i want suppress notices in codeigniter error log during cronjob. i've tried using @ in front of line, still prints notice in log: this row generating notice: @$resultarray[1][2]++; the notice: ... severity: notice --> undefined offset: 1 ... what doing wrong here? (i'm using overthought, please no messages claiming not use @, :) ) to have php report errors except e_notice, call php error_reporting function so: error_reporting(e_all & ~e_notice); i believe best way configure index.php @ root of application first detect application environment , conditionally set php errors reported. index.php if (defined('environment')) { switch (environment) { case 'development': case 'testing': case 'staging': error_reporting(e_all & ~e_notice); break; case 'production': error_reporting(0); break; default: exit('the application environment not set correctl

can explain why postgresql works so: if execute query select * project_archive_doc pad, project_archive_doc pad2 pad.id = pad2.id it simple join , explain looks this: hash join (cost=6.85..13.91 rows=171 width=150) hash cond: (pad.id = pad2.id) -> seq scan on project_archive_doc pad (cost=0.00..4.71 rows=171 width=75) -> hash (cost=4.71..4.71 rows=171 width=75) -> seq scan on project_archive_doc pad2 (cost=0.00..4.71 rows=171 width=75) but if execute query: select * project_archive_doc pad pad.id = ( select pad2.id project_archive_doc pad2 pad2.project_id = pad.project_id order pad2.created_at limit 1) there no joins , explain looks like: seq scan on project_archive_doc pad (cost=0.00..886.22 rows=1 width=75)" filter: (id = (subplan 1)) subplan 1 -> limit (cost=5.15..5.15 rows=1 width=8) -> sort (cost=5.15..5.15 rows=1 width=8)

i have structure, need initialize @ compile time. here current (pseudo)code: struct { int a; int b; }; struct b { struct а[16][3]; }; #define default {{ \ .a = 1, \ .b = 2, \ }, \ { \ .a = 3, \ .b = 8, \ }, \ { \ .a = 11, \ .b = 29, \ }} #define default2 default, default #define default4 default2, default2 #define default8 default4, default4 #define default16 default8, default8 struct b b = {{default16}}; i don't understand code: why need double braces on last line? moreover, why need double braces in definition of default. understand { .a = 3, .b = 8, } is ordinary structure initialization. second pair of braces seems if initializing b array of 16 objects of type struct [3] . why not list values

i need calculate ex_vat echo result need calculate inc_vat echo result. it needs rounded 2 decimal places. basically doesn't work, calculation nothing displays: £29.17 inc vat £29.1700 ex vat i don't know proper syntax this, why i'm asking on here, thanks! code: $req4 = $con->query("select price, vat_rate product product_id='$prodid'"); $row4 = $req4->fetch_row(); $price_ex_vat = $row4[0]; $vat_rate = $row4[1]; $price_inc_vat = 0; $price_inc_vat = $price_ex_vat + ($price_inc_vat * $vat_rate / 100); in line $price_inc_vat = $price_ex_vat + ($price_inc_vat * $vat_rate / 100); you calling variable "$price_inc_vat" not existing yet. may want assign value variable before using it. like $price_inc_vat = 29.17; $price_inc_vat = $price_ex_vat + ($price_inc_vat * $vat_rate / 100); now round 2 decimal places ff: $price_inc_vat = 29.17; $price_inc_vat = $price_ex_vat + ($price_inc_vat * $vat_rate / 100); $price_

i trying load map in second section of page http://lowcoupling.appspot.com/anothermappage.html as can see problem map depicted 1px line what doing wrong? what doing wrong? you using height:100% make map high section - calculate min-height: calc(100% - 1px); . have bootstrap row element between, which not have set height , map not have a direct parent element calculate it's width from - takes 1px - set default bootstrap ( min-height:1px - keep columns in place). you need have direct parent element has set height (that not defined in percentages) have map expand 100% of it's height. if row element wraps map have fixed height, map container expand 100% of height. see example direct parent using calc(100% - 1px) : http://jsfiddle.net/ldzsk/1/

this question has answer here: does new[] call default constructor in c++? 3 answers i need create bool array unknown length passed parameter. so, have following code: void foo (int size) { bool *boolarray = new bool[size]; (int = 0; < size; i++) { if (!boolarray[i]) { cout << boolarray[i]; } } } i thought boolean array initializing false values... then, if run code in eclipse (on ubuntu), works fine me, function prints values because !boolarray[i] return true (but values not false values, garbage values). if run in visual studio, values garbage values too, function not print value (because !boolarray[i] returns false). why array values not false values default?!? , why !boolarray[i] returns false in visual studio returns true in eclipse?!? i read question: set default value of dynamic array

our current connection configuration looks this: mongoclientoptions.builder() .autoconnectretry(true).maxautoconnectretrytime(1200000) .sockettimeout(30000).connecttimeout(15000).build(); // sockettimeout: 30s, connectiontimeout 15s, reconnectretry: 20min autoconnectretry , maxautoconnectretrytime deprecated in current version ( source code ) , removed: "there no replacement method. use connecttimeout property control connection timeout." i thought retries , connection timeouts 2 different things. know why changed , (internal) implications has? there lot of confusion meaning of autoconnectretry. people think means that, if operation failed due ioexception, driver retry operation until maxautoconnectretrytime elapsed. not case. all means that, on calls socket.connect(), driver retries failed attempt connect until maxautoconnectretrytime elapsed. connecttimeout for. additional capability of autoconnectretry can specify longer connect timeou

i dealing loading data 250 mb csv file matlab. data looks following: col1 col2 col3 col4 col5 1 5/1/2014 1 18.4765 18.1938 when like: y = csvread('datafile.csv'); the second column date , hence when use csvread, variable y appears following: 1 2014 -5 -1 1 18.4765000000000 18.1938000000000 0 0 0 0 0 0 0 so, problems dealing are: (1) dates messed (2) row zeros gets added how read such data file ? from csvread documentation: read comma-separated value file your csv file contains contents besides values. if have microsoft excel can try using xlsread: http://www.mathworks.com/help/matlab/ref/xlsread.html [num,txt,raw] = xlsread('myfile.xls'); otherwise have done manually, can try function answer: import csv file mixed data types
