I was a bit hyperbolic, but I didn't really assume anything. I just chose those numbers because they're more representative of the average person. So you're 20/10 -- if you buy a 36" screen and sit 10 feet away (a perfectly reasonable size and distance for TV viewing), you can't tell the difference between 720p and 1080p. I'm 20/15 (when I wear my glasses), and I have a projector in my living room that displays a picture about 84" across, but I sit a good 15-20 feet away from it. You'd have a hard time noticing any difference between the two formats. I certainly don't think it's worth more than doubling the bitrate just so.1% (or whatever) of people can kinda see a difference. The vast majority of people are 20/20 or worse even with corrective lenses.
Note that NBC and some other stations broadcast in 1080i, which is an entirely different matter. 1080i and 720p use about the same bandwidth at the same bits per pixel (1080i is about 10% more).
I hypothesize that most people browse Slashdot at work, where they don't necessarily have complete control over their browser choice. I use Opera almost exclusively at home, but I'm stuck using IE6 at work.
First off, you don't need to have the user actually click submit. You can submit forms with Javascript or even just use XMLHTTPRequest. Secondly, checking referrers is pointless. It's easy to lie about them.
That doesn't protect you. Sure, it prevents the img tag vector, but it doesn't stop an attacker from convincing users to submit an arbitrary form.
Send a pseudorandom token with every form
As far as I can tell, that's the only solution that doesn't rely on Javascript shenanigans, but it doesn't really stop it. All it does is reduce the problem to a cryptographic attack -- which is subject to brute force.
That's exactly my point. My entire family flew round-trip from Frankfurt to Barcelona for less than $68. I flew round trip from Frankfurt to London for less than $5 (it was $45 once you added in airport fees).
Unfortunately, we don't have anything like that in the US. Our budget airlines are about half the price of the major ones. It's unheard of to buy tickets here for a couple bucks like you can on Ryanair.
It's not a Fedora vs Red Hat thing; it's a 5.8 vs 5.10 thing. Apparently, there are different package maintainers for the different versions, and the 5.10 guys are much better about working with the upstream.
They say failure rates are "in the teens percent". Figure 20%, just for kicks. That means your chances of either card failing is 1 - (1 -.2)(1 -.2) = 36%.
For some reason that I don't understand, the vast majority of people have innate misconceptions of the rules of probability.
You may not have noticed, but a computer does not "work" without software. That's why it's perfectly reasonable for consumers to expect software to come loaded on their new computer. When you buy a cellular phone, do you expect it to come with empty memory so you have to install the communications software on it before you can make a call?
If I buy a cell phone, it does absolutely nothing at all until I purchase a subscription to a cellular network.
My wife and I maintain separate logins on separate X sessions, and we switch between them. It's like your first case, except that neither of us logs out.
You can do the same thing on other OSes, where it's usually called "fast user switching".
My wife and I share a computer. She uses mostly uses Firefox, I mostly use Opera. This is on a 64-bit Ubuntu Hardy.
I have noticed no difference in her memory usage since we upgraded to FF3. I used to regularly have to kill her browser every once in a while (maybe once or twice a week) because it was eating up all the RAM. Since we upgraded to FF3, I can see no difference in memory usage.
For example, right now FF is using 300MB resident, Opera is using 100MB. Flashblock is installed on both browsers. Granted, that's not a terribly good test considering we've been browsing to different sites, but I've found that those numbers are fairly stable. FF usually levels off in the 300-500MB range, and Opera in the 100-150 range.
It's possible that if your distribution of GPL software is entirely non-commercial, your lawyers thought provision C applied to you. That provision is explicitly left unavailable to commercial distributors.
Kostenlos seemed to me to be the universal word for "cost-free" in Germany, but I suppose there could be regional differences. I was in the Pfalz.
I'd argue that "frei" doesn't usually mean "freedom" either. For example, the German "no parking" and "no stopping" street signs read "parking frei" and "stoppen frei", respectively, where "frei" means the exact opposite of "freedom".
Errr, re-read the article there, the sample never WAS E. coli. E coli was the food source for the bacteria Errr, re-read the article yourself.
"Twenty years ago, evolutionary biologist Richard Lenski of Michigan State University in East Lansing, US, took a single Escherichia coli bacterium and used its descendants to found 12 laboratory populations."
I'm not really sure how you misread the article so completely.
Micro-evolution refers to the honing of traits within a species. Macro-evolution (which had here-to-fore been unobserved) refers to the divergance of separate species from a common ancestor.
And that's just what happened. A defining characteristic of the E. coli species is its inability to metabolize citric acid. After tens of thousands of generations, one of the samples can. So that sample is no longer E. coli.
People have been "geting arrested, beaten, shot, hanged, [and] beheaded" for their religion throughout history, yet we know that religious affiliation is not immutable.

No, it doesn't.
AFAIK, HD OTA broadcasts in the US use MPEG-2. I don't think that qualifies as "VERY compressed".
Unless you're sitting less than ten feet away from a six-foot-wide screen, you can't tell the difference between 1080p and 720p. All you're doing is wasting money and energy.

Is one of my users going to click a CSRF-exploit link 4 billion times in a row[...]?
Of course not. But a Javascript snippet on a site they were tricked into visiting might.
First off, you don't need to have the user actually click submit. You can submit forms with Javascript or even just use XMLHTTPRequest.
Secondly, checking referrers is pointless. It's easy to lie about them.
Don't allow GET requests to modify anything

Huh? Snopes *confirms* the Coke-tadpole story; they only debunk the hyperbole.

YMMV.

No one was "waving a gun around". The article doesn't even imply that anyone was even *holding* the gun.
If farmers "always keep [guns] out of sight" in your country, what's the point in them having a gun? Surely, it must be visible at least occasionally.

And that has to do with gayness being immutable... how?
But by all means, don't let me detract from your fundamentalist views.

In short: this is macro-evolution.
