Use the double-star (aka double-splat?) operator:

func(**{'type':'Event'})

is equivalent to

func(type='Event')

Collections.emptyList is immutable so there is a difference between the two versions so you have to consider users of the returned value.

Returning new ArrayList<Foo> always creates a new instance of the object so it has a very slight extra cost associated with it which may give you a reason to use Collections.emptyList. I like using emptyList just because it's more readable.

Short answer: No.

Long answer:

First, without an href attribute, it will not be a link. If it isn't a link then it wont be keyboard (or breath switch, or various other not pointer based input device) accessible (unless you use HTML 5 features of tabindex which are not universally supported). It is very rare that it is appropriate for a control to not have keyboard access.

Second. You should have an alternative for when the JavaScript does not run (because it was slow to load from the server, an Internet connection was dropped (e.g. mobile signal on a moving train), JS is turned off, etc, etc).

Make use of progressive enhancement by unobtrusive JS.

When you get a value from client make and that a value for example.

var current_text = document.getElementById('user_text').value;
        var http = new XMLHttpRequest();
        http.onreadystatechange = function () {

            if (http.readyState == 4 &&  http.status == 200 ){
                var response = http.responseText;
              document.getElementById('server_response').value = response;
                console.log(response.value);


            }

If using the docker-compose file, Based on docker compose version 2.x We can set like as below, by overriding the default config.

I wrote a simple program that solved the easy ones. It took its input from a file which was just a matrix with spaces and numbers. The datastructure to solve it was just a 9 by 9 matrix of a bit mask. The bit mask would specify which numbers were still possible on a certain position. Filling in the numbers from the file would reduce the numbers in all rows/columns next to each known location. When that is done you keep iterating over the matrix and reducing possible numbers. If each location has only one option left you're done. But there are some sudokus that need more work. For these ones you can just use brute force: try all remaining possible combinations until you find one that works.

Based on my own experiences and internet search, I find these places work:

/etc/paths.d

~/.bash_profile

Note that you should open a new terminal window to see the changes.

I did it this way for asynchronous calls using Retrofit 2.0-beta2:

@Override
public void onResponse(Response<RegistrationResponse> response, 
                       Retrofit retrofit) {
    if (response.isSuccess()) {
        // Do success handling here
    } else {
        try {
            MyError myError = (MyError)retrofit.responseConverter(
                    MyError.class, MyError.class.getAnnotations())
                .convert(response.errorBody());
            // Do error handling here
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Just to address the last part of your question, since that really points out the difference between a list and vector in R:

Why do these two expressions not return the same result?

x = list(1, 2, 3, 4); x2 = list(1:4)

A list can contain any other class as each element. So you can have a list where the first element is a character vector, the second is a data frame, etc. In this case, you have created two different lists. x has four vectors, each of length 1. x2 has 1 vector of length 4:

> length(x[[1]])
[1] 1
> length(x2[[1]])
[1] 4

So these are completely different lists.

R lists are very much like a hash map data structure in that each index value can be associated with any object. Here's a simple example of a list that contains 3 different classes (including a function):

> complicated.list <- list("a"=1:4, "b"=1:3, "c"=matrix(1:4, nrow=2), "d"=search)
> lapply(complicated.list, class)
$a
[1] "integer"
$b
[1] "integer"
$c
[1] "matrix"
$d
[1] "function"

Given that the last element is the search function, I can call it like so:

> complicated.list[["d"]]()
[1] ".GlobalEnv" ...

As a final comment on this: it should be noted that a data.frame is really a list (from the data.frame documentation):

A data frame is a list of variables of the same number of rows with unique row names, given class ‘"data.frame"’

That's why columns in a data.frame can have different data types, while columns in a matrix cannot. As an example, here I try to create a matrix with numbers and characters:

> a <- 1:4
> class(a)
[1] "integer"
> b <- c("a","b","c","d")
> d <- cbind(a, b)
> d
 a   b  
[1,] "1" "a"
[2,] "2" "b"
[3,] "3" "c"
[4,] "4" "d"
> class(d[,1])
[1] "character"

Note how I cannot change the data type in the first column to numeric because the second column has characters:

> d[,1] <- as.numeric(d[,1])
> class(d[,1])
[1] "character"

use optional parameter las=2 .

barplot(mytable,main="Car makes",ylab="Freqency",xlab="make",las=2)

Any chance that you changed the name of your table view from "tableView" to "myTableView" at some point?

I use them sometimes as a syntax hack for Map instantiation:

Map map = new HashMap() {{
   put("key", "value");
}};

vs

Map map = new HashMap();
map.put("key", "value");

It saves some redundancy when doing a lot of put statements. However, I have also run into problems doing this when the outer class needs to be serialized via remoting.

Any applications that require CPU usage such as transcoding, display performance and media rendering, whether it be audio or visual, will certainly require (at this point) and benefit from using 64 bit versus 32 bit due to the CPU's ability to deal with the sheer amount of data being thrown at it. It's not so much a question of address space as it is the way the data is being dealt with. A 64 bit processor, given 64 bit code, is going to perform better, especially with mathematically difficult things like transcoding and VoIP data - in fact, any sort of 'math' applications should benefit by the usage of 64 bit CPUs and operating systems. Prove me wrong.

Given that the function strptime() does not work for Windows and strtotime() can return unexpected results, I recommend using date_parse_from_format():

$date = date_parse_from_format('d-m-Y', '22-09-2008');
$timestamp = mktime(0, 0, 0, $date['month'], $date['day'], $date['year']);

One of valid JDBC url is

jdbcUrl=jdbc:mysql://localhost:3306/wsmg?user=root&password=root

Find the text view from the layout.

val textView : TextView = findViewById(R.id.android_text) as TextView

Setting onClickListener on the textview.

textview.setOnClickListener(object: View.OnClickListener {
    override fun onClick(view: View): Unit {
        // Code here.
        textView.text = getString(R.string.name)
    }
})

Argument parentheses can be omitted from View.setOnClickListener if we pass a single function literal argument. So, the simplified code will be:

textview.setOnClickListener {
    // Code here.
    textView.text = getString(R.string.name)
}

serialize() effectively turns the form values into a valid querystring, as such you can simply append to the string:

$.ajax({
    type : 'POST',
    url : 'url',
    data : $('#form').serialize() + "&par1=1&par2=2&par3=232"
}

Turns out I, like @Grey Black, had to actually install v62.1 of icu4c. Nothing else worked.

However, brew switch icu4c 62.1 only works if you have installed 62.1 in the past. If you haven't there's more legwork involved. Homebrew does not make it easy to install previous versions of formulae.

Here's how I did it:

1. We first need a deep clone of the Homebrew repo. This may take a while: git -C $(brew --repo homebrew/core) fetch --unshallow
2. brew log icu4c to track down a commit that references 62.1; 575eb4b does the trick.
3. cd $(brew --repo homebrew/core)
4. git checkout 575eb4b -- Formula/icu4c.rb
5. brew uninstall --ignore-dependencies icu4c
6. brew install icu4c You should now have the correct version of the dependency! Now just to...
7. git reset && git checkout . Cleanup your modified recipe.
8. brew pin icu4c Pin the dependency to prevent it from being accidentally upgraded in the future

If you decide you do want to upgrade it at some point, make sure to run brew unpin icu4c

Right click on the project and select [replace with] -> Head Revision .Now select pull changes in current branch or pull changes from upstream.

If you want "Socks Proxy", inform the "socksProxyHost" and "socksProxyPort" VM arguments.

e.g.

java -DsocksProxyHost=127.0.0.1 -DsocksProxyPort=8080 org.example.Main

For swift 3 and 4, you can do this. Good practice is set name of Storyboard equal to StoryboardID.

enum StoryBoardName{
   case second = "SecondViewController"
}
extension UIStoryBoard{
   class func load(_ storyboard: StoryBoardName) -> UIViewController{
      return UIStoryboard(name: storyboard.rawValue, bundle: nil).instantiateViewController(withIdentifier: storyboard.rawValue)
   }
}

and then you can load your Storyboard in your ViewController like this:

class MyViewController: UIViewController{
     override func viewDidLoad() {
        super.viewDidLoad()
        guard let vc = UIStoryboard.load(.second) as? SecondViewController else {return}
        self.present(vc, animated: true, completion: nil)
     }

}

When you create a new Storyboard just set the same name on StoryboardID and add Storyboard name in your enum "StoryBoardName"

You could use a VB Script I wrote exactly for this purpose: https://github.com/ezrarieben/mssql-backup-vbs/

Schedule a task in the "Task Scheduler" to execute the script as you like and it'll backup the entire DB to a BAK file and save it wherever you specify.

List.toArray() necessarily returns an array of Object. To get an array of String, you need to use the casting syntax:

String[] strarray = strlist.toArray(new String[0]);

See the javadoc for java.util.List for more.

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

@Adrian's answer is perfectly suitable, I just wanted to share another way of achieving the same result:

select nvl(a.id, b.id)
from a full outer join b on a.id = b.id
order by b.id;

You can also do it this way:

$current_url = 'http://' .$_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

It's a bit faster.

After trying to manually uninstall, and then downloading another copy of the VS 2015 community installer for use with the force uninstall command line argument (Original answer by Michael Schuchardt), I was still unable to modify the install directory.

After testing further, I found that Unity (which integrates with Visual Studio as of Unity 5.2) also had to be removed. At this point Visual Studio Uninstaller (link to latest release on Github) can be used for the final removal of remaining any remaining components.

You will now be able to run the Visual Studio Installer and select a directory or, alternatively, run the install from command line using the "/CustomInstallPath ..." argument.

Some project might want to add *.manifest to their visual studio gitignore.io file.

That is because some Visual Studio project properties of new projects are set to generate a manifest file.

See "Manifest Generation in Visual Studio"

But if you have generated them and they are static (not changing over time), then it is a good idea to remove them from the .gitignore file.

That is what a project like Git for Windows just did (for Git 2.24, Q4 2019)

See commit aac6ff7 (05 Sep 2019) by Johannes Schindelin (dscho).
^{(Merged by Junio C Hamano -- gitster -- in commit 59438be, 30 Sep 2019)}

.gitignore: stop ignoring .manifest files

On Windows, it is possible to embed additional metadata into an executable by linking in a "manifest", i.e. an XML document that describes capabilities and requirements (such as minimum or maximum Windows version).
These XML documents are expected to be stored in .manifest files.

At least some Visual Studio versions auto-generate .manifest files when none is specified explicitly, therefore we used to ask Git to ignore them.

However, we do have a beautiful .manifest file now: compat/win32/git.manifest, so neither does Visual Studio auto-generate a manifest for us, nor do we want Git to ignore the .manifest files anymore.

Below code changes to 'datetime' type and also formats in the given format string. Works well!

df['DOB']=pd.to_datetime(df['DOB'].dt.strftime('%m/%d/%Y'))

When you want to run an executable file from the Command prompt, (cmd.exe), or a batch file, it will:

• Search the current working directory for the executable file.
• Search all locations specified in the %PATH% environment variable for the executable file.

If the file isn't found in either of those options you will need to either:

1. Specify the location of your executable.
2. Change the working directory to that which holds the executable.
3. Add the location to %PATH% by apending it, (recommended only with extreme caution).

You can see which locations are specified in %PATH% from the Command prompt, Echo %Path%.

Because of your reported error we can assume that Mobile.exe is not in the current directory or in a location specified within the %Path% variable, so you need to use 1., 2. or 3..

Examples for 1.

C:\directory_path_without_spaces\My-App\Mobile.exe

or:

"C:\directory path with spaces\My-App\Mobile.exe"

Alternatively you may try:

Start C:\directory_path_without_spaces\My-App\Mobile.exe

or

Start "" "C:\directory path with spaces\My-App\Mobile.exe"

Where "" is an empty title, (you can optionally add a string between those doublequotes).

Examples for 2.

CD /D C:\directory_path_without_spaces\My-App
Mobile.exe

or

CD /D "C:\directory path with spaces\My-App"
Mobile.exe

You could also use the /D option with Start to change the working directory for the executable to be run by the start command

Start /D C:\directory_path_without_spaces\My-App Mobile.exe

or

Start "" /D "C:\directory path with spaces\My-App" Mobile.exe

If you need a multidimensional PHP array to be printed directly into the html page source code, and in an indented human-readable Javascript Object Notation (aka JSON) fashion, use this nice function I found in http://php.net/manual/en/function.json-encode.php#102091 coded by somebody nicknamed "bohwaz".

<?php

function json_readable_encode($in, $indent = 0, $from_array = false)
{
    $_myself = __FUNCTION__;
    $_escape = function ($str)
    {
        return preg_replace("!([\b\t\n\r\f\"\\'])!", "\\\\\\1", $str);
    };

    $out = '';

    foreach ($in as $key=>$value)
    {
        $out .= str_repeat("\t", $indent + 1);
        $out .= "\"".$_escape((string)$key)."\": ";

        if (is_object($value) || is_array($value))
        {
            $out .= "\n";
            $out .= $_myself($value, $indent + 1);
        }
        elseif (is_bool($value))
        {
            $out .= $value ? 'true' : 'false';
        }
        elseif (is_null($value))
        {
            $out .= 'null';
        }
        elseif (is_string($value))
        {
            $out .= "\"" . $_escape($value) ."\"";
        }
        else
        {
            $out .= $value;
        }

        $out .= ",\n";
    }

    if (!empty($out))
    {
        $out = substr($out, 0, -2);
    }

    $out = str_repeat("\t", $indent) . "{\n" . $out;
    $out .= "\n" . str_repeat("\t", $indent) . "}";

    return $out;
}

?>       

Most of the people already gave the answer but this one is just for making someone's life easier.

TL;DR

You must add the test folder as source.

1. Right click on java directory under test
2. Mark it as Tests
3. Add src/test/java in Test Source Folders

Thats it, IntelliJ will consider them as test source.

Just import AVFoundation and use AVMakeRectWithAspectRatioInsideRect(CGRectCurrentSize, CGRectMake(0, 0, YOUR_WIDTH, CGFLOAT_MAX)

You don't need to change the delimiter to display the right part of the string with cut.

The -f switch of the cut command is the n-TH element separated by your delimiter : :, so you can just type :

 grep puddle2_1557936 | cut -d ":" -f2

Another solutions (adapt it a bit) if you want fun :

Using grep :

grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                        
/home/rogers.williams/folderz/puddle2

or still with look around regex

grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                    
/home/rogers.williams/folderz/puddle2

or with perl :

perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                      
/home/rogers.williams/folderz/puddle2

or using ruby (thanks to glenn jackman)

ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with awk :

awk -F'puddle2_1557936:' '{print $2}'  <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with python :

python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or using only bash :

IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2

or using js in a shell :

js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2

or using php in a shell :

php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2' 
/home/rogers.williams/folderz/puddle2

Short answer: Use the change event. Here's a couple of practical examples. Since I misread the question, I'll include jQuery examples along with plain JavaScript. You're not gaining much, if anything, by using jQuery though.

Single checkbox

Using querySelector.

var checkbox = document.querySelector("input[name=checkbox]");

checkbox.addEventListener('change', function() {
  if (this.checked) {
    console.log("Checkbox is checked..");
  } else {
    console.log("Checkbox is not checked..");
  }
});

<input type="checkbox" name="checkbox" />

Single checkbox with jQuery

$('input[name=checkbox]').change(function() {
  if ($(this).is(':checked')) {
    console.log("Checkbox is checked..")
  } else {
    console.log("Checkbox is not checked..")
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input type="checkbox" name="checkbox" />

Multiple checkboxes

Here's an example of a list of checkboxes. To select multiple elements we use querySelectorAll instead of querySelector. Then use Array.filter and Array.map to extract checked values.

// Select all checkboxes with the name 'settings' using querySelectorAll.
var checkboxes = document.querySelectorAll("input[type=checkbox][name=settings]");
let enabledSettings = []

/*
For IE11 support, replace arrow functions with normal functions and
use a polyfill for Array.forEach:
https://vanillajstoolkit.com/polyfills/arrayforeach/
*/

// Use Array.forEach to add an event listener to each checkbox.
checkboxes.forEach(function(checkbox) {
  checkbox.addEventListener('change', function() {
    enabledSettings = 
      Array.from(checkboxes) // Convert checkboxes to an array to use filter and map.
      .filter(i => i.checked) // Use Array.filter to remove unchecked checkboxes.
      .map(i => i.value) // Use Array.map to extract only the checkbox values from the array of objects.
      
    console.log(enabledSettings)
  })
});

<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Multiple checkboxes with jQuery

let checkboxes = $("input[type=checkbox][name=settings]")
let enabledSettings = [];

// Attach a change event handler to the checkboxes.
checkboxes.change(function() {
  enabledSettings = checkboxes
    .filter(":checked") // Filter out unchecked boxes.
    .map(function() { // Extract values using jQuery map.
      return this.value;
    }) 
    .get() // Get array.
    
  console.log(enabledSettings);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

In case the dictionaries are only uniquely identified by all items (ID is not available) you can use the answer using JSON. The following is an alternative that does not use JSON, and will work as long as all dictionary values are immutable

[dict(s) for s in set(frozenset(d.items()) for d in L)]

Android comes with an input command-line tool that can simulate miscellaneous input events. To simulate tapping, it's:

input tap x y

You can use the adb shell ( > 2.3.5) to run the command remotely:

adb shell input tap x y

Or simple try:

> sudo easy_install MySQL-python

If it gives a error like below:

EnvironmentError: mysql_config not found

, then just run this

> export PATH=$PATH:/usr/local/mysql/bin

You can always look at how wide your font is and take the average character pixel size. Then just multiply that by the number of characters you want. It's a bit tacky but it works as a quick fix.

Use below code for sorting in alphabetical order:

    NSArray *unsortedStrings = @[@"Verdana", @"MS San Serif", @"Times New Roman",@"Chalkduster",@"Impact"];

    NSArray *sortedStrings =
    [unsortedStrings sortedArrayUsingSelector:@selector(compare:)];

    NSLog(@"Unsorted Array : %@",unsortedStrings);        
    NSLog(@"Sorted Array : %@",sortedStrings);

Below is console log :

2015-04-02 16:17:50.614 ToDoList[2133:100512] Unsorted Array : (
    Verdana,
    "MS San Serif",
    "Times New Roman",
    Chalkduster,
    Impact
)

2015-04-02 16:17:50.615 ToDoList[2133:100512] Sorted Array : (
    Chalkduster,
    Impact,
    "MS San Serif",
    "Times New Roman",
    Verdana
)

Use Array.prototype.filter() function.

    let emailRegEx = "^(?:(?:(?:(?: )*(?:(?:(?:\\t| )*\\r\\n)?(?:\\t| )+))+(?: )*)|(?: )+)?(?:(?:(?:[-A-Za-z0-9!#$%&’*+/=?^_'{|}~]+(?:\\.[-A-Za-z0-9!#$%&’*+/=?^_'{|}~]+)*)|(?:\"(?:(?:(?:(?: )*(?:(?:[!#-Z^-~]|\\[|\\])|(?:\\\\(?:\\t|[ -~]))))+(?: )*)|(?: )+)\"))(?:@)(?:(?:(?:[A-Za-z0-9](?:[-A-Za-z0-9]{0,61}[A-Za-z0-9])?)(?:\\.[A-Za-z0-9](?:[-A-Za-z0-9]{0,61}[A-Za-z0-9])?)*)|(?:\\[(?:(?:(?:(?:(?:[0-9]|(?:[1-9][0-9])|(?:1[0-9][0-9])|(?:2[0-4][0-9])|(?:25[0-5]))\\.){3}(?:[0-9]|(?:[1-9][0-9])|(?:1[0-9][0-9])|(?:2[0-4][0-9])|(?:25[0-5]))))|(?:(?:(?: )*[!-Z^-~])*(?: )*)|(?:[Vv][0-9A-Fa-f]+\\.[-A-Za-z0-9._~!$&'()*+,;=:]+))\\])))(?:(?:(?:(?: )*(?:(?:(?:\\t| )*\\r\\n)?(?:\\t| )+))+(?: )*)|(?: )+)?$"

constructor(private activatedRoute: ActivatedRoute) {

this.activatedRoute.queryParams.subscribe(params => {

This works for me!

This works for me:

git fetch
git rebase --autostash FETCH_HEAD

Well you are trying to compare Date with Nvarchar which is wrong. Should be

Where dates between date1 And date2
-- both date1 & date2 should be date/datetime

If date1,date2 strings; server will convert them to date type before filtering.

I am assuming you are using Eclipse as your developing environment.

Eclipse Juno, Indigo and Kepler when using the bundled maven version(m2e), are not suppressing the message SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". This behaviour is present from the m2e version 1.1.0.20120530-0009 and onwards.

Although, this is indicated as an error your logs will be saved normally. The highlighted error will still be present until there is a fix of this bug. More about this in the m2e support site.

The current available solution is to use an external maven version rather than the bundled version of Eclipse. You can find about this solution and more details regarding this bug in the question below which i believe describes the same problem you are facing.

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". error

What helped me... changing sendmail parameters from -bs to -t.

'sendmail' => '/your/sendmail/path -t',

This problem is almost always related to the GDI Object count, User Object count or Handle count and usually not because of an out-of-memory condition on your machine.

When I am tracking one of these bugs, I open ProcessExplorer and watch these columns: Handles, Threads, GDI Objects, USER Objects, Private Bytes, Virtual Size and Working Set.

(In my experience, the problem is usually an object leak due to an event handler holding the object and preventing it from being disposed.)

You can manual disable ssl verfiy, and try again. :)

git config --global http.sslverify false

You can't call a PHP function with Javascript, in the same way you can't call arbitrary PHP functions when you load a page (just think of the security implications).

If you need to wrap your code in a function for whatever reason, why don't you either put a function call under the function definition, eg:

function test() {
    // function code
}

test();

Or, use a PHP include:

include 'functions.php'; // functions.php has the test function
test();

C++20 will include std::format which resembles sprintf in terms of API but is fully type-safe, works with user-defined types, and uses Python-like format string syntax. Here's how you will be able to format std::string and write it to a stream:

std::string s = "foo";
std::cout << std::format("Look, a string: {}", s);

Alternatively, you could use the {fmt} library to format a string and write it to stdout or a file stream in one go:

fmt::print("Look, a string: {}", s);

As for sprintf or most of the other answers here, unfortunately they use varargs and are inherently unsafe unless you use something like GCC's format attribute which only works with literal format strings. You can see why these functions are unsafe on the following example:

std::string format_str = "%s";
string_format(format_str, format_str[0]);

where string_format is an implementation from the Erik Aronesty's answer. This code compiles, but it will most likely crash when you try to run it:

$ g++ -Wall -Wextra -pedantic test.cc 
$ ./a.out 
Segmentation fault: 11

Disclaimer: I'm the author of {fmt} and C++20 std::format.

No. It's very easy to check.

public class Catch {
    public static void main(String[] args) {
        try {
            throw new java.io.IOException();
        } catch (java.io.IOException exc) {
            System.err.println("In catch IOException: "+exc.getClass());
            throw new RuntimeException();
        } catch (Exception exc) {
            System.err.println("In catch Exception: "+exc.getClass());
        } finally {
            System.err.println("In finally");
        }
    }
}

Should print:

In catch IOException: class java.io.IOException
In finally
Exception in thread "main" java.lang.RuntimeException
        at Catch.main(Catch.java:8)

Technically that could have been a compiler bug, implementation dependent, unspecified behaviour, or something. However, the JLS is pretty well nailed down and the compilers are good enough for this sort of simple thing (generics corner case may be a different matter).

Also note, if you swap around the two catch blocks, it wont compile. The second catch would be completely unreachable.

Note the finally block always runs even if a catch block is executed (other than silly cases, such as infinite loops, attaching through the tools interface and killing the thread, rewriting bytecode, etc.).

simply use delete, but be aware that you should read fully what the effects are of using this:

 delete object.index; //true
 object.index; //undefined

but if I was to use like so:

var x = 1; //1
delete x; //false
x; //1

but if you do wish to delete variables in the global namespace, you can use it's global object such as window, or using this in the outermost scope i.e

var a = 'b';
delete a; //false
delete window.a; //true
delete this.a; //true

http://perfectionkills.com/understanding-delete/

another fact is that using delete on an array will not remove the index but only set the value to undefined, meaning in certain control structures such as for loops, you will still iterate over that entity, when it comes to array's you should use splice which is a prototype of the array object.

Example Array:

var myCars=new Array();
myCars[0]="Saab";
myCars[1]="Volvo";
myCars[2]="BMW";

if I was to do:

delete myCars[1];

the resulting array would be:

["Saab", undefined, "BMW"]

but using splice like so:

myCars.splice(1,1);

would result in:

["Saab", "BMW"]

The Standard C++11 way (if you don't care about the output format):

#include <string>

auto str = std::to_string(42.5); 

to_string is a new library function introduced in N1803 (r0), N1982 (r1) and N2408 (r2) "Simple Numeric Access". There are also the stod function to perform the reverse operation.

If you do want to have a different output format than "%f", use the snprintf or ostringstream methods as illustrated in other answers.

You can use php magic methods __get and __set.

<?php
class MyClass {
  private $firstField;
  private $secondField;

  public function __get($property) {
    if (property_exists($this, $property)) {
      return $this->$property;
    }
  }

  public function __set($property, $value) {
    if (property_exists($this, $property)) {
      $this->$property = $value;
    }

    return $this;
  }
}
?>

inp0= pd.read_csv("bank_marketing_updated_v1.csv",skiprows=2)

or if you want to do in existing dataframe

simply do following command

All of the answers in this question helped me but I thought I'd add some additional information for posterity.

It turned out that I had a test dependency on gwt-test-utils which brought in the gwt-dev package. Unfortunately gwt-dev contains a full copy of Jetty, JSP, JSTL, etc. which was ahead of the proper packages on the classpath. So even though I had proper dependencies on the JSTL 1.2 it would loading the 1.0 version internal to gwt-dev. Grumble.

The solution for me was to not run with test scope so I don't pick up the gwt-test-utils package at runtime. Removing the gwt-dev package from the classpath in some other manner would also have fixed the problem.

The most famous library to create some GUI in C language is certainly GTK.

With this library you can easily create some buttons (for your example). When a user clicks on the button, a signal is emitted and you can write a handler to do some actions.

.c_str() returns a const char*. If you need a mutable version, you will need to produce a copy yourself.

Material desing buttons add to button xml: style="@style/Widget.MaterialComponents.Button.UnelevatedButton"

As described in the Android documentation, the SDK level (integer) the phone is running is available in:

android.os.Build.VERSION.SDK_INT

The class corresponding to this int is in the android.os.Build.VERSION_CODES class.

Code example:

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
    // Do something for lollipop and above versions
} else{
    // do something for phones running an SDK before lollipop
}

Edit: This SDK_INT is available since Donut (android 1.6 / API4) so make sure your application is not retro-compatible with Cupcake (android 1.5 / API3) when you use it or your application will crash (thanks to Programmer Bruce for the precision).

Corresponding android documentation is here and here

I am adding this answer as an alternative to doing a formal checkout or some similar local operation. Assuming that you have access to the web interface of your Git provider, you might be able to directly view any file at a given desired commit. For example, on GitHub you may use something like:

https://github.com/hubotio/hubot/blob/ed25584f/src/adapter.coffee

Here ed25584f is the first 8 characters from the SHA-1 hash of the commit of interest, followed by the path to the source file.

Similary, on Bitbucket we can try:

https://bitbucket.org/cofarrell/stash-browse-code-plugin/src/06befe08

In this case, we place the commit hash at the end of the source URL.

Building up on Shavy Levy answer:

[bool]($var -as [int])

Because $null is evaluated to false (in bool), this statement Will give you true or false depending if the casting succeeds or not.

The fastest way should be:

<%@ page import="java.util.Map" %>
Map<String, String[]> parameters = request.getParameterMap();
for (Map.Entry<String, String[]> entry : parameters.entrySet()) {
    if (entry.getKey().startsWith("question")) {
        String[] values = entry.getValue();
        // etc.

Note that you can't do:

for (Map.Entry<String, String[]> entry : 
     request.getParameterMap().entrySet()) { // WRONG!

for reasons explained here.

Maybe it can be useful to know that the bitwise AND and bitwise OR operators are always evaluated before conditional AND and conditional OR used in the same expression.

if ( (1>2) && (2>1) | true) // false!

Using Acrobat reader is not a good solution, especially command line attributes are not documented. Additionally Acrobat reader's window stays open after printing process. PDF files are well known by printer drivers, so you may find better tools, like 2Printer.exe or RawFilePrinter.exe. In my opinion RawFilePrinter has better support and clear licencing process (you pay donation once and you can redistribute RawFilePrinter in many project you like - even new versions work with previously purchased license)

RawFilePrinter.exe -p "c:\Users\Me\Desktop\mypdffile.pdf" "Canon Printer" 
IF %ERRORLEVEL% 1(
    echo "Error!"
)

For Set you can use TreeSet. TreeSet orders it's elements on the basis of a natural ordering or any sorting order passed to the Comparable for that particular object. For map use TreeMap. TreeMap provides the sorting over keys. To add an object as a key to the TreeMap that class should implement comparable interface which in turn forces to implement compare to() method which contains the definition of the sorting order. http://techmastertutorial.in/java-collection-impl.html

Iterate through strings characters and use functions of 'Char' called 'IsLetter' and 'IsDigit'.

If you need something more specific - use Regex class.

You can use the start (^) and end ($) of line indicators:

^[0-9]{2}$

Some language also have functions that allows you to match against an entire string, where-as you were using a find function. Matching against the entire string will make your regex work as an alternative to the above. The above regex will also work, but the ^ and $ will be redundant.

You could move the common parts to another configuration file and include from both server contexts. This should work:

server {
  listen 80;
  server_name server1.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

server {
  listen 80;
  server_name another-one.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

Edit: Here's an example that's actually copied from my running server. I configure my basic server settings in /etc/nginx/sites-enabled (normal stuff for nginx on Ubuntu/Debian). For example, my main server bunkus.org's configuration file is /etc/nginx/sites-enabled and it looks like this:

server {
  listen   80 default_server;
  listen   [2a01:4f8:120:3105::101:1]:80 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-80;
}

server {
  listen   443 default_server;
  listen   [2a01:4f8:120:3105::101:1]:443 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/ssl-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-443;
}

As an example here's the /etc/nginx/include.d/all-common file that's included from both server contexts:

index index.html index.htm index.php .dirindex.php;
try_files $uri $uri/ =404;

location ~ /\.ht {
  deny all;
}

location = /favicon.ico {
  log_not_found off;
  access_log off;
}

location ~ /(README|ChangeLog)$ {
  types { }
  default_type text/plain;
}

If you are using Kotlin in android then you can create Extension function.
Extension Functions are defined outside of any class - yet they reference the class name and can use this. In our case we use applicationContext.
So in Utility class you can define all extension functions.

Utility.kt

fun Context.loadJSONFromAssets(fileName: String): String {
    return applicationContext.assets.open(fileName).bufferedReader().use { reader ->
        reader.readText()
    }
}

MainActivity.kt

You can define private function for load JSON data from assert like this:

 lateinit var facilityModelList: ArrayList<FacilityModel>
 private fun bindJSONDataInFacilityList() {
    facilityModelList = ArrayList<FacilityModel>()
    val facilityJsonArray = JSONArray(loadJSONFromAsserts("NDoH_facility_list.json")) // Extension Function call here
    for (i in 0 until facilityJsonArray.length()){
        val facilityModel = FacilityModel()
        val facilityJSONObject = facilityJsonArray.getJSONObject(i)
        facilityModel.Facility = facilityJSONObject.getString("Facility")
        facilityModel.District = facilityJSONObject.getString("District")
        facilityModel.Province = facilityJSONObject.getString("Province")
        facilityModel.Subdistrict = facilityJSONObject.getString("Facility")
        facilityModel.code = facilityJSONObject.getInt("code")
        facilityModel.gps_latitude = facilityJSONObject.getDouble("gps_latitude")
        facilityModel.gps_longitude = facilityJSONObject.getDouble("gps_longitude")

        facilityModelList.add(facilityModel)
    }
}

You have to pass facilityModelList in your ListView

FacilityModel.kt

class FacilityModel: Serializable {
    var District: String = ""
    var Facility: String = ""
    var Province: String = ""
    var Subdistrict: String = ""
    var code: Int = 0
    var gps_latitude: Double= 0.0
    var gps_longitude: Double= 0.0
}

In my case JSON response start with JSONArray

[
  {
    "code": 875933,
    "Province": "Eastern Cape",
    "District": "Amathole DM",
    "Subdistrict": "Amahlathi LM",
    "Facility": "Amabele Clinic",
    "gps_latitude": -32.6634,
    "gps_longitude": 27.5239
  },

  {
    "code": 455242,
    "Province": "Eastern Cape",
    "District": "Amathole DM",
    "Subdistrict": "Amahlathi LM",
    "Facility": "Burnshill Clinic",
    "gps_latitude": -32.7686,
    "gps_longitude": 27.055
  }
]

You can set the following environment variable:

PIP_TARGET=/path/to/pip/dir

2. To read input when you call a method with some arguments/parameters:

Look at the find command.

What you are looking for is something like

find . -name "*.xls" -type f -exec program 

Post edit

find . -name "*.xls" -type f -exec xls2csv '{}' '{}'.csv;

will execute xls2csv file.xls file.xls.csv

Closer to what you want.

Just saw a variation on this issue: I went into the project.pbxproj file as per Brad Smith's notes above, except in this case all of the PROVISIONING_PROFILE lines seemed to be correct, with no occurrence of the "bad" profile string that Xcode couldn't find.

However, the fix was the same: deleting ALL of the PROVISIONING_PROFILE lines in project.pbxproj, even though they looked "good" in theory, and then reopening the project in Xcode.

Try this......

First create an xml file named button_pressed.xml These are it's contents.

<?xml version="1.0" encoding="utf-8"?>
<selector
  xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" 
          android:state_pressed="false" 
          android:drawable="@drawable/icon_1" />
    <item android:state_focused="true" 
          android:state_pressed="true"
          android:drawable="@drawable/icon_1_press" />
    <item android:state_focused="false" 
          android:state_pressed="true"
            android:drawable="@drawable/icon_1_press" />
    <item android:drawable="@drawable/icon_1" />
</selector>

Noe try this on your button.

int imgID = getResources().getIdentifier("button_pressed", "drawable", getApplication().getPackageName());
button.setImageResource(imgID);

button_pressed.xml should be in the drawable folder. icon_1_press and icon_1 are two images for button press and normal focus.

    File files = new File("src");
    // src is folder name...
    //This will return the list of the subDirectories
    List<File> subDirectories = Arrays.stream(files.listFiles()).filter(File::isDirectory).collect(Collectors.toList());

I would say echo() ing them directly into the Javascript source code is the most reliable and downward compatible way. Stay with that unless you have a good reason not to.

i have ran into the same problem and found a solution (not totally by myself, but there is the internet for)

Color blue  = ColorTranslator.FromHtml("#CCFFFF");
Color red = ColorTranslator.FromHtml("#FFCCFF");
Color letters = Color.Black;

foreach (DataGridViewRow r in datagridIncome.Rows)
{
    if (r.Cells[5].Value.ToString().Contains("1")) { 
        r.DefaultCellStyle.BackColor = blue;
        r.DefaultCellStyle.SelectionBackColor = blue;
        r.DefaultCellStyle.SelectionForeColor = letters;
    }
    else { 
        r.DefaultCellStyle.BackColor = red;
        r.DefaultCellStyle.SelectionBackColor = red;
        r.DefaultCellStyle.SelectionForeColor = letters;
    }
}

This is a small trick, the only way you can see a row is selected, is by the very first column (not column[0], but the one therefore). When you click another row, you will not see the blue selection anymore, only the arrow indicates which row have selected. As you understand, I use rowSelection in my gridview.

(I'm not allowed to comment yet.) I would suggest the following improvements to the already great answer of James McNellis:

template <typename Enumeration>
constexpr auto as_integer(Enumeration const value)
    -> typename std::underlying_type<Enumeration>::type
{
    static_assert(std::is_enum<Enumeration>::value, "parameter is not of type enum or enum class");
    return static_cast<typename std::underlying_type<Enumeration>::type>(value);
}

with

• constexpr: allowing me to use an enum member value as compile-time array size
• static_assert+is_enum: to 'ensure' compile-time that the function does sth. with enumerations only, as suggested

By the way I'm asking myself: Why should I ever use enum class when I would like to assign number values to my enum members?! Considering the conversion effort.

Perhaps I would then go back to ordinary enum as I suggested here: How to use enums as flags in C++?

Yet another (better) flavor of it without static_assert, based on a suggestion of @TobySpeight:

template <typename Enumeration>
constexpr std::enable_if_t<std::is_enum<Enumeration>::value,
std::underlying_type_t<Enumeration>> as_number(const Enumeration value)
{
    return static_cast<std::underlying_type_t<Enumeration>>(value);
}

MediaElement YouTube API example

Wraps the YouTube API in an HTML5 Media API wrapper, so that it can be programmed against as if it was true HTML5 <video>.

<script src="jquery.js"></script>
<script src="mediaelement-and-player.min.js"></script>
<link rel="stylesheet" href="mediaelementplayer.css" />

<video width="640" height="360" id="player1" preload="none">
    <source type="video/youtube" src="http://www.youtube.com/watch?v=nOEw9iiopwI" />
</video>

<script>
    var player = new MediaElementPlayer('#player1');
</script>

You are actually here touching two questions in one.

The first one is How to host your application?.
And as @toskv mentioned its really too broad question to be answered and depends on numerous different things.

The second one is How do you prepare the deployment version of the application?.
You have several options here:

1. Deploy as it is. Just that - no minification, concatenation, name mangling, etc. Transpile all your ts project copy all your resulting js/css/... sources + dependencies to the hosting server and you are good to go.

2. Deploy using special bundling tools, like webpack or systemjs builder.
   They come with all the possibilities that are lacking in #1.
   You can pack all your app code into just a couple of js/css/... files that you reference in your HTML. systemjs builder even allows you to get rid of the need to include systemjs as part of your deployment package.

3. You can use ng deploy as of Angular 8 to deploy your app from your CLI. ng deploy will need to be used in conjunction with your platform of choice (such as @angular/fire). You can check the official docs to see what works best for you here

Yes you will most likely need to deploy systemjs and bunch of other external libraries as part of your package. And yes you will be able to bundle them into just couple of js files you reference from your HTML page.

You do not have to reference all your compiled js files from the page though - systemjs as a module loader will take care of that.

I know it sounds muddy - to help get you started with the #2 here are two really good sample applications:

SystemJS builder: angular2 seed

WebPack: angular2 webpack starter

You can escape the dot and other special characters using \

eg. grep -r "0\.49"

In C++11 you can. A note beforehand: Don't new the array, there's no need for that.

First, string[] strArray is a syntax error, that should either be string* strArray or string strArray[]. And I assume that it's just for the sake of the example that you don't pass any size parameter.

#include <string>

void foo(std::string* strArray, unsigned size){
  // do stuff...
}

template<class T>
using alias = T;

int main(){
  foo(alias<std::string[]>{"hi", "there"}, 2);
}

Note that it would be better if you didn't need to pass the array size as an extra parameter, and thankfully there is a way: Templates!

template<unsigned N>
void foo(int const (&arr)[N]){
  // ...
}

Note that this will only match stack arrays, like int x[5] = .... Or temporary ones, created by the use of alias above.

int main(){
  foo(alias<int[]>{1, 2, 3});
}

require is part of the Asynchronous Module Definition (AMD) API.

A browser implementation can be found via require.js and native support can be found in node.js.

The documentation for the library you are using should tell you what you need to use it, I suspect that it is intended to run under Node.js and not in browsers.

If you don't want to place the watch inside a specific controller, you can add the watch for the whole aplication in Angular app run()

var myApp = angular.module('myApp', []);

myApp.run(function($rootScope) {
    $rootScope.$on("$locationChangeStart", function(event, next, current) { 
        // handle route changes     
    });
});

I had same issue while moving from AWS to Azure

For express & aws, you can already use, existing time() and timeEnd()

For Azure, use this: https://github.com/manoharreddyporeddy/my-nodejs-notes/blob/master/performance_timers_helper_nodejs_azure_aws.js

These time() and timeEnd() use the existing hrtime() function, which give high-resolution real time.

Hope this helps.

Cascading is biting you. Try this:

.menu > .main-nav-item:hover
    {
        color:#DDD;
    }

This code says to grab all the links that have a class of main-nav-item AND are children of the class menu, and apply the color #DDD when they are hovered.

Can also use here document and vi, the below script generates a FILE.txt with 3 lines and variable interpolation

VAR=Test
vi FILE.txt <<EOFXX
i
#This is my var in text file
var = $VAR
#Thats end of text file
^[
ZZ
EOFXX

Then file will have 3 lines as below. "i" is to start vi insert mode and similarly to close the file with Esc and ZZ.

#This is my var in text file
var = Test
#Thats end of text file

This has nothing to do with the MIME type, but the Content-Disposition header, which should be something like:

Content-Disposition: attachment; filename=genome.jpeg;

Make sure it is actually correctly passed to the client (not filtered by the server, proxy or something). Also you could try to change the order of writing headers and set them before getting output stream.

For i = 2 To 24
  Level = Cells(i, 4)
  Return = Cells(i, 5)

  If Return = 0 And Level = 0 Then GoTo NextIteration
  'Go to the next iteration
  Else
  End If
  ' This is how you make a line label in VBA - Do not use keyword or
  ' integer and end it in colon
  NextIteration:
Next

I had the same problem and figured it out from your comments, but thought I would add the reason I caused the error to occur (for other beginners).

I had opened and edited .bash_profile using the open command in Terminal, which opened it in Text Editor. I typed in an addition to .bash_profile and it used improper quote characters. I opened .bash_profile in Atom and fixed up the error. I also associated the file with Atom for future editing.

.htpasswd entries are HASHES. They are not encrypted passwords. Hashes are designed not to be decryptable. Hence there is no way (unless you bruteforce for a loooong time) to get the password from the .htpasswd file.

What you need to do is apply the same hash algorithm to the password provided to you and compare it to the hash in the .htpasswd file. If the user and hash are the same then you're a go.

Can you clarify your question? What is "ohHover" in this case and how does it correspond to a delay in hover time?

That said, I think what you probably want is...

var timeout;
element.onmouseover = function(e) {
    timeout = setTimeout(function() {
        // ...
    }, delayTimeMs)
};
element.onmouseout = function(e) {
    if(timeout) {
        clearTimeout(timeout);
    }
};

Or addEventListener/attachEvent or your favorite library's event abstraction method.

I think this could help - CASE the columns value to NULL if it's duplicate - then it's not appended to LISTAGG string:

with test_data as 
(
      select 1 as col1, 2 as col2, 'Smith' as created_by from dual
union select 1, 2, 'John' from dual
union select 1, 3, 'Ajay' from dual
union select 1, 4, 'Ram' from dual
union select 1, 5, 'Jack' from dual
union select 2, 5, 'Smith' from dual
union select 2, 6, 'John' from dual
union select 2, 6, 'Ajay' from dual
union select 2, 6, 'Ram' from dual
union select 2, 7, 'Jack' from dual
)
SELECT col1  ,
      listagg(col2 , ',') within group (order by col2 ASC) AS orig_value,
      listagg(CASE WHEN rwn=1 THEN col2 END , ',') within group (order by col2 ASC) AS distinct_value
from 
    (
    select row_number() over (partition by col1,col2 order by 1) as rwn, 
           a.*
    from test_data a
    ) a
GROUP BY col1   

Results in:

COL1  ORIG         DISTINCT
1   2,2,3,4,5   2,3,4,5
2   5,6,6,6,7   5,6,7

when you set the density to 96, doesn't it look good?

when i tried it i saw that saving as jpg resulted with better quality, but larger file size

$('.UPDATE').click(function(){ }); **V/S**    
$(document).on('click','.UPDATE',function(){ });

$(document).on('click','.UPDATE',function(){ });

1. it is more effective then $('.UPDATE').click(function(){ });
2. it can use less memory and work for dynamically added elements.
3. some time dynamic fetched data with edit and delete button not generate JQuery event at time of EDIT OR DELETE DATA of row data in form, that time $(document).on('click','.UPDATE',function(){ }); is effectively work like same fetched data by using jquery. button not working at time of update or delete:

Short answer: set the maxWidth options property in the constructor. Yes, even if setting the maximum width was not what you wanted to do.

Longer story: Migrating a v2 map to v3, I saw exactly the problem described. Windows varied in width and height, and some had vertical scrollbars and some didn't. Some had <br /> embedded in the data, but at least one with that sized OK.

I didn't think the InfoWindowsOptions.maxWidth property was relevant, since I didn't care to constrain the width... but by setting it with the InfoWindow constructor, I got what I wanted, and the windows now autosize (vertically) and show the full content without a vertical scrollbar. Doesn't make a lot of sense to me, but it works!

Web application context, specified by the WebApplicationContext interface, is a Spring application context for a web applications. It has all the properties of a regular Spring application context, given that the WebApplicationContext interface extends the ApplicationContext interface, and add a method for retrieving the standard Servlet API ServletContext for the web application.

In addition to the standard Spring bean scopes singleton and prototype, there are three additional scopes available in a web application context:

• request - scopes a single bean definition to the lifecycle of a single HTTP request; that is, each HTTP request has its own instance of a bean created off the back of a single bean definition
• session - scopes a single bean definition to the lifecycle of an HTTP Session
• application - scopes a single bean definition to the lifecycle of a ServletContext

Quite amazing how all answers talk about IIS, as if that were the only web server that mattered. Even back in 2010 when the question was asked, Apache had between 60% and 70% of the market share. Anyway,

• The HTTP protocol does not specify a limit.
• The POST method allows sending far more data than the GET method, which is limited by the URL length - about 2KB.
• The maximum POST request body size is configured on the HTTP server and typically ranges from
  1MB to 2GB
• The HTTP client (browser or other user agent) can have its own limitations. Therefore, the maximum POST body request size is min(serverMaximumSize, clientMaximumSize).

Here are the POST body sizes for some of the more popular HTTP servers:

• Ngix (largest web server market share as of April 2019) - default 1MB, no practical maximum (2**63)
• Apache - maximum 2GB, no default documented
• IIS - default 28.6MB for the request length, 2048 bytes for the query string; maximum undocumented
• InfluxDB - default ~25MB, maximum undocumented

Path is often null. This function is safer.

You can use Future.delayed to run your code after some time. e.g.:

Future.delayed(const Duration(milliseconds: 500), () {

// Here you can write your code

  setState(() {
    // Here you can write your code for open new view
  });

});

In setState function, you can write a code which is related to app UI e.g. refresh screen data, change label text, etc.

Here is the jQuery function I use:

function isExists(var elemId){
    return jQuery('#'+elemId).length > 0;
}

This will return a boolean value. If element exists, it returns true. If you want to select element by class name, just replace # with .

I too found this perplexing. I'm running Ubuntu 18 and found the following: If the cv.imshow window has focus, you'll get one set of values in the terminal - like the ASCII values discussed above.

If the Terminal has focus, you'll see different values. IE- you'll see "a" when you press the a key (instead of ASCII value 97) and "^]" instead of "27" when you press Escape.

I didn't see the 6 digit numbers mentioned above in either case and I used similar code. It seems the value for waitKey is the polling period in mS. The dots illustrate this.

Run this snippet and press keys while focus is on the test image, then click on the terminal window and press the same keys.

    import cv2
    img = cv2.imread('test.jpg') 
    cv2.imshow('Your test image', img)

    while(1):
      k = cv2.waitKey(300)
      if k == 27:
        break
      elif k==-1:
       print "."
       continue
      else:
        print k 

Short and sweet

I'm not sure why none of the previous answers worked for me, but I came up with this solution during a eureka moment. It not only works, but it is also most elegant:

Add to body tag:

onmouseup="down=0;" onmousedown="down=1;"

Then test and execute myfunction() if down equals 1:

onmousemove="if (down==1) myfunction();"

As mentioned in the excellent answer by janoside, you need to construct the JSON string and set it as a StringEntity.

To construct the JSON string, you can use any library or method you are comfortable with. Jackson library is one easy example:

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.StringEntity;

ObjectMapper mapper = new ObjectMapper();
ObjectNode node = mapper.createObjectNode();
node.put("name", "value"); // repeat as needed
String JSON_STRING = node.toString();
postMethod.setEntity(new StringEntity(JSON_STRING, ContentType.APPLICATION_JSON));

I'm a relative novice compared to all the experts on Stack Overflow.

I have 2 versions of jupyter notebook running (one through a fresh Anaconda Navigator installation and one through ????). I think this is because Anaconda was installed as a local installation on my Mac (per Anaconda instructions).

I already had python 3.7 installed. After that, I used my terminal to open jupyter notebook and I think that it put another version globally onto my Mac.

However, I'm not sure because I'm just learning through trial and error!

I did the terminal command:

conda install -c anaconda certifi 

(as directed above, but it didn't work.)

My python 3.7 is installed on OS Catalina10.15.3 in:

• /Library/Python/3.7/site-packages AND
• ~/Library/Python/3.7/lib/python/site-packages

The certificate is at:

• ~/Library/Python/3.7/lib/python/site-packages/certifi-2019.11.28.dist-info

I tried to find the Install Certificate.command ... but couldn't find it through looking through the file structures...not in Applications...not in links above.

I finally installed it by finding it through Spotlight (as someone suggested above). And it double clicked automatically and installed ANOTHER certificate in the same folder as:

• ~/Library/Python/3.7/lib/python/site-packages/

NONE of the above solved anything for me...I still got the same error.

So, I solved the problem by:

1. closing my jupyter notebook.
2. opening Anaconda Navigator.
3. opening jupyter notebook through the Navigator GUI (instead of through Terminal).
4. opening my notebook and running the code.

I can't tell you why this worked. But it solved the problem for me.

I just want to save someone the hassle next time. If someone can tell my why it worked, that would be terrific.

I didn't try the other terminal commands because of the 2 versions of jupyter notebook that I knew were a problem. I just don't know how to fix that.

If nothing helps and you are still getting this exception, review your equals() methods - and don't include child collection in it. Especially if you have deep structure of embedded collections (e.g. A contains Bs, B contains Cs, etc.).

In example of Account -> Transactions:

  public class Account {

    private Long id;
    private String accountName;
    private Set<Transaction> transactions;

    @Override
    public boolean equals(Object obj) {
      if (this == obj)
        return true;
      if (obj == null)
        return false;
      if (!(obj instanceof Account))
        return false;
      Account other = (Account) obj;
      return Objects.equals(this.id, other.id)
          && Objects.equals(this.accountName, other.accountName)
          && Objects.equals(this.transactions, other.transactions); // <--- REMOVE THIS!
    }
  }

In above example remove transactions from equals() checks. This is because hibernate will imply that you are not trying to update old object, but you pass a new object to persist, whenever you change element on the child collection.
Of course this solutions will not fit all applications and you should carefully design what you want to include in the equals and hashCode methods.

Might be answer is late but look at Simple Information of SKU (Stock keeping unit) number is, it's an unique tracking number (an arbi­trary num­ber) that are used in appStore for your application. You can put what­ever you want in there as long as it is unique among your appli­ca­tions. Try to fol­low a pat­tern for the SKU Num­ber of your apps so that you will be able to bet­ter orga­nize them. I sug­gest a com­bi­na­tion of the cur­rent year + month + ID for your app. So if you’re devel­op­ing your first appli­ca­tion on september 1991 (oh,, yah it's my b'day's month and year :D ), you could put your SKU Num­ber as “19910901”. Here, I am just suggesting you for this pattern but you can take/choose any pattern which easy for you.

Since search engines ignore most javascript, you will need to make it so that search engines can crawl using the tabs without using Ajax. Make each tab a link with an href that loads the entire page with that tab selected. Then the page can have that title in the tag.

The onclick event handler can still load the pages via ajax for human viewers.

To see the pages as most search engines see them, turn off Javascript in your browser, and try to make it so that clicking the tabs will load the page with that tab selected and the correct title.

If you are loading via ajax and you want to dynamically change the page title with just Javascript, then do:

document.title = 'Put the new title here';

However, search engines will not see this change made in javascript.

I'd like to add to my preposter. I suggest a slightly different approach that will allow you to simply assign a new value to your object without using a method. It must be noted though that this is not supported by especially older browsers and IE9 still requires use of a different interface.

Most notably is that my approach does not make use of events.

Getters and Setters

My proposal makes use of the relatively young feature of getters and setters, particularly setters only. Generally speaking, mutators allow us to "customize" the behavior of how certain properties are assigned a value and retrieved.

One implementation I'll be using here is the Object.defineProperty method. It works in FireFox, GoogleChrome and - I think - IE9. Haven't tested other browsers, but since this is theory only...

Anyways, it accepts three parameters. The first parameter being the object that you wish to define a new property for, the second a string resembling the the name of the new property and the last a "descriptor object" providing information on the behavior of the new property.

Two particularly interesting descriptors are get and set. An example would look something like the following. Note that using these two prohibits the use of the other 4 descriptors.

function MyCtor( bindTo ) {
    // I'll omit parameter validation here.

    Object.defineProperty(this, 'value', {
        enumerable: true,
        get : function ( ) {
            return bindTo.value;
        },
        set : function ( val ) {
            bindTo.value = val;
        }
    });
}

Now making use of this becomes slightly different:

var obj = new MyCtor(document.getElementById('foo')),
    i = 0;
setInterval(function() {
    obj.value += ++i;
}, 3000);

I want to emphasize that this only works for modern browsers.

Working fiddle: http://jsfiddle.net/Derija93/RkTMD/1/

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

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

or if you can configure your view resolver something like,

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

then just return

return "RANDOM-FILENAME";

Another way around this would be to insert a DEFAULT element in the other table. For example, any reference to uuid=00000000-0000-0000-0000-000000000000 on the other table would indicate no action. You also need to set all the values for that id to be "neutral", e.g. 0, empty string, null in order to not affect your code logic.

I've developed my own MySQL escape method in Java (if useful for anyone).

See class code below.

Warning: wrong if NO_BACKSLASH_ESCAPES SQL mode is enabled.

private static final HashMap<String,String> sqlTokens;
private static Pattern sqlTokenPattern;

static
{           
    //MySQL escape sequences: http://dev.mysql.com/doc/refman/5.1/en/string-syntax.html
    String[][] search_regex_replacement = new String[][]
    {
                //search string     search regex        sql replacement regex
            {   "\u0000"    ,       "\\x00"     ,       "\\\\0"     },
            {   "'"         ,       "'"         ,       "\\\\'"     },
            {   "\""        ,       "\""        ,       "\\\\\""    },
            {   "\b"        ,       "\\x08"     ,       "\\\\b"     },
            {   "\n"        ,       "\\n"       ,       "\\\\n"     },
            {   "\r"        ,       "\\r"       ,       "\\\\r"     },
            {   "\t"        ,       "\\t"       ,       "\\\\t"     },
            {   "\u001A"    ,       "\\x1A"     ,       "\\\\Z"     },
            {   "\\"        ,       "\\\\"      ,       "\\\\\\\\"  }
    };

    sqlTokens = new HashMap<String,String>();
    String patternStr = "";
    for (String[] srr : search_regex_replacement)
    {
        sqlTokens.put(srr[0], srr[2]);
        patternStr += (patternStr.isEmpty() ? "" : "|") + srr[1];            
    }
    sqlTokenPattern = Pattern.compile('(' + patternStr + ')');
}


public static String escape(String s)
{
    Matcher matcher = sqlTokenPattern.matcher(s);
    StringBuffer sb = new StringBuffer();
    while(matcher.find())
    {
        matcher.appendReplacement(sb, sqlTokens.get(matcher.group(1)));
    }
    matcher.appendTail(sb);
    return sb.toString();
}

The suggestion from @Dawood is good if that works for you.

If you need more fine-tuning than that, one option is to use padding on the text elements, here's an example: http://jsfiddle.net/panchroma/FtBwe/

CSS

p, h2 {
    padding-left:10px;
}

string[] lines = File.ReadLines("c:\\file.txt").ToArray();

Although one wonders why you'll want to do that when ReadAllLines works just fine.

Or perhaps you just want to enumerate with the return value of File.ReadLines:

var lines = File.ReadAllLines("c:\\file.txt");
foreach (var line in lines)
{
    Console.WriteLine("\t" + line);
}

Be careful if you are using continuous integration, you must add your libraries in the same path on your build server.

For this reason, I'd rather add jar to the local repository and, of course, do the same on the build server.

1. if it's tab delimited txt file:

LOAD DATA LOCAL INFILE 'D:/MySQL/event.txt' INTO TABLE event

LINES TERMINATED BY '\r\n';

2. otherwise:

LOAD DATA LOCAL INFILE 'D:/MySQL/event.txt' INTO TABLE event

FIELDS TERMINATED BY 'x' (here x could be comma ',', tab '\t', semicolon ';', space ' ')

LINES TERMINATED BY '\r\n';

Below works for first tr of the table under thead

table thead tr:first-child {
   background: #f2f2f2;
}

And this works for the first tr of thead and tbody both:

table thead tbody tr:first-child {
   background: #f2f2f2;
}

Given an array you can use the Array.ConvertAll method:

int[] myInts = Array.ConvertAll(arr, s => int.Parse(s));

Thanks to Marc Gravell for pointing out that the lambda can be omitted, yielding a shorter version shown below:

int[] myInts = Array.ConvertAll(arr, int.Parse);

A LINQ solution is similar, except you would need the extra ToArray call to get an array:

int[] myInts = arr.Select(int.Parse).ToArray();

use

str.isalpha() 

Ref: https://docs.python.org/2/library/stdtypes.html#str.isalpha

Return true if all characters in the string are alphabetic and there is at least one character, false otherwise.

In Angular 7.X

The CSS classes are updated as follows, depending on the type of the expression evaluation:

• string - the CSS classes listed in the string (space delimited) are added

• Array - the CSS classes declared as Array elements are added

• Object - keys are CSS classes that get added when the expression given in the value evaluates to a truthy value, otherwise they are removed.

Queue is an interface that extends Collection in Java. It has all the functions needed to support FIFO architecture.

For concrete implementation you may use LinkedList. LinkedList implements Deque which in turn implements Queue. All of these are a part of java.util package.

For details about method with sample example you can refer FIFO based Queue implementation in Java.

PS: Above link goes to my personal blog that has additional details on this.

A bit late, but perhaps someone will find it useful.

Links that fix the problem (you must be logged into google account):

https://security.google.com/settings/security/activity?hl=en&pli=1

https://www.google.com/settings/u/1/security/lesssecureapps

https://accounts.google.com/b/0/DisplayUnlockCaptcha

Some explanation of what happens:

This problem can be caused by either 'less secure' applications trying to use the email account (this is according to google help, not sure how they judge what is secure and what is not) OR if you are trying to login several time in a row OR if you change countries (for example use VPN, move code to different server or actually try to login from different part of the world).

To resolve I had to: (first time)

• login to my account via web
• view recent attempts to use the account and accept suspicious access: THIS LINK
• disable the feature of blocking suspicious apps/technologies: THIS LINK

This worked the first time, but few hours later, probably because I was doing a lot of testing the problem reappeared and was not fixable using the above method. In addition I had to clear the captcha (the funny picture, which asks you to rewrite a word or a sentence when logging into any account nowadays too many times) :

• after login to my account I went HERE
• Clicked continue

Hope this helps.

I would go with this one (C#):

static long LCM(long[] numbers)
{
    return numbers.Aggregate(lcm);
}
static long lcm(long a, long b)
{
    return Math.Abs(a * b) / GCD(a, b);
}
static long GCD(long a, long b)
{
    return b == 0 ? a : GCD(b, a % b);
}

Just some clarifications, because at first glance it doesn't seams so clear what this code is doing:

Aggregate is a Linq Extension method, so you cant forget to add using System.Linq to your references.

Aggregate gets an accumulating function so we can make use of the property lcm(a,b,c) = lcm(a,lcm(b,c)) over an IEnumerable. More on Aggregate

GCD calculation makes use of the Euclidean algorithm.

lcm calculation uses Abs(a*b)/gcd(a,b) , refer to Reduction by the greatest common divisor.

Omitting the header above the divider produces a headerless table in at least Perl Text::MultiMarkdown and in FletcherPenney MultiMarkdown

|-------------|--------|

See PHP Markdown feature request

Empty headers in PHP Parsedown produce tables with empty headers that are usually invisible (depending on your CSS) and so look like headerless tables.

You can just do that too, it seems to work well too. sc create "Servicename" binPath= "Path\To\your\App.exe" DisplayName= "My Custom Service"

You can open the registry and add a string named Description in your service's registry key to add a little more descriptive information about it. It will be shown in services.msc.

One major difference is that DataSets can hold multiple tables and you can define relationships between those tables.

If you are only returning a single result set though I would think a DataTable would be more optimized. I would think there has to be some overhead (granted small) to offer the functionality a DataSet does and keep track of multiple DataTables.

for i in range(100):
try:
  #Your code here
  break

This one worked for me.

You are getting confused with transclude: true, which would append the inner content.

replace: true means that the content of the directive template will replace the element that the directive is declared on, in this case the <div myd1> tag.

http://plnkr.co/edit/k9qSx15fhSZRMwgAIMP4?p=preview

For example without replace:true

<div myd1><span class="replaced" myd1="">directive template1</span></div>

and with replace:true

<span class="replaced" myd1="">directive template1</span>

As you can see in the latter example, the div tag is indeed replaced.

div[disabled]
{
  pointer-events: none;
  opacity: 0.7;
}

The above code makes the contents of the div disabled. You can make div disabled by adding disabled attribute.

<div disabled>
  /* Contents */
</div>

        }
    }

    @IBInspectable var borderWidth: CGFloat = 0.5 {
        didSet {
            setup()
        }
    }

    func setup() {
        border.borderColor = self.borderColor?.cgColor

        border.borderWidth = borderWidth
        self.layer.addSublayer(border)
        self.layer.masksToBounds = true
    }

    override func layoutSubviews() {
        super.layoutSubviews()
        border.frame = CGRect(x: 0, y: self.frame.size.height - borderWidth, width:  self.frame.size.width, height: self.frame.size.height)
    }
 }

If you like the idea of Views, but are worried about performance you can get Oracle to create a cached table representing the view which oracle keeps up to date.
See materialized views

There is a way without flexbox, although you'd need to meet the following conditions. 1) The container has padding. 2) Items are the same size and you know exactly how many you want per line.

ul {
  padding: 0 3% 0 5%;
}
li {
  display: inline-block; 
  padding: 0 2% 2% 0;
  width: 28.66%;
}

The smaller padding on the right side of the container allows for the extra padding to the right of each list item. Assuming other items in the same parent as the list object are padded with 0 5%, it will be flush with them. You can also adjust the percentages to however much margin you'd like or use calculate px values.

Of course, you can do the same without the padding on the container by using nth-child (IE 9+) to remove margin on every third box.

Way more elegant solution than $parent.$index is using ng-init:

<ul ng-repeat="section in sections" ng-init="sectionIndex = $index">
    <li  class="section_title {{section.active}}" >
        {{section.name}}
    </li>
    <ul>
        <li class="tutorial_title {{tutorial.active}}" ng-click="loadFromMenu(sectionIndex)" ng-repeat="tutorial in section.tutorials">
            {{tutorial.name}}
        </li>
    </ul>
</ul>

It is now possible with the HTML5 webapp manifest. See below.

Original answer:

You can't lock a website or a web application in a specific orientation. It goes against the natural behaviour of the device.

You can detect the device orientation with CSS3 media queries like this:

@media screen and (orientation:portrait) {
    // CSS applied when the device is in portrait mode
}

@media screen and (orientation:landscape) {
    // CSS applied when the device is in landscape mode
}

Or by binding a JavaScript orientation change event like this:

document.addEventListener("orientationchange", function(event){
    switch(window.orientation) 
    {  
        case -90: case 90:
            /* Device is in landscape mode */
            break; 
        default:
            /* Device is in portrait mode */
    }
});

Update on November 12, 2014: It is now possible with the HTML5 webapp manifest.

As explained on html5rocks.com, you can now force the orientation mode using a manifest.json file.

You need to include those line into the json file:

{
    "display":      "standalone", /* Could be "fullscreen", "standalone", "minimal-ui", or "browser" */
    "orientation":  "landscape", /* Could be "landscape" or "portrait" */
    ...
}

And you need to include the manifest into your html file like this:

<link rel="manifest" href="manifest.json">

Not exactly sure what the support is on the webapp manifest for locking orientation mode, but Chrome is definitely there. Will update when I have the info.

Consider a example where I have two databases namely allmsa.db and atlanta.db. Say the database allmsa.db has tables for all msas in US and database atlanta.db is empty.

Our target is to copy the table atlanta from allmsa.db to atlanta.db.

Steps

1. sqlite3 atlanta.db(to go into atlanta database)
2. Attach allmsa.db. This can be done using the command ATTACH '/mnt/fastaccessDS/core/csv/allmsa.db' AS AM; note that we give the entire path of the database to be attached.
3. check the database list using sqlite> .databases you can see the output as

seq  name             file                                                      
---  ---------------  ----------------------------------------------------------
0    main             /mnt/fastaccessDS/core/csv/atlanta.db                  
2    AM               /mnt/fastaccessDS/core/csv/allmsa.db 

4. now you come to your actual target. Use the command INSERT INTO atlanta SELECT * FROM AM.atlanta;

This should serve your purpose.

Upgrade to React Native 0.58.5 or higher version. They have includeSubdomain in their config files in RN 0.58.5.

ChangeLog

In Rn 0.58.5 they have declared network_security_config with their server domain. Network security configuration allows an app to permit cleartext traffic from a certain domain. So no need to put extra effort by declaring android:usesCleartextTraffic="true" in the application tag of your manifest file. It will be resolved automatically after upgrading the RN Version.

add a space character too the string. that's poor man's padding :)

OR

I would go with a custom background view but if you don't want that, the space is the only other easy options I see...

OR write a custom label. render the text via coretext

You can use http_build_query() to do that.

Generates a URL-encoded query string from the associative (or indexed) array provided.

It's all about editing the cell, the problem that is the cell didn't edited actually, so you need to save The changes of the cell or the row to get the event when you click the check box so you can use this function:

datagridview.CommitEdit(DataGridViewDataErrorContexts.CurrentCellChange)

with this you can use it even with a different event.

You are dealing with a HttpPostedFile; this is the file that is "uploaded" to the web server. You really need to save that file somewhere and then use it, because...

...in your instance, it just so happens to be that you are hosting your website on the same machine the file resides, so the path is accessible. As soon as you deploy your site to a different machine, your code isn't going to work.

Break this down into two steps:

1) Save the file somewhere - it's very common to see this:

string saveFolder = @"C:\temp\uploads"; //Pick a folder on your machine to store the uploaded files

string filePath = Path.Combine(saveFolder, FileUpload1.FileName); 

FileUpload1.SaveAs(filePath);

Now you have your file locally and the real work can be done.

2) Get the data from the file. Your code should work as is but you can simply write your connection string this way:

string excelConnString = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties="Excel 12.0";", filePath);

You can then think about deleting the file you've just uploaded and imported.

To provide a more concrete example, we can refactor your code into two methods:

    private void SaveFileToDatabase(string filePath)
    {
        String strConnection = "Data Source=.\\SQLEXPRESS;AttachDbFilename='C:\\Users\\Hemant\\documents\\visual studio 2010\\Projects\\CRMdata\\CRMdata\\App_Data\\Database1.mdf';Integrated Security=True;User Instance=True";

        String excelConnString = String.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0\"", filePath);
        //Create Connection to Excel work book 
        using (OleDbConnection excelConnection = new OleDbConnection(excelConnString))
        {
            //Create OleDbCommand to fetch data from Excel 
            using (OleDbCommand cmd = new OleDbCommand("Select [ID],[Name],[Designation] from [Sheet1$]", excelConnection))
            {
                excelConnection.Open();
                using (OleDbDataReader dReader = cmd.ExecuteReader())
                {
                    using(SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection))
                    {
                        //Give your Destination table name 
                        sqlBulk.DestinationTableName = "Excel_table";
                        sqlBulk.WriteToServer(dReader);
                    }
                }
            }
        } 
    }


    private string GetLocalFilePath(string saveDirectory, FileUpload fileUploadControl)
    {


        string filePath = Path.Combine(saveDirectory, fileUploadControl.FileName);

        fileUploadControl.SaveAs(filePath);

        return filePath;

    }

You could simply then call SaveFileToDatabase(GetLocalFilePath(@"C:\temp\uploads", FileUpload1));

Consider reviewing the other Extended Properties for your Excel connection string. They come in useful!

Other improvements you might want to make include putting your Sql Database connection string into config, and adding proper exception handling. Please consider this example for demonstration only!

I really needed the call to originate from the get method, due to my decoupled architecture. So I came up with the following implementation.

Usage: Title is in a ViewModel or an object you could statically declare as a page resource. Bind to it and the value will get populated without blocking the UI, when getTitle() returns.

string _Title;
public string Title
{
    get
    {
        if (_Title == null)
        {   
            Deployment.Current.Dispatcher.InvokeAsync(async () => { Title = await getTitle(); });
        }
        return _Title;
    }
    set
    {
        if (value != _Title)
        {
            _Title = value;
            RaisePropertyChanged("Title");
        }
    }
}

use this code

var sid = $(this);
sid.attr('checked','checked');

My problem was unrelated to processData. It was because I sent a function that cannot be called later with apply because it did not have enough arguments. Specifically I shouldn't have used alert as the error callback.

$.ajax({
    url: csvApi,
    success: parseCsvs,
    dataType: "json",
    timeout: 5000,
    processData: false,
    error: alert
});

See this answer for more information on why that can be a problem: Why are certain function calls termed "illegal invocations" in JavaScript?

The way I was able to discover this was by adding a console.log(list[ firingIndex ]) to jQuery so I could track what it was firing.

This was the fix:

function myError(jqx, textStatus, errStr) {
    alert(errStr);
}

$.ajax({
    url: csvApi,
    success: parseCsvs,
    dataType: "json",
    timeout: 5000,
    error: myError // Note that passing `alert` instead can cause a "jquery.js:3189 Uncaught TypeError: Illegal invocation" sometimes
});

You can try this:

var a = Array<Int>(5){0}

You can pull apps with ADB. They are in /data/App/, I believe.

adb pull (location on device) (where to save)

Note that you have to root your phone to pull copy protected apps.

In my case, it's caused by wrong configuration of the requested server's address.

The server address should be an FQDN (fully qualified domain name).

FQDN is always required by Kerberos.

$ dseditgroup -o edit -u <adminusername> -t user -a <developerusername> _developer

Json.NET has a JsonPropertyAttribute which allows you to specify the name of a JSON property, so your code should be:

public class TeamScore
{
    [JsonProperty("eighty_min_score")]
    public string EightyMinScore { get; set; }
    [JsonProperty("home_or_away")]
    public string HomeOrAway { get; set; }
    [JsonProperty("score ")]
    public string Score { get; set; }
    [JsonProperty("team_id")]
    public string TeamId { get; set; }
}

public class Team
{
    public string v1 { get; set; }
    [JsonProperty("attributes")]
    public TeamScore TeamScores { get; set; }
}

public class RootObject
{
    public List<Team> Team { get; set; }
}

We had the same issue, working from JS code (i.e. not from HTML anchor). This is how we solved that:

1. If needed, virtually alter current URL through $location service. This might be useful if your destination is just a variation on the current URL, so that you can take advantage of $location helper methods. E.g. we ran $location.search(..., ...) to just change value of a querystring paramater.

2. Build up the new destination URL, using current $location.url() if needed. In order to work, this new one had to include everything after schema, domain and port. So e.g. if you want to move to:

   http://yourdomain.com/YourAppFolder/YourAngularApp/#/YourArea/YourAction?culture=en

   then you should set URL as in:

   var destinationUrl = '/YourAppFolder/YourAngularApp/#/YourArea/YourAction?culture=en';

   (with the leading '/' as well).

3. Assign new destination URL at low-level: $window.location.href = destinationUrl;

4. Force reload, still at low-level: $window.location.reload();

In addition to Reed Copsey's answer:

• The worst case is where the two files are identical. In this case it's best to compare the files byte-by-byte.

• If if the two files are not identical, you can speed things up a bit by detecting sooner that they're not identical.

For example, if the two files are of different length then you know they cannot be identical, and you don't even have to compare their actual content.

The NameVirtualHost option would be a good option.

Simply works as:

$("a. close").live("click",function(event){
     return confirm("Do you want to delete?");
});

I'm a little late to the party, but...

[].some(x => !!x)

There's an even simpler answer if you want to delete ALL your tables. You just go to your folder containing the database (which may be called mydatabase.db) and right-click the .db file and push "delete." Old fashioned way, sure-fire to work.

Don't forget to specify mapping information in .config file

e.g.

where MyApp.Data is assembly that contains your mappings

See if the BSD C Standard Library has fcvt(). You could start with the source for it that rather than writing your code from scratch. The UNIX 98 standard fcvt() apparently does not output scientific notation so you would have to implement it yourself, but I don't think it would be hard.

First treat the number like a string

number = 9876543210
number = str(number)

Then to get the first digit:

number[0]

The fourth digit:

number[3]

EDIT:

This will return the digit as a character, not as a number. To convert it back use:

int(number[0])

Assuming the simplest option (installing rsync on the remote host) isn't feasible, you can use sshfs to mount the remote locally, and rsync from the mount directory. That way you can use all the options rsync offers, for example --exclude.

Something like this should do:

sshfs user@server: sshfsdir
rsync --recursive --exclude=whatever sshfsdir/path/on/server /where/to/store

Note that the effectiveness of rsync (only transferring changes, not everything) doesn't apply here. This is because for that to work, rsync must read every file's contents to see what has changed. However, as rsync runs only on one host, the whole file must be transferred there (by sshfs). Excluded files should not be transferred, however.

"End Process" on the Processes-Tab calls TerminateProcess which is the most ultimate way Windows knows to kill a process.

If it doesn't go away, it's currently locked waiting on some kernel resource (probably a buggy driver) and there is nothing (short of a reboot) you could do to make the process go away.

Have a look at this blog-entry from wayback when: http://blogs.technet.com/markrussinovich/archive/2005/08/17/unkillable-processes.aspx

Unix based systems like Linux also have that problem where processes could survive a kill -9 if they are in what's known as "Uninterruptible sleep" (shown by top and ps as state D) at which point the processes sleep so well that they can't process incoming signals (which is what kill does - sending signals).

Normally, Uninterruptible sleep should not last long, but as under Windows, broken drivers or broken userpace programs (vfork without exec) can end up sleeping in D forever.

Add the border to each cell with this:

table > tbody > tr > td { border: 1px solid rgba(255, 255, 255, 0.1); }

Remove the top border from all the cells in the first row:

table > tbody > tr:first-child > td { border-top: 0; }

Remove the left border from the cells in the first column:

table > tbody > tr > td:first-child { border-left: 0; }

Remove the right border from the cells in the last column:

table > tbody > tr > td:last-child { border-right: 0; }

Remove the bottom border from the cells in the last row:

table > tbody > tr:last-child > td { border-bottom: 0; }

You can try something like:

var str = "a,d,k";
str.replace(/,/g, "");

UPDATE table
SET A = IF(A > 0 AND A < 1, 1, IF(A > 1 AND A < 2, 2, A))
WHERE A IS NOT NULL;

you might want to use CEIL() if A is always a floating point value > 0 and <= 2

I think a lot of times when you see this code, it's from people who are in the habit of event handlers for forms, buttons, inputs, and things of that sort.

Basically, when you have something like:

<form onsubmit="return callSomeFunction();"></form>

or

<a href="#" onclick="return callSomeFunction();"></a>`

and callSomeFunction() returns true, then the form or a will submit, otherwise it won't.

Other more obvious general purposes for returning true or false as a result of a function are because they are expected to return a boolean.

Just chain them together:

.a.b {
  color: #666;
}

In your implementation you are missing static Class, this should be.

if (!ModelState.IsValid)
{
    var errors =  ModelStateErrorHandler.GetModelErrors(this.ModelState);
    return Json(new { errors });
}

rather

if (!ModelState.IsValid)
{
    var errors = ModelState.GetModelErrors();
    return Json(new { errors });
}

The solution I use for large sql restore is a mysqldumpsplitter script. I split my sql.gz into individual tables. then load up something like mysql workbench and process it as a restore to the desired schema.

Here is the script https://github.com/kedarvj/mysqldumpsplitter

And this works for larger sql restores, my average on one site I work with is a 2.5gb sql.gz file, 20GB uncompressed, and ~100Gb once restored fully

You want exactly this:

BASE_DIR = os.path.join( os.path.dirname( __file__ ), '..' )

There are a few encodings that can be used to de-/encode from str to str or from unicode to unicode. For example base64, hex or even rot13. They are listed in the codecs module.

Edit:

The decode message on a unicode string can undo the corresponding encode operation:

In [1]: u'0a'.decode('hex')
Out[1]: '\n'

The returned type is str instead of unicode which is unfortunate in my opinion. But when you are not doing a proper en-/decode between str and unicode this looks like a mess anyway.

Entity-Framework Select Distinct Name:

Suppose if you are using Views in which you are using multiple tables and you want to apply distinct in that case first you have to store value in variable & then you can apply Distinct on that variable like this one....

public List<Item_Img_Sal_VIEW> GetItemDescription(int ItemNo) 
        {
            var Result= db.Item_Img_Sal_VIEW.Where(p => p.ItemID == ItemNo).ToList();
            return Result.Distinct().ToList();
        }

Or you can try this Simple Example

Public Function GetUniqueLocation() As List(Of Integer)
          Return db.LoginUsers.Select(Function(p) p.LocID).Distinct().ToList()
End Function

Open your run configurations
Click on the jUnit-Test you want to start
go to the classpath tab
Try to add a folder (click on user entries, click on advanced, click on add folders,click on ok and search the outputfolder for your test classes(those you find under projektproperties java build path, source))

worked after

Maven 2 LifeCycle >> test

try:
  #treat object as iterable
except TypeError, e:
  #object is not actually iterable

Don't run checks to see if your duck really is a duck to see if it is iterable or not, treat it as if it was and complain if it wasn't.

If you're doing fragment caching, you can manually break the cache by updating your cache key, like so:

Version #1

<% cache ['cool_name_for_cache_key', 'v1'] do %>

Version #2

<% cache ['cool_name_for_cache_key', 'v2'] do %>

Or you can have the cache automatically reset based on the state of a non-static object, such as an ActiveRecord object, like so:

<% cache @user_object do %>

With this ^ method, any time the user object is updated, the cache will automatically be reset.

I just discovered this: https://greek0.net/boost-range/boost-adaptors-indexed.html

    for (const auto & element : str | boost::adaptors::indexed(0)) {
        std::cout << element.index()
                  << " : "
                  << element.value()
                  << std::endl;
    }

For example if you want to do diferent things depending on the value of a variable:

my_var = 1
for items in range(0,100):
    if my_var < 10:
        continue
    elif my_var == 10:
        print("hit")
    elif my_var > 10:
        print("passed")
    my_var = my_var + 1

In the example above if I use break the interpreter will skip the loop. But with continueit only skips the if-elif statements and go directly to the next item of the loop.

Just use dynamic as the argument:

var list = new List<dynamic>();

This is actually on the main page of nltk.org:

'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']

I got this error when using GroupBy via LINQ on a MySQL database. The problem was that the anonymous object property that was being used by GroupBy did not match the database column name. Fixed by renaming anonymous property name to match the column name.

.Select(f => new 
{
   ThisPropertyNameNeedsToMatchYourColumnName = f.SomeName
})
.GroupBy(t => t.ThisPropertyNameNeedsToMatchYourColumnName);

According to this Video if you use the ProGuard you don't need even think about Enums performance issues!!

Proguard can in many situations optimize Enums to INT values on your behalf so really don't need to think about it or do any work.

Here is what I've done to run the emulator quickly in windows : I've created a windows batch file like this :

start C:\Users\{Username}\AppData\Local\Android\Sdk\tools\emulator.exe -avd {Emulator_Name}

and just run the batch file every time I need the emulator.

Yet another cause and solution to this: Check that you didn't put a space in the wrong place, i.e. in parameters; mine was dotnet -c Release - o /home/some/path (note the space between - and o), I kept looking at the path itself, which was correct and threw me off. Hope that helps! (this was in Bash though it should also apply to Windows)

try this:

$('div[id^="player_"]')

Place this line before the closing script tag,writing from memory:

window.onload  = GetTimeZoneOffset;

i think the question is how to call the javascript function on pageload

You have several options ;)

$memcache_enabled = class_exists('Memcache');
$memcache_enabled = extension_loaded('memcache');
$memcache_enabled = function_exists('memcache_connect');

Just replace @latest with the version number you want to downgrade to. I wanted to downgrade to version 3.10.10, so I used this command:

npm install -g [email protected]

If you're not sure which version you should use, look at the version history. For example, you can see that 3.10.10 is the latest version of npm 3.

To get the version of JVM currently running the program

System.out.println(Runtime.class.getPackage().getImplementationVersion());

I think the best and cleanest solution you can imagine is this:

@Component( {
  selector: 'app-my-component',
  template: `<p>{{ myData?.anyfield }}</p>`,
  styles: [ '' ]
} )
export class MyComponent implements OnInit {
  private myData;

  constructor( private myService: MyService ) { }

  ngOnInit( ) {
    /* 
      async .. await 
      clears the ExpressionChangedAfterItHasBeenCheckedError exception.
    */
    this.myService.myObservable.subscribe(
      async (data) => { this.myData = await data }
    );
  }
}

Tested with Angular 5.2.9
