When mobile data works but Wi-Fi does not, it is tempting to treat the problem as a simple Wi-Fi failure. That conclusion is too broad. A phone or computer can successfully associate with a wireless network while failing to obtain a usable IP configuration, reach the router but not the wider internet, resolve domain names, … Read more
The Permission Problem Is Becoming the Main AI Problem AI agents are moving from systems that generate information to systems that can take actions. In September 2026, that distinction became harder to ignore as Meta rolled out Muse, a consumer-facing personal agent that can browse websites, fill forms, send messages, book services, and make purchases. … Read more
Buying more RAM is one of the easiest PC upgrades to misunderstand. A system with 64GB of memory sounds substantially more capable than one with 16GB, but the extra capacity does not automatically make applications open faster, games render more frames, or a processor execute work more quickly. RAM capacity primarily determines how much active … Read more
When people think about a data center, the visible story is usually about computing: servers, GPUs, storage, networking and the software running on top of them. The less visible story is what happens to the energy those machines consume. Almost all of the electrical power used by computing equipment eventually becomes heat. That heat must … Read more
Changing from one technology ecosystem to another can look deceptively simple. A person may buy a new phone, sign into an account, transfer their photographs, reinstall a familiar set of apps, and assume the transition is essentially finished. The visible data transfer is only part of what changes. A technology ecosystem is a collection of … Read more
For decades, the economics of computing were relatively easy to understand. A faster processor could finish a calculation sooner, a larger server could handle more users, and improvements in manufacturing generally meant that more computing power could be delivered for the same amount of money and electricity. Artificial intelligence is making that model more complicated. … Read more
A push notification can seem almost instantaneous. Someone sends a message, a sports score changes, a delivery status updates, or a security alert is triggered, and a few moments later a notification appears on a phone whose app may not even be open. It can feel as though the app itself is permanently listening for … Read more
A file can be stored on your computer, on an external drive, in a cloud service, or in several places at once. The confusing part is that these options are often presented as if they are interchangeable. They are not. Local storage gives you direct access to data on a device you control. Cloud storage … Read more
When you open a website, it is easy to imagine your computer sending a request directly to that website’s server. In reality, your request usually passes through several layers of networking before the destination ever sees it. Your router sits at an important boundary in that process. It connects your local network to another network, … Read more
Notifications are supposed to reduce the amount of attention required to monitor a device. Instead, once someone owns a phone, laptop, tablet, smartwatch, and perhaps a second computer, notifications can become a distributed system of their own. The same event may appear on more than one screen. A message might arrive on a phone and … Read more
