While an object in motion tends to stay in motion - it only does so until subjected to an opposing force. In this case, that opposing force is Earth's gravity, and all a "little propellant" buys you is a slightly higher orbit.
Gravity will not bring it down, not for millions of years. Collisions with molecules in the fringes of the atmosphere are the opposing force.
Let me first say that I've read TFA but not the original paper. The following criticism is based on a presentation I attended long ago on another proposed mechanism to explain periodic extinctions.
When you look for a periodicity in a bunch of data, you might do a fourier transform and look for peaks. (The other work did that.) Essentially you're doing a large number of correlations. If you try 100 corelations, you should not be surprised to see one that's significant at the 99% level, just by chance!
On the other hand, if the periodicity they found matched known astronomical phenomena (as opposed to the other work I looked at), the probability of a chance result is much reduced.
To stick strictly to the question (although I suppose there's no reason we should), that question is "Were the parents negligent in not preventing the students from doing what they did?"
I believe every digital crime has a physical-space analog, and here it would be slander or libel through some more traditional medium. No parent can be expected to supervise every hour of a teenager's access to paper, paint, or typwriters. If I were a juror, I would not find it a reasonable expectation that a parent be aware of everything done on a computer either.
No offense man, but what a waste. Wish I had a nickel for everyone who kicked themselves later in life for the fun they didn't have when they had the chance.
Actually, if I had it to do over again I would opt for about 25% less fun and a bit more focus on the work. Not that things turned out badly; I graduated with honors and a double major. It just seems so inefficient in retrospect. Much better qualities of fun are available once one has the long green rolling in.
with XP PRofessional you can usually make things work by allowing either the users group or a particular user to write to the application directory
I did that with CACLS. It got me to a state where if an admin ran the game once, then non-admin users could run the game successfully until the next reboot, after which an admin had to run it once again.
Take contorl of their PCs and reduce their user rights. In truth, IM as very difficult to monitor reliably. There are ways to defeat most logging facilities.
There are many popular games for kids that won't work from a non-admin account on XP! I was shocked. And dismayed. The list begins with The Sims and goes on and on.
Yes, I tried setting ACLs with the cacl command, but it didn't solve the problem.
When my town put municipal fiber to the home on the ballot (twice, the second time with no risk to taxpayers whatsoever), both Comcast and Ameritech flooded the city with color glossy scare-pamphlets that were packed with lies. They also told their employees there would be hughe layoffs if the measure passed. The measure was defeated, and of course layoffs followed anyway.
The Big Bang was the Big Mistake because more matter survived than anti-matter to form the universe instead of returning to the void.
The "initial" (whatever that turns out to mean) mixture mat have been perfectly equal. But departure from thermal equilibrium due to the expansion, combined with asymmetric rates for reactions involving matter vs. antimatter, lead to a small imbalance.
It is not the case that health care is responsible for all new jobs since 2001 and other industries added none.
What is the case is that there are a number of ways you can partitiion all employment areas into two sets, such that the net job increase of one set is zero. One of those ways is to let one set be all areas of health care and the other set be everything else. When you do this, you're cancelling out other high-job-growth fields with shrinking fields, and making health care stand out like a gangrenous thumb.
The increase in the health care sector is extraordinary, yes. But to portray the facts the way TFA does is just deceptive.
They also contain alot of stuff that's plain wrong. For instance, Windows runs fine out of the box, there's virtually no advanced configuration after you've installed it.
Having just set up two brand new machines with XP Home pre-loaded, I can tell you that one of us is hallucinating. Getting through the first round of Windows critical updates and A/V updates was incredibly difficult. And I didn't just fall off any turnip truck, either; I've been at this since the PC/XT, the Apple II, and the Z-80 development boards.
And the children have to be "admin" users in order to play most of their games? Come on, now!
I think I missed the part of the oath of office that said what took precedence over upholding and defending the constitution. Could you fill me in on that?
more secure alternatives like *nix and MacOS, which have a chance of actually fixing the underlying problem.
How so? When replying, please consider that I'm Joe Sixpack, armed with the root password, just enough smarts to install stuff and not enough smarts to not install bad stuff.
I put it this way: Windows' application integration is built on a base of executing as instructions anything it finds which can possibly be executed. Documents and help files have embedded controls to be executed by the system, to name just one example. MS has learned that this is dangerous behavior, but their ability to move away from this model is severely hampered by the need to maintain compatibility, even basic functionality, with a mountain of installed base.
Intriguing parallel from fiction: Vernor Vinge's "A Deepness in the Sky." There are long-term plots in there that make the Harkonnens and Atreides look pretty superficial.
And Vinge knows computing and the internet. He was here before you were, no matter how low your slashdot id is.
The real reason you don't see that many viruses or worms directed at linux systems is that the concept of least privilege was implemented at the start.
No it wasn't. And it still hasn't been.
Certainly it has a concept of "less than full privilege," and that was there from the start, having been copied from earlier systems. Windows has this concept also, but it's perhaps more honored in the breach than the observance. However, my email client, my video player, and my web browser still run with the full privilege of my user account, when something less would be sufficient. Any protection I have from malicious content is due either to efforts within the application rather than the OS, or by my choosing a bare-bones application which is as dumb as a box of rocks.
ZDNet complains that Apple still isn't in the workplace
ZDNet must have never visited my workplace. People are pretty free to specify their own laptop models, and the percentage of Apple-branded laptops spotted in a meeting room is often 50%, and has been as high as 100%.
am always frustrated with the spinning beach ball animation while I wait for my app to launch.
My laptop is hardly better than the system of the paent's author, but there are only two apps I experience unacceptable launch-waits for: one is a java game platform that the loads dozens more jar files, and the other is Adobe Acrobat Pro, which does something similar.
Actually, in both cases, the app starts and shows itself on the screen promptly, it just isn't ready to do anything for me for a great many seconds.
This is at 1GHz, 1GB, PPC... and with the Dashboard running. But I must say, I have seen reduced VM trashing with java apps if I first send the Dashboard away by using Activity Monitor to quit (not force quit) the Dock. The Dock restarts right away, but the Dashboard widgets don't start until the next time I visit the Dashboard.

Was TFA corrupted? I didn't find the list of "influential computer scientists" in it. Just a bunch of "great programmers."
I did that with CACLS. It got me to a state where if an admin ran the game once, then non-admin users could run the game successfully until the next reboot, after which an admin had to run it once again.

The world makes a lot more sense if you assume that at least a few politicians understand things things quite well.
I put it this way: Windows' application integration is built on a base of executing as instructions anything it finds which can possibly be executed. Documents and help files have embedded controls to be executed by the system, to name just one example.

And if enough individuals agree with you, it will indeed be so.
What a beautiful world.
A whole new interpretation of the phrase "Call me, Ishmael!"
The article will teach you many varriations of "we made it up."

I know a guy in this industry. He's a supervisor of programmers. He travels quite a bit. The programmers are in Russia.
Well, duh! If you want exciting travel, you want FTL!

Is he Swedish or is he a Norwegian living in Sweden? I believe the submission is in error on a non-negligible point!
