i wonder under situation eventfd_read() block? i read manpage doesn't mention anything. i created file descriptor through eventfd(0,0) . thanks in advance. from eventfd(2) man page read() call: if eventfd counter 0 @ time of call read(2), call either blocks until counter becomes nonzero (at time, read(2) proceeds described above) or fails error eagain if file descriptor has been made nonblocking. and eventfd_read() , eventfd_write() functions: the functions perform read , write operations on eventfd file descriptor, returning 0 if correct number of bytes transferred, or -1 otherwise. so eventfd_read() wrapper read() , blocks when read() blocks, i.e. when eventfd counter 0 , o_nonblock not set descriptor (using fcntl(2) or efd_nonblock ). you can verify in glibc sources : int eventfd_read (int fd, eventfd_t *value) { return __read (fd, va...

i'm having trouble php file. i've done connection database can check it. i've got if-else statement in case return of database wanted. thing everytime reload url, echo in else statement, instead of nothing. dont want if-else execute until submit html form i've got. here simple example: if($somethingtocheck){ echo 'hey!'; }else{ echo 'bad!'; } the var $somethingtocheck declared , know right. so explained, if reload url, string bad! in screen, if have not submited form. there's way not execute if-else statement until submit html form? edit: more details problem. you should enclose in block runned when answering post: if ($_server['request_method'] === 'post') { if($somethingtocheck){ echo 'hey!'; }else{ echo 'bad!'; } }

the following: catch :something print true end will print true console. thought point of catch was called corresponding throw . less importantly, there 1 liner syntax? surprised catch :something { print true } raises syntaxerror . why catch block called if there no throw ? perhaps there throw before, , programmer forgot delete catch when throw deleted, or doesn't know how use catch . but more in case failed ask "why catch block executed if there no throw ?" answer question catch block executed point throw raised. if throw not raised, catch block executed. is there 1 liner syntax? yes. don't omit parentheses. catch(:something){print true}

i trying make schedule in google spreadsheets. 1 of features want here have current activity highlighted based on time of day. in formula below, understand a column contains times (first column on picture), , b column contains activities. =and(b$1=upper(text(today(), "dddd")), (today()+$a2)<now(), (today()+$a2+(0.5/24))>now()) b$1=upper(text(today(), "dddd")) checks day indicated @ top of column today (today()+$a2)<now() checks time more what's in a column on same line (today()+$a2+(0.5/24))>now() checks time isn't more half hour past what's in a column on same line using conditional formatting formula, obtain decent result (see picture), when reaches merged cell, it'll work first half hour (in picture, lunch highlighted 12:00pm 12:29pm). to correct that, idea multiply 0.5/24 in last part of formula height (as in number of cells in height) of merged cell is there way in google spreadsheets?
