How to create customize plot (Figure) in MATLAB? : <p>I want to create plots based on similar values as attached below.</p>
<p><a href="https://i.stack.imgur.com/Y2bQw.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Y2bQw.jpg" alt="Table"></a></p>
<p>The figure should look like as shown below. Here, whenever the weight is 1, the index value should be in color, or bold fonts. </p>
<p>Though I am good in plotting graphs in MATLAB, this seems quite tricky.</p>
<p>How to do this, a little hint will serve the purpose.</p>

AWS EC2, command line display instance type : <p>Do you guys know if we can display the EC2 instance type using command line?</p>
<p>Currently, I only have access to the command line of an EC2 instance. Is there a command line that I can type to display the type of instance. eg, <code>p2.8xLarge</code> or <code>g.16x</code> etc. </p>

How to make Xcode automatically conform to a protocol : <p>When I use a prototype table view, I always have to conform to the protocol <code>TableViewDataSource</code>. I always forget what methods I need to implement, so I have to look at the source of the protocol every time. This is really time consuming.</p>
<p>I think Xcode must have a feature that automatically implements the needed methods for you, right? Just like IntelliJ IDEA, Eclipse, and Visual Studio.</p>
<p>I want to know where can I find this feature. If there's isn't, is there a workaround for this? At least I don't have to open the source code of the protocol each time I conform to it.</p>
<p>If you don't understand what I mean, here's some code:</p>
<p>I have a protocol</p>
<pre><code>protocol Hello {
func doStuff ()
}
</code></pre>
<p>When I conform to it,</p>
<pre><code>class MyClass: Hello {
}
</code></pre>
<p>I often don't remember the names of the methods that I need to implement. If Xcode has a feature that turns the above code, into this:</p>
<pre><code>class MyClass: Hello {
func doStuff () {
code
}
}
</code></pre>
<p>Now you understand what I mean? I just want to ask where to find such a feature.</p>

how to convert a list into a 2d matrix in python? : i have my data in form of list but for easy access i need them to be in matrix of 11rows known as p0-p10 and 4 columns as a,b,c,d.
this is my data
[[0.078125, 0.328125, 0.328125, 0.265625], [0.171875, 0.390625, 0.140625, 0.296875], [0.109375, 0.015625, 0.015625, 0.859375], [0.859375, 0.015625, 0.109375, 0.015625], [0.953125, 0.015625, 0.015625, 0.015625], [0.015625, 0.015625, 0.234375, 0.734375], [0.046875, 0.921875, 0.015625, 0.015625], [0.109375, 0.421875, 0.109375, 0.359375], [0.140625, 0.484375, 0.359375, 0.015625], [0.078125, 0.296875, 0.421875, 0.203125]]

Custom mailchimp signup form in React : <p>I have a react app that I would like to add mailchimp signup form to. I am building a custom signup form and have user sign up by entering their first and last name and email. I am not dealing with any campaign stuff. All I am trying to achieve is that once they sign up, they get an email to confirm subscription.</p>
<p>I have done what's in the mailchimp guide <a href="http://kb.mailchimp.com/lists/signup-forms/host-your-own-signup-forms" rel="noreferrer">http://kb.mailchimp.com/lists/signup-forms/host-your-own-signup-forms</a> but it's always giving me error 500.</p>
<p>Here's the code for the send event</p>
<pre><code>subscribe(event) {
event.preventDefault();
axios({
url: 'https://xxxxxx.us15.list-manage.com/subscribe/post',
method: 'post',
data: this.state,
dataType: 'json'
})
.then(() => {
console.log('success');
});
}
</code></pre>
<p>and here's the form</p>
<pre><code><form onSubmit={this.subscribe.bind(this)}>
<input type="hidden" name="u" value="xxxxxxxxxxx" />
<input type="hidden" name="id" value="xxxxxxxxxxx" />
<label>First Name</label>
<input name="FNAME" type="text" onChange={this.handler.bind(this, 'FNAME')} required="true"/>
<label>Last Name</label>
<input name="LNAME" type="text" onChange={this.handler.bind(this, 'LNAME')} required="true"/>
<label>Email</label>
<input name="EMAIL" type="email" onChange={this.handler.bind(this, 'EMAIL')} required="true"/>
<button type="submit" name="submit">Subscribe</button>
</form>
</code></pre>
<p>I have also tried the suggestion in this link <a href="https://stackoverflow.com/questions/8425701/ajax-mailchimp-signup-form-integration">AJAX Mailchimp signup form integration</a></p>
<p>basically passing the u and id along with the url instead of input in the form. but that didn't work either.</p>
<p>Anyone has idea on how to make this work? Thanks!!</p>

What's the correct way to implement login page in Xamarin Shell? : <p>My app has structure like this.</p>
<p>Splash page => Login page => Main page</p>
<p>After login, user cannot go back to login/splash page. There are several pages in flyout menu that user can go to. However, login/splash items should not be showed in these flyout menu items.</p>
<p>Some project may try to load main page first before show login page as a modal page. I think this way doesn't work because it should take so much time to load complex main page before send user back to login.</p>

Homebrew PHP appears not to be linked. - Valet : <p>I had a problem which appeared all of the sudden saying:
<code>Unable to determine linked PHP.</code> which I could not solve so I uninstalled valet, php and dependencies. Then I installed fresh <code>php7.1</code> but when I run <code>valet install</code> I get quiet slightly similar error: <code>Homebrew PHP appears not to be linked.</code></p>

Regular expression : I have this context free grammar :
S -> aSb
S -> aSa
S -> bSa
S -> bSb
S -> epsilon
I want to show that this grammar describes a regular language ( namely can be represented as a regular expression) but I'm not sure how to do that and get the confident I'm not missing any pattern.
I did not see this exact question and that why I don't think it is duplicate. I'd like an explanation on this relative simple example. It was hard for me to follow more complicated examples.

Send attachment from Android Device to another automatically - Android studio : I have Android Studio code that creates a new wav file every 30 seconds, I need to send these wav files to another device ( As some sort of notification) as they are made.
I can't use the traditional andorid studio default/built-in app for this as I need to send the email automatically without user input. I found a way to send the email automatically in background, from the source below, but I cannot get it to send the wav file attachment:
http://www.wisdomitsol.com/blog/android/sending-email-in-android-without-using-the-default-built-in-application
Any advice about the best way to achieve this would be greatly appreciated.

Minecraft 1.12.2 ping von Spieler Ermitteln : ich wollte von einem Spieler die Ping ermitteln. In der Version 1.8.8 hat auch alles super Funktioniert, aber wenn ich den Code auf der 1.12.2 anwende, kommen da unlogische ergebnisse raus. Ich bekomme auf meinem localhost eine Ping von 200 oder so zurück, obwohl ich auf dem 1.8er server einen 0er ping habe. Ist ja auch klar, weil Localhost...
Ich habe es auf meinem Root server und auf meinem Localhost getestet. Ich habe gegoogled aber immer nur tutorials für die 1.8 gefunden
```Java

Eslint determine globals from another file : <p>I'm trying to set up ESLint in such a way that it parses a globals declaration file before linting the actual target file, so that I don't have to declare as globals all the functions and variables that are indeed globals, but letting the parser figure that out:</p>
<p>In <strong>some_module.js</strong>:</p>
<pre><code>function do_something() {
if (glob_action("foobar")) {
... something something ...
}
}
</code></pre>
<p>While in <strong>globals.js</strong> I have a set of utilities and global variables:</p>
<pre><code>function glob_action(x) {
... something something ...
}
</code></pre>
<p>So how can I tell to ESlint to include global.js in determining the fact that:</p>
<pre><code>76:3 error 'glob_action' is not defined no-undef
</code></pre>
<p>is not actually undefined, but I do NOT want to list it as global:</p>
<pre><code>/*global glob_action*/
</code></pre>
<p>I would like to do something like:</p>
<pre><code>/*eslint include "../globa.js"*/
</code></pre>
<p>Is it possible? How?</p>

Deleting multiple items based on global secondary index in DynamoDB : <p>I have an existing table which has two fields - primary key and a global secondary index:</p>
<pre><code>----------------------------
primary key | attributeA(GSI)
----------------------------
1 | id1
2 | id1
3 | id2
4 | id2
5 | id1
</code></pre>
<p>Since having the attributeA as a global secondary index, can I delete all items by specifying a value for the global secondary index? i.e I want to delete all records with the attributeA being id1 - Is this possible in Dynamo? </p>
<p>Dynamo provides documentation about deleting the index itself, but not specifically if we can use the GSI to delete multiple items </p>

Comparing only dates of DateTimes in Dart : <p>I need to store and compare dates (without times) in my app, without caring about time zones.<br>
I can see three solutions to this:</p>
<ol>
<li><p><code>(date1.year == date2.year && date1.month == date2.month && date1.day == date2.day)</code><br>
This is what I'm doing now, but it's horrible verbose.</p></li>
<li><p><code>date1.format("YYYYMMDD") == date2.format("YYYYMMDD")</code><br>
This is still rather verbose (though not as bad), but just seems inefficient to me...</p></li>
<li><p>Create a new Date class myself, perhaps storing the date as a "YYYYMMDD" string, or number of days since Jan 1 1980. But this means re-implementing a whole bunch of complex logic like different month lengths, adding/subtracting and leap years.</p></li>
</ol>
<p>Creating a new class also avoids an edge case I'm worried about, where adding <code>Duration(days: 1)</code> ends up with the same date due to daylight saving changes. But there are probably edge cases with this method I'm not thinking of...</p>
<p>Which is the best of these solutions, or is there an even better solution I haven't thought of?</p>

A Framework to remind the user that their login is about to expire : <p>Is there a framework that I can implement on a MVC website which will hook into my session and provide a reminder that their login is about to time out? </p>
<p>Ideally I would like to provide a view which would have the popup message on which can be configured.</p>
<p>Also how would it work across browser tabs? If there were two tabs and you logged out on one then the session would be finished on the second tab. Is there a way of gracefully redirecting the second tab to the login page. For example if on second tab and fire some AJAX to a secured action I then get a fail. Could that redirect to login?</p>
<p>I written something like this in the past but can be time consuming to test etc. and the multi tab issue was tricky.</p>
<p>Ideally I am wanting something to plug in and use and configure.</p>

Does a postgres foreign key imply an index? : <p>I have a postgres table (lets call this table <code>Events</code>) with a composite foreign key to another table (lets call this table <code>Logs</code>). The Events table looks like this:</p>
<pre><code>CREATE TABLE Events (
ColPrimary UUID,
ColA VARCHAR(50),
ColB VARCHAR(50),
ColC VARCHAR(50),
PRIMARY KEY (ColPrimary),
FOREIGN KEY (ColA, ColB, ColC) REFERENCES Logs(ColA, ColB, ColC)
);
</code></pre>
<p>In this case, I know that I can efficiently search for Events by the primary key, and join to Logs.</p>
<p>What I am interested in is if this foreign key creates an index on the Events table which can be useful even without joining. For example, would the following query benefit from the FK?</p>
<pre><code>SELECT * FROM Events
WHERE ColA='foo' AND ColB='bar'
</code></pre>
<p>Note: I have run the POSTGRES EXPLAIN for a very similar case to this, and see that the query will result in a full table scan. I am not sure if this is because the FK is not helpful for this query, or if my data size is small and a scan is more efficient at my current scale.</p>

glVertexAttribPointer and glVertexAttribFormat: What's the difference? : <p>OpenGL 4.3 and OpenGL ES 3.1 added several alternative functions for specifying vertex arrays: <code>glVertexAttribFormat</code>, <code>glBindVertexBuffers</code>, etc. But we already had functions for specifying vertex arrays. Namely <code>glVertexAttribPointer</code>.</p>

Why are packages installed rather than just linked to a specific environment? : <p>I've noticed that normally when packages are installed using various package managers (for python), they are installed in <code>/home/user/anaconda3/envs/env_name/</code> on conda and in <code>/home/user/anaconda3/envs/env_name/lib/python3.6/lib-packages/</code> using pip on conda. </p>
<p>But conda caches all the recently downloaded packages too.</p>
<p>So, my question is:
Why doesn't conda install all the packages on a central location and then when installed in a specific environment create a link to the directory rather than installing it there?</p>
<p>I've noticed that environments grow quite big and that this method would probably be able to save a bit of space.</p>

Correct way to retrieve token for FCM - iOS 10 Swift 3 : <p>i had implement Firebase with FirebaseAuth/FCM etc and did sent notification successfully through Firebase Console. </p>
<p>However i would need to push the notification from my own app server.</p>
<p>i am wondering below which way is correct way to retrieve the registration id for the device:-</p>
<p><strong>1) retrieve registration id token from didRegisterForRemoteNotificationWithDeviceToken</strong></p>
<pre><code>func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
var token = ""
for i in 0..<deviceToken.count {
token += String(format: "%02.2hhx", arguments: [deviceToken[i]])
}
print("Registration succeeded!")
print("Token: ", token)
Callquery(token)
}
</code></pre>
<p><strong>2) Retrieve Registration token from firebase</strong> (Based on Firebase document which retrieve the current registration token)</p>
<pre><code>let token = FIRInstanceID.instanceID().token()!
</code></pre>
<p>i was using the first way, the push notification is not being received even the registration id is stored on my app server database accordingly and i get this CURL session result :-</p>
<pre><code>{"multicast_id":6074293608087656831,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}
</code></pre>
<p>i had also tried the second way and get fatal error while running the app as below:-
<a href="https://i.stack.imgur.com/ZeQ9U.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ZeQ9U.png" alt="enter image description here"></a></p>
<p>appreciated if anyone could point me the right way, thanks!</p>

Okay so I'm coding a roll the die game on java : This is the code I have, but I want it to be able roll the die based on the number of trials the user inputs and then display the frequencies of each face. This code isn't working at I would want it to. Also I would like to change the switch cases to if and else if statements, if anybody could help me out with that would be amazing, I've been working on this for a while now.
import java.util.Random;

public class DieRoll {
public static void main(String[] args) {
// TODO Auto-generated method stub
Random randomNumbers = new Random();
int one=0;
int two=0;
int three=0;
int four=0;
int five=0;
int six=0;
int trials;
int face;
System.out.println("Please enter the number of trials");
Scanner scan= new Scanner (System.in);
trials= scan.nextInt();
for(int rolls= 1; rolls==trials; rolls++);{
face= randomNumbers.nextInt(6) + 1;
// determine roll value 1-6 and increment appropriate counter
switch ( face )
{
case 1:
++one; // increment the 1s counter
break;
case 2:
++two; // increment the 2s counter
break;
case 3:
++three; // increment the 3s counter

case 4:

break;
case 5:

break;
case 6:
++six; // increment the 6s counter
break; // optional at end of switch
}
}
System.out.println( "Face\tFrequency" ); // output headers

Run parts of bash script : <p>So I want to have an automated Bash script that checks for java and if its not there or super old version (lower than 7) it installs it.</p>
<p>I have something that works, but it runs all part of the bash script yielding odd results.</p>
<p>Code:</p>
<pre><code>#!/bin/bash
# This file will call versions and install if necessary
version_call_java = $(java -version)
java_call_len = ${#version_call_java}
if [[ $version_call_java == *"not found"* ]]; then
echo "It's not there!"
sudo apt-get install java
echo "Installing Java"
elif [[ $version_call_java == *"version*" ]]
echo "Its there!"

<p><a href="https://i.stack.imgur.com/B6olV.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/B6olV.png" alt="Results"></a></p>
<p>Lines 5, 6, and 13 shouldn't run.</p>
<p>Also is my logic correct? I look for the words "not found" for if the machine doesn't have java. Maybe "recognized" is better but not sure if there is a boolean for if a software program exists or not on a machine.</p>

Having trouble getting my PDO query to display on another page : <p>I have been working on learning PDO. Basically what I am trying to do is display names that are off work on any given day of the year. </p>
<p>I created a prepared statement that gives me the names, based on a date set in a variable. It's working as expected.</p>
<p>The problem I am having is displaying that on a seperate page. Lets say my page with the PDO statement is called vacationnames.php</p>
<p>Depending on the date I need to display those names on 1 of 4 different pages called calendar1.php or calendar2.php...etc.</p>
<p>Here is the code I have:
vacationnames.php</p>
<pre><code>$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
$opt = [
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
PDO::ATTR_EMULATE_PREPARES => false,
];
$db = new PDO($dsn, $user, $pass, $opt);
$sth = $db->prepare("
SELECT (employee.name)Name
, vacation_picks._date1 as Date
FROM employee
LEFT OUTER JOIN
vacation_picks on
employee.employee_id = vacation_picks.employee_id
WHERE vacation_picks._date1 = :day
");
</code></pre>
<p>This is on one of the calendar.php pages
</p>
<pre><code>$myVariable = ('2017-1-1');
// This executes the SQL query, binding the parameter as we go.
$sth->execute(array(
':day' => $myVariable
));
// echo $myVariable;
foreach($sth as $row) {
echo $row['Name'];
}
</code></pre>
<p>Even putting the 'Day One' php on calendar.php with vacationnames.php required_once gives me no result. I would prefer to have it referenced with even less code on calendar.php if possible.</p>
<p>Thanks for looking.</p>
