i'm writing sort algorithm can use stacks. increasing amount of stacks, can sort less operations. anyway, have dataset of 10 integers. difference in memory following (with std::stack ): an array of stacks of size 2 (5 integers per stack) an array of size 10 (1 integer per stack) an array of size 20 (1 integer each in 10 stacks, 10 stacks empty) also, how memory empty stack of int take? int pointer? please treat question academic one. know there better ways of solving problem, can use stacks. the obvious answer is: depends. in reality, there things can said. all of containers incur modest amount of overhead, of order of (perhaps) couple of pointers , couple of integers, @ most. can find out how if want know, constant , quite small, depending on implementation. where c++ standard helps places requirements on storage part of container. because iterators (more or less) equivalent pointers, stack elements placed @ consecutive memory locations same alignment

i making web interface manage hue lamps, struggling when comes color handling.. the api of lamps provides me x , y coordinates http://en.wikipedia.org/wiki/cie_1931_color_space but not z value. i think must calculate z brightness value or saturation value (0 255). but terrible @ colors, , math :p. i tried use thoses functions https://github.com/eikeon/hue-color-converter/blob/master/colorconverter.ts but saw in comments, thoses functions not provide correct values... could me here please ? ☺ ps : need javascript function. okay manage make working of : how convert rgb value xy value phillips hue bulb function xybritorgb(x, y, bri){ z = 1.0 - x - y; y = bri / 255.0; // brightness of lamp x = (y / y) * x; z = (y / y) * z; r = x * 1.612 - y * 0.203 - z * 0.302; g = -x * 0.509 + y * 1.412 + z * 0.066; b = x * 0.026 - y * 0.072 + z * 0.962; r = r <= 0.0031308 ? 1

i have been trying use computer plot hypotrochoids , i've run issues. unfamiliar, parametric equations of hypotrochoid are: x(theta) = (r - r)cos(theta) + d*cos((r-r)/r*theta) and y(theta) = (r - r)sin(theta) - d*sin((r-r)/r*theta) the definition on wikipedia of hypotrochoid can further explain: a hypotrochoid roulette traced point attached circle of radius r rolling around inside of fixed circle of radius r, point distance d center of interior circle. so hypotrochoid values r = d = 1 , r = 3 , should this: but not ending using computing method. hypotrochoid (with same values) looks this: since x , y values determined function of x , y @ angle theta assumed loop through values of theta 0 2pi , calculate x , y values separately @ intervals, plot coordinate in polar form (where r**2 = x**2 + y**2 ), suppose thought wrong. maybe formulae wrong checked on few guys on @ math stackexchange , couldn't figure out what's wrong. methods should us

i want scramble face image. don't know command in matlab programming make face scramble. please indicate me? and want scramble shuffling pixels. you combine randperm , reshape , this: img = reshape(img(randperm(numel(img))), size(img)); alternative solution: "scramble pixel blocks" you this: img = imread('http://www.ricbit.com/uploaded_images/lena-713374.jpg'); blocksize = 64; nrows = size(img, 1) / blocksize; ncols = size(img, 2) / blocksize; scramble = mat2cell(img, ones(1, nrows) * blocksize, ones(1, ncols) * blocksize, size(img, 3)); scramble = cell2mat(reshape(scramble(randperm(nrows * ncols)), nrows, ncols)); subplot(1,2,1), imshow(img); title('source image'); subplot(1,2,2), imshow(scramble); title('scrambled image'); where blocksize width , height of block, in pixels (ex.: 64 x 64) note: blocksize must common factor of original image width , height values.

i have written query aim 10 results including current one, padding 9 entries on either side alphabetical list can sorted reciever. query using, issue not result, but because neither of queries using index . ( select uid, title books lower(title) < lower('frankenstein') order title desc limit 9 ) union ( select uid, title books lower(title) >= lower('frankenstein') order title limit 10 ) order title; the index trying utilize simple btree, no text_pattern_ops etc below: create index books_title_idx on books using btree (lower(title)); if run explain on first part of unioin, in spite of limit , order, performs full table scan explain analyze select uid, title books lower(title) < lower('frankenstein') order title desc limit 9 limit (cost=69.04..69.06 rows=9 width=152) (actual time=6.276..6.292 rows=9 loops=1) -> sort (cost=69.04..69.67 rows=251 width=152) (actual time=6.273..6.2
