New top story on Hacker News: Ask HN: How do you do home surveillance?

Ask HN: How do you do home surveillance? 12 by teniutza | 7 comments on Hacker News. In this age of IoT where devices are being taken over by strangers and (service) companies are storing clear-text passwords, how do you manage your home security? I'm talking less about motion sensors and door/window open/close sensors, and more about video surveillance. I want to add a couple of IP cameras but I'm completely petrified by the thought of someone getting access to a live feed from my house, due to the negligence of the service provider. I've looked around and there are plenty of options for IP/Wi-Fi cameras with a tone of cool features, which can be accessed through a smartphone app, which, of course, is handled by the manufacturer (feed goes through its servers). What I'd like is an IP camera that provides an API to which I can connect from my home server and let me see the feed only trough it. Motion sensing is also a cool, and useful feature, as it would allow me to...

How to build your own supercomputer!!

The term “supercomputer” is a loose one. There’s no official definition, so there’s nothing preventing you from applying the term to your desktop PC, laptop or digital watch. Broadly, though, it refers to a computer that’s much more powerful than the typical hardware of its period. The first supercomputer is often said to be the CDC 6600, designed in the early 1960s Seymour Cray (whose name would become synonymous with supercomputing). It could perform calculations at a rate of around one megaflops – that is, one million floating- point arithmetical operations per second; roughly five times the performance of a contemporary mainframe such as the IBM 7090. Today, the term might refer to a system such as the Fujitsu K computer, capable of more than ten petaflops – a staggering ten-billionfold increase over the original Cray. The two aren’t perfectly comparable since the two systems performed quite different tasks, but it’s clear we’re dealing with vast amounts of power. Supe...
