consumer tech, taken apart and explained
Random number generators, online draws, probability you can use, and a buyer's checklist for gadgets, explained without the marketing.
Shuffled playlists, game loot, encryption keys and online draws all depend on random numbers. Computers produce them in two very different ways.
DRAW-02From village raffles to televised lottery draws and five-minute keno-style games, every draw has to answer the same question: how do players know it is fair?
PROB-03Battery estimates, weather apps, spam filters and game odds all speak the language of probability. A few core ideas make them much easier to read.
TERMS-04Any app that holds your money has rules about getting it back. Reading them before you deposit is the cheapest consumer protection there is.
BUY-05Spec sheets are long and marketing is loud. A short checklist of what actually matters helps you pick a phone, laptop or pair of headphones you will still like in two years.
DATA-06The first hour with a new phone or laptop is the best moment to decide what it shares about you. A few settings make a big difference.
