SimpleDB: A Basic RDBMS Built from Scratch
My databases class at UCLA wasn’t very challenging so I never truly understood the internals of databases. This always bothered me so I vowed to build a simple database from scratch to learn the fundamentals. MIT's Database Systems course has their students implement a simple database from scratch and it provided me…

Scripting with Elixir
I was a Python developer for some time and one great joy of Python is that you have an expressive language that you can use for your serious apps as well as for your hacky little one-off script or bespoke pieces of automation. By expressive I mean that typing very little can give you a lot of progress towards your…

Deep Learning 101
Deep learning has become something of a buzzword in recent years with the explosion of 'big data', 'data science', and their derivatives mentioned in the media. Justifiably, deep learning approaches have recently blown other state-of-the-art machine learning methods out of the water for standardized problems such as…

Prospero: A new coding harness for a more civilized age
I’ve been fascinated with local LLMs for a couple of years now. The better open weight models, including some that inference on regular, higher-end consumer hardware at tolerable speeds, are now reliable enough to handle simpler programming tasks. This requires a coding harness, but so far this year I’ve been…
