For a API v3 solution, refer to:

http://blog.enbake.com/draw-circle-with-google-maps-api-v3

It creates circle around points and then show markers within and out of the range with different colors. They also calculate dynamic radius but in your case radius is fixed so may be less work.

Very old question, but just had to build this for an app today and found the settings shown in other answers do not result in a clean image (possibly as new options were added in later .Net versions).

Assuming you want the text in the centre of the bitmap, you can do this:

// Load the original image
Bitmap bmp = new Bitmap("filename.bmp");

// Create a rectangle for the entire bitmap
RectangleF rectf = new RectangleF(0, 0, bmp.Width, bmp.Height);

// Create graphic object that will draw onto the bitmap
Graphics g = Graphics.FromImage(bmp);

// ------------------------------------------
// Ensure the best possible quality rendering
// ------------------------------------------
// The smoothing mode specifies whether lines, curves, and the edges of filled areas use smoothing (also called antialiasing). 
// One exception is that path gradient brushes do not obey the smoothing mode. 
// Areas filled using a PathGradientBrush are rendered the same way (aliased) regardless of the SmoothingMode property.
g.SmoothingMode = SmoothingMode.AntiAlias;

// The interpolation mode determines how intermediate values between two endpoints are calculated.
g.InterpolationMode = InterpolationMode.HighQualityBicubic;

// Use this property to specify either higher quality, slower rendering, or lower quality, faster rendering of the contents of this Graphics object.
g.PixelOffsetMode = PixelOffsetMode.HighQuality;

// This one is important
g.TextRenderingHint = TextRenderingHint.AntiAliasGridFit;

// Create string formatting options (used for alignment)
StringFormat format = new StringFormat()
{
    Alignment = StringAlignment.Center,
    LineAlignment = StringAlignment.Center
};

// Draw the text onto the image
g.DrawString("yourText", new Font("Tahoma",8), Brushes.Black, rectf, format);

// Flush all graphics changes to the bitmap
g.Flush();

// Now save or use the bitmap
image.Image = bmp;

You should use DrawEllipse:

//
// Summary:
//     Draws an ellipse defined by a bounding rectangle specified by coordinates
//     for the upper-left corner of the rectangle, a height, and a width.
//
// Parameters:
//   pen:
//     System.Drawing.Pen that determines the color, width,
//      and style of the ellipse.
//
//   x:
//     The x-coordinate of the upper-left corner of the bounding rectangle that
//     defines the ellipse.
//
//   y:
//     The y-coordinate of the upper-left corner of the bounding rectangle that
//     defines the ellipse.
//
//   width:
//     Width of the bounding rectangle that defines the ellipse.
//
//   height:
//     Height of the bounding rectangle that defines the ellipse.
//
// Exceptions:
//   System.ArgumentNullException:
//     pen is null.
public void DrawEllipse(Pen pen, int x, int y, int width, int height);

I know it's a bit late in the game, but I remembered this question from when it was new and I had a similar dillemma, and I accidently found the "right" solution, if anyone is still looking for one:

<path 
    d="
    M cx cy
    m -r, 0
    a r,r 0 1,0 (r * 2),0
    a r,r 0 1,0 -(r * 2),0
    "
/>

In other words, this:

<circle cx="100" cy="100" r="75" />

can be achieved as a path with this:

  <path 
        d="
        M 100, 100
        m -75, 0
        a 75,75 0 1,0 150,0
        a 75,75 0 1,0 -150,0
        "
  />

The trick is to have two arcs, the second one picking up where the first left off and using the negative diameter to get back to the original arc start point.

The reason it can't be done as a full circle in one arc (and I'm just speculating) is because you would be telling it to draw an arc from itself (let's say 150,150) to itself (150,150), which it renders as "oh, I'm already there, no arc necessary!".

The benefits of the solution I'm offering are:

1. it's easy to translate from a circle directly to a path, and
2. there is no overlap in the two arc lines (which may cause issues if you are using markers or patterns, etc). It's a clean continuous line, albeit drawn in two pieces.

None of this would matter if they would just allow textpaths to accept shapes. But I think they are avoiding that solution since shape elements like circle don't technically have a "start" point.

jsfiddle demo: http://jsfiddle.net/crazytonyi/mNt2g/

Update:

If you are using the path for a textPath reference and you are wanting the text to render on the outer edge of the arc, you would use the exact same method but change the sweep-flag from 0 to 1 so that it treats the outside of the path as the surface instead of the inside (think of 1,0 as someone sitting at the center and drawing a circle around themselves, while 1,1 as someone walking around the center at radius distance and dragging their chalk beside them, if that's any help). Here is the code as above but with the change:

<path 
    d="
    M cx cy
    m -r, 0
    a r,r 0 1,1 (r * 2),0
    a r,r 0 1,1 -(r * 2),0
    "
/>

I think it's important to add a thing, if you use the layout inflation that constructor in the drawview is not correct, add these constructors in the class:

public DrawingView(Context c, AttributeSet attrs) {
    super(c, attrs);
    ...
}

public DrawingView(Context c, AttributeSet attrs, int defStyle) {
    super(c, attrs, defStyle);
    ...
}

or the android system fails to inflate the layout file. I hope this could to help.

Do some transforms with the letter L

.checkmark {_x000D_
  font-family: arial;_x000D_
  -ms-transform: scaleX(-1) rotate(-35deg); /* IE 9 */_x000D_
  -webkit-transform: scaleX(-1) rotate(-35deg); /* Chrome, Safari, Opera */_x000D_
  transform: scaleX(-1) rotate(-35deg);_x000D_
}

<div class="checkmark">L</div>

Do not use Bitmap.Config.ARGB_8888

Instead use int w = WIDTH_PX, h = HEIGHT_PX;

Bitmap.Config conf = Bitmap.Config.ARGB_4444; // see other conf types
Bitmap bmp = Bitmap.createBitmap(w, h, conf); // this creates a MUTABLE bitmap
Canvas canvas = new Canvas(bmp);

// ready to draw on that bitmap through that canvas

ARGB_8888 can land you in OutOfMemory issues when dealing with more bitmaps or large bitmaps. Or better yet, try avoiding usage of ARGB option itself.

Note:drawRect and fillRect are different.

Draws the outline of the specified rectangle:

public void drawRect(int x,
        int y,
        int width,
        int height)

Fills the specified rectangle. The rectangle is filled using the graphics context's current color:

public abstract void fillRect(int x,
        int y,
        int width,
        int height)

public static void ToPrintConsole(this DataTable dataTable)
    {
        // Print top line
        Console.WriteLine(new string('-', 75));

        // Print col headers
        var colHeaders = dataTable.Columns.Cast<DataColumn>().Select(arg => arg.ColumnName);
        foreach (String s in colHeaders)
        {
            Console.Write("| {0,-20}", s);
        }
        Console.WriteLine();

        // Print line below col headers
        Console.WriteLine(new string('-', 75));

        // Print rows
        foreach (DataRow row in dataTable.Rows)
        {
            foreach (Object o in row.ItemArray)
            {
                Console.Write("| {0,-20}", o.ToString());
            }
            Console.WriteLine();
        }

        // Print bottom line
        Console.WriteLine(new string('-', 75));
    }

You can do something like this:

public void putOverlay(Bitmap bitmap, Bitmap overlay) {
    Canvas canvas = new Canvas(bitmap);
    Paint paint = new Paint(Paint.FILTER_BITMAP_FLAG);
    canvas.drawBitmap(overlay, 0, 0, paint);
} 

The idea is very simple: Once you associate a bitmap with a canvas, you can call any of the canvas' methods to draw over the bitmap.

This will work for bitmaps that have transparency. A bitmap will have transparency, if it has an alpha channel. Look at Bitmap.Config. You'd probably want to use ARGB_8888.

Important: Look at this Android sample for the different ways you can perform drawing. It will help you a lot.

Performance wise (memory-wise, to be exact), Bitmaps are the best objects to use, since they simply wrap a native bitmap. An ImageView is a subclass of View, and a BitmapDrawable holds a Bitmap inside, but it holds many other things as well. But this is an over-simplification. You can suggest a performance-specific scenario for a precise answer.

Here is my answer from a different question.

First you need to reference the Adobe Reader ActiveX Control

Adobe Acrobat Browser Control Type Library 1.0

%programfiles&\Common Files\Adobe\Acrobat\ActiveX\AcroPDF.dll

Then you just drag it into your Windows Form from the Toolbox.

And use some code like this to initialize the ActiveX Control.

private void InitializeAdobe(string filePath)
{
    try
    {
        this.axAcroPDF1.LoadFile(filePath);
        this.axAcroPDF1.src = filePath;
        this.axAcroPDF1.setShowToolbar(false);
        this.axAcroPDF1.setView("FitH");
        this.axAcroPDF1.setLayoutMode("SinglePage");
        this.axAcroPDF1.Show();
    }
    catch (Exception ex)
    {
        throw;
    }
}

Make sure when your Form closes that you dispose of the ActiveX Control

this.axAcroPDF1.Dispose();
this.axAcroPDF1 = null;

otherwise Acrobat might be left lying around.

You should be able to get an IWin32Window by by using PresentationSource.FromVisual and casting the result to HwndSource which implements IWin32Window.

Also in the comments here:

For localhost - I forgot to write in C:\Windows\System32\drivers\etc\hosts

127.0.0.1 localhost

Also removed proxy_pass http://127.0.0.1; from other server in ngnix.conf

As already mentioned in the answer by robertc, Chrome blocks certain functionality, like the geo location with local files. An easier alternative to setting up an own web server would be to just start Chrome with the parameter --allow-file-access-from-files. Then you can use the geo location, provided you didn't turn it off in your settings.

If you want to load a test resource file as a string with just few lines of code and without any extra dependencies, this does the trick:

public String loadResourceAsString(String fileName) throws IOException {
    Scanner scanner = new Scanner(getClass().getClassLoader().getResourceAsStream(fileName));
    String contents = scanner.useDelimiter("\\A").next();
    scanner.close();
    return contents;
}

"\\A" matches the start of input and there's only ever one. So this parses the entire file contents and returns it as a string. Best of all, it doesn't require any 3rd party libraries (like IOUTils).

In the iframe: So that means you have to add some code in the iframe page. Simply add this script to your code IN THE IFRAME:

<body onload="parent.alertsize(document.body.scrollHeight);">

In the holding page: In the page holding the iframe (in my case with ID="myiframe") add a small javascript:

<script>
function alertsize(pixels){
    pixels+=32;
    document.getElementById('myiframe').style.height=pixels+"px";
}
</script>

What happens now is that when the iframe is loaded it triggers a javascript in the parent window, which in this case is the page holding the iframe.

To that JavaScript function it sends how many pixels its (iframe) height is.

The parent window takes the number, adds 32 to it to avoid scrollbars, and sets the iframe height to the new number.

That's it, nothing else is needed.

But if you like to know some more small tricks keep on reading...

DYNAMIC HEIGHT IN THE IFRAME? If you like me like to toggle content the iframe height will change (without the page reloading and triggering the onload). I usually add a very simple toggle script I found online:

<script>
function toggle(obj) {
    var el = document.getElementById(obj);
    if ( el.style.display != 'block' ) el.style.display = 'block';
    else el.style.display = 'none';
}
</script>

to that script just add:

<script>
function toggle(obj) {
    var el = document.getElementById(obj);
    if ( el.style.display != 'block' ) el.style.display = 'block';
    else el.style.display = 'none';
    parent.alertsize(document.body.scrollHeight); // ADD THIS LINE!
}
</script>

How you use the above script is easy:

<a href="javascript:toggle('moreheight')">toggle height?</a><br />
<div style="display:none;" id="moreheight">
more height!<br />
more height!<br />
more height!<br />
</div>

For those that like to just cut and paste and go from there here is the two pages. In my case I had them in the same folder, but it should work cross domain too (I think...)

Complete holding page code:

This regex works well for me to validate password:

/[ !"#$%&'()*+,-./:;<=>?@[\\\]^_`{|}~]/

This list of special characters (including white space and punctuation) was taken from here: https://www.owasp.org/index.php/Password_special_characters. It was changed a bit, cause backslash ('\') and closing bracket (']') had to be escaped for proper work of the regex. That's why two additional backslash characters were added.

In XCode 8 you need to enable push in the Capabilities tab on your target, on top of enabling everything on the provisions and certificates: Xcode 8 "the aps-environment entitlement is missing from the app's signature" on submit

My blog post about this here.

From the documentation:

requests can also ignore verifying the SSL certificate if you set verify to False.

>>> requests.get('https://kennethreitz.com', verify=False)
<Response [200]>

If you're using a third-party module and want to disable the checks, here's a context manager that monkey patches requests and changes it so that verify=False is the default and suppresses the warning.

import warnings
import contextlib

import requests
from urllib3.exceptions import InsecureRequestWarning


old_merge_environment_settings = requests.Session.merge_environment_settings

@contextlib.contextmanager
def no_ssl_verification():
    opened_adapters = set()

    def merge_environment_settings(self, url, proxies, stream, verify, cert):
        # Verification happens only once per connection so we need to close
        # all the opened adapters once we're done. Otherwise, the effects of
        # verify=False persist beyond the end of this context manager.
        opened_adapters.add(self.get_adapter(url))

        settings = old_merge_environment_settings(self, url, proxies, stream, verify, cert)
        settings['verify'] = False

        return settings

    requests.Session.merge_environment_settings = merge_environment_settings

    try:
        with warnings.catch_warnings():
            warnings.simplefilter('ignore', InsecureRequestWarning)
            yield
    finally:
        requests.Session.merge_environment_settings = old_merge_environment_settings

        for adapter in opened_adapters:
            try:
                adapter.close()
            except:
                pass

Here's how you use it:

with no_ssl_verification():
    requests.get('https://wrong.host.badssl.com/')
    print('It works')

    requests.get('https://wrong.host.badssl.com/', verify=True)
    print('Even if you try to force it to')

requests.get('https://wrong.host.badssl.com/', verify=False)
print('It resets back')

session = requests.Session()
session.verify = True

with no_ssl_verification():
    session.get('https://wrong.host.badssl.com/', verify=True)
    print('Works even here')

try:
    requests.get('https://wrong.host.badssl.com/')
except requests.exceptions.SSLError:
    print('It breaks')

try:
    session.get('https://wrong.host.badssl.com/')
except requests.exceptions.SSLError:
    print('It breaks here again')

Note that this code closes all open adapters that handled a patched request once you leave the context manager. This is because requests maintains a per-session connection pool and certificate validation happens only once per connection so unexpected things like this will happen:

>>> import requests
>>> session = requests.Session()
>>> session.get('https://wrong.host.badssl.com/', verify=False)

You can revert by migrating to the previous migration.

For example, if your last two migrations are:

• 0010_previous_migration
• 0011_migration_to_revert

Then you would do:

./manage.py migrate my_app 0010_previous_migration 

You can then delete migration 0011_migration_to_revert.

If you're using Django 1.8+, you can show the names of all the migrations with

./manage.py showmigrations my_app

To reverse all migrations for an app, you can run:

./manage.py migrate my_app zero

Another way:

Regex.Replace(urlString, "www.(.+)", "$1");

Somehow, the Build checkbox in the Configuration Manager had been unchecked for my executable, so it was still running with the old Any CPU build. After I fixed that, Visual Studio complained that it couldn't debug the assembly, but that was fixed with a restart.

If you want to do this in jQuery instead of CSS, you basically follow the same process.

Assuming you have some <div id="target"></div>, you can use the following code:

$("#target").hover(function() {
    $(this).css('cursor','pointer');
}, function() {
    $(this).css('cursor','auto');
});

and that should do it.

The problem in my case was Jackson was trying to serialize an empty object with no attributes nor methods.

As suggested in the exception I added the following line to avoid failure on empty beans:

For Jackson 1.9

myObjectMapper.configure(SerializationConfig.Feature.FAIL_ON_EMPTY_BEANS, false);

For Jackson 2.X

myObjectMapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);

You can find a simple example on jackson disable fail_on_empty_beans

set -e stops the execution of a script if a command or pipeline has an error - which is the opposite of the default shell behaviour, which is to ignore errors in scripts. Type help set in a terminal to see the documentation for this built-in command.

The java.util.logging.Level documentation does a good job of defining when to use a log level and the target audience of that log level.

Most of the confusion with java.util.logging is in the tracing methods. It should be in the class level documentation but instead the Level.FINE field provides a good overview:

FINE is a message level providing tracing information. All of FINE, FINER, and FINEST are intended for relatively detailed tracing. The exact meaning of the three levels will vary between subsystems, but in general, FINEST should be used for the most voluminous detailed output, FINER for somewhat less detailed output, and FINE for the lowest volume (and most important) messages. In general the FINE level should be used for information that will be broadly interesting to developers who do not have a specialized interest in the specific subsystem. FINE messages might include things like minor (recoverable) failures. Issues indicating potential performance problems are also worth logging as FINE.

One important thing to understand which is not mentioned in the level documentation is that call-site tracing information is logged at FINER.

• Logger#entering A LogRecord with message "ENTRY", log level FINER, ...
• Logger#throwing The logging is done using the FINER level...The LogRecord's message is set to "THROW"
• Logger#exiting A LogRecord with message "RETURN", log level FINER...

If you log a message as FINE you will be able to configure logging system to see the log output with or without tracing log records surrounding the log message. So use FINE only when tracing log records are not required as context to understand the log message.

FINER indicates a fairly detailed tracing message. By default logging calls for entering, returning, or throwing an exception are traced at this level.

In general, most use of FINER should be left to call of entering, exiting, and throwing. That will for the most part reserve FINER for call-site tracing when verbose logging is turned on. When swallowing an expected exception it makes sense to use FINER in some cases as the alternative to calling trace throwing method since the exception is not actually thrown. This makes it look like a trace when it isn't a throw or an actual error that would be logged at a higher level.

FINEST indicates a highly detailed tracing message.

Use FINEST when the tracing log message you are about to write requires context information about program control flow. You should also use FINEST for tracing messages that produce large amounts of output data.

CONFIG messages are intended to provide a variety of static configuration information, to assist in debugging problems that may be associated with particular configurations. For example, CONFIG message might include the CPU type, the graphics depth, the GUI look-and-feel, etc.

The CONFIG works well for assisting system admins with the items listed above.

Typically INFO messages will be written to the console or its equivalent. So the INFO level should only be used for reasonably significant messages that will make sense to end users and system administrators.

Examples of this are tracing program startup and shutdown.

In general WARNING messages should describe events that will be of interest to end users or system managers, or which indicate potential problems.

An example use case could be exceptions thrown from AutoCloseable.close implementations.

In general SEVERE messages should describe events that are of considerable importance and which will prevent normal program execution. They should be reasonably intelligible to end users and to system administrators.

For example, if you have transaction in your program where if any one of the steps fail then all of the steps voided then SEVERE would be appropriate to use as the log level.

There are situations where allocating heap memory is very expensive compared to the operations performed. An example is matrix math. If you work with smallish matrices say 5 to 10 elements and do a lot of arithmetics the malloc overhead will be really significant. At the same time making the size a compile time constant does seem very wasteful and inflexible.

I think that C++ is so unsafe in itself that the argument to "try to not add more unsafe features" is not very strong. On the other hand, as C++ is arguably the most runtime efficient programming language features which makes it more so are always useful: People who write performance critical programs will to a large extent use C++, and they need as much performance as possible. Moving stuff from heap to stack is one such possibility. Reducing the number of heap blocks is another. Allowing VLAs as object members would one way to achieve this. I'm working on such a suggestion. It is a bit complicated to implement, admittedly, but it seems quite doable.

I'm not quite sure what you mean by "sorting the items after index 0", but if you just want to sort the array of strings returned by SerialPort.GetPortNames(), you can use Array.Sort.

The reason #2 fails is because sys.modules['module'] does not exist (the import routine has its own scope, and cannot see the module local name), and there's no module module or package on-disk. Note that you can separate multiple imported names by commas.

from package.subpackage.module import attribute1, attribute2, attribute3

Also:

from package.subpackage import module
print module.attribute1

For Windows:

1. Please add this directory to your environment variable(Path):

C:\mingw-w64\x86_64-8.1.0-win32-seh-rt_v6-rev0\mingw64\bin\

2. For Include errors detected, mention the path of your include folder into

"includePath": [ "C:/mingw-w64/x86_64-8.1.0-win32-seh-rt_v6-rev0/mingw64/include/" ]

, as this is the path from where the compiler fetches the library to be included in your program.

Change

$array=array_map('intval', explode(',', $string));

To:

$array= implode(',', array_map('intval', explode(',', $string)));

array_map returns an array, not a string. You need to convert the array to a comma separated string in order to use in the WHERE clause.

Here is a more complex statement that is useful when the length between '/' is unknown::

SELECT * FROM tableName
WHERE julianday(
    substr(substr(date, instr(date, '/')+1), instr(substr(date, instr(date, '/')+1), '/')+1)
||'-'||
    case when length(
    substr(date, instr(date, '/')+1, instr(substr(date, instr(date, '/')+1),'/')-1)
    )=2
    then
    substr(date, instr(date, '/')+1, instr(substr(date, instr(date, '/')+1), '/')-1)
    else
    '0'||substr(date, instr(date, '/')+1, instr(substr(date, instr(date, '/')+1), '/')-1)
    end
||'-'||
    case when length(substr(date,1, instr(date, '/')-1 )) =2
    then substr(date,1, instr(date, '/')-1 )
    else
    '0'||substr(date,1, instr(date, '/')-1 )
    end
) BETWEEN julianday('2015-03-14') AND julianday('2015-03-16') 

if(mas[i].indexOf("bird") == 0)
    //there is bird

You.can read about indexOf here: http://www.w3schools.com/jsref/jsref_indexof.asp

SELECT 'Y' REC_EXISTS             
FROM SALES                       
WHERE SALES_TYPE = 'Accessories'

The result will either be 'Y' or NULL. Simply test against 'Y'

The API does not support that directly. You can use the for(int i..) loop and count the elements or use subLists(0, size - 1) and handle the last element explicitly:

  if(x.isEmpty()) return;
  int last = x.size() - 1;
  for(Integer i : x.subList(0, last)) out.println(i);
  out.println("last " + x.get(last));

This is only useful if it does not introduce redundancy. It performs better than the counting version (after the subList overhead is amortized). (Just in case you cared after the boxing anyway).

The great thing about yyyy-mm-dd date format is that there is no need to extract month() and year(), you can do comparisons directly on strings:

SELECT *
  FROM your_table
  WHERE your_date_column >= '2010-09-01' AND your_date_column <= '2013-08-31';

Basic JS (good to learn): we use the Date() function and do all that we need to show the date and day in our custom format.

var myDate = new Date();_x000D_
_x000D_
let daysList = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];_x000D_
let monthsList = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Aug', 'Oct', 'Nov', 'Dec'];_x000D_
_x000D_
_x000D_
let date = myDate.getDate();_x000D_
let month = monthsList[myDate.getMonth()];_x000D_
let year = myDate.getFullYear();_x000D_
let day = daysList[myDate.getDay()];_x000D_
_x000D_
let today = `${date} ${month} ${year}, ${day}`;_x000D_
_x000D_
let amOrPm;_x000D_
let twelveHours = function (){_x000D_
    if(myDate.getHours() > 12)_x000D_
    {_x000D_
        amOrPm = 'PM';_x000D_
        let twentyFourHourTime = myDate.getHours();_x000D_
        let conversion = twentyFourHourTime - 12;_x000D_
        return `${conversion}`_x000D_
_x000D_
    }else {_x000D_
        amOrPm = 'AM';_x000D_
        return `${myDate.getHours()}`}_x000D_
};_x000D_
let hours = twelveHours();_x000D_
let minutes = myDate.getMinutes();_x000D_
_x000D_
let currentTime = `${hours}:${minutes} ${amOrPm}`;_x000D_
_x000D_
console.log(today + ' ' + currentTime);

Node JS (quick & easy): Install the npm pagckage using (npm install date-and-time), then run the below.

let nodeDate = require('date-and-time');
let now = nodeDate.format(new Date(), 'DD-MMMM-YYYY, hh:mm:ss a');
console.log(now);

check this one out.

<input type="text" name="firstname">
<input type="text" name="lastname">
<input type="text" name="email">
<input type="text" name="address">

<input type="text" name="tree[tree1][fruit]">
<input type="text" name="tree[tree1][height]">

<input type="text" name="tree[tree2][fruit]">
<input type="text" name="tree[tree2][height]">

<input type="text" name="tree[tree3][fruit]">
<input type="text" name="tree[tree3][height]">

it should end up like this in the $_POST[] array (PHP format for easy visualization)

$_POST[] = array(
    'firstname'=>'value',
    'lastname'=>'value',
    'email'=>'value',
    'address'=>'value',
    'tree' => array(
        'tree1'=>array(
            'fruit'=>'value',
            'height'=>'value'
        ),
        'tree2'=>array(
            'fruit'=>'value',
            'height'=>'value'
        ),
        'tree3'=>array(
            'fruit'=>'value',
            'height'=>'value'
        )
    )
)

Why not perform bitwise XOR? Two floating point numbers are equal if their corresponding bits are equal. I think, the decision to place the exponent bits before mantissa was made to speed up comparison of two floats. I think, many answers here are missing the point of epsilon comparison. Epsilon value only depends on to what precision floating point numbers are compared. For example, after doing some arithmetic with floats you get two numbers: 2.5642943554342 and 2.5642943554345. They are not equal, but for the solution only 3 decimal digits matter so then they are equal: 2.564 and 2.564. In this case you choose epsilon equal to 0.001. Epsilon comparison is also possible with bitwise XOR. Correct me if I am wrong.

You haven't actually asked a question, but assuming you have one, this could be your answer...

Assuming all characters, except the "Special Characters" are allowed you can write

String regex = "^[^<>'\"/;`%]*$";

Better way:

encodeURIComponent escapes all characters except the following: alphabetic, decimal digits, - _ . ! ~ * ' ( )

To avoid unexpected requests to the server, you should call encodeURIComponent on any user-entered parameters that will be passed as part of a URI. For example, a user could type "Thyme &time=again" for a variable comment. Not using encodeURIComponent on this variable will give comment=Thyme%20&time=again. Note that the ampersand and the equal sign mark a new key and value pair. So instead of having a POST comment key equal to "Thyme &time=again", you have two POST keys, one equal to "Thyme " and another (time) equal to again.

For application/x-www-form-urlencoded (POST), per http://www.w3.org/TR/html401/interac...m-content-type, spaces are to be replaced by '+', so one may wish to follow a encodeURIComponent replacement with an additional replacement of "%20" with "+".

If one wishes to be more stringent in adhering to RFC 3986 (which reserves !, ', (, ), and *), even though these characters have no formalized URI delimiting uses, the following can be safely used:

function fixedEncodeURIComponent (str) {
  return encodeURIComponent(str).replace(/[!'()]/g, escape).replace(/\*/g, "%2A");
}

This should work!

[HttpPost]
public ActionResult RedirectToImages(int id)
{
    return RedirectToAction("Index", "ProductImageManeger", new  { id = id });
}

[HttpGet]
public ViewResult Index(int id)
{
    return View(_db.ProductImages.Where(rs => rs.ProductId == id).ToList());
}

Notice that you don't have to pass the name of view if you are returning the same view as implemented by the action.

Your view should inherit the model as this:

@model <Your class name>

You can then access your model in view as:

@Model.<property_name>

For the vast majority^[1] of visitors here, the correct and simplest answer to the question "How do I list all remote branches in Git 1.7+?" is:

git branch -r

For a small minority^[1] git branch -r does not work. If git branch -r does not work try:

git ls-remote --heads <remote-name>

If git branch -r does not work, then maybe as Cascabel says "you've modified the default refspec, so that git fetch and git remote update don't fetch all the remote's branches".

^[1] As of the writing of this footnote 2018-Feb, I looked at the comments and see that the git branch -r works for the vast majority (about 90% or 125 out of 140).

If git branch -r does not work, check git config --get remote.origin.fetch contains a wildcard (*) as per this answer

The most upvoted answer can be improved.

Let me refer to GNU Make manual "Setting variables" and "Flavors", and add some comments.

Recursively expanded variables

The value you specify is installed verbatim; if it contains references to other variables, these references are expanded whenever this variable is substituted (in the course of expanding some other string). When this happens, it is called recursive expansion.

foo = $(bar)

The catch: foo will be expanded to the value of $(bar) each time foo is evaluated, possibly resulting in different values. Surely you cannot call it "lazy"! This can surprise you if executed on midnight:

# This variable is haunted!
WHEN = $(shell date -I)

something:
    touch $(WHEN).flag

# If this is executed on 00:00:00:000, $(WHEN) will have a different value!
something-else-later: something
    test -f $(WHEN).flag || echo "Boo!"

Simply expanded variable

VARIABLE := value
VARIABLE ::= value

Variables defined with ‘:=’ or ‘::=’ are simply expanded variables.

Simply expanded variables are defined by lines using ‘:=’ or ‘::=’ [...]. Both forms are equivalent in GNU make; however only the ‘::=’ form is described by the POSIX standard [...] 2012.

The value of a simply expanded variable is scanned once and for all, expanding any references to other variables and functions, when the variable is defined.

Not much to add. It's evaluated immediately, including recursive expansion of, well, recursively expanded variables.

The catch: If VARIABLE refers to ANOTHER_VARIABLE:

VARIABLE := $(ANOTHER_VARIABLE)-yohoho

and ANOTHER_VARIABLE is not defined before this assignment, ANOTHER_VARIABLE will expand to an empty value.

Assign if not set

FOO ?= bar

is equivalent to

ifeq ($(origin FOO), undefined)
FOO = bar
endif

where $(origin FOO) equals to undefined only if the variable was not set at all.

The catch: if FOO was set to an empty string, either in makefiles, shell environment, or command line overrides, it will not be assigned bar.

Appending

VAR += bar

Appending:

When the variable in question has not been defined before, ‘+=’ acts just like normal ‘=’: it defines a recursively-expanded variable. However, when there is a previous definition, exactly what ‘+=’ does depends on what flavor of variable you defined originally.

So, this will print foo bar:

VAR = foo
# ... a mile of code
VAR += $(BAR)
BAR = bar
$(info $(VAR))

but this will print foo:

VAR := foo
# ... a mile of code
VAR += $(BAR)
BAR = bar
$(info $(VAR))

The catch is that += behaves differently depending on what type of variable VAR was assigned before.

Multiline values

The syntax to assign multiline value to a variable is:

define VAR_NAME :=
line
line
endef

or

define VAR_NAME =
line
line
endef

Assignment operator can be omitted, then it creates a recursively-expanded variable.

define VAR_NAME
line
line
endef

The last newline before endef is removed.

Bonus: the shell assignment operator ‘!=’

 HASH != printf '\043'

is the same as

HASH := $(shell printf '\043')

Don't use it. $(shell) call is more readable, and the usage of both in a makefiles is highly discouraged. At least, $(shell) follows Joel's advice and makes wrong code look obviously wrong.

The problem is the shape of the data (pd dataframe) you are passing to the fit function. You've got to pass 1d list.

I ran into this problem recently and wrote up a post about the particular case in our code that was causing this problem.

http://cappuccino.org/discuss/2010/03/01/internet-explorer-global-variables-and-stack-overflows/

The quick summary is: recursion that passes through the host global object is limited to a stack depth of 13. In other words, if the reference your function call is using (not necessarily the function itself) was defined with some form window.foo = function, then recursing through foo is limited to a depth of 13.

And sending just some "ping" message from server to client every x second resolved problem

I needed to export our security log and wanted the date and time in Coordinated Universal Time. This proved to be a challenge to figure out, but so simple to execute:

wevtutil export-log security c:\users\%username%\SECURITYEVENTLOG-%computername%-$(((get-date).ToUniversalTime()).ToString("yyyyMMddTHHmmssZ")).evtx

The magic code is just this part:

$(((get-date).ToUniversalTime()).ToString("yyyyMMddTHHmmssZ"))

Include the class that you are using Within your text file, then intelliSense will know where to look when you type within your text file. This works for me.

So it’s important to check the Unreal API to see where the included class is so that you have the path to type on the include line. Hope that makes sense.

This worked for me:

#image-id {
    position: absolute;
    top: 0; left: 0; right: 0; bottom: 0;
    width: auto;
    margin: 0 auto;
}

As of JavaScript 1.8.5 you can use Object.keys(obj) to get an Array of properties defined on the object itself (the ones that return true for obj.hasOwnProperty(key)).

Object.keys(obj).forEach(function(key,index) {
    // key: the name of the object key
    // index: the ordinal position of the key within the object 
});

This is better (and more readable) than using a for-in loop.

Its supported on these browsers:

• Firefox (Gecko): 4 (2.0)
• Chrome: 5
• Internet Explorer: 9

See the Mozilla Developer Network Object.keys()'s reference for futher information.

ArrayList implements the List Interface.

If you look at the Javadoc for List at the contains method you will see that it uses the equals() method to evaluate if two objects are the same.

The function you need is CInt.

ie CInt(PrinterLabel)

See Type Conversion Functions (Visual Basic) on MSDN

Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!

SQL Server 2012 and up support LAG / LEAD functions to access the previous or subsequent row. SQL Server 2005 does not support this (in SQL2005 you need a join or something else).

A SQL 2012 example on this data

/* Prepare */
select * into #tmp
from
(
    select 2  as rowint,      23 as Value
    union select 3,       45
    union select 17,      10
    union select 9,       0
) x


/* The SQL 2012 query */
select rowInt, Value, LEAD(value) over (order by rowInt) - Value  
from #tmp

LEAD(value) will return the value of the next row in respect to the given order in "over" clause.

You can use array_agg function for that:

SELECT "Movie",
array_to_string(array_agg(distinct "Actor"),',') AS Actor
FROM Table1
GROUP BY "Movie";

Result:

See this SQLFiddle

For more See 9.18. Aggregate Functions

When you do -

for word in string:

You are not iterating through the words in the string, you are iterating through the characters in the string. To iterate through the words, you would first need to split the string into words , using str.split() , and then iterate through that . Example -

my_string = "this is a string"
for word in my_string.split():
    print (word)

Please note, str.split() , without passing any arguments splits by all whitespaces (space, multiple spaces, tab, newlines, etc).

Using Pygrok, you can define abstracted extensions to the Regular Expression syntax.

The custom patterns can be included in your regex in the format %{PATTERN_NAME}.

You can also create a label for that pattern, by separating with a colon: %s{PATTERN_NAME:matched_string}. If the pattern matches, the value will be returned as part of the resulting dictionary (e.g. result.get('matched_string'))

For example:

from pygrok import Grok

input_string = 'monkey 2010-07-10 love banana'
date_pattern = '%{YEAR:year}-%{MONTHNUM:month}-%{MONTHDAY:day}'

grok = Grok(date_pattern)
print(grok.match(input_string))

The resulting value will be a dictionary:

{'month': '07', 'day': '10', 'year': '2010'}

If the date_pattern does not exist in the input_string, the return value will be None. By contrast, if your pattern does not have any labels, it will return an empty dictionary {}

On Win with MSVC there's __try ... __except ... but it's really horrible and you don't want to use it if you can possibly avoid it. Better to say that there are no exceptions.

Create a temporary element, then clone() and append():

$('<div>').append($('#xxx').clone()).html();

way of getting home directory of current user is

String currentUsersHomeDir = System.getProperty("user.home");

and to append path separator

String otherFolder = currentUsersHomeDir + File.separator + "other";

File.separator

The system-dependent default name-separator character, represented as a string for convenience. This string contains a single character, namely separatorChar.

For me, as of Google Chrome Version 46.0.2490.71 m, the Headers info area is a little hidden. To access:

You can simply add multiple conditions by adding them as where() inside the join closure

->leftJoin('table2 AS b', function($join){
        $join->on('a.field1', '=', 'b.field2')
        ->where('b.field3', '=', true)
        ->where('b.field4', '=', '1');
})

In Java threads are not killed, but the stopping of a thread is done in a cooperative way. The thread is asked to terminate and the thread can then shutdown gracefully.

Often a volatile boolean field is used which the thread periodically checks and terminates when it is set to the corresponding value.

I would not use a boolean to check whether the thread should terminate. If you use volatile as a field modifier, this will work reliable, but if your code becomes more complex, for instead uses other blocking methods inside the while loop, it might happen, that your code will not terminate at all or at least takes longer as you might want.

Certain blocking library methods support interruption.

Every thread has already a boolean flag interrupted status and you should make use of it. It can be implemented like this:

public void run() {
   try {
      while (!interrupted()) {
         // ...
      }
   } catch (InterruptedException consumed)
      /* Allow thread to exit */
   }
}

public void cancel() { interrupt(); }

Source code adapted from Java Concurrency in Practice. Since the cancel() method is public you can let another thread invoke this method as you wanted.

Corrected a few things and added an alternative select - delete as appropriate.

Running a different copy of Python is as easy as starting the correct executable. You mention that you've started a python instance, from the command line, by simply typing python.

What this does under Windows, is to trawl the %PATH% environment variable, checking for an executable, either batch file (.bat), command file (.cmd) or some other executable to run (this is controlled by the PATHEXT environment variable), that matches the name given. When it finds the correct file to run the file is being run.

Now, if you've installed two python versions 2.5 and 2.6, the path will have both of their directories in it, something like PATH=c:\python\2.5;c:\python\2.6 but Windows will stop examining the path when it finds a match.

What you really need to do is to explicitly call one or both of the applications, such as c:\python\2.5\python.exe or c:\python\2.6\python.exe.

The other alternative is to create a shortcut to the respective python.exe calling one of them python25 and the other python26; you can then simply run python25 on your command line.

I used Refractor to recover my script/code from dll file.

Here I am providing a negative example where your want to avoid when converting floating number to strings.

float num=99.463;
float tmp1=round(num*1000);
float tmp2=tmp1/1000;
cout << tmp1 << " " << tmp2 << " " << to_string(tmp2) << endl;

You get

99463 99.463 99.462997

Note: the num variable can be any value close to 99.463, you will get the same print out. The point is to avoid the convenient c++11 "to_string" function. It took me a while to get out this trap. The best way is the stringstream and sprintf methods (C language). C++11 or newer should provided a second parameter as the number of digits after the floating point to show. Right now the default is 6. I am positing this so that others won't wast time on this subject.

I wrote my first version, please let me know if you find any bug that needs to be fixed. You can control the exact behavior with the iomanipulator. My function is for showing the number of digits after the decimal point.

string ftos(float f, int nd) {
   ostringstream ostr;
   int tens = stoi("1" + string(nd, '0'));
   ostr << round(f*tens)/tens;
   return ostr.str();

        mail($to,utf8_to_latin2($s),utf8_to_latin2($text),
        "From: $form\r\n".
        "Reply-To: $reply\r\n".
        "X-Mailer: PHP/" . phpversion());
    }

I have made another mailer function, because apple device could not read well the previous version.

function utf8mail($to,$s,$body,$from_name="x",$from_a = "[email protected]", $reply="[email protected]")
{
    $s= "=?utf-8?b?".base64_encode($s)."?=";
    $headers = "MIME-Version: 1.0\r\n";
    $headers.= "From: =?utf-8?b?".base64_encode($from_name)."?= <".$from_a.">\r\n";
    $headers.= "Content-Type: text/plain;charset=utf-8\r\n";
    $headers.= "Reply-To: $reply\r\n";  
    $headers.= "X-Mailer: PHP/" . phpversion();
    mail($to, $s, $body, $headers);
}

Steps :

1. su -- To switch to super user.
2. setprop service.adb.tcp.port 5555 - To specify the tcp Port - 5555 is the port number here
3. stop adbd - To stop the adbd service.
4. start adbd - To start adbd service.

this works perfectly with ssh from my windows PC

I try to do this on the boot on my cyanogen mobile or launch this with plink. With plink I can't launch shell with su right ... sudo or su command not works. On boot I don't know how it's works! My shell program works from ssh with su -c "sh /storage/sdcard1/start_adb.sh" with the last 3 commands (without su --)

Thanks

an Event will fire multiple time when it is registered multiple times (even if to the same handler).

eg $("ctrl").on('click', somefunction) if this piece of code is executed every time the page is partially refreshed, the event is being registered each time too. Hence even if the ctrl is clicked only once it may execute "somefunction" multiple times - how many times it execute will depend on how many times it was registered.

this is true for any event registered in javascript.

solution:

ensure to call "on" only once.

and for some reason if you cannot control the architecture then do this:

$("ctrl").off('click'); $("ctrl").on('click', somefunction);

The accepted answer is not always correct. If you configure binary logging on MySQL, you can rollback the database to any previous point you still have a snapshot and binlog for.

7.5 Point-in-Time (Incremental) Recovery Using the Binary Log is a good starting point for learning about this facility.

A Pure Python solution.
Does not rely on either ANSI, or external commands.
Only your terminal has to have the ability to tell you how many lines are in view.

from shutil import get_terminal_size
print("\n" * get_terminal_size().lines, end='')

Python version >= 3.3.0

Another way to cope with it is to use Cygwin, depending on what do you want to do with the files (i.e. if Cygwin commands suit your needs)

For example it allows to copy, move or rename files that even Windows Explorer can't. Or of course deal with the contents of them like md5sum, grep, gzip, etc.

Also for programs that you are coding, you could link them to the Cygwin DLL and it would enable them to use long paths (I haven't tested this though)

I've had the same error and I solve it with: git merge -s recursive -X theirs origin/master

I am not 100% sure what the conditions are for this, but for me the above didn't work directly, thought it got close. I think it was because I needed "id" for my view by in the model it was called "ObjectID".

I had a model with a variety of pieces of information. I just needed the id.

Before the above I created a new System.Web.Routing.RouteValueDictionary object and added the needed id.

(System.Web.Routing.)RouteValueDictionary RouteInfo = new RouteValueDictionary();
RouteInfo.Add("id", ObjectID);
return RedirectToAction("details", RouteInfo);

(Note: the MVC project in question I didn't create, so I don't know where all the right "fiddly" bits are.)

Maybe this will help

awk '$3 ~ /snow|snowman/' dummy_file

You can use strcmp:

break x:20 if strcmp(y, "hello") == 0

20 is line number, x can be any filename and y can be any variable.

You can MongoDB aggregation to do the task:

db.collection.aggregate([
  {
    $addFields: {
      arrayLength: {$size: '$array'}
    },
  },
  {
    $match: {
      arrayLength: {$gt: 1}
    },
  },
])

Nope, this cannot be done since opacity affects the whole element including its content and there's no way to alter this behavior. You can work around this with the two following methods.

Secondary div

Add another div element to the container to hold the background. This is the most cross-browser friendly method and will work even on IE6.

HTML

<div class="myDiv">
    <div class="bg"></div>
    Hi there
</div>

CSS

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

.myDiv .bg {
    position: absolute;
    z-index: -1;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    background: url(test.jpg) center center;
    opacity: .4;
    width: 100%;
    height: 100%;
}

See test case on jsFiddle

:before and ::before pseudo-element

Another trick is to use the CSS 2.1 :before or CSS 3 ::before pseudo-elements. :before pseudo-element is supported in IE from version 8, while the ::before pseudo-element is not supported at all. This will hopefully be rectified in version 10.

HTML

<div class="myDiv">
    Hi there
</div>

CSS

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

.myDiv:before {
    content: "";
    position: absolute;
    z-index: -1;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    background: url(test.jpg) center center;
    opacity: .4;
}

Additional notes

Due to the behavior of z-index you will have to set a z-index for the container as well as a negative z-index for the background image.

Test cases

See test case on jsFiddle:

• Using CSS 2.1 :before
• Using CSS 3 ::before

You can set the border color in IE however there are some issues.

Argh... I could have sworn you could do this... just tested and realized I wasn't correct. The notes below still apply though.

1. in IE8 (Beta1 -> RC1) changing the border color or the background color/image causes a de-theming of the control in WindowsXP (the drop arrow and box look like Windows 95)

2. you still can't style the options within the select control very well because IE doesn't support it. (see bug #291)

Add ID attributes with same values as name attributes and then you can do this:

$('#first_name').change(function () {
  $('#firstname').val($(this).val());
});

I believe this is what you're looking for:

char[] characters = "this is a test".ToCharArray();

I wrote a Tester class which can test the performance:

public class Tester
{
    public static void main(String[] args)
    {
        String text = "";

        int loopCount = 10000000;
        long startTime, endTime, duration1, duration2;

        startTime = System.nanoTime();
        for (int i = 0; i < loopCount; i++) {
            text.equals("");
        }
        endTime = System.nanoTime();
        duration1 = endTime - startTime;
        System.out.println(".equals(\"\") duration " +": \t" + duration1);

        startTime = System.nanoTime();
        for (int i = 0; i < loopCount; i++) {
            text.isEmpty();
        }
        endTime = System.nanoTime();
        duration2 = endTime - startTime;
        System.out.println(".isEmpty() duration "+": \t\t" + duration2);

        System.out.println("isEmpty() to equals(\"\") ratio: " + ((float)duration2 / (float)duration1));
    }
}

I found that using .isEmpty() took around half the time of .equals("").

First, convert your ButtonField or CommandField to a TemplateField, then bind the Visible property of the button to a method that implements the business logic:

<asp:GridView runat="server" ID="GV1" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:BoundField DataField="Age" HeaderText="Age" />
        <asp:TemplateField>
            <ItemTemplate>
                <asp:Button runat="server" Text="Reject" 
                Visible='<%# IsOverAgeLimit((Decimal)Eval("Age")) %>' 
                CommandName="Select"/>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

Then, in the code behind, add in the method:

protected Boolean IsOverAgeLimit(Decimal Age) {
    return Age > 35M;
}

The advantage here is you can test the IsOverAgeLimit method fairly easily.

There is a getTime() method (unsure why it's not called getDate).

Edit: Just realized you need a java.sql.Date. One of the answers which use cal.getTimeInMillis() is what you need.

First copy the source range then paste-special on target range with Transpose:=True, short sample:

Option Explicit

Sub test()
  Dim sourceRange As Range
  Dim targetRange As Range

  Set sourceRange = ActiveSheet.Range(Cells(1, 1), Cells(5, 1))
  Set targetRange = ActiveSheet.Cells(6, 1)

  sourceRange.Copy
  targetRange.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:=False, Transpose:=True
End Sub

The Transpose function takes parameter of type Varaiant and returns Variant.

  Sub transposeTest()
    Dim transposedVariant As Variant
    Dim sourceRowRange As Range
    Dim sourceRowRangeVariant As Variant

    Set sourceRowRange = Range("A1:H1") ' one row, eight columns
    sourceRowRangeVariant = sourceRowRange.Value
    transposedVariant = Application.Transpose(sourceRowRangeVariant)

    Dim rangeFilledWithTransposedData As Range
    Set rangeFilledWithTransposedData = Range("I1:I8") ' eight rows, one column
    rangeFilledWithTransposedData.Value = transposedVariant
  End Sub

I will try to explaine the purpose of 'calling transpose twice'. If u have row data in Excel e.g. "a1:h1" then the Range("a1:h1").Value is a 2D Variant-Array with dimmensions 1 to 1, 1 to 8. When u call Transpose(Range("a1:h1").Value) then u get transposed 2D Variant Array with dimensions 1 to 8, 1 to 1. And if u call Transpose(Transpose(Range("a1:h1").Value)) u get 1D Variant Array with dimension 1 to 8.

First Transpose changes row to column and second transpose changes the column back to row but with just one dimension.

If the source range would have more rows (columns) e.g. "a1:h3" then Transpose function just changes the dimensions like this: 1 to 3, 1 to 8 Transposes to 1 to 8, 1 to 3 and vice versa.

Hope i did not confuse u, my english is bad, sorry :-).

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

i couldn't change the permissions on the sharepoint i'm using but got a round it by uploading .url files with the drag and drop multiple files uploader.

Using the normal upload didn't work because they are intepreted by the file open dialog when you try to open them singly so it just tries to open the target not the .url file.

.url files can be made by saving a favourite with internet exploiter.

You retrieve the system property that marks the bitness of this JVM with:

System.getProperty("sun.arch.data.model");

Possible results are:

• "32" – 32-bit JVM
• "64" – 64-bit JVM
• "unknown" – Unknown JVM

As described in the HotSpot FAQ:

When writing Java code, how do I distinguish between 32 and 64-bit operation?

There's no public API that allows you to distinguish between 32 and 64-bit operation. Think of 64-bit as just another platform in the write once, run anywhere tradition. However, if you'd like to write code which is platform specific (shame on you), the system property sun.arch.data.model has the value "32", "64", or "unknown".

An example where this could be necessary is if your Java code depends on native libraries, and you need to determine whether to load the 32- or 64-bit version of the libraries on startup.

const dates = getDatesFromDateRange("2014-05-02", "2018-05-12", "YYYY/MM/DD", 1);           
console.log(dates);
// you get the whole from-to date ranges as per parameters
var onlyStartDates = dates.map(dateObj => dateObj["to"]);
console.log(onlyStartDates);
// moreover, if you want only from dates then you can grab by "map" function

function getDatesFromDateRange( startDate, endDate, format, counter ) {
    startDate = moment(startDate, format);
    endDate = moment(endDate, format);

    let dates = [];
    let fromDate = startDate.clone();
    let toDate = fromDate.clone().add(counter, "month").startOf("month").add(-1, "day");
    do {
        dates.push({
            "from": fromDate.format(format),
            "to": ( toDate < endDate ) ? toDate.format(format) : endDate.format(format)
        });
        fromDate = moment(toDate, format).add(1, "day").clone();
        toDate = fromDate.clone().add(counter, "month").startOf("month").add(-1, "day");
    } while ( fromDate < endDate );
    return dates;
}

Please note, .clone() is essential in momentjs else it'll override the value. It seems in your case.

It's more generic, to get bunch of dates that fall between dates.

For is()

You want to use DATEADD, using a negative duration. e.g.

While you can configure Vim's indentation just fine using the indent plugin or manually using the settings, I recommend using a python script called Vindect that automatically sets the relevant settings for you when you open a python file. Use this tip to make using Vindect even more effective. When I first started editing python files created by others with various indentation styles (tab vs space and number of spaces), it was incredibly frustrating. But Vindect along with this indent file

Also recommend:

• pythonhelper
• python_match
• python_ifold

One way to make sure a method from a class is not called is to override the method with a dummy.

    WebFormCreatorActivity activity = spy(new WebFormCreatorActivity(clientFactory) {//spy(new WebFormCreatorActivity(clientFactory));
            @Override
            public void select(TreeItem i) {
                log.debug("SELECT");
            };
        });

A Monitor is an object designed to be accessed from multiple threads. The member functions or methods of a monitor object will enforce mutual exclusion, so only one thread may be performing any action on the object at a given time. If one thread is currently executing a member function of the object then any other thread that tries to call a member function of that object will have to wait until the first has finished.

A Semaphore is a lower-level object. You might well use a semaphore to implement a monitor. A semaphore essentially is just a counter. When the counter is positive, if a thread tries to acquire the semaphore then it is allowed, and the counter is decremented. When a thread is done then it releases the semaphore, and increments the counter.

If the counter is already zero when a thread tries to acquire the semaphore then it has to wait until another thread releases the semaphore. If multiple threads are waiting when a thread releases a semaphore then one of them gets it. The thread that releases a semaphore need not be the same thread that acquired it.

A monitor is like a public toilet. Only one person can enter at a time. They lock the door to prevent anyone else coming in, do their stuff, and then unlock it when they leave.

A semaphore is like a bike hire place. They have a certain number of bikes. If you try and hire a bike and they have one free then you can take it, otherwise you must wait. When someone returns their bike then someone else can take it. If you have a bike then you can give it to someone else to return --- the bike hire place doesn't care who returns it, as long as they get their bike back.

This works for me always please run following commands:

1.git add .
2.git commit -m "no bugs please"
3.git push origin *

where * is based off the branch you are pushing to, and also commit messages can always be changed to suit the context.

Not a definite answer but too much to fit in comments:

I hypothesize they gave you a cert that either has a wrong issuer (although their server could use a more specific alert code for that) or a wrong subject. We know the cert matches your privatekey -- because both curl and openssl client paired them without complaining about a mismatch; but we don't actually know it matches their desired CA(s) -- because your curl uses openssl and openssl SSL client does NOT enforce that a configured client cert matches certreq.CAs.

Do openssl x509 <clientcert.pem -noout -subject -issuer and the same on the cert from the test P12 that works. Do openssl s_client (or check the one you did) and look under Acceptable client certificate CA names; the name there or one of them should match (exactly!) the issuer(s) of your certs. If not, that's most likely your problem and you need to check with them you submitted your CSR to the correct place and in the correct way. Perhaps they have different regimes in different regions, or business lines, or test vs prod, or active vs pending, etc.

If the issuer of your cert does match desiredCAs, compare its subject to the working (test-P12) one: are they in similar format? are there any components in the working one not present in yours? If they allow it, try generating and submitting a new CSR with a subject name exactly the same as the test-P12 one, or as close as you can get, and see if that produces a cert that works better. (You don't have to generate a new key to do this, but if you choose to, keep track of which certs match which keys so you don't get them mixed up.) If that doesn't help look at the certificate extensions with openssl x509 <cert -noout -text for any difference(s) that might reasonably be related to subject authorization, like KeyUsage, ExtendedKeyUsage, maybe Policy, maybe Constraints, maybe even something nonstandard.

If all else fails, ask the server operator(s) what their logs say about the problem, or if you have access look at the logs yourself.

Did you load jQuery in head section? Did you load it correctly?

<head>
   <script src="scripts/jquery.js"></script>
   ...
</head>

This code assumes jquery.js is in scripts directory. (You can change file name if you like)

You can also use jQuery as hosted by Google:

<head>
   <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
   ...
</head>

As per your comment:

Apparently, your web server is not configured to return jQuery-1.6.1.js on requesting /webProject/jquery-1.6.1.js. There may be numerous reasons for this, such as wrong file name, folder name, routing settings, etc. You need to create another question and describe your 404 in greater details (such as local file name, operation system, webserver name and settings).

Again, you can use jQuery as provided by Google (see above), however you still might want to find out why some local files don't get served on request.

Would something like

(pattern.*?(pattern))*

work for you?

Edit:

The problem with this is that it uses the non-greedy operator *?, which can require an awful lot of backtracking along the string instead of just looking at each letter once. What this means for you is that this could be slow for large gaps.

The first one is the "short" form - you use it, when you do not want to do something fancy with your getters and setters. It is not possible to execute a method or something like that in this form.

The second and third form are almost identical, albeit the second one is compressed to one line. This form is discouraged by stylecop because it looks somewhat weird and does not conform to C' Stylguides.

I would use the third form if I expectd to use my getters / setters for something special, e.g. use a lazy construct or so.

import android.support.v7.widget.RecyclerView;

In Android Studio, importing is not as intuitive as one would hope. Try importing this bit and see how it helps!

The semantics of setTimeout are roughly the same as in a web browser: the timeout arg is a minimum number of ms to wait before executing, not a guarantee. Furthermore, passing 0, a non-number, or a negative number, will cause it to wait a minimum number of ms. In Node, this is 1ms, but in browsers it can be as much as 50ms.

The reason for this is that there is no preemption of JavaScript by JavaScript. Consider this example:

setTimeout(function () {
  console.log('boo')
}, 100)
var end = Date.now() + 5000
while (Date.now() < end) ;
console.log('imma let you finish but blocking the event loop is the best bug of all TIME')

The flow here is:

1. schedule the timeout for 100ms.
2. busywait for 5000ms.
3. return to the event loop. check for pending timers and execute.

If this was not the case, then you could have one bit of JavaScript "interrupt" another. We'd have to set up mutexes and semaphors and such, to prevent code like this from being extremely hard to reason about:

var a = 100;
setTimeout(function () {
  a = 0;
}, 0);
var b = a; // 100 or 0?

The single-threadedness of Node's JavaScript execution makes it much simpler to work with than most other styles of concurrency. Of course, the trade-off is that it's possible for a badly-behaved part of the program to block the whole thing with an infinite loop.

Is this a better demon to battle than the complexity of preemption? That depends.

I think there is an another way to understand it.

For a np.array,if we want eliminate columns we use axis = 1; if we want eliminate rows, we use axis = 0.

np.mean(np.array(np.ones(shape=(3,5,10))),axis = 0).shape # (5,10)
np.mean(np.array(np.ones(shape=(3,5,10))),axis = 1).shape # (3,10)
np.mean(np.array(np.ones(shape=(3,5,10))),axis = (0,1)).shape # (10,)

For pandas object, axis = 0 stands for row-wise operation and axis = 1 stands for column-wise operation. This is different from numpy by definition, we can check definitions from numpy.doc and pandas.doc

Here is how I solve this. I just pipe the output to Out-String and then pass that output to the .NET Trim function:

(gci | ft -HideTableHeaders | Out-String).Trim()

This will strip out the line breaks before and after the table.

You can also use TrimStart to just take care of the header's line break if you still want the trailing line breaks.

(gci | ft -HideTableHeaders | Out-String).TrimStart()

My first thought is you could use git rev-list HEAD, which lists all the revs in reverse chronological order, in combination with git tag --contains. When you find a ref where git tag --contains produces a nonempty list, you have found the most recent tag(s).

string textboxID;
string da;
textboxID = "ctl00$MainContent$grd$ctl" + (grd.Columns.Count + j).ToString() + "$txtDyna" + (k).ToString();
textboxID= ctl00$MainContent$grd$ctl12$ctl00;
da = Request.Form(textboxID);

Much better to use following:

For is not null:

where('archived IS NOT NULL', null);

For is null:

where('archived', null);

using maxlength attribute of textarea would do the trick ... simple html code .. not JS or JQuery or Server Side Check Required....

I am using Spyder (Python 2.7) and to clean the interpreter console I use either

%clear

that forces the command line to go to the top and I will not see the previous old commands.

or I click "option" on the Console environment and select "Restart kernel" that removes everything.

In addition to previous answers, in case of you need to validate a JSON format like "{}", you can use the following code:

const validateJSON = (str) => {
  try {
    const json = JSON.parse(str);
    if (Object.prototype.toString.call(json).slice(8,-1) !== 'Object') {
      return false;
    }
  } catch (e) {
    return false;
  }
  return true;
}

Examples of usage:

validateJSON('{}')
true
validateJSON('[]')
false
validateJSON('')
false
validateJSON('2134')
false
validateJSON('{ "Id": 1, "Name": "Coke" }')
true

There are many ways of doing.

1) Use symbols. It won't give you any type safety, though, aside from not accepting non-symbols where a symbol is expected. I'm only mentioning it here for completeness. Here's an example of usage:

def update(what: Symbol, where: Int, newValue: Array[Int]): MatrixInt =
  what match {
    case 'row => replaceRow(where, newValue)
    case 'col | 'column => replaceCol(where, newValue)
    case _ => throw new IllegalArgumentException
  }

// At REPL:   
scala> val a = unitMatrixInt(3)
a: teste7.MatrixInt =
/ 1 0 0 \
| 0 1 0 |
\ 0 0 1 /

scala> a('row, 1) = a.row(0)
res41: teste7.MatrixInt =
/ 1 0 0 \
| 1 0 0 |
\ 0 0 1 /

scala> a('column, 2) = a.row(0)
res42: teste7.MatrixInt =
/ 1 0 1 \
| 0 1 0 |
\ 0 0 0 /

2) Using class Enumeration:

object Dimension extends Enumeration {
  type Dimension = Value
  val Row, Column = Value
}

or, if you need to serialize or display it:

object Dimension extends Enumeration("Row", "Column") {
  type Dimension = Value
  val Row, Column = Value
}

This can be used like this:

def update(what: Dimension, where: Int, newValue: Array[Int]): MatrixInt =
  what match {
    case Row => replaceRow(where, newValue)
    case Column => replaceCol(where, newValue)
  }

// At REPL:
scala> a(Row, 2) = a.row(1)
<console>:13: error: not found: value Row
       a(Row, 2) = a.row(1)
         ^

scala> a(Dimension.Row, 2) = a.row(1)
res1: teste.MatrixInt =
/ 1 0 0 \
| 0 1 0 |
\ 0 1 0 /

scala> import Dimension._
import Dimension._

scala> a(Row, 2) = a.row(1)
res2: teste.MatrixInt =
/ 1 0 0 \
| 0 1 0 |
\ 0 1 0 /

Unfortunately, it doesn't ensure that all matches are accounted for. If I forgot to put Row or Column in the match, the Scala compiler wouldn't have warned me. So it gives me some type safety, but not as much as can be gained.

3) Case objects:

sealed abstract class Dimension
case object Row extends Dimension
case object Column extends Dimension

Now, if I leave out a case on a match, the compiler will warn me:

MatrixInt.scala:70: warning: match is not exhaustive!
missing combination         Column

    what match {
    ^
one warning found

It's used pretty much the same way, and doesn't even need an import:

scala> val a = unitMatrixInt(3)
a: teste3.MatrixInt =
/ 1 0 0 \
| 0 1 0 |
\ 0 0 1 /

scala> a(Row,2) = a.row(0)
res15: teste3.MatrixInt =
/ 1 0 0 \
| 0 1 0 |
\ 1 0 0 /

You might wonder, then, why ever use an Enumeration instead of case objects. As a matter of fact, case objects do have advantages many times, such as here. The Enumeration class, though, has many Collection methods, such as elements (iterator on Scala 2.8), which returns an Iterator, map, flatMap, filter, etc.

This answer is essentially a selected parts from this article in my blog.

I would recommend you using the Conditional Attribute!

Update: 3.5 years later

You can use #if like this (example copied from MSDN):

// preprocessor_if.cs
#define DEBUG
#define VC_V7
using System;
public class MyClass 
{
    static void Main() 
    {
#if (DEBUG && !VC_V7)
        Console.WriteLine("DEBUG is defined");
#elif (!DEBUG && VC_V7)
        Console.WriteLine("VC_V7 is defined");
#elif (DEBUG && VC_V7)
        Console.WriteLine("DEBUG and VC_V7 are defined");
#else
        Console.WriteLine("DEBUG and VC_V7 are not defined");
#endif
    }
}

Only useful for excluding parts of methods.

If you use #if to exclude some method from compilation then you will have to exclude from compilation all pieces of code which call that method as well (sometimes you may load some classes at runtime and you cannot find the caller with "Find all references"). Otherwise there will be errors.

If you use conditional compilation on the other hand you can still leave all pieces of code that call the method. All parameters will still be validated by the compiler. The method just won't be called at runtime. I think that it is way better to hide the method just once and not have to remove all the code that calls it as well. You are not allowed to use the conditional attribute on methods which return value - only on void methods. But I don't think this is a big limitation because if you use #if with a method that returns a value you have to hide all pieces of code that call it too.

Here is an example:

    // calling Class1.ConditionalMethod() will be ignored at runtime 
    // unless the DEBUG constant is defined


    using System.Diagnostics;
    class Class1 
    {
       [Conditional("DEBUG")]
       public static void ConditionalMethod() {
          Console.WriteLine("Executed Class1.ConditionalMethod");
       }
    }

Summary:

I would use #ifdef in C++ but with C#/VB I would use Conditional attribute. This way you hide the method definition without having to hide the pieces of code that call it. The calling code is still compiled and validated by the compiler, the method is not called at runtime though. You may want to use #if to avoid dependencies because with Conditional attribute your code is still compiled.

Flash still has the ASO file, which is the compiled byte code for your classes. On Windows, you can see the ASO files here:

C:\Documents and Settings\username\Local Settings\Application Data\Adobe\Flash CS4\en\Configuration\Classes\aso

On a Mac, the directory structure is similar in /Users/username/Library/Application Support/

You can remove those files by hand, or in Flash you can select Control->Delete ASO files to remove them.

Based on the previous answers, I have created a context manager which protects from sigint and sigterm.

import logging
import signal
import sys


class TerminateProtected:
    """ Protect a piece of code from being killed by SIGINT or SIGTERM.
    It can still be killed by a force kill.

    Example:
        with TerminateProtected():
            run_func_1()
            run_func_2()

    Both functions will be executed even if a sigterm or sigkill has been received.
    """
    killed = False

    def _handler(self, signum, frame):
        logging.error("Received SIGINT or SIGTERM! Finishing this block, then exiting.")
        self.killed = True

    def __enter__(self):
        self.old_sigint = signal.signal(signal.SIGINT, self._handler)
        self.old_sigterm = signal.signal(signal.SIGTERM, self._handler)

    def __exit__(self, type, value, traceback):
        if self.killed:
            sys.exit(0)
        signal.signal(signal.SIGINT, self.old_sigint)
        signal.signal(signal.SIGTERM, self.old_sigterm)


if __name__ == '__main__':
    print("Try pressing ctrl+c while the sleep is running!")
    from time import sleep
    with TerminateProtected():
        sleep(10)
        print("Finished anyway!")
    print("This only prints if there was no sigint or sigterm")

Is there a way to PREVENT the browser scrolling to its past position, or to re-scroll to the top AFTER it does its thing?

The following jquery solution works for me:

$(window).unload(function() {
    $('body').scrollTop(0);
});

Make it Generic Swift 4

struct Matrix<T> {
    let rows: Int, columns: Int
    var grid: [T]
    init(rows: Int, columns: Int,defaultValue: T) {
        self.rows = rows
        self.columns = columns
        grid = Array(repeating: defaultValue, count: rows * columns) as! [T]
    }
    func indexIsValid(row: Int, column: Int) -> Bool {
        return row >= 0 && row < rows && column >= 0 && column < columns
    }
    subscript(row: Int, column: Int) -> T {
        get {
            assert(indexIsValid(row: row, column: column), "Index out of range")
            return grid[(row * columns) + column]
        }
        set {
            assert(indexIsValid(row: row, column: column), "Index out of range")
            grid[(row * columns) + column] = newValue
        }
    }
}


var matrix:Matrix<Bool> = Matrix(rows: 1000, columns: 1000,defaultValue:false)

matrix[0,10] = true


print(matrix[0,10])

Timer.Elapsed expects method of specific signature (with arguments object and EventArgs). If you want to use your PlayMusicEvent method with additional argument evaluated during event registration, you can use lambda expression as an adapter:

myTimer.Elapsed += new ElapsedEventHandler((sender, e) => PlayMusicEvent(sender, e, musicNote));

Edit: you can also use shorter version:

myTimer.Elapsed += (sender, e) => PlayMusicEvent(sender, e, musicNote);

str = "Tue, 10 Aug 2010 01:20:19 -0400 (EDT)"
str.to_date

Event.preventDefault- stops browser default behaviour. Now comes what is browser default behaviour. Assume you have a anchor tag and it has got a href attribute and this anchor tag is nested inside a div tag which has got a click event. Default behaviour of anchor tag is when clicked on the anchor tag it should navigate, but what event.preventDefault does is it stops the navigation in this case. But it never stops the bubbling of event or escalation of event i.e

<div class="container">
 <a href="#" class="element">Click Me!</a>
</div>

$('.container').on('click', function(e) {
 console.log('container was clicked');
});

$('.element').on('click', function(e) {
  e.preventDefault(); // Now link won't go anywhere
  console.log('element was clicked');
});

The result will be

"element was clicked"

"container was clicked"

Now event.StopPropation it stops bubbling of event or escalation of event. Now with above example

$('.container').on('click', function(e) {
  console.log('container was clicked');
});

$('.element').on('click', function(e) {
  e.preventDefault(); // Now link won't go anywhere
  e.stopPropagation(); // Now the event won't bubble up
 console.log('element was clicked');
});

Result will be

"element was clicked"

This Worked for me

Actually error is a array which contain error message and other values for elements we pass, you can console.log(error); and see. Inside if condition "error.appendTo($(element).parents('div').find($('.errorEmail')));" Is nothing but finding html element in code and passing the error message.

    $("form[name='contactUs']").validate({
rules: {
    message: 'required',
    name: "required",
    phone_number: {
        required: true,
        minlength: 10,
        maxlength: 10,
        number: false
    },
    email: {
        required: true,
        email: true
    }
},
messages: {
    name: "Please enter your name",
    email: "Please enter a valid email address",
    message: "Please enter your message",
    phone_number: "Please enter a valid mobile number"
},
errorPlacement: function(error, element) {
        $("#errorText").empty();

        if(error[0].htmlFor == 'name')
        {
            error.appendTo($(element).parents('div').find($('.errorName')));
        }
        if(error[0].htmlFor == 'email')
        {
            error.appendTo($(element).parents('div').find($('.errorEmail')));
        }
        if(error[0].htmlFor == 'phone_number')
        {
            error.appendTo($(element).parents('div').find($('.errorMobile')));
        }
        if(error[0].htmlFor == 'message')
        {
            error.appendTo($(element).parents('div').find($('.errorMessage')));
        }
      }
    });

For me installing the jdk 1.8 solved the issue.

Here's the best article in my opinion about running shell scripts in Ruby: "6 Ways to Run Shell Commands in Ruby".

If you only need to get the output use backticks.

I needed more advanced stuff like STDOUT and STDERR so I used the Open4 gem. You have all the methods explained there.

In my case, I did not copy all project files to the folder where I was running composer install. So do:

1. Copy your project files (including the composer.json) to folder
2. open CMD (I am using ConEmu), navigate to the new folder, run composer install from there
3. It should work or throw errors in case the json file is not correct.

If you just want to make composer run, create a new composer.json file with for example:

{
    "require": {
        "php": ">=5.3.2"
    }
}

Then run composer install.

Starting in v3.3 You can use updateMany

db.collection.updateMany(
   <filter>,
   <update>,
   {
     upsert: <boolean>,
     writeConcern: <document>,
     collation: <document>,
     arrayFilters: [ <filterdocument1>, ... ]
   }
)

In v2.2, the update function takes the following form:

 db.collection.update(
   <query>,
   <update>,
   { upsert: <boolean>, multi: <boolean> }
)

https://docs.mongodb.com/manual/reference/method/db.collection.update/

Try:

my_command || { echo 'my_command failed' ; exit 1; }

Four changes:

• Change && to ||
• Use { } in place of ( )
• Introduce ; after exit and
• spaces after { and before }

Since you want to print the message and exit only when the command fails ( exits with non-zero value) you need a || not an &&.

cmd1 && cmd2

will run cmd2 when cmd1 succeeds(exit value 0). Where as

cmd1 || cmd2

will run cmd2 when cmd1 fails(exit value non-zero).

Using ( ) makes the command inside them run in a sub-shell and calling a exit from there causes you to exit the sub-shell and not your original shell, hence execution continues in your original shell.

To overcome this use { }

The last two changes are required by bash.

 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //hide status bar
    requestWindowFeature( Window.FEATURE_NO_TITLE );
    getWindow().setFlags( WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN );


    setContentView(R.layout.activity_main);
}

You can use lambda functions in findAll as explained in documentation. So that in your case to search for td tag with only valign = "top" use following:

td_tag_list = soup.findAll(
                lambda tag:tag.name == "td" and
                len(tag.attrs) == 1 and
                tag["valign"] == "top")

You can use dictRysan library. I think that will solve your task.

import dictRysan as ry

d = { '123': { 'key1': 3, 'key2': 11, 'key3': 3 },
      '124': { 'key1': 6, 'key2': 56, 'key3': 6 },
      '125': { 'key1': 7, 'key2': 44, 'key3': 9 },
    }

changed_d=ry.nested_2L_value_sort(d,"key3",True)
print(changed_d)

Try this

$('#thisElement .classToSelect').each(function(i){
         // do stuff
});

Hope it will help

If you are using android studio use simple step

1. Run your project
2. Click on Gradle menu
3. Expand Gradle Tasks tree
4. Double click on android -> signingReport and see the magic
5. It will tell you everything on the Run tab

Result Under Run Tab If Android Studio < 2.2

From android studio 2.2
Result will be available under Run console but use highlighted toggle button

Or
Second Way is
Create new project in android studio New -> Google Maps Activity

then open google_maps_api.xml xml file as shown in pics you will see your SHA key

Use the .match() method to check whether String is UUID.

public boolean isUUID(String s){
    return s.match("^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$");
}

If you push for example image to some API and want the result address(response) back you could do:

import requests
url = 'https://uguu.se/api.php?d=upload-tool'
data = {"name": filename}
files = {'file': open(full_file_path, 'rb')}
response = requests.post(url, data=data, files=files)
current_url = response.text
print(response.text)

Eclipse likes lots of RAM. Use at least -Xmx512M. More if available.

While Migrating Android application package file (APK) to Android App Bundle (AAB), publishing app into Play Store i faced this issue and got resolved like this below...

When building .aab file you get prompted for the location to store key export path as below:

In second image you find Encrypted key export path Location where our .pepk will store in the specific folder while generating .aab file.

Once you log in to the Google Play Console with play store credential: select your project from left side choose App Signing option Release Management>>App Signing

you will find the Google App Signing Certification window ACCEPT it.

After that you will find three radio button select **

Upload a key exported from Android Studio radio button

**, it will expand you APP SIGNING PRIVATE KEY button as below

click on the button and choose the .pepk file (We Stored while generating .aab file as above)

Read the all other option and submit.

Once Successfully you can go back to app release and browse the .aab file and complete RollOut...

In this fiddle, I ran a test to demonstrate the blocking nature of await, as opposed to Promise.all which will start all of the promises and while one is waiting it will go on with the others.

Since it's an async operation the onreadystatechange may happen before the value has loaded in the responseText, try using a window.setTimeout(function () { JSON.parse(xhr.responseText); }, 1000); to see if the error persists? BOL

Rotating the labels is certainly possible. Note though that doing so reduces the readability of the text. One alternative is to alternate label positions using a code like this:

import numpy as np
n=5

x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Long ticklabel %i' % i for i in range(n)]


fig, ax = plt.subplots()
ax.plot(x,y, 'o-')
ax.set_xticks(x)
labels = ax.set_xticklabels(xlabels)
for i, label in enumerate(labels):

Intention of ConstraintLayout is to optimize and flatten the view hierarchy of your layouts by applying some rules to each view to avoid nesting.

Rules remind you of RelativeLayout, for example setting the left to the left of some other view.

app:layout_constraintBottom_toBottomOf="@+id/view1"

Unlike RelativeLayout, ConstraintLayout offers bias value that is used to position a view in terms of 0% and 100% horizontal and vertical offset relative to the handles (marked with circle). These percentages (and fractions) offer seamless positioning of the view across different screen densities and sizes.

app:layout_constraintHorizontal_bias="0.33" <!-- from 0.0 to 1.0 -->
app:layout_constraintVertical_bias="0.53" <!-- from 0.0 to 1.0 -->

Baseline handle (long pipe with rounded corners, below the circle handle) is used to align content of the view with another view reference.

Square handles (on each corner of the view) are used to resize the view in dps.

This is totally opinion based and my impression of ConstraintLayout

NOTE, I dont recommend this :). Here's a "oneliner" as well:

//This code generates numbers between 1 - 100 and then takes 10 of them.
var result = Enumerable.Range(1,101).OrderBy(g => Guid.NewGuid()).Take(10).ToArray();

Maybe this can help you resolve without JavaScript http://htmlhelp.com/reference/html40/forms/option.html

See DISABLE option

It's called designated initializer which is introduced in C99. It's used to initialize struct or arrays, in this example, struct.

Given

struct point { 
    int x, y;
};

the following initialization

struct point p = { .y = 2, .x = 1 };

is equivalent to the C89-style

struct point p = { 1, 2 };

REST means working with the standards of the web, and the standard for "secure" transfer on the web is SSL. Anything else is going to be kind of funky and require extra deployment effort for clients, which will have to have encryption libraries available.

Once you commit to SSL, there's really nothing fancy required for authentication in principle. You can again go with web standards and use HTTP Basic auth (username and secret token sent along with each request) as it's much simpler than an elaborate signing protocol, and still effective in the context of a secure connection. You just need to be sure the password never goes over plain text; so if the password is ever received over a plain text connection, you might even disable the password and mail the developer. You should also ensure the credentials aren't logged anywhere upon receipt, just as you wouldn't log a regular password.

HTTP Digest is a safer approach as it prevents the secret token being passed along; instead, it's a hash the server can verify on the other end. Though it may be overkill for less sensitive applications if you've taken the precautions mentioned above. After all, the user's password is already transmitted in plain-text when they log in (unless you're doing some fancy JavaScript encryption in the browser), and likewise their cookies on each request.

Note that with APIs, it's better for the client to be passing tokens - randomly generated strings - instead of the password the developer logs into the website with. So the developer should be able to log into your site and generate new tokens that can be used for API verification.

The main reason to use a token is that it can be replaced if it's compromised, whereas if the password is compromised, the owner could log into the developer's account and do anything they want with it. A further advantage of tokens is you can issue multiple tokens to the same developers. Perhaps because they have multiple apps or because they want tokens with different access levels.

(Updated to cover implications of making the connection SSL-only.)

As of now it is better to use SwitchCompat from the AppCompat.v7 library. You can then use simple styling to change the color of your components.

values/themes.xml:

<style name="Theme.MyTheme" parent="Theme.AppCompat.Light">
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">@color/my_awesome_color</item>

    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/my_awesome_darker_color</item>

    <!-- colorAccent is used as the default value for colorControlActivated,
         which is used to tint widgets -->
    <item name="colorAccent">@color/accent</item>

    <!-- You can also set colorControlNormal, colorControlActivated
         colorControlHighlight, and colorSwitchThumbNormal. -->

</style>

EDIT:

The way in which it should be correctly applied is through android:theme="@style/Theme.MyTheme" and also this can be applied to parent styles such as EditTexts, RadioButtons, Switches, CheckBoxes and ProgressBars:

<style name="My.Widget.ProgressBar" parent="Widget.AppCompat.ProgressBar">

<style name="My.Widget.Checkbox" parent="Widget.AppCompat.CompoundButton.CheckBox">

   SELECT CONVERT(varchar(11),getdate(),101)  -- mm/dd/yyyy

   SELECT CONVERT(varchar(11),getdate(),103)  -- dd/mm/yyyy

Check this . I am assuming D30.SPGD30_TRACKED_ADJUSTMENT_X is of datetime datatype .
That is why i am using CAST() function to make it as an character expression because CHARINDEX() works on character expression.
Also I think there is no need of OR condition.

select case when CHARINDEX('-',cast(D30.SPGD30_TRACKED_ADJUSTMENT_X as varchar )) > 0 

then 'Score Calculation - '+CONVERT(VARCHAR(11), D30.SPGD30_TRACKED_ADJUSTMENT_X, 103)
end

EDIT:

select case when CHARINDEX('-',D30.SPGD30_TRACKED_ADJUSTMENT_X) > 0 
then 'Score Calculation - '+
CONVERT( VARCHAR(11), CAST(D30.SPGD30_TRACKED_ADJUSTMENT_X as DATETIME) , 103)
end

A C++17 solution: full type safety + nice calling syntax

Since the introduction of variadic templates in C++11 and fold expressions in C++17, it is possible to define a template-function which, at the caller site, is callable as if it was a varidic function but with the advantages to:

• be strongly type safe;
• work without the run-time information of the number of arguments, or without the usage of a "stop" argument.

Here is an example for mixed argument types

template<class... Args>
void print(Args... args)
{
    (std::cout << ... << args) << "\n";
}
print(1, ':', " Hello", ',', " ", "World!");

And another with enforced type match for all arguments:

#include <type_traits> // enable_if, conjuction

template<class Head, class... Tail>
using are_same = std::conjunction<std::is_same<Head, Tail>...>;

template<class Head, class... Tail, class = std::enable_if_t<are_same<Head, Tail...>::value, void>>
void print_same_type(Head head, Tail... tail)
{
    std::cout << head;
    (std::cout << ... << tail) << "\n";
}
print_same_type("2: ", "Hello, ", "World!");   // OK
print_same_type(3, ": ", "Hello, ", "World!"); // no matching function for call to 'print_same_type(int, const char [3], const char [8], const char [7])'
                                               // print_same_type(3, ": ", "Hello, ", "World!");
                                                                                              ^

If you are using typescript and getting an error after installing all node modules then remove package-lock.json. And then run npm install.

The less complicated answer is to use .contents() to get at the iframe. Interestingly, though, it returns a different value from what I get using the code in my original answer, due to the padding on the body, I believe.

$('iframe').contents().height() + 'is the height'

This is how I've done it for cross-domain communication, so I'm afraid it's maybe unnecessarily complicated. First, I would put jQuery inside the iFrame's document; this will consume more memory, but it shouldn't increase load time as the script only needs to be loaded once.

Use the iFrame's jQuery to measure the height of your iframe's body as early as possible (onDOMReady) and then set the URL hash to that height. And in the parent document, add an onload event to the iFrame tag that will look at the location of the iframe and extract the value you need. Because onDOMReady will always occur before the document's load event, you can be fairly certain the value will get communicated correctly without a race condition complicating things.

In other words:

...in Help.php:

var getDocumentHeight = function() {
    if (location.hash === '') { // EDIT: this should prevent the retriggering of onDOMReady
        location.hash = $('body').height(); 
        // at this point the document address will be something like help.php#1552
    }
};
$(getDocumentHeight);

...and in the parent document:

var getIFrameHeight = function() {
    var iFrame = $('iframe')[0]; // this will return the DOM element
    var strHash = iFrame.contentDocument.location.hash;
    alert(strHash); // will return something like '#1552'
};
$('iframe').bind('load', getIFrameHeight );

KISS answer

Difference:

START_STICKY

the system will try to re-create your service after it is killed

START_NOT_STICKY

the system will not try to re-create your service after it is killed

Standard example:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    return START_STICKY;
}

Swift is statically typed so the performSelector: methods are to fall by the wayside.

Instead, use GCD to dispatch a suitable block to the relevant queue — in this case it'll presumably be the main queue since it looks like you're doing UIKit work.

EDIT: the relevant performSelector: is also notably missing from the Swift version of the NSRunLoop documentation ("1 Objective-C symbol hidden") so you can't jump straight in with that. With that and its absence from the Swiftified NSObject I'd argue it's pretty clear what Apple is thinking here.

Steveha's answer was helpful to me, but omits an important point (one that I think wisty was getting at). The global keyword is not necessary if you only access but do not assign the variable in the function.

If you assign the variable without the global keyword then Python creates a new local var -- the module variable's value will now be hidden inside the function. Use the global keyword to assign the module var inside a function.

Pylint 1.3.1 under Python 2.7 enforces NOT using global if you don't assign the var.

module_var = '/dev/hello'

def readonly_access():
    connect(module_var)

def readwrite_access():
    global module_var
    module_var = '/dev/hello2'
    connect(module_var)

For getting the element in react you need to use ref and inside the function you can use the ReactDOM.findDOMNode method.

But what I like to do more is to call the ref right inside the event

<input type="text" ref={ref => this.myTextInput = ref} />

This is some good link to help you figure out.

Use Range("A1").Text instead of .Value

post comment edit:
Why?
Because the .Text property of Range object returns what is literally visible in the spreadsheet, so if you cell displays for example i100l:25he*_92 then <- Text will return exactly what it in the cell including any formatting.
The .Value and .Value2 properties return what's stored in the cell under the hood excluding formatting. Specially .Value2 for date types, it will return the decimal representation.

If you want to dig deeper into the meaning and performance, I just found this article which seems like a good guide

another edit
Here you go @Santosh
type in (MANUALLY) the values from the DEFAULT (col A) to other columns
Do not format column A at all
Format column B as Text
Format column C as Date[dd/mm/yyyy]
Format column D as Percentage

now,
paste this code in a module

Sub main()

    Dim ws As Worksheet, i&, j&
    Set ws = Sheets(1)
    For i = 3 To 7
        For j = 1 To 4
            Debug.Print _
                    "row " & i & vbTab & vbTab & _
                    Cells(i, j).Text & vbTab & _
                    Cells(i, j).Value & vbTab & _
                    Cells(i, j).Value2
        Next j
    Next i
End Sub

and Analyse the output! Its really easy and there isn't much more i can do to help :)

A CGI script is a console/shell program. In Windows, when you use a "Command Prompt" window, you execute console programs. When a web server executes a CGI script it provides input to the console/shell program using environment variables or "standard input". Standard input is like typing data into a console/shell program; in the case of a CGI script, the web server does the typing. The CGI script writes data out to "standard output" and that output is sent to the client (the web browser) as a HTML page. Standard output is like the output you see in a console/shell program except the web server reads it and sends it out.

A CGI script can be executed from a browser. The URI typically includes a query string that is provided to the CGI script. If the method is "get" then the query string is provided to the CGI Script in an environment variable called QUERY_STRING. If the method is "post" then the query string is provided to the CGI Script using standard input (the CGI Script reads the query string from standard input).

An early use of CGI scripts was to process forms. In the beginning of HTML, HTML forms typically had an "action" attribute and a button designated as the "submit" button. When the submit button is pushed the URI specified in the "action" attribute would be sent to the server with the data from the form sent as a query string. If the "action" specifies a CGI script then the CGI script would be executed and it then produces a HTML page.

RFC 3875 "The Common Gateway Interface (CGI)" partially defines CGI using C, as in saying that environment variables "are accessed by the C library routine getenv() or variable environ".

If you are developing a CGI script using C/C++ and use Microsoft Visual Studio to do that then you would develop a console program.

ssize_t is used for functions whose return value could either be a valid size, or a negative value to indicate an error. It is guaranteed to be able to store values at least in the range [-1, SSIZE_MAX] (SSIZE_MAX is system-dependent).

So you should use size_t whenever you mean to return a size in bytes, and ssize_t whenever you would return either a size in bytes or a (negative) error value.

See: http://pubs.opengroup.org/onlinepubs/007908775/xsh/systypes.h.html

The return type of a lambda (in C++11) can be deduced, but only when there is exactly one statement, and that statement is a return statement that returns an expression (an initializer list is not an expression, for example). If you have a multi-statement lambda, then the return type is assumed to be void.

Therefore, you should do this:

  remove_if(rawLines.begin(), rawLines.end(), [&expression, &start, &end, &what, &flags](const string& line) -> bool
  {
    start = line.begin();
    end = line.end();
    bool temp = boost::regex_search(start, end, what, expression, flags);
    return temp;
  })

But really, your second expression is a lot more readable.

Extend TextView and override onDraw with the code below. It will keep text aspect ratio but size it to fill the space. You could easily modify code to stretch if necessary.

  @Override
  protected void onDraw(@NonNull Canvas canvas) {
    TextPaint textPaint = getPaint();
    textPaint.setColor(getCurrentTextColor());
    textPaint.setTextAlign(Paint.Align.CENTER);
    textPaint.drawableState = getDrawableState();

    String text = getText().toString();
    float desiredWidth = getMeasuredWidth() - getPaddingLeft() - getPaddingRight() - 2;
    float desiredHeight = getMeasuredHeight() - getPaddingTop() - getPaddingBottom() - 2;
    float textSize = textPaint.getTextSize();

    for (int i = 0; i < 10; i++) {
      textPaint.getTextBounds(text, 0, text.length(), rect);
      float width = rect.width();
      float height = rect.height();

      float deltaWidth = width - desiredWidth;
      float deltaHeight = height - desiredHeight;

      boolean fitsWidth = deltaWidth <= 0;
      boolean fitsHeight = deltaHeight <= 0;

      if ((fitsWidth && Math.abs(deltaHeight) < 1.0)
          || (fitsHeight && Math.abs(deltaWidth) < 1.0)) {
        // close enough
        break;
      }

      float adjustX = desiredWidth / width;
      float adjustY = desiredHeight / height;

      textSize = textSize * (adjustY < adjustX ? adjustY : adjustX);

      // adjust text size
      textPaint.setTextSize(textSize);
    }
    float x = desiredWidth / 2f;
    float y = desiredHeight / 2f - rect.top - rect.height() / 2f;
    canvas.drawText(text, x, y, textPaint);
  }

There are many ways to address your problem.

1. First one as accepted answer by @robert. Here is the generalised solution for it:

def multi_dimensional_list(value, *args):
  #args dimensions as many you like. EG: [*args = 4,3,2 => x=4, y=3, z=2]
  #value can only be of immutable type. So, don't pass a list here. Acceptable value = 0, -1, 'X', etc.
  if len(args) > 1:
    return [ multi_dimensional_list(value, *args[1:]) for col in range(args[0])]
  elif len(args) == 1: #base case of recursion
    return [ value for col in range(args[0])]
  else: #edge case when no values of dimensions is specified.
    return None

Eg:

>>> multi_dimensional_list(-1, 3, 4)  #2D list
[[-1, -1, -1, -1], [-1, -1, -1, -1], [-1, -1, -1, -1]]
>>> multi_dimensional_list(-1, 4, 3, 2)  #3D list
[[[-1, -1], [-1, -1], [-1, -1]], [[-1, -1], [-1, -1], [-1, -1]], [[-1, -1], [-1, -1], [-1, -1]], [[-1, -1], [-1, -1], [-1, -1]]]
>>> multi_dimensional_list(-1, 2, 3, 2, 2 )  #4D list
[[[[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]]], [[[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]]]]

P.S If you are keen to do validation for correct values for args i.e. only natural numbers, then you can write a wrapper function before calling this function.

2. Secondly, any multidimensional dimensional array can be written as single dimension array. This means you don't need a multidimensional array. Here are the function for indexes conversion:

def convert_single_to_multi(value, max_dim):
  dim_count = len(max_dim)
  values = [0]*dim_count
  for i in range(dim_count-1, -1, -1): #reverse iteration
    values[i] = value%max_dim[i]
    value /= max_dim[i]
  return values


def convert_multi_to_single(values, max_dim):
  dim_count = len(max_dim)
  value = 0
  length_of_dimension = 1
  for i in range(dim_count-1, -1, -1): #reverse iteration
    value += values[i]*length_of_dimension
    length_of_dimension *= max_dim[i]
  return value

Since, these functions are inverse of each other, here is the output:

>>> convert_single_to_multi(convert_multi_to_single([1,4,6,7],[23,45,32,14]),[23,45,32,14])
[1, 4, 6, 7]
>>> convert_multi_to_single(convert_single_to_multi(21343,[23,45,32,14]),[23,45,32,14])
21343

3. If you are concerned about performance issues then you can use some libraries like pandas, numpy, etc.

The Simple way is, to convert it to JSON String as below example:

Gson gson = new Gson();
String json = gson.toJson(myObj);

Then store the string in the shared preferences. Once you need it just get string from shared preferences and convert back to JSONArray or JSONObject(as per your requirement.)

To get the top five most common names:

dataframe['name'].value_counts().head()

This should do it:

[^a-zA-Z0-9]

Basically it matches all non-alphanumeric characters.

it's file:///android_asset/... not file:///android_assets/... notice the plural of assets is wrong even if your file name is assets

The answer from Constantin is spot on but for more background this behavior is inherited from Matlab.

The Matlab behavior is explained in the Figure Setup - Displaying Multiple Plots per Figure section of the Matlab documentation.

subplot(m,n,i) breaks the figure window into an m-by-n matrix of small subplots and selects the ithe subplot for the current plot. The plots are numbered along the top row of the figure window, then the second row, and so forth.

You could try this:

$in_str = 'this is a test';
$hex_ary = array();
foreach (str_split($in_str) as $chr) {
    $hex_ary[] = sprintf("%02X", ord($chr));
}
echo implode(' ',$hex_ary);

Here is how I would do it:

$("#target option")
    .removeAttr('selected')
    .find(':first')     // You can also use .find('[value=MyVal]')
        .attr('selected','selected');

If the XAMPP server is running for the moment, stop XAMPP server.

Follow these steps to change the port number.

Open the file in following location.

[XAMPP Installation Folder]/apache/conf/httpd.conf

Open the httpd.conf file and search for the String:

Listen 80

This is the port number used by XAMMP.

Then search for the string ServerName and update the Port Number which you entered earlier for Listen

Now save and re-start XAMPP server.

Code Snippet if you want to log your own

foreach(Environment.SpecialFolder f in Enum.GetValues(typeof(Environment.SpecialFolder)))
{
    string commonAppData = Environment.GetFolderPath(f);
    Console.WriteLine("{0}: {1}", f, commonAppData);
}
Console.ReadLine();

You've an number of options, depending on how you want to play it:

isNaN(val)

Returns true if val is not a number, false if it is. In your case, this is probably what you need.

isFinite(val)

Returns true if val, when cast to a String, is a number and it is not equal to +/- Infinity

/^\d+$/.test(val)

Returns true if val, when cast to a String, has only digits (probably not what you need).

The accepted answer which was triggering input event with jQuery didn't work for me. Creating an event and dispatching with native JavaScript did the trick.

$("input")[0].dispatchEvent(new Event("input", { bubbles: true }));

And another expansion:

# create dummy matrix
set.seed(10)
m <- matrix(round(runif(25, 1, 5)), 5)
d <- as.data.frame(m)

If you want to assign new column names you can do following on data.frame:

# an identical effect can be achieved with colnames()   
names(d) <- LETTERS[1:5]
> d
  A B C D E
1 3 2 4 3 4
2 2 2 3 1 3
3 3 2 1 2 4
4 4 3 3 3 2
5 1 3 2 4 3

If you, however run previous command on matrix, you'll mess things up:

names(m) <- LETTERS[1:5]
> m
     [,1] [,2] [,3] [,4] [,5]
[1,]    3    2    4    3    4
[2,]    2    2    3    1    3
[3,]    3    2    1    2    4
[4,]    4    3    3    3    2
[5,]    1    3    2    4    3
attr(,"names")
 [1] "A" "B" "C" "D" "E" NA  NA  NA  NA  NA  NA  NA  NA  NA  NA  NA  NA  NA  NA 
[20] NA  NA  NA  NA  NA  NA 

Since matrix can be regarded as two-dimensional vector, you'll assign names only to first five values (you don't want to do that, do you?). In this case, you should stick with colnames().

So there...

As DOC says, you can pass data to the handler as next:

// say your selector and click handler looks something like this...
$("some selector").on('click',{param1: "Hello", param2: "World"}, cool_function);

// in your function, just grab the event object and go crazy...
function cool_function(event){
    alert(event.data.param1);
    alert(event.data.param2);

    // access element's id where click occur
    alert( event.target.id ); 
}

I just had the same problem/question and solved it like this (only client code):

var io = io.connect('localhost');

io.on('connect', function () {
    console.log(this.socket.sessionid);
});

The alert() dialog is not rendered in HTML, and thus the HTML you have embedded is meaningless.

You'd need to use a custom modal to achieve that.

There's also an option to Auto Sync built-in in Aptana.

I believe that one of those will fit your need

1 - Undo commit and keep all files staged: git reset --soft HEAD~;

2 - Undo commit and unstage all files: git reset HEAD~;

3 - Undo the commit and completely remove all changes: git reset --hard HEAD~;

here is were I found the answer

I know this is an old topic, but I think it is still relevant, and would like to share an implementation of an array comparison method which I feel strikes the right balance between performance and elegance.

static bool CollectionEquals<T>(ICollection<T> a, ICollection<T> b, IEqualityComparer<T> comparer = null)
{
    return ReferenceEquals(a, b) || a != null && b != null && a.Count == b.Count && a.SequenceEqual(b, comparer);
}

The idea here is to check for all of the early out conditions first, then fall back on SequenceEqual. It also avoids doing extra branching and instead relies on boolean short-circuit to avoid unecessary execution. I also feel it looks clean and is easy to understand.

Also, by using ICollection for the parameters, it will work with more than just arrays.

Swift 3: You can create a UIButton programmatically

either inside a methods scope for example in ViewDidLoad() Be sure to add constraints to the button, otherwise you wont see it

let button = UIButton()
button.translatesAutoresizingMaskIntoConstraints = false
button.target(forAction: #selector(buttonAction), withSender: self)
//button.backgroundColor etc

view.addSubview(button)

@objc func buttonAction() {
   //some Action
}

or outside your scope as global variable to access it from anywhere in your module

let button: UIButton = {
   let b = UIButton()
   b.translatesAutoresizingMaskIntoConstraints = false
   //b.backgroundColor etc
   return b
}()

and then you setup the constraints

func setupButtonView() {
   view.addSubview(button)
   button.widthAnchor.constraint(equalToConstant: 40).isActive = true
   button.heightAnchor.constraint(equalToConstant: 40).isActive = true
   // etc

}

If you are using the Git Bash shell, you can use the following trick:

> webpage.html

This is actually the same as:

echo "" > webpage.html

Then, you can use git add webpage.html to stage the file.

Java 9

Optional.stream has been added to JDK 9. This enables you to do the following, without the need of any helper method:

Optional<Other> result =
    things.stream()
          .map(this::resolve)
          .flatMap(Optional::stream)
          .findFirst();

Java 8

Yes, this was a small hole in the API, in that it's somewhat inconvenient to turn an Optional<T> into a zero-or-one length Stream<T>. You could do this:

Optional<Other> result =
    things.stream()
          .map(this::resolve)
          .flatMap(o -> o.isPresent() ? Stream.of(o.get()) : Stream.empty())
          .findFirst();

Having the ternary operator inside the flatMap is a bit cumbersome, though, so it might be better to write a little helper function to do this:

/**
 * Turns an Optional<T> into a Stream<T> of length zero or one depending upon
 * whether a value is present.
 */
static <T> Stream<T> streamopt(Optional<T> opt) {
    if (opt.isPresent())
        return Stream.of(opt.get());
    else
        return Stream.empty();
}

Optional<Other> result =
    things.stream()
          .flatMap(t -> streamopt(resolve(t)))
          .findFirst();

Here, I've inlined the call to resolve() instead of having a separate map() operation, but this is a matter of taste.

In ReSharper 8: Tools -> Options -> ReSharper -> Suspend Now

As we recently posted on the React blog, in the vast majority of cases you don't need getDerivedStateFromProps at all.

If you just want to compute some derived data, either:

1. Do it right inside render
2. Or, if re-calculating it is expensive, use a memoization helper like memoize-one.

Here's the simplest "after" example:

import memoize from "memoize-one";

class ExampleComponent extends React.Component {
  getDerivedData = memoize(computeDerivedState);

  render() {
    const derivedData = this.getDerivedData(this.props.someValue);
    // ...
  }
}

About J Hardiman's answer, how about:

SELECT empName, projIDs=
  REPLACE(
    REPLACE(
      (SELECT REPLACE(projID, ' ', '-somebody-puts-microsoft-out-of-his-misery-please-') AS [data()] FROM project_members WHERE empName=a.empName FOR XML PATH('')), 
      ' ', 
      ' / '), 
    '-somebody-puts-microsoft-out-of-his-misery-please-',
    ' ') 
  FROM project_members a WHERE empName IS NOT NULL GROUP BY empName

By the way, is the use of "Surname" a typo or am i not understanding a concept here?

Anyway, thanks a lot guys cuz it saved me quite some time :)

The cleaner package has an na_replace() generic, that at default replaces numeric values with zeroes, logicals with FALSE, dates with today, etc.:

starwars %>% na_replace()
na_replace(starwars)

It even supports vectorised replacements:

mtcars[1:6, c("mpg", "hp")] <- NA
na_replace(mtcars, mpg, hp, replacement = c(999, 123))

Documentation: https://msberends.github.io/cleaner/reference/na_replace.html

If you want to pick columns from a ps output, any reason to not use -o?

e.g.

ps ax -o pid,vsz
ps ax -o pid,cmd

Minimum column width allocated, no padding, only single space field separator.

ps ax --no-headers -o pid:1,vsz:1,cmd

3443 24600 -bash
8419 0 [xfsalloc]
8420 0 [xfs_mru_cache]
8602 489316 /usr/sbin/apache2 -k start
12821 497240 /usr/sbin/apache2 -k start
12824 497132 /usr/sbin/apache2 -k start

Pid and vsz given 10 char width, 1 space field separator.

ps ax --no-headers -o pid:10,vsz:10,cmd

  3443      24600 -bash
  8419          0 [xfsalloc]
  8420          0 [xfs_mru_cache]
  8602     489316 /usr/sbin/apache2 -k start
 12821     497240 /usr/sbin/apache2 -k start
 12824     497132 /usr/sbin/apache2 -k start

Used in a script:-

oldpid=12824
echo "PID: ${oldpid}"
echo "Command: $(ps -ho cmd ${oldpid})"

arr1=[1,2,3]
arr2=[2,1,3]
ls=[arr2-arr1 for arr1,arr2 in zip(arr1,arr2)]
print(ls)
>>[1,-1,0]

It should usually work using the method Dave described in his answer. (I can confirm seeing "TextFX Characters" in the Available tab in Plugin Manager.)

If it does not, you can try downloading the zip file from here and put its contents (it's one file called NppTextFX.dll) inside the plugins folder where Notepad++ is installed. I suggest doing this while Notepad++ itself is not running.

You coud use your own custom AjaxExceptionHandler or primefaces-extensions

Update your faces-config.xml

...
<factory>
  <exception-handler-factory>org.primefaces.extensions.component.ajaxerrorhandler.AjaxExceptionHandlerFactory</exception-handler-factory>
</factory>
...

Add following code in your jsf page

...
<pe:ajaxErrorHandler />

Centos 7 php install comes with the ModSecurity package installed and enabled which prevents web access to phpMyAdmin. At the end of phpMyAdmin.conf, you should find

# This configuration prevents mod_security at phpMyAdmin directories from
# filtering SQL etc.  This may break your mod_security implementation.
#
#<IfModule mod_security.c>
#    <Directory /usr/share/phpMyAdmin/>
#        SecRuleInheritance Off
#    </Directory>
#</IfModule>

which gives you the answer to the problem. By adding

    SecRuleEngine Off

in the block "Directory /usr/share/phpMyAdmin/", you can solve the 'denied access' to phpmyadmin, but you may create security issues.

Calling the isHTML() method after the instance Body property (I mean $mail->Body) has been set solved the problem for me:

$mail->Subject = $Subject;
$mail->Body    = $Body;
$mail->IsHTML(true);       // <=== call IsHTML() after $mail->Body has been set.

In ST2 there's a package you can install called Default FileType which does just that.
