Javascript: false && false is false? : <p>So, I've done some searching, looks like it hasn't been asked yet but I could be wrong. </p>
<p>Logically</p>
<pre><code>false && false === true
false && true === false
true && false === false
true && true === true
</code></pre>
<p><strong>HOWEVER</strong></p>
<p>It does not seem like this is the case for <code>javascript</code>. I ran the above in the <code>console</code> and this is what I get from FireFox && Chrome:</p>
<pre><code>false && false //console output: false
false && true //console output: false
true && false //console output: false
true && true //console output: true
</code></pre>
<p>I've already found a <a href="https://stackoverflow.com/questions/35941501/java-false-false-work-around">solution</a> but seriously? Why? I would think this to be standard behavior.</p>
<p>It even says in <a href="https://docs.oracle.com/javase/tutorial/java/nutsandbolts/operators.html" rel="nofollow noreferrer"><code>Java</code> documentation</a> that <code>logical AND | &&</code>.</p>

terraform.tfvars vs variables.tf difference : <p>I've been researching this but can't find the distinction. A variables.tf file can store variable defaults/values, like a terraform.tfvars file.</p>
<p>What's the difference between these two and the need for one over the other? My understanding is if you pass in the var file as an argument in terraform via the command line.</p>
<p>There is a thread about this already and the only benefit seems to be passing in the tfvars file as an argument, as you can "potentially" do assignment of variables in a variable.tf file.</p>
<p>Is this the correct thinking?</p>

get position of marker in google maps : I am trying to get the current position that mean longitude and latitude of the marker. First a marker becomes created at the users location and when the user click on the map the previous one becomes deleted and a new one becomes created at the users clickpoint. I tried it by my own with `var lat1 = markers.position.lat(); var lng1 = markers.position.lng();` but that havent work and I get with this the error message `Uncaught TypeError: Cannot read property 'lat' of undefined`. How can I get the current position of the marker and save it in a variable?
var markers = [];
// This event listener will call addMarker() when the map is clicked.
map.addListener('click', function(event) {
addMarkers(event.latLng);
});
//draw a marker at the position of the user
addMarkers(pos);
// Adds a marker to the map and push to the array.
function addMarkers(location) {
var marker = new google.maps.Marker({
position: location,
map: map
});
markers.push(marker);
}
// Sets the map on all markers in the array.
function setMapOnAll(map) {
for (var i = 0; i < markers.length; i++) {
markers[i].setMap(map);
}
}
// Removes the markers from the map, but keeps them in the array.
function clearMarkers() {
setMapOnAll(null);
}
// Deletes all markers in the array by removing references to them.
function deleteMarkers() {
clearMarkers();
marker = [];

What is the (kind of) inverse operation to Java's Stream.flatMap()? : <p>The <code>Stream.flatMap()</code> operation transforms a stream of </p>
<pre><code>a, b, c
</code></pre>
<p>into a stream that contains zero or more elements for each input element, e.g. </p>
<pre><code>a1, a2, c1, c2, c3
</code></pre>
<p>Is there the opposite operations that batches up a few elements into one new one?</p>
<ul>
<li>It is not .reduce(), because this produces only one result</li>
<li>It is not collect(), because this only fills a container (afaiu)</li>
<li>It is not forEach(), because this has returns just <code>void</code> and works with side effects</li>
</ul>
<p>Does it exist? can I simulate it in any way?</p>

Approach here was to convert this string first to list of lists and then make the first list elements as keys and rest other as values to this keys.
if someone can please help me on this?

PHP: Find highest index of numeric array that has missing elements : <p>Say I have the following array:</p>
<pre><code>$n[5] = "hello";
$n[10]= "goodbye";`
</code></pre>
<p>I would like to find out the highest index of this array.
In Javascript, I could do <code>$n.length - 1</code> which would return <code>10</code>.
In PHP, though, <code>count($n)</code> returns 2, which is the number of elements in the array.</p>
<p>So how to get the highest index of the array?</p>

Compare strings doesn't work well : Why my comparation doesn't work well?
I would expect that return would be True, but it wasn't.

Scoped CSS not being applied within the component : <p>I have the following form component:</p>
<pre><code><template>
<div>
<form>
<input placeholder="Recipe Name">
<textarea placeholder="Recipe Description..." rows="10"></textarea>
</form>
</div>
</template>
<script>
export default {
name: 'AddRecipeForm'
}
</script>
<style scoped>
form {
display: flex;
flex-direction: column;
}
</style>
</code></pre>
<p>The <code><style></code> uses the <code>scoped</code> attribute.</p>
<p>When applied, the CSS <strong>does not</strong> get loaded in. When <code>scoped</code> is removed, it <strong><em>does</em></strong> get applied.</p>
<p>However I want to keep it local to the component.</p>
<p>Why is the CSS not getting applied when the <code>scoped</code> attribute is present?</p>

install pip3 for conda : <p>Python2.6 was installed by default in my old centos server. Now I want to create a Python3 environment to install python3 specific module by conda </p>
<pre><code>conda create -n py3 python=3.5.3
source activate py3
</code></pre>
<p>After activate the py3, I try to install hovercraft by <code>pip3 install hovercraft</code>, the shell tells "command not found: pip3". At first I thought pip3 was installed with Python3, but the result was not the case.<br>
So I think I can install it manually. The package gzip file was downloaded from <a href="https://pypi.python.org/packages/18/ce/a39cdc0c467098a1c274b6cd3a62115f831340e45731d64bc7cc08fcdfc6/hovercraft-2.3.tar.gz" rel="noreferrer">python package index</a>, and install by <code>conda install --file hovercraft-2.3.tar.gz</code>. But it doesn't work.<br>
Now I have two problems:</p>
<ol>
<li>how to install pip3 for virtual-env create by conda? </li>
<li>Is it possible to install python package index downloaded package locally in conda?</li>
</ol>

How to configure webpack dev server with react router dom v4? : <p>This is the code of my webpack configuration: </p>
<pre><code>const compiler = webpack({

module: {
loaders: [
{
exclude: /node_modules/,
test: /\.js$/,
loader: 'babel',

},
output: {filename: 'app.js', path: '/'},
});
const app = new WebpackDevServer(compiler, {
contentBase: '/public/',
proxy: {'/graphql': `http://localhost:${GRAPHQL_PORT}`},
publicPath: '/js/',
stats: {colors: true},
});
app.use('/', express.static(path.resolve(__dirname, 'public')));
</code></pre>
<p>Works fine, the app runs on localhost:3000/index.html but when I try to implement React Router dom v4. It doesn't work. This is the code:</p>
<pre><code>const About = () => <div> <h1>About</h1> </div>
ReactDOM.render(
<BrowserRouter>
<div>
<Route exact path='/' component={App}/>
<Route path='/about' component={About}/>
</div>
</BrowserRouter>,
mountNode
);
</code></pre>
<p>This is the result on localhost:3000/ <a href="https://i.stack.imgur.com/SFFGk.png" rel="noreferrer"><img src="https://i.stack.imgur.com/SFFGk.png" alt="build.min.js"></a>
And on localhost:3000/about. I get an error: Cannot GET /about . Not what I'm expecting, why would this not render? <h1>About</h1> </p>

How can I disable source maps in production for a vue.js app? : <p>My app is created with the <code>vue cli</code>. I can't find any option to disable source maps in production.
The <code>npm build</code> step in my <code>package.json</code> looks like this:</p>
<pre><code>"build": "vue-cli-service build",
</code></pre>
<p>In angular, i can just add <code>--prod</code> to my build step to make it work.
Is there any such option for <code>vue.js</code>? Or do I have to change the <code>webpack</code> config (which is hidden by the cli)?</p>

How to notify an object that an event of another object? Java : <p>I have a Java class, named Main, which instances several classes with name Subscriber. Subscriber obtains data from the internet and when it obtains a new data it stores it in a variable. When a new data is saved I want it to notify Main, or that it detects it. How could I do it?</p>
<p>I have thought about using the Observer pattern but in my case I have an observer and many observed</p>

TensorFlow: how is dataset.train.next_batch defined? : <p>I am trying to learn TensorFlow and studying the example at: <a href="https://github.com/aymericdamien/TensorFlow-Examples/blob/master/notebooks/3_NeuralNetworks/autoencoder.ipynb" rel="noreferrer">https://github.com/aymericdamien/TensorFlow-Examples/blob/master/notebooks/3_NeuralNetworks/autoencoder.ipynb</a></p>
<p>I then have some questions in the code below:</p>
<pre><code>for epoch in range(training_epochs):
# Loop over all batches
for i in range(total_batch):
batch_xs, batch_ys = mnist.train.next_batch(batch_size)
# Run optimization op (backprop) and cost op (to get loss value)
_, c = sess.run([optimizer, cost], feed_dict={X: batch_xs})
# Display logs per epoch step
if epoch % display_step == 0:
print("Epoch:", '%04d' % (epoch+1),
"cost=", "{:.9f}".format(c))
</code></pre>
<p>Since mnist is just a dataset, what exactly does <code>mnist.train.next_batch</code> mean? How was the <code>dataset.train.next_batch</code> defined?</p>
<p>Thanks!</p>

How to put something on the screen? : <p>I use <strong>Ubuntu Studio 15.10</strong> and I want to learn to program in <strong>C++</strong>.</p>
<p>I'm absolutely new into the <strong>C++</strong> programming world.</p>
<p>I wrote my first "code", with <strong>gedit</strong>.</p>
<p>In simple words, I want to put on the screen some text (like the old Basic: PRINT "Hello!").</p>
<p>So, I wrote:</p>
<pre><code>#include <iostream>
using namespace std;
#include <cmath>
#include <cstdlib>
const double PI = atan(1) * 4;
int main()
{
cout << "Hello" << std::endl;
cout << "This is my first code with C++." << std::endl;
cout << "Let's see what happen." << std::endl;
cout << "2 * 3 = "; cout << 2 * 3 << std::endl;
cout << "Constante pi = "; cout << PI << std::endl;
cout << "Seno de 45º = "; cout << sin((45*PI)/180) << std::endl;
cout << "Coseno de 30º = "; cout << cos((30*PI)/180) << std::endl;
cout << "Tangente de 45º = "; cout << tan((45*PI)/180) << std::endl;
return 0;
}
</code></pre>
<p>Then, I used <strong>Codelite</strong> to compile it and... I get a lot of files and folders.</p>
<p>The supposed executable file is called <strong>main.cc</strong>.</p>
<p>BUT... When I ask the system to run that file... Nothing happen!!!</p>
<p>I mean, there is not any text into any screen pane, any new window... Nothing, just Nothing!!!</p>
<p>What's wrong, here?</p>
<p>How can I get to see what I want to see into the screen?</p>

How to use IPFS from Javascript app without running ipfs node? : <p>I have javascript app (ReactJs) which will run as an android hybrid app on mobile devices. I do not want to run full IPFS node on a mobile device, because it will consume a lot of its memory and energy. How can I connect my app to IPFS then?</p>
<p>I saw <a href="https://github.com/ipfs/js-ipfs-api#importing-the-module-and-usage" rel="noreferrer">https://github.com/ipfs/js-ipfs-api#importing-the-module-and-usage</a>, but it does not look usable for a mobile device again as it runs as a separated service.</p>
<p>Probably I have to connect to some IPFS node at the internet through IPFS API (<a href="https://ipfs.io/docs/api/" rel="noreferrer">https://ipfs.io/docs/api/</a>), however is there a way to discover running nodes on the runtime and also to choose the fastest/closest one?</p>

PHP script wont perform query : So I'm having a bit of trouble on this. I'm not sure if this information is important but this script was working at one point, but it kept making multiple records for every submission (It seemed like it was making a submission for every inputted form value)
eg. if first name and last name were entered, 2 records would be created.
Besides that though, this is the code I'm having trouble with right now:
**(connection.php)**
<?php
$host = "localhost";
$dbusername = "root";
$dbpassword = "";
$dbname = "contacts";
$conn = new mysqli($host, $dbusername, $dbpassword, $dbname);
if($conn)
{
echo "Connection OK!";
}
else
{
die("Connection failed");
}
?>
**(index.html)**
<?php
include ("connection.php");
$fn = isset ($_GET['first_name'])? $_GET['first_name'] : null;
$ln = isset ($_GET['last_name'])? $_GET['last_name'] : null;
$query = "INSERT INTO contact VALUES ('fn','ln')";
$data = mysqli_query($conn, $query);
if($data)
{
echo "Data inserted!";
}
?>
the connection seems to be working just fine because i'm getting a "Connection OK" message, and the variables also seem to change based on the form values... but the query will not work no matter what I do now (I'm trying to fill a table with the above values if that isn't obvious)... I'm using Apollo 2.435 in case there is a plugin issue and you know how I could fix that (That also seems to be working seeing as all of the above code is working within an HTML document)
Thanks for your help.

Tensorflow Different ways to Export and Run graph in C++ : <p>For importing your trained network to the C++ you need to export your network to be able to do so. After searching a lot and finding almost no information about it, it was clarified that we should use <a href="https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/tools/freeze_graph.py" rel="noreferrer">freeze_graph()</a> to be able to do it.</p>
<p>Thanks to the new 0.7 version of Tensorflow, they added <a href="https://www.tensorflow.org/versions/r0.7/api_docs/python/train.html#export_meta_graph" rel="noreferrer">documentation</a> of it. </p>
<p>After looking into documentations, I found that there are few similar methods, can you tell what is the difference between <code>freeze_graph()</code> and:
<code>tf.train.export_meta_graph</code> as it has similar parameters, but it seems it can also be used for importing models to C++ (I just guess the difference is that for using the file output by this method you can only use <code>import_graph_def()</code> or it's something else?)</p>
<p>Also one question about how to use <code>write_graph()</code>:
In documentations the <code>graph_def</code> is given by <code>sess.graph_def</code> but in examples in <code>freeze_graph()</code> it is <code>sess.graph.as_graph_def()</code>. What is the difference between these two? </p>
<p>This question is related to <a href="https://github.com/tensorflow/tensorflow/issues/615" rel="noreferrer">this issue.</a></p>
<p>Thank you!</p>

Java getInstance() with a Generic class using Singleton pattern : I'm new to Generics and the Singleton pattern in Java. I have the following questions:
-Is a Generic class compatible with the Singleton Pattern, namely having a static instance?
-If so, I have the following Generic class that I want to convert to a Singleton. What is the best practice?
-(Noob question) Is there a good way to de-generify an instance of the class in runtime? passing the class as parameter in getInstance()?
class GenFooSingleton <T>
{
private T t;
// Prevent direct instantiation
private GenFooSingleton(T o){
this.t = o;
}
private static GenFooSingleton INSTANCE = null;
// Returns the single instance of this class, creating it if necessary
static synchronized <T> GenFooSingleton<T> getInstance(T tClass)
{
if (INSTANCE == null)
{
INSTANCE = new GenFooSingleton<>(tClass);
}
return INSTANCE;
}
}
Thank you so much for your time.

What is a concise way to create a 2D slice in Go? : <p>I am learning Go by going through <a href="https://tour.golang.org/list" rel="noreferrer">A Tour of Go</a>. One of the exercises there asks me to create a 2D slice of <code>dy</code> rows and <code>dx</code> columns containing <code>uint8</code>. My current approach, which works, is this: </p>
<pre><code>a:= make([][]uint8, dy) // initialize a slice of dy slices
for i:=0;i<dy;i++ {
a[i] = make([]uint8, dx) // initialize a slice of dx unit8 in each of dy slices
}
</code></pre>
<p>I think that iterating through each slice to initialize it is too verbose. And if the slice had more dimensions, the code would become unwieldy. Is there a concise way to initialize 2D (or n-dimensional) slices in Go? </p>

what is the difference between import and const and which is preferred in commonjs : <p>I have noticed a bit of switching between using const and import for referencing libraries in node.js applications using es6 syntax with Babel.</p>
<p>What is the preferred method and what is the difference between using const and import? Assuming you may be importing the same library in many files/components.</p>
<p><strong>const</strong></p>
<pre><code>const React = require('react')
</code></pre>
<p><strong>import</strong></p>
<pre><code>import React from 'react'
</code></pre>
<p>Here are the definitions of each but I am still not sure which to use.</p>
<p><a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import">import</a></p>
<p>The import statement is used to import functions, objects or primitives that have been exported from an external module, another script, etc.</p>
<p><a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/const">const</a></p>
<p>The const declaration creates a read-only reference to a value. It does not mean the value it holds is immutable, just that the variable identifier cannot be reassigned.</p>

Using `instanceof` on objects created with constructors from deep npm dependencies : <h2>Background:</h2>
<p>I have an npm module that I have common error handling code in, including a custom error:</p>
<pre><code>function CustomError () { /* ... */ }
CustomError.prototype = Object.create(Error.prototype);
CustomError.prototype.constructor = CustomError;
module.exports = CustomError;
</code></pre>
<p>I have some other modules (let's call them <strong>'module-a'</strong> and <strong>'module-b'</strong>) which both depend on the error handling module.</p>
<p>I also have some code with uses Bluebirds "filtered catch" functionality:</p>
<pre><code>doSomething
.catch(CustomError, () => { /* ... */ });
</code></pre>
<h2>The issue:</h2>
<p>After some debugging I've discovered (somewhat obviously in hindsight) that errors created in <strong>'module-a'</strong> are not instances of errors created by <strong>'module-b'</strong>. This is because both modules have their own copy of the JS file containing the <code>CustomError</code> constructor, which are both run independently.</p>
<p>I would rather not have to resort to my current solution, which is basically:</p>
<pre><code>CustomError.isCustomError = e => e.constructor.toString() === CustomError.toString();
</code></pre>
<p>and then:</p>
<pre><code>doSomething
.then(CustomError.isCustomError, () => { /* ... */ });
</code></pre>
<p>This is clearly flimsy, and will fall apart if the versions fall out of sync.</p>
<h2>So...</h2>
<p>Is there some way to ensure that <strong>'module-a'</strong> and <strong>'module-b'</strong> both use the same instance of the constructor? Or another, less fragile solution.</p>

HttpClient keeps receiving bad request : <p>I'm having a hard time resolving my Bad Request responses from a REST api when I'm creating a client using C#. I tested the REST api using Fiddler 2 and executing it there, but when I'm creating the same thing programmatically I get 400 response. Here is my Fiddler composer test:</p>
<p>URL:</p>

<p>Here are my Headers</p>
<pre><code>User-Agent: Fiddler
Content-Type: application/json
Accept: application/json
icSessionId: PomCSBCVU4VgXCJ5

<pre><code>{
"@type": "job",
"taskId":"0000G20G000000000002",
"taskName":"TestReplication",
"taskType":"DRS",
"callbackURL":""
}
</code></pre>
<p>This POST comes back with a 200 response and a response body, which is perfect, but when I try to simulate the same thing in C# with this code:</p>
<pre><code>public JobResponse RunJob(JobRequest jobRequest)
{
try
{
client = new HttpClient();
client.BaseAddress = new Uri(loggedUser.serverUrl + "/");
client.DefaultRequestHeaders.Clear();
client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.TryAddWithoutValidation("icSessionId", icSessionId);
string message = JsonConvert.SerializeObject(jobRequest);
message = message.Insert(1, "\"@type\": \"job\",");
Console.WriteLine(message);
var response = client.PostAsJsonAsync("api/v2/job", message).Result;
if (response.IsSuccessStatusCode)
{
return response.Content.ReadAsAsync<JobResponse>().Result;
}

{
var result = response.Content.ReadAsStringAsync().Result;
Console.WriteLine(result);
}
}
catch (Exception ex)

Telegram working with editable data : I was wondering which way is the best to implement the following in telegram bot:
some catalog that containts some type of items with descriptions. For example,
Types - phones, cars, laptops.
Items - in phones: iphone, samsung, LG
In cars: BMW, Nissan
In laptops: lenovo, MSI, Dell.
Each of them has a description. I want a user to navigate through buttons, I already know how to add buttons with pre-written categories, but I want it to make editable not only through IDE but only through some commands in my bot.
Overall my bot will perform the following:
a user enters and writes /start
here he receives three buttons - phones, cars, laptops
then, let's imagine, he clicks phones. Now he has iphone, samsung, LG and back button. Then he clicks iphone and now he gets an image with a description. Then clicks samsung and gets another image w/ description, etc.
I want all this to be saveable and readable from a file or database so that it was easy for another people to edit in future. Which way should I go? Should I implement some graph? Or just an input.txt files with categories and names? Or should I go harder w/ MySQL database? And how to implement it? Thanks in advance!

Disable animation on notifyItemRangeInserted() : <p>I'm using a RecyclerView. After adding items to the RecyclerView, I need to call:</p>
<pre><code>notifyItemRangeInserted(int positionStart, int itemCount);
</code></pre>
<p>However, this shows a sort of "slide down" animation. Is there a way that I can disable this animation?</p>

System architecture : design considerations. Java vs Django vs RoR : <p>I'd like to designing new web application with few requirements and considering which language/framework I should choose.</p>
<p>Requirements: </p>
<ul>
<li>Web based solution (web UI and backed)</li>
<li><p>Fast deployment and setup <- by this I mean just run by single command,
no configuration needed for total beginner. Similar to
Jenkins</p>
<p>java -jar jenkins.war</p>
<p>or Gerrit.</p></li>
<li>Some kind of que to run tasks asynchronously.</li>
<li>No code protection</li>
</ul>
<p>Due to the fact that I want to be simple to run and deploy (without initial configuration needed) I am considering using <strong>Java EE/Spring</strong> framework.
Initially I was considering <strong>Django or RoR</strong> since deploy is pretty easy and development is way faster than Java but those
frameworks need some kind of scheduling framework like <strong>Celery + some kind of broker</strong> so additional configuration is needed.
I am not limited to any language,(besides PHP since I just do not like it :P)</p>
<p>If any of you have any thoughts about my design and want to share let's do it.</p>
<p>Thanks a lot for any kind of question/ answers.</p>

Is there a way to tell flow to typecheck every file, not just the ones with /* flow */? : <p>In the official examples they always have <code>/* @flow */</code> at the top of the page. Now that's nice and helpful for an existing project, where I want to opt-in to flow for each file. Building a new project from scratch I would like to just have flow type checking everywhere, without having to type <code>/* @flow */</code> every time. Is it possible?</p>

<p>This works fine. </p>

How can I encrypt data so that a web application can read it, but someone with access to the web server cannot? : <p>I am building a system to store survey data where one of the requirements is that if a hacker gets access to the web server, they are not able to view any of the data. But, the web application does need to be able to decrypt the data and display it (for instance an authenticated user might need to see a table containing survey responses in plain text).</p>
<p>I am having trouble figuring out how the web server could decrypt data without a hacker also being able to do it. Obviously if the decryption key is stored on the server access to the server also entails access to the decryption key.</p>
<p>The only thing I can think of so far is to distribute a decryption key to the users, have them enter it as part of the authentication process, store it in a cookie, and then submit the key with every web request so that it's never stored on the server and instead only in memory for limited periods of time. Obviously this would be served over HTTPS so that the key is also encrypted at transmission time. </p>
<p>I have never seen a system that requires a private key as part of the authentication process, so I'm assuming there is a much better way to do this. </p>
<p>While this is more of a theoretical question, the application will be written in PHP, likely using the Laravel framework, hosted on an Ubuntu server. </p>

Python: Printing a set amount of characters : I have a query about python. This is for a project at school, and I'm quite new to coding in python.
Basically, I am making a program that prints a set amount of 'X's and spaces, like x x x x x...
However, I want the user to choose how many 'X's and spaces they want to print.
This is all I've done so far:
```xnum = input("Choose the amount of 'X's you would like to be printed")
xnum = xnum.upper()
spacenum = input("Choose the amount of spaces you would like to be printed")
linenum = input("Choose how many characters you would like to be displayed on one line")```
I want to find out how to make the program print the number of 'X's the user asks for, and same with the spaces.
Thank you very much!
PS: I already have the code for how many characters per line, I just need some help on printing the set amount of 'X's and spaces.

How should I customize DropdownButtons and DropdownMenuItems in Flutter? : <p>The default <a href="https://docs.flutter.io/flutter/material/DropdownButton-class.html" rel="noreferrer">DropdownButton</a> with DropdownMenuItems returns a light-grey dropdown. How should I customize the dropdown (e.g. background color, dropdown width)? I can change the <code>style</code> property in both DropdownButton and DropdownMenuItem, like this:</p>
<pre><code>return new DropdownButton(
value: ...,
items: ...,
onChanged: ...,
style: new TextStyle(
color: Colors.white,
),
);
</code></pre>
<p>but this doesn't change the dropdown's background color.</p>
<p>Should I copy DropdownMenu and extend it? Does Flutter plan to add customization for this widget in the near future?</p>

What affects the time for a function to return to the caller. : <p>I measure the run time of two algorithms. </p>
<p>my main() function calls two algorithms and measures the time respectively. </p>
<p>Assume A() and B() are the names for the algorithms. </p>
<p>what I did was like (please ignore details here)</p>
<pre><code>begin =
A();
end =
cout << "time A : " << end-begin << endl;
begin =
B();
end =
cout << "time B : " << end-begin << endl;
</code></pre>
<p>and I also measure the time inside of each function.
for example, </p>
<pre><code>A()
{
begin =
.....
end =
cout << "time inside A : " << end - begin << endl;
return ..;
}
B()
{
begin =
.....
end =
cout << "time inside B : " << end - begin << endl;
return ..;
}
</code></pre>
<p>It seems the time measuring in main() function and inside of A() function has very little difference. (like 150 milliseconds)
but for the B(), it has more than 1500 milliseconds difference. </p>
<p>So, I would like to know what can affect this big difference between two functions call.</p>

I want to identify the public ip of the terraform execution environment and add it to the security group : <p>I want to identify the public IP of the terraform execution environment
and add it to aws security group inbound to prevent access from other environments.</p>
<p>Currently, I am manually editing the values in the variables.tf file.</p>
<p>variables.tf</p>
<pre><code>variable public_ip_address {
default = "xx"
}
</code></pre>
<p>I would like to execute the "curl ifconfig.co" command on the local host and automatically set the security group based on the result</p>
<p>Is there a way to do such things?</p>
<p>I could do it by putting the result of local-exec in some variable
but I don't know how to do it.</p>
<p>Thank you for reading my question.</p>
