Ok, in that case, why are there still limits on key length? If it was just encryption being easily available they would have removed all restrictions because it would make no difference. The ONLY explanation that makes any sense is that they have the capability to crack the length they've allowed.
The US government recently relaxed export regulation for public key cryptography to make it the same as the domestic restrictions. The reasonable implication that we can take from this is that they have a way to crack that length of key, or they know they can do it, if they really have to.
Either that, or the American government suddenly have benevolent feelings to the rest of mankind and a minority of their software community. Yeah right.
A lot of pages are really popular. In that case, all of the proxy servers will quickly cache those pages.
In those cases it's a big win.
In the cases you mentioned, there's still no loss of bandwidth. If the proxies weren't there then you would have reloaded several times ANYWAY; therefore the bandwidth would have been the same.
Of course the latency is pushed up by the cache, but that doesn't cost the ISP anything, and its not as bad as you would suppose, as the proxy server has more bandwidth than the users, so the cache fills quickly.
Rocket engines need high thermal conductivity, to lower the inner temperature of the rocket engine, and light weight. If this material is as good as they say then provided they can sort out any potential mechanical issues this could well be an excellent material to use- graphite works very well anyway, and this sounds like it might work better.
Yes, I had the same problem. There are two ways around this that I can think of:
a) take multiple biopsies of animals and grow from that, as the animals are still alive and healthy, most of the ethical issues go away.
b) find a cancerous growth and grow from that- cancers are immortal
I have a feeling that b) is pretty safe; but I have a stronger feeling that nobody would allow you to feed fish cancers to humans, even though humans immune system would deal with it with ease.
> Also, where the hell do you live that bandwidth is coming down in price?
Actually the cost, rather than the price of bandwidth is coming down all the time. The price of bandwidth is rebounding up now because the dot com craze pushed it down artificially.
Ironically, I live in the UK, and I get my bandwidth from a monopoly, BT; and my price per bit is going down 25% this month, because BT are trying to drum up demand for ADSL. (Seems to be working too.)
The last mile issue is probably going to more or less solve itself, and there is a business opportunity right now to provide wireless connectivity to the offices from bandwidth consumers.
The last mile problem is being quickly solved by a combination of adsl, wireless, satellite.
My favourite is wireless. There's a lot of people think that this is going to be an 'evil steal bandwidth vampire' deal. But I think this is just how the last mile is going to be solved. There's still the problem of how to get packets from town to the rest of the world; you need the ISP/backbone for that; and there will be firewalls you have to log on through which have 'traffic shaping' to stop any one user taking more than they should by loaning it to their friends.
Still, everyone is bleating about the lack of investment, but organic growth on an 80% annual demand curve could be awesome!
Yeah, agreed. We've overshot the real growth in the market and crashed back out, but the real growth (80% growth of bandwidth per year, and the fact that consumers/businesses actually have a thirst for bandwidth that they are prepared to spend money on) is still there.
I expect there may be another overshoot in about 2-3 years time; the cost of bandwidth may go up or stop coming down so fast for a while; and the telecos will start making some money.
Provided the 'edge' of the network, e.g. your ISP checks that you don't have too many high priority packets (i.e. traffic shapes your prioritised packets), then I believe that this is probably fairly workable in fact.
There are some issues if the ISP is crooked of course, but hopefully the ISPs around them would notice that, and take steps to limit the damage. Still, as a rule ISPs are a bit better behaved than users I suspect, because if they lose their reputation then they can lose everything.
Hey, I can beat that. I'll name that language in 1 BIT.;-)
It's in a language I call "WolfWithoutAClausium." In this language, a 1 is interpreted as a universal machine. A 0 is a rabid flying monkey. OK, here's my code:
Any of the P2P mechanisms probably have it already. Have you looked? Nice thing about P2P is that it doesn't matter if it isn't used by the masses, as long as atleast one person with the file is.
Yes. Everyone else has been paying their Microsoft Tax on the English language. You mean you haven't? Oh excellent, there's probably a reward for turning in miscreants like you. Oops, long words like that cost extra; I gotta cut down.
Yeah, I've been doing what most people consider a LARGE development for several years. (i.e. more than 500 software engineers working on several million lines of code... multiple continents); we're currently using Clearcase. Compared to any other tool I've used, Clearcase has a few minor issues, but on the whole it's pretty *damn* excellent, for nearly anything you could want from a source control system.
The few problems we've had are its multisite support is a shade awkward, and if you can't fit all the source into one database the 'intervob' stuff is a bit weird, and it doesn't group changes to multiple files very well. Other than that it's really, really, really excellent.
Still, CVS or even RCS is good too in my experience; but not nearly as polished.
It's quite possible they've broken the law here; as unreasonable as it seems. As an example, if somebody gave you their telephone number, that's probably not classified. On the other hand, if someone hands you their telephone book, that's probably classified. So, reverse engineering their telephone book somehow would mean you have classified information; and that may be illegal. IANAL.
Whether their IP address list is classified, I cannot say... probably not, but I wouldn't like to bet.

Whilst nuclear is one option to get us out there, particularly to the furthest planets, I don't agree that this is necessarily the way to go.
Putting the supposed issues of launching nuclear rockets to one side, all of the issues we know of will be solved by using the existing resources of space, rather than trying to launch every little thing from the earth. Right now we are doing the space equivalent of driving from East to West coast America, whilst carrying all our gas with us for the whole trip. Ever heard of gas stations?
NEOs and the moon have plenty of fuel for us to use, and if you refuel in space, the maximum distances we can go are enormous.
The other issues also become non issues. Radiation? A few tonnes of shielding isn't a problem if you have enough fuel. Gravity? Spin your spacecraft on a tether, and simulated gravity is plenty good enough [the only reason that this isn't proposed right now is mass constraints, also they want zero-g in the ISS for example]. Again, use non terrestial sources for materials, and most issues are gone.
Nuclear is an entirely safe and reasonable approach. But it's not a necessary one. And politically there are huge issues; for what are mostly dumb reasons. But we have to deal with dumb reasons, held by misguided people in life.
Yeah, I agree. You'll need to work especially hard when Microsoft has finished buying your government. I mean, you may think that your Microsoft tax is expensive now...
Sounds to me that Dave's equipment may well be working properly, and the other equipment isn't.
I used to sit next to a radio ham; he related how whenever anyone complained he would hand them a complaint form, they would send it off to the regulatory authority and the authority would investigate and they would deal with it- they would stick a non compliance sticker on the complainers equipment! That equipment is not SUPPOSED to be sensitive to Ham frequencies; it's a defect!
He also related how he was able to reboot somebodies computer remotely(!); and how their computer was radiating like a mad/bad thing all across the Ham bands. In the end he voluntarily shielded their computer and everyone was happier.
Sure, I've got an ADSL line and I often see 50 ms or so. But I sometimes think the game may be a bit more interesting if the minimum lag was bought up to 150ms in a lot of cases. And its not like I suck at low ping- I'm in the top 25 percentile last time I checked (alright that was a bit flukey). I've been known to play on servers in Australia from the UK occasionally. [ Lag of 700ms or so IRC;-) ] No way I would win but my frag/death ratio was about equal. You learn to think ahead. Splash damage is your friend. As you say, interesting mod.
