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

in ansible, code on remote machine, , want use result vars_prompt again on different host. i've searched around, , docs make sound should use {{ hostvars.local_server_name_in_vagrant_group.local_username }} , using example below set context. however, says index dictionary doesn't exist when referencing hostvars . instead, shown below, vars_prompt twice. gross! tips? btw, there's discussion on whether or not using vars_prompt great idea. have confirmed usage, indeed, want use vars_prompt. thanks! - hosts: vagrant vars_prompt: local_username: "enter desired local username" ... remote task activity using local_username... - hosts: localhost connection: local vars_prompt: local_username: "enter desired local username, again (please) ... host task activity, using local_username ... as said in comment question : you can use set_facts register variable fact of current host , access different one. not think standard

since rails 5 shipped action cable real time data transmission, i'm curious know more web sockets in ruby. i never worked socket in ruby know rails 4+ shipped actionlive real time data use case. but people using pusher-app real time data rails... could give brief idea actionlive vs pusher vs upcoming actioncable ? why pusher better actionlive? , how can take advantage that?

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[

hi have 2 tables same column . first need take 1 column value table 1 need search value weather exists in same column of table 2. can know how in spotfire? one way attempt join , perform logic on join results. below how this: create calculated column in table2 named exists expression of true . go insert>columns , choose add columns table1 table2. match on primary key (in case column "letter") select exists checkboxes add , use join method of left single match in order preserve number of records , hit finish. now have column named exists in table1 either null or true. if have true or false can create calculated column based upon evaluates if it's null or not so: [exists] not null . named mine "exists_tf" in example below. my data , resulting columns after above: you should able filter , calculations based on new column(s).
