use this URL : "https://twitter.com/(userName)/profile_image?size=original"

If you are using TWitter SDK you can get the user name when logged in, with TWTRAPIClient, using TWTRAuthSession.

This is the code snipe for iOS:

if let twitterId = session.userID{
   let twitterClient = TWTRAPIClient(userID: twitterId)
   twitterClient.loadUser(withID: twitterId) {(user, error) in
       if let userName = user?.screenName{
          let url = "https://twitter.com/\(userName)/profile_image?size=original")
       }
   }
}

The codeigniter framework contains a helper for this, called the "text helper". Here's some documentation from codeigniter's user guide that applies: http://codeigniter.com/user_guide/helpers/text_helper.html (just read the word_limiter and character_limiter sections). Here's two functions from it relevant to your question:

if ( ! function_exists('word_limiter'))
{
    function word_limiter($str, $limit = 100, $end_char = '…')
    {
        if (trim($str) == '')
        {
            return $str;
        }

        preg_match('/^\s*+(?:\S++\s*+){1,'.(int) $limit.'}/', $str, $matches);

        if (strlen($str) == strlen($matches[0]))
        {
            $end_char = '';
        }

        return rtrim($matches[0]).$end_char;
    }
}

And

if ( ! function_exists('character_limiter'))
{
    function character_limiter($str, $n = 500, $end_char = '…')
    {
        if (strlen($str) < $n)
        {
            return $str;
        }

        $str = preg_replace("/\s+/", ' ', str_replace(array("\r\n", "\r", "\n"), ' ', $str));

        if (strlen($str) <= $n)
        {
            return $str;
        }

        $out = "";
        foreach (explode(' ', trim($str)) as $val)
        {
            $out .= $val.' ';

            if (strlen($out) >= $n)
            {
                $out = trim($out);
                return (strlen($out) == strlen($str)) ? $out : $out.$end_char;
            }       
        }
    }
}

Date.prototype.addDays = function(days) {

   var dat = new Date(this.valueOf())
   dat.setDate(dat.getDate() + days);
   return dat;
}

function getDates(startDate, stopDate) {

  var dateArray = new Array();
  var currentDate = startDate;
  while (currentDate <= stopDate) {
    dateArray.push(currentDate);
    currentDate = currentDate.addDays(1);
  }
  return dateArray;
}

var dateArray = getDates(new Date(), (new Date().addDays(7)));

for (i = 0; i < dateArray.length; i ++ ) {
  //  alert (dateArray[i]);

    date=('0'+dateArray[i].getDate()).slice(-2);
    month=('0' +(dateArray[i].getMonth()+1)).slice(-2);
    year=dateArray[i].getFullYear();
    alert(date+"-"+month+"-"+year );
}

Is the following acceptable:

$('#myTableRow').remove();

I had this problem, after installing jdk7 next to Java 6. The binaries were correctly updated using update-alternatives --config java to jdk7, but the $JAVA_HOME environment variable still pointed to the old directory of Java 6.

The first push should be a:

git push -u origin branchname

That would make sure:

• your local branch has a remote tracking branch of the same name referring an upstream branch in your remote repo 'origin',
• this is compliant with the default push policy 'simple'

Any future git push will, with that default policy, only push the current branch, and only if that branch has an upstream branch with the same name.
that avoid pushing all matching branches (previous default policy), where tons of test branches were pushed even though they aren't ready to be visible on the upstream repo.

The HTML parser simply doesn't interpret the inlined javascript like this.

You may do this :

<td><input type="checkbox" id="repriseCheckBox" name="repriseCheckBox"/></td>

<script>document.getElementById("repriseCheckBox").disabled=checkStat == 1 ? true : false;</script>

In the default Java API you have:

String.CASE_INSENSITIVE_ORDER

So you do not need to rewrite a comparator if you were to use strings with Sorted data structures.

String s = "some text here";
s.equalsIgnoreCase("Some text here");

Is what you want for pure equality checks in your own code.

Just to further informations about anything pertaining to equality of Strings in Java. The hashCode() function of the java.lang.String class "is case sensitive":

public int hashCode() {
    int h = hash;
    if (h == 0 && value.length > 0) {
        char val[] = value;

        for (int i = 0; i < value.length; i++) {
            h = 31 * h + val[i];
        }
        hash = h;
    }
    return h;
}

So if you want to use an Hashtable/HashMap with Strings as keys, and have keys like "SomeKey", "SOMEKEY" and "somekey" be seen as equal, then you will have to wrap your string in another class (you cannot extend String since it is a final class). For example :

private static class HashWrap {
    private final String value;
    private final int hash;

    public String get() {
        return value;
    }

    private HashWrap(String value) {
        this.value = value;
        String lc = value.toLowerCase();
        this.hash = lc.hashCode();
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o instanceof HashWrap) {
            HashWrap that = (HashWrap) o;
            return value.equalsIgnoreCase(that.value);
        } else {
            return false;
        }
    }

    @Override
    public int hashCode() {
        return this.hash;
    }
}

and then use it as such:

HashMap<HashWrap, Object> map = new HashMap<HashWrap, Object>();

I have tried your code and it works just fine. The file is being created without any problem, this is the code I used (it's your code, I just changed the datasource for testing):

    public ActionResult ExportToExcel()
    {
        var products = new System.Data.DataTable("teste");
        products.Columns.Add("col1", typeof(int));
        products.Columns.Add("col2", typeof(string));

        products.Rows.Add(1, "product 1");
        products.Rows.Add(2, "product 2");
        products.Rows.Add(3, "product 3");
        products.Rows.Add(4, "product 4");
        products.Rows.Add(5, "product 5");
        products.Rows.Add(6, "product 6");
        products.Rows.Add(7, "product 7");


        var grid = new GridView();
        grid.DataSource = products;
        grid.DataBind();

        Response.ClearContent();
        Response.Buffer = true;
        Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
        Response.ContentType = "application/ms-excel";

        Response.Charset = "";
        StringWriter sw = new StringWriter();
        HtmlTextWriter htw = new HtmlTextWriter(sw);

        grid.RenderControl(htw);

        Response.Output.Write(sw.ToString());
        Response.Flush();
        Response.End();

        return View("MyView");
    }

Since seangwright's solution (Edit 3) appears to be very useful, I also found it a pain to pack this feature into base component, and hint other project teammates to remember to call super() on ngOnDestroy to activate this feature.

This answer provide a way to set free from super call, and make "componentDestroyed$" a core of base component.

class BaseClass {
    protected componentDestroyed$: Subject<void> = new Subject<void>();
    constructor() {

        /// wrap the ngOnDestroy to be an Observable. and set free from calling super() on ngOnDestroy.
        let _$ = this.ngOnDestroy;
        this.ngOnDestroy = () => {
            this.componentDestroyed$.next();
            this.componentDestroyed$.complete();
            _$();
        }
    }

    /// placeholder of ngOnDestroy. no need to do super() call of extended class.
    ngOnDestroy() {}
}

And then you can use this feature freely for example:

@Component({
    selector: 'my-thing',
    templateUrl: './my-thing.component.html'
})
export class MyThingComponent extends BaseClass implements OnInit, OnDestroy {
    constructor(
        private myThingService: MyThingService,
    ) { super(); }

    ngOnInit() {
        this.myThingService.getThings()
            .takeUntil(this.componentDestroyed$)
            .subscribe(things => console.log(things));
    }

    /// optional. not a requirement to implement OnDestroy
    ngOnDestroy() {
        console.log('everything works as intended with or without super call');
    }

}

Yes you can usually see what SOAP version is supported based on the WSDL.

Take a look at Demo web service WSDL. It has a reference to the soap12 namespace indicating it supports SOAP 1.2. If that was absent then you'd probably be safe assuming the service only supported SOAP 1.1.

Rather than needing inline you could use Internal CSS

<a href="http://www.google.com" style="hover:text-decoration:none;">Google</a>

You could have:

<a href="http://www.google.com" id="gLink">Google</a>
<style>
  #gLink:hover {
     text-decoration: none;
  }
</style>

booleanExpression ? trueValue : falseValue;

Example:

string itemText = count > 1 ? "items" : "item";

The name property is marked as protected. This was added in TypeScript 1.3 and is now firmly established.

The makeSound method is marked as abstract, as is the class. You cannot directly instantiate an Animal now, because it is abstract. This is part of TypeScript 1.6, which is now officially live.

abstract class Animal {
    constructor(protected name: string) { }

    abstract makeSound(input : string) : string;

    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    constructor(name: string) { super(name); }

    makeSound(input : string) : string {
        return "sssss"+input;
    }

    move() {
        alert("Slithering...");
        super.move(5);
    }
}

The old way of mimicking an abstract method was to throw an error if anyone used it. You shouldn't need to do this any more once TypeScript 1.6 lands in your project:

class Animal {
    constructor(public name) { }
    makeSound(input : string) : string {
        throw new Error('This method is abstract');
    }
    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    constructor(name) { super(name); }
    makeSound(input : string) : string {
        return "sssss"+input;
    }
    move() {
        alert("Slithering...");
        super.move(5);
    }
}

I have discovered that NotePad++ now also creates a subfolder at the file location, called nppBackup. So if your file lived in a folder called c:/thisfolder have a look to see if there's a folder called c:/thisfolder/nppBackup.

Occasionally I couldn't find the backup in AppData\Roaming\Notepad++\backup, but I found it in nppBackup.

Just download MySQL workbench to log in. It will prompt you to change the password immediately and automatically.

Normally a wart to indicate the type is appended or prepended to the name. You can get away with macros is some instances, but it rather depends what you're trying to do. There's no polymorphism in C, only coercion.

Simple generic operations can be done with macros:

#define max(x,y) ((x)>(y)?(x):(y))

If your compiler supports typeof, more complicated operations can be put in the macro. You can then have the symbol foo(x) to support the same operation different types, but you can't vary the behaviour between different overloads. If you want actual functions rather than macros, you might be able to paste the type to the name and use a second pasting to access it (I haven't tried).

Another possibility is that the result is not awaited on the client side. This can happen if any one method on the call stack does not use the await keyword to wait for the call to be completed.

You can either

1. surround the TextView by a ScrollView; or
2. set the Movement method to ScrollingMovementMethod.getInstance();.

The correct SQL connection string for SQL with specify port is use comma between ip address and port number like following pattern: xxx.xxx.xxx.xxx,yyyy

You can also try /etc/redhat-release or /etc/fedora-release:

cat /etc/fedora-release 
Fedora release 7 (Moonshine)

BYTE* is probably a typedef for unsigned char*, but I can't say for sure. It would help if you tell us what BYTE is.

If BYTE* is unsigned char*, you can convert it to an std::string using the std::string range constructor, which will take two generic Iterators.

const BYTE* str1 = reinterpret_cast<const BYTE*> ("Hello World");
int len = strlen(reinterpret_cast<const char*>(str1));
std::string str2(str1, str1 + len);

That being said, are you sure this is a good idea? If BYTE is unsigned char it may contain non-ASCII characters, which can include NULLs. This will make strlen give an incorrect length.

It is explained pretty well here: Display a view from another controller in ASP.NET MVC

To quote @Womp:
By default, ASP.NET MVC checks first in \Views\[Controller_Dir]\, but after that, if it doesn't find the view, it checks in \Views\Shared.

ASP MVC's idea is "convention over configuration" which means moving the view to the shared folder is the way to go in such cases.

columnDefinition will override the sql DDL generated by hibernate for this particular column, it is non portable and depends on what database you are using. You can use it to specify nullable, length, precision, scale... ect.

Use:

  SELECT oi.orderid,
         SUM(oi.quantity * p.price) AS grand_total,
    FROM ORDERITEM oi
    JOIN PRODUCT p ON p.id = oi.productid
   WHERE oi.orderid = @OrderId
GROUP BY oi.orderid

Mind that if either oi.quantity or p.price is null, the SUM will return NULL.

This works without changing the validation mode.

You have to use a System.Web.Helpers.Validation.Unvalidated helper from System.Web.WebPages.dll. It is going to return a UnvalidatedRequestValues object which allows to access the form and QueryString without validation.

For example,

var queryValue = Server.UrlDecode(Request.Unvalidated("MyQueryKey"));

Works for me for MVC3 and .NET 4.

sed cannot match \n because the trailing newline is removed before the line is put into the pattern space but can match \r, so you can convert \r\n (dos) to \n (unix) by removing \r

sed -i 's/\r//g' file

Warning: this will change the original file

However, you cannot change from unix EOL to dos or old mac (\r) by this. More readings here:

How can I replace a newline (\n) using sed?

Based on @Nathan's answer above, but without needing to "remove the final union" and with the option to sort the output, I use the following SQL. It generates another SQL statement which then just run:

select CONCAT( 'select * from (\n', group_concat( single_select SEPARATOR ' UNION\n'), '\n ) Q order by Q.exact_row_count desc') as sql_query
from (
    SELECT CONCAT(
        'SELECT "', 
        table_name, 
        '" AS table_name, COUNT(1) AS exact_row_count
        FROM `', 
        table_schema,
        '`.`',
        table_name, 
        '`'
    ) as single_select
    FROM INFORMATION_SCHEMA.TABLES 
    WHERE table_schema = 'YOUR_SCHEMA_NAME'
      and table_type = 'BASE TABLE'
) Q 

You do need a sufficiently large value of group_concat_max_len server variable but from MariaDb 10.2.4 it should default to 1M.

you can 'invoke' alternative bindings on Y this way:

...registered(X, Y), (Y=ct101; Y=ct102; Y=ct103).

Note the parenthesis are required to keep the correct execution control flow. The ;/2 it's the general or operator. For your restricted use you could as well choice the more idiomatic

...registered(X, Y), member(Y, [ct101,ct102,ct103]).

that on backtracking binds Y to each member of the list.

edit I understood with a delay your last requirement. If you want that Y match all 3 values the or is inappropriate, use instead

...registered(X, ct101), registered(X, ct102), registered(X, ct103).

or the more compact

...findall(Y, registered(X, Y), L), sort(L, [ct101,ct102,ct103]).

findall/3 build the list in the very same order that registered/2 succeeds. Then I use sort to ensure the matching.

...setof(Y, registered(X, Y), [ct101,ct102,ct103]).

setof/3 also sorts the result list

I am using django==1.11. The answer get the most vote is actually wrong. Checking the document from django, it says:

initial -- A value to use in this Field's initial display. This value is not used as a fallback if data isn't given.

And if you dig into the code of form validation process, you will find that, for each fields, form will call it's widget's value_from_datadict to get actual value, so this is the place where we can inject default value.

To do this for BooleanField, we can inherit from CheckboxInput, override default value_from_datadict and init function.

class CheckboxInput(forms.CheckboxInput):
    def __init__(self, default=False, *args, **kwargs):
        super(CheckboxInput, self).__init__(*args, **kwargs)
        self.default = default

    def value_from_datadict(self, data, files, name):
        if name not in data:
            return self.default
        return super(CheckboxInput, self).value_from_datadict(data, files, name)

Then use this widget when creating BooleanField.

class ExampleForm(forms.Form):
    bool_field = forms.BooleanField(widget=CheckboxInput(default=True), required=False)

You do not need to use the while True: loop in this case. There is a much simpler way to use the time condition directly:

import time

# timeout variable can be omitted, if you use specific value in the while condition
timeout = 300   # [seconds]

timeout_start = time.time()

while time.time() < timeout_start + timeout:
    test = 0
    if test == 5:
        break
    test -= 1

A cookie is basically just an item in a dictionary. Each item has a key and a value. For authentication, the key could be something like 'username' and the value would be the username. Each time you make a request to a website, your browser will include the cookies in the request, and the host server will check the cookies. So authentication can be done automatically like that.

To set a cookie, you just have to add it to the response the server sends back after requests. The browser will then add the cookie upon receiving the response.

There are different options you can configure for the cookie server side, like expiration times or encryption. An encrypted cookie is often referred to as a signed cookie. Basically the server encrypts the key and value in the dictionary item, so only the server can make use of the information. So then cookie would be secure.

A browser will save the cookies set by the server. In the HTTP header of every request the browser makes to that server, it will add the cookies. It will only add cookies for the domains that set them. Example.com can set a cookie and also add options in the HTTP header for the browsers to send the cookie back to subdomains, like sub.example.com. It would be unacceptable for a browser to ever sends cookies to a different domain.

This should work:

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

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

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

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

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

#include <cmath>

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

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

I had this problem with version 6.7.4 and resolved it by installing version 6.5.6.

My setup is Win 2008 R2 SP1 Data Center edition, SQL Server 2008 R2 with Business Intelligence Development Studio (VS2008). Very basic install.

When I was installing 6.7.4, i could not even see the MySQL provider as a choice. However, when i looked into the machine.config file, I saw references for MySQL role provider etc, but no entry was added in the .

I had the same issue. after adding below code to my app.js file it fixed.

var cors = require('cors')
app.use(cors());

Yes, multiple calls to where() is a perfectly valid way to achieve this.

$this->db->where('username',$username);
$this->db->where('status',$status);

You can change the background color of the tab by this attribute

<android.support.design.widget.TabLayout
android:id="@+id/tabs"
style="@style/CategoryTab"
android:layout_width="match_parent"
android:layout_height="wrap_content"
'android:background="@color/primary_color"/>'

This error occurred for me when I mistakenly added a comment following a line continuation character in VB.Net. I removed the comment and the problem went away.

You simply need to make cab a string:

cab = '6176'

As the error message states, you cannot do <int> in <string>:

>>> 1 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>> 

because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").

In fact, Python only allows you to use the in operator with a right operand of type string if the left operand is also of type string:

>>> '1' in '123'  # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list
>>>
>>> 1.0 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not float
>>>
>>> {} in '123'
Traceback (most recent call last):

Using an example data.frame and example function (just +1 to all values)

A <- function(x) x + 1
wifi <- data.frame(replicate(9,1:4))
wifi

#  X1 X2 X3 X4 X5 X6 X7 X8 X9
#1  1  1  1  1  1  1  1  1  1
#2  2  2  2  2  2  2  2  2  2
#3  3  3  3  3  3  3  3  3  3
#4  4  4  4  4  4  4  4  4  4

data.frame(wifi[1:3], apply(wifi[4:9],2, A) )
#or
cbind(wifi[1:3], apply(wifi[4:9],2, A) )

#  X1 X2 X3 X4 X5 X6 X7 X8 X9
#1  1  1  1  2  2  2  2  2  2
#2  2  2  2  3  3  3  3  3  3
#3  3  3  3  4  4  4  4  4  4
#4  4  4  4  5  5  5  5  5  5

Or even:

data.frame(wifi[1:3], lapply(wifi[4:9], A) )
#or
cbind(wifi[1:3], lapply(wifi[4:9], A) )

#  X1 X2 X3 X4 X5 X6 X7 X8 X9
#1  1  1  1  2  2  2  2  2  2
#2  2  2  2  3  3  3  3  3  3

#4  4  4  4  5  5  5  5  5  5

As specified here You can update the index:

git update-index --assume-unchanged /path/to/file

By doing this, the files will not show up in git status or git diff.

To begin tracking the files again you can run:

git update-index --no-assume-unchanged /path/to/file

You need to pass the parameters, try this:

doskey np=notepad++.exe $*

Edit (responding to Romonov's comment) Q: Is there any way I can make the command prompt remember so I don't have to run this each time I open a new command prompt?

doskey is a textual command that is interpreted by the command processor (e.g. cmd.exe), it can't know to modify state in some other process (especially one that hasn't started yet).

People that use doskey to setup their initial command shell environments typically use the /K option (often via a shortcut) to run a batch file which does all the common setup (like- set window's title, colors, etc).

cmd.exe /K env.cmd

env.cmd:

title "Foo Bar"
doskey np=notepad++.exe $*
...

You can find the log within you Magento root directory under

var/log

there are two types of log files system.log and exception.log

you need to give the correct permission to var folder, then enable logging from your Magento admin by going to

System > Configuration> Developer > Log Settings > Enable = Yes

system.log is used for general debugging and catches almost all log entries from Magento, including warning, debug and errors messages from both native and custom modules.

exception.log is reserved for exceptions only, for example when you are using try-catch statement.

To output to either the default system.log or the exception.log see the following code examples:

Mage::log('My log entry');
Mage::log('My log message: '.$myVariable);
Mage::log($myArray);
Mage::log($myObject);
Mage::logException($e);

You can create your own log file for more debugging

Mage::log('My log entry', null, 'mylogfile.log');

The same issue happened to me. You need to check out your server.js file where you are setting your listening port. Change port number wisely in all places, and it will solve your issue hopefully.

You have to initialize variables before using them.?

If you try to evaluate the variables before initializing them you'll run into: FailedPreconditionError: Attempting to use uninitialized value tensor.

The easiest way is initializing all variables at once using: tf.global_variables_initializer()

init = tf.global_variables_initializer()
with tf.Session() as sess:
    sess.run(init)

You use sess.run(init) to run the initializer, without fetching any value.

To initialize only a subset of variables, you use tf.variables_initializer() listing the variables:

var_ab = tf.variables_initializer([a, b], name="a_and_b")
with tf.Session() as sess:
    sess.run(var_ab)

You can also initialize each variable separately using tf.Variable.initializer

# create variable W as 784 x 10 tensor, filled with zeros
W = tf.Variable(tf.zeros([784,10])) with tf.Session() as sess:
    sess.run(W.initializer)

I don't believe there is a way to ignore a file in the repository. We often run into this with web.config and other configuration files.

Although not perfect, the solution I most often see and use is to have .default file and an nant task to create local copies.

For example, in the repo is a file called web.config.default that has default values. Then create a nant task that will rename all the web.config.default files to web.config that can then be customized to local values. This task should be called when a new working copy is retrieved or a build is run.

You'll also need to ignore the web.config file that is created so that it isn't committed to the repository.

I use this query in order to retrieve the server name of my Oracle database.

SELECT program FROM v$session WHERE program LIKE '%(PMON)%';

You need to install the php-pgsql package or whatever it's called for your platform. Which I don't think you said by the way.

On Ubuntu and Debian:

sudo apt-get install php5-pgsql

As stated in the JQuery documentation

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

 $("#file-upload").change(function () {

    var validExtensions = ["jpg","pdf","jpeg","gif","png"]
    var file = $(this).val().split('.').pop();
    if (validExtensions.indexOf(file) == -1) {
        alert("Only formats are allowed : "+validExtensions.join(', '));
    }

});

Here I have tried this CSS for all major browser & tested: Custom color are working fine on scrollbar.

Yes, there are limitations on several versions of different browsers.

I already had the one condition from this answer (I don't know why)

https://stackoverflow.com/a/27295145/1175496

That is, my PATH already included %APPDATA%\npm

In my case, the problem was npm was not installing modules there (again, I don't know why)

Therefore I needed to do this:

$ npm config set prefix -g %APPDATA%/npm

After that, running $ npm install -g gulp (or installing any other module) put the module in the place where PATH expects it.

If you're testing for an empty string:

if(myVar === ''){ // do stuff };

If you're checking for a variable that has been declared, but not defined:

if(myVar === null){ // do stuff };

If you're checking for a variable that may not be defined:

if(myVar === undefined){ // do stuff };

If you're checking both i.e, either variable is null or undefined:

if(myVar == null){ // do stuff };

Are you looking for the syntax to open them:

Dim wkbk As Workbook

Set wkbk = Workbooks.Open("C:\MyDirectory\mysheet.xlsx")

Then, you can use wkbk.Sheets(1).Range("3:3") (or whatever you need)

I personally use following approach to sort dates.

let array = ["July 11, 1960", "February 1, 1974", "July 11, 1615", "October 18, 1851", "November 12, 1995"];

array.sort(function(date1, date2) {
   date1 = new Date(date1);
   date2 = new Date(date2);
   if (date1 > date2) return 1;
   if (date1 < date2) return -1;
})

Another example which uses function in ref rather than string

class List extends React.Component {
  constructor(props) {
    super(props);
    this.state = { items:[], index: 0 };
    this._nodes = new Map();

    this.handleAdd = this.handleAdd.bind(this);
    this.handleRemove = this.handleRemove.bind(this);
   }

  handleAdd() {
    let startNumber = 0;
    if (this.state.items.length) {
      startNumber = this.state.items[this.state.items.length - 1];
    }

    let newItems = this.state.items.splice(0);
    for (let i = startNumber; i < startNumber + 100; i++) {
      newItems.push(i);
    }

    this.setState({ items: newItems });
  }

  handleRemove() {
    this.setState({ items: this.state.items.slice(1) });
  }

  handleShow(i) {
    this.setState({index: i});
    const node = this._nodes.get(i);
    console.log(this._nodes);
    if (node) {
      ReactDOM.findDOMNode(node).scrollIntoView({block: 'end', behavior: 'smooth'});
    }
  }

  render() {
    return(
      <div>
        <ul>{this.state.items.map((item, i) => (<Item key={i} ref={(element) => this._nodes.set(i, element)}>{item}</Item>))}</ul>
        <button onClick={this.handleShow.bind(this, 0)}>0</button>
        <button onClick={this.handleShow.bind(this, 50)}>50</button>
        <button onClick={this.handleShow.bind(this, 99)}>99</button>
        <button onClick={this.handleAdd}>Add</button>
        <button onClick={this.handleRemove}>Remove</button>
        {this.state.index}
      </div>
    );
  }
}

class Item extends React.Component
{
  render() {
    return (<li ref={ element => this.listItem = element }>
      {this.props.children}
    </li>);
  }
}

This is what I used for similar type of use case as yours.

<style type="text/css">
#element1 {display:inline-block; width:45%; padding:10px}
#element2 {display:inline-block; width:45%; padding:10px}
</style>

<div id="element1">
 element 1 markup
</div>
<div id="element2">
 element 2 markup
</div>

Adjust your width and padding as per your requirement. Note - Do not exceed 'width' more than 100% altogether (ele1_width+ ele2_width) to add 'padding', keep it less than 100%.

This should get you for starting with two letters and ending with two numbers.

[A-Za-z]{2}(.*)[0-9]{2}

If you know it will always be just two and two you can

[A-Za-z]{2}[0-9]{2}

Just want to give one example why we decided to store image in DB not files or CDN, it is storing images of signatures.

We have tried to do so via CDN, cloud storage, files, and finally decided to store in DB and happy about the decision as it was proven us right in our subsequent events when we moved, upgraded our scripts and migrated the sites serveral times.

For my case, we wanted the signatures to be with the records that belong to the author of documents.

Storing in files format risks missing them or deleted by accident.

We store it as a blob binary format in MySQL, and later as based64 encoded image in a text field. The decision to change to based64 was due to smaller size as result for some reason, and faster loading. Blob was slowing down the page load for some reason.

In our case, this solution to store signature images in DB, (whether as blob or based64), was driven by:

1. Most signature images are very small.
2. We don't need to index the signature images stored in DB.
3. Index is done on the primary key.
4. We may have to move or switch servers, moving physical images files to different servers, may cause the images not found due to links change.
5. it is embarrassed to ask the author to re-sign their signatures.
6. it is more secured saving in the DB as compared to exposing it as files which can be downloaded if security is compromised. Storing in DB allows us better control over its access.
7. any future migrations, change of web design, hosting, servers, we have zero worries about reconcilating the signature file names against the physical files, it is all in the DB!

You can simple make use of lapply or sapply builtin functions.

lapply will return you a list -

lapply(dataframe,class)

while sapply will take the best possible return type ex. Vector etc -

sapply(dataframe,class)

Both the commands will return you all the column names with their respective class.

Synchronized Map:

Synchronized Map is also not very different than Hashtable and provides similar performance in concurrent Java programs. Only difference between Hashtable and SynchronizedMap is that SynchronizedMap is not a legacy and you can wrap any Map to create it’s synchronized version by using Collections.synchronizedMap() method.

ConcurrentHashMap:

The ConcurrentHashMap class provides a concurrent version of the standard HashMap. This is an improvement on the synchronizedMap functionality provided in the Collections class.

Unlike Hashtable and Synchronized Map, it never locks whole Map, instead it divides the map in segments and locking is done on those. It perform better if number of reader threads are greater than number of writer threads.

ConcurrentHashMap by default is separated into 16 regions and locks are applied. This default number can be set while initializing a ConcurrentHashMap instance. When setting data in a particular segment, the lock for that segment is obtained. This means that two updates can still simultaneously execute safely if they each affect separate buckets, thus minimizing lock contention and so maximizing performance.

ConcurrentHashMap doesn’t throw a ConcurrentModificationException

ConcurrentHashMap doesn’t throw a ConcurrentModificationException if one thread tries to modify it while another is iterating over it

Difference between synchornizedMap and ConcurrentHashMap

Collections.synchornizedMap(HashMap) will return a collection which is almost equivalent to Hashtable, where every modification operation on Map is locked on Map object while in case of ConcurrentHashMap, thread-safety is achieved by dividing whole Map into different partition based upon concurrency level and only locking particular portion instead of locking whole Map.

ConcurrentHashMap does not allow null keys or null values while synchronized HashMap allows one null keys.

Depending on which event you actually want to use (textbox change, or button click), you can try this:

HTML:

<input id="color" type="text" onchange="changeBackground(this);" />
<br />
<span id="coltext">This text should have the same color as you put in the text box</span>

JS:

function changeBackground(obj) {
    document.getElementById("coltext").style.color = obj.value;
}

DEMO: http://jsfiddle.net/6pLUh/

One minor problem with the button was that it was a submit button, in a form. When clicked, that submits the form (which ends up just reloading the page) and any changes from JavaScript are reset. Just using the onchange allows you to change the color based on the input.

In node.js we can use node-geocoder npm module to get address from lat, lng.,

geo.js

var NodeGeocoder = require('node-geocoder');

var options = {
  provider: 'google',
  httpAdapter: 'https', // Default
  apiKey: ' ', // for Mapquest, OpenCage, Google Premier
  formatter: 'json' // 'gpx', 'string', ...
};

var geocoder = NodeGeocoder(options);

geocoder.reverse({lat:28.5967439, lon:77.3285038}, function(err, res) {
  console.log(res);
});

output:

node geo.js

[ { formattedAddress: 'C-85B, C Block, Sector 8, Noida, Uttar Pradesh 201301, India',
    latitude: 28.5967439,

None of these solutions worked for what I needed which was a ScrollView set to wrap_content but having a maxHeight so it would stop expanding after a certain point and start scrolling. I just simply overrode the onMeasure method in ScrollView.

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    heightMeasureSpec = MeasureSpec.makeMeasureSpec(300, MeasureSpec.AT_MOST);
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

This might not work in all situations, but it certainly gives me the results needed for my layout. And it also addresses the comment by madhu.

If some layout present below the scrollview then this trick wont work – madhu Mar 5 at 4:36

Assuming your code above is the actual code, you have two problems:

1) your if statements need to be '==', not '='. You want to do comparison, not assignment.

2) The second if should be an 'else if'. Otherwise when it's false, you will set it to true, then the second if will be evaluated, and you'll set it back to false, as you describe

if (a == false) {
  a = true;
} else if (a == true) {
  a = false;
}

Another thing that would make it even simpler is the '!' operator:

a = !a;

will switch the value of a.

targetList = list1.Concat(list2).ToList();

It's working fine I think so. As previously said, Concat returns a new sequence and while converting the result to List, it does the job perfectly.

I read all the above answers and those are actually good.

look at this code:

for i in range(1, 4):
    print("Before change:", i)
    i = 20 # changing i variable
    print("After change:", i) # this line will always print 20

When we execute above code the output is like below,

Before Change: 1
After change: 20
Before Change: 2
After change: 20
Before Change: 3
After change: 20

in python for loop is not trying to increase i value. for loop is just assign values to i which we gave. Using range(4) what we are doing is we give the values to for loop which need assign to the i.

You can use while loop instead of for loop to do same thing what you want,

i = 0
while i < 6:
    print(i)
    j = 0
    while j < 5:
        i += 2 # to increase `i` by 2

This will give,

0
2
4

Thank you !

Moving to local folder is the quickest solution, nothing else worked for me esp because I was not admin on my system (can't edit registery etc), which is a typical case in a work environment.

Create a folder in C:\help drive, lets call it help and copy the files there and open.

Do not copy to mydocuments or anywhere else, those locations are usually on network drive in office setup and will not work.

Here is a script (works for an arbitrary number of specified files (not just all in the working directory), without additional files, also works for .mov; tested on macOS):

#!/bin/bash

if [ $# -lt 1 ]; then

After I plotted all the lines, I was able to set the transparency of all of them as follows:

for l in fig_field.gca().lines:
    l.set_alpha(.7)

EDIT: please see Joe's answer in the comments.

You need to give the body and the html a height too. Otherwise, the body will only be as high as its contents (the single div), and 50% of that will be half the height of this div.

Updated fiddle: http://jsfiddle.net/j8bsS/5/

What seems to be confusing this thread is the difference between:

$('.selector').append("<input type='text'/>"); 

Which appends the target element as a child of the .selector.

And

$("<input type='text' />").appendTo('.selector');

Which appends the target element as a child of the .selector.

Note how the position of the target element & the .selector change when using the different methods.

What you want to do is this:

$(function() {

  // append input control at start of form
  $("<input type='text' value='' />")
     .attr("id", "myfieldid")
     .attr("name", "myfieldid")
     .prependTo("#form-0");

  // OR

  // append input control at end of form
  $("<input type='text' value='' />")
     .attr("id", "myfieldid")
     .attr("name", "myfieldid")
     .appendTo("#form-0");

  // OR

  // see .after() or .before() in the api.jquery.com library

});

Converting the WHOLE Exception To a String

Calling Exception.ToString() gives you more information than just using the Exception.Message property. However, even this still leaves out lots of information, including:

1. The Data collection property found on all exceptions.
2. Any other custom properties added to the exception.

There are times when you want to capture this extra information. The code below handles the above scenarios. It also writes out the properties of the exceptions in a nice order. It's using C# 7 but should be very easy for you to convert to older versions if necessary. See also this related answer.

Top Tip - Logging Exceptions

Most people will be using this code for logging. Consider using Serilog with my Serilog.Exceptions NuGet package which also logs all properties of an exception but does it faster and without reflection in the majority of cases. Serilog is a very advanced logging framework which is all the rage at the time of writing.

Top Tip - Human Readable Stack Traces

You can use the Ben.Demystifier NuGet package to get human readable stack traces for your exceptions or the serilog-enrichers-demystify NuGet package if you are using Serilog.

Using a cookie to provide the CSRF token to the client does not allow a successful attack because the attacker cannot read the value of the cookie and therefore cannot put it where the server-side CSRF validation requires it to be.

The attacker will be able to cause a request to the server with both the auth token cookie and the CSRF cookie in the request headers. But the server is not looking for the CSRF token as a cookie in the request headers, it's looking in the payload of the request. And even if the attacker knows where to put the CSRF token in the payload, they would have to read its value to put it there. But the browser's cross-origin policy prevents reading any cookie value from the target website.

The same logic does not apply to the auth token cookie, because the server is expects it in the request headers and the attacker does not have to do anything special to put it there.

Although Chang's answer explains how to plot multiple times on the same figure, in this case you might be better off in this case using a groupby and unstacking:

(Assuming you have this in dataframe, with datetime index already)

In [1]: df
Out[1]:
            value  
datetime                         
2010-01-01      1  
2010-02-01      1  
2009-01-01      1  

# create additional month and year columns for convenience
df['Month'] = map(lambda x: x.month, df.index)
df['Year'] = map(lambda x: x.year, df.index)    

In [5]: df.groupby(['Month','Year']).mean().unstack()
Out[5]:
       value      
Year    2009  2010
Month             
1          1     1
2        NaN     1

Now it's easy to plot (each year as a separate line):

df.groupby(['Month','Year']).mean().unstack().plot()

Just use if and env.BRANCH_NAME, example:

    if (env.BRANCH_NAME == "deployment") {                                          
        ... do some build ...
    } else {                                   
        ... do something else ...
    }                                                                       

there is no CSS selector for selecting a parent of a selected child.

you could do it with JavaScript

I very much liked John's answer, but I'd like to give it with some changes to those that want to test some client//server configuration by running a client TCP on the USB connected Mobile and a server on the local PC.

First it's quite obvious that the 10.0.2.2 won't work because this is a REAL hardware mobile and not a simulator.

So Follow John's instructions:

• Unplug all network cables on PC and turn off wifi.
• Turn off wifi on the android device
• Connect android device to pc via USB

• Turn on the "USB Tethering" (USB Modem/ USB Cellular Modem / USB ????? ????? ??????) in the android menu. (Under networks->more...->Tethering and portable hotspot")

  • This USB connection will act as a DHCP server for you single PC connection, so it'll assign your PC a dedicated (dynamic) IP in its local USB network. Now all you have to do is tell the client application this IP and port.

• Get the IP of your PC (that has been assigned by the USB tether cable.) (open command prompt and type "ipconfig" then look for the IP that the USB network adapter has assigned, in Linux its ifconfig or Ubuntu's "Connection information" etc..)

• Tell the application to connect to that IP (i.e. 192.168.42.87) with something like (Java - client side):

  String        serverIP      = "192.168.42.87";
  int           serverPort    = 5544;
  InetAddress   serverAddress = InetAddress.getByName(serverIP);
  Socket        socket         = new Socket(serverAddress, serverPort);
  ...
  

  Enjoy..

In Swift 5:

extension Int{
    func expo(_ power: Int) -> Int {
        var result = 1
        var powerNum = power
        var tempExpo = self
        while (powerNum != 0){
        if (powerNum%2 == 1){
            result *= tempExpo
        }
        powerNum /= 2
        tempExpo *= tempExpo
        }
        return result
    }
}

Use like this

2.expo(5) // pow(2, 5)

Thanks to @Paul Buis's answer.

Working with a dictionary ->level2 above comes from a dictionary in my case (just in case anybody will find it useful) Trying the first example I stumbled over this error: "This document already has a 'DocumentElement' node." I was inspired by the answer here

and edited my code: (xmlDoc.DocumentElement.AppendChild(body))

//a dictionary:
Dictionary<string, string> Level2Data 
{
    {"level2", "text"},
    {"level2", "other text"},
    {"same_level2", "more text"}
}
//xml Decalration:
XmlDocument xmlDoc = new XmlDocument();
XmlDeclaration xmlDeclaration = xmlDoc.CreateXmlDeclaration("1.0", "UTF-8", null);
XmlElement root = xmlDoc.DocumentElement;
xmlDoc.InsertBefore(xmlDeclaration, root);
// add body
XmlElement body = xmlDoc.CreateElement(string.Empty, "body", string.Empty);
xmlDoc.AppendChild(body);
XmlElement body = xmlDoc.CreateElement(string.Empty, "body", string.Empty);
xmlDoc.DocumentElement.AppendChild(body); //without DocumentElement ->ERR



foreach (KeyValuePair<string, string> entry in Level2Data)
{
    //write to xml: - it works version 1.
    XmlNode keyNode = xmlDoc.CreateElement(entry.Key); //open TAB
    keyNode.InnerText = entry.Value;
    body.AppendChild(keyNode); //close TAB

    //Write to xmml verdion 2: (uncomment the next 4 lines and comment the above 3 - version 1
    //XmlElement key = xmlDoc.CreateElement(string.Empty, entry.Key, string.Empty);
    //XmlText value = xmlDoc.CreateTextNode(entry.Value);
    //key.AppendChild(value);
    //body.AppendChild(key);
}

Both versions (1 and 2 inside foreach loop) give the output:

<?xml version="1.0" encoding="UTF-8"?>
<body>
    <level1>
        <level2>text</level2>
        <level2>ther text</level2>
         <same_level2>more text</same_level2>
    </level1>
</body>

(Note: third line "same level2" in dictionary can be also level2 as the others but I wanted to ilustrate the advantage of the dictionary - in my case I needed level2 with different names.

// if you want to hide back button use below code

    //hide back button
    automaticallyImplyLeading: false,
   ),
  body: Center(
    child: Container(),
  ),
);
}
}

// if you want to hide back button and stop the pop action use below code

      automaticallyImplyLeading: false,
    ),

          mainAxisAlignment: MainAxisAlignment.center,
          crossAxisAlignment: CrossAxisAlignment.center,
          children: <Widget>[
            RaisedButton(
              child: Text('Back'),
              onPressed: () {
                Navigator.pop(context);
              },
            ),
          ],
        )
    ),
  ),
);
 }

you can use enumerate keeping the ind/index of the elements is in vm, if you make vm a set you will also have 0(1) lookups:

vm = {-1, -1, -1, -1}

print([ind if q in vm else 9999 for ind,ele in enumerate(vm) ])

If you need to have jquery use !important for more than one item, this is how you would do it.

e.g. set an img tags max-width and max-height to 500px each

$('img').css('cssText', "max-width: 500px !important;' + "max-height: 500px !important;');

Try this: tar -cf file.tar file-to-compress ; xz -z file.tar

Note:

1. tar.gz and tar.xz are not the same; xz provides better compression.
2. Don't use pipe | because this runs commands simultaneously. Using ; or & executes commands one after another.

You can do this way -

int[] terms = new int[400];
for (int runs = 0; runs < 400; runs++)
{
    terms[runs] = value;
}

Alternatively, you can use Lists - the advantage with lists being, you don't need to know the array size when instantiating the list.

List<int> termsList = new List<int>();
for (int runs = 0; runs < 400; runs++)
{
    termsList.Add(value);
}

// You can convert it back to an array if you would like to
int[] terms = termsList.ToArray();

Edit: a) for loops on List<T> are a bit more than 2 times cheaper than foreach loops on List<T>, b) Looping on array is around 2 times cheaper than looping on List<T>, c) looping on array using for is 5 times cheaper than looping on List<T> using foreach (which most of us do).

You want either auto-fit or auto-fill inside the repeat() function:

grid-template-columns: repeat(auto-fit, 186px);

The difference between the two becomes apparent if you also use a minmax() to allow for flexible column sizes:

grid-template-columns: repeat(auto-fill, minmax(186px, 1fr));

This allows your columns to flex in size, ranging from 186 pixels to equal-width columns stretching across the full width of the container. auto-fill will create as many columns as will fit in the width. If, say, five columns fit, even though you have only four grid items, there will be a fifth empty column:

Using auto-fit instead will prevent empty columns, stretching yours further if necessary:

Simply try something like

Arrays.asList(array)

If you don't know the numbers of the clusters k to provide as parameter to k-means so there are four ways to find it automaticaly:

• G-means algortithm: it discovers the number of clusters automatically using a statistical test to decide whether to split a k-means center into two. This algorithm takes a hierarchical approach to detect the number of clusters, based on a statistical test for the hypothesis that a subset of data follows a Gaussian distribution (continuous function which approximates the exact binomial distribution of events), and if not it splits the cluster. It starts with a small number of centers, say one cluster only (k=1), then the algorithm splits it into two centers (k=2) and splits each of these two centers again (k=4), having four centers in total. If G-means does not accept these four centers then the answer is the previous step: two centers in this case (k=2). This is the number of clusters your dataset will be divided into. G-means is very useful when you do not have an estimation of the number of clusters you will get after grouping your instances. Notice that an inconvenient choice for the "k" parameter might give you wrong results. The parallel version of g-means is called p-means. G-means sources: source 1 source 2 source 3

• x-means: a new algorithm that efficiently, searches the space of cluster locations and number of clusters to optimize the Bayesian Information Criterion (BIC) or the Akaike Information Criterion (AIC) measure. This version of k-means finds the number k and also accelerates k-means.

• Online k-means or Streaming k-means: it permits to execute k-means by scanning the whole data once and it finds automaticaly the optimal number of k. Spark implements it.

• MeanShift algorithm: it is a nonparametric clustering technique which does not require prior knowledge of the number of clusters, and does not constrain the shape of the clusters. Mean shift clustering aims to discover “blobs” in a smooth density of samples. It is a centroid-based algorithm, which works by updating candidates for centroids to be the mean of the points within a given region. These candidates are then filtered in a post-processing stage to eliminate near-duplicates to form the final set of centroids. Sources: source1, source2, source3

From the output of java -X:

    -Xloggc:<file>    log GC status to a file with time stamps

Documented here:

-Xloggc:filename

Sets the file to which verbose GC events information should be redirected for logging. The information written to this file is similar to the output of -verbose:gc with the time elapsed since the first GC event preceding each logged event. The -Xloggc option overrides -verbose:gc if both are given with the same java command.

Example:

    -Xloggc:garbage-collection.log

So the output looks something like this:

0.590: [GC 896K->278K(5056K), 0.0096650 secs]
0.906: [GC 1174K->774K(5056K), 0.0106856 secs]
1.320: [GC 1670K->1009K(5056K), 0.0101132 secs]
1.459: [GC 1902K->1055K(5056K), 0.0030196 secs]
1.600: [GC 1951K->1161K(5056K), 0.0032375 secs]
1.686: [GC 1805K->1238K(5056K), 0.0034732 secs]
1.690: [Full GC 1238K->1238K(5056K), 0.0631661 secs]
1.874: [GC 62133K->61257K(65060K), 0.0014464 secs]

Warning

From @sidharth: "caused my lava iris alfa to go into a bootloop :("

For my Motorola Nexus 6 running Android Marshmallow 6.0.1 I did:

None of other answers worked. This is what I have done:

1. deleted my certificate from keychain;
2. opened Xcode it rebuild certificate;
3. ran app on device successfully.

Based on the manual page:

# Log in to the server.  This only needs to be done once.
wget --save-cookies cookies.txt \
     --keep-session-cookies \
     --post-data 'user=foo&password=bar' \
     --delete-after \
     http://server.com/auth.php

# Now grab the page or pages we care about.
wget --load-cookies cookies.txt \
     http://server.com/interesting/article.php

Make sure the --post-data parameter is properly percent-encoded (especially ampersands!) or the request will probably fail. Also make sure that user and password are the correct keys; you can find out the correct keys by sleuthing the HTML of the login page (look into your browser’s “inspect element” feature and find the name attribute on the username and password fields).

May be I come later to answer but right now I'm facing with this... if helps there are one more solution (the way i solved it).

    var query2 = (
    from users in Repo.T_Benutzer
    join mappings in Repo.T_Benutzer_Benutzergruppen on mappings.BEBG_BE equals users.BE_ID into tmpMapp
    join groups in Repo.T_Benutzergruppen on groups.ID equals mappings.BEBG_BG into tmpGroups
    from mappings in tmpMapp.DefaultIfEmpty()
    from groups in tmpGroups.DefaultIfEmpty()
    select new
    {
         UserId = users.BE_ID
        ,UserName = users.BE_User
        ,UserGroupId = mappings.BEBG_BG
        ,GroupName = groups.Name
    }

);

By the way, I tried using the Stefan Steiger code which also helps but it was slower as hell.

This is one of the proposed solutions found in the article Jacob mentioned, and it worked great as a manual way to change the password without having to use the email reset.

1. In the DB table wp_users, add a key, like abc123 to the user_activation column.
2. Visit yoursite.com/wp-login.php?action=rp&key=abc123&login=yourusername
3. You will be prompted to enter a new password.

If you specifically want to use SwingX-WS, then have a look at XmlHttpRequest and JSONHttpRequest.

More on those classes in the XMLHttpRequest and Swing blog post.

While this isn't cloning, one simple way to get your result is to use the original object as the prototype of a new one.

You can do this using Object.create:

var obj = {a: 25, b: 50, c: 75};
var A = Object.create(obj);
var B = Object.create(obj);

A.a = 30;
B.a = 40;

alert(obj.a + " " + A.a + " " + B.a); // 25 30 40

This creates a new object in A and B that inherits from obj. This means that you can add properties without affecting the original.

To support legacy implementations, you can create a (partial) shim that will work for this simple task.

if (!Object.create)
    Object.create = function(proto) {
        function F(){}
        F.prototype = proto;
        return new F;
    }

It doesn't emulate all the functionality of Object.create, but it'll fit your needs here.

On problems try to open the images first with a program that is capable to read svg-images.
If that fails, then the svg-image is somehow corrupted.

I had that case and copied the svg-paths in a new svg-image and adjusted all details of the svg-tags.

I never tested the reason that it was not rendering but suppose that some invisible special signs caused the render-error. Getting sometimes files edited on Mac I had this issue in other context already.

Try this(need to get first IMEI always)

TelephonyManager mTelephony = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        if (ActivityCompat.checkSelfPermission(LoginActivity.this,Manifest.permission.READ_PHONE_STATE)!= PackageManager.PERMISSION_GRANTED) {

         return;
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                if (mTelephony.getPhoneCount() == 2) {
                    IME = mTelephony.getImei(0);
                }else{
                    IME = mTelephony.getImei();
                }
            }else{
                if (mTelephony.getPhoneCount() == 2) {
                    IME = mTelephony.getDeviceId(0);
                } else {
                    IME = mTelephony.getDeviceId();
                }
            }
        } else {
            IME = mTelephony.getDeviceId();
        }

Here is one way to do it.

Notepad++ v6.5

1. Search menu -> Find... -> Mark tab -> Find what: your search text, check Bookmark Line, then Mark All. This will bookmark all the lines with the search term, you'll see the blue circles in the margin.

2. Then Search menu -> Bookmark -> Remove Bookmarked Lines. This will delete all the bookmarked lines.

You can also use a regex to search. This method won't result in a blank line like John's and will actually delete the line.

Older Versions

1. Search menu -> Find... -> Find what: your search text, check Bookmark Line and click Find All.
2. Then Search -> Bookmark -> Remove Bookmarked Lines

Debian/Ubuntu handles this with a cronjob defined in /etc/cron.d/php5

# /etc/cron.d/php5: crontab fragment for php5
#  This purges session files older than X, where X is defined in seconds
#  as the largest value of session.gc_maxlifetime from all your php.ini
#  files, or 24 minutes if not defined.  See /usr/lib/php5/maxlifetime

# Look for and purge old sessions every 30 minutes

The maxlifetime script simply returns the number of minutes a session should be kept alive by checking php.ini, it looks like this

#!/bin/sh -e

max=1440

for ini in /etc/php5/*/php.ini; do
        cur=$(sed -n -e 's/^[[:space:]]*session.gc_maxlifetime[[:space:]]*=[[:space:]]*\([0-9]\+\).*$/\1/p' $ini 2>/dev/null || true);

        [ "$cur" -gt "$max" ] && max=$cur
done

Both async and defer scripts begin to download immediately without pausing the parser and both support an optional onload handler to address the common need to perform initialization which depends on the script.

The difference between async and defer centers around when the script is executed. Each async script executes at the first opportunity after it is finished downloading and before the window’s load event. This means it’s possible (and likely) that async scripts are not executed in the order in which they occur in the page. Whereas the defer scripts, on the other hand, are guaranteed to be executed in the order they occur in the page. That execution starts after parsing is completely finished, but before the document’s DOMContentLoaded event.

Sometimes you need to work with adjustments.

Don't use cast to long! Use nanoadjustment.

For example, using Oanda Java API for trading you can get datetime as UNIX format.

For example: 1592523410.590566943

    System.out.println("instant with nano = " + Instant.ofEpochSecond(1592523410, 590566943));
    System.out.println("instant = " + Instant.ofEpochSecond(1592523410));

you get:

instant with nano = 2020-06-18T23:36:50.590566943Z
instant = 2020-06-18T23:36:50Z

Also, use:

 Date date = Date.from( Instant.ofEpochSecond(1592523410, 590566943) );

Latest phpMyAdmin versions require mysqli extension and will no longer work with mysql one (note the extra "i" at the end of its name).

For PHP 5

sudo apt-get install php5-mysqli

For PHP 7.3

sudo apt-get install php7.3-mysqli

Will install package containing both old one and the new one, so afterwards all you need to do is to add

extension=mysqli.so

in your php.ini, under the subject Dynamic Extensions.

Restart apache:

sudo systemctl restart apache2

Authenitacate and press enter.

Should be done! If problem still occurs remove the browser cache.

<?php 
$link = mysqli_connect('localhost','root',''); 
if (!$link) { 
    die('Could not connect to MySQL: ' . mysqli_error()); 
} 
echo 'Connection OK'; mysqli_close($link); 
?>

This will solve your problem.

Alternative syntax using the -Not operator and depending on your preference for readability:

if( -Not (Test-Path -Path $TARGETDIR ) )
{
    New-Item -ItemType directory -Path $TARGETDIR
}

I do it like this <center></center>

<div class="form-actions">
            <center>
                    <button type="submit" class="submit btn btn-primary ">
                        Sign In <i class="icon-angle-right"></i>
                    </button>
            </center>
</div>

The accepted answer does not work in Jupyter (at least when using some libraries).

The Javascript solutions here only hide warnings that are already showing but not warnings that would be shown in the future.

To hide/unhide warnings in Jupyter and JupyterLab I wrote the following script that essentially toggles css to hide/unhide warnings.

%%javascript
(function(on) {
const e=$( "<a>Setup failed</a>" );
const ns="js_jupyter_suppress_warnings";
var cssrules=$("#"+ns);
if(!cssrules.length) cssrules = $("<style id='"+ns+"' type='text/css'>div.output_stderr { } </style>").appendTo("head");
e.click(function() {
    var s='Showing';  
    cssrules.empty()
    if(on) {
        s='Hiding';
        cssrules.append("div.output_stderr, div[data-mime-type*='.stderr'] { display:none; }");
    }
    e.text(s+' warnings (click to toggle)');
    on=!on;
}).click();
$(element).append(e);
})(true);

There are at least two possible situations:

1. you are deleting the same entity twice
2. you are deleting something that wasn't allocated

For the first one I strongly suggest NULL-ing all deleted pointers.

You have three options:

1. overload new and delete and track the allocations
2. yes, use gdb -- then you'll get a backtrace from your crash, and that'll probably be very helpful
3. as suggested -- use Valgrind -- it isn't easy to get into, but it will save you time thousandfold in the future...

Try this. It holds the color until another item is clicked.

<style type="text/css">

.activeElem{
 background-color:lightblue
}       
.desactiveElem{
 background-color:none
}       

}

</style>

<script type="text/javascript">
var activeElemId;
function activateItem(elemId) {
 document.getElementById(elemId).className="activeElem";
 if(null!=activeElemId) {
   document.getElementById(activeElemId).className="desactiveElem";
 }
 activeElemId=elemId;

}
</script>

<li id="aaa"><a href="#" onclick="javascript:activateItem('aaa');">AAA</a>
<li id="bbb"><a href="#" onClick="javascript:activateItem('bbb');">BBB</a>
<li id="ccc"><a href="#" onClick="javascript:activateItem('ccc');">CCC</a>

Take a look at NSXMLParser. It's a SAX-style parser. You should be able to use it to detect tags or other unwanted elements in the XML document and ignore them, capturing only pure text.

You can use Arrays.sort() method. Here's the example,

import java.util.Arrays;

public class Test 
{
    public static void main(String[] args) 
    {
        String arrString[] = { "peter", "taylor", "brooke", "frederick", "cameron" };
        orderedGuests(arrString);
    }

    public static void orderedGuests(String[] hotel)
    {
        Arrays.sort(hotel);
        System.out.println(Arrays.toString(hotel));
    }
}

Output

[brooke, cameron, frederick, peter, taylor]

You can also use translate(). If the third argument is too short, the corresponding characters from the second argument are deleted. Unlike regexp_replace() you don't need to worry about special characters. Source code.

I tried all of above. What helps me:

1. Download the mingw-get.
2. Setup it.
3. Add something like this C:\MinGW\bin to environment variables.
4. Launch (!important) git bash. Power shell, developer vs cmd, system cmd etc did'nt help.
5. Type mingw-get into command line.
6. After type mingw-get install mingw32-make.
7. Copy and paste all files from C:\MinGW\bin to folder where your Makefile is. Done! Now You might be able to use make-commands in this folder.

If you are using uniform 1.5 then use this simple trick to add or remove attribute of check
Just add value="check" in your checkbox's input field.
Add this code in uniform.js > function doCheckbox(elem){ > .click(function(){

if ( $(elem+':checked').val() == 'check' ) {
    $(elem).attr('checked','checked');           
}
else {
    $(elem).removeAttr('checked');
}   

if you not want to add value="check" in your input box because in some cases you add two checkboxes so use this

if ($(elem).is(':checked')) {
 $(elem).attr('checked','checked');
}    
else
{    
 $(elem).removeAttr('checked');
}

If you are using uniform 2.0 then use this simple trick to add or remove attribute of check
in this classUpdateChecked($tag, $el, options) { function change

if ($el.prop) {
    // jQuery 1.6+
    $el.prop(c, isChecked);
}

To

if ($el.prop) {
    // jQuery 1.6+
    $el.prop(c, isChecked);
    if (isChecked) {
        $el.attr(c, c);
    } else {
        $el.removeAttr(c);
    }

}

By referring this(http://www.excelforum.com/excel-programming-vba-macros/867665-application-cutcopymode-false.html) link the answer is as below:

Application.CutCopyMode=False is seen in macro recorder-generated code when you do a copy/cut cells and paste . The macro recorder does the copy/cut and paste in separate statements and uses the clipboard as an intermediate buffer. I think Application.CutCopyMode = False clears the clipboard. Without that line you will get the warning 'There is a large amount of information on the Clipboard....' when you close the workbook with a large amount of data on the clipboard.

With optimised VBA code you can usually do the copy/cut and paste operations in one statement, so the clipboard isn't used and Application.CutCopyMode = False isn't needed and you won't get the warning.

You can set the length of the regular expression pattern by using the {x,y} operator. {3,4} would match if the preceeding pattern occurs 3 or 4 times.

But I don't think you really need it. What will you do with a file named "This.is"?

Enhancement of Ben Brandt's answer to compensate even if the string starts with space by applying LTRIM(). Tried to edit his answer but rejected, so I am now posting it here separately.

DECLARE @test NVARCHAR(255)
SET @test = 'First Second'

SELECT SUBSTRING(LTRIM(@test),1,(CHARINDEX(' ',LTRIM(@test) + ' ')-1))

In my case I got the error only in VS 2015. When opening the project in VS 2017 the error was gone.

If you want to use one of the "Getting Started" templates from spring.io site, but you don't need any of the servlet-related stuff that comes with the "default" ("gs/spring-boot") template, you can try the scheduling-tasks template (whose pom* contains spring-boot-starter etc) instead:

https://spring.io/guides/gs/scheduling-tasks/

That gives you Spring Boot, and the app runs as a standalone (no servlets or spring-webmvc etc are included in the pom). Which is what you wanted (though you may need to add some JMS-specific stuff, as someone else points out already).

[* I'm using Maven, but assume that a Gradle build will work similarly].

Use this function from stringi package

> x <- 'hello stackoverflow'
> stri_sub(x,2)
[1] "ello stackoverflow"

if I got your question correct...

main() method is defined in the class below...

public class ToBeCalledClass{

   public static void main (String args[ ]) {
      System.out.println("I am being called");
   }
}

you want to call this main method in another class.

public class CallClass{

    public void call(){
       ToBeCalledClass.main(null);
    }
}

Quick note: if you want to do selection based on a partial string contained in the index, try the following:

df['stridx']=df.index
df[df['stridx'].str.contains("Hello|Britain")]

Assuming your page is available under "http://example.com"

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://example.com")

Select element by id:

inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')

Now you can simulate hitting ENTER:

inputElement.send_keys(Keys.ENTER)

or if it is a form you can submit:

inputElement.submit() 

Try to send an e-mail through that SMTP server manually/from an interactive mailer (e.g. Mozilla Thunderbird). From the errors, it seems the server won't accept your credentials. Is that SMTP running on the port, or is it SSL+SMTP? You don't seem to be using secure connection in the code you've posted, and I'm not sure if PHPMailer actually supports SSL+SMTP.

(First result of googling your SMTP server's hostname: http://podpora.ebola.cz/idx.php/0/006/article/Strucny-technicky-popis-nastaveni-sluzeb.html seems to say "SMTPs mail sending: secure SSL connection,port: 465" . )

It looks like PHPMailer does support SSL; at least from this. So, you'll need to change this:

define('SMTP_SERVER', 'smtp.ebola.cz');

into this:

define('SMTP_SERVER', 'ssl://smtp.ebola.cz');

var foo = 'somestring'; 

// bad example https://stackoverflow.com/questions/6484670/how-do-i-split-a-string-into-an-array-of-characters/38901550#38901550

var arr = foo.split(''); 
console.log(arr); // ["s", "o", "m", "e", "s", "t", "r", "i", "n", "g"]

// good example
var arr = Array.from(foo);
console.log(arr); // ["s", "o", "m", "e", "s", "t", "r", "i", "n", "g"]

// best
var arr = [...foo]
console.log(arr); // ["s", "o", "m", "e", "s", "t", "r", "i", "n", "g"]

max is a builtin function in python, which is used to get max value from a sequence, i.e (list, tuple, set, etc..)

print(max([9, 7, 12, 5]))

In Identity inspector change class name with the corresponding identifier and also In Attributes inspector modify Indentifier then it should work as expected.

The DFS-based variants with back edges will find cycles indeed, but in many cases it will NOT be minimal cycles. In general DFS gives you the flag that there is a cycle but it is not good enough to actually find cycles. For example, imagine 5 different cycles sharing two edges. There is no simple way to identify cycles using just DFS (including backtracking variants).

Johnson's algorithm is indeed gives all unique simple cycles and has good time and space complexity.

But if you want to just find MINIMAL cycles (meaning that there may be more then one cycle going through any vertex and we are interested in finding minimal ones) AND your graph is not very large, you can try to use the simple method below. It is VERY simple but rather slow compared to Johnson's.

So, one of the absolutely easiest way to find MINIMAL cycles is to use Floyd's algorithm to find minimal paths between all the vertices using adjacency matrix. This algorithm is nowhere near as optimal as Johnson's, but it is so simple and its inner loop is so tight that for smaller graphs (<=50-100 nodes) it absolutely makes sense to use it. Time complexity is O(n^3), space complexity O(n^2) if you use parent tracking and O(1) if you don't. First of all let's find the answer to the question if there is a cycle. The algorithm is dead-simple. Below is snippet in Scala.

  val NO_EDGE = Integer.MAX_VALUE / 2

  def shortestPath(weights: Array[Array[Int]]) = {
    for (k <- weights.indices;
         i <- weights.indices;
         j <- weights.indices) {
      val throughK = weights(i)(k) + weights(k)(j)
      if (throughK < weights(i)(j)) {
        weights(i)(j) = throughK
      }
    }
  }

Originally this algorithm operates on weighted-edge graph to find all shortest paths between all pairs of nodes (hence the weights argument). For it to work correctly you need to provide 1 if there is a directed edge between the nodes or NO_EDGE otherwise. After algorithm executes, you can check the main diagonal, if there are values less then NO_EDGE than this node participates in a cycle of length equal to the value. Every other node of the same cycle will have the same value (on the main diagonal).

To reconstruct the cycle itself we need to use slightly modified version of algorithm with parent tracking.

  def shortestPath(weights: Array[Array[Int]], parents: Array[Array[Int]]) = {
    for (k <- weights.indices;
         i <- weights.indices;
         j <- weights.indices) {
      val throughK = weights(i)(k) + weights(k)(j)
      if (throughK < weights(i)(j)) {
        parents(i)(j) = k
        weights(i)(j) = throughK
      }

Parents matrix initially should contain source vertex index in an edge cell if there is an edge between the vertices and -1 otherwise. After function returns, for each edge you will have reference to the parent node in the shortest path tree. And then it's easy to recover actual cycles.

All in all we have the following program to find all minimal cycles

  val NO_EDGE = Integer.MAX_VALUE / 2;

  def shortestPathWithParentTracking(
         weights: Array[Array[Int]],
         parents: Array[Array[Int]]) = {
    for (k <- weights.indices;
         i <- weights.indices;
         j <- weights.indices) {
      val throughK = weights(i)(k) + weights(k)(j)
      if (throughK < weights(i)(j)) {
        parents(i)(j) = parents(i)(k)
        weights(i)(j) = throughK
      }
    }
  }

  def recoverCycles(
         cycleNodes: Seq[Int], 
         parents: Array[Array[Int]]): Set[Seq[Int]] = {
    val res = new mutable.HashSet[Seq[Int]]()
    for (node <- cycleNodes) {
      var cycle = new mutable.ArrayBuffer[Int]()
      cycle += node
      var other = parents(node)(node)
      do {
        cycle += other
        other = parents(other)(node)
      } while(other != node)
      res += cycle.sorted
    }
    res.toSet
  }

and a small main method just to test the result

  def main(args: Array[String]): Unit = {
    val n = 3
    val weights = Array(Array(NO_EDGE, 1, NO_EDGE), Array(NO_EDGE, NO_EDGE, 1), Array(1, NO_EDGE, NO_EDGE))
    val parents = Array(Array(-1, 1, -1), Array(-1, -1, 2), Array(0, -1, -1))
    shortestPathWithParentTracking(weights, parents)
    val cycleNodes = parents.indices.filter(i => parents(i)(i) < NO_EDGE)
    val cycles: Set[Seq[Int]] = recoverCycles(cycleNodes, parents)
    println("The following minimal cycle found:")
    cycles.foreach(c => println(c.mkString))
    println(s"Total: ${cycles.size} cycle found")
  }

and the output is

The following minimal cycle found:
012
Total: 1 cycle found

I find internal to be far overused. you really should not be exposing certain functionailty only to certain classes that you would not to other consumers.

This in my opinion breaks the interface, breaks the abstraction. This is not to say it should never be used, but a better solution is to refactor to a different class or to be used in a different way if possible. However, this may not be always possible.

The reasons it can cause issues is that another developer may be charged with building another class in the same assembly that yours is. Having internals lessens the clarity of the abstraction, and can cause problems if being misused. It would be the same issue as if you made it public. The other class that is being built by the other developer is still a consumer, just like any external class. Class abstraction and encapsulation isnt just for protection for/from external classes, but for any and all classes.

Another problem is that a lot of developers will think they may need to use it elsewhere in the assembly and mark it as internal anyways, even though they dont need it at the time. Another developer then may think its there for the taking. Typically you want to mark private until you have a definative need.

But some of this can be subjective, and I am not saying it should never be used. Just use when needed.

As BalausC mentioned in a comment, you are probably looking for CSS (Cascading Style Sheets) not HTML attributes.

To position an element, a <table> in your case you want to use either padding or margins.

the difference between margins and paddings can be seen as the "box model":

Image from HTML Dog article on margins and padding http://www.htmldog.com/guides/cssbeginner/margins/.

I highly recommend the article above if you need to learn how to use CSS.

To move the table down and right I would use margins like so:

table{
    margin:25px 0 0 25px;
}

This is in shorthand so the margins are as follows:

margin: top right bottom left;

With Postgres 9.3+, just use the -> operator. For example,

SELECT data->'images'->'thumbnail'->'url' AS thumb FROM instagram;

see http://clarkdave.net/2013/06/what-can-you-do-with-postgresql-and-json/ for some nice examples and a tutorial.

JavaScript developers tend to refer to the above data-structure as either an object or hash instead of a Dictionary.

Your syntax above is wrong as you are initializing the users object as null. I presume this is a typo, as the code should read:

// Initialize users as a new hash.
var users = {};
users["182982"] = "...";

To retrieve all the values from a hash, you need to iterate over it using a for loop:

function getValues (hash) {
    var values = [];
    for (var key in hash) {

        // Ensure that the `key` is actually a member of the hash and not
        // a member of the `prototype`.
        // see: http://javascript.crockford.com/code.html#for%20statement
        if (hash.hasOwnProperty(key)) {
            values.push(key);
        }
    }
    return values;
};

If you plan on doing a lot of work with data-structures in JavaScript then the underscore.js library is definitely worth a look. Underscore comes with a values method which will perform the above task for you:

var values = _.values(users);

I don't use Angular myself, but I'm pretty sure there will be a convenience method build in for iterating over a hash's values (ah, there we go, Artem Andreev provides the answer above :))

function submitForm()
{
    if (testSubmit())
    {
        document.forms["myForm"].submit(); //first submit
        document.forms["myForm"].reset(); //and then reset the form values
    }
} </script> <body>
<form method="get" name="myForm">

    First Name: <input type="text" name="input1"/>
    <br/>
    Last Name: <input type="text" name="input2"/>
    <br/>
    <input type="button" value="Submit" onclick="submitForm()"/>
</form>

A simple solution for a very common problem

                 // DECLARATION
                HttpContext context = HttpContext.Current;
                DataTable dt_ShoppingBasket = context.Session["Shopping_Basket"] as DataTable;

                // TRY TO ADD rows with the info into the DataTable
                try
                {
                    // Add new Serial Code into DataTable dt_ShoppingBasket
                    dt_ShoppingBasket.Rows.Add(new_SerialCode.ToString());

                    // Assigns new DataTable to Session["Shopping_Basket"]
                    context.Session["Shopping_Basket"] = dt_ShoppingBasket;
                }
                catch (Exception)
                {

                    dt_ShoppingBasket.Rows.Add(new_SerialCode.ToString());

                    // Assigns new DataTable to Session["Shopping_Basket"]
                    context.Session["Shopping_Basket"] = dt_PanierCommande;
                }



                // PRINT TESTS
                DataTable dt_To_Print = context.Session["Shopping_Basket"] as DataTable;

                foreach (DataRow row in dt_To_Print.Rows)
                {
                    foreach (var item in row.ItemArray)
                    {
                        Debug.WriteLine("DATATABLE IN SESSION: " + item);
                    }
                }

$protocol = strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,5))=='https'?'https':'http';

$protocol = isset($_SERVER["HTTPS"]) ? 'https' : 'http';

These should both work

I don't think your problem is with the BouncyCastle keystore; I think the problem is with a broken javax.net.ssl package in Android. The BouncyCastle keystore is a supreme annoyance because Android changed a default Java behavior without documenting it anywhere -- and removed the default provider -- but it does work.

Note that for SSL authentication you may require 2 keystores. The "TrustManager" keystore, which contains the CA certs, and the "KeyManager" keystore, which contains your client-site public/private keys. (The documentation is somewhat vague on what needs to be in the KeyManager keystore.) In theory, you shouldn't need the TrustManager keystore if all of your certficates are signed by "well-known" Certifcate Authorities, e.g., Verisign, Thawte, and so on. Let me know how that works for you. Your server will also require the CA for whatever was used to sign your client.

I could not create an SSL connection using javax.net.ssl at all. I disabled the client SSL authentication on the server side, and I still could not create the connection. Since my end goal was an HTTPS GET, I punted and tried using the Apache HTTP Client that's bundled with Android. That sort-of worked. I could make the HTTPS conection, but I still could not use SSL auth. If I enabled the client SSL authentication on my server, the connection would fail. I haven't checked the Apache HTTP Client code, but I suspect they are using their own SSL implementation, and don't use javax.net.ssl.

If your array contains elements of the primitive data type such as int, char, or string etc then you can user one of those methods which returns a copy of the original array such as .slice() or .map() or spread operator(thanks to ES6).

new_array = old_array.slice()

or

new_array = old_array.map((elem) => elem)

or

const new_array = new Array(...old_array);

BUT if your array contains complex elements such as objects(or arrays) or more nested objects, then, you will have to make sure that you are making a copy of all the elements from the top level to the last level else reference of the inner objects will be used and that means changing values in object_elements in new_array will still affect the old_array. You can call this method of copying at each level as making a DEEP COPY of the old_array.

For deep copying, you can use the above-mentioned methods for primitive data types at each level depending upon the type of data or you can use this costly method(mentioned below) for making a deep copy without doing much work.

var new_array = JSON.parse(JSON.stringify(old_array));

There are a lot of other methods out there which you can use depending on your requirements. I have mentioned only some of those for giving a general idea of what happens when we try to copy an array into the other by value.

For Windows, here's a link to an example batch file that only allows changes to the log message (not other properties):

http://ayria.livejournal.com/33438.html

Basically copy the code below into a text file and name it pre-revprop-change.bat and save it in the \hooks subdirectory for your repository.

@ECHO OFF
:: Set all parameters. Even though most are not used, in case you want to add
:: changes that allow, for example, editing of the author or addition of log messages.
set repository=%1
set revision=%2
set userName=%3
set propertyName=%4
set action=%5

:: Only allow the log message to be changed, but not author, etc.
if /I not "%propertyName%" == "svn:log" goto ERROR_PROPNAME

:: Only allow modification of a log message, not addition or deletion.
if /I not "%action%" == "M" goto ERROR_ACTION

:: Make sure that the new svn:log message is not empty.
set bIsEmpty=true
for /f "tokens=*" %%g in ('find /V ""') do (
set bIsEmpty=false
)
if "%bIsEmpty%" == "true" goto ERROR_EMPTY

goto :eof

:ERROR_EMPTY
echo Empty svn:log messages are not allowed. >&2
goto ERROR_EXIT

:ERROR_PROPNAME
echo Only changes to svn:log messages are allowed. >&2
goto ERROR_EXIT

:ERROR_ACTION
echo Only modifications to svn:log revision properties are allowed. >&2
goto ERROR_EXIT

:ERROR_EXIT
exit /b 1

Late to the game, but you can do it without @string/xyz by using ?android:attr

    <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="?android:attr/versionName"
     />
    <!-- or -->
    <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="?android:attr/versionCode"
     />

In your PhP file there's going to be a variable called $_REQUEST and it contains an array with all the data send from Javascript to PhP using AJAX.

Try this: var_dump($_REQUEST); and check if you're receiving the values.

A very simple example:

SET a=Hello
SET b=World
SET c=%a% %b%!
echo %c%

The result should be:

Hello World!

I can't believe there's no BitSet solution.

A BitSet is an abstraction over a set of bits so we don't have to use boolean[] for more advanced interactions anymore, because it already contains most of the needed methods. It's also pretty fast in batch operations since it internally uses long values to store the bits and doesn't therefore check every bit separately like we do with boolean[].

BitSet myBitSet = new BitSet(10);
// fills the bitset with ten true values
myBitSet.set(0, 10);

For your particular case, I'd use cardinality():

if (myBitSet.cardinality() == myBitSet.size()) {
    // do something, there are no false bits in the bitset
}

Another alternative is using Guava:

return Booleans.contains(myArray, true);

The following will Return All Procedures in selected database

SELECT * FROM sys.procedures

Here's the code for server side firebase cloud request from C# / Asp.net.
Please note that your client side should have same topic.
e.g.

FirebaseMessaging.getInstance().subscribeToTopic("news");

public String SendNotificationFromFirebaseCloud()
{
    var result = "-1";
    var webAddr = "https://fcm.googleapis.com/fcm/send";

    var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
    httpWebRequest.ContentType = "application/json";
    httpWebRequest.Headers.Add("Authorization:key=" + YOUR_FIREBASE_SERVER_KEY);
    httpWebRequest.Method = "POST";

    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
        string json = "{\"to\": \"/topics/news\",\"data\": {\"message\": \"This is a Firebase Cloud Messaging Topic Message!\",}}";


        streamWriter.Write(json);
        streamWriter.Flush();
    }

    var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
    {
        result = streamReader.ReadToEnd();
    }

    return result;
}

Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.

Have in mind also that,

large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.

-- Announcement of YUI development being ceased

That said, below are a number of Ext JS alternatives currently available.

Leading client widget libraries

1. Blueprint is a React-based UI toolkit developed by big data analytics company Palantir in TypeScript, and "optimized for building complex data-dense interfaces for desktop applications". Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.

   Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

   Sandbox / demo • GitHub • Docs

2. Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.

   

   Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.

   Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.

   The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).

   The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.

   Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

3. react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.

4. kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).

   

   Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.

   A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

   [Wikipedia] • GitHub/Telerik • Demos • Playground • Tools

5. OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.

   

   The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.

   The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.

   Wikipedia • GitHub • Mobile-first controls demos • Desktop controls demos • SO

6. DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.

   

   Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.

7. Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.

   

8. Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).

   The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.

9. PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.

10. qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).

    Mobile themes look modern but desktop themes look old (gradients).

11. jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.

12. angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).

13. DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.

    

    Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.

    Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.

    With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.

14. Enyo - front-end library aimed at mobile and TV apps (e.g. large touch-friendly controls). Developed by LG Electronix and Apache-licensed on GitHub.

15. The radical Cappuccino - Objective-J (a superset of JavaScript) instead of HTML+CSS+DOM

16. Mochaui, MooTools UI Library User Interface Library. <300 GitHub stars.

17. CrossUI - cross-browser JS framework to develop and package the exactly same code and UI into Web Apps, Native Desktop Apps (Windows, OS X, Linux) and Mobile Apps (iOS, Android, Windows Phone, BlackBerry). Open sourced LGPL3. Featured RAD tool (form builder etc.). The UI looks desktop-, not web-oriented. Actively developed, small community. No presence on GitHub.

18. ZinoUI - simple widgets. The DataTable, for instance, doesn't even support sorting.

19. Wijmo - good-looking commercial widgets, with old (jQuery UI) widgets open-sourced on GitHub (their development stopped in 2013). Developed by ComponentOne, a division of GrapeCity. See Wijmo Complete vs. Open.

20. CxJS - commercial JS framework based on React, Babel and webpack offering form elements, form validation, advanced grid control, navigational elements, tooltips, overlays, charts, routing, layout support, themes, culture dependent formatting and more.

Widgets - Demo Apps - Examples - GitHub

Full-stack frameworks

1. SproutCore - developed by Apple for web applications with native performance, handling large data sets on the client. Powers iCloud.com. Not intended for widgets.

2. Wakanda: aimed at business/enterprise web apps - see What is Wakanda?. Architecture:

   • Wakanda Server (server-side JavaScript (custom engine) + open-source NoSQL database)
   • desktop IDE and WYSIWYG editor for tables, forms, reports

   • Wakanda Application Framework (datasource layer + browser-based interface widgets) that helps with browser and device compatibility across desktop and mobile

     Wakanda is highly integrated, includes a ton of features out of the box, but has a very small GitHub community and SO presence.

3. Servoy - "a cross platform frontend development and deployment environment for SQL databases". Boasts a "full WYSIWIG (What You See Is What You Get) UI designer for HTML5 with built-in data-binding to back-end services", responsive design, support for HTML6 Web Components, Websockets and mobile platforms. Written in Java and generates JavaScript code using various JavaBeans.

4. SmartClient/SmartGWT - mobile and cross-browser HTML5 UI components combined with a Java server. Aimed at building powerful business apps - see demos.

5. Vaadin - full-stack Java/GWT + JavaScript/HTML3 web app framework

6. Backbase - portal software

7. Shiny - front-end library on top R, with visualization, layout and control widgets

8. ZKOSS: Java+jQuery+Bootstrap framework for building enterprise web and mobile apps.

CSS libraries + minimal widgets

These libraries don't implement complex widgets such as tables with sorting/filtering, autocompletes, or trees.

1. Bootstrap

2. Foundation for Apps - responsive front-end framework on top of AngularJS; more of a grid/layout/navigation library

3. UI Kit - similar to Bootstrap, with fewer widgets, but with official off-canvas.

Libraries using HTML Canvas

Using the canvas elements allows for complete control over the UI, and great cross-browser compatibility, but comes at the cost of missing native browser functionality, e.g. page search via Ctrl/Cmd+F.

1. Zebra - demos

No longer developed as of Dec 2014

1. Yahoo! User Interface - YUI, launched in 2005, but no longer maintained by the core contributors - see the announcement, which highlights reasons why large UI widget libraries are perceived as walled gardens that developers don't want to be locked into.
2. echo3, GitHub. Supports writing either server-side Java applications that don't require developer knowledge of HTML, HTTP, or JavaScript, or client-side JavaScript-based applications do not require a server, but can communicate with one via AJAX. Last update: July 2013.

I think that your taxonomy is incorrect. There are two opposite types imperative and declarative. Functional is just a subtype of declarative. BTW, wikipedia states the same fact.

There is an function, but it's extra: http://docs.jquery.com/Cookbook/wait

This little snippet allows you to wait:

$.fn.wait = function(time, type) {
    time = time || 1000;
    type = type || "fx";
    return this.queue(type, function() {
        var self = this;
        setTimeout(function() {
            $(self).dequeue();
        }, time);
    });
};

echo test > afile.txt

redirects stdout to afile.txt. This is the same as doing

echo test 1> afile.txt

To redirect stderr, you do:

echo test 2> afile.txt

>& is the syntax to redirect a stream to another file descriptor - 0 is stdin, 1 is stdout, and 2 is stderr.

You can redirect stdout to stderr by doing:

echo test 1>&2 # or echo test >&2

Or vice versa:

echo test 2>&1

So, in short... 2> redirects stderr to an (unspecified) file, appending &1 redirects stderr to stdout.

In the POSIX standard clock has its return value defined in terms of the CLOCKS_PER_SEC symbol and an implementation is free to define this in any convenient fashion. Under Linux, I have had good luck with the times() function.

chmod u+x program_name. Then execute it.

If that does not work, copy the program from the USB device to a native volume on the system. Then chmod u+x program_name on the local copy and execute that.

Unix and Unix-like systems generally will not execute a program unless it is marked with permission to execute. The way you copied the file from one system to another (or mounted an external volume) may have turned off execute permission (as a safety feature). The command chmod u+x name adds permission for the user that owns the file to execute it.

That command only changes the permissions associated with the file; it does not change the security controls associated with the entire volume. If it is security controls on the volume that are interfering with execution (for example, a noexec option may be specified for a volume in the Unix fstab file, which says not to allow execute permission for files on the volume), then you can remount the volume with options to allow execution. However, copying the file to a local volume may be a quicker and easier solution.

Update to latest wkhtmltopdf version from SourceForge (0.12 as of this writing). It does not need an X Server to run.

Not sure if this completely helps, but I had an issue where I needed a "smart" merge. I had two columns, A & B. I wanted to move B over only if A was blank. See below. It is based on a selection Range, which you could use to offset the first row, perhaps.

Private Sub MergeProjectNameColumns()
    Dim rngRowCount As Integer
    Dim i As Integer

    'Loop through column C and simply copy the text over to B if it is not blank
    rngRowCount = Range(dataRange).Rows.Count
    ActiveCell.Offset(0, 0).Select
    ActiveCell.Offset(0, 2).Select
    For i = 1 To rngRowCount
        If (Len(RTrim(ActiveCell.Value)) > 0) Then
            Dim currentValue As String
            currentValue = ActiveCell.Value
            ActiveCell.Offset(0, -1) = currentValue
        End If
        ActiveCell.Offset(1, 0).Select
    Next i

    'Now delete the unused column
    Columns("C").Select

    selection.Delete Shift:=xlToLeft
End Sub

import datetime
a = datetime.datetime.today().year

or even (as Lennart suggested)

a = datetime.datetime.now().year

or even

a = datetime.date.today().year

If you are using numpy you can use np.argsort to get the sorted indices and apply those indices to the list. This works for any number of list that you would want to sort.

import numpy as np

arr1 = np.array([4,3,1,32,21])
arr2 = arr1 * 10
sorted_idxs = np.argsort(arr1)

print(sorted_idxs)
>>> array([2, 1, 0, 4, 3])

print(arr1[sorted_idxs])
>>> array([ 1,  3,  4, 21, 32])

print(arr2[sorted_idxs])
>>> array([ 10,  30,  40, 210, 320])

Just come across this, the answer is simple, use ISNULL. SQL won't return rows if the field you are testing has no value (in some of the records) when doing a text comparison search, eg:

WHERE wpp.comment NOT LIKE '%CORE%'

So, you have temporarily substitute a value in the null (empty) records by using the ISNULL command, eg

WHERE (ISNULL(wpp.comment,'')) NOT LIKE '%CORE%'

This will then show all your records that have nulls and omit any that have your matching criteria. If you wanted, you could put something in the commas to help you remember, eg

WHERE (ISNULL(wpp.comment,'some_records_have_no_value')) NOT LIKE '%CORE%'

Using Array's reduce and findIndex methods, this can be achieved.

var myArray = [{_x000D_
  group: "one",_x000D_
  color: "red"_x000D_
}, {_x000D_
  group: "two",_x000D_
  color: "blue"_x000D_
}, {_x000D_
  group: "one",_x000D_
  color: "green"_x000D_
}, {_x000D_
  group: "one",_x000D_
  color: "black"_x000D_
}];_x000D_
_x000D_
var transformedArray = myArray.reduce((acc, arr) => {_x000D_
  var index = acc.findIndex(function(element) {_x000D_
    return element.group === arr.group;_x000D_
  });_x000D_
  if (index === -1) {_x000D_
    return acc.push({_x000D_
      group: arr.group,_x000D_
      color: [arr.color]_x000D_
    });_x000D_
  }_x000D_
  _x000D_
  acc[index].color.push(arr.color);_x000D_
  return acc;_x000D_
}, []);_x000D_
_x000D_
console.log(transformedArray);

By using reduce function, array is iterator and the new values are stored in acc (accumulating) parameter. To check if the object with given group already exists we can use findIndex function.

If findIndex() return -1, the value does not exist, so add the array in the acc parameter.

If findIndex() return index, then update the index with the arr values.

Underscore-java library contains methods push(values), pop(), shift() and unshift(values).

Code example:

import com.github.underscore.U:

List<String> strings = Arrays.asList("one", "two", " three");
List<String> newStrings = U.push(strings, "four", "five");
// ["one", " two", "three", " four", "five"]
String newPopString = U.pop(strings).fst();
// " three"
String newShiftString = U.shift(strings).fst();
// "one"
List<String> newUnshiftStrings = U.unshift(strings, "four", "five");
// ["four", " five", "one", " two", "three"]

From the documentation for sys.exit:

The optional argument arg can be an integer giving the exit status (defaulting to zero), or another type of object. If it is an integer, zero is considered “successful termination” and any nonzero value is considered “abnormal termination” by shells and the like. Most systems require it to be in the range 0-127, and produce undefined results otherwise. Some systems have a convention for assigning specific meanings to specific exit codes, but these are generally underdeveloped; Unix programs generally use 2 for command line syntax errors and 1 for all other kind of errors.

One example where exit codes are used are in shell scripts. In Bash you can check the special variable $? for the last exit status:

me@mini:~$ python -c ""; echo $?
0
me@mini:~$ python -c "import sys; sys.exit(0)"; echo $?
0
me@mini:~$ python -c "import sys; sys.exit(43)"; echo $?
43

Personally I try to use the exit codes I find in /usr/include/asm-generic/errno.h (on a Linux system), but I don't know if this is the right thing to do.

You'll have problems creating lists without commas. It shouldn't be too hard to transform your data so that it uses commas as separating character.

Once you have commas in there, it's a relatively simple list creation operations:

array1 = [1,2,3]
array2 = [4,5,6]

array3 = [array1, array2]

array4 = [7,8,9]
array5 = [10,11,12]

array3 = [array3, [array4, array5]]

When testing we get:

print(array3)

[[[1, 2, 3], [4, 5, 6]], [[7, 8, 9], [10, 11, 12]]]

And if we test with indexing it works correctly reading the matrix as made up of 2 rows and 2 columns:

array3[0][1]
[4, 5, 6]

array3[1][1]
[10, 11, 12]

Hope that helps.

For an organization or a business, there are so many physical entities (such as people, resources, machines, etc.) and virtual entities (their Tasks, transactions, activities). Typically, business needs to record and process information of those business entities. These business entities are identified within a whole business domain by a Key.

As per RDBMS prospective, Key (a.k.a Candidate Key) is a value or set of values that uniquely identifies an entity.

For a DB-Table, there are so many keys are exist and might be eligible for Primary Key. So that all keys, primary key, unique key, etc are collectively called as Candidate Key. However, DBA selected a key from candidate key for searching records is called Primary key.

Difference between Primary Key and Unique key

1. Behavior: Primary Key is used to identify a row (record) in a table, whereas Unique-key is to prevent duplicate values in a column (with the exception of a null entry).

2. Indexing: By default SQL-engine creates Clustered Index on primary-key if not exists and Non-Clustered Index on Unique-key.

3. Nullability: Primary key does not include Null values, whereas Unique-key can.

4. Existence: A table can have at most one primary key, but can have multiple Unique-key.

5. Modifiability: You can’t change or delete primary values, but Unique-key values can.

For more information and Examples:

http://dotnetauthorities.blogspot.in/2013/11/Microsoft-SQL-Server-Training-Online-Learning-Classes-Integrity-Constraints-PrimaryKey-Unique-Key_27.html

new table inherits only "not null" constraint and no other constraint. Thus you can alter the table after creating it with "create table as" command or you can define all constraint that you need by following the

create table t1 (id number default 1 not null);
insert into t1 (id) values (2);

create table t2 as select * from t1;

This will create table t2 with not null constraint. But for some other constraint except "not null" you should use the following syntax

create table t1 (id number default 1 unique);
insert into t1 (id) values (2);

create table t2 (id default 1 unique)
as select * from t1;

The future is here! The proposals are closer to completion, no more ActiveX or flash or java. Now we can use:

• File System APIs

• Native Drag&Drop File Access

You could use the Drag/Drop to get the file into the browser, or a simple upload control. Once the user has selected a file, you can read it w/ Javascript: http://www.html5rocks.com/en/tutorials/file/dndfiles/

You can use:

PyXML:

from xml.dom.ext.reader import Sax2
from xml import xpath
doc = Sax2.FromXmlFile('foo.xml').documentElement
for url in xpath.Evaluate('//@Url', doc):
  print url.value

libxml2:

import libxml2
doc = libxml2.parseFile('foo.xml')
for url in doc.xpathEval('//@Url'):
  print url.content

Simply mark any method you need to fake as virtual (and not private). Then you will be able to create a fake that can override the method.

If you use new Mock<Type> and you don't have a parameterless constructor then you can pass the parameters as the arguments of the above call as it takes a type of param Objects

I use command:

openssl x509 -inform PEM -in certificate.cer -out certificate.crt

But CER is an X.509 certificate in binary form, DER encoded. CRT is a binary X.509 certificate, encapsulated in text (base-64) encoding.

Because of that, you maybe should use:

openssl x509 -inform DER -in certificate.cer -out certificate.crt

And then to import your certificate:

Copy your CA to dir:

/usr/local/share/ca-certificates/

Use command:

sudo cp foo.crt /usr/local/share/ca-certificates/foo.crt

Update the CA store:

sudo update-ca-certificates

@SafeVarargs does not prevent it from happening, however it mandates that the compiler is stricter when compiling code that uses it.

Heap pollution is when you get a ClassCastException when doing an operation on a generic interface and it contains another type than declared.

This answer has not been given yet so I thought I'd post it. I looked all around the web, and didn't find a good answer for testing favicons in local development.

In current version of chrome (on OSX) if you do the following you will get an instant favicon refresh:

1. Hover over tab
2. Right Click
3. Select reload
4. Your favicon should now be refreshed

This is the easiest way I've found to refresh the favicon locally.

@SimonBuchan is correct.

Since git 1.8.2, Resources/** !Resources/**/*.foo works.

There are probably tests you can do, for instance if you know that the JSON returned is always going to be surrounded by { and } then you could test for those characters, or some other hacky method. Or you could use the json.org JS library to try and parse it and test if it succeeds.

I would however suggest a different approach. Your PHP script currently returns JSON if the call is successful, but something else if it is not. Why not always return JSON?

E.g.

Successful call:

{ "status": "success", "data": [ <your data here> ] }

Erroneous call:

{ "status": "error", "error": "Database not found" }

This would make writing your client side JS much easier - all you have to do is check the "status" member and the act accordingly.

But you can open the folder with the .SLN in to edit the code in the project, which will detect the .SLN to select the library that provides Intellisense.

Do you have installed the android plugin ?

Your project must be of the android type.

import datetime
datetime.datetime.strptime('24052010', '%d%m%Y').date()

I couldn't solve my problem using provided answers. Finally I changed this:

<fragment
android:id="@+id/fragment_food_image_gallery"
android:name="ir.smartrestaurant.ui.fragment.ImageGalleryFragment"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout="@layout/fragment_image_gallery"
tools:layout="@layout/fragment_image_gallery" />

to this :

<FrameLayout
android:id="@+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="200dp" />

,

private void showGallery() {
    ImageGalleryFragment fragment = new ImageGalleryFragment()
    getSupportFragmentManager().beginTransaction()
                .replace(R.id.fragment_container, fragment)
                .commit();
    }

and it works.
If you are using it inside fragment, use getChildFragmentManager instead of getSupportFragmentManager.

I was facing the same issue; and the following worked well for me. Hope this helps someone landing here:

<div class="row">
  <div class="col-md-6">
    <div class="col-md-12">
     Set room heater temperature
   </div>
 </div>
 <div class="col-md-6">
   <div class="col-md-12">
     Set room heater temperature
   </div>
 </div>
</div>

This will automatically render some space between the 2 divs.

For me this solution worked well to center an input field in a TD:

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha/css/bootstrap.css" rel="stylesheet" />_x000D_
<td style="background:#B3AEB5;">_x000D_
  <div class="form-group text-center">_x000D_
    <div class="input-group" style="margin:auto;">_x000D_
      <input type="month" name="p2" value="test">_x000D_
    </div>_x000D_
  </div>_x000D_
</td>

var userPasswordString = new Buffer(baseAuth, 'base64').toString('ascii');

Change this line from your code to this -

var userPasswordString = Buffer.from(baseAuth, 'base64').toString('ascii');

or in my case, I gave the encoding in reverse order

var userPasswordString = Buffer.from(baseAuth, 'utf-8').toString('base64');

There is element.classList in the DOM API that works for both HTML and SVG elements. No need for jQuery SVG plugin or even jQuery.

$(".jimmy").click(function() {
    this.classList.add("clicked");
});

Often, you don't need any auto* tools and the simplest solution is to simply run touch aclocal.m4 configure in the relevant folder (and also run touch on Makefile.am and Makefile.in if they exist). This will update the timestamp of aclocal.m4 and remind the system that aclocal.m4 is up-to-date and doesn't need to be rebuilt. After this, it's probably best to empty your build directory and rerun configure from scratch after doing this. I run into this problem regularly. For me, the root cause is that I copy a library (e.g. mpfr code for gcc) from another folder and the timestamps change.

Of course, this trick isn't valid if you really do need to regenerate those files, perhaps because you have manually changed them. But hopefully the developers of the package distribute up-to-date files.

And of course, if you do want to install automake and friends, then use the appropriate package-manager for your distribution.

Install aclocal which comes with automake:

brew install automake          # for Mac
apt-get install automake       # for Ubuntu

Try again:

./configure && make

• Cheat Sheet
• Quick Reference

Implementations

Although the reference implementation of reStructuredText is written in Python, there are reStructuredText parsers in other languages too.

Python - Docutils

The main distribution of reStructuredText is the Python Docutils package. It contains several conversion tools:

• rst2html - from reStructuredText to HTML
• rst2xml - from reStructuredText to XML
• rst2latex - from reStructuredText to LaTeX
• rst2odt - from reStructuredText to ODF Text (word processor) document.
• rst2s5 - from reStructuredText to S5, a Simple Standards-based Slide Show System
• rst2man - from reStructuredText to Man page

Haskell - Pandoc

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read Markdown and (subsets of) reStructuredText, HTML, and LaTeX, and it can write Markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, and S5 HTML slide shows.

There is an Pandoc online tool (POT) to try this library. Unfortunately, compared to the reStructuredText online renderer (ROR),

• POT truncates input rather more shortly. The POT user must render input in chunks that could be rendered whole by the ROR.
• POT output lacks the helpful error messages displayed by the ROR (and generated by docutils)

Java - JRst

JRst is a Java reStructuredText parser. It can currently output HTML, XHTML, DocBook xdoc and PDF, BUT seems to have serious problems: neither PDF or (X)HTML generation works using the current full download, result pages in (X)HTML are empty and PDF generation fails on IO problems with XSL files (not bundled??). Note that the original JRst has been removed from the website; a fork is found on GitHub.

Scala - Laika

Laika is a new library for transforming markup languages to other output formats. Currently it supports input from Markdown and reStructuredText and produce HTML output. The library is written in Scala but should be also usable from Java.

Perl

• Text::Restructured - Perl implementation of reStructuredText parser
• Dotiac::DTL::Addon::markup - Filters to work with common markup languages - support reStructuredText
• Pod::POM::View::Restructured - View for Pod::POM that outputs reStructuredText

PHP

• Gregwar/RST - A mature PHP5.3 parser with tests
• php-restructuredtext - A simple, incomplete (but functional) implementation

C#/.NET

• reStructuredText for ANTLR - A C# based parser with tests (in progress). It also provides the language server behind reStructuredText extension for Visual Studio Code.

Nim/C

The Nim compiler features the commands rst2htmland rst2tex which transform reStructuredText files to HTML and TeX files. The standard library provides the following modules (used by the compiler) to handle reStructuredText files programmatically:

• rst - implements a reStructuredText parser
• rstast - implements an AST for the reStructuredText parser
• rstgen - implements a generator of HTML/Latex from reStructuredText

Other 3rd party converters

Most (but not all) of these tools are based on Docutils (see above) and provide conversion to or from formats that might not be supported by the main distribution.

From reStructuredText

• restview - This pip-installable python package requires docutils, which does the actual rendering. restview's major ease-of-use feature is that, when you save changes to your document(s), it automagically re-renders and re-displays them. restview
  1. starts a small web server
  2. calls docutils to render your document(s) to HTML
  3. calls your device's browser to display the output HTML.
• rst2pdf - from reStructuredText to PDF
• rst2odp - from reStructuredText to ODF Presentation
• rst2beamer - from reStructuredText to LaTeX beamer Presentation class
• Wikir - from reStructuredText to a Google (and possibly other) Wiki formats
• rst2qhc - Convert a collection of reStructuredText files into a Qt (toolkit) Help file and (optional) a Qt Help Project file

To reStructuredText

• xml2rst is an XSLT script to convert Docutils internal XML representation (back) to reStructuredText
• Pandoc (see above) can also convert from Markdown, HTML and LaTeX to reStructuredText
• db2rst is a simple and limited DocBook to reStructuredText translator
• pod2rst - convert .pod files to reStructuredText files

Extensions

Some projects use reStructuredText as a baseline to build on, or provide extra functionality extending the utility of the reStructuredText tools.

Sphinx

The Sphinx documentation generator translates a set of reStructuredText source files into various output formats, automatically producing cross-references, indices etc.

rest2web

rest2web is a simple tool that lets you build your website from a single template (or as many as you want), and keep the contents in reStructuredText.

Pygments

Pygments is a generic syntax highlighter for general use in all kinds of software such as forum systems, Wikis or other applications that need to prettify source code. See Using Pygments in reStructuredText documents.

Free Editors

While any plain text editor is suitable to write reStructuredText documents, some editors have better support than others.

Emacs

The Emacs support via rst-mode comes as part of the Docutils package under /docutils/tools/editors/emacs/rst.el

Vim

The vim-common package for that comes with most GNU/Linux distributions has reStructuredText syntax highlight and indentation support of reStructuredText out of the box:

• reStructuredText syntax highlighting mode for vim
• VST (Vim reStructured Text) is a plugin for Vim7 with folding for reStructuredText
• Riv.vim - fresh vim plugin for authoring rst and Sphinx doc
• Previm: Vim plugin for live previewing of reStructuredText and other mark up documents

Jed

There is a rst mode for the Jed programmers editor.

gedit

gedit, the official text editor of the GNOME desktop environment. There is a gedit reStructuredText plugin.

Geany

Geany, a small and lightweight Integrated Development Environment include support for reStructuredText from version 0.12 (October 10, 2007).

Leo

Leo, an outlining editor for programmers, supports reStructuredText via rst-plugin or via "@auto-rst" nodes (it's not well-documented, but @auto-rst nodes allow editing rst files directly, parsing the structure into the Leo outline).

It also provides a way to preview the resulting HTML, in a "viewrendered" pane.

FTE

The FTE Folding Text Editor - a free (licensed under the GNU GPL) text editor for developers. FTE has a mode for reStructuredText support. It provides color highlighting of basic RSTX elements and special menu that provide easy way to insert most popular RSTX elements to a document.

PyK

PyK is a successor of PyEdit and reStInPeace, written in Python with the help of the Qt4 toolkit.

Eclipse

The Eclipse IDE with the ReST Editor plug-in provides support for editing reStructuredText files.

NoTex

NoTex is a browser based (general purpose) text editor, with integrated project management and syntax highlighting. Plus it enables to write books, reports, articles etc. using rST and convert them to LaTex, PDF or HTML. The PDF files are of high publication quality and are produced via Sphinx with the Texlive LaTex suite.

Notepad++

Notepad++ is a general purpose text editor for Windows. It has syntax highlighting for many languages built-in and support for reStructuredText via a user defined language for reStructuredText.

Visual Studio Code

Visual Studio Code is a general purpose text editor for Windows/macOS/Linux. It has syntax highlighting for many languages built-in and supports reStructuredText via an extension from LeXtudio.

Dedicated reStructuredText Editors

• ReSTedit by Dinu Gherman and Bill Bumgarner
• Rest in Peace
• Enthought Tool Suite editor
• ReText a cross platform program that works like Marked.
• RSTPad a standalone cross-platform editor with live preview

Proprietary editors

Sublime Text

Sublime Text is a completely customizable and extensible source code editor available for Windows, OS X, and Linux. Registration is required for long-term use, but all functions are available in the unregistered version, with occasional reminders to purchase a license. Versions 2 and 3 (currently in beta) support reStructuredText syntax highlighting by default, and several plugins are available through the package manager Package Control to provide snippets and code completion, additional syntax highlighting, conversion to/from RST and other formats, and HTML preview in the browser.

BBEdit / TextWrangler

BBEdit (and its free variant TextWrangler) for Mac can syntax-highlight reStructuredText using this codeless language module.

TextMate

Wiki

here are some Wiki programs that support the reStructuredText markup as the native markup syntax, or as an add-on:

MediaWiki

MediaWiki reStructuredText extension allows for reStructuredText markup in MediaWiki surrounded by <rst> and </rst>.

MoinMoin

MoinMoin is an advanced, easy to use and extensible WikiEngine with a large community of users. Said in a few words, it is about collaboration on easily editable web pages.

There is a reStructuredText Parser for MoinMoin.

Trac

Trac is an enhanced wiki and issue tracking system for software development projects. There is a reStructuredText Support in Trac.

This Wiki

This Wiki is a Webware for Python Wiki written by Ian Bicking. This wiki uses ReStructuredText for its markup.

rstiki

rstiki is a minimalist single-file personal wiki using reStructuredText syntax (via docutils) inspired by pwyky. It does not support authorship indication, versioning, hierarchy, chrome/framing/templating or styling. It leverages docutils/reStructuredText as the wiki syntax. As such, it's under 200 lines of code, and in a single file. You put it in a directory and it runs.

ikiwiki

Ikiwiki is a wiki compiler. It converts wiki pages into HTML pages suitable for publishing on a website. Ikiwiki stores pages and history in a revision control system such as Subversion or Git. There are many other features, including support for blogging, as well as a large array of plugins. It's reStructuredText plugin, however is somewhat limited and is not recommended as its' main markup language at this time.

Web Services

Sandbox

An Online reStructuredText editor can be used to play with the markup and see the results immediately.

I know this has already been highly voted in here by now, but I'd rather go for a custom directive approach and rely on the ClipboardEvent as @jockeisorby suggested, while also making sure the listener is correctly removed (same function needs to be provided for both the add and remove event listeners)

stackblitz demo

import { Directive, Input, Output, EventEmitter, HostListener } from "@angular/core";

@Directive({ selector: '[copy-clipboard]' })
export class CopyClipboardDirective {

  @Input("copy-clipboard")
  public payload: string;

  @Output("copied")
  public copied: EventEmitter<string> = new EventEmitter<string>();

  @HostListener("click", ["$event"])
  public onClick(event: MouseEvent): void {

    event.preventDefault();
    if (!this.payload)
      return;

    let listener = (e: ClipboardEvent) => {
      let clipboard = e.clipboardData || window["clipboardData"];
      clipboard.setData("text", this.payload.toString());
      e.preventDefault();

      this.copied.emit(this.payload);
    };

    document.addEventListener("copy", listener, false)
    document.execCommand("copy");
    document.removeEventListener("copy", listener, false);
  }
}

and then use it as such

<a role="button" [copy-clipboard]="'some stuff'" (copied)="notify($event)">
  <i class="fa fa-clipboard"></i>
  Copy
</a>

public notify(payload: string) {
   // Might want to notify the user that something has been pushed to the clipboard
   console.info(`'${payload}' has been copied to clipboard`);
}

Note: notice the window["clipboardData"] is needed for IE as it does not understand e.clipboardData

Use SpecialCells to delete only the rows that are visible after autofiltering:

ActiveSheet.Range("$A$1:$I$" & lines).SpecialCells _
    (xlCellTypeVisible).EntireRow.Delete

If you have a header row in your range that you don't want to delete, add an offset to the range to exclude it:

ActiveSheet.Range("$A$1:$I$" & lines).Offset(1, 0).SpecialCells _
    (xlCellTypeVisible).EntireRow.Delete

Run following command in git bash that works fine for me

git config --global http.sslverify "false"

tail -f /var/log/syslog | grep process_name where process_name is the name of the process we are interested in

The best way is probably to use:

:%s/phrase//gc

c asks for confirmation before each deletion. g allows multiple replacements to occur on the same line.

You can also just search using /phrase, select the next match with gn, and delete it with d.

Like Java (which is what C# was indirectly derived from), C# does not support multiple inhertance.

Which is to say that class data (member variables and properties) can only be inherited from a single parent base class. Class behavior (member methods), on the other hand, can be inherited from multiple parent base interfaces.

Some experts, notably Bertrand Meyer (considered by some to be one of the fathers of object-oreiented programming), think that this disqualifies C# (and Java, and all the rest) from being a "true" object-oriented language.

You can change the code by using class definition for the i element:

<a href="javascript:void"><i class="fa fa-plus-circle"></i>Category 1</a>

Then you can switch the classes rapresenting the plus/minus state using toggleClass with multiple classes:

$('#category-tabs li a').click(function(){
    $(this).next('ul').slideToggle('500');
    $(this).find('i').toggleClass('fa-plus-circle fa-minus-circle');
});
