Can Invisible Lasers Help Bridge the Digital Divide? I Toured This Futuristic Cell Tower to Find Out

I’ve written hundreds of articles about broadband internet technology, but I'd never heard about data being transmitted through invisible lasers before. This wasn’t the plot of a sci-fi movie. This was Taara, a graduate of X, Google’s Moonshot Factory, that uses beams of light to transmit data through the air at the speed of light. I drove 140 miles from my home in Seattle to remote Selah, Washington, to see it in action. Three miles up a rocky dirt road, you’ll find a typical cellular tower, d

Starlink operator SpaceX isn't getting the broadband money it demanded from state governments despite the Trump administration rewriting the rules of a $42 billion grant program. Instead of directing the lion's share of money to Elon Musk's space and satellite company, early results indicate that states still plan to deploy fiber broadband networks to most of their unserved households.

Coalton Playground: Type-Safe Lisp in Your Browser I wanted to share a side project I’ve been tinkering with for a while and finally got around to shipping: Coalton Playground – basically a web-based REPL for Coalton, which is this interesting statically-typed Lisp dialect. So What’s Coalton? If you haven’t heard of it, Coalton is kind of a weird (in a good way) mashup – it takes Haskell’s type system and plants it right in the middle of Common Lisp.

The healthy soda trend doesn't appear to be going away anytime soon. Last week, Pepsi announced that it will launch its very own soda packed with prebiotics in fall 2025.
