<p>Warning: Please mind my English grammar and note that I had to copy and paste the code and make it look neat(because the whitespace was terrible when I pasted it in). That could explain why it might look sloppy without whitespace.</p>
<p>Another sidenote is that this is not a duplicate because the other questions on this topic did not awnser my question nor did it help me solve my programming problem. My problem takes a statement into object oreinted programming(with classes and methods) and uses switch statements. The previous questions on this topic has unique problems that I did not face, and by asking this I am trying to resolve my issue, not a general issue on the error, but what I did wrong in my code.</p>

"next": "http://example.com/articles?page[number]=4&page[size]=1",
"last": "http://example.com/articles?page[number]=1&page[size]=1"
}
}
```
Suppose I'm getting this Json as response from a web server, is there a way somehow to use [reduce()](https://www.w3schools.com/jsref/jsref_reduce.asp) method here?
I tried like:
```
$.ajax({
url:"http://...",
type: "GET",
headers:{"application/vnd+json"},
success: function(data){
var r = data.cells.reduce(function(array, object) {
return array.concat(object.type);
}, {});
console.log(r);
}
)};
```
Is it possible at all to use reduce here? My task is to use reduce function for the given Json my AJAX is ok? | <javascript><ajax> | 2019-11-06 21:28:46 | LQ_EDIT |

58,749,281 | What is the difference betwwen the older alloctaor::construct and the new one and explicit constructor? | <p>As I know <code>std::allocator<T>::construct</code> takes only two parameters on older version of C++; the first is a pointer to raw, un-constructed memory in which we want to construct an object of type <code>T</code> and the second one is a value of element type to initialize that object. So the copy-constructor is invoked:</p>
<pre><code>struct Foo {
Foo(int, int) { cout << "Foo(int, int)" << endl; }
/*explicit*/ Foo(int) { cout << "Foo(int)" << endl; }
Foo(const Foo&) { cout << "Foo(const Foo&)" << endl; }
};
int main(int argc, char* argv[]) {
allocator<Foo> a;
Foo* const p = a.allocate(200, NULL); // second parameter is required on C++98 but on C++11 it is optional
// Foo* const p = a.allocate(200); // works fine on C++11 but not on C++98
a.construct(p, 5, 7); // works on C++ 11 and up but not C++98
a.construct(p, 10);// works on both
a.destroy(p);
a.destroy(p + 1);
a.deallocate(p, 200);
std::cout << std::endl;
}
</code></pre>
<ul>
<li><p>Why on C++98 <code>a.construct(p, 10)</code> calling the copy constructor but on C++11 and above is calling just the constructor that takes an integer?</p></li>
<li><p>Does this mean on C++ 11 because of some Copy-elision optimization even if the constructor <code>Foo(int)</code> is <code>explicit</code> works on such call: <code>a.construct(p, 5)</code> works on C++11 even the constructor is <code>explicit</code> what I am sure of is it doesn't works on C++98 if <code>Foo(int)</code> is <code>explicit</code>.</p></li>
<li><p>If so then if I compile that statement with some sort of disabling <code>copy-elision</code> optimization will cause the compiler fail? Thank you.</p></li>

58,785,802 | 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>

58,786,695 | How to address 'OSError: libc not found' raised on Gunicorn exec of Flask app inside Alpine docker container | <p>I'm working on a Flask application based on the Microblog app from Miguel Grinberg's mega-tutorial. Code lives here: <a href="https://github.com/dnilasor/quickgig" rel="noreferrer">https://github.com/dnilasor/quickgig</a> . I have a working docker implementation with a linked MySQL 5.7 container. Today I added an Admin View function using the Flask-Admin module. It works beautifully served locally (OSX) on Flask server via 'flask run' but when I build and run the new docker image (based on python:3.8-alpine), it crashes on boot with a <code>OSError: libc not found</code> error, the code for which seems to indicate <a href="https://github.com/benoitc/gunicorn/blob/438371ee90b9676336a44c7abaeb30ee7fc57a5c/gunicorn/socketfromfd.py#L26" rel="noreferrer">an unknown library</a></p>
<p>It looks to me like Gunicorn is unable to serve the app following my additions. My classmate and I are stumped!</p>
<p>I originally got the error using the python:3.6-alpine base image and so tried with 3.7 and 3.8 to no avail. I also noticed that I was redundantly adding PyMySQL, once in requirements.txt specifying version no. and again explicitly in the dockerfile with no spec. Removed the requirements.txt entry. Also tried incrementing the Flask-Admin version no. up and down. Also tried cleaning up my database migrations as I have seen multiple migration files causing the container to fail to boot (admittedly this was when using SQLite). Now there is only a single migration file and based on the stack trace it seems like the <code>flask db upgrade</code> works just fine.</p>
<p>One thing I have yet to try is a different base image (less minimal?), can try soon and update this. But the issue is so mysterious to me that I thought it time to ask if anyone else has seen it : )</p>
<p>I did find <a href="https://bugs.python.org/issue28134" rel="noreferrer">this socket bug</a> which seemed potentially relevant but it was supposed to be fully fixed in python 3.8.</p>
<p>Also FYI I followed some of the advice <a href="https://github.com/miguelgrinberg/microblog/issues/49" rel="noreferrer">here</a> on circular imports and imported my admin controller function inside <code>create_app</code>.</p>

58,787,059 | why my python cannot read files on my desktop | I'm new here and in python. There are 2 questions I'd like to ask:
1) I'm reading a .dat file on my desktop into my spider, but it shows No such file or directory: 'C:\\Desktop\\movies.dat', but if I put the file into the default folder, 'C:\\Users\\User\\.spyder-py3\\movies.dat', it can read the file successfully. I thought that python3 can file the path in the quotes no matter if it is a default folder or not.
2) I've been reading some python books and in every beginning of each book, there is a chaper introducing Ipython and Jupyter orsomething like that, I don't quite understand what's the difference between, like, Anaconda, Spider, Jupyter notebook and Ipython.

<p>Nothing worked.</p>
<p>After searching for a solution, I think the problem is that I have duplicated dependencies. So I've tried the following:</p>
<pre><code>
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation ('com.android.support:appcompat-v7:22.2.1'){
exclude module: 'support-v4'
}
implementation ('com.android.support:design:22.2.1')
implementation 'com.github.frankiesardo:linearlistview:1.0.1@aar'
}
</code></pre>
<p>And this:</p>
<pre><code>
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation ('com.android.support:design:22.2.1'){
exclude module: 'support-v7'
}
implementation 'com.github.frankiesardo:linearlistview:1.0.1@aar'
}
</code></pre>
<p>I still get the same error.</p>
<p>Could anyone please tell me what I'm doing wrong?
Thank you in anticipation. :)</p>

58,793,066 | How to summarize the employees by net revenue and not order date? | 8. The sales director would like to reward the employees with net sales over $150,000 for the years 2015 and 2016 combined. The Sales Manager would like the resulting query to display the following columns: Employee ID, Employee Name (First and Last as one field), Total Net Sales per employee. (Both years should be combined into one number.) [enter image description here][1]Sort largest to smallest.
We cannot figure out how to combine the revenues by the employees.
select o.EmpID, EmpFName + ' ' + EmpLastName as "Employee Name",
sum((salesunitprice*quantitysold)-((salesunitprice*quantitysold)*ItemDiscount)) as "Net Sales"
from EMPLOYEE e inner join ORDERS o on e.EmpID=o.EmpID

inner join SALES_INVOICE_DETAIL sd on si.SalesInvoiceID=sd.SalesInvoiceID
group by o.EmpID, EmpFName + ' ' + EmpLastName, OrderDate
having OrderDate between '2015-01-01' and '2016-12-31'
order by [Employee Name]
I expected the output to be the total per employee, but it is broken out by individual order dates instead of summing the total net sales per employee. Please help!

58,802,767 | No “Proceed Anyway” option on NET::ERR_CERT_INVALID in Chrome on MacOS | <p>I try to get my local development in Chrome back running, but Chrome prevents that, with the message that the certificate is invalid. Even though it could not be the date of the certificate, as you can see in the screenshot of it:</p>
<p><a href="https://i.stack.imgur.com/EDHew.png" rel="noreferrer"><img src="https://i.stack.imgur.com/EDHew.png" alt="enter image description here"></a></p>
<p>I just wonder why there is no advanced > option to proceed anyway to see the website and being able to locally develop the app.</p>
<p>A few more things to mention:</p>
<ul>
<li>The local development runs on
<a href="https://local.app.somecompany.com:4200/" rel="noreferrer">https://local.app.somecompany.com:4200/</a>. It can't be just localhost,
because otherwise our authentication http-only cookies won't work in
Chrome.</li>
<li>Therefore the host file under etc/hosts was adjusted to
point to the localhost IP adress (127.0.0.1).</li>
<li>The certificate was
generated with openssl according to this <a href="https://medium.com/@rubenvermeulen/running-angular-cli-over-https-with-a-trusted-certificate-4a0d5f92747a" rel="noreferrer">tutorial</a> and this
<a href="https://github.com/RubenVermeulen/generate-trusted-ssl-certificate" rel="noreferrer">repo</a></li>
<li>The certificate works for a colleague with the exact same
Chrome version but with a MacOS version 10.14.6 (mine right now is
MacOS 10.15.1)</li>
<li>The chrome flag(chrome://flags/#allow-insecure-localhost) does not change anything</li>
<li>Also works in firefox on my laptop.</li>
</ul>
<p>Can't find anything online that helped me to solve this so far, so I would be extremly thankful, if anyone has some more ideas what I could try!?</p>
