i have query using pymongo outputting values based on following: cursor = db.collect.find({"index_field":{"$regex":'\s'}} document in cursor: print document["_id"] now query has been running long time (over 500 million documents) expected. wondering though if there way check query in execution perhaps finding out last printed "_id" in indexed field. last printed _id halfway through btree index? near end? i want know see if should cancel query , reoptimize and/or let finish, have no way of knowing _id exists in query. also, if has way optimize whitespace query, helpful to. based on doc, seems if of used ignorecase of been faster, although doesn't make sense whitespace checking. thanks much, j query optimization your query cannot optimized, because it's inefficient $regex search that's looking space \s in the document. can do, search $regex prefix of \s , e.g. db.collect.find({"index_field&q

i have 2 awk scripts run in linux. output of each 1 in 1 line. how can separate 2 output 2 lines? for example: awk '{printf $1}' f.txt >> a.txt awk '{printf $3}' f.txt >> a.txt the output of first script is: 35 56 40 28 57 and second output is: 29 48 73 26 if run them 1 after another, output become: 35 56 40 28 57 29 48 73 26 is there way result to: 35 56 40 28 57 29 48 73 26 thank you!~ although don't understand how manage spaces between fields way it, can add end statement first script: awk '{printf $1} end{print "\n"}' you can single awk command: awk -v ors=" " 'begin{argv[argc++] = argv[1]; = 1 } nr!=fnr && fnr==1 { printf "\n"; i=3 } { print $i } end { printf "\n" }' f.txt

i need regex or php preg_match function should extract youtube/vimeo url , video provider/domain name (vimeo/youtube) string containing video url. and extracted video url of string, need find exact video id. the regex should graph video id below url also, youtube https://youtube.googleapis.com/v/jgyzdgpv_hk vimeo https://vimeo.com/channels/staffpicks/167414855 thanks, working on solution. post answer if find it. $sample_text = "cieker largest talentize social , professional networking website, can view on https://www.cieker.com , video on https://www.youtube.com/watch?v=jgyzdgpv_hk"; // function return video url string function extract($html) { $regex = '/(http:|https:|)\/\/(player.|www.)?(vimeo\.com|youtu(be\.com|\.be|be\.googleapis\.com))\/(video\/|embed\/|channels\/(?:\w+\/)|watch\?v=|v\/)?([a-za-z0-9._%-]*)(\&\s+)?/'; preg_match_all($regex, $html, $match); $matched = array_unique($match[0]); usort($matched, function

i'm having trouble trying fill static map values arguments of enum. example of i'm trying here: public enum lettersandnumbers { a(1, 2), b(2, 3); private static hashmap<integer, integer> numbers = new hashmap<integer, integer(); private lettersandnumbers(int numberone, int numbertwo) {} // somehow put arguments "numberone" , "numbertwo" map public static integer getnumbertwo(int numberone) { return numbers.get(numberone); } } is there way access these variables in static block, or elsewhere outside of constructor? have been looking around while now, find nothing on it. thanks in advance. you need store numberone , numbertwo in enum fields . can use static initialization block iterate values() , store them in map . like, public enum lettersandnumbers { a(1, 2), b(2, 3); private int numberone; private int numbertwo; private static map<integer, integer> n

i'm using immutable.js typescript build redux app. essentially, state looks like const defaultstate = { booleanvalue: true, numbervalue: 0, } const staterecord = immutable.record(defaultstate) class stateclass extends staterecord { booleanvalue: boolean numbervalue: number } const state = new stateclass() (this setup enables compile-time type checking expressions state.booleanvalue === 'hi' ) is there way enable compile-time type checking set , such state.set('booleanvalue', 'hi') ? (i want warning compiler saying 'booleanvalue' cannot set 'hi' .) or, there alternative setup make immutable.js , typescript work both when getting , setting? is there alternative setup make immutable.js , typescript work both when getting , setting not without wrapping staterecord in helper functions (basically throwing more code @ needs duplicated , kept in sync). in short nope.

so right have list of directories wanted through regex pattern , linq filtering. need way folders contain number of directories , skip ones without 1 , how check if directory info empty or not . suggestions ? have far directoryinfo root = new directoryinfo(@"c:\users\jphillips\desktop\test"); var dirs = new list(); dirs = root.getdirectories("*", searchoption.alldirectories).where(d => reg.ismatch(d.name)).where((d => !d.fullname.endswith("tests"))).where(d => d.getfiles().length > 3).tolist(); foreach (directoryinfo dir in dirs) { console.writeline(dir.fullname); } can tell me how filter here, , * mean in directories function heres starting point suppose: var diprojects = new directoryinfo(@"c:\projects"); var subfolders = diprojects.getdirectories(); (var = 0; < subfolders.length; i++) { console.writeline(string.format("[{0}] {1}, directories = {2}, files = {3}" ,
