Use this code spinet for create intermediate folders if one doesn't exist while creating/editing file:

File outFile = new File("/dir1/dir2/dir3/test.file");
outFile.getParentFile().mkdirs();
outFile.createNewFile();

var id = $(this).dataset.id

works for me!

If you'd checked the results of stream.Read, you'd have seen that it hadn't read anything - because you haven't rewound the stream. (You could do this with stream.Position = 0;.) However, it's easier to just call ToArray:

settingsString = LocalEncoding.GetString(stream.ToArray());

(You'll need to change the type of stream from Stream to MemoryStream, but that's okay as it's in the same method where you create it.)

Alternatively - and even more simply - just use StringWriter instead of StreamWriter. You'll need to create a subclass if you want to use UTF-8 instead of UTF-16, but that's pretty easy. See this answer for an example.

I'm concerned by the way you're just catching Exception and assuming that it means something harmless, by the way - without even logging anything. Note that using statements are generally cleaner than writing explicit finally blocks.

I know this is an old question but I just want to comment here: To any extent email addresses ARE case sensitive, most users would be "very unwise" to actively use an email address that requires capitals. They would soon stop using the address because they'd be missing a lot of their mail. (Unless they have a specific reason to make things difficult, and they expect mail only from specific senders they know.)

That's because imperfect humans as well as imperfect software exist, (Surprise!) which will assume all email is lowercase, and for this reason these humans and software will send messages using a "lower cased version" of the address regardless of how it was provided to them. If the recipient is unable to receive such messages, it won't be long before they notice they're missing a lot, and switch to a lowercase-only email address, or get their server set up to be case-insensitive.

Use grep and regular expressions, for example if you want 4 minutes interval of logs:

grep "31/Mar/2002:19:3[1-5]" logfile

will return all logs lines between 19:31 and 19:35 on 31/Mar/2002. Supposing you need the last 5 days starting from today 27/Sep/2011 you may use the following:

grep "2[3-7]/Sep/2011" logfile

The only thing that worked for me was a combination of the above:

First the li in the ul

<li><a onclick="LoadTab2_1()" href="JavaScript:void(0)">All Assigned</a></li>

Then in the LoadTab2_1 I manually switched the tab divs.

$("#tabs-2-1").hide();
    $("#tabs-2-2").show();

This is because the disconnection of the also disconnects the action in the tabs.

You also need to manually do the tab styling when the primary tab changes things.

$("#secTab1").addClass("ui-tabs-active").addClass("ui-state-active").addClass("ui-state-hover").addClass("ui-state-focus");
    $("#secTab1 a").css("color", "#ffffff");

The code I'll give you works and retrieves not only keys, but a lot of data from a table in SQL Server. Is tested in SQL Server 2k5/2k8, dunno about 2k. Enjoy!

You can use only the primary key part, but I think that the rest might become handy. Best regards, David

I think that for simple HTTP requests like this it's better to use the request module. You need to install it with npm (npm install request) and then your code can look like this:

const request = require('request')
     ,url = 'http://graph.facebook.com/517267866/?fields=picture'

request(url, (error, response, body)=> {
  if (!error && response.statusCode === 200) {
    const fbResponse = JSON.parse(body)
    console.log("Got a response: ", fbResponse.picture)
  } else {
    console.log("Got an error: ", error, ", status code: ", response.statusCode)
  }
})

To see the devices I was interested in, I had replace Win32_USBHub by Win32_PnPEntity in Adel Hazzah's code, based on this post. This works for me:

namespace ConsoleApplication1
{
  using System;
  using System.Collections.Generic;
  using System.Management; // need to add System.Management to your project references.

  class Program
  {
    static void Main(string[] args)
    {
      var usbDevices = GetUSBDevices();

      foreach (var usbDevice in usbDevices)
      {
        Console.WriteLine("Device ID: {0}, PNP Device ID: {1}, Description: {2}",
            usbDevice.DeviceID, usbDevice.PnpDeviceID, usbDevice.Description);
      }

      Console.Read();
    }

    static List<USBDeviceInfo> GetUSBDevices()
    {
      List<USBDeviceInfo> devices = new List<USBDeviceInfo>();

      ManagementObjectCollection collection;
      using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_PnPEntity"))
        collection = searcher.Get();      

      foreach (var device in collection)
      {
        devices.Add(new USBDeviceInfo(
        (string)device.GetPropertyValue("DeviceID"),
        (string)device.GetPropertyValue("PNPDeviceID"),
        (string)device.GetPropertyValue("Description")
        ));
      }

      collection.Dispose();
      return devices;
    }
  }

  class USBDeviceInfo
  {
    public USBDeviceInfo(string deviceID, string pnpDeviceID, string description)
    {
      this.DeviceID = deviceID;
      this.PnpDeviceID = pnpDeviceID;
      this.Description = description;
    }
    public string DeviceID { get; private set; }
    public string PnpDeviceID { get; private set; }
    public string Description { get; private set; }
  }
}

If I understand your question correctly, you need %p to show the address that a pointer is using, for example:

int main() {
    int a = 5;
    int *p = &a;
    printf("%d, %u, %p", p, p, p);

    return 0;
}

will output something like:

-1083791044, 3211176252, 0xbf66a93c

I'm able to run an SQL query by piping it to SQL*Plus:

@echo select count(*) from table; | sqlplus username/password@database

Give

@echo execute some_procedure | sqlplus username/password@databasename

a try.

Unless you need more than just the contents of the file, you could use file_get_contents.

$xml = file_get_contents("http://www.example.com/file.xml");

For anything more complex, I'd use cURL.

Elaborating on the answer provided by Brian R. Bondy: Here's an example that shows why you can't simply size the output buffer to the number of wide characters in the source string:

#include <windows.h>
#include <stdio.h>
#include <wchar.h>
#include <string.h>

/* string consisting of several Asian characters */
wchar_t wcsString[] = L"\u9580\u961c\u9640\u963f\u963b\u9644";

int main() 
{

    size_t wcsChars = wcslen( wcsString);

    size_t sizeRequired = WideCharToMultiByte( 950, 0, wcsString, -1, 
                                               NULL, 0,  NULL, NULL);

    printf( "Wide chars in wcsString: %u\n", wcsChars);
    printf( "Bytes required for CP950 encoding (excluding NUL terminator): %u\n",
             sizeRequired-1);

    sizeRequired = WideCharToMultiByte( CP_UTF8, 0, wcsString, -1,
                                        NULL, 0,  NULL, NULL);
    printf( "Bytes required for UTF8 encoding (excluding NUL terminator): %u\n",
             sizeRequired-1);
}

And the output:

Wide chars in wcsString: 6
Bytes required for CP950 encoding (excluding NUL terminator): 12
Bytes required for UTF8 encoding (excluding NUL terminator): 18

new allocates objects on the heap. Otherwise, objects are allocated on the stack. Look up the difference between the two.

The headers only remain fixed when the UITableViewStyle property of the table is set to UITableViewStylePlain. If you have it set to UITableViewStyleGrouped, the headers will scroll up with the cells.

If you will apply security="none" then no csrf token will be generated. The page will not pass through security filter. Use role ANONYMOUS.

I have not gone in details, but it is working for me.

An Oracle DATE does not store times with more precision than a second. You cannot store millisecond precision data in a DATE column.

Your two options are to either truncate the string of the milliseconds before converting it into a DATE, i.e.

to_date( substr('23.12.2011 13:01:001', 1, 19), 'DD.MM.YYYY HH24:MI:SS' )

or to convert the string into a TIMESTAMP that does support millisecond precision

to_timestamp( '23.12.2011 13:01:001', 'DD.MM.YYYY HH24:MI:SSFF3' )

Python dicts are not sorted, by definition. You cannot sort one, nor control the order of its elements by how you insert them. You might want to look at collections.OrderDict, which even comes with a little tutorial for almost exactly what you're trying to do: http://docs.python.org/2/library/collections.html#ordereddict-examples-and-recipes

You are missing # hash character before id selectors, this should work:

$(document).ready(function() {
    $("#div2").hide();

    $("#preview").click(function() {
      $("#div1").hide();
      $("#div2").show();
    });

});

You can use this method in the ObjectUtils class from org.apache.commons.lang3 library :

public static <T> T defaultIfNull(T object, T defaultValue)

You have to first clear the table and then add new data using row.add() function. At last step adjust also column size so that table renders correctly.

$('#upload-new-data').on('click', function () {
   datatable.clear().draw();
   datatable.rows.add(NewlyCreatedData); // Add new data
   datatable.columns.adjust().draw(); // Redraw the DataTable
});

Also if you want to find a mapping between old and new datatable API functions bookmark this

In Swift 4.2 and Xcode 10

if UIDevice().userInterfaceIdiom == .phone {
    //This is iPhone
} else if UIDevice().userInterfaceIdiom == .pad { 
    //This is iPad
} else if UIDevice().userInterfaceIdiom == .tv {
    //This is Apple TV
}

If you want to detect specific device

let screenHeight = UIScreen.main.bounds.size.height
if UIDevice().userInterfaceIdiom == .phone {
    if (screenHeight >= 667) {
        print("iPhone 6 and later")
    } else if (screenHeight == 568) {
        print("SE, 5C, 5S")
    } else if(screenHeight<=480){
        print("4S")
    }
} else if UIDevice().userInterfaceIdiom == .pad { 
    //This is iPad
}

Make use of Arrow functions it improves the readability of code. No need to return anything in API.fetchComments, Api call is asynchronous when the request is completed then will get the response, there you have to just dispatch type and data.

Below code does the same job by making use of Arrow functions.

export const bindComments = postId => {
  return dispatch => {
    API.fetchComments(postId).then(comments => {
      dispatch({
        type: BIND_COMMENTS,
        comments,
        postId
      });
    });
  };
};

A modification of the code by @CarloCannas:

public static void sudo(String...strings) {
    try{
        Process su = Runtime.getRuntime().exec("su");
        DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());

        for (String s : strings) {
            outputStream.writeBytes(s+"\n");
            outputStream.flush();
        }

        outputStream.writeBytes("exit\n");
        outputStream.flush();
        try {
            su.waitFor();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        outputStream.close();
    }catch(IOException e){
        e.printStackTrace();
    }
}

(You are welcome to find a better place for outputStream.close())

Usage example:

private static void suMkdirs(String path) {
    if (!new File(path).isDirectory()) {
        sudo("mkdir -p "+path);
    }
}

Update: To get the result (the output to stdout), use:

public static String sudoForResult(String...strings) {
    String res = "";
    DataOutputStream outputStream = null;
    InputStream response = null;
    try{
        Process su = Runtime.getRuntime().exec("su");
        outputStream = new DataOutputStream(su.getOutputStream());
        response = su.getInputStream();

        for (String s : strings) {
            outputStream.writeBytes(s+"\n");
            outputStream.flush();
        }

        outputStream.writeBytes("exit\n");
        outputStream.flush();
        try {
            su.waitFor();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        res = readFully(response);
    } catch (IOException e){
        e.printStackTrace();
    } finally {
        Closer.closeSilently(outputStream, response);
    }
    return res;
}
public static String readFully(InputStream is) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    byte[] buffer = new byte[1024];
    int length = 0;
    while ((length = is.read(buffer)) != -1) {
        baos.write(buffer, 0, length);
    }
    return baos.toString("UTF-8");
}

The utility to silently close a number of Closeables (So?ket may be no Closeable) is:

public class Closer {
// closeAll()
public static void closeSilently(Object... xs) {
    // Note: on Android API levels prior to 19 Socket does not implement Closeable
    for (Object x : xs) {
        if (x != null) {
            try {
                Log.d("closing: "+x);
                if (x instanceof Closeable) {
                    ((Closeable)x).close();
                } else if (x instanceof Socket) {
                    ((Socket)x).close();
                } else if (x instanceof DatagramSocket) {
                    ((DatagramSocket)x).close();
                } else {
                    Log.d("cannot close: "+x);
                    throw new RuntimeException("cannot close "+x);
                }
            } catch (Throwable e) {
                Log.x(e);
            }
        }
    }
}
}

1. PYTHONPATH is an environment variable
2. Yes (see https://unix.stackexchange.com/questions/24802/on-which-unix-distributions-is-python-installed-as-part-of-the-default-install)
3. /usr/lib/python2.7 on Ubuntu
4. you shouldn't install packages manually. Instead, use pip. When a package isn't in pip, it usually has a setuptools setup script which will install the package into the proper location (see point 3).
5. if you use pip or setuptools, then you don't need to set PYTHONPATH explicitly

If you look at the instructions for pyopengl, you'll see that they are consistent with points 4 and 5.

In monodroid, you can do like this for rounded rectangle, and then keeping this as a parent class, editbox and other layout features can be added.

 class CustomeView : TextView
    {
       public CustomeView (Context context, IAttributeSet ) : base (context, attrs)  
        {  
        }
       public CustomeView(Context context, IAttributeSet attrs, int defStyle) : base(context, attrs, defStyle)  
        {  
        }
       protected override void OnDraw(Android.Graphics.Canvas canvas)
       {
           base.OnDraw(canvas);
           Paint p = new Paint();
           p.Color = Color.White;
           canvas.DrawColor(Color.DarkOrange);

           Rect rect = new Rect(0,0,3,3);

           RectF rectF = new RectF(rect);


           canvas.DrawRoundRect( rectF, 1,1, p);



       }  
    }
}

Tomcat is primarily an application server, which serves requests to custom-built Java servlets or JSP files on your server. It is usually used in conjunction with the Apache HTTP server (at least in my experience). Use it to manually process incoming requests.

The HTTP server, by itself, is best for serving up static content... html files, images, etc.

//BEWARE
//This works ONLY if the server returns 401 first
//The client DOES NOT send credentials on first request
//ONLY after a 401
client.Credentials = new NetworkCredential(userName, passWord); //doesnt work

//So use THIS instead to send credentials RIGHT AWAY
string credentials = Convert.ToBase64String(
    Encoding.ASCII.GetBytes(userName + ":" + password));
client.Headers[HttpRequestHeader.Authorization] = string.Format(
    "Basic {0}", credentials);

<button type="button" onclick="location.href='@Url.Action("MyAction", "MyController")'" />

type="button" prevents page from submitting. instead it performs your action.

You can also delete all tables from database using only MSSMS UI tools (without using SQL script). Sometimes this way can be more comfortable (especially if it is performed occasionally)

I do this step by step as follows:

1. Select 'Tables' on the database tree (Object Explorer)
2. Press F7 to open Object Explorer Details view
3. In this view select tables which have to be deleted (in this case all of them)
4. Keep pressing Delete until all tables have been deleted (you repeat it as many times as amount of errors due to key constraints/dependencies)

It is terrible, but you can try to use

select
SUBSTRING(Table1.Col1,0,PATINDEX('%|%=',Table1.Col1)) as myString
from
Table1

This code is probably not 100% right though. need to be adjusted

This worked for me:

If you wrote your Serialized class object into a file, then made some changes to file and compiled it, and then you try to read an object, then this will happen.

So, write the necessary objects to file again if a class is modified and recompiled.

PS: This is NOT a solution; was meant to be a workaround.

int *a[], when used as a function parameter (but not in normal declarations), is a pointer to a pointer, not a pointer to an array (in normal declarations, it is an array of pointers). A pointer to an array looks like this:

int (*aptr)[N]

Where N is a particular positive integer (not a variable).

If you make your function a template, you can do it and you don't even need to pass the size of the array (because it is automatically deduced):

template<size_t SZ>
void generateArray(int (*aptr)[SZ])
{
    for (size_t i=0; i<SZ; ++i)
        (*aptr)[i] = rand() % 9;
}

int main()
{    
    int a[5];    
    generateArray(&a);
}

You could also take a reference:

template<size_t SZ>
void generateArray(int (&arr)[SZ])
{
    for (size_t i=0; i<SZ; ++i)
        arr[i] = rand() % 9;
}

int main()
{    
    int a[5];    
    generateArray(a);
}

Dont make name with capital letters . Always use lowercase for naming . This will work fine . like companyLogo.png will raise error but company_logo.png will work fine.

'Date' is your index so you want to do,

print (df.index.min())
print (df.index.max())

2014-03-13 00:00:00
2014-03-31 00:00:00

If after changing the namespace and the config/auth.php it still fails, you could try the following:

1. In the file vendor/composer/autoload_classmap.php change the line App\\User' => $baseDir . '/app/User.php',, to App\\Models\\User' => $baseDir . '/app/Models/User.php',

2. At the beginning of the file app/Services/Registrar.php change "use App\User" to "App\Models\User"

try changing this part,

<input type="checkbox" name="newsletter[]" value="newsletter" checked>i want to sign up   for newsletter

for this

<input type="checkbox" name="newsletter" value="newsletter" checked>i want to sign up   for newsletter

For linux users, you should know the following:

1. $CLASSPATH is specifically what Java uses to look through multiple directories to find all the different classes it needs for your script (unless you explicitly tell it otherwise with the -cp override). Using -cp (--classpath) requires that you keep track of all the directories manually and copy-paste that line every time you run the program (not preferable IMO).

2. The colon (":") character separates the different directories. There is only one $CLASSPATH and it has all the directories in it. So, when you run "export CLASSPATH=...." you want to include the current value "$CLASSPATH" in order to append to it. For example:

   export CLASSPATH=.
   export CLASSPATH=$CLASSPATH:/usr/share/java/mysql-connector-java-5.1.12.jar
   

   In the first line above, you start CLASSPATH out with just a simple 'dot' which is the path to your current working directory. With that, whenever you run java it will look in the current working directory (the one you're in) for classes. In the second line above, $CLASSPATH grabs the value that you previously entered (.) and appends the path to a mysql dirver. Now, java will look for the driver AND for your classes.

3. echo $CLASSPATH
   

   is super handy, and what it returns should read like a colon-separated list of all the directories you want java looking in for what it needs to run your script.

4. Tomcat does not use CLASSPATH. Read what to do about that here: https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

Try:

UPDATE table1
SET CalculatedColumn = ( SELECT [Calculated Column] 
                         FROM table2 
                         WHERE table1.commonfield = [common field])
WHERE  BatchNO = '110'

Same thing you'd expect from normal modulo .. e.g. 7 % 4 = 3, 7.3 % 4.0 = 3.3

Beware of floating point accuracy issues.

To repeat 7 times, try to use a an array with length=7, then track it by $index:

<span ng-repeat="a in (((b=[]).length=7)&&b) track by $index" ng-bind="$index + 1 + ', '"></span>

b=[] create an empty Array «b»,
.length=7 set it's size to «7»,
&&b let the new Array «b» be available to ng-repeat,
track by $index where «$index» is the position of iteration.
ng-bind="$index + 1" display starting at 1.

To repeat X times:
just replace 7 by X.

Here's my effort to give a more complete answer (building on @john's answer).

The initial issue I encountered was changing the width and height of a canvas node (using styles), resulted in the contents just being "zoomed" or "shrunk." This was not the desired effect.

So, say you want to draw two rectangles of arbitrary size in a canvas that is 100px by 100px.

<canvas width="100" height="100"></canvas>

To ensure that the rectangles will not exceed the size of the canvas and therefore not be visible, you need to ensure that the canvas is big enough.

var $canvas = $('canvas'),
    oldCanvas,
    context = $canvas[0].getContext('2d');

function drawRects(x, y, width, height)

  if (($canvas.width() < x+width) || $canvas.height() < y+height)
  {
    oldCanvas = $canvas[0].toDataURL("image/png")
    $canvas[0].width = x+width;
    $canvas[0].height = y+height;

    var img = new Image();
    img.src = oldCanvas;
    img.onload = function (){
      context.drawImage(img, 0, 0);
    };
  }
  context.strokeRect(x, y, width, height);
}


drawRects(5,5, 10, 10);
drawRects(15,15, 20, 20);
drawRects(35,35, 40, 40);
drawRects(75, 75, 80, 80);

Finally, here's the jsfiddle for this: http://jsfiddle.net/Rka6D/4/ .

On Linux or MingW, with GNU toolchain:

ar -M <<EOM
    CREATE libab.a
    ADDLIB liba.a
    ADDLIB libb.a
    SAVE
    END
EOM
ranlib libab.a

Of if you do not delete liba.a and libb.a, you can make a "thin archive":

ar crsT libab.a liba.a libb.a

On Windows, with MSVC toolchain:

lib.exe /OUT:libab.lib liba.lib libb.lib

Create a separate JavaScript function that can be called to close the dialog using the specific object id, and place the function outside of $(document).ready() like this:

function closeDialogWindow() { 
$('#dialogWindow').dialog('close');
}

NOTE: The function must be declared outside of $(document).ready() so jQuery doesn't try to trigger the close event on the dialog before it is created in the DOM.

In my case it was a folder with olders DLLs of the same name that those wich were referenced in my .csproj file although the path was explicitly given they were somehow included therefore the several versions of the same DLLs were in conflict.

Run this command, to check error logs:

tail -f /var/log/nginx/error.log

Adding the async keyword is just syntactic sugar to simplify the creation of a state machine. In essence, the compiler takes your code;

public async Task MethodName()
{
     return null;
}

And turns it into;

public Task MethodName()
{
     return Task.FromResult<object>(null);
}

If your code has any await keywords, the compiler must take your method and turn it into a class to represent the state machine required to execute it. At each await keyword, the state of variables and the stack will be preserved in the fields of the class, the class will add itself as a completion hook to the task you are waiting on, then return.

When that task completes, your task will be executed again. So some extra code is added to the top of the method to restore the state of variables and jump into the next slab of your code.

See What does async & await generate? for a gory example.

This process has a lot in common with the way the compiler handles iterator methods with yield statements.

I had the same issue, the easiest way i found to insert the current date into a prepared statement is this one:

preparedStatement.setDate(1, new java.sql.Date(new java.util.Date().getTime()));

It's kind of a pain to position, but you could use 1px wide divs as lines and position and rotate them appropriately.

http://jsfiddle.net/sbaBG/1

<div class="box" id="box1"></div>
<div class="box" id="box2"></div>
<div class="box" id="box3"></div>

<div class="line" id="line1"></div>
<div class="line" id="line2"></div>

.box {
    border: 1px solid black;
    background-color: #ccc;
    width: 100px;
    height: 100px;
    position: absolute;
}
.line {
    width: 1px;
    height: 100px;
    background-color: black;
    position: absolute;
}
#box1 {
    top: 0;
    left: 0;
}
#box2 {
    top: 200px;
    left: 0;
}
#box3 {
    top: 250px;
    left: 200px;
}
#line1 {
    top: 100px;
    left: 50px;
}
#line2 {
    top: 220px;
    left: 150px;
    height: 115px;

    transform: rotate(120deg);
    -webkit-transform: rotate(120deg);
    -ms-transform: rotate(120deg);
}

Evidently, the compiler was made in a confusing way although the compiler developers thought they added some smartness. The true smartness they should really add is to look entire argument and interpret + operator consistently. For example, System.out.println(1+2+"hello"+3+4); should output 3hello7 instead of 3hello34

As an alternative to rendering a raster image, you can embed a SVG:

https://gist.github.com/CyberShadow/95621a949b07db295000

Unfortunately, even though you can select and copy text when you open the .svg file, the text is not selectable when the SVG image is embedded.

In additional you should disable your antivirus or manage it to open 80 port on your system.

The syntax is wrong in this clause (and similar ones)

    CASE lkey WHEN lkey > 5 THEN
        lkey + 2
    ELSE
        lkey
    END

It's either

    CASE WHEN [condition] THEN [expression] ELSE [expression] END

or

    CASE [expression] WHEN [value] THEN [expression] ELSE [expression] END

So in your case it would read:

    CASE WHEN lkey > 5 THEN
        lkey + 2
    ELSE
        lkey
    END

Check out the documentation (The CASE expression):

http://www.sqlite.org/lang_expr.html

It sounds like your response is being evaluated somehow. This gives the same error in Chrome:

var resp = '{"votes":47,"totalvotes":90}';
eval(resp);

This is due to the braces '{...}' being interpreted by javascript as a code block and not an object literal as one might expect.

I would look at the JSON.decode() function and see if there is an eval in there.

Similar issue here: Eval() = Unexpected token : error

I just thought I'd share that I found the answer to my own question.

Writing out my problem made it even more clear to me, and I further investigated into where I thought my problem lay: the ssh key

Turns out I was right. The issue wasn't with the key itself, but rather that I had not added it to my local Mac's list of known ssh keys. So even though my Heroku account had the correct key uploaded, my Mac could not authenticate with it because it could not find that key on my computer. The solution?

ssh-add ~/.ssh/id_rsa
#and, to confirm it's been added to the known list of keys
ssh-add -l

I would like to give credit to https://help.github.com/articles/error-permission-denied-publickey for being a good reference.

Make your Project and Workspace to point to JDK7 which will resolve the issue. https://developers.google.com/eclipse/docs/jdk_compliance has given ways to modify Compliance and Facet level changes.

How about using an input group to style it on the same line?

Here's the final HTML to use:

<div class="input-group">
    <input type="text" class="form-control" placeholder="Start"/>
    <span class="input-group-addon">-</span>
    <input type="text" class="form-control" placeholder="End"/>
</div>

Which will look like this:

Scripts

Nobody has proposed this simple plain-text solution:

from pprint import pprint

pprint(s.to_dict())

which produces results like the following:

{'% Diabetes': 0.06365372374283895,
 '% Obesity': 0.06365372374283895,
 '% Bachelors': 0.0,
 '% Poverty': 0.09548058561425843,
 '% Driving Deaths': 1.1775938892425206,
 '% Excessive Drinking': 0.06365372374283895}

Jupyter Notebooks

Additionally, when using Jupyter notebooks, this is a great solution.

Note: pd.Series() has no .to_html() so it must be converted to pd.DataFrame()

from IPython.display import display, HTML

display(HTML(s.to_frame().to_html()))

which produces results like the following:

Here is a filter that will take a date string OR javascript Date() object. It uses Moment.js and can apply any Moment.js transform function, such as the popular 'fromNow'

angular.module('myModule').filter('moment', function () {
  return function (input, momentFn /*, param1, param2, ...param n */) {
    var args = Array.prototype.slice.call(arguments, 2),
        momentObj = moment(input);
    return momentObj[momentFn].apply(momentObj, args);
  };
});

So...

{{ anyDateObjectOrString | moment: 'format': 'MMM DD, YYYY' }}

would display Nov 11, 2014

{{ anyDateObjectOrString | moment: 'fromNow' }}

would display 10 minutes ago

If you need to call multiple moment functions, you can chain them. This converts to UTC and then formats...

{{ someDate | moment: 'utc' | moment: 'format': 'MMM DD, YYYY' }}

To get the values use

sorted(data.values())

To get the matching keys, use a key function

sorted(data, key=data.get)

To get a list of tuples ordered by value

sorted(data.items(), key=lambda x:x[1])

Related: see the discussion here: Dictionaries are ordered in Python 3.6+

To convert the private key from PKCS#1 to PKCS#8 with openssl:

# openssl pkcs8 -topk8 -inform PEM -outform PEM -nocrypt -in pkcs1.key -out pkcs8.key

That will work as long as you have the PKCS#1 key in PEM (text format) as described in the question.

There is no automatic addition of app.config file when you add a class library project to your solution.

To my knowledge, there is no counter indication about doing so manualy. I think this is a common usage.

About log4Net config, you don't have to put the config into app.config, you can have a dedicated conf file in your project as well as an app.config file at the same time.

this link http://logging.apache.org/log4net/release/manual/configuration.html will give you examples about both ways (section in app.config and standalone log4net conf file)

The pickle (and gzip if the file is compressed) module need to be used

NOTE: These are already in the standard Python library. No need to install anything new

Use MySQL's spatial extensions with GIS.

I am using this, both smaller and large images:

.product p.image {
text-align: center;
width: 220px;
height: 160px;
overflow: hidden;
}
.product p.image img{
max-width: 100%;
max-height: 100%;
}

I know that this has been asked more than three years ago. But the answer accepted is not extremely useful.

The following code is more useful.

<?php
$File = 'loginevents.csv';

$arrResult  = array();
$handle     = fopen($File, "r");
if(empty($handle) === false) {
    while(($data = fgetcsv($handle, 1000, ",")) !== FALSE){
        $arrResult[] = $data;
    }
    fclose($handle);
}
print_r($arrResult);
?>

As others mentioned, you could use JDialog. If you don't have access to the parent frame or you want to freeze the hole application just pass null as a parent:

final JDialog frame = new JDialog((JFrame)null, frameTitle, true); frame.setModal(true);
frame.getContentPane().add(panel);
frame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
frame.pack();
frame.setVisible(true);

 String strWebData="html...." //**Your html string**

 WebView webDetail=(WebView) findViewById(R.id.webView1);

 WebSettings websetting = webDetail.getSettings();

 websetting.setDefaultTextEncodingName("utf-8");

 webDetail.loadData(strWebData, "text/html; charset=utf-8", null);

Use,..

Color.parseColor("#bdbdbd");

like,

mTextView.setTextColor(Color.parseColor("#bdbdbd"));

Or if you have defined color code in resource's color.xml file than

(From API >= 23)

mTextView.setTextColor(ContextCompat.getColor(context, R.color.<name_of_color>));

(For API < 23)

mTextView.setTextColor(getResources().getColor(R.color.<name_of_color>));

An alternative:

var scrollleft = 1000;
switch (true)
{
    case (scrollleft > 1000):
      alert('gt');
      break;
    case (scrollleft <= 1000):
      alert('lt');
      break; 
}

For swift

var label = UILabel(frame: CGRect(x: 0, y: 0, width: 250, height: 50))
label.textAlignment = .left
label.text = "This is a Label"
self.view.addSubview(label)

Android actually has an API for this! The method is setMediaPlaybackRequiresUserGesture(). I found it after a lot of digging into video autoplay and a lot of attempted hacks from SO. Here's an example from blair vanderhoof:

package com.example.myProject;

import android.os.Bundle;
import org.apache.cordova.*;
import android.webkit.WebSettings;

public class myProject extends CordovaActivity 
{
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        super.init();
        // Set by <content src="index.html" /> in config.xml
        super.loadUrl(Config.getStartUrl());
        //super.loadUrl("file:///android_asset/www/index.html");

        WebSettings ws = super.appView.getSettings();
        ws.setMediaPlaybackRequiresUserGesture(false);
    }
}

I think you'd be interested in the H1 debate. It's a debate about whether to use the h1 element for the page's title or for the logo.

Personally I'd go with your first suggestion, something along these lines:

<div id="header">
    <a href="http://example.com/"><img src="images/logo.png" id="site-logo" alt="MyCorp" /></a>
</div>

<!-- or alternatively (with css in a stylesheet ofc-->
<div id="header">
    <div id="logo" style="background: url('logo.png'); display: block; 
        float: left; width: 100px; height: 50px;">
        <a href="#" style="display: block; height: 50px; width: 100px;">
            <span style="visibility: hidden;">Homepage</span>
        </a>
    </div>
    <!-- with css in a stylesheet: -->
    <div id="logo"><a href="#"><span>Homepage</span></a></div>
</div>


<div id="body">
    <h1>About Us</h1>
    <p>MyCorp has been dealing in narcotics for over nine-thousand years...</p>
</div>

Of course this depends on whether your design uses page titles but this is my stance on this issue.

Do keep in mind that you don't need a stable sort if you compare all members. The 2.0 solution, as requested, can look like this:

 public void SortList() {
     MyList.Sort(delegate(MyClass a, MyClass b)
     {
         int xdiff = a.x.CompareTo(b.x);
         if (xdiff != 0) return xdiff;
         else return a.y.CompareTo(b.y);
     });
 }

Do note that this 2.0 solution is still preferable over the popular 3.5 Linq solution, it performs an in-place sort and does not have the O(n) storage requirement of the Linq approach. Unless you prefer the original List object to be untouched of course.

Adding this to project's gradle.properties fixed it for us:

android.enableJetifier=true
android.useAndroidX=true

ldapConnection is the server adres: ldap.example.com Ldap.Connection.Path is the path inside the ADS that you like to use insert in LDAP format.

OU=Your_OU,OU=other_ou,dc=example,dc=com

You start at the deepest OU working back to the root of the AD, then add dc=X for every domain section until you have everything including the top level domain

Now i miss a parameter to authenticate, this works the same as the path for the username

CN=username,OU=users,DC=example,DC=com

Introduction to LDAP

Reason for adding an answer at this moment:

So far I was adding the conclusion and ‘answers’ to my initial question itself, making the question very lengthy, hence moving to separate answer.

I have also added more frequently used git commands that helps me on git, to help someone else too.

Basically to clean all local commits $ git reset --hard and $ git clean -d -f

First step before you do any commits is to configure your username and email that appears along with your commit.

#Sets the name you want attached to your commit transactions

$ git config --global user.name "[name]"

#Sets the email you want atached to your commit transactions

$ git config --global user.email "[email address]"

#List the global config

$ git config --list

#List the remote URL

$ git remote show origin

#check status

git status

#List all local and remote branches

git branch -a

#create a new local branch and start working on this branch

git checkout -b "branchname" 

or, it can be done as a two step process

create branch: git branch branchname work on this branch: git checkout branchname

#commit local changes [two step process:- Add the file to the index, that means adding to the staging area. Then commit the files that are present in this staging area]

git add <path to file>

git commit -m "commit message"

#checkout some other local branch

git checkout "local branch name"

#remove all changes in local branch [Suppose you made some changes in local branch like adding new file or modifying existing file, or making a local commit, but no longer need that] git clean -d -f and git reset --hard [clean all local changes made to the local branch except if local commit]

git stash -u also removes all changes

Note: It's clear that we can use either (1) combination of git clean –d –f and git reset --hard OR (2) git stash -u to achieve the desired result.

Note 1: Stashing, as the word means 'Store (something) safely and secretly in a specified place.' This can always be retreived using git stash pop. So choosing between the above two options is developer's call.

Note 2: git reset --hard will delete working directory changes. Be sure to stash any local changes you want to keep before running this command.

# Switch to the master branch and make sure you are up to date.

git checkout master

git fetch [this may be necessary (depending on your git config) to receive updates on origin/master ]

git pull

# Merge the feature branch into the master branch.

git merge feature_branch

# Reset the master branch to origin's state.

git reset origin/master

#Accidentally deleted a file from local , how to retrieve it back? Do a git status to get the complete filepath of the deleted resource

git checkout branchname <file path name>

that's it!

#Merge master branch with someotherbranch

git checkout master
git merge someotherbranchname

#rename local branch

git branch -m old-branch-name new-branch-name

#delete local branch

git branch -D branch-name

#delete remote branch

git push origin --delete branchname

or

git push origin :branch-name

#revert a commit already pushed to a remote repository

git revert hgytyz4567

#branch from a previous commit using GIT

git branch branchname <sha1-of-commit>

#Change commit message of the most recent commit that's already been pushed to remote

git commit --amend -m "new commit message"
git push --force origin <branch-name>

# Discarding all local commits on this branch [Removing local commits]

In order to discard all local commits on this branch, to make the local branch identical to the "upstream" of this branch, simply run

git reset --hard @{u}

Reference: http://sethrobertson.github.io/GitFixUm/fixup.html or do git reset --hard origin/master [if local branch is master]

# Revert a commit already pushed to a remote repository?

$ git revert ab12cd15

#Delete a previous commit from local branch and remote branch

Use-Case: You just commited a change to your local branch and immediately pushed to the remote branch, Suddenly realized , Oh no! I dont need this change. Now do what?

git reset --hard HEAD~1 [for deleting that commit from local branch. 1 denotes the ONE commit you made]

git push origin HEAD --force [both the commands must be executed. For deleting from remote branch]. Currently checked out branch will be referred as the branch where you are making this operation.

#Delete some of recent commits from local and remote repo and preserve to the commit that you want. ( a kind of reverting commits from local and remote)

Let's assume you have 3 commits that you've pushed to remote branch named 'develop'

commitid-1 done at 9am
commitid-2 done at 10am
commitid-3 done at 11am. // latest commit. HEAD is current here.

To revert to old commit ( to change the state of branch)

git log --oneline --decorate --graph // to see all your commitids

git clean -d -f // clean any local changes

git reset --hard commitid-1 // locally reverting to this commitid

git push -u origin +develop // push this state to remote. + to do force push

# Remove local git merge: Case: I am on master branch and merged master branch with a newly working branch phase2

$ git status

On branch master

$ git merge phase2 $ git status

On branch master

Your branch is ahead of 'origin/master' by 8 commits.

Q: How to get rid of this local git merge? Tried git reset --hard and git clean -d -f Both didn't work. The only thing that worked are any of the below ones:

$ git reset --hard origin/master

or

$ git reset --hard HEAD~8

or

$ git reset --hard 9a88396f51e2a068bb7 [sha commit code - this is the one that was present before all your merge commits happened]

#create gitignore file

touch .gitignore // create the file in mac or unix users

If you use the NetBeans IDE (latest version at this time is 6.5.1), you can use it to create a basic GUI java application using File->New Project and choose the Java category then Java Desktop Application.

Once created, you will have a simple bare bones GUI app which contains an about box that can be opened using a menu selection. You should be able to adapt this to your needs and learn how to open a dialog from a button click.

You will be able to edit the dialog visually. Delete the items that are there and add some text areas. Play around with it and come back with more questions if you get stuck :)

At first it seems as if JNZ means jump if not Zero (0), as in jump if zero flag is 1/set.

But in reality it means Jump (if) not Zero (is set).

If 0 = not set and 1 = set then just remember:
JNZ Jumps if the zero flag is not set (0)

Try setting the timeout value in your web service proxy class:

WebReference.ProxyClass myProxy = new WebReference.ProxyClass();
myProxy.Timeout = 100000; //in milliseconds, e.g. 100 seconds

session_start();          //php part
$_SESSION['student']=array();
$student_name=$_POST['student_name']; //student_name form field name
$student_city=$_POST['city_id'];   //city_id form field name
array_push($_SESSION['student'],$student_name,$student_city);   
//print_r($_SESSION['student']);


<table class="table">     //html part
    <tr>
      <th>Name</th>
      <th>City</th>
    </tr>

    <tr>
     <?php for($i = 0 ; $i < count($_SESSION['student']) ; $i++) {
     echo '<td>'.$_SESSION['student'][$i].'</td>';
     }  ?>
    </tr>
</table>

Encountered the same problem. I was doing something like:

connect 'jdbc:derby://localhost:1527/~/databases/db1'

Replacing the path with the absolute path fixed this problem:

connect 'jdbc:derby://localhost:1527//Users/ayush99/databases/db1'.

In summary: Avoid using ~ or any such variables in the path of existing database.

This link helped me a lot for the same problem:

p = ggplot() + 
  geom_line(data = df_plot, aes(x = idx, y = col1), color = "blue") +
  geom_line(data = df_plot, aes(x = idx, y = col2), color = "red") 

print(p)

One more thing to check for this issue is html tag attribute id. You should check any other html tags in that page have the same id as nav tab id.

The options discussed above won't work because they are not part of the CSS specification (it is jQuery extension). Having spent 2-3 days digging around for information, I found that the only way to select the Text of the selected option from the drop down is:

{ $("select", id:"Some_ID").find("option[selected='selected']")}

Refer to additional notes below: Because :selected is a jQuery extension and not part of the CSS specification, queries using :selected cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :selected to select elements, first select the elements using a pure CSS selector, then use .filter(":selected"). (copied from: http://api.jquery.com/selected-selector/)

Make sure you're adding these dependencies in android/app/build.gradle, not android/build.gradle

You can use String#substring()

if(str != null && str.length() > 8) {
    return str.substring(0, 8) + "...";
} else {
    return str;
}

You could however make a function where you pass the maximum number of characters that can be displayed. The ellipsis would then cut in only if the width specified isn't enough for the string.

public String getShortString(String input, int width) {
  if(str != null && str.length() > width) {
      return str.substring(0, width - 3) + "...";
  } else {
      return str;
  }
}

// abcdefgh...
System.out.println(getShortString("abcdefghijklmnopqrstuvwxyz", 11));

// abcdefghijk
System.out.println(getShortString("abcdefghijk", 11)); // no need to trim

Cut the long story short: With relative layout you position elements inside the layout.

1. create a new RelativeLayout.LayoutParams

   RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(...)
   

   (whatever... fill parent or wrap content, absolute numbers if you must, or reference to an XML resource)

2. Add rules: Rules refer to the parent or to other "brothers" in the hierarchy.

   lp.addRule(RelativeLayout.BELOW, someOtherView.getId())
   lp.addRule(RelativeLayout.ALIGN_PARENT_LEFT)
   

3. Just apply the layout params: The most 'healthy' way to do that is:

   parentLayout.addView(myView, lp)
   

Watch out: Don't change layout from the layout callbacks. It is tempting to do so because this is when views get their actual sizes. However, in that case, unexpected results are expected.

How about this? (If you're using jQuery)

var $window = $(window);
var $body = $(window.document.body);

window.onscroll = function() {
    var overlay = $body.children(".ui-widget-overlay").first();

    // Check if the overlay is visible and restore the previous scroll state
    if (overlay.is(":visible")) {
        var scrollPos = $body.data("scroll-pos") || { x: 0, y: 0 };
        window.scrollTo(scrollPos.x, scrollPos.y);
    }
    else {
        // Just store the scroll state
        $body.data("scroll-pos", { x: $window.scrollLeft(), y: $window.scrollTop() });
    }
};

I've made a Python function where you enter the table and column to remove as arguments:

def removeColumn(table, column):
    columns = []
    for row in c.execute('PRAGMA table_info(' + table + ')'):
        columns.append(row[1])
    columns.remove(column)
    columns = str(columns)
    columns = columns.replace("[", "(")
    columns = columns.replace("]", ")")
    for i in ["\'", "(", ")"]:
        columns = columns.replace(i, "")
    c.execute('CREATE TABLE temptable AS SELECT ' + columns + ' FROM ' + table)
    c.execute('DROP TABLE ' + table)
    c.execute('ALTER TABLE temptable RENAME TO ' + table)
    conn.commit()

As per the info on Duda's and MeBigFatGuy's answers this won't work if there is a foreign key on the table, but this can be fixed with 2 lines of code (creating a new table and not just renaming the temporary table)

There is another case where the two possibilities differ, on top of those already mentioned: if you need to call a non-public constructor (protected or private), make_shared might not be able to access it, while the variant with the new works fine.

class A
{
public:

    A(): val(0){}

    std::shared_ptr<A> createNext(){ return std::make_shared<A>(val+1); }
    // Invalid because make_shared needs to call A(int) **internally**

    std::shared_ptr<A> createNext(){ return std::shared_ptr<A>(new A(val+1)); }
    // Works fine because A(int) is called explicitly

private:

    int val;

    A(int v): val(v){}
};

const index = array.findIndex(item => item.id === 'your-id');

This should get you the index of item in array with id === your-id

array = [ {id:1}, {id:2} ];_x000D_
_x000D_
const index = array.findIndex(item => item.id === 2);_x000D_
_x000D_
console.log(index);

Change your main to:

public static void main(String[] args) {
    EchoServer echoServer = new EchoServer();
    echoServer.listen();
}

When you declare Object EchoServer0; you have a few mistakes.

1. EchoServer0 is of type Object, therefore it doesn't have the method listen().
2. You will also need to create an instance of it with new.
3. Another problem, this is only regarding naming conventions, you should call your variables starting by lower case letters, echoServer0 instead of EchoServer0. Uppercase names are usually for class names.
4. You should not create a variable with the same name as its class. It is confusing.

You should provide output file name after -o option. In your case runexp.o is treated as output file name, not input object file and thus your main function is undefined.

Doing this would require to break the browser sandbox. Try to let your server do the lookup and request that from the client side via XmlHttp.

It's not fancy I known but you could use a callback class, create a hostbuilder and set the configuration to a static property.

For asp core 2.2:

using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using System;

namespace Project
{
    sealed class Program
    {

        /// </summary>
        private static IConfiguration _Configuration;
        #endregion

        #region Properties
        /// <summary>
        /// Default application configuration
        /// </summary>
        internal static IConfiguration Configuration
        {
            get
            {
                // None configuration yet?
                if (Program._Configuration == null)
                {
                    // Create the builder using a callback class
                    IWebHostBuilder builder = WebHost.CreateDefaultBuilder().UseStartup<CallBackConfiguration>();

                    // Build everything but do not initialize it
                    builder.Build();
                }

                // Current configuration
                return Program._Configuration;
            }

            // Update configuration
            set => Program._Configuration = value;
        }
        #endregion

        #region Public
        /// <summary>

        public static void Main(string[] args)

            // Create the builder using the default Startup class
            IWebHostBuilder builder = WebHost.CreateDefaultBuilder(args).UseStartup<Startup>();

            // Build everything and run it
            using (IWebHost host = builder.Build())
                host.Run();
        }
        #endregion


        #region CallBackConfiguration
        /// <summary>
        /// Aux class to callback configuration
        /// </summary>
        private class CallBackConfiguration
        {
            /// <summary>
            /// Callback with configuration
            /// </summary>
            public CallBackConfiguration(IConfiguration configuration)
            {
                // Update the last configuration
                Program.Configuration = configuration;
            }

            /// <summary>
            /// Do nothing, just for compatibility

            public void Configure(IApplicationBuilder app, IHostingEnvironment env)
            {
                //
            }
        }
        #endregion
    }
}

So now on you just use the static Program.Configuration at any other class you need it.

If you need Set rather than List, you can use EnumSet.allOf().

Set<EnumerationClass> set = EnumSet.allOf(EnumerationClass.class);

Update: JakeRobb is right. My answer is about java.lang.Enum instead of java.util.Enumeration. Sorry for unrelated answer.

First of all stop all the mongoDB services, then create a directory on / , it means root, if you don't have, and remove the port file also. give all permission to that directory, become that directory owner, run below command:

sudo service mongod stop
sudo rm -rf /tmp/mongod*
sudo mkdir -p /data/db
sudo chmod -R a+wxr /data
sudo chown -R $USER:$USER /data

Now you're done, just start the MongoDB service, if didn't help, try to change the port like:

sudo service mongod restart && mongod # if didn't help run below cmd
mongod --port 27018

Note: For me all this stuff works and hoping would work for you, guy!

The proposed solutions are perfect to download the images and if it is enough for you to save all the files in the directory you are using. But if you want to save all the images in a specified directory without reproducing the entire hierarchical tree of the site, try to add "cut-dirs" to the line proposed by Jon.

wget -r -P /save/location -A jpeg,jpg,bmp,gif,png http://www.boia.de --cut-dirs=1 --cut-dirs=2 --cut-dirs=3

in this case cut-dirs will prevent wget from creating sub-directories until the 3th level of depth in the website hierarchical tree, saving all the files in the directory you specified.You can add more 'cut-dirs' with higher numbers if you are dealing with sites with a deep structure.

You can do a one liner:

str = ...
int = Integer(str) rescue nil

if int
  int.times {|i| p i}
end

or even

int = Integer(str) rescue false

Depending on what you are trying to do you can also directly use a begin end block with rescue clause:

begin
  str = ...
  i = Integer(str)

  i.times do |j|
    puts j
  end
rescue ArgumentError
  puts "Not an int, doing something else"
end

Yes, there is a better way: You can use the $parse service in your directive to evaluate an expression in the context of the parent scope while binding certain identifiers in the expression to values visible only inside your directive:

$parse(attributes.callback)(scope.$parent, { arg2: yourSecondArgument });

Add this line to the link function of the directive where you can access the directive's attributes.

Your callback attribute may then be set like callback = "callback(item.id, arg2)" because arg2 is bound to yourSecondArgument by the $parse service inside the directive. Directives like ng-click let you access the click event via the $event identifier inside the expression passed to the directive by using exactly this mechanism.

Note that you do not have to make callback a member of your isolated scope with this solution.

try this

single function for all radio have class "radio-button"

work in chrome and FF

$('.radio-button').on("click", function(event){_x000D_
  $('.radio-button').prop('checked', false);_x000D_
  $(this).prop('checked', true);_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>_x000D_
<input type='radio' class='radio-button' name='re'>_x000D_
<input type='radio'  class='radio-button' name='re'>_x000D_
<input type='radio'  class='radio-button' name='re'>

Another way: add windowNoTitle and windowFullscreen attributes directly to the theme (you can find styles.xml file in res/values/ directory):

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
</style>

in the manifest file, in application specify your theme

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

Use this when if satisfies

do

return true;

Something like this:

setUsers = function (data) {
    for (k in data) {
        user[k] = data[k];
    }
}

I often find convenient, inside my scripts, to define an iterable function. (Now incorporates Alfe's suggested simplification):

import collections

def iterable(obj):
    return isinstance(obj, collections.Iterable):

so you can test if any object is iterable in the very readable form

if iterable(obj):
    # act on iterable
else:
    # not iterable

as you would do with thecallable function

EDIT: if you have numpy installed, you can simply do: from numpy import iterable, which is simply something like

def iterable(obj):
    try: iter(obj)
    except: return False
    return True

If you do not have numpy, you can simply implement this code, or the one above.

int *arr1[5]

In this declaration, arr1 is an array of 5 pointers to integers. Reason: Square brackets have higher precedence over * (dereferncing operator). And in this type, number of rows are fixed (5 here), but number of columns is variable.

int (*arr2)[5]

In this declaration, arr2 is a pointer to an integer array of 5 elements. Reason: Here, () brackets have higher precedence than []. And in this type, number of rows is variable, but the number of columns is fixed (5 here).

Below is the configuration in Maven software by default in MAVEN_HOME\conf\settings.xml.

<settings>
  <!-- localRepository
   | The path to the local repository maven will use to store artifacts.

   | Default: ~/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>

Add the below line under this configuration, will fulfill the requirement.

<localRepository>custom_path</localRepository>

Ex: <localRepository>D:/MYNAME/settings/.m2/repository</localRepository>

for me i found some solutions: it is a working solution

Mozilla's MDN suggests something like the following [source]:

 p {
  width: intrinsic;           /* Safari/WebKit uses a non-standard name */
  width: -moz-max-content;    /* Firefox/Gecko */
  width: -webkit-max-content; /* Chrome */
}

Just add:

import os

in the beginning, before:

from settings import PROJECT_ROOT

This will import the python's module os, which apparently is used later in the code of your module without being imported.

You would simply do this:

SELECT (end_time - start_time) FROM t; -- return in Millisecond
SELECT (end_time - start_time)/1000 FROM t; -- return in Second

you can use AlertDialog as ProgressDialog refer below code for the ProgressDialog. This function you need to call whenever you show a progress dialog.

Code:

    public void setProgressDialog() {

    int llPadding = 30;
    LinearLayout ll = new LinearLayout(this);
    ll.setOrientation(LinearLayout.HORIZONTAL);
    ll.setPadding(llPadding, llPadding, llPadding, llPadding);
    ll.setGravity(Gravity.CENTER);
    LinearLayout.LayoutParams llParam = new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT);
    llParam.gravity = Gravity.CENTER;
    ll.setLayoutParams(llParam);

    ProgressBar progressBar = new ProgressBar(this);
    progressBar.setIndeterminate(true);
    progressBar.setPadding(0, 0, llPadding, 0);
    progressBar.setLayoutParams(llParam);

    llParam = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);
    llParam.gravity = Gravity.CENTER;
    TextView tvText = new TextView(this);
    tvText.setText("Loading ...");
    tvText.setTextColor(Color.parseColor("#000000"));
    tvText.setTextSize(20);
    tvText.setLayoutParams(llParam);

    ll.addView(progressBar);
    ll.addView(tvText);

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setCancelable(true);
    builder.setView(ll);

    AlertDialog dialog = builder.create();
    dialog.show();
    Window window = dialog.getWindow();
    if (window != null) {
        WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
        layoutParams.copyFrom(dialog.getWindow().getAttributes());
        layoutParams.width = LinearLayout.LayoutParams.WRAP_CONTENT;
        layoutParams.height = LinearLayout.LayoutParams.WRAP_CONTENT;
        dialog.getWindow().setAttributes(layoutParams);
    }
}

Output:

Is it possible to add onclick to a div and have it occur if any area of the div is clicked.

Yes … although it should be done with caution. Make sure there is some mechanism that allows keyboard access. Build on things that work

If yes then why is the onclick method not going through to my div.

You are assigning a string where a function is expected.

divTag.onclick = printWorking;

There are nicer ways to assign event handlers though, although older versions of Internet Explorer are sufficiently different that you should use a library to abstract it. There are plenty of very small event libraries and every major library jQuery) has event handling functionality.

That said, now it is 2019, older versions of Internet Explorer no longer exist in practice so you can go direct to addEventListener

I don't know what the .tex extension on your file means. If we are saying that it is any file with any extension you have several methods of reading it.

I have to assume you are using windows because you have mentioned notepad++.

1. Use notepad++. Right click on the file and choose "edit with notepad++"

2. Use notepad Change the filename extension to .txt and double click the file.

3. Use command prompt. Open the folder that your file is in. Hold down shift and right click. (not on the file, but in the folder that the file is in.) Choose "open command window here" from the command prompt type: "type filename.tex"

If these don't work, I would need more detail as to how they are not working. Errors that you may be getting or what you may expect to be in the file might help.

You cannot mix JS and PHP that way, PHP is rendered before the page is sent to the browser (i.e. before the JS is run)

You can use window.location to change your current page.

$('.entry a:first').click(function() {
    window.location = "http://google.ca";
});

If you have Pillow installed with scipy and it is still giving you error then check your scipy version because it has been removed from scipy since 1.3.0rc1.

rather install scipy 1.1.0 by :

pip install scipy==1.1.0

check https://github.com/scipy/scipy/issues/6212

The method imread in scipy.misc requires the forked package of PIL named Pillow. If you are having problem installing the right version of PIL try using imread in other packages:

from matplotlib.pyplot import imread
im = imread(image.png)

To read jpg images without PIL use:

import cv2 as cv
im = cv.imread(image.jpg)

You can try from scipy.misc.pilutil import imread instead of from scipy.misc import imread

Please check the GitHub page : https://github.com/amueller/mglearn/issues/2 for more details.

Maybe it helps someone, but I had the same issue and it was due to a lack of storage space caused by a log getting way too big.

Hope it helps someone! :)

git clone --branch {branch-name} {repo-URI}

Example:

git clone --branch dev https://github.com/ann/cleaningmachine.git

• dev: This is the {branch-name}
• https://github.com/ann/cleaningmachine.git: This is the {repo-URI}

You can also use this trick: replace

$("#topbar").click(function(){

by

$(document).on("click", "#topbar", function(){

This will bind an event on a not loaded yet object... ;)

For Apache 2.4, you would use the Require IP directive. So to only allow machines from the 192.168.0.0/24 network (range 192.168.0.0 - 192.168.0.255)

<VirtualHost *:80>
    <Location />
      Require ip 192.168.0.0/24
    </Location>
    ...
</VirtualHost>

And if you just want the localhost machine to have access, then there's a special Require local directive.

The local provider allows access to the server if any of the following conditions is true:

• the client address matches 127.0.0.0/8
• the client address is ::1
• both the client and the server address of the connection are the same

This allows a convenient way to match connections that originate from the local host:

<VirtualHost *:80>
    <Location />
      Require local
    </Location>
    ...
</VirtualHost>

It is about string concatenation performance. It's potentially significant if your have dense logging statements.

(Prior to SLF4J 1.7) But only two parameters are possible

Because the vast majority of logging statements have 2 or fewer parameters, so SLF4J API up to version 1.6 covers (only) the majority of use cases. The API designers have provided overloaded methods with varargs parameters since API version 1.7.

For those cases where you need more than 2 and you're stuck with pre-1.7 SLF4J, then just use either string concatenation or new Object[] { param1, param2, param3, ... }. There should be few enough of them that the performance is not as important.

You have to call close() on the GZIPOutputStream before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush() probably won't help ... though calling finish() instead of close() should work. Look at the javadocs.)

Here's the correct code (in Java);

package test;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

public class GZipTest {

    public static void main(String[] args) throws
                FileNotFoundException, IOException {
        String name = "/tmp/test";
        GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
        gz.write(10);
        gz.close();       // Remove this to reproduce the reported bug
        System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
    }

Double-check that you haven't enabled backface-visibility on any of the containing elements, as that will wreck position: fixed. For me, I was using a CSS3 animation library...

1. Probably you're using PlayServices of version 9.6.0. Then you should update it, it's library's bug. More info here.

OR

2. Add

   <uses-permission android:name="android.permission.READ_PHONE_STATE" tools:node="remove" />

to your manifest file.

Very easily done with Post build task plugin.

Here's a function to pretty up your json: pretty_json

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html> 

Check the php.ini

ini_set('max_execution_time', 300); //300 seconds = 5 minutes

ini_set('max_execution_time', 0); //0=NOLIMIT

Use print_r:

$myText = print_r($myVar,true);

You can also use it like:

$myText = print_r($myVar,true)."foo bar";

This will set $myText to a string, like:

array (
  0 => '11',
)foo bar

Use var_export to get a little bit more info (with types of variable,...):

$myText = var_export($myVar,true);

Solution with StringBuilder:

value = new StringBuilder()
                .append(value.substring(0, 1).toUpperCase())
                .append(value.substring(1))
                .toString();

Inspired by Eric's answer, here is my solution to this problem for selenium 3.7.0. Compared with the solution at http://tarunlalwani.com/post/reusing-existing-browser-session-selenium/, the advantage is that there won't be a blank browser window each time I connect to the existing session.

Update The currently suggested way to start a Task is simply using Task.Run()

Task.Run(() => foo());

Note that this method is described as the best way to start a task see here

Previous answer

I like the Task Factory from System.Threading.Tasks. You can do something like this:

Task.Factory.StartNew(() => 
{
    // Whatever code you want in your thread
});

Note that the task factory gives you additional convenience options like ContinueWith:

Task.Factory.StartNew(() => {}).ContinueWith((result) => 
{
    // Whatever code should be executed after the newly started thread.
});

Also note that a task is a slightly different concept than threads. They nicely fit with the async/await keywords, see here.

if by .add you mean .append, then the result is the same if #myDiv is empty.

is the performance the same? dont know.

.html(x) ends up doing the same thing as .empty().append(x)

You can set its before and after to force a constant width-to-height ratio

HTML:

<div class="squared"></div>

CSS:

.squared {
  background: #333;
  width: 300px; 
}
.squared::before {
  content: '';
  padding-top: 100%;
  float: left;
}
.squared::after {
  content: '';
  display: block;
  clear: both;
}

For example you want to find a mean of each column in matrix. Let's create the following matrix

mat2 = np.array([1,5,6,7,3,0,3,5,9,10,8,0], dtype=np.float64).reshape(3, 4)

The function for mean is

def my_mean(x):
    return sum(x)/len(x)

To do what is needed and store result in colon vector 'results'

results = np.zeros(4)
for i in range(0, 4):
    mat2[:, i] = my_mean(mat2[:, i])

results = mat2[1,:]      

The results are: array([4.33333333, 5. , 5.66666667, 4. ])

The easiest way:

Category[] category = Category.values();
for (int i = 0; i < cat.length; i++) {
     System.out.println(i  + " - " + category[i]);
}

Where Category is Enum name

std::string stringify(double x)
 {
   std::ostringstream o;
   if (!(o << x))
     throw BadConversion("stringify(double)");
   return o.str();
 }

C++ FAQ: http://www.parashift.com/c++-faq-lite/misc-technical-issues.html#faq-39.1

One option is to place your properties file in the src/ directory of your project. This will copy it to the "classes" (along with your .class files) at build time. I often do this for web projects.

I know, the question is very old, but I found a nice solution.

UIBarButtonItem *barButton = [[UIBarButtonItem alloc] init];
barButton.title = @"Custom Title";
self.navigationController.navigationBar.topItem.backBarButtonItem = barButton;

Works from childView! Tested with iOS 7.

I know this is an old post, with a lot of changes since 2017, but I have found that I can close my current tab/window with:

onClick="javascript:window.close('','_parent','');", now in 2019.  

Not tested, but you can do something like this:

Create Function dbo.AlphasOnly(@s as varchar(max)) Returns varchar(max) As
Begin
  Declare @Pos int = 1
  Declare @Ret varchar(max) = null
  If @s Is Not Null
  Begin
    Set @Ret = ''
    While @Pos <= Len(@s)
    Begin
      If SubString(@s, @Pos, 1) Like '[A-Za-z]'
      Begin
        Set @Ret = @Ret + SubString(@s, @Pos, 1)
      End
      Set @Pos = @Pos + 1
    End
  End
  Return @Ret
End

The key is to use this as a computed column and index it. It doesn't really matter how fast you make this function if the database has to execute it against every row in your large table every time you run the query.

I had the same error message when trying to run a Python script -- this was not @Warpspace's intended use case (see other comments), but this was among the top hits to my search, so maybe somebody will find it useful.

In my case it was the DOS line endings (\r\n instead of \n) that the shebang line (#!/usr/bin/env python) would trip over. A simple dos2unix myfile.py fixed it.

(np.where(np.isnan(A)))[0].shape[0] will be greater than 0 if A contains at least one element of nan, A could be an n x m matrix.

Example:

import numpy as np

A = np.array([1,2,4,np.nan])

if (np.where(np.isnan(A)))[0].shape[0]: 
    print "A contains nan"
else:
    print "A does not contain nan"

If your dictionary is Int to String you can do simply:

dict[3] = "efg"

If you mean adding elements to the value of the dictionary a possible solution:

var dict = Dictionary<String, Array<Int>>()

dict["key"]! += [1]
dict["key"]!.append(1)
dict["key"]?.append(1)

I have had the same issue in OSX. It can be fixed by running Disk Utilities to Repair Permissions. I agree with Peter Nixey: in my case it is caused when my 3G dongle installs or reinstalls its driver. Repairing Permissions afterward fixes the issue.

If I'm understanding you correctly, you should be able to do this in one query, joining table1 and table2 together:

INSERT INTO table3 { name, age, sex, city, id, number}
SELECT p.name, p.age, p.sex, p.city, p.id, c.number
FROM table1 p
INNER JOIN table2 c ON c.Id = p.Id

no need to that, tomcat naturally extract the war file into a folder of the same name. you simply modify the desired file inside that folder (including .xml configuration files), that's all. technically no need to restart tomcat after applying the modifications

Add a style = color:black !important; in your input type.

You could wrap the work in a function and assign it to the Object prototype. Maybe use the fluent interface style to make multiple renames flow.

Object.prototype.renameProperty = function (oldName, newName) {
     // Do nothing if the names are the same
     if (oldName === newName) {
         return this;
     }
    // Check for the old property name to avoid a ReferenceError in strict mode.
    if (this.hasOwnProperty(oldName)) {
        this[newName] = this[oldName];
        delete this[oldName];
    }
    return this;
};

ECMAScript 5 Specific

I wish the syntax wasn't this complex but it is definitely nice having more control.

Object.defineProperty(
    Object.prototype, 
    'renameProperty',
    {
        writable : false, // Cannot alter this property
        enumerable : false, // Will not show up in a for-in loop.
        configurable : false, // Cannot be deleted via the delete operator
        value : function (oldName, newName) {
            // Do nothing if the names are the same
            if (oldName === newName) {
                return this;
            }
            // Check for the old property name to 
            // avoid a ReferenceError in strict mode.
            if (this.hasOwnProperty(oldName)) {
                this[newName] = this[oldName];
                delete this[oldName];
            }
            return this;
        }
    }
);

If you use JDK version from 9+, you should select

Then, select @argfile (Java 9+) as in the image below. Please try it. Good luck friends.

I have created, yet another one, function for this purpose:

function dateDiff(date) {
    date = date.split('-');
    var today = new Date();
    var year = today.getFullYear();
    var month = today.getMonth() + 1;
    var day = today.getDate();
    var yy = parseInt(date[0]);
    var mm = parseInt(date[1]);
    var dd = parseInt(date[2]);
    var years, months, days;
    // months
    months = month - mm;
    if (day < dd) {
        months = months - 1;
    }
    // years
    years = year - yy;
    if (month * 100 + day < mm * 100 + dd) {
        years = years - 1;
        months = months + 12;
    }
    // days
    days = Math.floor((today.getTime() - (new Date(yy + years, mm + months - 1, dd)).getTime()) / (24 * 60 * 60 * 1000));
    //
    return {years: years, months: months, days: days};
}

Doesn't require any 3rd party libraries. Takes one argument -- date in YYYY-MM-DD format.

By default session object is available on jsp page(implicit object). It will not available in normal POJO java class. You can get the reference of HttpSession object on Servelt by using HttpServletRequest

HttpSession s=request.getSession()
s.setAttribute("name","value");

You can get session on an ActionSupport based Action POJO class as follows

 ActionContext ctx= ActionContext.getContext();
   Map m=ctx.getSession();
   m.put("name", value);

look at: http://ohmjavaclasses.blogspot.com/2011/12/access-session-in-action-class-struts2.html

Try:

source `which virtualenvwrapper.sh`

The backticks are command substitution - they take whatever the program prints out and put it in the expression. In this case "which" checks the $PATH to find virtualenvwrapper.sh and outputs the path to it. The script is then read by the shell via 'source'.

If you want this to happen every time you restart your shell, it's probably better to grab the output from the "which" command first, and then put the "source" line in your shell, something like this:

echo "source /path/to/virtualenvwrapper.sh" >> ~/.profile

^ This may differ slightly based on your shell. Also, be careful not to use the a single > as this will truncate your ~/.profile :-o

A quick and easy solution for interactive work is to copy-and-paste the text by loading the data from the clipboard.

Select the content of the string with your mouse:

In the Python shell use read_clipboard()

>>> pd.read_clipboard()
  col1;col2;col3
0       1;4.4;99
1      2;4.5;200
2       3;4.7;65
3      4;3.2;140

Use the appropriate separator:

>>> pd.read_clipboard(sep=';')
   col1  col2  col3
0     1   4.4    99
1     2   4.5   200
2     3   4.7    65
3     4   3.2   140

>>> df = pd.read_clipboard(sep=';') # save to dataframe

Finding all foreign keys

SELECT src.name, srcCol.name, dst.name, dstCol.name

        AND fk.parent_object_id = srcCol.[object_id]

    INNER JOIN sys.tables dst ON dst.[object_id] = fk.[referenced_object_id]
    INNER JOIN sys.columns dstCol ON fk.referenced_column_id = dstCol.[column_id] 
        AND fk.[referenced_object_id] = dstCol.[object_id]

I've been stuck with the same issue, and the preceding answer did not help me (albeit well written).

The solution is here : check your /etc/redis/redis.conf, and make sure to change the default

bind 127.0.0.1

to

bind 0.0.0.0

Then restart your service (service redis-server restart)

You can then now check that redis is listening on non-local interface with

redis-cli -h 192.168.x.x ping

(replace 192.168.x.x with your IP adress)

Important note : as several users stated, it is not safe to set this on a server which is exposed to the Internet. You should be certain that you redis is protected with any means that fits your needs.

Daniel Hilgarth's answer above leads to a System.NotSupported exception With Entity-Framework. With Entity-Framework, it has to be:

table1.GroupBy(x => x.Text).Select(x => x.FirstOrDefault());

If your dictionary is not nested, you could make a frozenset with the dict's items and use hash():

hash(frozenset(my_dict.items()))

This is much less computationally intensive than generating the JSON string or representation of the dictionary.

UPDATE: Please see the comments below, why this approach might not produce a stable result.

In addition to the answer of @Charles-Duffy, you can use winpty directly without installing/downloading anything extra. Just run winpty c:/Python27/python.exe. The utility winpty.exe can be found at Git\usr\bin. I'm using Git for Windows v2.7.1

The prebuilt binaries from @Charles-Duffy is version 0.1.1(according to the file name), while the included one is 0.2.2

I'm wondering whether you meant "recursive". Here is a simple example of a recursive function to compute the factorial function:

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n - 1)

The two key elements of a recursive algorithm are:

• The termination condition: n == 0
• The reduction step where the function calls itself with a smaller number each time: factorial(n - 1)

v-model
it is two way data binding, it is used to bind html input element when you change input value then bounded data will be change.

v-model is used only for HTML input elements

ex: <input type="text" v-model="name" > 

v-bind
it is one way data binding,means you can only bind data to input element but can't change bounded data changing input element. v-bind is used to bind html attribute
ex:
<input type="text" v-bind:class="abc" v-bind:value="">

<a v-bind:href="home/abc" > click me </a>

It happens that none of the above methods work. Key binding is proper, but tool tip simply doesn't show in any case, neither as completion help or on demand.

To fix it just go to Tools\Text Editor\C# (or all languages) and check the 'Parameter Information'. Now it should work

There is an another option to insert data into table ..

insert into tablename values(&column_name1,&column_name2,&column_name3);

it will open another window for inserting the data value..

It works.

I use char 'f', 'm' and 'u' because I surmise the gender from name, voice and conversation, and sometimes don't know the gender. The final determination is their opinion.

It really depends how well you know the person and whether your criteria is physical form or personal identity. A psychologist might need additional options - cross to female, cross to male, trans to female, trans to male, hermaphrodite and undecided. With 9 options, not clearly defined by a single character, I might go with Hugo's advice of tiny integer.

The name property is marked as protected. This was added in TypeScript 1.3 and is now firmly established.

The makeSound method is marked as abstract, as is the class. You cannot directly instantiate an Animal now, because it is abstract. This is part of TypeScript 1.6, which is now officially live.

abstract class Animal {
    constructor(protected name: string) { }

    abstract makeSound(input : string) : string;

    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    constructor(name: string) { super(name); }

    makeSound(input : string) : string {
        return "sssss"+input;
    }

    move() {
        alert("Slithering...");
        super.move(5);
    }
}

The old way of mimicking an abstract method was to throw an error if anyone used it. You shouldn't need to do this any more once TypeScript 1.6 lands in your project:

class Animal {
    constructor(public name) { }
    makeSound(input : string) : string {
        throw new Error('This method is abstract');
    }
    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    constructor(name) { super(name); }
    makeSound(input : string) : string {
        return "sssss"+input;
    }
    move() {
        alert("Slithering...");
        super.move(5);
    }
}

Suppose you were only allowed to use array then you could find the size of 2-d array by the following way.

  int ary[][5] = { {1, 2, 3, 4, 5},
                   {6, 7, 8, 9, 0}
                 };

  int rows =  sizeof ary / sizeof ary[0]; // 2 rows  

  int cols = sizeof ary[0] / sizeof(int); // 5 cols

I use:

Imports System.IO
Dim strPath as String=Directory.GetCurrentDirectory

please set dataType config property in your ajax call and give it another try!

another point is you are using ajax call setup configuration properties as string and it is wrong as reference site

$.ajax({

    url : 'http://voicebunny.comeze.com/index.php',
    type : 'GET',
    data : {
        'numberOfWords' : 10
    },
    dataType:'json',
    success : function(data) {              
        alert('Data: '+data);
    },
    error : function(request,error)
    {
        alert("Request: "+JSON.stringify(request));
    }
});

I hope be helpful!

In my case for Swift 5, I added these lines:

override func viewDidAppear(_ animated: Bool) {
    navigationController?.navigationBar.barStyle = .black
}

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

A HandlerInterceptor gives you more fine-grained control than a filter, because you have access to the actual target "handler" - this means that whatever action you perform can vary depending on what the request is actually doing (whereas the servlet filter is generically applied to all requests - only able to take into account the parameters of each request). The handlerInterceptor also provides 3 different methods, so that you can apply behavior prior to calling a handler, after the handler has completed but prior to view rendering (where you may even bypass view rendering altogether), or after the view itself has been rendered. Also, you can set up different interceptors for different groups of handlers - the interceptors are configured on the handlerMapping, and there may be multiple handlerMappings.

Therefore, if you have a need to do something completely generic (e.g. log all requests), then a filter is sufficient - but if the behavior depends on the target handler or you want to do something between the request handling and view rendering, then the HandlerInterceptor provides that flexibility.

Super simple and readable, here's how you create a local proxy server to a local HTTP server with just Node.js (tested on v8.1.0). I've found it particular useful for integration testing so here's my share:

/**
 * Once this is running open your browser and hit http://localhost
 * You'll see that the request hits the proxy and you get the HTML back
 */

'use strict';

const net = require('net');
const http = require('http');

const PROXY_PORT = 80;
const HTTP_SERVER_PORT = 8080;

let proxy = net.createServer(socket => {
    socket.on('data', message => {
        console.log('---PROXY- got message', message.toString());

        let serviceSocket = new net.Socket();

        serviceSocket.connect(HTTP_SERVER_PORT, 'localhost', () => {
            console.log('---PROXY- Sending message to server');
            serviceSocket.write(message);
        });

        serviceSocket.on('data', data => {
            console.log('---PROXY- Receiving message from server', data.toString();
            socket.write(data);
        });
    });
});

let httpServer = http.createServer((req, res) => {
    switch (req.url) {
        case '/':
            res.writeHead(200, {'Content-Type': 'text/html'});
            res.end('<html><body><p>Ciao!</p></body></html>');
            break;
        default:
            res.writeHead(404, {'Content-Type': 'text/plain'});
            res.end('404 Not Found');
    }
});

proxy.listen(PROXY_PORT);
httpServer.listen(HTTP_SERVER_PORT);

Would not \\(.*?\\) work? That is the non-greedy syntax.

JQUery has a .parents() method for moving up the DOM tree you can start there.

If you're interested in doing this a more semantic way I don't think using the REL attribute on a button is the best way to semantically define "this is the answer" in your code. I'd recommend something along these lines:

<p id="question1">
    <label for="input1">Volume =</label> 
    <input type="text" name="userInput1" id="userInput1" />
    <button type="button">Check answer</button>
    <input type="hidden" id="answer1" name="answer1" value="3.93e-6" />
</p>

and

$("button").click(function () {
    var correctAnswer = $(this).parent().siblings("input[type=hidden]").val();
    var userAnswer = $(this).parent().siblings("input[type=text]").val();
    validate(userAnswer, correctAnswer);
    $("#messages").html(feedback);
});

Not quite sure how your validate and feedback are working, but you get the idea.

Very elegant solution you can achieve by using chain of Promises:

app.put('url', (req, res) => {

    const modelId = req.body.model_id;
    const newName = req.body.name;

    MyModel.findById(modelId).then((model) => {
        return Object.assign(model, {name: newName});
    }).then((model) => {
        return model.save();
    }).then((updatedModel) => {
        res.json({
            msg: 'model updated',
            updatedModel
        });
    }).catch((err) => {
        res.send(err);
    });
});

Yeah, use .match, rather than .search. The result from the .match call will return the actual string that was matched itself, but it can still be used as a boolean value.

var string = "Stackoverflow is the BEST";
var result = string.match(/best/i);
// result == 'BEST';

if (result){
    alert('Matched');
}

Using a regular expression like that is probably the tidiest and most obvious way to do that in JavaScript, but bear in mind it is a regular expression, and thus can contain regex metacharacters. If you want to take the string from elsewhere (eg, user input), or if you want to avoid having to escape a lot of metacharacters, then you're probably best using indexOf like this:

matchString = 'best';
// If the match string is coming from user input you could do
// matchString = userInput.toLowerCase() here.

if (string.toLowerCase().indexOf(matchString) != -1){
    alert('Matched');
}

To link to the file, do the same as any other page link:

<a href="...">link text</a>

To force things to download even if they have an embedded plugin (Windows + QuickTime = ugh), you can use this in your htaccess / apache2.conf:

AddType application/octet-stream EXTENSION

In .NET 4 you don't need the ToArray() call - string.Join is overloaded to accept IEnumerable<T> or just IEnumerable<string>.

There are potentially more efficient ways of doing it before .NET 4, but do you really need them? Is this actually a bottleneck in your code?

You could iterate over the list, work out the final size, allocate a StringBuilder of exactly the right size, then do the join yourself. That would avoid the extra array being built for little reason - but it wouldn't save much time and it would be a lot more code.

One problem,everyone will face that is to Install Poppler.My way is a tricky way,but will work efficiently.1st download Poppler here.Then Extract it add In the code section just add poppler_path=r'C:\Program Files\poppler-0.68.0\bin'(for eg.) like below

from pdf2image import convert_from_path
images = convert_from_path("mypdf.pdf", 500,poppler_path=r'C:\Program Files\poppler-0.68.0\bin')
for i, image in enumerate(images):
    fname = 'image'+str(i)+'.png'
    image.save(fname, "PNG")

Bootstrap or other grid system it doesn't always mean simpler and better. Inside your .container or .row (to keep your responsive layout) u can just create 5 divs (with class .col f.e.) and add css like this:
.col { width: 20%; float: left };

update: nowodays its better to use flexbox

Underscore has few methods to do this;

1. _.extend(destination, *sources)

Copy all of the properties in the source objects over to the destination object, and return the destination object.

_.extend(a, _.extend(b, c));
=> {"one" : 1, "two" : 2, "three" : 3, "four" : 4, "five" : 5 }

Or

_.extend(a, b);
=> {"one" : 1, "two" : 2, "three" : 3}
_.extend(a, c);
=> {"one" : 1, "two" : 2, "three" : 3, "four" : 4, "five" : 5 }

2. _.defaults(object, *defaults)

Fill in undefined properties in object with values from the defaults objects, and return the object.

_.defaults(a, _.defaults(b, c));
=> {"one" : 1, "two" : 2, "three" : 3, "four" : 4, "five" : 5 }

Or

_.defaults(a, b);
=> {"one" : 1, "two" : 2, "three" : 3}
_.defaults(a, c);
=> {"one" : 1, "two" : 2, "three" : 3, "four" : 4, "five" : 5 }

$('#test').attr('checked','checked');

$('#test').removeAttr('checked');

For my own project I wanted to flatten JSON objects in mongoDB dot notation and came up with a simple solution:

/**
 * Recursively flattens a JSON object using dot notation.
 *
 * NOTE: input must be an object as described by JSON spec. Arbitrary
 * JS objects (e.g. {a: () => 42}) may result in unexpected output.
 * MOREOVER, it removes keys with empty objects/arrays as value (see
 * examples bellow).
 *
 * @example
 * // returns {a:1, 'b.0.c': 2, 'b.0.d.e': 3, 'b.1': 4}
 * flatten({a: 1, b: [{c: 2, d: {e: 3}}, 4]})
 * // returns {a:1, 'b.0.c': 2, 'b.0.d.e.0': true, 'b.0.d.e.1': false, 'b.0.d.e.2.f': 1}
 * flatten({a: 1, b: [{c: 2, d: {e: [true, false, {f: 1}]}}]})
 * // return {a: 1}
 * flatten({a: 1, b: [], c: {}})
 *
 * @param obj item to be flattened
 * @param {Array.string} [prefix=[]] chain of prefix joined with a dot and prepended to key
 * @param {Object} [current={}] result of flatten during the recursion
 *
 * @see https://docs.mongodb.com/manual/core/document/#dot-notation
 */
function flatten (obj, prefix, current) {
  prefix = prefix || []
  current = current || {}

  // Remember kids, null is also an object!
  if (typeof (obj) === 'object' && obj !== null) {
    Object.keys(obj).forEach(key => {
      this.flatten(obj[key], prefix.concat(key), current)
    })
  } else {
    current[prefix.join('.')] = obj
  }

  return current
}

Features and/or caveats

• It only accepts JSON objects. So if you pass something like {a: () => {}} you might not get what you wanted!
• It removes empty arrays and objects. So this {a: {}, b: []} is flattened to {}.

Before installing libgtk2.0-dev and pkg-config or libqt4-dev. Make sure that you have uninstalled opencv. You can confirm this by running import cv2 on your python shell. If it fails, then install the needed packages and re-run cmake .

Here are some useful links:

You can have multiple identical hash keys; but only if you have a range key that varies. Think of it like file formats; you can have 2 files with the same name in the same folder as long as their format is different. If their format is the same, their name must be different. The same concept applies to DynamoDB's hash/range keys; just think of the hash as the name and the range as the format.

Also, I don't recall if they had these at the time of the OP (I don't believe they did), but they now offer Local Secondary Indexes.

My understanding of these is that it should now allow you to perform the desired queries without having to do a full scan. The downside is that these indexes have to be specified at table creation, and also (I believe) cannot be blank when creating an item. In addition, they require additional throughput (though typically not as much as a scan) and storage, so it's not a perfect solution, but a viable alternative, for some.

I do still recommend Mike Brant's answer as the preferred method of using DynamoDB, though; and use that method myself. In my case, I just have a central table with only a hash key as my ID, then secondary tables that have a hash and range that can be queried, then the item points the code to the central table's "item of interest", directly.

Additional data regarding the secondary indexes can be found in Amazon's DynamoDB documentation here for those interested.

Anyway, hopefully this will help anyone else that happens upon this thread.

Just came across the same problem and the null-coalescing operator with SelectSingleNode worked a treat, assigning null with string.Empty

 foreach (XmlNode txElement in txElements)
 {
     var txStatus = txElement.SelectSingleNode(".//ns:TxSts", nsmgr).InnerText ?? string.Empty;
     var endToEndId = txElement.SelectSingleNode(".//ns:OrgnlEndToEndId", nsmgr).InnerText ?? string.Empty;
     var paymentAmount = txElement.SelectSingleNode(".//ns:InstdAmt", nsmgr).InnerText ?? string.Empty;
     var paymentAmountCcy = txElement.SelectSingleNode(".//ns:InstdAmt", nsmgr).Attributes["Ccy"].Value ?? string.Empty;
     var clientId = txElement.SelectSingleNode(".//ns:OrgnlEndToEndId", nsmgr).InnerText ?? string.Empty;
     var bankSortCode = txElement.SelectSingleNode(".//ns:OrgnlEndToEndId", nsmgr).InnerText ?? string.Empty; 

     //TODO finish Object creation and Upsert DB
