How big a solar battery do I need to store all my home's electricity?
I have a modest set of solar panels on an entirely ordinary house in suburban London. On average they generate about 3,800kWh per year. We also use about 3,800kWh of electricity each year. Obviously, we can't use all the power produced over summer and we need to buy power in winter. So here's my question: How big a…

Tracker Beeper (2022)
A week ago, I finally got round to implementing an idea I’d been toying with for years: what if your computer made a little bit of noise every time it sent data to Google? From studying logs, I’d long known just how many sites send all your visits and clicks to (at least) Google, but a log that you have to manually…

Intel will add deep-learning instructions to its processors
Some of the latest Intel processors support the AVX-512 family of vector instructions. These instructions operate on blocks of 512 bits (or 64 bytes). The benefit of such wide instructions is that even without increasing the processor clock speed, systems can still process a lot more data. Most code today operators…
