I think they strongly suspect it, they don't know.
It's not rocket science to figure out how a new worm works. They know that they fake the senders.
Someone might actually send the virus to someone else an email asking "What is this file you sent me".
That's not the same as a message sent by the worm, and should not be detected as such. The software should not just look at the attachment, but at the whole email. The real worm email would not include that question.
For me silent failure is broken.
For me, getting hundreds or thousands of these bounce messages every time there's a new worm is broken. Why am I paying for the sins of Windows users? And now, if mail I send someone actually does bounce, I'll never notice it because I'll delete it with all the other "bounce" messages. How's that for broken?
I have many times sent someone an email that they needed, only to find out it isn't getting through due to any of a multitude of reasons.
And... were those emails worms? No? Then what's your point? Of course you should get a bounce message if legitimate email bounces. And if you weren't getting all those worm bounces at the same time, you'd even notice the real bounce!
If a suspect message is found it should notify the sender.
That's all well and good, but in the case of these Windows worms, the person listed in the headers is not the sender. Furthermore, the antivirus companies know that they're bouncing it to someone who is not the sender. They don't care, because it's advertising their product.
Blue of course! The night sky is the same color as the day.
Only if the moon is up (since moonlight has about the same spectrum as sunlight). In the absence of the moon, the night sky is red. The light comes from molecular emission from the atmosphere. Scattering of blue doesn't come into play if you don't have a source of blue light (e.g. the sun or moon).
Here is a night-sky spectrum at Kitt Peak. Note the OH emission in the red. Also important is sodium light pollution ("Na D" and "HPS") even well outside the nearest city.
When I was an undergrad at Penn State, Moses Chan was one of my favorite professors. In addition to his obvious brilliance, he was a friendly and animated guy.
On the first day of therodynamics, he looked around and noticed that there were no women enrolled in the class. He announced: "I see there are only men here. Good. That means I can swear a lot."
He once assigned a difficult problem set over a holiday weekend. The physics wasn't that hard, but one of the problems required some terrible algebraic manipulation. At the start of the lecture when the assignment was due, some students approached him to ask for more time. Before they could explain the problem, he granted the extension, complaining "I spend my whole fucking weekend on this goddamn fucking algebra!" (He wasn't kidding when he said he'd swear a lot...)
A couple of semesters later, we saw him in the elevator and asked how things were going. He said that a student filed a "fucking complaint" because of his language. He asked us, "Do you think I fucking swear a lot in class?"
Another day, a friend of mine, "A", was wearing a sweatshirt with a football player on it. Moses talked to him after class:
M: You play football?
A: I was a linebacker in high school.
M: You suffer... brain damage?
A: You grade my problem sets... what do you think?
Another time, we were in the basement of the physics building, in a lab for another class. Moses found us, and enlisted our help: The safety inspectors were in the building, and we needed to remove his ping-pong table from the stairwell before they found it.
Finally, a few choice quotes from his lectures:
"You are not truly relaxed until you are dead."
"He was a consummated theorist."
"We call the partition function 'Z' because Boltzmann spoke German."
I'm a Penn State alumnus, and am glad to see that you (eventually) got reasonable answers to your question.
Now, here's a related one: A friend who recently took a job at Cambridge came back to the US with a packet of "Penn State" brand pretzels, which are apparently popular in England. Can anyone explain why they are so named, and whether it's got anything to do with the university? The pretzel company's web page was not helpful in settling the matter.
Yours is the second comment I've seen that implies that the article refers to book-reading as a social activity. It does not. It lists three different ways of spending time (watching TV, reading books, engaging in social activities).
If it said that Internet users eat fewer beans, sleep later, and mow the lawn more often, would people think it was saying that sleeping was a kind of lawn-mowing? I don't see what's so confusing about the sentence.
When I tried Elements (while using a scanner on a Windows machine with PE), it lacked a "Curves" tool as far as I could tell. That's an unacceptable omission in my book. Hell, even "xv" has Curves!
Continue producing the high-end cameras for the serious photographer - the same photographers that help Kodak become the Kodak they are today!
Kodak does not produce high-end cameras for serious photographers. They are a film company that (in recent times) only dabbles in cameras. Their main approach seems to be to invent smaller, crappier film formats (110, Disc, APS) and sell small, crappy cameras to use them.
From the point of view of pure science, perhaps not. But from the point of view of a US citizen it would be preferable that that $1 billion of high-tech spending occur in North America. Sorry for being greedy and self-serving;-(
Realistically, most of the money will be spent on design and engineering, and on the production of components. Most of this is likely to be done by US companies. Even things like domes are constructed in the US and shipped to the observatory site. Instrumentation, mirrors, filters, etc. are all likely built in the US (or Europe for a European telescope, etc.).
Local construction firms may be hired for excavation, pouring the foundation, assembing the dome, and so forth. But the big money goes toward the technology, which (in general) does not come from Chile.
Mauna Kea, on the big island of Hawai'i, is the home of the Keck Observatory and other large telescopes, and remains an excellent site. There are political issues with the native people of Hawai'i, however.
There is no particular reason that observatories need to be located in the US or Canada. (In fact, Canada would be terrible on the basis of its latitude alone; at the equator, every part of the sky is visible at certain times of the year. At the poles, half of the sky is never visible. Thus it is advantageous to build near the equator.)
Mauna Kea and Chile are the two most popular sites for large telescopes these days, regardless of what countries are building them. They have good weather (lots of cloudless nights), good seeing (little atmospheric turbulence, probably due to being on the first mountain range after the Pacific), and are high and dry (less opacity to near-UV and IR).
My girlfriend lives near China Lake NAWS, and I drive past Edwards AFB to get there. I've seen the F-22 in flight several times along the way. Once, they looked to be testing low-speed, low-altitude flight in some of the hilly terrain.
Never had so much trouble keeping my eyes on the road.

Piling together a bunch of gold particles does get you a bigger chunk of gold.
I bet these moderators are shocked and offended by a Jay Leno monologue.
Given that it's solar-powered, I don't think that sending it farther from the sun would work out too well.
Snopes is your friend.
