Properly shielded equipment uses different methods to 'break the cage'. It's been many decades, but some of the heavily shielded designs I did in the 80's involved opto-isolators. Yes, that's right. Want to avoid radiating information ? Use light.

Keep in mind that the structure of the faraday cage depends on the frequency of the data being transmitted. It does not have to be unbreakable tin foil. Properly sized metal mesh will also do the job. Just ask anyone who tries to get a Wifi signal through an old wall with expanded metal lath and plaster.

Yep. Ditto. I still recall one young smartass demonstrating to our boss that he could display what was on the Boss's computer monitor from about 30 feet away with an antenna and a circuit he built with a breadboard.

A faraday cage IS the only way to protect against this with 100% reliability.

Comment: Misleading- Good will is common accounting (Score 5, Interesting) 255

The implied assumption in the article and in the commentary indicates a deliberate misdirection or a simple understanding of the accounting principles involved in how a business accounts for a BAD DECISION. Every business has the ability to use this 'loophole'. But it's not a 'loophole'. It's a simple recognition that a capital purchase that turns out to not be a good deal should have the loss (cost of the purchase price minus the fair market value of the asset) amortized over the book life of the asset against the income produced by the asset.

Kids, this is basic accounting 301 (Intermediate management accounting). Most accountants will tell you that having good will on your books means you made a dumb decision at some point, and paid more than something was worth. The title SHOULD read:

"Ballmer pays twice what Basketball team is worse, can't write it off immediately, has to wait 15 years."

Because I BUILT my first personal computer in 1976.

I keep an encrypted online database of my passwords. Sort of. I use a 'modular' password. One word is different, the other is always the same. So in my will I have the same word (and it's l33t combinations) written down, along with the address of the database. So anyone dealing after my death will know ALL my codes. My wife of 30+ years also keeps a copy of it, and knows the super secret codes.

I started this after being in a coma, and my wife having to deal with my PDA bleeping about meetings to her until the battery died. Which made her cry even more.

Good approach. Making a mortal enemy of the outgoing sysop, or simply his object of scorn, will screw you badly.

Other than to say "you're screwed", the big step is to also ramp up the professionalism and start building a better system governance policy and documentation process. The best way to explain that to management is to ask "Do you fail the Hit By a Bus Test? ".... If your key administrators are hit by a bus, will your systems go dark ?

I'm so right hand dominant that, when I shattered my right arm, my wife was the first to notice it (docs in the ER did not... I had a traumatic brain injury and in a coma... you do the fatality inducing stuff first). I was flailing around with my left hand only. They pooh poohed it. She said "You don't understand. He's so right handed that you could cut his left hand off and he wouldn't notice for hours and hours.) .

Agreed, but I'd go for full E and B field senses... and the neural net to be able to understand intercepted brain waves from other devices and creatures around me.

Sense of smell is somewhat over-rated. I lost mine for almost a decade, and haven't really gotten much of it back. Smell is a warning sense (Don't eat that ! Mate with her !) , not a critical information processing sense. Which is why the simpler part of the brain handles it.

I worked on a much more advanced and ultimately classified project for the Navy SEALS that produced a 'first shot kill' gun sighting system for the SEALs in ... 1993. The sight was designed to go on crew served weapons and sniper weapons. It included aim point calculation, full ballistics computing, sensors, range finder, thermal and optical sighting, low light level, yadda yadda yadda. At the time the sofware was required to be ADA (thanks, DOD).

Just because you put a shiny Linux on something doesn't make it all new and stuff.

Bingo. I can recall being in the research reactor at U Mo in Columbia in the early 1970's. People forget how accessible facilities were before 9/11 . Apparently we're so used to the Police State that we've created that it's pretty much taken for granted.

Which is a great pity. The less accessible cool research is for our children, the less interested our children will be in becoming cool researchers. Big Bang Theory and Mohawk Guy nonwithstanding.

A quite logical extension of such thinking. When it comes to liberty of thought, the road to Orwell's 1984 is paved with 'good ideas' gone wrong.

In the late 1970's I purchased a copy (paper) of "the Anarchist's Handbook". Why ? I was doing research for a story I was writing for a Creative Writing class in college. I already *knew* how to make explosives.. I was an Engineering student !

Criminalizing people for their knowledge would mean that pretty much every Engineer will end up in jail. Yeah... that will definitely not help a modern world.

Early each day on the steps of the Courthouse
The little old lawyer comes
In his own special way to the people he calls
Come buy my bags full of briefs
Come sue the little birds
Show them your greed
And you be glad if you do
Their young ones are too fat
Their nests all need stripping
All it takes is a lawsuit from you---u

Sue the birds, a million a chirp
million, million, million a chirp

Sue the birds, that's what he cries
while overhead, bird guano fills the skies

All around the courthouse the judges and bailiffs
look down as he sells his wares
although you can't see it
you know they are frowning
each time someone shows his gre--ed

Comment: Largest problem is Multiple Docs, one Patient (Score 1) 134

by cbelt3 (#39099581) Attached to: Study Says E-prescription Systems Would Save At Least 50k Lives a Year

My wife works in Assisted Living. She's had many situations where residents have shown signs of mental or physical degradation because of medication interactions. Not because one doctor prescribed interacting drugs, but because separate doctors prescribed interacting medications. The multi-specialist medical industry assumes that the patient is a medical expert, and can keep track of their medications AND know the interactions. All responsibility is in the hands of the patient. And guess what ? Most of us did NOT get medical training.

So a central clearinghouse system that red flags things isn't a bad idea. Most health insurance companies do it now anyway.. why ? Because they'd rather not pay for medication issues.

There's of course a darker reason... finding people who are 'doctor shopping' to enable their abuse of prescription drugs. The more centralized data is, the easier it is for a well meaning government to abuse that data for some sort of control. So...

do you REALLY want all your medications to become a public record (because we all know governments stink at privacy and security) ?

A final aside... some patients need medications that interact. My wife takes two medications that potentially interact. She's been taking them for years. But suddenly she 'cannot' because there 'is a risk'. Automating this refusal would deny patients who depend on these interactions for survival. Coding medical procedures is always a bad idea, because there has to be an exception process that involves actual human beings.

An adequate bootstrap is a contradiction in terms.
