I still use a five year old book on CSS and a seven year old book on PHP, and they work just fine. Javascript has changed a bit since then, and newer tools like jquery evolve more rapidly, but the fundamentals change slowly enough that if someone gets a job in the field when they graduate, they should be able to keep up with changes throughout their career. This will be especially true if the professors teach it properly: encourage independent learning and discovery through projects and reading and not relying solely on lectures. In other words, teach the students how to learn web development, instead of just teaching web development.
I think you're being too picky in the interest of talking down to people.
Actually, I think the people that are "talking down to people" are those that give incorrect explanations of things because they think they're simpler. Pointing out the problem with the molasses analogy is not fussing about a picky little detail, it is pointing out the analogy is wrong on a very fundamental level. It paints a picture of the pre-Michelson-Morley days of a stationary ether that permeates all space and defines a preferred frame of reference. As Einstein said, you should make things as simple as possible, but no simpler.
Yes! Absolutely. Let me second that recommendation. Best explanation of the Higgs I've ever come across as well. It is rather long (about an hour), but if you at all interested in what the Higgs is really all about, it more than repays your investment in time.
This explanation and comic are very good, but it makes the same fundamental mistake that so many physicists have made in trying to explain the Higgs field. It compares the field to molasses, slowing down particles by "sticking" to them, or providing some sort of friction to slow them down to sub-light speeds. This is fundamentally incorrect as molasses, or any other frictional medium, opposes the motion of particles, slowing them down until they eventually come to rest with respect to the frictional medium (molasses in this analogy). This is not at all how the Higgs field works. It doesn't oppose the motion of particles at all. In fact, Newton's law of inertia states that a body in motion will continue in motion at the same velocity until acted upon by an external force, and this is still true even in the presence of the Higgs field. There's nothing molasses-like about it at all. In fact, as a relativistic field the Higgs field has no rest frame. Put in other words, the Higgs field has no velocity of its own, zero or otherwise. If it did, it would break a fundamental symmetry law of special relativity: namely that all inertial frames of reference are equivalent. No field that behaves anything like molasses would be consistent with that principle.
But does the flushdns actually ERASE the contents of the cache or merely delete it? (By erase, I mean overwrite with zeros or something else so snooping software can't reconstruct the original cache contents.)
I'm in Wisconsin. We don't all have 4x4 drive, tire chains are ILLEGAL,
Tire chains are illegal in Wisconsin?!?!?!!! Wouldn't that be like outlawing air conditioners in Texas or umbrellas in Seattle? What is the rationale for that?
Very few countries have double jeopardy rules that work the same way as in the U.S. In most countries, both defense and prosecution can appeal a decision. It is not at all uncommon in these countries for acquittals to be appealed and overturned. This isn't just in Europe. It works that way in Canada, too.
Not only that, but he didn't merely download the files, but republished some of the material on his own website. Even in the U.S. that can lead to big fines or lawsuits for copyright infringement. Had he merely kept the files to himself, he probably wouldn't be in any trouble at all.
Note, the Finnish police asked for clarification and if Wikipedia answers it will not accept payments from Finnish citizens then there is no problem. If they want to receive payments from them, they will have to follow the Finnish laws. Period.
How is Wikipedia supposed to determine where the payments came from? If people donate using PayPal, is their home address always given? Is there anything to stop Finnish people from opening US PayPal accounts?
1. Keep Calm, don't panic.
2. Accelerate Slowly
3. Decelerate Slowly
4. Drive Slowly
5. Double or Triple your distance that you normally are between you and the car in font of you, to allow more time to stop.
Ummm, none of these tips help you if you're boxed in on all four sides by cars that have been abandoned by their drivers.
This wasn't black ice. It was a solid sheet of ice, curb to curb, sitting on every paved surface in the area.
The phrase "black ice" refers not to a special type of ice, but generally to ice that is invisible on the road at night time, catching drivers by surprise. It is no different than the "solid sheet of ice" that you describe. Ice is ice. Although it isn't much fun, I have driven on ice, that hadn't yet been salted or gravelled, and it is treacherous, but by driving slowly and understanding how to control your vehicle, it can be done. People in Canada and the northern states do it all the time. I won't say I've never seen cars in ditches here in Canada during such conditions, but I've never seen the kind of 24 hour traffic jams that occurred in Atlanta.
Wait, so your solution to young managers not having experience is to delay them getting experience until they're older? How does that solve anything apart from pissing on young people?
I think he said that young people shouldn't be put in management positions. They can work other positions in a company, particularly in groups where they can develop people skills, and by working for a manager, observe what works and what doesn't. An aspiring manager could meet with an actual manager in the company and ask questions like "Why don't you check employee's Facebook pages? I heard in school that it can really help." And the actual manager can reply "We've found that in the real world, Facebook profiles don't correlate with worker performance." Then when they actually do get a management position, they will have benefited from their own experience working with others, and from the managers' experience as a manager.
The article says it was the first ever action-adventure game on a console. Also full of other innovations.
Best. Game. Ever.
Including the first ever Easter Egg that I'd heard of, probably the first Easter Egg in any console game. To this day, I still remember the name Warren Robinett.
Norton Internet Security received the strongest protection rating in DTL's tests, detecting 99% of the malware used
I call bullshit. This seems like a paid advertisement to me. The only reason they used a few undetected ones was because no one would believe anything hit 100%
I can't help but think that if this really were something sponsored by Norton that they wouldn't have had a free product (Avast) score so closely to Norton (which is a paid product.)
Wasn't Win95 the first one to actually incorporate the whole OS instead of riding on top of DOS? Or was that Win98?
Win95 was also the first to incorporate Internet capability (a TCP/IP stack) in the operating system, which by 1995 was a very big deal. On Windows 3.1, you had to use third party software (such as Trumpet Winsock) if you wanted to get onto the Internet in a meaningful way (such as running a web browser.)
In the U.S. the "right" actually proposes reducing government power
Like when they impose laws requiring [completely irrelevant] vaginal ultrasounds prior to aborts, or outlawing sodomy? Or when they act in order to increase military spending?
Although I disagree with the parent, I think he/she was modded down unfairly, as some valid points are raised. The problem is, in America, there are two right wings: the libertarian wing and the social conservative wing. They agree on some issues and disagree a great deal on others. It is the libertarian wing that favors smaller, less powerful federal government, and the social conservative wing that favors restrictions on abortions, restrictions on gay rights, etc. Their positions on those types of issues are often opposed. So, in America at least, it isn't so simple as a right vs left or liberal vs conservative split.
Doesn't the FCC regulate the frequencies used by cell phone towers? Do state police have the authority to use them as well? Do they have a special license from the FCC?
There's more about it here. This recent work basically suggests that the theory might be true. It is a doubly useful theory in that it allows certain difficult problems in string theory to be solved in the language of conformal field theories and vice versa. If nothing else, it means string theory can be used as a computational tool in certain problems of condensed matter physics even if string theory doesn't pan out as a theory for quantum gravity. But it also makes string theory more likely as a theory for quantum gravity as it makes it in some sense compatible with the holographic principle, which among other things provides a solution to the information paradox of black holes.
One thing I was unable to ascertain from the article was whether Elsevier was going after authors who share the preprint version of their paper, or the one that is typeset by Elsevier. I have published in Elsevier journals before, and I send the preprint to arxiv.org where it will be permanently available for free. Then, after they accept it for publication, they send a PDF of the article typeset as it will appear in the journal, which is the same content, but laid out more professionally. When signing over the copyright, I signed a non-exclusive right to Elsevier, meaning I retained the right to distribute the preprint version of the paper. (This is required as the research was funded by the U.S. government.) I do not have the right, however, to publicly redistribute the Elsevier version of the paper. (Although I don't think they mind my sharing it privately with colleagues).
Unfortunately, it's not that simple. In the scenario you're describing, there is hidden information inside the envelopes, as the direction of the cards has already been determined. The quantum mechanical analog is this is so-called "hidden variables", aspects of the state of a system that we simply can't see. But experiments have ruled out this possibility, so quantum mechanics is actually much weirder than that.
