Programming: Contemporary concepts

*ahem* 3 years limit? well, i didn't graduate this year :|by

fallout 3 is what i'm most looking forward to playing, besides the obvious gta 4 and diablo 3. gonna upgrade my computer next month too so all should be sweet for gaming, just need to decide between 2x 24" or selling the 24" and buying a 30" hmm i should keep quiet while goose is talking about his hit listby

most people are working their current job to get them further along their path in life, not as a final destination; in other words, we are all just saving up money. any job serving this purpose without being too troublesome is greatby

pretty much aced all the linear alebra courses, and did well in the numerical methods ones (closely aligned to my personal and work interests). as for the others, well... i tend to "forget" courses, like mat307 which i am NOT going to write on oct 30thby

yes, they partake of the exotic ritualism too, don't be misled but do what you must to get those marks :| for shame, let there be constants const double d2r = 0.0174532925199432957692369076849; const double r2d = 57.295779513082320876798154814105; ps. http://www.youtube.com/watch?v=TQdIiEUFtqkby

hmmk i see now that the matrix you wrote was indeed a rotation around the z-axis, and that your "two matrix" product was the matrix-vector product (which i suppose is technically true, but i was thrown because it should be a single rotation matrix). anyway, about the angle of rotation (which is clockwise and which is ccw) i'd agree that the right hand rule applies since it wouldby

... and conception should only happen after sex on 3 consecutive days @ god/nature: three strikes please!by

yeah but then you have to do 3 seperate tests (for 3 points), and the matrix rank method does exactly the same test really, just in a much less roundabout way (i.e. more time to do questions which require actual thinking and less number crunching).by

i'm writing 113-q and haven't started looking at any materialby

a digression about homogeneous co-ordinates, aka "those funny extra 0s and 1s you see at the end of some co-ordinates". these have to do with projection, and you can think of them as dividing the xyz components; so position vectors with w=1 leave the point sitting there in space, whereas direction vectors with w=0 seem get shot out to infinity along their given direcion, in other wordsby

maybe they are finally getting around to returning some of my assignments and sent it to you by mistake?by

btw, they should say "co-planar", which means what you expected.by

more generally, if the matrix loses rank then at least 2 of the points are collinear. if the matrix has rank 1 then all 3 points are in a line.by

this one is straightforward linear algebra. the determinant of the matrix whose rows are the U and V vectors is nonzero, and therefore it isn't singular, and therefore the lines are not parallel, and therefore the matrix has an inverse, which you can use to get the point of intersection.by

interpolation is a process by which we "fill in" or approximate unknown data between (cf. outside of, which is known as extrapolation) known data points. as examples, linear approximation fits lines between the known data points, cubic interpolation fits a cubic curve between 4 data points, and the simplest form of interpolation simply picks the nearest neighbouring data point. heby

nope, to rotate around the z-axis you need a single rotation matrix, which will be given in the textbook i'm sure. back when i would give it on the spot it's some transposition of: cos sin sin -cos with 0's and 1's in the right places. it'll be in the book, just look for rotation matrix around z axisby

make a plane with three of them (say p0, p1, p2): e0 = p1 - p0 e1 = p2 - p0 n = e0 x e1 (cross product) d = n * p0 (dot product) then n * p = d for all points p on the plane defined by those 3 points. substitute the remaining 4th point p3 and see if the result is d, if it is then the 4 points are coplanar otherwise they are not.by

in germany, where men are still men, the average family sedan's speed on the motorway is best described as a multiple of c.by

in any case, asm skills are super niche these days, the hot thing now is parallel programming.by

i haven't even started studying, or looked at any of this year's material :|by

so um, no aliens huh?by

mensa is the mcdonalds of high iq societiesby

been working 75+% of the last 3 weeks, per hour :| someday i'll post a link to the result managers don't know what crazy work it is for techies, they're not in the trenches.by
