jmeter user manual says: jmeter not browser. jmeter not execute javascript found in html pages. i wanted know exact meaning of statement. most perhaps every webpage have javascripts included. taking example of testing single page (say home page), , usual page have number of js, css, images. during recording, recorded embedded resources. far knowledge, before running test in jmeter, have following 3 options 1. take top level request (homepage.html) without selecting embedded resources check-box 2. take top level request (homepage.html) along selecting embedded resources check-box 3. keep top level request along other components recorded which among 3 best option check page load time (i assuming 1st option, tries replicate close browser) and otherwise, if jmeter not execute javascript, how getting response of js file? jmeter won't execute javascript , won't render page, download .js file , record , replay ajax call driven javascript. so suggest going opti

when started working git based workflow on gitflow model: http://nvie.com/posts/a-successful-git-branching-model/ . thought main idea keep commits appropriate branches; example main branch have commits had been merged in development branch ... ie tags ... 0.1. 0.2. 1.0 in graphic. don't understand how git works or how workflow meant operate that's thought, since graphic on page shows these few commits on master branch, not development ones well. i push repo bitbucket , went while working in development branch, when finished development; , and pushed master branch found master branch in bitbucket contains of commits made on development branch, whereas thought contain last commit ( 1 merged in). can explain why this, , whether intended behaviour, , if not can workflow working in line model above. use smartgit. your branching model seems require specifying --no-ff on every merge, forcing bookkeeping entries empty merges -- example in graphic you'd merge hotfixe

is possible delete between tables? something like... delete bd between table1 , table 10 vehicle 761 delete bd.table_1 id_vehicle=761 delete bd.table_10 id_vehicle=761 you can either write stored procedure (look @ mysql dynamic query in stored procedure ) or change table structure either vehicle ids related via foreign key constraint (then can cascading deletes, see http://www.mysqltutorial.org/mysql-on-delete-cascade ), or use 1 big table store everything, partition date, if content reaches size, makes sense.

i'm noob who's written js code google maps , facing problems. what i'm trying achieve:- when page loads, picks location. when click on map, drops marker. when click somewhere else, drops same marker on different location now. gets co-ords of place , displays in text box. conversely, add location in address bar , if present, drops marker location , gets co-ords. problems facing: the map drops new marker everytime click on map. doesn't co-ords of location. does not search address. my limitations: noob cannot figure out code search address bar. please point me in right direction. here's code function initmap() { var map = new google.maps.map(document.getelementbyid('map'), { zoom: 8, center: {lat: 40.731, lng: -73.997} }); google.maps.event.addlistener(map, 'click', function(e) { placemarker(e.latlng, map); }); function placemarker(latlng, map) { var marker = new google.maps.marke

i reading this editorial , got confused statement: if array elements non-negative, can use binary search find answer in o(n log s) time, s maximum sum of subarray." can explain above statement. assume have array sum , @ index ith store sum of element 0 ith , so, if element non-negative, sum[0] <= sum[1] <= sum[2] ... <= sum[i] ... <= sum[n - 1] we notice that, sum of sub array (i, j) of array a sum[j] - sum[i - 1] so, given number x, can calculate rank of number sum of sub array of follow: int rank = 0; for(int = 0; < n; i++){ int index = minimum index sum[i] - sum[index] >= x; //as sum[0] <= sum[1] <=... , can use binary search find index rank += index; } finally, find number kth number, can use binary search in range o s , use above algorithm calculate rank, s maximum sum of subarray. int start = 0; int end = s; while(start <= end){ int mid = (start + end) >> 1; int rank = calrank(mid , su

i'm trying find way query huge table graph statistics. here's how i'm forming graph data. day on x-axis , amount y-axis. select date_format(earning_created, '%c/%e/%y') day, count(earning_link_id) amount earnings earning_link_id = 1093 group date(earning_created) took 21.8s....earnings has 550,000 rows. i'm in process of setting read replica server, brute force, not elegant query approach. i wonder how can optimize type of query, can graph data quickly? as suggested in comments, table may lacking of index. the obvious earning_link_id it's column used in where condition. as side note when have performance issues on requests and/or want optimize them, use explain , explain extended . show how mysql scans table answer query. if table has no index filtered columns ( where condition ) scan rows costly; whereas index on earning_link_id mysql don't need scan whole table find affected rows ( for query ).

answer given : 1000 i don't understand side it's many-one relation , side it's one-one relation. there many er diagramming conventions, , haven't explained or given reference yours. included expressing cardinalities, , in particular cardinalities n-ary relationships n > 2. googling text of question: diagram appears in (different) question in this solution says of diagram: (i) unique pair (a,b) there can unique value of c in relationship set r , and (ii) unique pair (a,c) there can unique value of b in r . so seems arrow indicates target entity appears once a given appearance of combination of others in relationship set. there's @ 1 c per (a,b) pair; every {a,b} pair unique in set. there @ 10*100 entities. there's @ 1 b per (a,c) pair; every {a,c} pair unique in set. there @ 10*1000 entities. from both those, know there @ 1000 entities. there 10*100 entities, since each possible (a,b) pair appear in set each different c

if example have 3 expressions: a , b , c follows: a(i+1) = a(i) + c(i).k b(i+1) = b(i) + a(i).h c(i+1) = a(i) + b(i) where k , h constants , m , n desired size of c . i previous obtained value, i+1 next value. now, if use for loop, can code as: a(1)= 2; b(1)= 5; c(1)= 3; i=1:10 a(i+1) = a(i) + c(i)*2; b(i+1) = b(i) + a(i)*3; c(i+1) = a(i) + b(i); end and works fine. want code in vector form , in without having use loop. problem not know how around dependency of: a on previous value , previous c value b on previous values , previous c value of a c on previous values of a , b here's matrix-based way obtain n -th value of [a;b;c] vector. wouldn't call vectorization, speed things considerably you: [a,b,c] = deal(zeros(11,1)); a(1)= 2; b(1)= 5; c(1)= 3; %% // original method k=1:10 a(k+1) = a(k) + c(k)*2; b(k+1) = b(k) + a(k)*3; c(k+1) = a(k) + b(k); end %% // matrix method: %// [ ] [1 0 2][ ] %// | b | = |3 1
