There is a plethora of data and research available that outlines *exactly* how companies can build a hiring process for software engineers that's truly predictive of their future, on-the-job performance. Yet, the tech industry at large has all but ignored these practices opting instead for antiquated hiring processes…
“If you want more effective programmers, you will discover that they should not waste their time debugging, they should not introduce the bugs to start with.” —Edsger Dijkstra, Turing Award Lecture (1972)
Learn Robotics and ROS 2 Have you been looking for a good place to start your robotics and ROS 2 learning journey? Look no further! We are proud to announce that together with the University of Eastern Finland, we have open-sourced the robotics part from our “Robotics & XR” master’s-level course. You can find the […]

When you have to traverse some sort of a nested data structure (say, a binary tree), one approach is to create a stack that remembers where in the tree you are. Another, much more elegant approach, is to write the function recursively. A recursive function employs the machine stack used to implicitly implement…
Another rogue patcher.
So how hard could it be. As input we have something like Fri, 17 Jan 2025 06:07:07 in UTC, and we’d like to turn this into 1737094027, the notional (but not actual) number of seconds that have passed since 1970-01-01 00:00:00 UTC. Trying to figure this out led me to discover many ‘surprise features’ and otherwise…
History of Perl releases since version 5.6, each with a summary of added or changed features.
When I use classes, when I don't, what I do instead, and why
Explore the Qt Blog for the latest insights on e.g. Qt Creator, your go-to source for cross-platform development tips and updates.
The trick to understanding awk in all its terse glory is to understand its defaults. Most solutions you see in the wild are a clever symphony of awk defaults stacked on top of each other. In this post, I break down one of the most popular one-liners which should hopefully make future awk-ing pretty straight forward.
Rust is my favorite programming language. I've been writing Rust for about 6 years, from college to professionally, and I'm vocal about how helpful the compi...
How to design resilient architectural patterns that last the test of time
Intro I recently worked through a problem from a theory of computation textbook that asked me to prove a property of a language using finite automata. The informal proof is a simple constructive proof where you build an automaton and show that it recognizes the language. This is kind of similar to program…
Before the AI era, I wrote pretty long commit descriptions (or commit bodies) for major changes. It took me about five to ten minutes to draft and reread them to make sure I didn’t miss anything important. I did that for several reasons.
A bootcamp can teach you the syntax of a language in six weeks. The part that takes a decade is everything else: where the seams go, where the data flows, which decisions you are stuck with for the life of the codebase. This is a senior developer's argument for what learners should actually be looking for, after…
In this post, I talk about my favorite C/C++ pattern involving macros.
It was seven years ago today when everybody was getting excited about Microsoft’s bombastic announcement of Hailstorm, promising that “Hailstorm makes the technology in your life work t…
While I was looking the other way, Python got advanced static types! Here’s matrix multiplication, describing the input shapes and its output shape:
A deep dive into HTML whitespace collapsing: How it works, why it sucks, how it should work, and how to deal with it.

Curious why D3.js code looks long and complicated? I quickly explain why D3 is verbose, how it gives developers control, and what makes it powerful for data visualisation.
After the Graz, Austria February 2025 WG14 Meeting, I am now confident in the final status of the defer TS, and it is now time.
