I have a user on my h2 database and to verify if the user credentials are correct and don't know what is advised.Should decrypt both passwords and compare them (I think that not the correct way to do it of course) or should I use another mechanism to verify if the user's credetials are right?</p>

Create a new dataframe column with the first element of elements in another column in R : <p>I want to create a new column in my dataframe such that it is formed by the first element (or 2 elements) of elements in another column in the same dataframe. E.g.</p>
<pre><code> columnA
1 "1234"
2 "9876"
3 "4567"
</code></pre>
<p>Turns into:</p>
<pre><code> columnA columnB
1 "1234" "12"
2 "9876" "98"
3 "4567" "45"
</code></pre>
<p>I tried with the dplyr library like this:</p>
<pre><code>dataframe %>%
mutate( columnB = columnA[1:2] )
</code></pre>
<p>But this is trying to retrieve the first two rows.</p>
<p>If anyone knows anyway to do this fast (preferably with dplyr library), I would appreciate it a lot. Thanks in advance.</p>

'mat-card' is not a known element in Angular 7 : <p>I've seen a lot of questions on this but doesn't seem to be the same issue Im encountering. I have just created my 2nd angular project. I have a new component under <code>src/app/employees</code> where I am trying to use in employees.component.html . The error I am getting is:</p>
<pre><code>Uncaught Error: Template parse errors:
'mat-card' is not a known element:
1. If 'mat-card' is an Angular component, then verify that it is part of this module.
2. If 'mat-card' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("[ERROR ->]<mat-card> </mat-card>
</code></pre>
<p>Now, in app.module.ts I have:</p>
<pre><code>import { BrowserModule } from "@angular/platform-browser";
import { BrowserAnimationsModule } from "@angular/platform-browser/animations";
import { LOCALE_ID, NgModule } from "@angular/core";
import { HttpClientModule, HTTP_INTERCEPTORS } from "@angular/common/http";

<option value="Product1" id="2">
<option value="Product1" id="3">
<option value="Product2" id="4">

<p>Options are dynamically generated from database depending on the search query typed in input field.
There are situations when multiple products come with same name but other different properties like rate or unit.

Tracking the progress between Queues in a Map : <p>I have currently two queues and items traveling between them. Initially, an item gets put into <code>firstQueue</code>, then one of three dedicated thread moves it to <code>secondQueue</code> and finally another dedicated thread removes it. These moves obviously include some processing. I need to be able to get the status of any item (<code>IN_FIRST</code>, <code>AFTER_FIRST</code>, <code>IN_SECOND</code>, <code>AFTER_SECOND</code>, or <code>ABSENT</code>) and I implemented it manually by doing the update of the <code>statusMap</code> where the queue gets modified like</p>
<pre><code>while (true) {
Item i = firstQueue.take();
statusMap.put(i, AFTER_FIRST);
process(i);
secondQueue.add(i);
statusMap.put(i, IN_SECOND);
}
</code></pre>
<p>This works, but it's ugly and leaves a time window where the status is inconsistent. The inconsistency is no big deal and it'd solvable by synchronization, but this could backfire as the queue is of limited capacity and may block. The ugliness bothers me more.</p>
<p>Efficiency hardly matters as the processing takes seconds. Dedicated threads are used in order to control concurrency. No item should ever be in multiple states (but this is not very important and not guaranteed by my current racy approach). There'll be more queues (and states) and they'll of different kinds (<code>DelayQueue</code>, <code>ArrayBlockingQueue</code>, and maybe <code>PriorityQueue</code>).</p>
<p><em>I wonder if there's a nice solution generalizable to multiple queues?</em></p>

Go: invalid operation - type *map[key]value does not support indexing : <p>I'm trying to write a function that modifies original map that is passed by pointer but Go does not allow it. Let's say I have a big map and don't want to copy it back and forth.</p>
<p>The code that uses passing by value is working and is doing what I need but involves passing by value (<a href="https://play.golang.org/p/-UUiJ9vbMa" rel="noreferrer">playground</a>):</p>
<pre><code>package main

type Currency string
type Amount struct {

current, ok := b[amount.Currency]
if ok {
b[amount.Currency] = current + amount.Value
} else {
b[amount.Currency] = amount.Value
}
return b
}
func main() {
b := Balance{Currency("USD"): 100.0}
b = b.Add(Amount{Currency: Currency("USD"), Value: 5.0})
fmt.Println("Balance: ", b)
}
</code></pre>
<p>But if I try to pass parameter as pointer like here (<a href="https://play.golang.org/p/kVCAt7074j" rel="noreferrer">playground</a>):</p>
<pre><code>func (b *Balance) Add(amount Amount) *Balance {
current, ok := b[amount.Currency]
if ok {
b[amount.Currency] = current + amount.Value
} else {
b[amount.Currency] = amount.Value

return b

</code></pre>
<p>I'm getting compilation error:</p>

Connect to host mongodb from docker container : <p>So I want to connect to my mongodb running on my host machine (DO droplet, Ubuntu 16.04). It is running on the default <code>27017</code> port on localhost.</p>
<p>I then use <a href="https://github.com/zodern/meteor-up" rel="noreferrer">mup</a> to deploy my Meteor app on my DO droplet, which is using docker to run my Meteor app inside a container. So far so good.
A standard <code>mongodb://...</code> connection url is used to connect the app to the mongodb.
Now I have the following problem:</p>
<p><code>mongodb://...@localhost:27017...</code> obviously does not work inside the docker container, as <code>localhost</code> is not the host's localhost.</p>
<p>I already read many stackoverflow posts on this, I already tried using:</p>
<ul>
<li><code>--network="host"</code> - did not work as it said <code>0.0.0.0:80</code> is already in use or something like that (nginx proxy)</li>
<li><code>--add-host="local:<MY-DROPLET-INTERNET-IP>"</code> and connect via <code>mongodb://...@local:27017...</code>: also not working as I can access my mongodb only from localhost, not from the public IP</li>
</ul>
<p>This has to be a common problem!</p>
<p><strong>tl;dr</strong> - What is the proper way to expose the hosts <code>localhost</code> inside a docker container so I can connect to services running on the host? (including their ports, e.g. 27017).</p>
<p>I hope someone can help!</p>

Firebase authentication vs AWS Cognito : <p>We are building a mobile and web app on AWS using API Gateway and Lambda and are currently evaluating if we should use all the AWS Mobile Servcies (Cognito, Analytics, Mobile Hub, etc) or if we should use Firebase instead (which offers some advantages like remote config).</p>
<p>I think using the non-funtional part of firebase like Analytics, Remote Config, Crash Reports, Notification should be fine with the AWS backend. The part were I am not certain is the Authentication Layer. </p>
<p>AWS Cognito integrates nicely into API Gateway and Lamdba e.g. only authenticated users can execute certain API calls. </p>
<p>Can the same behaviour be reached if we use Firebase Authentication instead?
Any good or bad experience with this?</p>

Most recent value or last seen value : <p>Prometheus is built around returning a <em>time series</em> representation of metrics. In many cases, however, I only care about what the state of a metric is <em>right now</em>, and I'm having a hard time figuring out a reliable way to get the "most recent" value of a metric.</p>
<p>Since right now it's getting metrics every 30 seconds, I tried something like this:</p>
<pre><code>my_metric[30s]
</code></pre>
<p>But this feels fragile. If metrics are dated any more or less than 30 seconds between data points, then I either get back more than one or zero results.</p>
<p>How can I get the most recent value of a metric?</p>

java equals true with different hashcodes : I am going through the java.lang.Object API which states the below the point on objects equality:
https://docs.oracle.com/javase/7/docs/api/java/lang/Object.html
**public boolean equals(Object obj):**
> It is generally necessary to override the hashCode method whenever
> this method is overridden, so as to maintain the general contract for
> the hashCode method, which states that equal objects must have equal
> hash codes.
**Now to test the above theory on "equal objects must have equal hash codes", I have come up with the below simple code:**
public class Product {
private String name;
public Product(String name) {
this.name = name;
}
@Override
public boolean equals(Object obj) {
//always returns true for all objects
return true;
}
@Override
public int hashCode() {
//Different hascodes for different objects
if(name.equals("PRODUCT1")) {
return 10;
} else {
return 20;
}
}
public static void main(String[] args) {
Product p1 = new Product("PRODUCT1");
Product p2 = new Product("PRODUCT2");
if(p1.equals(p2)) {
System.out.println(" p1 p2 are equal **** ");
} else {
System.out.println(" p1 p2 are NOT equal **** ");
}
}
}
***Output:***
p1 p2 are equal ****
**So, is n't the above code violating/contradicting the API statement "equal objects must have equal hash codes" i.e., equal objects need NOT have same hashcodes ?
Or else what am I missing in the above code ?**

<p>Then I am applying DBSCAN clustering algorithm on distance matrix.</p>
<pre><code> from sklearn.cluster import DBSCAN

</code></pre>
<p>I don't know how to choose eps & min_samples value. It clusters the points which are way too far, in one cluster.(approx 2 km in distance) Is it because it calculates euclidean distance while clustering? please help.</p>

Inheriting Mongoose schemas : <p>I wanted to make a base 'Entity Schema', and other model entities would inherit from it.
I did it, kinda, but then strange thing happened. </p>
<p>Those are my schemas: </p>
<ul>
<li>AbstractEntitySchema</li>
<li>MessageSchema</li>
<li>UserSchema</li>
<li>RoomSchema</li>
</ul>
<p>File: <a href="https://github.com/mihaelamj/nodechat/blob/master/models/db/mongo/schemas.js" rel="noreferrer">https://github.com/mihaelamj/nodechat/blob/master/models/db/mongo/schemas.js</a></p>
<p>But in MongoDB, they are all saved in the same document store: 'entity models' not separate ones, like Messages, Users..
Did I get what was supposed to happen, but not what I wanted, separate stores?
If so I will just make a basic JSON/object as entity and append the appropriate properties for each entity. Or is there a better way?
Thanks.</p>

jQuery(...).autoComplete is not a function : <p>I'm trying to get autoComplete() to work from jQuery-ui. I've created a fiddle to show my code:</p>
<p><a href="https://jsfiddle.net/4s4dzwn1/" rel="nofollow">https://jsfiddle.net/4s4dzwn1/</a></p>
<p>My JS:</p>
<pre><code>jQuery(function(){
jQuery('#autocomplete').autoComplete({
source: ["ActionScript",
"Bootstrap",
"C",
"C++",
"Ecommerce",
"Jquery",
"Groovy",
"Java",
"JavaScript",
"Lua",
"Perl",
"Ruby",
"Scala",
"Swing",
"XHTML"]
});
});
</code></pre>
<p>My HTML:</p>
<pre><code><script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>
<form>
<input id="autocomplete">
</form>
</code></pre>
<p>It's throwing an error that says autoComplete is not a function. My understanding is that autoComplete is a part of jQuery-ui (which is included), and that jQuery-ui should be included <strong>after</strong> jquery. Please correct me where I'm wrong.</p>

Android AlarmManager triggers every "round" 10 minutes : <p>I use the AlarmManager in my app as follows:</p>
<pre><code>alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), AlarmManager.INTERVAL_HALF_DAY, intent);
</code></pre>
<p>Which I'd expect to trigger the alarm somewhere between 12 and 24 hours from each trigger. However, the behavior specifically on HTC devices is rather weird:</p>
<p>Each time the alarm is triggered, we send an HTTP request to our servers. On all devices, we see requests coming to the server uniformly over time, but on HTC devices there are spikes every "round" 10 minutes (XX:10, XX:20, ...):
<a href="https://i.stack.imgur.com/ZDXJK.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ZDXJK.png" alt="enter image description here"></a></p>
<p>What can be the cause for these spikes? And why would it only be on HTC devices?</p>

Suppose that n women check their coats at a concert : <p>I have a seemingly difficult algorithm that I must construct, and I'm not sure where to even start. Here it is:</p>
<p>Suppose that n women check their coats at a concert. However, at the end of the night,
the attendant has lost the claim checks and does not know which coat belongs to whom.
All of the women came dressed in black coats that were nearly identical, but of different
sizes. The attendant can have a woman try a coat, and find out whether the coat fits
(meaning it belongs to that woman), or the coat is too big, or the coat is too small.
However, the attendant cannot compare the sizes of two coats directly, or compare the
sizes of two women directly. Describe how the attendant can determine which coat
belongs to which woman in expected O(n log n) time. </p>
<p>I've thought of ways to do this, but none come close to O(n log n) time.
Any help with this would be greatly appreciated.</p>

Strange error with C++ console app when running a for loop : <p>So I was messing around with the dimensions of an array, starting it with [25][25]. I've eventually found the best dimensions of it ([21][25]) but I've forgot to change the condition in the for loop which is displaying the array (Initially it was y<25 and it had to be y<21). The program ran just fine but there was a strange error. What the array was displaying was pretty strange and also it made sounds (the sound is very familiar, although I can't tell exactly what it is. I can guess it is the one you get when you try to open a shortcut which file's destination was deleted but I'm not very sure, as I've said very familiar tho.)<a href="https://i.stack.imgur.com/z6SrE.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/z6SrE.png" alt="enter image description here"></a> I have also uploaded a screenshot and you can see the error for yourself ( the 2 lines before the "Process returned 0" one). Any idea why these specific characters tho ( I mean a smiley face? come on.)?</p>

<li>Do I understand right that all OSGi application will be one unnamed module?</li>
<li>If #1 yes, then how does <code>Bundle.update()</code> works? Is bundle reloaded to unnamed module?</li>
