I really appreciate any help.

If it is i would appriciate some guidance, if it's not possible is there any other solution for my problem? Thank you!</p>

<p>I didn't specify the type of the weight explicitly(i.e. I did not init my weight by myself. The weight is created by pytorch). What will influence the type of weight in the forward process?</p>

How to do a javascript array sort based on the count of a character in a string? : I have a couple of strings in an array
for example:
String 1: "path/to/file"
String 2: "path"
String 3: "path/to/"
String 4: "path2/to/file"
String 5: "path2/to/file"
String 5: "path2/to"
etc...
The thing that i would like to achieve is to sort the array based on the the count of the slash. So the less count slashes on top.
So it would be like:
String 1: "path"
String 2: "path/to/"
String 3: "path2/to"
String 4: "path/to/file"
String 5: "path2/to/file"
String 6: "path2/to/file"
Thank you for the sollution

Spark Data Frame Random Splitting : <p>I have a spark data frame which I want to divide into train, validation and test in the ratio 0.60, 0.20,0.20. </p>
<p>I used the following code for the same: </p>
<pre><code>def data_split(x):
global data_map_var
d_map = data_map_var.value
data_row = x.asDict()
import random
rand = random.uniform(0.0,1.0)
ret_list = ()
if rand <= 0.6:
ret_list = (data_row['TRANS'] , d_map[data_row['ITEM']] , data_row['Ratings'] , 'train')
elif rand <=0.8:
ret_list = (data_row['TRANS'] , d_map[data_row['ITEM']] , data_row['Ratings'] , 'test')
else:
ret_list = (data_row['TRANS'] , d_map[data_row['ITEM']] , data_row['Ratings'] , 'validation')
return ret_list
split_sdf = ratings_sdf.map(data_split)
train_sdf = split_sdf.filter(lambda x : x[-1] == 'train').map(lambda x :(x[0],x[1],x[2]))
test_sdf = split_sdf.filter(lambda x : x[-1] == 'test').map(lambda x :(x[0],x[1],x[2]))
validation_sdf = split_sdf.filter(lambda x : x[-1] == 'validation').map(lambda x :(x[0],x[1],x[2]))
print "Total Records in Original Ratings RDD is {}".format(split_sdf.count())
print "Total Records in training data RDD is {}".format(train_sdf.count())
print "Total Records in validation data RDD is {}".format(validation_sdf.count())
print "Total Records in test data RDD is {}".format(test_sdf.count())
#help(ratings_sdf)
Total Records in Original Ratings RDD is 300001
Total Records in training data RDD is 180321
Total Records in validation data RDD is 59763
Total Records in test data RDD is 59837
</code></pre>
<p>My original data frame is ratings_sdf which I use to pass a mapper function which does the splitting. </p>
<p>If you check the total sum of train, validation and test does not sum to split (original ratings) count. And these numbers change at every run of the code. </p>
<p>Where is the remaining records going and why the sum is not equal?</p>

How to send hidden info to database : <p>so I have a Dropbox and I have 3 selections. </p>
<pre><code>car
boat
plane
</code></pre>
<p>The value of each one is an image which sends to the database, and reads correctly, by displaying the image of their choice on my page. However, I would like to insert into the database the name of each one too, this will also display under the image. I have a separate column on the table for the hidden info to be input, but am unsure of how to do this that will correspond with the choice they made. Is it possible to do such a thing?</p>

I don't know how to fix the error right after the prompt asking the user to enter another student's name. Like the code compiles and prompts another student's name but the grades when they are displayed they appear as a cumulative grade from the previous student's grades as the new student's grade. It's part of homework, and I only have a few hours left to submit it. I need help as soon as possible please!

why the "?>" tag won't close the php part? : <p>So I was writing some PHP scripts and also some HTML codes but this was what happened:</p>

$q = "SELECT * FROM users WHERE id='1' AND username='test' AND pass='123'; /* the last line of php */
?>
</code></pre>
<p>this was the last code that I used and after that I closed the php and started the html part:</p>
<pre><code><!doctype html>
<html>
<head>
<meta charset="utf-8">
</code></pre>
<p>so at this point when I check localhost and my database I get an error:</p>
<blockquote>
<p>Parse error: syntax error, unexpected 'utf' (T_STRING) in F:\wamp64\www\Login2.php on line 47</p>
</blockquote>
<p>and it's because of the HTML code I used. although I closed the PHP with ?> it's still counting HTML codes as PHP!</p>

What is the simplest way to make a button press to start a method repeatedly (infinite time) in JavaFX? : <p>It would be nice, if I could use a simple timer (seconds or milliseconds) for the repeated method invocation. </p>
<p>If it is possible, I would use another button to stop this method if necessary.</p>
<pre><code>@FXML
private void handleinfiniteActionButton(ActionEvent event) {
methodToRunInfiniteTime();
}
</code></pre>

Divide by zero and no error? : <p>Just threw together a simple test, not for any particular reason other than I like to try to have tests for all my methods even though this one is quite straightforward, or so I thought.</p>
<pre><code> [TestMethod]
public void Test_GetToolRating()
{
var rating = GetToolRating(45.5, 0);
Assert.IsNotNull(rating);
}
private static ToolRating GetToolRating(double total, int numberOf)
{
var ratingNumber = 0.0;
try
{
var tot = total / numberOf;
ratingNumber = Math.Round(tot, 2);
}
catch (Exception ex)
{
var errorMessage = ex.Message;
//log error here
//var logger = new Logger();
//logger.Log(errorMessage);
}
return GetToolRatingLevel(ratingNumber);
}
</code></pre>
<p>As you can see in the test method, I AM dividing by zero. The problem is, it doesn't generate an error. See the error window display below.</p>
<p><a href="https://i.stack.imgur.com/Fjx6O.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Fjx6O.png" alt="Error List View from VS2017"></a></p>
<p>Instead of an error it is giving a value of infinity? What am I missing?So I googled and found that doubles divided by zero DON'T generate an error they either give null or infinity. The question becomes then, how does one test for an Infinity return value?</p>

How to increase icon size in android bottom navigation layout? : <p>I am using the bottom layout navigation style in android that was recently introduced by google in design library 25. In all the tutorials and questions i see, the images in their icons are a normal size, but mine are extra small, despite the fact that the image I'm saving to drawable folder is 72x72. Here is a screenshot:</p>
<p><a href="https://i.stack.imgur.com/6HgS5.png" rel="noreferrer"><img src="https://i.stack.imgur.com/6HgS5.png" alt="enter image description here"></a></p>
<p>The icons should be at least 2, maybe even 3 times that size. How can I do it? Here is my code in my bottom_layout.xml:</p>
<pre><code> <?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/menu_home"
android:title="test"
android:icon="@drawable/tabbarglossary"
app:showAsAction="always|withText"

<item
android:id="@+id/menu_search"
android:title="test2"
android:icon="@drawable/mediationtabbar"

<item
android:id="@+id/menu_notifications"
android:title="test3"
android:icon="@drawable/ic_action_name"
app:showAsAction="always|withText"
/>
</menu>
</code></pre>
<p>and in my activity_main.xml:</p>
<pre><code> <android.support.design.widget.BottomNavigationView
android:id="@+id/navigation"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_alignParentBottom="true"

Object has no attribute '.__dict__' in python3 : <p>I have a test that passes in Python2 and fails in Python3, I'm trying to find out why. The test fails at the following line:</p>
<pre><code>self._timeseries[0].resource.__dict__
</code></pre>
<p>With the error:</p>
<pre><code>AttributeError: 'Resource' object has no attribute '__dict__'
</code></pre>
<p>If I debug the test, and print the object in the debugger, I can see the following:</p>
<pre><code>(Pdb) p self._timeseries[0].resource.__dict__
OrderedDict([('type', 'type_value'), ('labels', {'label1': 'value1', 'label2': 'value2', 'label3': 'value3'})])
</code></pre>
<p>If I do the same in Python3 debugger, I get this:</p>
<pre><code>(Pdb) p self._timeseries[0].resource.__dict__
*** AttributeError: 'Resource' object has no attribute '__dict__'
</code></pre>
<p>Any ideas why this might be happening? The object looks exactly the same if I print it in the debugger without the <code>.__dict__</code>, why is this failing for Python3?</p>

OpenGL shader error with wxwidgets : I'm writing an openGL program using the wxWidgets library, I have it mostly working, but I am getting shader compilation errors due to bad characters being inserted (I think), only I can't find where the characters are or what is causing them. The error is :

I think the wxWidgets related code I have is okay, the window interface loads with a blank white screen, presumably caused by the shader errors. I can post more if needed, thanks.

Reverse iterator returns garbage when optimized : <p>I have a <code>AsIterator</code> template class which takes a numeric-like type, in this example just an <code>int</code>, and converts it into an iterator (<code>++</code> and <code>--</code> increment and decrement the number, and <code>operator*</code> just returns a reference to it).</p>
<p>This works fine <strong>unless it's wrapped into a <code>std::reverse_iterator</code> and compiled with any optimization</strong> (<code>-O</code> is enough). When I optimize the binary, the compiler strips out the dereference call to the <code>reverse_iterator</code> and replaces it with some weird value. It must be noted that it still <strong>makes the correct number of iterations</strong>. It's just the value obtained by reverse iterator that is garbage.</p>
<p>Consider the following code:</p>
<pre class="lang-cpp prettyprint-override"><code>#include <iterator>
#include <cstdio>
template<typename T>
class AsIterator : public std::iterator<std::bidirectional_iterator_tag, T> {
T v;
public:
AsIterator(const T & init) : v(init) {}
T &operator*() { return v; }
AsIterator &operator++() { ++v; return *this; }
AsIterator operator++(int) { AsIterator copy(*this); ++(*this); return copy; }
AsIterator &operator--() { --v; return *this; }
AsIterator operator--(int) { AsIterator copy(*this); --(*this); return copy; }
bool operator!=(const AsIterator &other) const {return v != other.v;}
bool operator==(const AsIterator &other) const {return v == other.v;}
};
typedef std::reverse_iterator<AsIterator<int>> ReverseIt;
int main() {
int a = 0, b = 0;
printf("Insert two integers: ");
scanf("%d %d", &a, &b);
if (b < a) std::swap(a, b);
AsIterator<int> real_begin(a);
AsIterator<int> real_end(b);
for (ReverseIt rev_it(real_end); rev_it != ReverseIt(real_begin); ++rev_it) {
printf("%d\n", *rev_it);
}
return 0;
}
</code></pre>
<p>This should supposingly loop down from the highest inserted number to the lowest and print them, such as in this run (compiled with <code>-O0</code>):</p>
<pre><code>Insert two integers: 1 4
3
2
1
</code></pre>
<p>What I get with <code>-O</code> is instead:</p>
<pre><code>Insert two integers: 1 4
1
0
0
</code></pre>
<p>You can <a href="http://cpp.sh/3htz">try it online here</a>; the numbers may vary but they're always "wrong" when optimizing the binary.</p>
<hr>
<p>What I've tried:</p>
<ul>
<li>hardcoding the input integers is enough to produce the same result;</li>
<li>the issue persists with <em>gcc 5.4.0</em> and <em>clang 3.8.0</em>, also when using <em>libc++</em>;</li>
<li>making all the objects <code>const</code> (i.e. returning <code>const int &</code>, and declaring all variables as such) doesn't fix it;</li>
<li>using the <code>reverse_iterator</code> in the same way on for example some <code>std::vector<int></code> works fine;</li>
<li>if I just use <code>AsIterator<int></code> for a normal forward or backward loop it works fine.</li>
<li>in my tests, the constant <code>0</code> that is printed is actually <em>hardcoded</em> by the compiler, the calls to <code>printf</code> all look like this when compiled with <code>-S -O</code>:</li>
</ul>
<pre><code> movl $.L.str.2, %edi # .L.str.2 is "%d\n"
xorl %eax, %eax
callq printf
</code></pre>
<p>Given the consistency of <em>clang</em> and <em>gcc</em>'s behavior here I am pretty sure they're doing it right and I misunderstood, but I really can't see it.</p>

Prevent program from getting terminated after exception handling : <p>Is there anyway to handle the exceptions in Java and prevent the program from getting terminated? For instance when the user enters an invalid number into a calculator, zero in this example for division in the denominator, I don't want the program to get terminated and show the handled exception message. I want the program to continue and ask for another input.<br/>
Could anyone clarify it with a practical example for me?</p>

What is the best approach database structure for teacher, students and address table? : <p>I have the following tables in my database</p>
<ul>
<li>students</li>
<li>teachers </li>
<li>address</li>
</ul>
<p>I Want to store basic information about students and teacher in its own table, but the address and contact information in address table. If I store the <code>student_id</code> or <code>teacher_id</code> in address table, the student might have same <code>id</code> as any teacher. If I try to query any teacher address by <code>teacher_id</code>. It will query the student who has the same <code>id</code> as well. </p>
<p>So what the best way to figure out this problem? should I create any other table as well or .... </p>
<p>Please suggest me an easiest and best approach.</p>

variable in C# SQL Query not working : So I have a loop in which I grab certain ID's to make a call in a database. There are 2 variable within the query. The first one works fine but the second one returns nothing. I have tested it a lot and know that the correct value is coming through to the query. Not sure what I am doing wrong here. I replace the variable with a hard coded value that I know is returning and it works fine. Here is my code:
SqlDataAdapter d8;
d8 = new SqlDataAdapter("select SUM(CAST(AMOUNT AS BIGINT)) AS NEW_AMOUNT

How to pull with rebase by default in IntelliJ Idea? : <p>By company policy, all pulls unless agreed with tech lead must be done with rebase rather than merge.</p>

<p>My deskmate, working on my same project, uses IntelliJ Idea. Guess what? He always forgets to check pull-with-rebase when pulling, ending up in endless merge commits.</p>
<p>I often have to complain with him for violating the rule I took so long to make a standard, then I need to do force pushing to fix the tree from the mess. Only 2 people here use IntelliJ, other use Eclipse and have no problems with Git.</p>
<p>How do I set the default pull mode in IntelliJ Idea?</p>

difference between 'global varName' and 'self.varName' in python : <p>what is the use of writing 'global varName' in the body of constructor ?
I mean we can achive the same goal by writting 'self.varName' ? For Example</p>
<pre><code>class Mine_Global:
def __init__(self):
global varName
varName = 3
self.newInsVar = 7
if __name__ == "__main__":
global varName
obj1 = Mine_Global()
print varName, obj1.newInsVar;
varName = varName + 2
print varName, obj1.newInsVar;
obj2 = Mine_Global()
print varName, obj2.newInsVar

Cordova / Ionic build android Gradle error: Minimum supported Gradle version is 2.14.1. Current version is 2.13 : <p>This is a solution to the above error that I want to document. I found other similar posts, but none described how this error can be associated with Cordova or Ionic.</p>
<p>If you are not careful, there can be a mismatch between the version of Gradle that Android Studio uses and the version of Gradle that Cordova / cordova-android specifies in its auto-generated application code. As you know, running</p>
<pre><code>$ cordova platform add android
</code></pre>
<p>(or <code>$ ionic platform add android</code>, if you are building an Ionic app) creates the native application code at the-project/platforms/android. </p>
<p>Inside that folder, the file: /the-project/platforms/android/cordova/lib/builders/GradleBuilder.js exports a variable as shown below:</p>
<pre><code>var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'http\\://services.gradle.org/distributions/gradle-x.y-all.zip';
</code></pre>
<p>Where x and y depened on which version of Cordova / cordova-android are being used to build the native application code. </p>
<p>When you run</p>
<pre><code>$ cordova build android
</code></pre>
<p>The version of Gradle specified in the <code>distributionUrl</code> var is the version used for the build.</p>
<p>Now here comes the tricky part. When you import the project into Android Studio, you will most likely get a message strongly recommending that you upgrade Gradle to a newer version, as shown below: </p>
<p><a href="https://i.stack.imgur.com/N1ytd.png" rel="noreferrer"><img src="https://i.stack.imgur.com/N1ytd.png" alt="enter image description here"></a>
If you do this, Android Studio will download a new version of Gradle and store it locally and configure the project to use the newly download local Gradle distribution, which is the radio option below the selected “Use default grade wrapper”, which I ended up deselecting because this will cause errors.</p>
<p><a href="https://i.stack.imgur.com/geQN9.png" rel="noreferrer"><img src="https://i.stack.imgur.com/geQN9.png" alt="enter image description here"></a> </p>
<p>This will cause problems because Android Studio and Cordova will now be attempting to build the application with different versions of Gradle and you will get build errors within Android Studio and also with </p>
<pre><code>$ cordova build android
</code></pre>
<p>in the command line. The solution with Cordova apps is to always keep the Android Studio project set to "Use default gradle wrapper" and ignore the tempting messages to upgrade. If you do want to use a newer version of Gradle, you can always change the distributionUrl var in the file mentioned above (however Cordova strongly discourages modifying code within the platforms folder since it is easily overwritten). At the time of writing this, I cannot tell is there is a way to set the Gradle version at the </p>
<pre><code>$ cordova platform add android
</code></pre>
<p>step, which is when you would want to do it so you are never directly modifiying code inside of the-project/platforms</p>

confused with babel preset configs between @babel/env and @babel/preset-env : <p>I try to config a environment to develop javascript with babel and webpack.</p>
<p>But I don't understand babel configuration about <code>presets</code>.</p>
<p>In <a href="https://babeljs.io/docs/en/usage" rel="noreferrer">Usage Guide</a>, we can see that presets with <code>"@babel/env"</code>.</p>
<p>But other places in document, I cannot see such a configuration more, instead of <code>"@babel/preset-env"</code>. for example here <a href="https://babeljs.io/docs/en/babel-preset-env" rel="noreferrer">https://babeljs.io/docs/en/babel-preset-env</a></p>
<p>I can not find out the difference between <code>"@babel/env"</code> and <code>"@babel/preset-env"</code> everywhere with my poor English, I do really read document again and again, without luck.</p>
<p>Maybe they are same?</p>
<p>Btw, targets sets seems not work, remove targets also can run normally in ie9+(or what's it default targets), if I wish my es6 script can be transformed to compatibility ie8, thus it not most important.</p>

How to use new c# 8.0 features in Razor views : <p>I've updated my ASP.NET Mvc 5 web application to use the new c# 8.0 features through Visual Studio 2019 and everything works fine until I try to use these new features inside a Razor view.</p>

var foo = 1;
var bar = foo switch
{
1 => "one",

This is what I've got at the moment.Obviously, this is just a smaller scope workaround and is not efficient enough for a whole management system.

Rendering dynamic HTML dropdown client-side VS server-side? : I always find it difficult to decide if I should render my HTML server-side or client-side.
Let's say I want to render a dynamic HTML dropdown with following requirements:
- Shows records from a database table at page load
- Must stay up-to-date (users can add/remove records from the database table using the website)
I can't decide between
1.1 Render template with empty drop down server-side
1.2 Populate dropdown client-side using ajax requests (JSON)
1.3 Update dropdown client-side using ajax requests (JSON)
Concern:
Rendering empty elements before populating feels ugly to me
AND
2.1 Render populated dropdown server-side
2.2 Update dropdown client-side using ajax requests (JSON)
Concern:
Why would you render server-side if you are still updating it client-side?
What solution is more commonly used in web development? Feel free to share different approaches...

Building one web project breaks the compiled version of the second in solution : <p>I have a big solution with 30 projects of which 2 are web projects (MVC and WebAPI) with a bunch of background class library projects.</p>
<p>I have visual studio set up to host the web projects in IIS.</p>
<p>If I do a clean build, followed by a full build of the entire solution, then accessing both projects via a browser works fine. (they are in diff folders and hosted on diff 'domains' in iis) </p>
<p>If I make NO code changes, simply rebuild one of the 2 web projects, the OTHER one stops working. </p>
<p>To be clear, rebuilding the WebAPI project causes the MVC project to have errors. And vice versa.</p>
<p>The error I get is saying that System.Web.Http.Formatter is not found. The detail says that the located assembly version is different from the reference version. Checking the bin folder shows that that is not the case. </p>

React-Native cannot write first letter with noncapital : <p>I have some trouble with react-native. I have an Input component(like textfield) for user to enter his email address, but the thing is that, first letter always comes as capital letter default and it is impossible to make it non-capital. How can I change it like first letter can be small, as well? <a href="https://i.stack.imgur.com/ja4B7.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ja4B7.png" alt="enter image description here"></a></p>

type parameter `U` of call of method `then`. Missing annotation : <p>I have an object which might contain a promise property declared thus:</p>
<pre><code>type PromiseAction = {
+type: string,
promise: ?Promise<any>,
};
</code></pre>
<p>The <code>action</code> argument to a function is declared to be of type PromiseAction:</p>
<pre><code>(action: PromiseAction) =>
</code></pre>
<p>Later on I check whether the received <code>action</code> object does have a <code>promise</code> property and if <code>action.promise</code> has a <code>then</code>:</p>
<pre><code>if (action.promise && typeof action.promise.then === 'function') {
</code></pre>
<p>If it does then I hook onto the promise chain:</p>
<pre><code>return promise.then(
</code></pre>
<p>At which point I get the error: "type parameter <code>U</code> of call of method <code>then</code>. Missing annotation"</p>
<p>I can see in the <a href="https://github.com/facebook/flow/blob/v0.56.0/lib/core.js#L600" rel="noreferrer">source for flow</a> that the <code>then</code> property of a <code>Promise</code> has a <code>U</code> parameter which, I assume, is the one being asked for.</p>
<p>How can an provide that <code>U</code> annotation if I only have only one parameter <code>Promise<+R></code> in the type declaration?</p>

RxJS observable which emits both previous and current value starting from first emission : <p>I have a <a href="http://reactivex.io/rxjs/manual/overview.html#behaviorsubject" rel="noreferrer">BehaviorSubject</a> which emits JavaScript objects periodically. I want to construct another observable which will emit both previous and current values of the underlying observable in order to compare two objects and determine the delta.</p>
<p>The <a href="http://reactivex.io/rxjs/class/es6/Observable.js~Observable.html#instance-method-pairwise" rel="noreferrer"><code>pairwise()</code></a> or <a href="http://reactivex.io/rxjs/class/es6/Observable.js~Observable.html#instance-method-bufferCount" rel="noreferrer"><code>bufferCount(2, 1)</code></a> operators are looking like a good fit, but they start emitting only after buffer is filled, but I require this observable to start emitting from the first event of the underlying observable.</p>
<pre><code>subject.someBufferingOperator()
.subscribe([previousValue, currentValue] => {
/** Do something */
})
;
</code></pre>
<blockquote>
<p>On first emission the <code>previousValue</code> could be just <code>null</code>.</p>
</blockquote>
<p>Is there some built-in operators that I can use to achieve the desired result?</p>

CSS center div with <p> to parent div, vertically and horizontally : <p>I have the following HTML/CSS where I try to center a <code>div</code> with some <code><p></code> to their parent <code>div</code> wrapper.

I think I am missing a point, but I dont get it. Could someone tell me?</p>

Why is only one table row updated?

}
if(isset($_POST['update'])){
$UpdateQuery = "UPDATE users SET rank='$_POST[rank]' WHERE user_id='$_POST[hidden]'";
$con->query($UpdateQuery);
}
//$sql = "SELECT * from users";
//$myData = mysql_query($sql, $con);
$result = $MySQLi_CON->query("SELECT * FROM users")
or die(mysql_error());

React Navigation - navigating to another tab and reset stack : <p>I'm trying to route from one StackNavigator to another, both of which are inside a TabNavigator. I'm currently able to get there by simply doing:</p>
<pre><code>this.props.navigation.navigate('Screen3')
</code></pre>
<p>But I also want to reset that tab when I go to it. Here is how my app navigators are generally set up:</p>
<pre><code>- Main (StackNavigator)
- LoginScreen
- MainTabs (TabNavigator)
- Tab1 (StackNavigator)
- Screen1
- Screen2
- Tab2 (StackNavigator)
- Screen3
- Screen4
</code></pre>
<p>How could I navigate to <code>Screen3</code> but also reset the StackNavigator <code>Tab2</code>?</p>
<p>I've also tried doing this, to no avail:</p>
<pre><code>let resetAction = NavigationActions.reset({
index: 0,
key: 'Tab2',
actions: [
NavigationActions.navigate({ routeName: 'Screen3' })
],
});
this.props.navigation.dispatch(resetAction);
