But such a device consumes a lot of current in the battery bank. The basic arithmetic …

It's quite satisfying to make your tech feel like yours. From a custom keyboard with special keycaps, to a PC build that you've carefully selected the cable routing for, to a laptop that's stuck with a story of stickers customizing makes those devices less of a generic gadget and more …

Imagine the following scenario: three countries, a fleet of refrigerated trucks with pharmaceutical products, all of which are tracked in real time by a system of GPS trackers and temperature sensors. It is the dream of a logistician, and until such a data stream is intercepted. Cargo locations are suddenly …

Consider, when last did you use your phone to make payment, or when you observed a heartbeat of a patient displayed on the screen of a medical device. We engage with technology to the extent that we can now forget that it is an impressive amount of craftsmanship that is …
