In the short term it probably won't help very much - spammers will just spoof domains that don't do SPF
I would suspect that such domains will get joe-jobbed so much that they will find out exactly what SPF is and how to implement it with exponentially (function of time) increasing zeal.
How about the combination of RBLs + SPF as being a complete solution? If you think about it, RBLs are already reputation systems, but have a lot of false positives. Wouldn't SPF put a complete stop to that downside? Then you could REALLY use RBLs so it wouldn't matter how many domains a spammer registers because you block their IP. Am I missing somethig?
The six degrees of freedom in Quake was certainly one of its best features, but I think GLQuake (The OpenGL (Voodoo) version) was just as important. GLQuake was so many leaps and bounds beyond anything up to that point it truly was revolutionary. Nothing, not event Doom3, will ever match that leap again.
Tell me about it! I do too much work on my computer to keep it current. I've run Linux kernel 2.6.1-rc2 on slack 9.0 because it works fine. Maybe when the full Slack 10 comes out. Maybe. If I can get a rainy day.
Here (Atlanta) you can pay comcast more for a "business" connection. According to the agreement with that, you can run any service on any port. The point here is that Comcast can't just block all port 25 because it would block "business" accounts too. Blocking 25 on just some users is difficult (read: expensive) and thus was shot down (RTFA).
Nuclear power is awesome. It is true that no nuke power plants have been ordered since 1979, but Plant Vogtle only came online in 1987/89. Check the link: "The total net generation for both units in 1998 was 18,549,806 mwh...". That is 18.5*TERA**WATT**HOURS*. Unit 2 alone did 10.3 in 2000. Do you know how much coal/oil it would take to replace that? Neither do I, but I'll bet its a more than a few train-loads or tanker-fulls.
Israel is the only U.S. friendly country in the middle east. It is also the only democracy. Coincidence? Perhaps, but a democratic Iraq really can't be any less friendly. China is the big threat to the U.S., but china is controllable through oil. Their economy grew at over 9% last year and they have an insatiable appetite for oil. I'm sure that is one of the reasons we are in Iraq.
...no one has been able to explain them all dark matter, the SIMPLEST explanation!!
So, dark matter is just like God. It explains everything and has never been experimentally observed. Ya just gotta believe. Physics is the new religion and physicists the new priesthood. I think someone predicted this a while back.
I think I understand what you are saying. One of the following is true:
1) The Cosmological Constant is real.
2) Dark matter is real.
Both cannot exist? Either implies something that has not been experimentally observed (like God. Neat, huh?)....because there is compelling evidence for the existence of dark matter, there must be something wrong with general relativity...
Just pissin' in the wind here, but I think the parent meant a rounder earth. The earth bulges at its equator due to its spin (and also gravity from moon, sun, other planets). This makes the surface of the earth at the equator about 0.33% (x~5000) or about 13 miles farther from the earth's center than the poles. That is enough to affect your weight. Want to lose weight? Go to the equator.
The only way this probe will really teach us anything (outside of the engineering that went into its construction) is if it fails, spectacularly
Considering the price ($700 mil), I think any failure would be considered spectacular. Spectacularly bad. At least we will get some fireworks when it re-enters, no matter what.

Why don't we point out the real problem that likely caused this to happen. Energy deregulation in the first place.
I think it is more accurate to say that deregulation enabled, not caused, the problem. Certainly First Energy used deregulation to put in place much of the pieces of the problem. You just don't hear about all the well run deregulated power systems.
I would go a step further and suggest that the author is a disgruntled former ISS employee. He started working on the worm when he was fired. He may have introduced the buffer overflow himself, just in case he was fired. The timing of the announcement and worm release would be more or less incidental in that case.
If you had a router that understands HTTP (a layer 4 router, I believe (mayber 5?)), then there would be no problem blocking individual pages (or URL prefixes) on the same site. The router would need to be programmed in real time from your email scanner, so it would not be as easy to set up as simple DNS blocking, but it could be done.
I do not know if such routers exist, and if they do, I'm sure they are *very* expensive -- probably out of your budget, by AOL could afford it.
One aspect I really like about this is that it hurts the people behind the spammers. Because if you do spam-vertize your site, people will get blocked from it *EVEN IF THEY DIDN'T GET THE SPAM!* You could potentially *LOSE* business by spamming!
Obviously, this could be abused by spammers to hurt their competitors, but the upside is REALLY attractive to me. Maybe AOL could make it block sites slightly less than half the time, so that spamming for your competitor would help them, but spamming your own site is now half as effective as before -- still worth doing.
Unfortunately, it's getting the reaction to generate more energy than it consumes, is the problem.
Actually, they solved that problem in the 50's. It's controlling that reaction that is rather more difficult...
All you need is sufficient mass so that gravity will hold it together. Of course, you'd need something about a million times bigger than the earth -- about the size of the sun.
You have it *exactly backwards*, my friend. If there weren't so many people in the field, they'd be able to handle less volume, and be much more expensive. Outsourcing would have happened much faster, in greater quantities, than it has.
Well, I don't have it exactly backwards, but I can see your point. Still, the most expensive programmers are the cheapest.
To explain/support that statement, let me point you at This paper about Superprogrammers or, the much shorter Jargon File entry. It is claimed that some programmers are at least 1000% faster than the slowest. I claim a $80k/yr programmer will get more done (and is thus cheaper) than 3x $40k/yr "should have been lawyers". It reminds me of the saying "an engineer can do for a dime what any fool can do for a dollar". Compare/contrast This Microsoft site where they think "good tools and processes" will level the field. I've got my doubts. Sounds like Microsoft hired a lot of those lawyers.
Why? Is programming talent scarce? It seems to me that it's not. Not even hardly; leaving code monkeys out of it, good programmers are 99 cents a pound.
That is because you have never met a good programmer, so you think all those average programmers you've me are good. Compared to code monkeys, they are, but that is the limit of your experience, apparently.
This is all due to the dot.com boom which brought *TONS* of people into programming that should never have come into the field. The boom was the worst thing for everyone who loves the field. All those talent-less people have given "programmer" a bad name due to the extreme practices it takes to make them productive (Think UML here).
I think you can even blame a lot of the out-sourcing to India on the boom, or, rather, the idiots it attracted.

Won't it be closer when its orbit finally decays to 0?

What if software bugs emit gravitons?
If that were true, there would be a black hole located at Redmond, Washington.

They both kind of explain each other, no?

I believe they froze Walt. So he is wretching in his ice-chest.

What is the deal with all those diffraction spikes? I don't think any of them are foreground Milky Way stars. Would they be QSOs (Quasars)?
