Ethics, which was a required course in the Data Sc…
All of which are basically the same blog post for slightly different audiences. In light of a conversation I had last week, I figured it was worthwhile to write up the main pitch for Rust in scientific programming, specifically for Python-R…
A few days ago I read Micah Kepe's jsongrep is faster than {jq, jmespath, jsonpath-rust, jql}. There, he promoted an approach to high-performance JSON querying using DFAs generated by a regex-inspired JSON query language, with seriously imp…
After several months working part-time on optimizing McFACTS, I think we're rapidly approaching saturation: one by one, we've cut the tall poppies down, cooled the hot paths, until the largest contributors to the runtime are either bookkeep…
For the latest batch of optimizations speeding up/replacing AstroPy unit operations in McFACTS (expect my next blog post titled The Agony and the Ecstasy of AstroPy Units), I've wound up just extracting the string representation of the unit…
I was reading David Nicholson's Domain-driven software design is a good idea, still a couple days ago, and it struck a few thoughts loose in my head. By way of summary, though you should read the original, Nicholson introduces the concept o…
Yesterday, I shared a rather lengthy post about various ways to optimize NumPy array operations with lower-level solutions. One of the findings was that a zipped Rust array could be faster than NumPy, but it depended on several factors: Of
I've been contributing on and off to the McFACTS simulation project for a few months now, and am currently in the process of testing and merging some pretty substantial optimizations to the core 'business logic' of the simulation, which mai…
You are reading this because you, or someone close to you, is learning Python for scientific programming. This post intends to be a launchpad, providing introductions to the main concepts involved, some guidance on the Python in general, on…
A few days ago, I read Victor Skvortsov's I Switched From VSCode to Zed on Lobsters. It was a neat, short article, not too applicable to me since I don't use Zed very often (I just fall back to it periodically when I can't get nvim LSPs wor…
