$('#txtConfirmPassword').keyup(function(){


if($(this).val() != $('#txtNewPassword').val().substr(0,$(this).val().length))
{
 alert('confirm password not match');
}



});

It means something like this:

std::vector<Movie *> movies;

Then you add to the vector as you read lines:

movies.push_back(new Movie(...));

Remember to delete all of the Movie* objects once you are done with the vector.

Please Remember if you want to install python package/libraries for windows,

you should always consider Python unofficial Binaries

Step 1:

Search for your package, download dependent version 2.7 or 3.6 you can find it under Downloads/your_package_version.whl its called python wheel

Step 2:

Now install using pip,

pip install ~/Downloads/your_packae_ver.whl

this will install without any error.

Via using NodeJS (commonJS syntax) I was able to get this type of functionality working, I originally had just a JSON structure inside some external JS file, but I wanted that structure to be more of a Class, with methods that could be decided at run time.

The declaration of 'Executor' in myJSON is not required.

var myJSON = {
    "Hello": "World",
    "Executor": ""
}

module.exports = {
    init: () => { return { ...myJSON, "Executor": (first, last) => { return first + last } } }
}

Your tomcat-users.xml looks good.

Make sure you have the manager/ application inside your $CATALINA_BASE/webapps/

• Linux:

You have to install tomcat-admin package: sudo apt-get install tomcat8-admin (for version 8)

• Windows:

I am using Eclipse. I had to copy the manager/ folder from C:\Program Files\apache-tomcat-8.5.20\webapps to my Eclipse workspace (~\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\webapps\).

I had this error when opening a CSV file and one of the fields had commas embedded in it. The field had quotes around it, and I had cut and paste the read.table with quote="" in it. Once I took quote="" out, the default behavior of read.table took over and killed the problem. So I went from this:

systems <- read.table("http://getfile.pl?test.csv", header=TRUE, sep=",", quote="")

to this:

systems <- read.table("http://getfile.pl?test.csv", header=TRUE, sep=",")

I had a situation where I needed to compare each row of a table with the next row to it, (next here is relative to my problem specification) in the example next row is specified using the order by clause inside the row_number() function.

so I wrote this:

DECLARE @T TABLE (col1 nvarchar(50));

insert into @T VALUES ('A'),('B'),('C'),('D'),('E')

select I1.col1 Instance_One_Col, I2.col1 Instance_Two_Col  from (
 select col1,row_number() over (order by col1) as row_num
 FROM @T
) AS I1
left join (
 select col1,row_number() over (order by col1) as row_num
 FROM @T
) AS I2 on I1.row_num = I2.row_num - 1

after that I can compare each row to the next one as I need

Try this code

The code looks strange because the printf are not in any function blocks.

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

This is how I did it:

$str = file_get_contents("my-code-file.php");
echo "<textarea disabled='true' style='border: none;background-color:white;'>";
echo $str;
echo "</textarea>";

You can simply use unset() to delete an array.

Remember that an array must be unset after the foreach function.

That is the correct event. Maybe it's not wired up correctly?

<TabControl SelectionChanged="TabControl_SelectionChanged">
    <TabItem Header="One"/>
    <TabItem Header="2"/>
    <TabItem Header="Three"/>
</TabControl>

in the codebehind....

private void TabControl_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    int i = 34;
}

if I set a breakpoint on the i = 34 line, it ONLY breaks when i change tabs, even when the tabs have child elements and one of them is selected.

In order to prove that a problem L is NP-complete, we need to do the following steps:

1. Prove your problem L belongs to NP (that is that given a solution you can verify it in polynomial time)
2. Select a known NP-complete problem L'
3. Describe an algorithm f that transforms L' into L
4. Prove that your algorithm is correct (formally: x ? L' if and only if f(x) ? L )
5. Prove that algo f runs in polynomial time

It's easy to create this yourself

In your layout include the following ProgressBar with a specific drawable (note you should get the width from dimensions instead). The max value is important here:

<ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:max="500"
    android:progress="0"
    android:progressDrawable="@drawable/circular" />

Now create the drawable in your resources with the following shape. Play with the radius (you can use innerRadius instead of innerRadiusRatio) and thickness values.

circular (Pre Lollipop OR API Level < 21)

   <shape
        android:innerRadiusRatio="2.3"
        android:shape="ring"
        android:thickness="3.8sp" >
        <solid android:color="@color/yourColor" />
   </shape>

circular ( >= Lollipop OR API Level >= 21)

    <shape
        android:useLevel="true"
        android:innerRadiusRatio="2.3"
        android:shape="ring"
        android:thickness="3.8sp" >
        <solid android:color="@color/yourColor" />
     </shape>

useLevel is "false" by default in API Level 21 (Lollipop) .

Start Animation

Next in your code use an ObjectAnimator to animate the progress field of the ProgessBar of your layout.

ProgressBar progressBar = (ProgressBar) view.findViewById(R.id.progressBar);
ObjectAnimator animation = ObjectAnimator.ofInt(progressBar, "progress", 0, 500); // see this max value coming back here, we animate towards that value
animation.setDuration(5000); // in milliseconds
animation.setInterpolator(new DecelerateInterpolator());
animation.start();

Stop Animation

progressBar.clearAnimation();

P.S. unlike examples above, it give smooth animation.

As nice as "return by value" might be, it's the kind of code that can lead one into error. Consider the following program:

    #include <string>
    #include <vector>
    #include <iostream>
    using namespace std;
    static std::vector<std::string> strings;
    std::vector<std::string> vecFunc(void) { return strings; };
    int main(int argc, char * argv[]){
      // set up the vector of strings to hold however
      // many strings the user provides on the command line
      for(int idx=1; (idx<argc); ++idx){
         strings.push_back(argv[idx]);
      }

      // now, iterate the strings and print them using the vector function
      // as accessor
      for(std::vector<std::string>::interator idx=vecFunc().begin(); (idx!=vecFunc().end()); ++idx){
         cout << "Addr: " << idx->c_str() << std::endl;
         cout << "Val:  " << *idx << std::endl;
      }
    return 0;
    };

• Q: What will happen when the above is executed? A: A coredump.
• Q: Why didn't the compiler catch the mistake? A: Because the program is syntactically, although not semantically, correct.
• Q: What happens if you modify vecFunc() to return a reference? A: The program runs to completion and produces the expected result.
• Q: What is the difference? A: The compiler does not have to create and manage anonymous objects. The programmer has instructed the compiler to use exactly one object for the iterator and for endpoint determination, rather than two different objects as the broken example does.

The above erroneous program will indicate no errors even if one uses the GNU g++ reporting options -Wall -Wextra -Weffc++

If you must produce a value, then the following would work in place of calling vecFunc() twice:

   std::vector<std::string> lclvec(vecFunc());
   for(std::vector<std::string>::iterator idx=lclvec.begin(); (idx!=lclvec.end()); ++idx)...

The above also produces no anonymous objects during iteration of the loop, but requires a possible copy operation (which, as some note, might be optimized away under some circumstances. But the reference method guarantees that no copy will be produced. Believing the compiler will perform RVO is no substitute for trying to build the most efficient code you can. If you can moot the need for the compiler to do RVO, you are ahead of the game.

I would suggest you just write a function to do what you're saying probably using drop (to delete columns) and insert to insert columns at a position. There isn't an existing API function to do what you're describing.

The built-in matrix function has the nice option to enter data byrow. Combine that with an unlist on your source list will give you a matrix. We also need to specify the number of rows so it can break up the unlisted data. That is:

> matrix(unlist(a), byrow=TRUE, nrow=length(a) )
      [,1] [,2] [,3] [,4] [,5] [,6]
 [1,]    1    1    2    3    4    5
 [2,]    2    1    2    3    4    5
 [3,]    3    1    2    3    4    5
 [4,]    4    1    2    3    4    5
 [5,]    5    1    2    3    4    5
 [6,]    6    1    2    3    4    5
 [7,]    7    1    2    3    4    5
 [8,]    8    1    2    3    4    5
 [9,]    9    1    2    3    4    5
[10,]   10    1    2    3    4    5

The best way to login to a guest Linux VirtualBox VM is port forwarding. By default, you should have one interface already which is using NAT. Then go to the Network settings and click the Port Forwarding button. Add a new Rule. As the rule name, insert "ssh". As "Host port", insert 3022. As "Guest port", insert 22. Everything else of the rule can be left blank.

or from the command line

VBoxManage modifyvm myserver --natpf1 "ssh,tcp,,3022,,22"

where 'myserver' is the name of the created VM. Check the added rules:

VBoxManage showvminfo myserver | grep 'Rule'

That's all! Please be sure you don't forget to install an SSH server in the VM:

sudo apt-get install openssh-server

To SSH into the guest VM, write:

ssh -p 3022 [email protected]

Where user is your username within the VM.

WeekMonth = CASE WHEN (DATEPART(day,TestDate) - datepart(dw,TestDate))>= 22 THEN '5' 
                 WHEN (DATEPART(day,TestDate) - datepart(dw,TestDate))>= 15 THEN '4' 
                 WHEN (DATEPART(day,TestDate) - datepart(dw,TestDate))>= 8 THEN '3'
                 WHEN (DATEPART(day,TestDate) - datepart(dw,TestDate))>= 1 THEN '2' 
                 ELSE '1'
             END 

With Underscore.js, you could do

_.find( {"one": [1,2,3], "two": [4,5,6]} )

It will return [1,2,3]

I have used the following lines to display the soft keyboard manually inside the onclick event.

public void showKeyboard(final EmojiconEditText ettext){
          ettext.requestFocus();
          ettext.postDelayed(new Runnable(){
            @Override public void run(){
              InputMethodManager keyboard=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
              keyboard.showSoftInput(ettext,0);
            }
          }
        ,200);
        }

Just get the position of the last character occurrence.

for(String serverId : serverIds) {
 sb.append(serverId);
 sb.append(",");
}
sb.deleteCharAt(sb.lastIndexOf(","));

Since lastIndexOf will perform a reverse search, and you know that it will find at the first try, performance won't be an issue here.

EDIT

Since I keep getting ups on my answer (thanks folks ), it is worth regarding that:

On Java 8 onward it would just be more legible and explicit to use StringJoiner. It has one method for a simple separator, and an overload for prefix and suffix.

Examples taken from here: example

Example using simple separator:

    StringJoiner mystring = new StringJoiner("-");    

    // Joining multiple strings by using add() method  
    mystring.add("Logan");  
    mystring.add("Magneto");  
    mystring.add("Rogue");  
    mystring.add("Storm");  

    System.out.println(mystring);

Output:

Logan-Magneto-Rogue-Storm

Example with suffix and prefix:

    StringJoiner mystring = new StringJoiner(",", "(", ")");    

    // Joining multiple strings by using add() method  
    mystring.add("Negan");  
    mystring.add("Rick");  
    mystring.add("Maggie");  
    mystring.add("Daryl");  

    System.out.println(mystring);

Output

(Negan,Rick,Maggie,Daryl)

You Can create a Linear layout containing an array of TextView (mDots). To represent the textView as Dots provide this HTML source in your code . refer my code . I got this information from Youtube Channel TVAC Studio . here the code : `

    addDotsIndicator(0);
    viewPager.addOnPageChangeListener(viewListener);
}

public void addDotsIndicator(int position)
{
        mDots = new TextView[5];
        mDotLayout.removeAllViews();

        for (int i = 0; i<mDots.length ; i++)
        {
             mDots[i]=new TextView(this);
             mDots[i].setText(Html.fromHtml("&#8226;"));            //HTML for dots
             mDots[i].setTextSize(35);
             mDots[i].setTextColor(getResources().getColor(R.color.colorAccent));

             mDotLayout.addView(mDots[i]);
        }

        if(mDots.length>0)
        {
            mDots[position].setTextColor(getResources().getColor(R.color.orange));
        }
}

ViewPager.OnPageChangeListener viewListener = new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int position, float positionOffset, int 
   positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {

        addDotsIndicator(position);
    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
};`

map rockets and add 10 to its launches:

var rockets = [_x000D_
    { country:'Russia', launches:32 },_x000D_
    { country:'US', launches:23 },_x000D_
    { country:'China', launches:16 },_x000D_
    { country:'Europe(ESA)', launches:7 },_x000D_
    { country:'India', launches:4 },_x000D_
    { country:'Japan', launches:3 }_x000D_
];_x000D_
rockets.map((itm) => {_x000D_
    itm.launches += 10_x000D_
    return itm_x000D_
})_x000D_
console.log(rockets)

If you don't want to modify rockets you can do:

var plusTen = []
rockets.forEach((itm) => {
    plusTen.push({'country': itm.country, 'launches': itm.launches + 10})
})

With Swift 5 and iOS 12.3, according to your needs, you may choose one of the 3 following ways in order to solve your problem.

#1. Using UIView's animate(withDuration:animations:) class method

animate(withDuration:animations:) has the following declaration:

Animate changes to one or more views using the specified duration.

Tabulator is a set of unix command line tools to work with csv files that have header lines. Here is an example to extract columns by name from a file test.csv:

name,sex,house_nr,height,shoe_size
arthur,m,42,181,11.5
berta,f,101,163,8.5
chris,m,1333,175,10
don,m,77,185,12.5
elisa,f,204,166,7

Then tblmap -k name,height test.csv produces

name,height
arthur,181
berta,163
chris,175
don,185
elisa,166

You should look at the article C++ Programming/Type Casting.

It contains a good description of all of the different cast types. The following taken from the above link:

const_cast

const_cast(expression) The const_cast<>() is used to add/remove const(ness) (or volatile-ness) of a variable.

static_cast

static_cast(expression) The static_cast<>() is used to cast between the integer types. 'e.g.' char->long, int->short etc.

Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type.

dynamic_cast

Dynamic cast is used to convert pointers and references at run-time, generally for the purpose of casting a pointer or reference up or down an inheritance chain (inheritance hierarchy).

dynamic_cast(expression)

The target type must be a pointer or reference type, and the expression must evaluate to a pointer or reference. Dynamic cast works only when the type of object to which the expression refers is compatible with the target type and the base class has at least one virtual member function. If not, and the type of expression being cast is a pointer, NULL is returned, if a dynamic cast on a reference fails, a bad_cast exception is thrown. When it doesn't fail, dynamic cast returns a pointer or reference of the target type to the object to which expression referred.

reinterpret_cast

Reinterpret cast simply casts one type bitwise to another. Any pointer or integral type can be casted to any other with reinterpret cast, easily allowing for misuse. For instance, with reinterpret cast one might, unsafely, cast an integer pointer to a string pointer.

Python lists are heterogeneous that is the elements in the same list can be any type of object. The expression: c.append(c) appends the object c what ever it may be to the list. In the case it makes the list itself a member of the list.

The expression c += c adds two lists together and assigns the result to the variable c. The overloaded + operator is defined on lists to create a new list whose contents are the elements in the first list and the elements in the second list.

So these are really just different expressions used to do different things by design.

This should do the trick for you: put include tag inside of a block section.

page1.html:

{% extends "base1.html" %}

{% block foo %}
   {% include "commondata.html" %}
{% endblock %}

page2.html:

{% extends "base2.html" %}

{% block bar %}
   {% include "commondata.html" %}
{% endblock %}

PROBLEM SOLVED

I had exactly the same error. When the remote object got binded to the rmiregistry it was attached with the loopback IP Address which will obviously fail if you try to invoke a method from a remote address. In order to fix this we need to set the java.rmi.server.hostname property to the IP address where other devices can reach your rmiregistry over the network. It doesn't work when you try to set the parameter through the JVM. It worked for me just by adding the following line to my code just before binding the object to the rmiregistry:

System.setProperty("java.rmi.server.hostname","192.168.1.2");

In this case the IP address on the local network of the PC binding the remote object on the RMI Registry is 192.168.1.2.

In my case. I think the problem is in the standard node executable. node target.ts

I replaced it with nodemon and surprisingly it worked!

The way using the standard executable (runner):

node target.ts

The way using the nodemon executable (runner):

nodemon target.ts

Do not forget to install nodemon with npm install nodemon ;P

NOTE: this works amazing for development. But, for runtime, you may execute node with the compiled js file!

If you're using C# 7, you can use a handy wrapper method like this...

public static class TaskEx
{
    public static async Task<(T1, T2)> WhenAll<T1, T2>(Task<T1> task1, Task<T2> task2)
    {
        return (await task1, await task2);
    }
}

...to enable convenient syntax like this when you want to wait on multiple tasks with different return types. You'd have to make multiple overloads for different numbers of tasks to await, of course.

var (someInt, someString) = await TaskEx.WhenAll(GetIntAsync(), GetStringAsync());

However, see Marc Gravell's answer for some optimizations around ValueTask and already-completed tasks if you intend to turn this example into something real.

If you're trying to create a single jar that contains your application and its required libraries, there are two ways (that I know of) to do that. The first is One-Jar, which uses a special classloader to allow the nesting of jars. The second is UberJar, (or Shade), which explodes the included libraries and puts all the classes in the top-level jar.

I should also mention that UberJar and Shade are plugins for Maven1 and Maven2 respectively. As mentioned below, you can also use the assembly plugin (which in reality is much more powerful, but much harder to properly configure).

I'd recommend using a CLR user defined function, if you already know how to program in C#, then the code would be;

using System.Data.SqlTypes;
using System.Net;

public partial class UserDefinedFunctions
{
 [Microsoft.SqlServer.Server.SqlFunction]
 public static SqlString http(SqlString url)
 {
  var wc = new WebClient();
  var html = wc.DownloadString(url.Value);
  return new SqlString (html);
 }
}

And here's installation instructions; https://blog.dotnetframework.org/2019/09/17/make-a-http-request-from-sqlserver-using-a-clr-udf/

Just try this code this code work with me

var posOptions = {timeout: 10000, enableHighAccuracy: false};
$cordovaGeolocation.getCurrentPosition(posOptions).then(function (position) {
var lat = position.coords.latitude;
var long = position.coords.longitude;
 //console.log(lat +"          "+long);
$http.get('https://maps.googleapis.com/maps/api/geocode/json?latlng=' + lat + ',' + long + '&key=your key here').success(function (output) {
//console.log( JSON.stringify(output.results[0]));
//console.log( JSON.stringify(output.results[0].address_components[4].short_name));
var results = output.results;
if (results[0]) {
//console.log("results.length= "+results.length);
//console.log("hi "+JSON.stringify(results[0],null,4));
for (var j = 0; j < results.length; j++){
 //console.log("j= "+j);
//console.log(JSON.stringify(results[j],null,4));
for (var i = 0; i < results[j].address_components.length; i++){
 if(results[j].address_components[i].types[0] == "country") {
 //this is the object you are looking for
  country = results[j].address_components[i];
 }
 }
 }
 console.log(country.long_name);
 console.log(country.short_name);
 } else {
 alert("No results found");
 console.log("No results found");

I think you're getting confused about what can hold what in JSON.Net.

• A JToken is a generic representation of a JSON value of any kind. It could be a string, object, array, property, etc.
• A JProperty is a single JToken value paired with a name. It can only be added to a JObject, and its value cannot be another JProperty.
• A JObject is a collection of JProperties. It cannot hold any other kind of JToken directly.

In your code, you are attempting to add a JObject (the one containing the "banana" data) to a JProperty ("orange") which already has a value (a JObject containing {"colour":"orange","size":"large"}). As you saw, this will result in an error.

What you really want to do is add a JProperty called "banana" to the JObject which contains the other fruit JProperties. Here is the revised code:

JObject foodJsonObj = JObject.Parse(jsonText);
JObject fruits = foodJsonObj["food"]["fruit"] as JObject;
fruits.Add("banana", JObject.Parse(@"{""colour"":""yellow"",""size"":""medium""}"));

In general, this is probably not a great idea, since your html file should only be loading JS files that they actually make use of. Regardless, this would be trivial to do with any server-side scripting language. Just insert the script tags before serving the pages to the client.

If you want to do it without using server-side scripting, you could drop your JS files into a directory that allows listing the directory contents, and then use XMLHttpRequest to read the contents of the directory, and parse out the file names and load them.

Option #3 is to have a "loader" JS file that uses getScript() to load all of the other files. Put that in a script tag in all of your html files, and then you just need to update the loader file whenever you upload a new script.

It looks to me as though the basic problem is that you have one wait() call rather than a loop that waits until there are no more children. You also only wait if the last fork() is successful rather than if at least one fork() is successful.

You should only use _exit() if you don't want normal cleanup operations - such as flushing open file streams including stdout. There are occasions to use _exit(); this is not one of them. (In this example, you could also, of course, simply have the children return instead of calling exit() directly because returning from main() is equivalent to exiting with the returned status. However, most often you would be doing the forking and so on in a function other than main(), and then exit() is often appropriate.)

Hacked, simplified version of your code that gives the diagnostics I'd want. Note that your for loop skipped the first element of the array (mine doesn't).

#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <sys/wait.h>

int main(void)
{
    pid_t child_pid, wpid;
    int status = 0;
    int i;
    int a[3] = {1, 2, 1};

    printf("parent_pid = %d\n", getpid());
    for (i = 0; i < 3; i++)
    {
        printf("i = %d\n", i);
        if ((child_pid = fork()) == 0)
        {
            printf("In child process (pid = %d)\n", getpid());
            if (a[i] < 2)
            {
                printf("Should be accept\n");
                exit(1);
            }
            else
            {
                printf("Should be reject\n");
                exit(0);
            }
            /*NOTREACHED*/
        }
    }

    while ((wpid = wait(&status)) > 0)
    {
        printf("Exit status of %d was %d (%s)\n", (int)wpid, status,
               (status > 0) ? "accept" : "reject");
    }
    return 0;
}

Example output (MacOS X 10.6.3):

parent_pid = 15820
i = 0
i = 1
In child process (pid = 15821)
Should be accept
i = 2
In child process (pid = 15822)
Should be reject
In child process (pid = 15823)
Should be accept
Exit status of 15823 was 256 (accept)
Exit status of 15822 was 0 (reject)
Exit status of 15821 was 256 (accept)

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

e.g.

 ColorTranslator.ToHtml(Color.FromArgb(Color.Tomato.ToArgb()))

This can avoid the KnownColor trick.

Apache mod_rewrite

What you're looking for is mod_rewrite,

Description: Provides a rule-based rewriting engine to rewrite requested URLs on the fly.

Generally speaking, mod_rewrite works by matching the requested document against specified regular expressions, then performs URL rewrites internally (within the apache process) or externally (in the clients browser). These rewrites can be as simple as internally translating example.com/foo into a request for example.com/foo/bar.

The Apache docs include a mod_rewrite guide and I think some of the things you want to do are covered in it. Detailed mod_rewrite guide.

Force the www subdomain

I would like it to force "www" before every url, so its not domain.com but www.domain.com/page

The rewrite guide includes instructions for this under the Canonical Hostname example.

Remove trailing slashes (Part 1)

I would like to remove all trailing slashes from pages

I'm not sure why you would want to do this as the rewrite guide includes an example for the exact opposite, i.e., always including a trailing slash. The docs suggest that removing the trailing slash has great potential for causing issues:

Trailing Slash Problem

Description:

Every webmaster can sing a song about the problem of the trailing slash on URLs referencing directories. If they are missing, the server dumps an error, because if you say /~quux/foo instead of /~quux/foo/ then the server searches for a file named foo. And because this file is a directory it complains. Actually it tries to fix it itself in most of the cases, but sometimes this mechanism need to be emulated by you. For instance after you have done a lot of complicated URL rewritings to CGI scripts etc.

Perhaps you could expand on why you want to remove the trailing slash all the time?

Remove .php extension

I need it to remove the .php

The closest thing to doing this that I can think of is to internally rewrite every request document with a .php extension, i.e., example.com/somepage is instead processed as a request for example.com/somepage.php. Note that proceeding in this manner would would require that each somepage actually exists as somepage.php on the filesystem.

With the right combination of regular expressions this should be possible to some extent. However, I can foresee some possible issues with index pages not being requested correctly and not matching directories correctly.

For example, this will correctly rewrite example.com/test as a request for example.com/test.php:

RewriteEngine  on
RewriteRule ^(.*)$ $1.php

But will make example.com fail to load because there is no example.com/.php

I'm going to guess that if you're removing all trailing slashes, then picking a request for a directory index from a request for a filename in the parent directory will become almost impossible. How do you determine a request for the directory 'foobar':

example.com/foobar

from a request for a file called foobar (which is actually foobar.php)

example.com/foobar

It might be possible if you used the RewriteBase directive. But if you do that then this problem gets way more complicated as you're going to require RewriteCond directives to do filesystem level checking if the request maps to a directory or a file.

That said, if you remove your requirement of removing all trailing slashes and instead force-add trailing slashes the "no .php extension" problem becomes a bit more reasonable.

# Turn on the rewrite engine
RewriteEngine  on
# If the request doesn't end in .php (Case insensitive) continue processing rules
RewriteCond %{REQUEST_URI} !\.php$ [NC]
# If the request doesn't end in a slash continue processing the rules
RewriteCond %{REQUEST_URI} [^/]$
# Rewrite the request with a .php extension. L means this is the 'Last' rule
RewriteRule ^(.*)$ $1.php [L]

This still isn't perfect -- every request for a file still has .php appended to the request internally. A request for 'hi.txt' will put this in your error logs:

[Tue Oct 26 18:12:52 2010] [error] [client 71.61.190.56] script '/var/www/test.peopleareducks.com/rewrite/hi.txt.php' not found or unable to stat

But there is another option, set the DefaultType and DirectoryIndex directives like this:

DefaultType application/x-httpd-php
DirectoryIndex index.php index.html

Update 2013-11-14 - Fixed the above snippet to incorporate nicorellius's observation

Now requests for hi.txt (and anything else) are successful, requests to example.com/test will return the processed version of test.php, and index.php files will work again.

I must give credit where credit is due for this solution as I found it Michael J. Radwins Blog by searching Google for php no extension apache.

Remove trailing slashes

Some searching for apache remove trailing slashes brought me to some Search Engine Optimization pages. Apparently some Content Management Systems (Drupal in this case) will make content available with and without a trailing slash in URls, which in the SEO world will cause your site to incur a duplicate content penalty. Source

The solution seems fairly trivial, using mod_rewrite we rewrite on the condition that the requested resource ends in a / and rewrite the URL by sending back the 301 Permanent Redirect HTTP header.

Here's his example which assumes your domain is blamcast.net and allows the the request to optionally be prefixed with www..

#get rid of trailing slashes
RewriteCond %{HTTP_HOST} ^(www.)?blamcast\.net$ [NC]
RewriteRule ^(.+)/$ http://%{HTTP_HOST}/$1 [R=301,L]

Now we're getting somewhere. Lets put it all together and see what it looks like.

Mandatory www., no .php, and no trailing slashes

This assumes the domain is foobar.com and it is running on the standard port 80.

# Process all files as PHP by default
DefaultType application/x-httpd-php
# Fix sub-directory requests by allowing 'index' as a DirectoryIndex value
DirectoryIndex index index.html

# Force the domain to load with the www subdomain prefix
# If the request doesn't start with www...
RewriteCond %{HTTP_HOST}   !^www\.foobar\.com [NC]
# And the site name isn't empty
RewriteCond %{HTTP_HOST}   !^$
# Finally rewrite the request: end of rules, don't escape the output, and force a 301 redirect
RewriteRule ^/?(.*)         http://www.foobar.com/$1 [L,R,NE]

#get rid of trailing slashes
RewriteCond %{HTTP_HOST} ^(www.)?foobar\.com$ [NC]
RewriteRule ^(.+)/$ http://%{HTTP_HOST}/$1 [R=301,L]

The 'R' flag is described in the RewriteRule directive section. Snippet:

redirect|R [=code] (force redirect) Prefix Substitution with http://thishost[:thisport]/ (which makes the new URL a URI) to force a external redirection. If no code is given, a HTTP response of 302 (MOVED TEMPORARILY) will be returned.

Final Note

I wasn't able to get the slash removal to work successfully. The redirect ended up giving me infinite redirect loops. After reading the original solution closer I get the impression that the example above works for them because of how their Drupal installation is configured. He mentions specifically:

On a normal Drupal site, with clean URLs enabled, these two addresses are basically interchangeable

In reference to URLs ending with and without a slash. Furthermore,

Drupal uses a file called .htaccess to tell your web server how to handle URLs. This is the same file that enables Drupal's clean URL magic. By adding a simple redirect command to the beginning of your .htaccess file, you can force the server to automatically remove any trailing slashes.

Please add this option:

//Boolean - Whether the scale should start at zero, or an order of magnitude down from the lowest value
scaleBeginAtZero : true,

(Reference: Chart.js)

N.B: The original solution I posted was for Highcharts, if you are not using Highcharts then please remove the tag to avoid confusion

The difference between do while (exit check) and while (entry check) is that while entering in do while it will not check but in while it will first check

The example is as such:

Program 1:

int a=10;
do{
System.out.println(a);
}
while(a<10);

//here the a is not less than 10 then also it will execute once as it will execute do while exiting it checks that a is not less than 10 so it will exit the loop

Program 2:

int b=0;
while(b<10)
{
System.out.println(b);
}
//here nothing will be printed as the value of b is not less than 10 and it will not let enter the loop and will exit

output Program 1:

10

output Program 2:

[nothing is printed]

note:

output of the program 1 and program 2 will be same if we assign a=0 and b=0 and also put a++; and b++; in the respective body of the program.

I tried all of the listed answers and none of them was useful. The problem was due to existence of an another plist file linked from a submodule via cocoapods. Luckily this was my own module, so I just deleted this plist from the submodule project and reinstalled pods.

solution

Later on I understood that the key of the problem was in the name of that second plist: simply info.plist. You may rename the file and relink it via a sources section of a submodule

That second plist file had a unique name, so Xcode was not supposed to become frustrated. Even my target settings pointed on a main plist, not on a info.plist. Looks like Xcode takes special consideraions about that name

The bug reproduced in Xcode 6.4 and Xcode 7.0

Just use strcmp() for case sensitive and strcmpi() or stricmp() for case insensitive comparison. Which are both in the header file <string.h>

format:

int strcmp(const char*,const char*);    //for case sensitive
int strcmpi(const char*,const char*);   //for case insensitive

Usage:

string a="apple",b="ApPlE",c="ball";
if(strcmpi(a.c_str(),b.c_str())==0)      //(if it is a match it will return 0)
    cout<<a<<" and "<<b<<" are the same"<<"\n";
if(strcmpi(a.c_str(),b.c_str()<0)
    cout<<a[0]<<" comes before ball "<<b[0]<<", so "<<a<<" comes before "<<b;

Output

apple and ApPlE are the same

a comes before b, so apple comes before ball

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

These utilities include null-safe or null-tolerant methods

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

I am trying to compare date which are in string format like '20110930'

benchMark = datetime.datetime.strptime('20110701', "%Y%m%d") 

actualDate = datetime.datetime.strptime('20110930', "%Y%m%d")

if actualDate.date() < benchMark.date():
    print True

As Paddy mentioned: if you use an overload of UrlHelper.Action() that explicitly specifies the protocol to use, the generated URL will be absolute and fully qualified instead of being relative.

I wrote a blog post called How to build absolute action URLs using the UrlHelper class in which I suggest to write a custom extension method for the sake of readability:

/// <summary>
/// Generates a fully qualified URL to an action method by using
/// the specified action name, controller name and route values.
/// </summary>
/// <param name="url">The URL helper.</param>
/// <param name="actionName">The name of the action method.</param>
/// <param name="controllerName">The name of the controller.</param>
/// <param name="routeValues">The route values.</param>
/// <returns>The absolute URL.</returns>
public static string AbsoluteAction(this UrlHelper url,
    string actionName, string controllerName, object routeValues = null)
{
    string scheme = url.RequestContext.HttpContext.Request.Url.Scheme;

    return url.Action(actionName, controllerName, routeValues, scheme);
}

You can then simply use it like that in your view:

@Url.AbsoluteAction("Action", "Controller")

Arrow looks promising for this:

>>> import arrow
>>> arrow.get('2014-11-13T14:53:18.694072+00:00').datetime
datetime.datetime(2014, 11, 13, 14, 53, 18, 694072, tzinfo=tzoffset(None, 0))

Arrow is a Python library that provides a sensible, intelligent way of creating, manipulating, formatting and converting dates and times. Arrow is simple, lightweight and heavily inspired by moment.js and requests.

A Queue is an interface, which means you cannot construct a Queue directly.

The best option is to construct off a class that already implements the Queue interface, like one of the following: AbstractQueue, ArrayBlockingQueue, ArrayDeque, ConcurrentLinkedQueue, DelayQueue, LinkedBlockingQueue, LinkedList, PriorityBlockingQueue, PriorityQueue, or SynchronousQueue.

An alternative is to write your own class which implements the necessary Queue interface. It is not needed except in those rare cases where you wish to do something special while providing the rest of your program with a Queue.

public class MyQueue<T extends Tree> implements Queue<T> {
   public T element() {
     ... your code to return an element goes here ...
   }

   public boolean offer(T element) {
     ... your code to accept a submission offer goes here ...
   }

   ... etc ...
}

An even less used alternative is to construct an anonymous class that implements Queue. You probably don't want to do this, but it's listed as an option for the sake of covering all the bases.

new Queue<Tree>() {
   public Tree element() {
     ...
   };

   public boolean offer(Tree element) {
     ...
   };
   ...
};

This should work:

Process.Start(@"<directory goes here>")

Or if you'd like a method to run programs/open files and/or folders:

private void StartProcess(string path)
{
    ProcessStartInfo StartInformation = new ProcessStartInfo();

    StartInformation.FileName = path;

    Process process = Process.Start(StartInformation);

    process.EnableRaisingEvents = true;
}

And then call the method and in the parenthesis put either the directory of the file and/or folder there or the name of the application. Hope this helped!

I experienced this while working with nested RelativeLayouts. My solution ended up being simple, but it's a little gotcha that's worth being aware of.

My layout was defined with...

android:layout_height="fill_parent"
android:layout_below="@id/someLayout
android:gravity="center"

...however, I didn't think that the layout below this one was placed on top of it. Everything inside this layout was shifted towards the bottom instead of centered. Adding...

android:layout_above="@id/bottomLayout"

...fixed my issue.

In the module build.gradle, in the task field, I get an error unless I use:

def ndkDir = plugins.getPlugin('com.android.application').sdkHandler.getNdkFolder()

I see people using

def ndkDir = android.plugin.ndkFolder

and

def ndkDir = plugins.getPlugin('com.android.library').sdkHandler.getNdkFolder()

but neither of those worked until I changed it to the plugin I was actually importing.

@Rogach

and you may like to add:

// to remote the spacing between the image and button's borders
button.setMargin(new Insets(0, 0, 0, 0));
// to add a different background
button.setBackground( ... );
// to remove the border
button.setBorder(null);

Compare the two dates:

  Date today = new Date();                   
  Date myDate = new Date(today.getYear(),today.getMonth()-1,today.getDay());
  System.out.println("My Date is"+myDate);    
  System.out.println("Today Date is"+today);
  if (today.compareTo(myDate)<0)
      System.out.println("Today Date is Lesser than my Date");
  else if (today.compareTo(myDate)>0)
      System.out.println("Today Date is Greater than my date"); 
  else
      System.out.println("Both Dates are equal"); 

Your List has no items, that's why access to non-existing 0th item

myList[0] == null

throws Index was out of range exception; when you want to access n-th item check

  if (myList.Count > n)
    DoSomething(myList[n])

in your case

  if (myList.Count > 0) // <- You can safely get 0-th item
    if (myList[0] == null) 
      myList.Add("new item");

Up to Postgres 11 generated columns are not supported - as defined in the SQL standard and implemented by some RDBMS including DB2, MySQL and Oracle. Nor the similar "computed columns" of SQL Server.

STORED generated columns are introduced with Postgres 12. Trivial example:

CREATE TABLE tbl (
  int1    int
, int2    int
, product bigint GENERATED ALWAYS AS (int1 * int2) STORED
);

db<>fiddle here

VIRTUAL generated columns may come with one of the next iterations. (Not in Postgres 13, yet) .

Related:

• Attribute notation for function call gives error

Until then, you can emulate VIRTUAL generated columns with a function using attribute notation (tbl.col) that looks and works much like a virtual generated column. That's a bit of a syntax oddity which exists in Postgres for historic reasons and happens to fit the case. This related answer has code examples:

• Store common query as column?

The expression (looking like a column) is not included in a SELECT * FROM tbl, though. You always have to list it explicitly.

Can also be supported with a matching expression index - provided the function is IMMUTABLE. Like:

CREATE FUNCTION col(tbl) ... AS ...  -- your computed expression here
CREATE INDEX ON tbl(col(tbl));

Alternatives

Alternatively, you can implement similar functionality with a VIEW, optionally coupled with expression indexes. Then SELECT * can include the generated column.

"Persisted" (STORED) computed columns can be implemented with triggers in a functionally identical way.

Materialized views are a closely related concept, implemented since Postgres 9.3.
In earlier versions one can manage MVs manually.

{
   echo 'Something';
}

ConcurrentHashMap is preferred when you can use it - though it requires at least Java 5.

It is designed to scale well when used by multiple threads. Performance may be marginally poorer when only a single thread accesses the Map at a time, but significantly better when multiple threads access the map concurrently.

I found a blog entry that reproduces a table from the excellent book Java Concurrency In Practice, which I thoroughly recommend.

Collections.synchronizedMap makes sense really only if you need to wrap up a map with some other characteristics, perhaps some sort of ordered map, like a TreeMap.

Add this style to your span:

position:relative; 
top: 10px;

Demo: http://jsfiddle.net/BqTUS/3/

The solution from Artyom Neustroev does not work on complex objects, so here is a working solution based on his idea:

function propertiesToArray(obj) {
    const isObject = val =>
        typeof val === 'object' && !Array.isArray(val);

    const addDelimiter = (a, b) =>
        a ? `${a}.${b}` : b;

    const paths = (obj = {}, head = '') => {
        return Object.entries(obj)
            .reduce((product, [key, value]) => 
                {
                    let fullPath = addDelimiter(head, key)
                    return isObject(value) ?
                        product.concat(paths(value, fullPath))
                    : product.concat(fullPath)
                }, []);
    }

    return paths(obj);
}

Expanding on the accepted answer:

function mysql_query_or_die($query) {
    $result = mysql_query($query);
    if ($result)
        return $result;
    else {
        $err = mysql_error();
        die("<br>{$query}<br>*** {$err} ***<br>");
    }
}

...
$query = "SELECT * FROM my_table";
$result = mysql_query_or_die($query);
echo("<table>");
$first_row = true;
while ($row = mysql_fetch_assoc($result)) {
    if ($first_row) {
        $first_row = false;
        // Output header row from keys.
        echo '<tr>';
        foreach($row as $key => $field) {
            echo '<th>' . htmlspecialchars($key) . '</th>';
        }
        echo '</tr>';
    }
    echo '<tr>';
    foreach($row as $key => $field) {
        echo '<td>' . htmlspecialchars($field) . '</td>';
    }
    echo '</tr>';
}
echo("</table>");

Benefits:

• Using mysql_fetch_assoc (instead of mysql_fetch_array with no 2nd parameter to specify type), we avoid getting each field twice, once for a numeric index (0, 1, 2, ..), and a second time for the associative key.

• Shows field names as a header row of table.

• Shows how to get both column name ($key) and value ($field) for each field, as iterate over the fields of a row.

• Wrapped in <table> so displays properly.

• (OPTIONAL) dies with display of query string and mysql_error, if query fails.

Example Output:

Id      Name
777     Aardvark
50      Lion
9999    Zebra

my rule of thumb is:

rebase for branches with the same name, merge otherwise.

examples for same names would be master, origin/master and otherRemote/master.

if develop exists only in the local repository, and it is always based on a recent origin/master commit, you should call it master, and work there directly. it simplifies your life, and presents things as they actually are: you are directly developing on the master branch.

if develop is shared, it should not be rebased on master, just merged back into it with --no-ff. you are developing on develop. master and develop have different names, because we want them to be different things, and stay separate. do not make them same with rebase.

According to a slideshow about Facebook's Messaging system, Facebook uses the comet technology to "push" message to web browsers. Facebook's comet server is built on the open sourced Erlang web server mochiweb.

In the picture below, the phrase "channel clusters" means "comet servers".

Many other big web sites build their own comet server, because there are differences between every company's need. But build your own comet server on a open source comet server is a good approach.

You can try icomet, a C1000K C++ comet server built with libevent. icomet also provides a JavaScript library, it is easy to use as simple as:

var comet = new iComet({
    sign_url: 'http://' + app_host + '/sign?obj=' + obj,
    sub_url: 'http://' + icomet_host + '/sub',
    callback: function(msg){
        // on server push
        alert(msg.content);
    }
});

icomet supports a wide range of Browsers and OSes, including Safari(iOS, Mac), IEs(Windows), Firefox, Chrome, etc.

Assuming you have GNU find:

find . -size +10000k -printf '%s %f\n'

If you want a constant width for the size field, you can do something like:

find . -size +10000k -printf '%10s %f\n'

Note that -size +1000k selects files of at least 10,240,000 bytes (k is 1024, not 1000). You said in a comment that you want files bigger than 1M; if that's 1024*1024 bytes, then this:

find . -size +1M ...

will do the trick -- except that it will also print the size and name of files that are exactly 1024*1024 bytes. If that matters, you could use:

find . -size +1048575c ...

You need to decide just what criterion you want.

Move points into test:

def test():
    points = 0
    addpoint = raw_input ("type ""add"" to add a point")
    ...

or use global statement, but it is bad practice. But better way it move points to parameters:

def test(points=0):
    addpoint = raw_input ("type ""add"" to add a point")
    ...

if val is not None:
    print(val)
else:
    pass

check wheather particular data is not empty or null.

I am using macOS catalina ,

      npm init 

I got error

       operation not permitted, uv_cwd

in 2021, this is how you can fix this problem.

very simple:

step 1: go to parent folder

         cd ../
         

step 2: go to your project folder again,

         cd  your-project-folder

That is it. it works.

REDUX

You can also use react-router-redux which has goBack() and push().

Here is a sampler pack for that:

In your app's entry point, you need ConnectedRouter, and a sometimes tricky connection to hook up is the history object. The Redux middleware listens to history changes:

import React from 'react'
import { render } from 'react-dom'
import { ApolloProvider } from 'react-apollo'
import { Provider } from 'react-redux'
import { ConnectedRouter } from 'react-router-redux'
import client from './components/apolloClient'
import store, { history } from './store'
import Routes from './Routes'
import './index.css'

render(
  <ApolloProvider client={client}>
    <Provider store={store}>
      <ConnectedRouter history={history}>
        <Routes />
      </ConnectedRouter>
    </Provider>
  </ApolloProvider>,
  document.getElementById('root'),
)

I will show you a way to hook up the history. Notice how the history is imported into the store and also exported as a singleton so it can be used in the app's entry point:

import { createStore, applyMiddleware, compose } from 'redux'
import { routerMiddleware } from 'react-router-redux'
import thunk from 'redux-thunk'
import createHistory from 'history/createBrowserHistory'
import rootReducer from './reducers'

export const history = createHistory()

const initialState = {}
const enhancers = []
const middleware = [thunk, routerMiddleware(history)]

if (process.env.NODE_ENV === 'development') {
  const { devToolsExtension } = window
  if (typeof devToolsExtension === 'function') {
    enhancers.push(devToolsExtension())
  }
}

const composedEnhancers = compose(applyMiddleware(...middleware), ...enhancers)
const store = createStore(rootReducer, initialState, composedEnhancers)

export default store

The above example block shows how to load the react-router-redux middleware helpers which complete the setup process.

I think this next part is completely extra, but I will include it just in case someone in the future finds benefit:

import { combineReducers } from 'redux'
import { routerReducer as routing } from 'react-router-redux'

export default combineReducers({
  routing, form,
})

I use routerReducer all the time because it allows me to force reload Components that normally do not due to shouldComponentUpdate. The obvious example is when you have a Nav Bar that is supposed to update when a user presses a NavLink button. If you go down that road, you will learn that Redux's connect method uses shouldComponentUpdate. With routerReducer, you can use mapStateToProps to map routing changes into the Nav Bar, and this will trigger it to update when the history object changes.

Like this:

const mapStateToProps = ({ routing }) => ({ routing })

export default connect(mapStateToProps)(Nav)

Forgive me while I add some extra keywords for people: if your component isn't updating properly, investigate shouldComponentUpdate by removing the connect function and see if it fixes the problem. If so, pull in the routerReducer and the component will update properly when the URL changes.

In closing, after doing all that, you can call goBack() or push() anytime you want!

Try it now in some random component:

1. Import in connect()
2. You don't even need mapStateToProps or mapDispatchToProps
3. Import in goBack and push from react-router-redux
4. Call this.props.dispatch(goBack())
5. Call this.props.dispatch(push('/sandwich'))
6. Experience positive emotion

If you need more sampling, check out: https://www.npmjs.com/package/react-router-redux

You could check whether the value of your selectOneMenu component belongs to the list of subjects.

Namely:

public void subjectSelectionChanged() {
    // Cancel if subject is manually written
    if (!subjectList.contains(aktNachricht.subject)) { return; }
    // Write your code here in case the user selected (or wrote) an item of the list
    // ....
}

Supposedly subjectList is a collection type, like ArrayList. Of course here your code will run in case the user writes an item of your selectOneMenu list.

If you want to do it in CSS:

#ID { cursor: none !important; }

htons is host-to-network short

This means it works on 16-bit short integers. i.e. 2 bytes.

This function swaps the endianness of a short.

Your number starts out at:

0001 0011 1000 1001 = 5001

When the endianness is changed, it swaps the two bytes:

1000 1001 0001 0011 = 35091

its even easier:

fileList.Where(item => filterList.Contains(item))

in case you want to filter not for an exact match but for a "contains" you can use this expression:

var t = fileList.Where(file => filterList.Any(folder => file.ToUpperInvariant().Contains(folder.ToUpperInvariant())));

Should be something like this:

 function isJson($string)
 {
    // 1. Speed up the checking & prevent exception throw when non string is passed
    if (is_numeric($string) ||
        !is_string($string) ||
        !$string) {
        return false;
    }

    $cleaned_str = trim($string);
    if (!$cleaned_str || !in_array($cleaned_str[0], ['{', '['])) {
        return false;
    }

    // 2. Actual checking
    $str = json_decode($string);
    return (json_last_error() == JSON_ERROR_NONE) && $str && $str != $string;
}

UnitTest

public function testIsJson()
{
    $non_json_values = [
        "12",
        0,
        1,
        12,
        -1,
        '',
        null,
        0.1,
        '.',
        "''",
        true,
        false,
        [],
        '""',
        '[]',
        '   {',
        '   [',
    ];

   $json_values = [
        '{}',
        '{"foo": "bar"}',
        '[{}]',
        '  {}',
        ' {}  '
    ];

   foreach ($non_json_values as $non_json_value) {
        $is_json = isJson($non_json_value);
        $this->assertFalse($is_json);
    }

    foreach ($json_values as $json_value) {
        $is_json = isJson($json_value);
        $this->assertTrue($is_json);
    }
}

In java, every numeric expression like:

anyPrimitive zas = 1;
anyPrimitive bar = 3;
?? x = zas  + bar 

x will always result to be at least an int, or a long if one of the addition elements was a long.

But there's are some quirks tough

byte a = 1; // 1 is an int, but it won't compile if you use a variable
a += 2; // the shortcut works even when 2 is an int
a++; // the post and pre increment operator work

For ssh style urls just add ssh before the url:

yarn add ssh://<whatever>@<xxx>#<branch,tag,commit>

This worked out just fine for me:

git update-index --skip-worktree

If it doesn't work with the pathname, try the filename. Let me know if this worked for you too.

Bye!

I had a similar error..This might be due to two reasons. a) If you have used variables, re-evaluate the expressions in which variables are used and make sure the expression is evaluated without errors. b) If you are deleting the excel sheet and creating excel sheet on the fly in your package.

JavaScript arrays are designed to hold data with numeric indexes. You can add named properties to them because an array is a type of object (and this can be useful when you want to store metadata about an array which holds normal, ordered, numerically indexed data), but that isn't what they are designed for.

The JSON array data type cannot have named keys on an array.

When you pass a JavaScript array to JSON.stringify the named properties will be ignored.

If you want named properties, use an Object, not an Array.

const test = {}; // Object_x000D_
test.a = 'test';_x000D_
test.b = []; // Array_x000D_
test.b.push('item');_x000D_
test.b.push('item2');_x000D_
test.b.push('item3');_x000D_
test.b.item4 = "A value"; // Ignored by JSON.stringify_x000D_
const json = JSON.stringify(test);_x000D_
console.log(json);

A realm can be seen as an area (not a particular page, it could be a group of pages) for which the credentials are used; this is also the string that will be shown when the browser pops up the login window, e.g.

Please enter your username and password for <realm name>:

When the realm changes, the browser may show another popup window if it doesn't have credentials for that particular realm.

Few points

struct Vector y = (struct Vector*)malloc(sizeof(struct Vector)); is wrong

it should be struct Vector *y = (struct Vector*)malloc(sizeof(struct Vector)); since y holds pointer to struct Vector.

1st malloc() only allocates memory enough to hold Vector structure (which is pointer to double + int)

2nd malloc() actually allocate memory to hold 10 double.

"bad enough not having a traditional for(;;) looper"?? What?

Are you trying to do

import string
for c in string.lowercase:
    ...do something with c...

Or perhaps you're using string.uppercase or string.letters?

Python doesn't have for(;;) because there are often better ways to do it. It also doesn't have character math because it's not necessary, either.

use value instead of query (must specify index of node to return in the XQuery as well as passing the sql data type to return as the second parameter):

select
    xt.Id
    , x.m.value( '@id[1]', 'varchar(max)' ) MetricId
from
    XmlTest xt
    cross apply xt.XmlData.nodes( '/Sqm/Metrics/Metric' ) x(m)

Check MediaQuery class

For example, to learn the size of the current media (e.g., the window containing your app), you can read the MediaQueryData.size property from the MediaQueryData returned by MediaQuery.of: MediaQuery.of(context).size.

So you can do the following:

 new Container(
                      height: MediaQuery.of(context).size.height/2,
..            )

Simple solution, make a custom control. (this is made in Xamarin android but should port easily to java)

public class EditTextDecimalNumber:EditText
{
    readonly string _numberFormatDecimalSeparator;

    public EditTextDecimalNumber(Context context, IAttributeSet attrs) : base(context, attrs)
    {
        InputType = InputTypes.NumberFlagDecimal;
        TextChanged += EditTextDecimalNumber_TextChanged;
        _numberFormatDecimalSeparator = System.Threading.Thread.CurrentThread.CurrentUICulture.NumberFormat.NumberDecimalSeparator;

        KeyListener = DigitsKeyListener.GetInstance($"0123456789{_numberFormatDecimalSeparator}");
    }

    private void EditTextDecimalNumber_TextChanged(object sender, TextChangedEventArgs e)
    {
        int noOfOccurence = this.Text.Count(x => x.ToString() == _numberFormatDecimalSeparator);
        if (noOfOccurence >=2)
        {
            int lastIndexOf = this.Text.LastIndexOf(_numberFormatDecimalSeparator,StringComparison.CurrentCulture);
            if (lastIndexOf!=-1)
            {
                this.Text = this.Text.Substring(0, lastIndexOf);
                this.SetSelection(this.Text.Length);
            }

        }
    }
}

autocomplete="off" is usually working, but not always. It depends on the name of the input field. Names like "address", 'email', 'name' - will be autocompleted (browsers think they help users), when fields like "code", "pin" - will not be autocompleted (if autocomplete="off" is set)

My problems was - autocomplete was messing with google address helper

I fixed it by renaming it

from

<input type="text" name="address" autocomplete="off">

to

<input type="text" name="the_address" autocomplete="off">

Tested in chrome 71.

I wanted to add to Joseph Kingry's answer. He provided the solution but at first I couldn't get it to work either and got a result just like Adhip Gupta. And then I realized that the route has to exist in the first place and the parameters need to match the route exactly. So I had an id and then a text parameter for my route which also needed to be included too.

Html.ActionLink(article.Title, "Login", "Item", new { id = article.ArticleID, title = article.Title }, null)

You can use the Directory.GetFiles method

Also see Directory.GetFiles Method (String, String, SearchOption)

You can specify the search option in this overload.

TopDirectoryOnly: Includes only the current directory in a search.

AllDirectories: Includes the current directory and all the subdirectories in a search operation. This option includes reparse points like mounted drives and symbolic links in the search.

// searches the current directory and sub directory
int fCount = Directory.GetFiles(path, "*", SearchOption.AllDirectories).Length;
// searches the current directory
int fCount = Directory.GetFiles(path, "*", SearchOption.TopDirectoryOnly).Length;

For ios6 using autolayout I had to add a little bit of code to remove the constraints too.

NSMutableArray * constraints_to_remove = [ @[] mutableCopy] ;
for( NSLayoutConstraint * constraint in tagview.constraints) {
    if( [tagview.subviews containsObject:constraint.firstItem] ||
       [tagview.subviews containsObject:constraint.secondItem] ) {
        [constraints_to_remove addObject:constraint];
    }
}
[tagview removeConstraints:constraints_to_remove];

[ [tagview subviews] makeObjectsPerformSelector:@selector(removeFromSuperview)];

I'm sure theres a neater way to do this, but it worked for me. In my case I could not use a direct [tagview removeConstraints:tagview.constraints] as there were constraints set in XCode that were getting cleared.

Not always there's a servlet before of an upload (I could use a filter for example). Or could be that the same controller ( again a filter or also a servelt ) can serve many actions, so I think that rely on that servlet configuration to use the getPart method (only for Servlet API >= 3.0), I don't know, I don't like.

In general, I prefer independent solutions, able to live alone, and in this case http://commons.apache.org/proper/commons-fileupload/ is one of that.

List<FileItem> multiparts = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
    for (FileItem item : multiparts) {
        if (!item.isFormField()) {
            //your operations on file
        } else {
            String name = item.getFieldName();
            String value = item.getString();
            //you operations on paramters
        }
}

I am using this solution:

1. Create a separate repository that holds folder node_modules. If you have native modules that should be build for specific platform then create a separate repository for each platform.

2. Attach these repositories to your project repository with git submodule:

   git submodule add .../your_project_node_modules_windows.git node_modules_windows

   git submodule add .../your_project_node_modules_linux_x86_64 node_modules_linux_x86_64

3. Create a link from platform-specific node_modules to node_modules directory and add node_modules to .gitignore.

4. Run npm install.

5. Commit submodule repository changes.

6. Commit your project repository changes.

So you can easily switch between node_modules on different platforms (for example, if you are developing on OS X and deploying to Linux).

This Message is also possible to pop up, if there is a typo in the fields on which you define a join

I was facing the same problem when I included one third party framework.

The issue got resolved when I removed armv7s from the Valid Architectures entry in Build Settings of the target, it starts working.

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

What is a raw type and why do I often hear that they shouldn't be used in new code?

A "raw type" is the use of a generic class without specifying a type argument(s) for its parameterized type(s), e.g. using List instead of List<String>. When generics were introduced into Java, several classes were updated to use generics. Using these class as a "raw type" (without specifying a type argument) allowed legacy code to still compile.

"Raw types" are used for backwards compatibility. Their use in new code is not recommended because using the generic class with a type argument allows for stronger typing, which in turn may improve code understandability and lead to catching potential problems earlier.

What is the alternative if we can't use raw types, and how is it better?

The preferred alternative is to use generic classes as intended - with a suitable type argument (e.g. List<String>). This allows the programmer to specify types more specifically, conveys more meaning to future maintainers about the intended use of a variable or data structure, and it allows compiler to enforce better type-safety. These advantages together may improve code quality and help prevent the introduction of some coding errors.

For example, for a method where the programmer wants to ensure a List variable called 'names' contains only Strings:

List<String> names = new ArrayList<String>();
names.add("John");          // OK
names.add(new Integer(1));  // compile error

Old question, but there's an easier way.

sns.pointplot(x=x_col,y=y_col,data=df_1,color='blue')
sns.pointplot(x=x_col,y=y_col,data=df_2,color='green')
sns.pointplot(x=x_col,y=y_col,data=df_3,color='red')
plt.legend(labels=['legendEntry1', 'legendEntry2', 'legendEntry3'])

This lets you add the plots sequentially, and not have to worry about any of the matplotlib crap besides defining the legend items.

If you're on Windows:

Go to your php.ini file and remove the ; mark from the beginning of the following line:

;extension=php_curl.dll

After you have saved the file you must restart your HTTP server software (e.g. Apache) before this can take effect.

For Ubuntu 13.0 and above, simply use the debundled package. In a terminal type the following to install it and do not forgot to restart server.

sudo apt-get install php-curl

Or if you're using the old PHP5

sudo apt-get install php5-curl

or

sudo apt-get install php5.6-curl

Then restart apache to activate the package with

sudo service apache2 restart

In lieu of changing the port, I reclaimed port 80 as being used by IIS.

So I went to services, and stopped the following:

1. World Wide Web Publishing Services.
2. Web Management Service
3. Web Deployment Agent Service.

set them to manual so that it will not start on dev environment restart.

Here is an example of decoding a generic map using both switch and reflection, so if you don't match the type, use reflection to figure it out and then add the type in next time.

var data map[string]interface {}

...

for k, v := range data {
    fmt.Printf("pair:%s\t%s\n", k, v)   

    switch t := v.(type) {
    case int:
        fmt.Printf("Integer: %v\n", t)
    case float64:
        fmt.Printf("Float64: %v\n", t)
    case string:
        fmt.Printf("String: %v\n", t)
    case bool:
        fmt.Printf("Bool: %v\n", t)
    case []interface {}:
        for i,n := range t {
            fmt.Printf("Item: %v= %v\n", i, n)
        }
    default:
        var r = reflect.TypeOf(t)
        fmt.Printf("Other:%v\n", r)             
    }
}

if you can access the head add <style> /*...some style */ </style> the way Hussein showed you

Be aware "document:keypress" is deprecated. We should use document:keydown instead.

In the list of arguments, each entry must be on its own. Using

output = subprocess.check_output(["ping", "-c","2", "-W","2", "1.1.1.1"])

should fix your problem.

here is a jQuery plugin I came up with:

$.fn.cycle = function(timeout){
    var $all_elem = $(this)

    show_cycle_elem = function(index){
        if(index == $all_elem.length) return; //you can make it start-over, if you want
        $all_elem.hide().eq(index).fadeIn()
        setTimeout(function(){show_cycle_elem(++index)}, timeout);
    }
    show_cycle_elem(0);
}

You need to have a common classname for all the divs you wan to cycle, use it like this:

$("div.cycleme").cycle(5000)

Try this

function checkForm($fields){
        foreach($fields as $field){
            if($field['required'] && strlen($_POST[$field['name']]) <= 0){
                $field['value'] = "Some error";
            }
        }
        return $field;
    }

There isn't, where would it go?

Use CSS to put a border-right on an element if you want something like that.

The top answer is not suitable when values may have length less than 4.

In T-SQL

You will get "Invalid length parameter passed to the right function" because it doesn't accept negatives. Use a CASE statement:

SELECT case when len(foo) >= 4 then RIGHT(foo, LEN(foo) - 4) else '' end AS myfoo from mytable;

In Postgres

Values less than 4 give the surprising behavior below instead of an error, because passing negative values to RIGHT trims the first characters instead of the entire string. It makes more sense to use RIGHT(MyColumn, -5) instead.

An example comparing what you get when you use the top answer's "length - 5" instead of "-5":

create temp table foo (foo) as values ('123456789'),('12345678'),('1234567'),('123456'),('12345'),('1234'),('123'),('12'),('1'), ('');

select foo, right(foo, length(foo) - 5), right(foo, -5) from foo;

foo       len(foo) - 5  just -5   
--------- ------------  -------     
123456789 6789          6789 
12345678  678           678  
1234567   67            67   
123456    6             6    
12345                       
1234      234               
123       3

1. Prepare extra configuration file. Create a file named /etc/systemd/system/docker.service.d/docker.conf. Inside the file docker.conf, paste below content:

[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

Note that if there is no directory like docker.service.d or a file named docker.conf then you should create it.

2. Restart Docker. After saving this file, reload the configuration by systemctl daemon-reload and restart Docker by systemctl restart docker.service.

3. Check your Docker daemon. After restarting docker service, you can see the port in the output of systemctl status docker.service like /usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock.

Hope this may help

Thank you!

You can do this by using /parent::node() in the xpath. Simply append /parent::node() to the child elements xpath.

For example: Let xpath of child element is childElementXpath.

Then xpath of its immediate ancestor would be childElementXpath/parent::node().

Xpath of its next ancestor would be childElementXpath/parent::node()/parent::node()

and so on..

Also, you can navigate to an ancestor of an element using 'childElementXpath/ancestor::*[@attr="attr_value"]'. This would be useful when you have a known child element which is unique but has a parent element which cannot be uniquely identified.

First you define a thread. And if you never call join() or detach() before calling the thread destructor, the program will abort.

As follows, calling a thread destructor without first calling join (to wait for it to finish) or detach is guarenteed to immediately call std::terminate and end the program.

Either implicitly detaching or joining a joinable() thread in its destructor could result in difficult to debug correctness (for detach) or performance (for join) bugs encountered only when an exception is raised. Thus the programmer must ensure that the destructor is never executed while the thread is still joinable.

Seems like a straightforward html menu would be simpler. Use html5 data attributes for values or whatever method you want to store them and css to handle images as backgrounds or put them in the html itself.

Edit: If you are forced to convert from an existing select that you can't get rid of, there are some good plugins as well to modify a select to html. Wijmo and Chosen are a couple that come to mind

Declare receiver as null and then Put register and unregister methods in onResume() and onPause() of the activity respectively.

@Override
protected void onResume() {
    super.onResume();
    if (receiver == null) {
        filter = new IntentFilter(ResponseReceiver.ACTION_RESP);
        filter.addCategory(Intent.CATEGORY_DEFAULT);
        receiver = new ResponseReceiver();
        registerReceiver(receiver, filter);
    }
}      

@Override
protected void onPause() {
    super.onPause();
    if (receiver != null) {
        unregisterReceiver(receiver);
        receiver = null;
    }
}

An index is an on-disk structure associated with a table or view that speeds retrieval of rows from the table or view. An index contains keys built from one or more columns in the table or view. These keys are stored in a structure (B-tree) that enables SQL Server to find the row or rows associated with the key values quickly and efficiently.

Indexes are automatically created when PRIMARY KEY and UNIQUE constraints are defined on table columns. For example, when you create a table with a UNIQUE constraint, Database Engine automatically creates a nonclustered index.

If you configure a PRIMARY KEY, Database Engine automatically creates a clustered index, unless a clustered index already exists. When you try to enforce a PRIMARY KEY constraint on an existing table and a clustered index already exists on that table, SQL Server enforces the primary key using a nonclustered index.

Please refer to this for more information about indexes (clustered and non clustered): https://docs.microsoft.com/en-us/sql/relational-databases/indexes/clustered-and-nonclustered-indexes-described?view=sql-server-ver15

Hope this helps!

Database is like container of data with schema, and schemas is layout of the tables there data types, relations and stuff

Setting net.ipv6.conf.all.forwarding=1 will fix the issue.

This is not quite the answer to this question, but it may be useful for some: as @SWeko said, thanks to covariance and contravariance, List<X> can not be cast in List<Y>, but List<X> can be cast into IEnumerable<Y>, and even with implicit cast.

Example:

List<Y> ListOfY = new List<Y>();
List<X> ListOfX = (List<X>)ListOfY; // Compile error

but

List<Y> ListOfY = new List<Y>();
IEnumerable<X> EnumerableOfX = ListOfY;  // No issue

The big advantage is that it does not create a new list in memory.

Here is the formula I'm using

=IF( ISNUMBER(FIND(".",A1)), LEN(A1) - FIND(".",A1), 0 )

self.materials is a dict and by default you are iterating over just the keys (which are strings).

Since self.materials has more than two keys*, they can't be unpacked into the tuple "k, m", hence the ValueError exception is raised.

In Python 2.x, to iterate over the keys and the values (the tuple "k, m"), we use self.materials.iteritems().

However, since you're throwing the key away anyway, you may as well simply iterate over the dictionary's values:

for m in self.materials.itervalues():

In Python 3.x, prefer dict.values() (which returns a dictionary view object):

for m in self.materials.values():

Run: fuser -k -n tcp 3000

This will kill the process running at the default port 3000.

I don't see this answer here, so I figure I'll add it since I'm leaning Python right now and just discovered it. The Python tutorial (Python 2 in this case) gives the following simple and effective example:

class Employee:
    pass

john = Employee()  # Create an empty employee record

# Fill the fields of the record
john.name = 'John Doe'
john.dept = 'computer lab'
john.salary = 1000

That is, an empty class object is created, then instantiated, and the fields are added dynamically.

The up-side to this is its really simple. The downside is it isn't particularly self-documenting (the intended members aren't listed anywhere in the class "definition"), and unset fields can cause problems when accessed. Those two problems can be solved by:

class Employee:
    def __init__ (self):
        self.name = None # or whatever
        self.dept = None
        self.salary = None

Now at a glance you can at least see what fields the program will be expecting.

Both are prone to typos, john.slarly = 1000 will succeed. Still, it works.

If you only have TypeScript installed for Visual Studio then:

1. Start the Visual Studio Command Prompt
2. Type tsc -v and hit Enter

Visual Studio 2017 versions 15.3 and above bind the TypeScript version to individual projects, as this answer points out:

1. Right click on the project node in Solution Explorer
2. Click Properties
3. Go to the TypeScript Build tab

From: http://wiki.apache.org/httpd/FAQ#Where_can_I_download_.28certified.29_64_bit_Apache_httpd_binaries_for_Windows.3F

Where can I download (certified) 64 bit Apache httpd binaries for Windows?

Right now, there are none. The Apache Software Foundation produces Open Source Software. The 32 bit binaries provided are a courtesy of the community members.

Though there are some unofficial e.g. http://www.apachelounge.com/download/win64/, but I have no idea if they can be trusted.

I tried to require a development branch from a different repository and not the latest version and I had the same issue and non of the above worked for me :(

after a while I saw in the documentation that in cases of dev branch you need to require with a 'dev-' prefix to the version and the following worked perfectly.

composer require [vendorName]/[packageName]:dev-[gitBranchName]

Looking at their docs, they have a $.uniform.update feature to refresh a "uniformed" element.

Example: http://jsfiddle.net/r87NH/4/

$("input:checkbox").uniform();

$("body").on("click", "#check1", function () {
    var two = $("#check2").attr("checked", this.checked);
    $.uniform.update(two);
});

Its a little bit not sophisticated but this should work, for example lets say you want to cap your uilabel to 120x120, with max font size of 28:

magicLabel.numberOfLines = 0;
magicLabel.lineBreakMode = NSLineBreakByWordWrapping;
...
magicLabel.text = text;
    for (int i = 28; i>3; i--) {
        CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:(CGFloat)i] constrainedToSize:CGSizeMake(120.0f, CGFLOAT_MAX) lineBreakMode:NSLineBreakByWordWrapping];
        if (size.height < 120) {
            magicLabel.font = [UIFont systemFontOfSize:(CGFloat)i];
            break;
        }
    }

Or echo 'put {path to file}' | sftp {user}@{host}:{dir}, which would work in both unix and powershell.

You can use a defaultdict for this.

from collections import defaultdict
d = defaultdict(list)
d['key'].append('mykey')

This is slightly more efficient than setdefault since you don't end up creating new lists that you don't end up using. Every call to setdefault is going to create a new list, even if the item already exists in the dictionary.

You need to use a date formatting function for example to_char http://www.postgresql.org/docs/current/static/functions-formatting.html

Yes each consumer can receive the same messages. have a look at http://www.rabbitmq.com/tutorials/tutorial-three-python.html http://www.rabbitmq.com/tutorials/tutorial-four-python.html http://www.rabbitmq.com/tutorials/tutorial-five-python.html

for different ways to route messages. I know they are for python and java but its good to understand the principles, decide what you are doing and then find how to do it in JS. Its sounds like you want to do a simple fanout (tutorial 3), which sends the messages to all queues connected to the exchange.

The difference with what you are doing and what you want to do is basically that you are going to set up and exchange or type fanout. Fanout excahnges send all messages to all connected queues. Each queue will have a consumer that will have access to all the messages separately.

Yes this is commonly done, it is one of the features of AMPQ.

A slight change to Thangamani Palanisamy answer, which allows the Binary reader to be disposed and corrects the input length issue in his comments.

string result = string.Empty;

using (BinaryReader b = new BinaryReader(file.InputStream))
{
  byte[] binData = b.ReadBytes(file.ContentLength);
  result = System.Text.Encoding.UTF8.GetString(binData);
}

For a similar application I had to wrap my data object with JSON.stringify() like this:

data: JSON.stringify({ 
  'foo': 'bar', 
  'ca$libri': 'no$libri'
}),

The API was working with a REST client but couldn't get it to function with jquery ajax in the browser. stringify was the solution.

Although it's often frowned upon, you can technically use:

display: inline !important;

It generally isn't good practice but in some cases might be necessary. What you should do is edit your code so that you aren't applying a style to the <li> elements in the first place.

function foo(value)
{
    var e = document.getElementById('leaveCode');
    if(e) e.value = value;
}

This removes all instances of "-v" from the array sys.argv, and does not complain if no instances were found:

while "-v" in sys.argv:
    sys.argv.remove('-v')

You can see the code in action, in a file called speechToText.py:

$ python speechToText.py -v
['speechToText.py']

$ python speechToText.py -x
['speechToText.py', '-x']

$ python speechToText.py -v -v
['speechToText.py']

$ python speechToText.py -v -v -x
['speechToText.py', '-x']

In my code I didn't really have nice access to the Database object, so you can do it on the DbSet where you also is allowed to use any kind of sql. It will sort of end out like this:

var p = await _db.Persons.FromSql("truncate table Persons;select top 0 * from Persons").ToListAsync();

I'd like to add to the above answers, you could directly use

df = pd.read_fwf('output_list.txt')

fwf stands for fixed width formatted lines.

you define the struct as xyx but you're trying to create the struct called xyz.

I had this because something bad was in my vendor/bundle. Nothing to do with Apache, just in local dev env.

To fix, I deleted vendor\bundle, and also deleted the reference to it in my .bundle/config so it wouldn't get re-used.

Then, I re-bundled (which then installed to GEM_HOME instead of vendor/bundle and the problem went away.

If you want the last 5 rows, ordered in ascending order, you need a subquery:

SELECT *
FROM
    ( SELECT id, name, form_id, DATE(updated_at) AS updated_date, updated_at
      FROM wp_frm_items
      WHERE user_id = 11 
        AND form_id=9
      ORDER BY updated_at DESC
      LIMIT 5
    ) AS tmp
ORDER BY updated_at

After reading the question for 10th time, this may be (just maybe) what you want. Order by Date descending and then order by time (on same date) ascending:

SELECT id, name, form_id, DATE(updated_at) AS updated_date
FROM wp_frm_items
WHERE user_id = 11 
  AND form_id=9
ORDER BY DATE(updated_at) DESC
       , updated_at ASC

Try grabbing the path using: document.location.pathname

In Javascript you can the current URL in parts. Check out: https://css-tricks.com/snippets/javascript/get-url-and-url-parts-in-javascript/

git log --pretty=oneline tagA...tagB (i.e. three dots)

If you just wanted commits reachable from tagB but not tagA:

git log --pretty=oneline tagA..tagB (i.e. two dots)

or

git log --pretty=oneline ^tagA tagB

The ideal is 1 thread per core, as long as none of the threads will block.

One case where this may not be true: there are other threads running on the core, in which case more threads may give your program a bigger slice of the execution time.

Save to EPS and then convert to PDF:

saveas(gcf, 'nombre.eps', 'eps2c')
system('epstopdf nombre.eps') %Needs TeX Live (maybe it works with MiKTeX).

You will need some software that converts EPS to PDF.

As Cody and Brett mentioned, you could reduce VBA slowdown with sensible use of Redim Preserve. Brett suggested Mod to do this.

You can also use a user defined Type and Sub to do this. Consider my code below:

Public Type dsIntArrayType
   eElems() As Integer
   eSize As Integer
End Type

Public Sub PushBackIntArray( _
    ByRef dsIntArray As dsIntArrayType, _
    ByVal intValue As Integer)

    With dsIntArray
    If UBound(.eElems) < (.eSize + 1) Then
        ReDim Preserve .eElems(.eSize * 2 + 1)
    End If
    .eSize = .eSize + 1
    .eElems(.eSize) = intValue
    End With

End Sub

This calls ReDim Preserve only when the size has doubled. The member variable eSize keeps track of the actual data size of eElems. This approach has helped me improve performance when final array length is not known until run time.

Hope this helps others too.

You can put the condition after the WHEN clause, like so:

SELECT
  CASE
    WHEN PAT_ENT.SCR_DT is not null and PAT_ENTRY.ELIGIBILITY is null THEN 'Favor'
    WHEN PAT_ENT.SCR_DT is not null and PAT_ENTRY.EL = 'No' THEN 'Error'
    WHEN PAT_ENTRY.EL = 'Yes' and ISNULL(DS.DES, 'OFF') = 'OFF' THEN 'Active'
    WHEN DS.DES = 'N' THEN 'Early Term'
    WHEN DS.DES = 'Y' THEN 'Complete'
  END
FROM
  ....

Of course, the argument could be made that complex rules like this belong in your business logic layer, not in a stored procedure in the database...

You could use a labeled BREAK statement:

search:
    for (i = 0; i < arrayOfInts.length; i++) {
        for (j = 0; j < arrayOfInts[i].length; j++) {
            if (arrayOfInts[i][j] == searchfor) {
                foundIt = true;
                break search;
            }
        }
    }

However, in properly designed code, you shouldn't need GOTO functionality.

Something that I saw people using is stringexpression > ''. This may be not the fastest one, but happens to be one of the shortest.

Tried it on MS SQL as well as on PostgreSQL.

If you want to keep the original columns Fruit and Name, use reset_index(). Otherwise Fruit and Name will become part of the index.

df.groupby(['Fruit','Name'])['Number'].sum().reset_index()

Fruit   Name       Number
Apples  Bob        16
Apples  Mike        9
Apples  Steve      10
Grapes  Bob        35
Grapes  Tom        87
Grapes  Tony       15
Oranges Bob        67
Oranges Mike       57
Oranges Tom        15
Oranges Tony        1

As seen in the other answers:

df.groupby(['Fruit','Name'])['Number'].sum()

               Number
Fruit   Name         
Apples  Bob        16
        Mike        9
        Steve      10
Grapes  Bob        35
        Tom        87
        Tony       15
Oranges Bob        67
        Mike       57
        Tom        15
        Tony        1

from platform import python_version

print(python_version())

This will give you the exact version of python running your script. eg output:

3.6.5

Just add the column names, yes you can use Null instead but is is a very bad idea to not use column names in any insert, ever.

It's worth noting that even when On Error Resume Next is in effect, the Err object is still populated when an error occurs, so you can still do C-style error handling.

On Error Resume Next

DangerousOperationThatCouldCauseErrors

If Err Then
    WScript.StdErr.WriteLine "error " & Err.Number
    WScript.Quit 1
End If

On Error GoTo 0

None of the above worked for me. I finally solved this problem by renaming favicon.ico to myicon.ico, and reference it in the head <link rel="icon" href="~/myicon.ico" type="image/x-icon" />

Setting a variable to null makes sure to break any references to objects in all browsers including circular references being made between the DOM elements and Javascript scopes. By using delete command we are marking objects to be cleared on the next run of the Garbage collection, but if there are multiple variables referencing the same object, deleting a single variable WILL NOT free the object, it will just remove the linkage between that variable and the object. And on the next run of the Garbage collection, only the variable will be cleaned.

Try this.

document.getElementById("div").onload = alert("This is a div.");

<div id="div">Hello World</div>

Try this one too. You need to remove . from oQuickReply.swap() to make the function working.

document.getElementById("div").onload = oQuickReplyswap();_x000D_
function oQuickReplyswap() {_x000D_
alert("Hello World");_x000D_
}

<div id="div"></div>

Renders the HTML widget of a given field. If you apply this to an entire form or collection of fields, each underlying form row will be rendered.

{# render a field row, but display a label with text "foo" #} {{ form_row(form.name, {'label': 'foo'}) }}

The second argument to form_row() is an array of variables. The templates provided in Symfony only allow to override the label as shown in the example above.

See "More about Form Variables" to learn about the variables argument.

This is the most simple explanation about Dependency Injection and Dependency Injection Container I have ever seen:

Without Dependency Injection

• Application needs Foo (e.g. a controller), so:
• Application creates Foo
• Application calls Foo
  • Foo needs Bar (e.g. a service), so:
  • Foo creates Bar
  • Foo calls Bar
    • Bar needs Bim (a service, a repository, …), so:
    • Bar creates Bim
    • Bar does something

With Dependency Injection

• Application needs Foo, which needs Bar, which needs Bim, so:
• Application creates Bim
• Application creates Bar and gives it Bim
• Application creates Foo and gives it Bar
• Application calls Foo
  • Foo calls Bar
    • Bar does something

Using a Dependency Injection Container

• Application needs Foo so:
• Application gets Foo from the Container, so:
  • Container creates Bim
  • Container creates Bar and gives it Bim
  • Container creates Foo and gives it Bar
• Application calls Foo
  • Foo calls Bar
    • Bar does something

Dependency Injection and dependency Injection Containers are different things:

• Dependency Injection is a method for writing better code
• a DI Container is a tool to help injecting dependencies

You don't need a container to do dependency injection. However a container can help you.

There is a library for this BarCode PHP. You just need to include a few files:

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

You can generate many types of barcodes, namely 1D or 2D. Add the required library:

require_once('class/BCGcode39.barcode.php');

Generate the colours:

// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);

After you have added all the codes, you will get this way:

Example

Since several have asked for an example here is what I was able to do to get it done

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

require_once('class/BCGcode128.barcode.php');

header('Content-Type: image/png');

$color_white = new BCGColor(255, 255, 255);

$code = new BCGcode128();
$code->parse('HELLO');

$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);

$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);

If you want to actually create the image file so you can save it then change

$drawing = new BCGDrawing('', $color_white);

to

$drawing = new BCGDrawing('image.png', $color_white);

All the answers are either wrong or extremely out of date.

The simple and correct way of doing this query is using COUNT_IF function.

SELECT
  COUNT_IF(a IS NULL) AS nulls,
  COUNT_IF(a IS NOT NULL) AS not_nulls
FROM
  us

As taken from the #jquery Freenode IRC channel:

$.each($(form).serializeArray(), function(_, field) { /* use field.name, field.value */ });

Thanks to @Cork on the channel.

I installed 32-bit JVM and retried it again, looks like the following does tell you JVM bitness, not OS arch:

System.getProperty("os.arch");
#
# on a 64-bit Linux box:
# "x86" when using 32-bit JVM
# "amd64" when using 64-bit JVM

This was tested against both SUN and IBM JVM (32 and 64-bit). Clearly, the system property is not just the operating system arch.

A file can be tracked or not, you use hg add to track a file and hg remove or hg forget to un-track it. Using hg remove without flags will both delete the file and un-track it, hg forget will simply un-track it without deleting it.

There is a comprehensive doc for google calendar and other calendar services: https://github.com/InteractionDesignFoundation/add-event-to-calendar-docs/blob/master/services/google.md

An example of working link: https://calendar.google.com/calendar/render?action=TEMPLATE&text=Bithday&dates=20201231T193000Z/20201231T223000Z&details=With%20clowns%20and%20stuff&location=North%20Pole

A ready-to-use method:

/**
* Convert JSONArray to ArrayList<String>.
* 
* @param jsonArray JSON array.
* @return String array.
*/
public static ArrayList<String> toStringArrayList(JSONArray jsonArray) {

  ArrayList<String> stringArray = new ArrayList<String>();
  int arrayIndex;
  JSONObject jsonArrayItem;
  String jsonArrayItemKey;

  for (
    arrayIndex = 0;
    arrayIndex < jsonArray.length();
    arrayIndex++) {

    try {
      jsonArrayItem =
        jsonArray.getJSONObject(
          arrayIndex);

      jsonArrayItemKey =
        jsonArrayItem.getString(
          "name");

      stringArray.add(
        jsonArrayItemKey);
    } catch (JSONException e) {
      e.printStackTrace();
    }
  }

  return stringArray;
}

You must change the cmake C/CXX default FLAGS .

According to CMAKE_BUILD_TYPE={DEBUG/MINSIZEREL/RELWITHDEBINFO/RELEASE} put in the main CMakeLists.txt one of :

For C

set(CMAKE_C_FLAGS_DEBUG "put your flags")
set(CMAKE_C_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_C_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_C_FLAGS_RELEASE "put your flags")

For C++

set(CMAKE_CXX_FLAGS_DEBUG "put your flags")
set(CMAKE_CXX_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_CXX_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_CXX_FLAGS_RELEASE "put your flags")

This will override the values defined in CMakeCache.txt

Open database properties --> options and set Database read-only to False.

• Make sure you logged into the SQL Management Studio using Windows Authentication.
• Make sure your user has write access to the directory of the mdf and log files.

Did the trick for me...

Using MAMP ON Mac, I solve my problem by renaming

/Applications/MAMP/tmp/mysql/mysql.sock.lock

to

/Applications/MAMP/tmp/mysql/mysql.sock

I know this is an old question, but I think found a very simple answer, in case anybody needs it.

If you put string quotes inside your string ("'hello'"), ast_literaleval() will understand it perfectly.

You can use a simple function:

    def doubleStringify(a):
        b = "\'" + a + "\'"
        return b

Or probably more suitable for this example:

    def perfectEval(anonstring):
        try:
            ev = ast.literal_eval(anonstring)
            return ev
        except ValueError:
            corrected = "\'" + anonstring + "\'"
            ev = ast.literal_eval(corrected)
            return ev

It is reasonable to make constructor private if there are other methods that can produce instances. Obvious examples are patterns Singleton (every call return the same instance) and Factory (every call usually create new instance).

1) Best practice is to make new javascript file like my.js. Make this file into your js folder in root directory -> js/my.js . 2) In my.js file add your code inside of $(document).ready(function(){}) scope.

$(document).ready(function(){
    $(".icon-bg").click(function () {
        $(".btn").toggleClass("active");
        $(".icon-bg").toggleClass("active");
        $(".container").toggleClass("active");
        $(".box-upload").toggleClass("active");
        $(".box-caption").toggleClass("active");
        $(".box-tags").toggleClass("active");
        $(".private").toggleClass("active");
        $(".set-time-limit").toggleClass("active");
        $(".button").toggleClass("active");
    });

    $(".button").click(function () {
        $(".button-overlay").toggleClass("active");
    });

    $(".iconmelon").click(function () {
        $(".box-upload-ing").toggleClass("active");
        $(".iconmelon-loaded").toggleClass("active");
    });

    $(".private").click(function () {
        $(".private-overlay").addClass("active");
        $(".private-overlay-wave").addClass("active");
    });
});

3) add your new js file into your html

<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="/js/my.js"></script>
</head>

Simply as bellow;

$this->db->get('table_name')->num_rows();

This will get number of rows/records. however you can use search parameters as well;

$this->db->select('col1','col2')->where('col'=>'crieterion')->get('table_name')->num_rows();

However, it should be noted that you will see bad bad errors if applying as below;

$this->db->get('table_name')->result()->num_rows();

For those who want to just copy and paste the fastest implementation of shift, there is a benchmark and conclusion(see the end). In addition, I introduce fill_value parameter and fix some bugs.

Benchmark

import numpy as np
import timeit

# enhanced from IronManMark20 version
def shift1(arr, num, fill_value=np.nan):
    arr = np.roll(arr,num)
    if num < 0:
        arr[num:] = fill_value
    elif num > 0:
        arr[:num] = fill_value
    return arr

# use np.roll and np.put by IronManMark20
def shift2(arr,num):
    arr=np.roll(arr,num)
    if num<0:
         np.put(arr,range(len(arr)+num,len(arr)),np.nan)
    elif num > 0:
         np.put(arr,range(num),np.nan)
    return arr

# use np.pad and slice by me.
def shift3(arr, num, fill_value=np.nan):
    l = len(arr)
    if num < 0:
        arr = np.pad(arr, (0, abs(num)), mode='constant', constant_values=(fill_value,))[:-num]
    elif num > 0:
        arr = np.pad(arr, (num, 0), mode='constant', constant_values=(fill_value,))[:-num]

    return arr

# use np.concatenate and np.full by chrisaycock
def shift4(arr, num, fill_value=np.nan):
    if num >= 0:
        return np.concatenate((np.full(num, fill_value), arr[:-num]))
    else:
        return np.concatenate((arr[-num:], np.full(-num, fill_value)))

# preallocate empty array and assign slice by chrisaycock
def shift5(arr, num, fill_value=np.nan):
    result = np.empty_like(arr)
    if num > 0:
        result[:num] = fill_value
        result[num:] = arr[:-num]
    elif num < 0:
        result[num:] = fill_value
        result[:num] = arr[-num:]
    else:
        result[:] = arr
    return result

arr = np.arange(2000).astype(float)

def benchmark_shift1():
    shift1(arr, 3)

def benchmark_shift2():
    shift2(arr, 3)

def benchmark_shift3():
    shift3(arr, 3)

def benchmark_shift4():
    shift4(arr, 3)

def benchmark_shift5():
    shift5(arr, 3)

benchmark_set = ['benchmark_shift1', 'benchmark_shift2', 'benchmark_shift3', 'benchmark_shift4', 'benchmark_shift5']

for x in benchmark_set:
    number = 10000
    t = timeit.timeit('%s()' % x, 'from __main__ import %s' % x, number=number)
    print '%s time: %f' % (x, t)

benchmark result:

benchmark_shift1 time: 0.265238
benchmark_shift2 time: 0.285175
benchmark_shift3 time: 0.473890
benchmark_shift4 time: 0.099049
benchmark_shift5 time: 0.052836

Conclusion

shift5 is winner! It's OP's third solution.

In controller you can use MvcHtmlString

public class HomeController : Controller
{
    public ActionResult Index()
    {
        string rawHtml = "<HTML></HTML>";
        ViewBag.EncodedHtml = MvcHtmlString.Create(rawHtml);
        return View();
    }
}

In your View you can simply use that dynamic property which you set in your Controller like below

<div>
        @ViewBag.EncodedHtml
</div>

For cross-platform support, make the command separator (for executing multiple commands on the same line) configurable.

If you're using MinGW on a Windows platform for example, the command separator is &:

NUMBERS = 1 2 3 4
CMDSEP = &
doit:
    $(foreach number,$(NUMBERS),./a.out $(number) $(CMDSEP))

This executes the concatenated commands in one line:

./a.out 1 & ./a.out 2 & ./a.out 3 & ./a.out 4 &

As mentioned elsewhere, on a *nix platform use CMDSEP = ;.

Use parentheses to group the individual branches:

IF EXIST D:\RPS_BACKUP\backups_to_zip\ (goto zipexist) else goto zipexistcontinue

In your case the parser won't ever see the else belonging to the if because goto will happily accept everything up to the end of the command. You can see a similar issue when using echo instead of goto.

Also using parentheses will allow you to use the statements directly without having to jump around (although I wasn't able to rewrite your code to actually use structured programming techniques; maybe it's too early or it doesn't lend itself well to block structures as the code is right now).

Try this, it's working for me.

Sender:

byte[] message = ...
Socket socket = ...
DataOutputStream dOut = new DataOutputStream(socket.getOutputStream());

dOut.writeInt(message.length); // write length of the message
dOut.write(message);           // write the message

Receiver:

Socket socket = ...
DataInputStream dIn = new DataInputStream(socket.getInputStream());

int length = dIn.readInt();                    // read length of incoming message
if(length>0) {
    byte[] message = new byte[length];
    dIn.readFully(message, 0, message.length); // read the message
}

In matplotlib it would be:

import matplotlib.pyplot as plt

data =  [(0, 6.0705199999997801e-08), (1, 2.1015700100300739e-08),
 (2, 7.6280656623374823e-09), (3, 5.7348209304555086e-09),
 (4, 3.6812203579604238e-09), (5, 4.1572516753310418e-09)]

x_val = [x[0] for x in data]
y_val = [x[1] for x in data]

print x_val
plt.plot(x_val,y_val)
plt.plot(x_val,y_val,'or')
plt.show()

which would produce:

This error is probably related to a byte order mark (BOM) prior to the actual XML content. You need to parse the returned String and discard the BOM, so SAXParser can process the document correctly.

You will find a possible solution here.

for line in f

reads all file to a memory, and that can be a problem.

My offer is to change the original source by replacing stripping and checking for empty line. Because if it is not last line - You will receive at least newline character in it ('\n'). And '.strip()' removes it. But in last line of a file You will receive truely empty line, without any characters. So the following loop will not give You false EOF, and You do not waste a memory:

with open("blablabla.txt", "r") as fl_in:
   while True:
      line = fl_in.readline()

        if not line:
            break

The answer to your question is that Tkinter is renamed to tkinter in python3

that is with lowercase t

It's worth mentioning that (at least in python 3), in order for this to work, you must have a file named __init__.py in the same directory.

Here is the example to understand the difference

int i=10;
printf("%d %d",i++,++i);

output: 10 12/11 11 (depending on the order of evaluation of arguments to the printf function, which varies across compilers and architectures)

Explanation: i++->i is printed, and then increments. (Prints 10, but i will become 11) ++i->i value increments and prints the value. (Prints 12, and the value of i also 12)

I had the same problem, but managed to fix it by suppressing the 'Expect: 100-continue' header that cURL usually sends (the following is PHP code, but should work similarly with other cURL APIs):

curl_setopt($curl, CURLOPT_HTTPHEADER, array('Expect:'));

By the way, I am sending calls to the HTTP server that is included in the JDK 6 REST stuff, which has all kinds of problems. In this case, it first sends a 100 response, and then with some requests doesn't send the subsequent 200 response correctly.

First you should check if books itself isn't null, then simply check whether books[i] != null:

if(books==null) throw new IllegalArgumentException();

for (int i = 0; i < books.length; i++){
   if(books[i] != null){
        total += books[i].getPrice();
   }
}

From ggplot2 2.0.0 you can use the margin = argument of element_text() to change the distance between the axis title and the numbers. Set the values of the margin on top, right, bottom, and left side of the element.

ggplot(mpg, aes(cty, hwy)) + geom_point()+
  theme(axis.title.y = element_text(margin = margin(t = 0, r = 20, b = 0, l = 0)))

margin can also be used for other element_text elements (see ?theme), such as axis.text.x, axis.text.y and title.

addition

in order to set the margin for axis titles when the axis has a different position (e.g., with scale_x_...(position = "top"), you'll need a different theme setting - e.g. axis.title.x.top. See https://github.com/tidyverse/ggplot2/issues/4343.

I know this is solved and the question was asked long time ago, but as I'm dealing with a similar problem, I would like to give a totally different approach to this:

For arrays it says "An array is an ordered collection of values." at http://www.json.org/ - but objects ("An object is an unordered set of name/value pairs.") aren't ordered.

I wonder why that object is in an array - that implies an order that's not there.

{
"items":
[
    {
        "WR":"qwe",
        "QU":"asd",
        "QA":"end",
        "WO":"hasd",
        "NO":"qwer"
    },
]
}

So a solution would be to put the keys in a "real" array and add the data as objects to each key like this:

{
"items":
[
    {"WR": {"data": "qwe"}},
    {"QU": {"data": "asd"}},
    {"QA": {"data": "end"}},
    {"WO": {"data": "hasd"}},
    {"NO": {"data": "qwer"}}
]
}

So this is an approach that tries to rethink the original modelling and its intent. But I haven't tested (and I wonder) if all involved tools would preserve the order of that original JSON array.

Try to close all connections to your database first:

use master
ALTER DATABASE BOSEVIKRAM SET SINGLE_USER WITH ROLLBACK IMMEDIATE 

ALTER DATABASE BOSEVIKRAM MODIFY NAME = [BOSEVIKRAM_Deleted]

ALTER DATABASE BOSEVIKRAM_Deleted SET MULTI_USER

Taken from here

You must set your query base to the DN of the user in question, then set your filter to the DN of the group you're wondering if they're a member of. To see if jdoe is a member of the office group then your query will look something like this:

ldapsearch -x -D "ldap_user" -w "user_passwd" -b "cn=jdoe,dc=example,dc=local" -h ldap_host '(memberof=cn=officegroup,dc=example,dc=local)'

If you want to see ALL the groups he's a member of, just request only the 'memberof' attribute in your search, like this:

ldapsearch -x -D "ldap_user" -w "user_passwd" -b "cn=jdoe,dc=example,dc=local" -h ldap_host **memberof**

As a simple alternative, that does not require $.when.apply or an array, you can use the following pattern to generate a single promise for multiple parallel promises:

promise = $.when(promise, anotherPromise);

e.g.

function GetSomeDeferredStuff() {
    // Start with an empty resolved promise (or undefined does the same!)
    var promise;
    var i = 1;
    for (i = 1; i <= 5; i++) {
        var count = i;

        promise = $.when(promise,
        $.ajax({
            type: "POST",
            url: '/echo/html/',
            data: {
                html: "<p>Task #" + count + " complete.",
                delay: count / 2
            },
            success: function (data) {
                $("div").append(data);
            }
        }));
    }
    return promise;
}

$(function () {
    $("a").click(function () {
        var promise = GetSomeDeferredStuff();
        promise.then(function () {
            $("div").append("<p>All done!</p>");
        });
    });
});

Notes:

• I figured this one out after seeing someone chain promises sequentially, using promise = promise.then(newpromise)
• The downside is it creates extra promise objects behind the scenes and any parameters passed at the end are not very useful (as they are nested inside additional objects). For what you want though it is short and simple.
• The upside is it requires no array or array management.

There's a special function n() in dplyr to count rows (potentially within groups):

library(dplyr)
mtcars %>% 
  group_by(cyl, gear) %>% 
  summarise(n = n())
#Source: local data frame [8 x 3]
#Groups: cyl [?]
#
#    cyl  gear     n
#  (dbl) (dbl) (int)
#1     4     3     1
#2     4     4     8
#3     4     5     2
#4     6     3     2
#5     6     4     4
#6     6     5     1
#7     8     3    12
#8     8     5     2

But dplyr also offers a handy count function which does exactly the same with less typing:

count(mtcars, cyl, gear)          # or mtcars %>% count(cyl, gear)
#Source: local data frame [8 x 3]
#Groups: cyl [?]
#
#    cyl  gear     n
#  (dbl) (dbl) (int)
#1     4     3     1
#2     4     4     8
#3     4     5     2
#4     6     3     2
#5     6     4     4
#6     6     5     1
#7     8     3    12
#8     8     5     2

A connected socket is assigned to a new (dedicated) port

That's a common intuition, but it's incorrect. A connected socket is not assigned to a new/dedicated port. The only actual constraint that the TCP stack must satisfy is that the tuple of (local_address, local_port, remote_address, remote_port) must be unique for each socket connection. Thus the server can have many TCP sockets using the same local port, as long as each of the sockets on the port is connected to a different remote location.

See the "Socket Pair" paragraph at: http://books.google.com/books?id=ptSC4LpwGA0C&lpg=PA52&dq=socket%20pair%20tuple&pg=PA52#v=onepage&q=socket%20pair%20tuple&f=false
