C++ & Qt: Don't pick a random number for x minutes -

-
let's have 10 numbers 1 10 , rand() picks number 3. number displayed on screen, but won't shown 15 minutes after picked . how can that? i know srand should used better random results, that's not want achieve. want specific number shown once, after not appear until 15 minutes gone. i've read sleep, haven't figured out how works , if fits problem. one straightforward way: keep record of numbers they're picked , time they're picked. so each time want display number: check record , remove entries older 15 minutes. pick number between 1 , 10. check record see if picked number has been used in last fifteen minutes. if go step one. since picked number hasn't been used in last 15 minutes, display number. add new entry record picked number , current time. note obviously, if pick 9 numbers in less 15 minutes, , tenth number picked within 15 minutes, result not random @ all. point being kind of constraint results less random more numbers ...

i'm trying pin down problem grobwidth applied gtable objects (see gtable:::widthdetails.gtable ); issue arises when size specified sum of units ( unit.arithmetic object), library(grid) u = unit(1,"npc") + unit(2,"mm") grid:::absolute.units(u) #error in usemethod("absolute.units") : # no applicable method 'absolute.units' applied object of class #"c('unit.arithmetic', 'unit')" remarkably, absolute.size works, though calls grid:::absolute.units , grid::absolute.size(u) #[1] 1null+2mm how possible? ok, browsing grid source code , found out method is defined, grid:::absolute.units.unit.arithmetic(u) but it's not exported. absolute.size() knows it, because it's in package namespace, calling outside (e.g. gtable) fails.

shell - fgrep or grep -F, which one is better for portable script? -

-
i having controversial commentary on this answer question whether should use fgrep or grep -f switch (i.e grep -f ) portability. points have been came light far are: grep -f : is posix standard. gnu grep has declared fgrep deprecated. fgrep : historically came before grep -f option. even though gnu grep declared fgrep deprecated, seem stick historical use. if consider old (really old) systems, can find of them not having grep -f in them (and think chance of happening rare). need worry very old machines , avoid posix standard that!! if think current situation , include old machines (which supposedly/allegedly don't have grep -f ), there more systems supporting fgrep . on other hand, if future, fgrep going history , grep -f triumph upon posix standard. and isn't accepted practice use posix standard better portability? this question bit opinion based. i'd put 2 cents here :- as mentioned fgrep going history , grep -f posix stan...
