How can I make a hidden button menu with a scroll bar? : I want to have buttons hidden above my normal content in the scroll view that will appear when I swipe down. Currently I have these buttons in a stack view in the scroll view. I want the view to snap between two positions where the buttons are not visible and where they are, but also may need to scroll if the actual content is larger than the screen. I've tried content offset which works at first but then if it is scrolled and the content is smaller than the screen it will always show the buttons. Any ideas on how to do this? Thanks.

Get only dataValues from Sequelize ORM : <p>I'm using the sequelize ORM to fetch data from a PSQL DB. However, when I retrieve something, a whole bunch of data is given. The only data I want is inside 'dataValues'. Of course, I can use object.dataValues. But, is there any other good solutions?</p>

Autofac - SingleInstance HttpClient : <p>Have read in various places that HttpClient should be reused rather than a new instance every time.</p>

scikit-learn return value of LogisticRegression.predict_proba : <p>What exactly does the <code>LogisticRegression.predict_proba</code> function return?</p>
<p>In my example I get a result like this:</p>
<pre><code>[[ 4.65761066e-03 9.95342389e-01]
[ 9.75851270e-01 2.41487300e-02]
[ 9.99983374e-01 1.66258341e-05]]
</code></pre>
<p>From other calculations, using the sigmoid function, I know, that the second column are probabilities. The <a href="http://scikit-learn.org/stable/modules/generated/sklearn.linear_model.LogisticRegression.html#sklearn.linear_model.LogisticRegression.predict_proba" rel="noreferrer">documentation</a> says, that the first column are <code>n_samples</code>, but that can't be, because my samples are reviews, which are texts and not numbers. The documentation also says, that the second column are <code>n_classes</code>. That certainly can't be, since I only have two classes (namely <code>+1</code> and <code>-1</code>) and the function is supposed to be about calculating probabilities of samples really being of a class, but not the classes themselves.</p>
<p>What is the first column really and why it is there?</p>

Reshaping data with R : <p>I have my data in the below table structure:</p>
<pre>
Person ID | Role | Role Count
-----------------------------
1 | A | 24
1 | B | 3
2 | A | 15
2 | B | 4
2 | C | 7
</pre>
<p>I would like to reshape this so that there is one row for each Person ID, A column for each distinct role (e.g. A,B,C) and then the Role Count for each person as the values. Using the above data the output would be:</p>
<pre>
Person ID | Role A | Role B | Role C
-------------------------------------
1 | 24 | 3 | 0
2 | 16 | 4 | 7
</pre>
<p>Coming from a Java background I would take an iterative approach to this:</p>
<ol>
<li>Find all distinct values for Role </li>
<li>Create a new table with a column for PersonID and each of the distinct roles </li>
<li>Iterate through the first table, get role counts for each Person ID and Role combination and insert results into new table.</li>
</ol>
<p>Is there another way of doing this in R without iterating through the first table? </p>
<p>Thanks</p>

<p>I have it loaded up as a single string and I am wondering what the best way would be to convert it into a dictionary of the form:</p>

</code></pre>
<p>My first instinct is to go line by line through the string and check to see if a few different regular expressions match and go from there, but I'd also have to include logic to handle what to do after a variable name is matched, then the citation, and the data, etc.</p>
<p>Is there a better way to do this? Possibly with some kind of template to extract the variable name, citation, and data as mentioned? I'm sure this is a fairly common task so I'm assuming there are more standard methods/tools for this.</p>

Python K-Means Z-Transfrom : i want to use the k-means to cluster my results, but I have a lot of question.
<http://scikit-learn.org/stable/modules/generated/sklearn.cluster.KMeans.html#sklearn.cluster.KMeans>
My input data looks like this:
`ID ABC XYZ UVW MSE
10 A X U 102000
12 B Y V 9000`
Do I transform my data set in z-tranfromation?
Because I have numbers and character...
When i get result of Kmeans, should i run it often to crosschecking my results?
I want to know which ID is in which cluster. How i get this infromation out of software?
Thx in Advance.

Emit an event when a specific piece of state changes in vuex store : <p>I have a vuex store with the following state:</p>

<p>Inside a component I want to watch for changes to the <code>authed</code> state and send an AJAX call to the server. It needs to be done in various components.</p>
<p>I tried using <code>store.watch()</code>, but that fires when either <code>id</code> or <code>authed</code> changes. I also noticed, it's different from <code>vm.$watch</code> in that you can't specify a property. When i tried to do this:</p>
<pre><code>store.watch('authed',function(newValue,oldValue){
//some code
});

<p>I got this error:</p>

Converting 2D Image into 3D Using three.js and Other Tools : <p>I have an image of a data visualization that I want to make into 3D. I was wondering how I would be able to convert this image into 3D using three.js and other possible tools. I have no idea what to do.</p>
<p>I heard that there is something called WebGL Javascript API so maybe I can use that but I don't know how to begin and whether or not it can be used in this situation. I also read somewhere that you cannot make a 3D image from a 2D one without some information about the 3rd dimension. This missing information can come from a second photo, an AI software, or a 3D digital model.</p>
<p>I also read that I can make a 3D model of the image in Blender and then import it into three.js.</p>
<p>Does anyone know how I can do this? </p>
<p><strong>I want to try to do the coding in JS fiddle if it's possible unless other software/tools are needed outside of JS fiddle. I see that you can import the three.js library there.</strong></p>
<p>The current visualization I have made is </p>

Convert column counts into data frame with new columns : <p>I have a dataset of baseball play-by-play data. Here's a simplified example:</p>

'C','C','C','C','C','C','C')
event <- c("OUT","WALK","OUT","OUT","HR","WALK","OUT",
"WALK","OUT","HR","WALK","OUT","OUT","WALK",
"HR","HR","WALK","WALK","HR","OUT","WALK")
df <- data.frame(team, event)
df
team event
1 A OUT
2 A WALK
3 A OUT
4 A OUT
5 A HR
6 A WALK
7 A OUT
8 B WALK
9 B OUT
10 B HR
11 B WALK
12 B OUT
13 B OUT
14 B WALK
15 C HR
16 C HR
17 C WALK
18 C WALK
19 C HR
20 C OUT
21 C WALK
</code></pre>
<p>I would like to create a new data frame that shows the number of times each event occurred for each team, with each event represented by a new column, like this:</p>
<pre><code> team OUT WALK HR
1 A 4 2 1
2 B 3 3 1
3 C 1 3 3

Python scrabble score from file : I got a list of points for each letter:
SCRABBLES_SCORES = [(1, "E A O I N R T L S U"), (2, "D G"), (3, "B C M P"),
(4, "F H V W Y"), (5, "K"), (8, "J X"), (10, "Q Z")]
And in file I have to find word with the highest score
I have a problem, because I don't know how to examine new line.
I tried this, but its never ending loop:
max = 0
help = 0
file = open("dictionary.txt", "r")
for line in file:
for l in line:
while(l != '\n'):
help += LETTER_SCORES.get(l)
if(help > max):
max = help
else:
continue
help = 0
print(max)
Does anybody know what Im doing wrong?

Mysterious character output in C : I had come across this code in K & R:
int scanline (char str [], int lim) /* Line will be read in 'str []', while lim is the maximum characters to be read */
{
int c, len, j; /* 'len' will have the length of the read string */
j = 0; /* Initializing 'j' */
for (len = 0; (c = getchar ()) != EOF && c != '\n'; ++len) /* Reading a character one by one, till the user enters '\n', and checking for failure of 'getchar' */
{
if (len < (lim -2)) /* Checking that string entered has not gone beyond it's boundaries. '-2' for '\n' and '\0' */
{
str [j] = c; /* Copying read character into 'string [j]' */
++ j; /* Incrementing 'j' by 1 */
}
}
if (c == '\n') /* Checking if user has finished inputting the line */
{
str [j] = c; /* Copying newline into string */
++j;
++ len;
}
return len; /* Returning number of characters read */
}
In the K & R, it is known as `getline`, but I made changes, added comments, and thus defined it as `scanline`. To test this, I made a demo program:
#include <mocl/cancel.h>
int main (int argc, char **argv)
{
int len;
char str [50];
len = scanline (str, 50);
printf ("len = %d\n str = %s\n", len, str);
return 0;
}
The required headers and the function was in my own library, `cancel.h`. Then when I compiled my program, it was successful. Although, when I ran the executable, I got unexpected output (I cannot type it as I get a character which when I copy, it just gets pasted as 'm'):
[![enter image description here][1]][1]
The mysterious character is [![enter image description here][2]][2] which when I copy, gets copied as the letter `m`. Also, when I run my program with different inputs, I get different mysterious outputs:
[![enter image description here][3]][3]
In another case, I get perfect output, just that a blank line is printed:
[![enter image description here][4]][4]
I had also come across [this](http://stackoverflow.com/questions/35651800/what-is-this-mysterious-output-in-c) question, in which the user gets the same symbol.
------------
**_What have I done till now?_**
I searched a lot, and I could not find any clue about [![enter image description here][5]][5] this character, but if you see carefully, in the second image, I get more characters when I enter "hi this is ashish". One of them is the slash, and one is [![enter image description here][6]][6]. But I get another character [![enter image description here][7]][7]. I got [this](https://rosettacode.org/wiki/Strip_control_codes_and_extended_characters_from_a_string#C) link which was showed how to reproduce it, and explained it, although I could not understand. When you run the code given there, you get a lot of characters, and one of them is [![enter image description here][8]][8]. Although, even the author of that article could not copy it, and has not posted it. So here's the output:
[![enter image description here][9]][9]
That was the actual output, as that's not clear, here's a cut out version:
[![enter image description here][10]][10]
So basically I got to know that both the characters [![enter image description here][11]][11] and [![enter image description here][12]][12] are extended characters from a string. At that point, I actually figured out what was causing the problem in `scanline`.
The lines
if (c == '\n') /* Checking if user has finished inputting the line */
{
str [j] = c; /* Copying newline into string */
++j;
++ len;
}
were causing the problems as you were copying a newline into the string. It worked, but I'm not sure why, as doing that was just a guess. I searched but still could not find the reason.
---------------
**_My Questions_**
- How does removing those lines make the program work properly?
- What are the characters [![enter image description here][13]][13] and [![enter image description here][14]][14]? What are they supposed to do and how did they appear over here?
- Are there any more characters like this?
- Why can't those characters be copied?
- Is it Undefined Behavior?
**NOTE:** I know this questions lengthy, but I'll make sure and offer a bounty once that "question eligible for bounty in 2 days" gets over.

WordPress CPT With Ability to Login and Register : <p>We're responsible for a WordPress plugin which, as part of it's functionality, has a Custom Post Type called 'Applicant'. These are applicants looking to purchase property so against a post you can record things like their contact details, and search requirements.</p>
<p>Now... it's come to light that we need to enable these applicants to be able to login and perform various actions such as save properties to a 'Favourites' list, or edit their own requirements.</p>
<p>If we were building the plugin from scratch I would've just done them as users, however this is a plugin used by hundreds of people so we don't have that luxury and must keep it as a CPT.</p>
<p>My question is... how can I/should I keep it a CPT whilst allowing these people to login and register.</p>
<p>My two initial thoughts are:</p>
<ol>
<li>For every custom post you have a WordPress user and keep the two synced (i.e. if the user is deleted, the custom post gets deleted at the same time). That way you could use the built-in log in and security functionality provided by WordPress, but you have this nightmare of trying to keep the two in sync.</li>
</ol>
<p>or</p>
<ol start="2">
<li>We build our own custom 'login' and 'register' functionality. We store the email address and password against the custom post and use that to validate them. Then also perform our own session management etc.</li>
</ol>
<p>or</p>
<ol start="3">
<li>The final option is we do infact scrap the CPT altogether and just use 'users'. Then write some kind of migration script to move the CPT's over to users.</li>
</ol>
<p>Hope that makes sense. Any thoughts/ideas most welcome.</p>

Does using heap memory (malloc/new) create a non-deterministic program? : <p>I started developing software for real-time systems a few months ago in C for space applications, and also for microcontrollers with C++. There's a rule of thumb in such systems that <strong>one should never create heap objects</strong> (so no malloc/new), because it makes the program <strong>non-deterministic</strong>. I wasn't able to verify the correctness of this statement when people tell me that. So, <strong><em>Is this a correct statement?</em></strong></p>
<p>The confusion for me is that as far as I know, determinism means that running a program twice will lead to the exact, same execution path. From my understanding this is an issue with multithreaded systems, since running the same program multiple times could have different threads running in different order every time.</p>

for (Model* name in firstArry){
NSLog(@"%@",name.name);
}
} else {
NSLog(@"second arry is empty");
}
}
I want to Filter the firstArry with the given filterWord and get a new array with the object wich they name property contains it, how to do it and how dose it work ?

Why doesn't Python return an error for string assignment using replace in a for loop? : <p>In the following example, I would have expected an error saying that string assignment is not possible because strings are immutable. Instead, the loop returns the original string.</p>
<pre><code>a = "AECD"
for i in a:
if i == "E":
a.replace(i, "B")
print(a)
</code></pre>
<p>Is replace not essentially trying to do the same thing as a[1] = "B"? Does this have to do with creating a new object with assignment versus modifying an existing one with replace?</p>

What is the maximum scrape_interval in Prometheus : <p>I used Prometheus to measure business metrics like:</p>

How do i generate a random number that only shows up Once? : <p>I'm trying to generate up to 5 numbers between 0-4 and doesn't re generate the same number more than once. The program will stop after three attempts, therefore the random numbers generated should read 4,3,2 and not 4,3,4(For example).</p>
<p>I've created an array with 5 string elements in it. at least 3 of the strings in the array will be displayed on a label when the button is clicked 3 times. After the button is clicked 3 times, the app will come to an end. However, the issue is that some of the strings in the array keeps repeating itself each time the button is clicked.
I found a method that prevents the number from repeating (1,3,1) instead of (1,1,3) for eg. But in my case i do not want a number to be generated once it was already generated. For eg. (1,3,4) instead of (1,3,1) where the (1) is re-generated.</p>
<pre><code>var fruits: [String] = ["Apple", "Mango", "Cherry", "Strawberry", "Blueberry", "Banana"] // fruits to be displayed in the label
func randomizeNum() -> UInt32 {
var randomNumber = arc4random_uniform(UInt32(fruits.count))
while previousNumber == randomNumber {
randomNumber = arc4random_uniform(UInt32(fruits.count))
}
displayLbl.text = fruits[Int(randomNumber)]
previousNumber = randomNumber
print("the random num is \(randomNumber)") // This prints for example 5, 1, 5. Need it to print only numbers that's not yet displayed with 3 attempts.
return randomNumber
}
</code></pre>
<p>I expect the output of this function to generate a random number like 0,4,1 but it generates 5,1,5 or 0,4,0 where the (0) is re-generated again.</p>

How can I use Rails 5.2 credentials in capistrano's deploy.rb file? : <p>I've just updated my Rails app to 5.2, and configured it to use the new <code>config/credentials.yml.enc</code> file.</p>
<p>When I try to deploy, I get this error:</p>
<pre><code>NameError: uninitialized constant Rails
/Users/me/Documents/project/config/deploy.rb:27:in `<top (required)>'
</code></pre>
<p>That's pointing to this line in my <code>config/deploy.rb</code> file:</p>
<pre><code>set :rollbar_token, Rails.application.credentials[:rollbar_token]
</code></pre>
<p>So it appears that while capistrano is running, it doesn't have access to <code>Rails.application.credentials</code>.</p>
<p>How are you all handling this? I've got some ideas...</p>
<ul>
<li>Set this one variable as an <code>ENV</code> variable
<ul>
<li>I don't love how this separates/customizes this one setting</li>
</ul></li>
<li>Somehow make it so capistrano has access to <code>Rails.application.credentials</code>
<ul>
<li>I don't know if this is a good idea or if there are other things I need to be aware of if I go this route</li>
</ul></li>
<li>Remove deploy tracking in rollbar
<ul>
<li>🤷♂️</li>
</ul></li>
</ul>

Differences between using Lambda Expresions and without using it? : Could someone explain my the differences between methods using lambda expresions and without using it ?
On the example :
Function<Double, Double> function;
public void methodCounting() {
this.function = x -> x = x + 2;
}
public void methodCounting(double x) {
x = x + 2;
return x;
}
What do we gain ?

How to merge two dataframes in Spark Hadoop? : I am trying to join two dataframes.
data: DataFrame[_1: bigint, _2: vector]
cluster: DataFrame[cluster: bigint]
result = data.join(broadcast(cluster))
The strange thing is, that all the executors are failing on the joining step.
I have no idea what I could do.
The data file is 2.8 gb on HDFS and the cluster data only 5 mb.
The files are read using Parquet.

How can i return multiple values from a function seperatly : i'm a newb, please help!
So the issue is quite simple, I need to return multiple values from a function, can anyone suggest how I do it? Code below:
<?php
abstract class Products
{
protected $name;
protected $price;
public function __construct($name, $price)
{
$this->name = $name;
$this->price = $price;
}
public function getName()
{
return $this->name;
}
public function getPrice()
{
return $this->price;
}
}
// A new class extension
class Furniture extends Products
{
protected $width;
protected $height;
protected $length;
public function getSize()
{
// return $this->width;
// return $this->height;
// return $this->length;
// return array($this->width, $this->height, $this->length);
}
}
So as far as I understand, when I return something, it will stop the function, so I understand why I cant just do return 3 times. Attempt to return an array didn't work with an error "Notice: Array to string conversion".
Could anyone please let me know how I can return all 3 of those?
