File input on change in vue.js : <p>Using plain HTML/JS, it is possible to view the JavaScript File objects of selected files for an input element like so:</p>
<pre><code><input type="file" id="input" multiple onchange="handleFiles(this.files)">
</code></pre>
<p>However, when converting it to the 'Vue' way it doesn't seem to work as intend and simply returns <code>undefined</code> instead of returning an Array of File objects. </p>
<p>This is how it looks in my Vue template:</p>
<pre><code><input type="file" id="file" class="custom-file-input"
v-on:change="previewFiles(this.files)" multiple>
</code></pre>
<p>Where the <code>previewFiles</code> function is simply the following (located in methods): </p>
<pre><code> methods: {
previewFiles: function(files) {
console.log(files)
}
}
</code></pre>
<p>Is there an alternate/correct way of doing this? Thanks</p>

Handle multiple events in gpio : <p>I'm new to embedded programming and I apologise in advance for any confusion.</p>
<p>I need to handle multiple events from different devices connected to a gpio. These events need to be monitored continually. This means that after one event is generated and handled, the code needs to keep monitoring the device for other events.</p>
<p>I understand the concept of interruptions and polling in Linux (the kernel gets an interruption and dispatch it to the handler which goes on up to the callee of an epoll which is inside an infinite loop while(1)-like). </p>
<p>This is fine for one-time, single-event toy models. In a embedded system with limited resources such as the <a href="https://www.digikey.com/eewiki/display/linuxonarm/AT91SAM9x5#AT91SAM9x5-LinuxKernel" rel="nofollow noreferrer">AT91SAM9x5</a> that runs at 400mhz and has 128mb of ram what can I do ? I believe that the while(1)-like pattern isn't the best choice. I've heard good things about thread pool solution but at the heart of each thread don't we find a while(1) ? </p>
<p>What are my options to attack this problem ?</p>
<p>Thank you in advance !</p>

how to split ruby code like c or c++ code : I'd like to split the long ruby code into another ruby source files, in c source file , I can put the code like this:
```
a.c
if (xxx)
#include "my_file.c"
my_file.c
printf("yes we are in xxx conditions");
```
now in ruby code I can't do that like:
```
a.rb
case condition
when "a"
puts "a"
load (or include "b.rb")
end
b.rb
when "b"
puts "we are in b.rb"
```
so how to solve the ruby code just like in c source file. thanks

Is it ok to use ReactDOMServer.renderToString in the browser in areas where React isn't directly managing the DOM? : <p>I'm working on an app using <a href="http://leafletjs.com/" rel="noreferrer">Leaflet</a> (via <a href="https://github.com/PaulLeCam/react-leaflet" rel="noreferrer">react-leaflet</a>). Leaflet directly manipulates the DOM. The react-leaflet library doesn't change that, it just gives you React components that you can use to control your Leaflet map in a React-friendly way.</p>
<p>In this app, I want to use custom map markers that are divs containing a few simple elements. The way to do that in Leaflet is to set your marker's <code>icon</code> property to a <a href="http://leafletjs.com/reference.html#divicon" rel="noreferrer">DivIcon</a>, in which you can set your custom HTML. You set that inner HTML by setting the DivIcon's <code>html</code> property to a string containing the HTML. In my case, I want that HTML to be rendered from a React component.</p>
<p>In order to do that, it seems like the correct approach is to use <code>ReactDOMServer.renderToString()</code> to render the Component that I want inside the map marker into a string, which I would then set as the <code>html</code> property of the DivIcon:</p>
<p><strong><em>MyMarker.js:</em></strong></p>
<pre><code>import React, { Component } from 'react'
import { renderToString } from 'react-dom/server'
import { Marker } from 'react-leaflet'
import { divIcon } from 'leaflet'
import MarkerContents from './MarkerContents'
export class MyMarker extends Component {
render() {
const markerContents = renderToString(<MarkerContents data={this.props.data} />)
const myDivIcon = divIcon({
className: 'my-marker',
html: markerContents
})
return (
<Marker
position={this.props.position}
icon={myDivIcon} />
)
}
}
</code></pre>
<p>However, according to the <a href="https://facebook.github.io/react/docs/top-level-api.html#reactdomserver.rendertostring" rel="noreferrer">React docs</a>:</p>
<blockquote>
<p>This [renderToString] should only be used on the server.</p>
</blockquote>
<p>Is this a strict rule, or is it only meant to dissuade people from circumventing ReactDOM's efficient management of the DOM?</p>
<p>I can't think of another (better) way to accomplish what I'm after. Any comments or ideas would be greatly appreciated.</p>

Efficient and simple comparison operators for structs : <p>The application I am working on currently has a large number structs which contain data which is input from various sources such as data bases and files. For example like this:</p>
<pre><code>struct A
{
float val1;
std::string val2;
int val3;
bool operator < (const A& other) const;
};
</code></pre>
<p>For processing, these structs are stored up in STL-containers, such as maps and therefore need a comparison operator. These are all the same and using simple boolean logic they can be written like this:</p>
<pre><code>bool A:operator < (const A& o) const {
return val1 < o.val1 ||
(val1 == o.val1 && ( val2 < o.val2 ||
(val2 == o.val2 && ( val3 < o.val3 ) ) );
}
</code></pre>
<p>This seems efficient, but has several drawbacks:</p>
<ol>
<li>These expressions get huge if the structs as a dozen or more members.</li>
<li>It is cumbersome to write and maintain if members change.</li>
<li>It needs to be done for every struct separately.</li>
</ol>
<p>Is there a more maintainable way to compare structs like this?</p>

Check each collumn and row for duplicate C++ : I have to check if latin square is true by user input. But i can't figure out how to do the check part. Where it checks each collumn and row for duplicate numbers.
This is what i came up with, but it doesn't seem to work properly
// arr= input by user in array, and n= array length by user input
bool latin(int**arr,int n)
{
int times=0;
int s;
for(int j=0;j<n;j++)
{
for(int i=0; i<n;i++){
if (arr[i][j]==s) times++;
}
}
if (times != 1) return false;
else return true;
}

Reverse element in array without array reverse method : <p>I am new here and new to programming.
I have an assignment which consists of reversing the elements of an array, but the array reverse method cannot be used. I do not know how I can achieve this. I tried using a for loop but it did not work.
Thanks in advance.</p>

How many is too many for create dispatch_queues in GCD (grand central dispatch)? : <p>There is a wonderful article about a lightweight notification system built in Swift, by Mike Ash: (<a href="https://www.mikeash.com/pyblog/friday-qa-2015-01-23-lets-build-swift-notifications.html" rel="noreferrer">https://www.mikeash.com/pyblog/friday-qa-2015-01-23-lets-build-swift-notifications.html</a>).</p>
<p>The basic idea is you create objects that you can "listen" to i.e. invoke a callback on when there is some state change. To make it thread-safe, each object created holds its own dispatch_queue. The dispatch_queue is simply used to gate critical sections:</p>
<pre><code>dispatch_sync(self.myQueue) {
// modify critical state in self
}
</code></pre>
<p>and moreover it likely won't be in high contention. I was kind of struck by the fact that <em>every</em> single object you create that can be listened to makes its own dispatch queue, just for the purposes of locking a few lines of code.</p>
<p>One poster suggested an OS_SPINLOCK would be faster and cheaper; maybe, but it would certainly use a lot less space.</p>
<p>If my program creates hundreds or thousands (or even tens of thousands of objects) should I worry about creating so many dispatch queues? Probably most won't ever even be listened to, but some might.</p>
<p>It certainly makes sense that two objects not block each other, i.e. have separate locks, and normally I wouldn't think twice about embedding, say, a pthread_mutex in each object, but an entire dispatch queue? is that really ok?</p>

How to convert string to objectId in LocalField for $lookup Mongodb : <p>I want to add join collections using <code>$lookup</code> in mongodb. I am trying as below</p>
<pre><code>{

localField:"assignedId",
foreignField:"_id",

</code></pre>
<p>Now I have two collections </p>
<p><strong>User</strong> contains <code>objectid</code> of users like <code>"_id" : ObjectId("56ab6663d69d2d1100c074db"),</code></p>
<p>and <strong>Tasks</strong> where it contains <code>assignedId</code> as a <code>string</code> <code>"assignedId":"56ab6663d69d2d1100c074db"</code></p>
<p>Now, when applying $lookup in both collection its not working because Id's are not matching.</p>
<p>For that I googled it and found a solution that to include</p>
<p><code>{ $project: { assignedId: {$toObjectId: "$assignedId"} }}</code> </p>
<p>but this solution is not working for me, Its throwing an error:</p>
<pre><code>assert: command failed: { "ok" : 0, "errmsg" : "invalid operator '$toObjectId'", "code" : 15999 } : aggregate failed

What is the most efficient way to pass a non generic function? : <p>I am learning functional programming in C++. My intention is to pass a non generic function as argument. I know about the template method, however I would like to restrict the function signature as part of the API design. I worked out 4 different methods <a href="http://cpp.sh/2wds" rel="noreferrer">example on cpp.sh</a>:</p>
<pre><code>// Example program
#include <iostream>
#include <string>
#include <functional>
typedef int(functor_type)(int);
int by_forwarding(functor_type &&x) {
return x(1);
}
int functor_by_value(functor_type x) {
return x(1);
}
int std_func_by_value(std::function<functor_type> x) {
return x(1);
}
int std_func_by_forwarding(std::function<functor_type> &&x) {
return x(1);
}
int main()
{
std::cout << functor_by_value([](int a){return a;}); // works
std::cout << std_func_by_value([](int a){return a;}); // works
std::cout << std_func_by_forwarding(std::move([](int a){return a;})); // works
//std::cout << by_forwarding([](int a){return a;}); // how to move lambda with forwarding ?
}

I cant seem to find a way to cut the string using only string methods. Also another problem arose when I have to also be able to adjust if their isn't a middle name either. if anyone can help me or lead me in the right direction that would be nice.

Coming From EF TO EF Core How Do I use using statement correct : I must be doing something wrong in my Context I have my context below which I want to wrap up in my manager class. And I want to be able to use the using statement so that my context is used only once.
public class xxxDbContext : DbContext
{
public xxxDbContext(DbContextOptions<xxxDbContext> options)
: base(options)
{ }
public DbSet<JobsList> JobListingss { get; set; }
public DbSet<Clients> ClientListings { get; set; }
public DbSet<Engineer> EngineerListing { get; set; }
public DbSet<Case> CasesListing { get; set; }
}
But When I want to use my context in my using statement such as
public class xxxContext
{
xxxDbContext _db = new xxxDbContext();
public List<Case> GetAllCases(int databaseId)
{
List<Case> q = new List<Case>();
using (var myContext = new xxxDbContext(what must I reference here ?)))
{
q = myContext.Cases.Where(w => w.databaseID == databaseId).OrderBy(o => o.CustomerName).ToList();
}
return q;
}
}
Before I was just able to make a parameter less construct can I do same here for core or does that override what is meant to be done.
Also what is best practise should I have a separate class for all these functions or should I have a partial class based on my context?.

difference between s.size() and strlen : i recently did this question
**Specification:**
> Input Format The first line contains the number of testcases, T. Next,
> T lines follow each containing a long string S.
>
> Output Format For each long string S, display the no. of times SUVO
> and SUVOJIT appears in it.
I wrote the following code for this :
#include <bits/stdc++.h>
using namespace std;
int main()
{
int t;
cin>>t;
while(t--){
int suvo=0;
int suvojit=0;
string s;
cin>>s;
for(int i=0;i<=s.size()-7;i++){
if(s.substr(i,7)=="SUVOJIT")suvojit++;
}
for(int i=0;i<=s.size()-4;i++){
if(s.substr(i,4)=="SUVO")suvo++;
}
cout<<"SUVO = "<<suvo-suvojit<<", SUVOJIT = "<<suvojit<<"\n";
}
return 0;
}
The code about gave out of bounds exception for substr() function for this test case:
> 15
RSUVOYDSUVOJITNSUVOUSUVOJITESUVOSUVOSGSUVOKSUVOJIT

> AG NSUVOJITSUVOSUVOJIT CGJGDSUVOEASUVOJITSGSUVO
However , when instead of using the s.size() function , i converted the string into a char constant and took out the length of it using strlen , then the code caused no error and everything went smoothly ..
**So, my question is ...Why did this happen?**
This is my working code with the change :
#include <bits/stdc++.h>
using namespace std;
int main()
{
int t;
cin>>t;
while(t--){
int suvo=0;
int suvojit=0;
string s;
cin>>s;
int le=strlen(&s[0]);
for(int i=0;i<=le-7;i++){
if(s.substr(i,7)=="SUVOJIT")suvojit++;
}
for(int i=0;i<=le-4;i++){
if(s.substr(i,4)=="SUVO")suvo++;
}
cout<<"SUVO = "<<suvo-suvojit<<", SUVOJIT = "<<suvojit<<"\n";
}
return 0;

C++ switch statement calculator : <p>I need to make a calculator for C++ using switch statement. Exact instructions are:
Part #1:</p>

<pre><code> Menu
=============
+) Add
-) Subtract
*) Multiply
/) Divide
x) Exit
==============
Enter your choice:
</code></pre>
<p>For a user selection of +, -, *, or /, the program prompts for two operands and then performs the calculation and displays the result
If the user selects X or x, the program ends.
If the user selects a character other than +, -, *, /, x, or X, the program displays an error message that the selection is invalid.
Part #2:</p>
<p>Add the following input validation to your solution to Calculator Part #1:</p>
<p>If the user selects the divide choice, /, and second operand is zero, the program responds that “Division by zero is not possible.”</p>
<p>I would love to go through all of my previous attempts but unfortunately I left my drive at home and now I'm down to the wire. I CAN however tell you I was using this type of format:</p>
<pre><code>int main()
{
char choice;
cout << "Enter A, B, or C: ";
cin >> choice;
switch (choice)
{
case 'A': cout << "You entered A.\n";
break;
case 'B': cout << "You entered B.\n";
break;
case 'C': cout << "You entered C.\n";
break;
default: cout << "You did not enter A, B, or C!\n";

How to return int and string attributes in a single java method : I would like to return the values of all the attributes from the Baseballplayer class. The method that needs to do this must be the public string getBaseballPlayer(int i) method (because I need to reference this method inside getBaseballPlayers() to return all the values as an arraylist of strings) I'm having trouble doing this because all the attributes have different datatypes (int, string, Height).
Ive tried doing this
public String getBaseballPlayer(int i){
ArrayList <String> bArray = new ArrayList <String>();
bArray.add(getHometown());
bArray.add(getState());
bArray.add(getHighSchool());
bArray.add(getPosition());
however it only works for the string methods, and doesn't necessarily return the actual values but rather the get methods for each string attribute.
public class BaseballPlayer extends Player implements Table {
private int num;
private String pos;
public BaseballPlayer( int a, String b, String c, int d,
String e, String f, String g, Height h){
super(a,ft,in,c,d,e,f,ht);
num = a;
pos = b;
}
public BaseballPlayer(){}
//Returns the value of a specific attribute. The input parameter start
with 0 for the first attribute, then 1 for the second attribute and so
on.
//you can use getBaseballPlayer(int i) in getBaseballPlayers( ) with a for
loop getting each getBaseballPlayer(int i).
public String getBaseballPlayer(int i){
ArrayList <String> bArray = new ArrayList <String>();
bArray.add(getHometown());
bArray.add(getState());
bArray.add(getHighSchool());
bArray.add(getPosition());
return (bArray);
}
//Returns the value of all attributes as an ArrayList of Strings.
public ArrayList <String> getBaseballPlayers(){
}
I'm just looking for the simplest way to return each attributes value, then using that method return each value as an arraylist of strings in another method.

Calling another method inside antoher method? digital image processing : I am new into Java and I am trying to understand a piece of code:
public class Image {
...
public float getPixel(int height, int width) {
return data[height][width];
}
public void setPixel(float value, int height, int width) {
if (value > getMax())
value = getMax();
if (value < 0)
value = 0;
data[height][width] = value;
}
private Image(String magicNumber, int height, int width, float max) {
this.magicNumber = magicNumber;
this.width = width;
this.height = height;
this.max = max;
data = new float[height][width];
}
...
public Image clone() {
Image clone = new Image(getMagicNumber(), getHeight(), getWidth(), getMax());
for (int i = 0; i < getHeight(); i++) {
for (int j = 0; j < getWidth(); j++) {
clone.setPixel(getPixel(i, j), i, j); /** trying to understand this line */
}
}
return clone;
}
What does `clone.setPixel(getPixel(i, j), i, j);` exactly do? And what I mostly don't understand is what `clone.` which is before `setPixel(getPixel(i, j), i, j);` is doing?

Default constructor for IntentService (kotlin) : <p>I am new with Kotlin and little bit stack with intentService. Manifest shows me an error that my service doesn't contain default constructor, but inside service it looks ok and there are no errors.</p>

constructor(name:String?) : super(name) {

override fun onCreate() {
super.onCreate()

Log Non-fatal errors on Crashlytics : <p>On iOS it's possible to use <a href="https://docs.fabric.io/apple/crashlytics/logged-errors.html" rel="noreferrer">recordError(error)</a> to log non-fatal errors on Crashlytics but apparently this feature is not available for Android.</p>
<p>The only alternative I found is to use <a href="https://docs.fabric.io/android/crashlytics/caught-exceptions.html" rel="noreferrer">logException(e)</a>.
I manage errors on my app and I want to log when specifics errors codes are returned. So, on Crashlytics I'd like the non-fatal errors to be referenced by the errorCode. But using the <em>logException(e)</em> method, errors are referenced by the method where <em>logException(e)</em> has been called.</p>
<p>How can I do that?</p>

When to provision in Packer vs Terraform? : <p>I am sitting with a situation where I need to provision EC2 instances with some packages on startup. There are a couple of (enterprise/corporate) constraints that exist:</p>
<ul>
<li>I need to provision on top of a specific AMI, which adds enterprisey stuff such as LDAP/AD access and so on</li>
<li>These changes are intended to be used for all internal development machines</li>
</ul>
<p>Because of mainly the second constraint, I was wondering where is the best place to place the provisioning. This is what I've come up with</p>
<p><strong>Provision in Terraform</strong></p>
<p>As it states, I simply provision in terraform for the necessary instances. If I package these resources into modules, then provisioning won't "leak out". The disadvantages</p>
<ul>
<li>I won't be able to add a different set of provisioning steps on top of the module? </li>
<li>A change in the provisioning will probably result in instances being destroyed on apply?</li>
<li>Provisioning takes a long time because of the packages it tries to install</li>
</ul>
<p><strong>Provisioning in Packer</strong></p>
<p>This is based on the <a href="https://www.packer.io/intro/getting-started/build-image.html" rel="noreferrer">assumption</a> that Packer allows you to provision on top of AMIs so that AMIs can be "extended". Also, this will only be used in AWS so it won't use other builders necessarily. Provisioning in Packer makes the Terraform Code much simpler and terraform applies will become faster because it's just an AMI that you fire up.</p>
<p><strong>For me both of these methods have their place. But what I really want to know is when do you choose Packer Provisioning over Terraform Provisioning?</strong></p>

Add ssl certificate to selenium-webdriver : <p>I use selenium for end-to-end test with chromeDriver. The websites to test require an ssl certificate. When I manually open the browser, there is a popup that lets me select an installed certificate. Different tests access different URLs and also need different certificates. However, if I run the tests in headless mode, there is no popup. So I need a way to programatically set a certificate (eg. set a <code>.pem</code> file) to be used for the current test.</p>
<p>How can I achieve this?
I tried setting up a <a href="https://github.com/lightbody/browsermob-proxy" rel="noreferrer">browserMob</a> proxy which I then configured as a proxy in selenium - however, this does not seem to do anything... Are there better approaches? What am I doing wrong? Here's what I tried:</p>
<pre class="lang-java prettyprint-override"><code>PemFileCertificateSource pemFileCertificateSource = new PemFileCertificateSource(
new File("myCertificate.pem"),
new File("myPrivateKey.pem"),
"myPrivateKeyPassword");
ImpersonatingMitmManager mitmManager = ImpersonatingMitmManager.builder()
.rootCertificateSource(pemFileCertificateSource)

Can we use the ES6 class syntax in AWS Lambda? : <p>I would like to use the ES6 class syntax in AWS Lambda using Node 6.10, but I cannot get it to work:</p>

constructor(event, context, callback) {
callback(null, `all seems well!`);
}
}
// module.exports.handler = widget; // "Process exited before completing request"
module.exports.handler = new widget(); // "callback is not a function"

<p>Has anyone had success with using the class syntax? The class constructor does not get seen as a handler function apparently.</p>

Multiple WordPress sites with one shared DB using Docker : <p>I want to run multiple WordPress websites with one shared database using docker.</p>
<p>Is it possible to specify a database and set an appropriate volume to a certain sql file to initialize WordPress for each container in its <code>docker-compose.yml</code> file?</p>
<hr>
<p>For example, I have three <code>docker-compose.yml</code> files for a shared container, siteA and siteB.</p>
<p>When I run <code>docker-compose up</code> in <code>./shared</code>, two DBs will be created for the two sites (example_a and example_b).</p>
<p>And when I run <code>docker-compose up</code> in <code>./siteA</code>, I want to change current DB to <code>example_a</code>, and initialize the site with a certain amount of data by sql volumed from <code>./siteA/mysql/setup.sql</code>.</p>
<p>Same thing goes with siteB.</p>
<p>I know I can specify a database and volume like <code>-
WORDPRESS_DB_NAME: example_a</code> and <code>- ./db-data/mysql.dump.sql:/docker-entrypoint-initdb.d/install_wordpress.sql</code> in mysql section in <code>docker-compose.yml</code> but I only have one shared mysql and cannot specify DB and volume for each site.</p>

Different routes for different subdomains in Nuxt.js : <p>Suppose there're two subdomains working for one nuxt instance. They should have different pages structure. For example it can be:</p>
<pre><code>pages/
index.vue // technical entry point that has some logic for determining what routes subtree should be used
subdomain1/
index.vue // entry point for subdomain1.mysite.com/
page1.vue // entry point for subdomain1.mysite.com/page1
subdomain2/
index.vue // entry point for subdomain2.mysite.com/
page1.vue // entry point for subdomain2.mysite.com/page1
page2.vue // entry point for subdomain2.mysite.com/page2
</code></pre>
<p>The folder structure can be different. The goal is to be able to load different pages for different subdomains. <code>subdomain1.mysite.com/page1</code> has to load one file (e.g. <code>pages/subdomain1/page1.vue</code>) while <code>subdomain2.mysite.com/page1</code> has to load the other file (e.g. <code>pages/subdomain2/page2.vue</code>).</p>
<p>We can use <code>nuxtServerInit</code> action for determining the subdomain, so there's some <code>this.$store.state.ux.subdomain</code> variable that is eiter subdomain1 or subdomain2. But the rest is not clear for me. </p>
<p>Is it possible to achieve in nuxt.js? If it is, I suppose we should use named views <code><nuxt-child :name="subdomain"/></code> and <code>extendRoutes</code> in nuxt.config.js somehow, but I was not able to achieve it so far. Any help would be appreciated.</p>
