Differences between Visual Studio Build step and MSBuild Build step : <p>I'm creating some build definitions and the only difference I see between the Visual Studio Build Step and MSBuild Build Step is that the VS Build Step adds the visual studio version to the build. </p>
<p>Somebody can explain maybe more differences?</p>

Keycloak behind apache reverse proxy : <p>I have surfed through google without finding any <strong>concrete</strong> answers or <strong>examples</strong>, so again trying my luck here (often get lucky).</p>
<p><strong>The problem</strong></p>
<ul>
<li><p>I have a single spring boot RESTful service running behind an apache
reverse proxy. This RESTful service is running HTTP only. Say it's running on
local ip 172.s port 8080.</p></li>
<li><p>I have also configured an apache reverse proxy. Say it's running on
local ip 172.a and public ip 55.a. This proxy responds to both port 80, but all the HTTP traffic is automatically redirected to 443.</p></li>
<li><p>I have another server running a standalone Keycloak server. Also
this server is configured to be public accessible through the
reverse proxy. Say it's running on local ip 172.k. This Keycloak server is running on HTTP-only. The HTTP requests are handled using SSL over the reverse proxy.</p></li>
<li><p>Last, I have another frontend-webapp running on local ip 172.f. This frontend-webapp is running under Nodejs, and is also configured through the reverse proxy. It's also running only HTTP, but client(browser) is using SSL through the reverse proxy, just as for the Keycloak and RESTful service. This frontend is consuming the RESTful service, and is also configured to authenticate using the keycloak javascript adapter.</p></li>
<li><p>The RESTful service is configured as bearer-only using Spring Boot Keycloak adapter, while the frontend app is configured with access type public.</p></li>
</ul>
<p>The RESTful service server, Keycloak server, and the frontend server are not public accessible; they are accessible only through the reverse proxy. But they can communicate with each other (since they are in the same private network).</p>
<p>In the frontend keycloak.json file, the <code>auth-server-url</code> is set to the proxy url <code>https://example.com/auth</code>, and the frontend is able to successfully get a valid token. Now when I try to consume the RESTful service, I get a error in RESTful adapter that the token issuer is invalid. In the http-header I am, of course, sending the <code>Authorization: Bearer <token></code>. The reason I am getting this error is that in RESTful keycloak configuation, I have configured the <code>auth-server-url</code> to use the local url <code>http://172.k:9080/auth</code>, so this url is different from the one in the token (which is <code>https://example.com/auth</code>).</p>
<p><strong>Question</strong></p>
<p>I cannot include the same <code>auth-server-url</code> in the RESTful service as for the frontend, because that will require me to also setup HTTPs on the RESTful service (because that url is https), and that will complicate stuff a lot, including the need to setup certificates and stuff like that. Also I think it's inefficient and not practical to setup SSL on local only servers.</p>
<p>So my question is how I can make the adapter talk to the Keycloak without going through the reverse proxy. I want the RESTful adapter to talk to the Keyclok server for token verification through <code>auth-server-url: http://172.k:9080/auth</code>.</p>
<p>Earlier there was a different url for backend, that got removed: <a href="https://issues.jboss.org/browse/KEYCLOAK-2623" rel="noreferrer">https://issues.jboss.org/browse/KEYCLOAK-2623</a></p>

React.js - Can't read property of undefined : <p>I'm making very simple react app. Yet as I try to invoke method of parent (actually grandparent) component via onChange event, I keep getting <code>Uncaught TypeError: Cannot read property 'props' of undefined</code>.</p>
<p>Here is the component/form that is triggering the event (thus invoking method on binded parent component... Yes I used .bound(this) on the method as I passed it down from parent component via props.).</p>
<pre><code>class MonthsTable extends Component {
handleChangeOnMonth(e){
this.props.setMonth(e.target.id, e.target.value); // here the method is not found, causing error.
}
render(){
console.log(this.props.setMonth) // here the method is present alright
return (<form>
{this.props.months.map((e, i) =>
<input
type='number'
id={i}
key={i} // yes I know, bad habit, but in this case it doesn't matter
value={this.props.months[i]}
onChange={this.handleChangeOnMonth} />)}
</form>)
}
}
</code></pre>
<p>Here is how I pass the method as props from most parent (grandparent) component.</p>
<pre><code><Months setMonth={this.setMonth.bind(this)} />
</code></pre>
<p>Here is how I pass the method as props in the parent (the component that is between method owner and method invoker)</p>
<pre><code><MonthsTable setMonth={this.props.setMonth} />
</code></pre>
<p>And finally passed to component (MonthsTable) that you saw first. Wheter it is relevant or not, final (most child) components is displayed depending of if statement which works just fine (Might somehow be relevant, I don't know).</p>
<p>Question is... Why is the (setMonth) method 'invisible' inside of (handleChangeOnMonth) method.</p>
<p>Thanks for any advice. </p>

Math.random starts to generate negatives while shouldn't : I have an issue with Math.random(); I've made an AI for game "Guessing number game" and it works just fine until the Player hit number **lower** than searched number. After that Math.random(); **may** and it is very likely to generate negative numbers. If player hit the number lower than searched number. (Range of numbers gessing by AI is defined by two nums (the highest from array of nums **lower[];** than searched and lowest from array **higher[];** than searched). Here is whole code on GitHub since its too large to put it in here and i really don't know where issue can be located: https://github.com/lkobylanski/Guessing-number-game-1P-AI/blob/master/PvAv1.2.js
Function starts to generate negatvies during executting this part of code:
else if(higher_l > 0 && lower_l > 0)
{ //losuje od 0 (ZERA) do (max-min+1) i dodaje + min;
guessed = Math.floor(Math.random()*((higher[0])-((lower[0]+1)+1))+(lower[0]+1));
if(guessed > drawn)
{
c2--;
document.getElementById("notes2").innerHTML = p2 + " remaining chances: " + c2;
higher.push(guessed);
higher_l = higher.length;
higher.sort(function(a, b) {return a-b;});
resultH = resultH + guessed + " ";
document.getElementById("higher").innerHTML = "Proper number is lower than: " + resultH;
counter = setTimeout(checkCounters, 100);
switch_trigger = setTimeout(switchPlayers, 2000);
return;
}
else if(guessed < drawn)
{

document.getElementById("notes2").innerHTML = p2 + " remaining chances: " + c2;
lower.push(guessed);
lower_l = lower.length;
lower.sort(function(a, b) {return b-a});
resultL = resultL + guessed+ " ";
document.getElementById("lower").innerHTML = "Proper number is higher than: " + resultL;
counter = setTimeout(checkCounters, 100);

return;
}
else if(guessed == drawn)
{
p2w++;
document.getElementById("all_wins").innerHTML = p1 + " wins: " + p1w + "/" + wins + "<br/>" + p2 + " wins " + p2w + "/" + wins;
if(p2w < wins)
{
document.getElementById("msg").innerHTML = "AI found the number: " + guessed + "first!<br/>" + currentp + " and gets a point!";
document.getElementById("next").disabled = false;
}
else if(p2w == wins)
{
alert("Winner is " + currentp + "!");
document.getElementById("msg").innerHTML = "AI found the number: " + guessed + " <br/> Player: " + currentp + " reached required number of: " + wins + " wins first!";
}
end = setTimeout(endMatch, 100);
return;

I know that the code itself could be a way better than this but i want to improve it when the whole thing will be working. I'll be very greatful for any help.

Could you explain the solution to front_back google python exercise : <p>I am looking for an explanation to the solution to the front_back google python exercise. Specifically, I do not understand why the % symbol (placeholder?) is used. I also do not understand why the length of the strings are divided by 2. Especially since 2 does not equal 1 (2==1??)</p>
<p>The problem/solution is as follows:</p>
<pre><code># F. front_back
# Consider dividing a string into two halves.
# If the length is even, the front and back halves are the same length.
# If the length is odd, we'll say that the extra char goes in the front half.
# e.g. 'abcde', the front half is 'abc', the back half 'de'.
# Given 2 strings, a and b, return a string of the form
# a-front + b-front + a-back + b-back
def front_back(a, b):
# +++your code here+++
# LAB(begin solution)
# Figure out the middle position of each string.
a_middle = len(a) / 2
b_middle = len(b) / 2
if len(a) % 2 == 1: # add 1 if length is odd
a_middle = a_middle + 1
if len(b) % 2 == 1:
b_middle = b_middle + 1
return a[:a_middle] + b[:b_middle] + a[a_middle:] + b[b_middle:]
# LAB(replace solution)
# return
# LAB(end solution)

Download pdf file inside WebView using AdvancedWebview : I'm struggling a lot on getting to download files inside an webView when link is clicked within it. I searched many forums and mostly they work when I run application in Bluestacks emulater but when I installed it in device, only Downloading file appears and nothing happens after that.
Then I came across Advancced webView but I have no clue what to write inside if and else statement to get what I desires
Here is the code from library to initiate download
public void onDownloadRequested(String url, String suggestedFilename, String mimeType, long contentLength, String contentDisposition, String userAgent) {
// some file is available for download
// either handle the download yourself or use the code below
if (AdvancedWebView.handleDownload(this, url, suggestedFilename)) {
// download successfully handled
}
else {
// download couldn't be handled because user has disabled download manager app on the device
// TODO show some notice to the user
}
}

cap vs len of slice in golang : <p>What is the difference between cap and len of a slice in golang?</p>
<p>According to definition:</p>
<p>A slice has both a length and a capacity.</p>

<p>The capacity of a slice is the number of elements in the underlying array, counting from the first element in the slice.</p>
<pre><code>x := make([]int, 0, 5) // len(b)=0, cap(b)=5

rebase vs reset vs revert? I just want to roll back : <p>Let's say I make a number of commits, let's call them 1, 2, 3, 4, 5, and 6 (hashes).</p>
<p>Let's say I'm on a commit with hash 6. All I want to do is go back to hash 3, make it so the state of my codebase was as it was when I commited to hash 3 as if the other commit's never happened.</p>
<p>When I look at answers like <a href="https://stackoverflow.com/questions/1895059/revert-to-a-commit-by-a-sha-hash-in-git">this</a>, it seems like everybody has a different answer. <code>reset</code>, <code>revert</code>, <code>rebase</code>? I'm not even sure I know the difference between those three words in english.</p>

Android App crashes upon creating Sqlite DB : I'm trying to use a database in my android app but when I start the activity that would use the DB helper/ Contract it crashes. I've tried some query validators and I don't seem to find any errors.
The following I use to use my dbhelper but the second line causes the crash.
DBhelper dbHelper = new DBhelper(this);
mDatabase = dbHelper.getWritableDatabase();
Code for my dbcontract is:
public final class DBcontract {
private DBcontract(){}
public static class DB_table1 implements BaseColumns {
public static final String TABLE_Name = "Timer_table";
public static final String COL_1 = "id";
public static final String COL_2 = "Title";
public static final String COL_3 = "Startvalue";
public static final String COL_4 = "Endvalue";
public static final String COL_5 = "Timer";
}
}
and the dbhelper is:
public class DBhelper extends SQLiteOpenHelper {
public static final int DATABASE_VERSION = 1;
public static final String DATABASE_NAME = "archeage.db";
//Create table query
public static final String CREATE_TABLE =
"" + "CREATE TABLE " + TABLE_Name + " ( "
+ DBcontract.DB_table1.COL_1 + " INTEGER PRIMARY KEY AUTO_INCREMENT, "

//delete table query
public static final String DELETE_TABLE = "DROP TABLE IF EXISTS " + TABLE_Name;

Kotlin and idiomatic way to write, 'if not null, else...' based around mutable value : <p>Suppose we have this code:</p>
<pre><code>class QuickExample {
fun function(argument: SomeOtherClass) {
if (argument.mutableProperty != null ) {
doSomething(argument.mutableProperty)
} else {
doOtherThing()
}
}
fun doSomething(argument: Object) {}
fun doOtherThing() {}
}
class SomeOtherClass {
var mutableProperty: Object? = null
}
</code></pre>
<p>Unlike in Java, where you could be left alone to worry about null dereferencing at runtime, this doesn't compile - quite rightly. Of course, <code>mutableProperty</code> may no longer be null once within the 'if'.</p>
<p>My question is what's the best way to handle this?</p>
<p>A few options are apparent. Without using any new Kotlin language features, the simplest way is obviously to copy the value to a method-scope one that won't subsequently change.</p>
<p>There's this:</p>
<pre><code>fun function(argument: SomeOtherClass) {
argument.mutableProperty?.let {
doSomething(it)
return
}
doOtherThing()
}
</code></pre>
<p>This has the obvious disadvantage that you need to return early or otherwise avoid executing the subsequent code - OK in certain, small contexts, but has a smell to it.</p>
<p>Then there's this possibility:</p>
<pre><code>fun function(argument: SomeOtherClass) {
argument.mutableProperty.let {
when {
it != null -> {
doSomething(it)
}
else -> {
doOtherThing()
}
}
}
}
</code></pre>
<p>but whilst it has greater clarity of purpose, arguably it's more unwieldy and verbose than the Java-style way of dealing with this.</p>
<p>Am I missing anything, and is there a preferred idiom with which to achieve this?</p>

Share a list between different processes in python : <p>I have the following problem. I have written a function that takes a list as input and creates a dictionary for each element in the list. I then want to append this dictionary to a new list, so I get a list of dictionaries. I am trying to spawn multiple processes for this. My problem here is that I want the different processes to access the list of dictionaries as it is updated by other processes, for example to print something once the has reached a certain length.
My example would be like this:</p>
<pre><code>import multiprocessing
list=['A', 'B', 'C', 'D', 'E', 'F']
def do_stuff(element):
element_dict={}
element_dict['name']=element
new_list=[]
new_list.append(element_dict)
if len(new_list)>3:
print 'list > 3'
###Main###
pool=multiprocessing.Pool(processes=6)
pool.map(do_stuff, list)
pool.close()
</code></pre>
<p>Right now my problem is that each process creates its own <code>new_list</code>. Is there a way to share the list between processes, such that all dictionaries are appended to the same list? Or is the only way to define the <code>new_list</code> outside of the function?</p>

Generate a pandas dataframe from ordereddict? : <p>I am trying to create a pandas dataframe from an ordereddict to preserve the order of the values. But for some reason after creating the dataframe the fields are messed up again.</p>
<p>Here's the list of ordereddicts:</p>
<pre><code>[OrderedDict([
('key_a',
'value_a'),
('key_b',
'value_b'),
]),
OrderedDict([
('key_a',
'value_c'),
('key_b',
'value_d'),
])
]
</code></pre>
<p>Now how should I create a pandas DataFrame from these? What I am looking for is something like that (the important thing is the key_a and key_b etc column name order):</p>
<pre><code> key_a key_b
0 value_a value_b
1 value_c value_d
</code></pre>
<p>I have tried:</p>
<pre><code>pd.DataFrame.from_records(orderedDictList)
pd.DataFrame.from_dict(orderedDictList)
</code></pre>
<p>Feel free to ask any additional questions.</p>

Why gradle jars are written in `build/libs`? : <p>According to the <a href="https://docs.gradle.org/current/dsl/org.gradle.api.tasks.bundling.Jar.html" rel="noreferrer">documentation of the Jar plugin</a>, the output directory is controlled by the <code>destinationDir</code> property:</p>
<blockquote>
<ul>
<li><p><strong>File</strong> <code>destinationDir</code></p>
<p>The directory where the archive is generated into.</p>
<p>Default with java plugin: <code>project.distsDir</code></p></li>
</ul>
</blockquote>
<p>Looking at the <a href="https://docs.gradle.org/current/dsl/org.gradle.api.Project.html" rel="noreferrer">documentation of the Project class</a> the same property is mentioned:</p>
<blockquote>
<p><strong>Properties added by the <code>java</code> plugin</strong></p>
<ul>
<li><code>distsDir</code>: The directory to generate TAR and ZIP archives into.</li>
<li><code>distsDirName</code>: The name for the distributions directory. This in interpreted relative to the project' build directory.</li>
</ul>
</blockquote>
<p>And Googling a bit I find <a href="https://docs.gradle.org/current/dsl/org.gradle.api.plugins.BasePluginConvention.html#org.gradle.api.plugins.BasePluginConvention:distsDirName" rel="noreferrer">a document specifying their defaults</a>:</p>
<blockquote>
<ul>
<li><p><strong>File</strong> <code>distsDir</code> (read-only)</p>
<p>The directory to generate TAR and ZIP archives into.</p>
<p>Default with java plugin: <code>${project.buildDir}/${project.distsDirName}</code></p></li>
<li><p><strong>String</strong> <code>distsDirName</code></p>
<p>The name for the distributions directory. This in interpreted relative
to the project' build directory.</p>
<p>Default with java plugin: <code>'distributions'</code></p></li>
</ul>
</blockquote>
<p>All these documents point to the same Gradle version, that matches the one I have installed.</p>
<p>I add this in my <code>build.gradle</code> to check the real values of these properties:</p>
<pre><code>println("distsDirName = " + project.distsDirName)
println("distsDir = " + project.distsDir.toString())
jar {
println("jar.destinationDir = " + destinationDir)
}
</code></pre>
<p>And finally, I run <code>./gradlew</code> and check the output:</p>
<pre><code>distsDirName = distributions
distsDir = /home/ntrrgc/myProject/build/distributions
jar.destinationDir = /home/ntrrgc/myProject/build/libs
</code></pre>
<p>Why does <code>jar.destinationDir</code> not respect its documented default?</p>

html css3 how to center multiple divs in other div vertically and horizonally with multiple lines of divs made by clear: both : I have such a html:
<div id="content">
<div id="letter1">T</div>
<div id="letter2">H</div>
<div id="letter3">A</div>
<div id="letter4">T</div>
<div id="letter5" style="clear: both;">W</div>
<div id="letter6">O</div>
<div id="letter7">R</div>
<div id="letter8">K</div>
<div id="letter9">S</div>
</div>
As you can see I have a string divided on chars, each char in another div. **I want to have each word in separate line, each centered horizontally. Take under consideration `clear: both;` to start new line.** Vertical alignment woudl be nice but is not necessity. Number of words (lines) and letters vary depeneding on situation.
All the guides i have found about centering tell about centering multiple divs but they are in one line or are centered after free break line (there is no space for next div in line so it takes next line with remaining divs and center the line). Can anybody help me?

How do I code a program that will create drop down lists from input and populate columns in another sheet with drop downs : <p>I am new to VBA and currently know how to create Macros using the "Record Macro" option. I need to code something that does multiple steps in VBA.</p>
<p>I will have an unknown number of columns that I need the program to go through and check if the second row has a value in it.(These columns and rows will be input from a user so the number of columns or entries per row is unknown). </p>
<p>The values under each column are the possible categories a user will later choose from for that specific variable. So in Sheet 1 there is a variable "Sex" there will be one row under it saying "female" and another row under that saying "male". These have to be made into a drop down list and pasted under another sheet (Sheet2) in which the same column names (Sex) will now have drop downs under them.</p>
<p>Steps to take: </p>
<p>1) IF Column(i)'s Row 2 is not empty</p>
<p>2) Then define all rows below it as a list and make a drop down of this list</p>
<p>3) Then paste this drop down under a column that matches the name of the Column(i) in another sheet</p>
<h1>SHEET 1 (what i have)</h1>
<pre><code>Age | Sex | Race | Height
------------------------------------
[EMPTY] |Female |Asian |[EMPTY]
[EMPTY] |Male |Black |[EMPTY]
[EMPTY] |[EMPTY] |Hispanic|[EMPTY]
[EMPTY] |[EMPTY] |Native A|[EMPTY]
[EMPTY] |[EMPTY] |White |[EMPTY]
[EMPTY] |[EMPTY] |Other |[EMPTY]
</code></pre>

<h1>SHEET 2 (what I want)</h1>
<pre><code>AGE | Sex | Race | Height

[EMPTY] | [dropdown of sex] | [dropdown of race] |[EMPTY]

apply 1 css class which applies more than 1 class to an element : <p>Lets say I use multiple bootstrap classes to achieve my desired button effect.</p>
<pre><code>styleClass="btn btn-lg btn-block btn-success my_wrap"
</code></pre>
<p>Can I do something like this with css that allows me to have a single style defined in my html but in my css defining multiple bootstrap classes, utilising bootstrap and custom styling, to effectively wrapper them into a single super class?</p>
<pre><code>styleClass="my-button-ultimate"
</code></pre>
<p>e.g. maybe css like this (my_wrap is my custom class the others are std bootstrap):</p>
<pre><code>.my-button-ultimate{
.btn, .btn-lg, .btn-block, .btn-success, .my_wrap
}
.my_wrap{
white-space: normal;
}
</code></pre>
<p>I could possibly do this:</p>
<pre><code><style>
.my-button-ultimate{
width:100%;
height:60px;
white-space: normal;
}
</style>
...
...
<div styleClass="btn my-button-ultimate">My Button</div>
</code></pre>
<p>But it does not take full advantage of bootstrap, and still does not give me a single class in my element.</p>
<p>I checked out this answer without success. LESS seems like what I want but I do not know how to implement it just yet, and I want to find out if there is a simple answer to combine classes into 1.

How does react-router persist location state over page refreshes? : <p>I am just so very confused.</p>
<p>I have a workflow where someone can start to fill out a form for a product. It is a long form and I want to save progress to the server as they type (but not until they fill it out for a bit). So we start at a url for creating the form, after they've typed for a bit, we POST to create a resource on the server, and after the request finishes, we update the url to the edit route with the new id.</p>
<p>In other words, you start filling out the form at url <code>/product</code> then after you've filled it out for a bit the url shifts to <code>/product/123</code>. After that, loading that URL gives you your form.</p>
<p>So basically I have</p>
<pre><code><Route path={`/product`} exact component={CreateProduct} />
</code></pre>
<p>and</p>
<pre><code><Route exact={true} path="/product/:productId" render={({
match: {params: {productId}},
location: {state: {data}={}}
}) => (
<EditProduct productId={productId} initialData={data}
)} />
</code></pre>
<p>See that state? That's because the way I do the switch over from create to edit mode is something like this</p>
<pre><code>const id = await apiFetch(`/api/product`, data, {method: `POST`})
this.props.history.push({pathname: `/product/${id}`, state: {data} })
</code></pre>
<p>in the constructor of my <code><EditProduct></code> component I have</p>
<pre><code>constructor({productId, initialData}) {
this.super()
this.state = {}
if(initialData)
this.setState({data: initialData})
else
getProduct(productId).then(({data}) => this.setState({data}))
}
</code></pre>
<p>By doing that, the initial data into the <code><EditProduct></code> is seeded from the <code><CreateProduct></code> component and I don't need to reload it from the server or anything.</p>
<p>This works, the transition is smooth, the url updates, and everything is hunky dory.</p>
<p>I can now continue editing the <code><EditProduct></code> component and it saves properly. I can open a new tab to the same url and it loads everything up and I can continue. This happens because in that situation <code>initialData</code> is <code>undefined</code> so its loaded from the server. yay!</p>
<p><strong>BUT</strong></p>
<p>If I instead <em>refresh <strong>the original</strong> tab</em> things get weird. Any changes that have accumulated since the save are lost. Drilling down in the debugger I see the issue is that <code>initialData</code> passed from the <code>location.state.data</code> object is not empty - it is the initial object from when the product was first created. </p>
<p>So where on earth does it come from? I just did a full page refresh (even a "hard" refresh with no cache and devtools open). That data isn't in the URL (and in fact copy pasting the url into another tab in the same window doesn't have this issue).</p>
<p>The only mechanism I'm aware of that can persist data across refreshes but not to new tabs like this is <code>sessionStorage</code>, yet when I check it in the console, I am told</p>
<pre><code>> sessionStorage
< Storage {length: 0}
</code></pre>
<p>I've even thought that maybe react router is manipulating session storage just before the page unloads and just after it loads, but breaking on the first line of my javascript bundle shows the exact same thing.</p>
<p>So how on earth is this persistence happening!?</p>

Why I cant get previous url in controller? : I work on my single page application project I use angujarjs 1.5.
At some point in my controller I need to get previous url.
I tried to use this row to get previous url:
var prevUrl = $document[0].referrer;
and this:
var prevUrl2 = document.referrer;
But `prevUrl` and `prevUrl2` are always empty.
When I use this row to go back:
$window.history.back();
It works fine.
Any idea why 'prevUrl' and 'prevUrl2' is empty?
Please help me!
