I don't believe it's interactivity that's the problem. I've found that if I play a lot of guitar before bedtime, maybe with singing, I sleep very well indeed. Better than I would if I didn't do anything that evening. And making music is interactive, I'm not passively sitting there like if I'm watching TV. However, if I work on the computer before bedtime it may be that I won't be able to sleep for a while, that typically happens when I'm working on an interesting programming issue and my brain keeps popping up new ideas when I'm actually trying to sleep.

The reason ISPs block TCP/25 is _not_ part of their 'no email service of your own' policy. Blocking of TCP/25 stems from the early days of spamming, when spammers would first relay through, and later hijack consumer PCs for spamming. This was often combined with relaying through a company's mail server, but even when companies got wise to this and changed their setup to not relay, the home PCs could still continue sending spam. Blocking outgoing port 25 put a stop to this (and many companies also block their outgoing port 25, except for their mail server, simply because if an internal computer got infected they don't want to get a spew of spam coming from their network. Just like how the ISPs are thinking). Port 587 requires authentication and in practice only allows you to connect to mail servers you're known to, and there's no reason to block this so the ISPs don't.
As another poster mentioned below: If you show that you know what you're doing, i.e. that there's little risk your computer will be one of the infected spam-forwarding PCs, you can often get your ISP to remove the TCP/25 block.
Well, if it's supposed to be a General Products hull they could install an automatic stasis unit as well. Wouldn't be so bad: ("Warning: Nearing impact."..discontinuity..)
I fly all the time in my job. Look around in an airplane the next time you fly. Notice what people are doing? They close the window shutters as soon as they're airborne, at least when there are clouds. The reason? You fly above the clouds, and the light from the white clouds gets intense. If the sun is on your side of the aircraft it gets even worse.
A transparent fuselage would be a nightmare, except for night-time flying. But how often do you do fly at night, except for intercontinental flights?
To me the whole sounds like a joke, which it probably is.
>So while turning up the power on the headset will make the noise you can >hear 'go away' the damage is still being done.
As has been said before already: The above statement is simply utter bullshit. Go learn some elementary physics please, particularly about how waves interact.
You are absolutely correct. If you don't hear it, the sound isn't activating your inner ear. End of story.
The original parent simply got the physics wrong. Even the reply that talked about "spikes" still coming through is wrong, if spikes were coming through you would hear them. Simple as that. And, having used noise cancelling headphones for years now, I can tell you that this simply doesn't happen.
When being in noisy environments for a number of hours (say, a 15+ hour flight (well, flights), or in a particularly noisy computer room for a couple of days, I would (in the past) always end up with buzzing ears for days and sometimes a week afterwards (I have a small hearing damage in one of my ears because of an accident when I was young). This problem has gone away after I started using the noise cancelling headphones.
(My set is a Sennheiser set, I would love to test Bose but they're hard to get buy (little or no retail), and expensive - so I don't know how good they are. Probably at least as good as Sennheiser, but the latter is the only type I've tried.)
I use my Sennheiser noise cancelling headphones in computer rooms and other places with the same kind of noise, e.g. heavy airconditioning machinery.
I'll never go anywhere near the noisiest rooms again without my headphones. They reduce the noise maybe 15 dB, it might not sound
much but it's the difference of the world, particulary when staying
in there for a long period.
I bought my headset with airplanes in mind, but they work even better
in computer rooms.
Cooling the planet by shading it (or any other means of reducing the sun input) won't help correcting the imbalance. There are _at least_ two major effects of increased levels of CO2 in the atmosphere: 1) Global warming: The sunshade might help. 2) Acidic oceans, and a chemically imbalanced biosphere: Shading basically doesn't help at all.
Conclusion: Shading the Earth just leaves you with an Earth with less solar energy available for photosynthesis, AND it still leaves you with a seriously acidic ocean, with possibly disastrous effects on the biosphere. We'll go from bad to worse.
>known as "DVD Jon" after he cracked CSS encryption at the age of 15.
This is incorrect. DVD Jon made a GUI, the other two guys in his team (one of them a German AFAIK)did the cracking, but Jon was the one with a publicly known identity and was targeted because of that. He's done a lot of cracking since then, but CSS wasn't done by him.
This is well known, particularly among people who posts on Slashdot. Should have been, at least!

Read parent again, it was explained there: Absortion and re-emitting of photons. (And this principle is taken into the extreme where light is "stopped" or slowed down to walking speed - the photons are moving as fast as always, they are simply absorbed and then emitted after a pause (and in the case of "stopped" light that pause is fairly long.)
Photons have zero resting mass, and such particles can never travel at any other speed than C. That's the only speed they can exist at.

The way I see it is that one of the things that Minority Report did best was to show exactly how bad and annoying this type of advertising is.

I regularly visit a customer which owns a building constructed as a faraday cage. It has large windows (3 meters tall) which looks normal to me, but the whole building seems to be very nearly radio transmission proof. E.g., old 450Hz 15-watt mobile phones didn't work, and new 900MHz or 1800MHz GSM phones don't work either. I haven't tested all kind of equipment (after all, that's not why I visit them!) but it appears to be quite efficient in blocking RF.
I once quite by accident met the guy responsible for the building's design, and he told me the building was indeed planned and constructed as an efficient faraday cage from the beginning. On the outside, and the inside, it looks like a completely normal two-floor building with office space and computer rooms.
From what I've heard about this particular petaflop supercomputer in the past is that it isn't a general purpose computer even in principle. It's built for a special purpose and that single purpose is what it can do at petaflop speeds. Nothing else. BlueGene and those in the same range are a bit more general purpose, if you could call it that.
>Isn't charging individuals for banking transactions illegal, under the >same laws that forbid protection rackets?
That depends on the country, I guess. Certainly the transaction fees are so high in my country that you feel like you're paying the bank in order to get access to your own money,when certainly it should be the other way around.
Well, in addition to the arguments already presented (multiple accounts, moving funds between them etc.) it's the simple fact that in my country paying bills over the actual counter in the bank involves charges so high that it's like robbery. The only practical way is to use online banking.
A very good way to block man-in-the-middle attacks is one that has been described by another poster already, and which is in actual use by some banks: Introduce a second channel to verify the actual transactions. In the case described the bank simply sends a one-time pwd as an SMS to your cellphone, you have to enter the pwd to confirm the transaction. The attack used on Citibank customers (and my bank is using something similar) wouldn't work. With this method you won't need those very tedious systems where you have to enter all the accounts and amounts into your OTP device, which is simply painful.
A slightly different SMS-based system (used by some, but it needs a special SIM card) will have you to reply through SMS as well, with a separate personal phone code.
This is mostly a red herring. As long as a) the users (e.g. I) load the drivers (say, NVIDIA driver) and b) said driver doesn't include any GPL material then it is not in conflict with the GPL. It would be a different matter for drivers distributed with the kernel, but for the scenario above there is no conflict.

You don't get it: There's no incompatibility!
What desktop you use does not matter when it comes to which applications you can run.
I used to run KDE, now I use FVWM and I can (of course!) run any of the KDE applications I used in the past, just as I can use any and whatever GNOME application I want. It does not matter which desktop you use.
The point is that some desktops or window managers will be annoying to some people because of the way they choose to work (e.g. some prefer to have lots of desktops with lots of overlapping windows, next door some guy prefers not having any overlapping windows at all, these people will typically want totally different focus/click/to-front/to-back behaviour) and often this is best achieved by choosing another desktop type. But any application will work fine all the same!
This is one of the greatest strengths of X11. Forcing everyone to use the same desktop is like forcing everybody to use the same length skis: It works somehow, but don't tell me it's good for everyone.
What's special about grasses is that grass grow from the bottom, while most if not all other plants have the grow-point at the tip. This means that grass will survive and trive with gracing. If you grace on any other plant you'll eat off the grow point.
Grasses evolved because of extreme gracing pressure. The first plant that had its growing point at the root instead of at the tip got a tremendous advantage and the new species would spread around like, er, grass.
I've been an enthusiastic programmer since I was 17 (now I'm 45), and I've never understood the attraction of roleplaying or any of the other mumbo-jumbo half-assed gaming stuff some people find interesting. Programming and design is creative, interesting and fun work, roleplaying is something totally different.
In my opinion the real-life correlation is between programming and playing a musical instrument, in particular improvised music where a creative mind is also useful.
