USB C cables all look the same, so how does your computer know the difference between them? Turns out there’s a tiny chip inside most USB C cables that identifies its capabilities. Someone made an open source app that uses that chip to list out the info so you never have to confuse cables again.

You can text someone hundreds of miles away with no cell service, no wifi, and no servers in between. All it takes is a cheap radio board and open source software like Meshtastic. Meshtastic turns the board into a node in an encrypted mesh, capable of receiving and relaying information across vast distances.

Why are some HDMI cables insanely expensive? Turns out there is a distinct difference between a $20 cable from Walmart and a fiber optic HDMI. Rather than using copper wiring, fiber optic cables convert video signals into light pulses which improves quality and signal at long distances.

Siri doesn’t listen to words, it listens for frequencies. In order to stop millions of Apple devices from activating during a keynote, Apple cut those frequencies from the live audio. We put that audio into a spectrogram in order to visualize the alteration.

Your fiber optic cables can technically hear you through walls. Using the deformations in fiber cables caused by sound waves, researchers engineered a way to rebuild and record speech. The setup requires complex equipment and direct access though, so it’s unlikely to be used for surveillance.

Ads don’t come attached to websites, they are loaded from a different server. So there’s a way to stop them from ever loading onto your network. Using a raspberry pi and some free software, you can stop ads from getting into your home. It’s called a pi hole and it acts as a catch between your home internet and the servers that place ads on websites.
