Double vs Float - Java : <p>Well I have following program. It is given by my teacher for fun. I got surprise about the result. </p>
<p><strong>Code:</strong></p>
<pre><code>public class Testing {
public static void main(String[] args) {
float piF = 3.141592653589793f; // value assigned has float precision
double piD = 3.141592653589793; // value assigned has double precision
final double THRESHOLD = .0001;
if( piF == piD)
System.out.println( "piF and piD are equal" );
else
System.out.println( "piF and piD are not equal" );
if( Math.abs( piF - (float) piD ) < THRESHOLD )
System.out.println( "piF and piD are considered equal" );
else
System.out.println( "piF and piD are not equal" );
}
}
</code></pre>
<p><strong>Result:</strong></p>
<pre><code>piF and piD are not equal
piF and piD are considered equal
</code></pre>
<p>Well why piF and piD are not equal ? And what actually <code>Math.abs()</code> do that makes both same ?</p>

React-router: Using <Link> as clickable data table row : <p>I'm new to using ReactJS and react-router. I want a clickable table row and something like the following setup:</p>
<pre><code><Link to=“#”>
<tr>
<td>{this.props.whatever1}</td>
<td>{this.props.whatever2}</td>
<td>{this.props.whatever3}</td>
</tr>
</Link>
</code></pre>
<p>but I know you can't put <code><a></code> tags between the <code><tbody></code> and <code><tr></code> tags. How else can I accomplish this?</p>
<p>PS: I prefer not to use jQuery if possible.</p>

How to bind MVC checkboxes to model : <p>I have a view which outputs a list of questions. The user will select questions they want included in a report and then submit the form.</p>
<p>My view looks like:</p>
<pre><code>@using (Html.BeginForm("Step6", "Home", FormMethod.Post))
{
@Html.HiddenFor(m => m.EventID)
@Html.HiddenFor(m => m.CompanyID)
foreach (var item in Model.Questions)
{
<div class="checkbox">
<input type="checkbox" id="@item.QuestionID" name="QuestionIds" value="@item.Title" />
<label for="@item.QuestionID">@item.Title</label>
</div>
}
<p><input type="submit" class="btn btn-primary" value="Submit" /></p>
}
</code></pre>
<p>Generated HTML looks like:</p>
<pre><code><div class="checkbox">
<input type="checkbox" id="12" name="QuestionIds" value="Would you like an account manager to contact you?" />
<label for="12">Would you like an account manager to contact you?</label>
</div>
<div class="checkbox">
<input type="checkbox" id="13" name="QuestionIds" value="Comments - please be as detailed as possible." />
<label for="13">Comments - please be as detailed as possible.</label>
</div>
</code></pre>
<p>Question collection:</p>
<pre><code>public class Question
{
public Guid QuestionID { get; set; }
public string Title { get; set; }
}
</code></pre>
<p>Controller action</p>
<pre><code> [HttpPost]
public ActionResult Step6(Models.EventCompanyQuestionnaireQuestions model)
{
return View();
}
</code></pre>
<p>The model:</p>
<pre><code>public class EventCompanyQuestionnaireQuestions
{
public int EventID { get; set; }
public int CompanyID { get; set; }
public List<Guid> QuestionIds { get; set; }
}
</code></pre>
<p>When the form is submitted the List is an empty, initialized list. The rendered form element is named QuestionIds which matches the model. I need QuestionIds to have the checked checkboxes.</p>

What does \p{P} mean? : <p>So, I was messing around with regex to convert sentences into pig latin, and decided to extend the assignment to allow for punctuation.
I was looking for a regex that allowed for me to replace the punctuation with an empty string and found <code>myString.replaceAll("\\p{P}", "");</code> and was curious as to what the \p and {P} actually do here. Other similar questions have used <code>"\\p{Z}"</code> to replace whitespace, which leads me to think the \p is searching for whatever is inside of the brackets. Anyways any clarifications or directions to documentation would be much appreciated.</p>

Why is my token being rejected? What is a resource ID? "Invalid token does not contain resource id (oauth2-resource)" : <p>I'm trying to configure OAuth2 for a spring project. I'm using a shared UAA (<a href="https://docs.cloudfoundry.org/api/uaa/version/4.8.0" rel="noreferrer">oauth implementation from cloud foundry</a>) instance my work place provides (so I'm not trying to create an authorization server and the authorization server is separate from the resource server). The frontend is a single-page-application and it gets token directly from the authorization server using the implicit grant. I have the SPA setup where it adds the <code>Authorization: Bearer <TOKEN></code> header on each web API call to microservices.</p>
<p>My issue is now with the microservices.</p>
<p>I'm trying to use this shared authorization server to authenticate the microservices. I might have a misunderstanding here, buy my current understanding is that these microservices play the role of the resource server because they host the endpoints the SPA uses to get data.</p>
<p>So I tried to configure a microservice like so:</p>
<pre><code>@Configuration
@EnableResourceServer
public class OAuth2ResourceServerConfig extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests()
.antMatchers("/api/**").authenticated();
}
@Bean
public TokenStore tokenStore() {
return new JwtTokenStore(accessTokenConverter());
}
@Bean
public JwtAccessTokenConverter accessTokenConverter() {
JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
converter.setVerifierKey("-----BEGIN PUBLIC KEY-----<key omitted>-----END PUBLIC KEY-----");
return converter;
}
@Bean
@Primary
public DefaultTokenServices tokenServices() {
DefaultTokenServices defaultTokenServices = new DefaultTokenServices();
defaultTokenServices.setTokenStore(tokenStore());
return defaultTokenServices;
}
@Override
public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
resources.tokenServices(tokenServices());
}
}
</code></pre>
<p>Now whenever I hit a <code>/api/**</code> with the <code>Authorization: Bearer <TOKEN></code>, I get a <code>403</code> with this error:</p>
<pre><code>{
"error": "access_denied",
"error_description": "Invalid token does not contain resource id (oauth2-resource)"
}
</code></pre>
<hr>
<h2>So here are my questions:</h2>
<ul>
<li><strong>How do I configure these microservices to validate the token and insert a <a href="https://docs.oracle.com/javase/8/docs/api/java/security/Principal.html" rel="noreferrer"><code>Principal</code></a> in controller methods?</strong> I currently have it setup where the SPA has and sends the token and I also have the public key used to verify the signature of the token. I have also used <a href="https://jwt.io/" rel="noreferrer">jwt.io</a> to test the token and it says "Signature Verified".</li>
<li>What is a resource id? Why do I need it and why does it cause the error above? Is that a Spring only thing??</li>
</ul>
<p>Thanks!</p>

Save an array of strings to a string : <p>I have access to one string variable named Storage. I would like to save an array of strings to the Storage variable along with other variables. Is this possible to save an array variable to a string? If it is how do i get the values out of the array? See code I have below.</p>
<pre><code>// This Storage variable is just for code functionality. I do not create it.
string Storage; // See above^
string Apple = "Red";
string Bannana = "Yellow";
Queue<string> myQ = new Queue<string>();
myQ.Enqueue("zero");
myQ.Enqueue("one");
myQ.Enqueue("two");
myQ.Enqueue("three");
string[] myQ_Array = myQ.ToArray();
Storage = Apple + ";" + Bannana + ";" + myQ_Array[0] + ";" + myQ_Array;
var mySplitStorage = Storage.Split(';');
Console.WriteLine("mySplitStorage[0] = " + mySplitStorage[0]);
Console.WriteLine("mySplitStorage[1] = " + mySplitStorage[1]);
Console.WriteLine("mySplitStorage[2] = " + mySplitStorage[2]);//<--This works
Console.WriteLine("mySplitStorage[3] = " + mySplitStorage[3]);//<--Cant get this to work
Console.Read();
// This is the output
//mySplitStorage[0] = Red
//mySplitStorage[1] = Yellow
//mySplitStorage[2] = zero
//mySplitStorage[3] = System.String[] <--- How do i get the values out of the array?

Can someone help me figure out why my mini-max tic-tac-toe AI does not work? : This is me trying to make a minimax tic-tac-toe game. The AI for some reason still goes in order in which the spot turns up on the list for the board. It looks like it is calculating the scores, but I do not think it is utilizing them for some reason. It is supposed to pick the spot with the highest score. It outputs many "You win", "TIE", and "You lose" strings because I wanted to make sure it was iterating through the spaces and combinations. Please help!

Angular2 and TypeScript: error TS2322: Type 'Response' is not assignable to type 'UserStatus' : <p>I'm playing with Angular2 and TypeScript and it's not going well (this would be so easy in AngularJS). I'm writing a little experiment app to get to grips with it all and I have the following component as my main / top level component...</p>
<pre><code>import {Component, OnInit} from 'angular2/core';
import {RouteConfig, ROUTER_DIRECTIVES} from 'angular2/router';
import {UserData} from './services/user-data/UserData';
import {Home} from './components/home/home';
import {UserStatus} from './types/types.ts';
import {Http, Headers, Response} from 'angular2/http';
@Component({
selector: 'app', // <app></app>
providers: [...FORM_PROVIDERS],
directives: [...ROUTER_DIRECTIVES],
template: require('./app.html')
})
@RouteConfig([
{path: '/', component: Home, name: 'Home'},
// more routes here....
])
export class App {
userStatus: UserStatus;
constructor(public http: Http) {
}
ngOnInit() {
// I want to obtain a user Profile as soon as the code is initialised
var headers = new Headers();
headers.append('Content-Type', 'application/json');
this.http.get('/restservice/userstatus', {headers: headers})
.subscribe(
(data: Response) => {
data = JSON.parse(data['_body']);
this.userStatus = data;
},
err => console.log(err), // error
() => console.log('getUserStatus Complete') // complete
);
}
}
</code></pre>
<p>Now when the top level component is bootstrapped / initialised I want to make a call to a phoney REST service (/restservice/userstatus) I set up that returns an object that I have made into a type like so (this is from <code>import {UserStatus} from './types/types.ts'</code>):</p>
<pre><code>export class UserStatus {
constructor (
public appOS?: any , // can be null
public firstName: string,
public formerName?: any, // can be null
public fullPersId: number,
public goldUser: boolean,
public hasProfileImage: boolean,
public hideMoblieNavigationAndFooter: boolean,
public persId: string,
public profileName: string,
public profilePicture: string,
public showAds: boolean,
public siteId: number,
public url: string,
public verified: boolean
) {
}
}
</code></pre>
<p>Now the <code>appOS</code> and <code>formerName</code> properties could potentially be <code>null</code> and when serving up the response in my REST service they are, the JSON object looks like so:</p>
<pre><code>{
appOS: null,
firstName: "Max",
formerName: null,
fullPersId: 123456789,
goldUser: true,
hasProfileImage: true,
hideMoblieNavigationAndFooter: false,
persId: "4RUDIETMD",
profileName: "Max Dietmountaindew",
profilePicture: "http://myurl.com/images/maxdietmountaindew.jpg",
showAds: true,
siteId: 1,
url: "/profile/maxdietmountaindew",
verified: true
}
</code></pre>
<p>So the data structure sent from my phoney service and the Type Object match however when I try to assign the data from the Rest Service to component in the class <code>'this.userStatus = data;'</code> I get the following error.... </p>
<pre><code>"error TS2322: Type 'Response' is not assignable to type 'UserStatus'.
Property 'appOS' is missing in type 'Response'."
</code></pre>
<p>I assume in my Type class I am doing something wrong with the definition where nulls are concerned can anyone see what I am doing wrong or explain why I am getting the error. Thanks in advance.</p>

How to Convert given text into the required date format in SqlServer : <p>I have an old database with a <a href="https://i.stack.imgur.com/bOLl4.png" rel="nofollow noreferrer">table with dateEntered(varchar datatype) column </a> which can take the dates in various formats like <br/>
A> 'wk231216' which means (Week)23-(Date)12-(Year)2016<br/>
B> '231216' which means (Week)23-(Date)12-(Year)2016<br/>
C> 'wk132717' which means (week)13-(Date)27-(year)2017<br/><br/>
Now I need to modify the above dates into this format as 'YYYY-MM-DD'<br/><br/>
A> should become 2016-06-12(wk23 of 2016 is in June(06))<br/>
B> should become 2016-06-12<br/>
C> should become 2017-03-27<br/></p>
<p>Can anyone suggest how to achieve this?

GCS - Read a text file from Google Cloud Storage directly into python : <p>I feel kind of stupid right now. I have been reading numerous documentations and stackoverflow questions but I can't get it right.</p>
<p>I have a file on Google Cloud Storage. It is in a bucket 'test_bucket'. Inside this bucket there is a folder, 'temp_files_folder', which contains two files, one .txt file named 'test.txt' and one .csv file named 'test.csv'. The two files are simply because I try using both but the result is the same either way.</p>
<p>The content in the files is</p>
<pre><code>hej
san
</code></pre>
<p>and I am hoping to read it into python the same way I would do on a local with </p>
<pre><code>textfile = open("/file_path/test.txt", 'r')
times = textfile.read().splitlines()
textfile.close()
print(times)
</code></pre>
<p>which gives</p>
<pre><code>['hej', 'san']
</code></pre>
<p>I have tried using </p>
<pre><code>from google.cloud import storage
client = storage.Client()
bucket = client.get_bucket('test_bucket')
blob = bucket.get_blob('temp_files_folder/test.txt')
print(blob.download_as_string)
</code></pre>
<p>but it gives the output</p>
<pre><code><bound method Blob.download_as_string of <Blob: test_bucket, temp_files_folder/test.txt>>
</code></pre>
<p>How can I get the actual string(s) in the file?</p>

Program to find whether an edge exists between two given vertices of a graph : I wrote the following code in C to find whether there exists an edge between two given vertices of a graph.Initially I ask user for inputs and then check whether there is a edge between two vertices using a BFS approach(queue).
This code is working fine for some testcases but throwing a segmentation fault in few. please tell me where Iam going wrong
#include <stdio.h>
#include <stdlib.h>
int main()

int v,e,e1,e2,t1,t2;
printf("Enter num of vertices and edges: ");
scanf("%d %d",&v,&e);
int maze[v][v];

for(int j=0;j<v;j++)
maze[i][j]=0;
printf("Enter edges:\n")
for(int i=0;i<e;i++)
{
scanf("%d %d",&e1,&e2);
maze[e1-1][e2-1]=1;
maze[e2-1][e1-1]=1;
}
printf("The maze looks like:\n");
for(int i=0;i<v;i++)
{
for(int j=0;j<v;j++)
{
printf("%d ",maze[i][j]);
}
printf("\n");
}
printf("enter target edges: ");
scanf("%d %d",&t1,&t2);
//BFS starts from here.
int queue[v*v];
int k = 1;
queue[0] = t1-1;
for(int i=0;i<v;i++)
if(maze[t1-1][i]==1)
{
queue[k] = i;
k++;
}
int bp,ep;
bp = 0;
ep = k;
while(bp<=ep)
{
if(queue[bp]+1==t2)
{
printf("\nroute exists\n");
exit(0);
}
else

How to dockerize an ASP.NET Core 2.0 application? : <p>I have a simple ASP.NET Core 2.0 application with 2 projects in a solution. One project is a class library (WorldLibrary.dll), which is referenced by the web application (WeatherWeb.dll).</p>
<p>I have tried to follow the steps here:</p>
<p><a href="https://docs.docker.com/engine/examples/dotnetcore/" rel="noreferrer">https://docs.docker.com/engine/examples/dotnetcore/</a></p>
<p>This is my Dockerfile:</p>
<pre><code>FROM microsoft/aspnetcore-build:2.0 AS build-env
WORKDIR /app
# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore
# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out
# Build runtime image
FROM microsoft/aspnetcore:2.0
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "WeatherWeb.dll"]
</code></pre>
<p>But, there is a problem with the referenced .dll. I get the following output from the "docker build" command:</p>
<pre><code>C:\Users\olavt\source\repos\Weather\WeatherWeb>docker build -t weather .

Using webpack with an existing PHP and JS project : <p>I have an existing PHP project with jquery and bootstrap, not using any front-end framework.</p>
<p>I am trying to use webpack module bundler in order to create a single entry point for my project resources, manage js dependencies with node js package manager, run tasks as minify js css, image re-size...etc. And improve the browser loading time required to load a single page.</p>
<p>I came across the webpack tutorials and got to install it and install its dev-server, but the problem is that I am not able to understand how I will convert all my current js scripts and css links in the project (where I have a lot of jquery and CSS libraries used to provide multiple features in the project) to use webpack.</p>
<p><strong>Do I have to rewrite all my JS and CSS files in a way that suits webpack? How do I make a successful migration?</strong></p>
<p><strong>Besides, I am not able to run my current php application on the webpack dev-server, is it meant to run there in the first place? It is only listing the directories of the project in the meantime.</strong></p>
<p>I have created a test <code>index.js</code> file and used the following webpack configuration:</p>
<pre><code>var path = require('path');
var webpack = require('webpack');
module.exports =
{
entry: [
'./public/js/index.js',
'webpack/hot/dev-server',
'webpack-dev-server/client?http://localhost:8080'
],
plugins: [
new webpack.HotModuleReplacementPlugin()
],
output: {
path: path.join(__dirname, "public/dist/js"),
publicPath : "http://localhost:8080/my_proj/public/dist/js",
filename: "bundle.js"
}
};
</code></pre>
<p>I added the <code>bundle.js</code> to my script loads just for testing as follows hoping that the application will run on the webpack dev-server:</p>
<pre><code><script type="text/javascript" src="public/dist/js/bundle.js"></script>
<script type="text/javascript" src="public/js/jquery.min.js"></script>
<script type="text/javascript" src="public/js/jquery.migrate.js"></script>
<script type="text/javascript" src="public/js/jquery.bxslider.min.js"></script>
<script type="text/javascript" src="public/js/jquery.appear.js"></script>
<script type="text/javascript" src="public/js/jquery.countTo.js"></script>
<script type="text/javascript" src="public/js/bootstrap.js"></script>
</code></pre>
<p><strong>Please help me understand the concept here and how can I make this migration successfully?</strong></p>

Keras - Plot training, validation and test set accuracy : <p>I want to plot the output of this simple neural network: </p>
<pre><code>model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
history = model.fit(x_test, y_test, nb_epoch=10, validation_split=0.2, shuffle=True)
model.test_on_batch(x_test, y_test)
model.metrics_names
</code></pre>
<p>I have plotted <em>accuracy</em> and <em>loss</em> of training and validation:</p>
<pre><code>print(history.history.keys())
# "Accuracy"
plt.plot(history.history['acc'])
plt.plot(history.history['val_acc'])
plt.title('model accuracy')
plt.ylabel('accuracy')
plt.xlabel('epoch')
plt.legend(['train', 'validation'], loc='upper left')
plt.show()
# "Loss"
plt.plot(history.history['loss'])
plt.plot(history.history['val_loss'])
plt.title('model loss')
plt.ylabel('loss')
plt.xlabel('epoch')
plt.legend(['train', 'validation'], loc='upper left')
plt.show()
</code></pre>
<p>Now I want to add and plot test set's accuracy from <code>model.test_on_batch(x_test, y_test)</code>, but from <code>model.metrics_names</code> I obtain the same value <em>'acc'</em> utilized for plotting accuracy on training data <code>plt.plot(history.history['acc'])</code>. How could I plot test set's accuracy?</p>

Particles.js as a background? : <p>I'm trying to use this example as a background but I can't seem to get it to work. </p>
<p><a href="http://vincentgarreau.com/particles.js/#nasa" rel="noreferrer">http://vincentgarreau.com/particles.js/#nasa</a></p>
<p>In order to get around this I'm forced to use a margin top of -1500px just to place my text over the top of it and it's causing major issues with responsiveness.</p>
<p>Does anyone have any idea on how I can use it strictly as a background?</p>
<p>The creator of the plugin has done it here on his website. </p>
<p><a href="http://vincentgarreau.com/en" rel="noreferrer">http://vincentgarreau.com/en</a></p>
<p>You can tell because when you inspect it, there is no "canvas" hovering over the top as there is on the CodePen example.</p>

C: Add numbers to filename : I want to store data in different files. Therefore I want to create files as follows: `data_1.log`, `data_2.log`, ..., `data_N.log`. The appendix `.log` is not necessary but would be nice. All my approaches failed so far. Here is one sample that is probably close to what I need:
#include <stdio.h>
#include <string.h>
char get_file_name(int k){
int i, j;
char s1[100] = "logs/data_";
char s2[100];
snprintf(s2, 100, "%d", k);
for(i = 0; s1[i] != '\0'; ++i);
for(j = 0; s2[j] != '\0'; ++j, ++i){
s1[i] = s2[j];
}
s1[i] = '\0';
return s1;
}
int main(){
char file_name[100];
for(int k=0; k<10; k++){
// Get data
// ...
// Create filename
strcpy(file_name, get_file_name(k));
printf("%s", file_name);
fp = fopen(file_name, "w+");
// Write data to file
print_results_to_file();
fclose(fp);
}
return 0;
}
At the moment I get the following errors which I don't understand:
string.c: In function ‘get_file_name’:
string.c:14:12: warning: returning ‘char *’ from a function with return type ‘char’ makes integer from pointer without a cast [-Wint-conversion]

dbeaver: how can I export connection configuration? : <p>I recently got a new macbook pro for work and I'm in the process of migrating a lot of my settings from my old machine. I was hoping that there is a way to export the connection configuration/properties from my old machine rather than have to go through the process of recreating each one. </p>
<p>Does anyone know how to do this? The dbeaver version on my old machine is 6.0.3 and the version on my new machine is 6.1.x</p>

1.I am not familiar with Javascript at all, this is a Java Selenium project (hence why the <code>(JavascriptExecutor)driver).executeScript</code> part and I need to use Javascript for these few lines.<br>

Loop through hosts with ansible : <p>I have a problem to find a working solution to loop over my inventory.
I start my playbook with linking a intentory file:</p>
<blockquote>
<p>ansible-playbook -i inventory/dev.yml playbook.yml</p>
</blockquote>
<p>My playbook looks like this:</p>
<pre><code>---
- hosts: localhost
tasks:
- name: Create VM if enviro == true
include_role:
name: local_vm_creator
when: enviro == 'dev'
</code></pre>
<p>So when loading the playbook the variable enviro is read from host_vars and sets the when condition to dev. The inventory file dev.yml looks like this:</p>
<pre><code>[local_vm]
192.168.99.100
192.168.99.101
192.168.99.102
[local_vm_manager_1]
192.168.99.103
[local_vm_manager_2]
192.168.99.104
[local-all:children]
local_vm
local_vm_manager_1
local_vm_manager_2
</code></pre>
<p>My main.yml in my role local_vm_creator looks like this:</p>
<pre><code>---
- name: Create test host
local_action: shell docker-machine create -d virtualbox {{ item }}
with_items:
- node-1
- node-2
- node-3
- node-4
- node-5
- debug: msg="host is {{item}}"
with_items: groups['local_vm']
</code></pre>
<p>And the problem is that i can't get the listed servers from the dev.yml inventory file.</p>
<p>it just returns: </p>
<blockquote>
<p>ok: [localhost] => (item=groups['local_vm']) => {
"item": "groups['local_vm']",
"msg": "host is groups['local_vm']" }</p>

value of using React.forwardRef vs custom ref prop : <p>I see that React.forwardRef seems to be the sanctioned way of passing a ref to a child functional component, from the react docs:</p>
<pre><code>const FancyButton = React.forwardRef((props, ref) => (
<button ref={ref} className="FancyButton">
{props.children}
</button>
));
// You can now get a ref directly to the DOM button:
const ref = React.createRef();
<FancyButton ref={ref}>Click me!</FancyButton>;
</code></pre>
<p>However, what is the advantage of doing this over simply passing a custom prop?:</p>
<pre><code>const FancyButton = ({ innerRef }) => (
<button ref={innerRef} className="FancyButton">
{props.children}
</button>
));
const ref = React.createRef();
<FancyButton innerRef={ref}>Click me!</FancyButton>;
</code></pre>
<p>The only advantage I can think of is maybe having a consistent api for refs, but is there any other advantage? Does passing a custom prop affect diffing when it comes to rendering and cause additional renders, surely not as the ref is stored as mutable state in the <code>current</code> field?</p>
<p>Say for example you wanted to pass multiple refs (which tbh, might indicate code smell, but still), then the only solution I can see would be to use customRef props.</p>
<p>I guess my question is what is the value of using <code>forwardRef</code> over a custom prop?</p>

The problem seems random and only happens once in a great while. The site may run for months with no issues then out of the blue it will stop serving any .aspx pages and gives the error on every .aspx page request. A restart of the website is the only solution (or redeploy, which causes the same thing).</p>
<p>This was a very difficult problem to debug since it was so sporadic and none of the other answers I found helped, they did not address the problem where the site would deploy and run for long periods of time then crash with this error seemingly randomly.

Testing an IF statement with respect to state with Jest doesn't work : I am trying to test this method which is responsible for editing but am able to the lines which replace the **old title** and the **old body** with the new title and body.
This is located in the IF section. Below is the code which implements editing :
onEditNote = (event) => {
const { target: { value: id } } = event;
const obj = {
title: this.state.title,
body: this.state.body,
};
// clear the errors while submitting
this.setState({ titleError: '', bodyError: '' });
if (obj.title === '') {
this.setState({ titleError: 'Title empty, please add title' });
} else if (obj.body === '') {
this.setState({ bodyError: 'Body empty, please add body' });
} else if (obj.title.length > 20) {
this.setState({ titleError: 'Title is too long.' });
} else {
this.setState((state) => {
const list = state.notesArray.map((item) => {
if (item.id === id) {
// eslint-disable-next-line no-param-reassign
item.title = obj.title;
// eslint-disable-next-line no-param-reassign
item.body = obj.body;
}
return item;
});
localStorage.setItem('items', JSON.stringify(list));
// eslint-disable-next-line no-undef
$('#editModal').modal('close');
this.onSuccessToast('Noted edited successfully.');
return {
list,
title: '',
body: '',
};
});
}
};
These are the lines in the above code which are not covered by the test I implemented :
> if (item.id === id) {
> // eslint-disable-next-line no-param-reassign
> item.title = obj.title;
> // eslint-disable-next-line no-param-reassign
> item.body = obj.body;
> }
And below is my test I am implementing which doesn't cover the IF statement, yet I see I have covered it :
it('should edit a Note.', () => {
wrapper = shallow(<App />);
$.fn.modal = jest.fn();
wrapper.instance().onEditNote({ target: { value: '0' } });
wrapper.instance().setState({

I have it going in a complete loop and don't kn ow how to make it stop : my teacher asked us to create a magic 8 ball program in java 8. we have to use 3 methods, a main, a processing, and an output and we need to pass parameters between the methods. the output needs to use the switch statement, we need to have a while statement in there and the answers need to be randomly generated. I have everything required but when I try to run the program it is stuck in the while loop and I don't know what I did wrong.
here is what I have:
import java.util.*;
public class Magic8Ball {
public static void main(String[]args) {
Scanner input = new Scanner(System.in);
System.out.print("Would you like to ask a question? Y or N: ");
char answer = input.next().charAt(0);
char Y = Character.toUpperCase(answer);
process(answer, Y);
}
public static void process(char a, char Yes) {
if (a != Yes) {
System.out.println("Thank you, goodbye.");
}
else {
while(a==Yes) {
System.out.print("Ask your question: ");
Random random = new Random();
int ran = random.nextInt(8-1+1)+1;
output(ran);
}
}
}
Public static int output(int r) {
switch (r) {
case 1: System.out.println("Out of memory, try again later); break;
case 2: System.out.println("The probability matrix supports you."); break;
case 3: System.out.println("That does not compute."); break;
case 4: System.out.println("System error, try again later"); break;
case 5: System.out.println("Siri says yes."); break;
case 6: System.out.println("The asnwer could not be found on the internet."); break;
case 7: System.out.println("Wikilinks claims it is true."); break;
case 8: System.out.println("Siri says no."); break;
default: System.out.println("The system is not responding, try again later"); break;
}
return r;

Scale just part of a curve - python sciPy : I need to scale a curve as shown on the picture underneath. The curve is a two-dimensional array consisting of many X and Y values. It is important that the curve stays continuous and there is no "leap" at the place where I want to cut. Do you have any ideas? Is there a function/functions in python that can do this?

UITextField secureTextEntry toggle set incorrect font : <p>I have an <code>UITextField</code> which I use as a password field. It has by default <code>secureTextEntry</code> set to <code>true</code>.
I also have a <code>UIButton</code> to toggle the show/hide of the password.</p>
<p>When I change the textfield from <code>secureTextEntry</code> set to <code>true</code> to <code>false</code>, the font gets weird. Seems it becomes Times New Roman or similar.</p>
<p>I have tried re-setting the font to system with size 14, but it didn't change anything. </p>
<p>Example of what happens (with initial <code>secureTextEntry</code> set to <code>true</code>):
<a href="https://i.stack.imgur.com/ab5sy.gif" rel="noreferrer"><img src="https://i.stack.imgur.com/ab5sy.gif" alt="Example"></a></p>
<p>My code:</p>
<pre><code>@IBAction func showHidePwd(sender: AnyObject) {
textfieldPassword.secureTextEntry = !textfieldPassword.secureTextEntry
// Workaround for dot+whitespace problem
if !textfieldPassword.secureTextEntry {
let tempString = textfieldPassword.text
textfieldPassword.text = nil
textfieldPassword.text = tempString
}
textfieldPassword.font = UIFont.systemFontOfSize(14)
if textfieldPassword.secureTextEntry {
showHideButton.setImage(UIImage(named: "EyeClosed"), forState: .Normal)
} else {
showHideButton.setImage(UIImage(named: "EyeOpen"), forState: .Normal)

What are the pros and cons of using AWS CodePipeline vs Jenkins : <p>What are the pros and cons of using AWS CodePipeline vs Jenkins?</p>
<p>I can't see a whole lot of info on the interwebs (apart from <a href="https://stackshare.io/stackups/jenkins-vs-aws-codepipeline" rel="noreferrer">https://stackshare.io/stackups/jenkins-vs-aws-codepipeline</a>). As far as I can see they are as follows:</p>
<p>AWS CodePipeline Pros</p>
<ul>
<li>Web-based </li>
<li>integrated with AWS</li>
<li>simple to setup (as web-based)</li>
</ul>
<p>AWS CodePipeline Cons</p>
<ul>
<li>can't be used to set up code repos locally</li>
</ul>
<p>Jenkins Pros</p>
<ul>
<li>standalone software</li>
<li>can be used for many systems (other than AWS)</li>
<li>many options for setup (e.g. plugins)</li>
<li>can be used to setup code repos locally </li>
</ul>
<p>Any other major differences that people can use to make an informed choice?</p>

<li>Mathematical Functions </li>
<li>Characters</li>
<li>Strings </li>
<li>Loops</li>
<li>Methods</li>

<p>I'm still learning Java so this is sort of intimidating given the timeline that I have from today until next Wednesday (3-29-17.)</p>
<p>Could someone give me insight to how you break down the learning of new material in a short amount of time? </p>

Why is std::less better than "<"? : <p>C++ primer, 5th, 14.8.2, Using a Library Function Object with the Algorithms:</p>
<pre><code>vector<string *> nameTable; // vector of pointers
// error: the pointers in nameTable are unrelated, so < is undefined
sort(nameTable.begin(), nameTable.end(),
[](string *a, string *b) { return a < b; });
// ok: library guarantees that less on pointer types is well defined
sort(nameTable.begin(), nameTable.end(), less<string*>());
</code></pre>
<p>Then I checked the std::less implementation:</p>
<pre><code>template<typename _Tp>
struct less : public binary_function<_Tp, _Tp, bool>
{
bool
operator()(const _Tp& __x, const _Tp& __y) const
{ return __x < __y; }
};
</code></pre>
<p>I found out that std::less also use operator < to do the work, so why < is undefined and library guarantees that less on pointer types is well defined, why is std:less recommended, and why is std::less better than <.</p>
