But the real problems are still caused by moron employees who double click on an attachment they got via email. Just happened again last week. The problem isn't people who don't adhere to policies, it's employees who don't have a clue.
And what's wrong with reading Slashdot while you're slacking off with a coffee for a couple of minutes? I'd consider an employer a slave driver if they have a problem with that.

They are truly random access devices, so you can use throughput/blocksize to get IO/s. Of course write IO/s and read IO/s are very different. I don't see the point about OLTP. Normally you don't write a whole lot of data and since the access time is virtually zero, for random writes they might still be superior to disk drives. Together with write caching that should make them very suitable for this kind of application - as opposed to streaming IO.
If you grow up being told to believe in things that aren't provable rationally, you won't develop critical thinking.
As a result, you'll be apt to believe in what you're told or what others believe too - no matter if it's in the Bible or on TV. Or on the Net, for that matter.
Well if you grow up believing in what you're told, what do you expect? People can be taught to believe in many things. Just ask Stalin, Hitler or Pol Pot.
Growing up in a religious environment seems to prevent rational thinking in many people.
The average American consumer is very much behind the average consumer in Japan or Europe. Just look at cars, TVs, household appliances, household/consumer tech in general, like phones etc. The technological advantage in the US is where decades of DoD funding created spinoffs like the semiconductor industry.
On the other hand, why *should* we evolve for IT security? It's not like there's a Darwin Award waiting for the dumbest user or admin. There's no evolutionary advantage for comp sec aware folks... unless we start creating some, like opening up safety related systems to the wild. Mmmm, how about wireless interfaces to the internal networks of cars, or to household appliances like gas stoves? Or the charge circuitry of Li-Ion batteries? That'll teach the noobs.
Transfer rate is limited by the bandwidth of the electronics (preamps and channel.) After all, you have to pick up microvolts, amplify them to usable amplitudes with low noise, and then do A/D sampling and some fairly complex filtering on them. Today's drives transfer at around a Gb/s; that is not going to increase much. Nobody will want to pay for or cool GaAs read channels. And there's no reason to expect that seek times can be reduced much. Latency could be reduced further in exchange for higher power consumption and lower density.
More than one head is a non-starter. Has been tried and the cost/benefit ratio is awful. Run two drives in RAID 0 if you need higher throughput.
That won't help. Most hard drives fail catastrophically when they fail. If you have just a few sectors going bad, SMART will tell you before you actually try to read the data if you have background scanning turned on.
Just wait until the weekend to install the updates unless there's a really hot patch that you need on Tuesday. By then you should have seen it on Slashdot if there's any nastyness going around.
Simple rule for me: If a Windows machine BSOD's after an update and it's not easily fixed, I can only assume that MS doesn't support that hardware any more. So I'll install Linux. Works every time, 3 times so far. All IBM and Dell machines.
Don't you love how the "Windows has been updated and needs to be restarted" popup comes up in front, with keyboard focus? If you're typing something, chances are pretty good that you'll hit the wrong key (like Enter) just in time. Happened to me once (that was an Outlook popup though.)
A couple of years ago I had chronic pain in the lower joints of both thumbs. Until I read an article in Mens' Health about exactly that. Root cause is driving with your hands hanging by the thumbs off the spokes of your steering wheel. I changed my hand position while driving (gripping only the rim with the thumbs outside) and haven't had the problem since.
CTS has nothing to do with joints. It's a Repetitive Stress Injury (RSI) of the soft tissue around your wrists, especially the finger flexor tendons and the fascia and nerves there.
I never had it so I can't contribute. What I do have every now and then is Achilles tendinitis/tendinosis. There's an easy fix for that: Heavy weight training. I wouldn't be surprised if that applied to the wrist too.
>What I do need is to replace my 4200 rpm slug with something faster, without draining my battery.
Some time ago I replaced the 4500 rpm dog in my Latitude with a 7200 rpm Hitachi drive. Comparing the specs, the Hitachi drive used practically the same power (0.1 W more IIRC) as the older drive. That plus a memory upgrade made quite a difference. An image copy with dd worked nicely except that NTFS encrypted files weren't readable. NTFS must use the drive serial number or something in the encryption algorithm.
These days I'd seriously consider putting my OS and swapfile on a USB key and use the disk only for bulk data. Apparently you can even hack Windows to run off a USB drive.
BTW, disk drives have caught up with mainstream tape media (SDLT:600 GB, LTO:800 GB) in terms of capacity - the only advantages left are removability and price/capacity, and you need to use a whole bunch of media before the drive cost is amortized.
>For years cars have been getting heavier and heavier in the name of safety.
Which is only driven by the marketing departments of certain American car manufacturers, and, by extension, by the other manufacturers trying to compete in the US market. The safest cars are mid size to large sedans (think 5-7 class BMWs, E-S class Mercs and similar), *not* large SUVs or trucks. Mass is the overriding factor only in a head-on collision, which is a minute percentage of all accidents. In the majority of other crash scenarios, trucks and SUVs look rather bad.
Slashdot Mirror
Imagine a back door, vulnerability or leaked/cracked private key in one of those.
Given governments' competence in such matters that's just a matter of time.
Gamers are probably the only users that are more or less immune to price/performance considerations.
Blacklists=>Proxies
Traffic filters=>TOR
etc. etc.

That's how the Washington Post puts it:
More people believe in ghosts and ESP than believe in President Bush.
Nearly a third of Americans believe in ghosts.
A new Associated Press/Ipsos poll found 34% of people believe in ghosts. And 23% even claim to have seen one.
If you feel haunted -- think how President Bush must feel.

I thought it was well over 70% who believe in ghosts - at least the old bearded one in the sky.
Gaah, to be 14 again, with an Internet connection... I'd be such an expert on Tor and proxies.

Yup I do remember Leisure Suit Larry. "Get outta da way" says the fat pimp
Is anybody writing a V2 with 3D raytraced avatars yet?
>So is this like coating the series of tubes with an improved surface so that the trucks get better traction?
Nope. Just the opposite. Lube, so the bits can slide through the tubes faster.

how are they going to regulate open source, serverless P2P systems?
