is there way convert undefined, nan, etc. values in javascript object blank string (so it's @ least defined). ex: javascriptobject = defineundefined(javascriptobject) something works that. one idea might check if value nan, , set equal 0 (or value of choosing). if (isnan(x)) x = 0; for more information on isnan, can take here: https://developer.mozilla.org/en-us/docs/web/javascript/reference/global_objects/isnan

i have created custom field ( select box) post type - flavors. custom field type can have flavors vanilla, chocolate etc.. set @ run-time administrators. i have requirement, need list values @ run time has been set custom field type choices. how do this? get_post_meta return value set particular post id. if understand requirement right (and tbh i'm not sure), following code should need. global $wpdb; $flavors=$wpdb->get_col('select `meta_value` `' . $wpdb->prefix . 'postmeta` `meta_key`=\'flavor\' group `meta_value`;'); if (count($flavors) > 0) { foreach ($flavors $flavor) { //do whatever need $flavor (meta_value) } }

i wondering if can enhance search facility in mediawiki, returning suggested result set closest search key instead of return 0 results page. for eg. have created ff: articles, guidelines database management guidelines sql reporting but when try search entering guidelines , instead of showing me or suggesting me close, returns 0 results prompting me if want create it. would little suggestive, can make little suggestive? try installing lucene in place of default mediawiki search engine, merely mysql full-text indexing. lucene not solve above problem, work if you'd mistyped "guidlines" , ask, "did mean 'guidelines'?" http://www.mediawiki.org/wiki/extension:lucene-search http://www.mediawiki.org/wiki/extension:mwsearch lucene nontrivial install, results worth it.

i have vector of widths, ws = c(1,1,2,1,3,1) from vector i'd have vector of form: indexes = c(1,2,3,5,6,7,9,11,12) in order create such vector did following loop in r: ws = c(1,1,2,1,3,1) indexes = rep(0, sum(ws)) counter = 1 counter2 = 1 last = 0 for(i in 1:length(ws)) { if (ws[i] == 1) { indexes[counter] = counter2 counter = counter + 1 } else { for(j in 1:ws[i]) { indexes[counter] = counter2 counter = counter + 1 counter2 = counter2+2 } counter2 = counter2 - 2 } counter2 = counter2+1 } the logic follows, each element in ws specifies respective number of elements in index. example if ws 1, respective number of elements in indexes 1, if ws > 1, let 3, respective number of elements in index 3, , elements skipped 1-by-1, corresponding 3,5,7. however, i'd avoid loops since tend slow in r. have suggestions on how achieve such results vector operations? or more crantastic solution? thanks! here...

i'm working test chunk of code - it's class called mazebuilder. problem of methods protected, can't access them in tests... so thought test should focus on run(), accesses lot of other methods. i'm concerned impossible sort of cohesive testing done operating 1 method. additionally, proper way test 2 constructors ( mazebuilder() , mazebuilder(boolean deterministic) )? stands, i'm testing object formed not null - i.e. they're being built @ all. there more expansive way of testing constructor i'm unaware of? package falstad; public class mazebuilder implements runnable { // given input information: protected int width, height ; // width , height of maze, maze maze; // reference maze constructed, results returned calling maze.newmaze(..) private int rooms; // requested number of rooms in maze, room area no walls larger single cell int expectedpartiters; // user given limit partiters // produced output in...

i have following document: { "_id": objectid("5241f1d79b7e7aed05000000"), "description": { "nl": "hallo", "en": "hello" }, "name": "marc" } now need update update 1 existing field or add new field description. in php use update function mongo , following code: $new_data = array( '$set' => array( "description" => array( "de" => "hallo" ) ) ); what removes other fields , insert "de" field. tried replacing $set $push (which thought made this) no result $setoninsert not anything. how can solve problem can either add new field (if not exist) or update if exist. thanks just make update {$set: {"description.de": "hello"}} i guess in code be: $new_data = array( '$set' => array( "description.de" => "hallo" ) )...

i'm trying retrieve latest set of rows source table containing foreign key, date , other fields present. sample set of data be: create table #tmp (primaryid int, foreignkeyid int, startdate datetime, otherfield varchar(50)) insert #tmp values (1, 1, '1 jan 2010', 'test 1') insert #tmp values (2, 1, '1 jan 2011', 'test 2') insert #tmp values (3, 2, '1 jan 2013', 'test 3') insert #tmp values (4, 2, '1 jan 2012', 'test 4') the form of data i'm hoping retrieve is: foreignkeyid maxstartdate otherfield ------------ ----------------------- ------------------------------------------- 1 2011-01-01 00:00:00.000 test 2 2 2013-01-01 00:00:00.000 test 3 that is, 1 row per foreignkeyid showing latest start date , associated other fields - primaryid irrelevant. i've managed come with: select t.foreignkeyid, t.startdate, t....

i have code in unit test waits until vector sufficiently big: bool waitforoutwardmessages(size_t size, int millis) { std::unique_lock<std::mutex> lock(mutex); return ready.wait_for(lock, std::chrono::milliseconds(millis), [=]{ return this->messages.size() >= size; }); } std::mutex mutex; std::condition_variable ready; easy enough. except when run test, i'm expecting the vector in question should fill on order of milliseconds after make call on other thread. maybe 10ms, maybe 100ms, within 1s. when pass in 5000 millis argument, function always waits 5 seconds. on 1 hand, fine, because don't care how long test takes anyway. on other hand, thought supposed wait duration if condition variable wasn't notified... not always? is there way return earlier? check calling signal or broadcast on ready . there's possible race if you're not careful can signal condition before wait on (which cause wait until timeout).

i have while loop continually processing information on weekend. on monday @ 8:00 process stop. i have running inside while loop: datetime currentdate = datetime.now; if (currentdate .dayofweek == dayofweek.monday) { runloop = false; } this should correctly stop loop turns monday right? how enable continue until 8:00 on monday morning? it sounds me it's simple as: datetime currentdate = datetime.now; if (currentdate.dayofweek == dayofweek.monday && currentdate.hour >= 8) { runloop = false; }

what best way reference user model in django >= 1.5? after reading referencing user model , i've started using (1) while: (1) from django.conf import settings django.db import models class article(models.model): author = models.foreignkey(settings.auth_user_model) but following zen of python, readability counts, why not this: (2) from django.contrib.auth import get_user_model django.db import models user = get_user_model() class article(models.model): author = models.foreignkey(user) update: of django 1.11, get_user_model can called @ import time, in modules define models. that means this: models.foreignkey(get_user_model(), ...) original answer (django <= 1.11) you might experience circular reference issues if use get_user_model @ module level. option importing auth user model is: from django.conf import settings auth_user_model = getattr(settings, 'auth_user_model', 'auth.user') # models class article(model...
