Try this one. You can strip just ' and " with:

$FileName = str_replace(array('\'', '"'), '', $UserInput); 

Try this library:

https://github.com/avast/android-styled-dialogs

It's based on DialogFragments instead of AlertDialogs (like the one from @afollestad). The main advantage: Dialogs don't dismiss after rotation and callbacks still work.

var name = from DataRow dr in tblClassCode.Rows where (long)dr["ID"] == Convert.ToInt32(i) select (int)dr["Name"]).FirstOrDefault().ToString() 

Uninstalling and re-installing the NuGet package worked for me.

1. Remove any old reference from the project.

Execute this in the Package Manager Console:

2. UnInstall-Package Microsoft.AspNet.WebApi.Core -version 5.2.3
3. Install-Package Microsoft.AspNet.WebApi.Core -version 5.2.3

You can get this easily via c#

private static string GetPublicKeyTokenFromAssembly(Assembly assembly)
{
    var bytes = assembly.GetName().GetPublicKeyToken();
    if (bytes == null || bytes.Length == 0)
        return "None";

    var publicKeyToken = string.Empty;
    for (int i = 0; i < bytes.GetLength(0); i++)
        publicKeyToken += string.Format("{0:x2}", bytes[i]);

    return publicKeyToken;
}

EDIT : this answer used to claim that it isn't possible to center an absolutely positioned element with margin: auto;, but this simply isn't true. Because this is the most up-voted and accepted answer, I guessed I'd just change it to be correct.

When you apply the following CSS to an element

position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
margin: auto;

And then give the element a fixed width and height, such as 200px or 40%, the element will center itself.

Here's a Fiddle that demonstrates the effect.

You could use one of the below solutions:

$items = Item::whereIn('id', [1,2,..])->get();

or:

$items = DB::table('items')->whereIn('id',[1,2,..])->get();

if the content of foo.py

print __name__
if __name__ == '__main__':
    print 'XXXX'

A file foo.py can be used in two ways.

• imported in another file : import foo

In this case __name__ is foo, the code section does not get executed and does not print XXXX.

• executed directly : python foo.py

When it is executed directly, __name__ is same as __main__ and the code in that section is executed and prints XXXX

One of the use of this functionality to write various kind of unit tests within the same module.

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

It turns out that there is a float: left property by default on all navbar-nav>li elements, which is why they were all scrunching up to the left. Once I added the code below, it made the navbar both centered and not scrunched up.

.navbar-nav>li {
        float: none;
}

Hope this helps someone else who's looking to center a navbar.

Delete *.err files that you find in the directory displayed in the error and create the file mysql is complaining about, restart mysql.

mkdir [-switch] foldername

-p is a switch which is optional, it will create subfolder and parent folder as well even parent folder doesn't exist.

From the man page:

-p, --parents no error if existing, make parent directories as needed

Example:

mkdir -p storage/framework/{sessions,views,cache}

This will create subfolder sessions,views,cache inside framework folder irrespective of 'framework' was available earlier or not.

This issue is because of you having some local or private packages. For accessing those packages you have to create .npmrc file for this issue. Just refer the following link for your solution. https://nodesource.com/blog/configuring-your-npmrc-for-an-optimal-node-js-environment

You can't modify a collection while you're iterating over it with foreach. You might try using a regular for() statement.

You may need to iterate backwards from the end of the collection to make sure you cover every item in the collection and don't accidentally overrun the end of the collection after removing an item (since the length would change). I can't remember if .NET accounts for that possibility or not.

Do this in your .profile -

export JAVA_HOME=`/usr/libexec/java_home`

(backticks make sure to execute the command and place its value in JAVA_HOME)

A late answer but this is how I make my ActionLink into a button. We're using Bootstrap in our project as it makes it convenient. Never mind the @T since its only an translator we're using.

@Html.Actionlink("Some_button_text", "ActionMethod", "Controller", "Optional parameter", "html_code_you_want_to_apply_to_the_actionlink");

The above gives a link like this and it looks as the picture below:

localhost:XXXXX/Firms/AddAffiliation/F0500

In my view:

@using (Html.BeginForm())
{
<div class="section-header">
    <div class="title">
        @T("Admin.Users.Users")
    </div>
    <div class="addAffiliation">
        <p />
        @Html.ActionLink("" + @T("Admin.Users.AddAffiliation"), "AddAffiliation", "Firms", new { id = (string)@WorkContext.CurrentFirm.ExternalId }, new { @class="btn btn-primary" })
    </div>
</div>

}

strtotime will work that out. the dates are just not the same and all in us-format.

<?php
$e1 = strtotime("2013-07-22T12:00:03Z");
echo date('y.m.d H:i', $e1);
echo "2013-07-22T12:00:03Z";

$e2 = strtotime("2013-07-23T18:18:15Z");
echo date ('y.m.d H:i', $e2);
echo "2013-07-23T18:18:15Z";

$e1 = strtotime("2013-07-21T23:57:04Z");
echo date ('y.m.d H:i', $e2);
echo "2013-07-21T23:57:04Z";
?>

Surely an easy fix to get rid of the '1 hours ago' problem would be to increase the window that 'an hour ago' is valid for. Change

if (delta < 5400) // 90 * 60
{
    return "an hour ago";
}

into

if (delta < 7200) // 120 * 60
{
    return "an hour ago";
}

This means that something that occurred 110 minutes ago will read as 'an hour ago' - this may not be perfect, but I'd say it is better than the current situation of '1 hours ago'.

Git 1.8.2 features a new option, --remote, that will enable exactly this behavior. Running

git submodule update --remote --merge

will fetch the latest changes from upstream in each submodule, merge them in, and check out the latest revision of the submodule. As the documentation puts it:

--remote

This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.

This is equivalent to running git pull in each submodule, which is generally exactly what you want.

you have to check your pip package to be updated to the latest version in your pycharm and then install numpy package. in settings -> project:progLangComp -> Project Interpreter there is a table of packages and their current version (just labelled as Version) and their latest version (labelled as Latest). Pip current version number should be the same as latest version. If you see a blue arrow in front of pip, you have to update it to the latest then trying to install numpy or any other packages that you couldn't install, for me it was pandas which I wanted to install.

also it happens when you import following library to api.php file. this happens by some IDE's suggestion to import it for not finding the Route Class.

just remove it and everything going to work fine.

use Illuminate\Routing\Route;

update:

seems if you add this library it wont lead to error

use Illuminate\Support\Facades\Route;

Here is a really good way to manage this error. You can put the below line in .eslintrc.js file.

Based on the operating system, it will take appropriate line endings.

rules: {
        'linebreak-style': ['error', process.platform === 'win32' ? 'windows' : 'unix'],
 }

For a Dotted effect on a Canvas, set this attribute to the paint object :

paint.setPathEffect(new DashPathEffect(new float[] {0,30}, 0));

And change the value 30 as your render suits you : it represents the "distance" between each dots.

Something like:

var divided = str.split("/~/");
var name=divided[0];
var street = divided[1];

Is probably going to be easiest

They are normal symbols as 'a' or '?' or any other. Just (invisible) entries in a string. \r moves cursor to the beginning of the line. \n goes one line down.

As for your replacement, you haven't specified what language you're using, so here's the sketch:

someString.replace("\r\n", "\n").replace("\r", "\n")

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

This is working for me and really very helpful.

SubCategory.update({ _id: { $in:
        arrOfSubCategory.map(function (obj) {

    } },
    {
        $pull: {
            coupon: couponId,
        }
    }, { multi: true }, function (err, numberAffected) {
        if(err) {
            return callback({
                error:err
            })
        }
    })
});

I have a model which name is SubCategory and I want to remove Coupon from this category Array. I have an array of categories so I have used arrOfSubCategory. So I fetch each array of object from this array with map function with the help of $in operator.

you can use webview to show the pdf inside an application , for that you have to :

1. convert the pdf to html file and store it in asset folder
2. load the html file to the web view ,

Many pdf to html online converter available.

Example:

    consent_web = (WebView) findViewById(R.id.consentweb);
    consent_web.getSettings().setLoadWithOverviewMode(true);
    consent_web.getSettings().setUseWideViewPort(true);
    consent_web.loadUrl("file:///android_asset/spacs_html.html");

You can disable them altogether by

(setq make-backup-files nil)

To convert integer to char only 0 to 9 will be converted. As we know 0's ASCII value is 48 so we have to add its value to the integer value to convert in into the desired character hence

int i=5;
char c = i+'0';

If you want to quit without saving in Vim and have Vim return a non-zero exit code, you can use :cq.

I use this all the time because I can't be bothered to pinky shift for !. I often pipe things to Vim which don't need to be saved in a file. We also have an odd SVN wrapper at work which must be exited with a non-zero value in order to abort a checkin.

In idlelib.PyShell module, root variable of type Tk is defined to be global

At the end of PyShell.main() function it calls root.mainloop() function which is an infinite loop and it runs till the loop is interrupted by root.quit() function. Hence, root.quit() will only interrupt the execution of mainloop

In order to destroy all widgets pertaining to that idlelib window, root.destroy() needs to be called, which is the last line of idlelib.PyShell.main() function.

For me following was working:

var completionHandler:((Float)->Void)!

There isn't any in printf - the two are synonyms.

One more solution which is easy to understand :)

var newstring = mystring.split('.').join(' ');

Following code will manage to refresh parent window post close :

function ManageQB_PopUp() {
            $(document).ready(function () {
                window.close();
            });
            window.onunload = function () {
                var win = window.opener;
                if (!win.closed) {
                    window.opener.location.reload();
                }
            };
        }

if (string.IsNullOrWhiteSpace(fileName)) return Content("filename not present");

        var path = Path.Combine(your path, your filename);

        var stream = new FileStream(path, FileMode.Open);

        return File(stream, System.Net.Mime.MediaTypeNames.Application.Octet, fileName);

To get a console log from a background page you need to write the following code snippet in your background page background.js -

 chrome.extension.getBackgroundPage().console.log('hello');

Then load the extension and inspect its background page to see the console log.

I know this is an old question, but we were faced with the same problem when trying to inject Strings. So we invented a JUnit5/Mockito extension that does exactly what you want: https://github.com/exabrial/mockito-object-injection

EDIT:

@InjectionMap
 private Map<String, Object> injectionMap = new HashMap<>();

 @BeforeEach
 public void beforeEach() throws Exception {
  injectionMap.put("securityEnabled", Boolean.TRUE);
 }

 @AfterEach
 public void afterEach() throws Exception {
  injectionMap.clear();
 }

In Java, all strings are immutable. When you are trying to modify a String, what you are really doing is creating a new one. However, when you use a StringBuilder, you are actually modifying the contents, instead of creating a new one.

The args of print_the_arguments is arguments, so you should use:

struct arg_struct *args = (struct arg_struct *)arguments. 

To generate a certificate on the Apple provisioning profile website, firstly you have to generate keys on your mac, then upload the public key. Apple will generate your certificates with this key. When you download your certificates, tu be able to use them you need to have the private key.

The error "XCode could not find a valid private-key/certificate pair for this profile in your keychain." means you don't have the private key.

Maybe because your Mac was reinstalled, maybe because this key was generated on another Mac. So to be able to use your certificates, you need to find this key and install it on the keychain.

If you can not find it you can generate new keys restart this process on the provisioning profile website and get new certificates you will able to use.

You can use if expression for this in Kotlin. In Kotlin if is an expression with a result value. So in Kotlin we can write

fun max(a: Int, b: Int) = if (a > b) a else b

and in Java we can achieve the same but with larger code

int max(int a, int b) {
return a > b ? a : b
}

      var circle = new google.maps.Circle({
        center: geolocation,
        radius: position.coords.accuracy
      });
      autocomplete.setBounds(circle.getBounds());
    });
  }
}

Use enumerate:

testlist = [1,2,3,5,3,1,2,1,6]
for position, item in enumerate(testlist):
    if item == 1:
        print position

a bit change in format

format : "DD/MM/YYYY"

<div data-ng-init="featureClass=false" 
     data-ng-click="featureClass=!featureClass" 
     data-ng-class="{'active': featureClass}">
    Click me to toggle my class!
</div>

Analogous to jQuery's toggleClass method, this is a way to toggle the active class on/off when the element is clicked.

Just to go a little bit further in the matter, you can also set a bitmap directly, like this:

ImageView imageView = new ImageView(this);  
Bitmap bImage = BitmapFactory.decodeResource(this.getResources(), R.drawable.my_image);
imageView.setImageBitmap(bImage);

Of course, this technique is only useful if you need to change the image.

It is highly NOT ADVISABLE to copy projects at all because the some config files formed internally like .csproj, .vspscc etc. may (and most probably will) point to references which belong to previous solutions' location and other paths/locations in system or TFS. Unless you are an expert at reading these files and fixing references, do not try to copy projects.

You can create a skeletal project of the same type you intend to copy, this creates a proper .csproj, .vspscc files. Now you are free to copy the class files,scripts and other content from the previous project as they will not impact. This will ensure a smooth build and version control (should you choose to be interested in that)

Having said all this, let me give you the method to copy project anyhow in a step-wise manner:

1. Go to the project you want to copy in solution explorer and right-click.
2. Now select 'Open Folder in File Explorer' (Assuming you have the solution mapped to a local path on your disk).
3. Select the Projects you want to replicate as whole folders(along with all dependencies,bin .vspscc file, .csproj file)
4. Paste them in your desired location (it could be your same solution folder or even another solution folder. If it is within the same solution folder, then you would be required to rename it, also the .csproj and other internal files to the new name).
5. No go back to Visual Studio, Right-Click on Solution > Add > Existing Project...
6. Browse and select the Project file (.csproj file) now from the location you placed it in and select 'open'
7. This file now appears in the solution explorer for you to work.

You may now have to resolve a few build errors probably with duplicated/missing references and stuff but otherwise it's as pristine in logic and structure as you expected it to be.

It appears that SQL Server 2008 R2 can be downloaded with or without the management tools. I honestly have NO IDEA why someone would not want the management tools. But either way, the options are here:

http://www.microsoft.com/sqlserver/en/us/editions/express.aspx

and the one for 64 bit WITH the management tools (management studio) is here:

http://www.microsoft.com/sqlserver/en/us/editions/express.aspx

From the first link I presented, the 3rd and 4th include the management studio for 32 and 64 bit respectively.

You can set your hash directly to URL too.

window.location.hash = "YourHash";

The result : http://url#YourHash

Bassed on the excellent answer of T.J. Crowder: (Off-topic: Avoid cluttering window)

This is an example of his idea:

Html

<!DOCTYPE html>
<html>
  <head>
    <script type="text/javascript" src="init.js"></script>
    <script type="text/javascript">
      MYLIBRARY.init(["firstValue", 2, "thirdValue"]);
    </script>
    <script src="script.js"></script>
  </head>

  <body>
    <h1>Hello !</h1>
  </body>    
</html>

init.js (Based on this answer)

var MYLIBRARY = MYLIBRARY || (function(){
    var _args = {}; // private

    return {
        init : function(Args) {
            _args = Args;
            // some other initialising
        },
        helloWorld : function(i) {
            return _args[i];
        }
    };
}());

script.js

// Here you can use the values defined in the html as if it were a global variable
var a = "Hello World " + MYLIBRARY.helloWorld(2);

alert(a);

Here's the plnkr. Hope it help !

I had the same error, though the problem was that I had a typo in the url

url: 'http://api.example.com/TYPO'

The API had a redirect to another domain for all URL's that is wrong (404 errors).

So fixing the typo to the correct URL fixed it for me.

I couldn't find a simple example about the differences between ES6 and ES5, so I made one. Both code samples create exactly the same object. But the ES5 example also works in older browsers (like IE11), wheres the ES6 example doesn't.

ES6

var matrix = {};
var a = 'one';
var b = 'two';
var c = 'three';
var d = 'four';

matrix[a] = {[b]: {[c]: d}};

ES5

var matrix = {};
var a = 'one';
var b = 'two';
var c = 'three';
var d = 'four';

function addObj(obj, key, value) {
  obj[key] = value;
  return obj;
}

matrix[a] = addObj({}, b, addObj({}, c, d));

In addition to Guffa's answer, you could use this variant to have a more shorthanded notation.

public static bool ScrambledEquals<T>(this IEnumerable<T> list1, IEnumerable<T> list2)
{
  var deletedItems = list1.Except(list2).Any();
  var newItems = list2.Except(list1).Any();
  return !newItems && !deletedItems;          
}

select A, B, 'c' as C
from MyTable

You can get its shape with:

print((df.count(), len(df.columns)))

IEnumerable is an interface, instead of looking for how to create an interface instance, create an implementation that matches the interface: create a list or an array.

IEnumerable<string> myStrings = new [] { "first item", "second item" };
IEnumerable<string> myStrings = new List<string> { "first item", "second item" };

Use input.nextLine(); instead of input.next();

there are two ways to do this in jquery depending what you are looking for..

using jquery you can do

• //this will wait for the text assets to be loaded before calling this (the dom.. css.. js)

  $(document).ready(function(){...});
  

• //this will wait for all the images and text assets to finish loading before executing

  $(window).load(function(){...});
  

I had approximately the same problem with Laravel 5.5 on ubuntu, finally i've found a solution here to switch between the versions of php used by apache :

1. sudo a2dismod php5
2. sudo a2enmod php7.1
3. sudo service apache2 restart

and it works

You can parse urls using modern JS:

var my_url = new URL('http://www.google.sk/foo?boo=123#baz');

my_url.hash; // outputs "#baz"
my_url.pathname; // outputs "/moo"
?my_url.protocol; // "http:"
?my_url.search; // outputs "?doo=123"

urls with no hash will return empty string.

Instead of including your js file extension in index.html, you can include it in .angular-cli-json file.

These are the steps I followed to get this working:

1. First include your external js file in assets/js
2. In .angular-cli.json - add the file path under scripts: [../app/assets/js/test.js]
3. In the component where you want to use the functions of the js file.

Declare at the top where you want to import the files as

declare const Test:any;

After this you can access its functions as for example Test.add()

For those who can't install wkhtmltopdf in their systems, one more method other than many already mentioned in the answers to this question is to simply download the file as an html file from the jupyter notebook, upload that to HTML to PDF, and download the converted pdf files from there.

Here you have your IPython notebook(.ipynb) converted to both PDF(.pdf) & HTML(.html) formats.

If the place you're gonna paste have no problem with pasting a table formating (like the browser URL bar), I think the easiest way is this:

Sheets(1).Range("A1000").Value = string
Sheets(1).Range("A1000").Copy
MsgBox "Paste before closing this dialog."
Sheets(1).Range("A1000").Value = ""

You need to put your directory structure in your project directory. And then click "Show All Files" icon in the top of Solution Explorer toolbox. After that, the added directory will be shown up. You will then need to select this directory, right click, and choose "Include in Project."

?? No, Nesting an html button in an html a (or vice-versa) is not valid html

You can use this jsFiddle

And HTML:

<div id="previewBox">
    <button id="closeButton">Close</button>
<a class="fragment" href="google.com">
    <div>
    <img src ="http://placehold.it/116x116" alt="some description"/> 
    <h3>the title will go here</h3>
        <h4> www.myurlwill.com </h4>
    <p class="text">
        this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etcthis is a short description yada yada peanuts etc 
    </p>
</div>
</a>
</div>

With JS (jquery required):

$(document).ready(function() {
    $('#closeButton').on('click', function(e) { 
        $('#previewBox').remove(); 
    });
});

Looking for EventHandling, ActionListener?

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        textfield.setText("");
        //textfield.setText(null); //or use this
    }
});

Another thought occurred to me just now that could be a pure CSS solution. Display your active class as an absolutely positioned block and set its style to cover up the parent li.

a.active {
   position:absolute;
   display:block;
   width:100%;
   height:100%;
   top:0em;
   left:0em;
   background-color: whatever;
   border: whatever;
}
/* will also need to make sure the parent li is a positioned element so... */
ul.menu li {
    position:relative;
}    

For those of you who want to use javascript without jquery...

Selecting the parent is trivial. You need a getElementsByClass function of some sort, unless you can get your drupal plugin to assign the active item an ID instead of Class. The function I provided I grabbed from some other genius on SO. It works well, just keep in mind when you're debugging that the function will always return an array of nodes, not just a single node.

active_li = getElementsByClass("active","a");
active_li[0].parentNode.style.whatever="whatever";

function getElementsByClass(node,searchClass,tag) {
    var classElements = new Array();
    var els = node.getElementsByTagName(tag); // use "*" for all elements
    var elsLen = els.length;
    var pattern = new RegExp("\\b"+searchClass+"\\b");
    for (i = 0, j = 0; i < elsLen; i++) {
       if ( pattern.test(els[i].className) ) {
       classElements[j] = els[i];
       j++;
   }
}
return classElements;
}

I recently wrote a universal function to manage this for you if you want to use it.

/**
 * Sorts an object into an order
 *
 * @require jQuery
 *
 * @param object Our JSON object to sort
 * @param type Only alphabetical at the moment
 * @param identifier The array or object key to sort by
 * @param order Ascending or Descending
 *
 * @returns Array
 */
function sortItems(object, type, identifier, order){

    var returnedArray = [];
    var emptiesArray = []; // An array for all of our empty cans

    // Convert the given object to an array
    $.each(object, function(key, object){

        // Store all of our empty cans in their own array
        // Store all other objects in our returned array
        object[identifier] == null ? emptiesArray.push(object) : returnedArray.push(object);

    });

    // Sort the array based on the type given
    switch(type){

        case 'alphabetical':

            returnedArray.sort(function(a, b){

                return(a[identifier] == b[identifier]) ? 0 : (

                    // Sort ascending or descending based on order given
                    order == 'asc' ? a[identifier] > b[identifier] : a[identifier] < b[identifier]

                ) ? 1 : -1;

            });

            break;

        default:

    }

    // Return our sorted array along with the empties at the bottom depending on sort order
    return order == 'asc' ? returnedArray.concat(emptiesArray) : emptiesArray.concat(returnedArray);

}

Similar to Stan answer but :

• if you have more than one button, you have to get only the first button => [0]
• if the form can be submitted with the enter key, you have to manage a default => myDefaultButtonId

$(document).on('submit', function(event) {
    event.preventDefault();
    var pressedButtonId = 
         typeof $(":input[type=submit]:focus")[0] === "undefined" ? 
         "myDefaultButtonId" :
         $(":input[type=submit]:focus")[0].id;
    ...
 }

*nix provides a nice little command which makes our lives a lot easier.

GET:

with JSON:

curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X GET http://hostname/resource

with XML:

curl -H "Accept: application/xml" -H "Content-Type: application/xml" -X GET http://hostname/resource

POST:

For posting data:

curl --data "param1=value1&param2=value2" http://hostname/resource

For file upload:

curl --form "[email protected]" http://hostname/resource

man curl

For details about options/switches of the curl command, hit:

curl -h

You might sort the helper[] array directly:

java.util.Arrays.sort(helper, 1, helper.length);

Sorts the array from index 1 to the end. Leaves the first item at index 0 untouched.

See Arrays.sort(Object[] a, int fromIndex, int toIndex)

This is possible by using "**" pattern as following.

<exclude name="maindir/**/incomplete.flag"/>

the above 'exclude' will exclude all directories completely which contains incomplete.flag file.

You can try something like:

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

Just to add something I was missing from all the answers - even if it seems to be silly and obvious as soon as you know:

The file has to be named "App.config" or "app.config" and can be located in your project at the same level as e.g. Program.cs.

I do not know if other locations are possible, other names (like application.conf, as suggested in the ODP.net documentation) did not work for me.

PS. I started with Visual Studio Code and created a new project with "dotnet new". No configuration file is created in this case, I am sure there are other cases. PPS. You may need to add a nuget package to be able to read the config file, in case of .NET CORE it would be "dotnet add package System.Configuration.ConfigurationManager --version 4.5.0"

You can also use this:

private boolean doesUserHavePermission()
{
    int result = context.checkCallingOrSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE);
    return result == PackageManager.PERMISSION_GRANTED;
}

In swift 3 it is simple as given below

let stringDouble =  String(describing: double)

You can use UIAppearance once, at your application startup (before UI is loaded), to set it as default global settings:

// iOS 7:
[[UITableView appearance] setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];
[[UITableView appearance] setSeparatorInset:UIEdgeInsetsZero];

[[UITableViewCell appearance] setSeparatorInset:UIEdgeInsetsZero];

// iOS 8:
if ([UITableView instancesRespondToSelector:@selector(setLayoutMargins:)]) {

    [[UITableView appearance] setLayoutMargins:UIEdgeInsetsZero];
    [[UITableViewCell appearance] setLayoutMargins:UIEdgeInsetsZero];
    [[UITableViewCell appearance] setPreservesSuperviewLayoutMargins:NO];

}

This way, you keep your UIViewController's code clean and can always override it if you want.

Although my MySQL background is limited, I don't think you have much luck doing that. However, you should be able to migrate over all of your data by restoring the db to a MSSQL server, then creating a SSIS or DTS package to send your tables and data to the MySQL server.

hope this helps

make sure your user has attributes on its role. for example:

postgres=# \du
                             List of roles
 Role name |                   Attributes                   | Member of 
-----------+------------------------------------------------+-----------
 flux      |                                                | {}
 postgres  | Superuser, Create role, Create DB, Replication | {}

after performing the following command:

postgres=# ALTER ROLE flux WITH Superuser;
ALTER ROLE
postgres=# \du
                             List of roles
 Role name |                   Attributes                   | Member of 
-----------+------------------------------------------------+-----------
 flux      | Superuser                                      | {}
postgres  | Superuser, Create role, Create DB, Replication | {}

it fixed the problem.

see tutorial for roles and stuff here: https://www.digitalocean.com/community/tutorials/how-to-use-roles-and-manage-grant-permissions-in-postgresql-on-a-vps--2

Wildcard Characters are used with like clause to sort records.

if we want to search a string which is starts with B then code is like the following:

select * from tablename where colname like 'B%' order by columnname ;

if we want to search a string which is ends with B then code is like the following: select * from tablename where colname like '%B' order by columnname ;

if we want to search a string which is contains B then code is like the following: select * from tablename where colname like '%B%' order by columnname ;

if we want to search a string in which second character is B then code is like the following: select * from tablename where colname like '_B%' order by columnname ;

if we want to search a string in which third character is B then code is like the following: select * from tablename where colname like '__B%' order by columnname ;

note : one underscore for one character.

In the end I made a jQuery plugin that will format the <input type="number" /> appropriately for me. I also noticed on some mobile devices the min and max attributes don't actually prevent you from entering lower or higher numbers than specified, so the plugin will account for that too. Below is the code and an example:

(function($) {_x000D_
  $.fn.currencyInput = function() {_x000D_
    this.each(function() {_x000D_
      var wrapper = $("<div class='currency-input' />");_x000D_
      $(this).wrap(wrapper);_x000D_
      $(this).before("<span class='currency-symbol'>$</span>");_x000D_
      $(this).change(function() {_x000D_
        var min = parseFloat($(this).attr("min"));_x000D_
        var max = parseFloat($(this).attr("max"));_x000D_
        var value = this.valueAsNumber;_x000D_
        if(value < min)_x000D_
          value = min;_x000D_
        else if(value > max)_x000D_
          value = max;_x000D_
        $(this).val(value.toFixed(2)); _x000D_

Casting should be enough. If you're using C# 3.0 you can make a handy extension method to parse enum values:

public static TEnum ToEnum<TInput, TEnum>(this TInput value)
{
    Type type = typeof(TEnum);

    if (value == default(TInput))
    {
        throw new ArgumentException("Value is null or empty.", "value");
    }

    if (!type.IsEnum)
    {
        throw new ArgumentException("Enum expected.", "TEnum");
    }

    return (TEnum)Enum.Parse(type, value.ToString(), true);
}

Try using list.AddRange(VTSWeb.GetDailyWorktimeViolations(VehicleID2));

I want to add somethings different from definitions of words. Most of them will be visual.

Technically, LDAP is just a protocol that defines the method by which directory data is accessed.Necessarily, it also defines and describes how data is represented in the directory service

Data is represented in an LDAP system as a hierarchy of objects, each of which is called an entry. The resulting tree structure is called a Directory Information Tree (DIT). The top of the tree is commonly called the root (a.k.a base or the suffix).

To navigate the DIT we can define a path (a DN) to the place where our data is (cn=DEV-India,ou=Distrubition Groups,dc=gp,dc=gl,dc=google,dc=com will take us to a unique entry) or we can define a path (a DN) to where we think our data is (say, ou=Distrubition Groups,dc=gp,dc=gl,dc=google,dc=com) then search for the attribute=value or multiple attribute=value pairs to find our target entry (or entries).

If you want to get more depth information, you visit here

any large single block of data stored in a database, such as a picture or sound file, which does not include record fields, and cannot be directly searched by the database's search engine.

If you do not like double quotes like me, this will work for you with single quotes:

$value = Input::get('q');
$books = Book::where('name', 'LIKE', '%' . $value . '%')->limit(25)->get();

return view('pages/search/index', compact('books'));

For future visitors: In the new HttpClient (Angular 4.3+), the response object is JSON by default, so you don't need to do response.json().data anymore. Just use response directly.

Example (modified from the official documentation):

import { HttpClient } from '@angular/common/http';

@Component(...)
export class YourComponent implements OnInit {

  // Inject HttpClient into your component or service.
  constructor(private http: HttpClient) {}

  ngOnInit(): void {
    this.http.get('https://api.github.com/users')
        .subscribe(response => console.log(response));
  }
}

Don't forget to import it and include the module under imports in your project's app.module.ts:

...
import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    BrowserModule,
    // Include it under 'imports' in your application module after BrowserModule.
    HttpClientModule,
    ...
  ],
  ...

To follow up on the comment by suhendri to Rory McCrossan answer. Here is an Action delegate example:

In child add:

public Action UpdateProgress;  // In place of event handler declaration
                               // declare an Action delegate
.
.
.
private LoadData() {
    this.UpdateProgress();    // call to Action delegate - MyMethod in
                              // parent
}

In parent add:

// The 3 lines in the parent becomes:
ChildClass child = new ChildClass();
child.UpdateProgress = this.MyMethod;  // assigns MyMethod to child delegate

.process-list:after{
    content: "\2191";
    position: absolute;
    top:50%;
    right:-8px;
    background-color: #ea1f41;
    width:35px;
    height: 35px;
    border:2px solid #ffffff;
    border-radius: 5px;
    color: #ffffff;
    z-index: 10000;
    -webkit-transform: rotate(50deg) translateY(-50%);
    -moz-transform: rotate(50deg) translateY(-50%);
    -ms-transform: rotate(50deg) translateY(-50%);
    -o-transform: rotate(50deg) translateY(-50%);
    transform: rotate(50deg) translateY(-50%);
}

you can check this code . i hope you will easily understand.

Trying to build HelloWorld app on Ubuntu 16.04. Got error with drawable/icon. Solution could be:

cp ./platforms/android/build/intermediates/exploded-aar/com.android.support/design/25.3.1/res/drawable/navigation_empty_icon.xml    ./platforms/android/build/intermediates/exploded-aar/com.android.support/design/25.3.1/res/drawable/icon.xml

So, it look like icon.xml file missed.

If anyone gets this issue while using the integrated terminal in Visual Studio Code then there is a good chance it's updating. Restart Visual Studio Code and you will likely see the "New Version" tab and it should all start working again.

If you're reusing these bg images anywhere else on your site for form inputs, you probably want to use an image sprite. That way you can centrally manage your images (instead of having pic1, pic2, pic3, etc...).

Sprites are generally faster for the client, since they are only requesting one (albeit slightly larger) file from the server instead of multiple files. See SO article for more benefits:

CSS image sprites

Then again, this might not be helpful at all if you're just using these for one form and you really only want to load them if the user requests the contact form...might make sense though.

Django provides it. You can use either:

• {{ forloop.counter }} index starts at 1.
• {{ forloop.counter0 }} index starts at 0.

In template, you can do:

{% for item in item_list %}
    {{ forloop.counter }} # starting index 1
    {{ forloop.counter0 }} # starting index 0

    # do your stuff
{% endfor %}

More info at: for | Built-in template tags and filters | Django documentation

I did this way:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="actionMenuTextAppearance">@style/MenuTextAppearance</item>
    <item name="android:actionMenuTextAppearance">@style/MenuTextAppearance</item>
    <item name="actionMenuTextColor">@color/colorAccent</item>
</style>

<style name="MenuTextAppearance" >

1.You can make overload functions.

SomeF(strin s){}   
SomeF(string s, string s2){}    
SomeF(string s1, string s2, string s3){}   

More info: http://csharpindepth.com/Articles/General/Overloading.aspx

2.or you may create one function with params

SomeF( params string[] paramArray){}
SomeF("aa","bb", "cc", "dd", "ff"); // pass as many as you like

More info: https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/params

3.or you can use simple array

Main(string[] args){}

No need to care of whether before/after this digit having other type of words

To just match the pattern of 5 digits number anywhere in the string, no matter it is separated by space or not, use this regular expression (?<!\d)\d{5}(?!\d).

Sample JavaScript codes:

var regexp = new RegExp(/(?<!\d)\d{5}(?!\d)/g); 
    var matches = yourstring.match(regexp);
    if (matches && matches.length > 0) {
        for (var i = 0, len = matches.length; i < len; i++) {
            // ... ydo something with matches[i] ...
        } 
    }

Here's some quick results.

• abc12345xyz (?)

• 12345abcd (?)

• abcd12345 (?)

• 0000aaaa2 (?)

• a1234a5 (?)

• 12345 (?)

• <space>12345<space>12345 (??)

The only way to retrieve the correct value in your context is to run $.ajax() function synchronously (what actually contradicts to main AJAX idea). There is the special configuration attribute async you should set to false. In that case the main scope which actually contains $.ajax() function call is paused until the synchronous function is done, so, the return is called only after $.ajax().

function doSomething() {
    var status = 0;
    $.ajax({
        url: 'action.php',
        type: 'POST',
        data: dataString,
        async: false,
        success: function (txtBack) {
            if (txtBack == 1)
                status = 1;
        }
    });

    return status;
}

var response = doSomething();

As mentioned here that

df1[~df1.apply(tuple,1).isin(df2.apply(tuple,1))]

is correct solution but it will produce wrong output if

df1=pd.DataFrame({'A':[1],'B':[2]})
df2=pd.DataFrame({'A':[1,2,3,3],'B':[2,3,4,4]})

In that case above solution will give Empty DataFrame, instead you should use concat method after removing duplicates from each datframe.

Use concate with drop_duplicates

df1=df1.drop_duplicates(keep="first") 
df2=df2.drop_duplicates(keep="first") 
pd.concat([df1,df2]).drop_duplicates(keep=False)

A filter argument with a trailing * can be evaluated almost instantaneously via an index lookup. A leading * implies a sequential search through the index, so it is O(N). It will take ages.

I suggest you reconsider the requirement.

For me the issue was requesting a group mistakenly instead of the actual permissions.

Try:

final InputStream is = new URL("http://wwww.somewebsite.com/a.txt").openStream();

You could have simply replaced

names[i] = in.nextLine(); with names[i] = in.next();

Using next() will only return what comes before a space. nextLine() automatically moves the scanner down after returning the current line.

Like others mentioned, your app runs in a sandboxed environment and you can use the documents directory to store images or other assets your app may use, eg. downloading offline-d files as user prefers - File System Basics - Apple Documentation - Which directory to use, for storing application specific files

Updated to swift 5, you can use one of these functions, as per requirement -

func getDocumentsDirectory() -> URL {
    let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
    return paths[0]
}

func getCacheDirectory() -> URL {
        let paths = FileManager.default.urls(for: .cachesDirectory, in: .userDomainMask)
        return paths[0]
    }

func getApplicationSupportDirectory() -> URL {
        let paths = FileManager.default.urls(for: .applicationSupportDirectory, in: .userDomainMask)
        return paths[0]
    }

Usage:

let urlPath = "https://jumpcloud.com/wp-content/uploads/2017/06/SSH-Keys.png" //Or string path to some URL of valid image, for eg.

if let url = URL(string: urlPath){
    let destination = getDocumentsDirectory().appendingPathComponent(url.lastPathComponent)
    do {
        let data = try Data(contentsOf: url) //Synchronous call, just as an example
        try data.write(to: destination)
    } catch _ {
        //Do something to handle the error
    }
}

I encountered this bug when attempting to define a new OptionSetType struct in Swift 2. When I corrected the type on the init() parameter from Self.RawValue to Int the crash stopped occurring:

// bad:
//  public init(rawValue: Self.RawValue) {
//      self.rawValue = rawValue
//  }

// good:
public init(rawValue: Int) {
    self.rawValue = rawValue
}

Adding this answer because the previous answers permanently delete your changes

The Safe way

git stash -u

Explanation: Stash local changes including untracked changes (-u flag). The command saves your local modifications away and reverts the working directory to match the HEAD commit.

Want to recover the changes later?

git stash pop

Explanation: The command will reapply the changes to the top of the current working tree state.

Want to permanently remove the changes?

git stash drop

Explanation: The command will permanently remove the stashed entry

Link to git stash documentation

In answer ,it creates circular dependency.This can be avoided by removing parent inside Child nodes. i.e,

public class MyTreeNode<T>{     


    private T data = null;
    private List<MyTreeNode> children = new ArrayList<>();


    public MyTreeNode(T data) {
        this.data = data;

    }

    public void addChild(MyTreeNode child) {
        this.children.add(child);
    }

    public void addChild(T data) {
        MyTreeNode<T> newChild = new MyTreeNode<>(data);
        children.add(newChild);
    }

    public void addChildren(List<MyTreeNode> children) {
        this.children.addAll(children);
    }

    public List<MyTreeNode> getChildren() {
        return children;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }


}

Using the same example specified above,the output will be like this:

{ "data": "Root", "children": [ { "data": "Child1", "children": [ { "data": "Grandchild1", "children": [] }, { "data": "Grandchild2", "children": [] } ] }, { "data": "Child2", "children": [ { "data": "Grandchild3", "children": [] } ] }, { "data": "Child3", "children": [] }, { "data": "Child4", "children": [] }, { "data": "Child5", "children": [] }, { "data": "Child6", "children": [] } ] }

Actually, For me below works fine.

@Component
public class MyBean {

   public static String prop;

   @Value("${some.prop}")
   public void setProp(String prop) {
      this.prop= prop;
   }

   public MyBean() {

   }

   @PostConstruct
   public void init() {
      System.out.println("================== " + prop + "================== ");
   }

}

Now whereever i want, just invoke

MyBean.prop

it will return value.

It is ||, for example:

select 'Mr ' || ename from emp;

The only "interesting" feature I can think of is that 'x' || null returns 'x', not null as you might perhaps expect.

I think Henk nailed it with the "no sttatic access to the type system" thing

Another option is that there is no order to types where as numerics and strings can be. Thus a type switch would can't build a binary search tree, just a linear search.

You need to subscribe to the observable and pass a callback that processes emitted values

this.myService.getConfig().subscribe(val => console.log(val));

For Kotlin Users

You just need to add ? with Intent in onActivityResult as the data can be null if user cancels the transaction or anything goes wrong. So we need to define data as nullable in onActivityResult

Just replace onActivityResult signature of SampleActivity with below:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?)

The reason you don't have permissions to open file is because you didn't grant other apps to open or view the file on your intent. To grant other apps to open the downloaded file, include the flag(as shown below): FLAG_GRANT_READ_URI_PERMISSION

Intent browserIntent = new Intent(Intent.ACTION_VIEW);
browserIntent.setDataAndType(getUriFromFile(localFile), "application/pdf");
browserIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION|
Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(browserIntent);

And for function:

getUriFromFile(localFile)

private Uri getUriFromFile(File file){
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {
        return Uri.fromFile(file);
    }else {
        return FileProvider.getUriForFile(itemView.getContext(), itemView.getContext().getApplicationContext().getPackageName() + ".provider", file);
    }
}

You could use

new SimpleDateFormat( "yyyyMMdd" ).parse( "20100520" )

I also wanted to know why 2 GAC and found the following explanation by Mark Miller in the comments section of .NET 4.0 has 2 Global Assembly Cache (GAC):

Mark Miller said... June 28, 2010 12:13 PM

Thanks for the post. "Interference issues" was intentionally vague. At the time of writing, the issues were still being investigated, but it was clear there were several broken scenarios.

For instance, some applications use Assemby.LoadWithPartialName to load the highest version of an assembly. If the highest version was compiled with v4, then a v2 (3.0 or 3.5) app could not load it, and the app would crash, even if there were a version that would have worked. Originally, we partitioned the GAC under it's original location, but that caused some problems with windows upgrade scenarios. Both of these involved code that had already shipped, so we moved our (version-partitioned GAC to another place.

This shouldn't have any impact to most applications, and doesn't add any maintenance burden. Both locations should only be accessed or modified using the native GAC APIs, which deal with the partitioning as expected. The places where this does surface are through APIs that expose the paths of the GAC such as GetCachePath, or examining the path of mscorlib loaded into managed code.

It's worth noting that we modified GAC locations when we released v2 as well when we introduced architecture as part of the assembly identity. Those added GAC_MSIL, GAC_32, and GAC_64, although all still under %windir%\assembly. Unfortunately, that wasn't an option for this release.

Hope it helps future readers.

string[] files = 
    Directory.GetFiles(txtPath.Text, "*ProfileHandler.cs", SearchOption.AllDirectories);

That last parameter effects exactly what you're referring to. Set it to AllDirectories for every file including in subfolders, and set it to TopDirectoryOnly if you only want to search in the directory given and not subfolders.

Refer to MDSN for details: https://msdn.microsoft.com/en-us/library/ms143316(v=vs.110).aspx

If you are making apps that require dangerous permissions and set targetSDK to 23 or above you should be careful. If you do not check permissions on runtime you will get a SecurityException and if you are using code inside a try block, for example open camera, it can be hard to detect error if you do not check logcat.

Try this (it's VB-Code :-):

Try

Catch exp As WebException
  Dim sResponse As String = New StreamReader(exp.Response.GetResponseStream()).ReadToEnd
End Try

The second div is position: static (the default) so the z-index does not apply to it.

You need to position (set the position property to anything other than static, you probably want relative in this case) anything you want to give a z-index to.

This should work:

/^((?!PART).)*$/

If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:

/^(?!PART)/

Edit (by request): Why this pattern works

The (?!...) syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/." The site I've linked explains this far better than I can, but I'll try to break this down:

^         #Start matching from the beginning of the string.    
(?!PART)  #This position must not be followed by the string "PART".
.         #Matches any character except line breaks (it will include those in single-line mode).
$         #Match all the way until the end of the string.

The ((?!xxx).)* idiom is probably hardest to understand. As we saw, (?!PART) looks at the string ahead and says that whatever comes next can't match the subpattern /PART/. So what we're doing with ((?!xxx).)* is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.

The ^ and $ anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.

Since we do have ^ and $, if PART were anywhere in the string, one of the characters would match (?=PART). and the overall match would fail. Hope that's clear enough to be helpful.

There is really no way of "one-lining" what you are trying to do because toArray returns an Object[] and you cannot cast from Object[] to int[] or Integer[] to int[]

Use retainAll() in the Set interface. This method provides an intersection of elements common in both sets. See the API docs for more information.

I had a similar use case during testing hibernate event listeners which are only called on commit.

The solution was to wrap the code to be persistent into another method annotated with REQUIRES_NEW. (In another class) This way a new transaction is spawned and a flush/commit is issued once the method returns.

Keep in mind that this might influence all the other tests! So write them accordingly or you need to ensure that you can clean up after the test ran.

If I good understood this what is returned is fine except you want to see only one column. If so this below should be much simpler:

return Response::eloquent(Theme::with('user')->get(['username']));

var oldString = "stackoverflow";
var str=oldString.replace(/stackover/g,"NO");
$scope.newString= str;

It works for me. Use an intermediate variable.

If you just want to change file permissions, you want to be careful about using -R on chmod since it will change anything, files or folders. If you are doing a relative change (like adding write permission for everyone), you can do this:

sudo chmod -R a+w /var/www

But if you want to use the literal permissions of read/write, you may want to select files versus folders:

sudo find /var/www -type f -exec chmod 666 {} \;

(Which, by the way, for security reasons, I wouldn't recommend either of these.)

Or for folders:

sudo find /var/www -type d -exec chmod 755 {} \;

Cast table to Enumerable, then you call LINQ methods with using ToString() method inside:

    var example = contex.table_name.AsEnumerable()
.Select(x => new {Date = x.date.ToString("M/d/yyyy")...)

But be careful, when you calling AsEnumerable or ToList methods because you will request all data from all entity before this method. In my case above I read all table_name rows by one request.

I'd suggest using such extension method:

public static class DataColumnCollectionExtensions
{
    public static IEnumerable<DataColumn> AsEnumerable(this DataColumnCollection source)
    {
        return source.Cast<DataColumn>();
    }
}

And therefore:

string[] columnNames = dataTable.Columns.AsEnumerable().Select(column => column.Name).ToArray();

You may also implement one more extension method for DataTable class to reduce code:

public static class DataTableExtensions
{
    public static IEnumerable<DataColumn> GetColumns(this DataTable source)
    {
        return source.Columns.AsEnumerable();
    }
}

And use it as follows:

string[] columnNames = dataTable.GetColumns().Select(column => column.Name).ToArray();

The tool that richardtz suggests is excellent.

Another one that is amazing and comes with a 30 day free trial is Araxis Merge. This one does a 3 way merge and is much more feature complete than winmerge, but it is a commercial product.

You might also like to check out Scott Hanselman's developer tool list, which mentions a couple more in addition to winmerge

Put it this way

where ("R"."TIME_STAMP">=TO_DATE ('03-02-2013 00:00:00', 'DD-MM-YYYY HH24:MI:SS')
   AND "R"."TIME_STAMP"<=TO_DATE ('09-02-2013 23:59:59', 'DD-MM-YYYY HH24:MI:SS')) 

Where R is table name.
TIME_STAMP is FieldName in Table R.

Easiest explanation:

I held down the 'd' key for a second and then released.

dddddd

the keydown event happened once before the first d appeared on the screen, the keypress event happened 6 times and the keyup event happened after the last d appeared on the screen.

You can only manually delete properties of objects. Thus:

var container = {};

container.instance = new class();

delete container.instance;

However, this won't work on any other pointers. Therefore:

var container = {};

container.instance = new class();

var pointer = container.instance;

delete pointer; // false ( ie attempt to delete failed )

Furthermore:

delete container.instance; // true ( ie attempt to delete succeeded, but... )

pointer; // class { destroy: function(){} }

So in practice, deletion is only useful for removing object properties themselves, and is not a reliable method for removing the code they point to from memory.

A manually specified destroy method could unbind any event listeners. Something like:

function class(){
  this.properties = { /**/ }

  function handler(){ /**/ }

  something.addEventListener( 'event', handler, false );

  this.destroy = function(){
    something.removeEventListener( 'event', handler );
  }
}

It says that it should be a 64-bit JDK. I have a feeling that you installed (at a previous time) a 32-bit version of Java. The path for all 32-bit applications in Windows 7 and Vista is:

C:\Program Files (x86)\

You were setting the JAVA_HOME variable to the 32-bit version of Java. Set your JAVA_HOME variable to the following:

C:\Program Files\Java\jdk1.7.0_45

If that does not work, check that the JDK version is 1.7.0_45. If not, change the JAVA_HOME variable to (with JAVAVERSION as the Java version number:

C:\Program Files\Java\jdkJAVAVERSION

ETag is used to determine whether a resource should use the copy one. and Expires Header like Cache-Control is told the client that before the cache decades, client should fetch the local resource.

In modern sites, There are often offer a file named hash, like app.98a3cf23.js, so that it's a good practice to use Expires Header. Besides this, it also reduce the cost of network.

Hope it helps ;)

The question is about matplotlib, but for the sake of any R users that end up here given the language-agnostic title:

If you're using an R kernel, just use:

options(repr.plot.width=4, repr.plot.height=3)

I accidentally deleted a whole bunch of data in the wrong environment and this post was one of the first ones I found.

Because I was simultaneously panicking and searching for a solution, I went for the first thing I saw - ApexSQL Logs, which was $2000 which was an acceptable cost.

However, I've since found out that Toad for Sql Server can generate undo scripts from transaction logs and it is only $655.

Lastly, found an even cheaper option SysToolsGroup Log Analyzer and it is only $300.

Try this (demo):

.ui-autocomplete {
  position: absolute;
  top: 100%;
  left: 0;
  z-index: 1000;
  display: none;
  float: left;
  min-width: 160px;
  padding: 5px 0;
  margin: 2px 0 0;
  list-style: none;
  font-size: 14px;
  text-align: left;
  background-color: #ffffff;
  border: 1px solid #cccccc;
  border: 1px solid rgba(0, 0, 0, 0.15);
  border-radius: 4px;
  -webkit-box-shadow: 0 6px 12px rgba(0, 0, 0, 0.175);
  box-shadow: 0 6px 12px rgba(0, 0, 0, 0.175);
  background-clip: padding-box;
}

.ui-autocomplete > li > div {
  display: block;
  padding: 3px 20px;
  clear: both;
  font-weight: normal;
  line-height: 1.42857143;
  color: #333333;
  white-space: nowrap;
}

.ui-state-hover,
.ui-state-active,
.ui-state-focus {
  text-decoration: none;
  color: #262626;
  background-color: #f5f5f5;
  cursor: pointer;
}

.ui-helper-hidden-accessible {
  border: 0;
  clip: rect(0 0 0 0);
  height: 1px;
  margin: -1px;
  overflow: hidden;
  padding: 0;
  position: absolute;
  width: 1px;
}

I found that I could access the checkbox directly using Worksheets("SheetName").CB_Checkboxname.value directly without relating to additional objects.

Escape with a double backslash

R treats backslashes as escape values for character constants. (... and so do regular expressions. Hence the need for two backslashes when supplying a character argument for a pattern. The first one isn't actually a character, but rather it makes the second one into a character.) You can see how they are processed using cat.

y <- "double quote: \", tab: \t, newline: \n, unicode point: \u20AC"
print(y)
## [1] "double quote: \", tab: \t, newline: \n, unicode point: €"
cat(y)
## double quote: ", tab:    , newline: 
## , unicode point: €

Further reading: Escaping a backslash with a backslash in R produces 2 backslashes in a string, not 1

To use special characters in a regular expression the simplest method is usually to escape them with a backslash, but as noted above, the backslash itself needs to be escaped.

grepl("\\[", "a[b")
## [1] TRUE

To match backslashes, you need to double escape, resulting in four backslashes.

grepl("\\\\", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

The rebus package contains constants for each of the special characters to save you mistyping slashes.

library(rebus)
OPEN_BRACKET
## [1] "\\["
BACKSLASH
## [1] "\\\\"

For more examples see:

?SpecialCharacters

Your problem can be solved this way:

library(rebus)
grepl(OPEN_BRACKET, "a[b")

Form a character class

You can also wrap the special characters in square brackets to form a character class.

grepl("[?]", "a?b")
## [1] TRUE

Two of the special characters have special meaning inside character classes: \ and ^.

Backslash still needs to be escaped even if it is inside a character class.

grepl("[\\\\]", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

Caret only needs to be escaped if it is directly after the opening square bracket.

grepl("[ ^]", "a^b")  # matches spaces as well.
## [1] TRUE
grepl("[\\^]", "a^b") 
## [1] TRUE

rebus also lets you form a character class.

char_class("?")
## <regex> [?]

Use a pre-existing character class

If you want to match all punctuation, you can use the [:punct:] character class.

grepl("[[:punct:]]", c("//", "[", "(", "{", "?", "^", "$"))
## [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE

stringi maps this to the Unicode General Category for punctuation, so its behaviour is slightly different.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "[[:punct:]]")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

You can also use the cross-platform syntax for accessing a UGC.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "\\p{P}")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

Use \Q \E escapes

Placing characters between \\Q and \\E makes the regular expression engine treat them literally rather than as regular expressions.

grepl("\\Q.\\E", "a.b")
## [1] TRUE

rebus lets you write literal blocks of regular expressions.

literal(".")
## <regex> \Q.\E

Don't use regular expressions

Regular expressions are not always the answer. If you want to match a fixed string then you can do, for example:

grepl("[", "a[b", fixed = TRUE)
stringr::str_detect("a[b", fixed("["))
stringi::stri_detect_fixed("a[b", "[")

On Linux it's Monospace 10 pt. (the exact monospace font used may vary on different Linux distributions or versions), on Windows it's Consolas 10 pt., and on OS X it's Menlo Regular 12 pt.

^{(The color scheme is Neon, the syntax highlighting is from PackageDev, and the font is Liberation Mono}

This information is found in the Packages/Default directory (where Packages is the directory opened by the Preferences ? Browse Packages... menu option), in the Preferences (OS).sublime-settings file where OS is one of Windows, Linux, or OSX.

You should only customize the font (or any other setting) in Packages/User/Preferences.sublime-settings, opened by Preferences ? Settings—User, as Settings—Default is over-written on upgrade, and also serves as a backup in case you really screw something up in your user settings. This is the case for both the main Sublime settings as well as those for extra packages/plugins.

These default fonts are the same in Sublime Text 2, Sublime Text 3, and the new version currently in development.

Use cell arrays. This has an advantage over 3D arrays in that it does not require a contiguous memory space to store all the matrices. In fact, each matrix can be stored in a different space in memory, which will save you from Out-of-Memory errors if your free memory is fragmented. Here is a sample function to create your matrices in a cell array:

function result = createArrays(nArrays, arraySize)
    result = cell(1, nArrays);
    for i = 1 : nArrays
        result{i} = zeros(arraySize);
    end
end

To use it:

myArray = createArrays(requiredNumberOfArrays, [500 800]);

And to access your elements:

myArray{1}(2,3) = 10;

If you can't know the number of matrices in advance, you could simply use MATLAB's dynamic indexing to make the array as large as you need. The performance overhead will be proportional to the size of the cell array, and is not affected by the size of the matrices themselves. For example:

myArray{1} = zeros(500, 800);
if twoRequired, myArray{2} = zeros(500, 800); end

I had same issue after installing nvm-windows on top of existing Node installation. Solution was just to follow the instructions:

You should also delete the existing npm install location (e.g. "C:\Users\AppData\Roaming\npm") so that the nvm install location will be correctly used instead.

I found another very easy way to create dictionaries using itertools.

generator=itertools.combinations_with_replacement('abcd', 4 )

This will iterate through all combinations of 'a','b','c' and 'd' and create combinations with a total length of 1 to 4. ie. a,b,c,d,aa,ab.........,dddc,dddd. generator is an itertool object and you can loop through normally like this,

for password in generator:
        ''.join(password)

Each password is infact of type tuple and you can work on them as you normally do.

There's no need for Prototype here: JavaScript has for..in loops. If you're not sure that no one messed with Object.prototype, check hasOwnProperty() as well, ie

for(var prop in obj) {
    if(obj.hasOwnProperty(prop))
        doSomethingWith(obj[prop]);
}

If we're going to be as sloppy as to use tolower(), do this:

char blah[] = "blah blah Blah BLAH blAH\0"; int i=0; while(blah[i]|=' ', blah[++i]) {}

But, well, it kinda explodes if you feed it some symbols/numerals, and in general it's evil. Good interview question, though.

i am not sure but, I think you can use @ResponseEntity and @ResponseBody and send 2 different one is Success and second is error message like :

@RequestMapping(value ="/book2", produces =MediaType.APPLICATION_JSON_VALUE )
@ResponseBody
Book bookInfo2() {
    Book book = new Book();
    book.setBookName("Ramcharitmanas");
    book.setWriter("TulasiDas");
    return book;
}

@RequestMapping(value ="/book3", produces =MediaType.APPLICATION_JSON_VALUE )
public ResponseEntity<Book> bookInfo3() {
    Book book = new Book();
    book.setBookName("Ramayan");
    book.setWriter("Valmiki");
    return ResponseEntity.accepted().body(book);
}

If you're interested in type guarding an what would otherwise be a string (which is how I came across this issue), this might work for you:

enum CurrencyCode {
  cad = "cad",
  eur = "eur",
  gbp = "gbp",
  jpy = "jpy",
  usd = "usd",
}

const createEnumChecker = <T extends string, TEnumValue extends string>(
  enumVariable: { [key in T]: TEnumValue }
) => {
  const enumValues = Object.values(enumVariable);
  return (value: string | number | boolean): value is TEnumValue =>
    enumValues.includes(value);
};

const isCurrencyCode = createEnumChecker(CurrencyCode);

const input: string = 'gbp';

let verifiedCurrencyCode: CurrencyCode | null = null;
// verifiedCurrencyCode = input;
// ^ TypeError: Type 'string' is not assignable to type 'CurrencyCode | null'.

if (isCurrencyCode(input)) {
  verifiedCurrencyCode = input; // No Type Error 
}

Solution is taken from this github issue discussing generic Enums

Thank you all for your help.

This is what I have used in the end:

  END [Validate]

Updated Answer

Trying to open multiple panels of a collapse control that is setup as an accordion i.e. with the data-parent attribute set, can prove quite problematic and buggy (see this question on multiple panels open after programmatically opening a panel)

Instead, the best approach would be to:

1. Allow each panel to toggle individually
2. Then, enforce the accordion behavior manually where appropriate.

To allow each panel to toggle individually, on the data-toggle="collapse" element, set the data-target attribute to the .collapse panel ID selector (instead of setting the data-parent attribute to the parent control. You can read more about this in the question Modify Twitter Bootstrap collapse plugin to keep accordions open.

Roughly, each panel should look like this:

<div class="panel panel-default">
   <div class="panel-heading">
         <h4 class="panel-title"
             data-toggle="collapse" 
             data-target="#collapseOne">
             Collapsible Group Item #1
         </h4>
    </div>
    <div id="collapseOne" 
         class="panel-collapse collapse">
        <div class="panel-body"></div>
    </div>
</div>

To manually enforce the accordion behavior, you can create a handler for the collapse show event which occurs just before any panels are displayed. Use this to ensure any other open panels are closed before the selected one is shown (see this answer to multiple panels open). You'll also only want the code to execute when the panels are active. To do all that, add the following code:

$('#accordion').on('show.bs.collapse', function () {
    if (active) $('#accordion .in').collapse('hide');
});

Then use show and hide to toggle the visibility of each of the panels and data-toggle to enable and disable the controls.

$('#collapse-init').click(function () {
    if (active) {
        active = false;
        $('.panel-collapse').collapse('show');
        $('.panel-title').attr('data-toggle', '');
        $(this).text('Enable accordion behavior');
    } else {
        active = true;
        $('.panel-collapse').collapse('hide');
        $('.panel-title').attr('data-toggle', 'collapse');
        $(this).text('Disable accordion behavior');
    }
});

Try to use JSONP in your Ajax call. It will bypass the Same Origin Policy.

http://learn.jquery.com/ajax/working-with-jsonp/

Try example

$.ajax({
    url: "https://api.dailymotion.com/video/x28j5hv?fields=title",

    dataType: "jsonp",
    success: function( response ) {
        console.log( response ); // server response
    }

});

you can use skimage.img_as_ubyte(yourdata) it will make you numpy array ranges from 0->255

from skimage import img_as_ubyte

img = img_as_ubyte(data)

The R-squared is not dependent on the number of variables in the model. The adjusted R-squared is.

The adjusted R-squared adds a penalty for adding variables to the model that are uncorrelated with the variable your trying to explain. You can use it to test if a variable is relevant to the thing your trying to explain.

Adjusted R-squared is R-squared with some divisions added to make it dependent on the number of variables in the model.

My 2p solution:

#include <random>
#include <string>

std::string random_string(std::string::size_type length)
{
    static auto& chrs = "0123456789"
        "abcdefghijklmnopqrstuvwxyz"
        "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

    thread_local static std::mt19937 rg{std::random_device{}()};
    thread_local static std::uniform_int_distribution<std::string::size_type> pick(0, sizeof(chrs) - 2);

    std::string s;

    s.reserve(length);

    while(length--)
        s += chrs[pick(rg)];

    return s;
}

Single quotes are used to indicate the beginning and end of a string in SQL. Double quotes generally aren't used in SQL, but that can vary from database to database.

Stick to using single quotes.

That's the primary use anyway. You can use single quotes for a column alias — where you want the column name you reference in your application code to be something other than what the column is actually called in the database. For example: PRODUCT.id would be more readable as product_id, so you use either of the following:

• SELECT PRODUCT.id AS product_id
• SELECT PRODUCT.id 'product_id'

Either works in Oracle, SQL Server, MySQL… but I know some have said that the TOAD IDE seems to give some grief when using the single quotes approach.

You do have to use single quotes when the column alias includes a space character, e.g., product id, but it's not recommended practice for a column alias to be more than one word.

you can use the custom datetime by using...

 create table noteTable3 
 (created_at DATETIME DEFAULT (STRFTIME('%d-%m-%Y   %H:%M', 'NOW','localtime')),
 title text not null, myNotes text not null);

use 'NOW','localtime' to get the current system date else it will show some past or other time in your Database after insertion time in your db.

Thanks You...

There is a String.prototype.includes in ES6:

"potato".includes("to");
> true

Note that this does not work in Internet Explorer or some other old browsers with no or incomplete ES6 support. To make it work in old browsers, you may wish to use a transpiler like Babel, a shim library like es6-shim, or this polyfill from MDN:

if (!String.prototype.includes) {
  String.prototype.includes = function(search, start) {
    'use strict';
    if (typeof start !== 'number') {
      start = 0;
    }

    if (start + search.length > this.length) {
      return false;
    } else {
      return this.indexOf(search, start) !== -1;
    }
  };
}

The header <math.h> is a C std lib header. It defines a lot of stuff in the global namespace. The header <cmath> is the C++ version of that header. It defines essentially the same stuff in namespace std. (There are some differences, like that the C++ version comes with overloads of some functions, but that doesn't matter.) The header <cmath.h> doesn't exist.

Since vendors don't want to maintain two versions of what is essentially the same header, they came up with different possibilities to have only one of them behind the scenes. Often, that's the C header (since a C++ compiler is able to parse that, while the opposite won't work), and the C++ header just includes that and pulls everything into namespace std. Or there's some macro magic for parsing the same header with or without namespace std wrapped around it or not. To this add that in some environments it's awkward if headers don't have a file extension (like editors failing to highlight the code etc.). So some vendors would have <cmath> be a one-liner including some other header with a .h extension. Or some would map all includes matching <cblah> to <blah.h> (which, through macro magic, becomes the C++ header when __cplusplus is defined, and otherwise becomes the C header) or <cblah.h> or whatever.

That's the reason why on some platforms including things like <cmath.h>, which ought not to exist, will initially succeed, although it might make the compiler fail spectacularly later on.

I have no idea which std lib implementation you use. I suppose it's the one that comes with GCC, but this I don't know, so I cannot explain exactly what happened in your case. But it's certainly a mix of one of the above vendor-specific hacks and you including a header you ought not to have included yourself. Maybe it's the one where <cmath> maps to <cmath.h> with a specific (set of) macro(s) which you hadn't defined, so that you ended up with both definitions.

Note, however, that this code still ought not to compile:

#include <cmath>

double f(double d)
{
  return abs(d);
}

There shouldn't be an abs() in the global namespace (it's std::abs()). However, as per the above described implementation tricks, there might well be. Porting such code later (or just trying to compile it with your vendor's next version which doesn't allow this) can be very tedious, so you should keep an eye on this.

Instead of using the "c" tags, you could also do the following:

<h:outputLink value="Images/thumb_02.jpg" target="_blank" rendered="#{not empty user or user.userId eq 0}" />
<h:graphicImage value="Images/thumb_02.jpg" rendered="#{not empty user or user.userId eq 0}" />

<h:outputLink value="/DisplayBlobExample?userId=#{user.userId}" target="_blank" rendered="#{not empty user and user.userId neq 0}" />
<h:graphicImage value="/DisplayBlobExample?userId=#{user.userId}" rendered="#{not empty user and user.userId neq 0}"/>

I think that's a little more readable alternative to skuntsel's alternative answer and is utilizing the JSF rendered attribute instead of nesting a ternary operator. And off the answer, did you possibly mean to put your image in between the anchor tags so the image is clickable?

Be sure there is nothing on your button (such a div or a trasparent img) that keeps from clicking the button. It sounds stupid, but sometimes we think that jQuery is not working and all that stuffs and the problem is on the positioning of DOM elements.

In most of the general cases 'Length' and 'Count' are used.

Array:

int[] myArray = new int[size];
int noOfElements = myArray.Length;

Typed List Array:

List <int> myArray = new List<int>();
int noOfElements = myArray.Count;

You can check if the error is of type WebException and then inspect the response code;

if (e.Error.GetType().Name == "WebException")
{
   WebException we = (WebException)e.Error;
   HttpWebResponse response = (System.Net.HttpWebResponse)we.Response;
   if (response.StatusCode==HttpStatusCode.NotFound)
      System.Diagnostics.Debug.WriteLine("Not found!");
}

or

try
{
    // send request
}
catch (WebException e)
{
    // check e.Status as above etc..
}

Can I control the HTTP headers sent by window.open (cross browser)?

No

If not, can I somehow window.open a page that then issues my request with custom headers inside its popped-up window?

• You can request a URL that triggers a server side program which makes the request with arbitrary headers and then returns the response
• You can run JavaScript (probably saying goodbye to Progressive Enhancement) that uses XHR to make the request with arbitrary headers (assuming the URL fits within the Same Origin Policy) and then process the result in JS.

I need some cunning hacks...

It might help if you described the problem instead of asking if possible solutions would work.

Slightly different solution than HeatfanJohn's, where I change the zoom relatively to the current zoom level:

// Zoom out just a little
map.animateCamera(CameraUpdateFactory.zoomTo(map.getCameraPosition().zoom - 0.5f));

I found that I had to discover the inside of the extension method I was trying to mock the input for, and mock what was going on inside the extension.

I viewed using an extension as adding code directly to your method. This meant I needed to mock what happens inside the extension rather than the extension itself.

You can use numpy.recfromcsv(filename): the types of each column will be automatically determined (as if you use np.genfromtxt() with dtype=None), and by default delimiter=",". It's basically a shortcut for np.genfromtxt(filename, delimiter=",", dtype=None) that Pierre GM pointed at in his answer.

SRCS=$(wildcard *.c)

OBJS=$(SRCS:.c=.o)

all: $(OBJS)

This one works fine for me :

theme.applyStyle(R.style.AppTheme, true)

Usage:

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    //The call goes right after super.onCreate() and before setContentView()
    theme.applyStyle(R.style.AppTheme, true)
    setContentView(layoutId)
    onViewCreated(savedInstanceState)
}

The function takes a pointer to an arbitrary type and returns one such.

PHP error_reporting reference:

// Turn off all error reporting
error_reporting(0);

// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);

// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings ...)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);

// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);

// Report all PHP errors (see changelog)
error_reporting(E_ALL);

// Report all PHP errors
error_reporting(-1);

// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);

List can be instantiated by any class implementing the interface.By this way,Java provides us polymorphic behaviour.See the example below:

List<String> list = new ArrayList<String>();

Instead of instantiating an ArrayList directly,I am using a List to refer to ArrayList object so that we are using only the List interface methods and do not care about its actual implementation.

Examples of classes implementing List are ArrayList,LinkedList,Vector.You probably want to create a List depending upon your requirements.

Example:- a LinkedList is more useful when you hve to do a number of inertion or deletions .Arraylist is more performance intensive as it is backed by a fixed size array and array contents have to be changed by moving or regrowing the array.

Again,using a List we can simply change our object instantiation without changing any code further in your programs.

Suppose we are using ArrayList<String> value = new ArrayList<String>();

we may use a specific method of ArrrayList and out code will not be robust

By using List<String> value = new ArrayList<String>();

we are making sure we are using only List interface methods..and if we want to change it to a LinkedList we simply have to change the code :

List<String> value = new ArrayList<String>(); 

------ your code uses List interface methods.....

value = new LinkedList<String>(); 

-----your code still uses List interface methods and we do not have to change anything---- and we dont have to change anything in our code further

By the way a LinkedList also works a Deque which obviously also you cannot instantiate as it is also an interface

There are several causes for this error.

MySQL/MariaDB related:

• wait_timeout - Time in seconds that the server waits for a connection to become active before closing it.
• interactive_timeout - Time in seconds that the server waits for an interactive connection.
• max_allowed_packet - Maximum size in bytes of a packet or a generated/intermediate string. Set as large as the largest BLOB, in multiples of 1024.

Example of my.cnf:

[mysqld]
# 8 hours
wait_timeout = 28800
# 8 hours
interactive_timeout = 28800
max_allowed_packet = 256M

Server related:

• Your server has full memory - check info about RAM with free -h

Framework related:

• Check settings of your framework. Django for example use CONN_MAX_AGE (see docs)

How to debug it:

• Check values of MySQL/MariaDB variables.
  • with sql: SHOW VARIABLES LIKE '%time%';
  • command line: mysqladmin variables
• Turn on verbosity for errors:
  • MariaDB: log_warnings = 4
  • MySQL: log_error_verbosity = 3
• Check docs for more info about the error

You can do something like this:

import sys
from PIL import Image

images = [Image.open(x) for x in ['Test1.jpg', 'Test2.jpg', 'Test3.jpg']]
widths, heights = zip(*(i.size for i in images))

total_width = sum(widths)
max_height = max(heights)

new_im = Image.new('RGB', (total_width, max_height))

x_offset = 0
for im in images:
  new_im.paste(im, (x_offset,0))
  x_offset += im.size[0]

new_im.save('test.jpg')

Test1.jpg

Test2.jpg

Test3.jpg

test.jpg

The nested for for i in xrange(0,444,95): is pasting each image 5 times, staggered 95 pixels apart. Each outer loop iteration pasting over the previous.

for elem in list_im:
  for i in xrange(0,444,95):
    im=Image.open(elem)
    new_im.paste(im, (i,0))
  new_im.save('new_' + elem + '.jpg')

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />
