Semantic Versioning – fearlessly breaking things

Semantic versioning (or semver) is a very basic concept that stirs a bit of controversy on the internet. A quick google for “semantic versioning problems” brings back a number of essays about all the shortcomings.

I googled around a bunch and couldn’t find any association with the way I’m using it, so I’m just gonna keep using it until somebody is […]

Computers like words too!

This isn’t about a micromaterial per se, but more about the data used to create micromaterials. I was reading an excellent blog post about word lists, and wondered how many of them were accessible in formats other than excel spreadsheets. I soon found out that a lot of them were actually in pdfs (notoriously difficult to […]
