with jquery, how can select , change css style of text elements inside table cells contain disabled "input" and/or "select" elements? i need iterate on cells in table, see if there disabled "input" and/or "select" elements in there, , if case, text in particular cell should "dimmed" setting css property opacity=0.5. the solution must work in reasonably modern browsers. use jquery :has() , :disabled pseudo-selectors on td elements: $('td:has(:disabled)').css('opacity', .5); if need more specific disabled elements (probably not needed), use :input ( :input covers both select , input): $('td:has(:input:disabled)').css('opacity', .5);

i'd take user input (like ip address) , split parts separate variables for example 255.255.255.0 now, split string decimal points , save each part own variable. 255 variable1, 2nd 255 variable2, 3rd 255 variable3 , 0 variable 4 integers. how can this? you do: a, b, c, d = input().split(".") the split() method, default, splits string @ each space list. but, if add optional argument, split string character/string. can read more @ official documentation you can check make sure input in proper ipv4 format. if re.match("\d+[.]\d+[.]\d+[.]\d+", input()): print("ipv4 format")

i have relation r{id, building, floor, sequence, capacity} where: (building,floor,sequence) -> id id -> (building,floor,sequence) (building,floor,sequence) -> capacity id -> capacity it seems doesn't violate normal form. however, ok id depend on (building,floor,sequence) , vice versa though id primary key? if no, can done? in relation multiple candidate keys, there'll inevitably cyclic dependencies between them - since candidate key can uniquely identify each tuple , each tuple has value each candidate key. the fact 1 key selected being "more equal" others , named primary key irrelevant. (when we're talking abstractly, here. database products may have features indeed make primary key "more equal" alternate keys)

the following code works has problem: #include <atomic> #include "windows.h" std::atomic<int> foo; dword winapi baz(void *) { sleep(10000); foo.store(1); return 0;} int main() { foo.store(0); handle h = createthread(null, 0, baz, null, 0, null); while ( !foo.load() ) { sleep(0); } waitforsingleobject(h, infinite); closehandle(h); return 0; } the program uses maximum cpu while waiting. if change sleep(0); sleep(1); uses 0% cpu, worried couple of things: this introduces unnecessary delay program: waste microseconds if flag set in between polls this might still consuming more system resource necessary, in order wake , call load() every millisecond. is there better way? background: have code working using win32 events wake thread , using waitformultipleobjects , i'm wondering if can use std::atomic flags instead, aim of perhaps making code simpler, faster, and/or more portable. idk how os impleme...
