in 10 common misconceptions couchdb , joan touzet asked (30:16) if couchdb have way secure/validate reads on specific documents and/or specific fields of document. joan says if has access database, he/she can access documents in database. so says there few ways accomplish that: (30:55) cloudant working on field level security access. have implemented yet? open-sourced? (32:10) should create separate document in separate database. (32:20) filtered replications. mentions slows 'things' down. means filter slows replication, correct? also, according rcouch wiki ( https://github.com/rcouch/rcouch/wiki/validate-documents-on-read ), implements validate_doc_read function (i haven't tested it, though). couchdb has it? as far can see, best approach model database according problem (one database this, that, 1 person, person) , filtered replications when necessary. suggestions?

in application of elements inside iframe . so pom (page object model) methods start switching frame , code performing actions..am able perform action switching frame. below example of code: public void method 1() { driver.switchto().frame(0); // code perform actions.... method 2(); driver.switchto().defaultcontent(); } public void method 2() { driver.switchto().frame(0); // code perform actions.... } as per above example, 2nd method called 1st method the driver frame method 1, when method 2 called again tried switch frame 0, hardcoded frame index, thought work fine (i.e driver on same frame), giving error "no such frame exception." is possible know current frame ? if know frame can add condition , decide switch or not switch, please guide. you achieve creating global variable current switched frame below approach :- string currentframe = null; //make currentframe global variable public void switchtoframe(string frame) { ...

when open developer menu (either cmd+d or cdm+ctr+z) none of buttons work. can't close developer menu. seem close after minute or so, don't think it's freezing or crashing, in app frozen out minute , have reset few times. i tried downgrading react , react-native 15.1 , 0.28 15.0.2 , 0.26, respectively. xcode date. i think had same problem few weeks ago. menus slow , and facebook login/logout took forever making me thing froze. turns out had accidentally turned on "slow animations" (cmd + t). check if it's not same problem. slow animations

i'm trying implement standard quicksort in cython using memoryviews. here code: def quicksort_cython(double[:] l): _quicksort(l, 0, len(l) - 1) cdef void _quicksort(double[:] l, double start, double stop): cdef double pivot, left, right, tmp if stop - start > 0: pivot = l[start] left = start right = stop while left <= right: while l[left] < pivot: left += 1 while l[right] > pivot: right -= 1 if left <= right: tmp = l[left] l[left] = l[right] l[right] = tmp left += 1 right -= 1 _quicksort(l, start, right) _quicksort(l, left, stop) however, during compilation standard setup.py file , python setup.py build_ext --inplace command multiple errors regarding memoryview access: error compiling cython file: ----------------------------------------------------...

we collect statistics using atomiclongs. users seeing contention on these , have suggested using longadder instead. see no way calculate maximum value doing atomic: atomiclong _current, _total, _max; ... void add(long delta) { long current = _current.addandget(delta); if (delta>0) { _total.addandget(delta); long max = _max.get(); while (current > max) { if (_max.compareandset(max, current)) break; max = _max.get(); } } so think can replace _total enough longadder , because _current.addandget(delta) not work longadder , nor can cas operation `_max' value. are there algorithms collecting such statistics based on longadder or similar scalable lock free constructs? actually, whiles i'm asking, our stats typically update 6 10 atomiclongs. if seeing contention anyway, possibly better grab lock , update 6 10 normal longs? you don't want longadder , longaccumulator here: want new longaccumulator(...

i've dev first application , make simple map activity, latitude , longitude 0. (when start activity cursor should set in device location). set permission in manifest , google-services.json file, still have error: e/gmpm: googleservice failed initialize, status: 10, missing expected resource: 'r.string.google_app_id' initializing google services. possible causes missing google-services.json or com.google.gms.google-services gradle plugin. i think why cant correct longitude , latitude. activity code: public class ********activity extends fragmentactivity implements onmapreadycallback,googleapiclient.connectioncallbacks, googleapiclient.onconnectionfailedlistener { private googlemap mmap; double latitude, longitude; googleapiclient mgoogleapiclient; location mlastlocation; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_locate_match); buildgoogleapiclient(); ...
