Simply put: At each step of your algorithm you can cut the work in half. (Asymptotically equivalent to third, fourth, ...)

The EOF character recognized by the command interpreter on Windows (and MSDOS, and CP/M) is 0x1a (decimal 26, aka Ctrl+Z aka SUB)

It can still be be used today for example to mark the end of a human-readable header in a binary file: if the file begins with "Some description\x1a" the user can dump the file content to the console using the TYPE command and the dump will stop at the EOF character, i.e. print Some description and stop, instead of continuing with the garbage that follows.

I've been using this little cheat for a while now. You might enjoy it. nest the table you want to center in another table:

<table height=100% width=100%>
<td align=center valign=center>

(add your table here)

</td>
</table>

the align and valign put the table exactly in the middle of the screen, no matter what else is going on.

In latest 5.13 there's a difference. You do like always...

font-family: "Font Awesome 5 Free";
content: "\f107";

But there's a difference now... Instead of use font-weight: 500; You are following this:

font-family: "Font Awesome 5 Free";
font-weight: 900;
content: "\f107";

Why is that? I figure out by finding in in .fas class, so you can figure out an updated way by looking into .fas class so you're doing the same as it has to be. Figure out if there's a font-weight and font-family. Here you go guys. That's an update answer for 5.13.

The full modern solution to your problem is purely CSS-based, but note that older browsers won't support it, in which cases you'd need to fallback to solutions such as the others have provided.

So in pure CSS:

-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-o-user-select: none;
user-select: none;

However the mouse cursor will still change to a caret when over the element's text, so you add to that:

cursor: default;

Modern CSS is pretty elegant.

It is mentioned in the .data() documentation

The data- attributes are pulled in the first time the data property is accessed and then are no longer accessed or mutated (all data values are then stored internally in jQuery)

This was also covered on Why don't changes to jQuery $.fn.data() update the corresponding html 5 data-* attributes?

The demo on my original answer below doesn't seem to work any more.

Updated answer

Again, from the .data() documentation

The treatment of attributes with embedded dashes was changed in jQuery 1.6 to conform to the W3C HTML5 specification.

So for <div data-role="page"></div> the following is true $('div').data('role') === 'page'

I'm fairly sure that $('div').data('data-role') worked in the past but that doesn't seem to be the case any more. I've created a better showcase which logs to HTML rather than having to open up the Console and added an additional example of the multi-hyphen to camelCase data- attributes conversion.

Updated demo (2015-07-25)

Also see jQuery Data vs Attr?

HTML

<div id="changeMe" data-key="luke" data-another-key="vader"></div>
<a href="#" id="changeData"></a>
<table id="log">
    <tr><th>Setter</th><th>Getter</th><th>Result of calling getter</th><th>Notes</th></tr>
</table>

JavaScript (jQuery 1.6.2+)

var $changeMe = $('#changeMe');
var $log = $('#log');

var logger;
(logger = function(setter, getter, note) {
    note = note || '';
    eval('$changeMe' + setter);
    var result = eval('$changeMe' + getter);
    $log.append('<tr><td><code>' + setter + '</code></td><td><code>' + getter + '</code></td><td>' + result + '</td><td>' + note + '</td></tr>');
})('', ".data('key')", "Initial value");

$('#changeData').click(function() {
    // set data-key to new value
    logger(".data('key', 'leia')", ".data('key')", "expect leia on jQuery node object but DOM stays as luke");
    // try and set data-key via .attr and get via some methods
    logger(".attr('data-key', 'yoda')", ".data('key')", "expect leia (still) on jQuery object but DOM now yoda");
    logger("", ".attr('key')", "expect undefined (no attr <code>key</code>)");
    logger("", ".attr('data-key')", "expect yoda in DOM and on jQuery object");

    // bonus points
    logger('', ".data('data-key')", "expect undefined (cannot get via this method)");
    logger(".data('anotherKey')", ".data('anotherKey')", "jQuery 1.6+ get multi hyphen <code>data-another-key</code>");
    logger(".data('another-key')", ".data('another-key')", "jQuery < 1.6 get multi hyphen <code>data-another-key</code> (also supported in jQuery 1.6+)");

    return false;
});

$('#changeData').click();

Older demo

Original answer

For this HTML:

<div id="foo" data-helptext="bar"></div>
<a href="#" id="changeData">change data value</a>

and this JavaScript (with jQuery 1.6.2)

console.log($('#foo').data('helptext'));

$('#changeData').click(function() {
    $('#foo').data('helptext', 'Testing 123');
//  $('#foo').attr('data-helptext', 'Testing 123');
    console.log($('#foo').data('data-helptext'));
    return false;
});

See demo

Using the Chrome DevTools Console to inspect the DOM, the $('#foo').data('helptext', 'Testing 123'); does not update the value as seen in the Console but $('#foo').attr('data-helptext', 'Testing 123'); does.

you can still use

String Item = getIntent().getExtras().getString("name");

in the fragment, you just need call getActivity() first:

String Item = getActivity().getIntent().getExtras().getString("name");

This saves you having to write some code.

To add a new file in SVN

svn add file_name
svn commit -m "text about changes..."

To add a new file in a directory in SVN

svn add directory_name/file_name
svn commit -m "text about changes"

To add all new files in a directory with some targets (files) are already versioned (added):

svn add directory_name/*
svn commit -m "text about changes"

I've developed an almost flawless try & catch implementation in bash, that allows you to write code like:

try 
    echo 'Hello'
    false
    echo 'This will not be displayed'

catch 
    echo "Error in $__EXCEPTION_SOURCE__ at line: $__EXCEPTION_LINE__!"

You can even nest the try-catch blocks inside themselves!

try {
    echo 'Hello'

    try {
        echo 'Nested Hello'
        false
        echo 'This will not execute'
    } catch {
        echo "Nested Caught (@ $__EXCEPTION_LINE__)"
    }

    false
    echo 'This will not execute too'

} catch {
    echo "Error in $__EXCEPTION_SOURCE__ at line: $__EXCEPTION_LINE__!"
}

The code is a part of my bash boilerplate/framework. It further extends the idea of try & catch with things like error handling with backtrace and exceptions (plus some other nice features).

Here's the code that's responsible just for try & catch:

set -o pipefail
shopt -s expand_aliases
declare -ig __oo__insideTryCatch=0

# if try-catch is nested, then set +e before so the parent handler doesn't catch us
alias try="[[ \$__oo__insideTryCatch -gt 0 ]] && set +e;
           __oo__insideTryCatch+=1; ( set -e;
           trap \"Exception.Capture \${LINENO}; \" ERR;"
alias catch=" ); Exception.Extract \$? || "

Exception.Capture() {
    local script="${BASH_SOURCE[1]#./}"

    if [[ ! -f /tmp/stored_exception_source ]]; then
        echo "$script" > /tmp/stored_exception_source
    fi
    if [[ ! -f /tmp/stored_exception_line ]]; then
        echo "$1" > /tmp/stored_exception_line
    fi
    return 0
}

Exception.Extract() {
    if [[ $__oo__insideTryCatch -gt 1 ]]
    then
        set -e
    fi

    __oo__insideTryCatch+=-1

    __EXCEPTION_CATCH__=( $(Exception.GetLastException) )

    local retVal=$1
    if [[ $retVal -gt 0 ]]
    then
        # BACKWARDS COMPATIBILE WAY:
        # export __EXCEPTION_SOURCE__="${__EXCEPTION_CATCH__[(${#__EXCEPTION_CATCH__[@]}-1)]}"
        # export __EXCEPTION_LINE__="${__EXCEPTION_CATCH__[(${#__EXCEPTION_CATCH__[@]}-2)]}"
        export __EXCEPTION_SOURCE__="${__EXCEPTION_CATCH__[-1]}"
        export __EXCEPTION_LINE__="${__EXCEPTION_CATCH__[-2]}"
        export __EXCEPTION__="${__EXCEPTION_CATCH__[@]:0:(${#__EXCEPTION_CATCH__[@]} - 2)}"
        return 1 # so that we may continue with a "catch"
    fi
}

Exception.GetLastException() {
    if [[ -f /tmp/stored_exception ]] && [[ -f /tmp/stored_exception_line ]] && [[ -f /tmp/stored_exception_source ]]
    then
        cat /tmp/stored_exception
        cat /tmp/stored_exception_line
        cat /tmp/stored_exception_source
    else
        echo -e " \n${BASH_LINENO[1]}\n${BASH_SOURCE[2]#./}"
    fi

    rm -f /tmp/stored_exception /tmp/stored_exception_line /tmp/stored_exception_source
    return 0
}

I have installed VMWare Workstation. So, It was causing the error.

Services.msc and stopped the 'Workstation' Services.

This has solved my problems.

Thanks

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[]>.

changeDate has been renamed to change.dp so changedate was not working for me

$("#datetimepicker").datetimepicker().on('change.dp', function (e) {
            FillDate(new Date());
    });

also needed to change css class from datepicker to datepicker-input

<div id='datetimepicker' class='datepicker-input input-group controls'>
   <input id='txtStartDate' class='form-control' placeholder='Select datepicker' data-rule-required='true' data-format='MM-DD-YYYY' type='text' />

       <span class='icon-calendar' data-time-icon='icon-time' data-date-icon='icon-calendar'></span>

Date formate also works in capitals like this data-format='MM-DD-YYYY'

it might be helpful for someone it gave me really hard time :)

These posts may be in the wrong order! This is #2 in a series of 3 posts. Sorry.

I've "taken a few liberties" with Lie Ryan's code, implementing a linked list so individual elements of his vector can be accessed via a linked list. This allows access, but admittedly it is time-consuming to access individual elements due to search overhead, i.e. walking down the list until you find the right element. I'll cure this by maintaining an address vector containing subscripts 0 through whatever paired with memory addresses. This is still not as efficient as a plain-and-simple array would be, but at least you don't have to "walk the list" searching for the proper item.

This will delete all rows that had been selected.

This because the input that the user inserts into the JOptionPane is a String and it is stored and returned as a String.

Java cannot convert between strings and number by itself, you have to use specific functions, just use:

int ans = Integer.parseInt(JOptionPane.showInputDialog(...))

One solution is like, If you know the specific lat/lng.

google.maps.event.addListener(map, 'idle', function() {

    map.setCenter(new google.maps.LatLng(latitude, longitude));
    map.setZoom(8);

});

If don't have specific lat/lng

google.maps.event.addListener(map, 'idle', function() {

    map.setCenter(map.getCenter());
    map.setZoom(8);

});

or

google.maps.event.addListener(map, 'idle', function() {

    var bounds = new google.maps.LatLngBounds();
    map.setCenter(bounds.getCenter());
    map.setZoom(8);

});

1. Extract the zip file into a folder, e.g. C:\Program Files\Java\ and it will create a jdk-11 folder (where the bin folder is a direct sub-folder). You may need Administrator privileges to extract the zip file to this location.

2. Set a PATH:

   • Select Control Panel and then System.
   • Click Advanced and then Environment Variables.
   • Add the location of the bin folder of the JDK installation to the PATH variable in System Variables.
   • The following is a typical value for the PATH variable: C:\WINDOWS\system32;C:\WINDOWS;"C:\Program Files\Java\jdk-11\bin"

3. Set JAVA_HOME:

   • Under System Variables, click New.
   • Enter the variable name as JAVA_HOME.
   • Enter the variable value as the installation path of the JDK (without the bin sub-folder).
   • Click OK.
   • Click Apply Changes.
4. Configure the JDK in your IDE (e.g. IntelliJ or Eclipse).

You are set.

To see if it worked, open up the Command Prompt and type java -version and see if it prints your newly installed JDK.

If you want to uninstall - just undo the above steps.

Note: You can also point JAVA_HOME to the folder of your JDK installations and then set the PATH variable to %JAVA_HOME%\bin. So when you want to change the JDK you change only the JAVA_HOME variable and leave PATH as it is.

I'm using mongojs, and i have this example:

db.users.findOne({'_id': db.ObjectId(user_id)  }, function(err, user) {
   if(err == null && user != null){
      user._id.toHexString(); // I convert the objectId Using toHexString function.
   }
})

I hope this help.

underscore.js provides the following method to find out if something is really an object:

_.isObject = function(obj) {
  return obj === Object(obj);
};

UPDATE

Because of a previous bug in V8 and minor micro speed optimization, the method looks as follows since underscore.js 1.7.0 (August 2014):

_.isObject = function(obj) {
  var type = typeof obj;
  return type === 'function' || type === 'object' && !!obj;
};

For most it is a breeze, however like you I had a difficult time installing jq

The best resources I found are: https://stedolan.github.io/jq/download/ and http://macappstore.org/jq/

However neither worked for me. I run python 2 & 3, and use brew in addition to pip, as well as Jupyter. I was only successful after brew uninstall jq then updating brew and rebooting my system

What worked for me was removing all previous installs then pip install jq

Here's a better approach where you don't have to delete/move anything for Android Studio 3.+.

1. Open Android Studio and click cancel/ignore for error prompts on missing SDK for each project.
2. Close all your open projects. You can do this by File > Close Project.
3. After you do step 1 for all projects, the Welcome screen appears.
4. The welcome screen will detect you are missing the SDK and give you options to fix the problem, i.e., install the SDKs for you.

Well when you are writing a c program and want the output log to stay instead of flickering away you only need to import the stdlib.h header file and type "system("PAUSE");" at the place you want the output screen to halt.Look at the example here.The following simple c program prints the product of 5 and 6 i.e 30 to the output window and halts the output window.

#include <stdio.h>
#include <stdlib.h>
int main()
 {
      int a,b,c;
      a=5;b=6;
      c=a*b;
      printf("%d",c);
      system("PAUSE");
      return 0;
 }

Hope this helped.

Apple added a JSON parser and serializer in iOS 5.0 and Mac OS X 10.7. See NSJSONSerialization.

To generate a JSON string from a NSDictionary or NSArray, you do not need to import any third party framework anymore.

Here is how to do it:

NSError *error; 
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionaryOrArrayToOutput 
                                                   options:NSJSONWritingPrettyPrinted // Pass 0 if you don't care about the readability of the generated string
                                                     error:&error];

if (! jsonData) {
    NSLog(@"Got an error: %@", error);
} else {
    NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
}

In addition to the answers above you can pass in command line parameters to the mysqld process for logging options instead of manually editing your conf file. For example, to enable general logging and specifiy a file:

mysqld --general-log --general-log-file=/var/log/mysql.general.log

Confirming other answers above, mysqld --help --verbose gives you the values from the conf file (so running with command line options general-log is FALSE); whereas mysql -se "SHOW VARIABLES" | grep -e log_error -e general_log gives:

general_log     ON
general_log_file        /var/log/mysql.general.log

Use slightly more compact syntax for the error log:

mysqld --general-log --general-log-file=/var/log/mysql.general.log --log-error=/var/log/mysql.error.log

In some scenarios {new: true} is not working. Then you can try this.

{'returnNewDocument':true}

Add a level in your appsettings.json :

{
  "MySettings": {
    "MyArray": [
      "str1",
      "str2",
      "str3"
    ]
  }
}

Create a class representing your section :

public class MySettings
{
     public List<string> MyArray {get; set;}
}

In your application startup class, bind your model an inject it in the DI service :

services.Configure<MySettings>(options => Configuration.GetSection("MySettings").Bind(options));

And in your controller, get your configuration data from the DI service :

public class HomeController : Controller
{
    private readonly List<string> _myArray;

    public HomeController(IOptions<MySettings> mySettings)
    {
        _myArray = mySettings.Value.MyArray;
    }

    public IActionResult Index()
    {
        return Json(_myArray);
    }
}

You can also store your entire configuration model in a property in your controller, if you need all the data :

public class HomeController : Controller
{
    private readonly MySettings _mySettings;

    public HomeController(IOptions<MySettings> mySettings)
    {
        _mySettings = mySettings.Value;
    }

    public IActionResult Index()
    {
        return Json(_mySettings.MyArray);
    }
}

The ASP.NET Core's dependency injection service works just like a charm :)

I used convertPoint method to get point from tableview and pass this point to indexPathForRowAtPoint method to get indexPath

 @IBAction func newsButtonAction(sender: UIButton) {
        let buttonPosition = sender.convertPoint(CGPointZero, toView: self.newsTableView)
        let indexPath = self.newsTableView.indexPathForRowAtPoint(buttonPosition)
        if indexPath != nil {
            if indexPath?.row == 1{
                self.performSegueWithIdentifier("alertViewController", sender: self);
            }   
        }
    }

You can use the following SQL to compare both date and time -

Select * From temp where mydate > STR_TO_DATE('2009-06-29 04:00:44', '%Y-%m-%d %H:%i:%s');

Attached mysql output when I used same SQL on same kind of table and field that you mentioned in the problem-

It should work perfect.

Use Iterator.remove().

ActiveCell.Offset(0, -1).Select
Selection.End(xlDown).Select
ActiveCell.Offset(0, 1).Select
Range(Selection, Selection.End(xlUp)).Select
Selection.FillDown

If you have initialized the form like this

form = CustomForm()

then the correct way as of Jan 2019, is to use .initial to replace the data. This will replace the data in the intial dict that goes along with the form. It also works if you have initialized using some instance such as form = CustomForm(instance=instance)

To replace data in the form, you need to

form.initial['Email'] = GetEmailString()

Generalizing this it would be,

form.initial['field_name'] = new_value

You can try to use:

where(date: p[:date]..Float::INFINITY)

equivalent in sql

WHERE (`date` >= p[:date])

The result is:

Note.where(user_id: current_user.id, notetype: p[:note_type], date: p[:date]..Float::INFINITY).order(:fecha, :created_at)

And I have changed too

order('date ASC, created_at ASC')

For

order(:fecha, :created_at)

Besides installing the required packages, I also needed to manually add PostgreSQL bin directory to PATH.
$vi ~/.bash_profile
Add PATH=/usr/pgsql-9.2/bin:$PATH before export PATH.
$source ~/.bash_profile
$pip install psycopg2

Just found sys.executable - the full path to the current Python executable, which can be used to run the script (instead of relying on the shbang, which obviously doesn't work on Windows)

import sys
import subprocess

theproc = subprocess.Popen([sys.executable, "myscript.py"])
theproc.communicate()

I had this problem in a DataFrame (df) created from an Excel-sheet with several internal header rows.

After cleaning out the internal header rows from df, the columns' values were of "non-null object" type (DataFrame.info()).

This code converted all numerical values of multiple columns to int64 and float64 in one go:

for i in range(0, len(df.columns)):
    df.iloc[:,i] = pd.to_numeric(df.iloc[:,i], errors='ignore')
    # errors='ignore' lets strings remain as 'non-null objects'

  <script type="text/javascript">
  jQuery(document).ready(function(){
         setTimeout(PopUp(),5000); // invoke Popup function after 5 seconds 
  });
   </script>

Above solution works best if multiple matching sub documents are required. $elemMatch also comes in very use if single matching sub document is required as output

db.test.find({list: {$elemMatch: {a: 1}}}, {'list.$': 1})

Result:

{
  "_id": ObjectId("..."),
  "list": [{a: 1}]
}

The problem is the linker is looking for libmagic.so but you only have libmagic.so.1

A quick hack is to symlink libmagic.so.1 to libmagic.so

This is the first post on google so I thought I'd post different ways that are available and how they compare. Unfortunately I can't figure out how to create a table here, so it's an image. The code for each is below the image using fully qualified names.

There are multiple options available to reuse the existing powerful libraries that are standards based.

If you happen to use D3 in your project, then you can simply invoke:

    d3.csv.format or d3.csv.formatRows functions to convert an array of objects into csv string.

    d3.csv.formatRows gives you greater control over which properties are converted to csv.

    Please refer to d3.csv.format and d3.csv.formatRows wiki pages.

There are other libraries available too like jquery-csv, PapaParse. Papa Parse has no dependencies - not even jQuery.

For jquery based plugins, please check this.

SSIS doesn't implicitly convert data types, so you need to do it explicitly. The Excel connection manager can only handle a few data types and it tries to make a best guess based on the first few rows of the file. This is fully documented in the SSIS documentation.

You have several options:

• Change your destination data type to float
• Load to a 'staging' table with data type float using the Import Wizard and then INSERT into the real destination table using CAST or CONVERT to convert the data
• Create an SSIS package and use the Data Conversion transformation to convert the data

You might also want to note the comments in the Import Wizard documentation about data type mappings.

Add set clipboard=unnamed to your .vimrc. So it will use the clipboard register '*' instead of the unnamed register for all yank, delete, change and put operations (note it does not only affect the mouse).

The behavior of register '*' depends on your platform and how your vim has been compiled (or if you use neovim).

If it does not work, you can try with set clipboard=unnamedplus, but this option only makes sense on X11 systems (and gvim therefore).

Try sudo npm uninstall cordova -g to uninstall it globally and then just npm install cordova without the -g flag after cding to the local app directory

I use this code with some little personal variations in my AppDelegate class

    {
        // filter nav controller
        vc = [AppDelegate findChildThatIsNotNavController:vc];
        // filter tab controller
        if ([vc isKindOfClass:[UITabBarController class]]) {
            UITabBarController *tbc = ((UITabBarController*)vc);
            if ([tbc viewControllers].count > 0) {
                vc = [tbc viewControllers][tbc.selectedIndex];
                // filter nav controller again
                vc = [AppDelegate findChildThatIsNotNavController:vc];
            }
        }
    }
    return vc;
}
/**

+(UIViewController*)findChildThatIsNotNavController:(UIViewController*)vc
{
    if ([vc isKindOfClass:[UINavigationController class]]) {
        if (((UINavigationController *)vc).viewControllers.count > 0) {
            vc = [((UINavigationController *)vc).viewControllers objectAtIndex:0];
        }
    }
    return vc;
}

Use ./gradlew instead of gradle to resolve this issue.

Update: This solution works and just a call to 'FB.logout()' doesn't work because browser wants a user interaction to actually call this function, so that it knows - it is a user not a script.

<a href="#" onclick="FB.logout();">Logout</a> 

The following will list the methods that the User class has that the base Object class does not have...

>> User.methods - Object.methods
=> ["field_types", "maximum", "create!", "active_connections", "to_dropdown",
    "content_columns", "su_pw?", "default_timezone", "encode_quoted_value", 
    "reloadable?", "update", "reset_sequence_name", "default_timezone=", 
    "validate_find_options", "find_on_conditions_without_deprecation", 
    "validates_size_of", "execute_simple_calculation", "attr_protected", 
    "reflections", "table_name_prefix", ...

Note that methods is a method for Classes and for Class instances.

Here's the methods that my User class has that are not in the ActiveRecord base class:

>> User.methods - ActiveRecord::Base.methods
=> ["field_types", "su_pw?", "set_login_attr", "create_user_and_conf_user", 
    "original_table_name", "field_type", "authenticate", "set_default_order",
    "id_name?", "id_name_column", "original_locking_column", "default_order",
    "subclass_associations",  ... 
# I ran the statements in the console.

Note that the methods created as a result of the (many) has_many relationships defined in the User class are not in the results of the methods call.

Added Note that :has_many does not add methods directly. Instead, the ActiveRecord machinery uses the Ruby method_missing and responds_to techniques to handle method calls on the fly. As a result, the methods are not listed in the methods method result.

I was getting the error "The module may compatible with this version of windows" for both version of RegSvr32 (32 bit and 64 bit). I was trying to register a DLL that was built for XP (32 bit) in Server 2008 R2 (x64) and none of the Regsr32 resolutions worked for me. However, registering the assembly in the appropriate .Net worked perfect for me. C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm.exe

Edited answer.

After having some experience with both these APIs, I would say that there are 2 blocking level features which renders mysqli unusable with native prepared statements.
They were already mentioned in 2 excellent (yet way underrated) answers:

1. Binding values to arbitrary number of placeholders
2. Returning data as a mere array

(both also mentioned in this answer)

For some reason mysqli failed with both.
Nowadays it got some improvement for the second one (get_result), but it works only on mysqlnd installations, means you can't rely on this function in your scripts.

Yet it doesn't have bind-by-value even to this day.

So, there is only one choice: PDO

All the other reasons, such as

• named placeholders (this syntax sugar is way overrated)
• different databases support (nobody actually ever used it)
• fetch into object (just useless syntax sugar)
• speed difference (there is none)

aren't of any significant importance.

At the same time both these APIs lacks some real important features, like

• identifier placeholder
• placeholder for the complex data types to make dynamical binding less toilsome
• shorter application code.

So, to cover the real life needs, one have to create their own abstraction library, based on one of these APIs, implementing manually parsed placeholders. In this case I'd prefer mysqli, for it has lesser level of abstraction.

If you put it in a PictureBox control, it should just work

SELECT COUNT(*) FROM information_schema.tables

Yes you can solve this error by changing the port number of glassfish because the WAMP SERVER or ORACLE database software uses a port number 8080, so there is a conflict of port number.

1)open a path like C:\GlassFish_Server\glassfish\domains\domain1\config\domain.xml.

2)find out the 8080 port number with the help of ctrl+F. You will get the following code...

<network-listener protocol="http-listener-1" port="8080" name="http-listener-1" thread-pool="http-thread-pool" transport="tcp">

3) Change that port number from 8080 to 9090 or 1234 or whatever you like..

4) Save it. Open a Netbeans IDE goto the glassfish server .

5) Right click on the server -> select refresh option.

6) to check the port no. which is given by u just right click on the server-> property.

7) Start the Glassfish server . Yehhh the error is gone...

Answer update of 13-October-2018

To initiate a google-chrome-headless browsing context using Selenium driven ChromeDriver now you can just set the --headless property to true through an instance of Options() class as follows:

• Effective code block:

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  options = Options()
  options.headless = True
  driver = webdriver.Chrome(options=options, executable_path=r'C:\path\to\chromedriver.exe')
  driver.get("http://google.com/")
  print ("Headless Chrome Initialized")
  driver.quit()
  

Answer update of 23-April-2018

Invoking google-chrome in headless mode programmatically have become much easier with the availability of the method set_headless(headless=True) as follows :

• Documentation :

  set_headless(headless=True)
      Sets the headless argument
  
      Args:
          headless: boolean value indicating to set the headless option
  

• Sample Code :

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  options = Options()
  options.set_headless(headless=True)
  driver = webdriver.Chrome(options=options, executable_path=r'C:\path\to\chromedriver.exe')
  driver.get("http://google.com/")
  print ("Headless Chrome Initialized")
  driver.quit()
  

Note : --disable-gpu argument is implemented internally.

Original Answer of Mar 30 '2018

While working with Selenium Client 3.11.x, ChromeDriver v2.38 and Google Chrome v65.0.3325.181 in Headless mode you have to consider the following points :

• You need to add the argument --headless to invoke Chrome in headless mode.

• For Windows OS systems you need to add the argument --disable-gpu

• As per Headless: make --disable-gpu flag unnecessary --disable-gpu flag is not required on Linux Systems and MacOS.

• As per SwiftShader fails an assert on Windows in headless mode --disable-gpu flag will become unnecessary on Windows Systems too.

• Argument start-maximized is required for a maximized Viewport.

• Here is the link to details about Viewport.

• You may require to add the argument --no-sandbox to bypass the OS security model.

• Effective windows code block :

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  options = Options()
  options.add_argument("--headless") # Runs Chrome in headless mode.
  options.add_argument('--no-sandbox') # Bypass OS security model
  options.add_argument('--disable-gpu')  # applicable to windows os only
  options.add_argument('start-maximized') # 
  options.add_argument('disable-infobars')
  options.add_argument("--disable-extensions")
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\path\to\chromedriver.exe')
  driver.get("http://google.com/")
  print ("Headless Chrome Initialized on Windows OS")
  

• Effective linux code block :

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  options = Options()
  options.add_argument("--headless") # Runs Chrome in headless mode.
  options.add_argument('--no-sandbox') # # Bypass OS security model
  options.add_argument('start-maximized')
  options.add_argument('disable-infobars')
  options.add_argument("--disable-extensions")
  driver = webdriver.Chrome(chrome_options=options, executable_path='/path/to/chromedriver')
  driver.get("http://google.com/")
  print ("Headless Chrome Initialized on Linux OS")

Here is the link to the Sandbox story.

I had the same problem. I decided in a very unexpected way. Just opened the command line as an administrator. And then typed:

pip install numpy

you can use valign="top" on the td tag it is working perfectly for me.

Configuring a button (or any widget) in Tkinter is done by calling a configure method "config"

To change the size of a button called button1 you simple call

button1.config( height = WHATEVER, width = WHATEVER2 )

If you know what size you want at initialization these options can be added to the constructor.

button1 = Button(self, text = "Send", command = self.response1, height = 100, width = 100) 

Just want to open the app through browser? You can achieve it using below code:

HTML:

<a href="intent:#Intent;action=packageName;category=android.intent.category.DEFAULT;category=android.intent.category.BROWSABLE;end">Click here</a>

Manifest:

<intent-filter>
      <action android:name="packageName" />
      <category android:name="android.intent.category.DEFAULT" />
      <category android:name="android.intent.category.BROWSABLE" />
</intent-filter>

This intent filter should be in Launcher Activity.

If you want to pass the data on click of browser link, just refer this link.

If you want to create and submit your form from Javascript as is in your question and you want to create popup window with custom features I propose this solution (I put comments above the lines i added):

var form = document.createElement("form");
form.setAttribute("method", "post");
form.setAttribute("action", "test.jsp");

// setting form target to a window named 'formresult'
form.setAttribute("target", "formresult");

var hiddenField = document.createElement("input");              
hiddenField.setAttribute("name", "id");
hiddenField.setAttribute("value", "bob");
form.appendChild(hiddenField);
document.body.appendChild(form);

// creating the 'formresult' window with custom features prior to submitting the form
window.open('test.html', 'formresult', 'scrollbars=no,menubar=no,height=600,width=800,resizable=yes,toolbar=no,status=no');

form.submit();

You may also use --keyid-format switch to show short or long key ID:

$ gpg2 -n --with-fingerprint --keyid-format=short --show-keys <filename>

which outputs like this (example from PostgreSQL CentOS repo key):

pub   dsa1024/442DF0F8 2008-01-08 [SCA]                                                                       ¦
      Key fingerprint = 68C9 E2B9 1A37 D136 FE74  D176 1F16 D2E1 442D F0F8                                    ¦              honor-keyserver-url

Just found this simple method to make HttpResponse content as a json

import json

request = RequestFactory() # ignore this, this just like your request object

response = MyView.as_view()(request) # got response as HttpResponse object

response.render() # call this so we could call response.content after

json_response = json.loads(response.content.decode('utf-8'))

print(json_response) # {"your_json_key": "your json value"}

You can use select into inside of a PLSQL block such as below.

Declare
  l_variable assignment%rowtype
begin
  select *
  into l_variable
  from assignment;
exception
  when no_data_found then
    dbms_output.put_line('No record avialable')
  when too_many_rows then
   dbms_output.put_line('Too many rows')
end;

This code will only work when there is exactly 1 row in assignment. Usually you will use this kind of code to select a specific row identified by a key number.

Declare
  l_variable assignment%rowtype
begin
  select *
  into l_variable
  from assignment
  where ID=<my id number>;
exception
  when no_data_found then
    dbms_output.put_line('No record avialable')
  when too_many_rows then
   dbms_output.put_line('Too many rows')
end;

for k, m in self.materials.items():

An easy way to pass several arrays as parameter is to use a character-separated string. You can call your script like this:

./myScript.sh "value1;value2;value3" "somethingElse" "value4;value5" "anotherOne"

Then, you can extract it in your code like this:

myArray=$1
IFS=';' read -a myArray <<< "$myArray"

myOtherArray=$3
IFS=';' read -a myOtherArray <<< "$myOtherArray"

This way, you can actually pass multiple arrays as parameters and it doesn't have to be the last parameters.

Try this code

SELECT CONVERT(varchar(max), CAST(1000.2324422 AS decimal(11,2)))

result:1000.23

here decimal(11,2):11-total digits count(without point),2-for two digits after decimal point

The 'ours' in Git is referring to the original working branch which has authoritative/canonical part of git history.

The 'theirs' refers to the version that holds the work in order to be rebased (changes to be replayed onto the current branch).

This may appear to be swapped to people who are not aware that doing rebasing (e.g. git rebase) is actually taking your work on hold (which is theirs) in order to replay onto the canonical/main history which is ours, because we're rebasing our changes as third-party work.

The documentation for git-checkout was further clarified in Git >=2.5.1 as per f303016 commit:

--ours --theirs

When checking out paths from the index, check out stage #2 ('ours') or #3 ('theirs') for unmerged paths.

Note that during git rebase and git pull --rebase, 'ours' and 'theirs' may appear swapped; --ours gives the version from the branch the changes are rebased onto, while --theirs gives the version from the branch that holds your work that is being rebased.

This is because rebase is used in a workflow that treats the history at the remote as the shared canonical one, and treats the work done on the branch you are rebasing as the third-party work to be integrated, and you are temporarily assuming the role of the keeper of the canonical history during the rebase. As the keeper of the canonical history, you need to view the history from the remote as ours (i.e. "our shared canonical history"), while what you did on your side branch as theirs (i.e. "one contributor's work on top of it").

For git-merge it's explain in the following way:

ours

This option forces conflicting hunks to be auto-resolved cleanly by favoring our version. Changes from the other tree that do not conflict with our side are reflected to the merge result. For a binary file, the entire contents are taken from our side.

This should not be confused with the ours merge strategy, which does not even look at what the other tree contains at all. It discards everything the other tree did, declaring our history contains all that happened in it.

theirs

This is the opposite of ours.

Further more, here is explained how to use them:

The merge mechanism (git merge and git pull commands) allows the backend merge strategies to be chosen with -s option. Some strategies can also take their own options, which can be passed by giving -X<option> arguments to git merge and/or git pull.

So sometimes it can be confusing, for example:

• git pull origin master where -Xours is our local, -Xtheirs is theirs (remote) branch
• git pull origin master -r where -Xours is theirs (remote), -Xtheirs is ours

So the 2nd example is opposite to the 1st one, because we're rebasing our branch on top of the remote one, so our starting point is remote one, and our changes are treated as external.

Similar for git merge strategies (-X ours and -X theirs).

You can have them both, just take off the "CURRENT_TIMESTAMP" flag on the created field. Whenever you create a new record in the table, just use "NOW()" for a value.

Or.

On the contrary, remove the 'ON UPDATE CURRENT_TIMESTAMP' flag and send the NOW() for that field. That way actually makes more sense.

Using unique():

dat <- data.frame(id=c(1,1,3),id2=c(1,1,4),somevalue=c("x","y","z"))    
dat[row.names(unique(dat[,c("id", "id2")])),]

%cd% will give you the path of the directory from where the script is running.

Just run:

echo %cd%

Another way to do this by writing less code.

app.use(express.static('public'));

app.get('/', function(req, res) {
   res.sendFile('index.html');
});

You can set events on a combination of key and mouse events, and onblur as well, to be sure. In that event, store the value of the input. In the next call, compare the current value with the lastly stored value. Only do your magic if it has actually changed.

To do this in a more or less clean way:

You can associate data with a DOM element (lookup api.jquery.com/jQuery.data ) So you can write a generic set of event handlers that are assigned to all elements in the form. Each event can pass the element it was triggered by to one generic function. That one function can add the old value to the data of the element. That way, you should be able to implement this as a generic piece of code that works on your whole form and every form you'll write from now on. :) And it will probably take no more than about 20 lines of code, I guess.

An example is in this fiddle: http://jsfiddle.net/zeEwX/

I'd the same issue and solved it by inserting an empty input before the datepicker, that steals the focus every time the dialog is opened. This input is hidden on every opening of the dialog and shown again on closing.

I would rather use the Date valueOf method instead of === or !==

Seems like === is comparing internal Object's references and nothing concerning date.

Straight forward simple way to copy any generic list :

List<whatever> originalCopy=new List<whatever>();//create new list
originalCopy.AddRange(original);//perform copy of original list

Why don't you just stash the vbscript in a batch/vbscript file hybrid. Name the batch hybrid Converter.bat and you can execute it directly as Converter from the cmd line. Sure you can default ALL scripts to run from Cscript or Wscript, but if you want to execute your vbs as a windows script rather than a console script, this could cause some confusion later on. So just set your code to a batch file and run it directly.

Check the answer -> Here

And here is an example:

Converter.bat

::' VBS/Batch Hybrid
::' --- Batch portion ---------
rem^ &@echo off
rem^ &call :'sub
rem^ &exit /b

:'sub
rem^ &echo begin batch
rem^ &cscript //nologo //e:vbscript "%~f0"
rem^ &echo end batch
rem^ &exit /b

'----- VBS portion -----
Dim tester
tester = "Convert data here"
Msgbox tester

Other solution is to use Js to make it positive (min option can be disabled and is not valid when the user types smth) The negative if is not necessary and on('keydown') event can also be used!

let $numberInput =  $('#whatEverId');
$numberInput.on('change', function(){
    let numberInputText = $numberInput.val();
    if(numberInputText.includes('-')){
        $numberInput.val(Math.abs($numberInput.val()));
    }
});

If you want to do that why not go with a while, for ease of mind? :P No, but seriously I didn't know that and seems kinda nice so thanks, nice to know!

You can simply use the reset button type.

<input type="text" />
<input type="reset" />

jsfiddle

Edit: Remember that, the reset button, reset the form for the original values, so, if the field has some value set on the field <input type="text" value="Name" /> after press reset the field will reset the value inserted by user and come back with the word "name" in this example.

Reference: http://api.jquery.com/reset-selector/

You can proceed in this way. It must work for you as well!

Step 1:

virtualenv venv 
source venv/bin/activate

Step 2:

sudo python3 -m pip install opencv-python==3.4.2.16 
sudo python3 -m pip install opencv-contrib-python==3.4.2.16

Step 3:

import cv2
sift = cv2.xfeatures2d.SIFT_create()

Don't use cv2.SIFT() . It will raise an exception.

I've found that a good solution to this type of question is:

:%!sed ...

(or perl if you prefer). IOW, rather than learning vim's regex peculiarities, use a tool you already know. Using perl would make the ? modifier work to ungreedy the match.

Please try the following solution:

<span style='font-family:Arial;'>&#8377;</span>

This will be displayed as : ₹

If you just want to check the type, you can use jQuery's .is() function,

Like in my case I used below,

if($("#id").is("select")) {
 alert('Select'); 
else if($("#id").is("input")) {
 alert("input");
}

BeanUtils will only copy public fields and is a bit slow. Instead go with getter and setter methods.

public Object loadData (RideHotelsService object_a) throws Exception{

        Method[] gettersAndSetters = object_a.getClass().getMethods();

        for (int i = 0; i < gettersAndSetters.length; i++) {
                String methodName = gettersAndSetters[i].getName();
                try{
                  if(methodName.startsWith("get")){
                     this.getClass().getMethod(methodName.replaceFirst("get", "set") , gettersAndSetters[i].getReturnType() ).invoke(this, gettersAndSetters[i].invoke(object_a, null));
                        }else if(methodName.startsWith("is") ){
                            this.getClass().getMethod(methodName.replaceFirst("is", "set") ,  gettersAndSetters[i].getReturnType()  ).invoke(this, gettersAndSetters[i].invoke(object_a, null));
                        }

                }catch (NoSuchMethodException e) {
                    // TODO: handle exception
                }catch (IllegalArgumentException e) {
                    // TODO: handle exception
                }

        }

        return null;
    }

npm run build OR npm run-script build

{
  "name": "build",
  "version": "1.0.0",
  "scripts": {

You're better off looking at argparse for argument parsing.

http://docs.python.org/dev/library/argparse.html

Just makes it easy, no need to do the heavy lifting yourself.

UPDATE: I have created a video on sending multipart/form-data requests to explain this better.

Actually, Postman can do this. Here is a screenshot

Newer version : Screenshot captured from postman chrome extension

Another version

Older version

Make sure you check the comment from @maxkoryukov

Be careful with explicit Content-Type header. Better - do not set it's value, the Postman is smart enough to fill this header for you. BUT, if you want to set the Content-Type: multipart/form-data - do not forget about boundary field.

If all you want to do is run your main class (without compiling the .java files on which the main class doesn't depend), then you can do the following:

cd <root-package-directory>
javac <complete-path-to-main-class>

or

javac -cp <root-package-directory> <complete-path-to-main-class>

javac would automatically resolve all the dependencies and compile all the dependencies as well.

import re
s = raw_input('Type a word: ')
slower=''.join(re.findall(r'[a-z]',s))
supper=''.join(re.findall(r'[A-Z]',s))
print slower, supper

Prints:

Type a word: A Title of a Book
itleofaook ATB

Or you can use a list comprehension / generator expression:

slower=''.join(c for c in s if c.islower())
supper=''.join(c for c in s if c.isupper())
print slower, supper

Prints:

Type a word: A Title of a Book
itleofaook ATB

To do this in t-sql, you can use the following system stored procedures to schedule a daily job. This example schedules daily at 1:00 AM. See Microsoft help for details on syntax of the individual stored procedures and valid range of parameters.

DECLARE @job_name NVARCHAR(128), @description NVARCHAR(512), @owner_login_name NVARCHAR(128), @database_name NVARCHAR(128);

SET @job_name = N'Some Title';
SET @description = N'Periodically do something';
SET @owner_login_name = N'login';
SET @database_name = N'Database_Name';

-- Delete job if it already exists:
IF EXISTS(SELECT job_id FROM msdb.dbo.sysjobs WHERE (name = @job_name))
BEGIN
    EXEC msdb.dbo.sp_delete_job
        @job_name = @job_name;
END

    @active_end_time=235959; --HHMMSS

Another way is adding a transparent button to the view

UIButton *b = [UIButton buttonWithType:UIButtonTypeCustom];
b.frame = CGRectMake(0, 0, headerView.width, headerView.height);
[headerView addSubview:b];
[b addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchDown];

And then, handle click:

- (void)buttonClicked:(id)sender
{}

The first line tells the shell that if you execute the script directly (./run.sh; as opposed to /bin/sh run.sh), it should use that program (/bin/sh in this case) to interpret it.

You can also use it to pass arguments, commonly -e (exit on error), or use other programs (/bin/awk, /usr/bin/perl, etc).

Thanks for all help at this issue. I'll post here my solution:

  FUNCTION GetExchangeRate RETURN X.exch_tbl PIPELINED;

Please review.

This can happen if there are too many open connections.

Try increasing the maxClientCnxns setting.

From documentation:

maxClientCnxns (No Java system property)

Limits the number of concurrent connections (at the socket level) that a single client, identified by IP address, may make to a single member of the ZooKeeper ensemble. This is used to prevent certain classes of DoS attacks, including file descriptor exhaustion. Setting this to 0 or omitting it entirely removes the limit on concurrent connections.

You can edit settings in the config file. Most likely it can be found at /etc/zookeeper/conf/zoo.cfg.

In modern ZooKeeper versions default value is 60. You can increase it by adding the maxClientCnxns=4096 line to the end of the config file.

There's a workaround for those who want to use Chrome. This extension allows you to request any site with AJAX from any source, since it adds 'Access-Control-Allow-Origin: *' header to the response.

As an alternative, you can add this argument to your Chrome launcher: --disable-web-security. Note that I'd only use this for development purposes, not for normal "web surfing". For reference see Run Chromium with Flags.

As a final note, by installing the extension mentioned on the first paragraph, you can easily enable/disable CORS.

clone() creates a shallow copy. Which means the elements will not be cloned. (What if they didn't implement Cloneable?)

You may want to use Arrays.copyOf(..) for copying arrays instead of clone() (though cloning is fine for arrays, unlike for anything else)

If you want deep cloning, check this answer

A little example to illustrate the shallowness of clone() even if the elements are Cloneable:

ArrayList[] array = new ArrayList[] {new ArrayList(), new ArrayList()};
ArrayList[] clone = array.clone();
for (int i = 0; i < clone.length; i ++) {
    System.out.println(System.identityHashCode(array[i]));
    System.out.println(System.identityHashCode(clone[i]));
    System.out.println(System.identityHashCode(array[i].clone()));
    System.out.println("-----");
}

Prints:

4384790  
4384790
9634993

1641745  
1641745

With the use of concat:

In [128]: df
Out[128]: 
   col_1  col_2
0      0      4
1      1      5
2      2      6
3      3      7

In [129]: pd.concat([df, pd.DataFrame(columns = [ 'column_new_1', 'column_new_2','column_new_3'])])
Out[129]: 
   col_1  col_2 column_new_1 column_new_2 column_new_3

3    3.0    7.0          NaN          NaN          NaN

Not very sure of what you wanted to do with [np.nan, 'dogs',3]. Maybe now set them as default values?

In [142]: df1 = pd.concat([df, pd.DataFrame(columns = [ 'column_new_1', 'column_new_2','column_new_3'])])
In [143]: df1[[ 'column_new_1', 'column_new_2','column_new_3']] = [np.nan, 'dogs', 3]

This might help:

select * from tbl where col like '[ABC-XYZ-PQR]%'

I've used this in SQL Server 2005 and it worked.

If you're looking for a quick way to do this, for example debugging, you can simply concatenate an empty string on to the boolean:

System.out.println(b+"");

However, I strongly recommend using another method for production usage. This is a simple quick solution which is useful for debugging.

vector<int> v1 = {1, 2, 3, 4, 5};
vector<int> v2 = {11, 12, 13, 14, 15};
copy(v2.begin(), v2.end(), back_inserter(v1));

What about

import operator

auths = Author.objects.order_by('-score')[:30]
ordered = sorted(auths, key=operator.attrgetter('last_name'))

In Django 1.4 and newer you can order by providing multiple fields.
Reference: https://docs.djangoproject.com/en/dev/ref/models/querysets/#order-by

order_by(*fields)

By default, results returned by a QuerySet are ordered by the ordering tuple given by the ordering option in the model’s Meta. You can override this on a per-QuerySet basis by using the order_by method.

Example:

ordered_authors = Author.objects.order_by('-score', 'last_name')[:30]

The result above will be ordered by score descending, then by last_name ascending. The negative sign in front of "-score" indicates descending order. Ascending order is implied.

The first approach to take is to modify your web.config using the <location> configuration tag, and <allow users="?"/> to allow anonymous or <allow users="*"/> for all:

<configuration>
   <location path="Path/To/Public/Folder">
      <system.web>
         <authorization>
            <allow users="?"/>
         </authorization>
      </system.web>
   </location>
</configuration>

If that approach doesn't work then you can take the following approach which requires making a small modification to the IIS applicationHost.config.

First, change the anonymousAuthentication section's overrideModeDefault from "Deny" to "Allow" in C:\Windows\System32\inetsrv\config\applicationHost.config:

<section name="anonymousAuthentication" overrideModeDefault="Allow" />

overrideMode is a security feature of IIS. If override is disallowed at the system level in applicationHost.config then there is nothing you can do in web.config to enable it. If you don't have this level of access on your target system you have to take up that discussion with your hosting provider or system administrator.

Second, after setting overrideModeDefault="Allow" then you can put the following in your web.config:

<location path="Path/To/Public/Folder">
  <system.webServer>
    <security>
      <authentication>
        <anonymousAuthentication enabled="true" />
      </authentication>
    </security>
  </system.webServer>
</location>

The official mongo image has merged a PR to include the functionality to databases and admin users at startup.

The database initialisation will run scripts in /docker-entrypoint-initdb.d/ when there is nothing populated in the /data/db directory.

Database Initialisation

The mongo container image provides the /docker-entrypoint-initdb.d/ path to deploy custom .js or .sh setup scripts that will be run once on database initialisation. .js scripts will be run against test by default or MONGO_INITDB_DATABASE if defined in the environment.

COPY mysetup.sh /docker-entrypoint-initdb.d/

or

COPY mysetup.js /docker-entrypoint-initdb.d/

A simple initialisation mongo shell javascript file that demonstrates setting up the container collection with data, logging and how to exit with an error (for result checking).

let error = true

let res = [
  db.container.drop(),
  db.container.createIndex({ myfield: 1 }, { unique: true }),
  db.container.createIndex({ thatfield: 1 }),
  db.container.createIndex({ thatfield: 1 }),
  db.container.insert({ myfield: 'hello', thatfield: 'testing' }),
  db.container.insert({ myfield: 'hello2', thatfield: 'testing' }),
  db.container.insert({ myfield: 'hello3', thatfield: 'testing' }),
  db.container.insert({ myfield: 'hello3', thatfield: 'testing' })
]

printjson(res)

if (error) {
  print('Error, exiting')
  quit(1)
}

Admin User Setup

The environment variables to control "root" user setup are

• MONGO_INITDB_ROOT_USERNAME
• MONGO_INITDB_ROOT_PASSWORD

Example

docker run -d \
  -e MONGO_INITDB_ROOT_USERNAME=admin \
  -e MONGO_INITDB_ROOT_PASSWORD=password \
  mongod

or Dockerfile

FROM docker.io/mongo
ENV MONGO_INITDB_ROOT_USERNAME admin
ENV MONGO_INITDB_ROOT_PASSWORD password

You don't need to use --auth on the command line as the docker entrypoint.sh script adds this in when it detects the environment variables exist.

We find ourselves in a universe which appears to progress along a dimension we call "time". We don't really understand what time is, but we have developed abstractions and vocabulary that let us reason and talk about it: "past", "present", "future", "before", "after".

The computer systems we build--more and more--have time as an important dimension. Certain things are set up to happen in the future. Then other things need to happen after those first things eventually occur. This is the basic notion called "asynchronicity". In our increasingly networked world, the most common case of asynchronicity is waiting for some remote system to respond to some request.

Consider an example. You call the milkman and order some milk. When it comes, you want to put it in your coffee. You can't put the milk in your coffee right now, because it is not here yet. You have to wait for it to come before putting it in your coffee. In other words, the following won't work:

var milk = order_milk();
put_in_coffee(milk);

Because JS has no way to know that it needs to wait for order_milk to finish before it executes put_in_coffee. In other words, it does not know that order_milk is asynchronous--is something that is not going to result in milk until some future time. JS, and other declarative languages execute one statement after another without waiting.

The classic JS approach to this problem, taking advantage of the fact that JS supports functions as first-class objects which can be passed around, is to pass a function as a parameter to the asynchronous request, which it will then invoke when it has completed its task sometime in the future. That is the "callback" approach. It looks like this:

order_milk(put_in_coffee);

order_milk kicks off, orders the milk, then, when and only when it arrives, it invokes put_in_coffee.

The problem with this callback approach is that it pollutes the normal semantics of a function reporting its result with return; instead, functions must not reports their results by calling a callback given as a parameter. Also, this approach can rapidly become unwieldy when dealing with longer sequences of events. For example, let's say that I want to wait for the milk to be put in the coffee, and then and only then perform a third step, namely drinking the coffee. I end up needing to write something like this:

order_milk(function(milk) { put_in_coffee(milk, drink_coffee); }

where I am passing to put_in_coffee both the milk to put in it, and also the action (drink_coffee) to execute once the milk has been put in. Such code becomes hard to write, and read, and debug.

In this case, we could rewrite the code in the question as:

var answer;
$.ajax('/foo.json') . done(function(response) {
  callback(response.data);
});

function callback(data) {
  console.log(data);
}

Enter promises

This was the motivation for the notion of a "promise", which is a particular type of value which represents a future or asynchronous outcome of some sort. It can represent something that already happened, or that is going to happen in the future, or might never happen at all. Promises have a single method, named then, to which you pass an action to be executed when the outcome the promise represents has been realized.

In the case of our milk and coffee, we design order_milk to return a promise for the milk arriving, then specify put_in_coffee as a then action, as follows:

order_milk() . then(put_in_coffee)

One advantage of this is that we can string these together to create sequences of future occurrences ("chaining"):

order_milk() . then(put_in_coffee) . then(drink_coffee)

Let's apply promises to your particular problem. We will wrap our request logic inside a function, which returns a promise:

function get_data() {
  return $.ajax('/foo.json');
}

Actually, all we've done is added a return to the call to $.ajax. This works because jQuery's $.ajax already returns a kind of promise-like thing. (In practice, without getting into details, we would prefer to wrap this call so as for return a real promise, or use some alternative to $.ajax that does so.) Now, if we want to load the file and wait for it to finish and then do something, we can simply say

get_data() . then(do_something)

for instance,

get_data() . 
  then(function(data) { console.log(data); });

When using promises, we end up passing lots of functions into then, so it's often helpful to use the more compact ES6-style arrow functions:

get_data() . 
  then(data => console.log(data));

The async keyword

But there's still something vaguely dissatisfying about having to write code one way if synchronous and a quite different way if asynchronous. For synchronous, we write

a();
b();

but if a is asynchronous, with promises we have to write

a() . then(b);

Above, we said, "JS has no way to know that it needs to wait for the first call to finish before it executes the second". Wouldn't it be nice if there was some way to tell JS that? It turns out that there is--the await keyword, used inside a special type of function called an "async" function. This feature is part of the upcoming version of ES but is already available in transpilers such as Babel given the right presets. This allows us to simply write

async function morning_routine() {
  var milk   = await order_milk();
  var coffee = await put_in_coffee(milk);
  await drink(coffee);
}

In your case, you would be able to write something like

async function foo() {
  data = await get_data();
  console.log(data);
}

Add double quote

$nameRegex = "chalmw-dm*"

-like "$nameregex" or -like "'$nameregex'"

Here is an example using openssl_encrypt

//Encryption:
$textToEncrypt = "My Text to Encrypt";
$encryptionMethod = "AES-256-CBC";
$secretHash = "encryptionhash";
$iv = mcrypt_create_iv(16, MCRYPT_RAND);
$encryptedText = openssl_encrypt($textToEncrypt,$encryptionMethod,$secretHash, 0, $iv);

//Decryption:
$decryptedText = openssl_decrypt($encryptedText, $encryptionMethod, $secretHash, 0, $iv);
print "My Decrypted Text: ". $decryptedText;

This will also checks in leap year. This is pure regex, so it's faster than any lib (also faster than moment.js). But if you gonna use a lot of dates in ur code, I do recommend to use moment.js

var dateRegex = /^(?=\d)(?:(?:31(?!.(?:0?[2469]|11))|(?:30|29)(?!.0?2)|29(?=.0?2.(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00)))(?:\x20|$))|(?:2[0-8]|1\d|0?[1-9]))([-.\/])(?:1[012]|0?[1-9])\1(?:1[6-9]|[2-9]\d)?\d\d(?:(?=\x20\d)\x20|$))?(((0?[1-9]|1[012])(:[0-5]\d){0,2}(\x20[AP]M))|([01]\d|2[0-3])(:[0-5]\d){1,2})?$/;

console.log(dateRegex.test('21/01/1986'));

Also in your storyboard, without single line of code

Here's the example from my code. So I will read a text from 1st line to 3rd line using readLine() and then store to array variable and print into textfield using for-loop :

QFile file("file.txt");

    if(!file.open(QIODevice::ReadOnly | QIODevice::Text))
        return;

    QTextStream in(&file);
    QString line[3] = in.readLine();
    for(int i=0; i<3; i++)
    {
        ui->textEdit->append(line[i]);
    }

I faced the similar issue on new server that I built through automated scripts via vcenter api. Looks like the "Remote Procedure Call (RPC)" service may not be running on the remote machine. you need to wait for the service to come up to use the Get-WmiObject command. Hence I simply put the script into sleep for sometime and it worked.

Althugh you asked for Google Maps API, I suggest an open source, working, legal, free and crowdsourced API by Open street maps

https://nominatim.openstreetmap.org/search?q=Mumbai&format=json

Here is the API documentation for reference.

Edit: It looks like there are discrepancies occasionally, at least in terms of postal codes, when compared to the Google Maps API, and the latter seems to be more accurate. This was the case when validating addresses in Canada with the Canada Post search service, however, it might be true for other countries too.

There are number of ways to do it:

Using filter() (and operator)

query = meta.Session.query(User).filter(
    User.firstname.like(search_var1),
    User.lastname.like(search_var2)
    )

Using filter_by() (and operator)

query = meta.Session.query(User).filter_by(
    firstname.like(search_var1),
    lastname.like(search_var2)
    )

Chaining filter() or filter_by() (and operator)

query = meta.Session.query(User).\
    filter_by(firstname.like(search_var1)).\
    filter_by(lastname.like(search_var2))

Using or_(), and_(), and not()

from sqlalchemy import and_, or_, not_

query = meta.Session.query(User).filter(
    and_(
        User.firstname.like(search_var1),
        User.lastname.like(search_var2)
    )
)

According the to Windows Dev Center WIN32_LEAN_AND_MEAN excludes APIs such as Cryptography, DDE, RPC, Shell, and Windows Sockets.

The tutorial is cheating because it is starting with a greyscale image encoded in RGB, so they are just slicing a single color channel and treating it as greyscale. The basic steps you need to do are to transform from the RGB colorspace to a colorspace that encodes with something approximating the luma/chroma model, such as YUV/YIQ or HSL/HSV, then slice off the luma-like channel and use that as your greyscale image. matplotlib does not appear to provide a mechanism to convert to YUV/YIQ, but it does let you convert to HSV.

Try using matplotlib.colors.rgb_to_hsv(img) then slicing the last value (V) from the array for your grayscale. It's not quite the same as a luma value, but it means you can do it all in matplotlib.

Background:

• http://matplotlib.sourceforge.net/api/colors_api.html
• http://en.wikipedia.org/wiki/HSL_and_HSV

Alternatively, you could use PIL or the builtin colorsys.rgb_to_yiq() to convert to a colorspace with a true luma value. You could also go all in and roll your own luma-only converter, though that's probably overkill.

The answer I got is that variables and subqueries will not work and we have to user dynamic SQL script. The following works:

DECLARE @SQL VARCHAR(4000)
SET @SQL = 'ALTER TABLE dbo.Student DROP CONSTRAINT |ConstraintName| '

SET @SQL = REPLACE(@SQL, '|ConstraintName|', ( SELECT   name
                                               FROM     sysobjects
                                               WHERE    xtype = 'PK'
                                                        AND parent_obj =        OBJECT_ID('Student')))

EXEC (@SQL)

Yes its called negative lookahead. It goes like this - (?!regex here). So abc(?!def) will match abc not followed by def. So it'll match abce, abc, abck, etc.

Similarly there is positive lookahead - (?=regex here). So abc(?=def) will match abc followed by def.

There are also negative and positive lookbehind - (?<!regex here) and (?<=regex here) respectively

One point to note is that the negative lookahead is zero-width. That is, it does not count as having taken any space.

So it may look like a(?=b)c will match "abc" but it won't. It will match 'a', then the positive lookahead with 'b' but it won't move forward into the string. Then it will try to match the 'c' with 'b' which won't work. Similarly ^a(?=b)b$ will match 'ab' and not 'abb' because the lookarounds are zero-width (in most regex implementations).

The biggest problem with your code is that it's unreadable. Python code rule number one, if it's not readable, no one's gonna look at it for long enough to get any useful information out of it. Always use descriptive variable names. Almost didn't catch the bug in your code, let's see it again with good names, slow-motion replay style:

to_modify = [5,4,3,2,1,0]
indexes = [0,1,3,5]
replacements = [0,0,0,0]

for index in indexes:
    to_modify[indexes[index]] = replacements[index]
    # to_modify[indexes[index]]
    # indexes[index]
    # Yo dawg, I heard you liked indexes, so I put an index inside your indexes
    # so you can go out of bounds while you go out of bounds.

As is obvious when you use descriptive variable names, you're indexing the list of indexes with values from itself, which doesn't make sense in this case.

Also when iterating through 2 lists in parallel I like to use the zip function (or izip if you're worried about memory consumption, but I'm not one of those iteration purists). So try this instead.

for (index, replacement) in zip(indexes, replacements):
    to_modify[index] = replacement

If your problem is only working with lists of numbers then I'd say that @steabert has the answer you were looking for with that numpy stuff. However you can't use sequences or other variable-sized data types as elements of numpy arrays, so if your variable to_modify has anything like that in it, you're probably best off doing it with a for loop.

React provides an interface for what you are trying to do via the ref attribute. Assign a component a ref, and its current attribute will be your custom component:

class Parent extends React.Class {
    constructor(props) {
        this._child = React.createRef();
    }

    componentDidMount() {
        console.log(this._child.current.someMethod()); // Prints 'bar'
    }

    render() {
        return (
            <div>
                <Child ref={this._child} />
            </div>
        );
    }
}

Note: This will only work if the child component is declared as a class, as per documentation found here: https://facebook.github.io/react/docs/refs-and-the-dom.html#adding-a-ref-to-a-class-component

Update 2019-04-01: Changed example to use a class and createRef per latest React docs.

Update 2016-09-19: Changed example to use ref callback per guidance from the ref String attribute docs.

Function Concat(myRange As Range, Optional myDelimiter As String) As String 
  Dim r As Range 
  Application.Volatile 
  For Each r In myRange 
    If Len(r.Text) Then 
      Concat = Concat & IIf(Concat <> "", myDelimiter, "") & r.Text 
    End If 
  Next 
End Function

Both are supported. To quote the Arduino homepage,

The core libraries are written in C and C++ and compiled using avr-gcc

Note that C++ is a superset of C (well, almost), and thus can often look very similar. I am not an expert, but I guess that most of what you will program for the Arduino in your first year on that platform will not need anything but plain C.

I assume you know what a byte is. A byte array is simply an area of memory containing a group of contiguous (side by side) bytes, such that it makes sense to talk about them in order: the first byte, the second byte etc..

Just as bytes can encode different types and ranges of data (numbers from 0 to 255, numbers from -128 to 127, single characters using ASCII e.g. 'a' or '%', CPU op-codes), each byte in a byte array may be any of these things, or contribute to some multi-byte values such as numbers with larger range (e.g. 16-bit unsigned int from 0..65535), international character sets, textual strings ("hello"), or part/all of a compiled computer programs.

The crucial thing about a byte array is that it gives indexed (fast), precise, raw access to each 8-bit value being stored in that part of memory, and you can operate on those bytes to control every single bit. The bad thing is the computer just treats every entry as an independent 8-bit number - which may be what your program is dealing with, or you may prefer some powerful data-type such as a string that keeps track of its own length and grows as necessary, or a floating point number that lets you store say 3.14 without thinking about the bit-wise representation. As a data type, it is inefficient to insert or remove data near the start of a long array, as all the subsequent elements need to be shuffled to make or fill the gap created/required.

Windows uses .cer extension for an X.509 certificate. These can be in "binary" (ASN.1 DER), or it can be encoded with Base-64 and have a header and footer applied (PEM); Windows will recognize either. To verify the integrity of a certificate, you have to check its signature using the issuer's public key... which is, in turn, another certificate.

Windows uses .pfx for a PKCS #12 file. This file can contain a variety of cryptographic information, including certificates, certificate chains, root authority certificates, and private keys. Its contents can be cryptographically protected (with passwords) to keep private keys private and preserve the integrity of root certificates.

Windows uses .pvk for a private key file. I'm not sure what standard (if any) Windows follows for these. Hopefully they are PKCS #8 encoded keys. Emmanuel Bourg reports that these are a proprietary format. Some documentation is available.

You should never disclose your private key. These are contained in .pfx and .pvk files.

Generally, you only exchange your certificate (.cer) and the certificates of any intermediate issuers (i.e., the certificates of all of your CAs, except the root CA) with other parties.

<?php
ini_set("SMTP", "aspmx.l.google.com");

You can run the pipenv command with the --rm option as in:

pipenv --rm

This will remove the virtualenv created for you under ~/.virtualenvs

See https://pipenv.kennethreitz.org/en/latest/cli/#cmdoption-pipenv-rm

http://www.php.net/manual/en/function.call-user-func-array.php

call_user_func_array('func',$myArgs);

nameContent only exists within the first() function, as you defined it within the first() function.

To make its scope broader, define it outside of the functions:

var nameContent;

function first(){
    nameContent=document.getElementById('full_name').value;
}

function second() {
    first();
    y=nameContent; alert(y);
}
second();

A slightly better approach would be to return the value, as global variables get messy very quickly:

function getFullName() {
  return document.getElementById('full_name').value;
}

function doStuff() {
  var name = getFullName();

  alert(name);
}

doStuff();

your break statement should break out of the for (in in 1:n).

Personally I am always wary with break statements and double check it by printing to the console to double check that I am in fact breaking out of the right loop. So before you test add the following statement, which will let you know if you break before it reaches the end. However, I have no idea how you are handling the variable n so I don't know if it would be helpful to you. Make a n some test value where you know before hand if it is supposed to break out or not before reaching n.

for (in in 1:n)
{
    if (in == n)         #add this statement
    {
        "sorry but the loop did not break"
    }

    id_novo <- new_table_df$ID[in]
    if(id_velho==id_novo)
    {
        break
    }
    else if(in == n)
    {
        sold_df <- rbind(sold_df,old_table_df[out,])
    }
}

Easy way

class ViewController: UIViewController {

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

I am answering this for android studio 2.3.1. One of the easiest ways to set RelativeLayout as default layout is going to text mode and editing the XML file as follows:

Change this line:

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

To

<android.widget.RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

And do check your ending tag changes to this:

</android.widget.RelativeLayout>

Also (optionally) go ahead and delete this line if it's being shown in grey:

xmlns:app="http://schemas.android.com/apk/res-auto"

Edit:

This is an optional change to make in project, I came across this tip while going through Udacity's Android Developer Course

If the constraint layout is not needed in the project remove the following dependency from build.gradle by deleting this line and then doing gradle sync:

    compile 'com.android.support.constraint:constraint-layout:1.0.0-beta4'

Cursor itself is an iterator (like WHILE). By saying iterator I mean a way to traverse the record set (aka a set of selected data rows) and do operations on it while traversing. Operations could be INSERT or DELETE for example. Hence you can use it for data retrieval for example. Cursor works with the rows of the result set sequentially - row by row. A cursor can be viewed as a pointer to one row in a set of rows and can only reference one row at a time, but can move to other rows of the result set as needed.

This link can has a clear explanation of its syntax and contains additional information plus examples.

Cursors can be used in Sprocs too. They are a shortcut that allow you to use one query to do a task instead of several queries. However, cursors recognize scope and are considered undefined out of the scope of the sproc and their operations execute within a single procedure. A stored procedure cannot open, fetch, or close a cursor that was not declared in the procedure.

This topic is quite old, but here is a handy solution that I found:

http://www.cityinthesky.co.uk/opensource/pdf2svg/

It offers a tool, pdf2png, which once installed does exactly the job in command line. I've tested it with irreproachable results so far, including with bitmaps.

EDIT : My mistake, this tool also converts letters to paths, so it does not address the initial question. However it does a good job anyway, and can be useful to anyone who does not intend to modify the code in the svg file, so I'll leave the post.

Here is one for DOS or Unix new line:

    void chomp( string &s)
    {
            int pos;
            if((pos=s.find('\n')) != string::npos)
                    s.erase(pos);
    }

Artistically, if you need to fit two or more lines of text within the same width regardless of their character count then you have nice options.

It's best to find a dynamical solution so whatever text is entered we end up with a nice display.

Let's see how we may approach.

var els     = document.querySelectorAll(".divtext"),_x000D_
refWidth    = els[0].clientWidth,_x000D_
refFontSize = parseFloat(window.getComputedStyle(els[0],null)_x000D_
                               .getPropertyValue("font-size"));_x000D_
_x000D_
els.forEach((el,i) => el.style.fontSize = refFontSize * refWidth / els[i].clientWidth + "px")

#container {_x000D_
  display: inline-block;_x000D_
  background-color: black;_x000D_
  padding: 0.6vw 1.2vw;_x000D_
}_x000D_
.divtext {_x000D_
  display: table;_x000D_
  color: white;_x000D_
  font-family: impact;_x000D_
  font-size: 4.5vw;_x000D_
}

<div id="container">_x000D_
  <div class="divtext">THIS IS JUST AN</div>_x000D_
  <div class="divtext">EXAMPLE</div>_x000D_
  <div class="divtext">TO SHOW YOU WHAT</div>_x000D_
  <div class="divtext">YOU WANT</div>_x000D_
</div>

All we do is to get the width (els[0].clientWidth) and the font size (parseFloat(window.getComputedStyle(els[0],null).getPropertyValue("font-size"))) of the first line as a reference and then just calculate the subsequent lines font size accordingly.

You can use Map.

• A new data structure introduced in JavaScript ES6.
• Alternative to JavaScript Object for storing key/value pairs.
• Has useful methods for iteration over the key/value pairs.

var map = new Map();
map.set('name', 'John');
map.set('id', 11);

// Get the full content of the Map
console.log(map); // Map { 'name' => 'John', 'id' => 11 }

Get value of the Map using key

console.log(map.get('name')); // John 
console.log(map.get('id')); // 11

Get size of the Map

console.log(map.size); // 2

Check key exists in Map

console.log(map.has('name')); // true
console.log(map.has('age')); // false

Get keys

console.log(map.keys()); // MapIterator { 'name', 'id' }

Get values

console.log(map.values()); // MapIterator { 'John', 11 }

Get elements of the Map

for (let element of map) {
  console.log(element);
}

// Output:
// [ 'name', 'John' ]
// [ 'id', 11 ]

Print key value pairs

for (let [key, value] of map) {
  console.log(key + " - " + value);
}

// Output: 
// name - John
// id - 11

Print only keys of the Map

for (let key of map.keys()) {
  console.log(key);
}

// Output:
// name
// id

Print only values of the Map

for (let value of map.values()) {
  console.log(value);
}

// Output:
// John
// 11

If you are using Java 6 or higher you can use wildcards of this form:

java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp

If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:

java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp

There is nothing like lib\*\* or lib\** wildcard for the kind of job you want to be done.

Intervention Image is an open source PHP image handling and manipulation library http://image.intervention.io/

This library provides a lot of useful features:

Basic Examples

// open an image file
$img = Image::make('public/foo.jpg');

// now you are able to resize the instance
$img->resize(320, 240);

// and insert a watermark for example
$img->insert('public/watermark.png');

// finally we save the image as a new file
$img->save('public/bar.jpg');

Method chaining:

$img = Image::make('public/foo.jpg')->resize(320, 240)->insert('public/watermark.png');

Tips: (In your case) https://laracasts.com/discuss/channels/laravel/file-upload-isvalid-returns-false

Tips 1:

// Tell the validator input file should be an image & check this validation
$rules = array(
  'image' => 'mimes:jpeg,jpg,png,gif,svg  // allowed type
              |required                  // is required field
              |max:2048'               // max 2MB
              |min:1024               // min 1MB
  );
// validator Rules
$validator = Validator::make($request->only('image'), $rules);

// Check validation (fail or pass)
if ($validator->fails())
{
    //Error do your staff
} else
{
    //Success do your staff
};

Tips 2:

if you want to upgrade only a single column of a table row then you can use as following:

$this->db->set('column_header', $value); //value that used to update column  
$this->db->where('column_id', $column_id_value); //which row want to upgrade  
$this->db->update('table_name');  //table name

Do display: inline-block:

#report-upload-form label {
    padding-left:26px;
    width:125px;
    text-transform: uppercase;
    display:inline-block
}

In your component's template you can use multiple arguments by separating them with colons:

{{ myData | myPipe: 'arg1':'arg2':'arg3'... }}

From your code it will look like this:

new MyPipe().transform(myData, arg1, arg2, arg3)

And in your transform function inside your pipe you can use the arguments like this:

export class MyPipe implements PipeTransform { 
    // specify every argument individually   
    transform(value: any, arg1: any, arg2: any, arg3: any): any { }
    // or use a rest parameter
    transform(value: any, ...args: any[]): any { }
}

Beta 16 and before (2016-04-26)

Pipes take an array that contains all arguments, so you need to call them like this:

new MyPipe().transform(myData, [arg1, arg2, arg3...])

And your transform function will look like this:

export class MyPipe implements PipeTransform {    
    transform(value:any, args:any[]):any {
        var arg1 = args[0];
        var arg2 = args[1];
        ...
    }
}

Though you can have several <form> elements in one HTML page, you cannot nest them.

This is how session state works in ASP.NET and ASP.NET MVC:

ASP.NET Session State Overview

Basically, you do this to store a value in the Session object:

Session["FirstName"] = FirstNameTextBox.Text;

To retrieve the value:

var firstName = Session["FirstName"];

In OpenedFilesView, under the Options menu, there is a menu item named "Show Network Files". Perhaps with that enabled, the aforementioned utility is of some use.

keyCode and which represent the actual keyboard key pressed in the form of a numeric value. The reason both exist is that keyCode is available within Internet Explorer while which is available in W3C browsers like FireFox.

charCode is similar, but in this case you retrieve the Unicode value of the character pressed. For example, the letter "A."

The JavaScript expression:

var keyCode = e.keyCode ? e.keyCode : e.charCode;

Essentially says the following:

If the e.keyCode property exists, set variable keyCode to its value. Otherwise, set variable keyCode to the value of the e.charCode property.

Note that retrieving the keyCode or charCode properties typically involve figuring out differences between the event models in IE and in W3C. Some entails writing code like the following:

/*
 get the event object: either window.event for IE 
 or the parameter e for other browsers
*/
var evt = window.event ? window.event : e;
/*
 get the numeric value of the key pressed: either 
 event.keyCode for IE for e.which for other browsers
*/
var keyCode = evt.keyCode ? evt.keyCode : e.which;

EDIT: Corrections to my explanation of charCode as per Tor Haugen's comments.

You can do this without using Javascript using only HTML You need to set default select option disabled="" and selected="" and select tag required="". Browser doesn't allow user to submit the form without selecting an option.

<form action="" method="POST">
    <select name="in-op" required="">
        <option disabled="" selected="">Select Option</option>
        <option>Option 1</option>
        <option>Option 2</option>
        <option>Option 3</option>
    </select>
    <input type="submit" value="Submit">
</form>

Is it possible the root password is not what you think it is? Have you checked the file /root/.mysql_secret for the password? That is the default location for the automated root password that is generated from starting from version 5.7.

cat /root/.mysql_secret

You can pass multiple args to log:

console.log("story", name, "story");

Actually Windows does have a utility that encodes and decodes base64 - CERTUTIL

I'm not sure what version of Windows introduced this command.

To encode a file:

certutil -encode inputFileName encodedOutputFileName

To decode a file:

certutil -decode encodedInputFileName decodedOutputFileName

There are a number of available verbs and options available to CERTUTIL.

To get a list of nearly all available verbs:

certutil -?

To get help on a particular verb (-encode for example):

certutil -encode -?

To get complete help for nearly all verbs:

certutil -v -?

Mysteriously, the -encodehex verb is not listed with certutil -? or certutil -v -?. But it is described using certutil -encodehex -?. It is another handy function :-)

Update

Regarding David Morales' comment, there is a poorly documented type option to the -encodehex verb that allows creation of base64 strings without header or footer lines.

certutil [Options] -encodehex inFile outFile [type]

A type of 1 will yield base64 without the header or footer lines.

See https://www.dostips.com/forum/viewtopic.php?f=3&t=8521#p56536 for a brief listing of the available type formats. And for a more in depth look at the available formats, see https://www.dostips.com/forum/viewtopic.php?f=3&t=8521#p57918.

Not investigated, but the -decodehex verb also has an optional trailing type argument.

How to convert bytes as seen to strings, even in weird situations.

As your code may have unrecognizable characters to 'utf-8' encoding, it's better to use just str without any additional parameters:

some_bad_bytes = b'\x02-\xdfI#)'
text = str( some_bad_bytes )[2:-1]

print(text)

Output: \x02-\xdfI

if you add 'utf-8' parameter, to these specific bytes, you should receive error.

As PYTHON 3 standard says, text would be in utf-8 now with no concern.

You can use the following command on the command prompt (cmd) on Windows:

py -3.3 -m pip install opencv-python

I made a video on how to install OpenCV Python on Windows in 1 minute here:

If you using Deno JavaScript and TypeScript runtime and you enable experimentalDecorators:true in tsconfig.json or the VSCode ide settings. It will not work. According to Deno requirement, you need to provide tsconfig as a flag when running a Deno file. See Custom TypeScript Compiler Options

In my particular case I was running a Deno test and used.

$ deno test -c tsconfig.json

If it is a file, you have something like

 $ deno run -c tsconfig.json mod.ts

my tsconfig.json

{
  "compilerOptions": {
    "allowJs": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "module": "esnext"
  }
}

Hope this will help somebody to develop custom checkbox component with custom styles. This solution can use with forms too.

HTML

<label class="lbl">

  <input #inputEl type="checkbox" [name]="label" [(ngModel)]="isChecked" (change)="onChange(inputEl.checked)"
   *ngIf="isChecked" checked>
  <input #inputEl type="checkbox" [name]="label" [(ngModel)]="isChecked" (change)="onChange(inputEl.checked)"
   *ngIf="!isChecked" >
  <span class="chk-box {{isChecked ? 'chk':''}}"></span>
  <span class="lbl-txt" *ngIf="label" >{{label}}</span>
</label>

    import { Component, Input, EventEmitter, Output, forwardRef, HostListener } from '@angular/core';
import { ControlValueAccessor, NG_VALUE_ACCESSOR } from '@angular/forms';

};

export class CheckboxComponent implements ControlValueAccessor {


  @Input() label: string;
  @Input() isChecked = false;
  @Input() disabled = false;
  @Output() getChange = new EventEmitter();
  @Input() className: string;

  // get accessor
  get value(): any {
    return this.isChecked;
  }

  // set accessor including call the onchange callback
  set value(value: any) {
    this.isChecked = value;
  }

  private onTouchedCallback: () => void = noop;
  private onChangeCallback: (_: any) => void = noop;


  writeValue(value: any): void {
    if (value !== this.isChecked) {
      this.isChecked = value;
    }
  }

Usage

Outside forms

<app-checkbox [label]="'Example'" [isChecked]="true"></app-checkbox>

Inside forms

<app-checkbox [label]="'Type 0'" formControlName="Type1"></app-checkbox>

Try this:

<marquee behavior="" Height="200px"  direction="up" scroll onmouseover="this.setAttribute('scrollamount', 0, 0);this.stop();" onmouseout="this.setAttribute('scrollamount', 3, 0);this.start();" scrollamount="3" valign="center">

    <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
    </marquee>

In this case a relatively simple GROUP BY can work, but in general, when there are additional columns where you can't order by but you want them from the particular row which they are associated with, you can either join back to the detail using all the parts of the key or use OVER():

What does res.render do and what does the html file look like?

res.render() function compiles your template (please don't use ejs), inserts locals there, and creates html output out of those two things.

Answering Edit 2 part.

// here you set that all templates are located in `/views` directory
app.set('views', __dirname + '/views');

// here you set that you're using `ejs` template engine, and the
// default extension is `ejs`
app.set('view engine', 'ejs');

// here you render `orders` template
response.render("orders", {orders: orders_json});

So, the template path is views/ (first part) + orders (second part) + .ejs (third part) === views/orders.ejs

Anyway, express.js documentation is good for what it does. It is API reference, not a "how to use node.js" book.

This solved my problem, from preventign that an event gets fired by a children:

doSmth(){_x000D_
  // what ever_x000D_
}

        <div (click)="doSmth()">_x000D_
            <div (click)="$event.stopPropagation()">_x000D_
                <my-component></my-component>_x000D_
            </div>_x000D_
        </div>

In addition to accepted answer, if you're using Entity Migrations for updating database, you should add this line at the beggining of the Up() function in your migration file:

Sql("alter table dbo.CompanyTransactions drop constraint [df__CompanyTr__Creat__0cdae408];");

You can find the constraint name in the error at nuget packet manager console which starts with FK_dbo.

If I remember correctly, Bluetooth defines certain roles that devices can take. Most cell phones only support a certain number of roles. For instance, I can have a Bluetooth stereo headset that connects to my phone to receive audio, but just because my cell phone has Bluetooth does mean that it supports BEING a speaker for a different device - it doesn't advertise its capabilities of having a speaker for use by other Bluetooth devices.

I assume you want to transfer files between two iPhones? Transferring files via Bluetooth does seem like functionality that I would put in the iPhone, but I'm not Apple so I don't know for sure. In fact, yes, it seems that file transfer is not supported except in jailbroken phones:

http://gizmodo.com/5138797/iphone-bluetooth-file-transfer-coming-soon-yes

You'll probably get similar answers for Bluetooth Dial-Up Networking. I'd imagine they kept the Bluetooth commands out of the SDK for various reasons and you'll have to jailbreak your phone to get the functionality back.

I was testing my application with special characters & was observing the same error. After some research, turns out the % symbol was the cause. I had to modify it to the encoded representation %25. Its all fine now, thanks to the below post

https://superuser.com/questions/759959/why-does-the-percent-sign-in-a-url-cause-an-http-400-bad-request-error

If you don't want any separator after the last cell, then you need a close to zero but non-zero height for your footer.

In your UITableViewDelegate:

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    return .leastNormalMagnitude
}

For me that have Visual Studio 2015 this works:
Search this in the start menu: Developer Command Prompt for VS2015 and run the program in the search result.
You can now execute your command in it, for example: cl /?

In my case I was missing new inside the type definition.

some-js-component.d.ts file:

import * as React from "react";

export default class SomeJSXComponent extends React.Component<any, any> {
    new (props: any, context?: any)
}

and inside the tsx file where I was trying to import the untyped component:

import SomeJSXComponent from 'some-js-component'

const NewComp = ({ asdf }: NewProps) => <SomeJSXComponent withProps={asdf} />

Something like this should do it :

UPDATE table1 
   SET table1.Price = table2.price 
   FROM table1  INNER JOIN  table2 ON table1.id = table2.id

You can also try this:

UPDATE table1 
   SET price=(SELECT price FROM table2 WHERE table1.id=table2.id);

This post is just to mention an additional option. In case you need to set custom R libs in your Linux shell script you may easily do so by

export R_LIBS="~/R/lib"

See R admin guide on complete list of options.

Lodash has an utility function for this as well: https://lodash.com/docs#difference

In Bash shell:

#!/bin/sh

COUNTER=1

while [ $COUNTER -lt 254 ]
do
   ping 192.168.1.$COUNTER -c 1
   COUNTER=$(( $COUNTER + 1 ))
done

I use this method to get complete path to jar or exe.

File pto = new File(YourClass.class.getProtectionDomain().getCodeSource().getLocation().toURI());

pto.getAbsolutePath());

In swift 5

https://www.hackingwithswift.com/example-code/strings/how-to-capitalize-the-first-letter-of-a-string

extension String {
    func capitalizingFirstLetter() -> String {
        return prefix(1).capitalized + dropFirst()
    }

    mutating func capitalizeFirstLetter() {
        self = self.capitalizingFirstLetter()
    }
}

use with your string

let test = "the rain in Spain"
print(test.capitalizingFirstLetter())

In case you are using bundler, you need to add something like this to your Gemfile:

gem 'redcarpet', :git => 'git://github.com/tanoku/redcarpet.git'

And in case there is .gemspec file, it should be able to fetch and install the gem when running bundle install.

UPD. As indicated in comments, for Bundler to function properly you also need to add the following to config.ru:

require "bundler" 
Bundler.setup(:default)

exit in the C language takes an integer representing an exit status.

Exit Success

Typically, an exit status of 0 is considered a success, or an intentional exit caused by the program's successful execution.

Exit Failure

An exit status of 1 is considered a failure, and most commonly means that the program had to exit for some reason, and was not able to successfully complete everything in the normal program flow.

Here's a GNU Resource talking about Exit Status.

As @Als has stated, two constants should be used in place of 0 and 1.

EXIT_SUCCESS is defined by the standard to be zero.

EXIT_FAILURE is not restricted by the standard to be one, but many systems do implement it as one.

No need to find. If you are just looking for a pattern within a specific directory, this should suffice:

grep -hn FOO /your/path/*.bar

Where -h is the parameter to hide the filename, as from man grep:

-h, --no-filename

Suppress the prefixing of file names on output. This is the default when there is only one file (or only standard input) to search.

Note that you were using

-H, --with-filename

Print the file name for each match. This is the default when there is more than one file to search.

You need to configure the security group as stated by cyraxjoe. Along with that you also need to open System port. Steps to open port in windows :-

1. On the Start menu, click Run, type WF.msc, and then click OK.
2. In the Windows Firewall with Advanced Security, in the left pane, right-click Inbound Rules, and then click New Rule in the action pane.
3. In the Rule Type dialog box, select Port, and then click Next.
4. In the Protocol and Ports dialog box, select TCP. Select Specific local ports, and then type the port number , such as 8787 for the default instance. Click Next.
5. In the Action dialog box, select Allow the connection, and then click Next.
6. In the Profile dialog box, select any profiles that describe the computer connection environment when you want to connect , and then click Next.
7. In the Name dialog box, type a name and description for this rule, and then click Finish.

Alternative Swift solution:

static func topMostController() -> UIViewController {
    var topController = UIApplication.sharedApplication().keyWindow?.rootViewController
    while (topController?.presentedViewController != nil) {
        topController = topController?.presentedViewController
    }

    return topController!
}

After spending a good amount of time on this issue I found whenever I followed suggestions of using IIS to make a self signed certificate, I found that the Issued To and Issued by was not correct. SelfSSL.exe was the key to solving this problem. The following website not only provided a step by step approach to making self signed certificates, but also solved the Issued To and Issued by problem. Here is the best solution I found for making self signed certificates. If you'd prefer to see the same tutorial in video form click here.

A sample use of SelfSSL would look something like the following:

SelfSSL /N:CN=YourWebsite.com /V:1000 /S:2

SelfSSL /? will provide a list of parameters with explanation.

You can use auto margins

Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

So you can use one of these (or both):

p { margin-bottom: auto; } /* Push following elements to the bottom */
a { margin-top: auto; } /* Push it and following elements to the bottom */

.content {_x000D_
  height: 200px;_x000D_
  border: 1px solid;_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
}_x000D_
h1, h2 {_x000D_
  margin: 0;_x000D_
}_x000D_
a {_x000D_
  margin-top: auto;_x000D_
}

<div class="content">_x000D_
  <h1>heading 1</h1>_x000D_
  <h2>heading 2</h2>_x000D_
  <p>Some text more or less</p>_x000D_
  <a href="/" class="button">Click me</a>_x000D_
</div>

Alternatively, you can make the element before the a grow to fill the available space:

p { flex-grow: 1; } /* Grow to fill available space */

.content {_x000D_
  height: 200px;_x000D_
  border: 1px solid;_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
}_x000D_
h1, h2 {_x000D_
  margin: 0;_x000D_
}_x000D_
p {_x000D_
  flex-grow: 1;_x000D_
}

<div class="content">_x000D_
  <h1>heading 1</h1>_x000D_
  <h2>heading 2</h2>_x000D_
  <p>Some text more or less</p>_x000D_
  <a href="/" class="button">Click me</a>_x000D_
</div>

to order after the colsum :

order(colSums(people),decreasing=TRUE)

if more than 20+ columns

order(colSums(people[,c(5:25)],decreasing=TRUE) ##in case of keeping the first 4 columns remaining.

props.children represents the content between the opening and the closing tags when invoking/rendering a component:

const Foo = props => (
  <div>
    <p>I'm {Foo.name}</p>
    <p>abc is: {props.abc}</p>

    <p>I have {props.children.length} children.</p>
    <p>They are: {props.children}.</p>
    <p>{Array.isArray(props.children) ? 'My kids are an array.' : ''}</p>
  </div>
);

const Baz = () => <span>{Baz.name} and</span>;
const Bar = () => <span> {Bar.name}</span>;

invoke/call/render Foo:

<Foo abc={123}>
  <Baz />
  <Bar />
</Foo>

For me, only "Integer.toHexString(registered)" worked the way I wanted:

char registered = '®';
System.out.println("Answer:"+Integer.toHexString(registered));

This answer will give you only string representations what are usually presented in the tables. Jon Skeet's answer explains more.

Its working for me Perfectly. SELECT NAME FROM TABLE_NAME WHERE NAME = 'test Name' COLLATE NOCASE

I am assuming you want to set the opacity of the modal background...

Set the opacity via CSS

.modal-backdrop
{
    opacity:0.5 !important;
}

!important prevents the opacity from being overwritten - particularly from Bootstrap in this context.

<button type="button" href="location.href='#/nameOfState'">Title on button</button>

Even more simple... (note the single quotes around the address)

Replace the * with a /

So instead of

COPY * <destination>

use

COPY / <destination>

It is stored in a file called connections.xml under

\Users\[User]\AppData\Roaming\SQL Developer\System\

When I renamed the file, all my connection info went away. I renamed it back, and it all came back. When I viewed the XML file, I found both test connection aliases, ports, usernames, roles, authentication types, etc.

If both application have the same signature (meaning that both APPS are yours and signed with the same key), you can call your other app activity as follows:

Intent LaunchIntent = getActivity().getPackageManager().getLaunchIntentForPackage(CALC_PACKAGE_NAME);
startActivity(LaunchIntent);

Hope it helps.

Assuming that the order is the same in both objects, just stringify them both and compare!

JSON.stringify(obj1) == JSON.stringify(obj2);

auto time = std::time(nullptr);
std::cout << std::put_time(std::localtime(&time), "%F %T%z"); // ISO 8601 format.

Get the current time either using std::time() or std::chrono::system_clock::now() (or another clock type).

std::put_time() (C++11) and strftime() (C) offer a lot of formatters to output those times.

#include <iomanip>
#include <iostream>

int main() {
    auto time = std::time(nullptr);
    std::cout
        // ISO 8601: %Y-%m-%d %H:%M:%S, e.g. 2017-07-31 00:42:00+0200.
        << std::put_time(std::gmtime(&time), "%F %T%z") << '\n'
        // %m/%d/%y, e.g. 07/31/17
        << std::put_time(std::gmtime(&time), "%D"); 
}

The sequence of the formatters matters:

std::cout << std::put_time(std::gmtime(&time), "%c %A %Z") << std::endl;
// Mon Jul 31 00:00:42 2017 Monday GMT
std::cout << std::put_time(std::gmtime(&time), "%Z %c %A") << std::endl;
// GMT Mon Jul 31 00:00:42 2017 Monday

The formatters of strftime() are similar:

char output[100];
if (std::strftime(output, sizeof(output), "%F", std::gmtime(&time))) {
    std::cout << output << '\n'; // %Y-%m-%d, e.g. 2017-07-31
}

Often, the capital formatter means "full version" and lowercase means abbreviation (e.g. Y: 2017, y: 17).

Locale settings alter the output:

#include <iomanip>
#include <iostream>
int main() {
    auto time = std::time(nullptr);
    std::cout << "undef: " << std::put_time(std::gmtime(&time), "%c") << '\n';
    std::cout.imbue(std::locale("en_US.utf8"));
    std::cout << "en_US: " << std::put_time(std::gmtime(&time), "%c") << '\n';
    std::cout.imbue(std::locale("en_GB.utf8"));
    std::cout << "en_GB: " << std::put_time(std::gmtime(&time), "%c") << '\n';
    std::cout.imbue(std::locale("de_DE.utf8"));
    std::cout << "de_DE: " << std::put_time(std::gmtime(&time), "%c") << '\n';
    std::cout.imbue(std::locale("ja_JP.utf8"));
    std::cout << "ja_JP: " << std::put_time(std::gmtime(&time), "%c") << '\n';
    std::cout.imbue(std::locale("ru_RU.utf8"));
    std::cout << "ru_RU: " << std::put_time(std::gmtime(&time), "%c");        
}

Possible output (Coliru, Compiler Explorer):

undef: Tue Aug  1 08:29:30 2017
en_US: Tue 01 Aug 2017 08:29:30 AM GMT
en_GB: Tue 01 Aug 2017 08:29:30 GMT
de_DE: Di 01 Aug 2017 08:29:30 GMT
ja_JP: 2017?08?01? 08?29?30?
ru_RU: ?? 01 ??? 2017 08:29:30

I've used std::gmtime() for conversion to UTC. std::localtime() is provided to convert to local time.

Heed that asctime()/ctime() which were mentioned in other answers are marked as deprecated now and strftime() should be preferred.

If you use it extensively (a lot of written lines), you can subclass 'file':

class cfile(file):
    #subclass file to have a more convienient use of writeline
    def __init__(self, name, mode = 'r'):
        self = file.__init__(self, name, mode)

    def wl(self, string):
        self.writelines(string + '\n')

Now it offers an additional function wl that does what you want:

fid = cfile('filename.txt', 'w')
fid.wl('appends newline charachter')
fid.wl('is written on a new line')
fid.close()

Maybe I am missing something like different newline characters (\n, \r, ...) or that the last line is also terminated with a newline, but it works for me.

There's no (safe) way to pause execution. You can, however, do something like this using setTimeout:

function writeNext(i)
{
    document.write(i);

    if(i == 5)
        return;

    setTimeout(function()
    {
        writeNext(i + 1);

    }, 2000);
}

writeNext(1);

The purpose of ForEach is to cause side effects. IEnumerable is for lazy enumeration of a set.

This conceptual difference is quite visible when you consider it.

SomeEnumerable.ForEach(item=>DataStore.Synchronize(item));

This wont execute until you do a "count" or a "ToList()" or something on it. It clearly is not what is expressed.

You should use the IEnumerable extensions for setting up chains of iteration, definining content by their respective sources and conditions. Expression Trees are powerful and efficient, but you should learn to appreciate their nature. And not just for programming around them to save a few characters overriding lazy evaluation.

This seems to explain it.

The definition of order is that a[order(a)] is in increasing order. This works with your example, where the correct order is the fourth, second, first, then third element.

You may have been looking for rank, which returns the rank of the elements
R> a <- c(4.1, 3.2, 6.1, 3.1)
R> order(a)
[1] 4 2 1 3
R> rank(a)
[1] 3 2 4 1
so rank tells you what order the numbers are in, order tells you how to get them in ascending order.

plot(a, rank(a)/length(a)) will give a graph of the CDF. To see why order is useful, though, try plot(a, rank(a)/length(a),type="S") which gives a mess, because the data are not in increasing order

If you did
oo<-order(a)
plot(a[oo],rank(a[oo])/length(a),type="S")
or simply
oo<-order(a)
plot(a[oo],(1:length(a))/length(a)),type="S")
you get a line graph of the CDF.

I'll bet you're thinking of rank.

try
{
    $tableAresults = $dbHandler->doSomethingWithTableA();
    if(!tableAresults)
    {
        throw new Exception('Problem with tableAresults');
    }
    $tableBresults = $dbHandler->doSomethingElseWithTableB();
    if(!tableBresults) 
    {
        throw new Exception('Problem with tableBresults');
    }
} catch (Exception $e)
{
    echo $e->getMessage();
}

Write a util function like

public class ListUtil{

    public static int sum(List<Integer> list){
      if(list==null || list.size()<1)
        return 0;

      int sum = 0;
      for(Integer i: list)
        sum = sum+i;

      return sum;
    }
}

Then use like

int sum = ListUtil.sum(yourArrayList)
