Edit the code to be as follows:

// Upload file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "images/" . "myFile.txt" );

if( $moved ) {
  echo "Successfully uploaded";         
} else {
  echo "Not uploaded because of error #".$_FILES["file"]["error"];
}

It will give you one of the following error code values 1 to 8:

UPLOAD_ERR_INI_SIZE = Value: 1; The uploaded file exceeds the upload_max_filesize directive in php.ini.

UPLOAD_ERR_FORM_SIZE = Value: 2; The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.

UPLOAD_ERR_PARTIAL = Value: 3; The uploaded file was only partially uploaded.

UPLOAD_ERR_NO_FILE = Value: 4; No file was uploaded.

UPLOAD_ERR_NO_TMP_DIR = Value: 6; Missing a temporary folder. Introduced in PHP 5.0.3.

UPLOAD_ERR_CANT_WRITE = Value: 7; Failed to write file to disk. Introduced in PHP 5.1.0.

UPLOAD_ERR_EXTENSION = Value: 8; A PHP extension stopped the file upload. PHP does not provide a way to ascertain which extension caused the file upload to stop; examining the list of loaded extensions with phpinfo() may help.

A better way in long run is to integrate Gradle in your project environment. Its a build tool for Java, and now being used a lot in the android development space.

You will need to make a .gradle file and list your library dependencies. Then, all you would need to do is import the project in IntelliJ using Gradle.

If the class does not have toString() method, then you can use ToStringBuilder class from org.apache.commons:commons-lang3

pom.xml:

<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-lang3</artifactId>
  <version>3.10</version>
</dependency>

code:

ToStringBuilder.reflectionToString(yourObject)

For what it's worth I had this issue and had to go into cPanel where I saw the error message

"Attention! Please register your email IDs used in non-smtp mails through cpanel plugin. Unregistered email IDs will not be allowed in non-smtp emails sent through scripts. Go to Mail section and find "Registered Mail IDs" plugin in paper_lantern theme."

Registering the emails in cPanel (Register Mail IDs) and waiting 10 mins got mine to work.

Hope that helps someone.

Behold:

a = [4, 6, 12]
reduce(lambda c, x: c + [c[-1] + x], a, [0])[1:]

Will output (as expected):

[4, 10, 22]

SELECT * FROM pg_stat_activity WHERE datname = 'dbname' and state = 'active';

Since pg_stat_activity contains connection statistics of all databases having any state, either idle or active, database name and connection state should be included in the query to get the desired output.

For those future visitors who may be interested in knowing about those memory segments, I am writing important points about 5 memory segments in C:

Some heads up:

1. Whenever a C program is executed some memory is allocated in the RAM for the program execution. This memory is used for storing the frequently executed code (binary data), program variables, etc. The below memory segments talks about the same:
2. Typically there are three types of variables:
   • Local variables (also called as automatic variables in C)
   • Global variables
   • Static variables
   • You can have global static or local static variables, but the above three are the parent types.

5 Memory Segments in C:

1. Code Segment

• The code segment, also referred as the text segment, is the area of memory which contains the frequently executed code.
• The code segment is often read-only to avoid risk of getting overridden by programming bugs like buffer-overflow, etc.
• The code segment does not contain program variables like local variable (also called as automatic variables in C), global variables, etc.
• Based on the C implementation, the code segment can also contain read-only string literals. For example, when you do printf("Hello, world") then string "Hello, world" gets created in the code/text segment. You can verify this using size command in Linux OS.
• Further reading

Data Segment

The data segment is divided in the below two parts and typically lies below the heap area or in some implementations above the stack, but the data segment never lies between the heap and stack area.

2. Uninitialized data segment

• This segment is also known as bss.
• This is the portion of memory which contains:
  1. Uninitialized global variables (including pointer variables)
  2. Uninitialized constant global variables.
  3. Uninitialized local static variables.
• Any global or static local variable which is not initialized will be stored in the uninitialized data segment
• For example: global variable int globalVar; or static local variable static int localStatic; will be stored in the uninitialized data segment.
• If you declare a global variable and initialize it as 0 or NULL then still it would go to uninitialized data segment or bss.
• Further reading

3. Initialized data segment

• This segment stores:
  1. Initialized global variables (including pointer variables)
  2. Initialized constant global variables.
  3. Initialized local static variables.
• For example: global variable int globalVar = 1; or static local variable static int localStatic = 1; will be stored in initialized data segment.
• This segment can be further classified into initialized read-only area and initialized read-write area. Initialized constant global variables will go in the initialized read-only area while variables whose values can be modified at runtime will go in the initialized read-write area.
• The size of this segment is determined by the size of the values in the program's source code, and does not change at run time.
• Further reading

4. Stack Segment

• Stack segment is used to store variables which are created inside functions (function could be main function or user-defined function), variable like
  1. Local variables of the function (including pointer variables)
  2. Arguments passed to function
  3. Return address
• Variables stored in the stack will be removed as soon as the function execution finishes.
• Further reading

5. Heap Segment

• This segment is to support dynamic memory allocation. If the programmer wants to allocate some memory dynamically then in C it is done using the malloc, calloc, or realloc methods.
• For example, when int* prt = malloc(sizeof(int) * 2) then eight bytes will be allocated in heap and memory address of that location will be returned and stored in ptr variable. The ptr variable will be on either the stack or data segment depending on the way it is declared/used.

See details in the below image. (VSCode version 1.19.1 - windows 10 OS)

It works on VS Code Mac as well. I tried it with VSCode (Version 1.20.1)

The easiest way is to use the library commands

import commands
print commands.getstatusoutput('echo "test" | wc')

It's preferable to use context managers to close the files automatically

with open("new.txt", "r"), open('xyz.txt', 'w') as textfile, myfile:
    for line in textfile:
        var1, var2 = line.split(",");
        myfile.writelines(var1)

There are many ways to achieve this but the easiest way in Python 3.6+, in my opinion, is this:

print(f"{1:03}")

You need to disable Script Debugging In Visual Studio

Instead of storing the output of grep in a variable and then checking whether the variable is empty, you can do this:

if grep -q "poet" $file_name
then
    echo "poet was found in $file_name"
fi

============

Here are some commonly used tests:

   -d FILE
          FILE exists and is a directory
   -e FILE
          FILE exists
   -f FILE
          FILE exists and is a regular file
   -h FILE
          FILE exists and is a symbolic link (same as -L)
   -r FILE
          FILE exists and is readable
   -s FILE
          FILE exists and has a size greater than zero
   -w FILE
          FILE exists and is writable
   -x FILE
          FILE exists and is executable
   -z STRING
          the length of STRING is zero

Example:

if [ -e "$file_name" ] && [ ! -z "$used_var" ]
then
    echo "$file_name exists and $used_var is not empty"
fi

Have you tried Hammerjs? It supports swipe gestures by using the velocity of the touch. http://eightmedia.github.com/hammer.js/

For project dependencies use:

npm list --depth=0

For global dependencies use:

npm list -g --depth=0

There is many ways to do that but one of them is fiddler

Fiddler Configuration

1. Go to options
2. In HTTPS tab, enable Capture HTTPS Connects and Decrypt HTTPS traffic
3. In Connections tab, enable Allow remote computers to connect
4. Restart fiddler

Android Configuration

1. Connect to same network
2. Modify network settings
3. Add proxy for connection with your PC's IP address ( or hostname ) and default fiddler's port ( 8888 / you can change that in settings )

Now you can see full log from your device in fiddler

Also you can find a full instruction here

[EditorBrowsable(EditorBrowsableState.Never)] allows you to hide properties and methods from IntelliSense if the project is not in your solution. Very helpful for hiding invalid flows for fluent interfaces. How often do you want to GetHashCode() or Equals()?

For MVC [ActionName("Name")] allows you to have a Get action and Post action with the same method signature, or to use dashes in the action name, which otherwise would not be possible without creating a route for it.

Length of characters to be matched.

{n,m}  n <= length <= m
{n}    length == n
{n,}   length >= n

And by default, the engine is greedy to match this pattern. For example, if the input is 123456789, \d{2,5} will match 12345 which is with length 5.

If you want the engine returns when length of 2 matched, use \d{2,5}?

Have a look at GROUP_CONCAT if your MySQL version (4.1) supports it. See the documentation for more details.

It would look something like:

  SELECT GROUP_CONCAT(hobbies SEPARATOR ', ') 
  FROM peoples_hobbies 
  WHERE person_id = 5 
  GROUP BY 'all';

If you want to avoid collisions you may want to use a secure hash like SHA-256. There are several JavaScript SHA-256 implementations.

I wrote tests to compare several hash implementations, see https://github.com/brillout/test-javascript-hash-implementations.

Or go to http://brillout.github.io/test-javascript-hash-implementations/, to run the tests.

To start Jupyter Notebook in Windows:

• open a Windows cmd (win + R and return cmd)
• change directory to the desired file path (cd file-path)
• give command jupyter notebook

You can further navigate from the UI of Jupyter notebook after you launch it (if you are not directly launching the right file.)
OR you can directly drag and drop the file to the cmd, to open the file.

Multiple pdf merged method using org.apache.pdfbox:

public void mergePDFFiles(List<File> files,
                          String mergedFileName) {
    try {
        PDFMergerUtility pdfmerger = new PDFMergerUtility();
        for (File file : files) {
            PDDocument document = PDDocument.load(file);
            pdfmerger.setDestinationFileName(mergedFileName);
            pdfmerger.addSource(file);
            pdfmerger.mergeDocuments(MemoryUsageSetting.setupTempFileOnly());
            document.close();
        }
    } catch (IOException e) {
        logger.error("Error to merge files. Error: " + e.getMessage());
    }
}

From main program, call mergePDFFiles method using list of files and target file name.

        String mergedFileName = "Merged.pdf";
        mergePDFFiles(files, mergedFileName);

After calling mergePDFFiles, load merged file

        File mergedFile = new File(mergedFileName);

I resolved it by selecting http as the protocol and giving my GitHub username and password.

In order to handle arrays with the $resource service, it's suggested that you use the query method. As you can see below, the query method is built to handle arrays.

    { 'get':    {method:'GET'},
      'save':   {method:'POST'},
      'query':  {method:'GET', isArray:true},
      'remove': {method:'DELETE'},
      'delete': {method:'DELETE'} 
   };

User $resource("apiUrl").query();

Which model is the "best fitting model" depends on what you mean by "best". R has tools to help, but you need to provide the definition for "best" to choose between them. Consider the following example data and code:

x <- 1:10
y <- x + c(-0.5,0.5)

plot(x,y, xlim=c(0,11), ylim=c(-1,12))

fit1 <- lm( y~offset(x) -1 )
fit2 <- lm( y~x )
fit3 <- lm( y~poly(x,3) )
fit4 <- lm( y~poly(x,9) )
library(splines)
fit5 <- lm( y~ns(x, 3) )
fit6 <- lm( y~ns(x, 9) )

fit7 <- lm( y ~ x + cos(x*pi) )

xx <- seq(0,11, length.out=250)
lines(xx, predict(fit1, data.frame(x=xx)), col='blue')
lines(xx, predict(fit2, data.frame(x=xx)), col='green')
lines(xx, predict(fit3, data.frame(x=xx)), col='red')
lines(xx, predict(fit4, data.frame(x=xx)), col='purple')
lines(xx, predict(fit5, data.frame(x=xx)), col='orange')
lines(xx, predict(fit6, data.frame(x=xx)), col='grey')
lines(xx, predict(fit7, data.frame(x=xx)), col='black')

Which of those models is the best? arguments could be made for any of them (but I for one would not want to use the purple one for interpolation).

Below is an example:

Please see this for more reference of type comparisons in PHP. It should give you a clear understanding.

Not only you can add a path, but you can add git diff --relative to get result relative to that folder.

git -C a/folder diff --relative

And with Git 2.28 (Q3 2020), the commands in the "diff" family learned to honor the "diff.relative" configuration variable.

See commit c28ded8 (22 May 2020) by Laurent Arnoud (spk).
^{(Merged by Junio C Hamano -- gitster -- in commit e34df9a, 02 Jun 2020)}

diff: add config option relative

^{Signed-off-by: Laurent Arnoud
Acked-by: Ðoàn Tr?n Công Danh}

The diff.relative boolean option set to true shows only changes in the current directory/value specified by the path argument of the relative option and shows pathnames relative to the aforementioned directory.

Teach --no-relative to override earlier --relative

Add for git-format-patch(1) options documentation --relative and --no-relative

The documentation now includes:

diff.relative:

If set to 'true', 'git diff' does not show changes outside of the directory and show pathnames relative to the current directory.

SOAPpy is now obsolete, AFAIK, replaced by ZSL. It's a moot point, because I can't get either one to work, much less compile, on either Python 2.5 or Python 2.6

This an old question but for people still looking. In JS you can now use the title property.

button.title = ("Popup text here");

A pixel is the smallest unit value to render something with, but you can trick thickness with optical illusions by modifying colors (the eye can only see up to a certain resolution too).

Here is a test to prove this point:

div { border-color: blue; border-style: solid; margin: 2px; }

div.b1 { border-width: 1px; }
div.b2 { border-width: 0.1em; }
div.b3 { border-width: 0.01em; }
div.b4 { border-width: 1px; border-color: rgb(160,160,255); }

<div class="b1">Some text</div>
<div class="b2">Some text</div>
<div class="b3">Some text</div>
<div class="b4">Some text</div>

Output

Which gives the illusion that the last DIV has a smaller border width, because the blue border blends more with the white background.

Edit: Alternate solution

Alpha values may also be used to simulate the same effect, without the need to calculate and manipulate RGB values.

.container {
  border-style: solid;
  border-width: 1px;
  
  margin-bottom: 10px;
}

.border-100 { border-color: rgba(0,0,255,1); }
.border-75 { border-color: rgba(0,0,255,0.75); }
.border-50 { border-color: rgba(0,0,255,0.5); }
.border-25 { border-color: rgba(0,0,255,0.25); }

<div class="container border-100">Container 1 (alpha = 1)</div>
<div class="container border-75">Container 2 (alpha = 0.75)</div>
<div class="container border-50">Container 3 (alpha = 0.5)</div>
<div class="container border-25">Container 4 (alpha = 0.25)</div>

Scripting is inevitable.

This isn't provided because of the security risk. <input type='file' /> is closest, but not what you are looking for.

Checkout this example that uses Javascript to achieve what you want.

If the OS is windows, you can use VB scripts to access the core control files to browse for a folder.

Edit: Please read comments. It turns out this only works well in V8 (Chrome / Node.JS) My intent was to provide a cross-browser solution, which would work in all browsers, and provide stack trace where support is there.

Edit: I made this Community Wiki to allow for more editing.

Solution for V8 (Chrome / Node.JS), works in Firefox, and can be modified to function mostly correctly in IE. (see end of post)

function UserError(message) {
  this.constructor.prototype.__proto__ = Error.prototype // Make this an instanceof Error.
  Error.call(this) // Does not seem necessary. Perhaps remove this line?
  Error.captureStackTrace(this, this.constructor) // Creates the this.stack getter
  this.name = this.constructor.name; // Used to cause messages like "UserError: message" instead of the default "Error: message"
  this.message = message; // Used to set the message
}

Original post on "Show me the code !"

Short version:

function UserError(message) {
  this.constructor.prototype.__proto__ = Error.prototype
  Error.captureStackTrace(this, this.constructor)
  this.name = this.constructor.name
  this.message = message
}

I keep this.constructor.prototype.__proto__ = Error.prototype inside the function to keep all the code together. But you can also replace this.constructor with UserError and that allows you to move the code to outside the function, so it only gets called once.

If you go that route, make sure you call that line before the first time you throw UserError.

That caveat does not apply the function, because functions are created first, no matter the order. Thus, you can move the function to the end of the file, without a problem.

Browser Compatibility

Works in Firefox and Chrome (and Node.JS) and fills all promises.

Internet Explorer fails in the following

• Errors do not have err.stack to begin with, so "it's not my fault".

• Error.captureStackTrace(this, this.constructor) does not exist so you need to do something else like

  if(Error.captureStackTrace) // AKA if not IE
      Error.captureStackTrace(this, this.constructor)
  

• toString ceases to exist when you subclass Error. So you also need to add.

  else
      this.toString = function () { return this.name + ': ' + this.message }
  

• IE will not consider UserError to be an instanceof Error unless you run the following some time before you throw UserError

  UserError.prototype = Error.prototype
  

You can create a custom directive that is somehow similar to ng-disabled and disable a specific set of elements by:

1. watching the property changes of the custom directive, e.g. my-disabled.
2. clone the current element without the added event handlers.
3. add css properties to the cloned element and other attributes or event handlers that will provide the disabled state of an element.
4. when changes are detected on the watched property, replace the current element with the cloned element.

HTML

   <a my-disabled="disableCreate" href="#" ng-click="disableEdit = true">CREATE</a><br/>
   <a my-disabled="disableEdit" href="#" ng-click="disableCreate = true">EDIT</a><br/>
   <a my-disabled="disableCreate || disableEdit" href="#">DELETE</a><br/>
   <a href="#" ng-click="disableEdit = false; disableCreate = false;">RESET</a>

JAVASCRIPT

directive('myDisabled', function() {
  return {

    link: function(scope, elem, attr) {
      var color = elem.css('color'),
          textDecoration = elem.css('text-decoration'),
          cursor = elem.css('cursor'),
          // double negation for non-boolean attributes e.g. undefined
          currentValue = !!scope.$eval(attr.myDisabled),

          current = elem[0],
          next = elem[0].cloneNode(true);

      var nextElem = angular.element(next);

      nextElem.on('click', function(e) {
        e.preventDefault();
        e.stopPropagation();
      });

      nextElem.css('color', 'gray');
      nextElem.css('text-decoration', 'line-through');
      nextElem.css('cursor', 'not-allowed');
      nextElem.attr('tabindex', -1);

      scope.$watch(attr.myDisabled, function(value) {
        // double negation for non-boolean attributes e.g. undefined
        value = !!value;

        if(currentValue != value) {
          currentValue = value;
          current.parentNode.replaceChild(next, current);
          var temp = current;
          current = next;
          next = temp;
        }

      })
    }
  }
});

To pass a pointer to an int it should be void Fun(int* pointer).

Passing a reference to an int would look like this...

void Fun(int& ref) {
   ref = 10;
}

int main() {
   int test = 5;
   cout << test << endl;  // prints 5

   Fun(test);
   cout << test << endl;  // prints 10 because Fun modified the value

   return 1;
}

You can generate statement like this: DROP TABLE t1, t2, t3, ... and then use prepared statements to execute it:

SET FOREIGN_KEY_CHECKS = 0; 
SET @tables = NULL;
SELECT GROUP_CONCAT('`', table_schema, '`.`', table_name, '`') INTO @tables
  FROM information_schema.tables 
  WHERE table_schema = 'database_name'; -- specify DB name here.

SET @tables = CONCAT('DROP TABLE ', @tables);
PREPARE stmt FROM @tables;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1;

You can open the file using the ios::ate flag (and ios::binary flag), so the tellg() function will give you directly the file size:

ifstream file( "example.txt", ios::binary | ios::ate);
return file.tellg();

Insert this in your Makefile

 $(MAKE) -C $(KDIR) M=$(PWD) modules_install                      

 it will install the module in the directory /lib/modules/<var>/extra/
 After make , insert module with modprobe module_name (without .ko extension)

OR

After your normal make, you copy module module_name.ko into   directory  /lib/modules/<var>/extra/

then do modprobe module_name (without .ko extension)

Actually, you should use the translate directive for such stuff instead.

<h1 translate="{{pageTitle}}"></h1>

The directive takes care of asynchronous execution and is also clever enough to unwatch translation ids on the scope if the translation has no dynamic values.

However, if there's no way around and you really have to use $translate service in the controller, you should wrap the call in a $translateChangeSuccess event using $rootScope in combination with $translate.instant() like this:

.controller('foo', function ($rootScope, $scope, $translate) {
  $rootScope.$on('$translateChangeSuccess', function () {
    $scope.pageTitle = $translate.instant('PAGE.TITLE');
  });
})

So why $rootScope and not $scope? The reason for that is, that in angular-translate's events are $emited on $rootScope rather than $broadcasted on $scope because we don't need to broadcast through the entire scope hierarchy.

Why $translate.instant() and not just async $translate()? When $translateChangeSuccess event is fired, it is sure that the needed translation data is there and no asynchronous execution is happening (for example asynchronous loader execution), therefore we can just use $translate.instant() which is synchronous and just assumes that translations are available.

Since version 2.8.0 there is also $translate.onReady(), which returns a promise that is resolved as soon as translations are ready. See the changelog.

One problem with StringWriter is that by default it doesn't let you set the encoding which it advertises - so you can end up with an XML document advertising its encoding as UTF-16, which means you need to encode it as UTF-16 if you write it to a file. I have a small class to help with that though:

public sealed class StringWriterWithEncoding : StringWriter
{
    public override Encoding Encoding { get; }

    public StringWriterWithEncoding (Encoding encoding)
    {
        Encoding = encoding;
    }    
}

Or if you only need UTF-8 (which is all I often need):

public sealed class Utf8StringWriter : StringWriter
{
    public override Encoding Encoding => Encoding.UTF8;
}

As for why you couldn't save your XML to the database - you'll have to give us more details about what happened when you tried, if you want us to be able to diagnose/fix it.

I think that what you have to do is make a thorough check of some properties that will always be in a dom element, but their combination won't most likely be in another object, like so:

var isDom = function (inp) {
    return inp && inp.tagName && inp.nodeName && inp.ownerDocument && inp.removeAttribute;
};

You need to declare the array in the HTML via

<input type="checkbox" name="Days[]" value="Daily">

Also you can insert multiple items with one query like this

$query = "INSERT INTO example (orange) VALUES ";
for ($i=0; $i<count($checkBox); $i++)
    $query .= "('" . $checkBox[$i] . "'),";
$query = rtrim($query,',');
mysql_query($query) or die (mysql_error() );

Also keep in mind that mysql_* functions are officially deprecated and hence should not be used in new code. You can use PDO or MySQLi instead. See this answer on SO for more information.

This bug cost me 2 days. I checked my Server log, the Preflight Option request/response between browser Chrome/Edge and Server was ok. The main reason is that GET/POST/PUT/DELETE server response for XHTMLRequest must also have the following header:

access-control-allow-origin: origin  

"origin" is in the request header (Browser will add it to request for you). for example:

Origin: http://localhost:4221

you can add response header like the following to accept for all:

access-control-allow-origin: *  

or response header for a specific request like:

access-control-allow-origin: http://localhost:4221 

The message in browsers is not clear to understand: "...The requested resource"

note that: CORS works well for localhost. different port means different Domain. if you get error message, check the CORS config on the server side.

Your function declares a constant reference to a string:

int foo(const string &myname) {
  cout << "called foo for: " << myname << endl;
  return 0;
}

A reference has some special properties, which make it a safer alternative to pointers in many ways:

• it can never be NULL
• it must always be initialised
• it cannot be changed to refer to a different variable once set
• it can be used in exactly the same way as the variable to which it refers (which means you do not need to deference it like a pointer)

How does the function signature differ from the equivalent C:

int foo(const char *myname)

There are several differences, since the first refers directly to an object, while const char* must be dereferenced to point to the data.

Is there a difference between using string *myname vs string &myname?

The main difference when dealing with parameters is that you do not need to dereference &myname. A simpler example is:

int add_ptr(int *x, int* y)
{
    return *x + *y;
}
int add_ref(int &x, int &y)
{
    return x + y;
}

which do exactly the same thing. The only difference in this case is that you do not need to dereference x and y as they refer directly to the variables passed in.

const string &GetMethodName() { ... }

What is the & doing here? Is there some website that explains how & is used differently in C vs C++?

This returns a constant reference to a string. So the caller gets to access the returned variable directly, but only in a read-only sense. This is sometimes used to return string data members without allocating extra memory.

There are some subtleties with references - have a look at the C++ FAQ on References for some more details.

The way I got around this issue is by not calling intent within a dialog. **** use syntax applicable to activity or fragment accordingly

@Override
public void onClick(DialogInterface dialog, int which) {
    checkvariable= true;
    getActivity().finish();
}

@Override
public void onStop() {
    super.onStop();
    if (checkvariable) {
        startActivity(intent); 
    }
}

default value is chosen at runtime based on system configuration

Have a look at the documentation page

Default Heap Size

Unless the initial and maximum heap sizes are specified on the command line, they are calculated based on the amount of memory on the machine.

1. Client JVM Default Initial and Maximum Heap Sizes:

   The default maximum heap size is half of the physical memory up to a physical memory size of 192 megabytes (MB) and otherwise one fourth of the physical memory up to a physical memory size of 1 gigabyte (GB).

2. Server JVM Default Initial and Maximum Heap Sizes:

   On 32-bit JVMs, the default maximum heap size can be up to 1 GB if there is 4 GB or more of physical memory. On 64-bit JVMs, the default maximum heap size can be up to 32 GB if there is 128 GB or more of physical memory

What system configuration settings influence the default value?

You can specify the initial and maximum heap sizes using the flags -Xms (initial heap size) and -Xmx (maximum heap size). If you know how much heap your application needs to work well, you can set -Xms and -Xmx to the same value

The problem is that you forgot to import os. Add this line of code:

import os

And everything should be fine. Hope this helps!

If your table is separated by others than tabs, you should specify it like...

LOAD DATA LOCAL 
    INFILE '/tmp/mydata.txt' INTO TABLE PerformanceReport 
    COLUMNS TERMINATED BY '\t'  ## This should be your delimiter
    OPTIONALLY ENCLOSED BY '"'; ## ...and if text is enclosed, specify here

1. Register your website at – https://www.google.com/recaptcha/admin
2. add js plugin 3.add class and your site-key provived by google

 <div class="g-recaptcha" data-sitekey="your site-key"></div>

subprocess.Popen takes a cwd argument to set the Current Working Directory; you'll also want to escape your backslashes ('d:\\test\\local'), or use r'd:\test\local' so that the backslashes aren't interpreted as escape sequences by Python. The way you have it written, the \t part will be translated to a tab.

So, your new line should look like:

subprocess.Popen(r'c:\mytool\tool.exe', cwd=r'd:\test\local')

To use your Python script path as cwd, import os and define cwd using this:

os.path.dirname(os.path.realpath(__file__)) 

This is are other ways of printing empty lines in python

# using \n after the string creates an empty line after this string is passed to the the terminal.
print("We need to put about", average_passengers_per_car, "in each car. \n") 
print("\n") #prints 2 empty lines 
print() #prints 1 empty line 

Use this:

String str = " 12,12"
str = str.replaceAll("(\\d+)\\,(\\d+)", "$1.$2");
System.out.println("str:"+str); //-> str:12.12

hope help you.

Even if it is really discouraged to use merge cells in Excel (use Center Across Selection for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).

Hence, you can get the value of merged cells in range B4:B11 in several ways:

• Range("B4").Value
• Range("B4:B11").Cells(1).Value
• Range("B4:B11").Cells(1,1).Value

You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty.

Also note that Range("B4:B11").Value won't work (raises an execution error number 13 if you try to Debug.Print it) because it returns an array.

The upvoted solution works for some situations but is not the ideal solution. The solution Bhojendra Rauniyar provided will only work in certain scenarios. The var inputVal will always remain the same, so changing the input multiple times would break the function.

The function may also break when using focus, because of the ?? (up/down) spinner on html number input. That is why J.T. Taylor has the best solution. By adding a data attribute you can avoid these problems:

<input id="my-textbox" type="text" data-initial-value="6" value="6" />

Change . to / as the path separator and use getResourceAsStream:

reader = new BufferedReader(new InputStreamReader(
    getClass().getClassLoader().getResourceAsStream(
        "com/company/app/dao/sql/SqlQueryFile.sql")));

or

reader = new BufferedReader(new InputStreamReader(
    getClass().getResourceAsStream(
        "/com/company/app/dao/sql/SqlQueryFile.sql")));

Note the leading slash when using Class.getResourceAsStream() vs ClassLoader.getResourceAsStream. getSystemResourceAsStream uses the system classloader which isn't what you want.

I suspect that using slashes instead of dots would work for ClassPathResource too.

for python 3.8 version go for anaconda navigator then go for environments --> then go for base(root)----> not installed from drop box--->then search for tensorflow then install it then run the program.......hope it may helpful

var dd = document.getElementById("dropdownID");
var selectedItem = dd.options[dd.selectedIndex].value;

Here is what you can do using jquery:

$('#A_ID').click(function (e) { //#A_ID is an example. Use the id of your Anchor
    $('html, body').animate({
        scrollTop: $('#DIV_ID').offset().top - 20 //#DIV_ID is an example. Use the id of your destination on the page
    }, 'slow');
});

You can index into a string in C# like an array, and you get the character at that index.

Example:

In Java, you would say

str.charAt(8);

In C#, you would say

str[8];

Not sure if this is a feature or a bug but this worked for us:

git commit '' -m "Message"

Note the empty file list ''. Git interprets this to commit all modified tracked files, even if they are not staged, and ignore untracked files.

Hello Try this code below

public class RemoveCharacter {

        System.out.println(removeChr(str,x));
    }

    public static String removeChr(String str, char x){

        char[] rmString = str.toCharArray();
        for(int i=0; i<rmString.length; i++){

SQL Server 2008+ has a "time" datatype

SELECT 
    ..., CAST(MyDateTimeCol AS time)
FROM
   ...

For older versions, without varchar conversions

SELECT 
    ..., DATEADD(dd, DATEDIFF(dd, MyDateTimeCol, 0), MyDateTimeCol)
FROM
   ...

In z/OS while on version 10, use of CURRENT APPLICATION COMPATIBILITY is not allowed. You will have to resort to:

SELECT GETVARIABLE('SYSIBM.VERSION') AS VERSION,
       GETVARIABLE('SYSIBM.NEWFUN')  AS COMPATIBILITY
FROM SYSIBM.SYSDUMMY1;

I'm guessing that either the class name is wrong - be sure to use the fully-resolved class name, with all packages - or it's not in the CLASSPATH so javap can't find it.

In mysql definitions (manual) there is no such thing. But if you have a really big number of columns col1, ..., col100, the following can be useful:

DROP TABLE IF EXISTS temp_tb;
CREATE TEMPORARY TABLE ENGINE=MEMORY temp_tb SELECT * FROM orig_tb;
ALTER TABLE temp_tb DROP col_x;
   #// ALTER TABLE temp_tb DROP col_a, ... , DROP col_z; #// for a few columns to drop
SELECT * FROM temp_tb;

<input type="text" placeholder="specify">

This adds "specify" as tool-tip text inside the input box.

Using app:showAsAction="always|withText". I am using Android 4.1.1, but it should applicable anyway. Mine look like below

        android:orderInCategory="100"

useState() is a React hook. Hooks make possible to use state and mutability inside function components.

While you can't use hooks inside classes you can wrap your class component with a function one and use hooks from it. This is a great tool for migrating components from class to function form. Here is a complete example:

For this example I will use a counter component. This is it:

class Hello extends React.Component {_x000D_
  constructor(props) {_x000D_
    super(props);_x000D_
    this.state = { count: props.count };_x000D_
  }_x000D_
  _x000D_
  inc() {_x000D_
    this.setState(prev => ({count: prev.count+1}));_x000D_
  }_x000D_
  _x000D_
  render() {_x000D_
    return <button onClick={() => this.inc()}>{this.state.count}</button>_x000D_
  }_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Hello count={0}/>, document.getElementById('root'))

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>_x000D_
<div id='root'></div>

It is a simple class component with a count state, and state update is done by methods. This is very common pattern in class components. The first thing is to wrap it with a function component with just the same name, that delegate all its properties to the wrapped component. Also you need to render the wrapped component in the function return. Here it is:

function Hello(props) {_x000D_
  class Hello extends React.Component {_x000D_
    constructor(props) {_x000D_
      super(props);_x000D_
      this.state = { count: props.count };_x000D_
    }_x000D_
_x000D_
    inc() {_x000D_
      this.setState(prev => ({count: prev.count+1}));_x000D_
    }_x000D_
_x000D_
    render() {_x000D_
      return <button onClick={() => this.inc()}>{this.state.count}</button>_x000D_
    }_x000D_
  }_x000D_
  return <Hello {...props}/>_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Hello count={0}/>, document.getElementById('root'))

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>_x000D_
<div id='root'></div>

This is exactly the same component, with the same behavior, same name and same properties. Now lets lift the counting state to the function component. This is how it goes:

function Hello(props) {_x000D_
  const [count, setCount] = React.useState(0);_x000D_
  class Hello extends React.Component {_x000D_
    constructor(props) {_x000D_
      super(props);_x000D_
      this.state = { count: props.count };_x000D_
    }_x000D_
_x000D_
    inc() {_x000D_
      this.setState(prev => ({count: prev.count+1}));_x000D_
    }_x000D_
_x000D_
    render() {_x000D_
      return <button onClick={() => setCount(count+1)}>{count}</button>_x000D_
    }_x000D_
  }_x000D_
  return <Hello {...props}/>_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Hello count={0}/>, document.getElementById('root'))

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.8.6/umd/react.production.min.js" integrity="sha256-3vo65ZXn5pfsCfGM5H55X+SmwJHBlyNHPwRmWAPgJnM=" crossorigin="anonymous"></script>_x000D_

<div id='root'></div>

Note that the method inc is still there, it wont hurt anybody, in fact is dead code. This is the idea, just keep lifting state up. Once you finished you can remove the class component:

function Hello(props) {_x000D_
  const [count, setCount] = React.useState(0);_x000D_
_x000D_
  return <button onClick={() => setCount(count+1)}>{count}</button>;_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Hello count={0}/>, document.getElementById('root'))

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.8.6/umd/react.production.min.js" integrity="sha256-3vo65ZXn5pfsCfGM5H55X+SmwJHBlyNHPwRmWAPgJnM=" crossorigin="anonymous"></script>_x000D_

_x000D_
<div id='root'></div>

While this makes possible to use hooks inside class components, I would not recommend you to do so except if you migrating like I did in this example. Mixing function and class components will make state management a mess. I hope this helps

Best Regards

Just like any other simple command, [ ... ] or test requires spaces between its arguments.

if [ "$#" -ne 1 ]; then
    echo "Illegal number of parameters"
fi

Or

if test "$#" -ne 1; then
    echo "Illegal number of parameters"
fi

Suggestions

When in Bash, prefer using [[ ]] instead as it doesn't do word splitting and pathname expansion to its variables that quoting may not be necessary unless it's part of an expression.

[[ $# -ne 1 ]]

It also has some other features like unquoted condition grouping, pattern matching (extended pattern matching with extglob) and regex matching.

The following example checks if arguments are valid. It allows a single argument or two.

[[ ($# -eq 1 || ($# -eq 2 && $2 == <glob pattern>)) && $1 =~ <regex pattern> ]]

For pure arithmetic expressions, using (( )) to some may still be better, but they are still possible in [[ ]] with its arithmetic operators like -eq, -ne, -lt, -le, -gt, or -ge by placing the expression as a single string argument:

A=1
[[ 'A + 1' -eq 2 ]] && echo true  ## Prints true.

That should be helpful if you would need to combine it with other features of [[ ]] as well.

Take note that [[ ]] and (( )) are keywords which have same level of parsing as if, case, while, and for.

Also as Dave suggested, error messages are better sent to stderr so they don't get included when stdout is redirected:

echo "Illegal number of parameters" >&2

Exiting the script

It's also logical to make the script exit when invalid parameters are passed to it. This has already been suggested in the comments by ekangas but someone edited this answer to have it with -1 as the returned value, so I might as well do it right.

-1 though accepted by Bash as an argument to exit is not explicitly documented and is not right to be used as a common suggestion. 64 is also the most formal value since it's defined in sysexits.h with #define EX_USAGE 64 /* command line usage error */. Most tools like ls also return 2 on invalid arguments. I also used to return 2 in my scripts but lately I no longer really cared, and simply used 1 in all errors. But let's just place 2 here since it's most common and probably not OS-specific.

if [[ $# -ne 1 ]]; then
    echo "Illegal number of parameters"
    exit 2
fi

You can stop the 2-line separation in the output by using

    with open('t.ini') as f:
       for line in f:
           print line.strip()
           if 'str' in line:

Did have identical problem with on XP machine when installing javacv and opencv in combination with Eclipse. It turned out that I was missing the following files:

• msvcp100.dll
• msvcr100.dll

Once these were installed, the project compiled and ran OK.

You can use opendir and readdir to read directory entries and unlink to delete them.

Pushing and popping registers are behind the scenes equivalent to this:

push reg   <= same as =>      sub  $8,%rsp        # subtract 8 from rsp
                              mov  reg,(%rsp)     # store, using rsp as the address

pop  reg    <= same as=>      mov  (%rsp),reg     # load, using rsp as the address
                              add  $8,%rsp        # add 8 to the rsp

Note this is x86-64 At&t syntax.

Used as a pair, this lets you save a register on the stack and restore it later. There are other uses, too.

When I were trying install librosa package with pip (pip install librosa), this error were appeared:

I tried to remove llvmlite, but pip uninstall could not remove it. So, I used capability of ignore of pip by this code:

pip install librosa --ignore-installed llvmlite

Indeed, you can use this rule for ignoring a package you don't want to consider:

pip install {package you want to install} --ignore-installed {installed package you don't want to consider}

the connection url for postgres syntax:

"Server=host ipaddress;Port=5432;Database=dbname;User Id=userid;Password=password;

example:

"Server=192.168.1.163;Port=5432;Database=postgres;User Id=postgres;Password=root;

If you want to just accept defaults you can use:

\n | ./shell_being_run

If you want it to be more generic and independent, you can use cookie. Iframe content can set a cookie. With jquery.cookie and a timer (or in this case javascript timer), you can check if the cookie is set each second or so.

//token should be a unique random value which is also sent to ifame to get set
iframeLoadCheckTimer = window.setInterval(function () {
        cookieValue = $.cookie('iframeToken');  
        if (cookieValue == token)
        {
            window.clearInterval(iframeLoadCheckTimer );
            $.cookie('iframeToken', null, {
                expires: 1, 
                path: '/'
         });
        }
 }, 1000);

For beyond compare on Windows 7

git config --global merge.tool bc3
git config --global mergetool.bc3.path "C:\Program Files (x86)\Beyond Compare 3\BCompare.exe"

I have a lib what use https://requests.readthedocs.io/en/master/ what use https://pypi.org/project/certifi/ but I have a custom CA included in my /etc/ssl/certs.

So I solved my problem like this:

# Your TLS certificates directory (Debian like)
export SSL_CERT_DIR=/etc/ssl/certs
# CA bundle PATH (Debian like again)
export CA_BUNDLE_PATH="${SSL_CERT_DIR}/ca-certificates.crt"
# If you have a virtualenv:
. ./.venv/bin/activate
# Get the current certifi CA bundle
CERTFI_PATH=`python -c 'import certifi; print(certifi.where())'`

test -L $CERTFI_PATH || rm $CERTFI_PATH
test -L $CERTFI_PATH || ln -s $CA_BUNDLE_PATH $CERTFI_PATH

Et voilà !

Using the FM format model modifier to get close, as you won't get the trailing zeros after the decimal separator; but you will still get the separator itself, e.g. 50.. You can use rtrim to get rid of that:

select to_char(a, '99D90'),
    to_char(a, '90D90'),
    to_char(a, 'FM90D99'),
    rtrim(to_char(a, 'FM90D99'), to_char(0, 'D'))
from (
    select 50 a from dual
    union all select 50.57 from dual
    union all select 5.57 from dual
    union all select 0.35 from dual
    union all select 0.4 from dual
)
order by a;

TO_CHA TO_CHA TO_CHA RTRIM(
------ ------ ------ ------
   .35   0.35 0.35   0.35
   .40   0.40 0.4    0.4
  5.57   5.57 5.57   5.57
 50.00  50.00 50.    50
 50.57  50.57 50.57  50.57

Note that I'm using to_char(0, 'D') to generate the character to trim, to match the decimal separator - so it looks for the same character, , or ., as the first to_char adds.

The slight downside is that you lose the alignment. If this is being used elsewhere it might not matter, but it does then you can also wrap it in an lpad, which starts to make it look a bit complicated:

...
lpad(rtrim(to_char(a, 'FM90D99'), to_char(0, 'D')), 6)
...

TO_CHA TO_CHA TO_CHA RTRIM( LPAD(RTRIM(TO_CHAR(A,'FM
------ ------ ------ ------ ------------------------
   .35   0.35 0.35   0.35     0.35
   .40   0.40 0.4    0.4       0.4
  5.57   5.57 5.57   5.57     5.57
 50.00  50.00 50.    50         50
 50.57  50.57 50.57  50.57   50.57

This code takes number of row and column from user then takes elements and displays as a matrix.

m = int(input('number of rows, m : '))
n = int(input('number of columns, n : '))
a=[]
for i in range(1,m+1):
  b = []
  print("{0} Row".format(i))
  for j in range(1,n+1):
    b.append(int(input("{0} Column: " .format(j))))
  a.append(b)
print(a)

Dim fileEntries As String() = Directory.GetFiles("YourPath", "*.txt")
' Process the list of .txt files found in the directory. '
Dim fileName As String

For Each fileName In fileEntries
    If (System.IO.File.Exists(fileName)) Then
        'Read File and Print Result if its true
        ReadFile(fileName)
    End If
    TransfereFile(fileName, 1)
Next

Combining both answers from

Flo & rptwsthi and roetzi,

Do remember to change your layout_width=0dp/px, else the layout_weight behaviour will act reversely with biggest number occupied the smallest space and lowest number occupied the biggest space.

Besides, some weights combination will caused some layout cannot be shown (since it over occupied the space).

Beware of this.

I had the same issue using an older version of Fancybox. Upgrading to v3 will solve your problem OR you can just add:

html, body {
    -webkit-overflow-scrolling : touch !important;
    overflow: auto !important;
    height: 100% !important;
}

This worked just fine for me:

requestDispatcher - forward() method

1. When we use the forward method, the request is transferred to another resource within the same server for further processing.

2. In the case of forward, the web container handles all processing internally and the client or browser is not involved.

3. When forward is called on the requestDispatcherobject, we pass the request and response objects, so our old request object is present on the new resource which is going to process our request.

4. Visually, we are not able to see the forwarded address, it is transparent.

5. Using the forward() method is faster than sendRedirect.

6. When we redirect using forward, and we want to use the same data in a new resource, we can use request.setAttribute() as we have a request object available.

SendRedirect

1. In case of sendRedirect, the request is transferred to another resource, to a different domain, or to a different server for further processing.

2. When you use sendRedirect, the container transfers the request to the client or browser, so the URL given inside the sendRedirect method is visible as a new request to the client.

3. In case of sendRedirect call, the old request and response objects are lost because it’s treated as new request by the browser.

4. In the address bar, we are able to see the new redirected address. It’s not transparent.

5. sendRedirect is slower because one extra round trip is required, because a completely new request is created and the old request object is lost. Two browser request are required.

6. But in sendRedirect, if we want to use the same data for a new resource we have to store the data in session or pass along with the URL.

Which one is good?

Its depends upon the scenario for which method is more useful.

If you want control is transfer to new server or context, and it is treated as completely new task, then we go for sendRedirect. Generally, a forward should be used if the operation can be safely repeated upon a browser reload of the web page and will not affect the result.

Nikita's point is an excellent one: don't confuse mature with bad. XML hasn't changed much.

JDOM would be another alternative to DOM4J.

Use the start command as follows.

start "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" http://www.google.com

It will be better to close chrome instances before you open a new one. You can do that as follows:

taskkill /IM chrome.exe
start "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" http://www.google.com

That'll work for you.

$(document).ready(function() {
  $('#div_one').bind('click', function() {
    $('#div_two').addClass('large');
  });
});

If I understood your question.

Or you can modify css directly:

var $speech = $('div.speech');
var currentSize = $speech.css('fontSize');
$speech.css('fontSize', '10px');

If you are looking for shortness :

read.csv(text="col1,col2")

so you don't need to specify the column names separately. You get the default column type logical until you fill the data frame.

UPDLOCK is used when you want to lock a row or rows during a select statement for a future update statement. The future update might be the very next statement in the transaction.

Other sessions can still see the data. They just cannot obtain locks that are incompatiable with the UPDLOCK and/or HOLDLOCK.

You use UPDLOCK when you wan to keep other sessions from changing the rows you have locked. It restricts their ability to update or delete locked rows.

You use HOLDLOCK when you want to keep other sessions from changing any of the data you are looking at. It restricts their ability to insert, update, or delete the rows you have locked. This allows you to run the query again and see the same results.

Well you can also do something interesting like this and do your job by using for loop

#suppose you have variable name
name = "Mr.Suryaa"
for index in range ( len ( name ) ):
    print ( name[index] ) #just like c and c++ 

Answer is

M r . S u r y a a

However since range() create a list of the values which is sequence thus you can directly use the name

for e in name:
    print(e)

This also produces the same result and also looks better and works with any sequence like list, tuple, and dictionary.

We have used tow Built in Functions ( BIFs in Python Community )

1) range() - range() BIF is used to create indexes Example

for i in range ( 5 ) :
can produce 0 , 1 , 2 , 3 , 4

2) len() - len() BIF is used to find out the length of given string

Please try this... This works for me..

In adapter,take a sparse boolean array.

SparseBooleanArray sparseBooleanArray;

In constructor initialise this,

   sparseBooleanArray=new SparseBooleanArray();

In bind holder add,

@Override
public void onBindViewHolder(DispositionViewHolder holder, final int position) {
   holder.tv_disposition.setText(dispList.get(position).getName());
    if(sparseBooleanArray.get(position,false))
    {
        holder.rd_disp.setChecked(true);
    }
    else
    {
        holder.rd_disp.setChecked(false);


    }
    setClickListner(holder,position);
}

private void setClickListner(final DispositionViewHolder holder, final int position) {
    holder.rd_disp.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            sparseBooleanArray.clear();
            sparseBooleanArray.put(position, true);
            notifyDataSetChanged();


        }
    });
}

rd_disp is radio button in xml file.

So when the recycler view load the items,in bindView Holder it check whether the sparseBooleanArray contain the value "true" correspnding to its position.

If the value returned is true then we set the radio button selection true.Else we set the selection false. In onclickHolder I have cleared the sparseArray and set the value true corresponding to that position. When I call notify datasetChange it again call the onBindViewHolder and the condition are checked again. This makes our selection to only select particular radio.

First I think int&const icr=i; is just int& icr = i, Modifier 'const' makes no sense(It just means you cannot make the reference refer to other variable).

const int x = 10;
// int& const y = x; // Compiler error here

Second, constant reference just means you cannot change the value of variable through reference.

const int x = 10;
const int& y = x;
//y = 20; // Compiler error here

Third, Constant references can bind right-value. Compiler will create a temp variable to bind the reference.

float x = 10;
const int& y = x;
const int& z = y + 10;
cout << (long long)&x << endl; //print 348791766212
cout << (long long)&y << endl; //print 348791766276
cout << (long long)&z << endl; //print 348791766340

First question:

Use the Intent to call another Activity. In the Manifest, you should add

<activity android:name="ListViewImage"></activity>
<activity android:name="com.company.listview.ListViewImage">
</activity>

And in your current activity,

btListe = (ImageButton)findViewById(R.id.Button_Liste);
    btListe.setOnClickListener(new OnClickListener()
    {    public void onClick(View v)
        {
            intent = new Intent(main.this, ListViewImage.class);
            startActivity(intent);
            finish();
        }
    });

Second question:

sendButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            String valueString = editValue.getText().toString();
            long value;
            if (valueString != null) {
                value = Long.parseLong(valueString);
            }
            else {
                value = 0;
            }

            Bundle sendBundle = new Bundle();
            sendBundle.putLong("value", value);

            Intent i = new Intent(Activity1.this, Activity2.class);
            i.putExtras(sendBundle);
            startActivity(i);

            finish();
        }
    });

and in Activity2:

 Bundle receiveBundle = this.getIntent().getExtras();
    final long receiveValue = receiveBundle.getLong("value");
    receiveValueEdit.setText(String.valueOf(receiveValue));
    callReceiverButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            Intent i = new Intent(Activity2.this, Receiver.class);
            i.putExtra("new value", receiveValue - 10);
        }
    });

Problem

There seems to be a problem with the original "duplicate line down" shortcut on Ubuntu, mostly due to a conflict with an already existing workspace related shortcut on the operating system.

Workaround

However, an easy workaround is to simply ctrl+c (copies the entire line) and ctrl+v (pastes the copied line on to a new one)... Effectively, giving you the same end result.

Wikipedia sums this up well:

On modern computer systems, localhost as a hostname translates to an IPv4 address in the 127.0.0.0/8 (loopback) net block, usually 127.0.0.1, or ::1 in IPv6.

The only difference is that it would be looking up in the DNS for the system what localhost resolves to. This lookup is really, really quick. For instance, to get to stackoverflow.com you typed in that to the address bar (or used a bookmarklet that pointed here). Either way, you got here through a hostname. localhost provides a similar functionality.

Answer to your first question is : both are similar,

Answer to your second question is: one-to-many --> a MAN(MAN table) may have more than one wife(WOMEN table) many-to-one --> more than one women have married one MAN.

Now if you want to relate this relation with two tables MAN and WOMEN, one MAN table row may have many relations with rows in the WOMEN table. hope it clear.

The request method getRequestDispatcher() can be used for referring to local servlets within single webapp.

Servlet context based getRequestDispatcher() method can used of referring servlets from other web applications deployed on SAME server.

You just need to keep track of a max value like this:

int maxValue = 0;

Then as you iterate through the numbers, keep setting the maxValue to the next value if it is greater than the maxValue:

if (value > maxValue) {
    maxValue = value;
}

Repeat in the opposite direction for minValue.

There is a MUCH easier solution to this than posted here, or in related threads. If you are using a webview (as I am), you can achieve this by executing a JAVASCRIPT function within it. If you are not using a webview, you might want to create a hidden one for this purpose. Here's a function that works in just about any browser (or webview) to kickoff ca installation (generally through the shared os cert repository, including on a Droid). It uses a nice trick with iFrames. Just pass the url to a .crt file to this function:

function installTrustedRootCert( rootCertUrl ){
    id = "rootCertInstaller";
    iframe = document.getElementById( id );
    if( iframe != null ) document.body.removeChild( iframe );
    iframe = document.createElement( "iframe" );
    iframe.id = id;
    iframe.style.display = "none";
    document.body.appendChild( iframe );
    iframe.src = rootCertUrl;
}

UPDATE:

The iframe trick works on Droids with API 19 and up, but older versions of the webview won't work like this. The general idea still works though - just download/open the file with a webview and then let the os take over. This may be an easier and more universal solution (in the actual java now):

 public static void installTrustedRootCert( final String certAddress ){
     WebView certWebView = new WebView( instance_ );
     certWebView.loadUrl( certAddress );
 }

Note that instance_ is a reference to the Activity. This works perfectly if you know the url to the cert. In my case, however, I resolve that dynamically with the server side software. I had to add a fair amount of additional code to intercept a redirection url and call this in a manner which did not cause a crash based on a threading complication, but I won't add all that confusion here...

I realize this is an old post but as I just ran into the same issue and had trouble finding the answer I thought I'd add a bit.

So @hammar's answer is correct. Using push.default simple is, in a way, like configuring tracking on your branches so you don't need to specify remotes and branches when pushing and pulling. The matching option will push all branches to their corresponding counterparts on the default remote (which is the first one that was set up unless you've configured your repo otherwise).

One thing I hope others find useful in the future is that I was running Git 1.8 on OS X Mountain Lion and never saw this error. Upgrading to Mavericks is what suddenly made it show up (running git --version will show git version 1.8.3.4 (Apple Git-47) which I'd never seen until the update to the OS.

This reply may be late but it may help users having similar problem. The opencv-contrib (available at https://github.com/opencv/opencv_contrib/releases) contains extra modules but the build procedure has to be done from core opencv (available at from https://github.com/opencv/opencv/releases) modules.

Follow below steps (assuming you are building it using CMake GUI)

1. Download openCV (from https://github.com/opencv/opencv/releases) and unzip it somewhere on your computer. Create build folder inside it

2. Download exra modules from OpenCV. (from https://github.com/opencv/opencv_contrib/releases). Ensure you download the same version.

3. Unzip the folder.

4. Open CMake

5. Click Browse Source and navigate to your openCV folder.

6. Click Browse Build and navigate to your build Folder.

7. Click the configure button. You will be asked how you would like to generate the files. Choose Unix-Makefile from the drop down menu and Click OK. CMake will perform some tests and return a set of red boxes appear in the CMake Window.

8. Search for "OPENCV_EXTRA_MODULES_PATH" and provide the path to modules folder (e.g. /Users/purushottam_d/Programs/OpenCV3_4_5_contrib/modules)

9. Click Configure again, then Click Generate.

10. Go to build folder

# cd build
# make
# sudo make install

11. This will install the opencv libraries on your computer.

Instead of using a Label use a text input:

<script type="text/javascript">
    onChange = function(ctrl) {
        var txt = document.getElementById("<%= txtResult.ClientID %>");
        if (txt){
            txt.value = ctrl.value;
        }           
    }
</script>

<asp:TextBox ID="txtTest" runat="server" onchange="onChange(this);" />      

<!-- pseudo label that will survive postback -->  
<input type="text" id="txtResult" runat="server" readonly="readonly" tabindex="-1000" style="border:0px;background-color:transparent;" />        

<asp:Button ID="btnTest" runat="server" Text="Test" />

Excel

1. In Excel, highlight and copy the data you want to paste into SQL.

SQL

2. Create the table with the desired column names and give you table a name. *Make sure Identity Specification is Yes, so it will auto increment your Identity column.
3. Find your table, and right click on it and choose Edit Top 200 Rows from the dialog-box.
4. Right click on the empty row with the * sign and select paste from the dialog-box

I think your problem is that it's closing the document that calls the macro before sending the command to quit the application.

Your solution in that case is to not send a command to close the workbook. Instead, you could set the "Saved" state of the workbook to true, which would circumvent any messages about closing an unsaved book. Note: this does not save the workbook; it just makes it look like it's saved.

ThisWorkbook.Saved = True

and then, right after

Application.Quit

I gave a similiar answer on another thread (Shrink a YouTube video to responsive width), but I guess my answers can help here as well.

It should be mentioned that it is an option to completely leave authentication issues to the front controller, e.g. an Apache Webserver and evaluate the HttpServletRequest.getRemoteUser() instead, which is the JAVA representation for the REMOTE_USER environment variable. This allows also sophisticated log in designs such as Shibboleth authentication. Filtering Requests to a servlet container through a web server is a good design for production environments, often mod_jk is used to do so.

You can use the pandas.DataFrame.quantile() function, as shown below.

import pandas as pd
import random

A = [ random.randint(0,100) for i in range(10) ]
B = [ random.randint(0,100) for i in range(10) ]

df = pd.DataFrame({ 'field_A': A, 'field_B': B })
df
#    field_A  field_B
# 0       90       72
# 1       63       84
# 2       11       74
# 3       61       66
# 4       78       80
# 5       67       75

df.field_A.mean()   # Same as df['field_A'].mean()
# 54.399999999999999

df.field_A.median() 
# 62.0

# You can call `quantile(i)` to get the i'th quantile,
# where `i` should be a fractional number.

df.field_A.quantile(0.1) # 10th percentile
# 11.9

df.field_A.quantile(0.5) # same as median
# 62.0

df.field_A.quantile(0.9) # 90th percentile

Need to specify two attributes, table-layout:fixed on table and white-space:nowrap; on the cells. You also need to move the overflow:hidden; to the cells too

table { width:250px;table-layout:fixed; }
table tr { height:1em;  }
td { overflow:hidden;white-space:nowrap;  } 

Here's a Demo . Tested in Firefox 3.5.3 and IE 7

Putting my two cents here. I wanted to do the same without hardcoding the URL for my specific request. So i came up with this solution.

To append 'api' to my baseURL, I have my default baseURL set as,

axios.defaults.baseURL = '/api/';

Then in my specific request, after explicitly setting the method and url, i set the baseURL to '/'

axios({
    method:'post',
    url:'logout',
    baseURL: '/',
   })
   .then(response => {
      window.location.reload();
   })
   .catch(error => {
       console.log(error);
   });

Once you have the initial ul, you can use the children() method, which will only consider the immediate children of the element. As @activa points out, one way to easily select the root element is to give it a class or an id. The following assumes you have a root ul with id root.

$('ul#root').children('li');

This question is quite old but still turns up on Google Search. The accepted question wasn't working for me anymore and seems to be aged. The latest information about cmake is written in the cmake FAQ.

There are various ways to change the path of your compiler. One way would be

Set the appropriate CMAKE_FOO_COMPILER variable(s) to a valid compiler name or full path on the command-line using cmake -D. For example:

cmake -G "Your Generator" -D CMAKE_C_COMPILER=gcc-4.2 -D CMAKE_CXX_COMPILER=g++-4.2 path/to/your/source

instead of gcc-4.2 you can write the path/to/your/compiler like this

 cmake -D CMAKE_C_COMPILER=/path/to/gcc/bin/gcc -D CMAKE_CXX_COMPILER=/path/to/gcc/bin/g++ .

Same problem here. Fixed! I installed the correct Java stuff, all for 64 bit, because my system is x64, and nothing happened. So I went to C:\Users\[my name] and deleted the directory .android that has been created the first time the SDK ran, apparently with some wrong configuration.

Then it worked. You can try that. Delete that folder or just move it to the desktop and run the SDK.

from @Przemek 's answer,

function listenClickOnly(element, callback, threshold=10) {
  let drag = 0;
  element.addEventListener('mousedown', () => drag = 0);
  element.addEventListener('mousemove', () => drag++);
  element.addEventListener('mouseup', e => {
    if (drag<threshold) callback(e);
  });
}

listenClickOnly(
  document,
  () => console.log('click'),
  10
);

It can be done using Quickselect Algorithm in O(n), do refer to Kth order statistics (randomized algorithms).

Check out the code below for decimal to hexadecimal conversion,

import java.util.Scanner;

public class DecimalToHexadecimal
{
   public static void main(String[] args)
   {
      int temp, decimalNumber;
      String hexaDecimal = "";
      char hexa[] = {'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};

      Scanner sc = new Scanner(System.in);
      System.out.print("Please enter decimal number : ");
      decimalNumber = sc.nextInt();

      while(decimalNumber > 0)
      {
         temp = decimalNumber % 16;
         hexaDecimal = hexa[temp] + hexaDecimal;
         decimalNumber = decimalNumber / 16;
      }

      System.out.print("The hexadecimal value of " + decimalNumber + " is : " + hexaDecimal);      
      sc.close();
   }
}

David's answer provides the meaning of each access modifier. As for when to use each, I'd suggest making public all classes and the methods of each class that are meant for external use (its API), and everything else private.

Over time you'll develop a sense for when to make some classes package-private and when to declare certain methods protected for use in subclasses.

I found possible answer. You have core-js version 3.0, and this version doesn't have separate folders for ES6 and ES7; that's why the application cannot find correct paths.

To resolve this error, you can downgrade the core-js version to 2.5.7. This version produces correct catalogs structure, with separate ES6 and ES7 folders.

To downgrade the version, simply run:

npm i -S [email protected]

In my case, with Angular, this works ok.

You can just add '\r' at the end of the string plus a comma at the end of print function. For example:

print(os.path.getsize(file_name)/1024+'KB / '+size+' KB downloaded!\r'),

Doing this with POSIX is tricky:

• POSIX Sed does not support \r or \15. Even if it did, the in place option -i is not POSIX

• POSIX Awk does support \r and \15, however the -i inplace option is not POSIX

• d2u and dos2unix are not POSIX utilities, but ex is

• POSIX ex does not support \r, \15, \n or \12

To remove carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\r","");print>ARGV[1]}' file

To add carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\n","\r&");print>ARGV[1]}' file

Wont the below basic approach doesn't suffice your requirements?

HTML Code having a div

<div id="mydiv" onscroll='myMethod();'>

JS will have below code

function myMethod(){ alert(1); }

Use the .Clear method.

Sheets("Test").Range("A1:C3").Clear

MSDN documentation here.

try this:

key=key.replace(/ /g,"_");

that'll do a global find/replace

javascript replace

Bootstrap-theme.css is the additional CSS file, which is optional for you to use. It gives 3D effects on the buttons and some other elements.

If none of the above worked for you, you can specify the module explicitly.

Directory:

+-- Project
¦     +-- Dir
¦     ¦    +-- __init__.py
¦     ¦    +-- module.py
¦     ¦    +-- standalone.py

Solution:

#in standalone.py
from Project.Dir.module import ...

module - the module to be imported

request.data will be empty if request.headers["Content-Type"] is recognized as form data, which will be parsed into request.form. To get the raw data regardless of content type, use request.get_data().

request.data calls request.get_data(parse_form_data=True), which results in the different behavior for form data.

You can do this replacing position:absolute; by position:fixed;.

Assuming you have Notepad++, an often-missed feature is 'Find in files', which is extremely fast and comes with filters, regular expressions, replace and all the N++ goodies.

If you want to pass just the index.php ( no other php file will be passed to fastcgi ) to fastcgi in case you have routes like this in a framework like codeigniter

$route["/download.php"] = "controller/method";


location ~ index\.php$ {
        fastcgi_pass 127.0.0.1:9000;
        include fastcgi.conf;
}

Think of it as two different ways of finding your way in a phonebook. A linear search is starting at the beginning, reading every name until you find what you're looking for. A binary search, on the other hand, is when you open the book (usually in the middle), look at the name on top of the page, and decide if the name you're looking for is bigger or smaller than the one you're looking for. If the name you're looking for is bigger, then you continue searching the upper part of the book in this very fashion.

follow steps (CentOs):

1. bluetoothctl
2. devices
3. scan on
4. pair 34:88:5D:51:5A:95 (34:88:5D:51:5A:95 is my device code,replace it with yours)
5. trust 34:88:5D:51:5A:95
6. connect 34:88:5D:51:5A:95

One line only ! path and line are Strings

import java.nio.file.Files;
import java.nio.file.Paths;

Files.write(Paths.get(path), lines.getBytes());

In plain C you can use a pointer/size combination in your API.

void doSomething(MyStruct* mystruct, size_t numElements)
{
    for (size_t i = 0; i < numElements; ++i)
    {
        MyStruct current = mystruct[i];
        handleElement(current);
    }
}

Using pointers is the closest to call-by-reference available in C.

General rule is the following:

• If select contains single expression and it's an entity, then result is that entity
• If select contains single expression and it's a primitive, then result is that primitive
• If select contains multiple expressions, then result is Object[] containing the corresponding primitives/entities

So, in your case list is a List<Object[]>.

For Swift i checked this answer in iOS 9.0 and iOS 11 also (Xcode 9.3)

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

Here you need to add top, bottom, right and left constraints

I use __get (and public properties) as much as possible, because they make code much more readable. Compare:

this code unequivocally says what i'm doing:

echo $user->name;

this code makes me feel stupid, which i don't enjoy:

function getName() { return $this->_name; }
....

echo $user->getName();

The difference between the two is particularly obvious when you access multiple properties at once.

echo "
    Dear $user->firstName $user->lastName!
    Your purchase:
        $product->name  $product->count x $product->price
"

and

echo "
    Dear " . $user->getFirstName() . " " . $user->getLastName() . "
    Your purchase: 
        " . $product->getName() . " " . $product->getCount() . "  x " . $product->getPrice() . " ";

Whether $a->b should really do something or just return a value is the responsibility of the callee. For the caller, $user->name and $user->accountBalance should look the same, although the latter may involve complicated calculations. In my data classes i use the following small method:

 function __get($p) { 
      $m = "get_$p";
      if(method_exists($this, $m)) return $this->$m();
      user_error("undefined property $p");
 }

when someone calls $obj->xxx and the class has get_xxx defined, this method will be implicitly called. So you can define a getter if you need it, while keeping your interface uniform and transparent. As an additional bonus this provides an elegant way to memorize calculations:

  function get_accountBalance() {
      $result = <...complex stuff...>
      // since we cache the result in a public property, the getter will be called only once
      $this->accountBalance = $result;
  }

  ....


   echo $user->accountBalance; // calculate the value
   ....
   echo $user->accountBalance; // use the cached value

Bottom line: php is a dynamic scripting language, use it that way, don't pretend you're doing Java or C#.

A variation using just standard color code:

android:textColor="#ff0000"

Just use:

<?php
    include("/path/to/file.html");
?>

That will echo it as well. This also has the benefit of executing any PHP in the file.

If you need to do anything with the contents, use file_get_contents(),

For example,

<?php
    $pagecontents = file_get_contents("/path/to/file.html");

    echo str_replace("Banana", "Pineapple", $pagecontents);

?>

This doesn't execute code in that file, so be careful if you expect that to work.

I usually use:

include($_SERVER['DOCUMENT_ROOT']."/path/to/file/as/in/url.html");

as then I can move files without breaking the includes.

To make it simpler

SELECT *,MIN(price) FROM prod LIMIT 1

• Put * so it will display the all record of the minimum value

yo can extend your JS with a select method like this

Array.prototype.select = function(closure){
    for(var n = 0; n < this.length; n++) {
        if(closure(this[n])){
            return this[n];
        }
    }

    return null;
};

now you can use this:

var x = [1,2,3,4];

var a = x.select(function(v) {
    return v == 2;
});

console.log(a);

or for objects in a array

var x = [{id: 1, a: true},
    {id: 2, a: true},
    {id: 3, a: true},
    {id: 4, a: true}];

var a = x.select(function(obj) {
    return obj.id = 2;
});

console.log(a);

[x * 0.1 for x in range(0, 10)] 

in Python 2.7x gives you the result of:

[0.0, 0.1, 0.2, 0.30000000000000004, 0.4, 0.5, 0.6000000000000001, 0.7000000000000001, 0.8, 0.9]

but if you use:

[ round(x * 0.1, 1) for x in range(0, 10)]

gives you the desired:

[0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9]

Answer in Swift:

Add delegate UIGestureRecognizerDelegate to your UITableViewController.

Within UITableViewController:

override func viewDidLoad() {
    super.viewDidLoad()

    let longPressGesture:UILongPressGestureRecognizer = UILongPressGestureRecognizer(target: self, action: "handleLongPress:")
    longPressGesture.minimumPressDuration = 1.0 // 1 second press
    longPressGesture.delegate = self
    self.tableView.addGestureRecognizer(longPressGesture)

}

And the function:

func handleLongPress(longPressGesture:UILongPressGestureRecognizer) {

    let p = longPressGesture.locationInView(self.tableView)
    let indexPath = self.tableView.indexPathForRowAtPoint(p)

    if indexPath == nil {
        print("Long press on table view, not row.")
    }
    else if (longPressGesture.state == UIGestureRecognizerState.Began) {
        print("Long press on row, at \(indexPath!.row)")
    }

}

One could also do a raise NotImplementedError() inside the child method of an @abstractmethod-decorated base class method.

Imagine writing a control script for a family of measurement modules (physical devices). The functionality of each module is narrowly-defined, implementing just one dedicated function: one could be an array of relays, another a multi-channel DAC or ADC, another an ammeter etc.

Much of the low-level commands in use would be shared between the modules for example to read their ID numbers or to send a command to them. Let's see what we have at this point:

Base Class

from abc import ABC, abstractmethod  #< we'll make use of these later

class Generic(ABC):
    ''' Base class for all measurement modules. '''

    # Shared functions
    def __init__(self):
        # do what you must...

    def _read_ID(self):
        # same for all the modules

    def _send_command(self, value):
        # same for all the modules

Shared Verbs

We then realise that much of the module-specific command verbs and, therefore, the logic of their interfaces is also shared. Here are 3 different verbs whose meaning would be self-explanatory considering a number of target modules.

• get(channel)

• relay: get the on/off status of the relay on channel

• DAC: get the output voltage on channel

• ADC: get the input voltage on channel

• enable(channel)

• relay: enable the use of the relay on channel

• DAC: enable the use of the output channel on channel

• ADC: enable the use of the input channel on channel

• set(channel)

• relay: set the relay on channel on/off

• DAC: set the output voltage on channel

• ADC: hmm... nothing logical comes to mind.

Shared Verbs Become Enforced Verbs

I'd argue that there is a strong case for the above verbs to be shared across the modules as we saw that their meaning is evident for each one of them. I'd continue writing my base class Generic like so:

class Generic(ABC):  # ...continued
    
    @abstractmethod
    def get(self, channel):
        pass

    @abstractmethod
    def enable(self, channel):
        pass

    @abstractmethod
    def set(self, channel):
        pass

Subclasses

We now know that our subclasses will all have to define these methods. Let's see what it could look like for the ADC module:

class ADC(Generic):

    def __init__(self):
        super().__init__()  #< applies to all modules
        # more init code specific to the ADC module
    
    def get(self, channel):
        # returns the input voltage measured on the given 'channel'

    def enable(self, channel):
        # enables accessing the given 'channel'

You may now be wondering:

But this won't work for the ADC module as set makes no sense there as we've just seen this above!

You're right: not implementing set is not an option as Python would then fire the error below when you tried to instantiate your ADC object.

TypeError: Can't instantiate abstract class 'ADC' with abstract methods 'set'

So you must implement something, because we made set an enforced verb (aka '@abstractmethod'), which is shared by two other modules but, at the same time, you must also not implement anything as set does not make sense for this particular module.

NotImplementedError to the Rescue

By completing the ADC class like this:

class ADC(Generic): # ...continued

    def set(self, channel):
        raise NotImplementedError("Can't use 'set' on an ADC!")

You are doing three very good things at once:

1. You are protecting a user from erroneously issuing a command ('set') that is not (and shouldn't!) be implemented for this module.
2. You are telling them explicitly what the problem is (see TemporalWolf's link about 'Bare exceptions' for why this is important)
3. You are protecting the implementation of all the other modules for which the enforced verbs do make sense. I.e. you ensure that those modules for which these verbs do make sense will implement these methods and that they will do so using exactly these verbs and not some other ad-hoc names.

You are better off using a native array instead of an object literal with number-like properties, so that numbering (as well as numerous other array functions) are taken care of off-the-shelf.

What you are looking for here is an inline interface definition for your array that defines every element in that array, whether initially present or introduced later:

let userTestStatus: { id: number, name: string }[] = [
    { "id": 0, "name": "Available" },
    { "id": 1, "name": "Ready" },
    { "id": 2, "name": "Started" }
];

userTestStatus[34978].nammme; // Error: Property 'nammme' does not exist on type [...]

If you are initializing your array with values right away, the explicit type definition is not a necessity; TypeScript can automatically infer most element types from the initial assignment:

let userTestStatus = [
    { "id": 0, "name": "Available" },
    ...
];

userTestStatus[34978].nammme; // Error: Property 'nammme' does not exist on type [...]

put .; at classpath value in beginning..it will start working...it happens because it searches the class file in classpath which is mentioned in path variable.

When creating a project from a sample,while not importing the existing project is good (prevents clashes with gradle, .idea, .iml, build, jars and apks, i.e. all unnecessary build-generated files), after creating a new project, copying and pasting all relevant resources, I'd recommend :

checking packages and imports from packages within the project {AndroidManifest declaration and all imports in java classes}, all resources (drawable, mip-map, layouts and menus & your build.gradle (a sample of build.gradle to use with the latest sdk can be provided on request)) to see if they are there & if declared strings and ids actually exist and have been used, after which your only error should be the question asked:

Bulid->Clean Project

Tools->Android->Sync Project with Gradle Files

File->Invalidate Caches and Restart

In worst cases restarting your machine helps.

The above should work. Feel free to ask questions if necessary, i.e. post comments.

You can SSH in to docker container as root by using

docker exec -it --user root <container_id> /bin/bash

Then change root password using this

passwd root

Make sure sudo is installed check by entering

sudo

if it is not installed install it

apt-get install sudo

If you want to give sudo permissions for user dev you can add user dev to sudo group

usermod -aG sudo dev

Now you'll be able to run sudo level commands from your dev user while inside the container or else you can switch to root inside the container by using the password you set earlier.

To test it login as user dev and list the contents of root directory which is normally only accessible to the root user.

sudo ls -la /root

Enter password for dev

If your user is in the proper group and you entered the password correctly, the command that you issued with sudo should run with root privileges.

Using javascript function it is easier to get all the attributes of an element in NamedArrayFormat.

$("#myTestDiv").click(function(){_x000D_
  var attrs = document.getElementById("myTestDiv").attributes;_x000D_
  $.each(attrs,function(i,elem){_x000D_
    $("#attrs").html(    $("#attrs").html()+"<br><b>"+elem.name+"</b>:<i>"+elem.value+"</i>");_x000D_
  });_x000D_
});

If you don't want to use Windows Forms nor edit manifest files, I came up with a very simple hack using WPF's SaveAs dialog for actually selecting a directory.

No using directive needed, you may simply copy-paste the code below !

It should still be very user-friendly and most people will never notice.

The idea comes from the fact that we can change the title of that dialog, hide files, and work around the resulting filename quite easily.

It is a big hack for sure, but maybe it will do the job just fine for your usage...

In this example I have a textbox object to contain the resulting path, but you may remove the related lines and use a return value if you wish...

// Create a "Save As" dialog for selecting a directory (HACK)
var dialog = new Microsoft.Win32.SaveFileDialog();
dialog.InitialDirectory = textbox.Text; // Use current value for initial dir
dialog.Title = "Select a Directory"; // instead of default "Save As"
dialog.Filter = "Directory|*.this.directory"; // Prevents displaying files
dialog.FileName = "select"; // Filename will then be "select.this.directory"
if (dialog.ShowDialog() == true) {
    string path = dialog.FileName;
    // Remove fake filename from resulting path
    path = path.Replace("\\select.this.directory", "");
    path = path.Replace(".this.directory", "");
    // If user has changed the filename, create the new directory
    if (!System.IO.Directory.Exists(path)) {
        System.IO.Directory.CreateDirectory(path);
    }
    // Our final value is in path
    textbox.Text = path;
}

The only issues with this hack are :

• Acknowledge button still says "Save" instead of something like "Select directory", but in a case like mines I "Save" the directory selection so it still works...
• Input field still says "File name" instead of "Directory name", but we can say that a directory is a type of file...
• There is still a "Save as type" dropdown, but its value says "Directory (*.this.directory)", and the user cannot change it for something else, works for me...

Most people won't notice these, although I would definitely prefer using an official WPF way if microsoft would get their heads out of their asses, but until they do, that's my temporary fix.

The main method is the entry point of a Java application.

Specifically?when the Java Virtual Machine is told to run an application by specifying its class (by using the java application launcher), it will look for the main method with the signature of public static void main(String[]).

From Sun's java command page:

The java tool launches a Java application. It does this by starting a Java runtime environment, loading a specified class, and invoking that class's main method.

The method must be declared public and static, it must not return any value, and it must accept a String array as a parameter. The method declaration must look like the following:

public static void main(String args[])

For additional resources on how an Java application is executed, please refer to the following sources:

1. Chapter 12: Execution from the Java Language Specification, Third Edition.
2. Chapter 5: Linking, Loading, Initializing from the Java Virtual Machine Specifications, Second Edition.
3. A Closer Look at the "Hello World" Application from the Java Tutorials.

The run method is the entry point for a new Thread or an class implementing the Runnable interface. It is not called by the Java Virutal Machine when it is started up by the java command.

As a Thread or Runnable itself cannot be run directly by the Java Virtual Machine, so it must be invoked by the Thread.start() method. This can be accomplished by instantiating a Thread and calling its start method in the main method of the application:

public class MyRunnable implements Runnable
{
    public void run()
    {
        System.out.println("Hello World!");
    }

    public static void main(String[] args)
    {
        new Thread(new MyRunnable()).start();
    }
}

For more information and an example of how to start a subclass of Thread or a class implementing Runnable, see Defining and Starting a Thread from the Java Tutorials.

The init method is the first method called in an Applet or JApplet.

When an applet is loaded by the Java plugin of a browser or by an applet viewer, it will first call the Applet.init method. Any initializations that are required to use the applet should be executed here. After the init method is complete, the start method is called.

For more information about when the init method of an applet is called, please read about the lifecycle of an applet at The Life Cycle of an Applet from the Java Tutorials.

If your SQL doesn't support NULLS FIRST or NULLS LAST, the simplest way to do this is to use the value IS NULL expression:

ORDER BY Next_Contact_Date IS NULL, Next_Contact_Date

to put the nulls at the end (NULLS LAST) or

ORDER BY Next_Contact_Date IS NOT NULL, Next_Contact_Date

to put the nulls at the front. This doesn't require knowing the type of the column and is easier to read than the CASE expression.

EDIT: Alas, while this works in other SQL implementations like PostgreSQL and MySQL, it doesn't work in MS SQL Server. I didn't have a SQL Server to test against and relied on Microsoft's documentation and testing with other SQL implementations. According to Microsoft, value IS NULL is an expression that should be usable just like any other expression. And ORDER BY is supposed to take expressions just like any other statement that takes an expression. But it doesn't actually work.

The best solution for SQL Server therefore appears to be the CASE expression.

 <div onScrollCapture={() => this._onScrollEvent()}></div>

 _onScrollEvent = (e)=>{
     const top = e.nativeEvent.target.scrollTop;
     console.log(top); 
}

            permutations.append([array[i], *p])
    return permutations

Yield implementation:

def getPermutations(array):
    if len(array) == 1:
        yield array
    else:
        for i in range(len(array)):
            perms = getPermutations(array[:i] + array[i+1:])
            for p in perms:
                yield [array[i], *p]

The basic idea is to go over all the elements in the array for the 1st position, and then in 2nd position go over all the rest of the elements without the chosen element for the 1st, etc. You can do this with recursion, where the stop criteria is getting to an array of 1 element - in which case you return that array.

In addition to the answers above:

$ python3 -m timeit -s 'import os' 'os.environ.get("TERM_PROGRAM")'
200000 loops, best of 5: 1.65 usec per loop

$ python3 -m timeit -s 'import os' 'os.getenv("TERM_PROGRAM")'
200000 loops, best of 5: 1.83 usec per loop

I'm on a roll, just found an even simpler way to do it using the by keyword in the hist method:

df['N'].hist(by=df['Letter'])

That's a very handy little shortcut for quickly scanning your grouped data!

How to iterate efficiently

If you really have to iterate a Pandas dataframe, you will probably want to avoid using iterrows(). There are different methods and the usual iterrows() is far from being the best. itertuples() can be 100 times faster.

In short:

• As a general rule, use df.itertuples(name=None). In particular, when you have a fixed number columns and less than 255 columns. See point (3)
• Otherwise, use df.itertuples() except if your columns have special characters such as spaces or '-'. See point (2)
• It is possible to use itertuples() even if your dataframe has strange columns by using the last example. See point (4)
• Only use iterrows() if you cannot the previous solutions. See point (1)

Different methods to iterate over rows in a Pandas dataframe:

Generate a random dataframe with a million rows and 4 columns:

    df = pd.DataFrame(np.random.randint(0, 100, size=(1000000, 4)), columns=list('ABCD'))
    print(df)

1) The usual iterrows() is convenient, but damn slow:

start_time = time.clock()
result = 0
for _, row in df.iterrows():
    result += max(row['B'], row['C'])

total_elapsed_time = round(time.clock() - start_time, 2)
print("1. Iterrows done in {} seconds, result = {}".format(total_elapsed_time, result))

2) The default itertuples() is already much faster, but it doesn't work with column names such as My Col-Name is very Strange (you should avoid this method if your columns are repeated or if a column name cannot be simply converted to a Python variable name).:

start_time = time.clock()
result = 0
for row in df.itertuples(index=False):
    result += max(row.B, row.C)

total_elapsed_time = round(time.clock() - start_time, 2)
print("2. Named Itertuples done in {} seconds, result = {}".format(total_elapsed_time, result))

3) The default itertuples() using name=None is even faster but not really convenient as you have to define a variable per column.

start_time = time.clock()
result = 0
for(_, col1, col2, col3, col4) in df.itertuples(name=None):
    result += max(col2, col3)

total_elapsed_time = round(time.clock() - start_time, 2)
print("3. Itertuples done in {} seconds, result = {}".format(total_elapsed_time, result))

4) Finally, the named itertuples() is slower than the previous point, but you do not have to define a variable per column and it works with column names such as My Col-Name is very Strange.

start_time = time.clock()
result = 0
for row in df.itertuples(index=False):
    result += max(row[df.columns.get_loc('B')], row[df.columns.get_loc('C')])

total_elapsed_time = round(time.clock() - start_time, 2)
print("4. Polyvalent Itertuples working even with special characters in the column name done in {} seconds, result = {}".format(total_elapsed_time, result))

Output:

         A   B   C   D
0       41  63  42  23
1       54   9  24  65
2       15  34  10   9
3       39  94  82  97
4        4  88  79  54
...     ..  ..  ..  ..
999995  48  27   4  25
999996  16  51  34  28
999997   1  39  61  14
999998  66  51  27  70
999999  51  53  47  99

[1000000 rows x 4 columns]

1. Iterrows done in 104.96 seconds, result = 66151519
2. Named Itertuples done in 1.26 seconds, result = 66151519
3. Itertuples done in 0.94 seconds, result = 66151519
4. Polyvalent Itertuples working even with special characters in the column name done in 2.94 seconds, result = 66151519

This article is a very interesting comparison between iterrows and itertuples

If you're working in a virtual environment (virtualenv), you'll definitely need to update the python.lintint.pylintPath setting (and probably the python.pythonPath setting, as well, if you haven't already) if you want linting to work, like this:

// File "settings.json" (workspace-specific one is probably best)
{
    // ...
    "python.linting.pylintPath": "C:/myproject/venv/Scripts/pylint.exe",
    "python.pythonPath": "C:/myproject/venv/Scripts/python.exe",
    // ...
}

That's for Windows, but other OSs are similar. The .exe extension was necessary for it to work for me on Windows, even though it's not required when actually running it in the console.

If you just want to disable it, then use the python.linting.pylintEnabled": false setting as mentioned in Ben Delaney's answer.

If you're putting a <meta> tag in your css files, you're doing something wrong. The <meta> tag belongs in your html files, and tells the browser how the html is encoded, it doesn't say anything about the css, which is a separate file. You could conceivably have completely different encodings for your html and css, although I can't imagine this would be a good idea.

Although approved answer is correct, I want to show a bit different approach (based on this answer).

Vscode can automatically choose correct anaconda environment if you start vscode from it. Just add to user/workspace settings:

{
    "python.pythonPath": "C:/<proper anaconda path>/Anaconda3/envs/${env:CONDA_DEFAULT_ENV}/python"
}

It works on Windows, macOS and probably Unix. Further read on variable substitution in vscode: here.

For using FusedLocationProviderClient with Google Play Services 11 and higher:

see here: How to get current Location in GoogleMap using FusedLocationProviderClient

For using (now deprecated) FusedLocationProviderApi:

If your project uses Google Play Services 10 or lower, using the FusedLocationProviderApi is the optimal choice.

The FusedLocationProviderApi offers less battery drain than the old open source LocationManager API. Also, if you're already using Google Play Services for Google Maps, there's no reason not to use it.

Here is a full Activity class that places a Marker at the current location, and also moves the camera to the current position.

It also checks for the Location permission at runtime for Android 6 and later (Marshmallow, Nougat, Oreo). In order to properly handle the Location permission runtime check that is necessary on Android M/Android 6 and later, you need to ensure that the user has granted your app the Location permission before calling mGoogleMap.setMyLocationEnabled(true) and also before requesting location updates.

Result:

Show permission explanation if needed using an AlertDialog (this happens if the user denies a permission request, or grants the permission and then later revokes it in the settings):

Prompt the user for Location permission by calling ActivityCompat.requestPermissions():

Move camera to current location and place Marker when the Location permission is granted:

This is extremely IMPORTANT. One of the the options i'm exploring this afternoon is using javascript callback methods rather than addEventListeners since that doesn't seem to bind correctly either. Getting all the elements ready before page load WITHOUT a page refresh is critical.

If anyone can expand upon this please do - as in, did you use a settimeout, a wait, a callback, or an addEventListener method to get the desired result. Which one and why?

All you have to do is: $variable =NULL; // and pass it in the insert query. This will store the value as NULL in mysql db

While the answers in the thread are all true enough, I cannot resist the urge to tell you that it in fact is possible to have an anonymous class implement an interface, even though it takes a bit of creative cheating to get there.

Back in 2008 I was writing a custom LINQ provider for my then employer, and at one point I needed to be able to tell "my" anonymous classes from other anonymous ones, which meant having them implement an interface that I could use to type check them. The way we solved it was by using aspects (we used PostSharp), to add the interface implementation directly in the IL. So, in fact, letting anonymous classes implement interfaces is doable, you just need to bend the rules slightly to get there.

Any changes you commit, like deleting all your project files, will still be in place after a pull. All a pull does is merge the latest changes from somewhere else into your own branch, and if your branch has deleted everything, then at best you'll get merge conflicts when upstream changes affect files you've deleted. So, in short, yes everything is up to date.

If you describe what outcome you'd like to have instead of "all files deleted", maybe someone can suggest an appropriate course of action.

Update:

GET THE MOST RECENT OF THE CODE ON MY SYSTEM

What you don't seem to understand is that you already have the most recent code, which is yours. If what you really want is to see the most recent of someone else's work that's on the master branch, just do:

git fetch upstream
git checkout upstream/master

Note that this won't leave you in a position to immediately (re)start your own work. If you need to know how to undo something you've done or otherwise revert changes you or someone else have made, then please provide details. Also, consider reading up on what version control is for, since you seem to misunderstand its basic purpose.

echo "0 * * * * docker system prune --force >/dev/null 2>&1" | sudo tee /etc/cron.daily/dockerprune

BE CAREFUL with those other answers as they will not play properly with bodyParser if you're looking to also support json, urlencoded, etc. To get it to work with bodyParser you should condition your handler to only register on the Content-Type header(s) you care about, just like bodyParser itself does.

To get the raw body content of a request with Content-Type: "text/plain" into req.rawBody you can do:

app.use(function(req, res, next) {
  var contentType = req.headers['content-type'] || ''
    , mime = contentType.split(';')[0];

  if (mime != 'text/plain') {
    return next();
  }

  var data = '';
  req.setEncoding('utf8');
  req.on('data', function(chunk) {
    data += chunk;
  });
  req.on('end', function() {
    req.rawBody = data;
    next();
  });
});

Here's an algorithm that returns a unique readable filename based on the original supplied. If the original file exists, it incrementally tries to append an index to the filename until it finds one that doesn't exist. It reads the existing filenames into a HashSet to check for collisions so it's pretty quick (a few hundred filenames per second on my machine), it's thread safe too, and doesn't suffer from race conditions.

For example, if you pass it test.txt, it will attempt to create files in this order:

test.txt
test (2).txt
test (3).txt

etc. You can specify the maximum attempts or just leave it at the default.

Here's a complete example:

class Program
{
    static FileStream CreateFileWithUniqueName(string folder, string fileName, 
        int maxAttempts = 1024)
    {
        // get filename base and extension
        var fileBase = Path.GetFileNameWithoutExtension(fileName);
        var ext = Path.GetExtension(fileName);
        // build hash set of filenames for performance
        var files = new HashSet<string>(Directory.GetFiles(folder));

        for (var index = 0; index < maxAttempts; index++)
        {
            // first try with the original filename, else try incrementally adding an index
            var name = (index == 0)
                ? fileName
                : String.Format("{0} ({1}){2}", fileBase, index, ext);

            // check if exists
            var fullPath = Path.Combine(folder, name);
            if(files.Contains(fullPath))
                continue;

            // try to create the file
            try
            {
                return new FileStream(fullPath, FileMode.CreateNew, FileAccess.Write);
            }
            catch (DirectoryNotFoundException) { throw; }
            catch (DriveNotFoundException) { throw; }
            catch (IOException) 
            {
                // Will occur if another thread created a file with this 
                // name since we created the HashSet. Ignore this and just
                // try with the next filename.
            } 
        }

        throw new Exception("Could not create unique filename in " + maxAttempts + " attempts");
    }

    static void Main(string[] args)
    {
        for (var i = 0; i < 500; i++)
        {
            using (var stream = CreateFileWithUniqueName(@"c:\temp\", "test.txt"))
            {
                Console.WriteLine("Created \"" + stream.Name + "\"");
            }
        }

        Console.ReadKey();
    }
}

Swift 3 & 4:

You can create a extension on DispatchQueue and add function delay which uses DispatchQueue asyncAfter function internally

extension DispatchQueue {
    static func delay(_ delay: DispatchTimeInterval, closure: @escaping () -> ()) {
        let timeInterval = DispatchTime.now() + delay
        DispatchQueue.main.asyncAfter(deadline: timeInterval, execute: closure)
    }
}

use:

DispatchQueue.delay(.seconds(1)) {
    print("This is after delay")
}

Turning Hardware Acceleration OFF seems to be the setting that affects popups & dialogs.

Chrome was continually hiding Dialog Windows when I needed to respond Yes or No to things, also when I needed to Rename folders in my bookmarks panel. After weeks of doing this. I disabled all the Chrome helpers in Settings, Also In windows 10 I switched Window Snapping off. It has done something to put the popups and dialogs back in the Viewport.

When this bug is happening, I was able to shut a tab by first pressing Enter before clicking the tab close X button. The browser had an alert box, hidden which needed a response from the user.

Switching Hardware Accleration Off and back On, Killing the Chrome process and switching all the other Helpers Off and back has fixed it for me... It must be in chrome itself because Ive just gone into a Chrome window in the Mac and it has now stopped the problem, without any intervention. Im guessing flicking the chrome settings on/off/on has caused it to reposition the dialogs. I cant get the browser to repeat the fault now...

Here is another solution you could have used. It is working in my app.

      @Override
      public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        android.support.v7.app.ActionBar actionBar =getSupportActionBar();
        actionBar.setDisplayHomeAsUpEnabled(true);            
        setContentView(R.layout.activity_main)

Then you can get rid of that import for the one line ActionBar use.

The first basic thing to understand is the difference in architectures.

One end you have the MVC architecture, which is based on your normal web app, using web pages, and the browser makes a request for a page:

Browser <---> Controller <---> Model
               |      |
               +-View-+

The browser makes a request, the controller (@Controller) gets the model (@Entity), and creates the view (JSP) from the model and the view is returned back to the client. This is the basic web app architecture.

On the other end, you have a RESTful architecture. In this case, there is no View. The Controller only sends back the model (or resource representation, in more RESTful terms). The client can be a JavaScript application, a Java server application, any application in which we expose our REST API to. With this architecture, the client decides what to do with this model. Take for instance Twitter. Twitter as the Web (REST) API, that allows our applications to use its API to get such things as status updates, so that we can use it to put that data in our application. That data will come in some format like JSON.

That being said, when working with Spring MVC, it was first built to handle the basic web application architecture. There are may different method signature flavors that allow a view to be produced from our methods. The method could return a ModelAndView where we explicitly create it, or there are implicit ways where we can return some arbitrary object that gets set into model attributes. But either way, somewhere along the request-response cycle, there will be a view produced.

But when we use @ResponseBody, we are saying that we do not want a view produced. We just want to send the return object as the body, in whatever format we specify. We wouldn't want it to be a serialized Java object (though possible). So yes, it needs to be converted to some other common type (this type is normally dealt with through content negotiation - see link below). Honestly, I don't work much with Spring, though I dabble with it here and there. Normally, I use

@RequestMapping(..., produces = MediaType.APPLICATION_JSON_VALUE)

to set the content type, but maybe JSON is the default. Don't quote me, but if you are getting JSON, and you haven't specified the produces, then maybe it is the default. JSON is not the only format. For instance, the above could easily be sent in XML, but you would need to have the produces to MediaType.APPLICATION_XML_VALUE and I believe you need to configure the HttpMessageConverter for JAXB. As for the JSON MappingJacksonHttpMessageConverter configured, when we have Jackson on the classpath.

I would take some time to learn about Content Negotiation. It's a very important part of REST. It'll help you learn about the different response formats and how to map them to your methods.

There's a plugin that extends CSS to include some non-standard features that can really help when designing websites. It's called EQCSS.

One of the things EQCSS adds is a parent selector. It works in all browsers, Internet Explorer 8 and up. Here's the format:

@element 'a.active' {
  $parent {
    background: red;
  }
}

So here we've opened an element query on every element a.active, and for the styles inside that query, things like $parent make sense, because there's a reference point. The browser can find the parent, because it's very similar to parentNode in JavaScript.

Here's a demo of $parent and another $parent demo that works in Internet Explorer 8, as well as a screenshot in case you don't have Internet Explorer 8 around to test with.

EQCSS also includes meta-selectors: $prev for the element before a selected element and $this for only those elements that match an element query, and more.

This is an old question, but attempting to apply a new field (either NEWID() or ORDER BY rand()) to a table with a large number of rows would be prohibitively expensive. If you have incremental, unique IDs (and do not have any holes) it will be more efficient to calculate the X # of IDs to be selected instead of applying a GUID or similar to every single row and then taking the top X # of.

DECLARE @minValue int;
DECLARE @maxValue int;
SELECT @minValue = min(id), @maxValue = max(id) from [TABLE];

DECLARE @randomId1 int, @randomId2 int, @randomId3 int, @randomId4 int, @randomId5 int
SET @randomId1 = ((@maxValue + 1) - @minValue) * Rand() + @minValue
SET @randomId2 = ((@maxValue + 1) - @minValue) * Rand() + @minValue
SET @randomId3 = ((@maxValue + 1) - @minValue) * Rand() + @minValue
SET @randomId4 = ((@maxValue + 1) - @minValue) * Rand() + @minValue
SET @randomId5 = ((@maxValue + 1) - @minValue) * Rand() + @minValue

--select @maxValue as MaxValue, @minValue as MinValue
--  , @randomId1 as SelectedId1
--  , @randomId2 as SelectedId2
--  , @randomId3 as SelectedId3
--  , @randomId4 as SelectedId4
--  , @randomId5 as SelectedId5

select * from [TABLE] el
where el.id in (@randomId1, @randomId2, @randomId3, @randomId4, @randomId5)

If you wanted to select many more rows I would look into populating a #tempTable with an ID and a bunch of rand() values then using each rand() value to scale to the min-max values. That way you do not have to define all of the @randomId1...n parameters. I've included an example below using a CTE to populate the initial table.

DECLARE @NumItems int = 100;

DECLARE @minValue int;
DECLARE @maxValue int;
SELECT @minValue = min(id), @maxValue = max(id) from [TABLE];
DECLARE @range int = @maxValue+1 - @minValue;

with cte (n) as (
   select 1 union all
   select n+1 from cte
   where n < @NumItems
)
select cast( @range * rand(cast(newid() as varbinary(100))) + @minValue as int) tp
into #Nt
from cte;

select * from #Nt ntt
inner join [TABLE] i on i.id = ntt.tp;

drop table #Nt;

Use double brackets...

if [[ expression ]]

You must reference Context name before using getResources() in Android.

String user=getApplicationContext().getResources().getString(R.string.muser);

OR

Context mcontext=getApplicationContext();

String user=mcontext.getResources().getString(R.string.muser);

Is there a single declaration that fixes this for Webkit, Gecko, and Blink? No. However, there is a cross-browser solution by specifying multiple width property values that correspond to each layout engine's convention.

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

Trailing commas are allowed in JavaScript, but don't work in IE. Douglas Crockford's versionless JSON spec didn't allow them, and because it was versionless this wasn't supposed to change. The ES5 JSON spec allowed them as an extension, but Crockford's RFC 4627 didn't, and ES5 reverted to disallowing them. Firefox followed suit. Internet Explorer is why we can't have nice things.

another great and easy way is to have a blind modal in your layout and call it if neccessary.

JS

  var remote_modal = function(url) {
    // reset modal body with a spinner or empty content
    spinner = "<div class='text-center'><i class='fa fa-spinner fa-spin fa-5x fa-fw'></i></div>"

    $("#remote-modal .modal-body").html(spinner)
    $("#remote-modal .modal-body").load(url);
    $("#remote-modal").modal("show");
  }

and your HTML

 <div class='modal fade' id='remote-modal'>
    <div class='modal-dialog modal-lg'>
      <div class='modal-content'>
        <div class='modal-body'></div>
        <div class='modal-footer'>
          <button class='btn btn-default'>Close</button>
        </div>
      </div>
    </div>
  </div>
</body>

now you can simply call remote_modal('/my/url.html') and the content gets displayed inside of the modal

just add

$autoload['helper'] = array('url');

in autoload.php in your config file

Just to add to the accepted answer, as all the answers seem to talk about android.graphics.Color only: what if the color I want is defined in res/values/colors.xml?

For example, consider Material Design colors defined in colors.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="md_blue_500">#2196F3</color>
</resources>

(android_material_design_colours.xml is your best friend)

Then use ContextCompat.getColor(getContext(), R.color.md_blue_500) where you would use Color.BLUE, so that:

wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

becomes:

wordtoSpan.setSpan(new ForegroundColorSpan(ContextCompat.getColor(getContext(), R.color.md_blue_500)), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

It's worth trying faulthandler to identify the line or the library that is causing the issue as mentioned here https://stackoverflow.com/a/58825725/2160809 and in the comments by Karuhanga

faulthandler.enable()
// bad code goes here

or

$ python3 -q -X faulthandler

Integer.toBinaryString((byteValue & 0xFF) + 256).substring(1)

FragmentPagerAdapter is the factory of the fragments. To find a fragment based on its position if still in memory use this:

public Fragment findFragmentByPosition(int position) {
    FragmentPagerAdapter fragmentPagerAdapter = getFragmentPagerAdapter();
    return getSupportFragmentManager().findFragmentByTag(
            "android:switcher:" + getViewPager().getId() + ":"
                    + fragmentPagerAdapter.getItemId(position));
}
