Detecting irregularities or the so called outliners : <p>Hello dear boys and girls, I apologize if the question is not in the right place (talking about the right forum - stackoverflow, etc.)</p>
<p>I can use python and R on a semi-intermediate level...
I have been wondering for a while about the topic of this question:</p>
<ol>
<li>If i have a data set that i can build a statistical model on then all is well. I build the model, test it, test it again, make a score card and poof.</li>
<li>I want to know... Is there a way of (theoretically or even practically) to detect irregularities/outliners in data without a previous data set that (for example) you can build a statistical model on. I mean a way that excludes checking 400 million records and flagging the irregs as such and then doing something productive.</li>
</ol>
<p>Is this possible? Identifying such things without a preset solid definition for the given data set? Lets take accounting records for example. I have "x" amount of records and i want to detect any records that are not "natural" for the data set. is there a way to code a system that does that - given that you don't have prior data with such records flagged as not normal?</p>

How to Map a specific element of a list : How can I map a list till I find a element?
Any suggestion?
Example:
List = [1,2,3,4,5,6]
I want to map only if I find 3 and stop there.
function x = x*2
Output:
List = [1,2,6,4,5,6] | 0debug |

jQuery, .load, javascript, (prevevent scroll up), XMLHttpRequest, .innerHTML, CSS/JS NOT WORKING : When using this code no CSS/Javascript works (It just loads the HTML):

xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
var text = xhttp.responseText;
document.getElementById("content").innerHTML = "";
document.getElementById("content").innerHTML = text;
}
}
xhttp.open("GET", "?x=test&limit=" + limit, false);
xhttp.send();
*/
}
When using jQuery CSS/Javascript works, now the problem is that the page scrolls up when loading the content.
$('#content').load('?x=test&limit=" + limit);
What i want is a way to load an URL to a DIV, where CSS and Javascript works.
And like .innerHTML i want to load the content without scrolling to the top.
Hope for help, yesterday i googled for 6-8 hours, and im a google-fu guru =)

<p>I get that this causes the a new function to be created with each render. And that it could trigger unneeded re-renders because the child component will think it's props have changed.</p>
<p>But my question is this, how else can one pass parameters to an event handler inside a loop:</p>
<pre><code>customers.map( c => <Btn onClick={ () => this.deleteCust(c.id) } /> );

How to use classes in android : <p>im not new to programming and to android at all, but I have a little problem. I can make some good apps work, but I fell like im not working very good with the classes issue. For Example, if I have a background that moving , or any other animations, I will always put the code in the MainActivity. And I have seen some projects which have class named "background animation" or "missle falling class" that making some missles fall in the background . So the problem is that I will always put the code in the main activity. I know how to use classes, but this is a problem for me, i dont know when to put the code on another class or not. thank you . I will tell more so you will understand. When you making a game in android, you probably will have class for your "game" or game class, and I dont have one. I know I need it, but I have no idea how to connect the whole game to one class. Did you understand ? thank you !!</p>

Retrieving random item in array returns 'undefined' : <p>I used Math.random() to generate a random number between 1 and however many items are in the array <code>availableNumbers()</code></p>
<p>However, when the document's innerHTML is updated with this, suggestedNumber resolved to undefined,</p>
<p>I tried subtracting 1 from randomNumber but that did not make a difference.</p>
<p>I have checked the W3 documentation and it looks like this is implemented correctly...</p>
<p>How would one best go about retrieving a random item from an array? Is there a better implementation than what I sought to implement?</p>
<pre><code>var availableNumbers = ["0", "911"];
function numberSuggestion() {
var randomNumber = Math.random() * availableNumbers.length -1;
var suggestedNumber = availableNumbers[randomNumber];
document.getElementById("suggestion").innerHTML = "How about dialing " + suggestedNumber + "? Don't like this number? Click the button above again!";
}

javascript get random element from array : The thing is that the post title is not the actual thing what I need. The answer I need is much more harder.
Ok, so I have very big array of numbers in javascript:
[1, 1.01, 1.02, 1.03, ..., 1.99, 2, ..., 9.98, 9.99, ..., 299.99, 300]
And what I need is to get one of them using random segment. So basically I need random number but the catch is that I need to get random using the lottery style. So the chance to get "1" will be 30 000 (very hight) and the chance to get 1.01 will be 29 999. But the chance to get 300 will be very low according of all numbers in this array.
I hope you will understand the problem and will help me to solve this. As I have mentioned before, this have to be made 100% randomly and I have no idea how to make it.. | 0debug |

c++ reading an array char from a text file : I got a function :
uintptr_t FindPattern(HANDLE hProcess, uintptr_t start, uintptr_t end, char *pattern, char *mask);
when i call it like this, it's OK :
uintptr_t found = FindPattern(hProcess, START, END, "\x89\x41\x24\xE9\x00\x00\x00\x00\x8B\x46\x00\x6A\x00\x6A\x00\x50\x8B\xCE\xE8", "xxxx????xx?xxxxxxxx");
now, i'm storing pattern and mask in a text file, reading these as string and convert them back to char, but it's no more working :
char* tmp1 = new char[pattern.length() + 1];
strncpy(tmp1, pattern.c_str(), pattern.length());
tmp1[pattern.length()] = '\0';
char* tmp2 = new char[mask.length() + 1];
strncpy(tmp2, mask.c_str(), mask.length());
tmp2[mask.length()] = '\0';
uintptr_t found = FindPattern(hProcess, START, END, tmp1, tmp2);
delete[] tmp1;
delete[] tmp2;
for what i see, mask is OK but i got a problem with pattern.
i think i have to suppress "\" or maybe doubling them ("\\\").

Angular Materials: Can you disable the autocomplete suggestions for an input? : <p>I'm just using simple input containers such as this</p>

<input md-maxlength="30" name="name" ng-model="name" />
</md-input-container>

<p>The input field is suggesting previously entered values which is obscuring some important interface elements and also really not necessary in my case. Is there any way to disable the suggestions?</p>

How does password manager rechecks the password as salt value is random? : <p>I am relatively new to LINUX, so I am having trouble understanding one concept related to pass in LINUX.</p>
<p>I learnt that UNIX stores my passwords by hashing it, and storing along with the randomly generated salt value.</p>
<p><code>Salt value is nothing but a random data that's generated to combine with the original password, inorder to increase the strength of the hash.</code></p>
<p>So now lets say I want to login again using my password, the manager calculates the hash but from where will it bring the same salt for checking the result with the password database?</p>

<p>So here's my code so far, and the assignment is to write an iterative and a recursive function that adds five positive integers under 20 together (the inputs that the prof wants us to test have a bunch of negatives and integers above 20). However, when I try and run what I have so far I get a segmentation fault after inputting the elements of the array. I'm not exactly sure what exactly is going wrong here, so any hints or clues would be much appreciated. Thanks. </p>

Can someone explain how I made this code work? : <p>So we had a lab activity a few days ago where we had to print the number of letters in a word alphabetically. No duplicate printing of the same letter. For some reason, I got it to work by typing the condition if x[i] == x[i-1] but after coming home, I can't wrap my head on how I came up with this and how this works in the first place. Can someone explain to me how it worked? Even though it worked I want to know the logic behind that "if" condition. Thanks and good day.</p>

The program lets the user enter any extra items (peripherals), which shipping method they want to use, and then allows them to push buttons that calculate their total costs either with or without shipping depending on the button they push.
The problem is, when I run it, it freezes and doesn't do anything after I click either of the calculate buttons. Does anyone see anything wrong with my code that could be causing this?
Thank you.</p>

Can't connect to Docker containers on OSX : <p>I'm new to Docker, and I can't seem to connect to any containers.</p>
<p>I installed <a href="https://docs.docker.com/engine/installation/mac/" rel="noreferrer">Docker Toolbox</a>. Now I'm trying to get <a href="http://shipyard-project.com/docs/deploy/automated/" rel="noreferrer">Shipyard</a> to work. I followed the steps inside of a Docker Quickstart Terminal. The instructions say:</p>
<blockquote>
<p>Once deployed, the script will output the URL to connect along with credential information.</p>
</blockquote>
<p>The Shipyard installer ended with:</p>
<pre><code>Shipyard available at http://10.0.2.15:8080
Username: [elided] Password: [elided]
</code></pre>
<p>However, I went to <code>http://10.0.2.15:8080</code> on my browser and it didn't connect.</p>
<p>In another Docker Quickstart Terminal, I did a <code>docker ps</code> to see what the container was and to get its IP Address and I got:</p>
<pre><code>$ docker inspect a4755 | grep IPAddress
"SecondaryIPAddresses": null,
"IPAddress": "172.17.0.8",
"IPAddress": "172.17.0.8",
</code></pre>
<p>I'm not sure why the IP was different, but I tried to connect to <code>http://172.17.0.8:8080</code> and this didn't work either. <code>http://localhost:8080</code> also failed.</p>
<p>This also happened when I tried to run <a href="https://github.com/rehabstudio/docker-gunicorn-nginx" rel="noreferrer">docker-gunicorn-nginx</a> - everything started, but I couldn't connect to the machine.</p>
<p>What gives?</p>

In this way i get/create collection at database
DBCollection collection = db.getCollection("shop");
BasicDBObject dbObject = new BasicDBObject();
dbObject.put("shop", shop.createCategoriesWithGoods());
collection.insert(dbObject);
But this way doesn't help me to get category as

Force Flutter navigator to reload state when popping : <p>I have one <code>StatefulWidget</code> in Flutter with button, which navigates me to another <code>StatefulWidget</code> using <code>Navigator.push()</code>. On second widget I'm changing global state (some user preferences). When I get back from second widget to first, using <code>Navigator.pop()</code> the first widget is in old state, but I want to force it's reload. Any idea how to do this? I have one idea but it looks ugly:</p>
<ol>
<li>pop to remove second widget (current one)</li>
<li>pop again to remove first widget (previous one)</li>
<li>push first widget (it should force redraw)</li>

Accessing a size_type of vector inside a structure : I have got a structure

for (vector::size_type i = 0; i < str.values.size(); i++) {
and
for (size_t i = 0; i < str.values.size(); i++) {
but I know that it should be done somehow like here but I have got an error. How to get this size?
for (str::values::size_type i = 0; i < str.values.size(); i++) {
And I know that I could use
for (auto i : str.values)

Canvas in Google Chrome 61.0.3163.79 are too slow on Linux : <p>I recently updated Google Chrome to the 61.0.3163.79 version and it was suddenly very slow with canvas. This issue only appears on Linux.</p>
<p>For exemple, <a href="http://vincentgarreau.com/particles.js/" rel="noreferrer">http://vincentgarreau.com/particles.js/</a> was 60 FPS before the Chrome update, and now it run at 2 FPS.</p>
<p>What's wrong with the new Google Chrome update ?</p>
<p>P.S: Chromium 61.0.3163.79 works fine on my computer.</p>

Short way to write or in python : <p>I have this code:</p>
<p>table is a list.</p>
<pre><code>if 'ping' in table or 'pong' in table:
# Do something here
</code></pre>
<p>Is there a shorter way to write this?
I don't want to have table duplicated in the if statement.</p>

How can I store user input in arrays and then print them out? : <p>I am a beginner programmer and I am making a little application for practice.</p>
<p>You enter your budget, then you add an expense(name, amount)
and it subtracts and tells you your current budget.</p>
<p>I want to make it so you can see all of your expenses after each execution.</p>
<p>I have tried to make for loops that store the names of the expenses and then print them.
But I am doing something wrong :/.</p>
<p>Sorry for my bad English, I am from Croatia!</p>
<p>Here is some beginner ugly code.</p>
<pre><code> int length = 0;
String[] listOfNames = new String[length];
boolean active = true;
int budget = 0;
Scanner input = new Scanner(System.in); //user input
System.out.println("Enter current budget in HRK");
int enteredAmount = input.nextInt(); //user input for budget
budget = enteredAmount;
while(active)
{
System.out.println("Current budget is " + budget + " HRK");
System.out.println("Enter expense name and amount");
System.out.println("Name: ");
String name = input.next(); //name of expense
for(int i=0; i<listOfNames.length;i++){ //adds entered expense names to array
listOfNames[i] = name;
length++;
}
System.out.println("Amount: ");
int enteredAmount1 = input.nextInt();
budget -= enteredAmount1; // subtracts the budget from the users input
System.out.println("Expense: " + name + ", Amount: " + enteredAmount1); // prints final result
for(int j=0; j<listOfNames.length; j++) // prints stored strings in array
{
System.out.println(listOfNames[j]);
}
}

Why dict.get return a tuple with None? : <p>I have a dict:</p>
<pre><code>book = {
'id': 2,
'author': 'J.R.R. Tolkien',
'pages': 332,
'title': 'Fellowship',
}
err_msg='No such key'
a = book.get('signature'),err_msg
print(a)
</code></pre>
<p>Result is:</p>
<blockquote>
<p>(None, 'No such key')</p>
</blockquote>
<p>Why I receive the tuple as a result instead of 'No such key'?</p>
<p>In the documentation:</p>
<p><strong>get(key[, default])</strong></p>
<p><em>Return the value for key if key is in the dictionary, else default. If default is not given, it defaults to None, so that this method never raises a KeyError.</em></p>
