Colon after method declaration? : <pre><code>public function getRecords(int $id): array;
</code></pre>
<p>Hi, can someone tell me what colon is doing here, in this method declaration inside PHP interface? Is this PHP 7 syntax and what array is meaning here? Method must return array or something else? </p>

is there an easy way to find a most similar keyword out of an array using javascript? : javascript, find a reslut most like with search text in array
example
var testData = [
'101',
'102C',
'103B',
'A',
'BD',
'AB',
'A102B',
'A1',
];
//if search Text is 102
var searchText = "102";
// result should be 102C
//if search Text is 102B
var searchText = "102B";
// result should be A102B, 102C
//if search Text is A
var searchText = "A";
// result should be A, A1, AB, A102
is there an easy way to find a most like keyword out of an array using javascript?
Thank you.

Java, declaring static methods in interface : <p>This subject already has questions and answers, none with conclusive results. If this is not possible, then can someone determine the best workaround?
Some of the answers say that this is possible with Java 8, but my IDE (eclipse) is still showing errors even though it is set to compiler compliance 1.8. If someone can get it to work on their system, let me know and I'll fix the problems with my system.</p>
<p>Problem: I need to create an interface with both static and non-static methods. An example of this:</p>
<pre><code>// I need to create an interface with both static and non-static methods.
public interface TestInterface {
// No problem
int objectMethod();
// static is an illegal modifier in an interface
static int classMethod();
}
// TestClass is one of many classes that will implement the interface.
public class TestClass implements TestInterface {
// static and non-static variables are no problem
private int objectVal;
public static int classVal;
// this method has no problem
public int objectMethod() {
return objectVal;
}
// this one has problems because it implements a method that has problems
public static int classMethod() {
return classVal;
}
}
</code></pre>
<p>And I need a class that will use classes that implement the interface</p>
<pre><code>// a class that will use classes that implement from the interface
// what is the syntax for this? my IDE doesnt like the implements keyword
public class TestGeneric <T implements TestInterface> {
// stored instances of the class
private T t;
public void foo() {
System.out.printf("t's value is: %d\n", t.objectMethod());
System.out.printf("T's value is: %d\n", T.classMethod());
}
}
</code></pre>
<p>The only problems in the above code are with the static methods. The only workaround I can think of is to not declare any methods as static, but use them in the way most similar to static use.</p>

Python 2.7.12- How to have the same length for a new string as well as letters? : <p>I've just started learning Python 2.7.12 and in my first homework I was given a string called str2, and I'm supposed to create another string which will be the same length as the previous one. In addition,I need to check the third letter (if it's an Upper I need to convert to lower and the opposite, as well as if it's not a letter, I need to change it with '%').
The other characters of the first string should be copied to the second one.</p>
<p>We were given just the basic commends and nothing else so I can't really solve it. please help me! :)</p>

How to return a vector from a class into another class : <p>I'm trying to use arrays with java and when i return the array froma class it prints [I@7d4991ad (that should be the address), but how to return all the elements?</p>
<p>(by the way, I always mess with JavaScript and Java and I don't know which one eclipse is, I apologize)</p>
<p>Basically I did a return of the name of the vector with the metod int[]</p>
<pre><code>public class TestVettori {
private int vector[];
private int length;
//function input lengt
public void setLength(int newLung) {
if(newLung>=1)
length=newLung;
}
//function input
public void inputValue(int[] vett) {
vector = new int [length];
for(int i=0;i<length;i++)
vector[i]=vett[i];
}
//function print array
**public int[] getVector() {
return vector;
}**
}
</code></pre>
<pre><code>import java.util.Scanner;
public class ProgTestVettori {
public static void main(String[] args) {
Scanner in= new Scanner (System.in);
int lung ;
int vett[];
TestVettori vector;
System.out.println("Put the length of the array");
lung = in.nextInt();
vett = new int [lung];
vector = new TestVettori();
vector.setLength(lung);
for(int i=0;i<lung;i++) {
System.out.println("Input the"+(i+1)+" number");
vett[i]=in.nextInt();
}
vector.inputValue(vett);
**for(int i=0;i<lung;i++) {
System.out.println("the "+(i+1)+"° number is"+vector.getVector());
}**
in.close();
}
}
</code></pre>
<p>I pasted all the code so you can see all of it:
I put the length, let's suppose 3
i put numbers and i should expect numbers from the console, but i get 3 times
[I@7d4991ad the address...</p>

C# Writing a file to the APP_DATA folder and getting bitdefender (antivirus) to scan/delete it : This is the code I use to write my file to the app_data folder:
var filename = Server.MapPath("~/App_Data") + "/" thefilename;
var ms = new MemoryStream();
file.InputStream.CopyTo(ms);
file.InputStream.Position = 0;
byte[] contents = ms.ToArray();
var fileStream = new System.IO.FileStream(filename, System.IO.FileMode.Create,
System.IO.FileAccess.ReadWrite);
fileStream.Write(contents, 0, contents.Length);
fileStream.Close();
This writes the file fine however bitdefender does not delete this file if there is a virus on it unless I go on the IIS and manually try to open/move the file, if I do that then it is instantly deleted.
If I copy and paste the test virus file into the app_data folder directly then bitdefender removes it instantly.
I have tried to use various ways to read/move the file with System.IO.File.Move/Open/ReadAllLines
Yet nothing triggers bit defender to remove the file.
The only thing I got to work was creating a new process to open the file, however I don't want to be doing that on the server and I am looking for a different solution. This is the code that does this:
Process cmd = new Process();
cmd.StartInfo.FileName = filename;
cmd.Start();
A solution with System.IO.File.Open would be best for me in this situation but I cannot figure out why it isn't working. | 0debug |
Raycast in Three.js with only a projection matrix : <p>I'm rendering some custom layers using Three.js in a Mapbox GL JS page following <a href="https://docs.mapbox.com/mapbox-gl-js/example/add-3d-model/" rel="noreferrer">this example</a>. I'd like to add raycasting to determine which object a user has clicked on.</p>
<p>The issue is that I only get a projection matrix from Mapbox, which I use to render the scene:</p>
<pre class="lang-js prettyprint-override"><code>class CustomLayer {
type = 'custom';
renderingMode = '3d';
onAdd(map, gl) {
this.map = map;
this.camera = new THREE.Camera();
this.renderer = new THREE.WebGLRenderer({
canvas: map.getCanvas(),
context: gl,
antialias: true,
});
this.scene = new THREE.Scene();
// ...
}
render(gl, matrix) {
this.camera.projectionMatrix = new THREE.Matrix4()
.fromArray(matrix)
.multiply(this.cameraTransform);
this.renderer.state.reset();
this.renderer.render(this.scene, this.camera);
}
}
</code></pre>
<p>This renders just great, and tracks changes in view when I pan/rotate/zoom the map.</p>
<p><a href="https://i.stack.imgur.com/iQXGc.png" rel="noreferrer"><img src="https://i.stack.imgur.com/iQXGc.png" alt="A cube on Liberty Island"></a></p>
<p>Unfortunately, when I try to add raycasting I get an error:</p>
<pre class="lang-js prettyprint-override"><code> raycast(point) {
var mouse = new THREE.Vector2();
mouse.x = ( point.x / this.map.transform.width ) * 2 - 1;
mouse.y = 1 - ( point.y / this.map.transform.height ) * 2;
const raycaster = new THREE.Raycaster();
raycaster.setFromCamera(mouse, this.camera);
console.log(raycaster.intersectObjects(this.scene.children, true));
}
</code></pre>
<p>This gives me an exception:</p>
<pre><code>THREE.Raycaster: Unsupported camera type.
</code></pre>
<p>I can change from a generic <code>THREE.Camera</code> to a <code>THREE.PerspectiveCamera</code> without affecting the rendering of the scene:</p>
<pre class="lang-js prettyprint-override"><code>this.camera = new THREE.PerspectiveCamera(28, window.innerWidth / window.innerHeight, 0.1, 1e6);
</code></pre>
<p>This fixes the exception but also doesn't result in any objects being logged. Digging a bit reveals that the camera's <code>projectionMatrixInverse</code> is all <code>NaN</code>s, which we can fix by calculating it:</p>
<pre class="lang-js prettyprint-override"><code> raycast(point) {
var mouse = new THREE.Vector2();
mouse.x = ( point.x / this.map.transform.width ) * 2 - 1;
mouse.y = 1 - ( point.y / this.map.transform.height ) * 2;
this.camera.projectionMatrixInverse.getInverse(this.camera.projectionMatrix); // <--
const raycaster = new THREE.Raycaster();
raycaster.setFromCamera(mouse, this.camera);
console.log(raycaster.intersectObjects(this.scene.children, true));
}
</code></pre>
<p>Now I get two intersections wherever I click, with two faces of the cube. Their distances are 0:</p>
<pre><code>[
{ distance: 0, faceIndex: 10, point: Vector3 { x: 0, y: 0, z: 0 }, uv: Vector2 {x: 0.5, y: 0.5}, ... },
{ distance: 0, faceIndex: 11, point: Vector3 { x: 0, y: 0, z: 0 }, uv: Vector2 {x: 0.5, y: 0.5}, ... },
]
</code></pre>
<p>So clearly something isn't working here. Looking at the <a href="https://github.com/mrdoob/three.js/blob/441fefadc017ebafd2d10089b6d48e1cd28795c2/src/core/Raycaster.js#L81-L83" rel="noreferrer">code for <code>setCamera</code></a>, it involves both <code>projectionMatrix</code> and <code>matrixWorld</code>. Is there a way I can set <code>matrixWorld</code>, or construct the raycaster's ray directly using only the projection matrix? It seems that I only need the projection matrix to render the scene, so I'd hope that it would also be all I need to cast a ray.</p>
<p>Full example <a href="https://codepen.io/danvk/pen/GRggjmg?editors=0010" rel="noreferrer">in this codepen</a>.</p>

How To Use ScrollMagic with GSAP and Webpack : <p>In order to use <a href="http://scrollmagic.io/examples/basic/simple_tweening.html">ScrollMagic with GSAP</a>, you need to load the <code>animation.gsap.js</code> plugin. With Webpack you would do something like this to accomplish that (assuming you use the CommonJS syntax and installed everything with npm):</p>
<pre><code>var TweenMax = require('gsap');
var ScrollMagic = require('scrollmagic');
require('ScrollMagicGSAP');
</code></pre>
<p>To make sure that this actually works, you have to add an alias to your Webpack configuration, so that Webpack knows where the plugin lives.</p>
<pre><code>resolve: {
alias: {
'ScrollMagicGSAP': 'scrollmagic/scrollmagic/uncompressed/plugins/animation.gsap'
}
}
</code></pre>
<p><strong>Unfortunately</strong>, ScrollMagic keeps throwing an error, when you are using this configuration and the CommonJS syntax like above.</p>
<pre><code>(ScrollMagic.Scene) -> ERROR calling setTween() due to missing Plugin 'animation.gsap'. Please make sure to include plugins/animation.gsap.js

How to compile all included files into one using Babel? : <p>I am using Babel in my project. The thing is, I have this line of code in my <code>server.js</code>:</p>
<pre><code>import schema from "./data/schema";

<p>(<code>data/schema.js</code> is in ES2015 syntax).</p>
<p>And when I am trying to compile my <code>server.js</code> with babel, like this:</p>
<pre><code>babel -o server_production.js --minified server.js
</code></pre>
<p>it produces a new file without errors and replaces <code>import</code> instruction with <code>require</code>. But the thing is, when I am trying to run my babel-compiled <code>server.js</code> with <code>node</code>, it complains about <code>data/schema.js</code>, because it wasn't transpiled into ES5, only required (the exact error is <code>Unexpected token "import"</code>, because I am using some other imports in <code>data/schema.js</code>).</p>
<p>So, the question is: how can I compile my file and all the files it <code>import</code>s into one file? I tried <code>babel -o server_production.js --minified data/schema.js server.js</code>, but that didn't work either.</p>

"Solving Environment" during `conda install -c <my_channel> tensorflow` takes 3+ min but changing the name a bit reduces the time significantly : <p>I am writing a custom conda package for tensorflow. When I name the package "tensorflow" it takes it more than 3 minutes to get past the "solving environment" part but if I change the package name even a little bit, to "tensorflowp3" it loads in around 10 seconds.
I am using the commands - </p>
<p><code>conda install -c <my_channel> tensorflow</code></p>
<p><code>conda install -c <my_package> tensorflowp3</code></p>
<p>I am not sure why setting a slightly different package name causes such a significant time change. I am specifying which channel the package should be loaded from in the command as well. I have tried doing the same with locally stored packages using the --use-local tag as well but it still behaves the same way as with the channel name. Any help would be very appreciated. </p>

Switching between file paths in Java : <p>I am writing a mergesort for an externalsort, which reads 2 chunks of data at a time from a file A, merges them into a larger chunk, and writes it to a file B. After this, I need to then read 2 of these increased chunks at a time from file B, merge them into 1 larger chunk, and write this to file A. This switching goes on until all the data counts as 1 chunk at the end. </p>
<p>I have tried swapping the identifiers around like this after each iteration:</p>
<pre><code>RandomAccessFile temp = fileA;
fileA = fileB;
fileB = temp;
</code></pre>
<p>This requires, that I update the BufferedInput and BufferedOutputStreams with the new file directory names and construct them each time. </p>
<p>I have a limited amount of RAM, so I cannot keep creating new objects unless I have to. Is there a better way to switch the target file and source file each iteration? </p>

cbind 2 dataframes with different number of rows : <p>I have two lists named <code>h</code> and <code>g</code>.
They each contain 244 dataframes and they look like the following:</p>
<pre><code>h[[1]]
year avg hr sal
1 2010 0.300 31 2000
2 2011 0.290 30 4000

6 2015 0.330 26 7000
7 2016 0.315 40 9000
g[[1]]
year pos fld
1 2010 A 0.990
2 2011 B 0.995
3 2013 C 0.970
4 2014 B 0.980
5 2015 D 0.990
</code></pre>
<p>I want to <code>cbind</code> these two dataframes.
But as you see, they have different number of rows.
I want to combine these dataframes so that the rows with the same year will be combined in one row. And I want the empty spaces to be filled with <code>NA</code>.
The result I expect looks like this:</p>
<pre><code> year avg hr sal pos fld
1 2010 0.300 31 2000 A 0.990
2 2011 0.290 30 4000 B 0.995
3 2012 0.275 14 600 NA NA
4 2013 0.280 24 800 C 0.970
5 2014 0.295 18 1000 B 0.980
6 2015 0.330 26 7000 D 0.990
7 2016 0.315 40 9000 NA NA
</code></pre>
<p>Also, I want to repeat this for all the 244 dataframes in each list, <code>h</code> and <code>g</code>.
I'd like to make a new list named <code>final</code> which contains the 244 combined dataframes.</p>
<p>How can I do this...?
All answers will be greatly appreciated :)</p>

console.log(add(1,2))

Here is this 'value'. I understand what it does. But what is it, </br>
and where did it come from. How can I use it in general? </br>
counter.set = value => count = value;
counter.decrease = () => count--;

let counter = makeCounter();
alert( counter() ); // 0
alert( counter() ); // 1
// Also here. What kind of 'set' is this? </br>
I've seen one in Map.prototype.set(), but there is no Map here. </br>
counter.set(10); // set the new count
alert( counter() ); // 10
counter.decrease(); // decrease the count by 1
alert( counter() ); // 10 (instead of 11)

How do I store a Swift Struct in Core Data on iOS? : <p>At the moment I'm storing one of my classes as NSData in a plist and obviously that isn't a good way to do it.</p>

<pre><code>import Foundation
import CoreData
class Favourite: NSManagedObject {
@NSManaged var origin: Stop
struct Stop {
var name: String;
var id: String;
}
}
</code></pre>
<p>But this is no good because it says</p>
<p><em>Property cannot be marked as @NSManaged because its type cannot be represented in Objective-C</em></p>
<p>Furthermore, if this error did not occur, I don't know what I'd set it up as in my xcdatamodeld file.</p>
<p>I guess I could store the values in the struct and assign on initialisation of the object? Is this the most optimal/clean way?</p>

ERROR: Unexpected action: build

xcode_workspace: Project.xcworkspace
xcode_scheme: ProjectTests

<p>Perhaps I missed something in the tutorial? I got a little lost on the pods dependency section but I believe I did it right. This happens with a new scheme (ProjectTests) created and with the original scheme (Project). I added the dependencies for the ProjectTests scheme in the Build phase like it said but still no dice. Any ideas?</p>

I get a really strange error when I try to run a very simple program : "Unhandled exception at 0x0F29F365 (msvcr120d.dll) in HW2_1_JM.exe: 0xC0000005: Access violation reading location 0xFFFFFFFF."
This is my first post, and that is the error I consistently get when I attempt to run this program. I'm new to programming, so I'm sorry for my code quality. My mom couldn't figure out what it was. When it's not throwing this error, it's simply pausing endlessly before the while. We think the error is with "int d" because when we tried to print both n and d we get the error again after printing n.
int main()
{
int a[10];
puts("Please input a value: \n");
int n;
scanf("%i", &n);
printf("\n you chose: %i\n", n);
puts("Please input a base value, between 1 and 11: \n");
int d;
scanf("%i", &d);
while (!(n = -1));
{
int q = n;
int k = 0;
printf(q);
while (q != 0);
{
a[k] = (q % d);
q = q / d;
printf(q);
k++;
}
for (int j = 0; j < 11; j++)
{
printf("Element [%d] = %d \n", j, a[j]);

How about 30~ish BizTalk applications, good practice? : <p>Trying to introduce BTDF for deployment, having a legacy of 30ish solutions, with the principle of 1:1 mapping between solution and biztalk application, this will result in 30ish BizTalk applications deployed. Never did this or saw this before, would this consider a bad practice or does it impact performance in any sense?</p>
<p>If this is not a good way to go for deployment, could you please suggest a better way to deploy without major refactor the solutions?</p>
<p>Thanks!</p>

how do I store data in an array if the data is more than 1? : My script like this :
let data = [
{day: 1, time: '08:00', note: 'madrid'},
{day: 2, time: '08:00', note: 'barcelona'},
{day: 3, time: '10:00', note: 'juventus'},
]
let days = [7, 1, 2, 3, 4, 5, 6]
let list = []
days.forEach(element => {
let item = data.find(x => x.day === element)
if (item) {
list.push(item)
} else {
list.push({ day: element, time: undefined })
}
})
If the script executed, it works. It will show schedule from day 1 to day 7
But my problem is variable data is dynamic. So 1 day can have more than 1 schedule. So the variable data can like this :
let data = [
{day: 1, time: '08:00', note: 'madrid'}, {day: 1, time: '09:00', note: 'chelsea'},
{day: 2, time: '08:00', note: 'barcelona'}, {day: 2, time: '09:00', note: 'mu'},
{day: 3, time: '10:00', note: 'juventus'}
]
maybe i should make an array inside key day. so I can save data days that are more than 1 schedule. how do i do that? | 0debug |
AWS Cognito Authentication USER_PASSWORD_AUTH flow not enabled for this client : <p>I have an mobile app with user pool (username & password). The app works fine with aws-amplify sdk. But, wanted to move the code out to Lambdas. So, I have written the following Lambda using Boto3.</p>
