57,871,843 | Why is the Streamlistener reakting differently? | I'm tring to use the Streambuilder in cooperation with Bloc. The problem is that somehow the UI updates only when the expensive Funktions are finished. It seams that then, and only then updates are made to the stream. But I can not figure out why?
I Implemented a simple Bloc that has 4 events:
1. a Future called over the Bloc Sate Object
2. a Future called inside the Bloc
3. a Funktion called inside the Bloc
4 just using Future.delay
I'm Trying to understand why everything behaves as expectetd, but not when I use first two. My guess is I have a basic misunderstanding of the eventloop but I can not see why there should be a difference in behavior between 2 and 4 or 1 and 4

And suppose that I work on a new branch I created (named "dev") other than the master branch. And I did the add, commit, push all under this new branch and did not do any "merge". How do I do a "pull request" and what is that step supposed to accomplish beyond git add, commit, push. Does that just mean I merge "dev" to "master"?</p>

57,897,288 | UITableViewAlertForLayoutOutsideViewHierarchy error: Warning once only (iOS 13 GM) | <p>I am getting a strange error with iOS13 when performing a Segue and I can't figure out what it means, nor can I find any documentation for this error. The problem is that this seems to cause a lot of lag (a few seconds) until the segue is performed.</p>
<blockquote>
<p>2019-09-11 22:45:38.861982+0100 Thrive[2324:414597] [TableView] Warning once only: UITableView was told to layout its visible cells
and other contents without being in the view hierarchy (the table view
or one of its superviews has not been added to a window). This may
cause bugs by forcing views inside the table view to load and perform
layout without accurate information (e.g. table view bounds, trait
collection, layout margins, safe area insets, etc), and will also
cause unnecessary performance overhead due to extra layout passes.
Make a symbolic breakpoint at
UITableViewAlertForLayoutOutsideViewHierarchy to catch this in the
debugger and see what caused this to occur, so you can avoid this
action altogether if possible, or defer it until the table view has
been added to a window. Table view: ; layer = ; contentOffset: {0, 0}; contentSize: {315, 118};
adjustedContentInset: {0, 0, 0, 0}; dataSource: ></p>
</blockquote>
<p>I am using Hero but I tried disabling it and using a regular Segue and this hasn't stopped the lag.</p>
<p>The code to initiate the segue is didSelectRowAt</p>
<pre><code>func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if indexPath.section == 0 {
selectedCell = realIndexFor(activeGoalAt: indexPath)
performSegue(withIdentifier: "toGoalDetails", sender: nil)
} else if indexPath.section == 1 {
selectedCell = indexPath.row
performSegue(withIdentifier: "toIdeaDetails", sender: nil)
} else {
selectedDecision = indexPath.row
hero(destination: "DecisionDetails", type: .zoom)
}
}
</code></pre>
<p>And then none of the code in viewDidLoad or viewWillAppear from the destination VC affects this in any way (I tried commenting it all out with no difference.</p>
<p>Any idea what's causing this? I can share whatever other details are needed.</p>

57,910,231 | Problems creating custom txt names in C | I am having trouble creating custom filenames in C. The goal is to use custom files to print data to for separate entities. My current code for the printing to the file is:
```
void output(int t, double rx[], double ry[], double rz[], double vx[], double vy[], double vz[], double fx[], double fy[], double fz[])
{
for(int i = 0; i < Npart; i++)
{
char name[20];
sprintf(name, "Part_%d.txt", i);
fptr = fopen(name, "a");
fprintf(fptr, "%4d, %10.2e, %10.2e, %10.2e, %10.2e, %10.2e, %10.2e, %10.2e, %10.2e, %10.2e\n", t, rx[i], ry[i], rz[i], vx[i], vy[i], vz[i], fx[i], fy[i], fz[i]);
}
}
```
The fptr has been initialised using *FILE.
In this code Npart is currently only 2 entities (its set to 2 by a #define), but will be a lot bigger once I progress the program. Sadly when running this code it seems to work for low numbers of outputs, until 464 per file to be exact.
After that I get the following error message:
```
timestep made, time is 463
Segmentation fault (core dumped)

<p>Scenario 3 - We have <code>viewModelScope</code> in the new version of arch library to cancel jobs with Fragment/Activity lifecycles, but if <code>ViewModel</code> is created with activity reference then it's going to stay there until activity is destroyed. Hence the job can still be executing and fragment is already gone.</p>

57,917,574 | Javascript push() function is not adding objects to an array | <p>I have a for-loop that cycles thru some html elements collected with jquery selectors and extracts some text or values from them. Each loop creates a new object. The object is simple, it is just text and a value. Console.log confirms that the object is created successfully each loop.</p>
<p>Outside the for-loop, I have a variable (kvObjs) that is initialized as an array. At the end of the for-loop, I push the new object into the array. But console.log confirms that the array stays empty.</p>
<p>This is part of a larger piece of code. This appears to be the part that isn't working. The specific function that isn't working is getKVs(), well, it works except for the part that tries to push the object on the array.</p>
<p>I promise you I looked thru all or almost all the "similar questions" and nothing clicked with me. I might have missed something in them, though. I feel like I'm overlooking something obvious.</p>
<p>I have tried to creating an array manually (var x = ["bob", "steve", "frank"]) and then setting another variable equal to that (var y = x) and that seems to work. I even created an array of objects, as in var x = [{"Key":"Bob","Value":10}, {"Key":"Steve","Value":5}], and I think that worked to. But my for-loop doesn't.</p>

<p>This progress remains like forever. It used to be that if I disconnect my device and connect again the next attempt will succeed. Now it is often the case that I need multiple re-connects until I am able to run.</p>
<p>The speculation is the problem is due to ADB hanging and loosing connection somehow, but I do not know how to overcome that.</p>

- device is Nexus 5X, but the same happens on many other devices </p>

57,921,661 | Finding sorted array index of closest int value | <p>I want to use a Lookup-table that contains 205887 positive int values. They are sorted from highest to lowest value.
I have a positive int value (int a). If I have that value inside the table, I want to receive the index (int b) of the value.
If that value does not exist inside the table, I want the index of the nearest-lower value.</p>
<p>This process is performance critical so I want it to be as fast as possible.</p>
<p>Is it possible to create an array with 2^31 values but only 205887 being initialized?
If yes, would that result in the table being roughly the same size of the one I described above?
If yes, could I find b by checking the index of this array with value a and add one to it until I find an initialized entry which contains my value b?</p>

57,935,576 | Is it normal that transfer learning (VGG16) performs worse on CIFAR-10? | <p><strong>Note:</strong> I am not sure this is the right website to ask these kind of questions. Please tell me where I should ask them before downvoting this "because this isn't the right place to ask". Thanks!</p>
<p>I am currently experimenting with deep learning using <a href="https://keras.io" rel="nofollow noreferrer">Keras</a>. I tried already a model similar to the one to be found on <a href="https://keras.io/examples/cifar10_cnn/" rel="nofollow noreferrer">the Keras example</a>. This yields expecting results:</p>
<ul>
<li>80% after 10-15 epochs without data augmentation before overfitting around the 15th epoch and</li>
<li>80% after 50 epochs with data augmentation without any signs of overfitting.</li>
</ul>
<p>After this I wanted to try transfer learning. I did this by using the <a href="https://keras.io/applications/#vgg16" rel="nofollow noreferrer">VGG16</a> network without retraining its weights (see code below). This gave very poor results: 63% accuracy after 10 epochs with a very shallow curve (see picture below) which seems to be indicating that it will achieve acceptable results only (if ever) after a very long training time (I would expect 200-300 epochs before it reaches 80%).</p>
<p><a href="https://i.stack.imgur.com/MWmsT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/MWmsT.png" alt="Transfer learning results"></a></p>
<p>Is this normal behavior for this kind of application? Here are a few things I could imagine to be the cause of these bad results:</p>
<ul>
<li>the CIFAR-10 dataset has images of <code>32x32</code> pixels, which might be too few for the VGG16 net</li>
<li>The filters of VGG16 are not good for CIFAR-10, which would be solved by setting the weights to <code>trainable</code> or by starting with random weights (only copying the model and not the weights)</li>
</ul>
<p>Thanks in advance!</p>

<p><strong>My code:</strong></p>
<p><em>Note that the inputs are 2 datasets (50000 training images and 10000 testing images) which are labeled images with shape <code>32x32x3</code>. Each pixel value is a float in the range <code>[0.0, 1.0]</code>.</em></p>

57,940,197 | Python: force csv reader to include "\n"'s, instead of creating newline | While working on a Twitter scraping project recently, I noticed that tweets oftentimes have the newline character within them, `\n`, which correspond to linebreaks in the tweets.
In the `.csv` files I am creating, instead of deleting them, I would like to keep said `\n` characters, but `csv.writer` keeps interpreting them as new lines, and my `.csv`'s thus become littered with line-breaks everywhere.
I don't want to simply do `string.replace("\n", " ")` each time, as that is not efficient, and I have tried opening the csv with the following,
`with open(file_name, 'a', newline='\n') as f:`, but that does not seem to do the trick.
How could I tell the `csv.writer` to interpret as `\n`'s as literal strings, and keep them?

57,942,250 | What does the %# flag in a printf statement in C? | <p>I am doing the chapter 3 of the book learning C the hard way by Zed Shaw. I am exploring the different string formatting options for printf. I encountered the following flag to put after the '%#' symbol:</p>
<p>The value should be converted to an "alternate form". For o conversions, the first character of the output string is made zero (by prefixing a 0 if it was not zero already). For x and X conversions, a nonzero result has the string "0x" (or "0X" for X conversions) prepended to it. For a, A, e, E, f, F, g, and G conversions, the result will always contain a decimal point, even if no digits follow it (normally, a decimal point appears in the results of those conversions only if a digit follows). For g and G conversions, trailing zeros are not removed from the result as they would otherwise be. For other conversions, the result is undefined. </p>
<p>It seems that '%#' flag is for a kind of type conversion for the printf statement. But I am not sure. Does anyone knows what kind of conversion of actual usage this %# flag has in the printf function in C? I can see any change or conversion for the character "A", which is the one I am using for the flag %# in the last print statement.</p>
<p>This is my code: </p>
<pre><code>#include <math.h>
int main(int argc, char *argv[])
{
int age = 32; // age and height not initialized
int height = 182;
printf("I am %d cm tall.\n", age);
printf("I am %d years old.\n", height);
printf("I wanna go to \"Panama\"\n"); // scaping double quotes

57,945,998 | hopefully a simple Mysql/php query | I'm working with a mysql date column called 'class_of' that has dates ranging from 2014-08-01 to 2019-08-01, all formatted as a date. These dates coincide to what year an article was written.
I have set up my php execution page to grab the year through a url action.
for example - www.mywebsite.com/mypage.php?action=2016
\\\\
$classOf = ($_GET["action"]);
\\\\
I now need to somehow use said variable within a mysql query so my php while loop will only echo dates that have for example 2016 within the date.
This is what I have tried
This works, but I need the year to be a variable
\\\
$query = 'SELECT * FROM news_content WHERE hot = "false" AND trash="false" AND class_of = DATE("2020-08-01") ORDER BY article_id DESC';
\\\
I have tried the below, but with no success
\\\
$query = 'SELECT * FROM news_content WHERE hot = "false" AND trash="false" AND class_of = DATE("<?php echo $classOf ?>-08-01") ORDER BY article_id DESC';
\\\
And
\\\
$query = 'SELECT * FROM news_content WHERE hot = "false" AND trash="false" AND class_of = "<?php echo $classOf ?>" ORDER BY article_id DESC';
\\\
And
\\\
$query = 'SELECT * FROM news_content WHERE hot = "false" AND trash="false" AND class_of LIKE "%<?php echo $classOf ?>%" ORDER BY article_id DESC';
\\\
And
\\\
$query = 'SELECT * FROM news_content WHERE hot = "false" AND trash="false" AND class_of = "<?php date("echo $classOf-08-01")?>" ORDER BY article_id DESC';
\\\
All of the above no success.
Hopefully some has a few ideas or a work around so my while loop only picks up the dates in my variable.

57,946,272 | Cannot insert or update a datetime column with 'yyyy-MM-dd hh:mm:ss' format | <p>I've been trying to wrap my head around what the actual problem is.
I'm thinking it might be collation, When I did </p>
<pre><code>SELECT @@character_set_database, @@collation_database;
</code></pre>
<p>I got this</p>
<pre><code>+--------------------------+----------------------+
| @@character_set_database | @@collation_database |
+--------------------------+----------------------+
| latin1 | latin1_swedish_ci |
+--------------------------+----------------------+
</code></pre>
<p>the mysql workbench has utf8 - default collation as standard. </p>
<p>this is the table I want to update/insert into.</p>
<pre><code>+------------+----------+------+-----+-------------------+----------------+
| Field | Type | Null | Key | Default | Extra |
+------------+----------+------+-----+-------------------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| from | datetime | YES | | NULL | |
| to | datetime | YES | | NULL | |
| breakhours | float | NO | | 0.5 | |
| created | datetime | NO | | CURRENT_TIMESTAMP | |
| assignment | int(11) | NO | MUL | NULL | |
+------------+----------+------+-----+-------------------+----------------+
</code></pre>
<p>this is what happens when I try to insert an entry manually with the mysql console, doesn't work with mysql workbench either.</p>
<pre><code>mysql> insert into TimeEntry(from, to, breakhours, assignment) values('2019-09-14 07:45', '2019-09-14 16:45', 0.5, 1);

</code></pre>
<p>So I put an empty entry into the table</p>
<pre><code>+----+------+------+------------+---------------------+------------+
| id | from | to | breakhours | created | assignment |
+----+------+------+------------+---------------------+------------+
| 2 | NULL | NULL | 0.5 | 2019-09-15 18:51:24 | 1 |
+----+------+------+------------+---------------------+------------+
</code></pre>
<p>but I can't even update from or to here.</p>
<pre><code>mysql> update TimeEntry set from = '2019-09-14 07:45:00' where id = 2;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'from = '2019-09-14 07:45:00' where id = 2' at line 1
</code></pre>
<p>I've been using MySql for years, I've never encountered this problem before, what am I doing wrong?</p>
