Heroku Postgresql with Google Datastudio : <p>I'm having troubles to connect an existing heroku database to Google Datastudio. I'm trying to add the connection and I get the following:</p>
<blockquote>
<p>Access denied, please check your username and password.</p>
</blockquote>
<p>Now, I'm 100% sure that I'm correct on those credentials and the problem comes from somewhere else.</p>
<p>I've tried with different setup, either a free or a paid PSQL instance, nothing works.</p>
<p>I've also setup a dummy account on <a href="http://elephantsql.com" rel="noreferrer">elephantsql</a> and the connection worked the first time without any issue.</p>
<p>Do you have any idea of the cause of that problem?</p>
<p>Edit:</p>
<p>Just found <a href="https://www.en.advertisercommunity.com/t5/Data-Studio/Heroku-Postgres-lt-gt-Google-Data-Studio/m-p/1031729" rel="noreferrer">https://www.en.advertisercommunity.com/t5/Data-Studio/Heroku-Postgres-lt-gt-Google-Data-Studio/m-p/1031729</a> which is not helpful at the time of writing this post.</p>

Variable seems to not get set on mobile devices : <p>I'm reading an image file and rescaling it to send it to a server. In order to properly rescale it I need to change the orientation, since some pictures are taken with a mobile device camera. In order to do this rotation I did the following using the <a href="https://github.com/exif-js/exif-js" rel="noreferrer">exif.js</a> library:</p>
<pre><code>EXIF.getData(img, function() {
alert(this.exifdata.Orientation);
orientation = this.exifdata.Orientation;
alert(orientation);
}
</code></pre>
<p>If <code>this.exif.data.Orientation</code> was, for example 6, the following output would be desierd: "6", "6".</p>
<p>This works when a file is uploaded via my computer. However, when uploaded from a mobile device camera, the output is "6" and then "0", no matter what value <code>orientation</code> had before.</p>
<p>Why does this happen?</p>
<p><strong>Note:</strong> I'm only running on one thread. So the variable could not have been set externally during execution of these lines.</p>

Unsure why code isn't working : <p>I am unsure why my code is not working:</p>
<pre><code>public int caughtSpeeding(int speed, boolean isBirthday) {
if(isBirthday=true){
speed = speed - 5;
}
if(speed<=60){
return 0;
}
if(speed>=81){
return 2;
}
return 1;
}
</code></pre>
<p>The question is:</p>
<p>You are driving a little too fast, and a police officer stops you. Write code to compute the result, encoded as an int value: 0=no ticket, 1=small ticket, 2=big ticket. If speed is 60 or less, the result is 0. If speed is between 61 and 80 inclusive, the result is 1. If speed is 81 or more, the result is 2. Unless it is your birthday -- on that day, your speed can be 5 higher in all cases.</p>

Delete a Vue child component : <p>I'm really stuck on this one.I have created a Vue (2.0) component that is made up of child components, it's all being Webpacked etc. For example, this is the parent:</p>
<pre><code><div>
<h1>This is just a title for lulz</h1>
<rowcomponent v-for="row in rows" :row-data="row"></rowcomponent>
</div>
</code></pre>
<p>which has a prop of <code>rows</code> passed to it which looks something like this:</p>
<pre><code>rows: [{ sometext: "Foo"} , { sometext: "Bar" }]
</code></pre>
<p>So my row component looks like this: </p>
<pre><code><div>{{ this.sometext }} <button @click="deleteRow">Delete Row</button></div>
</code></pre>
<p>And I feel like it should be really easy to set a method on the <code>rowcomponent</code> that is something like this:</p>
<pre><code>deleteRow() {
this.delete();
}
</code></pre>
<p>Do I need to $emit something to the parent with the index of the row in it to remove it? It's driving me crazy. All the examples seem to suggest it would be easy to do, but not in the case where you have child components that want to delete themselves.</p>

Flyway: Found non-empty schema(s) "public" without schema history table! Use baseline() - on Empty database : <p>I am trying to configure flyway with kotlin Spring boot, jpa and postgreSQL. My gradle dependencies are: </p>
<pre><code>dependencies {
implementation('org.springframework.boot:spring-boot-starter-data-jpa')
implementation('org.springframework.boot:spring-boot-starter-web')
implementation('com.fasterxml.jackson.module:jackson-module-kotlin')
implementation('org.flywaydb:flyway-core')
implementation('com.google.code.gson:gson')
implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
implementation("org.jetbrains.kotlin:kotlin-reflect")
runtimeOnly('org.postgresql:postgresql')
testImplementation('org.springframework.boot:spring-boot-starter-test')
}
</code></pre>
<p>My application.properties file is:</p>
<pre><code>spring.datasource.driverClassName=org.postgresql.Driver
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.datasource.url=jdbc:postgresql://${JDBC_DATABASE_URL}/jpaTestDatabase
spring.datasource.username=${JDBC_DATABASE_USERNAME}
spring.datasource.password=${JDBC_DATABASE_PASSWORD}
flyway.baseline-on-migrate=true
flyway.locations=classpath:src/main/kotlin/db/migration
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=validate
spring.session.store-type=none
</code></pre>
<p>Creating tables and entries using jpa and hibernate works as expected.
However a sample migration on an empty database results in:</p>
<pre><code>org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'flywayInitializer' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]:
Invocation of init method failed; nested exception is org.flywaydb.core.api.FlywayException:
Found non-empty schema(s) "public" without schema history table! Use baseline() or set baselineOnMigrate to true to initialize the schema history table.
</code></pre>
<p>my directory structure is the default one generated by spring initializr and my migrations are in: <code>demo/src/main/kotlin/db/migration</code></p>
<p>I only have a single migration which is the kotlinized version of the example migration found <a href="https://flywaydb.org/documentation/migrations" rel="noreferrer">here</a> which I adapted to look line this:</p>
<pre><code>class V1__Sample : BaseJavaMigration() {
override fun migrate(context: Context?) {
val statement = context?.connection?.prepareStatement(
"""
CREATE TABLE article (
id bigserial primary key,
name varchar(20) NOT NULL,
desc text NOT NULL
);
"""
)
statement.use { it?.execute() }
}
}
</code></pre>
<p>What am I missing here? Why does Flyway keep complaining about finding non-empty schema(s) "public" without schema history table, when the database is completelly empty (clean docker image)?</p>

when you create a library, do you need to provide the cs file or dll file is enough : <p>As title, I would like to make a basic library of math functions but I would like to know if user need my source code (.cs class) or just providing the .dll file and user adding it in references </p>

Error referencing DLL in C# "A reference to xxx.DLL could not be added : <p>I am trying to reference a DLL in a C# application. The DLL has been written in C++. To make the reference I am right-clicking on the "references" section on the solution explorer and choosing "Add Reference" and then browsing to it. Every time I try, I get an error message</p>
<blockquote>
<p>A reference to xxx.DLL could not be added. Please make sure that the
file is acessible, and that it is a valid assembly or COM component.</p>
</blockquote>
<p>Having done some googling, I noted that many people suggest using TlbImp.exe to get a valid DLL, but when I run it at the command line, I get,</p>
<blockquote>
<p>TlbImp:error TI0000 : The input file xxx.dll is not a valid type
library.</p>
</blockquote>
<p>It did occur to me that the DLL in question might just be badly written (the chap who wrote it is now on holiday) so I worked through <a href="https://msdn.microsoft.com/en-GB/library/ms235636.aspx" rel="nofollow noreferrer">this</a> microsoft walkthrough to create a new, very simple dll, and I got the same result.</p>
<p>I am using VS2015, although I did previously have an install of VS2013 Express. I also tried the same process on another machine with VS2013 and VS2010. The effects were the same.</p>
<p>Does anyone have any ideas?</p>

What does Kubernetes cronjobs `startingDeadlineSeconds` exactly mean? : <p>In Kubernetes <a href="https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/" rel="noreferrer">cronjobs</a>, It is stated in the <a href="https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/#cron-job-limitations" rel="noreferrer">limitations section</a> that </p>
<blockquote>
<p>Jobs may fail to run if the CronJob controller is not running or broken for a span of time from before the start time of the CronJob to start time plus startingDeadlineSeconds, or if the span covers multiple start times and concurrencyPolicy does not allow concurrency.</p>
</blockquote>
<p>What I understand from this is that, If the <code>startingDeadlineSeconds</code> is set to <code>10</code> and the cronjob couldn't start for some reason at its scheduled time, then it can still be attempted to start again as long as those <code>10</code> seconds haven't passed, however, after the <code>10</code> seconds, it for sure won't be started, is this correct?</p>
<p>Also, If I have <code>concurrencyPolicy</code> set to <code>Forbid</code>, does K8s count it as a fail if a cronjob tries to be scheduled, when there is one already running?</p>

An error occurs in dmeo of HUOBI API : Thank you for viewing.
I am an engineer in Japan.
I am glad that you can understand that you are not very good at English.
Well, it is the main subject.
programming language is PHP.
I am trying to obtain account information by using HUOBI's API.
https://github.com/huobiapi/REST-API-demos/tree/master/REST-PHP-DEMO
An error occurred when get_balance() was executed by changing the setting of "demo.php" to my ID and password.
The details of the error are as follows.
object(stdClass)#2 (4) {
["status"]=>
string(5) "error"
["err-code"]=>
string(44) "account-get-balance-account-inexistent-error"
["err-msg"]=>
string(64) "account for id `*,***,***` and user id `×,×××,×××` is not exist"
["data"]=>
NULL
}
`*,***,***` is my UID!!
`×,×××,×××` id Next number of UID（UID＋1）
Source is exactly as git goes up.
I will wait for the answer.

Need to Extract multi value key pare using regex : In My Web test project one request return below json in body tag. And I wants to extract all TimeEntryIds of Each FieldItem. using single RegEx extractor (Post porcessors) because I need to pass each TimeEntryid in successive web request.
{
"InvoiceItemId": 0,
"JobId": 9999,
"CreatedDate": "0001-01-01T00:00:00Z",
"LastUpdatedDate": "0001-01-01T00:00:00Z",
"FieldItem": [
{
"root": false,
"TimeEntryId": 1,
"UpdatedDate": "2019-07-19T13:14:29.823Z"
},
{
"root": false,
"TimeEntryId": 2,
"UpdatedDate": "2019-07-19T13:14:29.823Z"
},
{
"root": false,
"TimeEntryId": 3,
"UpdatedDate": "2019-07-19T13:14:29.823Z"
},
{
"root": false,
"TimeEntryId": 4,
"UpdatedDate": "2019-07-19T13:14:29.823Z"
}
]
}
Is there any short cut to get the all Key\Value pare in single RegEx extractor.

How to convert a number to a linked list in C++ : <p>I am starting out learning about linked lists and am trying to solve a programming problem. The output needs to be a number represented as a linked list. For example, if the number is 123, the linked list needs to be 3->2->1. </p>
<p>According to my implementation, I am doing all other functions beforehand and have the final output number as an int, and need to convert it to a linked list. I tried the following code.</p>
<pre><code> ListNode* numToLL(int sum){
ListNode* mainHead;
int remainder = sum % 10;
mainHead->val = remainder;
sum = sum / 10;
ListNode* head;
head = mainHead;
while (sum != 0){
ListNode* nextNode;
int remainder = sum % 10;
nextNode->val = remainder;
head->next = nextNode;
head = nextNode;
sum = sum / 10;
}
return mainHead;
}
</code></pre>
<p>I know this is incorrect, but I am not sure how to correct it. The error message for this says: "runtime error: member access within null pointer of type 'struct ListNode'" on the 3rd line inside the function.</p>

End of file in Perl - readline : At the moment I'm trying to get an Perl-script working. However, I do get an error, namely:
>readline() on closed filehandle IN at Test.pl line 368, <IN> line 65.
Line 368 of the perl-script looks like this:
>while(<IN>){
And refers to the configuration-input file, and the last line (line 65) looks like this:
>num_cpus = 40
So I guess, the configuration-input-file is not correct, or perl does not recognize that this is the end of the file.
Is there a way to solve this?

Laravel: what is the best practice to show errors in a modal when save a form? : <p>In my Laravel application (Bootstrap 4, jQuery and Axios) I have a page with multiple forms. Some forms are in a modal, but not all forms. </p>
<pre><code><form method="post">
<div class="modal">
// show errors
// form fields
</div>
</form>
</code></pre>
<p>I will not use ajax for posting this form. What is the best practice to show errors in a modal, when post a form when there are many others forms on the same page?</p>
<p>The problem now is: when a user posts a form with a field error, Laravel redirects the user back to the page, with the modal closed. When the user opens the modal, he shees the error in the modal.
What is the best practice to prevent this?</p>

<p>A2 B2 C2 <strong>D2</strong> E2 ---- J2 K2 L2 <strong>M2</strong> N2 ---- O2 P2 Q2 <strong>R2</strong> S2</p>
<p>A3 B3 C3 <strong>D3</strong> E3 ---- J3 K3 L3 <strong>M3</strong> N3 ---- O3 P3 Q3 <strong>R3</strong> S3</p>
<p>And so on for 200 rows.</p>
<p>What I want to be able to do in Excel is doubleclick on a cell in the D, M or R column and delete the respective grouping and have that section of the row shift up. For example, I doubleclick on <strong>D2</strong> and A2, B2, C2, D2 and E2 are deleted, shifting up A3, B3, C3, D3 and E3. All other cells remain the same. </p>

R Vector Values Overwrite in Function : <p><strong>specific problem i'm solving:</strong> </p>
<p>Create a character vector with length of number-of-rows-of-iris-dataset, such that, each element gets a character value – “greater than 5″ if the corresponding ‘Sepal.Length’ > 5, else it should get “lesser than 5″.</p>
<p>This works: </p>
<pre><code>char_vect <- c(seq(1:nrow(iris)))
for (i in char_vect) {
if (iris$Sepal.Length[i] > 5) {
char_vect[i] <- ("greater than 5") } else {
char_vect[i] <- ("less than 5")
}
}
</code></pre>
<p>But for some reason, if I define char_vect as follows, I get funny responses:</p>
<pre><code>char_vect <- iris$Sepal.Length
for (i in char_vect) {
if (iris$Sepal.Length[i] > 5) {
char_vect[i] <- ("greater than 5") } else {
char_vect[i] <- ("less than 5")
}
}
</code></pre>
<p>Although the vectors I'm starting off with are different in the two cases, the function is the same and is overwriting the original vectors so shouldn't their values be irrelevant as long as their lengths are equivalent?</p>
<p>When I look at what the output of the second option is, I'm even more confused since it looks like some the function overwrote some of the original values but not all of them ... </p>
<p>My hunch is that this has to do with the fact that option 1 defines char_vect as integers while option 2 is numeric? But I don't understand why a comparison operator wouldn't work equally on integers and numeric. Looking at the output of option 2, there also seems to be integers that the function did not work on. </p>
<p>much thank from a R novice!</p>

Evaluating bash "&&" exit codes behaviour : <p>We had a recent experience with bash that even we found a solution, it keeps twisting my mind. How does bash evaluates the <code>&&</code> expression in terms of return codes?</p>
<p>Executing this script, that should fail because <code>myrandomcommand</code> does not exist:</p>
<pre><code>#!/bin/bash
set -e
echo "foo"
myrandomcommand
echo "bar"
</code></pre>
<p>The result is the expected one:</p>
<pre><code>~ > bash foo.sh
foo
foo.sh: line 6: myrandomcommand: command not found
[exited with 127]
~ > echo $?
127
</code></pre>
<p>But changing slightly the code using the <code>&&</code> expression:</p>
<pre><code>#!/bin/bash
set -e
echo "foo"
myrandomcommand && ls
echo "bar"
</code></pre>
<p>The <code>ls</code> statement is not executed (since the first statement fails and does not evaluate the second statement), but the script behaves very different:</p>
<pre><code>~ > bash foo.sh
foo
foo.sh: line 6: myrandomcommand: command not found
bar # ('bar' is printed now)
~ > echo $?
0
</code></pre>
<p>We found out that using the expression between parenthesis <code>(myrandomcommand && ls)</code> it works as expected (like the first example), but I would like to know why.</p>

<p>I am new to Java, but I knew single equal (=) is used to assign. And double equals (==) is used to check if object is referred to the same location in memory. However, in this case I do not understand how the 'b' is being printed with a single equals, but I understand changing it to a double equals sign will not print it out</p>

Why use/develop Guice, when You have Spring and Dagger? : <p>To my knowledge, Dagger does generate code, while Guice and Spring rely on runtime processing, thus Dagger works faster, but requires more work on programmer side. Because of performance edge it's good for mobile (Android) development.</p>
<p>However, when we are left with Guice and Spring, the latter has lots of integrations. What's the point of developing/using Guice, if we can use Spring Framework (that does basically same thing, but offers ex. easier database access)?</p>
<p>Isn't Google trying to reinvent wheel by creating their own DI tool, instead of using (and possibly contributing to) Spring Framework?</p>

Admin or control panel : <p>I can do fine apps or websites, but there is a little use of them without control system.</p>
<p>How can I make an admin panel or how it's called. So that the user can add required components without coding. Just with some buttons and text areas, like in Wordpress.</p>
<p>I don't know how or what should I search on the Internet on this topic.</p>
<p>I know HTML/ JS / VUE basics / SASS. How can I use this knowledge to make a control system of my websites or apps. Or probably I should learn something new?</p>
<p>Please, advise how to reach my goal.</p>

C++ Operator Overloading in Class with Const Members? : <pre><code>class SomeClass {

SomeClass operator+(int num) {
SomeClass newSomeClass;

};
int main() {
SomeClass someClass;
SomeClass newClass;
newClass = someClass + 3;
}

<p>I don't understand why the above doesn't compile, but does so when the const related code is removed.</p>

Pass value from JavaScript to code behind C# : I need to pass the array value from code behind asp.net C#.
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Task', 'Hours per Day'],
['Work', 11],
['Eat', 2],
['Commute', 2],
['Watch TV', 2],
['Sleep', 7]
]);
var options = {
title: 'My Daily Activities'
};
var chart = new google.visualization.PieChart(document.getElementById('piechart'));
chart.draw(data, options);
}
</script>
Since the data changes dynamically I need to pass the value.

How to read/parse Content from OkNegotiatedContentResult? : <p>In one of my API actions (<code>PostOrder</code>) I <em>may</em> be consuming another action in the API (<code>CancelOrder</code>). Both return a JSON formatted <code>ResultOrderDTO</code> type, set as a <code>ResponseTypeAttribute</code> for both actions, which looks like this:</p>
<pre><code>public class ResultOrderDTO
{
public int Id { get; set; }
public OrderStatus StatusCode { get; set; }
public string Status { get; set; }
public string Description { get; set; }
public string PaymentCode { get; set; }
public List<string> Issues { get; set; }
}
</code></pre>
<p>What I need is reading/parsing the <code>ResultOrderDTO</code> response from <code>CancelOrder</code>, so that I can use it as response for <code>PostOrder</code>. This is what my <code>PostOrder</code> code looks like:</p>
<pre><code>// Here I call CancelOrder, another action in the same controller
var cancelResponse = CancelOrder(id, new CancelOrderDTO { Reason = CancelReason.Unpaid });
if (cancelResponse is OkNegotiatedContentResult<ResultOrderDTO>)
{
// Here I need to read the contents of the ResultOrderDTO
}
else if (cancelResponse is InternalServerErrorResult)
{
return ResponseMessage(Request.CreateResponse(HttpStatusCode.InternalServerError, new ResultError(ErrorCode.InternalServer)));
}
</code></pre>
<p>When I use the debugger, I can see that the <code>ResultOrderDTO</code> it is there <em>somewhere</em> in the response (looks like the <code>Content</code>) as shown in the pic below:</p>
<p><a href="https://i.stack.imgur.com/dqXJT.png" rel="noreferrer"><img src="https://i.stack.imgur.com/dqXJT.png" alt="Debugger"></a></p>
<p>but <code>cancelResponse.Content</code> does not exist (or at least I don't have access to it before I cast my response to something else) and I have no idea about how to read/parse this <code>Content</code>. Any idea?</p>

React-native Timeout when connecting to remote debugger in windows : <p>I am new to React-Native and android app development as a whole. While i try to run remote debugger in Android Emulator (Pixel 2 phone), I get the following error in the emulator: <a href="https://i.stack.imgur.com/aoisd.png" rel="noreferrer"><img src="https://i.stack.imgur.com/aoisd.png" alt="Error on Emulator"></a></p>
<p>Then after, even if I stop remote debugging, the application won't run on the emulator (i.e. nothing is rendered into the emulator screen). I need to run the project again. </p>
<p>Following is the auto-generated debugger URL: <a href="http://10.0.2.2:8081/debugger-ui" rel="noreferrer">http://10.0.2.2:8081/debugger-ui</a></p>
<p>How can I Fix this problem? </p>

<p>I also want to start a new Activity out of that alertbox (which doesn´t work either, i guess its because of the wrong context too)
