Good lord, have mercy on my soul for that slur of corporate speech I just wrote. How would you like yet another workspace vignette? During this event, I had the opportunity to have a conversation with some junior colleagues as well as with one high level executive. https://yeikoff.xyz/blog/26-12-2025-ai-enabled-management/ Fri, 26 Dec 2025 10:10:33 +0100 https://yeikoff.xyz/blog/26-12-2025-ai-enabled-management/ A new data point from the workbench of technical work In 1887, Nietzsche noted (Late Notebooks 10[11]) how the current education system is a key enabler for the leveling of man: transforming kids into good office clerks, soldiers or factory workers. A process through which the uniqueness of the individual is sanded towards non-existence. By 2025 this is a widely hold point of view. From this particular fact, Nietzsche extrapolated (Late Notebooks 10[17]) the "total economic management of the Earth. https://yeikoff.xyz/blog/11-02-2025-do-i-want-coders-to-code/ Sun, 02 Nov 2025 12:14:57 +0100 https://yeikoff.xyz/blog/11-02-2025-do-i-want-coders-to-code/ At the beginning of the year I explored the willingness to code of coders. As the year has gone by, I think it's time to review my thoughts on it. At the end of that post, I ended up scratching my head: Why don't coders want to code? Here I will add some new data points and update my model of the world. And at the current point in time, what I am really wondering is "Do I want these people to code? https://yeikoff.xyz/blog/18-05-2025-scalasql-duckdb/ Sun, 18 May 2025 10:34:48 +0200 https://yeikoff.xyz/blog/18-05-2025-scalasql-duckdb/ Hell yeah! Now the question is: should we? While it's possible to use ScalaSQL on DuckDB, current limitations of ScalaSQL make some bit's of data analytics tasks less than optimal. What's this about? DuckDB DuckDB is the latest rage in the analytical database space. This space seems to be weirdly dominated by big data tools and products. The weird bit is when you find yourself using these products to handle small data. https://yeikoff.xyz/blog/24-04-2025-coders-willing-to-code/ Thu, 24 Apr 2025 22:18:47 +0200 https://yeikoff.xyz/blog/24-04-2025-coders-willing-to-code/ Three workplace vignettes The new cloud vendor is worse because you have to code This week I ran into a junior colleague. He had switched projects. The one he is currently at uses a different cloud vendor than the project we were together. I asked him which cloud vendor he liked more. His answer: "I like the old one, it has a no code solution." Meanwhile, I had spent the whole morning click opsing through his no-codes, trying to figure out where a table was written into a database, wishing for grep. https://yeikoff.xyz/blog/10-10-2024-single-purpose-compute/ Thu, 10 Oct 2024 22:40:10 +0200 https://yeikoff.xyz/blog/10-10-2024-single-purpose-compute/ For the past two years, most of my work has been tied to these Platforms as a Software Substitute. I work on the data-sphere, so you might know the usual suspects: The one called like a process in your brain, the one that, by it's name, you could build a wall with or the one named after the crystallized water elements. No free publicity on these pages. At the end of the day, what they provide is a managed Spark service and an interface where you can easily run your code from. https://yeikoff.xyz/blog/09-02-2024-guix-fennel/ Fri, 09 Feb 2024 08:47:20 +0100 https://yeikoff.xyz/blog/09-02-2024-guix-fennel/ For the past two weekends I've been trying Guix out. Which means: I AM NO GUIX EXPERT. Everything stated here about Guix has a non-zero chance of being incorrect. Here I will gather my takeaways and conclusions about the system, as well as provide a starting point for Lua and Fennel developers that want to use Guix as their package and dependency manager. NOTICE: This post will only cover . https://yeikoff.xyz/blog/01-12-2023-juniors-scared/ Fri, 01 Dec 2023 16:09:07 +0100 https://yeikoff.xyz/blog/01-12-2023-juniors-scared/ I've been working with these two juniors lately. Smart and proactive, the kind that is really a pleasure to work with. Every time I meet with them, they are very thoughful, ask great questions and when they're stuck, they've already tried a whole bunch of things and bring a solid understanding of the issue at hand. Let's call them Jo and Sa. Last week I had to buy myself some time to push forward a given project. https://yeikoff.xyz/blog/27-10-2020-project-fails/ Fri, 27 Oct 2023 16:43:34 +0200 https://yeikoff.xyz/blog/27-10-2020-project-fails/ Introduction Some months ago, I begun my first ever technical leadership. I've done some mentoring and lead small teams over the last years. But this time I took over a ten people team. First, the lack of focus of the team looked iffy to me. About 6 months later, I am officially the Unofficial Psychologist for the team and have started regular group sessions with some members to let steam out. https://yeikoff.xyz/blog/29-09-dislike-python/ Fri, 29 Sep 2023 16:25:11 +0200 https://yeikoff.xyz/blog/29-09-dislike-python/ Earlier this week I was reviewing some Python code with a junior colleague, and thought: "Python can be pretty nice." This piece of code was in "production." I mean, while it was up and running on our dev environment, other people were relying on it. It was a single file, with a utility class and a main function. Less than 90 LoC. Today, I was harshly reminded why I dislike Python: It's deployment story is between poor and dangerous. https://yeikoff.xyz/blog/19-09-2023-scala-3-spark/ Tue, 19 Sep 2023 23:09:46 +0200 https://yeikoff.xyz/blog/19-09-2023-scala-3-spark/ Today I had the chance to try out Spark on Scala 3. The conclusion: Quite underwhelming. Introduction: Scala 3 is great. I've been using Scala 3 to write my dayjob scripts lately. While I have to admit that I was skeptic at first (particularly because significant whitespace has given me enough trouble with Python), I've been pleasantly surprised. Mostly because I haven't managed to make significant whitespace work with my Emacs setup.
