See Should my constructors use "initialization lists" or "assignment"?

Briefly: in your specific case, it does not change anything. But:

• for class/struct members with constructors, it may be more efficient to use option 1.
• only option 1 allows you to initialize reference members.
• only option 1 allows you to initialize const members
• only option 1 allows you to initialize base classes using their constructor
• only option 2 allows you to initialize array or structs that do not have a constructor.

My guess for why option 2 is more common is that option 1 is not well-known, neither are its advantages. Option 2's syntax feels more natural to the new C++ programmer.

you can download USBview and get all the information you need. Along with the list of devices it will also show you the configuration of each device.

For myself this happened in SourceTree when I tried to commit a merge before resolving all of the files. I then marked the last file resolved and yet it still gave me this error when trying to commit. I closed SourceTree and reopened it, and then it committed fine.

You can enable log4j internal logging by defining the 'log4j.debug' variable.

For multiple commits on the wrong branch

If, for you, it is just about 1 commit, then there are plenty of other easier resetting solutions available. For me, I had about 10 commits that I'd accidentally created on master branch instead of, let's call it target, and I did not want to lose the commit history.

What you could do, and what saved me was using this answer as a reference, using a 4 step process, which is -

1. Create a new temporary branch temp from master
2. Merge temp into the branch originally intended for commits, i.e. target
3. Undo commits on master
4. Delete the temporary branch temp.

Here are the above steps in details -

1. Create a new branch from the master (where I had accidentally committed a lot of changes)

   git checkout -b temp
   

   Note: -b flag is used to create a new branch
   Just to verify if we got this right, I'd do a quick git branch to make sure we are on the temp branch and a git log to check if we got the commits right.

2. Merge the temporary branch into the branch originally intended for the commits, i.e. target.
   First, switch to the original branch i.e. target (You might need to git fetch if you haven't)

   git checkout target
   

   Note: Not using -b flag
   Now, let's merge the temporary branch into the branch we have currently checkout out target

   git merge temp
   

   You might have to take care of some conflicts here, if there are. You can push (I would) or move on to the next steps, after successfully merging.

3. Undo the accidental commits on master using this answer as reference, first switch to the master

   git checkout master
   

   then undo it all the way back to match the remote using the command below (or to particular commit, using appropriate command, if you want)

   git reset --hard origin/master
   

   Again, I'd do a git log before and after just to make sure that the intended changes took effect.

4. Erasing the evidence, that is deleting the temporary branch. For this, first you need to checkout the branch that the temp was merged into, i.e. target (If you stay on master and execute the command below, you might get a error: The branch 'temp' is not fully merged), so let's

   git checkout target
   

   and then delete the proof of this mishap

   git branch -d temp
   

There you go.

this is useful to know about hashcode in java :

http://eclipsesource.com/blogs/2012/09/04/the-3-things-you-should-know-about-hashcode/

this datepicker is an excellent solution. datepickers are a must if you want to avoid code injection.

In your CSS:

.carousel-item {
    transition-duration: 1.5s, 1.5s;
}

Take care, the time is included in data-interval defined for the carousel.

Hope it helps... :)

Look into the Dimensions plugin, specifically scrollTop()/scrollLeft(). Information can be found at http://api.jquery.com/scrollTop.

IF you are just trying to have a line in between rows (for example, just above a "Total" row) then there is an easy solution - just add a TableRow with a background color and a specific layout_height such as this:

<TableRow android:layout_height="1px" android:background="#BDBDBD">
   <TextView android:layout_span="2" android:layout_height="1px" 
             android:layout_width="fill_parent" android:text="">
   </TextView>
</TableRow>

Set android:layout_height="1px" or however thick you want the border to be. Fill in as many empty TextView columns as you need to match the rest of your table, or just use one along with android:layout_span as I have demonstrated.

The output will look something like this:

If you are trying to add more complicated borders then the other answers already posted are more appropriate.

Well, local storage speed greatly depends on the browser the client is using, as well as the operating system. Chrome or Safari on a mac could be much faster than Firefox on a PC, especially with newer APIs. As always though, testing is your friend (I could not find any benchmarks).

I really don't see a huge difference in cookie vs local storage. Also, you should be more worried about compatibility issues: not all browsers have even begun to support the new HTML5 APIs, so cookies would be your best bet for speed and compatibility.

You'll need to escape the (escaped) backslash in the first argument as it is a regular expression. Replacement (2nd argument - see Matcher#replaceAll(String)) also has it's special meaning of backslashes, so you'll have to replace those to:

theString.replaceAll("\\\\", "\\\\\\\\");

Just found this link on the MatPlotLib documentation addressing exactly this issue: http://matplotlib.org/faq/howto_faq.html#generate-images-without-having-a-window-appear

They say that the easiest way to prevent the figure from popping up is to use a non-interactive backend (eg. Agg), via matplotib.use(<backend>), eg:

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.savefig('myfig')

I still personally prefer using plt.close( fig ), since then you have the option to hide certain figures (during a loop), but still display figures for post-loop data processing. It is probably slower than choosing a non-interactive backend though - would be interesting if someone tested that.

UPDATE: for Spyder, you usually can't set the backend in this way (Because Spyder usually loads matplotlib early, preventing you from using matplotlib.use()).

Instead, use plt.switch_backend('Agg'), or Turn off "enable support" in the Spyder prefs and run the matplotlib.use('Agg') command yourself.

From these two hints: one, two

If you would like to open link in a new tab, you can:

$("a#thing_to_click").on('click',function(){
    window.open('https://yoururl.com', '_blank');
});

If you only need to test a delay you can use this:

function delay(ms) {
   ms += new Date().getTime();
   while (new Date() < ms){}
}

And then if you want to delay for 2 second you do:

delay(2000);

Might not be the best for production though. More on that in the comments

This is what worked for me in the end.

var showMenu = function(el, menu) {
    //get the position of the placeholder element  
    var pos = $(el).offset();    
    var eWidth = $(el).outerWidth();
    var mWidth = $(menu).outerWidth();
    var left = (pos.left + eWidth - mWidth) + "px";
    var top = 3+pos.top + "px";
    //show the menu directly over the placeholder  
    $(menu).css( { 
        position: 'absolute',
        zIndex: 5000,
        left: left, 
        top: top
    } );

    $(menu).hide().fadeIn();
};

To answer the original question: yes, you can access the index value of a row in apply(). It is available under the key name and requires that you specify axis=1 (because the lambda processes the columns of a row and not the rows of a column).

Working example (pandas 0.23.4):

>>> import pandas as pd
>>> df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
>>> df.set_index('a', inplace=True)
>>> df
   b  c
a      
1  2  3
4  5  6
>>> df['index_x10'] = df.apply(lambda row: 10*row.name, axis=1)
>>> df
   b  c  index_x10
a                 
1  2  3         10
4  5  6         40

Here, i'm creating instance of my class

No, you are not creating the instance of your abstract class here. Rather you are creating an instance of an anonymous subclass of your abstract class. And then you are invoking the method on your abstract class reference pointing to subclass object.

This behaviour is clearly listed in JLS - Section # 15.9.1: -

If the class instance creation expression ends in a class body, then the class being instantiated is an anonymous class. Then:

• If T denotes a class, then an anonymous direct subclass of the class named by T is declared. It is a compile-time error if the class denoted by T is a final class.
• If T denotes an interface, then an anonymous direct subclass of Object that implements the interface named by T is declared.
• In either case, the body of the subclass is the ClassBody given in the class instance creation expression.
• The class being instantiated is the anonymous subclass.

Emphasis mine.

Also, in JLS - Section # 12.5, you can read about the Object Creation Process. I'll quote one statement from that here: -

Whenever a new class instance is created, memory space is allocated for it with room for all the instance variables declared in the class type and all the instance variables declared in each superclass of the class type, including all the instance variables that may be hidden.

Just before a reference to the newly created object is returned as the result, the indicated constructor is processed to initialize the new object using the following procedure:

You can read about the complete procedure on the link I provided.

To practically see that the class being instantiated is an Anonymous SubClass, you just need to compile both your classes. Suppose you put those classes in two different files:

My.java:

abstract class My {
    public void myMethod() {
        System.out.print("Abstract");
    }
}

Poly.java:

class Poly extends My {
    public static void main(String a[]) {
        My m = new My() {};
        m.myMethod();
    }
}

Now, compile both your source files:

javac My.java Poly.java

Now in the directory where you compiled the source code, you will see the following class files:

My.class
Poly$1.class  // Class file corresponding to anonymous subclass
Poly.class

See that class - Poly$1.class. It's the class file created by the compiler corresponding to the anonymous subclass you instantiated using the below code:

new My() {};

So, it's clear that there is a different class being instantiated. It's just that, that class is given a name only after compilation by the compiler.

In general, all the anonymous subclasses in your class will be named in this fashion:

Poly$1.class, Poly$2.class, Poly$3.class, ... so on

Those numbers denote the order in which those anonymous classes appear in the enclosing class.

I changed code in line 1796 file 'bootstrap-datetimepicker.js'. It's worked for me

app._router.stack.forEach(function(r){
  if (r.route && r.route.path){
    console.log(r.route.path)
  }
})

The way I could mitigate the JSON Array to collection of LinkedHashMap objects problem was by using CollectionType rather than a TypeReference . This is what I did and worked:

public <T> List<T> jsonArrayToObjectList(String json, Class<T> tClass) throws IOException {
    ObjectMapper mapper = new ObjectMapper();
    CollectionType listType = mapper.getTypeFactory().constructCollectionType(ArrayList.class, tClass);
    List<T> ts = mapper.readValue(json, listType);
    LOGGER.debug("class name: {}", ts.get(0).getClass().getName());
    return ts;
}

Using the TypeReference, I was still getting an ArrayList of LinkedHashMaps, i.e. does not work:

public <T> List<T> jsonArrayToObjectList(String json, Class<T> tClass) throws IOException {
    ObjectMapper mapper = new ObjectMapper();
    List<T> ts = mapper.readValue(json, new TypeReference<List<T>>(){});
    LOGGER.debug("class name: {}", ts.get(0).getClass().getName());
    return ts;
}

This code:

Option Explicit

Sub ExportMyPicture()

     Dim MyChart As String, MyPicture As String
     Dim PicWidth As Long, PicHeight As Long

     Application.ScreenUpdating = False
     On Error GoTo Finish

     MyPicture = Selection.Name
     With Selection
           PicHeight = .ShapeRange.Height
           PicWidth = .ShapeRange.Width
     End With

     Charts.Add
     ActiveChart.Location Where:=xlLocationAsObject, Name:="Sheet1"
     Selection.Border.LineStyle = 0
     MyChart = Selection.Name & " " & Split(ActiveChart.Name, " ")(2)

     With ActiveSheet
           With .Shapes(MyChart)
                 .Width = PicWidth
                 .Height = PicHeight
           End With

           .Shapes(MyPicture).Copy

           With ActiveChart
                 .ChartArea.Select
                 .Paste
           End With

           .ChartObjects(1).Chart.Export Filename:="MyPic.jpg", FilterName:="jpg"
           .Shapes(MyChart).Cut
     End With

     Application.ScreenUpdating = True
     Exit Sub

Finish:
     MsgBox "You must select a picture"
End Sub

was copied directly from here, and works beautifully for the cases I tested.

Alternative using the pathlib library (often preferred over os.path).

This method avoids iterative use of pandas concat()/apped().

From the pandas documentation:
It is worth noting that concat() (and therefore append()) makes a full copy of the data, and that constantly reusing this function can create a significant performance hit. If you need to use the operation over several datasets, use a list comprehension.

import pandas as pd
from pathlib import Path

dir = Path("../relevant_directory")

df = (pd.read_csv(f) for f in dir.glob("*.csv"))
df = pd.concat(df)

The above final .htaccess and Test A,B,C,D,E did not work for me. I just used below 2 lines code and it works in my WordPress website:

RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://www.thehotskills.com/$1 [R=301,L]

I'm not sure where I was making the mistake but this page helped me out.

Here's a solution that mixes the code by Jared Rummler and AndroidMechanic.

Note: fb://facewebmodal/f?href= redirects to a weird facebook page that doesn't have the like and other important buttons, which is why I try fb://page/. It works fine with the current Facebook version (126.0.0.21.77, June 1st 2017). The catch might be useless, I left it just in case.

public static String getFacebookPageURL(Context context)
{
    final String FACEBOOK_PAGE_ID = "123456789";
    final String FACEBOOK_URL = "MyFacebookPage";

    if(appInstalledOrNot(context, "com.facebook.katana"))
    {
        try
        {
            return "fb://page/" + FACEBOOK_PAGE_ID;
            // previous version, maybe relevant for old android APIs ?
            // return "fb://facewebmodal/f?href=" + FACEBOOK_URL;
        }
        catch(Exception e) {}
    }
    else
    {
        return FACEBOOK_URL;
    }

}

Here's the appInstalledOrNot function which I took (and modified) from Aerrow's answer to this post

private static boolean appInstalledOrNot(Context context, String uri)
{
    PackageManager pm = context.getPackageManager();
    try
    {
        pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
        return true;
    }
    catch(PackageManager.NameNotFoundException e)
    {
    }

    return false;
}

How to get the Facebook ID of a page:

1. Go to your page
2. Right-click and View Page Source
3. Find in page: fb://page/?id=
4. Here you go!

In my case, the view was not viewed in xib. in xib the View was size = none (4th tab right hand). I set size to Freeform and reload xCode. view was appealed and I set the proper link to View.

Even more useful, if you have multiple parameters you can access any/all of them with:

_mock.Setup(x => x.DoSomething(It.IsAny<string>(),It.IsAny<string>(),It.IsAny<string>())
     .Returns((string a, string b, string c) => string.Concat(a,b,c));

You always need to reference all the arguments, to match the method's signature, even if you're only going to use one of them.

Boolean is the object wrapper class for the primitive boolean. This class, as any class, can indeed be null. For performance and memory reasons it is always best to use the primitive.

The wrapper classes in the Java API serve two primary purposes:

1. To provide a mechanism to “wrap” primitive values in an object so that the primitives can be included in activities reserved for objects, like as being added to Collections, or returned from a method with an object return value.
2. To provide an assortment of utility functions for primitives. Most of these functions are related to various conversions: converting primitives to and from String objects, and converting primitives and String objects to and from different bases (or radix), such as binary, octal, and hexadecimal.

http://en.wikipedia.org/wiki/Primitive_wrapper_class

i know i know even though its not allowed and so on, sometime u actualy need it so for the those:

class a {}
class b : a {}
class c : b {}

like in my case i wanted to do this class b : Form (yep the windows.forms) class c : b {}

cause half of the function were identical and with interface u must rewrite them all

File outputfile = new File("image.jpg");
ImageIO.write(bufferedImage, "jpg", outputfile);

String str = new String("SOME")

always create a new object on the heap

String str="SOME" 

uses the String pool

Try this small example:

        String s1 = new String("hello");
        String s2 = "hello";
        String s3 = "hello";

        System.err.println(s1 == s2);
        System.err.println(s2 == s3);

To avoid creating unnecesary objects on the heap use the second form.

Submit a form that contains an input with value of canvas toDataURL('image/png') e.g

//JAVASCRIPT

    var canvas = document.getElementById("canvas");
    var url = canvas.toDataUrl('image/png');

Insert the value of the url to your hidden input on form element.

//PHP

    $data = $_POST['photo'];
    $data = str_replace('data:image/png;base64,', '', $data);
    $data = base64_decode($data);
    file_put_contents("i".  rand(0, 50).".png", $data);

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

I realize this was long ago answered but want to suggest an additional approach that avoids the nested try-with-resources double block.

public List<User> getUser(int userId) {
    try (Connection con = DriverManager.getConnection(myConnectionURL);
         PreparedStatement ps = createPreparedStatement(con, userId); 
         ResultSet rs = ps.executeQuery()) {

         // process the resultset here, all resources will be cleaned up

    } catch (SQLException e) {
        e.printStackTrace();
    }
}

private PreparedStatement createPreparedStatement(Connection con, int userId) throws SQLException {
    String sql = "SELECT id, username FROM users WHERE id = ?";
    PreparedStatement ps = con.prepareStatement(sql);
    ps.setInt(1, userId);
    return ps;
}

IF d was created by Newtonsoft you can use this to read property names and values:

    foreach (JProperty property in d)
    {
        DoSomething(property.Name, property.Value);
    }

As part of htmlAttributes,e.g.

Html.BeginForm(
    action, controller, FormMethod.Post, new { enctype="multipart/form-data"})

Or you can pass null for action and controller to get the same default target as for BeginForm() without any parameters:

Html.BeginForm(
    null, null, FormMethod.Post, new { enctype="multipart/form-data"})

why don't you give LiteralControl a try?

 myLitCtrl.Text="<h2><p>Notify:</p> Alert</h2>";

A CLASSPATH entry is either a directory at the head of a package hierarchy of .class files, or a .jar file. If you're expecting ./lib to include all the .jar files in that directory, it won't. You have to name them explicitly.

In Python you can iterate over the list itself:

for item in my_list:
   #do something with item

or to use indices you can use xrange():

for i in xrange(1,len(my_list)):    #as indexes start at zero so you 
                                    #may have to use xrange(len(my_list))
    #do something here my_list[i]

There's another built-in function called enumerate(), which returns both item and index:

for index,item in enumerate(my_list):
    # do something here

examples:

In [117]: my_lis=list('foobar')

In [118]: my_lis
Out[118]: ['f', 'o', 'o', 'b', 'a', 'r']

In [119]: for item in my_lis:
    print item
   .....:     
f
o
o
b
a
r

In [120]: for i in xrange(len(my_lis)):
    print my_lis[i]
   .....:     
f
o
o
b
a
r

In [122]: for index,item in enumerate(my_lis):
    print index,'-->',item
   .....:     
0 --> f
1 --> o
2 --> o
3 --> b
4 --> a
5 --> r

From the notebook menu you can save the file directly as a python script. Go to the 'File' option of the menu, then select 'Download as' and there you would see a 'Python (.py)' option.

Another option would be to use nbconvert from the command line:

jupyter nbconvert --to script 'my-notebook.ipynb'

Have a look here.

After installing git-extentions (http://gitextensions.github.io/) you can run .sh file from the command prompt. (No ./script.sh required, just run it like a bat/cmd file) Or you can run them in a "full" bash environment by using the MinGW Git bash shell.

I am not a great fan of Cygwin (yes I am sure it's really powerful), so running bash scripts on windows without having to install it perfect for me.

function getEffectiveVotes($id) 

According to the function header, there is only one parameter variable ($id). Thus, on line 27, the votes[] array is undefined and out of scope. You need to add another parameter value to the function header so that function getEffectiveVotes() knows to expect two parameters. I'm rusty, but something like this would work.

function getEffectiveVotes($id, $votes)

I'm not saying this is how it should be done, but you might want to research how PHP passes its arrays and decide if you need to explicitly state to pass it by reference

function getEffectiveVotes($id &$votes)    <---I forget, no time to look it up right now.

Lastly, call function getEffectiveVotes() with both arguments wherever it is supposed to be called.

You were looking for help on installations with pip. You can find it with the following command:

pip install --help

Running pip install -e /path/to/package installs the package in a way, that you can edit the package, and when a new import call looks for it, it will import the edited package code. This can be very useful for package development.

From http://htmlexplorer.com/2015/01/assign-output-var_dump-print_r-php-variable.html:

var_dump and print_r functions can only output directly to browser. So the output of these functions can only retrieved by using output control functions of php. Below method may be useful to save the output.

function assignVarDumpValueToString($object) {
    ob_start();
    var_dump($object);
    $result = ob_get_clean();
    return $result;
}

ob_get_clean() can only clear last data entered to internal buffer. So ob_get_contents method will be useful if you have multiple entries.

From the same source as above:

function varDumpToErrorLog( $var=null ){
    ob_start();                    // start reading the internal buffer
    var_dump( $var);          
    $grabbed_information = ob_get_contents(); // assigning the internal buffer contents to variable
    ob_end_clean();                // clearing the internal buffer.
    error_log( $grabbed_information);        // saving the information to error_log
}

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

no need to do a replacement. the regex will give you what u wanted directly:

"(?<=_)[^_]*\.jpg"

tested with grep:

 echo "3.04_somename.jpg"|grep -oP "(?<=_)[^_]*\.jpg"
somename.jpg

Just in case someone has the same pb. :

I couldn't unmount the mount point (here /mnt) of a chroot jail.

Here are the commands I typed to investigate :

$ umount /mnt
umount: /mnt: target is busy.
$ df -h | grep /mnt
/dev/mapper/VGTout-rootFS  4.8G  976M  3.6G  22% /mnt
$ fuser -vm /mnt/
                     USER        PID ACCESS COMMAND
/mnt:                root     kernel mount /mnt
$ lsof +f -- /dev/mapper/VGTout-rootFS
$

As you can notice, even lsof returns nothing.

Then I had the idea to type this :

$ df -ah | grep /mnt
/dev/mapper/VGTout-rootFS  4.8G  976M  3.6G  22% /mnt
dev                        2.9G     0  2.9G   0% /mnt/dev
$ umount /mnt/dev
$ umount /mnt
$ df -ah | grep /mnt
$

Here it was a /mnt/dev bind to /dev that I had created to be able to repair my system inside from the chroot jail.

After umounting it, my pb. is now solved.

The Matlab Compiler is the standard way to do this. mcc is the command. The Matlab Runtime is required to run the programs; I'm not sure if it can be directly integrated with the executable or not.

Suspend the process with CTRL+Z then use the command bg to resume it in background. For example:

sleep 60
^Z  #Suspend character shown after hitting CTRL+Z
[1]+  Stopped  sleep 60  #Message showing stopped process info
bg  #Resume current job (last job stopped)

More about job control and bg usage in bash manual page:

JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.

bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.

EDIT

To start a process where you can even kill the terminal and it still carries on running

nohup [command] [-args] > [filename] 2>&1 &

e.g.

nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &

To just ignore the output (not very wise) change the filename to /dev/null

To get the error message set to a different file change the &1 to a filename.

In addition: You can use the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process.

What is the difference between exit(0) and exit(1) in C language?

exit(0) indicates successful program termination & it is fully portable, While
exit(1) (usually) indicates unsucessful termination. However, it's usage is non-portable.

Note that the C standard defines EXIT_SUCCESS and EXIT_FAILURE to return termination status from a C program.

0 and EXIT_SUCCESS are the values specified by the standard to indicate successful termination, however, only EXIT_FAILURE is the standard value for returning unsucessful termination. 1 is used for the same in many implementations though.

Reference:

C99 Standard: 7.20.4.3 The exit function
Para 5

Finally, control is returned to the host environment. If the value of status is zero or EXIT_SUCCESS, an implementation-de?ned form of the status successful termination is returned. If the value of status is EXIT_FAILURE , an implementation-de?ned form of the status unsuccessful termination is returned. Otherwise the status returned is implementation-de?ned.

How's this for a work around (using an actual table)?

table {
    border-collapse: collapse;
}

tr.row {
    border-bottom: solid white 30px; /* change "white" to your background color */
}

It's not as dynamic, since you have to explicitly set the color of the border (unless there's a way around that too), but this is something I'm experimenting with on a project of my own.

Edit to include comments regarding transparent:

tr.row {
    border-bottom: 30px solid transparent;
}

I had a ton of trouble with this and then found a great solution:

Create a file in a text editor called whoami.php with the below code as it's content, save the file and upload it to public_html (or whatever you root of your webserver directory is named). It should output a useful string that you can use to track down the user the webserver is running as, my output was "php is running as user: nt authority\iusr" which allowed me to track down the permissions I needed to modify to the user "IUSR".

<?php
  // outputs the username that owns the running php/httpd process
  // (on a system with the "whoami" executable in the path)
  echo 'php is running as user: ' . exec('whoami');
?>

To be efficient, and random, it might be best to have two different queries.

Something like...

SELECT table_id FROM table

Then, in your chosen language, pick a random id, then pull that row's data.

SELECT * FROM table WHERE table_id = $rand_id

But that's not really a good idea if you're expecting to have lots of rows in the table. It would be better if you put some kind of limit on what you randomly select from. For publications, maybe randomly pick from only items posted within the last year.

nums = str(tuple([1,2,3]))
mul_nums = nums.replace(',','*')
print(eval(mul_nums))

Change encoding in notepad++ UTF-8 with BOM. That is how it worked for me

To override this and fix the issue on your local machine you can do the following changes within your php.ini configuration file.

1. To locate your php.ini configuration file you can use the following command: php --ini

After running this command you should see an output like the following:

Configuration File (php.ini) Path: /usr/local/etc/php/7.3
Loaded Configuration File:         /usr/local/etc/php/7.3/php.ini <---- note the path
Scan for additional .ini files in: /usr/local/etc/php/7.3/conf.d
Additional .ini files parsed:      /usr/local/etc/php/7.3/conf.d/ext-opcache.ini

The file we want to change is the Loaded Configuration.

2. Open and search for the memory_limit you can set the memory_limit = -1 to give an unlimited amount of memory to PHP processes or you can set 512MB, 1G, 2G, 5G,....

   $ nano /usr/local/etc/php/7.3/php.ini

locate and set:

$ memory_limit = -1 or memory_limit = 1G

3. After saving your file, you can verify the PHP changes by running this command which will output the current memory settings in your php.ini file:

   php -r "echo ini_get('memory_limit').PHP_EOL;"

NOTE: After saving, the new memory will be working. You don't need to do anything else.

There are two ways to sum of a column

dataset = pd.read_csv("data.csv")

1: sum(dataset.Column_name)

2: dataset['Column_Name'].sum()

If there is any issue in this the please correct me..

Although there are a lot of good tips here I'd like to answer the question you asked:

So in other words can they work hand in hand just like Apache/Perl or Apache/PHP etc..

YES, you can run Node.js on Apache along side Perl and PHP IF you run it as a CGI module. As of yet, I am unable to find a mod-node for Apache but check out: CGI-Node for Apache here http://www.cgi-node.org/ .

The interesting part about cgi-node is that it uses JavaScript exactly like you would use PHP to generate dynamic content, service up static pages, access SQL database etc. You can even share core JavaScript libraries between the server and the client/browser.

I think the shift to a single language between client and server is happening and JavaScript seems to be a good candidate.

A quick example from cgi-node.org site:

<? include('myJavaScriptFile.js'); ?>
<html>
   <body>
      <? var helloWorld = 'Hello World!'; ?>
      <b><?= helloWorld ?><br/>
      <? for( var index = 0; index < 10; index++) write(index + ' '); ?>
   </body>
</html>

This outputs:

Hello World!
0 1 2 3 4 5 6 7 8 9

You also have full access to the HTTP request. That includes forms, uploaded files, headers etc.

I am currently running Node.js through the cgi-node module on Godaddy.

CGI-Node.org site has all the documentation to get started.

I know I'm raving about this but it is finally a relief to use something other than PHP. Also, to be able to code JavaScript on both client and server.

Hope this helps.

It seems to me that the answer to this question is (at least now) clearly documented on the Safari HTML5 docs:

User Control of Downloads Over Cellular Networks

In Safari on iOS (for all devices, including iPad), where the user may be on a cellular network and be charged per data unit, preload and autoplay are disabled. No data is loaded until the user initiates it. This means the JavaScript play() and load() methods are also inactive until the user initiates playback, unless the play() or load() method is triggered by user action. In other words, a user-initiated Play button works, but an onLoad="play()" event does not.

This plays the movie: <input type="button" value="Play" onClick="document.myMovie.play()">

This does nothing on iOS: <body onLoad="document.myMovie.play()">

Thanks jbaliuka for the suggestion. I opened the registry editor (by typing regedit in cmd) and going to HKEY_CLASSES_ROOT > jarfile > shell > open > command, then opening (Default) and changing the value from

"C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*

to

"C:\Program Files\Java\jre7\bin\java.exe" -jar "%1" %*

(I just removed the w in javaw.exe.) After that you have to right click a jar -> open with -> choose default program -> navigate to your java folder and open \jre7\bin\java.exe (or any other java.exe file in you java folder). If it doesn't work, try switching to javaw.exe, open a jar file with it, then switch back.

I don't know anything about editing the registry except that it's dangerous, so you might wanna back it up before doing this (in the top bar, File>Export).

use the request() helper instead. You don't have to worry about use statements and thus this sort of problem wont happen again.

$input = request()->all();

simple

The code of exchange is below:

public <T> ResponseEntity<T> exchange(String url, HttpMethod method,
            HttpEntity<?> requestEntity, Class<T> responseType, Object... uriVariables) throws RestClientException

Exception RestClientException has HttpClientErrorException and HttpStatusCodeException exception.

So in RestTemplete there may occure HttpClientErrorException and HttpStatusCodeException exception. In exception object you can get exact error message using this way: exception.getResponseBodyAsString()

Here is the example code:

public Object callToRestService(HttpMethod httpMethod, String url, Object requestObject, Class<?> responseObject) {

        printLog( "Url : " + url);
        printLog( "callToRestService Request : " + new GsonBuilder().setPrettyPrinting().create().toJson(requestObject));

        try {

            RestTemplate restTemplate = new RestTemplate();
            restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
            restTemplate.getMessageConverters().add(new StringHttpMessageConverter());


            HttpHeaders requestHeaders = new HttpHeaders();
            requestHeaders.setContentType(MediaType.APPLICATION_JSON);

            HttpEntity<Object> entity = new HttpEntity<>(requestObject, requestHeaders);

            long start = System.currentTimeMillis();

            ResponseEntity<?> responseEntity = restTemplate.exchange(url, httpMethod, entity, responseObject);

            printLog( "callToRestService Status : " + responseEntity.getStatusCodeValue());


            printLog( "callToRestService Body : " + new GsonBuilder().setPrettyPrinting().create().toJson(responseEntity.getBody()));

            long elapsedTime = System.currentTimeMillis() - start;
            printLog( "callToRestService Execution time: " + elapsedTime + " Milliseconds)");

            if (responseEntity.getStatusCodeValue() == 200 && responseEntity.getBody() != null) {
                return responseEntity.getBody();
            }

        } catch (HttpClientErrorException exception) {
            printLog( "callToRestService Error :" + exception.getResponseBodyAsString());
            //Handle exception here
        }catch (HttpStatusCodeException exception) {
            printLog( "callToRestService Error :" + exception.getResponseBodyAsString());
            //Handle exception here
        }
        return null;
    }

Here is the code description:

In this method you have to pass request and response class. This method will automatically parse response as requested object.

First of All you have to add message converter.

restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
            restTemplate.getMessageConverters().add(new StringHttpMessageConverter());

Then you have to add requestHeader. Here is the code:

HttpHeaders requestHeaders = new HttpHeaders();
            requestHeaders.setContentType(MediaType.APPLICATION_JSON);

            HttpEntity<Object> entity = new HttpEntity<>(requestObject, requestHeaders);

Finally, you have to call exchange method:

ResponseEntity<?> responseEntity = restTemplate.exchange(url, httpMethod, entity, responseObject);

For prety printing i used Gson library. here is the gradle : compile 'com.google.code.gson:gson:2.4'

You can just call the bellow code to get response:

ResponseObject response=new RestExample().callToRestService(HttpMethod.POST,"URL_HERE",new RequestObject(),ResponseObject.class);

Here is the full working code:

import com.google.gson.GsonBuilder;
import org.springframework.http.*;
import org.springframework.http.converter.StringHttpMessageConverter;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.client.HttpClientErrorException;
import org.springframework.web.client.HttpStatusCodeException;
import org.springframework.web.client.RestTemplate;


public class RestExample {

    public RestExample() {

    }

    public Object callToRestService(HttpMethod httpMethod, String url, Object requestObject, Class<?> responseObject) {

        printLog( "Url : " + url);
        printLog( "callToRestService Request : " + new GsonBuilder().setPrettyPrinting().create().toJson(requestObject));

        try {

            RestTemplate restTemplate = new RestTemplate();
            restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
            restTemplate.getMessageConverters().add(new StringHttpMessageConverter());


            HttpHeaders requestHeaders = new HttpHeaders();
            requestHeaders.setContentType(MediaType.APPLICATION_JSON);

            HttpEntity<Object> entity = new HttpEntity<>(requestObject, requestHeaders);

            long start = System.currentTimeMillis();

            ResponseEntity<?> responseEntity = restTemplate.exchange(url, httpMethod, entity, responseObject);

            printLog( "callToRestService Status : " + responseEntity.getStatusCodeValue());


            printLog( "callToRestService Body : " + new GsonBuilder().setPrettyPrinting().create().toJson(responseEntity.getBody()));

            long elapsedTime = System.currentTimeMillis() - start;
            printLog( "callToRestService Execution time: " + elapsedTime + " Milliseconds)");

            if (responseEntity.getStatusCodeValue() == 200 && responseEntity.getBody() != null) {
                return responseEntity.getBody();
            }

        } catch (HttpClientErrorException exception) {
            printLog( "callToRestService Error :" + exception.getResponseBodyAsString());
            //Handle exception here
        }catch (HttpStatusCodeException exception) {
            printLog( "callToRestService Error :" + exception.getResponseBodyAsString());
            //Handle exception here
        }
        return null;
    }

    private void printLog(String message){
        System.out.println(message);
    }
}

Thanks :)

 NSTimer.scheduledTimerWithTimeInterval(NSTimeInterval(3), target: self, selector: "functionHere", userInfo: nil, repeats: false)

This would call the function functionHere() with a 3 seconds delay

An output stream is generally related to some data destination like a file or a network etc.In java output stream is a destination where data is eventually written and it ends

import java.io.printstream;

class PPrint {
    static PPrintStream oout = new PPrintStream();
}

class PPrintStream {
    void print(String str) { 
        System.out.println(str)
    }
}

class outputstreamDemo {
    public static void main(String args[]) {
        System.out.println("hello world");
        System.out.prinln("this is output stream demo");
    }
}

Note that reversing the whole string (either with the rbegin()/rend() range constructor or with std::reverse) and comparing it with the input would perform unnecessary work.

It's sufficient to compare the first half of the string with the latter half, in reverse:

#include <string>
#include <algorithm>
#include <iostream>
int main()
{
    std::string s;
    std::cin >> s;
    if( equal(s.begin(), s.begin() + s.size()/2, s.rbegin()) )
        std::cout << "is a palindrome.\n";
    else
        std::cout << "is NOT a palindrome.\n";
}

The values indicated by Ram Sharma might need to be changed in Wamp alias configuration files instead.

When you want to use a transcompiler, then you could give TypeScript a try. It supports draft ECMA features (in the proposal, interfaces are called "protocols") similar to what languages like coffeescript or babel do.

In TypeScript your interface can look like:

interface IMyInterface {
    id: number; // TypeScript types are lowercase
    name: string;
    callback: (key: string; value: any; array: string[]) => void;
    type: "test" | "notATest"; // so called "union type"
}

What you can't do:

• Define RegExp patterns for type value
• Define validation like string length
• Number ranges
• etc.

This is because, in C#, single quotes ('') denote (or encapsulate) a single character, whereas double quotes ("") are used for a string of characters. For example:

var myChar = '=';

var myString = "==";

If the submodule was accidentally added because you added, committed and pushed a folder that was already a Git repository (contained .git), you won’t have a .gitmodules file to edit, or anything in .git/config. In this case all you need is :

git rm --cached subfolder
git add subfolder
git commit -m "Enter message here"
git push

FWIW, I also removed the .git folder before doing the git add.

Set the colspan attribute to 2.

...but please don't use tables for layout.

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

Google is returning a very useful error message, which helps to correct the issue!

HandlerThread is better option to normal java Threads in Android .

1. Create a HandlerThread and start it
2. Create a Handler with Looper from HandlerThread :requestHandler
3. post a Runnable task on requestHandler

Communication with UI Thread from HandlerThread

1. Create a Handler with Looper for main thread : responseHandler and override handleMessage method
2. Inside Runnable task of other Thread ( HandlerThread in this case), call sendMessage on responseHandler
3. This sendMessage result invocation of handleMessage in responseHandler.
4. Get attributes from the Message and process it, update UI

Example: Update TextView with data received from a web service. Since web service should be invoked on non-UI thread, created HandlerThread for Network Operation. Once you get the content from the web service, send message to your main thread (UI Thread) handler and that Handler will handle the message and update UI.

Sample code:

HandlerThread handlerThread = new HandlerThread("NetworkOperation");
handlerThread.start();
Handler requestHandler = new Handler(handlerThread.getLooper());

final Handler responseHandler = new Handler(Looper.getMainLooper()) {
    @Override
    public void handleMessage(Message msg) {
        txtView.setText((String) msg.obj);
    }

I'm not sure how helpful this answer is for your current application, but it may prove helpful for the next applications that you will be developing.

As iOS does not use Java like Android, your options are quite limited:

1) if your application is written mostly in C/C++ using JNI, you can write a wrapper and interface it with the iOS (i.e. provide callbacks from iOS to your JNI written function). There may be frameworks out there that help you do this easier, but there's still the problem of integrating the application and adapting it to the framework (and of course the fact that the application has to be written in C/C++).

2) rewrite it for iOS. I don't know whether there are any good companies that do this for you. Also, due to the variety of applications that can be written which can use different services and API, there may not be any software that can port it for you (I guess this kind of software is like a gold mine heh) or do a very good job at that.

3) I think that there are Java->C/C++ converters, but there won't help you at all when it comes to API differences. Also, you may find yourself struggling more to get the converted code working on any of the platforms rather than rewriting your application from scratch for iOS.

The problem depends quite a bit on the services and APIs your application is using. I haven't really look this up, but there may be some APIs that provide certain functionality in Android that iOS doesn't provide.

Using C/C++ and natively compiling it for the desired platform looks like the way to go for Android-iOS-Win7Mobile cross-platform development. This gets you somewhat of an application core/kernel which you can use to do the actual application logic.

As for the OS specific parts (APIs) that your application is using, you'll have to set up communication interfaces between them and your application's core.

Since JSF 2.3 all the bean scopes defined in package javax.faces.bean package have been deprecated to align the scopes with CDI. Moreover they're only applicable if your bean is using @ManagedBean annotation. If you are using JSF versions below 2.3 refer to the legacy answer at the end.

From JSF 2.3 here are scopes that can be used on JSF Backing Beans:

1. @javax.enterprise.context.ApplicationScoped: The application scope persists for the entire duration of the web application. That scope is shared among all requests and all sessions. This is useful when you have data for whole application.

2. @javax.enterprise.context.SessionScoped: The session scope persists from the time that a session is established until session termination. The session context is shared between all requests that occur in the same HTTP session. This is useful when you wont to save data for a specific client for a particular session.

3. @javax.enterprise.context.ConversationScoped: The conversation scope persists as log as the bean lives. The scope provides 2 methods: Conversation.begin() and Conversation.end(). These methods should called explicitly, either to start or end the life of a bean.

4. @javax.enterprise.context.RequestScoped: The request scope is short-lived. It starts when an HTTP request is submitted and ends after the response is sent back to the client. If you place a managed bean into request scope, a new instance is created with each request. It is worth considering request scope if you are concerned about the cost of session scope storage.

5. @javax.faces.flow.FlowScoped: The Flow scope persists as long as the Flow lives. A flow may be defined as a contained set of pages (or views) that define a unit of work. Flow scoped been is active as long as user navigates with in the Flow.

6. @javax.faces.view.ViewScoped: A bean in view scope persists while the same JSF page is redisplayed. As soon as the user navigates to a different page, the bean goes out of scope.

The following legacy answer applies JSF version before 2.3

As of JSF 2.x there are 4 Bean Scopes:

• @SessionScoped
• @RequestScoped
• @ApplicationScoped
• @ViewScoped

Session Scope: The session scope persists from the time that a session is established until session termination. A session terminates if the web application invokes the invalidate method on the HttpSession object, or if it times out.

RequestScope: The request scope is short-lived. It starts when an HTTP request is submitted and ends after the response is sent back to the client. If you place a managed bean into request scope, a new instance is created with each request. It is worth considering request scope if you are concerned about the cost of session scope storage.

ApplicationScope: The application scope persists for the entire duration of the web application. That scope is shared among all requests and all sessions. You place managed beans into the application scope if a single bean should be shared among all instances of a web application. The bean is constructed when it is first requested by any user of the application, and it stays alive until the web application is removed from the application server.

ViewScope: View scope was added in JSF 2.0. A bean in view scope persists while the same JSF page is redisplayed. (The JSF specification uses the term view for a JSF page.) As soon as the user navigates to a different page, the bean goes out of scope.

Choose the scope you based on your requirement.

It moves table down because there is no much space, try to decrease/increase width of certain elements so that it finds some space and does not push the table down. Also you may want to use absolute positioning to position the div at exactly the place you want, for example:

<style>
 #div_id
 {
   position:absolute;
   top:100px; /* set top value */
   left:100px; /* set left value */
   width:100px;  /* set width value */
 }
</style>

If you want to appear it over something, you also need to give it z-index, so it might look like this:

<style>
 #div_id
 {
   position:absolute;
   z-index:999;
   top:100px; /* set top value */
   left:100px; /* set left value */
   width:100px;  /* set width value */
 }
</style>

Following are the rules defining the valid combinations in each number of an IP address:

• Any one- or two-digit number.

• Any three-digit number beginning with 1.

• Any three-digit number beginning with 2 if the second digit is 0 through 4.

• Any three-digit number beginning with 25 if the third digit is 0 through 5.

Let'start with (((25[0-5])|(2[0-4]\d)|(1\d{2})|(\d{1,2}))\.), a set of four nested subexpressions, and we’ll look at them in reverse order. (\d{1,2}) matches any one- or two-digit number or numbers 0 through 99. (1\d{2}) matches any three-digit number starting with 1 (1 followed by any two digits), or numbers 100 through 199. (2[0-4]\d) matches numbers 200 through 249. (25[0-5]) matches numbers 250 through 255. Each of these subexpressions is enclosed within another subexpression with an | between each (so that one of the four subexpressions has to match, not all). After the range of numbers comes \. to match ., and then the entire series (all the number options plus \.) is enclosed into yet another subexpression and repeated three times using {3}. Finally, the range of numbers is repeated (this time without the trailing \.) to match the final IP address number. By restricting each of the four numbers to values between 0 and 255, this pattern can indeed match valid IP addresses and reject invalid addresses.

Excerpt From: Ben Forta. “Learning Regular Expressions.”

If neither a character is wanted at the beginning of IP address nor at the end, ^ and $ metacharacters ought to be used, respectively.

^(((25[0-5])|(2[0-4]\d)|(1\d{2})|(\d{1,2}))\.){3}(((25[0-5])|(2[0-4]\d)|(1\d{2})|(\d{1,2})))$

You can connect to a AWS ec-2 instance using the following commands.

chmod 400 mykey.pem

ssh -i mykey.pem username@your-ip

by default the machine name usually be like ubuntu since usually ubuntu machine is used as a server so the following command will work in that case.

ssh -i mykey.pem ubuntu@your-ip

A little late this comment but I will leave here my results working with the library of SharePoin Online and it is very easy to use and implement in your project, just go to the NuGet administrator of .Net and Add Microsoft.SharePoint.CSOM to your project .

        public string DownloadFiles()

                System.IO.DirectoryInfo di = new DirectoryInfo(tempLocation);
                foreach (FileInfo file in di.GetFiles())
                {

                if (clientContext.HasPendingRequest)
                    clientContext.ExecuteQuery();

                foreach (ClientOM.File file in files)

            }
        }

    }
}

Then to invoke the functions from the controller in this case MVC ASP.NET is done in the following way.

using MvcApplication.Models.Home;
using System;
using System.Web.Mvc;

namespace MvcApplication.Controllers
{
    public class SharepointController : MvcBoostraBaseController
    {
        [HttpPost]
        public ActionResult Upload(FormCollection form)
        {
            try
            {
                SharepointModel sharepointModel = new SharepointModel();
                return Json(sharepointModel.UploadMultiFiles(Request, Server), JsonRequestBehavior.AllowGet);
            }
            catch (Exception ex)
            {
                return ThrowJSONError(ex);
            }
        }

        public ActionResult Download(string ServerUrl, string RelativeUrl)
        {
            try
            {
                SharepointModel sharepointModel = new SharepointModel();
                return Json(sharepointModel.DownloadFiles(), JsonRequestBehavior.AllowGet);
            }
            catch (Exception ex)
            {
                return ThrowJSONError(ex);
            }
        }
    }
}

All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if to bind them all together in the way I believe you intend.

For those of you who have tried all the above mentioned methods including Windows system env. variables, .bashrc, .bashprofile, etc. AND can see the correct path in 'echo $PATH' ... I may have a solution for you.

suppress the errors using exec 2> /dev/null

My script runs fine but was throwing 'command not found' or 'No directory found' errors even though, as far as I can tell, the paths were flush. So, if you suppress those errors (might have to also add 'set +e'), than it works properly.

Giving such permission can be dangerous, especially if your web application uses that same username.

Now the web user (and the whole world wide web) also has the permission to create and drop objects within your database. Think SQL Injection!

I recommend granting Execute privileges only to the specific user on the given object as follows:

grant execute on storedProcedureNameNoquotes to myusernameNoquotes

Now the user myusernameNoquotes can execute procedure storedProcedureNameNoquotes without other unnecessary permissions to your valuable data.

One way to do this if dealing with sorted range index is:

data = data.sort_index(ascending=False)

This approach has the benefits of (1) being a single line, (2) not requiring a utility function, and most importantly (3) not actually changing any of the data in the dataframe.

Caveat: this works by sorting the index in descending order and so may not always be appropriate or generalize for any given Dataframe.

Just use good old HTML:

<input type="button" value="Submit" />

Wrap it as the subject of a link, if you so desire:

<a href="http://somewhere.com"><input type="button" value="Submit" /></a>

Or if you decide you want javascript to provide some other functionality:

<input type="button" value="Cancel" onclick="javascript: someFunctionThatCouldIncludeRedirect();"/>

The specificity is calculated based on the amount of id, class and tag selectors in your rule. Id has the highest specificity, then class, then tag. Your first rule is now more specific than the second one, since they both have a class selector, but the first one also has two tag selectors.

To make the second one override the first one, you can make more specific by adding information of it's parents:

table.rule1 tr td.rule2 {
    background-color: #ffff00;
}

Here is a nice article for more information on selector precedence.

I looked at Nate Barr's answer above, which you seemed to like. It doesn't seem very different from the simpler

html {background-color: grey}

You need to run this in the command line.

SET PATH=C:\Program Files\Nodejs;%PATH%

Add this function to your root App component and then run it from your constructor after adding your font using these instructions. https://medium.com/react-native-training/react-native-custom-fonts-ccc9aacf9e5e

import {Text, TextInput} from 'react-native'

SetDefaultFontFamily = () => {
    let components = [Text, TextInput]

    const customProps = {
        style: {
            fontFamily: "Rubik"
        }
    }

    for(let i = 0; i < components.length; i++) {
        const TextRender = components[i].prototype.render;
        const initialDefaultProps = components[i].prototype.constructor.defaultProps;
        components[i].prototype.constructor.defaultProps = {
            ...initialDefaultProps,
            ...customProps,
        }
        components[i].prototype.render = function render() {
            let oldProps = this.props;
            this.props = { ...this.props, style: [customProps.style, this.props.style] };
            try {
                return TextRender.apply(this, arguments);
            } finally {
                this.props = oldProps;
            }
        };
    }
}

simple solution I found

var today = new Date().valueOf();

console.log( today );

I believe it's included even in Edu version. Just right click the solid green arrow button (Run) and choose "Add parameters".

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

You can use .loc to select the specific columns with all rows and then pull that. An example is below:

pandas.merge(dataframe1, dataframe2.iloc[:, [0:5]], how='left', on='key')

In this example, you are merging dataframe1 and dataframe2. You have chosen to do an outer left join on 'key'. However, for dataframe2 you have specified .iloc which allows you to specific the rows and columns you want in a numerical format. Using :, your selecting all rows, but [0:5] selects the first 5 columns. You could use .loc to specify by name, but if your dealing with long column names, then .iloc may be better.

Assuming that you have a collection ${roles} of the elements to put in the combo, and ${selected} the selected element, It would go like this:

<select name='role'>
    <option value="${selected}" selected>${selected}</option>
    <c:forEach items="${roles}" var="role">
        <c:if test="${role != selected}">
            <option value="${role}">${role}</option>
        </c:if>
    </c:forEach>
</select>

UPDATE (next question)

You are overwriting the attribute "productSubCategoryName". At the end of the for loop, the last productSubCategoryName.

Because of the limitations of the expression language, I think the best way to deal with this is to use a map:

Map<String,Boolean> map = new HashMap<String,Boolean>();
for(int i=0;i<userProductData.size();i++){
    String productSubCategoryName=userProductData.get(i).getProductSubCategory();
    System.out.println(productSubCategoryName);
    map.put(productSubCategoryName, true);
}
request.setAttribute("productSubCategoryMap", map);

And then in the JSP:

<select multiple="multiple" name="prodSKUs">
    <c:forEach items="${productSubCategoryList}" var="productSubCategoryList">
        <option value="${productSubCategoryList}" ${not empty productSubCategoryMap[productSubCategoryList] ? 'selected' : ''}>${productSubCategoryList}</option>
    </c:forEach>
</select>

You are missing a :selected on the selector for show() - see the jQuery documentation for an example of how to use this.

In your case it will probably look something like this:

$('#'+$('#colorselector option:selected').val()).show();

Try add min-width: 100% to style of your textarea:

<textarea class="form-control" style="min-width: 100%"></textarea>

While you do the following, technically speaking:

<button ng-click="doSomething($event)"></button>

// In controller:
$scope.doSomething = function($event) {
  //reference to the button that triggered the function:
  $event.target

This is probably something you don't want to do as AngularJS philosophy is to focus on model manipulation and let AngularJS do the rendering (based on hints from the declarative UI). Manipulating DOM elements and attributes from a controller is a big no-no in AngularJS world.

You need to add a reference to System.Configuration and then use:

System.Configuration.ConfigurationManager.
    ConnectionStrings["connectionStringName"].ConnectionString;

You don't need floats. In fact, they're useless because floats are ignored in flexbox.

You also don't need CSS positioning.

There are several flex methods available. auto margins have been mentioned in another answer.

Here are two other options:

• Use justify-content: space-between and the order property.
• Use justify-content: space-between and reverse the order of the divs.

.parent {_x000D_
    display: flex;_x000D_
    justify-content: space-between;_x000D_
}_x000D_
_x000D_
.parent:first-of-type > div:last-child { order: -1; }_x000D_
_x000D_
p { background-color: #ddd;}

<p>Method 1: Use <code>justify-content: space-between</code> and <code>order-1</code></p>_x000D_
_x000D_
<div class="parent">_x000D_
    <div class="child" style="float:right"> Ignore parent? </div>_x000D_
    <div>another child </div>_x000D_
</div>_x000D_
_x000D_
<hr>_x000D_
_x000D_
<p>Method 2: Use <code>justify-content: space-between</code> and reverse the order of _x000D_
             divs in the mark-up</p>_x000D_
_x000D_
<div class="parent">_x000D_
    <div>another child </div>_x000D_
    <div class="child" style="float:right"> Ignore parent? </div>_x000D_
</div>

They sound about the same, however, the exit() also allows you to set the exit code of your PHP script.

Usually you don't really need this, but when writing console PHP scripts, you might want to check with for example Bash if the script completed everything in the right way.

Then you can use exit() and catch that later on. Die() however doesn't support that.

Die() always exists with code 0. So essentially a die() command does the following:

<?php
echo "I am going to die";
exit(0);
?>

Which is the same as:

<?php
die("I am going to die");
?>

You want the php function "asort":

http://php.net/manual/en/function.asort.php

it sorts the array, maintaining the index associations.

Edit: I've just noticed you're using a standard array (non-associative). if you're not fussed about preserving index associations, use sort():

http://php.net/manual/en/function.sort.php

If you are splitting from Linux, you can still reassemble in Windows.

we developed a module on GitHub that has hooks for fetching data so you can use it like this for your purpose:

import { useFetching } from "react-concurrent";

const app = () => {
  const { data, isLoading, error , refetch } = useFetching(() =>
    fetch("http://example.com"),
  );
};

You can fork that out, but any PRs are welcome. https://github.com/hosseinmd/react-concurrent#react-concurrent

In the Oracle RDBMS, it is possible to use a multi-row subquery in the select clause as long as the (sub-)output is encapsulated as a collection. In particular, a multi-row select clause subquery can output each of its rows as an xmlelement that is encapsulated in an xmlforest.

Googling around for Groovy ways to "cast" a String to a Date, I came across this article: http://www.goodercode.com/wp/intercept-method-calls-groovy-type-conversion/

The author uses Groovy metaMethods to allow dynamically extending the behavior of any class' asType method. Here is the code from the website.

class Convert {
    private from
    private to

    private Convert(clazz) { from = clazz }
    static def from(clazz) {
        new Convert(clazz)
    }

    def to(clazz) {
        to = clazz
        return this
    }

    def using(closure) {
        def originalAsType = from.metaClass.getMetaMethod('asType', [] as Class[])
        from.metaClass.asType = { Class clazz ->
            if( clazz == to ) {
                closure.setProperty('value', delegate)
                closure(delegate)
            } else {
                originalAsType.doMethodInvoke(delegate, clazz)
            }
        }
    }
}

They provide a Convert class that wraps the Groovy complexity, making it trivial to add custom as-based type conversion from any type to any other:

Convert.from( String ).to( Date ).using { new java.text.SimpleDateFormat('MM-dd-yyyy').parse(value) }

def christmas = '12-25-2010' as Date

It's a convenient and powerful solution, but I wouldn't recommend it to someone who isn't familiar with the tradeoffs and pitfalls of tinkering with metaClasses.

To remove the image in ImageView use:

title_image.setImageResource(-1);

it works for me

    $input = [1,2,1,3,2,4,10];
    //if give string
    //$input = "hello hello how are you how hello";
    //$array = explode(' ',$input);
    $count_val = [];
    foreach($array as $val){
      $count_val[$val]++;
    }
    print_r($count_val);
//output ( [1] => 2 [2] => 2 [3] => 1 [4] => 1 [10] => 1 )

A simple solution that works for pages without any query parameters, is browser back / forward, router and deep-linking compliant.

<a (click)="jumpToId('anchor1')">Go To Anchor 1</a>


ngOnInit() {

    // If your page is dynamic
    this.yourService.getWhatever()
        .then(
            data => {
            this.componentData = data;
            setTimeout(() => this.jumpToId( window.location.hash.substr(1) ), 100);
        }
    );

    // If your page is static
    // this.jumpToId( window.location.hash.substr(1) )
}

jumpToId( fragment ) {

    // Use the browser to navigate
    window.location.hash = fragment;

    // But also scroll when routing / deep-linking to dynamic page
    // or re-clicking same anchor
    if (fragment) {
        const element = document.querySelector('#' + fragment);
        if (element) element.scrollIntoView();
    }
}

The timeout is simply to allow the page to load any dynamic data "protected" by an *ngIf. This can also be used to scroll to the top of the page when changing route - just provide a default top anchor tag.

I use lipo command to combine two built static libraries manually.

EX: I have a static library(libXYZ.a) to build.

I run build for Generic iOS Device and got Product in Debug-iphoneos/

$ lipo -info Debug-iphoneos/libXYZ.a
Architectures in the fat file: Debug-iphoneos/libXYZ.a are: armv7 arm64

Then I run build for any iOS Simulator and got Product in Debug-iphonesimulator/

$ lipo -info Debug-iphonesimulator/libXYZ.a
Architectures in the fat file: Debug-iphonesimulator/libXYZ.a are: i386 x86_64

Finally I combine into one to contain all architectures.

$ lipo -create Debug-iphoneos/libXYZ.a Debug-iphonesimulator/libXYZ.a -output libXYZ.a
$ lipo -info libXYZ.a
Architectures in the fat file: libXYZ.a are: armv7 i386 x86_64 arm64

There is a rule in C++, for every new there is a delete.

1. Why won't the first case work? Seems the most straightforward use to use and delete a pointer? The error says the memory wasn't allocated but 'cout' returned an address.

new is never called. So the address that cout prints is the address of the memory location of myVar, or the value assigned to myPointer in this case. By writing:

myPointer = &myVar;

you say:

myPointer = The address of where the data in myVar is stored

2. On the second example the error is not being triggered but doing a cout of the value of myPointer still returns a memory address?

It returns an address that points to a memory location that has been deleted. Because first you create the pointer and assign its value to myPointer, second you delete it, third you print it. So unless you assign another value to myPointer, the deleted address will remain.

3. Does #3 really work? Seems to work to me, the pointer is no longer storing an address, is this the proper way to delete a pointer?

NULL equals 0, you delete 0, so you delete nothing. And it's logic that it prints 0 because you did:

myPointer = NULL;

which equals:

myPointer = 0;

One option is to use numba and the @jit or @njit decorator. I also made one or two little tweaks to your code (at least in Python 3, "list" is a keyword that shouldn't be used for a variable name):

@njit
def njit_product(lst):
    p = lst[0]  # first element
    for i in lst[1:]:  # loop over remaining elements
        p *= i
    return p

For timing purposes, you need to run once to compile the function first using numba. In general, the function will be compiled the first time it is called, and then called from memory after that (faster).

njit_product([1, 2])  # execute once to compile

Now when you execute your code, it will run with the compiled version of the function. I timed them using a Jupyter notebook and the %timeit magic function:

product(b)  # yours
# 32.7 µs ± 510 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)

njit_product(b)
# 92.9 µs ± 392 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)

Note that on my machine, running Python 3.5, the native Python for loop was actually the fastest. There may be a trick here when it comes to measuring numba-decorated performance with Jupyter notebooks and the %timeit magic function. I am not sure that the timings above are correct, so I recommend trying it out on your system and seeing if numba gives you a performance boost.

You need to enclose your <parent> elements in a surrounding element as XML Documents can have only one root node:

<parents> <!-- I've added this tag -->
    <parent>
        <child>
            Text
        </child>
    </parent>
    <parent>
        <child>
            <grandchild>
                Text
            </grandchild>
            <grandchild>
                Text
            </grandchild>
        </child>
        <child>
            Text
        </child>
    </parent>
</parents> <!-- I've added this tag -->

As you're receiving this markup from somewhere else, rather than generating it yourself, you may have to do this yourself by treating the response as a string and wrapping it with appropriate tags, prior to attempting to parse it as XML.

So, you've a couple of choices:

1. Get the provider of the web service to return you actual XML that has one root node
2. Pre-process the XML, as I've suggested above, to add a root node
3. Pre-process the XML to split it into multiple chunks (i.e. one for each <parent> node) and process each as a distinct XML Document

I hade same problem then i fixed like this

change "text/javascript"

i think unlink & link php versions are not enough because we are often using php with apache(httpd), so need to update httpd.conf after switch php version.

i have write shell script for disable/enable php_module automatically inside httpd.conf, look at line 46 to line 54 https://github.com/dangquangthai/switch-php-version-on-mac-sierra/blob/master/switch-php#L46

Follow my steps:

1) Check installed php versions by brew, for sure everything good

> brew list | grep php
#output
php56
php56-intl
php56-mcrypt
php71
php71-intl
php71-mcrypt

2) Run script

> switch-php 71 # or switch-php 56
#output
PHP version [71] found
Switching from [php56] to [php71] ... 
Unlink php56 ... [OK] and Link php71 ... [OK]
Updating Apache2.4 Configuration /usr/local/etc/httpd/httpd.conf ... [OK]
Restarting Apache2.4 ... [OK]
PHP 7.1.11 (cli) (built: Nov  3 2017 08:48:02) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies

3) Finally, when your got above message, check httpd.conf, in my laptop:

vi /usr/local/etc/httpd/httpd.conf

You can see near by LoadModule lines

LoadModule php7_module /usr/local/Cellar/php71/7.1.11_22/libexec/apache2/libphp7.so
#LoadModule php5_module /usr/local/Cellar/php56/5.6.32_8/libexec/apache2/libphp5.so

4) open httpd://localhost/info.php

i hope it helpful

I see you've already found out a solution, however I just wanted to add some information which may help someone trying to achieve the same thing with big POST requests.

I had the same issue a couple of weeks ago, indeed it isn't possible to achieve a "clean" download through AJAX, the Filament Group created a jQuery plugin which works exactly how you've already found out, it is called jQuery File Download however there is a downside to this technique.

If you're sending big requests through AJAX (say files +1MB) it will negatively impact responsiveness. In slow Internet connections you'll have to wait a lot until the request is sent and also wait for the file to download. It isn't like an instant "click" => "popup" => "download start". It's more like "click" => "wait until data is sent" => "wait for response" => "download start" which makes it appear the file double its size because you'll have to wait for the request to be sent through AJAX and get it back as a downloadable file.

If you're working with small file sizes <1MB you won't notice this. But as I discovered in my own app, for bigger file sizes it is almost unbearable.

My app allow users to export images dynamically generated, these images are sent through POST requests in base64 format to the server (it is the only possible way), then processed and sent back to users in form of .png, .jpg files, base64 strings for images +1MB are huge, this force users to wait more than necessary for the file to start downloading. In slow Internet connections it can be really annoying.

My solution for this was to temporary write the file to the server, once it is ready, dynamically generate a link to the file in form of a button which changes between "Please wait..." and "Download" states and at the same time, print the base64 image in a preview popup window so users can "right-click" and save it. This makes all the waiting time more bearable for users, and also speed things up.

Update Sep 30, 2014:

Months have passed since I posted this, finally I've found a better approach to speed things up when working with big base64 strings. I now store base64 strings into the database (using longtext or longblog fields), then I pass its record ID through the jQuery File Download, finally on the download script file I query the database using this ID to pull the base64 string and pass it through the download function.

Download Script Example:

<?php
// Record ID
$downloadID = (int)$_POST['id'];
// Query Data (this example uses CodeIgniter)
$data       = $CI->MyQueries->GetDownload( $downloadID );
// base64 tags are replaced by [removed], so we strip them out
$base64     = base64_decode( preg_replace('#\[removed\]#', '', $data[0]->image) );
// This example is for base64 images
$imgsize    = getimagesize( $base64 );
// Set content headers
header('Content-Disposition: attachment; filename="my-file.png"');
header('Content-type: '.$imgsize['mime']);
// Force download
echo $base64;
?>

I know this is way beyond what the OP asked, however I felt it would be good to update my answer with my findings. When I was searching for solutions to my problem, I read lots of "Download from AJAX POST data" threads which didn't give me the answer I was looking for, I hope this information helps someone looking to achieve something like this.

You mention adding the additional include directory (C/C++|General) and additional lib dependency (Linker|Input), but have you also added the additional library directory (Linker|General)?

Including a sample error message might also help people answer the question since it's not even clear if the error is during compilation or linking.

Use the vlookup function.

Put both sets of data in the same excel file, on different sheets. Then, in the column next to the 805 row set (which I assume is on sheet2), enter

=if(isna(vlookup(A1, Sheet1!$A$1:$A$800, 1, false)), 0, 1)

The column will contain 0 for values that are not found in the other sheet, and 1 for values that are. You can sort the sheet to find all the missing values.

                src: imageval
            });
            $(".thumnail-zoomed-wrapper").fadeIn();
            return false;

Here's an extremely simple answer

yourPlot +
  theme(
    panel.border = element_blank(), 
    panel.grid.major = element_blank(),
    panel.grid.minor = element_blank(), 
    axis.line = element_line(colour = "black")
    )

It's that easy. Source: the end of this article

You have to escape the backslash, so try this:

str = "Hello\\nWorld";

Here are more escaped characters in Javascript.

I just ran into this today and it was because the server I was trying to connect to was overloaded with processing. So it may be possible that the server is low on memory or CPU starved.

Thanks Mr. Tom Chantler adding that to get the exe http://downloadsvn.codeplex.com/ to pull the SVN source

just note that suppose you're downloading the below project: you have to enter exactly the following to donwload it in the exe URL:

http://myproject.googlecode.com/svn/trunk/

developer not taking care of appending the h t t p : / / if it does not exist. Hope it saves somebody's time.

Reasoning for my CSS styles not being applied, even though they were being loaded:

The media attribute on the link tag which was loading the stylesheet had an incorrect value. I had inadvertently set it to 1 instead of all. This meant the browser was ignoring those styles in that linked stylesheet.

Broken:

<link rel="stylesheet" type="text/css" href="css/style.css" media="1" />

Corrected:

<link rel="stylesheet" type="text/css" href="css/style.css" media="all" />

If you set a different field separator, you can directly use a for loop:

IFS=","
for v in $variable
do
   # things with "$v" ...
done

You can also store the values in an array and then loop through it as indicated in How do I split a string on a delimiter in Bash?:

IFS=, read -ra values <<< "$variable"
for v in "${values[@]}"
do
   # things with "$v"
done

Test

$ variable="abc,def,ghij"
$ IFS=","
$ for v in $variable
> do
> echo "var is $v"
> done
var is abc
var is def
var is ghij

You can find a broader approach in this solution to How to iterate through a comma-separated list and execute a command for each entry.

Examples on the second approach:

$ IFS=, read -ra vals <<< "abc,def,ghij"
$ printf "%s\n" "${vals[@]}"
abc
def
ghij
$ for v in "${vals[@]}"; do echo "$v --"; done
abc --
def --
ghij --

JavaScript is a dynamically typed language. This means that you never need to declare the type of a function argument (or any other variable). So, your code will work as long as arrayP is an array and contains elements with a value property.

WAMP USERS:

1) Go to C:\wamp\apps\phpmyadmin

2) Open config.inc

3) Add $cfg['ExecTimeLimit'] = ’3600'; to the file.

4) Save the file and restart the server.

This file overwrites the php.ini and will work for you!

Try this:

$('#contra').focusout(function (){
    $('#btnPassword').focus();
});

Black text with white shadow

Another way, I used for white shadow (on text): create a clone for shadow:

Note: This require xmlns:xlink="http://www.w3.org/1999/xlink" at SVG declaration.

Real text value is located in <defs> section, with position and style, but without a fill definition.

The text is cloned two times: first for shadow and second for the text itself.

<svg xmlns="http://www.w3.org/2000/svg" width="640" height="70"_x000D_
    xmlns:xlink="http://www.w3.org/1999/xlink">_x000D_
  <defs>_x000D_
  <filter id="Blur"><feGaussianBlur stdDeviation="0.8" /></filter>_x000D_
  <text style="font-family:sans,helvetica;font-weight:bold;font-size:12pt"_x000D_
      id="Text"><tspan x="12" y="19">_x000D_
        Black text with white shadow_x000D_
    </tspan></text>_x000D_
  </defs>_x000D_
  <rect style="fill:#8AB" width="640" height="70" />_x000D_
  <use style="fill:white;" filter="url(#Blur)" xlink:href="#Text"_x000D_
      transform="translate(1.8,.9)"/>_x000D_
  <use style="fill:black;" xlink:href="#Text"/>_x000D_
</svg>

More distant shadow with biggest value as blur deviation:

<svg xmlns="http://www.w3.org/2000/svg" width="640" height="70"_x000D_
    xmlns:xlink="http://www.w3.org/1999/xlink">_x000D_
  <defs>_x000D_
  <filter id="Blur"><feGaussianBlur stdDeviation="3" /></filter>_x000D_
  <text style="font-family:sans,helvetica;font-weight:bold;font-size:12pt"_x000D_
      id="Text"><tspan x="12" y="19">_x000D_
        Black text with white shadow_x000D_
    </tspan></text>_x000D_
  </defs>_x000D_
  <rect style="fill:#8AB" width="640" height="70" />_x000D_
  <use style="fill:white;" filter="url(#Blur)" xlink:href="#Text"_x000D_
      transform="translate(7,5)"/>_x000D_
  <use style="fill:black;" xlink:href="#Text"/>_x000D_
</svg>

You can use this same approach with regular SVG objects.

With same requirement: No fill definition at <defs> section!

    xmlns:xlink="http://www.w3.org/1999/xlink">_x000D_

For CentOS/RHEL:

yum install mysql-devel -y

If you are using an <img> tag for the SVG, then you cannot manipulate its contents (as far as I know).

As the accepted answer shows, using <object> is an option.

I needed this recently and used gulp-inject during my gulp build to inject the contents of an SVG file directly into the HTML document as an <svg> element, which is then very easy to work with using CSS selectors and querySelector/getElementBy*.

This is an equivalent solution to Tim Pietzcker's answer (see also comments of same answer):

^(?!.*filename\.js$).*\.js$

It means, match *.js except *filename.js.

To get to this solution, you can check which patterns the negative lookbehind excludes, and then exclude exactly these patterns with a negative lookahead.

Going off of @Rok Kralj answer (best IMO) to check if any of needles exist in the haystack, you can use (bool) instead of !! which sometimes can be confusing during code review.

function in_array_any($needles, $haystack) {
   return (bool)array_intersect($needles, $haystack);
}

echo in_array_any( array(3,9), array(5,8,3,1,2) ); // true, since 3 is present
echo in_array_any( array(4,9), array(5,8,3,1,2) ); // false, neither 4 nor 9 is present

On mac:

• open terminal and run defaults write com.apple.finder AppleShowAllFiles YES anywhere.

• restart finder so you can see hidden files: command + option + escape ---> Relaunch

Then create a text file and you will be able to change the file extension to .gitignore

this introspection is intended to help debugging and development; it's not advisable to rely on it for production-functionality purposes.

URLEncoder is the way to go. You only need to keep in mind to encode only the individual query string parameter name and/or value, not the entire URL, for sure not the query string parameter separator character & nor the parameter name-value separator character =.

String q = "random word £500 bank $";
String url = "https://example.com?q=" + URLEncoder.encode(q, StandardCharsets.UTF_8);

When you're still not on Java 10 or newer, then use StandardCharsets.UTF_8.toString() as charset argument, or when you're still not on Java 7 or newer, then use "UTF-8".

Note that spaces in query parameters are represented by +, not %20, which is legitimately valid. The %20 is usually to be used to represent spaces in URI itself (the part before the URI-query string separator character ?), not in query string (the part after ?).

Also note that there are three encode() methods. One without Charset as second argument and another with String as second argument which throws a checked exception. The one without Charset argument is deprecated. Never use it and always specify the Charset argument. The javadoc even explicitly recommends to use the UTF-8 encoding, as mandated by RFC3986 and W3C.

All other characters are unsafe and are first converted into one or more bytes using some encoding scheme. Then each byte is represented by the 3-character string "%xy", where xy is the two-digit hexadecimal representation of the byte. The recommended encoding scheme to use is UTF-8. However, for compatibility reasons, if an encoding is not specified, then the default encoding of the platform is used.

Fetch Numbers:

return string.Concat(input.Where(char.IsNumber));

Fetch Letters:

return string.Concat(input.Where(char.IsLetter));

This error is usually encountered when inserting a record in a table where one of the columns is a VARCHAR or CHAR data type and the length of the value being inserted is longer than the length of the column.

I am not satisfied how Microsoft decided to inform with this "dry" response message, without any point of where to look for the answer.

Balanced tree is a tree whose height is of order of log(number of elements in the tree).

height = O(log(n))
O, as in asymptotic notation i.e. height should have same or lower asymptotic
growth rate than log(n)
n: number of elements in the tree

The definition given "a tree is balanced of each sub-tree is balanced and the height of the two sub-trees differ by at most one" is followed by AVL trees.

Since, AVL trees are balanced but not all balanced trees are AVL trees, balanced trees don't hold this definition and internal nodes can be unbalanced in them. However, AVL trees require all internal nodes to be balanced.

I think mixing @ShaunBouckaert and Mar 19 '09 at 16:22 answers is a good compromise :

" Reset highlighted search

Press Enter and the highlighted text is no longer highlighted, while search highlighting is still enabled.

I would check that the file is not empty first:

import os

scores = {} # scores is an empty dict already

if os.path.getsize(target) > 0:      
    with open(target, "rb") as f:
        unpickler = pickle.Unpickler(f)
        # if file is not empty scores will be equal
        # to the value unpickled
        scores = unpickler.load()

Also open(target, 'a').close() is doing nothing in your code and you don't need to use ;.

• Just try to cancel the "Downloading Components" from upper right corner 'X' button.
• A dialog box will appear then click OK (wait a bit for first time launch)

A today extension would be the most fitting solution.

Also you could do something on the lock screen with local notifications queued up to fire at regular intervals showing the latest countdown value.

In ASP.NET MVC 3 you can simply add your list to ViewData...

var options = new List<SelectListItem>();

options.Add(new SelectListItem { Value = "1", Text = "1" });
options.Add(new SelectListItem { Value = "2", Text = "2" });
options.Add(new SelectListItem { Value = "3", Text = "3", Selected = true });

ViewData["options"] = options;

...and then reference it by name in your razor view...

@Html.DropDownList("options")

You don't have to manually "use" the list in the DropDownList call. Doing it this way correctly set the selected value for me too.

Disclaimer:

1. Haven't tried this with the web forms view engine, but it should work too.
2. I haven't tested this in the v1 and v2, but it might work.

Use RETURN QUERY:

CREATE OR REPLACE FUNCTION word_frequency(_max_tokens int)
  RETURNS TABLE (txt   text   -- also visible as OUT parameter inside function
               , cnt   bigint
               , ratio bigint) AS
$func$
BEGIN
   RETURN QUERY
   SELECT t.txt
        , count(*) AS cnt                 -- column alias only visible inside
        , (count(*) * 100) / _max_tokens  -- I added brackets
   FROM  (
      SELECT t.txt
      FROM   token t
      WHERE  t.chartype = 'ALPHABETIC'
      LIMIT  _max_tokens
      ) t
   GROUP  BY t.txt
   ORDER  BY cnt DESC;                    -- potential ambiguity 
END
$func$  LANGUAGE plpgsql;

Call:

SELECT * FROM word_frequency(123);

Explanation:

• It is much more practical to explicitly define the return type than simply declaring it as record. This way you don't have to provide a column definition list with every function call. RETURNS TABLE is one way to do that. There are others. Data types of OUT parameters have to match exactly what is returned by the query.

• Choose names for OUT parameters carefully. They are visible in the function body almost anywhere. Table-qualify columns of the same name to avoid conflicts or unexpected results. I did that for all columns in my example.

  But note the potential naming conflict between the OUT parameter cnt and the column alias of the same name. In this particular case (RETURN QUERY SELECT ...) Postgres uses the column alias over the OUT parameter either way. This can be ambiguous in other contexts, though. There are various ways to avoid any confusion:

  1. Use the ordinal position of the item in the SELECT list: ORDER BY 2 DESC. Example:
     • Select first row in each GROUP BY group?
  2. Repeat the expression ORDER BY count(*).
  3. (Not applicable here.) Set the configuration parameter plpgsql.variable_conflict or use the special command #variable_conflict error | use_variable | use_column in the function. See:
     • Naming conflict between function parameter and result of JOIN with USING clause

• Don't use "text" or "count" as column names. Both are legal to use in Postgres, but "count" is a reserved word in standard SQL and a basic function name and "text" is a basic data type. Can lead to confusing errors. I use txt and cnt in my examples.

• Added a missing ; and corrected a syntax error in the header. (_max_tokens int), not (int maxTokens) - type after name.

• While working with integer division, it's better to multiply first and divide later, to minimize the rounding error. Even better: work with numeric (or a floating point type). See below.

Alternative

This is what I think your query should actually look like (calculating a relative share per token):

CREATE OR REPLACE FUNCTION word_frequency(_max_tokens int)
  RETURNS TABLE (txt            text
               , abs_cnt        bigint
               , relative_share numeric) AS
$func$
BEGIN
   RETURN QUERY
   SELECT t.txt, t.cnt
        , round((t.cnt * 100) / (sum(t.cnt) OVER ()), 2)  -- AS relative_share
   FROM  (
      SELECT t.txt, count(*) AS cnt
      FROM   token t
      WHERE  t.chartype = 'ALPHABETIC'
      GROUP  BY t.txt
      ORDER  BY cnt DESC
      LIMIT  _max_tokens
      ) t
   ORDER  BY t.cnt DESC;
END
$func$  LANGUAGE plpgsql;

The expression sum(t.cnt) OVER () is a window function. You could use a CTE instead of the subquery - pretty, but a subquery is typically cheaper in simple cases like this one.

A final explicit RETURN statement is not required (but allowed) when working with OUT parameters or RETURNS TABLE (which makes implicit use of OUT parameters).

round() with two parameters only works for numeric types. count() in the subquery produces a bigint result and a sum() over this bigint produces a numeric result, thus we deal with a numeric number automatically and everything just falls into place.

Not sure what you are really after but if you want to print exactly what you have you can do:

Option 1

print(df['Item'].to_csv(index=False))

Sweet
Candy
Chocolate

Option 2

for v in df['Item']:
    print(v)

Sweet
Candy
Chocolate

To further add missing points here, as per the request by Jaskey

Database version is stored within the SQLite database file.

catch is the constructor

SQLiteOpenHelper(Context context, String name, SQLiteDatabase.CursorFactory factory, int version)

So when the database helper constructor is called with a name (2nd param), platform checks if the database exists or not and if the database exists, it gets the version information from the database file header and triggers the right call back

As already explained in the older answer, if the database with the name doesn't exists, it triggers onCreate.

Below explanation explains onUpgrade case with an example.

Say, your first version of application had the DatabaseHelper (extending SQLiteOpenHelper) with constructor passing version as 1 and then you provided an upgraded application with the new source code having version passed as 2, then automatically when the DatabaseHelper is constructed, platform triggers onUpgrade by seeing the file already exists, but the version is lower than the current version which you have passed.

Now say you are planing to give a third version of application with db version as 3 (db version is increased only when database schema is to be modified). In such incremental upgrades, you have to write the upgrade logic from each version incrementally for a better maintainable code

Example pseudo code below:

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
  switch(oldVersion) {
    case 1:
       //upgrade logic from version 1 to 2
    case 2:
       //upgrade logic from version 2 to 3
    case 3:
       //upgrade logic from version 3 to 4
       break;
    default:
       throw new IllegalStateException(
                "onUpgrade() with unknown oldVersion " + oldVersion);
  }
}

Notice the missing break statement in case 1 and 2. This is what I mean by incremental upgrade.

Say if the old version is 2 and new version is 4, then the logic will upgrade the database from 2 to 3 and then to 4

If old version is 3 and new version is 4, it will just run the upgrade logic for 3 to 4

There will definitely be a bean also containing fields related to Birthday So use this and your issue will be resolved

@SpringBootApplication
@EntityScan("com.java.model*")  // base package where bean is present
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

If that field is bound to an entity (is a property of that entity) you can just set a default value for it.

An example:

public function getMyField() {
    if (is_null($this->MyField)) {
        $this->setMyField('my default value');
    }
    return $this->MyField;
}

They are different functions. You should decide for your situation what do you need.

I don't consider using any of them as a bad practice. Most of the time IsNullOrEmpty() is enough. But you have the choice :)

NAudio wraps the WaveOutXXXX API. I haven't looked at the source, but if NAudio exposes the waveOutWrite() function in a way that doesn't automatically stop playback on each call, then you should be able to do what you really want, which is to start playing the audio stream before you've received all the data.

Using the waveOutWrite() function allows you to "read ahead" and dump smaller chunks of audio into the output queue - Windows will automatically play the chunks seamlessly. Your code would have to take the compressed audio stream and convert it to small chunks of WAV audio on the fly; this part would be really difficult - all the libraries and components I've ever seen do MP3-to-WAV conversion an entire file at a time. Probably your only realistic chance is to do this using WMA instead of MP3, because you can write simple C# wrappers around the multimedia SDK.

Quick guide:

• Download Google USB Driver

• Connect your device with Android Debugging enabled to your PC

• Open Device Manager of Windows from System Properties.

• Your device should appear under Other devices listed as something like Android ADB Interface or 'Android Phone' or similar. Right-click that and click on Update Driver Software...

• Select Browse my computer for driver software

• Select Let me pick from a list of device drivers on my computer

• Double-click Show all devices

• Press the Have disk button

• Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf

• Select Android ADB Interface from the list of device types.

• Press the Yes button

• Press the Install button

• Press the Close button

Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.

Python cares about indents

Let me recommend you using Selenide library. It allows writing much more concise and readable tests. It can wait for presence of elements with much shorter syntax:

$("#elementId").shouldBe(visible);

Here is a sample project for testing Google search: https://github.com/selenide-examples/google

If you don't want to import csv module for that, you can write a list of lists to a csv file using only Python built-ins

with open("output.csv", "w") as f:
    for row in a:
        f.write("%s\n" % ','.join(str(col) for col in row))

In Linux, Open the VIM configuration file

$ sudo -H gedit /etc/vim/vimrc

Added following lines:

set fileencodings=utf-8,ucs-bom,gb18030,gbk,gb2312,cp936
set termencoding=utf-8
set encoding=utf-8

Save and exit, and terminal command:

$ source /etc/vim/vimrc

At this time VIM will correctly display Chinese.

Functions cannot be used to modify base table information, use a stored procedure.

For modifying the status I think a RESTful approach is to use a logical sub-resource which describes the status of the resources. This IMO is pretty useful and clean when you have a reduced set of statuses. It makes your API more expressive without forcing the existing operations for your customer resource.

Example:

POST /customer/active  <-- Providing entity in the body a new customer
{
  ...  // attributes here except status
}

The POST service should return the newly created customer with the id:

{
    id:123,
    ...  // the other fields here
}

The GET for the created resource would use the resource location:

GET /customer/123/active

A GET /customer/123/inactive should return 404

For the PUT operation, without providing a Json entity it will just update the status

PUT /customer/123/inactive  <-- Deactivating an existing customer

Providing an entity will allow you to update the contents of the customer and update the status at the same time.

PUT /customer/123/inactive
{
    ...  // entity fields here except id and status
}

You are creating a conceptual sub-resource for your customer resource. It is also consistent with Roy Fielding's definition of a resource: "...A resource is a conceptual mapping to a set of entities, not the entity that corresponds to the mapping at any particular point in time..." In this case the conceptual mapping is active-customer to customer with status=ACTIVE.

Read operation:

GET /customer/123/active 
GET /customer/123/inactive

If you make those calls one right after the other one of them must return status 404, the successful output may not include the status as it is implicit. Of course you can still use GET /customer/123?status=ACTIVE|INACTIVE to query the customer resource directly.

The DELETE operation is interesting as the semantics can be confusing. But you have the option of not publishing that operation for this conceptual resource, or use it in accordance with your business logic.

DELETE /customer/123/active

That one can take your customer to a DELETED/DISABLED status or to the opposite status (ACTIVE/INACTIVE).

It is impossible to safely escape a string without a DB connection. mysql_real_escape_string() and prepared statements need a connection to the database so that they can escape the string using the appropriate character set - otherwise SQL injection attacks are still possible using multi-byte characters.

If you are only testing, then you may as well use mysql_escape_string(), it's not 100% guaranteed against SQL injection attacks, but it's impossible to build anything safer without a DB connection.

I guess, a column value in a foreign key table should match with the column value of the primary key table. If we are trying to create a foreign key constraint between two tables where the value inside one column(going to be the foreign key) is different from the column value of the primary key table then it will throw the message.

So it is always recommended to insert only those values in the Foreign key column which are present in the Primary key table column.

For ex. If the Primary table column has values 1, 2, 3 and in Foreign key column the values inserted are different, then the query would not be executed as it expects the values to be between 1 & 3.

As others said, class variables are shared between a given class and its subclasses. Class instance variables belong to exactly one class; its subclasses are separate.

Why does this behavior exist? Well, everything in Ruby is an object—even classes. That means that each class has an object of the class Class (or rather, a subclass of Class) corresponding to it. (When you say class Foo, you're really declaring a constant Foo and assigning a class object to it.) And every Ruby object can have instance variables, so class objects can have instance variables, too.

The trouble is, instance variables on class objects don't really behave the way you usually want class variables to behave. You usually want a class variable defined in a superclass to be shared with its subclasses, but that's not how instance variables work—the subclass has its own class object, and that class object has its own instance variables. So they introduced separate class variables with the behavior you're more likely to want.

In other words, class instance variables are sort of an accident of Ruby's design. You probably shouldn't use them unless you specifically know they're what you're looking for.

Answer covering Java >= 9:

For Java 9+, the JVM option needs a slight change by prefixing the address with the IP address of the machine hosting the JVM, or just *:

-agentlib:jdwp=transport=dt_socket,server=y,address=*:8000,suspend=n

This is due to a change noted in https://www.oracle.com/technetwork/java/javase/9-notes-3745703.html#JDK-8041435.

For Java < 9, the port number is enough to connect.

Check the configurations in {M2_HOME}\conf\setting.xml as mentioned in the following link.

http://www.mkyong.com/maven/where-is-maven-local-repository/

Hope this helps.

You can also use the Uri class.

new Uri("file:///Users/smcho/filegen_from_directory/AIRPassthrough").Segments.Last()

You may prefer to use this class if you want to get some other segment, or if you want to do the same thing with a web address.

Use SQL Server Object Explorer (SSOX) Instead

Unlike the other answers, this approach uses:
- No special commands.
- No complicated configurations.
Just use the SQL Server Object Explorer

It's pretty straightforward...

• From the View menu, open SQL Server Object Explorer.

• Right click on the {YourTableName} table > View Designer

Done.

All you'd need in your case is:

return expression;

The reason why is that the expression itself evaluates to a boolean value of true or false, so it's redundant to have an if block (or even a ?: operator).

This should work:

 cat "$API" >> "$CONFIG"

You need to use the >> operator to append to a file. Redirecting with > causes the file to be overwritten. (truncated).

you need to take out the quotes:

soda = a + b

(You want to refer to the variables a and b, not the strings "a" and "b")

Here is one approach. ifelse is vectorized and it checks all rows for zero values of b and replaces est with (a - 5)/2.53 if that is the case.

df <- transform(df, est = ifelse(b == 0, (a - 5)/2.53, est))

You can do this:

conf.CreateMap<SourceType, DestinationType>()
   .ForSourceMember(x => x.SourceProperty, y => y.Ignore());

Or, in latest version of Automapper, you simply want to tell Automapper to not validate the field

conf.CreateMap<SourceType, DestinationType>()
   .ForSourceMember(x => x.SourceProperty, y => y.DoNotValidate());

The line function implementation should be:

void addStudent(struct student person) {

}

person is not a type but a variable, you cannot use it as the type of a function parameter.

Also, make sure your struct is defined before the prototype of the function addStudent as the prototype uses it.

Not sure why you'd want to, but the C# way would be

string[] newArray = new string[0];

I'm guessing that VB won't be too dissimilar to this.

If you're building an empty array so you can populate it with values later, you really should consider using

List<string>

and converting it to an array (if you really need it as an array) with

newListOfString.ToArray();

Do you mean altering the table after it has been created? If so you need to use alter table, in particular:

ALTER TABLE tablename MODIFY COLUMN new-column-definition

e.g.

ALTER TABLE test MODIFY COLUMN locationExpect VARCHAR(120);

If you want to get rid of the extra xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" and xmlns:xsd="http://www.w3.org/2001/XMLSchema", but still keep your own namespace xmlns="http://schemas.YourCompany.com/YourSchema/", you use the same code as above except for this simple change:

//  Add lib namespace with empty prefix  
ns.Add("", "http://schemas.YourCompany.com/YourSchema/");   

You can solve the negative bearing problem by adding 360°. Unfortunately, this might result in bearings larger than 360° for positive bearings. This is a good candidate for the modulo operator, so all in all you should add the line

Bearing = (Bearing + 360) % 360

at the end of your method.

SELECT created
  FROM dba_objects
 WHERE object_name = <<your table name>>
   AND owner = <<owner of the table>>
   AND object_type = 'TABLE'

will tell you when a table was created (if you don't have access to DBA_OBJECTS, you could use ALL_OBJECTS instead assuming you have SELECT privileges on the table).

The general answer to getting timestamps from a row, though, is that you can only get that data if you have added columns to track that information (assuming, of course, that your application populates the columns as well). There are various special cases, however. If the DML happened relatively recently (most likely in the last couple hours), you should be able to get the timestamps from a flashback query. If the DML happened in the last few days (or however long you keep your archived logs), you could use LogMiner to extract the timestamps but that is going to be a very expensive operation particularly if you're getting timestamps for many rows. If you build the table with ROWDEPENDENCIES enabled (not the default), you can use

SELECT scn_to_timestamp( ora_rowscn ) last_modified_date,
       ora_rowscn last_modified_scn,
       <<other columns>>
  FROM <<your table>>

to get the last modification date and SCN (system change number) for the row. By default, though, without ROWDEPENDENCIES, the SCN is only at the block level. The SCN_TO_TIMESTAMP function also isn't going to be able to map SCN's to timestamps forever.

You could create a little class that returns the boolean result of calling match, and retains the matched groups for subsequent retrieval:

import re

class REMatcher(object):
    def __init__(self, matchstring):
        self.matchstring = matchstring

    def match(self,regexp):
        self.rematch = re.match(regexp, self.matchstring)
        return bool(self.rematch)

    def group(self,i):
        return self.rematch.group(i)


for statement in ("I love Mary", 
                  "Ich liebe Margot", 
                  "Je t'aime Marie", 
                  "Te amo Maria"):

    m = REMatcher(statement)

    if m.match(r"I love (\w+)"): 
        print "He loves",m.group(1) 

    elif m.match(r"Ich liebe (\w+)"):
        print "Er liebt",m.group(1) 

    elif m.match(r"Je t'aime (\w+)"):
        print "Il aime",m.group(1) 

    else: 
        print "???"

Update for Python 3 print as a function, and Python 3.8 assignment expressions - no need for a REMatcher class now:

import re

for statement in ("I love Mary",
                  "Ich liebe Margot",
                  "Je t'aime Marie",
                  "Te amo Maria"):

    if m := re.match(r"I love (\w+)", statement):
        print("He loves", m.group(1))

    elif m := re.match(r"Ich liebe (\w+)", statement):
        print("Er liebt", m.group(1))

    elif m := re.match(r"Je t'aime (\w+)", statement):
        print("Il aime", m.group(1))

    else:
        print()

A related note

To grep for carriage return, namely the \r character, or 0x0d, we can do this:

grep -F $'\r' application.log

Alternatively, use printf, or echo, for POSIX compatibility

grep -F "$(printf '\r')" application.log

And we can use hexdump, or less to see the result:

$ printf "a\rb" | grep -F $'\r' | hexdump -c
0000000   a  \r   b  \n

Regarding the use of $'\r' and other supported characters, see Bash Manual > ANSI-C Quoting:

Words of the form $'string' are treated specially. The word expands to string, with backslash-escaped characters replaced as specified by the ANSI C standard

It looks like you're comparing strings incorrectly. To compare a string to another, use the std::string::compare function.

Example

     while ((wrong < MAX_WRONG) && (soFar.compare(THE_WORD) != 0)) 

Well for the very basics you can try aligning them in the table. However the use of table is bad for layout since table is meant for contents.

What you can use is CSS floating techniques.

CSS Code

.styleform label{float:left;}
.styleform input{margin-left:200px;} /* this gives space for the label on the left */
.styleform .clear{clear:both;} /* prevent elements from stacking weirdly */

HTML

<div class="styleform">
<form>
<label>First Name:</label><input type="text" name="first" /><div class="clear"></div>
<label>Last Name:</label><input type="text" name="first" /><div class="clear"></div>
<label>Email:</label><input type="text" name="first" /><div class="clear"></div>
</form>
</div>

An elaborated article I wrote can be found answering the question of IE7 float problem: IE7 float right problems

Think about somebody doing help(yourmodule) at the interactive interpreter's prompt — what do they want to know? (Other methods of extracting and displaying the information are roughly equivalent to help in terms of amount of information). So if you have in x.py:

"""This module does blah blah."""

class Blah(object):
  """This class does blah blah."""

then:

>>> import x; help(x)

shows:

Help on module x:

NAME
    x - This module does blah blah.

FILE
    /tmp/x.py

CLASSES
    __builtin__.object
        Blah

    class Blah(__builtin__.object)
     |  This class does blah blah.
     |  
     |  Data and other attributes defined here:
     |  
     |  __dict__ = <dictproxy object>
     |      dictionary for instance variables (if defined)
     |  
     |  __weakref__ = <attribute '__weakref__' of 'Blah' objects>
     |      list of weak references to the object (if defined)

As you see, the detailed information on the classes (and functions too, though I'm not showing one here) is already included from those components' docstrings; the module's own docstring should describe them very summarily (if at all) and rather concentrate on a concise summary of what the module as a whole can do for you, ideally with some doctested examples (just like functions and classes ideally should have doctested examples in their docstrings).

I don't see how metadata such as author name and copyright / license helps the module's user — it can rather go in comments, since it could help somebody considering whether or not to reuse or modify the module.

For some reason the round() method doesn't work if you have float numbers with many decimal places, but this will.

decimals = 2    
df['column'] = df['column'].apply(lambda x: round(x, decimals))

return dataSource.getParkingLots()
                 .stream()
                 .filter(parkingLot -> Objects.equals(parkingLot.getId(), id))
                 .findFirst()
                 .orElse(null);

I had to filter out only one object from a list of objects. So i used this, hope it helps.

The same way Steven Schmatz did it but using Swift 3.0 :

//max Length
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange,
               replacementString string: String) -> Bool
{
    let maxLength = 4
    let currentString: NSString = textField.text! as NSString
    let newString: NSString = currentString.replacingCharacters(in: range, with: string) as NSString
    return newString.length <= maxLength
}

Not jQuery, as the question asks for, but natively (i.e., no libraries required) I think the better tool for the job is querySelector to get a single instance of a selector:

let el = document.querySelector('img');
console.log(el);

For all matching instances, use document.querySelectorAll(), or for those within another element you can chain as follows:

// Get some wrapper, with class="parentClassName"
let parentEl = document.querySelector('.parentClassName');
// Get all img tags within the parent element by parentEl variable
let childrenEls = parentEl.querySelectorAll('img');

Note the above is equivalent to:

let childrenEls = document.querySelector('.parentClassName').querySelectorAll('img');

In 2019, I would suggest putting all the item animations into the ItemAnimator.

Let's start with declaring the animator in the recycler-view:

with(view.recycler_view) {
adapter = Adapter()
itemAnimator = CustomAnimator()
}

Declare the custom animator then,

class CustomAnimator() : DefaultItemAnimator() {

     override fun animateAppearance(
       holder: RecyclerView.ViewHolder,
       preInfo: ItemHolderInfo?,
       postInfo: ItemHolderInfo): Boolean{} // declare  what happens when a item appears on the recycler view

     override fun animatePersistence(
       holder: RecyclerView.ViewHolder,
       preInfo: ItemHolderInfo,
       postInfo: ItemHolderInfo): Boolean {} // declare animation for items that persist in a recycler view even when the items change

}

Similar to the ones above there is one for disappearance animateDisappearance, for add animateAdd, for change animateChange and move animateMove.

One important point would be to call the correct animation-dispatchers inside them.

Just to add to Ned's answer above: you can use this to redirect output to any object that implements a write(str) method.

This can be used to good effect to "catch" stdout output in a GUI application.

Here's a silly example in PyQt:

import sys
from PyQt4 import QtGui

class OutputWindow(QtGui.QPlainTextEdit):
    def write(self, txt):
        self.appendPlainText(str(txt))

app = QtGui.QApplication(sys.argv)
out = OutputWindow()
sys.stdout=out
out.show()
print "hello world !"

Edit: As in a comment rightly requested here some more information. Use the include tag

<include
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   layout="@layout/yourlayout" />

to include the layout you want to reuse.

If you installed Python 2.7, I think you could use pip2 and pip2.7 to install packages specifically for Python 2, like

pip2 install some_pacakge

or

pip2.7 install some_package

And you may use pip3 or pip3.5 to install pacakges specifically for Python 3.

.csv or POI will certainly do it, but you should be aware of Andy Khan's JExcel. I think it's by far the best Java library for working with Excel there is.
