Learn a little bit of self-discipline if you are a work time web junkie.
This program sounds like an ideal place to start.
Seriously. What alternative learning method do you suggest? Or is "Just learn it" the best you can do?
I suppose you also do not like the concept of drug rehabilitation centers. After all, eliminating the temptation of drugs is a cop-out, right? They should just learn some self-discipline!
If you are distracted that much that you must have a program that not only locks you out of the internet, but also locks you out of root, then you seriously need some sort of procrastinators anonymous.
And on the first day of Procrastinators Anonymous, they will probably give you a program exactly like this to aid you in developing self-discipline.
Seriously, what exactly do you think goes on at an Alcoholics Anonymous meeting? Do you think they all sit around and criticize each other for lacking self discipline? "Bill, you fucking loser, I can't believe you need help to recover from your alcoholism!"
Discipline is a learned skill. I'd say that a person who is willing to install a piece of software like this one to improve their self-discipline is already showing a great degree of it.
If discipline could simply be called up from the depths of your being at will, like a fart for example, we'd have no need for military boot camps.
Because I simply do not 'respect' anyone who stomps on freedoms.
Apparently, however, you are willing to stomp on the freedom of foreign powers to govern themselves as they see fit. Presumably, these anti-hate-speech laws were passed through the French democratic process. How can you claim to love freedom while simultaneously denouncing something that was decided through a free vote?
Insisting that all foreign nations govern themselves in a way that seems "fit" to your mind is tantamount to imperialism.
And where then, pray tell, does the energy go? it doesn't just disappear (conservation of energy)
You are profoundly ignorant.
Just because the temperature does not increase does not mean the energy disappears. The specific heat of liquid water is different than that of ice, thus the energy you believe has been "lost" is still present in the form of kinetic energy as well as electrical potential between the (polar) water molecules. Ice and liquid water simply have different potential energies at the same temperature. If they did not, how can you explain the difference between the states?
I suspect you are the same idiotic AC who lambasted me earlier. You're not as smart as you think.
then realize that the temperature of the ice/water bath does increase.
Do the experiment instead of wanking on Slashdot, and see that we are correct.
You're agreeing with the moron above who believes that he can magically make the heat from the can move backward in time (and space) into his freezers' coils just because they got warm when he made ice earlier.
Just because your avian brain doesn't grasp the concept doesn't mean it's wrong. Apparently you haven't heard of "heat of fusion." Had you taken physics beyond the sixth grade level (which you apparently believe is as complex as it gets) you would understand what's really happening here. The heat goes to the phase change between ice and water instead of causing a temperature increase. Yes, this is not an ideal scenario, and a real ice/water bath would have localized regions of increased temperature. Your point?
This is fucking slashdot, I shouldn't be reading this absolute bullshit.
I've become quite used to seeing complete bullshit on Slashdot when it comes to physics. As you have spectacularly demonstrated.
Can you please explain how aluminum is not environmentally friendly? Yes, big piles of aluminum cans are unsightly and offensive to humans, but I highly doubt that nature gives a shit.
Energy must be conserved, but nothing necessarily has to get hot, at least in the short term. If you put you can into an ice/water bath, the can will cool down, and the temperature of the ice/water bath will not change.
Right, but although the ice/water temperature is staying constant, the ice is melting, therefore the entropy is increasing.
When I first read the story it didn't occur to me that they could be using a chemical process. In that case, the heat extracted from the soda is transformed into chemical potential energy. But entropy still had to increase, back in the factory where the chemical agent was first manufactured.
For those who haven't figured out how a Thermos works... it tries as best it can to be an airtight device with walls thick enough to not let heat in orr out.
Actually, it doesn't matter too much how thick the Thermos walls are. A Thermos (or similar container) actually has a vacuum chamber in its walls which is coated with a fine silvered layer. The vacuum stops conductive heat transfer, the silvering prevents radiant heat transfer. The thickness of the vacuum layer isn't that important, merely the fact that it is there.
Yeah, your Thermos contains a reasonably good vacuum! Smashing it with a sledgehammer, for instance, would be a pretty stupid plan since it would implode quite like a CRT would.
Welcome to Oklahoma, where beer over 3.2% alcohol is only sold warm, and only in liquor stores.
Or try Oregon, where beer and wine cannot be sold between 2:30 AM and 5:00 AM (I think those are the hours). Where a liquor store cannot sell wine or beer, only liquor. Where a supermarket cannot sell liquor. Where a liquor store can only be open 35 hours per week.
I think each state has its own fucked up laws regarding alcohol. None of them make any sense.
In any cooling system, the heat removed from the stuff being cooled is more than compensated for by heat somewhere else. You know, laws of thermodynamics and all that.
So the question is, when this device activates to chill the beverage, what is it that gets hot?
Wow, you completely misunderstood me. The original point I was making was that you should not judge real researchers by the poor testing methodology used by these people. It is quite possible to perform an unbiased test and there are very specific and well-known methods to do so.
everyone has an agenda, whether it's to get published or, in this case, to get money
I can't see how wanting to get published is an "agenda." Without publications what would science consist of? People doing experiments in isolated labs, occassionally discussing the results with each other over a few beers at the pub?
Am I the only person who wonders what the hell the difference is between a Gold and a Silver if there were only 1/100 difference in the competitor's performances?
It isn't the absolute difference in times which you should look at, but the ratio of those times to the total spread.
If the fastest and slowest swimmers are seperated by only 0.1 second, then that 0.01 second difference between the top two finishers becomes very significant. It's a full tenth of the spread.
In a sport like marathon running where the spread is hours, a difference of 0.01 second is nearly meaningless.
What sort of system do you suggest for "fair judging" of a competition that boils down to a very athletic beauty contest?
This isn't meant to disparage the sport of gymnastics at all, it is clearly a very skilled sport which deserves to exist on the Olympic level, but I can't imagine any way to implement truly fair judging without reducing it to something boring and mechanical.
If you're actually using a finger tip to hit CTRL way down there, then I congratulate you on your flexibility!
I do, and it's not even difficult.
Perhaps it's because I shift my hands on the keyboard as I type instead of staying religiously on the home row. I type about 90-100 WPM despite not having a "proper" style, and I don't really find any key combination awkward unless it consists of more than three simultaneous keypresses.
*real* researchers give ther results they're paid to give, and don't give a damn about methods.
You speak with your ass. You cannot get published if your methods suck. By "researcher" I mean an actual scientist, not somebody in a corporate lab or a basement somewhere. If you think these people are in any way equivalent to real scientists who actually care about doing things the right way, then you clearly have an extremely limited experience of science.
The word 'Firewall' has a specific use in the IT world, and this aint it.
A firewall is a device which rejects or passes packets according to specific criteria. In this case, the criterion is whether the packet is part of an SMTP session which appears to contain spam-like data.
What's sad is I didn't know what keys to press; I had to go into emacs and try it once to be able to write it down.
That isn't sad, it's very normal.
I can type my password in under two seconds but I couldn't tell you what it is even if I wanted to. And, if I try to think about it as I type it, I suddenly find that I cannot type it.
This is pretty common in all areas of life. If you have something committed to muscle memory, often you'll find that trying to think about what you are doing makes it impossible to actually do it. Weird but true.
If we followed your suggestion, vi users would jump ship by the millions to use the super efficient emacs! Nooooooooooo!
I like my editors confusing and bulky. That way, when somebody looks over my shoulder as I perform a complex operation requiring 13 different keystrokes in under one second, I appear superior and godlike.
"My God man, how do you remember the key combination for that and enter it in a fraction of a second?"
"Ahh, the question you should be asking yourself is, why can't you?"
Support vector machines are very legitimate tools for text classification. Why not try punching the term into Google instead of asking stupid questions on Slashdot?
It's easy to produce these kind of results in trials - you just tune the spam filter to handle a certain set of emails, then you feed it those emails again and you get a near 100% success rate.
No real researcher would ever perform a test in such a way. We always use seperate training, testing and validation sets.
This is the kind of goof that gets your paper rejected from journals. Incorrect test procedures which introduce bias are, unfortunately, rampant among amateurs.
While it is entirely possible that this company performed their testing in a bogus way to make their stats look better, please don't generalize that to the entire community of people doing research into spam filtering and text classification in general. We're much smarter than that. Please give a little credit.
the term 'Mail Firewall' is pure marketing bullshit. It's a spam filter. Get over it.
Not necessarily. I don't know how much configuration this system requires, but if it requires nothing more than simply plugging two network cables into a box and away you go, then I think it is very appropriate to call it a "firewall." The idea of having a box which you can plug into your network and eliminate spam without worrying about setting anything up is really, really cool. But I don't think this particular product is it...
I fully agree on the uselessness of the "special keys." However...
Printscreen/SysRQ is useless (unless you are a kernel hacker and you are using it as kernel magic key).
Not really... How else do you take a screenshot in Windows?
I haven't used Pause/Breakkey since the days of DOS.
Many games use the Pause key to pause, which makes sense.
Same goes for entire numeric keyboard, but I believe it can be useful for people that need to enter a lot of numbers.
Not only that, but sometimes it can be extremely convenient to be able to type '*' and '+' without having to hold down Shift.
Remember, the numeric keypad was around before the arrow keys were invented. Most older PC users I know still insist on arrowing with the numeric keypad (with numlock turned OFF of course), and have a hard time using the arrow pad.
Oh and of course, remove the capslock key and place the control key in the proper place.
Agreed re: uselessness of caps lock, but I can't stand CTRL in that position. It's awkward for my hand to the point of cramping. There is no "proper place" for a key except wherever is most convenient for you.
Learn to use xmodmap. Or whatever the equivalent is on Windows.

Don't you think there is a huge distinction between the process to manufacture a substance, and the substance itself?
Nice assumption. Too bad it's wrong.
Puhleese. Just stick you head in a bucket of water. It will benefit us both.
Nice. When you can't rebut an opponent's point, ask him to kill himself. It makes things so much easier.

Where did the CO2 emerge from the can? How did they prevent people freeze-burning their fingers on jets of supercold CO2 gas?
Or try Oregon, where beer and wine cannot be sold between 2:30 AM and 5:00 AM (I think those are the hours). Where a liquor store cannot sell wine or beer, only liquor. Where a supermarket cannot sell liquor. Where a liquor store can only be open 35 hours per week.
