"Dino TW" has provided the link to the comment Hibernate Mapping Exception : Repeated column in mapping for entity which has the vital information.

The link hints to provide "inverse=true" in the set mapping, I tried it and it actually works. It is such a rare situation wherein a Set and Composite key come together. Make inverse=true, we leave the insert & update of the table with Composite key to be taken care by itself.

Below can be the required mapping,

<class name="com.example.CompanyEntity" table="COMPANY">
    <id name="id" column="COMPANY_ID"/>
    <set name="names" inverse="true" table="COMPANY_NAME" cascade="all-delete-orphan" fetch="join" batch-size="1" lazy="false">
        <key column="COMPANY_ID" not-null="true"/>
        <one-to-many entity-name="vendorName"/>
    </set>
</class>

Re: SQL DevErr:The Network Adapter could not establish the connection VenCode20 Posted: Dec 7, 2011 3:23 AM in response to: MehulDoshi Reply

This worked for me:

Open the "New/Select Database Connection" dialogue and try changing the connection type setting from "Basic" to "TNS" and then selecting the network alias (for me: "ORCL").

var app = angular.module('myApp', [])

app.controller('MainCtrl', ['$scope', function($scope){
   $scope.num1 = 1;
   $scope.num2 = 1;
   $scope.total = parseInt($scope.num1 + $scope.num2);

}]);

Demo: parseInt with AngularJS

I would just not add it in the first place:

 var sb = new StringBuilder();

 bool first = true;
 foreach (var foo in items) {
    if (first)
        first = false;
    else
        sb.Append('&');

    // for example:
    var escapedValue = System.Web.HttpUtility.UrlEncode(foo);

    sb.Append(key).Append('=').Append(escapedValue);
 }

 var s = sb.ToString();

Use the debug lib.

import debug from 'debug'
const log = debug('server');

Use it:

log('holi')

then run:

DEBUG=server npm test

And that's it!

Seems pretty straightforward, according to the docs on the page you linked (emphasis mine).

requests.get(url, params=None, headers=None, cookies=None, auth=None, timeout=None)

Sends a GET request. Returns Response object.

Parameters:

• url – URL for the new Request object.
• params – (optional) Dictionary of GET Parameters to send with the Request.
• headers – (optional) Dictionary of HTTP Headers to send with the Request.
• cookies – (optional) CookieJar object to send with the Request.
• auth – (optional) AuthObject to enable Basic HTTP Auth.
• timeout – (optional) Float describing the timeout of the request.

If you are Bangladeshi, and if you want to get the time of Dhaka then use this:

$date = new DateTime();
$date->setTimeZone(new DateTimeZone("Asia/Dhaka"));
$get_datetime = $date->format('d.m.Y H:i:s');

Both if (one.length() > 0) {} and if (!"".equals(one)) {} will check against an empty foo parameter, and an empty parameter is what you'd get if the the form is submitted with no value in the foo text field.

If there's any chance you can use the Expression Language to handle the parameter, you could access it with empty param.foo in an expression.

<c:if test='${not empty param.foo}'>
    This page code gets rendered.
</c:if>

You can:

SELECT CR 
FROM table1 
WHERE len(CR) = (SELECT max(len(CR)) FROM table1)

Having just recieved an upvote more than a year after posting this, I'd like to add some information.

• This query gives all values with the maximum length. With a TOP 1 query you get only one of these, which is usually not desired.
• This query must probably read the table twice: a full table scan to get the maximum length and another full table scan to get all values of that length. These operations, however, are very simple operations and hence rather fast. With a TOP 1 query a DBMS reads all records from the table and then sorts them. So the table is read only once, but a sort operation on a whole table is quite some task and can be very slow on large tables.
• One would usually add DISTINCT to my query (SELECT DISTINCT CR FROM ...), so as to get every value just once. That would be a sort operation, but only on the few records already found. Again, no big deal.
• If the string lengths have to be dealt with quite often, one might think of creating a computed column (calculated field) for it. This is available as of Ms Access 2010. But reading up on this shows that you cannot index calculated fields in MS Access. As long as this holds true, there is hardly any benefit from them. Applying LEN on the strings is usually not what makes such queries slow.

Note that you can deploy remotely using HTTP.

http://localhost:8080/manager/deploy

Upload the web application archive (WAR) file that is specified as the request data in this HTTP PUT request, install it into the appBase directory of our corresponding virtual host, and start it using the war file name without the .war extension as the path. The application can later be undeployed (and the corresponding application directory removed) by use of the /undeploy. To deploy the ROOT web application (the application with a context path of "/"), name the war ROOT.war.

and if you're using Ant you can do this using Tomcat Ant tasks (perhaps following a successful build).

To determine which path you then hit on your browser, you need to know the port Tomcat is running on, the context and your servlet path. See here for more details.

If you want to test explicitly for valid JSON (as opposed to the absence of the returned value false), then you can use a parsing approach as described here.

A BLOB can be 65535 bytes (64 KB) maximum.

If you need more consider using:

• a MEDIUMBLOB for 16777215 bytes (16 MB)

• a LONGBLOB for 4294967295 bytes (4 GB).

See Storage Requirements for String Types for more info.

I find it easier to remember to just read it and then write it.

For example:

with open('file') as f:
    data = f.read()
with open('file', 'w') as f:
    f.write('hello')

When you do new Promise((resolve)... the type inferred was Promise<{}> because you should have used new Promise<number>((resolve).

It is interesting that this issue was only highlighted when the async keyword was added. I would recommend reporting this issue to the TS team on GitHub.

There are many ways you can get around this issue. All the following functions have the same behavior:

const whatever1 = () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever2 = async () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever3 = async () => {
    return await new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever4 = async () => {
    return Promise.resolve(4);
};

const whatever5 = async () => {
    return await Promise.resolve(4);
};

const whatever6 = async () => Promise.resolve(4);

const whatever7 = async () => await Promise.resolve(4);

In your IDE you will be able to see that the inferred type for all these functions is () => Promise<number>.

I've had luck starting chrome with the following switch:

--allow-file-access-from-files

On os x try (re-type the dashes if you copy paste):

open -a 'Google Chrome' --args -allow-file-access-from-files

On other *nix run (not tested)

 google-chrome  --allow-file-access-from-files

or on windows edit the properties of the chrome shortcut and add the switch, e.g.

 C:\ ... \Application\chrome.exe --allow-file-access-from-files

to the end of the "target" path

The header just denotes what the content is encoded in. It is not necessarily possible to deduce the type of the content from the content itself, i.e. you can't necessarily just look at the content and know what to do with it. That's what HTTP headers are for, they tell the recipient what kind of content they're (supposedly) dealing with.

Content-type: application/json; charset=utf-8 designates the content to be in JSON format, encoded in the UTF-8 character encoding. Designating the encoding is somewhat redundant for JSON, since the default (only?) encoding for JSON is UTF-8. So in this case the receiving server apparently is happy knowing that it's dealing with JSON and assumes that the encoding is UTF-8 by default, that's why it works with or without the header.

Does this encoding limit the characters that can be in the message body?

No. You can send anything you want in the header and the body. But, if the two don't match, you may get wrong results. If you specify in the header that the content is UTF-8 encoded but you're actually sending Latin1 encoded content, the receiver may produce garbage data, trying to interpret Latin1 encoded data as UTF-8. If of course you specify that you're sending Latin1 encoded data and you're actually doing so, then yes, you're limited to the 256 characters you can encode in Latin1.

This should solve your problem, you should try to run the following below:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser 

As far as I read manual pages, scanf says that 'l' length modifier indicates (in case of floating points) that the argument is of type double rather than of type float, so you can have 'lf, le, lg'.

As for printing, officially, the manual says that 'l' applies only to integer types. So it might be not supported on some systems or by some standards. For instance, I get the following error message when compiling with gcc -Wall -Wextra -pedantic

a.c:6:1: warning: ISO C90 does not support the ‘%lf’ gnu_printf format [-Wformat=]

So you may want to doublecheck if your standard supports the syntax.

To conclude, I would say that you read with '%lf' and you print with '%f'.

I have just used dompdf and the code was a little different but it worked.

Here it is:

require_once("./pdf/dompdf_config.inc.php");
$files = glob("./pdf/include/*.php");
foreach($files as $file) include_once($file);

$html =
      '<html><body>'.
      '<p>Put your html here, or generate it with your favourite '.
      'templating system.</p>'.
      '</body></html>';

    $dompdf = new DOMPDF();
    $dompdf->load_html($html);
    $dompdf->render();
    $output = $dompdf->output();
    file_put_contents('Brochure.pdf', $output);

Only difference here is that all of the files in the include directory are included.

Other than that my only suggestion would be to specify a full directory path for writing the file rather than just the filename.

Since you haven't given table definitions, it's hard to guess. But it looks like you are attempting to modify the foreign key in the child table. AFAIK, this is illegal, you can modify it from the parent, but not the child table.

Consider this example:

CREATE TABLE parent (
  parent_id INT NOT NULL,
  parent_data int,

  PRIMARY KEY (parent_id)
) ENGINE=INNODB;

CREATE TABLE child1 (
  child1_id INT,
  child1_data INT,
  fk_parent_id INT,

  INDEX par_ind1 (fk_parent_id),

  FOREIGN KEY (fk_parent_id)
    REFERENCES parent(parent_id)
    ON DELETE CASCADE
    ON UPDATE CASCADE
) ENGINE=INNODB;

CREATE TABLE child2 (
  child2_id INT,
  child2_data INT,
  fk_parent_id INT,

  INDEX par_ind2 (fk_parent_id),

  FOREIGN KEY (fk_parent_id)
    REFERENCES parent(parent_id)
    ON DELETE CASCADE
    ON UPDATE CASCADE
) ENGINE=INNODB;

INSERT INTO parent
  (parent_id, parent_data)
  VALUES
  (1, 11),
  (2, 12);

INSERT INTO child1
  (child1_id, child1_data, fk_parent_id)
  VALUES
  (101, 1001, 1),
  (102, 1002, 1),
  (103, 1003, 1),
  (104, 1004, 2),
  (105, 1005, 2);

INSERT INTO child2
  (child2_id, child2_data, fk_parent_id)
  VALUES
  (106, 1006, 1),
  (107, 1007, 1),
  (108, 1008, 1),
  (109, 1009, 2),
  (110, 1010, 2);

Then this is allowed:

UPDATE parent
  SET parent_id = 3 WHERE parent_id = 2;

SELECT * FROM parent;
SELECT * FROM child1;
SELECT * FROM child2;

But this is not, because it modifies the parent fk from the child table:

UPDATE child1
  SET fk_parent_id = 4 WHERE fk_parent_id = 1;

It gets an error very similar to your error:

Cannot add or update a child row: a foreign key constraint fails (`db_2_b43a7`.`child1`, CONSTRAINT `child1_ibfk_1` FOREIGN KEY (`fk_parent_id`) REFERENCES `parent` (`parent_id`) ON DELETE CASCADE ON UPDATE CASCADE):

I believe .clone() is what you're looking for, so long as the class supports it.

Add -R for recursive:

I guess you may have already found the answer, but if not (and for other developers), you can do it like this:

btnMybutton.getBackground().setAlpha(45);

Here I have set the opacity to 45. You can basically set it from anything between 0(fully transparent) to 255 (completely opaque)

#include <file> 

Includes a file where the default include directory is.

#include "file" 

Includes a file in the current directory in which it was compiled.

More things can be done with keyboard module. You can install this module using pip install keyboard Here are some of the methods:

Method #1:

Using the function read_key():

import keyboard

while True:
    if keyboard.read_key() == "p":
        print("You pressed p")
        break

This is gonna break the loop as the key p is pressed.

Method #2:

Using function wait:

import keyboard

keyboard.wait("p")
print("You pressed p")

It will wait for you to press p and continue the code as it is pressed.

Method #3:

Using the function on_press_key:

import keyboard

keyboard.on_press_key("p", lambda _:print("You pressed p"))

It needs a callback function. I used _ because the keyboard function returns the keyboard event to that function.

Once executed, it will run the function when the key is pressed. You can stop all hooks by running this line:

keyboard.unhook_all()

Method #4:

This method is sort of already answered by user8167727 but I disagree with the code they made. It will be using the function is_pressed but in an other way:

import keyboard

while True:
    if keyboard.is_pressed("p"):
        print("You pressed p")
        break

It will break the loop as p is pressed.

Notes:

• keyboard will read keypresses from the whole OS.
• keyboard requires root on linux

1. Check the latest Jest (v 0.22): https://github.com/facebook/jest

2. The Facebook team adds the Istanbul code coverage output as part of the coverage report and you can use it directly.

3. After executing Jest, you can get a coverage report in the console and under the root folder set by Jest, you will find the coverage report in JSON and HTML format.

4. FYI, if you install from npm, you might not get the latest version; so try the GitHub first and make sure the coverage is what you need.

Use java.sql.Timestamp.toString if you want to get fractional seconds in text representation. The difference betwen Timestamp from DB and Java Date is that DB precision is nanoseconds while Java Date precision is milliseconds.

Extending @Ryogi answer above, you can take advantage of the lower.tail parameter like so:

qt(0.25/2, 40, lower.tail = FALSE) # 75% confidence

qt(0.01/2, 40, lower.tail = FALSE) # 99% confidence

Don't forget that, even though tabindex is all lowercase in the specs and in the HTML, in Javascript/the DOM that property is called tabIndex.

Don't lose your mind trying to figure out why your programmatically altered tab indices calling element.tabindex = -1 isn't working. Use element.tabIndex = -1.

Based on this blog, one could share a docker image without a docker registry by executing:

docker save --output latestversion-1.0.0.tar dockerregistry/latestversion:1.0.0

Once this command has been completed, one could copy the image to a server and import it as follows:

docker load --input latestversion-1.0.0.tar

Your JSON-data contains the property Data, but you're accessing data. It's case sensitive

            document.myform.result1.value = result;
        },
    });
}        

EDIT Also City and Code is in the wrong case. (Thanks @Christopher Kenney)

EDIT2 It should also be json, and not jsonp (at least in this case)

UPDATE According to your latest comment, you should read this answer: https://stackoverflow.com/a/11736771/325836 by Abdul Munim

Best general purpose - Especially short arrays (1000 items or less) and coders that are unsure of what optimizations best suit their needs.

# $value can be any regex. be safe
if ( grep( /^$value$/, @array ) ) {
  print "found it";
}

It has been mentioned that grep passes through all values even if the first value in the array matches. This is true, however grep is still extremely fast for most cases. If you're talking about short arrays (less than 1000 items) then most algorithms are going to be pretty fast anyway. If you're talking about very long arrays (1,000,000 items) grep is acceptably quick regardless of whether the item is the first or the middle or last in the array.

Optimization Cases for longer arrays:

If your array is sorted, use a "binary search".

If the same array is repeatedly searched many times, copy it into a hash first and then check the hash. If memory is a concern, then move each item from the array into the hash. More memory efficient but destroys the original array.

If same values are searched repeatedly within the array, lazily build a cache. (as each item is searched, first check if the search result was stored in a persisted hash. if the search result is not found in the hash, then search the array and put the result in the persisted hash so that next time we'll find it in the hash and skip the search).

Note: these optimizations will only be faster when dealing with long arrays. Don't over optimize.

Here is a simple one liner function

//ECHMA5
function GetMonth(anyDate) { 
   return 'Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec'.split(',')[anyDate.getMonth()];
 }
//
// ECMA6
var GetMonth = (anyDate) => 'Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec'.split(',')[anyDate.getMonth()];

To me, it is better to put the transition codes with the original/minimum selectors than with the :hover or any other additional selectors:

#content #nav a {_x000D_
    background-color: #FF0;_x000D_
    _x000D_
    -webkit-transition: background-color 1000ms linear;_x000D_
    -moz-transition: background-color 1000ms linear;_x000D_
    -o-transition: background-color 1000ms linear;_x000D_
    -ms-transition: background-color 1000ms linear;_x000D_
    transition: background-color 1000ms linear;_x000D_
}_x000D_
_x000D_
#content #nav a:hover {_x000D_
    background-color: #AD310B;_x000D_
}

<div id="content">_x000D_
    <div id="nav">_x000D_
        <a href="#link1">Link 1</a>_x000D_
    </div>_x000D_
</div>

rebooting the machine was the only thing that worked for me

I'm showing this for the latest access time, and you can easily modify this to do latest modification time.

There are two ways to do this:

1. If you want to avoid global sorting which can be expensive if you have tens of millions of files, then you can do (position yourself in the root of the directory where you want your search to start):

    Linux> touch -d @0 /tmp/a;
    Linux> find . -type f -exec tcsh -f -c test `stat --printf="%X" {}` -gt  `stat --printf="%X" /tmp/a`  ; -exec tcsh -f -c touch -a -r {} /tmp/a ; -print
   

   The above method prints filenames with progressively newer access time and the last file it prints is the file with the latest access time. You can obviously get the latest access time using a "tail -1".

2. You can have find recursively print the name and access time of all files in your subdirectory and then sort based on access time and the tail the biggest entry:

    Linux> \find . -type f -exec stat --printf="%X  %n\n" {} \; | \sort -n | tail -1
   

And there you have it...

I took code from dofactory.com, nothing so fancy but I find this far good than examples with Foo and Bar additionally book from Judith Bishop on C# 3.0 Design Patterns has example about active application in mac dock.

If you look at code we are actually building new objects on for loop, so that creates new object but reuses instance as a result of which the oldbalancer and newbalancer has same instance, How? its due to static keyword used on function GetLoadBalancer(), despite of having different server value which is random list, static on GetLoadBalancer() belongs to the type itself rather than to a specific object.

Additionally there is double check locking here

if (_instance == null)
            {
                lock (syncLock)
                {
                    if (_instance == null)

since from MSDN

The lock keyword ensures that one thread does not enter a critical section of code while another thread is in the critical section. If another thread tries to enter a locked code, it will wait, block, until the object is released.

so every-time mutual-exclusion lock is issued, even if it don't need to which is unnecessary so we have null check.

Hopefully it helps in clearing more.

And please comment if I my understanding is directing wrong ways.

Yes, set the cell as a RANGE object one time and then use that RANGE object in your code:

Sub RangeExample()
Dim MyRNG As Range

Set MyRNG = Sheets("Sheet1").Cells(23, 4)

Debug.Print MyRNG.Value

End Sub

Alternately you can simply store the value of that cell in memory and reference the actual value, if that's all you really need. That variable can be Long or Double or Single if numeric, or String:

Sub ValueExample()
Dim MyVal As String

MyVal = Sheets("Sheet1").Cells(23, 4).Value

Debug.Print MyVal

End Sub

For just reading file and outputting it the best one would be readfile.

Most times SDL is in /usr/include/SDL. If so then your #include <SDL.h> directive is wrong, it should be #include <SDL/SDL.h>.

An alternative for that is adding the /usr/include/SDL directory to your include directories. To do that you should add -I/usr/include/SDL to the compiler flags...

If you are using an IDE this should be quite easy too...

(1) Use str.isalpha() when you print the string.

(2) Please check below program for your reference:-

 str = "this";  # No space & digit in this string
 print str.isalpha() # it gives return True

 str = "this is 2";
 print str.isalpha() # it gives return False

Note:- I checked above example in Ubuntu.

My solution in Header parameters with example is user="test" is:

@RequestMapping(value = "/restURL")
  public String serveRest(@RequestBody String body, @RequestHeader HttpHeaders headers){

System.out.println(headers.get("user"));
}

Drop the parentheses and commas:

 myBackupFunction ".." "..." "xx"

And the function should look like this:

function myBackupFunction() {
    # Here $1 is the first parameter, $2 the second, etc.

I haven't played around with it much but eclipse/pydev feels nice.

You can try to do this:

...
// get completed xml document
$doc->preserveWhiteSpace = false;
$doc->formatOutput = true;
$xml_string = $doc->saveXML();
echo $xml_string;

You can make set these parameter right after you've created the DOMDocument as well:

$doc = new DomDocument('1.0');
$doc->preserveWhiteSpace = false;
$doc->formatOutput = true;

That's probably more concise. Output in both cases is (Demo):

<?xml version="1.0"?>
<root>
  <error>
    <a>eee</a>
    <b>sd</b>
    <c>df</c>
  </error>
  <error>
    <a>eee</a>
    <b>sd</b>
    <c>df</c>
  </error>
  <error>
    <a>eee</a>
    <b>sd</b>
    <c>df</c>
  </error>
</root>

I'm not aware how to change the indentation character(s) with DOMDocument. You could post-process the XML with a line-by-line regular-expression based replacing (e.g. with preg_replace):

$xml_string = preg_replace('/(?:^|\G)  /um', "\t", $xml_string);

Alternatively, there is the tidy extension with tidy_repair_string which can pretty print XML data as well. It's possible to specify indentation levels with it, however tidy will never output tabs.

tidy_repair_string($xml_string, ['input-xml'=> 1, 'indent' => 1, 'wrap' => 0]);

{{ dump() }} doesn't work for me. PHP chokes. Nesting level too deep I guess.

All you really need to debug Twig templates if you're using a debugger is an extension like this.

Then it's just a matter of setting a breakpoint and calling {{ inspect() }} wherever you need it. You get the same info as with {{ dump() }} but in your debugger.

All algorithms can be defined recursively. That makes it much, much easier to visualize and prove.

Some algorithms (e.g., the Ackermann Function) cannot (easily) be specified iteratively.

A recursive implementation will use more memory than a loop if tail call optimization can't be performed. While iteration may use less memory than a recursive function that can't be optimized, it has some limitations in its expressive power.

np.where returns a tuple of length equal to the dimension of the numpy ndarray on which it is called (in other words ndim) and each item of tuple is a numpy ndarray of indices of all those values in the initial ndarray for which the condition is True. (Please don't confuse dimension with shape)

For example:

x=np.arange(9).reshape(3,3)
print(x)
array([[0, 1, 2],
      [3, 4, 5],
      [6, 7, 8]])
y = np.where(x>4)
print(y)
array([1, 2, 2, 2], dtype=int64), array([2, 0, 1, 2], dtype=int64))

y is a tuple of length 2 because x.ndim is 2. The 1st item in tuple contains row numbers of all elements greater than 4 and the 2nd item contains column numbers of all items greater than 4. As you can see, [1,2,2,2] corresponds to row numbers of 5,6,7,8 and [2,0,1,2] corresponds to column numbers of 5,6,7,8 Note that the ndarray is traversed along first dimension(row-wise).

Similarly,

x=np.arange(27).reshape(3,3,3)
np.where(x>4)

will return a tuple of length 3 because x has 3 dimensions.

But wait, there's more to np.where!

when two additional arguments are added to np.where; it will do a replace operation for all those pairwise row-column combinations which are obtained by the above tuple.

x=np.arange(9).reshape(3,3)
y = np.where(x>4, 1, 0)
print(y)
array([[0, 0, 0],
   [0, 0, 1],
   [1, 1, 1]])

I had the same question. This works great in Wordpress!

Any time you cannot have iterators invalidated.

On your remote machine, System.Data.OracleClient need access to some of the oracle dll which are not part of .Net. Solutions:

• Install Oracle Client , and add bin location to Path environment varaible of windows OR
• Copy oraociicus10.dll (Basic-Lite version) or aociei10.dll (Basic version), oci.dll, orannzsbb10.dll and oraocci10.dll from oracle client installable folder to bin folder of application so that application is able to find required dll

On your local machine most probably path to Oracle Client is already added in Path environment variable to there required dll are available to application but not on remote machine

You can use stuff and patindex.

stuff(Col, 1, patindex('%[0-9]%', Col)-1, '')

SQL Fiddle

Felix already provided an excellent answer, but I thought I'd do a speed comparison of the various methods:

1. 10.59 sec (105.9us/itn) - copy.deepcopy(old_list)
2. 10.16 sec (101.6us/itn) - pure python Copy() method copying classes with deepcopy
3. 1.488 sec (14.88us/itn) - pure python Copy() method not copying classes (only dicts/lists/tuples)
4. 0.325 sec (3.25us/itn) - for item in old_list: new_list.append(item)
5. 0.217 sec (2.17us/itn) - [i for i in old_list] (a list comprehension)
6. 0.186 sec (1.86us/itn) - copy.copy(old_list)
7. 0.075 sec (0.75us/itn) - list(old_list)
8. 0.053 sec (0.53us/itn) - new_list = []; new_list.extend(old_list)
9. 0.039 sec (0.39us/itn) - old_list[:] (list slicing)

So the fastest is list slicing. But be aware that copy.copy(), list[:] and list(list), unlike copy.deepcopy() and the python version don't copy any lists, dictionaries and class instances in the list, so if the originals change, they will change in the copied list too and vice versa.

(Here's the script if anyone's interested or wants to raise any issues:)

You need to use preventDefault() to make it so the link does not go through when u click on it:

fiddle: http://jsfiddle.net/maniator/Sevdm/

$(function() {
 $('.menulink').click(function(e){
     e.preventDefault();
   $("#bg").attr('src',"img/picture1.jpg");
 });
});

The query should be:

(&(objectCategory=user)(memberOf=CN=Distribution Groups,OU=Mybusiness,DC=mydomain.local,DC=com))

You missed & and ()

To generate a number between 10 to 20 inclusive, you can use java.util.Random

int myNumber = new Random().nextInt(11) + 10

They refer to the same element, the difference is that when you say document.body you are passing the element directly to jQuery. Alternatively, when you pass the string 'body', the jQuery selector engine has to interpret the string to figure out what element(s) it refers to.

In practice either will get the job done.

If you are interested, there is more information in the documentation for the jQuery function.

You can do this safely (i.e. won't be bugged by files with spaces or \n in their name) with bash:

$ shopt -s nullglob
$ logfiles=(*.log)
$ echo ${#logfiles[@]}

You need to enable nullglob so that you don't get the literal *.log in the $logfiles array if no files match. (See How to "undo" a 'set -x'? for examples of how to safely reset it.)

Use this SQL to get the first 2000 chars of the BLOB.

SELECT utl_raw.cast_to_varchar2(dbms_lob.substr(<YOUR_BLOB_FIELD>,2000,1)) FROM <YOUR_TABLE>;

Note: This is because, Oracle will not be able to handle the conversion of BLOB that is more than length 2000.

Git log but you need to prefix the path with --

Eg:

dan-mac:test dani$ git log file1.txt
fatal: ambiguous argument 'file1.txt': unknown revision or path not in the working tree.

dan-mac:test dani$ git log -- file1.txt

When you really want to write an i-test for a spring data repository you can do it like this:

@RunWith(SpringRunner.class)
@DataJpaTest
@EnableJpaRepositories(basePackageClasses = WebBookingRepository.class)
@EntityScan(basePackageClasses = WebBooking.class)
public class WebBookingRepositoryIntegrationTest {

    @Autowired
    private WebBookingRepository repository;

    @Test
    public void testSaveAndFindAll() {
        WebBooking webBooking = new WebBooking();
        webBooking.setUuid("some uuid");
        webBooking.setItems(Arrays.asList(new WebBookingItem()));
        repository.save(webBooking);

        Iterable<WebBooking> findAll = repository.findAll();

        assertThat(findAll).hasSize(1);
        webBooking.setId(1L);
        assertThat(findAll).containsOnly(webBooking);
    }
}

To follow this example you have to use these dependencies:

<dependency>
    <groupId>com.h2database</groupId>

On a side note, it would have been much easier to just do this.

Solution-1: - If you want to search for a combination of characters or an independent word from a sentence.

String sentence = "In the Name of Allah, the Most Beneficent, the Most Merciful."
if (sentence.matches(".*Beneficent.*")) {return true;}
else{return false;}

Solution-2: - There is another possibility you want to search for an independent word from a sentence then Solution-1 will also return true if you searched a word exists in any other word. For example, If you will search cent from a sentence containing this word ** Beneficent** then Solution-1 will return true. For this remember to add space in your regular expression.

String sentence = "In the Name of Allah, the Most Beneficent, the Most Merciful."
if (sentence.matches(".* cent .*")) {return true;}
else{return false;}

Now in Solution-2 it wll return false because no independent cent word exist.

Additional: You can add or remove space on either side in 2nd solution according to your requirements.

SELECT is_read_committed_snapshot_on FROM sys.databases 
WHERE name= 'YourDatabase'

Return value:

• 1: READ_COMMITTED_SNAPSHOT option is ON. Read operations under the READ COMMITTED isolation level are based on snapshot scans and do not acquire locks.
• 0 (default): READ_COMMITTED_SNAPSHOT option is OFF. Read operations under the READ COMMITTED isolation level use Shared (S) locks.

Try this command:

cat /proc/stat

I built a tool for meta generation. It pre-configures entries for Facebook, Google+ and Twitter, and you can use it free here: http://www.groovymeta.com

To answer the question a bit more, OG tags (Open Graph) tags work similarly to meta tags, and should be placed in the HEAD section of your HTML file. See Facebook's best practises for more information on how to use OG tags effectively.

In my projects, this piece of code always worked as a default serializer which serializes the specified value as if there was no special converter:

serializer.Serialize(writer, value);

If you need to programmatically and asynchronously load a CSS link:

// https://www.filamentgroup.com/lab/load-css-simpler/
function loadCSS(href, position) {
  const link = document.createElement('link');
  link.media = 'print';
  link.rel = 'stylesheet';
  link.href = href;
  link.onload = () => { link.media = 'all'; };
  position.parentNode.insertBefore(link, position);
}

Also, you can create your own outerHeight for HTML elements. I don't know if it works in IE, but it works in Chrome. Perhaps, you can enhance the code below using currentStyle, suggested in the answer above.

Object.defineProperty(Element.prototype, 'outerHeight', {
    'get': function(){
        var height = this.clientHeight;
        var computedStyle = window.getComputedStyle(this); 
        height += parseInt(computedStyle.marginTop, 10);
        height += parseInt(computedStyle.marginBottom, 10);
        height += parseInt(computedStyle.borderTopWidth, 10);
        height += parseInt(computedStyle.borderBottomWidth, 10);
        return height;
    }
});

This piece of code allow you to do something like this:

document.getElementById('foo').outerHeight

According to caniuse.com, getComputedStyle is supported by main browsers (IE, Chrome, Firefox).

Try this:

var thumbnailHold;

    $(".image_thumb").mousedown(function() {
        thumbnailHold = setTimeout(function(){
             checkboxOn(); // Your action Here

         } , 1000);
     return false;
});

$(".image_thumb").mouseup(function() {
    clearTimeout(thumbnailHold);
});

I'd say, it depends on your situation. For example, I work in local government, and we have lots of images like mugshots, etc. We don't have a high number of users, but we need to have good security and auditing around the data. The database is a better solution for us since it makes this easier and we aren't going to run into scaling problems.

On IntelliJ IDEA 2020.2.1

Click on the tab that you want to open as window mode.

Right-click on the tab name and select View mode > Window

If I understand your request correctly, you have to do the following:

public class Section 
{ 
    public String Head
    {
        get
        {
            return SubHead.LastOrDefault();
        }
        set
        {
            SubHead.Add(value);
        }

    public List<string> SubHead { get; private set; }
    public List<string> Content { get; private set; }
} 

You use it like this:

var section = new Section();
section.Head = "Test string";

Now "Test string" is added to the subHeads collection and will be available through the getter:

var last = section.Head; // last will be "Test string"

Hope I understood you correctly.

following lines works for me. I am using mac 10.7.2 .

Without VBA...

If you can use a helper column, you can use the MATCH function to test if a value in one column exists in another column (or in another column on another worksheet). It will return an Error if there is no match

To simply identify duplicates, use a helper column

Assume data in Sheet1, Column A, and another list in Sheet2, Column A. In your helper column, row 1, place the following formula:

=If(IsError(Match(A1, 'Sheet2'!A:A,False)),"","Duplicate")

Drag/copy this forumla down, and it should identify the duplicates.

To highlight cells, use conditional formatting:

With some tinkering, you can use this MATCH function in a Conditional Formatting rule which would highlight duplicate values. I would probably do this instead of using a helper column, although the helper column is a great way to "see" results before you make the conditional formatting rule.

Something like:

=NOT(ISERROR(MATCH(A1, 'Sheet2'!A:A,FALSE)))

For Excel 2007 and prior, you cannot use conditional formatting rules that reference other worksheets. In this case, use the helper column and set your formatting rule in column A like:

=B1="Duplicate"

This screenshot is from the 2010 UI, but the same rule should work in 2007/2003 Excel.

Not to jump into an old issue, but...

#container img {
      max-width:100%;
      height:auto !important;
}

Even though this is not proper as you use the !important override on the height, if you're using a CMS like WordPress that sets the height and width for you, this works well.

It's the comma which is providing that extra white space.

One way is to use the string % method:

print 'Value is "%d"' % (value)

which is like printf in C, allowing you to incorporate and format the items after % by using format specifiers in the string itself. Another example, showing the use of multiple values:

print '%s is %3d.%d' % ('pi', 3, 14159)

For what it's worth, Python 3 greatly improves the situation by allowing you to specify the separator and terminator for a single print call:

>>> print(1,2,3,4,5)
1 2 3 4 5

>>> print(1,2,3,4,5,end='<<\n')
1 2 3 4 5<<

>>> print(1,2,3,4,5,sep=':',end='<<\n')
1:2:3:4:5<<

To run org.apache.http.legacy perfectely in Android 9.0 Pie create an xml file res/xml/network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
    <network-security-config>
      <base-config cleartextTrafficPermitted="true">
       <trust-anchors>
        <certificates src="system" />
       </trust-anchors>
      </base-config>
    </network-security-config>

And add 2 tags tag in your AndroidManifest.xml

android:networkSecurityConfig="@xml/network_security_config" android:name="org.apache.http.legacy"

<?xml version="1.0" encoding="utf-8"?>
 <manifest......>
  <application android:networkSecurityConfig="@xml/network_security_config">

   ......
   ......
 <uses-library
        android:name="org.apache.http.legacy"
        android:required="false"/>
</application>

Also add useLibrary 'org.apache.http.legacy' in your app build gradle

android {
compileSdkVersion 28
defaultConfig {
    applicationId "your application id"
    minSdkVersion 15
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    useLibrary 'org.apache.http.legacy'
}

Yes, you can log queries to a special phpMyAdmin DB table.

See SQL_history.

You could use this to wrap urllib2:

def URLRequest(url, params, method="GET"):
    if method == "POST":
        return urllib2.Request(url, data=urllib.urlencode(params))
    else:
        return urllib2.Request(url + "?" + urllib.urlencode(params))

That will return a Request object that has result data and response codes.

On top of dhobbs answer above (https://stackoverflow.com/a/9728478/624597), here is an extra functionality of storing results to a file (I personally use it to copy and paste to FreeMind to have a nice overview of the structure, therefore I used tabs instead of spaces for indentation):

import os

def list_files(startpath):

    with open("folder_structure.txt", "w") as f_output:
        for root, dirs, files in os.walk(startpath):
            level = root.replace(startpath, '').count(os.sep)
            indent = '\t' * 1 * (level)
            output_string = '{}{}/'.format(indent, os.path.basename(root))
            print(output_string)
            f_output.write(output_string + '\n')
            subindent = '\t' * 1 * (level + 1)
            for f in files:
                output_string = '{}{}'.format(subindent, f)
                print(output_string)
                f_output.write(output_string + '\n')

list_files(".")

I've found the following snippet useful to stick it into a chain of program calls, where URI::Escape might not be installed:

perl -p -e 's/([^A-Za-z0-9])/sprintf("%%%02X", ord($1))/seg'

(source)

how about:

jQuery:

$('.majorpoints').click(function(){
    $(this).find('.hider').toggle();
});

HTML

<div>
  <fieldset class="majorpoints">
    <legend class="majorpointslegend">Expand</legend>
    <div class="hider" style="display:none" >
        <ul>
            <li>cccc</li>
            <li></li>
        </ul>
    </div>
</div>

Fiddle

This way you are binding the click event to the .majorpoints class an you don't have to write it in the HTML each time.

Here's my utility method for getting the local IP address, assuming you are looking for an IPv4 address and the machine only has one real network interface. It could easily be refactored to return an array of IP addresses for multi-interface machines.

function getIPAddress() {
  var interfaces = require('os').networkInterfaces();
  for (var devName in interfaces) {
    var iface = interfaces[devName];

    for (var i = 0; i < iface.length; i++) {
      var alias = iface[i];
      if (alias.family === 'IPv4' && alias.address !== '127.0.0.1' && !alias.internal)
        return alias.address;
    }
  }
  return '0.0.0.0';
}

Here's one application that works for me. In our case...I wanted the Sales team to use SVN for certain docs (Price sheets and such)...but a bit over there head.

I setup an Auto SVN like this: - Created a REPO in my SVN server. - Checked out repo into a DB folder call AutoSVN. - I run EasySVN on my PC, which auto commits and updates the REPO.

With he 'Auto', there are no log comments, but not critical for these particular docs.

The Sales guys use the DB folder...and simply maintain the file name of those docs that need version control such as price sheets.

Try the following Query:

select distinct Users,
 STUFF(
        (
        select ', ' + d.Department FROM @temp d
        where t.Users=d.Users
group by d.Department for xml path('')
        ), 1, 2, '') as Departments
 from @temp t

Implementation:

Declare @temp Table(
ID int,
Users varchar(50),
Department varchar(50)
)
insert into @temp
(ID,Users,Department)
values
(1,'User1','Admin')
insert into @temp
(ID,Users,Department)
values
(2,'User1','Accounts')
insert into @temp
(ID,Users,Department)
values
(3,'User2','Finance')
insert into @temp
(ID,Users,Department)
values
(4,'User3','Sales')
insert into @temp
(ID,Users,Department)
values
(5,'User3','Finance')

 select distinct Users,
 STUFF(
        (
        select ', ' + d.Department FROM @temp d
        where t.Users=d.Users
group by d.Department for xml path('')
        ), 1, 2, '') as Departments

 from @temp t

Result will be:

I am not sure why u want to remove www. But reverse version would be:

# non-www.* -> www.*, if subdomain exist, wont work
RewriteCond %{HTTP_HOST} ^whattimein\.com
RewriteRule ^(.*)$ http://www.whattimein.com/$1 [R=permanent,L]

And advantage of this script is: if u have something like test.whattimein.com or any other (enviroments for developing/testing) it wont redirect U to the original enviroment.

From C# 5.0, you can specify the method as

public async Task<bool> doAsyncOperation()
{
    // do work
    return true;
}

bool result = await doAsyncOperation();

The split method of a string is what you need. In fact the tokenizer class in Java is deprecated in favor of Java's string split method.

Accordingly to W3C checked input's attribute can be absent/ommited or have "checked" as its value. This does not invalidate other values because there's no restriction to the browser implementation to allow values like "true", "on", "yes" and so on. To guarantee that you'll write a cross-browser checkbox/radio use checked="checked", as recommended by W3C.

disabled, readonly and ismap input's attributes go on the same way.

EDITED

empty is not a valid value for checked, disabled, readonly and ismap input's attributes, as warned by @Quentin

git sparse-checkout

Git 2.25.0 includes a new experimental git sparse-checkout command that makes the existing feature easier to use, along with some important performance benefits for large repositories. (The GitHub Blog)

Example with current version:

git clone --filter=blob:none --sparse https://github.com/git/git.git
cd git
git sparse-checkout init --cone
git sparse-checkout add t

Most notably

• --sparse checks out only top-level directory files of git repository into working copy
• git sparse-checkout add t incrementally adds/checks out t subfolder of git

Other elements

• git sparse-checkout init does some preparations to enable partial checkouts
• --filter=blob:none optimizes data fetching by downloading only necessary git objects (take a look at partial clone feature for further infos)
• --cone also speeds up performance by applying more restricted file inclusion patterns

GitHub status

GitHub is still evaluating this feature internally while it’s enabled on a select few repositories [...]. As the feature stabilizes and matures, we’ll keep you updated with its progress. (docs)

There is a setting window.zoom that can enlarge the entire window content including the top menus and side nav tree. Setting this to 1 on a 4k monitor makes the content similar to a 1080p monitor of the same physical size.

My solution is similar to Payam's, except I am using

//older code
//postman.setGlobalVariable("currentDate", new Date().toLocaleDateString());
pm.globals.set("currentDate", new Date().toLocaleDateString());

If you hit the "3 dots" on the folder and click "Edit"

Then set Pre-Request Scripts for the all calls, so the global variable is always available.

This function returns any correct number of months positively or negatively. Found in the comment section here:

function addMonthsToTime($numMonths = 1, $timeStamp = null){
    $timeStamp === null and $timeStamp = time();//Default to the present
    $newMonthNumDays =  date('d',strtotime('last day of '.$numMonths.' months', $timeStamp));//Number of days in the new month
    $currentDayOfMonth = date('d',$timeStamp);

    if($currentDayOfMonth > $newMonthNumDays){
      $newTimeStamp = strtotime('-'.($currentDayOfMonth - $newMonthNumDays).' days '.$numMonths.' months', $timeStamp);
    } else {
    $newTimeStamp = strtotime($numMonths.' months', $timeStamp);
    }

    return $newTimeStamp;
}

The first argument to parse() is the expected format. You have to change that to Date.parse("E MMM dd H:m:s z yyyy", testDate) for it to work. (Note you don't need to create a new Date object, it's a static method)

If you don't know in advance what format, you'll have to find a special parsing library for that. In Ruby there's a library called Chronic, but I'm not aware of a Groovy equivalent. Edit: There is a Java port of the library called jChronic, you might want to check it out.

Alternative solution

In my company, we avoid "jumping over projects" to get to non-common lower level projects. For instance, our presentation/API layer can only reference our domain layer, and the domain layer can only reference the data layer.

However, this is a problem when there are enums that need to be referenced by both the presentation and the domain layers.

Here is the solution that we have implemented (so far). It is a pretty good solution and works well for us. The other answers were hitting all around this.

The basic premise is that enums cannot be inherited - but classes can. So...

// In the lower level project (or DLL)...
public abstract class BaseEnums
{
    public enum ImportanceType
    {
        None = 0,
        Success = 1,
        Warning = 2,
        Information = 3,
        Exclamation = 4
    }

    [Flags]
    public enum StatusType : Int32
    {
        None = 0,
        Pending = 1,
        Approved = 2,
        Canceled = 4,
        Accepted = (8 | Approved),
        Rejected = 16,
        Shipped = (32 | Accepted),
        Reconciled = (64 | Shipped)
    }

    public enum Conveyance
    {
        None = 0,
        Feet = 1,
        Automobile = 2,
        Bicycle = 3,
        Motorcycle = 4,
        TukTuk = 5,
        Horse = 6,
        Yak = 7,
        Segue = 8
    }

Then, to "inherit" the enums in another higher level project...

// Class in another project
public sealed class SubEnums: BaseEnums
{
   private SubEnums()
   {}
}

This has three real advantages...

1. The enum definitions are automatically the same in both projects - by definition.
2. Any changes to the enum definitions are automatically echoed in the second without having to make any modifications to the second class.
3. The enums are based on the same code - so the values can easily be compared (with some caveats).

To reference the enums in the first project, you can use the prefix of the class: BaseEnums.StatusType.Pending or add a "using static BaseEnums;" statement to your usings.

In the second project when dealing with the inherited class however, I could not get the "using static ..." approach to work, so all references to the "inherited enums" would be prefixed with the class, e.g. SubEnums.StatusType.Pending. If anyone comes up with a way to allow the "using static" approach to be used in the second project, let me know.

I am sure that this can be tweaked to make it even better - but this actually works and I have used this approach in working projects.

Please up-vote this if you find it helpful.

If you're using jQuery 2.1.4 or above, try this:

$("#" + this.d);

Or, you can define var before using it. It makes your code simpler.

var d = this.d
$("#" + d);

Some of the reason which I experienced the row selected event not working

1. Style is set up for DataGridCell
2. Using Templated columns
3. Trigger is set up at the DataGridRow

This is what helped me. Setting the Style for DataGridCell

<Style TargetType="{x:Type DataGridCell}">
  <Style.Triggers>
    <Trigger Property="IsSelected" Value="True">
      <Setter Property="Background" Value="Green"/>
      <Setter Property="Foreground" Value="White"/>
    </Trigger>
  </Style.Triggers> 
</Style>

And since I was using a template column with a label inside, I bound the Foreground property to the container Foreground using RelativeSource binding:

<DataGridTemplateColumn>
  <DataGridTemplateColumn.CellTemplate>
    <DataTemplate>
      <Label Content="{Binding CategoryName,
                 Mode=TwoWay,
                 UpdateSourceTrigger=LostFocus}"
             Foreground="{Binding Foreground,
                 RelativeSource={RelativeSource Mode=FindAncestor,
                     AncestorLevel=1, 
                     AncestorType={x:Type DataGridCell}}}"
             Width="150"/>
    </DataTemplate>
  </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

In CSS 2.1, the effect of 'min-height' and 'max-height' on tables, inline tables, table cells, table rows, and row groups is undefined.

So try wrapping the content in a div, and give the div a min-height jsFiddle here

<table cellspacing="0" cellpadding="0" border="0" style="width:300px">
    <tbody>
        <tr>
            <td>
                <div style="min-height: 100px; background-color: #ccc">
                    Hello World !
                </div>
            </td>
            <td>
                <div style="min-height: 100px; background-color: #f00">
                    Good Morning !
                </div>
            </td>
        </tr>
    </tbody>
</table>

I believe that it can be done by simply setting your FormBorderStyle Property to None and the WindowState to Maximized. If you are using Visual Studio both of those can be found in the IDE so there is no need to do so programmatically. Make sure to include some way of closing/exiting the program before doing this cause this will remove that oh so helpful X in the upper right corner.

EDIT:

Try this instead. It is a snippet that I have kept for a long time. I can't even remember who to credit for it, but it works.

Solution

Genetic UITableView Extension For Loadmore.

add this UITableView + Extension in your new file

extension UITableView{

    func indicatorView() -> UIActivityIndicatorView{
        var activityIndicatorView = UIActivityIndicatorView()
        if self.tableFooterView == nil{
            let indicatorFrame = CGRect(x: 0, y: 0, width: self.bounds.width, height: 40)
            activityIndicatorView = UIActivityIndicatorView(frame: indicatorFrame)
            activityIndicatorView.isHidden = false
            activityIndicatorView.autoresizingMask = [.flexibleLeftMargin, .flexibleRightMargin]
            activityIndicatorView.isHidden = true
            self.tableFooterView = activityIndicatorView
            return activityIndicatorView
        }else{
            return activityIndicatorView
        }
    }

    func addLoading(_ indexPath:IndexPath, closure: @escaping (() -> Void)){
        indicatorView().startAnimating()
        if let lastVisibleIndexPath = self.indexPathsForVisibleRows?.last {
            if indexPath == lastVisibleIndexPath && indexPath.row == self.numberOfRows(inSection: 0) - 1 {
                DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
                    closure()
                }
            }
        }
        indicatorView().isHidden = false
    }

    func stopLoading(){
        indicatorView().stopAnimating()
        indicatorView().isHidden = true
    }
}

Now, just add following line of code in UITableViewDelegate Method willDisplay Cell in your ViewController and make sure tableView.delegate = self

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    // need to pass your indexpath then it showing your indicator at bottom 
    tableView.addLoading(indexPath) {
        // add your code here
        // append Your array and reload your tableview
        tableView.stopLoading() // stop your indicator
    }
}

Result

That's it.. Hope this helpful. Thank You

I think there is some confusion about the difference between MVC and Web Api. In short, for MVC you can use a login form and create a session using cookies. For Web Api there is no session. That's why you want to use the token.

You do not need a login form. The Token endpoint is all you need. Like Win described you'll send the credentials to the token endpoint where it is handled.

Here's some client side C# code to get a token:

    //using System;
    //using System.Collections.Generic;
    //using System.Net;
    //using System.Net.Http;
    //string token = GetToken("https://localhost:<port>/", userName, password);

    static string GetToken(string url, string userName, string password) {
        var pairs = new List<KeyValuePair<string, string>>
                    {
                        new KeyValuePair<string, string>( "grant_type", "password" ), 
                        new KeyValuePair<string, string>( "username", userName ), 
                        new KeyValuePair<string, string> ( "Password", password )
                    };
        var content = new FormUrlEncodedContent(pairs);
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
        using (var client = new HttpClient()) {
            var response = client.PostAsync(url + "Token", content).Result;
            return response.Content.ReadAsStringAsync().Result;
        }
    }

In order to use the token add it to the header of the request:

    //using System;
    //using System.Collections.Generic;
    //using System.Net;
    //using System.Net.Http;
    //var result = CallApi("https://localhost:<port>/something", token);

    static string CallApi(string url, string token) {
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
        using (var client = new HttpClient()) {
            if (!string.IsNullOrWhiteSpace(token)) {
                var t = JsonConvert.DeserializeObject<Token>(token);

                client.DefaultRequestHeaders.Clear();
                client.DefaultRequestHeaders.Add("Authorization", "Bearer " + t.access_token);
            }
            var response = client.GetAsync(url).Result;
            return response.Content.ReadAsStringAsync().Result;
        }
    }

Where Token is:

//using Newtonsoft.Json;

class Token
{
    public string access_token { get; set; }
    public string token_type { get; set; }
    public int expires_in { get; set; }
    public string userName { get; set; }
    [JsonProperty(".issued")]
    public string issued { get; set; }
    [JsonProperty(".expires")]
    public string expires { get; set; }
}

Now for the server side:

In Startup.Auth.cs

        var oAuthOptions = new OAuthAuthorizationServerOptions
        {
            TokenEndpointPath = new PathString("/Token"),
            Provider = new ApplicationOAuthProvider("self"),
            AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
            // https
            AllowInsecureHttp = false
        };
        // Enable the application to use bearer tokens to authenticate users
        app.UseOAuthBearerTokens(oAuthOptions);

And in ApplicationOAuthProvider.cs the code that actually grants or denies access:

//using Microsoft.AspNet.Identity.Owin;
//using Microsoft.Owin.Security;
//using Microsoft.Owin.Security.OAuth;
//using System;
//using System.Collections.Generic;
//using System.Security.Claims;
//using System.Threading.Tasks;

public class ApplicationOAuthProvider : OAuthAuthorizationServerProvider
{
    private readonly string _publicClientId;

    public ApplicationOAuthProvider(string publicClientId)
    {
        if (publicClientId == null)
            throw new ArgumentNullException("publicClientId");

        _publicClientId = publicClientId;
    }

    public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();

        var user = await userManager.FindAsync(context.UserName, context.Password);
        if (user == null)
        {
            context.SetError("invalid_grant", "The user name or password is incorrect.");
            return;
        }

        ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager);
        var propertyDictionary = new Dictionary<string, string> { { "userName", user.UserName } };
        var properties = new AuthenticationProperties(propertyDictionary);

        AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
        // Token is validated.
        context.Validated(ticket);
    }

    public override Task TokenEndpoint(OAuthTokenEndpointContext context)
    {
        foreach (KeyValuePair<string, string> property in context.Properties.Dictionary)
        {
            context.AdditionalResponseParameters.Add(property.Key, property.Value);
        }
        return Task.FromResult<object>(null);
    }

    public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
    {
        // Resource owner password credentials does not provide a client ID.
        if (context.ClientId == null)
            context.Validated();

        return Task.FromResult<object>(null);
    }

    public override Task ValidateClientRedirectUri(OAuthValidateClientRedirectUriContext context)
    {
        if (context.ClientId == _publicClientId)
        {
            var expectedRootUri = new Uri(context.Request.Uri, "/");

            if (expectedRootUri.AbsoluteUri == context.RedirectUri)
                context.Validated();
        }
        return Task.FromResult<object>(null);
    }

}

As you can see there is no controller involved in retrieving the token. In fact, you can remove all MVC references if you want a Web Api only. I have simplified the server side code to make it more readable. You can add code to upgrade the security.

Make sure you use SSL only. Implement the RequireHttpsAttribute to force this.

You can use the Authorize / AllowAnonymous attributes to secure your Web Api. Additionally you can add filters (like RequireHttpsAttribute) to make your Web Api more secure. I hope this helps.

Slightly more compact:

df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df = df.sort_index()
print(df)

Note:

• sort has been deprecated, replaced by sort_index for this scenario
• preferable not to use inplace as it is usually harder to read and prevents chaining. See explanation in answer here: Pandas: peculiar performance drop for inplace rename after dropna

I had this same problem and none of the suggested fixes worked for me. So even though this is an old thread, I figure I might as well post my solution in case someone else finds this thread through Google(like I did).

For me, I had to uninstall MinGW/delete the MinGW folder, and re-install. After re-installing it works like a charm.

Like this:

$(".target").each(function(){
    var images = $(this).find(".scrolling img");
    var width = images.width();
    var imgLength = images.length;
    $(this).find(".scrolling").width( width * imgLength * 1.2 );
});

The $(this) refers to the current .target which will be looped through. Within this .target I'm looking for the .scrolling img and get the width. And then keep on going...

Images with different widths

If you want to calculate the width of all images (when they have different widths) you can do it like this:

// Get the total width of a collection.
$.fn.getTotalWidth = function(){
    var width = 0;
    this.each(function(){
        width += $(this).width();
    });
    return width;
}

$(".target").each(function(){
    var images = $(this).find(".scrolling img");
    var width = images.getTotalWidth();
    $(this).find(".scrolling").width( width * 1.2 );
});

Yes, your example would work fine.

As for exposing your classes, you can export a class just like anything else:

class Animal {...}
module.exports = Animal;

Or the shorter:

module.exports = class Animal {

};

Once imported into another module, then you can treat it as if it were defined in that file:

var Animal = require('./Animal');

class Cat extends Animal {
    ...
}

1. You need to make sure that sanitize.js is loaded. For example, load it from https://ajax.googleapis.com/ajax/libs/angularjs/[LAST_VERSION]/angular-sanitize.min.js
2. you need to include ngSanitize module on your app eg: var app = angular.module('myApp', ['ngSanitize']);
3. you just need to bind with ng-bind-html the original html content. No need to do anything else in your controller. The parsing and conversion is automatically done by the ngBindHtml directive. (Read the How does it work section on this: $sce). So, in your case <div ng-bind-html="preview_data.preview.embed.html"></div> would do the work.

SQLite 3

Using getMetaData();

DatabaseMetaData md = conn.getMetaData();
ResultSet rset = md.getColumns(null, null, "your_table_name", null);

System.out.println("your_table_name");
while (rset.next())
{
    System.out.println("\t" + rset.getString(4));
}

EDIT: This works with PostgreSQL as well

First this script test the strings N having chars from 3 to 5.

For multi language (arabic, Ukrainian) you Must use this

var regex = /^([a-zA-Z0-9_-\u0600-\u065f\u066a-\u06EF\u06fa-\u06ff\ufb8a\u067e\u0686\u06af\u0750-\u077f\ufb50-\ufbc1\ufbd3-\ufd3f\ufd50-\ufd8f\ufd92-\ufdc7\ufe70-\ufefc\uFDF0-\uFDFD]+){3,5}$/;  regex.test('?????');

Other wise the below is for English Alphannumeric only

/^([a-zA-Z0-9_-]){3,5}$/

P.S the above dose not accept special characters

one final thing the above dose not take space as test it will fail if there is space if you want space then add after the 0-9\s

\s

And if you want to check lenght of all string add dot .

var regex = /^([a-zA-Z0-9\s@,!=%$#&_-\u0600-\u065f\u066a-\u06EF\u06fa-\u06ff\ufb8a\u067e\u0686\u06af\u0750-\u077f\ufb50-\ufbc1\ufbd3-\ufd3f\ufd50-\ufd8f\ufd92-\ufdc7\ufe70-\ufefc\uFDF0-\uFDFD]).{1,30}$/;

I was used to Home/End getting me to the start and end of lines in Insert mode (from use in Windows and I think Linux), which Mac doesn't support. This is particularly annoying because when I'm using vim on a remote system, I also can't easily do it. After some painful trial and error, I came up with these .vimrc lines which do the same thing, but bound to Ctrl-A for the start of the line and Ctrl-D for the end of the line. (For some reason, Ctrl-E I guess is reserved or at least I couldn't figure a way to bind it.) Enjoy.

:imap <Char-1> <Char-15>:normal 0<Char-13>
:imap <Char-4> <Char-15>:normal $<Char-13>

There's a good chart here for the ASCII control character codes here for others as well:

http://www.physics.udel.edu/~watson/scen103/ascii.html

You can also do Ctrl-V + Ctrl- as well, but that doesn't paste as well to places like this.

If you response is like {'customer':{'first_name':'John','last_name':'Cena'}}

var d = JSON.parse(response);
alert(d.customer.first_name); // contains "John"

Thanks,

There are three ways to save objects from your R session:

Saving all objects in your R session:

The save.image() function will save all objects currently in your R session:

save.image(file="1.RData") 

These objects can then be loaded back into a new R session using the load() function:

load(file="1.RData")

Saving some objects in your R session:

If you want to save some, but not all objects, you can use the save() function:

save(city, country, file="1.RData")

Again, these can be reloaded into another R session using the load() function:

load(file="1.RData") 

Saving a single object

If you want to save a single object you can use the saveRDS() function:

saveRDS(city, file="city.rds")
saveRDS(country, file="country.rds") 

You can load these into your R session using the readRDS() function, but you will need to assign the result into a the desired variable:

city <- readRDS("city.rds")
country <- readRDS("country.rds")

But this also means you can give these objects new variable names if needed (i.e. if those variables already exist in your new R session but contain different objects):

city_list <- readRDS("city.rds")
country_vector <- readRDS("country.rds")

There are scripts on CPAN which attempt to uninstall modules:

• pm-uninstall
• perlrocks

ExtUtils::Packlist shows sample module removing code, modrm.

"\n" is not working everywhere!

For example in email, it adds the exact "\n" into the text instead of a new line if you use it in the custom keyboard like: textDocumentProxy.insertText("\n")

There are another newLine characters available but I can't just simply paste them here (Because they make a new lines).

using this extension:

extension CharacterSet {
    var allCharacters: [Character] {
        var result: [Character] = []
        for plane: UInt8 in 0...16 where self.hasMember(inPlane: plane) {
            for unicode in UInt32(plane) << 16 ..< UInt32(plane + 1) << 16 {
                if let uniChar = UnicodeScalar(unicode), self.contains(uniChar) {
                    result.append(Character(uniChar))
                }
            }
        }
        return result
    }
}

you can access all characters in any CharacterSet. There is a character set called newlines. Use one of them to fulfill your requirements:

let newlines = CharacterSet.newlines.allCharacters
for newLine in newlines {
    print("Hello World \(newLine) This is a new line")
}

Then store the one you tested and worked everywhere and use it anywhere. Note that you can't relay on the index of the character set. It may change.

But most of the times "\n" just works as expected.

If you are user of Anaconda and Spyder then best solution for you is that :

Tools --> Preferences --> Ipython console --> Graphic Section

Then in the Support for graphics (Matplotlib) section:

select two avaliable options

and in the Graphics Backend:

select Automatic

Given your number

x = Decimal('40800000000.00000000000000')

Starting from Python 3,

'{:.2e}'.format(x)

is the recommended way to do it.

e means you want scientific notation, and .2 means you want 2 digits after the dot. So you will get x.xxE±n

The mouse hover effect cannot be implemented in touch device . When I'm appeared with same situation in safari ios I used :active in css to make effect.

ie.

p:active {
  color:red;
}

In my case its working .May be this is also the case that can be used with out using javascript. Just give a try.

cmake --build . --verbose

On Linux and with Makefile generation, this is likely just calling make VERBOSE=1 under the hood, but cmake --build can be more portable for your build system, e.g. working across OSes or if you decide to do e.g. Ninja builds later on:

mkdir build
cd build
cmake ..
cmake --build . --verbose

Its documentation also suggests that it is equivalent to VERBOSE=1:

--verbose, -v

Enable verbose output - if supported - including the build commands to be executed.

This option can be omitted if VERBOSE environment variable or CMAKE_VERBOSE_MAKEFILE cached variable is set.

[EDIT] I made a mistake earlier, because, to get the text, you need to use .getText().toString().

Here is a full working example:

package com.psegina.passwordTest01;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.Toast;

public class Main extends Activity implements OnClickListener {
    LinearLayout l;
    EditText user;
    EditText pwd;
    Button btn;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        l = new LinearLayout(this);
        user = new EditText(this);
        pwd = new EditText(this);
        btn = new Button(this);

        l.addView(user);
        l.addView(pwd);
        l.addView(btn);
        btn.setOnClickListener(this);

        setContentView(l);
    }

    public void onClick(View v){
        String u = user.getText().toString();
        String p = pwd.getText().toString();
        if( u.equals( p ) )
            Toast.makeText(getApplicationContext(), "Matches", Toast.LENGTH_SHORT).show();
        else
            Toast.makeText(getApplicationContext(), user.getText()+" != "+pwd.getText(), Toast.LENGTH_SHORT).show();
    }
}

Original answer (Will not work because of the lack of toString())

Try using .getText() instead of .toString().

if( passw1.getText() == passw2.getText() )
#do something

.toString() returns a String representation of the whole object, meaning it won't return the text you entered in the field (see for yourself by adding a Toast which will show the output of .toString())

I would suggest instead of creating a new table, you just use a view that combines the two tables, this way if any of the data in table 1 or table 2 changes, you don't need to update the third table:

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t1.ID, t2.Number
    FROM    Table1 t1
            INNER JOIN Table2 t2
                ON t1.ID = t2.ID;

If you could have records in one table, and not in the other, then you would need to use a full join:

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, ID = ISNULL(t1.ID, t2.ID), t2.Number
    FROM    Table1 t1
            FULL JOIN Table2 t2
                ON t1.ID = t2.ID;

If you know all records will be in table 1 and only some in table 2, then you should use a LEFT JOIN:

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t1.ID, t2.Number
    FROM    Table1 t1
            LEFT JOIN Table2 t2
                ON t1.ID = t2.ID;

If you know all records will be in table 2 and only some in table 2 then you could use a RIGHT JOIN

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t2.ID, t2.Number
    FROM    Table1 t1
            RIGHT JOIN Table2 t2
                ON t1.ID = t2.ID;

Or just reverse the order of the tables and use a LEFT JOIN (I find this more logical than a right join but it is personal preference):

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t2.ID, t2.Number
    FROM    Table2 t2
            LEFT JOIN Table1 t1
                ON t1.ID = t2.ID;

Procedure to get Python Working in XCode 7

Step 1: Setup your Project with a External Build System

Step 1.1: Edit the Project Scheme

Step 2: Specify Python as the executable for the project (shift-command-g) the path should be /usr/bin/python

Step 3: Specify your custom working directory

Step 4: Specify your command line arguments to be the name of your python file. (in this example "test.py")

Step 5: Thankfully thats it!

(debugging can't be added until OSX supports a python debugger?)

I was having major problems with Axios, Spring Boot and Spring Security with authentication.

Please note the version of Spring Boot and the Spring Security you are using matters.

Spring Boot: 1.5.10 Spring: 4.3.14 Spring Security 4.2.4

To resolve this issue using Annotation Based Java Configuration I created the following class:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

        auth.inMemoryAuthentication()
                .withUser("youruser").password("yourpassword")
                .authorities("ROLE_USER");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.cors().and().
                authorizeRequests()
                .requestMatchers(CorsUtils:: isPreFlightRequest).permitAll()
                .anyRequest()
                .authenticated()
                .and()
                .httpBasic()
                .realmName("Biometrix");

        http.csrf().disable();

    }

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowCredentials(true);
        configuration.setAllowedHeaders(Arrays.asList("Authorization"));
        configuration.setAllowedOrigins(Arrays.asList("*"));
        configuration.setAllowedMethods(Arrays.asList("*"));
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
}

One of the major gotchas with Axios is that when your API requires authentication it sends an Authorization header with the OPTIONS request. If you do not include Authorization in the allowed headers configuration setting our OPTIONS request (aka PreFlight request) will fail and Axios will report an error.

As you can see with a couple of simple and properly placed settings CORS configuration with SpringBoot is pretty easy.

The more easy way its by executing the next command:

ls -ls /usr/bin/python*

Output look like this:

/usr/bin/python           /usr/bin/python2.7        /usr/bin/pythonw
/usr/bin/python-config    /usr/bin/python2.7-config /usr/bin/pythonw2.7

You mean you want 1b and 1b to be side by side?

 <div class="col-lg-6 col-md-6 col-12 child1">
      <div class="col-6 child1a">Child content 1a</div>
      <div class="col-6 child1b">Child content 1b</div>
 </div>

Building on the solution provided I thought it might be helpful to show an example passing your own custom data object (which I've referenced here as 'message' as per question).

Class A (sender):

YourDataObject *message = [[YourDataObject alloc] init];
// set your message properties
NSDictionary *dict = [NSDictionary dictionaryWithObject:message forKey:@"message"];
[[NSNotificationCenter defaultCenter] postNotificationName:@"NotificationMessageEvent" object:nil userInfo:dict];

Class B (receiver):

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[NSNotificationCenter defaultCenter]
     addObserver:self selector:@selector(triggerAction:) name:@"NotificationMessageEvent" object:nil];
}

#pragma mark - Notification
-(void) triggerAction:(NSNotification *) notification
{
    NSDictionary *dict = notification.userInfo;
    YourDataObject *message = [dict valueForKey:@"message"];
    if (message != nil) {
        // do stuff here with your message data
    }
}

References are not objects. They don't have storage of their own, they just reference existing objects. For this reason it doesn't make sense to have arrays of references.

If you want a light-weight object that references another object then you can use a pointer. You will only be able to use a struct with a reference member as objects in arrays if you provide explicit initialization for all the reference members for all struct instances. References cannot be default initalized.

Edit: As jia3ep notes, in the standard section on declarations there is an explicit prohibition on arrays of references.

Regular javascript can be used to trap the backspace key. You can use the event.keyCode method. The keycode is 8, so the code would look something like this:

if (event.keyCode == 8) {
    // Do stuff...
}

If you want to check for both the [delete] (46) as well as the [backspace] (8) keys, use the following:

if (event.keyCode == 8 || event.keyCode == 46) {
    // Do stuff...
}

Tested On Ubuntu 20, sudo chown -R $USER:$USER /var/www

How about this?

>>> import numpy
>>> test1 = numpy.array([1,23,4,6,7,8])
>>> forward = iter(test1)
>>> backward = reversed(test1)
>>> for a in range((len(test1)+1)//2):
...     print forward.next(), backward.next()
... 
1 8
23 7
4 6

The (len(test1)+1)//2 ensures that the middle element of odd length arrays is also returned:

>>> test1 = numpy.array([1,23,4,9,6,7,8]) # additional element '9' in the middle
>>> forward = iter(test1)                                                      
>>> backward = reversed(test1)
>>> for a in range((len(test1)+1)//2):
...     print forward.next(), backward.next()
1 8
23 7
4 6
9 9

Using just len(test1)//2 will drop the middle elemen of odd length arrays.

Go to browser and search for php.ini and then open it, and change these two values:

post_max_size= 1000000000000M

upload_max_filesize= 10000000000000M

If you open the php.ini file using notepad , you can search for these two values by clicking:
cmd + f

I was able to install libc6 2.17 in Debian Wheezy by editing the recommendations in perror's answer:

IMPORTANT
You need to exit out of your display manager by pressing CTRL-ALT-F1. Then you can stop x (slim) with sudo /etc/init.d/slim stop

(replace slim with mdm or lightdm or whatever)

Add the following line to the file /etc/apt/sources.list:

deb http://ftp.debian.org/debian experimental main

Should be changed to:

deb http://ftp.debian.org/debian sid main

Then follow the rest of perror's post:

Update your package database:

apt-get update

Install the eglibc package:

apt-get -t sid install libc6-amd64 libc6-dev libc6-dbg

IMPORTANT
After done updating libc6, restart computer, and you should comment out or remove the sid source you just added (deb http://ftp.debian.org/debian sid main), or else you risk upgrading your whole distro to sid.

Hope this helps. It took me a while to figure out.

You can't really "launch an application" in the true sense. You can as you indicated ask the user to open a document (ie a PDF) and windows will attempt to use the default app for that file type. Many applications have a way to do this.

For example you can save RDP connections as a .rdp file. Putting a link on your site to something like this should allow the user to launch right into an RDP session:

<a href="MyServer1.rdp">Server 1</a>

I don't see what the problem with the timeit module is. This is probably the simplest way to do it.

import timeit
timeit.timeit(a, number=1)

Its also possible to send arguments to the functions. All you need is to wrap your function up using decorators. More explanation here: http://www.pythoncentral.io/time-a-python-function/

The only case where you might be interested in writing your own timing statements is if you want to run a function only once and are also want to obtain its return value.

The advantage of using the timeit module is that it lets you repeat the number of executions. This might be necessary because other processes might interfere with your timing accuracy. So, you should run it multiple times and look at the lowest value.

I was getting this error too, although my issue was that I kept switching between two corporate networks via my Virtual Machine, with different access credentials. I had to run the command prompt:

ipconfig /renew

After this my network issues were resolved and I could connect once again to SQL.

You can write this in a more compact way:

var now = new Date();
now.setTime(now.getTime() + 1 * 3600 * 1000);
document.cookie = "name=value; expires=" + now.toUTCString() + "; path=/";

And for someone like me, who wasted an hour trying to figure out why the cookie with expiration is not set up (but without expiration can be set up) in Chrome, here is in answer:

For some strange reason Chrome team decided to ignore cookies from local pages. So if you do this on localhost, you will not be able to see your cookie in Chrome. So either upload it on the server or use another browser.

I think a much easier way is to use ASIHTTPRequest. Three lines of code can accomplish this:

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadDestinationPath:@"/path/to/my_file.txt"];
[request startSynchronous];

Link to Reference

UPDATE: I should mention that ASIHTTPRequest is no longer maintained. The author has specifically advised people to use other framework instead, like AFNetworking

I was stuck on this for a long time. After a lot of tries I was able to configured it properly.

There can be different reasons of raising the error. I am trying to provide the reason and the solution to overcome from that situation.

1. 6379 Port is not allowed by ufw firewall.

   Solution: type following command sudo ufw allow 6379

2. The issue can be related to permission of redis user. May be redis user doesn't have permission of modifying necessary redis directories. The redis user should have permissions in the following directories:

   • /var/lib/redis
   • /var/log/redis
   • /run/redis
   • /etc/redis

   To give the owner permission to redis user, type the following commands:

   • sudo chown -R redis:redis /var/lib/redis
   • sudo chown -R redis:redis /var/log/redis
   • sudo chown -R redis:redis /run/redis
   • sudo chown -R redis:redis /etc/redis.

   Now restart redis-server by following command:

   sudo systemctl restart redis-server

Hope this will be helpful for somebody.

You could as well take an alternative approach -- you don't have to use $http, you don't need any extra libraries, and it ought to work in any browser.

Just place an invisible form on your page.

<form name="downloadForm" action="/MyApp/MyFiles/Download" method="post" target="_self">
    <input type="hidden" name="value1" value="{{ctrl.value1}}" />
    <input type="hidden" name="value2" value="{{ctrl.value2}}" />
</form>

And place this code in your angular controller.

ctrl.value1 = 'some value 1';  
ctrl.value2 = 'some value 2';  
$timeout(function () {
    $window.document.forms['downloadForm'].submit();
});

This code will post your data to /MyApp/MyFiles/Download and you'll receive a file in your Downloads folder.
It works with Internet Explorer 10.

If a conventional HTML form doesn't let you post your complex object, then you have two options:

1. Stringify your object and put it into one of the form fields as a string.

<input type="hidden" name="myObjJson" value="{{ctrl.myObj | json:0}}" />

2. Consider HTML JSON forms: https://www.w3.org/TR/html-json-forms/

JJB's answer got me on the right track, but the upgrade didn't go very smoothly. My process is detailed below. Hopefully the process becomes easier in the future and JJB's answer can be used or something even more straightforward.

Solution Details

I have followed the steps captured in JJB's answer to update the angular-cli precisely. However, after running npm install angular-cli was broken. Even trying to do ng version would produce an error. So I couldn't do the ng init command. See error below:

$ ng init
core_1.Version is not a constructor
TypeError: core_1.Version is not a constructor
    at Object.<anonymous> (C:\_git\my-project\code\src\main\frontend\node_modules\@angular\compiler-cli\src\version.js:18:19)
    at Module._compile (module.js:556:32)
    at Object.Module._extensions..js (module.js:565:10)
    at Module.load (module.js:473:32)
    ...

To be able to use any angular-cli commands, I had to update my package.json file by hand and bump the @angular dependencies to 2.4.1, then do another npm install.

After this I was able to do ng init. I updated my configuration files, but none of my app/* files. When this was done, I was still getting errors. The first one is detailed below, the second was the same type of error but in a different file.

ERROR in Error encountered resolving symbol values statically. Function calls are not supported. Consider replacing the function or lambda with a reference to an exported function (position 62:9 in the original .ts file), resolving symbol AppModule in C:/_git/my-project/code/src/main/frontend/src/app/app.module.ts

This error is tied to the following factory provider in my AppModule

{ provide: Http, useFactory: 
    (backend: XHRBackend, options: RequestOptions, router: Router, navigationService: NavigationService, errorService: ErrorService) => {
    return new HttpRerouteProvider(backend, options, router, navigationService, errorService);  
  }, deps: [XHRBackend, RequestOptions, Router, NavigationService, ErrorService]
}

To address this error, I had use an exported function and made the following change to the provider.

    { 
      provide: Http, 
      useFactory: httpFactory, 
      deps: [XHRBackend, RequestOptions, Router, NavigationService, ErrorService]
    }

... // elsewhere in AppModule

export function httpFactory(backend: XHRBackend, 
                            options: RequestOptions, 
                            router: Router, 
                            navigationService: NavigationService, 
                            errorService: ErrorService) {
  return new HttpRerouteProvider(backend, options, router, navigationService, errorService);
}

Summary

To summarize what I understand to be the most important details, the following changes were required:

1. Update angular-cli version using the steps detailed in JJB's answer (and on their github page).

2. Updating @angular version by hand, 2.0.0 did not seem to be supported by angular-cli version 1.0.0-beta.24

3. With the assistance of angular-cli and the ng init command, I updated my configuration files. I think the critical changes were to angular-cli.json and package.json. See configuration file changes at the bottom.

4. Make code changes to export functions before I reference them, as captured in the solution details.

Key Configuration Changes

angular-cli.json changes

    "version": "1.0.0-beta.16",
    "name": "frontend"
  },
  "apps": [
    {
      "root": "src",
      "outDir": "dist",
      "assets": "assets",

changed to...

  "project": {
    "version": "1.0.0-beta.24",
    "name": "frontend"
  },

      "outDir": "dist",
      "assets": [
        "assets",
        "favicon.ico"
      ],
...

My package.json looks like this after a manual merge that considers the versions used by ng-init. Note my angular version is not 2.4.1, but the change I was after was component inheritance which was introduced in 2.3, so I was fine with these versions. The original package.json is in the question.

Use Fiddler and grab the view state in the response and paste it into the bottom left text box then decode.

Here's a good technique to display an overlay image that is centered with a semi-transparent background over an image link:

HTML

<div class="image-container">
    <a class="link" href="#" >  
        <img class="image" src="/img/thumbnail.png"/>
        <span class="overlay-image"><img src="/img/overlay.png"></span>
    </a>    
</div>

CSS

div.image-container{
    position: relative;
}
a.link{
    text-decoration: none;  
    position: relative;
    display: block;
}

a.link span.overlay-image{
    visibility: hidden;
    position: absolute;
    left: 0px;
    top: 0px;
    bottom: 0px;
    right: 0px;
    background-color: rgba(0,0,0,0.2); /* black background with 20% alpha */
}

a.link span.overlay-image:before {    /* create a full-height inline block pseudo=element */
    content: ' ';
    display: inline-block;
    vertical-align: middle;  /* vertical alignment of the inline element */
    height: 100%;   
}

a.link:hover span.overlay-image img{
    display: inline-block;  
    vertical-align: middle;     
}

a.link:hover span.overlay-image{
    visibility: visible;
}

Plesk instructions

I combined the top two answers here

In Plesk 12, I had nginx running as a reverse proxy (which I think is the default). So the current top answer doesn't work as nginx is also being run as a proxy.

I went to Subscriptions | [subscription domain] | Websites & Domains (tab) | [Virtual Host domain] | Web Server Settings.

Then at the bottom of that page you can set the Additional nginx directives which I set to be a combination of the top two answers here:

fastcgi_buffers         16  16k;
fastcgi_buffer_size         32k;
proxy_buffer_size          128k;
proxy_buffers            4 256k;
proxy_busy_buffers_size    256k;

If you are dealing with older versions of .NET Framework, then support for TLS 1.2 is available in our SecureBlackbox product in both client and server components. SecureBlackbox contains its own implementation of all algorithms, so it doesn't matter which version of .NET-based framework you use (including .NET CF) - you'll have TLS 1.2 with the latest additions in all cases.

Please note that SecureBlackbox wont magically add TLS 1.2 to framework classes - instead you need to use SecureBlackbox classes and components explicitly.

FileReaderJS can read the files for you. You get the file content inside onLoad(e) event handler as e.target.result.

Having: It applies filter conditions to each group of rows. Where: It applies a filter of individual rows.

If you are running the .java file in Eclipse you need to add the resource path in the build path . after that you will not see this error

This works for me:

curl -I http://websitename.com

Which shows results like this or similar including the PHP version:

HTTP/1.1 200 OK
Date: Thu, 13 Feb 2014 03:40:38 GMT
Server: Apache
X-Powered-By: PHP/5.4.19

Content-Type: text/html; charset=utf-8

Note that if you receive this message:

HTTP/1.1 301 Moved Permanently

You may need to curl the www version of the website instead i.e.:

curl -I http://www.websitename.com

Three ways you can do this - from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol - this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load from the dropdown.

A second way to do it is programmatically - somewhere (constructor maybe) you'd need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);

A third way using the designer (probably the quickest) - when you create a new form, double click on the middle of it on it in design mode. It'll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you're good to go!

almost there, just change outerWidth: 100%; to width: auto; (outerWidth is not a CSS property)

alternatively, apply the following styles to bar:

width: auto;
display: block;

the easiest way to do that in angular or angularjs without external modules or directives is using list and datalist HTML5. You just get a json and use ng-repeat for feeding the options in datalist. The json you can fetch it from ajax.

in this example:

• ctrl.query is the query that you enter when you type.
• ctrl.msg is the message that is showing in the placeholder
• ctrl.dataList is the json fetched

then you can add filters and orderby in the ng-reapet

!! list and datalist id must have the same name !!

 <input type="text" list="autocompleList" ng-model="ctrl.query" placeholder={{ctrl.msg}}>
<datalist id="autocompleList">
        <option ng-repeat="Ids in ctrl.dataList value={{Ids}}  >
</datalist>

UPDATE : is native HTML5 but be carreful with the type browser and version. check it out : https://caniuse.com/#search=datalist.

The way I do this is as follows:

@IBAction func pressButton(sender: AnyObject) {
    var disableMyButton = sender as? UIButton
    disableMyButton.enabled = false
}

The IBAction is connected to your button in the storyboard.

If you have your button setup as an Outlet:

    @IBOutlet weak var myButton: UIButton!

Then you can access the enabled properties by using the . notation on the button name:

    myButton.enabled = false

Complementary answer to Robert's answer http://jsfiddle.net/ak9Sb/ in jQuery

When getting/setting checkbox state, one may encounter these phenomenons:

.trigger("click");

Does check an unchecked checkbox, but do not add the checked attribute. If you use triggers, do not try to get the state with "checked" attribute.

.attr("checked", "");

Does not uncheck the checkbox...

This one works on more than one dropdown in the same page. Furthermore, I added caret on selected item:

    $(".dropdown-menu").on('click', 'li a', function(){
        $(this).parent().parent().siblings(".btn:first-child").html($(this).text()+' <span class="caret"></span>');
        $(this).parent().parent().siblings(".btn:first-child").val($(this).text());
    });

%~dp0 may be a relative path. To convert it to a full path, try something like this:

pushd %~dp0
set script_dir=%CD%
popd

package com.test;

public class Test {

    public static void main(String[] args) {

        String str = "TestCode ";
        if (str.indexOf(" ") > -1) {
            System.out.println("Yes");
        } else {
            System.out.println("Noo");
        }
    }
}

WordUtils.capitalizeFully(str) from apache commons-lang has the exact semantics as required.

paint.setStrokeWidth(3);

paint.setColor(BLACK);

and either one of your drawRect should work.

Simple code in javascript to merge two linked list inplace.

function mergeLists(l1, l2) {
    let head = new ListNode(0); //dummy
    let curr = head;
    while(l1 && l2) {
        if(l2.val >= l1.val) {
            curr.next = l1;
            l1 = l1.next;
        } else {
            curr.next = l2;
            l2=l2.next
        }
        curr = curr.next;
    }
    if(!l1){
        curr.next=l2;
    }
    if(!l2){
        curr.next=l1;
    } 
    return head.next;
}

Open extensions menu (Ctrl+Shift+X), and search .NuGet Package Manager.

This really is beyond the capabilities of shell script. Shell script and the standard Unix tools are okay at parsing line oriented files, but things change when you talk about XML. Even simple tags can present a problem:

<MYTAG>Data</MYTAG>

<MYTAG>
     Data
</MYTAG>

<MYTAG param="value">Data</MYTAG>

<MYTAG><ANOTHER_TAG>Data
</ANOTHER_TAG><MYTAG>

Imagine trying to write a shell script that can read the data enclosed in . The three very, very simply XML examples all show different ways this can be an issue. The first two examples are the exact same syntax in XML. The third simply has an attribute attached to it. The fourth contains the data in another tag. Simple sed, awk, and grep commands cannot catch all possibilities.

You need to use a full blown scripting language like Perl, Python, or Ruby. Each of these have modules that can parse XML data and make the underlying structure easier to access. I've use XML::Simple in Perl. It took me a few tries to understand it, but it did what I needed, and made my programming much easier.

You can get the total number of rows containing a specific name using:

SELECT COUNT(*) FROM tbl_foo WHERE name = 'sarmen'

Given the count, you can now get the nth row using:

SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT (n - 1), 1

Where 1 <= n <= COUNT(*) from the first query.

Example:

getting the 3rd row

SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT 2, 1

Try this:

if cookie and not cookie.isspace():
    # the string is non-empty
else:
    # the string is empty

The above takes in consideration the cases where the string is None or a sequence of white spaces.

You could use a workflow for this.

# ./.github/workflows/rename.yaml
name: Rename Directory

on:
  push:

jobs:
  rename:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - run: git mv old_name new_name
      - uses: EndBug/[email protected]

Then just delete the workflow file, which you can do in the UI

4000 threads at one time is pretty high.

The answer is yes and no. If you are doing a lot of blocking I/O in each thread, then yes, you could show significant speedups doing up to probably 3 or 4 threads per logical core.

If you are not doing a lot of blocking things however, then the extra overhead with threading will just make it slower. So use a profiler and see where the bottlenecks are in each possibly parallel piece. If you are doing heavy computations, then more than 1 thread per CPU won't help. If you are doing a lot of memory transfer, it won't help either. If you are doing a lot of I/O though such as for disk access or internet access, then yes multiple threads will help up to a certain extent, or at the least make the application more responsive.

I answered a similar question here. I looked in a lot of places that always created the same problem. Basically, I did not want to assign a value to the weights, but simply change the weights. The short version of the above answer is:

tf.keras.backend.set_value(tf_var, numpy_weights)

And to complement Rich's recursive answer, a non-recursive method.

Public Sub NonRecursiveMethod()
    Dim fso, oFolder, oSubfolder, oFile, queue As Collection

    Set fso = CreateObject("Scripting.FileSystemObject")
    Set queue = New Collection
    queue.Add fso.GetFolder("your folder path variable") 'obviously replace

    Do While queue.Count > 0
        Set oFolder = queue(1)
        queue.Remove 1 'dequeue
        '...insert any folder processing code here...
        For Each oSubfolder In oFolder.SubFolders
            queue.Add oSubfolder 'enqueue
        Next oSubfolder
        For Each oFile In oFolder.Files
            '...insert any file processing code here...
        Next oFile
    Loop

End Sub

You can use a queue for FIFO behaviour (shown above), or you can use a stack for LIFO behaviour which would process in the same order as a recursive approach (replace Set oFolder = queue(1) with Set oFolder = queue(queue.Count) and replace queue.Remove(1) with queue.Remove(queue.Count), and probably rename the variable...)

The other answers are helpful, but the JSON in your question isn't valid. I have formatted it to make it clearer below, note the missing single quote on line 24.

There are a lot of great articles on how to manipulate objects in Javascript (whether using Node JS or a browser). I suggest here is a good place to start: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Working_with_Objects

gnuplot is an actively maintained program widely used in the scientific community. Normally plots are generated from data files which you can write out in your C# program, but it is also possible to call the gnuplot executable from C# and display the generated image in a C# picture box.

In the HTML source provided, the element #tfl has an inline style "display:block". Inline style will always override stylesheets styles…

Then, you have some options (while as you said you can't modify the html code nor using javascript):

• force display:none with !important rule (not recommended)

• put the div offscreen with theses rules :

  #tfl {
      position: absolute;
      left: -9999px;
  }
  

Use .splice to remove item from array. Using delete, indexes of the array will not be altered but the value of specific index will be undefined

The splice() method changes the content of an array by removing existing elements and/or adding new elements.

Syntax: array.splice(start, deleteCount[, item1[, item2[, ...]]])

var people = ["Bob", "Sally", "Jack"]_x000D_
var toRemove = 'Bob';_x000D_
var index = people.indexOf(toRemove);_x000D_
if (index > -1) { //Make sure item is present in the array, without if condition, -n indexes will be considered from the end of the array._x000D_
  people.splice(index, 1);_x000D_
}_x000D_
console.log(people);

Edit:

As pointed out by justin-grant, As a rule of thumb, Never mutate this.state directly, as calling setState() afterward may replace the mutation you made. Treat this.state as if it were immutable.

The alternative is, create copies of the objects in this.state and manipulate the copies, assigning them back using setState(). Array#map, Array#filter etc. could be used.

this.setState({people: this.state.people.filter(item => item !== e.target.value);});

Right after @mail($email_to, $email_subject, $email_message, $headers);

header('Location: nextpage.php');

Note that you will never see 'Thanks for subscribing to our mailing list'

That should be on the next page, if you echo any text you will get an error because the headers would have been already created, if you want to redirect never return any text, not even a space!

In my case, the dump file I restored had these commands.

CREATE SCHEMA employees;
SET search_path = employees, pg_catalog;

I've commented those and restored again. The issue got resolved

I had this same problem. For me, the reason turned out to be that I had a mismatch in the name of the class and the name of the file. I declared class "GenSig" in a file called "SignatureTester.java".

I changed the name of the class to "SignatureTester", and the "Run as Java Application" option showed up immediately.

Here's a solution to retrieve the html of a webpage using only standard java libraries:

import java.io.*;
import java.net.*;

String urlToRead = "https://google.com";
URL url; // The URL to read
HttpURLConnection conn; // The actual connection to the web page
BufferedReader rd; // Used to read results from the web page
String line; // An individual line of the web page HTML
String result = ""; // A long string containing all the HTML
try {
 url = new URL(urlToRead);
 conn = (HttpURLConnection) url.openConnection();
 conn.setRequestMethod("GET");
 rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
 while ((line = rd.readLine()) != null) {
  result += line;
 }
 rd.close();
} catch (Exception e) {
 e.printStackTrace();
}

System.out.println(result);

SRC

Add the below code

input[type="submit"]:hover {
    border: 1px solid #999;
    color: #000;
}

If you need only for these button then you can add id name

#paginate input[type="submit"]:hover {
    border: 1px solid #999;
    color: #000;
}

DEMO

Just add remove_button_css as class to your button tag. You can verify the code for Link 1

.remove_button_css { 
  outline: none;
  padding: 5px; 
  border: 0px; 
  box-sizing: none; 
  background-color: transparent; 
}

Extra Styles Edit

Add color: #337ab7; and :hover and :focus to match OOTB (bootstrap3)

.remove_button_css:focus,
.remove_button_css:hover {
    color: #23527c;

fig = plt.figure()
ax = fig.add_subplot(111)
plt.xticks([0.4,0.14,0.2,0.2], fontsize = 50) # work on current fig
plt.show()

the x/yticks has the same properties as matplotlib.text

None of the answers address the issue of having children that are NOT React components, such as text strings. A workaround could be something like this:

// Render method of Parent component
render(){
    let props = {
        setAlert : () => {alert("It works")}
    };
    let childrenWithProps = React.Children.map( this.props.children, function(child) {
        if (React.isValidElement(child)){
            return React.cloneElement(child, props);
        }
          return child;
      });
    return <div>{childrenWithProps}</div>

}

Invoke-WebRequest follows the RFC2617 as @briantist noted, however there are some systems (e.g. JFrog Artifactory) that allow anonymous usage if the Authorization header is absent, but will respond with 401 Forbidden if the header contains invalid credentials.

This can be used to trigger the 401 Forbidden response and get -Credentials to work.

$login = Get-Credential -Message "Enter Credentials for Artifactory"

                              #Basic foo:bar
$headers = @{ Authorization = "Basic Zm9vOmJhcg==" }  

Invoke-WebRequest -Credential $login -Headers $headers -Uri "..."

This will send the invalid header the first time, which will be replaced with the valid credentials in the second request since -Credentials overrides the Authorization header.

Tested with Powershell 5.1

As of the current JRE implementation, Function.identity() will always return the same instance while each occurrence of identifier -> identifier will not only create its own instance but even have a distinct implementation class. For more details, see here.

The reason is that the compiler generates a synthetic method holding the trivial body of that lambda expression (in the case of x->x, equivalent to return identifier;) and tell the runtime to create an implementation of the functional interface calling this method. So the runtime sees only different target methods and the current implementation does not analyze the methods to find out whether certain methods are equivalent.

So using Function.identity() instead of x -> x might save some memory but that shouldn’t drive your decision if you really think that x -> x is more readable than Function.identity().

You may also consider that when compiling with debug information enabled, the synthetic method will have a line debug attribute pointing to the source code line(s) holding the lambda expression, therefore you have a chance of finding the source of a particular Function instance while debugging. In contrast, when encountering the instance returned by Function.identity() during debugging an operation, you won’t know who has called that method and passed the instance to the operation.

You can enter the tab character (U+0009 CHARACTER TABULATION, commonly known as TAB or HT) using the character reference 	. It is equivalent to the tab character as such. Thus, from the HTML viewpoint, there is no need to “escape” it using the character reference; but you may do so e.g. if your editing program does not let you enter the character conveniently.

On the other hand, the tab character is in most contexts equivalent to a normal space in HTML. It does not “tabulate”, it’s just a word space.

The tab character has, however, special handling in pre elements and (although this not that well described in specifications) in textarea and xmp element (in the latter, character references cannot be used, only the tab character as such). This is described somewhat misleadingly in HTML specifications, e.g. in HTML 4.01: “[Inside the pre element, ] the horizontal tab character (decimal 9 in [ISO10646] and [ISO88591] ) is usually interpreted by visual user agents as the smallest non-zero number of spaces necessary to line characters up along tab stops that are every 8 characters. We strongly discourage using horizontal tabs in preformatted text since it is common practice, when editing, to set the tab-spacing to other values, leading to misaligned documents.”

The warnings are unnecessary except as regards to the potential mismatch of tabbing in your authoring software and HTML rendering in browsers. The real reason for avoiding horizontal tab is that it a coarse and simplistic tool as compared with tables for presenting tabular material. And in displaying computer source programs, it is better to use just spaces inside pre, since the default tab stops at every 8 characters are quite unsuitable for any normal code indentation style.

In addition, in CSS, you can specify white-space: pre (or, with slightly more limited browser support, white-space: pre-wrap) to make a normal HTML element, like div or p, rendered like pre, so that all whitespace is preserved and horizontal tab has the “tabbing” effect.

In CSS Text Module Level 3 (Last Call working draft, i.e. proceeding towards maturity), there is also the tab-size property, which can be used to set the distance between tab stops, e.g. tab-size: 3. It’s supported by newest versions of most browsers, but not IE (not even IE 11).

I found this version most suitable for all cases. It doesn't remove all whitespaces.

For example "a (test) b" -> "a b"

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim(); "Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();

Use BufferedReader and InputStreamReader classes.

BufferedReader buffer=new BufferedReader(new InputStreamReader(System.in));
String line=buffer.readLine();

Or use java.util.Scanner class methods.

Scanner scan=new Scanner(System.in);

Right click on the project. Go to properties. Click on Run/Debug Settings. Now delete the run config of your main class that you are trying to run. Now, when you hit run again, things would work just fine.

Building off of @gnovice's answer, you can actually create filled plots with shading only in the area between the two curves. Just use fill in conjunction with fliplr.

Example:

x=0:0.01:2*pi;                  %#initialize x array
y1=sin(x);                      %#create first curve
y2=sin(x)+.5;                   %#create second curve
X=[x,fliplr(x)];                %#create continuous x value array for plotting
Y=[y1,fliplr(y2)];              %#create y values for out and then back
fill(X,Y,'b');                  %#plot filled area

By flipping the x array and concatenating it with the original, you're going out, down, back, and then up to close both arrays in a complete, many-many-many-sided polygon.

Change the signature of the CreateFile method to expect a SupportedPermissions value instead of plain Enum.

public string CreateFile(string id, string name, string description, SupportedPermissions supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions
    };

    return file.Id;
}

Then when you call your method you pass the SupportedPermissions value to your method

  var basicFile = CreateFile(myId, myName, myDescription, SupportedPermissions.basic);

Using a getter method is a better design choice for a long-lived class as it allows you to replace the getter method with something more complicated in the future. Although this seems less likely to be needed for a const value, the cost is low and the possible benefits are large.

As an aside, in C++, it's an especially good idea to give both the getter and setter for a member the same name, since in the future you can then actually change the the pair of methods:

class Foo {
public:
    std::string const& name() const;          // Getter
    void name(std::string const& newName);    // Setter
    ...
};

Into a single, public member variable that defines an operator()() for each:

// This class encapsulates a fancier type of name
class fancy_name {
public:
    // Getter
    std::string const& operator()() const {
        return _compute_fancy_name();    // Does some internal work
    }

    // Setter
    void operator()(std::string const& newName) {
        _set_fancy_name(newName);        // Does some internal work
    }
    ...
};

class Foo {
public:
    fancy_name name;
    ...
};

The client code will need to be recompiled of course, but no syntax changes are required! Obviously, this transformation works just as well for const values, in which only a getter is needed.
