"rootkit" is often, stupidly, used as a term for what the old school virus writers call "stealth".. intercepting api calls and falsifying the result to hide something.
they usually only do directory stealth.. the most trivial form..
although I suppose there have been a few rootkits that did full stealth.. actually hiding modifications that have been made to a file.
Full stealth comes in two forms:
* remove info to be hidden on open / replace info to be hidden on close; or * direct updates of the buffers returned from each read.
Obviously "redirection stealth", as the second form is called, is only good for files that are opened read only. It also happens to be the more efficient, and more difficult to get right form. As such, most viruses tend to only do the first.
The hardest part about using stealth in a virus is to decide when it should be turned on and when it should be turned off. Ideally, you only want to turn it off when the user is performing an operation that is part of an infection vector. For example, when they are putting exes into an archive you definitely don't want stealth active.. otherwise the virus won't get copied into the archive. But when they're running their virus scanner, you definitely want stealth to be active.
Of course, none of this is relevant to "root kits".. the stealth is always active, unless you know how to manually turn it off.
I think power storage is an interesting technology. We're so used to the power grid being always on, but that kind of reliability comes at a cost. If we all had large flywheels in our basement or water gravity towers, we could store energy to cover the temporary glitches in the grid. I heard about something the other week that I'd never really thought about before, apparently some hybrid vehicles can be used to power your home during an outage.
In regards to communications, if you drive around your neighbourhood with NetStumbler running on your laptop, you'll see there are a LOT of wireless access points these days. I remember only a few years ago talking with people who were building a wireless mesh and the idea of getting people to run a node was considered too technologically confronting.
If you want to make an argument as to why Google shouldn't be able to aquire Double Click, you have to talk about prices.. you'll just be ignored otherwise.
A year from now, every machine will be a 64 bit machine.. and come with 4 gig of ram. People are not going to buy these machines with XP preinstalled.. that would be a waste. They will want a 64 bit operating system. XP64 is a piece of shit. It makes Vista64 look like gold.
This is why Eric. S. Raymond has been saying that Linux has a year to get its shit together and get preinstalled by Dell, et al.
It's a response to your message because Kim Jong Il is the definition of bat-shit-insane.
Fact is, the only way to prevent a nation from getting "the bomb" is to infiltrate their development program and sabotage it from within over an extended period. That's exactly what Mossad is doing, so don't worry about it, ok?
Israel won't let Iran get the bomb.. at least not under their own steam. If another nation was to give Iran a bunch of premade nukes, that might be a different story.
What, you think this is Kuro5hin? No, there's still people who are paid to read submissions and decide what best "represents Slashdot".. and yeah, they never read the site themselves, so they have no idea what is on Slashdot.
Yeah, it was added because the book was so short and people were not interested in buying a pamphlet. I guess they figured it was better to put "letters from our website" instead of just blank pages. I disagree.
Thank you very much.
He entered a search term that he couldn't recall Wednesday, although he said it "wasn't a real expressive sexual kind of word." And then, he said, he got caught up in a pornado -- sexually explicit pop-up windows took over his computer.
"I had this instant flash of pornographic trash on my computer that just started popping up," Brown said. "I could not turn it off. As fast as I would turn something off, something would pop on."
He had to turn off his computer to stop it, he said.
It could happen to anyone, said Sen. Scott Jenkins, R-Plain City.
"I've never opened a site in my life, but what pops up is unbelievable," he said. Jesus, install a popup blocker (or FireFox) you luddite bastard.

Hmm.. wonder if you could flash a CD-ROM drive to run arbitary code on start-up.. presumably yes.
If they've owned your BIOS, reinstalling won't help.

I love the way people say "you need to reinstall" .. as if you're going to do better building the box to be secure this time.

So there is hope.
Sigh. They're talking to the Federal Trade Commission about a merger.. the only thing that matters is the effect the merger has on the market.
and, as such, is irrelevant bashing.

Oh, I see, you're not naive, you're delusional.
Cool. Sorry to waste your time with reason.
Talk about overestimating your own significance.

So this is why North Korea has been invaded already right? Oh wait, it hasn't. Threatening non-proliferation enforcement is just a big bluff.
He was in Iran and downloaded it, from the US, to his laptop.

Clearly, seeing as he doesn't even know the difference between moderator and, *cough*, editor.

If you're thinking of buying Freakonomics, don't bother. Half the book is "letters from our website".
It's one of those books you buy at the airport before a long trip only to discover that it only takes half the trip to read it.
Or, if your needs are so minor, use OpenBSD or something.
In time honoured Slashdot tradition, let me make a car analogy:
Hey folks, I just got a car and I'd like to know how to change out the engine and stuff, can anyone recommend a website?
I just put it down to them being cry babies.
or he was using a cracks search engine :)
Maybe he was searching for a crack :)
