Beyond the machine

I’m just back from reading the transcript of Beyond the Machine, a thoughtful and insightful talk by Frank Chimero. I’m trying to figure out how to use generative AI as a designer without feeling like shit. I am fascinated with what it can do, impressed and repulsed by what it makes, and distrustful of its owners. I am deeply ambivalent about it all. The believers demand devotion, the critics demand abstinence, and to see AI as just another technology is to be a heretic twice over. Today, I’d like to try to open things up a bit. ...

Are we Trek yet?

This guide is intended to be a comprehensive look at the tech that Star Trek suggested to drive humanity forward ad astra per aspera. The emphasis is on innovations that don’t violate physics according to present consensus understanding. Go ahead and explore boldly. Are We Trek Yet? – A guide for how close we are to Star Trek technology is a funny, revealing, and well-executed idea. It is somewhat comforting that at the time of this writing, eight of all the Star Trek technologies are readily available, and thirty-one are in progress. It only tracks Star Trek technology, though. ...

What .NET 10 garbage collection changes really mean for developers

“For decades, garbage collection in .NET was a background concern. It was mostly invisible to the everyday developer and was regarded as ‘automatic’ unless (or until) something slowed down the application. However, .NET 10 changes this perspective by making garbage collection (GC) a key component of application performance.” What .NET 10 GC Changes Mean for Developers is a good in-depth article that explores the revolutionary garbage collection improvements in .NET 10, which deliver 2- 3x performance gains through seven key enhancements: escape analysis for stack allocation, DATAS enabled by default, flexible region sizing, delegate optimizations, intelligent write barrier elimination, enhanced devirtualization, and refined heap controls for containers. ...

Ur-Fascism

Prompted by an old post by Bob Schwartz (2017), I revisited and reread Ur-Fascism, the essay Umberto Eco wrote in 1995 for the New York Review of Books. What are the features of Fascism? We need to know, so we can recognize them and point them out as they emerge, as they always tend to do, time and time again, as our societies struggle to evolve. Sounds like heavy reading material, but it isn’t. I mean, look at the incipit: ...

Finally some good news for us old farts! Cognitive ability (probably) peaks between 50 and 60.

Why exercise is a miracle drug

Last year, Ashley and a large team of scientists conducted an elaborate experiment on the effects of exercise on the mammalian body. In one test, Ashley put rats on tiny treadmills, worked them out for weeks, and cut into them to investigate how their organs and vessels responded to the workout compared to a control group of more sedentary rodents.1 The results were spectacular. Exercise transformed just about every tissue and molecular system that Ashley and his co-authors studied—not just the muscles and heart, but also the liver, adrenal glands, fat, and immune system ...

Cognitive load is what matters

Sometimes we feel confusion going through the code. Confusion costs time and money. Confusion is caused by high cognitive load. It’s not some fancy abstract concept, but rather a fundamental human constraint. It’s not imagined, it’s there and we can feel it. Since we spend far more time reading and understanding code than writing it, we should constantly ask ourselves whether we are embedding excessive cognitive load into our code. ...

Why arent people going to conferences anymore?

Brent Ozar’s article below resonates with my post-COVID experience as a conference speaker. From big national and international conferences to local meetups like the one I run, attendance has been dwindling following the hiatus. Of all the proposed reasons, I believe “people switched how they’re learning” is crucial; just think about YouTube, LLMs, and the plethora of free and paid online courses. Why Aren’t People Going to Local and Regional In-Person Events Anymore? ...

Python: The Documentary

This is the story of the world’s most beloved programming language: Python. What began as a side project in Amsterdam during the 1990s became the software powering artificial intelligence, data science and some of the world’s biggest companies. But Python’s future wasn’t certain; at one point it almost disappeared. Python: The Documentary

The first-line treatment for ADHD

The first-line treatment for ADHD is stimulants. Everything else in this post works best as a complement to, rather than as an alternative to, stimulant medication. In fact most of the strategies described here, I was only able to execute after starting stimulants. For me, chemistry is the critical node in the tech tree: the todo list, the pomodoro timers, etc., all of that was unlocked by the medication Notes on Managing ADHD ...
