LLMs can't do probability
I've seen a couple of recent posts where the writer mentioned asking LLMs to do something with a certain probability or a certain percentage of the time. There is a particular example that stuck in my mind which I've since lost the link to (If you're the author, please get in touch so I can link through to you): The…

Don't Roll Your Own
This is going to be a rant about modern web design practices. But before I get to that, let me begin with a familiar principle from the world of cryptography. Among software developers, and especially among those who work on security-sensitive systems, there is a well-known maxim: Don't roll your own crypto. This does…

Julia's multiple dispatch explained with Pokemons
T hese days, I find myself evangelizing for Julia quite a bit. It’s a good language, especially for scientific computing, but I believe its focus on performance also makes it a good general language as well.

Building a MongoDB Clone in Postgres
I had a crazy thought. Don't all good ideas start with that phrase? Well, this one was suitably crazy: why not build my own version of MongoDB right on top of Postgres? It sounds a little far-fetched, but in all honesty it's pretty simple.
