Sequoia is the world’s fastest supercomputer (used for weapons testing)
By Charles Arthur | Guardian.co.uk
The US is back at the top of the supercomputing leagues for the first time in almost three years, reclaiming the title from Japan, thanks to a new system developed by IBM.
The computer, Sequoia, uses IBM’s BlueGene/Q servers and at the US Department of Energy’s Lawrence Livermore National Laboratory it achieved 16.32 petaflops – trillions of floating-point calculations per second – using more than 1.5m processor cores.
Sequoia is also one of the most energy-efficient systems on the biannual Top 500 list which ranks the world’s known supercomputers, released on Monday.

Sequoia will simulate nuclear explosions to a degree that was previously impossible, but it will also give researchers insight into what’s happening to weapons in the country’s weapons stockpile without actually testing nuclear bombs.
“Supercomputers such as Sequoia have allowed the United States to have confidence in its nuclear weapons stockpile over the 20 years since nuclear testing ended in 1992,” Lawrence Livermore said in a statement.

Increased tax subsidies for politically correct media
On Dec 9 last year I translated a random snapshot of the biggest newspaper in Sweden. The headlines alone spoke for themselves. It was, simply put, an orgy of political correctness, obvious attempts at emotional manipulation and general national self-loathing. In other words, a typical Swedish newspaper on any given day.

Facebook completes first drone flight above UK, Mark Zuckerberg confirms
Solar powered drones which provide internet access to rural and remote areas have been trialled in UK for first time by Facebook.
They â€śhave a wingspan greater than a Boeing 737 but will weigh less than a carâ€ť, according to the social network's chief Mark Zuckerberg.
The drones, developed by Somerset-based company Ascenta which Facebook bought last March, will beam down laser-guided ...
