57,115,272 | How can/could/should I increment a date/time parameter in JMeter? | <p>I am sending post requests which have as parameters time and date (among others).</p>
<p>Is there a way in which after sending a request (that fills in an appointment and displays in the UI a Calendar) the time parameter would increase with 30 minutes? </p>
<p>And to cherry on the cake would be that after sending a number of requests for a certain day to be able to change the date and send another bulk of request without copy pasting and manually filling in date and time for each post?</p>
<p>basically today is 07/19/2019, I would have to send out request with time parameter that would be 00:00:00, 00:30:00 and so on. It would total 48 requests.</p>
<p>after sending those the date parameter would change into 07/20/2019 and the time parameter will continue to update the 30 minute mark.</p>
<p>I am not asking for someone to create a script for me (sure that helps), but some guidance because I find it hard to copy paste so many times.</p>
<p>Thank you in advance!</p>

57,129,668 | UI state restoration for a scene in iOS 13 while still supporting iOS 12. No storyboards | <p><em>This is a little long but it's not trivial and it takes a lot to demonstrate this issue.</em></p>
<p>I'm trying to figure out how to update a little sample app from iOS 12 to iOS 13. This sample app doesn't use any storyboards (other than the launch screen). It's a simple app that shows one view controller with a label that is updated by a timer. It uses state restoration so the counter starts from where it left off. I want to be able to support iOS 12 and iOS 13. In iOS 13 I want to update to the new scene architecture.</p>
<p>Under iOS 12 the app works just fine. On a fresh install the counter starts at 0 and goes up. Put the app in the background and then restart the app and the counter continues from where it left off. The state restoration all works.</p>
<p>Now I'm trying to get that working under iOS 13 using a scene. The problem I'm having is figuring out the correct way to initialize the scene's window and restore the navigation controller and the main view controller to the scene.</p>
<p>I've been through as much of the Apple documentation as I can find related to state restoration and scenes. I've watched WWDC videos related to windows and scenes (<a href="https://developer.apple.com/videos/play/wwdc2019/258/" rel="noreferrer">212 - Introducing Multiple Windows on iPad</a>, <a href="https://developer.apple.com/videos/play/wwdc2019/258/" rel="noreferrer">258 - Architecting Your App for Multiple Windows</a>). But I seem to be missing a piece that puts it all together.</p>
<p>When I run the app under iOS 13, all of the expected delegate methods (both AppDelegate and SceneDelegate) are being called. The state restoration is restoring the nav controller and the main view controller but I can't figure out how to set the <code>rootViewController</code> of the scene's window since all of the UI state restoration is in the AppDelegate.</p>
<p>There also seems to be something related to an <code>NSUserTask</code> that should be used but I can't connect the dots.</p>
<p><strong>The missing pieces seem to be in the <code>willConnectTo</code> method of <code>SceneDelegate</code>. I'm sure I also need some changes in <code>stateRestorationActivity</code> of <code>SceneDelegate</code>. There may also need to be changes in the <code>AppDelegate</code>. I doubt anything in <code>ViewController</code> needs to be changed.</strong></p>
<hr>
<p>To replicate what I'm doing, create a new iOS project with Xcode 11 (beta 4 at the moment) using the Single View App template. Set the Deployment Target to iOS 11 or 12.</p>
<p>Delete the main storyboard. Remove the two references in the Info.plist to Main (one at the top level and one deep inside the Application Scene Manifest. Update the 3 swift files as follows.</p>

<p>Run this under iOS 11 or 12 and it works just fine.</p>
<p>You can run this under iOS 13 and on a fresh install of the app you get the UI. But any subsequent run of the app gives a black screen because the UI restored via state restoration isn't connected to the scene's window.</p>
<p>What am I missing? Is this just missing a line or two of code or is my entire approach to iOS 13 scene state restoration wrong?</p>
<p>Keep in mind that once I get this figured out the next step will be supporting multiple windows. So the solution should work for multiple scenes, not just one.</p>

57,135,062 | Google Ads solution for PWA/SPA? | <p>I've made a single page app via Angular, and plan to also make it a progressive web app in the next few days. </p>
<p>I recently realized that Google AdSense apparently doesn't like SPAs and my application has been denied twice. My app is a tool that allows users to create, manage, and share specific content, which I believe offers a ton of value. When I was researching AdSense a while back, I definitely thought I would qualify as I didn't realize 'valuable content' specifically referred only to having a ton of words.</p>
<p>With that being said, it's 2019...is there no solution for serving Google ads on a web app that's not focused on articles, etc??
Google has tons of articles talking about how great PWAs are for users, yet it doesn't seem that they support ads for PWAs at all. I don't want to make a native mobile app, because I think a PWA that works on any device just makes more sense, so AdMob isn't an option. I've come across a few articles that indicate Doubleclick for Publishers (DFP) may be a solution, but when I try to login to that platform, it seems to be linked to my AdSense application and is either showing pending or access denied, depending on my current AdSense application status. I don't have another website that I could get approved first and then piggy back this app on that. </p>
<p>I'm also using firebase as my backed, which is why I'm pretty keen on advertising with Google as well. But obviously, if I have to go in a totally different direction to generate ad revenue with my app, I will. </p>
<p>Any insight into how I could make Google Ads work for my app or another good solution would be very much appreciated. </p>

this showed me that the if statement is functioning properly - so either the .setAvoid is not working the way I have written it, or the distance & duration calculations are not considering the setAvoid

mapObj.setAvoid(Maps.DirectionFinder.Avoid.HIGHWAYS);

<p>When I click the login button which I added to the page, following error is shown:</p>
<p><strong>Facebook has detected X isn't using a secure connection to transfer information.

<p>My app is in development mode, which should mean (according Facebook docs) that localhost redirects are allowed, but it isn't so.</p>
<p>I have also tried adding localhost to Valid OAuth Redirect URIs in Facebook developers page, but it didn't solve the problem.</p>
<p>I have managed to solve the problem partially by using ngrok following this <a href="https://www.chrisjmendez.com/2018/04/16/using-ngrok-with-facebook-oauth-login/" rel="noreferrer">tutorial</a>, but it is very buggy (sometimes doesn't work) and impractical to work with, as I often have to restart whole server and everything.</p>

57,155,164 | How to return the last element in a byte array of integers in golang | In Golang, I want to find the last element in an array of integers.
But it seems like this needs to be done manually or in such a complex way.
So if I have a list of 0.0.1, 0.0.2, 0.0.3 I just want 0.0.3 to be returned.
Every time I try to return the last element the console returns
```
%!(EXTRA uint8=10)
```
Which I assume means I need to convert a byte array to a slice?
WHY DOES THIS GOT TO BE SO COMPLEX? IN JAVASCRIPT I CAN JUST DO `pop()`
Here's my code:
```
cmd := exec.Command("git", "tag")
out, err := cmd.CombinedOutput()
if err != nil {
log.Fatalf("cmd.Run() failed with %s\n", err)
}
fmt.Printf("Variable Type:\n%s\n", reflect.TypeOf(out))
fmt.Printf("Variable:\n%s\n", (out))
slice := out[0:len(out)]
releaseVersion := slice[len(slice)-1]
fmt.Printf("release version:", releaseVersion)
```
Here's the output:
```
Variable Type:
[]uint8
Variable:
0.0.1
0.0.2
0.0.3
release version:%!(EXTRA uint8=10)
```

57,161,576 | PyTorch Binary Classification - same network structure, 'simpler' data, but worse performance? | <p>To get to grips with PyTorch (and deep learning in general) I started by working through some basic classification examples. One such example was classifying a non-linear dataset created using sklearn (full code available as notebook <a href="https://github.com/philipobrien/colab-notebooks/blob/master/Non_Linear_Data_Classification.ipynb" rel="noreferrer">here</a>)</p>
<pre><code>n_pts = 500
X, y = datasets.make_circles(n_samples=n_pts, random_state=123, noise=0.1, factor=0.2)
x_data = torch.FloatTensor(X)
y_data = torch.FloatTensor(y.reshape(500, 1))
</code></pre>
<p><a href="https://i.stack.imgur.com/w20Tb.png" rel="noreferrer"><img src="https://i.stack.imgur.com/w20Tb.png" alt="enter image description here"></a></p>
<p>This is then accurately classified using a pretty basic neural net</p>
<pre><code>class Model(nn.Module):
def __init__(self, input_size, H1, output_size):
super().__init__()
self.linear = nn.Linear(input_size, H1)
self.linear2 = nn.Linear(H1, output_size)
def forward(self, x):
x = torch.sigmoid(self.linear(x))
x = torch.sigmoid(self.linear2(x))
return x
def predict(self, x):
pred = self.forward(x)
if pred >= 0.5:
return 1
else:
return 0
</code></pre>
<p>As I have an interest in health data I then decided to try and use the same network structure to classify some a basic real-world dataset. I took heart rate data for one patient from <a href="https://physionet.org/physiobank/database/bidmc/" rel="noreferrer">here</a>, and altered it so all values > 91 would be labelled as anomalies (e.g. a <code>1</code> and everything <= 91 labelled a <code>0</code>). This is completely arbitrary, but I just wanted to see how the classification would work. The complete notebook for this example is <a href="https://github.com/philipobrien/colab-notebooks/blob/master/Basic_Heart_rate_Classification.ipynb" rel="noreferrer">here</a>.</p>
<p><a href="https://i.stack.imgur.com/6izzI.png" rel="noreferrer"><img src="https://i.stack.imgur.com/6izzI.png" alt="enter image description here"></a></p>
<p>What is not intuitive to me is why the first example reaches <strong>a loss of 0.0016 after 1,000 epochs</strong>, whereas the second example only reaches <strong>a loss of 0.4296 after 10,000 epochs</strong></p>

#include <float.h>

<p>Is there some configuration issue with clang or some missing command line argument? Googling around a bit, it appears that the order of paths when including float.h is important, but this is all supposed to be handled internally by the clang driver. </p>

57,169,862 | Building numpy with ATLAS/LAPACK support | <p>I am trying to compile <code>numpy</code> v1.12 in order to get support for ATLAS/LAPACK routines. </p>

<p><strong>The setup</strong></p>
<p>I do not have admin privileges on the host(s) I am working on (a computational cluster). </p>
<p>However, the nodes offer access to <code>gcc</code> 4.7.2 and 5.3.0, <code>glibc</code> 2.17 and 2.22, and ATLAS/LAPACK libraries and headers v3.10.2 via GNU modules.</p>
<p>For compatibility reasons, I am working with a virtual environment that contains Python 2.7.16. Likewise, I am installing an older version of <code>numpy</code> for the same reason. If things work, I may explore newer versions of <code>numpy</code> but at this time, that is what I am working with. </p>

</code></pre>
<p>I am using <code>--fcompiler=gnu95</code> as the ATLAS/LAPACK libraries were compiled with GNU Fortran. I am overriding <code>CFLAGS</code> and <code>LDFLAGS</code> variables in order for the GCC toolkit to be able to compile and link properly.</p>
<p><strong>The question</strong></p>
<p>After compilation, I test the <code>numpy</code> library to see what is installed via one method:</p>

57,194,152 | Is Python `list.extend(iterator)` guaranteed to be lazy? | <h1>Summary</h1>
<p>Suppose I have an <code>iterator</code> that, as elements are consumed from it, performs some side effect, such as modifying a list. If I define a list <code>l</code> and call <code>l.extend(iterator)</code>, is it guaranteed that <code>extend</code> will push elements onto <code>l</code> one-by-one, <em>as elements from the iterator are consumed</em>, as opposed to kept in a buffer and then pushed on all at once?</p>
<h1>My experiments</h1>
<p>I did a quick test in Python 3.7 on my computer, and <code>list.extend</code> seems to be lazy based on that test. (See code below.) Is this guaranteed by the spec, and if so, where in the spec is that mentioned?</p>
<p>(Also, feel free to criticize me and say "this is not Pythonic, you fool!"--though I would appreciate it if you also answer the question if you want to criticize me. Part of why I'm asking is for my own curiosity.)</p>
<p>Say I define an iterator that pushes onto a list as it runs:</p>
<pre class="lang-py prettyprint-override"><code>l = []
def iterator(k):
for i in range(5):
print([j in k for j in range(5)])
yield i
l.extend(iterator(l))
</code></pre>
<p>Here are examples of non-lazy (i.e. buffered) vs. lazy possible <code>extend</code> implementations:</p>
<pre class="lang-py prettyprint-override"><code>def extend_nonlazy(l, iterator):
l += list(iterator)
def extend_lazy(l, iterator):
for i in iterator:
l.append(i)
</code></pre>
<h1>Results</h1>
<p>Here's what happens when I run both <em>known</em> implementations of <code>extend</code>.</p>
<hr>
<p>Non-lazy:</p>
<pre class="lang-py prettyprint-override"><code>l = []
extend_nonlazy(l, iterator(l))
</code></pre>
<pre><code># output
[False, False, False, False, False]
[False, False, False, False, False]
[False, False, False, False, False]
[False, False, False, False, False]
[False, False, False, False, False]
# l = [0, 1, 2, 3, 4]
</code></pre>
<hr>
<p>Lazy:</p>
<pre class="lang-py prettyprint-override"><code>l = []
extend_lazy(l, iterator(l))
</code></pre>
<pre><code>[False, False, False, False, False]
[True, False, False, False, False]
[True, True, False, False, False]
[True, True, True, False, False]
[True, True, True, True, False]
</code></pre>
<hr>
<p>My own experimentation shows that native <code>list.extend</code> seems to work like the lazy version, but my question is: does the Python spec guarantee that?</p>

57,204,314 | I need some vba code that copies the contents of the attachment (a word document) and inserts it into the body of the draft email | I have a program that generates a draft email with an attached letter for the user to send on to the client. Most clients don't want the letter as an attachment but want it in the body of the email. Is it possible to create a button that runs some vba that opens up the attachment of the draft email, copies the text and pastes it into the body of the email?
