Perhaps I should have titled my post "It's a computer problem, etc.". Again, in your scenarios, it's a computer with a USB wireless device, or a contractor's laptop, not the PLC. Wireless PLC networking, when used at all, should be limted to discreet and analog I/O functions which under most hardware protocols are MAC address specific and pretty hard to spoof.
With managers demanding global plant performance data in real time, it is vital to build security into the interface networks. The PLC's are just dumb relay-replacements in most cases. The challenge is in the SCADA/Distributed Controls architecture and getting IT guys who know nothing about automation to understand the limitations.
Enterprise, like my ship the Long Beach, had "Top Hat Areas" immediately above the RC's where access cuts were made and re-sealed folllowing refuelling or repairs, much like the standard pressure hull cuts made in submarines under overhaul. Source: NavNuPwrSchMareIs Class 73-06:)
The "Big E"'s first combat deployment was in the Gulf of Tonkin, on Yankee Station. As a veteran of TF77 (The Tonkin Gulf Yacht Club) I find it appropriate that her last cruise will another Gulf...the Persian. Too bad there's nothing to compare to Subic Bay in the Mideast for R n' R.
has never been mugged, burgled, or had a loved one raped or murdered. GPS won't stop Homie da Gangsta from jacking up my car or gang-raping your sister, but barbed wire and bars will. There is no cure for the near-100% recidivism of violent felons except death or life imprisonment.
nothing. What have we done since Apollo? Fly around in circles in aging, dangerous jalopies. Big deal. We don't have a space program, we have a low earth orbital grocery delivery and appliance repair service. Whoop-de-friggin-do.
Zombies have always been, and always will, be with us because of 1) Organized Religion, 2) Trade Unions, 3) Nation States, and 4) Marxist Collectivism. Only enlightened anarchy can spare us.
A more practical issue is the relationship of science to politics. The Great Unwashed will always blindly go along with whatever pablum the Party du Jour feeds them. Intelligent, reasonable change will occur only when scientists understand that good public relations has very little impact on actual policy. We won't even open the packet of freeze-dried preserved worms related to the capacity and willingness (or lack thereof) of power-mad professional liar class to understand and act wisely on what they're being told.
Considering the AoE of a large impact, any target located in the central Middle East would be an enormous boon to world peace and stability. No more "holy" cities and shrines to fight over. Imagine, world religion wiped out by an act of "God"!
Believe it or not, you needn't throw the engineering baby out with the unrewarding specialty bathwater. Got a talent for gadgets? Like to tinker with cool toys? Occasionally actually get dirty? Really blow something up once in awhile? Try looking about in the field, see what industries you might enjoy. I've gone from SCADA design to manufacturing automation, chemical process development, and now I do biotech instrumentation design. Sometimes it takes some guts to jump into a new discipline, but as they say, no guts=no glory.
So long as the tax code is a reelection vehicle for incumbent legislators and mechanism for social engineering, we will never see a rational taxation plan.
Something as fair and simple as a national sales or VAT tax removes too much power from the arseholes we habitually elect and reelect. It will never happen.
Except geographically, the residents of DC differ from the general population...how?
Elections are just a set of declared variables. It is only a matter of whichever collection of fools > the the total number of fools elects whatever group of crooks/incompetents/egomaniacs wherever.
I worked for BP's orphan photo-voltaics lab in Toano, Virginia long enough for us to be featured in their big "Beyond Petroleum" advertising blitz...and then poof! they pulled the plug. Although we were doing first-rate science and pilot production of amorphous silicon PV cells, we were left with the impression that we were merely a "green" marketing asset left over from the Amoco merger.
We supplied the green paint, then they threw away the brush. So goes the oil business.
Yo, yo, yo, we be down wit da boyz! All dat science is just a lotta noyz! We be checkin out da hos while we pimp our ridez We don't give a fsck about improvin' our minds!
Comes the new day, the equitiy holders in the great global financial institutions will open their Times (London, NY, w/e) over breakfast and nod approvingly. The scions of dynastic family fortunes will still have their way, and the underlings who do their bidding will function exactly as yesterday.
I will learn of the outcome accidentally and not care one bit. I will simply be satisified knowing that I have again not soiled my hand by endorsing any of the liars, cheats, lackies, and demagogues on the ballot. They are all, without exception, scum.
We don't get to vote for the people who really make a difference in our lives. We do, however, get to vote for our own personal honor.
I, for one, welcome our new PS3 Everquest overloads. I'm not optimistic about the quality of a Sony-produced PS3 EQ implementation, but I'm willing to give Sony a chance to let a 3rd party team re-develop the brand. Wasn't some Korean shop doing something called Never-Ending Saga along these lines? EQOA (after the Frontiers expansion) for the PS2 was a nice platform for it's time, but aside from minor tweaks and a few occasional bits of new event-based content SOE seemed to let it rot on the vine once they had a profitable player base. Pity, because it was a great community in it's day. This is coming from a rather gimp but fun-loving 60 Shadow Knight on Ferran's Hope.:)

Einstein is still right, and Karl Marx is still dead. Nothing to see here folks, move along.

Bravo Zulu, CVN-65
It isn't as though there's anything in the NYT that isn't freely available on Salon, MoveOn.org, or the Huffington Post.

Buy a new printer every time the ink runs out, donate the old one to a school or charity for the tax credit.

I dare say that, he having been dead for several years, Dr. Sagan's health problems are a good bit more severe than Prof. hawking's.

Ah, but are his deposits insured by the FDIC?
Or is the government being forced to bail out his bank?
Like all U.N. mandates, resolutions, and policies, this too will be universally ignored,
Except, of course, where it serves the ulterior interests of an actual government or the public relations purposes of a crusading Hollywood celebrity.

Don't thank Jesus, my friend. It's named for an Anglo-Saxon god of blacksmithing. :)
