Excellent overview with code. Can't say for sure that it is a true/accurate explanation or just a clever oversimplified analogy.

Once Heroku got rid of their free tier, we all wanted alternatives. Doku is one of them. It lets you create your very own Heroku service on top of a cheap Digitial Ocean partition.

Interesting GEM. Twirp is an RPC format and protocol from Twitch. Looks useful.

Remember this gem. It looks really useful for collecting stats from Rails based sites.

Some fancy sql technique to create masses of fake data efficiently. Note: no Ruby or Python involved!

Just heard about CTE (Common Table Expressions). They are a feature of SQL. Not sure whether all SQLs or just Postgres. A way to refactor a complicated SQL statement into substagements.

A very useful documenation of various pre-boot config files for Rasberry Pi

We’re all doing it now, right? Using LLMs for all kinds of things? Well here are some useful rules of thumb. By the way, as far as employing a team of assistants, take a look at Poe.com. It’s a single front end to all (almost all) the LLMs out there. And in fact it bakes in the question of what would the other LLMs say to the same prompt.

A brave new world!

This article lays out many of the things that worry and bother me about the way we teach, assess and grade.

Useful comparison between Hanami and rmRails. I would have expected a Hanami bias. But even in this, I think Rails ends up on top!

I agree with the high level argument. The open source situation does need a solution. But in general, we need to find ways to pay software developers more for the work they put into writing software. Wait! What do I mean? We have trained the world to expect to pay $0 for software that took huge numbers of person months to create. $4.90 is expensive!
