since few days, when try use tokens publish in wall of user application have error : the access token not decrypted this first time got error , don't understand why. the tokens generated in march still working (i use long lived access , publish_actions). sure, create news tokens (from same application) now, , post fine on wall. (maybe error soon? don't know moment) so why have error tokens generate month (april), except tokens generate (for test)? maybe facebook has changed month in code post? i had similar issue , discovered reason our database stored limited access tokens 200 characters or less our access tokens getting truncated. widened database field 512 characters , things working again me. seems access tokens 219 characters long.

i need function takes list , return unique element if exists or [] if doesn't. if many unique elements exists should return first 1 (without wasting time find others). additionally know elements in list come (small , known) set a. example function job ints: unique :: ord => [a] -> [a] unique li = first $ filter ((==1).length) ((group.sort) li) first [] = [] first (x:xs) = x ghci> unique [3,5,6,8,3,9,3,5,6,9,3,5,6,9,1,5,6,8,9,5,6,8,9] ghci> [1] this not enough because involves sorting (n log n) while done in linear time (because small). additionally requires type of list elements ord while should needed eq. nice if amount of comparisons small possible (ie if traverse list , encounter element el twice don't test subsequent elements equality el) this why example this: counting unique elements in list doesn't solve problem - answers involve either sorting or traversing whole list find count of elements. the question is: how correctly , e...

i thinking way around whole bad habit using infinite loop read in objects. algorithm involves iteratively checking if (fileinputstream("myfile.ser").available() != 0) , deserialize next object. otherwise, close file. i want know if correct way go this. i have read question's answers: may fileinputstream.available foolish me? , don't know if, empty, mean read pointer @ end-of-file. in other words, could trust fileinputstream.available() to check how data still available reading file? no, should never use inputstream.available() anything. method loosely defined (and implemented) mean anything. why infinite loop "bad habit"?

i'm trying date modify check file in vbs script. looks comparison operation depend on date format set on machine script runnnig. have diverse machines regioanal & date settings russian, english us, english uk , need run vbs against machines , being able compare date correctly. when i'm trying use if objfile.datelastmodified = cdate("19.10.2012 11:34:06") else else end if it seemingly works , doing correct comparison on machine russian formats setting, fails on machine english uk formats setting following error type mismatch: 'cdate' 800a000d if use following dateserial(2012,10,19) doesn't throw error fail compare dates correctly. what best , easiest way compare file modify date against predifined value vbs irrespectively of machine date format setting? long story short: don't use localized date formats when parsing dates. iso 8601 format works fine: if objfile.datelastmodified = cdate("2012-10-19 11:34:06") ...

i'm looking lightweight solution kill command output redirection if hangs. current solution if [[ -w /tmp/mypipe ]]; timeout --kill-after 10 5 echo "1" > /tmp/mypipe fi works if left part of command not work correctly (e.g. no 1 read pipe). discovered situation, redirection hangs -- @ least issue of not synchronized tasks, can't solve now. there several related questions this , this or that . last 1 covers question, i'm still looking more slim solution. suggests work like ( cmdpid=$bashpid; \ (sleep 5; kill -9 $cmdpid >& /dev/null) & echo "1" > /tmp/mypipe ) but spawns 2 new bash processes. there more lightweight solution problem? keep in mind each spawned bash process share vast majority of memory parent process, it's not tripling memory usage top have believe. if still want try optimize, timeout 5 tee /tmp/mypipe <<< "1" > /dev/null spawn timeout , tee process instead.

when run isql script file: isql.exe -q -e -i %1 -o %~n1.log then in output file see commands, error of commands see on screen when run. the error doesn't isn't written output file. command should use errors written output file? you have use -m(erge) command line switch in order send error messages output file.
