Here is another option.

os.scandir(path='.')

It returns an iterator of os.DirEntry objects corresponding to the entries (along with file attribute information) in the directory given by path.

Example:

with os.scandir(path) as it:
    for entry in it:
        if not entry.name.startswith('.'):
            print(entry.name)

Using scandir() instead of listdir() can significantly increase the performance of code that also needs file type or file attribute information, because os.DirEntry objects expose this information if the operating system provides it when scanning a directory. All os.DirEntry methods may perform a system call, but is_dir() and is_file() usually only require a system call for symbolic links; os.DirEntry.stat() always requires a system call on Unix but only requires one for symbolic links on Windows.

To add the contents of mydirectory to a new zip file, including all files and subdirectories:

import os
import zipfile

zf = zipfile.ZipFile("myzipfile.zip", "w")
for dirname, subdirs, files in os.walk("mydirectory"):
    zf.write(dirname)
    for filename in files:
        zf.write(os.path.join(dirname, filename))
zf.close()

You could try to create your own color palette using the RColorBrewer package

my_palette <- colorRampPalette(c("green", "black", "red"))(n = 1000)

and see how this looks like. But I assume in your case only scaling would help if you really want to keep the black in "the middle". You can simply use my_palette instead of the redgreen()

I recommend that you check out the RColorBrewer package, they have pretty nice in-built palettes, and see interactive website for colorbrewer.

Someone should mention that in the question there is a little trap. #ifdef will only check if the following symbol has been defined via #define or by command line, but its value (its substitution in fact) is irrelevant. You could even write

#define one

precompilers accept that. But if you use #if it's another thing.

#define one 0
#if one
    printf("one evaluates to a truth ");
#endif
#if !one
    printf("one does not evaluate to truth ");
#endif

will give one does not evaluate to truth. The keyword defined allows to get the desired behaviour.

#if defined(one) 

is therefore equivalent to #ifdef

The advantage of the #if construct is to allow a better handling of code paths, try to do something like that with the old #ifdef/#ifndef pair.

#if defined(ORA_PROC) || defined(__GNUC) && __GNUC_VERSION > 300

As long as we're doing creative answers, here is another one.

Use the external sort program to sort the input file numerically. This will work for any amount of memory you may have (it will use file storage if needed). Read through the sorted file and output the first number that is missing.

This will print everything after each match, on that same line only:

perl -lne 'print $1 if /^potato:\s*(.*)/' file.txt

This will do the same, except it will also print all subsequent lines:

perl -lne 'if ($found){print} elsif (/^potato:\s*(.*)/){print $1; $found++}' file.txt

These command-line options are used:

• -n loop around each line of the input file
• -l removes newlines before processing, and adds them back in afterwards
• -e execute the perl code

I used answers from above and added formatting

public final class DebugUtil {

    private static final String SEPARATOR = "\n";

    private DebugUtil() {
    }

    public static String formatStackTrace(StackTraceElement[] stackTrace) {
        StringBuilder buffer = new StringBuilder();
        for (StackTraceElement element : stackTrace) {
            buffer.append(element).append(SEPARATOR);
        }
        return buffer.toString();
    }

    public static String formatCurrentStacktrace() {
        StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
        return formatStackTrace(stackTrace);
    }
}

This 'just works' for me using jQuery, provided you don't try to append a subset the XHR-returned HTML to the document. (See this bug report showing the problem with jQuery.)

Here is an example showing it working:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> 
<html lang="en"> 
<head> 
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 
    <title>test_1.4</title> 
    <script type="text/javascript" charset="utf-8" src="jquery.1.4.2.js"></script> 
    <script type="text/javascript" charset="utf-8"> 
        var snippet = "<div><span id='a'>JS did not run<\/span><script type='text/javascript'>" +
        "$('#a').html('Hooray! JS ran!');" +
        "<\/script><\/div>";
        $(function(){
            $('#replaceable').replaceWith($(snippet));
        });
    </script> 
</head> 
<body> 
    <div id="replaceable">I'm going away.</div> 
</body> 
</html>

Here is the equivalent of the above: http://jsfiddle.net/2CTLH/

If you have vectors destined to become rows, concatenate them using c(), pass them to a matrix row-by-row, and convert that matrix to a dataframe.

For example, rows

dummydata1=c(2002,10,1,12.00,101,426340.0,4411238.0,3598.0,0.92,57.77,4.80,238.29,-9.9)
dummydata2=c(2002,10,2,12.00,101,426340.0,4411238.0,3598.0,-3.02,78.77,-9999.00,-99.0,-9.9)
dummydata3=c(2002,10,8,12.00,101,426340.0,4411238.0,3598.0,-5.02,88.77,-9999.00,-99.0,-9.9)

can be converted to a data frame thus:

dummyset=c(dummydata1,dummydata2,dummydata3)
col.len=length(dummydata1)
dummytable=data.frame(matrix(data=dummyset,ncol=col.len,byrow=TRUE))

Admittedly, I see 2 major limitations: (1) this only works with single-mode data, and (2) you must know your final # columns for this to work (i.e., I'm assuming that you're not working with a ragged array whose greatest row length is unknown a priori).

This solution seems simple, but from my experience with type conversions in R, I'm sure it creates new challenges down-the-line. Can anyone comment on this?

You can also use this:

private boolean doesUserHavePermission()
{
    int result = context.checkCallingOrSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE);
    return result == PackageManager.PERMISSION_GRANTED;
}

You can also use

$('#myModal').hasClass('show');

The suggestions from stb and xiowl are fine if you're looking for a constant. If you need to use existing fields or parameters which are integers, you can cast them to be floats first:

SELECT CAST(1 AS float) / CAST(3 AS float)

or

SELECT CAST(MyIntField1 AS float) / CAST(MyIntField2 AS float)

your syntax is wrong:

update mytable SET title = TRIM(TRAILING '\n' FROM title)

Addition:

If the newline character is at the start of the field:

update mytable SET title = TRIM(LEADING '\n' FROM title)

My bad, in trying to simplify it, I went too far, actually stuffs is a record of all kinds of info, I just want the id in it.

stuffs = [[123, first, last], [456, first, last]]

I want my_sting to be

my_sting = '123, 456'

My original code should have looked like this:

{% set my_string = '' %}
{% for stuff in stuffs %}
{% set my_string = my_string + stuff.id + ', '%}
{% endfor%}

Thinking about it, stuffs is probably a dictionary, but you get the gist.

Yes I found the join filter, and was going to approach it like this:

 {% set my_string = [] %}
 {% for stuff in stuffs %}
 {% do my_string.append(stuff.id) %}
 {% endfor%}
 {%  my_string|join(', ') %}

But the append doesn't work without importing the extensions to do it, and reading that documentation gave me a headache. It doesn't explicitly say where to import it from or even where you would put the import statement, so I figured finding a way to concat would be the lesser of the two evils.

This should do the trick for ASP.NET. The concept is the same as shown in the PHP example. Since the URL is different everytime the script is loaded, neither browser of proxy should cache the file. I'm used to put my JavaScript code into separate files, and wasted a significant amount of time with Visual Studio until I realized that it wouldn't reload the JavaScript files.

<script src="Scripts/main.js?version=<% =DateTime.Now.Ticks.ToString()%>" type="text/javascript"></script>

Full example:

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
    CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>

<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">

   <script src="Scripts/jquery-1.4.1-vsdoc.js" type="text/javascript"></script>  
   <script src="Scripts/main.js?version=<% =DateTime.Now.Ticks.ToString()%>" type="text/javascript"></script>
    <script type="text/javascript">

        $(document).ready(function () {
                                myInit();
                          });

    </script>
</asp:Content>

Obvously, this solution should only be used during the development stage, and should be removed before posting the site.

I understand that the mkdir operation is atomic, so you could create a lock directory

#!/bin/sh
lockdir=/tmp/AXgqg0lsoeykp9L9NZjIuaqvu7ANILL4foeqzpJcTs3YkwtiJ0
mkdir $lockdir  || {
    echo "lock directory exists. exiting"
    exit 1
}
# take pains to remove lock directory when script terminates
trap "rmdir $lockdir" EXIT INT KILL TERM

# rest of script here

struct node{
    int position;
    char name[30];
    struct node * next;
};

void free_list(node * list){
    node* next_node;

    printf("\n\n Freeing List: \n");
    while(list != NULL)
    {
        next_node = list->next;
        printf("clear mem for: %s",list->name);
        free(list);
        list = next_node;
        printf("->");
    }
}

It prints true on my machine. And it should, otherwise nothing in Java would work as expected. (This is explained in the JLS: 4.3.4 When Reference Types Are the Same)

Do you have multiple classloaders in place?

Ah, and in response to this comment:

I realise I have a typo in my question. I should be like this:

MyImplementedObject obj = new MyImplementedObject ();
if(obj.getClass() == MyObjectInterface.class) System.out.println("true");

MyImplementedObject implements MyObjectInterface So in other words, I am comparing it with its implemented objects.

OK, if you want to check that you can do either:

if(MyObjectInterface.class.isAssignableFrom(obj.getClass()))

or the much more concise

if(obj instanceof MyobjectInterface)

I'm trying to understand super()

The reason we use super is so that child classes that may be using cooperative multiple inheritance will call the correct next parent class function in the Method Resolution Order (MRO).

In Python 3, we can call it like this:

class ChildB(Base):
    def __init__(self):
        super().__init__()

In Python 2, we were required to use it like this, but we'll avoid this here:

        super(ChildB, self).__init__()

Without super, you are limited in your ability to use multiple inheritance because you hard-wire the next parent's call:

        Base.__init__(self) # Avoid this.

I further explain below.

"What difference is there actually in this code?:"

class ChildA(Base):
    def __init__(self):
        Base.__init__(self)

class ChildB(Base):
    def __init__(self):
        super().__init__()

The primary difference in this code is that in ChildB you get a layer of indirection in the __init__ with super, which uses the class in which it is defined to determine the next class's __init__ to look up in the MRO.

I illustrate this difference in an answer at the canonical question, How to use 'super' in Python?, which demonstrates dependency injection and cooperative multiple inheritance.

If Python didn't have super

Here's code that's actually closely equivalent to super (how it's implemented in C, minus some checking and fallback behavior, and translated to Python):

class ChildB(Base):
    def __init__(self):
        mro = type(self).mro()
        check_next = mro.index(ChildB) + 1 # next after *this* class.
        while check_next < len(mro):
            next_class = mro[check_next]
            if '__init__' in next_class.__dict__:
                next_class.__init__(self)
                break
            check_next += 1

Written a little more like native Python:

class ChildB(Base):
    def __init__(self):
        mro = type(self).mro()
        for next_class in mro[mro.index(ChildB) + 1:]: # slice to end
            if hasattr(next_class, '__init__'):
                next_class.__init__(self)
                break

If we didn't have the super object, we'd have to write this manual code everywhere (or recreate it!) to ensure that we call the proper next method in the Method Resolution Order!

How does super do this in Python 3 without being told explicitly which class and instance from the method it was called from?

It gets the calling stack frame, and finds the class (implicitly stored as a local free variable, __class__, making the calling function a closure over the class) and the first argument to that function, which should be the instance or class that informs it which Method Resolution Order (MRO) to use.

Since it requires that first argument for the MRO, using super with static methods is impossible as they do not have access to the MRO of the class from which they are called.

Criticisms of other answers:

super() lets you avoid referring to the base class explicitly, which can be nice. . But the main advantage comes with multiple inheritance, where all sorts of fun stuff can happen. See the standard docs on super if you haven't already.

It's rather hand-wavey and doesn't tell us much, but the point of super is not to avoid writing the parent class. The point is to ensure that the next method in line in the method resolution order (MRO) is called. This becomes important in multiple inheritance.

I'll explain here.

class Base(object):
    def __init__(self):
        print("Base init'ed")

class ChildA(Base):
    def __init__(self):
        print("ChildA init'ed")
        Base.__init__(self)

class ChildB(Base):
    def __init__(self):
        print("ChildB init'ed")
        super().__init__()

And let's create a dependency that we want to be called after the Child:

class UserDependency(Base):
    def __init__(self):
        print("UserDependency init'ed")
        super().__init__()

Now remember, ChildB uses super, ChildA does not:

class UserA(ChildA, UserDependency):
    def __init__(self):
        print("UserA init'ed")
        super().__init__()

class UserB(ChildB, UserDependency):
    def __init__(self):
        print("UserB init'ed")
        super().__init__()

And UserA does not call the UserDependency method:

>>> UserA()
UserA init'ed
ChildA init'ed
Base init'ed
<__main__.UserA object at 0x0000000003403BA8>

But UserB does in-fact call UserDependency because ChildB invokes super:

>>> UserB()
UserB init'ed
ChildB init'ed
UserDependency init'ed
Base init'ed
<__main__.UserB object at 0x0000000003403438>

Criticism for another answer

In no circumstance should you do the following, which another answer suggests, as you'll definitely get errors when you subclass ChildB:

super(self.__class__, self).__init__()  # DON'T DO THIS! EVER.

_{(That answer is not clever or particularly interesting, but in spite of direct criticism in the comments and over 17 downvotes, the answerer persisted in suggesting it until a kind editor fixed his problem.)}

Explanation: Using self.__class__ as a substitute for the class name in super() will lead to recursion. super lets us look up the next parent in the MRO (see the first section of this answer) for child classes. If you tell super we're in the child instance's method, it will then lookup the next method in line (probably this one) resulting in recursion, probably causing a logical failure (in the answerer's example, it does) or a RuntimeError when the recursion depth is exceeded.

>>> class Polygon(object):
...     def __init__(self, id):
...         self.id = id
...
>>> class Rectangle(Polygon):
...     def __init__(self, id, width, height):
...         super(self.__class__, self).__init__(id)
...         self.shape = (width, height)
...
>>> class Square(Rectangle):
...     pass
...
>>> Square('a', 10, 10)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in __init__
TypeError: __init__() missing 2 required positional arguments: 'width' and 'height'

Python 3's new super() calling method with no arguments fortunately allows us to sidestep this issue.

No there isn't. Instead use a while loop such as:

while 1:
 ...statements...
  if cond:
    break

In my current project the solution looks like this:

I created an abstract Language State

$stateProvider.state('language', {
    abstract: true,
    url: '/:language',
    template: '<div ui-view class="lang-{{language}}"></div>'
});

Every state in the project has to depend on this state

$stateProvider.state('language.dashboard', {
    url: '/dashboard'
    //....
});

The language switch buttons calls a custom function:

<a ng-click="footer.setLanguage('de')">de</a>

And the corresponding function looks like this (inside a controller of course):

this.setLanguage = function(lang) {
    FooterLog.log('switch to language', lang);
    $state.go($state.current, { language: lang }, {
        location: true,
        reload: true,
        inherit: true
    }).then(function() {
        FooterLog.log('transition successfull');
    });
};

This works, but there is a nicer solution just changing a value in the state params from html:

<a ui-sref="{ language: 'de' }">de</a>

Unfortunately this does not work, see https://github.com/angular-ui/ui-router/issues/1031

static void Main(string[] args)
{
    foreach (int value in Enum.GetValues(typeof(DaysOfWeek)))
    {
        Console.WriteLine(((DaysOfWeek)value).ToString());
    }

    foreach (string value in Enum.GetNames(typeof(DaysOfWeek)))
    {
        Console.WriteLine(value);
    }
    Console.ReadLine();
}

public enum DaysOfWeek
{
    monday,
    tuesday,
    wednesday
}

In Windows Forms:

this.StartPosition = FormStartPosition.CenterScreen;

In WPF:

In MS-DOS COMMAND.COM shell, you have to use:

d:

cd \windows\movie

If by chance you actually meant "Windows command prompt" (which is not MS-DOS and not DOS at all), then you can use cd /d d:\windows\movie.

for simple setups, you can provide ssh access to a central server, and set up each user's working directory to push/pull from this 'origin'. That would be the most simple and common setup for small teams.

You might also look into gitosis which gives you an http server and the ability to manage it remotely. That way you don't have to grant ssh access and all that entails to each committer.

Update

• You can use getString(R.string.some_string_id) in both Activity or Fragment.
• You can use Context.getString(R.string.some_string_id) where you don't have direct access to getString() method. Like Dialog.

Problem is where you don't have Context access, like a method in your Util class.

Assume below method without Context.

public void someMethod(){
    ...
    // can't use getResource() or getString() without Context.
}

Now you will pass Context as a parameter in this method and use getString().

public void someMethod(Context context){
    ...
    context.getString(R.string.some_id);
}

What i do is

public void someMethod(){
    ...
    App.getRes().getString(R.string.some_id)
}

What? It is very simple to use anywhere in your app!

So here is a Bonus unique solution by which you can access resources from anywhere like Util class .

import android.app.Application;
import android.content.res.Resources;

public class App extends Application {
    private static App mInstance;
    private static Resources res;


    @Override
    public void onCreate() {
        super.onCreate();
        mInstance = this;
        res = getResources();
    }

    public static App getInstance() {
        return mInstance;
    }

    public static Resources getResourses() {
        return res;
    }

}

Add name field to your manifest.xml <application tag.

<application
        android:name=".App"
        ...
        >
        ...
    </application>

Now you are good to go.

Set the value from code on showing the form, not in the design-timeProperties for the text box.

Private Sub UserForm_Activate()
    Me.txtDate.Value = Format(Date, "mm/dd/yy")
End Sub

The short answer is that you can't do it using JavaScript alone. You'd need a server-side handler to connect with the SMTP server to actually send the mail. There are many simple mail scripts online, such as this one for PHP:

Simple PHP mail script

Using a script like that, you'd POST the contents of your web form to the script, using a function like this:

jQuery.post

And then the script would take those values, plus a username and password for the mail server, and connect to the server to send the mail.

For generating the KML file from your CSV file (or XLS), you can use MyGeodata online GIS Data Converter. Here is the CSV to KML How-To.

To define this on a permanent basis for the current user, create (or edit) the .vimrc file:

$ vim ~/.vimrc

Then, paste the configuration below into the file. Once vim is restarted, the tab settings will apply.

set tabstop=4       " The width of a TAB is set to 4.
                    " Still it is a \t. It is just that
                    " Vim will interpret it to be having
                    " a width of 4.

set shiftwidth=4    " Indents will have a width of 4

set softtabstop=4   " Sets the number of columns for a TAB

set expandtab       " Expand TABs to spaces

If, like me, you are doing this for a column which then goes through COALESCE / array_to_json / ARRAY_AGG / row_to_json (PostgreSQL) and want to keep the capitals in the column name, double quote the column name, like so:

SELECT a.price AS "myFirstPrice", b.price AS "mySecondPrice"

Without the quotes (and when using those functions), my column names in camelCase would lose the capital letters.

Putting this here for future reference. I'm in the midst of an email migration. I need to know each user account and its respective group membership, and also I need to know each group and its respective members.

I'm using the code block below to output a CSV for each user's group membership.

Get-ADUser -Filter * |`
  ForEach-Object { `
    $FileName = $_.SamAccountName + ".csv" ; `
    $FileName ; `
    Get-ADPrincipalGroupMembership $_ | `
      Select-Object -Property SamAccountName, name, GroupScope, GroupCategory | `
        Sort-Object -Property SamAccountName | `
          Export-Csv -Path $FileName -Encoding ASCII ; `
  }

The export process for the groups and their respective members was a little convoluted, but the below works. The output filenames include the type of group. Therefore, the email distribution groups I need are/should be the Universal and Global Distribution groups. I should be able to just delete or move the resulting TXT files I don't need.

Get-ADGroup -Filter * | `
 Select-Object -Property Name, DistinguishedName, GroupScope, GroupCategory | `
  Sort-Object -Property GroupScope, GroupCategory, Name | `
   Export-Csv -Path ADGroupsNew.csv -Encoding ASCII

$MyCSV = Import-Csv -Path .\ADGroupsNew.csv -Encoding ASCII

$MyCSV | `
 ForEach-Object { `
  $FN = $_.GroupScope + ", " + $_.GroupCategory + ", " + $_.Name + ".txt" ; `
  $FN ; `
  Get-ADGroupMember -Identity $_.DistinguishedName | `
   Out-File -FilePath $FN -Encoding ASCII ; $FN=""; `
  }

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

I found that following these instructions helped with finding what the problem was. For me, that was the killer, not knowing what was broken.

http://mythinkpond.wordpress.com/2011/07/01/tomcat-6-infamous-severe-error-listenerstart-message-how-to-debug-this-error/

Quoting from the link

In Tomcat 6 or above, the default logger is the”java.util.logging” logger and not Log4J. So if you are trying to add a “log4j.properties” file – this will NOT work. The Java utils logger looks for a file called “logging.properties” as stated here: http://tomcat.apache.org/tomcat-6.0-doc/logging.html

So to get to the debugging details create a “logging.properties” file under your”/WEB-INF/classes” folder of your WAR and you’re all set.

And now when you restart your Tomcat, you will see all of your debugging in it’s full glory!!!

Sample logging.properties file:

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

The answer provided by Joe Stefanelli is already correct.

SELECT name FROM (SELECT name FROM agentinformation) as a  

We need to make an alias of the subquery because a query needs a table object which we will get from making an alias for the subquery. Conceptually, the subquery results are substituted into the outer query. As we need a table object in the outer query, we need to make an alias of the inner query.

Statements that include a subquery usually take one of these forms:

• WHERE expression [NOT] IN (subquery)
• WHERE expression comparison_operator [ANY | ALL] (subquery)
• WHERE [NOT] EXISTS (subquery)

Check for more subquery rules and subquery types.

More examples of Nested Subqueries.

1. IN / NOT IN – This operator takes the output of the inner query after the inner query gets executed which can be zero or more values and sends it to the outer query. The outer query then fetches all the matching [IN operator] or non matching [NOT IN operator] rows.

2. ANY – [>ANY or ANY operator takes the list of values produced by the inner query and fetches all the values which are greater than the minimum value of the list. The

e.g. >ANY(100,200,300), the ANY operator will fetch all the values greater than 100.

3. ALL – [>ALL or ALL operator takes the list of values produced by the inner query and fetches all the values which are greater than the maximum of the list. The

e.g. >ALL(100,200,300), the ALL operator will fetch all the values greater than 300.

4. EXISTS – The EXISTS keyword produces a Boolean value [TRUE/FALSE]. This EXISTS checks the existence of the rows returned by the sub query.

You can also use any(), map() like so:

if any(map(l.startswith, x)):
    pass # Do something

Or alternatively, using a generator expression:

if any(l.startswith(s) for s in x)
    pass # Do something

There's a trick you can do with the pre-processor.
It has the potential down sides that it will collapse white-space, and could be confusing for people reading the code.
But, it has the up side that you don't need to escape quote characters inside it.

#define QUOTE(...) #__VA_ARGS__
const char *sql_query = QUOTE(
    SELECT word_id
    FROM table1, table2
    WHERE table2.word_id = table1.word_id
    ORDER BY table1.word ASC
);

the preprocessor turns this into:

const char *sql_query = "SELECT word_id FROM table1, table2 WHERE table2.word_id = table1.word_id ORDER BY table1.word ASC";

I've used this trick when I was writing some unit tests that had large literal strings containing JSON. It meant that I didn't have to escape every quote character \".

Solution in python can be as below:

class Word:
    def __init__(self, data, index):
        self.data = data
        self.index = index

def printAnagrams(arr):
    dupArray = []
    size = len(arr)

    for i in range(size):
        dupArray.append(Word(arr[i], i))

    for i in range(size):
        dupArray[i].data = ''.join(sorted(dupArray[i].data))

    dupArray = sorted(dupArray, key=lambda x: x.data)

    for i in range(size):
        print arr[dupArray[i].index]

def main():
    arr = ["dog", "act", "cat", "god", "tac"]

    printAnagrams(arr)

if __name__== '__main__':
    main()

1. First create a duplicate list of same words with indexes representing their position indexes.
2. Then sort the individual strings of the duplicate list
3. Then sort the duplicate list itself based on strings.
4. Finally print the original list with indexes used from duplicate array.

The time complexity of above is O(NMLogN + NMLogM) = O(NMlogN)

To calculate a z-score for an entire column quickly, do as follows:

from scipy.stats import zscore
import pandas as pd

df = pd.DataFrame({'num_1': [1,2,3,4,5,6,7,8,9,3,4,6,5,7,3,2,9]})
df['num_1_zscore'] = zscore(df['num_1'])

display(df)

If you dont have an entry point defined in your manifest invoking java -jar foo.jar will not work.

Use this command if you dont have a manifest or to run a different main class than the one specified in the manifest:

java -cp foo.jar full.package.name.ClassName

See also instructions on how to create a manifest with an entry point: https://docs.oracle.com/javase/tutorial/deployment/jar/appman.html

Add this to the stylesheet:

table {
  border-collapse: collapse;
}

JSFiddle.

The reason why it behaves this way is actually described pretty well in the specification:

There are two distinct models for setting borders on table cells in CSS. One is most suitable for so-called separated borders around individual cells, the other is suitable for borders that are continuous from one end of the table to the other.

... and later, for collapse setting:

In the collapsing border model, it is possible to specify borders that surround all or part of a cell, row, row group, column, and column group.

There are two obvious points, as well as the points in the other answer:

• They are exactly equivalent when using sub queries:

  SELECT * FROM table
  WHERE column IN(subquery);
  
  SELECT * FROM table
  WHERE column = ANY(subquery);
  

On the other hand:

• Only the IN operator allows a simple list:

  SELECT * FROM table
  WHERE column IN(… , … , …);
  

Presuming they are exactly the same has caught me out several times when forgetting that ANY doesn’t work with lists.

Not sure what kind of text box you are refering to. However, I'm not sure if you can do this in a text box on a user form.

A text box on a sheet you can though.

Sheets("Sheet1").Shapes("TextBox 1").TextFrame2.TextRange.Text = "R2=" & variable
Sheets("Sheet1").Shapes("TextBox 1").TextFrame2.TextRange.Characters(2, 1).Font.Superscript = msoTrue

And same thing for an excel cell

Sheets("Sheet1").Range("A1").Characters(2, 1).Font.Superscript = True

If this isn't what you're after you will need to provide more information in your question.

EDIT: posted this after the comment sorry

They're the same, aren't they? Now I'm losing confidence in myself but I really thought IPv6 was just an addressing change. TCP and UDP are still addressed as they are under IPv4.

do a :

git branch

if git show you something like :

* (no branch)
master
Dbranch

You have a "detached HEAD". If you have modify some files on this branch you, commit them, then return to master with

git checkout master 

Now you should be able to delete the Dbranch.

Compose an email in the phone email client:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("plain/text");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { "[email protected]" });
intent.putExtra(Intent.EXTRA_SUBJECT, "subject");
intent.putExtra(Intent.EXTRA_TEXT, "mail body");
startActivity(Intent.createChooser(intent, ""));

the class attribute contains disabled when the element is not clickable.

WebElement webElement = driver.findElement(By.id("elementId"));
if(!webElement.getAttribute("class").contains("disabled")){
    webElement.click();
}

Simply put:

.democlass {
    background-color: rgba(246,245,245,0);
}

That should give you a transparent background.

Using req.session = null;, won't actually delete the session instance. The most proper solution would be req.session.destroy();, but this is essentially a wrapper for delete req.session;.

Session.prototype.destroy = function(fn){
  delete this.req.session;
  this.req.sessionStore.destroy(this.id, fn);

PEP 8 advises the first form for readability. You can find it here.

Function names should be lowercase, with words separated by underscores as necessary to improve readability.

In case your git-bash's PATH presents but not latest and you don't want a reboot but regenerate your PATHs, you can try the following:

• Close all cmd.exe, powershell.exe, and git-bash.exe and reopen one cmd.exe window from the Start Menu or Desktop context.
• If you changed system-wide PATH, you may also need to open one privileged cmd window.
• Open Git bash from Windows Explorer context menu and see if the PATH env is updated. Please note that the terminal in IntelliJ IDEA is probably a login shell or some other kind of magic, so PATH in it may won't change until you restart IDEA.
• If that does not work, you may need to close all Windows Explorer process as well and retry the steps above.

Note: This doesn't work with all Windows versions, and open cmd.exe anywhere other than the Start Menu or Desktop context menu may not work, tested with my 4 computers and 3 of them works. I didn't figure out why this works, but since the PATH environment variable is generated automatically when I login and logout, I'd not to mess up that variable with variable concatenation.

According to Android's documentation, you should also often include screenSize as a possible configuration change.

android:configChanges="orientation|screenSize"

If your application targets API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), then you should also declare the "screenSize" configuration, because it also changes when a device switches between portrait and landscape orientations.

Also, if you all include value keyboardHidden in your examples, shouldn't you then also consider locale, mcc, fontScale, keyboard and others?..

The accepted answer here does not mention a fact that if you have a null string ToLower() will throw an exception. The safer way would be to do:

fi => (fi.DESCRIPTION ?? string.Empty).ToLower().Contains((description ?? string.Empty).ToLower())

It only works in combination with the display  property set to <b>-webkit-box</b> or <b>-webkit-inline-box</b> and the <b>-webkit-box-orient</b> property set to vertical. In most cases you will also want to set overflow to hidden, otherwise the contents won't be clipped but an ellipsis will still be shown after the specified number of lines. When applied to anchor elements, the truncating can happen in the middle of the text, not necessarily at the end.
</div>

or

public String getFileStream(final String inputFile) {
        String result = "";
        Scanner s = null;

        try {
            s = new Scanner(new BufferedReader(new FileReader(inputFile)));
            while (s.hasNext()) {
                result = result + s.nextLine();
            }
        } catch (final IOException ex) {
            ex.printStackTrace();
        } finally {
            if (s != null) {
                s.close();
            }
        }
        return result;
}

This gets first line as well.

With that code you load the file in memory (as a big string) and then you read that string line by line.

By using Mid$() and InStr() you actually read the "file" twice but since it's in memory, there is no problem.
I don't know if VB's String has a length limit (probably not) but if the text files are hundreds of megabyte in size it's likely to see a performance drop, due to virtual memory usage.

The error is from this:

def playSound(myList):
  for i in range(myList): # <= myList is a list, not an integer

You cannot pass a list to range which expects an integer. Most likely, you meant to do:

 def playSound(myList):
  for list_item in myList:

OR

 def playSound(myList):
  for i in range(len(myList)):

OR

 def playSound(myList):
  for i, list_item in enumerate(myList):

I have Done the Following Things in IIS 8.5 (Windows Server 2012 R2)Server and its Worked in My Case Without Restart:

1. Selecting The Application Pool That Connected to The Application in IIS
   

2. And Right Click --> Advanced Settings --> Process Model --> Select Local System Instead of Recommended ApplicationPoolIdentity
   

3. And Make Sure C:\Windows\SysWOW64\config\systemprofile\desktop Have Enough Access For Users.
   

4. Refresh the Website Link that Connected With this Pool

Also consider using Array(). From the Ruby Community Style Guide:

Use Array() instead of explicit Array check or [*var], when dealing with a variable you want to treat as an Array, but you're not certain it's an array.

# bad
paths = [paths] unless paths.is_a? Array
paths.each { |path| do_something(path) }

# bad (always creates a new Array instance)
[*paths].each { |path| do_something(path) }

# good (and a bit more readable)
Array(paths).each { |path| do_something(path) }

There is not a program but you can make a batch file and run a command like that :

powershell "start-process 'C:\Program Files (x86)\IIS Express\iisexpress.exe' -workingdirectory 'C:\Program Files (x86)\IIS Express\' -windowstyle Hidden"

I believe you can accomplish it by just having single ng-view. In the main template you can have ng-include sections for sub views, then in the main controller define model properties for each sub template. So that they will bind automatically to ng-include sections. This is same as having multiple ng-view

You can check the example given in ng-include documentation

in the example when you change the template from dropdown list it changes the content. Here assume you have one main ng-view and instead of manually selecting sub content by selecting drop down, you do it as when main view is loaded.

"Egg" is a single-file importable distribution format for Python-related projects.

"The Quick Guide to Python Eggs" notes that "Eggs are to Pythons as Jars are to Java..."

Eggs actually are richer than jars; they hold interesting metadata such as licensing details, release dependencies, etc.

You can try the following:

First, add async defer. This specifies that the script will be executed asynchronously as soon as it is available and when the page has finished parsing.

Second, add the initMap() function as a callback in a script tag inside your html. In this way the map will be initialized before the document.ready and window.onload:

<script async defer src="{{ 'https://maps.googleapis.com/maps/api/js?key=$key&language='.$language.'&region='.$country.'&callback=initMap' }}"></script>

<script>
    var map;
    function initMap() {
        map = new google.maps.Map(document.getElementById('map'), {
            center: {lat: -34.397, lng: 150.644},
            zoom: 4,
            disableDefaultUI: false,
            scrollwheel: false,
            styles: [{ ... }]
        });
    }
</script> 

Finally, you can use the map object inside your js files.

Please check this:

$servername='localhost';
$username='root';
$password='';
$databasename='MyDb';

$connection = mysqli_connect($servername,$username,$password);

if (!$connection) {
die("Connection failed: " . $conn->connect_error);
}

/*mysqli_query($connection, "DROP DATABASE if exists MyDb;");

if(!mysqli_query($connection, "CREATE DATABASE MyDb;")){
echo "Error creating database: " . $connection->error;
}

mysqli_query($connection, "use MyDb;");
mysqli_query($connection, "DROP TABLE if exists employee;");

$table="CREATE TABLE employee (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
reg_date TIMESTAMP
)"; 
$value="INSERT INTO employee (firstname,lastname,email) VALUES ('john', 'steve', '[email protected]')";
if(!mysqli_query($connection, $table)){echo "Error creating table: " . $connection->error;}
if(!mysqli_query($connection, $value)){echo "Error inserting values: " . $connection->error;}*/

If you use MVC, tables, it works like this:

<td>@(((DateTime)detalle.fec).ToString("dd'/'MM'/'yyyy"))</td>

I'm also a stranger to windows cmd, but try this:

Use the CheckBoxList's GetItemChecked or GetItemCheckState method to find out whether an item is checked or not by its index.

Another option to fine-tune the line height of an icon is by using a percentage of the vertical-align property. Usually, 0% is a the bottom, and 100% at the top, but one could use negative values or more than a hundred to create interesting effects.

.my-element i.fa {
    vertical-align: 100%; // top
    vertical-align: 50%; // middle
    vertical-align: 0%; // bottom
}

Can you provide some more details like which linux you are using? Are you loged in as root? On linux you have to run export CLASSPATH = %path%;LOG4J_HOME/og4j-1.2.16.jar If you want it permanent then you can add above lines in ~/.bashrc file.

The Java Generics FAQ and therefore also cletus' answer sound like there is no point in having Class<List<T>>, however the real problem is that this is extremely dangerous:

@SuppressWarnings("unchecked")
Class<List<String>> stringListClass = (Class<List<String>>) (Class<?>) List.class;

List<Integer> intList = new ArrayList<>();
intList.add(1);
List<String> stringList = stringListClass.cast(intList);
// Surprise!
String firstElement = stringList.get(0);

The cast() makes it look as if it is safe, but in reality it is not safe at all.

Though I don't get where there can't be List<?>.class = Class<List<?>> since this would be pretty helpful when you have a method which determines the type based on the generic type of a Class argument.

For getClass() there is JDK-6184881 requesting to switch to using wildcards, however it does not look like this change will be performed (very soon) since it is not compatible with previous code (see this comment).

From http://developer.android.com/guide/components/processes-and-threads.html :

Additionally, the Android UI toolkit is not thread-safe. So, you must not manipulate your UI from a worker thread—you must do all manipulation to your user interface from the UI thread. Thus, there are simply two rules to Android's single thread model:

1. Do not block the UI thread
2. Do not access the Android UI toolkit from outside the UI thread

You have to detect idleness in a worker thread and show a toast in the main thread.

Please post some code, if you want a more detailed answer.

After code publication :

In strings.xml

<string name="idleness_toast">"You are getting late do it fast"</string>

In YourWorkerThread.java

Toast.makeText(getApplicationContext(), getString(R.string.idleness_toast), 
    Toast.LENGTH_LONG).show();

Don't use AlertDialog, make a choice. AlertDialog and Toast are two different things.

since npm 5.2.0, there's a new command "npx" included with npm that makes this much simpler, if you run:

npx mocha <args>

Note: the optional args are forwarded to the command being executed (mocha in this case)

this will automatically pick the executable "mocha" command from your locally installed mocha (always add it as a dev dependency to ensure the correct one is always used by you and everyone else).

Be careful though that if you didn't install mocha, this command will automatically fetch and use latest version, which is great for some tools (like scaffolders for example), but might not be the most recommendable for certain dependencies where you might want to pin to a specific version.

You can read more on npx here

Now, if instead of invoking mocha directly, you want to define a custom npm script, an alias that might invoke other npm binaries...

you don't want your library tests to fail depending on the machine setup (mocha as global, global mocha version, etc), the way to use the local mocha that works cross-platform is:

node node_modules/.bin/mocha

npm puts aliases to all the binaries in your dependencies on that special folder. Finally, npm will add node_modules/.bin to the PATH automatically when running an npm script, so in your package.json you can do just:

"scripts": {
  "test": "mocha"
}

and invoke it with

npm test

I was getting this error because I misread the accepted answer from here: Create Windows service from executable.

sc.exe create <new_service_name> binPath= "<path_to_the_service_executable>"

For <path_to_service_executable>, I was using the path of the executable's folder, e.g. C:\Folder.

It needs to be the path of the executable, e.g. C:\Folder\Executable.exe.

$("#btnAddProfile").click(function(){
    $("#btnAddProfile").attr('value', 'Save');
 });

dataGridView1[row, col].Style.BackColor = System.Drawing.Color.Red;

Perhaps something like this for the first problem, you can simply access the columns by their names:

>>> df = pd.DataFrame(np.random.rand(4,5), columns = list('abcde'))
>>> df[df['c']>.5][['b','e']]
          b         e
1  0.071146  0.132145
2  0.495152  0.420219

For the second problem:

>>> df[df['c']>.5][['b','e']].values
array([[ 0.07114556,  0.13214495],
       [ 0.49515157,  0.42021946]])

You can't use a LinearLayout for this, but you can use a FrameLayout. In a FrameLayout, the z-index is defined by the order in which the items are added, for example:

<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >
    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/my_drawable"
        android:scaleType="fitCenter"
        />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|center"
        android:padding="5dp"
        android:text="My Label"
        />
</FrameLayout>

In this instance, the TextView would be drawn on top of the ImageView, along the bottom center of the image.

SHA stands for Secure Hash Algorithm while AES stands for Advanced Encryption Standard. So SHA is a suite of hashing algorithms. AES on the other hand is a cipher which is used to encrypt. SHA algorithms (SHA-1, SHA-256 etc...) will take an input and produce a digest (hash), this is typically used in a digital signing process (produce a hash of some bytes and sign with a private key).

Data-Binding

You go around making your webpage, and keep on putting {{data bindings}} whenever you feel you would have dynamic data. Angular will then provide you a $scope handler, which you can populate (statically or through calls to the web server).

This is a good understanding of data-binding. I think you've got that down.

DOM Manipulation

For simple DOM manipulation, which doesnot involve data manipulation (eg: color changes on mousehover, hiding/showing elements on click), jQuery or old-school js is sufficient and cleaner. This assumes that the model in angular's mvc is anything that reflects data on the page, and hence, css properties like color, display/hide, etc changes dont affect the model.

I can see your point here about "simple" DOM manipulation being cleaner, but only rarely and it would have to be really "simple". I think DOM manipulation is one the areas, just like data-binding, where Angular really shines. Understanding this will also help you see how Angular considers its views.

I'll start by comparing the Angular way with a vanilla js approach to DOM manipulation. Traditionally, we think of HTML as not "doing" anything and write it as such. So, inline js, like "onclick", etc are bad practice because they put the "doing" in the context of HTML, which doesn't "do". Angular flips that concept on its head. As you're writing your view, you think of HTML as being able to "do" lots of things. This capability is abstracted away in angular directives, but if they already exist or you have written them, you don't have to consider "how" it is done, you just use the power made available to you in this "augmented" HTML that angular allows you to use. This also means that ALL of your view logic is truly contained in the view, not in your javascript files. Again, the reasoning is that the directives written in your javascript files could be considered to be increasing the capability of HTML, so you let the DOM worry about manipulating itself (so to speak). I'll demonstrate with a simple example.

This is the markup we want to use. I gave it an intuitive name.

<div rotate-on-click="45"></div>

First, I'd just like to comment that if we've given our HTML this functionality via a custom Angular Directive, we're already done. That's a breath of fresh air. More on that in a moment.

Implementation with jQuery

live demo here (click).

function rotate(deg, elem) {
  $(elem).css({
    webkitTransform: 'rotate('+deg+'deg)', 
    mozTransform: 'rotate('+deg+'deg)', 
    msTransform: 'rotate('+deg+'deg)', 
    oTransform: 'rotate('+deg+'deg)', 
    transform: 'rotate('+deg+'deg)'    
  });
}

function addRotateOnClick($elems) {
  $elems.each(function(i, elem) {
    var deg = 0;
    $(elem).click(function() {
      deg+= parseInt($(this).attr('rotate-on-click'), 10);
      rotate(deg, this);
    });
  });
}

addRotateOnClick($('[rotate-on-click]'));

Implementation with Angular

live demo here (click).

app.directive('rotateOnClick', function() {
  return {
    restrict: 'A',
    link: function(scope, element, attrs) {
      var deg = 0;
      element.bind('click', function() {
        deg+= parseInt(attrs.rotateOnClick, 10);
        element.css({
          webkitTransform: 'rotate('+deg+'deg)', 
          mozTransform: 'rotate('+deg+'deg)', 
          msTransform: 'rotate('+deg+'deg)', 
          oTransform: 'rotate('+deg+'deg)', 
          transform: 'rotate('+deg+'deg)'    
        });
      });
    }
  };
});

Pretty light, VERY clean and that's just a simple manipulation! In my opinion, the angular approach wins in all regards, especially how the functionality is abstracted away and the dom manipulation is declared in the DOM. The functionality is hooked onto the element via an html attribute, so there is no need to query the DOM via a selector, and we've got two nice closures - one closure for the directive factory where variables are shared across all usages of the directive, and one closure for each usage of the directive in the link function (or compile function).

Two-way data binding and directives for DOM manipulation are only the start of what makes Angular awesome. Angular promotes all code being modular, reusable, and easily testable and also includes a single-page app routing system. It is important to note that jQuery is a library of commonly needed convenience/cross-browser methods, but Angular is a full featured framework for creating single page apps. The angular script actually includes its own "lite" version of jQuery so that some of the most essential methods are available. Therefore, you could argue that using Angular IS using jQuery (lightly), but Angular provides much more "magic" to help you in the process of creating apps.

This is a great post for more related information: How do I “think in AngularJS” if I have a jQuery background?

General differences.

The above points are aimed at the OP's specific concerns. I'll also give an overview of the other important differences. I suggest doing additional reading about each topic as well.

Angular and jQuery can't reasonably be compared.

Angular is a framework, jQuery is a library. Frameworks have their place and libraries have their place. However, there is no question that a good framework has more power in writing an application than a library. That's exactly the point of a framework. You're welcome to write your code in plain JS, or you can add in a library of common functions, or you can add a framework to drastically reduce the code you need to accomplish most things. Therefore, a more appropriate question is:

Why use a framework?

Good frameworks can help architect your code so that it is modular (therefore reusable), DRY, readable, performant and secure. jQuery is not a framework, so it doesn't help in these regards. We've all seen the typical walls of jQuery spaghetti code. This isn't jQuery's fault - it's the fault of developers that don't know how to architect code. However, if the devs did know how to architect code, they would end up writing some kind of minimal "framework" to provide the foundation (achitecture, etc) I discussed a moment ago, or they would add something in. For example, you might add RequireJS to act as part of your framework for writing good code.

Here are some things that modern frameworks are providing:

• Templating
• Data-binding
• routing (single page app)
• clean, modular, reusable architecture
• security
• additional functions/features for convenience

Before I further discuss Angular, I'd like to point out that Angular isn't the only one of its kind. Durandal, for example, is a framework built on top of jQuery, Knockout, and RequireJS. Again, jQuery cannot, by itself, provide what Knockout, RequireJS, and the whole framework built on top them can. It's just not comparable.

If you need to destroy a planet and you have a Death Star, use the Death star.

Angular (revisited).

Building on my previous points about what frameworks provide, I'd like to commend the way that Angular provides them and try to clarify why this is matter of factually superior to jQuery alone.

DOM reference.

In my above example, it is just absolutely unavoidable that jQuery has to hook onto the DOM in order to provide functionality. That means that the view (html) is concerned about functionality (because it is labeled with some kind of identifier - like "image slider") and JavaScript is concerned about providing that functionality. Angular eliminates that concept via abstraction. Properly written code with Angular means that the view is able to declare its own behavior. If I want to display a clock:

<clock></clock>

Done.

Yes, we need to go to JavaScript to make that mean something, but we're doing this in the opposite way of the jQuery approach. Our Angular directive (which is in it's own little world) has "augumented" the html and the html hooks the functionality into itself.

MVW Architecure / Modules / Dependency Injection

Angular gives you a straightforward way to structure your code. View things belong in the view (html), augmented view functionality belongs in directives, other logic (like ajax calls) and functions belong in services, and the connection of services and logic to the view belongs in controllers. There are some other angular components as well that help deal with configuration and modification of services, etc. Any functionality you create is automatically available anywhere you need it via the Injector subsystem which takes care of Dependency Injection throughout the application. When writing an application (module), I break it up into other reusable modules, each with their own reusable components, and then include them in the bigger project. Once you solve a problem with Angular, you've automatically solved it in a way that is useful and structured for reuse in the future and easily included in the next project. A HUGE bonus to all of this is that your code will be much easier to test.

It isn't easy to make things "work" in Angular.

THANK GOODNESS. The aforementioned jQuery spaghetti code resulted from a dev that made something "work" and then moved on. You can write bad Angular code, but it's much more difficult to do so, because Angular will fight you about it. This means that you have to take advantage (at least somewhat) to the clean architecture it provides. In other words, it's harder to write bad code with Angular, but more convenient to write clean code.

Angular is far from perfect. The web development world is always growing and changing and there are new and better ways being put forth to solve problems. Facebook's React and Flux, for example, have some great advantages over Angular, but come with their own drawbacks. Nothing's perfect, but Angular has been and is still awesome for now. Just as jQuery once helped the web world move forward, so has Angular, and so will many to come.

First of all, you should use none of them. You are using wrapper type, which should rarely be used in case you have a primitive type. So, you should use boolean rather.

Further, we initialize the boolean variable to false to hold an initial default value which is false. In case you have declared it as instance variable, it will automatically be initialized to false.

But, its completely upto you, whether you assign a default value or not. I rather prefer to initialize them at the time of declaration.

But if you are immediately assigning to your variable, then you can directly assign a value to it, without having to define a default value.

So, in your case I would use it like this: -

boolean isMatch = email1.equals (email2);

Use os.path.abspath():

os.chdir(os.path.dirname(os.path.abspath(sys.argv[0])))

sys.argv[0] in your case is just a script name, no directory, so os.path.dirname() returns an empty string.

os.path.abspath() turns that into a proper absolute path with directory name.

You may get ORA-01031: insufficient privileges instead of ORA-00942: table or view does not exist when you have at least one privilege on the table, but not the necessary privilege.

                console.log($variable);
            }
        });
    });

or

$(function() {
        $("#select-image").selectable({
            selected: function( event, ui ) { 
                var $variable = $('.ui-selected').val(); 
                console.log($variable);
            }
        });
    });

For Finding All the ChildNodes you can use the below Snippet

List<WebElement> childs = MyCurrentWebElement.findElements(By.xpath("./child::*"));

        for (WebElement e  : childs)
        {
            System.out.println(e.getTagName());
        }

Note that this will give all the Child Nodes at same level -> Like if you have structure like this :

<Html> 
<body> 
 <div> ---suppose this is current WebElement 
   <a>
   <a>
      <img>
          <a>
      <img>
   <a>

It will give me tag names of 3 anchor tags here only . If you want all the child Elements recursively , you can replace the above code with MyCurrentWebElement.findElements(By.xpath(".//*"));

Hope That Helps !!

I originally found this post looking for a solution to copying stored procedures from my remote production database to my local development database. After success using the suggested approach in this thread, I realized I grew increasingly lazy (or resourceful, whichever you prefer) and wanted this to be automated. I came across this link, which proved to be very helpful (thank you vincpa), and I extended upon it, resulting in the following file (schema_backup.ps1):

I have a .bat file that calls this, and is called from Task Scheduler. After the call to the Powershell file, I have:

for /f %f in ('dir /b d:\prod_schema_backup\stp\') do sqlcmd /S localhost /d dest_db /Q "DROP PROCEDURE %f"

That line will go thru the directory and drop the procedures it is going to recreate. If this wasn't a development environment, I would not like programmatically dropping procedures this way. I then rename all the stored procedure files to have .sql:

powershell Dir d:\prod_schema_backup\stp\ | Rename-Item -NewName { $_.name + ".sql" }

And then run:

for /f %f in ('dir /b d:\prod_schema_backup\stp\') do sqlcmd /S localhost /d dest_db /E /i "%f".sql

And that iterates through all the .sql files and recreates the stored procedures. I hope that any part of this will prove to be helpful to someone.

I know some things have changed in AC 2010. However, the old-fashioned ADODB is, as far as I know, the best way to go in VBA. An Example:

Dim cn As ADODB.Connection
Dim cmd As ADODB.Command
Dim prm As ADODB.Parameter
Dim rs As ADODB.Recordset
Dim colReturn As New Collection

Dim SQL As String
SQL = _
    "SELECT c.ClientID, c.LastName, c.FirstName, c.MI, c.DOB, c.SSN, " & _
    "c.RaceID, c.EthnicityID, c.GenderID, c.Deleted, c.RecordDate " & _
    "FROM tblClient AS c " & _
    "WHERE c.ClientID = @ClientID"

Set cn = New ADODB.Connection
Set cmd = New ADODB.Command

With cn
    .Provider = DataConnection.MyADOProvider
    .ConnectionString = DataConnection.MyADOConnectionString
    .Open
End With

With cmd
    .CommandText = SQL
    .ActiveConnection = cn
    Set prm = .CreateParameter("@ClientID", adInteger, adParamInput, , mlngClientID)
    .Parameters.Append prm
End With

Set rs = cmd.Execute

With rs
    If Not .EOF Then
        Do Until .EOF
            mstrLastName = Nz(!LastName, "")
            mstrFirstName = Nz(!FirstName, "")
            mstrMI = Nz(!MI, "")
            mdDOB = !DOB
            mstrSSN = Nz(!SSN, "")
            mlngRaceID = Nz(!RaceID, -1)
            mlngEthnicityID = Nz(!EthnicityID, -1)
            mlngGenderID = Nz(!GenderID, -1)
            mbooDeleted = Deleted
            mdRecordDate = Nz(!RecordDate, "")

            .MoveNext
        Loop
    End If
    .Close
End With

cn.Close

Set rs = Nothing
Set cn = Nothing

For the record, rjson and RJSONIO do change the file type, but they don't really parse per se. For instance, I receive ugly MongoDB data in JSON format, convert it with rjson or RJSONIO, then use unlist and tons of manual correction to actually parse it into a usable matrix.

div.style yields an object (CSSStyleDeclaration). Since it's an object, you can alternatively use the following:

div.style["top"] = "200px";
div.style["left"] = "200px";

This is useful, for example, if you need to access a "variable" property:

div.style[prop] = "200px";

You could theoretically do the entire thing as simply:

using System;
using System.Collections.Generic;
using System.Linq; 
using System.Text;

namespace consoleHelloWorld {
class Program {
    static void Main(string[] args) {
       Console.WriteLine(DateTime.Now.ToString("MM.dd.yyyy"));
    }
  }
}

I was stuck trying to implement this in typescript, all of the above would not work. I had to first cast the element in order for typescript to have access to the contentWindow.

let iframe = document.getElementById('frameId') as HTMLIFrameElement;
iframe.contentWindow.print();

I'm turning my comment to an answer, so it can be accepted and this question no longer remains unanswered.

The most likely cause of this is a malformed response, which includes characters before the initial <?xml …>. So please have a look at the document as transferred over HTTP, and fix this on the server side.

Adding to Rob?'s answer: in case you want to print rather large numbers, using thousand separators can be a great help (note the comma).

>>> f'{a*1000:,.2f}'
'10,123.40'

If your object contains a set of data you want to bind your object's iter to, you can cheat and do this:

>>> class foo:
    def __init__(self, *params):
           self.data = params
    def __iter__(self):
        if hasattr(self.data[0], "__iter__"):
            return self.data[0].__iter__()
        return self.data.__iter__()
>>> d=foo(6,7,3,8, "ads", 6)
>>> for i in d:
    print i
6
7
3
8
ads
6

C has 'for' and 'while' keywords. If a foreach statement in a language like C# looks like this ...

foreach (Element element in collection)
{
}

... then the equivalent of this foreach statement in C might be be like:

for (
    Element* element = GetFirstElement(&collection);
    element != 0;
    element = GetNextElement(&collection, element)
    )
{
    //TODO: do something with this element instance ...
}

Is Java smart enough to skip checking bool2 and bool2 if bool1 was evaluated to false?

Its not a matter of being smart, its a requirement specified in the language. Otherwise you couldn't write expressions like.

if(s != null && s.length() > 0)

or

if(s == null || s.length() == 0)

BTW if you use & and | it will always evaluate both sides of the expression.

With trackerless/DHT torrents, peer IP addresses are stored in the DHT using the BitTorrent infohash as the key. Since all a tracker does, basically, is respond to put/get requests, this functionality corresponds exactly to the interface that a DHT (distributed hash table) provides: it allows you to look up and store IP addresses in the DHT by infohash.

So a "get" request would look up a BT infohash and return a set of IP addresses. A "put" stores an IP address for a given infohash. This corresponds to the "announce" request you would otherwise make to the tracker to receive a dictionary of peer IP addresses.

In a DHT, peers are randomly assigned to store values belonging to a small fraction of the key space; the hashing ensures that keys are distributed randomly across participating peers. The DHT protocol (Kademlia for BitTorrent) ensures that put/get requests are routed efficiently to the peers responsible for maintaining a given key's IP address lists.

C doesn't support exceptions. You can try compiling your C code as C++ with Visual Studio or G++ and see if it'll compile as-is. Most C applications will compile as C++ without major changes, and you can then use the try... catch syntax.

Try either

• sudo apt-get install php-zip or
• sudo apt-get install php5.6-zip

Then, you might have to restart your web server.

• sudo service apache2 restart or
• sudo service nginx restart

If you are installing on centos or fedora OS then use yum in place of apt-get. example:-

sudo yum install php-zip or sudo yum install php5.6-zip and sudo service httpd restart

You should try detect the first line.

Then the:

if(n == 0){
  line = words[n]+"\n";
}

I'm not sure, but maybe it helps.

As mentioned by few users, below code can help find all the fields in a given class.

TestClass testObject= new TestClass().getClass();
Method[] methods = testObject.getMethods();
for (Method method:methods)
{
    String name=method.getName();
    if(name.startsWith("get"))
    {
        System.out.println(name.substring(3));
    }else if(name.startsWith("is"))
    {
        System.out.println(name.substring(2));
    }
}

However a more interesting approach is below:

With the help of Jackson library, I was able to find all class properties of type String/integer/double, and respective values in a Map class. (without using reflections api!)

TestClass testObject = new TestClass();
com.fasterxml.jackson.databind.ObjectMapper m = new com.fasterxml.jackson.databind.ObjectMapper();

Map<String,Object> props = m.convertValue(testObject, Map.class);

for(Map.Entry<String, Object> entry : props.entrySet()){
    if(entry.getValue() instanceof String || entry.getValue() instanceof Integer || entry.getValue() instanceof Double){
        System.out.println(entry.getKey() + "-->" + entry.getValue());
    }
}

It may not be appropriate... but it helped me.

<input placeholder="Date" class="textbox-n" type="text" onfocus="(this.type='date')" id="date">

The problem is that you aren't correctly escaping the input string, try:

echo "\"member\":\"time\"" | grep -e "member\""

Alternatively, you can use unescaped double quotes within single quotes:

echo '"member":"time"' | grep -e 'member"'

It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd').

Create a login for the user

Drop and re-create the user, WITH the login you created.

There are other topics discussing how to replicate the permissions of your user. I recommend that you take the opportunity to define those permissions in a Role and call sp_addrolemember to add the user to the Role.

C:\Users\\Anaconda3

I just added above path , to my path environment variables and it worked. Now, all we have to do is to move to the .py script location directory, open the cmd with that location and run to see the output.

You can use normal file operation to create an error log. Just refer this and input this link: PHP File Handling

I had a similar problem and solved it by focusing on the dialog after open:

var $dialog = $("#pnlFiltros")
    .dialog({
        autoOpen: false,
        hide: "puff",                   
        width: dWidth,
        height: 'auto',
        draggable: true,
        resizable: true,
        closeOnScape : true,
        position: [x,y]                    
    });
$dialog.dialog('open');
$("#pnlFiltros").focus(); //focus on the div being dialogued (is that a word?)

But in my case the first element is an anchor, so I don't know if in your case that will leave the datepicker opened.

EDIT: only works on IE

#include <stdio.h>

typedef struct { char* c; char b; } a;

int main()
{
    printf("sizeof(a) == %d", sizeof(a));
}

I get "sizeof(a) == 8", on a 32-bit machine. The total size of the structure will depend on the packing: In my case, the default packing is 4, so 'c' takes 4 bytes, 'b' takes one byte, leaving 3 padding bytes to bring it to the next multiple of 4: 8. If you want to alter this packing, most compilers have a way to alter it, for example, on MSVC:

#pragma pack(1)
typedef struct { char* c; char b; } a;

gives sizeof(a) == 5. If you do this, be careful to reset the packing before any library headers!

Below command works for me. Provided that all required jars including testng jar kept inside lib.

java -cp "lib/*" org.testng.TestNG testng.xml

Take a look at this forum http://htmlcoderhelper.com/why-is-using-a-wild-card-with-a-java-import-statement-bad/. Theres a discussion on how using wildcards can lead to conflicts if you add new classes to the packages and if there are two classes with the same name in different packages where only one of them will be imported.

Update

List<Integer> i = new ArrayList<Integer>(Arrays.asList(0,1,2,3,4,5,6,7,8,9,10));
List<Integer> j = new ArrayList<Integer>();

You need to specify the type for array list or the compiler will give that warning because it cannot identify that you are using the list in a type safe way.

PyXML works well.

You didn't say what platform you're using, however if you're on Ubuntu you can get it with sudo apt-get install python-xml. I'm sure other Linux distros have it as well.

If you're on a Mac, xpath is already installed but not immediately accessible. You can set PY_USE_XMLPLUS in your environment or do it the Python way before you import xml.xpath:

if sys.platform.startswith('darwin'):
    os.environ['PY_USE_XMLPLUS'] = '1'

In the worst case you may have to build it yourself. This package is no longer maintained but still builds fine and works with modern 2.x Pythons. Basic docs are here.

It is not entirely clear what you want, but I would use numpy.random.randint:

import numpy.random as nprnd
import timeit

t1 = timeit.Timer('[random.randint(0, 1000) for r in xrange(10000)]', 'import random') # v1

### Change v2 so that it picks numbers in (0, 10000) and thus runs...
t2 = timeit.Timer('random.sample(range(10000), 10000)', 'import random') # v2
t3 = timeit.Timer('nprnd.randint(1000, size=10000)', 'import numpy.random as nprnd') # v3

print t1.timeit(1000)/1000
print t2.timeit(1000)/1000
print t3.timeit(1000)/1000

which gives on my machine:

0.0233682730198
0.00781716918945
0.000147947072983

Note that randint is very different from random.sample (in order for it to work in your case I had to change the 1,000 to 10,000 as one of the commentators pointed out -- if you really want them from 0 to 1,000 you could divide by 10).

And if you really don't care what distribution you are getting then it is possible that you either don't understand your problem very well, or random numbers -- with apologies if that sounds rude...

Yes -- use math.nan.

>>> from math import nan
>>> print(nan)
nan
>>> print(nan + 2)
nan
>>> nan == nan
False
>>> import math
>>> math.isnan(nan)
True

Before Python 3.5, one could use float("nan") (case insensitive).

Note that checking to see if two things that are NaN are equal to one another will always return false. This is in part because two things that are "not a number" cannot (strictly speaking) be said to be equal to one another -- see What is the rationale for all comparisons returning false for IEEE754 NaN values? for more details and information.

Instead, use math.isnan(...) if you need to determine if a value is NaN or not.

Furthermore, the exact semantics of the == operation on NaN value may cause subtle issues when trying to store NaN inside container types such as list or dict (or when using custom container types). See Checking for NaN presence in a container for more details.

You can also construct NaN numbers using Python's decimal module:

>>> from decimal import Decimal
>>> b = Decimal('nan')
>>> print(b)
NaN
>>> print(repr(b))
Decimal('NaN')
>>>
>>> Decimal(float('nan'))
Decimal('NaN')
>>> 
>>> import math
>>> math.isnan(b)
True

math.isnan(...) will also work with Decimal objects.

However, you cannot construct NaN numbers in Python's fractions module:

>>> from fractions import Fraction
>>> Fraction('nan')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python35\lib\fractions.py", line 146, in __new__
    numerator)
ValueError: Invalid literal for Fraction: 'nan'
>>>
>>> Fraction(float('nan'))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python35\lib\fractions.py", line 130, in __new__
    value = Fraction.from_float(numerator)
  File "C:\Python35\lib\fractions.py", line 214, in from_float
    raise ValueError("Cannot convert %r to %s." % (f, cls.__name__))
ValueError: Cannot convert nan to Fraction.

Incidentally, you can also do float('Inf'), Decimal('Inf'), or math.inf (3.5+) to assign infinite numbers. (And also see math.isinf(...))

However doing Fraction('Inf') or Fraction(float('inf')) isn't permitted and will throw an exception, just like NaN.

If you want a quick and easy way to check if a number is neither NaN nor infinite, you can use math.isfinite(...) as of Python 3.2+.

If you want to do similar checks with complex numbers, the cmath module contains a similar set of functions and constants as the math module:

• cmath.isnan(...)
• cmath.isinf(...)
• cmath.isfinite(...) (Python 3.2+)
• cmath.nan (Python 3.6+; equivalent to complex(float('nan'), 0.0))
• cmath.nanj (Python 3.6+; equivalent to complex(0.0, float('nan')))
• cmath.inf (Python 3.6+; equivalent to complex(float('inf'), 0.0))
• cmath.infj (Python 3.6+; equivalent to complex(0.0, float('inf')))

I like this short video here mesos learning material

with bare metal clusters, you would need to spawn stacks like HDFS, SPARK, MR etc... so if you launch tasks related to these using only bare metal cluster management, there will be a lot cold starting time.

with mesos, you can install these services on top of the bare metals and you can avoid the bring up time of those base services. This is something mesos does well. and can be utilised by kubernetes building on top of it.

Assuming your page is available under "http://example.com"

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://example.com")

Select element by id:

inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')

Now you can simulate hitting ENTER:

inputElement.send_keys(Keys.ENTER)

or if it is a form you can submit:

inputElement.submit() 

Instead of typedef struct { ... } pos; you should be doing struct pos { ... };. The issue here is that you are using the pos type name before it is defined. By moving the name to the top of the struct definition, you are able to use that name within the struct definition itself.

Further, the typedef struct { ... } name; pattern is a C-ism, and doesn't have much place in C++.

To answer your question about inline, there is no difference in this case. When a method is defined within the struct/class definition, it is implicitly declared inline. When you explicitly specify inline, the compiler effectively ignores it because the method is already declared inline.

(inline methods will not trigger a linker error if the same method is defined in multiple object files; the linker will simply ignore all but one of them, assuming that they are all the same implementation. This is the only guaranteed change in behavior with inline methods. Nowadays, they do not affect the compiler's decision regarding whether or not to inline functions; they simply facilitate making the function implementation available in all translation units, which gives the compiler the option to inline the function, if it decides it would be beneficial to do so.)

This is what I am going to use based on marc_s answer:

SELECT 
SUBSTRING(DATA.value('(/PAGECONTENT/TEXT)[1]', 'VARCHAR(100)'),PATINDEX('%NORTH%',DATA.value('(/PAGECONTENT/TEXT)[1]', 'VARCHAR(100)')) - 20,999)

FROM WEBPAGECONTENT 
WHERE COALESCE(PATINDEX('%NORTH%',DATA.value('(/PAGECONTENT/TEXT)[1]', 'VARCHAR(100)')),0) > 0

Return a substring on the search where the search criteria exists

Two-liner:

var a = []; 
while(a.push([]) < 10);

It will generate an array a of the length 10, filled with arrays. (Push adds an element to an array and returns the new length)

Try putting the height into one of the cells, like this:

<table class="tableContainer" cellspacing="10px">
 <tr>
  <td style="height:15px;">NHS Number</td>
  <td>&#160;</td>

Note however, that you won't be able to make the cell smaller than the content requires it to be. In that case you would have to make the text smaller first.

If you need format 00:00:00 in string, you should use SimpleDateFormat as below. Using "H "instead "h".

Date today = new Date();
SimpleDateFormat ft = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss"); 
//not SimpleDateFormat("dd-MM-yyyy hh:mm:ss")
Calendar calendarDM = Calendar.getInstance();
calendarDM.setTime(today);
calendarDM.set(Calendar.HOUR, 0);
calendarDM.set(Calendar.MINUTE, 0);
calendarDM.set(Calendar.SECOND, 0);
System.out.println("Current Date: " + ft.format(calendarDM.getTime()));

//Result is: Current Date: 29-10-2018 00:00:00

I find this one-line code as most efficient and useful:

File file = new File(ClassLoader.getSystemResource("com/path/to/file.txt").getFile());

Works like a charm.

Depends how much you like the linq query syntax, you can use the extension methods directly like:

var item = Items.First(i => i.Id == 123);

And if you don't want to throw an error if the list is empty, use FirstOrDefault which returns the default value for the element type (null for reference types):

var item = Items.FirstOrDefault(i => i.Id == 123);

if (item != null)
{
    // found it
}

Single() and SingleOrDefault() can also be used, but if you are reading from a database or something that already guarantees uniqueness I wouldn't bother as it has to scan the list to see if there's any duplicates and throws. First() and FirstOrDefault() stop on the first match, so they are more efficient.

Of the First() and Single() family, here's where they throw:

• First() - throws if empty/not found, does not throw if duplicate
• FirstOrDefault() - returns default if empty/not found, does not throw if duplicate
• Single() - throws if empty/not found, throws if duplicate exists
• SingleOrDefault() - returns default if empty/not found, throws if duplicate exists

As far as I can tell, there are three main contenders: Table-Valued Parameters, delimited list string, and JSON string.

Since 2016, you can use the built-in STRING_SPLIT if you want the delimited route: https://docs.microsoft.com/en-us/sql/t-sql/functions/string-split-transact-sql

That would probably be the easiest/most straightforward/simple approach.

Also since 2016, JSON can be passed as a nvarchar and used with OPENJSON: https://docs.microsoft.com/en-us/sql/t-sql/functions/openjson-transact-sql

That's probably best if you have a more structured data set to pass that may be significantly variable in its schema.

TVPs, it seems, used to be the canonical way to pass more structured parameters, and they are still good if you need that structure, explicitness, and basic value/type checking. They can be a little more cumbersome on the consumer side, though. If you don't have 2016+, this is probably the default/best option.

I think it's a trade off between any of these concrete considerations as well as your preference for being explicit about the structure of your params, meaning even if you have 2016+, you may prefer to explicitly state the type/schema of the parameter rather than pass a string and parse it somehow.

Create table and have required columns that are used for creating table in csv file.

1. Open postgres and right click on target table which you want to load & select import and Update the following steps in file options section

2. Now browse your file in filename

3. Select csv in format

4. Encoding as ISO_8859_5

Now goto Misc. options and check header and click on import.

Download the tarball, transfer it to your FreeBSD machine and extract it, afterwards run python setup.py install and you're done!

EDIT: Just to add on that, you can also install the tarballs with pip now.

Use button.layer.cornerRadius, button.layer.borderColor and button.layer.borderWidth. Note that borderColor requires a CGColor, so you could say (Swift 3/4):

button.backgroundColor = .clear
button.layer.cornerRadius = 5
button.layer.borderWidth = 1
button.layer.borderColor = UIColor.black.cgColor

This can also be set in the configuration file matplotlibrc (as explained in the error message), for instance:

# The default backend; one of GTK GTKAgg GTKCairo GTK3Agg GTK3Cairo
# CocoaAgg MacOSX Qt4Agg Qt5Agg TkAgg WX WXAgg Agg Cairo GDK PS PDF SVG
backend : Agg

That way, the backend does not need to be hardcoded if the code is shared with other people. For more information, check the documentation.

to set the height of table, you need to first set css property "display: block" then you can add "width/height" properties. I find this Mozilla Article a very good resource to learn how to style tables : Link

For PHP >= 5.4 use

$var = []; 

Not sure if it's faster than

$var = array();

but at least looks cleaner.

You can define a boolean and change it to false when you want to stop handler. Like this..

boolean stop = false;

handler.postDelayed(new Runnable() {
    @Override
    public void run() {

        //do your work here..

        if (!stop) {
            handler.postDelayed(this, delay);
        }
    }
}, delay);

Use Method to Serialize and Deserialize Collection object from memory. This works on Collection Data Types. This Method will Serialize collection of any type to a byte stream. Create a Seperate Class SerilizeDeserialize and add following two methods:

public class SerilizeDeserialize
{

    // Serialize collection of any type to a byte stream

    public static byte[] Serialize<T>(T obj)
    {
        using (MemoryStream memStream = new MemoryStream())
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            binSerializer.Serialize(memStream, obj);
            return memStream.ToArray();
        }
    }

    // DSerialize collection of any type to a byte stream

    public static T Deserialize<T>(byte[] serializedObj)
    {
        T obj = default(T);
        using (MemoryStream memStream = new MemoryStream(serializedObj))
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            obj = (T)binSerializer.Deserialize(memStream);
        }
        return obj;
    }

}

How To use these method in your Class:

ArrayList arrayListMem = new ArrayList() { "One", "Two", "Three", "Four", "Five", "Six", "Seven" };
Console.WriteLine("Serializing to Memory : arrayListMem");
byte[] stream = SerilizeDeserialize.Serialize(arrayListMem);

ArrayList arrayListMemDes = new ArrayList();

arrayListMemDes = SerilizeDeserialize.Deserialize<ArrayList>(stream);

Console.WriteLine("DSerializing From Memory : arrayListMemDes");
foreach (var item in arrayListMemDes)
{
    Console.WriteLine(item);
}

On client:

  axios.get('/api', {
      params: {
        foo: 'bar'
      }
    });

On server:

function get(req, res, next) {

  let param = req.query.foo
   .....
}

I tried all the solutions but it still wasn't sufficient. After some more digging I eventually found I had also to set the 'file_priv' flag, and restart mysql.

To resume :

Grant the privileges :

> GRANT ALL PRIVILEGES
  ON my_database.* 
  to 'my_user'@'localhost';

> GRANT FILE ON *.* TO my_user;

> FLUSH PRIVILEGES; 

Set the flag :

> UPDATE mysql.user SET File_priv = 'Y' WHERE user='my_user' AND host='localhost';

Finally restart the mysql server:

$ sudo service mysql restart

After that, I could write into the secure_file_priv directory. For me it was /var/lib/mysql-files/, but you can check it with the following command :

> SHOW VARIABLES LIKE "secure_file_priv";

Iterable is a generic interface. A problem you might be having (you haven't actually said what problem you're having, if any) is that if you use a generic interface/class without specifying the type argument(s) you can erase the types of unrelated generic types within the class. An example of this is in Non-generic reference to generic class results in non-generic return types.

So I would at least change it to:

public class ProfileCollection implements Iterable<Profile> { 
    private ArrayList<Profile> m_Profiles;

    public Iterator<Profile> iterator() {        
        Iterator<Profile> iprof = m_Profiles.iterator();
        return iprof; 
    }

    ...

    public Profile GetActiveProfile() {
        return (Profile)m_Profiles.get(m_ActiveProfile);
    }
}

and this should work:

for (Profile profile : m_PC) {
    // do stuff
}

Without the type argument on Iterable, the iterator may be reduced to being type Object so only this will work:

for (Object profile : m_PC) {
    // do stuff
}

This is a pretty obscure corner case of Java generics.

If not, please provide some more info about what's going on.

For people trying to grab the component instance inside a *ngIf or *ngSwitchCase, you can follow this trick.

Create an init directive.

import {
    Directive,
    EventEmitter,
    Output,
    OnInit,
    ElementRef
} from '@angular/core';

@Directive({
    selector: '[init]'
})
export class InitDirective implements OnInit {
    constructor(private ref: ElementRef) {}

    @Output() init: EventEmitter<ElementRef> = new EventEmitter<ElementRef>();

    ngOnInit() {
        this.init.emit(this.ref);
    }
}

Export your component with a name such as myComponent

@Component({
    selector: 'wm-my-component',
    templateUrl: 'my-component.component.html',
    styleUrls: ['my-component.component.css'],
    exportAs: 'myComponent'
})
export class MyComponent { ... }

Use this template to get the ElementRef AND MyComponent instance

<div [ngSwitch]="type">
    <wm-my-component
           #myComponent="myComponent"
           *ngSwitchCase="Type.MyType"
           (init)="init($event, myComponent)">
    </wm-my-component>
</div>

Use this code in TypeScript

init(myComponentRef: ElementRef, myComponent: MyComponent) {
}

>>> int("0xff", 16)
255

or

>>> int("FFFF", 16)
65535

Read the docs.

$("#searchPkgKeyWord").autocomplete("searchURL",
        {
            width: 298,
            max: 1000,
            selectFirst: false
        }).result(function (event, row, formatted) {
            callback(row[1]);
        }).focus(function(){
            $(this).click(); //once the input focus, all the research will show
        });

Kotlin's way -

fun Context.bitMapFromImgUrl(imageUrl: String, callBack: (bitMap: Bitmap) -> Unit) {
    GlideApp.with(this)
        .asBitmap()
        .load(imageUrl)
        .into(object : CustomTarget<Bitmap>() {
            override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
                callBack(resource)
            }

            override fun onLoadCleared(placeholder: Drawable?) {
                // this is called when imageView is cleared on lifecycle call or for
                // some other reason.
                // if you are referencing the bitmap somewhere else too other than this imageView
                // clear it here as you can no longer have the bitmap
            }
        })
}

something like this?

#sticky-sidebar {_x000D_

I didn't find this solution here. It removes all of it using the cowplot package:

library(cowplot)

p + theme_nothing() +
theme(legend.position="none") +
scale_x_continuous(expand=c(0,0)) +
scale_y_continuous(expand=c(0,0)) +
labs(x = NULL, y = NULL)

Just noticed that the same thing can be accomplished using theme.void() like this:

p + theme_void() +
theme(legend.position="none") +
scale_x_continuous(expand=c(0,0)) +
scale_y_continuous(expand=c(0,0)) +
labs(x = NULL, y = NULL)

It seems that the idiomatic way to do this is to provide a close() method (or similar), and call it explicitely.

For those who are using MyScript the Web App and are struggling with the body scrolling/dragging (on iPad and Tablets) instead of actually writing:

<body touch-action="none" unresolved>

That fixed it for me.

in my case , this solve my issue

rv.setAdapter(null);
rv.setItemAnimator(null);

PS: my problem ocur when i do seache filter in my recyclerview adapter

It is simpler just to run an exact copy like below to put the copy in as the last sheet

Sub Test()
Dim ws1 As Worksheet
Set ws1 = ThisWorkbook.Worksheets("Master")
ws1.Copy ThisWorkbook.Sheets(Sheets.Count)
End Sub

just make a new page and add this code

 <?php
 if(!function_exists('apache_get_modules') ){ phpinfo(); exit; }
 $res = 'Module Unavailable';
 if(in_array('mod_rewrite',apache_get_modules())) 
 $res = 'Module Available';
?>
<html>
<head>
<title>A mod_rewrite availability check !</title></head>
<body>
<p><?php echo apache_get_version(),"</p><p>mod_rewrite $res"; ?></p>
</body>
</html>

and run this page then find will able to know module is Available or not if not then you can ask to your hosting or if you want to enable it in local machine then check this youtube step by step tutorial related to enable rewrite module in wamp apache https://youtu.be/xIspOX9FuVU?t=1m43s Wamp server icon -> Apache -> Apache Modules and check the rewrite module option

One can also use this kind of condition:

<div [ngStyle]="myBooleanVar && {'color': 'red'}"></div>

It requires a bit less string concatenation...

If you use a website and you fill out a form to submit information (your social security number for example) you want to be sure that the information is being sent to the site you think it's being sent to. So browsers were built to say, by default, 'Do not send information to a domain other than the domain being visited).

Eventually that became too limiting but the default idea still remains in browsers. Don't let the web page send information to a different domain. But this is all browser checking. Chrome and firefox, etc have built in code that says 'before send this request, we're going to check that the destination matches the page being visited'.

Postman (or CURL on the cmd line) doesn't have those built in checks. You're manually interacting with a site so you have full control over what you're sending.

A more general answer would be to import java.util.Date, then when you need to set a timestamp equal to the current date, simply set it equal to new Date().

For me a simple

exit

works. This is from within the screen session.

<html>
    <body>
        <a href="#" onclick="DoEdit('Preliminary Assessment &quot;Mini&quot;'); return false;">edit</a>
    </body>
</html>

Should do the trick.

This bit gives you ability to paginate using SQL Server, and newer versions of MySQL and carries the total number of rows in every row. Uses your pimary key to count number of unique rows.

WITH T AS
(  
  SELECT TABLE_ID, ROW_NUMBER() OVER (ORDER BY TABLE_ID) AS RN
  , (SELECT COUNT(TABLE_ID) FROM TABLE) AS TOTAL 
  FROM TABLE (NOLOCK)
)

SELECT T2.FIELD1, T2.FIELD2, T2.FIELD3, T.TOTAL 
FROM TABLE T2 (NOLOCK)
INNER JOIN T ON T2.TABLE_ID=T.TABLE_ID
WHERE T.RN >= 100
AND T.RN < 200

Web API works very nicely if you accept the fact that you are using HTTP. It's when you start trying to pretend that you are sending objects over the wire that it starts to get messy.

 public class TextController : ApiController
    {
        public HttpResponseMessage Post(HttpRequestMessage request) {

            var someText = request.Content.ReadAsStringAsync().Result;
            return new HttpResponseMessage() {Content = new StringContent(someText)};

        }

    }

This controller will handle a HTTP request, read a string out of the payload and return that string back.

You can use HttpClient to call it by passing an instance of StringContent. StringContent will be default use text/plain as the media type. Which is exactly what you are trying to pass.

    [Fact]
    public void PostAString()
    {

        var client = new HttpClient();

        var content = new StringContent("Some text");
        var response = client.PostAsync("http://oak:9999/api/text", content).Result;

        Assert.Equal("Some text",response.Content.ReadAsStringAsync().Result);

    }

This is a program to show how to give input from system and also calculate sum at each level and average.

package NumericTest;

import java.util.Scanner;

public class SumAvg {


 public static void main(String[] args) {

 int i,n;
 System.out.println("Enter the number of inputs");
 Scanner sc = new Scanner(System.in);
 n=sc.nextInt();
 int a[] = new int [n];

    System.out.println("Enter the inputs");
   for(i=0;i<n;i++){
   a[i] = sc.nextInt();
  System.out.println("Inputs are " +a[i]);
 }

  int sum = 0;
  for(i=0;i<n;i++){
 sum = sum +a[i];
  System.out.println("Sums : " +sum);
 }
  int avg ;
  avg = sum/n;
  System.out.println("avg : " +avg);
  }
 }

treeset is an ordered set, but you can't access via an items index, just iterate through or go to beginning/end.

Try this:

net use * /delete /y

By default, Apache prohibits using an .htaccess file to apply rewrite rules, so

Step 1 — Enabling mod_rewrite (if not Enabled) First, we need to activate mod_rewrite. It's available but not enabled with a clean Apache 2 installation.

$ sudo a2enmod rewrite

This will activate the module or alert you that the module is already enabled. To put these changes into effect, restart Apache.

$ sudo systemctl restart apache2

mod_rewrite is now fully enabled. In the next step we will set up an .htaccess file that we'll use to define rewrite rules for redirects.

Step 2 — Setting Up .htaccess Open the default Apache configuration file using nano or your favorite text editor.

$ sudo nano /etc/apache2/sites-available/000-default.conf

Inside that file, you will find a block starting on the first line. Inside of that block, add the following new block so your configuration file looks like the following. Make sure that all blocks are properly indented.

/etc/apache2/sites-available/000-default.conf

<VirtualHost *:80>
    <Directory /var/www/html>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
    </Directory>

    . . . 
</VirtualHost>

Save and close the file. To put these changes into effect, restart Apache.

$ sudo systemctl restart apache2

Done. Your .htacess should work. This link may actually help somebody https://www.digitalocean.com/community/tutorials/how-to-rewrite-urls-with-mod_rewrite-for-apache-on-ubuntu-16-04

You question could be reformulated as "replace in the string the first space and everything following by nothing" . So this can be achieved with a simple regular expression:

$firstWord = preg_replace("/\s.*/", '', ltrim($myvalue));

I have added an optional call to ltrim() to be safe: this function remove spaces at the begin of string.

Function FileExists(fullFileName As String) As Boolean
    FileExists = VBA.Len(VBA.Dir(fullFileName)) > 0
End Function

My search led me here so might as well add my two cents worth of idea. If you are using Monkey friendly Twitter Bootstrap modal then you can do something like this:

    var dialog = new BootstrapDialog({
        id: 'myDialog',
        title: 'Title',
        closable: false,
        // whatever you like configuration here...
    });

    dialog.realize();
    if (isContentAYoutubeVideo()) {
        dialog.getModalDialog().css('width', '80%'); // set the width to whatever you like
    }
    dialog.open();

Hope this helps.

unfortunately, with "mvim -v", ALT plus arrow windows still does not work. I have not found any way to enable it :-(

I've found that using either of the following options works:

SET DEF OFF

or

SET SCAN OFF

I don't know enough about databases to know if one is better or "more right" than the other. Also, if there's something better than either of these, please let me know.

ini_set('memory_limit', '128M'); 

or

php.ini  =>  memory_limit = 128M

or

php_value memory_limit 128M

If you want the sum of all bars to be equal unity, weight each bin by the total number of values:

weights = np.ones_like(myarray) / len(myarray)
plt.hist(myarray, weights=weights)

Hope that helps, although the thread is quite old...

Note for Python 2.x: add casting to float() for one of the operators of the division as otherwise you would end up with zeros due to integer division

Based on twitter scroll trouble (http://ejohn.org/blog/learning-from-twitter/).

Here is my solution, throttling the js scroll event (usefull for mobile devices)

JS:

$(function() {
    var $document, didScroll, offset;
    offset = $('.menu').position().top;
    $document = $(document);
    didScroll = false;
    $(window).on('scroll touchmove', function() {
      return didScroll = true;
    });
    return setInterval(function() {
      if (didScroll) {
        $('.menu').toggleClass('fixed', $document.scrollTop() > offset);
        return didScroll = false;
      }
    }, 250);
  });

CSS:

.menu {
  background: pink;
  top: 5px;
}

.fixed {
  width: 100%;
  position: fixed;
  top: 0;
}

HTML:

<div class="menu">MENU FIXED ON TOP</div>

http://codepen.io/anon/pen/BgqHw

A rather roundabout way, just for completeness:

 for /f "delims=" %i in ('type CON') do set inp=%i

Of course that requires ^Z as a terminator, and so the Johannes answer is better in all practical ways.

I've all done, setting JAVA_HOME, JAVA8_HOME, ... and i had always the error. For me the solution was to set the version 2.1.0 of gradle to work with Jdk 1.8.0_92 and android studio 2.11

dependencies {
    classpath 'com.android.tools.build:gradle:2.1.0'
    //classpath 'com.android.tools.build:gradle:2.+'
}

If you only want to test for true against null/false, One I've just used and reads quite well is

bool? someCondition = null
if (someCondition.Equals(true))
...

Here is the best solution for searching inside HTML table while covering all of the table, (all td, tr in the table), pure javascript and as short as possible:

<input id='myInput' onkeyup='searchTable()' type='text'>

<table id='myTable'>
   <tr>
      <td>Apple</td>
      <td>Green</td>
   </tr>
   <tr>
      <td>Grapes</td>
      <td>Green</td>
   </tr>
   <tr>
      <td>Orange</td>
      <td>Orange</td>
   </tr>
</table>

<script>
function searchTable() {
    var input, filter, found, table, tr, td, i, j;
    input = document.getElementById("myInput");
    filter = input.value.toUpperCase();
    table = document.getElementById("myTable");
    tr = table.getElementsByTagName("tr");
    for (i = 0; i < tr.length; i++) {
        td = tr[i].getElementsByTagName("td");
        for (j = 0; j < td.length; j++) {
            if (td[j].innerHTML.toUpperCase().indexOf(filter) > -1) {
                found = true;
            }
        }
        if (found) {
            tr[i].style.display = "";
            found = false;
        } else {
            tr[i].style.display = "none";
        }
    }
}
</script>

You can either put the classes on the "row" or the "column"? Won't be visible on the cards (border) if you use it on the row. https://v4-alpha.getbootstrap.com/utilities/flexbox/#align-items

Some of the other answers here seem 'wacky'. Why would use a min-height or even worse a fixed height?

I thought this issue (equal heights) was part of the reason for progression away from floating block divs?

In my case, @ caused some sort of encoding problem, I still prefer my old way:

    sdf.setTimeZone(TimeZone.getTimeZone("-5GMT"));
    fecha = sdf.format(f);
    System.out.println(fecha);
}

I've just found this solution:

if(@getimagesize($remoteImageURL)){
    //image exists!
}else{
    //image does not exist.
}
