G.fast is a hybrid-fibre technology, which is designed to deliver Internet speeds of up to 1000Mbps over shorter runs of copper cable (up to around 250 meters via 106MHz+ of radio spectrum). The idea is that a fibre optic cable is taken closer to homes and then G.fast works to deliver the last few metres of service, which saves money because the operator doesn't have to big up your garden to lay new cables.
By comparison XG-FAST works in a similar way but via an even shorter run of copper and using frequencies of up to 500MHz. For example, XG-FAST delivered its top speed of 10,000Mbps by bonding two copper lines together over just 30 metres of cable. But this might be a problem for commercial operators, which will want to maximise profits by using more copper to reach more homes and not less."
If the system is down so far as needing that, then it's already crashing i'd suspect. There are no parachutes as a failsafe either.
I give you SAS flight 751. Both engines out, no power to the instruments. "Landed" using the windows and a mechanical artificial horizon. No fatalities (but a few severe injuries, unfortunately).
An autoconfig ipv6 address is the mac with some static bits shoved on.
Not anymore. Practically everyone implements the privacy extensions, and most do not generate a MAC-based IPv6 address at all.
It's great that you foresaw it all. That does not really have anything to do with what I wrote.
Obama seems to be the first mainstream US presidential candidate in a long time to "talk the talk" to the kind of people who read Slashdot. The others have been spouting ignorant crap or simply ignoring the topics that most Slashdotters care about. Therefore Obama is the first president that we can be disappointed in -- the others were known bad before they became presidents.
File system drivers in general are not properly security vetted. You can do interesting stuff to a Linux box if you put ext4 on a fake device and start messing with what is on the disk while it is being read. Many device drivers have similar problems; you could find a Linux device driver with a problem and make a fake piece of hardware resembling the real thing while exploiting the bug.
This is pretty much unfixable. While most core OS code is of a high quality these days, there is just too much driver code around. A proper audit is infeasible.
Besides, Thunderbolt makes it pointless. With Thunderbolt, you do not need to exploit anything, the bus provides you with unlimited access.
It is a sad state of affairs really.
“The new plants will run at current prices, but they won’t cover their costs” said Ricardo Klimaschka, a power trader at Energieunion GmbH. Lower prices “leave a trail of blood in our balance sheet” according to Bernhard Guenther, CFO at RWE, Germany’s biggest power producer. Wind and solar’s share of installed German power capacity will rise to 42% by next year from 30% in 2010. The share of hard coal and lignite plant capacity will drop to 28% from 32%."
