I have always felt lucky to have learned C and Magic: The Gathering at the same time (1994). I am not sure if the C helped my MTG playing more or vice versa.
Selecto, an elixir SQL query library that works with or without Ecto. Also SelectoComponents which gives you a web interface to build queries.
It is based on 20+ years of experience maintaining a similar system in Perl.
It's on Hex.pm already, looking for people to test and comment!
As Codex would say:
Selecto is an open-source SQL query builder for Elixir that helps you generate complex queries from clean, domain-based configs. It supports advanced joins, CTEs, subqueries, and analytics-friendly patterns, with companion packages for LiveView interfaces (selecto_components) and code generation (selecto_mix). If your app is data-heavy, Selecto gives you SQL-level power without brittle hand-written query strings.
When I first got my CPAP it was not helping at all. I complained and got a new sleep study WHILE using the CPAP that showed it was not helping. They gave a prescription for an oxygen concentrator to attach to the CPAP. That cut my events-per-hour to 1/10th what it was. When I travel, I take the CPAP but not the OX, and I can really tell the difference. I live in Colorado, and I sleep better with CPAP+OX than at sea level with just CPAP.
Also around that time that me and my friends learned what 'Extended Area' calling was- we all thought that if it was not long distance then it must be free! I remember us solemnly concluding that we would have to 'hack' the phone company. All of us also very special.
