Comment: Electronics do interfere (Score 1) 220

by NivenHuH (#36276914) Attached to: Alaska Airlines Jettisons Paper Manuals For iPads
EMI from electronic devices do affect navigational systems. If you want a demo of this in your house, put your iPad next to a magnetic compass and watch it swing.

In the little Cessna that I fly, my portable GPS will cause the compass to be off by as much as 3-4 degrees.

I know this is much different than commercial jetliners -- I don't claim to know how commercial jet navigational systems are built. I do know that most of the FAA regulations (such as turning off portable electronic devices) are typically created from incidents that have happened in the past.

+ - Sun Releasing 8-Core Niagara 2 Processor

Submitted by Anonymous Coward
An anonymous reader writes "Sun Microsystems is set to announce its eight-core Niagara 2 processor next week. Each core supports eight threads, so the chip handles 64 simultaneous threads, making it the centerpiece of Sun's "Throughput Computing" effort. Along with having more cores than the quads from Intel and AMD, the Niagara 2 have dual, on-chip 10G Ethernet ports with crytopgraphic capability. Sun doesn't get much processor press, because the chips are used only in its own CoolThreads servers, but Niagara 2 will probably be the fastest processor out there when its released, other than perhaps the also little-known 4-GHz IBM Power 6."

No problem is so formidable that you can't just walk away from it. -- C. Schulz
