WKWebView doesn't run JavaScript when on background : <p>I noticed that sometimes when the webview is moved to background (have another view controller on top), it stops JavaScript functions execution, and executes them only when returning back to foreground.<br>
<a href="https://stackoverflow.com/questions/26514090/wkwebview-does-not-run-javascriptxml-http-request-with-out-adding-a-parent-vie">here</a> a thread with a similar issue but most of the solutions was some kind of hack, like adding the webview to the key window, or looping dummy calls to evaluateJavaScript so the webview wouldn't go to idle mode and stop JavaScript.<br>
Those solutions work btw, but I don't like them at all.<br>
I was wondering if there was a better solution for this problem, any way to configure the webView to prevent going into idle mode, or more elegant way to prioritize JavaScript.<br>
Thanks.</p>

JS - Block user from typing phone number : <p>I have a booking website like AirBnB and my users can exchange message between each other in my website.</p>
<p>I would like to block my users from exchanging telephone number and email address in these messages.</p>
<p>The way I am using is to look for 4 numeric digits together or @ and delete these before it sends the message.</p>
<p>Please, is there a better way to do it?</p>
<p>Thanks.</p>

PHP: How to know if number is in a interval of int? : <p>I have a variable of int type called <code>myNumber</code> and I need to know if it is in the interval [100, 200].</p>
<p>Example:</p>
<pre><code>if (myNumber in (100, 200)) {
echo 'Yes';
}
</code></pre>
<p>I wonder if PHP has a <code>in</code> function or similar.</p>

Remove unused css with React and Webpack : <p>I'm trying to remove unused css classes from my app using <a href="https://github.com/webpack-contrib/purifycss-webpack" rel="noreferrer">purify-css</a> for WebPack.</p>
<p>To build this project I'm usin <code>React</code>, <code>scss</code>, <code>WebPack</code> and <code>PostCss</code> to build and compile everything.</p>
<p>So far I was able to have progress, but there is something wrong and I don't know why, but the expected result isn't correct. I have a very very basic setup just to test these scenarios, so this is my index.html and app.js files (the only files I have so far):</p>
<p><strong>index.html</strong></p>
<pre><code><body>
<nav>
<a href="">home</a>
</nav>
<hr />
<div id="app"></div>
<footer class="my-other-heading"></footer>
</body>
</code></pre>
<p><strong>app.js</strong></p>
<pre><code>class App extends React.Component {
render() {
return (
<h1 className="my-other-heading">Mamamia!</h1>
);
}
}
render(<App />, window.document.getElementById("app"));
</code></pre>
<p>On the css files I'm using <a href="https://necolas.github.io/normalize.css/" rel="noreferrer">Normalize.css</a> (with a bunch of css classess) and just 3 custom classes:</p>
<pre><code>.my-class {
background-color: #CCDDEE;
}
.my-heading {
color: red;
}
.my-other-heading {
color: blue;
}
</code></pre>
<p>The expected output should contain only these classes:</p>
<pre><code>html, body, nav, a, hr, div, footer, h1, .my-other-heading
</code></pre>
<p>However it has some other classes:</p>
<pre><code>.my-heading, h2, h3, h4, [type='checkbox'] (and other similar, e.g.: [type='button']
</code></pre>
<p>Why is this happening? It's removing almost all the classes it should, but some of them are still here, and classes that are clearly not being used on the index file. I don't know if they persist because of some other declaration on the React side, but i'm refering only the src files. This is my purify-css config:</p>
<pre><code>new PurifyCSSPlugin({
paths: glob.sync([
path.join(__dirname, '..', 'src', '**/*.html'),
path.join(__dirname, '..', 'src', '**/*.js'),
]),
})
</code></pre>

How does request pass through filter even though servlet mapping is not present? : <p>I have web.xml which contains just a filter, Which maps to a specific URL pattern.
If I give a url which matches the pattern. It goes through the filter comes back and gives 404 status. I understand that this is because the there is no resource mapped in web.xml. Why would it go through the filter?</p>
<p>Can I keep a wrapper around filter response and modify the response to a meaningful one instead of giving 404?</p>

MockMvc no longer handles UTF-8 characters with Spring Boot 2.2.0.RELEASE : <p>After I upgraded to the newly released <code>2.2.0.RELEASE</code> version of Spring Boot some of my tests failed. It appears that the <code>MediaType.APPLICATION_JSON_UTF8</code> has been deprecated and is no longer returned as default content type from controller methods that do not specify the content type explicitly.</p>
<p>Test code like</p>
<pre><code>String content = mockMvc.perform(get("/some-api")
.contentType(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8))
.andReturn()
.getResponse()
.getContentAsString();
</code></pre>
<p>suddenly did not work anymore as the content type was mismatched as shown below</p>
<pre><code>java.lang.AssertionError: Content type
Expected :application/json;charset=UTF-8
Actual :application/json
</code></pre>
<p>Changing the code to <code>.andExpect(content().contentType(MediaType.APPLICATION_JSON))</code> resolved the issue for now. </p>
<p>But now when comparing <code>content</code> to the expected serialized object there is still a mismatch if there are any special characters in the object. It appears that the <code>.getContentAsString()</code> method does not make use of the UTF-8 character encoding by default (any more).</p>
<pre><code>java.lang.AssertionError: Response content expected:<[{"description":"Er hörte leise Schritte hinter sich."}]> but was:<[{"description":"Er hörte leise Schritte hinter sich."}]>
Expected :[{"description":"Er hörte leise Schritte hinter sich."}]
Actual :[{"description":"Er hörte leise Schritte hinter sich."}]
</code></pre>
<p>How can I get <code>content</code> in UTF-8 encoding?</p>

A bit of math programming. 4 colors on a grid : <p>Let's say I have a grid</p>
<pre><code>-----
| | |
-----
| | |
-----
</code></pre>
<p>And I have 4 colors, Red, Blue, Green, and Yellow. I am trying to figure out how many different combinations there can be using those colors in the each way. For instance I might have:</p>
<pre><code>BR BR BY BY
GY YG RG GR
</code></pre>
<p>etc.
I can use the same color more than once so it can be like this:</p>
<pre><code>BB BB BB
RR or even BR or BB
</code></pre>
<p>I tried drawing out the different combos but I always end up getting more confused the more I draw them out. I'm trying to figure this out because I'm using it for a tile system for a game I'm trying to plan out. I just need to know the different combos so I'd know how many tiles I'd need to cover everything.</p>
<p>There has to be a math way to solve this, I just can't figure it out for the life of me. </p>
<p>Thanks in advance oh math programming gods. I'll be forever in your debt</p>

How to tell DocumentDB SDK to use camelCase during linq query? : <p>Considering the document <code>{ "userName": "user1" }</code> stored in the User collection, and the following <code>User</code> class: </p>

{
public string Id { get; set; }
public string UserName { get; set; }
}
</code></pre>
<p>With the following JSON.net settings:</p>
<pre><code>JsonConvert.DefaultSettings = () =>
{
return new JsonSerializerSettings
{
ContractResolver = new CamelCasePropertyNamesContractResolver(),
};
};
</code></pre>
<p>When I query with Linq as such:</p>
<pre><code>var t = _client.CreateDocumentQuery<User>(_collection.SelfLink)
.Where(u => u.UserName == "user1").AsDocumentQuery().ExecuteNextAsync();
t.Wait();
var users = t.Result;
var user = users.FirstOrDefault();
</code></pre>
<p><code>user</code> is null. Changing the Document to have a pascal casing or the POCO to use a camel casing solves the issue. Of course I do not want any of those as I want my JSON objects and C# objects to be "standarized". </p>
<p>How can I tell the DocumentDB SDK to map my object's property names using camel casing, similar as JSON.net?</p>

How to Deserialize a list of objects from json in flutter : <p>I am using the dart package json_serializable for json serialization. Looking at the flutter documentation it shows how to deserialize a single object as follow:</p>
<pre><code>Future<Post> fetchPost() async {
final response =
await http.get('https://jsonplaceholder.typicode.com/posts/1');
if (response.statusCode == 200) {
// If the call to the server was successful, parse the JSON
return Post.fromJson(json.decode(response.body));
} else {
// If that call was not successful, throw an error.
throw Exception('Failed to load post');
}
}
</code></pre>
<p>However, I am not familiar enough with dart to figure out how to do the same for a list of items instead of a single instance.</p>

Filtering out letters only and numbers only from dictionary : So basically I have a dictionary called dict_info. Which consists different types of keys. However, I'd like to iterate through these dictionaries then filter out the ones that has ONLY letters and ONLY integers. However if they have both for instance 123456s, 123456q and 123456b. These three key has letters and integers on it. So I'd like to create a json file saving these three key-value. And I'd like to have a space inbetween digits and letters. Like 123456 s, 123456 q, and 123456 b.
So output in my json would something like with everything filtered out
output:
{
123456 q : check
123456 b : check
123456 s : check
}
def check_if_works():
dict_info = {}
dict_info['1234'] = "check"
dict_info['12456s'] = "check"
dict_info['12456q'] = "check"
dict_info['12456b'] = "check"
dict_info['123456'] = "check"
dict_info['asdftes'] = "check"
dict_info['asdftess'] = "check"
dict_info['asdftessd'] = "check"
arr = []
for key,value in dict_info.iteritems():

webpack dev server: watch arbitrary directory files and reload : <p>Is it possible to make webpack-dev-server reload whenever a specified set of arbitrary files changes?</p>
<p>Something along the lines of:</p>
<pre><code>devServer: {
watchTheseFiles: [ 'path/to/files', 'path/to/more/files' ]
}
</code></pre>
<p>And even more granularly, can I specify a regex of which files to watch?</p>
<p>I'm doing this as a bit of a hack to reload when I trigger certain changes in arbitrary files (they could be <code>.txt</code>, <code>.png</code>, whatever...)</p>
<p>At the moment, the specified paths in <code>contentBase</code> don't seem to trigger reload when files change.</p>

How can I get the raw request body in a Google Cloud Function? : <p>I need the raw request body to be able to SHA-1 digest it to validate the Facebook webhook X-Hub-Signature header that's passed along with the request to my Firebase Function (running on Google Cloud Functions).</p>
<p>The problem is that in cases like this (with a <code>Content-Type: application/json</code> header) GCF automatically parses the body using <code>bodyParser.json()</code> which consumes the data from the stream (meaning it cannot be consumed again down the Express middleware chain) and only provides the parsed javascript object as <code>req.body</code>. The raw request buffer is discarded.</p>
<p>I have tried to provide an Express app to <code>functions.https.onRequest()</code>, but that seems to be run as a child app or something with the request body already being parsed, just like when you pass a plain request-response callback to <code>onRequest()</code>.</p>
<p>Is there any way to disable GCF from parsing the body for me? Or could I somehow specify my own <code>verify</code> callback to <code>bodyParser.json()</code>? Or is there some other way?</p>
<p>PS: I first contacted Firebase support about this a week ago, but for lack of a response there I'm trying it here now.</p>

Ruby include a file? : Good day, I'm new in ruby and I'm figuring out how to include a file in ruby? I tried require and include but doesn't work.
Here's the file I'd like to insert. It only contains procedures. *Not a module*
file1.rb
if Constants.elementExist(driver, 'Allow') == true
allowElement = driver.find_element(:id, 'Allow')
allowElement.click()
sleep 1
wait.until {
driver.find_element(:id, 'Ok').click()
}
username = driver.find_element(:id, 'UsernameInput')
username.clear
username.send_keys Constants.itech_email
password = driver.find_element(:id, 'PasswordInput')
password.clear
password.send_keys Constants.itechPass
driver.find_element(:id, 'Login').click
else
username = driver.find_element(:id, 'UsernameInput')
username.clear
username.send_keys Constants.itech_email
password = driver.find_element(:id, 'PasswordInput')
password.clear
password.send_keys Constants.itechPass
driver.find_element(:id, 'Login').click
end
That file contains a long line of codes that are re-usable or repeatable in my case. Its not inside a class or a module. Its a straight forward script. And I'd like to use this file on my second file inside a module.
File2.rb
module File2
module IOS
**** insert File1.rb ****
end
end
This way, it should just read the procedures, codes of the File1.rb inside the file2.rb.
How to do this in ruby? Thank you! I hope you can help me out guys.

How to do a proper upsert using sqlalchemy on postgresql? : <p>I would like to do an upsert using the "new" functionality added by postgresql 9.5, using sqlalchemy core. While it is implemented, I'm pretty confused by the syntax, which I can't adapt to my needs.
Here is a sample code of what I would like to be able to do :</p>
<pre><code>from sqlalchemy.ext.declarative import declarative_base
Base = declarative_base()
class User(Base):
__tablename__ = 'test'
a_id = Column('id',Integer, primary_key=True)
a = Column("a",Integer)
engine = create_engine('postgres://name:password@localhost/test')
User().metadata.create_all(engine)
meta = MetaData(engine)
meta.reflect()
table = Table('test', meta, autoload=True)
conn = engine.connect()
from sqlalchemy.dialects.postgresql import insert as psql_insert
stmt = psql_insert(table).values({table.c['id']: bindparam('id'),
table.c['a']: bindparam('a')})
stmt = stmt.on_conflict_do_update(
index_elements=[table.c['id']],
set_={'a': bindparam('a')})
list_of_dictionary = [{'id':1, 'a':1, }, {'id':2, 'a':2,}]
conn.execute(stmt, list_of_dictionary)
</code></pre>
<p>I basicly want to insert a bulk of rows, and if one id is already taken, I want to update it with the value I initinaly wanted to insert.
However sqlalchemy throw me this error :</p>
<pre><code>CompileError: bindparam() name 'a' is reserved for automatic usage in the VALUES or SET clause of this insert/update statement. Please use a name other than column name when using bindparam() with insert() or update() (for example, 'b_a').
</code></pre>
<p>While it is a known issue (see <a href="https://groups.google.com/forum/#!topic/sqlalchemy/VwiUlF1cz_o" rel="noreferrer">https://groups.google.com/forum/#!topic/sqlalchemy/VwiUlF1cz_o</a>), I didn't found any proper answer that does not require to modify either the keys of list_of_dictionary or the name of your columns.</p>
<p>I want to know if there is a way of constructing stmt in a way to have a consistent behavior that does not depends on whether the keys of the variable list_of_dictionary are the name of the columns of the inserted table (my code works without error in those cases).</p>

Calculate matrix hash value : as part of my final year project, I am testing the Bouncycastle library on SHA-3.
I find the source code to calculate the hash value of a string:
String input = "hello" ;
SHA3.DigestSHA3 digestSHA3 = new SHA3.Digest256();
byte[] digest = digestSHA3.digest(input.getBytes());
System.out.println("SHA3-256 = " + Hex.toHexString(digest));
but i want to calculate the hash value of a matrix, hwo can help me?

How do you create global variables without typing "global" in each function? : I'm trying to create a global variable, but from what I know you need to type "global" in every function.
This example is in Python 2.7:
a = 10
def change():
global a
a = 2
print a
def reverse():
global a
a = 10
print a
// Output:
// 2
// 4
I'm trying to re-create the code above without the use of 'global' for every variable in every function I am going to create. Is there a better way to do this?

How to set all the values of an existing Pandas DataFrame to zero? : <p>I currently have an existing Pandas DataFrame with a date index, and columns each with a specific name.</p>
<p>As for the data cells, they are filled with various float values.</p>
<p>I would like to copy my DataFrame, but replace all these values with zero.</p>
<p>The objective is to reuse the structure of the DataFrame (dimensions, index, column names), but clear all the current values by replacing them with zeroes.</p>
<p>The way I'm currently achieving this is as follow:</p>
<pre><code>df[df > 0] = 0
</code></pre>
<p>However, this would not replace any negative value in the DataFrame.</p>
<p>Isn't there a more general approach to filling an entire existing DataFrame with a single common value?</p>
<p>Thank you in advance for your help.</p>

Mysterious number 6174 [Kaprekar Theorem] in Java : <p>In 1949 the mathematician D. R. Kaprekar, devised a process now known as Kaprekar's operation. First choose a four digit number where the digits are not all the same (that is not 1111, 2222,...). Then rearrange the digits to get the largest and smallest numbers these digits can make. Finally, subtract the smallest number from the largest to get a new number, and carry on repeating the operation for each new number.</p>
<blockquote>
<p>Let's try it out, starting with the number 2005, the digits of last
year. The maximum number we can make with these digits is 5200, and
the minimum is 0025 or 25 (if one or more of the digits is zero, embed
these in the left hand side of the minimum number)</p>
</blockquote>
<pre><code>5200 - 0025 = 5175
7551 - 1557 = 5994
9954 - 4599 = 5355
5553 - 3555 = 1998
9981 - 1899 = 8082
8820 - 0288 = 8532
8532 - 2358 = 6174
</code></pre>
<p>Now Objective is verify this theorem & find the number of iteration take to reach 6174.</p>

I need an real-life project for practice with python and Django : <p>I'm working as an apprentice for a software company in Germany. The most time I work for projects with Visual Basic for Application (Excel). For my finals I need more practice in modern languages.
I like to build a web-application for free, can be a little project or something bigger, the important thing is that I learn a few things about planing a project, speaking with the customer about the project and build the application. </p>
<p>Why Python and Django?
Aside from VBA, I learned Python for my own projects. But writing application for myself is not the same like working for a customer.</p>

How do you create reusable Animations in Angular 2 : <p>I'm playing with the Animation API, and I'd like to create a reusable animation like say sliding in content for top level router views. I managed to get through the funky meta data syntax (which is actually pretty cool once get past the crazy idea of using metadata) to get the animations mostly working.</p>
<pre><code> @Component({
//moduleId: module.id,
selector: 'album-display',
templateUrl: './albumDisplay.html',
animations: [
trigger('slideIn', [
state('*', style({
transform: 'translateX(100%)',
})),
state('in', style({
transform: 'translateX(0)',
})),
state('out', style({
transform: 'translateX(-100%)',
})),
transition('* => in', animate('600ms ease-in')),
transition('in => out', animate('600ms ease-in'))
])
]
})
export class AlbumDisplay implements OnInit {
slideInState = 'in';
...
}
</code></pre>
<p>And then assigning that to my top level element in the component:</p>
<pre><code> <div class="container" [@slideIn]="slideInState">
</code></pre>
<p>So this works, but how can I make this reusable? I don't want to stick this meta data onto every view. Since this is metadata I'm not sure how you could make this reusable.</p>

What is C++ string's default capacity? : <p>Consider the following snippet:</p>
<pre><code>string line;
line = "";
cout << line[400] << endl; //Works, random character
cout << line[20000] << endl; //Segmentation Fault
</code></pre>
<p>Looks like c++ string has a default capacity to prevent bad things happen when reaching beyond the boundary. But I can't find any more resources on this topic.</p>
