Mind-reading machine knows what you see

It is possible to read someone's mind by remotely measuring their brain activity, researchers have shown. The technique can even extract information from subjects that they are not aware of themselves.

So far, it has only been used to identify visual patterns a subject can see or has chosen to focus on. But the researchers speculate the approach might be extended to probe a person's awareness, focus of attention, memory and movement intention. In the meantime, it could help doctors work out if patients apparently in a coma are actually conscious.

Scientists have already trained monkeys to move a robotic arm with the power of thought and to recreate scenes moving in front of cats by recording information directly from the feline's neurons (New Scientist print edition, 2 October 1999). But these processes involve implanting electrodes into their brains to hook them up to a computer.

Now Yukiyasu Kamitani, at ATR Computational Neuroscience Laboratories in Kyoto, Japan, and Frank Tong at Princeton University in New Jersey, US, have achieved similar "mind reading" feats remotely using functional MRI scanning.

In a separate study, also published in Nature Neuroscience, John-Dylan Haynes and Geraint Rees at University College London, UK, showed two patterns in quick succession to 6 volunteers. The first appeared for just 15 milliseconds - too quick to be consciously perceived by the viewer.

But by viewing fMRI images of the brain, the researchers were able to say which image had been flashed in front of the subjects. The information was perceived in the brain even if the volunteers were not consciously aware of it.

Firefox OS media-casting stick strikes Kickstarter gold

The first Firefox OS based media player has arrived on Kickstarter, in the form of a $25 open-spec HDMI stick that supports Chromecast-like content casting. The Matchstick, which has already zoomed past its Kickstarter campaign’s $100,000 funding goal, with 28 days still remaining, was teased back in June by Mozilla developer evangelist Christian Heilmann. The unnamed prototype was billed as an open source HDMI stick that runs Mozilla’s Linux-based Firefox OS and offers casting capabilities. Few details were revealed at the time except that the device used the same DIAL (DIscovery And Launch) media-casting protocol created by Netflix and popularized by Google’s Chromecast. Read more

Open source history, present day, and licensing

Looking at open source softwares particularly, this is a fact that is probably useful to you if you are thinking about business models, many people don't care about it anymore. We talk about FOSS, Free and Open Source Software, but if we really are strict there's a difference between free software and open source software. On the left, I have free software which most typically is GPL software. Software where the license insures freedom. It gives freedoms to you as a user, but it also requires that the freedoms are maintained. On the right-hand side, you have open source software which is open for all, but it also allows you to close it. So here we come back to the famous clause of the GPL license, the reciprocity requirement which says, "If I am open, you need to be open." So software that comes under the GPL license carries with it something that other people call a virus. I call it a blessing because I think it's great if all software becomes open. Read more
