React JS Error: Invalid attempt to destructure non-iterable instance : <p>I have a sort filter that takes an array to populate the options. Trying to see the option <code>value</code> equal to the text within the array but I get the error within the title: </p>

Do I need to escape dash character in regex? : <p>I'm trying to understand dash character <code>-</code> needs to escape using backslash in regex?</p>
<p>Consider this:</p>
<pre><code>var url = '/user/1234-username';
var pattern = /\/(\d+)\-/;
var match = pattern.exec(url);
var id = match[1]; // 1234
</code></pre>
<p>As you see in the above regex, I'm trying to extract the number of id from the url. Also I escaped <code>-</code> character in my regex using backslash <code>\</code>. But when I remove that backslash, still all fine ....! In other word, both of these are fine:</p>
<ul>
<li><a href="https://regex101.com/r/sJ5mX4/1" rel="noreferrer"><code>/\/(\d+)\-/</code></a></li>
<li><a href="https://regex101.com/r/sJ5mX4/2" rel="noreferrer"><code>/\/(\d+)-/</code></a></li>
</ul>
<p>Now I want to know, which one is correct <em>(standard)</em>? Do I need to escape dash character in regex? </p>

filter syntax where some items may or may not be selected : <p>I've got 3 dropdown boxes on my asp.net form: Country, State and City. I want to use these to filter my data. However, I also want the user to have the ability to not use the filters, or not use <em>all</em> the filters.</p>
<p>For instance, they may not want to filter at all. Or they may only want to filter by Country. Or only by Country/State. Or, if it's not the US, then by Country/City.</p>
<p>I'm stuck on how to write this. Right now I have:</p>
<pre><code> SqlDataAdapter adapter = new SqlDataAdapter("Select * from [MOS_Role] where [Country_ID] = @CoID AND [State_ID] = @StID AND [City_ID] = @CiID ORDER BY [Role] ASC", con2);
adapter.SelectCommand.Parameters.AddWithValue("@CoID", Convert.ToInt32(ddlCountry.SelectedValue));
adapter.SelectCommand.Parameters.AddWithValue("@StID", Convert.ToInt32(ddlState.SelectedValue));
adapter.SelectCommand.Parameters.AddWithValue("@CiID", Convert.ToInt32(ddlCity.SelectedValue));
</code></pre>
<p>but that doesn't work when you leave a dropdown unselected.</p>

Why can't I declare a thread in an if in C++? Is there a way around? : <p>I am trying to use threading in an if statement. </p>

void someFunction() {/*someTask*/}
void main() {
bool isFirstRun = true;
while(true){
if(isFirstRun==false){std::thread t1(someFunction);}

//some tasks here
t1.start();
//some tasks here

Python subprocess .check_call vs .check_output : <p>My python script (python 3.4.3) calls a bash script via subprocess:</p>
<pre><code>import subprocess as sp
res = sp.check_output("bashscript", shell=True)
</code></pre>
<p>The <strong>bashscript</strong> contains the following line:</p>
<pre><code>ssh -MNf somehost
</code></pre>
<p>which opens a shared master connection to some remote host to allow some subsequent operations.</p>
<p>When executing the python script, it will prompt for password for the <code>ssh</code> line but then it blocks after the password is entered and never returns. When I ctrl-C to terminate the script, I see that the connection was properly established (so <code>ssh</code> line was successfully executed).</p>
<p>I don't have this blocking problem when using <code>check_call</code> instead of <code>check_output</code>, but <code>check_call</code> does not retrieve stdout. I'd like to understand what exactly is causing the blocking behavior for <code>check_output</code>, probably related to some subtlety with <code>ssh -MNf</code>.</p>

Correct way to change a list of strings to list of ints : <pre><code>dict = {0: ['2', '6'], 1: ['2'], 2: ['3']}
print("Original: ")
print(dict)

vals = [int(s) for s in vals]
print("New: ")
print(dict)

New:
{0: ['2', '6'], 1: ['2'], 2: ['3']}

<p>I can't figure why the list of values is not changing, I have tried the map() function and it also does not work, any reason why?</p>

<pre><code>1 2 3 4 5 6 7 8 9 10

<p>Basically, the generator just dies after a single execution.</p>
<p>I know that the fact that a generator can only be used once is something built into Python, but why is it like this? Is there a specific reason to only allowing a generator object to be executed once?</p>

Django: How to rollback (@transaction.atomic) without raising exception? : <p>I'm using Django's command to perform some tasks involving database manipulation:</p>
<pre><code>class SomeCommand(BaseCommand):
@transaction.atomic
def handle(self, *args, **options):
# Some stuff on the database
</code></pre>
<p>If an exception is thrown during execution of my program, <code>@transaction.atomic</code> guarantees rollback. Can I force this behavior without throwing exception? Something like:</p>
<pre><code># Doing some stuff, changing objects
if some_condition:
# ABANDON ALL CHANGES AND RETURN
</code></pre>

Does a return statement end a method? : <p>Let's say I have a method, for instance, the one I'm working on is a boolean <em>Empty</em> method, that simply returns false if the list (technically it's a stack using linked lists) is empty, and returns true if it has values. </p>
<p>I have an if statement that returns false if the first value of the list is null (considering it's a stack) and returns true if it has values.
Here is that method in my code:</p>
<pre><code>public boolean empty(){
if(list.getFirst() == null){
return false;
}
else{
System.out.println("Stack has values.");
}
return true;
}
</code></pre>
<p>my question is, if I have determined that the list is empty and return false, will the method end there? Or, in other words, does a method stop doing things once it gets a return message?</p>

Golang: get a slice of tuples (hour, minute) : I've got a problem that I couldn't resolve.
I've got a list of minutes:
minutes := int{0, 30} // Minutes are 0 and 30
And a four parameters: `start`, `startBreak`, `stop`, `stopBreak`:
start := types.NewTuple(9, 30) // It represents "9:30"
startBreak := types.NewTuple(12, 0) // It represents "12:00"
stop := types.NewTuple(21, 0) // It represents "21:00"
stopBreak := types.NewTuple(14, 30) // It represents "14:30"
I want to get a slice of tuples `(hour, minutes)` using all the minutes in the `minutes` slice and they must not be included in the range `startBreak-stopBreak` (it can be equal to `startBreak` or `stopBreak`, so the range will become `12:30, 13:00, 13:30, 14:00`) and `stop-start` (it can be equal to `start` and `stop`, so the range will become `21:30, 22:00, 22:30, ..., 8:30, 9:00`).
For example, using those four parameters, the final result will be:
9:30, 10:00, 10:30, 11:00, 11:30, 12:00, 14:30, 15:00, 15:30, 16:00, 16:30, 17:00, 17:30, 18:00, 18:30, 19:00, 19:30, 20:00, 20:30, 21:00
Thank you all!

Initialize new Hash Table, pointers issue : <p>I have this exercise for homework that follows:</p>
<p>Consider the following definition to represent dynamic hashtables with collision treatment chaining.</p>
<pre><code>typedef struct entry{
char key[10];
void *info;
struct entry *next;
} *Entry;
typedef struct hashT{
int hashsize;
Entry *table;
} *HashTable;
</code></pre>
<p>Define `HashTable newTable(int hashsize)
note that the memmory necessary must be allocated and that all table entrys must be initialized with empty list.</p>
<p>My proposition is this:</p>
<pre><code>HashTable newTable(int hashSize){
Entry *table = malloc(sizeof((struct entry)*hashSize));
HashTable *h = malloc(sizeof(struct hashT));
h->hashSize = hashSize;
h->table = table;
return h;
}
</code></pre>
<p>im pretty sure the logic is correct. my problem is with pointers. for example, sometime I see (char *), or in this case (table *) before the malloc function... Is this necessary?</p>
<p>and for the return, should I return h, or *h? and whats the difference?</p>
<p>thank you</p>

Don't really understand the $_SESSION variable : I'm trying to create a login form (new to php and coding) and I made it work but I don't exactly understand what I'm doing in my code and would love to understand it. I included notes about what I understand and what I dont understand in my code.
1.Anyways, my main problem is with the "$_SESSION['umsco'] = $username" why do you need to apply the $username variable to it for it to work?
2.I don't really understand the $result thing in general.
Thank you to anyone who is willing to help me in advance, it's honestly appreciated.
```php
// I include the database file so we can get the information from there and apply it in here as well.
include "dbc.php";
// here we select the variables we want from the table 'members'.
$sql = "SELECT id, firstName, lastName FROM members";
// here we do something that I dont really know but this is standard procedure.
$result = mysqli_query($conn, $sql);
// declaring username
$username = $_POST["username"];
$password = $_POST["password"];
// my result thing, again, standard procedure.
$result = $conn->query($sql);
// we insert all values in row, standard procedure.
$row = $result->fetch_assoc();
// here we check if the username is the same as the database.
if ($username == $row["firstName"]) {
// if it's correct then we start a session
session_start();
// we give a session some random letters or numbers and set it to $username, not exactly sure why, but it wont work without it.
$_SESSION['umsco'] = $username;
// we change the location to secrect.php
header("location: secret.php");
}
// we close the connection, not sure if this is needed, but it seems logical.
$conn->close();

Read for inputs individualy [C] : I want to read inputs individually, that means that I enter a character, press enter and then ask for the second input. The problem is that when the program asks me to input the character it asks for both at the same time.
This is my code:
#include <stdio.h>
int main(){
printf("Enter a character \n");
char a = 0;
a = getchar();
printf("You entered: %c \n",a);
putchar(a);
printf("\n");
char b[2];
puts(b);
gets(b);
printf("You entered: %c \n",b[0]);
puts(b);

Calling a void method to a static main method : I've been trying to call a void method to my static main method for about two hours now. Here's what I have:
public static void main(String[] args){
Scene scene = new Scene();
Animate animate = new animate();
animate(); //I've tried it by itself, but no luck
}
public void animate(){
sun.slowMoveHorizontal(5000);
moon.slowHorizontal(400);
}
If anyone could help it would be much appreciated. The text says, "Add a call to animate in your main method just below the line that creates the Scene object." If that helps. Maybe I'm just dumb.

objective c NSArray to NSString : Server side is java:
First create a string 'Hello world.' for example, and then use java code to convert this string to be a byte array, then send to ios client.
My ios client use NSStream to read the data, and got the array.
Now I want to convert this array to be the string 'Hello world'.
How to do that?
I have tried to convert the array to nsdata and then to nsstring, but it fails.
And also I try to convert the array to a string ,but it seems to convert the number in array to be a string number instead of my expected string 'Hello world'.

Spring Boot Admin: No option to refresh configuration : <p>I am trying to integrate spring-boot-admin with an existing project which is using actuator and spring cloud config server. I am able to change the external property file and send a post request to <strong>/refresh</strong> endpoint from postman. It works fine and I can see updated value in client app. I have disabled all security for actuator endpoints for now to try spring-boot-admin. My problem is that, I can not see any option to change and refresh configuration in spring-boot-admin UI. I have created an issue but there is no update as of now so thought of sharing this problem here. All the details are available here. Does anyone have any idea what I have missed?</p>

I keep getting this error: SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: YES) And I don't know how to fix it.
I have installed mysql, apache2, php and phpmyadmin. Then I've changed a few things in the .htaccess file and changed AllowOverride from none to all (not sure where I did this again). That's all I've done with the server. I read people talking about databases, but I've only got 1 DB.
Please help someone, would be really appreciated. If my information is too shitty, make sure to reply. I will respond as fast as possible.

HomeKit - Changing Lightbulb Color Without Transition : <p>I am making an app that uses HomeKit enabled lights for notifications. When I write a new value to the hue characteristic of a lightbulb, the color is transitioned from it's current hue to the hue written. So instead of going from it's currently color (let's say Red) immediately to the written color (let's say Purple) it goes from Red, Pink to Purple as well as all the "in between" colors.</p>
<p>How can I <em>immediately</em> change the color of a HomeKit Enabled lightbulb from one color to the next without this transition?</p>

Can you use @ViewChild() or similar with a router-outlet? How if so? : <p>I repeatedly run into a situation where I'd like to access a child component existing on the other side of a router outlet rather than a selector:</p>
<pre><code>Like:
<router-outlet></router-outlet>
NOT:
<selector-name></selector-name>
</code></pre>
<p>This conflicts with the ViewChild functionality as I know it, yet it seems like my component should be able to see and interact with what's inside that router-outlet just as easily as with what's inside a selector-tag.</p>
<p>For instance I tried this:</p>
<pre><code>export class RequestItemCatsComp {
@ViewChild('child') child: RequestItemsComp;
***etc...***
ngAfterViewInit() {
if (this.child) // Always child is undefined
this.groupId = this.child.groupId;
}
}
</code></pre>
<p>But naturally, <strong>child is undefined</strong> because this is the wrong way. Is there a right way?</p>
<p>I'm trying to use a service to share the data but then run into another problem "expression has changed after it was checked" which I'm hoping to remedy without a hack or enabling prod mode.</p>

<p>I notice this problem when testing the application using performance test. The test shows that the login request needs huge time to get response. The following figure shows result of performance test for the login request:

Best way to handle false unused imports in intellij : <p>Intellij falsely marked some import of Scala implicits as not being use.
Is there a way to prevent it from deleting those import when optimized them explicitly for a specific import and not prevent optimized import for the entire project ? </p>

what does VOLUME command do in Dockerfile? : <p>I am having it difficulty in understanding added advantage of VOLUME(<a href="https://docs.docker.com/engine/reference/builder/#volume" rel="noreferrer">https://docs.docker.com/engine/reference/builder/#volume</a>) . </p>
<p>In Dockerfile one can have mkdir to create a directory. Once the directory is created we can have handle to it. why specify a VOLUME (mount)and assign to that directory? What advantage VOLUME mount gives? I am trying to understand here without VOLUME what will we miss. </p>
<p>to me its looks like a redundant function , however I might be wrong.</p>

ionic 2 error cordova not available : <p>I am trying to use the cordova GooglePlus plugin in a new ionic 2 project (latest ionic2 version) but I always run into errors regarding cordova.
The plugin is properly installed and shows up in the plugin folder.</p>
<p>One approach I tried is this:</p>
<pre><code>import { GooglePlus } from "ionic-native";
</code></pre>
<p>and then</p>
<pre><code>GooglePlus.login().then(...)
</code></pre>
<p>The login method executes but always throws an error saying <code>"cordova_not_available"</code></p>
<p>I want to test the app with <code>ionic serve</code> on my windows system first before deploying it to my android phone.
How can I make cordova available in the localhost server? From searching I understand that cordova.js is generated and always included in the deploy package for the device.</p>
<p>Another approach I tried is using</p>
<pre><code>window.plugins.googleplus.login(...)
</code></pre>
<p>But this approach does not go through the typescript compiler who does not know anything about a plugins property on the windows object.</p>
<p>How can I fix this?</p>
