i trying simulate gc in local environment. there way can make jvm hang 5 mins? if on linux system (most other unixes have this), can do pkill -stop java; sleep $(( 5 * 60 )); pkill -cont java to pause java process 5 minutes. pkill -tstp java; sleep $(( 5 * 60 )); pkill -cont java is less agressive. but nowhere garbage collector break .

i have string @str =11,22 in variable. how can insert table like, id num ------------- 1 11 2 22 here's simple way you're looking although dependent on values being split comma , having no spaces (although can use trim if believe happen): declare @str varchar(10) = '11,22,33' declare @foobar table (id int identity (1,1), num int) while (charindex(',', @str) > 0) begin insert @foobar (num) select left(@str, charindex(',', @str) - 1) set @str = (select substring(@str, charindex(',', @str) + 1, len(@str))) end if len(@str) > 0 insert @foobar (num) select @str select * @foobar and here sql fiddle: http://www.sqlfiddle.com/#!6/0e240/2/0

i beginner in matlab. saving file using, eval(['save(''results/loc_', num2str(location) ,''',''values'')']); i have 54 locations. in case save 54 files named loc_1,loc_2...loc_54 in new folder named 'results'. size of each file 15x7. in case number of columns remain same. number of rows change. if take 1 trial,then 'loc_1' give 3x7 values. if take 2 trials, 'loc_1' give 6x7 values , on. in case want take 'trial' variable , value 5. each file named loc_1,loc_2,..,loc_54 give me 15x7 values. now want separate first 5 rows (and 7 columns) loc_1 , need save them in 3 different files , size of each file 5x7. have save loc_numstr(location) files (that total of 54 files) , separate them this. have 3 sets of 54 files of each size 5x7. in case taking 5 trials, separating 5x7 size of each file. 4 trials, need consider 4x7 , on. any kind of appreciated. thanks. i think made bit complicated. can explain m

i learning haskell , curious following: if add element list in haskell, haskell returns (completely?) new list, , doesn't manipulate original one. now let's have list of million elements , append 1 element @ end. haskell "copy" whole list (1 million elements) , adds element copy? or there neat "trick" going on behind scenes avoid copying whole list? and if there isn't "trick", process of copying large lists not expensive think is? it depends on data structure you're using. if you're using normal haskell lists, these analogous typical linked list implementation in c or c++. structure, appends o(n) complexity, while prepends o(1) complexity. if try append million elements, take o(500000500000) time (o(1) + o(2) + o(3) + ... + o(1000000)) approximately 500000500000 operations. regardless of language you're using, haskell, c, c++, python, java, c#, or assembler. however, if use structure data.sequence.seq , use

on watchkit, map component wkinterfacemap object. this ui component default, loads main map app on apple watch when user taps on it. i can keep track of controller's diddeactivate() event, have no idea if because user stopped using watch, tapped map or went somewhere else. unfortunately, there no method or event in watchkit determine if user tapped on wkinterfacemap . closest technique use diddeactivate , , you've enumerated challenges approach.

i created jwt token implementation based on taiseer's tutorial . the following code added owin startup class: oauthauthorizationserveroptions oauthserveroptions = new oauthauthorizationserveroptions() { allowinsecurehttp = httpcontext.current.isdebuggingenabled, tokenendpointpath = new pathstring("/oauth2/token"), accesstokenexpiretimespan = timespan.fromminutes(90), provider = new customoauthprovider(), accesstokenformat = new customjwtformat("http://example.com/") }; now there different types of apps use api. web clients, 90 minute expiration enough, mobile apps far short. is there way mobile apps token expiration 1 year now? use custom http headers differentiate between types of apps. tried extend expiration in protect method of customjwtformat class, indeed allows larger expiration in jwt. public class customjwtformat : isecuredataformat<authenticationticket> { public string protect(authenticationticket data) {

i have following task gulp.task('sass-build', ['clean-build'], function () { // stuff }); which requires clean-build finished before starting. however, use task gulp.watch without clean-build dependency. i'm aware solve helper task suggested in skipping tasks listed dependencies in gulp , require using gulp.run (which deprecated) or gulp.start (which isn't documented because it's considered bad practise). what better way of doing this? or way use gulp.run or gulp.start ? the approach showed in linked question not bad. instead of gulp.run can use simple functions same: var sassfunction = function() { return gulp.src('blahbla') .pipe(bla()) } gulp.task('sass-build', ['clean-build'], function () { return sassfunction() }); gulp.task('sass-dev', function () { return sassfunction(); }); gulp.task('watch', function() { gulp.watch('your/sass/files/**/*.scss'

recently, i've managed make custom listview in android displays image in list. however, have 1 problem cannot solve. tried simple, 1. display blinking icon list item has same date json data via web. 2. display image 2nd , 3rd position of listview. 3. , rest of list items, there no images shown. i have simple codition in custom adapter's getview method compares current date date gets retreived json data via web. i've set function i'm using below. if current date equal date json data, display image blinks(for testing purposes i'm using 2015/05/14). if position equal 2nd or 3 rd position display icon. else show nothing. however, images shows @ random positions of listview. there bug in code? how possible not show icons doesn't meet conditions ? if (days.get(position).trim().tostring().equals("2015/05/14")||days.get(position).trim().tostring()=="2015/05/14") { holder.left.setbackgroundresource(r.drawable.blinker); animationdr

i'm working on opening file using jfilechooser here code jfilechooser filechooser = new jfilechooser(); filechooser.setacceptallfilefilterused(false); filenameextensionfilter filter = new filenameextensionfilter("ff files", "ff"); filechooser.addchoosablefilefilter(filter); int result = filechooser.showdialog(null, "pp"); on button click event these code running, normal code guess. when click it, jfilechooser dialog appears. if enter directory name in file name field (ex. sam) , hit enter , enters directory, text field still shows entered text i.e 'sam' tried same flow in notepad , in eclipse, in phase, 'sam' getting cleared can provide directory name , hit enter. correct me if code wrong, if problem duplicate, apology wasted time. notepad , eclipse use different implementation jfilechooser . that´s why might behave different , don´t think can make work expecting (instead of using custom library or making own implem

i wondering if possible generate class, via annotation processor, inner class of class compiled. for instance, while compiling class a , generate class a$foo . wonder if there trick used or not. got feeling might possible generate source compiled in same byte code inner class would. and, @ compile/runtime, jvm take inner class, , allow accessing outer class private fields. the idea behind question, not noobie question, though may more or less technical, able use private visibility modifier annotated fields dagger, butterknife, etc. private modifier allowing detect unused fields more easily, whereas package private protection hides them. or there workaround, way best of both words ? given use case, no. an inner class normal java class, living in different .class file. when compiled, hidden constructor param added inner class constructor. private fields in outer class made accessible adding hidden accessor methods in outer class. of happens @ compile time. the jvm
