I fixed this using below method-

1. Copy url which is having connecting issue
2. Go to Android Studio->Settings->Http settings
3. In 'Test Connection', paste that url and press ok
4. On Ok click, Android Studio will ask to import certificate of that url, import it
5. That's it. Nothing else to be done and my issue was gone. No need to restart studio as well.

$newstr = substr_replace($oldstr, $str_to_insert, $pos, 0);

The most simple what I've found to get the XPath for a particular Element is to install FireBug extension for Firefox go to the site/webpage press F12 to bring up firebug; right select and right click the element on the page that you want to query and select "Inspect Element" Firebug will select the element in its IDE then right click the Element in Firebug and choose "Copy XPath" this function will give you the exact XPath Query you need to get the element you want using HTML Agility Library.

Using bcrypt you can solve this issue. Extending the @Reem answer for someone who is trying to automate the process using bash and python.

#!/bin/bash

pip install bcrypt
yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum -y install xmlstarlet

cat > /tmp/jenkinsHash.py <<EOF
import bcrypt
import sys

if not sys.argv[1]:
  sys.exit(10)

plaintext_pwd=sys.argv[1]
encrypted_pwd=bcrypt.hashpw(sys.argv[1], bcrypt.gensalt(rounds=10, prefix=b"2a"))
isCorrect=bcrypt.checkpw(plaintext_pwd, encrypted_pwd)

if not isCorrect:
   sys.exit(20);

print "{}".format(encrypted_pwd)
EOF

chmod +x /tmp/jenkinsHash.py
cd /var/lib/jenkins/users/admin*
pwd
while (( 1 )); do
    echo "Waiting for Jenkins to generate admin user's config file ..."

    if [[ -f "./config.xml" ]]; then
        break
    fi

    sleep 10
done

echo "Admin config file created"

admin_password=$(python /tmp/jenkinsHash.py password 2>&1)

# Repalcing the new passowrd
xmlstarlet -q ed --inplace -u "/user/properties/hudson.security.HudsonPrivateSecurityRealm_-Details/passwordHash" -v '#jbcrypt:'"$admin_password" config.xml

# Restart
systemctl restart jenkins
sleep 10

I have kept password hardcoded here but it can be a user input depending upon the requirement. Also make sure to add that sleep otherwise any other command revolving around Jenkins will fail.

Static members are universal members. They can be accessed from anywhere.

from selenium import webdriver

PROXY = "23.23.23.23:3128" # IP:PORT or HOST:PORT

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=%s' % PROXY)

chrome = webdriver.Chrome(options=chrome_options)
chrome.get("http://whatismyipaddress.com")

<?php
if(!@mysql_connect('127.0.0.1', 'root', '*your default password*'))
{
    echo "mysql not connected ".mysql_error();
    exit;

}
echo 'great work';
?>

if no error then you will get greatwork as output.

Try it saved my life XD XD

The interrupt process is hardware and OS dependent. So you will have very different behavior depending on where you run your python script. For example, on Windows machines we have Ctrl+C (SIGINT) and Ctrl+Break (SIGBREAK).

So while SIGINT is present on all systems and can be handled and caught, the SIGBREAK signal is Windows specific (and can be disabled in CONFIG.SYS) and is really handled by the BIOS as an interrupt vector INT 1Bh, which is why this key is much more powerful than any other. So if you're using some *nix flavored OS, you will get different results depending on the implementation, since that signal is not present there, but others are. In Linux you can check what signals are available to you by:

$ kill -l
 1) SIGHUP       2) SIGINT       3) SIGQUIT      4) SIGILL       5) SIGTRAP
 6) SIGABRT      7) SIGEMT       8) SIGFPE       9) SIGKILL     10) SIGBUS
11) SIGSEGV     12) SIGSYS      13) SIGPIPE     14) SIGALRM     15) SIGTERM
16) SIGURG      17) SIGSTOP     18) SIGTSTP     19) SIGCONT     20) SIGCHLD
21) SIGTTIN     22) SIGTTOU     23) SIGIO       24) SIGXCPU     25) SIGXFSZ
26) SIGVTALRM   27) SIGPROF     28) SIGWINCH    29) SIGPWR      30) SIGUSR1
31) SIGUSR2     32) SIGRTMAX

So if you want to catch the CTRL+BREAK signal on a linux system you'll have to check to what POSIX signal they have mapped that key. Popular mappings are:

CTRL+\     = SIGQUIT 
CTRL+D     = SIGQUIT
CTRL+C     = SIGINT
CTRL+Z     = SIGTSTOP 
CTRL+BREAK = SIGKILL or SIGTERM or SIGSTOP

In fact, many more functions are available under Linux, where the SysRq (System Request) key can take on a life of its own...

Immutable objects are simply objects whose state (the object's data) cannot change after construction. Examples of immutable objects from the JDK include String and Integer.

For example:(Point is mutable and string immutable)

     Point myPoint = new Point( 0, 0 );
    System.out.println( myPoint );
    myPoint.setLocation( 1.0, 0.0 );
    System.out.println( myPoint );

    String myString = new String( "old String" );
    System.out.println( myString );
    myString.replaceAll( "old", "new" );
    System.out.println( myString );

The output is:

java.awt.Point[0.0, 0.0]
java.awt.Point[1.0, 0.0]
old String
old String

Since Java 7 you can use java.util.Objects.equals(Object a, Object b):

These utilities include null-safe or null-tolerant methods

Long id1 = null;
Long id2 = 0l;
Objects.equals(id1, id2));

To delete a job which has not yet run, you need the atrm command. You can use atq command to get its number in the at list.

To kill a job which has already started to run, you'll need to grep for it using:

ps -eaf | grep <command name>

and then use kill to stop it.

A quicker way to do this on most systems is:

pkill <command name>

The same problem arrised for me when I installed Kaliko CMS Nuget Package. When I removed it, it started working fine again. So, your problem could be because of a recently installed Nuget Package. Uninstall it and your solution will work just fine.

You simply can't use View as a Header of ListView.

Because the view which is being passed in has to be inflated.

Look at my answer at Android ListView addHeaderView() nullPointerException for predefined Views for more info.

EDIT:

Look at this tutorial Android ListView and ListActivity - Tutorial .

EDIT 2: This link is broken Android ListActivity with a header or footer

JUST THIS WORKS!!

take care about your file name uppercase in tag and put PNG file inroot, and link to the filename without any path:

I switch between zsh and bash somewhat frequently. For a while, I used to have to source my bash_profile every switch. Then I found out you can (typically) do

exec bash --login

or just

exec bash -l

// in foo.h
class Foo {
    static const unsigned char* Msg;
};

// in foo.cpp
static const unsigned char Foo_Msg_data[] = {0x00,0x01};
const unsigned char* Foo::Msg = Foo_Msg_data;

Visual Studio (full version) is a "full-featured" and "convenient" development environment.

Visual Studio (free "Express" versions - only until 2017) are feature-centered and simplified versions of the full version. Feature-centered meaning that there are different versions (Visual Studio Web Developer, Visual Studio C#, etc.) depending on your goal.

Visual Studio (free Community edition - since 2015) is a simplified version of the full version and replaces the separated express editions used before 2015.

Visual Studio Code (VSCode) is a cross-platform (Linux, Mac OS, Windows) editor that can be extended with plugins to your needs.

For example, if you want to create an ASP.NET application using Visual Studio Code you need to perform several steps on your own to setup the project. There is a separate tutorial for each OS.

The Console.CancelKeyPress event is used for this. This is how it's used:

public static void Main(string[] args)
{
    Console.CancelKeyPress += delegate {
        // call methods to clean up
    };

    while (true) {}
}

When the user presses Ctrl + C the code in the delegate is run and the program exits. This allows you to perform cleanup by calling necessairy methods. Note that no code after the delegate is executed.

There are other situations where this won't cut it. For example, if the program is currently performing important calculations that can't be immediately stopped. In that case, the correct strategy might be to tell the program to exit after the calculation is complete. The following code gives an example of how this can be implemented:

class MainClass
{
    private static bool keepRunning = true;

    public static void Main(string[] args)
    {
        Console.CancelKeyPress += delegate(object sender, ConsoleCancelEventArgs e) {
            e.Cancel = true;
            MainClass.keepRunning = false;
        };

        while (MainClass.keepRunning) {
            // Do your work in here, in small chunks.
            // If you literally just want to wait until ctrl-c,
            // not doing anything, see the answer using set-reset events.
        }
        Console.WriteLine("exited gracefully");
    }
}

The difference between this code and the first example is that e.Cancel is set to true, which means the execution continues after the delegate. If run, the program waits for the user to press Ctrl + C. When that happens the keepRunning variable changes value which causes the while loop to exit. This is a way to make the program exit gracefully.

if you are using cp doesn't save existing files when copying folders of the same name. Lets say you have this folders:

/myFolder
  someTextFile.txt

/someOtherFolder
  /myFolder
    wellHelloThere.txt

Then you copy one over the other:

cp /someOtherFolder/myFolder /myFolder

result:

/myFolder
  wellHelloThere.txt

This is at least what happens on macOS and I wanted to preserve the diff files so I used rsync.

You can use the droidQuery library to handle flings, clicks, long clicks, and custom events. The implementation is built on my previous answer below, but droidQuery provides a slick, simple syntax:

//global variables    private boolean isSwiping = false;
private SwipeDetector.Direction swipeDirection = null;
private View v;//must be instantiated before next call.

//swipe-handling code
$.with(v).swipe(new Function() {
    @Override
    public void invoke($ droidQuery, Object... params) {
        if (params[0] == SwipeDetector.Direction.START)
            isSwiping = true;
        else if (params[0] == SwipeDetector.Direction.STOP) {
            if (isSwiping) {                    isSwiping = false;
                if (swipeDirection != null) {
                    switch(swipeDirection) {
                        case DOWN :                                //TODO: Down swipe complete, so do something
                            break;
                        case UP :
                            //TODO: Up swipe complete, so do something
                            break;
                        case LEFT :
                            //TODO: Left swipe complete, so do something
                            break;
                        case RIGHT :
                            //TODO: Right swipe complete, so do something
                            break;
                        default :                                break;
                    }
                }                }
        }
        else {
            swipeDirection = (SwipeDetector.Direction) params[0];
        }
    }
});

Original Answer

This answer uses a combination of components from the other answers here. It consists of the SwipeDetector class, which has an inner interface for listening for events. I also provide a RelativeLayout to show how to override a View's onTouch method to allow both swipe events and other detected events (such as clicks or long clicks).

Reader's Digest: (Spark 2.x)

For Example, if you have 3 directories holding csv files:

dir1, dir2, dir3

You then define paths as a string of comma delimited list of paths as follows:

paths = "dir1/,dir2/,dir3/*"

Then use the following function and pass it this paths variable

def get_df_from_csv_paths(paths):

        df = spark.read.format("csv").option("header", "false").\
            schema(custom_schema).\
            option('delimiter', '\t').\
            option('mode', 'DROPMALFORMED').\
            load(paths.split(','))
        return df

By then running:

df = get_df_from_csv_paths(paths)

You will obtain in df a single spark dataframe containing the data from all the csvs found in these 3 directories.

===========================================================================

Full Version:

In case you want to ingest multiple CSVs from multiple directories you simply need to pass a list and use wildcards.

For Example:

if your data_path looks like this:

's3://bucket_name/subbucket_name/2016-09-*/184/*,
s3://bucket_name/subbucket_name/2016-10-*/184/*,
s3://bucket_name/subbucket_name/2016-11-*/184/*,
s3://bucket_name/subbucket_name/2016-12-*/184/*, ... '

you can use the above function to ingest all the csvs in all these directories and subdirectories at once:

This would ingest all directories in s3 bucket_name/subbucket_name/ according to the wildcard patterns specified. e.g. the first pattern would look in

bucket_name/subbucket_name/

for all directories with names starting with

2016-09-

and for each of those take only the directory named

184

and within that subdirectory look for all csv files.

And this would be executed for each of the patterns in the comma delimited list.

This works way better than union..

Without changing the position to absolute, see below. This supports all recent browsers as well.

.vranger {_x000D_
  margin-top: 50px;_x000D_
   transform: rotate(270deg);_x000D_
  -moz-transform: rotate(270deg); /*do same for other browsers if required*/_x000D_
}

<input type="range" class="vranger"/>

for very old browsers, you can use -sand-transform: rotate(10deg); from CSS sandpaper

or use

prefix selector such as -ms-transform: rotate(270deg); for IE9

with r55 you have to change
rotationMatrix.multiplySelf( object.matrix );
to
rotationMatrix.multiply( object.matrix );

You can use TEXT type, which is not limited to 64KB.

using from ListSelectionModel:

ListSelectionModel cellSelectionModel = table.getSelectionModel();
cellSelectionModel.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

cellSelectionModel.addListSelectionListener(new ListSelectionListener() {
  public void valueChanged(ListSelectionEvent e) {
    String selectedData = null;

    int[] selectedRow = table.getSelectedRows();
    int[] selectedColumns = table.getSelectedColumns();

    for (int i = 0; i < selectedRow.length; i++) {
      for (int j = 0; j < selectedColumns.length; j++) {
        selectedData = (String) table.getValueAt(selectedRow[i], selectedColumns[j]);
      }
    }
    System.out.println("Selected: " + selectedData);
  }

});

see here.

Of course you can.

Your HTML there is just fine. To style the elements with css you can use the following approaches:

#y {
    ...
}

.x {
    ...
}

#y.x {
    ...
}

Also you can add as many classes as you wish to your element

<div id="id" class="classA classB classC ...">
</div>

And you can style that element using a selector with any combination of the classes and id. For example:

#id.classA.classB.classC {
     ...
}

#id.classC {
}

For those like me who struggled to get @Sunny Shah accepted answer to work on iPads. You need to set the "Requires full screen" checkbox on in the project settings. Note that this will prevent your app from working on multitasking mode which may or not be acceptable.

Maybe this

$products = $art->products->take($limit)->skip($offset)->get();

You need to declare a table type which contains the same number of columns your store procedure is returning. Data types of the columns in the table type and the columns returned by the procedures should be same

declare @MyTableType as table
(
FIRSTCOLUMN int
,.....
)  

Then you need to insert the result of your stored procedure in your table type you just defined

Insert into @MyTableType 
EXEC [dbo].[MyStoredProcedure]

In the end just select from your table type

Select * from @MyTableType

I'd mount and then run the image with a daemon, just any as given here;

docker run -d -v /blah1/blah2:/mnt --name mntcontainer ubuntu /bin/sh -c "while true; do echo hello world; sleep 1; done"

then

docker exec -it mntcontainer bash

Jut use

ArrayAdapter<String> adaptername = new ArrayAdapter<String>(this,
            android.R.layout.simple_dropdown_item_1line, your array list);

list all your docker images:

list all existed docker containers:

docker ps -a

delete all the targeted containers, which is using the image that you want to delete:

docker rm <container-id>

delete the targeted image:

docker rmi <image-name:image-tag or image-id>

Even though your JDK in eclipse is 1.7, you need to make sure eclipse compilance level also set to 1.7. You can check compilance level--> Window-->Preferences--> Java--Compiler--compilance level.

Unsupported major minor error happens in cases where compilance level doesn't match with runtime.

You have two ways of ignoring files:

• .gitignore in any folder will ignore the files as specified in the file for that folder. Using wildcards is possible.
• .git/info/exclude holds the global ignore pattern, similar to the global-ignores in subversions configuration file.

The jQueryUI provides a extension to animate function that allows you to animate css class.

edit: Example here

There are also methods to add/remove/toggle class which you might also be interested in.

you have to create an entry inside res/menu,override onCreateOptionsMenu and inflate it

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.yourentry, menu);
    return true;
}

an entry for the menu could be:

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:id="@+id/action_cart"
        android:icon="@drawable/cart"
        android:orderInCategory="100"
        android:showAsAction="always"/> 
</menu>

select name, games, goals
from tblMadrid where name = 'ronaldo'
union
select name, games, goals
from tblBarcelona where name = 'messi'
ORDER  BY goals 

The RFC 7807: Problem Details for HTTP APIs is at the moment the closest thing we have to an official standard.

I have expanded on the previous suggestions. This works for me, with multiple radios coupled by the same name.

$("input[type='radio']").click(function()
{
  var previousValue = $(this).attr('previousValue');
  var name = $(this).attr('name');

  if (previousValue == 'checked')
  {
    $(this).removeAttr('checked');
    $(this).attr('previousValue', false);
  }
  else
  {
    $("input[name="+name+"]:radio").attr('previousValue', false);
    $(this).attr('previousValue', 'checked');
  }
});

The types in an Object[] will never really be primitive - because you've got references! Here the type of i is int whereas the type of the object referenced by o is Integer (due to auto-boxing).

It sounds like you need to find out whether the type is a "wrapper for primitive". I don't think there's anything built into the standard libraries for this, but it's easy to code up:

import java.util.*;

public class Test
{
    public static void main(String[] args)        
    {
        System.out.println(isWrapperType(String.class));
        System.out.println(isWrapperType(Integer.class));
    }

    private static final Set<Class<?>> WRAPPER_TYPES = getWrapperTypes();

    public static boolean isWrapperType(Class<?> clazz)
    {
        return WRAPPER_TYPES.contains(clazz);
    }

    private static Set<Class<?>> getWrapperTypes()
    {
        Set<Class<?>> ret = new HashSet<Class<?>>();
        ret.add(Boolean.class);
        ret.add(Character.class);
        ret.add(Byte.class);
        ret.add(Short.class);
        ret.add(Integer.class);
        ret.add(Long.class);
        ret.add(Float.class);
        ret.add(Double.class);
        ret.add(Void.class);
        return ret;
    }
}

You just need to name the anonymous property the same on both sides

on new { t1.ProjectID, SecondProperty = true } equals 
   new { t2.ProjectID, SecondProperty = t2.Completed } into j1

Based on the comments of @svick, here is another implementation that might make more sense:

from t1 in Projects
from t2 in Tasks.Where(x => t1.ProjectID == x.ProjectID && x.Completed == true)
                .DefaultIfEmpty()
select new { t1.ProjectName, t2.TaskName }

     CASE
     WHEN col IS NULL
        THEN ''
     ELSE SUBSTRING(col,1,15)+ '...' 
     END AS Col

Thanks everyone who helped. After doing some research myself (I'm the guy who asked the question), here is what I found to make sense most:

• Database column type: the timezone-agnostic number of milliseconds since 1970 represented as decimal(20) because 2^64 has 20 digits and disk space is cheap; let's be straightforward. Also, I will use neither DEFAULT CURRENT_TIMESTAMP, nor triggers. I want no magic in the DB.

• Java field type: long. The Unix timestamp is well supported across various libs, long has no Y2038 problems, timestamp arithmetic is fast and easy (mainly operator < and operator +, assuming no days/months/years are involved in the calculations). And, most importantly, both primitive longs and java.lang.Longs are immutable—effectively passed by value—unlike java.util.Dates; I'd be really pissed off to find something like foo.getLastUpdate().setTime(System.currentTimeMillis()) when debugging somebody else's code.

• The ORM framework should be responsible for filling in the data automatically.

• I haven't tested this yet, but only looking at the docs I assume that @Temporal will do the job; not sure about whether I might use @Version for this purpose. @PrePersist and @PreUpdate are good alternatives to control that manually. Adding that to the layer supertype (common base class) for all entities, is a cute idea provided that you really want timestamping for all of your entities.

jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div (or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.

Instead of override you can add another class to the element and then you have an extra abilities. for example:

HTML

<div class="style1 style2"></div>

CSS

//only style for the first stylesheet
.style1 {
   width: 100%;      
}
//only style for second stylesheet
.style2 {
   width: 50%;     
}
//override all
.style1.style2 { 
   width: 70%;
}

Scala

Scala evolved out of a pure functional language known as Funnel and represents a clean-room implementation of almost all Java's syntax, differing only where a clear improvement could be made or where it would compromise the functional nature of the language. Such differences include singleton objects instead of static methods, and type inference.

Much of this was based on Martin Odersky's prior work with the Pizza language. The OO/FP integration goes far beyond mere closures and has led to the language being described as post-functional.

Despite this, it's the closest to Java in many ways. Mainly due to a combination of OO support and static typing, but also due to a explicit goal in the language design that it should integrate very tightly with Java.

Groovy

Groovy explicitly tackles two of Java's biggest criticisms by

• being dynamically typed, which removes a lot of boilerplate and
• adding closures to the language.

It's perhaps syntactically closest to Java, not offering some of the richer functional constructs that Clojure and Scala provide, but still offering a definite evolutionary improvement - especially for writing script-syle programs.

Groovy has the strongest commercial backing of the three languages, mostly via springsource.

Clojure

Clojure is a functional language in the LISP family, it's also dynamically typed.

Features such as STM support give it some of the best out-of-the-box concurrency support, whereas Scala requires a 3rd-party library such as Akka to duplicate this.

Syntactically, it's also the furthest of the three languages from typical Java code.

I also have to disclose that I'm most acquainted with Scala :)

It should work with most VCS (depending on other criteria you might choose SVN, CVS, Darcs, TFS, etc), however it will actually the complete file (because it is a binary format), meaning that the "what changed" question is not so easy to answer.

You can still rely on log messages if people complete them, but you might also try the new XML based formats from Office 2007 to gain some more visibility (although it would still be hard to weed through the tons of XML, plus AFAIK the XML file is zipped on the disk, so you would need a pre-commit hook to unzip it for text diff to work correctly).

You are using the correct API, but is the "marker" variable visible to the entire script. I don't see this marker variable declared globally.

This is a simple way to select an option from a dropdownlist based on a string val

private void SetDDLs(DropDownList d,string val)
    {
        ListItem li;
        for (int i = 0; i < d.Items.Count; i++)
        {
            li = d.Items[i];
            if (li.Value == val)
            {
                d.SelectedIndex = i;
                break;
            }
        }
    }

Also doesn't work with

<TextBlock><TextBlock.Text>NO USING ABOVE TECHNIQUE HERE</TextBlock.Text>

No big deal, just needed to use

<TextBlock Text="Cool &#x0a;Newline trick" />

instead.

in my case I have used - (Hyphen) in my script name in case of Jenkinsfile Library. Got resolved after replacing Hyphen(-) with Underscore(_)

you can use a stackLayout, inside of this layout you can put a list a frame, for example:

<StackLayout VerticalOptions="FillAndExpand">
            <ListView  ItemsSource="{Binding YourList}"
                       CachingStrategy="RecycleElement"
                       HasUnevenRows="True">

                <ListView.ItemTemplate>
                    <DataTemplate>
                        <ViewCell >
                            <StackLayout  Orientation="Horizontal">
                                <Label Text="{Binding Image, Mode=TwoWay}" />

                            </StackLayout>
                        </ViewCell>
                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>
            <Frame BackgroundColor="AliceBlue" HorizontalOptions="FillAndExpand">
                <Button Text="More"></Button>
            </Frame>
        </StackLayout>

this is the result:

Yes, it is called Inline CSS, Here you styling the div using some height, width, and background.

Here the example:

<div style="width:50px;height:50px;background color:red">

You can achieve same using Internal or External CSS

2.Internal CSS:

  <head>
    <style>
    div {
    height:50px;
    width:50px;
    background-color:red;
    foreground-color:white;
    }
    </style>
  </head>
  <body>
    <div></div>
  </body>

3.External CSS:

<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<div></div>
</body>

style.css /external css file/

 div {
        height:50px;
        width:50px;
        background-color:red;
    }

The solution of @Chrispix is dangerous! Trusting all certificates allows anybody to do a man in the middle attack! Just send ANY certificate to the client and it will accept it!

Add your certificate(s) to a custom trust manager like described in this post: Trusting all certificates using HttpClient over HTTPS

Although it is a bit more complex to establish a secure connection with a custom certificate, it will bring you the wanted ssl encryption security without the danger of man in the middle attack!

In C++11, you can do this as a one-liner with a call to regex_replace:

#include <string>
#include <regex>

using std::string;

string do_replace( string const & in, string const & from, string const & to )
{
  return std::regex_replace( in, std::regex(from), to );
}

string test = "Remove all spaces";
std::cout << do_replace(test, " ", "") << std::endl;

output:

Removeallspaces

You can use "+" for returning extend, instead of extending in place.

l1=range(10)

l1+[11]

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11]

l2=range(10,1,-1)

l1+l2

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 9, 8, 7, 6, 5, 4, 3, 2]

Similarly += for in place behavior, but with slight differences from append & extend. One of the biggest differences of += from append and extend is when it is used in function scopes, see this blog post.

This is a followup to the font-forge section of @Kurt Pfeifle's answer, specific to Red Hat (and possibly other Linux distros).

1. After opening the PDF and selecting the font you want, you will want to select "File -> Generate Fonts..." option.
2. If there are errors in the file, you can choose to ignore them or save the file and edit them. Most of the errors can be fixed automatically if you click "Fix" enough times.
3. Click "Element -> Font Info...", and "Fontname", "Family Name" and "Name for Humans" are all set to values you like. If not, modify them and save the file somewhere. These names will determine how your font appears on the system.
4. Select your file name and click "Save..."

Once you have your TTF file, you can install it on your system by

1. Copying it to folder /usr/share/fonts (as root)
2. Running fc-cache -f /usr/share/fonts/ (as root)

From the Fragment documentation:

Often you will want one Fragment to communicate with another, for example to change the content based on a user event. All Fragment-to-Fragment communication is done through the associated Activity. Two Fragments should never communicate directly.

So I suggest you have look on the basic fragment training docs in the documentation. They're pretty comprehensive with an example and a walk-through guide.

You error clearly says, you are trying to use locale something was not there.

>>> locale.setlocale(locale.LC_ALL, 'de_DE')
Traceback (most recent call last):

  File "/usr/lib/python2.7/locale.py", line 581, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting

locale.Error: unsupported locale setting

To check available setting, use locale -a

deb@deb-Latitude-E7470:/ambot$ locale -a

C.UTF-8
en_AG
en_AG.utf8
en_AU.utf8
en_BW.utf8

en_NZ.utf8
en_PH.utf8
en_SG.utf8
en_US.utf8
en_ZA.utf8
en_ZM

POSIX

so you can use one among,

>>> locale.setlocale(locale.LC_ALL, 'en_AG.utf8')
'en_AG.utf8'
>>> 

for de_DE

This file can either be adjusted manually or updated using the tool, update-locale.

update-locale LANG=de_DE.UTF-8

As mentioned by @Brent in the comment of @maxymoo's answer, you can try

df.limit(10).toPandas()

to get a prettier table in Jupyter. But this can take some time to run if you are not caching the spark dataframe. Also, .limit() will not keep the order of original spark dataframe.

SHOULD GIVE YOU SOMETHING LIKE THIS

I would not recomend you to use document.write as others suggest, because if you will open such window twice your HTML will be duplicated 2 times (or more).

Use innerHTML instead

var win = window.open("", "Title", "toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=780,height=200,top="+(screen.height-400)+",left="+(screen.width-840));
win.document.body.innerHTML = "HTML";

As far as I understand you need mean terminate as Thread.Abort() right? In this case, you can just exit the Foo(). Or you can use Process to catch the thread.

Thread myThread = new Thread(DoWork);

myThread.Abort();

myThread.Start(); 

Process example:

using System;
using System.Diagnostics;
using System.ComponentModel;
using System.Threading;
using Microsoft.VisualBasic;

class PrintProcessClass
{

    private Process myProcess = new Process();
    private int elapsedTime;
    private bool eventHandled;

    // Print a file with any known extension.
    public void PrintDoc(string fileName)
    {

        elapsedTime = 0;
        eventHandled = false;

        try
        {
            // Start a process to print a file and raise an event when done.
            myProcess.StartInfo.FileName = fileName;
            myProcess.StartInfo.Verb = "Print";
            myProcess.StartInfo.CreateNoWindow = true;
            myProcess.EnableRaisingEvents = true;
            myProcess.Exited += new EventHandler(myProcess_Exited);
            myProcess.Start();

        }
        catch (Exception ex)
        {
            Console.WriteLine("An error occurred trying to print \"{0}\":" + "\n" + ex.Message, fileName);
            return;
        }

        // Wait for Exited event, but not more than 30 seconds.
        const int SLEEP_AMOUNT = 100;
        while (!eventHandled)
        {
            elapsedTime += SLEEP_AMOUNT;
            if (elapsedTime > 30000)
            {
                break;
            }
            Thread.Sleep(SLEEP_AMOUNT);
        }
    }

    // Handle Exited event and display process information.
    private void myProcess_Exited(object sender, System.EventArgs e)
    {

        eventHandled = true;
        Console.WriteLine("Exit time:    {0}\r\n" +
            "Exit code:    {1}\r\nElapsed time: {2}", myProcess.ExitTime, myProcess.ExitCode, elapsedTime);
    }

    public static void Main(string[] args)
    {

        // Verify that an argument has been entered.
        if (args.Length <= 0)
        {
            Console.WriteLine("Enter a file name.");
            return;
        }

        // Create the process and print the document.
        PrintProcessClass myPrintProcess = new PrintProcessClass();
        myPrintProcess.PrintDoc(args[0]);
    }
}

This is a hack to make inner functions (functions defined inside other functions) work more like they should. In javascript when you define one function inside another this automatically gets set to the global scope. This can be confusing because you expect this to have the same value as in the outer function.

var car = {};
car.starter = {};

car.start = function(){
    var that = this;

    // you can access car.starter inside this method with 'this'
    this.starter.active = false;

    var activateStarter = function(){
        // 'this' now points to the global scope
        // 'this.starter' is undefined, so we use 'that' instead.
        that.starter.active = true;

        // you could also use car.starter, but using 'that' gives
        // us more consistency and flexibility
    };

    activateStarter();

};

This is specifically a problem when you create a function as a method of an object (like car.start in the example) then create a function inside that method (like activateStarter). In the top level method this points to the object it is a method of (in this case, car) but in the inner function this now points to the global scope. This is a pain.

Creating a variable to use by convention in both scopes is a solution for this very general problem with javascript (though it's useful in jquery functions, too). This is why the very general sounding name that is used. It's an easily recognizable convention for overcoming a shortcoming in the language.

Like El Ronnoco hints at Douglas Crockford thinks this is a good idea.

A generic way to get a parent of a control that I have used is:

public static T GetParentOfType<T>(this Control control)
{
    const int loopLimit = 100; // could have outside method
    var current = control;
    var i = 0;

    do
    {
        current = current.Parent;

        if (current == null) throw new Exception("Could not find parent of specified type");
        if (i++ > loopLimit) throw new Exception("Exceeded loop limit");

    } while (current.GetType() != typeof(T));

    return (T)Convert.ChangeType(current, typeof(T));
}

It needs a bit of work (e.g. returning null if not found or error) ... but hopefully could help someone.

Usage:

var parent = currentControl.GetParentOfType<TypeWanted>();

Enjoy!

Hi not an expert in streaming but my understanding is that it is included in th Java Media Framework JMF http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/support-rtsp.html

And I have created the model scope

More about scopes:

• https://laravel.com/docs/5.8/eloquent#query-scopes

• https://medium.com/@janaksan_/using-scope-with-laravel-7c80dd6a2c3d

Code:

   /**
     * Scope a query to only include the last n days records
     *
     * @param  \Illuminate\Database\Eloquent\Builder $query
     * @return \Illuminate\Database\Eloquent\Builder
     */
    public function scopeWhereDateBetween($query,$fieldName,$fromDate,$todate)
    {
        return $query->whereDate($fieldName,'>=',$fromDate)->whereDate($fieldName,'<=',$todate);
    }

And in the controller, add the Carbon Library to top

use Carbon\Carbon;

OR

use Illuminate\Support\Carbon;

To get the last 10 days record from now

 $lastTenDaysRecord = ModelName::whereDateBetween('created_at',(new Carbon)->subDays(10)->toDateString(),(new Carbon)->now()->toDateString() )->get();

To get the last 30 days record from now

 $lastTenDaysRecord = ModelName::whereDateBetween('created_at',(new Carbon)->subDays(30)->toDateString(),(new Carbon)->now()->toDateString() )->get();

I realize this question was asked and answered a long time ago, but the answers don't give what I feel is the simplest solution. It's almost always a good idea to avoid loops whenever possible, and matplotlib's plot is capable of plotting multiple lines with one command. If x and y are arrays, then plot draws one line for every column.

In your case, you can do the following:

x=np.array([-1 ,0.5 ,1,-0.5])
xx = np.vstack([x[[0,2]],x[[1,3]]])
y=np.array([ 0.5,  1, -0.5, -1])
yy = np.vstack([y[[0,2]],y[[1,3]]])
plt.plot(xx,yy, '-o')

Have a long list of x's and y's, and want to connect adjacent pairs?

xx = np.vstack([x[0::2],x[1::2]])
yy = np.vstack([y[0::2],y[1::2]])

Want a specified (different) color for the dots and the lines?

plt.plot(xx,yy, '-ok', mfc='C1', mec='C1')

If this is for something that will be called a lot in an application instance, it's a lot faster to compile and cache dynamic code instead of using the activator or ConstructorInfo.Invoke(). Two easy options for dynamic compilation are compiled Linq Expressions or some simple IL opcodes and DynamicMethod. Either way, the difference is huge when you start getting into tight loops or multiple calls.

^((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)(\\.)){3}+((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?))$

Above will be regex for the ip address like: 221.234.000.112 also for 221.234.0.112, 221.24.03.112, 221.234.0.1

You can imagine all kind of address as above

string path = AppDomain.CurrentDomain.GetData("DataDirectory").ToString();

This is probably a more "correct" way of getting it.

I met the same problem as you.

I push two tables result into t1 object and group t1.

 from p in Products                         
  join bp in BaseProducts on p.BaseProductId equals bp.Id
  select new {
   p,
   bp
  } into t1
 group t1 by t1.p.SomeId into g
 select new ProductPriceMinMax { 
  SomeId = g.FirstOrDefault().p.SomeId, 
  CountryCode = g.FirstOrDefault().p.CountryCode, 
  MinPrice = g.Min(m => m.bp.Price), 
  MaxPrice = g.Max(m => m.bp.Price),
  BaseProductName = g.FirstOrDefault().bp.Name
};

Another one, it is an older project but shares the complete source code: http://telnetcsharp.codeplex.com/

Might be a little too late to the party, but hope this helps someone with similar issue.

The reason why your default value doesnt't work is because the migration file sets up the default value in your database (MySQL or PostgreSQL or whatever), and not in your Laravel application.

Let me illustrate with an example.

This line means Laravel is generating a new Book instance, as specified in your model. The new Book object will have properties according to the table associated with the model. Up until this point, nothing is written on the database.

$book = new Book();

Now the following lines are setting up the values of each property of the Book object. Same still, nothing is written on the database yet.

$book->author = 'Test'
$book->title = 'Test'

This line is the one writing to the database. After passing on the object to the database, then the empty fields will be filled by the database (may be default value, may be null, or whatever you specify on your migration file).

$book->save();

And thus, the default value will not pop up before you save it to the database.

But, that is not enough. If you try to access $book->price, it will still be null (or 0, i'm not sure). Saving it is only adding the defaults to the record in the database, and it won't affect the Object you are carrying around.

So, to get the instance with filled-in default values, you have to re-fetch the instance. You may use the

Book::find($book->id);

Or, a more sophisticated way by refreshing the instance

$book->refresh();

And then, the next time you try to access the object, it will be filled with the default values.

I found a bug on Mahoor13 answer, it's not working in loop so I've fixed it with this correction:

HTML:

<input type="email" id="eid" name="email_field" oninput="check(this)">

Javascript:

function check(input) {  
    if(input.validity.typeMismatch){  
        input.setCustomValidity("Dude '" + input.value + "' is not a valid email. Enter something nice!!");  
    }  
    else {  
        input.setCustomValidity("");  
    }                 
}  

It will perfectly running in loop.

This is how I do it.

try:
    do_something()
except:
    # How can I log my exception here, complete with its traceback?
    import traceback
    traceback.format_exc() # this will print a complete trace to stout.

Use dict.setdefault():

>>> d = {1: 'one'}
>>> d.setdefault(1, '1')
'one'
>>> d    # d has not changed because the key already existed
{1: 'one'}
>>> d.setdefault(2, 'two')
'two'
>>> d
{1: 'one', 2: 'two'}

CSS:

     .container div{
 width: 33.33%;
 float: left;
 height: 100px ;} 

Clear floats after the columns

 .container:after {
 content: "";
 display: table;
 clear: both;}

I assume you are using the caption feature of Word, that is, captions were not typed in as normal text, but were inserted using Insert > Caption (Word versions before 2007), or References > Insert Caption (in the ribbon of Word 2007 and up). If done correctly, the captions are really 'fields'. You'll know if it is a field if the caption's background turns grey when you put your cursor on them (or is permanently displayed grey).

Captions are fields - Unfortunately fields (like caption fields) are only updated on specific actions, like opening of the document, printing, switching from print view to normal view, etc. The easiest way to force updating of all (caption) fields when you want it is by doing the following:

1. Select all text in your document (easiest way is to press ctrl-a)
2. Press F9, this command tells Word to update all fields in the selection.

Captions are normal text - If the caption number is not a field, I am afraid you'll have to edit the text manually.

I did something like that:

HTML:

<p class='parent'>text text text</p>
<img class='child' src='idk.png'>

CSS:

.child {
    visibility: hidden;
}

.parent:hover .child {
    visibility: visible;
}

If you're not sure whether the object has been disposed or not, you should call the Dispose method itself rather than methods such as Close. While the framework doesn't guarantee that the Dispose method must run without exceptions even if the object had previously been disposed, it's a common pattern and to my knowledge implemented on all disposable objects in the framework.

The typical pattern for Dispose, as per Microsoft:

public void Dispose() 
{
    Dispose(true);

    // Use SupressFinalize in case a subclass
    // of this type implements a finalizer.
    GC.SuppressFinalize(this);      
}

protected virtual void Dispose(bool disposing)
{
    // If you need thread safety, use a lock around these 
    // operations, as well as in your methods that use the resource.
    if (!_disposed)
    {
        if (disposing) {
            if (_resource != null)
                _resource.Dispose();
                Console.WriteLine("Object disposed.");
        }

        // Indicate that the instance has been disposed.
        _resource = null;
        _disposed = true;   
    }
}

Notice the check on _disposed. If you were to call a Dispose method implementing this pattern, you could call Dispose as many times as you wanted without hitting exceptions.

The "nav nav-list" class of Twiter Bootstrap 2.0 is handy for building a side bar.

You can see a lot of documentation at http://www.w3resource.com/twitter-bootstrap/nav-tabs-and-pills-tutorial.php

Do this:

list(map(chr,[66,53,0,94]))

In Python 3+, many processes that iterate over iterables return iterators themselves. In most cases, this ends up saving memory, and should make things go faster.

If all you're going to do is iterate over this list eventually, there's no need to even convert it to a list, because you can still iterate over the map object like so:

# Prints "ABCD"
for ch in map(chr,[65,66,67,68]):
    print(ch)

Once you have decoded the JSON, the result is a JavaScript object. Just manipulate it as you would any other object. For example:

data.busNum = 12345;
...

In your custom view pager adapter, override those methods in ViewPager.

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    // Never allow swiping to switch between pages
    return false;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    // Never allow swiping to switch between pages
    return false;
}

And to enable, just return each super method:

super.onInterceptTouchEvent(event) and super.onTouchEvent(event).

import class folder does not work for me, but add jar worked!

1. put the class folder under the project folder

2. Zip the class folder

3. Highlight project name, click "Project" in the top toolbar, click "Properties", click "Libraries" tab, click "Add External jars".

4. Add the zip file. Done!

If you don't mind using lodash try out https://github.com/rockabox/ng-lodash it wraps lodash completely so it is the only dependency and you don't need to load any other script files such as lodash.

Lodash is completely off of the window scope and no "hoping" that it's been loaded prior to your module.

I had problems due to atom being unable to write its logfile when starting from the commandline. This cured it.

sudo chmod 777 ~/.atom/nohup.out

Apart from what Andy mentioned, there is another difference which could be important - write-host directly writes to the host and return nothing, meaning that you can't redirect the output, e.g., to a file.

---- script a.ps1 ----
write-host "hello"

Now run in PowerShell:

PS> .\a.ps1 > someFile.txt
hello
PS> type someFile.txt
PS>

As seen, you can't redirect them into a file. This maybe surprising for someone who are not careful.

But if switched to use write-output instead, you'll get redirection working as expected.

I believe you are getting an empty array because PHP is expecting the posted data to be in a Querystring format (key=value&key1=value1).

Try changing your curl request to:

curl -i -X POST -d 'json={"screencast":{"subject":"tools"}}'  \
      http://localhost:3570/index.php/trainingServer/screencast.json

and see if that helps any.

1. Make the servlet filter implement the spring Ordered interface.
2. Declare the servlet filter bean manually in configuration class.

    import org.springframework.core.Ordered;
    
    public class MyFilter implements Filter, Ordered {

        @Override
        public void init(FilterConfig filterConfig) {
            // do something
        }

        @Override
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
            // do something
        }

        @Override
        public void destroy() {
            // do something
        }

        @Override
        public int getOrder() {
            return -100;
        }
    }


    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.context.annotation.Configuration;

    @Configuration
    @ComponentScan
    public class MyAutoConfiguration {

        @Bean
        public MyFilter myFilter() {
            return new MyFilter();
        }
    }

Use something like this:

page1.php

<?php
session_start();
$_SESSION['myValue']=3; // You can set the value however you like.
?>

Any other PHP page:

<?php
session_start();
echo $_SESSION['myValue'];
?>

A few notes to keep in mind though: You need to call session_start() BEFORE any output, HTML, echos - even whitespace.

You can keep changing the value in the session - but it will only be able to be used after the first page - meaning if you set it in page 1, you will not be able to use it until you get to another page or refresh the page.

The setting of the variable itself can be done in one of a number of ways:

$_SESSION['myValue']=1;
$_SESSION['myValue']=$var;
$_SESSION['myValue']=$_GET['YourFormElement'];

And if you want to check if the variable is set before getting a potential error, use something like this:

if(!empty($_SESSION['myValue'])
{
    echo $_SESSION['myValue'];
}
else
{
    echo "Session not set yet.";
}

in bash, replace N,M by the line numbers and xxx yyy by what you want

i=1
while read line;do
  if((i==N));then
    echo 'xxx'
  elif((i==M));then
    echo 'yyy'
  else
    echo "$line"
  fi
  ((i++))
done  < orig-file > new-file

EDIT

In fact in this solution there are some problems, with characters "\0" "\t" and "\"

"\t", can be solve by putting IFS= before read: "\", at end of line with -r

IFS= read -r line

but for "\0", the variable is truncated, there is no a solution in pure bash : Assign string containing null-character (\0) to a variable in Bash But in normal text file there is no nul character \0

perl would be a better choice

perl -ne 'if($.==N){print"xxx\n"}elsif($.==M){print"yyy\n"}else{print}' < orig-file > new-file

I found this post in google as the second top result, first was using exec :(

Anyway, while this did not suite my needs exactly.. I decided to post an answer for others with my quick but extended version of this.

SCRIPT FEATURES

• Backup file naming day by day, PREFIX-YYYY-MM-DD-POSTFIX.EXTENSION
• File Reporting / Missing
• Previous Backups Listing
• Does not zip / include previous backups ;)
• Works on windows/linux

Anyway, onto the script.. While it may look like a lot.. Remember there is excess in here.. So feel free to delete the reporting sections as needed...

Also it may look messy as well and certain things could be cleaned up easily... So dont comment about it, its just a quick script with basic comments thrown in.. NOT FOR LIVE USE.. But easy to clean up for live use!

In this example, it is run from a directory that is inside of the root www / public_html folder.. So only needs to travel up one folder to get to the root.

<?php
    // DIRECTORY WE WANT TO BACKUP
    $pathBase = '../';  // Relate Path

    // ZIP FILE NAMING ... This currently is equal to = sitename_www_YYYY_MM_DD_backup.zip 
    $zipPREFIX = "sitename_www";
    $zipDATING = '_' . date('Y_m_d') . '_';
    $zipPOSTFIX = "backup";
    $zipEXTENSION = ".zip";

    // SHOW PHP ERRORS... REMOVE/CHANGE FOR LIVE USE
    ini_set('display_errors',1);
    ini_set('display_startup_errors',1);

WHAT DOES IT DO??

It will simply zip the complete contents of the variable $pathBase and store the zip in that same folder. It does a simple detection for previous backups and skips them.

CRON BACKUP

This script i've just tested on linux and worked fine from a cron job with using an absolute url for the pathBase.

For those wanting to use a Class.

Create a Class with all the parameters you want

Create a list with the class as parameter

class MyClass_x000D_
        {_x000D_
            public string S1;_x000D_
            public string S2;_x000D_
        }_x000D_
_x000D_
List<MyClass> MyList= new List<MyClass>();

If all your rows are the same height, just set the rowHeight property of the UITableView rather than implementing the heightForRowAtIndexPath. Apple Docs:

There are performance implications to using tableView:heightForRowAtIndexPath: instead of rowHeight. Every time a table view is displayed, it calls tableView:heightForRowAtIndexPath: on the delegate for each of its rows, which can result in a significant performance problem with table views having a large number of rows (approximately 1000 or more).

Here's a performant and simple function I created (which uses basic string validation before using json_decode for larger strings):

function isJson($string) {
    $response = false;

    if (
        is_string($string) &&
        ($string = trim($string)) &&
        ($stringLength = strlen($string)) &&
        (
            (
                stripos($string, '{') === 0 &&
                (stripos($string, '}', -1) + 1) === $stringLength
            ) ||
            (
                stripos($string, '[{') === 0 &&
                (stripos($string, '}]', -1) + 2) === $stringLength
            )
        ) &&
        ($decodedString = json_decode($string, true)) &&
        is_array($decodedString)
    ) {
        $response = true;
    }

    return $response;
}

I was stuck in this as I was using it in a loop for finding elements and adding listner to it. If you're using it in a loop, then this will work perfectly

for (var i = 0; i < states_array.length; i++) {
     var link = document.getElementById('apply_'+states_array[i].state_id);
     link.my_id = i;
     link.addEventListener('click', function(e) {   
        alert(e.target.my_id);        
        some_function(states_array[e.target.my_id].css_url);
     });
}

I would suggest doing this in a more functional style :P

function CreateMessageboard(BoardMessages) {
  var htmlMessageboardString = BoardMessages
   .map(function(BoardMessage) {
     return MessageToHTMLString(BoardMessage);
   })
   .join('');
}

Try this

for each project in your solution make sure that

Properties > Config. Properties > General > Platform Toolset

is one for all of them, v100 for visual studio 2010, v110 for visual studio 2012

you also may be working on v100 from visual studio 2012

The accepted answer needs an Option 3

ALSO Option 2 is TERRIBLE. It should NEVER be used (esp. in production) since it provides a FALSE sense of security. Just use HTTP instead of Option 2.

There is no solution for this within the .net framework.

http://www.eldos.com/sbb/sftpcompare.php outlines a list of un-free options.

your best free bet is to extend SSH using Granados. http://www.routrek.co.jp/en/product/varaterm/granados.html

You should look at the members of the thrown exception, particularly .Message and .InnerException.

I would also see whether or not the documentation for InvokeMethod tells you whether it throws some more specialized Exception class than Exception - such as the Win32Exception suggested by @Preet. Catching and just looking at the Exception base class may not be particularly useful.

The MacGyver way,just for lulz

var a = [80, 77, 88, 95, 68];_x000D_
_x000D_
console.log(eval(a.join('+'))/a.length)

A simple, although awk-less solution in bash:

while IFS=, read -r a a a b; do echo "$a"; done <inputfile

It works faster for small files (<100 lines) then awk as it uses less resources (avoids calling the expensive fork and execve system calls).

EDIT from Ed Morton (sorry for hi-jacking the answer, I don't know if there's a better way to address this):

To put to rest the myth that shell will run faster than awk for small files:

$ wc -l file
99 file

$ time while IFS=, read -r a a a b; do echo "$a"; done <file >/dev/null

real    0m0.016s
user    0m0.000s
sys     0m0.015s

$ time awk -F, '{print $3}' file >/dev/null

real    0m0.016s
user    0m0.000s
sys     0m0.015s

I expect if you get a REALY small enough file then you will see the shell script run in a fraction of a blink of an eye faster than the awk script but who cares?

And if you don't believe that it's harder to write robust shell scripts than awk scripts, look at this bug in the shell script you posted:

$ cat file
a,b,-e,d
$ cut -d, -f3 file
-e
$ awk -F, '{print $3}' file
-e
$ while IFS=, read -r a a a b; do echo "$a"; done <file

How to install PyQt4 on anaconda python 2 on Windows:

At first I have tried to isntall pyqt4 via pip install:

C:\Users\myuser\Anaconda2\Scripts\pip.exe search pyqt4 > pyqt4.txt

It shows:

And finnaly it works!

You can try with below one:

  <div style="width: 100%; height: 100%; overflow-x: visible; overflow-y: scroll;">Text</div>

Max length will not work with <input type="number" the best way i know is to use oninput event to limit the maxlength. Please see the below code.

<input name="somename"
    oninput="javascript: if (this.value.length > this.maxLength) this.value = this.value.slice(0, this.maxLength);"
    type = "number"
    maxlength = "6"
 />

|= reads the same way as +=.

notification.defaults |= Notification.DEFAULT_SOUND;

is the same as

notification.defaults = notification.defaults | Notification.DEFAULT_SOUND;

where | is the bit-wise OR operator.

All operators are referenced here.

A bit-wise operator is used because, as is frequent, those constants enable an int to carry flags.

If you look at those constants, you'll see that they're in powers of two :

public static final int DEFAULT_SOUND = 1;
public static final int DEFAULT_VIBRATE = 2; // is the same than 1<<1 or 10 in binary
public static final int DEFAULT_LIGHTS = 4; // is the same than 1<<2 or 100 in binary

So you can use bit-wise OR to add flags

int myFlags = DEFAULT_SOUND | DEFAULT_VIBRATE; // same as 001 | 010, producing 011

so

myFlags |= DEFAULT_LIGHTS;

simply means we add a flag.

And symmetrically, we test a flag is set using & :

boolean hasVibrate = (DEFAULT_VIBRATE & myFlags) != 0;

You can use nonzero function. it returns the nonzero indices of the given input.

Easy Way

>>> (e > 15).nonzero()

(array([1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]), array([6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9]))

to see the indices more cleaner, use transpose method:

>>> numpy.transpose((e>15).nonzero())

[[1 6]
 [1 7]
 [1 8]
 [1 9]
 [2 0]
 ...

Not Bad Way

>>> numpy.nonzero(e > 15)

(array([1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]), array([6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9]))

or the clean way:

>>> numpy.transpose(numpy.nonzero(e > 15))

[[1 6]
 [1 7]
 [1 8]
 [1 9]
 [2 0]
 ...

Open Notepad and write this

@echo off
:A
Cls
echo MESSENGER
set /p n=User:
set /p m=Message:
net send %n% %m%
Pause
Goto A

and then save as "Messenger.bat" and close the Notepad
Step 1:

when you open that saved notepad file it will open as a file Messenger command prompt with this details.

Messenger
User:

after "User" write the ip of the computer you want to contact and then press enter.

The WITH clause for Common Table Expressions go at the top.

Wrapping every insert in a CTE has the benefit of visually segregating the query logic from the column mapping.

Spot the mistake:

WITH _INSERT_ AS (
  SELECT
    [BatchID]      = blah
   ,[APartyNo]     = blahblah
   ,[SourceRowID]  = blahblahblah
  FROM Table1 AS t1
)
INSERT Table2
      ([BatchID], [SourceRowID], [APartyNo])
SELECT [BatchID], [APartyNo], [SourceRowID]   
FROM _INSERT_

Same mistake:

INSERT Table2 (
  [BatchID]
 ,[SourceRowID]
 ,[APartyNo]
)
SELECT
  [BatchID]      = blah
 ,[APartyNo]     = blahblah
 ,[SourceRowID]  = blahblahblah
FROM Table1 AS t1

A few lines of boilerplate make it extremely easy to verify the code inserts the right number of columns in the right order, even with a very large number of columns. Your future self will thank you later.

A neat trick I discovered is that if you go to "Add existing...", you can drag the folder from the open dialog to your solution.

I have my Visual Studio to open in Admin Mode automatically, so this was a good workaround for me as I didn't want to have to undo that just to get this to work.

One more related question, since it took me forever to find the answer:

How to make the legend background blank (i.e. transparent, not white):

legend = plt.legend()

Warning, you want 'none' (the string). None means the default color instead.

I too got same problem.

I was using span with in td like 03/21/2017, by doing this, datatable treated this as string and sorting did not work.

I removed span inside td, and it got fixed. like, 03/21/2017

There is a simple solution for you called unique_together which does exactly what you want.

For example:

class MyModel(models.Model):
  field1 = models.CharField(max_length=50)
  field2 = models.CharField(max_length=50)

  class Meta:
    unique_together = ('field1', 'field2',)

And in your case:

class Volume(models.Model):
  id = models.AutoField(primary_key=True)
  journal_id = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name = "Journal")
  volume_number = models.CharField('Volume Number', max_length=100)
  comments = models.TextField('Comments', max_length=4000, blank=True)

  class Meta:
    unique_together = ('journal_id', 'volume_number',)

You can use margin property with the bootstrap img class.

.name-of-class .img-responsive { margin: 0 auto; }

When you say the 'GUI Tool', I assume you're using Git For Windows.

IMPORTANT, I would highly recommend creating a new branch to do this on if you haven't already. That way your master can remain the same while you test out your changes.

With the GUI you need to 'roll back this commit' like you have with the history on the right of your view. Then you will notice you have all the unwanted files as changes to commit on the left. Now you need to right click on the grey title above all the uncommited files and select 'disregard changes'. This will set your files back to how they were in this version.

My problem was actually that my build was in Release mode instead of Debug mode. As a result, the identifier was pointing to something that was not in existence. I changed the build type and it ended up working.

For NPM => npm run Build For Yarn => yarn run build

You also can check scripts in package.json file

Maybe this is a no-brainer for the xslt-professional, but for me at beginner/intermediate level, this got me puzzled. I wanted to do exactly the same thing, but I had to test a responsetime value from an xml instead of a plain number. Following this thread, I tried this:

<xsl:when test="responsetime/@value &gt;= 5000 and responsetime/@value &lt;= 8999"> 

which generated an error. This works:

<xsl:when test="number(responsetime/@value) &gt;= 5000 and number(responsetime/@value) &lt;= 8999">

Don't really understand why it doesn't work without number(), though. Could it be that without number() the value is treated as a string and you can't compare numbers with a string?

Anyway, hope this saves someone a lot of searching...

You can use IETester (http://www.my-debugbar.com/wiki/IETester/HomePage)

You could have simply replaced

names[i] = in.nextLine(); with names[i] = in.next();

Using next() will only return what comes before a space. nextLine() automatically moves the scanner down after returning the current line.

select column1..... from table1
where column1=''
union
select column1..... from table2
where column1= ''

I had the same(?) problem. Couldn't get header column to display row header data (a simple row number) with my data bound grid. Once I moved the code to the event "DataBindingComplete" it worked.

Sorry for the extra code. I wanted to provide a working example but don't have time to cut it all down so just cut and pasted some of my app and fixed it up to run for you. Here you go:

using System;
using System.Collections.Generic;
using System.Data;
using System.Windows.Forms;
using System.Windows.Forms.DataVisualization.Charting;

namespace WindowsFormsApplication3
{
    public partial class Form1 : Form
    {
        private List<DataPoint> pts = new List<DataPoint>();

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            InsertPoint(10, 20);
            InsertPoint(12, 40);
            InsertPoint(16, 60);
            InsertPoint(20, 77);
            InsertPoint(92, 80);

            MakeGrid();
        }

        public void InsertPoint(int parameterValue, int commandValue)
        {
            DataPoint pt = new DataPoint();
            pt.XValue = commandValue;
            pt.YValues[0] = parameterValue;
            pts.Add(pt);
        }

        private void MakeGrid()
        {
            dgv1.SuspendLayout();
            DataTable dt = new DataTable();
            dt.Columns.Clear();
            dt.Columns.Add("Parameter");
            dt.Columns.Add("Command");

            //*** Add Data to DataTable
            for (int i = 0; i <= pts.Count - 1; i++)
            {
                dt.Rows.Add(pts[i].XValue, pts[i].YValues[0]);
            }
            dgv1.DataSource = dt;

            //*** Formatting for the grid is performed in event dgv1_DataBindingComplete.
            //*** If its performed here, the changes appear to get wiped in the grid control.
        }

        private void dgv1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
        {
            DataGridViewCellStyle style = new DataGridViewCellStyle();
            style.Alignment = DataGridViewContentAlignment.MiddleRight;

            //*** Add row number to each row
            foreach (DataGridViewRow row in dgv1.Rows)
            {
                row.HeaderCell.Value = (row.Index + 1).ToString();
                row.HeaderCell.Style = style;
                row.Resizable = DataGridViewTriState.False;
            }
            dgv1.ClearSelection();
            dgv1.CurrentCell = null;
            dgv1.ResumeLayout();

Updated Answer:

Since some of the classes, in the original answer, are deprecated in the newer version of Apache HTTP Components, I'm posting this update.

By the way, you can access the full documentation for more examples here.

HttpClient httpclient = HttpClients.createDefault();
HttpPost httppost = new HttpPost("http://www.a-domain.com/foo/");

// Request parameters and other properties.
List<NameValuePair> params = new ArrayList<NameValuePair>(2);
params.add(new BasicNameValuePair("param-1", "12345"));
params.add(new BasicNameValuePair("param-2", "Hello!"));
httppost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));

//Execute and get the response.
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();

if (entity != null) {
    try (InputStream instream = entity.getContent()) {
        // do something useful
    }
}

Original Answer:

I recommend to use Apache HttpClient. its faster and easier to implement.

HttpPost post = new HttpPost("http://jakarata.apache.org/");
NameValuePair[] data = {
    new NameValuePair("user", "joe"),
    new NameValuePair("password", "bloggs")
};
post.setRequestBody(data);
// execute method and handle any error responses.
...
InputStream in = post.getResponseBodyAsStream();
// handle response.

Since Python 3.5 you can unpack unlimited amount of lists.

PEP 448 - Additional Unpacking Generalizations

So this will work:

a = ['1', '2', '3', '4']
b = ['5', '6']
function_that_needs_strings(*a, *b)

foo.GetColumnValues(dm.mainColumn, typeof(int));
foo.GetColumnValues(dm.mainColumn, typeof(string));

Or using generics:

foo.GetColumnValues<int>(dm.mainColumn);
foo.GetColumnValues<string>(dm.mainColumn);

Example. To find number of vowels within the string

var word='Web Development Tutorial';
var vowels='[aeiou]'; 
var re = new RegExp(vowels, 'gi');
var arr = word.match(re);
document.write(arr.length);

I think you hit the same issue as discussed in this post. You forgot to escape your \ character.

Use:

if (function_exists('curl_file_create')) { // php 5.5+
  $cFile = curl_file_create($file_name_with_full_path);
} else { // 
  $cFile = '@' . realpath($file_name_with_full_path);
}
$post = array('extra_info' => '123456','file_contents'=> $cFile);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);

You can also refer:

http://blog.derakkilgo.com/2009/06/07/send-a-file-via-post-with-curl-and-php/

Important hint for PHP 5.5+:

Now we should use https://wiki.php.net/rfc/curl-file-upload but if you still want to use this deprecated approach then you need to set curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);

In my case (.Net Core Web API) for this issue HTTP Error 500.19 – Internal Server Error 0x8007000d

In Spring you can escape the html from JSP pages generated by <form> tags. This closes off a lot avenues for XSS attacks, and can be done automatically in three ways:

For the entire application in the web.xml file:

<context-param>
    <param-name>defaultHtmlEscape</param-name>
    <param-value>true</param-value>
</context-param>

For all forms on a given page in the file itself:

<spring:htmlEscape defaultHtmlEscape="true" /> 

For each form:

<form:input path="someFormField" htmlEscape="true" /> 

function selectText(containerid) {_x000D_
    if (document.selection) { // IE_x000D_
        var range = document.body.createTextRange();_x000D_
        range.moveToElementText(document.getElementById(containerid));_x000D_
        range.select();_x000D_
    } else if (window.getSelection) {_x000D_
        var range = document.createRange();_x000D_
        range.selectNode(document.getElementById(containerid));_x000D_
        window.getSelection().removeAllRanges();_x000D_
        window.getSelection().addRange(range);_x000D_
    }_x000D_
}

<div id="selectable" onclick="selectText('selectable')">http://example.com/page.htm</div>

Now you have to pass the ID as an argument, which in this case is "selectable", but it's more global, allowing you to use it anywhere multiple times without using, as chiborg mentioned, jQuery.

After combining the information in this thread with the R-help ?rect, I came up with this nice graph for circadian rhythm data (24h plot). The script for the background rectangles is this:

root script:

>rect(xleft, ybottom, xright, ytop, col = NA, border = NULL)

My script:

>i <- 24*(0:8)
>rect(8+i, 1, 24+i, 130, col = "lightgrey", border=NA)
>rect(8+i, -10, 24+i, 0.1, col = "black", border=NA)

The idea is to represent days of 24 hours with 8 h light and 16 h dark.

jQuery's delay function is meant to be used with effects and effect queues, see the delay docs and the example therein:

$('#foo').slideUp(300).delay(800).fadeIn(400);

If you want to observe a variable for changes, you could do something like

(function() {
    var observerInterval = setInterval(function() {
        if (/* check for changes here */) {
           clearInterval(observerInterval);
           // do something here
        }
    }, 1000);
})();

Do this :

$(document).ready(function(){
     $("#frm1").submit();
});

Fastest way is this :

    public static string GetHash(string input)
    {
        return string.Join("", (new SHA1Managed().ComputeHash(Encoding.UTF8.GetBytes(input))).Select(x => x.ToString("X2")).ToArray());
    }

For Small character output use x2 in replace of of X2

Many thanks to David Walsh, here is a vanilla version of underscore debounce.

Code:

// Returns a function, that, as long as it continues to be invoked, will not
// be triggered. The function will be called after it stops being called for
// N milliseconds. If `immediate` is passed, trigger the function on the
// leading edge, instead of the trailing.
function debounce(func, wait, immediate) {
    var timeout;
    return function() {
        var context = this, args = arguments;
        var later = function() {
            timeout = null;
            if (!immediate) func.apply(context, args);
        };
        var callNow = immediate && !timeout;
        clearTimeout(timeout);
        timeout = setTimeout(later, wait);
        if (callNow) func.apply(context, args);
    };
};

Simple usage:

var myEfficientFn = debounce(function() {
    // All the taxing stuff you do
}, 250);

$(window).on('resize', myEfficientFn);

Building on Jon Skeet's reply, there are times when you want to invoke a delegate and wait for its execution to complete before the current thread continues. In those cases the Invoke call is what you want.

In multi-threading applications, you may not want a thread to wait on a delegate to finish execution, especially if that delegate performs I/O (which could make the delegate and your thread block).

In those cases the BeginInvoke would be useful. By calling it, you're telling the delegate to start but then your thread is free to do other things in parallel with the delegate.

Using BeginInvoke increases the complexity of your code but there are times when the improved performance is worth the complexity.

• Debug: fine-grained statements concerning program state, typically used for debugging;

• Info: informational statements concerning program state, representing program events or behavior tracking;

• Warn: statements that describe potentially harmful events or states in the program;

• Error: statements that describe non-fatal errors in the application; this level is used quite often for logging handled exceptions;

• Fatal: statements representing the most severe of error conditions, assumedly resulting in program termination.

Have a look at https://developer.mozilla.org/En/Core_JavaScript_1.5_Reference/Global_Objects/Array for documentation on JavaScript Arrays.
jQuery is a library which adds some magic to JavaScript which is a capable and featurefull scripting language. The libraries just fill in the gaps - get to know the core!

From the documentation for strtotime():

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

In your date string, you have 12-16-2013. 16 isn't a valid month, and hence strtotime() returns false.

Since you can't use DateTime class, you could manually replace the - with / using str_replace() to convert the date string into a format that strtotime() understands:

$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16

If you're into RegEx....

var newURL = testURL.match(new RegExp("[^?]+"))

I hope to provide more background knowledge here.

First, constructor signature of the of method threading::Thread:

class threading.Thread(group=None, target=None, name=None, args=(), kwargs={}, *, daemon=None)

args is the argument tuple for the target invocation. Defaults to ().

Second, A quirk in Python about tuple:

Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses).

On the other hand, a string is a sequence of characters, like 'abc'[1] == 'b'. So if send a string to args, even in parentheses (still a sting), each character will be treated as a single parameter.

However, Python is so integrated and is not like JavaScript where extra arguments can be tolerated. Instead, it throws an TypeError to complain.

Use OnClicklistener or you can use android:onClick="myMethod" in your button's xml code from which you going to open a new layout. So when that button is clicked your myMethod function will be called automatically. Your myMethod function in class look like this.

public void myMethod(View v) {
Intent intent=new Intent(context,SecondActivty.class);
startActivity(intent);
}

And in that SecondActivity.class set new layout in contentview.

In case you use jQuery you need to wait for $(window).load, because the embedded SVG document might not be yet loaded at $(document).ready

$(window).load(function () {

    //alert("Document loaded, including graphics and embedded documents (like SVG)");
    var a = document.getElementById("alphasvg");

    //get the inner DOM of alpha.svg
    var svgDoc = a.contentDocument;

    //get the inner element by id
    var delta = svgDoc.getElementById("delta");
    delta.addEventListener("mousedown", function(){ alert('hello world!')}, false);
});

array1.equals(array2) is the same as array1 == array2, i.e. is it the same array. As @alf points out it's not what most people expect.

Arrays.equals(array1, array2) compares the contents of the arrays.

Similarly array.toString() may not be very useful and you need to use Arrays.toString(array).

A solution without the Desktop environment is BrowserLauncher2. This solution is more general as on Linux, Desktop is not always available.

The lenghty answer is posted at https://stackoverflow.com/a/21676290/873282

This works for me:

<style type="text/css">
    td {

        /* CSS 3 */
        white-space: -o-pre-wrap;
        word-wrap: break-word;
        white-space: pre-wrap;
        white-space: -moz-pre-wrap;
        white-space: -pre-wrap;
    }

And table attribute is:

   table {
      table-layout: fixed;
      width: 100%
   }

</style>

The command looks quite fine. Could you try to run -v (verbose mode) and then we can figure out what it is wrong on the authentication?

Also as mention in the other answer, maybe could be this issue - that you need to convert the keys (answered already here): How to convert SSH keypairs generated using PuttyGen(Windows) into key-pairs used by ssh-agent and KeyChain(Linux) OR http://winscp.net/eng/docs/ui_puttygen (depending what you need)

Try the -fno-stack-protector flag.

One of the common problems with VLOOKUP is "data mismatch" where #N/A is returned because a numeric lookup value doesn't match a text-formatted value in the VLOOKUP table (or vice versa)

Does either of these versions work?

=VLOOKUP(M3&"",Sheet1!$A$2:$Q$47,13,FALSE)

or

=VLOOKUP(M3+0,Sheet1!$A$2:$Q$47,13,FALSE)

The former converts a numeric lookup value to text (assuming that lookup table 1st column contains numbers formatted as text). The latter does the reverse, changing a text-formatted lookup value to a number.

Depending on which one works (assuming one does) then you may want to permanently change the format of your data so that the standard VLOOKUP will work

Why are you not using this?

int[] array = { 12, 56, 89, 65, 61, 36, 45, 23 };
int max = array.Max();
int min = array.Min();

One thing that you need to be aware of when reflecting on private members is that if your application is running in medium trust (as, for instance, when you are running on a shared hosting environment), it won't find them -- the BindingFlags.NonPublic option will simply be ignored.

How about less /var/log/syslog?

Simply changing the cable and Authorizing the Mac worked for me!

To convert an ordinal into its enum represantation you might want to do this:

ReportTypeEnum value = ReportTypeEnum.values()[ordinal];

Please notice the array bounds.

Note that every call to values() returns a newly cloned array which might impact performance in a negative way. You may want to cache the array if it's going to be called often.

This is a Python 101 type question,

It's a simple question but one where the answer is not so simple.

In python3, a "bytes" object represents a sequence of bytes, a "string" object represents a sequence of unicode code points.

To convert between from "bytes" to "string" and from "string" back to "bytes" you use the bytes.decode and string.encode functions. These functions take two parameters, an encoding and an error handling policy.

Sadly there are an awful lot of cases where sequences of bytes are used to represent text, but it is not necessarily well-defined what encoding is being used. Take for example filenames on unix-like systems, as far as the kernel is concerned they are a sequence of bytes with a handful of special values, on most modern distros most filenames will be UTF-8 but there is no gaurantee that all filenames will be.

If you want to write robust software then you need to think carefully about those parameters. You need to think carefully about what encoding the bytes are supposed to be in and how you will handle the case where they turn out not to be a valid sequence of bytes for the encoding you thought they should be in. Python defaults to UTF-8 and erroring out on any byte sequence that is not valid UTF-8.

print(bytesThing)

Python uses "repr" as a fallback conversion to string. repr attempts to produce python code that will recreate the object. In the case of a bytes object this means among other things escaping bytes outside the printable ascii range.

As mentioned here, https://stackoverflow.com/a/50941562/2186220, use gradle plugin version 3 or higher while using 'implementation'.

Also, use the google() repository in buildscript.

buildscript {
    repositories {
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

These changes should solve the issue.

You missed break statements. Don't forget to use break-statements even in the default case.

switch (searchType)
{
    case "SearchBooks":
        Selenium.Type("//*[@id='SearchBooks_TextInput']", searchText);
        Selenium.Click("//*[@id='SearchBooks_SearchBtn']");
        break;
    case "SearchAuthors":
        Selenium.Type("//*[@id='SearchAuthors_TextInput']", searchText);
        Selenium.Click("//*[@id='SearchAuthors_SearchBtn']");
        break;
    default:
        Console.WriteLine("Default case handling");
        break;
}

If you don't mind using OFFSET(), which is a volatile function that recalculates everytime a cell is changed, then this is a good solution that is both dynamic and reusable:

=OFFSET($COL:$COL, ROW(), 1, 1048576 - ROW(), 1)

where $COL is the letter of the column you are going to operate upon, and ROW() is the row function that dynamically selects the same row as the cell containing this formula. You could also replace the ROW() function with a static number ($ROW).

=OFFSET($COL:$COL, $ROW, 1, 1048576 - $ROW, 1)

You could further clean up the formula by defining a named constant for the 1048576 as 'maxRows'. This can be done in the 'Define Name' menu of the Formulas tab.

=OFFSET($COL:$COL, $ROW, 1, maxRows - $ROW, 1)

A quick example: to Sum from C6 to the end of column C, you could do:

=SUM(OFFSET(C:C, 6, 1, maxRows - 6, 1))

or =SUM(OFFSET(C:C, ROW(), 1, maxRows - ROW(),1))

Add this to your code for fixed height and add one scroll.

.fixedbox {
    max-height: auto;
    overflow-y: scroll;
}

In any .NET langauge, Environment.NewLine would be preferable.

The best to remove a class in jquery from all the elements is to target via element tag. e.g.,

$("div").removeClass("highlight");

I will leave this here as a possible fix, worked for me at least and might help others. Pretty sure this would be a linux only fix.

I decided to not go with the pip install and go with the github version (option one on the installation guide).

Instead of placing the copied docker-compose directory into /usr/local/bin/docker-compose from the curl/github command, I went with /usr/bin/docker-compose which is the location of Docker itself and will force the program to run in root. So it works in root and sudo but now won't work without sudo so the opposite effect which is what you want to run it as a user anyways.

ArrayAdapter uses a TextView to display each item within it. Behind the scenes, it uses the toString() method of each object that it holds and displays this within the TextView. ArrayAdapter has a number of constructors that can be used and the one that you have used in your example is:

ArrayAdapter(Context context, int resource, int textViewResourceId, T[] objects)

By default, ArrayAdapter uses the default TextView to display each item. But if you want, you could create your own TextView and implement any complex design you'd like by extending the TextView class. This would then have to go into the layout for your use. You could reference this in the textViewResourceId field to bind the objects to this view instead of the default.

For your use, I would suggest that you use the constructor:

ArrayAdapter(Context context, int resource, T[] objects). 

In your case, this would be:

ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, values)

and it should be fine. This will bind each string to the default TextView display - plain and simple white background.

So to answer your question, you do not have to use the textViewResourceId.

Here is an example

import numpy as np
import matplotlib.pyplot as plt

x = np.random.rand(100)
y = np.random.rand(100)
t = np.arange(100)

plt.scatter(x, y, c=t)
plt.show()

Here you are setting the color based on the index, t, which is just an array of [1, 2, ..., 100].

Perhaps an easier-to-understand example is the slightly simpler

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(100)
y = x
t = x
plt.scatter(x, y, c=t)
plt.show()

Note that the array you pass as c doesn't need to have any particular order or type, i.e. it doesn't need to be sorted or integers as in these examples. The plotting routine will scale the colormap such that the minimum/maximum values in c correspond to the bottom/top of the colormap.

Colormaps

You can change the colormap by adding

import matplotlib.cm as cm
plt.scatter(x, y, c=t, cmap=cm.cmap_name)

Importing matplotlib.cm is optional as you can call colormaps as cmap="cmap_name" just as well. There is a reference page of colormaps showing what each looks like. Also know that you can reverse a colormap by simply calling it as cmap_name_r. So either

plt.scatter(x, y, c=t, cmap=cm.cmap_name_r)
# or
plt.scatter(x, y, c=t, cmap="cmap_name_r")

will work. Examples are "jet_r" or cm.plasma_r. Here's an example with the new 1.5 colormap viridis:

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(100)
y = x
t = x
fig, (ax1, ax2) = plt.subplots(1, 2)
ax1.scatter(x, y, c=t, cmap='viridis')
ax2.scatter(x, y, c=t, cmap='viridis_r')
plt.show()

Colorbars

You can add a colorbar by using

plt.scatter(x, y, c=t, cmap='viridis')
plt.colorbar()
plt.show()

Note that if you are using figures and subplots explicitly (e.g. fig, ax = plt.subplots() or ax = fig.add_subplot(111)), adding a colorbar can be a bit more involved. Good examples can be found here for a single subplot colorbar and here for 2 subplots 1 colorbar.

Try using this code for v3:

gMap = new google.maps.Map(document.getElementById('map')); 
gMap.setZoom(13);      // This will trigger a zoom_changed on the map
gMap.setCenter(new google.maps.LatLng(37.4419, -122.1419));
gMap.setMapTypeId(google.maps.MapTypeId.ROADMAP);

If you have m2e installed and the project already is a maven project but the maven dependencies are still missing, the easiest way that worked for me was

• right click the project,
• Maven,
• Update Project...

An easier way that works regardless of the OS is to do

git rm -r --cached .
git add .
git commit -m "Drop files from .gitignore"

You basically remove and re-add all files, but git add will ignore the ones in .gitignore.

Using the --cached option will keep files in your filesystem, so you won't be removing files from your disk.

Note: Some pointed out in the comments that you will lose the history of all your files. I tested this with git 2.27.0 on MacOS and it is not the case. If you want to check what is happening, check your git diff HEAD~1 before you push your commit.

This is a kotlin solution. Put this helper method in some kotlin file-

fun EditText.setupClearButtonWithAction() {

    addTextChangedListener(object : TextWatcher {
        override fun afterTextChanged(editable: Editable?) {
            val clearIcon = if (editable?.isNotEmpty() == true) R.drawable.ic_clear else 0
            setCompoundDrawablesWithIntrinsicBounds(0, 0, clearIcon, 0)
        }

        override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) = Unit
        override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) = Unit
    })

    setOnTouchListener(View.OnTouchListener { _, event ->
        if (event.action == MotionEvent.ACTION_UP) {
            if (event.rawX >= (this.right - this.compoundPaddingRight)) {
                this.setText("")
                return@OnTouchListener true
            }
        }
        return@OnTouchListener false
    })
}

And then use it as following in the onCreate method and you should be good to go-

yourEditText.setupClearButtonWithAction()

BTW, you have to add R.drawable.ic_clear or the clear icon at first. This one is from google- https://material.io/tools/icons/?icon=clear&style=baseline

I think that your model #2 is fine, however you can take a look at the more complex model which stores questions and pre-made answers (offered answers) and allows them to be re-used in different surveys.

- One survey can have many questions; one question can be (re)used in many surveys.
- One (pre-made) answer can be offered for many questions. One question can have many answers offered. A question can have different answers offered in different surveys. An answer can be offered to different questions in different surveys. There is a default "Other" answer, if a person chooses other, her answer is recorded into Answer.OtherText.
- One person can participate in many surveys, one person can answer specific question in a survey only once.

@pst gave a great answer, but I'd like to mention that in Ruby the ternary operator is written on one line to be syntactically correct, unlike Perl and C where we can write it on multiple lines:

(true) ? 1 : 0

Normally Ruby will raise an error if you attempt to split it across multiple lines, but you can use the \ line-continuation symbol at the end of a line and Ruby will be happy:

(true)   \
  ? 1    \
  : 0

This is a simple example, but it can be very useful when dealing with longer lines as it keeps the code nicely laid out.

It's also possible to use the ternary without the line-continuation characters by putting the operators last on the line, but I don't like or recommend it:

(true) ?
  1 :
  0

I think that leads to really hard to read code as the conditional test and/or results get longer.

I've read comments saying not to use the ternary operator because it's confusing, but that is a bad reason to not use something. By the same logic we shouldn't use regular expressions, range operators ('..' and the seemingly unknown "flip-flop" variation). They're powerful when used correctly, so we should learn to use them correctly.

Why have you put brackets around true?

Consider the OP's example:

<% question = question.size > 20 ? question.question.slice(0, 20)+"..." : question.question %>

Wrapping the conditional test helps make it more readable because it visually separates the test:

<% question = (question.size > 20) ? question.question.slice(0, 20)+"..." : question.question %>

Of course, the whole example could be made a lot more readable by using some judicious additions of whitespace. This is untested but you'll get the idea:

<% question = (question.size > 20) ? question.question.slice(0, 20) + "..." \
                                   : question.question 
%>

Or, more written more idiomatically:

<% question = if (question.size > 20)
                question.question.slice(0, 20) + "..."
              else 
                question.question 
              end
%>

It'd be easy to argument that readability suffers badly from question.question too.

try like this

    box-sizing: border-box;

To remove packages in folder node_modules in bulk, you could also remove them from file package.json, save it, and then run npm prune in the terminal.

This will remove those packages, which exist in the file system, but are not used/declared in file package.json.

P.S.: This is particularly useful on Windows, as you may often encounter problems with being unable to delete some files due to the "exceeded path length limit".

Bash alias for updating current active version:

alias nodeupdate='nvm install $(nvm current | sed -rn "s/v([[:digit:]]+).*/\1/p") --reinstall-packages-from=$(nvm current)'

The part sed -rn "s/v([[:digit:]]+).*/\1/p" transforms output from nvm current so that only a major version of node is returned, i.e.: v13.5.0 -> 13.

I have checked the links in Gumbo's answer, and I wanted to paste some part of those things here to exist on Stack Overflow as well.

"...Some people are under the misconception that Unicode is simply a 16-bit code where each character takes 16 bits and therefore there are 65,536 possible characters. This is not, actually, correct. It is the single most common myth about Unicode, so if you thought that, don't feel bad.

In fact, Unicode has a different way of thinking about characters, and you have to understand the Unicode way of thinking of things or nothing will make sense.

Until now, we've assumed that a letter maps to some bits which you can store on disk or in memory:

A -> 0100 0001

In Unicode, a letter maps to something called a code point which is still just a theoretical concept. How that code point is represented in memory or on disk is a whole other story..."

"...Every platonic letter in every alphabet is assigned a magic number by the Unicode consortium which is written like this: U+0639. This magic number is called a code point. The U+ means "Unicode" and the numbers are hexadecimal. U+0639 is the Arabic letter Ain. The English letter A would be U+0041...."

"...OK, so say we have a string:

Hello

which, in Unicode, corresponds to these five code points:

U+0048 U+0065 U+006C U+006C U+006F.

Just a bunch of code points. Numbers, really. We haven't yet said anything about how to store this in memory or represent it in an email message..."

"...That's where encodings come in.

The earliest idea for Unicode encoding, which led to the myth about the two bytes, was, hey, let's just store those numbers in two bytes each. So Hello becomes

00 48 00 65 00 6C 00 6C 00 6F

Right? Not so fast! Couldn't it also be:

48 00 65 00 6C 00 6C 00 6F 00 ? ..."

I have been working with Swift 3.0 and wanted to contribute an answer for the updated syntax. Additionally, and possibly more importantly, I am using the PropertyListSerialization object to do the heavy lifting, which is a lot more flexible than just using the NSDictionary as it allows for an Array as the root type of the plist.

Below is a screenshot of the plist I am using. It is a little complicated, so as to show the power available, but this will work for any allowable combination of plist types.

As you can see I am using an Array of String:String dictionaries to store a list of website names and their corresponding URL.

I am using the PropertyListSerialization object, as mentioned above, to do the heavy lifting for me. Additionally, Swift 3.0 has become more "Swifty" so all of the object names have lost the "NS" prefix.

let path = Bundle.main().pathForResource("DefaultSiteList", ofType: "plist")!
let url = URL(fileURLWithPath: path)
let data = try! Data(contentsOf: url)
let plist = try! PropertyListSerialization.propertyList(from: data, options: .mutableContainers, format: nil)

After the above code runs plist will be of type Array<AnyObject>, but we know what type it really is so we can cast it to the correct type:

let dictArray = plist as! [[String:String]]
// [[String:String]] is equivalent to Array< Dictionary<String, String> >

And now we can access the various properties of our Array of String:String Dictionaries in a natural way. Hopefully to convert them into actual strongly typed structs or classes ;)

print(dictArray[0]["Name"])

If it's a File, you can get the parts by creating an instanceof File and then ask for its segments.

This is good because it'll work regardless of the direction of the slashes; it's platform independent (except for the "drive letters" in windows...)

Use setInterval()

setInterval(function(){
 alert("Hello"); 
}, 3000);

The above will execute alert("Hello"); every 3 seconds.

Some more details in relation with the response from Cody Gray. As it took me some time to digest it I though it might be usefull to others.

First, some definitions:

1. There are TypeNames, which are string representations of the type of an object, interface, etc. For example, Bar is a TypeName in Public Class Bar, or in Dim Foo as Bar. TypeNames could be seen as "labels" used in the code to tell the compiler which type definition to look for in a dictionary where all available types would be described.
2. There are System.Type objects which contain a value. This value indicates a type; just like a String would take some text or an Int would take a number, except we are storing types instead of text or numbers. Type objects contain the type definitions, as well as its corresponding TypeName.

Second, the theory:

1. Foo.GetType() returns a Type object which contains the type for the variable Foo. In other words, it tells you what Foo is an instance of.
2. GetType(Bar) returns a Type object which contains the type for the TypeName Bar.

3. In some instances, the type an object has been Cast to is different from the type an object was first instantiated from. In the following example, MyObj is an Integer cast into an Object:

   Dim MyVal As Integer = 42 Dim MyObj As Object = CType(MyVal, Object)

So, is MyObj of type Object or of type Integer? MyObj.GetType() will tell you it is an Integer.

4. But here comes the Type Of Foo Is Bar feature, which allows you to ascertain a variable Foo is compatible with a TypeName Bar. Type Of MyObj Is Integer and Type Of MyObj Is Object will both return True. For most cases, TypeOf will indicate a variable is compatible with a TypeName if the variable is of that Type or a Type that derives from it. More info here: https://docs.microsoft.com/en-us/dotnet/visual-basic/language-reference/operators/typeof-operator#remarks

The test below illustrate quite well the behaviour and usage of each of the mentionned keywords and properties.

Public Sub TestMethod1()

    Dim MyValInt As Integer = 42
    Dim MyValDble As Double = CType(MyValInt, Double)
    Dim MyObj As Object = CType(MyValDble, Object)

    Debug.Print(MyValInt.GetType.ToString) 'Returns System.Int32
    Debug.Print(MyValDble.GetType.ToString) 'Returns System.Double
    Debug.Print(MyObj.GetType.ToString) 'Returns System.Double

    Debug.Print(MyValInt.GetType.GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(MyValDble.GetType.GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(MyObj.GetType.GetType.ToString) 'Returns System.RuntimeType

    Debug.Print(GetType(Integer).GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(GetType(Double).GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(GetType(Object).GetType.ToString) 'Returns System.RuntimeType

    Debug.Print(MyValInt.GetType = GetType(Integer)) '# Returns True
    Debug.Print(MyValInt.GetType = GetType(Double)) 'Returns False
    Debug.Print(MyValInt.GetType = GetType(Object)) 'Returns False

    Debug.Print(MyValDble.GetType = GetType(Integer)) 'Returns False
    Debug.Print(MyValDble.GetType = GetType(Double)) '# Returns True
    Debug.Print(MyValDble.GetType = GetType(Object)) 'Returns False

    Debug.Print(MyObj.GetType = GetType(Integer)) 'Returns False
    Debug.Print(MyObj.GetType = GetType(Double)) '# Returns True
    Debug.Print(MyObj.GetType = GetType(Object)) 'Returns False

    Debug.Print(TypeOf MyObj Is Integer) 'Returns False
    Debug.Print(TypeOf MyObj Is Double) '# Returns True
    Debug.Print(TypeOf MyObj Is Object) '# Returns True


End Sub

EDIT

You can also use Information.TypeName(Object) to get the TypeName of a given object. For example,

Dim Foo as Bar
Dim Result as String
Result = TypeName(Foo)
Debug.Print(Result) 'Will display "Bar"

The current answer is incomplete. Installing libv4l-dev creates a /usr/include/linux/videodev2.h but doesn't solve the stated problem of not being able to find linux/videodev.h. The library does ship header files for compatibility, but fails to put them where applications will look for them.

sudo apt-get install libv4l-dev
cd /usr/include/linux
sudo ln -s ../libv4l1-videodev.h videodev.h

This provides a linux/videodev.h, and of the right version (1).

I achieved this via -

 <p style="display:none">{{user.role="store_user"}}</p>

Just to add to the other answers: In case you don't like the onload callback approach, you can "promisify" it like so:

let url = "data:image/gif;base64,R0lGODl...";
let img = new Image();
await new Promise(r => img.onload=r, img.src=url);
// now do something with img

This is a general solution to your problem. But there is one very important part that the file extension should match your encoding. And of course, that content parameter of downlowadImage function should be base64 encoded string of your image.

const clearUrl = url => url.replace(/^data:image\/\w+;base64,/, '');_x000D_

The fetch API is not implemented in Node.

You need to use an external module for that, like node-fetch.

Install it in your Node application like this

npm i node-fetch --save

then put the line below at the top of the files where you are using the fetch API:

const fetch = require("node-fetch");

For Excel 2010 it should be UTF-8. Instruction by MS :
http://msdn.microsoft.com/en-us/library/bb507946:

"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
    <sheets>
        <sheet name="MySheet1" sheetId="1" r:id="rId1" /> 
        <sheet name="MySheet2" sheetId="2" r:id="rId2" /> 
    </sheets>
</workbook>

The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" ?> 
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
    <sheetData>
        <row r="1">
            <c r="A1">
                <v>100</v>

        </row>
    </sheetData>
</worksheet>
