i'm trying generate .json file download using codeigniter's force_download() in ajax call, doesn't work expected. here ajax call: $.ajax({ url: /myfunction, type: 'post', data: {value_sent: my_json_array} }); and php function: public myfunction() { $dl_array = $this->input->post("value_sent"); $this->load->helper('download'); force_download("file.json", $dl_array); } data sent (i double checked), download prompt never shown. assume force_download() fails, don't understand why. any appreciated, thanks! this isn't problem codeigniter, it's limitation of javascript. can't download files via ajax, referenced in download file jquery.ajax . you can't through ajax because javascript cannot save files directly user's computer (out of security concerns)

i have list of objects. list<myobject> mylist; this list populated in beginning , no update done after that. the order of objects in list significant because need iterate on list in order later. during execution of program, need find index of given myobject in mylist ; i know can use mylist.indexof(object) worried performance. going use hashmap map each myobject in mylist index in mylist can find index efficiently. but not sure whether missing trivial , going use 2 containers redundant data done using different container. so, can see better way this? you can use linkedhashmap contain myobject instances. map<string, myobject> map = new linkedhashmap<string, myobject>(); hash table , linked list implementation of map interface, predictable iteration order. this allow have 1 collection both.

as dont have list data type in realm, how can use arraylist<string> in realm object? had same question arraylists of custom models make i.e. arraylist<custommodel> understand first have make realmobject of same custom model using public class customobject extends realmobject { private string name; private string age; } and can use private realmlist<customobject> customobjectlist; in realmobject do have same arraylist of string? 1. making string object 2. use object in realm list yes, have manually box strings in stringobject. we'd add support realmlist<string> , realmlist<integer> , etc., it's long way out.

a constructor 'special' member function task initialize objects of class. it special because name same class name. constructor invoked whenever an object of associated class created.it called constructor because constructs value of data members of class. a constructor declared , defined follows: //class constructor class integer { int m,n; public: integer(void); // constructor declared }; integer::integer(void)// constructor defined { m=0;n=0; } we can not refer addresses why? because language doesn't allow way take address of constructor. or, if you're asking why it's not allowed: because there's no reason so. you'd take address of function in order call it, , never call constructor directly. it's called indirectly, result of creating object.

i using logrus in go app. believe question applicable other logging package (which doesn't offer external file based configuration) well. logrus provides functions setup various configuration, e.g. setoutput, setlevel etc. like other application need logging multiple source files/packages, seems need setup these options in each file logrus. is there way setup these options once somewhere in central place shared on application. way if have make logging level change can in 1 place , applies components of app. you don't need set these options in each file logrus. you can import logrus log : import log "github.com/sirupsen/logrus" then functions log.setoutput() functions , modify global logger , apply file includes import. you can create package global log variable: var log = logrus.new() then functions log.setoutput() methods , modify package global. awkward imo if have multiple packages in program, because each of them has different log

in asp.net mvc, difference between: html.partial , html.renderpartial html.action , html.renderaction html.action invokes controller's action, means instantiates controller entity, calls action method, builds model returns view result. html.partial uses created model (or can called without model @ all) render specified view. when use 1 on other? if have model , want have reusable view, opt html.partial . if see piece deserves own model , action, maybe makes sense use html.action . this question discussed in greater details in this article , , see above excerpt it.

i'm using c , have 2d array representing square matrix. want calculate matrix power of n , given integer. i'm after efficient way this. first thought multiply matrix n times heard of exponentiation squaring. i'm not sure how implement this, please guide me through it? here basic outline: matrix matrixexponent(matrix m, int n) { matrix accumulator = matrixidentity(); matrix power2 = m; while(n != 0) { if(n & 1) accumulator = matrixmultiply(&accumulator, &power2); power2 = matrixmultiply(&power2, &power2); n = n / 2; } return accumulator; } you store accumulator, partially computed exponent. given integer exponent can broken down series of power-of-2 exponents multiplied together. example when raising array power of 14 (1110 in binary), matrix multiplied 14 times equal to: m 14 = m 8 * m 4 * m 2 so compute powers of 2 repeatedly multiplying pow

i got weird problem when trying out webdriverjs on windows machine , or suggestion on one. follow instruction online, first npm install selenium-webdriver, download chromedriver , configure path. before proceed testing double check installation, chrome , firefox working , when running "chromedriver" on cmd works correctly "starting chromedriver 2.14.313457 on port 9515 local connections allowed." assume system setup correct. tried first simple example using js. below code: var webdriver = require('selenium-webdriver'); var driver = new webdriver.builder(). withcapabilities(webdriver.capabilities.firefox()). build(); driver.get('http://www.google.com/ncr'); driver.sleep(10000); driver.quit(); this works fine firefox,and firefox opened , directed google page. however, when switch second example using chrome, chrome never opened , no error messages showed, stuck there. here second example used, difference first 1 changing firefox chrom

i want shuffle array, find method random.shuffle(x) , best way randomize list of strings in python can like import random rectangle = [(0,0),(0,1),(1,1),(1,0)] # want # disorderd_rectangle = rectangle.shuffle now can away with disorderd_rectangle = rectangle random.shuffle(disorderd_rectangle) print(disorderd_rectangle) print(rectangle) but returns [(1, 1), (1, 0), (0, 1), (0, 0)] [(1, 1), (1, 0), (0, 1), (0, 0)] so original array changed. how can create shuffled array without changing original one? people here advising deepcopy, surely overkill. don't mind objects in list being same, want shuffle order. that, list provides shallow copying directly. rectangle2 = rectangle.copy() random.shuffle(rectangle2) about misconception: please read http://nedbatchelder.com/text/names.html#no_copies

i'm using pjax in such way: <?php pjax::begin([ 'id' => 'clients-list', 'enablepushstate' => false, 'enablereplacestate' => false, ]); ?> and works fine url in browser, replaces links pagination in gridview (link action in controller processing ajax requests). how avoid it? by default, links inside pjax container trigger pjax request. to avoid it, add 'data-pjax' => 0 attribute them, , in case ignored.

the situation have in mind using python extension module can call python, there may mixture of python , non-python stack frames @ point when greenlet yields. i assume if module uses thread-local storage misbehave greenlets. is there other reason why thread-safe module might not greenlet-safe? edit: want know whether there difference between way context switches implemented greenlets vs. regular threads. greenlets take shortcuts might work python break kinds of extension module? greenlets stay within single thread in python. cannot jump thread. if code thread-safe, greenlet safe. another way @ greenlets execute 1 @ time, have little issues have threads.

i have protobuf protocol file looks this: message foo { message bar { required string name = 1; required string value = 2; } message baz { required bar = 1; } } given protocol file, need write encoder using protobuf-c, c extension protobuf. wrote following code: foo myfoo = foo__init; foo__bar mybar = foo__bar__init; foo__baz mybaz = foo__baz__init; mybaz.a = &mybar; however, stuck @ point on how serialize mybaz . generated struct foo, not contain entry can assign mybaz to. , no method generated directly pack baz. in python, lot more simpler, since mybaz.serializetostring() function had been generated. how should go in c? declaring nested types in protocol buffers declaring nested classes in c++ or static inner classes in java. declares new type; not add field outer type. so, in proto schema, foo empty message -- has no fields. true regardless of programming language you're working in. probably meant this:

i learning work mysql , c++ in ubuntu os. there several tutorials on how interface mysql c++ in visual studio or in windows, not 1 linux. mysql website not describe on this. can suggest me link tutorial, book or thing gives information how interface c++ mysql in linux. database in linux machine itself. great help. mysql is database, , gain access data within c++ need able “talk” database via queries (just on mysql command line interface e.g. select * tablename), connection process similar command line interface need supply connection details in hostname (localhost normally), username, password, database use , there other details can pass e.g port number more information can gained the mysql api pages. this link has example connect mysql in c++ unix

i have nhibernate mapping on tables in our oracle 11g database, 1 of tables contains clob column. when attempting query out ~10,000 rows of data, query takes forever. when querying subset of 200 rows, query ran 3 minutes. mathematically means it'll take 2.5 hours query 10,000 rows. if remove clob column nhibernate mapping, same query takes ~3 seconds 200 rows, , ~2 minutes 10,000 rows. is 1 of 'by design' issues, either oracle driver, or way nhibernate handles clobs?
