Create an array of objects and initialize them differently : When creating a array of objects of a class and the number of objects in the array is only determined at runtime, how can I initialize each object in the array differently?
For example, `SimpleJob` is a class. I want to create an array of objects of `SimpleJob`, and initialize them differently
SimpleJob[] jobs = new SimpleJob[nbJobs];
for (int i = 1; i <= nbJobs; ++i)
{
jobs[i] = new SimpleJob(i, false);
}
Is it a good way?
Thanks.

Send Apple push notification from a Go appengine site : <p>I'm trying to send an Apple push notification from a Go appengine site. I'm using the <a href="https://godoc.org/github.com/sideshow/apns2" rel="noreferrer">apns2 library</a> as follows:</p>

<p>It looks like appengine expects you to use its own <a href="https://cloud.google.com/appengine/docs/go/outbound-requests" rel="noreferrer">urlfetch library</a> when sending outbound requests, so I tried setting the underlying <code>HTTPClient</code> to use that:</p>
<pre><code>client.HTTPClient = urlfetch.Client(ctx)
</code></pre>
<p>However, the response from the Apple server is now</p>
<pre><code>@@?HTTP/2 client preface string missing or corrupt. Hex dump for received bytes: 504f5354202f332f6465766963652f393935616138373035

<p>I believe the problem is that Apple push notifications <a href="https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ApplePushService.html" rel="noreferrer">require HTTP/2</a>, but urlfetch only implements HTTP/1.1.</p>

Pass JSON string via POST to PHP : <p>I have a page that is part of CRUD on which I can edit my data and send it to Update action of my php app. Basically, it is a HTML form with input fields.

<pre><code>[
{
"id": 21,
"name": "John"
},
[
{
"id": 25,
"name": "Bill"
},
{
"id": 20,

}
],
{
"id": 18,
"name": "Sally"
},
{
"id": 24,
"name": "Tom"
}
]
</code></pre>
<p>Now, how can I pass this array from javascript to my update action via POST with the rest of my form so I can store it in DB in a proper JSON format?</p>

Python - Check if a string contains multiple words : <p>I'm wondering if there was a function in Python 2.7 that checks to see if a string contains multiple words (as in words with spaces/punctuation marks between them), similar to how <code>.isalpha()</code> checks to see if a string contains only letters?</p>
<p>For example, if something along the lines of this exists...</p>
<pre><code>var_1 = "Two Words"
if var_1.containsmultiplewords():
print "Yes"
</code></pre>
<p>And then "Yes" would be the output.</p>

How can I unwrap a string in Xcode to fix error? : I'm a beginner in iOS programming, so please understand that my question will probably sound dumb for you. I am trying to make an app that the user selects an option from a tableview cell, but I get a "Value of optional type 'String?' must be unwrapped to a value of type 'String'" error. I get the error on the 5th line and line 16, both about "unwrapping an optional type".
I've tried adding a !, and searching on the internet, but I couldn't find any information that could help me fix the error.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as? DataTableViewCell
cell?.img.image = UIImage(named: arr[indexPath.row]["name"!])
cell?.lbl.text = arr[indexPath.row]["name"]
cell?.lbl2.text = arr[indexPath.row]["subject"]
cell?.lbl3.text = arr[indexPath.row]["grade"]
return cell!
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let vc = storyboard?.instantiateViewController(withIdentifier: "DetailViewController") as? DetailViewController
vc?.str = arr[indexPath.row]["name"]
navigationController?.pushViewController(vc!, animated: true)
}
I expect the program to run without errors.

How to add an existing project to TFS : <p>I have a solution with 6 projects already in TFS. Each project is in its own folder.</p>
<p>I right clicked the solution and added a new project, so the solution XML knows about my new project.</p>
<p>I checked in the solution file, but the newly added project is not listed in the source control explorer, presumably because I never checked in the files.</p>
<p>My question is how can I check in the project and ensure that the new project files go into its own folder?</p>
<p>If I right click in the root of the solution and select the new project files the "Destination source control folder" is set to the root - do I need to first create a folder in TFS which matches the name of my project folder? That seems backwards.</p>

What is address(0) in Solidity : <p>Can anyone explain to me what <code>address(0)</code> is in Solidity? I found the following in the docs but it doesn't really make sense to me:</p>
<blockquote>
<p>If the target account is the zero-account (the account with the address 0), the transaction creates a new contract. As already mentioned, the address of that contract is not the zero address but an address derived from the sender and its number of transactions sent (the “nonce”). The payload of such a contract creation transaction is taken to be EVM bytecode and executed. The output of this execution is permanently stored as the code of the contract. This means that in order to create a contract, you do not send the actual code of the contract, but in fact code that returns that code.</p>
</blockquote>

Specify a root path for imports? : <p>I'm converting my ongoing Vue.js app over to use vue-cli/Webpack and imported modules Something I'm finding rather tedious at the moment is specifying the relative paths for imports accurately. E.g. <code>import bus from '../../bus'</code>, <code>import Cell from '../Cell'</code>. Easy to make a mistake. </p>
<p>I'm assuming it must be straightforward enough to specify a base or root directory and specify absolute paths from that, but I can't see where one would do that. For example, in the standard vue-cli webpack setup, the code I'm working on is all in the 'src' directory, inside which I have 'components', 'mixins', etc. It would be handy if I could use <code>import xxx from 'components/xxx'</code>, <code>import yyy from 'components/a/yyy'</code>. How would I do that?</p>

sparse list of values using ranges : <p>is there a more terse way of writing</p>

Using random numbers vs hardcoded values in unit tests : <p>When I write tests, I like to use random numbers to calculate things.</p>
<p>e.g.</p>
<pre><code> func init() {
rand.Seed(time.Now().UnixNano())
}
func TestXYZ(t *testing.T) {
amount := rand.Intn(100)
cnt := 1 + rand.Intn(10)
for i := 0; i < cnt; i++ {
doSmth(amount)
}
//more stuff
}
</code></pre>
<p>which of course has the disadvantage that </p>
<pre><code>expected := calcExpected(amount, cnt)
</code></pre>
<p>in that the expected value for the test needs to be calculated from the random values.</p>
<p>If have received criticism for this approach:</p>
<ul>
<li>It makes the test unnecessarily complex</li>
<li>Less reproduceable due to randomness</li>
</ul>
<p>I think though that without randomness, I could actually:</p>
<ul>
<li>Make up my results, e.g. the test only works for a specific value. Randomness proves my test is "robust"</li>
<li>Catch more edge cases (debatable as edge cases are usually specific, e.g. 0,1,-1)</li>
</ul>
<p>Is it really that bad to use random numbers?</p>
<p>(I realize this is a bit of an opinion question, but I am very much interested in people's point of views, don't mind downvotes).</p>

python replace value if it starts with certain character : I have a following list and I am trying to replace any value which starts with ```23:``` to ```00:00:00.00```
```tc = ['00:00:00.360', '00:00:00.920', '00:00:00.060', '00:00:02.600', '23:59:55.680', '00:00:05.960', '00:00:01.040', '00:00:01.140', '00:00:01.060', '00:00:01.480', '00:00:00.140', '00:00:00.280', '23:59:59.800', '00:00:01.200', '00:00:00.400', '23:59:59.940', '00:00:01.220', '00:00:00.380']```
I am able to get what I need using regex,
```tc = [re.sub(r'(\b23:)(.*)',r'00:00:00.00', item) for item in tc]```
and it gives me expected result as per below,
```['00:00:00.360', '00:00:00.920', '00:00:00.060', '00:00:02.600', '00:00:00.00', '00:00:05.960', '00:00:01.040', '00:00:01.140', '00:00:01.060', '00:00:01.480', '00:00:00.140', '00:00:00.280', '00:00:00.00', '00:00:01.200', '00:00:00.400', '00:00:00.00', '00:00:01.220', '00:00:00.380']```
But if I use the below method without using regex, then the result is not what I expect,
```tc = [item.replace(item, '00:00:00.00') for item in tc if item.startswith('23:')]```
Result: ```['00:00:00.00', '00:00:00.00', '00:00:00.00']```
The resultant list is only with replaced items and not the whole list. How to I use the above method to get complete list?

Script editor for Google sheets (auto email function) : Google sheets - Script Editor
I need to generate an auto email reply when Column "A" is marked "Completed". The email address to send this to is in Column "I" and subject of the email needs to be data in Column "H" while the body of the email will be generic for all emails sent. This is all specific to each Row.
I have multiple script editors running, for hiding rows etc, but nothing this complex.
All data is sent in to spreadsheet from Google Forms, and will need to encompass all rows
Any help would be much appreciated.

A javascript 'let' global variable is not a property of 'window' unlike a global 'var' : <p>I used to check if a global <code>var</code> has been defined with:</p>
<pre><code>if (window['myvar']==null) ...

<p>or</p>
<pre><code>if (window.myvar==null) ...
</code></pre>
<p>It works with <code>var myvar</code></p>
<p>Now that I am trying to switch to let, this does not work anymore.</p>
<pre><code>var myvar='a';
console.log(window.myvar); // gives me a
let mylet='b';
console.log(window.mylet); // gives me undefined
</code></pre>
<p>Question:
With a global <code>let</code>, is there any place I can look if something has been defined like I could with <code>var</code> from the <code>window</code> object?</p>
<p><b>More generally</b>:<br>
Is <code>var myvar='a'</code> equivalent to <code>window.myvar='a'</code>?<br>
I hear people say that at the global level, <code>let</code> and <code>var</code> are/behave the same, but this is not what I am seeing.</p>

C++ Using enum in a Class to specify value options for user input : I'm new to the implementation of enum, but have an idea on how it's supposed to be used.
I have the bellow Allergy program to record information about an allergy provided by user input. I want to add another option for the user to select the "severity" of the allergy.

How to test components using new react router hooks? : <p>Until now, in unit tests, react router match params were retrieved as props of component.
So testing a component considering some specific match, with specific url parameters, was easy : we just had to precise router match's props as we want when rendering the component in test (I'm using enzyme library for this purpose).</p>
<p>I really enjoy new hooks for retrieving routing stuff, but I didn't find examples about how to simulate a react router match in unit testing, with new react router hooks ?</p>
