LE: I just remembered this was about using Google Maps, so my answer doesn't really answer the initial question, but I hope some people will save hours/days banging their heads on their desks if they have the same issue with Play Game Services.

I too had this incredibly cryptic error. It wasn't anything related to location services for me, but with not properly reading the documentation, more precisely step 3, where it says to add the following to your AndroidManifest.xml:

<meta-data android:name="com.google.android.gms.games.APP_ID"
    android:value="@string/app_id" />

You should obviously also have the following in AndroidManifest.xml

<meta-data android:name="com.google.android.gms.version"
   android:value="@integer/google_play_services_version"/>

I was using the BaseGameActivity they suggest to use when you want to implement game services so I was a bit surprised it didn't work straight away. I did create a dedicated module for a copy of the google-play-services_lib, I did have the latest version of it (4323000 as of writing) and I did set this as a module dependency to my main module (using Android Studio here). But that little line above fixed everything.

Assuming it is OK that the operation is not atomic, you can do:

if (std::ifstream(name))
{
     std::cout << "File already exists" << std::endl;
     return false;
}
std::ofstream file(name);
if (!file)
{
     std::cout << "File could not be created" << std::endl;
     return false;
}
... 

Note that this doesn't work if you run multiple threads trying to create the same file, and certainly will not prevent a second process from "interfering" with the file creation because you have TOCTUI problems. [We first check if the file exists, and then create it - but someone else could have created it in between the check and the creation - if that's critical, you will need to do something else, which isn't portable].

A further problem is if you have permissions such as the file is not readable (so we can't open it for read) but is writeable, it will overwrite the file.

In MOST cases, neither of these things matter, because all you care about is telling someone that "you already have a file like that" (or something like that) in a "best effort" approach.

append() creates a new array which can be the old array with the appended element.

I think it's more normal to use the proper method for adding an element:

a = numpy.append(a, a[0])

Try this:
#ifdef _WIN64
// 64 bit code
#elif _WIN32
// 32 bit code
#else
   if(sizeof(void*)==4)

       // 32 bit code
   else 

       // 64 bit code   
#endif

Summarised form an answer to Xcode fails with "Code Signing" Error

project.pbxproj files can be merged in such a way that two CODE_SIGN_IDENTITY lines can be inserted. Deleting one of these normally fixes the issue.

I have created simple script to help diagnose this issue it can be found here: https://gist.github.com/4339226

A full answer can be found here.

bool isBigEndian()
{
    static const uint16_t m_endianCheck(0x00ff);
    return ( *((uint8_t*)&m_endianCheck) == 0x0); 
}

#!/bin/bash -e

x='2018-01-18 10:00:00'
a=$(date -d "$x")
b=$(date -d "$a 10 min" "+%Y-%m-%d %H:%M:%S")
c=$(date -d "$b 10 min" "+%Y-%m-%d %H:%M:%S")
#date -d "$a 30 min" "+%Y-%m-%d %H:%M:%S"

echo Entered Date is $x
echo Second Date is $b
echo Third Date is $c

Here x is sample date used & then example displays both formatting of data as well as getting dates 10 mins more then current date.

In python>3 you can use print and * for argument unpacking:

with open("fout.txt", "w") as fout:
    print(*my_list, sep="\n", file=fout)

This worked for me:

HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) + HttpRuntime.AppDomainAppVirtualPath + "ImageName";

The short version can be like this:

const diff = (a, b) => b.filter((i) => a.indexOf(i) === -1);

result:

diff(['a', 'b'], ['a', 'b', 'c', 'd']);

["c", "d"]

If you want to replace an arbitrary sequence of blank characters (tab, space) with one comma, use the following:

sed 's/[\t ]+/,/g' input_file > output_file

or

sed -r 's/[[:blank:]]+/,/g' input_file > output_file

If some of your input lines include leading space characters which are redundant and don't need to be converted to commas, then first you need to get rid of them, and then convert the remaining blank characters to commas. For such case, use the following:

sed 's/ +//' input_file | sed 's/[\t ]+/,/g' > output_file

Please note that if you made changes to textarea, after it had rendered; You will get the updated value instead of the initialized value.

<!doctype html>
<html lang="en">
    <head>
        <script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
        <script>
            $(function () {
                $('#btnShow').click(function () {
                    alert('text:' + $('#addressFieldName').text() + '\n value:' + $('#addressFieldName').val());
                });
            });
            function updateAddress() {
                $('#addressFieldName').val('District: Peshawar \n');
            }
        </script>
    </head>
    <body>
        <?php
        $address = "School: GCMHSS NO.1\nTehsil: ,\nDistrict: Haripur";
        ?>
        <textarea id="addressFieldName" rows="4" cols="40" tabindex="5" ><?php echo $address; ?></textarea>
        <?php echo '<script type="text/javascript">updateAddress();</script>'; ?>
        <input type="button" id="btnShow" value='show' />
    </body>
</html>

As you can see the value of textarea will be different than the text in between the opening and closing tag of concern textarea.

Mutable changes the meaning of const from bitwise const to logical const for the class.

This means that classes with mutable members are longer be bitwise const and will no longer appear in read-only sections of the executable.

Furthermore, it modifies type-checking by allowing const member functions to change mutable members without using const_cast.

class Logical {
    mutable int var;

public:
    Logical(): var(0) {}
    void set(int x) const { var = x; }
};

class Bitwise {
    int var;

public:
    Bitwise(): var(0) {}
    void set(int x) const {
        const_cast<Bitwise*>(this)->var = x;
    }
};

const Logical logical; // Not put in read-only.
const Bitwise bitwise; // Likely put in read-only.

int main(void)
{
    logical.set(5); // Well defined.
    bitwise.set(5); // Undefined.
}

See the other answers for more details but I wanted to highlight that it isn't merely for type-saftey and that it affects the compiled result.

You can use the ng-value directive in a hidden field as below :-

<input type="hidden" ng-value="myScopeVar = someValue"/>

This will set the value of the scope variable (myScopeVar) to "someValue"

In my case it doesn't work, even with __DIR__ or getcwd() it keeps picking the wrong path, I solved by defining a costant in every file I need with the absolute base path of the project:

if(!defined('THISBASEPATH')){ define('THISBASEPATH', '/mypath/'); }
require_once THISBASEPATH.'cache/crud.php';
/*every other require_once you need*/

I have MAMP with php 5.4.10 and my folder hierarchy is basilar:

q.php 
w.php 
e.php 
r.php 
cache/a.php 
cache/b.php 
setting/a.php 
setting/b.php

....

The question is how to pass argument from child to parent component. This example is easy to use and tested:

//Child component
class Child extends React.Component {
    render() {
        var handleToUpdate  =   this.props.handleToUpdate;
        return (<div><button onClick={() => handleToUpdate('someVar')}>Push me</button></div>
        )
    }
}

//Parent component
class Parent extends React.Component {
    constructor(props) {
        super(props);
        var handleToUpdate  = this.handleToUpdate.bind(this);
    }

    handleToUpdate(someArg){
        alert('We pass argument from Child to Parent: \n' + someArg);
    }

    render() {
        var handleToUpdate  =   this.handleToUpdate;
        return (<div>
          <Child handleToUpdate = {handleToUpdate.bind(this)} />
        </div>)
    }
}

if(document.querySelector("#demo")){
    ReactDOM.render(
        <Parent />,
        document.querySelector("#demo")
    );
}

Look at JSFIDDLE

If your method is related to the object's characteristics, you should define it as non-static method. Otherwise, you can define your method as static, and you can use it independently from object.

you should use []

var x = ConfigurationManager.AppSettings["APIKey"];

char c = 'A';
printf("ptr: %p,\tvalue: %c,\tand also address: %zu", &c, c, &c);

Result:

ptr: 0x7ffc48e5105f,    value: A,    and also address: 140721531457631

One practical difference is that browsers and webservers have a limit on the number of characters that can exist in a URL. It's different from application to application, but it's certainly possible to hit it if you've got textareas in your forms.

Another gotcha with GETs - they get indexed by search engines and other automatic systems. Google once had a product that would pre-fetch links on the page you were viewing, so they'd be faster to load if you clicked those links. It caused major havoc on sites that had links like delete.php?id=1 - people lost their entire sites.

For those of us still lagging behind on Swift 2.3 here is Gordon's answer in our syntax:

let email = "[email protected]"
if let url = NSURL(string: "mailto:\(email)") {
   UIApplication.sharedApplication().openURL(url)
}

that's probably about pricing model... ;)

OK here is what worked for me! I have a button on my left Nav. If you click it it will open a window and that window will load a document. After loading the document I want print the document then close the popup window immediately.

contentDiv.focus();
contentDiv.contentWindow.print();
contentDiv.contentWindow.onfocus = function() {
    window.close();
};

Why does this work?
Well, after printing you set the onfocus event to close the window. The print popup will load so quickly that the onfocus event will not get a chance to trigger until you 1)print 2) cancel the print. Once you regain focus on the window, the window will close!
I hope that will work for you

The li tag has a property called list-style-position. This makes your bullets inside or outside the list. On default, it’s set to inside. That makes your text wrap around it. If you set it to outside, the text of your li tags will be aligned.

The downside of that is that your bullets won't be aligned with the text outside the ul. If you want to align it with the other text you can use a margin.

ul li {
    /*
     * We want the bullets outside of the list,
     * so the text is aligned. Now the actual bullet
     * is outside of the list’s container
     */
    list-style-position: outside;

    /*
     * Because the bullet is outside of the list’s
     * container, indent the list entirely
     */
    margin-left: 1em;
}

Edit 15th of March, 2014 Seeing people are still coming in from Google, I felt like the original answer could use some improvement

• Changed the code block to provide just the solution
• Changed the indentation unit to em’s
• Each property is applied to the ul element
• Good comments :)

Apache 2.4 virtual hosts hack

1.In http.conf specify the ports , below “Listen”

Listen 80
Listen 4000
Listen 7000
Listen 9000

2. In httpd-vhosts.conf

   <VirtualHost *:80>
   ServerAdmin [email protected]
   DocumentRoot "C:/Users/Vikas/Documents/NetBeansProjects/slider_website_hitesh/public_html"  
   ServerName hitesh_web.dev
   ErrorLog "logs/dummy-host2.example.com-error.log"
   CustomLog "logs/dummy-host2.example.com-access.log" common
   
   <Directory "C:/Users/Vikas/Documents/NetBeansProjects/slider_website_hitesh/public_html">
   Allow from all
   Require all granted
   </Directory>
   
   </VirtualHost>
   

   this is 2nd virtual host

   <VirtualHost *:80>
   ServerAdmin [email protected]
   DocumentRoot "E:/dabkick_git/DabKickWebsite"
   ServerName  www.my_mobile.dev
   ErrorLog "logs/dummy-host2.example.com-error.log"
   CustomLog "logs/dummy-host2.example.com-access.log" common
   
   <Directory "E:/dabkick_git/DabKickWebsite">
    Allow from all
    Require all granted
    </Directory>
   </VirtualHost>
   

3. In hosts.ics file of windows os “C:\Windows\System32\drivers\etc\host.ics”

   127.0.0.1             localhost
   127.0.0.1             hitesh_web.dev
   127.0.0.1             www.my_mobile.dev
   127.0.0.1             demo.multisite.dev
   

4.now type your “domain names” in the browser it will ping the particular folder specified in the documentRoot path

5.if you want to access those files in a particular port then replace 80 in httpd-vhosts.conf with port numbers like below and restart apache

   <VirtualHost *:4000>
ServerAdmin [email protected]
DocumentRoot "C:/Users/Vikas/Documents/NetBeansProjects/slider_website_hitesh/public_html"
ServerName hitesh_web.dev
ErrorLog "logs/dummy-host2.example.com-error.log"
CustomLog "logs/dummy-host2.example.com-access.log" common

<Directory "C:/Users/Vikas/Documents/NetBeansProjects/slider_website_hitesh/public_html">
Allow from all
Require all granted
</Directory>

</VirtualHost>

this is the 2nd vhost

<VirtualHost *:7000>
ServerAdmin [email protected]
DocumentRoot "E:/dabkick_git/DabKickWebsite"
ServerName  www.dabkick_mobile.dev
ErrorLog "logs/dummy-host2.example.com-error.log"
CustomLog "logs/dummy-host2.example.com-access.log" common

<Directory "E:/dabkick_git/DabKickWebsite">
Allow from all
Require all granted
</Directory>
</VirtualHost>

Note: for port number given virtual hosts you have to ping in browser like “http://hitesh_web.dev:4000/” or “http://www.dabkick_mobile.dev:7000/”

6.After doing all those changes you have to save the files and restart apache respectively.

Place your script inside the body tag

<body>
  // Rest of html
  <script>
  function hideButton() {
    $(".loading").hide();
  }
function showButton() {
  $(".loading").show();
}
</script> 
< /body>

If you check this JSFIDDLE and click on javascript, you will see the load Type body is selected

Since PHP 5.1.0, file_put_contents() supports writing piece-by-piece by passing a stream-handle as the $data parameter:

file_put_contents("Tmpfile.zip", fopen("http://someurl/file.zip", 'r'));

From the manual:

If data [that is the second argument] is a stream resource, the remaining buffer of that stream will be copied to the specified file. This is similar with using stream_copy_to_stream().

(Thanks Hakre.)

Well, WelcomeMessage is just a variable name for message (actual model with data). Basically, you are binding the model with the welcomePage here. The Model (message) will be available in welcomePage.jsp as WelcomeMessage. Here is a simpler example:

ModelAndView("hello","myVar", "Hello World!");

In this case, my model is a simple string (In applications this will be a POJO with data fetched for DB or other sources.). I am assigning it to myVar and my view is hello.jsp. Now, myVar is available for me in hello.jsp and I can use it for display.

In the view, you can access the data though:

${myVar}

Similarly, You will be able to access the model through WelcomeMessage variable.

This is mostly an upgrade to Jorenko's answer, that allows to use parameters with spaces in Windows, but should also work fairly well on Linux :) Also, will work with cx_freeze or py2exe since we don't use __file__ but sys.argv[0] as executable

import sys,ctypes,platform

def is_admin():
    try:
        return ctypes.windll.shell32.IsUserAnAdmin()
    except:
        raise False

if __name__ == '__main__':

    if platform.system() == "Windows":
        if is_admin():
            main(sys.argv[1:])
        else:
            # Re-run the program with admin rights, don't use __file__ since py2exe won't know about it
            # Use sys.argv[0] as script path and sys.argv[1:] as arguments, join them as lpstr, quoting each parameter or spaces will divide parameters
            lpParameters = ""
            # Litteraly quote all parameters which get unquoted when passed to python
            for i, item in enumerate(sys.argv[0:]):
                lpParameters += '"' + item + '" '
            try:
                ctypes.windll.shell32.ShellExecuteW(None, "runas", sys.executable, lpParameters , None, 1)
            except:
                sys.exit(1)
    else:
        main(sys.argv[1:])

<html>    
    <input type="text" placeholder ="username" id="userinput">
    <br>
    <input type="password" placeholder="password">
    <br>
    <button type="submit" onclick="myfunc()" id="demo">click me</button>

    <script type="text/javascript">
        function myfunc() {
            var input = document.getElementById('userinput');
            alert(input.value);
        } 
    </script>
</html>

There is obviously another process listening on the port. You might find out that process by using the following command:

$ lsof -i :8000

or change your tornado app's port. tornado's error info not Explicitly on this.

From arrays

An array is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created. After creation, its length is fixed. You've seen an example of arrays already, in the main method of the "Hello World!" application. This section discusses arrays in greater detail.

So in the case of a String array, once you create it with some length, you can't modify it, but you can add elements until you fill it.

String[] arr = new String[10]; // 10 is the length of the array.
arr[0] = "kk";
arr[1] = "pp";
...

So if your requirement is to add many objects, it's recommended that you use Lists like:

List<String> a = new ArrayList<String>();
a.add("kk");
a.add("pp"); 

In c and C++ there is no data type called BOOLEAN Thats why it uses 1 and 0 as true false value. and in JAVA 1 and 0 are count as an INTEGER type so it produces error in java. And java have its own boolean values true and false with boolean data type.

happy programming..

Here are a variety of shell scripts you can use to strip out different elements.

# doctype
find . -regex ".*\.\(html\|py\)$" -type f -exec sed -i "s/<\!DOCTYPE\s\+html[^>]*>/<\!DOCTYPE html>/gi" {} \;

# meta charset
find . -regex ".*\.\(html\|py\)$" -type f -exec sed -i "s/<meta[^>]*content=[\"'][^\"']*utf-8[\"'][^>]*>/<meta charset=\"utf-8\">/gi" {} \;

# script text/javascript
find . -regex ".*\.\(html\|py\)$" -type f -exec sed -i "s/\(<script[^>]*\)\(\stype=[\"']text\/javascript[\"']\)\(\s\?[^>]*>\)/\1\3/gi" {} \;

# style text/css
find . -regex ".*\.\(html\|py\)$" -type f -exec sed -i "s/\(<style[^>]*\)\(\stype=[\"']text\/css[\"']\)\(\s\?[^>]*>\)/\1\3/gi" {} \;

# html xmlns
find . -regex ".*\.\(html\|py\)$" -type f -exec sed -i "s/\(<html[^>]*\)\(\sxmlns=[\"'][^\"']*[\"']\)\(\s\?[^>]*>\)/\1\3/gi" {} \;

# html xml:lang
find . -regex ".*\.\(html\|py\)$" -type f -exec sed -i "s/\(<html[^>]*\)\(\sxml:lang=[\"'][^\"']*[\"']\)\(\s\?[^>]*>\)/\1\3/gi" {} \;

Premise

There is no standard naming of keys in JSON. According to the Objects section of the spec:

The JSON syntax does not impose any restrictions on the strings used as names,...

Which means camelCase or snake_case should work fine.

Driving factors

Imposing a JSON naming convention is very confusing. However, this can easily be figured out if you break it down into components.

1. Programming language for generating JSON

   • Python - snake_case
   • PHP - snake_case
   • Java - camelCase
   • JavaScript - camelCase

2. JSON itself has no standard naming of keys

3. Programming language for parsing JSON

   • Python - snake_case
   • PHP - snake_case
   • Java - camelCase
   • JavaScript - camelCase

Mix-match the components

1. Python » JSON » Python - snake_case - unanimous
2. Python » JSON » PHP - snake_case - unanimous
3. Python » JSON » Java - snake_case - please see the Java problem below
4. Python » JSON » JavaScript - snake_case will make sense; screw the front-end anyways
5. Python » JSON » you do not know - snake_case will make sense; screw the parser anyways
6. PHP » JSON » Python - snake_case - unanimous
7. PHP » JSON » PHP - snake_case - unanimous
8. PHP » JSON » Java - snake_case - please see the Java problem below
9. PHP » JSON » JavaScript - snake_case will make sense; screw the front-end anyways
10. PHP » JSON » you do not know - snake_case will make sense; screw the parser anyways
11. Java » JSON » Python - snake_case - please see the Java problem below
12. Java » JSON » PHP - snake_case - please see the Java problem below
13. Java » JSON » Java - camelCase - unanimous
14. Java » JSON » JavaScript - camelCase - unanimous
15. Java » JSON » you do not know - camelCase will make sense; screw the parser anyways
16. JavaScript » JSON » Python - snake_case will make sense; screw the front-end anyways
17. JavaScript » JSON » PHP - snake_case will make sense; screw the front-end anyways
18. JavaScript » JSON » Java - camelCase - unanimous
19. JavaScript » JSON » JavaScript - camelCase - Original

Java problem

snake_case will still make sense for those with Java entries because the existing JSON libraries for Java are using only methods to access the keys instead of using the standard dot.syntax. This means that it wouldn't hurt that much for Java to access the snake_cased keys in comparison to the other programming language which can do the dot.syntax.

Example for Java's org.json package

JsonObject.getString("snake_cased_key")

Example for Java's com.google.gson package

JsonElement.getAsString("snake_cased_key")

Some actual implementations

• Google Maps JavaScript API - camelCased
• Facebook JavaScript API - snake_cased
• Amazon Web Services - snake_cased & camelCased
• Twitter API - snake_cased
• JSON-LD - camelCased & ProperCamelCased

Conclusions

Choosing the right JSON naming convention for your JSON implementation depends on your technology stack. There are cases where one can use snake_case, camelCase, or any other naming convention.

Another thing to consider is the weight to be put on the JSON-generator vs the JSON-parser and/or the front-end JavaScript. In general, more weight should be put on the JSON-generator side rather than the JSON-parser side. This is because business logic usually resides on the JSON-generator side.

Also, if the JSON-parser side is unknown then you can declare what ever can work for you.

The reason for the special treatment of "id" is that it is added to the default route mapping. To change this, go to Global.asax.cs, and you will find the following line:

routes.MapRoute ("Default", "{controller}/{action}/{id}", 
                 new { controller = "Home", action = "Index", id = "" });

Change it to:

routes.MapRoute ("Default", "{controller}/{action}", 
                 new { controller = "Home", action = "Index" });

I know as for Appium Mobile Automation you need .app file to run ios app on Simulator.So as like me many of you face this problem. So I explain how to create that .app file and where it is located.

1.Open Xcode.

2.Click on your sample project.(If you don't have then click on create new xcode project)

3.In left panel inside screen you will see products folder then click and expand that, you will see the list.

4. Then right click on .app file and click on Show in Finder and thats your .app file. Now you can copy or use that path in capabilities for appium desktop or in framework.

1. Configure PHP build to produce xml junit report

   <phpunit bootstrap="tests/bootstrap.php" colors="true" >
      <logging>
          <log type="junit" target="build/junit.xml" 
              logIncompleteSkipped="false" title="Test Results"/>
      </logging>
   
      ....
   
    </phpunit>
   

2. Finish build script with status 0

   ...
   exit 0;

4. Add Jenkins Text Finder plugin with console output scanning and unchecked options. This plugin fail whole build on fatal error.

   PHP Fatal error:
   

I had the same problem on 11.201 on Windows. After: additional install 11.203 64bit server and client in new folders. PATH environment variable was changed right after install. Error in listener appeared after listener service restart. In my case there was a night time and number of windows updates, so windows server restart helped us. Also I cleaned listener.log file according to http://pavandba.com/tag/tns-12560-tns-protocol-adapter-error/, it was surprisingly big.

As distribute has been merged back into setuptools, it is now recommended to install/upgrade setuptools instead:

[sudo] pip install --upgrade setuptools

Here's a variation of Oscar's first version that doesn't use a for-each loop.

for (int i = 0; i < charArray.length; i++) {
    if (charArray[i] == 'q') {
        // do something
        break;
    }
}

You could have a boolean variable that gets set to false before the loop, then make "do something" set the variable to true, which you could test for after the loop. The loop could also be wrapped in a function call then just use 'return true' instead of the break, and add a 'return false' statement after the for loop.

This is what I do on mine

$(document).ready(function() {
  if ($('#userForm').valid()) {
    var formData = $("#userForm").serializeArray();
    $.ajax({
      url: 'http://www.example.com/user/' + $('#Id').val() + '?callback=?',
      type: "GET",
      data: formData,
      dataType: "jsonp",
      jsonpCallback: "localJsonpCallback"
    });
  });

function localJsonpCallback(json) {
  if (!json.Error) {
    $('#resultForm').submit();
  } else {
    $('#loading').hide();
    $('#userForm').show();
    alert(json.Message);
  }
}

It is actually quite easy to do this, if you are using android.support.v7 library.

Step - 1

Declare a menu item

<item android:id="@+id/action_search"
    android:title="Search"
    android:icon="@drawable/abc_ic_search_api_mtrl_alpha"
    app:showAsAction="ifRoom|collapseActionView"
    app:actionViewClass="android.support.v7.widget.SearchView" />

Step - 2

Extend AppCompatActivity and in the onCreateOptionsMenu setup the SearchView.

import android.support.v7.widget.SearchView;

...

public class YourActivity extends AppCompatActivity {

    ...

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_home, menu);
        // Retrieve the SearchView and plug it into SearchManager
        final SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));
        SearchManager searchManager = (SearchManager) getSystemService(SEARCH_SERVICE);
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        return true;
    }

    ... 

}

Result

I've defined the following property as we use this often in unit testing.

public static string AssemblyDirectory
{
    get
    {
        string codeBase = Assembly.GetExecutingAssembly().CodeBase;
        UriBuilder uri = new UriBuilder(codeBase);
        string path = Uri.UnescapeDataString(uri.Path);
        return Path.GetDirectoryName(path);
    }
}

The Assembly.Location property sometimes gives you some funny results when using NUnit (where assemblies run from a temporary folder), so I prefer to use CodeBase which gives you the path in URI format, then UriBuild.UnescapeDataString removes the File:// at the beginning, and GetDirectoryName changes it to the normal windows format.

I had this error when running an old python script developped with Python 2.6.4

When updating to 3.6.2, I had to remove all 'rb' parameters from open calls in order to fix this csv reading error.

In our case we wanted to compile Vagrant version and had same error. We fixed it by clean project and rebuild project in Build menu

With SharePoint 2013 new library, I managed to do something like this:

private void UploadToSharePoint(string p, out string newUrl)  //p is path to file to load
{
    string siteUrl = "https://myCompany.sharepoint.com/site/";
    //Insert Credentials
    ClientContext context = new ClientContext(siteUrl);

    SecureString passWord = new SecureString();
    foreach (var c in "mypassword") passWord.AppendChar(c);
    context.Credentials = new SharePointOnlineCredentials("myUserName", passWord);
    Web site = context.Web;

    //Get the required RootFolder
    string barRootFolderRelativeUrl = "Shared Documents/foo/bar";
    Folder barFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl);

    //Create new subFolder to load files into
    string newFolderName = baseName + DateTime.Now.ToString("yyyyMMddHHmm");
    barFolder.Folders.Add(newFolderName);
    barFolder.Update();

    //Add file to new Folder
    Folder currentRunFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl + "/" + newFolderName);
    FileCreationInformation newFile = new FileCreationInformation { Content = System.IO.File.ReadAllBytes(@p), Url = Path.GetFileName(@p), Overwrite = true };
    currentRunFolder.Files.Add(newFile);
    currentRunFolder.Update();

    context.ExecuteQuery();

    //Return the URL of the new uploaded file
    newUrl = siteUrl + barRootFolderRelativeUrl + "/" + newFolderName + "/" + Path.GetFileName(@p);
}

This solution may good for looking

var some_other_function = someVar => function() {
}

someObj.addEventListener('click', some_other_function(someVar));

or bind valiables will be also good

Python 3:

import urllib.request

wp = urllib.request.urlopen("http://google.com")
pw = wp.read()
print(pw)

Python 2:

import urllib
import sys

wp = urllib.urlopen("http://google.com")
for line in wp:
    sys.stdout.write(line)

While I have tested both the Codes in respective versions.

Step 1: Highlight the entire column (not including the header) of the column you wish to populate

Step 2: (Using Kutools) On the Insert dropdown, click "Fill Custom List"

Step 3: Click Edit

Step 4: Create your list (For Ex: 1, 2)

Step 5: Choose your new custom list and then click "Fill Range"

DONE!!!

These answers are all very good, but I wanted to share another thing I discovered on stackoverflow that is really quite useful, here is the direct link

Basically, @DidzisElferts shows how you can get all the colours, coordinates, etc that ggplot uses to build a plot you created. Very nice!

p <- ggplot(mpg,aes(x=class,fill=class)) + geom_bar()
ggplot_build(p)$data
[[1]]
     fill  y count x ndensity ncount  density PANEL group ymin ymax xmin xmax

$(editFrame).contents().find("html").html();

One more solution is

Rails.application.routes.routes

Try this, note that you don't need to specify the end index in substring.

var characters = member.substr(member.length -2);

Yes, what you are asking for is called AJAX or XMLHttpRequest. You can either use a library like jQuery to simplify making the call (due to cross-browser compatibility issues), or write your own handler.

In jQuery:

$.GET('url.asp', {data: 'here'}, function(data){ /* what to do with the data returned */ })

In plain vanilla javaScript (from w3c):

var xmlhttp;
function loadXMLDoc(url)
{
    xmlhttp=null;
if (window.XMLHttpRequest)
  {// code for all new browsers
      xmlhttp=new XMLHttpRequest();
  }
else if (window.ActiveXObject)
  {// code for IE5 and IE6
      xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
if (xmlhttp!=null)
  {
      xmlhttp.onreadystatechange=state_Change;
      xmlhttp.open("GET",url,true);
      xmlhttp.send(null);
  }
else
  {
      alert("Your browser does not support XMLHTTP.");
  }
}

function state_Change()
{
    if (xmlhttp.readyState==4)
      {// 4 = "loaded"
          if (xmlhttp.status==200)
            {// 200 = OK
             //xmlhttp.data and shtuff
            // ...our code here...
        }
  else
        {
            alert("Problem retrieving data");
        }
  }
}

Try this sample SQL scripts for easy understanding,

CREATE TABLE TABLE1 (REFNO VARCHAR(10))
CREATE TABLE TABLE2 (REFNO VARCHAR(10))

--TRUNCATE TABLE TABLE1
--TRUNCATE TABLE TABLE2

INSERT INTO TABLE1 SELECT 'TEST_NAME'
INSERT INTO TABLE1 SELECT 'KUMAR'
INSERT INTO TABLE1 SELECT 'SIVA'
INSERT INTO TABLE1 SELECT 'SUSHANT'

INSERT INTO TABLE2 SELECT 'KUMAR'
INSERT INTO TABLE2 SELECT 'SIVA'
INSERT INTO TABLE2 SELECT 'SUSHANT'

SELECT * FROM TABLE1
SELECT * FROM TABLE2

DELETE T1 FROM TABLE1 T1 JOIN TABLE2 T2 ON T1.REFNO = T2.REFNO

Your case is:

   DELETE pgc
     FROM guide_category pgc 
LEFT JOIN guide g
       ON g.id_guide = gc.id_guide 
    WHERE g.id_guide IS NULL

With async actions (timers, ajax) you can override the property isDefaultPrevented like this:

$('a').click(function(evt){
  e.preventDefault();

  // in async handler (ajax/timer) do these actions:
  setTimeout(function(){
    // override prevented flag to prevent jquery from discarding event
    evt.isDefaultPrevented = function(){ return false; }
    // retrigger with the exactly same event data
    $(this).trigger(evt);
  }, 1000);
}

This is most complete way of retriggering the event with the exactly same data.

echo date('Y-m-d H:i:s.') . gettimeofday()['usec'];

output:

2016-11-19 15:12:34.346351

// The letter "t" is usually letter "i"//

    for(t=0;t<x[t];t++)
    {

         printf(" %2d          || %7d \n ",t,x[t]);
    }

I wouldnt use this attribute as most browsers ignore it as CMS points out.

By all means use client side validation but only in conjunction with server side. Any client side validation can be got round.

Slightly off topic but some people check the content type to validate the uploaded file. You need to be careful about this as an attacker can easily change it and upload a php file for example. See the example at: http://www.scanit.be/uploads/php-file-upload.pdf

Rob R.'s answer was definitely the way to go. I tried copying the ic_launcher.png files from another project and Eclipse still wouldn't read them. Going through the manifest is much quicker and easier.

With React-Native 0.56, the above method of changing Text.prototype.render does not work anymore, so you have to use your own component, which can be done in one line!

MyText.js

export default props => <Text {...props} style={[{fontFamily: 'Helvetica'}, props.style]}>{props.children}</Text>

AnotherComponent.js

import Text from './MyText';

...
<Text>This will show in default font.</Text>
...

Nowadays, it's better to use queues than threads (for those who don't use Laravel there are tons of other implementations out there like this).

The basic idea is, your original PHP script puts tasks or jobs into a queue. Then you have queue job workers running elsewhere, taking jobs out of the queue and starts processing them independently of the original PHP.

The advantages are:

1. Scalability - you can just add worker nodes to keep up with demand. In this way, tasks are run in parallel.
2. Reliability - modern queue managers such as RabbitMQ, ZeroMQ, Redis, etc, are made to be extremely reliable.

you could also use this:

public static class Extensions
 {

        public static string RemovePrefix(this string o, string prefix)
        {
            if (prefix == null) return o;
            return !o.StartsWith(prefix) ? o : o.Remove(0, prefix.Length);
        }

        public static string RemoveSuffix(this string o, string suffix)
        {
            if(suffix == null) return o;
            return !o.EndsWith(suffix) ? o : o.Remove(o.Length - suffix.Length, suffix.Length);
        }

    }

The following snippet will print "REGISTER here"

$string = "REGISTER 11223344 here";

$result = preg_replace(
   array('/(\d+)/'),
   array(''),
   $string
);

print_r($result);

The preg_replace() API usage us as given below.

$result = preg_replace(
    array('/pattern1/', '/pattern2/'),
    array('replace1', 'replace2'),
    $input_string
);

There should be a binary called "pip2.7" installed at some location included within your $PATH variable.

You can find that out by typing

which pip2.7

This should print something like '/usr/local/bin/pip2.7' to your stdout. If it does not print anything like this, it is not installed. In that case, install it by running

$ wget https://bootstrap.pypa.io/get-pip.py
$ sudo python2.7 get-pip.py

Now, you should be all set, and

which pip2.7

should return the correct output.

I used accepted answer reference and would like to put an example, since Angular 2 documentation is very very hard to read, I hope this is easier:

1. Import NgZone:

   import { Component, NgZone } from '@angular/core';
   

2. Add it to your class constructor

   constructor(public zone: NgZone, ...args){}
   

3. Run code with zone.run:

   this.zone.run(() => this.donations = donations)
   

MonoDevelop, the IDE associated with Mono Project should be enough for C# development on Linux. Now I don't know any good profilers and other tools for C# development on Linux. But then again mind you, that C# is a language more native to windows. You are better developing C# apps for windows than for linux.

EDIT: When you download MonoDevelop from the Ubuntu Software Center, it will contain pretty much everything you need to get started right away (Compiler, Runtime Environment, IDE). If you would like more information, see the following links:

• http://monodevelop.com/
• http://en.wikipedia.org/wiki/MonoDevelop
• http://en.wikipedia.org/wiki/Mono_%28software%29
• http://www.mono-project.com/Development_Environments

You have to figure out if the string is ascii encoded or encoded with a multi-byte format.

In the former case, you can just use strlen.

In the latter case you need to find the number of bytes per character.

the strlen documentation gives an example of how to do it : http://www.php.net/manual/en/function.strlen.php#72274

A large reason is that video games require direct knowledge of the hardware underneath, often times, and there really is no great implementation for many architectures. It's the knowledge of the underlying hardware architecture that allows developers to squeeze every ounce of performance out of a gaming system. Why would you take the time to port Java to a gaming platform, and then write a game on top of that port when you could just write the game?

edit: this is to say that it's more than a "speed" or "don't have the right libraries" issue. Those two things go hand-in-hand with this, but it's more a matter of "how do I make a system like the cell b.e. run my java code? there aren't really any good java compilers that can manage the pipelines and vectors like i need.."

Lazy notes in comments.

#include <stdio.h>

You don't need to apply to_date() to sysdate. It is already there:

select 1
from dual 
WHERE sysdate BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND TO_DATE('20/06/2014', 'DD/MM/YYYY');

If you are concerned about the time component on the date, then use trunc():

select 1
from dual 
WHERE trunc(sysdate) BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND
                             TO_DATE('20/06/2014', 'DD/MM/YYYY');

@owlstead, regarding your request for "a cryptographically secure variant of one of the given answers," please see RNCryptor. It was designed to do exactly what you're requesting (and was built in response to the problems with the code listed here).

RNCryptor uses PBKDF2 with salt, provides a random IV, and attaches HMAC (also generated from PBKDF2 with its own salt. It support synchronous and asynchronous operation.

For streaming protocols such as TCP, you can pretty much set your buffer to any size. That said, common values that are powers of 2 such as 4096 or 8192 are recommended.

If there is more data then what your buffer, it will simply be saved in the kernel for your next call to recv.

Yes, you can keep growing your buffer. You can do a recv into the middle of the buffer starting at offset idx, you would do:

recv(socket, recv_buffer + idx, recv_buffer_size - idx, 0);

inline and inline-block elements are affected by whitespace in the HTML.

The simplest way to fix your problem is to remove the whitespace between </div> and <div id="col2">, see: http://jsfiddle.net/XCDsu/15/

There are other possible solutions, see: bikeshedding CSS3 property alternative?

You can imitate open source Dockerfile, for example:

Node: node12-github

RUN groupadd --gid 1000 node \
    && useradd --uid 1000 --gid node --shell /bin/bash --create-home node

superset: superset-github

RUN useradd --user-group --create-home --no-log-init --shell /bin/bash

I think it's a good way to follow open source.

As described in this answer, you can easily create your own selector for hasText. This allows you to find the option with $('#test').find('option:hastText("B")').val();

Here's the hasText method I added:

 if( ! $.expr[':']['hasText'] ) {
     $.expr[':']['hasText'] = function( node, index, props ) {
       var retVal = false;
       // Verify single text child node with matching text
       if( node.nodeType == 1 && node.childNodes.length == 1 ) {
         var childNode = node.childNodes[0];
         retVal = childNode.nodeType == 3 && childNode.nodeValue === props[3];
       }
       return retVal;
     };
  }

In Visual Studio please click 'Folder.ico' file in the Solution Explorer pane. Then you will see Properties pane. Change 'Copy to Output Directory' behavior to 'Copy if newer'. This will make Visual Studio copy the file to the output bin directory.

Now to get the file path using relative path just type:

string pathToIcoFile = AppDomain.CurrentDomain.BaseDirectory + "//FolderIcon//Folder.ico";

Hope that helped.

if (strtotime($date) > mktime(0,0,0)) should do the job.

According to https://git-scm.com/docs/git-log, for more pretty output in console you can use --decorate argument of git-log command:

git log --pretty=oneline --decorate

will print:

This seems like an old thread, but I'll add my experience here. I tried to install a cert as well and got that error. I then opened the cer file with a txt editor, and noticed that there is an extra space (character) at the end of each line. Removing those lines allowed me to import the cert.

Hope this is worth something to someone else.

I faced the same problem. You just have to make it an array and moreover you have to put double squared brackets to make it a single element of the 2D array as first bracket initializes the array and the second makes it an element of that array.

So simply replace the last statement by:

print(clf.predict(np.array[[0.58,0.76]]))

(class/ID):after {
content:none;
}

Always works for me class or ID can be for a div or even body causing the white space.

This answer attempts to address inputs with an absolute value in the range of 2147483648₁₀ (2³¹) – 9007199254740991₁₀ (2⁵³-1).

In JavaScript, numbers are stored in 64-bit floating point representation, but bitwise operations coerce them to 32-bit integers in two's complement format, so any approach which uses bitwise operations restricts the range of output to -2147483648₁₀ (-2³¹) – 2147483647₁₀ (2³¹-1).

However, if bitwise operations are avoided and the 64-bit floating point representation is preserved by using only mathematical operations, we can reliably convert any safe integer to 64-bit two's complement binary notation by sign-extending the 53-bit twosComplement:

function toBinary (value) {
  if (!Number.isSafeInteger(value)) {
    throw new TypeError('value must be a safe integer');
  }

  const negative = value < 0;
  const twosComplement = negative ? Number.MAX_SAFE_INTEGER + value + 1 : value;
  const signExtend = negative ? '1' : '0';

  return twosComplement.toString(2).padStart(53, '0').padStart(64, signExtend);
}

function format (value) {
  console.log(value.toString().padStart(64));
  console.log(value.toString(2).padStart(64));
  console.log(toBinary(value));
}

format(8);
format(-8);
format(2**33-1);
format(-(2**33-1));
format(2**53-1);
format(-(2**53-1));
format(2**52);
format(-(2**52));
format(2**52+1);
format(-(2**52+1));

For older browsers, polyfills exist for the following functions and values:

• Number.isSafeInteger()
• Number.isInteger()
• Number.MAX_SAFE_INTEGER
• String.prototype.padStart()

As an added bonus, you can support any radix (2–36) if you perform the two's complement conversion for negative numbers in ?64 / log₂(radix)? digits by using BigInt:

function toRadix (value, radix) {
  if (!Number.isSafeInteger(value)) {
    throw new TypeError('value must be a safe integer');
  }

  const digits = Math.ceil(64 / Math.log2(radix));
  const twosComplement = value < 0
    ? BigInt(radix) ** BigInt(digits) + BigInt(value)
    : value;

  return twosComplement.toString(radix).padStart(digits, '0');
}

console.log(toRadix(0xcba9876543210, 2));
console.log(toRadix(-0xcba9876543210, 2));
console.log(toRadix(0xcba9876543210, 16));
console.log(toRadix(-0xcba9876543210, 16));
console.log(toRadix(0x1032547698bac, 2));
console.log(toRadix(-0x1032547698bac, 2));
console.log(toRadix(0x1032547698bac, 16));
console.log(toRadix(-0x1032547698bac, 16));

Not sure if this will help somebody else out or not but this was the key part to fix my problem in user "Tom Hawtin - tacklin"'s answer above:

synchronized (lock) {
    makeWakeupNeeded();
    lock.notifyAll();
}

Just the fact that the "lock" is passed as an argument in synchronized() and it is also used in "lock".notifyAll();

Once I made it in those 2 places I got it working

This will show you clues about why the linker doesn't want the installed library:

LD_DEBUG=all make ...

I had the same problem in a different context: my system /lib/libz.so.1 had unsatisfied dependencies on libc because I was trying to relink on a different version of the OS.

These alternative libraries worked for me:

sudo apt-get update
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6

If you have a ADO.Net DataTable you could do

int sum = 0;
foreach(DataRow dr in dataTable.Rows)
{
   sum += Convert.ToInt32(dr["Amount"]);
}

If you want to query the database table, you could use

Select Sum(Amount) From DataTable

This MSDN blog post describes three separate ways of extracting a DLL from the GAC. A useful summary of the methods so far given.

Rab's answer works great, but not for Microsoft Edge, so I added a small adaptation for Edge as well:

https://jsfiddle.net/et9borp4/

function insertAtCursor(myField, myValue) {
    //IE support
    if (document.selection) {
        myField.focus();
        sel = document.selection.createRange();
        sel.text = myValue;
    }
    // Microsoft Edge
    else if(window.navigator.userAgent.indexOf("Edge") > -1) {
      var startPos = myField.selectionStart; 
      var endPos = myField.selectionEnd; 

      myField.value = myField.value.substring(0, startPos)+ myValue 
             + myField.value.substring(endPos, myField.value.length); 

      var pos = startPos + myValue.length;
      myField.focus();
      myField.setSelectionRange(pos, pos);
    }
    //MOZILLA and others
    else if (myField.selectionStart || myField.selectionStart == '0') {
        var startPos = myField.selectionStart;
        var endPos = myField.selectionEnd;
        myField.value = myField.value.substring(0, startPos)
            + myValue
            + myField.value.substring(endPos, myField.value.length);
    } else {
        myField.value += myValue;
    }
}

It's worth noting that an OS has one queue for both System.err and System.out. Consider the following code:

public class PrintQueue {
    public static void main(String[] args) {
        for(int i = 0; i < 100; i++) {
            System.out.println("out");
            System.err.println("err");
        }
    }
}

If you compile and run the program, you will see that the order of outputs in console is mixed up.

An OS will remain right order if you work either with System.out or System.err only. But it can randomly choose what to print next to console, if you use both of these.

Even in this code snippet you can see that the order is mixed up sometimes:

public class PrintQueue {
    public static void main(String[] args) {
        System.out.println("out");
        System.err.println("err");
    }
}

Every variable in python (stuff like dict1 or str or __builtins__ is a pointer to some hidden platonic "object" inside the machine.

If you set dict1 = dict2,you just point dict1 to the same object (or memory location, or whatever analogy you like) as dict2. Now, the object referenced by dict1 is the same object referenced by dict2.

You can check: dict1 is dict2 should be True. Also, id(dict1) should be the same as id(dict2).

You want dict1 = copy(dict2), or dict1 = deepcopy(dict2).

The difference between copy and deepcopy? deepcopy will make sure that the elements of dict2 (did you point it at a list?) are also copies.

I don't use deepcopy much - it's usually poor practice to write code that needs it (in my opinion).

I have not used Recyclerview but I did it on ListView. Sample code in Recyclerview:

setOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        rowPos = mLayoutManager.findFirstVisibleItemPosition();

It is the listener when user is scrolling. The performance overhead is not significant. And the first visible position is accurate this way.

The answers above are good. Adding a case that I used. Just if you don't want to use numpy and keep it as list without changing the contents.

You can run a small loop and change the dimension from 1xN to Nx1.

    tmp=[]
    for b in bus:
        tmp.append([b])
    bus=tmp

It is maybe not efficient while in case of very large numbers. But it works for a small set of numbers. Thanks

Here's a LESS mixin for transitioning two properties at once:

.transition-two(@transition1, @transition1-duration, @transition2, @transition2-duration) {
 -webkit-transition: @transition1 @transition1-duration, @transition2 @transition2-duration;
    -moz-transition: @transition1 @transition1-duration, @transition2 @transition2-duration;
      -o-transition: @transition1 @transition1-duration, @transition2 @transition2-duration;
          transition: @transition1 @transition1-duration, @transition2 @transition2-duration;
}

Try this :

public void addTeacherToClassRoom(classroom myClassRoom, String TeacherName)
{
    myClassRoom.setTeacherName(TeacherName);
}

The bracket stuff (e.g., [[ $a -gt $b ]] or (( $a > $b )) ) isn't enough if you want to use float numbers as well; it would report a syntax error. If you want to compare float numbers or float number to integer, you can use (( $(bc <<< "...") )).

For example,

a=2.00
b=1

if (( $(bc <<<"$a > $b") )); then 
    echo "a is greater than b"
else
    echo "a is not greater than b"
fi

You can include more than one comparison in the if statement. For example,

a=2.
b=1
c=1.0000

if (( $(bc <<<"$b == $c && $b < $a") )); then 
    echo "b is equal to c but less than a"
else
    echo "b is either not equal to c and/or not less than a"
fi

That's helpful if you want to check if a numeric variable (integer or not) is within a numeric range.

 NSTimer.scheduledTimerWithTimeInterval(NSTimeInterval(3), target: self, selector: "functionHere", userInfo: nil, repeats: false)

This would call the function functionHere() with a 3 seconds delay

Such is how I have it embedded and outputted to my HTML web page:

<div class="container">

            document.write(CurrentYear)
        </script>
    </p>
</div>

Output to HTML page is as follows:

If it's in a class, you can use getattr:

class MyClass(object):
    def install(self):
          print "In install"

method_name = 'install' # set by the command line options
my_cls = MyClass()

method = None
try:
    method = getattr(my_cls, method_name)
except AttributeError:
    raise NotImplementedError("Class `{}` does not implement `{}`".format(my_cls.__class__.__name__, method_name))

method()

or if it's a function:

def install():
       print "In install"

method_name = 'install' # set by the command line options
possibles = globals().copy()
possibles.update(locals())
method = possibles.get(method_name)
if not method:
     raise NotImplementedError("Method %s not implemented" % method_name)
method()

You'll have to set it to zero. Zero means the script can run forever. Add the following at the start of your script:

ini_set('max_execution_time', 0);

Refer to the PHP documentation of max_execution_time

Note that:

set_time_limit(0);

will have the same effect.

This is an old question but none of the previous answers has addressed the real issue, i.e. that fact that the problem is with the question itself.

First, if the probabilities have been already calculated, i.e. the histogram aggregated data is available in a normalized way then the probabilities should add up to 1. They obviously do not and that means that something is wrong here, either with terminology or with the data or in the way the question is asked.

Second, the fact that the labels are provided (and not intervals) would normally mean that the probabilities are of categorical response variable - and a use of a bar plot for plotting the histogram is best (or some hacking of the pyplot's hist method), Shayan Shafiq's answer provides the code.

However, see issue 1, those probabilities are not correct and using bar plot in this case as "histogram" would be wrong because it does not tell the story of univariate distribution, for some reason (perhaps the classes are overlapping and observations are counted multiple times?) and such plot should not be called a histogram in this case.

Histogram is by definition a graphical representation of the distribution of univariate variable (see Histogram | NIST/SEMATECH e-Handbook of Statistical Methods & Histogram | Wikipedia) and is created by drawing bars of sizes representing counts or frequencies of observations in selected classes of the variable of interest. If the variable is measured on a continuous scale those classes are bins (intervals). Important part of histogram creation procedure is making a choice of how to group (or keep without grouping) the categories of responses for a categorical variable, or how to split the domain of possible values into intervals (where to put the bin boundaries) for continuous type variable. All observations should be represented, and each one only once in the plot. That means that the sum of the bar sizes should be equal to the total count of observation (or their areas in case of the variable widths, which is a less common approach). Or, if the histogram is normalised then all probabilities must add up to 1.

If the data itself is a list of "probabilities" as a response, i.e. the observations are probability values (of something) for each object of study then the best answer is simply plt.hist(probability) with maybe binning option, and use of x-labels already available is suspicious.

Then bar plot should not be used as histogram but rather simply

import matplotlib.pyplot as plt
probability = [0.3602150537634409, 0.42028985507246375, 
  0.373117033603708, 0.36813186813186816, 0.32517482517482516, 
  0.4175257731958763, 0.41025641025641024, 0.39408866995073893, 
  0.4143222506393862, 0.34, 0.391025641025641, 0.3130841121495327, 
  0.35398230088495575]
plt.hist(probability)
plt.show()

with the results

matplotlib in such case arrives by default with the following histogram values

(array([1., 1., 1., 1., 1., 2., 0., 2., 0., 4.]),
 array([0.31308411, 0.32380469, 0.33452526, 0.34524584, 0.35596641,
        0.36668698, 0.37740756, 0.38812813, 0.39884871, 0.40956928,
        0.42028986]),
 <a list of 10 Patch objects>)

the result is a tuple of arrays, the first array contains observation counts, i.e. what will be shown against the y-axis of the plot (they add up to 13, total number of observations) and the second array are the interval boundaries for x-axis.

One can check they they are equally spaced,

x = plt.hist(probability)[1]
for left, right in zip(x[:-1], x[1:]):
  print(left, right, right-left)

Or, for example for 3 bins (my judgment call for 13 observations) one would get this histogram

plt.hist(probability, bins=3)

with the plot data "behind the bars" being

The author of the question needs to clarify what is the meaning of the "probability" list of values - is the "probability" just a name of the response variable (then why are there x-labels ready for the histogram, it makes no sense), or are the list values the probabilities calculated from the data (then the fact they do not add up to 1 makes no sense).

If you want to add a single column after a specific field, then the following MySQL query should work:

ALTER TABLE users
    ADD COLUMN count SMALLINT(6) NOT NULL
    AFTER lastname

If you want to add multiple columns, then you need to use 'ADD' command each time for a column. Here is the MySQL query for this:

ALTER TABLE users
    ADD COLUMN count SMALLINT(6) NOT NULL,
    ADD COLUMN log VARCHAR(12) NOT NULL,
    ADD COLUMN status INT(10) UNSIGNED NOT NULL
    AFTER lastname

Point to note

In the second method, the last ADD COLUMN column should actually be the first column you want to append to the table.

E.g: if you want to add count, log, status in the exact order after lastname, then the syntax would actually be:

ALTER TABLE users
    ADD COLUMN log VARCHAR(12) NOT NULL AFTER lastname,
    ADD COLUMN status INT(10) UNSIGNED NOT NULL AFTER lastname,
    ADD COLUMN count SMALLINT(6) NOT NULL AFTER lastname
    

I really wanted this (placeholders should look the same for text boxes as select boxes!) and straight CSS wasn't working in Chrome. Here is what I did:

First make sure your select tag has a .has-prompt class.

Then initialize this class somewhere in document.ready.

# Adds a class to select boxes that have prompt currently selected.
# Allows for placeholder-like styling.
# Looks for has-prompt class on select tag.
Mess.Views.SelectPromptStyler = Backbone.View.extend
  el: 'body'

  initialize: ->
    @$('select.has-prompt').trigger('change')

  events:
    'change select.has-prompt': 'changed'

  changed: (e) ->
    select = @$(e.currentTarget)
    if select.find('option').first().is(':selected')
      select.addClass('prompt-selected')
    else
      select.removeClass('prompt-selected')

Then in CSS:

select.prompt-selected {
  color: $placeholder-color;
}

Here is the linked list version of a queue that also includes the last node, as suggested by @perkins and as is most appropriate.

// QUEUE Object Definition

var Queue = function() {
  this.first = null;
  this.last = null;
  this.size = 0;
};

var Node = function(data) {
  this.data = data;
  this.next = null;
};

Queue.prototype.enqueue = function(data) {
  var node = new Node(data);

  if (!this.first){ // for empty list first and last are the same
    this.first = node;
    this.last = node;
  } else { // otherwise we stick it on the end
    this.last.next=node;
    this.last=node;
  }

  this.size += 1;
  return node;
};

Queue.prototype.dequeue = function() {
  if (!this.first) //check for empty list
    return null;

  temp = this.first; // grab top of list
  if (this.first==this.last) {
    this.last=null;  // when we need to pop the last one
  }
  this.first = this.first.next; // move top of list down
  this.size -= 1;
  return temp;
};

"How does this and $scope work in AngularJS controllers?"

Short answer:

• this
  • When the controller constructor function is called, this is the controller.
  • When a function defined on a $scope object is called, this is the "scope in effect when the function was called". This may (or may not!) be the $scope that the function is defined on. So, inside the function, this and $scope may not be the same.
• $scope
  • Every controller has an associated $scope object.
  • A controller (constructor) function is responsible for setting model properties and functions/behaviour on its associated $scope.
  • Only methods defined on this $scope object (and parent scope objects, if prototypical inheritance is in play) are accessible from the HTML/view. E.g., from ng-click, filters, etc.

Long answer:

A controller function is a JavaScript constructor function. When the constructor function executes (e.g., when a view loads), this (i.e., the "function context") is set to the controller object. So in the "tabs" controller constructor function, when the addPane function is created

this.addPane = function(pane) { ... }

it is created on the controller object, not on $scope. Views cannot see the addPane function -- they only have access to functions defined on $scope. In other words, in the HTML, this won't work:

<a ng-click="addPane(newPane)">won't work</a>

After the "tabs" controller constructor function executes, we have the following:

The dashed black line indicates prototypal inheritance -- an isolate scope prototypically inherits from Scope. (It does not prototypically inherit from the scope in effect where the directive was encountered in the HTML.)

Now, the pane directive's link function wants to communicate with the tabs directive (which really means it needs to affect the tabs isolate $scope in some way). Events could be used, but another mechanism is to have the pane directive require the tabs controller. (There appears to be no mechanism for the pane directive to require the tabs $scope.)

So, this begs the question: if we only have access to the tabs controller, how do we get access to the tabs isolate $scope (which is what we really want)?

Well, the red dotted line is the answer. The addPane() function's "scope" (I'm referring to JavaScript's function scope/closures here) gives the function access to the tabs isolate $scope. I.e., addPane() has access to the "tabs IsolateScope" in the diagram above because of a closure that was created when addPane() was defined. (If we instead defined addPane() on the tabs $scope object, the pane directive would not have access to this function, and hence it would have no way to communicate with the tabs $scope.)

To answer the other part of your question: how does $scope work in controllers?:

Within functions defined on $scope, this is set to "the $scope in effect where/when the function was called". Suppose we have the following HTML:

<div ng-controller="ParentCtrl">
   <a ng-click="logThisAndScope()">log "this" and $scope</a> - parent scope
   <div ng-controller="ChildCtrl">
      <a ng-click="logThisAndScope()">log "this" and $scope</a> - child scope
   </div>
</div>

And the ParentCtrl (Solely) has

$scope.logThisAndScope = function() {
    console.log(this, $scope)
}

Clicking the first link will show that this and $scope are the same, since "the scope in effect when the function was called" is the scope associated with the ParentCtrl.

Clicking the second link will reveal this and $scope are not the same, since "the scope in effect when the function was called" is the scope associated with the ChildCtrl. So here, this is set to ChildCtrl's $scope. Inside the method, $scope is still the ParentCtrl's $scope.

Fiddle

I try to not use this inside of a function defined on $scope, as it becomes confusing which $scope is being affected, especially considering that ng-repeat, ng-include, ng-switch, and directives can all create their own child scopes.

there are three ways you can use: the RETURN value, and OUTPUT parameter and a result set

ALSO, watch out if you use the pattern: SELECT @Variable=column FROM table ...

if there are multiple rows returned from the query, your @Variable will only contain the value from the last row returned by the query.

RETURN VALUE
since your query returns an int field, at least based on how you named it. you can use this trick:

CREATE PROCEDURE GetMyInt
( @Param int)
AS
DECLARE @ReturnValue int

SELECT @ReturnValue=MyIntField FROM MyTable WHERE MyPrimaryKeyField = @Param
RETURN @ReturnValue
GO

and now call your procedure like:

DECLARE @SelectedValue int
       ,@Param         int
SET @Param=1
EXEC @SelectedValue = GetMyInt @Param
PRINT @SelectedValue

this will only work for INTs, because RETURN can only return a single int value and nulls are converted to a zero.

OUTPUT PARAMETER
you can use an output parameter:

CREATE PROCEDURE GetMyInt
( @Param     int
 ,@OutValue  int OUTPUT)
AS
SELECT @OutValue=MyIntField FROM MyTable WHERE MyPrimaryKeyField = @Param
RETURN 0
GO

and now call your procedure like:

DECLARE @SelectedValue int
       ,@Param         int
SET @Param=1
EXEC GetMyInt @Param, @SelectedValue OUTPUT
PRINT @SelectedValue 

Output parameters can only return one value, but can be any data type

RESULT SET for a result set make the procedure like:

CREATE PROCEDURE GetMyInt
( @Param     int)
AS
SELECT MyIntField FROM MyTable WHERE MyPrimaryKeyField = @Param
RETURN 0
GO

use it like:

DECLARE @ResultSet table (SelectedValue int)
DECLARE @Param int
SET @Param=1
INSERT INTO @ResultSet (SelectedValue)
    EXEC GetMyInt @Param
SELECT * FROM @ResultSet 

result sets can have many rows and many columns of any data type

I have a blog and I had a lot of trouble finding out how to resize my embedded gist. Post manager only allows you to write text, place images and embed HTML code. Blog layout is responsive itself. It's built with Wix. However, embedded HTML is not. I read a lot about how it's impossible to resize components inside body of generated iFrames. So, here is my suggestion:

If you only have one component inside your iFrame, i.e. your gist, you can resize only the gist. Forget about the iFrame.

I had problems with viewport, specific layouts to different user agents and this is what solved my problem:

<script language="javascript" type="text/javascript" src="https://gist.github.com/roliveiravictor/447f994a82238247f83919e75e391c6f.js"></script>

<script language="javascript" type="text/javascript">

function windowSize() {
  let gist = document.querySelector('#gist92442763');

  let isMobile = {
    Android: function() {
        return /Android/i.test(navigator.userAgent)
    },
    BlackBerry: function() {
        return /BlackBerry/i.test(navigator.userAgent)
    },
    iOS: function() {
        return /iPhone|iPod/i.test(navigator.userAgent)
    },
    Opera: function() {
        return /Opera Mini/i.test(navigator.userAgent)
    },
    Windows: function() {
        return /IEMobile/i.test(navigator.userAgent) || /WPDesktop/i.test(navigator.userAgent)
    },
    any: function() {
        return (isMobile.Android() || isMobile.BlackBerry() || isMobile.iOS() || isMobile.Opera() || isMobile.Windows());
    }
};

  if(isMobile.any()) {
    gist.style.width = "36%";
    gist.style.WebkitOverflowScrolling = "touch"
    gist.style.position = "absolute"
  } else {
    gist.style.width = "auto !important";
  }
}

windowSize();

window.addEventListener('onresize', function() {
    windowSize();
});

</script>

<style type="text/css">

.gist-data {
  max-height: 300px;
}

.gist-meta {
  display: none;
}

</style>

The logic is to set gist (or your component) css based on user agent. Make sure to identify your component first, before applying to query selector. Feel free to take a look how responsiveness is working.

A notice about IList: MSDN IList Remarks: "IList implementations fall into three categories: read-only, fixed-size, and variable-size. (...). For the generic version of this interface, see System.Collections.Generic.IList<T>."

IList<T> does NOT inherits from IList (but List<T> does implement both IList<T> and IList), but is always variable-size. Since .NET 4.5, we have also IReadOnlyList<T> but AFAIK, there is no fixed-size generic List which would be what you are looking for.

Try this puglin simpleUpload, no need form

Html:

<input type="file" name="arquivo" id="simpleUpload" multiple >
<button type="button" id="enviar">Enviar</button>

$('#simpleUpload').simpleUpload({
  url: 'upload.php',
  trigger: '#enviar',
  success: function(data){
    alert('Envio com sucesso');

  }
});

As you probably figured out, the issue is that you are trying to allocate one large contiguous block of memory, which does not work due to memory fragmentation. If I needed to do what you are doing I would do the following:

int sizeA = 10000,
    sizeB = 10000;
double sizeInMegabytes = (sizeA * sizeB * 8.0) / 1024.0 / 1024.0; //762 mb
double[][] randomNumbers = new double[sizeA][];
for (int i = 0; i < randomNumbers.Length; i++)
{
    randomNumbers[i] = new double[sizeB];
}

Then, to get a particular index you would use randomNumbers[i / sizeB][i % sizeB].

Another option if you always access the values in order might be to use the overloaded constructor to specify the seed. This way you would get a semi random number (like the DateTime.Now.Ticks) store it in a variable, then when ever you start going through the list you would create a new Random instance using the original seed:

private static int randSeed = (int)DateTime.Now.Ticks;  //Must stay the same unless you want to get different random numbers.
private static Random GetNewRandomIterator()
{
    return new Random(randSeed);
}

It is important to note that while the blog linked in Fredrik Mörk's answer indicates that the issue is usually due to a lack of address space it does not list a number of other issues, like the 2GB CLR object size limitation (mentioned in a comment from ShuggyCoUk on the same blog), glosses over memory fragmentation, and fails to mention the impact of page file size (and how it can be addressed with the use of the CreateFileMapping function).

The 2GB limitation means that randomNumbers must be less than 2GB. Since arrays are classes and have some overhead them selves this means an array of double will need to be smaller then 2^31. I am not sure how much smaller then 2^31 the Length would have to be, but Overhead of a .NET array? indicates 12 - 16 bytes.

Memory fragmentation is very similar to HDD fragmentation. You might have 2GB of address space, but as you create and destroy objects there will be gaps between the values. If these gaps are too small for your large object, and additional space can not be requested, then you will get the System.OutOfMemoryException. For example, if you create 2 million, 1024 byte objects, then you are using 1.9GB. If you delete every object where the address is not a multiple of 3 then you will be using .6GB of memory, but it will be spread out across the address space with 2024 byte open blocks in between. If you need to create an object which was .2GB you would not be able to do it because there is not a block large enough to fit it in and additional space cannot be obtained (assuming a 32 bit environment). Possible solutions to this issue are things like using smaller objects, reducing the amount of data you store in memory, or using a memory management algorithm to limit/prevent memory fragmentation. It should be noted that unless you are developing a large program which uses a large amount of memory this will not be an issue. Also, this issue can arise on 64 bit systems as windows is limited mostly by the page file size and the amount of RAM on the system.

Since most programs request working memory from the OS and do not request a file mapping, they will be limited by the system's RAM and page file size. As noted in the comment by Néstor Sánchez (Néstor Sánchez) on the blog, with managed code like C# you are stuck to the RAM/page file limitation and the address space of the operating system.

That was way longer then expected. Hopefully it helps someone. I posted it because I ran into the System.OutOfMemoryException running a x64 program on a system with 24GB of RAM even though my array was only holding 2GB of stuff.

If you are only interested in the packages installed globally without the full TREE then:

npm -g ls --depth=0

or locally (omit -g) :

npm ls --depth=0

For me only way to delete project was switch language to English (UK) - from Polish and then button "DELETE" worked. If anyone have problem with not working or missing options in Google Cloud Platform I suggest switching to english after that everything works like charm...

I found that when the widget is part of a function and the grid_remove is part of another function it does not remove the label. In this example...

def somefunction(self):
    Label(self, text=" ").grid(row = 0, column = 0)
    self.text_ent = Entry(self)
    self.text_ent.grid(row = 1, column = 0)
def someotherfunction(self):
    somefunction.text_ent.grid_remove()

...there is no valid way of removing the Label.

The only solution I could find is to give the label a name and make it global:

def somefunction(self):
    global label
    label = Label(self, text=" ")
    label.grid(row = 0, column = 0)
    self.text_ent = Entry(self)
    self.text_ent.grid(row = 1, column = 0)
def someotherfunction(self):
    global label
    somefunction.text_ent.grid_remove()
    label.grid_remove()

When I ran into this problem there was a class involved, one function being in the class and one not, so I'm not sure the global label lines are really needed in the above.

I came across this thread while working on my understanding of Cython. My extension to the original question might be of use to others working at the C / Cython interface. So this is the extension of the original question: how do I return a string from a C function, making it available to Cython & thus to Python?

For those not familiar with it, Cython allows you to statically type Python code that you need to speed up. So the process is, enjoy writing Python :), find its a bit slow somewhere, profile it, calve off a function or two and cythonize them. Wow. Close to C speed (it compiles to C) Fixed. Yay. The other use is importing C functions or libraries into Python as done here.

This will print a string and return the same or another string to Python. There are 3 files, the c file c_hello.c, the cython file sayhello.pyx, and the cython setup file sayhello.pyx. When they are compiled using python setup.py build_ext --inplace they generate a shared library file that can be imported into python or ipython and the function sayhello.hello run.

c_hello.c

#include <stdio.h>

char *c_hello() {
  char *mystr = "Hello World!\n";
  return mystr;
  // return "this string";  // alterative
}

sayhello.pyx

cdef extern from "c_hello.c":
    cdef char* c_hello()

def hello():
    return c_hello()

setup.py

from setuptools import setup
from setuptools.extension import Extension
from Cython.Distutils import build_ext
from Cython.Build import cythonize


ext_modules = cythonize([Extension("sayhello", ["sayhello.pyx"])])


setup(
name = 'Hello world app',
cmdclass = {'build_ext': build_ext},
ext_modules = ext_modules
)

Try the following instead:

<html>
 <head>
  <title>Table row styling</title>
  <style type="text/css">
    .bb td, .bb th {
     border-bottom: 1px solid black !important;
    }
  </style>
 </head>
 <body>
  <table>
    <tr class="bb">
      <td>This</td>
      <td>should</td>
      <td>work</td>
    </tr>
  </table>
 </body>
</html>

In Linux environment, after installing docker and docker-compose reboot is required for work docker better.

$ reboot

OR restart the docker

$ sudo systemctl restart docker

I first encountered this issue months ago (also on the click() command), and it has been an issue for me ever since. It seems to be some sort of problem with the .NET Selenium bindings. This blog post by the guy that works on the IE driver is helpful in explaining what's happening:

http://jimevansmusic.blogspot.com/2012/11/net-bindings-whaddaymean-no-response.html

Unfortunately, there doesn't seem to be a real solution to this problem. Whenever this issue has been raised to the Selenium developers (see here), this is a typical response:

We need a reproducible scenario, that must include a sample page or a link to a public site's page where the issue can be reproduced.

If you are able to submit a consistently reproducible test case, that could be very helpful in putting this bug to rest for good.

That said, perhaps you can try this workaround in the meantime. If the HTML button that you are trying to click() has an onclick attribute which contains Javascript, consider using a JavascriptExecutor to execute that code directly, rather than calling the click() command. I found that executing the onclick Javascript directly allows some of my tests to pass.

Position the outer div however you want, then position the inner divs using absolute. They'll all stack up.

.inner {_x000D_
  position: absolute;_x000D_
}

<div class="outer">_x000D_
   <div class="inner">1</div>_x000D_
   <div class="inner">2</div>_x000D_
   <div class="inner">3</div>_x000D_
   <div class="inner">4</div>_x000D_
</div>

This works too:

var exeBlk = {
    () -> Void in
}
exeBlk = {
    //do something
}
//instead of nil:
exeBlk = {}

Create a POJO Java Class for the objects in the list like so:

class NameUrlClass{
       private String name;
       private String url;
       //Constructor
       public NameUrlClass(String name,String url){
              this.name = name;
              this.url = url; 
        }
}

Now simply create a List of NameUrlClass and initialize it to an ArrayList like so:

List<NameUrlClass> obj = new ArrayList<NameUrlClass>;

You can use store the JSON array in this object

obj = JSONArray;//[{"name":"name1","url":"url1"}{"name":"name2","url":"url2"},...]

To check for null values you can use is_null() as is demonstrated below.

if (is_null($value)) {
   $value = "MY TEXT"; //define to suit
}

Yes, the moment jQuery sees the URL belongs to a different domain, it assumes that call as a cross domain call, thus crossdomain:true is not required here.

Also, important to note that you cannot make a synchronous call with $.ajax if your URL belongs to a different domain (cross domain) or you are using JSONP. Only async calls are allowed.

Note: you can call the service synchronously if you specify the async:false with your request.

There are a few problems here.

1: onBlur expects a callback, and you are calling renderPasswordConfirmError and using the return value, which is null.

2: you need a place to render the error.

3: you need a flag to track "and I validating", which you would set to true on blur. You can set this to false on focus if you want, depending on your desired behavior.

handleBlur: function () {
  this.setState({validating: true});
},
render: function () {
  return <div>
    ...
    <input
        type="password"
        placeholder="Password (confirm)"
        valueLink={this.linkState('password2')}
        onBlur={this.handleBlur}
     />
    ...
    {this.renderPasswordConfirmError()}
  </div>
},
renderPasswordConfirmError: function() {
  if (this.state.validating && this.state.password !== this.state.password2) {
    return (
      <div>
        <label className="error">Please enter the same password again.</label>
      </div>
    );
  }  
  return null;
},

I am not sure if this is the correct solution but I have achieved this by redefining .marquee class just after animation CSS.

Check below:

<style>
#marquee-wrapper{
    width:700px;
    display:block;
    border:1px solid red;
}

div.marquee{
width:100px;
height:100px;
background:red;
position:relative;
animation:myfirst 5s;
-moz-animation:myfirst 5s; /* Firefox */
}

@-moz-keyframes myfirst /* Firefox */{
0%   {background:red; left:0px; top:0px;}
100% {background:red; left:100%; top:0px}
}
div.marquee{ 
left:700px; top:0px
}
</style>

<!-- HTMl COde -->

<p><b>Note:</b> This example does not work in Internet Explorer and Opera.</p>
<div id="marquee-wrapper">
<div class="marquee"></div>

For a simple List structure the most efficient way seems to be using the Predicate RemoveAll implementation.

Eg.

 workSpace.RoleAssignments.RemoveAll(x =>x.Member.Name == shortName);

The reasons are:

1. The Predicate/Linq RemoveAll method is implemented in List and has access to the internal array storing the actual data. It will shift the data and resize the internal array.
2. The RemoveAt method implementation is quite slow, and will copy the entire underlying array of data into a new array. This means reverse iteration is useless for List

If you are stuck implementing this in a the pre c# 3.0 era. You have 2 options.

• The easily maintainable option. Copy all the matching items into a new list and and swap the underlying list.

Eg.

List<int> list2 = new List<int>() ; 
foreach (int i in GetList())
{
    if (!(i % 2 == 0))
    {
        list2.Add(i);
    }
}
list2 = list2;

Or

• The tricky slightly faster option, which involves shifting all the data in the list down when it does not match and then resizing the array.

If you are removing stuff really frequently from a list, perhaps another structure like a HashTable (.net 1.1) or a Dictionary (.net 2.0) or a HashSet (.net 3.5) are better suited for this purpose.

The following link explains filters in Angular extremely well. It shows how it is possible to define custom sort logic within an ng-repeat. http://toddmotto.com/everything-about-custom-filters-in-angular-js

For sorting object with properties, this is the code I have used: (Note that this sort is the standard JavaScript sort method and not specific to angular) Column Name is the name of the property on which sorting is to be performed.

self.myArray.sort(function(itemA, itemB) {
    if (self.sortOrder === "ASC") {
        return itemA[columnName] > itemB[columnName];
    } else {
        return itemA[columnName] < itemB[columnName];
    }
});

You can commit some updated files, like this:

git commit file1 file2 file5 -m "commit message"

Yes, they do completely different things. pass simply does nothing, while continue goes on with the next loop iteration. In your example, the difference would become apparent if you added another statement after the if: After executing pass, this further statement would be executed. After continue, it wouldn't.

>>> a = [0, 1, 2]
>>> for element in a:
...     if not element:
...         pass
...     print element
... 
0
1
2
>>> for element in a:
...     if not element:
...         continue
...     print element
... 
1
2

The trick is to represent the algorithms state, which is an integer multi-set, as a compressed stream of "increment counter"="+" and "output counter"="!" characters. For example, the set {0,3,3,4} would be represented as "!+++!!+!", followed by any number of "+" characters. To modify the multi-set you stream out the characters, keeping only a constant amount decompressed at a time, and make changes inplace before streaming them back in compressed form.

Details

We know there are exactly 10^6 numbers in the final set, so there are at most 10^6 "!" characters. We also know that our range has size 10^8, meaning there are at most 10^8 "+" characters. The number of ways we can arrange 10^6 "!"s amongst 10^8 "+"s is (10^8 + 10^6) choose 10^6, and so specifying some particular arrangement takes ~0.965 MiB` of data. That'll be a tight fit.

We can treat each character as independent without exceeding our quota. There are exactly 100 times more "+" characters than "!" characters, which simplifies to 100:1 odds of each character being a "+" if we forget that they are dependent. Odds of 100:101 corresponds to ~0.08 bits per character, for an almost identical total of ~0.965 MiB (ignoring the dependency has a cost of only ~12 bits in this case!).

The simplest technique for storing independent characters with known prior probability is Huffman coding. Note that we need an impractically large tree (A huffman tree for blocks of 10 characters has an average cost per block of about 2.4 bits, for a total of ~2.9 Mib. A huffman tree for blocks of 20 characters has an average cost per block of about 3 bits, which is a total of ~1.8 MiB. We're probably going to need a block of size on the order of a hundred, implying more nodes in our tree than all the computer equipment that has ever existed can store.). However, ROM is technically "free" according to the problem and practical solutions that take advantage of the regularity in the tree will look essentially the same.

Pseudo-code

• Have a sufficiently large huffman tree (or similar block-by-block compression data) stored in ROM
• Start with a compressed string of 10^8 "+" characters.
• To insert the number N, stream out the compressed string until N "+" characters have gone past then insert a "!". Stream the recompressed string back over the previous one as you go, keeping a constant amount of buffered blocks to avoid over/under-runs.
• Repeat one million times: [input, stream decompress>insert>compress], then decompress to output

There are many way to convert an integer to a string:

1)

Integer.toString(10);

2)

 String hundred = String.valueOf(100); // You can pass an int constant
 int ten = 10;
 String ten = String.valueOf(ten)

3)

String thousand = "" + 1000; // String concatenation

4)

String million = String.format("%d", 1000000)

First, you don't declare the type in Ruby, so you don't need the first string.

To replace a word in string, you do: sentence.gsub(/match/, "replacement").

In modern browsers (IE8, Firefox, Chrome, Opera, Safari) you can use querySelector():

function test(el){
  el.querySelector("#child").style.display = "none";
}

For older browsers (<=IE7), you would have to use some sort of library, such as Sizzle or a framework, such as jQuery, to work with selectors.

As mentioned, IDs are supposed to be unique within a document, so it's easiest to just use document.getElementById("child").

@IBInspectable is working for me on iOS 9 , Swift 2.0

extension UIView {

@IBInspectable var borderWidth: CGFloat {
get {
        return layer.borderWidth
    }
    set(newValue) {
        layer.borderWidth = newValue
    }
}

@IBInspectable var cornerRadius: CGFloat {
    get {
        return layer.cornerRadius
    }
    set(newValue) {
        layer.cornerRadius = newValue
    }
}

@IBInspectable var borderColor: UIColor? {
    get {
        if let color = layer.borderColor {
            return UIColor(CGColor: color)
        }
        return nil
    }
    set(newValue) {
        layer.borderColor = newValue?.CGColor
    }
}

This works in MariaDB:

SELECT Req_ID, (R1+R2+R3+R4+R5)/5 AS Average
FROM Request
GROUP BY Req_ID;

In Angular 8 you can simply use "selectionChange" like this:

 <mat-select  [(value)]="selectedData" (selectionChange)="onChange()" >
  <mat-option *ngFor="let i of data" [value]="i.ItemID">
  {{i.ItemName}}
  </mat-option>
 </mat-select>

Use data URL scheme: https://en.wikipedia.org/wiki/Data_URI_scheme

In this case you use that string directly in html : <img src="data:image/png;base64,iVBOR....">

It's tangential, but here's a tip for those using Rackt's React Router library with (HTML5) browser history who want to host on S3.

Suppose a user visits /foo/bear at your S3-hosted static web site. Given David's earlier suggestion, redirect rules will send them to /#/foo/bear. If your application's built using browser history, this won't do much good. However your application is loaded at this point and it can now manipulate history.

Including Rackt history in our project (see also Using Custom Histories from the React Router project), you can add a listener that's aware of hash history paths and replace the path as appropriate, as illustrated in this example:

import ReactDOM from 'react-dom';

/* Application-specific details. */
const route = {};

import { Router, useRouterHistory } from 'react-router';
import { createHistory } from 'history';

const history = useRouterHistory(createHistory)();

history.listen(function (location) {
  const path = (/#(\/.*)$/.exec(location.hash) || [])[1];
  if (path) history.replace(path);
});

ReactDOM.render(
  <Router history={history} routes={route}/>,
  document.body.appendChild(document.createElement('div'))
);

To recap:

1. David's S3 redirect rule will direct /foo/bear to /#/foo/bear.
2. Your application will load.
3. The history listener will detect the #/foo/bear history notation.
4. And replace history with the correct path.

Link tags will work as expected, as will all other browser history functions. The only downside I've noticed is the interstitial redirect that occurs on initial request.

This was inspired by a solution for AngularJS, and I suspect could be easily adapted to any application.

You can't do it in a single query, but you could do it within a transaction. Do the initial MAX() select and lock the table, then do the insert. The transaction ensures that nothing will interrupt the two queries, and the lock ensures that nothing else can try doing the same thing elsewhere at the same time.

It is not very logical to convert TimeSpan to DateTime. Try to understand what leppie said above. TimeSpan is a duration say 6 Days 5 Hours 40 minutes. It is not a Date. If I say 6 Days; Can you deduce a Date from it? The answer is NO unless you have a REFERENCE Date.

So if you want to convert TimeSpan to DateTime you need a reference date. 6 Days & 5 Hours from when? So you can write something like this:

 DateTime dt = new DateTime(2012, 01, 01);
 TimeSpan ts = new TimeSpan(1, 0, 0, 0, 0);
 dt = dt + ts;

Change the File Permission using chmod command

sudo chmod 700 keyfile.pem

I am posting the following because it is a very simple and clear way to mimic (at least to some extent) the behavior of a two-dimensional array in Bash. It uses a here-file (see the Bash manual) and read (a Bash builtin command):

## Store the "two-dimensional data" in a file ($$ is just the process ID of the shell, to make sure the filename is unique)
cat > physicists.$$ <<EOF
Wolfgang Pauli 1900
Werner Heisenberg 1901
Albert Einstein 1879
Niels Bohr 1885
EOF
nbPhysicists=$(wc -l physicists.$$ | cut -sf 1 -d ' ')     # Number of lines of the here-file specifying the physicists.

## Extract the needed data
declare -a person     # Create an indexed array (necessary for the read command).                                                                                 
while read -ra person; do
    firstName=${person[0]}
    familyName=${person[1]}
    birthYear=${person[2]}
    echo "Physicist ${firstName} ${familyName} was born in ${birthYear}"
    # Do whatever you need with data
done < physicists.$$

## Remove the temporary file
rm physicists.$$

Output: Physicist Wolfgang Pauli was born in 1900 Physicist Werner Heisenberg was born in 1901 Physicist Albert Einstein was born in 1879 Physicist Niels Bohr was born in 1885

The way it works:

• The lines in the temporary file created play the role of one-dimensional vectors, where the blank spaces (or whatever separation character you choose; see the description of the read command in the Bash manual) separate the elements of these vectors.
• Then, using the read command with its -a option, we loop over each line of the file (until we reach end of file). For each line, we can assign the desired fields (= words) to an array, which we declared just before the loop. The -r option to the read command prevents backslashes from acting as escape characters, in case we typed backslashes in the here-document physicists.$$.

In conclusion a file is created as a 2D-array, and its elements are extracted using a loop over each line, and using the ability of the read command to assign words to the elements of an (indexed) array.

Slight improvement:

In the above code, the file physicists.$$ is given as input to the while loop, so that it is in fact passed to the read command. However, I found that this causes problems when I have another command asking for input inside the while loop. For example, the select command waits for standard input, and if placed inside the while loop, it will take input from physicists.$$, instead of prompting in the command-line for user input. To correct this, I use the -u option of read, which allows to read from a file descriptor. We only have to create a file descriptor (with the exec command) corresponding to physicists.$$ and to give it to the -u option of read, as in the following code:

## Store the "two-dimensional data" in a file ($$ is just the process ID of the shell, to make sure the filename is unique)
cat > physicists.$$ <<EOF
Wolfgang Pauli 1900
Werner Heisenberg 1901
Albert Einstein 1879
Niels Bohr 1885
EOF
nbPhysicists=$(wc -l physicists.$$ | cut -sf 1 -d ' ')     # Number of lines of the here-file specifying the physicists.
exec {id_file}<./physicists.$$     # Create a file descriptor stored in 'id_file'.

## Extract the needed data
declare -a person     # Create an indexed array (necessary for the read command).                                                                                 
while read -ra person -u "${id_file}"; do
firstName=${person[0]}
familyName=${person[1]}
birthYear=${person[2]}
echo "Physicist ${firstName} ${familyName} was born in ${birthYear}"
# Do whatever you need with data
done

## Close the file descriptor
exec {id_file}<&-
## Remove the temporary file
rm physicists.$$

Notice that the file descriptor is closed at the end.

You need to add the log destination specifiers before the filename to run. So

forever -e /path/error.txt -o /path/output.txt start index.js

Found following solution working for my similar problem:

private ExtendedHashMap mData = new ExtendedHashMap();
private  String[] mKeys;

public void setNewData(ExtendedHashMap data) {
    mData.putAll(data);
    mKeys = data.keySet().toArray(new String[data.size()]);
    notifyDataSetChanged();
}

Using the clear-command

mData.clear()

is not nessescary

Your question is pretty hard to decode, but I'll try taking a stab at it.

You say:

I want to create a json object having two fields uniqueIDofSelect and optionValue in javascript.

And then you say:

I need output like

[{"selectID":2,"optionValue":"2"},
{"selectID":4,"optionvalue":"1"}]

Well, this example output doesn't have the field named uniqueIDofSelect, it only has optionValue.

Anyway, you are asking for array of objects...

Then in the comment to michaels answer you say:

It creates json object array. but I need only one json object.

So you don't want an array of objects?

What do you want then?

Please make up your mind.

Step 1: Install XML Tools plugin
Step 2: Format ....completed

I followed the advice of Simon Gibbs in this answer and found it worked out fine - if you're in a hurry, the "Web Page Editor (optional)" package from the Eclipse update site does the trick.

For the Eclipse-challenged (me) Help > Install New Software > Work with > Expand Web, XML, and Java EE Development > Select "Web Page Editor (optional)" and "next-through" to completion.

As for me, using VSCode and Angular 5, only had to add "node" to types in tsconfig.app.json. Save, and restart the server.

{_x000D_
    "compilerOptions": {_x000D_
    .._x000D_
    "types": [_x000D_
      "node"_x000D_
    ]_x000D_
  }_x000D_
  .._x000D_
}

One curious thing, is that this problem "cannot find require (", does not happen when excuting with ts-node

In addition to nexe, browserify can be used to bundle up all your dependencies as a single .js file. This does not bundle the actual node executable, just handles the javascript side. It too does not handle native modules. The command line options for pure node compilation would be browserify --output bundle.js --bare --dg false input.js.

You can get the ID, or any other attribute, using jQuery's attrib function.

$('ul.art-vmenu li').attrib('id');

To get the menu text, which is in the t span, you can do this:

$('ul.art-vmenu li').children('span.t').html();

To change the HTML is just as easy:

$('ul.art-vmenu li').children('span.t').html("I'm different");

Of course, if you wanted to get all the span.t's in the first place, it would be simpler to do:

$('ul.art-vemnu li span.t').html();

But I'm assuming you've already got the li's, and want to use child() to find something within that element.

USE AT YOUR OWN RISK. INFORMATION PROVIDED 'AS IS'. NOT TESTED EXTENSIVELY.

Right-click Windows icon (usually bottom left) > click "Windows PowerShell (Admin)" > use this command (with due care, you can easily delete all your files if you're not careful):

rd -r -include *.* -force somedir

Where somedir is the non-empty directory you want to remove.

Note that with external attached disks, or disks with issues, Windows sometimes behaves odd - it does not error in the delete (or any copy attempt), yet the directory is not deleted (or not copied) as instructed. (I found that in this case, at least for me, the command given by @n_y in his answer will produce errors like 'get-childitem : The file or directory is corrupted and unreadable.' as a result in PowerShell)

you can use regex as the delimiter:

pd.read_csv("whitespace.csv", header=None, delimiter=r"\s+")

The simple way to do your test is :

function (data) {
    if (data) { // check if null, undefined, empty ...
        // some code here
    }
}

If you know on what port it would be running(by default it would be 6379), you can use below command to get the pid of the process using that port and then can execute kill command for the same pid.

sudo lsof -i : <port> | awk '{print $2}'

the above command will give you pid.

kill <pid>;

This would shutdown your server.

multi comment in vb.net

VB.NET doesn't support for multi line comment.

The only way to do multi-line comments in VB.NET is to do a lot of single line comments(').

Or just highlight the whole code and just use (Ctrl+E,C), (Ctrl+E,U) to comment or uncomment.

Only in c# /* */

Or in ASP.NET html source using <!-- -->.

You have at least two issues in your code:

• ng-change="getScoreData(Score)

  Angular doesn't see getScoreData method that refers to defined service

• getScoreData: function (Score, callback)

  We don't need to use callback since GET returns promise. Use then instead.

Here is a working example (I used random address only for simulation):

HTML

<select ng-model="score"
        ng-change="getScoreData(score)" 
        ng-options="score as score.name for score in  scores"></select>
    <pre>{{ScoreData|json}}</pre> 

JS

var fessmodule = angular.module('myModule', ['ngResource']);

fessmodule.controller('fessCntrl', function($scope, ScoreDataService) {

    $scope.scores = [{
        name: 'Bukit Batok Street 1',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, 153 Bukit Batok Street 1&sensor=true'
    }, {
        name: 'London 8',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, London 8&sensor=true'
    }];

    $scope.getScoreData = function(score) {
        ScoreDataService.getScoreData(score).then(function(result) {
            $scope.ScoreData = result;
        }, function(result) {
            alert("Error: No data returned");
        });
    };

});

fessmodule.$inject = ['$scope', 'ScoreDataService'];

fessmodule.factory('ScoreDataService', ['$http', '$q', function($http) {

    var factory = {
        getScoreData: function(score) {
            console.log(score);
            var data = $http({
                method: 'GET',
                url: score.URL
            });


            return data;
        }
    }
    return factory;
}]);

I was trying to use CURL to do some https API calls with php and ran into this problem. I noticed a recommendation on the php site which got me up and running: http://php.net/manual/en/function.curl-setopt.php#110457

Please everyone, stop setting CURLOPT_SSL_VERIFYPEER to false or 0. If your PHP installation doesn't have an up-to-date CA root certificate bundle, download the one at the curl website and save it on your server:

http://curl.haxx.se/docs/caextract.html

Then set a path to it in your php.ini file, e.g. on Windows:

curl.cainfo=c:\php\cacert.pem

Turning off CURLOPT_SSL_VERIFYPEER allows man in the middle (MITM) attacks, which you don't want!

Cast the dtype of the col to str and you can perform vectorised slicing calling str:

In [29]:
df['new_col'] = df['First'].astype(str).str[0]
df

Out[29]:
   First  Second new_col
0    123     234       1
1     22    4353       2
2     32     355       3
3    453     453       4
4     45     345       4
5    453     453       4
6     56      56       5

if you need to you can cast the dtype back again calling astype(int) on the column

In these days of Git everywhere, you may forget CMake and use git clean -d -f -x, that will remove all files not under source control.

there are npm packages that bind to the system gettimeofday() function, which returns a microsecond precision timestamp on Linux. Search for npm gettimeofday. Calling C is faster than process.hrtime()

This question has been answered over and over again :-) but why not.

First using tput is more portable in modern environments than manually injecting ASCII codes through echo -E

Here's a quick bash function:

 say() {
     echo "$@" | sed \
             -e "s/\(\(@\(red\|green\|yellow\|blue\|magenta\|cyan\|white\|reset\|b\|u\)\)\+\)[[]\{2\}\(.*\)[]]\{2\}/\1\4@reset/g" \
             -e "s/@red/$(tput setaf 1)/g" \
             -e "s/@green/$(tput setaf 2)/g" \
             -e "s/@yellow/$(tput setaf 3)/g" \
             -e "s/@blue/$(tput setaf 4)/g" \
             -e "s/@magenta/$(tput setaf 5)/g" \
             -e "s/@cyan/$(tput setaf 6)/g" \
             -e "s/@white/$(tput setaf 7)/g" \
             -e "s/@reset/$(tput sgr0)/g" \
             -e "s/@b/$(tput bold)/g" \
             -e "s/@u/$(tput sgr 0 1)/g"
  }

Now you can use:

 say @b@green[[Success]] 

to get:

Notes on portability of tput

First time tput(1) source code was uploaded in September 1986

tput(1) has been available in X/Open curses semantics in 1990s (1997 standard has the semantics mentioned below).

So, it's (quite) ubiquitous.

Note: This answer does not explicitly answer the asked question. the other answers do it. Since the question is specific to a scenario and the raised exception is general, This answer points to the general case.

Hash values are just integers which are used to compare dictionary keys during a dictionary lookup quickly.

Internally, hash() method calls __hash__() method of an object which are set by default for any object.

Converting a nested list to a set

>>> a = [1,2,3,4,[5,6,7],8,9]
>>> set(a)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

This happens because of the list inside a list which is a list which cannot be hashed. Which can be solved by converting the internal nested lists to a tuple,

>>> set([1, 2, 3, 4, (5, 6, 7), 8, 9])
set([1, 2, 3, 4, 8, 9, (5, 6, 7)])

Explicitly hashing a nested list

>>> hash([1, 2, 3, [4, 5,], 6, 7])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'


>>> hash(tuple([1, 2, 3, [4, 5,], 6, 7]))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

>>> hash(tuple([1, 2, 3, tuple([4, 5,]), 6, 7]))
-7943504827826258506

The solution to avoid this error is to restructure the list to have nested tuples instead of lists.

Why not a/b/(c|d|e)? I just tried with Saxon XML library (wrapped up nicely with some Clojure goodness), and it seems to work. abc.xml is the doc described by OP.

(require '[saxon :as xml])
(def abc-doc (xml/compile-xml (slurp "abc.xml")))
(xml/query "a/b/(c|d|e)" abc-doc)
=> (#<XdmNode <c>C1</c>>
    #<XdmNode <d>D1</d>>
    #<XdmNode <e>E1</e>>
    #<XdmNode <c>C2</c>>
    #<XdmNode <d>D2</d>>
    #<XdmNode <e>E1</e>>)

set -o xtrace

or

bash -x myscript.sh

This works with standard /bin/sh as well IIRC (it might be a POSIX thing then)

And remember, there is bashdb (bash Shell Debugger, release 4.0-0.4)

To revert to normal, exit the subshell or

set +o xtrace

You'll have to use the ChannelFactory class.

Here's an example:

var myBinding = new BasicHttpBinding();
var myEndpoint = new EndpointAddress("http://localhost/myservice");
using (var myChannelFactory = new ChannelFactory<IMyService>(myBinding, myEndpoint))
{
    IMyService client = null;

    try
    {
        client = myChannelFactory.CreateChannel();
        client.MyServiceOperation();
        ((ICommunicationObject)client).Close();
        myChannelFactory.Close();
    }
    catch
    {
        (client as ICommunicationObject)?.Abort();
    }
}

In case you are using the annotation method for filter definition (as opposed to defining them in the web.xml), you can do so by just putting an array of mappings in the @WebFilter annotation:

/**
 * Filter implementation class LoginFilter
 */
@WebFilter(urlPatterns = { "/faces/Html/Employee","/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginFilter implements Filter {
    ...

And just as an FYI, this same thing works for servlets using the servlet annotation too:

/**
 * Servlet implementation class LoginServlet
 */
@WebServlet({"/faces/Html/Employee", "/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginServlet extends HttpServlet {
    ...

TL;DR: Check the path to your keystore.jks file.

In my case, here's what happened:

I moved the project folder of my entire app to another location on my PC. Much later, I wanted to generate a signed apk file. Unknown to me, the default location of the path to my keystore.jks had been reset to a wrong location and I had clicked okay. Since it could not find a keystore at the path I selected, I got that error.

The solution was to check whether the path to my keystore.jks file was correct.

In .Net 5.x, update your ConfigureServices method in startup.cs with the below code

public void ConfigureServices(IServiceCollection services)
{
    ----------------
    ----------------
    services.AddMvc().AddJsonOptions(options =>
    {
        options.JsonSerializerOptions.ReferenceHandler = ReferenceHandler.Preserve;
    });
    ------------------
}

By default, serialization (System.Text.Json.Serialization) does not support objects with cycles and does not preserve duplicate references. Use Preserve to enable unique object reference preservation on serialization and metadata consumption to read preserved references on deserialization. MSDN Link

string[] lines = File.ReadAllLines(txtProxyListPath.Text);

// No need for the list
// List<string> list_lines = new List<string>(lines); 

Parallel.ForEach(lines, line =>
{
    //My Stuff
});

This will cause the lines to be parsed in parallel, within the loop. If you want a more detailed, less "reference oriented" introduction to the Parallel class, I wrote a series on the TPL which includes a section on Parallel.ForEach.

For newer version of laravel:

composer create-project --prefer-dist laravel/laravel=5.5.* project_name

This function removes an element from an array from a specific position.

array.remove(position);

Array.prototype.remove = function (pos) {
    this.splice(pos, 1);
}

var arr = ["a", "b", "c", "d", "e"];
arr.remove(2); //remove c
console.log(arr);

As others have mentioned, comments are referenced with a # and are documented here. However, unlike some languages, the # must be at the beginning of the line. If they occur part way through the line, they are interpreted as an argument and may result in unexpected behavior.

# This is a comment

COPY test_dir target_dir # This is not a comment, it is an argument to COPY

RUN echo hello world # This is an argument to RUN but the shell may ignore it

It should also be noted that parser directives have recently been added to the Dockerfile which have the same syntax as a comment. They need to appear at the top of the file, before any other comments or commands. Originally, this directive was added for changing the escape character to support Windows:

# escape=`

FROM microsoft/nanoserver
COPY testfile.txt c:\
RUN dir c:\

The first line, while it appears to be a comment, is a parser directive to change the escape character to a backtick so that the COPY and RUN commands can use the backslash in the path. A parser directive is also used with BuildKit to change the frontend parser with a syntax line. See the experimental syntax for more details on how this is being used in practice.

With a multi-line command, the commented lines are ignored, but you need to comment out every line individually:

$ cat Dockerfile
FROM busybox:latest
RUN echo first command \
# && echo second command disabled \
 && echo third command

$ docker build .

The other queries are all going base on any ONE of the conditions qualifying and it will return a record... if you want to make sure the BOTH columns of table A are matched, you'll have to do something like...

select 
      tA.Col1,
      tA.Col2,
      tB.Val
   from
      TableA tA
         join TableB tB
            on  ( tA.Col1 = tB.Col1 OR tA.Col1 = tB.Col2 )
            AND ( tA.Col2 = tB.Col1 OR tA.Col2 = tB.Col2 )

The user agent string is a text that the browsers themselves send to the webserver to identify themselves, so that websites can send different content based on the browser or based on browser compatibility.

Mozilla is a browser rendering engine (the one at the core of Firefox) and the fact that Chrome and IE contain the string Mozilla/4 or /5 identifies them as being compatible with that rendering engine.

Aside from limiting the columns selected to reduce bandwidth and memory:

DataTable t;
t.Columns.Remove("columnName");
t.Columns.RemoveAt(columnIndex);

Also as a minor enhancement.

The main reason for the try/catch block is that e1 could be null for the initial movement. in addition to the try/catch, include a test for null and return. similar to the following

if (e1 == null || e2 == null) return false;
try {
...
} catch (Exception e) {}
return false;

We had the same problem, such a nightmare.

1. Make sure your App IDs and Secret Keys are correct. If you are using separate development, staging and production apps for testing, the App IDs and Secret Keys are all different for each app. This is often the problem.

2. Make sure you have the callback URL set properly in your app config file (see below). And then add this as same URL under "Facebook Login" settings where it says "Valid OAuth redirect URIs". It should look like this (depending on your environment):

http://localhost/auth/facebook/callback http://staging.example.com/auth/facebook/callback http://example.com/auth/facebook/callback

3. Make sure your app domain is set to the correct domain for each environment, including both "www" and "no-www". Facebook also requires these domains to match the URL of your website or app platform. You will have to select "Add Platform" to add this.

I found your question because I was also fighting with NSAttributedString. For me, the beginEditing and endEditing methods did the trick, like stated in Changing an Attributed String. Apart from that, the lineSpacing is set with setLineSpacing on the paragraphStyle.

So you might want to try changing your code to:

NSString *string = @" Hello \n world";
attrString = [[NSMutableAttributedString alloc] initWithString:string];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle defaultParagraphStyle] mutableCopy];

[paragraphStyle setLineSpacing:20]  // Or whatever (positive) value you like...    
[attrSting beginEditing];

[attrString addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:20] range:NSMakeRange(0, string.length)];
[attrString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, string.length)];

[attrString endEditing];

mainTextView.attributedText = attrString;

Didn't test this exact code though, btw, but mine looks nearly the same.

EDIT:

Meanwhile, I've tested it, and, correct me if I'm wrong, the - beginEditing and - endEditing calls seem to be of quite an importance.

The reason you're getting so many different answers is because you've not explained what you want to do exactly. All the answers you get with code will be programmatically correct, but it's all down to what you want to achieve

Do same as you did in file1.c In file2.c:

#include <stdio.h> 

extern int i;  /*This declare that i is an int variable which is defined in some other file*/

int main(void)
{
/* your code*/

If you use int i; in file2.c under main() then i will be treated as local auto variable not the same as defined in file1.c

This does the same, enhanced with CONTAINS:

Function SingleCellExtract(LookupValue As String, LookupRange As Range, ColumnNumber As Integer, Char As String)
Dim I As Long
Dim xRet As String
For I = 1 To LookupRange.Columns(1).Cells.Count
     If InStr(1, LookupRange.Cells(I, 1), LookupValue) > 0 Then
        If xRet = "" Then
            xRet = LookupRange.Cells(I, ColumnNumber) & Char
        Else
            xRet = xRet & "" & LookupRange.Cells(I, ColumnNumber) & Char
        End If
    End If
Next
SingleCellExtract = Left(xRet, Len(xRet) - 1)
End Function

jdk max version is 1.8.0_144

then run monitor

The explanation from Scott Meyers in Effective C++ might help understand when to use them:

Public inheritance should model "is-a relationship," whereas private inheritance should be used for "is-implemented-in-terms-of" - so you don't have to adhere to the interface of the superclass, you're just reusing the implementation.

Kotlin solution using context extension

fun Context.applyNewLocale(locale: Locale): Context {
    val config = this.resources.configuration
    val sysLocale = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        config.locales.get(0)
    } else {
        //Legacy
        config.locale
    }
    if (sysLocale.language != locale.language) {
        Locale.setDefault(locale)
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            config.setLocale(locale)
        } else {
            //Legacy
            config.locale = locale
        }
        resources.updateConfiguration(config, resources.displayMetrics)
    }
    return this
}

Usage

override fun attachBaseContext(newBase: Context?) {
    super.attachBaseContext(newBase?.applyNewLocale(Locale("es", "MX")))
}
