is-there word generalizes notion of pixel , voxel dimension ? similarly, superpixel / supervoxel. referring "superpixel or supervoxel" method can operate on both isn't quite nice. if not tied dimension, , "voxel+time" or "supervoxel+time" etc. commonly accepted term ? look @ etymology: pixel = picture element, voxel = volume element. given picture 2d space , volume 3d space think best term "space element", or "spaxel". made on-the-spot. interestingly, after 5-second google search wiktionary supports definition: http://en.wiktionary.org/wiki/spaxel blend of space , pixel, introduced in 2012 paper spaxels, pixels in space: novel mode of spatial display (horst hörtner, matthew gardiner, roland haring, christopher lindinger, florian berger).

i in process of developing php login system. implement restriction users cannot use password have used (up 5 old passwords). best option storing passwords? came 2 idea's: 1) table: password column: passwordid, userid, password1, password2, password3, password4, password5, lastchanged, currentpassword. each user have own row. fill columns on time , rewrite accordingly. or 2) table: password column: passwordid, userid, password, datechanged. each user have 6 rows. php handle figuring out of current via date. option 2 better of 2 options except don't have worry deleting rows. rdbmss have way of selecting top n records based on something. the major reason option 2 better, if either increase or decrease number of records have queried, can update database record.

i have bit array prime[] of unsigned int . wish implement sieve of eratosthenes using array, having each bit represent number n . is, given n , array element holds bit corresponds n prime[n/32] , specific bit in position n%32 . my testbitis0(int n) function returns 1 when number prime (if bit == 0), otherwise 0: return ( (prime[n/32] & (1 << (n%32) )) != 0); my setbit(int n) function sets bit 1 @ corresponding position: int = n/32; int pos = n%32; unsigned int flag = 1; flag = flag << pos; prime[i] = prime[i] | flag; the issue i'm having when call setbit multiples of prime number, don't think sets bit correctly. when call setbit multiples of prime number (such 4, 6, 8, etc. number 2) next time run line: if(testbitis0(i)) { ... } with i = 4/6/8/etc still return 1 when should return 0. can please check code make sure implementing correctly? thanks. this looks you're after. there's bit array , bit twiddling function...
