How to subtract military time in JavaScript/JQuery? : I have two time values that should subtract and output the difference in hours. For example I get the values in this format:
0530-2400
That value is string, I guess that converting to JavaScript date object is the first step. Here is what I have so far:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
var time = "0530-2400",
arr = [];
arr = time.split('-');
var dateObj = new Date(),
hours1 = dateObj.setHours(Number(arr[0].substring(0, 2))),
hours2 = dateObj.setHourse(Number(arr[1].substring(0, 2))),
minutes1 = dateObj.setMinutes(Number(arr[0].substring(2, 4))),
minutes2 = dateObj.setMinutes(Number(arr[1].substring(2, 4)));
console.log(hours1);
console.log(minutes1);
console.log(hours2);
console.log(minutes2);
<!-- end snippet -->
The output for the time I showed above should be `18.5` hours. If we subtract `24-5.5(530) = 18.5`
The increments are always on `15,30 or 45` minutes. Is there a good way to convert string and then do the math in JS?

Ordering multi-dimensional Array in Python : Lets say I have a multidimensional array [A][B][C], and I want to order the array with respect to a, ofcourse the relationship of the values of B and C which corresponded to their neighbouring A needs to be maintained...
Also assuming we have multiple A's with the same value, how do we order the B's so that we have A ordered primarily then B ordered if its possible.
Something like
`
(1,2,3)
(1,3,7)
(1,4,5)
(1,5,2)
(2,3,5)
(2,4,9)
(2,5,0)
...`

How to initialize an Int from a map Value, C++ : <p>I have a large global map in a header of weapon names and ID numbers from a video game . I am trying to find a way that I can take user input for the name and return the item number. For this I created a new int and would like to initialize it with the map value after searching for the name. What is the best way to do this?</p>
<pre><code>//header
#include <map>
#include <string>
using namespace std;
typedef std:: map <std :: string, int> weaponMap;
inline
weaponMap & globalMap() {
static weaponMap theMap;
static bool firstTime = true;
if (firstTime) {
firstTime = false;
theMap["weaponOne"] = 854000;
}
}
//Source.cpp
#includes "globalMap"
int swapWeapon = weaponMap::["weaponOne"];
cout << swapWeapon;
</code></pre>

Save Time (NSDate) in NSUserDefaults [Swift 2] : please excuse my bad english skills. I am trying to save the time once the "user" reachs the Limit. So the limit is 10 for example and once he reachs this limit, i want to save the current time. Then he has to wait 1 hour to continue playing. I started doing this, but I already get an error, when I try this:
var CurrentTime = NSDate()
CurrentTime = NSUserDefaults.standardUserDefaults()
Error: Cannot assign value of type 'NSUserDefaults' to type 'NSDate'
It seems like swift cannot save a 'NSDate' as a 'NSUserDefault'. I would be happy if you could help me out :)

Argument of type 'HTMLElement' is not assignable to parameter of type 'CanvasImageSource' : <p>I am trying to get the same image to load into all of the canvas in my HTML. I had previously written my whole webpage in javascript but now I am learning angular and typescript.</p>
<p>I am getting this error highlighted in Visual Studio Code:</p>
<blockquote>
<p>Argument of type 'HTMLElement' is not assignable to parameter of type 'CanvasImageSource'.
Type 'HTMLElement' is missing the following properties from type 'HTMLVideoElement': height, msHorizontalMirror, msIsLayoutOptimalForPlayback, msIsStereo3D, and 80 more.ts(2345)</p>
</blockquote>
<p>But I get no error shown in the console. I can get the image to load on the HTML within the canvas (so it is working).</p>
<p>This is my ts:</p>
<pre><code>import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-map',
templateUrl: './map.component.html',
styleUrls: ['./map.component.scss']
})
export class MapComponent implements OnInit {
constructor() { }
ngOnInit() {
document.querySelectorAll("canvas").forEach(c=>{
var ctx = c.getContext("2d");
var img = document.getElementById("P43");
ctx.drawImage(img,0,0,106,50); //(image, offsetx, offsety, x, y)
});
}
}
</code></pre>
<p>VS Code highlights the error on this line <code>ctx.drawImage(img,0,0,106,50); //(image, offsetx, offsety, x, y)</code>, it highlights <strong>img</strong> and displays the error.</p>
<p>I have tried to search this but the only solutions I have found are for when you had the ID for tag ( I don't as it is all canvas' on the page.) or if there is an input.</p>
<p>Any help is appreciated.</p>

Select 3 items or 4 items out of 8 items : I am trying to get 3 or 4 items out of an array of 8 numbers (1-8). If i try to print the array of the 3 or 4 items. Most of the trys it worked but some times I only get some numbers and a 0 which isn't in the array. Like this [2, 5, 3, 0].
private int[] randomPeople() {
int[] result = {0, 0, 0, 0};
int[] arr = {1, 2, 3, 4, 5, 6, 7, 8};
return getRandomPeople(result, arr);
}
private int[] getRandomPeople(int[] result, int[] arr) {
int number;
for (int i = 0; i < result.length; i++) {
number = (int) (Math.random() * arr.length + 1);
for (int j = 0; j < result.length; j++) {
if (number == result[j]) { //check if the random number is already in the list --> new random int
j = 0;
number = (int) (Math.random() * arr.length + 1);
}
}
for (int j = 0; j < arr.length; j++) { // adds the number to the new array and delete it in the old
if (number == arr[j]) {
result[i] = number;
arr = searchDelete(arr, number);
}
}
}
System.out.println(Arrays.toString(result));
return result;
}
This method is for deleting the searched ID. You have to hand over an array and the int which should be deleted.
private int[] searchDelete(int[] arr, int SRID) {
int pos;
for (pos = 0; pos < arr.length - 1; pos++) {
if (arr[pos] == SRID)
break;
}
while (pos < arr.length - 1) {
arr[pos] = arr[pos + 1];
pos++;
}
int[] arr2 = new int[arr.length - 1];
System.arraycopy(arr, 0, arr2, 0, arr.length - 1);
return arr2;

Como realizar um insert em uma tabela utilizando um parâmetro fixo e um parâmetro "dinâmico" (resultado de um SELECT)) : Preciso fazer um INSERT populando dois campos de uma tabela, onde um parâmetro sempre irá ter o mesmo valor, e o outro parâmetro será resultado de um SELECT.
Segue abaixo a QUERY que elaborei:
INSERT INTO tabelaAlvo (cdCodigo, cdItem)
VALUES (8, (SELECT cdItem FROM outraTabela WHERE cdXxx IN (27) AND cdYyy IN (
3,
16,
63,
121,
256,
257,
258,
259,
260,
261,
262,
263,
264)))
O primeiro atributo sempre deverá ser preenchido com o valor = 8, enquanto o segundo atributo deverá ser preenchido com o resultado do SELECT.
Poderiam me ajudar, por gentileza?

"Define is not defined" in Jest when testing es6 module with RequireJS dependency : <p>I have a Jest test suite that fails to run because the component it's trying to test depends on a RequireJS module. Here's the error I'm seeing:</p>

● Test suite failed to run
ReferenceError: define is not defined
at Object.<anonymous> (node_modules/private-npm-module/utils.js:1:90)

<p>The component has the following import:</p>
<pre><code>import utils from 'private-npm-module';

<p>And the <code>private-npm-module</code> is set up like so:</p>
<pre><code>define('utils', [], function() {
return {};
});
</code></pre>
<p>When <code>MyComponent</code> is transpiled with babel and run in the browser, the dependency operates correctly. This issue only affects the unit test. How can I get my test suite to run on a component with a RequireJS dependency?</p>
<p>I'm using <code>babel-jest</code> as my <code>scriptPreprocessor</code> in package.json's jest config. I'm using jest v0.15.1.</p>

I receive NULL values when trying to send Ajax Jquerry parameters in POST request - MVC CORE : so i'm a little new to MVC core.
My requirement is the following:
I have a "Contact.cshtml" view which contains a contact form.
After the user fills the contact form and clicks the "submit" button, I want to send the entered form parameters to the controller with the Ajax Jquerry Post method, and then send feedback back to the user without refreshing the page.
My Controller Method:
[HttpPost]
public IActionResult Contact(string name, string email, string subject, string message)
{
// Future code will be entered here and do some logic with the parameters
// This will be replaced with a call to a partial View which contains a success message
return View();
}
Part of my Contact.cshtml file:
<form method="post" role="form" id="contactForm">
<div class="form-group">
<label for="name">השם שלך</label>
<input type="text" class="form-control" id="name">
</div>
<div class="form-group">
<label for="email">כתובת מייל</label>
<input type="email" class="form-control" id="email">

<div class="form-group">
<label for="subject">נושא</label>
<input type="text" class="form-control" id="subject">
</div>
<div class="form-group">
<label for="message">הודעה</label>
<textarea class="form-control" id="message" rows="3"></textarea>
</div>
<button type="submit" class="btn btn-theme">שלח</button>
</form>
@section scripts
{
<script>
$('#contactForm').submit(function () {
$.post('',
{
"name": $('#message').toString(),
"email": $('#email').toString(),
"subject": $('#subject').toString(),
"message": $('#message').toString()
}).done(function (response) {
alert("success");
})
});
</script>
}
**I spent Hours on this issue, but I always, and i mean always, receive NULL values for ALL of the form fields in the controller handling method, so please help me, thanks**

C/C++ calculate length of double pointer array : I have a double pointer Array of a structure:
typedef struct Position{
int x;
int y;
} Position;
Position** array = (Position**)malloc(sizeof(Position)*10); //10 elements
array[0] = (Position*)malloc(sizeof(Position));
array[0]->x = 10;
array[0]->y = 5;
Can I calculate the length of set array and if so, how?
The normal way for arrays does not work :
int length = sizeof(<array>)/sizeof(<array>[0]);

Stroustrup - Programming - Principles and Practice C++ (2nd) - TRY THIS - Sec 4.4.2.3 - For loops : The question asks: Rewrite the character value example from the previous Try this to use a for-statement.
With that being said, what I wrote for the previous question was the following which runs fine as well:
#include "pch.h"
#include "iostream"
#include "string"
#include "vector"
#include "algorithm"
#include "cmath"
using namespace std;
int main()
{
char letter = 'a';
int i = 97;
while (i < 123) {
cout << letter << '\t' << i << '\n';
i = i + 1;
letter = letter + 1;
}
Here is what I attempted for the current question:
int main()
{
for ((int i = 97; i < 123; i = i+1; char letter = 'a'; i = i + 1,
letter = letter + 1)
cout << letter << '\t' << i << '\n';
}
In essence what I had gathered from the example was that the difference between the two types of statements was including the control variables and statements within the parentheses of the FOR loop. What is it that I am doing wrong?

Dynamic Programming - Minimum number of coins in C : <p>I have looked through various questions on the site and I haven't managed to find anything which implements this by the following reasoning (so I hope this isn't a duplicate).</p>
<p>The problem I'm trying to solve via a C program is the following:</p>
<blockquote>
<p>As the programmer of a vending machine controller your are required to compute the minimum number of coins that make up the required change to give back to customers. An efficient solution to this problem takes a dynamic programming approach, starting off computing the number of coins required for a 1 cent change, then for 2 cents, then for 3 cents, until reaching the required change and each time making use of the prior computed number of coins. Write a program containing the function <code>ComputeChange()</code>, that takes a list of valid coins and the required change. This program should repeatedly ask for the required change from the console and call <code>ComputeChange()</code> accordingly. It should also make use of “caching”, where any previously computed intermediate values are retained for subsequent look-up.</p>
</blockquote>
<p>After looking around online to find how others have solved it, I found the following example applied with pennies, nickels and dimes:</p>
<p><a href="https://i.stack.imgur.com/dYlPp.png" rel="noreferrer"><img src="https://i.stack.imgur.com/dYlPp.png" alt="enter image description here"></a></p>

Where should pre-processing and post-processing steps be executed when a TF model is served using TensorFlow serving? : <p>Typically to use a TF graph, it is necessary to convert raw data to numerical values. I refer to this process as a pre-processing step. For example, if the raw data is a sentence, one way is to do this is to tokenize the sentence and map each word to a unique number. This preprocessing creates a sequence of number for each sentence, which will be the input of the model. </p>
<p>We need also to post-process the output of a model to interpret it. For example, converting a sequence of numbers generated by the model to words and then building a sentence.</p>
<p><a href="https://www.tensorflow.org/serving/" rel="noreferrer">TF Serving</a> is a new technology that is recently introduced by Google to serve a TF model. My question is that:</p>
<p>Where should pre-processing and post-processing be executed when a TF model is served using TensorFlow serving?</p>
<p>Should I encapsulate pre-processing and post-processing steps in my TF Graph (e.g. using <a href="https://www.tensorflow.org/api_docs/python/tf/py_func" rel="noreferrer">py_fun</a> or <a href="https://www.tensorflow.org/api_docs/python/tf/map_fn" rel="noreferrer">map_fn</a>) or there is another TensorFlow technology that I am not aware of. </p>

tinymce.EditorManager.editors = [];
tinymce.EditorManager.init({ ... some code ...});

Даже, если я пытаюсь удалить редактор после инициализации, эти методы вообще не работают.

Smart pointers as unorderd_map key and compare them by reference : I need `unorderd_map` which will compare elements by reference. I tried to do this by inserting smart pointers as a key (since I do not want to use row pointers) and I implemented `Equal` to compare underlying references of smart pointers. However, the map is not able to find elements correctly.
#include <memory>
#include <unordered_map>
#include <iostream>
using namespace std;
class Node {};
typedef shared_ptr<Node> NodePtr;
struct HashFunction {
unsigned long operator()(const NodePtr& key) const{
return (unsigned long)key.get();
}
};
struct EqualFunction {
bool operator()(const NodePtr& t1, const NodePtr& t2) const {
return t1.get() == t2.get();
}
};
class Map
{
unordered_map<NodePtr, int, HashFunction, EqualFunction> map;
public:
void insert(NodePtr nodeToInsert, int val) {
map.insert({nodeToInsert, val });
}
bool exist(NodePtr node) {
if (map.find(node) == map.end()) return false;
return true;
}
};
int main()
{
Node node; Map map;
auto nodePtr = make_shared<Node>(node);
map.insert(nodePtr, 1);
auto ptrToSameNode = make_shared<Node>(node);
if (map.exist(ptrToSameNode))
cout << "Node exists.";
else cout << "Node doesn't exist.";
}
Above code print "Node doesn't exist" even through I am searching for the same node.

How to use PHP If statement comparing to SQL Date and Current Date? : <p>In my SQL Database i have a date column.
I want to use a PHP if statement to show some text if the date from the DB equals todays date.
Aswell as that, use an else to show something else if the date does not equal today.</p>
<p>Running PHP 7</p>
<p>I have lost count of what i have tried with this but don't seem to get anywhere.</p>
<p>I am fetching the data here:</p>
<pre><code> $sql1 = 'SELECT `date` FROM `operations`.`opsroom` ORDER BY `opsroom`.`date` ASC, `opsroom`.`starttime` ASC LIMIT 1';
$nextsession = mysqli_query($conn, $sql1);
</code></pre>
<p>Later on in the file is where i am using this:</p>
<pre><code> <?php
while ($row = mysqli_fetch_assoc($nextsession))
{
if( $row['date'] == DATE(date)){
echo "BOOKINGS TODAY";
} else {
echo "No Bookings";
}
}
?>
</code></pre>
<p>Only error i get at the moment is PHP Warning: Use of undefined constant date - assumed 'date' (this will throw an Error in a future version of PHP)</p>

SKStoreReviewController requestReview() may or may not present and alert? : <p>I'm taking a look at the new <code>requestReview()</code> API that uses <code>SKStoreReviewController</code>. The documents state:</p>
<p>"Although you should call this method when it makes sense in the user experience flow of your app, the actual display of a rating/review request view is governed by App Store policy. Because this method <strong><em>may or may not</em></strong> present an alert, it's not appropriate to call it in response to a button tap or other user action."</p>
<p>Does anyone have any experience using this API. What exactly are the factors that determine if the rating view is shown or not? I'm guessing it's not shown if called too frequently.. Anybody have any insight on this? Thanks!</p>

Email form validation to accept only one domain : <p>I know this is a relatively asked question but here goes. I have registration form where a user can sign up but I want it to be for a closed group of people so only people from my company can register. So only people with @company.com domain addresses can register. What I have so far is just a email validation code using patterns. How would I alter the below code to only allow @company.com emails? Cheers.</p>
<pre><code>$email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';

Add an anchor to Laravel redirect back : <p>In a Laravel controller I have this redirect:</p>
<pre><code> return redirect()->back();
</code></pre>
<p>Which returns me to my previous page (say <a href="http://domain/page" rel="noreferrer">http://domain/page</a>). However, I want to make the page jump to a particular anchor (say #section). So ultimately this page should be opened: <a href="http://domain/page#section" rel="noreferrer">http://domain/page#section</a>. How can I make this happen? I tried appending the anchor to the redirect but that doesn't work. </p>

Why is there some ambiguity in the way sizeof() function works in C++, when using struct : <pre><code>struct node
{
int data;
struct node *next;
}
cout<<sizeof(struct node)<<sizeof(node)<<endl;
//no error, C++ allows us to use sizeof(struct node) and sizeof(node) both.
</code></pre>
<p>Whereas we cannot do the same with int datatype</p>
<pre><code>int a;
cout<<sizeof(int) <<sizeof(a) <<endl;//there is no error here
//BUT
cout<<sizeof(int a) <<endl;//this throws an error
</code></pre>
<p>I understand that "struct node" itself is like a datatype which can be used to declare variable of type "struct node". Going by the behavior of how sizeof() works with int, it is understandable that sizeof(struct node) is equivalent to sizeof(datatype) and hence is correct usage. </p>
<p>But how does sizeof(node) work as well ? It does not throw any error. "node" in itself cannot be used to declare any other variables, it needs to be "struct node" to declare a variable.</p>

Why my gradle projects creates separated modules for main and test in Intellij Idea : <p>Recently, I found all my gradle projects in Idea import separated modules for main and test. The modules look like this:</p>

Display series of images like a gif in Swift : <p>I'm trying to show 100 images frame by frame similar to how a gif would work in my Swift app. Since gifs are not supported in UIImageView, I've read that its best to just switch the images rapidly with code. I've tried doing what some other tutorials say but it all comes up with errors. I'm pretty new to Swift, so I'm quite confused. I know I need to store them in an array of some sort but would some one be able to tell me the exact syntax? And also whatever I need to do in the actual storyboard along with the code.
