SQL Granting already existing rights to users / revoking them : <p>I have to answer some questions based on the statements below. Initially, user A is the owner of relation R, and no other user holds privileges on R. The following are executed:</p>
<pre><code>By A: GRANT INSERT ON R TO B WITH GRANT OPTION;
By B: GRANT INSERT ON R TO C WITH GRANT OPTION;
By C: GRANT INSERT ON R TO D WITH GRANT OPTION;
By D: GRANT INSERT ON R TO B WITH GRANT OPTION;
By B: REVOKE INSERT ON R FROM C CASCADE;
</code></pre>
<p>The questions are: What happens when D grants privileges to B, but they already exist? And what users still have the privileges after the last line is executed?</p>

What is the most feasible way to store large array data while being able to access it from a web browser? : <p>I have come across many ways to do this, but, either a third party resource is needed or the solution is not practical to implement.</p>
<p>What I need to store is an immense amount of data (an array with 700 nested arrays and 10 entries in each array). Some methods I've thought of are listed below together with their drawbacks:</p>
<ol>
<li>Using JSON:<br>
It's just a lot of work on the browser. The browser will freeze when I loop through the array.</li>
<li>Using an SQL database
I won't be able to run my webpage in any computer. I will have to install PHP and SQL in every computer I wish to run my webpage in.</li>
<li>Using a C++ program to handle the heavy work
This will only work with chrome, where I can use the file system API.</li>
</ol>
<p>Note: the webpage won't be uploaded to the internet.</p>
<p>What would be best to do in this situation?</p>

During local development with Kubernetes/minikube, how should I connect to postgres database running on localhost? : <p>I've set up an application stack running on Google Kubernetes Engine + Google Cloud SQL. When developing locally, I would like my application to connect to a postgres database server running <em>outside</em> the cluster to simulate the production environment.</p>
<p>It seems that the way to do this is by defining an external endpoint as described here: <a href="https://stackoverflow.com/questions/43354167/minikube-expose-mysql-running-on-localhost-as-service">Minikube expose MySQL running on localhost as service</a></p>
<p>Unfortunately, I am not able to specify "127.0.0.1" as the Endpoint IP address:</p>
<pre><code>kubectl apply -f kubernetes/local/postgres-service.yaml
service "postgres-db" unchanged
The Endpoints "postgres-db" is invalid: subsets[0].addresses[0].ip:
Invalid value: "127.0.0.1": may not be in the loopback range (127.0.0.0/8)
</code></pre>
<p>So I am forced to bind postgres to my actual machine address.</p>
<p>It seems like there MUST be a way to map a port from my localhost into the local kubernetes cluster, but so far I can't find a way to do it. </p>
<p>Anybody know the trick? Or alternatively, can someone suggest an alternative solution which doesn't involve running postgres inside the cluster?</p>

Automate mailto process : <p>How can I automate the mailto process, instead of a new compose window pop up in one of the mail clients is it possible to have the email send in the background, thus not having the user to click send.</p>
<p>Overall I want to receive a email from one of the customers that contains there choice "Approved" or "Rejected" and have them simply press on either button and the email be sent automatically and then maybe after they have clicked on the button have it redirect them to a page stating what decision they made etc. </p>
<p>If it's not possible to automatically send a email from there inbox without there permission so to speak as it'll be automated is there a way to capture or get there email along with there choice and have that send to orders@macwearembroideryclothing.com </p>

webkit box orient styling disappears from styling : <p>In my Angular app (I'm on version 4.3.1) I'm adding a CSS ellipsis after multiple lines.<br>
For this, I use the following css code in Sass.</p>
<pre><code>.ellipsis {
-webkit-box-orient: vertical;
display: block;
display: -webkit-box;
-webkit-line-clamp: 2;
overflow: hidden;
text-overflow: ellipsis;
}
</code></pre>
<p>For some reason, the box-orient line simply gets removed from the styling by the transpile, causing the ellipsis to not work. This seems to happen in Angular and Ionic apps.</p>

3D scatterplots in Python with hue colormap and legend : <p>I have been searching for 3D plots in python with seaborn and haven't seen any. I would like to 3D plot a dataset that I originally plotted using seaborn pairplot. Can anyone help me with these 2 issues:</p>
<ol>
<li>I am not able to get same color palette as sns pairplot, e.g. how to get the color palette from figure 2 and apply to the points on figure 1?</li>
<li>The legend does not stick to the plot or does not show up as nice on pairplot, e.g. When I do <code>plt.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.,ncol=4)</code> I see the following error: anaconda2/lib/python2.7/site-packages/matplotlib/axes/_axes.py:545: UserWarning: No labelled objects found. Use label='...' kwarg on individual plots. warnings.warn("No labelled objects found. "</li>

how to create tables with linked coulmns in sql server : i'm trying to create a database for a simple C# application using sql server.
i'm new to this
this is what I had planned
Clients: Client_ID, Client_Name, Client_Status
Employees: Emp_ID, Emp_Name, Emp_Role
Jobs: Job_ID, Job_Date, Client_ID, Employee_ID, Hours_Spent
how do i make the "Client_ID, Employee_ID" columns in table Jobs linked or connected the original ones in the tables Clients and Employees? do I do it from SQL server management or from the c# code?

Creating a new column with True/False output : To give a situation say we have 2 columns in excel which holds following data. Column TF must be created as a new column.
1 Table
2 A B TF
3 ABC ABC TRUE
4 ABC BAC FALSE
5 #NA ABC #NA
The numbers on the side ranging 1-5 indicates the row number.
When the strings in column A and B match, return true else false. How do I create a new Column, with name "TF" to hold these values. If either A or B does not contain any value, TF should also not have any value.
I want to do this for rows starting from 3 all the way until the end.
Thanks in advance. Really appreciate any help!

Is it a best practice in Java to declare variables before give them as parameters : <p>Assuming this code :</p>
<pre><code>public static Dataset<Row> getData(SparkSession sparkSession,

.read()
.option("delimiter", "\\t")
.csv(pathToData);
StructType nSchema= newSchema(schema, schema.size(), dataset.columns().length);

How to use local proxy settings in docker-compose : <p>I am setting up a new server for our Redmine installation, since the old installation was done by hand, which makes it difficult to update everything properly. I decided to go with a Docker image but am having trouble starting the docker container due to an error message. The host is running behind a proxy server, which I think, is causing this problem, as everything else such as wget, curl, etc. is working fine.</p>
<p>Error message:</p>
<pre><code>Pulling redmine (redmine:)...
ERROR: Get https://registry-1.docker.io/v2/: dial tcp 34.206.236.31:443: connect: connection refused
</code></pre>
<p>I searched on Google about using Docker/Docker-Compose with a proxy server in the background and found a few websites where people had the same issue but none of these really helped me with my problem.</p>
<p>I checked with the Docker documentation and found a guide but this does not seem to work for me: <a href="https://docs.docker.com/network/proxy/" rel="noreferrer">https://docs.docker.com/network/proxy/</a></p>
<p>I also found an answered question here on StackOverflow: <a href="https://stackoverflow.com/questions/53477114/using-proxy-on-docker-compose-in-server">Using proxy on docker-compose in server</a> which might be the solution I am after but I am unsure where exactly I have to put the solution. I guess the person means the docker-compose.yml file but I could be wrong.</p>
<p>This is what my docker-compose.yml looks like:</p>
<pre><code>version: '3.1'
services:
redmine:
image: redmine
restart: always
ports:

environment:

Programmatically bind custom events for dynamic components in VueJS : <p>In my vuejs app I use dynamic component in the following way:</p>

<p><code>myComponent</code> is a prop on the parent component which hold the actual component to inject.
<code>myComponentProps</code> are also prop which holds the porps for the injected instance.</p>

<p>Any tip would be much appreciated! </p>

How to output the highest and lowest values selected after entering 10 numbers between 1 to 100 in C : I am trying to write a C program that can accept 10 numbers between 1 and 100. If values outside the range are entered an error message should be displayed.
I have managed to write the following code to check for the to check if the numbers are between 1 to 100
```
#include <stdio.h>
int main() {
int num1, num2, num3, num4, num5, num6, num7, num8, num9, num10;
printf("\nEnter the first number : ");
scanf("%d", &num1);
printf("\nEnter the second number : ");
scanf("%d", &num2);
printf("\nEnter the third number : ");
scanf("%d", &num3);
printf("\nEnter the fourth number : ");
scanf("%d", &num4);
printf("\nEnter the fifth number : ");
scanf("%d", &num5);
printf("\nEnter the sixth number : ");
scanf("%d", &num6);
printf("\nEnter the seventh number : ");
scanf("%d", &num7);
printf("\nEnter the eighth number : ");
scanf("%d", &num8);
printf("\nEnter the nineth number : ");
scanf("%d", &num9);
printf("\nEnter the tenth number : ");
scanf("%d", &num10);
if ((num1 <= 1 && num2 <= 1 && num3 <= 1 && num4 <= 1 && num5 <= 1 && num6 <= 1 && num7 <= 1 && num8 <= 1 && num9 <= 1 && num10 <= 1) &&
(num1 >= 100 && num2 >= 100 && num3 >= 100 && num4 >= 100 && num5 >= 100 && num6 >= 100 && num7 >= 100 && num8 >= 100 && num9 >= 100 && num10 >= 100)){
printf("good");
printf("Numbers are good");
}else{
printf("All numbers must be between 1 to 100");
}
return (0);
}
```
When i run the code i get this output "All numbers must be between 1 to 100" Even if the numbers i enter are between the range of 1-100. i expect the output to be "Numbers are good". Please help. | 0debug |

Resizing images with javascript on a JSF page in a ui:repeat : I need to resize images sitting in JSF's repeat loop.
This is the loop:
<ui:repeat value="#{searchResults.products}" var="product">
<img id="thumbnailId" src='#{product.thumbnailUrl}' class="img-responsive galleryproductimg" style="border: 0px solid blue; margin-top:10px;" />
</ui:repeat>
And my `javascript code`:
<h:outputScript target="head">
$(document).ready(function() {
console.log("ready to go");
var imgs = getElementsById("thumbnailId");
for (var i = 0; i < imgs.length; i++) {
var img = imgs[i];
img.onload = function () {
console.log("image is loaded");
}
resizeImage(img);
}
});
The methods called from this:
function getElementsById(elementID) {
var elementCollection = new Array();
var allElements = document.getElementsByTagName("*");
for(i = 0; i < allElements.length; i++) {
if(allElements[i].id == elementID)
elementCollection.push(allElements[i]);
}
return elementCollection;
}
And
function resizeImage(img) {
console.log("width, height, src " + img.width + ", " + img.height + ", " + img.src);
console.log("loaded? " + img.complete);
var width = img.width;
var height = img.height;
var constant = 100;
var ratio = width / height;
console.log("ratio " + ratio);
if(width > constant || height > constant) {
var newWidth = constant;
var newHeight = constant*ratio;
if(width > height) {
newWidth = constant;
newHeight = constant*ratio;
} else {
newWidth = constant*ratio;
newHeight = constant;
}
console.log("newWidth, newHeight " + newWidth + ", " + newHeight);
//img.width = newWidth;
//img.height = newHeight;
img.style.width = newWidth + "px;";
img.style.height = newHeight + + "px;";
console.log("img from url AFTER " + img.width + ", " + img.height);
}
console.log("==========================");
}
The code seems right, and works for one image. But not inside the repeat. The output I get is this:
ready to go
resizeImages called
width, height, src 84, 110, http://thumbs1.ebaystatic.com/m/mPlrV_wS_b1vK9avUQ22r9w/140.jpg

img from url AFTER 86, 110
==========================
2 image is loaded
So basically I'm not even getting the correct dimensions of the image at the start. For some reason the width is always 110. Any idea what's going on here? | 0debug |
Display issues on website after selecting language : <p><a href="https://www.hollandmarineparts.nl/" rel="nofollow noreferrer">Our website</a> has some display issues after selecting a language. Take <a href="https://www.hollandmarineparts.nl/de/" rel="nofollow noreferrer">This page</a> for example. When we view the page in German, the following becomes clear:</p>
<ul>
<li>The main slider is no longer able to slide</li>
<li>The language selector stops working</li>
<li>The middle section slider is half off the page and no longer able to slide.</li>
</ul>
<p>I suspect a javascript issue after the language selection is made. Yet all files are loaded correctly. We do not know where to start looking for the issue.</p>
<p>I do not expect an immediate solution, but I hope that someone can point us in the right direction.</p>

can someone help to write this code more efficiently please? : As you can see in first picture I'm checking that a certain value contains in a document from firestore and returns a boolean value.
now I'm calling that function in a build and based on that return value I'm changing a chip color(Second picture). Now the problem is maybe because I'm calling it in a build function so its being called continuously and on that build and it costing me aton of reads in firestore or maybe the function is inefficient idk ..... so can anyone help to write the code or give a more efficient way for this please ??

No constructor for type SwaggerGenerator can be instantiated using services from the service container and default values : <p>I'm trying to add Swagger to my project. The error received is as follows.</p>

<p>Since I haven't changed anything in Swagger binaries themselves, just installed the packages <em>Swashbuckle.AspNetCore</em> and <em>Swashbuckle.AspNetCore.Swagger</em> (both in version 4.0.1) I'm assuming that it's about the configuration.

How to find degree on a circle that is tangent to a point outside of that circle? : - I know the (x,y) of a point, P, outside of a circle.
- I know the (x,y) for the origin of a circle, O.
- I know the radius, r, of that circle.
How would I find what degree (i.e. 20 degrees, 270 degrees) is tangent to the point outside of the circle ?

How to best get a byte array from a ClientResponse from Spring WebClient? : <p>I'm trying out the new <code>WebClient</code> from Spring 5 (5.0.0.RC2) in a codebase that uses reactive programming and I've had success mapping the JSON response from an endpoint to a DTO in my app, which works very nice:</p>
<pre><code>WebClient client = WebClient.create(baseURI);
Mono<DTO> dto = client.get()
.uri(uri)
.accept(MediaType.APPLICATION_JSON)
.exchange()
.flatMap(response -> response.bodyToMono(DTO.class));
</code></pre>
<p>However, now I'm trying to the response body from an endpoint which uses Protocol Buffers (binary data served as <code>application/octet-stream</code>), so I'd like to get the raw bytes from the response, which I'll then map to an object myself.</p>
<p>I got it to work like this using <code>Bytes</code> from Google Guava:</p>
<pre><code>Mono<byte[]> bytes = client.get()
.uri(uri)
.accept(MediaType.APPLICATION_OCTET_STREAM)
.exchange()
.flatMapMany(response -> response.body(BodyExtractors.toDataBuffers()))
.map(dataBuffer -> {
ByteBuffer byteBuffer = dataBuffer.asByteBuffer();
byte[] byteArray = new byte[byteBuffer.remaining()];
byteBuffer.get(byteArray, 0, bytes.length);
return byteArray;
})
.reduce(Bytes::concat)
</code></pre>
<p>This works, but is there an easier, more elegant way to get these bytes?</p>

Why is dynamic array "constructor" much slower than SetLength and elements initialization? : <p>I was comparing performances between these two ways of initializing a dynamic array:</p>
<pre><code>Arr := TArray<integer>.Create(1, 2, 3, 4, 5);
</code></pre>
<p>and</p>
<pre><code>SetLength(Arr, 5);
Arr[0] := 1;
Arr[1] := 2;
Arr[2] := 3;
Arr[3] := 4;
Arr[4] := 5;
</code></pre>
<p>I've prepared a test and I've noticed that using the array "constructor" takes twice the time required by the other method.</p>
<p><strong>Test:</strong></p>
<pre><code>uses
DateUtils;
function CreateUsingSetLength() : TArray<integer>;
begin
SetLength(Result, 5);
Result[0] := 1;
Result[1] := 2;
Result[2] := 3;
Result[3] := 4;
Result[4] := 5;
end;
</code></pre>
<p>...</p>
<pre><code>const
C_COUNT = 10000000;
var
Start : TDateTime;
i : integer;
Arr : TArray<integer>;
MS1 : integer;
MS2 : integer;
begin
Start := Now;
i := 0;
while(i < C_COUNT) do
begin
Arr := TArray<integer>.Create(1, 2, 3, 4, 5);
Inc(i);
end;
MS1 := MillisecondsBetween(Now, Start);
Start := Now;
i := 0;
while(i < C_COUNT) do

Arr := CreateUsingSetLength();
Inc(i);
end;
MS2 := MillisecondsBetween(Now, Start);
ShowMessage('Constructor = ' + IntToStr(MS1) + sLineBreak + 'Other method = ' + IntToStr(MS2));

How do I store JWT and send them with every request using react : <p>So happy right know because I got my basic registration/authentication system going on.</p>
<p>so basically I got this :</p>
<pre><code>app.post('/login', function(req,res) {
Users.findOne({
email: req.body.email
}, function(err, user) {
if(err) throw err;
if(!user) {
res.send({success: false, message: 'Authentication Failed, User not found.'});
} else {
//Check passwords
checkingPassword(req.body.password, user.password, function(err, isMatch) {
if(isMatch && !err) {
//Create token
var token = jwt.sign(user,db.secret, {
expiresIn: 1008000
});
res.json({success: true, jwtToken: "JWT "+token});
} else {
res.json({success: false, message: 'Authentication failed, wrong password buddy'});
}
});
}
});
});
</code></pre>
<p>Then I secure my /admin routes and with POSTMAN whenever I send a get request with the jwt in the header everything works perfectly.</p>
<p>Now here is the tricky part, basically When i'm going to login if this a sucess then redirect me to the admin page, and everytime I try to access admin/* routes I want to send to the server my jwToken but the problem is, how do I achieve that ? I'm not using redux/flux, just using react/react-router.</p>
<p>I don't know how the mechanic works.</p>
<p>Thanks guys</p>

get the coordinates and use them in android : I have successfully managed to get the current gps coordinates by calling requestLocationUpdates like this:
Criteria criteria = new Criteria();
provider = locationManager.getBestProvider(criteria, false);
if( provider != null){
locationManager.requestLocationUpdates(provider, 400, 1, this);
}
And my "onLocationChanged" is updating this position according to my criterias.
@Override
public void onLocationChanged(Location location) {
Log.d(TAG, "location is" + location);
double lat = (location.getLatitude());
double lng = (location.getLongitude());
String coordinates = (String.valueOf(lat) + "," + String.valueOf(lng));
longitudeField.setText(coordinates);
}
Now in my app I want to pass the latitude and longitude to firebase together with an image and some other information.
So I have another method that is taking the url from captured image and sending the image to firebase together with two strings that are the current date and time.
private void uploadFile() {
final String dateStamp = new SimpleDateFormat("yyyy-MM-dd").format(new Date());
final String timeStamp = new SimpleDateFormat("HH:mm:ss").format(new Date());
if (mImageUri != null) {
StorageReference fileReference = mStorageRef.child(System.currentTimeMillis()
+ "." + getFileExtension(mImageUri));
mUploadTask = fileReference.putFile(mImageUri)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
mProgressBar.setProgress(0);
}
}, 500);
Toast.makeText(MainActivity.this, "Upload successful", Toast.LENGTH_LONG).show();
Upload upload = new Upload(
taskSnapshot.getDownloadUrl().toString(), timeStamp, dateStamp);
String uploadId = mDatabaseRef.push().getKey();
mDatabaseRef.child(dateStamp).child(uploadId).setValue(upload);
}
})
**QUESTION:**
*How is the approach to getting the latitude and longitude in form of String so I can use it in my method for passing data to firebase?*

passing an object to a function in a the same class to initialize the values, but not by reference : <p>I'm looking for some clarification and confirmation that this is indeed doing nothing.</p>
<p>Say I have an object</p>
<pre><code>public class Person
{
public string Name { get; set; }
}
</code></pre>
<p>and I am going to use this object and for some reason it has to be initialized, which should happen in the constructor but for this example its going to happen in a call to an initialize function</p>
<pre><code>public class myClass
{
private void doingSomething()
{
Person p = new Person();
Initialize(p);
}
private void Initialize(Person person)
{
person.Name = "";
}
}
</code></pre>
<p>This is just a waste correct. If I really wanted to change the values doesn't it have to be passed using ref, out, or returning a different Person?</p>
<p>If I'm wrong i'd appreciate an explanation. I found this while looking through some old code and feel confused because I can't believe it's there.</p>

Why is my java lambda with a dummy assignment much faster than without it? : <p>I know that making judgements of Java microbenchmarks is extremely fraught, but I'm seeing something that seems odd, and I'd like to get some explanation for it.</p>
<p>Note that I'm not using the <a href="http://openjdk.java.net/projects/code-tools/jmh/" title="JMH">JMH</a> framework for this. I'm aware of it, but I didn't want to go to that length for this.</p>
<p>I'll provide the entire code sample, but in short, when I test the performance of these two methods</p>
<pre><code>private FooPrime[] testStreamToArray(ArrayList<Foo> fooList) {
return (FooPrime[]) fooList.stream().
map(it -> {
return new FooPrime().gamma(it.getAlpha() + it.getBeta());
}).
toArray(FooPrime[]::new);
}
private FooPrime[] testStreamToArray2(ArrayList<Foo> fooList) {
return (FooPrime[]) fooList.stream().
map(it -> {
int stuff = it.getAlpha().length();
return new FooPrime().gamma(it.getAlpha() + it.getBeta());
}).
toArray(FooPrime[]::new);
}
</code></pre>
<p>I find very surprising results. In the larger code sample, I'm measuring four different ways of doing this, and the first three are very close in performance. They all run about 50k ns per iteration. However, the second code sample consistently runs just under half of that total. That's right. It's not slower, it's quite a bit faster.</p>
<p>The last run shows numbers like this:</p>
<pre><code>manualcopy:54575 ns
toarray:53617 ns
streamtoarray:52990 ns
streamtoarray2:24217 ns
</code></pre>
<p>Each run has numbers similar to these.</p>
<p>I'll now provide the entire class and base class. Note that I do have a "warm-up" pass, where I execute the methods under test a few thousand times before starting the timings. Also note that although this runs "testStreamToArray2" last, I also tried moving that block to the first test, and the numbers come out about the same. The commented out lines are there to convince me that the methods are actually doing something (the timings are still about the same with those lines not commented out).</p>

How to set jacoco code coverage levels to module in gradle : <p>I'm using gradle 4.3.1 with the jacoco plugin and I am able to ensure a certain level of code coverage in a a multi module project. This works great when I set the <strong>element</strong> to <strong>CLASS</strong> or <strong>PACAKAGE</strong>, but I'm stumped on how to get it work for the module. </p>
<p>Looking <a href="http://www.jacoco.org/jacoco/trunk/doc/api/org/jacoco/core/analysis/ICoverageNode.ElementType.html" rel="noreferrer">here</a> I think what I want is <strong>BUNDLE</strong> or <strong>GROUP</strong>, but then jacoco does not break when I go under the coverage amount.</p>
<p>Here is an example of what I have that does work for package level coverage enforcement :</p>
<pre><code>jacocoTestCoverageVerification {
violationRules {
rule {
// should be element = 'BUNDLE' or 'GROUP'?
element = 'PACKAGE'
limit {
minimum = 0.9
}
includes = ['com.mypackage.*']
}
}
}
</code></pre>
<p>When I change the element value to BUNDLE the build does not fail regardless of coverage. Again I'd like to be able to control the expectation at the module level.</p>
<p>Here is my gradle version information:</p>
<pre><code>------------------------------------------------------------
Gradle 4.3.1
------------------------------------------------------------
Build time: 2017-11-08 08:59:45 UTC

<p>I'm guessing I'm missing something pretty simple, since I don't think I'm the first to try to do this. Any help would be appreciated!</p>
