Cloud Mirror is an interactive art installation that combines you and your easily available online information in real time. Attendees stood in front of the camera and held up their badges. Cloud Mirror then projected them on the wall and displayed a speech bubble containing information from the web. In the example after the break, you can see our very own [Eliot] displayed with his most recent twitter post. To add another layer to it, you could send a text message with someone’s badge ID to the system and it will display your message in that person’s bubble.
Though Time won’t admit it, their poll on the most influential person was hacked. Moot, the founder of 4chan is rated #1. Not only that, but if you read the first letters of the poll results, you get “Marblecake also the game”. This refers to the IRC Chanel where many 4channers congregate as well as “the game” an internet meme. This article is very interesting as it delves into the details of the attack. Focusing mainly on what happened when the autovoting software was shut down due to reCaptcha. you’ve probably seen reCaptcha before. It presents you with two words, made difficult to read by strange kearning, warping, and squiggles. If you can read it, you’re most likely a human. Anon, a common name for 4channers, first tried to hack reCaptcha.
Their attempt at hacking reCaptcha relies on the process reCaptcha uses to identify words. It presents you with two words, one of which it already knows. The other is compared to a database of common responses to that word. Anon decided that if they entered “penis” enough times, they could flood the database allowing their autovoter to function again. This, though clever, was unsuccessful. They eventually settled on manual voting. This was taking too much time, they feared they would never reach their goals. To help with this, they built a simple interface that would preload several reCaptchas and cue up votes. This streamlining allowed them to squeak in the votes they needed to accomplish this.
It’s also worth noting that Time didn’t close the vote entries when the poll closed. They removed the poll from their site, but the streamlined vote software was still working. Anon is a powerful force of nature. If only we could harness it to cure cancer or HIV.
A few months ago, we introduced the SheevaPlug, a 1.2GHz ARM processor with 512Mb of RAM, 2 usb ports, an ethernet port, and an SD card slot. In that article, we asked: “What would you do with one?”. We received tons of responses, 118 comments and counting. Scientific American had a similar idea and asked some “hackers”(MIT students) what they would do with it (thanks, grisspy). We thought maybe we would weigh in with our opinions. Join us after the break and in the comments.
This guitar bot is part of the Legue of Electronic Musical Urban Robots, or LEMUR. As you can see in the video, it has 4 strings, each mounted on it’s own unit. The pitch is controlled by a sliding bridge, while the strings are plucked by a series of picks mounted to motor. The sliding bridge is quite fast, being able to shift 2 whole octaves in a quarter of a second. The final effect is quite nice, we would listen even if we weren’t watching a robot work. This is the kind of thing we should expect to see at the Guthman Musical Instrument Competition.
