Submission + - The LED is 50 years old (bbc.co.uk)

BoxRec writes: "The light-emitting diode has brightened our lives for half a century — from lighting up the city streets at night, to decorating Christmas trees each December.
The LED started life in October 1962, as a single red illumination in a General Electric research lab in New York state.
Prof Nick Holonyak Jr from the University of Illinois, takes a look back at how it all began with his invention of the first practical visible-spectrum light-emitting diode."

Comment Unity === Useless (Score 1) 798

I use Ubuntu for work and Unity is an unmitigated disaster. I receive reports in many different formats, PDF, DOC, JPEG, HTML, PNG etc and need to refer back and forth between them. Pre-Unity this involved glancing at the bottom tool bar and clicking the report name. With Unity - I have to stop and think, "where is the switcher" oh yes it's on the left. Move the mouse to the left and then wait for it to appear. Now I don't know what format the report is in so I have to start at the top with Firefox and work my way down the different programs. If I am lucky I only have a few reports in each format and if they are distinct I can spot the one I am looking for with ALT-TAB. However more often than not I have to switch into the report to see if it is the one I need. If I have more than say 15 reports open I can forget where I am and go around in circles looking for reports. This rigmarole takes forever and is mentally draining. I have swapped back to Gnome2 now and it's a great relief. Mark Shuttleworth - the man who snatched defeat from the jaws of victory

Submission + - First Electric Rolls Royce (bbc.co.uk)

BoxRec writes: "The first electric Rolls Royce has been built and at 2.7 tonnes it must be the heaviest electric yet. The luxury car is capped at 100mph and being a Rolls has a few extras to set it apart."

Comment Not Good (Score 1) 782

The biggest criticism from the rest of the world levelled against the USA forces in Afghanistan is that they are killing far too many civilians. This is also a bad tactic as general Stanley McChrystal admitted last year they were creating more insurgents by their actions not fewer. He called it the hearts and minds offensive and implemented new tactics involving less use of indiscriminate weaponry (bombing) and closer contact combat. This new weapon is non discriminatory, who knows how many women and children might also be taking shelter behind the wall with the gunman. Not good, not good at all .....

Comment Re:Guns don't kill people... (Score 1) 271

Murder rate per 100,000 of the USA at 5.5 is over three times that of the UK at 1.5 http://en.wikipedia.org/wiki/List_of_countries_by_intentional_homicide_rate IMO the UK is a much more violent society, street fighting is the weekend pastime in many towns. The only factor reducing the death rate is the absence of guns, so while stabbings are more common in the UK deaths are more common in the USA.
