Which retail outlets will take back an opened game? Every one I've been to assumes you're a pirate, so the only option you have is exchange for another copy of the same title. That accomplishes precisely nothing.
Two thoughts to consider:
Most stores will exchange an opened box for a shrinkwrapped box if you have a receipt and complain loudly about it being defective.
Most stores will take a return without a receipt if it's not opened.
This suggests a course of action that may result in a successful return. Of course, your milage may vary. Also, this has less value if the product has greatly decreased in price since it was purchased, or if they only give you store credit and you rarely shop there.
I've worked with several RFID implementations, and all of the (silicon-based) solutions have decent encryption to prevent "capture" of IDs or other data. Usually a shared-key system -- not unbreakable, of course, but pretty difficult to intercept on the sly.
If encrypted RFID systems don't include any nonce in the request, repeated in the response, then a replay attack is possible. You don't have to break the encryption at that point, just record and retransmit.
Humans tend to repeat their mistakes, so it wouldn't surpise me if such a vulnerability showed up.
Blue, obviously, is radiation in the wavelength of around 475 nm. It is measureable. When you look up at the sky, if light is primarily coming in at wavelengths around 475nm, the sky is blue. On the other hand, if it is sunrise or sunset, or the end of the world or something, and the wavelength is much longer -- around 650 nm -- the sky is red.
What I've always wondered is whether what everyone else perceives "blue" or any other color is exactly the same.
Is my internal "image" of the color "blue", for instance, similar to the internal "image" that other people have for that color? My favorite color is blue, someone else's might be red; might not we all like the same "color", it just maps to different wavelengths based on differences in ocular components?
Unfortunately, saying things like that around people without philosophical (or engineering?) leanings typically engenders the blank "WTF?" stare.
deitel99: The machines aren't as slow as the top post says... they don't run at 20MHz, they are "capable of carrying out about 20 million instructions per second". Depending on the complexity of the instructions, the processor actually runs several times faster than 20MHz.
danheskett: That's an excellent point. A lot of people are thinking instruction = 1 cycle. The real world is that it's not unusual for an instruction to take 2, 4, 10, or even 100 cycles. The reality of the matter is that instructions can be anything from a single two bit sum to a floating point division. I see this mistake a lot...
You both assume that the one who wrote the article didn't make the same mistake in the opposite direction.
In this article about the Stardust probe, the RAD6000 is said to be "a radiation-hardened version of the PowerPC chip used on some models of Macintosh computers" which "can be switched between clock speeds of 5, 10 or 20 MHz".
No. It's just that you know you're in trouble when people use "age of the universe" as a unit of measurement. It'll break, it's just that it'll take so long that when you (or rather your far distant descendants) crack it, there probably won't be a great deal of point in knowing it.
At that point, it's simpler to use the Caveman attack:
Walk over, beat subject about the cranium with a stout cudgel, and take the subject's computer containing the keys.
The standard encryption level for online banking or purchases these days uses something called a secure socket layer, or SSL, which typically provides privacy between computer connections at 128 bits, an acceptable level. [...]
A much smaller 224-bit ECC key offers the same level of encryption as 2048-bit key in the competing RSA format. In other words, a company would need 16 times stronger encryption to get the same level of protection that Certicom offers in the ECC format.
This is comparing an apple and an orange and concluding something about a strawberry.
When it comes to encryption keys, it's not the size, it's how you use it.
And what's the guarantee? Free week's worth of ads every time someone hits your page with lynx? This guarantee business is baloney from so many points of view.
This type of guarantee is clearly more of a threat than a promise.
I have never seen a compelling argument that economic benefit was the only valid reason to do something. Do you have a hobby, or any goals other than "make money"? Getting money is only a means to whatever end you ultimately want - so many successful people seem to forget that.
Only because "successful people" are usually measured by how much money and power they acquire.
I hope to hell they're fishing for non-bouncing addresses, because at the moment any email which SpamAssassin says is spam, I bounce.
Don't ever do that, all spam has forged headers. You're just making life hard on someone who had their address sold.
Depends on whether "bounce" is being used (arguably misused) to mean rejecting the email during the SMTP transaction. That won't directly cause misdirected non-delivery notification.
Crafting such a notification after accepting the message and delivering that to the envelope sender is indeed very rude these days.
Did you read the law? It does not say it's OK to spam. It bans the vast majority of spam and prescribes harsh penalties.
Read it again. It doesn't actually ban spam! It bans many of the bad behaviors normally exhibited by spammers trying to hide themselves, blame others, and steal services, but doesn't actually prohibit spam itself.
...what happens to quite a lot of Pacific islands in John Barnes' Mother of Storms.
Relating to another thread, if global warming is a reality, regardless whether humans have caused it, we may be seeing much more of this kind of thing.

It's nice, but it costs $1200 on sale and is a tempting target for thieves. Gimme one where the expensive bits are in the trunk any day.
What these need is a retracting cover that looks indistinguishable from an old mid-1980's Realistic(tm) AM/FM tape deck.

In the USA, we also have parties that call other parties communists.

"Boob tube tracks boob" What a scoop!
Which, the one on the couch or the one on Ms. Jackson's chest?
True, but you'll be able to modify and/or upgrade it any way you want, whenever you want, without worrying about the warranty (since there is none)...
Once one voids the warranty by opening the unit, the issue of worrying about the warranty is neatly resolved.
I mean the entire category of slack-jawed viewing without a keyboard.
A remote control is really just a wireless keyboard.

"All But Degree"? Does that mean "I don't really have the degree, but I worked towards it at one point"?
I have never seen a compelling argument that economic benefit was the only valid reason to do something. Do you have a hobby, or any goals other than "make money"? Getting money is only a means to whatever end you ultimately want - so many successful people seem to forget that.
Only because "successful people" are usually measured by how much money and power they acquire.

And IIRC, every administration except for 1 (maybe 2) has run a deficit and the country has not yet fallen.
They make up for it in volume?

As it says, you indeed CAN-SPAM.
There is water on Mars. The ICE CAPS were first noticed about FOUR HUNDRED YEARS AGO.
332 years ago, to be specific, though looking through a low-powered telescope isn't quite the same as using an orbiting thermal emission spectrometer.
...which will suddenly have become much more expensive.
If they're going after 800lb gorillas...
Well, yeah, they have the most bananas to take.
At any rate, Niueans don't shy away from selling the .nu domain (means nude in French), and host many adult web sites under it.
Well, not exactly.

...it would be more likely that the public would realize that they're just filming this whole shebang out in the Utah desert.
Maybe, but this suggests that SCO would be out in force, battering the rover with blunt weapons.
Exercise: Take any small scale closed system, like the Biosphere project a few years back.
Pump in lots and lots of C02, as indeed did happen in Biosphere since they underestimated just how much the humans would respirate within.
Result: Bigger greener faster reproducing plants, and pretty much stable C02 levels.
Now clear-cut them all for building space and materials.
