python asyncio add_done_callback with async def : <p>I have 2 functions: The first one, <code>def_a</code>, is an asynchronous function and the second one is <code>def_b</code> which is a regular function and called with the result of <code>def_a</code> as a callback with the <code>add_done_callback</code> function.</p>
<p>My code looks like this:</p>
<pre><code>import asyncio
def def_b(result):
next_number = result.result()
# some work on the next_number
print(next_number + 1)
async def def_a(number):
await some_async_work(number)
return number + 1
loop = asyncio.get_event_loop()
task = asyncio.ensure_future(def_a(1))
task.add_done_callback(def_b)
response = loop.run_until_complete(task)
loop.close()
</code></pre>
<p>And it's work perfectly.</p>
<p>The problem began when also the second function, <code>def_b</code>, became asynchronous. Now it looks like this:</p>
<pre><code>async def def_b(result):
next_number = result.result()
# some asynchronous work on the next_number
print(next_number + 1)
</code></pre>
<p>But now I can not provide it to the <code>add_done_callback</code> function, because it's not a regular function.</p>
<p>My question is- Is it possible and how can I provide <code>def_b</code> to the <code>add_done_callback</code> function if <code>def_b</code> is asynchronous?</p>

Is it (`?:`) typescript ternary operator : <p>I'm new to angular 2 and typescript.
I am seeing </p>
<pre><code> export interface EjectTaskOptions extends BuildOptions {
force?: boolean;
app?: string;

</code></pre>
<p>in some typescript examples. What is it (<code>?:</code>) mean ?
Is it a ternary operator (with only false condition)or some other ?</p>
<p>Thanks in advance.</p>

Need a way to refresh automatically update HTML if a text file changes : <p>I'm trying to create a non intrusive pop up that refreshes it's displayed text on the fly if the content in a local txt file has been changed. Not sure of the best method to go about this. Using html and js for this. </p>
<p>The popup reads from a txt file, pops up on screen for a few seconds then pops back down, but how could I read the file and change what is displayed automatically?</p>
<p>Any help would be appreciated.</p>

PHP Calculation - Modulus 10 check digit generation : <p>I got a problem here figuring out how to do this:</p>
<ol>
<li>I got a document no for example <code>5843</code></li>
<li>Starting with the right-most digit, multiply every other digit by 2 and 1 (For example, <code>(3x2)+(4x1)+(8x2)+(5x1)</code> and so on)</li>
<li>For every multiplication that results a number more than 9, add them digits. (For example, from the calculation on (no.2) we will get this :
<code>(6)+(4)+(16)+(5)</code>. So we got a number (16) which is more that 9. We need to add them <code>(1+6=7)</code>. Now the output will be like this : <code>(6)+(4)+(7)+(5)</code>.</li>
<li>Next, we add them <code>(6)+(4)+(7)+(5)=22</code></li>
<li>Now, we <code>divide 22 by 10</code> and get the remainder which is <code>2</code> in this case.</li>
<li>Lastly we minus the remainder with <code>10</code>. </li>
<li>So the last output will be <code>8</code></li>
</ol>
<p>Can you guys guide me on how to do this? Thank you very much !</p>

What does directly setting a pointer with a variable means? : <p>PS, I know what a pointer is and how to use one, but confused on one thing. I have already tried searching stackoverflow on this question:</p>
<pre><code>int *ptr = 20 //why illegal or seg fault or crash?
printf("%i", *ptr) // Seg Fault
printf("%i", ptr) // Output -> 20
printf("%p", &ptr) // Returns a valid address.
</code></pre>
<p>and found that, By directly assigning a value to a pointer without initializing with malloc or null, means that we are saying to the compiler, Hey CPU, Make a space in the memory to store an integer at the exact address given as value, which in this case 20. So basically saying to the compiler make a place for an INT in the ram with the address 20. By doing this we are touching system memory or illegal space.</p>
<p>But what I don't get is, </p>
<ol>
<li><blockquote>
<p>How the integer 20 can directly be referenced as a memory?</p>
</blockquote></li>
<li><blockquote>
<p>What happens when we do the same for float or char? for example float *ptr = 20.25</p>
</blockquote></li>
<li><blockquote>
<p>I tried directly converting c code to assembly with a website, for a legal and illegal pointer example, where I see that the same registers are called, same MOV operations are done, And no explicit "MAKE SPACE AT given ADDRESS" instructions were set.</p>
</blockquote></li>
<li>Lastly, What exactly happens when we declare strings by doing char
*ptr = "Hello"?</li>
</ol>
<p>I have tried every possible way to understand this, but couldn't. Can you guys point me to the right direction? Thanks ...</p>

Python Finding Missing Elements among a range of number lines. : Let's say I have a list of ranges (ie. [[1,100][102, 200], etc]]. I want to find the number of missing elements in the total range. I have a working algorithm below:
def missing(numranges):
(minimum, maximum) = (min(map(lambda x: x[0], numranges)),
max(map(lambda x: x[1], numranges)))
(count, i) = (0, minimum)
while i < maximum:
if any(j <= i <= k for j, k in numranges):
count += 1
i += 1
return maximum - minimum - count
The problem is if you have say a number line that say is like [[1, 10000], [10002, 20000]], then i goes over over all 20,000 elements and it seems to me that this is very inefficient. I'm trying to find a way to make the algorithm better but I'm a bit stumped. | 0debug |

How to have a file or string available to multiple computers and be able to changed and rewritten in C#? : <br>
I have a bit of an issue/question. <br>
I am trying to write a program that generates a specific serial number but it will be able to be accessed by multiple computers in different locations. <br>
The serial number will look something like this:<br>
(2 letters)AA(month)02(year)16(four numbers)0000<br>
Full thing: AA02160000<br>
The last 4 digits will increment by one every time the user clicks a button.
I need to be able to get that serial number from multiple computers in different locations not on the same network and edit it and rewrite it. I can't have any sort of overlap being a serial number and unique to a specific item. I also can't use a guid for the number otherwise it would be much easier.
What is the best way to do this in C#?
I have considered making a server for it but I was running into problems when trying to create directories to pull the number from because of the drive letter.
Can I access a website that is hosted on a computer in one location and have it grab that serial number and increment it and then place the new value on the website?
Quite honestly I'm spinning in circles with a million ways to do and not knowing the proper/best way to do it. A bit of help here would be much appreciated.

Getting the first paragraph of wikipedia, and storing it into a text file : I wanted to make a system in which we give something to be search onto the terminal of a Raspberry Pi and the Pi gives a voice output.
I've solved the text-to-speech conversion problem using pico TTS. Now what I wanted to do is go to the Wikipedia page of the term to be searched, and store the _first paragraph_ of the page to a text file.
For example, the result for input [Tiger][1] in Simple English should make a text file containing -
**The tiger (Panthera tigris) is a carnivorous mammal. It is the largest living member of the cat family, the Felidae. It lives in Asia, mainly India, Bhutan, China and Siberia.**

Trying to simulate a linux shell.Problems with simulating mkdir : <p>I am trying to make a c++ program to simulate a Linux shell. Nothing to fancy, just a few commands.</p>
<p>I am trying to do it like this:</p>
<p>I made a Class that tries to simulate a file system with Nodes and children.
Every node can have n children and every child has a pointer pointing to its parent.</p>
<p>The Node class looks like this:</p>
<pre><code>class Node
{
public:
Node();
Node(bool isFile);
Node(string name);
friend class Tree;
bool isFile;
vector<Node*> childs;
string name;
string text;
Node *parrent;
string names = "-";
protected:
private:
};
</code></pre>
<p>I made an addNode method that I want to use to add Nodes to my "Tree". And what I tried to do is have it like this:</p>
<pre><code>void Tree::addNode(string name,bool isFile,string pwd)
{
size_t pos=0;
string delimiter = "\\";
string token;
Node *inserter = new Node();
Node *aux;
inserter->name=name;
inserter->isFile=isFile;
aux=&this->root;
pos = pwd.find(delimiter);
token = pwd.substr(0,pos);
pwd.erase(0,pos + delimiter.length());
if((pos = pwd.find(delimiter)) == string::npos)
{
inserter->parrent=aux;
if(aux->names.find(name) == string::npos)
{
aux->childs.push_back(inserter);
aux->names.append(name);
aux->names.append(" ");
}
else
{
cout << "The directory already exists" << endl;
}
}
else
{
while((pos = pwd.find(delimiter)) != string::npos)
{
token = pwd.substr(0,pos);
pwd.erase(0,pos + delimiter.length());
for(int i = 0; i<aux->childs.size(); i++)
{
if(aux->childs[i]->name.compare(token))
{
aux=aux->childs[i];
cout << token << endl;
}
}
}
inserter->parrent=aux;
if(aux->names.find(name) == string::npos)
{
aux->childs.push_back(inserter);
aux->names.append(name);
aux->names.append(" ");
}
else
{
cout << "The directory already exists" << endl;
}
}
}
</code></pre>
<p>So, basically, every time I call this method, I want to make sure that every directory exists, and I change the pointer aux to point at the child address, and so on.</p>
<p>The first if is for making directories in the root, and what's in the while for every other directory.</p>
<p>But, due to my bad understanding of pointers, I can't see where I go wrong.
When I add nodes in the "root" node everything works fine , but when I add nodes in any children things go bad, and I can't quite put my finger on it.</p>
<p>I also have a ls and cd implemented
The ls works fine, but the cd doesn't.I try to do the same thing when checking for the existance of directories, but sometmes, even if a directory doesn't exist, if you type cd "name of directroy that you are in" it just adds to pdw even if that directory doesn't exist.</p>
<p>Here is the cd method</p>
<pre><code>bool Tree::exitsChild(string name,string pwd)
{
size_t pos=0;
string delimiter = "\\";
string token;
Node *aux;
aux=&root;
pos = pwd.find(delimiter);
token = pwd.substr(0,pos);
pwd.erase(0,pos + delimiter.length());
if((pos = pwd.find(delimiter)) == string::npos)
{
if(aux->names.find(name)!= string::npos)
{
return true;
}
else
return false;
}
else
{
while((pos = pwd.find(delimiter)) != string::npos)
{
token = pwd.substr(0,pos);
pwd.erase(0,pos + delimiter.length());
for(int i = 0; i<aux->childs.size(); i++)
{
if(aux->childs[i]->name.compare(token))
{
aux=aux->childs[i];
}
}
}
if(aux->names.find(name) != string::npos)
{
return true;
}
else
{
return false;

How to set target fragment of a dialog when using navigation components : <p>I'm showing a dialog inside a fragment using <code>childFragmentManager</code> or within an Activity using the <code>supportFragmentManager</code>, in the process I would like to set the target fragment, like this:</p>
<pre><code>val textSearchDialog = TextSearchDialogFragment.newInstance()
textSearchDialog.setTargetFragment(PlaceSearchFragment@this, 0)
</code></pre>
<p>But when running that code I get the error:</p>
<blockquote>
<p>java.lang.IllegalStateException: Fragment
TextSearchDialogFragment{b7fce67 #0 0} declared target fragment
PlaceSearchFragment{f87414 #0 id=0x7f080078} that does not belong to
this FragmentManager!</p>
</blockquote>
<p>I don't know how to access the <code>FragmentManager</code> the navigation components are using to manage the showing of the fragment, is there a solution for this?</p>

How to get started with Akka Streams? : <p>The Akka Streams library already comes with quite a <a href="http://doc.akka.io/docs/akka/2.4.2-RC1/scala/stream/index.html">wealth of documentation</a>. However, the main problem for me is that it provides too much material - I feel quite overwhelmed by the number of concepts that I have to learn. Lots of examples shown there feel very heavyweight and can't easily be translated to real world use cases and are therefore quite esoteric. I think it gives way too much details without explaining how to build all the building blocks together and how exactly it helps to solve specific problems.</p>
<p>There are sources, sinks, flows, graph stages, partial graphs, materialization, a graph DSL and a lot more and I just don't know where to start. The <a href="http://doc.akka.io/docs/akka/2.4.2-RC1/scala/stream/stream-quickstart.html#stream-quickstart-scala">quick start guide</a> is meant to be a starting place but I don't understand it. It just throws in the concepts mentioned above without explaining them. Furthermore the code examples can't be executed - there are missing parts which makes it more or less impossible for me to follow the text.</p>
<p>Can anyone explain the concepts sources, sinks, flows, graph stages, partial graphs, materialization and maybe some other things that I missed in simple words and with easy examples that don't explain every single detail (and which are probably not needed anyway at the beginning)?</p>

What is the Time Complexity of my algorithim? : This algorithm was written for LeetCode's climbing stairs problem and it ran at 20ms. I believe the time complexity is O(n), because this link https://towardsdatascience.com/understanding-time-complexity-with-python-examples-2bda6e8158a7 said O(n) is when the running time increases linearly as the size of the input gets bigger, which is what I think is going on here. I was wondering if someone could explain to me the the time complexity here and why it would be that. Any additional info on how I could get it to linear time if I'm not there already would help too.
Here is my code:
```
class Solution:
def climbStairs(self, n: int) -> int:
#n is the step I need to reach
cells = n
if cells == 0: return 1
else:
result = []
for i in range(0, 1*cells + 1):
result.append(i)
if result[i] == 0:
result[i] = 1
else:
if result[i] > 1:
result[i] = result[i-1] + result[i-2]
return result[-1]

Implements ads in libgdx game correctly : <p>I KNOW ITS LONG BUT I NEED HELP PLEASE.</p>
<p>I've been working (and struggling) with this libgdx game for the past month now and everything worked out fine but when I added interstitial ad in it then it became unexpectedly slow and the game glitches a lot..it works fine if i remove the code with the ads</p>
<p>How my game works is it goes from MenuState>>PlayState>>GameOverState>>PlayState>>GameOverState and so on..(all of the code are given below)</p>
<p>I've got a couple questions
(a) How do I get my game to work smoothly?
(b) Is there any way to show ads only in GameOverState?(I tried introducing a boolean and a 'if' statement on the ad but failed)
(c)How do i dispose my assets more effeciently?(They don't dispose if the classes are called too fast repeatedly)</p>
<p>If you require any more information about it, do let me know and I would be happy to do so..</p>

get { return empAge; }
set { empAge = value; }

<p>I actually know how properties works, but just need to find an easy way to understand why this sugar syntax work in this way.</p>
<p>So I used to think the <code>int</code> keyword between <code>public</code> and <code>age</code> is the return type of the getter, but what about the setter? obviously the setter return void which doesn't match the return type of int?</p>

Difference between creating ViewModifier and View extension in SwiftUI : <p>I'm trying to find out what is practical difference between these two approaches. For example:</p>
<pre><code>struct PrimaryLabel: ViewModifier {
func body(content: Content) -> some View {
content
.padding()
.background(Color.black)
.foregroundColor(Color.white)
.font(.largeTitle)
.cornerRadius(10)
}
}
extension View {
func makePrimaryLabel() -> some View {
self
.padding()
.background(Color.black)
.foregroundColor(Color.white)
.font(.largeTitle)
.cornerRadius(10)
}
}
</code></pre>
<p>Then we can use all of them following way:</p>
<pre><code>Text(tech.title)
.modifier(PrimaryLabel())
Text(tech.title)
.makePrimaryLabel()
ModifiedContent(
content: Text(tech.title),
modifier: PrimaryLabel()
)
</code></pre>

teacher told me not to use static/dynamic vector pointer : <p>But what are those exactly? Is...</p>
<pre class="lang-cpp prettyprint-override"><code>vector<float> Vec;
Vec.push_back(2);
</code></pre>
<p>a pointer? If so, what other options can I use instead if I want to implement lists/vectors/arrays.</p>
<p>And for my own information: Are pointers a bad way to code or kinda outdated? </p>

Improve Lombok @Data Code Coverage : <p>I am writing unit tests for my project and am trying to achieve at least 80% code coverage. Problem is that I am using lombok's <code>@Data</code> annotation for generating getters and setters and when I run my unit tests, all those getters and setters along with other methods like <code>toString</code>, <code>equals</code>, <code>hashcode</code> etc are missed and my code coverage takes a hit. Is there any workaround for this. I have been searching a lot about this but haven't been able to find anything which could help out. Any help on this would be appreciated.</p>
<p>I am using Eclemma for code coverage analysis.</p>

How to create a variable that library code can use and a user can set? : <p>1) I want to use variable <code>n_threads</code> inside my library code (that is distributed in shared library form on Windows and Linux) in multiple <code>.cpp</code> files.</p>
<p>2) I want to make library user to set it. </p>
<p>How to do such thing in C++?</p>
<ul>
<li>I tried global file with <code>static</code> variables - it leads to each <code>.cpp</code> file having its copy; </li>
<li>I have tried just to keep it in a namespace which leads to variable being already defined in other translation units and thus library not compiling</li>
<li>I have tried <code>external</code> (which works on Linux with <code>.so</code> and does compile on Windows MSVC14) which leads to library not compiling due to unresolved externals.</li>
</ul>
<p>What can be done to make global variable used in multiple library <code>.cpp</code> files be setable from outside (from library user code)?</p>

Eclipse - C++ - debugger terminating immediatly : [ECLIPSE] when I ran a C program, with breakpoints - it was all fine.
now I`m running a C++ program (simple cout print one), and it just "terminates" immediatly - instead of going through some of the breakpoints I put. on debug mode it doesnt even print the cout (that IS printed on a regular run).
I dont really know whats going wrong - debugger options? compiler?
thanks in advance! | 0debug |

Unit testing iOS 10 notifications : <p>In my app I wish to assert that notifications have been added in the correct format. I'd normally do this with dependency injection, but I can't think of a way to test the new <code>UNUserNotificationCenter</code> API.</p>
<p>I started to create a mock object which would capture the notification request:</p>
<pre><code>import Foundation
import UserNotifications
class NotificationCenterMock: UNUserNotificationCenter {
var request: UNNotificationRequest? = nil
override func add(_ request: UNNotificationRequest, withCompletionHandler completionHandler: ((Error?) -> Void)? = nil) {
self.request = request
}
}
</code></pre>
<p>However, <code>UNUserNotificationCenter</code> has no accessible initializers I can't instantiate the mock.</p>
<p>I'm not even sure I can test by adding the notification request and fetching the current notifications, as the tests would need to request permission on the Simulator which would stall the tests. Currently I've refactored the notification logic into a wrapper, so I can at least mock that throughout my application and manually test.</p>
<p>Do I have any better options than manual testing?</p>

Best way to add/remove class to menu element using pure JavaScript : JQuery code is very simple:

it adds `selected` class to selected menu element and removes that class from all other elements.
