while developing android application, attention caught backing array . multiple strings can share same char[] because strings immutable. substring(int) method returns string shares backing array of source string. optimization: fewer character arrays need allocated, , less copying necessary. can lead unwanted heap retention. taking short substring of long string means long shared char[] won't garbage until both strings garbage. typically happens when parsing small substrings out of large input. avoid necessary, call new string(longstring.substring(...)). string copy constructor ensures backing array no larger necessary. then have read many resources on web. know strings no longer shares same backing array since jdk7u6 , pointed mark rotteveel . then started trying play with, , test existence of shared backing array in code: string str = "1234567890"; system.out.println("str.substring(1): " + (str == str.substring(1))); system.out.println(&quo

i having major problem getting started finding answer question? have uitableview being populated user generated content , being persisted coredata. good. can't find way in apple docs following: how add each dollar value in cell grand total displayed somewhere user? in case can thrown in uilabel in footer of each section don't care. can't figure out how each individual cell dollar amount entered there , add next dollar amount in next cell in section , on. any ideas on how add totals cells grand total? the elegant solution problem using key paths. you not go cells , data out. go data model , calculate there. remember, mvc dictates should separate model , view. suppose have subclass of nsmanagedobject nsnumber attribute "amount" fetched via core data. can simple calculations this: float sum = [[fetchedobjects valueforkeypath:@"@sum.amount"] floatvalue]; this described in key-value coding programming guide under collection operators

i understand in generic programming, algorithms decoupled containers. make no sense implement generic algorithm instance method (the same algorithm should work on multiple concrete classes; don't want make them inherit 1 abc since exponentially increase number of classes). but in case of source() function in boost graph library , don't understand why global function , not instance method of graph class. as far tell reading bgl source code , source(e, g) needs know implementation details of graph , edge objects passed it; it's not enough know interfaces . so source() not generic algorithm. in other words, needs know concrete class of graph instance. why not put in same class instance method? wouldn't lot cleaner / less confusing making global function needs customized each class it's called upon? update the relevant source code: // dwa 09/25/00 - needed more explicit reverse_graph work. template <class directed, class vertex, class ou

the 2 answers on here involve restructuring database accommodate limitation, unsure how in case. i have list of thousands of contacts, each many many properties. i'm making page has ability filter on multiple properties @ once. for example: age < 15, date added > 15 days ago, location == santa cruz, etc. potentially ton of inequality filters required. how 1 achieve in gae? according the docs (for python) , limitations: datastore enforces restrictions on queries. violating these cause raise exceptions. for example, combining many filters, using inequalities multiple properties, or combining inequality sort order on different property disallowed . filters referencing multiple properties require secondary indexes configured. if check in few months, may change. gae keeps changing pretty quickly. for now, though, you'll have make multiple queries , combine them in code.

i'm using scipy instead of matlab in control systems class plot step responses of lti systems. it's worked great far, i've run issue specific system. code: from numpy import min scipy import linspace scipy.signal import lti, step matplotlib import pyplot p # create lti transfer function coefficients tf = lti([64], [1, 16, 64]) # step response (redo better resolution) t, s = step(tf) t, s = step(tf, t = linspace(min(t), t[-1], 200)) # plotting stuff p.plot(t, s) p.xlabel('time / s') p.ylabel('displacement / m') p.show() the code as-is displays flat line. if modify final coefficient of denominator 64.00000001 (i.e., tf = lti([64], [1, 16, 64.0000001]) ) works should, showing underdamped step response. setting coefficient 63.9999999 works. changing coefficients have explicit decimal places (i.e., tf = lti([64.0], [1.0, 16.0, 64.0]) ) doesn't affect anything, guess it's not case of integer division messing things up. is bug in scipy, or doi

i need assign static data- attribute ember.view, how set in view object instead of in {{view }} tag. app.messagesformview = ember.view.extend({ tagname: 'div', classnames: ['modal', 'fade'], didinsertelement: function() { this.$().modal('show') }, willdestroyelement: function() { this.$().modal('hide') }, }) unfortunately, don't have enough reputation comment on ola's answer, believe better way not use string (text in quotation marks) denote data attribute property name. instead, write property name in camelcase , ember automatically bind hyphenated attributebinding. example: app.messagesformview = ember.view.extend({ tagname: 'div', attributebindings: ['data-backdrop'], databackdrop: 'static', // binds data-backdrop. awesome! }); i hope makes sense!

i stuck casting issue converting byte string byte array. i.e have string " [b@1a758cb ". base64 encrypted string of main string "gunjan". here decryption want convert encrypted byte string byte[]. but string.getbyte[] not working me. string.getbytes[] gives bytes of byte string. how can ?? have iterate on each character in byte string , convert them byte[] ?? edited i using apache coded 3.1 jar base64 conversion. here code getting encrypted text.. string in = "gunjan"; byte[] bytestr = in.getbytes(); byte[] base64encoded = base64.encodebase64(bytestr); here value of base64encoded [b@1a758cb can see console log in image.. first of all, don't have problem here, since decoded string value (gunjan) equal original value (gunjan). you're confused printed intermediate byte arrays. noted in comments, strings [@bxxxx result of calling tostring() on byte array. desn't display value of bytes, type of array ( [@b ) followe

i'm not sure why happening. have read explanations on here can't seem find myself. on both series , episodes lists site missing first row when echoing results. fix great. here's coding episode page <?php include '../connect/dbseries.php' ?> <?php $result2 = mysql_query("select seriesid, seasonindex, sortname, thumbfilename, currentbannerfilename, posterbannerfilename, summary, imdb_id, episodename, episodeindex, compositeid series seriesid = '$_get[id]' order seasonindex, episodeindex asc;"); if (!$result2) { echo 'could not

what mysql script means time between ? adddate(curdate(), -(day(curdate())-1)) , concat(last_day(curdate()),' 23:59:59') day(curdate())-1 current day of month, less 1. today (aug 15, 2013), value 14. subtract 14 days august 15 , have august 1. in other words, adddate(curdate(), -(day(curdate())-1)) gives first day of month. last_day(curdate()) gives last day of month. if call today return august 31, 2013. append 23:59:59 , have last second of last day of month. in other words, if called on august 15, 2013, values come out 2013-08-01 , 2013-08-31 23:59:59 . if range applied against datetime value, means "anything in month of august 2013". this pretty way check date/time values within month because avoids using function on mysql column holds date/time. if column has index, index (probably) used optimization. 1 approach see this: where date_format(mydatetime, '%y%m') = date_format(curdate(), '%y%m') this reads little be

is there way in c store whole command line options , arguments in single string. mean if command line ./a.out -n 67 89 78 -i 9 string str should able print whole command line. now, able print values in different vector forms. #include <stdio.h> #include <getopt.h> #include <string.h> int main(int argc, char* argv[]) { int opt; for(i=0;i<argc;i++){ printf("whole argv %s\n", argv[i]); } while((opt = getopt(argc, argv, "n:i")) != -1) { switch (opt){ case 'n': printf("i %s\n", optarg); break; case 'i': printf("i %s\n", optarg); break; } } return 0; } i want this, optarg printing first argument , want arguments printed, want parse after storing in string. simply write function this: char * combineargv(int argc, char * * argv) { int totalsize = 0; (int = 0; < argc; i++) { totalsize += strlen(argv

i've got observablecollection in viewmodel need modify in code on background thread (using task object). i've got icollectionview attached collection. when modify collection @ run-time, code runs fine. in unit testing error, "this type of collectionview not support changes sourcecollection thread different dispatcher thread." i create collection thusly (on ui thread @ run-time): cashdeliverydepots = new observablecollection<cashdeliverydepot>(); filteredcashdeliverydepots = collectionviewsource.getdefaultview(cashdeliverydepots); and modify using code (which running on non-ui thread @ run-time): currentdispatcher.invoke(() => { foreach (var depot in depots) { cashdeliverydepots.add(depot); } }); the currentdispatcher class executes code according whether or not there application dispatcher. internal static class currentdispatcher { internal static void invoke(action action) {

i have set of images on amazon s3, , i'd automatically generate thumbnails them serve on site. i've considered cloudinary, seems i'd have copy on images cloudinary servers first. want keep them on s3. i've considered dragonfly, seems dragonfly works files i'd upload after installing dragonfly. have uploaded files. what's solution me? i'm in rails environment (rails 3.2). thanks! if it's 'set of images' it's not structured. you're better off reorganizing way store , manage images. try paperclip . class modelname < activerecord::base attr_accessible :image #more here has_attached_file :image, :styles => { :large => "450x450>", :medium => "300x300>", :thumb => "150x150>" }, :storage => :s3, :s3_credentials => "#{rails.root}/config/s3.yml", :path => "people/:style/:id/:filename", :s3_protocol => "https"

i have duplicate rows in table, how can delete them based on single column's value? eg uniqueid, col2, col3 ... 1, john, simpson 2, sally, roberts 1, johnny, simpson delete duplicate uniqueids 1, john, simpson 2, sally, roberts you can delete cte: with cte (select *,row_number() over(partition uniqueid order col2)'rowrank' table) delete cte rowrank > 1 the row_number() function assigns number each row. partition by used start numbering on each item in group, in case each value of uniqueid start numbering @ 1 , go there. order by determines order numbers go in. since each uniqueid gets numbered starting @ 1, record row_number() greater 1 has duplicate uniqueid to understanding of how row_number() function works, try out: select *,row_number() over(partition uniqueid order col2)'rowrank' table order uniqueid you can adjust logic of row_number() function adjust record you'll keep or remove. for instance,

edited after reading further, modified question more specific. as per microsoft documentation : an expression evaluates true if provided expression non-null, , provided object can cast provided type without causing exception thrown. otherwise, expression evaluates false. here issue below. var test = (int32)(int16)1; // non-null , not cause exception. var test2 = (int16)1 int32; // evaluates false. the documentation states: note operator considers reference conversions, boxing conversions, , unboxing conversions. other conversions, such user-defined conversions, not considered. so, i'd assume doesn't work above because user-defined conversion. how check see if castable type including non-reference/boxing/unboxing conversions? note: found issue when writing unit tests casttoordefault extension works on types, including non-reference types (as compared as ). refactored answer based on mike precup's linked code i cleaned answer bec
