Having read some of the answers, they identify correctly that align-content takes no affect if the flex content is not wrapped. However what they don't understand is align-items still plays an important role when there is wrapped content:

In the following two examples, align-items is used to center the items within each row, then we change align-content to see it's effect.

Example 1:

align-content: flex-start;

Example 2:

    align-content: flex-end;

Here's the code:

<div class="container">
    <div class="child" style="height: 30px;">1</div>
    <div class="child" style="height: 50px;">2</div>
    <div class="child" style="height: 60px;">3</div>
    <div class="child" style="height: 40px;">4</div>
    <div class="child" style="height: 50px;">5</div>
    <div class="child" style="height: 20px;">6</div>
    <div class="child" style="height: 90px;">7</div>
    <div class="child" style="height: 50px;">8</div>
    <div class="child" style="height: 30px;">9</div>
    <div class="child" style="height: 40px;">10</div>
    <div class="child" style="height: 30px;">11</div>
    <div class="child" style="height: 60px;">12</div>
</div>

<style>
.container {
    display: flex;
    width: 300px;
    flex-flow: row wrap;
    justify-content: space-between;
    align-items: center;
    align-content: flex-end;
    background: lightgray;
    height: 400px;
}
.child {
    padding: 12px;
    background: red;
    border: solid 1px black;
}
</style>

As others said, there is no such thing in C++. Having said that, I tend to use the style in which the standard library is written - K & R.

Also, see the FAQ entry by Bjarne Stroustrup.

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

AppDomain.UnhandledException Event

This event provides notification of uncaught exceptions. It allows the application to log information about the exception before the system default handler reports the exception to the user and terminates the application.

   public App()
   {
      AppDomain currentDomain = AppDomain.CurrentDomain;
      currentDomain.UnhandledException += new UnhandledExceptionEventHandler(MyHandler);    
   }

   static void MyHandler(object sender, UnhandledExceptionEventArgs args) 
   {
      Exception e = (Exception) args.ExceptionObject;
      Console.WriteLine("MyHandler caught : " + e.Message);
      Console.WriteLine("Runtime terminating: {0}", args.IsTerminating);
   }

If the UnhandledException event is handled in the default application domain, it is raised there for any unhandled exception in any thread, no matter what application domain the thread started in. If the thread started in an application domain that has an event handler for UnhandledException, the event is raised in that application domain. If that application domain is not the default application domain, and there is also an event handler in the default application domain, the event is raised in both application domains.

For example, suppose a thread starts in application domain "AD1", calls a method in application domain "AD2", and from there calls a method in application domain "AD3", where it throws an exception. The first application domain in which the UnhandledException event can be raised is "AD1". If that application domain is not the default application domain, the event can also be raised in the default application domain.

In Notepad++ on the Language menu you will find the menu item - 'J' and under this menu item chose the language - JSON.

Once you select the JSON language then you won't have to worry about how to save it. When you save it it will by default save it as .JSON file, you have to just select the location of the file.

Setting the timeout in the web.xml is the correct way to set the timeout.

Use the Immediate Window to Execute Commands

The Immediate Window can also be used to execute commands. Just type a > followed by the command.

For example >shell cmd will start a command shell (this can be useful to check what environment variables were passed to Visual Studio, for example). >cls will clear the screen.

Here is a list of commands that are so commonly used that they have their own aliases: https://msdn.microsoft.com/en-us/library/c3a0kd3x.aspx

Android IntentService vs Service

1.Service

• A Service is invoked using startService().
• A Service can be invoked from any thread.
• A Service runs background operations on the Main Thread of the Application by default. Hence it can block your Application’s UI.
• A Service invoked multiple times would create multiple instances.
• A service needs to be stopped using stopSelf() or stopService().
• Android service can run parallel operations.

2. IntentService

• An IntentService is invoked using Intent.
• An IntentService can in invoked from the Main thread only.
• An IntentService creates a separate worker thread to run background operations.
• An IntentService invoked multiple times won’t create multiple instances.
• An IntentService automatically stops after the queue is completed. No need to trigger stopService() or stopSelf().
• In an IntentService, multiple intent calls are automatically Queued and they would be executed sequentially.
• An IntentService cannot run parallel operation like a Service.

In General...

The method exposed by sykora is the best option in this case. But sometimes is not the easiest and it's not a general method. For a general method use git cherry-pick:

To achieve what OP wants, its a 2-step process:

Step 1 - Note which commits from master you want on a newbranch

Execute

git checkout master
git log

Note the hashes of (say 3) commits you want on newbranch. Here I shall use:
C commit: 9aa1233
D commit: 453ac3d
E commit: 612ecb3

Note: You can use the first seven characters or the whole commit hash

Step 2 - Put them on the newbranch

git checkout newbranch
git cherry-pick 612ecb3
git cherry-pick 453ac3d
git cherry-pick 9aa1233

OR (on Git 1.7.2+, use ranges)

git checkout newbranch
git cherry-pick 612ecb3~1..9aa1233

git cherry-pick applies those three commits to newbranch.

Try putting the driver jar in the server lib folder. ($CATALINA_HOME/lib)

I believe that the connection pool needs to be set up even before the application is instantiated. (At least that's how it works in Jboss)

If you want they to be paragraph, then use it.

<p><label for="id1">label1:</label> <input type="text" id="id1"/></p>
<p><label for="id2">label2:</label> <input type="text" id="id2"/></p>

Both <label> and <input> are paragraph and flow content so you can insert as paragraph elements and as block elements.

It looks like someone might have revoked the permissions on sys.configurations for the public role. Or denied access to this view to this particular user. Or the user has been created after the public role was removed from the sys.configurations tables.

Provide SELECT permission to public user sys.configurations object.

Try using an empty collapse argument within the paste function:

paste(sdata, collapse = '')

I figured it out. json_encode handles objects differently than strings. I cast the object to a string and it works now.

foreach($xml->children() as $state)
{
    $states[]= array('state' => (string)$state->name); 
}       
echo json_encode($states);

The safest way is to put the files you want kept to yourself outside of the web root directory, like Damien suggested. This works because the web server follows local file system privileges, not its own privileges.

However, there are a lot of hosting companies that only give you access to the web root. To still prevent HTTP requests to the files, put them into a directory by themselves with a .htaccess file that blocks all communication. For example,

Order deny,allow
Deny from all

Your web server, and therefore your server side language, will still be able to read them because the directory's local permissions allow the web server to read and execute the files.

After implementing different versions of solution, I finally made a trade-off to achieve these goals based on CLRS version.

Goal

• not using list.pop() to iterate values
• not creating a new list for saving result, modifying the original one instead
• not using float('inf') as sentinel values

def mergesort(A, p, r):
    if(p < r):
        q = (p+r)//2
        mergesort(A, p, q)
        mergesort(A, q+1, r)
        merge(A, p, q, r)

def merge(A, p, q, r):
    L = A[p:q+1]
    R = A[q+1:r+1]
    i = 0
    j = 0
    k = p
    while i < len(L) and j < len(R):
        if(L[i] < R[j]):
            A[k] = L[i]
            i += 1
        else:
            A[k] = R[j]
            j += 1
        k += 1
    if i < len(L):
        A[k:r+1] = L[i:]

if __name__ == "__main__":
    items = [6, 2, 9, 1, 7, 3, 4, 5, 8]
    mergesort(items, 0, len(items)-1)
    print items
    assert items == [1, 2, 3, 4, 5, 6, 7, 8, 9]

You need to use the ajax-cross-origin plugin: http://www.ajax-cross-origin.com/

Just add the option crossOrigin: true

$.ajax({
    crossOrigin: true,
    url: url,
    success: function(data) {
        console.log(data);
    }
});

For a quick solution, I usually do like this.

This approach will allow the user to enter date in any format they like in the textbox, and finally format in mm/dd/yyyy format when he is done editing. So it is quite flexible:

Private Sub TextBox1_Exit(ByVal Cancel As MSForms.ReturnBoolean)
    If TextBox1.Text <> "" Then
        If IsDate(TextBox1.Text) Then
            TextBox1.Text = Format(TextBox1.Text, "mm/dd/yyyy")
        Else
            MsgBox "Please enter a valid date!"
            Cancel = True
        End If
    End If
End Sub

However, I think what Sid developed is a much better approach - a full fledged date picker control.

I just wanna add this, when you access the position of the array like

arg[n]

is the same as

*(arg + n) than means an offset of n starting from de arg address.

so arg[0] will be *arg

Passwords in the database should be stored encrypted. One way encryption (hashing) is recommended, such as SHA2, SHA2, WHIRLPOOL, bcrypt DELETED: MD5 or SHA1. (those are older, vulnerable

In addition to that you can use additional per-user generated random string - 'salt':

$salt = MD5($this->createSalt());

$Password = SHA2($postData['Password'] . $salt);

createSalt() in this case is a function that generates a string from random characters.

EDIT: or if you want more security, you can even add 2 salts: $salt1 . $pass . $salt2

Another security measure you can take is user inactivation: after 5 (or any other number) incorrect login attempts user is blocked for x minutes (15 mins lets say). It should minimize success of brute force attacks.

If you want to pass the result as a rendered template you have to load and render a template, pass the result of rendering it to the json.This could look like that:

from django.template import loader, RequestContext

#render the template
t=loader.get_template('sample/sample.html')
context=RequestContext()
html=t.render(context)

#create the json
result={'html_result':html)
json = simplejson.dumps(result)

return HttpResponse(json)

That way you can pass a rendered template as json to your client. This can be useful if you want to completely replace ie. a containing lots of different elements.

With little modification to @Hephaeastus 's code in one of the above comments, wrote the below method to list down folders and objects (files) in a given path. Works similar to s3 ls command.

from boto3 import session

def s3_ls(profile=None, bucket_name=None, folder_path=None):
    folders=[]
    files=[]
    result=dict()
    bucket_name = bucket_name
    prefix= folder_path
    session = boto3.Session(profile_name=profile)
    s3_conn   = session.client('s3')
    s3_result =  s3_conn.list_objects_v2(Bucket=bucket_name, Delimiter = "/", Prefix=prefix)
    if 'Contents' not in s3_result and 'CommonPrefixes' not in s3_result:
        return []

    if s3_result.get('CommonPrefixes'):
        for folder in s3_result['CommonPrefixes']:
            folders.append(folder.get('Prefix'))

    if s3_result.get('Contents'):
        for key in s3_result['Contents']:
            files.append(key['Key'])

    while s3_result['IsTruncated']:
        continuation_key = s3_result['NextContinuationToken']
        s3_result = s3_conn.list_objects_v2(Bucket=bucket_name, Delimiter="/", ContinuationToken=continuation_key, Prefix=prefix)
        if s3_result.get('CommonPrefixes'):
            for folder in s3_result['CommonPrefixes']:
                folders.append(folder.get('Prefix'))
        if s3_result.get('Contents'):
            for key in s3_result['Contents']:
                files.append(key['Key'])

    if folders:
        result['folders']=sorted(folders)
    if files:
        result['files']=sorted(files)
    return result

This lists down all objects / folders in a given path. Folder_path can be left as None by default and method will list the immediate contents of the root of the bucket.

For using FusedLocationProviderClient with Google Play Services 11 and higher:

see here: How to get current Location in GoogleMap using FusedLocationProviderClient

For using (now deprecated) FusedLocationProviderApi:

If your project uses Google Play Services 10 or lower, using the FusedLocationProviderApi is the optimal choice.

The FusedLocationProviderApi offers less battery drain than the old open source LocationManager API. Also, if you're already using Google Play Services for Google Maps, there's no reason not to use it.

Here is a full Activity class that places a Marker at the current location, and also moves the camera to the current position.

It also checks for the Location permission at runtime for Android 6 and later (Marshmallow, Nougat, Oreo). In order to properly handle the Location permission runtime check that is necessary on Android M/Android 6 and later, you need to ensure that the user has granted your app the Location permission before calling mGoogleMap.setMyLocationEnabled(true) and also before requesting location updates.

Result:

Show permission explanation if needed using an AlertDialog (this happens if the user denies a permission request, or grants the permission and then later revokes it in the settings):

Prompt the user for Location permission by calling ActivityCompat.requestPermissions():

Move camera to current location and place Marker when the Location permission is granted:

The trick here is to put the library AFTER the module you are compiling. The problem is a reference thing. The linker resolves references in order, so when the library is BEFORE the module being compiled, the linker gets confused and does not think that any of the functions in the library are needed. By putting the library AFTER the module, the references to the library in the module are resolved by the linker.

just call this method simply:

((LinearLayoutManager)recyclerView.getLayoutManager()).scrollToPositionWithOffset(yourItemPosition,0);

instead of:

recyclerView.scrollToPosition(yourItemPosition);

This will print 76.66:

print("Number: ", f"{76.663254: .2f}")

Use this in your RelativeLayout

android:gravity="center_vertical"

With Font Awesome ICONS, I used the following code to produce a round button/image with the color of your choice.

<code>

<span class="fa fa-circle fa-lg" style="color:#ff0000;"></span>

I don't know if you ever found an answer to this but I DIDN'T need MAMP PRO to do this. Simply goto the correct path by following what others have said. It's something like...

MAMP-> bin-> php-> php(your php version)-> conf-> php.ini

The key here is where you're editing the file. I was making the mistake of editing the commented part of the ini file. You actually have to scroll down to LINE #472 where it says "display_errors = Off and change it to On. Hope this helps any

Everything is contained in the .git directory. Just back that up along with your project as you would any file.

I believe it is -- when you are working with JS strings.

If you are generating HTML, though, you will have to use <br /> tags (not \n, as you're not dealing with JS anymore)

For those looking for a way to do this with $object->method:

call_user_func_array(array($object, 'method_name'), $array);

I was successful with this in a construct function that calls a variable method_name with variable parameters.

I had an issue at work. The oracle server was "patched" and one of the databases I use could not be connect via the TNSNames entry but via Basic connection. The Database was up and admin could see it was up and running.

Addionally any application that used TNS for connecting to the database would not work either.

The problem found was that the database name was not correct in the TNS file but for some reason it's been working for years. Correcting the name fixed it for us. I did find that Oracle SQL Developer kept using the old TNS entry even after I updated it and I don't feel like reinstalling it for just one DB Connection. It appears that when the database was created it was given a smaller name then the others and via some cut and paste action within the TNSNames file it got mixed up. No one is sure how its worked as we're investigating it but the oracle patch ensured that the name had to be correct

An example of the name was it was down as "DBName.Part1.Part2" but in fact the DB name was "DBName"

Consider if instead it was:

class RectangularRoom(object):
    def __init__(self, width, height):
        pass

    def cleanTileAtPosition(self, pos):
        pass

    def isTileCleaned(self, m, n):
        pass

and you subclass and forget to tell it how to isTileCleaned() or, perhaps more likely, typo it as isTileCLeaned(). Then in your code, you'll get a None when you call it.

• Will you get the overridden function you wanted? Definitely not.
• Is None valid output? Who knows.
• Is that intended behavior? Almost certainly not.
• Will you get an error? It depends.

raise NotImplmentedError forces you to implement it, as it will throw an exception when you try to run it until you do so. This removes a lot of silent errors. It's similar to why a bare except is almost never a good idea: because people make mistakes and this makes sure they aren't swept under the rug.

Note: Using an abstract base class, as other answers have mentioned, is better still, as then the errors are frontloaded and the program won't run until you implement them (with NotImplementedError, it will only throw an exception if actually called).

On a Mac you can also pinch-zoom, i.e. move your thumb and index finger together or apart.

I created a dialog with the option to choose Image from gallery or camera. with a callback as

• Uri if the image is from the gallery
• String as a file path if the image is captured from the camera.
• Image as File the image chosen from camera needs to be uploaded on the internet as Multipart file data

At first we to define permission in AndroidManifest as we need to write external store while creating a file and reading images from gallery

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Create a file_paths xml in app/src/main/res/xml/file_paths.xml

with path

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

Then we need to define file provier to generate Content uri to access file stored in external storage

<provider
    android:name="androidx.core.content.FileProvider"
    android:authorities="${applicationId}.provider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data

        android:resource="@xml/file_paths" />
</provider>

You're passing the same model to the partial view as is being passed to the main view, and they are different types. The model is a DbSet of Notes, where you need to pass in a single Note.

You can do this by adding a parameter, which I'm guessing as it's the create form would be a new Note

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

This worked for me:

File >> Project Structure >> Modules >> Dependency >> + (on left-side of window)

clicking the "+" sign will let you designate the directory where you have unpacked JavaFX's "lib" folder.

Scope is Compile (which is the default.) You can then edit this to call it JavaFX by double-clicking on the line.

then in:

Run >> Edit Configurations

Add this line to VM Options:

--module-path /path/to/JavaFX/lib --add-modules=javafx.controls

(oh and don't forget to set the SDK)

• You can customize every short cut operation according to your habbit.

Just go to Tools > Options > Environment > Keyboard > Find the action you want to set key board short-cut and change according to keyboard habbit.

Lets take an example where you want to print numbers from 0 to n in the same line. You can do this with the help of following code.

n=int(raw_input())
i=0
while(i<n):
    print i,
    i = i+1

At input, n = 5

Output : 0 1 2 3 4 

You can read more about function types in the language specification in sections 3.5.3.5 and 3.5.5.

The TypeScript compiler will infer types when it can, and this is done you do not need to specify explicit types. so for the greeter example, greet() returns a string literal, which tells the compiler that the type of the function is a string, and no need to specify a type. so for instance in this sample, I have the greeter class with a greet method that returns a string, and a variable that is assigned to number literal. the compiler will infer both types and you will get an error if you try to assign a string to a number.

class Greeter {
    greet() {
        return "Hello, ";  // type infered to be string
    }
} 

var x = 0; // type infered to be number

// now if you try to do this, you will get an error for incompatable types
x = new Greeter().greet(); 

Similarly, this sample will cause an error as the compiler, given the information, has no way to decide the type, and this will be a place where you have to have an explicit return type.

function foo(){
    if (true)
        return "string"; 
    else 
        return 0;
}

This, however, will work:

function foo() : any{
    if (true)
        return "string"; 
    else 
        return 0;
}

Check your project build is in Debug mode not Release, I had some problem for debugging always I forget to change Release mode to Debug (Xamarin Users)

I was working with EasyRepro, and when I debugged my code it was clicking on the element which is visible and enabled, and not navigating as expected. But finally I understood the root cause for the issue.

My Chrome was zoomed out 90%

Once i reset the zoom level, it clicked on the correct element and successfully navigated to next page.

Your code does not work because it is not doing what you are expecting it to do. Switch blocks take in a value, and compare each case to the given value, looking for equality. Your comparison value is an integer, but most of your case expressions resolve to a boolean value.

So, for example, say liCount = 2. Your first case will not match, because 2 != 0. Your second case, (liCount<=5 && liCount>0) evaluates to true, but 2 != true, so this case will not match either.

For this reason, as many others have said, you should use a series of if...then...else if blocks to do this.

You need to define the receiver as a class in the manifest and it will receive the intent:

<application
  ....
  <receiver android:name=".ToastReceiver">
    <intent-filter>
      <action android:name="com.unitedcoders.android.broadcasttest.SHOWTOAST"/>
    </intent-filter>
  </receiver>
</application>

And you don't need to create the class manually inside ToastDisplay.

In the code you provided, you must be inside ToastDisplay activity to actually receive the Intent.

I like ThomasA's answer, but wanted a more realistic context with the wave being used to separate two divs. So I created a more complete demo where the separator SVG gets positioned perfectly between the two divs.

Now I thought it would be cool to take it further. What if we could do this all in CSS without the need for the inline SVG? The point being to avoid extra markup. Here's how I did it:

Two simple <div>:

Demo Wavy divider (with CSS pseudo-elements to avoid extra markup)

It was a bit trickier to position than with an inline SVG but works just as well. (Could use CSS custom properties or pre-processor variables to keep the height and padding easy to read.)

To edit the colors, you need to edit the URL-encoded SVG itself.

Pay attention (like in the first demo) to a change in the viewBox to get rid of unwanted spaces in the SVG. (Another option would be to draw a different SVG.)

Another thing to pay attention to here is the background-size set to 100% 100% to get it to stretch in both directions.

public static void main(String[] args) {
    Scanner input=new Scanner(System.in);
    int[] numbers=new int[5];
    String x=null;
    System.out.print("enter the number 10:"+"/n");
    for(int i=0;i<5;i++){
        numbers[i] = input.nextInt();
    }
    System.out.print("Numbers  :  count"+"\n");
    int count=1;
    Arrays.sort(numbers);
    for(int z=0;z<5;z++){
        for(int j=0;j<z;j++){
            if(numbers[z]==numbers[j] & j!=z){
                count=count+1;
            }
        }
        System.out.print(numbers[z]+" - "+count+"\n");
        count=1;

    }

You can. Transparent canvas can be quickly faded by using destination-out global composite operation. It's not 100% perfect, sometimes it leaves some traces but it could be tweaked, depending what's needed (i.e. use 'source-over' and fill it with white color with alpha at 0.13, then fade to prepare the canvas).

// Fill canvas using 'destination-out' and alpha at 0.05
ctx.globalCompositeOperation = 'destination-out';
ctx.fillStyle = "rgba(255, 255, 255, 0.05)";
ctx.beginPath();
ctx.fillRect(0, 0, width, height);
ctx.fill();
// Set the default mode.
ctx.globalCompositeOperation = 'source-over';

Both JBoss and Tomcat are Java servlet application servers, but JBoss is a whole lot more. The substantial difference between the two is that JBoss provides a full Java Enterprise Edition (Java EE) stack, including Enterprise JavaBeans and many other technologies that are useful for developers working on enterprise Java applications.

Tomcat is much more limited. One way to think of it is that JBoss is a Java EE stack that includes a servlet container and web server, whereas Tomcat, for the most part, is a servlet container and web server.

set.seed is a base function that it is able to generate (every time you want) together other functions (rnorm, runif, sample) the same random value.

Font's don't have a color; only when using the font you can set the color of the component. For example, when using a JTextArea:

JTextArea txt = new JTextArea();
Font font = new Font("Verdana", Font.BOLD, 12);
txt.setFont(font);
txt.setForeground(Color.BLUE);

According to this link, the createFont() method creates a new Font object with a point size of 1 and style PLAIN. So, if you want to increase the size of the Font, you need to do this:

 Font font = Font.createFont(Font.TRUETYPE_FONT, new File("A.ttf"));
 return font.deriveFont(12f);

Another option may be this John Resig remove method. can better fit what you need. if you know the index in the array.

In Python for assertion I use:

assert len(driver.find_elements_by_css_selector("your_css_selector")) == 0

Try this, it worked for me on Google Chrome:

<style media="print" type="text/css">
    .page {
        background-color: white !important;
    }
</style>

Kinda little late but I tried to extend @Tobia's answer to set the layout "horizontal" or "vertical" driven by the command argument e.g.

{"keys": ["f6"], "command": "split_pane", "args": {"split_type": "vertical"} } 

Plugin code:

import sublime_plugin


class SplitPaneCommand(sublime_plugin.WindowCommand):
    def run(self, split_type):
        w = self.window
        if w.num_groups() == 1:
            if (split_type == "horizontal"):
                w.run_command('set_layout', {
                    'cols': [0.0, 1.0],
                    'rows': [0.0, 0.33, 1.0],
                    'cells': [[0, 0, 1, 1], [0, 1, 1, 2]]
                })
            elif (split_type == "vertical"):
                w.run_command('set_layout', {
                    "cols": [0.0, 0.46, 1.0],
                    "rows": [0.0, 1.0],
                    "cells": [[0, 0, 1, 1], [1, 0, 2, 1]]
                })

            w.focus_group(0)
            w.run_command('clone_file')
            w.run_command('move_to_group', {'group': 1})
            w.focus_group(1)
        else:
            w.focus_group(1)
            w.run_command('close')
            w.run_command('set_layout', {
                'cols': [0.0, 1.0],
                'rows': [0.0, 1.0],
                'cells': [[0, 0, 1, 1]]
            })

Spark – Overwrite the output directory:

Spark by default doesn’t overwrite the output directory on S3, HDFS, and any other file systems, when you try to write the DataFrame contents to an existing directory, Spark returns runtime error hence. To overcome this Spark provides an enumeration org.apache.spark.sql.SaveMode.Overwrite to overwrite the existing folder.

We need to use this Overwrite as an argument to mode() function of the DataFrameWrite class, for example.

df. write.mode(SaveMode.Overwrite).csv("/tmp/out/foldername")

or you can use the overwrite string.

df.write.mode("overwrite").csv("/tmp/out/foldername")

Besides Overwrite, SaveMode also offers other modes like SaveMode.Append, SaveMode.ErrorIfExists and SaveMode.Ignore

For older versions of Spark, you can use the following to overwrite the output directory with the RDD contents.

sparkConf.set("spark.hadoop.validateOutputSpecs", "false") val sparkContext = SparkContext(sparkConf)

This will print all the subdirectories of the current directory:

print [name for name in os.listdir(".") if os.path.isdir(name)]

I'm not sure what you're doing with split("-"), but perhaps this code will help you find a solution?

If you want the full pathnames of the directories, use abspath:

print [os.path.abspath(name) for name in os.listdir(".") if os.path.isdir(name)]

Note that these pieces of code will only get the immediate subdirectories. If you want sub-sub-directories and so on, you should use walk as others have suggested.

I've created a simple directive to enable standard input[type="date"] form elements to work correctly with AngularJS ~1.2.16.

Look here: https://github.com/betsol/angular-input-date

And here's the demo: http://jsfiddle.net/F2LcY/1/

man ssh gives me this options would could be useful.

-i identity_file Selects a file from which the identity (private key) for RSA or DSA authentication is read. The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for pro- tocol version 2. Identity files may also be specified on a per- host basis in the configuration file. It is possible to have multiple -i options (and multiple identities specified in config- uration files).

So you could create an alias in your bash config with something like

alias ssh="ssh -i /path/to/private_key"

I haven't looked into a ssh configuration file, but like the -i option this too could be aliased

-F configfile Specifies an alternative per-user configuration file. If a configuration file is given on the command line, the system-wide configuration file (/etc/ssh/ssh_config) will be ignored. The default for the per-user configuration file is ~/.ssh/config.

The traceback module provides methods for formatting and printing exceptions and their tracebacks, e.g. this would print exception like the default handler does:

import traceback

try:
    1/0
except Exception:
    traceback.print_exc()

Output:

Traceback (most recent call last):
  File "C:\scripts\divide_by_zero.py", line 4, in <module>
    1/0
ZeroDivisionError: division by zero

What about:

#region Using Statements
using System;
using System.Xml;
#endregion 

class Program {
    static void Main( string[ ] args ) {
        XmlDocument doc = new XmlDocument( );

        //(1) the xml declaration is recommended, but not mandatory
        XmlDeclaration xmlDeclaration = doc.CreateXmlDeclaration( "1.0", "UTF-8", null );
        XmlElement root = doc.DocumentElement;
        doc.InsertBefore( xmlDeclaration, root );

        //(2) string.Empty makes cleaner code
        XmlElement element1 = doc.CreateElement( string.Empty, "body", string.Empty );
        doc.AppendChild( element1 );

        XmlElement element2 = doc.CreateElement( string.Empty, "level1", string.Empty );
        element1.AppendChild( element2 );

        XmlElement element3 = doc.CreateElement( string.Empty, "level2", string.Empty );
        XmlText text1 = doc.CreateTextNode( "text" );
        element3.AppendChild( text1 );
        element2.AppendChild( element3 );

        XmlElement element4 = doc.CreateElement( string.Empty, "level2", string.Empty );
        XmlText text2 = doc.CreateTextNode( "other text" );
        element4.AppendChild( text2 );
        element2.AppendChild( element4 );

        doc.Save( "D:\\document.xml" );
    }
}

_{(1) Does a valid XML file require an xml declaration?
(2) What is the difference between String.Empty and “” (empty string)?}

The result is:

<?xml version="1.0" encoding="UTF-8"?>
<body>
  <level1>
    <level2>text</level2>
    <level2>other text</level2>
  </level1>
</body>

But I recommend you to use LINQ to XML which is simpler and more readable like here:

#region Using Statements
using System;
using System.Xml.Linq;
#endregion 

class Program {
    static void Main( string[ ] args ) {
        XDocument doc = new XDocument( new XElement( "body", 
                                           new XElement( "level1", 
                                               new XElement( "level2", "text" ), 
                                               new XElement( "level2", "other text" ) ) ) );
        doc.Save( "D:\\document.xml" );
    }
}

Just a different approach:

int runs = 0; 
bool batting = true; 
string scorecard;

while (batting = runs < 400)
    scorecard += "!" + runs++;

return scorecard.Split("!");

Initial array

   int[] array = {5,6,51,4,3,2};

if you want remove 51 that is index 2, use following

 for(int i = 2; i < array.length -1; i++){
    array[i] = array[i + 1];
  }

<script type="text/javascript">

EDIT

A great way of handling this is with regular expressions.

string modifiedString = Regex.Replace(originalString, @"(\r\n)|\n|\r", "<br/>");

This will replace any of the 3 legal types of newline with the html tag.

after you add the user for testing. the user should get an email. open that email by your iOS device, then click "Start testing" it will bring you to testFlight to download the app directly. If you open that email via computer, and then click "Start testing" it will show you another page which have the instruction of how to install the app. and that invitation code is on the last line. those All upper case letters is the code.

If the other class is compiled as a library (i.e. a dll) and this is how you want it, you should add a reference from visual studio, browse and point to to the dll file.

If what you want is to incorporate the OtherClassFile.cs into your project, and the namespace is already identical, you can:

1. Close your solution,

2. Open YourProjectName.csproj file, and look for this section:

   <ItemGroup>                                            
       <Compile Include="ExistingClass1.cs" />                     
       <Compile Include="ExistingClass2.cs" />                                 
       ...
       <Compile Include="Properties\AssemblyInfo.cs" />     
   </ItemGroup>
   

1. Check that the .cs file that you want to add is in the project folder (same folder as all the existing classes in the solution).

2. Add an entry inside as below, save and open the project.

   <Compile Include="OtherClassFile.cs" /> 
   

Your class, will now appear and behave as part of the project. No using is needed. This can be done multiple files in one shot.

Change MySQL character:

Client

default-character-set=utf8

mysqld

character_set_server=utf8

We should not write default-character-set=utf8 in mysqld, because that could result in an error like:

start: Job failed to start

At last:

Just a piece of advice. Instead of writing

for (int i=0; i=((Main.size())-1); i++) {
   cout << Main[i] << '\n';
}

as suggested above, write a:

for (vector<double>::iterator it=Main.begin(); it!=Main.end(); it++) {
   cout << *it << '\n';
}

to use iterators. If you have C++11 support, you can declare i as auto i=Main.begin() (just a handy shortcut though)

This avoids the nasty one-position-out-of-bound error caused by leaving out a -1 unintentionally.

Type in cmd.exe Powershell -Help and see the examples.

A slight generalization to Alexander's answer - np.reshape can take -1 as an argument, meaning "total array size divided by product of all other listed dimensions":

e.g. to flatten all but the last dimension:

>>> arr = numpy.zeros((50,100,25))
>>> new_arr = arr.reshape(-1, arr.shape[-1])
>>> new_arr.shape
# (5000, 25)

You can send your data like the "POST" request through the "HEADERS".

Something like this:

$.ajax({
   url: "htttp://api.com/entity/list($body)",
   type: "GET",
   headers: ['id1':1, 'id2':2, 'id3':3],
   data: "",
   contentType: "text/plain",
   dataType: "json",
   success: onSuccess,
   error: onError
});

By using the _MSC_VER macro.

In Python 3, urllib2 was replaced by two in-built modules named urllib.request and urllib.error

Adapted from source

So replace this:

import urllib2

With this:

import urllib.request as urllib2

Previous answers seem to be outdated.

Java's File.renameTo() is probably the easiest solution for API 7, and seems to work fine. Be carefull IT DOES NOT THROW EXCEPTIONS, but returns true/false!!!

Note that there seem to be problems with it in previous versions (same as NIO).

If you need to use a previous version, check here.

Here's an example for API7:

File f1= new File("C:\\Users\\.....\\foo");
File f2= new File("C:\\Users\\......\\foo.old");
System.err.println("Result of move:"+f1.renameTo(f2));

Alternatively:

System.err.println("Move:" +f1.toURI() +"--->>>>"+f2.toURI());
Path b1=Files.move(f1.toPath(),  f2.toPath(), StandardCopyOption.ATOMIC_MOVE ,StandardCopyOption.REPLACE_EXISTING ););
System.err.println("Move: RETURNS:"+b1);

Try this from different folder:

sudo tar -cvjSf folder.tar.bz2 folder/*

Easy in your conf/main.php. This is my example with bootstrap. You can see that here

Since I was helped with my project by the answer above (I asked a duplicate question and was referred here), I am submitting an answer (my test code) for bracket notation when nesting within the var:

I know this is an old question, but it took me some time to sort this out given the sparse Angular documentation. The RouteProvider and routeParams is the way to go. The route wires up the URL to your Controller/View and the routeParams can be passed into the controller.

Check out the Angular seed project. Within the app.js you'll find an example for the route provider. To use params simply append them like this:

$routeProvider.when('/view1/:param1/:param2', {
    templateUrl: 'partials/partial1.html',    
    controller: 'MyCtrl1'
});

Then in your controller inject $routeParams:

.controller('MyCtrl1', ['$scope','$routeParams', function($scope, $routeParams) {
  var param1 = $routeParams.param1;
  var param2 = $routeParams.param2;
  ...
}]);

With this approach you can use params with a url such as: "http://www.example.com/view1/param1/param2"

I think ForkJoinPool and related enhancement to Executor Framework is an important addition in Java 7.

yourList = ["a", "b", "a", "c", "c", "a", "c"]

expected outputs {a: 3, b: 1,c:3}

duplicateFrequencies = {}
for i in set(yourList):
    duplicateFrequencies[i] = yourList.count(i)

Cheers!! Reference

The caller and the callee need to use the same convention at the point of invokation - that's the only way it could reliably work. Both the caller and the callee follow a predefined protocol - for example, who needs to clean up the stack. If conventions mismatch your program runs into undefined behavior - likely just crashes spectacularly.

This is only required per invokation site - the calling code itself can be a function with any calling convention.

You shouldn't notice any real difference in performance between those conventions. If that becomes a problem you usually need to make less calls - for example, change the algorithm.

In my case, the folder which served the files was a symbolic link to another folder, made with

ln -sf /origin /var/www/destination

Even though the permissions (user and group) where correct on the destination folder (the symbolic link), I still had the error because Nginx needed to have permissions to the origin folder whole's hierarchy as well.

%...% operators

%>% has no builtin meaning but the user (or a package) is free to define operators of the form %whatever% in any way they like. For example, this function will return a string consisting of its left argument followed by a comma and space and then it's right argument.

"%,%" <- function(x, y) paste0(x, ", ", y)

# test run

"Hello" %,% "World"
## [1] "Hello, World"

The base of R provides %*% (matrix mulitiplication), %/% (integer division), %in% (is lhs a component of the rhs?), %o% (outer product) and %x% (kronecker product). It is not clear whether %% falls in this category or not but it represents modulo.

expm The R package, expm, defines a matrix power operator %^%. For an example see Matrix power in R .

operators The operators R package has defined a large number of such operators such as %!in% (for not %in%). See http://cran.r-project.org/web/packages/operators/operators.pdf

igraph This package defines %--% , %->% and %<-% to select edges.

lubridate This package defines %m+% and %m-% to add and subtract months and %--% to define an interval. igraph also defines %--% .

Pipes

magrittr In the case of %>% the magrittr R package has defined it as discussed in the magrittr vignette. See http://cran.r-project.org/web/packages/magrittr/vignettes/magrittr.html

magittr has also defined a number of other such operators too. See the Additional Pipe Operators section of the prior link which discusses %T>%, %<>% and %$% and http://cran.r-project.org/web/packages/magrittr/magrittr.pdf for even more details.

dplyr The dplyr R package used to define a %.% operator which is similar; however, it has been deprecated and dplyr now recommends that users use %>% which dplyr imports from magrittr and makes available to the dplyr user. As David Arenburg has mentioned in the comments this SO question discusses the differences between it and magrittr's %>% : Differences between %.% (dplyr) and %>% (magrittr)

pipeR The R package, pipeR, defines a %>>% operator that is similar to magrittr's %>% and can be used as an alternative to it. See http://renkun.me/pipeR-tutorial/

The pipeR package also has defined a number of other such operators too. See: http://cran.r-project.org/web/packages/pipeR/pipeR.pdf

postlogic The postlogic package defined %if% and %unless% operators.

wrapr The R package, wrapr, defines a dot pipe %.>% that is an explicit version of %>% in that it does not do implicit insertion of arguments but only substitutes explicit uses of dot on the right hand side. This can be considered as another alternative to %>%. See https://winvector.github.io/wrapr/articles/dot_pipe.html

Bizarro pipe. This is not really a pipe but rather some clever base syntax to work in a way similar to pipes without actually using pipes. It is discussed in http://www.win-vector.com/blog/2017/01/using-the-bizarro-pipe-to-debug-magrittr-pipelines-in-r/ The idea is that instead of writing:

1:8 %>% sum %>% sqrt
## [1] 6

one writes the following. In this case we explicitly use dot rather than eliding the dot argument and end each component of the pipeline with an assignment to the variable whose name is dot (.) . We follow that with a semicolon.

1:8 ->.; sum(.) ->.; sqrt(.)
## [1] 6

Update Added info on expm package and simplified example at top. Added postlogic package.

You can call a controller action from a JavaScript function but not vice-versa. How would the server know which client to target? The server simply responds to requests.

An example of calling a controller action from JavaScript (using the jQuery JavaScript library) in the response sent to the client.

$.ajax({
           type: "POST",
           url: "/Controller/Action", // the URL of the controller action method
           data: null, // optional data
           success: function(result) {
                // do something with result
           },                
           error : function(req, status, error) {
                // do something with error   
           }
       });

when I use the function

select dbo.decode(10>1 ,'yes' ,'no')

then say syntax error near '>'

Unfortunately, that does not get you around having the CASE clause in the SQL, since you would need it to convert the logical expression to a bit parameter to match the type of the first function argument:

create function decode(@var1 as bit, @var2 as nvarchar(100), @var3 as nvarchar(100))
returns nvarchar(100)
begin
return case when @var1 = 1 then @var2 else @var3 end;
end;

select dbo.decode(case when 10 > 1 then 1 else 0 end, 'Yes', 'No');

It's called a Favicon, have a read.

<link rel="shortcut icon" href="http://www.example.com/myicon.ico"/>

You can use this neat tool to generate cross-browser compatible Favicons.

Although I am not sure if this is the result you expect, you can save your DataFrame in png by plotting the DataFrame with Seaborn Heatmap with annotations on, like this:

http://stanford.edu/~mwaskom/software/seaborn/generated/seaborn.heatmap.html#seaborn.heatmap

It works right away with a Pandas Dataframe. You can look at this example: Efficiently ploting a table in csv format using Python

You might want to change the colormap so it displays a white background only.

Hope this helps.

I solved it 100% I had this problem with gulp version: 3.5.6.

You should clean the package-lock.js and then run npm install and It worked form

Here is what I learned: PYTHONPATH is a directory to add to the Python import search path "sys.path", which is made up of current dir. CWD, PYTHONPATH, standard and shared library, and customer library. For example:

% python3 -c "import sys;print(sys.path)"
['', 
'/home/username/Documents/DjangoTutorial/mySite', 
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']

where the first path '' denotes the current dir., the 2nd path is via

%export PYTHONPATH=/home/username/Documents/DjangoTutorial/mySite 

which can be added to ~/.bashrc to make it permanent, and the rest are Python standard and dynamic shared library plus third-party library such as django.

As said not to mess with PYTHONHOME, even setting it to '' or 'None' will cause python3 shell to stop working:

% export PYTHONHOME=''
% python3
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'

Current thread 0x00007f18a44ff740 (most recent call first):
Aborted (core dumped)

Note that if you start a Python script, the CWD will be the script's directory. For example:

username@bud:~/Documents/DjangoTutorial% python3 mySite/manage.py runserver
==== Printing sys.path ====
/home/username/Documents/DjangoTutorial/mySite # CWD is where manage.py resides
/usr/lib/python3.6
/usr/lib/python3.6/lib-dynload
/usr/local/lib/python3.6/dist-packages
/usr/lib/python3/dist-packages

You can also append a path to sys.path at run-time: Suppose you have a file Fibonacci.py in ~/Documents/Python directory:

username@bud:~/Documents/DjangoTutorial% python3 
>>> sys.path.append("/home/username/Documents")
>>> print(sys.path)
['', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', 
'/home/username/Documents']
>>> from Python import Fibonacci as fibo

or via

% PYTHONPATH=/home/username/Documents:$PYTHONPATH
% python3
>>> print(sys.path)
['', 
'/home/username/Documents', '/home/username/Documents/DjangoTutorial/mySite', 
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']
>>> from Python import Fibonacci as fibo

So what are you doing is with append and concat is almost equivalent. The difference is the empty DataFrame. For some reason this causes a big slowdown, not sure exactly why, will have to look at some point. Below is a recreation of basically what you did.

I almost always use concat (though in this case they are equivalent, except for the empty frame); if you don't use the empty frame they will be the same speed.

In [17]: df1 = pd.DataFrame(dict(A = range(10000)),index=pd.date_range('20130101',periods=10000,freq='s'))

In [18]: df1
Out[18]: 
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 10000 entries, 2013-01-01 00:00:00 to 2013-01-01 02:46:39
Freq: S
Data columns (total 1 columns):
A    10000  non-null values
dtypes: int64(1)

In [19]: df4 = pd.DataFrame()

The concat

In [20]: %timeit pd.concat([df1,df2,df3])
1000 loops, best of 3: 270 us per loop

This is equavalent of your append

In [21]: %timeit pd.concat([df4,df1,df2,df3])
10 loops, best of 

 3: 56.8 ms per loop

I needed this functionality for multiple read more area's on one page implementing this into a Wordpress shortcode I ran into the same problem.

Design technically all of the read more span's on the page have a fixed height. And I wanted to be able to expand them separately to an auto height with a toggle. First click: 'expand to full height of text span', second click: 'collapse back to default height of 70px'

Html

 <span class="read-more" data-base="70" data-height="null">
     /* Lots of text determining the height of this span */
 </span>
 <button data-target='read-more'>Read more</button>

CSS

span.read-more {
    position:relative;
    display:block;
    overflow:hidden;
}

So above this looks very simple the data-base attribute I need to set the fixed height needed. The data-height attribute I used to store the actual (dynamic) height of the element.

The jQuery part

jQuery(document).ready(function($){

  $.fn.clickToggle = function(func1, func2) {
      var funcs = [func1, func2];
      this.data('toggleclicked', 0);
      this.click(function() {
          var data = $(this).data();
          var tc = data.toggleclicked;
          $.proxy(funcs[tc], this)();
          data.toggleclicked = (tc + 1) % 2;
      });
      return this;
  };

    function setAttr_height(key) {
        $(key).each(function(){
            var setNormalHeight = $(this).height();
            $(this).attr('data-height', setNormalHeight);
            $(this).css('height', $(this).attr('data-base') + 'px' );
        });
    }
    setAttr_height('.read-more');

    $('[data-target]').clickToggle(function(){
        $(this).prev().animate({height: $(this).prev().attr('data-height')}, 200);
    }, function(){
        $(this).prev().animate({height: $(this).prev().attr('data-base')}, 200);
    });

});

First I've used a clickToggle function for my first and second click. The second function is more important: setAttr_height() All of the .read-more elements have their actual heights set on page load in the base-height attribute. After that the base height is set through the jquery css function.

With both of our attributes set we now can toggle between them in a smooth way. Only chang the data-base to your desired (fixed)height and switch the .read-more class for your own ID

You can all see it working in a fiddle FIDDLE

No jQuery UI needed

I would like to extend the answer of @dzintars about the Cygwin version of pkg-config in that focus how should one use it properly with CMake, because I see various comments about CMake in this topic.

I have experienced many troubles with CMake + Cygwin's pkg-config and I want to share my experience how to avoid them.

1. The symlink C:/Cygwin64/bin/pkg-config -> pkgconf.exe does not work in Windows console.

It is not a native Windows .lnk symlink and it won't be callable in Windows console cmd.exe even if you add ".;" to your %PATHEXT% (see https://www.mail-archive.com/[email protected]/msg104088.html).

It won't work from CMake, because CMake calls pkg-config with the method execute_process() (FindPkgConfig.cmake) which opens a new cmd.exe.

Solution: Add -DPKG_CONFIG_EXECUTABLE=C:/Cygwin64/bin/pkgconf.exe to the CMake command line (or set it in CMakeLists.txt).

2. Cygwin's pkg-config recognizes only Cygwin paths in PKG_CONFIG_PATH (no Windows paths).

For example, on my system the .pc files are located in C:\Cygwin64\usr\x86_64-w64-mingw32\sys-root\mingw\lib\pkgconfig. The following three paths are valid, but only path C works in PKG_CONFIG_PATH:

• A) c:/Cygwin64/usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig - does not work.
• B) /c/cygdrive/usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig - does not work.
• C) /usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig - works.

Solution: add .pc files location always as a Cygwin path into PKG_CONFIG_PATH.

3) CMake converts forward slashes to backslashes in PKG_CONFIG_PATH on Cygwin.

It happens due to the bug https://gitlab.kitware.com/cmake/cmake/-/issues/21629. It prevents using the workaround described in [2].

Solution: manually update the function _pkg_set_path_internal() in the file C:/Program Files/CMake/share/cmake-3.x/Modules/FindPkgConfig.cmake. Comment/remove the line:

file(TO_NATIVE_PATH "${_pkgconfig_path}" _pkgconfig_path)

4) CMAKE_PREFIX_PATH, CMAKE_FRAMEWORK_PATH, CMAKE_APPBUNDLE_PATH have no effect on pkg-config in Cygwin.

Reason: the bug https://gitlab.kitware.com/cmake/cmake/-/issues/21775.

Solution: Use only PKG_CONFIG_PATH as an environment variable if you run CMake builds on Cygwin. Forget about CMAKE_PREFIX_PATH, CMAKE_FRAMEWORK_PATH, CMAKE_APPBUNDLE_PATH.

In the spirit of functional programming, let's make our components a bit easier to work with by using abstractions.

// converts components into mappable functions
var mappable = function(component){
  return function(x, i){
    return component({key: i}, x);
  }
}

// maps on 2-dimensional arrays
var map2d = function(m1, m2, xss){
  return xss.map(function(xs, i, arr){
    return m1(xs.map(m2), i, arr);
  });
}

var td = mappable(React.DOM.td);
var tr = mappable(React.DOM.tr);
var th = mappable(React.DOM.th);

Now we can define our render like this:

render: function(){
  return (
    <table>
      <thead>{this.props.titles.map(th)}</thead>
      <tbody>{map2d(tr, td, this.props.rows)}</tbody>
    </table>
  );
}

jsbin

An alternative to our map2d would be a curried map function, but people tend to shy away from currying.

This is another C example of where the same syntax has different meanings (in different places). While one might be able to argue that the syntax should be different for these two cases, it is what it is. The idea is that not that it is "not allowed" but that the second thing means something different (it means "pointer assignment").

The following doesn't work for JDK 1.7.0.07:

frame.setLocationRelativeTo(null);

It puts the top left corner at the center - not the same as centering the window. The other one doesn't work either, involving frame.getSize() and dimension.getSize():

Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize();
int x = (int) ((dimension.getWidth() - frame.getWidth()) / 2);
int y = (int) ((dimension.getHeight() - frame.getHeight()) / 2);
frame.setLocation(x, y);

The getSize() method is inherited from the Component class, and therefore frame.getSize returns the size of the window as well. Thus subtracting half the vertical and horizontal dimensions from the vertical and horizontal dimensions, to find the x,y coordinates of where to place the top-left corner, gives you the location of the center point, which ends up centering the window as well. However, the first line of the above code is useful, "Dimension...". Just do this to center it:

Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize();
JLabel emptyLabel = new JLabel("");
emptyLabel.setPreferredSize(new Dimension( (int)dimension.getWidth() / 2, (int)dimension.getHeight()/2 ));
frame.getContentPane().add(emptyLabel, BorderLayout.CENTER);
frame.setLocation((int)dimension.getWidth()/4, (int)dimension.getHeight()/4);

The JLabel sets the screen-size. It's in FrameDemo.java available on the java tutorials at the Oracle/Sun site. I set it to half the screen size's height/width. Then, I centered it by placing the top left at 1/4 of the screen size's dimension from the left, and 1/4 of the screen size's dimension from the top. You can use a similar concept.

I think what you want to do is actually pass by reference (pointer) to the function-- create a new environment (which are passed by reference to functions) with the list added to it:

listptr=new.env(parent=globalenv())
listptr$list=mylist

#Then the function is modified as:
lPtrAppend <- function(lstptr, obj) {
    lstptr$list[[length(lstptr$list)+1]] <- obj
}

Now you are only modifying the existing list (not creating a new one)

Maybe not the best solution, (will rewrite history) but you could also do git reset --hard <hash of detached head commit>.

My immediate solution (since I couldn't find the ASP.NET worker process) was to give write (that is, Modify) permission to IIS_IUSRS. This worked. I seem to recall that in WinXP I had to specifically given the ASP.NET worker process write permission to accomplish this. Maybe my memory is faulty, but anyway...

@DraganRadivojevic wrote that he thought this was dangerous from a security viewpoint. I do not disagree, but since this was my workstation and not a network server, it seemed relatively safe. In any case, his answer is better and is what I finally settled on after chasing down a fail-path due to not specifying the correct domain for the AppPool user.

You cannot open Java Applets (nor any other NPAPI plugin) in Microsoft Edge - they aren't supported and won't be added in the future.

Further you should be aware that in the next release of Google Chrome (v45 - due September 2015) NPAPI plugins will also no longer be supported.

Work-arounds

There are a couple of things that you can do:

Use Internet Explorer 11
You will find that in Windows 10 you will already have Internet Explorer 11 installed. IE 11 continues to support NPAPI (incl Java Applets). IE11 is squirrelled away (c:\program files\internet explorer\iexplore.exe). Just pin this exe to your task bar for easy access.

Use FireFox
You can also install and use a Firefox 32-bit Extended Support Release in Win10. Firefox have disabled NPAPI by default, but this can be overridden. This will only be supported until early 2018.

In my case I setted a old workspace and it was the problem.

Try to set a new folder for workspace

As there are different paths for different versions. Here is a generic solution:

Find the path...

1. Enter adb shell in command line.
2. Then ls and Enter.

Now you'll see the files and directories of Android device. Now with combination of ls and cd dirName find the path to the Internal or External storage.

In the root directory, the directories names will be like mnt, sdcard, emulator0, etc

Example: adb push file.txt mnt/sdcard/myDir/Projects/

When running python (cpython) on windows the <built-in function system> os.system will execute under the curtains _wsystem while if you're using a non-windows os, it'll use system.

On contrary, Popen should use CreateProcess on windows and _posixsubprocess.fork_exec in posix-based operating-systems.

That said, an important piece of advice comes from os.system docs, which says:

The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function. See the Replacing Older Functions with the subprocess Module section in the subprocess documentation for some helpful recipes.

you can use the views *_DEPENDENCIES, for example:

SELECT owner, NAME
  FROM dba_dependencies
 WHERE referenced_owner = :table_owner
   AND referenced_name = :table_name
   AND TYPE IN ('PACKAGE', 'PACKAGE BODY')

A little hacky, but I created an array called "console", and anytime I wanted to output to console I pushed to the array. Then whenever I wanted to see the actual output, I just returned console instead of whatever I was returning before.

    //return 'console' //uncomment to output console
    return "actual output";
}

The concatenation operator + is a binary infix operator which, when applied to lists, returns a new list containing all the elements of each of its two operands. The list.append() method is a mutator on list which appends its single object argument (in your specific example the list c) to the subject list. In your example this results in c appending a reference to itself (hence the infinite recursion).

An alternative to '+' concatenation

The list.extend() method is also a mutator method which concatenates its sequence argument with the subject list. Specifically, it appends each of the elements of sequence in iteration order.

An aside

Being an operator, + returns the result of the expression as a new value. Being a non-chaining mutator method, list.extend() modifies the subject list in-place and returns nothing.

Arrays

I've added this due to the potential confusion which the Abel's answer above may cause by mixing the discussion of lists, sequences and arrays. Arrays were added to Python after sequences and lists, as a more efficient way of storing arrays of integral data types. Do not confuse arrays with lists. They are not the same.

From the array docs:

Arrays are sequence types and behave very much like lists, except that the type of objects stored in them is constrained. The type is specified at object creation time by using a type code, which is a single character.

I had the same issue during building my app in AppVeyor.

• Download https://curl.haxx.se/ca/cacert.pem to c:\php

Here's a solution using a lineJoin to round the corners. Works if you just need a solid shape but not so much if you need a thin border that's smaller than the border radius.

    function roundedRect(ctx, options) {

        ctx.strokeStyle = options.color;
        ctx.fillStyle = options.color;
        ctx.lineJoin = "round";
        ctx.lineWidth = options.radius;

        ctx.strokeRect(
            options.x+(options.radius*.5),
            options.y+(options.radius*.5),
            options.width-options.radius,
            options.height-options.radius
        );

        ctx.fillRect(
            options.x+(options.radius*.5),
            options.y+(options.radius*.5),
            options.width-options.radius,
            options.height-options.radius
        );

        ctx.stroke();
        ctx.fill();

    }

    const canvas = document.getElementsByTagName("CANVAS")[0];
    let ctx = canvas.getContext('2d');

    roundedRect(ctx, {
        x: 10,
        y: 10,
        width: 200,
        height: 100,
        radius: 10,
        color: "red"
    });

Any approach should give you roughly same number. It is always a good idea to allocate the heap using -X..m -X..x for all generations. You can then guarantee and also do ps to see what parameters were passed and hence being used.

For actual memory usages, you can roughly compare VIRT (allocated and shared) and RES (actual used) compare against the jstat values as well:

For Java 8, see jstat for these values actually mean. Assuming you run a simple class with no mmap or file processing.

Max:

   3433472 + 512 + 512 + 67072 + 6867968 + 1083392 + 1048576 = 12 GB

(roughly close and below to VIRT memory)

Max(Min, Used):

215040 + 512 + 512 + 67072 + 430080  + 39680    +  4864  = ~ 1GB

(roughly close to RES memory)

"Don't quote me on this" but VIRT mem is roughly close to or more than Max memory allocated but as long as memory being used is free/available in physical memory, JVM does not throw memory exception. In fact, max memory is not even checked against physical memory on JVM startup even with swap off on OS. A better explanation of what Virtual memory really used by a Java process is discussed here.

Bubble sort is definitely the winner The next one on the radar would be insertion sort.

What is SQL JOIN ?

SQL JOIN is a method to retrieve data from two or more database tables.

What are the different SQL JOINs ?

There are a total of five JOINs. They are :

  1. JOIN or INNER JOIN
  2. OUTER JOIN

     2.1 LEFT OUTER JOIN or LEFT JOIN
     2.2 RIGHT OUTER JOIN or RIGHT JOIN
     2.3 FULL OUTER JOIN or FULL JOIN

  3. NATURAL JOIN
  4. CROSS JOIN
  5. SELF JOIN

1. JOIN or INNER JOIN :

In this kind of a JOIN, we get all records that match the condition in both tables, and records in both tables that do not match are not reported.

In other words, INNER JOIN is based on the single fact that: ONLY the matching entries in BOTH the tables SHOULD be listed.

Note that a JOIN without any other JOIN keywords (like INNER, OUTER, LEFT, etc) is an INNER JOIN. In other words, JOIN is a Syntactic sugar for INNER JOIN (see: Difference between JOIN and INNER JOIN).

2. OUTER JOIN :

OUTER JOIN retrieves

Either, the matched rows from one table and all rows in the other table Or, all rows in all tables (it doesn't matter whether or not there is a match).

There are three kinds of Outer Join :

2.1 LEFT OUTER JOIN or LEFT JOIN

This join returns all the rows from the left table in conjunction with the matching rows from the right table. If there are no columns matching in the right table, it returns NULL values.

2.2 RIGHT OUTER JOIN or RIGHT JOIN

This JOIN returns all the rows from the right table in conjunction with the matching rows from the left table. If there are no columns matching in the left table, it returns NULL values.

2.3 FULL OUTER JOIN or FULL JOIN

This JOIN combines LEFT OUTER JOIN and RIGHT OUTER JOIN. It returns rows from either table when the conditions are met and returns NULL value when there is no match.

In other words, OUTER JOIN is based on the fact that: ONLY the matching entries in ONE OF the tables (RIGHT or LEFT) or BOTH of the tables(FULL) SHOULD be listed.

Note that `OUTER JOIN` is a loosened form of `INNER JOIN`.

3. NATURAL JOIN :

It is based on the two conditions :

1. the JOIN is made on all the columns with the same name for equality.
2. Removes duplicate columns from the result.

This seems to be more of theoretical in nature and as a result (probably) most DBMS don't even bother supporting this.

4. CROSS JOIN :

It is the Cartesian product of the two tables involved. The result of a CROSS JOIN will not make sense in most of the situations. Moreover, we won't need this at all (or needs the least, to be precise).

5. SELF JOIN :

It is not a different form of JOIN, rather it is a JOIN (INNER, OUTER, etc) of a table to itself.

JOINs based on Operators

Depending on the operator used for a JOIN clause, there can be two types of JOINs. They are

1. Equi JOIN
2. Theta JOIN

1. Equi JOIN :

For whatever JOIN type (INNER, OUTER, etc), if we use ONLY the equality operator (=), then we say that the JOIN is an EQUI JOIN.

2. Theta JOIN :

This is same as EQUI JOIN but it allows all other operators like >, <, >= etc.

Many consider both EQUI JOIN and Theta JOIN similar to INNER, OUTER etc JOINs. But I strongly believe that its a mistake and makes the ideas vague. Because INNER JOIN, OUTER JOIN etc are all connected with the tables and their data whereas EQUI JOIN and THETA JOIN are only connected with the operators we use in the former.

Again, there are many who consider NATURAL JOIN as some sort of "peculiar" EQUI JOIN. In fact, it is true, because of the first condition I mentioned for NATURAL JOIN. However, we don't have to restrict that simply to NATURAL JOINs alone. INNER JOINs, OUTER JOINs etc could be an EQUI JOIN too.

Let me answer this question thoroughly, because it's been a source of pain for me for several years and very few people really understand the problem and why it's important for it to be solved. If I were at all responsible for the CSS spec I'd be embarrassed, frankly, for having not addressed this in the last decade.

The Problem

You need to insert markup into an HTML document, and it needs to look a specific way. Furthermore, you do not own this document, so you cannot change existing style rules. You have no idea what the style sheets could be, or what they may change to.

Use cases for this are when you are providing a displayable component for unknown 3rd party websites to use. Examples of this would be:

1. An ad tag
2. Building a browser extension that inserts content
3. Any type of widget

Simplest Fix

Put everything in an iframe. This has it's own set of limitations:

1. Cross Domain limitations: Your content will not have access to the original document at all. You cannot overlay content, modify the DOM, etc.
2. Display Limitations: Your content is locked inside of a rectangle.

If your content can fit into a box, you can get around problem #1 by having your content write an iframe and explicitly set the content, thus skirting around the issue, since the iframe and document will share the same domain.

CSS Solution

I've search far and wide for the solution to this, but there are unfortunately none. The best you can do is explicitly override all possible properties that can be overridden, and override them to what you think their default value should be.

Even when you override, there is no way to ensure a more targeted CSS rule won't override yours. The best you can do here is to have your override rules target as specifically as possible and hope the parent document doesn't accidentally best it: use an obscure or random ID on your content's parent element, and use !important on all property value definitions.

The difference is that, for example, a

List<HashMap<String,String>>

is a

List<? extends Map<String,String>>

but not a

List<Map<String,String>>

So:

void withWilds( List<? extends Map<String,String>> foo ){}
void noWilds( List<Map<String,String>> foo ){}

void main( String[] args ){
    List<HashMap<String,String>> myMap;

    withWilds( myMap ); // Works
    noWilds( myMap ); // Compiler error
}

You would think a List of HashMaps should be a List of Maps, but there's a good reason why it isn't:

Suppose you could do:

List<HashMap<String,String>> hashMaps = new ArrayList<HashMap<String,String>>();

List<Map<String,String>> maps = hashMaps; // Won't compile,
                                          // but imagine that it could

Map<String,String> aMap = Collections.singletonMap("foo","bar"); // Not a HashMap

maps.add( aMap ); // Perfectly legal (adding a Map to a List of Maps)

// But maps and hashMaps are the same object, so this should be the same as

hashMaps.add( aMap ); // Should be illegal (aMap is not a HashMap)

So this is why a List of HashMaps shouldn't be a List of Maps.

Or use awk instead:

awk '/null/ { counter++; printf("%s%s%i\n",$0, " - Line number: ", NR)} END {print "Total null count: " counter}' file

\S matches anything but a whitespace, according to this reference.

This solution works for multiline:

After following several articles, and requiring a function that would automatically scale the text and adjust the line count to best fit within the given label size, I wrote a function myself. (ie. a short string would fit nicely on one line and use a large amount of the label frame, whereas a long strong would automatically split onto 2 or 3 lines and adjust the size accordingly)

Feel free to re-use it and tweak as required. Make sure you call it after viewDidLayoutSubviews has finished so that the initial label frame has been set.

+ (void)setFontForLabel:(UILabel *)label withMaximumFontSize:(float)maxFontSize andMaximumLines:(int)maxLines {
    int numLines = 1;
    float fontSize = maxFontSize;
    CGSize textSize; // The size of the text
    CGSize frameSize; // The size of the frame of the label
    CGSize unrestrictedFrameSize; // The size the text would be if it were not restricted by the label height
    CGRect originalLabelFrame = label.frame;

    frameSize = label.frame.size;
    textSize = [label.text sizeWithAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize: fontSize]}];

    // Work out the number of lines that will need to fit the text in snug
    while (((textSize.width / numLines) / (textSize.height * numLines) > frameSize.width / frameSize.height) && (numLines < maxLines)) {
        numLines++;
    }

    label.numberOfLines = numLines;

    // Get the current text size
    label.font = [UIFont systemFontOfSize:fontSize];
    textSize = [label.text boundingRectWithSize:CGSizeMake(frameSize.width, CGFLOAT_MAX)
                                        options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
                                     attributes:@{NSFontAttributeName : label.font}
                                        context:nil].size;

    // Adjust the frame size so that it can fit text on more lines
    // so that we do not end up with truncated text
    label.frame = CGRectMake(label.frame.origin.x, label.frame.origin.y, label.frame.size.width, label.frame.size.width);

    // Get the size of the text as it would fit into the extended label size
    unrestrictedFrameSize = [label textRectForBounds:CGRectMake(0, 0, label.bounds.size.width, CGFLOAT_MAX) limitedToNumberOfLines:numLines].size;

    // Keep reducing the font size until it fits
    while (textSize.width > unrestrictedFrameSize.width || textSize.height > frameSize.height) {
        fontSize--;
        label.font = [UIFont systemFontOfSize:fontSize];
        textSize = [label.text boundingRectWithSize:CGSizeMake(frameSize.width, CGFLOAT_MAX)
                                            options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
                                         attributes:@{NSFontAttributeName : label.font}
                                            context:nil].size;
        unrestrictedFrameSize = [label textRectForBounds:CGRectMake(0, 0, label.bounds.size.width, CGFLOAT_MAX) limitedToNumberOfLines:numLines].size;
    }

    // Set the label frame size back to original
    label.frame = originalLabelFrame;
}

I was having the problem as a beginner..........

I answered a very similar question:

https://stackoverflow.com/a/15982217/1467082

You simply need to iterate over the series' .Points collection, and then you can assign the points' .Format.Fill.ForeColor.RGB value based on whatever criteria you need.

UPDATED

The code below will color the chart per the screenshot. This only assumes three colors are used. You can add additional case statements for other color values, and update the assignment of myColor to the appropriate RGB values for each.

Option Explicit
Sub ColorScatterPoints()
    Dim cht As Chart
    Dim srs As Series
    Dim pt As Point
    Dim p As Long
    Dim Vals$, lTrim#, rTrim#
    Dim valRange As Range, cl As Range
    Dim myColor As Long

    Set cht = ActiveSheet.ChartObjects(1).Chart
    Set srs = cht.SeriesCollection(1)

   '## Get the series Y-Values range address:
    lTrim = InStrRev(srs.Formula, ",", InStrRev(srs.Formula, ",") - 1, vbBinaryCompare) + 1
    rTrim = InStrRev(srs.Formula, ",")
    Vals = Mid(srs.Formula, lTrim, rTrim - lTrim)
    Set valRange = Range(Vals)

    For p = 1 To srs.Points.Count
        Set pt = srs.Points(p)
        Set cl = valRange(p).Offset(0, 1) '## assume color is in the next column.

        With pt.Format.Fill
            .Visible = msoTrue
            '.Solid  'I commented this out, but you can un-comment and it should still work
            '## Assign Long color value based on the cell value
            '## Add additional cases as needed.
            Select Case LCase(cl)
                Case "red"
                    myColor = RGB(255, 0, 0)
                Case "orange"
                    myColor = RGB(255, 192, 0)
                Case "green"
                    myColor = RGB(0, 255, 0)
            End Select

            .ForeColor.RGB = myColor

        End With
    Next


End Sub

This worked nicely for my needs ;) Hope someone can use it....

    public static Color FromName(String name)
    {
        var color_props= typeof(Colors).GetProperties();
        foreach (var c in color_props)
            if (name.Equals(c.Name, StringComparison.OrdinalIgnoreCase))
                return (Color)c.GetValue(new Color(), null);
        return Colors.Transparent;
    }

I usually use set_time_limit(30) within the main loop (so each loop iteration is limited to 30 seconds rather than the whole script).

I do this in multiple database update scripts, which routinely take several minutes to complete but less than a second for each iteration - keeping the 30 second limit means the script won't get stuck in an infinite loop if I am stupid enough to create one.

I must admit that my choice of 30 seconds for the limit is somewhat arbitrary - my scripts could actually get away with 2 seconds instead, but I feel more comfortable with 30 seconds given the actual application - of course you could use whatever value you feel is suitable.

Hope this helps!

req.query is the query string sent to the server, example /page?test=1, req.param is the parameters passed to the handler.

app.get('/user/:id', handler);, going to /user/blah, req.param.id would return blah;

The following XML-to-Python-dict snippet parses entities as well as attributes following this XML-to-JSON "specification". It is the most general solution handling all cases of XML.

from collections import defaultdict

    children = list(t)
    if children:
        dd = defaultdict(list)
        for dc in map(etree_to_dict, children):
            for k, v in dc.items():
                dd[k].append(v)
        d = {t.tag: {k:v[0] if len(v) == 1 else v for k, v in dd.items()}}
    if t.attrib:
        d[t.tag].update(('@' + k, v) for k, v in t.attrib.items())
    if t.text:
        text = t.text.strip()
        if children or t.attrib:
            if text:
              d[t.tag]['#text'] = text
        else:
            d[t.tag] = text
    return d

It is used:

from xml.etree import cElementTree as ET
e = ET.XML('''
<root>
  <e />
  <e>text</e>
  <e name="value" />
  <e name="value">text</e>
  <e> <a>text</a> <b>text</b> </e>
  <e> <a>text</a> <a>text</a> </e>
  <e> text <a>text</a> </e>
</root>
''')

from pprint import pprint
pprint(etree_to_dict(e))

The output of this example (as per above-linked "specification") should be:

{'root': {'e': [None,
                'text',
                {'@name': 'value'},
                {'#text': 'text', '@name': 'value'},
                {'a': 'text', 'b': 'text'},
                {'a': ['text', 'text']},
                {'#text': 'text', 'a': 'text'}]}}

Not necessarily pretty, but it is unambiguous, and simpler XML inputs result in simpler JSON. :)

Update

If you want to do the reverse, emit an XML string from a JSON/dict, you can use:

try:
  basestring
except NameError:  # python3
  basestring = str

def dict_to_etree(d):
    def _to_etree(d, root):
        if not d:
            pass
        elif isinstance(d, basestring):
            root.text = d
        elif isinstance(d, dict):
            for k,v in d.items():
                assert isinstance(k, basestring)
                if k.startswith('#'):
                    assert k == '#text' and isinstance(v, basestring)
                    root.text = v
                elif k.startswith('@'):
                    assert isinstance(v, basestring)
                    root.set(k[1:], v)
                elif isinstance(v, list):
                    for e in v:
                        _to_etree(e, ET.SubElement(root, k))
                else:
                    _to_etree(v, ET.SubElement(root, k))
        else:
            raise TypeError('invalid type: ' + str(type(d)))
    assert isinstance(d, dict) and len(d) == 1
    tag, body = next(iter(d.items()))
    node = ET.Element(tag)
    _to_etree(body, node)
    return ET.tostring(node)

pprint(dict_to_etree(d))

In SwiftUI, The simplest implementation would be,

struct MyTextField: View {
  var myPlaceHolder: String
  @Binding var text: String

  var underColor: Color
  var height: CGFloat

  var body: some View {
    VStack {
        TextField(self.myPlaceHolder, text: $text)
        .padding(.horizontal, 24)
        .font(.title)

        Rectangle().frame(height: self.height)
            .padding(.horizontal, 24).foregroundColor(self.underColor)
    }
  }
}

Usage:

MyTextField(myPlaceHolder: "PlaceHolder", text: self.$text, underColor: .red, height: 3)

The below JavaScript code sends "text" to be spoken/converted to mp3 audio to google cloud text-to-speech API and gets mp3 audio content as response back.

 var text-to-speech = function(state) {
    const url = 'https://texttospeech.googleapis.com/v1beta1/text:synthesize?key=GOOGLE_API_KEY'
    const data = {
      'input':{
         'text':'Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets.'
      },
      'voice':{
         'languageCode':'en-gb',
         'name':'en-GB-Standard-A',
         'ssmlGender':'FEMALE'
      },
      'audioConfig':{
      'audioEncoding':'MP3'
      }
     };
     const otherparam={
        headers:{
           "content-type":"application/json; charset=UTF-8"
        },
        body:JSON.stringify(data),
        method:"POST"
     };
    fetch(url,otherparam)
    .then(data=>{return data.json()})
    .then(res=>{console.log(res.audioContent); })
    .catch(error=>{console.log(error);state.onError(error)})
  };

Why python uses list of tuples instead dict?

In python, you cannot guarantee that the dictionary will be interpreted in the order you declared.

So, in mongo shell you could do .sort({'field1':1,'field2':1}) and the interpreter would sort field1 at first level and field 2 at second level.

If this syntax was used in python, there is a chance of sorting by field2 at first level. With tuple, there is no such risk.

.sort([("field1",pymongo.ASCENDING), ("field2",pymongo.DESCENDING)])

First, add the Material Design dependency.

implementation 'com.google.android.material:material:<version>'

To get the latest material design library version. check the official website github repository.

Current version is 1.2.0.

So, you have to add,

implementation 'com.google.android.material:material:1.2.0'

Then, you need to change the app theme to material theme by adding,

<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

in your style.xml. Dont forget to set the same theme in your application theme in your manifest file.

Based nodejs document, http://nodejs.org/api/stream.html#stream_event_finish, it should handle writableStream's finish event.

var writable = getWriteable();
var readable = getReadable();
readable.pipe(writable);
writable.on('finish', function(){ ... });

I would do the following.

Set the zero to NA.

 data[data==0] <- NA
 data

Delete the rows associated with NA.

 data2<-data[complete.cases(data),]

This is a problem related permission. Make sure that the current user has access to the folder which contains installation files.

If you are using webpack. This imports files automatically and exports as api namespace.

So no need to update on every file addition.

import camelCase from "lodash-es";
const requireModule = require.context("./", false, /\.js$/); // 
const api = {};

requireModule.keys().forEach(fileName => {
  if (fileName === "./index.js") return;
  const moduleName = camelCase(fileName.replace(/(\.\/|\.js)/g, ""));
  api[moduleName] = {
    ...requireModule(fileName).default
  };
});

export default api;

For Typescript users;

import { camelCase } from "lodash-es"
const requireModule = require.context("./folderName", false, /\.ts$/)

interface LooseObject {
  [key: string]: any
}

const api: LooseObject = {}

requireModule.keys().forEach(fileName => {
  if (fileName === "./index.ts") return
  const moduleName = camelCase(fileName.replace(/(\.\/|\.ts)/g, ""))
  api[moduleName] = {
    ...requireModule(fileName).default,
  }
})

export default api

Three important steps - How to Task Schedule an excel.xls(m) file

simply:

1. make sure the .vbs file is correct
2. set the Action tab correctly in Task Scheduler
3. don't turn on "Run whether user is logged on or not"

IN MORE DETAIL...

1. Here is an example .vbs file:

`

'   a .vbs file is just a text file containing visual basic code that has the extension renamed from .txt  to .vbs

'Write Excel.xls  Sheet's full path here
strPath = "C:\RodsData.xlsm" 

'Write the macro name - could try including module name
strMacro = "Update" '    "Sheet1.Macro2" 

'Create an Excel instance and set visibility of the instance
Set objApp = CreateObject("Excel.Application") 
objApp.Visible = True   '   or False 

'Open workbook; Run Macro; Save Workbook with changes; Close; Quit Excel
Set wbToRun = objApp.Workbooks.Open(strPath) 
objApp.Run strMacro     '   wbToRun.Name & "!" & strMacro 
wbToRun.Save 
wbToRun.Close 
objApp.Quit 

'Leaves an onscreen message!
MsgBox strPath & " " & strMacro & " macro and .vbs successfully completed!",         vbInformation 
'

`

2. In the Action tab (Task Scheduler):

set Program/script: = C:\Windows\System32\cscript.exe

set Add arguments (optional): = C:\MyVbsFile.vbs

3. Finally, don't turn on "Run whether user is logged on or not".

That should work.

Let me know!

Try this (demo):

.ui-autocomplete {
  position: absolute;
  top: 100%;
  left: 0;
  z-index: 1000;
  display: none;
  float: left;
  min-width: 160px;
  padding: 5px 0;
  margin: 2px 0 0;
  list-style: none;
  font-size: 14px;
  text-align: left;
  background-color: #ffffff;
  border: 1px solid #cccccc;
  border: 1px solid rgba(0, 0, 0, 0.15);
  border-radius: 4px;
  -webkit-box-shadow: 0 6px 12px rgba(0, 0, 0, 0.175);
  box-shadow: 0 6px 12px rgba(0, 0, 0, 0.175);
  background-clip: padding-box;
}

.ui-autocomplete > li > div {
  display: block;
  padding: 3px 20px;
  clear: both;
  font-weight: normal;
  line-height: 1.42857143;
  color: #333333;
  white-space: nowrap;
}

.ui-state-hover,
.ui-state-active,
.ui-state-focus {
  text-decoration: none;
  color: #262626;
  background-color: #f5f5f5;
  cursor: pointer;
}

.ui-helper-hidden-accessible {
  border: 0;
  clip: rect(0 0 0 0);
  height: 1px;
  margin: -1px;
  overflow: hidden;
  padding: 0;
  position: absolute;
  width: 1px;
}

I. In your build.gradle add latest appcompat library, at the time 24.2.1

dependencies {  
    compile 'com.android.support:appcompat-v7:X.X.X' 
    // where X.X.X version
}

II. Make your activity extend android.support.v7.app.AppCompatActivity and implement the DatePickerDialog.OnDateSetListener interface.

public class MainActivity extends AppCompatActivity  
    implements DatePickerDialog.OnDateSetListener {

III. Create your DatePickerDialog setting a context, the implementation of the listener and the start year, month and day of the date picker.

DatePickerDialog datePickerDialog = new DatePickerDialog(  
    context, MainActivity.this, startYear, starthMonth, startDay);

IV. Show your dialog on the click event listener of your button

((Button) findViewById(R.id.myButton))
    .setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        datePickerDialog.show();
    }
});

Strings are immutable, so you need to say

sInputString = sInputString("\"","");

not just the right side of the =

Try run this command it will create a *_limits.conf file under /etc/security/limits.d

echo "* soft nofile 102400" > /etc/security/limits.d/*_limits.conf && echo "* hard nofile 102400" >> /etc/security/limits.d/*_limits.conf

Just exit from terminal and login again and verify by ulimit -n it will set for * users

It looks as though the horizontal axis (Category Group) labels have very long values - there may not be room to display them all. I suggest changing the labels to have shorter values.

You can set the sort order for the Category Groups in the Category Group Properties - Sorting section - this may have been previously set; if not, I suggest using this to sort as desired.

You can wrap all tasks which can fail in block, and use ignore_errors: yes with that block.

tasks:
  - name: ls
    command: ls -la
  - name: pwd
    command: pwd

  - block:
    - name: ls non-existing txt file
      command: ls -la no_file.txt
    - name: ls non-existing pic
      command: ls -la no_pic.jpg
    ignore_errors: yes 

Read more about error handling in blocks here.

For Dense Layers:

output_size * (input_size + 1) == number_parameters 

For Conv Layers:

output_channels * (input_channels * window_size + 1) == number_parameters

Consider following example,

model = Sequential([
Conv2D(32, (3, 3), activation='relu', input_shape=input_shape),
Conv2D(64, (3, 3), activation='relu'),
Conv2D(128, (3, 3), activation='relu'),
Dense(num_classes, activation='softmax')
])

model.summary()

conv2d_2 (Conv2D)            (None, 220, 220, 64)      18496     
_________________________________________________________________
conv2d_3 (Conv2D)            (None, 218, 218, 128)     73856     
_________________________________________________________________
dense_9 (Dense)              (None, 218, 218, 10)      1290

Calculating params,

assert 32 * (3 * (3*3) + 1) == 896
assert 64 * (32 * (3*3) + 1) == 18496
assert 128 * (64 * (3*3) + 1) == 73856
assert num_classes * (128 + 1) == 1290

That error occurs when you try to call, with (), an object that is not callable.

A callable object can be a function or a class (that implements __call__ method). According to Python Docs:

object.__call__(self[, args...]): Called when the instance is “called” as a function

For example:

x = 1
print x()

x is not a callable object, but you are trying to call it as if it were it. This example produces the error:

TypeError: 'int' object is not callable

For better understaing of what is a callable object read this answer in another SO post.

In cell D2 and copied down:

=IF(COUNTIF($A$2:$A$5,C2)=0,"",VLOOKUP(C2,$A$2:$B$5,2,FALSE))

Or you could simply use

View.isShown()

You can also use the LocalPrintServer class. See: System.Printing.LocalPrintServer

    public List<string>  InstalledPrinters
    {
        get
        {
            return (from PrintQueue printer in new LocalPrintServer().GetPrintQueues(new[] { EnumeratedPrintQueueTypes.Local,
                EnumeratedPrintQueueTypes.Connections }).ToList()
                    select printer.Name).ToList(); 
        } 
    }

As stated in the docs: Classes within the System.Printing namespace are not supported for use within a Windows service or ASP.NET application or service.

Just add like this in case 1: like this

 case 0:
     list = DBAdpter.requestUserData(assosiatetoken);
     Collections.sort(list, byDate);
     for (int i = 0; i < list.size(); i++) {
         if (list.get(i).lastModifiedDate != null) {
             lv.setAdapter(new MyListAdapter(
                     getApplicationContext(), list));
         }
     }
     break;

and put this method at end of the your class

static final Comparator<All_Request_data_dto> byDate = new Comparator<All_Request_data_dto>() {
    SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss a");

    public int compare(All_Request_data_dto ord1, All_Request_data_dto ord2) {
        Date d1 = null;
        Date d2 = null;
        try {
            d1 = sdf.parse(ord1.lastModifiedDate);
            d2 = sdf.parse(ord2.lastModifiedDate);
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


        return (d1.getTime() > d2.getTime() ? -1 : 1);     //descending
    //  return (d1.getTime() > d2.getTime() ? 1 : -1);     //ascending
    }
};

I believe you want bgcolor. Something like this:

document.getElementById("button").bgcolor="#ffffff";

Here are a couple of demos that might help:

I'd recommend adopting Syslog severity levels: DEBUG, INFO, NOTICE, WARNING, ERROR, CRITICAL, ALERT, EMERGENCY.
See http://en.wikipedia.org/wiki/Syslog#Severity_levels

They should provide enough fine-grained severity levels for most use-cases and are recognized by existing log-parsers. While you have of course the freedom to only implement a subset, e.g. DEBUG, ERROR, EMERGENCY depending on your app's requirements.

Let's standardize on something that's been around for ages instead of coming up with our own standard for every different app we make. Once you start aggregating logs and are trying to detect patterns across different ones it really helps.

function Palindrome(str) {
  let forwardStr = str.toLowerCase().replace(/[\W_]/g, '');
  let reversedStr = forwardStr.split('').reverse().join();

  return forwardStr === reversedStr;
}
console.log(Palindrome('madam'));

Create a new file:

MyListener.java:

public interface MyListener {
    // you can define any parameter as per your requirement
    public void callback(View view, String result);
}

In your activity, implement the interface:

MyActivity.java:

public class MyActivity extends Activity implements MyListener {
   @override        
   public void onCreate(){
        MyButton m = new MyButton(this);
   }

    // method is invoked when MyButton is clicked
    @override
    public void callback(View view, String result) {   
        // do your stuff here
    }
}

In your custom class, invoke the interface when needed:

MyButton.java:

public class MyButton {
    MyListener ml;

    // constructor
    MyButton(MyListener ml) {
        //Setting the listener
        this.ml = ml;
    }

    public void MyLogicToIntimateOthers() {
        //Invoke the interface
        ml.callback(this, "success");
    }
}

Add following at start of cell and run it:

from IPython.display import clear_output
clear_output(wait=True)

Try This:

datagridview.Rows[currentRow].Cells[0];

As per this the default is 2 MB for your <Connector>.

maxPostSize = The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).

Edit Tomcat's server.xml. In the <Connector> element, add an attribute maxPostSize and set a larger value (in bytes) to increase the limit.

Having said that, if this is the issue, you should have got an exception on the lines of Post data too big in tomcat

For Further Info

Looks like you have a query that is taking longer than it should. From your stack trace and your code you should be able to determine exactly what query that is.

This type of timeout can have three causes;

1. There's a deadlock somewhere
2. The database's statistics and/or query plan cache are incorrect
3. The query is too complex and needs to be tuned

A deadlock can be difficult to fix, but it's easy to determine whether that is the case. Connect to your database with Sql Server Management Studio. In the left pane right-click on the server node and select Activity Monitor. Take a look at the running processes. Normally most will be idle or running. When the problem occurs you can identify any blocked process by the process state. If you right-click on the process and select details it'll show you the last query executed by the process.

The second issue will cause the database to use a sub-optimal query plan. It can be resolved by clearing the statistics:

exec sp_updatestats

If that doesn't work you could also try

dbcc freeproccache

You should not do this when your server is under heavy load because it will temporarily incur a big performace hit as all stored procs and queries are recompiled when first executed. However, since you state the issue occurs sometimes, and the stack trace indicates your application is starting up, I think you're running a query that is only run on occasionally. You may be better off by forcing SQL Server not to reuse a previous query plan. See this answer for details on how to do that.

I've already touched on the third issue, but you can easily determine whether the query needs tuning by executing the query manually, for example using Sql Server Management Studio. If the query takes too long to complete, even after resetting the statistics you'll probably need to tune it. For help with that, you should post the exact query in a new question.

Your for loop is not right, if you need the index in the for loop use:

for index, item in enumerate(emails):
    # whatever (but you can't remove element while iterating)

In your case, Bogdan solution is ok, but your data structure choice is not so good. Having to maintain these two lists with data from one related to data from the other at same index is clumsy.

A list of tupple (email, otherdata) may be better, or a dict with email as key.

You can also use Apache's ExceptionUtils.

Example:

import org.apache.log4j.Logger;


public class Test {

    static Logger logger = Logger.getLogger(Test.class);

    public static void main(String[] args) {

        try{
            String[] avengers = null;
            System.out.println("Size: "+avengers.length);
        } catch (NullPointerException e){
            logger.info(ExceptionUtils.getFullStackTrace(e));
        }
    }

}

Console output:

java.lang.NullPointerException
    at com.aimlessfist.avengers.ironman.Test.main(Test.java:11)

I agree that one shouldn't suppress warnings in classes or methods as one could overlook other, accidentally suppressed warnings. But IMHO it's absolutely reasonable to suppress a warning that affects only a single line of code.

@SuppressWarnings("unchecked")

You can also read the image using png package for example and plot it like a regular plot using grid.raster from the grid package.

```{r fig.width=1, fig.height=10,echo=FALSE}

img <- readPNG("path/to/your/image")
 grid.raster(img)
```

With this method you have full control of the size of you image.

In javascript there are no block-level scopes only function-level scopes:

Read this article about javaScript Scoping and Hoisting.

See how I debugged your code:

var deferred = $q.defer();
deferred.count = i;

console.log(deferred.count); // 0,1,2,3,4,5 --< all deferred objects

// some code

.success(function(data){
   console.log(deferred.count); // 5,5,5,5,5,5 --< only the last deferred object
   deferred.resolve(data);
})

• When you write var deferred= $q.defer(); inside a for loop it's hoisted to the top of the function, it means that javascript declares this variable on the function scope outside of the for loop.
• With each loop, the last deferred is overriding the previous one, there is no block-level scope to save a reference to that object.
• When asynchronous callbacks (success / error) are invoked, they reference only the last deferred object and only it gets resolved, so $q.all is never resolved because it still waits for other deferred objects.
• What you need is to create an anonymous function for each item you iterate.
• Since functions do have scopes, the reference to the deferred objects are preserved in a closure scope even after functions are executed.
• As #dfsq commented: There is no need to manually construct a new deferred object since $http itself returns a promise.

Solution with angular.forEach:

Here is a demo plunker: http://plnkr.co/edit/NGMp4ycmaCqVOmgohN53?p=preview

UploadService.uploadQuestion = function(questions){

    var promises = [];

    angular.forEach(questions , function(question) {

        var promise = $http({
            url   : 'upload/question',
            method: 'POST',
            data  : question
        });

        promises.push(promise);

    });

    return $q.all(promises);
}

My favorite way is to use Array#map:

Here is a demo plunker: http://plnkr.co/edit/KYeTWUyxJR4mlU77svw9?p=preview

UploadService.uploadQuestion = function(questions){

    var promises = questions.map(function(question) {

        return $http({
            url   : 'upload/question',
            method: 'POST',
            data  : question
        });

    });

    return $q.all(promises);
}

To trim a list in place without creating copies of it, use del:

>>> t = [1, 2, 3, 4, 5]
>>> # delete elements starting from index 4 to the end
>>> del t[4:]
>>> t
[1, 2, 3, 4]
>>> # delete elements starting from index 5 to the end
>>> # but the list has only 4 elements -- no error
>>> del t[5:]
>>> t
[1, 2, 3, 4]
>>> 

I had a similar problem and since I couldn't find a sufficient solution, I also created a serialization library for javascript: https://github.com/wavesoft/jbb (as a matter of fact it's a bit more, since it's mainly intended for bundling resources)

It is close to Binary-JSON but it adds a couple of additional features, such as metadata for the objects being encoded and some extra optimizations like data de-duplication, cross-referencing to other bundles and structure-level compression.

However there is a catch: In order to keep the bundle size small there are no type information in the bundle. Such information are provided in a separate "profile" that describes your objects for encoding and decoding. For optimization reasons this information is given in a form of script.

But you can make your life easier using the gulp-jbb-profile (https://github.com/wavesoft/gulp-jbb-profile) utility for generating the encodeing/decoding scripts from simple YAML object specifications like this:

# The 'Person' object has the 'age' and 'isOld'
# properties
Person:
  properties:
    - age
    - isOld

For example you can have a look on the jbb-profile-three profile. When you have your profile ready, you can use JBB like this:

var JBBEncoder = require('jbb/encode');
var MyEncodeProfile = require('profile/profile-encode');

// Create a new bundle
var bundle = new JBBEncoder( 'path/to/bundle.jbb' );

// Add one or more profile(s) in order for JBB
// to understand your custom objects
bundle.addProfile(MyEncodeProfile);

// Encode your object(s) - They can be any valid
// javascript object, or objects described in
// the profiles you added previously.

var p1 = new Person(77);
bundle.encode( p1, 'person' );

var people = [
        new Person(45),
        new Person(77),
        ...
    ];
bundle.encode( people, 'people' );

// Close the bundle when you are done
bundle.close();

And you can read it back like this:

var JBBDecoder = require('jbb/decode');
var MyDecodeProfile = require('profile/profile-decode');

// Instantiate a new binary decoder
var binaryLoader = new JBBDecoder( 'path/to/bundle' );

// Add your decoding profile
binaryLoader.addProfile( MyDecodeProfile );

// Add one or more bundles to load
binaryLoader.add( 'bundle.jbb' );

// Load and callback when ready
binaryLoader.load(function( error, database ) {

    // Your objects are in the database
    // and ready to use!
    var people = database['people'];

});

Swift 4.2 Extension method

extension UIImage {
    func toBase64() -> String? {
        guard let imageData = self.pngData() else { return nil }
        return imageData.base64EncodedString(options: Data.Base64EncodingOptions.lineLength64Characters)
    }
}

XCode 9.1 and Swift 4.0

//
// Convert UIImage to a base64 representation
//
class func convertImageToBase64(image: UIImage) -> String {
    let imageData = UIImagePNGRepresentation(image)!
    return imageData.base64EncodedString(options: Data.Base64EncodingOptions.lineLength64Characters)
}

//
// Convert a base64 representation to a UIImage
//
class func convertBase64ToImage(imageString: String) -> UIImage {
    let imageData = Data(base64Encoded: imageString, options: Data.Base64DecodingOptions.ignoreUnknownCharacters)!
    return UIImage(data: imageData)!
}

In case you have a .properties file or a .ini file

Actually in case if you have any file that has key value pairs like this:

someKey=someValue
someOtherKey=someOtherValue

You can import that into webpack by a npm module called properties-reader

I found this really helpful since I'm integrating react with Java Spring framework where there is already an application.properties file. This helps me to keep all config together in one place.

1. Import that from dependencies section in package.json

"properties-reader": "0.0.16"

2. Import this module into webpack.config.js on top

const PropertiesReader = require('properties-reader');

3. Read the properties file

const appProperties = PropertiesReader('Path/to/your/properties.file')._properties;

4. Import this constant as config

externals: { 'Config': JSON.stringify(appProperties) }

5. Use it as the same way as mentioned in the accepted answer

var Config = require('Config') fetchData(Config.serverUrl + '/Enterprises/...')

try: gsub('\\$', '', '$5.00$')

Add in activity

requestWindowFeature(Window.FEATURE_NO_TITLE);

and add your style.xml file with the following two lines:

<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>

create directory in /res/anim and create bottom_to_original.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="1500"
        android:fromYDelta="100%"
        android:toYDelta="1%" />
</set>

JAVA:

    LinearLayout ll = findViewById(R.id.ll);

    Animation animation;
    animation = AnimationUtils.loadAnimation(getApplicationContext(),
            R.anim.sample_animation);
    ll .setAnimation(animation);

With some version-control plug-ins, it means that the local file has not yet been shared with the version-control repository. (In my install, this includes plug-ins for CVS and git, but not Perforce.)

You can sometimes see a list of these decorations in the plug-in's preferences under Team/X/Label Decorations, where X describes the version-control system.

For example, for CVS, the list looks like this:

These adornments are added to the object icons provided by Eclipse. For example, here's a table of icons for the Java development environment.

Im my browser, this doesn't work at all. The tooltip field doesn't show a link, but <a href='#' onClick='alert('Hello World!')>The Link</a>. I'm using FF 3.6.12.

You'll have to do this by hand with JS and CSS. Begin here

Instead of the -f of make you might want to use the -C <path> option. This first changes the to the path '<path>', and then calles make there.

Example:

clean:
  rm -f ./*~ ./gmon.out ./core $(SRC_DIR)/*~ $(OBJ_DIR)/*.o
  rm -f ../svn-commit.tmp~
  rm -f $(BIN_DIR)/$(PROJECT)
  $(MAKE) -C gtest-1.4.0/make clean

Helpful method I created a while ago...

private static double round (double value, int precision) {
    int scale = (int) Math.pow(10, precision);
    return (double) Math.round(value * scale) / scale;
}

You can combine this all into one formula, but you need to use a regular IF first to find out if the VLOOKUP came back with something, then use your COUNTIF if it did.

=IF(ISERROR(VLOOKUP(B1,Sheet2!A1:A9,1,FALSE)),"Not there",COUNTIF(Sheet2!A1:A9,B1))

In this case, Sheet2-A1:A9 is the range I was searching, and Sheet1-B1 had the value I was looking for ("To retire" in your case).

>>> import datetime
>>> d = datetime.datetime.strptime('2011-06-09', '%Y-%m-%d')
>>> d.strftime('%b %d,%Y')
'Jun 09,2011'

In pre-2.5 Python, you can replace datetime.strptime with time.strptime, like so (untested): datetime.datetime(*(time.strptime('2011-06-09', '%Y-%m-%d')[0:6]))

I test your assertion in my infrastructure the IP address is not the problem the following works for me :

PS C:\Users\JPB> hostname

If you try to work accross a VPN you'd better have to have a look to the firewall settings on the way to your server. Installation and Configuration for Windows Remote Management can help you. The TCP port WinRM is waiting on are :

WinRM 1.1 and earlier: The default HTTP port is 80.

WinRM 2.0: The default HTTP port is 5985.

Edited : According to your error can you test this on youclient computer :

Set-Item WSMan:\localhost\Client\TrustedHosts *

It's quite simple.

All you need to do is:

• Right click above application tag and click on Generate
• Click on XML tag
• Click on user-permission
• Enter the name of your permission.

Here is my solution I've used in applications.

I disabled the body overflow and placed the entire website html inside container div's. The website containers have overflow and therefore the user may scroll the page as expected.

I then created a sibling div (#Prevent) with a higher z-index that covers the entire website. Since #Prevent has a higher z-index, it overlaps the website container. When #Prevent is visible the mouse is no longer hovering the website containers, so scrolling isn't possible.

You may of course place another div, such as your modal, with a higher z-index than #Prevent in the markup. This allows you to create pop-up windows that don't suffer from scrolling issues.

This solution is better because it doesn't hide the scrollbars (jumping affect). It doesn't require event listeners and it's easy to implement. It works in all browsers, although with IE7 & 8 you have to play around (depends on your specific code).

html

<body>
  <div id="YourModal" style="display:none;"></div>
  <div id="Prevent" style="display:none;"></div>
  <div id="WebsiteContainer">
     <div id="Website">
     website goes here...
     </div>
  </div>
</body>

css

body { overflow: hidden; }

#YourModal {
 z-index:200;
 /* modal styles here */
}

#Prevent {
 z-index:100;
 position:absolute;
 left:0px;
 height:100%;
 width:100%;
 background:transparent;
}

#WebsiteContainer {
  z-index:50;
  overflow:auto;
  position: absolute;
  height:100%;
  width:100%;
}
#Website {
  position:relative;
}

jquery/js

function PreventScroll(A) { 
  switch (A) {
    case 'on': $('#Prevent').show(); break;
    case 'off': $('#Prevent').hide(); break;
  }
}

disable/enable the scroll

PreventScroll('on'); // prevent scrolling
PreventScroll('off'); // allow scrolling

wget utility retrieves files from World Wide Web (WWW) using widely used protocols like HTTP, HTTPS and FTP. Wget utility is freely available package and license is under GNU GPL License. This utility can be install any Unix-like Operating system including Windows and MAC OS. It’s a non-interactive command line tool. Main feature of Wget is it’s robustness. It’s designed in such way so that it works in slow or unstable network connections. Wget automatically start download where it was left off in case of network problem. Also downloads file recursively. It’ll keep trying until file has be retrieved completely.

Install wget in linux machine sudo apt-get install wget

Create a folder where you want to download files . sudo mkdir myimages cd myimages

Right click on the webpage and for example if you want image location right click on image and copy image location. If there are multiple images then follow the below:

If there are 20 images to download from web all at once, range starts from 0 to 19.

wget http://joindiaspora.com/img{0..19}.jpg

To format String use

import org.apache.commons.lang.StringUtils;

public class test {

    public static void main(String[] args) {

        String result = StringUtils.leftPad("wrwer", 10, "0");
        System.out.println("The String : " + result);

    }
}

Output : The String : 00000wrwer

Where the first argument is the string to be formatted, Second argument is the length of the desired output length and third argument is the char with which the string is to be padded.

Use the link to download the jar http://commons.apache.org/proper/commons-lang/download_lang.cgi

JDBC uses a so-called "connection URL", so you can escape "+" by "%2B", that is

useTimezone=true&serverTimezone=GMT%2B8

Each tablespace has one or more datafiles that it uses to store data.

The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.

To find out if the actual limit is 32gb, run the following:

select value from v$parameter where name = 'db_block_size';

Compare the result you get with the first column below, and that will indicate what your max datafile size is.

I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).

Block Sz   Max Datafile Sz (Gb)   Max DB Sz (Tb)

--------   --------------------   --------------

   2,048                  8,192          524,264

   4,096                 16,384        1,048,528

   8,192                 32,768        2,097,056

  16,384                 65,536        4,194,112

  32,768                131,072        8,388,224

You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):

select bytes/1024/1024 as mb_size,
       maxbytes/1024/1024 as maxsize_set,
       x.*
from   dba_data_files x

MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).

If your datafile has a low max size or autoextend is not on you could simply run:

alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;

However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:

alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;

I know this is an older post, but I ran into the ERROR! MySQL server PID file could not be found! when trying to start MySQL after making an update to my.cnf file. I did the following to resolve the issue:

1. Deleted my experimental update to my.cnf

2. Deleted the .net.pid and .net.err files.

delete /usr/local/var/mysql/**<YourUserName>**-MBP.airstreamcomm.net.*

3. Ensured all MySQL processes are stopped.

ps -ax | grep mysql
kill **<process id>**

4. Started MySQL server as normal.

mysql.server start

the _T convention is used to indicate the program should use the character set defined for the application (Unicode, ASCII, MBCS, etc.). You can surround your strings with _T( ) to have them stored in the correct format.

 cout << _T( "There are " ) << argc << _T( " arguments:" ) << endl;

No, As others said, "There is no Pointer in PHP." and I add, there is nothing RAM_related in PHP.

And also all answers are clear. But there were points being left out that I could not resist!

There are number of things that acts similar to pointers

• eval construct (my favorite and also dangerous)
• $GLOBALS variable
• Extra '$' sign Before Variables (Like prathk mentioned)
• References

First one

At first I have to say that PHP is really powerful language, knowing there is a construct named "eval", so you can create your PHP code while running it! (really cool!)

although there is the danger of PHP_Injection which is far more destructive that SQL_Injection. Beware!

example:

Code:

$a='echo "Hello World.";';
eval ($a);

Output

Hello World.

So instead of using a pointer to act like another Variable, You Can Make A Variable From Scratch!

Second one

$GLOBAL variable is pretty useful, You can access all variables by using its keys.

example:

Code:

$three="Hello";$variable=" Amazing ";$names="World";
$arr = Array("three","variable","names");
foreach($arr as $VariableName)
    echo $GLOBALS[$VariableName];

Output

Hello Amazing World

Note: Other superglobals can do the same trick in smaller scales.

Third one

You can add as much as '$'s you want before a variable, If you know what you're doing.

example:

Code:

$a="b";
$b="c";
$c="d";
$d="e";
$e="f";

echo $a."-";
echo $$a."-";   //Same as $b
echo $$$a."-";  //Same as $$b or $c
echo $$$$a."-"; //Same as $$$b or $$c or $d
echo $$$$$a;    //Same as $$$$b or $$$c or $$d or $e

Output

b-c-d-e-f

Last one

Reference are so close to pointers, but you may want to check this link for more clarification.

example 1:

Code:

$a="Hello";
$b=&$a;
$b="yello";
echo $a;

Output

yello

example 2:

Code:

function junk(&$tion)
{$GLOBALS['a'] = &$tion;}
$a="-Hello World<br>";
$b="-To You As Well";
echo $a;
junk($b);
echo $a;

Output

-Hello World

-To You As Well

Hope It Helps.

The closest equivalent to Java's toString is to implement __str__ for your class. Put this in your class definition:

def __str__(self):
     return "foo"

You may also want to implement __repr__ to aid in debugging.

See here for more information:

• Special Method Names - Basic Customization

As @jeff-dickey suggested, in the root of your project, make a folder called test. In that folder, make a file called mocha.opts. Now where I try to improve on Jeff's answer, what worked for me was instead of specifying the name of just one test folder, I specified a pattern to find all tests to run in my project by adding this line:

*/tests/*.js --recursive in mocha.opts

If you instead want to specify the exact folders to look for tests in, I did something like this:

shared/tests/*.js --recursive
server/tests/graph/*.js --recursive

I hope this helps anyone who needed more than what the other answers provide

This will definitely work for you...

ArrayList<String> list = new ArrayList<String>();

list.add(textview.getText().toString());
list.add("B");
list.add("C");

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();

    services.AddDbContext<ConfigurationRepository>(options =>
        options.UseSqlServer(Configuration.GetConnectionString("SqlConnectionString")));

    services.AddScoped<IConfigurationBL, ConfigurationBL>();
    services.AddScoped<IConfigurationRepository, ConfigurationRepository>();
}

Blanket.js works perfect too.

npm install --save-dev blanket

in front of your test/tests.js

require('blanket')({
    pattern: function (filename) {
        return !/node_modules/.test(filename);
    }
});

We use IBM Rational Application Developer (RAD) and had the same problem.

ErrorMessage:

Access restriction: The type 'JAXWSProperties' is not API (restriction on required library 'C:\IBM\RAD95\jdk\jre\lib\rt.jar')

Solution:

go to java build path and under Library tab, remove JRE System Library. Then again Add Library --> JRE System Library

After trying and reading carefully, I solved it myself. Solution is to add the following line in build.gradle.

flavorDimensions "versionCode"

android { 
       compileSdkVersion 24
       .....
       flavorDimensions "versionCode"
} 

This is an example of service which I use.

You can get the screen width by subscribing to screenWidth$, or via screenWidth$.value.

The same is for mediaBreakpoint$ ( or mediaBreakpoint$.value)

import {
  Injectable,
  OnDestroy,
} from '@angular/core';
import {
  Subject,
  BehaviorSubject,
  fromEvent,
} from 'rxjs';
import {
  takeUntil,
  debounceTime,
} from 'rxjs/operators';

@Injectable()
export class ResponsiveService implements OnDestroy {
  private _unsubscriber$: Subject<any> = new Subject();
  public screenWidth$: BehaviorSubject<number> = new BehaviorSubject(null);
  public mediaBreakpoint$: BehaviorSubject<string> = new BehaviorSubject(null);

  constructor() {
    this.init();
  }

  init() {
    this._setScreenWidth(window.innerWidth);
    this._setMediaBreakpoint(window.innerWidth);
    fromEvent(window, 'resize')
      .pipe(
        debounceTime(1000),
        takeUntil(this._unsubscriber$)
      ).subscribe((evt: any) => {
        this._setScreenWidth(evt.target.innerWidth);
        this._setMediaBreakpoint(evt.target.innerWidth);
      });
  }

  ngOnDestroy() {
    this._unsubscriber$.next();
    this._unsubscriber$.complete();
  }

  private _setScreenWidth(width: number): void {
    this.screenWidth$.next(width);
  }

  private _setMediaBreakpoint(width: number): void {
    if (width < 576) {
      this.mediaBreakpoint$.next('xs');
    } else if (width >= 576 && width < 768) {
      this.mediaBreakpoint$.next('sm');
    } else if (width >= 768 && width < 992) {
      this.mediaBreakpoint$.next('md');
    } else if (width >= 992 && width < 1200) {
      this.mediaBreakpoint$.next('lg');
    } else if (width >= 1200 && width < 1600) {
      this.mediaBreakpoint$.next('xl');
    } else {
      this.mediaBreakpoint$.next('xxl');
    }
  }

}

Hope this helps someone

You can also use the Termial view to ssh/telnet to your local machine. Doesn't have that funny input box for commands.

Here's a Python 3 version of the functions from @qneill 's answer:

import base64
def encode(key, clear):
    enc = []
    for i in range(len(clear)):
        key_c = key[i % len(key)]
        enc_c = chr((ord(clear[i]) + ord(key_c)) % 256)
        enc.append(enc_c)
    return base64.urlsafe_b64encode("".join(enc).encode()).decode()

def decode(key, enc):
    dec = []
    enc = base64.urlsafe_b64decode(enc).decode()
    for i in range(len(enc)):
        key_c = key[i % len(key)]
        dec_c = chr((256 + ord(enc[i]) - ord(key_c)) % 256)
        dec.append(dec_c)
    return "".join(dec)

The extra encode/decodes are needed because Python 3 has split strings/byte arrays into two different concepts, and updated their APIs to reflect that..

It worked for me, hope you too.

*Note: I have used auto layout in Nib, remember add top and bottom contraints for subviews in contentView

IaaS provides the infrastructure such as virtual machines and other resources like virtual-machine disk image library, block and file-based storage, firewalls, load balancers, IP addresses, virtual local area networks etc. Infrastructure as service or IaaS is the basic layer in cloud computing model.

Common examples: DigitalOcean, Linode, Rackspace, Amazon Web Services (AWS), Cisco Metapod, Microsoft Azure, Google Compute Engine (GCE) are some popular examples of Iaas.

PaaS (Platform as a Service)

PaaS or platform as a service model provides you computing platforms which typically includes an operating system, programming language execution environment, database, web server. technically It is a layer on top of IaaS as the second thing you demand after Infrastructure is a platform.

Common examples: AWS Elastic Beanstalk, Windows Azure, Heroku, Force.com, Google App Engine, Apache Stratos.

SaaS (Software as a Service)

In a SaaS, you are provided access to application services installed at a server. You don’t have to worry about installation, maintenance or coding of that software. You can access and operate the software with just your browser. You don’t have to download or install any kind of setup or OS, the software is just available for you to access and operate. The software maintenance or setup or help will be provided by SaaS provider company and you will only have to pay for your usage.

Common examples: Google Apps, Microsoft office365, Google docs, Gmail, WHMCS billing software

Basic difference between IaaS, PaaS & SaaS

As mentioned above it wont work for primitive types where 0/NO could be a valid value. I am using this code.

NSUserDefaults *defaults= [NSUserDefaults standardUserDefaults];
if([[[defaults dictionaryRepresentation] allKeys] containsObject:@"mykey"]){

    NSLog(@"mykey found");
}

I had a similar problem with a small difference: some a.category_id are not in b and some b.category_id are not in a.
To solve this problem just adapt the excelent answer from beny23 to

select a.col1, b.col2, a.col3, b.col4, a.category_id 
from items_a a
LEFT OUTER JOIN
items_b b 
on a.category_id = b.category_id

Hope this helps someone.
Regards.
