Dimensions can't be negative[...]

... why not?

[Max White]

Because it is 11:30 at night and if it isn't euclidean, I don't want to fuck with it.
And you know what else? Pi is exactly 3.14! Anything else is a mistake. It might be irrational tomorrow after a cup of tea, we shall see.

Except it need not be a positive integer. Well at least taking some definitions of the word. Video games are a great example, because they are some what self contained universes with two or three dimensions that use nice, simple euclidean, Newtonian physics. Anyway it is very easy to be at a negative or a decimal, and these still count as dimensional places.

Although this isn't always true. In software arrays you are limited to positive integers, but that doesn't make it the rule for all things thought of as a dimension.

Wait, what? How can you have negative number of coordinates? That doesn't make any sense. You can have 0, 1, 2, 3,..., n coordinates, but -1, -2, -3,..., -m coordinates? Or even noninteger number of coordinates. That's like saying you have one and a half man (not including Tyrion). I think you're confusing number of coordinates with the value of a coordinate.

Like in 3-dimensional space, you need 3 coordinates to represent a point in that space. The space has a dimension of 3. But let's say that dimensional is R³, then a coordinate can take any number k in R as its value.

Actually, you can have non-integer dimensions with an extended definition of dimension, namely the Hausdorff dimension definition, which is defined for every metric space. For example, the dimension of the Koch snowflake is log(4)/log(3).

Then clearly I'm using a different definition of dimension.

Vector spaces rule and I'm sure Vector would approve.

The above conversation is better suited to the programming/math threads.

[scriver]

No, I'm fairly certain everything math also fits the rage thread

... You guys keep remindin me why I'm goin into squishy-sciences rather than theoretical mathematics.

Dear reasonably tech-saavy customer:

Please stop shouting your tech rants in my ear. Seriously. You talk about how the other people you deal with in tech treat you poorly or ask you questions like "Why are you so hateful?" "Why are you so angry?" Answer? It's because you're incapable of expressing your opinion without your voice going up several decibels in volume. Yes, yes, I get it, Microsoft sucks, Yahoo sucks, free programs suck, people that don't know tech suck...But I'm not your therapist. I'm YOUR tech support. Treat me as you'd like to be treated yourself. I'm polite, accommodating and I don't yell. Pretty please, with pounds of sugar on top, do me the same fucking courtesy. I get you're thrilled you've finally found someone at this company that doesn't cut you off or refuse to listen to you. I'm glad to fill that role, as the guy who you can talk to. But I require our conversations not to meander into your personal, angry rants that have fuck all to do with the thing you called me about.

Word of the wise: if you are going to buy a weight lifting machine, make absolutely sure that it doesn't use plastic pulleys. Unfortunately, they really like to hide what the things are made of. If it refuses to tell you, don't buy it.

The cables usually dry out really quick, for no good reason.

I was at the library on one of the computers, and left it for about a minute to go look at some books. When I got back someone had taken my flash drive (which I left in the computer, and which had a ton of work on it) and logged off of the compuer. God Fuckin Damn it.
EDIT: ASOFINSDOIHPSAOHDPIASFHU. GODAMNIT.
EDIT2: Wow, I am exceedingly dumb. It turns out that I remembered to put it into my pockets before I left the computer. I did check in my pockets right after I found it missing, but I obviously missed it since I have a fair amount of stuff in py pockets). I was pretty sure that I had left it at the computer, but obviously I didn't.

Someone still logged my out though, which did kill a fair amount of my work.

Ditto~

Appropriate.  I was plugging for La-Mulana.

Eh, I'll just wait for the winter sales.  Ah'm playin' Ass Creed and Buttman at the moment.
