Your "simulation" might not need state
The bouncing DVD logo is a fun and easy coding project. Watching Daniel Shiffman code it in p5.js is one of my earliest programming memories. However, the naive solution is far from optimal.

Parsing time stamps faster with SIMD instructions
In software, it is common to represent time as a time-stamp string. It is usually specified by a time format string. Some standards use the format %Y%m%d%H%M%S meaning that we print the year, the month, the day, the hours, the minutes and the seconds. The current time as I write this blog post would be … Continue…

C++23: Removing garbage collection support
If we go through the list of C++23 features, we can stumble upon the notion of garbage collection twice. Once among the language and once among the library features. Both entries refer to the same paper (P2186R2): garbage collection (GC in short) support is getting removed from C++. Just to make it clear, it’s not…

Reorient GitHub pull requests around changesets
I've had the experience of using GitHub as a maintainer for very large open source projects (1000+ contributors), as an engineer for very large closed source corporate projects, and everything smaller. Through those experiences up to today, GitHub pull requests is where I spend almost all of my time while on GitHub…

Optimizing Open Addressing
Your default hash table should be open-addressed, using Robin Hood linear probing with backward-shift deletion. When prioritizing deterministic performance over memory efficiency, two-way chaining is also a good choice.

Python: Just Write SQL
I have been writing a lot more Go this past year. For those not familiar, Go favours a non-ORM, non-query-builder approach to interacting with databases. This comes naturally due to the sql package : A common interface to be used alongside database drivers. It’s very common to see actual SQL in Go, even in large…

Local async executors and why they should be the default
Imagine you are new to Rust and you want to learn some async programming. Writing a chat server is a common way to start, scope is small enough to contain in a blog post, yet it is complex enough to learn most of what you'll need to build async servers in Rust. One DuckDuckGo query and we are off to the races…

The combined power of F# and C#
Where C# is the most dominant language in the .NET world, other languages are built on top of the Framework that deserves their respective place. F# is strong when it comes down to functional programming! In this blog post, we will leverage the power of F# and C# to showcase where both excel!

The anatomy of a Godot API call
UPDATE: This article has started an ongoing conversation with the Godot devs. They care about the issues raised, and would like to improve things. Significant improvements will almost certainly be made, although it’s still early days and it’s unclear what will change and by how much. I am encouraged by the response. I…

Filenames and pathnames in shell: How to do it correctly (2020)
This article explains how to correctly handle filenames in Bourne shells (the primary shell of Unix/Linux/POSIX systems), based on the issues discussed in 'Fixing Unix/Linux/Filenames'. Many programs fail to work properly on filenames that include spaces, begin with dash (-), include newlines, and so on, because…
