Programs & Examples On #Jsoncpp

storing peoples like this

{"Anna" : { 
  "age": 18,
  "profession": "student"},
"Ben" : {
  "age" : "nineteen",
  "profession": "mechanic"}
 }

will cause problems, particularly if differents peoples have same name..

rather use array storing objects like this

{
  "peoples":[
       { 
           "name":"Anna",  
           "age": 18,
           "profession": "student"
       },
       {
           "name":"Ben",
           "age" : "nineteen",
           "profession": "mechanic"
       } 
  ]
}

like this, you can enumerates objects, or acces objects by numerical index. remember that json is storage structure, not dynamically sorter or indexer. use data stored in json to build indexes as you need and acces data.

Just wrote before for the same reason (works with any amount of arrays):

/**
 * Returns with the union of the given arrays.
 *
 * @param Any amount of arrays to be united.
 * @returns {array} The union array.
 */
function uniteArrays()
{
    var union = [];
    for (var argumentIndex = 0; argumentIndex < arguments.length; argumentIndex++)
    {
        eachArgument = arguments[argumentIndex];
        if (typeof eachArgument !== 'array')
        {
            eachArray = eachArgument;
            for (var index = 0; index < eachArray.length; index++)
            {
                eachValue = eachArray[index];
                if (arrayHasValue(union, eachValue) == false)
                union.push(eachValue);
            }
        }
    }

    return union;
}    

function arrayHasValue(array, value)
{ return array.indexOf(value) != -1; }

Another option is to run the two inserts separately, leaving the FK column null, then running an update to poulate it correctly.

If there is nothing natural stored within the two tables that match from one record to another (likely) then create a temporary GUID column and populate this in your data and insert to both fields. Then you can update with the proper FK and null out the GUIDs.

E.g.:

CREATE TABLE [dbo].[table1] ( 
    [id] [int] IDENTITY(1,1) NOT NULL, 
    [data] [varchar](255) NOT NULL, 
    CONSTRAINT [PK_table1] PRIMARY KEY CLUSTERED ([id] ASC),
    JoinGuid UniqueIdentifier NULL
) 

CREATE TABLE [dbo].[table2] ( 
    [id] [int] IDENTITY(1,1) NOT NULL, 
    [table1_id] [int] NULL, 
    [data] [varchar](255) NOT NULL, 
    CONSTRAINT [PK_table2] PRIMARY KEY CLUSTERED ([id] ASC),
    JoinGuid UniqueIdentifier NULL
) 


INSERT INTO Table1....

INSERT INTO Table2....

UPDATE b
SET table1_id = a.id
FROM Table1 a
JOIN Table2 b on a.JoinGuid = b.JoinGuid
WHERE b.table1_id IS NULL

UPDATE Table1 SET JoinGuid = NULL
UPDATE Table2 SET JoinGuid = NULL

And why not just count them ?

import sys
a = sys.argv
if len(a) = 1 :  
    # No arguments were given, the program name count as one
elif len(a) = 4 :
    # Three arguments were given
else :
    # another amount of arguments was given

Simplest way to do this is:

import boto3
s3 = boto3.resource("s3")
bucket_source = {
            'Bucket': "my-bcuket",
            'Key': "file_path_in_bucket"
        }
s3.meta.client.delete(bucket_source)

If you want an alternative to pickle or json, you can use klepto.

>>> init = {'y': 2, 'x': 1, 'z': 3}
>>> import klepto
>>> cache = klepto.archives.file_archive('memo', init, serialized=False)
>>> cache        
{'y': 2, 'x': 1, 'z': 3}
>>>
>>> # dump dictionary to the file 'memo.py'
>>> cache.dump() 
>>> 
>>> # import from 'memo.py'
>>> from memo import memo
>>> print memo
{'y': 2, 'x': 1, 'z': 3}

With klepto, if you had used serialized=True, the dictionary would have been written to memo.pkl as a pickled dictionary instead of with clear text.

You can get klepto here: https://github.com/uqfoundation/klepto

dill is probably a better choice for pickling then pickle itself, as dill can serialize almost anything in python. klepto also can use dill.

You can get dill here: https://github.com/uqfoundation/dill

The additional mumbo-jumbo on the first few lines are because klepto can be configured to store dictionaries to a file, to a directory context, or to a SQL database. The API is the same for whatever you choose as the backend archive. It gives you an "archivable" dictionary with which you can use load and dump to interact with the archive.

Just wanted to mention react-router v4 changed radically since this question was posted/answed.

There is no <Match> component any more! <Switch>is to make sure only the first match is rendered. <Redirect> well .. redirects to another route. Use or leave out exact to either in- or exclude a partial match.

See the docs. They are great. https://reacttraining.com/react-router/

Here's an example I hope is useable to answer your question.

<Router>
  <div>
    <Redirect exact from='/' to='/front'/>
    <Route path="/" render={() => {
      return (
        <div>
          <h2>Home menu</h2>
          <Link to="/front">front</Link>
          <Link to="/back">back</Link>
        </div>
      );
    }} />          
    <Route path="/front" render={() => {
      return (
        <div>
        <h2>front menu</h2>
        <Link to="/front/help">help</Link>
        <Link to="/front/about">about</Link>
        </div>
      );
    }} />
    <Route exact path="/front/help" render={() => {
      return <h2>front help</h2>;
    }} />
    <Route exact path="/front/about" render={() => {
      return <h2>front about</h2>;
    }} />
    <Route path="/back" render={() => {
      return (
        <div>
        <h2>back menu</h2>
        <Link to="/back/help">help</Link>
        <Link to="/back/about">about</Link>
        </div>
      );
    }} />
    <Route exact path="/back/help" render={() => {
      return <h2>back help</h2>;
    }} />
    <Route exact path="/back/about" render={() => {
      return <h2>back about</h2>;
    }} />
  </div>
</Router>

Hope it helped, let me know. If this example is not answering your question well enough, tell me and I'll see if I can modify it.

Variables set at the root-scope are available to the controller scope via prototypical inheritance.

Here is a modified version of @Nitish's demo that shows the relationship a bit clearer: http://jsfiddle.net/TmPk5/6/

Notice that the rootScope's variable is set when the module initializes, and then each of the inherited scope's get their own copy which can be set independently (the change function). Also, the rootScope's value can be updated too (the changeRs function in myCtrl2)

angular.module('myApp', [])
.run(function($rootScope) {
    $rootScope.test = new Date();
})
.controller('myCtrl', function($scope, $rootScope) {
  $scope.change = function() {
        $scope.test = new Date();
    };

    $scope.getOrig = function() {
        return $rootScope.test;
    };
})
.controller('myCtrl2', function($scope, $rootScope) {
    $scope.change = function() {
        $scope.test = new Date();
    };

    $scope.changeRs = function() {
        $rootScope.test = new Date();
    };

    $scope.getOrig = function() {
        return $rootScope.test;
    };
});

Another option:

"My name is Milan, people know me as Milan Vasic"
    .replaceAll("Milan Vasic|Milan", "Milan Vasic"))

Someone should mention that in the question there is a little trap. #ifdef will only check if the following symbol has been defined via #define or by command line, but its value (its substitution in fact) is irrelevant. You could even write

#define one

precompilers accept that. But if you use #if it's another thing.

#define one 0
#if one
    printf("one evaluates to a truth ");
#endif
#if !one
    printf("one does not evaluate to truth ");
#endif

will give one does not evaluate to truth. The keyword defined allows to get the desired behaviour.

#if defined(one) 

is therefore equivalent to #ifdef

The advantage of the #if construct is to allow a better handling of code paths, try to do something like that with the old #ifdef/#ifndef pair.

#if defined(ORA_PROC) || defined(__GNUC) && __GNUC_VERSION > 300

ReSharper does a great job of finding unused code.

In the VS IDE, you can right click on the definition and choose 'Find All References', although this only works at the solution level.

You can use <hr> for a vertical line as well.
Set the width to 1 and the size(height) as long as you want.
I used 500 in my example(demo):

With <hr width="1" size="500">

To your first question:

mysql -u root -p

or

mysqladmin -u root -p "your_command"

depending on what you want to do. The password will be asked of you once you hit enter! I'm guessing you really want to use mysql and not mysqladmin.

For restarting or stopping the MySQL-server on linux, it depends on your installation, but in the common debian derivatives this will work for starting, stopping and restarting the service:

sudo /etc/init.d/mysql start
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql restart
sudo /etc/init.d/mysql status

In some newer distros this might work as well if MySQL is set up as a deamon/service.

sudo service mysql start
sudo service mysql stop
sudo service mysql restart
sudo service mysql status

But the question is really impossible to answer without knowing your particular setup.

I faced the encoding half of this problem the other day. Unhappy with the available options, and after taking a look at this C sample code, i decided to roll my own C++ url-encode function:

#include <cctype>
#include <iomanip>
#include <sstream>
#include <string>

using namespace std;

string url_encode(const string &value) {
    ostringstream escaped;
    escaped.fill('0');
    escaped << hex;

    for (string::const_iterator i = value.begin(), n = value.end(); i != n; ++i) {
        string::value_type c = (*i);

        // Keep alphanumeric and other accepted characters intact
        if (isalnum(c) || c == '-' || c == '_' || c == '.' || c == '~') {
            escaped << c;
            continue;
        }

        // Any other characters are percent-encoded
        escaped << uppercase;
        escaped << '%' << setw(2) << int((unsigned char) c);
        escaped << nouppercase;
    }

    return escaped.str();
}

The implementation of the decode function is left as an exercise to the reader. :P

Keep in mind that there are processes on the database which may not currently support a session.

If you're interested in all processes you'll want to look to v$process (or gv$process on RAC)

There is absolutely no way you can reliably check if there is an internet connection or not (I assume you mean access to the internet).

You can, however, request resources that are virtually never offline, like pinging google.com or something similar. I think this would be efficient.

try { 
    Ping myPing = new Ping();
    String host = "google.com";
    byte[] buffer = new byte[32];
    int timeout = 1000;
    PingOptions pingOptions = new PingOptions();
    PingReply reply = myPing.Send(host, timeout, buffer, pingOptions);
    return (reply.Status == IPStatus.Success);
}
catch (Exception) {
    return false;
}

You could use the Get method and check for null as the method will return null if the NameValueCollection does not contain the specified key.

Add height: 1px to parent container. Works in Chrome, FF, Safari.

Actually there is a simpler way to do this, just:

if ($("#input").is(':empty')) {
console.log('empty');
} else {
console.log('not empty');
}

src: https://www.geeksforgeeks.org/how-to-check-an-html-element-is-empty-using-jquery/

I changed a few things to work with Option Explicit, and the code ran fine against a cell containing "abc.123", which returned "abc.12,". There were no compile errors.

Option Explicit ' This is new

Public Function ProcessString(input_string As String) As String
    ' The temp string used throughout the function
    Dim temp_string As String
    Dim i As Integer ' This is new
    Dim return_string As String ' This is new
    For i = 1 To Len(input_string)
        temp_string = Mid(input_string, i, 1)
        If temp_string Like "[A-Z, a-z, 0-9, :, -]" Then
            return_string = return_string & temp_string
        End If
    Next i
    return_string = Mid(return_string, 1, (Len(return_string) - 1))
    ProcessString = return_string & ", "
End Function

I'll suggest you post more of your relevant code (that calls this function). You've stated that last_name is a String, but it appears that may not be the case. Step through your code line by line and ensure that this is actually the case.

The answer by @sbk is the way we should do it in spring-boot environment (apart from @Value("${classpath*:})), in my opinion. But in my scenario it was not working if the execute from standalone jar..may be I did something wrong.

But this can be another way of doing this,

InputStream is = this.getClass().getClassLoader().getResourceAsStream(<relative path of the resource from resource directory>);

If you also want it to be a command you can reference without remembering the arguments, you could simply alias it:

alias df-gb='df -BG'

So if you type:

df-gb

into a terminal, you'll get your intended output of the disk usage in GB.

EDIT: or even use just df -h to get it in a standard, human readable format.

I found this https://typescriptbcl.codeplex.com/SourceControl/latest

here is the Guid version they have in case the link does not work later.

module System {
    export class Guid {
        constructor (public guid: string) {
            this._guid = guid;
        }

        private _guid: string;

        public ToString(): string {
            return this.guid;
        }

        // Static member
        static MakeNew(): Guid {
            var result: string;
            var i: string;
            var j: number;

            result = "";
            for (j = 0; j < 32; j++) {
                if (j == 8 || j == 12 || j == 16 || j == 20)
                    result = result + '-';
                i = Math.floor(Math.random() * 16).toString(16).toUpperCase();
                result = result + i;
            }
            return new Guid(result);
        }
    }
}

Whenever I see addClass and removeClass I think why not just use toggleClass. In this case we can remove the .clickable class to avoid event bubbling, and to avoid the event from being fired on everything we click inside of the .clickable div.

$(document).on("click", ".close_button", function () { 
    $(this).closest(".grown").toggleClass("spot grown clickable");
});  

$(document).on("click", ".clickable", function () {
    $(this).toggleClass("spot grown clickable");
}); 

I also recommend a parent wrapper for your .clickable divs instead of using the document. I am not sure how you are adding them dynamically so didn't want to assume your layout for you.

Happy Coding :)

We know that video ID is 11 chars length and can be preceded by v= or vi= or v/ or vi/ or youtu.be/. So the simplest way to do this:

<?php
$youtube = 'http://youtube.com/v/dQw4w9WgXcQ?feature=youtube_gdata_player
http://youtube.com/vi/dQw4w9WgXcQ?feature=youtube_gdata_player
http://youtube.com/?v=dQw4w9WgXcQ&feature=youtube_gdata_player
http://www.youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player
http://youtube.com/?vi=dQw4w9WgXcQ&feature=youtube_gdata_player
http://youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player
http://youtube.com/watch?vi=dQw4w9WgXcQ&feature=youtube_gdata_player
http://youtu.be/dQw4w9WgXcQ?feature=youtube_gdata_player';

preg_match_all("#(?<=v=|v\/|vi=|vi\/|youtu.be\/)[a-zA-Z0-9_-]{11}#", $youtube, $matches);

var_dump($matches[0]);

And output:

array(8) {
  [0]=>
  string(11) "dQw4w9WgXcQ"
  [1]=>
  string(11) "dQw4w9WgXcQ"
  [2]=>
  string(11) "dQw4w9WgXcQ"
  [3]=>
  string(11) "dQw4w9WgXcQ"
  [4]=>
  string(11) "dQw4w9WgXcQ"
  [5]=>
  string(11) "dQw4w9WgXcQ"
  [6]=>
  string(11) "dQw4w9WgXcQ"
  [7]=>
  string(11) "dQw4w9WgXcQ"
}

Every managed exe has a an entry point which can be seen when if you load your code to ILDASM. The Entry Point is specified in the CLR headed and would look something like this.

You can also do it via powershell using SET STATISTICS XML ON to get the actual plan. I've written it so that it merges multi-statement plans into one plan;

I would counsel against using if ($hash{$key}) since it will not do what you expect if the key exists but its value is zero or empty.

The solution for those who cannot or do not want to wrap the table in a div (e.g. if the HTML is generated from Markdown) but still want to have scrollbars:

table {_x000D_
  display: block;_x000D_
  max-width: -moz-fit-content;_x000D_
  max-width: fit-content;_x000D_
  margin: 0 auto;_x000D_
  overflow-x: auto;_x000D_
  white-space: nowrap;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <td>Especially on mobile, a table can easily become wider than the viewport.</td>_x000D_
    <td>Using the right CSS, you can get scrollbars on the table without wrapping it.</td>_x000D_
  </tr>_x000D_
</table>_x000D_
_x000D_
<table>_x000D_
  <tr>_x000D_
    <td>A centered table.</td>_x000D_
  </tr>_x000D_
</table>

Explanation: display: block; makes it possible to have scrollbars. By default (and unlike tables), blocks span the full width of the parent element. This can be prevented with max-width: fit-content;, which allows you to still horizontally center tables with less content using margin: 0 auto;. white-space: nowrap; is optional (but useful for this demonstration).

This also works

SELECT *
FROM tableB
WHERE ID NOT IN (
  SELECT ID FROM tableA
);

You could use the common_schema and use the tokenize function. For more information about this, follow the links. Your code the would end up like:

call tokenize(name, ' ');

However, be aware that a space is not a reliable separator for first and last name. E.g. In Spain it is common to have two last names.

Another Solution in Case You Don't Have Control Over Dynamic Content

This works if you didn't load your element through a directive (ie. like in the example in the commented jsfiddles).

Wrap up Your Content

Wrap your content in a div so that you can select it if you are using JQuery. You an also opt to use native javascript to get your element.

<div class="selector">
    <grid-filter columnname="LastNameFirstName" gridname="HomeGrid"></grid-filter>
</div>

Use Angular Injector

You can use the following code to get a reference to $compile if you don't have one.

$(".selector").each(function () {
    var content = $(this);
    angular.element(document).injector().invoke(function($compile) {
        var scope = angular.element(content).scope();
        $compile(content)(scope);
    });
});

Summary

The original post seemed to assume you had a $compile reference handy. It is obviously easy when you have the reference, but I didn't so this was the answer for me.

One Caveat of the previous code

If you are using a asp.net/mvc bundle with minify scenario you will get in trouble when you deploy in release mode. The trouble comes in the form of Uncaught Error: [$injector:unpr] which is caused by the minifier messing with the angular javascript code.

Here is the way to remedy it:

Replace the prevous code snippet with the following overload.

...
angular.element(document).injector().invoke(
[
    "$compile", function($compile) {
        var scope = angular.element(content).scope();
        $compile(content)(scope);
    }
]);
...

This caused a lot of grief for me before I pieced it together.

When you write the following line of code in TypeScript:

var SUCSS = {};

The type of SUCSS is inferred from the assignment (i.e. it is an empty object type).

You then go on to add a property to this type a few lines later:

SUCSS.fadeDiv = //...

And the compiler warns you that there is no property named fadeDiv on the SUCSS object (this kind of warning often helps you to catch a typo).

You can either... fix it by specifying the type of SUCSS (although this will prevent you from assigning {}, which doesn't satisfy the type you want):

var SUCSS : {fadeDiv: () => void;};

Or by assigning the full value in the first place and let TypeScript infer the types:

var SUCSS = {
    fadeDiv: function () {
        // Simplified version
        alert('Called my func');
    }
};

I went with the HTML5 local storage solution... All my links call a function which sets this before changing window.location:

localStorage.topper = document.body.scrollTop;

and each page has this in the body's onLoad:

  if(localStorage.topper > 0){ 
    window.scrollTo(0,localStorage.topper);
  }

As with many tasks in ggplot, the general strategy is to put what you'd like to add to the plot into a data frame in a way such that the variables match up with the variables and aesthetics in your plot. So for example, you'd create a new data frame like this:

dfTab <- as.data.frame(table(df))
colnames(dfTab)[1] <- "x"
dfTab$lab <- as.character(100 * dfTab$Freq / sum(dfTab$Freq))

So that the x variable matches the corresponding variable in df, and so on. Then you simply include it using geom_text:

ggplot(df) + geom_bar(aes(x,fill=x)) + 
    geom_text(data=dfTab,aes(x=x,y=Freq,label=lab),vjust=0) +
    opts(axis.text.x=theme_blank(),axis.ticks=theme_blank(),
        axis.title.x=theme_blank(),legend.title=theme_blank(),
        axis.title.y=theme_blank())

This example will plot just the percentages, but you can paste together the counts as well via something like this:

dfTab$lab <- paste(dfTab$Freq,paste("(",dfTab$lab,"%)",sep=""),sep=" ")

Note that in the current version of ggplot2, opts is deprecated, so we would use theme and element_blank now.

I have extended cletus proposed answer to working code example.

1. One ExecutorService (pes) accepts Producer tasks.
2. One ExecutorService (ces) accepts Consumer tasks.
3. Both Producer and Consumer shares BlockingQueue.
4. Multiple Producer tasks generates different numbers.
5. Any of Consumer tasks can consume number generated by Producer

Code:

import java.util.concurrent.*;

public class ProducerConsumerWithES {
    public static void main(String args[]){
         BlockingQueue<Integer> sharedQueue = new LinkedBlockingQueue<Integer>();

         ExecutorService pes = Executors.newFixedThreadPool(2);
         ExecutorService ces = Executors.newFixedThreadPool(2);

         pes.submit(new Producer(sharedQueue,1));
         pes.submit(new Producer(sharedQueue,2));
         ces.submit(new Consumer(sharedQueue,1));
         ces.submit(new Consumer(sharedQueue,2));
         // shutdown should happen somewhere along with awaitTermination
         / * https://stackoverflow.com/questions/36644043/how-to-properly-shutdown-java-executorservice/36644320#36644320 */
         pes.shutdown();
         ces.shutdown();
    }
}
class Producer implements Runnable {
    private final BlockingQueue<Integer> sharedQueue;
    private int threadNo;
    public Producer(BlockingQueue<Integer> sharedQueue,int threadNo) {
        this.threadNo = threadNo;
        this.sharedQueue = sharedQueue;
    }
    @Override
    public void run() {
        for(int i=1; i<= 5; i++){
            try {
                int number = i+(10*threadNo);
                System.out.println("Produced:" + number + ":by thread:"+ threadNo);
                sharedQueue.put(number);
            } catch (Exception err) {
                err.printStackTrace();
            }
        }
    }
}

class Consumer implements Runnable{
    private final BlockingQueue<Integer> sharedQueue;
    private int threadNo;
    public Consumer (BlockingQueue<Integer> sharedQueue,int threadNo) {
        this.sharedQueue = sharedQueue;
        this.threadNo = threadNo;
    }
    @Override
    public void run() {
        while(true){
            try {
                int num = sharedQueue.take();
                System.out.println("Consumed: "+ num + ":by thread:"+threadNo);
            } catch (Exception err) {
               err.printStackTrace();
            }
        }
    }   
}

output:

Produced:11:by thread:1
Produced:21:by thread:2
Produced:22:by thread:2
Consumed: 11:by thread:1
Produced:12:by thread:1
Consumed: 22:by thread:1

Consumed: 15:by thread:1

Note. If you don't need multiple Producers and Consumers, keep single Producer and Consumer. I have added multiple Producers and Consumers to showcase capabilities of BlockingQueue among multiple Producers and Consumers.

@RestController was provided since Spring 4.0.1. These controllers indicate that here @RequestMapping methods assume @ResponseBody semantics by default.

In earlier versions the similar functionality could be achieved by using below:

1. @RequestMapping coupled with @ResponseBody like @RequestMapping(value = "/abc", method = RequestMethod.GET, produces ="application/xml") public @ResponseBody MyBean fetch(){ return new MyBean("hi") }

2. <mvc:annotation-driven/> may be used as one of the ways for using JSON with Jackson or xml.

3. MyBean can be defined like

@XmlRootElement(name = "MyBean") @XmlType(propOrder = {"field2", "field1"}) public class MyBean{ field1 field2 .. //getter, setter }

4. @ResponseBody is treated as the view here among MVC and it is dispatched directly instead being dispatched from Dispatcher Servlet and the respective converters convert the response in the related format like text/html, application/xml, application/json .

However, the Restcontroller is already coupled with ResponseBody and the respective converters. Secondly, here, since instead of converting the responsebody, it is automatically converted to http response.

I wrote the following class to get YouTube video duration using the YouTube API v3 (it returns thumbnails as well):

class Youtube
{
    static $api_key = '<API_KEY>';
    static $api_base = 'https://www.googleapis.com/youtube/v3/videos';
    static $thumbnail_base = 'https://i.ytimg.com/vi/';

    // $vid - video id in youtube
    // returns - video info
    public static function getVideoInfo($vid)
    {
        $params = array(
            'part' => 'contentDetails',
            'id' => $vid,
            'key' => self::$api_key,
        );

        $api_url = Youtube::$api_base . '?' . http_build_query($params);
        $result = json_decode(@file_get_contents($api_url), true);

        if(empty($result['items'][0]['contentDetails']))
            return null;
        $vinfo = $result['items'][0]['contentDetails'];

        $interval = new DateInterval($vinfo['duration']);
        $vinfo['duration_sec'] = $interval->h * 3600 + $interval->i * 60 + $interval->s;

        $vinfo['thumbnail']['default']       = self::$thumbnail_base . $vid . '/default.jpg';
        $vinfo['thumbnail']['mqDefault']     = self::$thumbnail_base . $vid . '/mqdefault.jpg';
        $vinfo['thumbnail']['hqDefault']     = self::$thumbnail_base . $vid . '/hqdefault.jpg';
        $vinfo['thumbnail']['sdDefault']     = self::$thumbnail_base . $vid . '/sddefault.jpg';
        $vinfo['thumbnail']['maxresDefault'] = self::$thumbnail_base . $vid . '/maxresdefault.jpg';

        return $vinfo;
    }
}

Please note that you'll need API_KEY to use the YouTube API:

1. Create a new project here: https://console.developers.google.com/project
2. Enable "YouTube Data API" under "APIs & auth" -> APIs
3. Create a new server key under "APIs & auth" -> Credentials

https://support.procore.com/faq/what-is-the-difference-between-sp-and-idp-initiated-sso

There is much more to this but this is a high level overview on which is which.

Procore supports both SP- and IdP-initiated SSO:

Identity Provider Initiated (IdP-initiated) SSO. With this option, your end users must log into your Identity Provider's SSO page (e.g., Okta, OneLogin, or Microsoft Azure AD) and then click an icon to log into and open the Procore web application. To configure this solution, see Configure IdP-Initiated SSO for Microsoft Azure AD, Configure Procore for IdP-Initated Okta SSO, or Configure IdP-Initiated SSO for OneLogin. OR Service Provider Initiated (SP-initiated) SSO. Referred to as Procore-initiated SSO, this option gives your end users the ability to sign into the Procore Login page and then sends an authorization request to the Identify Provider (e.g., Okta, OneLogin, or Microsoft Azure AD). Once the IdP authenticates the user's identify, the user is logged into Procore. To configure this solution, see Configure Procore-Initiated SSO for Microsoft Azure Active Directory, Configure Procore-Initiated SSO for Okta, or Configure Procore-Initiated SSO for OneLogin.

The easiest way that I found to recover a lost commit (that only exists on github and not locally) is to create a new branch that includes this commit.

1. Have the commit open (url like: github.com/org/repo/commit/long-commit-sha)
2. Click "Browse Files" on the top right
3. Click the dropdown "Tree: short-sha..." on the top left
4. Type in a new branch name
5. git pull the new branch down to local

System.String is a reference type so you don't need to do anything like

Nullable<string>

It already has a null value (the null reference):

string x = null; // No problems here

So, I'm coming late to the party, but here's my two cents - philosophically adding to Colin Hebert's answer.

At a high level your question deals with the difference between objects and types. While there are many cars (objects), there is only one Car class (type). Declaring something as static means that you are operating in the "type" space. There is only one. The top-level class keyword already defines a type in the "type" space. As a result "public static class Car" is redundant.

Swift 5

if let url = URL(string: "https://www.google.com") {
    UIApplication.shared.open(url)
}

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

Using timer threads-

from threading import Timer,Thread,Event


class perpetualTimer():

   def __init__(self,t,hFunction):
      self.t=t
      self.hFunction = hFunction
      self.thread = Timer(self.t,self.handle_function)

   def handle_function(self):
      self.hFunction()
      self.thread = Timer(self.t,self.handle_function)
      self.thread.start()

   def start(self):
      self.thread.start()

   def cancel(self):
      self.thread.cancel()

def printer():
    print 'ipsem lorem'

t = perpetualTimer(5,printer)
t.start()

this can be stopped by t.cancel()

Here is a runnable example using the mentioned indeterminate attribute:

const indeterminates = document.getElementsByClassName('indeterminate');_x000D_
indeterminates['0'].indeterminate  = true;

<form>_x000D_
  <div>_x000D_
    <input type="checkbox" checked="checked" />True_x000D_
  </div>_x000D_
  <div>_x000D_
    <input type="checkbox" />False_x000D_
  </div>_x000D_
  <div>_x000D_
    <input type="checkbox" class="indeterminate" />Indeterminate_x000D_
  </div>_x000D_
</form>

Just run the code snippet to see how it looks like.

There is an old plugin called HEX Editor here.

According to this question on Super User it does not work on newer versions of Notepad++ and might have some stability issues, but it still could be useful depending on your needs.

Find the <SHA#> for the commit you want to go. You can find it in github or by typing git log or git reflog show at the command line and then do git reset --hard <SHA#>

Why just trying to use css hack to do what 1 line of HTML do the job. And why not to use semantic html tu put break to return to the line?

Fo me is realy better to use :

<br style="clear:both" />

And if you don't want any style in your html you just have to use class for your break and put .clear { clear:both; } in your CSS.

Advantage of this:

• Semantic use of html for return to the line
• If no CSS load it will be working
• No need extra CSS code and Hack
• no need to simulate the br with CSS, it's already exist in HTML

Based on the solution of @Roman, you can set multiple values:

update users as u set -- postgres FTW
  email = u2.email,
  first_name = u2.first_name,
  last_name = u2.last_name
from (values
  (1, '[email protected]', 'Hollis', 'O\'Connell'),
  (2, '[email protected]', 'Robert', 'Duncan')
) as u2(id, email, first_name, last_name)
where u2.id = u.id;

'Command + M' for OSX is working for me.

The "friendly PIL fork" Pillow works on Python 2 and 3. Check out the Github project for support matrix and so on.

I use a generic query I call "dump" (why? I don't know) that looks like this:

SET NEWPAGE NONE
SET PAGESIZE 0
SET SPACE 0
SET LINESIZE 16000
SET ECHO OFF
SET FEEDBACK OFF
SET VERIFY OFF
SET HEADING OFF
SET TERMOUT OFF
SET TRIMOUT ON
SET TRIMSPOOL ON
SET COLSEP |

spool &1..txt

@@&1

spool off
exit

I then call SQL*Plus passing the actual SQL script I want to run as an argument:

sqlplus -S user/password@database @dump.sql my_real_query.sql

The result is written to a file

my_real_query.sql.txt

.

Oracle will try to recompile invalid objects as they are referred to. Here the trigger is invalid, and every time you try to insert a row it will try to recompile the trigger, and fail, which leads to the ORA-04098 error.

You can select * from user_errors where type = 'TRIGGER' and name = 'NEWALERT' to see what error(s) the trigger actually gets and why it won't compile. In this case it appears you're missing a semicolon at the end of the insert line:

INSERT INTO Users (userID, firstName, lastName, password)
VALUES ('how', 'im', 'testing', 'this trigger')

So make it:

CREATE OR REPLACE TRIGGER newAlert
AFTER INSERT OR UPDATE ON Alerts
  BEGIN
        INSERT INTO Users (userID, firstName, lastName, password)
        VALUES ('how', 'im', 'testing', 'this trigger');
  END;           
/

If you get a compilation warning when you do that you can do show errors if you're in SQL*Plus or SQL Developer, or query user_errors again.

Of course, this assumes your Users tables does have those column names, and they are all varchar2... but presumably you'll be doing something more interesting with the trigger really.

I used Mercury/32 and Pegasus Mail to get the mail() functional. It works great too as a mail server if you want an email address ending with your domain name.

Get-Content has bad performance; it tries to read the file into memory all at once.

C# (.NET) file reader reads each line one by one

Best Performace

foreach($line in [System.IO.File]::ReadLines("C:\path\to\file.txt"))
{
       $line
}

Or slightly less performant

[System.IO.File]::ReadLines("C:\path\to\file.txt") | ForEach-Object {
       $_
}

The foreach statement will likely be slightly faster than ForEach-Object (see comments below for more information).

static void Main(string[] args)
{
    long blah = 20948230498204;
    Console.WriteLine(blah.ToString().Length);
}

$array = 1..5 | foreach { $false }

I had to do all of the following to completely remove it:

outline-style: none;
box-shadow: none;
border-color: transparent;

Example:

  border-radius: 20px;_x000D_
  padding: 20px;_x000D_
}_x000D_
_x000D_
.no-focusborder:focus {_x000D_
  outline-style: none;_x000D_
  box-shadow: none;_x000D_
  border-color: transparent;_x000D_
  background-color: black;_x000D_
  color: white;_x000D_
}

<p>Click in the white space, then press the "Tab" key.</p>_x000D_
<button>Button 1 (unchanged)</button>_x000D_

To get the current time in the local timezone as a naive datetime object:

from datetime import datetime
naive_dt = datetime.now()

If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).

To get the current time in UTC as a naive datetime object:

naive_utc_dt = datetime.utcnow()

To get the current time as an aware datetime object in Python 3.3+:

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time

To get the current time in the given time zone from the tz database:

import pytz

tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)

It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.

WHERE MyColumn = COALESCE(@value,MyColumn) 

• If @value is NULL, it will compare MyColumn to itself, ignoring @value = no where clause.

• IF @value has a value (NOT NULL) it will compare MyColumn to @value.

Reference: COALESCE (Transact-SQL).

None of these answers properly handle tabs, newlines, carriage returns, and some don't handle extended ASCII and unicode. This will KEEP tabs & newlines, but remove control characters and anything out of the ASCII set. Click "Run this code snippet" button to test. There is some new javascript coming down the pipe so in the future (2020+?) you may have to do \u{FFFFF} but not yet

console.log("line 1\nline2 \n\ttabbed\nF??^?¯?^??????????????l????~¨??????_??????a?????"????????????v?¯?????i????o?????????????????????".replace(/[\x00-\x08\x0E-\x1F\x7F-\uFFFF]/g, ''))

This is working in each IE, Firefox and Chrome's latest versions.

$(document).ready(function(){
        $('#whole').bind('DOMMouseScroll mousewheel', function(e){
            if(e.originalEvent.wheelDelta > 0 || e.originalEvent.detail < 0) {
                alert("up");
            }
            else{
                alert("down");
            }
        });
    });

Handling database versions is very important part of application development. I assume that you already have class AppDbHelper extending SQLiteOpenHelper. When you extend it you will need to implement onCreate and onUpgrade method.

1. When onCreate and onUpgrade methods called

   • onCreate called when app newly installed.
   • onUpgrade called when app updated.

2. Organizing Database versions I manage versions in a class methods. Create implementation of interface Migration. E.g. For first version create MigrationV1 class, second version create MigrationV1ToV2 (these are my naming convention)

    public interface Migration {
        void run(SQLiteDatabase db);//create tables, alter tables
    }

Example migration:

public class MigrationV1ToV2 implements Migration{
      public void run(SQLiteDatabase db){
        //create new tables
        //alter existing tables(add column, add/remove constraint)
        //etc.
     }
   }

3. Using Migration classes

onCreate: Since onCreate will be called when application freshly installed, we also need to execute all migrations(database version updates). So onCreate will looks like this:

public void onCreate(SQLiteDatabase db){
        Migration mV1=new MigrationV1();
       //put your first database schema in this class
        mV1.run(db);
        Migration mV1ToV2=new MigrationV1ToV2();
        mV1ToV2.run(db);
        //other migration if any
  }

onUpgrade: This method will be called when application is already installed and it is updated to new application version. If application contains any database changes then put all database changes in new Migration class and increment database version.

For example, lets say user has installed application which has database version 1, and now database version is updated to 2(all schema updates kept in MigrationV1ToV2). Now when application upgraded, we need to upgrade database by applying database schema changes in MigrationV1ToV2 like this:

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    if (oldVersion < 2) {
        //means old version is 1
        Migration migration = new MigrationV1ToV2();
        migration.run(db);
    }
    if (oldVersion < 3) {
        //means old version is 2
    }
}

Note: All upgrades (mentioned in onUpgrade) in to database schema should be executed in onCreate

I noticed that Visual Studio's built-in error detector kind of gets goofy if you try to do this:

var intvar = @(ViewBag.someNumericValue);

Because @(ViewBag.someNumericValue) has the potential to evaluate to nothing, which would lead to the following erroneous JavaScript being generated:

var intvar = ;

If you're certain that someNemericValue will be set to a valid numeric data type, you can avoid having Visual Studio warnings by doing the following:

var intvar = Number(@(ViewBag.someNumericValue));

This might generate the following sample:

var intvar = Number(25.4);

And it works for negative numbers. In the event that the item isn't in your viewbag, Number() evaluates to 0.

No more Visual Studio warnings! But make sure the value is set and is numeric, otherwise you're opening doors to possible JavaScript injection attacks or run time errors.

Tried all the solutions above but none of them worked for me. What did work was I uninstalling .NET versions > 4.5, including all its multilingual versions; Eventually I added newer (English only) versions piece by piece. Right now versions installed on my system is this:

• 2.0
• 3.0
• 3.5 4
• 4.5
• 4.5.1
• 4.5.2
• 4.6
• 4.6.1

And its still working at this point. I'm afraid to install 4.6.2 because it might mess everything up.

So I could only speculate that either 4.6.2 or all those non-English versions were messing up my configuration.

For me:

It was Eclipse v4.5 (Mars) which did not support Java SE 7, so I added Java SE 8. It worked.

Standard Python dictionaries are inherently unordered, so what you're asking to do doesn't really make sense.

If you really, really know what you're doing, use

value_at_index = dic.values()[index]

Bear in mind that adding or removing an element can potentially change the index of every other element.

Everyone is saying to use isset() - which will probably work for you.

However, it's important that you understand the difference between

$_POST['x'] = NULL; and $_POST['x'] = '';

isset($_POST['x']) will return false on the first example, but will return true on the second one even though if you tried to print either one, both would return a blank value.

If your $_POST is coming from a user-inputted field/form and is left blank, I BELIEVE (I am not 100% certain on this though) that the value will be "" but NOT NULL.

Even if that assumption is incorrect (someone please correct me if I'm wrong!) the above is still good to know for future use.

Yes, see "Loading Page Fragments" on http://api.jquery.com/load/.

In short, you add the selector after the URL. For example:

$('#result').load('ajax/test.html #container');

The following code shows how to read values from an HTML form. As @pimvdb said you need to use the request.on('data'...) to capture the contents of the body.

const http = require('http')

const server = http.createServer(function(request, response) {
  console.dir(request.param)

  if (request.method == 'POST') {
    console.log('POST')
    var body = ''
    request.on('data', function(data) {
      body += data
      console.log('Partial body: ' + body)
    })
    request.on('end', function() {
      console.log('Body: ' + body)
      response.writeHead(200, {'Content-Type': 'text/html'})
      response.end('post received')
    })
  } else {
    console.log('GET')
    var html = `
            <html>
                <body>
                    <form method="post" action="http://localhost:3000">Name:

                    </form>
                </body>
            </html>`
    response.writeHead(200, {'Content-Type': 'text/html'})
    response.end(html)
  }
})

const port = 3000
const host = '127.0.0.1'
server.listen(port, host)
console.log(`Listening at http://${host}:${port}`)

If you use something like Express.js and Bodyparser then it would look like this since Express will handle the request.body concatenation

var express = require('express')
var fs = require('fs')
var app = express()

app.use(express.bodyParser())

app.get('/', function(request, response) {
  console.log('GET /')
  var html = `
    <html>
        <body>
            <form method="post" action="http://localhost:3000">Name: 
                <input type="text" name="name" />
                <input type="submit" value="Submit" />
            </form>
        </body>
    </html>`
  response.writeHead(200, {'Content-Type': 'text/html'})
  response.end(html)
})

app.post('/', function(request, response) {
  console.log('POST /')
  console.dir(request.body)
  response.writeHead(200, {'Content-Type': 'text/html'})
  response.end('thanks')
})

port = 3000
app.listen(port)
console.log(`Listening at http://localhost:${port}`)

The below seems to work. The enter event handles the tabbing to the control and the MouseDown works when the control is clicked.

    private ########### void textBox1_Enter(object sender, EventArgs e)
    {
        textBox1.SelectAll();
    }

    private void textBox1_MouseDown(object sender, MouseEventArgs e)
    {
        if (textBox1.Focused)
            textBox1.SelectAll();
    }

        private Integer value;

        private Right(Integer value) {
            this.value = value;
        }

        // Reverse lookup Right for getting a Key from it's values
        private static final Map<Integer, Right> lookup = new HashMap<Integer, Right>();
        static {
            for (Right item : Right.values())
                lookup.put(item.getValue(), item);
        }

        public Integer getValue() {
            return value;
        }

        public static Right getKey(Integer value) {
            return lookup.get(value);
        }

        return Right.getKey(this.rightId);

        this.rightId = right.getValue();
    }

}

(This method works for ifs, multiple nested loops and other constructs that you can't break from easily.)

Wrap the code in its own function. Instead of break, use return.

Example:

def some_function():
    if condition_a:
        # do something and return early
        ...
        return
    ...
    if condition_b:
        # do something else and return early
        ...
        return
    ...
    return

if outer_condition:
    ...
    some_function()
    ...

Spending some time coming up with an SKU naming strategy can help you. You’ll be able to make it easy for team members to read and understand what each SKU represents. Use a value that is meaningful to your organization.

Ultimately, your SKU is a way to record important product information, so the more straightforward it is, the better for everyone.

Sticking to alphanumeric SKUs and substituting “-” or “_” for space is always the safest and best bet.

E.g. Your app name: Social Point, Submit year: 2020 = Your SKU is: Social_Point_2020

You want to use the built-in browser HTML strip for that instead of applying yourself a regexp. It is more secure since the ever green browser does the work for you.

angular.module('myApp.filters', []).
  filter('htmlToPlaintext', function() {
    return function(text) {
      return stripHtml(text);
    };
  }
);

var stripHtml = (function () {
  var tmpEl = $document[0].createElement("DIV");
  function strip(html) {
    if (!html) {
      return "";
    }
    tmpEl.innerHTML = html;
    return tmpEl.textContent || tmpEl.innerText || "";
  }
  return strip;
}());

The reason for wrapping it in an self-executing function is for reusing the element creation.

See the MSDN getch docs. Specifically:

The _getch and_getwch functions read a single character from the console without echoing the character. None of these functions can be used to read CTRL+C. When reading a function key or an arrow key, each function must be called twice; the first call returns 0 or 0xE0, and the second call returns the actual key code.

The Python function returns a character. you can use ord() to get an integer value you can test, for example keycode = ord(msvcrt.getch()).

So if you read an 0x00 or 0xE0, read it a second time to get the key code for an arrow or function key. From experimentation, 0x00 precedes F1-F10 (0x3B-0x44) and 0xE0 precedes arrow keys and Ins/Del/Home/End/PageUp/PageDown.

You can also try:

INSERT IGNORE
  INTO table_1 
SELECT *
  FROM table_2
     ;

which allows those rows in table_1 to supersede those in table_2 that have a matching primary key, while still inserting rows with new primary keys.

Alternatively,

REPLACE
   INTO table_1
 SELECT *
   FROM table_2
      ;

will update those rows already in table_1 with the corresponding row from table_2, while inserting rows with new primary keys.

Go to File-> Project Structure-> Libraries and click green "+" to add the directory folder that has the JARs to CLASSPATH. Everything in that folder will be added to CLASSPATH.

Update:

It's 2018. It's a better idea to use a dependency manager like Maven and externalize your dependencies. Don't add JAR files to your project in a /lib folder anymore.

I was cleaning up warnings and messages and see that VS does warn about it: Validation (ASP.Net): Attribute 'OnClick' is not a valid attribute of element 'CheckBox'. Use the html input control to specify a client side handler and then you won't get the extra span tag and the two elements.

Using the CellFormating event and the e argument:

If CInt(e.Value) < 5 Then e.CellStyle.ForeColor = Color.Red

A solution that works:

Wrap the part of the document that needs this modified behavior with the code provided below. In my case the portion to wrap is a \part{} and some text following it.

\makeatletter\@openrightfalse
\part{Whatever}

Some text

\chapter{Foo}
\@openrighttrue\makeatother 

The wrapped portion should also include the chapter at the beginning of which this behavior needs to stop. Otherwise LaTeX may generate an empty page before this chapter.

Another way to phrase the same idea:

• If speeding up the CPU doesn't speed up your program, it may be I/O bound.

• If speeding up the I/O (e.g. using a faster disk) doesn't help, your program may be CPU bound.

(I used "may be" because you need to take other resources into account. Memory is one example.)

A simple regular expression would work

$string = preg_replace("/,$/", "", $string)

If you have tried installing via the official docker-compose page, where you need to download the binary using curl:

curl -L https://github.com/docker/compose/releases/download/1.8.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

Then do not forget to add executable flag to the binary:

chmod +x /usr/local/bin/docker-compose

If docker-compose is installed using python-pip

sudo apt-get -y install python-pip
sudo pip install docker-compose

try using pip show --files docker-compose to see where it is installed.

If docker-compose is installed in user path, then try:

sudo "PATH=$PATH" docker-compose

As I see from your updated post, docker-compose is installed in user path /home/user/.local/bin and if this path is not in your local path $PATH, then try:

sudo "PATH=$PATH:/home/user/.local/bin" docker-compose

Finally I found the solution ... It's very easy

1. Go to the LAN settings (In Chrome : Tools -> Options -> Under the hood -> Change Proxy setting -> LAN Setting)

2. There will be a checkbox for "Bypass proxy server for local address"

3. Tick the checkbox.

Done!

On Mac/Apple: Chrome uses system preferences for localhost exclusion:

1. Go to System Preferences -> Network -> advanced -> Proxy settings

2. Add 'localhost' at the bottom where it says: 'ignore proxy settings for these hosts and domains' (Exceptions are separated by a comma)

Add zIndex property to dialog object:

$(elm).dialog(
 zIndex: 10000
);

In case you develop applications for Android you should try out the TimingLogger class.
Take a look at these articles describing the usage of the TimingLogger helper class:

• Measuring performance in the Android SDK (27.09.2010)
• Discovering the Android API - Part 1 (03.01.2017)

There are several steps when using OpenSSL. You must have an SSL certificate made which can contain the certificate with the private key be sure to specify the exact location of the certificate (this example has it in the root). There are a lot of good tutorials out there.

• Some documentation and tools from HP (see chapter 2)
• Command line for OpenSSL

Some includes:

#include <openssl/applink.c>
#include <openssl/bio.h>
#include <openssl/ssl.h>
#include <openssl/err.h>

You will need to initialize OpenSSL:

void InitializeSSL()
{
    SSL_load_error_strings();
    SSL_library_init();
    OpenSSL_add_all_algorithms();
}

void DestroySSL()
{
    ERR_free_strings();
    EVP_cleanup();
}

void ShutdownSSL()
{
    SSL_shutdown(cSSL);
    SSL_free(cSSL);
}

Now for the bulk of the functionality. You may want to add a while loop on connections.

int sockfd, newsockfd;
SSL_CTX *sslctx;
SSL *cSSL;

InitializeSSL();
sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd< 0)
{
    //Log and Error
    return;
}
struct sockaddr_in saiServerAddress;
bzero((char *) &saiServerAddress, sizeof(saiServerAddress));
saiServerAddress.sin_family = AF_INET;
saiServerAddress.sin_addr.s_addr = serv_addr;
saiServerAddress.sin_port = htons(aPortNumber);

bind(sockfd, (struct sockaddr *) &serv_addr, sizeof(serv_addr));

listen(sockfd,5);
newsockfd = accept(sockfd, (struct sockaddr *) &cli_addr, &clilen);

sslctx = SSL_CTX_new( SSLv23_server_method());
SSL_CTX_set_options(sslctx, SSL_OP_SINGLE_DH_USE);
int use_cert = SSL_CTX_use_certificate_file(sslctx, "/serverCertificate.pem" , SSL_FILETYPE_PEM);

int use_prv = SSL_CTX_use_PrivateKey_file(sslctx, "/serverCertificate.pem", SSL_FILETYPE_PEM);

cSSL = SSL_new(sslctx);
SSL_set_fd(cSSL, newsockfd );
//Here is the SSL Accept portion.  Now all reads and writes must use SSL
ssl_err = SSL_accept(cSSL);
if(ssl_err <= 0)
{
    //Error occurred, log and close down ssl
    ShutdownSSL();
}

You are then able read or write using:

SSL_read(cSSL, (char *)charBuffer, nBytesToRead);
SSL_write(cSSL, "Hi :3\n", 6);

Update The SSL_CTX_new should be called with the TLS method that best fits your needs in order to support the newer versions of security, instead of SSLv23_server_method(). See: OpenSSL SSL_CTX_new description

TLS_method(), TLS_server_method(), TLS_client_method(). These are the general-purpose version-flexible SSL/TLS methods. The actual protocol version used will be negotiated to the highest version mutually supported by the client and the server. The supported protocols are SSLv3, TLSv1, TLSv1.1, TLSv1.2 and TLSv1.3.

I also get this error quite often.

I solve this by modifying the code (doing a very small change), saving it, then building the solution again.

The shortest code

ChromeDriver drv = new ChromeDriver();

drv.Navigate().GoToUrl("https://stackoverflow.com/questions/6229769/execute-javascript-using-selenium-webdriver-in-c-sharp");

drv.ExecuteScript("return alert(document.title);");

You can execute any shell command using the shelljs module

 const shell = require('shelljs')

 shell.exec('./path_to_your_file')

This worked in my case:

DecimalFormat df2 = new DecimalFormat("#.##");           
df2.setDecimalFormatSymbols(DecimalFormatSymbols.getInstance(Locale.ENGLISH));

sure,

just have to create a ".gitignore" on the home directory of your project and have to contain

*.swp

that's it

in one command

project-home-directory$ echo '*.swp' >> .gitignore

Open Google Maps using Intent with different Modes:

We can open Google Maps app using intent:

val gmmIntentUri = Uri.parse("google.navigation:q="+destintationLatitude+","+destintationLongitude + "&mode=b")
val mapIntent = Intent(Intent.ACTION_VIEW, gmmIntentUri)
mapIntent.setPackage("com.google.android.apps.maps")
startActivity(mapIntent)

Here, "mode=b" is for bicycle.

We can set driving, walking, and bicycling mode by using:

• d for driving
• w for walking
• b for bicycling

You can find more about intent with google maps here.

Note: If there is no route for the bicycle/car/walk then it will show you "Can't find the way there"

You can check my original answer here.

All the other solutions are creepy because they are from someone that arrogantly simply thinks that English is the only language in the world :)

All those solutions strip also diacritics like ç or à.

The perfect solution, as stated in PHP documentation, is simply:

$clear = strip_tags($des);

There's ImageJ, which boasts to be the

world's fastest pure Java image processing program

It can be used as a library in another application. It's architecture is not brilliant, but it does basic image processing tasks.

You don't necessarily need to make any changes to your code (nor to change the SUBSYSTEM type). If you wish, you also could simply pipe stdout and stderr to a console application (a Windows version of cat works well).

var settings = 
    JSON.parse(
        require('fs').readFileSync(
            require('path').resolve(
                __dirname, 
                'settings.json'),
            'utf8'));

To get the actual height of the Actionbar, you have to resolve the attribute actionBarSize at runtime.

TypedValue tv = new TypedValue();
context.getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true);
int actionBarHeight = getResources().getDimensionPixelSize(tv.resourceId);

chmod 400 /etc/ssh/* works for me.

In View

<select ng-model="boxmodel"><option ng-repeat="lst in list" value="{{lst.id}}">{{lst.name}}</option></select>

JS:

In side controller

 $scope.boxModel = 600;

I was having problem in Windows 7 with PHP 5.4.0 in command line, using Xampp 1.8.1 server. This is what i did:

1. Rename php.ini-production to php.ini (in C:\xampp\php\ folder)
2. Edit php.ini and uncomment extension_dir=ext.
3. Also uncomment extension=php_openssl.dll.

After that it worked fine.

The following script ensures that my_finalFunction runs after your page has been fully loaded with images, stylesheets and external content:

<script>

    document.addEventListener("load", my_finalFunction, false);

    function my_finalFunction(e) {
        /* things to do after all has been loaded */
    }

</script>

A good explanation is provided by kirupa on running your code at the right time, see https://www.kirupa.com/html5/running_your_code_at_the_right_time.htm.

you have to call a function before it can return anything.

function mainFunction() {
      function subFunction() {
            var str = "foo";
            return str;
      }
      return subFunction();
}

var test = mainFunction();
alert(test);

Or:

function mainFunction() {
      function subFunction() {
            var str = "foo";
            return str;
      }
      return subFunction;
}

var test = mainFunction();
alert( test() );

for your actual code. The return should be outside, in the main function. The callback is called somewhere inside the getLocations method and hence its return value is not recieved inside your main function.

function reverseGeocode(latitude,longitude){
    var address = "";
    var country = "";
    var countrycode = "";
    var locality = "";

    var geocoder = new GClientGeocoder();
    var latlng = new GLatLng(latitude, longitude);

    geocoder.getLocations(latlng, function(addresses) {
     address = addresses.Placemark[0].address;
     country = addresses.Placemark[0].AddressDetails.Country.CountryName;
     countrycode = addresses.Placemark[0].AddressDetails.Country.CountryNameCode;
     locality = addresses.Placemark[0].AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.LocalityName;
    });   
    return country
   }

Local storage can store up to 5mb offline data, whereas session can also store up to 5 mb data. But cookies can store only 4kb data in text format.

LOCAl and Session storage data in JSON format, thus easy to parse. But cookies data is in string format.

I think this way is easy:

>>> bytes_data = [112, 52, 52]
>>> "".join(map(chr, bytes_data))
'p44'

In C++, there is only a subtle difference. It's a holdover from C, in which it makes a difference.

The C language standard (C89 §3.1.2.3, C99 §6.2.3, and C11 §6.2.3) mandates separate namespaces for different categories of identifiers, including tag identifiers (for struct/union/enum) and ordinary identifiers (for typedef and other identifiers).

If you just said:

struct Foo { ... };
Foo x;

you would get a compiler error, because Foo is only defined in the tag namespace.

You'd have to declare it as:

struct Foo x;

Any time you want to refer to a Foo, you'd always have to call it a struct Foo. This gets annoying fast, so you can add a typedef:

struct Foo { ... };
typedef struct Foo Foo;

Now struct Foo (in the tag namespace) and just plain Foo (in the ordinary identifier namespace) both refer to the same thing, and you can freely declare objects of type Foo without the struct keyword.

The construct:

typedef struct Foo { ... } Foo;

is just an abbreviation for the declaration and typedef.

Finally,

typedef struct { ... } Foo;

declares an anonymous structure and creates a typedef for it. Thus, with this construct, it doesn't have a name in the tag namespace, only a name in the typedef namespace. This means it also cannot be forward-declared. If you want to make a forward declaration, you have to give it a name in the tag namespace.

In C++, all struct/union/enum/class declarations act like they are implicitly typedef'ed, as long as the name is not hidden by another declaration with the same name. See Michael Burr's answer for the full details.

A common way to approach this is to add your own ForEach generic method on IEnumerable<T>. Here's the one we've got in MoreLINQ:

public static void ForEach<T>(this IEnumerable<T> source, Action<T> action)
{
    source.ThrowIfNull("source");
    action.ThrowIfNull("action");
    foreach (T element in source)
    {
        action(element);
    }
}

(Where ThrowIfNull is an extension method on any reference type, which does the obvious thing.)

It'll be interesting to see if this is part of .NET 4.0. It goes against the functional style of LINQ, but there's no doubt that a lot of people find it useful.

Once you've got that, you can write things like:

people.Where(person => person.Age < 21)
      .ForEach(person => person.EjectFromBar());

Swift version of Stephen Darlington's solution

UIView.beginAnimations(nil, context: nil)
UIView.setAnimationBeginsFromCurrentState(true)
UIView.setAnimationDuration(0.1)
// other animation properties

// set view properties
UIView.commitAnimations()

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

I'm a little confused about custom made completion handlers. In your example:

Say you have a download function to download a file from network,and want to be notified when download task has finished.

typealias CompletionHandler = (success:Bool) -> Void

func downloadFileFromURL(url: NSURL,completionHandler: CompletionHandler) {

    // download code.

    let flag = true // true if download succeed,false otherwise

    completionHandler(success: flag)
}

Your // download code will still be ran asynchronously. Why wouldn't the code go straight to your let flag = true and completion Handler(success: flag) without waiting for your download code to be finished?

For me worked no one of the solutions. But I found out that all the libraries of the support libraries were missing at my external libraries. And in other projects the AppCompatActivity was resolved without problems.

For me it worked to create a new project and copy all the stuff of the old src folder into the new project.

I don't know exact why, but if nothing works, it could be the last possibility. Just if someone has the same trouble as me.

iOS Icons

• Set AppIcon in Images.xcassets.
• Add 9 different size icons:
  • 29pt
  • 29pt*2
  • 29pt*3
  • 40pt*2
  • 40pt*3
  • 57pt
  • 57pt*2
  • 60pt*2
  • 60pt*3.

Images.xcassets will look like this:

Android Icons

• Put ic_launcher.png in folders [ProjectDirectory]/android/app/src/main/res/mipmap-*/.
  • 72*72 ic_launcher.png in mipmap-hdpi.
  • 48*48 ic_launcher.png in mipmap-mdpi.
  • 96*96 ic_launcher.png in mipmap-xhdpi.
  • 144*144 ic_launcher.png in mipmap-xxhdpi.
  • 192*192 ic_launcher.png in mipmap-xxxhdpi.

Update 2019 Android

The latest versions of react native also supports round icon. For this particular case, you have two choices:

A. Add round icons: In each mipmap folder, add additionally to the ic_launcher.png file also a round version called ic_launcher_round.png with the same size.

B. Remove round icons: Inside yourProjectFolder/android/app/src/main/AndroidManifest.xml remove the line android:roundIcon="@mipmap/ic_launcher_round"and save it.

Otherwhise the build throws an error.

Depending on the usage, there are several "correct" answers.

Since Java 5, the best way to do it is to use an enum:

public enum Foo {
   INSTANCE;
}

Pre Java 5, the most simple case is:

public final class Foo {

    private static final Foo INSTANCE = new Foo();

    private Foo() {
        if (INSTANCE != null) {
            throw new IllegalStateException("Already instantiated");
        }
    }

    public static Foo getInstance() {
        return INSTANCE;
    }

    public Object clone() throws CloneNotSupportedException{
        throw new CloneNotSupportedException("Cannot clone instance of this class");
    }
}

Let's go over the code. First, you want the class to be final. In this case, I've used the final keyword to let the users know it is final. Then you need to make the constructor private to prevent users to create their own Foo. Throwing an exception from the constructor prevents users to use reflection to create a second Foo. Then you create a private static final Foo field to hold the only instance, and a public static Foo getInstance() method to return it. The Java specification makes sure that the constructor is only called when the class is first used.

When you have a very large object or heavy construction code and also have other accessible static methods or fields that might be used before an instance is needed, then and only then you need to use lazy initialization.

You can use a private static class to load the instance. The code would then look like:

public final class Foo {

    private static class FooLoader {
        private static final Foo INSTANCE = new Foo();
    }

    private Foo() {
        if (FooLoader.INSTANCE != null) {
            throw new IllegalStateException("Already instantiated");
        }
    }

    public static Foo getInstance() {
        return FooLoader.INSTANCE;
    }
}

Since the line private static final Foo INSTANCE = new Foo(); is only executed when the class FooLoader is actually used, this takes care of the lazy instantiation, and is it guaranteed to be thread safe.

When you also want to be able to serialize your object you need to make sure that deserialization won't create a copy.

public final class Foo implements Serializable {

    private static final long serialVersionUID = 1L;

    private static class FooLoader {
        private static final Foo INSTANCE = new Foo();
    }

    private Foo() {
        if (FooLoader.INSTANCE != null) {
            throw new IllegalStateException("Already instantiated");
        }
    }

    public static Foo getInstance() {
        return FooLoader.INSTANCE;
    }

    @SuppressWarnings("unused")
    private Foo readResolve() {
        return FooLoader.INSTANCE;
    }
}

The method readResolve() will make sure the only instance will be returned, even when the object was serialized in a previous run of your program.

This worked for me.

just put under onCreate metode

Button button = (Button) findViewById(R.id.reload_btn);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            web.loadUrl( "javascript:window.location.reload( true )" );             
        }
    });

This is the code that can reload a website in a webView

web.loadUrl( "javascript:window.location.reload( true )" );  

\begin{tikzpicture}
    \tikzstyle{every node}=[font=\fontsize{30}{30}\selectfont]
\end{tikzpicture}

You should be using things like: KeyEvent.VK_UP instead of the actual code.

How are you wanting to refactor it? What is the goal of the refactoring?

Actually the correct answer to this is to just add the schema to your document, like so

<packages xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">

...and you're done :)

If the XSD is not already cached and unavailable, you can add it as follows from the NuGet console

Install-Package NuGet.Manifest.Schema -Version 2.0.0

Once this is done, as noted in a comment below, you may want to move it from your current folder to the official schema folder that is found in

%VisualStudioPath%\Xml\Schemas

This is working Oracle example but it should work in MySQL too.

You are missing smth - see IN after END Replace 'IN' with '=' sign for a single value.

SELECT empno, ename, job
  FROM scott.emp
 WHERE (CASE WHEN job = 'MANAGER' THEN '1'  
         WHEN job = 'CLERK'   THEN '2' 
         ELSE '0'  END) IN (1, 2)

$('<img src="'+ imgPath +'">').load(function() {
  $(this).width(some).height(some).appendTo('#some_target');
});

If you want to do for several images then:

function loadImage(path, width, height, target) {
    $('<img src="'+ path +'">').load(function() {
      $(this).width(width).height(height).appendTo(target);
    });
}

Use:

loadImage(imgPath, 800, 800, '#some_target');

If you can do this in java, try:

RuntimeMXBean

ManagementFactory

Example:

RuntimeMXBean runtimeMXBean = ManagementFactory.getRuntimeMXBean();
List<String> jvmArgs = runtimeMXBean.getInputArguments();
for (String arg : jvmArgs) {
    System.out.println(arg);
}

from scipy.optimize import fsolve

def double_solve(f1,f2,x0,y0):
    func = lambda x: [f1(x[0], x[1]), f2(x[0], x[1])]
    return fsolve(func,[x0,y0])

def n_solve(functions,variables):
    func = lambda x: [ f(*x) for f in functions]
    return fsolve(func, variables)

f1 = lambda x,y : x**2+y**2-1
f2 = lambda x,y : x-y

res = double_solve(f1,f2,1,0)
res = n_solve([f1,f2],[1.0,0.0])

You can access the timezone by the following script:

SELECT * FROM pg_timezone_names WHERE name = current_setting('TIMEZONE');

• current_setting('TIMEZONE') will give you Continent / Capital information of settings
• pg_timezone_names The view pg_timezone_names provides a list of time zone names that are recognized by SET TIMEZONE, along with their associated abbreviations, UTC offsets, and daylight-savings status.
• name column in a view (pg_timezone_names) is time zone name.

output will be :

name- Europe/Berlin, 
abbrev - CET, 
utc_offset- 01:00:00, 
is_dst- false

Add -recurse after the remove-item, also the -force parameter helps remove hidden files e.g.:

gci C:\temp\ -exclude *.svn-base,".svn" -recurse | %{ri $_ -force -recurse}

If you have access to a Gmail account on the phone then an easy way (in terms of minimal set up effort) is to mail the .apk file to that Gmail account.

If you then access that account from the native Gmail app on the phone it recognises that the attachment is an app and offers an "Install" button.

As per other responses this approach also requires that you have selected USB debugging on the device.

Try this - it is remarkably easy ;-)

Spring Boot already has support for profile based properties.

Simply add an application-[profile].properties file and specify the profiles to use using the spring.profiles.active property.

-Dspring.profiles.active=local

This will load the application.properties and the application-local.properties with the latter overriding properties from the first.

Check if have not set a open_basedir in php.ini or .htaccess of domain what you use. That will jail you in directory of your domain and php will get only access to execute inside this directory.

Pehaps...ok, very likely, I'm missing something, but why not just create an object type, say NSNumber, as a container to your non-object type variable, such as CGFloat?

CGFloat myFloat = 2.0; 
NSNumber *myNumber = [NSNumber numberWithFloat:myFloat];

[self performSelector:@selector(MyCalculatorMethod:) withObject:myNumber afterDelay:5.0];

If your VARCHAR column contains empty strings (which are not the same as NULL for PostgreSQL as you might recall) you will have to use something in the line of the following to set a default:

ALTER TABLE presales ALTER COLUMN code TYPE NUMERIC(10,0)
            USING COALESCE(NULLIF(code, '')::NUMERIC, 0);

For those of you using Centos (and perhaps other linux distibutions), you need to make sure that its FW (iptables) allows for port 80 or any other port you want.

For performing Unmarshall using JAXB:

1) Convert given XML to XSD(by yourself or by online convertor),

2) Create a JAXB project in eclipse,

3) Create XSD file and paste that converted XSD content in it,

4) Right click on **XSD file--> Generate--> JAXB Classes-->follow the instructions(this will create all nessasary .java files in src, i.e., one package-info, object factory and pojo class),

5) Create another .java file in src to operate unmarshall operation, and run it.

Happy Coding !!

Hey there's a useful tutorial on Dot Net pearls: http://www.dotnetperls.com/progressbar

In agreement with Peter, you need to use some amount of threading or the program will just hang, somewhat defeating the purpose.

Example that uses ProgressBar and BackgroundWorker: C#

using System.ComponentModel;
using System.Threading;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, System.EventArgs e)
        {
            // Start the BackgroundWorker.
            backgroundWorker1.RunWorkerAsync();
        }

        private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            for (int i = 1; i <= 100; i++)
            {
                // Wait 100 milliseconds.
                Thread.Sleep(100);
                // Report progress.
                backgroundWorker1.ReportProgress(i);
            }
        }

        private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            // Change the value of the ProgressBar to the BackgroundWorker progress.
            progressBar1.Value = e.ProgressPercentage;
            // Set the text.
            this.Text = e.ProgressPercentage.ToString();
        }
    }
} //closing here

 $("#contactForm").submit(function() {

    $.post(url, $.param($(this).serializeArray()), function(data) {

    });
 });

The idea ...To create a File object (api) in javaScript for images already present in the DOM :

<img src="../img/Products/fijRKjhudDjiokDhg1524164151.jpg">

var file = new File(['fijRKjhudDjiokDhg1524164151'],
                     '../img/Products/fijRKjhudDjiokDhg1524164151.jpg', 
                     {type:'image/jpg'});

// created object file
console.log(file);

Don't do that ! ... (but I did it anyway)

-> the console give a result similar as an Object File :

File(0) {name: "fijRKjokDhgfsKtG1527053050.jpg", lastModified: 1527053530715, lastModifiedDate: Wed May 23 2018 07:32:10 GMT+0200 (Paris, Madrid (heure d’été)), webkitRelativePath: "", size: 0, …}
lastModified:1527053530715
lastModifiedDate:Wed May 23 2018 07:32:10 GMT+0200 (Paris, Madrid (heure d’été)) {}
name:"fijRKjokDhgfsKtG1527053050.jpg"
size:0
type:"image/jpg"
webkitRelativePath:""__proto__:File

But the size of the object is wrong ...

Why i need to do that ?

For example to retransmit an image form already uploaded, during a product update, along with additional images added during the update

Creating colnames with iterating

df = pd.DataFrame(columns=['colname_' + str(i) for i in range(5)])
print(df)

# Empty DataFrame
# Columns: [colname_0, colname_1, colname_2, colname_3, colname_4]
# Index: []

to_html() operations

print(df.to_html())

# <table border="1" class="dataframe">
#   <thead>
#     <tr style="text-align: right;">
#       <th></th>
#       <th>colname_0</th>
#       <th>colname_1</th>
#       <th>colname_2</th>
#       <th>colname_3</th>
#       <th>colname_4</th>
#     </tr>
#   </thead>
#   <tbody>
#   </tbody>
# </table>

this seems working

print(type(df.to_html()))
# <class 'str'>

The problem is caused by

when you create df like this

df = pd.DataFrame(columns=COLUMN_NAMES)

it has 0 rows × n columns, you need to create at least one row index by

df = pd.DataFrame(columns=COLUMN_NAMES, index=[0])

now it has 1 rows × n columns. You are be able to add data. Otherwise its df that only consist colnames object(like a string list).

You can't serialize a collection of objects without specifying the expected types. You must pass the list of expected types to the constructor of XmlSerializer (the extraTypes parameter) :

List<object> list = new List<object>();
list.Add(new Foo());
list.Add(new Bar());

XmlSerializer xs = new XmlSerializer(typeof(object), new Type[] {typeof(Foo), typeof(Bar)});
using (StreamWriter streamWriter = System.IO.File.CreateText(fileName))
{
    xs.Serialize(streamWriter, list);
}

If all the objects of your list inherit from the same class, you can also use the XmlInclude attribute to specify the expected types :

[XmlInclude(typeof(Foo)), XmlInclude(typeof(Bar))]
public class MyBaseClass
{
}

use enumerate:

>>> l = ['a', 'b', 'c', 'd']
>>> for index, val in enumerate(l):
...    print "%d: %s" % (index, val)
... 
0: a
1: b
2: c
3: d

$session_data = array('username' =>"shashikant");
$this->session->set_userdata('logged_in', $session_data);

$this->session->unset_userdata('logged_in');

Use tr:first-child to take the first tr:

.category_table tr:first-child td {
    vertical-align: top;
}

If you have nested tables, and you don't want to apply styles to the inner rows, add some child selectors so only the top-level tds in the first top-level tr get the styles:

.category_table > tbody > tr:first-child > td {
    vertical-align: top;
}

This usually happen when you upgrade mysql. The installed mysql2 gem which was built on the old mysql libs cannot work with new libs. Just need to reinstall it.

Uninstall mysql2 with gem uninstall mysql2. Then install it with gem install mysql2

If you've copied a disk (vmdk file) from one machine to another and need to change a disk's UUID in the copy, you don't need to change the Machine UUID as has been suggested by another answer.

All you need to do is to assign a new UUID to the disk image:

VBoxManage internalcommands sethduuid your-box-disk2.vmdk
UUID changed to: 5d34479f-5597-4b78-a1fa-94e200d16bbb

and then replace the old UUID with the newly generated one in two places in your *.vbox file

<MediaRegistry>
  <HardDisks>
    <HardDisk uuid="{5d34479f-5597-4b78-a1fa-94e200d16bbb}" location="box-disk2.vmdk" format="VMDK" type="Normal"/>
  </HardDisks>

and in

    <AttachedDevice type="HardDisk" hotpluggable="false" port="0" device="0">
      <Image uuid="{5d34479f-5597-4b78-a1fa-94e200d16bbb}"/>
    </AttachedDevice>

It worked for me for VirtualBox ver. 5.1.8 running on Mac OS X El Capitan.

The subset command is not necessary. Just use data frame indexing

studentdata[studentdata$Drink == 'water',]

Read the warning from ?subset

This is a convenience function intended for use interactively. For programming it is better to use the standard subsetting functions like ‘[’, and in particular the non-standard evaluation of argument ‘subset’ can have unanticipated consequences.

int fib(int x) 
{
    if (x < 2)
      return x;
    else 
      return (fib(x - 1) + fib(x - 2));
}

You should be able to do the count on the purch variable:

purch.Count();

e.g.

var purch = from purchase in myBlaContext.purchases
select purchase;

purch.Count();

By my side, using Chrome navigator, I had to use DataView() to read an arrayBuffer

function _arrayBufferToBase64( tabU8A ) {
var binary = '';
let lecteur_de_donnees = new DataView(tabU8A);
var len = lecteur_de_donnees.byteLength;
var chaine = '';
var pos1;
for (var i = 0; i < len; i++) {
    binary += String.fromCharCode( lecteur_de_donnees.getUint8( i ) );
}
chaine = window.btoa( binary )
return chaine;}

Depending on your .NET version you could also use HttpClientExtensions.PostAsJsonAsync method.

A handy one-liner to delete branches other than 'master' from origin:

git branch --remotes | grep -v 'origin/master' | sed "s/origin\///" | xargs -i{foo} git push origin --delete {foo}

Be sure you understand the implications of running this before doing so!

Here is the general solution if you really only want the first key's value

Object firstKey = myHashMap.keySet().toArray()[0];
Object valueForFirstKey = myHashMap.get(firstKey);

String anotherPalindrome = "Niagara. O roar again!"; 
String roar = anotherPalindrome.substring(11, 15); 

You can also do like these

You've tagged this question with the ssl tag, and SSL is the answer. Curious.

I too was struggling with nested views in Angular.

Once I got a hold of ui-router I knew I was never going back to angular default routing functionality.

Here is an example application that uses multiple levels of views nesting

app.config(function ($stateProvider, $urlRouterProvider,$httpProvider) {
// navigate to view1 view by default
$urlRouterProvider.otherwise("/view1");

$stateProvider
    .state('view1', {
        url: '/view1',
        templateUrl: 'partials/view1.html',
        controller: 'view1.MainController'
    })
    .state('view1.nestedViews', {
        url: '/view1',
        views: {
            'childView1': { templateUrl: 'partials/view1.childView1.html' , controller: 'childView1Ctrl'},
            'childView2': { templateUrl: 'partials/view1.childView2.html', controller: 'childView2Ctrl' },
            'childView3': { templateUrl: 'partials/view1.childView3.html', controller: 'childView3Ctrl' }
        }
    })

    .state('view2', {
        url: '/view2',
    })

    .state('view3', {
        url: '/view3',
    })

    .state('view4', {
        url: '/view4',
    });
});

As it can be seen there are 4 main views (view1,view2,view3,view4) and view1 has 3 child views.

Should be xpath with not contains() method, //production[not(contains(category,'business'))]

CSS tricks have a good solution to target IE 11:

http://css-tricks.com/ie-10-specific-styles/

The .NET and Trident/7.0 are unique to IE so can be used to detect IE version 11.

The code then adds the User Agent string to the html tag with the attribute 'data-useragent', so IE 11 can be targeted specifically...

String coolString = "cool string";

byte[] byteArray = coolString.getBytes();

String reconstitutedString = new String(byteArray);

System.out.println(reconstitutedString);

That outputs "cool string" to the console.

It's pretty darn easy.

Swift 3.0

if let path = Bundle.main.path(forResource: "config", ofType: "plist") {
    let dict = NSDictionary(contentsOfFile: path)

    // use dictionary
}

The easiest way to do this in my opinion.

Example for Slack.... (use your own web address you generate there)...

curl -X POST -H "Content-type:application/json" --data "{\"text\":\"A New Program Has Just Been Posted!!!\"}" https://hooks.slack.com/services/T7M0PFD42/BAA6NK48Y/123123123123123

The more recent tidyverse way is to use the mutate_at function:

library(tidyverse)
library(magrittr)
set.seed(88)

data <- data.frame(matrix(sample(1:40), 4, 10, dimnames = list(1:4, LETTERS[1:10])))
cols <- c("A", "C", "D", "H")

data %<>% mutate_at(cols, funs(factor(.)))
str(data)
 $ A: Factor w/ 4 levels "5","17","18",..: 2 1 4 3   
 $ B: int  36 35 2 26
 $ C: Factor w/ 4 levels "22","31","32",..: 1 2 4 3
 $ D: Factor w/ 4 levels "1","9","16","39": 3 4 1 2
 $ E: int  3 14 30 38
 $ F: int  27 15 28 37
 $ G: int  19 11 6 21
 $ H: Factor w/ 4 levels "7","12","20",..: 1 3 4 2
 $ I: int  23 24 13 8
 $ J: int  10 25 4 33

If you're trying to insert in to last_accessed_on, which is a DateTime2, then your issue is with the fact that you are converting it to a varchar in a format that SQL doesn't understand.

If you modify your code to this, it should work, note the format of your date has been changed to: YYYY-MM-DD hh:mm:ss:

UPDATE  student_queues 
SET  Deleted=0, 
     last_accessed_by='raja', 
     last_accessed_on=CONVERT(datetime2,'2014-07-23 09:37:00')
WHERE std_id IN ('2144-384-11564') AND reject_details='REJECT'

Or if you want to use CAST, replace with:

CAST('2014-07-23 09:37:00.000' AS datetime2)

This is using the SQL ISO Date Format.

If you don't want to import some big library you could just use Intl.DateTimeFormat to convert Date objects to different timezones.

// Specifying timeZone is what causes the conversion, the rest is just formatting
const options = {
  year: '2-digit', month: '2-digit', day: '2-digit',
  hour: '2-digit', minute: '2-digit', second: '2-digit',
  timeZone: 'Asia/Jakarta',
  timeZoneName: 'short'
}
const formatter = new Intl.DateTimeFormat('sv-SE', options)
const startingDate = new Date("2012/04/10 10:10:30 +0000")

const dateInNewTimezone = formatter.format(startingDate) 
console.log(dateInNewTimezone) // 12-04-10 17:10:30 GMT+7

Offsets, daylight saving, and changes in the past will be taken care of for you.

The last argument of CONVERT seems to determine the format used for parsing. Consult MSDN docs for CONVERT.

111 - the one you are using is Japan yy/mm/dd.

I guess the one you are looking for is 103, that is dd/mm/yyyy.

So you should try:

 SELECT convert(datetime, '23/07/2009', 103)

I'm not sure what the minimum required version of Visual Studio is, but in VS2015 you can use

Public ReadOnly Property Name As String

It is read-only for public access but can be privately modified using _Name

Your best bet is to review the Java Swing tutorials, specifically the tutorial on Buttons.

The short code snippet is:

jBtnDrawCircle.addActionListener( /*class that implements ActionListener*/ );

I would place this as a comment to Triptych, but I can't comment yet due to lack of rating:

Using the enumerator method to match on sub-indices in a list of tuples. e.g.

li = [(1,2,3,4), (11,22,33,44), (111,222,333,444), ('a','b','c','d'),
        ('aa','bb','cc','dd'), ('aaa','bbb','ccc','ddd')]

# want pos of item having [22,44] in positions 1 and 3:

def getIndexOfTupleWithIndices(li, indices, vals):

    # if index is a tuple of subindices to match against:
    for pos,k in enumerate(li):
        match = True
        for i in indices:
            if k[i] != vals[i]:
                match = False
                break;
        if (match):
            return pos

    # Matches behavior of list.index
    raise ValueError("list.index(x): x not in list")

idx = [1,3]
vals = [22,44]
print getIndexOfTupleWithIndices(li,idx,vals)    # = 1
idx = [0,1]
vals = ['a','b']
print getIndexOfTupleWithIndices(li,idx,vals)    # = 3
idx = [2,1]
vals = ['cc','bb']
print getIndexOfTupleWithIndices(li,idx,vals)    # = 4

Its so simple just use this

header("location:javascript://history.go(-1)");

Its working fine for me

Nowadays, I'd prefer always having this helper, as suggested at an php.net/end answer.

<?php
function endc($array) {
    return end($array);
}

$items = array('one','two','three');
$lastItem = endc($items); // three
$current = current($items); // one
?>

This will always keeps the pointer as it is and we will never have to worry about parenthesis, strict standards or whatever.

You can try this

click Help>Install New Software on the menu bar

You can't use findViewById() on menu items in onCreate() because the menu layout isn't inflated yet. You could create a global Menu variable and initialize it in the onCreateOptionsMenu() and then use it in your onClick().

private Menu menu;

In your onCreateOptionsMenu()

this.menu = menu;

In your button's onClick() method

menu.getItem(0).setIcon(ContextCompat.getDrawable(this, R.drawable.ic_launcher));

split (from GNU coreutils, since version 8.8 from 2010-12-22) includes the following parameter:

-n, --number=CHUNKS     generate CHUNKS output files; see explanation below

CHUNKS may be:
  N       split into N files based on size of input
  K/N     output Kth of N to stdout
  l/N     split into N files without splitting lines/records
  l/K/N   output Kth of N to stdout without splitting lines/records
  r/N     like 'l' but use round robin distribution
  r/K/N   likewise but only output Kth of N to stdout

Thus, split -n 4 input output. will generate four files (output.a{a,b,c,d}) with the same amount of bytes, but lines might be broken in the middle.

If we want to preserve full lines (i.e. split by lines), then this should work:

split -n l/4 input output.

It seems that when this error appears it is an indication that the selenium-java plugin for maven is out-of-date.

Changing the version in the pom.xml should fix the problem

I tried several combinations from existing answers, but they were giving me

DefaultAppPool
IIS APPPOOL
IIS APPPOOL\DefaultAppPool

I ended up using

string vUserName = User.Identity.Name;

Which gave me the actual users domain username only.

Yes, this is a current issue in Chrome. There is an issue report here.

The fix will appear in 40.x.y.z versions.

Until then? I don't think you can resolve the issue yourself. But you can ignore it. The shown error is only related to the dev tools and does not influence the behavior of your website. If you have any other problems they are not related to this error.

You can use the syntax: $ENV{environment-variable} in your CMakeLists.txt to access environment variables. You could create scripts which initialize a set of environment variables appropriately and just have references to those variables in your CMakeLists.txt files.

try this:

public boolean verifyPwd(){
        if (!(pword.equals(pwdRetypePwd.getText()))){
                  txtaError.setEditable(true);
                  txtaError.setText("*Password didn't match!");

        }

}

if (verifyPwd()==true){
    addNewUser();

You can't call something on the entire viewModel, but on an individual observable you can call myObservable.valueHasMutated() to notify subscribers that they should re-evaluate. This is generally not necessary in KO, as you mentioned.

You may try the following (the program can be further optimized):

path = "/abc/test1.txt"
fh = open (path, 'r')
ip_arr_tmp = []
ip_arr = []
ip_arr_invalid = []

for lines in fh.readlines():
    resp = re.search ("([0-9]+).([0-9]+).([0-9]+).([0-9]+)", lines)
    print resp

    if resp != None:
       (p1,p2,p3,p4) = [resp.group(1), resp.group(2), resp.group(3), resp.group(4)]       

       if (int(p1) < 0 or int(p2) < 0 or int(p3) < 0 or int(p4) <0):
           ip_arr_invalid.append("%s.%s.%s.%s" %(p1,p2,p3,p4))

       elif (int(p1) > 255 or int(p2) > 255 or int(p3) > 255 or int(p4) > 255):
            ip_arr_invalid.append("%s.%s.%s.%s" %(p1,p2,p3,p4))

       elif (len(p1)>3 or len(p2)>3 or len(p3)>3 or len(p4)>3):
            ip_arr_invalid.append("%s.%s.%s.%s" %(p1,p2,p3,p4))

       else:

Thanks Philip this helped me - my use case was I had a form with lot of input fields so I maintained initial state as object and I was not able to update the object state.The above post helped me :)

const [projectGroupDetails, setProjectGroupDetails] = useState({
    "projectGroupId": "",
    "projectGroup": "DDD",
    "project-id": "",
    "appd-ui": "",
    "appd-node": ""    
});

const inputGroupChangeHandler = (event) => {
    setProjectGroupDetails((prevState) => ({
       ...prevState,
       [event.target.id]: event.target.value
    }));
}

<Input 
    id="projectGroupId" 
    labelText="Project Group Id" 
    value={projectGroupDetails.projectGroupId} 
    onChange={inputGroupChangeHandler} 
/>

The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

Two ways I've used it... first:

SET /P variable=

When batch file reaches this point (when left blank) it will halt and wait for user input. Input then becomes variable.

And second:

SET /P variable=<%temp%\filename.txt

Will set variable to contents (the first line) of the txt file. This method won't work unless the /P is included. Both tested on Windows 8.1 Pro, but it's the same on 7 and 10.

Just for the record, if you want to have a named sort-function, the syntax is as follows:

let sortFunction = (a, b) => {
 if(a.firstname < b.firstname) { return -1; }
 if(a.firstname > b.firstname) { return 1; }
 return 0;
})
users.sort(sortFunction)

Note that the following does NOT work:

users.sort(sortFunction(a,b))

Use sql from sql:

spool output of this to a file:

select 'alter index '||owner||'.'||index_name||' rebuild tablespace TO_TABLESPACE_NAME;' from all_indexes where owner='OWNERNAME';

spoolfile will have something like this:

alter index OWNER.PK_INDEX rebuild tablespace CORRECT_TS_NAME;

One classic root cause for this message is:

• when the repo has been initialized (git init lis4368/assignments),
• but no commit has ever been made

Ie, if you don't have added and committed at least once, there won't be a local master branch to push to.

Try first to create a commit:

• either by adding (git add .) then git commit -m "first commit"
  (assuming you have the right files in place to add to the index)
• or by create a first empty commit: git commit --allow-empty -m "Initial empty commit"

And then try git push -u origin master again.

See "Why do I need to explicitly push a new branch?" for more.

I don't know about other browsers, but IE7 has a 2083 character limit for HTTP GET operations. Unless any other browsers have lower limits, I don't see why you'd need any more characters than 2083.

DllImport will work fine without the complete path specified as long as the dll is located somewhere on the system path. You may be able to temporarily add the user's folder to the path.

You can do the following:

Load the data:

test <- read.csv(
          "http://archive.ics.uci.edu/ml/machine-learning-databases/breast-cancer-wisconsin/breast-cancer-wisconsin.data",
          header=FALSE)

Note that the default value of the header argument for read.csv is TRUE so in order to get all lines you need to set it to FALSE.

Add names to the different columns in the data.frame

names(test) <- c("A","B","C","D","E","F","G","H","I","J","K")

or alternative and faster as I understand (not reloading the entire dataset):

colnames(test) <- c("A","B","C","D","E","F","G","H","I","J","K")

Using ps -aux reveals current processes, all of which are listed in /proc/ as /proc/(pid)/, by calling cat /proc/(pid)/fd/0 it prints anything that is found in the standard output of that process I think. So perhaps,

/proc/(pid)/fd/0 - Standard Output File
/proc/(pid)/fd/1 - Standard Input File
/proc/(pid)/fd/2 - Standard Error File

for example

But only worked this well for /bin/bash other processes generally had nothing in 0 but many had errors written in 2

Leave your email.php code the same, but replace this JavaScript code:

 var name = $("#form_name").val();
        var email = $("#form_email").val();
        var text = $("#msg_text").val();
        var dataString = 'name='+ name + '&email=' + email + '&text=' + text;

        $.ajax({
            type: "POST",
            url: "email.php",
            data: dataString,
            success: function(){
            $('.success').fadeIn(1000);
            }
        });

with this:

    $.ajax({
        type: "POST",
        url: "email.php",
        data: $(form).serialize(),
        success: function(){
        $('.success').fadeIn(1000);
        }
    });

So that your form input names match up.

For the time being I am going a different route than I previous stated. I changed the way I am formatting the data to:

  &A2168=1&A1837=5&A8472=1&A1987=2

On the server side I am using getParameterNames() to place all the keys into an Enumerator and then iterating over the Enumerator and placing the keys and values into a HashMap. It looks something like this:

Enumeration keys = request.getParameterNames(); 
HashMap map = new HashMap(); 
String key = null; 
while(keys.hasMoreElements()){ 
      key = keys.nextElement().toString(); 
      map.put(key, request.getParameter(key)); 
}

I found adding constraint programmatically much easier than in storyboard.

    var leadingMargin = NSLayoutConstraint(item: self.tableView, attribute: NSLayoutAttribute.LeadingMargin, relatedBy: NSLayoutRelation.Equal, toItem: self.mView, attribute: NSLayoutAttribute.LeadingMargin, multiplier: 1, constant: 0.0)

    var trailingMargin = NSLayoutConstraint(item: self.tableView, attribute: NSLayoutAttribute.TrailingMargin, relatedBy: NSLayoutRelation.Equal, toItem: mView, attribute: NSLayoutAttribute.TrailingMargin, multiplier: 1, constant: 0.0)

    var height = NSLayoutConstraint(item: self.tableView, attribute: NSLayoutAttribute.Height, relatedBy: NSLayoutRelation.Equal, toItem: nil, attribute: NSLayoutAttribute.NotAnAttribute, multiplier: 1, constant: screenSize.height - 55)

    var bottom = NSLayoutConstraint(item: self.tableView, attribute: NSLayoutAttribute.BottomMargin, relatedBy: NSLayoutRelation.Equal, toItem: self.mView, attribute: NSLayoutAttribute.BottomMargin, multiplier: 1, constant: screenSize.height - 200)

    var top = NSLayoutConstraint(item: self.tableView, attribute: NSLayoutAttribute.TopMargin, relatedBy: NSLayoutRelation.Equal, toItem: self.mView, attribute: NSLayoutAttribute.TopMargin, multiplier: 1, constant: 250)

    self.view.addConstraint(leadingMargin)
    self.view.addConstraint(trailingMargin)
    self.view.addConstraint(height)
    self.view.addConstraint(bottom)
    self.view.addConstraint(top)

If you wanted a looser criterion for rejection, for example, to reject empty strings as well as nil, you could use:

[1, nil, 3, 0, ''].reject(&:blank?)
 => [1, 3, 0] 

If you wanted to go further and reject zero values (or apply more complex logic to the process), you could pass a block to reject:

[1, nil, 3, 0, ''].reject do |value| value.blank? || value==0 end
 => [1, 3]

[1, nil, 3, 0, '', 1000].reject do |value| value.blank? || value==0 || value>10 end
 => [1, 3]
