Five years of data engineering
Five years ago I made the switch from Oracle database administration to data engineering. It has been quite a ride. I made a video about this to celebrate.

First experiments with the OAK-D Lite
Last week my OAK-D Lite from Luxonis arrived. I can imagine you’ve never heard from it. Basically it is a camera that can do all kinds of AI tasks on the device itself. I got mine via Kickstarter. And where I say camera, I actually mean it has multiple cameras. That’s how it can see depth for example.
It can do much more. Load an algorithm, point it at the street next to your house and it starts detecting cars, cyclists and pedestrians. Load the human posture algorithm and it starts showing your posture. Or gestures, sign language, face recognition or COVID-19 mask detection.

What a year 2021 has been
So at the end of 2021 I found myself in the waiting room of an emergency dentist. An infection above my front teeth became unbearable. Fortunately antibiotics makes my live much better now. Let that event not colour my view on 2021. For me 2021 was a great year, despite the pandemic, lockdowns and those damned curfews. Luckily 2021 eventually also had vaccinations. And what a difference a year makes. Last year I was frantically Read more

Weekendlinks 2021-47: bike crashes, Tetris and Airflow foundations
It’s weekend and it’s raining. Time to play some computer games. Bikrash In meatspace I try to avoid crashing with my bike. But in this free game they are rampant. And you can actually win by causing them, by kicking other racers. Also watch out for the road spanning, enormous potholes. https://hisashimaru.itch.io/bikrash AI does Tetris. Fast! This is fun to watch. The Stackrabbit algorithm plays Tetris so fast, at a certain point it Read more

Weekendlinks 2021-46 brrrr, space juggling and salt crystals
I have to say, I’m a fan of long summer nights where I can ride my bike for hours after work in short sleeves. This is not that time. The sun goes under at 16:45 now. So if I do decide I want to ride my bike after work, I need some good bike lights to see where I am. But hey, at least it’s not as cold as in Yakutia. (Please summer, come back Read more

Gaining insights on my workout data with Apache Superset
For a few years I’ve been gathering data on my workouts. In Excel. It’s not exactly state of the art data architecture, but it was fine for a while. But data alone doesn’t do much. I wanted some questions answered. Lately I’ve been hearing a lot about Apache Superset. (Well, I’ve been hearing lately about lots of products actually. It’s hard to choose one product to spend a lot of time on.) Apache Superset is Read more

Weekendlinks 2021-41: Rickrolling, carbon capture, Shatner’s flight
Last weekend I was too busy either cycling or celebrating that I rode 10,000 kms this year. Nevertheless, here are this weekend’s links. Rickrolling your high school by hacking the IPTV system This student managed to gain access to his high school’s IPTV system. And he carefully prepared a rickrolling prank. https://whitehoodhacker.net/posts/2021-10-04-the-big-rick This carbon capture method might actually work Let’s face it: if we’re dependent on all polical leaders to do their part Read more

Question I’m pondering I was listening to Lex Fridman’s podcast where he interviews Daniel Kahneman. You might have heard about Kahneman: he wrote the influential book “Thinking Fast and Slow”. It is about the two modes of thinking our brain: System 1 (fast, instinctive and emotional) and System 2 (slower, more deliberative, and more logical). At one point in the interview Fridman and Kahneman discuss happiness. Kahneman tells he gave up on happiness research. Read more

I’m back for a wonderful cycling holiday in the Vercors and Drôme regions of France. And this is what it looked like: But enough of that. Let’s have some weekend links.

And it’s not just a more watery potato. There were Read more
