I've got a 3Mbps (same both ways) wireless connection to the Univerity her ein Bergen. We're using Breezecom's SA-10 boxes, which cost about $700 to buy, which suck. But then again 3Mbps and ping times from here to the University-campus of generally around 8-15ms is sweet. Double that ping to reach central servers in Norway.
Methinks ground-based will always have the edge both when it comes to bandwith and to response. REsponse for the obvious reason that sattelite is slow for reasons of ligthspeed which are unlikely to change:) Bandwith because sattelites/are/ farther away, and because they've got a larger footprint on each transponder, so you've got more people to compete with.
Actually, a square wave at Xhz consists of an infinite number of sin
waves One of which has the frequency X, and the others having
frequencies 3X 5X 7X and so on.
If you've got a graphical calculator, or gnuplot, ask it to plot:
With these first 5 you get a pretty good representation of the square
wave, but perfect it can never be, for that you'd need an infinite
number of terms.
Notice however that the 5th part here has the frequenzy 9x, so if you
want your system to be able to represent it, it follows that X must be
smaller than 1/9th of the highest frequency your equipment can handle.
People can hear frequencies up to something in the 20Khz range, that
means they can hear the components of a signal whose frequencies are
lower than that.
So yeas, to represent a square wave at 22Khz fairly well you'd need to
sample at atleast 100Khz, preferably 200Khz. But if the purpose is to
play music for human ears then it simply/does not matter/. Because
the human ear will only hear those components whose frequencies are
less than 20-something Khz.
Most "audiophiles" are idiots. Fed by marketing hype from companies
who're happy to feed idiots expensive equipment that serves no
purpose. For instance most audiophiles do not understand what the term
"digital" means. One of the things it means is that/any/
pickup-mechanism that reads a 1 as a 1 and a 0 as a 0 is equally
good. It's entirely pointless spending money on more expensive and
"better" cables and pickup-assemblies to read and transmit the ones
and zeroes. As long as every 0 stays a zero and every 1 stays a 1, it
makes No difference at all
I salute the efforts of organizations such as Amnesty International, who work for freedom in other nations.
It is somehow annoying to yet again meet Americans who're all convinced of facts such as the above. Amnesty works to end all violations of the human rigths. If you think this is "in other countries" only, I suggest you go visit Amnesty's website and have a look for yourself.
It's true that the US isn't by far the worst country with respect to human rigths, but it's very far from the best too. Which two countries has not ratified the UN convention on childrens rigths ? Answer: Sudan and USA.
In particular the death penalty thing is stupifying to an European. Over there it's even used for getting cheap votes. Had a look at the statistics for number of executed after Bush decided he wanted to be elected ? If not I suggest you go have a look.
Regardless of your opinion on death penalty, I can't imagine you find it okay to execute a lot of people as fast as possible for gaining a few votes...
It is possible to buy perfectly normal computers of the type commonly used to build Beowulf-clusters outside of the USA.
Assuming that say Iraq won't be able to buy a pile of Alphas, or K7's if they so wish is utter bullshit. The US may ofcourse choose not to export such computers to those countries, but what is to stop some person from buying the vary same boxes in some other country and shipping them to Iraq then ?
It's not as if all countries have export-regulations equally silly as the US.
You're rigth, if the OS doesn't know the cleartext-bits, it cannot copy them. However,theres one large problem with this.
Imagine that you instead of mpeg-encoding the movie and putting that on the dvd or wherever, in encrypted form, like with current dvd-movies, you instead put the encrypted bits on the dvd, and have the os merely stream these bits to the display, without ever knowing the cleartext.
What happens is that compression won't work. That is because a prime charateristic of any encryption-method I know of is that the encrypted stream looks completely random, and as such it's not compressible.
Try it yourself: make a text file, then first encrypt it in your encryption-program of choise, and thereafter compress the encrypted file. Doesn't work. On the other hand, first compressing the text-file, and thereafter encrypting it, works fine, and that's how it's currently done dvd-movies.
This is no idle point. Abandoning any and all compression of the video makes the files a lot larger for similar quality.
You migth argue it's public or it's not, however, the GPL makes no mention of "public distribution". It simply talks about distribution.
Now, if putting software on a CD, and mailing it to hundreds or thousands of users who has requested the software isn't distribution, then what is ?.
Also, they must've missed the point. A beta program is to iron out bugs, surely it's much easier for a beta-tester to assist in finding and fixing bug if he's given the sourcecode to the program he's testing ?
What they're doing is stupid. And it's illegal. I find it quite likely that their legal dept. simply did a foul-up and that it'll be fixed quickly, but I still think it's sad that Corel hasn't really understood anything at all.
Sure. On more suerpcomputing site, probably with hardware matching close to 5% of the hardware NSA employs already. I'm sure that'll change the world. Afterall, it's well known that what's really needed to get rid of famine, poverty and homelessness is more number-crunching. Get a grip Katz. These issues are political, and will remain so even if supercomputers _can_ help analysing somre problems better.
You are being real clueless Taco !

Filled mailboxes is only part of the problem of SPAM. It comes down to if it`s acceptable that recipients should pay the larger part of the bill to receive advertizing. My answer is _no_.
I don`t care to receive advertizing at all, and if I do I _certainly_ won`t accept paying for it too.
Why anyone would want Office is beyond me. It's got several of the problems that makes Windows so bad. It's proprietary, including it's dataformats, thus forcing you into an endless upgrade-spiral.
I can't even begin to count those I know that have upgraded to the newest Office, not because they need it for any reason, but because their friends upgraded, and they can't read their documents without upgrading.
Word Perfect, while also proprietary atleast has kept it's data-format unchanged trough it's latest 3 revisions.
It's not quite that simple. Consider how it's possible that more stocks are bougth than are sold.
hint: Unless the company in question issue new stock the number of shares sold will always equal exactly the number bought for the simple reason that every share bougth is sold by someone else
The US aren't alone in having strong crypto. Blowfish, for starters are Swiss as far as I know. (though it's still illegal to export American products using blowfish to switzerland - go figure)
I wouldn't at all be surprised if MS tried a trick like this. We've already seen AstroTurf and the fadese with the faked video in court, this is no different.
They probably wouldn't risk it just now though, the chanse of something like this leaking would be large.
Still, I found it hard to believe they'd actually go fake a video and show it to the courts too... They're silly enough that it _may_ actually be true.
I happen to agree with Katz on this one. But I fail to see why it's of interest to anyone what he think of the matter.
We all know there's good and bad sides to having ACs. I think the good sides outweigh the bad ones.
But that doesn't mean I submit this opinion of mine as a headline. What's interesting about it ? Theres no information whatsoever in your story Katz. All there is is a repeating of one of your favourite themes, the one about how much nicer people are in email than in public forums.
we've heard it before. It wasn't news the first time, and it's not getting fresher.

Sure. But if you simply want to block jpgs, what's wrong with a simple procmail recipe ?
How about "exists for my OS" ? For an actual advantage I mean ?

"As many as 27 million copies may be in use"
:-)
Now, I've seen numbers up to maybe 10-12 million. But 27 ? I don't think so. Not yet

AS stated by the creator - running under a flawed os such as Windows makes PGP vulnerable
Actually being readable by a Word process makes the key vulnerable. Thus PGP should refuse to run if Word is installed on the machine in question
