Mysterious Http 408 errors in AWS elasticbeanstalk-access_log : <p>The elasticbeanstalk-access_log log-file in our AWS EBS instances are full of 408 errors, like these:</p>

172.31.1.56 (-) - - [16/Mar/2016:10:16:31 +0000] "-" 408 - "-" "-"

172.31.1.56 (-) - - [16/Mar/2016:10:16:31 +0000] "-" 408 - "-" "-"
172.31.1.56 (-) - - [16/Mar/2016:10:16:59 +0000] "-" 408 - "-" "-"
</code></pre>
<p>They appear randomly, sometimes there are a few minutes between them, sometimes there are 4-6 errors within a few seconds. These errors also happen on our non-public staging environment when there is no any real traffic on the server, so the source of these requests is probably one of AWS's own service.</p>

How could I make a calendar? : <p>I'm trying to make a calendar for a client's website. I was wondering how should I go about doing this. I want it to when someone taps on a day it would show a modal with a form for that day. This form would then submit a scheduled appointment for that day. I assume I could use JavaScript or PHP to change the days for the appropriate month and year. </p>
<p>A good example of this is in windows 10 you have a calendar that lets you click on a day and you can set up an agenda or something. If anyone could point me in the direction of how I could start this please let me know. Thanks! </p>

Java 8 - add property of object to list : <p>I have an empty list of integers:</p>
<pre><code>final List<Integer> reservedMarkers = new ArrayList<>();

<p>and I will fill this list with the marker property of a list of objects, such like this:</p>
<pre><code>scheduleIntervalContainers.stream().forEach(s -> s.getMarker(), reservedMarkers.add(s));
</code></pre>
<p>My final target would be to get the highest marker number but actually I dont know a better way as getting all marker numbers, than sort it and than get the highest one.</p>
<p>this does not work for sure, is there a possibility to do this in this way?</p>

Should I use ref or findDOMNode to get react root dom node of an element? : <p>I'm on a situation where I want to make some dom-node size calculations (top, bottom and size properties of the rendered DOM node)</p>
<p>What I'm doing right now, on the <code>componentDidUpdate</code> method is to call findDOMNode on this:</p>
<pre><code> componentDidUpdate() {
var node = ReactDOM.findDOMNode(this);
this.elementBox = node.getBoundingClientRect();
this.elementHeight = node.clientHeight;
// Make calculations and stuff
}
</code></pre>
<p>This is working fine, but I'm a bit worried about performance, and react best practices. Several places talks about using <code>ref</code> property instead of findDOMNode, but all of them are for child dom elements, on my case I only want the root DOM node of my component. </p>
<p>The alternative using ref may look like this:</p>
<pre><code>render(){
return (
<section // container
ref={(n) => this.node = n}>
// Stuff
</section>
}
componentDidUpdate() {
this.elementBox = this.node.getBoundingClientRect();
this.elementHeight = this.node.clientHeight;
// Make calculations and stuff
}
</code></pre>
<p>To be honest, attaching a ref callback to my root dom node just to get it's reference does not feel correct to me.</p>
<p>What is considered the best practice on this case ? Which one has better performance ?</p>

Convert java.util.Date to what “java.time” type? : <p>I have a <a href="http://docs.oracle.com/javase/8/docs/api/java/util/Date.html" rel="noreferrer"><code>java.util.Date</code></a> object, or a <code>java.util.Calendar</code> object. How do I convert that to the right type in <a href="http://docs.oracle.com/javase/8/docs/api/java/time/package-summary.html" rel="noreferrer">java.time</a> framework? </p>
<p>I have heard that we should now be doing the bulk of our business logic with java.time types. When working with old code not yet updated for java.time I need to be able to convert back and forth. What types map to <code>java.util.Date</code> or <code>java.util.Calendar</code>?</p>

Using spring embedded ldap to simulate active directory for integration tests : <p>I am using the Spring Security <code>ActiveDirectoryLdapAuthenticationProvider</code> with Spring Boot (annotation based config) to authenticate with Active Directory and generate tokens. All works fine. </p>
<p>I wish to add some integration tests that simulate the whole process, and I was thinking of maybe using the Spring embedded LDAP server for that.</p>
<p>I added this ldif file that I got from another example I found online. </p>
<pre><code>#Actual test data
dn: dc=test,dc=com
objectclass: top
objectclass: domain
objectclass: extensibleObject
dc: local
# Organizational Units
dn: ou=groups,dc=test,dc=com
objectclass: top
objectclass: organizationalUnit
ou: groups
dn: ou=people,dc=test,dc=com
objectclass: top
objectclass: organizationalUnit
ou: people
# Create People
dn: uid=testuser,ou=people,dc=test,dc=com
objectclass: top
objectclass: person
objectclass: organizationalPerson
objectclass: inetOrgPerson
cn: Test
sn: User
uid: testuser
password: secret
# Create Groups
dn: cn=developers,ou=groups,dc=test,dc=com
objectclass: top
objectclass: groupOfUniqueNames
cn: developers
ou: developer
uniqueMember: uid=testuser,ou=people,dc=test,dc=com
dn: cn=managers,ou=groups,dc=test,dc=com
objectclass: top
objectclass: groupOfUniqueNames
cn: managers
ou: manager
uniqueMember: uid=testuser,ou=people,dc=test,dc=com
</code></pre>
<p>But this of course does not include any of the Active Directory schema stuff.
Each user needs to have a <code>sAMAccountName</code> and needs to have the <code>memberOf</code> attribute to determine which groups it is in.</p>
<p>Is there any way to make this behave similar to active directory so that the Spring <code>ActiveDirectoryLdapAuthenticationProvider</code> binds to it with the user's username and password and gets its group membership to populate its authorities?</p>
<p>Otherwise if this is not viable, is there any other way to mock this and have a proper test?</p>

Lisp finding all even numbers and adding them to new list : <p>Given a list (3 b 6 7 8), I'm trying to find all the even numbers and add them to a new list and then print this list.
I am using a do loop to cdr through my list. Then using (if (evenp (car mylist))) and now I want to save the first even number onto a new list and then restart the if statement. The final print should be (6 8).</p>

Is there a simple way to convert a list of integers to a formatted string in Python? : <p>I am writing a program which generates a list of integers, for example:</p>
<pre><code>[2, 5, 6, 7, 8, 9, 10, 15, 18, 19, 20]
</code></pre>
<p>This list can be very long, but it contains many consecutive values, as seen in this example. </p>
<p>In order to store it (in a database), I would like to convert it to a formatted string, in the following format:</p>
<pre><code>"2,5-10,15,18-20"
</code></pre>
<p>I already have in mind a solution, which is iterating through the whole list to detect consecutive values and building the string.</p>
<p>My question is: is there another, simpler way of doing this conversion in Python?</p>

Calculate average based on condition in r : I have a table
Country ClaimId ClaimItem ClaimAmt
IN C1 1 100
IN C1 2 200
US C2 1 100
US C2 2 100
US C2 3 100

US C3 2 100
UK C4 1 100
UK C4 2 200
UK C1 1 100
UK C1 2 200
Here I want to calculate average per claimID such that my expected table looks like
Country ClaimId ClaimItem ClaimAmt Avg
IN C1 1 100 300
IN C1 2 200 300
US C2 1 100 250
US C2 2 100 250

UK C4 1 100 300
UK C4 2 200 300
UK C1 1 100 300
UK C1 2 200 300
Any idea on how the expected table can be achieved.

Using this and super() in java : <p>I am wanting to know what <code>this</code> and <code>super</code> do in the following code. I know that <code>this</code> refers to the current object and <code>super</code> is used to invoke overridden methods as well invoke a superclasses constructor. But I just can't figure out what the following code does when class <code>C</code> is executed.</p>
<pre><code>public class A {
public A(int id) {
super();
this.id = id;
System.out.println("A created");
}
private int id = 0;
@Override protected void finalize() throws Throwable {
System.out.println("A finalised");
super.finalize();
}
}
public class B extends A {
public B(int id) {
super(id);
System.out.println("B created");
}
public B() {
this(42);
System.out.println("B created with default id 42");
}
@Override protected void finalize() throws Throwable {
System.out.println("B finalised");
super.finalize();
}
}
public class C {
public static void main(String[] args) throws Exception{
new B();
System.gc();
Thread.sleep(1000);
}
}
</code></pre>
<p>I am referring mainly to <code>this(42)</code>, <code>super(id)</code> and <code>super.finalize()</code>in class <code>B</code></p>
<p>-Does <code>this(42)</code> mean that <code>B</code> is instantiated with the value 42, as well as setting <code>A</code> id to 42?</p>
<p>-Does <code>super(id)</code> pass whatever value that <code>B</code> is instantiated with to its superclass which is <code>A</code> ? effectively setting the value of <code>id</code> in <code>A</code> to 42?</p>
<p>-Does <code>super.finalize()</code> call the garbage collector on to superclass <code>A</code> ?</p>

How can a const expr be evaluated so fast : <p>I have been trying out const expressions which are evaluated at compile time.
But I played with an example that seems incredibly fast when executed at compile time.</p>
<pre><code>#include<iostream>
constexpr long int fib(int n) {
return (n <= 1)? n : fib(n-1) + fib(n-2);
}
int main () {
long int res = fib(45);
std::cout << res;
return 0;
}
</code></pre>
<p>When I run this code it takes about 7 seconds to run. So far so good. But when I change <code>long int res = fib(45)</code> to <code>const long int res = fib(45)</code> it takes not even a second.
To my understanding it is evaluated at compile time.
<strong>But the compilation takes about 0.3 seconds</strong></p>
<p>How can the compiler evaluate this so quickly, but at runtime it takes so much more time?
I'm using gcc 5.4.0.</p>

Where should I save created files? : <p>I need to save users created pdf files somewhere. I wanted to save files to ClassPathResource (but I read that It is not a good idea), because I need one thing... Application must work on every computer... so I cannot save it directly on my disc...
Any recommendation, where I could save pdf files to make it work as I need?</p>

Generating an evenly sized matrix by a given number in python? : I have a python list containing `n` items. I would like to place the items in an (nearly) evenly sized matrix.
I mean, if number of elements is 2, then matrix size would be 1*1,
number of items 4, matrix size: 2*2
number of items 5, matrix size: 3*2
number of items 6, matrix size: 3*2
number of items 7, matrix size: 3*3
I hope you understood the problem.

VueJS v-if = array[index] is not working : <p>I wanted to make a component which gets text-box when mouse is over the image.</p>
<p>Below is HTML template.</p>
<pre><code><section class="item-container" v-for="(item, index) in items">
<div class="image-box" @mouseenter="changeStatus(index)">
<img class="image" src="item.link" alt>
</div>
<div class="text-box" @mouseleave="changeStatus(index)" v-if="show[index]">
<h4>{{ item.name }}</h4>
<p>{{ item.content }}</p>
</div>
</section>
</code></pre>
<p>And below is app.js</p>
<pre><code>new Vue({
el: '#app',
data: {
show: [false, false, false],
items: [
{
name: 'Author 1',
content: 'Content 1'
},
{
name: 'Author 2',
content: 'Content 2'

{

changeStatus: function(index) {
this.show[index] = !this.show[index];
console.log(this.show);
console.log(this.show[index]); // console gets it as expected
}
}
});
</code></pre>
<p>When I execute above codes, I can find that the show property has changed. However, v-if is not updated. Can't we use array[index] for v-if or is there other reason for it?</p>

Macro to generate several instances by editing the master copy : https://www.dropbox.com/s/v4zpig6i58...pture.JPG?dl=0
Above is a screenshot of what I would like to change. In the picture the ### needs to be replaced by
N01
N02
N10 etc this will be specified as required because it wont be in an order (can be N01, N05, N12 etc) and the rest needs to be copy pasted. This needs to be generated in a new worksheet.
The newly generated worksheet will have all the instances of N01, N02 etc populated together. Screenshot of the required result is given below

Hide website from users browser history : <p>I am about to begin work on an information and support services website for victims of domestic and sexual abuse. Naturally, the user's visit to this website is sensitive and the repercussions of their abuser finding out that they have could be devastating. Therefore, I am seeking a way to keep the user's visit as discreet as possible.</p>
<p>I cannot assume the technical knowledge of each user and there are likely to be users of a wide variety of languages. Also, there is the possibility they will need to exit the site quickly (I have the solution for this) and perhaps may not be able to return to the computer before being discovered. So, while the most obvious solution is to have a page educating users on how to clear their browsing history - this may not be the most foolproof method in practice. Because of all the variables in play, a blanket solution would be the best solution.</p>
<p>So far, I can think of two solutions to this but am hitting a wall with both:</p>
<p>Firstly, simply not have the website recorded in the browsers' search history. From what I have read this is going to be problematic between browsers if not impossible to implement. </p>
<p>The second would be to have a landing page at an innocuous domain name that wouldn't draw suspicion and then have a button that automatically loaded the website through a Private or Incognito browser (I could simply write instructions, 'Right Click on the Button and Select 'Open in an Incognito Browser' - but I am searching for a more foolproof solution if possible).</p>
<p>While some incarnation of the second solution seems more plausible - I need to consider that abusers searching through browser history is a possibility and therefore, the first solution is the most desirable.</p>
<p>Any ideas on either of these two methods or anything more ideas you have would be most welcomed.</p>

ViewModelFactory provideViewModelFactory(Repository repository, VideoDataSourceFactory videoDataSourceFactory) {
...
}
</code></pre>
<p>Now, I need to do the same thing, however my call needs a new parameter: an id. </p>
<pre><code>@GET(Urls.VIDEOS_BY_CATEGORY)
Observable<RequestVideo> getVideosByCategory(
@Path("id") int categoryId, // <-- Now I need this new parameter
@Query("per-page") int perPage,
@Query("page") int page);
</code></pre>
<p>Before, my PageKeyedVideosDataSource needed only the page and the per-page to make the call, it was easy. However, now I need to put this new parameter id dynamically inside the PageKeyedDataSource.</p>
<p>I saw <a href="https://github.com/googlesamples/android-architecture-components/tree/master/PagingWithNetworkSample" rel="noreferrer">PagingWithNetworkSample</a> and figured it out that they put a new parameter in PagedKeyedDataSource by adding it in the constructor. Then, I thought about doing this:</p>
<pre><code>public PageKeyedCategoryVideosDataSource(int categoryId, Repository repository) {
this.categoryId = categoryId;
this.repository = repository;
}
</code></pre>
<p>However, if I add the id in the constructor, I think I'll not be able to use dagger 2 anymore because by using dagger 2 the PageKeyedVideosDataSource is not created dynamically, therefore, I can't keep changing the value of the id.</p>
<p>I need to create the PageKeyedDataSource dynamically like this:</p>
<pre><code>int categoryId = getCategoryId();
PageKeyedVideosDataSource dataSource = new PageKeyedVideosDataSource(categoryId, repository);
</code></pre>
<ul>
<li>Should I do this and not use Dagger 2?</li>
<li>Is it possible to dynamically create the DataSource still using Dagger 2?</li>
</ul>

Find if word exist in array or string PHP : <p>I am trying to find if any of the string inside an array exist in array of words.</p>
<p>For example:</p>
<pre><code>$key = ["sun","clouds"];
$results = ["Sun is hot","Too many clouds"];
</code></pre>
<p>If any of <code>$key</code> exists in <code>$results</code> to return <code>true</code></p>
<p>With below script I get the result I want but only if word in <code>$results</code> is exact like the word in <code>$key</code>.</p>
<pre><code>function contain($key = [], $results){
$record_found = false;
if(is_array($results)){
// Loop through array
foreach ($results as $result) {
$found = preg_match_all("/\b(?:" .join($key, '|'). ")\b/i", $result, $matches);
if ($found) {
$record_found = true;
}
}
} else {
// Scan string to find word
$found = preg_match_all("/\b(?:" .join($key, '|'). ")\b/i", $results, $matches);
if ($found) {
$record_found = true;
}
}
return $record_found;
}
</code></pre>
<p>If the word in <code>$results</code> is <code>Enjoy all year round **sunshine**</code> my function returns <code>false</code> as can not find word sun. How can I change my function to return true if string contain that string as part of word?</p>
<p>I want the word <code>sun</code> to match even with <code>sun</code> or <code>sunshine</code>.</p>
<p>TIA</p>

How does string works in c#? : <p>I know strings are inmutable, once created we cannot change it, I've read that if we create a new string object and we assign a value to it and then we assign another value to the same string object internally there is actually another object created and assigned with the new value. Let's say I have:</p>
<pre><code>string str = "dog";
str = "cat";
</code></pre>
<p>If I write <code>Console.WriteLine(str);</code> it returns <code>cat</code>.
So internally there are two objects? But they have the same name? How does it works? I've made some research on google but I have not find yet something convincing enough to me so I can clarify my thoughts about this.
I know strings are reference types, so we have an object in the stack with a reference to a value in the heap, what's happening in this case?(see code above).</p>
<p>I've upload a picture, apologize me if I'm wrong about the idea of the stack and the heap that's why I'm asking this question.
Does the picture reflects what happens in the first line of code(<code>string str = "dog";</code>)? And then what should happen in the second line of code?? The <code>dog</code> value in the heap changes? And then a new object in the stack is created referencing it? Then what happens with the object that was there before? Do they have the same name?
I'm sorry for so many questions but I think that is very important to understand this correctly and to know what's happening behind the scenes...<a href="https://i.stack.imgur.com/3laO8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3laO8.png" alt="enter image description here"></a></p>

if this is wrong way, then tell me how to do it.

<pre><code> names: [{ name: string }] = [{ name: 'Tom' }, { name: 'Dave' }, { name: 'Katie' }, { name: 'John' }];

Changing state without changing browser history in angular ui-router : <p>Assume that we have a logic like this:</p>
<ul>
<li>From state A, change to state B.</li>
<li>Whenever we arrive to state B, the app always redirect us to state C by calling <code>$state.go(stateC)</code></li>
<li>Now we are in state C</li>
</ul>
<p>My question is how to go back to state A from state C (given the fact that state A can be any state we don't know at run-time, meaning user can access state B from any other states)</p>

Vue.js scroll to top of page for same route : <p>I can set scrolling behaviour to Vue.js Router like this:</p>
<pre><code>const router = new Router({
mode: 'history',
routes: [
{
path: '/',
name: 'index',
component: Main
},
{
path: '/some-path',
name: 'some-path',
component: SomePath
}
],
scrollBehavior() {
return {x: 0, y: 0}
}
})
</code></pre>
<p>This works perfectly when you click on the link with some page which is not current. When I click on the link which is already rendered, i.e. in the footer, nothing happens. Vue Router assumes there is no state transition. What is the preferred way to scroll up in this case?</p>

(red and green button maybe ) How ı can do it exactly? Since the servers belong to us, I want the commands to work correctly. What exactly do I want to show on the screen if Ping is successful?</p>

How to resolve external packages with spark-shell when behind a corporate proxy? : <p>I would like to run spark-shell with a external package behind a corporate proxy. Unfortunately external packages passed via <code>--packages</code> option are not resolved.</p>
<p>E.g., when running</p>
<pre><code>bin/spark-shell --packages datastax:spark-cassandra-connector:1.5.0-s_2.10
</code></pre>
<p>the cassandra connector package is not resolved (stuck at last line):</p>
<pre><code>Ivy Default Cache set to: /root/.ivy2/cache
The jars for the packages stored in: /root/.ivy2/jars
:: loading settings :: url = jar:file:/opt/spark/lib/spark-assembly-1.6.1-hadoop2.6.0.jar!/org/apache/ivy/core/settings/ivysettings.xml
datastax#spark-cassandra-connector added as a dependency
:: resolving dependencies :: org.apache.spark#spark-submit-parent;1.0
confs: [default]
</code></pre>
<p>After some time the connection times out containing error messages like this:</p>
<pre><code>:::: ERRORS
Server access error at url https://repo1.maven.org/maven2/datastax/spark-cassandra-connector/1.5.0-s_2.10/spark-cassandra-connector-1.5.0-s_2.10.pom (java.net.ConnectException: Connection timed out)
</code></pre>
<p>When i deactivate the VPN with the corporate proxy the package gets resolved and downloaded immediately.</p>
<p>What i tried so far:</p>
<p>Exposing proxies as environment variables:</p>
<pre><code>export http_proxy=<proxyHost>:<proxyPort>
export https_proxy=<proxyHost>:<proxyPort>
export JAVA_OPTS="-Dhttp.proxyHost=<proxyHost> -Dhttp.proxyPort=<proxyPort>"
export ANT_OPTS="-Dhttp.proxyHost=<proxyHost> -Dhttp.proxyPort=<proxyPort>"
</code></pre>
<p>Running spark-shell with extra java options:</p>
<pre><code>bin/spark-shell --conf "spark.driver.extraJavaOptions=-Dhttp.proxyHost=<proxyHost> -Dhttp.proxyPort=<proxyPort>" --conf "spark.executor.extraJavaOptions=-Dhttp.proxyHost=<proxyHost> -Dhttp.proxyPort=<proxyPort>" --packages datastax:spark-cassandra-connector:1.6.0-M1-s_2.10
