Restoring and MIDI-Fying a Baby Grand Piano
As much as I love digital instruments, synthesizers and other electronic gear I also really love the look and feel of instruments made from wood, brass, steel and felt. There is objectively no difference between the best digitally sampled pianos but for some reason it doesn’t quite feel as much alive as an actual…

Zsh and Fish’s simple but clever trick for highlighting missing linefeeds

Fast 2D Rendering on GPU
Previously on my quest for fast rendering of 2D vector graphics on GPU, I have posted a piet-gpu update and a deeper exploration into a sort-middle architecture. These intermediate results showed promise, but fell short of my vision for truly high performance 2D GPU rendering.

Ansible Alternatives in Python
My VPS will soon expire, so I've decided to try to automate its deployment. After spending evening by studying Ansible alternatives, I've decided to use pyinfra, and I am quite happy with it.

Async Python is not faster
Async Python is slower than "sync" Python under a realistic benchmark. A bigger worry is that async frameworks go a bit wobbly under load.

Have you ever had to draw an architecture diagram and found the repetitive clicking and dragging tedious? Did you have to do modifications to that diagram and found it complicated? Graphviz is an open source graph visualization software that allows us to decribe a diagram using code, and have it automatically drawn…

Writing a full-text search engine using Bloom filters (2013)
A few minutes ago I came across a Hacker News post that detailed a method of adding search to your static site. As you probably know, adding search to a static site is a bit tricky, because you can’t just send the query to a server and have the server process it and return the results. If you want full-text search…

Pain Points of Haskell
I would like to preface this article by saying that Haskell is great. I have been using it as my go-to for native applications for several years now. Everything that follows is a product of my love and affection for the language, and a desire to see it succeed. And none of this is intended to disparage the efforts of…

Faster than radix sort: Kirkpatrick-Reisch sorting
Radix sort sorts n w-bit integers by splitting them up into chunks of logn\log nlogn bits each, and sorting each chunk in linear time. Thus it achieves O(nw/logn)O(nw/\log n)O(nw/logn) time.
