Tech Pulse 3/9/26

This week on Tech Pulse, we narrate three articles spanning navigation technology, Apple history, and budget consumer hardware.GPS is under siege. Cheap jamming devices are blinding ships, planes, and guided weapons — and a reporter surveys the scramble to replace a system the world built everything on. The answer, it turns out, isn't one technology. It's several working together.A new book traces Apple's fifty years from a Silicon Valley garage to a four-trillion-dollar company, with all the near-deaths and unlikely pivots in between. A reviewer finds the origin stories riveting — and the recent era frustratingly guarded.Apple is back in its candy-colored era, with a budget laptop and an entry-level iPhone aimed at younger buyers. A reporter asks whether cheerful design and a lower price tag can paper over the hardware compromises — and whether the whole strategy is shrewder than it looks.
