Someone got Doom in an SQL database

2 October 2026 at 21:19

"Rendering Doom in a database is obviously a bad idea," Lukas Vogel writes in a lengthy blog post explaining how exactly he managed to render Doom using an SQL database.

OK, that's not entirely accurate. The SQLDoom project uses a small Python client to handle input and output, drive the game's timing, and display each frame to the screen. Behind that, a series of CedarDB tables tracks the game geometry and state, while about 1,300 lines of SQL queries spread across 89 common table expressions implement the game logic and generate 35 bitmap framebuffers per second.

In this, SQLDoom is a major improvement over Vogel's previous DoomQL project, which last year set out to build "a multiplayer Doom-like shooter entirely in SQL." Unfortunately, that effort ended up with raycasting-based, grayscale ASCII graphics that were more akin to the simplistic 90-degree-angled maps of Wolfenstein 3D. The newer SQLDoom, on the other hand, generates full-color 640x480 frames that look like they could have come from the original Doom executable.

Rocket Report: SpaceX completes launch triple-header; Rocket Lab nets big contract

2 October 2026 at 13:54

Welcome to Edition 9.13 of the Rocket Report!

This week, SpaceX celebrated the first orbital launch of its new Starship rocket. I'm not sure many people, at least those outside of SpaceX, expected it to take 14 flights of Starship before it technically reached low-Earth orbit, but Monday morning's launch finally added that to SpaceX's list of accomplishments with its new super-heavy rocket. Starship had gone 99 percent of the way to orbit before, only held back by safety concerns around the possibility of stranding the huge rocket in space.

What was most notable for SpaceX with this Starship flight was that it unlocked a massive growth potential for Starlink, with the first 26 of the network's new-generation Starlink V3 satellites successfully deployed Monday.
