(this may odd, make list in python , .sort() it. that's order.) there undocumented class member, linearsvc().classes_ , holds order used class (see this method documentation ).

i got 3 fragments each on seperate tab. on 1 tab want have fragment in card-style. 1 row should [ ________ ________ +]. after pressing +button want second identical row appear. how achive that? professional way manipulate tagfragments during runtime? how can implement trancisions? i got it. can add additional rows by: @override public void onclick(view v) { switch (v.getid()) { case r.id.imagebuttonadd: if(i==0){ raisecounterbyone(); counter.settext(counterstart.tostring()); test = getactivity().findviewbyid(r.id.testview3); test.setvisibility(view.visible); i++; } else if(i==1){ raisecounterbyone(); counter.settext(counterstart.tostring()); test = getactivity().findviewbyid(r.id.testview4); test.setvisibility(view.visible); i++; } break; ...

say have nxn numpy matrix. looking fastest way of extracting square chunks (sub-matrices) matrix. meaning cxc parts of original matrix 0 < c < n+1 . sub-matrices should correspond contiguous rows/columns indexes of original matrix. want achieve in little time possible. you use numpy slicing, import numpy np n = 20 x = np.random.rand(n, n) slice_list = [slice(k, l) k in range(0, n) l in range(k, n)] results = [x[sl,sl] sl in slice_list] avoiding loops in numpy, not goal itself. long being mindful it, there shouldn't overhead.

i trying create mochajs test detect script.onload event has been executed or script.onerror. have setup tests detect script exists in dom not sure how check actual loading. describe("load external abc library", function() { var h = document.getelementsbytagname('head')[0]; var s = document.createelement('script'); s.src="http://host.com/script.js"; s.id="abc"; s.async=false; h.appendchild(s); var l = document.getelementbyid('abc'); it.skip("is in dom", function () { expect(l).to.not.equal(null); console.log('is in dom skipped'); }); it("is child of head", function () { expect(l.parentelement).to.equal(document.head); }); }); one way uses virtual dom via mocha-jsdom . example in coffeescript using mocha , chai , sinon , , sinon-chai : adddynamicscript.coffee: module.exports = (scriptname, callback) -> script = document.createelement 'scr...

i read below piece of information in microsoft article; https://support.microsoft.com/en-us/kb/44463 the text below presents example of common programming mistake, is, confusing array , pointer declaration: consider application divided several modules. in 1 module, declare array follows: signed char buffer[100]; in module, declare following variables access array: extern signed char *buffer; // fails extern signed char buffer[]; // works if view code in codeview debugger, indicates *buffer declaration produces different address buffer[] declaration does. but can't understand why cannot access array using *buffer , can access using buffer[] . someone please explain me difference between 2 types? see these questions in c faq list: http://c-faq.com/aryptr/aryptr1.html http://c-faq.com/aryptr/aryptr2.html http://c-faq.com/aryptr/aryptrparam.html

i've created lower triangular distance matrix (because of size issues) jagged array note: distances between objects symmetric var dm = new double[size][] (var = 0; < size; i++) { dm[i] = new double[i+1]; (var j = 0; j < i+1; j++) { dm[i][j] = distance(data[i], data[j]); } } i need access matrix made following method it private double getvalueofdm(int row, int column, double[][] dm) { return column <= row ? distancematrix[row][column] : distancematrix[column][row]; } with visual studio performance analysis 1 sees major speed issue lies in row of getvalueofdm method. has idea how speed up? you remove conditional in method , increase memory usage increase access performance so: var dm = new double[size][]; (var = 0; < size; i++) { dm[i] = new double[size]; (var j = 0; j < i+1; j++) { dm[i][j] = distance(data[i], data[j]); dm[j][i] = dm[i][j]; } } private double getvalueofdm(int row, int column, ...

i have several areas in game project split on several scenes, instance let's there first area called "basement" split in basement_1, basement_2 , basement_3 scenes; , area, "attic", split on attic_1 , attic_2. some assets (textures atlas , sounds) shared across scenes of area , thought make assetbundle shared assets "basement", , assetbundle shared assets "attic" area. when player enter "basement" area, i'd load "basement" assetbundle, when call application.loadlevel("basement_1"), application.loadlevel("basement_2") or application.loadlevel("basement_3"), shared assets (which have been loaded in bundle) aren't unnecessarily reloaded, scene-specific assets loaded. if point game knows basement assets no longer necessary, or not long time @ least, i'd unload bundle, free memory, , load whatever other bundle may relevant (the attic 1 instance). my question is: how works? in, i...
