// , Can I use aiozmq with aiohttp? : // , I want to offer an asynchronous http server to clients, and use asynchronous pub-sub on an internal network of peers to which those clients connect.
It looks like the best libraries for this, respectively, are aiohttp and aiozmq:
import aiohttp
import aiozmq
If I do the above, am I already doing it wrong?
It is like using different asynchronous frameworks at once... | 0debug |

ionic change default font : <p>I know this question is asked and answered before in the links below. I want to change the default font without having to add to every css. </p>
<p>Things I have tried:</p>

<li>Changing the .tff, .eot, .woff, .svg file directly to merge my fonts and ionicons </li>
<li>Tried to implement the font by specifying it in html and css file (it works, but i want it to be default)</li>
<li>Overwrite the www/lib/ionic/fonts with open-sans font (the ionicons disappear)</li>
<li>When i use the first link (all formatting is gone, only left with text and buttons) I also tried placing the font-face on top and bottom in scss/ionic.app.scss</li>
</ol>
<p>Please help! The answers i have seen are instructions but no explanation how it works. I don't know how "ionic setup sass" works/what it does. How gulp plays a part in this.</p>

<li>I have seen people sometimes write a separate layer and compute the loss in the <code>forward</code> function. Which approach is preferable, writing a function or a layer? Why?</li>
</ol>
<p>I need a clear and nice explanation to these questions to resolve my confusions. Please help.</p>

create a php array from another multidensional array : <p>So i have the following array:</p>
<pre><code>Array
(
[22] => Array
(
[price] => 35
[qty] => 2
)
[21] => Array
(
[price] => 18
[qty] => 1
)
[49] => Array
(
[price] => 12
[qty] => 2
)
)
</code></pre>
<p>I would like to create an array like so, from the above data:</p>
<pre><code> Array
(
[0] => 35
[1] => 35
[2] => 18
[3] => 12
[4] => 12
)
</code></pre>
<p>This basically gets the "price" key value and adds it to the new array the amount of times stated in the "qty" key value. Whats the best way of achieving this?</p>

Which way is more efficient to learn data structures? : <p>My programming knowledge is up to OOP since that was the last thing we covered in the university. However, I am taking 2 courses this summer and I am constantly under pressure, but I am planning to learn data structures along the way too, to be prepared for it next semester.</p>
<p>I had two plans to learn it but I am not sure which one will be more efficient:</p>
<p>-The first one is to skim through and learn about all the types of data structures and how they are implemented.</p>
<p>-The second one is to try instead of just reading and knowing about a data structure, I will go and try to implement it. However, the drawbacks are that its slow and time consuming, so I might not be able to learn all of the data structures in time</p>

Calling javascript function with php variable as parameter from php code block : <p>I have tried all the post of stack overflow and from google but none of those seem to work for me.
This is my php code:</p>
<pre><code>echo $firstPar;
echo $secondPar;
$tab_str.="<td width=\"20%\"><a href=\"#\" onclick = \"functionCall(".$firstPar.", ".$secondPar.")\" class=\"previous round\">&#8249;</a>";
</code></pre>
<p>This is the Javascript code:</p>
<pre><code>function functionCall(firstPar, secondPar) {
alert(firstPar);
alert(secondPar);
}
</code></pre>
<p>If I am passing string values directly on the php call rather than passing the variables, I am getting the values inside the function. But the variable values are coming as null. Whereas the echo displays the variable values.</p>

Postman: How do you delete cookies in the pre-request script? : <p>All the postman cookie-management answers I've seen refer to either the browser extension (open chrome, delete cookies viz interceptor etc) or with the app, using the UI to manually manage cookies.</p>
<p>I would like to delete certain cookies in my pre-request code as part of scripting my API tests. (delete them programmatically)</p>
<p>The Sandobx API docs mention <code>pm.cookies</code> so I tried</p>
<pre><code>if (pm.cookies !== null) {
console.log("cookies!");
console.log(pm.cookies);
}
</code></pre>
<p>But the <code>pm.cookies</code> array is empty. Yet in the console, the GET call then passes a cookie.</p>
<p>There's also <code>postman.getResponseCookies</code>, which is null (I assume because we're in the pre-request section, not in the test section)</p>
<p><a href="https://stackoverflow.com/a/44639513/1916341">One answer</a> suggested calling the postman-echo service to delete the cookie. I haven't investigated this yet, but it doesn't feel right.</p>

pg.connect not a function? : <p>There appears to be a lot of documentation (e.g. <a href="https://devcenter.heroku.com/articles/heroku-postgresql#connecting-in-node-js" rel="noreferrer">https://devcenter.heroku.com/articles/heroku-postgresql#connecting-in-node-js</a>, but also elsewhere including this site) indicating that the proper method of connecting with the pg.js Node package is using pg.connect. However, I attempted (after previous problems with my actual code) to test by using the exact code shown on the aforementioned Heroku documentation:</p>
<pre><code>var pg = require('pg');
pg.defaults.ssl = true;
pg.connect(process.env.DATABASE_URL, function(err, client) {
if (err) throw err;
console.log('Connected to postgres! Getting schemas...');
client
.query('SELECT table_schema,table_name FROM information_schema.tables;')
.on('row', function(row) {
console.log(JSON.stringify(row));
});
});
</code></pre>
<p>And I got the error message "pg.connect is not a function". What is going on, and how do I fix it?</p>

iOS Swift4.0 Return Value : I am new to the swift programming so have a question on the return value.

return
}
In this case, what return value I can expect here. Since, what I know is that it should return either 0 or 1 and true or false (if I have defined bool)

C# How to Open HEIC Image : <p>I have an image upload form in ASP.NET that supports JPG/PNG/GIF and I thought it would be enough. Until Apple introduced their new HEIC image format. How do I handle that in C#?</p>
<p>Searching for C# and HEIC shows nothing in Google, so it seems this issue hasn't been addressed yet.</p>
<p>Does the .NET Framework support HEIC out-of-the-box? Probably not since it's so new. Is there any 3rd party library that supports it? I want to convert HEIC to JPG for storage.</p>

-------------------------------------------
I need to capture only string cost=399301.55 (for sample 1nd result). The good news is that the string "COST" is always at the beginning (first line) of the
result.
I try fuctions of string manipulation, but not working.
The problem is that the field "cost" is not always in the same
position (see samples). It is necessary to find what your position is
always.
The expected result is :
select (.... )
-----------------
cost=399301 (only this)

How Does Javascript if statement indentation work? : <p>How many spaces should be used for each line of if statement at the beginning of the line?
suppose we have 10 lines of nested if statements, what is the formula to determine how many lines to be used? Also can a programmer use the tab key instead to obtain proper indentation for a statement.</p>
<pre><code>if (a !== 0) {
if (b > 1) {
if (c < 1) {

CQRS event store aggregate vs projection : <p><strong>In a CQRS event store, does an "aggregate" contain a summarized view of the events or simply a reference to the boundary of those events? (group id)</strong></p>
<p>A projection is a view or representation of events so in the case of an aggregate representing a boundary that would make sense to me whereas if the aggregate contained the current summarized state I'd be confused about duplication between the two.</p>

scikit learn: train_test_split, can I ensure same splits on different datasets : <p>I understand that the train_test_split method splits a dataset into random train and test subsets. And using random_state=int can ensure we have the same splits on this dataset for each time the method is called.</p>
<p>My problem is slightly different.</p>
<p>I have two datasets, A and B, they contain identical sets of examples and the order of these examples appear in each dataset is also identical. But they key difference is that exmaples in each dataset uses a different sets of features. </p>
<p>I would like to test to see if the features used in A leads to better performance than features used in B. So I would like to ensure that when I call train_test_split on A and B, I can get the same splits on both datasets so that the comparison is meaningful.</p>
<p>Is this possible? Do I simply need to ensure the random_state in both method calls for both datasets are the same?</p>
