The first warehouse robot I found impressive looked nothing like a robot from a movie. It was a low platform moving shelves. No face. No arms. No conversation. It rolled under a storage rack, lifted it slightly and carried the entire rack toward a worker. That was it. The machine was useful because it did…

The first good mixed-reality headset demo I tried was impressive for about twenty minutes. Windows floated in the room. A 3D object sat on a table that did not actually contain it. Video looked enormous. Hand tracking felt slightly magical. Then I wanted to answer a normal email. The headset became a computer attached to…

I used to hesitate before saving a card in an app. The mental picture was simple: the company would store my card number in a database, and one day that database might appear in a breach notification. Sometimes that is still close to reality. Increasingly, though, payment systems try not to pass the real card…

A team I worked with once had twelve monitoring dashboards open during an outage. CPU graphs. Database latency. Application errors. Network traffic. Cloud metrics. Customer experience. Queue depth. Another dashboard whose owner nobody could identify. The room looked very informed. Nobody knew what was wrong. That was the moment I stopped believing that more observability…

I once built a tiny script that checked a service every minute. “Any new orders?” No. One minute later: “Any new orders?” No. Again. The script worked. It was also ridiculous. Most of the day, nothing happened. The software kept asking anyway, creating unnecessary requests, logs and opportunities to fail. Then I learned to use…

A browser extension once saved me enough time that I recommended it to everyone. It cleaned up a repetitive web task, added one useful button and mostly stayed out of the way. Months later, the extension changed owners. Its privacy policy changed too. The new version wanted broader access than before. I removed it. The…

I used to scan QR codes without thinking. Menu on a table? Scan. Parking meter? Scan. Poster at an airport? Scan. A little square stuck to the side of a payment machine? Probably fine. Then I saw somebody scan a QR code that had been placed over the original sticker on a parking sign. It…

Most people buy a laptop without knowing which instruction set architecture runs underneath it. That is reasonable. You care whether the machine is fast, quiet, affordable and able to run your software. The processor’s internal language can stay invisible. Still, one chip architecture is becoming difficult for the technology industry to ignore. RISC-V is an…

A familiar travel-day problem goes like this. You open a website on your phone, it asks for a password you haven’t typed in months, and suddenly you are standing near an airport charging point trying to remember whether you added an exclamation mark or a year to the end of it. Then comes the reset…

A lot of people delay learning software because they think the “engineering part” begins after they learn Python, JavaScript, or whatever language YouTube is recommending this month. I think that’s backwards. Code is a tool. The more useful shift happens earlier, when you stop treating problems as solid walls and start treating them as systems…
