This is the 3rd post in the My journey with Home Assistant focus series. I’m the happy owner of a couple of Philips Hue connected lights for a some years. Some of them are colored, some of them regular. In addition, I bought a sensor to go along with the light I installed in my toilets: it turns on automatically when…
On June 26, 1826, John James Audubon sat aboard the cotton schooner Delos off of Florida’s Gulf coast, en route from New Orleans to Liverpool, where he was hoping to find a publisher for his extensive portfolio of paintings of American birds.[1] On this particular day, the winds were still, leaving Audubon’s boat to…

A bunch of malicious extensions in Chrome Web Store have hidden affiliate fraud functionality, collect users’ browsing profiles, or both. These extensions appear to be connected to the Karma shopping assistant, developed by Karma Shopping Ltd. which is not a small company.
Zngur (/zængɑr/) is a C++/Rust interop tool. It tries to expose arbitrary Rust types, methods, and functions while preserving their semantics and ergonomics as much as possible. Using Zngur, you can use arbitrary Rust crates in your C++ code as easily as using them in normal Rust code, and you can write idiomatic…
“Summing ASCII Encoded Integers on Haswell at the Speed of memcpy” turned out more popular than I expected, which inspired me to take on another challenge on HighLoad: Counting uint8s . I’m currently only #13 on the leaderboard, ~7% behind #1, but I have already learned some interesting things. In this post I’ll…
I did not expect this! [...] we are announcing today the general availability of a foundational open data set, Foursquare Open Source Places ("FSQ OS Places"). This base layer of …

I am Dan, full stack software engineer.
Why do I do this to myself? I have no idea. Anyway, let's learn how to eat disk space.
About a year ago I blogged about games that use curl. In that post I listed a bunch of well-known titles I knew use curl and there was a list of 136 additional games giving credit to curl. Kind of amazing that over one hundred games decided to use curl! At the time, lots of … Continue reading Inside 22,734 Steam games…
Detailed description of an algorithm and a comparison between different languages.
“Software design is preparation for change; change of behavior” Tidy First? is a new book by Kent Beck. It is a short little book, only about 100 pages (and lots of white space on them)…
Lessons from the plagiarists of the steppe
The boolean satisfiability problem (“SAT” for short) is arguably the most famous NP-complete problem in theoretical computer science. According to Wikipedia, it is “the problem of determining if there exists an interpretation that satisfies a given Boolean formula ”; or, in simpler terms, if there is at least one…
Visualizations and techniques for different maze generation algorithms.
Database queries are a pretty surprisingly powerful tool that can solve seemingly intractable problems.

The computer built to last 50 years par Ploum - Lionel Dricot.
How much Vitamin D should I take? This is still the looming question, and it’s time to address it. First, though, imagine that someone in a public forum online asked me, “How much metoprolol (a…
Even relatively new C programmers have no trouble reading simple C declarations such as
(Enjoy the blog? Please consider donating – there’s a PayPal button at the top right of the site!) Over the past several years of spending far too much time and money on stationery, I’ve learned a thing or two — about mistakes I make over and over, about what I like and why, and what […]
Every now and then, I stumble onto some algorithm or idea that’s so clever and such a perfect solution to a problem that I feel like I got smarter or gained a new superpower just by learning it. Heaps were one, just about the only thing I got out of my truncated CS education. I recently stumbled onto another: Pratt or…
