can recommend way reverse cumulative sum on numpy array? where 'reverse cumulative sum' defined below (i welcome corrections on name procedure): if x = np.array([0,1,2,3,4]) then np.cumsum(x) gives array([0,1,3,6,10]) however, get array([10,10,9,7,4] can suggest way this? this it: np.cumsum(x[::-1])[::-1]

ok, pretty sure weird behaviour - , have no idea going on... code below. i running jasmine spec on possibly simple angularjs controller ever, makes call function (getsuppliers) upon initialisation, in turn makes http request, have mocked out using $httpbackend. weirdness happens when run test. fails expected undefined equal 'list of suppliers' . so stuck in debugger; s (1 , 2) , ran spec in chrome. weird part. debugger 2 gets hit before debugger 1, meaning getsuppliers function returns value of undefined before mock has chance it's magic. record, when continue on , let debugger 1 come well, data has correct value of "list of suppliers" , if mock run in right place should sweet. have idea hell going on here? spec.js describe("supplier controller", function(){ ctrl = null; scope = null; httpbackend = null; suppliercontroller = null; beforeeach(inject(function($controller,$rootscope,$httpbackend) { scope = $rootsc...

i'm making program has 4 players taking turns tossing 3 coins. first player earn 16 points wins. player earns points each time tosses coins. number of points earns equals number of heads tosses. if tosses no heads loses next turn . if flips 3 heads earns turn , tosses coins again. if tosses less 3 heads next player’s turn. player must earn 16 points win. if player has 14 points , tosses 2 heads wins if tosses n heads , goes on 16 points loses half of points , loses turn too. must have 16 points win. how player skipped next turn? each player goes in order. ex. tom, hank, hannah, tina. if hank rolls 0 heads or goes on 16 points should lose next turn making order tom, hannah, tina, tom, hank, hannah, tina. i've posted code , need figure out how edit nextplayer() method suit needs. believe logic , code did in computerstate() method correct lose_turn. appreciated. game class import java.util.random; public class game { private random randomizer; priva...

for android, each application has own instance of dvm or each activity of application has own dvm instance i.e. instance of dvm created based on application or activity? generally, each process has own dalvik vm. since each application runs in single process, activities share dalvik vm process. there more complicated scenarios (one app spread across n processes, n apps sharing 1 process), unusual in conventional android application development.

i need log info file around 1000-2000 times minute. need save info in case app crashes. currently here's i'm doing: using(streamwriter sw=new streamwriter(filename,true)) { sw.writeline(info); } this works, it's extremely slow. i'd doing this: static streamwriter sw=new streamwriter(file,true); .... public static void main(...) { ..... sw.writeline(....); } but when write code this, i'm afraid info store lost when app crashes. what can preserve info in file without having open , close time? you can call streamwriter.flush() after each write. public static void main(...) { ..... sw.writeline(....); sw.flush(); } but should use nlog or log4net !

i have tried close photoswipe screen gallery using history.go(-1); takes me previous screen gallery was. how can close photoswipe screen gallery using code staying in page call gallery? in advance. i managed line: window.code.photoswipe.activeinstances[0].instance.hide();

i saw example here : val fut = future { ... // body function } // body function starts here fut oncomplete { ... // callback } looks may add callback after completion of body function. still invoked ? anyway, prefer add callbacks future before function starts running. make sense ? how can ? if want control point of execution of future, chain promise . import scala.concurrent._ import executioncontext.implicits.global val initialpromise = promise[unit] // add computations val fut = initialpromise.future map { _ => println("my future") } // register callbacks fut oncomplete { _ => println("my callback") } // run initialpromise.success() using other unit allows feed computation arbitrary values.

i'm sort of making 'web parser', except 1 website, parsing many different pages @ 1 time. currently, there may 300,000 pages need parse, in relatively fast manner (i'm grabbing tiny amount of information doesn't take long go through, every page takes ~3 seconds max on network). of course, 900,000 seconds days = 10 days, , terrible performance. reduce couple of hours @ most, i'm reasonable time amount of requests, still needs 'fast'. know can't 300,000 @ 1 time, or website block of requests, there have few seconds delay in between each , every request. i have processing in single foreach loop, not taking advantage of multithreading ever, know take advantage of it, i'm not sure path should take whether threadpools, or type of threading system or design. basically, i'm looking point me in right direction of efficiency using multithreading can ease time take parse many pages on end, sort of system or structure threading. thanks ...

i'm trying avoid following pattern in .gitignore file. myprject/webapp/scripts/special/*.js myprject/webapp/scripts/special/*/*.js myprject/webapp/scripts/special/*/*/*.js myprject/webapp/scripts/special/*/*/*/*.js myprject/webapp/scripts/special/*/*/*/*/*.js myprject/webapp/scripts/special/*/*/*/*/*/*.js myprject/webapp/scripts/special/*/*/*/*/*/*/*.js we tried: myprject/webapp/scripts/special/**.js myprject/webapp/scripts/special/**/*.js this didn't work. git on windows. there more concise way without repeating things? as of git 1.8.2, this: myprject/webapp/scripts/special/**/*.js should work according this answer . works me in windows 7 using sourcetree 1.6.12.0 , version of git installs (1.8.4-preview20130916). to gitignore every file , folder under directory recursively: myprject/webapp/scripts/special/**

please see following jsfiddle: jsfiddle link my jquery: $('.tr1').addclass('addborder'); $('.tr2').removeclass('removeborder'); $('#bname').click(function() { $('.tr1').addclass('addborder'); $('.tr2').addclass('removeborder'); }); $('#bspecialty').click(function() { $('.tr2').addclass('addborder'); $('.tr1').addclass('removeborder'); }); it suppose make name row have double blue border , based on user selection radio button should make row have blue border , remove border row not selected. it's not working reason. i tried toggleclass(); removes existing class, won't work user should able click on same radio button multiple times , class should not change. should change if other radio button clicked. you should add border table cell not row. don't need add 2 different class.. instead can addclass adds border , removeclass ...

i'd find radio buttons on form , leave other input types alone. code looks this: form.queryall("select, input").foreach((element el) { if (el radiobuttoninputelement) { print ('got radio button'); } else { print ('got other input type'); } } this results in input types other select being identified radio buttons. in fact, if @ el in then branch ("got radio button"), reported inputelement . you write query selector return radio buttons. list<radiobuttoninputelement> list = element.queryselectorall("input[type='radio']");

i'm in trouble such issue: need select area rect on label, i'm using qrubberband this, there 1 problem: need know coordinates of current rect on label, i'm in trouble it, because mouseevent->pos() give coordinates starts top left corner on mainwindow border, i've rotate standard coords on label (from top left bottom left corner, paint them usually). anybody knows how can translation? qpoint mappedpos = mylabel->mapfromparent(mywindow, mouseevent->pos()); also, qtransform provides number of map() functions should able point in rotated coordinates well. see: qwidget::mapfromparent() qtransform::map()

how can same result using activerecord? select categories.* categories inner join levels on levels.id = categories.level_id levels.description <= "medium" it's hard precise without more details, should that: category.joins(:level).where('levels.description <= "medium"') i think should trick: category.joins(:level).where(level.arel_table[:description].lteq('medium'))
