You can compare two images using functions from PIL.

import Image
import ImageChops

im1 = Image.open("splash.png")
im2 = Image.open("splash2.png")

diff = ImageChops.difference(im2, im1)

The diff object is an image in which every pixel is the result of the subtraction of the color values of that pixel in the second image from the first image. Using the diff image you can do several things. The simplest one is the diff.getbbox() function. It will tell you the minimal rectangle that contains all the changes between your two images.

You can probably implement approximations of the other stuff mentioned here using functions from PIL as well.

Sharing my solution here, based on Chris' answer. Hope it can help others.

I needed to dynamically append child elements into my JSX, but in a simpler way than conditional checks in my return statement. I want to show a loader in the case that the child elements aren't ready yet. Here it is:

export class Settings extends React.PureComponent {
  render() {
    const loading = (<div>I'm Loading</div>);
    let content = [];
    let pushMessages = null;
    let emailMessages = null;

    if (this.props.pushPreferences) {
       pushMessages = (<div>Push Content Here</div>);
    }
    if (this.props.emailPreferences) {
      emailMessages = (<div>Email Content Here</div>);
    }

    // Push the components in the order I want
    if (emailMessages) content.push(emailMessages);
    if (pushMessages) content.push(pushMessages);

    return (
      <div>
        {content.length ? content : loading}
      </div>
    )
}

Now, I do realize I could also just put {pushMessages} and {emailMessages} directly in my return() below, but assuming I had even more conditional content, my return() would just look cluttered.

Just to continue to all the answers that were given here, especially @James Lanes

the size of the integer type can be expressed by this formula:

total range = (2 ^ bit system)

lower limit = -(2 ^ bit system)*0.5 upper limit = ((2 ^ bit system)*0.5) - 1

I've seen this pattern several times:

>>> class Enumeration(object):
        def __init__(self, names):  # or *names, with no .split()
            for number, name in enumerate(names.split()):
                setattr(self, name, number)

>>> foo = Enumeration("bar baz quux")
>>> foo.quux
2

You can also just use class members, though you'll have to supply your own numbering:

>>> class Foo(object):
        bar  = 0
        baz  = 1
        quux = 2

>>> Foo.quux
2

If you're looking for something more robust (sparse values, enum-specific exception, etc.), try this recipe.

In your mysql command line do the following:

mysql> SHOW GLOBAL VARIABLES LIKE '%timestamp%';
+---------------------------------+-------+
| Variable_name                   | Value |
+---------------------------------+-------+
| explicit_defaults_for_timestamp | OFF   |
| log_timestamps                  | UTC   |
+---------------------------------+-------+
2 rows in set (0.01 sec)

mysql> SET GLOBAL explicit_defaults_for_timestamp = 1;
Query OK, 0 rows affected (0.00 sec)

mysql> SHOW GLOBAL VARIABLES LIKE '%timestamp%';
+---------------------------------+-------+
| Variable_name                   | Value |
+---------------------------------+-------+
| explicit_defaults_for_timestamp | ON    |
| log_timestamps                  | UTC   |
+---------------------------------+-------+
2 rows in set (0.00 sec)

A bit late, but using the extend() function lets you call "hasClass()" on any element, e.g.:
var hasClass = $('#divId').hasClass('someClass');

(function($) {
$.extend({
    hasClass: new function(className) {
        var classAttr = $J(this).attr('class');
        if (classAttr != null && classAttr != undefined) {
            var classList = classAttr.split(/\s+/);
            for(var ix = 0, len = classList.length;ix < len;ix++) {
                if (className === classList[ix]) {
                    return true;
                }
            }
        }
        return false;
    }
}); })(jQuery);

In case of multiple type of select and/or if you want to remove already selected items one by one, directly within a dropdown list items, you can use something like:

jQuery("body").on("click", ".result-selected", function() {
    var locID = jQuery(this).attr('class').split('__').pop();
    // I have a class name: class="result-selected locvalue__209"
    var arrayCurrent = jQuery('#searchlocation').val();
    var index = arrayCurrent.indexOf(locID);
    if (index > -1) {
        arrayCurrent.splice(index, 1);
    }
    jQuery('#searchlocation').val(arrayCurrent).trigger('chosen:updated');
});

This is how the if behaves.

if(turnedOn) // This turnedOn should be a boolean or you could have a condition here which would give a boolean result.
{
// It will come here if turnedOn is true (i.e) the condition in the "if" evaluates to true
}
else
{
// It will come here if turnedOn is false (i.e) the condition in the "if" evaluates to false
}

@Eevee: As the browser becomes the home for richer and richer functionality and starts to replace desktop apps, it's just not going to be an option to forgo the use of keyboard shortcuts. Gmail's rich and intuitive set of keyboard commands was instrumental in my willingness to abandon Outlook. The keyboard shortcuts in Todoist, Google Reader, and Google Calendar all make my life much, much easier on a daily basis.

Developers should definitely be careful not to override keystrokes that already have a meaning in the browser. For example, the WMD textbox I'm typing into inexplicably interprets Ctrl+Del as "Blockquote" rather than "delete word forward". I'm curious if there's a standard list somewhere of "browser-safe" shortcuts that site developers can use and that browsers will commit to staying away from in future versions.

Try this link1,link2

@font-face {
        font-family: 'RieslingRegular';
        src: url('fonts/riesling.eot');
        src: local('Riesling Regular'), local('Riesling'), url('fonts/riesling.ttf')                       format('truetype');
    }

I noticed that leowebdev's post did seem to work on my end, however, it did knock out two elements of the site that I am trying to make: the scrolling and the footer.

The scrolling I got back by adding a scrolling="yes" To the iframe embed code.

I am not sure if the footer is automatically knocked out because of the responsiveness or not, but hopefully someone else knows that answer.

So many responses here require coding changes and customized classes and it really is not necessary. Gte a debugging proxy such as fiddler and set your java environment to use the proxy on the command line (-Dhttp.proxyHost and -Dhttp.proxyPort) then run fiddler and you can see the requests and responses in their entirety. Also comes with many ancillary advantages such as the ability to tinker with the results and responses before and after they are sent to run experiments before committing to modification of the server.

Last bit of an issue that can come up is if you must use HTTPS, you will need to export the SSL cert from fiddler and import it into the java keystore (cacerts) hint: default java keystore password is usually "changeit".

For me, this was a permissions issue.

Use the 'Take Ownership' application on that specific folder. However, this sometimes seems to work only temporarily and is not a permanent solution.

For completeness - adding to accepted answer above - in case you are interested in any sibling regardless of the element type you can use variation:

following-sibling::*

Toggle between two classes 'A' and 'B' with Jquery.

$('#selecor_id').toggleClass("A B");

CSS3 allows this sort of thing and it looks like this:

body {
    background-image: url(images/bgtop.png), url(images/bg.png);
    background-repeat: repeat-x, repeat;
}

The current versions of all the major browsers now support it, however if you need to support IE8 or below, then the best way you can work around it is to have extra divs:

<body>
    <div id="bgTopDiv">
        content here
    </div>
</body>

body{
    background-image: url(images/bg.png);
}
#bgTopDiv{
    background-image: url(images/bgTop.png);
    background-repeat: repeat-x;
}

The accept attribute is incredibly useful. It is a hint to browsers to only show files that are allowed for the current input. While it can typically be overridden by users, it helps narrow down the results for users by default, so they can get exactly what they're looking for without having to sift through a hundred different file types.

Usage

Note: These examples were written based on the current specification and may not actually work in all (or any) browsers. The specification may also change in the future, which could break these examples.

h1 { font-size: 1em; margin:1em 0; }_x000D_
h1 ~ h1 { border-top: 1px solid #ccc; padding-top: 1em; }

<h1>Match all image files (image/*)</h1>_x000D_
<p><label>image/* <input type="file" accept="image/*"></label></p>_x000D_
_x000D_
<h1>Match all video files (video/*)</h1>_x000D_
<p><label>video/* <input type="file" accept="video/*"></label></p>_x000D_
_x000D_
<h1>Match all audio files (audio/*)</h1>_x000D_
<p><label>audio/* <input type="file" accept="audio/*"></label></p>_x000D_
_x000D_
<h1>Match all image files (image/*) and files with the extension ".someext"</h1>_x000D_
<p><label>.someext,image/* <input type="file" accept=".someext,image/*"></label></p>_x000D_
_x000D_
<h1>Match all image files (image/*) and video files (video/*)</h1>_x000D_
<p><label>image/*,video/* <input type="file" accept="image/*,video/*"></label></p>

From the HTML Specification (source)

The accept attribute may be specified to provide user agents with a hint of what file types will be accepted.

If specified, the attribute must consist of a set of comma-separated tokens, each of which must be an ASCII case-insensitive match for one of the following:

The string audio/*

• Indicates that sound files are accepted.

The string video/*

• Indicates that video files are accepted.

The string image/*

• Indicates that image files are accepted.

A valid MIME type with no parameters

• Indicates that files of the specified type are accepted.

A string whose first character is a U+002E FULL STOP character (.)

• Indicates that files with the specified file extension are accepted.

Two approaches that come to mind:

          A         B         C         D

Edit: The original answer suggested the use of df.ix[:,2] but this function is now deprecated. Users should switch to df.iloc[:,2].

One can either use del or pop, but I prefer del, since you can specify index and slices, giving the user more control over the data.

For example, starting with the list shown, one can remove its last element with del as a slice, and then one can remove the last element from the result using pop.

>>> l = [1,2,3,4,5]
>>> del l[-1:]
>>> l
[1, 2, 3, 4]
>>> l.pop(-1)
4
>>> l
[1, 2, 3]

You should not map score to player. You should map player (or his name) to score:

Map<Player, Integer> player2score = new HashMap<Player, Integer>();

Then add players to map: int score = .... Player player = new Player(); player.setName("John"); // etc. player2score.put(player, score);

In this case the task is trivial:

int score = player2score.get(player);

If you want to declare an empty array of string type you can do that in 5 different way:-

var myArray: Array<String> = Array()
var myArray = [String]()
var myArray: [String] = []
var myArray = Array<String>()
var myArray:Array<String> = []

Array of any type :-

    var myArray: Array<AnyObject> = Array()
    var myArray = [AnyObject]()
    var myArray: [AnyObject] = []
    var myArray = Array<AnyObject>()
    var myArray:Array<AnyObject> = []

Array of Integer type :-

    var myArray: Array<Int> = Array()
    var myArray = [Int]()
    var myArray: [Int] = []
    var myArray = Array<Int>()
    var myArray:Array<Int> = []

I know its too longtime to reply but just as an information purpose for future readers:

WebRequest

System.Object
    System.MarshalByRefObject
        System.Net.WebRequest

The WebRequest is an abstract base class. So you actually don't use it directly. You use it through it derived classes - HttpWebRequest and FileWebRequest.

You use Create method of WebRequest to create an instance of WebRequest. GetResponseStream returns data stream.

There are also FileWebRequest and FtpWebRequest classes that inherit from WebRequest. Normally, you would use WebRequest to, well, make a request and convert the return to either HttpWebRequest, FileWebRequest or FtpWebRequest, depend on your request. Below is an example:

Example:

var _request = (HttpWebRequest)WebRequest.Create("http://stackverflow.com");
var _response = (HttpWebResponse)_request.GetResponse();

WebClient

System.Object
        System.MarshalByRefObject
            System.ComponentModel.Component
                System.Net.WebClient

WebClient provides common operations to sending and receiving data from a resource identified by a URI. Simply, it’s a higher-level abstraction of HttpWebRequest. This ‘common operations’ is what differentiate WebClient from HttpWebRequest, as also shown in the sample below:

Example:

var _client = new WebClient();
var _stackContent = _client.DownloadString("http://stackverflow.com");

There are also DownloadData and DownloadFile operations under WebClient instance. These common operations also simplify code of what we would normally do with HttpWebRequest. Using HttpWebRequest, we have to get the response of our request, instantiate StreamReader to read the response and finally, convert the result to whatever type we expect. With WebClient, we just simply call DownloadData, DownloadFile or DownloadString.

However, keep in mind that WebClient.DownloadString doesn’t consider the encoding of the resource you requesting. So, you would probably end up receiving weird characters if you don’t specify and encoding.

NOTE: Basically "WebClient takes few lines of code as compared to Webrequest"

I used the sdk.

eg:

using SevenZip.Compression.LZMA;
private static void CompressFileLZMA(string inFile, string outFile)
{
   SevenZip.Compression.LZMA.Encoder coder = new SevenZip.Compression.LZMA.Encoder();

   using (FileStream input = new FileStream(inFile, FileMode.Open))
   {
      using (FileStream output = new FileStream(outFile, FileMode.Create))
      {
          coder.Code(input, output, -1, -1, null);
          output.Flush();
      }
   }
}

Use FormData object.It works for any type of form

$(document).on("submit", "form", function(event)
{
    event.preventDefault();
    $.ajax({
        url: $(this).attr("action"),
        type: $(this).attr("method"),
        dataType: "JSON",
        data: new FormData(this),
        processData: false,
        contentType: false,
        success: function (data, status)
        {

        },
        error: function (xhr, desc, err)
        {
            

        }
    });        

});

Do git help gitignore

You will get the help page with following line:

A line starting with # serves as a comment.

If you're coming here wondering the opposite (as I was), this post may be for you.

I couldn't figure out why my notifications were clearing when I cleared the badge...I manually increment the badge and then want to clear it when the user enters the app. That's no reason to clear out the notification center, though; they may still want to see or act on those notifications.

Negative 1 does the trick, luckily:

[UIApplication sharedApplication].applicationIconBadgeNumber = -1;

After a long research I build this reg expression. I hope it will help others too.......

url = 'https://google.co.in';
var re = /[a-z0-9-\.]+\.[a-z]{2,4}\/?([^\s<>\#%"\,\{\}\\|\\\^\[\]`]+)?$/;
if (!re.test(url)) { 
 alert("url error");
return false;
}else{
alert('success')
}

The answer for Swift 2.0 Alamofire 3.0 should actually look more like this:

Alamofire.request(.POST, url, parameters: parameters, encoding:.JSON).responseJSON
{ response in switch response.result {
                case .Success(let JSON):
                    print("Success with JSON: \(JSON)")

                    let response = JSON as! NSDictionary

                    //example if there is an id
                    let userId = response.objectForKey("id")!

                case .Failure(let error):
                    print("Request failed with error: \(error)")
                }
    }

https://github.com/Alamofire/Alamofire/blob/master/Documentation/Alamofire%203.0%20Migration%20Guide.md

UPDATE for Alamofire 4.0 and Swift 3.0 :

Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default)
            .responseJSON { response in
                print(response)
//to get status code
                if let status = response.response?.statusCode {
                    switch(status){
                    case 201:
                        print("example success")
                    default:
                        print("error with response status: \(status)")
                    }
                }
//to get JSON return value
            if let result = response.result.value {
                let JSON = result as! NSDictionary
                print(JSON)
            }

        }

For this specific problem, something like this would work:

$ sed 's/^ *//g' < input.txt > output.txt

It says to replace all spaces at the start of a line with nothing. If you also want to remove tabs, change it to this:

$ sed 's/^[ \t]+//g' < input.txt > output.txt

The leading "s" before the / means "substitute". The /'s are the delimiters for the patterns. The data between the first two /'s are the pattern to match, and the data between the second and third / is the data to replace it with. In this case you're replacing it with nothing. The "g" after the final slash means to do it "globally", ie: over the entire file rather than on only the first match it finds.

Finally, instead of < input.txt > output.txt you can use the -i option which means to edit the file "in place". Meaning, you don't need to create a second file to contain your result. If you use this option you will lose your original file.

Some times less is more, do you really need to know the percentage through the file you are when coding? What about the type of file?

set statusline=%F%m%r%h%w\ 
set statusline+=%{fugitive#statusline()}\    
set statusline+=[%{strlen(&fenc)?&fenc:&enc}]
set statusline+=\ [line\ %l\/%L]          
set statusline+=%{rvm#statusline()}       

I also prefer minimal color as not to distract from the code.

Taken from: https://github.com/krisleech/vimfiles

Note: rvm#statusline is Ruby specific and fugitive#statusline is git specific.

I'm using the first approach but a bit different that allows to address the problems you mentioned.

Everything that is needed to run tests for DAOs is in source control. It includes schema and scripts to create the DB (docker is very good for this). If the embedded DB can be used - I use it for speed.

The important difference with the other described approaches is that the data that is required for test is not loaded from SQL scripts or XML files. Everything (except some dictionary data that is effectively constant) is created by application using utility functions/classes.

The main purpose is to make data used by test

1. very close to the test
2. explicit (using SQL files for data make it very problematic to see what piece of data is used by what test)
3. isolate tests from the unrelated changes.

It basically means that these utilities allow to declaratively specify only things essential for the test in test itself and omit irrelevant things.

To give some idea of what it means in practice, consider the test for some DAO which works with Comments to Posts written by Authors. In order to test CRUD operations for such DAO some data should be created in the DB. The test would look like:

@Test
public void savedCommentCanBeRead() {
    // Builder is needed to declaratively specify the entity with all attributes relevant
    // for this specific test
    // Missing attributes are generated with reasonable values
    // factory's responsibility is to create entity (and all entities required by it
    //  in our example Author) in the DB
    Post post = factory.create(PostBuilder.post());

    Comment comment = CommentBuilder.comment().forPost(post).build();

    sut.save(comment);

    Comment savedComment = sut.get(comment.getId());

    // this checks fields that are directly stored
    assertThat(saveComment, fieldwiseEqualTo(comment));
    // if there are some fields that are generated during save check them separately
    assertThat(saveComment.getGeneratedField(), equalTo(expectedValue));        
}

This has several advantages over SQL scripts or XML files with test data:

1. Maintaining the code is much easier (adding a mandatory column for example in some entity that is referenced in many tests, like Author, does not require to change lots of files/records but only a change in builder and/or factory)
2. The data required by specific test is described in the test itself and not in some other file. This proximity is very important for test comprehensibility.

Rollback vs Commit

I find it more convenient that tests do commit when they are executed. Firstly, some effects (for example DEFERRED CONSTRAINTS) cannot be checked if commit never happens. Secondly, when a test fails the data can be examined in the DB as it is not reverted by the rollback.

Of cause this has a downside that test may produce a broken data and this will lead to the failures in other tests. To deal with this I try to isolate the tests. In the example above every test may create new Author and all other entities are created related to it so collisions are rare. To deal with the remaining invariants that can be potentially broken but cannot be expressed as a DB level constraint I use some programmatic checks for erroneous conditions that may be run after every single test (and they are run in CI but usually switched off locally for performance reasons).

You can use the DataRowView to get the column index.

    void OnRequestsGridRowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            var data = e.Row.DataItem as DataRowView;

            // replace request name with a link
            if (data.DataView.Table.Columns["Request Name"] != null)
            {
                // get the request name
                string title = data["Request Name"].ToString();
                // get the column index
                int idx = data.Row.Table.Columns["Request Name"].Ordinal;

                // ...

                e.Row.Cells[idx].Controls.Clear();
                e.Row.Cells[idx].Controls.Add(link);
            }
        }
    }

If you only want to commit all the changes in one commit as if you typed yourself, --squash will do too

$ git merge --squash v1.0
$ git commit

You can also use batch functions for this:

@echo off
setlocal 

goto MAIN
::-----------------------------------------------
:: "%~f2" get abs path of %~2. 
::"%~fs2" get abs path with short names of %~2.
:setAbsPath
  setlocal
  set __absPath=%~f2
  endlocal && set %1=%__absPath%
  goto :eof
::-----------------------------------------------

:MAIN
call :setAbsPath ABS_PATH ..\
echo %ABS_PATH%

endlocal

You can escape shell metacharacters with ^:

echo ^<?xml version="1.0" encoding="utf-8" ?^> > myfile.xml

Note that since echo is a shell built-in it doesn't follow the usual conventions regarding quoting, so just quoting the argument will output the quotes instead of removing them.

If none of the above works, try using this in web.config or app.config:

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30AD4FE6B2A6AEED" culture="neutral"/>
            <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0"/>
        </dependentAssembly>
    </assemblyBinding>
</runtime>

You mention you are using Pandas (in your title). If so, there is no need to use an external library, you can just use to_datetime

>>> pandas.to_datetime('today').normalize()
Timestamp('2015-10-14 00:00:00')

This will always return today's date at midnight, irrespective of the actual time, and can be directly used in pandas to do comparisons etc. Pandas always includes 00:00:00 in its datetimes.

Replacing today with now would give you the date in UTC instead of local time; note that in neither case is the tzinfo (timezone) added.

In pandas versions prior to 0.23.x, normalize may not have been necessary to remove the non-midnight timestamp.

You are doing it right, so I guess something else is at fault (not export-ing COLUMNS ?).

A trick to debug these cases is to make a specialized command (a closure for programming language guys). Create a shell script named diff-columns doing:

exec /usr/bin/diff -x -y -w -p -W "$COLUMNS" "$@"

and just use

svn diff "$@" --diff-cmd  diff-columns

This way your code is cleaner to read and more modular (top-down approach), and you can test the diff-columns code thouroughly separately (bottom-up approach).

Update: Using DateTimeFormat, introduced in java 8:

The idea is to define two formats: one for the input format, and one for the output format. Parse with the input formatter, then format with the output formatter.

Your input format looks quite standard, except the trailing Z. Anyway, let's deal with this: "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'". The trailing 'Z' is the interesting part. Usually there's time zone data here, like -0700. So the pattern would be ...Z, i.e. without apostrophes.

The output format is way more simple: "dd-MM-yyyy". Mind the small y -s.

Here is the example code:

DateTimeFormatter inputFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
DateTimeFormatter outputFormatter = DateTimeFormatter.ofPattern("dd-MM-yyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse("2018-04-10T04:00:00.000Z", inputFormatter);
String formattedDate = outputFormatter.format(date);
System.out.println(formattedDate); // prints 10-04-2018

Original answer - with old API SimpleDateFormat

SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
SimpleDateFormat outputFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = inputFormat.parse("2018-04-10T04:00:00.000Z");
String formattedDate = outputFormat.format(date);
System.out.println(formattedDate); // prints 10-04-2018

I have built a complete javascript solution as well that does not require jquery. Might be able to turn it into a plugin. I use it for fluid auto-refreshing, but it looks like it could help you here.

JSFiddle AutoRefresh

// Refresh Rate is how often you want to refresh the page 
// bassed off the user inactivity. 
var refresh_rate = 200; //<-- In seconds, change to your needs
var last_user_action = 0;
var has_focus = false;
var lost_focus_count = 0;
// If the user loses focus on the browser to many times 
// we want to refresh anyway even if they are typing. 
// This is so we don't get the browser locked into 
// a state where the refresh never happens.    
var focus_margin = 10; 

// Reset the Timer on users last action
function reset() {
    last_user_action = 0;
    console.log("Reset");
}

function windowHasFocus() {
    has_focus = true;
}

function windowLostFocus() {
    has_focus = false;
    lost_focus_count++;
    console.log(lost_focus_count + " <~ Lost Focus");
}

// Count Down that executes ever second
setInterval(function () {
    last_user_action++;
    refreshCheck();
}, 1000);

// The code that checks if the window needs to reload
function refreshCheck() {
    var focus = window.onfocus;
    if ((last_user_action >= refresh_rate && !has_focus && document.readyState == "complete") || lost_focus_count > focus_margin) {
        window.location.reload(); // If this is called no reset is needed
        reset(); // We want to reset just to make sure the location reload is not called.
    }

}
window.addEventListener("focus", windowHasFocus, false);
window.addEventListener("blur", windowLostFocus, false);
window.addEventListener("click", reset, false);
window.addEventListener("mousemove", reset, false);
window.addEventListener("keypress", reset, false);
window.addEventListener("scroll", reset, false);
document.addEventListener("touchMove", reset, false);
document.addEventListener("touchEnd", reset, false);

First of all, %d is for a int

So %1.16lld makes no sense, because %d is an integer

That typedef you do, is also unnecessary, use the type straight ahead, makes a much more readable code.

What you want to use is the type double, for calculating pi and then using %f or %1.16f.

Calculate the difference between two dates include fraction of month (days).

var difference = (date2.getDate() - date1.getDate()) / 30 +
    date2.getMonth() - date1.getMonth() +
    (12 * (date2.getFullYear() - date1.getFullYear()));

For example:
date1: 24/09/2015 (24th Sept 2015)
date2: 09/11/2015 (9th Nov 2015)
the difference: 2.5 (months)

Fixing the sample data so it matches the original description 'each item is a list of length 20'

mylistlist <- replicate(
  132,
  as.list(sample(letters, 20)),
  simplify = FALSE
)

we can convert it to a data frame like this:

data.frame(t(sapply(mylistlist,c)))

sapply converts it to a matrix. data.frame converts the matrix to a data frame.

resulting in:

The %in% operator tells you which elements are among the numers to remove:

> a <- sample (1 : 10)
> remove <- c (2, 3, 5)
> a
 [1] 10  5  2  7  1  6  3  4  8  9
> a %in% remove
 [1] FALSE  TRUE  TRUE FALSE FALSE FALSE  TRUE FALSE FALSE FALSE
> a [! a %in% remove]
 [1] 10  7  1  6  4  8  9

Note that this will silently remove incomparables (stuff like NA or Inf) as well (while it will keep duplicate values in a as long as they are not listed in remove).

• If a can contain incomparables, but remove will not, we can use match, telling it to return 0 for non-matches and incomparables (%in% is a conventient shortcut for match):

  > a <- c (a, NA, Inf)
  > a
   [1]  10   5   2   7   1   6   3   4   8   9  NA Inf
  > match (a, remove, nomatch = 0L, incomparables = 0L)
   [1] 0 3 1 0 0 0 2 0 0 0 0 0
  > a [match (a, remove, nomatch = 0L, incomparables = 0L) == 0L]
  [1]  10   7   1   6   4   8   9  NA Inf
  

  incomparables = 0 is not needed as incomparables will anyways not match, but I'd include it for the sake of readability.
  This is, btw., what setdiff does internally (but without the unique to throw away duplicates in a which are not in remove).

• If remove contains incomparables, you'll have to check for them individually, e.g.

  if (any (is.na (remove))) 
    a <- a [! is.na (a)]
  

  (This does not distinguish NA from NaN but the R manual anyways warns that one should not rely on having a difference between them)

  For Inf/ -Inf you'll have to check both sign and is.finite

NSDictionary from NSData

http://www.cocoanetics.com/2009/09/nsdictionary-from-nsdata/

NSDictionary to NSData

You can use NSPropertyListSerialization class for that. Have a look at its method:

+ (NSData *)dataFromPropertyList:(id)plist format:(NSPropertyListFormat)format
                              errorDescription:(NSString **)errorString

Returns an NSData object containing a given property list in a specified format.

I try to write working code example, I test it and everything works.

Hare is code:

HTML:

<input type="file" class="attachment_input" name="file" onchange="checkFileSize(this, @Model.MaxSize.ToString(),@Html.Raw(Json.Encode(Model.FileExtensionsList)))" />

Javascript:

 //function for check attachment size and extention match
function checkFileSize(element, maxSize, extentionsArray) {
    var val = $(element).val(); //get file value

    var ext = val.substring(val.lastIndexOf('.') + 1).toLowerCase(); // get file extention 
    if ($.inArray(ext, extentionsArray) == -1) {
        alert('false extension!');
    }

    var fileSize = ($(element)[0].files[0].size / 1024 / 1024); //size in MB
    if (fileSize > maxSize) {
        alert("Large file");// if Maxsize from Model > real file size alert this
    }
}

swift

func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool {
    if text == "\n" {
        textView.resignFirstResponder()
    }
    return true
}

This can be because of following reason:

1. one of the jar files inside project was using an older version of google play services.

2. use multiDexEnabled true in defaultconfig

3. Be specific with classes you add in dependencies. like

   compile 'com.google.android.gms:play-services-maps:8.4.0'

Not like compile 'com.google.android.gms:play-services:+'

For Swift 4.2 and above

let supportEmail = "[email protected]"
if let emailURL = URL(string: "mailto:\(supportEmail)"), UIApplication.shared.canOpenURL(emailURL)
{
    UIApplication.shared.open(emailURL, options: [:], completionHandler: nil)
}

Give the user to choose many mail options(like iCloud, google, yahoo, Outlook.com - if no mail is pre-configured in his phone) to send email.

hive stores only the meta data in metastore and original data in out side of hive when we use external table we can give location' ' by these our original data wont effect when we drop the table

You can also query the INFORMATION_SCHEMA.SCHEMATA view:

SELECT SCHEMA_NAME FROM INFORMATION_SCHEMA.SCHEMATA

I believe querying the INFORMATION_SCHEMA views is recommended as they protect you from changes to the underlying sys tables. From the SQL Server 2008 R2 Help:

Information schema views provide an internal, system table-independent view of the SQL Server metadata. Information schema views enable applications to work correctly although significant changes have been made to the underlying system tables. The information schema views included in SQL Server comply with the ISO standard definition for the INFORMATION_SCHEMA.

Ironically, this is immediately preceded by this note:

Some changes have been made to the information schema views that break backward compatibility. These changes are described in the topics for the specific views.

This work for me for a location in India:

SET GLOBAL time_zone = "Asia/Calcutta";
SET time_zone = "+05:30";
SET @@session.time_zone = "+05:30";

A lot of the above work. Just to add. If your textboxes are not directly on the form but are on other container objects like a GroupBox, you will have to get the GroupBox object and then iterate through the GroupBox to access the textboxes contained therein.

foreach(Control t in this.Controls.OfType<GroupBox>())
{
   foreach (Control tt in t.Controls.OfType<TextBox>())
   {
        // do stuff
   }
}

In addition to Mark's answer, you also need to be aware of scope, which (as in C/C++) is specified using braces. So:

if (textBox1.Text == "" || textBox1.Text == String.Empty || textBox1.TextLength == 0)
    textBox3.Text += "[-] Listbox is Empty!!!!\r\n";
return;

will always return at that point. However:

if (textBox1.Text == "" || textBox1.Text == String.Empty || textBox1.TextLength == 0)
{
    textBox3.Text += "[-] Listbox is Empty!!!!\r\n";
    return;
}

will only return if it goes into that if statement.

Here is a very good way to handle this (found on ozgrid):

Let's say your list is on Sheet2 and you wish to use the Validation List with AutoComplete on Sheet1.

On Sheet1 A1 Enter =Sheet2!A1 and copy down including as many spare rows as needed (say 300 rows total). Hide these rows and use this formula in the Refers to: for a dynamic named range called MyList:

=OFFSET(Sheet1!$A$1,0,0,MATCH("*",Sheet1!$A$1:$A$300,-1),1)

Now in the cell immediately below the last hidden row use Data Validation and for the List Source use =MyList

[EDIT] Adapted version for Excel 2007+ (couldn't test on 2010 though but AFAIK, there is nothing really specific to a version).
Let's say your data source is on Sheet2!A1:A300 and let's assume your validation list (aka autocomplete) is on cell Sheet1!A1.

1. Create a dynamic named range MyList that will depend on the value of the cell where you put the validation

   =OFFSET(Sheet2!$A$1,MATCH(Sheet1!$A$1&"*",Sheet2!$A$1:$A$300,0)-1,0,COUNTA(Sheet2!$A:$A))

2. Add the validation list on cell Sheet1!A1 that will refert to the list =MyList

Caveats

1. This is not a real autocomplete as you have to type first and then click on the validation arrow : the list will then begin at the first matching element of your list

2. The list will go till the end of your data. If you want to be more precise (keep in the list only the matching elements), you can change the COUNTA with a SUMLPRODUCT that will calculate the number of matching elements

3. Your source list must be sorted

Constructors are not normal methods and they cannot be "overridden". Saying that a constructor can be overridden would imply that a superclass constructor would be visible and could be called to create an instance of a subclass. This isn't true... a subclass doesn't have any constructors by default (except a no-arg constructor if the class it extends has one). It has to explicitly declare any other constructors, and those constructors belong to it and not to its superclass, even if they take the same parameters that the superclass constructors take.

The stuff you mention about default no arg constructors is just an aspect of how constructors work and has nothing to do with overriding.

I used this a little example and it worked.

$('#date').datetimepicker({
    defaultDate: new Date()
});

demo : http://jsfiddle.net/m2fjw57b/1/

Works fine too:

/* small screen portrait */

@media (max-width: 321px) {

  .pull-right { 
    float: none!important; 
  }

}


/* small screen lanscape */

@media (max-width: 480px) {

  .pull-right {
    float: none!important; 
  }

}

I tried lashrah's answer and it worked after changing syntax a little bit. this is what worked for me:

@(
  ((HomeController)this.ViewContext.Controller).Method1();
)

Here's a simple circle_background.xml for pre-material:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape android:shape="oval">
            <solid android:color="@color/color_accent_dark" />
        </shape>
    </item>
    <item>
        <shape android:shape="oval">
            <solid android:color="@color/color_accent" />
        </shape>
    </item>
</selector>

You can use with the attribute 'android:background="@drawable/circle_background" in your button's layout definition

CONCAT_WS still produces null for me if the first field is Null. I solved this by adding a zero length string at the beginning as in

CONCAT_WS("",`affiliate_name`,'-',`model`,'-',`ip`,'-',`os_type`,'-',`os_version`)

however

CONCAT("",`affiliate_name`,'-',`model`,'-',`ip`,'-',`os_type`,'-',`os_version`) 

produces Null when the first field is Null.

If you mean the type of procedure you find in SQL Server, prior to 2010, you can't. If you want a query that accepts a parameter, you can use the query design window:

 PARAMETERS SomeParam Text(10);
 SELECT Field FROM Table
 WHERE OtherField=SomeParam

You can also say:

CREATE PROCEDURE ProcedureName
   (Parameter1 datatype, Parameter2 datatype) AS
   SQLStatement

From: http://msdn.microsoft.com/en-us/library/aa139977(office.10).aspx#acadvsql_procs

Note that the procedure contains only one statement.

What you can do is set specific width and height to your iframe (for example these could be equal to your window dimensions) and then applying a scale transformation to it. The scale value will be the ratio between your window width and the dimension you wanted to set to your iframe.

E.g.

<iframe width="1024" height="768" src="http://www.bbc.com" style="-webkit-transform:scale(0.5);-moz-transform-scale(0.5);"></iframe>

A simple way to getting resource string from string into a TextView. Here resourceName is the name of resource

int resID = getResources().getIdentifier(resourceName, "string", getPackageName());
textview.setText(resID);

I don't know why but for me the solution proposed by Marius Stanescu is breaking the specificity of col (a col-md-3 followed by a col-md-4 will take all of the twelve row)

I found another working solution :

.bottom-column 
{
   display: inline-block;
   vertical-align: middle;
   float: none;
}

I have always wanted Visual Studio to include an option to just collapse / expand the regions. I have the following macros which will do just that.

Imports EnvDTE
Imports System.Diagnostics
' Macros for improving keyboard support for "#region ... #endregion"
Public Module CollapseExpandRegions
' Expands all regions in the current document
  Sub ExpandAllRegions()

    Dim objSelection As TextSelection ' Our selection object

    DTE.SuppressUI = True ' Disable UI while we do this
    objSelection = DTE.ActiveDocument.Selection() ' Hook up to the ActiveDocument's selection
    objSelection.StartOfDocument() ' Shoot to the start of the document

    ' Loop through the document finding all instances of #region. This action has the side benefit
    ' of actually zooming us to the text in question when it is found and ALSO expanding it since it
    ' is an outline.
    Do While objSelection.FindText("#region", vsFindOptions.vsFindOptionsMatchInHiddenText)
        ' This next command would be what we would normally do *IF* the find operation didn't do it for us.
        'DTE.ExecuteCommand("Edit.ToggleOutliningExpansion")
    Loop
    objSelection.StartOfDocument() ' Shoot us back to the start of the document
    DTE.SuppressUI = False ' Reenable the UI

    objSelection = Nothing ' Release our object

  End Sub

  ' Collapses all regions in the current document
  Sub CollapseAllRegions()
    Dim objSelection As TextSelection ' Our selection object

    ExpandAllRegions() ' Force the expansion of all regions

    DTE.SuppressUI = True ' Disable UI while we do this
    objSelection = DTE.ActiveDocument.Selection() ' Hook up to the ActiveDocument's selection
    objSelection.EndOfDocument() ' Shoot to the end of the document

    ' Find the first occurence of #region from the end of the document to the start of the document. Note:
    ' Note: Once a #region is "collapsed" .FindText only sees it's "textual descriptor" unless
    ' vsFindOptions.vsFindOptionsMatchInHiddenText is specified. So when a #region "My Class" is collapsed,
    ' .FindText would subsequently see the text 'My Class' instead of '#region "My Class"' for the subsequent
    ' passes and skip any regions already collapsed.
    Do While (objSelection.FindText("#region", vsFindOptions.vsFindOptionsBackwards))
        DTE.ExecuteCommand("Edit.ToggleOutliningExpansion") ' Collapse this #region
        'objSelection.EndOfDocument() ' Shoot back to the end of the document for
        ' another pass.
    Loop
    objSelection.StartOfDocument() ' All done, head back to the start of the doc
    DTE.SuppressUI = False ' Reenable the UI

    objSelection = Nothing ' Release our object

  End Sub
End Module

EDIT: There is now a shortcut called Edit.ToggleOutliningExpansion (Ctrl+M, Ctrl+M) for doing just that.

You can use the root.configure(background='your colour') example:- import tkinter root=tkiner.Tk() root.configure(background='pink')

Try figsize param in df.plot(figsize=(width,height)):

df = pd.DataFrame({"a":[1,2],"b":[1,2]})
df.plot(figsize=(3,3));

df = pd.DataFrame({"a":[1,2],"b":[1,2]})
df.plot(figsize=(5,3));

The size in figsize=(5,3) is given in inches per (width, height)

Just use . for concatenating. And you missed out the $personCount increment!

while ($personCount < 10) {
    $result .= $personCount . ' people';
    $personCount++;
}

echo $result;

You can' just add a class to each of your DIVs and apply the rule to the class in this way:

HTML:

<div class="myclass" id="s1">...</div>
<div class="myclass" id="s2">...</div>

CSS:

//css
.myclass
{
   ...
}

This is one way to adding constraints programmatically

override func viewDidLoad() {
            super.viewDidLoad()


let myLabel = UILabel()
        myLabel.labelFrameUpdate(label: myLabel, text: "Welcome User", font: UIFont(name: "times new roman", size: 40)!, textColor: UIColor.red, textAlignment: .center, numberOfLines: 0, borderWidth: 2.0, BorderColor: UIColor.red.cgColor)
        self.view.addSubview(myLabel)


         let myLabelhorizontalConstraint = NSLayoutConstraint(item: myLabel, attribute: NSLayoutAttribute.centerX, relatedBy: NSLayoutRelation.equal, toItem: self.view, attribute: NSLayoutAttribute.centerX, multiplier: 1, constant: 0)
        let myLabelverticalConstraint = NSLayoutConstraint(item: myLabel, attribute: NSLayoutAttribute.centerY, relatedBy: NSLayoutRelation.equal, toItem: self.view, attribute: NSLayoutAttribute.centerY, multiplier: 1, constant: 0)
        let mylabelLeading = NSLayoutConstraint(item: myLabel, attribute: NSLayoutAttribute.leading, relatedBy: NSLayoutRelation.equal, toItem: self.view, attribute: NSLayoutAttribute.leading, multiplier: 1, constant: 10)

You mention batch files, am I correct then assuming that you're talking about a Windows system? If so you cannot use sshpass, and you will have to switch to a different option.

Two of such options, that follow diametrically opposite philosophies are:

• psftp: command-line tool that you can call from within your batch scripts; psftp is part of the PuTTY package and you can find it here http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
• Syncplify.me FTP Script: a scriptable FTP/S and SFTP client for Windows that allows you to store your password in encrypted "profile files"; check it out here http://www.syncplify.me/products/ftp-script/

Either way, switching from password to PKI authentication is strongly recommended.

A combination of previous 2 answers did the trick. Thanks. A new class which inherits from Button. Note: updateImages() should be called before showing the button.

import javafx.event.EventHandler;
import javafx.scene.control.Button;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.input.MouseEvent;

public class ImageButton extends Button {

    public void updateImages(final Image selected, final Image unselected) {
        final ImageView iv = new ImageView(selected);
        this.getChildren().add(iv);

        iv.setOnMousePressed(new EventHandler<MouseEvent>() {
            public void handle(MouseEvent evt) {
                iv.setImage(unselected);
            }
        });
        iv.setOnMouseReleased(new EventHandler<MouseEvent>() {
            public void handle(MouseEvent evt) {
                iv.setImage(selected);
            }
        });

        super.setGraphic(iv);
    }
}

The RecyclerView takes care of adding, removing, and re-ordering animations!

This simple AndroidStudio project features a RecyclerView. take a look at the commits:

1. commit of the classic Hello World Android app
2. commit, adding a RecyclerView to the project (content not dynamic)
3. commit, adding functionality to modify content of RecyclerView at runtime (but no animations)
4. and finally...commit adding animations to the RecyclerView

To store password in database, make hash of password and then save.

$password = Input::get('password_from_user'); 
$hashed = Hash::make($password); // save $hashed value

To verify password, get password stored of account from database

// $user is database object
// $inputs is Input from user
if( \Illuminate\Support\Facades\Hash::check( $inputs['password'], $user['password']) == false) {
  // Password is not matching 
} else {
  // Password is matching 
}

infinite slider adapter skeleton based on previous samples

some critical issues:

• remember original (relative) position in page view (tag used in sample), so we will look this position to define relative position of view. otherwise child order in pager is mixed
• have to fill first time absolute view inside adapter. (the rest of times this fill will be invalid) found no way to force it fill from pager handler. the rest times absolute view will be overriden from pager handler with correct values.
• when pages are slided quickly, side page (actually left) is not filled from pager handler. no workaround for the moment, just use empty view, it will be filled with actual values when drag is stopped. upd: quick workaround: disable adapter's destroyItem.

you may look at the logcat to understand whats happening in this sample

        CalendarAdapter calendarAdapter = this.new CalendarAdapter();
        viewPager.setAdapter(calendarAdapter);

        // center item
        viewPager.setCurrentItem(1, false);
    }
}

For this one, who does not control the server side and because of this is using hash router v2:

Place your history into separate file (e.g. app_history.js ES6):

import { useRouterHistory } from 'react-router'
import { createHashHistory } from 'history'
const appHistory = useRouterHistory(createHashHistory)({ queryKey: false });

export default appHistory;

And use it everywhere!

Your entry point for react-router (app.js ES6):

import React from 'react'
import { render } from 'react-dom'
import { Router, Route, Redirect } from 'react-router'
import appHistory from './app_history'
...
const render((
  <Router history={appHistory}>
  ...
  </Router>
), document.querySelector('[data-role="app"]'));

Your navigation inside any component (ES6):

import appHistory from '../app_history'
...
ajaxLogin('/login', (err, data) => {
  if (err) {
    console.error(err); // login failed
  } else {
    // logged in
    appHistory.replace('/dashboard'); // or .push() if you don't need .replace()
  }
})

Identifying the column is easy:

SELECT  *
FROM    ( SELECT    id,
                    time
          FROM      dbo.a
          UNION
          SELECT    id,
                    time
          FROM      dbo.b
        )
GROUP BY id

But it doesn't solve the main problem of this query: what's to be done with the second column values upon grouping by the first? Since (peculiarly!) you're using UNION rather than UNION ALL, you won't have entirely duplicated rows between the two subtables in the union, but you may still very well have several values of time for one value of the id, and you give no hint of what you want to do - min, max, avg, sum, or what?! The SQL engine should give an error because of that (though some such as mysql just pick a random-ish value out of the several, I believe sql-server is better than that).

So, for example, change the first line to SELECT id, MAX(time) or the like!

Also remember that all info(), error(), and debug() logging calls provide internal documentation within any application.

//for dynamic elements - if you want it in ng-repeat do below code

angular.forEach($scope.data, function(value, key) {
     //add new value to object
    value.new_url  = "your url";
});

 <div ng-repeat="row in data"><a ng-href="{{ row.url_content }}"></a></div>

Well, despite of this entry being very old. I was using bootstrap's modal this week and came along this "issue". My solution was somehow a mix of everything, just posting it as it may help someone :)

First check the Z-index war to get a fix there!

The first thing you can do is deactivate the modal backdrop, I had the Stackoverflow post before but I lost it, so I wont take the credit for it, keep that in mind; but it goes like this in the HTML code:

<!-- from the bootstrap's docs -->_x000D_
<div class="modal fade" tabindex="-1" role="dialog" data-backdrop="false">_x000D_
  <!-- mind the data-backdrop="false" -->_x000D_
  <div class="modal-dialog" role="document">_x000D_
    <!-- ... modal content -->_x000D_
  </div>_x000D_
</div>

The second approach was to have an event listener attached to the bootstrap's shown modal event. This is somehow not so pretty as you may think but maybe with some tricks by your own may somehow work. The advantage of this is that the element attaches the event listener and you can completely forget about it as long as you have the event listener attached :)

var element = $('selector-to-your-modal');_x000D_
_x000D_
// also taken from bootstrap 3 docs_x000D_
$(element).on('shown.bs.modal', function(e) {_x000D_
  // keep in mind this only works as long as Bootstrap only supports 1 modal at a time, which is the case in Bootstrap 3 so far..._x000D_
  var backDrop = $('.modal-backdrop');_x000D_
  $(element).append($(backDrop));_x000D_
});

The second.1 approach is basically the same than the previous but without the event listener.

Hope it helps someone!

you can use ->addOrderBy($sort, $order)

Add:Doctrine Querybuilder btw. often uses "special" modifications of the normal methods, see select-addSelect, where-andWhere-orWhere, groupBy-addgroupBy...

In Visual Studio, you can't just open a .cpp file and expect it to run. You must create a project first, or open the .cpp in some existing project.

In your case, there is no project, so there is no project to build.

Go to File --> New --> Project --> Visual C++ --> Win32 Console Application. You can uncheck "create a directory for solution". On the next page, be sure to check "Empty project".

Then, You can add .cpp files you created outside the Visual Studio by right clicking in the Solution explorer on folder icon "Source" and Add->Existing Item.

Obviously You can create new .cpp this way too (Add --> New). The .cpp file will be created in your project directory.

Then you can press ctrl+F5 to compile without debugging and can see output on console window.

If your textView is allowed to grow as tall as the content, then

textView.isScrollEnabled = false

should just work with autolayout.

If you want to remain the textView to be scrollable, you need to add an optional height constraint,

internal lazy var textViewHeightConstraint: NSLayoutConstraint = {
  let constraint = self.textView.heightAnchor.constraint(equalToConstant: 0)
  constraint.priority = .defaultHigh
  return constraint
}()

public override func layoutSubviews() {
  super.layoutSubviews()

  // Assuming there is width constraint setup on the textView.
  let targetSize = CGSize(width: textView.frame.width, height: CGFloat(MAXFLOAT))
  textViewHeightConstraint.constant = textView.sizeThatFits(targetSize).height
}

The reason to override layoutSubviews() is to make sure the textView is laid out properly horizontally so we can rely on the width to calculate the height.

Since the height constraint is set to a lower priority, if it runs out space vertically the actual height of the textView will be less than the contentSize. And the textView will be scrollable.

You can use \n to concatenate words and then apply this style to container div.

style="white-space: pre;"

More info can be found at https://developer.mozilla.org/en-US/docs/Web/CSS/white-space

<p style="white-space: pre;">_x000D_
    This is normal text._x000D_
</p>_x000D_
<p style="white-space: pre;">_x000D_
    This _x000D_
  text _x000D_
  contains _x000D_
  new lines._x000D_
</p>

another way of doing this is

int minLavel = Convert.ToInt32(dt.Select("AccountLevel=min(AccountLevel)")[0][0]);

I am not sure on the performace part but this does give the correct output

Update: I have found a better/proper way to solve this problem using a BehaviorSubject or an Observable rather than an EventEmitter. Please see this answer: https://stackoverflow.com/a/35568924/215945

Also, the Angular docs now have a cookbook example that uses a Subject.

Original/outdated/wrong answer: again, don't use an EventEmitter in a service. That is an anti-pattern.

Using beta.1... NavService contains the EventEmiter. Component Navigation emits events via the service, and component ObservingComponent subscribes to the events.

nav.service.ts

import {EventEmitter} from 'angular2/core';
export class NavService {
  navchange: EventEmitter<number> = new EventEmitter();
  constructor() {}
  emitNavChangeEvent(number) {
    this.navchange.emit(number);
  }
  getNavChangeEmitter() {
    return this.navchange;
  }
}

components.ts

import {Component} from 'angular2/core';
import {NavService} from '../services/NavService';

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number = 0;
  subscription: any;
  constructor(private navService:NavService) {}
  ngOnInit() {
    this.subscription = this.navService.getNavChangeEmitter()
      .subscribe(item => this.selectedNavItem(item));
  }
  selectedNavItem(item: number) {
    this.item = item;
  }
  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
    <div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>
  `,
})
export class Navigation {
  item = 1;
  constructor(private navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this.navService.emitNavChangeEvent(item);
  }
}

Plunker

Please add define('FS_METHOD','direct'); in wo-config.php

One possible solution is:

<h:panelGroup rendered="#{bean.row == 10}">
    <div class="text-success">
        <h:outputText value="#{bean.row}"/>
    </div>
</h:panelGroup>

#pragma is used to send non-portable (as in this compiler only) messages to the compiler. Things like disabling certain warnings and packing structs are common reasons. Disabling specific warnings is particularly useful if you compile with the warnings as errors flag turned on.

#pragma pack specifically is used to indicate that the struct being packed should not have its members aligned. It's useful when you have a memory mapped interface to a piece of hardware and need to be able to control exactly where the different struct members point. It is notably not a good speed optimization, since most machines are much faster at dealing with aligned data.

Codes explains itself I guess. CGFloat difference1 and difference2 declared in same class private interface. Good if contentSize stays same.

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
        {

        CGFloat contentOffSet = scrollView.contentOffset.y;
        CGFloat contentHeight = scrollView.contentSize.height;

        difference1 = contentHeight - contentOffSet;

        if (difference1 > difference2) {
            NSLog(@"Up");
        }else{
            NSLog(@"Down");
        }

        difference2 = contentHeight - contentOffSet;

       }

About hyperlinks:

The main use of anchor tags - <a></a> - is as hyperlinks. That basically means that they take you somewhere. Hyperlinks require the href property, because it specifies a location.

Hash:

A hash - # within a hyperlink specifies an html element id to which the window should be scrolled.

href="#some-id" would scroll to an element on the current page such as <div id="some-id">.

href="//site.com/#some-id" would go to site.com and scroll to the id on that page.

Scroll to Top:

href="#" doesn't specify an id name, but does have a corresponding location - the top of the page. Clicking an anchor with href="#" will move the scroll position to the top.

See this demo.

This is the expected behavior according to the w3 documentation.

Hyperlink placeholders:

An example where a hyperlink placeholder makes sense is within template previews. On single page demos for templates, I have often seen <a href="#"> so that the anchor tag is a hyperlink, but doesn't go anywhere. Why not leave the href property blank? A blank href property is actually a hyperlink to the current page. In other words, it will cause a page refresh. As I discussed, href="#" is also a hyperlink, and causes scrolling. Therefore, the best solution for hyperlink placeholders is actually href="#!" The idea here is that there hopefully isn't an element on the page with id="!" (who does that!?) and the hyperlink therefore refers to nothing - so nothing happens.

About anchor tags:

Another question that you may be wondering is, "Why not just leave the href property off?". A common response I've heard is that the href property is required, so it "should" be present on anchors. This is FALSE! The href property is required only for an anchor to actually be a hyperlink! Read this from w3. So, why not just leave it off for placeholders? Browsers render default styles for elements and will change the default style of an anchor tag that doesn't have the href property. Instead, it will be considered like regular text. It even changes the browser's behavior regarding the element. The status bar (bottom of the screen) will not be displayed when hovering on an anchor without the href property. It is best to use a placeholder href value on an anchor to ensure it is treated as a hyperlink.

See this demo demonstrating style and behavior differences.

I don't like having to change my signature to use the HttpCreateResponse type, so I came up with a little bit of an extended solution to hide that.

public class HttpActionResult : IHttpActionResult
{
    public HttpActionResult(HttpRequestMessage request) : this(request, HttpStatusCode.OK)
    {
    }

    public HttpActionResult(HttpRequestMessage request, HttpStatusCode code) : this(request, code, null)
    {
    }

    public HttpActionResult(HttpRequestMessage request, HttpStatusCode code, object result)
    {
        Request = request;
        Code = code;
        Result = result;
    }

    public HttpRequestMessage Request { get; }
    public HttpStatusCode Code { get; }
    public object Result { get; }

    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        return Task.FromResult(Request.CreateResponse(Code, Result));
    }
}

You can then add a method to your ApiController (or better your base controller) like this:

protected IHttpActionResult CustomResult(HttpStatusCode code, object data) 
{
    // Request here is the property on the controller.
    return new HttpActionResult(Request, code, data);
}

Then you can return it just like any of the built in methods:

[HttpPost]
public IHttpActionResult Post(Model model)
{
    return model.Id == 1 ?
                Ok() :
                CustomResult(HttpStatusCode.NotAcceptable, new { 
                    data = model, 
                    error = "The ID needs to be 1." 
                });
}

This works in all chrome, IE, Firefox.

In Database > table > field type .for example set the symbol column TO varchar(2) utf8_bin php code:

$symbol = '£';
echo mb_convert_encoding($symbol, 'UTF-8', 'HTML-ENTITIES');
or 
html_entity_decode($symbol, ENT_NOQUOTES, 'UTF-8');

And also make sure set the HTML OR XML encoding to encoding="UTF-8"

Note: You should make sure that database, document type and php code all have a same encoding

How ever the better solution would be using £

You need to give a function to be called after the time delay as the second argument to after:

after(delay_ms, callback=None, *args)

Registers an alarm callback that is called after a given time.

So what you really want to do is this:

tiles_letter = ['a', 'b', 'c', 'd', 'e']

def add_letter():
    rand = random.choice(tiles_letter)
    tile_frame = Label(frame, text=rand)
    tile_frame.pack()
    root.after(500, add_letter)
    tiles_letter.remove(rand)  # remove that tile from list of tiles


root.after(0, add_letter)  # add_letter will run as soon as the mainloop starts.
root.mainloop()

You also need to schedule the function to be called again by repeating the call to after inside the callback function, since after only executes the given function once. This is also noted in the documentation:

The callback is only called once for each call to this method. To keep calling the callback, you need to reregister the callback inside itself

Note that your example will throw an exception as soon as you've exhausted all the entries in tiles_letter, so you need to change your logic to handle that case whichever way you want. The simplest thing would be to add a check at the beginning of add_letter to make sure the list isn't empty, and just return if it is:

def add_letter():
    if not tiles_letter:
        return
    rand = random.choice(tiles_letter)
    tile_frame = Label(frame, text=rand)
    tile_frame.pack()
    root.after(500, add_letter)
    tiles_letter.remove(rand)  # remove that tile from list of tiles

Live-Demo: repl.it

You can change layout visibility just in the same way as for regular view. Use setVisibility(View.GONE) etc. All layouts are just Views, they have View as their parent.

Sure, a div can have as many classes as you want (this is both regarding to bootstrap and HTML in general):

<div class="active dropdown-toggle"></div>

Just separate the classes by space.

Also: Keep in mind some bootstrap classes are supposed to be used for the same stuff but in different cases (for example alignment classes, you might want something aligned left, right or center, but it has to be only one of them) and you shouldn't use them together, or you'd get an unexpected result, basically what will happen is that the class with the highest specificity will be the one applied (or if they have the same then it'll be the one that's defined last on the CSS). So you better avoid doing stuff like this:

<p class="text-center text-left">Some text</p>

Both do the same work as they are used for routing purposes in SPA(Single Page Application).

1. Angular Routing - per $routeProvider docs

URLs to controllers and views (HTML partials). It watches $location.url() and tries to map the path to an existing route definition.

HTML

<div ng-view></div>

Above tag will render the template from the $routeProvider.when() condition which you had mentioned in .config (configuration phase) of angular

Limitations:-

• The page can only contain single ng-view on page
• If your SPA has multiple small components on the page that you wanted to render based on some conditions, $routeProvider fails. (to achieve that, we need to use directives like ng-include, ng-switch, ng-if, ng-show, which looks bad to have them in SPA)
• You can not relate between two routes like parent and child relationship.
• You cannot show and hide a part of the view based on url pattern.

2. ui-router - per $stateProvider docs

AngularUI Router is a routing framework for AngularJS, which allows you to organize the parts of your interface into a state machine. UI-Router is organized around states, which may optionally have routes, as well as other behavior, attached.

Multiple & Named Views

Another great feature is the ability to have multiple ui-views in a template.

While multiple parallel views are a powerful feature, you'll often be able to manage your interfaces more effectively by nesting your views, and pairing those views with nested states.

HTML

<div ui-view>
    <div ui-view='header'></div>
    <div ui-view='content'></div>
    <div ui-view='footer'></div>
</div>

The majority of ui-router's power is it can manage nested state & views.

Pros

• You can have multiple ui-view on single page
• Various views can be nested in each other and maintained by defining state in routing phase.
• We can have child & parent relationship here, simply like inheritance in state, also you could define sibling states.
• You could change the ui-view="some" of state just by using absolute routing using @ with state name.
• Another way you could do relative routing is by using only @ to change ui-view="some". This will replace the ui-view rather than checking if it is nested or not.
• Here you could use ui-sref to create a href URL dynamically on the basis of URL mentioned in a state, also you could give a state params in the json format.

For more Information Angular ui-router

For better flexibility with various nested view with states, I'd prefer you to go for ui-router

Give the div "runat="server" and an id and you can reference it in your code behind.

<div runat="server" id="theDiv">

In code behind:

{
    theDiv.Visible = false;
}

In Designer.cs page:

 protected global::System.Web.UI.HtmlControls.HtmlGenericControl theDiv;

This one works fine

use try { as above

use Catch as above but comment out the echo lines
} catch (phpmailerException $e) { 
//echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {   
//echo $e->getMessage(); //Boring error messages from anything else!
}

Then add this

if ($e) {
//enter yor error message or redirect the user
} else {
//do something else 
}

If you want the dot or other characters with a special meaning in regexes to be a normal character, you have to escape it with a backslash. Since regexes in Java are normal Java strings, you need to escape the backslash itself, so you need two backslashes e.g. \\.

You can change your model method to property and use it in serializer with this approach.

class Foo(models.Model):
    . . .
    @property
    def my_field(self):
        return stuff
    . . .

class FooSerializer(ModelSerializer):
    my_field = serializers.ReadOnlyField(source='my_field')

    class Meta:
        model = Foo
        fields = ('my_field',)

Edit: With recent versions of rest framework (I tried 3.3.3), you don't need to change to property. Model method will just work fine.

jQuery 3

As of jQuery 3, removeAttr does not set the corresponding property to false anymore:

Prior to jQuery 3.0, using .removeAttr() on a boolean attribute such as checked, selected, or readonly would also set the corresponding named property to false. This behavior was required for ancient versions of Internet Explorer but is not correct for modern browsers because the attribute represents the initial value and the property represents the current (dynamic) value.

It is almost always a mistake to use .removeAttr( "checked" ) on a DOM element. The only time it might be useful is if the DOM is later going to be serialized back to an HTML string. In all other cases, .prop( "checked", false ) should be used instead.

Changelog

Hence only .prop('checked',false) is correct way when using this version.

Original answer (from 2011):

For attributes which have underlying boolean properties (of which checked is one), removeAttr automatically sets the underlying property to false. (Note that this is among the backwards-compatibility "fixes" added in jQuery 1.6.1).

So, either will work... but the second example you gave (using prop) is the more correct of the two. If your goal is to uncheck the checkbox, you really do want to affect the property, not the attribute, and there's no need to go through removeAttr to do that.

You need to

using System.Linq;

to use IEnumerable options at your List.

Can't believe this thread was going on for so long. You would get this error if you got distracted and used [] instead of (), at least my case.

Pop is a method on the list data type, https://docs.python.org/2/tutorial/datastructures.html#more-on-lists

Therefore, you shouldn't be using pop as if it was a list itself, pop[0]. It's a method that takes an optional parameter representing an index, so as Tushar Palawat pointed out in one of the answers that didn't get approved, the correct adjustment which will fix the example above is:

listb.pop(0)

If you don't believe, run a sample such as:

if __name__ == '__main__':
  listb = ["-test"]
  if( listb[0] == "-test"):
    print(listb.pop(0))

Other adjustments would work as well, but it feels as they are abusing the Python language. This thread needs to get fixed, not to confuse users.

Addition, a.pop() removes and returns the last item in the list. As a result, a.pop()[0] will get the first character of that last element. It doesn't seem that is what the given code snippet is aiming to achieve.

Declare @MyInt int
Set @MyInt = ( Select Count(*) From MyTable )

If @MyInt > 0
Begin
    Print 'There''s something in the table'
End

I'm not sure if this is your issue, but you have to esacpe the single quote in the print statement with a second single quote. While you can use SELECT to populate the variable, using SET as you have done here is just fine and clearer IMO. In addition, you can be guaranteed that Count(*) will never return a negative value so you need only check whether it is greater than zero.

Save the plot as png

plt.savefig("temp.png")

You can add your own id or class to the body tag of your index page to target all elements on that page with a custom style like so:

<body id="index">
   <h1>...</h1>
</body>

Then you can target the elements you wish to modify with your class or id like so:

#index h1 {
   color:red;
}

I think this is what you are looking for. You need to remove the float: left from the inner nav to center it and make it a inline-block.

.navbar .navbar-nav {
  display: inline-block;
  float: none;
  vertical-align: top;
}

.navbar .navbar-collapse {
  text-align: center;
}

http://jsfiddle.net/bdd9U/2/

Edit: if you only want this effect to happen when the nav isn't collapsed surround it in the appropriate media query.

@media (min-width: 768px) {
    .navbar .navbar-nav {
        display: inline-block;
        float: none;
        vertical-align: top;
    }

    .navbar .navbar-collapse {
        text-align: center;
    }
}

First redirect stderr to stdout — the pipe; then redirect stdout to /dev/null (without changing where stderr is going):

command 2>&1 >/dev/null | grep 'something'

For the details of I/O redirection in all its variety, see the chapter on Redirections in the Bash reference manual.

Note that the sequence of I/O redirections is interpreted left-to-right, but pipes are set up before the I/O redirections are interpreted. File descriptors such as 1 and 2 are references to open file descriptions. The operation 2>&1 makes file descriptor 2 aka stderr refer to the same open file description as file descriptor 1 aka stdout is currently referring to (see dup2() and open()). The operation >/dev/null then changes file descriptor 1 so that it refers to an open file description for /dev/null, but that doesn't change the fact that file descriptor 2 refers to the open file description which file descriptor 1 was originally pointing to — namely, the pipe.

STATIC_ROOT

The absolute path to the directory where ./manage.py collectstatic will collect static files for deployment. Example: STATIC_ROOT="/var/www/example.com/static/"

now the command ./manage.py collectstatic will copy all the static files(ie in static folder in your apps, static files in all paths) to the directory /var/www/example.com/static/. now you only need to serve this directory on apache or nginx..etc.

STATIC_URL

The URL of which the static files in STATIC_ROOT directory are served(by Apache or nginx..etc). Example: /static/ or http://static.example.com/

If you set STATIC_URL = 'http://static.example.com/', then you must serve the STATIC_ROOT folder (ie "/var/www/example.com/static/") by apache or nginx at url 'http://static.example.com/'(so that you can refer the static file '/var/www/example.com/static/jquery.js' with 'http://static.example.com/jquery.js')

Now in your django-templates, you can refer it by:

{% load static %}
<script src="{% static "jquery.js" %}"></script>

which will render:

<script src="http://static.example.com/jquery.js"></script>

"Could not instantiate mail function" is PHPMailer's way of reporting that the call to mail() (in the Mail extension) failed. (So you're using the 'mail' mailer.)

You could try removing the @s before the calls to mail() in PHPMailer::MailSend and seeing what, if any, errors are being silently discarded.

There are a few methods to get metadata about a table:

EXEC sp_help tablename

Will return several result sets, describing the table, it's columns and constraints.

The INFORMATION_SCHEMA views will give you the information you want, though unfortunately you have to query the views and join them manually.

The answer, given by Alexandru is working quite nice. As he said, it is important that this "accessor"-view is added as the last element. Here is some code which did the trick for me:

        ...

        ...

            </LinearLayout>

        </LinearLayout>

    </FrameLayout>

</LinearLayout>

<!-- place a FrameLayout (match_parent) as the last child -->
<FrameLayout
    android:id="@+id/icon_frame_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</FrameLayout>

</TabHost>

in Java:

final MaterialDialog materialDialog = (MaterialDialog) dialogInterface;

FrameLayout frameLayout = (FrameLayout) materialDialog
        .findViewById(R.id.icon_frame_container);

frameLayout.setOnTouchListener(
        new OnSwipeTouchListener(ShowCardActivity.this) {

Skip reading the html and use curl to POST whatever form data you want to submit to the server.

In VB code, when trying to submit an INSERT query, you must submit a double query in the same 'executenonquery' like this:

sqlQuery = "SET IDENTITY_INSERT dbo.TheTable ON; INSERT INTO dbo.TheTable (Col1, COl2) VALUES (Val1, Val2); SET IDENTITY_INSERT dbo.TheTable OFF;"

I used a ; separator instead of a GO.

Works for me. Late but efficient!

This is strange but Logger.getLogger("global") does not work in my setup (as well as Logger.getLogger(Logger.GLOBAL_LOGGER_NAME)).

However Logger.getLogger("") does the job well.

Iterating a list and removing multiple items using a find. Response contains an array of integers. $('#OneSelectList') is a select list.

If you want to know the specific version then you need to check composer.lock file and search For

"name": "laravel/framework",

you will find your version in next line

"version": "v5.7.9",

As pointed out by others, define studentType outside the function. One more thing, even if you do that, do not create a local studentType instance inside the function. The instance is on the function stack and will not be available when you try to return it. One thing you can however do is create studentType dynamically and return the pointer to it outside the function.

In contrast to what the accepted answer proposes, the documentation says that for JSONArray() you must use put(value) no add(value).

There aren't any quotes. It's just VS debugger. Try printing to the console or saving to a file and you'll see. As a side note: always dispose disposable objects:

using (var stringWriter = new StringWriter())
using (var xmlTextWriter = XmlWriter.Create(stringWriter))
{
    xmlDoc.WriteTo(xmlTextWriter);
    xmlTextWriter.Flush();
    return stringWriter.GetStringBuilder().ToString();
}

DESCRIBE FORMATTED my_table;

or

DESCRIBE FORMATTED my_table PARTITION (my_column='my_value');

You can use this:

$(document).ready(function() {
    $("#tabs").tabs();
    $('#action').click(function() {
        var selected = $("#tabs").tabs("option", "selected");
        $("#tabs").tabs("option", "selected", selected + 1);
    });
});

Also consider changing the input type as button instead of submit unless you want to submit the page.

This code is working fine for me in a loop

$remove = array(
    "market_value",
    "sector_id"
);

foreach($remove as $key){

}

You can use JavaScript like... Just give the proper path of your json file...

<!doctype html>
<html>
    <head>
        <script type="text/javascript" src="abc.json"></script>
        <script type="text/javascript" >
            function load() {
                var mydata = JSON.parse(data);
                alert(mydata.length);

                var div = document.getElementById('data');

                for(var i = 0;i < mydata.length; i++)
                {
                    div.innerHTML = div.innerHTML + "<p class='inner' id="+i+">"+ mydata[i].name +"</p>" + "<br>";
                }
            }
        </script>
    </head>
    <body onload="load()">
        <div id="data">

        </div>
    </body>
</html>

Simply getting the data and appending it to a div... Initially printing the length in alert.

Here is my Json file: abc.json

data = '[{"name" : "Riyaz"},{"name" : "Javed"},{"name" : "Arun"},{"name" : "Sunil"},{"name" : "Rahul"},{"name" : "Anita"}]';

If I'm correct, you're looking for the socket.gethostname function:

>> import socket
>> socket.gethostname()
'terminus'

there is an answer but i did not understand why is not working;

var anyDuplicate = enumerable.GroupBy(x => x.Key).Any(g => g.Count() > 1);

my solution is like that in this situation;

var duplicates = model.list
                    .GroupBy(s => s.SAME_ID)
                    .Where(g => g.Count() > 1).Count() > 0;
if(duplicates) {
    doSomething();
}

Here is the one of the better solutions.

DECLARE @i int
            DECLARE @curren_val int
            DECLARE @numrows int
            create table #Practitioner (idx int IDENTITY(1,1), PractitionerId int)
            INSERT INTO #Practitioner (PractitionerId) values (10),(20),(30)
            SET @i = 1
            SET @numrows = (SELECT COUNT(*) FROM #Practitioner)
            IF @numrows > 0
            WHILE (@i <= (SELECT MAX(idx) FROM #Practitioner))
            BEGIN

                SET @curren_val = (SELECT PractitionerId FROM #Practitioner WHERE idx = @i)

                --Do something with Id here
                PRINT @curren_val
                SET @i = @i + 1
            END

Here i've add some values in the table beacuse, initially it is empty.

We can access or we can do anything in the body of the loop and we can access the idx by defining it inside the table definition.

              BEGIN
                SET @curren_val = (SELECT PractitionerId FROM #Practitioner WHERE idx = @i)

                --Do something with Id here

                PRINT @curren_val
                SET @i = @i + 1
            END

All methods that are accessible are inherited by subclasses.

From the Sun Java Tutorials:

A subclass inherits all of the public and protected members of its parent, no matter what package the subclass is in. If the subclass is in the same package as its parent, it also inherits the package-private members of the parent. You can use the inherited members as is, replace them, hide them, or supplement them with new members

The only difference with inherited static (class) methods and inherited non-static (instance) methods is that when you write a new static method with the same signature, the old static method is just hidden, not overridden.

From the page on the difference between overriding and hiding.

The distinction between hiding and overriding has important implications. The version of the overridden method that gets invoked is the one in the subclass. The version of the hidden method that gets invoked depends on whether it is invoked from the superclass or the subclass

Roman Samoylenko's answer was correct except the function has changed. The correct answer is

Glide.with(context)
                .load(yourImage)
                .apply(RequestOptions.circleCropTransform())
                .into(imageView);

Keep in mind if you are wanting to test this component you will want to inject the window. Use the @Inject() function to inject the window object by naming it using a string token like detailed in this duplicate

Can you set the ActionBar before you set the Contient View? This order would be better:

 @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ActionBar actionBar =getSupportActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);            
  }

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

I use this SFTP API which has SCP called Zehon, it's great, so easy to use with a lot of sample code. Here is the site http://www.zehon.com

i = ++a + ++a + a++;

is

i = 6 + 7 + 7

Working: increment a to 6 (current value 6) + increment a to 7 (current value 7). Sum is 13 now add it to current value of a (=7) and then increment a to 8. Sum is 20 and value of a after the assignment completes is 8.

i = a++ + ++a + ++a;

is

i = 5 + 7 + 8

Working: At the start value of a is 5. Use it in the addition and then increment it to 6 (current value 6). Increment a from current value 6 to 7 to get other operand of +. Sum is 12 and current value of a is 7. Next increment a from 7 to 8 (current value = 8) and add it to previous sum 12 to get 20.

One way, using regular expressions:

>>> s = "how much for the maple syrup? $20.99? That's ridiculous!!!"
>>> re.sub(r'[^\w]', ' ', s)
'how much for the maple syrup   20 99  That s ridiculous   '

• \w will match alphanumeric characters and underscores

• [^\w] will match anything that's not alphanumeric or underscore

Be careful if you are working on localhost ! If you store your cookie in js like this:

document.cookie = "key=value;domain=localhost"

It might not be accessible to your subdomain, like sub.localhost. In order to solve this issue you need to use Virtual Host. For exemple you can configure your virtual host with ServerName localhost.com then you will be able to store your cookie on your domain and subdomain like this:

document.cookie = "key=value;domain=localhost.com"

A bit late to this question, but I created a class with all the handy methods needed to create a fully functional time trial in C#. Rather than your application config, I write the expiry time to the Windows Application Data path, and that will also remain persistent even after the program has closed (it's also tricky to find the path for the average user).

Fully documented and simple to use, I hope someone finds it useful!

public class TimeTrialManager
{
    private long expiryTime=0;
    private string softwareName = "";
    private string userPath="";
    private bool useSeconds = false;

    public TimeTrialManager(string softwareName) {
        this.softwareName = softwareName;
        // Create folder in Windows Application Data folder for persistence:
        userPath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData).ToString() + "\\" + softwareName + "_prefs\\";
        if (!Directory.Exists(userPath)) Directory.CreateDirectory(Path.GetDirectoryName(userPath));
        userPath += "expiryinfo.txt";
    }

    // Use this method to check if the expiry has already been created. If
    // it has, you don't need to call the setExpiryDate() method ever again.
    public bool expiryHasBeenStored(){
        return File.Exists(userPath);
    }

    // Use this to set expiry as the number of days from the current time.
    // This should be called just once in the program's lifetime for that user.
    public void setExpiryDate(double days)  {
        DateTime time = DateTime.Now.AddDays(days);
        expiryTime = time.ToFileTimeUtc();
        storeExpiry(expiryTime.ToString() );
        useSeconds = false;
    }

    // Like above, but set the number of seconds. This should be just used for testing
    // as no sensible time trial would allow the user seconds to test the trial out:
    public void setExpiryTime(double seconds)   {
        DateTime time = DateTime.Now.AddSeconds(seconds);
        expiryTime = time.ToFileTimeUtc();
        storeExpiry(expiryTime.ToString());
        useSeconds = true;
    }

    // Check for this in a background timer or whenever else you wish to check if the time has run out
    public bool trialHasExpired()   {
        if(!File.Exists(userPath)) return false;
        if (expiryTime == 0)    expiryTime = Convert.ToInt64(File.ReadAllText(userPath));
        if (DateTime.Now.ToFileTimeUtc() >= expiryTime) return true; else return false;
    }

    // This method is optional and isn't required to use the core functionality of the class
    // Perhaps use it to tell the user how long he has left to trial the software
    public string expiryAsHumanReadableString(bool remaining=false) {
        DateTime dt = new DateTime();
        dt = DateTime.FromFileTimeUtc(expiryTime);
        if (remaining == false) return dt.ToShortDateString() + " " + dt.ToLongTimeString();
        else {
            if (useSeconds) return dt.Subtract(DateTime.Now).TotalSeconds.ToString();
            else return (dt.Subtract(DateTime.Now).TotalDays ).ToString();
        }
    }

    // This method is private to the class, so no need to worry about it
    private void storeExpiry(string value)  {
        try { File.WriteAllText(userPath, value); }
        catch (Exception ex) { MessageBox.Show(ex.Message); }
    }

}

Here is a typical usage of the above class. Couldn't be simpler!

TimeTrialManager ttm;
private void Form1_Load(object sender, EventArgs e)
{
    ttm = new TimeTrialManager("TestTime");
    if (!ttm.expiryHasBeenStored()) ttm.setExpiryDate(30); // Expires in 30 days time
}

private void timer1_Tick(object sender, EventArgs e)
{
    if (ttm.trialHasExpired()) { MessageBox.Show("Trial over! :("); Environment.Exit(0); }
}

Lets assume you created a Ubuntu VM on your local machine. It's IP address is 192.168.1.104.

You login into VM, and installed Kubernetes. Then you created a pod where nginx image running on it.

1- If you want to access this nginx pod inside your VM, you will create a ClusterIP bound to that pod for example:

$ kubectl expose deployment nginxapp --name=nginxclusterip --port=80 --target-port=8080

Then on your browser you can type ip address of nginxclusterip with port 80, like:

http://10.152.183.2:80

2- If you want to access this nginx pod from your host machine, you will need to expose your deployment with NodePort. For example:

$ kubectl expose deployment nginxapp --name=nginxnodeport --port=80 --target-port=8080 --type=NodePort

Now from your host machine you can access to nginx like:

http://192.168.1.104:31865/

In my dashboard they appear as:

Below is a diagram shows basic relationship.

You may be able to do this by modifying the request options as below. If you are using a self-signed certificate or a missing intermediary, setting strictSSL to false will not force request package to validate the certificate.

var options = {
   host: 'jira.example.com',
   path: '/secure/attachment/206906/update.xlsx',
   strictSSL: false
}

I would like to share my solution as well. It's a little bit more verbose but works as well.

var data = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15];

var chunksize = 4;


var chunks = [];

data.forEach((item)=>{
  if(!chunks.length || chunks[chunks.length-1].length == chunksize)
  chunks.push([]);

  chunks[chunks.length-1].push(item);
});

console.log(chunks);

Output (formatted):

[ [ 1,  2,  3,  4],
  [ 5,  6,  7,  8],
  [ 9, 10, 11, 12],
  [13, 14, 15    ] ]

You could set the path to a constant like this and set it using express.

const viewsPath = path.join(__dirname, '../views') 
app.set('view engine','hbs')

 app.set('views', viewsPath)

 app.get('/', function(req, res){

 res.render("index");

});

This worked for me

In addition to the answers above:

The real power of .then is the possibility to chain ajax calls in a fluent way, and thus avoiding callback hell.

For example:

$.getJSON( 'dataservice/General', {action:'getSessionUser'} )
    .then( function( user ) {
        console.log( user );
        return $.getJSON( 'dataservice/Address', {action:'getFirstAddress'} );
    })
    .then( function( address ) {
        console.log( address );
    })

Here the second .then follows the returned $.getJSON

work fine like that: return moment(status.created_at).locale('es').fromNow();

In C++20 you'll be able to use std::format to do this:

unsigned char a = -58;
std::cout << std::format("{:b}", a);

Output:

11000110

In the meantime you can use the {fmt} library, std::format is based on. {fmt} also provides the print function that makes this even easier and more efficient (godbolt):

unsigned char a = -58;
fmt::print("{:b}", a);

Disclaimer: I'm the author of {fmt} and C++20 std::format.

As the Jquery replaceWith() code was too bulky, tricky and complicated, here's my own solution. =)

The best way is to use outerHTML property, but it is not crossbrowsered yet, so I did some trick, weird enough, but simple.

Here is the code

var str = '<a href="http://www.com">item to replace</a>'; //it can be anything
var Obj = document.getElementById('TargetObject'); //any element to be fully replaced
if(Obj.outerHTML) { //if outerHTML is supported
    Obj.outerHTML=str; ///it's simple replacement of whole element with contents of str var
}
else { //if outerHTML is not supported, there is a weird but crossbrowsered trick
    var tmpObj=document.createElement("div");
    tmpObj.innerHTML='<!--THIS DATA SHOULD BE REPLACED-->';
    ObjParent=Obj.parentNode; //Okey, element should be parented
    ObjParent.replaceChild(tmpObj,Obj); //here we placing our temporary data instead of our target, so we can find it then and replace it into whatever we want to replace to
    ObjParent.innerHTML=ObjParent.innerHTML.replace('<div><!--THIS DATA SHOULD BE REPLACED--></div>',str);
}

That's all

There are two operators for type testing: E is T tests for E an instance of type T while E is! T tests for E not an instance of type T.

Note that E is Object is always true, and null is T is always false unless T===Object.

Load default server 404 page, if you have one, e.g. defined for apache:

if(strstr($_SERVER['REQUEST_URI'],'index.php')){
  header('HTTP/1.0 404 Not Found');
  readfile('404missing.html');
  exit();
}

A keystore needs a keystore file. The KeyStore class needs a FileInputStream. But if you supply null (instead of FileInputStream instance) an empty keystore will be loaded. Once you create a keystore, you can verify its integrity using keytool.

Following code creates an empty keystore with empty password

  KeyStore ks2 = KeyStore.getInstance("jks");
  ks2.load(null,"".toCharArray());
  FileOutputStream out = new FileOutputStream("C:\\mykeytore.keystore");
  ks2.store(out, "".toCharArray());

Once you have the keystore, importing certificate is very easy. Checkout this link for the sample code.

To add non-breaking space or real space to your text in html, you can use the   character entity.

A short answer is to add the following options when the JVM is started.

JAVA_OPTS=" $JAVA_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8080"

If you don't want to change to numeric you can try this.

> as.vector(t(df)[,1])
[1] 1.0 2.0 2.6

another solution is catching onClick event and for aggregate data to js function you can

.hmtl.erb

<%= link_to "Action", 'javascript:;', class: 'my-class', data: { 'array' => %w(foo bar) } %>

.js

// handle my-class click
$('a.my-class').on('click', function () {
  var link = $(this);
  var array = link.data('array');
});

I prefer to use date-fns library for date manipulating. It is really great modular and consistent tool. You can get start and end of the day this way:

var startOfDay = dateFns.startOfDay;_x000D_
var endOfDay = dateFns.endOfDay;_x000D_
_x000D_
console.log('start of day ==> ', startOfDay(new Date('2015-11-11')));_x000D_
console.log('end of day ==> ', endOfDay(new Date('2015-11-11')));

<script src="https://cdnjs.cloudflare.com/ajax/libs/date-fns/1.29.0/date_fns.min.js"></script>

I'm not entirely sure what you're after but this sounds like it can be achieved by storing the state of the input elements (or the div?) as a variable:

$('div').each(function(){

    var childInputHasFocus = false;

    $(this).hover(function(){
        if (childInputHasFocus) {
            // do something
        } else { }
    }, function() {
        if (childInputHasFocus) {
            // do something
        } else { }
    });

    $('input', this)
        .focus(function(){
            childInputHasFocus = true;
        })
        .blur(function(){
            childInputHasFocus = false;
        });
});

If you are using Android Studio 3.2 & above,then issue will be solved by adding google() & jcenter() to build.gradle of the project:

repositories {
        google()
        jcenter()
}

I have try with the SCFRench and with the Ru Hasha on octave.

And finally it works: but I have done some modification

function message = makefuns
    assignin('base','fun1', @fun1);   % Ru Hasha
    assignin('base', 'fun2', @fun2);  % Ru Hasha
    message.fun1=@fun1;               % SCFrench
    message.fun2=@fun2;               % SCFrench
end

function y=fun1(x)
    y=x;
end

function z=fun2
    z=1;
end

Can be called in other 'm' file:

printf("%d\n", makefuns.fun1(123));
printf("%d\n", makefuns.fun2());

update:

I added an answer because neither the +72 nor the +20 worked in octave for me. The one I wrote works perfectly (and I tested it last Friday when I later wrote the post).

You can either use the answer from the duplicate link pointed by nvm.

Or you can resolve conflicts by using their changes (but some of your changes might be kept if they don't conflict with remote version):

git pull -s recursive -X theirs

The free and open-source program called cabextract will list and extract the contents of not just .cab-files, but Macrovision's archives too:

% cabextract /tmp/QLWREL.EXE
Extracting cabinet: /tmp/QLWREL.EXE
  extracting ikernel.dll
  extracting IsProBENT.tlb
  ....
  extracting IScript.dll
  extracting iKernel.rgs

All done, no errors.

Actually I think that more general approach to loop through dictionary is to use iteritems():

# get tuples of term, courses
for term, term_courses in courses.iteritems():
    # get tuples of course number, info
    for course, info in term_courses.iteritems():
        # loop through info
        for k, v in info.iteritems():
            print k, v

output:

assistant Peter C.
prereq cs101
...
name Programming a Robotic Car
teacher Sebastian

Or, as Matthias mentioned in comments, if you don't need keys, you can just use itervalues():

for term_courses in courses.itervalues():
    for info in term_courses.itervalues():
        for k, v in info.iteritems():
            print k, v

The following captures stdout and stderr of the process in a single variable. It is Python 2 and 3 compatible:

from subprocess import check_output, CalledProcessError, STDOUT

command = ["ls", "-l"]
try:
    output = check_output(command, stderr=STDOUT).decode()
    success = True 
except CalledProcessError as e:
    output = e.output.decode()
    success = False

If your command is a string rather than an array, prefix this with:

import shlex
command = shlex.split(command)

use only org.hibernate.dialect.OracleDialect Remove 10g,9 etc.

Binding = your textual representation of a specific column gets mapped to a physical column in some table, in some database, on some server.

Multipart identifier could be: MyDatabase.dbo.MyTable. If you get any of these identifiers wrong, then you have a multipart identifier that cannot be mapped.

The best way to avoid it is to write the query right the first time, or use a plugin for management studio that provides intellisense and thus help you out by avoiding typos.

I have done the same percentage calculator for one of my app where we need to show the percentage saved if you choose a "Yearly Plan" over the "Monthly Plan". It helps you to save a specific amount of money in the given period. I have used it for the subscriptions.

Monthly paid for a year - 2028 Yearly paid one time - 1699

1699 is a 16.22% decrease of 2028.

Formula: Percentage of decrease = |2028 - 1699|/2028 = 329/2028 = 0.1622 = 16.22%

I hope that helps someone looking for the same kind of implementation.

func calculatePercentage(monthly: Double, yearly: Double) -> Double {
    let totalMonthlyInYear = monthly * 12
    let result = ((totalMonthlyInYear-yearly)/totalMonthlyInYear)*100
    print("percentage is -",result)
    return result.rounded(toPlaces: 0)
}

Usage:

 let savingsPercentage = self.calculatePercentage(monthly: Double( monthlyProduct.price), yearly: Double(annualProduct.price))
 self.btnPlanDiscount.setTitle("Save \(Int(savingsPercentage))%",for: .normal)

The extension usage for rounding up the percentage over the Double:

extension Double {
/// Rounds the double to decimal places value
func rounded(toPlaces places:Int) -> Double {
    let divisor = pow(10.0, Double(places))
    return (self * divisor).rounded() / divisor
   }
}

I have attached the image for understanding the same.

Thanks

If you don't want the 2-way binding via [(ngModel)], do this:

<select (change)="selectedAccountName = $event.target.value">
  <option *ngFor="let acct of accountsList" [ngValue]="acct">{{ acct.name }}</option>
</select>

Just tested on my project on Angular 4 and it works! The accountsList is an array of Account objects in which name is a property of Account.

Interesting observation:
[ngValue]="acct" exerts the same result as [ngValue]="acct.name".
Don't know how Angular 4 accomplish it!

Structure in C

First you need to declare your structure:

struct mystruct{
 char element_1,
 char element_2
};

Instantiate C structure

Once you declared your structure , you can instantiate a variable that has as type your structure using either:

mystruct struct_example;

or :

mystruct* struct_example;

For the first use case you can access the varaiable eleemnet using the following syntax: struct_example.element_1 = 5;

For the second use case which is having a pointer to variable of type your structure, to be able to access the variable structure you need an arrow:

struct_example->element_1 = 5;

All of you use some strange and complex regex patterns x)

Here's my solution without preg_match :

function getEnumTypes($table, $field) {
    $query = $this->db->prepare("SHOW COLUMNS FROM $table WHERE Field = ?");
    try {$query->execute(array($field));} catch (Exception $e) {error_log($e->getMessage());}
    $types = $query->fetchAll(PDO::FETCH_COLUMN|PDO::FETCH_UNIQUE, 1)[$field];
    return explode("','", trim($types, "enum()'"));
}

Date.parse() isn't a constructor, its a static method.

So, just use

var timeInMillis = Date.parse(s);

instead of

var timeInMillis = new Date.parse(s);

There are two ways to do that (Python 2.6+):

static method

class Klass(object):
    @staticmethod
    def static_method():
        print "Hello World"

Klass.static_method()

module

your module file, called klass.py

def static_method():
    print "Hello World"

your code:

import klass

klass.static_method()

NOTE: This is mentioned in the question but restarting Visual Studio fixes the issue in most cases.

Updating Visual Studio to 'Update 2' got it working again.

Tools -> Extensions and Updates ->Visual Studio Update 2

As mentioned in the question and the link i posted therein, I'd already updated NuGet Package Manager to 3.4.4 prior to this and restarted to no avail, so I don't know if the combination of both these actions worked.

Here is a little more fun. I've found that very often NumPy does exactly what I wish it would do - sometimes it's faster for me to just try things than it is to read the docs. Actually a mixture of both is best.

I think your answer is fine (and it's OK to accept it if you like). This is just "extra".

import numpy as np

a = np.arange(4,10).reshape(2,3)

wh = np.where(a>7)
gt = a>7
x  = np.where(gt)

print "wh: ", wh
print "gt: ", gt
print "x:  ", x

gives:

wh:  (array([1, 1]), array([1, 2]))
gt:  [[False False False]
      [False  True  True]]
x:   (array([1, 1]), array([1, 2]))

... but:

print "a[wh]: ", a[wh]
print "a[gt]  ", a[gt]
print "a[x]:  ", a[x]

gives:

a[wh]:  [8 9]
a[gt]   [8 9]
a[x]:   [8 9]

Using earlier ideas; assuming sha1 is 40 characters; and chasing references (yea, should delete the debug print lines :-):

git reflog | awk '
$3 == "checkout:" && (sha == "" || sha == $1 ) {
  from=$(NF - 2)
  to=$NF
  print from, to, length(from) > "/dev/stderr"
  if (length(from) != 40) { print from ; exit; }
  sha=substr(from, 1, 7)
  print sha > "/dev/stderr"
}
'

gives the raw output:

$ git status
HEAD detached at 147049c
[...]
$ ./gime-branch.sh
a47be8d2167641088b66bf8f5c2bf7d3da0c642c HEAD^ 40
a47be8d
master HEAD^ 6
master

I don't think it will make a significant difference in compile time but #pragma once is very well supported across compilers but not actually part of the standard. The preprocessor may be a little faster with it as it is more simple to understand your exact intent.

#pragma once is less prone to making mistakes and it is less code to type.

To speed up compile time more just forward declare instead of including in .h files when you can.

I prefer to use #pragma once.

See this wikipedia article about the possibility of using both.

The error means that you're navigating to a view whose model is declared as typeof Foo (by using @model Foo), but you actually passed it a model which is typeof Bar (note the term dictionary is used because a model is passed to the view via a ViewDataDictionary).

The error can be caused by

Passing the wrong model from a controller method to a view (or partial view)

Common examples include using a query that creates an anonymous object (or collection of anonymous objects) and passing it to the view

var model = db.Foos.Select(x => new
{
    ID = x.ID,
    Name = x.Name
};
return View(model); // passes an anonymous object to a view declared with @model Foo

or passing a collection of objects to a view that expect a single object

var model = db.Foos.Where(x => x.ID == id);
return View(model); // passes IEnumerable<Foo> to a view declared with @model Foo

The error can be easily identified at compile time by explicitly declaring the model type in the controller to match the model in the view rather than using var.

Passing the wrong model from a view to a partial view

Given the following model

public class Foo
{
    public Bar MyBar { get; set; }
}

and a main view declared with @model Foo and a partial view declared with @model Bar, then

Foo model = db.Foos.Where(x => x.ID == id).Include(x => x.Bar).FirstOrDefault();
return View(model);

will return the correct model to the main view. However the exception will be thrown if the view includes

@Html.Partial("_Bar") // or @{ Html.RenderPartial("_Bar"); }

By default, the model passed to the partial view is the model declared in the main view and you need to use

@Html.Partial("_Bar", Model.MyBar) // or @{ Html.RenderPartial("_Bar", Model.MyBar); }

to pass the instance of Bar to the partial view. Note also that if the value of MyBar is null (has not been initialized), then by default Foo will be passed to the partial, in which case, it needs to be

@Html.Partial("_Bar", new Bar())

Declaring a model in a layout

If a layout file includes a model declaration, then all views that use that layout must declare the same model, or a model that derives from that model.

If you want to include the html for a separate model in a Layout, then in the Layout, use @Html.Action(...) to call a [ChildActionOnly] method initializes that model and returns a partial view for it.

In languages that support regular expressions with non-capturing groups:

((?:[^/]*/)*)(.*)

I'll explain the gnarly regex by exploding it...

(
  (?:
    [^/]*
    /
  )
  *
)
(.*)

What the parts mean:

(  -- capture group 1 starts
  (?:  -- non-capturing group starts
    [^/]*  -- greedily match as many non-directory separators as possible
    /  -- match a single directory-separator character
  )  -- non-capturing group ends
  *  -- repeat the non-capturing group zero-or-more times
)  -- capture group 1 ends
(.*)  -- capture all remaining characters in group 2

Example

To test the regular expression, I used the following Perl script...

#!/usr/bin/perl -w

use strict;
use warnings;

sub test {
  my $str = shift;
  my $testname = shift;

  $str =~ m#((?:[^/]*/)*)(.*)#;

  print "$str -- $testname\n";
  print "  1: $1\n";
  print "  2: $2\n\n";
}

test('/var/log/xyz/10032008.log', 'absolute path');
test('var/log/xyz/10032008.log', 'relative path');
test('10032008.log', 'filename-only');
test('/10032008.log', 'file directly under root');

The output of the script...

/var/log/xyz/10032008.log -- absolute path
  1: /var/log/xyz/
  2: 10032008.log

var/log/xyz/10032008.log -- relative path
  1: var/log/xyz/
  2: 10032008.log

10032008.log -- filename-only
  1:
  2: 10032008.log

/10032008.log -- file directly under root
  1: /
  2: 10032008.log

class Object
  def nil_zero?
    self.nil? || self == 0
  end
end

# which lets you do
nil.nil_zero? # returns true
0.nil_zero?   # returns true
1.nil_zero?   # returns false
"a".nil_zero? # returns false

unless discount.nil_zero?
  # do stuff...
end

Beware of the usual disclaimers... great power/responsibility, monkey patching leading to the dark side etc.

delete the assemeblyinfo.cs file from project under properties menu and rebulid it.

Guzzle implements PSR-7. That means that it will by default store the body of a message in a Stream that uses PHP temp streams. To retrieve all the data, you can use casting operator:

$contents = (string) $response->getBody();

You can also do it with

$contents = $response->getBody()->getContents();

The difference between the two approaches is that getContents returns the remaining contents, so that a second call returns nothing unless you seek the position of the stream with rewind or seek .

$stream = $response->getBody();
$contents = $stream->getContents(); // returns all the contents
$contents = $stream->getContents(); // empty string
$stream->rewind(); // Seek to the beginning
$contents = $stream->getContents(); // returns all the contents

Instead, usings PHP's string casting operations, it will reads all the data from the stream from the beginning until the end is reached.

$contents = (string) $response->getBody(); // returns all the contents
$contents = (string) $response->getBody(); // returns all the contents

Documentation: http://docs.guzzlephp.org/en/latest/psr7.html#responses

since others have answered how to do it, I'll answer how it happens line by line.

with FileOpenerCM('file.txt') as fp: # is equal to "with open('file.txt') as fp:"
      fp.write('dummy text')

this is a so-called context manager, anything that comes with a with block is a context manager. so let's see how this happens under the hood.

class FileOpenerCM:
     def __init__(self, file, mode='w'):
         self.file = open(file, mode)
      
     def __enter__(self):
          return self.file
      
     def __exit__(self, exc_type, exc_value, exc_traceback):
         self.file.close()

the first method __init__ is (as you all know) the initialization method of an object. whenever an object is created obj.__init__ is definitely called. and that's the place where you put your all the init kinda code.

the second method __enter__ is a bit interesting. some of you might not have seen it because it is a specific method for context managers. what it returns is the value to be assigned to the variable after the as keyword. in our case, fp.

the last method is the method to run after an error is captured or if the code exits the with block. exc_type, exc_value, exc_traceback variables are the variables that hold the values of the errors that occurred inside with block. for example,

exc_type: TypeError
exc_value: unsupported operand type(s) for +: 'int' and 'str
exc_traceback: <traceback object at 0x6af8ee10bc4d>

from the first two variables, you can get info enough info about the error. honestly, I don't know the use of the third variable, but for me, the first two are enough. if you want to do more research on context managers surely you can do it and note that writing classes are not the only way to write context managers. with contextlib you can write context managers through functions(actually generators) as well. it's totally up to you to have a look at it. you can surely try generator functions with contextlib but as I see classes are much cleaner.

The format of favicon must be square otherwise the browser will stretch it. Unfortunatelly, Internet Explorer < 11 do not support .gif, or .png filetypes, but only Microsoft's .ico format. You can use some "favicon generator" app like: http://favicon-generator.org/

For those situations where width of the items you do want to flex-end is known, you can set their flex to "0 0 ##px" and set the item you want to flex-start with flex:1

This will cause the pseudo flex-start item to fill the container, just format it to text-align:left or whatever.

Internet Explorer and Edge do not support some MP4 formats that Chrome does. You can use ffprobe to see the exact MP4 format. In my case I have these two videos:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'a.mp4':
  Metadata:
    major_brand     : isom
    minor_version   : 512
    compatible_brands: isomiso2avc1mp41

    Metadata:
      handler_name    : VideoHandler

Both play fine in Chrome, but the first one fails in IE and Edge. The problem is that IE and Edge don't support yuv444. You can convert to a shittier colourspace like this:

ffmpeg -i input.mp4 -pix_fmt yuv420p output.mp4

hashMaps can't have duplicate keys. That said, you can create a map with list values:

Map<Integer, List<String>>

However, using this approach will have performance implications.

It's not a Git error message, it's the editor as git uses your default editor.

To solve this:

1. press "i" (i for insert)
2. write your merge message
3. press "esc" (escape)
4. write ":wq" (write & quit)
5. then press enter

Another way (depending on your actual needs): If you want to pop the first n characters and save both the popped characters and the modified string:

s = 'lipsum'
n = 3
a, s = s[:n], s[n:]
print(a)
# lip
print(s)
# sum

The quickest fix is upgrate the pip. Did worked for me:

pip install --upgrade pip
