Mind Blowing Facts

edit i've got working now, i'm still not sure how did fixed it. if understands happening i'd love hear it. i'm making animated menu icon , it's working great...except middle bar's transition. it's supposed disappear using transition-delay after top , bottom bars come during first animation, , appear after top , bottom ones meet again second 1 (one third of way through in both instances). there no animation on middle bar, transition on background-color property. i've tried both shorthand transition , explicit transition-delay properties. both give exact same results. whole process works great in ie , firefox, fails in chrome , safari, makes me think it's possible webkit issue. i'm going post relevant code here (since there's 2 hundred lines whole thing). rest available @ codepen . if think should add more code let me know , add more. css: #menu label span.icon, #menu.lightbox label span.icon { height: 5em; widt...

i have array 3 integers. want duplicate array , change first integer. magical reason, both arrays first integer adjusted. have no idea why happening , it's driving me crazy. int [] numbers1 = {1, 2, 3} int [] numbers2 = {3, 4, 5} numbers2 = numbers1; at point did system.console.writeline see both arrays {1, 2, 3}. far good. numbers1[0] = 4; when i'm doing system.console.writeline see both arrays {4, 2, 3}. want numbers2 stay same. currently passing reference. numbers in array stored in memory. when reference object in memory points object. not create new object in memory when referencing, need clone ints array points different object in memory. numbers2 = numbers1; you need clone arrays. numbers2 = (int[])numbers1.clone(); as others have noted can use .toarray() method. creates copy of items in array. numbers2 = numbers1.toarray();

suppose define arrays visible gpu: double* doublearr = createcudadouble(fieldlen); float* floatarr = createcudafloat(fieldlen); char* chararr = createcudachar(fieldlen); now, have following cuda thread: void thread(){ int o = getoffset(); // same threads in launch double d = doublearr[threadidx.x + o]; float f = floatarr[threadidx.x + o]; char c = chararr[threadidx.x + o]; } i'm not quite sure whether correctly interpret documentation, , critical design: will memory accesses double, float , char nicely coalesced? (guess: yes, fit sizeof(type) * blocksize.x / (transaction size) transactions, plus maybe 1 transaction @ upper , lower boundary.) yes, cases have shown, , assuming createcudaxxxxx translates kind of ordinary cudamalloc type operation, should nicely coalesce. if have ordinary 1d device arrays allocated via cudamalloc , in general should have coalescing behavior across threads if our load pattern includes array index of form: data_array[...
