i'm reviewing reactjs, following tutorial @ https://facebook.github.io/react/docs/tutorial.html , when playing example run weird behavior. problem content of 1 element (the comment) doesn't refreshed . instead duplicates new data. see working fiddle @ http://jsfiddle.net/l0xy4jqa/2/ what's wrong? code: /* html */ <script src="http://fb.me/react-js-fiddle-integration.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/marked/0.3.2/marked.min.js"></script> <div id="content"></div> /* js */ var data = [ {author:"mr. raspa pan", color:"darkblue", text: "- content"}, {author:"mrs. pasa sa", color:"darkgreen", text: "- *other* content"}, {author:"mrs. rata tan", color:"brown", text: "- __more__ content"}, {author:"mr. aspa spa", color:"deeppink", t

i want split array pairs of arrays so var arr=[2,3,4,5,6,4,3,5,5] would newarr =[[2,3],[4,5],[6,4],[3,5],[5]] there's no pre-baked function that, here's simple solution: var splitpairs = function(arr) { var pairs = []; (var i=0 ; i<arr.length ; i+=2) { if (arr[i+1] !== undefined) { pairs.push ([arr[i], arr[i+1]]); } else { pairs.push ([arr[i]]); } } return pairs; };

i have redis cluster of 3 master nodes , 3 slaves. have 3 sentinel servers (each on separate machine) monitoring redis cluster. using predis, able connect cluster via single master node's ip/port. want know if can connect predis cluster via sentinel ip/port? redis cluster handles failover without sentinel, don't need use sentinel via redis cluster. only thing need choosing library can support redis cluster.

can tell me there way in elasticsearch/kibana provide pivoting feature in oracle? i want create report pivoting field sum aggregation. for example : have schema indexed in test-index/test-type doc id being id . id | name | code | amt ----------------------- 1 | abc | | 10 2 | def | c | 20 3 | xyz | | 30 4 | abc | | 10 5 | abc | c | 20 6 | xyz | b | 30 7 | def | c | 10 8 | def | | 20 i want generate report pivoting done : sum(amt) code in (a,b,c) name | | b | c --------------------- abc | 20 | 0 | 20 def | 20 | 0 | 30 xyz | 30 | 30 | 0 can using elasticsearch , reports generated in kibana? ps. new elasticsearch query dsl, helpful if having grasp on query dsl can me out whether possible in es , or suggest me way this??

i want move header locations top(columns) , left(rows) right(rows) , bottom(columns). can find information aliments content within headers, not alignment of headers themselves. see photo below example of this... i know might tricky add items accordingly datagridview, data needs organized way opposed headers on top , left. (if using datagridview hard, there object can use?) as always, thanks! afaik, not possible in winforms. don't know how in wpf , don't know other out-of-the-box solutions. my proposal: cheat adding dgv on right , 1 on bottom. contain headers. need 'connect' scrolling events of dgvs. got idea i'm meaning? not nicest solution , sure bit tricky, one.

interview questions start "this might solved generating possible combinations array elements" meant let me find better. anyway add "i prefer solution since o(x)".. question is: o(x) complexity of generating combinations given set? i know there n! / (n-k)!k! combinations (binomial coefficients), how big-o notation that? first, there nothing wrong using o(n! / (n-k)!k!) - or other function f(n) o(f(n)) , believe looking simpler solution still holds same set. if willing @ size of subset k constant, for k<=n-k: n! / ((n-k)!k!) = ((n-k+1) (n-k+2) (n-k+3) ... n ) / k! but above (n^k + o(n^(k-1))) / k! , in o(n^k) similarly, if n-k<k , o(n^(n-k)) which gives o(n^min{k,n-k})

how kernel developers test changes on specific hardware? if don't have particular type of hardware, how figure out issue happening? generally, kernel developers responsible writing drivers specific piece of hardware happens tester , owns piece of hardware. if developer comes across bug (or if people report bug) on piece of hardware, 1 fixes it. it'd silly ask fix or maintain driver hardware not own. as higher level kernel features, here linux development paradigm comes play. linux employs merge window strategy releasing since it's unrealistic ask every developer test changes on every single possible combination of hardware , software combinations. instead, after major release, merge window opened around 2 weeks developers can push in significant changes, new drivers , features. after merge window closes, no more patches new changes accepted. during time merge window closed, developers have chance test newly merged code on own hardware , report bugs , br
