I had success after using ade.exe as explained above, plus using the latest version of Chrome Canary. Apparently your desktop version of Chrome has to be higher than the version running on your Android device.

The Heroku CLI has an easy shortcut for this. For an app named 'falling-wind-1624':

$ heroku git:remote -a falling-wind-1624

You may or may not have to use setOpaque method to ensure that the colors show up by passing true to the method.

You have to run a web server (e.g. Apache) and browse to your localhost, mostly likely on port 80.

What you really ought to do is install an all-in-one package like XAMPP, it bundles Apache, MySQL PHP, and Perl (if you were so inclined) as well as a few other tools that work with Apache and MySQL - plus it's cross platform (that's what the 'X' in 'XAMPP' stands for).

Once you install XAMPP (and there is an installer, so it shouldn't be hard) open up the control panel for XAMPP and then click the "Start" button next to Apache - note that on applications that require a database, you'll also need to start MySQL (and you'll be able to interface with it through phpMyAdmin). Once you've started Apache, you can browse to http://localhost.

Again, regardless of whether or not you choose XAMPP (which I would recommend), you should just have to start Apache.

Non-Americans take note! If you use Excel with "." as 1000 separator, you need to replace the "," with a "." in the formula, such as:

[>=1000]€ #.##0." K";[<=-1000]-€ #.##0." K";0

The code above will display € 62.123 as "€ 62 K".

Have the same problem with white screen during transition from one fragment to another. Have navigation and animations set in action in navigation.xml.

Background in all fragments the same but white blank screen. So i set navOptions in fragment during executing transition

          //Transition options
        val options = navOptions {
            anim {
                enter = R.anim.slide_in_right
                exit = R.anim.slide_out_left
                popEnter = R.anim.slide_in_left
                popExit = R.anim.slide_out_right
            }
        }

.......................

  this.findNavController().navigate(SampleFragmentDirections.actionSampleFragmentToChartFragment(it),
                    options)

It worked for me. No white screen between transistion. Magic )

Mine was something simple/stupid. Newbie mistake, for anyone that has converted their NSManagedObject to a normal NSObject.

I had:

@dynamic order_id;

when i should have had:

@synthesize order_id;

You may try this too.

public static String[][] getArrayFromHash(Hashtable<String,String> data){
        String[][] str = null;
        {
            Object[] keys = data.keySet().toArray();
            Object[] values = data.values().toArray();
            str = new String[keys.length][values.length];
            for(int i=0;i<keys.length;i++) {
                str[0][i] = (String)keys[i];
                str[1][i] = (String)values[i];
            }
        }
        return str;
    }

Here I am using String as return type. You may change it to required return type by you.

Here's what I use:

<logger name="org.hibernate">
    <level value="warn"/>
</logger>

<logger name="org.hibernate.SQL">
    <level value="warn"/>
</logger>

<logger name="org.hibernate.type">
    <level value="warn"/>
</logger>

<root>
    <priority value="info"/>
    <appender-ref ref="C1"/>
</root> 

Obviously, I don't like to see Hibernate messages ;) -- set the level to "debug" to get the output.

One of the values you pass on to Ancestors becomes None at some point, it says, so check if otu, tree, tree[otu] or tree[otu][0] are None in the beginning of the function instead of only checking tree[otu][0][0] == None. But perhaps you should reconsider your path of action and the datatype in question to see if you could improve the structure somewhat.

This option comes in curl 7.73.0:

curl --create-dirs -O --output-dir /tmp/receipes https://example.com/pancakes.jpg

In Go 1.13 and later, you can use Value.IsZero method offered in reflect package.

if reflect.ValueOf(v).IsZero() {
    // v is zero, do something
}

Apart from basic types, it also works for Array, Chan, Func, Interface, Map, Ptr, Slice, UnsafePointer, and Struct. See this for reference.

Swift 4.2

var urlString = originalString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)

Swift 3.0

var address = "American Tourister, Abids Road, Bogulkunta, Hyderabad, Andhra Pradesh, India"
let escapedAddress = address.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)
let urlpath = String(format: "http://maps.googleapis.com/maps/api/geocode/json?address=\(escapedAddress)")

Use stringByAddingPercentEncodingWithAllowedCharacters:

var escapedAddress = address.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())

Use stringByAddingPercentEscapesUsingEncoding: Deprecated in iOS 9 and OS X v10.11

var address = "American Tourister, Abids Road, Bogulkunta, Hyderabad, Andhra Pradesh, India"
var escapedAddress = address.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)
let urlpath = NSString(format: "http://maps.googleapis.com/maps/api/geocode/json?address=\(escapedAddress)")

My scenario is when the user strikes the enter key while typing in textarea i have to include a line break.I achieved this using the below code......Hope it may helps somebody......

function CheckLength()
{
    var keyCode = event.keyCode
    if (keyCode == 13)
    {
        document.getElementById('ctl00_ContentPlaceHolder1_id_txt_Suggestions').value = document.getElementById('ctl00_ContentPlaceHolder1_id_txt_Suggestions').value + "\n<br>";
    }
}

My mistake was forgetting to add the .ThenInclude(s => s.SubChildEntities) onto the parent .Include(c => c.SubChildEntities) to the Controller action when attempting to call the SubChildEntities in the Razor view.

var <parent> = await _context.Parent
            .Include(c => c.<ChildEntities>)
            .ThenInclude(s => s.<SubChildEntities>)
            .SingleOrDefaultAsync(m => m.Id == id);

It should be noted that Visual Studio 2017 Community's IntelliSense doesn't pick up the SubChildEntities object in the lambda expression in the .ThenInclude(). It does successfully compile and execute though.

If you use SQLiteOpenHelper you can do this

        String myPath = DB_PATH + DB_NAME;
        SQLiteDatabase.deleteDatabase(new File(myPath));

A problem with not putting 'return' explicitly at the end is that if one adds additional statements at the end of the method, suddenly the return value is wrong:

foo <- function() {
    dosomething()
}

This returns the value of dosomething().

Now we come along the next day and add a new line:

foo <- function() {
    dosomething()
    dosomething2()
}

We wanted our code to return the value of dosomething(), but instead it no longer does.

With an explicit return, this becomes really obvious:

foo <- function() {
    return( dosomething() )
    dosomething2()
}

We can see that there is something strange about this code, and fix it:

foo <- function() {
    dosomething2()
    return( dosomething() )
}

From the Mozilla Developer Network:

There is no way to stop or break a forEach() loop other than by throwing an exception. If you need such behavior, the forEach() method is the wrong tool.

Early termination may be accomplished with:

• A simple loop
• A for...of loop
• Array.prototype.every()
• Array.prototype.some()
• Array.prototype.find()
• Array.prototype.findIndex()

The other Array methods: every(), some(), find(), and findIndex() test the array elements with a predicate returning a truthy value to determine if further iteration is required.

Since anonymous classes extend the given class you can store them in a variable.

eg.

Thread t = new Thread()
{
    public void run() {
        System.out.println("blah");
    }
};
t.start();

Alternatively, you can just call the start method on the object you have immediately created.

new Thread()
{
    public void run() {
        System.out.println("blah");
    }
}.start();
// similar to new Thread().start();

Though personally, I would always advise creating an anonymous instance of Runnable rather than Thread as the compiler will warn you if you accidentally get the method signature wrong (for an anonymous class it will warn you anyway I think, as anonymous classes can't define new non-private methods).

eg

new Thread(new Runnable()
{
    @Override
    public void run() {
        System.out.println("blah");
    }
}).start();

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

Check my code that will work for integer and String.

Assume our first number is 129018. And we want to add zeros to that so the the length of final string will be 10. For that you can use following code

    int number=129018;
    int requiredLengthAfterPadding=10;
    String resultString=Integer.toString(number);
    int inputStringLengh=resultString.length();
    int diff=requiredLengthAfterPadding-inputStringLengh;
    if(inputStringLengh<requiredLengthAfterPadding)
    {
        resultString=new String(new char[diff]).replace("\0", "0")+number;
    }        
    System.out.println(resultString);

Use the % wildcard, which matches any number of characters.

SELECT * FROM Accounts WHERE Username LIKE '%query%'

You are trying to do too much in the main method. You need to break this up into more manageable parts. Write a method boolean isPrime(int n) that returns true if a number is prime, and false otherwise. Then modify the main method to use isPrime.

Update

As noted in another answer, now there is an option for private repos also for simple users

Annotate your util classes with @Ignore. This will cause JUnit not to try and run them as tests.

You can use the following css to resize the image for mobile view

object-fit: scale-down; max-width: 100%

Use the Timer class.

public static void Main()
{
    System.Timers.Timer aTimer = new System.Timers.Timer();
    aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
    aTimer.Interval = 5000;
    aTimer.Enabled = true;

    Console.WriteLine("Press \'q\' to quit the sample.");
    while(Console.Read() != 'q');
}

 // Specify what you want to happen when the Elapsed event is raised.
 private static void OnTimedEvent(object source, ElapsedEventArgs e)
 {
     Console.WriteLine("Hello World!");
 }

The Elapsed event will be raised every X amount of milliseconds, specified by the Interval property on the Timer object. It will call the Event Handler method you specify. In the example above, it is OnTimedEvent.

It seems that you are right. No option scales the image better:
http://www.maxrev.de/html/image-scaling.html

I've tested FF14, IE9, OP12 and GC21. Only GC has a better scaling that can be deactivated through image-rendering: -webkit-optimize-contrast. All other browsers have no/poor scaling.

Screenshot of the different output: http://www.maxrev.de/files/2012/08/screenshot_interpolation_jquery_animate.png

Update 2017

Meanwhile some more browsers support smooth scaling:

• ME38 (Microsoft Edge) has good scaling. It can't be disabled and it works for JPEG and PNG, but not for GIF.

• FF51 (Regarding @karthik 's comment since FF21) has good scaling that can be disabled through the following settings:

  image-rendering: optimizeQuality
  image-rendering: optimizeSpeed
  image-rendering: -moz-crisp-edges
  

  Note: Regarding MDN the optimizeQuality setting is a synonym for auto (but auto does not disable smooth scaling):

  The values optimizeQuality and optimizeSpeed present in early draft (and coming from its SVG counterpart) are defined as synonyms for the auto value.

• OP43 behaves like GC (not suprising as it is based on Chromium since 2013) and its still this option that disables smooth scaling:

  image-rendering: -webkit-optimize-contrast
  

No support in IE9-IE11. The -ms-interpolation-mode setting worked only in IE6-IE8, but was removed in IE9.

P.S. Smooth scaling is done by default. This means no image-rendering option is needed!

Making @sulai suggestion more generic :

@TargetApi(Build.VERSION_CODES.HONEYCOMB) // API 11
public static <T> void executeAsyncTask(AsyncTask<T, ?, ?> asyncTask, T... params) {
    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
        asyncTask.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, params);
    else
        asyncTask.execute(params);
}   

Some examples that work for me:

$ tree -L 1 -F .
.
+-- A.Show.2020.1400MB.txt
+-- Some Show S01E01 the Loreming.txt

0 directories, 2 files

## remove "1400MB" (I: ignore case) ...

$ for f in *; do mv 2>/dev/null -v "$f" "`echo $f | sed -r 's/.[0-9]{1,}mb//I'`"; done;
renamed 'A.Show.2020.1400MB.txt' -> 'A.Show.2020.txt'

## change "S01E01 the" to "S01E01 The"
## \U& : change (here: regex-selected) text to uppercase;
##       note also: no need here for `\1` in that regex expression

$ for f in *; do mv 2>/dev/null "$f" "`echo $f | sed -r "s/([0-9] [a-z])/\U&/"`"; done

$ tree -L 1 -F .

Case 1: Insert Row and Query Foreign Key

Here is an alternate syntax I use:

INSERT INTO tab_student 
   SET name_student = 'Bobby Tables',
       id_teacher_fk = (
       SELECT id_teacher
         FROM tab_teacher
        WHERE name_teacher = 'Dr. Smith')

I'm doing this in Excel to import a pivot table to a dimension table and a fact table in SQL so you can import to both department and expenses tables from the following:

Case 2: Insert Row and Then Insert Dependant Row

Luckily, MySQL supports LAST_INSERT_ID() exactly for this purpose.

INSERT INTO tab_teacher
   SET name_teacher = 'Dr. Smith';
INSERT INTO tab_student 
   SET name_student = 'Bobby Tables',
       id_teacher_fk = LAST_INSERT_ID()

Alternative to @HostListener and scroll output on the element I would suggest using fromEvent from RxJS since you can chain it with filter() and distinctUntilChanges() and can easily skip flood of potentially redundant events (and change detections).

Here is a simple example:

// {static: true} can be omitted if you don't need this element/listener in ngOnInit
@ViewChild('elementId', {static: true}) el: ElementRef;

// ...

fromEvent(this.el.nativeElement, 'scroll')
  .pipe(
    // Is elementId scrolled for more than 50 from top?
    map((e: Event) => (e.srcElement as Element).scrollTop > 50),
    // Dispatch change only if result from map above is different from previous result
    distinctUntilChanged());

If you are using

a = []; 

Then you are assigning new array reference to a, if reference in a is already assigned to any other variable, then it will not empty that array too and hence garbage collector will not collect that memory.

For ex.

var a=[1,2,3];
var b=a;
a=[];
console.log(b);// It will print [1,2,3];

or

a.length = 0;

When we specify a.length, we are just resetting boundaries of the array and memory for rest array elements will be connected by garbage collector.

Instead of these two solutions are better.

a.splice(0,a.length)

and

while(a.length > 0) {
    a.pop();
}

As per previous answer by kenshou.html, second method is faster.

If you lost a keystore file, don't create/update the new one with another set of value. First do the thorough search. Because it will overwrite the old one, so it will not match to your previous apk.

If you use eclipse most probably it will store in default path. For MAC (eclipse) it will be in your elispse installation path something like:

/Applications/eclipse/Eclipse.app/Contents/MacOS/

then your keystore file without any extension. You need root privilege to access this path (file).

This maybe what you're looking for:

awk 'BEGIN {FS=" ";} {printf "'\''%s'\'' ", $1}'

That is, with '\'' you close the opening ', then print a literal ' by escaping it and finally open the ' again.

mysql -u <user> -p -e "select * from schema.table"

Use an abstract class when you want to define a template for a group of sub-classes , and you have at least some implementation code that call sub-classes could use.

Use an interface when you want to define the role that other classes can play, regardless of where those classes are in the inheritance tree

you extend an abstract class

you implement an interface :)

in an interface all the fields are automatically public static final and all the methods are public whereas an abstract class allows you a bit of flexibility here.

Be aware that the function File.GetLastWriteTime does not always work as expected, the values are sometimes not instantaneously updated by the OS. You may get an old Timestamp, even if the file has been modified right before.

The behaviour may vary between OS versions. For example, this unit test worked well every time on my developer machine, but it always fails on our build server.

  [TestMethod]
  public void TestLastModifiedTimeStamps()
  {
     var tempFile = Path.GetTempFileName();
     var lastModified = File.GetLastWriteTime(tempFile);
     using (new FileStream(tempFile, FileMode.Create, FileAccess.Write, FileShare.None))
     {

     }
     Assert.AreNotEqual(lastModified, File.GetLastWriteTime(tempFile));
  }

See File.GetLastWriteTime seems to be returning 'out of date' value

Your options:

a) live with the occasional omissions.

b) Build up an active component realising the observer pattern (eg. a tcp server client structure), communicating the changes directly instead of writing / reading files. Fast and flexible, but another dependency and a possible point of failure (and some work, of course).

c) Ensure the signalling process by replacing the content of a dedicated signal file that other processes regularly read. It´s not that smart as it´s a polling procedure and has a greater overhead than calling File.GetLastWriteTime, but if not checking the content from too many places too often, it will do the work.

You can write a function that splits the database by a factor, orders by another desired variable, extract the number of rows you want in each factor (category) and combine these into a database.

top<-function(x, num, c1,c2){
sorted<-x[with(x,order(x[,c1],x[,c2],decreasing=T)),]
splits<-split(sorted,sorted[,c1])
df<-lapply(splits,head,num)
do.call(rbind.data.frame,df)}

x is the dataframe;

num is the number of number of rows you would like to see;

c1 is the column number of the variable you would like to split by;

c2 is the column number of the variable you would like to rank by or handle ties.

Using the mtcars data, the function extracts the 3 heaviest cars (mtcars$wt is the 6th column) in each cylinder class (mtcars$cyl is the 2nd column)

You can also easily get the lightest in a class by changing head in the lapply function to tail OR by removing the decreasing=T argument in the order function which will return it to its default, decreasing=F.

RTM

From the docs for the Python random module:

Functions for integers:

random.randrange(stop)
random.randrange(start, stop[, step])

    Return a randomly selected element from range(start, stop, step).
    This is equivalent to choice(range(start, stop, step)), but doesn’t
    actually build a range object.

That explains why it only gives you 0, doesn't it. range(0,1) is [0]. It is choosing from a list consisting of only that value.

Also from those docs:

random.random()    
    Return the next random floating point number in the range [0.0, 1.0).

But if your inclusion of the numpy tag is intentional, you can generate many random floats in that range with one call using a np.random function.

It's a part of Apache Commons Lang as of ver. 3.0.

You've got several options how to do this, either:

• urlencode() or rawurlencode() - functions designed to encode URLs for http protocol
• str_replace() - "heavy machinery" string replace
• strtr() - would have better performance than str_replace() when replacing multiple characters
• preg_replace() use regular expressions (perl compatible)

strtr()

Assuming that you want to replace "\t" and " " with "%20":

$replace_pairs = array(
  "\t" => '%20',
  " " => '%20',
);
return strtr( $text, $replace_pairs)

preg_replace()

You've got few options here, either replacing just space ~ ~, again replacing space and tab ~[ \t]~ or all kinds of spaces ~\s~:

return preg_replace( '~\s~', '%20', $text);

Or when you need to replace string like this "\t \t \t \t" with just one %20:

return preg_replace( '~\s+~', '%20', $text);

_{I assumed that you really want to use manual string replacement and handle more types of whitespaces such as non breakable space ( )}

I also encountered this problem. I found after changing the table storage engine from MyISAM to Innodb, problem solved .

For what its worth, installing a system app to the /system/app directory will be:

adb push appname.apk /system/app/

Just ensure you're in the right directory where the target .apk file to be installed is, or you could just copy the .apk file to the platform-tools directory of the Android SDK and adb would definitely find it.

Here is one way to do it. Involves doing a little PHP as well.

The PHP part:

$filenameArray = [];

$handle = opendir(dirname(realpath(__FILE__)).'/images/');
        while($file = readdir($handle)){
            if($file !== '.' && $file !== '..'){
                array_push($filenameArray, "images/$file");
            }
        }

echo json_encode($filenameArray);

The jQuery part:

$.ajax({
            url: "getImages.php",
            dataType: "json",
            success: function (data) {

                $.each(data, function(i,filename) {
                    $('#imageDiv').prepend('<img src="'+ filename +'"><br>');
                });
            }
        });

So basically you do a PHP file to return you the list of image filenames as JSON, grab that JSON using an ajax call, and prepend/append them to the html. You would probably want to filter the files u grab from the folder.

Had some help on the php part from 1

Yes,

Commons library provides a built-in FixedSizeList which does not support the add, remove and clear methods (but the set method is allowed because it does not modify the List's size). In other words, if you try to call one of these methods, your list still retain the same size.

To create your fixed size list, just call

List<YourType> fixed = FixedSizeList.decorate(Arrays.asList(new YourType[100]));

You can use unmodifiableList if you want an unmodifiable view of the specified list, or read-only access to internal lists.

List<YourType> unmodifiable = java.util.Collections.unmodifiableList(internalList);

If you need an array, separate the array columns with a comma:

SELECT * FROM (VALUES('WOMENS'),('MENS'),('CHILDRENS')) as X([Attribute])
,(VALUES(742),(318)) AS z([StoreID])

So the way I got around this was in the command where i would normally run npm install or npm ci, i added NODE_ENV=build, and then NODE_ENV=production after the command, so my entire command came out to:

RUN NODE_ENV=build && npm ci && NODE_ENV=production

So far I haven't had any bad reactions, and my development dependencies which are used for building the application all worked / loaded correctly.

I find this to be a better solution than adding an additional command like npm install --only=dev because it takes less time, and enables me to use the npm ci command, which is faster and specifically designed to be run inside CI tools / build scripts. (See npi-ci documentation for more information on it)

Try the following:

$("#myanchor")[0].click()

As simple as that.

Step 01: You need to add jenkins for environment variables, Then you can use jenkins commands

Step 02: Go to "C:\Program Files (x86)\Jenkins" with admin prompt

Step 03: Choose your option: jenkins.exe stop / jenkins.exe start / jenkins.exe restart

You have to add Imports System.Runtime.InteropServices to the top of your source file.

Alternatively, you can fully qualify attribute name:

<System.Runtime.InteropService.DllImport("user32.dll", _
    SetLastError:=True, CharSet:=CharSet.Auto)> _

I was able to install libc6 2.17 in Debian Wheezy by editing the recommendations in perror's answer:

IMPORTANT
You need to exit out of your display manager by pressing CTRL-ALT-F1. Then you can stop x (slim) with sudo /etc/init.d/slim stop

(replace slim with mdm or lightdm or whatever)

Add the following line to the file /etc/apt/sources.list:

deb http://ftp.debian.org/debian experimental main

Should be changed to:

deb http://ftp.debian.org/debian sid main

Then follow the rest of perror's post:

Update your package database:

apt-get update

Install the eglibc package:

apt-get -t sid install libc6-amd64 libc6-dev libc6-dbg

IMPORTANT
After done updating libc6, restart computer, and you should comment out or remove the sid source you just added (deb http://ftp.debian.org/debian sid main), or else you risk upgrading your whole distro to sid.

Hope this helps. It took me a while to figure out.

On Windows and Linux : Ctrl + Shift + F

On Mac : ? + ? + F

Easiest way for changing order of striped:

Add empty tr before your table tr tags.

Add the dots to all values:

[[UIColor colorWithRed:222./255. green:227./255. blue: 229./255. alpha:1] CGColor]) ;

Otherwise, you are dividing float by int.

I got the error by having multiple tables on the page and trying to initialize them all at once like this:

$('table').DataTable();

After a lot of trial and error, I initialized them separately and the error went away:

$("#table1-id").DataTable();
$("#table2-id").DataTable();

Quite frankly, I believe people use these Dependency Injection libraries/frameworks because they just know how to do things in runtime, as opposed to load time. All this crazy machinery can be substituted by setting your CLASSPATH environment variable (or other language equivalent, like PYTHONPATH, LD_LIBRARY_PATH) to point to your alternative implementations (all with the same name) of a particular class. So in the accepted answer you'd just leave your code like

var logger = new Logger() //sane, simple code

And the appropriate logger will be instantiated because the JVM (or whatever other runtime or .so loader you have) would fetch it from the class configured via the environment variable mentioned above.

No need to make everything an interface, no need to have the insanity of spawning broken objects to have stuff injected into them, no need to have insane constructors with every piece of internal machinery exposed to the world. Just use the native functionality of whatever language you're using instead of coming up with dialects that won't work in any other project.

P.S.: This is also true for testing/mocking. You can very well just set your environment to load the appropriate mock class, in load time, and skip the mocking framework madness.

NODE USERS (REACT,EXPRESS) FOLLOW THESE STEPS

1. npm install base-64 --save
2. import { encode } from "base-64";

3.  const response = await fetch(URL, {
     method: 'post',
     headers: new Headers({
       'Authorization': 'Basic ' + encode(username + ":" + password),
       'Content-Type': 'application/json'
     }),
     body: JSON.stringify({
       "PassengerMobile": "xxxxxxxxxxxx",
       "Password": "xxxxxxx"
     })
   });
   const posts = await response.json();
   

4. Don't forget to define this whole function as async

An example of how to use "continue" labels in Java is:

public class Label {
    public static void main(String[] args) {
        int temp = 0;
        out: // label
        for (int i = 0; i < 3; ++i) {
            System.out.println("I am here");
            for (int j = 0; j < 20; ++j) {
                if(temp==0) {
                    System.out.println("j: " + j);
                    if (j == 1) {
                        temp = j;
                        continue out; // goto label "out"
                    }
                }
            }
        }
        System.out.println("temp = " + temp);
    }
}

Results:

I am here // i=0
j: 0
j: 1
I am here // i=1
I am here // i=2
temp = 1

Short Answer:

Simple rule of thumb: Use POST to create, use PUT to update.

Long Answer:

POST:

• POST is used to send data to server.
• Useful when the resource's URL is unknown

PUT:

• PUT is used to transfer state to the server
• Useful when a resource's URL is known

Longer Answer:

To understand it we need to question why PUT was required, what were the problems PUT was trying to solve that POST couldn't.

From a REST architecture's point of view there is none that matters. We could have lived without PUT as well. But from a client developer's point of view it made his/her life a lot simpler.

Prior to PUT, clients couldn't directly know the URL that the server generated or if all it had generated any or whether the data to be sent to the server is already updated or not. PUT relieved the developer of all these headaches. PUT is idempotent, PUT handles race conditions, and PUT lets the client choose the URL.

A more concise version is:

def softmax(x):
    return np.exp(x) / np.exp(x).sum(axis=0)

>>> s = "123mango abcd mango kiwi peach"
>>> s.split("mango", 1)
['123', ' abcd mango kiwi peach']
>>> s.split("mango", 1)[1]
' abcd mango kiwi peach'

I use variations of this all the time to process files...

for files in *.log; do echo "Do stuff with: $files"; echo "Do more stuff with: $files"; done;

If processing lists of files is what you're interested in, look into the -execdir option for files.

I tried the above solution but I found it unsuitable for large amounts of data. I then discovered the stream feature:

MongoClient.connect("...", function(err, db){
    var c = db.collection('yourCollection');
    var s = c.find({/* your query */}).stream();
    s.on('data', function(doc){
        c.update({_id: doc._id}, {$set: {name : doc.firstName + ' ' + doc.lastName}}, function(err, result) { /* result == true? */} }
    });
    s.on('end', function(){
        // stream can end before all your updates do if you have a lot
    })
})

If you want to add 10 items to your ArrayList you may try that:

for (int i = 0; i < 10; i++)
    arr.add(i);

If you have already declare an array size variable you would use the variable size instead of number '10'

Here is an example :

=begin 
print "Give me a number:"
number = gets.chomp.to_f

total = number * 10
puts  "The total value is : #{total}"

=end

Everything you place in between =begin and =end will be treated as a comment regardless of how many lines of code it contains between.

Note: Make sure there is no space between = and begin:

• Correct: =begin
• Wrong: = begin

It is an anchor for links within a page - also known as "anchor tag"

I was trying to find a better answer that was more standalone, so I started to think about how JQuery does events and custom events. Since click (from JQuery) is just any event, I thought that all I had to do was trigger the event given that the iframe's content has been clicked on. Thus, this was my solution

$(document).ready(function () {
    $("iframe").each(function () {
        //Using closures to capture each one
        var iframe = $(this);
        iframe.on("load", function () { //Make sure it is fully loaded
            iframe.contents().click(function (event) {
                iframe.trigger("click");
            });
        });

        iframe.click(function () {
            //Handle what you need it to do
        });
    });
});

You need to add an additional parameter:

$http.get(url).then(
    function(response) {
        console.log('get',response)
    },
    function(data) {
        // Handle error here
    })

Using the provided IntentInegrator is better. It allows you to prompt your user to install the barcode scanner if they do not have it. It also allows you to customize the messages. The IntentIntegrator.REQUEST_CODE constant holds the value of the request code for the onActivityResult to check for in the above if block.

IntentIntegrator intentIntegrator = new IntentIntegrator(this); // where this is activity 
intentIntegrator.initiateScan(IntentIntegrator.ALL_CODE_TYPES); // or QR_CODE_TYPES if you need to scan QR

You are using pip3 to install flask-script which is associated with python 3.5. However, you are trying to upgrade pip associated with the python 2.7, try running pip3 install --upgrade pip.

It might be a good idea to take some time and read about virtual environments in Python. It isn't a best practice to install all of your packages to the base python installation. This would be a good start: http://docs.python-guide.org/en/latest/dev/virtualenvs/

I have come to point out the answer nobody seems to see here. You can fullfill all requests you have made with pure CSS and it's very simple. Just use Media Queries. Media queries can check the orientation of the user's screen, or viewport. Then you can style your images depending on the orientation.

Just set your default CSS on your images like so:

img {
   width:auto;
   height:auto;
   max-width:100%;
   max-height:100%;
}

Then use some media queries to check your orientation and that's it!

@media (orientation: landscape) { img { height:100%; } }
@media (orientation: portrait) { img { width:100%; } }

You will always get an image that scales to fit the screen, never loses aspect ratio, never scales larger than the screen, never clips or overflows.

To learn more about these media queries, you can read MDN's specs.

Centering

To center your image horizontally and vertically, just use the flex box model. Use a parent div set to 100% width and height, like so:

div.parent {
   display:flex;
   position:fixed;
   left:0px;
   top:0px;
   width:100%;
   height:100%;
   justify-content:center;
   align-items:center;
}

With the parent div's display set to flex, the element is now ready to use the flex box model. The justify-content property sets the horizontal alignment of the flex items. The align-items property sets the vertical alignment of the flex items.

Conclusion

I too had wanted these exact requirements and had scoured the web for a pure CSS solution. Since none of the answers here fulfilled all of your requirements, either with workarounds or settling upon sacrificing a requirement or two, this solution really is the most straightforward for your goals; as it fulfills all of your requirements with pure CSS.

EDIT: The accepted answer will only appear to work if your images are large. Try using small images and you will see that they can never be larger than their original size.

If you're using SQL Server, you could add three calculated fields to your table:

Sales (saleID INT, amount INT, created DATETIME)

ALTER TABLE dbo.Sales
  ADD SaleYear AS YEAR(Created) PERSISTED
ALTER TABLE dbo.Sales
  ADD SaleMonth AS MONTH(Created) PERSISTED
ALTER TABLE dbo.Sales
  ADD SaleDay AS DAY(Created) PERSISTED

and now you could easily group by, order by etc. by day, month or year of the sale:

SELECT SaleDay, SUM(Amount)
FROM dbo.Sales
GROUP BY SaleDay

Those calculated fields will always be kept up to date (when your "Created" date changes), they're part of your table, they can be used just like regular fields, and can even be indexed (if they're "PERSISTED") - great feature that's totally underused, IMHO.

Activity.runOnUiThread() does not work for me. I worked around this issue by creating a regular thread this way:

public class PullTasksThread extends Thread {
   public void run () {
      Log.d(Prefs.TAG, "Thread run...");
   }
}

and calling it from the GL update this way:

new PullTasksThread().start();

Respectfully to all those saying you can't insert a parameter in the middle of an alias I just tested it and found that it did work.

alias mycommand = "python3 "$1" script.py --folderoutput RESULTS/"

when I then ran mycommand foobar it worked exactly as if I had typed the command out longhand.

I added

"types": [ 
   "node"
]

in my tsconfig file and its worked for me tsconfig.json file look like

  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "baseUrl": "./",
    "module": "es2015",
    "types": [ 
      "node",
      "underscore"
    ]
  },  

As Shafik already wrote you need to use the right format because scanf gets you a char. Don't hesitate to look here if u aren't sure about the usage: http://www.cplusplus.com/reference/cstdio/printf/

Hint: It's faster/nicer to write x=x+1; the shorter way: x++;

Sorry for answering what's answered just wanted to give him the link - the site was really useful to me all the time dealing with C.

Another way is from command line, using the osql:

OSQL -S SERVERNAME -E -i thequeryfile.sql -o youroutputfile.txt

This can be used from a BAT file and shceduled by a windows user to authenticated.

Similar situation. It was working. Then, I started to include pytables. At first view, no reason to errors. I decided to use another function, that has a domain constraint (elipse) and received the following error:

TypeError: 'numpy.float64' object cannot be interpreted as an integer

or

TypeError: 'numpy.float64' object is not iterable

The crazy thing: the previous function I was using, no code changed, started to return the same error. My intermediary function, already used was:

def MinMax(x, mini=0, maxi=1)
    return max(min(x,mini), maxi)

The solution was avoid numpy or math:

def MinMax(x, mini=0, maxi=1)
    x = [x_aux if x_aux > mini else mini for x_aux in x]
    x = [x_aux if x_aux < maxi else maxi for x_aux in x]
    return max(min(x,mini), maxi)

Then, everything calm again. It was like one library possessed max and min!

For SQL Server 2008, the best and index friendly way is

DELETE from Table WHERE Date > CAST(GETDATE() as DATE);

For prior SQL Server versions, date maths will work faster than a convert to varchar. Even converting to varchar can give you the wrong result, because of regional settings.

DELETE from Table WHERE Date > DATEDIFF(d, 0, GETDATE());

_{Note: it is unnecessary to wrap the DATEDIFF with another DATEADD}

Instead of using EXISTS and COUNT just use @@ROWCOUNT:

select product, price from table1 where project = 1

IF @@ROWCOUNT = 0
BEGIN
    select product, price from table1 where customer = 2

    IF @@ROWCOUNT = 0
    select product, price from table1 where company = 3
END

CONCAT, as stated, is not supported prior to SQL Server 2012. However you can concatenate simply using the + operator as suggested. But beware, this operator will throw an error if the first operand is a number since it thinks will be adding and not concatenating. To resolve this issue just add '' in front. For example

someNumber + 'someString' + .... + lastVariableToConcatenate

will raise an error BUT '' + someNumber + 'someString' + ...... will work just fine.

Also, if there are two numbers to be concatenated make sure you add a '' between them, like so

.... + someNumber + '' + someOtherNumber + .....

Check with your firewall expert. They open the firewall for PROD servers so there is no need to use the Proxy.

Thanks your tip helped me solve my problem:

Had to to set the Credentials in two locations to get past the 407 error:

HttpWebRequest webRequest = WebRequest.Create(uirTradeStream) as HttpWebRequest;
webRequest.Proxy = WebRequest.DefaultWebProxy;
webRequest.Credentials = new NetworkCredential("user", "password", "domain");
webRequest.Proxy.Credentials = new NetworkCredential("user", "password", "domain");

and voila!

If anyone wanted to Add DataTable as a source of gridview then--

DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("column1"));
dt.Columns.Add(new DataColumn("column2"));

DataRow dr = dt.NewRow();
dr[0] = "column1 Value";
dr[1] = "column2 Value";

dt.Rows.Add(dr);

dataGridView1.DataSource = dt;

SELECT COUNT(*) FROM bla WHERE Position = 'Manager'

Without jQuery:

String.prototype.width = function (fontSize) {
    var el,
        f = fontSize + " px arial" || '12px arial';
    el = document.createElement('div');
    el.style.position = 'absolute';
    el.style.float = "left";
    el.style.whiteSpace = 'nowrap';
    el.style.visibility = 'hidden';
    el.style.font = f;
    el.innerHTML = this;
    el = document.body.appendChild(el);
    w = el.offsetWidth;
    el.parentNode.removeChild(el);
    return w;
}

// Usage
"MyString".width(12);

With vanilla JavaScript, you could easily take the params (location.search), get the substring (without the ?) and turn it into an array, by splitting it by '&'.

As you iterate through urlParams, you could then split the string again with '=' and add it to the 'params' object as object[elmement[0]] = element[1]. Super simple and easy to access.

http://www.website.com/?error=userError&type=handwritten

            var urlParams = location.search.substring(1).split('&'),
                params = {};

            urlParams.forEach(function(el){
                var tmpArr = el.split('=');
                params[tmpArr[0]] = tmpArr[1];
            });


            var error = params['error'];
            var type = params['type'];

Use \x Example from postgres manual:

on Mac OS X (BSD find): Same as accepted answer, the .*/ prefix is needed to match a complete path:

$ find -E . -regex ".*/[a-f0-9\-]{36}.jpg"

man find says -E uses extended regex support

With current methods available in Linq it looks quite ugly:

var tasks = items.Select(
    async item => new
    {
        Item = item,
        IsValid = await IsValid(item)
    });
var tuples = await Task.WhenAll(tasks);
var validItems = tuples
    .Where(p => p.IsValid)
    .Select(p => p.Item)
    .ToList();

Hopefully following versions of .NET will come up with more elegant tooling to handle collections of tasks and tasks of collections.

The universal tool for string formatting, sprintf:

$stamp = sprintf('%s%02s', $year, $month);

http://php.net/manual/en/function.sprintf.php

DataSet is collection of DataTables.... you can get the datatable from DataSet as below.

//here ds is dataset
DatTable dt = ds.Table[0]; /// table of dataset

What is null?

It is nothing.

Is null an instance of anything?

No as it is nothing It can't be instance of any thing.

What set does null belong to?

No any set

How is it represented in the memory?

If some reference points to it like:

Object o=new Object();

In heap memory some space assigned to new created object. And o will point to that assigned space in memory.

Now o=null;

This means now o will not point to that memory space of object.

There are precious few immutable collections in the current framework. I can think of one relatively pain-free option in .NET 3.5:

Use Enumerable.ToLookup() - the Lookup<,> class is immutable (but multi-valued on the rhs); you can do this from a Dictionary<,> quite easily:

    Dictionary<string, int> ids = new Dictionary<string, int> {
      {"abc",1}, {"def",2}, {"ghi",3}
    };
    ILookup<string, int> lookup = ids.ToLookup(x => x.Key, x => x.Value);
    int i = lookup["def"].Single();

I can't speak for the 2nd or 3rd, but if you install Node first, Sublime-HTMLPrettify works pretty well. You have to setup your own key shortcut once it is installed. One thing I noticed on Windows, you may need to edit your path for Node in the %PATH% variable if it is already long (I think the limit is 1024 for the %PATH% variable, and anything after that is ignored.)

There is a Windows bug, but in the issues there is a fix for it. You'll need to edit the HTMLPrettify.py file - https://github.com/victorporof/Sublime-HTMLPrettify/issues/12

I've a workaround for NullPointerException when remove fragment in on DestoryView, Just put your code in onStop() not onDestoryView. It works fine!

@Override
public void onStop() {
    super.onStop();
    if (mMap != null) {
        MainActivity.fragmentManager.beginTransaction()
                .remove(MainActivity.fragmentManager.findFragmentById(R.id.location_map)).commit();
        mMap = null;
    }
}

Request.RawUrl

SWIFT 4.2

Sometimes this happened just because there is space in slug OR absence of URL encoding for parameters passing through API URL.

let myString = self.slugValue
                let csCopy = CharacterSet(bitmapRepresentation: CharacterSet.urlPathAllowed.bitmapRepresentation)
                let escapedString = myString!.addingPercentEncoding(withAllowedCharacters: csCopy)!
                //always "info:hello%20world"
                print(escapedString)

NOTE : Don't forget to explore about bitmapRepresentation.

In addition to xzyfer's answer

The function

function custom_unset(&$array=array(), $key=0) {
    if(isset($array[$key])){

        // remove item at index
        unset($array[$key]);

        // 'reindex' array
        $array = array_values($array);

        //alternatively
        //$array = array_merge($array); 

    }
    return $array;
}

Use

$my_array=array(
    0=>'test0', 
    1=>'test1', 
    2=>'test2'
);

custom_unset($my_array, 1);

Result

 array(2) {
    [0]=>
    string(5) "test0"
    [1]=>
    string(5) "test2"
  }

    var p=document.getElementById('childId').parentNode;
    var c=document.getElementById('childId');
    p.removeChild(c);
    alert('Deleted');

p is parent node and c is child node
parentNode is a JavaScript variable which contains parent reference

Easy to understand

"inappropriate ioctl for device" is the error string for the ENOTTY error. It used to be triggerred primarily by attempts to configure terminal properties (e.g. echo mode) on a file descriptor that was no terminal (but, say, a regular file), hence ENOTTY. More generally, it is triggered when doing an ioctl on a device that does not support that ioctl, hence the error string.

To find out what ioctl is being made that fails, and on what file descriptor, run the script under strace/truss. You'll recognize ENOTTY, followed by the actual printing of the error message. Then find out what file number was used, and what open() call returned that file number.

An alternative solution would be to use the Url helper object to set the href attribute of an <a> tag like:

<a href="@Url.Action("Details", "Product",new { id=item.ID }) )">Details</a>

You need to use the .toFixed() method

It takes as a parameter the number of digits to show after the decimal point.

$(document).ready(function() {
  $('.add').click(function() {
     var value = parseFloat($('#total').text()) + parseFloat($(this).data('amount'))/100
     $('#total').text( value.toFixed(2) );
  });
})

You can use following SQL to restore if you've already created database

RESTORE DATABASE [YourDB]
FROM DISK = 'C:\YourDB.bak'
WITH MOVE 'YourDB' TO 'C:\YourDB.mdf',
MOVE 'YourDB_Log' TO 'C:\YourDB.ldf', REPLACE

The scanner can also use delimiters other than whitespace.

Easy example from Scanner API:

 String input = "1 fish 2 fish red fish blue fish";

 // \\s* means 0 or more repetitions of any whitespace character 
 // fish is the pattern to find
 Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*");

 System.out.println(s.nextInt());   // prints: 1
 System.out.println(s.nextInt());   // prints: 2
 System.out.println(s.next());      // prints: red
 System.out.println(s.next());      // prints: blue

 // don't forget to close the scanner!!
 s.close(); 

The point is to understand the regular expressions (regex) inside the Scanner::useDelimiter. Find an useDelimiter tutorial here.

To start with regular expressions here you can find a nice tutorial.

RFC 2616, section 14.9.1:

Indicates that all or part of the response message is intended for a single user and MUST NOT be cached by a shared cache...A private (non-shared) cache MAY cache the response.

Browsers could use this information. Of course, the current "user" may mean many things: OS user, a browser user (e.g. Chrome's profiles), etc. It's not specified.

For me, a more concrete example of Cache-Control: private is that proxy servers (which typically have many users) won't cache it. It is meant for the end user, and no one else.

FYI, the RFC makes clear that this does not provide security. It is about showing the correct content, not securing content.

This usage of the word private only controls where the response may be cached, and cannot ensure the privacy of the message content.

Something simple like this can be done using subqueries in the select clause:

select ((select sum(hours) from resource) +
        (select sum(hours) from projects-time)
       ) as totalHours

For such a simple query as this, such a subselect is reasonable.

In some databases, you might have to add from dual for the query to compile.

If you want to output each individually:

select (select sum(hours) from resource) as ResourceHours,
       (select sum(hours) from projects-time) as ProjectHours

If you want both and the sum, a subquery is handy:

select ResourceHours, ProjectHours, (ResourceHours+ProjecctHours) as TotalHours
from (select (select sum(hours) from resource) as ResourceHours,
             (select sum(hours) from projects-time) as ProjectHours
     ) t

try this

= f.input :title, :as => :hidden, :input_html => { :value => "some value" }

By lines I assume you mean rows in the table person. What you're looking for is:

select p.name
from   person p
where  p.name LIKE '%A%'; --contains the character 'A'

The above is case sensitive. For a case insensitive search, you can do:

select p.name
from   person p
where  UPPER(p.name) LIKE '%A%'; --contains the character 'A' or 'a'

For the special character, you can do:

select p.name
from   person p
where  p.name LIKE '%'||chr(8211)||'%'; --contains the character chr(8211)

The LIKE operator matches a pattern. The syntax of this command is described in detail in the Oracle documentation. You will mostly use the % sign as it means match zero or more characters.

You already have a process bound to the default port (8000). If you already ran the same module before, it is most likely that process still bound to the port. Try and locate the other process first:

$ ps -fA | grep python
  501 81651 12648   0  9:53PM ttys000    0:00.16 python -m SimpleHTTPServer

The command arguments are included, so you can spot the one running SimpleHTTPServer if more than one python process is active. You may want to test if http://localhost:8000/ still shows a directory listing for local files.

The second number is the process number; stop the server by sending it a signal:

kill 81651

This sends a standard SIGTERM signal; if the process is unresponsive you may have to resort to tougher methods like sending a SIGKILL (kill -s KILL <pid> or kill -9 <pid>) signal instead. See Wikipedia for more details.

Alternatively, run the server on a different port, by specifying the alternative port on the command line:

$ python -m SimpleHTTPServer 8910
Serving HTTP on 0.0.0.0 port 8910 ...

then access the server as http://localhost:8910; where 8910 can be any number from 1024 and up, provided the port is not already taken.

If you can use Python, it is even easier if you have the pyopenssl module. Here it is:

from OpenSSL import crypto

# May require "" for empty password depending on version

with open("push.p12", "rb") as file:
    p12 = crypto.load_pkcs12(file.read(), "my_passphrase")

# PEM formatted private key
print crypto.dump_privatekey(crypto.FILETYPE_PEM, p12.get_privatekey())

# PEM formatted certificate
print crypto.dump_certificate(crypto.FILETYPE_PEM, p12.get_certificate())

While the other posters addressed why is True does what it does, I wanted to respond to this part of your post:

I thought Python treats anything with value as True. Why is this happening?

Coming from Java, I got tripped up by this, too. Python does not treat anything with a value as True. Witness:

if 0:
    print("Won't get here")

This will print nothing because 0 is treated as False. In fact, zero of any numeric type evaluates to False. They also made decimal work the way you'd expect:

from decimal import *
from fractions import *

if 0 or 0.0 or 0j or Decimal(0) or Fraction(0, 1):
    print("Won't get here")

Here are the other value which evaluate to False:

if None or False or '' or () or [] or {} or set() or range(0):
    print("Won't get here")

I tried to convert ddmmyy format to date("Y-m-d" format but was not working when I directly pass ddmmyy =date('dmy')

then realized it has to be in yyyy-mm-dd format so. used substring to organize

$strParam = '20'.substr($_GET['date'], 4, 2).'-'.substr($_GET['date'], 2, 2).'-'.substr($_GET['date'], 0, 2);  

then passed to date("Y-m-d",strtotime($strParam));

it worked!

Simple solution to drop all the table at once from terminal.

This involved few steps inside your mysql shell (not a one step solution though), this worked me and saved my day.

Worked for Server version: 5.6.38 MySQL Community Server (GPL)

Steps I followed:

 1. generate drop query using concat and group_concat.
 2. use database
 3. turn off / disable foreign key constraint check (SET FOREIGN_KEY_CHECKS = 0;), 
 4. copy the query generated from step 1
 5. re enable foreign key constraint check (SET FOREIGN_KEY_CHECKS = 1;)
 6. run show table

I had a problem with mime types and where making tests for few file types. It looks like each browser sends it's variation of a mime type for a specific file. I was trying to upload mp3 and zip files with open source php class, that what I have found:

• Firefox (mp3): audio/mpeg
• Firefox (zip): application/zip
• Chrome (mp3): audio/mp3
• Chrome (zip): application/octet-stream
• Opera (mp3): audio/mp3
• Opera (zip): application/octet-stream
• IE (mp3): audio/mpeg
• IE (zip): application/x-zip-compressed

So if you need several file types to upload, you better make some tests so that every browser could upload a file and pass mime type check.

Easiest way I found to receive current time in milliseconds in MySql:

SELECT (UNIX_TIMESTAMP(NOW(3)) * 1000)

Since MySql 5.6.

For those coming across this in the future:

If you would like to see a list of relations for several schemas:

$psql mydatabase
mydatabase=# SET search_path TO public, usa;   #schema examples
SET
mydatabase=# \dt
              List of relations
 Schema |      Name       | Type  |  Owner
--------+-----------------+-------+----------
 public | counties        | table | postgres
 public | spatial_ref_sys | table | postgres
 public | states          | table | postgres
 public | us_cities       | table | postgres
 usa    | census2010      | table | postgres

DATE_FORMAT returns a string, so you're using two strings in your BETWEEN clause, which isn't going to work as you expect.

Instead, convert the date to your format in the SELECT and do the BETWEEN for the actual dates. For example,

SELECT DATE_FORMAT(create_date, '%m/%d/%y') as create_date_formatted
FROM table
WHERE create_date BETWEEN (CURDATE() - INTERVAL 30 DAY) AND CURDATE()

I think that this should work:

.element {
   -webkit-transition: all .3s;
   -moz-transition: all .3s;
   -o-transition: all .3s;
   transition: all .3s;
}

Do same as you did in file1.c In file2.c:

#include <stdio.h> 

extern int i;  /*This declare that i is an int variable which is defined in some other file*/

int main(void)
{
/* your code*/

If you use int i; in file2.c under main() then i will be treated as local auto variable not the same as defined in file1.c

Note that if there are ties in top 10 values, you will only get the top 10 rows, not the top 10 values with the answers provided. Ex: if the top 5 values are 10, 11, 12, 13, 14, 15 but your data contains 10, 10, 11, 12, 13, 14, 15 you will only get 10, 10, 11, 12, 13, 14 as your top 5 with a LIMIT

Here is a solution which will return more than 10 rows if there are ties but you will get all the rows where some_value_column is technically in the top 10.

select
  *
from
  (select
     *,
     rank() over (order by some_value_column desc) as my_rank
  from mytable) subquery
where my_rank <= 10

I got the same error from having two references to different versions of jQuery.

In my master page:

Use JSON module for multidimensional arrays, e.g.

import json
with open(filename, 'w') as f:
   json.dump(myndarray.tolist(), f)

More based on the feeling, but this is the error you would get if you missed to declare a bean in the context configuration, so try adding

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="maxUploadSize" value="10000000"/>
</bean>

var input = '/var/www/site/Brand new document.docx';

//remove space
input = input.replace(/\s/g, '');

//make string lower
input = input.toLowerCase();

alert(input);

Click here for working example

You need to set with only C:\Program Files\Java\jdk1.8.0_12.

And check with using new cmd. It will be updated

function add(){
    var first=parseFloat($("#first").val());
    var second=parseFloat($("#second").val());
    $("#result").val(+(first+second).toFixed(2));
}

DEMO.

It's a small space optimization.

When you say

const int foo = 42;

You're not defining a constant, but creating a read-only variable. The compiler is smart enough to use 42 whenever it sees foo, but it will also allocate space in the initialized data area for it. This is done because, as defined, foo has external linkage. Another compilation unit can say:

extern const int foo;

To get access to its value. That's not a good practice since that compilation unit has no idea what the value of foo is. It just knows it's a const int and has to reload the value from memory whenever it is used.

Now, by declaring that it is static:

static const int foo = 42;

The compiler can do its usual optimization, but it can also say "hey, nobody outside this compilation unit can see foo and I know it's always 42 so there is no need to allocate any space for it."

I should also note that in C++, the preferred way to prevent names from escaping the current compilation unit is to use an anonymous namespace:

namespace {
    const int foo = 42; // same as static definition above
}

Note that, for PIPE being any command or sequence of commands, then:

if PIPE ; then
  # do one thing if PIPE returned with zero status ($?=0)
else 
  # do another thing if PIPE returned with non-zero status ($?!=0), e.g. error
fi 

For the record, [ expr ] is a shell builtin^† shorthand for test expr.

Since grep returns with status 0 in case of a match, and non-zero status in case of no matches, you can use:

if grep -lq '^MYSQL_ROLE=master' ; then 
  # do one thing 
else 
  # do another thing
fi 

Note the use of -l which only cares about the file having at least one match (so that grep returns as soon as it finds one match, without needlessly continuing to parse the input file.)

^†on some platforms [ expr ] is not a builtin, but an actual executable /bin/[ (whose last argument will be ]), which is why [ expr ] should contain blanks around the square brackets, and why it must be followed by one of the command list separators (;, &&, ||, |, &, newline)

The biggest benefit of lambda expressions and anonymous functions is the fact that they allow the client (programmer) of a library/framework to inject functionality by means of code in the given library/framework ( as it is the LINQ, ASP.NET Core and many others ) in a way that the regular methods cannot. However, their strength is not obvious for a single application programmer but to the one that creates libraries that will be later used by others who will want to configure the behaviour of the library code or the one that uses libraries. So the context of effectively using a lambda expression is the usage/creation of a library/framework.

Also since they describe one-time usage code they don't have to be members of a class where that will led to more code complexity. Imagine to have to declare a class with unclear focus every time we wanted to configure the operation of a class object.

private static String getPreviousMonthDate(Date date){
    final SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");

    Calendar cal = Calendar.getInstance();  
    cal.setTime(date);  
    cal.set(Calendar.DAY_OF_MONTH, 1);  
    cal.add(Calendar.DATE, -1);

    Date preMonthDate = cal.getTime();  
    return format.format(preMonthDate);
}


private static String getPreToPreMonthDate(Date date){
    final SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");

    Calendar cal = Calendar.getInstance();  
    cal.setTime(date);  
    cal.add(Calendar.MONTH, -1);  
    cal.set(Calendar.DAY_OF_MONTH,1);  
    cal.add(Calendar.DATE, -1);  

    Date preToPreMonthDate = cal.getTime();  
    return format.format(preToPreMonthDate);
}

• utf8 is MySQL's older, flawed implementation of UTF-8 which is in the process of being deprecated.
• utf8mb4 is what they named their fixed UTF-8 implementation, and is what you should use right now.

In their flawed version, only characters in the first 64k character plane - the basic multilingual plane - work, with other characters considered invalid. The code point values within that plane - 0 to 65535 (some of which are reserved for special reasons) can be represented by multi-byte encodings in UTF-8 of up to 3 bytes, and MySQL's early version of UTF-8 arbitrarily decided to set that as a limit. At no point was this limitation a correct interpretation of the UTF-8 rules, because at no point was UTF-8 defined as only allowing up to 3 bytes per character. In fact, the earliest definitions of UTF-8 defined it as having up to 6 bytes (since revised to 4). MySQL's original version was always arbitrarily crippled.

Back when MySQL released this, the consequences of this limitation weren't too bad as most Unicode characters were in that first plane. Since then, more and more newly defined character ranges have been added to Unicode with values outside that first plane. Unicode itself defines 17 planes, though so far only 7 of these are used.

In an effort not to break old code making any particular assumptions, MySQL retained the broken implementation and called the newer, fixed version utf8mb4. This has led to some confusion with the name being misinterpreted as if it's some kind of extension to UTF-8 or alternative form of UTF-8, rather than MySQL's implementation of the true UTF-8.

Future versions of MySQL will eventually phase out the older version, and for now it can be considered deprecated. For the foreseeable future you need to use utf8mb4 to ensure correct UTF-8 encoding. After sufficient time has passed, the current utf8 will be removed, and at some future date utf8 will rise again, this time referring to the fixed version, though utf8mb4 will continue to unambiguously refer to the fixed version.

Here's the other one, particularly useful to convert the multiple columns to string instead of just single column:

In [76]: import numpy as np
In [77]: import pandas as pd
In [78]: df = pd.DataFrame({
    ...:     'A': [20, 30.0, np.nan],
    ...:     'B': ["a45a", "a3", "b1"],
    ...:     'C': [10, 5, np.nan]})
    ...: 

In [79]: df.dtypes ## Current datatype
Out[79]: 
A    float64
B     object
C    float64
dtype: object

## Multiple columns string conversion
In [80]: df[["A", "C"]] = df[["A", "C"]].astype(str) 

In [81]: df.dtypes ## Updated datatype after string conversion
Out[81]: 
A    object
B    object
C    object
dtype: object

It's because there can only be one definition of A::a that all the translation units use.

If you performed static int a = 3; in a class in a header included in all a translation units then you'd get multiple definitions. Therefore, non out-of-line definition of a static is forcibly made a compiler error.

Using static inline or static const remedies this. static inline only concretises the symbol if it is used in the translation unit and ensures the linker only selects and leaves one copy if it's defined in multiple translation units due to it being in a comdat group. const at file scope makes the compiler never emit a symbol because it's always substituted immediately in the code unless extern is used, which is not permitted in a class.

One thing to note is static inline int b; is treated as a definition whereas static const int b or static const A b; are still treated as a declaration and must be defined out-of-line if you don't define it inside the class. Interestingly static constexpr A b; is treated as a definition, whereas static constexpr int b; is an error and must have an initialiser (this is because they now become definitions and like any const/constexpr definition at file scope, they require an initialiser which an int doesn't have but a class type does because it has an implicit = A() when it is a definition -- clang allows this but gcc requires you to explicitly initialise or it is an error. This is not a problem with inline instead). static const A b = A(); is not allowed and must be constexpr or inline in order to permit an initialiser for a static object with class type i.e to make a static member of class type more than a declaration. So yes in certain situations A a; is not the same as explicitly initialising A a = A(); (the former can be a declaration but if only a declaration is allowed for that type then the latter is an error. The latter can only be used on a definition. constexpr makes it a definition). If you use constexpr and specify a default constructor then the constructor will need to be constexpr

#include<iostream>

struct A
{
    int b =2;
    mutable int c = 3; //if this member is included in the class then const A will have a full .data symbol emitted for it on -O0 and so will B because it contains A.
    static const int a = 3;
};

struct B {
    A b;
    static constexpr A c; //needs to be constexpr or inline and doesn't emit a symbol for A a mutable member on any optimisation level
};

const A a;
const B b;

int main()
{
    std::cout << a.b << b.b.b;
    return 0;
}

A static member is an outright file scope declaration extern int A::a; (which can only be made in the class and out of line definitions must refer to a static member in a class and must be definitions and cannot contain extern) whereas a non-static member is part of the complete type definition of a class and have the same rules as file scope declarations without extern. They are implicitly definitions. So int i[]; int i[5]; is a redefinition whereas static int i[]; int A::i[5]; isn't but unlike 2 externs, the compiler will still detect a duplicate member if you do static int i[]; static int i[5]; in the class.

Coversion from string to double can be achieved by using the 'strtod()' function from the library 'stdlib.h'

#include <iostream>
#include <stdlib.h>
int main () 
{
    std::string data="20.9";
    double value = strtod(data.c_str(), NULL);
    std::cout<<value<<'\n';
    return 0;
}

You can try this function which is more simple.

function getWorkingDays($startDate, $endDate)
{
    $begin = strtotime($startDate);
    $end   = strtotime($endDate);
    if ($begin > $end) {

        return 0;
    } else {
        $no_days  = 0;
        while ($begin <= $end) {
            $what_day = date("N", $begin);
            if (!in_array($what_day, [6,7]) ) // 6 and 7 are weekend
                $no_days++;
            $begin += 86400; // +1 day
        };

        return $no_days;
    }
}

With CSS3 flexbox. Simple.

ul {
  display: flex;
  justify-content: center;
}

ul li {
  padding: 0 8px;
}

It would be easier to use XML in SQL Server to insert multiple rows otherwise it becomes very tedious.

View full article with code explanations here http://www.cyberminds.co.uk/blog/articles/how-to-insert-multiple-rows-in-sql-server.aspx

Copy the following code into sql server to view a sample.

declare @test nvarchar(max)

set @test = '<topic><dialog id="1" answerId="41">
        <comment>comment 1</comment>
        </dialog>
    <dialog id="2" answerId="42" >
    <comment>comment 2</comment>
        </dialog>
    <dialog id="3" answerId="43" >
    <comment>comment 3</comment>
        </dialog>
    </topic>'

declare @testxml xml
set @testxml = cast(@test as xml)
declare @answerTemp Table(dialogid int, answerid int, comment varchar(1000))

insert @answerTemp
SELECT  ParamValues.ID.value('@id','int') ,
ParamValues.ID.value('@answerId','int') ,
ParamValues.ID.value('(comment)[1]','VARCHAR(1000)')
FROM @testxml.nodes('topic/dialog') as ParamValues(ID)

1. Making it static could fix this issue.
2. Reference to the main thread in other thread and making that variable visible

var v = "全名";
$("#div").html(v); //display as "??"
$("#div").text(v); //display as "全名"

text() – This method sets or returns the text content of elements selected. html() – This method sets or returns the content of elements selected. Refer example here : https://www.tutorialspoint.com/online_jquery_editor.php

Are you asking for renaming column itself or capitalise the data inside column? If its data you've to change, then use this:

UPDATE [yourtable]
SET word=UPPER(LEFT(word,1))+LOWER(SUBSTRING(word,2,LEN(word)))

If you just wanted to change it only for displaying and do not need the actual data in table to change:

SELECT UPPER(LEFT(word,1))+LOWER(SUBSTRING(word,2,LEN(word))) FROM [yourtable]

Hope this helps.

EDIT: I realised about the '-' so here is my attempt to solve this problem in a function.

CREATE FUNCTION [dbo].[CapitalizeFirstLetter]
(
--string need to format
@string VARCHAR(200)--increase the variable size depending on your needs.
)
RETURNS VARCHAR(200)
AS

BEGIN
--Declare Variables
DECLARE @Index INT,
@ResultString VARCHAR(200)--result string size should equal to the @string variable size
--Initialize the variables
SET @Index = 1
SET @ResultString = ''
--Run the Loop until END of the string

WHILE (@Index <LEN(@string)+1)
BEGIN
IF (@Index = 1)--first letter of the string
BEGIN
--make the first letter capital
SET @ResultString =
@ResultString + UPPER(SUBSTRING(@string, @Index, 1))
SET @Index = @Index+ 1--increase the index
END

-- IF the previous character is space or '-' or next character is '-'

ELSE IF ((SUBSTRING(@string, @Index-1, 1) =' 'or SUBSTRING(@string, @Index-1, 1) ='-' or SUBSTRING(@string, @Index+1, 1) ='-') and @Index+1 <> LEN(@string))
BEGIN
--make the letter capital
SET
@ResultString = @ResultString + UPPER(SUBSTRING(@string,@Index, 1))
SET
@Index = @Index +1--increase the index
END
ELSE-- all others
BEGIN
-- make the letter simple
SET
@ResultString = @ResultString + LOWER(SUBSTRING(@string,@Index, 1))
SET
@Index = @Index +1--incerase the index
END
END--END of the loop

IF (@@ERROR
<> 0)-- any error occur return the sEND string
BEGIN
SET
@ResultString = @string
END
-- IF no error found return the new string
RETURN @ResultString
END

So then the code would be:

UPDATE [yourtable]
SET word=dbo.CapitalizeFirstLetter([STRING TO GO HERE])

Use float roundf(float x).

"The round functions round their argument to the nearest integer value in floating-point format, rounding halfway cases away from zero, regardless of the current rounding direction." C11dr §7.12.9.5

#include <math.h>
float y = roundf(x * 100.0f) / 100.0f; 

Depending on your float implementation, numbers that may appear to be half-way are not. as floating-point is typically base-2 oriented. Further, precisely rounding to the nearest 0.01 on all "half-way" cases is most challenging.

void r100(const char *s) {
  float x, y;
  sscanf(s, "%f", &x);
  y = round(x*100.0)/100.0;
  printf("%6s %.12e %.12e\n", s, x, y);
}

int main(void) {
  r100("1.115");
  r100("1.125");
  r100("1.135");
  return 0;
}

 1.115 1.115000009537e+00 1.120000004768e+00  
 1.125 1.125000000000e+00 1.129999995232e+00
 1.135 1.134999990463e+00 1.139999985695e+00

Although "1.115" is "half-way" between 1.11 and 1.12, when converted to float, the value is 1.115000009537... and is no longer "half-way", but closer to 1.12 and rounds to the closest float of 1.120000004768...

"1.125" is "half-way" between 1.12 and 1.13, when converted to float, the value is exactly 1.125 and is "half-way". It rounds toward 1.13 due to ties to even rule and rounds to the closest float of 1.129999995232...

Although "1.135" is "half-way" between 1.13 and 1.14, when converted to float, the value is 1.134999990463... and is no longer "half-way", but closer to 1.13 and rounds to the closest float of 1.129999995232...

If code used

y = roundf(x*100.0f)/100.0f;

Although "1.135" is "half-way" between 1.13 and 1.14, when converted to float, the value is 1.134999990463... and is no longer "half-way", but closer to 1.13 but incorrectly rounds to float of 1.139999985695... due to the more limited precision of float vs. double. This incorrect value may be viewed as correct, depending on coding goals.

After reading Java 7 Update 21 Security Improvements in Detail mention..

With the introduced changes it is most likely that no end-user is able to run your application when they are either self-signed or unsigned.

..I was wondering how this would go for loose class files - the 'simplest' applets of all.

Local file system

Your security settings have blocked a local application from running

That is the dialog seen for an applet consisting of loose class files being loaded off the local file system when the JRE is set to the default 'High' security setting.

Note that a slight quirk of the JRE only produced that on point 3 of.

1. Load the applet page to see a broken applet symbol that leads to an empty console.
   Open the Java settings and set the level to Medium.
   Close browser & Java settings.
2. Load the applet page to see the applet.
   Open the Java settings and set the level to High.
   Close browser & Java settings.
3. Load the applet page to see a broken applet symbol & the above dialog.

Internet

If you load the simple applet (loose class file) seen at this resizable applet demo off the internet - which boasts an applet element of:

<applet
    code="PlafChanger.class"
    codebase="."
    alt="Pluggable Look'n'Feel Changer appears here if Java is enabled"
    width='100%'
    height='250'>
<p>Pluggable Look'n'Feel Changer appears here in a Java capable browser.</p>
</applet>

It also seems to load successfully. Implying that:-

Applets loaded from the local file system are now subject to a stricter security sandbox than those loaded from the internet or a local server.

Security settings descriptions

As of Java 7 update 51.

• Very High: Most secure setting - Only Java applications identified by a non-expired certificate from a trusted authority will be allowed to run.
• High (minimum recommended): Java applications identified by a certificate from a trusted authority will be allowed to run.
• Medium - All Java applications will be allowed to run after presenting a security prompt.

This can be easily handled with pydantic, as it already has this functionality built-in.

Option 1: normal way

from pydantic import BaseModel

class testclass(BaseModel):
    value1: str = "a"
    value2: str = "b"

test = testclass()

>>> print(test.json(indent=4))
{
    "value1": "a",
    "value2": "b"
}

Option 2: using pydantic's dataclass

import json
from pydantic.dataclasses import dataclass
from pydantic.json import pydantic_encoder

@dataclass
class testclass:
    value1: str = "a"
    value2: str = "b"

test = testclass()
>>> print(json.dumps(test, indent=4, default=pydantic_encoder))
{
    "value1": "a",
    "value2": "b"
}

Try this. hope this will help.

    String cls0;
    String cls1;

    Scanner in = new Scanner(System.in);  
    System.out.println("Enter a string");  
    cls0 = in.nextLine();  

    System.out.println("Enter a string");  
    cls1 = in.nextLine(); 

You should be able to use the variable name directly

ansible_ssh_host

Or you can go through hostvars without having to specify the host literally by using the magic variable inventory_hostname

hostvars[inventory_hostname].ansible_ssh_host

You can escape (this is how this principle is called) the double quotes by prefixing them with another double quote. You can put them in a string as follows:

Dim MyVar as string = "some text ""hello"" "

This will give the MyVar variable a value of some text "hello".

First solution:
1. switch off Xorg access control: xhost +
2. Now start google chrome as normal user "anonymous" :
sudo -i -u anonymous /opt/google/chrome/chrome
3. When done browsing, re-enable Xorg access control:
xhost -
More info : Howto run google-chrome as root

Second solution:
1. Edit the file /opt/google/chrome/google-chrome
2. find exec -a "$0" "$HERE/chrome" "$@"
or exec -a "$0" "$HERE/chrome" "$PROFILE_DIRECTORY_FLAG" \ "$@"
3. change as
exec -a "$0" "$HERE/chrome" "$@" --user-data-dir ”/root/.config/google-chrome”

Third solution:
Run Google Chrome Browser as Root on Ubuntu Linux systems

You can have a pair of extension methods to make this task easier:

public static string ToDelimitedString<T>(this IEnumerable<T> lst, string separator = ", ")
{
    return lst.ToDelimitedString(p => p, separator);
}

public static string ToDelimitedString<S, T>(this IEnumerable<S> lst, Func<S, T> selector, 
                                             string separator = ", ")
{
    return string.Join(separator, lst.Select(selector));
}

So now just:

new int[] { 1, 2, 3, 4, 5 }.ToDelimitedString();

You can use any:

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

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

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

Am I missing something? You can just convert offer_date in the comparison:

SELECT *
FROM offers
WHERE to_char(offer_date, 'YYYYMM') = (SELECT to_date(create_date, 'YYYYMM') FROM customers where id = '12345678') AND
      offer_rate > 0 

**Step1**: Go to xampp/phpMyAdmin/config.inc.php
**Step2**: Search this: $cfg['Servers'][$i]['host'] = '127.0.0.1';
**Step3**: Replace with $cfg['Servers'][$i]['host'] = '127.0.0.1:3307';

Here 3307 will be change  with your mysql port number, in my case it is 3307. Most of the times it will be 3306.

You can check your mysql port number from here : xampp/mysql/bin/my.ini

            txt_Days.Text = hidMonthsDays.Value;

You're looking for axhline (a horizontal axis line). For example, the following will give you a horizontal line at y = 0.5:

import matplotlib.pyplot as plt
plt.axhline(y=0.5, color='r', linestyle='-')
plt.show()

We can do it this way -

mongo db_name --quiet --eval 'DBQuery.shellBatchSize = 2000; db.users.find({}).limit(2000).toArray()' > users.json

The shellBatchSize argument is used to determine how many rows is the mongo client allowed to print. Its default value is 20.

Try to use this code:

.col-lg-3 {
  width: 100%;
}
.input-group {
   width: 200px; // for exemple
   margin: 0 auto;
}

if it didn't work use !important

In my case, I wanted the opposite. I wanted to strip off the last 2 characters in my string. This was pretty simple:

String myString = someString.substring(0, someString.length() - 2);

For me what worked was to add 127.0.0.1 subdomain.localhost to my host file. On OSX that was /etc/hosts. Not sure why that was necessary as I could reach the subdomain from chrome.

Neither <iostream> nor <iostream.h> are standard C header files. Your code is meant to be C++, where <iostream> is a valid header. Use g++ (and a .cpp file extension) for C++ code.

Alternatively, this program uses mostly constructs that are available in C anyway. It's easy enough to convert the entire program to compile using a C compiler. Simply remove #include <iostream> and using namespace std;, and replace cout << endl; with putchar('\n');... I advise compiling using C99 (eg. gcc -std=c99)

Change SUM(billableDuration) AS NumSecondsDelivered to

sum(cast(billableDuration as bigint)) or

sum(cast(billableDuration as numeric(12, 0))) according to your need.

The resultant type of of Sum expression is the same as the data type used. It throws error at time of overflow. So casting the column to larger capacity data type and then using Sum operation works fine.

One more way to do this is:

git config remote.origin.url https://github.com/abc/abc.git

To see the existing URL just do:

git config remote.origin.url

It depends on which Ruby version you use:

Ruby 2.4 and higher:

It just works, as since Ruby v2.4.0 supports Unicode case mapping:

"?????".capitalize #=> ?????

Ruby 2.3 and lower:

"maria".capitalize #=> "Maria"
"?????".capitalize #=> ?????

The problem is, it just doesn't do what you want it to, it outputs ????? instead of ?????.

If you're using Rails there's an easy workaround:

"?????".mb_chars.capitalize.to_s # requires ActiveSupport::Multibyte

Otherwise, you'll have to install the unicode gem and use it like this:

require 'unicode'

Unicode::capitalize("?????") #=> ?????

Ruby 1.8:

Be sure to use the coding magic comment:

#!/usr/bin/env ruby

puts "?????".capitalize

gives invalid multibyte char (US-ASCII), while:

#!/usr/bin/env ruby
#coding: utf-8

puts "?????".capitalize

works without errors, but also see the "Ruby 2.3 and lower" section for real capitalization.

You said that you have an existing list. So I'll go with that.

>>> lst1 = [['a','b','c'], [1,2,3], ['x','y','z']]
>>> lst2 = [1, 2, 3]

Right now you are appending the generator object to your second list.

>>> lst2.append(item[0] for item in lst)
>>> lst2
[1, 2, 3, <generator object <genexpr> at 0xb74b3554>]

But you probably want it to be a list of first items

>>> lst2.append([item[0] for item in lst])
>>> lst2
[1, 2, 3, ['a', 1, 'x']]

Now we appended the list of first items to the existing list. If you'd like to add the items themeselves, not a list of them, to the existing ones, you'd use list.extend. In that case we don't have to worry about adding a generator, because extend will use that generator to add each item it gets from there, to extend the current list.

>>> lst2.extend(item[0] for item in lst)
>>> lst2
[1, 2, 3, 'a', 1, 'x']

or

>>> lst2 + [x[0] for x in lst]
[1, 2, 3, 'a', 1, 'x']
>>> lst2
[1, 2, 3]

Using == to compare two enum values works, because there is only one object for each enum constant.

On a side note, there is actually no need to use == to write null-safe code, if you write your equals() like this:

public useEnums(final SomeEnum a) {
    if (SomeEnum.SOME_ENUM_VALUE.equals(a)) {
        …
    }
    …
}

This is a best practice known as Compare Constants From The Left that you definitely should follow.

Use FirebaseMessaging instead

 FirebaseMessaging.getInstance().getToken()
    .addOnCompleteListener(new OnCompleteListener<String>() {
        @Override
        public void onComplete(@NonNull Task<String> task) {
          if (!task.isSuccessful()) {
            Log.w(TAG, "Fetching FCM registration token failed", task.getException());
            return;
          }

          // Get new FCM registration token
          String token = task.getResult();

          // Log and toast
          String msg = getString(R.string.msg_token_fmt, token);
          Log.d(TAG, msg);
          Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
        }
    });

I thought I would share my findings in case someone is considering a JQuery plugin to do the job.

I gave JQuery Custom Scrollbar a go. It's pretty fancy and does some smooth scrolling (with scrolling inertia) and has loads of parameters you can tweak, but it ended up being a bit too CPU intensive for me (and it adds a fair amount to the DOM).

Now I'm giving Perfect Scrollbar a go. It's simple and lightweight (6KB) and it's doing a decent job so far. It's not CPU intensive at all (as far as I can tell) and adds very little to your DOM. It's only got a couple of parameters to tweak (wheelSpeed and wheelPropagation), but it's all I need and it handles updates to the scrolling content nicely (such as loading images).

P.S. I did have a quick look at JScrollPane, but @simone is right, it's a bit dated now and a PITA.

Use $ne (for "not equal")

db.collection.find({ "fieldToCheck": { $exists: true, $ne: null } })

you can drop the Constraint which is restricting you. If the column has access to other table. suppose a view is accessing the column which you are altering then it wont let you alter the column unless you drop the view. and after making changes you can recreate the view.

In c/cpp there is no shortcut but to initialize all the arrays with the zero subscript.Ex:

  int arr[10] = {0};

But in java there is a magic tool called Arrays.fill() which will fill all the values in an array with the integer of your choice.Ex:

  import java.util.Arrays;

    public class Main
    {
      public static void main(String[] args)
       {
         int ar[] = {2, 2, 1, 8, 3, 2, 2, 4, 2};
         Arrays.fill(ar, 10);
         System.out.println("Array completely filled" +                          
            " with 10\n" + Arrays.toString(ar));
   }
 }

Try Window > Open Perspective > Java Browsing or some other Java perspectives

Using a recursive Common Table Expression (CTE), you can generate a list of dates, then select from it. Obviously you normally wouldn't want to create three million dates, so this just illustrates the possibilities. You could simply limit the date range inside the CTE and omit the where clause from the select statement using the CTE.

with [dates] as (
    select convert(datetime, '1753-01-01') as [date] --start
    union all
    select dateadd(day, 1, [date])
    from [dates]
    where [date] < '9999-12-31' --end
)
select [date]
from [dates]
where [date] between '2013-01-01' and '2013-12-31'
option (maxrecursion 0)

On Microsoft SQL Server 2005, generating the CTE list of all possible dates took 1:08. Generating one hundred years took less than a second.

In Late September 2016, SciKit Learn 0.18 was released and there was a slight change to the code. With SciKit Learn 0.18 the train_test_split function is now imported from model_selection instead of cross_validation.

from sklearn.cross_validation import train_test_split

has been changed to :

from sklearn.model_selection import train_test_split

The same has also happened for GridSearchCV.

In addition, Win10 gives you an option to open git bash from your working directory by right-clicking on your folder and selecting GitBash here.

You can use simple jQuery jPut plugin

http://plugins.jquery.com/jput/

<script>
$(document).ready(function(){

var json = [{"name": "name1","email":"[email protected]"},{"name": "name2","link":"[email protected]"}];
//while running this code the template will be appended in your div with json data
$("#tbody").jPut({
    jsonData:json,
    //ajax_url:"youfile.json",  if you want to call from a json file
    name:"tbody_template",
});

});
</script>   

<table jput="t_template">
 <tbody jput="tbody_template">
     <tr>
         <td>{{name}}</td>
         <td>{{email}}</td>
     </tr>
 </tbody>
</table>

<table>
 <tbody id="tbody">
 </tbody>
</table>

I found 1 solution. if want to translate this kind of SQL (left join) into Linq Entity...

SQL:

SELECT * FROM [JOBBOOKING] AS [t0]
LEFT OUTER JOIN [REFTABLE] AS [t1] ON ([t0].[trxtype] = [t1].[code])
                                  AND ([t1]. [reftype] = "TRX")

LINQ:

from job in JOBBOOKINGs
join r in (from r1 in REFTABLEs where r1.Reftype=="TRX" select r1) 
          on job.Trxtype equals r.Code into join1
from j in join1.DefaultIfEmpty()
select new
{
   //cols...
}

I also faced this issue. I was having JDK 1.8.0_121. I upgraded JDK to 1.8.0_181 and it worked like a charm.

change your code to:

function ChangePurpose(Vid, PurId) {
    var Success = false;
    $.ajax({
        type: "POST",
        url: "CHService.asmx/SavePurpose",
        dataType: "text",
        async: false,
        data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
        contentType: "application/json; charset=utf-8",
        success: function (data) {
            Success = true;
        },
        error: function (textStatus, errorThrown) {
            Success = false;
        }
    });
    //done after here
    return Success;
} 

You can only return the values from a synchronous function. Otherwise you will have to make a callback.

So I just added async:false, to your ajax call

Update:

jquery ajax calls are asynchronous by default. So success & error functions will be called when the ajax load is complete. But your return statement will be executed just after the ajax call is started.

A better approach will be:

     // callbackfn is the pointer to any function that needs to be called
     function ChangePurpose(Vid, PurId, callbackfn) {
        var Success = false;
        $.ajax({
            type: "POST",
            url: "CHService.asmx/SavePurpose",
            dataType: "text",
            data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
            contentType: "application/json; charset=utf-8",
            success: function (data) {
                callbackfn(data)
            },
            error: function (textStatus, errorThrown) {
                callbackfn("Error getting the data")
            }
        });
     } 

     function Callback(data)
     {
        alert(data);
     }

and call the ajax as:

 // Callback is the callback-function that needs to be called when asynchronous call is complete
 ChangePurpose(Vid, PurId, Callback);

Long ago it was impossible to reliably get the list of processes locking a file because Windows simply did not track that information. To support the Restart Manager API, that information is now tracked.

I put together code that takes the path of a file and returns a List<Process> of all processes that are locking that file.

Using from Limited Permission (e.g. IIS)

This call accesses the registry. If the process does not have permission to do so, you will get ERROR_WRITE_FAULT, meaning An operation was unable to read or write to the registry. You could selectively grant permission to your restricted account to the necessary part of the registry. It is more secure though to have your limited access process set a flag (e.g. in the database or the file system, or by using an interprocess communication mechanism such as queue or named pipe) and have a second process call the Restart Manager API.

Granting other-than-minimal permissions to the IIS user is a security risk.

Yes. You can do:

gdb program_name program_pid

A shortcut would be (assuming only one instance is running):

gdb program_name `pidof program_name`

Maybe you're trying to uninstall an app that is a phone administrator.

To be able to uninstall it, go to Seetings > Security > Phone Administrators. If the app is listed, uncheck it and confirm the operation.

After that, you should be able to uninstall it using the App settings area or adb.

For a system-agnostic solution that works on both Windows and Linux, no matter what the input path, one could use os.path.join(os.sep, rootdir + os.sep, targetdir)

On WIndows:

>>> os.path.join(os.sep, "C:" + os.sep, "Windows")
'C:\\Windows'

On Linux:

>>> os.path.join(os.sep, "usr" + os.sep, "lib")
