The source code for the classic PSX launch title wipEout was leaked in 2022. A few month ago I finally sat down to take a look at it. The result is a (nearly) complete rewrite that compiles to Windows, Linux, macOS and WASM. Thanks to WASM and WebGL you can play wipEout right in your browser! I'm not the only one who embarked on a path to restore the game. To my knowledge, there are two other effo
Here is a dumb question that you probably never asked yourself: What is the minimal amount of bytes we need to store in a .NET executable to have the CLR print the string"Hello, World!" to the standard output?

Nowadays, the industry would very much like you to ditch your paper ticket in favour of a fancy mobile barcode one (or an ITSO smartcard2); not only do the
Anybody remember these weird rectangles from the photo above? They were all over tech news websites almost a decade ago. They were supposed to usher in the new age of photography. Some of you might have them tucked away in some drawer as a reminder of wasted money. The product promised so much, yet what it delivered in reality was oh so disappointing.
