I'm trying to insert a rule in the configuration in the JSON configuration file of Visual Studio Code, for the umpteenth time... I don't know, if what I want is possible.

Using "files.exclude" I try to "exclude" all the contents of a directory except a specific directory from the same one I want it to appear.

For example, I don't want the editor's file and directory tree to show me the contents of "views/public/" except its "posts" folder. I have tried with:

"views/public/"      : true, 
"views/public/posts/": false,

I've tried ordering them differently, using wildcards , etc. The exclusive rule always prevails, if I don't "break" it, that is, everything is always hidden or the entire content of "views/public/" is always shown.

Using Visual Studio Code v.1.51.0 on Linux.

When using a display grid, the columns render correctly, at 50% width, with display flex, there is a small "offset".

enter image description here

Why does this occur?

I usually use flexto layout inside other elements, this kind of thing doesn't give me much confidence.

Note: Tested on Chromium / Firefox .

I want to apply custom styles to all elements of a modal. First I try to override all the styles that may come "inherited" for the "modal" class, for example, in case I use Bootstrap.

So I have the following rule:

.modal * {
    all: unset;
}

Now I would give each element of the modal its own styles. Problem: I also load my own styles into other sheets, for example for buttons, so the above rule overrides them. I wish I could apply them without increasing specificity or adding !important to all these styles I'm going to load. For example I would use this HTML for a button (which is under the modal class):

...Sign in

And the CSS for the buttons:

.button-group .btn {
    border-color: grey;
    padding: 1rem;
}
.button-group .btn-primary {
    background: #2196F3;
    border-color: blue;
}


I have tried, without success, to change the startup rule using :not() :

.modal:not(.button-group) * {
    all: unset;
}

.modal *:not(.button-group) {
    all: unset;
}

.modal * :not(.button-group) {
    all: unset;
}

I don't know if it can be done or if there is another way.

I am making a library to use in multiple cases. Initially to add to projects designed with Bootstrap without having to make many changes when "decoupling" Bootstrap , but they would coexist for a while. It may be used with other libraries and with/without Bootstrap , it's just visually based on Bootstrap .

This is the actual code , the HTML is in the "examples" folder.

I've been in a new team for a few days. Reviewing my code, they have indicated that it is not necessary to put void as the return type of a PHP method... and they deleted it...

Why did they add the void return type to the PHP language? what is your function?

In the documentation of migrations in Laravel 5.7 it indicates:

$table->timestamps();
// Adds nullable created_at and  updated_at TIMESTAMP equivalent columns.

$table->nullableTimestamps();
// Alias of timestamps() method.

So I suppose that there is no difference between using one and the other and the second one will have been left over from old versions for compatibility or some other reason.

I know that tags exist, but I've never used them and I haven't met anyone who uses them yet, what are they used for?

From what it says in the Git documentation , it's a way to create a message history , parallel to the commit history to mark only the most important changes, is that it? does it have more uses?

I have a JavaFx application whose main window has several buttons, I have assigned actions to the keys ENTERand ESCAPEwith a code like this:

scene.setOnKeyReleased((KeyEvent keyEvent) -> {
    System.out.println(" -> " + keyEvent.getCode().toString( )); // trace

    if(keyEvent.getCode() == ENTER) {
        // some action here
    }
    if(keyEvent.getCode() == ESCAPE) {
        // some action here
    }
});

The necessary imports are:

import javafx.scene.input.KeyEvent;
import static javafx.scene.input.KeyCode.ENTER;
import static javafx.scene.input.KeyCode.ESCAPE;

I have observed (in Windows) that if the "space bar" is pressed, the keys of the program are successively pressed, I would like to avoid this, that is, leave the pressing of the space key without effect .

Note: In the example code I added a line to trace the key pressed, however the space bar key press is not captured.

Edit: SOLUTION

Building on Gorjesys answer which allows me to detect the key (space bar). The event is marked as consumed to avoid the behavior implemented by default. So the previous code would be:

// importaciones
import javafx.scene.input.KeyEvent;
import static javafx.scene.input.KeyCode.ENTER;
import static javafx.scene.input.KeyCode.ESCAPE;
import static javafx.scene.input.KeyCode.SPACE;

// ...

scene.setOnKeyReleased((KeyEvent keyEvent) -> {
    System.out.println(" -> " + keyEvent.getCode().toString( )); // trace

    if(keyEvent.getCode() == ENTER) {
        // some action here
    }
});
scene.addEventFilter(KeyEvent.KEY_PRESSED, (KeyEvent keyEvent) -> {
    if (keyEvent.getCode() == ESCAPE) {
        // some action here
    }
    if (keyEvent.getCode() == SPACE) {
        keyEvent.consume();
        // NOTE: Marks this Event as consumed to avoid the
        // default behaviour
    }
});

Note: I have moved the detection of the ESCAPE key because sometimes it is not detected by the method I was using ( see question ).

Let's imagine that I have a Stringthat I am going to assign a value to repeatedly within a loop, what would be more efficient to declare it previously and assign a value to it in each interaction or to do it directly within each iteration?

Example A:

String temp;
for (...) {
   temp = algo;

   // hacer algo
}

Example B:

for (...) {
   String temp = algo;

   // hacer algo
}

I am working with Java 8.

I need, having an array of strings whose content I do not know and in which there may or may not be repetitions, to obtain that content, without repetitions and without altering the original order. For example, if I had:

String[] strs = {"orange", "apple", "apple", "banana", "grape", "apple", "lemon"};

Should get:

{"orange", "apple", "banana", "grape", "lemon"};

I currently use the following method to filter repeats, but it tends to mess things up:

/**
 * Filters repeated strings in the array
 *
 * @param  arrStr
 * @return
 */
public static String[] filterRepeatedStr(String[] arrStr) {

    List<String> arr = Arrays.asList(arrStr);
    Set<String> hs   = new HashSet();
    hs.addAll(arr);

    return hs.toArray(new String[hs.size()]);
}

How can I insert special characters inside a JSON? For example if I have:

{
    "a": "Hola mundo"
}

and I want to put the word "world" in quotes. I tried escaping them and with the HTML code: "I show the string in a web page, but neither of the two options worked, I don't know if it's because of the library that loads it or it's something inherent to the use of JSON.

Edited:

Escaped quotes:\"

Didn't properly phrase the question. I see that my problem is with the ngx-translate library for Angular2 , not with the JSON itself. This library stores the translations in a JSON file, but it has not allowed me to insert double quotes inside them as I have indicated before.

If I have three branches master , develop and xxx . Is there a way to find out from commands which branch part xxx ? And since we are, which branches start from a certain branch?

edited

What I would like to know is if you can ask for a specific branch or if you can get a list of branches like:

master
master/develop
master/develop/xxx
master/develop/zzzzz
master/new-fonts

to see it easily.

I have an integer that I divide by 100, displaying the result on the screen, from which I can get output like:

91,32
5,22
11,5

I need to always have two decimal places, so I fill with zeros in case I only have 1, to obtain for example:

91,32
5,22
11,50

To get the decimals I convert the initial integer to a float, that is, I am doing something like this:

int i = 150;
float res, f = (float) i;
res = f / 100;

System.out.println( res );

Edited: For the sake of clarity, I'm going to use it in a program that shows output like this:

Contenido total: 126,59€
Hay 49 monedas de 1 cent. Con un valor de: 0,49€
Hay 45 monedas de 2 cent. Con un valor de: 0,90€
Hay 10 monedas de 5 cent. Con un valor de: 0,50€
Hay 14 monedas de 10 cent. Con un valor de: 1,40€
Hay 39 monedas de 20 cent. Con un valor de: 7,80€
Hay 13 monedas de 50 cent. Con un valor de: 6,50€
Hay 27 monedas de 100 cent. Con un valor de: 27,00€
Hay 41 monedas de 200 cent. Con un valor de: 82,00€

Although I had not included it in the question originally, the integer part is also required, even if it has the value 0, that is, ,40it would not be valid, it would require: 0,40.

I am doing some cryptography tests, by executing the following line of code:

Signature sgn = Signature.getInstance( "MD5" );

I get the error:

java.security.NoSuchAlgorithmException: MD5 Signature not available

I have tried SHA, SHA256, ... It is always the same, when in other cases it did not fail, for example:

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.security.Signature;

public class TestAlgoriths {

    public static void main( String [] args ) {
        
        try {
            MessageDigest msgDg = MessageDigest.getInstance( "MD5" );
            
        } catch (NoSuchAlgorithmException e) {
            System.err.println(
                "ERR -> Generando MessageDigest... \n" + e.toString( ));
        }
        
        try {

I was analyzing some bookstores and the doubt arose. It is common for them to contain a "src" directory, I guess it comes from "source", but I'm not sure if that is the case and if it is because of the abbreviated form... It is not always used either and I don't know if it is common to find it in some particular architectural pattern. I guess he'll have his story, anyone shed some light on it?

Let's say I have created two branches (apart from the main one), I'll call them branch-a and branch-b .

I am making commits in both branches and at a given moment I want to transfer the changes of a commit from branch-a to branch-b , changes that affect a specific file, how can I do this?

I'm doing some regression testing looking for a bug I introduced in a project, basically cloning the current repository, removing x commits and testing to see where the bug appeared... I wanted to explore other alternatives.

The usual thing is to create new branches from the current moment of work in the repository and at this moment I wish I had created a new branch x commits ago... Since I didn't, I would like to know if it is possible to create a new branch from a given commit , for example from 4 commits ago... any way to do it?

I have come across some Java code that I don't know how to interpret.

The part that I have marked I do not know what it is, it does not reach me with the knowledge that I have.

Any reference so I can look it up?

enter image description here

Code:

package hibernate1;
import org. hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class SessionFactoryUtil {

private static final SessionFactory sessionFactory;
        static { 
            try { 
                sessionFactory = new Configuration()
                                .configure()
                                .buildSessionFactory();
            } catch ( Throwable ex ) { 
                System.err.println( 
                    "Err iniciando SessionFactory: " + ex

            } 
        } // static

    public static SessionFactory getSessionFactory() {

        return sessionFactory;
    } 
}

I don't understand the structure. Declare the property sessionFactory, and then there's a block static, I don't know what that is.
