OpenLase: open realtime laser graphics
First of all, as I’m sure everyone knows by now, I’ve been working on hacking the Kinect and writing open drivers for it. There’s a website for the community and a Git repo with the code, and it’s working fairly nicely by now.

With that out of the way, here’s a project that I’ve been working on on-and-off for the past year or so. I’ve been interested in laser scanning and DIY laser projectors, but I couldn’t find any good open source software to drive them. Specifically, I was interested in the realtime aspect: rendering and showing dynamically generated images and responding to events, not just making and preprocessing laser shows. So I set out to write my own set of software to do real-time rendering. This was the result:

I'll be building one of these @ hacdc this week.

Starving Student hybrid

Two monkeys with tiny sensors in their brains have learned to control a prosthetic arm with only their thoughts, using it to reach for and grab food and even to adjust for the size and stickiness of morsels when necessary, scientists reported Wednesday.

OMFG the robot future is here.

We present a prototype system that can be used to capture longitudinal socialising processes by recording people's encounters in space. We argue that such a system can usefully be deployed in prisons and other detention facilities in order help intelligence analysts assess the behaviour or terrorist and organised crime groups, and their potential relationships. Here we present the results of a longitudinal study, carried out with civilians, which demonstrates the capabilities of our system.

Frighteningly bad science.

The idea was that these two physicists wanted to help figure out a way to track prisoners who might be up to no-goodery. Ideally they'd put RFID's into every prisoner's ass and then watch and track the no-gooders. Then after some statistical modeling magic they'd be able to know that prisoner A spends a lot of time humping prisoner B.

That's all fine and dandy, but the PoC implemented about wasn't tested in prisons. It was tested on the the people who live in and around the town of Bath, UK using the resident's bluetooth devices. They have plots and models in their paper showing off some awfully frightening ideas.

So their original idea has nothing to do w/ the implemented idea except for all the spying.

I love arxiv. This is a blog that sort of treats arxiv like a journal club.
