Try below structure for applying two color border,

<div class="white">
    <div class="grey">
    </div>
</div>

.white
{
    border: 2px solid white;   
}

.grey
{
    border: 1px solid grey;

Under Chrome v51 on a Mac, I found the rendering settings by clicking in the upper right corner, choosing More tools > Rendering settings and checking the Emulate media button in the options offered at the bottom of the window.

Thank you to all the other posters that led me to this, and credit to those that provided the answer without the images.

Another way is to use box-shadow:

#mybox {
box-shadow:
  0 0 0 1px #CCC,
  0 0 0 2px #888,
  0 0 0 3px #444,
  0 0 0 4px #000;
-moz-box-shadow:
  0 0 0 1px #CCC,
  0 0 0 2px #888,
  0 0 0 3px #444,
  0 0 0 4px #000;
-webkit-shadow:
  0 0 0 1px #CCC,
  0 0 0 2px #888,
  0 0 0 3px #444,
  0 0 0 4px #000;
}

<div id="mybox">ABC</div>

See example here.

That code looks like the route you want to take with a few changes.

You'll want to change the append method to look like this. I've changed it to accept the number 0, and to make it return this so you can chain your appends.

StringBuilder.prototype.append = function (value) {
    if (value || value === 0) {
        this.strings.push(value);
    }
    return this;
}

For those of us who have a github.com account, but only get a nasty error message when we type "git" into the command-line, here's how to do it all in your browser :)

1. Same as Tim and Farhan wrote: Fork your own copy of the project:
2. After a few seconds, you'll be redirected to your own forked copy of the project:
3. Navigate to the file(s) you need to change and click "Edit this file" in the toolbar:
4. After editing, write a few words describing the changes and then "Commit changes", just as well to the master branch (since this is only your own copy and not the "main" project).
5. Repeat steps 3 and 4 for all files you need to edit, and then go back to the root of your copy of the project. There, click the green "Compare, review..." button:
6. Finally, click "Create pull request" ..and then "Create pull request" again after you've double-checked your request's heading and description:

I like to think of the general difference as being:

• JOINS join tables
• UNION (et all) combines queries.

jQuery("input:radio[name=myradiobutton]:checked").val();

for i in range(10,0,-1):
    print i,

The range() function will include the first value and exclude the second.

Got this error because I had the Data Source Name in User DSN instead of System DSN

You can use pytz as well..

import datetime
import pytz
def utcnow():
    return datetime.datetime.now(tz=pytz.utc)
utcnow()
   datetime.datetime(2020, 8, 15, 14, 45, 19, 182703, tzinfo=<UTC>)
utcnow().isoformat()

'

2020-08-15T14:45:21.982600+00:00'

You need the ip of the other pc and do:

scp user@ip_of_remote_pc:/home/user/stuff.php /Users/djorge/Desktop

it will ask you for 'user's password on the other pc.

Run this in project folder:

$ git log --pretty=format:"%C(yellow)%h %ar %C(auto)%d %Creset %s , %Cblue%cn" --graph --all

And if you like, add this line to your ~/.gitconfig:

[alias]
    ...
    list = log --pretty=format:\"%C(yellow)%h %ar %C(auto)%d %Creset %s, %Cblue%cn\" --graph --all

The biggest reason that you use LEA over a MOV is if you need to perform arithmetic on the registers that you are using to calculate the address. Effectively, you can perform what amounts to pointer arithmetic on several of the registers in combination effectively for "free."

What's really confusing about it is that you typically write an LEA just like a MOV but you aren't actually dereferencing the memory. In other words:

MOV EAX, [ESP+4]

This will move the content of what ESP+4 points to into EAX.

LEA EAX, [EBX*8]

This will move the effective address EBX * 8 into EAX, not what is found in that location. As you can see, also, it is possible to multiply by factors of two (scaling) while a MOV is limited to adding/subtracting.

select * 
from blah 
where DatetimeField between '22/02/2009 09:00:00.000' and '23/05/2009 10:30:00.000'

Depending on the country setting for the login, the month/day may need to be swapped around.

One feature of my original code

if ( typeof(x.y) != 'undefined' ) ...

that might be useful in some situations is that it is safe to use whether x exists or not. With either of the methods in gnarf's answer, one should first test for x if there is any doubt if it exists.

So perhaps all three methods have a place in one's bag of tricks.

This is a charming answer. Work well on any currency which is selected for store.

$formattedPrice = Mage::helper('core')->currency($finalPrice, true, false);

You can use Id of the field as well

$('#checkbox1').change(function() {
   if($(this).is(":checked")) {
      //'checked' event code
      return;
   }
   //'unchecked' event code
});

I agree with Kevin he has the best answer but sometimes when you have different keys in your local storage with the same values for example you want your public users to see how many times they have added their items into their baskets you need to show them the number of times as well then you ca use this:

var set = localStorage.setItem('key', 'value');
var element = document.getElementById('tagId');

for ( var i = 0, len = localStorage.length; i < len; ++i ) {
  element.innerHTML =  localStorage.getItem(localStorage.key(i)) + localStorage.key(i).length;
}

You can just go for String replace method.-

line1 = line1.replace("\"", "");

keyPressed - when the key goes down
keyReleased - when the key comes up
keyTyped - when the unicode character represented by this key is sent by the keyboard to system input.

I personally would use keyReleased for this. It will fire only when they lift their finger up.

Note that keyTyped will only work for something that can be printed (I don't know if F5 can or not) and I believe will fire over and over again if the key is held down. This would be useful for something like... moving a character across the screen or something.

For anyone stumbling upon this question, I'll post the solution to a similar problem (same error message except for the uknown host part).

Since January 15, 2020 maven central no longer supports HTTP, in favour of HTTPS. Consequently, spring repositories switched to HTTPS as well

The solution is therefore to change the urls from http://repo.spring.io/milestone to https://repo.spring.io/milestone.

You could also a for loop to do so:

#!/bin/bash
for i in *.sql
do
    echo "Importing: $i"
    mysql your_db_name < $i
    wait
done

Happened to me as well: At the first time, it says- Failure [INSTALL_FAILED_CONFLICTING_PROVIDER] At the second time, it says- DELETE_FAILED_INTERNAL_ERROR

This because of the new 'com.google.android.gms' version 8.3.0

Changing it back to 8.1.0 solved the problem in my case

For a default export we do not use { } when we import.

For example,

File player.js

export default vx;

File index.js

import vx from './player';

File index.js

If we want to import everything that we export then we use *:

I struggled with this from behind a proxy so I thought I should post what I did. Below one is worked for me.

using jquery i am able to come up with this. it doesnt scroll smooth, but it does the trick. you can scroll down, and the fixed div pops up on top.

THE CSS

<style type="text/css">
    .btn_cardDetailsPg {height:5px !important;margin-top:-20px;}
    html, body {overflow-x:hidden;overflow-y:auto;}
    #lockDiv {

  color: #000;
  float:left;
  -moz-box-shadow: 0px 4px 2px 2px #ccc;-webkit-box-shadow: 0px 4px 2px 2px #ccc;box-shadow:0px 4px 2px 2px #ccc;
  }
#lockDiv.stick {
  position: fixed;
  top: 0;
  z-index: 10000;
  margin-left:0px;
  }
</style>

THE HTML

<div id="lockSticky"></div>
<div id="lockDiv">fooo</div>

THE jQUERY

<script type="text/javascript">
    function sticky_relocate() {
        var window_top = $(window).scrollTop();
        var div_top = $('#lockSticky').offset().top;
        if (window_top > div_top)
            $('#lockDiv').addClass('stick')
        else
            $('#lockDiv').removeClass('stick');
    }
    $(function() {
        $(window).scroll(sticky_relocate);
        sticky_relocate();
    });

Finally we want to determine if the ipod touch in landscape or portrait mode to display accordingly

<script type="text/javascript">

        window.onscroll = function() {

        if (window.innerWidth > window.innerHeight) {
            //alert("landscape [ ]");
            document.getElementById('lockDiv').style.top =
            (window.pageYOffset + window.innerHeight - 268) + 'px';
        }

        if (window.innerHeight > window.innerWidth) {
            //alert("portrait ||");
            document.getElementById('lockDiv').style.top =
            (window.pageYOffset + window.innerHeight - 418) + 'px';
        }

For users coming back to this post long after the initial answer was accepted, it may pay off to note that now you can use

data-fancybox-href="#" 

on any element (since data is an HTML-5 accepted attribute) to have the fancybox work on say an input form if for some reason you can't use the options to initiate for some reason (like say you have multiple elements on the page that use fancybox and they all share a similar class you call fancybox on).

use #undef UNICODE at the top of your main file.

Slight modification of above answer to copy a folder recursively and to accommodate custom destination.

public void copyFileOrDir(String path, String destinationDir) {
    AssetManager assetManager = this.getAssets();
    String assets[] = null;
    try {
        assets = assetManager.list(path);
        if (assets.length == 0) {
            copyFile(path,destinationDir);
        } else {
            String fullPath = destinationDir + "/" + path;
            File dir = new File(fullPath);
            if (!dir.exists())
                dir.mkdir();
            for (int i = 0; i < assets.length; ++i) {
                copyFileOrDir(path + "/" + assets[i], destinationDir + path + "/" + assets[i]);
            }
        }
    } catch (IOException ex) {
        Log.e("tag", "I/O Exception", ex);
    }
}

private void copyFile(String filename, String destinationDir) {
    AssetManager assetManager = this.getAssets();
    String newFileName = destinationDir + "/" + filename;

    InputStream in = null;
    OutputStream out = null;
    try {
        in = assetManager.open(filename);
        out = new FileOutputStream(newFileName);

        byte[] buffer = new byte[1024];
        int read;
        while ((read = in.read(buffer)) != -1) {
            out.write(buffer, 0, read);
        }
        in.close();
        in = null;
        out.flush();
        out.close();
        out = null;
    } catch (Exception e) {
        Log.e("tag", e.getMessage());
    }
    new File(newFileName).setExecutable(true, false);

ASP.NET controls should rather be placed in aspx markup file. That is the preferred way of working with them. So add FileUpload control to your page. Make sure it has all required attributes including ID and runat:

<asp:FileUpload ID="FileUpload1" runat="server" />

Instance of FileUpload1 will be automatically created in auto-generated/updated *.designer.cs file which is a partial class for your page. You usually do not have to care about what's in it, just assume that any control on an aspx page is automatically instantiated.

Add a button that will do the post back:

<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />

Then go to your *.aspx.cs file where you have your code and add button click handler. In C# it looks like this:

protected void Button1_Click(object sender, EventArgs e)
{
  if (this.FileUpload1.HasFile)
  {
    this.FileUpload1.SaveAs("c:\\" + this.FileUpload1.FileName);
  }
}

And that's it. All should work as expected.

There might be just a typo anywhere inside a file imported by the config. For example, I made a typo deep inside my config file:

loccation /sense/movies/ {
                  mp4;
        }

(loccation instead of location), and this causes the error:

nginx: [emerg] "server" directive is not allowed here in /etc/nginx/sites-enabled/xxx.xx:1

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

In a more modern way, you can now use the Fetch API:

fetch("test.json")
  .then(response => response.json())
  .then(json => console.log(json));

All modern browsers support Fetch API. (Internet Explorer doesn't, but Edge does!)

I too was wondering why you can't just start microsoftedge.exe, like you do "old-style" applications in windows 10. Searching the web, I found the answer -- it has to do with how Microsoft implemented "Universal Apps".

Below is a brief summary taken from that answer, but I recommend reading the entire entry, because it gives a great explanation of how these "Universal Apps" are being dealt with. Microsoft Edge is not the only app like this we'll be dealing with.

Here's the link: http://www.itworld.com/article/2943955/windows/how-to-script-microsofts-edge-browser.html

Here's the summary from that page:

"Microsoft Edge is a "Modern" Universal app. This means it can't be opened from the command line in the traditional Windows manner:  Executable name followed by command switches/parameter values. But where there's a will, there's a way. In this case, the "way" is known as protocol activation."

Kudos to the author of the article, Stephen Glasskeys.

Simply add these code before setting Adapter it's working for me:

    listView.destroyDrawingCache();
    listView.setVisibility(ListView.INVISIBLE);

   adapter.notifyDataSetChanged()

Another possible cause of this error:

Yes since there are 2 distinct Global Assembly Cache (GAC), you will have to manage each of them individually.

In .NET Framework 4.0, the GAC went through a few changes. The GAC was split into two, one for each CLR.

The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. There was no need in the previous two framework releases to split GAC. The problem of breaking older applications in Net Framework 4.0.

To avoid issues between CLR 2.0 and CLR 4.0 , the GAC is now split into private GAC’s for each runtime.The main change is that CLR v2.0 applications now cannot see CLR v4.0 assemblies in the GAC.

Source

Why?

It seems to be because there was a CLR change in .NET 4.0 but not in 2.0 to 3.5. The same thing happened with 1.1 to 2.0 CLR. It seems that the GAC has the ability to store different versions of assemblies as long as they are from the same CLR. They do not want to break old applications.

See the following information in MSDN about the GAC changes in 4.0.

For example, if both .NET 1.1 and .NET 2.0 shared the same GAC, then a .NET 1.1 application, loading an assembly from this shared GAC, could get .NET 2.0 assemblies, thereby breaking the .NET 1.1 application

The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. As a result of this, there was no need in the previous two framework releases to split the GAC. The problem of breaking older (in this case, .NET 2.0) applications resurfaces in Net Framework 4.0 at which point CLR 4.0 released. Hence, to avoid interference issues between CLR 2.0 and CLR 4.0, the GAC is now split into private GACs for each runtime.

As the CLR is updated in future versions you can expect the same thing. If only the language changes then you can use the same GAC.

If you know the key which you unset then put directly by comma separated

unset($attr['placeholder'], $attr['autocomplete']);

Try this:

a = np.matrix([[1,2], [3,4]])
b = np.matrix([[5,6], [7,8]])

#This would result a 'numpy.ndarray'
result = np.array(a) * np.array(b)

Here, np.array(a) returns a 2D array of type ndarray and multiplication of two ndarray would result element wise multiplication. So the result would be:

result = [[5, 12], [21, 32]]

If you wanna get a matrix, the do it with this:

result = np.mat(result)

IMHO, it's a matter of personal style and opinion.

In olden days, I didn't put that newline. A character saved means more speed through that 14.4K modem.

Later, I put that newline so that it's easier to select the final line using shift+downarrow.

If you use Start-Process <path to exe> -NoNewWindow -Wait

You can also use the -PassThru option to echo output.

A list comprehension is your best bet for the most Pythonic (and fastest) way to do this:

[int(i.days) for i in (df.B - df.A)]

1. i will return the timedelta(e.g. '-58 days')
2. i.days will return this value as a long integer value(e.g. -58L)
3. int(i.days) will give you the -58 you seek.

If your columns aren't in datetime format. The shorter syntax would be: df.A = pd.to_datetime(df.A)

Many have answered this question correctly, this is just another solution (although my solution is very similar to Max Montana) but I have few differences for implementation:

let's review the general idea here before we get to the code:

• Divide the list into two roughly equal halves.
• Sort the left half.
• Sort the right half.
• Merge the two sorted halves into one sorted list.

here is the code (tested with python 3.7):

def merge(left,right):
    result=[] 
    i,j=0,0
    while i<len(left) and j<len(right):
        if left[i] < right[j]:
            result.append(left[i])
            i+=1
        else:
            result.append(right[j])
            j+=1
    result.extend(left[i:]) # since we want to add each element and not the object list
    result.extend(right[j:])
    return result

def merge_sort(data):
    if len(data)==1:
        return data
    middle=len(data)//2
    left_data=merge_sort(data[:middle])
    right_data=merge_sort(data[middle:])
    return merge(left_data,right_data)


data=[100,5,200,3,100,4,8,9] 
print(merge_sort(data))

Math.sqrt returns a double so you'll have to cast it to int as well

distance = (int)Math.sqrt((x1-x2)*(x1-x2) + (y1-y2)*(y1-y2));

What would help, except for excluding, is modular dependencies.

With one flat classloading (standalone app), or semi-hierarchical (JBoss AS/EAP 5.x) this was a problem.

But with modular frameworks like OSGi and JBoss Modules, this is not so much pain anymore. The libraries may use whichever library they want, independently.

Of course, it's still most recommendable to stick with just a single implementation and version, but if there's no other way (using extra features from more libs), then modularizing might save you.

A good example of JBoss Modules in action is, naturally, JBoss AS 7 / EAP 6 / WildFly 8, for which it was primarily developed.

Example module definition:

</module>

In comparison with OSGi, JBoss Modules is simpler and faster. While missing certain features, it's sufficient for most projects which are (mostly) under control of one vendor, and allow stunning fast boot (due to paralelized dependencies resolving).

Note that there's a modularization effort underway for Java 8, but AFAIK that's primarily to modularize the JRE itself, not sure whether it will be applicable to apps.

Installing a 64-bit version of Java will solve the issue. Go to page Java Downloads for All Operating Systems

This is a problem due to the incompatibility of the Java version and the Eclipse version both should be 64 bit if you are using a 64-bit system.

The Easiest way is this way :

from csv import reader

# open file in read mode
with open('file.csv', 'r') as read_obj:
    # pass the file object to reader() to get the reader object
    csv_reader = reader(read_obj)
    # Iterate over each row in the csv using reader object
    for row in csv_reader:
        # row variable is a list that represents a row in csv
        print(row)

output:
['Year:', 'Dec:', 'Jan:']
['1', '50', '60']
['2', '25', '50']
['3', '30', '30']
['4', '40', '20']
['5', '10', '10']

Properties have values only in objects, not classes.

If you need to store something for all objects of a class, you have to use a global variable. You can hide it by declaring it static in the implementation file.

You may also consider using specific relations between your objects: you attribute a role of master to a specific object of your class and link others objects to this master. The master will hold the dictionary as a simple property. I think of a tree like the one used for the view hierarchy in Cocoa applications.

Another option is to create an object of a dedicated class that is composed of both your 'class' dictionary and a set of all the objects related to this dictionary. This is something like NSAutoreleasePool in Cocoa.

for package in `sudo npm -g ls --depth=0 --parseable`; do
    printf "${package##*/}\n";
done

Since the application path of a JAR and an application running from inside an IDE differs, I wrote the following code to consistently return the correct current directory:

import java.io.File;
import java.net.URISyntaxException;

public class ProgramDirectoryUtilities
{
    private static String getJarName()
    {
        return new File(ProgramDirectoryUtilities.class.getProtectionDomain()
                .getCodeSource()
                .getLocation()
                .getPath())
                .getName();
    }

    private static boolean runningFromJAR()
    {
        String jarName = getJarName();
        return jarName.contains(".jar");
    }

    public static String getProgramDirectory()
    {
        if (runningFromJAR())
        {
            return getCurrentJARDirectory();
        } else
        {
            return getCurrentProjectDirectory();
        }
    }

    private static String getCurrentProjectDirectory()
    {
        return new File("").getAbsolutePath();
    }

    private static String getCurrentJARDirectory()
    {
        try
        {
            return new File(ProgramDirectoryUtilities.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath()).getParent();
        } catch (URISyntaxException exception)
        {
            exception.printStackTrace();
        }

        return null;
    }
}

Simply call getProgramDirectory() and you should be good either way.

To convert it to a single dictionary with some decided keys value, you can use the code below.

data = ListOfDict.copy()
PrecedingText = "Obs_"
ListOfDictAsDict = {}
for i in range(len(data)):
    ListOfDictAsDict[PrecedingText + str(i)] = data[i]

When You are sending a single quote in a query

empid = " T'via"
empid =escape(empid)

When You get the value including a single quote

var xxx  = request.QueryString("empid")
xxx= unscape(xxx)

If you want to search/ insert the value which includes a single quote in a query xxx=Replace(empid,"'","''")

One more method is to Define the Layout inside the View:

   @{
    Layout = "~/Views/Shared/_MyAdminLayout.cshtml";
    }

More Ways to do, can be found here, hope this helps someone.

1) in a query window in SQL Server Management Studio, run the command:

SET SHOWPLAN_ALL ON

2) run your slow query

3) your query will not run, but the execution plan will be returned. store this output

4) run your fast version of the query

5) your query will not run, but the execution plan will be returned. store this output

6) compare the slow query version output to the fast query version output.

7) if you still don't know why one is slower, post both outputs in your question (edit it) and someone here can help from there.

I'm getting SecurityError: The operation is insecure.

The file system of the container is in the data folder of docker, normally in /var/lib/docker. In order to start and inspect a running containers file system do the following:

hash=$(docker run busybox)
cd /var/lib/docker/aufs/mnt/$hash

And now the current working directory is the root of the container.

As of Jackson 1.6, you can use:

JsonNode node = mapper.valueToTree(map);

or

JsonNode node = mapper.convertValue(object, JsonNode.class);

Source: is there a way to serialize pojo's directly to treemodel?

In case of await Promise.all([task1(), task2()]); "task1()" and "task2()" will run parallel and will wait until both promises are completed (either resolved or rejected). Whereas in case of

const result1 = await t1;
const result2 = await t2;

t2 will only run after t1 has finished execution (has been resolved or rejected). Both t1 and t2 will not run parallel.

Update: Feb 2017

Here are the COMPLETE STEPS for remote access of MySQL (deployed on Amazon EC2):-

1. Add MySQL to inbound rules.

Go to security group of your ec2 instance -> edit inbound rules -> add new rule -> choose MySQL/Aurora and source to Anywhere.

2. Add bind-address = 0.0.0.0 to my.cnf

In instance console:

sudo vi /etc/mysql/my.cnf

this will open vi editor.
in my.cnf file, after [mysqld] add new line and write this:

bind-address = 0.0.0.0

Save file by entering :wq(enter)

now restart MySQL:

sudo /etc/init.d/mysqld restart

3. Create a remote user and grant privileges.

login to MySQL:

mysql -u root -p mysql (enter password after this)

Now write following commands:

CREATE USER 'jerry'@'localhost' IDENTIFIED BY 'jerrypassword';

CREATE USER 'jerry'@'%' IDENTIFIED BY 'jerrypassword';

GRANT ALL PRIVILEGES ON *.* to jerry@localhost IDENTIFIED BY 'jerrypassword' WITH GRANT OPTION;

GRANT ALL PRIVILEGES ON *.* to jerry@'%' IDENTIFIED BY 'jerrypassword' WITH GRANT OPTION;

FLUSH PRIVILEGES;

EXIT;

After this, MySQL dB can be remotely accessed by entering public dns/ip of your instance as MySQL Host Address, username as jerry and password as jerrypassword. (Port is set to default at 3306)

This sounds weird and I don't know why, but in my case that was happening because my ConnectionString was using "." in "data source" attribute. Once I changed it to "localhost" it workded like a charm. No other change was needed.

Just to spell out what has already been said in brief. I wanted to create an executable JAR file that included my dependencies along with my code. This worked for me:

(1) In the pom, under <build><plugins>, I included:

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.2-beta-5</version>
    <configuration>
        <archive>
            <manifest>
                <mainClass>dk.certifikat.oces2.some.package.MyMainClass</mainClass>
            </manifest>
        </archive>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
</plugin>

(2) Running mvn compile assembly:assembly produced the desired my-project-0.1-SNAPSHOT-jar-with-dependencies.jar in the project's target directory.

(3) I ran the JAR with java -jar my-project-0.1-SNAPSHOT-jar-with-dependencies.jar

SelThroughJava's answer was very helpful I had to modify a bit to my code to be worked . I used https://mvnrepository.com/artifact/org.apache.poi/poi and https://mvnrepository.com/artifact/org.testng/testng as dependencies . Full code is given below with exact imports.

 import java.io.FileInputStream;
    import java.io.FileNotFoundException;
    import java.io.IOException;

    import org.apache.poi.hssf.usermodel.HSSFCell;
    import org.apache.poi.hssf.util.CellReference;
    import org.apache.poi.sl.usermodel.Sheet;
    import org.apache.poi.ss.usermodel.Cell;
    import org.apache.poi.ss.usermodel.CellType;
    import org.apache.poi.ss.usermodel.CellValue;
    import org.apache.poi.ss.usermodel.FormulaEvaluator;
    import org.apache.poi.ss.usermodel.Row;
    import org.apache.poi.ss.usermodel.Workbook;
    import org.apache.poi.ss.usermodel.WorkbookFactory;
    import org.apache.poi.xssf.usermodel.XSSFWorkbook;


    public class ReadExcelFormulaValue {

        private static final CellType NUMERIC = null;
        public static void main(String[] args) {
            try {
                readFormula();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        public static void readFormula() throws IOException {
            FileInputStream fis = new FileInputStream("C:eclipse-workspace\\sam-webdbriver-diaries\\resources\\tUser_WS.xls");
            org.apache.poi.ss.usermodel.Workbook workbook = WorkbookFactory.create(fis);
            org.apache.poi.ss.usermodel.Sheet sheet = workbook.getSheetAt(0);

            FormulaEvaluator evaluator = workbook.getCreationHelper().createFormulaEvaluator();

            CellReference cellReference = new CellReference("G2"); // pass the cell which contains the formula
            Row row = sheet.getRow(cellReference.getRow());
            Cell cell = row.getCell(cellReference.getCol());

            CellValue cellValue = evaluator.evaluate(cell);
            System.out.println("Cell type month  is "+cellValue.getCellTypeEnum());
            System.out.println("getNumberValue month is  "+cellValue.getNumberValue());     
          //  System.out.println("getStringValue "+cellValue.getStringValue());


            cellReference = new CellReference("H2"); // pass the cell which contains the formula
             row = sheet.getRow(cellReference.getRow());
             cell = row.getCell(cellReference.getCol());

            cellValue = evaluator.evaluate(cell);
            System.out.println("getNumberValue DAY is  "+cellValue.getNumberValue());    


        }

    }

There is an updated version of Tom Gibara's tutorial. You can change the Webcam Broadcaster to work with JMyron instead of the old JMF.

The new emulator (sdk r15) manage webcams ; but it has some problems with integrated webcams (at least with mine's ^^)

you can set pointer on last position of textbox as per following.

temp=$("#txtName").val();
$("#txtName").val('');
$("#txtName").val(temp);
$("#txtName").focus();

My problem was that I was trying to create the relation table before other tables!

operator bool() const 
{
    return col != 0;
}

Defines how the class is convertable to a boolean value, the const after the () is used to indicate this method does not mutate (change the members of this class).

You would usually use such operators as follows:

airplaysdk sdkInstance;
if (sdkInstance) {
    std::cout << "Instance is active" << std::endl;
} else {
    std::cout << "Instance is in-active error!" << std::endl;
}

We can pretend they are filenames and remove extensions:

tools::file_path_sans_ext(a)
# [1] "NM_020506"    "NM_020519"    "NM_001030297" "NM_010281"    "NM_011419"    "NM_053155"

To know the actual date format, insert a record by using sysdate. That way you can find the actual date format. for example

insert into emp values(7936, 'Mac', 'clerk', 7782, sysdate, 1300, 300, 10);

now, select the inserted record.

select ename, hiredate from emp where ename='Mac';

the result is

ENAME   HIREDATE
Mac     06-JAN-13

voila, now your actual date format is found.

Another way to applyhorizontalalignment and rotation to each tick label is doing a for loop over the tick labels you want to change:

import numpy as np
import matplotlib.pyplot as plt
import datetime as dt

now = dt.datetime.now()
hours = [now + dt.timedelta(minutes=x) for x in range(0,24*60,10)]
days = [now + dt.timedelta(days=x) for x in np.arange(0,30,1/4.)]
hours_value = np.random.random(len(hours))
days_value = np.random.random(len(days))

fig, axs = plt.subplots(2)
fig.subplots_adjust(hspace=0.75)
axs[0].plot(hours,hours_value)
axs[1].plot(days,days_value)

for label in axs[0].get_xmajorticklabels() + axs[1].get_xmajorticklabels():
    label.set_rotation(30)
    label.set_horizontalalignment("right")

And here is an example if you want to control the location of major and minor ticks:

import numpy as np
import matplotlib.pyplot as plt
import datetime as dt

fig, axs = plt.subplots(2)
fig.subplots_adjust(hspace=0.75)
now = dt.datetime.now()
hours = [now + dt.timedelta(minutes=x) for x in range(0,24*60,10)]
days = [now + dt.timedelta(days=x) for x in np.arange(0,30,1/4.)]

axs[0].plot(hours,np.random.random(len(hours)))
x_major_lct = mpl.dates.AutoDateLocator(minticks=2,maxticks=10, interval_multiples=True)
x_minor_lct = matplotlib.dates.HourLocator(byhour = range(0,25,1))
x_fmt = matplotlib.dates.AutoDateFormatter(x_major_lct)
axs[0].xaxis.set_major_locator(x_major_lct)
axs[0].xaxis.set_minor_locator(x_minor_lct)
axs[0].xaxis.set_major_formatter(x_fmt)
axs[0].set_xlabel("minor ticks set to every hour, major ticks start with 00:00")

axs[1].plot(days,np.random.random(len(days)))
x_major_lct = mpl.dates.AutoDateLocator(minticks=2,maxticks=10, interval_multiples=True)
x_minor_lct = matplotlib.dates.DayLocator(bymonthday = range(0,32,1))
x_fmt = matplotlib.dates.AutoDateFormatter(x_major_lct)
axs[1].xaxis.set_major_locator(x_major_lct)
axs[1].xaxis.set_minor_locator(x_minor_lct)
axs[1].xaxis.set_major_formatter(x_fmt)
axs[1].set_xlabel("minor ticks set to every day, major ticks show first day of month")
for label in axs[0].get_xmajorticklabels() + axs[1].get_xmajorticklabels():
    label.set_rotation(30)
    label.set_horizontalalignment("right")

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html

Otherwise you are passing ncols to np.zeros as the dtype.

It should be like import package_name.Class_Name --> If you want to import a specific class (or)

import package_name.* --> To import all classes in a package

Simply create a property in your view model of type MvcHtmlString. You won't need to Html.Raw it then either.

You need to use the option -f:

$ grep -f A B

The option -F does a fixed string search where as -f is for specifying a file of patterns. You may want both if the file only contains fixed strings and not regexps.

$ grep -Ff A B

You may also want the -w option for matching whole words only:

$ grep -wFf A B

Read man grep for a description of all the possible arguments and what they do.

To set the placeholder color once for all the UITextField in your app you can do:

UILabel.appearanceWhenContainedInInstancesOfClasses([UITextField.self]).textColor = UIColor.redColor()

This will set the desired color for all TextField placeholders in the entire app. But it is only available since iOS 9.

There is no appearenceWhenContainedIn....() method before iOS 9 in swift but you can use one of the solutions provided here appearanceWhenContainedIn in Swift

The problem is with percentage sizing. You are not defining the size of the parent div (the new one), so the browser can not report the size to the Google Maps API. Giving the wrapper div a specific size, or a percentage size if the size of its parent can be determined, will work.

See this explanation from Mike Williams' Google Maps API v2 tutorial:

If you try to use style="width:100%;height:100%" on your map div, you get a map div that has zero height. That's because the div tries to be a percentage of the size of the <body>, but by default the <body> has an indeterminate height.

There are ways to determine the height of the screen and use that number of pixels as the height of the map div, but a simple alternative is to change the <body> so that its height is 100% of the page. We can do this by applying style="height:100%" to both the <body> and the <html>. (We have to do it to both, otherwise the <body> tries to be 100% of the height of the document, and the default for that is an indeterminate height.)

Add the 100% size to html and body in your css

    html, body, #map-canvas {
        margin: 0;
        padding: 0;
        height: 100%;
        width: 100%;
    }

Add it inline to any divs that don't have an id:

<body>
  <div style="height:100%; width: 100%;"> 
    <div id="map-canvas"></div>
  </div>
</body>

Copy code using clone and appendTo function :

Here is also working example jsfiddle

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
</head>
<body>
<div id="copy"><a href="http://brightwaay.com">Here</a> </div>
<br/>
<div id="copied"></div>
<script type="text/javascript">
    $(function(){
        $('#copy').clone().appendTo('#copied');
    });
</script>
</body>
</html>

Just as an alternative approach to you can do:

WITH inner_table AS
(SELECT A.identifier
    , A.name
    , TO_NUMBER(DECODE( A.month_no
      , 1, 200803 
      , 2, 200804 
      , 3, 200805 
      , 4, 200806 
      , 5, 200807 
      , 6, 200808 
      , 7, 200809 
      , 8, 200810 
      , 9, 200811 
      , 10, 200812 
      , 11, 200701 
      , 12, 200702
      , NULL)) as MONTH_NO
    , TO_NUMBER(TO_CHAR(B.last_update_date, 'YYYYMM')) as UPD_DATE
  FROM table_a A
    , table_b B
  WHERE A.identifier = B.identifier)

    SELECT * FROM inner_table 
    WHERE MONTH_NO > UPD_DATE

Also you can create a permanent view for your queue and select from view.

CREATE OR REPLACE VIEW_1 AS (SELECT ...);
SELECT * FROM VIEW_1;

SRC(Source) -- I want to load up this resource for myself.

For example:

Absolute URL with script element: <script src="http://googleapi.com/jquery/script.js"></script>   

Relative URL with img element : <img src="mypic.jpg">

HREF(Hypertext REFerence) -- I want to refer to this resource for someone else.

For example:

Absolute URL with anchor element: <a href="http://www.google.com/">Click here</a>

Relative URL with link element: <link href="mystylesheet.css" type="text/css">

I'm using cocoapods version 1.0.1 and using pod update name-of-pod works perfectly. No other pods are updated, just the specific one you enter.

The variable selectedHero is null in the template so you cannot bind selectedHero.name as is. You need to use the elvis operator ?. for this case:

<input [ngModel]="selectedHero?.name" (ngModelChange)="selectedHero.name = $event" />

The separation of the [(ngModel)] into [ngModel] and (ngModelChange) is also needed because you can't assign to an expression that uses the elvis operator.

I also think you mean to use:

<h2>{{selectedHero?.name}} details!</h2>

instead of:

<h2>{{hero.name}} details!</h2>

I was looking for a good option for IE10 and below CSS styling (but it would work for IE8 only as well) and I came up with this idea:

<!--[if lt IE 10]><div class="column IE10-fix"><![endif]-->
<!--[if !lt IE 10]><!--><div class="column"><!--<![endif]-->

I declare my div or whatever you want with an extra class, this allows me to have extra CSS in the same stylesheet in a very readable manner.

It's W3C valid and not a weird CSS hack.

Use the time package to work with time information in Go.

Time instants can be compared using the Before, After, and Equal methods. The Sub method subtracts two instants, producing a Duration. The Add method adds a Time and a Duration, producing a Time.

Play example:

package main

import (
    "fmt"
    "time"
)

func inTimeSpan(start, end, check time.Time) bool {
    return check.After(start) && check.Before(end)
}

func main() {
    start, _ := time.Parse(time.RFC822, "01 Jan 15 10:00 UTC")
    end, _ := time.Parse(time.RFC822, "01 Jan 16 10:00 UTC")

    in, _ := time.Parse(time.RFC822, "01 Jan 15 20:00 UTC")
    out, _ := time.Parse(time.RFC822, "01 Jan 17 10:00 UTC")

    if inTimeSpan(start, end, in) {
        fmt.Println(in, "is between", start, "and", end, ".")
    }

    if !inTimeSpan(start, end, out) {
        fmt.Println(out, "is not between", start, "and", end, ".")
    }
}

My impression is that your database is pretty enourmous or very badly designed if Linq2Sql does not fit your needs. I have around 10 websites both larger and smaller all using Linq2Sql. I have looked and Entity framework many times but I cannot find a good reason for using it over Linq2Sql. That said I try to use my databases as model so I already have a 1 to 1 mapping between model and database.

At my current job we have a database with 200+ tables. An old database with lots of bad solutions so there I could see the benefit of Entity Framework over Linq2Sql but still I would prefer to redesign the database since the database is the engine of the application and if the database is badly designed and slow then my application will also be slow. Using Entity framework on such a database seems like a quickfix to disguise the bad model but it could never disguise the bad performance you get from such a database.

I think you should have a look at the Pathogen plugin. After you have this installed, you can keep all of your plugins in separate folders in ~/.vim/bundle/, and Pathogen will take care of loading them.

Or, alternatively, perhaps you would prefer Vundle, which provides similar functionality (with the added bonus of automatic updates from plugins in github).

I tried working with the string form rather than the number and this seemed to work. I have only tested this on Chrome but it should be universal:

function removeExponent(s) {
    var ie = s.indexOf('e');
    if (ie != -1) {
        if (s.charAt(ie + 1) == '-') {
            // negative exponent, prepend with .0s
            var n = s.substr(ie + 2).match(/[0-9]+/);
            s = s.substr(2, ie - 2); // remove the leading '0.' and exponent chars
            for (var i = 0; i < n; i++) {
                s = '0' + s;
            }
            s = '.' + s;
        } else {
            // positive exponent, postpend with 0s
            var n = s.substr(ie + 1).match(/[0-9]+/);
            s = s.substr(0, ie); // strip off exponent chars            
            for (var i = 0; i < n; i++) {
                s += '0';
            }       
        }
    }
    return s;
}

I had this challenge when I was working on a Rails 6 application using Bootstrap 4.

My challenge was that I didn't want this styling to override the default link styling in the application.

So I created a CSS file called custom.css or custom.scss.

And then defined a new CSS rule with the following properties:

.remove_link_colour {
  a, a:hover, a:focus, a:active {
      color: inherit;
      text-decoration: none;
  }
}

Then I called this rule wherever I needed to override the default link styling.

<div class="product-card__buttons">
  <button class="btn btn-success remove_link_colour" type="button"><%= link_to 'Edit', edit_product_path(product) %></button>
  <button class="btn btn-danger remove_link_colour" type="button"><%= link_to 'Destroy', product, method: :delete, data: { confirm: 'Are you sure?' } %></button>
</div>

This solves the issue of overriding the default link styling and removes the default colour, hover, focus, and active styling in the buttons only in places where I call the CSS rule.

That's all.

I hope this helps

In Swift use this,

If you wants to have pull to refresh in WebView,

So try this code:

override func viewDidLoad() {
    super.viewDidLoad()
    addPullToRefreshToWebView()
}

func addPullToRefreshToWebView(){
    var refreshController:UIRefreshControl = UIRefreshControl()

    refreshController.bounds = CGRectMake(0, 50, refreshController.bounds.size.width, refreshController.bounds.size.height) // Change position of refresh view
    refreshController.addTarget(self, action: Selector("refreshWebView:"), forControlEvents: UIControlEvents.ValueChanged)
    refreshController.attributedTitle = NSAttributedString(string: "Pull down to refresh...")
    YourWebView.scrollView.addSubview(refreshController)

}

func refreshWebView(refresh:UIRefreshControl){
    YourWebView.reload()
    refresh.endRefreshing()
}

Had the same issue with Ionic routing.

Simple solution is to use the name of the state - basically state.go(state name)

.state('tab.search', {
    url: '/search',
    views: {
      'tab-search': {
        templateUrl: 'templates/search.html',
        controller: 'SearchCtrl'
      }
    }
  })

And in controller you can use $state.go('tab.search');

Or maybe even easier

grep -R put **/*bills*

The ** glob syntax means "any depth of directories". It will work in Zsh, and I think recent versions of Bash too.

You should be able to transfer the Application to another Username. You would need all your old user information to transfer it. The application would remove it's self from old account to new account. Also you could put a limit on how many times you where allowed to transfer it. If you transfer it to the application could expire after a year and force to buy update.

I tried the steps that @KannarKK suggested on ES 2.0.2, however, I could not bring the cluster up and running. Evidently, I figured out something, as I had set tcp port number on Master, on the Slave configuration discovery.zen.ping.unicast.hosts needs Master's port number along with IP address ( tcp port number ) for discovery. So when I try following configuration it works for me.

Node 1

cluster.name: mycluster
node.name: "node1"
node.master: true
node.data: true
http.port : 9200
tcp.port : 9300
discovery.zen.ping.multicast.enabled: false
# I think unicast.host on master is redundant.
discovery.zen.ping.unicast.hosts: ["node1.example.com"]

Node 2

cluster.name: mycluster
node.name: "node2"
node.master: false
node.data: true
http.port : 9201
tcp.port : 9301
discovery.zen.ping.multicast.enabled: false
# The port number of Node 1
discovery.zen.ping.unicast.hosts: ["node1.example.com:9300"]

Use the below code. Align the button to buttom. It's working.

From the Sonatype doc:

The answer to this question depends on your own perspective. The great majority of Maven users are going to call Maven a “build tool”: a tool used to build deployable artifacts from source code. Build engineers and project managers might refer to Maven as something more comprehensive: a project management tool. What is the difference? A build tool such as Ant is focused solely on preprocessing, compilation, packaging, testing, and distribution. A project management tool such as Maven provides a superset of features found in a build tool. In addition to providing build capabilities, Maven can also run reports, generate a web site, and facilitate communication among members of a working team.

I'd strongly recommend looking at the Sonatype doc and spending some time looking at the available plugins to understand the power of Maven.

Very briefly, it operates at a higher conceptual level than (say) Ant. With Ant, you'd specify the set of files and resources that you want to build, then specify how you want them jarred together, and specify the order that should occur in (clean/compile/jar). With Maven this is all implicit. Maven expects to find your files in particular places, and will work automatically with that. Consequently setting up a project with Maven can be a lot simpler, but you have to play by Maven's rules!

Yes, window.onfocus and window.onblur should work for your scenario:

I returned to a system after a while, and even though it had Node 12.x, there was no npx or even npm available. I had installed Node via nvm, so I removed it, reinstalled it and then installed the latest Node LTS. This got me both npm and npx.

<div style="float: left;">
<?php 
  echo("<a href=\"pagea.php?id=$id\">Page A</a>") 
?>
</div>
<div id="contentInfo_new" style="float: left;">
  <script type="text/javascript" src="getData.php?id=<?php echo($id); ?>"></script>
</div>

I know this is a pretty old topic, but I also had a same problem.

My solution:

how we fill the combobox:

foreach (KeyValuePair<int, string> item in listRegion)
{
    combo.Items.Add(item.Value);
    combo.ValueMember = item.Value.ToString();
    combo.DisplayMember = item.Key.ToString();
    combo.SelectedIndex = 0;
}

and that's how we get inside:

 MessageBox.Show(combo_region.DisplayMember.ToString());

I hope it help someone

It's entirely dependent upon the actual function and the meaning of the multiple values, and their sizes:

• If they're related as in your fraction example, then I'd go with a struct or class instance.
• If they're not really related and can't be grouped into a class/struct then perhaps you should refactor your method into two.
• Depending upon the in-memory size of the values you're returning, you may want to return a pointer to a class instance or struct, or use reference parameters.

Adding to @HYRY's answer in1d seems to be fastest for numpy. This is using numpy 1.8 and python 2.7.6.

In this test in1d was fastest, however 10 in a look cleaner:

a = arange(0,99999,3)
%timeit 10 in a
%timeit in1d(a, 10)

10000 loops, best of 3: 150 µs per loop
10000 loops, best of 3: 61.9 µs per loop

Constructing a set is slower than calling in1d, but checking if the value exists is a bit faster:

s = set(range(0, 99999, 3))
%timeit 10 in s

10000000 loops, best of 3: 47 ns per loop

Explanation from the Preshing on Programming blog:

It’s handy when you have two related operations which you’d like to execute as a pair, with a block of code in between. The classic example is opening a file, manipulating the file, then closing it:

 with open('output.txt', 'w') as f:
     f.write('Hi there!')

The above with statement will automatically close the file after the nested block of code. (Continue reading to see exactly how the close occurs.) The advantage of using a with statement is that it is guaranteed to close the file no matter how the nested block exits. If an exception occurs before the end of the block, it will close the file before the exception is caught by an outer exception handler. If the nested block were to contain a return statement, or a continue or break statement, the with statement would automatically close the file in those cases, too.

Performance wise there is no point to keep non clustered indexes during this as they will get re-updated on drop and create. If it is a big data set you should consider renaming the table (if possible , any security settings on it?), re-creating an empty table with the correct keys migrate all data there. You have to make sure you have enough space for this.

It that code is on the client then you have many trips to the server so to eliminate that.

Insert all the data into a temportary table say T with the same structure as myFoo

Then

insert myFoo
  select *
     from t
       where t.primary_key not in ( select primary_key from myFoo) 

This should work on other databases as well - I have done this on Sybase

It is not the best if very few of the new data is to be inserted as you have copied all the data over the wire.

String double_string = "100.215";
Double double = Double.parseDouble(double_string);

In the shell, you can't execute more than one statement at a time:

>>> x = 5
y = 6
SyntaxError: multiple statements found while compiling a single statement

You need to execute them one by one:

>>> x = 5
>>> y = 6
>>>

When you see multiple statements are being declared, that means you're seeing a script, which will be executed later. But in the interactive interpreter, you can't do more than one statement at a time.

Here is an easy and convenient way of using something similar to the Java map:

var map= {
    'map_name_1': map_value_1,
    'map_name_2': map_value_2,
    'map_name_3': map_value_3,
    'map_name_4': map_value_4
    }

And to get the value:

alert( map['map_name_1'] );    // fives the value of map_value_1

......  etc  .....

In the Windows Command Prompt the ^ is used to escape the next character on the command line. (Like \ is used in strings.) Characters that need to be used in the command line as they are should have a ^ prefixed to them, hence that's why it works for the newline.

For reference the characters that need escaping (if specified as command arguments and not within quotes) are: &|()

So the equivalent of your linux example would be (the More? being a prompt):

C:\> dir ^
More? C:\Windows

$user->data is an array of objects. Each element in the array has a name and value property (as well as others).

Try putting the 2nd foreach inside the 1st.

foreach($user->data as $mydata)
{
    echo $mydata->name . "\n";
    foreach($mydata->values as $values)
    {
        echo $values->value . "\n";
    }
}

WITH UPD AS (UPDATE TEST_TABLE SET SOME_DATA = 'Joe' WHERE ID = 2 
RETURNING ID),
INS AS (SELECT '2', 'Joe' WHERE NOT EXISTS (SELECT * FROM UPD))
INSERT INTO TEST_TABLE(ID, SOME_DATA) SELECT * FROM INS

Tested on Postgresql 9.3

For java 7 and up:

Path path = Paths.get("/your/path/string");
Files.createDirectories(path);

It seems unnecessary to check for existence of the dir or file before creating, from createDirectories javadocs:

Creates a directory by creating all nonexistent parent directories first. Unlike the createDirectory method, an exception is not thrown if the directory could not be created because it already exists. The attrs parameter is optional file-attributes to set atomically when creating the nonexistent directories. Each file attribute is identified by its name. If more than one attribute of the same name is included in the array then all but the last occurrence is ignored.

If this method fails, then it may do so after creating some, but not all, of the parent directories.

[function.fopen]: failed to open stream

If you have access to your php.ini file, try enabling Fopen. Find the respective line and set it to be "on": & if in wp e.g localhost/wordpress/function.fopen in the php.ini :

allow_url_fopen = off
should bee this 
allow_url_fopen = On

And add this line below it:
allow_url_include = off
should bee this 
allow_url_include = on

Try this code its working Firefox, Chrome, IE

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">

I understand that there is a 4000 max set for NVARCHAR(MAX)

Your understanding is wrong. nvarchar(max) can store up to (and beyond sometimes) 2GB of data (1 billion double byte characters).

From nchar and nvarchar in Books online the grammar is

nvarchar [ ( n | max ) ]

The | character means these are alternatives. i.e. you specify either n or the literal max.

If you choose to specify a specific n then this must be between 1 and 4,000 but using max defines it as a large object datatype (replacement for ntext which is deprecated).

In fact in SQL Server 2008 it seems that for a variable the 2GB limit can be exceeded indefinitely subject to sufficient space in tempdb (Shown here)

Regarding the other parts of your question

Truncation when concatenating depends on datatype.

1. varchar(n) + varchar(n) will truncate at 8,000 characters.
2. nvarchar(n) + nvarchar(n) will truncate at 4,000 characters.
3. varchar(n) + nvarchar(n) will truncate at 4,000 characters. nvarchar has higher precedence so the result is nvarchar(4,000)
4. [n]varchar(max) + [n]varchar(max) won't truncate (for < 2GB).
5. varchar(max) + varchar(n) won't truncate (for < 2GB) and the result will be typed as varchar(max).
6. varchar(max) + nvarchar(n) won't truncate (for < 2GB) and the result will be typed as nvarchar(max).
7. nvarchar(max) + varchar(n) will first convert the varchar(n) input to nvarchar(n) and then do the concatenation. If the length of the varchar(n) string is greater than 4,000 characters the cast will be to nvarchar(4000) and truncation will occur.

Datatypes of string literals

If you use the N prefix and the string is <= 4,000 characters long it will be typed as nvarchar(n) where n is the length of the string. So N'Foo' will be treated as nvarchar(3) for example. If the string is longer than 4,000 characters it will be treated as nvarchar(max)

If you don't use the N prefix and the string is <= 8,000 characters long it will be typed as varchar(n) where n is the length of the string. If longer as varchar(max)

For both of the above if the length of the string is zero then n is set to 1.

Newer syntax elements.

1. The CONCAT function doesn't help here

DECLARE @A5000 VARCHAR(5000) = REPLICATE('A',5000);

SELECT DATALENGTH(@A5000 + @A5000), 
       DATALENGTH(CONCAT(@A5000,@A5000));

The above returns 8000 for both methods of concatenation.

2. Be careful with +=

DECLARE @A VARCHAR(MAX) = '';

SET @A+= REPLICATE('A',5000) + REPLICATE('A',5000)

DECLARE @B VARCHAR(MAX) = '';

SET @B = @B + REPLICATE('A',5000) + REPLICATE('A',5000)


SELECT DATALENGTH(@A), 
       DATALENGTH(@B);`

Returns

-------------------- --------------------
8000                 10000

Note that @A encountered truncation.

How to resolve the problem you are experiencing.

You are getting truncation either because you are concatenating two non max datatypes together or because you are concatenating a varchar(4001 - 8000) string to an nvarchar typed string (even nvarchar(max)).

To avoid the second issue simply make sure that all string literals (or at least those with lengths in the 4001 - 8000 range) are prefaced with N.

To avoid the first issue change the assignment from

DECLARE @SQL NVARCHAR(MAX);
SET @SQL = 'Foo' + 'Bar' + ...;

To

DECLARE @SQL NVARCHAR(MAX) = ''; 
SET @SQL = @SQL + N'Foo' + N'Bar'

so that an NVARCHAR(MAX) is involved in the concatenation from the beginning (as the result of each concatenation will also be NVARCHAR(MAX) this will propagate)

Avoiding truncation when viewing

Make sure you have "results to grid" mode selected then you can use

select @SQL as [processing-instruction(x)] FOR XML PATH 

The SSMS options allow you to set unlimited length for XML results. The processing-instruction bit avoids issues with characters such as < showing up as <.

A trap is an exception in a user process. It's caused by division by zero or invalid memory access. It's also the usual way to invoke a kernel routine (a system call) because those run with a higher priority than user code. Handling is synchronous (so the user code is suspended and continues afterwards). In a sense they are "active" - most of the time, the code expects the trap to happen and relies on this fact.

An interrupt is something generated by the hardware (devices like the hard disk, graphics card, I/O ports, etc). These are asynchronous (i.e. they don't happen at predictable places in the user code) or "passive" since the interrupt handler has to wait for them to happen eventually.

You can also see a trap as a kind of CPU-internal interrupt since the handler for trap handler looks like an interrupt handler (registers and stack pointers are saved, there is a context switch, execution can resume in some cases where it left off).

Based on this forum post: https://groups.google.com/forum/#!topic/ggplot2/mK9DR3dKIBU

Sounds like the easiest thing to do is to add a line break (\n) before your x axis, and after your y axis labels. Seems a lot easier (although dumber) than the solutions posted above.

ggplot(mpg, aes(cty, hwy)) + 
    geom_point() + 
    xlab("\nYour_x_Label") + ylab("Your_y_Label\n")

Hope that helps!

TL;DR Remember, all git branches are themselves used for tracking the history of a set of files. Therefore, isn't every branch actually a "tracking branch", because that's what these branches are used for: to track the history of files over time. Thus we should probably be calling normal git "branches", "tracking-branches", but we don't. Instead we shorten their name to just "branches".

So that's partly why the term "tracking-branches" is so terribly confusing: to the uninitiated it can easily mean 2 different things.

In git the term "Tracking-branch" is a short name for the more complete term: "Remote-tracking-branch".

It's probably better at first if you substitute the more formal terms until you get more comfortable with these concepts.

Let's rephrase your question to this:

What is a "Remote-tracking-branch?"

The key word here is 'Remote', so skip down to where you get confused and I'll describe what a Remote Tracking branch is and how it's used.

To better understand git terminology, including branches and tracking, which can initially be very confusing, I think it's easiest if you first get crystal clear on what git is and the basic structure of how it works. Without a solid understand like this I promise you'll get lost in the many details, as git has lots of complexity; (translation: lots of people use it for very important things).

The following is an introduction/overview, but you might find this excellent article also informative.

WHAT GIT IS, AND WHAT IT'S FOR

A git repository is like a family photo album: It holds historical snapshots showing how things were in past times. A "snapshot" being a recording of something, at a given moment in time.

A git repository is not limited to holding human family photos. It, rather can be used to record and organize anything that is evolving or changing over time.

The basic idea is to create a book so we can easily look backwards in time,

• to compare past times, with now, or other moments in time, and
• to re-create the past.

When you get mired down in the complexity and terminology, try to remember that a git repository is first and foremost, a repository of snapshots, and just like a photo album, it's used to both store and organize these snapshots.

SNAPSHOTS AND TRACKING

tracked - to follow a person or animal by looking for proof that they have been somewhere (dictionary.cambridge.org)

In git, "your project" refers to a directory tree of files (one or more, possibly organized into a tree structure using sub-directories), which you wish to keep a history of.

Git, via a 3 step process, records a "snapshot" of your project's directory tree at a given moment in time.

Each git snapshot of your project, is then organized by "links" pointing to previous snapshots of your project.

One by one, link-by-link, we can look backwards in time to find any previous snapshot of you, or your heritage.

For example, we can start with today's most recent snapshot of you, and then using a link, seek backwards in time, for a photo of you taken perhaps yesterday or last week, or when you were a baby, or even who your mother was, etc.

This is refereed to as "tracking; in this example it is tracking your life, or seeing where you have left a footprint, and where you have come from.

COMMITS

A commit is similar to one page in your photo album with a single snapshot, in that its not just the snapshot contained there, but also has the associated meta information about that snapshot. It includes:

• an address or fixed place where we can find this commit, similar to its page number,
• one snapshot of your project (of your file directory tree) at a given moment in time,
• a caption or comment saying what the snapshot is of, or for,
• the date and time of that snapshot,
• who took the snapshot, and finally,
• one, or more, links backwards in time to previous, related snapshots like to yesterday's snapshot, or to our parent or parents. In other words "links" are similar to pointers to the page numbers of other, older photos of myself, or when I am born to my immediate parents.

A commit is the most important part of a well organized photo album.

THE FAMILY TREE OVER TIME, WITH BRANCHES AND MERGES

Disambiguation: "Tree" here refers not to a file directory tree, as used above, but rather to a family tree of related parent and child commits over time.

The git family tree structure is modeled on our own, human family trees.

In what follows to help understand links in a simple way, I'll refer to:

• a parent-commit as simply a "parent", and
• a child-commit as simply a "child" or "children" if plural.

You should understand this instinctively, as it is based on the tree of life:

• A parent might have one or more children pointing back in time at them, and
• children always have one or more parents they point to.

Thus all commits except brand new commits, (you could say "juvenile commits"), have one or more children pointing back at them.

• With no children are pointing to a parent, then this commit is only a "growing tip", or where the next child will be born from.

• With just one child pointing at a parent, this is just a simple, single parent <-- child relationship.

Line diagram of a simple, single parent chain linking backwards in time:

(older) ... <--link1-- Commit1 <--link2-- Commit2 <--link3-- Commit3 (newest)

BRANCHES

branch - A "branch" is an active line of development. The most recent commit on a branch is referred to as the tip of that branch. The tip of the branch is referenced by a branch head, which moves forward as additional development is done on the branch. A single Git repository can track an arbitrary number of branches, but your working tree is associated with just one of them (the "current" or "checked out" branch), and HEAD points to that branch. (gitglossary)

A git branch also refers to two things:

• a name given to a growing tip, (an identifier), and
• the actual branch in the graph of links between commits.

More than one child pointing --at a--> parent, is what git calls "branching".

NOTE: In reality any child, of any parent, weather first, second, or third, etc., can be seen as their own little branch, with their own growing tip. So a branch is not necessarily a long thing with many nodes, rather it is a little thing, created with just one or more commits from a given parent.

The first child of a parent might be said to be part of that same branch, whereas the successive children of that parent are what are normally called "branches".

In actuality, all children (not just the first) branch from it's parent, or you could say link, but I would argue that each link is actually the core part of a branch.

Formally, a git "branch" is just a name, like 'foo' for example, given to a specific growing tip of a family hierarchy. It's one type of what they call a "ref". (Tags and remotes which I'll explain later are also refs.)

ref - A name that begins with refs/ (e.g. refs/heads/master) that points to an object name or another ref (the latter is called a symbolic ref). For convenience, a ref can sometimes be abbreviated when used as an argument to a Git command; see gitrevisions(7) for details. Refs are stored in the repository.

The ref namespace is hierarchical. Different subhierarchies are used for different purposes (e.g. the refs/heads/ hierarchy is used to represent local branches). There are a few special-purpose refs that do not begin with refs/. The most notable example is HEAD. (gitglossary)

(You should take a look at the file tree inside your .git directory. It's where the structure of git is saved.)

So for example, if your name is Tom, then commits linked together that only include snapshots of you, might be the branch we name "Tom".

So while you might think of a tree branch as all of it's wood, in git a branch is just a name given to it's growing tips, not to the whole stick of wood leading up to it.

The special growing tip and it's branch which an arborist (a guy who prunes fruit trees) would call the "central leader" is what git calls "master".

The master branch always exists.

Line diagram of: Commit1 with 2 children (or what we call a git "branch"):

                parent      children

                        +-- Commit <-- Commit <-- Commit (Branch named 'Tom')
                       /
                      v
(older) ... <-- Commit1 <-- Commit                       (Branch named 'master')    

Remember, a link only points from child to parent. There is no link pointing the other way, i.e. from old to new, that is from parent to child.

So a parent-commit has no direct way to list it's children-commits, or in other words, what was derived from it.

MERGING

Children have one or more parents.

• With just one parent this is just a simple parent <-- child commit.

• With more than one parent this is what git calls "merging". Each child can point back to more than one parent at the same time, just as in having both a mother AND father, not just a mother.

Line diagram of: Commit2 with 2 parents (or what we call a git "merge", i.e. Procreation from multiple parents):

                parents     child

           ... <-- Commit
                        v
                         \
(older) ... <-- Commit1 <-- Commit2  

REMOTE

This word is also used to mean 2 different things:

• a remote repository, and
• the local alias name for a remote repository, i.e. a name which points using a URL to a remote repository.

remote repository - A repository which is used to track the same project but resides somewhere else. To communicate with remotes, see fetch or push. (gitglossary)

(The remote repository can even be another git repository on our own computer.) Actually there are two URLS for each remote name, one for pushing (i.e. uploading commits) and one for pulling (i.e. downloading commits) from that remote git repository.

A "remote" is a name (an identifier) which has an associated URL which points to a remote git repository. (It's been described as an alias for a URL, although it's more than that.)

You can setup multiple remotes if you want to pull or push to multiple remote repositories.

Though often you have just one, and it's default name is "origin" (meaning the upstream origin from where you cloned).

origin - The default upstream repository. Most projects have at least one upstream project which they track. By default origin is used for that purpose. New upstream updates will be fetched into remote-tracking branches named origin/name-of-upstream-branch, which you can see using git branch -r. (gitglossary)

Origin represents where you cloned the repository from.
That remote repository is called the "upstream" repository, and your cloned repository is called the "downstream" repository.

upstream - In software development, upstream refers to a direction toward the original authors or maintainers of software that is distributed as source code wikipedia

upstream branch - The default branch that is merged into the branch in question (or the branch in question is rebased onto). It is configured via branch..remote and branch..merge. If the upstream branch of A is origin/B sometimes we say "A is tracking origin/B". (gitglossary)

This is because most of the water generally flows down to you.
From time to time you might push some software back up to the upstream repository, so it can then flow down to all who have cloned it.

REMOTE TRACKING BRANCH

A remote-tracking-branch is first, just a branch name, like any other branch name.

It points at a local growing tip, i.e. a recent commit in your local git repository.

But note that it effectively also points to the same commit in the remote repository that you cloned the commit from.

remote-tracking branch - A ref that is used to follow changes from another repository. It typically looks like refs/remotes/foo/bar (indicating that it tracks a branch named bar in a remote named foo), and matches the right-hand-side of a configured fetch refspec. A remote-tracking branch should not contain direct modifications or have local commits made to it. (gitglossary)

Say the remote you cloned just has 2 commits, like this: parent42 <== child-of-4, and you clone it and now your local git repository has the same exact two commits: parent4 <== child-of-4.
Your remote tracking branch named origin now points to child-of-4.

Now say that a commit is added to the remote, so it looks like this: parent42 <== child-of-4 <== new-baby. To update your local, downstream repository you'll need to fetch new-baby, and add it to your local git repository. Now your local remote-tracking-branch points to new-baby. You get the idea, the concept of a remote-tracking-branch is simply to keep track of what had previously been the tip of a remote branch that you care about.

TRACKING IN ACTION

First we begin tracking a file with git.

Here are the basic commands involved with file tracking:

$ mkdir mydir &&  cd mydir &&  git init             # create a new git repository

$ git branch                                        # this initially reports no branches
                                                    #  (IMHO this is a bug!)

$ git status -bs       # -b = branch; -s = short    # master branch is empty
## No commits yet on master

# ...
$ touch foo                                         # create a new file

$ vim foo                                           # modify it (OPTIONAL)


$ git add         foo; commit -m 'your description'  # start tracking foo 
$ git rm  --index foo; commit -m 'your description'  # stop  tracking foo 
$ git rm          foo; commit -m 'your description'  # stop  tracking foo & also delete foo

REMOTE TRACKING IN ACTION

$ git pull    # Essentially does:  get fetch; git merge    # to update our clone

There is much more to learn about fetch, merge, etc, but this should get you off in the right direction I hope.

Quoting part of @Jatin answer with some modifications,

use this in your where statement:

    SELECT * FROM .... etc.
        Where 
         REPLACE

        (REPLACE

        '1', ''),
        '2', ''),
        '3', ''),
        '4', ''),
        '5', ''),
        '6', ''),
        '7', ''),
        '8', ''),
        '9', '') = P_SEARCH_KEY

will also work

It's easy to define one yourself. That's the power of JavaScript.

if(!Array.prototype.last) {
    Array.prototype.last = function() {
        return this[this.length - 1];
    }
}

var arr = [1, 2, 5];
arr.last(); // 5

However, this may cause problems with 3rd-party code which (incorrectly) uses for..in loops to iterate over arrays.

However, if you are not bound with browser support problems, then using the new ES5 syntax to define properties can solve that issue, by making the function non-enumerable, like so:

Object.defineProperty(Array.prototype, 'last', {
    enumerable: false,
    configurable: true,
    get: function() {
        return this[this.length - 1];
    },
    set: undefined
});

var arr = [1, 2, 5];
arr.last; // 5

I created this method to let use it not only on constructors but in methods:

My constructor:

function __construct() {
    $paramsNumber=func_num_args();
    if($paramsNumber==0){
        //do something
    }else{
        $this->overload('__construct',func_get_args());
    }
}

My doSomething method:

public function doSomething() {
    $paramsNumber=func_num_args();
    if($paramsNumber==0){
        //do something
    }else{
        $this->overload('doSomething',func_get_args());
    }
}

Both works with this simple method:

public function overloadMethod($methodName,$params){
    $paramsNumber=sizeof($params);
    //methodName1(), methodName2()...
    $methodNameNumber =$methodName.$paramsNumber;
    if (method_exists($this,$methodNameNumber)) {
        call_user_func_array(array($this,$methodNameNumber),$params);
    }
}

So you can declare

__construct1($arg1), __construct2($arg1,$arg2)...

or

methodName1($arg1), methodName2($arg1,$arg2)...

and so on :)

And when using:

$myObject =  new MyClass($arg1, $arg2,..., $argN);

it will call __constructN, where you defined N args

then $myObject -> doSomething($arg1, $arg2,..., $argM)

it will call doSomethingM, , where you defined M args;

In KitKat you can use the Storage Access Framework.

Storage Access Framework / Writing a Client App

We can use various approaches to rename the column name.

First, let create a simple DataFrame.

df = spark.createDataFrame([("x", 1), ("y", 2)], 
                                  ["col_1", "col_2"])

Now let's try to rename col_1 to col_3. PFB a few approaches to do the same.

# Approach - 1 : using withColumnRenamed function.
df.withColumnRenamed("col_1", "col_3").show()

# Approach - 2 : using alias function.
df.select(df["col_1"].alias("col3"), "col_2").show()

# Approach - 3 : using selectExpr function.
df.selectExpr("col_1 as col_3", "col_2").show()

# Rename all columns
# Approach - 4 : using toDF function. Here you need to pass the list of all columns present in DataFrame.
df.toDF("col_3", "col_2").show()

Here is the output.

+-----+-----+
|col_3|col_2|
+-----+-----+
|    x|    1|
|    y|    2|
+-----+-----+

I hope this helps.

Ran into a issue with the HTTPClient, even with the suggestions still could not get it to authenticate. Turns out I needed a trailing '/' in my relative path.

i.e.

var result = await _client.GetStringAsync(_awxUrl + "api/v2/inventories/?name=" + inventoryName);

var result = await _client.PostAsJsonAsync(_awxUrl + "api/v2/job_templates/" + templateId+"/launch/" , new {
                inventory = inventoryId
            });

x is already integer(x=0) and again you trying to make x again integer and also you gave indexing which is beyound the limit because x already has only one indexing (0) and you are trying to give indexing same as age so thats why you get this error. use this simple code

name1 = input("What's your name? ")
age1 = int(input ("how old are you?" ))
x=0
twentyone = str(21-age1)
print("Hi, " +name1+ " you will be 21 in: " + twentyone + " years.")

InputStream is;

try {
    is = new FileInputStream("c://filename");

    is.close(); 
} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

return is;

Solution for R to determine direction and reverse if clockwise (found it necessary for owin objects):

coords <- cbind(x = c(5,6,4,1,1),y = c(0,4,5,5,0))
a <- numeric()
for (i in 1:dim(coords)[1]){
  #print(i)
  q <- i + 1
  if (i == (dim(coords)[1])) q <- 1
  out <- ((coords[q,1]) - (coords[i,1])) * ((coords[q,2]) + (coords[i,2]))
  a[q] <- out
  rm(q,out)
} #end i loop

rm(i)

a <- sum(a) #-ve is anti-clockwise

b <- cbind(x = rev(coords[,1]), y = rev(coords[,2]))

if (a>0) coords <- b #reverses coords if polygon not traced in anti-clockwise direction

Another option would be file_get_contents():

// $xml_str = your xml
// $url = target url

$post_data = array('xml' => $xml_str);
$stream_options = array(
    'http' => array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded' . "\r\n",
        'content' =>  http_build_query($post_data)));

$context  = stream_context_create($stream_options);
$response = file_get_contents($url, null, $context);

Before trying to delete/rename any file, you must ensure that all the readers or writers (for ex: BufferedReader/InputStreamReader/BufferedWriter) are properly closed.

When you try to read/write your data from/to a file, the file is held by the process and not released until the program execution completes. If you want to perform the delete/rename operations before the program ends, then you must use the close() method that comes with the java.io.* classes.

replace "150x150" with 720x720 and remove /vp/ from the link.it should work.

This seems to provide the info on Windows:

1.) Open a windows command prompt.

2.) Key in: java -XshowSettings:all and hit ENTER.

3.) A lot of information will be displayed on the command window. Scroll up until you find the string: sun.arch.data.model.

4.) If it says sun.arch.data.model = 32, your VM is 32 bit. If it says sun.arch.data.model = 64, your VM is 64 bit.

Answering this old question (for others which may help)

Configuring your httpd conf correctly will make the problem solved. Install any httpd server, if you don't have one.

Listing my config here.

[smilyface@box002 ~]$ cat /etc/httpd/conf/httpd.conf | grep shirts | grep -v "#"

        ProxyPass /shirts-service http://local.box002.com:16743/shirts-service
        ProxyPassReverse /shirts-service http://local.box002.com:16743/shirts-service
        ProxyPass /shirts http://local.box002.com:16443/shirts
        ProxyPassReverse /shirts http://local.box002.com:16443/shirts
        ...
        ...
        ...

edit the file as above and then restart httpd as below

[smilyface@box002 ~]$ sudo service httpd restart

And then request with with https will work without exception.
Also request with http will forward to https ! No worries.

Use DBNull.Value.Equals on the object without converting it to a string.

Here's an example:

   else
   {
      //null
   }

I'm going to go against the general wisdom here that std::copy will have a slight, almost imperceptible performance loss. I just did a test and found that to be untrue: I did notice a performance difference. However, the winner was std::copy.

I wrote a C++ SHA-2 implementation. In my test, I hash 5 strings using all four SHA-2 versions (224, 256, 384, 512), and I loop 300 times. I measure times using Boost.timer. That 300 loop counter is enough to completely stabilize my results. I ran the test 5 times each, alternating between the memcpy version and the std::copy version. My code takes advantage of grabbing data in as large of chunks as possible (many other implementations operate with char / char *, whereas I operate with T / T * (where T is the largest type in the user's implementation that has correct overflow behavior), so fast memory access on the largest types I can is central to the performance of my algorithm. These are my results:

Time (in seconds) to complete run of SHA-2 tests

std::copy   memcpy  % increase
6.11        6.29    2.86%
6.09        6.28    3.03%
6.10        6.29    3.02%
6.08        6.27    3.03%
6.08        6.27    3.03%

Total average increase in speed of std::copy over memcpy: 2.99%

My compiler is gcc 4.6.3 on Fedora 16 x86_64. My optimization flags are -Ofast -march=native -funsafe-loop-optimizations.

Code for my SHA-2 implementations.

I decided to run a test on my MD5 implementation as well. The results were much less stable, so I decided to do 10 runs. However, after my first few attempts, I got results that varied wildly from one run to the next, so I'm guessing there was some sort of OS activity going on. I decided to start over.

Same compiler settings and flags. There is only one version of MD5, and it's faster than SHA-2, so I did 3000 loops on a similar set of 5 test strings.

These are my final 10 results:

Time (in seconds) to complete run of MD5 tests

std::copy   memcpy      % difference
5.52        5.56        +0.72%

5.57        5.53        -0.72%
5.57        5.52        -0.91%

5.59        5.57        -0.36%
5.57        5.56        -0.18%

Total average decrease in speed of std::copy over memcpy: 0.11%

Code for my MD5 implementation

These results suggest that there is some optimization that std::copy used in my SHA-2 tests that std::copy could not use in my MD5 tests. In the SHA-2 tests, both arrays were created in the same function that called std::copy / memcpy. In my MD5 tests, one of the arrays was passed in to the function as a function parameter.

I did a little bit more testing to see what I could do to make std::copy faster again. The answer turned out to be simple: turn on link time optimization. These are my results with LTO turned on (option -flto in gcc):

Time (in seconds) to complete run of MD5 tests with -flto

std::copy   memcpy      % difference
5.54        5.57        +0.54%
5.50        5.53        +0.54%
5.54        5.58        +0.72%
5.50        5.57        +1.26%
5.54        5.58        +0.72%
5.54        5.57        +0.54%
5.54        5.56        +0.36%
5.54        5.58        +0.72%
5.51        5.58        +1.25%
5.54        5.57        +0.54%

Total average increase in speed of std::copy over memcpy: 0.72%

In summary, there does not appear to be a performance penalty for using std::copy. In fact, there appears to be a performance gain.

Explanation of results

So why might std::copy give a performance boost?

First, I would not expect it to be slower for any implementation, as long as the optimization of inlining is turned on. All compilers inline aggressively; it is possibly the most important optimization because it enables so many other optimizations. std::copy can (and I suspect all real world implementations do) detect that the arguments are trivially copyable and that memory is laid out sequentially. This means that in the worst case, when memcpy is legal, std::copy should perform no worse. The trivial implementation of std::copy that defers to memcpy should meet your compiler's criteria of "always inline this when optimizing for speed or size".

However, std::copy also keeps more of its information. When you call std::copy, the function keeps the types intact. memcpy operates on void *, which discards almost all useful information. For instance, if I pass in an array of std::uint64_t, the compiler or library implementer may be able to take advantage of 64-bit alignment with std::copy, but it may be more difficult to do so with memcpy. Many implementations of algorithms like this work by first working on the unaligned portion at the start of the range, then the aligned portion, then the unaligned portion at the end. If it is all guaranteed to be aligned, then the code becomes simpler and faster, and easier for the branch predictor in your processor to get correct.

Premature optimization?

std::copy is in an interesting position. I expect it to never be slower than memcpy and sometimes faster with any modern optimizing compiler. Moreover, anything that you can memcpy, you can std::copy. memcpy does not allow any overlap in the buffers, whereas std::copy supports overlap in one direction (with std::copy_backward for the other direction of overlap). memcpy only works on pointers, std::copy works on any iterators (std::map, std::vector, std::deque, or my own custom type). In other words, you should just use std::copy when you need to copy chunks of data around.

Use string's split() method.

The typical command is:

docker container ls -f 'status=exited'

However, this will only list one of the possible non-running statuses. Here's a list of all possible statuses:

• created
• restarting
• running
• removing
• paused
• exited
• dead

You can filter on multiple statuses by passing multiple filters on the status:

docker container ls -f 'status=exited' -f 'status=dead' -f 'status=created'

If you are integrating this with an automatic cleanup script, you can chain one command to another with some bash syntax, output just the container id's with -q, and you can also limit to just the containers that exited successfully with an exit code filter:

docker container rm $(docker container ls -q -f 'status=exited' -f 'exited=0')

For more details on filters you can use, see Docker's documentation: https://docs.docker.com/engine/reference/commandline/ps/#filtering

The confusing thing might be that there are a few places to start the cmd from. In my case I ran cmd from windows explorer and the environment variables did not change while when starting cmd from the "run" (windows key + r) the environment variables were changed.

In my case I just had to kill the windows explorer process from the task manager and then restart it again from the task manager.

Once I did this I had access to the new environment variable from a cmd that was spawned from windows explorer.

Be carefull that the page does not contain any empty component which has "required" attribute as "true" before your selectOneMenu component running.
If you use a component such as

<p:inputText label="Nm:" id="id_name" value="#{ myHelper.name}" required="true"/>

then,

<p:selectOneMenu .....></p:selectOneMenu>

and forget to fill the required component, ajax listener of selectoneMenu cannot be executed.

I use this code for VB:

<asp:TemplateField HeaderText="Active" SortExpression="Active">
    <ItemTemplate><%#IIf(Boolean.Parse(Eval("Active").ToString()), "Yes", "No")%></ItemTemplate>
</asp:TemplateField>

And this should work for C# (untested):

<asp:TemplateField HeaderText="Active" SortExpression="Active">
    <ItemTemplate><%# (Boolean.Parse(Eval("Active").ToString())) ? "Yes" : "No" %></ItemTemplate>
</asp:TemplateField>

Just do below code it's working absolute fine

$(".addproduct").on('click', function(event){
    event.stopPropagation();
    event.stopImmediatePropagation();
    getRecord();
});


function getRecord(){
   $(".addproduct").each(function () {
       console.log("test");
       });

}

Using Stopwatch class we can achieve it from System.Diagnostics.

Stopwatch stopwatch  = new Stopwatch();
stopwatch.Start();
stopwatch.Stop();
Debug.WriteLine(stopwatch.ElapsedMilliseconds);

Document Object Model (DOM), a programming interface specification being developed by the World Wide Web Consortium (W3C), lets a programmer create and modify HTML pages and XML documents as full-fledged program objects.

From: https://developer.android.com/tools/support-library/setup.html#libs-with-res

Adding libraries with resources To add a Support Library with resources (such as v7 appcompat for action bar) to your application project:

Using Eclipse

Create a library project based on the support library code:

• Make sure you have downloaded the Android Support Library using the SDK Manager.

• Create a library project and ensure the required JAR files are included in the project's build path:

• Select File > Import.

• Select Existing Android Code Into Workspace and click Next.

• Browse to the SDK installation directory and then to the Support Library folder. For example, if you are adding the appcompat project, browse to /extras/android/support/v7/appcompat/.

• Click Finish to import the project. For the v7 appcompat project, you should now see a new project titled android-support-v7-appcompat.

• In the new library project, expand the libs/ folder, right-click each .jar file and select Build

• Path > Add to Build Path. For example, when creating the the v7 appcompat project, add both the android-support-v4.jar and android-support-v7-appcompat.jar files to the build path.

• Right-click the library project folder and select Build Path > Configure Build Path.

• In the Order and Export tab, check the .jar files you just added to the build path, so they are available to projects that depend on this library project. For example, the appcompat project requires you to export both the android-support-v4.jar and android-support-v7-appcompat.jar files.

• Uncheck Android Dependencies.

• Click OK to complete the changes.

• You now have a library project for your selected Support Library that you can use with one or more application projects.

• Add the library to your application project:

• In the Project Explorer, right-click your project and select Properties.

• In the category panel on the left side of the dialog, select Android.

• In the Library pane, click the Add button.

• Select the library project and click OK. For example, the appcompat project should be listed as android-support-v7-appcompat.

• In the properties window, click OK.

I run into this issue too. I was including bootstrap.js AND bootstrap-modal.js. If you already have bootstrap.js, you don't need to include popover.

Here is how I found out a point on a circle with javascript, calculating the angle (degree) from the top of the circle.

  const centreX = 50; // centre x of circle
  const centreY = 50; // centre y of circle
  const r = 20; // radius
  const angleDeg = 45; // degree in angle from top
  const radians = angleDeg * (Math.PI/180);
  const pointY = centreY - (Math.cos(radians) * r); // specific point y on the circle for the angle
  const pointX = centreX + (Math.sin(radians) * r); // specific point x on the circle for the angle

As mentioned, @JsonValue is a good way. But if you don't mind a custom serializer, there's no need to write one for Item but rather one for User -- if so, it'd be as simple as:

public void serialize(Item value, JsonGenerator jgen,
    SerializerProvider provider) throws IOException,
    JsonProcessingException {
  jgen.writeNumber(id);
}

Yet another possibility is to implement JsonSerializable, in which case no registration is needed.

As to error; that is weird -- you probably want to upgrade to a later version. But it is also safer to extend org.codehaus.jackson.map.ser.SerializerBase as it will have standard implementations of non-essential methods (i.e. everything but actual serialization call).

I am following the same tuturial and I had this issue and how I solved is just download the

8.11.4 LTS version

from this link then install it then the command worked just fine!

I found a different solution for this...

Actually, I missed comma separator between two library paths. After adding common it worked for me.

Go to: Project properties -> Linker -> General -> Link Library Dependencies At this path make sure the path of the library is correct.

Previous Code (With Bug - because I forgot to separate two lib paths with comma):

<Link><AdditionalLibraryDirectories>..\..\Build\lib\$(Configuration)**..\..\Build\Release;**%(AdditionalLibraryDirectories)</AdditionalLibraryDirectories>

Code after fix (Just separate libraries with comma):

<Link><AdditionalLibraryDirectories>..\..\Build\lib\$(Configuration)**;..\..\Build\Release;**%(AdditionalLibraryDirectories)</AdditionalLibraryDirectories>

Hope this will help you.

I found 2 things worth mentioning while uploading files using webdav and http web request. First, for the provider I was using, I had to append the filename at the end of the provider url. Ihad to append the port number in the url. And I also set the Request method to PUT instead of POST.

example:

string webdavUrl = "https://localhost:443/downloads/test.pdf";
request.Method = "PUT";

In SQL Server Management Studio you can right click on the database you want to replicate, and select "Script Database as" to have the tool create the appropriate SQL file to replicate that database on another server. You can repeat this process for each table you want to create, and then merge the files into a single SQL file. Don't forget to add a using statement after you create your Database but prior to any table creation.

In more recent versions of SQL Server you can get this in one file in SSMS.

1. Right click a database.
2. Tasks
3. Generate Scripts

This will launch a wizard where you can script the entire database or just portions. There does not appear to be a T-SQL way of doing this.

It should not work on windows (maybe with cygwin ?), but for unix user, you should use the "fcntl" system call. Here is an example in Python. It's mostly the same code if you need to write it in C (same function names)

import time
import fcntl
import os
import signal

FNAME = "/HOME/TOTO/FILETOWATCH"

def handler(signum, frame):
    print "File %s modified" % (FNAME,)

signal.signal(signal.SIGIO, handler)
fd = os.open(FNAME,  os.O_RDONLY)
fcntl.fcntl(fd, fcntl.F_SETSIG, 0)
fcntl.fcntl(fd, fcntl.F_NOTIFY,
            fcntl.DN_MODIFY | fcntl.DN_CREATE | fcntl.DN_MULTISHOT)

while True:
    time.sleep(10000)

After attempting a few of these solutions and not having any success, this is what worked for me:

1. Restart system
2. mysql.server start
3. Success!

I had this error, because i scrolled bottom. Datepicker had wrong top position in fixed. I just use it now like:

$('#myModal').on('show.bs.modal', function (e) {
            $(document).scrollTop(0);
});

and its working fine now.

That should work:

>>> df = pd.DataFrame()
>>> data = pd.DataFrame({"A": range(3)})
>>> df.append(data)
   A
0  0
1  1
2  2

But the append doesn't happen in-place, so you'll have to store the output if you want it:

>>> df
Empty DataFrame
Columns: []
Index: []
>>> df = df.append(data)
>>> df
   A
0  0
1  1
2  2

You could use sed,

sed 's/.\{4\}$//' <<< "$var"

EXample:

$ var="some string.rtf"
$ var1=$(sed 's/.\{4\}$//' <<< "$var")
$ echo $var1
some string

On Windows timer returns hundredths of a second... Most people just use seconds because on the Macintosh platform timer returns whole numbers.

For C++, there are various type-safe enum techniques available, and some of those (such as the proposed-but-never-submitted Boost.Enum) include support for getting the size of a enum.

The simplest approach, which works in C as well as C++, is to adopt a convention of declaring a ...MAX value for each of your enum types:

enum Folders { FA, FB, FC, Folders_MAX = FC };
ContainerClass *m_containers[Folders_MAX + 1];
....
m_containers[FA] = ...; // etc.

Edit: Regarding { FA, FB, FC, Folders_MAX = FC} versus {FA, FB, FC, Folders_MAX]: I prefer setting the ...MAX value to the last legal value of the enum for a few reasons:

1. The constant's name is technically more accurate (since Folders_MAX gives the maximum possible enum value).
2. Personally, I feel like Folders_MAX = FC stands out from other entries out a bit more (making it a bit harder to accidentally add enum values without updating the max value, a problem Martin York referenced).
3. GCC includes helpful warnings like "enumeration value not included in switch" for code such as the following. Letting Folders_MAX == FC + 1 breaks those warnings, since you end up with a bunch of ...MAX enumeration values that should never be included in switch.

switch (folder) 
{
  case FA: ...;
  case FB: ...;
  // Oops, forgot FC!
}

data.sort(function(a,b) 
{
   return a.val - b.val;
});

AFAIS, no one mentions of atomic reference.

Integer

public void swap(AtomicInteger a, AtomicInteger b){
    a.set(b.getAndSet(a.get()));
}

String

public void swap(AtomicReference<String> a, AtomicReference<String> b){
    a.set(b.getAndSet(a.get()));
}

Looking at the AndroidManifest.xml (link), on line 9:

<activity android:screenOrientation="landscape" android:configChanges="orientation|keyboardHidden" android:name="VncCanvasActivity">

This line specifies the screenOrientation as landscape, but author goes further in overriding any screen orientation changes with configChanges="orientation|keyboardHidden". This points to a overridden function in VncCanvasActivity.java.

If you look at VncCanvasActivity, on line 109 is the overrided function:

@Override
public void onConfigurationChanged(Configuration newConfig) {
  // ignore orientation/keyboard change
  super.onConfigurationChanged(newConfig);
}

The author specifically put a comment to ignore any keyboard or orientation changes.

If you want to change this, you can go back to the AndroidManifest.xml file shown above, and change the line to:

<activity android:screenOrientation="sensor" android:name="VncCanvasActivity">

This should change the program to switch from portrait to landscape when the user rotates the device.

This may work, but might mess up how the GUI looks, depending on how the layout were created. You will have to account for that. Also, depending on how the activities are coded, you may notice that when screen orientation is changed, the values that were filled into any input boxes disappear. This also may have to be handled.

Try this:

str.replace(/\s/g, "X")

You can use case-sensitive or case-insensitive comparison, depending what you need. Case-sensitive is like this:

if ([category isEqualToString:@"Some String"])
{
   // Both strings are equal without respect to their case.
}

Case-insensitive is like this:

if ([category compare:@"Some String" options:NSCaseInsensitiveSearch] == NSOrderedSame)
{
   // Both strings are equal with respect to their case.
}

In your SELECT statement you need to preface your id with the table you want to choose it from.

SELECT tbl_names.id, name, section 
FROM tbl_names
INNER JOIN tbl_section 
   ON tbl_names.id = tbl_section.id

OR

SELECT tbl_section.id, name, section 
FROM tbl_names
INNER JOIN tbl_section 
   ON tbl_names.id = tbl_section.id

If you are accessing Oracle with JDBC (Java) you can use DatabaseMetadata class. If you are accessing Oracle with ADO.NET you can use a similar approach.

If you are accessing Oracle with ODBC, you can use SQLTables function.

Otherwise, if you just need the information in SQLPlus or similar Oracle client, one of the queries already mentioned will do. For instance:

select TABLE_NAME from user_tables

The API changed since this commit, using version 1.4.1 it's now

Assuming you want to reset your PostgreSQL database and set it back up, use:

heroku apps

to list your applications on Heroku. Find the name of your current application (application_name). Then run

heroku config | grep POSTGRESQL

to get the name of your databases. An example could be

HEROKU_POSTGRESQL_WHITE_URL

Finally, given application_name and database_url, you should run

heroku pg:reset `database_url` --confirm `application_name`
heroku run rake db:migrate
heroku restart

To avoid blank line skipping just replace this:

echo !modified! >> %OUTTEXTFILE%

with this:

echo.!modified! >> %OUTTEXTFILE%

An old question, but I'd like to offer my solution anyway. It's based on acceptance that model objects too require some additional functionality while it's awkward to place it within the models.py. Heavy business logic may be written separately depending on personal taste, but I at least like the model to do everything related to itself. This solution also supports those who like to have all the logic placed within models themselves.

As such, I devised a hack that allows me to separate logic from model definitions and still get all the hinting from my IDE.

The advantages should be obvious, but this lists a few that I have observed:

• DB definitions remain just that - no logic "garbage" attached
• Model-related logic is all placed neatly in one place
• All the services (forms, REST, views) have a single access point to logic
• Best of all: I did not have to rewrite any code once I realised that my models.py became too cluttered and had to separate the logic away. The separation is smooth and iterative: I could do a function at a time or entire class or the entire models.py.

I have been using this with Python 3.4 and greater and Django 1.8 and greater.

app/models.py

....
from app.logic.user import UserLogic

class User(models.Model, UserLogic):
    field1 = models.AnyField(....)
    ... field definitions ...

app/logic/user.py

if False:
    # This allows the IDE to know about the User model and its member fields
    from main.models import User

class UserLogic(object):
    def logic_function(self: 'User'):
        ... code with hinting working normally ...

The only thing I can't figure out is how to make my IDE (PyCharm in this case) recognise that UserLogic is actually User model. But since this is obviously a hack, I'm quite happy to accept the little nuisance of always specifying type for self parameter.

The following will order your data depending on both column in descending order.

ORDER BY article_rating DESC, article_time DESC

Right click on your project -> properties -> build path. Add to your build path jar file(s) that have the javax.servlet implemenation. Ite depends on your servlet container or application server what file(s) you need to include, so search for that information.

EDIT: ASIHTTPRequest has been abandoned by the developer. It's still really good IMO, but you should probably look elsewhere now.

I'd highly recommend using the ASIHTTPRequest library if you are handling HTTPS. Even without https it provides a really nice wrapper for stuff like this and whilst it's not hard to do yourself over plain http, I just think the library is nice and a great way to get started.

The HTTPS complications are far from trivial in various scenarios, and if you want to be robust in handling all the variations, you'll find the ASI library a real help.

Two-way binding just means that:

1. When properties in the model get updated, so does the UI.
2. When UI elements get updated, the changes get propagated back to the model.

Backbone doesn't have a "baked-in" implementation of #2 (although you can certainly do it using event listeners). Other frameworks like Knockout do wire up two-way binding automagically.

In Backbone, you can easily achieve #1 by binding a view's "render" method to its model's "change" event. To achieve #2, you need to also add a change listener to the input element, and call model.set in the handler.

Here's a Fiddle with two-way binding set up in Backbone.

Python 3 ints do not have a maximum.

If your purpose is to determine the maximum size of an int in C when compiled the same way Python was, you can use the struct module to find out:

>>> import struct
>>> platform_c_maxint = 2 ** (struct.Struct('i').size * 8 - 1) - 1

If you are curious about the internal implementation details of Python 3 int objects, Look at sys.int_info for bits per digit and digit size details. No normal program should care about these.

This one is similar to @Wilhelm's solution. The loop automates based on a range created by evaluating the populated date column. This was slapped together based strictly on the conversation here and screenshots.

Please note: This assumes that the headers will always be on the same row (row 8). Changing the first row of data (moving the header up/down) will cause the range automation to break unless you edit the range block to take in the header row dynamically. Other assumptions include that VOL and CAPACITY formula column headers are named "Vol" and "Cap" respectively.

Sub Loop3()

Dim dtCnt As Long
Dim rng As Range
Dim frmlas() As String

Application.ScreenUpdating = False

'The following code block sets up the formula output range
dtCnt = Sheets("Loop").Range("A1048576").End(xlUp).Row              'lowest date column populated
endHead = Sheets("Loop").Range("XFD8").End(xlToLeft).Column         'right most header populated
Set rng = Sheets("Loop").Range(Cells(9, 2), Cells(dtCnt, endHead))  'assigns range for automation

ReDim frmlas(1)      'array assigned to formula strings
    'VOL column formula
frmlas(0) = "VOL FORMULA"
    'CAPACITY column formula
frmlas(1) = "CAP FORMULA"

For i = 1 To rng.Columns.count
If rng(0, i).Value = "Vol" Then         'checks for volume formula column
    For j = 1 To rng.Rows.count
        rng(j, i).Formula= frmlas(0)    'inserts volume formula
    Next j
ElseIf rng(0, i).Value = "Cap" Then     'checks for capacity formula column
    For j = 1 To rng.Rows.count
        rng(j, i).Formula = frmlas(1)   'inserts capacity formula
    Next j
End If
Next i

Application.ScreenUpdating = True

End Sub

You need to first create Laravel project and if you already have one you need to go to this project dir using cd command in terminal for example cd myproject.

Example : C:\xampp new\htdocs\project laravel\LaravelProject>php artisan serve

Now you will be able to run any artisan commands, for example running php artisan will display you list of available commands.

The given solution did not work for me, however a similar version did...

This is with a cloned repository, hence the submodule git repos are contained in the top repositories .git dir. All cations are from the top repository:

1. Edit .gitmodules and change the "path =" setting for the submodule in question. (No need to change the label, nor to add this file to index.)

2. Edit .git/modules/name/config and change the "worktree =" setting for the submodule in question

3. run:

   mv submodule newpath/submodule
   git add -u
   git add newpath/submodule
   

I wonder if it makes a difference if the repositories are atomic, or relative submodules, in my case it was relative (submodule/.git is a ref back to topproject/.git/modules/submodule)

This should work

For the first question I think answer would be:

<your DataFrame>.rename(columns={'count':'Total_Numbers'})

or

<your DataFrame>.columns = ['ID', 'Region', 'Total_Numbers']

As for second one I'd say the answer would be no. It's possible to use it like 'df.ID' because of python datamodel:

Attribute references are translated to lookups in this dictionary, e.g., m.x is equivalent to m.dict["x"]

I was having the same error - ImportError: No module named PyQt4.QtGui. Instead of running your python file (which uses PyQt) on the terminal as -

python file_name.py

Run it with sudo privileges -

sudo python file_name.py

This worked for me!

Another Alternative for those who are probing around and/or in interactive mode:

$Error[0].Exception.LoaderExceptions

Note: [0] grabs the most recent Error from the stack

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

Set the styles for class active and hover:

Than you need to make the li active, on the server side. So when you are drawing the menu, you should know which page is loaded and set it to:

 <li class="active">Question</li>
 <li>Tags</li>
 <li>Users</li>

But if you are changing the content without reloading, you cannot change set the active li element on the server, you need to use javascript:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<style>
  .menu{width: 300px; height: 25; font-size: 18px;}
  .menu li{list-style: none; float: left; margin-right: 4px; padding: 5px;}
  .menu li:hover, .menu li.active {
        background-color: #f90;
    }
</style>
</head>
<body>

<ul class="menu">
<li>Item 1</li>
<li class="active">Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
<li>Item 5</li>
<li>Item 6</li>
</ul>

<script type="text/javascript">

var make_button_active = function()
{
  //Get item siblings
  var siblings =($(this).siblings());

  //Remove active class on all buttons
  siblings.each(function (index)
    {
      $(this).removeClass('active');
    }
  )


  //Add the clicked button class
  $(this).addClass('active');
}

//Attach events to menu
$(document).ready(
  function()
  {
    $(".menu li").click(make_button_active);
  }  
)

</script>
</body>

</html>

In addition to solutions proposed, and in case you have a 1D range to 1D array, i prefer to process it through a function like below. The reason is simple: If for any reason your range is reduced to 1 element range, as far as i know the command Range().Value will not return a variant array but just a variant and you will not be able to assign a variant variable to a variant array (previously declared).

I had to convert a variable size range to a double array, and when the range was of 1 cell size, i was not able to use a construct like range().value so i proceed with a function like below.

Public Function Rng2Array(inputRange As Range) As Double()

    Dim out() As Double    
    ReDim out(inputRange.Columns.Count - 1)

    Dim cell As Range
    Dim i As Long
    For i = 0 To inputRange.Columns.Count - 1
        out(i) = inputRange(1, i + 1) 'loop over a range "row"
    Next

    Rng2Array = out  
End Function

You can do this by simply marking it disabled or enabled. You can use this code to do this:

//for disable
$('#fieldName').prop('disabled', true);

//for enable 
$('#fieldName').prop('disabled', false);

or

$('#fieldName').prop('readonly', true);

$('#fieldName').prop('readonly', false);

--- Its better to use prop instead of attr.

Note that the onload event doesn't seem to fire if the iframe is loaded when offscreen. This frequently occurs when using "Open in New Window" /w tabs.

Change the lines

if(nodeValue!=null)
    fop.write(nodeValue.getBytes());

fop.flush();

to

if(nodeValue!=null) {
    fop.write(nodeValue.getBytes());
    fop.write(System.getProperty("line.separator").getBytes());
}

fop.flush();

Update to address your edit:

In order to write each word on a different line, you need to split up your input string and then write each word separately.

private static void GetText(String nodeValue) throws IOException {

    if(!file3.exists()) {
        file3.createNewFile();
    }

    FileOutputStream fop=new FileOutputStream(file3,true);
    if(nodeValue!=null)
        for(final String s : nodeValue.split(" ")){
            fop.write(s.getBytes());
            fop.write(System.getProperty("line.separator").getBytes());
        }
    }

    fop.flush();
    fop.close();

}

How about something like this...

Do While Not rs.EOF
   Debug.Print rs("PictureLocation") & " - " & rs("ID")
   rs.MoveNext
Loop

Use display:none to not show the items, then with JQuery you can use fadeIn() and fadeOut() to hide/unhide the elements.

Since in Javascript a string is a char array, you can access the last character by the length of the string.

var lastChar = myString[myString.length -1];

The most voted answer covers most part but I would like to high light use case point of view. Can kafka do that rabbit mq can do, answer is yes but can rabbit mq do everything that kafka does, the answer is no.

The thing that rabbit mq cannot do that makes kafka apart, is distributed message processing. With this now read back the most voted answer and it will make more sense.

To elaborate, take a use case where you need to create a messaging system that has super high throughput for example "likes" in facebook and You have chosen rabbit mq for that. You created an exchange and queue and a consumer where all publishers (in this case FB users) can publish 'likes' messages. Since your throughput is high, you will create multiple threads in consumer to process messages in parallel but you still bounded by the hardware capacity of the machine where consumer is running. Assuming that one consumer is not sufficient to process all messages - what would you do?

• Can you add one more consumer to queue - no you cant do that.
• Can you create a new queue and bind that queue to exchange that publishes 'likes' message, answer is no cause you will have messages processed twice.

That is the core problem that kafka solves. It lets you create distributed partitions (Queue in rabbit mq) and distributed consumer that talk to each other. That ensures your messages in a topic get processed by consumers distributed in various nodes (Machines).

Kafka brokers ensure that messages get load balanced across all partitions of that topic. Consumer group make sure that all consumer talk to each other and message does not get processed twice.

But in real life you will not face this problem unless your throughput is seriously high because rabbit mq can also process data very fast even with one consumer.
