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. ...

The Marmarole Mountains: a three-day solo hike in the Dolomites

The Marmarole mountain group is an island of quiet, where, especially at the end of the season, it’s easy not to meet anyone for entire days. Nature is harsh and wild; steep, apparently inaccessible ridges separate the slopes and basins. It follows that the elevation gains are significant and many obligatory passages are often technical, exposed and equipped with steel cables (via ferrata). Water is scarce everywhere, especially on the north face, which also lacks refuges at altitude. Up there, the support structures are spartan bivouacs, isolated and challenging to reach. The solitude up there is almost total, but frequent encounters with high-altitude wildlife compensate for it. It’s easy to spot chamois, ibex, marmots, and eagles. ...

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: ...

The view from the exposed ledge below the summit

The Monte Mauro loop

On Sunday afternoon, I suddenly decided to take my motorcycle, ride to the foothills, leave the bike there, and hike the Monte Mauro loop, including the climb to the summit. The Monte Mauro loop is a classic route in the Vena del Gesso area. Wooded areas alternate with exposed stretches below the summit of Monte Mauro, where you literally walk on chalk outcrops. The trail is well marked, but you have to pay attention to the path because there are often alternatives (also marked) that can confuse you. It is an enjoyable short tour. ...

Age and cognitive ability

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 ...

Empty nest

A few weeks ago, we accompanied Anna to Amsterdam, where she will study at the University. She is our youngest daughter. Marco left home years ago to study in France, where he graduated, and now lives in Brussels, and Giulia is in her third year of medical school, also living in another town. After twenty-plus years, the nest is empty. It’s a strange feeling wandering around the house knowing that none of the kids are around. Despite feeling nostalgic, Serena and I are doing well. We’re getting used to this new life as a seasoned couple. ...

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. ...
