i have small problem waiting response client. code looks this: num_bytes_received = recv(recvfd, line, max_line_size-1, 0); if(line[0] == 'r') { do_something(); } if(line[0] == 'p') { do_another_thing(); } is there simple way wait message let's 30 seconds , if there's no message execute do_another_thing(); function? it's not connection problems situation (like clients disconnect etc.). it's own limitation create. you can use select() timeout. int ret; fd_set set; struct timeval timeout; /* initialize file descriptor set. */ fd_zero(&set); fd_set(recvfd, &set); /* initialize timeout data structure. */ timeout.tv_sec = 30; timeout.tv_usec = 0; /* select returns 0 if timeout, 1 if input available, -1 if error. */ ret = select(recvfd+1, &set, null, null, &timeout)); if (ret == 1) { num_bytes_received = recv(recvfd, line, max_line_size-1, 0); if(line[0] == 'r') ...

very simple question: have pandas dataframe. 1 of columns looks this. date 2016-04-15 2016-04-14 2016-04-13 2016-04-12 2016-04-11 2016-04-08 how index of particular value assuming values unique. for example, "2016-04-13" return 2 use df.index.get_loc('2016-04-14') integer location requested label. return 1 intital starts 0 . can add 1 index value 2

i using mvc entity framework , gets following error. the specified cast materialized 'system.int64' type 'system.string' type not valid. error quite understandable , easy resolve , issue facing in sql query have plenty of columns, error details can't see column having specific issue , have go through columns 1 one. string query= "select id,claim_no,emp_id,dept_id,location_id staff"; var ctx = new tiaentities() ctx.database.sqlquery<orm>(query).tolist() i have viewed details in watch also, can't find column name. model:- public class orm { public int64 id { get; set; } public string claim_no { get; set; } public int64 emp_id { get; set; } public int64 dept_id { get; set; } public int64 location_id { get; set; } } you can use these solutions: var query = o in ctx.orm select new { id = o.id, ...

i'm supposed optimize code below make run atleast 16x faster using openmp , memory blocking. far can think of collapsing loops simple statement below. makes run 3 times faster. ideas on making closer 16? int i,j; #pragma omp parallel collapse(2) //my inserted code (i = 0; < msize; i++) (j = 0; j < msize; j++) d[i][j] = c[j][i]; when declare inner loop index in outer scope, must use private clause give each thread own copy. collapse may interfere simd vectorization.

in rails app, have number of js files available, , have placed them in app/assets/javascripts/globals , compiling them application.js via //= require_tree ./globals . however, have js files view specific, , prefer if implemented views or controllers. they're compiled in config/initializers/assets.rb via rails.application.config.assets.precompile += %w( foo.js bar.js ) , , accessed via <%= javascript_include_tag "foo/bar", "data-turbolinks-track" => true %> in respective views. i've wrapped essential functions in foo.js & bar.js in conditionals such if $("#foo").length > 1 ... , prevents functionality if required divs aren't present. as result, js files aren't "active" until after view visited. however, after being visited, js code "active" after visiting view. there control mechanism ensure js code being read correlating views? http://brandonhilkert.com/blog/page-specific-javascri...

i have simple datagrid has columns autogenerated , bound item source. item source updated @ intervals , can't find how fire event single cell changed. want change color of cell based on if update data source changed previous value of cell. i looked @ highlighting cells in wpf datagrid when bound value changes http://codefornothing.wordpress.com/2009/01/25/the-wpf-datagrid-and-me/ still unsure how go implementing this. example code helpful started on right path. if you're binding datatable, don't think productive path go down. doing kind of styling based on contents of datatable bound datagrid impossible in wpf. there several suggestions on stackoverflow, pretty hacky, event-driven (which bad news in wpf), , maintenance nightmare. if however, itemssource binding observablecollection, rowviewmodel class represents data in single row of datagrid, shouldn't bad. make sure rowviewmodel implements inotifypropertychanged, , update individual rowviewmodels...
