The phrase “digital twin” makes me think of a glowing 3D model floating above a conference table. That is probably the fault of technology marketing. The practical version is usually less cinematic. A company takes data from a real machine, building, vehicle or process and creates a digital representation that helps people understand what is…

The first time I used a serious photo editor inside a browser, I had the same reaction I get when hotel Wi-Fi works unusually well. Suspicion. The application felt too capable for a web page. Large files opened. Tools responded quickly. The whole thing behaved more like installed software than a tab I would accidentally…

A friend sent me a video of a famous person saying something ridiculous. “Real?” he asked. Five years ago, I would have watched the face carefully, looked for strange blinking and declared myself an amateur forensic expert. Now I do something much less satisfying. I check where the video came from. Deepfakes and AI-generated media…

“Zero trust” sounds hostile. The phrase makes me picture an office where everyone is suspicious of everyone else and a security guard follows employees to the coffee machine. The actual idea is less dramatic. For years, company networks often worked on a simple assumption: people and devices inside the corporate network were safer than things…

A note-taking app once refused to show me my own notes because the train had entered a dead zone. The notes were on the device. I had opened them earlier that morning. Still, the app wanted to talk to a server before behaving normally. I stared at the loading spinner with unnecessary anger. That moment…

A developer once described a memory bug to me using a sentence I still remember. “The program is reading something that no longer belongs to it.” That sounded less like software engineering and more like a boundary dispute. Languages such as C and C++ give programmers enormous control over how memory is used. That control…

I stopped wearing a smartwatch to bed because it annoyed me. Not in a dramatic way. It was simply another screen on my wrist, glowing occasionally, bumping against the pillow and reminding me that even sleep had become something I was apparently supposed to optimise. A friend suggested a smart ring. My first reaction was…

My old laptop once needed a new battery. The battery itself was not the problem. Finding out whether I could replace it without turning the laptop into an expensive puzzle was the problem. I watched repair videos, checked parts websites and discovered that one version of the model used different adhesive from another. Eventually the…

I once searched for an old address online and found a people-search site listing places I had lived, possible relatives and an age range. Some details were wrong. Enough were right to make me uncomfortable. I had never created an account on the site. I had never uploaded a profile. Nobody had asked me to…

A colleague once deleted a folder from his laptop and said, “It’s fine, everything is in the cloud.” It was. The cloud very efficiently deleted the folder from his other devices too. That day taught a lesson that technology companies do not always explain clearly enough: synchronisation and backup are different jobs. Cloud sync is…
