Biggest image in the smallest space
What’s the biggest pixel size of a PNG image in the smallest number of bytes? I wanted to try to create an image that could be downloaded but whose pixel buffer would be too big to store in the RAM of a PC. Here is a PNG image of 6,132,534 bytes (5.8 MB) and 225,000 × 225,000 pixels (50.625 gigapixels), which, if…

A Tour of the Lisps
2023 seems to have been the year where I "made the rounds" of a number of major Lisps. There were several elements that lead to this. Firstly must have been my exposure to Elixir in 2022, which introduced me to the idea of debugging live systems and "staying in your program". Secondly must have been my chief complaint…

Rust as a gateway drug to Haskell
For work-related reasons, I had to recently get up to speed on programming in Haskell. Before that, I had very little actual experience with the language, clocking probably at less than a thousand lines of working code over a couple of years. Nothing impressive either: some wrapper script here, some experimental…

Translating math into code with examples in Java, Racket, Haskell, Python (2011)
These structures are so universal that most research papers in the theory of computation, programming languages and formal methods present concepts in terms of discrete mathematics rather than code.

PDF to Text, a challenging problem
The search engine has recently gained the ability to index the PDF file format. The change will deploy over a few months. Extracting text information from PDFs is a significantly bigger challenge than it might seem. The crux of the problem is that the file format isn’t a text format at all, but a graphical format. It…
