why code (or similar) var http = require('http'); var async = require('async'); async.forever(function(next) { http.get('http://google.com', function(res) { next(); }); }); executing 5 times latest released node (0.10.28)? by default, node sends http requests connection: keep-alive header set, connection not closed after 1 request. , default maximum number of concurrent connections same server:port set 5. controlled http.globalagent.maxsockets property. it's mentioned in documentation it's hard find if don't know or don't read through docs. also, these classes being rewritten , next releases have different behaviour.

i'm new nvd3 charts. need line chart, string-values on x-axis chart should bar chart , need line, instead of bars my result looks line chart values mapped x=0 my code nv.addgraph(function() { var chart = nv.models.linechart() .useinteractiveguideline(true) .transitionduration(350) .x(function(d) { return d.x}) .y(function(d) { return d.y}) .showlegend(true) .showyaxis(true) .showxaxis(true); chart.xaxis.tickvalues(["monday", "tuesday", "wednesday", "thursday", "friday", "saturday", "sunday"]); d3.select(element + ' svg') .datum(data) .call(chart); nv.utils.windowresize(chart.update); return chart; }); and data [{"color":"#a215af","key":"products","values":[ {"label":"monday","y":0,"x":"monday"}, {"label":"t...

i supposed declare structure holds name , grades of unknown number of students. here how did it: struct student { char name[30]; int grade1, grade2, grade3; }; then, have text file containing information each student on different lines. read way. student info[20]; int nr_students,i=0,k=0; fstream infile; infile.open("in.txt"); fstream outfile; outfile.open("out.txt"); while(!eof) { infile>>info[i].name; infile>>info[i].grade1; infile>>info[i].grade2; infile>>info[i].grade3; i++; } nr_students=i; avg_promovability(outfile,info, nr_students); i not think works properly, since nr_students remains 0, apparently. also, first function: void avg_promovability(fstream &outfile,student *info, int nr_students) { int i; float sum=0,j=0,avg; (i=0;i<nr_students;i++) if(info[i].grade1 >=5 && info[i].grade2>=5 && info[i].grade3>=5 ) { sum=sum + info[...

i know in javascript maximun , minimun safe numbers of precision 16 (tested in chrome): number.max_safe_integer → 9007199254740991 number.min_safe_integer → -9007199254740991 however number.prototype.toprecision() allows numbers greater 16, until 21. in range results wierd (wierd = don't understand right now): 6.789.toprecision(21) → "6.78899999999999970157" /*¿why "70157" ending in chrome(34.0.1847.137) , firefox(29.0.1)?*/ 2.345.toprecision(21) → "2.34500000000000019540" /*¿why "19540" ending in chrome , firefox?*/ ie11(11.0.99) returns expected: 6.789.toprecision(21) → "6.78900000000000000000" 2.345.toprecision(21) → "2.34500000000000000000" ¿is bug in javascript engines of chrome(v8) , firefox(spidermonkey)? ¿is ie11 javascript engine (chakra) better in it's number.prototype.toprecision() interpretation?
