The term “psychological safety” is often misleading. When managers hear safety, many dismiss it as a soft style that implies complacency. Meanwhile, psychology implies too much mumbo jumbo. High-profile figures like Elon Musk advocating for a “hardcore” style perpetuate this misconception. But this is a fundamental…
tl;dr: I made ViHN to read Hacker News without having to move my hands away from the keyboard. It’s freely available on Firefox and Chrome. This is about yet another Hacker News extension. But other people with my obsession for killing the mouse might enjoy it. Most of the content of this article is just […]
WARNING: the following contains a whole lot of pedantry about proving theorems at a level of detail such that you could likely convince a co...
A look ahead at some ongoing projects in PostgreSQL in 2024 and beyond
I do a lot of electronics projects in my spare time, and I tend to try to make reusable parts to save myself effort in the future. Because I have to order ingredients in certain quantities, I often wind up with more than I need for my project.
With separate plastic, metal, paper, and glass recycling, composting, and pick up of all the rest, knowing which days to put out which bins ...
The best websites are home-cooked meals. Andrew’s Selkouutiset Archive was birthed after I realized there was no obvious way to fetch the previous articles of the “Easy Finnish” daily news broadcast. This annoyed me as a student of the language. “Here we have a stream”, I thought, “of high-quality, human-written…
Before I got into reverse engineering, executables always seemed like black magic to me. I always wondered how stuff worked under the hood, and how binary code is represented inside .exe files, and how hard it is to modify this ‘compiled code’ without access to the original source code.
Let me set the right expectations first. This bug I found is actually not that complicated, it's very straightforward once you see what's going on. But I still think the process it took me to uncover this bug could be interesting. It's also kind of interesting that a simple bug stayed undiscovered for so long. I will…
Understanding the real world is not always easy. A Python simulation can help. And let's find ways of making it efficient, too.
Folding antennas into different shapes to create near infinite radiation patterns.
Don't panic! Here's how to tactfully answer salary expectations questions without costing yourself a ton of money
Explore the intriguing history of Eliza, a pioneering chatbot, and learn how to implement a basic version in Go, unraveling the roots of conversational AI.
The chief hurdle in constructing a Death Star is not the energy, materials, or even knowledge needed. It’s the long time needed. A society can change their mind mid-way over centuries, and simply move on. The galaxy is likely strewn … Continue reading →
You receive a message. Now either you will be victim or not. Your knowledge, attention and moral compass will decide where you will end up.
“As we look to sleep and neuroscience for answers we can study flies specifically the Drosophila melanogaster we highlight in our research.”
This article is about the Y combinator, a fixed-point combinator that provides a way of using recursion in scenarios and programming languages where symbols are not available. The concept of the Y combinator itself is closely related to lambda calculus (λ-calculus) and functional programming languages. More…
Photography is arguably my oldest hobby. I’ve loved taking photos for as long as I can remember. I reflected on my first encounter with digital photography in 2003 in a recent post, but I’m old enough…
Yesterday I discovered a deluge of recent fake customer reviews for a number of top paid apps in the United States Mac App Store. (Each country has its own version of the App Store with separate reviews.) I've now checked the reviews for all of the current top 40 paid apps in the Mac App Store, and 8 of those apps…
Ah. Orange Spain has had their /12 (and likely others) broken by (what appears to be) someone breaking into their RIPE account and making RPKI ROA's to somewher...
In a previous post, I’ve shown how to use the rayon framework in Rust to automatically parallelize a loop computation across multiple CPU cores.Disappointingly, my benchmarks showed that this only provided a 2x speedup for my workload, on a computer with 8 CPU threads.Worse, the total “user” and “system” times…

When doing systems programming we often need to wait for something to happen. Common examples might be waiting for some data to come through a socket or waiting on a lock. We also often want to wait on any of several conditions to become true. A web server might be handling many sockets at once, waiting for any number…
Trackmania: the world's most competitive racing game. In this post, we begin our journey towards training a neural network to superhuman performance, by chronicling the history of previous attempts.
I recently learned Spotify provides downloads for users’ streaming history. For me, this is over 10 years worth of data, so at the very least it seemed like a good nostalgia trip. This post covers some of my analysis of my personal export, and hopefully is a good starting place if you’re interested in exploring your…
I recently found that MAME supports running the SGI Indy while looking for ways to test some modifications I was making to the mips code in 9front. After a fair bit of elbow grease cinap and I (but mostly cinap) were able to get the old 9front indy kernel booting and running within mame. I thought I might as well…
