Having unsigned in variable declaration is more useful for the programmers themselves - don't treat the variables as negative. As you've noticed, both -1 and 4294967295 have exact same bit representation for a 4 byte integer. It's all about how you want to treat or see them.

The statement unsigned int a = -1; is converting -1 in two's complement and assigning the bit representation in a. The printf() specifier x, d and u are showing how the bit representation stored in variable a looks like in different format.

width, height = map(int, input().split())
def rectanglePerimeter(width, height):
   return ((width + height)*2)
print(rectanglePerimeter(width, height))

Running it like this produces:

% echo "1 2" | test.py
6

I suspect IDLE is simply passing a single string to your script. The first input() is slurping the entire string. Notice what happens if you put some print statements in after the calls to input():

width = input()
print(width)
height = input()
print(height)

Running echo "1 2" | test.py produces

1 2
Traceback (most recent call last):
  File "/home/unutbu/pybin/test.py", line 5, in <module>
    height = input()
EOFError: EOF when reading a line

Notice the first print statement prints the entire string '1 2'. The second call to input() raises the EOFError (end-of-file error).

So a simple pipe such as the one I used only allows you to pass one string. Thus you can only call input() once. You must then process this string, split it on whitespace, and convert the string fragments to ints yourself. That is what

width, height = map(int, input().split())

does.

Note, there are other ways to pass input to your program. If you had run test.py in a terminal, then you could have typed 1 and 2 separately with no problem. Or, you could have written a program with pexpect to simulate a terminal, passing 1 and 2 programmatically. Or, you could use argparse to pass arguments on the command line, allowing you to call your program with

test.py 1 2

A server socket listens on a single port. All established client connections on that server are associated with that same listening port on the server side of the connection. An established connection is uniquely identified by the combination of client-side and server-side IP/Port pairs. Multiple connections on the same server can share the same server-side IP/Port pair as long as they are associated with different client-side IP/Port pairs, and the server would be able to handle as many clients as available system resources allow it to.

On the client-side, it is common practice for new outbound connections to use a random client-side port, in which case it is possible to run out of available ports if you make a lot of connections in a short amount of time.

To export the output to file on a continuous basis (here every five seconds) and save to a CSV file with the Unix date as the filename:

while ($true) {
     [int]$date = get-date -Uformat %s
     $exportlocation = New-Item -type file -path "c:\$date.csv"
     Get-Counter -Counter "\Processor(_Total)\% Processor Time" | % {$_} | Out-File $exportlocation
     start-sleep -s 5
}

Although there are some good answers for this question. I would like to give another answer here with several examples of loop.

• O(n): Time Complexity of a loop is considered as O(n) if the loop variables is incremented / decremented by a constant amount. For example following functions have O(n) time complexity.

  // Here c is a positive integer constant   
  for (int i = 1; i <= n; i += c) {  
      // some O(1) expressions
  }
  
  for (int i = n; i > 0; i -= c) {
      // some O(1) expressions
  }
  

• O(n^c): Time complexity of nested loops is equal to the number of times the innermost statement is executed. For example the following sample loops have O(n^2) time complexity

  for (int i = 1; i <=n; i += c) {
     for (int j = 1; j <=n; j += c) {
        // some O(1) expressions
     }
  }
  
  for (int i = n; i > 0; i += c) {
     for (int j = i+1; j <=n; j += c) {
        // some O(1) expressions
  }
  

  For example Selection sort and Insertion Sort have O(n^2) time complexity.

• O(Logn) Time Complexity of a loop is considered as O(Logn) if the loop variables is divided / multiplied by a constant amount.

  for (int i = 1; i <=n; i *= c) {
     // some O(1) expressions
  }
  for (int i = n; i > 0; i /= c) {
     // some O(1) expressions
  }
  

  For example Binary Search has O(Logn) time complexity.

• O(LogLogn) Time Complexity of a loop is considered as O(LogLogn) if the loop variables is reduced / increased exponentially by a constant amount.

  // Here c is a constant greater than 1   
  for (int i = 2; i <=n; i = pow(i, c)) { 
     // some O(1) expressions
  }
  //Here fun is sqrt or cuberoot or any other constant root
  for (int i = n; i > 0; i = fun(i)) { 
     // some O(1) expressions
  }
  

One example of time complexity analysis

int fun(int n)
{    
    for (int i = 1; i <= n; i++)
    {
        for (int j = 1; j < n; j += i)
        {
            // Some O(1) task
        }
    }    
}

Analysis:

For i = 1, the inner loop is executed n times. For i = 2, the inner loop is executed approximately n/2 times. For i = 3, the inner loop is executed approximately n/3 times. For i = 4, the inner loop is executed approximately n/4 times. ……………………………………………………. For i = n, the inner loop is executed approximately n/n times.

So the total time complexity of the above algorithm is (n + n/2 + n/3 + … + n/n), Which becomes n * (1/1 + 1/2 + 1/3 + … + 1/n)

The important thing about series (1/1 + 1/2 + 1/3 + … + 1/n) is equal to O(Logn). So the time complexity of the above code is O(nLogn).

TLS client certificates are not sent in HTTP headers. They are transmitted by the client as part of the TLS handshake, and the server will typically check the validity of the certificate during the handshake as well.

If the certificate is accepted, most web servers can be configured to add headers for transmitting the certificate or information contained on the certificate to the application. Environment variables are populated with certificate information in Apache and Nginx which can be used in other directives for setting headers.

As an example of this approach, the following Nginx config snippet will validate a client certificate, and then set the SSL_CLIENT_CERT header to pass the entire certificate to the application. This will only be set when then certificate was successfully validated, so the application can then parse the certificate and rely on the information it bears.

server {
    listen 443 ssl;
    server_name example.com;
    ssl_certificate /path/to/chainedcert.pem;  # server certificate
    ssl_certificate_key /path/to/key;          # server key

    ssl_client_certificate /path/to/ca.pem;    # client CA
    ssl_verify_client on;
    proxy_set_header SSL_CLIENT_CERT $ssl_client_cert;

    location / {
        proxy_pass http://localhost:3000;
    }
}

if using TypeScript, you can use the spread operator (...)

var json = {...json1,...json2} 

You can use this to count number of NA or blanks in every column

colSums(is.na(data_set_name)|data_set_name == '')

This is the way i use it. It's very simple and work very well.. Ionic html:

Result of the code

I believe this would be somewhere close.

INSERT INTO Files

SELECT 1, * FROM OPENROWSET(BULK N'C:\Image.jpg', SINGLE_BLOB) rs

Something to note, the above runs in SQL Server 2005 and SQL Server 2008 with the data type as varbinary(max). It was not tested with image as data type.

Redux can't return a function instead of an action. It's just a fact. That's why people use Thunk. Read these 14 lines of code to see how it allows the async cycle to work with some added function layering:

function createThunkMiddleware(extraArgument) {
  return ({ dispatch, getState }) => (next) => (action) => {
    if (typeof action === 'function') {
      return action(dispatch, getState, extraArgument);
    }

    return next(action);
  };
}

const thunk = createThunkMiddleware();
thunk.withExtraArgument = createThunkMiddleware;

export default thunk;

https://github.com/reduxjs/redux-thunk

You could try

DF <- data.frame("a" = as.character(0:5),
                 "b" = paste(0:5, ".1", sep = ""),
                 "c" = letters[1:6],
                 stringsAsFactors = FALSE)

# Check columns classes
sapply(DF, class)

#           a           b           c 
# "character" "character" "character" 

cols.num <- c("a","b")
DF[cols.num] <- sapply(DF[cols.num],as.numeric)
sapply(DF, class)

#          a           b           c 
#  "numeric"   "numeric" "character"

If you are using ASP.NET Core MVC project. This error message can be shown then you have the correct cshtml file in your Views folder but the action is missing in your controller.

Adding the missing action to the controller will fix it.

You need to move type parameter to the method level to indicate that you have a generic method rather than generic class:

public class ArrayUtils {
    public static <T> E[] appendToArray(E[] array, E item) {
        E[] result = (E[])new Object[array.length+1];
        result[array.length] = item;
        return result;
    }
}

This also happened to me but using Dynamic Features. I already had Java 8 compatibility enabled in the app module but I had to add this compatibility lines to the Dynamic Feature module and then it worked.

If you wish to create a pdf from php, pdflib will help you (as some others suggested).

Else, if you want to convert an HTML page to PDF via PHP, you'll find a little trouble outta here.. For 3 years I've been trying to do it as best as I can.

So, the options I know are:

DOMPDF : php class that wraps the html and builds the pdf. Works good, customizable (if you know php), based on pdflib, if I remember right it takes even some CSS. Bad news: slow when the html is big or complex.

HTML2PS: same as DOMPDF, but this one converts first to a .ps (ghostscript) file, then, to whatever format you need (pdf, jpg, png). For me is little better than dompdf, but has the same speed problem.. but, better compatibility with CSS.

Those two are php classes, but if you can install some software on the server, and access it throught passthru() or system(), give a look to these too:

wkhtmltopdf: based on webkit (safari's wrapper), is really fast and powerful.. seems like this is the best one (atm) for converting html pages to pdf on the fly; taking only 2 seconds for a 3 page xHTML document with CSS2. It is a recent project, anyway, the google.code page is often updated.

htmldoc : This one is a tank, it never really stops/crashes.. the project looks dead since 2007, but anyway if you don't need CSS compatibility this can be nice for you.

or you can just

<script> 
document.write('<img src="/*picture_location_(you can just copy the picture and paste   it into the script)*\"')
document.getElementById('pic')
</script>
<div id="pic">
</div>

my result looks like this:

public static async Task<string> Upload(byte[] image)
{
     using (var client = new HttpClient())
     {
         using (var content =
             new MultipartFormDataContent("Upload----" + DateTime.Now.ToString(CultureInfo.InvariantCulture)))
         {
             content.Add(new StreamContent(new MemoryStream(image)), "bilddatei", "upload.jpg");

              using (
                 var message =
                     await client.PostAsync("http://www.directupload.net/index.php?mode=upload", content))
              {
                  var input = await message.Content.ReadAsStringAsync();

                  return !string.IsNullOrWhiteSpace(input) ? Regex.Match(input, @"http://\w*\.directupload\.net/images/\d*/\w*\.[a-z]{3}").Value : null;
              }
          }
     }
}

There is no operator, but there is a method.

Math.pow(2, 3) // 8.0

Math.pow(3, 2) // 9.0

FYI, a common mistake is to assume 2 ^ 3 is 2 to the 3rd power. It is not. The caret is a valid operator in Java (and similar languages), but it is binary xor.

Improved function "hex"

function hex(x){
    return isNaN(x) ? "00" : hexDigits[x >> 4] + hexDigits[x & 0xf];
    // or option without hexDigits array
    return (x >> 4).toString(16)+(x & 0xf).toString(16);
}

Add:

using System.Linq;

to the top of your file.

And then:

Car[] carList = ...
var carMake = 
    from item in carList
    where item.Model == "bmw" 
    select item.Make;

or if you prefer the fluent syntax:

var carMake = carList
    .Where(item => item.Model == "bmw")
    .Select(item => item.Make);

Things to pay attention to:

• The usage of item.Make in the select clause instead if s.Make as in your code.
• You have a whitespace between item and .Model in your where clause

Example JS Fiddle

Bullets take the color property of the list:

.listStyle {
    color: red;
}

Note if you want your list text to be a different colour, you have to wrap it in say, a p, for example:

.listStyle p {
    color: black;
}

Example HTML:

<ul class="listStyle">
    <li>
        <p><strong>View :</strong> blah blah.</p>
    </li>
    <li>
        <p><strong>View :</strong> blah blah.</p>
    </li>
</ul>

1) Add the following line to /etc/security/limits.conf

webuser hard nofile 64000

then login as webuser

su - webuser

2) Edit following two files for webuser

append .bashrc and .bash_profile file by running

echo "ulimit -n 64000" >> .bashrc ; echo "ulimit -n 64000" >> .bash_profile

3) Log out, then log back in and verify that the changes have been made correctly:

$ ulimit -a | grep open
open files                      (-n) 64000

Thats it and them boom, boom boom.

You can read your BufferedInputStream like this. It will read data till it reaches end of stream which is indicated by -1.

inputS = new BufferedInputStream(inBS);
byte[] buffer = new byte[1024];    //If you handle larger data use a bigger buffer size
int read;
while((read = inputS.read(buffer)) != -1) {
    System.out.println(read);
    // Your code to handle the data
}

To clone a repository and place it in a specified directory use "git clone [url] [directory]". For example

git clone https://github.com/ryanb/railscasts-episodes.git Rails

will create a directory named "Rails" and place it in the new directory. Click here for more information.

TL;DR:

Please refer to the glossary: hash() is used as a shortcut to comparing objects, an object is deemed hashable if it can be compared to other objects. that is why we use hash(). It's also used to access dict and set elements which are implemented as resizable hash tables in CPython.

Technical considerations

• usually comparing objects (which may involve several levels of recursion) is expensive.
• preferably, the hash() function is an order of magnitude (or several) less expensive.
• comparing two hashes is easier than comparing two objects, this is where the shortcut is.

If you read about how dictionaries are implemented, they use hash tables, which means deriving a key from an object is a corner stone for retrieving objects in dictionaries in O(1). That's however very dependent on your hash function to be collision-resistant. The worst case for getting an item in a dictionary is actually O(n).

On that note, mutable objects are usually not hashable. The hashable property means you can use an object as a key. If the hash value is used as a key and the contents of that same object change, then what should the hash function return? Is it the same key or a different one? It depends on how you define your hash function.

Learning by example:

Imagine we have this class:

>>> class Person(object):
...     def __init__(self, name, ssn, address):
...         self.name = name
...         self.ssn = ssn
...         self.address = address
...     def __hash__(self):
...         return hash(self.ssn)
...     def __eq__(self, other):
...         return self.ssn == other.ssn
... 

Please note: this is all based on the assumption that the SSN never changes for an individual (don't even know where to actually verify that fact from authoritative source).

And we have Bob:

>>> bob = Person('bob', '1111-222-333', None)

Bob goes to see a judge to change his name:

>>> jim = Person('jim bo', '1111-222-333', 'sf bay area')

This is what we know:

>>> bob == jim
True

But these are two different objects with different memory allocated, just like two different records of the same person:

>>> bob is jim
False

Now comes the part where hash() is handy:

>>> dmv_appointments = {}
>>> dmv_appointments[bob] = 'tomorrow'

Guess what:

>>> dmv_appointments[jim] #?
'tomorrow'

From two different records you are able to access the same information. Now try this:

>>> dmv_appointments[hash(jim)]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 9, in __eq__
AttributeError: 'int' object has no attribute 'ssn'
>>> hash(jim) == hash(hash(jim))
True

What just happened? That's a collision. Because hash(jim) == hash(hash(jim)) which are both integers btw, we need to compare the input of __getitem__ with all items that collide. The builtin int does not have an ssn attribute so it trips.

>>> del Person.__eq__
>>> dmv_appointments[bob]
'tomorrow'
>>> dmv_appointments[jim]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: <__main__.Person object at 0x7f611bd37110>

In this last example, I show that even with a collision, the comparison is performed, the objects are no longer equal, which means it successfully raises a KeyError.

As mentioned in all other answers, the keyword continue will skip to the end of the current iteration.

Additionally you can label your loop starts and then use continue [labelname]; or break [labelname]; to control what's going on in nested loops:

loop1: for (int i = 1; i < 10; i++) {
    loop2: for (int j = 1; j < 10; j++) {
        if (i + j == 10)
            continue loop1;

        System.out.print(j);
    }
    System.out.println();
}

Check whether the USERNAME is correct, for me a new USERNAME got created with my proxy extension.

With Python 3, the following code will format an Exception object exactly as would be obtained using traceback.format_exc():

import traceback

try: 
    method_that_can_raise_an_exception(params)
except Exception as ex:
    print(''.join(traceback.format_exception(etype=type(ex), value=ex, tb=ex.__traceback__)))

The advantage being that only the Exception object is needed (thanks to the recorded __traceback__ attribute), and can therefore be more easily passed as an argument to another function for further processing.

I think this say it all:

this alternative syntax is excellent for improving legibility (for both PHP and HTML!) in situations where you have a mix of them.

http://ca3.php.net/manual/en/control-structures.alternative-syntax.php

When mixing HTML an PHP the alternative sytnax is much easier to read. In normal PHP documents the traditional syntax should be used.

You can always use the ( <condition> ? <value if true> : <value if false> ) syntax (it's called the ternary operator - thanks to Mark for remining me :) ).

If <condition> is true, the statement would be evaluated as <value if true>. If not, it would be evaluated as <value if false>

For instance:

$fourteen = 14;
$twelve = 12;
echo "Fourteen is ".($fourteen > $twelve ? "more than" : "not more than")." twelve";

This is the same as:

$fourteen = 14;
$twelve = 12;
if($fourteen > 12) {
  echo "Fourteen is more than twelve";
}else{
  echo "Fourteen is not more than twelve";
}

A way to do this would be to set the color of the element to black, and then fade to the color of the background like this:

<style> 
p {
animation-name: example;
animation-duration: 2s;
}

@keyframes example {
from {color:black;}
to {color:white;}
}
</style>
<p>I am FADING!</p>

I hope this is what you needed!

pax> echo a.b.js | sed 's/\.[^.]*$//'
a.b
pax> echo a.b.js | sed 's/^.*\.//'
js

works fine, so you can just use:

pax> FILE=a.b.js
pax> NAME=$(echo "$FILE" | sed 's/\.[^.]*$//')
pax> EXTENSION=$(echo "$FILE" | sed 's/^.*\.//')
pax> echo $NAME
a.b
pax> echo $EXTENSION
js

The commands, by the way, work as follows.

The command for NAME substitutes a "." character followed by any number of non-"." characters up to the end of the line, with nothing (i.e., it removes everything from the final "." to the end of the line, inclusive). This is basically a non-greedy substitution using regex trickery.

The command for EXTENSION substitutes a any number of characters followed by a "." character at the start of the line, with nothing (i.e., it removes everything from the start of the line to the final dot, inclusive). This is a greedy substitution which is the default action.

• Changing Values:
  • array_map cannot change the values inside input array(s) while array_walk can; in particular, array_map never changes its arguments.
• Array Keys Access:
  • array_map cannot operate with the array keys, array_walk can.
• Return Value:
  • array_map returns a new array, array_walk only returns true. Hence, if you don't want to create an array as a result of traversing one array, you should use array_walk.
• Iterating Multiple Arrays:
  • array_map also can receive an arbitrary number of arrays and it can iterate over them in parallel, while array_walk operates only on one.
• Passing Arbitrary Data to Callback:
  • array_walk can receive an extra arbitrary parameter to pass to the callback. This mostly irrelevant since PHP 5.3 (when anonymous functions were introduced).
• Length of Returned Array:
  • The resulting array of array_map has the same length as that of the largest input array; array_walk does not return an array but at the same time it cannot alter the number of elements of original array; array_filter picks only a subset of the elements of the array according to a filtering function. It does preserve the keys.

Example:

<pre>
<?php

$origarray1 = array(2.4, 2.6, 3.5);
$origarray2 = array(2.4, 2.6, 3.5);

print_r(array_map('floor', $origarray1)); // $origarray1 stays the same

// changes $origarray2
array_walk($origarray2, function (&$v, $k) { $v = floor($v); }); 
print_r($origarray2);

// this is a more proper use of array_walk
array_walk($origarray1, function ($v, $k) { echo "$k => $v", "\n"; });

// array_map accepts several arrays
print_r(
    array_map(function ($a, $b) { return $a * $b; }, $origarray1, $origarray2)
);

// select only elements that are > 2.5
print_r(
    array_filter($origarray1, function ($a) { return $a > 2.5; })
);

?>
</pre>

All C++ compilers have one serious performance problem to deal with. Compiling C++ code is a long, slow process.

Compiling headers included on top of C++ files is a very long, slow process. Compiling the huge header structures that form part of Windows API and other large API libraries is a very, very long, slow process. To have to do it over, and over, and over for every single Cpp source file is a death knell.

This is not unique to Windows but an old problem faced by all compilers that have to compile against a large API like Windows.

The Microsoft compiler can ameliorate this problem with a simple trick called precompiled headers. The trick is pretty slick: although every CPP file can potentially and legally give a sligthly different meaning to the chain of header files included on top of each Cpp file (by things like having different macros #define'd in advance of the includes, or by including the headers in different order), that is most often not the case. Most of the time, we have dozens or hundreds of included files, but they all are intended to have the same meaning for all the Cpp files being compiled in your application.

The compiler can make huge time savings if it doesn't have to start to compile every Cpp file plus its dozens of includes literally from scratch every time.

The trick consists of designating a special header file as the starting point of all compilation chains, the so called 'precompiled header' file, which is commonly a file named stdafx.h simply for historical reasons.

Simply list all your big huge headers for your APIs in your stdafx.h file, in the appropriate order, and then start each of your CPP files at the very top with an #include "stdafx.h", before any meaningful content (just about the only thing allowed before is comments).

Under those conditions, instead of starting from scratch, the compiler starts compiling from the already saved results of compiling everything in stdafx.h.

I don't believe that this trick is unique to Microsoft compilers, nor do I think it was an original development.

For Microsoft compilers, the setting that controls the use of precompiled headers is controlled by a command line argument to the compiler: /Yu "stdafx.h". As you can imagine, the use of the stdafx.h file name is simply a convention; you can change the name if you so wish.

In Visual Studio 2010, this setting is controlled from the GUI via Right-clicking on a CPP Project, selecting 'Properties' and navigating to "Configuration Properties\C/C++\Precompiled Headers". For other versions of Visual Studio, the location in the GUI will be different.

Note that if you disable precompiled headers (or run your project through a tool that doesn't support them), it doesn't make your program illegal; it simply means that your tool will compile everything from scratch every time.

If you are creating a library with no Windows dependencies, you can easily comment out or remove #includes from the stdafx.h file. There is no need to remove the file per se, but clearly you may do so as well, by disabling the precompile header setting above.

I will explain the method i usally prefer:

First of all you need to take into consideration that for this method you will sacrifice memory with the aim of gaining computation speed. Second you need to have a the right to edit the table structure.

1) Add a field (i usually call it "digest") where you store all the data from the table.

The field will look like:

"n-n1-n2-n3-n4-n5-n6-n7-n8-n9" etc.. where n is a single word

I achieve this using a regular expression thar replaces " " with "-". This field is the result of all the table data "digested" in one sigle string.

2) Use the LIKE statement %keyword% on the digest field:

SELECT * FROM table WHERE digest LIKE %keyword%

you can even build a qUery with a little loop so you can search for multiple keywords at the same time looking like:

SELECT * FROM table WHERE 
 digest LIKE %keyword1% AND 
 digest LIKE %keyword2% AND 
 digest LIKE %keyword3% ... 

Alternative solution is to modify your current Visual Studio installation in the Visual Studio Installer

Win+R %ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vs_installer.exe

adding the Blend for Visual Studio SDK for .NET 'Individual component' under 'SDKs, libraries, and frameworks':

after adding this component System.Windows.Interactivity should appear in its regular location Add Reference/Assemblies/Extensions.

It appears this would only work for VS2017 or earlier. For later versions, please refer to other answers.

Perhaps something like this?

Thus, all info messages are written to server.log; by contrast, foo.log contains only com.example.foo messages, including debug-level messages.

Probably the easiest solution so far:

public static Bitmap cropCenter(Bitmap bmp) {
    int dimension = Math.min(bmp.getWidth(), bmp.getHeight());
    return ThumbnailUtils.extractThumbnail(bmp, dimension, dimension);
}

imports:

import android.media.ThumbnailUtils;
import java.lang.Math;
import android.graphics.Bitmap;

You can do it this way:

=IF(E9>21,"Text 1",IF(AND(E9>=5,E9<=21),"Test 2","Text 3"))

Note I assume you meant >= and <= here since your description skipped the values 5 and 21, but you can adjust these inequalities as needed.

Or you can do it this way:

=IF(E9>21,"Text 1",IF(E9<5,"Text 3","Text 2"))

You can always take the CTE, (Common Tabular Expression), approach.

;WITH updateCTE AS
(
    SELECT ID, TITLE 
    FROM HOLD_TABLE
    WHERE ID = 101
)

UPDATE updateCTE
SET TITLE = 'TEST';

To get a user's current location you need to declare:

let locationManager = CLLocationManager()

In viewDidLoad() you have to instantiate the CLLocationManager class, like so:

// Ask for Authorisation from the User.
self.locationManager.requestAlwaysAuthorization() 

// For use in foreground
self.locationManager.requestWhenInUseAuthorization()

if CLLocationManager.locationServicesEnabled() {
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
    locationManager.startUpdatingLocation()
}

Then in CLLocationManagerDelegate method you can get user's current location coordinates:

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    guard let locValue: CLLocationCoordinate2D = manager.location?.coordinate else { return }
    print("locations = \(locValue.latitude) \(locValue.longitude)")
}

In the info.plist you will have to add NSLocationAlwaysUsageDescription and your custom alert message like; AppName(Demo App) would like to use your current location.

If you haven't already created the project in Github, do so on that site. If memory serves, they display a page that tells you exactly how to get your existing code into your new repository. At the risk of oversimplification, though, you'd follow Veeti's instructions, then:

git remote add [name to use for remote] [private URI] # associate your local repository to the remote
git push [name of remote] master # push your repository to the remote

You can query with a regular expression:

db.users.find({"name": /m/});

If the string is coming from the user, maybe you want to escape the string before using it. This will prevent literal chars from the user to be interpreted as regex tokens.

For example, searching the string "A." will also match "AB" if not escaped. You can use a simple replace to escape your string before using it. I made it a function for reusing:

function textLike(str) {
  var escaped = str.replace(/[\-\[\]\/\{\}\(\)\*\+\?\.\\\^\$\|]/g, '\\$&');
  return new RegExp(escaped, 'i');
}

So now, the string becomes a case-insensitive pattern matching also the literal dot. Example:

>  textLike('A.');
<  /A\./i

Now we are ready to generate the regular expression on the go:

db.users.find({ "name": textLike("m") });

not really... I used

 <system.webServer>
     <httpProtocol allowKeepAlive="true" >
       <customHeaders>
         <add name="X-Frame-Options" value="*" />
       </customHeaders>
     </httpProtocol>
 </system.webServer>

I see what you are trying to ask and I think this is the simplest answer to what you are looking for, given you might not know how many key pairs your are being sent.

Simple Key Pair JSON structure

var data = {
    'XXXXXX' : '100.0',
    'YYYYYYY' : '200.0',
    'ZZZZZZZ' : '500.0',
}

Usage JavaScript code to access the key pairs

for (var key in data) 
  { if (!data.hasOwnProperty(key))
    { continue; } 
    console.log(key + ' -> ' +  data[key]);
  };

Console output should look like this

XXXXXX -> 100.0 
YYYYYYY -> 200.0 
ZZZZZZZ -> 500.0

Here is a JSFiddle to show how it works.

Just add the function reference to the $scope in the controller:

for example if you want the function MyFunction to work in ng-click just add to the controller:

app.controller("MyController", ["$scope", function($scope) {
   $scope.MyFunction = MyFunction;
}]);

try to use use include_onceor require_once instead of include or require

If you can get away with using Guava it is by far the simplest way to do it, and you don't have to reinvent the wheel:

final HashCode hashCode = Hashing.sha1().hashString(yourValue, Charset.defaultCharset());

You can then take the hashed value and get it as a byte[], as an int, or as a long.

No wrapping in a try catch, no shenanigans. And if you decide you want to use something other than SHA-1, Guava also supports sha256, sha 512, and a few I had never even heard about like adler32 and murmur3.

Your query translates to

SELECT * FROM table WHERE id='1' or id='2' or id='3' or id='4';

It will only return the results that match it.

One way of solving it avoiding the complexity would be, chaning the datatype to SET. Then you could use, FIND_IN_SET

SELECT * FROM table WHERE FIND_IN_SET('1', id);

Do this

    <% for(int i = 0; i < allFestivals.size(); i+=1) { %>
        <tr>      
            <td><%=allFestivals.get(i).getFestivalName()%></td>
        </tr>
    <% } %>

Better way is to use c:foreach see link jstl for each

This way you can execute an action when all images inside body or any other container (that depends of your selection) are loaded. PURE JQUERY, no pluggins needed.

var counter = 0;
var size = $('img').length;

$("img").load(function() { // many or just one image(w) inside body or any other container
    counter += 1;
    counter === size && $('body').css('background-color', '#fffaaa'); // any action
}).each(function() {
  this.complete && $(this).load();        
});

This will work for any resolution,

button{
    position:absolute;
    bottom: 5%;
    right:20%;
}

Here's what i used to get the text files with text. I used commons' IOUtils and guava's Resources.

public static String getString(String path) throws IOException {
    try (InputStream stream = Resources.getResource(path).openStream()) {
        return IOUtils.toString(stream);
    }
}

The clone is a shallow copy of the array.

This test code prints:

[1, 2] / [1, 2]
[100, 200] / [100, 2]

because the MutableInteger is shared in both arrays as objects[0] and objects2[0], but you can change the reference objects[1] independently from objects2[1].

Not sure its faster with VBA - the fastest way to do it in the normal Excel programm would be:

1. Ctrl-G
2. A1:X50 Enter
3. Delete

Unless you have to do this very often, entering and then triggering the VBAcode is more effort.

And in case you only want to delete formulas or values, you can insert Ctrl-G, Alt-S to select Goto Special and here select Formulas or Values.

Ups! I was thinking in delphi, there must be something similar in all languages.

Yes, it should be overridden. If you think you need to override equals(), then you need to override hashCode() and vice versa. The general contract of hashCode() is:

1. Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.

2. If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.

3. It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables.

Update: the official type-definitions for React have been including event types as generic types for some time now, so you now have full compile-time checking, and this answer is obsolete.

Is it possible to retrieve the value in a type-safe manner without casting to any?

Yes. If you are certain about the element your handler is attached to, you can do:

<select onChange={ e => this.selectChangeHandler(e) }>
    ...
</select>

private selectChangeHandler(e: React.FormEvent)
{
    var target = e.target as HTMLSelectElement;
    var intval: number = target.value; // Error: 'string' not assignable to 'number'
}

Live demo

The TypeScript compiler will allow this type-assertion, because an HTMLSelectElement is an EventTarget. After that, it should be type-safe, because you know that e.target is an HTMLSelectElement, because you just attached your event handler to it.

However, to guarantee type-safety (which, in this case, is relevant when refactoring), it is also needed to check the actual runtime-type:

if (!(target instanceof HTMLSelectElement))
{
    throw new TypeError("Expected a HTMLSelectElement.");
}

See Apple's guide to Using Swift with Cocoa and Objective-C. This guide covers how to use Objective-C and C code from Swift and vice versa and has recommendations for how to convert a project or mix and match Objective-C/C and Swift parts in an existing project.

The compiler automatically generates Swift syntax for calling C functions and Objective-C methods. As seen in the documentation, this Objective-C:

UITableView *myTableView = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStyleGrouped];

turns into this Swift code:

let myTableView: UITableView = UITableView(frame: CGRectZero, style: .Grouped)

Xcode also does this translation on the fly — you can use Open Quickly while editing a Swift file and type an Objective-C class name, and it'll take you to a Swift-ified version of the class header. (You can also get this by cmd-clicking on an API symbol in a Swift file.) And all the API reference documentation in the iOS 8 and OS X v10.10 (Yosemite) developer libraries is visible in both Objective-C and Swift forms (e.g. UIView).

You cannot directly save a Python file as an exe and expect it to work -- the computer cannot automatically understand whatever code you happened to type in a text file. Instead, you need to use another program to transform your Python code into an exe.

I recommend using a program like Pyinstaller. It essentially takes the Python interpreter and bundles it with your script to turn it into a standalone exe that can be run on arbitrary computers that don't have Python installed (typically Windows computers, since Linux tends to come pre-installed with Python).

To install it, you can either download it from the linked website or use the command:

pip install pyinstaller

...from the command line. Then, for the most part, you simply navigate to the folder containing your source code via the command line and run:

pyinstaller myscript.py

You can find more information about how to use Pyinstaller and customize the build process via the documentation.

You don't necessarily have to use Pyinstaller, though. Here's a comparison of different programs that can be used to turn your Python code into an executable.

Running queries on hot-standby server is somewhat tricky — it can fail, because during querying some needed rows might be updated or deleted on primary. As a primary does not know that a query is started on secondary it thinks it can clean up (vacuum) old versions of its rows. Then secondary has to replay this cleanup, and has to forcibly cancel all queries which can use these rows.

Longer queries will be canceled more often.

You can work around this by starting a repeatable read transaction on primary which does a dummy query and then sits idle while a real query is run on secondary. Its presence will prevent vacuuming of old row versions on primary.

More on this subject and other workarounds are explained in Hot Standby — Handling Query Conflicts section in documentation.

android:drawablePadding is the easiest way to give padding to drawable icon but You can not give specific one side padding like paddingRight or paddingLeft of drawable icon.To achieve that you have to dig into it. And If you apply paddingLeft or paddingRight to EditText then it will place padding to entire EditText along with drawable icon.

<TextView android:layout_width="match_parent"
    android:padding="5dp"
    android:id="@+id/date"
    android:gravity="center|start"
    android:drawableEnd="@drawable/ic_calendar"
    android:background="@drawable/edit_background"
    android:hint="Not Selected"
    android:drawablePadding="10dp"
    android:paddingStart="10dp"
    android:paddingEnd="10dp"
    android:textColor="@color/black"
    android:layout_height="wrap_content"/>

For beginners like me that will stumble upon this tiny problem, in a simple line, with sample conversion to int:

int totalDays = Convert.ToInt32((DateTime.UtcNow.Date - myDateTime.Date).TotalDays);

This calculates the total days from today (DateTime.UtcNow.Date) to a desired date (myDateTime.Date).

If myDateTime is yesterday, or older date than today, this will give a positive (+) integer result.

On the other side, if the myDateTime is tomorrow or on the future date, this will give a negative (-) integer result due to rules of addition.

Happy coding! ^_^

Set the foreign key as a primary key, and then set the relationship on both primary key fields. That's it! You should see a key sign on both ends of the relationship line. This represents a one to one.

Check this : SQL Server Database Design with a One To One Relationship

it has been a while but my answer may help someone:

if you already defined the relation properly you can use this:

        var res = query.Products.Select(m => new
        {
            productID = product.Id,
            categoryID = m.ProductCategory.Select(s => s.Category.ID).ToList(),
        }).ToList();

2019 Update:

Summary - Java NIO (or NIO.2 for async) is still the most comprehensive file processing solution supported in Scala. The following code creates and writes some text to a new file:

import java.io.{BufferedOutputStream, OutputStream}
import java.nio.file.{Files, Paths}

val testFile1 = Paths.get("yourNewFile.txt")
val s1 = "text to insert in file".getBytes()

val out1: OutputStream = new BufferedOutputStream(
  Files.newOutputStream(testFile1))

try {
  out1.write(s1, 0, s1.length)
} catch {
  case _ => println("Exception thrown during file writing")
} finally {
  out1.close()
}

1. Import Java libraries: IO and NIO
2. Create a Path object with your chosen file name
3. Convert your text that you want to insert into a file into a byte array
4. Get your file as a stream: OutputStream
5. Pass your byte array into your output stream's write function
6. Close the stream

You cannot as there is no file input/output in Javascript. See here for a similar question posted.

StrSubstitutor from Apache Commons Lang may be used for string formatting with named placeholders:

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-text</artifactId>
    <version>1.1</version>
</dependency>

https://commons.apache.org/proper/commons-lang/javadocs/api-3.4/org/apache/commons/lang3/text/StrSubstitutor.html :

Substitutes variables within a string by values.

This class takes a piece of text and substitutes all the variables within it. The default definition of a variable is ${variableName}. The prefix and suffix can be changed via constructors and set methods.

Variable values are typically resolved from a map, but could also be resolved from system properties, or by supplying a custom variable resolver.

Example:

String template = "Hi ${name}! Your number is ${number}";

Map<String, String> data = new HashMap<String, String>();
data.put("name", "John");
data.put("number", "1");

String formattedString = StrSubstitutor.replace(template, data);

This is my independent take on this question that I use for my own work. It works in SQL2000 and greater, allows wildcards, column filtering, and will search most of the normal data types.

A pseudo-code description could be select * from * where any like 'foo'

--------------------------------------------------------------------------------
-- Search all columns in all tables in a database for a string.
-- Does not search: image, sql_variant or user-defined types.
-- Exact search always for money and smallmoney; no wildcards for matching these.
--------------------------------------------------------------------------------
declare @SearchTerm nvarchar(4000) -- Can be max for SQL2005+
declare @ColumnName sysname

--------------------------------------------------------------------------------
-- SET THESE!
--------------------------------------------------------------------------------
set @SearchTerm = N'foo' -- Term to be searched for, wildcards okay
set @ColumnName = N'' -- Use to restrict the search to certain columns, wildcards okay, null or empty string for all cols
--------------------------------------------------------------------------------
-- END SET
--------------------------------------------------------------------------------

I don't put it in proc form since I don't want to maintain it across hundreds of DBs and it's really for ad-hoc work anyway. Please feel free to comment on bug-fixes.

Yes using Option Explicit is a good habit. Using .Select however is not :) it reduces the speed of the code. Also fully justify sheet names else the code will always run for the Activesheet which might not be what you actually wanted.

Is this what you are trying?

Option Explicit

Sub Sample()
    Dim lastRow As Long, i As Long
    Dim CopyRange As Range

    '~~> Change Sheet1 to relevant sheet name
    With Sheets("Sheet1")
        lastRow = .Range("A" & .Rows.Count).End(xlUp).Row

        For i = 2 To lastRow
            If Len(Trim(.Range("A" & i).Value)) <> 0 Then
                If CopyRange Is Nothing Then
                    Set CopyRange = .Rows(i)
                Else
                    Set CopyRange = Union(CopyRange, .Rows(i))
                End If
            Else
                Exit For
            End If
        Next

        If Not CopyRange Is Nothing Then
            '~~> Change Sheet2 to relevant sheet name
            CopyRange.Copy Sheets("Sheet2").Rows(1)
        End If
    End With
End Sub

NOTE

If if you have data from Row 2 till Row 10 and row 11 is blank and then you have data again from Row 12 then the above code will only copy data from Row 2 till Row 10

If you want to copy all rows which have data then use this code.

Option Explicit

Sub Sample()
    Dim lastRow As Long, i As Long
    Dim CopyRange As Range

    '~~> Change Sheet1 to relevant sheet name
    With Sheets("Sheet1")
        lastRow = .Range("A" & .Rows.Count).End(xlUp).Row

        For i = 2 To lastRow
            If Len(Trim(.Range("A" & i).Value)) <> 0 Then
                If CopyRange Is Nothing Then
                    Set CopyRange = .Rows(i)
                Else
                    Set CopyRange = Union(CopyRange, .Rows(i))
                End If
            End If
        Next

        If Not CopyRange Is Nothing Then
            '~~> Change Sheet2 to relevant sheet name
            CopyRange.Copy Sheets("Sheet2").Rows(1)
        End If
    End With
End Sub

Hope this is what you wanted?

We can select required fields over values.

Employee.objects.all().values('eng_name','rank')

Regarding Wolfwyrd's anwer: "On Error Resume Next" in fact turns error handling off! Not on. On Error Goto 0 turns error-handling back ON because at the least, we want the machine to catch it if we didn't write it in ourselves. Off = leaving it to you to handle it.

If you use On Error Resume Next, you need to be careful about how much code you include after it: remember, the phrase "If Err.Number <> 0 Then" only refers to the most previous error triggered.

If your block of code after "On Error Resume Next" has several places where you might reasonably expect it to fail, then you must place "If Err.number <> 0" after each and every one of those possible failure lines, to check execution.

Otherwise, after "on error resume next" means just what it says - your code can fail on as many lines as it likes and execution will continue merrily along. That's why it's a pain in the ass.

Have you noticed that you don't get the error if you run

python ./script.py

instead of

python script.py

This is because sys.argv[0] will read ./script.py in the former case, which gives os.path.dirname something to work with. When you don't specify a path, sys.argv[0] reads simply script.py, and os.path.dirname cannot determine a path.

Or you can just run power-shell command to append extra folder to the existing path:

$env:Path += ";C:\temp\terraform" 

If you can't rename the original file, you could also use a symlink:

ln -s foo-bar.py foo_bar.py

Then you can just:

from foo_bar import *

EDIT: Since git 2.13, there is a command to save a specific path to the stash: git stash push <path>. For example:

git stash push -m welcome_cart app/views/cart/welcome.thtml

OLD ANSWER:

You can do that using git stash --patch (or git stash -p) -- you'll enter interactive mode where you'll be presented with each hunk that was changed. Use n to skip the files that you don't want to stash, y when you encounter the one that you want to stash, and q to quit and leave the remaining hunks unstashed. a will stash the shown hunk and the rest of the hunks in that file.

Not the most user-friendly approach, but it gets the work done if you really need it.

I struggled with this issue for a long time and found out that when you run configure, just pass it the path to the correct php-config tool.

In my case, it was

./configure --with-php-config=/usr/local/zend/bin/php-config 

... If you're unsure, run a locate php-config on your machine and find the right one amongst the different versions installed.

Hope this helps somebody in the future.

PS. My default php-config was set to 20090926 which is PHP 5.3. The one I manually entered as a param for ./configure was for PHP 5.4 (2010...)

The NotificationCompat.Builder is the most easy way to create Notifications on all Android versions. You can even use features that are available with Android 4.1. If your app runs on devices with Android >=4.1 the new features will be used, if run on Android <4.1 the notification will be an simple old notification.

To create a simple Notification just do (see Android API Guide on Notifications):

NotificationCompat.Builder mBuilder =
    new NotificationCompat.Builder(this)
    .setSmallIcon(R.drawable.notification_icon)
    .setContentTitle("My notification")
    .setContentText("Hello World!")
    .setContentIntent(pendingIntent); //Required on Gingerbread and below

You have to set at least smallIcon, contentTitle and contentText. If you miss one the Notification will not show.

Beware: On Gingerbread and below you have to set the content intent, otherwise a IllegalArgumentException will be thrown.

To create an intent that does nothing, use:

final Intent emptyIntent = new Intent();
PendingIntent pendingIntent = PendingIntent.getActivity(ctx, NOT_USED, emptyIntent, PendingIntent.FLAG_UPDATE_CURRENT);

You can add sound through the builder, i.e. a sound from the RingtoneManager:

mBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))

The Notification is added to the bar through the NotificationManager:

NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(mId, mBuilder.build());

Use this overload of select:

Obj[] myArray = objects.Select(new Func<Obj,Obj>( o =>
{
    var someLocalVar = o.someVar;

    return new Obj() 
    { 
       Var1 = someLocalVar,
       Var2 = o.var2 
    };
})).ToArray();

First, you are strongly discouraged to do almost any cast, so you should limit it as much as possible! You lose the benefits of Java's compile-time strongly-typed features.

In any case, Class.cast() should be used mainly when you retrieve the Class token via reflection. It's more idiomatic to write

MyObject myObject = (MyObject) object

rather than

MyObject myObject = MyObject.class.cast(object)

EDIT: Errors at compile time

Over all, Java performs cast checks at run time only. However, the compiler can issue an error if it can prove that such casts can never succeed (e.g. cast a class to another class that's not a supertype and cast a final class type to class/interface that's not in its type hierarchy). Here since Foo and Bar are classes that aren't in each other hierarchy, the cast can never succeed.

• You can use WebClient.

• Or (if you need more fine-grained control over the request) HttpWebRequest

• Or, HttpClient in System.Net.Http.dll.

Here's a "translation" to HttpWebRequest (needed rather than WebClient in order to set the referrer). (Uses System.Net and System.IO):

    HttpWebRequest http = (HttpWebRequest)HttpWebRequest.Create(requestUrl))
    http.Referer = referrer;
    HttpWebResponse response = (HttpWebResponse )http.GetResponse();
    using (StreamReader sr = new StreamReader(response.GetResponseStream()))
    {
        string responseJson = sr.ReadToEnd();
        // more stuff
    }

First step is to load your xml string into an XmlDocument, using powershell's unique ability to cast strings to [xml]

$doc = [xml]@'
<xml>
    <Section name="BackendStatus">
        <BEName BE="crust" Status="1" />
        <BEName BE="pizza" Status="1" />
        <BEName BE="pie" Status="1" />
        <BEName BE="bread" Status="1" />
        <BEName BE="Kulcha" Status="1" />
        <BEName BE="kulfi" Status="1" />
        <BEName BE="cheese" Status="1" />
    </Section>
</xml>
'@

Powershell makes it really easy to parse xml with the dot notation. This statement will produce a sequence of XmlElements for your BEName elements:

$doc.xml.Section.BEName

Then you can pipe these objects into the where-object cmdlet to filter down the results. You can use ? as a shortcut for where

$doc.xml.Section.BEName | ? { $_.Status -eq 1 }

The expression inside the braces will be evaluated for each XmlElement in the pipeline, and only those that have a Status of 1 will be returned. The $_ operator refers to the current object in the pipeline (an XmlElement).

If you need to do something for every object in your pipeline, you can pipe the objects into the foreach-object cmdlet, which executes a block for every object in the pipeline. % is a shortcut for foreach:

$doc.xml.Section.BEName | ? { $_.Status -eq 1 } | % { $_.BE + " is delicious" }

Powershell is great at this stuff. It's really easy to assemble pipelines of objects, filter pipelines, and do operations on each object in the pipeline.

Use DecimalFormat.

DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers. It has a variety of features designed to make it possible to parse and format numbers in any locale, including support for Western, Arabic, and Indic digits. It also supports different kinds of numbers, including integers (123), fixed-point numbers (123.4), scientific notation (1.23E4), percentages (12%), and currency amounts ($123). All of these can be localized.

Code snippet -

double i2=i/60000;
tv.setText(new DecimalFormat("##.##").format(i2));

Output -

5.81

getElementById is defined by DOM Level 1 HTML to return null in the case no element is matched.

!==null is the most explicit form of the check, and probably the best, but there is no non-null falsy value that getElementById can return - you can only get null or an always-truthy Element object. So there's no practical difference here between !==null, !=null or the looser if (document.getElementById('xx')).

FYI...if you use TortoiseSVN and you want to create a simple batch file to xcopy (or directory mirror) entire repositories into a "safe" location on a periodic basis, then this is the specific code that you might want to use. It copies over the hidden directories/files, maintains read-only attributes, and all subdirectories and best of all, doesn't prompt for input. Just make sure that you assign folder1 (safe repo) and folder2 (usable repo) correctly.

@echo off
echo "Setting variables..."
set folder1="Z:\Path\To\Backup\Repo\Directory"
set folder2="\\Path\To\Usable\Repo\Directory"
echo "Removing sandbox version..."
IF EXIST %folder1% (
    rmdir %folder1% /s /q
)
echo "Copying official repository into backup location..."
xcopy /e /i /v /h /k %folder2% %folder1%

And, that's it folks!

Add to your scheduled tasks and never look back.

Using Excel 2010 x64. XY plot: I could not see no tabs (it is late and I am probably tired blind, 250 limit?). Here is what worked for me:

Swap the data columns, to end with X_data in column A and Y_data in column B.

My original data had Y_data in column A and X_data in column B, and the graph was rotated 90deg clockwise. I was suffering. Then it hit me: an Excel XY plot literally wants {x,y} pairs, i.e. X_data in first column and Y_data in second column. But it does not tell you this right away. For me an XY plot means Y=f(X) plotted.

Do the following steps

Step 1:

Goto file => /.ssh/config

Save the below lines into the file

Host bitbucket.org
    HostName bitbucket.org
    User git
    IdentityFile /home/apple/myssh-privatekey
    AddKeysToAgent yes

Don't forget to add this line AddKeysToAgent yes

Step 2:

Open the terminal and add the keyset to the ssh-add

$ ssh-add -k /home/apple/myssh-privatekey

provide the passphrase.

Although it does not answer the question directly, one way to scale images is relative to the size (especially width) of the viewport, which is mostly the use case for responsive design. No wrapper elements needed.

img {
    width: 50vw;
}

<img src="" />

If you add height in .wrapper class then your scroll is working, without height scroll is not working.

Try this http://jsfiddle.net/ZcrFr/3/

CSS:

.wrapper {
  position: relative;
  overflow: scroll;
  width: 1000px;
  height: 800px;
}

Here's an alternative approach that writes the std-out and std-err of some command a temporary file, and then checks to see if that file is empty. A benefit of this approach is that it captures both outputs, and does not use sub-shells or pipes. These latter aspects are important because they can interfere with trapping bash exit handling (e.g. here)

tmpfile=$(mktemp)
some-command  &> "$tmpfile"
if [[ $? != 0 ]]; then
    echo "Command failed"
elif [[ -s "$tmpfile" ]]; then
    echo "Command generated output"
else
    echo "Command has no output"
fi
rm -f "$tmpfile"

Follow the steps:

1. Create a context menu like:

2. User needs to right click on the row to get this menu. We need to handle the _MouseClick event and _CellMouseDown event.

selectedBiodataid is the variable that contains the selected row information.

Here is the code:

private void dgrdResults_MouseClick(object sender, MouseEventArgs e)
{   
    if (e.Button == System.Windows.Forms.MouseButtons.Right)
    {                      
        contextMenuStrip1.Show(Cursor.Position.X, Cursor.Position.Y);
    }   
}

private void dgrdResults_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
    //handle the row selection on right click
    if (e.Button == MouseButtons.Right)
    {
        try
        {
            dgrdResults.CurrentCell = dgrdResults.Rows[e.RowIndex].Cells[e.ColumnIndex];
            // Can leave these here - doesn't hurt
            dgrdResults.Rows[e.RowIndex].Selected = true;
            dgrdResults.Focus();

            selectedBiodataId = Convert.ToInt32(dgrdResults.Rows[e.RowIndex].Cells[1].Value);
        }
        catch (Exception)
        {

        }
    }
}

and the output would be:

Here's a great scripted solution for logging people out remotely or locally. I'm using qwinsta to get session information and building an array out of the given output. This makes it really easy to iterate through each entry and log out only the actual users, and not the system or RDP listener itself which usually just throws an access denied error anyway.

$serverName = "Name of server here OR localhost"
$sessions = qwinsta /server $serverName| ?{ $_ -notmatch '^ SESSIONNAME' } | %{
$item = "" | Select "Active", "SessionName", "Username", "Id", "State", "Type", "Device"
$item.Active = $_.Substring(0,1) -match '>'
$item.SessionName = $_.Substring(1,18).Trim()
$item.Username = $_.Substring(19,20).Trim()
$item.Id = $_.Substring(39,9).Trim()
$item.State = $_.Substring(48,8).Trim()
$item.Type = $_.Substring(56,12).Trim()
$item.Device = $_.Substring(68).Trim()
$item
} 

foreach ($session in $sessions){
    if ($session.Username -ne "" -or $session.Username.Length -gt 1){
        logoff /server $serverName $session.Id
    }
}

In the first line of this script give $serverName the appropriate value or localhost if running locally. I use this script to kick users before an automated process attempts to move some folders around. Prevents "file in use" errors for me. Another note, this script will have to be ran as an administrator user otherwise you can get accessed denied trying to log someone out. Hope this helps!

Anonymous classes must extend or implement something, like any other Java class, even if it's just java.lang.Object.

For example:

Runnable r = new Runnable() {
   public void run() { ... }
};

Here, r is an object of an anonymous class which implements Runnable.

An anonymous class can extend another class using the same syntax:

SomeClass x = new SomeClass() {
   ...
};

What you can't do is implement more than one interface. You need a named class to do that. Neither an anonymous inner class, nor a named class, however, can extend more than one class.

You can use any:

print any(df.column == 07311954)
True       #true if it contains the number, false otherwise

If you rather want to see how many times '07311954' occurs in a column you can use:

df.column[df.column == 07311954].count()

I wasn't happy with any of the awk solutions presented here because I wanted to extract the first few columns and then print the rest, so I turned to perl instead. The following code extracts the first two columns, and displays the rest as is:

echo -e "a  b  c  d\te\t\tf g" | \
  perl -ne 'my @f = split /\s+/, $_, 3; printf "first: %s second: %s rest: %s", @f;'

The advantage compared to the perl solution from Chris Koknat is that really only the first n elements are split off from the input string; the rest of the string isn't split at all and therefor stays completely intact. My example demonstrates this with a mix of spaces and tabs.

To change the amount of columns that should be extracted, replace the 3 in the example with n+1.

You should install IIS sub components from

Control Panel -> Programs and Features -> Turn Windows features on or off

Internet Information Services has subsection World Wide Web Services / Application Development Features

There you must check ASP.NET (.NET Extensibility, ISAPI Extensions, ISAPI Filters will be selected automatically). Double check that specific versions are checked. Under Windows Server 2012 R2, these options are split into 4 & 4.5.

Run from cmd:

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir

Finally check in IIS manager, that your application uses application pool with .NET framework version v4.0.

Also, look at this answer.

Setting the objectEquality parameter (third parameter) of the $watch function is definitely the correct way to watch ALL properties of the array.

$scope.$watch('columns', function(newVal) {
    alert('columns changed');
},true); // <- Right here

Piran answers this well enough and mentions $watchCollection as well.

More Detail

The reason I'm answering an already answered question is because I want to point out that wizardwerdna's answer is not a good one and should not be used.

The problem is that the digests do not happen immediately. They have to wait until the current block of code has completed before executing. Thus, watch the length of an array may actually miss some important changes that $watchCollection will catch.

Assume this configuration:

$scope.testArray = [
    {val:1},
    {val:2}
];

$scope.$watch('testArray.length', function(newLength, oldLength) {
    console.log('length changed: ', oldLength, ' -> ', newLength);
});

$scope.$watchCollection('testArray', function(newArray) {
    console.log('testArray changed');
});

At first glance, it may seem like these would fire at the same time, such as in this case:

function pushToArray() {
    $scope.testArray.push({val:3});
}
pushToArray();

// Console output
// length changed: 2 -> 3
// testArray changed

That works well enough, but consider this:

function spliceArray() {
    // Starting at index 1, remove 1 item, then push {val: 3}.
    $testArray.splice(1, 1, {val: 3});
}
spliceArray();

// Console output
// testArray changed

Notice that the resulting length was the same even though the array has a new element and lost an element, so as watch as the $watch is concerned, length hasn't changed. $watchCollection picked up on it, though.

function pushPopArray() {
    $testArray.push({val: 3});
    $testArray.pop();
}
pushPopArray();

// Console output
// testArray change

The same result happens with a push and pop in the same block.

Conclusion

To watch every property in the array, use a $watch on the array iteself with the third parameter (objectEquality) included and set to true. Yes, this is expensive but sometimes necessary.

To watch when object enter/exit the array, use a $watchCollection.

Do NOT use a $watch on the length property of the array. There is almost no good reason I can think of to do so.

This works fine for me

       Excel.Application oXL = null;
        Excel._Workbook oWB = null;
        Excel._Worksheet oSheet = null;

        try
        {
            oXL = new Excel.Application();
            string path = @"C:\Templates\NCRepTemplate.xlt";
            oWB = oXL.Workbooks.Open(path, 0, false, 5, "", "",
                false, Excel.XlPlatform.xlWindows, "", true, false,
                0, true, false, false);

            oSheet = (Excel._Worksheet)oWB.ActiveSheet;
            oSheet.Cells[2, 2] = "Text";

There is already many of answer, but I m still contributing mine one:

public static IPAddress LocalIpAddress() {
    Func<IPAddress, bool> localIpPredicate = ip =>
        ip.AddressFamily == AddressFamily.InterNetwork &&
        ip.ToString().StartsWith("192.168"); //check only for 16-bit block
    return Dns.GetHostEntry(Dns.GetHostName()).AddressList.LastOrDefault(localIpPredicate);
}

One liner:

public static IPAddress LocalIpAddress() => Dns.GetHostEntry(Dns.GetHostName()).AddressList.LastOrDefault(ip => ip.AddressFamily == AddressFamily.InterNetwork && ip.ToString().StartsWith("192.168"));

note: Search from last because it still worked after some interfaces added into device, such as MobileHotspot,VPN or other fancy virtual adapters.

It's the other way around: B.class.isInstance(view)

info frame to show the stack frame info

To read the memory at given addresses you should take a look at x

x/x $esp for hex x/d $esp for signed x/u $esp for unsigned etc. x uses the format syntax, you could also take a look at the current instruction via x/i $eip etc.

Maybe this will help you

You can now use fetch API/ It returns redirected: *boolean*

ToString() gives the most obvious result from a readability perspective, while using Enum.GetName() requires a bit more mental parsing to quickly understand what its trying to do (unless you see the pattern all the time).

From a pure performance point of view, as already provided in @nawfal's answer, Enum.GetName() is better.

If performance is really your goal though, it would be even better to provide a look-up beforehand (using a Dictionary or some other mapping).

In C++/CLI, this would look like

Dictionary<String^, MyEnum> mapping;
for each (MyEnum field in Enum::GetValues(MyEnum::typeid))
{
    mapping.Add(Enum::GetName(MyEnum::typeid), field);
}

Comparison using an enum of 100 items and 1000000 iterations:

Enum.GetName: ~800ms
.ToString(): ~1600ms
Dictionary mapping: ~250ms

I am not sure whether anyone faced issues with getting the whole string "test from adb". Using the escape character in front of the space worked for me.

I was trying to use the React-Native Expo app with create-react-native-app but for some reason it would launch my simulator and just hang without loading the app. The above answer by ipinak above reset the Xcode CLI tools because attempting to update to most recent Xcode CLI was not working. the two commands are:

rm -rf /Library/Developer/CommandLineTools
xcode-select --install

This process take time because of the download. I am leaving this here for any other would be searches for this specific React-Native Expo fix.

Beware that file_get_contents solution doesn't close the connection as it should when a server returns Connection: close in the HTTP header.

CURL solution, on the other hand, terminates the connection so the PHP script is not blocked by waiting for a response.

If you are using WebApi, HttpResponseMessage is a more elegant way to do it

public HttpResponseMessage Get()
{
    return Request.CreateResponse(HttpStatusCode.OK, ListOfMyObject);
}

I like the approach of using a table with a column for each global variable. This way you get autocomplete to aid in coding the retrieval of the variable. The table can be restricted to a single row as outlined here: SQL Server: how to constrain a table to contain a single row?

I thought that I might add this snippet to this old post. This is what I had done in the past, before the icons were fonts:

<i class="social-icon linkedin small" style="border-radius:7.5px;height:15px;width:15px;background-color:white;></i>
<i class="social-icon facebook small" style="border-radius:7.5px;height:15px;width:15px;background-color:white;></i>

This is very similar to @frbl 's sneaky answer, yet it does not use another image. Instead, this sets the background-color of the <i> element to white and uses the CSS property border-radius to make the entire <i> element "rounded." If you noticed, the value of the border-radius (7.5px) is exactly half that of the width and height property (both 15px, making the icon square), making the <i> element circular.

A solve this adding in the option defaultURL the path my application

<forms loginUrl="/Users/Login" protection="All" timeout="2880" name="001WVCookie" path="/" requireSSL="false" slidingExpiration="true" defaultUrl="/Home/Index" cookieless="UseCookies" enableCrossAppRedirects="false" />

Doing it this way has always worked for me, I hope this helps.

var ddl = $("#dropListBuilding");   
for (k = 0; k < buildings.length; k++)
   ddl.append("<option value='" + buildings[k]+ "'>" + buildings[k] + "</option>");

According to the documentation:

Field.choices

An iterable (e.g., a list or tuple) consisting itself of iterables of exactly two items (e.g. [(A, B), (A, B) ...]) to use as choices for this field. If this is given, the default form widget will be a select box with these choices instead of the standard text field.

The first element in each tuple is the actual value to be stored, and the second element is the human-readable name.

So, your code is correct, except that you should either define variables JANUARY, FEBRUARY etc. or use calendar module to define MONTH_CHOICES:

import calendar
...

class MyModel(models.Model):
    ...

    MONTH_CHOICES = [(str(i), calendar.month_name[i]) for i in range(1,13)]

    month = models.CharField(max_length=9, choices=MONTH_CHOICES, default='1')

This has a more elegant explanation and more than one possible solutions. http://kasunh.wordpress.com/2011/10/11/preserving-remote-iphost-while-proxying/

The post describes how to use one popular and one lesser known Apache modules to preserve host/ip while in a setup involving proxying.

sumr is implemented in terms of foldRight:

 final def sumr(implicit A: Monoid[A]): A = F.foldRight(self, A.zero)(A.append) 

foldRight is not always tail recursive, so you can overflow the stack if the collection is too long. See Why foldRight and reduceRight are NOT tail recursive? for some more discussion of when this is or isn't true.

The following are rough guidelines and educated guesses based on experience. You should timeit or profile your concrete use case to get hard numbers, and those numbers may occasionally disagree with the below.

A list comprehension is usually a tiny bit faster than the precisely equivalent for loop (that actually builds a list), most likely because it doesn't have to look up the list and its append method on every iteration. However, a list comprehension still does a bytecode-level loop:

>>> dis.dis(<the code object for `[x for x in range(10)]`>)
 1           0 BUILD_LIST               0
             3 LOAD_FAST                0 (.0)
       >>    6 FOR_ITER                12 (to 21)
             9 STORE_FAST               1 (x)
            12 LOAD_FAST                1 (x)
            15 LIST_APPEND              2
            18 JUMP_ABSOLUTE            6
       >>   21 RETURN_VALUE

Using a list comprehension in place of a loop that doesn't build a list, nonsensically accumulating a list of meaningless values and then throwing the list away, is often slower because of the overhead of creating and extending the list. List comprehensions aren't magic that is inherently faster than a good old loop.

As for functional list processing functions: While these are written in C and probably outperform equivalent functions written in Python, they are not necessarily the fastest option. Some speed up is expected if the function is written in C too. But most cases using a lambda (or other Python function), the overhead of repeatedly setting up Python stack frames etc. eats up any savings. Simply doing the same work in-line, without function calls (e.g. a list comprehension instead of map or filter) is often slightly faster.

Suppose that in a game that I'm developing I need to draw complex and huge maps using for loops. This question would be definitely relevant, for if a list-comprehension, for example, is indeed faster, it would be a much better option in order to avoid lags (Despite the visual complexity of the code).

Chances are, if code like this isn't already fast enough when written in good non-"optimized" Python, no amount of Python level micro optimization is going to make it fast enough and you should start thinking about dropping to C. While extensive micro optimizations can often speed up Python code considerably, there is a low (in absolute terms) limit to this. Moreover, even before you hit that ceiling, it becomes simply more cost efficient (15% speedup vs. 300% speed up with the same effort) to bite the bullet and write some C.

As of C++20, yes.

As of C++17, you can use string_view:

constexpr std::string_view sv = "hello, world";

A string_view is a string-like object that acts as an immutable, non-owning reference to any sequence of char objects.

here it's a simple:

File file = new File(path);
int size = (int) file.length();
byte[] bytes = new byte[size];
try {
    BufferedInputStream buf = new BufferedInputStream(new FileInputStream(file));
    buf.read(bytes, 0, bytes.length);
    buf.close();
} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Add permission in manifest.xml:

 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

I have dealt with this at talkstats.com in posts 94, 101 & 103 found in the thread: Share Your Code. As others have said Rstudio may be a better way to go. I store these functions in my .Rprofile and actually use them a but to automatically block out lines of code quickly.

Not quite as nice as you were hoping for but may be an approach.

var a = {
    ...(condition ? {b: 1} : '') // if condition is true 'b' will be added.
}

I hope this is the much efficient way to add an entry based on the condition. For more info on how to conditionally add entries inside an object literals.

The definition of the perfmon counters has been broken since the beginning and for some reason appears to be too hard to correct.

A good overview of Windows memory management is available in the video "Mysteries of Memory Management Revealed" on MSDN: It covers more topics than needed to track memory leaks (eg working set management) but gives enough detail in the relevant topics.

To give you a hint of the problem with the perfmon counter descriptions, here is the inside story about private bytes from "Private Bytes Performance Counter -- Beware!" on MSDN:

Q: When is a Private Byte not a Private Byte?

A: When it isn't resident.

The Private Bytes counter reports the commit charge of the process. That is to say, the amount of space that has been allocated in the swap file to hold the contents of the private memory in the event that it is swapped out. Note: I'm avoiding the word "reserved" because of possible confusion with virtual memory in the reserved state which is not committed.

From "Performance Planning" on MSDN:

3.3 Private Bytes

3.3.1 Description

Private memory, is defined as memory allocated for a process which cannot be shared by other processes. This memory is more expensive than shared memory when multiple such processes execute on a machine. Private memory in (traditional) unmanaged dlls usually constitutes of C++ statics and is of the order of 5% of the total working set of the dll.

You could use pandas plot as @Bharath suggest:

import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)

Output:

Updated:

from matplotlib.colors import ListedColormap df.set_index('App')\ .reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\ .T.plot(kind='bar', stacked=True, colormap=ListedColormap(sns.color_palette("GnBu", 10)), figsize=(12,6))

Updated Pandas 0.21.0+ reindex_axis is deprecated, use reindex

from matplotlib.colors import ListedColormap

df.set_index('App')\
  .reindex(df.set_index('App').sum().sort_values().index, axis=1)\
  .T.plot(kind='bar', stacked=True,
          colormap=ListedColormap(sns.color_palette("GnBu", 10)), 
          figsize=(12,6))

Output:

If you're on the New Google Sheets, this is all you need to do, according to the docs:

change your recalculation setting to "On change and every minute" in your spreadsheet at File > Spreadsheet settings.

This will make the entire sheet update itself every minute, on the server side, regardless of whether you have the spreadsheet up in your browser or not.

If you're on the old Google Sheets, you'll want to add a cell with this formula to achieve the same functionality:

=GoogleClock()

EDIT to include old and new Google Sheets and change to =GoogleClock().

for the line you wrote

var g = $('<%=Label1.ClientID%>').val(); // Also I tried .text() and .html()

you missed adding #. it should be like this

var g = $('#<%=Label1.ClientID%>').text();

also I do not prefer using this method

that's because if you are calling a control in master or nested master page or if you are calling a control in page from master. Also controls in Repeater. regardless the MVC. this will cause problems.

you should ALWAYS call the ID of the control directly. like this

$('#ControlID')

this is simple and clear. but do not forget to set

ClientIDMode="Static"

in your controls to remain with same ID name after render. that's because ASP.net will modify the ID name in HTML rendered file in some contexts i.e. the page is for Master page the control name will be ConetentPlaceholderName_controlID

I hope it clears the question Good Luck

This is easy in swift 4.2. just use replacingOccurrences(of: " ", with: "_") for replace

var myStr = "This is my string"
let replaced = myStr.replacingOccurrences(of: " ", with: "_")
print(replaced)

If I want to exit a for-to loop, I just set the index beyond the limit:

    For i = 1 To max
        some code
        if this(i) = 25 Then i = max + 1
        some more code...
    Next`

Poppa.

SessionState

• Can be persisted in memory, which makes it a fast solution. Which means state cannot be shared in the Web Farm/Web Garden.
• Can be persisted in a Database, useful for Web Farms / Web Gardens.
• Is Cleared when the session dies - usually after 20min of inactivity.

ViewState

• Is sent back and forth between the server and client, taking up bandwidth.
• Has no expiration date.
• Is useful in a Web Farm / Web Garden

This is a very broad question, so I am going to give a broad answer.

1. A query gets suspended when it is requesting access to a resource that is currently not available. This can be a logical resource like a locked row or a physical resource like a memory data page. The query starts running again, once the resource becomes available. 
2. High disk IO means that a lot of data pages need to be accessed to fulfill the request.

That is all that I can tell from the above screenshot. However, if I were to speculate, you probably have an IO subsystem that is too slow to keep up with the demand. This could be caused by missing indexes or an actually too slow disk. Keep in mind, that 15000 reads for a single OLTP query is slightly high but not uncommon.

It's hard to tell due to the lack of formatting in the question, but I think I see two issues with the ajax call.

1) the application/x-www-form-urlencoded for contentType should be in quotes

2) There should be a comma separating the contentType and async parameters.

If using function onclick DIV and then want to disable click it again you can use this :

for (var i=0;i<document.getElementsByClassName('ads').length;i++){
    document.getElementsByClassName('ads')[i].onclick = false;
}

Example :
HTML

<div id='mybutton'>Click Me</div>

Javascript

document.getElementById('mybutton').onclick = function () {
    alert('You clicked');
    this.onclick = false;
}

You can generate views and controllers for devise customization.

Use

rails g devise:controllers users -c=registrations

and

rails g devise:views 

It will copy particular controllers and views from gem to your application.

Next, tell the router to use this controller:

devise_for :users, :controllers => {:registrations => "users/registrations"}

One solution is to wrap it in a subquery

SELECT *
FROM
(
    SELECT COUNT(column1),column1 FROM table GROUP BY column1
    UNION ALL
    SELECT COUNT(column2),column2 FROM table GROUP BY column2
    UNION ALL
    SELECT COUNT(column3),column3 FROM table GROUP BY column3
) s

Use List<T>.Insert(0, item) or a LinkedList<T>.AddFirst().

If you want see your buffer size in terminal, you can take a look at:

• /proc/sys/net/ipv4/tcp_rmem (for read)
• /proc/sys/net/ipv4/tcp_wmem (for write)

They contain three numbers, which are minimum, default and maximum memory size values (in byte), respectively.

You can use the YouTube JavaScript player API, which has a feature on its own to set playback quality.

player.setPlaybackQuality(suggestedQuality:String):Void

This function sets the suggested video quality for the current video. The function causes the video to reload at its current position in the new quality. If the playback quality does change, it will only change for the video being played. Calling this function does not guarantee that the playback quality will actually change. However, if the playback quality does change, the onPlaybackQualityChange event will fire, and your code should respond to the event rather than the fact that it called the setPlaybackQuality function. [source]

What type of allocation functions are you using? I recently hit a similar error using the Heap* style allocation functions.

It turned out that I was mistakenly creating the heap with the HEAP_NO_SERIALIZE option. This essentially makes the Heap functions run without thread safety. It's a performance improvement if used properly but shouldn't ever be used if you are using HeapAlloc in a multi-threaded program [1]. I only mention this because your post mentions you have a multi-threaded app. If you are using HEAP_NO_SERIALIZE anywhere, delete that and it will likely fix your problem.

[1] There are certain situations where this is legal, but it requires you to serialize calls to Heap* and is typically not the case for multi-threaded programs.

I like the idea of using a directive for this:

.directive('stopEvent', function () {
    return {
        restrict: 'A',
        link: function (scope, element, attr) {
            element.bind('click', function (e) {
                e.stopPropagation();
            });
        }
    };
 });

Then use the directive like:

<div ng-controller="OverlayCtrl" class="overlay" ng-click="hideOverlay()">
    <img src="http://some_src" ng-click="nextImage()" stop-event/>
</div>

If you wanted, you could make this solution more generic like this answer to a different question: https://stackoverflow.com/a/14547223/347216

Hi curious you can validate your google recaptcha at client side also 100% work for me to verify your google recaptcha just see below code
This code at the html body:

 <div class="g-recaptcha" id="rcaptcha" style="margin-left: 90px;" data-sitekey="my_key"></div>
 <span id="captcha" style="margin-left:100px;color:red" />

This code put at head section on call get_action(this) method form button:

function get_action(form) {

var v = grecaptcha.getResponse();
if(v.length == 0)
{
    document.getElementById('captcha').innerHTML="You can't leave Captcha Code empty";
    return false;
}
 if(v.length != 0)
 {
    document.getElementById('captcha').innerHTML="Captcha completed";
    return true; 
 }
}

Between dates Including end points can be written as

public static boolean isDateInBetweenIncludingEndPoints(final Date min, final Date max, final Date date){
    return !(date.before(min) || date.after(max));
}

Update one table using Inner Join

  UPDATE Table1 SET name=ml.name
FROM table1 t inner JOIN
Table2 ml ON t.ID= ml.ID  

Try this, at the end of the each loop, ids array will contain all the hexcodes.

var ids = [];

    $(document).ready(function($) {
    var $div = $("<div id='hexCodes'></div>").appendTo(document.body), code;
    $(".color_cell").each(function() {
        code = $(this).attr('id');
        ids.push(code);
        $div.append(code + "<br />");
    });



});

On Unix time.clock() measures the amount of CPU time that has been used by the current process, so it's no good for measuring elapsed time from some point in the past. On Windows it will measure wall-clock seconds elapsed since the first call to the function. On either system time.time() will return seconds passed since the epoch.

If you're writing code that's meant only for Windows, either will work (though you'll use the two differently - no subtraction is necessary for time.clock()). If this is going to run on a Unix system or you want code that is guaranteed to be portable, you will want to use time.time().

Code check:

This is offtopic here but the people over at CodeReview are more than happy to help you.

I strongly suggest you to do so, there are several things that need attention in your code. Likewise I suggest that you do start reading tutorials since there is really no good reason not to do so.

Lists:

As you said yourself: you need a list of items. The way it is now you only store a reference to one item. Lucky there is exactly that to hold a group of related objects: a List.

Lists are very straightforward to use but take a look at the related documentation anyway.

A very simple example to keep multiple bikes in a list:

List<Motorbike> bikes = new List<Motorbike>();

bikes.add(new Bike { make = "Honda", color = "brown" });
bikes.add(new Bike { make = "Vroom", color = "red" });

And to iterate over the list you can use the foreach statement:

foreach(var bike in bikes) {
     Console.WriteLine(bike.make);
}

The easiest way in plain Java with no dependencies is the following one-liner:

new String(new char[generation]).replace("\0", "-")

Replace generation with number of repetitions, and the "-" with the string (or char) you want repeated.

All this does is create an empty string containing n number of 0x00 characters, and the built-in String#replace method does the rest.

Here's a sample to copy and paste:

public static String repeat(int count, String with) {
    return new String(new char[count]).replace("\0", with);
}

public static String repeat(int count) {
    return repeat(count, " ");
}

public static void main(String[] args) {
    for (int n = 0; n < 10; n++) {
        System.out.println(repeat(n) + " Hello");
    }

    for (int n = 0; n < 10; n++) {
        System.out.println(repeat(n, ":-) ") + " Hello");
    }
}

The most important thing, that all are missing here is... The launchMode of FirstActivity must be singleTop. If it is singleInstance, the onActivityResult in FragmentA will be called just after calling the startActivityForResult method. So, It will not wait for calling of the finish() method in SecondActivity.

So go through the following steps, It will definitely work as it worked for me too after a long research.

In AndroidManifest.xml file, make launchMode of FirstActivity.Java as singleTop.

<activity
        android:name=".FirstActivity"
        android:label="@string/title_activity_main"
        android:launchMode="singleTop"
        android:theme="@style/AppTheme.NoActionBar" />

In FirstActivity.java, override onActivityResult method. As this will call the onActivityResult of FragmentA.

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
}

In FragmentA.Java, override onActivityResult method

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d("FragmentA.java","onActivityResult called");
}

Call startActivityForResult(intent, HOMEWORK_POST_ACTIVITY); from FragmentA.Java

Call finish(); method in SecondActivity.java

Hope this will work.

Binding = your textual representation of a specific column gets mapped to a physical column in some table, in some database, on some server.

Multipart identifier could be: MyDatabase.dbo.MyTable. If you get any of these identifiers wrong, then you have a multipart identifier that cannot be mapped.

The best way to avoid it is to write the query right the first time, or use a plugin for management studio that provides intellisense and thus help you out by avoiding typos.

For anyone finding this, swipe on carousel appears to be native as of about 5 days ago (20 Oct 2018) as per

Get Date::Manip from CPAN, then:

use Date::Manip;
$string = '18-Sep-2008 20:09'; # or a wide range of other date formats
$unix_time = UnixDate( ParseDate($string), "%s" );

edit:

Date::Manip is big and slow, but very flexible in parsing, and it's pure perl. Use it if you're in a hurry when you're writing code, and you know you won't be in a hurry when you're running it.

e.g. Use it to parse command line options once on start-up, but don't use it parsing large amounts of data on a busy web server.

The datetime module will do all the work for you:

>>> import datetime
>>> a = datetime.datetime.now()
>>> # ...wait a while...
>>> b = datetime.datetime.now()
>>> print(b-a)
0:03:43.984000

If you don't want to display the microseconds, just use (as gnibbler suggested):

>>> a = datetime.datetime.now().replace(microsecond=0)
>>> b = datetime.datetime.now().replace(microsecond=0)
>>> print(b-a)
0:03:43

I wasn't satisfied with other solutions because they either draw several time (using more power than necessary) or have problems with orientation. Here is what I used for a scaled square croppedImage from a UIImage * image.

CGFloat minimumSide = fminf(image.size.width, image.size.height);
CGFloat finalSquareSize = 600.;

//create new drawing context for right size
CGRect rect = CGRectMake(0, 0, finalSquareSize, finalSquareSize);
CGFloat scalingRatio = 640.0/minimumSide;
UIGraphicsBeginImageContext(rect.size);

//draw
[image drawInRect:CGRectMake((minimumSide - photo.size.width)*scalingRatio/2., (minimumSide - photo.size.height)*scalingRatio/2., photo.size.width*scalingRatio, photo.size.height*scalingRatio)];

UIImage *croppedImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

import org.springframework.core.io.ClassPathResource;

File folder = new ClassPathResource("sql").getFile();
File[] listOfFiles = folder.listFiles();

It is worth noting that this will limit your deployment options, ClassPathResource.getFile() only works if the container has exploded (unzipped) your war file.

Just to have a simple and complete example for Python 3, which most people seem to be using now.

class MySuper(object):
    def __init__(self,a):
        self.a = a

class MySub(MySuper):
    def __init__(self,a,b):
        self.b = b
        super().__init__(a)

my_sub = MySub(42,'chickenman')
print(my_sub.a)
print(my_sub.b)

gives

42
chickenman

Why does everyone like to list out source files? A simple find command can take care of that easily.

Here's an example of a dirt simple C++ Makefile. Just drop it in a directory containing .C files and then type make...

appname := myapp

CXX := clang++
CXXFLAGS := -std=c++11

srcfiles := $(shell find . -name "*.C")
objects  := $(patsubst %.C, %.o, $(srcfiles))

all: $(appname)

$(appname): $(objects)
    $(CXX) $(CXXFLAGS) $(LDFLAGS) -o $(appname) $(objects) $(LDLIBS)

depend: .depend

.depend: $(srcfiles)
    rm -f ./.depend
    $(CXX) $(CXXFLAGS) -MM $^>>./.depend;

clean:
    rm -f $(objects)

dist-clean: clean
    rm -f *~ .depend

Solution without hardcoding origin in config

Use the following in your global gitconfig

[remote]
    push = +refs/heads/*
    push = +refs/tags/*

This pushes all branches and all tags

Why should you NOT hardcode origin in config?

If you hardcode:

1. You'll end up with origin as a remote in all repos. So you'll not be able to add origin, but you need to use set-url.
2. If a tool creates a remote with a different name push all config will not apply. Then you'll have to rename the remote, but rename will not work because origin already exists (from point 1) remember :)

Fetching is taken care of already by modern git

As per Jakub Narebski's answer:

With modern git you always fetch all branches (as remote-tracking branches into refs/remotes/origin/* namespace

For Finding All the ChildNodes you can use the below Snippet

List<WebElement> childs = MyCurrentWebElement.findElements(By.xpath("./child::*"));

        for (WebElement e  : childs)
        {
            System.out.println(e.getTagName());
        }

Note that this will give all the Child Nodes at same level -> Like if you have structure like this :

<Html> 
<body> 
 <div> ---suppose this is current WebElement 
   <a>
   <a>
      <img>
          <a>
      <img>
   <a>

It will give me tag names of 3 anchor tags here only . If you want all the child Elements recursively , you can replace the above code with MyCurrentWebElement.findElements(By.xpath(".//*"));

Hope That Helps !!

I would sugest to init the Class from RSC:

import Foundation
import UIKit

// Don't forget the delegate!
class ViewController: UIViewController, UITextFieldDelegate {

required init(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

@IBOutlet var myTextField : UITextField?

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    self.myTextField.delegate = self;
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func textFieldShouldReturn(textField: UITextField!) -> Bool {
    self.view.endEditing(true);
    return false;
}

}

The iterator_facade documentation from Boost.Iterator provides what looks like a nice tutorial on implementing iterators for a linked list. Could you use that as a starting point for building a random-access iterator over your container?

If nothing else, you can take a look at the member functions and typedefs provided by iterator_facade and use it as a starting point for building your own.

The easiest way is to use the create Manager method, which creates and saves the object in a single step.

It's changed now. Replace .Builder() with .newBuilder()

As of okhttp:3.9.0 the code goes as follows:

OkHttpClient okHttpClient = new OkHttpClient()
    .newBuilder()
    .connectTimeout(10,TimeUnit.SECONDS)
    .writeTimeout(10,TimeUnit.SECONDS)
    .readTimeout(30,TimeUnit.SECONDS)
    .build();

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

I was having the same issue when trying to change a background images in a array through javascript (jQuery in this case).

Anyway.

Instead of this:

m.setStyle('background-image','url(/templates/site/images/style5/'+backgs[i]+')')

do this:

eval("m.setStyle('background-image','url(/templates/site/images/style5/'+backgs[i]+')')");

Chrome javascript gets screwed when trying to parse a variable inside an element structured with ' . In my case it stopped just before the image array being inserted. Instead of parsing the image url + image name (inside the array), it was parsing just the image url.

You probably need to search inside the code and see where it happens. FF, IE and all other don't have this problem.

I use

button {text-indent:-9999px;}
* html button{font-size:0;display:block;line-height:0}  /* ie6 */
*+html button{font-size:0;display:block;line-height:0}  /* ie7 */

Another reason is the use of the C pre-processor for locating declarations. Even with header guards, .h still have to be parsed over and over, every time they're included. Some compilers support pre-compiled headers that can help with this, but they are not always used.

A static function, unlike a regular (instance) function, is not associated with an instance of the class.

A static class is a class which can only contain static members, and therefore cannot be instantiated.

For example:

class SomeClass {
    public int InstanceMethod() { return 1; }
    public static int StaticMethod() { return 42; }
}

In order to call InstanceMethod, you need an instance of the class:

SomeClass instance = new SomeClass();
instance.InstanceMethod();   //Fine
instance.StaticMethod();     //Won't compile

SomeClass.InstanceMethod();  //Won't compile
SomeClass.StaticMethod();    //Fine

insertAdjacentHTML + outerHTML

elementBefore.insertAdjacentHTML('afterEnd', elementAfter.outerHTML)

Upsides:

• DRYer: you don't have to store the before node in a variable and use it twice. If you rename the variable, on less occurrence to modify.
• golfs better than the insertBefore (break even if the existing node variable name is 3 chars long)

Downsides:

• lower browser support since newer: https://caniuse.com/#feat=insert-adjacent
• will lose properties of the element such as events because outerHTML converts the element to a string. We need it because insertAdjacentHTML adds content from strings rather than elements.

I faced the same situation, I needed to check that exception is thrown when it should, and only when it should. Ended up using the exception handler to my benefit with the following code:

    try {
        functionThatMightThrowException()
    }catch (Exception e){
        Assert.fail("should not throw exception");
    }
    RestOfAssertions();

The main benefit for me was that it is quite straight forward and to check the other way of the "if and only if" is really easy in this same structure

You have to create a variable of the type of the class, and set it equal to a new instance of the object first.

From RFC 6750, Section 1.2:

Bearer Token

A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).

The Bearer Token or Refresh token is created for you by the Authentication server. When a user authenticates your application (client) the authentication server then goes and generates for your a Bearer Token (refresh token) which you can then use to get an access token.

The Bearer Token is normally some kind of cryptic value created by the authentication server, it isn't random it is created based upon the user giving you access and the client your application getting access.

ping (ICMP protocol) and ssh are two different protocols.

1. It could be that ssh service is not running or not installed

2. firewall restriction (local to server like iptables or even sshd config lock down ) or (external firewall that protects incomming traffic to network hosting 111.111.111.111)

First check is to see if ssh port is up

nc -v -w 1 111.111.111.111 -z 22

if it succeeds then ssh should communicate if not then it will never work until restriction is lifted or ssh is started

Remove the dependency "junit:junit:4.12" from app modules...!!! This solution is for gradle to sync all files.

For future references:

You can copy-paste data from en excel-sheet to an SQL-table by doing so:

1. Select the data in Excel and press Ctrl + C
2. In SQL Server Management Studio right click the table and choose Edit Top 200 Rows
3. Scroll to the bottom and select the entire empty row by clicking on the row header
4. Paste the data by pressing Ctrl + V

Note: Often tables have a first column which is an ID-column with an auto generated/incremented ID. When you paste your data it will start inserting the leftmost selected column in Excel into the leftmost column in SSMS thus inserting data into the ID-column. To avoid that keep an empty column at the leftmost part of your selection in order to skip that column in SSMS. That will result in SSMS inserting the default data which is the auto generated ID. Furthermore you can skip other columns by having empty columns at the same ordinal positions in the Excel sheet selection as those columns to be skipped. That will make SSMS insert the default value (or NULL where no default value is specified).

string a = "   Hello   ";
string trimmed = a.Trim();

trimmed is now "Hello"

I've faced to something like this too. in your routes file , export the function as an object like this :

 module.exports = {
     hbd: handlebar
 }

and in your app file , you can have access to the function by .hbd and there is no ptoblem ....!

I had a similar problem and ended up using parse_url and parse_str, which as long as the URL in the parameter is correctly url encoded (which it definitely should) allows you to access both all the parameters of the actual URL, as well as the parameters of the encoded URL in the query parameter, like so:

$get_url = "http://google.com/?var=234&key=234";
$my_url = "http://localhost/test.php?id=" . urlencode($get_url);

function so_5645412_url_params($url) {
    $url_comps = parse_url($url);
    $query = $url_comps['query'];

    $args = array();
    parse_str($query, $args);

    return $args;
}

$my_url_args = so_5645412_url_params($my_url); // Array ( [id] => http://google.com/?var=234&key=234 )
$get_url_args = so_5645412_url_params($my_url_args['id']); // Array ( [var] => 234, [key] => 234 )

Use os.chdir to change directory . Use glob.glob to generate a list of file names which end it '.bak'. The elements of the list are just strings.

Then you could use os.unlink to remove the files. (PS. os.unlink and os.remove are synonyms for the same function.)

#!/usr/bin/env python
import glob
import os
directory='/path/to/dir'
os.chdir(directory)
files=glob.glob('*.bak')
for filename in files:
    os.unlink(filename)

For .NET Core:

string Token = Request.Headers["Custom"];

Or

var re = Request;
var headers = re.Headers;
string token = string.Empty;
StringValues x = default(StringValues);
if (headers.ContainsKey("Custom"))
{
   var m = headers.TryGetValue("Custom", out x);
}

Modern approach

The modern way, for the entire navigation controller… do this once, when your navigation controller's root view is loaded.

[self.navigationController.navigationBar setTitleTextAttributes:
   @{NSForegroundColorAttributeName:[UIColor yellowColor]}];

However, this doesn't seem have an effect in subsequent views.

Classic approach

The old way, per view controller (these constants are for iOS 6, but if want to do it per view controller on iOS 7 appearance you'll want the same approach but with different constants):

You need to use a UILabel as the titleView of the navigationItem.

The label should:

• Have a clear background color (label.backgroundColor = [UIColor clearColor]).
• Use bold 20pt system font (label.font = [UIFont boldSystemFontOfSize: 20.0f]).
• Have a shadow of black with 50% alpha (label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5]).
• You'll want to set the text alignment to centered as well (label.textAlignment = NSTextAlignmentCenter (UITextAlignmentCenter for older SDKs).

Set the label text color to be whatever custom color you'd like. You do want a color that doesn't cause the text to blend into shadow, which would be difficult to read.

I worked this out through trial and error, but the values I came up with are ultimately too simple for them not to be what Apple picked. :)

If you want to verify this, drop this code into initWithNibName:bundle: in PageThreeViewController.m of Apple's NavBar sample. This will replace the text with a yellow label. This should be indistinguishable from the original produced by Apple's code, except for the color.

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self)
    {
        // this will appear as the title in the navigation bar
        UILabel *label = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
        label.backgroundColor = [UIColor clearColor];
        label.font = [UIFont boldSystemFontOfSize:20.0];
        label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
        label.textAlignment = NSTextAlignmentCenter;
                           // ^-Use UITextAlignmentCenter for older SDKs.
        label.textColor = [UIColor yellowColor]; // change this color
        self.navigationItem.titleView = label;
        label.text = NSLocalizedString(@"PageThreeTitle", @"");
        [label sizeToFit];
    }

    return self;
}

Edit: Also, read Erik B's answer below. My code shows the effect, but his code offers a simpler way to drop this into place on an existing view controller.

If you don't want to save instances of the 2 button in the class code, follow this BETTER way (this is more clear and fast!!) :

public void buttonPress(View v) {
  switch (v.getId()) {
    case R.id.button_one:
        // do something
        break;
    case R.id.button_two:
        // do something else
        break;
    case R.id.button_three:
        // i'm lazy, do nothing
        break;
  }
}

var doc = new jsPDF('L', 'pt', [w, h]);

To fix the dimensions.

In fact there are several things you need to check. 1. check your nginx's running status

ps -ef|grep nginx

ps aux|grep nginx|grep -v grep

Here we need to check who is running nginx. please remember the user and group

2. check folder's access status

   ls -alt

3. compare with the folder's status with nginx's

(1) if folder's access status is not right

sudo chmod 755 /your_folder_path

(2) if folder's user and group are not the same with nginx's running's

sudo chown your_user_name:your_group_name /your_folder_path

and change nginx's running username and group

nginx -h

to find where is nginx configuration file

sudo vi /your_nginx_configuration_file

//in the file change its user and group
user your_user_name your_group_name;

//restart your nginx
sudo nginx -s reload

Because nginx default running's user is nobody and group is nobody. if we haven't notice this user and group, 403 will be introduced.

I prefer storing the selected tab in the hashvalue of the window. This also enables sending links to colleagues, who than see "the same" page. The trick is to change the hash of the location when another tab is selected. If you already use # in your page, possibly the hash tag has to be split. In my app, I use ":" as hash value separator.

<ul class="nav nav-tabs" id="myTab">
  <li class="active"><a href="#home">Home</a></li>
  <li><a href="#profile">Profile</a></li>
  <li><a href="#messages">Messages</a></li>
  <li><a href="#settings">Settings</a></li>
</ul>

<div class="tab-content">
  <div class="tab-pane active" id="home">home</div>
  <div class="tab-pane" id="profile">profile</div>
  <div class="tab-pane" id="messages">messages</div>
  <div class="tab-pane" id="settings">settings</div>
</div>

JavaScript, has to be embedded after the above in a <script>...</script> part.

$('#myTab a').click(function(e) {
  e.preventDefault();
  $(this).tab('show');
});

// store the currently selected tab in the hash value
$("ul.nav-tabs > li > a").on("shown.bs.tab", function(e) {
  var id = $(e.target).attr("href").substr(1);
  window.location.hash = id;
});

// on load of the page: switch to the currently selected tab
var hash = window.location.hash;
$('#myTab a[href="' + hash + '"]').tab('show');

This is a cheat, but you can do this, send the value to sever side as a parameter

<script>
var myVar = "hello"
window.location.href = window.location.href.replace(/[\?#].*|$/, "?param=" + myVar); //Send the variable to the server side
</script>

And from the server side, retrieve the parameter

string myVar = Request.QueryString["param"];
Session["SessionName"] = myVar;

hope this helps
