Spammers simply proxy the CAPTCHA images, and re-present them on their own sites. Users of their sites then process the CAPTCHA for them, and they turn around and use the user's input to register on the original site.
For example, say compuporn.com wants free geocities accounts. compuporn.com offers free memberships on their site; when Joe Sixpack loads the signup page, compuporn.com runs a script that starts a new registration at geocities.com, and copies the geocities CAPTCA image, presenting it to Joe Sixpack at compuporn.com. Joe Sixpack puts the correct string in for the CAPTCHA, compuporn.com takes Joe's string, and uses it at geocities.com.
Viola. Compuporn.com has a new geocities account, without any OCR, and without any employees of Compuporn.com interpereting the CAPTCHA by hand.
At work we backup our managed server (served by pair.com) with another online backup service.
We've got under a gig of data at the moment, but it's worth a lot -- especially our 40,000 lines of proprietary PHP, and our customers' data, consisting of a few million database rows.
Of course, size doesn't matter much because pair.com naturally has a fat pipe (OC-something or other, I'm sure) so our server-server transfer rate is great, reguardless -- the crappy throughput of our office DSL doesn't come into the picture at all.
So, "cookies are necessary" my hiney. I don't buy that...
Cookies are really the only reliable way to identify a client. Did you type your username and password in to post?
No. Because you have a slashdot cookie identifying you as user 209368.
Now, if you wanted to enter your user name and password every time you did anything on any website ever, then yes, you could hapily browse the net cookie-less.
Good luck logging in to you bank website, buying that book on black helecopters, or selling your tinfoil hat collection on Ebay, though.
They've got a terrible track record with big bugs, and cleanup afterward.
Diablo 1 was probably one of the most hacked/exploited games of all time. AFAIK all of the *craft games have had maphacks. Those caught using them in WC3 were banned - in the *thousands*. Diablo 2 saw more dupe bugs, and thousands more bans.
I don't doubt we'll see thousands more bans in the wake of this fiasco.
Turbine, the developers of the relatively unknown "Asheron's Call" MMO had a bug policy I could deal with - They figured, 'Hey, we left the bug in, our bad. We can't hold you responsible for our mistakes'. They of course made an exception for any behavior that disrupted other players play, i.e.: crashing the server.
Rather than take responsibility and making fundemental design changes (maphacks should be impossible - the client shouldn't have full map data!) to make their games secure, Blizzard seems to prefer the 'Ban them all' solution. That's a rediculous way to treat tens of thousands of paying customers.
Yahoo does the same thing. Although my interview was far more code-based, and far less conceptual.
There was one question about finding a poisoned bottle of wine, though.
It's industry standard.
There are few if any cases where your (0 == "eggs" != "spam" == 0) case comes into play in the field. And for the cases where it might, we have the type-safe === and !== operators. Yes, it seems quirky to a programmer coming from a strongly typed language, but once you adjust, it's not a problem at all.
It works by enhancing muscle movements. You move a muscle a little, the exoskeleton translates that into a much larger movement.
Handicapped people (paras, quads) do not have muscle control in their handicapped limbs, so this exoskeleton can't help them.
FTA:
The 15-kilogram (33-pound) battery-powered suit, code-named HAL-5, detects muscle movements through electrical-signal flows on the skin surface and then amplifies them. It can also move on its own accord, enabling it to help elderly or handicapped people walk, developers said.
A look at the article reveals that the main components in this invention are a centrifuge to adjust pressure, and a battery to power said centrifuge. Both of these components have been around in usable form for decades at least.
Batteries have been around for decades, yes, but it's likely that batteries with acceptable power densities have not.
Battery technology has continued to develop over the last few decades, for cell phones and laptops
Compatibilty was actually pretty poor in windows 2000. As such, every box I have has both windows 98 and 2k installed. Anything 2k won't run, 98 will.

Isn't this a hormone supposedly released during the female orgasm? Google brings up a couple sites calling it "the touch hormone", released by physical contact, as well as orgasm.
The first is that this can probably be exploited by malware/spyware to make "invisible" interfaces that sit over top of existing applications, happily monitoring everything you're doing.
Processes running in the background can already do this. Consider: key loggers, BackOrifice, PCAnywhere...
You don't need transparency to have programs that run with no visible UI.
The previous article's comments included a completely erroneous post re: OS limitations on drive capacity, modded 5, informitive. The current OS based hurdle is 28-bit LBA. This means a maximum of 2^28 (27?) 512 byte sectors, for a total of 137 gig of addressable drive space.
48-Bit LBA went mainstream somewhere around '02, so on older hardware it's a crapshoot. The only windows versions that support it are XP and 2K with a service pack, and then only after adding a special key to the registry.
48-bit LBA should support up to about 137,000 TB, if my math is any good.

Your CAPTCHA is not immune to this attack either.

Satelite comes with terrible round trip times, though. I hope you like pings of in the 1000ms range ;)
(The trip out to orbit is around 400ms, and it's a good 400ms back)
Andre was about three times to large in every dimension to be a Neanderthal. Homo Sapiens are much taller than their prehistoric cousins.
RAID 5.
Stripe checksum data across all 5/10 fingers, for when you lose some.
Touché.
A better example is:
char i=0;
while(i 256) i++;
You have an infinite loop because i rolls over when i=255 and you execute i++;
== isn't broken, it's ambiguous and complex. It's also well defined and documented:

So you trust people who touch you. Interesting.
In my experience, barcode readers don't work well on displays. The white:black ratios and reflectivity are all wrong.
Any reason you couldn't just underclock? ;)
I'm sure if we were using IPv6 right now, it wouldn't be hard at all to get the list of assigned subnets.
In other news... crackers have obsessively moved to Germany, and signed up for accounts with dynamic IP addresses.
Obsessively? You'd think moving to Germany once would be enough.
I'm so confused. Usually all I hear about is underpaid teachers. Now, you come along and tell me teachers are grossly overpaid?
I just don't know who to believe anymore!
Retail space is expensive. A big warehouse in the middle of nowhere and some bulk, presorted postage is cheap.

That's only if you don't count the cost of the ensuing loss of consumer confidence.
Something bad management frequently neglects.
