Technology History: Before Computers: Notched Card Databases via hack a day

It is always interesting to see how we did business before the introduction of cheap, portable computers. It also informs how we might better use computers and technology today. — Douglas

It is hard to remember that practical computers haven’t been around for even a century, yet. Modern computers have been around an even shorter period. Yet somehow people computed tables, kept ledgers, and even wrote books without any help from computers at all. Sometimes they just used brute force but sometimes they used little tricks that we’ve almost forgotten. For example, only a few of us remember how to use slide rules, but they helped send people to the moon. But what did database management look like in, say, 1925? You might think it was nothing but a filing cabinet and someone who knew how to find things in it. But there was actually a better system that had fairly wide use.

This DIY domino clock tells the time using three LED-lit tiles via Arduino Blog

After coming across Carbon Design Group’s Domino Wall Clock, which uses electronic magnetic coil motors to reveal white dots, Instructables member “Kothe” decided to create a simplified version of their own. The clock is comprised of three custom dominoes — the first tile for hours, the second and third for minutes. Unlike its inspiration, Kothe’s device uses addressable RGB LEDs as dots that allow for a variety of colors to shine through.

Onion Pi makes your web traffic anonymous via Open Electronics

Hmmm, might be an easy (and relatively cheap) way to play around with Tor and learn a bit more about this anonymizing service. -- Douglas Adafruit’s Onion Pi is a Tor proxy that makes your web traffic anonymous, allowing you to use the internet free of snoopers and any kind of surveillance. Follow Adafruit’s tutorial on setting up Onion Pi and you’re on your way to a peaceful anonymous browsing experience. Tor is an onion routing service – every internet packet goes through 3 layers of relays before going to your destination. This makes it much harder for the server you are accessing (or anyone snooping on your Internet use) to figure out who you are and where you are coming from.
