A look at the (now patched) security of [Kim Dotcom's] MEGA cloud storage service

mega-cloud-storage-security

MEGA is a new, encrypted cloud storage system founded by [Kim Dotcom] of MegaUpload fame. They’re selling privacy in that the company won’t have the means to decrypt the data stored by users of its service.

Messenger bag LED matrix keeps bikers safe at night

messenger-bag-led-matrix

Get a little more exposure than one under-saddle bike light can provide by building your own LED enabled messenger bag. It looks like the bag itself was fabricated from scratch by [Andrew Maxwell-Parish] rather than altering an existing bag. He had a few goals for the project, the most interesting of which was to make the electronics removable. His … Read the rest

Many models have room for a double DIN, which is defined as 4″ high by 7″ wide. Once [Meta James] figured out that the dashboard bezel … Read the rest

Genetic algorithms become programmers themselves

AI

[Kory] has been experimenting with genetic algorithms. Normally we’d expect his experiments to deal with tuning the variables in a control system or something, but he’s doing something much cooler. [Kory] is using genetic algorithms to write computer programs, and in the process bringing us one step closer to the Singularity.

The first experiments with genetic algorithms generating applications … Read the rest

Building a velocity sensitive keyboard

keys

Cheap toy pianos don’t usually have MIDI, and getting a velocity-sensitive keyboard from something out of the toy aisle at Walmart is nearly out of the question. If you’re willing to tear one of these toy pianos apart and build your own control electronics, though, the sky is the limit, as [JenShen] shows us with his home built velocity sensitive Read the rest

This man will take your picture while macing you

pepper

Odds are you don’t have a photographic memory, so if you ever have to mace someone, you probably won’t remember exactly what your attacker looks like. Compound that with talking to the police and looking at a few dozen mug shots, and it’s highly unlikely you’ll ever be able to identify the person you maced. This was the problem [John], … Read the rest
