5th Generation WIFI, 802.11ac

Five years have passed since the first 802.11n devices implementing a draft of the now-finalized specification hit the market. Over the years 802.11n support has become ubiquitous in the industry. Everything from smartphones to high-end notebooks support the standard. Even low cost products like the $99 Apple TV or $49 Roku LT ship with 802.11n support. With real world transfer speeds ranging from 30Mbps at the low end to 150Mbps at the high end, 802.11n is simply too slow to quickly move large files. It wasn’t too long ago that 100MB/s was reserved for high-end hard drives in PCs. Today, with SSDs capable of sustaining transfers of over 500MB/s, the bottleneck in many wireless homes is increasingly becoming WiFi.

Supercomputers aren’t what they used to be. The Chinese are building a supercomputer with their own microprocessors, shunning American chip giants Intel and AMD. The Spanish are building one with cellphone chips. And this week, the San Diego Supercomputer Center (SDSC) officially plugged in the first supercomputer that uses flash storage rather than good old-fashioned spinning disks.

Naturally, they call it Gordon. As in Flash Gordon.

Pastor orders church leaders off Facebook

Church of Facebook

Thou shalt not commit adultery. And thou also shalt not use Facebook.

That’s the edict from a New Jersey pastor who feels the two often go together.

The Rev. Cedric Miller said 20 couples among the 1,100 members of his Living Word Christian Fellowship Church have run into marital trouble over the last six months after a spouse connected with an ex-flame over Facebook.
Because of the problems, he is ordering about 50 married church officials to delete their accounts with the social networking site or resign from their leadership positions. He had previously asked married congregants to share their login information with their spouses and now plans to suggest that they give up Facebook altogether.

‘Racetrack’ Magnetic Memory Could Make Computer Memory 100,000 Times Faster

Racetrack Magnetic Memory

Annoyed by how long it took his computer to boot up, Kläui began to think about an alternative. Hard disks are cheap and can store enormous quantities of data, but they are slow; every time a computer boots up, 2-3 minutes are lost while information is transferred from the hard disk into RAM (random access memory). The global cost in terms of lost productivity and energy consumption runs into the hundreds of millions of dollars a day.
