Depends... It is possible to get intra-grid oscillation where a phase shift (a phase angle between various points of a large grid is natural and inevitable) starts to destabilise and if the oscillations are not damped by modifying power input in the right places, then things can get bad pretty quick. This is in the UK which is tiny in comparison to the US. Question - is the US national grid one big AC system or a number of smaller networks with DC interconnects[1] [1] DC interconnects are the classic solution to allowing power transfer between grids without requiring syncronisation - eg the GB has DC interconnectors with Ireland, France and the Netherlands. See here http://en.wikipedia.org/wiki/East%E2%80%93West_Interconnector

Seriously... If you dispense with use strict/use warnings it handles pretty much like basic with a hint of structure. I was asking exactly the same question the other week with regard to what to start my daughter (aged 7) off on. I went through some mental deliberations and settled on perl. She's taken to it as well as I did Sinclair BASIC at a much older age, She can't write anything from scratch (that would be expecting a LOT of such an age group) but she is happy to type in a short dictated program. She chooses the subject (times tables, Fibbonnaci etc) and I work out a strategy for building the program up a few lines at a time, with it being runnable as often as possible. She's demonstrated that she can modify it for basic parameters, eg which "times table", "max size of Fibbonnaci number). The best one we've done to date is one that picks 2 random numbers and asks a question like "What is X times Y?" It prompts for an answer and checks it with a friendly "yea" or "bad luck" message. It's not pretty, it's not trendy, it's not GUI but in my humble opinion, she is learning what computers can *really* do.

Secret Service Runs At "Six Sixes" Availability 248

PCM2 writes "ABC News is reporting that the US Secret Service is in dire need of server upgrades. 'Currently, 42 mission-oriented applications run on a 1980s IBM mainframe with a 68 percent performance reliability rating,' says one leaked memo. That finding was the result of an NSA study commissioned by the Secret Service to evaluate the severity of their computer problems. Curiously, upgrades to the Service's computers are being championed by Senator Joe Lieberman of Connecticut, who says he's had 'concern for a while' about the issue."

Police Called Over 11-Year-Old's Science Project 687

garg0yle writes "Police in San Diego were called to investigate an 11-year-old's science project, consisting of 'a motion detector made out of an empty Gatorade bottle and some electronics,' after the vice-principal came to the conclusion that it was a bomb. Charges aren't being laid against the youth, but it's being recommended that he and his family 'get counseling.' Apparently, the student violated school policies — I'm assuming these are policies against having any kind of independent thought?"

Wii Hardware Upgrade Won't Happen Soon 325

As high-definition graphics become more and more entrenched in this generation of game consoles, Nintendo has had to deal with constant speculation about a new version of the Wii that would increase its capabilities. Today, Nintendo of America president Reggie Fils-Aime bluntly denied that a hardware revision was imminent, saying, "We are confident the Wii home entertainment console has a very long life in front of it." He added, "In terms of what the future holds, we've gone on record to say that the next step for Nintendo in home consoles will not be to simply make it HD, but to add more and more capability, and we'll do that when we've totally tapped out all of the experiences for the existing Wii. And we're nowhere near doing that yet."

NFS is 1) a block device

No, it's a Network File System (hint, the initials). NFS supports filesystem primitive operations - see: http://tools.ietf.org/html/rfc1094 Networked block devices are possible, but NFS isn't one of them. However, some of the points are still valid - unix doesn't particularly like it when mounted filesystems go away unexpectedly.
