You could change the @RequestParam type to an Integer and make it not required. This would allow your request to succeed, but it would then be null. You could explicitly set it to your default value in the controller method:

@RequestMapping(value = "/test", method = RequestMethod.POST)
@ResponseBody
public void test(@RequestParam(value = "i", required=false) Integer i) {
    if(i == null) {
        i = 10;
    }
    // ...
}

I have removed the defaultValue from the example above, but you may want to include it if you expect to receive requests where it isn't set at all:

http://example.com/test

Note:- below is the illustration of map and flatmap function, otherwise Optional is primarily designed to be used as a return type only.

As you already may know Optional is a kind of container which may or may not contain a single object, so it can be used wherever you anticipate a null value(You may never see NPE if use Optional properly). For example if you have a method which expects a person object which may be nullable you may want to write the method something like this:

void doSome(Optional<Person> person){
  /*and here you want to retrieve some property phone out of person
    you may write something like this:
  */
  Optional<String> phone = person.map((p)->p.getPhone());
  phone.ifPresent((ph)->dial(ph));
}
class Person{
  private String phone;
  //setter, getters
}

Here you have returned a String type which is automatically wrapped in an Optional type.

If person class looked like this, i.e. phone is also Optional

class Person{
  private Optional<String> phone;
  //setter,getter
}

In this case invoking map function will wrap the returned value in Optional and yield something like:

Optional<Optional<String>> 
//And you may want Optional<String> instead, here comes flatMap

void doSome(Optional<Person> person){
  Optional<String> phone = person.flatMap((p)->p.getPhone());
  phone.ifPresent((ph)->dial(ph));
}

PS; Never call get method (if you need to) on an Optional without checking it with isPresent() unless you can't live without NullPointerExceptions.

If the list is sorted (as happens to be in the example) a binary search on index certainly works.

    public static Dog Find(List<Dog> AllDogs, string Id)
    {
        int p = 0;
        int n = AllDogs.Count;
        while (true)
        {
            int m = (n + p) / 2;
            Dog d = AllDogs[m];
            int r = string.Compare(Id, d.Id);
            if (r == 0)
                return d;
            if (m == p)
                return null;
            if (r < 0)
                n = m;
            if (r > 0)
                p = m;
        }
    }

Not sure what the LINQ version of this would be.

The multi-framework safe shorthand for ready is:

jQuery(function($, undefined) {
    // $ is guaranteed to be short for jQuery in this scope
    // undefined is provided because it could have been overwritten elsewhere
});

This is because jQuery isn't the only framework that uses the $ and undefined variables

I just wanted to extend Alex's great answer to make it appropriate if you happen to want to duplicate an entire set of records:

SET @x=7;
CREATE TEMPORARY TABLE tmp SELECT * FROM invoices;
UPDATE tmp SET id=id+@x;
INSERT INTO invoices SELECT * FROM tmp;

I just had to do this and found Alex's answer a perfect jumping off point!. Of course, you have to set @x to the highest row number in the table (I'm sure you could grab that with a query). This is only useful in this very specific situation, so be careful using it when you don't wish to duplicate all rows. Adjust the math as necessary.

find $HOME -name "hello.c" -print

This will search the whole $HOME (i.e. /home/username/) system for any files named “hello.c” and display their pathnames:

/Users/user/Downloads/hello.c
/Users/user/hello.c

However, it will not match HELLO.C or HellO.C. To match is case insensitive pass the -iname option as follows:

find $HOME -iname "hello.c" -print

Sample outputs:

/Users/user/Downloads/hello.c
/Users/user/Downloads/Y/Hello.C
/Users/user/Downloads/Z/HELLO.c
/Users/user/hello.c

Pass the -type f option to only search for files:

find /dir/to/search -type f -iname "fooBar.conf.sample" -print
find $HOME -type f -iname "fooBar.conf.sample" -print

The -iname works either on GNU or BSD (including OS X) version find command. If your version of find command does not supports -iname, try the following syntax using grep command:

find $HOME | grep -i "hello.c"
find $HOME -name "*" -print | grep -i "hello.c"

OR try

find $HOME -name '[hH][eE][lL][lL][oO].[cC]' -print

Sample outputs:

/Users/user/Downloads/Z/HELLO.C
/Users/user/Downloads/Z/HEllO.c
/Users/user/Downloads/hello.c
/Users/user/hello.c

Change this code:

setTimeout(function(){this.setState({timePassed: true})}, 1000);

to the following:

setTimeout(()=>{this.setState({timePassed: true})}, 1000); 

use following command from mongo shell to drop db

use ; db.dropDatabase();

If you are talking about Datepicker for bootstrap, you set the start date (the min date) by using the following:

$('#datepicker').datepicker('setStartDate', <DATETIME STRING HERE>);

ALTER TABLE TABLE_NAME ADD (COLUMN_NAME_NEW varchar2(4000 char));
update TABLE_NAME set COLUMN_NAME_NEW = COLUMN_NAME;

ALTER TABLE TABLE_NAME DROP COLUMN COLUMN_NAME;
ALTER TABLE TABLE_NAME rename column COLUMN_NAME_NEW to COLUMN_NAME;

If you want to use the font to draw with graphics2d or similar, this works:

InputStream stream = ClassLoader.getSystemClassLoader().getResourceAsStream("roboto-bold.ttf")
Font font = Font.createFont(Font.TRUETYPE_FONT, stream).deriveFont(48f)

For the latest Python download - I have Python 3.6 on Windows. You don't have to wonder. Everything you need is there. Take a breath, and I will show you how to do it.

1. Make sure where you install Python. For me, it was in the following directory

   

   Now, let’s add the Python and pip into environment variable path settings if you are on Windows, so that typing pip or python anywhere call python or pip from where they are installed.

   So, PIP is found under the folder in the above screen "SCRIPTS" Let's add Python and PIP in the environment variable path.

   

   Almost done. Let's test with CMD to install the google package using pip.

    pip install google
   

   

It might also be an OpenJDK bug... (not in this case but it is the same error)

If somebody like me stumbles upon this answer regarding the

java.lang.IllegalArgumentException: Comparison method violates its general contract!

then it might also be a bug in the Java-Version. I have a compareTo running since several years now in some applications. But suddenly it stopped working and throws the error after all compares were done (i compare 6 Attributes before returning "0").

Now I just found this Bugreport of OpenJDK:

• JDK-8210311
• Affects Version/s: 8, 11
• Fix Version/s: 12
• https://bugs.openjdk.java.net/browse/JDK-8210311

I don't remember in which version of ASP.NET MVC (ASP.NET MVC 3+ I believe) / Razor the parameterlabeldeclaration or whatever it's called (parameter: x) feature was introduced, but to me this is definitely the proper way to build a link with an anchor in ASP.NET MVC.

@Html.ActionLink("Some link text", "MyAction", "MyController", protocol: null, hostName: null, fragment: "MyAnchor", routeValues: null, htmlAttributes: null)

Not even Ed Blackburns antipattern argument from this answer can compete with that.

To show a grid line on every tick, add

plt.grid(True)

For example:

import matplotlib.pyplot as plt

points = [
    (0, 10),
    (10, 20),
    (20, 40),
    (60, 100),
]

x = list(map(lambda x: x[0], points))
y = list(map(lambda x: x[1], points))

plt.scatter(x, y)
plt.grid(True)

plt.show()

In addition, you might want to customize the styling (e.g. solid line instead of dashed line), add:

plt.rc('grid', linestyle="-", color='black')

For example:

import matplotlib.pyplot as plt

points = [
    (0, 10),
    (10, 20),
    (20, 40),
    (60, 100),
]

x = list(map(lambda x: x[0], points))
y = list(map(lambda x: x[1], points))

plt.rc('grid', linestyle="-", color='black')
plt.scatter(x, y)
plt.grid(True)

plt.show()

A basically full command is like git push <remote> <local_ref>:<remote_ref>. If you run just git push, git does not know what to do exactly unless you have made some config that helps git to make a decision. In a git repo, we can setup multiple remotes. Also we can push a local ref to any remote ref. The full command is the most straightforward way to make a push. If you want to type fewer words, you have to config first, like --set-upstream.

Simply do the following in the script tags:

<!Doctype html>_x000D_
<html>_x000D_
<head>_x000D_
 <title>Circle Canvas</title>_x000D_
</head>_x000D_
<body>_x000D_
 <canvas id="myCanvas" width="300" height="150" style="border:1px solid _x000D_
#d3d3d3;">_x000D_
 <body>_x000D_
  <script>_x000D_
   var c = document.getElementById("myCanvas");_x000D_
   var ctx = c.getContext("2d");_x000D_
   ctx.beginPath();_x000D_
   ctx.arc(100, 75, 50, 0, 2 * Math.PI);_x000D_
   ctx.stroke();_x000D_
  </script>_x000D_
    </body>_x000D_
</body>_x000D_
</html>

And there you go you got your circle.

As per https://android.stackexchange.com/a/78183/239063 you can run a one line command in Linux to add in an appropriate tar header to extract it.

( printf "\x1f\x8b\x08\x00\x00\x00\x00\x00" ; tail -c +25 backup.ab ) | tar xfvz -

Replace backup.ab with the path to your file.

I would say you have two options:

1. to get all parent divs styled with 100% height (including body and html)

2. to use absolute positioning for one of the parent divs (for example #content) and then all child divs set to height 100%

File.foreach(filename).with_index do |line, line_num|
   puts "#{line_num}: #{line}"
end

This will execute the given block for each line in the file without slurping the entire file into memory. See: IO::foreach.

You can use any:

print any(df.column == 07311954)
True       #true if it contains the number, false otherwise

If you rather want to see how many times '07311954' occurs in a column you can use:

df.column[df.column == 07311954].count()

As shown by @Maglob, the basic approach is to test the conversion from string to date using SimpleDateFormat.parse. That will catch invalid day/month combinations like 2008-02-31.

However, in practice that is rarely enough since SimpleDateFormat.parse is exceedingly liberal. There are two behaviours you might be concerned with:

Invalid characters in the date string Surprisingly, 2008-02-2x will "pass" as a valid date with locale format = "yyyy-MM-dd" for example. Even when isLenient==false.

Years: 2, 3 or 4 digits? You may also want to enforce 4-digit years rather than allowing the default SimpleDateFormat behaviour (which will interpret "12-02-31" differently depending on whether your format was "yyyy-MM-dd" or "yy-MM-dd")

A Strict Solution with the Standard Library

So a complete string to date test could look like this: a combination of regex match, and then a forced date conversion. The trick with the regex is to make it locale-friendly.

  Date parseDate(String maybeDate, String format, boolean lenient) {
    Date date = null;

    // test date string matches format structure using regex
    // - weed out illegal characters and enforce 4-digit year
    // - create the regex based on the local format string
    String reFormat = Pattern.compile("d+|M+").matcher(Matcher.quoteReplacement(format)).replaceAll("\\\\d{1,2}");
    reFormat = Pattern.compile("y+").matcher(reFormat).replaceAll("\\\\d{4}");
    if ( Pattern.compile(reFormat).matcher(maybeDate).matches() ) {

      // date string matches format structure, 
      // - now test it can be converted to a valid date
      SimpleDateFormat sdf = (SimpleDateFormat)DateFormat.getDateInstance();
      sdf.applyPattern(format);
      sdf.setLenient(lenient);
      try { date = sdf.parse(maybeDate); } catch (ParseException e) { }
    } 
    return date;
  } 

  // used like this:
  Date date = parseDate( "21/5/2009", "d/M/yyyy", false);

Note that the regex assumes the format string contains only day, month, year, and separator characters. Aside from that, format can be in any locale format: "d/MM/yy", "yyyy-MM-dd", and so on. The format string for the current locale could be obtained like this:

Locale locale = Locale.getDefault();
SimpleDateFormat sdf = (SimpleDateFormat)DateFormat.getDateInstance(DateFormat.SHORT, locale );
String format = sdf.toPattern();

Joda Time - Better Alternative?

I've been hearing about joda time recently and thought I'd compare. Two points:

1. Seems better at being strict about invalid characters in the date string, unlike SimpleDateFormat
2. Can't see a way to enforce 4-digit years with it yet (but I guess you could create your own DateTimeFormatter for this purpose)

It's quite simple to use:

import org.joda.time.format.*;
import org.joda.time.DateTime;

org.joda.time.DateTime parseDate(String maybeDate, String format) {
  org.joda.time.DateTime date = null;
  try {
    DateTimeFormatter fmt = DateTimeFormat.forPattern(format);
    date =  fmt.parseDateTime(maybeDate);
  } catch (Exception e) { }
  return date;
}

You can use filter() to do that:

var tableRow = $("td").filter(function() {
    return $(this).text() == "foo";
}).closest("tr");

This is a straight way to do this.

The case is simple, but finally quite common ( typical thumbnails scroller with fixed cell size and fixed gap between cells )

var itemCellSize: CGSize = <your cell size>
var itemCellsGap: CGFloat = <gap in between>

override func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
    let pageWidth = (itemCellSize.width + itemCellsGap)
    let itemIndex = (targetContentOffset.pointee.x) / pageWidth
    targetContentOffset.pointee.x = round(itemIndex) * pageWidth - (itemCellsGap / 2)
}

// CollectionViewFlowLayoutDelegate

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
    return itemCellSize
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
    return itemCellsGap
}

Note that there is no reason to call a scrollToOffset or dive into layouts. The native scrolling behaviour already does everything.

Cheers All :)

I don't know Sphinx, but as for Lucene vs a database full-text search, I think that Lucene performance is unmatched. You should be able to do almost any search in less than 10 ms, no matter how many records you have to search, provided that you have set up your Lucene index correctly.

Here comes the biggest hurdle though: personally, I think integrating Lucene in your project is not easy. Sure, it is not too hard to set it up so you can do some basic search, but if you want to get the most out of it, with optimal performance, then you definitely need a good book about Lucene.

As for CPU & RAM requirements, performing a search in Lucene doesn't task your CPU too much, though indexing your data is, although you don't do that too often (maybe once or twice a day), so that isn't much of a hurdle.

It doesn't answer all of your questions but in short, if you have a lot of data to search, and you want great performance, then I think Lucene is definitely the way to go. If you're not going to have that much data to search, then you might as well go for a database full-text search. Setting up a MySQL full-text search is definitely easier in my book.

You can use:

show full processlist

which will list all the connections in MySQL and the current state of connection as well as the query being executed. There's also a shorter variant show processlist; which displays the truncated query as well as the connection stats.

With google-drive-ftp-adapter I have been able to access the My Drive area of Google Drive with the FileZilla FTP client. However, I have not been able to access the Shared with me area.

You can configure which Google account credentials it uses by changing the account property in the configuration.properties file from default to the desired Google account name. See the instructions at http://www.andresoviedo.org/google-drive-ftp-adapter/

You are trying to do a logarithm of something that is not positive.

Logarithms figure out the base after being given a number and the power it was raised to. log(0) means that something raised to the power of 2 is 0. An exponent can never result in 0*, which means that log(0) has no answer, thus throwing the math domain error

*Note: 0^0 can result in 0, but can also result in 1 at the same time. This problem is heavily argued over.

Simply you have to follow the following steps:

1. Power off your machine.
2. Right click on virtual machine name > Settings > Storage
3. Click on Controller : SATA > Add Hard Disk.
4. Choose the new hard disk drive type size and hit create.
5. Discard the machine state.
6. Insert Ubuntu Live CD.
7. Boot from ubuntu live cd.
8. Open "gparted" (It's installed, not need to installation).
9. Check if the system see your new created hard disk.
10. Open Terminal.
11. Type the following code.
12. sudo dd if=/dev/sda of=/dev/sdb (The first is the old partition path, the second is the new partition path).
13. Wait until its finish copying data (This step may take some time according to your host specs).
14. After finish copying, return to gparted and select refresh devices.
15. Select the new partition /dev/sdb it must be typical to the old one after doing dd command.
16. It'll show the expanded space as unlocated data.
17. Delete Swap partition/Extended partition.
18. Right click on root partition /dev/sdb > Resize
19. Allocate the whole space without swap allocation.
20. Create new extended partition > Choose extended > Create
21. Create new linux-swap partition > choose linux-swap > Create
22. Now turn off your running machine.
23. Right click on machine > settings > Storage.
24. Eject ubuntu live cd.
25. Right click on the old hard disk > remove attachment.
26. Now you can start your vm from the newly created hard disk.
27. Check the storage by enter df -kh command.
28. It must show you the new size.

Congratulation, enjoy your free space.

Here is a simple function. No library needed.

I wrote this function to get the top and bottom bounds relative to baseline. If textBaseline is set to alphabetic. What it does is it creates another canvas, and then draws there, and then finds the top most and bottom most non blank pixel. And that is the top and bottom bounds. It returns it as relative, so if height is 20px, and there is nothing below the baseline, then the top bound is -20.

You must supply characters to it. Otherwise it will give you 0 height and 0 width, obviously.

Usage:

alert(measureHeight('40px serif', 40, 'rg').height)

Here is the function:

function measureHeight(aFont, aSize, aChars, aOptions={}) {
    // if you do pass aOptions.ctx, keep in mind that the ctx properties will be changed and not set back. so you should have a devoted canvas for this
    // if you dont pass in a width to aOptions, it will return it to you in the return object
    // the returned width is Math.ceil'ed
    console.error('aChars: "' + aChars + '"');
    var defaultOptions = {
        width: undefined, // if you specify a width then i wont have to use measureText to get the width
        canAndCtx: undefined, // set it to object {can:,ctx:} // if not provided, i will make one
        range: 3
    };

    aOptions.range = aOptions.range || 3; // multiples the aSize by this much

    if (aChars === '') {
        // no characters, so obviously everything is 0
        return {
            relativeBot: 0,
            relativeTop: 0,
            height: 0,
            width: 0
        };
        // otherwise i will get IndexSizeError: Index or size is negative or greater than the allowed amount error somewhere below
    }

    // validateOptionsObj(aOptions, defaultOptions); // not needed because all defaults are undefined

    var can;
    var ctx; 
    if (!aOptions.canAndCtx) {
        can = document.createElement('canvas');;
        can.mozOpaque = 'true'; // improved performanceo on firefox i guess
        ctx = can.getContext('2d');

        // can.style.position = 'absolute';
        // can.style.zIndex = 10000;
        // can.style.left = 0;
        // can.style.top = 0;
        // document.body.appendChild(can);
    } else {
        can = aOptions.canAndCtx.can;
        ctx = aOptions.canAndCtx.ctx;
    }

    var w = aOptions.width;
    if (!w) {
        ctx.textBaseline = 'alphabetic';
        ctx.textAlign = 'left'; 
        ctx.font = aFont;
        w = ctx.measureText(aChars).width;
    }

    w = Math.ceil(w); // needed as i use w in the calc for the loop, it needs to be a whole number

    // must set width/height, as it wont paint outside of the bounds
    can.width = w;
    can.height = aSize * aOptions.range;

    ctx.font = aFont; // need to set the .font again, because after changing width/height it makes it forget for some reason
    ctx.textBaseline = 'alphabetic';
    ctx.textAlign = 'left'; 

    ctx.fillStyle = 'white';

    console.log('w:', w);

    var avgOfRange = (aOptions.range + 1) / 2;
    var yBaseline = Math.ceil(aSize * avgOfRange);
    console.log('yBaseline:', yBaseline);

    ctx.fillText(aChars, 0, yBaseline);

    var yEnd = aSize * aOptions.range;

    var data = ctx.getImageData(0, 0, w, yEnd).data;
    // console.log('data:', data)

    var botBound = -1;
    var topBound = -1;

    // measureHeightY:
    for (y=0; y<=yEnd; y++) {
        for (var x = 0; x < w; x += 1) {
            var n = 4 * (w * y + x);
            var r = data[n];
            var g = data[n + 1];
            var b = data[n + 2];
            // var a = data[n + 3];

            if (r+g+b > 0) { // non black px found
                if (topBound == -1) { 
                    topBound = y;
                }
                botBound = y; // break measureHeightY; // dont break measureHeightY ever, keep going, we till yEnd. so we get proper height for strings like "`." or ":" or "!"
                break;
            }
        }
    }

    return {
        relativeBot: botBound - yBaseline, // relative to baseline of 0 // bottom most row having non-black
        relativeTop: topBound - yBaseline, // relative to baseline of 0 // top most row having non-black
        height: (botBound - topBound) + 1,
        width: w// EDIT: comma has been added to fix old broken code.
    };
}

relativeBot, relativeTop, and height are the useful things in the return object.

Adding to the above-accepted answer so that it helps those who are using tensorflow 2.0

import tensorflow as tf

# some data
c1 = tf.constant([[1, 1, 1], [2, 2, 2]], dtype=tf.float32)
c2 = tf.constant([[2, 2, 2], [3, 3, 3]], dtype=tf.float32)
c3 = tf.constant([[3, 3, 3], [4, 4, 4]], dtype=tf.float32)

# bake layers x1, x2, x3
x1 = tf.keras.layers.Dense(10)(c1)
x2 = tf.keras.layers.Dense(10)(c2)
x3 = tf.keras.layers.Dense(10)(c3)

# merged layer y1
y1 = tf.keras.layers.Concatenate(axis=1)([x1, x2])

# merged layer y2
y2 = tf.keras.layers.Concatenate(axis=1)([y1, x3])

# print info
print("-"*30)
print("x1", x1.shape, "x2", x2.shape, "x3", x3.shape)
print("y1", y1.shape)
print("y2", y2.shape)
print("-"*30)

Result:

Android uses hexadecimal ARGB values, which are formatted as #AARRGGBB. That first pair of letters, the AA, represent the alpha channel. You must convert your decimal opacity values to a hexadecimal value. Here are the steps:

Alpha Hex Value Process

1. Take your opacity as a decimal value and multiply it by 255. So, if you have a block that is 50% opaque the decimal value would be .5. For example: .5 x 255 = 127.5
2. The fraction won't convert to hexadecimal, so you must round your number up or down to the nearest whole number. For example: 127.5 rounds up to 128; 55.25 rounds down to 55.
3. Enter your decimal value in a decimal-to-hexadecimal converter, like http://www.binaryhexconverter.com/decimal-to-hex-converter, and convert your values.
4. If you only get back a single value, prefix it with a zero. For example, if you're trying to get 5% opacity and you're going through this process, you'll end up with the hexadecimal value of D. Add a zero in front of it so it appears as 0D.

That's how you find the alpha channel value. I've taken the liberty to put together a list of values for you. Enjoy!

Hex Opacity Values

• 100% — FF
• 95% — F2
• 90% — E6
• 85% — D9
• 80% — CC
• 75% — BF
• 70% — B3
• 65% — A6
• 60% — 99
• 55% — 8C
• 50% — 80
• 45% — 73
• 40% — 66
• 35% — 59
• 30% — 4D
• 25% — 40
• 20% — 33
• 15% — 26
• 10% — 1A
• 5% — 0D
• 0% — 00

You can use a Deferred objects for ASYNC loading.

function load_img_async(source) {
    return $.Deferred (function (task) {
        var image = new Image();
        image.onload = function () {task.resolve(image);}
        image.onerror = function () {task.reject();}
        image.src=source;
    }).promise();
}

$.when(load_img_async(IMAGE_URL)).done(function (image) {
    $(#id).empty().append(image);
});

Please pay attention: image.onload must be before image.src to prevent problems with cache.

I guess this would rather be a better solution.

Override the following methods as below mentioned in

App\Http\Controller\Auth\RegisterController.php

use Illuminate\Http\Response;

.
.
.

public function showRegistrationForm()
{
    abort(Response::HTTP_NOT_FOUND);
}

public function register(Request $request)
{
    abort(Response::HTTP_NOT_FOUND);
}

i have alreay 2 situations where directives and services/factories didnt play well.

the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).

in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.

i even tried to make a directive with a controller and an isolated-scope

only when i moved everything to a controller and it worked like magic.

Flexible Box Layout Module - 8.1. Aligning with auto margins

Auto margins on flex items have an effect very similar to auto margins in block flow:

• During calculations of flex bases and flexible lengths, auto margins are treated as 0.

• Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Therefore you could use margin-top: auto to distribute the space between the other elements and the last element.

This will position the last element at the bottom.

p:last-of-type {
  margin-top: auto;
}

.container {
  display: flex;
  flex-direction: column;
  border: 1px solid #000;
  min-height: 200px;
  width: 100px;
}
p {
  height: 30px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-top: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
</div>

Likewise, you can also use margin-left: auto or margin-right: auto for the same alignment horizontally.

p:last-of-type {
  margin-left: auto;
}

.container {
  display: flex;
  width: 100%;
  border: 1px solid #000;
}
p {
  height: 50px;
  width: 50px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-left: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
  <p></p>
</div>

([[][a-z \s]+[]])

Above should work given the following explaination

• characters within square brackets[] defines characte class which means pattern should match atleast one charcater mentioned within square brackets

• \s specifies a space

•  + means atleast one of the character mentioned previously to +.

I'm not sure exactly what you mean by "full Git Bash environment", but I get the nice prompt if I do

"C:\Program Files\Git\bin\sh.exe" --login

In PowerShell

& 'C:\Program Files\Git\bin\sh.exe' --login

The --login switch makes the shell execute the login shell startup files.

Change the line endings in the view:

:e ++ff=dos
:e ++ff=mac
:e ++ff=unix

This can also be used as saving operation (:w alone will not save using the line endings you see on screen):

:w ++ff=dos
:w ++ff=mac
:w ++ff=unix

And you can use it from the command-line:

for file in *.cpp
do 
    vi +':w ++ff=unix' +':q' "$file"
done

You can just try

$(document).ready(function() {
   $('body').find('#item').removeClass();
});

If you have to access to that element without class name, for example you have to add a new class name, you can do that:

$(document).ready(function() {
   $('body').find('#item').removeClass().addClass('class-name');
});

I use that function in my projet to remove and add class in a html builder. Good luck.

Be careful about the back Ticks (`)

A bit 'lazy' way to do this is to use startswith- it is easier to understand this rather regexps. However regexps might work faster, I haven't measured.

>>> papa = "papa is a good man"
>>> app = "app is important"
>>> strip_word = 'papa'
>>> papa[len(strip_word):] if papa.startswith(strip_word) else papa
' is a good man'
>>> app[len(strip_word):] if app.startswith(strip_word) else app
'app is important'

i use as following for over come this matter

edittext_style.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:thickness="0dp"
android:shape="rectangle">
<stroke android:width="1dp"
        android:color="#c8c8c8"/>
<corners android:radius="0dp" />

And applied as bellow

<EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="textPersonName"
            android:ems="10"
            android:id="@+id/editTextName"
            android:background="@drawable/edit_text_style"/>

try like this..

I think it's important to note here that onBlur() fires regardless.

This is a helpful thread but the only thing it doesn't clarify is that onBlur() will fire every single time.

onChange() will only fire when the value is changed.

In C# 8.0 you can get the last item with ^ operator full explanation

List<char> list = ...;
var value = list[^1]; 

// Gets translated to 
var value = list[list.Count - 1];

c is the new dictionary, and a is your original dictionary, {'z','w'} are the keys you want to remove from a

c = {key:a[key] for key in a.keys() - {'z', 'w'}}

Also check: https://www.safaribooksonline.com/library/view/python-cookbook-3rd/9781449357337/ch01.html

The other answers have one problem: they rely on the action you do and not on the link itself to decide whether to load it in Safari or in webview.

Now sometimes this is exactly what you want, which is fine; but some other times, especially if you have anchor links in your page, you want really to open only external links in Safari, and not internal ones. In that case you should check the URL.host property of your request.

I use that piece of code to check whether I have a hostname in the URL that is being parsed, or if it is embedded html:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    static NSString *regexp = @"^(([a-zA-Z]|[a-zA-Z][a-zA-Z0-9-]*[a-zA-Z0-9])[.])+([A-Za-z]|[A-Za-z][A-Za-z0-9-]*[A-Za-z0-9])$";
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regexp];

    if ([predicate evaluateWithObject:request.URL.host]) {
        [[UIApplication sharedApplication] openURL:request.URL];
        return NO; 
    } else {
        return YES; 
    }
}

You can of course adapt the regular expression to fit your needs.

id             
1  0   1      1
   1   1      2

   4   2      2
3  7   3      1
4  8   4      1

(Keep in mind that you might need to order/sort before, depending on your data)

EDIT: As mentioned by the questioner, use df.groupby('id').head(2).reset_index(drop=True) to remove the multindex and flatten the results.

>>> df.groupby('id').head(2).reset_index(drop=True)
    id  value
0   1      1
1   1      2
2   2      1
3   2      2
4   3      1
5   4      1

You can use this in your case, it will work fine.

Standard C++ has no notion of 'colors'. So what you are asking depends on the operating system.

For Windows, you can check out the SetConsoleTextAttribute function.

On *nix, you have to use the ANSI escape sequences.

Change your Ands to AndAlsos

A standard And will test both expressions. If comp.Container is Nothing, then the second expression will raise a NullReferenceException because you're accessing a property on a null object.

AndAlso will short-circuit the logical evaluation. If comp.Container is Nothing, then the 2nd expression will not be evaluated.

Declare a method in you activity class. Then copy and paste the code below.

private void OpenAppInPlayStore(){

    Uri uri = Uri.parse("market://details?id=" + this.getPackageName());
    Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
    // To count with Play market backstack, After pressing back button,
    // to taken back to our application, we need to add following flags to intent.
    goToMarket.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY |
            Intent.FLAG_ACTIVITY_NEW_DOCUMENT |
            Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
    try {
        startActivity(goToMarket);
    } catch (ActivityNotFoundException e) {
        startActivity(new Intent(Intent.ACTION_VIEW,
                Uri.parse("http://play.google.com/store/apps/details?id=" + this.getPackageName())));
    }

}

Now call this method from anywhere of your code.

Follow the image below from my practical project.

In .NET Core 2.0 the user already exists as part of the underlying inherited controller. Just use the User as you would normally or pass across to any repository code.

[Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme, Policy = "TENANT")]
[HttpGet("issue-type-selection"), Produces("application/json")]
public async Task<IActionResult> IssueTypeSelection()
{
    try
    {
        return new ObjectResult(await _item.IssueTypeSelection(User));
    }
    catch (ExceptionNotFound)
    {
        Response.StatusCode = (int)HttpStatusCode.BadRequest;
        return Json(new
        {
            error = "invalid_grant",
            error_description = "Item Not Found"
        });
    }

This probably means that python doesn't know where PyQt5 is located. To check, go into the interactive terminal and type:

import sys
print sys.path

What you probably need to do is add the directory that contains the PyQt5 module to your PYTHONPATH environment variable. If you use bash, here's how:

Type the following into your shell, and add it to the end of the file ~/.bashrc

export PYTHONPATH=/path/to/PyQt5/directory:$PYTHONPATH

where /path/to/PyQt5/directory is the path to the folder where the PyQt5 library is located.

Hardware

If a GPU device has, for example, 4 multiprocessing units, and they can run 768 threads each: then at a given moment no more than 4*768 threads will be really running in parallel (if you planned more threads, they will be waiting their turn).

Software

threads are organized in blocks. A block is executed by a multiprocessing unit. The threads of a block can be indentified (indexed) using 1Dimension(x), 2Dimensions (x,y) or 3Dim indexes (x,y,z) but in any case xyz <= 768 for our example (other restrictions apply to x,y,z, see the guide and your device capability).

Obviously, if you need more than those 4*768 threads you need more than 4 blocks. Blocks may be also indexed 1D, 2D or 3D. There is a queue of blocks waiting to enter the GPU (because, in our example, the GPU has 4 multiprocessors and only 4 blocks are being executed simultaneously).

Now a simple case: processing a 512x512 image

Suppose we want one thread to process one pixel (i,j).

We can use blocks of 64 threads each. Then we need 512*512/64 = 4096 blocks (so to have 512x512 threads = 4096*64)

It's common to organize (to make indexing the image easier) the threads in 2D blocks having blockDim = 8 x 8 (the 64 threads per block). I prefer to call it threadsPerBlock.

dim3 threadsPerBlock(8, 8);  // 64 threads

and 2D gridDim = 64 x 64 blocks (the 4096 blocks needed). I prefer to call it numBlocks.

dim3 numBlocks(imageWidth/threadsPerBlock.x,  /* for instance 512/8 = 64*/
              imageHeight/threadsPerBlock.y); 

The kernel is launched like this:

myKernel <<<numBlocks,threadsPerBlock>>>( /* params for the kernel function */ );       

Finally: there will be something like "a queue of 4096 blocks", where a block is waiting to be assigned one of the multiprocessors of the GPU to get its 64 threads executed.

In the kernel the pixel (i,j) to be processed by a thread is calculated this way:

uint i = (blockIdx.x * blockDim.x) + threadIdx.x;
uint j = (blockIdx.y * blockDim.y) + threadIdx.y;

Update: Unless you love resizing icons one by one, check out Schmoudi's answer. It's just a lot easier.

Icon sizes

Above image from Designing for iOS 9. They are the same for iOS 10.

How to Set the App Icon

Click Assets.xcassets in the Project navigator and then choose AppIcon.

This will give you an empty app icon set.

Now just drag the right sized image (in .png format) from Finder onto every blank in the app set. The app icon should be all set up now.

How to create the right sized images

The image at the very top tells the pixels sizes for for each point size that is required in iOS 9. However, even if I don't get this answer updated for future versions of iOS, you can still figure out the correct pixel sizes using the method below.

Look at how many points (pt) each blank on the empty image set is. If the image is 1x then the pixels are the same as the points. For 2x double the points and 3x triple the points. So, for example, in the first blank above (29pt 2x) you would need a 58x58 pixel image.

You can start with a 1024x1024 pixel image and then downsize it to the correct sizes. You can do it yourself or there are also websites and scripts for getting the right sizes. Do a search for "ios app icon generator" or something similar.

I don't think the names matter as long as you get the dimensions right, but the general naming convention is as follows:

Icon-29.png      // 29x29 pixels
[email protected]   // 58x58 pixels
[email protected]   // 87x87 pixels

Launch Image

Although you can use an image for the launch screen, consider using a launch screen storyboard file. This will conveniently resize for every size and orientation. Check out this SO answer or the following documentation for help with this.

The Xcode images in this post were created with Xcode 7.

Use the following code in order to show and hide the keyboard

//Declare a delegate, assign your textField to the delegate and then include these methods

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShow:) name:UIKeyboardDidShowNotification object:nil];
    return YES;
}


- (BOOL)textFieldShouldEndEditing:(UITextField *)textField {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHide:) name:UIKeyboardDidHideNotification object:nil];

    [self.view endEditing:YES];
    return YES;
}


- (void)keyboardDidShow:(NSNotification *)notification
{
    // Assign new frame to your view 
    [self.view setFrame:CGRectMake(0,-110,320,460)]; //here taken -110 for example i.e. your view will be scrolled to -110. change its value according to your requirement.

}

-(void)keyboardDidHide:(NSNotification *)notification
{
    [self.view setFrame:CGRectMake(0,0,320,460)];
}

Try this:

this.TextBox3.Text = String.Format("{0: MM.dd.yyyy}",DateTime.Now);

Just adding to this that in ES6 because of arrow functions you shouldn't need to do this because they capture the this value.

What you need is properly a service:

.factory('DataLayer', ['$http',

    function($http) {

        var factory = {};
        var locations;

        factory.getLocations = function(success) {
            if(locations){
                success(locations);
                return;
            }
            $http.get('locations/locations.json').success(function(data) {
                locations = data;
                success(locations);
            });
        };

        return factory;
    }
]);

The locations would be cached in the service which worked as singleton model. This is the right way to fetch data.

Use this service DataLayer in your controller and directive is ok as following:

appControllers.controller('dummyCtrl', function ($scope, DataLayer) {
    DataLayer.getLocations(function(data){
        $scope.locations = data;
    });
});

.directive('map', function(DataLayer) {
    return {
        restrict: 'E',
        replace: true,
        template: '<div></div>',
        link: function(scope, element, attrs) {

            DataLayer.getLocations(function(data) {
                angular.forEach(data, function(location, key){
                    //do something
                });
            });
        }
    };
});

I solved this with Access options.

Go to the Office Button --> Access Options --> Trust Center --> Trust Center Settings Button --> Message Bar

In the right hand pane I selected the radio button "Show the message bar in all applications when content has been blocked."

Closed Access, reopened the database and got the warning for blocked content again.

As almost noted in comments to @BoltClock's answer, in modern browsers, you can actually add some html markup to pseudo-elements using the (url()) in combination with svg's <foreignObject> element.

You can either specify an URL pointing to an actual svg file, or create it with a dataURI version (data:image/svg+xml; charset=utf8, + encodeURIComponent(yourSvgMarkup))

But note that it is mostly a hack and that there are a lot of limitations :

• You can not load any external resources from this markup (no CSS, no images, no media etc.).
• You can not execute script.
• Since this won't be part of the DOM, the only way to alter it, is to pass the markup as a dataURI, and edit this dataURI in document.styleSheets. for this part, DOMParser and XMLSerializer may help.
• While the same operation allows us to load url-encoded media in <img> tags, this won't work in pseudo-elements (at least as of today, I don't know if it is specified anywhere that it shouldn't, so it may be a not-yet implemented feature).

Now, a small demo of some html markup in a pseudo element :

/* _x000D_
**  original svg code :_x000D_
*_x000D_
*<svg width="200" height="60"_x000D_

For sorted arrays (linear search)

All answers so far concentrate on searching through the whole array. Considering your array is sorted already and you really only want the nearest number this is probably the fastest solution:

var a = [2, 42, 82, 122, 162, 202, 242, 282, 322, 362];_x000D_
var target = 90000;_x000D_
_x000D_
/**_x000D_
 * Returns the closest number from a sorted array._x000D_
 **/_x000D_
function closest(arr, target) {_x000D_
  if (!(arr) || arr.length == 0)_x000D_
    return null;_x000D_
  if (arr.length == 1)_x000D_
    return arr[0];_x000D_
_x000D_
  for (var i = 1; i < arr.length; i++) {_x000D_
    // As soon as a number bigger than target is found, return the previous or current_x000D_
    // number depending on which has smaller difference to the target._x000D_
    if (arr[i] > target) {_x000D_
      var p = arr[i - 1];_x000D_
      var c = arr[i]_x000D_
      return Math.abs(p - target) < Math.abs(c - target) ? p : c;_x000D_
    }_x000D_
  }_x000D_
  // No number in array is bigger so return the last._x000D_
  return arr[arr.length - 1];_x000D_
}_x000D_
_x000D_
// Trying it out_x000D_
console.log(closest(a, target));

Note that the algorithm can be vastly improved e.g. using a binary tree.

I found a solution to this. It's bloody witchcraft, but it works.

When you install the client, open Control Panel > Network Connections.

You'll see a disabled network connection that was added by the TAP installer (Local Area Connection 3 or some such).

Right Click it, click Enable.

The device will not reset itself to enabled, but that's ok; try connecting w/ the client again. It'll work.

UPDATE: That a reboot helped was coincidental (I hoped so, hooray!). The real cause of the problem was this: When Gradle is directed to use a specific keystore, that keystore must also contain all the official root certificates. Otherwise it cannot access libraries from regular repositories. What I had to do was this:

Import the self-signed certificate:

keytool -import -trustcacerts -alias myselfsignedcert -file /Users/me/Desktop/selfsignedcert.crt -keystore ./privateKeystore.jks

Add the official root certificates:

keytool -importkeystore -srckeystore <java-home>/lib/security/cacerts -destkeystore ./privateKeystore.jks

Maybe the Gradle daemon also got in the way. Might be worth killing all running daemons found with ./gradlew --status if things start looking bleak.

ORIGINAL POSTING:

Nobody will believe this, I know. Still, if all else fails, give it a try: After a reboot of my Mac the problem was gone. Grrr.

Background: ./gradlew jar kept giving me "unable to find valid certification path to requested target"

I am stuck with a self-signed certificate, saved from browser, imported in privateKeystore.jks. Then instructed Gradle to work with privateKeystore.jks:

org.gradle.jvmargs=-Djavax.net.debug=SSL -Djavax.net.ssl.trustStore="/Users/me/IntelliJ/myproject/privateKeystore.jks"  -Djavax.net.ssl.trustStorePassword=changeit

As mentioned, this only worked after a reboot.

Andrey Tarasevich provides the following explanation:

1. On Google Groups
2. On bytes.com

[Minor changes to formatting made. Parenthetical annotations added in square brackets []].

The whole idea of using 'do/while' version is to make a macro which will expand into a regular statement, not into a compound statement. This is done in order to make the use of function-style macros uniform with the use of ordinary functions in all contexts.

Consider the following code sketch:

if (<condition>)
  foo(a);
else
  bar(a);

where foo and bar are ordinary functions. Now imagine that you'd like to replace function foo with a macro of the above nature [named CALL_FUNCS]:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

Now, if your macro is defined in accordance with the second approach (just { and }) the code will no longer compile, because the 'true' branch of if is now represented by a compound statement. And when you put a ; after this compound statement, you finished the whole if statement, thus orphaning the else branch (hence the compilation error).

One way to correct this problem is to remember not to put ; after macro "invocations":

if (<condition>)
  CALL_FUNCS(a)
else
  bar(a);

This will compile and work as expected, but this is not uniform. The more elegant solution is to make sure that macro expand into a regular statement, not into a compound one. One way to achieve that is to define the macro as follows:

#define CALL_FUNCS(x) \
do { \
  func1(x); \
  func2(x); \
  func3(x); \
} while (0)

Now this code:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

will compile without any problems.

However, note the small but important difference between my definition of CALL_FUNCS and the first version in your message. I didn't put a ; after } while (0). Putting a ; at the end of that definition would immediately defeat the entire point of using 'do/while' and make that macro pretty much equivalent to the compound-statement version.

I don't know why the author of the code you quoted in your original message put this ; after while (0). In this form both variants are equivalent. The whole idea behind using 'do/while' version is not to include this final ; into the macro (for the reasons that I explained above).

 * The cost to add or delete an element into a known location in the list 
   (i.e. if you have an iterator to the location) is O(1). If you don't 
   know the location, then you need to traverse the list to the location
   of deletion/insertion, which takes O(n) time. 

** The deletion cost is O(log n) for the minimum or maximum, O(n) for an
   arbitrary element.

It's not as easy as it seems to implement a control like that. Explorer works with shell items, not filesystem items (ex: the control panel, the printers folder, and so on). If you need to implement it i suggest to have a look at the Windows shell functions at http://msdn.microsoft.com/en-us/library/bb776426(VS.85).aspx.

Most likely your query failed, and the query call returned a boolean FALSE (or an error object of some sort), which you then try to use as if was a resultset object, causing the error. Try something like var_dump($result) to see what you really got.

Check for errors after EVERY database query call. Even if the query itself is syntactically valid, there's far too many reasons for it to fail anyways - checking for errors every time will save you a lot of grief at some point.

service.ClientCridentials.UserName.Password = "testPass";

In this way you can pass username, password in the header to a SOAP WCF Service.

I used to have the same problem finding a good library to do that. Eventually, I created a library which can do that: SwipeRevealLayout

In gradle file:

dependencies {
    compile 'com.chauthai.swipereveallayout:swipe-reveal-layout:1.4.0'
}

In your xml file:

<com.chauthai.swipereveallayout.SwipeRevealLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:mode="same_level"
    app:dragEdge="left">

    <!-- Your secondary layout here -->
    <FrameLayout
        android:layout_width="wrap_content"
        android:layout_height="match_parent" />

    <!-- Your main layout here -->
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</com.chauthai.swipereveallayout.SwipeRevealLayout>

Then in your adapter file:

public class Adapter extends RecyclerView.Adapter {
  // This object helps you save/restore the open/close state of each view
  private final ViewBinderHelper viewBinderHelper = new ViewBinderHelper();

  @Override
  public void onBindViewHolder(ViewHolder holder, int position) {
    // get your data object first.
    YourDataObject dataObject = mDataSet.get(position); 

    // Save/restore the open/close state.
    // You need to provide a String id which uniquely defines the data object.
    viewBinderHelper.bind(holder.swipeRevealLayout, dataObject.getId()); 

    // do your regular binding stuff here
  }
}

Delete any or specific file type(for example ".bak") from a path. See demo code below -

class Program
        {
        static void Main(string[] args)
            {

            // Specify the starting folder on the command line, or in 
            TraverseTree(ConfigurationManager.AppSettings["folderPath"]);

            // Specify the starting folder on the command line, or in 
            // Visual Studio in the Project > Properties > Debug pane.
            //TraverseTree(args[0]);

            Console.WriteLine("Press any key");
            Console.ReadKey();
            }

        public static void TraverseTree(string root)
            {

            if (string.IsNullOrWhiteSpace(root))
                return;

            // Data structure to hold names of subfolders to be
            // examined for files.
            Stack<string> dirs = new Stack<string>(20);

            if (!System.IO.Directory.Exists(root))
                {
                return;
                }

            dirs.Push(root);

            while (dirs.Count > 0)
                {
                string currentDir = dirs.Pop();

I just saw this blog entry: Money vs. Decimal in SQL Server.

Which basically says that money has a precision issue...

declare @m money
declare @d decimal(9,2)

set @m = 19.34
set @d = 19.34

select (@m/1000)*1000
select (@d/1000)*1000

For the money type, you will get 19.30 instead of 19.34. I am not sure if there is an application scenario that divides money into 1000 parts for calculation, but this example does expose some limitations.

When I did sudo /etc/init.d/php-fpm start I got the following error:

Starting php-fpm: [28-Mar-2013 16:18:16] ERROR: [pool www] cannot get uid for user 'apache'

I guess /etc/php-fpm.d/www.conf needs to know the user that the webserver is running as and assumes it's apache when, for nginx, it's actually nginx, and needs to be changed.

" In computer networking, a network host, Internet host, host, or Internet node is a computer connected to the Internet - or more generically - to any type of data network. A network host can host information resources as well as application software for providing network services. "-Wikipedia

Local host is a special name given to the local machine or that you are working on, ussually its IP Address is 127.0.0.1. However you can define it to be anything.

There are multiple Network services running on each host for example Apache/IIS( Http Web Server),Mail Clients, FTP clients etc. Each service has a specific port associated with it. You can think of it as this.

In every home, there is one mailbox and multiple people. The mailbox is a host. Your own home mailbox is a localhost. Each person in a home has a room. All letters for that person are sent to his room, hence the room number is a port.

Hope am not too late to the party, The easiest would be to edit the admin.py file.

admin.site.site_header = 'your_header'
admin.site.site_title = 'site_title'
admin.site.index_title = 'index_title'

You can't, you'll have to do something like

<script type="text/javascript">
   var php_var = "<?php echo $php_var; ?>";
</script>

You can also load it with AJAX

rhino is right, the snippet lacks of a type for the sake of brevity.

Also, note that if $php_var has quotes, it will break your script. You shall use addslashes, htmlentities or a custom function.

composer create-project laravel/laravel ProjectName 

Simple change to syntax is all that is needed:

 create table ImagenesUsuario (
   idImagen int not null identity(1,1) primary key
 )

By explicitly using the "constraint" keyword, you can give the primary key constraint a particular name rather than depending on SQL Server to auto-assign a name:

 create table ImagenesUsuario (
   idImagen int not null identity(1,1) constraint pk_ImagenesUsario primary key
 )

Add the "CLUSTERED" keyword if that makes the most sense based on your use of the table (i.e., the balance of searches for a particular idImagen and amount of writing outweighs the benefits of clustering the table by some other index).

Like the other posters have suggested, it sounds like you have a lock contention issue. We faced a similar issue a few weeks back; however, ours was much more intermittent, and often cleared up before we could get a DBA onto the server to run sp_who2 to trace down the issue.

What we ended up doing was implement an e-mail notification if a lock exceeded a certain threshold. Once we put this in place, we were able to identify the processes that were locking, and change the isolation level to read uncommitted where appropriate to fix the issue.

Here's an article that provides an overview of how to configure this type of notification.

If locking turns out to be the issue, and if you're not already doing so, I would suggest looking into configuring row versioning-based isolation levels.

If all else fails go to task manager and kill the msbuild task under Visual Studio 2017

Easiest way:

byte[] buffer;
using (Stream stream = new IO.FileStream("file.pdf"))
{
   buffer = new byte[stream.Length - 1];
   stream.Read(buffer, 0, buffer.Length);
}

using (Stream stream = new IO.FileStream("newFile.pdf"))
{
   stream.Write(buffer, 0, buffer.Length);
}

Or something along these lines...

Click on your project properties, go to the web section, from the Servers section, change from IIS express to Local IIS, it will create a virtual directory for you

I found this code where date is compared in a format to compare with date field in database...may be this might be helpful to you...

When you convert the string to date using simpledateformat, it is hard to compare with the Date field in mysql databases.

So convert the java string date in the format using select STR_to_DATE('yourdate','%m/%d/%Y') --> in this format, then you will get the exact date format of mysql date field.

The Columns collection is only populated when AutoGenerateColumns=false, and you manually generate the columns yourself.

A nice work-around for this is to dynamically populate the Columns collection yourself, before setting the DataSource property and calling DataBind().

I have a function that manually adds the columns based on the contents of the DataTable that I want to display. Once I have done that (and then set the DataSource and called DataBind(), I can use the Columns collection and the Count value is correct, and I can turn the column visibility on and off as I initially wanted to.

static void AddColumnsToGridView(GridView gv, DataTable table)
{
    foreach (DataColumn column in table.Columns)
    {
        BoundField field = new BoundField();
        field.DataField = column.ColumnName;
        field.HeaderText = column.ColumnName;
        gv.Columns.Add(field);
    }
}

GriffeyDog is definitely correct:

Code:

BigDecimal myBigDecimal = new BigDecimal("00000000.000000");
System.out.println("bestPriceBigDecimal=" + myBigDecimal);
System.out.println("BigDecimal.valueOf(0.000000)=" + BigDecimal.valueOf(0.000000));
System.out.println(" equals=" + myBigDecimal.equals(BigDecimal.ZERO));
System.out.println("compare=" + (0 == myBigDecimal.compareTo(BigDecimal.ZERO)));

Results:

myBigDecimal=0.000000
BigDecimal.valueOf(0.000000)=0.0
 equals=false
compare=true

While I understand the advantages of the BigDecimal compare, I would not consider it an intuitive construct (like the ==, <, >, <=, >= operators are). When you are holding a million things (ok, seven things) in your head, then anything you can reduce your cognitive load is a good thing. So I built some useful convenience functions:

public static boolean equalsZero(BigDecimal x) {
    return (0 == x.compareTo(BigDecimal.ZERO));
}
public static boolean equals(BigDecimal x, BigDecimal y) {
    return (0 == x.compareTo(y));
}
public static boolean lessThan(BigDecimal x, BigDecimal y) {
    return (-1 == x.compareTo(y));
}
public static boolean lessThanOrEquals(BigDecimal x, BigDecimal y) {
    return (x.compareTo(y) <= 0);
}
public static boolean greaterThan(BigDecimal x, BigDecimal y) {
    return (1 == x.compareTo(y));
}
public static boolean greaterThanOrEquals(BigDecimal x, BigDecimal y) {
    return (x.compareTo(y) >= 0);
}

Here is how to use them:

    System.out.println("Starting main Utils");
    BigDecimal bigDecimal0 = new BigDecimal(00000.00);
    BigDecimal bigDecimal2 = new BigDecimal(2);
    BigDecimal bigDecimal4 = new BigDecimal(4);  
    BigDecimal bigDecimal20 = new BigDecimal(2.000);
    System.out.println("Positive cases:");
    System.out.println("bigDecimal0=" + bigDecimal0 + " == zero is " + Utils.equalsZero(bigDecimal0));
    System.out.println("bigDecimal2=" + bigDecimal2 + " <  bigDecimal4=" + bigDecimal4 + " is " + Utils.lessThan(bigDecimal2, bigDecimal4));
    System.out.println("bigDecimal2=" + bigDecimal2 + " == bigDecimal20=" + bigDecimal20 + " is " + Utils.equals(bigDecimal2, bigDecimal20));
    System.out.println("bigDecimal2=" + bigDecimal2 + " <= bigDecimal20=" + bigDecimal20 + " is " + Utils.equals(bigDecimal2, bigDecimal20));
    System.out.println("bigDecimal2=" + bigDecimal2 + " <= bigDecimal4=" + bigDecimal4 + " is " + Utils.lessThanOrEquals(bigDecimal2, bigDecimal4));
    System.out.println("bigDecimal4=" + bigDecimal4 + " >  bigDecimal2=" + bigDecimal2 + " is " + Utils.greaterThan(bigDecimal4, bigDecimal2));
    System.out.println("bigDecimal4=" + bigDecimal4 + " >= bigDecimal2=" + bigDecimal2 + " is " + Utils.greaterThanOrEquals(bigDecimal4, bigDecimal2));
    System.out.println("bigDecimal2=" + bigDecimal2 + " >= bigDecimal20=" + bigDecimal20 + " is " + Utils.greaterThanOrEquals(bigDecimal2, bigDecimal20));
    System.out.println("Negative cases:");
    System.out.println("bigDecimal2=" + bigDecimal2 + " == zero is " + Utils.equalsZero(bigDecimal2));
    System.out.println("bigDecimal2=" + bigDecimal2 + " == bigDecimal4=" + bigDecimal4 + " is " + Utils.equals(bigDecimal2, bigDecimal4));
    System.out.println("bigDecimal4=" + bigDecimal4 + " <  bigDecimal2=" + bigDecimal2 + " is " + Utils.lessThan(bigDecimal4, bigDecimal2));
    System.out.println("bigDecimal4=" + bigDecimal4 + " <= bigDecimal2=" + bigDecimal2 + " is " + Utils.lessThanOrEquals(bigDecimal4, bigDecimal2));
    System.out.println("bigDecimal2=" + bigDecimal2 + " >  bigDecimal4=" + bigDecimal4 + " is " + Utils.greaterThan(bigDecimal2, bigDecimal4));
    System.out.println("bigDecimal2=" + bigDecimal2 + " >= bigDecimal4=" + bigDecimal4 + " is " + Utils.greaterThanOrEquals(bigDecimal2, bigDecimal4));

The results look like this:

Positive cases:
bigDecimal0=0 == zero is true
bigDecimal2=2 <  bigDecimal4=4 is true
bigDecimal2=2 == bigDecimal20=2 is true
bigDecimal2=2 <= bigDecimal20=2 is true
bigDecimal2=2 <= bigDecimal4=4 is true
bigDecimal4=4 >  bigDecimal2=2 is true
bigDecimal4=4 >= bigDecimal2=2 is true
bigDecimal2=2 >= bigDecimal20=2 is true
Negative cases:
bigDecimal2=2 == zero is false
bigDecimal2=2 == bigDecimal4=4 is false
bigDecimal4=4 <  bigDecimal2=2 is false
bigDecimal4=4 <= bigDecimal2=2 is false
bigDecimal2=2 >  bigDecimal4=4 is false
bigDecimal2=2 >= bigDecimal4=4 is false

Here is one solution using java 8:

Stream.of(list1, list2)
    .flatMap(Collection::stream)
    .distinct()
    // .sorted() uncomment if you want sorted list
    .collect(Collectors.toList());

For me the problem was very strange.
I have a testng.xml file at the root of my Eclipse project. When I changed the file through Eclipse, it wasn't changing the testng.xml file in my directory.

Turns out it made a copy of the folder into the eclipse workspace..

Hope this helps someone out

I would really recommend that you go through a tutorial like Sun's Java Concurrency before you commence in the magical world of multithreading.

There are also a number of good books out (google for "Concurrent Programming in Java", "Java Concurrency in Practice".

To get to your answer:

In your code that must wait for the dbThread, you must have something like this:

//do some work
synchronized(objectYouNeedToLockOn){
    while (!dbThread.isReady()){
        objectYouNeedToLockOn.wait();
    }
}
//continue with work after dbThread is ready

In your dbThread's method, you would need to do something like this:

//do db work
synchronized(objectYouNeedToLockOn){
    //set ready flag to true (so isReady returns true)
    ready = true;
    objectYouNeedToLockOn.notifyAll();
}
//end thread run method here

The objectYouNeedToLockOn I'm using in these examples is preferably the object that you need to manipulate concurrently from each thread, or you could create a separate Object for that purpose (I would not recommend making the methods themselves synchronized):

private final Object lock = new Object();
//now use lock in your synchronized blocks

To further your understanding:
There are other (sometimes better) ways to do the above, e.g. with CountdownLatches, etc. Since Java 5 there are a lot of nifty concurrency classes in the java.util.concurrent package and sub-packages. You really need to find material online to get to know concurrency, or get a good book.

In general, an alternative to case when ... is coalesce(nullif(x,bad_value),y) (that cannot be used in OP's case). For example,

select coalesce(nullif(y,''),x), coalesce(nullif(x,''),y), *
from (     (select 'abc' as x, '' as y)
 union all (select 'def' as x, 'ghi' as y)
 union all (select '' as x, 'jkl' as y)
 union all (select null as x, 'mno' as y)
 union all (select 'pqr' as x, null as y)
) q

gives:

 coalesce | coalesce |  x  |  y  
----------+----------+-----+-----
 abc      | abc      | abc | 
 ghi      | def      | def | ghi
 jkl      | jkl      |     | jkl
 mno      | mno      |     | mno
 pqr      | pqr      | pqr | 
(5 rows)

No, it sets all members/elements that haven't been explicitly set to their default-initialisation value, which is zero for numeric types.

What's log_b(n)?

It is the number of times you can cut a log of length n repeatedly into b equal parts before reaching a section of size 1.

To create a table on the fly us this syntax:

SELECT *
INTO A
FROM dbo.myView

It requires a bit of rearranging, but when does a good job to replace conditionals above. Here's the example from above written using the declarative syntax. Note that test3 stage is now two different stages. One that runs on the master branch and one that runs on anything else.

stage ('Test 3: Master') {
    when { branch 'master' }
    steps { 
        echo 'I only execute on the master branch.' 
    }
}

stage ('Test 3: Dev') {
    when { not { branch 'master' } }
    steps {
        echo 'I execute on non-master branches.'
    }
}

I'm assuming you're using express, given the logs you have in your question. The key is to set the timeout property on server (the following sets the timeout to one second, use whatever value you want):

var server = app.listen(app.get('port'), function() {
  debug('Express server listening on port ' + server.address().port);
});
server.timeout = 1000;

If you're not using express and are only working with vanilla node, the principle is the same. The following will not return data:

var http = require('http');
var server = http.createServer(function (req, res) {
  setTimeout(function() {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello World\n');
  }, 200);
}).listen(1337, '127.0.0.1');

server.timeout = 20;
console.log('Server running at http://127.0.0.1:1337/');

Most of the answers are/were valid. The new JAVA API modification for Date handling made sure that some earlier ambiguity in java date handling is reduced.

You will get a deprecated message for similar calls.

new Date() // deprecated

The above call had the developer to assume that a new Date object will give the Date object with current timestamp. This behavior is not consistent across other Java API classes.

The new way of doing this is using the Calendar Instance.

new SimpleDateFormat("yyyy-MM-dd").format(Calendar.getInstance().getTime()

Here too the naming convention is not perfect but this is much organised. For a person like me who has a hard time mugging up things but would never forget something if it sounds/appears logical, this is a good approach.

This is more synonymous to real life

1. We get a Calendar object and we look for the time in it. ( you must be wondering no body gets time from a Calendar, that is why I said it is not perfect.But that is a different topic altogether)
2. Then we want the date in a simple Text format so we use a SimpleDateFormat utility class which helps us in formatting the Date from Step 1. I have used yyyy, MM ,dd as parameters in the format. Supported date format parameters

One more way to do this is using Joda time API

new DateTime().toString("yyyy-MM-dd")

or the much obvious

new DateTime(Calendar.getInstance().getTime()).toString("yyyy-MM-dd")

both will return the same result.

Just like you do for getting something from the CNode you also need to do for the ANode

XmlNodeList xnList = xml.SelectNodes("/Element[@*]");
foreach (XmlNode xn in xnList)
{
  XmlNode anode = xn.SelectSingleNode("ANode");
    if (anode!= null)
    {
        string id = anode["ID"].InnerText;
        string date = anode["Date"].InnerText;
        XmlNodeList CNodes = xn.SelectNodes("ANode/BNode/CNode");
        foreach (XmlNode node in CNodes)
        {
         XmlNode example = node.SelectSingleNode("Example");
         if (example != null)
         {
            string na = example["Name"].InnerText;
            string no = example["NO"].InnerText;
         }
        }
    }
}

Check FlatStyle property. Setting it to "System" makes the checkbox sunken in my environment.

SC DELETE "service name"

Run the command on cmd as Administrator otherwise you will get this error :-

openservice failed 5 access is denied

HostingEnvironment.MapPath
System.Web.Hosting.HostingEnvironment.MapPath(path);

Check if the first line of file is empty:

BufferedReader br = new BufferedReader(new FileReader("path_to_some_file"));     
if (br.readLine() == null) {
    System.out.println("No errors, and file empty");
}

None of these answers quite satisfied me. I wanted a cross-platform solution that gave me the day in the local timezone without using any external libraries.

This is what I came up with:

function localDay(time) {
  var minutesOffset = time.getTimezoneOffset()
  var millisecondsOffset = minutesOffset*60*1000
  var local = new Date(time - millisecondsOffset)
  return local.toISOString().substr(0, 10)
}

That should return the day of the date, in YYYY-MM-DD format, in the timezone the date references.

So for example, localDay(new Date("2017-08-24T03:29:22.099Z")) will return "2017-08-23" even though it's already the 24th at UTC.

You'll need to polyfill Date.prototype.toISOString for it to work in Internet Explorer 8, but it should be supported everywhere else.

foreach((array)$items as $item) {}

int integer = 60;
byte[] bytes = new byte[4];
for (int i = 0; i < 4; i++) {
    bytes[i] = (byte)(integer >>> (i * 8));
}

^\d{1,2}[\W_]?po$

\d defines a number and {1,2} means 1 or two of the expression before, \W defines a non word character.

Researching this topic myself and having read the answers I recommend using the path.py library since it provides a context manager for changing the current working directory.

You then have something like

import path
if path.Path('../lib').isdir():
    with path.Path('..'):
        import lib

Although, you might just omit the isdir statement.

Here I'll add print statements to make it easy to follow what's happening

import path
import pandas

print(path.Path.getcwd())
print(path.Path('../lib').isdir())
if path.Path('../lib').isdir():
    with path.Path('..'):
        print(path.Path.getcwd())
        import lib
        print('Success!')
print(path.Path.getcwd())

which outputs in this example (where lib is at /home/jovyan/shared/notebooks/by-team/data-vis/demos/lib):

/home/jovyan/shared/notebooks/by-team/data-vis/demos/custom-chart
/home/jovyan/shared/notebooks/by-team/data-vis/demos
/home/jovyan/shared/notebooks/by-team/data-vis/demos/custom-chart

Since the solution uses a context manager, you are guaranteed to go back to your previous working directory, no matter what state your kernel was in before the cell and no matter what exceptions are thrown by importing your library code.

There is a Headers property in the HttpRequestMessage class. You can add custom headers there, which will be sent with each HTTP request. The DefaultRequestHeaders in the HttpClient class, on the other hand, sets headers to be sent with each request sent using that client object, hence the name Default Request Headers.

Hope this makes things more clear, at least for someone seeing this answer in future.

Convert handles DbNull sensibly.

employee.FirstName = Convert.ToString(sqlreader.GetValue(indexFirstName));

Both handlers get called.

You may be thinking of inline event binding (eg "onclick=..."), where a big drawback is only one handler may be set for an event.

jQuery conforms to the DOM Level 2 event registration model:

The DOM Event Model allows registration of multiple event listeners on a single EventTarget. To achieve this, event listeners are no longer stored as attribute values

I've encountered like this in Hybris.

1. Check your port in Resource Monitor > Network. Check if other service is using your port.

1.2 If yes, then you need to change your properties in project.properties

1.3 Change your address, any available address. In my case, I changed from 8000 to 8080. then save.

java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8080,suspend=n yourServer

2. In your console, rebuild your ant using command 'ant all'

3. Then debug again, using the command 'hybrisserver.bat debug'

Another way ( longer ) In VB.net [ Say 2300 Start and 0700 Finish next day ]

If tsStart > tsFinish Then

                            ' Take Hours difference and adjust accordingly
                            tsDifference = New TimeSpan((24 - tsStart.Hours) + tsFinish.Hours, 0, 0)

                            ' Add Minutes to Difference
                            tsDifference = tsDifference.Add(New TimeSpan(0, Math.Abs(tsStart.Minutes - tsFinish.Minutes), 0))


                            ' Add Seonds to Difference
                            tsDifference = tsDifference.Add(New TimeSpan(0, 0, Math.Abs(tsStart.Seconds - tsFinish.Seconds)))

Use parameter expansion, if the value is already stored in a variable.

$ str="GenFiltEff=7.092200e-01"
$ value=${str#*=}

Or use read

$ IFS="=" read name value <<< "GenFiltEff=7.092200e-01"

Either way,

$ echo $value
7.092200e-01

I use docker stats $(docker ps --format={{.Names}}) --no-stream to get :

5. Net I/O

using str.replace(regex, $1);:

}

Edit: adaptation regarding the comment

I think rake must be preinstalled if you want work with bundler. Try to install rake via 'gem install' and then run 'bundle install' again:

gem install rake && bundle install

If you are using rvm ( http://rvm.io ) rake is installed by default...

Building upon @B.M answer, here is a more general version and updated to work with newer library version: (numpy version 1.19.2, pandas version 1.2.1) And this solution can also deal with multi-indices:

However this is not heavily tested, use with caution.

If performance is important go down to numpy level:

import pandas as pd
import numpy as np

np.random.seed(0)
df = pd.DataFrame({'a': np.random.randint(0, 10, 90), 'b': [1,2,3]*30, 'c':list('abcefghij')*10, 'd': list('hij')*30})


def f_multi(df,col_names):
    if not isinstance(col_names,list):
        col_names = [col_names]
        
    values = df.sort_values(col_names).values.T

    col_idcs = [df.columns.get_loc(cn) for cn in col_names]
    other_col_names = [name for idx, name in enumerate(df.columns) if idx not in col_idcs]
    other_col_idcs = [df.columns.get_loc(cn) for cn in other_col_names]

    # split df into indexing colums(=keys) and data colums(=vals)
    keys = values[col_idcs,:]
    vals = values[other_col_idcs,:]
    
    # list of tuple of key pairs
    multikeys = list(zip(*keys))
    
    # remember unique key pairs and ther indices
    ukeys, index = np.unique(multikeys, return_index=True, axis=0)
    
    # split data columns according to those indices
    arrays = np.split(vals, index[1:], axis=1)

    # resulting list of subarrays has same number of subarrays as unique key pairs
    # each subarray has the following shape:
    #    rows = number of non-grouped data columns
    #    cols = number of data points grouped into that unique key pair
    
    # prepare multi index
    idx = pd.MultiIndex.from_arrays(ukeys.T, names=col_names) 

    list_agg_vals = dict()
    for tup in zip(*arrays, other_col_names):
        col_vals = tup[:-1] # first entries are the subarrays from above 
        col_name = tup[-1]  # last entry is data-column name
        
        list_agg_vals[col_name] = col_vals

    df2 = pd.DataFrame(data=list_agg_vals, index=idx)
    return df2

Tests:

In [227]: %timeit f_multi(df, ['a','d'])

2.54 ms ± 64.7 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

In [228]: %timeit df.groupby(['a','d']).agg(list)

4.56 ms ± 61.5 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Results:

for the random seed 0 one would get:

titleForHeaderInSection is a delegate method of UITableView so to apply header text of section write as follows,

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{

}

Are you trying to actually follow the link or trigger the onclick? You can trigger an onclick with something like this:

var link = document.getElementById(linkId);
link.onclick.call(link);

Over at Server Fault, a similar question was asked, and the solution there was:

choice /d y /t 5 > nul

Here's the version with Optional as a return value (cause you can't be sure the file has an extension)... also sanity checks...

import java.io.File;
import java.util.Optional;

public class GetFileExtensionTool {

    public static Optional<String> getFileExtension(File file) {
        if (file == null) {
            throw new NullPointerException("file argument was null");
        }
        if (!file.isFile()) {
            throw new IllegalArgumentException("getFileExtension(File file)"
                    + " called on File object that wasn't an actual file"
                    + " (perhaps a directory or device?). file had path: "
                    + file.getAbsolutePath());
        }
        String fileName = file.getName();
        int i = fileName.lastIndexOf('.');
        if (i > 0) {
            return Optional.of(fileName.substring(i + 1));
        } else {
            return Optional.empty();
        }
    }
}

Rewriting Git history demands changing all the affected commit ids, and so everyone who's working on the project will need to delete their old copies of the repo, and do a fresh clone after you've cleaned the history. The more people it inconveniences, the more you need a good reason to do it - your superfluous file isn't really causing a problem, but if only you are working on the project, you might as well clean up the Git history if you want to!

To make it as easy as possible, I'd recommend using the BFG Repo-Cleaner, a simpler, faster alternative to git-filter-branch specifically designed for removing files from Git history. One way in which it makes your life easier here is that it actually handles all refs by default (all tags, branches, etc) but it's also 10 - 50x faster.

You should carefully follow the steps here: http://rtyley.github.com/bfg-repo-cleaner/#usage - but the core bit is just this: download the BFG jar (requires Java 6 or above) and run this command:

$ java -jar bfg.jar --delete-files filename.orig my-repo.git

Your entire repository history will be scanned, and any file named filename.orig (that's not in your latest commit) will be removed. This is considerably easier than using git-filter-branch to do the same thing!

Full disclosure: I'm the author of the BFG Repo-Cleaner.

You can do this by using Instagram API ( User Endpoints: /users/search )

how-to in php :

function Request($url) {

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);  
    curl_setopt($ch, CURLOPT_HEADER, 0);  

    $result = curl_exec($ch);

    curl_close($ch);

    return $result;

}

function GetUserID($username, $access_token) {

    $url = "https://api.instagram.com/v1/users/search?q=" . $username . "&access_token=" . $access_token;

    if($result = json_decode(Request($url), true)) {

        return $result['data'][0]['id'];

    }

}

// example:
echo GetUserID('rathienth', $access_token);

Parsing pingtest.txt for each HOST name and result with batch is difficult because the name and result are on different lines.

It is much easier to test the result (the returned error code) of each PING command directly instead of redirecting to a file. It is also more efficient to enclose the entire construct in parens and redirect the final output just once.

>result.txt (
  for /f %%i in (testservers.txt) do ping -n 1 %%i >nul && echo %%i UP||echo %%i DOWN
)

The file /Applications/MAMP/bin/mamp/mamp.conf.json holds the MAMP configuration, look for the section:

{
  "name": "PHP",
  "version": "5.6.28, 7.0.20"
}

which lists the the php versions which will be displayed in the GUI, obviously you need to have downloaded the PHP version from the MAMP site first and placed it in /Applications/MAMP/bin/php for this to work.

import pygame, sys
from pygame.locals import *

def main():
    pygame.init()

    DISPLAY=pygame.display.set_mode((500,400),0,32)

    WHITE=(255,255,255)
    BLUE=(0,0,255)

    DISPLAY.fill(WHITE)

    pygame.draw.rect(DISPLAY,BLUE,(200,150,100,50))

    while True:
        for event in pygame.event.get():
            if event.type==QUIT:
                pygame.quit()
                sys.exit()
        pygame.display.update()

main()

This creates a simple window 500 pixels by 400 pixels that is white. Within the window will be a blue rectangle. You need to use the pygame.draw.rect to go about this, and you add the DISPLAY constant to add it to the screen, the variable blue to make it blue (blue is a tuple that values which equate to blue in the RGB values and it's coordinates.

Look up pygame.org for more info

You can do this:

create type number_tab is table of number;

select * from table (number_tab(1,2,3,4,5,6));

The column is given the name COLUMN_VALUE by Oracle, so this works too:

select column_value from table (number_tab(1,2,3,4,5,6));

If you want to show it as a full screen popup, then you don't even need an xml layout. Here's how do do it in Kotlin.

 val inputArray: Array<String> = arrayOf("Item 1","Item 2")
                val alt_bld =  AlertDialog.Builder(context);
                alt_bld.setTitle("Items:")
                alt_bld.setSingleChoiceItems(inputArray, -1) { dialog, which ->
                    if(which == 0){
                        //Item 1 Selected
                    }
                    else if(which == 1){
                        //Item 2 Selected
                    }
                    dialog.dismiss();

                }

                val alert11 = alt_bld.create()
                alert11.show()

to overcome this kind of problem follow the steps below:

• open command prompt.
• c:\Users\CGITS_04> netstat -o -n -a | findstr 0.0:80
• then you can see a list of process that is currently using port 80.
• open task manager->search the process-> select and end process.
• Now open eclipse and start tomcat.
• happy coding!

I would simply do this, which literally follows what your desired logic was:

df.groupby(['org']).mean().groupby(['cluster']).mean()

word-wrap: break-word

But it's CSS3 - http://www.css3.com/css-word-wrap/.

To summarize and a bit simplify, you can use:

-- 0 - 9
select floor(random() * 10);
-- 0 - 10
SELECT floor(random() * (10 + 1));
-- 1 - 10
SELECT ceil(random() * 10);

And you can test this like mentioned by @user80168

-- 0 - 9
SELECT min(i), max(i) FROM (SELECT floor(random() * 10) AS i FROM generate_series(0, 100000)) q;
-- 0 - 10
SELECT min(i), max(i) FROM (SELECT floor(random() * (10 + 1)) AS i FROM generate_series(0, 100000)) q;
-- 1 - 10
SELECT min(i), max(i) FROM (SELECT ceil(random() * 10) AS i FROM generate_series(0, 100000)) q;

If you want to use a string as a variable name, you can use assign:

var1="string_name"

assign(var1, c(5,4,5,6,7))

string_name 

[1] 5 4 5 6 7

The solutions above are great for interactive use, where you can eyeball the result and weed out false positives that way.

False positives can occur if the executable itself happens to match, or any arguments that are not script names match - the likelihood is greater with scripts that have no filename extensions.

Here's a more robust solution for scripting, using a shell function:

getscript() {
  pgrep -lf ".[ /]$1( |\$)"
}

Example use:

# List instance(s) of script "aa.sh" that are running.
getscript "aa.sh"  # -> (e.g.): 96112 bash /Users/jdoe/aa.sh

# Use in a test:
if getscript "aa.sh" >/dev/null; then
  echo RUNNING
fi

• Matching is case-sensitive (on macOS, you could add -i to the pgrep call to make it case-insensitive; on Linux, that is not an option.)
• The getscript function also works with full or partial paths that include the filename component; partial paths must not start with / and each component specified must be complete. The "fuller" the path specified, the lower the risk of false positives. Caveat: path matching will only work if the script was invoked with a path - this is generally true for scripts in the $PATH that are invoked directly.
• Even this function cannot rule out all false positives, as paths can have embedded spaces, yet neither ps nor pgrep reflect the original quoting applied to the command line. All the function guarantees is that any match is not the first token (which is the interpreter), and that it occurs as a separate word, optionally preceded by a path.
• Another approach to minimizing the risk of false positives could be to match the executable name (i.e., interpreter, such as bash) as well - assuming it is known; e.g.

# List instance(s) of a running *bash* script.
getbashscript() {
  pgrep -lf "(^|/)bash( | .*/)$1( |\$)"
}

If you're willing to make further assumptions - such as script-interpreter paths never containing embedded spaces - the regexes could be made more restrictive and thus further reduce the risk of false positives.

Below is the code that implements custom vertical scrollbar. The important detail here is to know when scrollbar is needed by calculating how much space is consumed by the controls that you add to the panel.

panelUserInput.SuspendLayout();
panelUserInput.Controls.Clear();
panelUserInput.AutoScroll = false;
panelUserInput.VerticalScroll.Visible = false;

// here you'd be adding controls

int x = 20, y = 20, height = 0;
for (int inx = 0; inx < numControls; inx++ )
{
    // this example uses textbox control
    TextBox txt = new TextBox();
    txt.Location = new System.Drawing.Point(x, y);
    // add whatever details you need for this control
    // before adding it to the panel
    panelUserInput.Controls.Add(txt);
    height = y + txt.Height;
    y += 25;
}
if (height > panelUserInput.Height)
{
    VScrollBar bar = new VScrollBar();
    bar.Dock = DockStyle.Right;
    bar.Scroll += (sender, e) => { panelUserInput.VerticalScroll.Value =  bar.Value; };
    bar.Top = 0;
    bar.Left = panelUserInput.Width - bar.Width;
    bar.Height = panelUserInput.Height;
    bar.Visible = true;
    panelUserInput.Controls.Add(bar);
}
panelUserInput.ResumeLayout();

// then update the form
this.PerformLayout();

You absolutely need to know where the files to be read can be located. However, this information can be relative of course so it may be well adapted to other systems.

So it could relate to the current directory (get it from Directory.GetCurrentDirectory()) or to the application executable path (eg. Application.ExecutablePath comes to mind if using Windows Forms or via Assembly.GetEntryAssembly().Location) or to some special Windows directory like "Documents and Settings" (you should use Environment.GetFolderPath() with one element of the Environment.SpecialFolder enumeration).

Note that the "current directory" and the path of the executable are not necessarily identical. You need to know where to look!

In either case, if you need to manipulate a path use the Path class to split or combine parts of the path.

We can mock list properly for foreach loop. Please find below code snippet and explanation.

This is my actual class method where I want to create test case by mocking list. this.nameList is a list object.

public void setOptions(){
    // ....
    for (String str : this.nameList) {
        str = "-"+str;
    }
    // ....
}

The foreach loop internally works on iterator, so here we crated mock of iterator. Mockito framework has facility to return pair of values on particular method call by using Mockito.when().thenReturn(), i.e. on hasNext() we pass 1st true and on second call false, so that our loop will continue only two times. On next() we just return actual return value.

@Test
public void testSetOptions(){
    // ...
    Iterator<SampleFilter> itr = Mockito.mock(Iterator.class);
    Mockito.when(itr.hasNext()).thenReturn(true, false);
    Mockito.when(itr.next()).thenReturn(Mockito.any(String.class);  

    List mockNameList = Mockito.mock(List.class);
    Mockito.when(mockNameList.iterator()).thenReturn(itr);
    // ...
}

In this way we can avoid sending actual list to test by using mock of list.

Try this:

ul li a:after {
    display: block;
    content: "";
    width: 3px;
    height: 5px;
    background: transparent url('../images/small_triangle.png') no-repeat;
}

You need the content: ""; declaration to give your generated element content, even if that content is "nothing".

Also, I fixed the syntax/ordering of your background declaration.

Warning: GCC can optimize away an overflow check when compiling with -O2. The option -Wall will give you a warning in some cases like

if (a + b < a) { /* Deal with overflow */ }

but not in this example:

b = abs(a);
if (b < 0) { /* Deal with overflow */ }

The only safe way is to check for overflow before it occurs, as described in the CERT paper, and this would be incredibly tedious to use systematically.

Compiling with -fwrapv solves the problem, but disables some optimizations.

We desperately need a better solution. I think the compiler should issue a warning by default when making an optimization that relies on overflow not occurring. The present situation allows the compiler to optimize away an overflow check, which is unacceptable in my opinion.

I wrote a function for the FFT in Java: http://www.wikijava.org/wiki/The_Fast_Fourier_Transform_in_Java_%28part_1%29

It's in the Public Domain so you can use those functions everywhere (personal or business projects too). Just cite me in the credits and send me just a link of your work, and you're ok.

It is completely reliable. I've checked its output against the Mathematica's FFT and they were always correct until the 15th decimal digit. I think it's a very good FFT implementation for Java. I wrote it on the J2SE 1.6 version, and tested it on the J2SE 1.5-1.6 version.

If you count the number of instruction (it's a lot much simpler than a perfect computational complexity function estimation) you can clearly see that this version is great even if it's not optimized at all. I'm planning to publish the optimized version if there are enough requests.

Let me know if it was useful, and tell me any comment you like.

For Bootstrap 4 Alpha 6

For Bootstrap 4 you have to use .hidden-xs-up.

https://v4-alpha.getbootstrap.com/layout/responsive-utilities/#available-classes

The .hidden-*-up classes hide the element when the viewport is at the given breakpoint or wider. For example, .hidden-md-up hides an element on medium, large, and extra-large viewports.

There is also hidden HTML5 attribute.

https://v4-alpha.getbootstrap.com/content/reboot/#html5-hidden-attribute

HTML5 adds a new global attribute named [hidden], which is styled as display: none by default. Borrowing an idea from PureCSS, we improve upon this default by making [hidden] { display: none !important; } to help prevent its display from getting accidentally overridden. While [hidden] isn’t natively supported by IE10, the explicit declaration in our CSS gets around that problem.

<input type="text" hidden>

There is also .invisible which does affect the layout.

https://v4-alpha.getbootstrap.com/utilities/invisible-content/

The .invisible class can be used to toggle only the visibility of an element, meaning its display is not modified and the element can still affect the flow of the document.

theharshest answered the question but here is another way to do the same thing. Also, In your example you have NAME in caps and in your code you have name in lowercase.

s = '<div class="question" id="get attrs" name="python" x="something">Hello World</div>'
soup = BeautifulSoup(s)

attributes_dictionary = soup.find('div').attrs
print attributes_dictionary
# prints: {'id': 'get attrs', 'x': 'something', 'class': ['question'], 'name': 'python'}

print attributes_dictionary['class'][0]
# prints: question

print soup.find('div').get_text()
# prints: Hello World

Use a QR library like ZXing... I had very good experience with it, QrDroid is much buggier. If you must rely on an external reader, rely on a standard one like Google Goggles!

You can also do this with positioning, set parent div to relative and child div to absolute.

.wrapper {
      position: relative;
  }
.childDiv {
      position: absolute;
      left: 50%;
      transform: translateX(-50%);
  }

Ok. So you said you understand the basics, but you're not sure EXACTLY how it works. First of all, this is a great answer to the Project Euler question it stems from. I've done a lot of research into this problem and this is by far the simplest response.

For the purpose of explanation, I'll let n = 20. To run the real Project Euler problem, let n = 600851475143.

n = 20 
i = 2

while i * i < n:
    while n%i == 0:
        n = n / i
    i = i + 1

print (n)

This explanation uses two while loops. The biggest thing to remember about while loops is that they run until they are no longer true.

The outer loop states that while i * i isn't greater than n (because the largest prime factor will never be larger than the square root of n), add 1 to i after the inner loop runs.

The inner loop states that while i divides evenly into n, replace n with n divided by i. This loop runs continuously until it is no longer true. For n=20 and i=2, n is replaced by 10, then again by 5. Because 2 doesn't evenly divide into 5, the loop stops with n=5 and the outer loop finishes, producing i+1=3.

Finally, because 3 squared is greater than 5, the outer loop is no longer true and prints the result of n.

Thanks for posting this. I looked at the code forever before realizing how exactly it worked. Hopefully, this is what you're looking for in a response. If not, let me know and I can explain further.

Here are some helper functions I use:

Array.contains = function (arr, key) {
    for (var i = arr.length; i--;) {
        if (arr[i] === key) return true;
    }
    return false;
};

Array.add = function (arr, key, value) {
    for (var i = arr.length; i--;) {
        if (arr[i] === key) return arr[key] = value;
    }
    this.push(key);
};

Array.remove = function (arr, key) {
    for (var i = arr.length; i--;) {
        if (arr[i] === key) return arr.splice(i, 1);
    }
};

Structs can have functions just like classes. The only difference is that they are public by default:

struct A {
    void f() {}
};

Additionally, structs can also have constructors and destructors.

struct A {
    A() : x(5) {}
    ~A() {}

    private: int x;
};

Before reading this answer, bear in mind that there is another answer below, from Roman Kh, which uses numpy.cumsum and is MUCH MUCH FASTER than this one.

Best One common way to apply a moving/sliding average (or any other sliding window function) to a signal is by using numpy.convolve().

def movingaverage(interval, window_size):
    window = numpy.ones(int(window_size))/float(window_size)
    return numpy.convolve(interval, window, 'same')

Here, interval is your x array, and window_size is the number of samples to consider. The window will be centered on each sample, so it takes samples before and after the current sample in order to calculate the average. Your code would become:

plot(x,y)
xlim(0,1000)

x_av = movingaverage(interval, r)
plot(x_av, y)

xlabel("Months since Jan 1749.")
ylabel("No. of Sun spots")
show()

Hope this helps!

TL;DR: Tell Chrome that this is a new password input and it won't provide old ones as autocomplete suggestions:

<input type="password" name="password" autocomplete="new-password">

autocomplete="off" doesn't work due to a design decision - lots of research shows that users have much longer and harder to hack passwords if they can store them in a browser or password manager.

The specification for autocomplete has changed, and now supports various values to make login forms easy to auto complete:

<!-- Auto fills with the username for the site, even though it's email format -->
<input type="email" name="email" autocomplete="username">

<!-- current-password will populate for the matched username input  -->
<input type="password" autocomplete="current-password" />

If you don't provide these Chrome still tries to guess, and when it does it ignores autocomplete="off".

The solution is that autocomplete values also exist for password reset forms:

<label>Enter your old password:
    <input type="password" autocomplete="current-password" name="pass-old" />
</label>
<label>Enter your new password:
    <input type="password" autocomplete="new-password" name="pass-new" />
</label>
<label>Please repeat it to be sure:
    <input type="password" autocomplete="new-password" name="pass-repeat" />
</label>

You can use this autocomplete="new-password" flag to tell Chrome not to guess the password, even if it has one stored for this site.

Chrome can also manage passwords for sites directly using the credentials API, which is a standard and will probably have universal support eventually.

It looks like the class.phpmailer.php file is corrupt. I would download the latest version and try again.

I've always used phpMailer's SMTP feature:

$mail->IsSMTP();
$mail->Host = "localhost";

And if you need debug info:

$mail->SMTPDebug  = 2; // enables SMTP debug information (for testing)
                       // 1 = errors and messages
                       // 2 = messages only

This is not to check for null, instead this will be helpful in converting an existing object to an empty object(fresh object). I dont know whether this is relevant or not, but I had such a requirement.

@SuppressWarnings({ "unchecked" })
static void emptyObject(Object obj) 
{
    Class c1 = obj.getClass();
    Field[] fields = c1.getDeclaredFields();

    for(Field field : fields)
    {
        try
        {
            if(field.getType().getCanonicalName() == "boolean")
            {
                field.set(obj, false);
            }
            else if(field.getType().getCanonicalName() == "char")
            {
                field.set(obj, '\u0000');
            }
            else if((field.getType().isPrimitive()))
            {
                field.set(obj, 0);
            }
            else
            {
                field.set(obj, null);
            }
        }
        catch(Exception ex)
        {

        }
    }
}

PHP has functions to help you with this:

$arrayToBeSorted = array('west', 'east', 'south', 'north');
$order = array('north', 'south', 'east', 'west');

// sort array
usort($arrayToBeSorted, function($a, $b) use ($order){
    // sort using the numeric index of the second array
    $valA = array_search($a, $order);
    $valB = array_search($b, $order);

    // move items that don't match to end
    if ($valA === false)
        return -1;
    if ($valB === false)
        return 0;

    if ($valA > $valB)
        return 1;
    if ($valA < $valB)
        return -1;
    return 0;
});

Usort does all the work for you and array_search provides the keys. array_search() returns false when it can't find a match so items that are not in the sort array naturally move to the bottom of the array.

Note: uasort() will order the array without affecting the key => value relationships.

iOS 9.0 and Later :

NSBatchDeleteRequest is used to delete records in core data. It works very fast and takes less time to delete all records from an entity. It requires NSFetchRequest in argument. If you want to delete all records from an entity, you can use it and it works for me.

let manageObject:NSManagedObjectContext = appDelegateObject.managedObjectContext

let fetchRequest = NSFetchRequest(entityName: “EnityName”)

let deleteRequest = NSBatchDeleteRequest(fetchRequest: fetchRequest)

let persistCor:NSPersistentStoreCoordinator = appDelegateObject.persistentObject
 do {
        try persistCor.executeRequest(deleteRequest, withContext: manageObject)
        try manageObject.save()
    } catch {
        print(error?.localizedDescription)
    }

Maybe just unbind the beforeunload event handler within the form's submit event handler:

jQuery('form').submit(function() {
    jQuery(window).unbind("beforeunload");
    ...
});

UPDATE table1 SET (col1, col2) = (col2, col3) FROM othertable WHERE othertable.col1 = 123;

Open up terminal first and then go to directory of web server

cd /Library/WebServer/Documents

and then type this and what you will do is you will give read and write permission

sudo chmod -R o+w /Library/WebServer/Documents

This will surely work!

A trick I use that works on more than just Mobile Safari is to use HTML escape codes and a little mark-up in the phone number. This makes it more difficult for the browser to "identify" a phone number, i.e.

Phone: 1-8&#48;&#48;<span>-</span>62&#48;<span>-</span>38&#48;3

Consider this approach, you don't need a for loop:

using (SqlBulkCopy bulkCopy = new SqlBulkCopy(connection))
{
    bulkCopy.DestinationTableName = 
        "dbo.BulkCopyDemoMatchingColumns";

    try
    {
        // Write from the source to the destination.
        bulkCopy.WriteToServer(ExitingSqlTableName);
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
}

Tapestry pages and components are simple POJO's(Plain Old Java Object) consisting of getters and setters for easy access to Java language features.

What Ed Guiness suggested is really a performance booster , I had a query like this

select * from table where id in (id1,id2.........long list)

what i did :

DECLARE @temp table(
            ID  int
            )
insert into @temp 
select * from dbo.fnSplitter('#idlist#')

Then inner joined the temp with main table :

select * from table inner join temp on temp.id = table.id

And performance improved drastically.

You can try c#

public string ProcessMyDataItem(object myValue)
 {
  if (myValue == null)
   {
   return "0 %"";
  }
   else
  {
     if(Convert.ToInt32(myValue) < 50)
       return "0";
     else
      return myValue.ToString() + "%";
  }

 }

asp

 <div class="tooltip" style="display: none">                                                                  
      <div style="text-align: center; font-weight: normal">
   Value =<%# ProcessMyDataItem(Eval("Percentage")) %> </div>
 </div>

When you click the Button

if(isset($_POST['save'])){
        $sql = "INSERT INTO `members`(`id`, `membership_id`, `email`, `first_name`)
        VALUES ('".$_POST["id"]."','".$_POST["membership_id"]."','".$_POST["email"]."','".$_POST["firstname"]."')";
    **if ($conn->query($sql) === TRUE) {
        echo "New record created successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }**
}

This will execute the Query in the variable $sql

    if ($conn->query($sql) === TRUE) {
        echo "New record created successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }

File.AppendAllText does not know about the stream you have opened, so will internally try to open the file again. Because your stream is blocking access to the file, File.AppendAllText will fail, throwing the exception you see.

I suggest you used str.Write or str.WriteLine instead, as you already do elsewhere in your code.

Your file is created but contains nothing because the exception is thrown before str.Flush() and str.Close() are called.

Lists of bytes are subscriptable (at least in Python 3.6). This way you can retrieve the decimal value of each byte individually.

>>> intlist = [64, 4, 26, 163, 255]
>>> bytelist = bytes(intlist)       # b'@x04\x1a\xa3\xff'

>>> for b in bytelist:
...    print(b)                     # 64  4  26  163  255

>>> [b for b in bytelist]           # [64, 4, 26, 163, 255]

>>> bytelist[2]                     # 26 

Just call fig.tight_layout() as you normally would. (pyplot is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)

There shouldn't be a difference between the QtAgg backend and the default backend (or if there is, it's a bug).

E.g.

import matplotlib.pyplot as plt

#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so 
#--    we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

plt.show()

Before Tight Layout

After Tight Layout

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

fig.tight_layout()

plt.show()

WebSockets is definitely the future.

Long polling is a dirty workaround to prevent creating connections for each request like AJAX does -- but long polling was created when WebSockets didn't exist. Now due to WebSockets, long polling is going away.

WebRTC allows for peer-to-peer communication.

I recommend learning WebSockets.

Comparison:

of different communication techniques on the web

• AJAX - request → response. Creates a connection to the server, sends request headers with optional data, gets a response from the server, and closes the connection. Supported in all major browsers.

• Long poll - request → wait → response. Creates a connection to the server like AJAX does, but maintains a keep-alive connection open for some time (not long though). During connection, the open client can receive data from the server. The client has to reconnect periodically after the connection is closed, due to timeouts or data eof. On server side it is still treated like an HTTP request, same as AJAX, except the answer on request will happen now or some time in the future, defined by the application logic. support chart (full) | wikipedia

• WebSockets - client ↔ server. Create a TCP connection to the server, and keep it open as long as needed. The server or client can easily close the connection. The client goes through an HTTP compatible handshake process. If it succeeds, then the server and client can exchange data in both directions at any time. It is efficient if the application requires frequent data exchange in both ways. WebSockets do have data framing that includes masking for each message sent from client to server, so data is simply encrypted. support chart (very good) | wikipedia

• WebRTC - peer ↔ peer. Transport to establish communication between clients and is transport-agnostic, so it can use UDP, TCP or even more abstract layers. This is generally used for high volume data transfer, such as video/audio streaming, where reliability is secondary and a few frames or reduction in quality progression can be sacrificed in favour of response time and, at least, some data transfer. Both sides (peers) can push data to each other independently. While it can be used totally independent from any centralised servers, it still requires some way of exchanging endPoints data, where in most cases developers still use centralised servers to "link" peers. This is required only to exchange essential data for establishing a connection, after which a centralised server is not required. support chart (medium) | wikipedia

• Server-Sent Events - client ← server. Client establishes persistent and long-term connection to server. Only the server can send data to a client. If the client wants to send data to the server, it would require the use of another technology/protocol to do so. This protocol is HTTP compatible and simple to implement in most server-side platforms. This is a preferable protocol to be used instead of Long Polling. support chart (good, except IE) | wikipedia

Advantages:

The main advantage of WebSockets server-side, is that it is not an HTTP request (after handshake), but a proper message based communication protocol. This enables you to achieve huge performance and architecture advantages. For example, in node.js, you can share the same memory for different socket connections, so they can each access shared variables. Therefore, you don't need to use a database as an exchange point in the middle (like with AJAX or Long Polling with a language like PHP). You can store data in RAM, or even republish between sockets straight away.

Security considerations

People are often concerned about the security of WebSockets. The reality is that it makes little difference or even puts WebSockets as better option. First of all, with AJAX, there is a higher chance of MITM, as each request is a new TCP connection that is traversing through internet infrastructure. With WebSockets, once it's connected it is far more challenging to intercept in between, with additionally enforced frame masking when data is streamed from client to server as well as additional compression, which requires more effort to probe data. All modern protocols support both: HTTP and HTTPS (encrypted).

P.S.

Remember that WebSockets generally have a very different approach of logic for networking, more like real-time games had all this time, and not like http.

In TorpedoQuery it look like this

Entity from = from(Entity.class);
where(from.getCode()).in("Joe", "Bob");
Query<Entity> select = select(from);

In C#, per MSDN library, we have the "const" keyword that does the work of the "#define" keyword in other languages.

"...when the compiler encounters a constant identifier in C# source code (for example, months), it substitutes the literal value directly into the intermediate language (IL) code that it produces." ( https://msdn.microsoft.com/en-us/library/ms173119.aspx )

Initialize constants at time of declaration since there is no changing them.

public const int cMonths = 12;

public void goToLocationFromAddress(String strAddress) {
    //Create coder with Activity context - this
    Geocoder coder = new Geocoder(this);
    List<Address> address;

    try {
        //Get latLng from String
        address = coder.getFromLocationName(strAddress, 5);

        //check for null
        if (address != null) {

            //Lets take first possibility from the all possibilities.
            try {
                Address location = address.get(0);
                LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());

                //Animate and Zoon on that map location
                mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
                mMap.animateCamera(CameraUpdateFactory.zoomTo(15));
            } catch (IndexOutOfBoundsException er) {
                Toast.makeText(this, "Location isn't available", Toast.LENGTH_SHORT).show();
            }

        }


    } catch (IOException e) {
        e.printStackTrace();
    }
}

It's pretty simple. Pay attention and you'll get it right away! :)

You will create a html array, which will be then sent to php array. Your html code will look like this:

<input type="checkbox" name="check_list[1]" alt="Checkbox" value="checked">
<input type="checkbox" name="check_list[2]" alt="Checkbox" value="checked">
<input type="checkbox" name="check_list[3]" alt="Checkbox" value="checked">

Where [1] [2] [3] are the IDs of your messages, meaning that you will echo your $row['Report ID'] in their place.

Then, when you submit the form, your PHP array will look like this:

print_r($check_list)

[1] => checked [3] => checked

Depending on which were checked and which were not.

I'm sure you can continue from this point forward.

In Python, curly braces are used to define a dictionary.

a={'one':1, 'two':2, 'three':3}
a['one']=1
a['three']=3

In other languages, { } are used as part of the flow control. Python however used indentation as its flow control because of its focus on readable code.

for entry in entries:

There's a little easter egg in Python when it comes to braces. Try running this on the Python Shell and enjoy.

Its very late here but thought to share below code. If we have our WebApi as a different project altogether in the same solution then we can call the same from MVC controller like below

public class ProductsController : Controller
    {
        // GET: Products
        public async Task<ActionResult> Index()
        {
            string apiUrl = "http://localhost:58764/api/values";

            using (HttpClient client=new HttpClient())
            {
                client.BaseAddress = new Uri(apiUrl);
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

                HttpResponseMessage response = await client.GetAsync(apiUrl);
                if (response.IsSuccessStatusCode)
                {
                    var data = await response.Content.ReadAsStringAsync();
                    var table = Newtonsoft.Json.JsonConvert.DeserializeObject<System.Data.DataTable>(data);

                }


            }
            return View();

        }
    }

I had the same issue. This is my solution using angular documentation and firebase Token:

getService()  {

const accessToken=this.afAuth.auth.currentUser.getToken().then(res=>{
  const httpOptions = {
    headers: new HttpHeaders({
      'Content-Type':  'application/json',
      'Authorization': res
    })
  };
  return this.http.get('Url',httpOptions)
    .subscribe(res => console.log(res));
}); }}

When the UI component that registers the BR is destroyed, so is the BR. Therefore when the code gets to unregistering, the BR may have already been destroyed.

Docker isn't virtualization, as such -- instead, it's an abstraction on top of the kernel's support for different process namespaces, device namespaces, etc.; one namespace isn't inherently more expensive or inefficient than another, so what actually makes Docker have a performance impact is a matter of what's actually in those namespaces.

Docker's choices in terms of how it configures namespaces for its containers have costs, but those costs are all directly associated with benefits -- you can give them up, but in doing so you also give up the associated benefit:

• Layered filesystems are expensive -- exactly what the costs are vary with each one (and Docker supports multiple backends), and with your usage patterns (merging multiple large directories, or merging a very deep set of filesystems will be particularly expensive), but they're not free. On the other hand, a great deal of Docker's functionality -- being able to build guests off other guests in a copy-on-write manner, and getting the storage advantages implicit in same -- ride on paying this cost.
• DNAT gets expensive at scale -- but gives you the benefit of being able to configure your guest's networking independently of your host's and have a convenient interface for forwarding only the ports you want between them. You can replace this with a bridge to a physical interface, but again, lose the benefit.
• Being able to run each software stack with its dependencies installed in the most convenient manner -- independent of the host's distro, libc, and other library versions -- is a great benefit, but needing to load shared libraries more than once (when their versions differ) has the cost you'd expect.

And so forth. How much these costs actually impact you in your environment -- with your network access patterns, your memory constraints, etc -- is an item for which it's difficult to provide a generic answer.
