Working backwards (starting with your conclusion and trying to simplify it into a known true statement) can be useful as a way of seeing where you're going, but it's not a valid method of proof unless you show that all steps are reversible (proving the converse as well as the theorem, which may not always be possible). Unless you can do it reversibly, you have to rewrite the proof in the forwards direction, and your example of a multiply zero becomes a divide by zero, which indicates an error. Multiplication by zero will never cause an error unless some other mistake is made.
does any detractor need to precisely pinpoint where the error is "on page 13, where they get from equation 63 to 64, they effectively multiply both sides with zero"?
That's not an error. It *does* wipe out your current line of reasoning, but the resulting equation, 0=0, is valid. Dividing by zero, OTOH, is a serious error:
Meh, I like KDE. I don't have anything particularly interesting to say about it, and I'm bored. I saw your post, and thought, "I wonder if he's drunk" for no particular reason, so I asked for no particular reason. That's it.
And dude, the offended bit is my sig. Are you drunk?:P

Duh, the *battery* is 2,200 years old. The article is only 65, and is conclusive proof that there was writing in iraq when the rest of the world was too depressed to even read.
So we either (possibly) lose some priceless artifacts [and some worthless millions of iraqi lives] , or we lose priceless [american] lives when the next [and first, from iraq to US, "]terrorist["] strike comes.
As often, the problem lies in backwards compatibility with windows 9x, which had no multi-user support (profiles don't count) and thus spawned programs which presumed to be able to write wherever they want.
NVidia missed a manufacturing cycle and now it's coming back to haunt them. They really need to drop [the next manufacturing cycle] and concentrate on [another big change].
So performance wise nvidia appear to be relying on developers to optimise their applications specificaly for the geforce fx. And they probably will get it too given their current market share.
But what matters is the FX market share. They've gone for something "revolutionary", rather than the incremental Geforce 1, 2, 3.. n. If it's too late, or overpriced, or badly marketed... we all know what happened to 3dfx.
Don't read the story, don't read the write up, don't even read all the posts, but please read the thread you're replying to, where it is pointed out that this was a bug that can be fixed without impacting performance.
I had mod points and was going to use them in this forum... but I just couldn't resist replying to your post because there just simply isn't any foundation to your claims.
Thanks. He wasn't offtopic, or trolling, or flamebait, or redundant. There is no -1 Wrong moderation, replying is *always* the way to go if you disagree.
As a result we have a dominant OS that's insecure and a secure OS that's mostly unusable by anyone who is not a third generation sysadmin. In all that rush no one had the time to write an OS that's is BOTH secure and user-friendly. Flame away:)
I realise that the sysadmin comment was facetious, but you *did* say flame away;)
Yes, realistically, linux *IS* harder to learn than windows (learn, not neccesarily use). However, if you will settle for *only* using a windows-like interface, mandrake and lycoris are pretty damn accessible. Windows (in the easy-peasy sense of the word) is a *user's* operating system. Sysadmining isn't just point-and-sneeze in windows either.
Xboxes aren't sold in Australia's largest electrical chain stores because M$ won't sell Xboxes to them unless they dropped Playstation and M$ was told to get lost.
Wow. Not wow because they got told to get lost, wow because they had the gall to ask in the first place. If MS is selling these for less than cost, how much can the dealer be making? And add that to the fact that XBoxen aren't selling nearly as many as PS2s. Here in NZ I haven't seen any shops selling XBoxen that don't sell PS2s, so maybe microsoft backed down?
I'm sorry, in looking at the belt to notch it, you read the copyrighted branding information on it, thereby making a copy of it in your brain and circumventing the "too-embarrased-to-look-at-someone's-crotch" copy protection that these belts use. You have the right to remain silent, unless exercising that right would allow you to circumvent the copy protection of the list of rights I am now reading to you by the use of your "ears", a pirate hacker tool.

That's not an error. It *does* wipe out your current line of reasoning, but the resulting equation, 0=0, is valid. Dividing by zero, OTOH, is a serious error:
1 = b
b = b^2
b - b^2 = 0
b(1-b) = 0
b = 0
1 = 0.
These \psi_s (t) vectors are also all at "right-angles" to eachother. So their cross products = 0.
No, their dot products = 0. The cross product of two vectors is a vector perpendicular to each.
Every tradition has to start somewhere, right?
If you're gonna use an obscure acronym three times, write it in full the first time.

Well, obviously, every snowflake is unique!
I'm being curious, if that's okay with you. I'm also being right.
Are you drunk?
Bah, you're both wrong. Stalac"mite" as in "mite not ever need to know the difference, if i'm lucky."

Better double check that, this may be a false alarm, like the "Otensibly" of '98 and the "Ostensibly" of 2001.
