Interfaces may not include member variables error : <p>I made an Interface for my project which is called <code>insert</code> and goes like this:</p>
<pre><code><?php
interface Insert
{
private $_db;
public function __construct()
{
$this->_db = new Connection();
$this->_db = $this->_db->dbConnect();
}
public function insert($table_name, $data)
{
$string = "INSERT INTO ".$table_name." (";
$string .= implode(",", array_keys($data)) . ') VALUES (';
$string .= "'" . implode("','", array_values($data)) . "')";
if(mysqli_query($this->_db, $string))
{
return true;
}
else
{
echo mysqli_error($this->con);
}
}
}
?>
</code></pre>
<p>But it given me this error:</p>
<p><strong>Fatal error: Interfaces may not include member variables</strong></p>
<p>So what is my mistake here?</p>

Max size of the vector : I'm trying to read in numbers from a file and take the average of all the numbers but i'm unsure how to include the data.reserve() part into my code. How exactly do I use it to set the maximum size of the vector?
// 1) Read in the size of the data to be read (use type size_t)
// 2) Use data.reserve() to set the maximum size of the vector
// 3) Use a for loop to read in the specified number of values,
// storing them into the vector using data.push_back()
void reserve(vector<int> &data) {
cout << "Using reserve!" << endl;
if (cin){
size_t max_size;
//max_size = 12;
data.reserve(max_size);
cout << "max_size = " << max_size << endl;
for (size_t i = 0; i < max_size; i++){
cin >> data[i];
data.push_back(data[i]);
cout << data[i] << " ";
}

About class and object relationship : <p>Can I say that class is a manual for building up an object?</p>
<p>I agreed that object is one of the instance of class.But if some properties that defined by classes may not make sense for particular object, for example,I have an object called "Duck" which use the class "Bird" for build, but Duck cannot fly,so if I use class "Bird" for build up an object "Duck".In the other words, the manual cannot provided the guideline for build up the object.</p>
<p>So,can i say that class is a manual for building up an object?As well as the manual should provided all the functions that the users need,in case there shouldn 't have any defects inside. </p>

How to embed YouTube videos without cookies? : <p>In the past we could embed YouTube videos without cookies by simply pointing to a different URL, so for example <a href="https://youtube-nocookie.com/embed/sRrqF8eXs38" rel="noreferrer">https://youtube-nocookie.com/embed/sRrqF8eXs38</a> to get the version without cookies.</p>
<p>This does not work any longer. The URL returns a <em>404</em>, where the cookie version still exists.</p>
<p>I could not find any reference on how to do it now.</p>

jQuery if Statement with Multiple conditions : I need to check 3 conditions, sheet_exists = 1, recalc = 1 and qty_total and new_qty_total are not equal.
The if statement works well if only the first 2 arguments are used:
if(sheet_exists === 1 && recalc === 'yes'){
//do something
}
But when I try to add he 3rd argument it fails, the actions in the if statement are ignored
I've tried..
if((sheet_exists === 1) && (recalc === 'yes') && (qty_total !== new_qty_total)){
//do something
}
And...
if(sheet_exists === 1 && recalc === 'yes' && (qty_total !== new_qty_total)){
//do something
}
And...
if(sheet_exists === 1 && recalc === 'yes' && qty_total !== new_qty_total){
//do something

Why does 1ul << 64 return 1 instead of 0? : <p>Consider the following piece of code:</p>
<pre><code>// Simply loop over until 64 is hit.
unsigned long x = 0;
for (int i = 0; i <= 64; i++) {
if (i == 64) {
x = 1ul << i;
printf("x: %d\n", x);
}
}
</code></pre>
<p>We know that unsigned long is 64-bit wide, and left shifting 1 by 64 positions would become 1000...000 (64 zeros behind one), and would have been truncated to 0. However, the actual printout gives:</p>
<pre><code>x: 1
</code></pre>
<p>The strange thing is, if we just do </p>
<pre><code>printf("x: %d\n", (1ul << 64));
</code></pre>
<p>It would print 0. </p>
<p>Can anyone explain why this is happening? Why in the first case, the program mistakenly produces 1 instead of 0, but in the second case it's correct? </p>

Gradle mixing versions 27.1.1 and 26.1.0 : <p>I'm getting an error in my app-level build.gradle where on the first support library I am using, it tells me that all com.android.support libraries must use the exact same version specification and that it's found versions 27.1.1 and 26.0.2. In my app-level build.gradle, there is no line using 26.1.0. Also, all <code>compile</code> statements have been changed to <code>implementation</code>, the <code>compileSdkVersion</code> is 27 and the <code>targetSdkVersion</code> is 27. To attempt to find the culprit, I ran:</p>
<pre><code>./gradlew -q dependencies app:dependencies --configuration debugAndroidTestCompileClasspath
</code></pre>
<p>And got the following output:</p>
<pre><code>registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)

In Matplotlib, what axis attribute specifies the spacing between ticks? : <p>When generating a Matplotlib line or scatter plot, what axis attribute specifies the spacing between ticks? I do not want to <a href="https://stackoverflow.com/a/12608937/3585557">explicitly specify where each tick should be</a> as prompted by <a href="https://stackoverflow.com/q/12608788/3585557">this related question</a></p>
<pre><code>ax.ticks(np.arange(-100, 100, 5))
</code></pre>
<p>What is the matplotlib axis attribute that controls the tick spacing? It should behave something like the following.</p>
<pre><code>ax.set_x_tick_spacing(5)
</code></pre>
<p>This would use the same default <code>xlim</code> and origin point (usually 0) as the default settings.</p>

How can I check if my pm2 app NODE_ENV is getting set? : <p>So I just deployed a site with node and pm2 for the first time and I'm going back and doing some optimization and reading best practices, etc.</p>
<p>I read that you can get a lot of benefit by setting <code>NODE_ENV=production</code>.</p>
<p>I found this in the pm2 docs:</p>
<pre><code>[process.json]
"env_production" : {
"NODE_ENV": "production"
}
...
$ pm2 start process.json --env production
</code></pre>
<p>So, I did it but I have no idea if it is working. While trying to figure out how to check it I learned to try:</p>
<pre><code>$ node
> process.env.NODE_ENV
> undefined
</code></pre>
<p>So, that's not a good sign.. but, with my limited understanding of how the low level stuff works, I can guess that maybe pm2 launches each app as a separate node process? So maybe I'm not in the right process when I try to check it.</p>
<p>Also, I don't know if I have to make a new ~/.pm2/dump.pm2 file because maybe whenever that is maybe overriding the options I set? (because I used <code>pm2 startup</code>).</p>
<p>How do I check if my pm2 app's NODE_ENV is set?</p>

How to Print pdf from html with php or js (codeigniter)? : I'm currently facing an issue I can't really solve. I'm using MVC scheme with codeigniter. I'd like to dynamically print a pdf from a html view (either using javascript while clicking on a button or doing it with php after an ajax request) with some custom parameters, css, positions of elements etc.
The point is, all available libraries are not working for me. So far I've tried Tcpf, mpdf, html2pdf, dompdf, jspdf, fpdf.
In most cases, they don't have a good rendering for the css, so the elements are more or less printed without the imposed features.
Does anyone have any more suggestions? :)
Thanks a lot!

Export const arrow function or basic function? : <p>Which is better to do: export a <code>const</code> arrow function, like so:</p>
<pre><code>export const foo = () => 'bar'
</code></pre>
<p>or export a regular function, like so:</p>
<pre><code>export function baz() {
return 'bar';
}
</code></pre>
<p>They compile like so:</p>
<pre><code>exports.baz = baz;
function baz() {
return 'bar';
}
var foo = exports.foo = function foo() {
return 'bar';
};
</code></pre>
<p>It looks like using the const/arrow function combination declares an extra variable (<code>foo</code>), which seems to be an unnecessary extra step over the simple function declaration.</p>

Numbers OCR (Optical Recognition) in javascript : <p>I am looking for Javascript API for OCR or Machine Learning example (Tensorflow.js or any other) which can recognize numbers from the picture. I tried tesseract.js and OCRAD.js, but both do not work well with this kind of image. I only need numbers from this picture like 2.243 and 0048. I also put to tesseract.js settings, that it is numbers only, but it did not help much.</p>
<p>The picture is a photo of the digital device, which does not have API to connect and get data digitally. I would like to use webcam and javascript OCR and get these numbers periodically from this device to the list and build the graphs later.</p>
<p>I found a lot of examples for Tensorflow recognition of handwritten digits, but all of them can recognize only one digit, they cannot recognize a number consisting of more than 1 digits.</p>
<p>P.S. I do not want to spend a lot of time, actually I do not have this time :). Just want to reuse ready example.</p>

Define function in unix/linux command line (e.g. BASH) : <p>Sometimes I have a one-liner that I am repeating many times for a particular task, but will likely never use again in the exact same form. It includes a file name that I am pasting in from a directory listing. Somewhere in between and creating a bash script I thought maybe I could just create a one-liner function at the command line like:</p>
<pre><code>numresults(){ ls "$1"/RealignerTargetCreator | wc -l }

<p>I've tried a few things like using eval, using <code>numresults=function...</code>, but haven't stumbled on the right syntax, and haven't found anything on the web so far. (Everything coming up is just tutorials on bash functions).</p>

Getting an Kubernetes Ingress endpoint/IP address : <pre><code>Base OS : CentOS (1 master 2 minions)
K8S version : 1.9.5 (deployed using KubeSpray)
</code></pre>
<p>I am new to Kubernetes Ingress and am setting up 2 different services, each reachable with its own path.</p>
<p>I have created 2 deployments :</p>
<pre><code>kubectl run nginx --image=nginx --port=80
kubectl run echoserver --image=gcr.io/google_containers/echoserver:1.4 --port=8080
</code></pre>
<p>I have also created their corresponding services :</p>
<pre><code>kubectl expose deployment nginx --target-port=80 --type=NodePort
kubectl expose deployment echoserver --target-port=8080 --type=NodePort
</code></pre>
<p>My <code>svc</code> are :</p>
<pre><code>[root@node1 kubernetes]# kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
echoserver NodePort 10.233.48.121 <none> 8080:31250/TCP 47m
nginx NodePort 10.233.44.54 <none> 80:32018/TCP 1h
</code></pre>
<p>My NodeIP address is <code>172.16.16.2</code> and I can access both pods using</p>
<pre><code>http://172.16.16.2:31250 &
http://172.16.16.2:32018
</code></pre>
<p>Now on top of this I want to deploy an Ingress so that I can reach both pods not using 2 IPs and 2 different ports BUT 1 IP address with different paths.</p>
<p>So my Ingress file is :</p>
<pre><code>apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: fanout-nginx-ingress
spec:
rules:
- http:
paths:
- path: /nginx
backend:
serviceName: nginx
servicePort: 80
- path: /echo
backend:
serviceName: echoserver
servicePort: 8080
</code></pre>
<p>This yields :</p>
<pre><code>[root@node1 kubernetes]# kubectl describe ing fanout-nginx-ingress
Name: fanout-nginx-ingress
Namespace: development
Address:
Default backend: default-http-backend:80 (<none>)
Rules:
Host Path Backends
---- ---- --------
*
/nginx nginx:80 (<none>)
/echo echoserver:8080 (<none>)
Annotations:
Events: <none>
</code></pre>
<p>Now when I try accessing the Pods using the NodeIP address (172.16.16.2), I get nothing.</p>
<pre><code>http://172.16.16.2/echo
http://172.16.16.2/nginx

How do you pass/bind a value through a RaisedButton in Flutter? : <p>I have a ListView of RaisedButtons, where each RaisedButton looks like this. The <code>name</code> variable is different for each RaisedButton:</p>
<pre><code> new RaisedButton(
onPressed: _navigateToRoute,
child: new Text(name),
),
</code></pre>
<p>Tapping on a RaisedButton calls _navigateToRoute(): </p>
<pre><code> void _navigateToRoute() {
Navigator.of(context).push(new MaterialPageRoute<Null>(
builder: (BuildContext context) {
return new Scaffold(
body: new Text('A value with the word "Hello" should go here'),
);
},
));
}
</code></pre>
<p>When a specific RaisedButton is tapped (e.g. let's say we tap the first RaisedButton in the ListView, where <code>name = 'Hello'</code>), I would like to pass the <code>name</code> variable to the new route. How do I do that? Is there a way to store <code>name</code> in the <code>context</code> variable? Should I use another widget instead of RaisedButton?</p>
<p>I could use a <a href="https://docs.flutter.io/flutter/widgets/Navigator-class.html" rel="noreferrer">Named Navigator Route</a> but I don't want to hardcode a route for each item in my ListView.</p>
<p>I found <a href="https://github.com/flutter/flutter/issues/7877" rel="noreferrer">this Github issue</a>, and I'm not sure if it's the same thing I'm encountering.</p>

I am using switch after they have register their car that how many car they want to register. It need to get back to menu and led them to the second choice to update their information.
3rd is to print out which one they wanted to print out and they can key in without printing out all
4th, but for this 4th is to print out all.</p>

How to write unit tests for python tornado application? : <p>I want to try to write some code following TDD practice. I want to create simple app based on python's tornado framework. I was looking through the internet how people write tests for tornado and found something like this:</p>
<pre><code>class TestSomeHandler(AsyncHTTPTestCase):
def test_success(self):
response = self.fetch('/something')
self.assertEqual(response.code, 200)
</code></pre>
<p>Correct me if I'm wrong but it looks more like integration tests. Instead of it I'm trying to write simple unit test for some dummy handler. For example such one:</p>
<pre><code>class SomeHandler(BaseHandler):
@gen.coroutine
def get(self):
try:
from_date = self.get_query_argument("from", default=None)
datetime.datetime.strptime(from_date, '%Y-%m-%d')
except ValueError:
raise ValueError("Incorrect argument value for from_date = %s, should be YYYY-MM-DD" % from_date)
</code></pre>
<p>And test would look like:</p>
<pre><code>class TestSomeHandler(AsyncHTTPTestCase):
def test_no_from_date_param(self):
handler = SomeHandler()
with self.assertRaises(ValueError):
handler.get()
</code></pre>
<p>I know I miss at <code>get()</code> application and request. Not handled yet how to create them.</p>
<p>But my question is, do people write tests for tornado like in first example or somebody calls handlers inside of app? What pattern to follow? It would be nice if somebody have relevant code to share. </p>

How do you change the colour of a section title in a tableview? : <p>Here is what I have at the moment.</p>
<p><a href="https://i.stack.imgur.com/JYNrd.png" rel="noreferrer"><img src="https://i.stack.imgur.com/JYNrd.png" alt="enter image description here"></a></p>
<p>How do I refer to this so that I can change the text colour to match my index list? The <strong>sectionForSectionIndexTitle</strong> worked well for adding in the correct section title but how exactly does one access the title element? </p>
<p>Or is it impossible and I need to redraw the view and add it with <strong>viewForHeaderInSection</strong>?</p>

How to use XML with Android Studio : <p>I'm very new To Android Studio, but I am pretty good with Java but have never really tried out XML. Whenever I search the web I can't really find any good tutorials on XML, and when I do they are irrelevant and the code is different then the one Android Studio uses. Do any of you know any good tutorials that teach you how to use XML in Android Studio? Thanks.</p>
<p>P.S This is the XML that I'm referring to: <a href="https://gyazo.com/9b86f01828dc130f964e126561049827" rel="nofollow noreferrer">https://gyazo.com/9b86f01828dc130f964e126561049827</a></p>

Can I lose "constness" in the return type of an override virtual function? : <p>The following code compiles and runs, and no warning is emitted by either gcc or clang:</p>
<pre><code>#include <iostream>
struct Base {
virtual ~Base() = default;
virtual std::string const& get() = 0;
};
struct Derived: Base {
virtual std::string& get() override { return m; }
std::string m;
};
int main()
{
Derived d;
d.get() = "Hello, World";
Base& b = d;
std::cout << b.get() << "\n";
}
</code></pre>
<p>Is <code>std::string&</code> covariant with <code>std::string const&</code> then?</p>

Finding 2nd largest number in array (one look at array) : <p>I did a class earlier where we went through this kind of algorithm but can't find my code. How do I find the 2nd biggest number in an array with only 1 scan?</p>
<p>I was thinking about using nodes but that would screw up if the largest and 2nd largest one starts on same side. And an ugly way is to have two extra temp-variables and "find" the smaller one of them. </p>
<p>So anyone got any tip? Oh and it's java if you have the code.
In the meantime I'll try to search more on google!</p>

Printing all the integers from 0 to n in in descending order order using recursive method : <p>I made a little program to practice recursions, but I can't get it to work as intended as you can see. In its current state, the program kinda works but not like I want it to. </p>
<p>What I am looking for is to print values from int N to 0 in descending order rather than from 10 to N as it is currently in the code.</p>

return;
else {
DescendingRecursion(n + 1);
Console.Write(n + " ");
}

Issue when accessing hash by key : <p>I am doing my first Python project and I have the following code:</p>

perfomance mixing javascript and jquery : <p>There are lots of discussion about this topic, but I wanna clear my ambiguity or confusion - <strong>my mixed code make sense or not.</strong> </p>
<p>Previously I thought <code>Jquery</code> is most comfortable in every aspects, from easiness to the level of flexibility. There is no doubt we can create the vast and robust client side application with the usage of Jquery.</p>
<p>So I had been using <code>Jquery</code> even in small and simple tasks. But while concerning about performance, I found peoples are recommending pure JavaScript if you can. I read in lot of forums, question/answers about the performance, then I realized I am using Jquery unnecessarily.</p>
<p>For example, I had using to do simple task </p>
<pre><code>var value = $('#div').text();
</code></pre>
<p>instead of </p>
<pre><code>var value = document.getElementById('div').innerHTML;
</code></pre>
<p>In addition, I had used maximum <code>$.each</code> even in simple selection which can be done with <code>document.querySelector</code> or pure javascript <code>for</code> loop </p>
<p>I can't avoid the usage of Jquery, but can minimize. So, browser have to load jquery. </p>
<p>Now I have minimized jquery usage in external <code>.js</code> file, using pure javascript code for simple task and using jquery for only complex. </p>
<p><em>Now my question is</em> </p>
<p><strong>Now would my perfomance be better and fast than previous my way (where I had used jquery only) ?</strong></p>
<p>OR</p>
<p><strong>if $ is initialized once, does it affect other pure javascript code ?</strong></p>
<p>To be more clear,</p>
<p><strong>Does second one is faster than first one ?</strong></p>
<p><strong>Jquery only</strong></p>
<pre><code>function purchase(){
$.ajax({
url:"fetch.php",
method:"POST",
data:{prch_id:'pty'},
beforeSend: function() {
$('.pty').html('Processsing');
},
success:function(data){
$('.pty').html(data);
auto_select();
}
});
}
</code></pre>
<p><strong>Javascript with Jquery</strong></p>
<pre><code>function purchase(){
var http = null;
if(window.XMLHttpRequest){
http = new XMLHttpRequest();
}
else{
http = new ActiveXObject('Microsoft.XMLHTTP');
}
var vars = "prch_id=pty";
http.open('POST','fetch.php',true);
http.setRequestHeader('Content-type','application/x-www-form-urlencoded');
http.onreadystatechange = function(){
if(http.readyState==4 && http.status==200){
var data = http.responseText;
$('.pty').html(data);
auto_select();
}
}
http.send(vars);
$('.pty').html('Processsing');
}
</code></pre>
<p>if we used pure JavaScript only - it is sure it is speedy, but I want to know mixing of jquery and JavaScript improves or does not make any sense.</p>

How to use APNs Auth Key (.p8 file) in C#? : <p>I'm trying to send push notifications to iOS devices, using token-based authentication.</p>
<p>As required, I generated an APNs Auth Key in Apple's Dev Portal, and downloaded it (it's a file with p8 extension).</p>
<p>To send push notifications from my C# server, I need to somehow use this p8 file to sign my JWT tokens. How do I do that?</p>
<p>I tried to load the file to X509Certificate2, but X509Certificate2 doesn't seem to accept p8 files, so then I tried to convert the file to pfx/p12, but couldn't find a way to do that that actually works.</p>

Getting a footer to stay on the bottom : <p>I've been all over this website and I've read every question about footers not working that I can find. I've implemented every one of them to my page and I can't get a single solution for my site. I'm new to CSS and HTML, so please bear with me. </p>
<p>I have a Big Cartel Page and I use the Sidecar theme. I have been playing with code, changing fonts, altering image sizes and mostly just adding small tweaks here and there. I would love to add a footer with my contact info (phone, email, copyright, etc) that sits at the bottom of every page. </p>
<p>My homepage and FAQ pages are very long, and I need the footer to sit out of sight until the user scrolls all the way past the text to the bottom. But I also have many product pages that vary in length, but are sometimes short enough that I worry about the footer creeping up from the bottom. </p>
<p>I have tried every answer on <a href="https://stackoverflow.com/questions/3443606/make-footer-stick-to-bottom-of-page-correctly?rq=1">this page</a>, and I'm sorry in advance for not knowing how to share all of my trials well. I have tried every position I can find (fixed, static, relative, absolute) and I don't know what else I should try. Every one of them has the footer stretched across the screen well above the bottom of the page. </p>
<p>I can't figure out if it's the theme I'm using on Big Cartel to blame, or my own shortcomings with code. Probably the latter. Either way, I'd love any insight, as the main source of my trials is that link I posted, and it's from several years ago. </p>
