The main reason Iran is negotiating on weapons is that the Iranian people elected president Rouhani. They were sick of Ahmadinejad clownish posturing and hostility to just about every other nation. Sanctions are having wearing effect on Iranian families and they didn't see an improvement in future as long as a leader like Ahmadinejad ( although he was not standing again ) was in power. The Iranian people elected a moderate with a mandate to improve Iran's foreign relations and that is what is happening. We will see a lot more of this in the months to come and more of Israel's attempts to derail any agreements.

how many of these people realise that just driving around with a smartphone gives away more information about your movements than a squadron of drones could ever collect. You would be better off shooting your phone instead.

LFB attend all significant incidents as Heathrow, as they did today. LFB has extra appliances and manpower available at all the stations surrounding Heathrow, including Ruislip, Hayes and Hillingdon and can call on appliances from across London and neighbouring fire authorities. The shutdown today was not due to a lack of resources.

This one would be embarrassed but it can't remember what it idid last night.

Yes but I never thought the Raspberry Pi would make a very good physical computing resource for classrooms, for hackers yes, kids not so much. The Arduino and clones provide analogue in, PWM for servo etc. and most importantly buffered i/o ( I think the Beagle Bone Black also does all this ). Speaking as someone who made magic smoke from a BBC Micro RS232 board while at school, I think it would be just too easy to kill the Raspberry PI with its 3v3 logic ( TTL would kill it, off course ), max 50ma out and i/o unbuffered to the SOC. Just wiring up an LED without a ballast resitor might do it, how many times would that happen in class.

I think what would suit schools even better would be a virtualised x86 version of the Raspberry Pi distribution ( raspbian ). That way they wouldn't need to buy new hardware or replace their PCs windows operating systems. The virtualised Pi would have a low memory, disk and cpu footprint so would sit confortably on the often old PCs I have seen in secondary schools. Programming could be done in the virtualised Pi but the PC would still be available for other classes to run Photoshop or MATLAB, Pro Tools or whatever.

Kids could transfer their work from a Rasperry pi at home to the virtualised one at school. The only sticking points would be anyone starting to use Open GL / open GL ES could run into problems.
