1. Ascending order

   Reserved.objects.all().filter(client=client_id).order_by('check_in')
   

2. Descending order

   Reserved.objects.all().filter(client=client_id).order_by('-check_in')
   

- (hyphen) is used to indicate descending order here.

Not a single answer does what was asked in vanilla JS, and I want a vanilla answer so I made it myself.

clientWidth includes padding and offsetWidth includes everything else (jsfiddle link). What you want is to get the computed style (jsfiddle link).

function getInnerWidth(elem) {
    return parseFloat(window.getComputedStyle(elem).width);
}

EDIT: getComputedStyle is non-standard, and can return values in units other than pixels. Some browsers also return a value which takes the scrollbar into account if the element has one (which in turn gives a different value than the width set in CSS). If the element has a scrollbar, you would have to manually calculate the width by removing the margins and paddings from the offsetWidth.

function getInnerWidth(elem) {
    var style = window.getComputedStyle(elem);
    return elem.offsetWidth - parseFloat(style.paddingLeft) - parseFloat(style.paddingRight) - parseFloat(style.borderLeft) - parseFloat(style.borderRight) - parseFloat(style.marginLeft) - parseFloat(style.marginRight);
}

With all that said, this is probably not an answer I would recommend following with my current experience, and I would resort to using methods that don't rely on JavaScript as much.

For me worked changing

builder = new AlertDialog.Builder(getApplicationContext());

to

builder = new AlertDialog.Builder(ThisActivityClassName.this);

Weird thing is that the first one can be found in google tutorial and people get error on this..

You can use the simple mailto, see below for the simple markup.

<a href="mailto:[email protected]">Click here to mail</a>

Once clicked, it will open your Outlook or whatever email client you have set.

What about this : http://support.google.com/maps/bin/answer.py?hl=en&answer=72644

You can use the below query to get a list of table names which uses the specific column in DB2:

SELECT TBNAME                
FROM SYSIBM.SYSCOLUMNS       
WHERE NAME LIKE '%COLUMN_NAME'; 

Note : Here replace the COLUMN_NAME with the column name that you are searching for.

If you want to pass global variables into new scripts, you can create a python file that is only meant for holding global variables (e.g. globals.py). When you import this file at the top of the child script, it should have access to all of those variables.

If you are writing to these variables, then that is a different story. That involves concurrency and locking the variables, which I'm not going to get into unless you want.

Same problem here, for me solution was in editing server.js file line 161

 var server = app.listen(argv.port, '**<server.ip.adress.here>**', function() {
 console.log('Cesium development server running publicly.  Connect to localhost:%d/', server.address().port);
    });

replace localhost> with <server.ip.adress.here>

if you want your check box to keep its height and width but only be invisible:

.hiddenCheckBox{
    visibility: hidden;
}

if you want your check box to be invisible without any with and height:

.hiddenCheckBox{
    display: none;
}

Well in my case I wanted to unit-test the equality operator. I needed call the code under the equality operators without explicitly setting the generic type. Advises for EqualityComparer were not helpful as EqualityComparer called Equals method but not the equality operator.

Here is how I've got this working with generic types by building a LINQ. It calls the right code for == and != operators:

/// <summary>
/// Gets the result of "a == b"
/// </summary>
public bool GetEqualityOperatorResult<T>(T a, T b)
{
    // declare the parameters
    var paramA = Expression.Parameter(typeof(T), nameof(a));
    var paramB = Expression.Parameter(typeof(T), nameof(b));
    // get equality expression for the parameters
    var body = Expression.Equal(paramA, paramB);
    // compile it
    var invokeEqualityOperator = Expression.Lambda<Func<T, T, bool>>(body, paramA, paramB).Compile();
    // call it
    return invokeEqualityOperator(a, b);
}

/// <summary>
/// Gets the result of "a =! b"
/// </summary>
public bool GetInequalityOperatorResult<T>(T a, T b)
{
    // declare the parameters
    var paramA = Expression.Parameter(typeof(T), nameof(a));
    var paramB = Expression.Parameter(typeof(T), nameof(b));
    // get equality expression for the parameters
    var body = Expression.NotEqual(paramA, paramB);
    // compile it
    var invokeInequalityOperator = Expression.Lambda<Func<T, T, bool>>(body, paramA, paramB).Compile();
    // call it
    return invokeInequalityOperator(a, b);
}

It really depends on the type of HTML file you're creating.

For such tasks, I use to create an object, serialize it to XML, then transform it with XSL. The pros of this approach are:

• The strict separation between source code and HTML template,
• The possibility to edit HTML without having to recompile the application,
• The ability to serve different HTML in different cases based on the same XML, or even serve XML directly when needed (for a further deserialization for example),
• The shorter amount of code to write.

The cons are:

• You must know XSLT and know how to implement it in Java.
• You must write XSLT (and it's torture for many developers).
• When transforming XML to HTML with XSLT, some parts may be tricky. Few examples: <textarea/> tags (which make the page unusable), XML declaration (which can cause problems with IE), whitespace (with <pre></pre> tags etc.), HTML entities ( ), etc.
• The performance will be reduced, since serialization to XML wastes lots of CPU resources and XSL transformation is very costly too.

Now, if your HTML is very short or very repetitive or if the HTML has a volatile structure which changes dynamically, this approach must not be taken in account. On the other hand, if you serve HTML files which have all a similar structure and you want to reduce the amount of Java code and use templates, this approach may work.

I have been having this same problem for a few days and many uploads, seemed to work when I logged out of apple developer portal on my PC (which I use instead of my Mac to view the portal) upload the new version via my Mac and log into the developer portal on the Mac I was using to upload the ipa, seemed to work straight away after that, guess apple just really hates Windows or being logged in from a different computer is a problem.

Schleis' variant does not work for me (Ubuntu 12.04), so let me propose my (clear and shiny :) variants:

Variant 1 (I would prefer this option):

git for-each-ref --format='%(refname:short) %(upstream)' refs/heads/ | awk '$2 !~/^refs\/remotes/' | xargs git branch -D 

Variant 2:

a. Dry-run:

comm -23 <( git branch | grep -v "/" | grep -v "*" | sort ) <( git br -r | awk -F '/' '{print $2}' | sort ) | awk '{print "git branch -D " $1}'

b. Remove branches:

comm -23 <( git branch | grep -v "/" | grep -v "*" | sort ) <( git br -r | awk -F '/' '{print $2}' | sort ) | xargs git branch -D

I had same as issue. I use Git Totoise. Just Right Click ->TotoiseGit -> Clean Up . Now you can push to Github It worked fine with me :D

Getting the text the user has selected is relatively simple. There's no benefit to be gained by involving jQuery since you need nothing other than the window and document objects.

function getSelectionText() {
    var text = "";
    if (window.getSelection) {
        text = window.getSelection().toString();
    } else if (document.selection && document.selection.type != "Control") {
        text = document.selection.createRange().text;
    }
    return text;
}

If you're interested in an implementation that will also deal with selections in <textarea> and texty <input> elements, you could use the following. Since it's now 2016 I'm omitting the code required for IE <= 8 support but I've posted stuff for that in many places on SO.

function getSelectionText() {_x000D_
    var text = "";_x000D_
    var activeEl = document.activeElement;_x000D_
    var activeElTagName = activeEl ? activeEl.tagName.toLowerCase() : null;_x000D_
    if (_x000D_
      (activeElTagName == "textarea") || (activeElTagName == "input" &&_x000D_
      /^(?:text|search|password|tel|url)$/i.test(activeEl.type)) &&_x000D_
      (typeof activeEl.selectionStart == "number")_x000D_
    ) {_x000D_
        text = activeEl.value.slice(activeEl.selectionStart, activeEl.selectionEnd);_x000D_
    } else if (window.getSelection) {_x000D_
        text = window.getSelection().toString();_x000D_
    }_x000D_
    return text;_x000D_
}_x000D_
_x000D_
document.onmouseup = document.onkeyup = document.onselectionchange = function() {_x000D_
  document.getElementById("sel").value = getSelectionText();_x000D_
};

Selection:_x000D_
<br>_x000D_
<textarea id="sel" rows="3" cols="50"></textarea>_x000D_
<p>Please select some text.</p>_x000D_
<input value="Some text in a text input">_x000D_
<br>_x000D_
<input type="search" value="Some text in a search input">_x000D_
<br>_x000D_
<input type="tel" value="4872349749823">_x000D_
<br>_x000D_
<textarea>Some text in a textarea</textarea>

if my_list is the list that you want to store your objects in it and my_object is your object wanted to be stored, use this structure:

my_list.append(my_object)

Here is how I do it:

Also when I hit the post(Config.getURL("login"), values) the app seems to pause for a while (seems weird - thought the idea behind a service was that it runs on a different thread!)

In this case its better to use asynctask, which runs on a different thread and return result back to the ui thread on completion.

Per Arvand:
Eclipse: Simply type android.R.layout.simple_list_item_1 somewhere in code, hold Ctrl, hover over simple_list_item_1, and from the dropdown that appears select Open declaration in layout/simple_list_item_1.xml. It'll direct you to the contents of the XML.

From there, if you then hover over the resulting simple_list_item_1.xml tab in the Editor, you'll see the file is located at C:\Data\applications\Android\android-sdk\platforms\android-19\data\res\layout\simple_list_item_1.xml (or equivalent location for your installation).

This brings to mind Steve Yegge's Execution in the Kingdom of Nouns. It basically states that Java needs an object for every action, and therefore does not have "verb-only" entities like function pointers.

if all things were said didn't work, go back to basics and test if this is working:

<html>
  <head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
  </head>
  <body>
    <script type="text/javascript">
      $('body').click(function() {
        // do something here like:
        alert('hey! The body click is working!!!')
      });
    </script>
  </body>
</html>

then tell me if its working or not.

I've discovered in Excel 2007, if the results are a Table from an embedded query, the ss.000 does not work. I can paste the query results (from SQL Server Management Studio), and format the time just fine. But when I embed the query as a Data Connection in Excel, the format always gives .000 as the milliseconds.

Laravel 5 gets its enviroment related variables from the .env file located in the root of your project. You just need to set APP_ENV to whatever you want, for example:

APP_ENV=development

This is used to identify the current enviroment. If you want to display errors, you'll need to enable debug mode in the same file:

APP_DEBUG=true

The role of the .env file is to allow you to have different settings depending on which machine you are running your application. So on your production server, the .env file settings would be different from your local development enviroment.

You should not expose this info. in public, specially api keys. It may lead to a privacy leak.

Before making the website public you should hide it. You can do it in 2 or more ways

1. Complex coding/hiding
2. Simply put firebase SDK codes at bottom of your website or app thus firebase automatically does all works. you don't need to put API keys anywhere

Short Answer

Your i will be converted to an unsigned integer by adding UINT_MAX + 1, then the addition will be carried out with the unsigned values, resulting in a large result (depending on the values of u and i).

Long Answer

According to the C99 Standard:

6.3.1.8 Usual arithmetic conversions

1. If both operands have the same type, then no further conversion is needed.
2. Otherwise, if both operands have signed integer types or both have unsigned integer types, the operand with the type of lesser integer conversion rank is converted to the type of the operand with greater rank.
3. Otherwise, if the operand that has unsigned integer type has rank greater or equal to the rank of the type of the other operand, then the operand with signed integer type is converted to the type of the operand with unsigned integer type.
4. Otherwise, if the type of the operand with signed integer type can represent all of the values of the type of the operand with unsigned integer type, then the operand with unsigned integer type is converted to the type of the operand with signed integer type.
5. Otherwise, both operands are converted to the unsigned integer type corresponding to the type of the operand with signed integer type.

In your case, we have one unsigned int (u) and signed int (i). Referring to (3) above, since both operands have the same rank, your i will need to be converted to an unsigned integer.

6.3.1.3 Signed and unsigned integers

1. When a value with integer type is converted to another integer type other than _Bool, if the value can be represented by the new type, it is unchanged.
2. Otherwise, if the new type is unsigned, the value is converted by repeatedly adding or subtracting one more than the maximum value that can be represented in the new type until the value is in the range of the new type.
3. Otherwise, the new type is signed and the value cannot be represented in it; either the result is implementation-defined or an implementation-defined signal is raised.

Now we need to refer to (2) above. Your i will be converted to an unsigned value by adding UINT_MAX + 1. So the result will depend on how UINT_MAX is defined on your implementation. It will be large, but it will not overflow, because:

6.2.5 (9)

A computation involving unsigned operands can never overflow, because a result that cannot be represented by the resulting unsigned integer type is reduced modulo the number that is one greater than the largest value that can be represented by the resulting type.

Bonus: Arithmetic Conversion Semi-WTF

#include <stdio.h>

int main(void)
{
  unsigned int plus_one = 1;
  int minus_one = -1;

  if(plus_one < minus_one)
    printf("1 < -1");
  else
    printf("boring");

  return 0;
}

You can use this link to try this online: https://repl.it/repls/QuickWhimsicalBytes

Bonus: Arithmetic Conversion Side Effect

Arithmetic conversion rules can be used to get the value of UINT_MAX by initializing an unsigned value to -1, ie:

unsigned int umax = -1; // umax set to UINT_MAX

This is guaranteed to be portable regardless of the signed number representation of the system because of the conversion rules described above. See this SO question for more information: Is it safe to use -1 to set all bits to true?

NOTE: Before trying this code, please find this line in the below code:

private static String DB_NAME ="YourDbName"; // Database name

DB_NAME here is the name of your database. It is assumed that you have a copy of the database in the assets folder, so for example, if your database name is ordersDB, then the value of DB_NAME will be ordersDB,

private static String DB_NAME ="ordersDB";

Keep the database in assets folder and then follow the below:

DataHelper class:

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import android.content.Context;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;

public class DataBaseHelper extends SQLiteOpenHelper {

    private static String TAG = "DataBaseHelper"; // Tag just for the LogCat window
    private static String DB_NAME ="YourDbName"; // Database name
    private static int DB_VERSION = 1; // Database version
    private final File DB_FILE;
    private SQLiteDatabase mDataBase;
    private final Context mContext;

    public DataBaseHelper(Context context) {
        super(context, DB_NAME, null, DB_VERSION);
        DB_FILE = context.getDatabasePath(DB_NAME);
        this.mContext = context;
    }

    public void createDataBase() throws IOException {
        // If the database does not exist, copy it from the assets.
        boolean mDataBaseExist = checkDataBase();
        if(!mDataBaseExist) {
            this.getReadableDatabase();
            this.close();
            try {
                // Copy the database from assests
                copyDataBase();
                Log.e(TAG, "createDatabase database created");
            } catch (IOException mIOException) {
                throw new Error("ErrorCopyingDataBase");
            }
        }
    }

    // Check that the database file exists in databases folder
    private boolean checkDataBase() {
        return DB_FILE.exists();
    }

    // Copy the database from assets
    private void copyDataBase() throws IOException {
        InputStream mInput = mContext.getAssets().open(DB_NAME);
        OutputStream mOutput = new FileOutputStream(DB_FILE);
        byte[] mBuffer = new byte[1024];
        int mLength;
        while ((mLength = mInput.read(mBuffer)) > 0) {
            mOutput.write(mBuffer, 0, mLength);
        }
        mOutput.flush();
        mOutput.close();
        mInput.close();
    }

    // Open the database, so we can query it
    public boolean openDataBase() throws SQLException {
        // Log.v("DB_PATH", DB_FILE.getAbsolutePath());
        mDataBase = SQLiteDatabase.openDatabase(DB_FILE, null, SQLiteDatabase.CREATE_IF_NECESSARY);
        // mDataBase = SQLiteDatabase.openDatabase(DB_FILE, null, SQLiteDatabase.NO_LOCALIZED_COLLATORS);
        return mDataBase != null;
    }

    @Override
    public synchronized void close() {
        if(mDataBase != null) {
            mDataBase.close();
        }
        super.close();
    }

}

Write a DataAdapter class like:

import java.io.IOException;
import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.util.Log;

public class TestAdapter {

    protected static final String TAG = "DataAdapter";

    private final Context mContext;
    private SQLiteDatabase mDb;
    private DataBaseHelper mDbHelper;

    public TestAdapter(Context context) {
        this.mContext = context;
        mDbHelper = new DataBaseHelper(mContext);
    }

    public TestAdapter createDatabase() throws SQLException {
        try {
            mDbHelper.createDataBase();
        } catch (IOException mIOException) {
            Log.e(TAG, mIOException.toString() + "  UnableToCreateDatabase");
            throw new Error("UnableToCreateDatabase");
        }
        return this;
    }

    public TestAdapter open() throws SQLException {
        try {
            mDbHelper.openDataBase();
            mDbHelper.close();
            mDb = mDbHelper.getReadableDatabase();
        } catch (SQLException mSQLException) {
            Log.e(TAG, "open >>"+ mSQLException.toString());
            throw mSQLException;
        }
        return this;
    }

    public void close() {
        mDbHelper.close();
    }

     public Cursor getTestData() {
         try {
             String sql ="SELECT * FROM myTable";
             Cursor mCur = mDb.rawQuery(sql, null);
             if (mCur != null) {
                mCur.moveToNext();
             }
             return mCur;
         } catch (SQLException mSQLException) {
             Log.e(TAG, "getTestData >>"+ mSQLException.toString());
             throw mSQLException;
         }
     }
}

Now you can use it like:

TestAdapter mDbHelper = new TestAdapter(urContext);
mDbHelper.createDatabase();
mDbHelper.open();

Cursor testdata = mDbHelper.getTestData();

mDbHelper.close();

EDIT: Thanks to JDx

For Android 4.1 (Jelly Bean), change:

DB_PATH = "/data/data/" + context.getPackageName() + "/databases/";

to:

DB_PATH = context.getApplicationInfo().dataDir + "/databases/";

in the DataHelper class, this code will work on Jelly Bean 4.2 multi-users.

EDIT: Instead of using hardcoded path, we can use

DB_PATH = context.getDatabasePath(DB_NAME).getAbsolutePath();

which will give us the full path to the database file and works on all Android versions

in some cases you need to uninstall and install node-sass library. Try:

npm uninstall --save node-sass

and

npm install --save node-sass

look at this its work for me, Stack link here

Can't* believe this question has existed for 9 years without anyone suggesting a simple recursive function:

def walk_days(start_date, end_date):
    if start_date <= end_date:
        print(start_date.strftime("%Y-%m-%d"))
        next_date = start_date + timedelta(days=1)
        walk_days(next_date, end_date)

#demo
start_date = datetime(2009, 5, 30)
end_date   = datetime(2009, 6, 9)

walk_days(start_date, end_date)

Output:

2009-05-30
2009-05-31
2009-06-01
2009-06-02
2009-06-03
2009-06-04
2009-06-05
2009-06-06
2009-06-07
2009-06-08
2009-06-09

As of Chrome 80, none of the current answers work. There is no visible "Pause" button - you need to long-click the "Play" button to access the Stop icon:

It's an awesome detailed reply by Janusz. But just for the sake of people who are coming to this page for answers, the easier way is at http://android-holo-colors.com/ (dead link) linked from Android Asset Studio

A good description of all the tools are at AndroidOnRocks.com (site offline now)

However, I highly recommend everybody to read the reply from Janusz as it will make understanding clearer. Use the tool to do stuffs real quick

All you need to do is :

arr.join('');

FIDDLE

I had significant headaches with these methods before, I recommend you avoid any variant of UrlEncode, and instead use Uri.EscapeDataString - at least that one has a comprehensible behavior.

Let's see...

HttpUtility.UrlEncode(" ") == "+" //breaks ASP.NET when used in paths, non-
                                  //standard, undocumented.
Uri.EscapeUriString("a?b=e") == "a?b=e" // makes sense, but rarely what you
                                        // want, since you still need to
                                        // escape special characters yourself

But my personal favorite has got to be HttpUtility.UrlPathEncode - this thing is really incomprehensible. It encodes:

• " " ==> "%20"
• "100% true" ==> "100%%20true" (ok, your url is broken now)
• "test A.aspx#anchor B" ==> "test%20A.aspx#anchor%20B"
• "test A.aspx?hmm#anchor B" ==> "test%20A.aspx?hmm#anchor B" (note the difference with the previous escape sequence!)

It also has the lovelily specific MSDN documentation "Encodes the path portion of a URL string for reliable HTTP transmission from the Web server to a client." - without actually explaining what it does. You are less likely to shoot yourself in the foot with an Uzi...

In short, stick to Uri.EscapeDataString.

create a new java project in Eclipse and copy .java files to its src directory, if you don't know where those source files should be placed, right click on the root of the project and choose new->class to create a test class and see where its .java file is placed, then put other files with it, in the same directory, you may have to adjust the package in those source files according to the new project directory structure.

if you use external libraries in your code, you have two options: either copy / download jar files or use maven if you use maven you'll have to create the project at maven project in the first place, creating java projects as maven projects are the way to go anyway but that's for another post...

Let's see, I sorted that on a different way. in my case I had as path something like ~/.local/bin which seems that it is not the way it wants.

Try to use the full path, like /Users/tobias/.local/bin, I mean, change the PATH variable from ~/.local/bin to /Users/tobias/.local/bin or $HOME/.local/bin .

Now it works.

The following syntax can also be used if the array is not named (just the array is passed to the template):

  <ul id="luke_should_be_here">
  {{this.1.name}}
  </ul>

All your problems derive from this

byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());
return encrypted;

Which are enclosed in a try, catch block, the problem is that in case the program found an exception you are not returning anything. Put it like this (modify it as your program logic stands):

public static byte[] encrypt(String toEncrypt) throws Exception{
    try{
        String plaintext = toEncrypt;
        String key = "01234567890abcde";
        String iv = "fedcba9876543210";

        SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
        IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());

        Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");
        cipher.init(Cipher.ENCRYPT_MODE,keyspec,ivspec);
        byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());

        return encrypted;
    } catch(Exception e){
        return null;            // Always must return something
    }
}

For the second one you must catch the Exception from the encrypt method call, like this (also modify it as your program logic stands):

public void actionPerformed(ActionEvent e)
  .
  .
  .
    try {
        byte[] encrypted = encrypt(concatURL);
        String encryptedString = bytesToHex(encrypted);
        content.removeAll();
        content.add(new JLabel("Concatenated User Input -->" + concatURL));

        content.add(encryptedTextField);
    setContentPane(content);
    } catch (Exception exc) {
        // TODO: handle exception
    }
}

The lessons you must learn from this:

• A method with a return-type must always return an object of that type, I mean in all possible scenarios
• All checked exceptions must always be handled

You do not need to select the columns separately in order to use them in your CONCAT. Simply remove them, and your query will become:

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

Before

return $_config[0] =& $config; 

After

$_config[0] =& $config;
return $_config[0]; 

Update

Added by NikiC

In PHP assignment expressions always return the assigned value. So $_config[0] =& $config returns $config - but not the variable itself, but a copy of its value. And returning a reference to a temporary value wouldn't be particularly useful (changing it wouldn't do anything).

Update

This fix has been merged into CI 2.2.1 (https://github.com/bcit-ci/CodeIgniter/commit/69b02d0f0bc46e914bed1604cfbd9bf74286b2e3). It's better to upgrade rather than modifying core framework files.

You can of course format the result of current_timestamp(). Please have a look at the various formatting functions in the official documentation.

Use JSON_UNESCAPED_UNICODE inside json_encode() if your php version >=5.4.

Here is a snippet of code I often use. It returns the full available screen area (even on multi-monitor setups) while retaining the native monitor positions.

public static Rectangle getMaximumScreenBounds() {
    int minx=0, miny=0, maxx=0, maxy=0;
    GraphicsEnvironment environment = GraphicsEnvironment.getLocalGraphicsEnvironment();
    for(GraphicsDevice device : environment.getScreenDevices()){
        Rectangle bounds = device.getDefaultConfiguration().getBounds();
        minx = Math.min(minx, bounds.x);
        miny = Math.min(miny, bounds.y);
        maxx = Math.max(maxx,  bounds.x+bounds.width);
        maxy = Math.max(maxy, bounds.y+bounds.height);
    }
    return new Rectangle(minx, miny, maxx-minx, maxy-miny);
}

On a computer with two full-HD monitors, where the left one is set as the main monitor (in Windows settings), the function returns

java.awt.Rectangle[x=0,y=0,width=3840,height=1080]

On the same setup, but with the right monitor set as the main monitor, the function returns

java.awt.Rectangle[x=-1920,y=0,width=3840,height=1080]

As other people have mentioned, ArrayList has a constructor that takes a collection of items, and adds all of them. Here's the documentation:

http://java.sun.com/javase/6/docs/api/java/util/ArrayList.html#ArrayList%28java.util.Collection%29

So you need to do:

ArrayList<MyNode> myNodeList = new ArrayList<MyNode>(this.getVertices());

However, in another comment you said that was giving you a compiler error. It looks like your class MyGraph is a generic class. And so getVertices() actually returns type V, not type myNode.

I think your code should look like this:

public V getNode(int nodeId){
        ArrayList<V> myNodeList = new ArrayList<V>(this.getVertices());
        return myNodeList(nodeId);
}

But, that said it's a very inefficient way to extract a node. What you might want to do is store the nodes in a binary tree, then when you get a request for the nth node, you do a binary search.

jQuery.load() is probably the easiest way to load data asynchronously using a selector, but you can also use any of the jquery ajax methods (get, post, getJSON, ajax, etc.)

Note that load allows you to use a selector to specify what piece of the loaded script you want to load, as in

$("#mydiv").load(location.href + " #mydiv");

Note that this technically does load the whole page and jquery removes everything but what you have selected, but that's all done internally.

Add this Annotation to Entity Class (Model) that works for me this cause lazy loading via the hibernate proxy object.

@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})

If you assign parent type to a subclass it means that you agree with to use the common features of the parent class.

It gives you the freedom to abstract from different subclass implementations. As a result limits you with the parent features.

However, this type of assignment is called upcasting.

Parent parent = new Child();  

The opposite is downcasting.

Child child = (Child)parent;

So, if you create instance of Child and downcast it to Parent you can use that type attribute name. If you create instance of Parent you can do the same as with previous case but you can't use salary because there's not such attribute in the Parent. Return to the previous case that can use salary but only if downcasting to Child.

There's more detail explanation

Multiple columns in a key are going to, in general, perform more poorly than a surrogate key. I prefer to have a surrogate key and then a unique index on a multicolumn key. That way you can have better performance and the uniqueness needed is maintained. And even better, when one of the values in that key changes, you don't also have to update a million child entries in 215 child tables.

Here is the Python Doc for datetime object using dateutil package..

from dateutil.parser import parse

get_date_obj = parse("2012-11-01T04:16:13-04:00")
print get_date_obj

There are 2 ways of doing this

foreach($questions as $key => $question){
    $questions[$key]['answers'] = $answers_model->get_answers_by_question_id($question['question_id']);
}

This way you save the key, so you can update it again in the main $questions variable

or

foreach($questions as &$question){

Adding the & will keep the $questions updated. But I would say the first one is recommended even though this is shorter (see comment by Paystey)

Per the PHP foreach documentation:

In order to be able to directly modify array elements within the loop precede $value with &. In that case the value will be assigned by reference.

As noted earlier, there is an option to turn on or off History provided you open up task manager under the elevated "Administrator" mode (right click on the Task Scheduler program/shortcut and choose "Run As Administrator"). Then under "Tasks" is your spot to stop or start History.

I'm a big fan of using EPPlus to perform these types of actions. EPPlus is a library you can reference in your project and easily create/modify spreadsheets on a server. I use it for any project that requires an export function.

Here's a nice blog entry that shows how to use the library, though the library itself should come with some samples that explain how to use it.

Third party libraries are a lot easier to use than Microsoft COM objects, in my opinion. I would suggest giving it a try.

Use Where-Object and test the $_.CreationTime:

Get-ChildItem 'PATH' -recurse -include @("*.tif*","*.jp2","*.pdf") | 
    Where-Object { $_.CreationTime -ge "03/01/2013" -and $_.CreationTime -le "03/31/2013" }

I recently needed to do a System Restore and it caused several of my files to change/disappear that I had been working on since the restore. Some of those were DLL files. I used Source Control to retrieve the entire project but I still had a similar issue as above. I found this answer that described you may need to remove a DLL and readd it to get your errors fixed. This was the case in my scenario.

Removing WebMatrix.WebData and readding it as well as adding in WebMatrix.Data fixed my error of The type or namespace name 'Data' does not exist in the namespace 'WebMatrix' ....

With a jQuery implementation you can EASILY remove the default values when it is time to submit. Below is an example:

$('#submit').click(function(){
   var text = this.attr('placeholder');
   var inputvalue = this.val();  // you need to collect this anyways
   if (text === inputvalue) inputvalue = "";

   // $.ajax(...  // do your ajax thing here

});

I know that you are looking for an overlay, but you might prefer the ease of this route (now knowing what I wrote above). If so, then I wrote this for my own projects and it works really nice (requires jQuery) and takes just a couple minutes to implement for your entire site. It offers grey text at first, light grey when in focus, and black when typing. It also offers the placeholder text whenever the input field is empty.

First set up your form and include your placeholder attributes on the input tags.

<input placeholder="enter your email here">

Just copy this code and save it as placeholder.js.

(function( $ ){

   $.fn.placeHolder = function() {  
      var input = this;
      var text = input.attr('placeholder');  // make sure you have your placeholder attributes completed for each input field
      if (text) input.val(text).css({ color:'grey' });
      input.focus(function(){  
         if (input.val() === text) input.css({ color:'lightGrey' }).selectRange(0,0).one('keydown', function(){     
            input.val("").css({ color:'black' });  
         });
      });
      input.blur(function(){ 
         if (input.val() == "" || input.val() === text) input.val(text).css({ color:'grey' }); 
      }); 
      input.keyup(function(){ 
        if (input.val() == "") input.val(text).css({ color:'lightGrey' }).selectRange(0,0).one('keydown', function(){
            input.val("").css({ color:'black' });
        });               
      });
      input.mouseup(function(){
        if (input.val() === text) input.selectRange(0,0); 
      });   
   };

   $.fn.selectRange = function(start, end) {
      return this.each(function() {
        if (this.setSelectionRange) { this.setSelectionRange(start, end);
        } else if (this.createTextRange) {
            var range = this.createTextRange();
            range.collapse(true); 
            range.moveEnd('character', end); 
            range.moveStart('character', start); 
            range.select(); 
        }
      });
   };

})( jQuery );

To use on just one input

$('#myinput').placeHolder();  // just one

This is how I recommend you implement it on all input fields on your site when the browser does not support HTML5 placeholder attributes:

var placeholder = 'placeholder' in document.createElement('input');  
if (!placeholder) {      
  $.getScript("../js/placeholder.js", function() {   
      $(":input").each(function(){   // this will work for all input fields
        $(this).placeHolder();
      });
  });
} 

use this polyfill https://github.com/UziTech/js-date-format

var d = new Date("1/1/2014 10:00 am");
d.format("DDDD 'the' DS 'of' MMMM YYYY h:mm TT");
//output: Wednesday the 1st of January 2014 10:00 AM

First, make sure you have Tkinter module installed.

sudo apt-get install python-tk

In python 2 the package name is Tkinter not tkinter.

from Tkinter import *

ref: http://www.techinfected.net/2015/09/how-to-install-and-use-tkinter-in-ubuntu-debian-linux-mint.html

Organize your files in hierarchical directories and then just use relative paths.

Demo:

HTML (index.html)

<a href='inner/file.html'>link</a>

Directory structure:

base/
base/index.html
base/inner/file.html
....

Why all this complicatedness?

sh 'env'

does what you need (under *nix)

I'm using:

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        const string DEFAULT_NAMESPACE = "http://www.something.org/schema";
        var serializer = new XmlSerializer(typeof(Person), DEFAULT_NAMESPACE);
        var namespaces = new XmlSerializerNamespaces();
        namespaces.Add("", DEFAULT_NAMESPACE);

        using (var stream = new MemoryStream())
        {
            var someone = new Person
            {
                FirstName = "Donald",
                LastName = "Duck"
            };
            serializer.Serialize(stream, someone, namespaces);
            stream.Position = 0;
            using (var reader = new StreamReader(stream))
            {
                Console.WriteLine(reader.ReadToEnd());
            }
        }
    }
}

To get the following XML:

<?xml version="1.0"?>
<Person xmlns="http://www.something.org/schema">
  <FirstName>Donald</FirstName>
  <LastName>Duck</LastName>
</Person>

If you don't want the namespace, just set DEFAULT_NAMESPACE to "".

A better way to normalize your image is to take each value and divide by the largest value experienced by the data type. This ensures that images that have a small dynamic range in your image remain small and they're not inadvertently normalized so that they become gray. For example, if your image had a dynamic range of [0-2], the code right now would scale that to have intensities of [0, 128, 255]. You want these to remain small after converting to np.uint8.

Therefore, divide every value by the largest value possible by the image type, not the actual image itself. You would then scale this by 255 to produced the normalized result. Use numpy.iinfo and provide it the type (dtype) of the image and you will obtain a structure of information for that type. You would then access the max field from this structure to determine the maximum value.

So with the above, do the following modifications to your code:

import numpy as np
import cv2
[...]
info = np.iinfo(data.dtype) # Get the information of the incoming image type
data = data.astype(np.float64) / info.max # normalize the data to 0 - 1
data = 255 * data # Now scale by 255
img = data.astype(np.uint8)
cv2.imshow("Window", img)

Note that I've additionally converted the image into np.float64 in case the incoming data type is not so and to maintain floating-point precision when doing the division.

The auto-completion with Jupyter Notebook is so weak, even with hinterland extension. Thanks for the idea of deep-learning-based code auto-completion. I developed a Jupyter Notebook Extension based on TabNine which provides code auto-completion based on Deep Learning. Here's the Github link of my work: jupyter-tabnine.

It's available on pypi index now. Simply issue following commands, then enjoy it:)

pip3 install jupyter-tabnine
jupyter nbextension install --py jupyter_tabnine
jupyter nbextension enable --py jupyter_tabnine
jupyter serverextension enable --py jupyter_tabnine

If anyone interested in the easiest example with ModelViewset for Django Rest Framework.

The Model is,

class MyModel(models.Model):
    name = models.CharField(db_column='name', max_length=200, blank=False, null=False, unique=True)
    imageUrl = models.FileField(db_column='image_url', blank=True, null=True, upload_to='images/')

    class Meta:
        managed = True
        db_table = 'MyModel'

The Serializer,

class MyModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = "__all__"

And the View is,

class MyModelView(viewsets.ModelViewSet):
    queryset = MyModel.objects.all()
    serializer_class = MyModelSerializer

Test in Postman,

To extend the example from @robbie-hanson ...

static MySingleton* sharedSingleton = nil;

+ (void)initialize {
    static BOOL initialized = NO;
    if (!initialized) {
        initialized = YES;
        sharedSingleton = [[self alloc] init];
    }
}

- (id)init {
    self = [super init];
    if (self) {
        // Member initialization here.
    }
    return self;
}

There is another way to draw a circle - draw it in fragment shader. Create a quad:

float right = 0.5;
float bottom = -0.5;
float left = -0.5;
float top = 0.5;
float quad[20] = {
    //x, y, z, lx, ly
    right, bottom, 0, 1.0, -1.0,
    right, top, 0, 1.0, 1.0,
    left, top, 0, -1.0, 1.0,
    left, bottom, 0, -1.0, -1.0,
};

Bind VBO:

unsigned int glBuffer;
glGenBuffers(1, &glBuffer);
glBindBuffer(GL_ARRAY_BUFFER, glBuffer);
glBufferData(GL_ARRAY_BUFFER, sizeof(float)*20, quad, GL_STATIC_DRAW);

and draw:

#define BUFFER_OFFSET(i) ((char *)NULL + (i))
glEnableVertexAttribArray(ATTRIB_VERTEX);
glEnableVertexAttribArray(ATTRIB_VALUE);
glVertexAttribPointer(ATTRIB_VERTEX , 3, GL_FLOAT, GL_FALSE, 20, 0);
glVertexAttribPointer(ATTRIB_VALUE , 2, GL_FLOAT, GL_FALSE, 20, BUFFER_OFFSET(12));
glDrawArrays(GL_TRIANGLE_FAN, 0, 4);

Vertex shader

attribute vec2 value;
uniform mat4 viewMatrix;
uniform mat4 projectionMatrix;
varying vec2 val;
void main() {
    val = value;
    gl_Position = projectionMatrix*viewMatrix*vertex;
}

Fragment shader

varying vec2 val;
void main() {
    float R = 1.0;
    float R2 = 0.5;
    float dist = sqrt(dot(val,val));
    if (dist >= R || dist <= R2) {
        discard;
    }
    float sm = smoothstep(R,R-0.01,dist);
    float sm2 = smoothstep(R2,R2+0.01,dist);
    float alpha = sm*sm2;
    gl_FragColor = vec4(0.0, 0.0, 1.0, alpha);
}

Don't forget to enable alpha blending:

glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA);

While all of the above links have merit, and have benefited me greatly in the past, as a linguist "exposed" to various Lucene search engines for the last 15 years, I have to say that elastic-search development is very fast in Python. That being said, some of the code felt non-intuitive to me. So, I reached out to one component of the ELK stack, Kibana, from an open source perspective, and found that I could generate the somewhat cryptic code of elasticsearch very easily in Kibana. Also, I could pull Chrome Sense es queries into Kibana as well. If you use Kibana to evaluate es, it will further speed up your evaluation. What took hours to run on other platforms was up and running in JSON in Sense on top of elasticsearch (RESTful interface) in a few minutes at worst (largest data sets); in seconds at best. The documentation for elasticsearch, while 700+ pages, didn't answer questions I had that normally would be resolved in SOLR or other Lucene documentation, which obviously took more time to analyze. Also, you may want to take a look at Aggregates in elastic-search, which have taken Faceting to a new level.

Bigger picture: if you're doing data science, text analytics, or computational linguistics, elasticsearch has some ranking algorithms that seem to innovate well in the information retrieval area. If you're using any TF/IDF algorithms, Text Frequency/Inverse Document Frequency, elasticsearch extends this 1960's algorithm to a new level, even using BM25, Best Match 25, and other Relevancy Ranking algorithms. So, if you are scoring or ranking words, phrases or sentences, elasticsearch does this scoring on the fly, without the large overhead of other data analytics approaches that take hours--another elasticsearch time savings. With es, combining some of the strengths of bucketing from aggregations with the real-time JSON data relevancy scoring and ranking, you could find a winning combination, depending on either your agile (stories) or architectural(use cases) approach.

Note: did see a similar discussion on aggregations above, but not on aggregations and relevancy scoring--my apology for any overlap. Disclosure: I don't work for elastic and won't be able to benefit in the near future from their excellent work due to a different architecural path, unless I do some charity work with elasticsearch, which wouldn't be a bad idea

If you do know the maximal length of a line, you can do

def getLastLine(fname, maxLineLength=80):
    fp=file(fname, "rb")
    fp.seek(-maxLineLength-1, 2) # 2 means "from the end of the file"
    return fp.readlines()[-1]

This works on my windows machine. But I do not know what happens on other platforms if you open a text file in binary mode. The binary mode is needed if you want to use seek().

If you are ok with manually selecting the column, you could be very fast using pick:

svn st | pick | xargs rm

Just go to any cell of the 2nd column, press c and then hit enter

You can use .on() to bind a function to multiple events:

$('#element').on('keyup keypress blur change', function(e) {
    // e.type is the type of event fired
});

Or just pass the function as the parameter to normal event functions:

var myFunction = function() {
   ...
}

$('#element')
    .keyup(myFunction)
    .keypress(myFunction)
    .blur(myFunction)
    .change(myFunction)

There are many ways to skip the first line. In addition to those said by Bakuriu, I would add:

with open(filename, 'r') as f:
    next(f)
    for line in f:

and:

with open(filename,'r') as f:
    lines = f.readlines()[1:]

you don't need define positioning when you need vertical align center for inline and block elements you can take mentioned below idea:-

inline-elements :- <img style="vertical-align:middle" ...>
                   <span style="display:inline-block; vertical-align:middle"> foo<br>bar </span>  

block-elements :- <td style="vertical-align:middle"> ... </td>
                  <div style="display:table-cell; vertical-align:middle"> ... </div>

see the demo:- http://jsfiddle.net/Ewfkk/2/

Just like normal background-color: #f0f

You just need a way to target it, eg: <option id="myPinkOption">blah</option>

I tried the solution below, it works on my machine.

<context:property-placeholder location="classpath*:connection.properties" ignore-unresolvable="true" order="1" />

<context:property-placeholder location="classpath*:general.properties" order="2"/>

In case multiple elements are present in the Spring context, there are a few best practices that should be followed:

the order attribute needs to be specified to fix the order in which these are processed by Spring all property placeholders minus the last one (highest order) should have ignore-unresolvable=”true” to allow the resolution mechanism to pass to others in the context without throwing an exception

There's no catchall function, because there are multiple concerns to be addressed.

1. SQL Injection - Today, generally, every PHP project should be using prepared statements via PHP Data Objects (PDO) as a best practice, preventing an error from a stray quote as well as a full-featured solution against injection. It's also the most flexible & secure way to access your database.

   Check out (The only proper) PDO tutorial for pretty much everything you need to know about PDO. (Sincere thanks to top SO contributor, @YourCommonSense, for this great resource on the subject.)

2. XSS - Sanitize data on the way in...

   • HTML Purifier has been around a long time and is still actively updated. You can use it to sanitize malicious input, while still allowing a generous & configurable whitelist of tags. Works great with many WYSIWYG editors, but it might be heavy for some use cases.

   • In other instances, where we don't want to accept HTML/Javascript at all, I've found this simple function useful (and has passed multiple audits against XSS):

     /* Prevent XSS input */ function sanitizeXSS () { $_GET = filter_input_array(INPUT_GET, FILTER_SANITIZE_STRING); $_POST = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING); $_REQUEST = (array)$_POST + (array)$_GET + (array)$_REQUEST; }

3. XSS - Sanitize data on the way out... unless you guarantee the data was properly sanitized before you add it to your database, you'll need to sanitize it before displaying it to your user, we can leverage these useful PHP functions:

   • When you call echo or print to display user-supplied values, use htmlspecialchars unless the data was properly sanitized safe and is allowed to display HTML.
   • json_encode is a safe way to provide user-supplied values from PHP to Javascript

4. Do you call external shell commands using exec() or system() functions, or to the backtick operator? If so, in addition to SQL Injection & XSS you might have an additional concern to address, users running malicious commands on your server. You need to use escapeshellcmd if you'd like to escape the entire command OR escapeshellarg to escape individual arguments.

In class WeatherRecord:

First import the class if they are in different package else this statement is not requires

Import <path>.ClassName

Then, just referene or call your object like:

Date d;
TempratureRange tr;
d = new Date();
tr = new TempratureRange;
//this can be done in Single Line also like :
// Date d = new Date();

But in your code you are not required to create an object to call function of Date and TempratureRange. As both of the Classes contain Static Function , you cannot call the thoes function by creating object.

Date.date(date,month,year);   // this is enough to call those static function

"Failed to show response data" can also happen if you are doing crossdomain requests and the remote host is not properly handling the CORS headers. Check your js console for errors.

Try C# 7.0

var Dob= DateTime.TryParseExact(s: YourDateString,format: "yyyyMMdd",provider: null,style: 0,out var dt)
 ? dt : DateTime.Parse("1800-01-01");

app.component.html

<div>
     <h5 style="color:#ffffff;">{{myDate | date:'fullDate'}}</h5>
</div>

app.component.ts

export class AppComponent implements OnInit {
myDate = Date.now();    //date 

I have the problem anyway with -lm added

gcc -Wall -lm mtest.c -o mtest.o
mtest.c: In function 'f1':
mtest.c:6:12: warning: unused variable 'res' [-Wunused-variable]
/tmp/cc925Nmf.o: In function `f1':
mtest.c:(.text+0x19): undefined reference to `sin'
collect2: ld returned 1 exit status

I discovered recently that it does not work if you first specify -lm. The order matters:

gcc mtest.c -o mtest.o -lm

Just link without problems

So you must specify the libraries after.

You can use below IsValidDate():

 public static bool IsValidDate(string value, string[] dateFormats)
    {
        DateTime tempDate;
        bool validDate = DateTime.TryParseExact(value, dateFormats, DateTimeFormatInfo.InvariantInfo, DateTimeStyles.None, ref tempDate);
        if (validDate)
            return true;
        else
            return false;
    }

And you can pass in the value and date formats. For example:

var data = "02-08-2019";
var dateFormats = {"dd.MM.yyyy", "dd-MM-yyyy", "dd/MM/yyyy"}

if (IsValidDate(data, dateFormats))
{
    //Do something
}
else
{
    //Do something else
}

The answers to your two questions are related. I'll start with the second:

Once you have staged a file (often with git add, though some other commands implicitly stage the changes as well, like git rm) you can back out that change with git reset -- <file>.

In your case you must have used git rm to remove the file, which is equivalent to simply removing it with rm and then staging that change. If you first unstage it with git reset -- <file> you can then recover it with git checkout -- <file>.

exDict = {1:1, 2:2, 3:3}
with open('file.txt', 'w+') as file:
    file.write(str(exDict))

Sadly, I think that JSTL doesn't support anything but an iteration through all elements to figure this out. In the past, I've used the forEach method in the core tag library:

<c:set var="contains" value="false" />
<c:forEach var="item" items="${myList}">
  <c:if test="${item eq myValue}">
    <c:set var="contains" value="true" />
  </c:if>
</c:forEach>

After this runs, ${contains} will be equal to "true" if myList contained myValue.

I use div by adding contenteditable true instead of using textarea.

Hope can help you.

$("#your_textarea").on('keydown', function(e){//textarea keydown events
  if(e.key == "Enter")
  {
    if(e.shiftKey)//jump new line
    {
     // do nothing
    }
    else  // do sth,like send message or else
    {
       e.preventDefault();//cancell the deafult events
    }
  }
})

db.<COLLECTION NAME>.find({ "<FIELD NAME>": { $exists: true, $ne: null } })

This error can also show up if there are parts in your string that json.loads() does not recognize. An in this example string, an error will be raised at character 27 (char 27).

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

My solution to this would be to use the string.replace() to convert these items to a string:

import json

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

string = string.replace("False", '"False"')

dict_list = json.loads(string)

Was able to solve this problem in my asp.net mvc project by updating my version of Newton.Json (old Version = 9.0.0.0 to new Version 11.0.0.0) usign Package Manager.

As for me, I realized there was another web project in the solution that my VS2017 was loading fine, so I copied over the ProjectTypeGuids element of it over to the project that wasn't loading. Its diff was:

-    <ProjectTypeGuids>{E3E379DF-F4C6-4180-9B81-6769533ABE47};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
+    <ProjectTypeGuids>{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>

After this, it loads. Don't ask me why.

When you have a function that can receive pointers to more than one type, calling it with NULL is ambiguous. The way this is worked around now is very hacky by accepting an int and assuming it's NULL.

template <class T>
class ptr {
    T* p_;
    public:
        ptr(T* p) : p_(p) {}

        template <class U>
        ptr(U* u) : p_(dynamic_cast<T*>(u)) { }

        // Without this ptr<T> p(NULL) would be ambiguous
        ptr(int null) : p_(NULL)  { assert(null == NULL); }
};

In C++11 you would be able to overload on nullptr_t so that ptr<T> p(42); would be a compile-time error rather than a run-time assert.

ptr(std::nullptr_t) : p_(nullptr)  {  }

To make height:100% work for the inner div, you have to set a height for the parent td. For my particular case it worked using height:100%. This made the inner div height stretch, while the other elements of the table didn't allow the td to become too big. You can of course use other values than 100%

If you want to also make the table cell have a fixed height so that it does not get bigger based on content (to make the inner div scroll or hide overflow), that is when you have no choice but do some js tricks. The parent td will need to have the height specified in a non relative unit (not %). And you will most probably have no choice but to calculate that height using js. This would also need the table-layout:fixed style set for the table element

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

In case if anyone wants to grab only the Time from a ISO Date, following will be helpful. I was searching for that and I couldn't find a question for it. So in case some one sees will be helpful.

let isoDate = '2020-09-28T15:27:15+05:30';
let result = isoDate.match(/\d\d:\d\d/);
console.log(result[0]);

The output will be the only the time from isoDate which is,

15:27

Option 1 allows you to initialize const members. This cannot be done with option 2 (as they are assigned to, not initialized).

Why must const members be intialized in the constructor initializer rather than in its body?

Save a copy of your spreadsheet first (just in case).

1. Insert two new columns to the left of the numbered column.

2. Put a k in the first row of the first (new) column.

3. Copy it (the k).

4. Go to the original first column (now the third column) and leave your cursor on the first row that has data.

5. Hit ctrl and down arrow (at the same time) to jump to the bottom of the populated data range for your original first column.

6. Left arrow twice to get to the new first column, the one with a k at the very top.

7. Hit Ctrl-shift-up arrow to go to the first cell with data populated (the original k you put in), highlighting all the cells in-between your starting and ending point.

8. Use paste (ctrl-v, right-click or whatever your preferred method), and it'll fill all those cells with a k.

9. Then use the "Concatenate" formula in the second column. Its two arguments will be the column of Ks (column A, first column) and the column with the numbers in it.

10. This will get you a column with the results of the K column and your numbers.

Hope this helps! The ctrl-shift-arrow and ctrl-arrow shortcuts are amazing for working with large datasets in Excel.

You can free memory used by vector by this way:

//Removes all elements in vector
v.clear()

//Frees the memory which is not used by the vector
v.shrink_to_fit();

The answers already explain how attributes and properties are handled differently, but I really would like to point out how totally insane this is. Even if it is to some extent the spec.

It is crazy, to have some of the attributes (e.g. id, class, foo, bar) to retain only one kind of value in the DOM, while some attributes (e.g. checked, selected) to retain two values; that is, the value "when it was loaded" and the value of the "dynamic state". (Isn't the DOM supposed to be to represent the state of the document to its full extent?)

It is absolutely essential, that two input fields, e.g. a text and a checkbox behave the very same way. If the text input field does not retain a separate "when it was loaded" value and the "current, dynamic" value, why does the checkbox? If the checkbox does have two values for the checked attribute, why does it not have two for its class and id attributes? If you expect to change the value of a text *input* field, and you expect the DOM (i.e. the "serialized representation") to change, and reflect this change, why on earth would you not expect the same from an input field of type checkbox on the checked attribute?

The differentiation, of "it is a boolean attribute" just does not make any sense to me, or is, at least not a sufficient reason for this.

parseInt((new Date('2012.08.10').getTime() / 1000).toFixed(0))

It's important to add the toFixed(0) to remove any decimals when dividing by 1000 to convert from milliseconds to seconds.

The .getTime() function returns the timestamp in milliseconds, but true unix timestamps are always in seconds.

Note that the answers that suggest using unbind() are now out of date as that method has been deprecated and will be removed in future versions of jQuery.

As of jQuery 3.0, .unbind() has been deprecated. It was superseded by the .off() method since jQuery 1.7, so its use was already discouraged.

Instead, you should now use off():

$(window).off('scroll');

You can use the module called win32clipboard, which is part of pywin32.

Here is an example that first sets the clipboard data then gets it:

import win32clipboard

# set clipboard data
win32clipboard.OpenClipboard()
win32clipboard.EmptyClipboard()
win32clipboard.SetClipboardText('testing 123')
win32clipboard.CloseClipboard()

# get clipboard data
win32clipboard.OpenClipboard()
data = win32clipboard.GetClipboardData()
win32clipboard.CloseClipboard()
print data

An important reminder from the documentation:

When the window has finished examining or changing the clipboard, close the clipboard by calling CloseClipboard. This enables other windows to access the clipboard. Do not place an object on the clipboard after calling CloseClipboard.

Darin Dimitrov's answer shows that OrderBy is slightly faster than List.Sort when faced with already-sorted input. I modified his code so it repeatedly sorts the unsorted data, and OrderBy is in most cases slightly slower.

Furthermore, the OrderBy test uses ToArray to force enumeration of the Linq enumerator, but that obviously returns a type (Person[]) which is different from the input type (List<Person>). I therefore re-ran the test using ToList rather than ToArray and got an even bigger difference:

Sort: 25175ms
OrderBy: 30259ms
OrderByWithToList: 31458ms

In some cases you should use:

req.path

This gives you the path, instead of the complete requested URL. For example, if you are only interested in which page the user requested and not all kinds of parameters the url:

/myurl.htm?allkinds&ofparameters=true

req.path will give you:

/myurl.html

Range("A1").value = Environ("Username")

This is better than Application.Username, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.

• Application Username is the name of the User set in Excel > Tools > Options
• Environ("Username") is the name you registered for Windows; see Control Panel >System

With the window.location object. This code gives you GET without the question mark.

window.location.search.substr(1)

From your example it will return returnurl=%2Fadmin

EDIT: I took the liberty of changing Qwerty's answer, which is really good, and as he pointed I followed exactly what the OP asked:

function findGetParameter(parameterName) {
    var result = null,
        tmp = [];
    location.search
        .substr(1)
        .split("&")
        .forEach(function (item) {
          tmp = item.split("=");
          if (tmp[0] === parameterName) result = decodeURIComponent(tmp[1]);
        });
    return result;
}

I removed the duplicated function execution from his code, replacing it a variable ( tmp ) and also I've added decodeURIComponent, exactly as OP asked. I'm not sure if this may or may not be a security issue.

Or otherwise with plain for loop, which will work even in IE8:

function findGetParameter(parameterName) {
    var result = null,
        tmp = [];
    var items = location.search.substr(1).split("&");
    for (var index = 0; index < items.length; index++) {
        tmp = items[index].split("=");
        if (tmp[0] === parameterName) result = decodeURIComponent(tmp[1]);
    }
    return result;
}

You may use the different accessors to communicate your intent to someone reading your code, and make it easier to write classes which will work correctly no matter how their public API is called.

class Person
  attr_accessor :age
  ...
end

Here, I can see that I may both read and write the age.

class Person
  attr_reader :age
  ...
end

Here, I can see that I may only read the age. Imagine that it is set by the constructor of this class and after that remains constant. If there were a mutator (writer) for age and the class were written assuming that age, once set, does not change, then a bug could result from code calling that mutator.

But what is happening behind the scenes?

If you write:

attr_writer :age

That gets translated into:

def age=(value)
  @age = value
end

If you write:

attr_reader :age

That gets translated into:

def age
  @age
end

If you write:

attr_accessor :age

That gets translated into:

def age=(value)
  @age = value
end

def age
  @age
end

Knowing that, here's another way to think about it: If you did not have the attr_... helpers, and had to write the accessors yourself, would you write any more accessors than your class needed? For example, if age only needed to be read, would you also write a method allowing it to be written?

#include works just like the C #include.

#import keeps track of which headers have already been included and is ignored if a header is imported more than once in a compilation unit. This makes it unnecessary to use header guards.

The bottom line is just use #import in Objective-C and don't worry if your headers wind up importing something more than once.

Here are 3 different methods to check this

<?php
//Method 1
if(!empty($_GET))
echo "exist";
else
echo "do not exist";
//Method 2
echo "<br>";
if($_GET)
echo "exist";
else
echo "do not exist";
//Method 3
if(count($_GET))
echo "exist";
else
echo "do not exist";
?>

Or as a single command:

git push -u origin master:my_test

Pushes the commits from your local master branch to a (possibly new) remote branch my_test and sets up master to track origin/my_test.

The above programs might give you NullPointerException. This is an easier way to add an element to the end of linkedList.

public class LinkedList {
    Node head;

    public static class Node{
        int data;
        Node next;

        Node(int item){
            data = item;
            next = null;
        }
    }
    public static void main(String args[]){
        LinkedList ll = new LinkedList();
        ll.head = new Node(1);
        Node second = new Node(2);
        Node third = new Node(3);
        Node fourth = new Node(4);

        ll.head.next = second;
        second.next = third;
        third.next = fourth;
        fourth.next = null;

        ll.printList();
        System.out.println("Add element 100 to the last");
        ll.addLast(100);
        ll.printList();
    }
    public void printList(){
        Node t = head;
        while(n != null){
            System.out.println(t.data);
            t = t.next;
        }

    }

    public void addLast(int item){
        Node new_item = new Node(item);
        if(head == null){
            head = new_item;
            return;
        }
        new_item.next = null;

        Node last = head;
        Node temp = null;
        while(last != null){
            if(last != null)
                temp = last;
            last = last.next;
        }   

        temp.next = new_item;   
        return;
    }
}

Let tell you a simple formula to find xpath of any element:

1- Open site in browser

2- Select element and right click on it

3- Click inspect element option

4- Right click on selected html

5- choose option to copy xpath Use it where ever you need it

This video link will be helpful for you. http://screencast.com/t/afXsaQXru

Note: For advance options of xpath you must know regex or pattern of your html.

One option is to type [command] + [shift] + [p] (or the equivalent) and then type 'indentation'. The top result should be 'Indendtation: Reindent Lines'. Press [enter] and it will format the document.

Another option is to install the Emmet plugin (http://emmet.io/), which will provide not only better formatting, but also a myriad of other incredible features. To get the output you're looking for using Sublime Text 3 with the Emmet plugin requires just the following:

p [tab][enter] Hello world!

When you type p [tab] Emmet expands it to:

<p></p>

Pressing [enter] then further expands it to:

<p>

</p>

With the cursor indented and on the line between the tags. Meaning that typing text results in:

<p>
    Hello, world!
</p>

You can simply do this with a bool:

if int(number) == float(number):

   number = int(number)

else:

   number = float(number)

Similar to @radiak's response, but with jQuery (see this API document and comment on how to change the selectedIndex).

$('#mySelectParent').find("select").prop("selectedIndex",-1);

The benefits to this approach are:

• You can stay within jQuery
• You can limit the scope using jQuery selectors (#mySelectParent in the example)
• More explicitly defined code
• Works in IE8, Chrome, FF

What I can quickly think of is, generate the pdf and store it in webapp/downloads/< RANDOM-FILENAME>.pdf from the code and send a forward to this file using HttpServletRequest

request.getRequestDispatcher("/downloads/<RANDOM-FILENAME>.pdf").forward(request, response);

or if you can configure your view resolver something like,

  <bean id="pdfViewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass"
              value="org.springframework.web.servlet.view.JstlView" />
    <property name="order" value=”2"/>
    <property name="prefix" value="/downloads/" />
    <property name="suffix" value=".pdf" />
  </bean>

then just return

return "RANDOM-FILENAME";

see here

The consumable media types of the mapped request, narrowing the primary mapping.

the producer is used to narrow the primary mapping, you send request should specify the exact header to match it.

This code handled every input for me in the whole site. It checks for the ENTER KEY inside an INPUT field and doesn't stop on TEXTAREA or other places.

$(document).on("keydown", "input", function(e){
 if(e.which == 13){
  event.preventDefault();
  return false;
 }
});

Thanks all person who try to help in this post

I have ubuntu 13.10 and my chrome version is 34.0

For my situation this works

1.open developer tools in chrome(or use right click on your page and then select inspect element)
2.go to "Network" tab
3.find your ajax request in "Name Path" column 
4.click on the specific ajax link

now you should see a new Panel in front of you request

in this panel select "Response" tab

Instantiate a new ArrayList:

List<String> myList = new ArrayList<String>();

Iterate over your data structure (with a for loop, for instance, more details on your code would help.) and for each element (yourElement):

myList.add(yourElement);

In reply to Is there a specific reason?, here is one interesting application: breaking out of multiple levels of looping.

Here is how it works: the outer loop has a break at the end, so it would only be executed once. However, if the inner loop completes (finds no divisor), then it reaches the else statement and the outer break is never reached. This way, a break in the inner loop will break out of both loops, rather than just one.

for k in [2, 3, 5, 7, 11, 13, 17, 25]:
    for m in range(2, 10):
        if k == m:
            continue
        print 'trying %s %% %s' % (k, m)
        if k % m == 0:
            print 'found a divisor: %d %% %d; breaking out of loop' % (k, m)
            break
    else:
        continue
    print 'breaking another level of loop'
    break
else:
    print 'no divisor could be found!'

For both while and for loops, the else statement is executed at the end, unless break was used.

In most cases there are better ways to do this (wrapping it into a function or raising an exception), but this works!

List<string> empnames = emplist.Select(e => e.Ename).ToList();

This is an example of Projection in Linq. Followed by a ToList to resolve the IEnumerable<string> into a List<string>.

Alternatively in Linq syntax (head compiled):

var empnamesEnum = from emp in emplist 
                   select emp.Ename;
List<string> empnames = empnamesEnum.ToList();

Projection is basically representing the current type of the enumerable as a new type. You can project to anonymous types, another known type by calling constructors etc, or an enumerable of one of the properties (as in your case).

For example, you can project an enumerable of Employee to an enumerable of Tuple<int, string> like so:

var tuples = emplist.Select(e => new Tuple<int, string>(e.EID, e.Ename));

What about this. Seems to give better performance.

byte[] bytes = new byte[1000];

StringBuilder x = new StringBuilder();

int numRead = 0;
while ((numRead = is.read(bytes)) >= 0) {
    x.append(new String(bytes, 0, numRead));
}

Edit: Actually this sort of encompasses both steelbytes and Maurice Perry's

I am asking in general, how to write a compatible awk script that performs the same functionality ...

To solve the problem in your quesiton is easy. (check others' answer).

If you want to write an awk script, which portable to any awk implementations and versions (gawk/nawk/mawk...) it is really hard, even if with --posix (gawk)

for example:

• some awk works on string in terms of characters, some with bytes
• some supports \x escape, some not
• FS interpreter works differently
• keywords/reserved words abbreviation restriction
• some operator restriction e.g. **
• even same awk impl. (gawk for example), the version 4.0 and 3.x have difference too.
• the implementation of certain functions are also different. (your problem is one example, see below)

well all the points above are just spoken in general. Back to your problem, you problem is only related to fundamental feature of awk. awk '{print $x}' the line like that will work all awks.

There are two reasons why your awk line behaves differently on gawk and mawk:

• your used substr() function wrongly. this is the main cause. you have substr($0, 0, RSTART - 1) the 0 should be 1, no matter which awk do you use. awk array, string idx etc are 1-based.

• gawk and mawk implemented substr() differently.

VS 2012 applications cannot be run under Windows XP.

See this VC++ blog on why and how to make it work.

It seems to be supported/possible from Feb 2013. See noelicus answer below on how to.

Let's suppose you have two different classes:

public class Person
{
    public string Name, Email;
    
    public Person(string name, string email)
    {
        Name = name;
        Email = email;
    }
}

class Data
{
    public string Mail, SlackId;
    
    public Data(string mail, string slackId)
    {
        Mail = mail;
        SlackId = slackId;
    }
}

Now, let's Prepare data to work with:

var people = new Person[]
    {
        new Person("Sudi", "[email protected]"),
        new Person("Simba", "[email protected]"),
        new Person("Sarah", string.Empty)
    };
    
    var records = new Data[]
    {
        new Data("[email protected]", "Sudi_Try"),
        new Data("[email protected]", "Sudi@Test"),
        new Data("[email protected]", "SimbaLion")
    };

You will note that [email protected] has got two slackIds. I have made that for demonstrating how Join works.

Let's now construct the query to join Person with Data:

var query = people.Join(records,
        x => x.Email,
        y => y.Mail,
        (person, record) => new { Name = person.Name, SlackId = record.SlackId});
    Console.WriteLine(query);

After constructing the query, you could also iterate over it with a foreach like so:

foreach (var item in query)
    {
        Console.WriteLine($"{item.Name} has Slack ID {item.SlackId}");
    }

Let's also output the result for GroupJoin:

Console.WriteLine(
    
        people.GroupJoin(
            records,
            x => x.Email,
            y => y.Mail,
            (person, recs) => new {
                Name = person.Name,
                SlackIds = recs.Select(r => r.SlackId).ToArray() // You could materialize //whatever way you want.
            }
        ));

You will notice that the GroupJoin will put all SlackIds in a single group.

How to detect iOS device models and screen size?

CheckDevice is detected the current ? device model and screen sizes.

You can also use

CheckDevice.size() returned for iPhone 12 mini's .screen5_4Inch

etc... maybe...

CheckDevice.isPhone()

to check the device type iPhone.

CheckDevice.isWatch()

CheckDevice.isSimulator()

CheckDevice.isPad()

Even if the += operator is now permitted, it has been introduced in Bash 3.1 in 2004.

Any script using this operator on older Bash versions will fail with a "command not found" error if you are lucky, or a "syntax error near unexpected token".

For those who cares about backward compatibility, stick with the older standard Bash concatenation methods, like those mentioned in the chosen answer:

foo="Hello"
foo="$foo World"
echo $foo
> Hello World

This resolves it for me:

Go to (C:\users\%USERNAME%\AppData\Local\Android\sdk, generally).

Then go to Extras -> Intel -> Hardware_Accelerated_Execution_Manager and run the file named "intelhaxm-android.exe".

In case you get an error like "Intel virtualization technology (vt,vt-x) is not enabled", go to your BIOS settings and enable Hardware Virtualization.

Restart your studio

It is the same construct - simply test for empty strings rather than NA:

Try this:

df <- df[-which(df$start_pc == ""), ]

In fact, looking at your code, you don't need the which, but use the negation instead, so you can simplify it to:

df <- df[!(df$start_pc == ""), ]
df <- df[!is.na(df$start_pc), ]

And, of course, you can combine these two statements as follows:

df <- df[!(df$start_pc == "" | is.na(df$start_pc)), ]

And simplify it even further with with:

df <- with(df, df[!(start_pc == "" | is.na(start_pc)), ])

You can also test for non-zero string length using nzchar.

df <- with(df, df[!(nzchar(start_pc) | is.na(start_pc)), ])

Disclaimer: I didn't test any of this code. Please let me know if there are syntax errors anywhere

In case anyone else ends up as lost as I was... My issues were NOT due to CORS (I have full control of the server(s) and CORS was configured correctly!).

My issue was because I am using Android platform level 28 which disables cleartext network communications by default and I was trying to develop the app which points at my laptop's IP (which is running the API server). The API base URL is something like http://[LAPTOP_IP]:8081. Since it's not https, android webview completely blocks the network xfer between the phone/emulator and the server on my laptop. In order to fix this:

Add a network security config

New file in project: resources/android/xml/network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
  <!-- Set application-wide security config -->
  <base-config cleartextTrafficPermitted="true"/>
</network-security-config>

NOTE: This should be used carefully as it will allow all cleartext from your app (nothing forced to use https). You can restrict it further if you wish.

Reference the config in main config.xml

<platform name="android">
    ...
    <edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application" xmlns:android="http://schemas.android.com/apk/res/android">
        <application android:networkSecurityConfig="@xml/network_security_config" />
    </edit-config>
    <resource-file src="resources/android/xml/network_security_config.xml" target="app/src/main/res/xml/network_security_config.xml" />
    ....
</platform>

That's it! From there I rebuilt the APK and the app was now able to communicate from both the emulator and phone.

Before your write to Excel need to change the format:

xlApp = New Excel.Application
xlWorkSheet = xlWorkBook.Sheets("Sheet1")

Dim cells As Excel.Range = xlWorkSheet.Cells

'set each cell's format to Text
cells.NumberFormat = "@"

'reset horizontal alignment to the right
cells.HorizontalAlignment = Excel.XlHAlign.xlHAlignRight

public class B3PassingExcelDataBase {


    @Test()
    //Import the data::row start at 3 and column at 1: 
    public static void imortingData () throws IOException {

        FileInputStream  file=new         FileInputStream("/Users/Downloads/Book2.xlsx");
        XSSFWorkbook book=new XSSFWorkbook(file);
        XSSFSheet sheet=book.getSheet("Sheet1");

        int rowNum=sheet.getLastRowNum();
        System.out.println(rowNum);

        //get the row and value and assigned to variable to use in application
        for (int r=3;r<rowNum;r++) {

            // Rows stays same but column num changes and this is for only one person. It iterate for other.
             XSSFRow currentRow=sheet.getRow(r);

             String fName=currentRow.getCell(1).toString();
             String lName=currentRow.getCell(2).toString();
             String phone=currentRow.getCell(3).toString();
             String email=currentRow.getCell(4).toString()

               //passing the data
                yogen.findElement(By.name("firstName")).sendKeys(fName);    ;
                yogen.findElement(By.name("lastName")).sendKeys(lName); ;
                yogen.findElement(By.name("phone")).sendKeys(phone);    ;

        }

        yogen.close();


    }

}

If the data is not null-terminated, you should use -initWithData:encoding:

NSString* newStr = [[NSString alloc] initWithData:theData encoding:NSUTF8StringEncoding];

If the data is null-terminated, you should instead use -stringWithUTF8String: to avoid the extra \0 at the end.

NSString* newStr = [NSString stringWithUTF8String:[theData bytes]];

(Note that if the input is not properly UTF-8-encoded, you will get nil.)

Swift variant:

let newStr = String(data: data, encoding: .utf8)
// note that `newStr` is a `String?`, not a `String`.

If the data is null-terminated, you could go though the safe way which is remove the that null character, or the unsafe way similar to the Objective-C version above.

// safe way, provided data is \0-terminated
let newStr1 = String(data: data.subdata(in: 0 ..< data.count - 1), encoding: .utf8)
// unsafe way, provided data is \0-terminated
let newStr2 = data.withUnsafeBytes(String.init(utf8String:))

You should do it in the xaml code:

<DataGrid ItemsSource="{Binding list}" [...]>
  [...]
</DataGrid>

I would advise you to use an ObservableCollection as your backing collection, as that would propagate changes to the datagrid, as it implements INotifyCollectionChanged.

Not Just HTML, Using atom-beautify - Package for Atom, you can format code for HTML, CSS, JavaScript, PHP, Python, Ruby, Java, C, C++, C#, Objective-C, CoffeeScript, TypeScript, Coldfusion, SQL, and more) in Atom within a matter of seconds.

To Install the atom-beautify package :

• Open Atom Editor.
• Press Ctrl+Shift+P (Cmd+Shift+P on mac), this will open the atom Command Palette.
• Search and click on Install Packages & Themes. A Install Package window comes up.
• Search for Beautify package, you will see a lot of beautify packages. Install any. I will recommend for atom-beautify.
• Now Restart atom and TADA! now you are ready for quick formatting.

To Format text Using atom-beautify :

• Go to the file you want to format.
• Hit Ctrl+Alt+B (Ctrl+Option+B on mac).
• Your file is formatted in seconds.

This worked for me.

jQuery('#grid').jqGrid('clearGridData');
jQuery('#grid').jqGrid('setGridParam', {data: dataToLoad});
jQuery('#grid').trigger('reloadGrid');

Here is a quick summary of the order characteristics of the standard Set implementations available in Java:

1. keep the insertion order: LinkedHashSet and CopyOnWriteArraySet (thread-safe)
2. keep the items sorted within the set: TreeSet, EnumSet (specific to enums) and ConcurrentSkipListSet (thread-safe)
3. does not keep the items in any specific order: HashSet (the one you tried)

For your specific case, you can either sort the items first and then use any of 1 or 2 (most likely LinkedHashSet or TreeSet). Or alternatively and more efficiently, you can just add unsorted data to a TreeSet which will take care of the sorting automatically for you.

While you use .on(), it's basically a live query that you are using.

On the other hand, .ready (as in your case) is a static query. While using it, you can dynamically update data and do not have to wait for the page to load. You can simply pass on the values into your database (if required) when a particular value is entered.

The use of live queries is common in forms where we enter data (account or posts or even comments).

I am answering the question - as I didn't find any of them complete. As nowadays Unknown character set: 'utf8mb4' is quite prevalent as lot of deployments have MySQL less then 5.5.3 (version in which utf8mb4 was added).

The error clearly states that you don't have utf8mb4 supported on your stage db server.

Cause: probably locally you have MySQL version 5.5.3 or greater, and on stage/hosted VPS you have MySQL server version less then 5.5.3

The utf8mb4 character sets was added in MySQL 5.5.3.

utf8mb4 was added because of a bug in MySQL's utf8 character set. MySQL's handling of the utf8 character set only allows a maximum of 3 bytes for a single codepoint, which isn't enough to represent the entirety of Unicode (Maximum codepoint = 0x10FFFF). Because they didn't want to potentially break any stuff that relied on this buggy behaviour, utf8mb4 was added. Documentation here.

From SO answer:

Verification: To verify you can check the current character set and collation for the DB you're importing the dump from - How do I see what character set a MySQL database / table / column is?

Solution 1: Simply upgrade your MySQL server to 5.5.3 (at-least) - for next time be conscious about the version you use locally, for stage, and for prod, all must have to be same. A suggestion - in present the default character set should be utf8mb4.

Solution 2 (not recommended): Convert the current character set to utf8, and then export the data - it'll load ok.

df['Name']='abc' will add the new column and set all rows to that value:

In [79]:

df
Out[79]:
         Date, Open, High,  Low,  Close
0  01-01-2015,  565,  600,  400,    450
In [80]:

df['Name'] = 'abc'
df
Out[80]:
         Date, Open, High,  Low,  Close Name
0  01-01-2015,  565,  600,  400,    450  abc

Expanding on Adis H's example to include the null case (got bit on this one)

 Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
            if (config.AppSettings.Settings["HostName"] != null)
                config.AppSettings.Settings["HostName"].Value = hostName;
            else                
                config.AppSettings.Settings.Add("HostName", hostName);                
            config.Save(ConfigurationSaveMode.Modified);
            ConfigurationManager.RefreshSection("appSettings");

The second one:

word.contains("\n");

First I think you need to fix your lists, as the first node of a <ul> must be a <li> (stackoverflow ref). Once that is setup you can do this:

// note this array has outer scope
var phrases = [];

$('.phrase').each(function(){
        // this is inner scope, in reference to the .phrase element
        var phrase = '';
        $(this).find('li').each(function(){
            // cache jquery var
            var current = $(this);
            // check if our current li has children (sub elements)
            // if it does, skip it
            // ps, you can work with this by seeing if the first child
            // is a UL with blank inside and odd your custom BLANK text
            if(current.children().size() > 0) {return true;}
            // add current text to our current phrase
            phrase += current.text();
        });
        // now that our current phrase is completely build we add it to our outer array
        phrases.push(phrase);
    });
    // note the comma in the alert shows separate phrases
    alert(phrases);

Working jsfiddle.

One thing is if you get the .text() of an upper level li you will get all sub level text with it.

Keeping an array will allow for many multiple phrases to be extracted.

EDIT:

This should work better with an empty UL with no LI:

// outer scope
var phrases = [];

$('.phrase').each(function(){
    // inner scope
    var phrase = '';
    $(this).find('li').each(function(){
        // cache jquery object
        var current = $(this);
        // check for sub levels
        if(current.children().size() > 0) {
            // check is sublevel is just empty UL
            var emptyULtest = current.children().eq(0); 
            if(emptyULtest.is('ul') && $.trim(emptyULtest.text())==""){
                phrase += ' -BLANK- '; //custom blank text
                return true;   
            } else {
             // else it is an actual sublevel with li's
             return true;   
            }
        }
        // if it gets to here it is actual li
        phrase += current.text();
    });
    phrases.push(phrase);
});
// note the comma to separate multiple phrases
alert(phrases);

only css, quite simple I find it:

.checkmark {_x000D_
      display: inline-block;_x000D_
      transform: rotate(45deg);_x000D_
      height: 25px;_x000D_
      width: 12px;_x000D_
      margin-left: 60%; _x000D_
      border-bottom: 7px solid #78b13f;_x000D_
      border-right: 7px solid #78b13f;_x000D_
    }

<div class="checkmark"></div>

Byterbit solution is problematic because:

1. having the client control expiration of a server side cookie is a security issue.
2. if expiration timeout set on server side is smaller than the timeout set on client side, the page would not reflect the actual state of the cookie.
3. even if for the sake of comfort in development stage, this is a problem because it won't reflect the right behaviour (in timing) on release stage.

for cookies, setting expiration via session.cookie_lifetime is the right solution design-wise and security-wise! for expiring the session, you can use session.gc_maxlifetime.

expiring the cookies by calling session_destroy might yield unpredictable results because they might have already been expired.

making the change in php.ini is also a valid solution but it makes the expiration global for the entire domain which might not be what you really want - some pages might choose to keep some cookies more than others.

I think it can help you:

CREATE PROCEDURE DEPT_COUNT
(
    @DEPT_NAME VARCHAR(20), -- Input parameter
    @D_COUNT INT OUTPUT     -- Output parameter
    -- Remember parameters begin with "@"
)
AS -- You miss this word in your example
BEGIN
    SELECT COUNT(*) 
    INTO #D_COUNT -- Into a Temp Table (prefix "#")
    FROM INSTRUCTOR
    WHERE INSTRUCTOR.DEPT_NAME = DEPT_COUNT.DEPT_NAME
END

Then, you can call the SP like this way, for example:

DECLARE @COUNTER INT
EXEC DEPT_COUNT 'DeptName', @COUNTER OUTPUT
SELECT @COUNTER

While JPA is the specification, Hibernate is the implementation provider that follows the rules dictated in the specification.

If you happen to be using jQuery, you might want to give this a shot: http://api.jquery.com/category/deferred-object/

It allows you to defer the execution of your callback function until the ajax request (or any async operation) is completed. This can also be used to call a callback once several ajax requests have all completed.

I have resolved it by deleting android-support-v4.jar from my Project. Because appcompat_v7 already have a copy of it.

If you have already import appcompat_v7 but still the problem doesn't solve. then try it.

To run a non-executable sh script, use:

sh myscript

To run a non-executable bash script, use:

bash myscript

To start an executable (which is any file with executable permission); you just specify it by its path:

/foo/bar
/bin/bar
./bar

To make a script executable, give it the necessary permission:

chmod +x bar
./bar

When a file is executable, the kernel is responsible for figuring out how to execte it. For non-binaries, this is done by looking at the first line of the file. It should contain a hashbang:

#! /usr/bin/env bash

The hashbang tells the kernel what program to run (in this case the command /usr/bin/env is ran with the argument bash). Then, the script is passed to the program (as second argument) along with all the arguments you gave the script as subsequent arguments.

That means every script that is executable should have a hashbang. If it doesn't, you're not telling the kernel what it is, and therefore the kernel doesn't know what program to use to interprete it. It could be bash, perl, python, sh, or something else. (In reality, the kernel will often use the user's default shell to interprete the file, which is very dangerous because it might not be the right interpreter at all or it might be able to parse some of it but with subtle behavioural differences such as is the case between sh and bash).

A note on /usr/bin/env

Most commonly, you'll see hash bangs like so:

#!/bin/bash

The result is that the kernel will run the program /bin/bash to interpret the script. Unfortunately, bash is not always shipped by default, and it is not always available in /bin. While on Linux machines it usually is, there are a range of other POSIX machines where bash ships in various locations, such as /usr/xpg/bin/bash or /usr/local/bin/bash.

To write a portable bash script, we can therefore not rely on hard-coding the location of the bash program. POSIX already has a mechanism for dealing with that: PATH. The idea is that you install your programs in one of the directories that are in PATH and the system should be able to find your program when you want to run it by name.

Sadly, you cannot just do this:

#!bash

The kernel won't (some might) do a PATH search for you. There is a program that can do a PATH search for you, though, it's called env. Luckily, nearly all systems have an env program installed in /usr/bin. So we start env using a hardcoded path, which then does a PATH search for bash and runs it so that it can interpret your script:

#!/usr/bin/env bash

This approach has one downside: According to POSIX, the hashbang can have one argument. In this case, we use bash as the argument to the env program. That means we have no space left to pass arguments to bash. So there's no way to convert something like #!/bin/bash -exu to this scheme. You'll have to put set -exu after the hashbang instead.

This approach also has another advantage: Some systems may ship with a /bin/bash, but the user may not like it, may find it's buggy or outdated, and may have installed his own bash somewhere else. This is often the case on OS X (Macs) where Apple ships an outdated /bin/bash and users install an up-to-date /usr/local/bin/bash using something like Homebrew. When you use the env approach which does a PATH search, you take the user's preference into account and use his preferred bash over the one his system shipped with.

I find this quite tricky, but there is some information on it here at the MatPlotLib FAQ. It is rather cumbersome, and requires finding out about what space individual elements (ticklabels) take up...

Update: The page states that the tight_layout() function is the easiest way to go, which attempts to automatically correct spacing.

Otherwise, it shows ways to acquire the sizes of various elements (eg. labels) so you can then correct the spacings/positions of your axes elements. Here is an example from the above FAQ page, which determines the width of a very wide y-axis label, and adjusts the axis width accordingly:

import matplotlib.pyplot as plt
import matplotlib.transforms as mtransforms
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(10))
ax.set_yticks((2,5,7))
labels = ax.set_yticklabels(('really, really, really', 'long', 'labels'))

def on_draw(event):
   bboxes = []
   for label in labels:
       bbox = label.get_window_extent()
       # the figure transform goes from relative coords->pixels and we
       # want the inverse of that
       bboxi = bbox.inverse_transformed(fig.transFigure)
       bboxes.append(bboxi)

   # this is the bbox that bounds all the bboxes, again in relative
   # figure coords
   bbox = mtransforms.Bbox.union(bboxes)
   if fig.subplotpars.left < bbox.width:
       # we need to move it over
       fig.subplots_adjust(left=1.1*bbox.width) # pad a little
       fig.canvas.draw()
   return False

fig.canvas.mpl_connect('draw_event', on_draw)

plt.show()

Just simply the css style using white-space:nowrap works very well to avoid text wrapping in cells. And ofcourse you can use the text-overflow:ellipsis and overflow:hidden for truncating text with ellipsis effect.

<td style="white-space:nowrap">Cell Value</td>

psql --pset=format=FORMAT

Great for executing queries from command line, e.g.

psql --pset=format=unaligned -c "select bandanavalue from bandana where bandanakey = 'atlassian.confluence.settings';"

Use a white space to match all descendants of an element:

div.dropdown * {
    color: red;
}

x y matches every element y that is inside x, however deeply nested it may be - children, grandchildren and so on.

The asterisk * matches any element.

you can use getopt to handle parameters in your bash script. there are not many explanations for getopt out there. here is an example:

#!/bin/sh

if [ $? -ne 0 ]; then
  echo "getopt error"
  exit 1
fi

eval set -- $OPTIONS

while true; do
  case "$1" in
    -h|--help) HELP=1 ;;
    -f|--file) FILE="$2" ; shift ;;
    -g|--foo)  FOO=1 ;;
    -b|--bar)  BAR=1 ;;
    --)        shift ; break ;;
    *)         echo "unknown option: $1" ; exit 1 ;;
  esac
  shift
done

if [ $# -ne 0 ]; then
  echo "unknown option(s): $@"
  exit 1
fi

echo "help: $HELP"
echo "file: $FILE"
echo "foo: $FOO"
echo "bar: $BAR"

I liked Eugen Mihailescu's solution to match the content between quotes whilst allowing to escape quotes. However, I discovered some problems with escaping and came up with the following regex to fix them:

(['"])(?:(?!\1|\\).|\\.)*\1

It does the trick and is still pretty simple and easy to maintain.

Demo (with some more test-cases; feel free to use it and expand on it).

_{PS: If you just want the content between quotes in the full match ($0), and are not afraid of the performance penalty use:}

(?<=(['"])\b)(?:(?!\1|\\).|\\.)*(?=\1)

_{Unfortunately, without the quotes as anchors, I had to add a boundary \b which does not play well with spaces and non-word boundary characters after the starting quote.}

_{Alternatively, modify the initial version by simply adding a group and extract the string form $2:}

(['"])((?:(?!\1|\\).|\\.)*)\1

_{PPS: If your focus is solely on efficiency, go with Casimir et Hippolyte's solution; it's a good one.}

See from How to Replace String in File works in a simple way and is an answer that works with replace

for line in fin:
    fout.write(line.replace('pyton', 'python'))

fin.close()
fout.close()

feel so stupid - (for whatever reason) i had one empty xml in drawable folder. and AS produced dozens of unrelated errors ><

so, my general advice would be the same - check briefly every resource file.

I forked, updated, refactored and mavenized the android-dateslider project. It is on Github now:

https://github.com/casidiablo/date-slider

Dim rows() AS DataRow = DataTable.Select("ColumnName1 = 'value3'")
If rows.Count > 0 Then
     searchedValue = rows(0).Item("ColumnName2") 
End If

With FirstOrDefault:

Dim row AS DataRow = DataTable.Select("ColumnName1 = 'value3'").FirstOrDefault()
If Not row Is Nothing Then
     searchedValue = row.Item("ColumnName2") 
End If

In C#:

var row = DataTable.Select("ColumnName1 = 'value3'").FirstOrDefault();
if (row != null)
     searchedValue = row["ColumnName2"];

Use the > command. To indent five lines, 5>>. To mark a block of lines and indent it, Vjj> to indent three lines (Vim only). To indent a curly-braces block, put your cursor on one of the curly braces and use >% or from anywhere inside block use >iB.

If you’re copying blocks of text around and need to align the indent of a block in its new location, use ]p instead of just p. This aligns the pasted block with the surrounding text.

Also, the shiftwidth setting allows you to control how many spaces to indent.

Regarding conventions in C#. Let's say you're reading a cell that contains a date, e.g. 2014-10-22.

When using:

.Text, you'll get the formatted representation of the date, as seen in the workbook on-screen:
2014-10-22. This property's type is always string but may not always return a satisfactory result.

.Value, the compiler attempts to convert the date into a DateTime object: {2014-10-22 00:00:00} Most probably only useful when reading dates.

.Value2, gives you the real, underlying value of the cell. In the case for dates, it's a date serial: 41934. This property can have a different type depending on the contents of the cell. For date serials though, the type is double.

So you can retrieve and store the value of a cell in either dynamic, var or object but note that the value will always have some sort of innate type that you will have to act upon.

dynamic x = ws.get_Range("A1").Value2;
object  y = ws.get_Range("A1").Value2;
var     z = ws.get_Range("A1").Value2;
double  d = ws.get_Range("A1").Value2;      // Value of a serial is always a double

Since MongoDB version 3.2 you can use updateMany():

> db.yourCollection.updateMany({}, {$set:{"someField": "someValue"}})

I had the same problem,

Set all text/varchar collations in phpMyAdmin to utf-8 and in php files add this:

mysql_set_charset("utf8", $your_connection_name);

This solved it for me.

md5=$(md5sum < index.html | head -c -4)

Spring 3 supports ${my.server.port:defaultValue} syntax.

I've submitted a pull request (available in Ansible 2.2+) that will make this kinds of situations easier by adding jmespath query support on Ansible. In your case it would work like:

- debug: msg="{{ addresses | json_query(\"private_man[?type=='fixed'].addr\") }}"

would return:

ok: [localhost] => {
    "msg": [
        "172.16.1.100"
    ]
}

Attaches a change event to the select that gets the text for each selected option and writes them in the div.

You can use jQuery it very face and successful and easy to use

<select name="sweets" multiple="multiple">
  <option>Chocolate</option>
  <option>Candy</option>
  <option>Taffy</option>
  <option selected="selected">Caramel</option>
  <option>Fudge</option>
  <option>Cookie</option>
</select>
<div></div>


$("select").change(function () {
  var str = "";

  $("select option:selected").each(function() {
    str += $( this ).text() + " ";
  });

  $( "div" ).text( str );
}).change();

Use ipdb

Install it via

pip install ipdb

Usage:

In[1]: def fun1(a):
   def fun2(a):
       import ipdb; ipdb.set_trace() # debugging starts here
       return do_some_thing_about(b)
   return fun2(a)
In[2]: fun1(1)

For executing line by line use n and for step into a function use s and to exit from debugging prompt use c.

Use the "has attribute" selector:

$('p[MyTag]')

Or to select one where that attribute has a specific value:

$('p[MyTag="Sara"]')

There are other selectors for "attribute value starts with", "attribute value contains", etc.

use get instead of load

// ...
        try {
            session = HibernateUtil.getSessionFactory().openSession();
            user =  (User) session.get(User.class, user_id);
        } catch (Exception e) {
 // ...

Runtime rt = Runtime.getRuntime();
rt.maxMemory()

value is b

ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
am.getMemoryClass()

value is MB

You can use Jquery's on method and listen for the scroll event.

You need to do something like the following to disable cell selection within the cellForRowAtIndexPath method:

[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
[cell setUserInteractionEnabled:NO];

To show the cell grayed out, put the following within the tableView:WillDisplayCell:forRowAtIndexPath method:

[cell setAlpha:0.5];

One method allows you to control the interactivity, the other allows you to control the UI appearance.

As with all date manipulation you have to use NSDateComponents and NSCalendar

NSDate *now = [NSDate date];
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier: NSCalendarIdentifierGregorian];
NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay fromDate:now];
[components setHour:10];
NSDate *today10am = [calendar dateFromComponents:components];

in iOS8 Apple introduced a convenience method that saves a few lines of code:

NSDate *d = [calendar dateBySettingHour:10 minute:0 second:0 ofDate:[NSDate date] options:0];

Swift:

let calendar: NSCalendar! = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
let now: NSDate! = NSDate()

let date10h = calendar.dateBySettingHour(10, minute: 0, second: 0, ofDate: now, options: NSCalendarOptions.MatchFirst)!

Use the size() function.

>> size(A,2)

Ans =

   3

The second argument specifies the dimension of which number of elements are required which will be '2' if you want the number of columns.

If you're printing to stdout, it depends on the terminal you're printing to. You can use ansi escape codes on xterms and other similar terminal emulators. Here's a bash code snippet that will print all 255 colors supported by xterm, putty and Konsole:

 for ((i=0;i<256;i++)); do echo -en "\e[38;5;"$i"m"$i" "; done

You can use these escape codes in any programming language. It's better to rely on a library that will decide which codes to use depending on architecture and the content of the TERM environment variable.

The compiler is telling you that there are problems starting at line 122 in the middle of that strange FBI-CIA warning message. That message is not valid C++ code and is NOT commented out so of course it will cause compiler errors. Try removing that entire message.

Also, I agree with In silico: you should always tell us what you tried and exactly what error messages you got.

I faced same error but in a different way.

When you curl a page with a specific SSL protocol.

curl --sslv3 https://example.com

If --sslv3 is not supported by the target server then the error will be

curl: (35) TCP connection reset by peer

With the supported protocol, error will be gone.

curl --tlsv1.2 https://example.com

The class.__stuff naming convention lets the programmer know he isn't meant to access __stuff from outside. The name mangling makes it unlikely anyone will do it by accident.

True, you still can work around this, it's even easier than in other languages (which BTW also let you do this), but no Python programmer would do this if he cares about encapsulation.

According to Microsoft, the allocation unit size "Specifies the cluster size for the file system" - so it is the value shown for "Bytes Per Cluster" as shown in:

You can create an array with all elements from a given Swift Set simply with

let array = Array(someSet)

This works because Set conforms to the SequenceType protocol and an Array can be initialized with a sequence. Example:

let mySet = Set(["a", "b", "a"])  // Set<String>
let myArray = Array(mySet)        // Array<String>
print(myArray) // [b, a]

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

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

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

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

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

I think what @korona meant was since it's just a C API, you can consume it from C# directly with a heck of a lot of typing like this:

[DllImport("opengl32")]
public static extern void glVertex3f(float x, float y, float z);

You unfortunately would need to do this for every single OpenGL function you call, and is basically what Tao has done for you.

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

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

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