A surprising enum size optimization in the Rust compiler Enums are one of the most popular features in Rust. An enum is type whose value is one of a specified set of variants. /// Foo is either a 32-bit integer or character. enum Foo { Int(u32), Char(char), } Values of type Foo are either integers (e.g. the variant Foo::Int(3) with a payload of 3 ) or characters (e.g. the variant Foo::Char('A') with a payload of 'A' ). If you think of structs as being the and combination of their fields, enum

The next part of the Advent of Code puzzle involves interpreting instructions called do() and don't() which turn on and off the contributions of mul instructions to the sum. As we parse, we now need to keep track of one bit of state. This is a nightmare for regexes to deal with, because they recognise regular languages, and regular languages are literally stateless languages.2 There’s more nuance, of course, but as a first approximation. Technically regular languages are those that can be recogn

How “deleting multiplayer from the engine” can save memory Although the title of this article might suggest otherwise, I don’t dislike Unreal’s multiplayer features. As someone who has worked on two different multiplayer games in Unreal, I enjoy Unreal’s seamless multiplayer integration. It’s built deep into the engine instead of being moved to an optional plugin like so many other features. You can test any project in multiplayer mode without writing a single line of code. Of course, it will n

Measuring acceleration structures Hardware accelerated raytracing, as supported by DirectX 12 and Vulkan, relies on an abstract data structure that stores scene geometry, known as “acceleration structure” and often referred to as “BVH” or “BLAS”. Unlike geometry representation for rasterization, rendering engines can not customize the data layout; unlike texture formats, the layout is not standardized across vendors. It may seem like a trivial matter - surely, by 2025 all implementations are c

The internet is massive. But does it have … actual mass? Big server farms and miles of fiber-optic cables do, of course, but we don’t mean the infrastructure of the internet. We mean the internet itself. The information. The data. The cybernetics. And because storing and moving stuff through cyberspace requires energy—which, per Einstein, has mass—it should, in theory, be possible to calculate the internet’s weight. Way back in the adolescent days of the web, in 2006, a Harvard physicist named

Compound document file format Compound File Binary Format (CFBF), also called Compound File, Compound Document format,[1] or Composite Document File V2[2] (CDF), is a compound document file format for storing numerous files and streams within a single file on a disk. CFBF is developed by Microsoft and is an implementation of Microsoft COM Structured Storage.[3][4][5] The file format is used for storing storage objects and stream objects in a hierarchical structure within a single file.[6] Micr

This week-end project started by browsing the open-data repository of Paris’ public transport network, which contains various APIs to query real-time departures, current disruptions, etc. The data reuse section caught my eye, as it features external projects that use this open data. In particular, the RATP status website provides a really nice interface to visualize historical disruptions on metro, RER/train and tramway lines. A usual day of disruptions on ratpstatus.fr.
