Using python-docx, as @Chinmoy Panda 's answer shows:

for para in doc.paragraphs:
    fullText.append(para.text)

However, para.text will lost the text in w:smarttag (Corresponding github issue is here: https://github.com/python-openxml/python-docx/issues/328), you should use the following function instead:

def para2text(p):
    rs = p._element.xpath('.//w:t')
    return u" ".join([r.text for r in rs])

Easy enough:

sudo aptitude install python3-pip
pip-3.2 install --user pkg

If you want Python 3.3, which isn't the default as of Ubuntu 12.10:

sudo aptitude install python3-pip python3.3
python3.3 -m pip.runner install --user pkg

you can try to put this in your php.ini:

ini_set("display_errors", "1");
error_reporting(E_ALL);

In php.ini file also you can set error_reporting();

You're accessing the latitude and longitude incorrectly.

Try

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">

var geocoder = new google.maps.Geocoder();
var address = "new york";

geocoder.geocode( { 'address': address}, function(results, status) {

  if (status == google.maps.GeocoderStatus.OK) {
    var latitude = results[0].geometry.location.lat();
    var longitude = results[0].geometry.location.lng();
    alert(latitude);
  } 
}); 
</script>

I hope the following code will solve your problem pretty well.

//Empty all tables' contents

$result_t = mysql_query("SHOW TABLES");
while($row = mysql_fetch_assoc($result_t))
{
mysql_query("TRUNCATE " . $row['Tables_in_' . $mysql_database]);
}
// Temporary variable, used to store current query
$templine = '';
// Read in entire file
$lines = file($filename);
// Loop through each line
foreach ($lines as $line)
{
// Skip it if it's a comment
if (substr($line, 0, 2) == '--' || $line == '')
    continue;

// Add this line to the current segment
$templine .= $line;
// If it has a semicolon at the end, it's the end of the query
if (substr(trim($line), -1, 1) == ';')
{
    // Perform the query
    mysql_query($templine) or print('Error performing query \'<strong>' . $templine . '\': ' . mysql_error() . '<br /><br />');
    // Reset temp variable to empty
    $templine = '';
}
}

Why and when you should mark the request parameter as implicit:

Some methods that you will make use of in the body of your action have an implicit parameter list like, for example, Form.scala defines a method:

def bindFromRequest()(implicit request: play.api.mvc.Request[_]): Form[T] = { ... }

You don't necessarily notice this as you would just call myForm.bindFromRequest() You don't have to provide the implicit arguments explicitly. No, you leave the compiler to look for any valid candidate object to pass in every time it comes across a method call that requires an instance of the request. Since you do have a request available, all you need to do is to mark it as implicit.

You explicitly mark it as available for implicit use.

You hint the compiler that it's "OK" to use the request object sent in by the Play framework (that we gave the name "request" but could have used just "r" or "req") wherever required, "on the sly".

myForm.bindFromRequest()

see it? it's not there, but it is there!

It just happens without your having to slot it in manually in every place it's needed (but you can pass it explicitly, if you so wish, no matter if it's marked implicit or not):

myForm.bindFromRequest()(request)

Without marking it as implicit, you would have to do the above. Marking it as implicit you don't have to.

When should you mark the request as implicit? You only really need to if you are making use of methods that declare an implicit parameter list expecting an instance of the Request. But to keep it simple, you could just get into the habit of marking the request implicit always. That way you can just write beautiful terse code.

Set the trigger option of the popover to hover instead of click, which is the default one.

This can be done using either data-* attributes in the markup:

<a id="popover" data-trigger="hover">Popover</a>

Or with an initialization option:

$("#popover").popover({ trigger: "hover" });

Here's a DEMO.

You could do:

select sum(counts) total_records from (
    select count(*) as counts
    from temptable
    group by column_1, column_2, column_3, column_4
) as tmp

none of answers helped me, in case when I had several levels of nested arrays. the solution is almost same as @AlienWebguy already did, but with tiny difference.

function nestedToSingle(array $array)
{
    $singleDimArray = [];

    foreach ($array as $item) {

        if (is_array($item)) {
            $singleDimArray = array_merge($singleDimArray, nestedToSingle($item));

        } else {
            $singleDimArray[] = $item;
        }
    }

    return $singleDimArray;
}

test example

$array = [
        'first',
        'second',
        [
            'third',
            'fourth',
        ],
        'fifth',
        [
            'sixth',
            [
                'seventh',
                'eighth',
                [
                    'ninth',
                    [
                        [
                            'tenth'
                        ]
                    ]
                ],
                'eleventh'
            ]
        ],
        'twelfth'
    ];

    $array = nestedToSingle($array);
    print_r($array);

    //output
    array:12 [
        0 => "first"
        1 => "second"
        2 => "third"
        3 => "fourth"
        4 => "fifth"
        5 => "sixth"
        6 => "seventh"
        7 => "eighth"
        8 => "ninth"
        9 => "tenth"
        10 => "eleventh"
        11 => "twelfth"
   ]

The answers above are still using the old Python 3.4 style coroutines. Here is what you would write if you got Python 3.5+.

aiohttp supports http proxy now

import aiohttp
import asyncio

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def main():
    urls = [
            'http://python.org',
            'https://google.com',
            'http://yifei.me'
        ]
    tasks = []
    async with aiohttp.ClientSession() as session:
        for url in urls:
            tasks.append(fetch(session, url))
        htmls = await asyncio.gather(*tasks)
        for html in htmls:
            print(html[:100])

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.

For me this problem was caused by a missing ) at the end of an if statement in a function called by the function the error was reported as from. Try scrolling up in the output to find the first error reported by the compiler. Fixing that error may fix this error.

Lock is a questionable idea in JS which is intended to be threadless and not needing concurrency protection. You're looking to combine calls on deferred execution. The pattern I follow for this is the use of callbacks. Something like this:

var functionLock = false;
var functionCallbacks = [];
var lockingFunction = function (callback) {
    if (functionLock) {
        functionCallbacks.push(callback);
    } else {
        $.longRunning(function(response) {
             while(functionCallbacks.length){
                 var thisCallback = functionCallbacks.pop();
                 thisCallback(response);
             }
        });
    }
}

You can also implement this using DOM event listeners or a pubsub solution.

Try this, edit the file with:

notepad foo.ps1:Zone.Identifier

And set 'ZoneId=0'

From the source code:

// Instance of WebViewClient that is the client callback.
private volatile WebViewClient mWebViewClient;
// Instance of WebChromeClient for handling all chrome functions.
private volatile WebChromeClient mWebChromeClient;

// SOME OTHER SUTFFF.......

/**
 * Set the WebViewClient.
 * @param client An implementation of WebViewClient.
 */
public void setWebViewClient(WebViewClient client) {
    mWebViewClient = client;
}

/**
 * Set the WebChromeClient.
 * @param client An implementation of WebChromeClient.
 */
public void setWebChromeClient(WebChromeClient client) {
    mWebChromeClient = client;
}

Using WebChromeClient allows you to handle Javascript dialogs, favicons, titles, and the progress. Take a look of this example: Adding alert() support to a WebView

At first glance, there are too many differences WebViewClient & WebChromeClient. But, basically: if you are developing a WebView that won't require too many features but rendering HTML, you can just use a WebViewClient. On the other hand, if you want to (for instance) load the favicon of the page you are rendering, you should use a WebChromeClient object and override the onReceivedIcon(WebView view, Bitmap icon).

Most of the times, if you don't want to worry about those things... you can just do this:

webView= (WebView) findViewById(R.id.webview); 
webView.setWebChromeClient(new WebChromeClient()); 
webView.setWebViewClient(new WebViewClient()); 
webView.getSettings().setJavaScriptEnabled(true); 
webView.loadUrl(url); 

And your WebView will (in theory) have all features implemented (as the android native browser).

For Centos 7 with php7.0

Install CentOS SCLo RH repository: yum install centos-release-scl-rh

Install rh-php71-php-bcmath rpm package: yum install rh-php71-php-bcmath

systemctl restart httpd.service

In my case i use $apply with angular calendar UI to link some event:

$scope.eventClick = function(event){           
    $scope.$apply( function() {
        $location.path('/event/' + event.id);
    });
};

After reading the doc of the problem: https://docs.angularjs.org/error/$rootScope/inprog

The part Inconsistent API (Sync/Async) is very interesting:

For example, imagine a 3rd party library that has a method which will retrieve data for us. Since it may be making an asynchronous call to a server, it accepts a callback function, which will be called when the data arrives.

Since, the MyController constructor is always instantiated from within an $apply call, our handler is trying to enter a new $apply block from within one.

I change the code to :

$scope.eventClick = function(event){           
    $timeout(function() {
        $location.path('/event/' + event.id);
    }, 0);
};

Works like a charm !

Here we have used $timeout to schedule the changes to the scope in a future call stack. By providing a timeout period of 0ms, this will occur as soon as possible and $timeout will ensure that the code will be called in a single $apply block.

git clone https://myusername:[email protected]/myusername/project.git

When you are trying to use private repo from the repo at the time you need to pass username and password for that.

This is a variation of n3rds solution above. No sorting by using ORDER BY is needed, as MIN() is used.

Remember that CustomerID (or whatever other numerical column you use for progress) must have a unique constraint. Furthermore, to make it as fast as possible CustomerID must be indexed on.

-- Declare & init
DECLARE @CustomerID INT = (SELECT MIN(CustomerID) FROM Sales.Customer); -- First ID
DECLARE @Data1 VARCHAR(200);
DECLARE @Data2 VARCHAR(200);

-- Iterate over all customers
WHILE @CustomerID IS NOT NULL
BEGIN  

  -- Get data based on ID
  SELECT @Data1 = Data1, @Data2 = Data2
    FROM Sales.Customer
    WHERE [ID] = @CustomerID ;

  -- call your sproc
  EXEC dbo.YOURSPROC @Data1, @Data2

  -- Get next customerId
  SELECT @CustomerID = MIN(CustomerID)
    FROM Sales.Customer
    WHERE CustomerID > @CustomerId 

END

I use this approach on some varchars I need to look over, by putting them in a temporary table first, to give them an ID.

Consider both at the same time:

• having singleton objects as static instances inside the classes.
• having a common class (Context) that returns the singleton instances for all the singelton objects in your application, which has the advantage that the method names in Context will be meaningful for example: context.getLoggedinUser() instead of User.getInstance().

Furthermore, I suggest that you expand your Context to include not only access to singleton objects but some functionalities that need to be accessed globally, like for example: context.logOffUser(), context.readSavedData(), etc. Probably renaming the Context to Facade would make sense then.

How do you read from stdin in Python?

I'm trying to do some of the code golf challenges, but they all require the input to be taken from stdin. How do I get that in Python?

You can use:

• sys.stdin - A file-like object - call sys.stdin.read() to read everything.
• input(prompt) - pass it an optional prompt to output, it reads from stdin up to the first newline, which it strips. You'd have to do this repeatedly to get more lines, at the end of the input it raises EOFError. (Probably not great for golfing.) In Python 2, this is rawinput(prompt).
• open(0).read() - In Python 3, the builtin function open accepts file descriptors (integers representing operating system IO resources), and 0 is the descriptor of stdin. It returns a file-like object like sys.stdin - probably your best bet for golfing. In Python 2, this is io.open.
• open('/dev/stdin').read() - similar to open(0), works on Python 2 and 3, but not on Windows (or even Cygwin).
• fileinput.input() - returns an iterator over lines in all files listed in sys.argv[1:], or stdin if not given. Use like ''.join(fileinput.input()).

Both sys and fileinput must be imported, respectively, of course.

Quick sys.stdin examples compatible with Python 2 and 3, Windows, Unix

You just need to read from sys.stdin, for example, if you pipe data to stdin:

$ echo foo | python -c "import sys; print(sys.stdin.read())"
foo

We can see that sys.stdin is in default text mode:

>>> import sys
>>> sys.stdin
<_io.TextIOWrapper name='<stdin>' mode='r' encoding='UTF-8'>

file example

Say you have a file, inputs.txt, we can accept that file and write it back out:

python -c "import sys; sys.stdout.write(sys.stdin.read())" < inputs.txt

Longer answer

Here's a complete, easily replicable demo, using two methods, the builtin function, input (use raw_input in Python 2), and sys.stdin. The data is unmodified, so the processing is a non-operation.

To begin with, let's create a file for inputs:

$ python -c "print('foo\nbar\nbaz')" > inputs.txt

And using the code we've already seen, we can check that we've created the file:

$ python -c "import sys; sys.stdout.write(sys.stdin.read())" < inputs.txt 
foo
bar
baz

Here's the help on sys.stdin.read from Python 3:

read(size=-1, /) method of _io.TextIOWrapper instance
    Read at most n characters from stream.
    
    Read from underlying buffer until we have n characters or we hit EOF.
    If n is negative or omitted, read until EOF.

Builtin function, input (raw_input in Python 2)

The builtin function input reads from standard input up to a newline, which is stripped (complementing print, which adds a newline by default.) This occurs until it gets EOF (End Of File), at which point it raises EOFError.

Thus, here's how you can use input in Python 3 (or raw_input in Python 2) to read from stdin - so we create a Python module we call stdindemo.py:

$ python -c "print('try:\n    while True:\n        print(input())\nexcept EOFError:\n    pass')" > stdindemo.py 

And let's print it back out to ensure it's as we expect:

$ python -c "import sys; sys.stdout.write(sys.stdin.read())" < stdindemo.py 
try:
    while True:
        print(input())
except EOFError:
    pass

Again, input reads up until the newline and essentially strips it from the line. print adds a newline. So while they both modify the input, their modifications cancel. (So they are essentially each other's complement.)

And when input gets the end-of-file character, it raises EOFError, which we ignore and then exit from the program.

And on Linux/Unix, we can pipe from cat:

$ cat inputs.txt | python -m stdindemo
foo
bar
baz

Or we can just redirect the file from stdin:

$ python -m stdindemo < inputs.txt 
foo
bar
baz

We can also execute the module as a script:

$ python stdindemo.py < inputs.txt 
foo
bar
baz

Here's the help on the builtin input from Python 3:

input(prompt=None, /)
    Read a string from standard input.  The trailing newline is stripped.
    
    The prompt string, if given, is printed to standard output without a
    trailing newline before reading input.
    
    If the user hits EOF (*nix: Ctrl-D, Windows: Ctrl-Z+Return), raise EOFError.
    On *nix systems, readline is used if available.

sys.stdin

Here we make a demo script using sys.stdin. The efficient way to iterate over a file-like object is to use the file-like object as an iterator. The complementary method to write to stdout from this input is to simply use sys.stdout.write:

$ python -c "print('import sys\nfor line in sys.stdin:\n    sys.stdout.write(line)')" > stdindemo2.py

Print it back out to make sure it looks right:

$ python -c "import sys; sys.stdout.write(sys.stdin.read())" < stdindemo2.py 
import sys
for line in sys.stdin:
    sys.stdout.write(line)

And redirecting the inputs into the file:

$ python -m stdindemo2 < inputs.txt
foo
bar
baz

Golfed into a command:

$ python -c "import sys; sys.stdout.write(sys.stdin.read())" < inputs.txt
foo
bar
baz

File Descriptors for Golfing

Since the file descriptors for stdin and stdout are 0 and 1 respectively, we can also pass those to open in Python 3 (not 2, and note that we still need the 'w' for writing to stdout).

If this works on your system, it will shave off more characters.

$ python -c "open(1,'w').write(open(0).read())" < inputs.txt
baz
bar
foo

Python 2's io.open does this as well, but the import takes a lot more space:

$ python -c "from io import open; open(1,'w').write(open(0).read())" < inputs.txt 
foo
bar
baz

Addressing other comments and answers

One comment suggests ''.join(sys.stdin) for golfing but that's actually longer than sys.stdin.read() - plus Python must create an extra list in memory (that's how str.join works when not given a list) - for contrast:

''.join(sys.stdin)
sys.stdin.read()

The top answer suggests:

import fileinput

for line in fileinput.input():
    pass

But, since sys.stdin implements the file API, including the iterator protocol, that's just the same as this:

import sys

for line in sys.stdin:
    pass

Another answer does suggest this. Just remember that if you do it in an interpreter, you'll need to do Ctrl-d if you're on Linux or Mac, or Ctrl-z on Windows (after Enter) to send the end-of-file character to the process. Also, that answer suggests print(line) - which adds a '\n' to the end - use print(line, end='') instead (if in Python 2, you'll need from __future__ import print_function).

The real use-case for fileinput is for reading in a series of files.

Lets see some simple examples of both __getattr__ and __getattribute__ magic methods.

__getattr__

Python will call __getattr__ method whenever you request an attribute that hasn't already been defined. In the following example my class Count has no __getattr__ method. Now in main when I try to access both obj1.mymin and obj1.mymax attributes everything works fine. But when I try to access obj1.mycurrent attribute -- Python gives me AttributeError: 'Count' object has no attribute 'mycurrent'

class Count():
    def __init__(self,mymin,mymax):
        self.mymin=mymin
        self.mymax=mymax

obj1 = Count(1,10)
print(obj1.mymin)
print(obj1.mymax)
print(obj1.mycurrent)  --> AttributeError: 'Count' object has no attribute 'mycurrent'

Now my class Count has __getattr__ method. Now when I try to access obj1.mycurrent attribute -- python returns me whatever I have implemented in my __getattr__ method. In my example whenever I try to call an attribute which doesn't exist, python creates that attribute and set it to integer value 0.

class Count:
    def __init__(self,mymin,mymax):
        self.mymin=mymin
        self.mymax=mymax    

    def __getattr__(self, item):
        self.__dict__[item]=0
        return 0

obj1 = Count(1,10)
print(obj1.mymin)
print(obj1.mymax)
print(obj1.mycurrent1)

__getattribute__

Now lets see the __getattribute__ method. If you have __getattribute__ method in your class, python invokes this method for every attribute regardless whether it exists or not. So why we need __getattribute__ method? One good reason is that you can prevent access to attributes and make them more secure as shown in the following example.

Whenever someone try to access my attributes that starts with substring 'cur' python raises AttributeError exception. Otherwise it returns that attribute.

class Count:

    def __init__(self,mymin,mymax):
        self.mymin=mymin
        self.mymax=mymax
        self.current=None

    def __getattribute__(self, item):
        if item.startswith('cur'):
            raise AttributeError
        return object.__getattribute__(self,item) 
        # or you can use ---return super().__getattribute__(item)

obj1 = Count(1,10)
print(obj1.mymin)
print(obj1.mymax)
print(obj1.current)

Important: In order to avoid infinite recursion in __getattribute__ method, its implementation should always call the base class method with the same name to access any attributes it needs. For example: object.__getattribute__(self, name) or super().__getattribute__(item) and not self.__dict__[item]

IMPORTANT

If your class contain both getattr and getattribute magic methods then __getattribute__ is called first. But if __getattribute__ raises AttributeError exception then the exception will be ignored and __getattr__ method will be invoked. See the following example:

class Count(object):

    def __init__(self,mymin,mymax):
        self.mymin=mymin
        self.mymax=mymax
        self.current=None

    def __getattr__(self, item):
            self.__dict__[item]=0
            return 0

    def __getattribute__(self, item):
        if item.startswith('cur'):
            raise AttributeError
        return object.__getattribute__(self,item)
        # or you can use ---return super().__getattribute__(item)
        # note this class subclass object

obj1 = Count(1,10)
print(obj1.mymin)
print(obj1.mymax)
print(obj1.current)

Use LIKE ANY(ARRAY['AAA%', 'BBB%', 'CCC%']) as per this cool trick @maniek showed earlier today.

In your mysql command line: SET explicit_defaults_for_timestamp=1

df2 <- data.frame(apply(df1, 2, function(x) as.numeric(as.character(x))))

If you want both to reference the same variable, one of them should have int k;, and the other should have extern int k;

For this situation, you typically put the definition (int k;) in one .cpp file, and put the declaration (extern int k;) in a header, to be included wherever you need access to that variable.

If you want each k to be a separate variable that just happen to have the same name, you can either mark them as static, like: static int k; (in all files, or at least all but one file). Alternatively, you can us an anonymous namespace:

namespace { 
   int k;
};

Again, in all but at most one of the files.

In C, the compiler generally isn't quite so picky about this. Specifically, C has a concept of a "tentative definition", so if you have something like int k; twice (in either the same or separate source files) each will be treated as a tentative definition, and there won't be a conflict between them. This can be a bit confusing, however, because you still can't have two definitions that both include initializers--a definition with an initializer is always a full definition, not a tentative definition. In other words, int k = 1; appearing twice would be an error, but int k; in one place and int k = 1; in another would not. In this case, the int k; would be treated as a tentative definition and the int k = 1; as a definition (and both refer to the same variable).

It might help you! Please see below steps.

• Put your SQL Script file(script.sql) in the documents folder.
• Type query with sqlcmd, server-name, database-name and script-file-name as like above highlighted query or below command line screen.

Actually, you can also do it with the iteration method. Because sometimes we might need to use the iteration method instead of the built-in epochs method to visualize the training results after each iteration.

history = [] #Creating a empty list for holding the loss later
for iteration in range(1, 3):
    print()
    print('-' * 50)
    print('Iteration', iteration)
    result = model.fit(X, y, batch_size=128, nb_epoch=1) #Obtaining the loss after each training
    history.append(result.history['loss']) #Now append the loss after the training to the list.
    start_index = random.randint(0, len(text) - maxlen - 1)
print(history)

This way allows you to get the loss you want while maintaining your iteration method.

This is a version of Ben James's answer, above:

>>> import datetime
>>> x = datetime.date.today()
>>> print x
2013-01-11
>>> 
>>> 
>>> print "Today's date is %s ..." % x
Today's date is 2013-01-11 ...
>>> 
>>> print "Today's date is %r ..." % x
Today's date is datetime.date(2013, 1, 11) ...
>>>

When I ran this, it helped me see the usefulness of %r.

If the latitude coordinate is reported as -6.3572375290155 or -63.572375290155 in decimal degrees then you could round-off and store up to 6 decimal places for 10 cm (or 0.1 meters) precision.

Overview

The valid range of latitude in degrees is -90 and +90 for the southern and northern hemisphere respectively. Longitude is in the range -180 and +180 specifying coordinates west and east of the Prime Meridian, respectively.

For reference, the Equator has a latitude of 0°, the North pole has a latitude of 90° north (written 90° N or +90°), and the South pole has a latitude of -90°.

The Prime Meridian has a longitude of 0° that goes through Greenwich, England. The International Date Line (IDL) roughly follows the 180° longitude. A longitude with a positive value falls in the eastern hemisphere and the negative value falls in the western hemisphere.

Decimal degrees precision

Six (6) decimal places precision in coordinates using decimal degrees notation is at a 10 cm (or 0.1 meters) resolution. Each .000001 difference in coordinate decimal degree is approximately 10 cm in length. For example, the imagery of Google Earth and Google Maps is typically at the 1-meter resolution, and some places have a higher resolution of 1 inch per pixel. One meter resolution can be represented using 5 decimal places so more than 6 decimal places are extraneous for that resolution. The distance between longitudes at the equator is the same as latitude, but the distance between longitudes reaches zero at the poles as the lines of meridian converge at that point.

For millimeter (mm) precision then represent lat/lon with 8 decimal places in decimal degrees format. Since most applications don't need that level of precision 6 decimal places is sufficient for most cases.

In the other direction, whole decimal degrees represent a distance of ~111 km (or 60 nautical miles) and a 0.1 decimal degree difference represents a ~11 km distance.

Here is a table of # decimal places difference in latitude with the delta degrees and the estimated distance in meters using 0,0 as the starting point.

Degrees-minute-second (DMS) representation

For DMS notation 1 arc second = 1/60/60 degree = ~30 meter length and 0.1 arc sec delta is ~3 meters.

Example:

• 0° 0' 0" W, 0° 0' 0" N ? 0° 0' 0" W, 0° 0' 1" N ? 30.715 meters
• 0° 0' 0" W, 0° 0' 0" N ? 0° 0' 0" W, 0° 0' 0.1" N ? 3.0715 meters

1 arc minute = 1/60 degree = ~2000m (2km)

Update:

Here is an amusing comic strip about coordinate precision.

Use its name() method:

public class Main {
    public static void main(String[] args) throws Exception {
        System.out.println(Strings.ONE.name());
    }
}

enum Strings {
    ONE, TWO, THREE
}

yields ONE.

You have to save that location somehow.

Say it's a POST form, just put the current location in a hidden field and then use it in the header() Location.

In your binding configuration, there are four timeout values you can tweak:

<bindings>
  <basicHttpBinding>
    <binding name="IncreasedTimeout"
             sendTimeout="00:25:00">
    </binding>
  </basicHttpBinding>

The most important is the sendTimeout, which says how long the client will wait for a response from your WCF service. You can specify hours:minutes:seconds in your settings - in my sample, I set the timeout to 25 minutes.

The openTimeout as the name implies is the amount of time you're willing to wait when you open the connection to your WCF service. Similarly, the closeTimeout is the amount of time when you close the connection (dispose the client proxy) that you'll wait before an exception is thrown.

The receiveTimeout is a bit like a mirror for the sendTimeout - while the send timeout is the amount of time you'll wait for a response from the server, the receiveTimeout is the amount of time you'll give you client to receive and process the response from the server.

In case you're send back and forth "normal" messages, both can be pretty short - especially the receiveTimeout, since receiving a SOAP message, decrypting, checking and deserializing it should take almost no time. The story is different with streaming - in that case, you might need more time on the client to actually complete the "download" of the stream you get back from the server.

There's also openTimeout, receiveTimeout, and closeTimeout. The MSDN docs on binding gives you more information on what these are for.

To get a serious grip on all the intricasies of WCF, I would strongly recommend you purchase the "Learning WCF" book by Michele Leroux Bustamante:

Learning WCF http://ecx.images-amazon.com/images/I/51GNuqUJq%2BL._BO2,204,203,200_PIsitb-sticker-arrow-click,TopRight,35,-76_AA240_SH20_OU01_.jpg

and you also spend some time watching her 15-part "WCF Top to Bottom" screencast series - highly recommended!

For more advanced topics I recommend that you check out Juwal Lowy's Programming WCF Services book.

Programming WCF http://ecx.images-amazon.com/images/I/41odWcLoGAL._BO2,204,203,200_PIsitb-sticker-arrow-click,TopRight,35,-76_AA240_SH20_OU01_.jpg

Some notes to complement the ALTER DATABASE process:

1) You can obtain a full list of databases with logical names and full paths of MDF and LDF files:

   USE master SELECT name, physical_name FROM sys.master_files

2) You can move manually the files with CMD move command:

Move "Source" "Destination"

Example:

md "D:\MSSQLData"
Move "C:\test\SYSADMIT-DB.mdf" "D:\MSSQLData\SYSADMIT-DB_Data.mdf"
Move "C:\test\SYSADMIT-DB_log.ldf" "D:\MSSQLData\SYSADMIT-DB_log.ldf"

3) You should change the default database path for new databases creation. The default path is obtained from the Windows registry.

You can also change with T-SQL, for example, to set default destination to: D:\MSSQLData

USE [master]

GO

EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultData', REG_SZ, N'D:\MSSQLData'

Just discovered GenMyModel, an awesome UML modeler to design class diagram online

I've a sample for multiple data with their subnode 3 list , each list has attribute and child attribute:

var list1 = {
    name: "Role A",
    name_selected: false,
    subs: [{
        sub: "Read",
        id: 1,
        selected: false
    }, {
        sub: "Write",
        id: 2,
        selected: false
    }, {
        sub: "Update",
        id: 3,
        selected: false
    }],
};
var list2 = {
    name: "Role B",
    name_selected: false,
    subs: [{
        sub: "Read",
        id: 1,
        selected: false
    }, {
        sub: "Write",
        id: 2,
        selected: false
    }],
};
var list3 = {
    name: "Role B",
    name_selected: false,
    subs: [{
        sub: "Read",
        id: 1,
        selected: false
    }, {
        sub: "Update",
        id: 3,
        selected: false
    }],
};

Add these to Array :

newArr.push(list1);
newArr.push(list2);
newArr.push(list3);
$scope.itemDisplayed = newArr;

Show them in html:

<li ng-repeat="item in itemDisplayed" class="ng-scope has-pretty-child">
    <div>
        <ul>
            <input type="checkbox" class="checkall" ng-model="item.name_selected" ng-click="toggleAll(item)" />
            <span>{{item.name}}</span>
            <div>
                <li ng-repeat="sub in item.subs" class="ng-scope has-pretty-child">
                    <input type="checkbox" kv-pretty-check="" ng-model="sub.selected" ng-change="optionToggled(item,item.subs)"><span>{{sub.sub}}</span>
                </li>
            </div>
        </ul>
    </div>
</li>

And here is the solution to check them:

$scope.toggleAll = function(item) {
    var toogleStatus = !item.name_selected;
    console.log(toogleStatus);
    angular.forEach(item, function() {
        angular.forEach(item.subs, function(sub) {
            sub.selected = toogleStatus;
        });
    });
};

$scope.optionToggled = function(item, subs) {
    item.name_selected = subs.every(function(itm) {
        return itm.selected;
    })
}

Depending on your PHP configuration, this may be a easy as using:

$jsonData = json_decode(file_get_contents('https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello|World&chof=json'));

However, if allow_url_fopen isn't enabled on your system, you could read the data via CURL as follows:

<?php
    $curlSession = curl_init();
    curl_setopt($curlSession, CURLOPT_URL, 'https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello|World&chof=json');
    curl_setopt($curlSession, CURLOPT_BINARYTRANSFER, true);
    curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, true);

    $jsonData = json_decode(curl_exec($curlSession));
    curl_close($curlSession);
?>

Incidentally, if you just want the raw JSON data, then simply remove the json_decode.

Please walk me through the commands I should run to figure this out.

The simplest test you can do is to perform 1000 requests, 10 at a time (which approximately simulates 10 concurrent users getting 100 pages each - over the length of the test).

ab -n 1000 -c 10 -k -H "Accept-Encoding: gzip, deflate" http://www.example.com/

-n 1000 is the number of requests to make.

-c 10 tells AB to do 10 requests at a time, instead of 1 request at a time, to better simulate concurrent visitors (vs. sequential visitors).

-k sends the KeepAlive header, which asks the web server to not shut down the connection after each request is done, but to instead keep reusing it.

I'm also sending the extra header Accept-Encoding: gzip, deflate because mod_deflate is almost always used to compress the text/html output 25%-75% - the effects of which should not be dismissed due to it's impact on the overall performance of the web server (i.e., can transfer 2x the data in the same amount of time, etc).

Multiply that by 60, and you have your requests per minute.

To get real world results, you'll want to test Wordpress instead of some static HTML or index.php file because you need to know how everything performs together: including complex PHP code, and multiple MySQL queries...

For example here is the results of testing a fresh install of Wordpress on the same system and WAMP environment (I'm using WampDeveloper, but there are also Xampp, WampServer, and others)...

Requests per second:    18.68 [#/sec] (mean)

That's 37x slower now!

After the load test, there are a number of things you can do to improve the overall performance (Requests Per Second), and also make the web server more stable under greater load (e.g., increasing the -n and the -c tends to crash Apache), that you can read about here:

Typically, git commit brings up an interactive editor (on Linux, and possibly Cygwin, determined by the contents of your $EDITOR environment variable) for you to edit your commit message in. When you save and exit, the commit completes.

You should make sure that the changes you are trying to commit have been added to the Git index; this determines what is committed. See http://gitref.org/basic/ for details on this.

__name__ changes depending on whether the code in question is run in the global namespace or as part of an imported module.

If the code is not running in the global space, __name__ will be the name of the module. If it is running in global namespace -- for example, if you type it into a console, or run the module as a script using python.exe yourscriptnamehere.py then __name__ becomes "__main__".

You'll see a lot of python code with if __name__ == '__main__' is used to test whether the code is being run from the global namespace – that allows you to have a module that doubles as a script.

Did you try to do these imports from the console?

1· Do I need these DLL's?

It depends since Dependency Walker is a little bit out of date and may report the wrong dependency.

2. Where can I get them?

most dlls can be found at https://www.dll-files.com

I believe they are supposed to located in C:\Windows\System32\Wer.dll and C:\Program Files\Internet Explorer\Ieshims.dll

For me leshims.dll can be placed at C:\Windows\System32\. Context: windows 7 64bit.

I know this is an old question, but I found a better solution with Vue.js 2.0+ Custom Directives: I needed to bind the scroll event too, then I implemented this.

First of, using @vue/cli, add the custom directive to src/main.js (before the Vue.js instance) or wherever you initiate it:

Vue.directive('scroll', {
  inserted: function(el, binding) {
    let f = function(evt) {
      if (binding.value(evt, el)) {
        window.removeEventListener('scroll', f);
      }
    }
    window.addEventListener('scroll', f);
  }
});

Then, add the custom v-scroll directive to the element and/or the component you want to bind on. Of course you have to insert a dedicated method: I used handleScroll in my example.

<my-component v-scroll="handleScroll"></my-component>

Last, add your method to the component.

methods: {
  handleScroll: function() {
    // your logic here
  }
}

You don’t have to care about the Vue.js lifecycle anymore here, because the custom directive itself does.

The Issue is the certificate request(CSR) was not generated from IIS. If you generated from Other sources e.g OpenSSL it will bring the issue. You need to generate the Certificate request(CSR) from IIS -> Create a certificate request, then enter all the details and then send to the vendor for regeneration of the SSL certificate. Mine worked properly after that.

The code pasted by Rivers is great. Thanks a lot! I'm new here and can't comment, I'd just want to answer to the question from javiervd (How would you set the screen_name and count with this approach?), as I've lost a lot of time to figure it out.

You need to add the parameters both to the URL and to the signature creating process. Creating a signature is the article that helped me. Here is my code:

$oauth = array(
           'screen_name' => 'DwightHoward',
           'count' => 2,
           'oauth_consumer_key' => $consumer_key,
           'oauth_nonce' => time(),
           'oauth_signature_method' => 'HMAC-SHA1',
           'oauth_token' => $oauth_access_token,
           'oauth_timestamp' => time(),
           'oauth_version' => '1.0'
         );

$options = array(
             CURLOPT_HTTPHEADER => $header,
             //CURLOPT_POSTFIELDS => $postfields,
             CURLOPT_HEADER => false,
             CURLOPT_URL => $url . '?screen_name=DwightHoward&count=2',
             CURLOPT_RETURNTRANSFER => true, CURLOPT_SSL_VERIFYPEER => false
           );

You can solve this problem by these Commands:

First:

sudo gem install cocoapods

Desp: type user mac password now your cocoapods will be replace with a stable version.

You can find out where the CocoaPods gem is installed with:

gem which cocoapods

if you have cloned the repo then type this command:

pod repo update

close your xcode and run this command

Pod install

I got into this state recently. After resolving conflicts during a rebase, I committed my changes, rather than running git rebase --continue. This yields the same messages you saw when you ran your git status and git rebase --continue commands. I resolved the issue by running git rebase --abort, and then re-running the rebase. One could likely also skip the rebase, but I wasn't sure what state that would leave me in.

$ git rebase --continue
Applying: <commit message>
No changes - did you forget to use 'git add'?
If there is nothing left to stage, chances are that something else
already introduced the same changes; you might want to skip this patch.

When you have resolved this problem, run "git rebase --continue".
If you prefer to skip this patch, run "git rebase --skip" instead.
To check out the original branch and stop rebasing, run "git rebase --abort".

$ git status

You are currently rebasing branch '<local-branch-name>' on '4df0775'.

edit: I just saw you meant in c#. Here is a better way with unmanaged code:

ManagementClass oMClass = new ManagementClass ("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection colMObj = oMCLass.GetInstances();
foreach(ManagementObject objMO in colMObj)
    Console.WriteLine(objMO["MacAddress"].ToString());

Starting Python 3.8, and the introduction of assignment expressions (PEP 572) (:= operator), which gives the possibility to name the result of an expression, we can use a list comprehension to replicate what other languages call fold/foldleft/reduce operations:

Given a list, a reducing function and an accumulator:

items = [1, 2, 3, 4, 5]
f = lambda acc, x: acc * x
accumulator = 1

we can fold items with f in order to obtain the resulting accumulation:

[accumulator := f(accumulator, x) for x in items]
# accumulator = 120

or in a condensed formed:

acc = 1; [acc := acc * x for x in [1, 2, 3, 4, 5]]
# acc = 120

Note that this is actually also a "scanleft" operation as the result of the list comprehension represents the state of the accumulation at each step:

acc = 1
scanned = [acc := acc * x for x in [1, 2, 3, 4, 5]]
# scanned = [1, 2, 6, 24, 120]
# acc = 120

You can use :visible for visible elements and :hidden to find out hidden elements. This hidden elements have display attribute set to none.

hiddenElements = $(':hidden');
visibleElements = $(':visible');

To check particular element.

if($('#yourID:visible').length == 0)
{

}

Elements are considered visible if they consume space in the document. Visible elements have a width or height that is greater than zero, Reference

You can also use is() with :visible

if(!$('#yourID').is(':visible'))
{

}

If you want to check value of display then you can use css()

if($('#yourID').css('display') == 'none')
{

}

If you are using display the following values display can have.

display: none

display: inline

display: block

display: list-item

display: inline-block

Check complete list of possible display values here.

To check the display property with JavaScript

var isVisible = document.getElementById("yourID").style.display == "block";
var isHidden = document.getElementById("yourID").style.display == "none"; 

In VueJS you can loop through an array like this : const array1 = ['a', 'b', 'c'];

Array.from(array1).forEach(element => 
 console.log(element)
      );

in my case I want to loop through files and add their types to another array:

 Array.from(files).forEach((file) => {
       if(this.mediaTypes.image.includes(file.type)) {
            this.media.images.push(file)
             console.log(this.media.images)
       }
   }

I have implement like this for multiple return value PHP function. be nice with your code. thank you.

 <?php
    function multi_retun($aa)
    {
        return array(1,3,$aa);
    }
    list($one,$two,$three)=multi_retun(55);
    echo $one;
    echo $two;
    echo $three;
    ?>

The first step is to run the emulator

emulator -avd < avd_name>

then use adb to install the .apk

adb install < path to .apk file>

If adb throws error like APK already exists or something alike. Run the adb shell while emulator is running

adb shell

cd data/app

adb uninstall < apk file without using .apk>

If adb and emulator are commands not found do following

export PATH=$PATH://android-sdk-macosx/platform-tools://android-sdk-macosx/android-sdk-macosx/tools:

For future use put the above line at the end of .bash_profile

vi ~/.bash_profile

    maxi = duplicates[el];
  }
});
console.log(max);

Note: As mentioned in comments below, this is an O(N) operation, so on a large DB with many keys you should not use this. For smaller deployments, it should be fine.

Support for Python 3 was added in NumPy version 1.5.0, so to begin with, you must download/install a newer version of NumPy.

If you are using jQuery in your project, or are willing to include it you can call nth-last-child through its selector API (this is this simulated it will cross browser). Here is a link to an nth-last-child plugin. If you took this method of targeting the elements you were interested in:

$('ul li:nth-last-child(1)').addClass('last');

And then style again the last class instead of the nth-child or nth-last-child pseudo selectors, you will have a much more consistent cross browser experience.

You can add

from functools import reduce

before you use the reduce.

FuzzyFinder has been mentioned, however I love the textmate like behaviour of the FuzzyFinderTextmate plugin which extends the behaviour to include all subdirs.

Make sure you are using version 2.16 of fuzzyfinder.vim - The higher versions break the plugin.

Parameter Options FollowSymLinks enables you to have a symlink in your webroot pointing to some other file/dir. With this disabled, Apache will refuse to follow such symlink. More secure Options SymLinksIfOwnerMatch can be used instead - this will allow you to link only to other files which you do own.

If you use Options directive in .htaccess with parameter which has been forbidden in main Apache config, server will return HTTP 500 error code.

Allowed .htaccess options are defined by directive AllowOverride in the main Apache config file. To allow symlinks, this directive need to be set to All or Options.

Besides allowing use of symlinks, this directive is also needed to enable mod_rewrite in .htaccess context. But for this, also the more secure SymLinksIfOwnerMatch option can be used.

Object destructuring the parameter object is what many of the answers above are aiming for and Typescript now has the methods in place to make it much easier to read and intuitively understand.

Destructuring Basics: By destructuring an object, you can choose properties from an object by key name. You can define as few or as many of the properties you like, and default values are set by a basic syntax of let {key = default} = object.

let {firstName, lastName = 'Smith'} = myParamsObject;

//Compiles to:
var firstName = myParamsObject.firstName, 
_a = myParamsObject.lastName, 
lastName = _a === void 0 ? 'Smith' : _a;

Writing an interface, type or class for the parameter object improves legibility.

type FullName = {_x000D_
  firstName: string;_x000D_
   _x000D_
  /** @default 'Smith' */_x000D_
  lastName ? : string;_x000D_
}_x000D_
_x000D_
function sayName(params: FullName) {_x000D_
_x000D_
  // Set defaults for parameter object_x000D_
  var { firstName, lastName = 'Smith'} = params;_x000D_
_x000D_
  // Do Stuff_x000D_
  var name = firstName + " " + lastName;_x000D_
  alert(name);_x000D_
}_x000D_
_x000D_
// Use it_x000D_
sayName({_x000D_
  firstName: 'Bob'_x000D_
});

With the dynamic keyword, it becomes really easy to parse any object of this kind:

dynamic x = Newtonsoft.Json.JsonConvert.DeserializeObject(jsonString);
var page = x.page;
var total_pages = x.total_pages
var albums = x.albums;
foreach(var album in albums)
{
    var albumName = album.name;

    // Access album data;
}

auto was a keyword that C++ "inherited" from C that had been there nearly forever, but virtually never used because there were only two possible conditions: either it wasn't allowed, or else it was assumed by default.

The use of auto to mean a deduced type was new with C++11.

At the same time, auto x = initializer deduces the type of x from the type of initializer the same way as template type deduction works for function templates. Consider a function template like this:

template<class T>
int whatever(T t) { 
    // point A
};

At point A, a type has been assigned to T based on the value passed for the parameter to whatever. When you do auto x = initializer;, the same type deduction is used to determine the type for x from the type of initializer that's used to initialize it.

This means that most of the type deduction mechanics a compiler needs to implement auto were already present and used for templates on any compiler that even sort of attempted to implement C++98/03. As such, adding support for auto was apparently fairly easy for essentially all the compiler teams--it was added quite quickly, and there seem to have been few bugs related to it either.

When this answer was originally written (in 2011, before the ink was dry on the C++ 11 standard) auto was already quite portable. Nowadays, it's thoroughly portable among all the mainstream compilers. The only obvious reasons to avoid it would be if you need to write code that's compatible with a C compiler, or you have a specific need to target some niche compiler that you know doesn't support it (e.g., a few people still write code for MS-DOS using compilers from Borland, Watcom, etc., that haven't seen significant upgrades in decades). If you're using a reasonably current version of any of the mainstream compilers, there's no reason to avoid it at all though.

For the updated question, you can replace what you want with something like:

someList = filter(lambda x: x not in ("a", "á", "à", "ã", "â"), someList)

filter evaluates every element of the list by passing it to the lambda provided. In this lambda we check if the element is not one of the characters provided, because these should stay in the list.

Alternatively, if the items in someList should be unique, you can make someList a set and do something like this:

someList = list(set(someList)-set(("a", "á", "à", "ã", "â")))

This essentially takes the difference between the sets, which does what you want, but also makes sure every element occurs only once, which is different from a list. Note you could store someList as a set from the beginning in this case, it will optimize things a bit.

For convenience, one may include tgmath.h library for the type generate macros. It creates the same function name as the double version for all type of variable. For example, For example, it defines a sqrt() macro that expands to the sqrtf() , sqrt() , or sqrtl() function, depending on the type of argument provided.

So one don't need to remember the corresponding function name for different type of variables!

#include <stdio.h>
#include <tgmath.h>//for the type generate macros. 
#include <complex.h>//for easier declare complex variables and complex unit I

int main(void)
{
    double complex z1=1./4.*M_PI+1./4.*M_PI*I;//M_PI is just pi=3.1415...
    double complex z2, z3, z4, z5; 

    z2=exp(z1);
    z3=sin(z1);
    z4=sqrt(z1);
    z5=log(z1);

    printf("exp(z1)=%lf + %lf I\n", creal(z2),cimag(z2));
    printf("sin(z1)=%lf + %lf I\n", creal(z3),cimag(z3));
    printf("sqrt(z1)=%lf + %lf I\n", creal(z4),cimag(z4));
    printf("log(z1)=%lf + %lf I\n", creal(z5),cimag(z5));

    return 0;
}

    Console.WriteLine("Enter your Date of Birth to Know your Current age in DD/MM/YY Format");
    string str = Console.ReadLine();
    DateTime dt1 = DateTime.Parse(str);
    DateTime dt2 = DateTime.Parse("10/06/2012");
    int result = (dt2 - dt1).Days;
    result = result / 365;
    Console.WriteLine("Your Current age is {0} years.",result);

I fix this problem using two clases, one similar to @jinshiyi11 answer's and the anoter is based on explicit click, in this you can click a button only once time, if you want another click you have to indicate it explicitly.

/**
 * Listener que sólo permite hacer click una vez, para poder hacer click
 * posteriormente se necesita indicar explicitamente.
 *
 * @author iberck
 */
public abstract class OnExplicitClickListener implements View.OnClickListener {

    // you can perform a click only once time
    private boolean canClick = true;

    @Override
    public synchronized void onClick(View v) {
        if (canClick) {
            canClick = false;
            onOneClick(v);
        }
    }

    public abstract void onOneClick(View v);

    public synchronized void enableClick() {
        canClick = true;
    }

    public synchronized void disableClick() {
        canClick = false;
    }
}

Example of use:

OnExplicitClickListener clickListener = new OnExplicitClickListener() {
    public void onOneClick(View v) {
        Log.d("example", "explicit click");
        ...
        clickListener.enableClick();    
    }
}
button.setOnClickListener(clickListener);

export class ClassComponent implements OnInit {
  classes = [
{
  name: 'string',
  level: 'string',
  code: 'number',
  currentLesson: '1'
}]


checkCurrentLession(current){

 this.classes.forEach((obj)=>{
    if(obj.currentLession == current){
      return true;
    }

  });
  return false;
}


<ul class="table lessonOverview">
        <li>
          <p>Lesson 1</p>
          <button [routerLink]="['/lesson1']" 
             [disabled]="checkCurrentLession(1)" class="primair">
               Start lesson</button>
        </li>
        <li>
          <p>Lesson 2</p>
          <button [routerLink]="['/lesson2']" 
             [disabled]="!checkCurrentLession(2)" class="primair">
               Start lesson</button>
        </li>
     </ul>

If accuracy is an issue here you can create random numbers with a finer graduation by randomizing the significant bits. Let's assume we want to have a double between 0.0 and 1000.0.

On MSVC (12 / Win32) RAND_MAX is 32767 for example.

If you use the common rand()/RAND_MAX scheme your gaps will be as large as

1.0 / 32767.0 * ( 1000.0 - 0.0) = 0.0305 ...

In case of IEE 754 double variables (53 significant bits) and 53 bit randomization the smallest possible randomization gap for the 0 to 1000 problem will be

2^-53 * (1000.0 - 0.0) = 1.110e-13

and therefore significantly lower.

The downside is that 4 rand() calls will be needed to obtain the randomized integral number (assuming a 15 bit RNG).

double random_range (double const range_min, double const range_max)
{
  static unsigned long long const mant_mask53(9007199254740991);
  static double const i_to_d53(1.0/9007199254740992.0);
  unsigned long long const r( (unsigned long long(rand()) | (unsigned long long(rand()) << 15) | (unsigned long long(rand()) << 30) | (unsigned long long(rand()) << 45)) & mant_mask53 );
  return range_min + i_to_d53*double(r)*(range_max-range_min);
}

If the number of bits for the mantissa or the RNG is unknown the respective values need to be obtained within the function.

#include <limits>
using namespace std;
double random_range_p (double const range_min, double const range_max)
{
  static unsigned long long const num_mant_bits(numeric_limits<double>::digits), ll_one(1), 
    mant_limit(ll_one << num_mant_bits);
  static double const i_to_d(1.0/double(mant_limit));
  static size_t num_rand_calls, rng_bits;
  if (num_rand_calls == 0 || rng_bits == 0)
  {
    size_t const rand_max(RAND_MAX), one(1);
    while (rand_max > (one << rng_bits))
    {
      ++rng_bits;
    }
    num_rand_calls = size_t(ceil(double(num_mant_bits)/double(rng_bits)));
  }
  unsigned long long r(0);
  for (size_t i=0; i<num_rand_calls; ++i)
  {
    r |= (unsigned long long(rand()) << (i*rng_bits));
  }
  r = r & (mant_limit-ll_one);
  return range_min + i_to_d*double(r)*(range_max-range_min);
}

Note: I don't know whether the number of bits for unsigned long long (64 bit) is greater than the number of double mantissa bits (53 bit for IEE 754) on all platforms or not. It would probably be "smart" to include a check like if (sizeof(unsigned long long)*8 > num_mant_bits) ... if this is not the case.

Try setting a Windows System Environment variable called _JAVA_OPTIONS with the heap size you want. Java should be able to find it and act accordingly.

i have solve my same problem

i update my android studio, and i choose not to import my setting from my previous version than that problem appear.

than i realize that i have 2 AndroidStudio folder on my windows account (.AndroidStudio and .AndroidStudio1.2) and on my new .AndroidStudio1.2 folder there are no other.xml file.

than i copy other.xml file from C:\Users\my windows account name.AndroidStudio\config\options to C:\Users\my windows account name.AndroidStudio1.2\config\options

and that how i solve my problem.

I read the answers. Then I noticed for me that the check box was already unchecked, but it still always reloaded the files. This is the Settings->Preferences->MISC->"Remember current session for next launch" check box on version 6.3.2. The following got rid of the problem:

1. Check the check box.
2. Exit the program.
3. Start the program again.
4. Uncheck the checkbox.

This function works for CRC-16 Modbus version. Not for CRC-16

It 'a permission problem when IIS is running I had this problem and I solved it in this way

I went on folders

C:\Windows\ System32\config\SystemProfile

and

C:\Windows\SysWOW64\config\SystemProfile

are protected system folders, they usually have the lock.

Right-click-> Card security-> Click on Edit-> Add untente "Autenticadet User" and assign permissions.

At this point everything is solved, if you still have problems try to give all permissions to "Everyone"

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

Getting an image into Jupyter NB is a much simpler operation than most people have alluded to here.

1) Simply create an empty Markdown cell. 2) Then drag-and-drop the image file into the empty Markdown cell.

The Markdown code that will insert the image then appears.

For example, a string shown highlighted in gray below will appear in the Jupyter cell:

![Venus_flytrap_taxonomy.jpg](attachment:Venus_flytrap_taxonomy.jpg)

3) Then execute the Markdown cell by hitting Shift-Enter. The Jupyter server will then insert the image, and the image will then appear.

I am running Jupyter notebook server is: 5.7.4 with Python 3.7.0 on Windows 7.

This is so simple !!

I know this has an accepted answer but if anyone comes upon this, my solution may help.

I found this question because I have a use-case where I wanted to turn off the :hover state for elements individually. Since there is no way to do this in the DOM, another good way to do it is to define a class in CSS that overrides the hover state.

For instance, the css:

.nohover:hover {
    color: black !important;
}

Then with jQuery:

$("#elm").addClass("nohover");

With this method, you can override as many DOM elements as you would like without binding tons of onHover events.

That would be:

b.rstrip('\n')

If you want to strip space from each and every line, you might consider instead:

a.read().splitlines()

This will give you a list of lines, without the line end characters.

This is essentially the algorithm you described as "clunky", using idiomatic pandas methods. Note the duplicate row indices. Also, note that this won't give you the expected output if df1 and df2 have no overlapping row indices, i.e., if

In [93]: df1.index & df2.index
Out[93]: Int64Index([], dtype='int64')

In fact, it won't give the expected output if their row indices are not equal.

As many suggested removing the <Target> tag may make it compile-able. Yet, beware of the fact that it has a side effect when you do it for test projects.

I got error related to MSTest.TestAdapter nuget package while compiling. Resolved that issue by removing <Target> tag. Though it made build successful, test methods became non discover-able. Test explorer won't list down the test methods in that project and Run Test or Debug Test won't work as well.

I encountered this while using Visual Studio 2017 and .Net framework 4.7, it can very well happen in other versions

The standard function atoi() will likely do what you want.

A simple example using "atoi":

#include <unistd.h>

int main(int argc, char *argv[])
{
    int useconds = atoi(argv[1]); 
    usleep(useconds);
}

It selects all elements where the class name contains the string "span" somewhere. There's also ^= for the beginning of a string, and $= for the end of a string. Here's a good reference for some CSS selectors.

I'm only familiar with the bootstrap classes spanX where X is an integer, but if there were other selectors that ended in span, it would also fall under these rules.

It just helps to apply blanket CSS rules.

Easy peasy:

var date = DateTime.Parse("14/11/2011"); // may need some Culture help here
Console.Write(date.ToString("yyyy-MM-dd"));

Take a look at DateTime.ToString() method, Custom Date and Time Format Strings and Standard Date and Time Format Strings

string customFormattedDateTimeString = DateTime.Now.ToString("yyyy-MM-dd");

To get a date string with milliseconds (3 decimal places behind seconds), use this:

from datetime import datetime

print datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S.%f')[:-3]

>>>> OUTPUT >>>>
2020-05-04 10:18:32.926

Note: For Python3, print requires parentheses:

print(datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S.%f')[:-3])

You could use the function trim

let str = ' Hello World ';

alert (str.trim());

All the front and back spaces around Hello World would be removed.

On Linux, I often use curl with the --head parameter. It is available for several operating systems, including Windows.

I have found a very easy way to Delete any folder(Even NOT Empty) or file on WINDOWS OS.

os.system('powershell.exe  rmdir -r D:\workspace\Branches\*%s* -Force' %CANDIDATE_BRANCH)

Technically there aren't actually any "remote" things at all¹ in your Git repo, there are just local names that should correspond to the names on another, different repo. The ones named origin/whatever will initially match up with those on the repo you cloned-from:

git clone ssh://some.where.out.there/some/path/to/repo # or git://some.where...

makes a local copy of the other repo. Along the way it notes all the branches that were there, and the commits those refer-to, and sticks those into your local repo under the names refs/remotes/origin/.

Depending on how long you go before you git fetch or equivalent to update "my copy of what's some.where.out.there", they may change their branches around, create new ones, and delete some. When you do your git fetch (or git pull which is really fetch plus merge), your repo will make copies of their new work and change all the refs/remotes/origin/<name> entries as needed. It's that moment of fetching that makes everything match up (well, that, and the initial clone, and some cases of pushing too—basically whenever Git gets a chance to check—but see caveat below).

Git normally has you refer to your own refs/heads/<name> as just <name>, and the remote ones as origin/<name>, and it all just works because it's obvious which one is which. It's sometimes possible to create your own branch names that make it not obvious, but don't worry about that until it happens. :-) Just give Git the shortest name that makes it obvious, and it will go from there: origin/master is "where master was over there last time I checked", and master is "where master is over here based on what I have been doing". Run git fetch to update Git on "where master is over there" as needed.

Caveat: in versions of Git older than 1.8.4, git fetch has some modes that don't update "where master is over there" (more precisely, modes that don't update any remote-tracking branches). Running git fetch origin, or git fetch --all, or even just git fetch, does update. Running git fetch origin master doesn't. Unfortunately, this "doesn't update" mode is triggered by ordinary git pull. (This is mainly just a minor annoyance and is fixed in Git 1.8.4 and later.)

¹Well, there is one thing that is called a "remote". But that's also local! The name origin is the thing Git calls "a remote". It's basically just a short name for the URL you used when you did the clone. It's also where the origin in origin/master comes from. The name origin/master is called a remote-tracking branch, which sometimes gets shortened to "remote branch", especially in older or more informal documentation.

I believe that there is some confusion here. The significant difference between cookie based authentication and what is now possible with HTML5 Web Storage is that browsers are built to send cookie data whenever they are requesting resources from the domain that set them. You can't prevent that without turning off cookies. Browsers do not send data from Web Storage unless code in the page sends it. And pages can only access data that they stored, not data stored by other pages.

So, a user worried about the way that their cookie data might be used by Google or Facebook might turn off cookies. But, they have less reason to turn off Web Storage (until the advertisers figure a way to use that as well).

So, that's the difference between cookie based and token based, the latter uses Web Storage.

Applets from what I remember do not need a main method, though I am not sure they are technically a program.

Pros

• Fixed-width layouts are much easier to use and easier to customize in terms of design.
• Widths are the same for every browser, so there is less hassle with images, forms, video and other content that are fixed-width.
• There is no need for min-width or max-width, which isn’t supported by every browser anyway.
• Even if a website is designed to be compatible with the smallest screen resolution, 800×600, the content will still be wide enough at a larger resolution to be easily legible.

Cons

• A fixed-width layout may create excessive white space for users with larger screen resolutions, thus upsetting “divine proportion,” the “Rule of Thirds,” overall balance and other design principles.
• Smaller screen resolutions may require a horizontal scroll bar, depending the fixed layout’s width.
• Seamless textures, patterns and image continuation are needed to accommodate those with larger resolutions.
• Fixed-width layouts generally have a lower overall score when it comes to usability.

From: https://requests.readthedocs.io/en/latest/user/quickstart/#post-a-multipart-encoded-file

Requests makes it very simple to upload Multipart-encoded files:

with open('report.xls', 'rb') as f:
    r = requests.post('http://httpbin.org/post', files={'report.xls': f})

That's it. I'm not joking - this is one line of code. The file was sent. Let's check:

>>> r.text
{
  "origin": "179.13.100.4",
  "files": {
    "report.xls": "<censored...binary...data>"
  },
  "form": {},
  "url": "http://httpbin.org/post",
  "args": {},
  "headers": {
    "Content-Length": "3196",
    "Accept-Encoding": "identity, deflate, compress, gzip",
    "Accept": "*/*",
    "User-Agent": "python-requests/0.8.0",
    "Host": "httpbin.org:80",
    "Content-Type": "multipart/form-data; boundary=127.0.0.1.502.21746.1321131593.786.1"
  },
  "data": ""
}

So, what's wrong with checking each element iteratively?

function arraysEqual(arr1, arr2) {
    if(arr1.length !== arr2.length)
        return false;
    for(var i = arr1.length; i--;) {
        if(arr1[i] !== arr2[i])
            return false;
    }

    return true;
}

• How would binding work for objects?
• How listening to change in the form might work?

An abstraction that updates both objects

I suppose there are other techniques, but ultimately I'd have an object that holds reference to a related DOM element, and provides an interface that coordinates updates to its own data and its related element.

The .addEventListener() provides a very nice interface for this. You can give it an object that implements the eventListener interface, and it'll invoke its handlers with that object as the this value.

This gives you automatic access to both the element and its related data.

Defining your object

Prototypal inheritance is a nice way to implement this, though not required of course. First you'd create a constructor that receives your element and some initial data.

function MyCtor(element, data) {
    this.data = data;
    this.element = element;
    element.value = data;
    element.addEventListener("change", this, false);
}

So here the constructor stores the element and data on properties of the new object. It also binds a change event to the given element. The interesting thing is that it passes the new object instead of a function as the second argument. But this alone won't work.

Implementing the eventListener interface

To make this work, your object needs to implement the eventListener interface. All that's needed to accomplish this is to give the object a handleEvent() method.

That's where the inheritance comes in.

MyCtor.prototype.handleEvent = function(event) {
    switch (event.type) {
        case "change": this.change(this.element.value);
    }
};

MyCtor.prototype.change = function(value) {
    this.data = value;
    this.element.value = value;
};

There are many different ways in which this could be structured, but for your example of coordinating updates, I decided to make the change() method only accept a value, and have the handleEvent pass that value instead of the event object. This way the change() can be invoked without an event as well.

So now, when the change event happens, it'll update both the element and the .data property. And the same will happen when you call .change() in your JavaScript program.

Using the code

Now you'd just create the new object, and let it perform updates. Updates in JS code will appear on the input, and change events on the input will be visible to the JS code.

var obj = new MyCtor(document.getElementById("foo"), "20");

// simulate some JS based changes.
var i = 0;
setInterval(function() {
    obj.change(parseInt(obj.element.value) + ++i);
}, 3000);

You can write the below code:-

create procedure spCreateTable
   as
    begin
       create table testtb(Name varchar(20))
    end

execute it as:-

exec spCreateTable

Your construction completely defeats the purpose of a generic method. It's ugly on purpose because there must be a better way to achieve what you're trying to accomplish, although you haven't given us quite enough information to figure out what that is.

Best solution so far that I have seen is in FastAdapter library for recycler views. It has a EndlessRecyclerOnScrollListener.

Here is an example usage: EndlessScrollListActivity

Once I used it for endless scrolling list I have realised that the setup is a very robust. I'd definitely recommend it.

The first parameter is the name of the script you want to run. From the second parameter onwards it is the the parameters that you want to pass from your command line. Below is a test script:

from sys import argv

script, first, second = argv
print "Script is ",script
print "first is ",first
print "second is ",second

And here is how you pass the input parameters : 'Path to your script','First Parameter','Second Parameter'

Lets say that the Path to your script is /home/my_folder/test.py , the output will be like :

Script is /home/my_folder/test.py
first is First Parameter
second is Second Parameter

Hope this helps as it took me sometime to figure out input parameters are comma separated.

You should be able to cite at least one from the JDK itself. Look in the java.util.collections package. There are several abstract classes. You should fully understand interface, abstract, and concrete for Map and why Joshua Bloch wrote it that way.

If you have an image imported as a resource in your project there is also this:

picPreview.Image = Properties.Resources.ImageName;

Where picPreview is the name of the picture box and ImageName is the name of the file you want to display.

*Resources are located by going to: Project --> Properties --> Resources

There is no portable way to read raw characters from a Java console.

Some platform-dependent workarounds have been presented above. But to be really portable, you'd have to abandon console mode and use a windowing mode, e.g. AWT or Swing.

first call the intent

Intent intenta = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
startActivityForResult(intenta, 42);

then call the result

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case 42:
            if (resultCode == Activity.RESULT_OK) {
                Uri sdCardUri = data.getData();
                DocumentFile pickedDir = DocumentFile.fromTreeUri(this, sdCardUri);
                for (DocumentFile file : pickedDir.listFiles()) {
                    String pp = file.getName();
                    if(pp.equals("VLC.apk"))
                        file.delete();
                    String ppdf="";
                }
                File pathFile = new File(String.valueOf(sdCardUri));
                pathFile.delete();
            }
            break;
    }
}

This is what I use to get the minimum date in SQL Server. Please note that it is globalisation friendly:

RETURNS datetime
AS
BEGIN
  RETURN (SELECT
    CAST('17530101' AS datetime))
END

Call using:

SELECT [dbo].[DateTimeMinValue]()

    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btn"
    android:onClick="onClickBtn" />

    public void onCreate(Bundle savedInstanceState) 
    {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);    
    }

    public void onClickBtn(View v)
    {
        Toast.makeText(this, "Clicked on Button", Toast.LENGTH_LONG).show();

 button.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
        // TODO Auto-generated method stub

    }

Quoting this link: http://steveswanson.wordpress.com/2009/04/21/exporting-and-importing-an-individual-mysql-table/

• Exporting the Table

To export the table run the following command from the command line:

mysqldump -p --user=username dbname tableName > tableName.sql

This will export the tableName to the file tableName.sql.

• Importing the Table

To import the table run the following command from the command line:

mysql -u username -p -D dbname < tableName.sql

The path to the tableName.sql needs to be prepended with the absolute path to that file. At this point the table will be imported into the DB.

Use $elemMatch to find the array of particular object

db.users.findOne({"_id": id},{awards: {$elemMatch: {award:'Turing Award', year:1977}}})

to upload a file using curl in Windows I found that the path requires escaped double quotes

e.g.

curl -v -F 'upload=@\"C:/myfile.txt\"' URL

php.ini probably needs to read: extension=ext\php_sqlsrv_53_nts.dll

Or move the file to same directory as the php executable. This is what I did to my php5 install this week to get odbc_pdo working. :P

Additionally, that doesn't look like proper phpinfo() output. If you make a file with contents
<? phpinfo(); ?> and visit that page, the HTML output should show several sections, including one with loaded modules. (Edited to add: like shown in the screenshot of the above accepted answer)

After struggling for a while I finally got this to work with eclipse.ini instead of the command line. After finally reading the documentation I realized that the -vm argument must be on a separate line, unquoted, and ahead of any -vmargs:

-vm
C:\Program Files\Java\jdk1.7.0_45\bin\javaw.exe

It's probably not what you want, but a tool like re2c can compile POSIX(-ish) regular expressions to ANSI C. It's written as a replacement for lex, but this approach allows you to sacrifice flexibility and legibility for the last bit of speed, if you really need it.

The problem you're running into is that you're trying to replace an entire row object. That is not allowed by the DataTable API. Instead you have to update the values in the columns of a row object. Or add a new row to the collection.

To update the column of a particular row you can access it by name or index. For instance you could write the following code to update the column "Foo" to be the value strVerse

dtResult.Rows(i)("Foo") = strVerse

Either of the latter two, since val could potentially be of a type that defines __eq__() to return true when passed None.

You can also change the date format for the session. This is useful, for example, in Perl DBI, where the to_date() function is not available:

ALTER SESSION SET NLS_DATE_FORMAT='YYYY-MM-DD'

You can permanently set the default nls_date_format as well:

ALTER SYSTEM SET NLS_DATE_FORMAT='YYYY-MM-DD'

In Perl DBI you can run these commands with the do() method:

$db->do("ALTER SESSION SET NLS_DATE_FORMAT='YYYY-MM-DD');

Python 3.7:

List comprehensions are faster.

Generators are more memory efficient.

As all others have said, if you're looking to scale infinite data, you'll need a generator eventually. For relatively static small and medium-sized jobs where speed is necessary, a list comprehension is best.

I realize this question was asked a long time ago, but I came here looking for answers and wasn't satisfied with anything I could find. I finally found the answer here:

https://www.tutorialsteacher.com/mvc/htmlhelper-dropdownlist-dropdownlistfor

To get the results from the form, use the FormCollection and then pull each individual value out by it's model name thus:

yourRecord.FieldName = Request.Form["FieldNameInModel"];

As far as I could tell it makes absolutely no difference what argument name you give to the FormCollection - use Request.Form["NameFromModel"] to retrieve it.

No, I did not dig down to see how th4e magic works under the covers. I just know it works...

I hope this helps somebody avoid the hours I spent trying different approaches before I got it working.

How about creating extension methods that allow you to add the parameters in a fluent style like this?

string a = "http://www.somedomain.com/somepage.html"
    .AddQueryParam("A", "TheValueOfA")
    .AddQueryParam("B", "TheValueOfB")
    .AddQueryParam("Z", "TheValueOfZ");

string b = new StringBuilder("http://www.somedomain.com/anotherpage.html")
    .AddQueryParam("A", "TheValueOfA")
    .AddQueryParam("B", "TheValueOfB")
    .AddQueryParam("Z", "TheValueOfZ")
    .ToString(); 

Here's the overload that uses a string:

public static string AddQueryParam(
    this string source, string key, string value)
{
    string delim;
    if ((source == null) || !source.Contains("?"))
    {
        delim = "?";
    }
    else if (source.EndsWith("?") || source.EndsWith("&"))
    {
        delim = string.Empty;
    }
    else
    {
        delim = "&";
    }

    return source + delim + HttpUtility.UrlEncode(key)
        + "=" + HttpUtility.UrlEncode(value);
}

And here's the overload that uses a StringBuilder:

public static StringBuilder AddQueryParam(
    this StringBuilder source, string key, string value)
{
    bool hasQuery = false;
    for (int i = 0; i < source.Length; i++)
    {
        if (source[i] == '?')
        {
            hasQuery = true;
            break;
        }
    }

    string delim;
    if (!hasQuery)
    {
        delim = "?";
    }
    else if ((source[source.Length - 1] == '?')
        || (source[source.Length - 1] == '&'))
    {
        delim = string.Empty;
    }
    else
    {
        delim = "&";
    }

    return source.Append(delim).Append(HttpUtility.UrlEncode(key))
        .Append("=").Append(HttpUtility.UrlEncode(value));
}

@ - Instance variable of a class
@@ - Class variable, also called as static variable in some cases

A class variable is a variable that is shared amongst all instances of a class. This means that only one variable value exists for all objects instantiated from this class. If one object instance changes the value of the variable, that new value will essentially change for all other object instances.

Another way of thinking of thinking of class variables is as global variables within the context of a single class. Class variables are declared by prefixing the variable name with two @ characters (@@). Class variables must be initialized at creation time

The ngRoute module is no longer part of the core angular.js file. If you are continuing to use $routeProvider then you will now need to include angular-route.js in your HTML:

<script src="angular.js">
<script src="angular-route.js">

API Reference

You also have to add ngRoute as a dependency for your application:

var app = angular.module('MyApp', ['ngRoute', ...]);

If instead you are planning on using angular-ui-router or the like then just remove the $routeProvider dependency from your module .config() and substitute it with the relevant provider of choice (e.g. $stateProvider). You would then use the ui.router dependency:

var app = angular.module('MyApp', ['ui.router', ...]);

span::before { content: "\A"; white-space: pre; }

You need J-query library to do this simply:

<script src="//code.jquery.com/jquery-1.11.3.min.js"></script>

First you need to put your element in div like this:

<div id="divClickHere">
<a id="a_tbnotesverbergen" href="#nothing">click here</a>
</div>

Then you should write this J-Query Code:

<script type="text/javascript">
$(document).ready(function(){
$("#a_tbnotesverbergen").click(function(){
$("#divClickHere a").text('Your new text');
});
});
</script>

Only for this situation -

Not checking if a variable is null before invoking an equals method (a string compare example below):

if ( foo.equals("bar") ) {
 // ...
}

will result in a NullPointerException if foo doesn't exist.

You can avoid that if you compare your Strings like this:

if ( "bar".equals(foo) ) {
 // ...
}

According to the examples base64 encoding is directly supported, although I've not tested it myself. Take your base64 string (derived from a file or loaded with any other method, POST/GET, websockets etc), turn it to a binary with atob, and then parse this to getDocument on the PDFJS API likePDFJS.getDocument({data: base64PdfData}); Codetoffel answer does work just fine for me though.

Couldn't you just create a record in a separate table or whatever with a column called Users and UPDATE it with the last inserted id on User Registration?

Then you would just check this field with a simple query.

It might be rough but it would work perfectly.

The tool that richardtz suggests is excellent.

Another one that is amazing and comes with a 30 day free trial is Araxis Merge. This one does a 3 way merge and is much more feature complete than winmerge, but it is a commercial product.

You might also like to check out Scott Hanselman's developer tool list, which mentions a couple more in addition to winmerge

in OpenCV 3.0 you can use it easily as follow:

#combine 2 images same as to concatenate images with two different sizes
h1, w1 = img1.shape[:2]
h2, w2 = img2.shape[:2]
#create empty martrix (Mat)
res = np.zeros(shape=(max(h1, h2), w1 + w2, 3), dtype=np.uint8)
# assign BGR values to concatenate images
for i in range(res.shape[2]):
    # assign img1 colors
    res[:h1, :w1, i] = np.ones([img1.shape[0], img1.shape[1]]) * img1[:, :, i]
    # assign img2 colors
    res[:h2, w1:w1 + w2, i] = np.ones([img2.shape[0], img2.shape[1]]) * img2[:, :, i]

output_img = res.astype('uint8')

For Select2 v4:

Use dropdownParent to attach the dropdown to the modal dialog, rather than the HTML body.

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        <select id="select2insidemodal" multiple="multiple">
          <option value="AL">Alabama</option>
            ...
          <option value="WY">Wyoming</option>
        </select>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>


<script>

$(document).ready(function() {
  $("#select2insidemodal").select2({
    dropdownParent: $("#myModal")
  });
});

</script>

This will attach the Select2 dropdown so it falls within the DOM of the modal rather than to the HTML body (the default). See https://select2.org/dropdown#dropdown-placement

Are these servers virtualized? On another post I've read about a SQL server running sometimes very slowly because of lack of sufficient memory. This in turn was caused by a so-called memory balloon that the virtualizer used to limit the amount of memory used by that virtual server. It was hard to find because the pressure on physical memory had nothing to do with the SQL server itself.

Another common cause for a temporary performance degradation might be a virus scanner. When a new virus definition is installed, all other processes will suffer and run very slow. Check out any other automatic update process, this might also take a lot of resources quite unexpectedly. Good luck with it!

It's safe to increase the size of your varchar column. You won't corrupt your data.

If it helps your peace of mind, keep in mind, you can always run a database backup before altering your data structures.

By the way, correct syntax is:

ALTER TABLE table_name MODIFY col_name VARCHAR(10000)

Also, if the column previously allowed/did not allow nulls, you should add the appropriate syntax to the end of the alter table statement, after the column type.

Your code is fine, but the problem is inside the batch file.

You have to show the content of the bat file, your problem is in the paths inside the bat file.

I would like to point out that TypeScript does not provide a direct mechanism for dynamically testing whether an object implements a particular interface.

Instead, TypeScript code can use the JavaScript technique of checking whether an appropriate set of members are present on the object. For example:

var obj : any = new Foo();

if (obj.someInterfaceMethod) {
    ...
}

If only two values are required to create the object with a valid state, you could simply remove all the other optional arguments and provide setters for them (unless you dont want them to changed at runtime). Then just instantiate the object with the two required arguments and set the others as needed through the setter.

Run "svn help commit" to all available options. You will see that there is one option responsible for accepting server certificates:

--trust-server-cert : accept unknown SSL server certificates without prompting (but only with --non-interactive)

Add it to your svn command arguments and you will not need to run svn manually to accept it permanently.

Easy way in kotlin

In your fragment

requireActivity().window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE or WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN)

Though it's an old post, the question keep coming up and the answers don't always seem clear to me, so, here's my thoughts:

%w and %W are examples of General Delimited Input types, that relate to Arrays. There are other types that include %q, %Q, %r, %x and %i.

The difference between the upper and lower case version is that it gives us access to the features of single and double quotes. With single quotes and (lowercase) %w, we have no code interpolation (#{someCode}) and a limited range of escape characters that work (\\, \n). With double quotes and (uppercase) %W we do have access to these features.

The delimiter used can be any character, not just the open parenthesis. Play with the examples above to see that in effect.

For a full write up with examples of %w and the full list, escape characters and delimiters, have a look at "Ruby - %w vs %W – secrets revealed!"

You need to have a look at Same Origin Policy:

In computing, the same origin policy is an important security concept for a number of browser-side programming languages, such as JavaScript. The policy permits scripts running on pages originating from the same site to access each other's methods and properties with no specific restrictions, but prevents access to most methods and properties across pages on different sites.

For you to be able to get data, it has to be:

Same protocol and host

You need to implement JSONP to workaround it.

I had the similar problem with eclipse kepler.I have followed these steps to resolve it

• Go to Help in Eclipse and Oper Eclipse Market Place option.
• Search for jdk 1.8 for kepler
• Install the required plugin.
• Restart the eclipse.

for reference, refer this link http://techno-terminal.blogspot.in/2016/05/jdk-18-compiler-compliance-is-not.html

The syntax '%' in %matplotlib inline is recognized by iPython (where it is set up to handle the magic methods), but not Python itself, which gives a SyntaxError. Here is given one solution.

Add the sheet name infront of the cell, e.g.:

=COUNTIFS(stock!A:A,"M",stock!C:C,"Yes")

Assumes the sheet name is "stock"

try:

 ALTER TABLE `user` CHANGE `id` `id` INT( 11 ) COMMENT 'id of user'  

Important difference between setting Classpath in Windows and Linux is path separator which is ";" (semi-colon) in Windows and ":" (colon) in Linux. Also %PATH% is used to represent value of existing path variable in Windows while ${PATH} is used for same purpose in Linux (in the bash shell). Here is the way to setup classpath in Linux:

export CLASSPATH=${CLASSPATH}:/new/path

but as such Classpath is very tricky and you may wonder why your program is not working even after setting correct Classpath. Things to note:

1. -cp options overrides CLASSPATH environment variable.
2. Classpath defined in Manifest file overrides both -cp and CLASSPATH envorinment variable.

Reference: How Classpath works in Java.

If you are creating a container from an image and like to expose multiple ports (not publish) you can use the following command:

docker create --name `container name` --expose 7000 --expose 7001 `image name`

Now, when you start this container using the docker start command, the configured ports above will be exposed.

You can use the following code for your requirement

map.forEach((k,v)->System.out.println("Item : " + k + " Count : " + v));

** Update ** A scalars converter has been added to retrofit that allows for a String response with less ceremony than my original answer below.

Example interface --

public interface GitHubService {
    @GET("/users/{user}")
    Call<String> listRepos(@Path("user") String user);
}

Add the ScalarsConverterFactory to your retrofit builder. Note: If using ScalarsConverterFactory and another factory, add the scalars factory first.

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(ScalarsConverterFactory.create())
    // add other factories here, if needed.
    .build();

You will also need to include the scalars converter in your gradle file --

implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'

--- Original Answer (still works, just more code) ---

I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject land. I suspect your specific problem might be better solved using a custom gson TypeAdapter or a retrofit Converter if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -

First, if you are using Retrofit 2, you should start using the Call API. Instead of sending an object to convert as the type parameter, use ResponseBody from okhttp --

public interface GitHubService {
    @GET("/users/{user}")
    Call<ResponseBody> listRepos(@Path("user") String user);
}

then you can create and execute your call --

GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Response<ResponseBody> response) {
        try {
            System.out.println(response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Throwable t) {
        e.printStackTrace();
    }
});

Note The code above calls string() on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream() instead. See the ResponseBody docs.

UPDATE

The bookmarklet hack below is broken due to XHR issues and API changes.

Thankfully Github now has "A Whole New Code Search" which does the job superbly.

Checkout this voodoo: Github code search userscript.

Follow the directions there, or if you hate bloating your browser with scripts and extensions, use my bookmarkified bundle of the userscript:

javascript:(function(){var s='https://raw.githubusercontent.com/skratchdot/github-enhancement-suite/master/build/github-enhancement-suite.user.js',t='text/javascript',d=document,n=navigator,e;(e=d.createElement('script')).src=s;e.type=t;d.getElementsByTagName('head')[0].appendChild(e)})();doIt('');void('');

Save the source above as the URL of a new bookmark. Browse to any Github repo, click the bookmark, and bam: in-page, ajaxified code search.

CAVEAT Github must index a repo before you can search it.

Abracadabra...

Here's a sample search from the annotated ECMAScript 5.1 specification repository:

If you don't want to download anything, you can use sqlite3 tool which is provided with adb :

Examining sqlite3 databases from a remote shell

and :

Command Line Shell For SQLite

Not exactly. You can't get two Streams out of one; this doesn't make sense -- how would you iterate over one without needing to generate the other at the same time? A stream can only be operated over once.

However, if you want to dump them into a list or something, you could do

stream.forEach((x) -> ((x == 0) ? heads : tails).add(x));

This code written above worked for me as well. Although, you can use the code I am writing here:

@echo off

@echo>"d:\testing\dblank.txt

If you want to write some text to dblank.txt then add the following line in the end of your code

@echo Writing text to dblank.txt> dblank.txt

I had success using .on() like so:

$('.leadtoscore').on('click', {event_type: 'shot'}, add_event);

Then inside the add_event function you get access to 'shot' like this:

event.data.event_type

See the .on() documentation for more info, where they provide the following example:

function myHandler( event ) {
  alert( event.data.foo );
}
$( "p" ).on( "click", { foo: "bar" }, myHandler );

const int is identical to int const, as is true with all scalar types in C. In general, declaring a scalar function parameter as const is not needed, since C's call-by-value semantics mean that any changes to the variable are local to its enclosing function.

$@ is the name of the target being generated, and $< the first prerequisite (usually a source file). You can find a list of all these special variables in the GNU Make manual.

For example, consider the following declaration:

all: library.cpp main.cpp

In this case:

• $@ evaluates to all
• $< evaluates to library.cpp
• $^ evaluates to library.cpp main.cpp

This link just gave me the best answer:

$ wget --no-clobber --convert-links --random-wait -r -p --level 1 -E -e robots=off -U mozilla http://base.site/dir/

Worked like a charm.

This is considered as features in Gitlab.

Maintainer / Owner access is never able to force push again for default & protected branch, as stated in this docs

The rubocop gem contributors propose in their Ruby Style Guide:

Prefer alias when aliasing methods in lexical class scope as the resolution of self in this context is also lexical, and it communicates clearly to the user that the indirection of your alias will not be altered at runtime or by any subclass unless made explicit.

class Westerner
  def first_name
   @names.first
  end

 alias given_name first_name
end

Always use alias_method when aliasing methods of modules, classes, or singleton classes at runtime, as the lexical scope of alias leads to unpredictability in these cases

module Mononymous
  def self.included(other)
    other.class_eval { alias_method :full_name, :given_name }
  end
end

class Sting < Westerner
  include Mononymous
end

The most flexible way is to use a custom Git command. For example, create the following Python script somewhere in your $PATH under the name git-rmbranch and make it executable:

#!/usr/bin/env python3

import argparse
import subprocess
import sys

def rmbranch(branch_name, remote, force):
    try:
        print(subprocess.run(['git', 'branch', '-D' if force else '-d', branch_name],
                             capture_output=True, check=True, encoding='utf-8').stdout, end='')
    except subprocess.CalledProcessError as exc:
        print(exc.stderr.replace(f'git branch -D {branch_name}', f'git rmbranch -f {branch_name}'), end='')
        return exc.returncode

    return subprocess.run(['git', 'push', remote, '--delete', branch_name]).returncode    

if __name__ == '__main__':
    parser = argparse.ArgumentParser(description='Delete a Git branch locally and remotely.')
    parser.add_argument('-r', '--remote', default='origin', help="The remote name (defaults to 'origin')")
    parser.add_argument('-f', '--force', action='store_true', help='Force deletion of not fully merged branches')
    parser.add_argument('branch_name', help='The branch name')
    args = parser.parse_args()

    sys.exit(rmbranch(args.branch_name, args.remote, args.force))

Then git rmbranch -h will show you usage information:

usage: git-rmbranch [-h] [-r REMOTE] [-f] branch_name

Delete a Git branch locally and remotely.

positional arguments:
  branch_name           The branch name

optional arguments:
  -h, --help            show this help message and exit
  -r REMOTE, --remote REMOTE
                        The remote name (defaults to 'origin')
  -f, --force           Force deletion of not fully merged branches

Note that git push origin --delete <branch_name> also removes the local remote-tracking branch (origin/<branch_name> by default), so no need to care about that.

P.S. You can find the latest version of this Git command here. Comments and suggestions are welcome.

Just download and re-install the node from this and this will fix all the path issues.

Don't forget to restart your command prompt or terminal.

jww is right — you're referencing the wrong intermediate certificate.

As you have been issued with a SHA256 certificate, you will need the SHA256 intermediate. You can grab it from here: http://secure2.alphassl.com/cacert/gsalphasha2g2r1.crt

I found this question after coming across something similar in my work, yesterday. My solution in the end was a hybrid of some of the approaches above:

function is_JSON($string) {

  return (is_null(json_decode($string, TRUE))) ? FALSE : TRUE;

}

Edit: As of February, 2020, there's now a first-class UI for automatically mounting Drive.

First, open the file browser on the left hand side. It will show a 'Mount Drive' button. Once clicked, you'll see a permissions prompt to mount Drive, and afterwards your Drive files will be present with no setup when you return to the notebook. The completed flow looks like so:

The original answer follows, below. (This will also still work for shared notebooks.)

You can mount your Google Drive files by running the following code snippet:

from google.colab import drive
drive.mount('/content/drive')

Then, you can interact with your Drive files in the file browser side panel or using command-line utilities.

Here's an example notebook

http://php.net/manual/en/reserved.variables.post.php

The first comment answers this.

<form ....>
<input name="person[0][first_name]" value="john" />
<input name="person[0][last_name]" value="smith" />
...
<input name="person[1][first_name]" value="jane" />
<input name="person[1][last_name]" value="jones" />
</form>

<?php
var_dump($_POST['person']);

array (
0 => array('first_name'=>'john','last_name'=>'smith'),
1 => array('first_name'=>'jane','last_name'=>'jones'),
)
?>

The name tag can work as an array.

It lets you define a @Section of code in your template that you can then include in other files. For example, a sidebar defined in the template, could be referenced in another included view.

//This could be used to render a @Section defined as @Section SideBar { ...
@RenderSection("SideBar", required: false);

Hope this helps.

I know your class is over, but in professional coding, let this be a lesson:

• "Deprecated" means "avoid use; it's going to be removed in the future"
• Deprecated things still work - just don't expect support or future-proofing
• If the requirement requires it, and you can't negotiate it away, just use the deprecated construct.
  
  • If you're really concerned, develop the alternative implementation on the side and keep it ready for the inevitable failure
  • Charge for the extra work now. By requesting a deprecated feature, they are asking you to double the work. You're going to see it again anyway, so might as well front-load it.
  • When the failure happens, let the interested party know that this was what you feared; that you prepared for it, but it'll take some time
  • Deploy your solution as quickly as you can (there will be bugs)
  • Gain rep for preventing excessive downtime.

As you've noticed, the WHERE clause doesn't allow you to use aggregates in it. That's what the HAVING clause is for.

HAVING t1.field3=MAX(t1.field3)

In addition to Mathias answer.

Although not mentioned in OP, if you also need to see the Powershell specific/related internal variables, you need to use Get-Variable:

$ Get-Variable

These also include stuff you may have set in your profile startup script.

Something fairly ODBC compliant if needed might be the following:

select ifnull(repeat('0', 5 - (floor(log10(FIELD_NAME)) + 1)), '')
        + cast (FIELD as varchar(10))
  from TABLE_NAME

This bases on the fact that the amount of digits for a base-10 number can be found by the integral component of its log. From this we can subtract it from the desired padding width. Repeat will return null for values under 1 so we need ifnull.

Navigate to /tomcat-root/conf folder. Within you will find the server.xml file.

Open the server.xml in your preferred editor. Search the below similar statement (not exactly same as below will differ)

    <Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Going to give the port number to 9090

     <Connector port="9090" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Save the file and restart the server. Now the tomcat will listen at port 9090

Node is used to represent tags in general. Divided to 3 types:

Attribute Note: is node which inside its has attributes. Exp: <p id=”123”></p>

Text Node: is node which between the opening and closing its have contian text content. Exp: <p>Hello</p>

Element Node : is node which inside its has other tags. Exp: <p><b></b></p>

Each node may be types simultaneously, not necessarily only of a single type.

Element is simply a element node.

If the "Customer don't want to install and buy MS Office on a server not at any price", then you cannot use Excel ... But I cannot get the trick: it's all about one basic Office licence which costs something like 150 USD ... And I guess that spending time finding an alternative will cost by far more than this amount!

There is a benefit of private methods absence. You can move the logic that you intended to hide to the separate class and use it as delegate. In this case you can mark delegate object as private and it will not be visible from outside. Moving logic to the separate class (maybe several) makes better design of your project. Cause your classes become simpler and your methods are grouped in classes with proper names.

From http://yassershaikh.com/what-is-the-difference-between-strings-and-stringbuilder-in-c-net/

Short Answer : String is immutable – whereas StringBuilder is mutable.

What does that mean ? Wiki says : In object-oriented, an immutable object is an object whose state cannot be modified after it is created. This is in contrast to a mutable object, which can be modified after it is created.

From the StringBuilder Class documentation:

The String object is immutable. Every time you use one of the methods in the System.String class, you create a new string object in memory, which requires a new allocation of space for that new object.

In situations where you need to perform repeated modifications to a string, the overhead associated with creating a new String object can be costly.

The System.Text.StringBuilder class can be used when you want to modify a string without creating a new object. For example, using the StringBuilder class can boost performance when concatenating many strings together in a loop.

You can use StringTemplate library, it offers what you want and much more.

import org.antlr.stringtemplate.*;

final StringTemplate hello = new StringTemplate("Hello, $name$");
hello.setAttribute("name", "World");
System.out.println(hello.toString());

Converting Using OpenSSL

These commands allow you to convert certificates and keys to different formats to make them compatible with specific types of servers or software.

• Convert a DER file (.crt .cer .der) to PEM

  openssl x509 -inform der -in certificate.cer -out certificate.pem
  

• Convert a PEM file to DER

  openssl x509 -outform der -in certificate.pem -out certificate.der
  

• Convert a PKCS#12 file (.pfx .p12) containing a private key and certificates to PEM

  openssl pkcs12 -in keyStore.pfx -out keyStore.pem -nodes
  
  You can add -nocerts to only output the private key or add -nokeys to only output the certificates.

Generate rsa keys by OpenSSL

• Using OpenSSL on the command line you’d first need to generate a public and private key, you should password protect this file using the -passout argument, there are many different forms that this argument can take so consult the OpenSSL documentation about that.

  openssl genrsa -out private.pem 1024
  

• This creates a key file called private.pem that uses 1024 bits. This file actually have both the private and public keys, so you should extract the public one from this file:

  openssl rsa -in private.pem -out public.pem -outform PEM -pubout
  
  or
  
  openssl rsa -in private.pem -pubout > public.pem
  
  or
  
  openssl rsa -in private.pem -pubout -out public.pem
  

  You’ll now have public.pem containing just your public key, you can freely share this with 3rd parties. You can test it all by just encrypting something yourself using your public key and then decrypting using your private key, first we need a bit of data to encrypt:

• Example file :

  echo 'too many secrets' > file.txt
  

• You now have some data in file.txt, lets encrypt it using OpenSSL and the public key:

  openssl rsautl -encrypt -inkey public.pem -pubin -in file.txt -out file.ssl
  

• This creates an encrypted version of file.txt calling it file.ssl, if you look at this file it’s just binary junk, nothing very useful to anyone. Now you can unencrypt it using the private key:

  openssl rsautl -decrypt -inkey private.pem -in file.ssl -out decrypted.txt
  

• You will now have an unencrypted file in decrypted.txt:

  cat decrypted.txt
  |output -> too many secrets
  

RSA TOOLS Options in OpenSSL

• NAME

  rsa - RSA key processing tool

• SYNOPSIS

  openssl rsa [-help] [-inform PEM|NET|DER] [-outform PEM|NET|DER] [-in filename] [-passin arg] [-out filename] [-passout arg] [-aes128] [-aes192] [-aes256] [-camellia128] [-camellia192] [-camellia256] [-des] [-des3] [-idea] [-text] [-noout] [-modulus] [-check] [-pubin] [-pubout] [-RSAPublicKey_in] [-RSAPublicKey_out] [-engine id]

• DESCRIPTION

  The rsa command processes RSA keys. They can be converted between various forms and their components printed out. Note this command uses the traditional SSLeay compatible format for private key encryption: newer applications should use the more secure PKCS#8 format using the pkcs8 utility.

• COMMAND OPTIONS

  -help
  

  Print out a usage message.

  -inform DER|NET|PEM
  

  This specifies the input format. The DER option uses an ASN1 DER encoded form compatible with the PKCS#1 RSAPrivateKey or SubjectPublicKeyInfo format. The PEM form is the default format: it consists of the DER format base64 encoded with additional header and footer lines. On input PKCS#8 format private keys are also accepted. The NET form is a format is described in the NOTES section.

  -outform DER|NET|PEM
  

  This specifies the output format, the options have the same meaning as the -inform option.

  -in filename
  

  This specifies the input filename to read a key from or standard input if this option is not specified. If the key is encrypted a pass phrase will be prompted for.

  -passin arg
  

  the input file password source. For more information about the format of arg see the PASS PHRASE ARGUMENTS section in openssl.

  -out filename
  

  This specifies the output filename to write a key to or standard output if this option is not specified. If any encryption options are set then a pass phrase will be prompted for. The output filename should not be the same as the input filename.

  -passout password
  

  the output file password source. For more information about the format of arg see the PASS PHRASE ARGUMENTS section in openssl.

  -aes128|-aes192|-aes256|-camellia128|-camellia192|-camellia256|-des|-des3|-idea
  

  These options encrypt the private key with the specified cipher before outputting it. A pass phrase is prompted for. If none of these options is specified the key is written in plain text. This means that using the rsa utility to read in an encrypted key with no encryption option can be used to remove the pass phrase from a key, or by setting the encryption options it can be use to add or change the pass phrase. These options can only be used with PEM format output files.

  -text
  

  prints out the various public or private key components in plain text in addition to the encoded version.

  -noout
  

  this option prevents output of the encoded version of the key.

  -modulus
  

  this option prints out the value of the modulus of the key.

  -check
  

  this option checks the consistency of an RSA private key.

  -pubin
  

  by default a private key is read from the input file: with this option a public key is read instead.

  -pubout
  

  by default a private key is output: with this option a public key will be output instead. This option is automatically set if the input is a public key.

  -RSAPublicKey_in, -RSAPublicKey_out
  

  like -pubin and -pubout except RSAPublicKey format is used instead.

  -engine id
  

  specifying an engine (by its unique id string) will cause rsa to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms.

• NOTES

  The PEM private key format uses the header and footer lines:

  -----BEGIN RSA PRIVATE KEY-----
  
  -----END RSA PRIVATE KEY-----
  

  The PEM public key format uses the header and footer lines:

  -----BEGIN PUBLIC KEY-----
  
  -----END PUBLIC KEY-----
  

  The PEM RSAPublicKey format uses the header and footer lines:

  -----BEGIN RSA PUBLIC KEY-----
  
  -----END RSA PUBLIC KEY-----
  

  The NET form is a format compatible with older Netscape servers and Microsoft IIS .key files, this uses unsalted RC4 for its encryption. It is not very secure and so should only be used when necessary.

  Some newer version of IIS have additional data in the exported .key files. To use these with the utility, view the file with a binary editor and look for the string "private-key", then trace back to the byte sequence 0x30, 0x82 (this is an ASN1 SEQUENCE). Copy all the data from this point onwards to another file and use that as the input to the rsa utility with the -inform NET option.

  EXAMPLES

  To remove the pass phrase on an RSA private key:

   openssl rsa -in key.pem -out keyout.pem
  

  To encrypt a private key using triple DES:

   openssl rsa -in key.pem -des3 -out keyout.pem
  

  To convert a private key from PEM to DER format:

    openssl rsa -in key.pem -outform DER -out keyout.der
  

  To print out the components of a private key to standard output:

    openssl rsa -in key.pem -text -noout
  

  To just output the public part of a private key:

    openssl rsa -in key.pem -pubout -out pubkey.pem
  

  Output the public part of a private key in RSAPublicKey format:

    openssl rsa -in key.pem -RSAPublicKey_out -out pubkey.pem
  

In my case the error was not caused by any of the above xml namespace issues. Instead it was the location of the android:id attribute - it needed to be the first item in the particular element's declaration.

So this:

<TextView android:layout_width="fill_parent" 
      android:layout_height="wrap_content"
      android:id="@+id/bottomtext" 
      android:singleLine="true" />

... needed to read like this:

<TextView android:id="@+id/bottomtext" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content"
      android:singleLine="true" />

I found the answer!

I want to acknowledge the hard work of everyone in trying to find a better way to solve this problem, unfortunately because of a series of larger constraints I am unable to select them as the "answer" (I am voting them up because you deserve points for contributing).

The specific problem I was facing was a JavaScript onScoll event that was firing but a subsequent CSS update that wasn't causing IE8 (in standards mode) to redraw. Even stranger was the fact that in some pages it was redrawing while in others (with no obvious similarity) it wasn't. The solution in the end was to add the following CSS

#ActionBox {
  position: relative;
  float: right;
}

Here is an updated pastbin showing this (I added some more style to show how I am implementing this code). The IE "edit code" then "view output" bug fudgey talked about still occurs (but it seems to be a event binding issue unique to pastbin (and similar services)

I don't know why adding "float: right" allows IE8 to complete a redraw on an event that was already firing, but for some reason it does.

---- Remove Constraint ----
EXEC sp_MSForEachTable "ALTER TABLE ? NOCHECK CONSTRAINT all"

---- Delete Data ----
EXEC sp_MSForEachTable "DELETE FROM ?"

---- Add Constraint ----
EXEC sp_MSForEachTable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all"

---- Reset Identity value ----
EXEC sp_MSForEachTable "DBCC CHECKIDENT ( '?', RESEED, 0)"

+ theme(plot.title = element_text(size=22))

Here is the full set of things you can change in element_text:

element_text(family = NULL, face = NULL, colour = NULL, size = NULL,
  hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
  color = NULL)

Select URColumnName From URTableName Where length(URColumnName ) IN 
(Select max(length(URColumnName)) From URTableName);

This will give you the records in that particular column which has the maximum length.

for simple comments:

set serveroutput on format wrapped;
begin
    DBMS_OUTPUT.put_line('simple comment');
end;
/

-- do something

begin
    DBMS_OUTPUT.put_line('second simple comment');
end;
/

you should get:

anonymous block completed
simple comment

anonymous block completed
second simple comment

if you want to print out the results of variables, here's another example:

set serveroutput on format wrapped;
declare
a_comment VARCHAR2(200) :='first comment';
begin
    DBMS_OUTPUT.put_line(a_comment);
end;

/

-- do something


declare
a_comment VARCHAR2(200) :='comment';
begin
    DBMS_OUTPUT.put_line(a_comment || 2);
end;

your output should be:

anonymous block completed
first comment

anonymous block completed
comment2

Alternatively, you can cast the row DataItem to a class and then add condition based on the class properties. Here is a sample that I used to convert the row to a class/model named TimetableModel, then in if statement you have access to all class fields/properties:

protected void GridView_TimeTable_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    var tt = (TimetableModel)(e.Row.DataItem);
                     if (tt.Unpublsihed )
                       e.Row.BackColor = System.Drawing.Color.Red;
                     else
                       e.Row.BackColor = System.Drawing.Color.Green;
                }
            }
        }

It is impossible to terminate a thread unless the code running in that thread checks for and allows termination.

You said: "Sadly I must kill/restart it ... I don't have complete control over the contents of the thread and for my situation it requires a restart"

If the contents of the thread does not allow for termination of its exectuion then you can not terminate that thread.

In your post you said: "My first attempt was with ExecutorService but I can't seem to find a way for it restart a task. When I use .shutdownnow()..."

If you look at the source of "shutdownnow" it just runs through and interrupts the currently running threads. This will not stop their execution unless the code in those threads checks to see if it has been ineterrupted and, if so, stops execution itself. So shutdownnow is probably not doing what you think.

Let me illustrate what I mean when I say that the contents of the thread must allow for that thread to be terminated:

myExecutor.execute(new Runnable() {
 public void run() {
  while (true) {
    System.out.println("running");
  }
 }
 });
myExecutor.shutdownnow();

That thread will continue to run forever, even though shutdownnow was called, because it never checks to see if it has been terminated or not. This thread, however, will shut down:

myExecutor.execute(new Runnable() {
 public void run() {
  while (!Thread.interrupted()) {
    System.out.println("running");
  }
 }
 });
myExecutor.shutdownnow();

Since this thread checks to see whether or not it has been interrupted / shut down / terminated.

So if you want a thread that you can shut down, you need to make sure it checks to see if it has been interrupted. If you want a thread that you can "shut down" and "restart" you can make a runnable that can take new tasks as was mentioned before.

Why can you not shut down a running thread? Well I actually lied, you can call "yourThread.stop()" but why is this a bad idea? The thread could be in a synchronized (or other critical section, but we will limit ourselves to setions guarded by the syncrhonized key word here) section of code when you stop it. synch blocks are supposed to be executed in their entirity and only by one thread before being accessed by some other thread. If you stop a thread in the middle of a synch block, the protection put into place by the synch block is invalidated and your program will get into an unknown state. Developers make put stuff in synch blocks to keep things in synch, if you use threadInstance.stop() you destroy the meaning of synchronize, what the developer of that code was trying to accomplish and how the developer of that code expected his synchronized blocks to behave.

There are several ways rsync compares files -- the authoritative source is the rsync algorithm description: https://www.andrew.cmu.edu/course/15-749/READINGS/required/cas/tridgell96.pdf. The wikipedia article on rsync is also very good.

For local files, rsync compares metadata and if it looks like it doesn't need to copy the file because size and timestamp match between source and destination it doesn't look further. If they don't match, it cp's the file. However, what if the metadata do match but files aren't actually the same? Then rsync probably didn't do what you intended.

Files that are the same size may still have changed. One simple example is a text file where you correct a typo -- like changing "teh" to "the". The file size is the same, but the corrected file will have a newer timestamp. --size-only says "don't look at the time; if size matches assume files match", which would be the wrong choice in this case.

On the other hand, suppose you accidentally did a big cp -r A B yesterday, but you forgot to preserve the time stamps, and now you want to do the operation in reverse rsync B A. All those files you cp'ed have yesterday's time stamp, even though they weren't really modified yesterday, and rsync will by default end up copying all those files, and updating the timestamp to yesterday too. --size-only may be your friend in this case (modulo the example above).

--ignore-times says to compare the files regardless of whether the files have the same modify time. Consider the typo example above, but then not only did you correct the typo but you used touch to make the corrected file have the same modify time as the original file -- let's just say you're sneaky that way. Well --ignore-times will do a diff of the files even though the size and time match.
