A normal variable is set by simply assigning it a value; note that no whitespace is allowed around the =:

HOME=c

An environment variable is a regular variable that has been marked for export to the environment.

export HOME
HOME=c

You can combine the assignment with the export statement.

export HOME=c

Also if your working directory is different than you can use lpDirectory

    procInfo = ShellExecuteEx(nShow=showCmd,
                          lpVerb=lpVerb,
                          lpFile=cmd,
                          lpDirectory= unicode(direc),
                          lpParameters=params)

Will come handy if changing the path is not a desirable option remove unicode for python 3.X

I know this is old, but since Postgresql 9.3 there is an option to use a keyword "LATERAL" to use RELATED subqueries inside of JOINS, so the query from the question would look like:

SELECT 
    name, author_id, count(*), t.total
FROM
    names as n1
    INNER JOIN LATERAL (
        SELECT 
            count(*) as total
        FROM 
            names as n2
        WHERE 
            n2.id = n1.id
            AND n2.author_id = n1.author_id
    ) as t ON 1=1
GROUP BY 
    n1.name, n1.author_id

JPA is a specification to standardize ORM-APIs. Hibernate is a vendor of a JPA implementation. So if you use JPA with hibernate, you can use the standard JPA API, hibernate will be under the hood, offering some more non standard functions. See http://docs.jboss.org/hibernate/stable/entitymanager/reference/en/html_single/ and http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/

You need to scp something somewhere. You have scp ./styles/, so you're saying secure copy ./styles/, but not where to copy it to.

Generally, if you want to download, it will go:

# download: remote -> local
scp user@remote_host:remote_file local_file 

where local_file might actually be a directory to put the file you're copying in. To upload, it's the opposite:

# upload: local -> remote
scp local_file user@remote_host:remote_file

If you want to copy a whole directory, you will need -r. Think of scp as like cp, except you can specify a file with user@remote_host:file as well as just local files.

Edit: As noted in a comment, if the usernames on the local and remote hosts are the same, then the user can be omitted when specifying a remote file.

With the help of the given links I was able to solve the problem myself. The correct way is to get the resource ID with

getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
                             "raw", getPackageName());

To get it as a InputStream

InputStream ins = getResources().openRawResource(
            getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
            "raw", getPackageName()));

viewport meta tag on mobile browser,

The last two lines are important to align in center:

}

Sure. In this case, you'd just do:

length_key = len(d['key'])  # length of the list stored at `'key'` ...

It's hard to say why you actually want this, but, perhaps it would be useful to create another dict that maps the keys to the length of values:

length_dict = {key: len(value) for key, value in d.items()}
length_key = length_dict['key']  # length of the list stored at `'key'` ...

Here's how we were able to validate the RECAPTCHA using .NET:

FRONT-END

<div id="rcaptcha" class="g-recaptcha" data-sitekey="[YOUR-KEY-GOES-HERE]" data-callback="onFepCaptchaSubmit"></div>

BACK-END:

    public static bool IsCaptchaValid(HttpRequestBase requestBase)
    {
        var recaptchaResponse = requestBase.Form["g-recaptcha-response"];
        if (string.IsNullOrEmpty(recaptchaResponse))
        {
            return false;
        }

        string postData = string.Format("secret={0}&response={1}&remoteip={2}", "[YOUR-KEY-GOES-HERE]", recaptchaResponse, requestBase.UserHostAddress);
        byte[] data = System.Text.Encoding.ASCII.GetBytes(postData);

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.google.com/recaptcha/api/siteverify");

        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";
        request.ContentLength = data.Length;

        using (var stream = request.GetRequestStream())
        {
            stream.Write(data, 0, data.Length);
        }

        var response = (HttpWebResponse)request.GetResponse();

        var responseString = "";

        using (var sr = new System.IO.StreamReader(response.GetResponseStream()))
        {
            responseString = sr.ReadToEnd();
        }

        return System.Text.RegularExpressions.Regex.IsMatch(responseString, "\"success\"(\\s*?):(\\s*?)true", System.Text.RegularExpressions.RegexOptions.Compiled);
    }

Call the above method within your Controller's POST action.

The PropertiesPlaceholderConfigurer bean has an alternative property called "propertiesArray". Use this instead of the "properties" property, and configure it with an <array> of property references.

Another way to create an array with String apart from

String[] strings =  { "abc", "def", "hij", "xyz" };

is to use split. I find this more readable if there are lots of Strings.

String[] strings =  "abc,def,hij,xyz".split(",");

or the following is good if you are parsing lines of strings from another source.

String[] strings =  ("abc\n" +
                     "def\n" +
                     "hij\n" +
                     "xyz").split("\n");

Create a function like so:

CREATE FUNCTION dbo.fn_FileExists(@path varchar(512))
RETURNS BIT
AS
BEGIN
     DECLARE @result INT
     EXEC master.dbo.xp_fileexist @path, @result OUTPUT
     RETURN cast(@result as bit)
END;
GO

Edit your table and add a computed column (IsExists BIT). Set the expression to:

dbo.fn_FileExists(filepath)

Then just select:

SELECT * FROM dbo.MyTable where IsExists = 1

Update:

To use the function outside a computed column:

select id, filename, dbo.fn_FileExists(filename) as IsExists
from dbo.MyTable

Update:

If the function returns 0 for a known file, then there is likely a permissions issue. Make sure the SQL Server's account has sufficient permissions to access the folder and files. Read-only should be enough.

And YES, by default, the 'NETWORK SERVICE' account will not have sufficient right into most folders. Right click on the folder in question and select 'Properties', then click on the 'Security' tab. Click 'Edit' and add 'Network Service'. Click 'Apply' and retest.

I created these functions based on Joey Guerra's suggestion, thank you for that. I'm elaborating a little bit, perhaps someone can use it. The first function checkDefaults() is called when an input changes, the second is called when the form is submitted using jQuery.post. div.updatesubmit is my submit button, and class 'needsupdate' is an indicator that an update is made but not yet submitted.

function checkDefaults() {
    var changed = false;
        jQuery('input').each(function(){
            if(this.defaultValue != this.value) {
                changed = true;
            }
        });
        if(changed === true) {
            jQuery('div.updatesubmit').addClass("needsupdate");
        } else {
            jQuery('div.updatesubmit').removeClass("needsupdate");
        }
}

function renewDefaults() {
        jQuery('input').each(function(){
            this.defaultValue = this.value;
        });
        jQuery('div.updatesubmit').removeClass("needsupdate");

In SQL you may only use table type which is defined at schema level (not at package or procedure level), and index-by table (associative array) cannot be defined at schema level. So - you have to define nested table like this

create type exch_row as object (
    currency_cd VARCHAR2(9),
    exch_rt_eur NUMBER,
    exch_rt_usd NUMBER);

create type exch_tbl as table of exch_row;

And then you can use it in SQL with TABLE operator, for example:

declare
   l_row     exch_row;
   exch_rt   exch_tbl;
begin
   l_row := exch_row('PLN', 100, 100);
   exch_rt  := exch_tbl(l_row);

   for r in (select i.*
               from item i, TABLE(exch_rt) rt
              where i.currency = rt.currency_cd) loop
      -- your code here
   end loop;
end;
/

For those of you who need to convert hexadecimal representation of a signed byte from two-character String into byte (which in Java is always signed), there is an example. Parsing a hexadecimal string never gives negative number, which is faulty, because 0xFF is -1 from some point of view (two's complement coding). The principle is to parse the incoming String as int, which is larger than byte, and then wrap around negative numbers. I'm showing only bytes, so that example is short enough.

String inputTwoCharHex="FE"; //whatever your microcontroller data is

int i=Integer.parseInt(inputTwoCharHex,16);
//negative numbers is i now look like 128...255

// shortly i>=128
if (i>=Integer.parseInt("80",16)){

    //need to wrap-around negative numbers
    //we know that FF is 255 which is -1
    //and FE is 254 which is -2 and so on
    i=-1-Integer.parseInt("FF",16)+i;
    //shortly i=-256+i;
}
byte b=(byte)i;
//b is now surely between -128 and +127

This can be edited to process longer numbers. Just add more FF's or 00's respectively. For parsing 8 hex-character signed integers, you need to use Long.parseLong, because FFFF-FFFF, which is integer -1, wouldn't fit into Integer when represented as a positive number (gives 4294967295). So you need Long to store it. After conversion to negative number and casting back to Integer, it will fit. There is no 8 character hex string, that wouldn't fit integer in the end.

Update: React 16.0 introduced portals through ReactDOM.createPortal link

Update: next versions of React (Fiber: probably 16 or 17) will include a method to create portals: ReactDOM.unstable_createPortal() link

Use portals

Dan Abramov answer first part is fine, but involves a lot of boilerplate. As he said, you can also use portals. I'll expand a bit on that idea.

The advantage of a portal is that the popup and the button remain very close into the React tree, with very simple parent/child communication using props: you can easily handle async actions with portals, or let the parent customize the portal.

What is a portal?

A portal permits you to render directly inside document.body an element that is deeply nested in your React tree.

The idea is that for example you render into body the following React tree:

<div className="layout">
  <div className="outside-portal">
    <Portal>
      <div className="inside-portal">
        PortalContent
      </div>
    </Portal>
  </div>
</div>

And you get as output:

<body>
  <div class="layout">
    <div class="outside-portal">
    </div>
  </div>
  <div class="inside-portal">
    PortalContent
  </div>
</body>

The inside-portal node has been translated inside <body>, instead of its normal, deeply-nested place.

When to use a portal

A portal is particularly helpful for displaying elements that should go on top of your existing React components: popups, dropdowns, suggestions, hotspots

Why use a portal

No z-index problems anymore: a portal permits you to render to <body>. If you want to display a popup or dropdown, this is a really nice idea if you don't want to have to fight against z-index problems. The portal elements get added do document.body in mount order, which means that unless you play with z-index, the default behavior will be to stack portals on top of each others, in mounting order. In practice, it means that you can safely open a popup from inside another popup, and be sure that the 2nd popup will be displayed on top of the first, without having to even think about z-index.

In practice

Most simple: use local React state: if you think, for a simple delete confirmation popup, it's not worth to have the Redux boilerplate, then you can use a portal and it greatly simplifies your code. For such a use case, where the interaction is very local and is actually quite an implementation detail, do you really care about hot-reloading, time-traveling, action logging and all the benefits Redux brings you? Personally, I don't and use local state in this case. The code becomes as simple as:

class DeleteButton extends React.Component {
  static propTypes = {
    onDelete: PropTypes.func.isRequired,
  };

  state = { confirmationPopup: false };

  open = () => {
    this.setState({ confirmationPopup: true });
  };

  close = () => {
    this.setState({ confirmationPopup: false });
  };

  render() {
    return (
      <div className="delete-button">
        <div onClick={() => this.open()}>Delete</div>
        {this.state.confirmationPopup && (
          <Portal>
            <DeleteConfirmationPopup
              onCancel={() => this.close()}
              onConfirm={() => {
                this.close();
                this.props.onDelete();
              }}
            />
          </Portal>
        )}
      </div>
    );
  }
}

Simple: you can still use Redux state: if you really want to, you can still use connect to choose whether or not the DeleteConfirmationPopup is shown or not. As the portal remains deeply nested in your React tree, it is very simple to customize the behavior of this portal because your parent can pass props to the portal. If you don't use portals, you usually have to render your popups at the top of your React tree for z-index reasons, and usually have to think about things like "how do I customize the generic DeleteConfirmationPopup I built according to the use case". And usually you'll find quite hacky solutions to this problem, like dispatching an action that contains nested confirm/cancel actions, a translation bundle key, or even worse, a render function (or something else unserializable). You don't have to do that with portals, and can just pass regular props, since DeleteConfirmationPopup is just a child of the DeleteButton

Conclusion

Portals are very useful to simplify your code. I couldn't do without them anymore.

Note that portal implementations can also help you with other useful features like:

• Accessibility
• Espace shortcuts to close the portal
• Handle outside click (close portal or not)
• Handle link click (close portal or not)
• React Context made available in portal tree

react-portal or react-modal are nice for popups, modals, and overlays that should be full-screen, generally centered in the middle of the screen.

react-tether is unknown to most React developers, yet it's one of the most useful tools you can find out there. Tether permits you to create portals, but will position automatically the portal, relative to a given target. This is perfect for tooltips, dropdowns, hotspots, helpboxes... If you have ever had any problem with position absolute/relative and z-index, or your dropdown going outside of your viewport, Tether will solve all that for you.

You can, for example, easily implement onboarding hotspots, that expands to a tooltip once clicked:

Real production code here. Can't be any simpler :)

<MenuHotspots.contacts>
  <ContactButton/>
</MenuHotspots.contacts>

Edit: just discovered react-gateway which permits to render portals into the node of your choice (not necessarily body)

Edit: it seems react-popper can be a decent alternative to react-tether. PopperJS is a library that only computes an appropriate position for an element, without touching the DOM directly, letting the user choose where and when he wants to put the DOM node, while Tether appends directly to the body.

Edit: there's also react-slot-fill which is interesting and can help solve similar problems by allowing to render an element to a reserved element slot that you put anywhere you want in your tree

Changing PHP version from 5.6 to 5.5 Fixed it.

You have to go to control panel > CGI Script and change PHP version there.

Other solutions mix regex syntaxes. To use perl/PCRE patterns for both search and replace, and only process matching files, this works quite well:

grep -rlIZPi 'match1' | xargs -0r perl -pi -e 's/match2/replace/gi;'

match1 and match2 are usually identical but match1 can be simplified to remove more advanced features that are only relevant to the substitution, e.g. capturing groups.

Translation: grep recursively and list matching filenames, each separated by nul to protect any special characters; pipe any filenames to xargs which is expecting a nul-separated list; if any filenames are received, pass them to perl to perform the actual substitutions.

For case-sensitive matching, drop the i flag from grep and the i pattern modifier from the s/// expression, but not the i flag from perl itself. Remove the I flag from grep to include binary files.

Ordinary javascript cannot close windows willy-nilly. This is a security feature, introduced a while ago, to stop various malicious exploits and annoyances.

From the latest working spec for window.close():

The close() method on Window objects should, if all the following conditions are met, close the browsing context A:

• The corresponding browsing context A is script-closable.
• The browsing context of the incumbent script is familiar with the browsing context A.
• The browsing context of the incumbent script is allowed to navigate the browsing context A.

A browsing context is script-closable if it is an auxiliary browsing context that was created by a script (as opposed to by an action of the user), or if it is a browsing context whose session history contains only one Document.

This means, with one small exception, javascript must not be allowed to close a window that was not opened by that same javascript.

Chrome allows that exception -- which it doesn't apply to userscripts -- however Firefox does not. The Firefox implementation flat out states:

This method is only allowed to be called for windows that were opened by a script using the window.open method.

If you try to use window.close from a Greasemonkey / Tampermonkey / userscript you will get:
Firefox: The error message, "Scripts may not close windows that were not opened by script."
Chrome: just silently fails.

The long-term solution:

The best way to deal with this is to make a Chrome extension and/or Firefox add-on instead. These can reliably close the current window.

However, since the security risks, posed by window.close, are much less for a Greasemonkey/Tampermonkey script; Greasemonkey and Tampermonkey could reasonably provide this functionality in their API (essentially packaging the extension work for you).
Consider making a feature request.

The hacky workarounds:

Chrome is currently was vulnerable to the "self redirection" exploit. So code like this used to work in general:

open(location, '_self').close();

This is buggy behavior, IMO, and is now (as of roughly April 2015) mostly blocked. It will still work from injected code only if the tab is freshly opened and has no pages in the browsing history. So it's only useful in a very small set of circumstances.

However, a variation still works on Chrome (v43 & v44) plus Tampermonkey (v3.11 or later). Use an explicit @grant and plain window.close(). EG:

// ==UserScript==
// @name        window.close demo
// @include     http://YOUR_SERVER.COM/YOUR_PATH/*
// @grant       GM_addStyle
// ==/UserScript==

setTimeout (window.close, 5000);

Thanks to zanetu for the update. Note that this will not work if there is only one tab open. It only closes additional tabs.

Firefox is secure against that exploit. So, the only javascript way is to cripple the security settings, one browser at a time.

You can open up about:config and set
allow_scripts_to_close_windows to true.

If your script is for personal use, go ahead and do that. If you ask anyone else to turn that setting on, they would be smart, and justified, to decline with prejudice.

There currently is no equivalent setting for Chrome.

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

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

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

print(text)

Output: \x02-\xdfI

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

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

var ret = "data-123".replace('data-','');_x000D_
console.log(ret);   //prints: 123

Docs.

For all occurrences to be discarded use:

var ret = "data-123".replace(/data-/g,'');

PS: The replace function returns a new string and leaves the original string unchanged, so use the function return value after the replace() call.

You can use finish() method or you can use:

android:noHistory="true"

And then there is no need to call finish() anymore.

<activity android:name=".ClassName" android:noHistory="true" ... />

You can use the combinat package with R 2.13:

install.packages("combinat")
require(combinat)
permn(3)
combn(3, 2)

If you want to know the number of combination/permutations, then check the size of the result, e.g.:

length(permn(3))
dim(combn(3,2))[2]

I had the same problem with AngularJS and Node.js + Express 4 + Router

Router expects the data from post's request in body. This body was always empty if i followed the example from Angular Docs

Notation 1

$http.post('/someUrl', {msg:'hello word!'})

But if i used it in the data

Notation 2

$http({
       withCredentials: false,
       method: 'post',
       url: yourUrl,
       headers: {'Content-Type': 'application/x-www-form-urlencoded'},
       data: postData
 });

Edit 1:

Otherwise node.js router will expect the data in req.body if used notation 1:

req.body.msg

Which also sends the information as JSON payload. This is better in some cases where you have arrays in your json and x-www-form-urlencoded will give some problems.

it worked. Hope it helps.

If you'd like to check if the argument exists, you can check if the # of arguments is greater than or equal to your target argument number.

The following script demonstrates how this works

test.sh

#!/usr/bin/env bash

if [ $# -ge 3 ]
then
  echo script has at least 3 arguments
fi

produces the following output

$ ./test.sh
~
$ ./test.sh 1
~
$ ./test.sh 1 2
~
$ ./test.sh 1 2 3
script has at least 3 arguments
$ ./test.sh 1 2 3 4
script has at least 3 arguments

What is a when you call Ancestors('A',a)? If a['A'] is None, or if a['A'][0] is None, you'd receive that exception.

I think there is not similar function like data.shape in Spark. But I will use len(data.columns) rather than len(data.dtypes)

I think the confusion over here roots from the english. I mean __repr__(); short for 'representation' of the value I'm guessing, like @S.Lott said

"What is the difference between "an actual expression, that can ... recreate the object" and "a rehasing of the actual expression which was used [to create the object]"? Both are an expression that creates the object. There's no practical distinction between these. A repr call could produce either a new expression or the original expression. In many cases, they're the same."

But in some cases they might be different. E.g; coordinate points, you might want c.coordinate to return: 3,5 but c.__repr__ to return Coordinate(3, 5). Hope that makes more sense...

I very often use classes, rather than functions, for my decorators. I was having some trouble with this because an object won't have all the same attributes that are expected of a function. For example, an object won't have the attribute __name__. I had a specific issue with this that was pretty hard to trace where Django was reporting the error "object has no attribute '__name__'". Unfortunately, for class-style decorators, I don't believe that @wrap will do the job. I have instead created a base decorator class like so:

class DecBase(object):
    func = None

    def __init__(self, func):
        self.__func = func

    def __getattribute__(self, name):
        if name == "func":
            return super(DecBase, self).__getattribute__(name)

        return self.func.__getattribute__(name)

    def __setattr__(self, name, value):
        if name == "func":
            return super(DecBase, self).__setattr__(name, value)

        return self.func.__setattr__(name, value)

This class proxies all the attribute calls over to the function that is being decorated. So, you can now create a simple decorator that checks that 2 arguments are specified like so:

class process_login(DecBase):
    def __call__(self, *args):
        if len(args) != 2:
            raise Exception("You can only specify two arguments")

        return self.func(*args)

Simple example with good coding practices and covering all cases :

 private static void fetchIndexSafely(String url) throws FileAlreadyExistsException {
        File f = new File(Constants.RFC_INDEX_LOCAL_NAME);
        if (f.exists()) {
            throw new FileAlreadyExistsException(f.getAbsolutePath());
        } else {
            try {
                URL u = new URL(url);
                FileUtils.copyURLToFile(u, f);
            } catch (MalformedURLException ex) {
                Logger.getLogger(RfcFetcher.class.getName()).log(Level.SEVERE, null, ex);
            } catch (IOException ex) {
                Logger.getLogger(RfcFetcher.class.getName()).log(Level.SEVERE, null, ex);
            }
        }
    }

You could get first rows of Spark DataFrame with head and then create Pandas DataFrame:

l = [('Alice', 1),('Jim',2),('Sandra',3)]
df = sqlContext.createDataFrame(l, ['name', 'age'])

df_pandas = pd.DataFrame(df.head(3), columns=df.columns)

In [4]: df_pandas
Out[4]: 
     name  age
0   Alice    1
1     Jim    2
2  Sandra    3

With support for C++11 initializer lists it is very easy:

#include <iostream>
#include <vector>
#include <string>
using namespace std;

using Strings = vector<string>;

void foo( Strings const& strings )
{
    for( string const& s : strings ) { cout << s << endl; }
}

auto main() -> int
{
    foo( Strings{ "hi", "there" } ); 
}

Lacking that (e.g. for Visual C++ 10.0) you can do things like this:

#include <iostream>
#include <vector>
#include <string>
using namespace std;

typedef vector<string> Strings;

void foo( Strings const& strings )
{
    for( auto it = begin( strings );  it != end( strings );  ++it )
    {
        cout << *it << endl;
    }
}

template< class Elem >
vector<Elem>& r( vector<Elem>&& o ) { return o; }

template< class Elem, class Arg >
vector<Elem>& operator<<( vector<Elem>& v, Arg const& a )
{
    v.push_back( a );
    return v;
}

int main()
{
    foo( r( Strings() ) << "hi" << "there" ); 
}

You can do this using sed: sed '/help/ d' < inputFile > outputFile

PHP escapes forward slashes by default which is probably why this appears so commonly. I'm not sure why, but possibly because embedding the string "</script>" inside a <script> tag is considered unsafe.

This functionality can be disabled by passing in the JSON_UNESCAPED_SLASHES flag but most developers will not use this since the original result is already valid JSON.

Another solution:

if (view == null) {
    view = inflater.inflate(R.layout.nearbyplaces, container, false);
}

That's it, if not null you don't need to reinitialize it removing from parent is unnecessary step.

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP version specific installation (if PHP 7.4 installed)

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring

You may need other PHP extensions for your composer packages. Find from links below.

If you restructured your date format into YYYY/MM/DD then you can use this simple string ordering to achieve the formating you need.

Alternatively, using the SUBSTR(store_name,start,length) command you should be able to restructure the sorting term into the above format

perhaps using the following

SELECT     *
FROM         vw_view
ORDER BY SUBSTR(EventDate,6,4) + SUBSTR(EventDate, 0, 5) DESC

1. for error: unescaped apostrophe in string

what I found is that AAPT2 tool points to wrong row in xml, sometimes. So you should correct whole strings.xml file

In Android Studio, in problem file use :

Edit->find->replace

Then write in first field \' (or \&,>,\<,\")
in second put '(or &,>,<,")
then replace each if needed.(or "reptlace all" in case with ')
Then in first field again put '(or &,>,<,")
and in second write \'
then replace each if needed.(or "replace all" in case with ')

2. for other problematic symbols
I use to comment each next half part +rebuild until i won't find the wrong sign.

E.g. an escaped word "\update" unexpectedly drops such error :)

Explode string by one or more spaces or tabs in php example as follow: 

   <?php 
       $str = "test1 test2   test3        test4"; 
       $result = preg_split('/[\s]+/', $str);
       var_dump($result);  
    ?>

   /** To seperate by spaces alone: **/
    <?php
      $string = "p q r s t";   
      $res = preg_split('/ +/', $string);
      var_dump($res);
    ?>

The issue was in my code.

In large code base, issue was not clear.

A simplified code is below:

Bad:

 collection.insertMany(
    [[],
    function (err, result) {
    });

Good:

collection.insertMany(
    [],
    function (err, result) {
    });

That is, the first one has [[], instead of normal array []

TS error was not clear enough, and it showed error in the last line with });

Hope this helps.

Update 2018-10-16

Reportedly, as of VS 2013, this warning can be disabled. See the comment by @Mark Ransom.

Original Answer

You can't disable that specific warning.

According to Geoff Chappell the 4099 warning is treated as though it's too important to ignore, even by using in conjunction with /wx (which would treat warnings as errors and ignore the specified warning in other situations)

Here is the relevant text from the link:

Not Quite Unignorable Warnings

For some warning numbers, specification in a /ignore option is accepted but not necessarily acted upon. Should the warning occur while the /wx option is not active, then the warning message is still displayed, but if the /wx option is active, then the warning is ignored. It is as if the warning is thought important enough to override an attempt at ignoring it, but not if the user has put too high a price on unignored warnings.

The following warning numbers are affected:

4200, 4203, 4204, 4205, 4206, 4207, 4208, 4209, 4219, 4231 and 4237

Math.floor(n)

where n is a double. This'll actually return a double, it seems, so make sure that you typecast it after.

There are a few problems here.

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

2: you need a place to render the error.

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

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

Another simple way would be using a root explorer app on your phone.

Then go to /data/data/package name/shared preferences folder/name of your preferences.xml, you can use ES File explorer, and go to the root of your device, not sd card.

You can run maven in offline mode mvn -o install. Of course any artifacts not available in your local repository will fail. Maven is not predicated on distributed repositories, but they certainly make things more seamless. Its for this reason that many shops use internal mirrors that are incrementally synced with the central repos.

In addition, the mvn dependency:go-offline can be used to ensure you have all of your dependencies installed locally before you begin to work offline.

I wanted a random integer converted into a six-digit hex string with a # at the beginning. To get this I used

"#%6x" % random.randint(0xFFFFFF)

You can use the command wget to download from command line. Specifically, you could use

wget http://download.oracle.com/otn-pub/java/jdk/7u10-b18/jdk-7u10-linux-x64.tar.gz

However because Oracle requires you to accept a license agreement this may not work (and I am currently unable to test it).

In order to answer your question, we need two elements:

1. Understanding of the characteristics of different architecture styles/patterns.
2. Understanding of the characteristics of different programming paradigms.

A list of software architecture styles/pattern is shown on the software architecture article on Wikipeida. And you can research on them easily on the web.

In short and general, Procedural is good for a model that follows a procedure, OOP is good for design, and Functional is good for high level programming.

I think you should try reading the history on each paradigm and see why people create it and you can understand them easily.

After understanding them both, you can link the items of architecture styles/patterns to programming paradigms.

This works fine

<?php
      $con=mysqli_connect("localhost","my_user","my_password","my_db");
      $con->query("SET GLOBAL time_zone = 'Asia/Calcutta'");
      $con->query("SET time_zone = '+05:30'");
      $con->query("SET @@session.time_zone = '+05:30'");
?>

Use zip(*list):

>>> l = [(1,2), (3,4), (8,9)]
>>> list(zip(*l))
[(1, 3, 8), (2, 4, 9)]

The zip() function pairs up the elements from all inputs, starting with the first values, then the second, etc. By using *l you apply all tuples in l as separate arguments to the zip() function, so zip() pairs up 1 with 3 with 8 first, then 2 with 4 and 9. Those happen to correspond nicely with the columns, or the transposition of l.

zip() produces tuples; if you must have mutable list objects, just map() the tuples to lists or use a list comprehension to produce a list of lists:

map(list, zip(*l))          # keep it a generator
[list(t) for t in zip(*l)]  # consume the zip generator into a list of lists

Either use a User Defined Table

Or you can use CSV by defining your own CSV function as per This Post.

I'd probably recommend the second method, as your stored proc is already written in the correct format and you'll find it handy later on if you need to do this down the road.

Cheers!

You can only select a value with the following two ways:

// First way to get a value
value = $("#txt_name").val(); 

// Second way to get a value
value = $("#txt_name").attr('value');

If you want to use straight JavaScript to get the value, here is how:

document.getElementById('txt_name').value 

You are correct that your cTag class must implement IComparable<T> interface. Then you can just call Sort() on your list.

To implement IComparable<T> interface, you must implement CompareTo(T other) method. The easiest way to do this is to call CompareTo method of the field you want to compare, which in your case is date.

public class cTag:IComparable<cTag> {
    public int id { get; set; }
    public int regnumber { get; set; }
    public string date { get; set; }
    public int CompareTo(cTag other) {
        return date.CompareTo(other.date);
    }
}

However, this wouldn't sort well, because this would use classic sorting on strings (since you declared date as string). So I think the best think to do would be to redefine the class and to declare date not as string, but as DateTime. The code would stay almost the same:

public class cTag:IComparable<cTag> {
    public int id { get; set; }
    public int regnumber { get; set; }
    public DateTime date { get; set; }
    public int CompareTo(cTag other) {
        return date.CompareTo(other.date);
    }
}

Only thing you'd have to do when creating the instance of the class to convert your string containing the date into DateTime type, but it can be done easily e.g. by DateTime.Parse(String) method.

reserve when you do not want the objects to be initialized when reserved. also, you may prefer to logically differentiate and track its count versus its use count when you resize. so there is a behavioral difference in the interface - the vector will represent the same number of elements when reserved, and will be 100 elements larger when resized in your scenario.

Is there any better choice in this kind of scenario?

it depends entirely on your aims when fighting the default behavior. some people will favor customized allocators -- but we really need a better idea of what it is you are attempting to solve in your program to advise you well.

fwiw, many vector implementations will simply double the allocated element count when they must grow - are you trying to minimize peak allocation sizes or are you trying to reserve enough space for some lock free program or something else?

Assuming you really mean easiest and are not necessarily looking for a way to do this programmatically, you can do this:

1. Add, if not already there, a row of "column Musicians" to the spreadsheet. That is, if you have data in columns such as:

   Rory Gallagher      Guitar
   Gerry McAvoy        Bass
   Rod de'Ath          Drums
   Lou Martin          Keyboards
   Donkey Kong Sioux   Self-Appointed Semi-official Stomper
   

   Note: you might want to add "Musician" and "Instrument" in row 0 (you might have to insert a row there)

2. Save the file as a CSV file.

3. Copy the contents of the CSV file to the clipboard

4. Go to http://www.convertcsv.com/csv-to-json.htm

5. Verify that the "First row is column names" checkbox is checked

6. Paste the CSV data into the content area

7. Mash the "Convert CSV to JSON" button

   With the data shown above, you will now have:

   [
     {
       "MUSICIAN":"Rory Gallagher",
       "INSTRUMENT":"Guitar"
     },
     {
       "MUSICIAN":"Gerry McAvoy",
       "INSTRUMENT":"Bass"
     },
     {
       "MUSICIAN":"Rod D'Ath",
       "INSTRUMENT":"Drums"
     },
     {
       "MUSICIAN":"Lou Martin",
       "INSTRUMENT":"Keyboards"
     }
     {
       "MUSICIAN":"Donkey Kong Sioux",
       "INSTRUMENT":"Self-Appointed Semi-Official Stomper"
     }
   ]
   

   With this simple/minimalistic data, it's probably not required, but with large sets of data, it can save you time and headache in the proverbial long run by checking this data for aberrations and abnormalcy.

8. Go here: http://jsonlint.com/

9. Paste the JSON into the content area

10. Pres the "Validate" button.

If the JSON is good, you will see a "Valid JSON" remark in the Results section below; if not, it will tell you where the problem[s] lie so that you can fix it/them.

I'll try to make the shortest definition I can manage using OOP terms:

A generic class CMonadic<T> is a monad if it defines at least the following methods:

class CMonadic<T> { 
    static CMonadic<T> create(T t);  // a.k.a., "return" in Haskell
    public CMonadic<U> flatMap<U>(Func<T, CMonadic<U>> f); // a.k.a. "bind" in Haskell
}

and if the following laws apply for all types T and their possible values t

left identity:

CMonadic<T>.create(t).flatMap(f) == f(t)

right identity

instance.flatMap(CMonadic<T>.create) == instance

associativity:

instance.flatMap(f).flatMap(g) == instance.flatMap(t => f(t).flatMap(g))

Examples:

A List monad may have:

List<int>.create(1) --> [1]

And flatMap on the list [1,2,3] could work like so:

intList.flatMap(x => List<int>.makeFromTwoItems(x, x*10)) --> [1,10,2,20,3,30]

Iterables and Observables can also be made monadic, as well as Promises and Tasks.

Commentary:

Monads are not that complicated. The flatMap function is a lot like the more commonly encountered map. It receives a function argument (also known as delegate), which it may call (immediately or later, zero or more times) with a value coming from the generic class. It expects that passed function to also wrap its return value in the same kind of generic class. To help with that, it provides create, a constructor that can create an instance of that generic class from a value. The return result of flatMap is also a generic class of the same type, often packing the same values that were contained in the return results of one or more applications of flatMap to the previously contained values. This allows you to chain flatMap as much as you want:

intList.flatMap(x => List<int>.makeFromTwo(x, x*10))
       .flatMap(x => x % 3 == 0 
                   ? List<string>.create("x = " + x.toString()) 
                   : List<string>.empty())

It just so happens that this kind of generic class is useful as a base model for a huge number of things. This (together with the category theory jargonisms) is the reason why Monads seem so hard to understand or explain. They're a very abstract thing and only become obviously useful once they're specialized.

For example, you can model exceptions using monadic containers. Each container will either contain the result of the operation or the error that has occured. The next function (delegate) in the chain of flatMap callbacks will only be called if the previous one packed a value in the container. Otherwise if an error was packed, the error will continue to propagate through the chained containers until a container is found that has an error handler function attached via a method called .orElse() (such a method would be an allowed extension)

Notes: Functional languages allow you to write functions that can operate on any kind of a monadic generic class. For this to work, one would have to write a generic interface for monads. I don't know if its possible to write such an interface in C#, but as far as I know it isn't:

interface IMonad<T> { 
    static IMonad<T> create(T t); // not allowed
    public IMonad<U> flatMap<U>(Func<T, IMonad<U>> f); // not specific enough,
    // because the function must return the same kind of monad, not just any monad
}

<style>
#aspectRatio
{
  position:fixed;
  left:0px;
  top:0px;
  width:60vw;
  height:40vw;
  border:1px solid;
  font-size:10vw;
}
</style>
<body>
<div id="aspectRatio">Aspect Ratio?</div>
</body>

The key thing to note here is vw = viewport width, and vh = viewport height

Doing borders on tables with css is a bit more complicated (but not as much, see this jsfiddle as example):

table {_x000D_
  border-collapse: collapse;_x000D_
  border: 1px solid black;_x000D_
}_x000D_
_x000D_
table td {_x000D_
  border: 1px solid black;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <td>test</td>_x000D_
    <td>test</td>_x000D_
  </tr>_x000D_
</table>

You probably haven't added a reference to Microsoft XML (any version) for Dim objHTTP As New MSXML2.XMLHTTP in the VBA window's Tools/References... dialog.

Also, it's a good idea to avoid using late binding (CreateObject...); better to use early binding (Dim objHTTP As New MSXML2.XMLHTTP), as early binding allows you to use Intellisense to list the members and do all sorts of design-time validation.

escape() and unescape() are intended to encode / decode strings for URLs, not HTML.

Actually, I use the following snippet to do the trick that doesn't require any framework:

var escapedHtml = html.replace(/&/g, '&')
                      .replace(/>/g, '>')
                      .replace(/</g, '&lt;')
                      .replace(/"/g, '&quot;')

Maybe you cannot use manifest class from generated code in your project. So, you can use manifest class from android sdk "android.Manifest.permission.WRITE_EXTERNAL_STORAGE". But in Marsmallow version have 2 permission must grant are WRITE and READ EXTERNAL STORAGE in storage category. See my program, my program will request permission until user choose yes and do something after permissions is granted.

            if (Build.VERSION.SDK_INT >= 23) {
                if (ContextCompat.checkSelfPermission(LoginActivity.this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
                        != PackageManager.PERMISSION_GRANTED || ContextCompat.checkSelfPermission(LoginActivity.this, android.Manifest.permission.READ_EXTERNAL_STORAGE)
                        != PackageManager.PERMISSION_GRANTED) {
                    ActivityCompat.requestPermissions(LoginActivity.this,
                            new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE, android.Manifest.permission.READ_EXTERNAL_STORAGE},
                            1);
                } else {
                    //do something
                }
            } else {
                    //do something
            }

Try Below Simple Ruby Magics :)

(1..x).each { |n| puts n }
x.times { |n| puts n }
1.upto(x) { |n| print n }

That is the version number of the Ionic CLI, which is different from the version number of Ionic's library. Here are a couple easy ways to check the version.

In the browser console, you can run ionic.version and it will print to the console what version it is.

You can also look at the bower.json file in your app, and it will show the version number like you see here. https://github.com/ionic-in-action/chapter5/blob/master/bower.json#L5

For shared libraries libNAME.so the -D switch was necessary to see symbols in my Linux

nm -D libNAME.so

and for static library as reported by others

nm -g libNAME.a

I am using mysql 8.0.12 and updating the mysql connector to mysql-connector-java-8.0.12 resolved the issue for me.

Hope it helps somebody.

Since Jackson is being used, you have to configure that as a Jackson property. In the case of Spring Boot REST services, you have to configure it in application.properties or application.yml:

spring.jackson.default-property-inclusion = NON_NULL

Check out the MSDN page for SortedList:

From Remarks section:

The SortedList<(Of <(TKey, TValue>)>) generic class is a binary search tree with O(log n) retrieval, where n is the number of elements in the dictionary. In this, it is similar to the SortedDictionary<(Of <(TKey, TValue>)>) generic class. The two classes have similar object models, and both have O(log n) retrieval. Where the two classes differ is in memory use and speed of insertion and removal:

• SortedList<(Of <(TKey, TValue>)>) uses less memory than SortedDictionary<(Of <(TKey, TValue>)>).

• SortedDictionary<(Of <(TKey, TValue>)>) has faster insertion and removal operations for unsorted data, O(log n) as opposed to O(n) for SortedList<(Of <(TKey, TValue>)>).

• If the list is populated all at once from sorted data, SortedList<(Of <(TKey, TValue>)>) is faster than SortedDictionary<(Of <(TKey, TValue>)>).

If U want to delete more than one characters, say comma and dots you can write

<script type="text/javascript">
  var mystring = "It,is,a,test.string,of.mine" 
  mystring = mystring.replace(/[,.]/g , ''); 
  alert( mystring);
</script>

You could also use Hex Color Code,

Name    Hex Color Code  RGB Color Code
Red     #FF0000         rgb(255, 0, 0)
Maroon  #800000         rgb(128, 0, 0)
Yellow  #FFFF00         rgb(255, 255, 0)
Olive   #808000         rgb(128, 128, 0)

For example

import matplotlib.pyplot as plt
import random

number_of_colors = 8

color = ["#"+''.join([random.choice('0123456789ABCDEF') for j in range(6)])
             for i in range(number_of_colors)]
print(color)

['#C7980A', '#F4651F', '#82D8A7', '#CC3A05', '#575E76', '#156943', '#0BD055', '#ACD338']

Lets try plotting them in a scatter plot

for i in range(number_of_colors):
    plt.scatter(random.randint(0, 10), random.randint(0,10), c=color[i], s=200)

plt.show()

I recommend using a cache-buster in the wsdl url.

In our apps we use a SVN Revision id in the wsdl url so the client immediately knows of changing structures. This works on our app because, everytime we change the server-side, we also need to adjust the client accordingly.

$client = new SoapClient('http://somewhere.com/?wsdl&rev=$Revision$');

This requires svn to be configured properly. Not on all repositories this is enabled by default.

In case you are not responsible for both components (server,client) or you don't use SVN you may find another indicator which can be utilised as a cache-buster in your wsdl url.

Here is one way that I hope is easy to understand:

http://jsfiddle.net/tft4t/

$(document).ready(function() {
 $("#chkdwn2").click(function() {
   if ($(this).is(":checked")) {
      $("#dropdown").prop("disabled", true);
   } else {
      $("#dropdown").prop("disabled", false);  
   }
 });
});

With sprintf.js in place - one can make a nifty little format-thingy

String.prototype.format = function(){
    var _args = arguments 
    Array.prototype.unshift.apply(_args,[this])
    return sprintf.apply(undefined,_args)
}   
// this gives you:
"{%1$s}{%2$s}".format("1", "0")
// {1}{0}

By entering $PATH on its own at the command prompt, you're trying to run it. This isn't like Windows where you can get your path output by simply typing path.

If you want to see what the path is, simply echo it:

echo $PATH

Is something along these lines what you are looking for?

x1 = function(x){
  mu = mean(x)
  l1 = list(s1=table(x),std=sd(x))
  return(list(l1,mu))
}

library(Ecdat)
data(Fair)
x1(Fair$age)

I had this problem too but managed to solve it, the error is that ur computer has saved a git username and password so if you shift to another account the error 403 will appear. Below is the solution For Windows you can find the keys here:

control panel > user accounts > credential manager > Windows credentials > Generic credentials

Next remove the Github keys.

Since Java 10 it is possible to use

Map.copyOf

for creating a shallow copy, which is also immutable. (Here is its Javadoc). For a deep copy, as mentioned in this answer you, need some kind of value mapper to make a safe copy of values. You don't need to copy keys though, since they must be immutable.

I had the same issue and I have tried many answers but nothing worked.

I tried the following and it worked successfully :

<input type=text  data-date-format='yy-mm-dd'  > 

This is now part of the language. See TypeScriptLang.org > Basic Types > enum for the documentation on this. An excerpt from the documentation on how to use these enums:

enum Color {Red, Green, Blue};
var c: Color = Color.Green;

Or with manual backing numbers:

enum Color {Red = 1, Green = 2, Blue = 4};
var c: Color = Color.Green;

You can also go back to the enum name by using for example Color[2].

Here's an example of how this all goes together:

module myModule {
    export enum Color {Red, Green, Blue};

    export class MyClass {
        myColor: Color;

        constructor() {
            console.log(this.myColor);
            this.myColor = Color.Blue;
            console.log(this.myColor);
            console.log(Color[this.myColor]);
        }
    }
}

var foo = new myModule.MyClass();

This will log:

undefined  
2  
Blue

Because, at the time of writing this, the Typescript Playground will generate this code:

var myModule;
(function (myModule) {
    (function (Color) {
        Color[Color["Red"] = 0] = "Red";
        Color[Color["Green"] = 1] = "Green";
        Color[Color["Blue"] = 2] = "Blue";
    })(myModule.Color || (myModule.Color = {}));
    var Color = myModule.Color;
    ;
    var MyClass = (function () {
        function MyClass() {
            console.log(this.myColor);
            this.myColor = Color.Blue;
            console.log(this.myColor);
            console.log(Color[this.myColor]);
        }
        return MyClass;
    })();
    myModule.MyClass = MyClass;
})(myModule || (myModule = {}));
var foo = new myModule.MyClass();

Well I was able to install it by :

sudo apt-get install php-curl

on my system. This will install a dependency package, which depends on the default php version.

After that restart apache

sudo service apache2 restart

In the aspx page load event, add an onkeypress to the box.

this.TextBox1.Attributes.Add(
    "onkeypress", "button_click(this,'" + this.Button1.ClientID + "')");

Then add this javascript to evaluate the key press, and if it is "enter," click the right button.

<script>
    function button_click(objTextBox,objBtnID)
    {
        if(window.event.keyCode==13)
        {
            document.getElementById(objBtnID).focus();
            document.getElementById(objBtnID).click();
        }
    }
</script>

Use iloc to access by position (rather than label):

In [11]: df = pd.DataFrame([[1, 2], [3, 4]], ['a', 'b'], ['A', 'B'])

In [12]: df
Out[12]: 
   A  B
a  1  2
b  3  4

In [13]: df.iloc[0]  # first row in a DataFrame
Out[13]: 
A    1
B    2
Name: a, dtype: int64

In [14]: df['A'].iloc[0]  # first item in a Series (Column)
Out[14]: 1

Create a C# class that maps to your Json and use Newsoft JsonConvert to Deserialise it.

For example:

public Class MyResponse
{
    public Meta Meta { get; set; }
    public Response Response { get; set; }
}

You can very easily create an EXE (for Windows) without using any cryptic build commands. You can do it right in Visual Studio.

1. Right click the Console App Project and select Publish.
2. A new page will open up (screen shot below)
3. Hit Configure...
4. Then change Deployment Mode to Self-contained or Framework dependent. .NET Core 3.0 introduces a Single file deployment which is a single executable.
5. Use "framework dependent" if you know the target machine has a .NET Core runtime as it will produce fewer files to install.
6. If you now view the bin folder in explorer, you will find the .exe file.
7. You will have to deploy the exe along with any supporting config and dll files.

    An example of reading a file:
Dim sFileText as String
Dim iFileNo as Integer
iFileNo = FreeFile
'open the file for reading
Open "C:\Test.txt" For Input As #iFileNo
'change this filename to an existing file! (or run the example below first)

'read the file until we reach the end
Do While Not EOF(iFileNo)
Input #iFileNo, sFileText
'show the text (you will probably want to replace this line as appropriate to your program!)
MsgBox sFileText
Loop

'close the file (if you dont do this, you wont be able to open it again!)
Close #iFileNo
(note: an alternative to Input # is Line Input # , which reads whole lines).


An example of writing a file:
Dim sFileText as String
Dim iFileNo as Integer
iFileNo = FreeFile
'open the file for writing
Open "C:\Test.txt" For Output As #iFileNo
'please note, if this file already exists it will be overwritten!

'write some example text to the file
Print #iFileNo, "first line of text"
Print #iFileNo, " second line of text"
Print #iFileNo, "" 'blank line
Print #iFileNo, "some more text!"

'close the file (if you dont do this, you wont be able to open it again!)
Close #iFileNo

Short answer: While it's technically possible to send 100k e-mails each week yourself, the simplest, easiest and cheapest solution is to outsource this to one of the companies that specialize in it (I did say "cheapest": there's no limit to the amount of development time (and therefore money) that you can sink into this when trying to DIY).

Long answer: If you decide that you absolutely want to do this yourself, prepare for a world of hurt (after all, this is e-mail/e-fail we're talking about). You'll need:

• e-mail content that is not spam (otherwise you'll run into additional major roadblocks on every step, even legal repercussions)
• in addition, your content should be easy to distinguish from spam - that may be a bit hard to do in some cases (I heard that a certain pharmaceutical company had to all but abandon e-mail, as their brand names are quite common in spams)
• a configurable SMTP server of your own, one which won't buckle when you dump 100k e-mails onto it (your ISP's upstream server won't be sufficient here and you'll make the ISP violently unhappy; we used two dedicated boxes)
• some mail wrapper (e.g. PhpMailer if PHP's your poison of choice; using PHP's mail() is horrible enough by itself)
• your own sender function to run in a loop, create the mails and pass them to the wrapper (note that you may run into PHP's memory limits if your app has a memory leak; you may need to recycle the sending process periodically, or even better, decouple the "creating e-mails" and "sending e-mails" altogether)

Surprisingly, that was the easy part. The hard part is actually sending it:

• some servers will ban you when you send too many mails close together, so you need to shuffle and watch your queue (e.g. send one mail to [email protected], then three to other domains, only then another to [email protected])
• you need to have correct PTR, SPF, DKIM records
• handling remote server timeouts, misconfigured DNS records and other network pleasantries
• handling invalid e-mails (and no, regex is the wrong tool for that)
• handling unsubscriptions (many legitimate newsletters have been reclassified as spam due to many frustrated users who couldn't unsubscribe in one step and instead chose to "mark as spam" - the spam filters do learn, esp. with large e-mail providers)
• handling bounces and rejects ("no such mailbox [email protected]","mailbox [email protected] full")
• handling blacklisting and removal from blacklists (Sure, you're not sending spam. Some recipients won't be so sure - with such large list, it will happen sometimes, no matter what precautions you take. Some people (e.g. your not-so-scrupulous competitors) might even go as far to falsely report your mailings as spam - it does happen. On average, it takes weeks to get yourself removed from a blacklist.)

And to top it off, you'll have to manage the legal part of it (various federal, state, and local laws; and even different tangles of laws once you send outside the U.S. (note: you have no way of finding if [email protected] lives in Southwest Elbonia, the country with world's most draconian antispam laws)).

I'm pretty sure I missed a few heads of this hydra - are you still sure you want to do this yourself? If so, there'll be another wave, this time merely the annoying problems inherent in sending an e-mail. (You see, SMTP is a store-and-forward protocol, which means that your e-mail will be shuffled across many SMTP servers around the Internet, in the hope that the next one is a bit closer to the final recipient. Basically, the e-mail is sent to an SMTP server, which puts it into its forward queue; when time comes, it will forward it further to a different SMTP server, until it reaches the SMTP server for the given domain. This forward could happen immediately, or in a few minutes, or hours, or days, or never.) Thus, you'll see the following issues - most of which could happen en route as well as at the destination:

• the remote SMTP servers don't want to talk to your SMTP server
• your mails are getting marked as spam (<blink> is not your friend here, nor is <font color=...>)
• your mails are delivered days, even weeks late (contrary to popular opinion, SMTP is designed to make a best effort to deliver the message sometime in the future - not to deliver it now)
• your mails are not delivered at all (already sent from e-mail server on hop #4, not sent yet from server on hop #5, the server that currently holds the message crashes, data is lost)
• your mails are mangled by some braindead server en route (this one is somewhat solvable with base64 encoding, but then the size goes up and the e-mail looks more suspicious)
• your mails are delivered and the recipients seem not to want them ("I'm sure I didn't sign up for this, I remember exactly what I did a year ago" (of course you do, sir))
• users with various versions of Microsoft Outlook and its special handling of Internet mail
• wizard's apprentice mode (a self-reinforcing positive feedback loop - in other words, automated e-mails as replies to automated e-mails as replies to...; you really don't want to be the one to set this off, as you'd anger half the internet at yourself)

and it'll be your job to troubleshoot and solve this (hint: you can't, mostly). The people who run a legit mass-mailing businesses know that in the end you can't solve it, and that they can't solve it either - and they have the reasons well researched, documented and outlined (maybe even as a Powerpoint presentation - complete with sounds and cool transitions - that your bosses can understand), as they've had to explain this a million times before. Plus, for the problems that are actually solvable, they know very well how to solve them.

If, after all this, you are not discouraged and still want to do this, go right ahead: it's even possible that you'll find a better way to do this. Just know that the road ahead won't be easy - sending e-mail is trivial, getting it delivered is hard.

Try this:

$('#id').change();

Works for me.

On one line together with setting the value: $('#id').val(16).change();

layout_margin is a constraint that a view child tell to its parent. However it is the parent's role to choose whether to allow margin or not. Basically by setting android:layout_margin="10dp", the child is pleading the parent view group to allocate space that is 10dp bigger than its actual size. (padding="10dp", on the other hand, means the child view will make its own content 10dp smaller.)

Consequently, not all ViewGroups respect margin. The most notorious example would be listview, where the margins of items are ignored. Before you call setMargin() to a LayoutParam, you should always make sure that the current view is living in a ViewGroup that supports margin (e.g. LinearLayouot or RelativeLayout), and cast the result of getLayoutParams() to the specific LayoutParams you want. (ViewGroup.LayoutParams does not even have setMargins() method!)

The function below should do the trick. However make sure you substitute RelativeLayout to the type of the parent view.

private void setMargin(int marginInPx) {
    RelativeLayout.LayoutParams lp = (RelativeLayout.LayoutParams) getLayoutParams();
    lp.setMargins(marginInPx,marginInPx, marginInPx, marginInPx);
    setLayoutParams(lp);
}

import sys
sys.exit()

In Windows 7 it is at the path

C:\Users\[username]\.android

• goto this path and remove debug.keystore
• clean and build your project.

The simplest thing you can do is cherry picking a range. It does the same as the rebase --onto but is easier for the eyes :)

git cherry-pick quickfix1..quickfix2

This should work for Firefox by using AutoAuth plugin:

FirefoxProfile firefoxProfile = new ProfilesIni().getProfile("default");
File ffPluginAutoAuth = new File("D:\\autoauth-2.1-fx+fn.xpi");
firefoxProfile.addExtension(ffPluginAutoAuth);
driver = new FirefoxDriver(firefoxProfile);

Exact transfer to Angular2+ is as below:

<button (click)="myFunc()"></button>

also in your component file:

import { Component, OnInit } from "@angular/core";

@Component({
  templateUrl:"button.html" //this is the component which has the above button html
})

export class App implements OnInit{
  constructor(){}

  ngOnInit(){

  }

  myFunc(){
    console.log("function called");
  }
}

I agree with BMSAndroidDroid and Flo-Scheild-Bobby. I was doing a tutorial called DailyQuote and had used the Cordova library. I then changed my OS from Windows to Ubuntu and tried to import projects into Eclipse, (I'm using Eclipse Juno 64-bit, on Ubuntu 12.04 64-bit, Oracle JDK 7. I also installed the Ubuntu 32-bit libs- so no issues with 64 and 32bit), and got the same issue.

As suggested by Flo-Scheild-Bobby, open configure build path and add the jar(s) again that you added before. Then remove the old jar link(s) and thats it.

fastest way is by signing with the debug keystore:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ~/.android/debug.keystore app.apk androiddebugkey -storepass android

or on Windows:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore %USERPROFILE%/.android/debug.keystore test.apk androiddebugkey -storepass android

In Bootstrap 3 I've added a table-no-border class

.table-no-border>thead>tr>th, 
.table-no-border>tbody>tr>th, 
.table-no-border>tfoot>tr>th, 
.table-no-border>thead>tr>td, 
.table-no-border>tbody>tr>td, 
.table-no-border>tfoot>tr>td {
  border-top: none; 
}

Integer.toString(1100) gives you the integer as a string. Integer.toString(1100).getBytes() to get an array of bytes of the individual digits.

Edit:

You can convert the character digits into numeric digits, thus:

  String string = Integer.toString(1234);
  int[] digits = new int[string.length()];

  for(int i = 0; i<string.length(); ++i){
    digits[i] = Integer.parseInt(string.substring(i, i+1));
  }
  System.out.println("digits:" + Arrays.toString(digits));

As others have said you can't do what you are asking. If you describe the problem you are trying to solve maybe someone can help?

E.g.

• are you trying to uniquely identify your users?
• Could you use a cookie, or the session ID perhaps instead of the IP address?

Edit The address you see on the server shouldn't be the ISP's address, as you say that would be a huge range. The address for a home user on broadband will be the address at their router, so every device inside the house will appear on the outside to be the same, but the router uses NAT to ensure that traffic is routed to each device correctly. For users accessing from an office environment the address may well be the same for all users. Sites that use IP address for ID run the risk of getting it very wrong - the examples you give are good ones and they often fail. For example my office is in the UK, the breakout point (where I "appear" to be on the internet) is in another country where our main IT facility is, so from my office my IP address appears to be not in the UK. For this reason I can't access UK only web content, such as the BBC iPlayer). At any given time there would be hundreds, or even thousands, of people at my company who appear to be accessing the web from the same IP address.

When you are writing server code you can never be sure what the IP address you see is referring to. Some users like it this way. Some people deliberately use a proxy or VPN to further confound you.

When you say your machine address is different to the IP address shown on StackOverflow, how are you finding out your machine address? If you are just looking locally using ipconfig or something like that I would expect it to be different for the reasons I outlined above. If you want to double check what the outside world thinks have a look at whatismyipaddress.com/.

This Wikipedia link on NAT will provide you some background on this.

I recommend looking at modern databases like NoSQL and also I agree with user1252434's post. For instance I am storing a few < 500kb PNGs as base64 on my Mongo db with binary set to true with no performance hit at all. Mongo can be used to store large files like 10MB videos and that can offer huge time saving advantages in metadata searches for those videos, see storing large objects and files in mongodb.

How about if you're copying each column in a sheet to different sheets? Example: row B of mysheet to row B of sheet1, row C of mysheet to row B of sheet 2...

Your question title mentions Blocking Queues. However, ConcurrentLinkedQueue is not a blocking queue.

The BlockingQueues are ArrayBlockingQueue, DelayQueue, LinkedBlockingDeque, LinkedBlockingQueue, PriorityBlockingQueue, and SynchronousQueue.

Some of these are clearly not fit for your purpose (DelayQueue, PriorityBlockingQueue, and SynchronousQueue). LinkedBlockingQueue and LinkedBlockingDeque are identical, except that the latter is a double-ended Queue (it implements the Deque interface).

Since ArrayBlockingQueue is only useful if you want to limit the number of elements, I'd stick to LinkedBlockingQueue.

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

As someone who doesn't know javascript, here's a PHP method that works for me and is easy to understand. My whole navbar is in a PHP function that is in a file of common components I include from my pages. So for example in my 'index.php' page I have... `

<?php
   $calling_file = basename(__FILE__);
   include 'my_common_includes.php';    // Going to use my navbar function "my_navbar"
   my_navbar($calling_file);    // Call the navbar function
 ?>

Then in the 'my_common_includes.php' I have...

<?php
   function my_navbar($calling_file)
   {
      // All your usual nabvbar code here up to the menu items
      if ($calling_file=="index.php")   {   echo '<li class="nav-item active">';    } else {    echo '<li class="nav-item">';   }
    echo '<a class="nav-link" href="index.php">Home</a>
</li>';
      if ($calling_file=="about.php")   {   echo '<li class="nav-item active">';    } else {    echo '<li class="nav-item">';   }
    echo '<a class="nav-link" href="about.php">About</a>
</li>';
      if ($calling_file=="galleries.php")   {   echo '<li class="nav-item active">';    } else {    echo '<li class="nav-item">';   }
    echo '<a class="nav-link" href="galleries.php">Galleries</a>
</li>';
       // etc for the rest of the menu items and closing out the navbar
     }
  ?>

\b matches at word boundaries (without actually matching any characters), so the following should do what you want:

\bstackoverflow\b

Give your body tag an overflow: scroll;

body {
    overflow: scroll;
}

or if you only want a vertical scrollbar use overflow-y

body {
    overflow-y: scroll;
}

I am trying to explain by putting problem statement and solution to it. I hope it will help

Problem Statement:

Find all the published products, whose name like ABC Product or PQR Product, and price should be less than 15/-

Solution:

Below are the conditions that need to be taken care of

1. Product price should be less than 15
2. Product name should be either ABC Product or PQR Product
3. Product should be in published state.

Below is the statement that applies above criterion to create query and fetch data.

$elements = $collection->find(
             Array(
                [price] => Array( [$lt] => 15 ),

In case you can't upgrade to Ruby on Rails 2.3.11 (and to expand on douglasr's answer), thread must be required at the top of boot.rb. For example:

require 'thread'

# Don't change this file!
# Configure your app in config/environment.rb and config/environments/*.rb
...

this is used to access the methods and fields of the current object. For this reason, it has no meaning in static methods, for example.

super allows access to non-private methods and fields in the super-class, and to access constructors from within the class' constructors only.

Without jQuery:

document.getElementById('file').onchange = function(){

  var file = this.files[0];

  var reader = new FileReader();
  reader.onload = function(progressEvent){
    // Entire file
    console.log(this.result);

    // By lines
    var lines = this.result.split('\n');
    for(var line = 0; line < lines.length; line++){
      console.log(lines[line]);
    }
  };
  reader.readAsText(file);
};

HTML:

<input type="file" name="file" id="file">

Remember to put your javascript code after the file field is rendered.

You can also look into using the Collection Object. This usually works better than an array for custom objects, since it dynamically sizes and has methods for:

• Add
• Count
• Remove
• Item(index)

Plus its normally easier to loop through a collection too since you can use the for...each structure very easily with a collection.

'size_t' and 'ptrdiff_t' are required to match your architecture (whatever it is). Therefore, I think rather than using 'int', you should be able to use 'size_t', which on a 64 bit system should be a 64 bit type.

This discussion unsigned int vs size_t goes into a bit more detail.

if (i % 2) {
return odd numbers
}

if (i % 2 - 1) {
return even numbers
}

Another method could be to split the string by ":" and then pop off the end. var newString = string.split(":").pop();

In answer to the first question. Straight from the Oracle documentation

A cursor is a pointer to a private SQL area that stores information about processing a specific SELECT or DML statement.

There are two primary contenders for python apps on Android

Chaquopy

https://chaquo.com/chaquopy/

This integrates with the Android build system, it provides a Python API for all android features. To quote the site "The complete Android API and user interface toolkit are directly at your disposal."

Beeware (Toga widget toolkit)

https://pybee.org/

This provides a multi target transpiler, supports many targets such as Android and iOS. It uses a generic widget toolkit (toga) that maps to the host interface calls.

Which One?

Both are active projects and their github accounts shows a fair amount of recent activity.

Beeware Toga like all widget libraries is good for getting the basics out to multiple platforms. If you have basic designs, and a desire to expand to other platforms this should work out well for you.

On the other hand, Chaquopy is a much more precise in its mapping of the python API to Android. It also allows you to mix in Java, useful if you want to use existing code from other resources. If you have strict design targets, and predominantly want to target Android this is a much better resource.

Here's a sample method that adds two extra columns programmatically to the grid view:

    private void AddColumnsProgrammatically()
    {
        // I created these columns at function scope but if you want to access 
        // easily from other parts of your class, just move them to class scope.
        // E.g. Declare them outside of the function...
        var col3 = new DataGridViewTextBoxColumn();
        var col4 = new DataGridViewCheckBoxColumn();

        col3.HeaderText = "Column3";
        col3.Name = "Column3";

        col4.HeaderText = "Column4";
        col4.Name = "Column4";

        dataGridView1.Columns.AddRange(new DataGridViewColumn[] {col3,col4});
    }

A great way to figure out how to do this kind of process is to create a form, add a grid view control and add some columns. (This process will actually work for ANY kind of form control. All instantiation and initialization happens in the Designer.) Then examine the form's Designer.cs file to see how the construction takes place. (Visual Studio does everything programmatically but hides it in the Form Designer.)

For this example I created two columns for the view named Column1 and Column2 and then searched Form1.Designer.cs for Column1 to see everywhere it was referenced. The following information is what I gleaned and, copied and modified to create two more columns dynamically:

// Note that this info scattered throughout the designer but can easily collected.

        System.Windows.Forms.DataGridViewTextBoxColumn Column1;
        System.Windows.Forms.DataGridViewCheckBoxColumn Column2;

        this.Column1 = new System.Windows.Forms.DataGridViewTextBoxColumn();
        this.Column2 = new System.Windows.Forms.DataGridViewCheckBoxColumn();

        this.dataGridView1.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {
        this.Column1,
        this.Column2});

        this.Column1.HeaderText = "Column1";
        this.Column1.Name = "Column1";

        this.Column2.HeaderText = "Column2";
        this.Column2.Name = "Column2";

I tried using the try{}catch{} method but it did not work for me. However, when I switched to using .then(...).catch(...), the AxiosError is caught correctly that I can play around with. When I try the former when putting a breakpoint, it does not allow me to see the AxiosError and instead, says to me that the caught error is undefined, which is also what eventually gets displayed in the UI.

Not sure why this happens I find it very trivial. Either way due to this, I suggest using the conventional .then(...).catch(...) method mentioned above to avoid throwing undefined errors to the user.

I'd just like to add a very simple example for testing this functionality on Windows:

Create the following two files and save them to a web directory:

foreground.php:

<?php

ini_set("display_errors",1);
error_reporting(E_ALL);

echo "<pre>loading page</pre>";

function run_background_process()
{
    file_put_contents("testprocesses.php","foreground start time = " . time() . "\n");
    echo "<pre>  foreground start time = " . time() . "</pre>";

    // output from the command must be redirected to a file or another output stream 
    // http://ca.php.net/manual/en/function.exec.php

    exec("php background.php > testoutput.php 2>&1 & echo $!", $output);

    echo "<pre>  foreground end time = " . time() . "</pre>";
    file_put_contents("testprocesses.php","foreground end time = " . time() . "\n", FILE_APPEND);
    return $output;
}

echo "<pre>calling run_background_process</pre>";

$output = run_background_process();

echo "<pre>output = "; print_r($output); echo "</pre>";
echo "<pre>end of page</pre>";
?>

background.php:

<?
file_put_contents("testprocesses.php","background start time = " . time() . "\n", FILE_APPEND);
sleep(10);
file_put_contents("testprocesses.php","background end time = " . time() . "\n", FILE_APPEND);
?>

Give IUSR permission to write to the directory in which you created the above files

Give IUSR permission to READ and EXECUTE C:\Windows\System32\cmd.exe

Hit foreground.php from a web browser

The following should be rendered to the browser w/the current timestamps and local resource # in the output array:

loading page
calling run_background_process
  foreground start time = 1266003600
  foreground end time = 1266003600
output = Array
(
    [0] => 15010
)
end of page

You should see testoutput.php in the same directory as the above files were saved, and it should be empty

You should see testprocesses.php in the same directory as the above files were saved, and it should contain the following text w/the current timestamps:

foreground start time = 1266003600
foreground end time = 1266003600
background start time = 1266003600
background end time = 1266003610

In the call back function, use the $request parameter

$parameters = $request->get_params();
echo $parameters['ppc'];

Class.cast() is rarely ever used in Java code. If it is used then usually with types that are only known at runtime (i.e. via their respective Class objects and by some type parameter). It is only really useful in code that uses generics (that's also the reason it wasn't introduced earlier).

It is not similar to reinterpret_cast, because it will not allow you to break the type system at runtime any more than a normal cast does (i.e. you can break generic type parameters, but can't break "real" types).

The evils of the C-style cast operator generally don't apply to Java. The Java code that looks like a C-style cast is most similar to a dynamic_cast<>() with a reference type in Java (remember: Java has runtime type information).

Generally comparing the C++ casting operators with Java casting is pretty hard since in Java you can only ever cast reference and no conversion ever happens to objects (only primitive values can be converted using this syntax).

Answer for Enterprise account with Xcode8

1. Export the .ipa by checking the "with manifest plist checkbox" and provide the links requested.

2. Upload the .ipa file and .plist file to the same location of the server (which you provided when exporting .ipa/ which mentioned in the .plist file).

3. Create the Download Link as given below. url should link to your .plist file location.

   itms-services://?action=download-manifest&url=https://yourdomainname.com/app.plist

4. Copy this link and paste it in safari browser in your iphone. It will ask to install :D

Create a html button using this full url

You can also use insertAdjacentHTML function:

const select = document.querySelector('select')
const value = 'bmw'
const label = 'BMW'

select.insertAdjacentHTML('beforeend', `
  <option value="${value}">${label}</option>
`)

Make sure you have all dependencies solved

I run into this problem in my first attempt at AOP, following a spring tutorial. My problem was not having spring-aop.jar in my classpath. The tutorial listed all other dependencies I had to add, namely:

• aspectjrt.jar
• aspectjweaver.jar
• aspectj.jar
• aopalliance.jar

But the one was missing. Just one more problem that can contribute to that symptom in the original question.

I am using Eclipse (neon), Java SE 8, beans 3.0, spring AOP 3.0, Spring 4.3.4. The problem showed in the Java view --not JEE--, and while trying to just run the application with Right button menu -> Run As -> Java Application.

Submodule repositories stay in a detached HEAD state pointing to a specific commit. Changing that commit simply involves checking out a different tag or commit then adding the change to the parent repository.

$ cd submodule
$ git checkout v2.0
Previous HEAD position was 5c1277e... bumped version to 2.0.5
HEAD is now at f0a0036... version 2.0

git-status on the parent repository will now report a dirty tree:

# On branch dev [...]
#
#   modified:   submodule (new commits)

Add the submodule directory and commit to store the new pointer.

JSON (= JavaScript Object Notation), is a lightweight and fast mechanism to convert Javascript objects into a string and vice versa.

Since Javascripts objects consists of key/value pairs its very easy to use and access JSON that way.

So if we have an object:

var myObj = {
    foo:   'bar',
    base:  'ball',
    deep:  {
       java:  'script'
    }
};

We can convert that into a string by calling window.JSON.stringify(myObj); with the result of "{"foo":"bar","base":"ball","deep":{"java":"script"}}".

The other way around, we would call window.JSON.parse("a json string like the above");.

JSON.parse() returns a javascript object/array on success.

alert(myObj.deep.java);  // 'script'

window.JSON is not natively available in all browser. Some "older" browser need a little javascript plugin which offers the above mentioned functionality. Check http://www.json.org for further information.

If your merge was not too complicated another option would be to:

1. Move all the changes including the merge changes back to stash using "git stash"
2. Run the merge again and commit your changes (without the changes from the dropped stash)
3. Run a "git stash pop" which should ignore all the changes from your previous merge since the files are identical now.

After that you are left with only the changes from the stash you dropped too early.

A Bin file is a pure binary file with no memory fix-ups or relocations, more than likely it has explicit instructions to be loaded at a specific memory address. Whereas....

ELF files are Executable Linkable Format which consists of a symbol look-ups and relocatable table, that is, it can be loaded at any memory address by the kernel and automatically, all symbols used, are adjusted to the offset from that memory address where it was loaded into. Usually ELF files have a number of sections, such as 'data', 'text', 'bss', to name but a few...it is within those sections where the run-time can calculate where to adjust the symbol's memory references dynamically at run-time.

I arrived at this question looking for a way to stream an open ended list of objects onto a System.IO.Stream and read them off the other end, without buffering the entire list before sending. (Specifically I'm streaming persisted objects from MongoDB over Web API.)

@Paul Tyng and @Rivers did an excellent job answering the original question, and I used their answers to build a proof of concept for my problem. I decided to post my test console app here in case anyone else is facing the same issue.

Note that you may receive an exception when the AnonymousPipeServerStream is disposed, I ignored this as it isn't relevant to the problem at hand.

You can convert char to int and viceversa easily because for the machine an int and a char are the same, 8 bits, the only difference comes when they have to be shown in screen, if the number is 65 and is saved as a char, then it will show 'A', if it's saved as a int it will show 65.

With other types things change, because they are stored differently in memory. There's standard function in C that allows you to convert from string to double easily, it's atof. (You need to include stdlib.h)

#include <stdlib.h>

int main()
{
    string word;  
    openfile >> word;
    double lol = atof(word.c_str()); /*c_str is needed to convert string to const char*
                                     previously (the function requires it)*/
    return 0;
}

Oddly it looks like the other two answers don't spell it out, and it's definitely worth saying:

i++ means 'tell me the value of i, then increment'

++i means 'increment i, then tell me the value'

They are Pre-increment, post-increment operators. In both cases the variable is incremented, but if you were to take the value of both expressions in exactly the same cases, the result will differ.

This is the right answer

preg_match("/^[0-9]+$/", $yourstr);

This function return TRUE(1) if it matches or FALSE(0) if it doesn't

Quick Explanation :

'^' : means that it should begin with the following ( in our case is a range of digital numbers [0-9] ) ( to avoid cases like ("abdjdf125") )

'+' : means there should be at least one digit

'$' : means after our pattern the string should end ( to avoid cases like ("125abdjdf") )

You can use:

GLfloat coordinates[8] = {1.0f, ..., 0.0f};

but this is a compile-time initialisation - you can't use that method in the current standard to re-initialise (although I think there are ways to do it in the upcoming standard, which may not immediately help you).

The other two ways that spring to mind are to blat the contents if they're fixed:

GLfloat base_coordinates[8] = {1.0f, ..., 0.0f};
GLfloat coordinates[8];
:
memcpy (coordinates, base_coordinates, sizeof (coordinates));

or provide a function that looks like your initialisation code anyway:

void setCoords (float *p0, float p1, ..., float p8) {
    p0[0] = p1; p0[1] = p2; p0[2] = p3; p0[3] = p4;
    p0[4] = p5; p0[5] = p6; p0[6] = p7; p0[7] = p8;
}
:
setCoords (coordinates, 1.0f, ..., 0.0f);

keeping in mind those ellipses (...) are placeholders, not things to literally insert in the code.

Well, to do this one can also use the freopen function provided in C++ - http://www.cplusplus.com/reference/cstdio/freopen/ and read the file line by line as follows -:

#include<cstdio>
#include<iostream>

using namespace std;

int main(){
   freopen("path to file", "rb", stdin);
   string line;
   while(getline(cin, line))
       cout << line << endl;
   return 0;
}

It's in fact almost the same in Python.. :-)

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

Of course, date doesn't have a time associated, so if you care about that too, you can do the same with a complete datetime object:

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

(Obviously no different, but you can store datetime.datetime.today() in a variable before you grab the year, of course).

One key thing to note is that the time components can differ between 32-bit and 64-bit pythons in some python versions (2.5.x tree I think). So you will find things like hour/min/sec on some 64-bit platforms, while you get hour/minute/second on 32-bit.

Some of these answers do work, but setting position: absolute; and z-index: 10; seemed pretty strong just to achieve the required effect. I found the following was all that was required, though unfortunately, I've not been able to reduce it any further.

HTML:

<div class="wrapper">
    <div class="parent">
        <div class="child">
            ...
        </div>
    </div>
</div>

CSS:

.wrapper {
    position: relative;
    z-index: 0;
}

.child {
    position: relative;
    z-index: -1;
}

I used this technique to achieve a bordered hover effect for image links. There's a bit more code here but it uses the concept above to show the border over the top of the image.

If you're still facing the issue even after replacing doGet() with doPost() and changing the form method="post". Try clearing the cache of the browser or hit the URL in another browser or incognito/private mode. It may works!

The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods

index.php

<html>
<body>

<form action="site2.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>

</body>
</html> 

site2.php

 <html>
 <body>

 Hello <?php echo $_POST["name"]; ?>!<br>
 Your mail is <?php echo $_POST["mail"]; ?>.

 </body>
 </html> 

output

Hello "name" !

Your email is "[email protected]" .

I had tried many different solutions. This was the only one that worked for me in that it was able to pick up on styles applied at class level and at style as directly attributed on the element. So a font set at css file level and one as a style attribute; it returned the correct font.

It is simple! (Sorry, can't find where I originally found it)

//-- html object
var element = htmlObject; //e.g document.getElementById
//-- or jquery object
var element = htmlObject[0]; //e.g $(selector)

var stylearray = document.defaultView.getComputedStyle(element, null);
var font = stylearray["font-family"]

Alternatively you can list all the style by cycling through the array

for (var key in stylearray) {
console.log(key + ': ' + stylearray[key];
}

u can do i hereString = hereString.replace(hereString.chatAt(hereString.length() - 1) ,' whitespeace');

This does what you want, and will work in nearly all cases:

>>> all(x in ['b', 'a', 'foo', 'bar'] for x in ['a', 'b'])
True

The expression 'a','b' in ['b', 'a', 'foo', 'bar'] doesn't work as expected because Python interprets it as a tuple:

>>> 'a', 'b'
('a', 'b')
>>> 'a', 5 + 2
('a', 7)
>>> 'a', 'x' in 'xerxes'
('a', True)

Other Options

There are other ways to execute this test, but they won't work for as many different kinds of inputs. As Kabie points out, you can solve this problem using sets...

>>> set(['a', 'b']).issubset(set(['a', 'b', 'foo', 'bar']))
True
>>> {'a', 'b'} <= {'a', 'b', 'foo', 'bar'}
True

...sometimes:

>>> {'a', ['b']} <= {'a', ['b'], 'foo', 'bar'}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

Sets can only be created with hashable elements. But the generator expression all(x in container for x in items) can handle almost any container type. The only requirement is that container be re-iterable (i.e. not a generator). items can be any iterable at all.

>>> container = [['b'], 'a', 'foo', 'bar']
>>> items = (i for i in ('a', ['b']))
>>> all(x in [['b'], 'a', 'foo', 'bar'] for x in items)
True

Speed Tests

In many cases, the subset test will be faster than all, but the difference isn't shocking -- except when the question is irrelevant because sets aren't an option. Converting lists to sets just for the purpose of a test like this won't always be worth the trouble. And converting generators to sets can sometimes be incredibly wasteful, slowing programs down by many orders of magnitude.

Here are a few benchmarks for illustration. The biggest difference comes when both container and items are relatively small. In that case, the subset approach is about an order of magnitude faster:

>>> smallset = set(range(10))
>>> smallsubset = set(range(5))
>>> %timeit smallset >= smallsubset
110 ns ± 0.702 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)
>>> %timeit all(x in smallset for x in smallsubset)
951 ns ± 11.5 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

This looks like a big difference. But as long as container is a set, all is still perfectly usable at vastly larger scales:

>>> bigset = set(range(100000))
>>> bigsubset = set(range(50000))
>>> %timeit bigset >= bigsubset
1.14 ms ± 13.9 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
>>> %timeit all(x in bigset for x in bigsubset)
5.96 ms ± 37 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Using subset testing is still faster, but only by about 5x at this scale. The speed boost is due to Python's fast c-backed implementation of set, but the fundamental algorithm is the same in both cases.

If your items are already stored in a list for other reasons, then you'll have to convert them to a set before using the subset test approach. Then the speedup drops to about 2.5x:

>>> %timeit bigset >= set(bigsubseq)
2.1 ms ± 49.2 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

And if your container is a sequence, and needs to be converted first, then the speedup is even smaller:

>>> %timeit set(bigseq) >= set(bigsubseq)
4.36 ms ± 31.4 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

The only time we get disastrously slow results is when we leave container as a sequence:

>>> %timeit all(x in bigseq for x in bigsubseq)
184 ms ± 994 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

And of course, we'll only do that if we must. If all the items in bigseq are hashable, then we'll do this instead:

>>> %timeit bigset = set(bigseq); all(x in bigset for x in bigsubseq)
7.24 ms ± 78 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

That's just 1.66x faster than the alternative (set(bigseq) >= set(bigsubseq), timed above at 4.36).

So subset testing is generally faster, but not by an incredible margin. On the other hand, let's look at when all is faster. What if items is ten-million values long, and is likely to have values that aren't in container?

>>> %timeit hugeiter = (x * 10 for bss in [bigsubseq] * 2000 for x in bss); set(bigset) >= set(hugeiter)
13.1 s ± 167 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
>>> %timeit hugeiter = (x * 10 for bss in [bigsubseq] * 2000 for x in bss); all(x in bigset for x in hugeiter)
2.33 ms ± 65.2 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Converting the generator into a set turns out to be incredibly wasteful in this case. The set constructor has to consume the entire generator. But the short-circuiting behavior of all ensures that only a small portion of the generator needs to be consumed, so it's faster than a subset test by four orders of magnitude.

This is an extreme example, admittedly. But as it shows, you can't assume that one approach or the other will be faster in all cases.

The Upshot

Most of the time, converting container to a set is worth it, at least if all its elements are hashable. That's because in for sets is O(1), while in for sequences is O(n).

On the other hand, using subset testing is probably only worth it sometimes. Definitely do it if your test items are already stored in a set. Otherwise, all is only a little slower, and doesn't require any additional storage. It can also be used with large generators of items, and sometimes provides a massive speedup in that case.

I found the answer here.

Use

sudo stop mysql

Actually it's possible, despite what's being said in other answers. If you have a FrameLayout, and want to position a child item to the bottom, you can use android:layout_gravity="bottom" and that is going to align that child to the bottom of the FrameLayout.

I know it works because I'm using it. I know is late, but it might come handy to others since this ranks in the top positions on google

Here's the list of all Win32 error codes. You can use this page to lookup the error code mentioned in IIS logs:
http://msdn.microsoft.com/en-us/library/ms681381.aspx

You can also use command line utility net to find information about a Win32 error code. The syntax would be:
net helpmsg Win32_Status_Code

Syntax is not a minor thing, it has a direct impact on how we think. It also has a direct effect on the rules we create for the systems we use. As an example we have the order of operations because of the way we write mathematical equations or sentences. The standard notation for mathematics allows people to read it more than one way and arrive at different answers given the same equation. If we had used prefix or postfix notation we would have created rules to distinguish what the numbers to be manipulated were rather than only having rules for the order in which to compute values.

The standard notation makes it plain what numbers we are talking about while making the order in which to compute them ambiguous. Prefix and postfix notation make the order in which to compute plain while making the numbers ambiguous. Python would already have multiline lambdas if it were not for the difficulties caused by the syntactic whitespace. (Proposals do exist for pulling this kind of thing off without necessarily adding explicit block delimiters.)

I find it easier to write conditions where I want something to occur if a condition is false much easier to write with the unless statement in Ruby than the semantically equivalent "if-not" construction in Ruby or other languages for example. If most of the languages that people are using today are equal in power, how can the syntax of each language be considered a trivial thing? After specific features like blocks and inheritance mechanisms etc. syntax is the most important part of a language,hardly a superficial thing.

What is superficial are the aesthetic qualities of beauty that we ascribe to syntax. Aesthetics have nothing to do with how our cognition works, syntax does.

You need to install the APK on the emulator. You can do this with the adb command line tool that is included in the Android SDK.

adb -e install -r yourapp.apk

Once you've done that you should be able to run the app.

The -e and -r flags might not be necessary. They just specify that you are using an emulator (if you also have a device connected) and that you want to replace the app if it already exists.

Maybe not what you want if you need to avoid hard-coding size values, but sometimes I use a "shim" (Separator) for this:

<Separator Width="42"></Separator>

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

Javascript does not have access to an image's individual pixel color data. At least, not maybe until html5 ... at which point it stands to reason that you'll be able to draw an image to a canvas, and then inspect the canvas (maybe, I've never done it myself).

Take a look at this tutorial for how to use SQL inside VBA:

http://www.ehow.com/how_7148832_access-vba-query-results.html

For a query that won't return results, use (reference here):

DoCmd.RunSQL

For one that will, use (reference here):

Dim dBase As Database
dBase.OpenRecordset

I actually use a makefile to build any dependencies needed before invoking devenv to build a particular project as in the following:

debug: coratools_debug
    devenv coralib.vcproj /build debug

coratools_debug: nothing
    cd ../coratools
    nmake debug
    cd $(MAKEDIR)

You can also use the msbuild tool to do the same thing:

debug: coratools_debug
    msbuild coralib.vcxproj /p:Configuration=debug

coratools_debug: nothing
    cd ../coratools
    nmake debug
    cd $(MAKEDIR)

In my opinion, this is much easier than trying to figure out the overly complicated visual studio project management scheme.

204 No Content

The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation. The response MAY include new or updated metainformation in the form of entity-headers, which if present SHOULD be associated with the requested variant.

According to the RFC part for the status code 204, it seems to me a valid choice for a GET request.

A 404 Not Found, 200 OK with empty body and 204 No Content have completely different meaning, sometimes we can't use proper status code but bend the rules and they will come back to bite you one day or later. So, if you can use proper status code, use it!

I think the choice of GET or POST is very personal as both of them will do the work but I would recommend you to keep a POST instead of a GET, for two reasons:

• You want the other part (the servlet if I understand correctly) to perform an action not retrieve some data from it.
• By default GET requests are cacheable if there are no parameters present in the URL, a POST is not.

macOS & Linux

BSD's find implementation on macOS is different from GNU find - this is compatible with both BSD and GNU find. Start with a globbing implementation, using -name and the -o for or - Put this function in your .bashrc file:

pyclean () {
    find . -type f -name '*.py[co]' -delete -o -type d -name __pycache__ -delete
}

Then cd to the directory you want to recursively clean, and type pyclean.

GNU find-only

This is a GNU find, only (i.e. Linux) solution, but I feel it's a little nicer with the regex:

pyclean () {
    find . -regex '^.*\(__pycache__\|\.py[co]\)$' -delete
}

Any platform, using Python 3

On Windows, you probably don't even have find. You do, however, probably have Python 3, which starting in 3.4 has the convenient pathlib module:

python3 -Bc "import pathlib; [p.unlink() for p in pathlib.Path('.').rglob('*.py[co]')]"
python3 -Bc "import pathlib; [p.rmdir() for p in pathlib.Path('.').rglob('__pycache__')]"

The -B flag tells Python not to write .pyc files. (See also the PYTHONDONTWRITEBYTECODE environment variable.)

The above abuses list comprehensions for looping, but when using python -c, style is rather a secondary concern. Alternatively we could abuse (for example) __import__:

python3 -Bc "for p in __import__('pathlib').Path('.').rglob('*.py[co]'): p.unlink()"
python3 -Bc "for p in __import__('pathlib').Path('.').rglob('__pycache__'): p.rmdir()"

Critique of an answer

The top answer used to say:

find . | grep -E "(__pycache__|\.pyc|\.pyo$)" | xargs rm -rf

This would seem to be less efficient because it uses three processes. find takes a regular expression, so we don't need a separate invocation of grep. Similarly, it has -delete, so we don't need a separate invocation of rm —and contrary to a comment here, it will delete non-empty directories so long as they get emptied by virtue of the regular expression match.

From the xargs man page:

find /tmp -depth -name core -type f -delete

Find files named core in or below the directory /tmp and delete them, but more efficiently than in the previous example (because we avoid the need to use fork(2) and exec(2) to launch rm and we don't need the extra xargs process).

Bootstrap 4 to hide whole content use this class '.d-none' it will be hide everything regardless of breakpoints same like previous bootstrap version class '.hidden'

I have also tried that error , I got it right by just adding /hello/any name because it is path that there must be an hello/name

example : instead of just putting http://localhost/app_dev.php

put it like this way http://localhost/name_of_your_project/web/app_dev.php/hello/ai

it will display Hello Ai . I hope I answer your question.

I had the same issue of WebMvcConfigurerAdapter being deprecated. When I searched for examples, I hardly found any implemented code. Here is a piece of working code.

create a class that extends HandlerInterceptorAdapter

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

import me.rajnarayanan.datatest.DataTestApplication;
@Component
public class EmployeeInterceptor extends HandlerInterceptorAdapter {
    private static final Logger logger = LoggerFactory.getLogger(DataTestApplication.class);
    @Override
    public boolean preHandle(HttpServletRequest request, 
            HttpServletResponse response, Object handler) throws Exception {

            String x = request.getMethod();
            logger.info(x + "intercepted");
        return true;
    }

}

then Implement WebMvcConfigurer interface

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

import me.rajnarayanan.datatest.interceptor.EmployeeInterceptor;
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
    @Autowired
    EmployeeInterceptor employeeInterceptor ;

    @Override
    public void addInterceptors(InterceptorRegistry registry){
        registry.addInterceptor(employeeInterceptor).addPathPatterns("/employee");
    }
}

There are synchronous action creators and then there are asynchronous action creators.

A synchronous action creator is one that when we call it, it immediately returns an Action object with all the relevant data attached to that object and its ready to be processed by our reducers.

Asynchronous action creators is one in which it will require a little bit of time before it is ready to eventually dispatch an action.

By definition, anytime you have an action creator that makes a network request, it is always going to qualify as an async action creator.

If you want to have asynchronous action creators inside of a Redux application you have to install something called a middleware that is going to allow you to deal with those asynchronous action creators.

You can verify this in the error message that tells us use custom middleware for async actions.

So what is a middleware and why do we need it for async flow in Redux?

In the context of redux middleware such as redux-thunk, a middleware helps us deal with asynchronous action creators as that is something that Redux cannot handle out of the box.

With a middleware integrated into the Redux cycle, we are still calling action creators, that is going to return an action that will be dispatched but now when we dispatch an action, rather than sending it directly off to all of our reducers, we are going to say that an action will be sent through all the different middleware inside the application.

Inside of a single Redux app, we can have as many or as few middleware as we want. For the most part, in the projects we work on we will have one or two middleware hooked up to our Redux store.

A middleware is a plain JavaScript function that will be called with every single action that we dispatch. Inside of that function a middleware has the opportunity to stop an action from being dispatched to any of the reducers, it can modify an action or just mess around with an action in any way you which for example, we could create a middleware that console logs every action you dispatch just for your viewing pleasure.

There are a tremendous number of open source middleware you can install as dependencies into your project.

You are not limited to only making use of open source middleware or installing them as dependencies. You can write your own custom middleware and use it inside of your Redux store.

One of the more popular uses of middleware (and getting to your answer) is for dealing with asynchronous action creators, probably the most popular middleware out there is redux-thunk and it is about helping you deal with asynchronous action creators.

There are many other types of middleware that also help you in dealing with asynchronous action creators.

i ran mvn generate-resources and then marked the /target/generated-resources folder as "sources" (Project Structure -> Project Settings -> Modules -> Select /target/generated-resources -> Click on blue "Sources" icon.

Check this find code for Database use:

function numonly(root){
    >>var reet = root.value;
    var arr1 = reet.length;
    var ruut = reet.charAt(arr1-1);
    >>>if (reet.length > 0){
        var regex = /[0-9]|\./;
        if (!ruut.match(regex)){
            var reet = reet.slice(0, -1);
            $(root).val(reet);
        >>>>}
    }
}
//Then use the even handler onkeyup='numonly(this)'

Try Using DateTime::createFromFormat

$date = DateTime::createFromFormat('d/m/Y', "24/04/2012");
echo $date->format('Y-m-d');

Output

2012-04-24

EDIT:

If the date is 5/4/2010 (both D/M/YYYY or DD/MM/YYYY), this below method is used to convert 5/4/2010 to 2010-4-5 (both YYYY-MM-DD or YYYY-M-D) format.

$old_date = explode('/', '5/4/2010'); 
$new_data = $old_date[2].'-'.$old_date[1].'-'.$old_date[0];

OUTPUT:

2010-4-5

Here is a link to various solutions of your issue.

This is my favorite as it makes the most human readable sense:

The Star Wildcard Method

if [[ "$string" == *"$substring"* ]]; then
    return 1
fi
return 0

I found a better library which transform the normal <select> <option> to bootsrap button dropdown format.

https://developer.snapappointments.com/bootstrap-select/

Since I happened to be working on this also, and was looking around for any ideas, this is the solution I came to. It uses LINQ, and will be able to capitalize the first letter of a string, even if the first occurrence isn't a letter. Here's the extension method I ended up making.

public static string CaptalizeFirstLetter(this string data)
{
    var chars = data.ToCharArray();

    // Find the Index of the first letter
    var charac = data.First(char.IsLetter);
    var i = data.IndexOf(charac);

    // capitalize that letter
    chars[i] = char.ToUpper(chars[i]);

    return new string(chars);
}

I'm sure there's a way to optimize or clean this up a little bit.

You can use the Window object and access it everwhere. example window.defaultTitle = "my title"; then you can access window.defaultTitle without importing anything.

Create this function prototype:

Array.prototype.contains = function ( needle ) {
   for (i in this) {
      if (this[i] == needle) return true;
   }
   return false;
}

and then you can use following code to search in array x

if (x.contains('searchedString')) {
    // do a
}
else
{
      // do b
}

In short,

Struts is for Front-end development of website

Hibernate is for back-end development of website

Spring is for full stack development of website in which Spring MVC(Model-View-Controller) is for Front-end. ORM, JDBC for Data Access / Integration(backend). etc

Here's another solution, usable if the frames are from different domains.

var frame = /*the iframe DOM object*/;
frame.contentWindow.postMessage({call:'sendValue', value: /*value*/}, /*frame domain url or '*'*/);

And in the frame itself:

window.addEventListener('message', function(event) {
    var origin = event.origin || event.originalEvent.origin; // For Chrome, the origin property is in the event.originalEvent object.
    if (origin !== /*the container's domain url*/)
        return;
    if (typeof event.data == 'object' && event.data.call=='sendValue') {
        // Do something with event.data.value;
    }
}, false);

Don't know which browsers support this, though.

I am not sure about Python but most languages have push/append function for arrays.

You can also use myform.$invalid

E.g.

if($scope.myform.$invalid){return;}

In powershell 5.1 you can actually use install-package, but it can't take extra msi arguments.

install-package .\file.msi

Otherwise with start-process and waiting:

start -wait file.msi ALLUSERS=1,INSTALLDIR=C:\FILE

You can directly plot the lines you want by feeding the plot command with the corresponding data (boundaries of the segments):

plot([x1, x2], [y1, y2], color='k', linestyle='-', linewidth=2)

(of course you can choose the color, line width, line style, etc.)

From your example:

import numpy as np
import matplotlib.pyplot as plt

np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")


# draw vertical line from (70,100) to (70, 250)
plt.plot([70, 70], [100, 250], 'k-', lw=2)

# draw diagonal line from (70, 90) to (90, 200)
plt.plot([70, 90], [90, 200], 'k-')

plt.show()

Java Strings aren't character Iterable. You'll need:

for (int i = 0; i < examplestring.length(); i++) {
  char c = examplestring.charAt(i);
  ...
}

Awkward I know.

In my case, I had to change the cell padding of an element that contained an input checkbox for a table that's being dynamically rendered with DataTables:

<td class="dt-center">
    <input class="a" name="constCheck" type="checkbox" checked="">
</td>

After implementing the following line code within the initComplete function I was able to produce the correct padding, which fixed the rows from being displayed with an abnormally large height

 $('tbody td:has(input.a)').css('padding', '0px');

Now, you can see that the correct styles are being applied to the parent element:

<td class=" dt-center" style="padding: 0px;">
    <input class="a" name="constCheck" type="checkbox" checked="">
</td>

Essentially, this answer is an extension of @KP's answer, but the more collaboration of implementing this the better. In summation, I hope this helps someone else because it works! Lastly, thank you so much @KP for leading me in the right direction!

This eclipse documentation has details on the markups in .project file: The project description file

It describes the .project file as:

When a project is created in the workspace, a project description file is automatically generated that describes the project. The purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace. This file is always called ".project"

Here is the perfect method:

Please note that Environment.NewLine works on on Microsoft platforms.

In addition to the above, you need to add \r and \n in a separate function!

Here is the code which will support whether you type on Linux, Windows, or Mac:

var stringTest = "\r Test\nThe Quick\r\n brown fox";

Console.WriteLine("Original is:");
Console.WriteLine(stringTest);
Console.WriteLine("-------------");

stringTest = stringTest.Trim().Replace("\r", string.Empty);
stringTest = stringTest.Trim().Replace("\n", string.Empty);
stringTest = stringTest.Replace(Environment.NewLine, string.Empty);

Console.WriteLine("Output is : ");
Console.WriteLine(stringTest);
Console.ReadLine();

I would recommend the first option, where you actually build elements using jQuery. the second approach simply sets the innerHTML property of the element to a string, which happens to be HTML, and is more error prone and less flexible.

In my case, 8080 is the port I want to kill
And 18264 is the PID listening on port 8080
So the task you have to kill is the PID for that particular port

C:\Users\Niroshan>netstat -ano|findstr "PID :8080"

Proto Local Address Foreign Address State PID
TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 18264

taskkill /PID 18264 /f

You need to:

unbind('scroll')

At the moment you are not specifying the event to unbind.

I would do like this:

String title_part = "title part1.txt";
int i;
for(i=title_part.length()-1 ; i>=0 && title_part.charAt(i)!='.' ; i--);
title_part = title_part.substring(0,i);

Starting to the end till the '.' then call substring.

You cannot find it. It is stored in a database, which you need the root password to access, and even if you did get access somehow, it is hashed with a one-way hash. You can reset it: http://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html

<ScrollViewer MaxHeight="50"

I am doing this in another way by putting MaxHeight in ScrollViewer.

Just Adjust the MaxHeight to show more or fewer lines of text. Easy.

By default CM10 only allows root access from Apps not ADB. Go to Settings -> Developer options -> Root access, and change option to "Apps and ADB".

If you are working on your own, and you want the closest thing to OOP as you would find in Java or C# or C++, see the javascript library, CrxOop. CrxOop provides syntax somewhat familiar to Java developers.

Just be careful, Java's OOP is not the same as that found in Javascript. To get the same behavior as in Java, use CrxOop's classes, not CrxOop's structures, and make sure all your methods are virtual. An example of the syntax is,

crx_registerClass("ExampleClass", 
{ 
    "VERBOSE": 1, 

    "public var publicVar": 5, 
    "private var privateVar": 7, 

    "public virtual function publicVirtualFunction": function(x) 
    { 
        this.publicVar1 = x;
        console.log("publicVirtualFunction"); 
    }, 

    "private virtual function privatePureVirtualFunction": 0, 

    "protected virtual final function protectedVirtualFinalFunction": function() 
    { 
        console.log("protectedVirtualFinalFunction"); 
    }
}); 

crx_registerClass("ExampleSubClass", 
{ 
    VERBOSE: 1, 
    EXTENDS: "ExampleClass", 

    "public var publicVar": 2, 

    "private virtual function privatePureVirtualFunction": function(x) 
    { 
        this.PARENT.CONSTRUCT(pA);
        console.log("ExampleSubClass::privatePureVirtualFunction"); 
    } 
}); 

var gExampleSubClass = crx_new("ExampleSubClass", 4);

console.log(gExampleSubClass.publicVar);
console.log(gExampleSubClass.CAST("ExampleClass").publicVar);

The code is pure javascript, no transpiling. The example is taken from a number of examples from the official documentation.

ContainsKey is what you're looking for.

I used to have the same problem.

Your config use security="none" so cannot generate _csrf:

<http pattern="/login.jsp" security="none"/>

you can set access="IS_AUTHENTICATED_ANONYMOUSLY" for page /login.jsp replace above config:

<http>
    <intercept-url pattern="/login.jsp*" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
    <intercept-url pattern="/**" access="ROLE_USER"/>
    <form-login login-page="/login.jsp"
            authentication-failure-url="/login.jsp?error=1"
            default-target-url="/index.jsp"/>
    <logout/>
    <csrf />
</http>
