i feel i've run issue before , plan on digging old code, has got solution this? for reason, isn't triggering nsfetchedresultscontroller pointed @ parent context update: [[nsnotificationcenter defaultcenter] addobserverforname:nsmanagedobjectcontextdidsavenotification object:nil queue:nil usingblock:^(nsnotification *note) { if ([[note object] iskindofclass:[nsmanagedobjectcontext class]] && [[note object] parentcontext]) { nsmanagedobjectcontext *parentcontext=[[note object] parentcontext]; [parentcontext performblockandwait:^ { [parentcontext mergechangesfromcontextdidsavenotification:note]; } ]; } } ]; basically, if make bunch of changes child nsmanagedobjectcontext , save context, triggers this. however, data shown nsfetchedresultscontroller prior context merge. if quit app , restart it, shows correct data. kind of annoying, missing , can't remember what. i tried this: https://github.com/f

i'm using parse.com features in app, works great on debugging mode. generate signed apk in release mode, have killing wait 10 seconds @ beginning of opening app. it's because of parse.com trying initialize , contact servers, apparently not successful. and also, parse.com stops working know so, since no data uploaded account. there should problem proguard of course since difference between debug , release mode, enabling proguard, in case. i have triend keep com.parse following code in proguard rules: #keep parse classes -keepattributes annotation,sourcefile,linenumbertable -dontwarn com.parse.** -keep class com.parse.* { *; } -keep class com.parse.** { *; } any appreciated! edit: i found out huge memory leak happening @ parse.initialize() after proguard ... still have no idea why though! of course memory leak not present while proguard off try following if have apache http-core , http-mime along parse library: -keep class org.apache.** { *; } -k

i writing program reads gps coordinates. gps coordinates in string format so: 42,9659 15,3167 i want convert these strings decimals. on development pc works fine, put software on pc doesn't convert decimal. outputs value without comma, so: 429659 153167 heres code: gpslatdecimalstring = gpsdata(2).substring(2, gpsdata(2).length - 2).replace(".", ",") gpslongdecimalstring = gpsdata(4).substring(3, gpsdata(4).length - 3).replace(".", ",") 'lat: 25.69953 'long: 28.23881 gpslatdecimal = system.convert.todecimal(gpslatdecimalstring) gpslongdecimal = system.convert.todecimal(gpslongdecimalstring) it seems coordinates in form xxxxx(point)yyyyy , problem in pc os configured different cultures. do not try replace point comma, use instead appropriate iformatprovider in call convert.todecimal gpslatdecimalstring = gpsdata(2).substring(2, gpsdata(2).length - 2) gpslongdecimalstring = gpsdata(4).substring(3, gpsdata

i thought apply ng-disabled <a> element. it's looking can't. works on <button> element. know elements can apply ng-disabled to? you not disable anchor tag. ng-disabled or disabled attribute work on button/input s element, if want disable anchor tag should have call ng-click function on & on basis of either redirect or don't anything. markup <a href="" ng-click="redirect(isvalid, url)"> anchor button </a> code $scope.redirect = function(isvalid, url){ if(isvalid) $window.open(url, "_blank") }

i using datafu's hyperloglog udf estimate count of unique ids in dataset. in case have 320 million unique ids may appear multiple times in dataset. dataset : country, id. here code : register datafu-1.2.0.jar; define hyperloglogplusplus datafu.pig.stats.hyperloglogplusplus(); -- id uuid, example : de305d54-75b4-431b-adb2-eb6b9e546014 all_ids = load '$data' using pigstorage(';') (country:chararray, id:chararray); estimate_unique_ids = foreach (group all_ids country) generate 'total ids' label, hyperloglogplusplus(all_ids) reach; store estimate_unique_ids '$output' using pigstorage(); using 120 reducers noticed majority of them completed within minutes. handful of reducers overloaded data , ran forever. killed them after 24 hours. i thought hyperloglog more efficient counting real. going wrong here? in datafu 1.3.0, algebraic implementation of hyperloglog added. allows udf use combiner , improve performance in skew

we using jquery validate plugin simple field validation. works expected when using default, client-side validation. however, of these fields require server-side validation. problem occurs when manually creating error labels on server in html. when doing so, error label displays expected, behavior wrong. essentially, once error label displayed, won't removed on keyup event of field. removed when press submit button, , first press of submit button hides error label , sets input field valid. have press submit button second time have form submit. appears jquery validate knows error label , it's connected input field, else wouldn't hidden when pressing submit button. things i've tried: setting generated="true" on error label (no change) removing server-side label generation , returning error code creates label on client side validator object, yet behavior same (have press submit button first remove label , second time submit form): var validator

i should complicated tables reorder. ****the main table looks like:**** id - data 1 - ... 2 - ... 3 - ... 6 - ... 9 - ... 12 - ... as can see, there "empty" ids (no 4, 5 between 3 , 6 etc). ****table should like**** id - data 1 - ... 2 - ... 3 - ... 4 - ... 5 - ... 6 - ... 7 - ... etc (without empty ids) why want make it: server database, includes millions ids. server crashes when maintaining such big numbers. if reorder ids , there won't empty ones, max id in table lower , prevent server crashing. the complicated thing - table has foreign key references (only id column references atleast) in 4-5 different tables. my thought is - reorder main table ids without empty ones , create new temp table (oldid, newid) structure , replace oldid's newid's in other related tables. any ideas how query like? take half hour execute query it's least problem.

i have 23 bits represented string, , need write string binary file 4 bytes. last byte 0. following code works (python 3.3), doesn't feel elegant (i'm rather new python , programming). have tips of making better? seems for-loop might useful, how do slicing within loop without getting indexerror? note that when extract bits byte, reverse bit-order. from array import array bin_array = array("b") bits = "10111111111111111011110" #example string. it's 23 bits byte1 = bits[:8][::-1] byte2 = bits[8:16][::-1] byte3 = bits[16:][::-1] bin_array.append(int(byte1, 2)) bin_array.append(int(byte2, 2)) bin_array.append(int(byte3, 2)) bin_array.append(0) open("test.bnr", "wb") f: f.write(bytes(bin_array)) # writes [253, 255, 61, 0] file you can treat int, create 4 bytes follows: >>> bits = "10111111111111111011110" >>> int(bits[::-1], 2).to_bytes(4, 'little') b'\xfd\xff=\x00'

i have project contains bunch of small programs tied using bash scripts, per unix philosophy. exchange format looked this: meta1a:meta1b:meta1c ast1 meta2a:meta2b:meta2c ast2 where : -separated fields metadata , ast s s-expressions scripts pass along as-is. worked fine, use cut -d ' ' split metadata asts, , cut -d ':' dig metadata. however, needed add metadata field containing spaces, breaks format. since no field uses tabs, switched following: meta1a:meta1b:meta1c:meta 1 d\tast1 meta2a:meta2b:meta2c:meta 2 d\tast2 since envision more metadata fields being added in future, think it's time switch more structured format rather playing game of "guess punctuation". instead of delimiters , cut use json , jq , or use xml , xsltproc , since i'm using s-expressions asts, i'm wondering if there's nice way use them here instead? for example, looks this: (echo '(("foo1" "bar1" "baz1" "quux 1"
