I think LLMs are accelerating us toward a Dune-like universe, where humans come before AI.

Wow. I saved the link for emergencies. And I sent it to all my team. It is like a diff tool but to advance the schema.

I don't think MariaDB ColumnStore has any kind of advantage. It is just an append-only storage format with some columnar concepts.

This ColumnStore is very simple and just do table scans sequentially on every query. It doesn't support indexes and unique constraints. It is almost an append-only serialization file format, but with some columnar concepts.

I am hosting user data from the database. It is very easy with this stack: - PostgreSQL with PostGIS - Django with MVT-tiles plugin - MapLibre

I do. The pros are hosting own data and have total control over stack and cloud hosting. The cons are having to code your own stack and do cloud management. I use PostGis to storage and serve vector tiles. And I use a simple backend with AWS S3 to store and serve raster data (GeoTiff COG).

It was nice in 2015-2017 when I got a free Windows 10 license for my Dell Ubuntu Linux Notebook (much cheaper to buy in Brazil). Back then most of the games only was on Windows. Nowadays I have a Lenovo with Windows 10/11 license but I do not used Windows since 2024.

So it was not released yet. What is keeping Valve from release it? Apple is "giving a hand" now.

You can always use pyenv to install any Python on any mainstream Linux. I only use pyenv Python to develop on any laptop or any server. My dev laptop is still Ubuntu 22.04 and I have any Python from 2.7 to 3.14 .

Nice to see "collateral benefits" from RNA vaccines. Remembers me of Viagra collateral effect in angina treatment.
