From a comment by @pamelus on the accepted answer:

You either have to make all interface properties optional (bad) or specify default value also for all required fields (unnecessary boilerplate) or avoid specifying type on defaultProps.

Actually you can use Typescript's interface inheritance. The resulting code is only a little bit more verbose.

interface OptionalGoogleAdsProps {
    format?: string;
    className?: string;
    style?: any;
    scriptSrc?: string
}

interface GoogleAdsProps extends OptionalGoogleAdsProps {
    client: string;
    slot: string;
}


/**
 * Inspired by https://github.com/wonism/react-google-ads/blob/master/src/google-ads.js
 */
export default class GoogleAds extends React.Component<GoogleAdsProps, void> {
    public static defaultProps: OptionalGoogleAdsProps = {
        format: "auto",
        style: { display: 'block' },
        scriptSrc: "//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"
    };

You can use JavaScript as well, in case the textfield is dithered.

WebDriver driver=new FirefoxDriver();
driver.get("http://localhost/login.do");
driver.manage().window().maximize();
RemoteWebDriver r=(RemoteWebDriver) driver;
String s1="document.getElementById('username').value='admin'";
r.executeScript(s1);

This isn't really recommended, but you can do it all inline like so:

<a href="#" onClick="function test(){ /* Do something */  } test(); return false;"></a>

But I can't think of any situations off hand where this would be better than writing the function somewhere else and invoking it onClick.

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

Using MySQL I usually do it that way:

SELECT count( id ), ...
FROM quote_data
GROUP BY date_format( your_date_column, '%Y%m%d%H' )
order by your_date_column desc;

Or in the same idea, if you need to output the date/hour:

SELECT count( id ) , date_format( your_date_column, '%Y-%m-%d %H' ) as my_date
FROM  your_table 
GROUP BY my_date
order by your_date_column desc;

If you specify an index on your date column, MySQL should be able to use it to speed up things a little.

What if - the Bot does not find any form at all?

3 examples:

1. Insert your form using AJAX

• If you are OK with users having JS disabled and not being able to see/ submit a form, you can notify them and have them enable Javascript first using a noscript statement:

<noscript>
  <p class="error">
    ERROR: The form could not be loaded. Please enable JavaScript in your browser to fully enjoy our services.
  </p>
</noscript>

• Create a form.html and place your form inside a <div id="formContainer"> element.

• Inside the page where you need to call that form use an empty <div id="dynamicForm"></div> and this jQuery: $("#dynamicForm").load("form.html #formContainer");

2. Build your form entirely using JS

// THE FORM
var $form = $("<form/>", {
  appendTo : $("#formContainer"),
  class    : "myForm",
  submit   : AJAXSubmitForm
});

// EMAIL INPUT
$("<input/>",{
  name        : "Email", // Needed for serialization
  placeholder : "Your Email",
  appendTo    : $form,
  on          : {        // Yes, the jQuery's on() Method 
    input : function() {
      console.log( this.value );
    }
  }
});

// MESSAGE TEXTAREA
$("<textarea/>",{
  name        : "Message", // Needed for serialization
  placeholder : "Your message",
  appendTo    : $form
});

// SUBMIT BUTTON
$("<input/>",{
  type        : "submit",
  value       : "Send",
  name        : "submit",
  appendTo    : $form
});

function AJAXSubmitForm(event) {
  event.preventDefault(); // Prevent Default Form Submission
  // do AJAX instead:
  var serializedData = $(this).serialize();
  alert( serializedData );
  $.ajax({
    url: '/mail.php',
    type: "POST",
    data: serializedData,
    success: function (data) {
      // log the data sent back from PHP
      console.log( data );
    }
  });
}

.myForm input,
.myForm textarea{
  font: 14px/1 sans-serif;
  box-sizing: border-box;
  display:block;
  width:100%;
  padding: 8px;
  margin-bottom:12px;
}
.myForm textarea{
  resize: vertical;
  min-height: 120px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="formContainer"></div>

3. Bot-bait input

• Bots like (really like) saucy input elements like:

<input 
  type="text"
  name="email"
  id="email"
  placeholder="Your email"
  autocomplete="nope"
  tabindex="-1"

They wll be happy to enter some value such as
`[email protected]`

• After using the above HTML you can also use CSS to not display the input:

input[name=email]{ /* bait input */
  /* do not use display:none or visibility:hidden
     that will not fool the bot*/
  position:absolute;
  left:-2000px;
}

• Now that your input is not visible to the user expect in PHP that your $_POST["email"] should be empty (without any value)! Otherwise don't submit the form.
• Finally,all you need to do is create another input like <input name="sender" type="text" placeholder="Your email"> after (!) the "bot-bait" input for the actual user Email address.

From angular's documentation,

ng-init SHOULD NOT be used for any initialization. It should be used only for aliasing. https://docs.angularjs.org/api/ng/directive/ngInit

onload should be used if any expression needs to be evaluated after a partial view is loaded (by ng-include). https://docs.angularjs.org/api/ng/directive/ngInclude

The major difference between them is when used with ng-include.

<div ng-include="partialViewUrl" onload="myFunction()"></div>

In this case, myFunction is called everytime the partial view is loaded.

<div ng-include="partialViewUrl" ng-init="myFunction()"></div>

Whereas, in this case, myFunction is called only once when the parent view is loaded.

I am using Matt's excellent answer, but I am seeing a difference between my Windows 7 and Windows 8 systems when running elevated scripts.

Once the script is elevated on Windows 8, the current directory is set to C:\Windows\system32. Fortunately, there is an easy workaround by changing the current directory to the path of the current script:

cd /d %~dp0

Note: Use cd /d to make sure drive letter is also changed.

To test this, you can copy the following to a script. Run normally on either version to see the same result. Run as Admin and see the difference in Windows 8:

@echo off
echo Current path is %cd%
echo Changing directory to the path of the current script
cd %~dp0
echo Current path is %cd%
pause

A novel way to find out the remainder is given below

Statement : Remainder is always constant

ex : 26 divided by 7 gives R : 5 

This can be found out easily by finding the number that completely divides 26 which is closer to the divisor and taking the difference of the both

13 is the next number after 7 that completely divides 26 because after 7 comes 8, 9, 10, 11, 12 where none of them divides 26 completely and give remainder 0.

So 13 is the closest number to 7 which divides to give remainder 0.

Now take the difference (13 ~ 7) = 5 which is the temainder.

Note: for this to work divisor should be reduced to its simplest form ex: if 14 is the divisor, 7 has to be chosen to find the closest number dividing the dividend.

As the OP said that he wants letters and numbers ONLY (no underscore!), one more way to have this in php regex is to use posix expressions:

/^[[:alnum:]]+$/

Note: This will not work in Java, JavaScript, Python, Ruby, .NET

I really think you will benefit from establishing the following function calling coding guidelines:

1. As in all other places, always be const-correct.

   • Note: This means, among other things, that only out-values (see item 3) and values passed by value (see item 4) can lack the const specifier.

2. Only pass a value by pointer if the value 0/NULL is a valid input in the current context.

   • Rationale 1: As a caller, you see that whatever you pass in must be in a usable state.

   • Rationale 2: As called, you know that whatever comes in is in a usable state. Hence, no NULL-check or error handling needs to be done for that value.

   • Rationale 3: Rationales 1 and 2 will be compiler enforced. Always catch errors at compile time if you can.

3. If a function argument is an out-value, then pass it by reference.

   • Rationale: We don't want to break item 2...

4. Choose "pass by value" over "pass by const reference" only if the value is a POD (Plain old Datastructure) or small enough (memory-wise) or in other ways cheap enough (time-wise) to copy.

   • Rationale: Avoid unnecessary copies.
   • Note: small enough and cheap enough are not absolute measurables.

Yes, SERIAL is the equivalent function.

CREATE TABLE foo (
id SERIAL,
bar varchar);

INSERT INTO foo (bar) values ('blah');
INSERT INTO foo (bar) values ('blah');

SELECT * FROM foo;

1,blah
2,blah

SERIAL is just a create table time macro around sequences. You can not alter SERIAL onto an existing column.

With the following streaming code, the Python memory usage is restricted regardless of the size of the downloaded file:

def download_file(url):
    local_filename = url.split('/')[-1]
    # NOTE the stream=True parameter below
    with requests.get(url, stream=True) as r:
        r.raise_for_status()
        with open(local_filename, 'wb') as f:
            for chunk in r.iter_content(chunk_size=8192): 
                # If you have chunk encoded response uncomment if
                # and set chunk_size parameter to None.
                #if chunk: 
                f.write(chunk)
    return local_filename

Note that the number of bytes returned using iter_content is not exactly the chunk_size; it's expected to be a random number that is often far bigger, and is expected to be different in every iteration.

See body-content-workflow and Response.iter_content for further reference.

I assume you don't want to rebind the event, but call the handler.

You can use trigger() to trigger events:

$('#billing_state_id').trigger('change');

If your handler doesn't rely on the event context and you don't want to trigger other handlers for the event, you could also name the function:

function someFunction() {
    //do stuff
}

$(document).ready(function(){
    //Load City by State
    $('#billing_state_id').live('change', someFunction);   
    $('#click_me').live('click', function() {
       //do something
       someFunction();
    });
  });

Also note that live() is deprecated, on() is the new hotness.

CSS

.vr {
   border-right: 1px solid #ccc !important;
}

HTML

<div class="row">
   <div class="col-md-6 vr">
       <p>Column 1</p>
   </div>
   <div class="col-md-6">
       <p>Column 2</p>
   </div>
</div

Now, we can use class vr wherever we need to have a vertical-divider kind of appearance.

Hope it helps!

If you want to SELECT based on the value of another SELECT, then you probably want a "subselect":

http://beginner-sql-tutorial.com/sql-subquery.htm

For example, (from the link above):

1. You want the first and last names from table "student_details" ...

2. But you only want this information for those students in "science" class:

    SELECT id, first_name
    FROM student_details
    WHERE first_name IN (SELECT first_name
    FROM student_details
    WHERE subject= 'Science'); 
   

Frankly, I'm not sure this is what you're looking for or not ... but I hope it helps ... at least a little...

IMHO...

Sorry for tacking on to an old thread, but I think something that was said above may be incorrect/misleading.

From what I can tell .Timeout is NOT the connection time, it is the TOTAL time allowed for the entire life of the HttpWebRequest and response. Proof:

I Set:

.Timeout=5000
.ReadWriteTimeout=32000

The connect and post time for the HttpWebRequest took 26ms

but the subsequent call HttpWebRequest.GetResponse() timed out in 4974ms thus proving that the 5000ms was the time limit for the whole send request/get response set of calls.

I didn't verify if the DNS name resolution was measured as part of the time as this is irrelevant to me since none of this works the way I really need it to work--my intention was to time out quicker when connecting to systems that weren't accepting connections as shown by them failing during the connect phase of the request.

For example: I'm willing to wait 30 seconds on a connection request that has a chance of returning a result, but I only want to burn 10 seconds waiting to send a request to a host that is misbehaving.

Recursively update Windows 7 until it shows no more updates, using Windows Update check option in Windows 7.

Then download and install Visual C++ Redistributable vc_redist.x64.exe from the Windows website.

Then try to run Apache server.

Found an answer myself, this blog helped: http://thingsyoudidntknowaboutjenkins.tumblr.com/post/23596855946/git-plugin-part-3

Basically need to execute:

git checkout master

before modifying any files

then

git commit -am "Updated version number"

after modified files

and then use post build action of Git Publisher with an option of Merge Results which will push changes to github on successful build.

Here is a filter that will take a date string OR javascript Date() object. It uses Moment.js and can apply any Moment.js transform function, such as the popular 'fromNow'

angular.module('myModule').filter('moment', function () {
  return function (input, momentFn /*, param1, param2, ...param n */) {
    var args = Array.prototype.slice.call(arguments, 2),
        momentObj = moment(input);
    return momentObj[momentFn].apply(momentObj, args);
  };
});

So...

{{ anyDateObjectOrString | moment: 'format': 'MMM DD, YYYY' }}

would display Nov 11, 2014

{{ anyDateObjectOrString | moment: 'fromNow' }}

would display 10 minutes ago

If you need to call multiple moment functions, you can chain them. This converts to UTC and then formats...

{{ someDate | moment: 'utc' | moment: 'format': 'MMM DD, YYYY' }}

Objects don't have a .length property.

A simple solution if you know you don't have to worry about hasOwnProperty checks, would be to do this:

Object.keys(data).length;

If you have to support IE 8 or lower, you'll have to use a loop, instead:

var length= 0;
for(var key in data) {
    if(data.hasOwnProperty(key)){
        length++;
    }
}

This article Android Jetpack: What do the recent announcements mean for Android’s Support Library? explains it well

Today, many consider the Support Library an essential part of Android app development, to the point where it’s used by 99 percent of apps in the Google Play store. However, as the Support Library has grown, inconsistencies have crept in surrounding the library’s naming convention.

Initially, the name of each package indicated the minimum API level supported by that package, for example, support-v4. However, version 26.0.0 of the Support Library increased the minimum API to 14, so today many of the package names have nothing to do with the minimum supported API level. When support-v4 and the support-v7 packages both have a minimum API of 14, it’s easy to see why people get confused!

To clear up this confusion, Google is currently refactoring the Support Library into a new Android extension library (AndroidX) package structure. AndroidX will feature simplified package names, as well as Maven groupIds and artifactIds that better reflect each package’s content and its supported API levels.

With the current naming convention, it also isn’t clear which packages are bundled with the Android operating system, and which are packaged with your application’s APK (Android Package Kit). To clear up this confusion, all the unbundled libraries will be moved to AndroidX’s androidx.* namespace, while the android.* package hierarchy will be reserved for packages that ship with the Android operating system.

Possible Permission Issue

I know this post is fairly old, but I ran into a similar issue and my file was spelled correctly.

I originally created the app_offline.htm file in another location and then moved it to the root of my application. Because of my setup I then had a permissions issue.

The website acted as if it was not there. Creating the file within the root directory instead of moving it, fixed my problem. (Or you could just fix the permission in properties->security)

Hope it helps someone.

If error is like Author=models.ForeignKey(User, related_names='blog_posts') TypeError:init() missing 1 required positional argument:'on_delete'

Then the solution will be like, you have to add one argument Author=models.ForeignKey(User, related_names='blog_posts', on_delete=models.DO_NOTHING)

You can try using the a backslash followed by a "u" and then the unicode value for the character, for example the unicode value of the double quote is

" -> U+0022

Therefore if you were setting it as part of text in XML in android it would look something like this,

<TextView
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:text=" \u0022 Showing double quotes \u0022 "/>

This would produce a text in the TextView roughly something like this

" Showing double quotes "

You can find unicode of most symbols and characters here www.unicode-table.com/en

I'd recommend looking at consistent gets/logical reads as a better proxy for 'work' than run time. The run time can be skewed by what else is happening on the database server, how much stuff is in the cache etc.

But if you REALLY want SQL executing time, the V$SQL view has both CPU_TIME and ELAPSED_TIME.

Sure it's possible... use Export Wizard in source option use SQL SERVER NATIVE CLIENT 11, later your source server ex.192.168.100.65\SQLEXPRESS next step select your new destination server ex.192.168.100.65\SQL2014

Just be sure to be using correct instance and connect each other

Just pay attention in Stored procs must be recompiled

ORDER BY article_rating ASC , article_time DESC

DESC at the end will sort by both columns descending. You have to specify ASC if you want it otherwise

The equivalent C code looks like this:

#include <stdio.h>
#include <string.h>

// This code outputs: h is in "This is my test string"
int main(int argc, char* argv[])
{
   const char *invalid_characters = "hz";
   char *mystring = "This is my test string";
   char *c = mystring;
   while (*c)
   {
       if (strchr(invalid_characters, *c))
       {
          printf("%c is in \"%s\"\n", *c, mystring);
       }

       c++;
   }

   return 0;
}

Note that invalid_characters is a C string, ie. a null-terminated char array.

For small sized list we can create LinkedList and then can make use of descending iterator as:

List<String> stringList = new ArrayList<>(Arrays.asList("One", "Two", "Three"));
stringList.stream().collect(Collectors.toCollection(LinkedList::new))
         .descendingIterator().
         forEachRemaining(System.out::println); // Three, Two, One
System.out.println(stringList); // One, Two, Three

To effectively use the typing module (new in Python 3.5) include all (*).

from typing import *

And you will be ready to use:

List, Tuple, Set, Map - for list, tuple, set and map respectively.
Iterable - useful for generators.
Any - when it could be anything.
Union - when it could be anything within a specified set of types, as opposed to Any.
Optional - when it might be None. Shorthand for Union[T, None].
TypeVar - used with generics.
Callable - used primarily for functions, but could be used for other callables.

However, still you can use type names like int, list, dict,...

I had the same issue. I came up with a simple solution. Use fragment .replace instead of fragment .add. Replacing fragment doing the same thing as adding fragment and then removing it manually.

getFragmentManager().beginTransaction().replace(fragment).commit();

instead of

getFragmentManager().beginTransaction().add(fragment).commit();

This may be helpful if you have more than one python versions installed and dont know how to tell your ide's to use a specific version.

1. Install anaconda. Latest version can be found here
2. Open the navigator by typing anaconda-navigator in terminal
3. Open environments. Click on create and then choose your python version in that.
4. Now new environment will be created for your python version and you can install the IDE's(which are listed there) just by clicking install in that.
5. Launch the IDE in your environment so that that IDE will use the specified version for that environment.

Hope it helps!!

From the C99 standard (C++ should be the same, barring strange overloading)

6.5.2.4 Postfix increment and decrement operators

Constraints

1 The operand of the postfix increment or decrement operator shall have qualified or unqualified real or pointer type and shall be a modifiable lvalue.

Semantics

2 The result of the postfix ++ operator is the value of the operand. After the result is obtained, the value of the operand is incremented. (That is, the value 1 of the appropriate type is added to it.) See the discussions of additive operators and compound assignment for information on constraints, types, and conversions and the effects of operations on pointers. The side effect of updating the stored value of the operand shall occur between the previous and the next sequence point.

3 The postfix -- operator is analogous to the postfix ++ operator, except that the value of the operand is decremented (that is, the value 1 of the appropriate type is subtracted from it).

6.5.3.1 Prefix increment and decrement operators

Constraints

1 The operand of the prefix increment or decrement operator shall have qualified or unqualified real or pointer type and shall be a modifiable lvalue.

Semantics

2 The value of the operand of the prefix ++ operator is incremented. The result is the new value of the operand after incrementation. The expression ++E is equivalent to (E+=1). See the discussions of additive operators and compound assignment for information on constraints, types, side effects, and conversions and the effects of operations on pointers.

3 The prefix -- operator is analogous to the prefix ++ operator, except that the value of the operand is decremented.

If you use the WEB API with Claims, you can use this:

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class AutorizeCompanyAttribute:  AuthorizationFilterAttribute
{
    public string Company { get; set; }

    public override void OnAuthorization(HttpActionContext actionContext)
    {
        var claims = ((ClaimsIdentity)Thread.CurrentPrincipal.Identity);
        var claim = claims.Claims.Where(x => x.Type == "Company").FirstOrDefault();

        string privilegeLevels = string.Join("", claim.Value);        

        if (privilegeLevels.Contains(this.Company)==false)
        {
            actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized, "Usuario de Empresa No Autorizado");
        }
    }
}
[HttpGet]
[AutorizeCompany(Company = "MyCompany")]
[Authorize(Roles ="SuperAdmin")]
public IEnumerable MyAction()
{....
}

If your changes have already been pushed to a public, shared remote, and you want to revert all commits between HEAD and <sha-id>, then you can pass a commit range to git revert,

git revert 56e05f..HEAD

and it will revert all commits between 56e05f and HEAD (excluding the start point of the range, 56e05f).

Another option is to enclose the unwanted lines in an IF block that can never be true

if 1==0 (
...
)

Of course nothing within the if block will be executed, but it will be parsed. So you can't have any invalid syntax within. Also, the comment cannot contain ) unless it is escaped or quoted. For those reasons the accepted GOTO solution is more reliable. (The GOTO solution may also be faster)

Update 2017-09-19

Here is a cosmetic enhancement to pdub's GOTO solution. I define a simple environment variable "macro" that makes the GOTO comment syntax a bit better self documenting. Although it is generally recommended that :labels are unique within a batch script, it really is OK to embed multiple comments like this within the same batch script.

@echo off
setlocal

set "beginComment=goto :endComment"

%beginComment%
Multi-line comment 1
goes here
:endComment

echo This code executes

%beginComment%
Multi-line comment 2
goes here
:endComment

echo Done

Or you could use one of these variants of npocmaka's solution. The use of REM instead of BREAK makes the intent a bit clearer.

rem.||(
   remarks
   go here
)

rem^ ||(
   The space after the caret
   is critical
)

1- create a file in the project root call it settings.js

2- inside this file add this code

module.exports = {
    POST_MAX_SIZE : 40 , //MB
    UPLOAD_MAX_FILE_SIZE: 40, //MB
    PROJECT_DIR : __dirname
};

3- inside node_modules create a new module name it "settings" and inside the module index.js write this code:

module.exports = require("../../settings");

4- and any time you want your project directory just use

var settings = require("settings");
settings.PROJECT_DIR; 

in this way you will have all project directories relative to this file ;)

I'm not sure at what level you're asking this question. It sounds as if you've found the formulas online, and are just trying to understand what it does. On that reading of your question I offer:

• Imagine a ray from the viewer (at point V) directly towards the center of the projection plane (call it C).
• Imagine a second ray from the viewer to a point in the image (P) which also intersects the projection plane at some point (Q)
• The viewer and the two points of intersection on the view plane form a triangle (VCQ); the sides are the two rays and the line between the points in the plane.
• The formulas are using this triangle to find the coordinates of Q, which is where the projected pixel will go

Response.write() don't give formatted output. The latter one allows you to write formatted output.

Response.write - it writes the text stream Response.output.write - it writes the HTTP Output Stream.

As discussed in the jQuery UI forums, you should not use accordions for this.

If you want something that looks and acts like an accordion, that is fine. Use their classes to style them, and implement whatever functionality you need. Then adding a button to open or close them all is pretty straightforward. Example

HTML

By using the jquery-ui classes, we keep our accordions looking just like the "real" accordions.

<div id="accordion" class="ui-accordion ui-widget ui-helper-reset">
    <h3 class="accordion-header ui-accordion-header ui-helper-reset ui-state-default ui-accordion-icons ui-corner-all">
        <span class="ui-accordion-header-icon ui-icon ui-icon-triangle-1-e"></span>
        Section 1
    </h3>
    <div class="ui-accordion-content ui-helper-reset ui-widget-content ui-corner-bottom">
        Content 1
    </div>
</div>?

Roll your own accordions

Mostly we just want accordion headers to toggle the state of the following sibling, which is it's content area. We have also added two custom events "show" and "hide" which we will hook into later.

var headers = $('#accordion .accordion-header');
var contentAreas = $('#accordion .ui-accordion-content ').hide();
var expandLink = $('.accordion-expand-all');

headers.click(function() {
    var panel = $(this).next();
    var isOpen = panel.is(':visible');

    // open or close as necessary
    panel[isOpen? 'slideUp': 'slideDown']()
        // trigger the correct custom event
        .trigger(isOpen? 'hide': 'show');

    // stop the link from causing a pagescroll
    return false;
});

Expand/Collapse All

We use a boolean isAllOpen flag to mark when the button has been changed, this could just as easily have been a class, or a state variable on a larger plugin framework.

expandLink.click(function(){
    var isAllOpen = $(this).data('isAllOpen');

    contentAreas[isAllOpen? 'hide': 'show']()
        .trigger(isAllOpen? 'hide': 'show');
});

Swap the button when "all open"

Thanks to our custom "show" and "hide" events, we have something to listen for when panels are changing. The only special case is "are they all open", if yes the button should be a "Collapse all", if not it should be "Expand all".

contentAreas.on({
    // whenever we open a panel, check to see if they're all open
    // if all open, swap the button to collapser
    show: function(){
        var isAllOpen = !contentAreas.is(':hidden');   
        if(isAllOpen){
            expandLink.text('Collapse All')
                .data('isAllOpen', true);
        }
    },
    // whenever we close a panel, check to see if they're all open
    // if not all open, swap the button to expander
    hide: function(){
        var isAllOpen = !contentAreas.is(':hidden');
        if(!isAllOpen){
            expandLink.text('Expand all')
            .data('isAllOpen', false);
        } 
    }
});?

Edit for comment: Maintaining "1 panel open only" unless you hit the "Expand all" button is actually much easier. Example

Watch out for the trap I got into: When checking if certain value is not present in an array, you shouldn't do:

SELECT value_variable != ANY('{1,2,3}'::int[])

but use

SELECT value_variable != ALL('{1,2,3}'::int[])

instead.

For MySQL 8.0 just:

SET PASSWORD FOR 'root'@'localhost' = '';

I presume that this question is a continuation of this one.

What are you trying to do? Do you really want to dynamically change the text in your TextView objects when the user clicks a button? You can certainly do that, if you have a reason, but, if the text is static, it is usually set in the main.xml file, like this:

<TextView  
android:id="@+id/rate"
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:text="@string/rate"
/>

The string "@string/rate" refers to an entry in your strings.xml file that looks like this:

<string name="rate">Rate</string>

If you really want to change this text later, you can do so by using Nikolay's example - you'd get a reference to the TextView by utilizing the id defined for it within main.xml, like this:

final TextView textViewToChange = (TextView) findViewById(R.id.rate);
textViewToChange.setText(
    "The new text that I'd like to display now that the user has pushed a button.");

While the w32tm /resync in theory does the job, it only does so under certain conditions. When "down to the millisecond" matters, however, I found that Windows wouldn't actually make the adjustment; as if "oh, I'm off by 2.5 seconds, close enough bro, nothing to see or do here".

In order to truly force the resync (Windows 7):

1. Control Panel -> Date and Time
2. "Change date and time..." (requires Admin privileges)
3. Add or Subtract a few minutes (I used -5 minutes)
4. Run "cmd.exe" as administrator
5. w32tm /resync
6. Visually check that the seconds in the "Date and Time" control panel are ticking at the same time as your authoritative clock(s). (I used watch -n 0.1 date on a Linux machine on the network that I had SSH'd over into)

--- Rapid Method ---

1. Run "cmd.exe" as administrator
2. net start w32time (Time Service must be running)
3. time 8 (where 8 may be replaced by any 'hour' value, presumably 0-23)
4. w32tm /resync
5. Jump to 3, as needed.

In JavaScript this always refers to the “owner” of the function we're executing, or rather, to the object that a function is a method of. When we define our faithful function doSomething() in a page, its owner is the page, or rather, the window object (or global object) of JavaScript.

How does the "this" keyword work?

Not an answer to the full question but I think it's worth to mention that in Node.js 10 a new util function called isPromise was added which checks if an object is a native Promise or not:

const utilTypes = require('util').types
const b_Promise = require('bluebird')

utilTypes.isPromise(Promise.resolve(5)) // true
utilTypes.isPromise(b_Promise.resolve(5)) // false

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

Say there is EditText et1 in ur MainActivity and u wanna pass this to SecondActivity

String s=et1.getText().toString();
Bundle basket= new Bundle();
basket.putString("abc", s);
Intent a=new Intent(MainActivity.this,SecondActivity.class);
a.putExtras(basket);
startActivity(a);

now in Second Activity, say u wanna put the string passed from EditText et1 to TextView txt1 of SecondActivity

Bundle gt=getIntent().getExtras();
str=gt.getString("abc");
txt1.setText(str);

For those who want a right triangle arrow, here you go:

STEP 1: Create a drawable XML file, copy and paste the following XML content into your drawable XML. (Please be informed that you can use any name for your drawable XML file. For my case, I name it "v_right_arrow")

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item >
        <rotate
            android:fromDegrees="45"
            android:toDegrees="-45"
            android:pivotX="15%"
            android:pivotY="-36%" >
            <shape
                android:shape="rectangle"  >
                <stroke android:color="@android:color/transparent" android:width="1dp"/>
                <solid
                    android:color="#000000"  />
            </shape>
        </rotate>
    </item>
</layer-list>

STEP 2: In your layout's XML, create a View and bind its background to the drawable XML that you have just created in STEP 1. For my case, I bind v_right_arrow to my View's background property.

<View
    android:layout_width="200dp"
    android:layout_height="200dp"
    android:background="@drawable/v_right_arrow">
</View>

Sample output:

Hope this helps, good luck!

if you need to add a date-time to your backup file name (Centos7) use the following:

/usr/bin/mysqldump -u USER -pPASSWD DBNAME | gzip > ~/backups/db.$(date +%F.%H%M%S).sql.gz

this will create the file: db.2017-11-17.231537.sql.gz

 using (FileStream fs = new FileStream(fileName,FileMode.Append, FileAccess.Write))
 using (StreamWriter sw = new StreamWriter(fs))
 {
    sw.WriteLine(something);
 }

Locking on the this pointer can be bad if you are locking over a shared resource. A shared resource can be a static variable or a file on your computer - i.e. something that is shared between all users of the class. The reason is that the this pointer will contain a different reference to a location in memory each time your class is instantiated. So, locking over this in once instance of a class is different than locking over this in another instance of a class.

Check out this code to see what I mean. Add the following code to your main program in a Console application:

    static void Main(string[] args)
    {
         TestThreading();
         Console.ReadLine();
    }

    public static void TestThreading()
    {
        Random rand = new Random();
        Thread[] threads = new Thread[10];
        TestLock.balance = 100000;
        for (int i = 0; i < 10; i++)
        {
            TestLock tl = new TestLock();
            Thread t = new Thread(new ThreadStart(tl.WithdrawAmount));
            threads[i] = t;
        }
        for (int i = 0; i < 10; i++)
        {
            threads[i].Start();
        }
        Console.Read();
    }

Create a new class like the below.

 class TestLock
{
    public static int balance { get; set; }
    public static readonly Object myLock = new Object();

    public void Withdraw(int amount)
    {
      // Try both locks to see what I mean
      //             lock (this)
       lock (myLock)
        {
            Random rand = new Random();
            if (balance >= amount)
            {
                Console.WriteLine("Balance before Withdrawal :  " + balance);
                Console.WriteLine("Withdraw        : -" + amount);
                balance = balance - amount;
                Console.WriteLine("Balance after Withdrawal  :  " + balance);
            }
            else
            {
                Console.WriteLine("Can't process your transaction, current balance is :  " + balance + " and you tried to withdraw " + amount);
            }
        }

    }
    public void WithdrawAmount()
    {
        Random rand = new Random();
        Withdraw(rand.Next(1, 100) * 100);
    }
}

Here is a run of the program locking on this.

@Mikael Svenson's answer is correct. I just wanted to add a small addition to it:

The Messagebox icon can also be included has an additional property like below:

DialogResult dialogResult = MessageBox.Show("Sure", "Please Confirm Your Action", MessageBoxButtons.YesNo, MessageBoxIcon.Question);

/*reading string which contains spaces*/
#include<stdio.h>
int main()
{
   char *c,*p;
   scanf("%[^\n]s",c);
   p=c;                /*since after reading then pointer points to another 
                       location iam using a second pointer to store the base 
                       address*/ 
   printf("%s",p);
   return 0;
 }

You can't return ajax return value. You stored global variable store your return values after return.
Or Change ur code like this one.

AjaxGet = function (url) {
    var result = $.ajax({
        type: "POST",
        url: url,
       param: '{}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
       async: false,
        success: function (data) {
            // nothing needed here
      }
    }) .responseText ;
    return  result;
}

It will group by the column position you put after the group by clause.

for example if you run 'SELECT SALESMAN_NAME, SUM(SALES) FROM SALES GROUP BY 1' it will group by SALESMAN_NAME.

One risk on doing that is if you run 'Select *' and for some reason you recreate the table with columns on a different order, it will give you a different result than you would expect.

Great technical answers in the post! I have nothing technically to add to that.

One of the main reasons why new features appear in languages and software in general is marketing or company politics! :-) This must not be under estimated!

I think this applies to certain extend to delegates and events too! i find them useful and add value to the C# language, but on the other hand the Java language decided not to use them! they decided that whatever you are solving with delegates you can already solve with existing features of the language i.e. interfaces e.g.

Now around 2001 Microsoft released the .NET framework and the C# language as a competitor solution to Java, so it was good to have NEW FEATURES that Java doesn't have.

You only get that message if you try to use Designer or diagrams. If you use t-SQL it works fine:

Select * 

into newdb.dbo.newtable
from olddb.dbo.yourtable

where olddb.dbo.yourtable has been created in 2008 exactly as you want the table to be in 2012

You need to use the scrollTop property.

document.getElementById('box').scrollTop

You can just run "Java VisualVM" which is located at jdk/bin/jvisualvm.exe

This will open a GUI, use the "File" menu -> "Load..." then choose your *.hprof file

That's it, you're done!

Typing 'my IP' in google search I got my public IP address and pasted it in IP address (the third option). It works for me.

I was just working on this, I may be a bit late, but I did a workaround. Here are steps: - Get current time from whatever timezone the app is fired.- - Get time zone offset of that zone from gmt 0. then add your timezone value in miliseconds. You will get the date in your time zone. I added some extra code to remove anything after the actual time.

getCurrentDate() {
    var date = new Date();
    var newDate = new Date(8 * 60 * 60000 + date.valueOf() + 
                           (date.getTimezoneOffset() * 60000));
    var ampm = newDate.getHours() < 12 ? ' AM' : ' PM';
    var strDate = newDate + '';
    return (strDate).substring(0, strDate.indexOf(' GMT')) + ampm
}

I did not manage to make the most popular answers work.

• The ee method complained when my replacement string contained several consecutive backreferences.
• Kent Fredric's answer only replaced the first match, and I need my search and replace to be global. I did not figure out a way to make it replace all matches that didn't cause other issues. For example, I tried running the method recursively until it no longer caused the string to change, but that causes an infinite loop if the replacement string contains the search string, whereas a regular global replacement does not do that.

I attempted to come up with a solution of my own using plain old eval:

eval '$var =~ s/' . $find . '/' . $replace . '/gsu;';

Of course, this allows for code injection. But as far as I know, the only way to escape the regex query and inject code is to insert two forward slashes in $find or one in $replace, followed by a semi-colon, after which you can add add code. For example, if I set the variables this way:

my $find = 'foo';
my $replace = 'bar/; print "You\'ve just been hacked!\n"; #';

The evaluated code is this:

$var =~ s/foo/bar/; print "You've just been hacked!\n"; #/gsu;';

So what I do is make sure the strings don't contain any unescaped forward slashes.

First, I copy the strings into dummy strings.

my $findTest = $find;
my $replaceTest = $replace;

Then, I remove all escaped backslashes (backslash pairs) from the dummy strings. This allows me to find forward slashes that are not escaped, without falling into the trap of considering a forward slash escaped if it's preceded by an escaped backslash. For example: \/ contains an escaped forward slash, but \\/ contains a literal forward slash, because the backslash is escaped.

$findTest =~ s/\\\\//gmu;
$replaceTest =~ s/\\\\//gmu;

Now if any forward slash that is not preceded by a backslash remains in the strings, I throw a fatal error, as that would allow the user to insert arbitrary code.

if ($findTest =~ /(?<!\\)\// || $replaceTest =~ /(?<!\\)\//)
{
  print "String must not contain unescaped slashes.\n";
  exit 1;
}

Then I eval.

I'm not an expert at preventing code injection, but I'm the only one using my script, so I'm content using this solution without fully knowing if it's vulnerable. But as far as I know, it may be, so if anyone knows if there is or isn't any way to inject code into this, please provide your insight in a comment.

CHARINDEX() searches for a substring within a larger string, and returns the position of the match, or 0 if no match is found

if CHARINDEX('ME',@mainString) > 0
begin
    --do something
end

Edit or from daniels answer, if you're wanting to find a word (and not subcomponents of words), your CHARINDEX call would look like:

CHARINDEX(' ME ',' ' + REPLACE(REPLACE(@mainString,',',' '),'.',' ') + ' ')

(Add more recursive REPLACE() calls for any other punctuation that may occur)

Ajax.ActionLink only sends an ajax request to the server. What happens ahead really depends upon type of data returned and what your client side script does with it. You may send a partial view for ajax call or json, xml etc. Ajax.ActionLink however have different callbacks and parameters that allow you to write js code on different events. You can do something before request is sent or onComplete. similarly you have an onSuccess callback. This is where you put your JS code for manipulating result returned by server. You may simply put it back in UpdateTargetID or you can do fancy stuff with this result using jQuery or some other JS library.

I'm on Gson 2.8.6 and discovered this bug today.

My approach allows all our existing clients (mobile/web/etc) to continue functioning as they were, but adds some handling for those using 24h formats and allows millis too, for good measure.

Gson rawGson = new Gson();
SimpleDateFormat fmt = new SimpleDateFormat("MMM d, yyyy HH:mm:ss")
private class DateDeserializer implements JsonDeserializer<Date> {
    @Override
    public Date deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context)
            throws JsonParseException {
        try {
            return new rawGson.fromJson(json, Date.class);
        } catch (JsonSyntaxException e) {}
        String timeString = json.getAsString();
        log.warning("Standard date deserialization didn't work:" + timeString);
        try {
            return fmt.parse(timeString);
        } catch (ParseException e) {}
        log.warning("Parsing as json 24 didn't work:" + timeString);
        return new Date(json.getAsLong());
    }
}

Gson gson = new GsonBuilder()
    .registerTypeAdapter(Date.class, new DateDeserializer())
    .create();

I kept serialization the same as all clients understand the standard json date format.

Ordinarily, I don't think it's good practice to use try/catch blocks, but this should be a fairly rare case.

Get device token in Swift 3

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

    let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})

    print("Device token: \(deviceTokenString)")

}

Suppose you want to store the result of an echo command

echo hello   
x=$(echo hello)  
echo "$x",world!  

output:

hello  
hello,world!

Similar SO question here.

I liked the using a StringBuilder extension method.

RemoveLast Method

Basically, with prepared statements the data coming in from a potential hacker is treated as data - and there's no way it can be intermixed with your application SQL and/or be interpreted as SQL (which can happen when data passed in is placed directly into your application SQL).

This is because prepared statements "prepare" the SQL query first to find an efficient query plan, and send the actual values that presumably come in from a form later - at that time the query is actually executed.

More great info here:

Prepared statements and SQL Injection

Neither code is always better. They do different things, so they are good at different things.

InvariantCultureIgnoreCase uses comparison rules based on english, but without any regional variations. This is good for a neutral comparison that still takes into account some linguistic aspects.

OrdinalIgnoreCase compares the character codes without cultural aspects. This is good for exact comparisons, like login names, but not for sorting strings with unusual characters like é or ö. This is also faster because there are no extra rules to apply before comparing.

You can overload the main() method, but only public static void main(String[] args) will be used when your class is launched by the JVM. For example:

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

    public static void main(String arg1) {
        System.out.println("main(String arg1)");
    }

    public static void main(String arg1, String arg2) {
        System.out.println("main(String arg1, String arg2)");
    }
}

That will always print main(String[] args) when you run java Test ... from the command line, even if you specify one or two command-line arguments.

You can call the main() method yourself from code, of course - at which point the normal overloading rules will be applied.

EDIT: Note that you can use a varargs signature, as that's equivalent from a JVM standpoint:

public static void main(String... args)

The place where each can cause you problems is that it's a true, non-scoped iterator. By way of example:

while ( my ($key,$val) = each %a_hash ) {
    print "$key => $val\n";
    last if $val; #exits loop when $val is true
}

# but "each" hasn't reset!!
while ( my ($key,$val) = each %a_hash ) {
    # continues where the last loop left off
    print "$key => $val\n";
}

If you need to be sure that each gets all the keys and values, you need to make sure you use keys or values first (as that resets the iterator). See the documentation for each.

I had this problem with chrome when I was working on a WordPress site. I added this code

$_SERVER['HTTPS'] = false;

into the theme's functions.php file - it asks you to log in again when you save the file but once it's logged in it works straight away.

My suggestion for google maps api v3 would be(don't think it can be done more effeciently):

gmap : {
    fitBounds: function(bounds, mapId)
    {
        //incoming: bounds - bounds object/array; mapid - map id if it was initialized in global variable before "var maps = [];"
        if (bounds==null) return false;
        maps[mapId].fitBounds(bounds);
    }
}

In the result u will fit all points in bounds in your map window.

Example works perfectly and u freely can check it here www.zemelapis.lt

Just an update on more current OS's (Vista, Win7, etc.) - the temp file path has changed may be different based on several variables. The items below are not definitive, however, they are a few I have encountered:

"temp" environment variable setting - then it would be:

%temp%\Temporary ASP.NET Files

Permissions and what application/process (VS, IIS, IIS Express) is running the .Net compiler. Accessing the C:\WINDOWS\Microsoft.NET\Framework folders requires elevated permissions and if you are not developing under an account with sufficient permissions then this folder might be used:

c:\Users\[youruserid]\AppData\Local\Temp\Temporary ASP.NET Files

There are also cases where the temp folder can be set via config for a machine or site specific using this:

<compilation tempDirectory="d:\MyTempPlace" />

I even have a funky setup at work where we don't run Admin by default, plus the IT guys have login scripts that set %temp% and I get temp files in 3 different locations depending on what is compiling things! And I'm still not certain about how these paths get picked....sigh.

Still, dthrasher is correct, you can just delete these and VS and IIS will just recompile them as needed.

if it is IIS 8 go to control panel, turn windows features on/off and enable Bad "Named pipe activation" then restart IIS. Hope the same works with IIS 7

You can get the path via fp.name. Example:

>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'

You might need os.path.basename if you want only the file name:

>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

File object docs (for Python 2) here.

If you get an error saying "Cannot Bulk load file because you don't have access right"

First make sure the path and file name you have given are correct.

then try giving the bulkadmin role to the user. To do so follow the steps :- In Object Explorer -> Security -> Logins -> Select the user (right click) -> Properties -> Server Roles -> check the bulkadmin checkbox -> OK.

This worked for me.

I'd recommend this article on CSS Tricks by Chris Coyier entitled Better Helvetica:

http://css-tricks.com/snippets/css/better-helvetica/

He basically recommends the following declaration for covering all the bases:

body {
    font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; 
    font-weight: 300;
}

Something like:

jar -xf foo.jar && find . -iname "*.class" | xargs /opt/local/bin/jad -r

maybe?

In order to pass the parameters you create new intent and put a parameter map:

Intent myIntent = new Intent(this, NewActivityClassName.class);
myIntent.putExtra("firstKeyName","FirstKeyValue");
myIntent.putExtra("secondKeyName","SecondKeyValue");
startActivity(myIntent);

In order to get the parameters values inside the started activity, you must call the get[type]Extra() on the same intent:

// getIntent() is a method from the started activity
Intent myIntent = getIntent(); // gets the previously created intent
String firstKeyName = myIntent.getStringExtra("firstKeyName"); // will return "FirstKeyValue"
String secondKeyName= myIntent.getStringExtra("secondKeyName"); // will return "SecondKeyValue"

If your parameters are ints you would use getIntExtra() instead etc. Now you can use your parameters like you normally would.

try this:

key=key.replace(/ /g,"_");

that'll do a global find/replace

Use onKeyDown event, and inside that check the key code of the key pressed by user. Key code of Enter key is 13, check the code and put the logic there.

      this.keyPress = this.keyPress.bind(this);_x000D_
   } _x000D_
 _x000D_
   handleChange(e) {_x000D_
      this.setState({ value: e.target.value });_x000D_

_x000D_
   keyPress(e){_x000D_
      if(e.keyCode == 13){_x000D_
         console.log('value', e.target.value);_x000D_
         // put the login here_x000D_

Almost all of the answers on this page rely on checking a session variable's existence to validate a user login. That is absolutely fine, but it is important to consider that the PHP session state is not unique to your application if there are multiple virtual hosts/sites on the same bare metal.

If you have two PHP applications on a webserver, both checking a user's login status with a boolean flag in a session variable called 'isLoggedIn', then a user could log into one of the applications and then automagically gain access to the second without credentials.

I suspect even the most dinosaur of commercial shared hosting wouldn't let virtual hosts share the same PHP environment in such a way that this could happen across multiple customers site's (anymore), but its something to consider in your own environments.

The very simple solution is to use a session variable that identifies the app rather than a boolean flag. e.g $SESSION["isLoggedInToExample.com"].

You can find accurate answer for this query in oracle documentation page about multiple inheritance

1. Multiple inheritance of state: Ability to inherit fields from multiple classes

   One reason why the Java programming language does not permit you to extend more than one class is to avoid the issues of multiple inheritance of state, which is the ability to inherit fields from multiple classes

   If multiple inheritance is allowed and When you create an object by instantiating that class, that object will inherit fields from all of the class's superclasses. It will cause two issues.

   1. What if methods or constructors from different super classes instantiate the same field?
   2. Which method or constructor will take precedence?

2. Multiple inheritance of implementation: Ability to inherit method definitions from multiple classes

   Problems with this approach: name conflicts and ambiguity. If a subclass and superclass contain same method name (and signature), compiler can't determine which version to invoke.

   But java supports this type of multiple inheritance with default methods, which have been introduced since Java 8 release. The Java compiler provides some rules to determine which default method a particular class uses.

   Refer to below SE post for more details on resolving diamond problem:

   What are the differences between abstract classes and interfaces in Java 8?

3. Multiple inheritance of type: Ability of a class to implement more than one interface.

   Since interface does not contain mutable fields, you do not have to worry about problems that result from multiple inheritance of state here.

1 to 10:

[0-9]{1,10}

In .NET (and not only, see the comment below) also valid (with a stipulation) this:

\d{1,10}

C#:

var regex = new Regex("^[0-9]{1,10}$", RegexOptions.Compiled);
regex.IsMatch("1"); // true
regex.IsMatch("12"); // true
..
regex.IsMatch("1234567890"); // true
regex.IsMatch(""); // false
regex.IsMatch(" "); // true
regex.IsMatch("a"); // false

Shorter answer: ignore it.

This module is the part of Postgres that processes the SQL language. The error will often pop up as part of copying a remote database, such as with a 'heroku pg:pull'. It does not overwrite your SQL processor and warns you about that.

If it happens when you try to install some package via composer just use this command COMPOSER_MEMORY_LIMIT=-1 composer require nameofpackage

I'm pretty sure GSON serializes/deserializes Maps and multiple-nested Maps (i.e. Map<String, Map<String, Object>>) just fine by default. The example provided I believe is nothing more than just a starting point if you need to do something more complex.

Check out the MapTypeAdapterFactory class in the GSON source: http://code.google.com/p/google-gson/source/browse/trunk/gson/src/main/java/com/google/gson/internal/bind/MapTypeAdapterFactory.java

So long as the types of the keys and values can be serialized into JSON strings (and you can create your own serializers/deserializers for these custom objects) you shouldn't have any issues.

This is the given array.

    int myIntegerNumbers[] = {1,2,3,4,5,6,7,8,9,10};

// If you want print the last element in the array.

    int lastNumerOfArray= myIntegerNumbers[9];
    Log.i("MyTag", lastNumerOfArray + "");

// If you want to print the number of element in the array.

    Log.i("MyTag", "The number of elements inside" +
            "the array " +myIntegerNumbers.length);

// Second method to print the last element inside the array.

    Log.i("MyTag", "The last elements inside " +
            "the array " + myIntegerNumbers[myIntegerNumbers.length-1]);

Try:

.bottom {
    position: fixed;
    bottom: 0;
}

If we want output like 'string0123456789' then we can use map function and join method of string.

>>> 'string'+"".join(map(str,xrange(10)))
'string0123456789'

If we want List of string values then use list comprehension method.

>>> ['string'+i for i in map(str,xrange(10))]
['string0', 'string1', 'string2', 'string3', 'string4', 'string5', 'string6', 'string7', 'string8', 'string9']

Note:

Use xrange() for Python 2.x

USe range() for Python 3.x

For multiselect you have to write js code, there is no settings property.

$('#js-example-basic-hide-search-multi').select2();

$('#js-example-basic-hide-search-multi').on('select2:opening select2:closing', function( event ) {
    var $searchfield = $(this).parent().find('.select2-search__field');
    $searchfield.prop('disabled', true);
});

Eclipse natively supports FTP and SSH. Aptana is not necessary.

Native FTP and SSH support in Eclipse is in the "Remote System Explorer End-User Runtime" Plugin.

Install it through Eclipse itself. These instructions may vary slightly with your version of Eclipse:

1. Go to 'Help' -> 'Install New Software' (in older Eclipses, this is called something a bit different)
2. In the 'Work with:' drop-down, select your version's plugin release site. Example: for Kepler, this is
   Kepler - http://download.eclipse.org/releases/kepler
3. In the filter field, type 'remote'.
4. Check the box next to 'Remote System Explorer End-User Runtime'
5. Click 'Next', and accept the terms. It should now download and install.
6. After install, Eclipse may want to restart.

Using it, in Eclipse:

1. Window -> Open Perspective -> (perhaps select 'Other') -> Remote System Explorer
2. File -> New -> Other -> Remote System Explorer (folder) -> Connection (or type Connection into the filter field)
3. Choose FTP from the 'Select Remote System Type' panel.
4. Fill in your FTP host info in the next panel (username and password come later).
5. In the Remote Systems panel, right-click the hostname and click 'connect'.
6. Enter username + password and you're good!
7. Well, not exactly 'good'. The RSE system is fairly unusual, but you're connected.
8. And you're one smart cookie! You'll figure out the rest.

Edit: To change the default port, follow the instructions on this page: http://ikool.wordpress.com/2008/07/25/tips-to-access-ftpssh-on-different-ports-using-eclipse-rse/

You'll need to get the innerHTML of the option, and not its value.

Edit: You'll need to get the option element first and then use innerHTML.

Use this.text instead of this.selectedIndex.

That's the HTML data attribute. See this for more detail: http://html5doctor.com/html5-custom-data-attributes/

Basically it's just a container of your custom data while still making the HTML valid. It's data- plus some unique identifier.

If you prefer utility classes to regexes, there is a method trimAllWhitespace(String) in StringUtils in the Spring Framework.

For anyone who doesn't like none of the solutions posted above like me then you can simply implement a timer yourself and stop the request execution by throwing a runtime exception. Something like below:

                  try 
                 {
                     timer.schedule(new TimerTask() {
                       @Override
                       public void run() {
                         timer.cancel();
                       }
                     }, /* specify time of the requst */ 1000);
                 }
                 catch(Exception e)
                 {
                   throw new RuntimeException("the request is taking longer than usual");
                 }

   

or preferably use the java guava timeLimiter here

In the latest Intellij ver 2020, we have an option called soft-wrap these files. Settings > Editor > General > soft-wrap these files. Check this option and add the type of files u need wrap.

Create a table view cell subclass and set it as the class of the prototype. Add the outlets to that class and connect them. Now when you configure the cell you can access the outlets.

Eric Lippert recently had a post on one of the reasons arrays should be used conservatively.

The simplest way to extract data from a DataTable when you have multiple data types (not just strings) is to use the Field<T> extension method available in the System.Data.DataSetExtensions assembly.

var id = row.Field<int>("ID");         // extract and parse int
var name = row.Field<string>("Name");  // extract string

From MSDN, the Field<T> method:

Provides strongly-typed access to each of the column values in the DataRow.

This means that when you specify the type it will validate and unbox the object.

For example:

// iterate over the rows of the datatable
foreach (var row in table.AsEnumerable())  // AsEnumerable() returns IEnumerable<DataRow>
{
    var id = row.Field<int>("ID");                           // int
    var name = row.Field<string>("Name");                    // string
    var orderValue = row.Field<decimal>("OrderValue");       // decimal
    var interestRate = row.Field<double>("InterestRate");    // double
    var isActive = row.Field<bool>("Active");                // bool
    var orderDate = row.Field<DateTime>("OrderDate");        // DateTime
}

It also supports nullable types:

DateTime? date = row.Field<DateTime?>("DateColumn");

This can simplify extracting data from DataTable as it removes the need to explicitly convert or parse the object into the correct types.

FrameLayout is not the better way to do this:

Use RelativeLayout instead. You can position the elements anywhere you like. The element that comes after, has the higher z-index than the previous one (i.e. it comes over the previous one).

Example:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent" android:layout_height="match_parent">
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/colorPrimary"
        app:srcCompat="@drawable/ic_information"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="This is a text."
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        android:layout_margin="8dp"
        android:padding="5dp"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:background="#A000"

There is actually a lot simpler and cleaner version than using request animationframe or timeouts. Iam suprised no one brought it up: the vanilla-js onload handler. If you can, use component did mount, if not, simply bind a function on the onload hanlder of the jsx component. If you want the function to run every render, also execute it before returning you results in the render function. the code would look like this:

runAfterRender = () => _x000D_
{_x000D_
  const myElem = document.getElementById("myElem")_x000D_
  if(myElem)_x000D_
  {_x000D_
    //do important stuff_x000D_
  }_x000D_
}_x000D_
_x000D_
render()_x000D_
{_x000D_
  this.runAfterRender()_x000D_
  return (_x000D_
    <div_x000D_
      onLoad = {this.runAfterRender}_x000D_
    >_x000D_
      //more stuff_x000D_
    </div>_x000D_
  )_x000D_
}

}

I keep hitting this answer. But none of them list the easiest solution for xsltproc (and probably most XSLT 1.0 processors):

1. Add the exslt strings name to the stylesheet, i.e.:

<xsl:stylesheet
  version="1.0"
  xmlns:str="http://exslt.org/strings"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

2. Then use it like:

<xsl:value-of select="str:replace(., ' ', '')"/>

I faced this issue once and was able to resolve it by fixing of my /etc/hosts. It just was unable to resolve localhost name... Details are here: http://itvictories.com/node/6

In fact, there is 99% that error related to /etc/hosts file

X server just unable to resolve localhost and all consequent actions just fails.

Please be sure that you have a record like

127.0.0.1 localhost

in your /etc/hosts file.

You can use either jQuery Autocomplete or ASP.NET AJAX Toolkit Autocomplete

You don't mention the API version, but since API 11 there's the method WebViewClient.shouldInterceptRequest

Maybe this could help?

I do something very similar to you.

I'll usually include a DEBUG param that defaults to false and I can set to true at run time. Then wrap the debug statements into an "If DEBUG" block.

I also use a logging table with many of my jobs so that I can review processes and timing. My Debug code gets output there as well. I include the calling param name, a brief description, row counts affected (if appropriate), a comments field and a time stamp.

Good debugging tools is one of the sad failings of all SQL platforms.

If you have multiple occurrences of an element name, then you have to use forEach().

html

  <input type="checkbox" name="delete" id="flizzit" />
  <input type="checkbox" name="delete" id="floo" />
  <input type="checkbox" name="delete" id="flum" />
  <input type="submit" value="Save"  onClick={evt => saveAction(evt)}></input>

js

const submitAction = (evt) => {
  evt.preventDefault();
  const dels = evt.target.parentElement.delete;
  const deleted = [];
  dels.forEach((d) => { if (d.checked) deleted.push(d.id); });
  window.alert(deleted.length);
};

Note the dels in this case is a RadioNodeList, not an array, and is not an Iterable. The forEach()is a built-in method of the list class. You will not be able to use a map() or reduce() here.

There are many good answers here but you should avoid at all cost to pass untrusted variables to subprocess using shell=True as this is a security risk. The variables can escape to the shell and run arbitrary commands! If you just can't avoid it at least use python3's shlex.quote() to escape the string (if you have multiple space-separated arguments, quote each split instead of the full string).

shell=False is always the default where you pass an argument array.

Now the safe solutions...

Method #1

Change your own process's environment - the new environment will apply to python itself and all subprocesses.

os.environ['LD_LIBRARY_PATH'] = 'my_path'
command = ['sqsub', '-np', var1, '/homedir/anotherdir/executable']
subprocess.check_call(command)

Method #2

Make a copy of the environment and pass is to the childen. You have total control over the children environment and won't affect python's own environment.

myenv = os.environ.copy()
myenv['LD_LIBRARY_PATH'] = 'my_path'
command = ['sqsub', '-np', var1, '/homedir/anotherdir/executable']
subprocess.check_call(command, env=myenv)

Method #3

Unix only: Execute env to set the environment variable. More cumbersome if you have many variables to modify and not portabe, but like #2 you retain full control over python and children environments.

command = ['env', 'LD_LIBRARY_PATH=my_path', 'sqsub', '-np', var1, '/homedir/anotherdir/executable']
subprocess.check_call(command)

Of course if var1 contain multiple space-separated argument they will now be passed as a single argument with spaces. To retain original behavior with shell=True you must compose a command array that contain the splitted string:

command = ['sqsub', '-np'] + var1.split() + ['/homedir/anotherdir/executable']

The easiest way is to import the certificate into a sample firefox-profile and then copy the cert8.db to the users you want equip with the certificate.

First import the certificate by hand into the firefox profile of the sample-user. Then copy

• /home/${USER}/.mozilla/firefox/${randomalphanum}.default/cert8.db (Linux/Unix)

• %userprofile%\Application Data\Mozilla\Firefox\Profiles\%randomalphanum%.default\cert8.db (Windows)

into the users firefox-profiles. That's it. If you want to make sure, that new users get the certificate automatically, copy cert8.db to:

• /etc/firefox-3.0/profile (Linux/Unix)

• %programfiles%\firefox-installation-folder\defaults\profile (Windows)

This topic is old but if other people like me search a solution, this is a solution that I have found:

Public Function DBStats() As Boolean
    On Error GoTo errorHandler
        If Not IsNull(myBase.Version) Then 
            DBStats = True
        End If
        Exit Function
    errorHandler:
        DBStats = False  
End Function

So "myBase" is a Database Object, I have made a class to access to database (class with insert, update etc...) and on the module the class is use declare in an object (obviously) and I can test the connection with "[the Object].DBStats":

Dim BaseAccess As New myClass
BaseAccess.DBOpen 'I open connection
Debug.Print BaseAccess.DBStats ' I test and that tell me true
BaseAccess.DBClose ' I close the connection
Debug.Print BaseAccess.DBStats ' I test and tell me false

Edit : In DBOpen I use "OpenDatabase" and in DBClose I use ".Close" and "set myBase = nothing" Edit 2: In the function, if you are not connect, .version give you an error so if aren't connect, the errorHandler give you false

HTTParty makes this a bit easier I think (and works with nested json etc, which didn't seem to work in other examples I've seen.

require 'httparty'
HTTParty.post("http://localhost:3000/api/v1/users", body: {user: {email: '[email protected]', password: 'secret'}}).body

In our case it was an empty AndroidManifest.xml.

While upgrading Eclispe we ran into the usual trouble, and AndroidManifest.xml must have been checked into SVN by the build script after being clobbered.

Found it by compiling from inside Eclipse, instead of from the command line.

Check your project by running gcloud config list Then gcloud config set "project name"

You don't need to bind the submit event on the click of the submit button just bind the submit event and it will capture the submit event no mater how it gets triggered.

Think what you are wanting is to submit the sortable like you would via ajax. Try doing something like this:

var form = $('#event').submit(function () {
    $.each($('#attendance').sortable('toArray'),function(i, value){
        $("<input>").attr({
            'type':'hidden',
            'name':'attendace['+i+']'
        }).val(value).appendTo(form);
    });
});

Typically, all you'll ever need is to carry some state between these two requests. There's actually a really funky way to do this which doesn't rely on JavaScript (think <noscript/>).

Set-Cookie: name=value; Max-Age=120; Path=/redirect.html

With that cookie there, you can in the following request to /redirect.html retrieve the name=value info, you can store any kind of information in this name/value pair string, up to say 4K of data (typical cookie limit). Of course you should avoid this and store status codes and flag bits instead.

Upon receiving this request you in return respond with a delete request for that status code.

Set-Cookie: name=value; Max-Age=0; Path=/redirect.html

My HTTP is a bit rusty I've been going trough RFC2109 and RFC2965 to figure how reliable this really is, preferably I would want the cookie to round trip exactly once but that doesn't seem to be possible, also, third-party cookies might be a problem for you if you are relocating to another domain. This is still possible but not as painless as when you're doing stuff within your own domain.

The problem here is concurrency, if a power user is using multiple tabs and manages to interleave a couple of requests belonging to the same session (this is very unlikely, but not impossible) this may lead to inconsistencies in your application.

It's the <noscript/> way of doing HTTP round trips without meaningless URLs and JavaScript

I provide this code as a prof of concept: If this code is run in a context that you are not familiar with I think you can work out what part is what.

The idea is that you call Relocate with some state when you redirect, and the URL which you relocated calls GetState to get the data (if any).

const string StateCookieName = "state";

static int StateCookieID;

protected void Relocate(string url, object state)
{
    var key = "__" + StateCookieName + Interlocked
        .Add(ref StateCookieID, 1).ToInvariantString();

    var absoluteExpiration = DateTime.Now
        .Add(new TimeSpan(120 * TimeSpan.TicksPerSecond));

    Context.Cache.Insert(key, state, null, absoluteExpiration,
        Cache.NoSlidingExpiration);

    var path = Context.Response.ApplyAppPathModifier(url);

    Context.Response.Cookies
        .Add(new HttpCookie(StateCookieName, key)
        {
            Path = path,
            Expires = absoluteExpiration
        });

    Context.Response.Redirect(path, false);
}

protected TData GetState<TData>()
    where TData : class
{
    var cookie = Context.Request.Cookies[StateCookieName];
    if (cookie != null)
    {
        var key = cookie.Value;
        if (key.IsNonEmpty())
        {
            var obj = Context.Cache.Remove(key);

            Context.Response.Cookies
                .Add(new HttpCookie(StateCookieName)
                { 
                    Path = cookie.Path, 
                    Expires = new DateTime(1970, 1, 1) 
                });

            return obj as TData;
        }
    }
    return null;
}

The output of EXPLAIN PLAN is a debug output from Oracle's query optimiser. The COST is the final output of the Cost-based optimiser (CBO), the purpose of which is to select which of the many different possible plans should be used to run the query. The CBO calculates a relative Cost for each plan, then picks the plan with the lowest cost.

(Note: in some cases the CBO does not have enough time to evaluate every possible plan; in these cases it just picks the plan with the lowest cost found so far)

In general, one of the biggest contributors to a slow query is the number of rows read to service the query (blocks, to be more precise), so the cost will be based in part on the number of rows the optimiser estimates will need to be read.

For example, lets say you have the following query:

SELECT emp_id FROM employees WHERE months_of_service = 6;

(The months_of_service column has a NOT NULL constraint on it and an ordinary index on it.)

There are two basic plans the optimiser might choose here:

• Plan 1: Read all the rows from the "employees" table, for each, check if the predicate is true (months_of_service=6).
• Plan 2: Read the index where months_of_service=6 (this results in a set of ROWIDs), then access the table based on the ROWIDs returned.

Let's imagine the "employees" table has 1,000,000 (1 million) rows. Let's further imagine that the values for months_of_service range from 1 to 12 and are fairly evenly distributed for some reason.

The cost of Plan 1, which involves a FULL SCAN, will be the cost of reading all the rows in the employees table, which is approximately equal to 1,000,000; but since Oracle will often be able to read the blocks using multi-block reads, the actual cost will be lower (depending on how your database is set up) - e.g. let's imagine the multi-block read count is 10 - the calculated cost of the full scan will be 1,000,000 / 10; Overal cost = 100,000.

The cost of Plan 2, which involves an INDEX RANGE SCAN and a table lookup by ROWID, will be the cost of scanning the index, plus the cost of accessing the table by ROWID. I won't go into how index range scans are costed but let's imagine the cost of the index range scan is 1 per row; we expect to find a match in 1 out of 12 cases, so the cost of the index scan is 1,000,000 / 12 = 83,333; plus the cost of accessing the table (assume 1 block read per access, we can't use multi-block reads here) = 83,333; Overall cost = 166,666.

As you can see, the cost of Plan 1 (full scan) is LESS than the cost of Plan 2 (index scan + access by rowid) - which means the CBO would choose the FULL scan.

If the assumptions made here by the optimiser are true, then in fact Plan 1 will be preferable and much more efficient than Plan 2 - which disproves the myth that FULL scans are "always bad".

The results would be quite different if the optimiser goal was FIRST_ROWS(n) instead of ALL_ROWS - in which case the optimiser would favour Plan 2 because it will often return the first few rows quicker, at the cost of being less efficient for the entire query.

Use column-width property of css like below

<ul style="column-width:135px">

The line-continuation will fail if you have whitespace (spaces or tab characters[1]) after the backslash and before the newline. With no such whitespace, your example works fine for me:

$ cat test.sh
if ! fab --fabfile=.deploy/fabfile.py \
   --forward-agent \
   --disable-known-hosts deploy:$target; then
     echo failed
else
     echo succeeded
fi

$ alias fab=true; . ./test.sh
succeeded
$ alias fab=false; . ./test.sh
failed

Some detail promoted from the comments: the line-continuation backslash in the shell is not really a special case; it is simply an instance of the general rule that a backslash "quotes" the immediately-following character, preventing any special treatment it would normally be subject to. In this case, the next character is a newline, and the special treatment being prevented is terminating the command. Normally, a quoted character winds up included literally in the command; a backslashed newline is instead deleted entirely. But otherwise, the mechanism is the same. Most importantly, the backslash only quotes the immediately-following character; if that character is a space or tab, you just get a literal space or tab, and any subsequent newline remains unquoted.

[1] or carriage returns, for that matter, as Czechnology points out. Bash does not get along with Windows-formatted text files, not even in WSL. Or Cygwin, but at least their Bash port has added a set -o igncr option that you can set to make it carriage-return-tolerant.

Definitively:

template<class T>
T ror(T x, unsigned int moves)
{
  return (x >> moves) | (x << sizeof(T)*8 - moves);
}

In Firefox the onchange fires only when you tab or else click outside the input field. The same is true of Onblur. The difference is that onblur will fire whether you changed anything in the field or not. It is possible that ENTER will fire one or both of these, but you wouldn't know that if you disable the ENTER in your forms to prevent unexpected submits.

Clearly! We can make a function to return a CSS class name with following fully example.

CSS

<style>
    .Red {
        color: Red;
    }
    .Yellow {
        color: Yellow;
    }
      .Blue {
        color: Blue;
    }
      .Green {
        color: Green;
    }
    .Gray {
        color: Gray;
    }
     .b{
         font-weight: bold;
    }
</style>

JS

<script>
    angular.module('myapp', [])
            .controller('ExampleController', ['$scope', function ($scope) {
                $scope.MyColors = ['It is Red', 'It is Yellow', 'It is Blue', 'It is Green', 'It is Gray'];
                $scope.getClass = function (strValue) {
                    if (strValue == ("It is Red"))
                        return "Red";
                    else if (strValue == ("It is Yellow"))
                        return "Yellow";
                    else if (strValue == ("It is Blue"))
                        return "Blue";
                    else if (strValue == ("It is Green"))
                        return "Green";
                    else if (strValue == ("It is Gray"))
                        return "Gray";
                }
        }]);
</script>

And then

<body ng-app="myapp" ng-controller="ExampleController">

<h2>AngularJS ng-class if example</h2>
<ul >
    <li ng-repeat="icolor in MyColors" >
        <p ng-class="[getClass(icolor), 'b']">{{icolor}}</p>
    </li>
</ul>
<hr/>
<p>Other way using : ng-class="{'class1' : expression1, 'class2' : expression2,'class3':expression2,...}"</p>
<ul>
    <li ng-repeat="icolor in MyColors">
        <p ng-class="{'Red':icolor=='It is Red','Yellow':icolor=='It is Yellow','Blue':icolor=='It is Blue','Green':icolor=='It is Green','Gray':icolor=='It is Gray'}" class="b">{{icolor}}</p>
    </li>
</ul>

@Jon's :parse/:endparse scheme is a great start, and he has my gratitude for the initial pass, but if you think that the Windows torturous batch system would let you off that easy… well, my friend, you are in for a shock. I have spent the whole day with this devilry, and after much painful research and experimentation I finally managed something viable for a real-life utility.

Let us say that we want to implement a utility foobar. It requires an initial command. It has an optional parameter --foo which takes an optional value (which cannot be another parameter, of course); if the value is missing it defaults to default. It also has an optional parameter --bar which takes a required value. Lastly it can take a flag --baz with no value allowed. Oh, and these parameters can come in any order.

In other words, it looks like this:

foobar <command> [--foo [<fooval>]] [--bar <barval>] [--baz]

Complicated? No, that seems pretty typical of real life utilities. (git anyone?)

Without further ado, here is a solution:

@ECHO OFF
SETLOCAL
REM FooBar parameter demo

SET CMD=%~1

IF "%CMD%" == "" (
  GOTO usage
)
SET FOO=

Yes, it really is that bad. See my similar post at https://stackoverflow.com/a/50653047/421049, where I provide more analysis of what is going on in the logic, and why I used certain constructs.

Hideous. Most of that I had to learn today. And it hurt.

This works in MySQL all versions and Amazon RDS Aurora:

INSERT INTO my_table SELECT 0,tmp.* FROM tmp;

or

Setting the index column to NULL and then doing the INSERT.

But not in MariaDB, I tested version 10.

The easiest thing that makes it work for me is calling a shell command in Python.

If your images are stored such as dummy_image_1.png, dummy_image_2.png ... dummy_image_N.png, then you can use the function:

import subprocess
def grid2gif(image_str, output_gif):
    str1 = 'convert -delay 100 -loop 1 ' + image_str  + ' ' + output_gif
    subprocess.call(str1, shell=True)

Just execute:

grid2gif("dummy_image*.png", "my_output.gif")

This will construct your gif file my_output.gif.

You are supposed to download the jar files that contain these libraries. Libraries may be used by adding them to the classpath.

For Commons Net you need to download the binary files from Commons Net download page. Then you have to extract the file and add the commons-net-2-2.jar file to some location where you can access it from your application e.g. to /lib.

If you're running your application from the command-line you'll have to define the classpath in the java command: java -cp .;lib/commons-net-2-2.jar myapp. More info about how to set the classpath can be found from Oracle documentation. You must specify all directories and jar files you'll need in the classpath excluding those implicitely provided by the Java runtime. Notice that there is '.' in the classpath, it is used to include the current directory in case your compiled class is located in the current directory.

For more advanced reading, you might want to read about how to define the classpath for your own jar files, or the directory structure of a war file when you're creating a web application.

If you are using an IDE, such as Eclipse, you have to remember to add the library to your build path before the IDE will recognize it and allow you to use the library.

A while loop can be simulated in cmd.exe with:

:still_more_files
    if %countfiles% leq 21 (
        rem change countfile here
        goto :still_more_files
    )

For example, the following script:

    @echo off
    setlocal enableextensions enabledelayedexpansion
    set /a "x = 0"

:more_to_process
    if %x% leq 5 (
        echo %x%
        set /a "x = x + 1"
        goto :more_to_process
    )

    endlocal

outputs:

0
1
2
3
4
5

For your particular case, I would start with the following. Your initial description was a little confusing. I'm assuming you want to delete files in that directory until there's 20 or less:

    @echo off
    set backupdir=c:\test

:more_files_to_process
    for /f %%x in ('dir %backupdir% /b ^| find /v /c "::"') do set num=%%x
    if %num% gtr 20 (
        cscript /nologo c:\deletefile.vbs %backupdir%
        goto :more_files_to_process
    )

Save into a file

Car car = new Car();
car.Name = "Some fancy car";
MemoryStream stream = Serializer.SerializeToStream(car);
System.IO.File.WriteAllBytes(fileName, stream.ToArray());

Load from a file

using (var stream = new MemoryStream(System.IO.File.ReadAllBytes(fileName)))
{
    Car car = (Car)Serializer.DeserializeFromStream(stream);
}

where

using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;

namespace Serialization
{
    public class Serializer
    {
        public static MemoryStream SerializeToStream(object o)
        {
            MemoryStream stream = new MemoryStream();
            IFormatter formatter = new BinaryFormatter();
            formatter.Serialize(stream, o);
            return stream;
        }

        public static object DeserializeFromStream(MemoryStream stream)
        {
            IFormatter formatter = new BinaryFormatter();
            stream.Seek(0, SeekOrigin.Begin);
            object o = formatter.Deserialize(stream);
            return o;
        }
    }
}

There is no problem with displaying HTML code in blade templates.

For test, you can add to routes.php only one route:

Route::get('/', function () {

        $data = new stdClass();
        $data->page_desc
            = '<strong>aaa</strong><em>bbb</em>
               <p>New paragaph</p><script>alert("Hello");</script>';

        return View::make('hello')->with('content', $data);
    }
);

and in hello.blade.php file:

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
</head>
<body>

{{ $content->page_desc }}

</body>
</html>

For the following code you will get output as on image

So probably page_desc in your case is not what you expect. But as you see it can be potential dangerous if someone uses for example '` tag so you should probably in your route before assigning to blade template filter some tags

EDIT

I've also tested it with putting the same code into database:

Route::get('/', function () {

        $data = User::where('id','=',1)->first();

        return View::make('hello')->with('content', $data);
    }
);

Output is exactly the same in this case

Edit2

I also don't know if Pages is your model or it's a vendor model. For example it can have accessor inside:

public function getPageDescAttribute($value)
{
    return htmlspecialchars($value);
}

and then when you get page_desc attribute you will get modified page_desc with htmlspecialchars. So if you are sure that data in database is with raw html (not escaped) you should look at this Pages class

All objects in java are passed to functions by reference copy except primitives.

In effect, this means that you are sending a copy of the pointer to the original object rather than a copy of the object itself.

Please leave a comment if you want an example to understand this.

I encountered the same issue using Spring Boot 2.0.5.RELEASE on Java 11.

Adding javax.xml.bind:jaxb-api:2.3.0 alone did not fix the problem. I also had to update Spring Boot to the latest Milestone 2.1.0.M2, so I assume this will be fixed in the next official release.

Here is how I would do it using vanilla JS

<form id="myform" method="POST" action="xxx">
    <!-- your stuff here -->
    <a href="javascript:void()" onclick="document.getElementById('myform').submit();>Ponies await!</a>
</form>

You can play with the return falses and href="#" vs void and whatever you need to but this method worked for me in Chrome 18, IE 9 and Firefox 14 and the rest depends on your javascript mostly.

I was just having a similar situation in which my code potentially throws a number of different exceptions that I just wanted to rethrow. The solution described above was not working for me, because Eclipse told me that throw e; leads to an unhandeled exception, so I just did this:

try
{
...
} catch (NoSuchMethodException | SecurityException | IllegalAccessException e) {                    
    throw new RuntimeException(e.getClass().getName() + ": " + e.getMessage() + "\n" + e.getStackTrace().toString());
}

Worked for me....:)

request.getSession() or request.getSession(true) both will return a current session only . if current session will not exist then it will create a new session.

I actually just resolved an issue I was having by swapping around the order that I was altering the properties in. For example I was changing the attribute first but I actually had to remove the class and add the new class before modifying the attributes. I'm not sure why it worked but it did. So something to try would be to change from $("XXXX").attr('something').removeClass( "class" ).addClass( "newClass" ) to $("XXXX").removeClass( "class" ).addClass( "newClass" ).attr('something').

You mention Haxe/NME but you seem to instinctively dislike it. However, my experience with it has been very positive. Sure, the API is a reimplementation of the Flash API, but you're not limited to targeting Flash, you can also compile to HTML5 or native Windows, Mac, iOS and Android apps. Haxe is a pleasant, modern language similar to Java or C#.

If you're interested, I've written a bit about my experience using Haxe/NME: link

yum install glibc.i686

install this.

$scope.countDown = 30;
var timer;
$scope.countTimer = function () {
    var time = $timeout(function () {
         timer = setInterval(function () {
             if ($scope.countDown > 0) {
                 $scope.countDown--;
            } else {
                clearInterval(timer);
                $window.location.href = '/Logoff';
            }
            $scope.$apply();
        }, 1000);
    }, 0);
}

$scope.stop= function () {
    clearInterval(timer);
    
}

IN HTML:

<button type="submit" ng-click="countTimer()">Start</button>
<button type="submit" ng-click="stop()">Clear</button>
                 
                
              

There are multiple possible reasons for django not detecting what to migrate during the makemigrations command.

1. migration folder You need a migrations package in your app.
2. INSTALLED_APPS You need your app to be specified in the INSTALLED_APPS .dict
3. Verbosity start by running makemigrations -v 3 for verbosity. This might shed some light on the problem.
4. Full path In INSTALLED_APPS it is recommended to specify the full module app config path 'apply.apps.MyAppConfig'
5. --settings you might want to make sure the correct settings file is set: manage.py makemigrations --settings mysite.settings
6. specify app name explicitly put the app name in manage.py makemigrations myapp - that narrows down the migrations for the app alone and helps you isolate the problem.

7. model meta check you have the right app_label in your model meta

8. Debug django debug django core script. makemigrations command is pretty much straight forward. Here's how to do it in pycharm. change your script definition accordingly (ex: makemigrations --traceback myapp)

Multiple databases:

• Db Router when working with django db router, the router class (your custom router class) needs to implement the allow_syncdb method.

makemigrations always creates migrations for model changes, but if allow_migrate() returns False,

You can't access Temporary Tables from within a SQL Function. You will need to use table variables so essentially:

ALTER FUNCTION FnGetCompanyIdWithCategories()
RETURNS  @rtnTable TABLE 
(
    -- columns returned by the function
    ID UNIQUEIDENTIFIER NOT NULL,
    Name nvarchar(255) NOT NULL
)
AS
BEGIN
DECLARE @TempTable table (id uniqueidentifier, name nvarchar(255)....)

insert into @myTable 
select from your stuff

--This select returns data
insert into @rtnTable
SELECT ID, name FROM @mytable 
return
END

Edit

Based on comments to this question here is my recommendation. You want to join the results of either a procedure or table-valued function in another query. I will show you how you can do it then you pick the one you prefer. I am going to be using sample code from one of my schemas, but you should be able to adapt it. Both are viable solutions first with a stored procedure.

declare @table as table (id int, name nvarchar(50),templateid int,account nvarchar(50))

insert into @table
execute industry_getall

select * 
from @table 
inner join [user] 
    on account=[user].loginname

In this case, you have to declare a temporary table or table variable to store the results of the procedure. Now Let's look at how you would do this if you were using a UDF

select *
from fn_Industry_GetAll()
inner join [user] 
    on account=[user].loginname

As you can see the UDF is a lot more concise easier to read, and probably performs a little bit better since you're not using the secondary temporary table (performance is a complete guess on my part).

If you're going to be reusing your function/procedure in lots of other places, I think the UDF is your best choice. The only catch is you will have to stop using #Temp tables and use table variables. Unless you're indexing your temp table, there should be no issue, and you will be using the tempDb less since table variables are kept in memory.

SUMIF didn't worked for me, had to use SUMIFS.

=SUMIFS(TableAmount,TableMonth,"January")

TableAmount is the table to sum the values, TableMonth the table where we search the condition and January, of course, the condition to meet.

Hope this can help someone!

When I read your question, I thought your were on Oracle DB until I saw the tag 'MySQL'. Anyway, for people working with Oracle here is the way:

SELECT *
FROM table
where timestamp = to_timestamp('21.08.2017 09:31:57', 'dd-mm-yyyy hh24:mi:ss');

<?php
$args     = array( 'post_type' => 'product', 'category' => 34, 'posts_per_page' => -1 );
$products = get_posts( $args ); 
?>

This should grab all the products you want, I may have the post type wrong though I can't quite remember what woo-commerce uses for the post type. It will return an array of products

if your data define line you just have to prove that they are not parallel. To do this you can compute

alpha = float(y2 - y1) / (x2 - x1).

If this coefficient is equal for both Line1 and Line2, it means the line are parallel. If not, it means they will intersect.

If they are parallel you then have to prove that they are not the same. For that, you compute

beta = y1 - alpha*x1

If beta is the same for Line1 and Line2,it means you line intersect as they are equal

If they are segment, you still have to compute alpha and beta as described above for each Line. Then you have to check that (beta1 - beta2) / (alpha1 - alpha2) is greater than Min(x1_line1, x2_line1) and less than Max(x1_line1, x2_line1)

Singleton is a pattern and can be used or abused just like any other tool.

The bad part of a singleton is generally the user (or should I say the inappropriate use of a singleton for things it is not designed to do). The biggest offender is using a singleton as a fake global variable.

Since state isn't tightly coupled with component instance in functional components, previous state cannot be reached in useEffect without saving it first, for instance, with useRef. This also means that state update was possibly incorrectly implemented in wrong place because previous state is available inside setState updater function.

This is a good use case for useReducer which provides Redux-like store and allows to implement respective pattern. State updates are performed explicitly, so there's no need to figure out which state property is updated; this is already clear from dispatched action.

Here's an example what it may look like:

function reducer({ sendAmount, receiveAmount, rate }, action) {
  switch (action.type) {
    case "sendAmount":
      sendAmount = action.payload;
      return {
        sendAmount,
        receiveAmount: sendAmount * rate,
        rate
      };
    case "receiveAmount":
      receiveAmount = action.payload;
      return {
        sendAmount: receiveAmount / rate,
        receiveAmount,
        rate
      };
    case "rate":
      rate = action.payload;
      return {
        sendAmount: receiveAmount ? receiveAmount / rate : sendAmount,
        receiveAmount: sendAmount ? sendAmount * rate : receiveAmount,
        rate
      };
    default:
      throw new Error();
  }
}

function handleChange(e) {
  const { name, value } = e.target;
  dispatch({
    type: name,
    payload: value
  });
}

...
const [state, dispatch] = useReducer(reducer, {
  rate: 2,
  sendAmount: 0,
  receiveAmount: 0
});
...

Are you sure that floated block-level elements are the best solution to this problem?

Often with CSS difficulties in my experience it turns out that the reason I can't see a way of doing the thing I want is that I have got caught in a tunnel-vision with regard to my markup ( thinking "how can I make these elements do this?" ) rather than going back and looking at what exactly it is I need to achieve and maybe reworking my html slightly to facilitate that.

System.IO.File.WriteAllText (@"D:\path.txt", contents);

• If the file does not exist, this creates it.

You need to install this extension to Visual Studio 2017/2019 in order to get access to the Installer Projects.

According to the page:

This extension provides the same functionality that currently exists in Visual Studio 2015 for Visual Studio Installer projects. To use this extension, you can either open the Extensions and Updates dialog, select the online node, and search for "Visual Studio Installer Projects Extension," or you can download directly from this page.

Once you have finished installing the extension and restarted Visual Studio, you will be able to open existing Visual Studio Installer projects, or create new ones.

I solved it by deleting "/.idea/libraries" from project. Thanks

Maybe it is easier to convert the Date into the actual integer 20110506105524 and then convert this into a string:

function printDate() {
    var temp = new Date();
    var dateInt =
        ((((temp.getFullYear() * 100 + 
            temp.getMonth() + 1) * 100 + 
           temp.getDate()) * 100 +
          temp.getHours()) * 100 + 
         temp.getMinutes()) * 100 + 
        temp.getSeconds();

    debug ( '' + dateInt );  // convert to String
}

When temp.getFullYear() < 1000 the result will be one (or more) digits shorter.

Caution: this wont work with millisecond precision (i.e. 17 digits) since Number.MAX_SAFE_INTEGER is 9007199254740991 which is only 16 digits.

Yes, bool. It's not exactly the same -- '0' is True, but None, False, [], 0, 0.0, and "" are all False.

bool is used implicitly when you evaluate an object in a condition like an if or while statement, conditional expression, or with a boolean operator.

If you wanted to handle strings containing numbers as PHP does, you could do something like:

def empty(value):
    try:
        value = float(value)
    except ValueError:
        pass
    return bool(value)

Try this:

^[0-9]{4,6}$

{4,6} = between 4 and 6 characters, inclusive.

Uninstall Python 3.7 for Windows, and only install Python 3.6.0 then you will have no problem or receive the error message:

import tensorflow as tf ModuleNotFoundError: No module named 'tensorflow'

A few examples follow, going from basic through to adding transformations after the request and/or error handling:

Basic:

// Implementation code where T is the returned data shape
function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json<T>()
    })

}

// Consumer
api<{ title: string; message: string }>('v1/posts/1')
  .then(({ title, message }) => {
    console.log(title, message)
  })
  .catch(error => {
    /* show error message */
  })

Data transformations:

Often you may need to do some tweaks to the data before its passed to the consumer, for example, unwrapping a top level data attribute. This is straight forward:

function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json<{ data: T }>()
    })
    .then(data => { /* <-- data inferred as { data: T }*/
      return data.data
    })
}

// Consumer - consumer remains the same
api<{ title: string; message: string }>('v1/posts/1')
  .then(({ title, message }) => {
    console.log(title, message)
  })
  .catch(error => {
    /* show error message */
  })

Error handling:

I'd argue that you shouldn't be directly error catching directly within this service, instead, just allowing it to bubble, but if you need to, you can do the following:

function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json<{ data: T }>()
    })
    .then(data => {
      return data.data
    })
    .catch((error: Error) => {
      externalErrorLogging.error(error) /* <-- made up logging service */
      throw error /* <-- rethrow the error so consumer can still catch it */
    })
}

// Consumer - consumer remains the same
api<{ title: string; message: string }>('v1/posts/1')
  .then(({ title, message }) => {
    console.log(title, message)
  })
  .catch(error => {
    /* show error message */
  })

Edit

There has been some changes since writing this answer a while ago. As mentioned in the comments, response.json<T> is no longer valid. Not sure, couldn't find where it was removed.

For later releases, you can do:

// Standard variation
function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json() as Promise<T>
    })
}


// For the "unwrapping" variation

function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json() as Promise<{ data: T }>
    })
    .then(data => {
        return data.data
    })
}

For me, this ended up being because I had the wrong SDK level installed (new version of Android Studio installed the SDK for Android 10, whereas I have a device that runs only Android 8.1). While Android Studio would "recognize" the device and display a string in the "devices" menu instead of just saying that no device was connected, installing the right SDK level for my device ended up changing the string to something recognizable (my device's model name) and allowed me to actually run my app over ADB.

@Arnon Rotem-Gal-Oz answer is right for the most part. But I would like to point out the difference between df['year']=df['year'].astype(int) and df.year.astype(int). df.year.astype(int) returns a view of the dataframe and doesn't not explicitly change the type, atleast in pandas 0.24.2. df['year']=df['year'].astype(int) explicitly change the type because it's an assignment. I would argue that this is the safest way to permanently change the dtype of a column.

Example:

df = pd.DataFrame({'Weed': ['green crack', 'northern lights', 'girl scout cookies'], 'Qty':[10,15,3]}) df.dtypes

Weed object, Qty int64

df['Qty'].astype(str) df.dtypes

Weed object, Qty int64

Even setting the inplace arg to True doesn't help at times. I don't know why this happens though. In most cases inplace=True equals an explicit assignment.

df['Qty'].astype(str, inplace = True) df.dtypes

Weed object, Qty int64

Now the assignment,

df['Qty'] = df['Qty'].astype(str) df.dtypes

Weed object, Qty object

The accepted answer by Adam (flex: 1 1 0) works perfectly for flexbox containers whose width is either fixed, or determined by an ancestor. Situations where you want the children to fit the container.

However, you may have a situation where you want the container to fit the children, with the children equally sized based on the largest child. You can make a flexbox container fit its children by either:

• setting position: absolute and not setting width or right, or
• place it inside a wrapper with display: inline-block

For such flexbox containers, the accepted answer does NOT work, the children are not sized equally. I presume that this is a limitation of flexbox, since it behaves the same in Chrome, Firefox and Safari.

The solution is to use a grid instead of a flexbox.

Demo: https://codepen.io/brettdonald/pen/oRpORG

<p>Normal scenario — flexbox where the children adjust to fit the container — and the children are made equal size by setting {flex: 1 1 0}</p>

<div id="div0">
  <div>
    Flexbox
  </div>
  <div>
    Width determined by viewport
  </div>
  <div>
    All child elements are equal size with {flex: 1 1 0}
  </div>
</div>

<p>Now we want to have the container fit the children, but still have the children all equally sized, based on the largest child. We can see that {flex: 1 1 0} has no effect.</p>

<div class="wrap-inline-block">
<div id="div1">
  <div>
    Flexbox
  </div>
  <div>
    Inside inline-block
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>
</div>

<div id="div2">
  <div>
    Flexbox
  </div>
  <div>
    Absolutely positioned
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>

<br><br><br><br><br><br>
<p>So let's try a grid instead. Aha! That's what we want!</p>

<div class="wrap-inline-block">
<div id="div3">
  <div>
    Grid
  </div>
  <div>
    Inside inline-block
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>
</div>

<div id="div4">
  <div>
    Grid
  </div>
  <div>
    Absolutely positioned
  </div>
  <div>
    We want all children to be the size of this text
  </div>

You can also do this if you want to play around with pandas. However, I like punchagan's way.

# replicating your dataframe
lake = pd.DataFrame({'co tp': ['DE Lake', 'Forest', 'FR Lake', 'Forest'], 
                 'area': [10, 20, 30, 40], 
                 'count': [7, 5, 2, 3]})
lake.set_index('co tp', inplace=True)

# to get key value using pandas
area_dict = lake.set_index('area').T.to_dict('records')[0]
print(area_dict)

output: {10: 7, 20: 5, 30: 2, 40: 3}

3 easy steps to run your PHP program is:

1. The easiest way is to install MAMP!

2. Do a 2-minute setup of MAMP.

3. Open the localhost server in your browser at the created port to see your program up and runing!

Remove the canvas dom and add in again.

function renderChart(label,data){

    $("#canvas-wrapper").html("").html('<canvas id="storeSends"></canvas>');
    var lineChartData = {
        labels : label,
        datasets : [
            {
                fillColor : "rgba(49, 195, 166, 0.2)",
                strokeColor : "rgba(49, 195, 166, 1)",
                pointColor : "rgba(49, 195, 166, 1)",
                pointStrokeColor : "#fff",
                data : data
            }
        ]

    }
    var canvas = document.getElementById("storeSends");
    var ctx = canvas.getContext("2d");

    myLine = new Chart(ctx).Line(lineChartData, {
        responsive: true,
        maintainAspectRatio: false
    });
}

Instead of this code, you should call GetHashCode(), which will return a (hopefully-)unique value for each instance.

You can also use the ObjectIDGenerator class, which is guaranteed to be unique.

java: Java application executor which is associated with a console to display output/errors

javaw: (Java windowed) application executor not associated with console. So no display of output/errors. It can be used to silently push the output/errors to text files. It is mostly used to launch GUI-based applications.

javaws: (Java web start) to download and run the distributed web applications. Again, no console is associated.

I got below error :

Found the synthetic property @collapse. Please include either "BrowserAnimationsModule" or "NoopAnimationsModule" in your application.

I follow the accepted answer by Ploppy and it resolved my problem.

Here are the steps:

1.
    import { trigger, state, style, transition, animate } from '@angular/animations';
    Or 
    import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

2. Define the same in the import array in the root module.

It will resolve the error. Happy coding!!

I had similar issue. Try use the HQL editor. It will display you the SQL (as you have a SQL grammar exception). Copy your SQL and execute it separately. In my case the problem was in schema definition. I defined the schema, but I should leave it empty. This raised the same exception as you got. And the error description reflected the actual state, as the schema name was included in SQL statement.

Step by steps:

To create/edit the .gemrc file from the terminal:

vi  ~/.gemrc

You will open a editor called vi. paste in:

gem: --no-ri --no-rdoc

click 'esc'-button.

type in:

:exit

You can check if everything is correct with this command:

sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit ~/.gemrc

Assign variable to the blade template, Here are the solutions

We can use <?php ?> tag in blade page

<?php $var = 'test'; ?>
{{ $var }

OR

We can use the blade comment with special syntax

{{--*/ $var = 'test' /*--}}
{{ $var }}

What most of the answers above fail to show is that there is no "One Size Fits All" answer to the original question.

In today's environment we have a large conglomerate of different hardware and software -- some is 32 bit, some is 64 bit, some is cutting edge and some is tried and true - reliable and never changing. Added to that is a variety of older and newer hardware, older and newer OSes, different vendors (Windows, Unixes, Apple, etc.) and a myriad of utilities and servers that go along. As hardware has improved and software is converted to 64 bit compatibility, there has necessarily been considerable delay in getting all the pieces of this very large and complex world to play nicely with the rapid pace of changes.

IMHO there is no one way to fix a problem. The solution is to research the possibilities and then by trial and error find what works best for your particular needs. Each user must determine what works for their system rather than using a cookie cutter approach.

I for example have a media server with a few very large files. The result is only about 400 files filling a 3 TB drive. Only 1% of the inodes are used but 95% of the total space is used. Someone else, with a lot of smaller files may run out of inodes before they come near to filling the space. (On ext4 filesystems as a rule of thumb, 1 inode is used for each file/directory.) While theoretically the total number of files that may be contained within a directory is nearly infinite, practicality determines that the overall usage determine realistic units, not just filesystem capabilities.

I hope that all the different answers above have promoted thought and problem solving rather than presenting an insurmountable barrier to progress.

We know that video ID is 11 chars length and can be preceded by v= or vi= or v/ or vi/ or youtu.be/. So the simplest way to do this:

<?php
$youtube = 'http://youtube.com/v/dQw4w9WgXcQ?feature=youtube_gdata_player
http://youtube.com/vi/dQw4w9WgXcQ?feature=youtube_gdata_player
http://youtube.com/?v=dQw4w9WgXcQ&feature=youtube_gdata_player
http://www.youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player
http://youtube.com/?vi=dQw4w9WgXcQ&feature=youtube_gdata_player
http://youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player
http://youtube.com/watch?vi=dQw4w9WgXcQ&feature=youtube_gdata_player
http://youtu.be/dQw4w9WgXcQ?feature=youtube_gdata_player';

preg_match_all("#(?<=v=|v\/|vi=|vi\/|youtu.be\/)[a-zA-Z0-9_-]{11}#", $youtube, $matches);

var_dump($matches[0]);

And output:

array(8) {
  [0]=>
  string(11) "dQw4w9WgXcQ"
  [1]=>
  string(11) "dQw4w9WgXcQ"
  [2]=>
  string(11) "dQw4w9WgXcQ"
  [3]=>
  string(11) "dQw4w9WgXcQ"
  [4]=>
  string(11) "dQw4w9WgXcQ"
  [5]=>
  string(11) "dQw4w9WgXcQ"
  [6]=>
  string(11) "dQw4w9WgXcQ"
  [7]=>
  string(11) "dQw4w9WgXcQ"
}

My preference is to utilize the inline attribute. This will cause the icon to correctly scale with the size of the button.

    <button mat-button>
      <mat-icon inline=true>local_movies</mat-icon>
      Movies
    </button>

    <!-- Link button -->
    <a mat-flat-button color="accent" routerLink="/create"><mat-icon inline=true>add</mat-icon> Create</a>

I add this to my styles.css to:

• solve the vertical alignment problem of the icon inside the button
• material icon fonts are always a little too small compared to button text

button.mat-button .mat-icon,
a.mat-button .mat-icon,
a.mat-raised-button .mat-icon,
a.mat-flat-button .mat-icon,
a.mat-stroked-button .mat-icon {
  vertical-align: top;
  font-size: 1.25em;
}

You might want to try this approach:

var  str ="{ "name" : "user"}";
var jsonData = JSON.parse(str);     
console.log(jsonData.name)
//Array Object
str ="[{ "name" : "user"},{ "name" : "user2"}]";
jsonData = JSON.parse(str);     
console.log(jsonData[0].name)

To remove bullet points from unordered lists , you can use:

list-style: none;

You can also use:

list-style-type: none;

Either works but the first is a shorter way to get the same result.

After trying to manually uninstall, and then downloading another copy of the VS 2015 community installer for use with the force uninstall command line argument (Original answer by Michael Schuchardt), I was still unable to modify the install directory.

After testing further, I found that Unity (which integrates with Visual Studio as of Unity 5.2) also had to be removed. At this point Visual Studio Uninstaller (link to latest release on Github) can be used for the final removal of remaining any remaining components.

You will now be able to run the Visual Studio Installer and select a directory or, alternatively, run the install from command line using the "/CustomInstallPath ..." argument.

Combining the previous answers provides these solutions:

if (typeof str == 'string' || str instanceof String)

or

Object.prototype.toString.call(str) == '[object String]'

Ran into this issue. I had to add the following to my build.grade:

apply plugin: 'kotlin-android'

You can always roll your own line reader. I have'nt benchmarked this snippet yet, but it correctly splits the incoming stream of chunks into lines without the trailing '\n'

var last = "";

process.stdin.on('data', function(chunk) {
    var lines, i;

    lines = (last+chunk).split("\n");
    for(i = 0; i < lines.length - 1; i++) {
        console.log("line: " + lines[i]);
    }
    last = lines[i];
});

process.stdin.on('end', function() {
    console.log("line: " + last);
});

process.stdin.resume();

I did come up with this when working on a quick log parsing script that needed to accumulate data during the log parsing and I felt that it would nice to try doing this using js and node instead of using perl or bash.

Anyway, I do feel that small nodejs scripts should be self contained and not rely on third party modules so after reading all the answers to this question, each using various modules to handle line parsing, a 13 SLOC native nodejs solution might be of interest .

I reached the point that I set, up to max_iter=1200000 on my LinearSVC classifier, but still the "ConvergenceWarning" was still present. I fix the issue by just setting dual=False and leaving max_iter to its default.

With LogisticRegression(solver='lbfgs') classifier, you should increase max_iter. Mine have reached max_iter=7600 before the "ConvergenceWarning" disappears when training with large dataset's features.

Combining previous answers:

$('input[name="cols"]').filter("[value='Site']").click();

Figure out what version of python3 you have installed:

yum search pip

and then install the best match. Use reqoquery to find name of resulting pip3.e.g

repoquery -l python36u-pip

tells me to use pip3.6 instead of pip3

 protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);

            //foreach (var relationship in modelBuilder.Model.GetEntityTypes().SelectMany(e => e.GetForeignKeys()))
            //    relationship.DeleteBehavior = DeleteBehavior.Restrict;

            modelBuilder.Entity<User>().ToTable("Users");

            modelBuilder.Entity<IdentityRole<string>>().ToTable("Roles");
            modelBuilder.Entity<IdentityUserToken<string>>().ToTable("UserTokens");
            modelBuilder.Entity<IdentityUserClaim<string>>().ToTable("UserClaims");
            modelBuilder.Entity<IdentityUserLogin<string>>().ToTable("UserLogins");
            modelBuilder.Entity<IdentityRoleClaim<string>>().ToTable("RoleClaims");
            modelBuilder.Entity<IdentityUserRole<string>>().ToTable("UserRoles");

        }
    }

In addition to @ImportanceOfBeingErnest's post, I use the following line to add a legend at an absolute position in a plot.

plt.legend(bbox_to_anchor=(1.0,1.0),\
    bbox_transform=plt.gcf().transFigure)

For unknown reasons, bbox_transform=fig.transFigure does not work with me.

If you don't know the order of the min/max values

Date a, b;   // assume these are set to something
Date d;      // the date in question

return a.compareTo(d) * d.compareTo(b) > 0;

If you want the range to be inclusive

return a.compareTo(d) * d.compareTo(b) >= 0;

this is how you can create an array of boolean in TS and initialize it with false:

var array: boolean[] = [false, false, false]

or another approach can be:

var array2: Array<boolean> =[false, false, false] 

you can specify the type after the colon which in this case is boolean array

(This is for posts, not pages - the principle is same. The permalink hook is different by exact use case)

I just had the same issue and created a more convenient way to do that - where you don't have to re-edit your functions.php all the time, or fiddle around with your server settings on each addition (I do not like both).

TLTR

You can add a filter on the actual WP permalink function you need (for me it was post_link, because I needed that page alias in an archive/category list), and dynamically read the referenced ID from the alias post itself.

This is ok, because the post is an alias, so you won't need the content anyways.

First step is to open the alias post and put the ID of the referenced post as content (and nothing else):

Next, open your functions.php and add:

function prefix_filter_post_permalink($url, $post) {
    // if the content of the post to get the permalink for is just a number...
    if (is_numeric($post->post_content)) {
        // instead, return the permalink for the post that has this ID
        return get_the_permalink((int)$post->post_content);
    }
    return $url;
}
add_filter('post_link', 'prefix_filter_post_permalink', 10, 2 );

That's it

Now, each time you need to create an alias post, just put the ID of the referenced post as the content, and you're done.

This will just change the permalink. Title, excerpt and so on will be shown as-is, which is usually desired. More tweaking to your needs is on you, also, the "is it a number" part in the PHP code is far from ideal, but like this for making the point readable.

String s = "test string (67)";

System.out.println(s.substring(s.indexOf("(")+1,s.indexOf(")")));

Windows provides QueryPerformanceCounter() function, and Unix has gettimeofday() Both functions can measure at least 1 micro-second difference.

From XML.com:

Like xsl:if instructions, xsl:when elements can have more elaborate contents between their start- and end-tags—for example, literal result elements, xsl:element elements, or even xsl:if and xsl:choose elements—to add to the result tree. Their test expressions can also use all the tricks and operators that the xsl:if element's test attribute can use, such as and, or, and function calls, to build more complex boolean expressions.
