For every client you need to start separate thread. Example:

public class ThreadedEchoServer {

    static final int PORT = 1978;

    public static void main(String args[]) {
        ServerSocket serverSocket = null;
        Socket socket = null;

        try {
            serverSocket = new ServerSocket(PORT);
        } catch (IOException e) {
            e.printStackTrace();

        }
        while (true) {
            try {
                socket = serverSocket.accept();
            } catch (IOException e) {
                System.out.println("I/O error: " + e);
            }
            // new thread for a client
            new EchoThread(socket).start();
        }
    }
}

and

public class EchoThread extends Thread {
    protected Socket socket;

    public EchoThread(Socket clientSocket) {
        this.socket = clientSocket;
    }

    public void run() {
        InputStream inp = null;
        BufferedReader brinp = null;
        DataOutputStream out = null;
        try {
            inp = socket.getInputStream();
            brinp = new BufferedReader(new InputStreamReader(inp));
            out = new DataOutputStream(socket.getOutputStream());
        } catch (IOException e) {
            return;
        }
        String line;
        while (true) {
            try {
                line = brinp.readLine();
                if ((line == null) || line.equalsIgnoreCase("QUIT")) {
                    socket.close();
                    return;
                } else {
                    out.writeBytes(line + "\n\r");
                    out.flush();
                }
            } catch (IOException e) {
                e.printStackTrace();
                return;
            }
        }
    }
}

You can also go with more advanced solution, that uses NIO selectors, so you will not have to create thread for every client, but that's a bit more complicated.

Do offline rendering to a texture and evaluate the texture's data. You can find related code by googling for "render to texture" opengl Then use glReadPixels to read the output into an array and perform assertions on it (since looking through such a huge array in the debugger is usually not really useful).

Also you might want to disable clamping to output values that are not between 0 and 1, which is only supported for floating point textures.

I personally was bothered by the problem of properly debugging shaders for a while. There does not seem to be a good way - If anyone finds a good (and not outdated/deprecated) debugger, please let me know.

Best way is to wrap the Image and Paragraph text with a DIV and assign a class.

Example:

<div class="image1">
    <div class="imgWrapper">
        <img src="images/img1.png" width="250" height="444" alt="Screen 1"/>
        <p>It's my first Image</p>
    </div>
    ...
    ...
    ...
    ...
</div>

The others have already said that methods in onClick are searched in activities, not fragments. Nevertheless, if you really want it, it is possible.

Basically, each view has a tag (probably null). We set the root view's tag to the fragment that inflated that view. Then, it is easy to search the view parents and retrieve the fragment containing the clicked button. Now, we find out the method name and use reflection to call the same method from the retrieved fragment. Easy!

in a class that extends Fragment:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_id, container, false);

    OnClickFragments.registerTagFragment(rootView, this); // <========== !!!!!

    return rootView;
}

public void onButtonSomething(View v) {
    Log.d("~~~","~~~ MyFragment.onButtonSomething");
    // whatever
}

all activities are derived from the same ButtonHandlingActivity:

public class PageListActivity extends ButtonHandlingActivity

ButtonHandlingActivity.java:

public class ButtonHandlingActivity extends Activity {

    public void onButtonSomething(View v) {
        OnClickFragments.invokeFragmentButtonHandlerNoExc(v);
//or, if you want to handle exceptions:
//      try {
//          OnClickFragments.invokeFragmentButtonHandler(v);
//      } catch ...
    }

}

It has to define methods for all xml onClick handlers.

com/example/customandroid/OnClickFragments.java:

package com.example.customandroid;

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import android.app.Fragment;
import android.view.View;

public abstract class OnClickFragments {
    public static class FragmentHolder {
        Fragment fragment;
        public FragmentHolder(Fragment fragment) {
            this.fragment = fragment;
        }
    }
    public static Fragment getTagFragment(View view) {
        for (View v = view; v != null; v = (v.getParent() instanceof View) ? (View)v.getParent() : null) {
            Object tag = v.getTag();
            if (tag != null && tag instanceof FragmentHolder) {
                return ((FragmentHolder)tag).fragment;
            }
        }
        return null;
    }
    public static String getCallingMethodName(int callsAbove) {
        Exception e = new Exception();
        e.fillInStackTrace();
        String methodName = e.getStackTrace()[callsAbove+1].getMethodName();
        return methodName;
    }
    public static void invokeFragmentButtonHandler(View v, int callsAbove) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException {
        String methodName = getCallingMethodName(callsAbove+1);
        Fragment f = OnClickFragments.getTagFragment(v);
        Method m = f.getClass().getMethod(methodName, new Class[] { View.class });
        m.invoke(f, v);
    }
    public static void invokeFragmentButtonHandler(View v) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException {
        invokeFragmentButtonHandler(v,1);
    }
    public static void invokeFragmentButtonHandlerNoExc(View v) {
        try {
            invokeFragmentButtonHandler(v,1);
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
    }
    public static void registerTagFragment(View rootView, Fragment fragment) {
        rootView.setTag(new FragmentHolder(fragment));
    }
}

And the next adventure will be proguard obfuscation...

PS

It is of course up to you to design your application so that the data live in the Model rather than in Activities or Fragments (which are Controllers from the MVC, Model-View-Controller point of view). The View is what you define via xml, plus the custom view classes (if you define them, most people just reuse what already is). A rule of thumb: if some data definitely must survive the screen turn, they belong to Model.

1. The degree sign belongs to the number, and not to the "C". You can regard the degree sign as a number symbol, just like the minus sign.
2. There shall not be any space between the digits and the degree sign.
3. There shall be a non-breaking space between the degree sign and the "C".

To make a commit that looks like it was done in the past you have to set both GIT_AUTHOR_DATE and GIT_COMMITTER_DATE:

GIT_AUTHOR_DATE=$(date -d'...') GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE" git commit -m '...'

where date -d'...' can be exact date like 2019-01-01 12:00:00 or relative like 5 months ago 24 days ago.

To see both dates in git log use:

git log --pretty=fuller

This also works for merge commits:

GIT_AUTHOR_DATE=$(date -d'...') GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE" git merge <branchname> --no-ff

MS SQL only short form (since SQL Server 2012):

1=iif( a=b ,1,0)^iif( c=d ,1,0)

use from

Request.Browser

this link will help you :

Detect the browser using ASP.NET and C#

In classic sh, you have to do something like:

s=test1
s="${s}test2"

(there are lots of variations on that theme, like s="$s""test2")

In bash, you can use +=:

s=test1
s+=test2

I think what you want to think about are the various pumping lemmata. A regular language can be recognized by a finite automaton. A context-free language requires a stack, and a context sensitive language requires two stacks (which is equivalent to saying it requires a full Turing machine.)

So, if we think about the pumping lemma for regular languages, what it says, essentially, is that any regular language can be broken down into three pieces, x, y, and z, where all instances of the language are in xy*z (where * is Kleene repetition, ie, 0 or more copies of y.) You basically have one "nonterminal" that can be expanded.

Now, what about context-free languages? There's an analogous pumping lemma for context-free languages that breaks the strings in the language into five parts, uvxyz, and where all instances of the language are in uvⁱxyⁱz, for i ≥ 0. Now, you have two "nonterminals" that can be replicated, or pumped, as long as you have the same number.

I found the problem. This code was placed in a separate file that was added with a php include() function. And this include was happening before the Bootstrap files were loaded. So the Bootstrap JS file was not loaded yet, causing this modal to not do anything.

With the above code sample is nothing wrong and works as intended when placed in the body part of a html page.

<script type="text/javascript">
$('#memberModal').modal('show');
</script>

Change #form to your form's ID

$('#form input').keydown(function(e) {
    if (e.keyCode == 13) {
        $('#form').submit();
    }
});

Or alternatively

$('input').keydown(function(e) {
    if (e.keyCode == 13) {
        $(this).closest('form').submit();
    }
});

Newtonsoft.JSON is a good solution for these kind of situations. Also Newtonsof.JSON is faster than others, such as JavaScriptSerializer, DataContractJsonSerializer.

In this sample, you can the following:

var jsonData = JObject.Parse("your JSON data here");

Then you can cast jsonData to JArray, and you can use a for loop to get data at each iteration.

Also, I want to add something:

for (int i = 0; (JArray)jsonData["data"].Count; i++)
{
    var data = jsonData[i - 1];
}

Working with dynamic object and using Newtonsoft serialize is a good choice.

Just one way that I was able to do it. No guarantee on the safety of your existing data. Try with your own risk.

Delete the data files directly and restart mongod.

For example, with ubuntu (default path to data: /var/lib/mongodb), I had couple files with name like: collection.#. I keep the collection.0 and deleted all others.

Seems an easier way if you don't have serious data in database.

This is the accepted answer written in a decorative way:

Toolkit.getDefaultToolkit()
        .getSystemClipboard()
        .setContents(
                new StringSelection(txtMySQLScript.getText()),
                null
        );

Since Windows >=Vista/Server 2008, RegGetValue is available, which is a safer function than RegQueryValueEx. No need for RegOpenKeyEx, RegCloseKey or NUL termination checks of string values (REG_SZ, REG_MULTI_SZ, REG_EXPAND_SZ).

Its parameter dwFlags supports flags for type restriction, filling the value buffer with zeros on failure (RRF_ZEROONFAILURE) and 32/64bit registry access (RRF_SUBKEY_WOW6464KEY, RRF_SUBKEY_WOW6432KEY) for 64bit programs.

Another easy way to achieve this is to perform a fade using AlphaAnimation.

1. Make your view a ViewGroup
2. Add a child view to it at index 0, with match_parent layout dimensions
3. Give your child the same background as the container
4. Change to background of the container to the target color
5. Fade out the child using AlphaAnimation.
6. Remove the child when the animation is complete (using an AnimationListener)

I had many users controls but one refused to show in the Toolbox, even though I rebuilt the solution and it was checked in the Choose Items... dialog.

Solution:

1. From Solution Explorer I Right-Clicked the offending user control file and selected Exclude From Project
2. Rebuild the solution
3. Right-Click the user control and select Include in Project (assuming you have the Show All Files enabled in the Solution Explorer)

Note this also requires you have the AutoToolboxPopulate option enabled. As @DaveF answer suggests.

Alternate Solution: I'm not sure if this works, and I couldn't try it since I already resolved my issue, but if you unchecked the user control from the Choose Items... dialog, hit OK, then opened it back up and checked the user control. That might also work.

I'm a fan of:

chooseCRANmirror()

Which will print the list of mirrors in the output (no worrying a popup window since you are running it from the terminal) and then you enter the number you want.

When you execute a program the child program inherits its environment variables from the parent. For instance if $HOME is set to /root in the parent then the child's $HOME variable is also set to /root.

This only applies to environment variable that are marked for export. If you set a variable at the command-line like

$ FOO="bar"

That variable will not be visible in child processes. Not unless you export it:

$ export FOO

You can combine these two statements into a single one in bash (but not in old-school sh):

$ export FOO="bar"

Here's a quick example showing the difference between exported and non-exported variables. To understand what's happening know that sh -c creates a child shell process which inherits the parent shell's environment.

$ FOO=bar
$ sh -c 'echo $FOO'

$ export FOO
$ sh -c 'echo $FOO'
bar

Note: To get help on shell built-in commands use help export. Shell built-ins are commands that are part of your shell rather than independent executables like /bin/ls.

I would use spans or float the div left. The only problem with floating is that you have to clear the float afterwards or the containing div must have the overflow style set to auto

For me both these methods didn't work:

• navigationView.getMenu().getItem(0).setChecked(true);
• navigationView.setCheckedItem(id);

Try this one, it works for me.

onNavigationItemSelected(navigationView.getMenu().findItem(R.id.nav_profile));

It's about the ABI, in order to let both C and C++ application use C interfaces without any issue.

Since C language is very easy, code generation was stable for many years for different compilers, such as GCC, Borland C\C++, MSVC etc.

While C++ becomes more and more popular, a lot things must be added into the new C++ domain (for example finally the Cfront was abandoned at AT&T because C could not cover all the features it needs). Such as template feature, and compilation-time code generation, from the past, the different compiler vendors actually did the actual implementation of C++ compiler and linker separately, the actual ABIs are not compatible at all to the C++ program at different platforms.

People might still like to implement the actual program in C++ but still keep the old C interface and ABI as usual, the header file has to declare extern "C" {}, it tells the compiler generate compatible/old/simple/easy C ABI for the interface functions if the compiler is C compiler not C++ compiler.

you can use jquery dialog widget

Through the magic of the semicolon, you can make anything you like a one-liner.

import java.io.PrintWriter
import java.nio.file.Files
import java.nio.file.Paths
import java.nio.charset.StandardCharsets
import java.nio.file.StandardOpenOption
val outfile = java.io.File.createTempFile("", "").getPath
val outstream = new PrintWriter(Files.newBufferedWriter(Paths.get(outfile)
  , StandardCharsets.UTF_8
  , StandardOpenOption.WRITE)); outstream.println("content"); outstream.flush(); outstream.close()

I had to deal with this for my responsive website. I have many different backgrounds for the same elements to deal with different screen widths. My solution is very simple, keep all your images scoped to a css selector, like "zoinked".

The logic:

If user scrolls, then load in styles with background images associated with them. Done!

Here's what I wrote in a library I call "zoinked" I dunno why. It just happened ok?

(function(window, document, undefined) {   var Z = function() {
    this.hasScrolled = false;

    if (window.addEventListener) {
      window.addEventListener("scroll", this, false);
    } else {
      this.load();
    }   };
     Z.prototype.handleEvent = function(e) {
    if ($(window).scrollTop() > 2) {
      this.hasScrolled = true;
      window.removeEventListener("scroll", this);
      this.load();
    }   };
     Z.prototype.load = function() {
    $(document.body).addClass("zoinked");   };
     window.Zoink = Z; 
})(window, document);

For the CSS I'll have all my styles like this:

.zoinked #graphic {background-image: url(large.jpg);}

@media(max-width: 480px) {.zoinked #graphic {background-image: url(small.jpg);}}

My technique with this is to load all the images after the top ones as soon as the user starts to scroll. If you wanted more control you could make the "zoinking" more intelligent.

You can make it so:

type MessageType int32

const (
    TEXT   MessageType = 0
    BINARY MessageType = 1
)

With this code compiler should check type of enum

Since your object type is custom, I would tend to agree with your solution - break it down into smaller segments using an encoding method (like JSON or serializing the content), and on the other end have corresponding code to re-construct the object.

This would work too:

document.getElementsByTagName('p')[0].id

(If element where the 1st paragraph in your document)

A slightly different approach is to create your formula from a string. In the formula help page you will find the following example :

## Create a formula for a model with a large number of variables:
xnam <- paste("x", 1:25, sep="")
fmla <- as.formula(paste("y ~ ", paste(xnam, collapse= "+")))

Then if you look at the generated formula, you will get :

R> fmla
y ~ x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8 + x9 + x10 + x11 + 
    x12 + x13 + x14 + x15 + x16 + x17 + x18 + x19 + x20 + x21 + 
    x22 + x23 + x24 + x25

Markup

<select id="my_select">
    <option value="1">First</option>
    <option value="2">Second</option>
    <option value="3">Third</option>
</select>

jQuery

var my_value = 2;
$('#my_select option').each(function(){
    var $this = $(this); // cache this jQuery object to avoid overhead

    if ($this.val() == my_value) { // if this option's value is equal to our value
        $this.prop('selected', true); // select this option
        return false; // break the loop, no need to look further
    }
});

I don't think adb pull handles wildcards for multiple files. I ran into the same problem and did this by moving the files to a folder and then pulling the folder.

I found a link doing the same thing. Try following these steps.

How to copy selected files from Android with adb pull

As with SQL Server 2012, you can use the built-in format function:

SELECT FORMAT(Minutes/60.0, 'N2')

(just for further readings...)

You can use getElementsByClassName() method for what you want.

var elems = document.getElementsByClassName("a b c");_x000D_
elems[0].style.color = "green";_x000D_
console.log(elems[0]);

<ul>_x000D_
  <li class="a">a</li>_x000D_
  <li class="a b">a, b</li>_x000D_
  <li class="a b c">a, b, c</li>_x000D_
</ul>

This is the fastest solution also. you can see a benchmark about that here.

$('myObject').css({'background-image': 'url(imgUrl)',});

can you try if.else

> col2=ifelse(df1$col=="true",1,0)
> df1
$col
[1] "true"  "false"

> cbind(df1$col)
     [,1]   
[1,] "true" 
[2,] "false"
> cbind(df1$col,col2)
             col2
[1,] "true"  "1" 
[2,] "false" "0" 

Use extern keyword in another .c file.

Add this code at the end of your .htaccess file

RewriteEngine on
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

I still had some issues with other solution presented here. Finally this worked best for me:

<div class="parent">
    <img class="child" src="image.png"/>
</div>

css3:

.child {
 display: block;
 position: absolute;
 top: 50%;
 left: 50%;
 transform: translate(-50%, -50%);
 -webkit-transform: translate(-50%, -50%); /* Safari and Chrome */
 -moz-transform: translate(-50%, -50%); /* Firefox */
 -ms-transform: translate(-50%, -50%); /* IE 9 */
 -o-transform: translate(-50%, -50%); /* Opera */
 // I suppose you may like those too:
 // max-width: 80%;
 // max-height: 80%;
}

You can read more about that approach at this page.

SELECT DATEADD(minute, -15, '2000-01-01 08:30:00'); 

The second value (-15 in this case) must be numeric (i.e. not a string like '00:15'). If you need to subtract hours and minutes I would recommend splitting the string on the : to get the hours and minutes and subtracting using something like

SELECT DATEADD(minute, -60 * @h - @m, '2000-01-01 08:30:00'); 

where @h is the hour part of your string and @m is the minute part of your string

EDIT:

Here is a better way:

SELECT CAST('2000-01-01 08:30:00' as datetime) - CAST('00:15' AS datetime)

I think you should edit the anchor tag on bootstrap.css. Otherwise give customized style to the anchor tag with !important (to override the default style on bootstrap.css).

I found this tutorial very useful. This approach is used by most of jQuery plug-ins.

http://www.htmlgoodies.com/html5/tutorials/create-an-object-oriented-javascript-class-constructor.html#fbid=OVYAQL_TDpK

var Class = function(methods) {   
    var klass = function() {    
        this.initialize.apply(this, arguments);          
    };  

    for (var property in methods) { 
       klass.prototype[property] = methods[property];
    }

    if (!klass.prototype.initialize) klass.prototype.initialize = function(){};      

    return klass;    
};

Now ,

var Person = Class({ 
    initialize: function(name, age) {
        this.name = name;
        this.age  = age;
    },
    toString: function() {
        return "My name is "+this.name+" and I am "+this.age+" years old.";
    }
}); 

var alice = new Person('Alice', 26);
alert(alice.name); //displays "Alice"
alert(alice.age); //displays "26"
alert(alice.toString()); //displays "My name is Alice and I am 26 years old" in most browsers.
//IE 8 and below display the Object's toString() instead! "[Object object]"

The simplest way is as this example:

<div>
   <div style=' height:300px;'>
     SOME LOGO OR CONTENT HERE
   </div>
   <div style='overflow-x: hidden;overflow-y: scroll;'> 
      THIS IS SOME TEXT
   </DIV>

I found Valid OAuth Redirect URIs under PRODUCTS then Facebook Login > Settings not as everyone is stating above. I am supposing this is a version issue.

It still didn't work for me. I guess I really have to add Android Platform rather than just the Website. This is annoying because my app is still in development mode :(

UPDATE: I'm using Expo to develop my react-native app and used info provided here: https://developers.facebook.com/apps/131491964294190/settings/basic/ to set up the Android and iOS platforms. This resolved the issue for me.

If you save the excel file as a CSV file then you can import it into a mysql database using tools such as PHPMyAdmin

Im not sure if this would help in your situation, but a csv file either manually or programatically would be a lot easier to parse into a database than an excel file I would have thought.

EDIT: I would however suggest looking at the other answers rather than mine since @diEcho answer seems more appropriate.

Need to do normal forever start script.js to start, and to check console/error logs use forever logs this will print list of all logs being stored by forever and then you can use tail -f /path/to/logs/file.log and this will print live logs to your window. hit ctrl+z to stop logs print.

I had the same issue.

just removed all my worskspace:

C:\Users\<name>\.<eclipse similar name>

One is non-breaking space and the other is a regular space. A non-breaking space means that the line should not be wrapped at that point, just like it wouldn’t be wrapped in the middle of a word.

Furthermore as Svend points out in his comment, non-breaking spaces are not collapsed.

If you change your inc() function to this

 public static Integer inc(Integer i) {
      Integer iParam = i;
      i = i+1;    // I think that this must be **sneakally** creating a new integer...  
      System.out.println(i == iParam);
      return i;
  }

then you will see that it always prints "false". That means that the addition creates a new instance of Integer and stores it in the local variable i ("local", because i is actually a copy of the reference that was passed), leaving the variable of the calling method untouched.

Integer is an immutable class, meaning that you cannot change it's value but must obtain a new instance. In this case you don't have to do it manually like this:

i = new Integer(i+1); //actually, you would use Integer.valueOf(i.intValue()+1);

instead, it is done by autoboxing.

You don't need jQuery. You can do this using a for loop:

var total = 0;
for (var i = 0; i < someArray.length; i++) {
    total += someArray[i] << 0;
}

my local and remote machines are both OS X. I was having trouble until I checked the file structure of the git repo that xCode Server provides me. Essentially everything is chmod 777 * in that repo so to setup a separate non xCode repo on the same machine in my remote account there I did this:

REMOTE MACHINE

1. Login to your account
2. Create a master dir for all projects 'mkdir git'
3. chmod 775 git then cd into it
4. make a project folder 'mkdir project1'
5. chmod 777 project1 then cd into it
6. run command 'git init' to make the repo
7. this creates a .git dir. do command 'chmod 777 .git' then cd into it
8. run command 'chmod 777 *' to make all files in .git 777 mod
9. cd back out to myproject1 (cd ..)
10. setup a test file in the new repo w/command 'touch test.php'
11. add it to the repo staging area with command 'git add test.php'
12. run command "git commit -m 'new file'" to add file to repo
13. run command 'git status' and you should get "working dir clean" msg
14. cd back to master dir with 'cd ..'
15. in the master dir make a symlink 'ln -s project1 project1.git'
16. run command 'pwd' to get full path
17. in my case the full path was "/Users/myname/git/project1.git'
18. write down the full path for later use in URL
19. exit from the REMOTE MACHINE

LOCAL MACHINE

1. create a project folder somewhere 'newproj1' with 'mkdir newproj1'
2. cd into it
3. run command 'git init'
4. make an alias to the REMOTE MACHINE
5. the alias command format is 'git remote add your_alias_here URL'
6. make sure your URL is correct. This caused me headaches initially
7. URL = 'ssh://[email protected]/Users/myname/git/project1.git'
8. after you do 'git remote add alias URL' do 'git remote -v'
9. the command should respond with a fetch and push line
10. run cmd 'git pull your_alias master' to get test.php from REMOTE repo
11. after the command in #10 you should see a nice message.
12. run command 'git push --set-upstream your_alias master'
13. after command in 12 you should see nice message
14. command in #12 sets up REMOTE as the project master (root)

For me, i learned getting a clean start with a git repo on a LOCAL and REMOTE requires all initial work in a shell first. Then, after the above i was able to easily setup the LOCAL and REMOTE git repos in my IDE and do all the basic git commands using the GUI of the IDE.

I had difficulty until I started at the remote first, then did the local, and until i opened up all the permissions on remote. In addition, having the exact full path in the URL to the symlink was critical to succeed.

Again, this all worked on OS X, local and remote machines.

To summarise all of these answers:

1. Add a single top-level field called // that contains a comment string. This works, but it sucks because you can't put comments near the thing they are commenting on.

2. Add multiple top-level fields starting with //, e.g. //dependencies that contains a comment string. This is better, but it still only allows you to make top-level comments. You can't comment individual dependencies.

3. Add echo commands to your scripts. This works, but it sucks because you can only use it in scripts.

These solutions are also all not very readable. They add a ton of visual noise and IDEs will not syntax highlight them as comments.

I think the only reasonable solution is to generate the package.json from another file. The simplest way is to write your JSON as JavaScript and use Node.js to write it to package.json. Save this file as package.json.mjs, chmod +x it, and then you can just run it to generate your package.json.

#!/usr/bin/env node

import { writeFileSync } from "fs";

const config = {
  // TODO: Think of better name.
  name: "foo",
  dependencies: {
    // Bar 2.0 does not work due to bug 12345.
    bar: "^1.2.0",
  },
  // Look at these beautify comments. Perfectly syntax highlighted, you
  // can put them anywhere and there no risk of some tool removing them.
};

writeFileSync("package.json", JSON.stringify({
    "//": "This file is \x40generated from package.json.mjs; do not edit.",
    ...config
  }, null, 2));

It uses the // key to warn people from editing it. \x40generated is deliberate. It turns into @generated in package.json and means some code review systems will collapse that file by default.

It's an extra step in your build system, but it beats all of the other hacks here.

Almost 5 years after only the direct HTML formatting works for images on GitHub and other markdown options still prevent images from loading when specifying some custom sizes even with the wrong dimensions. I prefer to specify the desired width and get the height calculated automatically, for example,

<img src="https://github.com/your_image.png" alt="Your image title" width="250"/>

Under the "Goto" menu, Control + M is Jump to Matching Bracket. Works for parentheses as well.

You can load HTML page partial, in your case is everything inside div#mytable.

setTimeout(function(){
   $( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds

more information read this http://api.jquery.com/load/

Update Code (if you don't want it auto-refresh)

<button id="refresh-btn">Refresh Table</button>

<script>
$(document).ready(function() {

   function RefreshTable() {
       $( "#mytable" ).load( "your-current-page.html #mytable" );
   }

   $("#refresh-btn").on("click", RefreshTable);

   // OR CAN THIS WAY
   //
   // $("#refresh-btn").on("click", function() {
   //    $( "#mytable" ).load( "your-current-page.html #mytable" );
   // });


});
</script>

If you just want to change alignment of text just make a classes

.left {
text-align: left;
}

and span that class through the text

<span class='left'>aligned left</span>

As Jage's answer removes the element completely, including event handlers and data, I'm adding a simple solution that doesn't do that, thanks to the detach function.

var element = $('#childNode').detach();
$('#parentNode').append(element);

Edit:

Igor Mukhin suggested an even shorter version in the comments below:

$("#childNode").detach().appendTo("#parentNode");

Existing Column

If you want to add a primary key constraint to an existing column all of the previously listed syntax will fail.

To add a primary key constraint to an existing column use the form:

ALTER TABLE `goods`
MODIFY COLUMN `id` INT(10) UNSIGNED PRIMARY KEY AUTO_INCREMENT;

I have the issue like that and my solution is change a little thing in Build Settings:

SWIFT_COMPILATION_MODE = singlefile;
SWIFT_OPTIMIZATION_LEVEL = "-O";

A nice way of doing this with the dataframe api is using the argmax logic like so

  val df = Seq(
    (0,"cat26",30.9), (0,"cat13",22.1), (0,"cat95",19.6), (0,"cat105",1.3),
    (1,"cat67",28.5), (1,"cat4",26.8), (1,"cat13",12.6), (1,"cat23",5.3),
    (2,"cat56",39.6), (2,"cat40",29.7), (2,"cat187",27.9), (2,"cat68",9.8),
    (3,"cat8",35.6)).toDF("Hour", "Category", "TotalValue")

  df.groupBy($"Hour")
    .agg(max(struct($"TotalValue", $"Category")).as("argmax"))
    .select($"Hour", $"argmax.*").show

 +----+----------+--------+
 |Hour|TotalValue|Category|
 +----+----------+--------+
 |   1|      28.5|   cat67|
 |   3|      35.6|    cat8|
 |   2|      39.6|   cat56|
 |   0|      30.9|   cat26|
 +----+----------+--------+

This is so out of date, but in case someone googles this, I have the same issue and figured it out.

If you use KeyEvent Viewer, volume up has a code=24, but a scanCode of 115.

Now my USB controller, only has code=# and all scanCodes are 0. But my airmouse (Mele F10) has all keys with codes and scan codes, but the scancode is what you have to put in the .kl file.

Hope this helps someone out there.

Seems reflection only help here.. I've done small example of converting object to dictionary and vise versa:

[TestMethod]
public void DictionaryTest()
{
    var item = new SomeCLass { Id = "1", Name = "name1" };
    IDictionary<string, object> dict = ObjectToDictionary<SomeCLass>(item);
    var obj = ObjectFromDictionary<SomeCLass>(dict);
}

private T ObjectFromDictionary<T>(IDictionary<string, object> dict)
    where T : class 
{
    Type type = typeof(T);
    T result = (T)Activator.CreateInstance(type);
    foreach (var item in dict)
    {
        type.GetProperty(item.Key).SetValue(result, item.Value, null);
    }
    return result;
}

private IDictionary<string, object> ObjectToDictionary<T>(T item)
    where T: class
{
    Type myObjectType = item.GetType();
    IDictionary<string, object> dict = new Dictionary<string, object>();
    var indexer = new object[0];
    PropertyInfo[] properties = myObjectType.GetProperties();
    foreach (var info in properties)
    {
        var value = info.GetValue(item, indexer);
        dict.Add(info.Name, value);
    }
    return dict;
}

It works for me:

CREATE TABLE `users`(
    `user_id` INT(10) NOT NULL AUTO_INCREMENT,
    `username` VARCHAR(255) NOT NULL,
    `password` VARCHAR(255) NOT NULL,
    PRIMARY KEY (`user_id`)
) ENGINE = MyISAM;       

You could use a for loop:

function isEqual(arr) {
  var first = arr[0];
  for (let i = 1; i < arr.length; i++) {
    if (first !== arr[i]) {
      return false;
    }
  }
  return true;
}

You need to point to the directory instead. You must not specify the dockerfile.

docker build -t ubuntu-test:latest . does work.

docker build -t ubuntu-test:latest ./Dockerfile does not work.

Try this:

$('[id$=lblVessel]').text("NewText");

The id$= will match the elements that end with that text, which is how ASP.NET auto-generates IDs. You can make it safer using span[id=$=lblVessel] but usually this isn't necessary.

Many functions are vectorization already, and so there is no need for any iterations (neither for loops or *pply functions). Your testFunc is one such example. You can simply call:

  testFunc(df[, "x"], df[, "z"])

In general, I would recommend trying such vectorization approaches first and see if they get you your intended results.

Alternatively, if you need to pass multiple arguments to a function which is not vectorized, mapply might be what you are looking for:

  mapply(power.t.test, df[, "x"], df[, "z"])

To add on the earlier comments, I would like to say the following :

The setTimeout() function in JavaScript does not pause execution of the script per se, but merely tells the compiler to execute the code sometime in the future.

There isn't a function that can actually pause execution built into JavaScript. However, you can write your own function that does something like an unconditional loop till the time is reached by using the Date() function and adding the time interval you need.

Here is a pure JavaScript example of picking an image file, displaying it, looping through the image properties, and then re-sizing the image from the canvas into an IMG tag and explicitly setting the re-sized image type to jpeg.

If you right click the top image, in the canvas tag, and choose Save File As, it will default to a PNG format. If you right click, and Save File as the lower image, it will default to a JPEG format. Any file over 400px in width is reduced to 400px in width, and a height proportional to the original file.

HTML

<form class='frmUpload'>
  <input name="picOneUpload" type="file" accept="image/*" onchange="picUpload(this.files[0])" >
</form>

<canvas id="cnvsForFormat" width="400" height="266" style="border:1px solid #c3c3c3"></canvas>
<div id='allImgProperties' style="display:inline"></div>

<div id='imgTwoForJPG'></div>

SCRIPT

<script>

window.picUpload = function(frmData) {
  console.log("picUpload ran: " + frmData);

var allObjtProperties = '';
for (objProprty in frmData) {
    console.log(objProprty + " : " + frmData[objProprty]);
    allObjtProperties = allObjtProperties + "<span>" + objProprty + ": " + frmData[objProprty] + ", </span>";
};

document.getElementById('allImgProperties').innerHTML = allObjtProperties;

var cnvs=document.getElementById("cnvsForFormat");
console.log("cnvs: " + cnvs);
var ctx=cnvs.getContext("2d");

var img = new Image;
img.src = URL.createObjectURL(frmData);

console.log('img: ' + img);

img.onload = function() {
  var picWidth = this.width;
  var picHeight = this.height;

  var wdthHghtRatio = picHeight/picWidth;
  console.log('wdthHghtRatio: ' + wdthHghtRatio);

  if (Number(picWidth) > 400) {
    var newHeight = Math.round(Number(400) * wdthHghtRatio);
  } else {
    return false;
  };

    document.getElementById('cnvsForFormat').height = newHeight;
    console.log('width: 400  h: ' + newHeight);
    //You must change the width and height settings in order to decrease the image size, but
    //it needs to be proportional to the original dimensions.
    console.log('This is BEFORE the DRAW IMAGE');
    ctx.drawImage(img,0,0, 400, newHeight);

    console.log('THIS IS AFTER THE DRAW IMAGE!');

    //Even if original image is jpeg, getting data out of the canvas will default to png if not specified
    var canvasToDtaUrl = cnvs.toDataURL("image/jpeg");
    //The type and size of the image in this new IMG tag will be JPEG, and possibly much smaller in size
    document.getElementById('imgTwoForJPG').innerHTML = "<img src='" + canvasToDtaUrl + "'>";
};
};

</script>

Here is a jsFiddle:

jsFiddle Pick, display, get properties, and Re-size an image file

In jsFiddle, right clicking the top image, which is a canvas, won't give you the same save options as right clicking the bottom image in an IMG tag.

I got the same error because I created a new object from a templated class using the template name without specifying the type explicitly like this:

int main()
{

    MyClass<T> Test2(5.60, 6.6); <- This is wrong
           ^^^
    return 0;
}

The correct way to do it was to specify exactly what T was like this:

int main()
{

    MyClass<double> Test2(5.60, 6.6); <- This is right
            ^^^^^^
    return 0;
}

Try Plugins -> XML Tools -> Pretty Print (libXML) or (XML only - with line breaks Ctrl + Alt + Shift + B)

You may need to install XML Tools using your plugin manager in order to get this option in your menu.

In my experience, libXML gives nice output but only if the file is 100% correctly formed.

If you are using lodash + ES6, here is a one line solution: _.object(window.location.search.replace(/(^\?)/, '').split('&').map(keyVal => keyVal.split('=')));

Solution provided by @Divergent does work, but in my experience it is better to have 2 queries:

1. First for filtering and then grouping by ID to get number of filtered elements. Do not filter here, it is unnecessary.
2. Second query which filters, sorts and paginates.

Solution with pushing $$ROOT and using $slice runs into document memory limitation of 16MB for large collections. Also, for large collections two queries together seem to run faster than the one with $$ROOT pushing. You can run them in parallel as well, so you are limited only by the slower of the two queries (probably the one which sorts).

I have settled with this solution using 2 queries and aggregation framework (note - I use node.js in this example, but idea is the same):

var aggregation = [
  {
    // If you can match fields at the begining, match as many as early as possible.
    $match: {...}
  },
  {
    // Projection.
    $project: {...}
  },
  {
    // Some things you can match only after projection or grouping, so do it now.
    $match: {...}
  }
];


// Copy filtering elements from the pipeline - this is the same for both counting number of fileter elements and for pagination queries.
var aggregationPaginated = aggregation.slice(0);

// Count filtered elements.
aggregation.push(
  {
    $group: {
      _id: null,
      count: { $sum: 1 }
    }
  }
);

// Sort in pagination query.
aggregationPaginated.push(
  {
    $sort: sorting
  }
);

// Paginate.
aggregationPaginated.push(
  {
    $limit: skip + length
  },
  {
    $skip: skip
  }
);

// I use mongoose.

// Get total count.
model.count(function(errCount, totalCount) {
  // Count filtered.
  model.aggregate(aggregation)
  .allowDiskUse(true)
  .exec(
  function(errFind, documents) {
    if (errFind) {
      // Errors.
      res.status(503);
      return res.json({
        'success': false,
        'response': 'err_counting'
      });
    }
    else {
      // Number of filtered elements.
      var numFiltered = documents[0].count;

      // Filter, sort and pagiante.
      model.request.aggregate(aggregationPaginated)

Håken Lid's answer helped solved my problem (thanks!) , in my case present in Python3.7 running Flask in a Docker container (FROM tiangolo/uwsgi-nginx-flask:python3.7-alpine3.7).

In my case, enum34 was being installed by another library (pip install smartsheet-python-sdk). For those coming with a similar Docker container problem, here is my final Dockerfile (stripped to the relevant lines):

FROM tiangolo/uwsgi-nginx-flask:python3.7-alpine3.7
...
RUN pip install -r requirements.txt
RUN pip uninstall -y enum34

The Python tutorial has an appendix called Floating Point Arithmetic: Issues and Limitations. Read it. It explains what is happening and why Python is doing its best. It has even an example that matches yours. Let me quote a bit:

>>> 0.1
0.10000000000000001

you may be tempted to use the round() function to chop it back to the single digit you expect. But that makes no difference:

>>> round(0.1, 1)
0.10000000000000001

The problem is that the binary floating-point value stored for “0.1” was already the best possible binary approximation to 1/10, so trying to round it again can’t make it better: it was already as good as it gets.

Another consequence is that since 0.1 is not exactly 1/10, summing ten values of 0.1 may not yield exactly 1.0, either:

>>> sum = 0.0
>>> for i in range(10):
...     sum += 0.1
...
>>> sum
0.99999999999999989

One alternative and solution to your problems would be using the decimal module.

Plot twist!

You can have orphaned distributed transactions holding exclusive locks and you will not see them if your script assumes there is a session associated with the transaction (there isn't!). Run the script below to identify these transactions:

;WITH ORPHANED_TRAN AS (
SELECT
    dat.name,
    dat.transaction_uow,
    ddt.database_transaction_begin_time,
    ddt.database_transaction_log_bytes_reserved,
    ddt.database_transaction_log_bytes_used
FROM
    sys.dm_tran_database_transactions ddt,
    sys.dm_tran_active_transactions dat,
    sys.dm_tran_locks dtl
WHERE
    ddt.transaction_id = dat.transaction_id AND
    dat.transaction_id = dtl.request_owner_id AND
    dtl.request_session_id = -2 AND
    dtl.request_mode = 'X'
)
SELECT DISTINCT * FROM ORPHANED_TRAN

Once you have identified the transaction, use the transaction_uow column to find it in MSDTC and decide whether to abort or commit it. If the transaction is marked as In Doubt (with a question mark next to it) you will probably want to abort it.

You can also kill the Unit Of Work (UOW) by specifying the transaction_uow in the KILL command:

KILL '<transaction_uow>'

For basic cleanup and re-analyzing you can run "OPTIMIZE TABLE ...", it will compact out the overhead in the indexes and run ANALYZE TABLE too, but it's not going to re-sort them and make them as small & efficient as they could be.

https://dev.mysql.com/doc/refman/8.0/en/optimize-table.html

However, if you want the indexes completely rebuilt for best performance, you can:

1. drop / re-add indexes (obviously)
2. dump / reload the table
3. ALTER TABLE and "change" using the same storage engine
4. REPAIR TABLE (only works for MyISAM, ARCHIVE, and CSV)

https://dev.mysql.com/doc/refman/8.0/en/rebuilding-tables.html

If you do an ALTER TABLE on a field (that is part of an index) and change its type, then it will also fully rebuild the related index(es).

Use the eq selector to selct the nth row (0-based) and add your row after it using after, so:

$('#my_table > tbody:last tr:eq(2)').after(html);

where html is a tr

grep -Fxvf file1 file2

What the flags mean:

-F, --fixed-strings
              Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched.    
-x, --line-regexp
              Select only those matches that exactly match the whole line.
-v, --invert-match
              Invert the sense of matching, to select non-matching lines.
-f FILE, --file=FILE
              Obtain patterns from FILE, one per line.  The empty file contains zero patterns, and therefore matches nothing.

If you recently installed Docker on Windows OS, you need to turn off the Hyper-V feature. See the top answer of VT Not Supported when Installing HAXM

I think you were trying to write a shell script which could take input from stdin. but while you are trying it to do it inline, you got lost trying to create that test= variable. I think it does not make much sense to do it inline, and that's why it does not work the way you expect.

I was trying to reduce

$( ... | head -n $X | tail -n 1 )

to get a specific line from various input. so I could type...

cat program_file.c | line 34

so I need a small shell program able to read from stdin. like you do.

22:14 ~ $ cat ~/bin/line 
#!/bin/sh

if [ $# -ne 1 ]; then echo enter a line number to display; exit; fi
cat | head -n $1 | tail -n 1
22:16 ~ $ 

there you go.

if your exe happens to be a console app, you might be interested in reading the stdout and stderr -- for that, I'll humbly refer you to this example:

http://support.microsoft.com/default.aspx?scid=kb;EN-US;q190351

It's a bit of a mouthful of code, but I've used variations of this code to spawn and read.

Sometimes i've found Intellisense to be slow. Hit the . and wait for a minute and see if it appears after a delay. If so, then I believe there may be a cache that can be deleted to get it to rescan.

Yet another way to use Rscript for *Unix systems is Process Substitution.

Rscript <(zcat a.r)
# [1] "hello"

Which obviously does the same as the accepted answer, but this allows you to manipulate and run your file without saving it the power of the command line, e.g.:

Rscript <(sed s/hello/bye/ a.r)
# [1] "bye"

Similar to Rscript -e "Rcode" it also allows to run without saving into a file. So it could be used in conjunction with scripts that generate R-code, e.g.:

Rscript <(echo "head(iris,2)")
# Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1          5.1         3.5          1.4         0.2  setosa
# 2          4.9         3.0          1.4         0.2  setosa

Use below code to convert String Date to Epoc Timestamp. Note : - Your input Date format should match with SimpleDateFormat.

String inputDateInString= "8/15/2017 12:00:00 AM";
SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyy hh:mm:ss");

Date parsedDate = dateFormat.parse("inputDateInString");

Timestamp timestamp = new java.sql.Timestamp(parsedDate.getTime());

System.out.println("Timestamp "+ timestamp.getTime());

function setMarkers(map,locations){

for (var i = 0; i < locations.length; i++)
 {  

 var loan = locations[i][0];
 var lat = locations[i][1];
 var long = locations[i][2];
 var add =  locations[i][3];

 latlngset = new google.maps.LatLng(lat, long);

 var marker = new google.maps.Marker({  
          map: map, title: loan , position: latlngset  
 });
 map.setCenter(marker.getPosition());


 marker.content = "<h3>Loan Number: " + loan +  '</h3>' + "Address: " + add;


 google.maps.events.addListener(marker,'click', function(map,marker){
          map.infowindow.setContent(marker.content);
          map.infowindow.open(map,marker);

 });

 }
}

Then move var infowindow = new google.maps.InfoWindow() to the initialize() function:

function initialize() {

    var myOptions = {
      center: new google.maps.LatLng(33.890542, 151.274856),
      zoom: 8,
      mapTypeId: google.maps.MapTypeId.ROADMAP

    };
    var map = new google.maps.Map(document.getElementById("default"),
        myOptions);
    map.infowindow = new google.maps.InfoWindow();

    setMarkers(map,locations)

  }

In relational databases, tables are relations (in mathematical meaning). Relations are sets of tuples. Thus table row in relational database is tuple in relation.

Wiki on relations:

In mathematics (more specifically, in set theory and logic), a relation is a property that assigns truth values to combinations (k-tuples) of k individuals. Typically, the property describes a possible connection between the components of a k-tuple. For a given set of k-tuples, a truth value is assigned to each k-tuple according to whether the property does or does not hold.

In RHEL 7, I use this command to filter several ports in LISTEN State:

sudo netstat -tulpn | grep LISTEN | egrep '(8080 |8082 |8083 | etc )'

You could actually do it with javascript but remember js is client side, so you would actually be "warning users" what type of files they can upload, if you want to AVOID (restrict or limit as you said) certain type of files you MUST do it server side.

Look at this basic tut if you would like to get started with server side validation. For the whole tutorial visit this page.

Good luck!

The Unhandled 'error' event is referring not providing a function to the request to pass errors. Without this event the node process ends with the error instead of failing gracefully and providing actual feedback. You can set the event just before the request.write line to catch any issues:

request.on('error', function(err)
{
    console.log(err);
});

Using a for-loop:

• Answers with enumerate and a list comprehension are more pythonic, not necessarily faster, however, this answer is aimed at students who may not be allowed to use some of those built-in functions.
• create an empty list, indices
• create the loop with for i in range(len(x)):, which essentially iterates through a list of index locations [0, 1, 2, 3, ..., len(x)-1]
• in the loop, add any i, where x[i] is a match to value, to indices
  • x[i] accesses the list by index

def get_indices(x: list, value: int) -> list:
    indices = list()
    for i in range(len(x)):
        if x[i] == value:
            indices.append(i)
    return indices

n = [1, 2, 3, -50, -60, 0, 6, 9, -60, -60]
print(get_indices(n, -60))

>>> [4, 8, 9]

• The functions, get_indices, are implemented with type hints. In this case, the list, n, is a bunch of ints, therefore we search for value, also defined as an int.

Using a while-loop and .index:

• With .index, use try-except for error handling, because a ValueError will occur if value is not in the list.

def get_indices(x: list, value: int) -> list:
    indices = list()
    i = 0
    while True:
        try:
            # find an occurrence of value and update i to that index
            i = x.index(value, i)
            # add i to the list
            indices.append(i)
            # advance i by 1
            i += 1
        except ValueError as e:
            break
    return indices

print(get_indices(n, -60))
>>> [4, 8, 9]

This is implementation of methods after decompiling.

    public static bool IsNullOrEmpty(String value) 
    {
        return (value == null || value.Length == 0); 
    }

    public static bool IsNullOrWhiteSpace(String value) 
    {
        if (value == null) return true; 

        for(int i = 0; i < value.Length; i++) { 
            if(!Char.IsWhiteSpace(value[i])) return false; 
        }

        return true;
    }

So it is obvious that IsNullOrWhiteSpace method also checks if value that is being passed contain white spaces.

Whitespaces refer : https://msdn.microsoft.com/en-us/library/system.char.iswhitespace(v=vs.110).aspx

You can try as.vector(t(test)). Please note that, if you want to do it by columns you should use unlist(test).

Apache

1. Run cmd as administrator
2. Go to the Apache bin directory, for example, C:\xampp\apache\bin
3. Run: httpd.exe -k install more information
4. Restart the computer, or run the service manually (from services.msc)

1. Run cmd as administrator
2. Go to the MySQL bin directory, for example, C:\xampp\mysql\bin
3. Run: mysqld.exe --install more information

I'd recommend using nlargest for better performance and shorter code. import pandas

df[col_name].value_counts().nlargest(n=1)

All good and valid courses of investigation especially the logs for more info.

For those hitting this it might be a simple gotcha where when you have created the DB User you may have enforced a password policy and left the user to change the password on first login (i.e. left the checkboxes around the password field at their default values).

Very easily done in SQL Management Studio and can of course cause authentication issues off the bat that are masked unless you look into the logs.

Failed to open stream error occurs because the given path is wrong such as:

$uploadedFile->saveAs(Yii::app()->request->baseUrl.'/images/'.$model->user_photo);

It will give an error if the images folder will not allow you to store images, be sure your folder is readable

This is a very late response, but adds some detail on the previous answers

When it comes to calling static methods in PHP from another static method on the same class, it is important to differentiate between self and the class name.

Take for instance this code:

class static_test_class {
    public static function test() {
        echo "Original class\n";
    }

    public static function run($use_self) {
        if($use_self) {
            self::test();
        } else {
            $class = get_called_class();
            $class::test(); 
        }
    }
}

class extended_static_test_class extends static_test_class {
    public static function test() {
        echo "Extended class\n";
    }
}

extended_static_test_class::run(true);
extended_static_test_class::run(false);

The output of this code is:

Original class

Extended class

This is because self refers to the class the code is in, rather than the class of the code it is being called from.

If you want to use a method defined on a class which inherits the original class, you need to use something like:

$class = get_called_class();
$class::function_name();

I am using IIS and mysql (directly downloaded, without wamp or xampp) My php was installed in c:\php I was getting the error of "call to undefined function mysql_connect()" For me the change of extension_dir worked. This is what I did. In the php.ini, Originally, I had this line

; On windows: extension_dir = "ext"

I changed it to:

; On windows: extension_dir = "C:\php\ext"

And it worked. Of course, I did the other things also like uncommenting the dll extensions etc, as explained in others remarks.

I've faced this issue while undeploying and redeploying a war with glassfish. My class structure was like this,

public interface A{
}

public class AImpl implements A{
}

and it was changed to

public abstract class A{
}

public class AImpl extends A{
}

After stopping and restarting the domain, it worked out fine. I was using glassfish 3.1.43

This work at least in the Debian Jessie image hosted by Google:

The way to enable to switch from you regular to the root user (AKA “super user”) after authentificating with your Google Computer Engine (GCE) User in the local environment (your Linux server in GCE) is pretty straight forward, in fact it just involves just one command to enable it and another every time to use it:

$ sudo passwd
Enter the new UNIX password: <your new root password>
Retype the new UNIX password: <your new root password>
passwd: password updated successfully

After executing the previous command and once logged with your GCE User you will be able to switch to root anytime by just entering the following command:

$ su
Password: <your newly created root password>
root@intance:/#

As we say in economics “caveat emptor” or buyer be aware: Using the root user is far from a best practice in system’s administration. Using it can be the cause a lot of trouble, from wiping everything in your drives and boot disks without a hiccup to many other nasty stuff that would be laborious to backtrack, troubleshoot and rebuilt. On the other hand, I have never met a SysAdmin that doesn’t think he knows better and root more than he should.

REMEMBER: We humans are programmed in such a way that given enough time at one at some point or another are going to press enter without taking into account that we have escalated to root and I can assure you that it will great source of pain, regret and extra work. PLEASE USE ROOT PRIVILEGES SPARSELY AND WITH EXTREME CARE.

Having said all the boring stuff, Have fun, live on the edge, life is short, you only get to live it once, the more you break the more you learn.

I know that this is an old question, but I'm surprised that no answer mentions GetDateTime:

Which you can use like:

while (MyReader.Read())

    TextBox1.Text = MyReader.GetDateTime(columnPosition).ToString("dd/MM/yyyy");
}

Here is a non-recursive solution in C++ that provides the next permutation in ascending order, similarly to the functionality provided by std::next_permutation:

void permute_next(vector<int>& v)
{
  if (v.size() < 2)
    return;

  if (v.size() == 2)
  { 
    int tmp = v[0];
    v[0] = v[1];
    v[1] = tmp;
    return;
  }

  // Step 1: find first ascending-ordered pair from right to left
  int i = v.size()-2;
  while(i>=0)
  { 
    if (v[i] < v[i+1])
      break;
    i--;
  }
  if (i<0) // vector fully sorted in descending order (last permutation)
  {
    //resort in ascending order and return
    sort(v.begin(), v.end());
    return;
  }

  // Step 2: swap v[i] with next higher element of remaining elements
  int pos = i+1;
  int val = v[pos];
  for(int k=i+2; k<v.size(); k++)
    if(v[k] < val && v[k] > v[i])
    {
      pos = k;
      val = v[k];
    }
  v[pos] = v[i];
  v[i] = val;

  // Step 3: sort remaining elements from i+1 ... end
  sort(v.begin()+i+1, v.end());
}

Windows 10 uwp application.

Try this:

webview.Navigate(new Uri("ms-appx-web:///index.html"));

This will work very quickly but will not generate random values but monotonously increasing ones (for a given thread).

import threading

_uid = threading.local()
def genuid():
    if getattr(_uid, "uid", None) is None:
        _uid.tid = threading.current_thread().ident
        _uid.uid = 0
    _uid.uid += 1
    return (_uid.tid, _uid.uid)

It is thread safe and working with tuples may have benefit as opposed to strings (shorter if anything). If you do not need thread safety feel free remove the threading bits (in stead of threading.local, use object() and remove tid altogether).

Hope that helps.

You can use reflection to find all the get methods in your DAO objects and call the equivalent set method in the DTO. This will only work if all such methods exist. It should be easy to find example code for this.

copied from polyfill Array.prototype.find code of Array.find, and added the array as first parameter.

you can pass the search term as predicate function

// Example_x000D_
var listOfObjects = [{key: "1", value: "one"}, {key: "2", value: "two"}]_x000D_

If you can't put value on buttons. I have just a rough solution. Put a hidden field. And when one of the buttons are clicked before submitting, populate the value of hidden field with like say 1 when first button clicked and 2 if second one is clicked. and in submit page check for the value of this hidden field to determine which one is clicked.

Python 3.7.7

import typing
if isinstance([1, 2, 3, 4, 5] , typing.List):
    print("It is a list")

Since variable names in the BASH shell cannot contain a dot or space it is better to use an associative array in BASH like this:

#!/bin/bash

# declare an associative array
declare -A arr

# read file line by line and populate the array. Field separator is "="
while IFS='=' read -r k v; do
   arr["$k"]="$v"
done < app.properties

Testing:

Use declare -p to show the result:

  > declare -p arr  

        declare -A arr='([db.uat.passwd]="secret" [db.uat.user]="saple user" )'

Microsoft windows vista and 7 use NCSI (Network Connectivity Status Indicator) technic:

1. NCSI performs a DNS lookup on www.msftncsi.com, then requests http://www.msftncsi.com/ncsi.txt. This file is a plain-text file and contains only the text 'Microsoft NCSI'.
2. NCSI sends a DNS lookup request for dns.msftncsi.com. This DNS address should resolve to 131.107.255.255. If the address does not match, then it is assumed that the internet connection is not functioning correctly.

1. Right-click an object in Chrome's console and select Store as Global Variable from the context menu. It will return something like temp1 as the variable name.

2. Chrome also has a copy() method, so copy(temp1) in the console should copy that object to your clipboard.

Note on Recursive Objects: If you're trying to copy a recursive object, you will get [object Object]. The way out is to copy(JSON.stringify(temp1)) , the object will be fully copied to your clipboard as a valid JSON, so you'd be able to format it as you wish, using one of many resources.

If you are willing to use an external library, I can't recommend bstrlib enough. It takes a little extra setup, but is easier to use in the long run.

For example, split the string below, one first creates a bstring with the bfromcstr() call. (A bstring is a wrapper around a char buffer). Next, split the string on commas, saving the result in a struct bstrList, which has fields qty and an array entry, which is an array of bstrings.

bstrlib has many other functions to operate on bstrings

Easy as pie...

#include "bstrlib.h"
#include <stdio.h>
int main() {
  int i;
  char *tmp = "Hello,World,sak";
  bstring bstr = bfromcstr(tmp);
  struct bstrList *blist = bsplit(bstr, ',');
  printf("num %d\n", blist->qty);
  for(i=0;i<blist->qty;i++) {
    printf("%d: %s\n", i, bstr2cstr(blist->entry[i], '_'));
  }

}

Yes - absolutely. Looking up a class via reflection is, by magnitude, more expensive.

Quoting Java's documentation on reflection:

Because reflection involves types that are dynamically resolved, certain Java virtual machine optimizations can not be performed. Consequently, reflective operations have slower performance than their non-reflective counterparts, and should be avoided in sections of code which are called frequently in performance-sensitive applications.

Here's a simple test I hacked up in 5 minutes on my machine, running Sun JRE 6u10:

public class Main {

    public static void main(String[] args) throws Exception
    {
        doRegular();
        doReflection();
    }

    public static void doRegular() throws Exception
    {
        long start = System.currentTimeMillis();
        for (int i=0; i<1000000; i++)
        {
            A a = new A();
            a.doSomeThing();
        }
        System.out.println(System.currentTimeMillis() - start);
    }

    public static void doReflection() throws Exception
    {
        long start = System.currentTimeMillis();
        for (int i=0; i<1000000; i++)
        {
            A a = (A) Class.forName("misc.A").newInstance();
            a.doSomeThing();
        }
        System.out.println(System.currentTimeMillis() - start);
    }
}

With these results:

35 // no reflection
465 // using reflection

Bear in mind the lookup and the instantiation are done together, and in some cases the lookup can be refactored away, but this is just a basic example.

Even if you just instantiate, you still get a performance hit:

30 // no reflection
47 // reflection using one lookup, only instantiating

Again, YMMV.

@AlexCuse I wanted to add this as comment to your answer but gave up after making multiple failed attempt to add newlines in comments.

That said, t1ID is unique in table_1 but that doesn't makes it unique in INFO table as well.

For example:

Table_1 has:
Id Field
1 A
2 B

Table_2 has:
Id Field
1 X
2 Y

INFO then can have:
t1ID t2ID field
1 1 some
1 2 data
2 1 in-each
2 2 row

So in INFO table to uniquely identify a row you need both t1ID and t2ID

You may also want to have a look at httplib2, with examples. I find using httplib2 is more concise than using the built-in HTTP modules.

UPDATE: Ruby 1.9.3 Kernel#rand also accepts ranges

rand(a..b)

http://www.rubyinside.com/ruby-1-9-3-introduction-and-changes-5428.html

Converting to array may be too expensive, and it's unnecessary.

(a..b).to_a.sample

Or

[*a..b].sample

Array#sample

Standard in Ruby 1.8.7+.
Note: was named #choice in 1.8.7 and renamed in later versions.

But anyway, generating array need resources, and solution you already wrote is the best, you can do.

Character only takes one value dude! like: char y = 'h'; and maybe you typed like char y = 'hello'; or smthg. good luck. for the question asked above the answer is pretty simple u have to use DOUBLE QUOTES to give a string value. easy enough;)

To store actual Unicode codepoints, you have to first decode the String's UTF-16 codeunits to UTF-32 codeunits (which are currently the same as the Unicode codepoints). Use System.Text.Encoding.UTF32.GetBytes() for that, and then write the resulting bytes to the StringBuilder as needed,i.e.

static void Main(string[] args) 
{ 
    String originalString = "This string contains the unicode character Pi(p)"; 
    Byte[] bytes = Encoding.UTF32.GetBytes(originalString);
    StringBuilder asAscii = new StringBuilder();
    for (int idx = 0; idx < bytes.Length; idx += 4)
    { 
        uint codepoint = BitConverter.ToUInt32(bytes, idx);
        if (codepoint <= 127) 
            asAscii.Append(Convert.ToChar(codepoint)); 
        else 
            asAscii.AppendFormat("\\u{0:x4}", codepoint); 
    } 
    Console.WriteLine("Final string: {0}", asAscii); 
    Console.ReadKey(); 
}

This would also work: hash[hey] = nil

I'm just throwing this answer in there since it solves a problem of mine, it's based off of @stormy's answer, but includes 3 digit country codes and more importantly can be used anywhere in a string, but won't match is it's not preceded by a space/start of the string and ending with a word boundary. This is useful so that it won't match random numbers in the middle of a URL or something

((?:\s|^)(?:\+\d{1,3}\s?)?1?\-?\.?\s?\(?\d{3}\)?[\s.-]?\d{3}[\s.-]?\d{4})(?:\b)

Instinctively one thinks geometrically: horizontal (X) axis and then vertical (Y) axis. This is not, however, the case with a 2D array, rows come first and then columns.

Consider the following analogy: in geometry one walks to the ladder (X axis) and climbs it (Y axis). Conversely, in Java one descends the ladder (rows) and walks away (columns).

Two things. First I don't think you are adding the data that you want to pass to the fragment correctly. What you need to pass to the fragment is a bundle, not an intent. For example if I wanted send an int value to a fragment I would create a bundle, put the int into that bundle, and then set that bundle as an argument to be used when the fragment was created.

Bundle bundle = new Bundle();
bundle.putInt(key, value);
fragment.setArguments(bundle);

Second to retrieve that information you need to get the arguments sent to the fragment. You then extract the value based on the key you identified it with. For example in your fragment:

Bundle bundle = this.getArguments();
if (bundle != null) {
    int i = bundle.getInt(key, defaulValue);
}

What you are getting changes depending on what you put. Also the default value is usually null but does not need to be. It depends on if you set a default value for that argument.

Lastly I do not think you can do this in onCreateView. I think you must retrieve this data within your fragment's onActivityCreated method. My reasoning is as follows. onActivityCreated runs after the underlying activity has finished its own onCreate method. If you are placing the information you wish to retrieve within the bundle durring your activity's onCreate method, it will not exist during your fragment's onCreateView. Try using this in onActivityCreated and just update your ListView contents later.

I know this is an old question, but victorio also asked if there are any other options to copy data from one table to another. There is a very short and fast way to insert all the records from one table to another (which might or might not have similar design).

If you dont have identity column in table B_table:

INSERT INTO A_db.dbo.A_table
SELECT * FROM B_db.dbo.B_table

If you have identity column in table B_table, you have to specify columns to insert. Basically you select all except identity column, which will be auto incremented by default.

In case if you dont have existing B_table in B_db

SELECT *
INTO B_db.dbo.B_table
FROM A_db.dbo.A_table

will create table B_table in database B_db with all existing values

new Date(new Date().setDate(new Date().getDate()-1))

I propose following solution:

DataView view = new DataView(myDataTable); 
view.RowFilter = "RowNo = 1";
DataTable results = view.ToTable(true);

Looking at the DataView Documentation, the first thing we can see is this:

Represents a databindable, customized view of a DataTable for sorting, filtering, searching, editing, and navigation.

What I am getting from this is that DataTable is meant to only store data and DataView is there enable us to "query" against the DataTable.

Here is how this works in this particular case:

You try to implement the SQL Statement

SELECT *
FROM myDataTable
WHERE RowNo = 1

in "DataTable language". In C# we would read it like this:

FROM myDataTable
WHERE RowNo = 1
SELECT *

which looks in C# like this:

DataView view = new DataView(myDataTable);  //FROM myDataTable
view.RowFilter = "RowNo = 1";  //WHERE RowNo = 1
DataTable results = view.ToTable(true);  //SELECT *

There are many ways in which you can create unique keys, the simplest method is to use the index when iterating arrays.

Example

    var lists = this.state.lists.map(function(list, index) {
        return(
            <div key={index}>
                <div key={list.name} id={list.name}>
                    <h2 key={"header"+list.name}>{list.name}</h2>
                    <ListForm update={lst.updateSaved} name={list.name}/>
                </div>
            </div>
        )
    });

Wherever you're lopping over data, here this.state.lists.map, you can pass second parameter function(list, index) to the callback as well and that will be its index value and it will be unique for all the items in the array.

And then you can use it like

<div key={index}>

You can do the same here as well

    var savedLists = this.state.savedLists.map(function(list, index) {
        var list_data = list.data;
        list_data.map(function(data, index) {
            return (
                <li key={index}>{data}</li>
            )
        });
        return(
            <div key={index}>
                <h2>{list.name}</h2>
                <ul>
                    {list_data}
                </ul>
            </div>
        )
    });

Edit

However, As pointed by the user Martin Dawson in the comment below, This is not always ideal.

So whats the solution then?

Many

• You can create a function to generate unique keys/ids/numbers/strings and use that
• You can make use of existing npm packages like uuid, uniqid, etc
• You can also generate random number like new Date().getTime(); and prefix it with something from the item you're iterating to guarantee its uniqueness
• Lastly, I recommend using the unique ID you get from the database, If you get it.

Example:

const generateKey = (pre) => {
    return `${ pre }_${ new Date().getTime() }`;
}

const savedLists = this.state.savedLists.map( list => {
    const list_data = list.data.map( data => <li key={ generateKey(data) }>{ data }</li> );
    return(
        <div key={ generateKey(list.name) }>
            <h2>{ list.name }</h2>
            <ul>
                { list_data }
            </ul>
        </div>
    )
});

To copy a list you can use list(a) or a[:]. In both cases a new object is created.
These two methods, however, have limitations with collections of mutable objects as inner objects keep their references intact:

>>> a = [[1,2],[3],[4]]

>>> b = a[:]
>>> c = list(a)

>>> c[0].append(9)

>>> a
[[1, 2, 9], [3], [4]]
>>> c
[[1, 2, 9], [3], [4]]
>>> b
[[1, 2, 9], [3], [4]]
>>> 

If you want a full copy of your objects you need copy.deepcopy

>>> from copy import deepcopy
>>> a = [[1,2],[3],[4]]

>>> b = a[:]
>>> c = deepcopy(a)

>>> c[0].append(9)

>>> a
[[1, 2], [3], [4]]
>>> b
[[1, 2], [3], [4]]
>>> c
[[1, 2, 9], [3], [4]]
>>> 

A bin is range that represents the width of a single bar of the histogram along the X-axis. You could also call this the interval. (Wikipedia defines them more formally as "disjoint categories".)

The Numpy histogram function doesn't draw the histogram, but it computes the occurrences of input data that fall within each bin, which in turns determines the area (not necessarily the height if the bins aren't of equal width) of each bar.

In this example:

 np.histogram([1, 2, 1], bins=[0, 1, 2, 3])

There are 3 bins, for values ranging from 0 to 1 (excl 1.), 1 to 2 (excl. 2) and 2 to 3 (incl. 3), respectively. The way Numpy defines these bins if by giving a list of delimiters ([0, 1, 2, 3]) in this example, although it also returns the bins in the results, since it can choose them automatically from the input, if none are specified. If bins=5, for example, it will use 5 bins of equal width spread between the minimum input value and the maximum input value.

The input values are 1, 2 and 1. Therefore, bin "1 to 2" contains two occurrences (the two 1 values), and bin "2 to 3" contains one occurrence (the 2). These results are in the first item in the returned tuple: array([0, 2, 1]).

Since the bins here are of equal width, you can use the number of occurrences for the height of each bar. When drawn, you would have:

• a bar of height 0 for range/bin [0,1] on the X-axis,
• a bar of height 2 for range/bin [1,2],
• a bar of height 1 for range/bin [2,3].

You can plot this directly with Matplotlib (its hist function also returns the bins and the values):

>>> import matplotlib.pyplot as plt
>>> plt.hist([1, 2, 1], bins=[0, 1, 2, 3])
(array([0, 2, 1]), array([0, 1, 2, 3]), <a list of 3 Patch objects>)
>>> plt.show()

The answer provided by @DSM is simple and straightforward, but I thought I'd add my own input to this question. If you look at the code for pandas.value_counts, you'll see that there is a lot going on.

If you need to calculate the frequency of many series, this could take a while. A faster implementation would be to use numpy.unique with return_counts = True

Here is an example:

import pandas as pd
import numpy as np

my_series = pd.Series([1,2,2,3,3,3])

print(my_series.value_counts())
3    3
2    2
1    1
dtype: int64

Notice here that the item returned is a pandas.Series

In comparison, numpy.unique returns a tuple with two items, the unique values and the counts.

vals, counts = np.unique(my_series, return_counts=True)
print(vals, counts)
[1 2 3] [1 2 3]

You can then combine these into a dictionary:

results = dict(zip(vals, counts))
print(results)
{1: 1, 2: 2, 3: 3}

And then into a pandas.Series

print(pd.Series(results))
1    1
2    2
3    3
dtype: int64

A one liner but without String.format for all RGB colors:

Color your_color = new Color(128,128,128);

String hex = "#"+Integer.toHexString(your_color.getRGB()).substring(2);

You can add a .toUpperCase()if you want to switch to capital letters. Note, that this is valid (as asked in the question) for all RGB colors.

When you have ARGB colors you can use:

Color your_color = new Color(128,128,128,128);

String buf = Integer.toHexString(your_color.getRGB());
String hex = "#"+buf.substring(buf.length()-6);

A one liner is theoretically also possible but would require to call toHexString twice. I benchmarked the ARGB solution and compared it with String.format():

Get Appliction Name Using RunningAppProcessInfo as:

ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);
List l = am.getRunningAppProcesses();
Iterator i = l.iterator();
PackageManager pm = this.getPackageManager();
while(i.hasNext()) {
  ActivityManager.RunningAppProcessInfo info = (ActivityManager.RunningAppProcessInfo)(i.next());
  try {
    CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA));
    Log.w("LABEL", c.toString());
  }catch(Exception e) {
    //Name Not FOund Exception
  }
}

In my case, this was caused by custom manifest entries added by the maven-jar-plugin.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.6</version>
    <configuration>
        <archive>
            <index>true</index>
            <manifest>
                <addClasspath>true</addClasspath>
            </manifest>
            <manifestEntries>
                <git>${buildNumber}</git>

            </manifestEntries>
        </archive>
    </configuration>
</plugin>

Removing the following entries fixed the problem

<index>true</index>
<manifest>
    <addClasspath>true</addClasspath>
</manifest>

Give an option to ps to display all the processes, an example is:

ps -A | grep "myshellscript.sh"

Check http://www.cyberciti.biz/faq/show-all-running-processes-in-linux/ for more info

And as Basile Starynkevitch mentioned in the comment pgrep is another solution.

You need to anchor the regex at the start and end of the string:

^[0-9]+$

Explanation:

^      # Start of string
[0-9]+ # one or more digits 0-9
$      # End of string

Assuming you mean you want the non-numbers stripped out, you should be able to use something like:

Function onlyDigits(s As String) As String
    ' Variables needed (remember to use "option explicit").   '
    Dim retval As String    ' This is the return string.      '
    Dim i As Integer        ' Counter for character position. '

    ' Initialise return string to empty                       '
    retval = ""

    ' For every character in input string, copy digits to     '
    '   return string.                                        '
    For i = 1 To Len(s)
        If Mid(s, i, 1) >= "0" And Mid(s, i, 1) <= "9" Then
            retval = retval + Mid(s, i, 1)
        End If
    Next

    ' Then return the return string.                          '
    onlyDigits = retval
End Function

Calling this with:

Dim myStr as String
myStr = onlyDigits ("3d1fgd4g1dg5d9gdg")
MsgBox (myStr)

will give you a dialog box containing:

314159

and those first two lines show how you can store it into an arbitrary string variable, to do with as you wish.

Assuming a is a string. The Slice notation in python has the syntax -

list[<start>:<stop>:<step>]

So, when you do a[::-1], it starts from the end towards the first taking each element. So it reverses a. This is applicable for lists/tuples as well.

Example -

>>> a = '1234'
>>> a[::-1]
'4321'

Then you convert it to int and then back to string (Though not sure why you do that) , that just gives you back the string.

You can use the regular expression /(?!$)/:

"overpopulation".split(/(?!$)/)

The negative look-ahead assertion (?!$) will match right in front of every character.

Xcode 8.3.1, Swift 3.1

1. Create a new entry in info.plist "View controller-based status bar appearance" set it to "NO".

2. Open AppDelegate.swift and add these lines in "didFinishLaunchingWithOptions" method:

application.statusBarStyle = .lightContent

I think that your taxonomy is incorrect. There are two opposite types imperative and declarative. Functional is just a subtype of declarative. BTW, wikipedia states the same fact.

The XLSB format is also dedicated to the macros embeded in an hidden workbook file located in excel startup folder (XLSTART).

A quick & dirty test with a xlsm or xlsb in XLSTART folder:

Measure-Command { $x = New-Object -com Excel.Application ;$x.Visible = $True ; $x.Quit() }

0,89s with a xlsb (binary) versus 1,3s with the same content in xlsm format (xml in a zip file) ... :)

To do what you want, using the fs.createWriteStream(path[, options]) function in a ES6 way:

const fs = require('fs');
const writeStream = fs.createWriteStream('file.txt');
const pathName = writeStream.path;
 
let array = ['1','2','3','4','5','6','7'];
  
// write each value of the array on the file breaking line
array.forEach(value => writeStream.write(`${value}\n`));

// the finish event is emitted when all data has been flushed from the stream
writeStream.on('finish', () => {
   console.log(`wrote all the array data to file ${pathName}`);
});

// handle the errors on the write process
writeStream.on('error', (err) => {
    console.error(`There is an error writing the file ${pathName} => ${err}`)
});

// close the stream
writeStream.end();

color = lambda : [random.randint(0, 255), random.randint(0, 255), random.randint(0, 255)]

Like this:

document.getElementById('myTextarea').value = '';

or like this in jQuery:

$('#myTextarea').val('');

Where you have

<textarea id="myTextarea" name="something">This text gets removed</textarea>

For all the downvoters and non-believers:

• Here's the MSDN reference

  value Property: Retrieves or sets the text in the entry field of the textArea element.

• Here's the MDN reference

  value DOMString The raw value contained in the control.

something like this:

#include <iostream>
#include <time.h>

using namespace std;

int main()
{
    const long max_rand = 1000000L;
    double x1 = 12.33, x2 = 34.123, x;

    srandom(time(NULL));

    x = x1 + ( x2 - x1) * (random() % max_rand) / max_rand;

    cout << x1 << " <= " << x << " <= " << x2 << endl;

    return 0;
}

If you don't mind creating an extra date object, you could try:

var tempDate = new Date(parseInt(item.timestamp, 10));
var visitDate = new Date (tempDate.getUTCFullYear(), tempDate.getUTCMonth(), tempDate.getUTCDate());

I do something very similar to get a date of the current month without the time.

I have achieved by something like this

  private void doSomething() {
            List<Action> actions = actionRepository.findAll();
            boolean actionHasFormFields = actions.stream().anyMatch(actionHasMyFieldsPredicate());
            if (actionHasFormFields){
                context.addError(someError);
            }
        }
    }

    private Predicate<Action> actionHasMyFieldsPredicate(){
        return action -> action.getMyField1() != null;
    }

If you have default parameters in your base constructor the base class will be called automatically.

using namespace std;

class Base
{
    public:
    Base(int a=1) : _a(a) {}

    protected:
    int _a;
};

class Derived : public Base
{
  public:
  Derived() {}

  void printit() { cout << _a << endl; }
};

int main()
{
   Derived d;
   d.printit();
   return 0;
}

Output is: 1

Another way to do it is to start a local HTTP server on your directory. On Ubuntu and MacOs with Python installed, it's a one-liner.

Go to the directory containing your web files, and :

python -m SimpleHTTPServer

Then connect to http://localhost:8000/index.html with any web browser to test your page.

Best way to solve this as per my opinion is Using "ignoreReadonly".

First make the input field readonly then add ignoreReadonly:true. This will make sure that even if the text field is readonly , popup will show.

$('#txtStartDate').datetimepicker({
            locale: "da",
            format: "DD/MM/YYYY",
            ignoreReadonly: true
        });
        $('#txtEndDate').datetimepicker({
            locale: "da",
            useCurrent: false,
            format: "DD/MM/YYYY",
            ignoreReadonly: true
        });
});

Using awk

echo $STRING | awk -v N=$N '{print $N}'

Test

% N=3
% STRING="one two three four"
% echo $STRING | awk -v N=$N '{print $N}'
three

Even though this isn't entirely in the SO spirit, I love this question, because I had the same trouble when I started, so I'll give you a quick guide. Obviously you don't understand the principles behind them (don't take it as an offense, but if you did you wouldn't be asking).

Django is server-side. It means, say a client goes to a URL, you have a function inside views that renders what he sees and returns a response in HTML. Let's break it up into examples:

views.py:

def hello(request):
    return HttpResponse('Hello World!')

def home(request):
    return render_to_response('index.html', {'variable': 'world'})

index.html:

<h1>Hello {{ variable }}, welcome to my awesome site</h1>

urls.py:

url(r'^hello/', 'myapp.views.hello'),
url(r'^home/', 'myapp.views.home'),

That's an example of the simplest of usages. Going to 127.0.0.1:8000/hello means a request to the hello() function, going to 127.0.0.1:8000/home will return the index.html and replace all the variables as asked (you probably know all this by now).

Now let's talk about AJAX. AJAX calls are client-side code that does asynchronous requests. That sounds complicated, but it simply means it does a request for you in the background and then handles the response. So when you do an AJAX call for some URL, you get the same data you would get as a user going to that place.

For example, an AJAX call to 127.0.0.1:8000/hello will return the same thing it would as if you visited it. Only this time, you have it inside a JavaScript function and you can deal with it however you'd like. Let's look at a simple use case:

$.ajax({
    url: '127.0.0.1:8000/hello',
    type: 'get', // This is the default though, you don't actually need to always mention it
    success: function(data) {
        alert(data);
    },
    failure: function(data) { 
        alert('Got an error dude');
    }
}); 

The general process is this:

1. The call goes to the URL 127.0.0.1:8000/hello as if you opened a new tab and did it yourself.
2. If it succeeds (status code 200), do the function for success, which will alert the data received.
3. If fails, do a different function.

Now what would happen here? You would get an alert with 'hello world' in it. What happens if you do an AJAX call to home? Same thing, you'll get an alert stating <h1>Hello world, welcome to my awesome site</h1>.

In other words - there's nothing new about AJAX calls. They are just a way for you to let the user get data and information without leaving the page, and it makes for a smooth and very neat design of your website. A few guidelines you should take note of:

1. Learn jQuery. I cannot stress this enough. You're gonna have to understand it a little to know how to handle the data you receive. You'll also need to understand some basic JavaScript syntax (not far from python, you'll get used to it). I strongly recommend Envato's video tutorials for jQuery, they are great and will put you on the right path.
2. When to use JSON?. You're going to see a lot of examples where the data sent by the Django views is in JSON. I didn't go into detail on that, because it isn't important how to do it (there are plenty of explanations abound) and a lot more important when. And the answer to that is - JSON data is serialized data. That is, data you can manipulate. Like I mentioned, an AJAX call will fetch the response as if the user did it himself. Now say you don't want to mess with all the html, and instead want to send data (a list of objects perhaps). JSON is good for this, because it sends it as an object (JSON data looks like a python dictionary), and then you can iterate over it or do something else that removes the need to sift through useless html.
3. Add it last. When you build a web app and want to implement AJAX - do yourself a favor. First, build the entire app completely devoid of any AJAX. See that everything is working. Then, and only then, start writing the AJAX calls. That's a good process that helps you learn a lot as well.
4. Use chrome's developer tools. Since AJAX calls are done in the background it's sometimes very hard to debug them. You should use the chrome developer tools (or similar tools such as firebug) and console.log things to debug. I won't explain in detail, just google around and find out about it. It would be very helpful to you.
5. CSRF awareness. Finally, remember that post requests in Django require the csrf_token. With AJAX calls, a lot of times you'd like to send data without refreshing the page. You'll probably face some trouble before you'd finally remember that - wait, you forgot to send the csrf_token. This is a known beginner roadblock in AJAX-Django integration, but after you learn how to make it play nice, it's easy as pie.

That's everything that comes to my head. It's a vast subject, but yeah, there's probably not enough examples out there. Just work your way there, slowly, you'll get it eventually.

This should do it:

  $time = new DateTime; 

That's how I achieved it, which is not visible (HORRIBLE SOUND....)

<!-- horrible is your mp3 file name any other supported format.-->
<audio controls autoplay hidden="" src="horrible.mp3" type ="audio/mp3"">your browser does not support Html5</audio>

<style>_x000D_
.hideFullColumn tr > .hidecol_x000D_
{_x000D_
    display:none;_x000D_
}_x000D_
</style>

use .hideFullColumn in table and .hidecol in th.You don't need to add class in td individually as it will be problem because index may not be in mind of each td.

If you have two []byte, compare them using bytes.Equal. The Golang documentation says:

Equal returns a boolean reporting whether a and b are the same length and contain the same bytes. A nil argument is equivalent to an empty slice.

Usage:

package main

import (
    "fmt"
    "bytes"
)

func main() {
    a := []byte {1,2,3}
    b := []byte {1,2,3}
    c := []byte {1,2,2}

    fmt.Println(bytes.Equal(a, b))
    fmt.Println(bytes.Equal(a, c))
}

This will print

true
false

Doing

sudo sh -c "echo >> somefile"

should work. The problem is that > and >> are handled by your shell, not by the "sudoed" command, so the permissions are your ones, not the ones of the user you are "sudoing" into.

Replace the rule you have with the following:

div:not(#a) { // add your bg image here //}

The IN was too slow in my situation (180 secs)

So I used a JOIN instead (0.3 secs)

SELECT i.id, i.payer_email
FROM paypal_ipn_orders i
INNER JOIN (
 SELECT payer_email
    FROM paypal_ipn_orders 
    GROUP BY payer_email
    HAVING COUNT( id ) > 1
) j ON i.payer_email=j.payer_email

SQL Server 2008 R2:

For an existing database that you wish to "restore: from a backup of a different database follow these steps:

1. From the toolbar, click the Activity Monitor button.
2. Click processes. Filter by the database you want to restore. Kill all running processes by right clicking on each process and selecting "kill process".
3. Right click on the database you wish to restore, and select Tasks-->Restore-->From Database.
4. Select the "From Device:" radio button.
5. Select ... and choose the backup file of the other database you wish to restore from.
6. Select the backup set you wish to restore from by selecting the check box to the left of the backup set.
7. Select "Options".
8. Select Overwrite the existing database (WITH REPLACE)
9. Important: Change the "Restore As" Rows Data file name to the file name of the existing database you wish to overwrite or just give it a new name.
10. Do the same with the log file file name.
11. Verify from the Activity Monitor Screen that no new processes were spawned. If they were, kill them.
12. Click OK.

Here's the best answer, and the easiest! Put an extra password field in front of your input field and set the display:none , so that when the browser fills it in, it does it in an input that you don't care about.

Change this:

<input type="password" name="password" size="25" class="input" id="password" value="">

to this:

<input type="password" style="display:none;">
<input type="password" name="password" size="25" class="input" id="password" value="">

Since ASP.Net core 1.0 (vNext or whatever name is used for it) sessions are implemented differently. I changed the session timeout value in Startup.cs, void ConfigureServices using:

services.AddSession(options => options.IdleTimeout = TimeSpan.FromSeconds(42));

Or if you want to use the appsettings.json file, you can do something like:

// Appsettings.json
"SessionOptions": {
    "IdleTimeout": "00:30:00"
}

// Startup.cs
services.AddSession(options => options.IdleTimeout = TimeSpan.Parse(Config.GetSection("SessionOptions")["IdleTimeout"]));

The comments state the objective is to print to 2 decimal places.

There's a simple answer for Python 3:

>>> num=3.65
>>> "The number is {:.2f}".format(num)
'The number is 3.65'

or equivalently with f-strings (Python 3.6+):

>>> num = 3.65
>>> f"The number is {num:.2f}"
'The number is 3.65'

As always, the float value is an approximation:

>>> "{}".format(num)
'3.65'
>>> "{:.10f}".format(num)
'3.6500000000'
>>> "{:.20f}".format(num)
'3.64999999999999991118'

I think most use cases will want to work with floats and then only print to a specific precision.

Those that want the numbers themselves to be stored to exactly 2 decimal digits of precision, I suggest use the decimal type. More reading on floating point precision for those that are interested.

Here is OOP:

import MySQLdb


class Database:

    host = 'localhost'
    user = 'root'
    password = '123'
    db = 'test'

    def __init__(self):
        self.connection = MySQLdb.connect(self.host, self.user, self.password, self.db)
        self.cursor = self.connection.cursor()

    def insert(self, query):
        try:
            self.cursor.execute(query)
            self.connection.commit()
        except:
            self.connection.rollback()



    def query(self, query):
        cursor = self.connection.cursor( MySQLdb.cursors.DictCursor )
        cursor.execute(query)

        return cursor.fetchall()

    def __del__(self):
        self.connection.close()


if __name__ == "__main__":

    db = Database()

    #CleanUp Operation
    del_query = "DELETE FROM basic_python_database"
    db.insert(del_query)

    # Data Insert into the table
    query = """
        INSERT INTO basic_python_database
        (`name`, `age`)
        VALUES
        ('Mike', 21),
        ('Michael', 21),
        ('Imran', 21)
        """

    # db.query(query)
    db.insert(query)

    # Data retrieved from the table
    select_query = """
        SELECT * FROM basic_python_database
        WHERE age = 21
        """

    people = db.query(select_query)

    for person in people:
        print "Found %s " % person['name']

Have you had a look at $routeProvider.when('/path',{ resolve:{...}? It can make the promise approach a bit cleaner:

Expose a promise in your service:

app.service('MyService', function($http) {
    var myData = null;

    var promise = $http.get('data.json').success(function (data) {
      myData = data;
    });

    return {
      promise:promise,
      setData: function (data) {
          myData = data;
      },
      doStuff: function () {
          return myData;//.getSomeData();
      }
    };
});

Add resolve to your route config:

app.config(function($routeProvider){
  $routeProvider
    .when('/',{controller:'MainCtrl',
    template:'<div>From MyService:<pre>{{data | json}}</pre></div>',
    resolve:{
      'MyServiceData':function(MyService){
        // MyServiceData will also be injectable in your controller, if you don't want this you could create a new promise with the $q service
        return MyService.promise;
      }
    }})
  }):

Your controller won't get instantiated before all dependencies are resolved:

app.controller('MainCtrl', function($scope,MyService) {
  console.log('Promise is now resolved: '+MyService.doStuff().data)
  $scope.data = MyService.doStuff();
});

I've made an example at plnkr: http://plnkr.co/edit/GKg21XH0RwCMEQGUdZKH?p=preview

You can also paste mayankcpdixit's code in onAnimationComplete option :

// ...
var myDoughnutChart = new Chart(ctx).Doughnut(data, {
    onAnimationComplete: function() {
        ctx.fillText(data[0].value + "%", 100 - 20, 100, 200);
    }
});

Text will be shown after animation

I think you want something like this. The formatting is off, but it should give the essential information you want.

   import java.util.Scanner;
public class BookstoreCredit 
{

   public static void computeDiscount(String name, double gpa) 
   {
      double credits;
      credits = gpa * 10;
      System.out.println(name + " your GPA is " +
         gpa + " so your credit is $" + credits);
   
   }

   public static void main (String args[]) 
   {
      String studentName;
      double gradeAverage;
      Scanner inputDevice = new Scanner(System.in);
      System.out.println("Enter Student name: ");
      studentName = inputDevice.nextLine();
      System.out.println("Enter student GPA: ");
      gradeAverage = inputDevice.nextDouble();  
      
      computeDiscount(studentName, gradeAverage);
   }
}

background-color: rgba(255, 0, 0, 0.5); as mentioned above is the best answer simply put. To say use CSS 3, even in 2013, is not simple because the level of support from various browsers changes with every iteration.

While background-color is supported by all major browsers (not new to CSS 3) [1] the alpha transparency can be tricky, especially with Internet Explorer prior to version 9 and with border color on Safari prior to version 5.1. [2]

Using something like Compass or SASS can really help production and cross platform compatibility.

I had this error, along with others, after I changed my tsconfig.json to target:"es2015", and module:"es2015".

The base (AngularJS2 quickstart) used /// <reference path="../../typings/index.d.ts" /> in the main.ts file. To solve this, I had to remove that line.

Before opening, right-click and choose 'Run as Administrator'. This solved the problem for me.

Remove "strictNullChecks": true from "compilerOptions" or set it to false in the tsconfig.json file of your Ng app. These errors will go away like anything and your app would compile successfully.

Disclaimer: This is just a workaround. This error appears only when the null checks are not handled properly which in any case is not a good way to get things done.

What it worked for me:

    let bar:UINavigationBar! =  self.navigationController?.navigationBar
    self.title = "Whatever..."
    bar.setBackgroundImage(UIImage(), forBarMetrics: UIBarMetrics.Default)
    bar.shadowImage = UIImage()
    bar.alpha = 0.0 

You can use the path module to join the path of the directory in which helper1.js lives to the relative path of foobar.json. This will give you the absolute path to foobar.json.

var fs = require('fs');
var path = require('path');

var jsonPath = path.join(__dirname, '..', 'config', 'dev', 'foobar.json');
var jsonString = fs.readFileSync(jsonPath, 'utf8');

This should work on Linux, OSX, and Windows assuming a UTF8 encoding.

MySQL solution:

select Name from Employee order by Name ;

Order by will order the names from a to z.

If you want to use $(formName).serializeArray() or $(formName).serialize(), you must add name='inputName' on your input element. or will not work!

I needed this to check if the view controller is the current viewed controller, I did it via checking if there's any presented view controller or pushed through the navigator, I'm posting it in case anyone needed such a solution:

if presentedViewController != nil || navigationController?.topViewController != self {
      //Viewcontroller isn't viewed
}else{
     // Now your viewcontroller is being viewed 
}

I'm using this:

String URL = Resources.getSystem().getString(R.string.mess_1);

Here is Bjarne Stroustrup's wordings,

In C++, the definition of NULL is 0, so there is only an aesthetic difference. I prefer to avoid macros, so I use 0. Another problem with NULL is that people sometimes mistakenly believe that it is different from 0 and/or not an integer. In pre-standard code, NULL was/is sometimes defined to something unsuitable and therefore had/has to be avoided. That's less common these days.

If you have to name the null pointer, call it nullptr; that's what it's called in C++11. Then, "nullptr" will be a keyword.

I implore everyone to use Mongoose's query builder language and promises instead of callbacks:

User.find().or([{ name: param }, { nickname: param }])
    .then(users => { /*logic here*/ })
    .catch(error => { /*error logic here*/ })
