The idiomatic way to do this with LINQ is to process the collection and return a new collection mapped in the fashion you want. For example, to add a constant to every element, you'd want something like

var newNumbers = oldNumbers.Select(i => i + 8);

Doing this in a functional way instead of mutating the state of your existing collection frequently helps you separate distinct operations in a way that's both easier to read and easier for the compiler to reason about.

If you're in a situation where you actually want to apply an action to every element of a collection (an action with side effects that are unrelated to the actual contents of the collection) that's not really what LINQ is best suited for, although you could fake it with Select (or write your own IEnumerable extension method, as many people have.) It's probably best to stick with a foreach loop in that case.

I would try to connect to your Sharepoint site with this tool here. If that works you can be sure that the problem is in your code / configuration. That maybe does not solve your problem immediately but it rules out that there is something wrong with the server. Assuming that it does not work I would investigate the following:

• Does your user really have enough rights on the site?
• Is there a proxy that interferes? (Your configuration looks a bit like there is a proxy. Can you bypass it?)

I think there is nothing wrong with using security mode Transport, but I am not so sure about the proxyCredentialType="Ntlm", maybe this should be set to None.

cracked it after 2 hours...

1. download this usb driver: http://dlcdnet.asus.com/pub/ASUS/EeePAD/nexus7/usb_driver_r06_windows.zip

2.go to the device manager , right click the nexus device and choose properties, choose "hardware" and then choose update your driver , choose manualy and pick the folder you opend the zip file to and press apply.

3.open your setting in nexus . go to : "about the device" , at to the bottom of the page and press it strong text7 times .

4.open the developers menu and enable debug with usb.

5.finally press storage from the setting menu and click the menu that apears at the top left corner. press the connect usb to the computer, choose the second option (PTP).

one more thing: if that doesn't work restart your computer

that should do the trick , they couldn't make it more simple than that...

Did you try:

$(this).is(':focus');

Take a look at Using jQuery to test if an input has focus it features some more examples

You could try xmllint

The xmllint program parses one or more XML files, specified on the command line as xmlfile. It prints various types of output, depending upon the options selected. It is useful for detecting errors both in XML code and in the XML parser itse

It allows you select elements in the XML doc by xpath, using the --pattern option.

On Mac OS X (Yosemite), it is installed by default.
On Ubuntu, if it is not already installed, you can run apt-get install libxml2-utils

Perhaps your main function has been commented out because of e.g. preprocessing. To learn what preprocessing is doing, try gcc -C -E es3.c > es3.i then look with an editor into the generated file es3.i (and search main inside it).

First, you should always (since you are a newbie) compile with

  gcc -Wall -g -c es3.c
  gcc -Wall -g es3.o -o es3

The -Wall flag is extremely important, and you should always use it. It tells the compiler to give you (almost) all warnings. And you should always listen to the warnings, i.e. correct your source code file es3.C till you got no more warnings.

The -g flag is important also, because it asks gcc to put debugging information in the object file and the executable. Then you are able to use a debugger (like gdb) to debug your program.

To get the list of symbols in an object file or an executable, you can use nm.

Of course, I'm assuming you use a GNU/Linux system (and I invite you to use GNU/Linux if you don't use it already).

Assuming you are referring to Django's Auth User, in your view:

def game(request):
  user = request.user

  gta = Game.objects.create(name="gta", owner=user)

When you check out a tag, you have what's called a "detached head". Normally, Git's HEAD commit is a pointer to the branch that you currently have checked out. However, if you check out something other than a local branch (a tag or a remote branch, for example) you have a "detached head" -- you're not really on any branch. You should not make any commits while on a detached head.

It's okay to check out a tag if you don't want to make any edits. If you're just examining the contents of files, or you want to build your project from a tag, it's okay to git checkout my_tag and work with the files, as long as you don't make any commits. If you want to start modifying files, you should create a branch based on the tag:

$ git checkout -b my_tag_branch my_tag

will create a new branch called my_tag_branch starting from my_tag. It's safe to commit changes on this branch.

See Converting unix timestamp to excel date-time forum thread.

Some of the files individually listed by Simon would also be found with something like the following command, but with some additional assurance about thoroughness, and without the recklessness of using rm -rf with wildcards:

find ~ \
  -path ~/Library/Caches/Metadata/Safari -prune -o \
  -iname \*android\*studio\* -print -prune

Also don't forget about the SDK, which is now separate from the application, and ~/.gradle/ (see vijay's answer).

SELECT convert(varchar(10), '23/07/2009', 111)

The following solution is specifically for wamp environments:

This foxed me for a little while, tried all the other suggestions, $PATH etc even searched the windows registry looking for clues:

The GUI (wampmanager) indicates I have version 7 selected and yes if I phpinfo() in a page in the browser it will tell me its version 7.x.x yet php -v in the command prompt reports a 5.x.x

If you right click on the wampmanager head to icon->tools->delete unused versions and remove the old version, let it restart the services then the command prompt will return a 7.x.x

This solution means you no longer have the old version if you want to switch between php versions but there is a configuration file in C:\wamp64\wampmanager.conf which appears to specify the version to use with CLI (the parameter is called phpCliVersion). I changed it, restarted the server ... thought I had solved it but no effect perhaps I was a little impatient so I have a feeling there may be some mileage in that.

Hope that helps someone

You could skip all this and just put your data in a table. Then refer to the table and header and it will be completely dynamic. I know this is from 3 years ago but someone may still find this useful.

Example code:

Activesheet.Range("TableName[ColumnName]").Copy

You can also use :

activesheet.listobjects("TableName[ColumnName]").Copy

You can even use this reference system in worksheet formulas as well. Its very dynamic.

Hope this helps!

I came across this question having found requests in Firefox were being blocked with the message:

Reason: CORS request did not succeed

After pulling my hair out I found out that a newly installed Firefox extension, Privacy Badger, was blocking the requests.

If you come to this question after scratching your head, try checking to see what extensions you have installed to see if any of them are blocking requests.

See Reason: CORS request did not succeed on MDN for details.

You can have the program create an .ics (iCal) version of the calendar and then you can import this .ics into whichever calendar program you'd like: Google, Outlook, etc.

I know this post is quite old, so I won't bother inputting any code. But please comment on this if you'd like me to provide an outline of how to do this.

I found the solution to the white bars here:

Set viewport-fit=cover on the viewport <meta> tag, i.e.:

<meta name="viewport" content="initial-scale=1, width=device-width, height=device-height, viewport-fit=cover">

The white bars in UIWebView then disappear:

The solution to remove the black areas (provided by @dpogue in a comment below) is to use LaunchStoryboard images with cordova-plugin-splashscreen to replace the legacy launch images, used by Cordova by default. To do so, add the following to the iOS platform in config.xml:

<platform name="ios">    
    <splash src="res/screen/ios/Default@2x~iphone~anyany.png" />
    <splash src="res/screen/ios/Default@2x~iphone~comany.png" />
    <splash src="res/screen/ios/Default@2x~iphone~comcom.png" />
    <splash src="res/screen/ios/Default@3x~iphone~anyany.png" />
    <splash src="res/screen/ios/Default@3x~iphone~anycom.png" />
    <splash src="res/screen/ios/Default@3x~iphone~comany.png" />
    <splash src="res/screen/ios/Default@2x~ipad~anyany.png" />
    <splash src="res/screen/ios/Default@2x~ipad~comany.png" />   

    <!-- more iOS config... -->
</platform>

Then create the images with the following dimensions in res/screen/ios (remove any existing ones):

Default@2x~iphone~anyany.png - 1334x1334
Default@2x~iphone~comany.png - 750x1334
Default@2x~iphone~comcom.png - 1334x750
Default@3x~iphone~anyany.png - 2208x2208
Default@3x~iphone~anycom.png - 2208x1242
Default@3x~iphone~comany.png - 1242x2208
Default@2x~ipad~anyany.png - 2732x2732
Default@2x~ipad~comany.png - 1278x2732

Once the black bars are removed, there's another thing that's different about the iPhone X to address: The status bar is larger than 20px due to the "notch", which means any content at the far top of your Cordova app will be obscured by it:

Rather than hard-coding a padding in pixels, you can handle this automatically in CSS using the new safe-area-inset-* constants in iOS 11.

Note: in iOS 11.0 the function to handle these constants was called constant() but in iOS 11.2 Apple renamed it to env() (see here), therefore to cover both cases you need to overload the CSS rule with both and rely on the CSS fallback mechanism to apply the appropriate one:

body{
    padding-top: constant(safe-area-inset-top);
    padding-top: env(safe-area-inset-top);
}

The result is then as desired: the app content covers the full screen, but is not obscured by the "notch":

I've created a Cordova test project which illustrates the above steps: webview-test.zip

Notes:

Footer buttons

• If your app has footer buttons (as mine does), you will also need to apply safe-area-inset-bottom to avoid them being overlapped by the virtual Home button on iPhone X.
• In my case, I couldn't apply this to <body> as the footer is absolutely positioned, so I needed to apply it directly to the footer:

.toolbar-footer{
    margin-bottom: constant(safe-area-inset-bottom);
    margin-bottom: env(safe-area-inset-bottom);
}

cordova-plugin-statusbar

• The status bar size has changed on iPhone X, so older versions of cordova-plugin-statusbar display incorrectly on iPhone X
• Mike Hartington has created this pull request which applies the necessary changes.
• This was merged into the [email protected] release, so make sure you're using at least this version to apply to safe-area-insets

splashscreen

• The LaunchScreen storyboard constraints changed on iOS 11/iPhone X, meaning the splashscreen appeared to "jump" on launch when using existing versions of the plugin (see here).
• This was captured in bug report CB-13505, fixed PR cordova-ios#354 and released in [email protected], so make sure you're using a recent version of the cordova-ios platform.

device orientation

• When using UIWebView on iOS 11.0, rotating from portrait > landscape > portrait causes the safe-area-inset not to be re-applied, causing the content to be obscured by the notch again (as highlighted by jms in a comment below).
• Also happens if app is launched in landscape then rotated to portrait
• This doesn't happen when using WKWebView via cordova-plugin-wkwebview-engine.
• Radar report: http://www.openradar.me/radar?id=5035192880201728
• Update: this appears to have been fixed in iOS 11.1

For reference, this is the original Cordova issue I opened which captures this: https://issues.apache.org/jira/browse/CB-13273

Places you can view the console! Just to have them all in one answer.

Firefox

http://getfirebug.com/

(you can also now use Firefox's built in developer tools Ctrl+Shift+J (Tools > Web Developer > Error Console), but Firebug is much better; use Firebug)

Safari and Chrome

Basically the same.

https://developers.google.com/chrome-developer-tools/docs/overview

https://developer.apple.com/technologies/safari/developer-tools.html

Internet Explorer

Don't forget you can use compatibility modes to debug IE7 and IE8 in IE9 or IE10

http://msdn.microsoft.com/en-us/library/ie/gg589507(v=vs.85).aspx

http://msdn.microsoft.com/en-us/library/dd565628(v=vs.85).aspx

If you must access the console in IE6 for IE7 use the Firebug Lite bookmarklet

http://getfirebug.com/firebuglite/ look for stable bookmarklet

http://en.wikipedia.org/wiki/Bookmarklet

Opera

http://www.opera.com/dragonfly/

iOS

Works for all iPhones, iPod touch and iPads.

http://developer.apple.com/library/ios/ipad/#DOCUMENTATION/AppleApplications/Reference/SafariWebContent/DebuggingSafarioniPhoneContent/DebuggingSafarioniPhoneContent.html

Now with iOS 6 you can view the console through Safari in OS X if you plug in your device. Or you can do so with the emulator, simply open a Safari browser window and go to the "Develop" tab. There you will find options to get the Safari inspector to communicate with your device.

Windows Phone, Android

Both of these have no console built in and no bookmarklet ability. So we use http://jsconsole.com/ type :listen and it will give you a script tag to place in your HTML. From then on you can view your console inside the jsconsole website.

iOS and Android

You can also use http://html.adobe.com/edge/inspect/ to access web inspector tools and the console on any device using their convenient browser plugin.

Older browser problems

Lastly older versions of IE will crash if you use console.log in your code and not have the developer tools open at the same time. Luckily it's an easy fix. Use the below code snippet at the top of your code:

 if(!window.console){ window.console = {log: function(){} }; } 

This checks to see if the console is present, and if not it sets it to an object with a blank function called log. This way window.console and window.console.log is never truly undefined.

sprintf: Writes formatted data to a character string in memory instead of stdout

Syntax of sprintf is:

#include <stdio.h>
int sprintf (char *string, const char *format
[,item [,item]…]);

Here,

String refers to the pointer to a buffer in memory where the data is to be written.

Format refers to pointer to a character string defining the format.

Each item is a variable or expression specifying the data to write.

The value returned by sprintf is greater than or equal to zero if the operation is successful or in other words the number of characters written, not counting the terminating null character is returned and returns a value less than zero if an error occurred.

printf: Prints to stdout

Syntax for printf is:

printf format [argument]…

The only difference between sprintf() and printf() is that sprintf() writes data into a character array, while printf() writes data to stdout, the standard output device.

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

public <T> List<T> getIntersectOfCollections(Collection<T> first, Collection<T> second) {
        return first.stream()
                .filter(second::contains)
                .collect(Collectors.toList());
    }

I find the following most elegant:

b = np.insert(a, 3, values=0, axis=1) # Insert values before column 3

An advantage of insert is that it also allows you to insert columns (or rows) at other places inside the array. Also instead of inserting a single value you can easily insert a whole vector, for instance duplicate the last column:

b = np.insert(a, insert_index, values=a[:,2], axis=1)

Which leads to:

array([[1, 2, 3, 3],
       [2, 3, 4, 4]])

For the timing, insert might be slower than JoshAdel's solution:

In [1]: N = 10

In [2]: a = np.random.rand(N,N)

In [3]: %timeit b = np.hstack((a, np.zeros((a.shape[0], 1))))
100000 loops, best of 3: 7.5 µs per loop

In [4]: %timeit b = np.zeros((a.shape[0], a.shape[1]+1)); b[:,:-1] = a
100000 loops, best of 3: 2.17 µs per loop

In [5]: %timeit b = np.insert(a, 3, values=0, axis=1)
100000 loops, best of 3: 10.2 µs per loop

The best modern library for such a task in my opinion is Picasso by Square. It allows to load an image to an ImageView by URL with one-liner:

Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);

I used below function to compare two strings and It is working good.

function CompareUserId (first, second)
{

   var regex = new RegExp('^' + first+ '$', 'i');
   if (regex.test(second)) 
   {
        return true;
   }
   else 
   {
        return false;
   }
   return false;
}

Disclaimer This approach requires two system calls which is more susceptible to race conditions under certain environments/conditions. If you're writing something more sophisticated than a simple throwaway script running in a controlled environment, you're better off going with the accepted answer that requires only one system call.

While inserting multiple rows with a single INSERT statement is generally faster, it leads to a more complicated and often unsafe code. Below I present the best practices when it comes to inserting multiple records in one go using PHP.

To insert multiple new rows into the database at the same time, one needs to follow the following 3 steps:

1. Start transaction (disable autocommit mode)
2. Prepare INSERT statement
3. Execute it multiple times

Using database transactions ensures that the data is saved in one piece and significantly improves performance.

How to properly insert multiple rows using PDO

PDO is the most common choice of database extension in PHP and inserting multiple records with PDO is quite simple.

$pdo = new \PDO("mysql:host=localhost;dbname=test;charset=utf8mb4", 'user', 'password', [
    \PDO::ATTR_ERRMODE => \PDO::ERRMODE_EXCEPTION,
    \PDO::ATTR_EMULATE_PREPARES => false
]);

// Start transaction
$pdo->beginTransaction();

// Prepare statement
$stmt = $pdo->prepare('INSERT 
    INTO `pxlot` (realname,email,address,phone,status,regtime,ip) 
    VALUES (?,?,?,?,?,?,?)');

// Perform execute() inside a loop
// Sample data coming from a fictitious data set, but the data can come from anywhere
foreach ($dataSet as $data) {
    // All seven parameters are passed into the execute() in a form of an array
    $stmt->execute([$data['name'], $data['email'], $data['address'], getPhoneNo($data['name']), '0', $data['regtime'], $data['ip']]);
}

// Commit the data into the database
$pdo->commit();

How to properly insert multiple rows using mysqli

The mysqli extension is a little bit more cumbersome to use but operates on very similar principles. The function names are different and take slightly different parameters.

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new \mysqli('localhost', 'user', 'password', 'database');
$mysqli->set_charset('utf8mb4');

// Start transaction
$mysqli->begin_transaction();

// Prepare statement
$stmt = $mysqli->prepare('INSERT 
    INTO `pxlot` (realname,email,address,phone,status,regtime,ip) 
    VALUES (?,?,?,?,?,?,?)');

// Perform execute() inside a loop
// Sample data coming from a fictitious data set, but the data can come from anywhere
foreach ($dataSet as $data) {
    // mysqli doesn't accept bind in execute yet, so we have to bind the data first
    // The first argument is a list of letters denoting types of parameters. It's best to use 's' for all unless you need a specific type
    // bind_param doesn't accept an array so we need to unpack it first using '...'
    $stmt->bind_param('sssssss', ...[$data['name'], $data['email'], $data['address'], getPhoneNo($data['name']), '0', $data['regtime'], $data['ip']]);
    $stmt->execute();
}

// Commit the data into the database
$mysqli->commit();

Performance

Both extensions offer the ability to use transactions. Executing prepared statement with transactions greatly improves performance, but it's still not as good as a single SQL query. However, the difference is so negligible that for the sake of conciseness and clean code it is perfectly acceptable to execute prepared statements multiple times. If you need a faster option to insert many records into the database at once, then chances are that PHP is not the right tool.

window.onbeforeunload = function ()
{       

    if (isProcess > 0) 
    {
        return true;       
    }   

    else
    { 
        //do something      
    }
}; 

This function show a confirmation dialog box if you close window or refresh page during any process in browser.This function work in all browsers.You have to set isProcess var in your ajax process.

UPDATED query:

select id from t where id < (select max(id) from t);

It'll select all but the last row from the table t.

Forget trying to decipher the example .ts - as others have said it is often incomplete.

Instead just click on the 'pop-out' icon circled here and you'll get a fully working StackBlitz example.

You can quickly confirm the required modules:

Comment out any instances of ReactiveFormsModule, and sure enough you'll get the error:

Template parse errors:
Can't bind to 'formControl' since it isn't a known property of 'input'. 

You have to define void swapCase before the main definition.

You can use __unused to tell the compiler that variable might not be used.

- (void)myMethod:(__unused NSObject *)theObject    
{
    // there will be no warning about `theObject`, because you wrote `__unused`

    __unused int theInt = 0;
    // there will be no warning, but you are still able to use `theInt` in the future
}

Salt and hash your users' passwords. Never save them in plaintext in your database.

If your panel is 'not opaque' (transparent) you wont see your background color.

You should be able to use join, which joins on the index as default. Given your desired result, you must use outer as the join type.

>>> df1.join(df2, how='outer')
            V1  V2
A 1/1/2012  12  15
  2/1/2012  14 NaN
  3/1/2012 NaN  21
B 1/1/2012  15  24
  2/1/2012   8   9
C 1/1/2012  17 NaN
  2/1/2012   9 NaN
D 1/1/2012 NaN   7
  2/1/2012 NaN  16

Signature: _.join(other, on=None, how='left', lsuffix='', rsuffix='', sort=False) Docstring: Join columns with other DataFrame either on index or on a key column. Efficiently Join multiple DataFrame objects by index at once by passing a list.

Note that the Perldebugger can also be invoked from the scripts shebang line, which is how I mostly use the -x flag you refer to, to debug shell scripts.

#! /usr/bin/perl -d

Cast the Boolean to an integer and sum.

SELECT count(*),sum(myCol::int);

You get 6,3.

Here's a trick: wrap it in sh -c!

screen sh -c './some-script 2>&1 | tee mylog.log'

Where 2>&1 redirects stderr to stdout so tee can catch and log error messages.

=INDEX(GoogleFinance("CURRENCY:" & "EUR" & "USD", "price", A2), 2, 2)

where A2 is the cell with a date formatted as date.

Replace "EUR" and "USD" with your currency pair.

Press Ctrl+Alt+Shift+S in android studio or go to File > Project Structure... Select app on left side and select falvors tab on right side on default config change version code , name and etc...

Try this:

 $('.pickupDate').change(function() {
  var date2 = $('.pickupDate').datepicker('getDate', '+1d'); 
  date2.setDate(date2.getDate()+1); 
  $('.dropoffDate').datepicker('setDate', date2);
});

I recently somehow got to the same mindset, inheriting two classes into a class and ended up on this page (even though i know better) and would like to keep reference to the solution i found perfect in this scenario, without enforcing implementation of interfaces

My solution to this problem would be splitting up your data into classes that make sense:

public class PersonAddressSuper
{
    public PersonBase Person { get; set; }
    public PersonAddress Address { get; set; }

    public class PersonBase
    {
        public int ID { get; set; }
        public string Name { get; set; }
    }
    public class PersonAddress
    {
        public string StreetAddress { get; set; }
        public string City { get; set; }
    }
}

Later on in your code, you could use it like this:

Include Both Parts, Base & Address

PersonAddressSuper PersonSuper = new PersonAddressSuper();
PersonSuper.PersonAddress.StreetAddress = "PigBenis Road 16";

Base Only:

PersonAddressSuper.PersonBase PersonBase = new PersonAddressSuper.PersonBase();
PersonBase.Name = "Joe Shmoe";

Address Only:

PersonAddressSuper.PersonAddress PersonAddress = new PersonAddressSuper.PersonAddress();
PersonAddress.StreetAddress = "PigBenis Road 16";

Only nested classes can be static. By doing so you can use the nested class without having an instance of the outer class.

class OuterClass {
    public static class StaticNestedClass {
    }

    public class InnerClass {
    }

    public InnerClass getAnInnerClass() {
        return new InnerClass();
    }

    //This method doesn't work
    public static InnerClass getAnInnerClassStatically() {
        return new InnerClass();
    }
}

class OtherClass {
    //Use of a static nested class:
    private OuterClass.StaticNestedClass staticNestedClass = new OuterClass.StaticNestedClass();

    //Doesn't work
    private OuterClass.InnerClass innerClass = new OuterClass.InnerClass();

    //Use of an inner class:
    private OuterClass outerclass= new OuterClass();
    private OuterClass.InnerClass innerClass2 = outerclass.getAnInnerClass();
    private OuterClass.InnerClass innerClass3 = outerclass.new InnerClass();
}

Batch file to copy folder is easy.

xcopy /Y C:\Source\*.* C:\NewFolder

Save the above as a batch file, and get Windows to run it on start up.

To do the same thing when folder is updated is trickier, you'll need a program that monitors the folder every x time and check for changes. You can write the program in VB/Java/whatever then schedule it to run every 30mins.

The following code works for me:

System.exit(home.EXIT_ON_CLOSE);

In angular 1.4 +, in addition to adding the dependency

angular.module('myApp', ['ngRoute'])

,we also need to reference the separate angular-route.js file

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

From the site i found out the following things:

SQL SERVER – @@IDENTITY vs SCOPE_IDENTITY() vs IDENT_CURRENT – Retrieve Last Inserted Identity of Record March 25, 2007 by pinaldave

SELECT @@IDENTITY It returns the last IDENTITY value produced on a connection, regardless of the table that produced the value, and regardless of the scope of the statement that produced the value. @@IDENTITY will return the last identity value entered into a table in your current session. While @@IDENTITY is limited to the current session, it is not limited to the current scope. If you have a trigger on a table that causes an identity to be created in another table, you will get the identity that was created last, even if it was the trigger that created it.

SELECT SCOPE_IDENTITY() It returns the last IDENTITY value produced on a connection and by a statement in the same scope, regardless of the table that produced the value. SCOPE_IDENTITY(), like @@IDENTITY, will return the last identity value created in the current session, but it will also limit it to your current scope as well. In other words, it will return the last identity value that you explicitly created, rather than any identity that was created by a trigger or a user defined function.

SELECT IDENT_CURRENT(‘tablename’) It returns the last IDENTITY value produced in a table, regardless of the connection that created the value, and regardless of the scope of the statement that produced the value. IDENT_CURRENT is not limited by scope and session; it is limited to a specified table. IDENT_CURRENT returns the identity value generated for a specific table in any session and any scope.

$('#' + theMysteryId + '.someClass').each(function() { /* do stuff */ });

Have tried many things with respect to scroll, but the below code has provided better results.

This will scroll until the element is in view:

WebElement element = driver.findElement(By.id("id_of_element"));
((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView(true);", element);
Thread.sleep(500); 

//do anything you want with the element

Use compareTo()

Return Values

0 if the argument Date is equal to this Date; a value less than 0 if this Date is before the Date argument; and a value greater than 0 if this Date is after the Date argument.

Like

if(date1.compareTo(date2)>0) 

Were you expecting player to be a dict rather than a list?

>>> player=[1,2,3]
>>> player["score"]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list indices must be integers, not str
>>> player={'score':1, 'age': 2, "foo":3}
>>> player['score']
1

This is my answer which solved the same problem. Fragment2.java is the fragment class which holds the layout of fragment2.xml.

public void onClick(View v) {
                    Fragment  fragment2 = new Fragement2();
                    FragmentManager fragmentManager = getFragmentManager();
                    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                    fragmentTransaction.replace(R.id.frame_container, fragment2);
                    fragmentTransaction.addToBackStack(null);
                    fragmentTransaction.commit();   
                }

You might find this article (What is SOA? - SOA and Web Services Explained ) helpful.

A little teaser:

• SOA is a style of architecting applications in such a way that they are composed of discrete software agents that have simple, well defined interfaces and are orchestrated through a loose coupling to perform a required function.

• There are 2 roles in SOA- a service provider and a service consumer. A software agent may play both roles. SOA is not an entirely new concept – however, this article mainly focuses on SOA as implemented with web services.

Create a "module" object and declare variables in there. Unlike class-objects that have to be instantiated each time, the module objects are always available. Therefore, a public variable, function, or property in a "module" will be available to all the other objects in the VBA project, macro, Excel formula, or even within a MS Access JET-SQL query def.

Although cursors usually considered horrible evil I believe this is a case for FAST_FORWARD cursor - the closest thing you can get to FOREACH in TSQL.

There are many differences as specified above. Apart from above all, there is one more difference. Response.Redirect() can be used to redirect user to any page which is not part of the application but Server.Transfer() can only be used to redirect user within the application.

//This will work.
Response.Redirect("http://www.google.com");

//This will not work.
Server.Transfer("http://www.google.com");

This function is re-usable:

function usortarr(&$array, $key, $callback = 'strnatcasecmp') {
    uasort($array, function($a, $b) use($key, $callback) {
        return call_user_func($callback, $a[$key], $b[$key]);
    });
}

It works well on string values by default, but you'll have to sub the callback for a number comparison function if all your values are numbers.

It can also be used as below:

from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)

If you know your format is PDF, then I don't see how the HTML tag can be useful... It definitely does not seem to work for me. The other pure LaTeX solutions obviously work just fine. But the whole point of Markdown is not to do LaTeX but to allow for multiple format compilation I believe, including HTML.

Therefore, with this in mind, what works for me is a variation of Nicolas Hamilton's answer to Color Text Stackoverflow question:

#############
## CENTER TXT
ctrFmt = function(x){
  if(out_type == 'latex' || out_type == 'beamer')
    paste0("\\begin{center}\n", x, "\n\\end{center}")
  else if(out_type == 'html')
    paste0("<center>\n", x, "\n</center>")
  else
    x
}

I put this inside my initial setup chunk. Then I use it very easily in my .rmd file:

`r ctrFmt("Centered text in html and pdf!")`

If it is an auto generated key, then you can use Statement#getGeneratedKeys() for this. You need to call it on the same Statement as the one being used for the INSERT. You first need to create the statement using Statement.RETURN_GENERATED_KEYS to notify the JDBC driver to return the keys.

Here's a basic example:

public void create(User user) throws SQLException {
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL_INSERT,
                                      Statement.RETURN_GENERATED_KEYS);
    ) {
        statement.setString(1, user.getName());
        statement.setString(2, user.getPassword());
        statement.setString(3, user.getEmail());
        // ...

        int affectedRows = statement.executeUpdate();

        if (affectedRows == 0) {
            throw new SQLException("Creating user failed, no rows affected.");
        }

        try (ResultSet generatedKeys = statement.getGeneratedKeys()) {
            if (generatedKeys.next()) {
                user.setId(generatedKeys.getLong(1));
            }
            else {
                throw new SQLException("Creating user failed, no ID obtained.");
            }
        }
    }
}

Note that you're dependent on the JDBC driver as to whether it works. Currently, most of the last versions will work, but if I am correct, Oracle JDBC driver is still somewhat troublesome with this. MySQL and DB2 already supported it for ages. PostgreSQL started to support it not long ago. I can't comment about MSSQL as I've never used it.

For Oracle, you can invoke a CallableStatement with a RETURNING clause or a SELECT CURRVAL(sequencename) (or whatever DB-specific syntax to do so) directly after the INSERT in the same transaction to obtain the last generated key. See also this answer.

You can directly export the query result with export option in the result grig. This export has various options to export. I think this will work.

I looked all the ones above. Ended up writing myself. You do not need momentjs for this. A native for loop is enough and makes most sense because a for loop exists to count values in a range.

One Liner:

var getDaysArray = function(s,e) {for(var a=[],d=new Date(s);d<=e;d.setDate(d.getDate()+1)){ a.push(new Date(d));}return a;};

Long Version

var getDaysArray = function(start, end) {
    for(var arr=[],dt=new Date(start); dt<=end; dt.setDate(dt.getDate()+1)){
        arr.push(new Date(dt));
    }
    return arr;
};

List dates in between:

var daylist = getDaysArray(new Date("2018-05-01"),new Date("2018-07-01"));
daylist.map((v)=>v.toISOString().slice(0,10)).join("")
/*
Output: 
    "2018-05-01
    2018-05-02
    2018-05-03
    ...
    2018-06-30
    2018-07-01"
*/

Days from a past date until now:

var daylist = getDaysArray(new Date("2018-05-01"),new Date());
daylist.map((v)=>v.toISOString().slice(0,10)).join("")

------SOLVED------

in this case you want to check two type of count for two cace

case 1:

if result contain only one record other word select single row from database using ->first()

 if(count($result)){
     
       ...record is exist true...
  }

case 2:

if result contain set of multiple row other word using ->get() or ->all()

  if($result->count()) {
    
         ...record is exist true...
  }

Here is a very simple example for MouseOver and MouseOut:

<div id="app">
   <div :style = "styleobj" @mouseover = "changebgcolor" @mouseout = "originalcolor"> 
   </div>
</div>

new Vue({
  el:"#app",
  data:{
     styleobj : {
       width:"100px",
       height:"100px",
       backgroundColor:"red"
     }
  },
  methods:{
    changebgcolor : function() {
      this.styleobj.backgroundColor = "green";
    },
    originalcolor : function() {
      this.styleobj.backgroundColor = "red";
    }
  }
});

The main concern is whether a variable inside the anonymous class instance can be resolved at run-time. It is not a must to make a variable final as long as it is guaranteed that the variable is inside the run-time scope. For example, please see the two variables _statusMessage and _statusTextView inside updateStatus() method.

public class WorkerService extends Service {

Worker _worker;
ExecutorService _executorService;
ScheduledExecutorService _scheduledStopService;

TextView _statusTextView;


@Override
public void onCreate() {
    _worker = new Worker(this);
    _worker.monitorGpsInBackground();

    // To get a thread pool service containing merely one thread
    _executorService = Executors.newSingleThreadExecutor();

    // schedule something to run in the future
    _scheduledStopService = Executors.newSingleThreadScheduledExecutor();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    ServiceRunnable runnable = new ServiceRunnable(this, startId);
    _executorService.execute(runnable);

    // the return value tells what the OS should
    // do if this service is killed for resource reasons
    // 1. START_STICKY: the OS restarts the service when resources become
    // available by passing a null intent to onStartCommand
    // 2. START_REDELIVER_INTENT: the OS restarts the service when resources
    // become available by passing the last intent that was passed to the
    // service before it was killed to onStartCommand
    // 3. START_NOT_STICKY: just wait for next call to startService, no
    // auto-restart
    return Service.START_NOT_STICKY;
}

@Override
public void onDestroy() {
    _worker.stopGpsMonitoring();
}

@Override
public IBinder onBind(Intent intent) {
    return null;
}

class ServiceRunnable implements Runnable {

    WorkerService _theService;
    int _startId;
    String _statusMessage;

    public ServiceRunnable(WorkerService theService, int startId) {
        _theService = theService;
        _startId = startId;
    }

    @Override
    public void run() {

        _statusTextView = MyActivity.getActivityStatusView();

        // get most recently available location as a latitude /
        // longtitude
        Location location = _worker.getLocation();
        updateStatus("Starting");

        // convert lat/lng to a human-readable address
        String address = _worker.reverseGeocode(location);
        updateStatus("Reverse geocoding");

        // Write the location and address out to a file
        _worker.save(location, address, "ResponsiveUx.out");
        updateStatus("Done");

        DelayedStopRequest stopRequest = new DelayedStopRequest(_theService, _startId);

        // schedule a stopRequest after 10 seconds
        _theService._scheduledStopService.schedule(stopRequest, 10, TimeUnit.SECONDS);
    }

    void updateStatus(String message) {
        _statusMessage = message;

        if (_statusTextView != null) {
            _statusTextView.post(new Runnable() {

                @Override
                public void run() {
                    _statusTextView.setText(_statusMessage);

                }

            });
        }
    }

}

Fuzzy Wuzzy is a package that implements Levenshtein distance in python, with some helper functions to help in certain situations where you may want two distinct strings to be considered identical. For example:

>>> fuzz.ratio("fuzzy wuzzy was a bear", "wuzzy fuzzy was a bear")
    91
>>> fuzz.token_sort_ratio("fuzzy wuzzy was a bear", "wuzzy fuzzy was a bear")
    100

and ensure the /usr/local/bin is before /usr/bin in PATH.

i.e.

[bash:~] $ echo $PATH
/usr/local/bin:/usr/bin:/bin

Ensure this always is the case by adding

export PATH=/usr/local/bin:$PATH

to the end of your ~/.bashrc file. Prefixing the PATH environment variable with custom bin folder such as /usr/local/bin or /opt/<some install>/bin is generally recommended to ensure that customizations are found before the default system ones.

This is perhaps a bit late, but may help someone. I come across similar issue with Iterable in my codebase and solution was to use for each without explicitly calling values.iterator();.

int size = 0;
for(T value : values) {
   size++;
}

You may use combination of TimerDispatcher (WPF Timer analog) and Windows "Hooks" to catch cursor position from operational system.

    [DllImport("user32.dll")]
    [return: MarshalAs(UnmanagedType.Bool)]
    public static extern bool GetCursorPos(out POINT pPoint);

Point is a light struct. It contains only X, Y fields.

    public MainWindow()
    {
        InitializeComponent();

        DispatcherTimer dt = new System.Windows.Threading.DispatcherTimer();
        dt.Tick += new EventHandler(timer_tick);
        dt.Interval = new TimeSpan(0,0,0,0, 50);
        dt.Start();
    }

    private void timer_tick(object sender, EventArgs e)
    {
        POINT pnt;
        GetCursorPos(out pnt);
        current_x_box.Text = (pnt.X).ToString();
        current_y_box.Text = (pnt.Y).ToString();
    }

    public struct POINT
    {
        public int X;
        public int Y;

        public POINT(int x, int y)
        {
            this.X = x;
            this.Y = y;
        }
    }

This solution is also resolving the problem with too often or too infrequent parameter reading so you can adjust it by yourself. But remember about WPF method overload with one arg which is representing ticks not milliseconds.

TimeSpan(50); //ticks

My error is caused by a System.import('xxx.js') statment. After replacing it with import xxx from 'xxx.js', the error solved.

I think it is because require('xxx.scss') also caused a dynamic import.

For the case in the question description, in my opinion, dynamic imports is not necessary, so the problem should be solved by just replacing all requires with import ... from ....

For some case which dynamic imports are necessary, you may need @babel/plugin-syntax-dynamic-import as other answers in this question.

As suggested you can change the pivot table content and paste as values. But if you want to change the values dynamically the easiest way I found is Go To Insert->create pivot table Now in the dialog box in the input data field select the cells of your previous pivot table.

This is my take on it:

public enum LoginState { 
    LOGGED_IN(1), LOGGED_OUT(0), IN_TRANSACTION(-1);

    private int code;

    LoginState(int code) {
        this.code = code;
    }

    public int getCode() {
        return code;
    }

    public static LoginState getLoginStateFromCode(int code){
        for(LoginState e : LoginState.values()){
            if(code == e.code) return e;
        }
        return LoginState.LOGGED_OUT; //or null
    }
};

And I have used it with System Preferences in Android like so:

LoginState getLoginState(int i) {
    return LoginState.getLoginStateFromCode(
                prefs().getInt(SPK_IS_LOGIN, LoginState.LOGGED_OUT.getCode())
            );
}

public static void setLoginState(LoginState newLoginState) {
    editor().putInt(SPK_IS_LOGIN, newLoginState.getCode());
    editor().commit();
}

where pref and editor are SharedPreferences and a SharedPreferences.Editor

I had the same problem: I love the resolve object, but that only works for the content of ng-view. What if you have controllers (for top-level nav, let's say) that exist outside of ng-view and which need to be initialized with data before the routing even begins to happen? How do we avoid mucking around on the server-side just to make that work?

Use manual bootstrap and an angular constant. A naiive XHR gets you your data, and you bootstrap angular in its callback, which deals with your async issues. In the example below, you don't even need to create a global variable. The returned data exists only in angular scope as an injectable, and isn't even present inside of controllers, services, etc. unless you inject it. (Much as you would inject the output of your resolve object into the controller for a routed view.) If you prefer to thereafter interact with that data as a service, you can create a service, inject the data, and nobody will ever be the wiser.

Example:

//First, we have to create the angular module, because all the other JS files are going to load while we're getting data and bootstrapping, and they need to be able to attach to it.
var MyApp = angular.module('MyApp', ['dependency1', 'dependency2']);

// Use angular's version of document.ready() just to make extra-sure DOM is fully 
// loaded before you bootstrap. This is probably optional, given that the async 
// data call will probably take significantly longer than DOM load. YMMV.
// Has the added virtue of keeping your XHR junk out of global scope. 
angular.element(document).ready(function() {

    //first, we create the callback that will fire after the data is down
    function xhrCallback() {
        var myData = this.responseText; // the XHR output

        // here's where we attach a constant containing the API data to our app 
        // module. Don't forget to parse JSON, which `$http` normally does for you.
        MyApp.constant('NavData', JSON.parse(myData));

        // now, perform any other final configuration of your angular module.
        MyApp.config(['$routeProvider', function ($routeProvider) {
            $routeProvider
              .when('/someroute', {configs})
              .otherwise({redirectTo: '/someroute'});
          }]);

        // And last, bootstrap the app. Be sure to remove `ng-app` from your index.html.
        angular.bootstrap(document, ['NYSP']);
    };

    //here, the basic mechanics of the XHR, which you can customize.
    var oReq = new XMLHttpRequest();
    oReq.onload = xhrCallback;
    oReq.open("get", "/api/overview", true); // your specific API URL
    oReq.send();
})

Now, your NavData constant exists. Go ahead and inject it into a controller or service:

angular.module('MyApp')
    .controller('NavCtrl', ['NavData', function (NavData) {
        $scope.localObject = NavData; //now it's addressable in your templates 
}]);

Of course, using a bare XHR object strips away a number of the niceties that $http or JQuery would take care of for you, but this example works with no special dependencies, at least for a simple get. If you want a little more power for your request, load up an external library to help you out. But I don't think it's possible to access angular's $http or other tools in this context.

If you need to store a password in memory and would like to have it encrypted you should use SecureString:

http://msdn.microsoft.com/en-us/library/system.security.securestring.aspx

For more general uses I would use a FIPS approved algorithm such as Advanced Encryption Standard, formerly known as Rijndael. See this page for an implementation example:

http://msdn.microsoft.com/en-us/library/system.security.cryptography.rijndael.aspx

There are two important concepts in multithreading environment:

1. atomicity
2. visibility

The volatile keyword eradicates visibility problems, but it does not deal with atomicity. volatile will prevent the compiler from reordering instructions which involve a write and a subsequent read of a volatile variable; e.g. k++. Here, k++ is not a single machine instruction, but three:

1. copy the value to a register;
2. increment the value;
3. place it back.

So, even if you declare a variable as volatile, this will not make this operation atomic; this means another thread can see a intermediate result which is a stale or unwanted value for the other thread.

On the other hand, AtomicInteger, AtomicReference are based on the Compare and swap instruction. CAS has three operands: a memory location V on which to operate, the expected old value A, and the new value B. CAS atomically updates V to the new value B, but only if the value in V matches the expected old value A; otherwise, it does nothing. In either case, it returns the value currently in V. The compareAndSet() methods of AtomicInteger and AtomicReference take advantage of this functionality, if it is supported by the underlying processor; if it is not, then the JVM implements it via spin lock.

just surprised that nobody talk about pg_hba file as it can be a good reason to get this error code.

Check here for those who forgot to configure it: http://www.postgresql.org/docs/current/static/auth-pg-hba-conf.html

You can Intersect the two lists:

if (A.Intersect(B).Any())

$provide service

They are technically the same thing, it's actually a different notation of using the provider function of the $provide service.

• If you're using a class: you could use the service notation.
• If you're using an object: you could use the factory notation.

The only difference between the service and the factory notation is that the service is new-ed and the factory is not. But for everything else they both look, smell and behave the same. Again, it's just a shorthand for the $provide.provider function.

// Factory

angular.module('myApp').factory('myFactory', function() {

  var _myPrivateValue = 123;

  return {
    privateValue: function() { return _myPrivateValue; }
  };

});

// Service

function MyService() {
  this._myPrivateValue = 123;
}

MyService.prototype.privateValue = function() {
  return this._myPrivateValue;
};

angular.module('myApp').service('MyService', MyService);

You can try this.

You can use textwrap module to break it in multiple lines

import textwrap
str="ABCDEFGHIJKLIMNO"
print("\n".join(textwrap.wrap(str,8)))

ABCDEFGH
IJKLIMNO

From the documentation:

textwrap.wrap(text[, width[, ...]])
Wraps the single paragraph in text (a string) so every line is at most width characters long. Returns a list of output lines, without final newlines.

Optional keyword arguments correspond to the instance attributes of TextWrapper, documented below. width defaults to 70.

See the TextWrapper.wrap() method for additional details on how wrap() behaves.

Try:

SELECT A.id FROM
(
  SELECT table1.id FROM table1 
  LEFT JOIN table2 ON table1.id = table2.user_one
  WHERE table2.user_one IS NULL
) A
JOIN (
  SELECT table1.id FROM table1 
  LEFT JOIN table2 ON table1.id = table2.user_two
  WHERE table2.user_two IS NULL
) B
ON A.id = B.id

See Demo

Or you could use two LEFT JOINS with aliases like:

SELECT table1.id FROM table1 
 LEFT JOIN table2 A ON table1.id = A.user_one
 LEFT JOIN table2 B ON table1.id = B.user_two
 WHERE A.user_one IS NULL
 AND B.user_two IS NULL

See 2nd Demo

I thought of

 SELECT LENGTH('123-345-566') - LENGTH(REPLACE('123-345-566', '-', '')) FROM DUAL;

http://msdn.microsoft.com/en-us/library/system.type.gettype.aspx

Console.WriteLine("typeField is a {0}", typeField.GetType());

which would give you something like

typeField is a String

typeField is a DateTime

or

http://msdn.microsoft.com/en-us/library/58918ffs(v=vs.71).aspx

its work short code

$('.SeeMore2').click(function(){ var $this = $(this).toggleClass('SeeMore2'); if($(this).hasClass('SeeMore2')) { $(this).text('See More');
} else { $(this).text('See Less'); } });

Sometimes if it is a new server you need to configure or install ASP.NET feature on IIS for it to be able to read your web.config file.

In my case this was the reason.

Maybe this will help someone. I was using a nested app. project.appname and I actually had project and project.appname in INSTALLED_APPS. Removing project from INSTALLED_APPS allowed the changes to be detected.

You could have the batch file change the current working directory (CD).

Interesting, I didn't have any references to stdole in my project, but I had a user still receiving the error. I had to add the reference, then change the setting to include. Hopefully that will work.

EDIT 2015 May

Disclaimer: I've taken the snippet from the answer linked below:

Important Update!

In addition to WebKit, as of Firefox 35 we'll be able to use the appearance property:

Using -moz-appearance with the none value on a combobox now remove the dropdown button

So now in order to hide the default styling, it's as easy as adding the following rules on our select element:

select {
   -webkit-appearance: none;
   -moz-appearance: none;
   appearance: none;
}

For IE 11 support, you can use [::-ms-expand][15].

select::-ms-expand { /* for IE 11 */
    display: none;
}

Old Answer

Unfortunately what you ask is not possible by using pure CSS. However, here is something similar that you can choose as a work around. Check the live code below.

div { _x000D_
  margin: 10px;_x000D_
  padding: 10px; _x000D_
  border: 2px solid purple; _x000D_
  width: 200px;_x000D_
  -webkit-border-radius: 5px;_x000D_
  -moz-border-radius: 5px;_x000D_
  border-radius: 5px;_x000D_
}_x000D_
div > ul { display: none; }_x000D_
div:hover > ul {display: block; background: #f9f9f9; border-top: 1px solid purple;}_x000D_
div:hover > ul > li { padding: 5px; border-bottom: 1px solid #4f4f4f;}_x000D_
div:hover > ul > li:hover { background: white;}_x000D_
div:hover > ul > li:hover > a { color: red; }

<div>_x000D_
  Select_x000D_
  <ul>_x000D_
    <li><a href="#">Item 1</a></li>_x000D_
    <li><a href="#">Item 2</a></li>_x000D_
    <li><a href="#">Item 3</a></li>_x000D_
  </ul>_x000D_
</div>

EDIT

Here is the question that you asked some time ago. How to style a <select> dropdown with CSS only without JavaScript? As it tells there, only in Chrome and to some extent in Firefox you can achieve what you want. Otherwise, unfortunately, there is no cross browser pure CSS solution for styling a select.

Late answer, but I found out that this is the simplest solution (if you don't use jQuery):

var myClasses = document.querySelectorAll('.my-class'),
    i = 0,
    l = myClasses.length;

for (i; i < l; i++) {
    myClasses[i].style.display = 'none';
}

Demo

In case you want to split by spaces, you can just use .split():

a = 'mary had a little lamb'
z = a.split()
print z

Output:

['mary', 'had', 'a', 'little', 'lamb'] 

Using dplyr:

require(dplyr)    
df <- data.frame(A = c(1, 1, 2, 3, 3), B = c(2, 3, 3, 5, 6))
df %>% group_by(A) %>% summarise(B = sum(B))

## Source: local data frame [3 x 2]
## 
##   A  B
## 1 1  5
## 2 2  3
## 3 3 11

With sqldf:

library(sqldf)
sqldf('SELECT A, SUM(B) AS B FROM df GROUP BY A')

After trying different things. This worked.

Delete your node modules folder and run

npm i

If you don't want use external package , Just add the following function in your utilities :

var params=function(req){
  let q=req.url.split('?'),result={};
  if(q.length>=2){
      q[1].split('&').forEach((item)=>{
           try {
             result[item.split('=')[0]]=item.split('=')[1];
           } catch (e) {
             result[item.split('=')[0]]='';
           }
      })
  }
  return result;
}

Then , in createServer call back , add attribute params to request object :

 http.createServer(function(req,res){
     req.params=params(req); // call the function above ;
      /**
       * http://mysite/add?name=Ahmed
       */
     console.log(req.params.name) ; // display : "Ahmed"

})

Polymorphism: Polymorphism is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object.

Dynamic Binding/Runtime Polymorphism :

Run time Polymorphism also known as method overriding. In this Mechanism by which a call to an overridden function is resolved at a Run-Time.

public class DynamicBindingTest {

    public static void main(String args[]) {
        Vehicle vehicle = new Car(); //here Type is vehicle but object will be Car
        vehicle.start();       //Car's start called because start() is overridden method
    }
}

class Vehicle {

    public void start() {
        System.out.println("Inside start method of Vehicle");
    }
}

class Car extends Vehicle {

    @Override
    public void start() {
        System.out.println("Inside start method of Car");
    }
}

Output:

Inside start method of Car

Static Binding /compile-time polymorphism:

Which method is to be called is decided at compile-time only.

public class StaticBindingTest {

    public static void main(String args[])  {
       Collection c = new HashSet();
       StaticBindingTest et = new StaticBindingTest();
       et.sort(c);

    }

    //overloaded method takes Collection argument
    public Collection sort(Collection c){
        System.out.println("Inside Collection sort method");
        return c;
    }


   //another overloaded method which takes HashSet argument which is sub class
    public Collection sort(HashSet hs){
        System.out.println("Inside HashSet sort method");
        return hs;
    }

}

Output: Inside Collection sort metho

np.count_nonzero(~np.isnan(data))

~ inverts the boolean matrix returned from np.isnan.

np.count_nonzero counts values that is not 0\false. .sum should give the same result. But maybe more clearly to use count_nonzero

Testing speed:

In [23]: data = np.random.random((10000,10000))

In [24]: data[[np.random.random_integers(0,10000, 100)],:][:, [np.random.random_integers(0,99, 100)]] = np.nan

In [25]: %timeit data.size - np.count_nonzero(np.isnan(data))
1 loops, best of 3: 309 ms per loop

In [26]: %timeit np.count_nonzero(~np.isnan(data))
1 loops, best of 3: 345 ms per loop

In [27]: %timeit data.size - np.isnan(data).sum()
1 loops, best of 3: 339 ms per loop

data.size - np.count_nonzero(np.isnan(data)) seems to barely be the fastest here. other data might give different relative speed results.

I want to add some to the given answers.

In case you encounter (or want to use) a ternary in a situation like 'display a variable if it's set, else...', you can make it even shorter, without a ternary.

Instead of:

var welcomeMessage  = 'Hello ' + (username ? username : 'guest');

You can use:

var welcomeMessage  = 'Hello ' + (username || 'guest');

This is Javascripts equivallent of PHP's shorthand ternary operator ?:

Or even:

var welcomeMessage  = 'Hello ' + (username || something || maybethis || 'guest');

It evaluates the variable, and if it's false or unset, it goes on to the next.

Comments work fine in any of the usual Java/Groovy forms, but you can't currently use groovydoc to process your Jenkinsfile (s).

First, groovydoc chokes on files without extensions with the wonderful error

... and second, as far as I can tell Javadoc-style commments at the start of a groovy script are ignored. So even if you copy/rename your Jenkinsfile to Jenkinsfile.groovy, you won't get much useful output.

I want to be able to use a

comment at the start of my Jenkinsfile. No such luck (yet).

groovydoc will process classes and methods defined in your Jenkinsfile if you pass -private to the command, though.

I’ve just solved the same problem. I had MinGW with GCC and G++ installed but not make. This command helped me:

mingw-get.exe install mingw32-make

After running it, clear CMake cache (delete the CMakeCache.txt file in the CMake's working directory) and run CMake again.

NumPy has a numpy.mean which is an arithmetic mean. Usage is as simple as this:

>>> import numpy
>>> a = [1, 2, 4]
>>> numpy.mean(a)
2.3333333333333335

It means you're in "record macro" mode. This mode is entered by typing q followed by a register name, and can be exited by typing q again.

The problem with your conditional is in this part sshkey_result.rc == 1, because sshkey_result does not contain rc attribute and entire conditional fails.

If you want to check if file exists check exists attribute.

Here you can read more about stat module and how to use it.

for jqLite just use triggerHandler with event name, To simulate a "click" try:

angular.element("tr").triggerHandler("click");

Here's the list of jQLite commands

I used following code.where imageCoverView is UIView holds UIImageView

if (image.size.height<self.imageCoverView.bounds.size.height && image.size.width<self.imageCoverView.bounds.size.width)
{
    [self.profileImageView sizeToFit];
    self.profileImageView.contentMode =UIViewContentModeCenter
}
else
{
    self.profileImageView.contentMode =UIViewContentModeScaleAspectFit;
}

1. first delete the file (project).
2. then rm -rf \Users\Indrajith.E\AppData\Roaming\npm-cache_logs\2019-08-22T08_41_00_271Z-debug.log (this is the file(log) which is showing error).
3. recreate your project for example :- npx create-react-app hello_world
4. then cd hello_world.
5. then npm start.

I was also having this same error but hopefully after spending 1 day on this error i have got this solution and it got started perfectly and i also hope this works for you guys also...

ngClick directive (as well as all other event directives) creates $event variable which is available on same scope. This variable is a reference to JS event object and can be used to call stopPropagation():

<table>
  <tr ng-repeat="user in users" ng-click="showUser(user)">
    <td>{{user.firstname}}</td>
    <td>{{user.lastname}}</td>
    <td>
      <button class="btn" ng-click="deleteUser(user.id, $index); $event.stopPropagation();">
        Delete
      </button>
    </td>              
  </tr>

The Git support done by Microsoft in Visual Studio is just good enough for basic work (commit/fetch/merge and push). My advice is just to avoid it...

I highly prefer GitExtensions (or in less proportion SourceTree). Because seeing the DAG is for me really important to understand how Git works. And you are a lot more aware of what the other contributors to your project have done!

In Visual Studio, you can't quickly see the diff between files or commit, nor (add to the index) and commit only part of modifications. Browse your history is not good either... All that ending in a painful experience!

And, for example, GitExtensions is bundled with interesting plugins: background fetch, GitFlow,... and now, continuous integration!

For the users of Visual Studio 2015, Git is taking shape if you install the GitHub extension. But an external tool is still better ;-)

I had a directory of files that I wanted to check. I created an Excel macro to determine ANSI vs. UTF-8. This worked for me.

You can also create custom states and update it's value duting task execution. This example is from docs:

@app.task(bind=True)
def upload_files(self, filenames):
    for i, file in enumerate(filenames):
        if not self.request.called_directly:
            self.update_state(state='PROGRESS',
                meta={'current': i, 'total': len(filenames)})

The use of CultureInfo class worked for me, I hope help you.

    string value = "1200.00";

    decimal result = Convert.ToDecimal(value, culture);

Define two dates using new Date(). Calculate the time difference of two dates using date2. getTime() – date1. getTime(); Calculate the no. of days between two dates, divide the time difference of both the dates by no. of milliseconds in a day (10006060*24)

You need to understand the difference between classes and objects. From the Java tutorial:

An object is a software bundle of related state and behavior

A class is a blueprint or prototype from which objects are created

You've defined the prototypes but done nothing with them. To use an object, you need to create it. In Java, we use the new keyword.

new Date();

You will need to assign the object to a variable of the same type as the class the object was created from.

Date d = new Date();

Once you have a reference to the object you can interact with it

d.date("01", "12", "14");

The exception to this is static methods that belong to the class and are referenced through it

public class MyDate{
  public static date(){ ... }
}

...
MyDate.date();

In case you aren't aware, Java already has a class for representing dates, you probably don't want to create your own.

You can achieve this with the background-size property, which is now supported by most browsers.

To scale the background image to fit inside the div:

background-size: contain;

To scale the background image to cover the whole div:

background-size: cover;

There also exists a filter for IE 5.5+ support, as well as vendor prefixes for some older browsers.

The problem is that the META-INF folder won't get filtered so multiple entries of NOTICE or LICENSE cause duplicates when building and it is tryed to copy them together.

Dirty Quick Fix:

Open the .jar file in your .gradle/caches/... folder (with a zip compatible tool) and remove or rename the files in the META-INF folder that cause the error (usally NOTICE or LICENSE). (I know thats also in the OP, but for me it was not really clear until I read the google forum)

EDIT:

This was fixed in 0.7.1. Just add the confilcting files to exclude.

android {
    packagingOptions {
        exclude 'META-INF/LICENSE'
    }
}

Generator is a function that produces an iterator. Therefore, once you have iterator instance, use next() to fetch the next item from the iterator. As an example, use next() function to fetch the first item, and later use for in to process remaining items:

# create new instance of iterator by calling a generator function
items = generator_function()

# fetch and print first item
first = next(items)
print('first item:', first)

# process remaining items:
for item in items:
    print('next item:', item)

The process for timing out an operations is described in the documentation for signal.

The basic idea is to use signal handlers to set an alarm for some time interval and raise an exception once that timer expires.

Note that this will only work on UNIX.

Here's an implementation that creates a decorator (save the following code as timeout.py).

from functools import wraps
import errno
import os
import signal

class TimeoutError(Exception):
    pass

def timeout(seconds=10, error_message=os.strerror(errno.ETIME)):
    def decorator(func):
        def _handle_timeout(signum, frame):
            raise TimeoutError(error_message)

        def wrapper(*args, **kwargs):
            signal.signal(signal.SIGALRM, _handle_timeout)
            signal.alarm(seconds)
            try:
                result = func(*args, **kwargs)
            finally:
                signal.alarm(0)
            return result

        return wraps(func)(wrapper)

    return decorator

This creates a decorator called @timeout that can be applied to any long running functions.

So, in your application code, you can use the decorator like so:

from timeout import timeout

# Timeout a long running function with the default expiry of 10 seconds.
@timeout
def long_running_function1():
    ...

# Timeout after 5 seconds
@timeout(5)
def long_running_function2():
    ...

# Timeout after 30 seconds, with the error "Connection timed out"
@timeout(30, os.strerror(errno.ETIMEDOUT))
def long_running_function3():
    ...

You might also try

Application.CalculateFull

or

Application.CalculateFullRebuild

if you don't mind rebuilding all open workbooks, rather than just the active worksheet. (CalculateFullRebuild rebuilds dependencies as well.)

Bluetooth devices can operate in both classic and LE mode at the same time. Sometimes they use a different MAC address depending on which way you are connecting. Calling socket.connect() is using Bluetooth Classic, so you have to make sure the device you got when you scanned was really a classic device.

It's easy to filter for only Classic devices, however:

if(BluetoothDevice.DEVICE_TYPE_LE == device.getType()){ //socket.connect() }

Without this check, it's a race condition as to whether a hybrid scan will give you the Classic device or the BLE device first. It may appear as intermittent inability to connect, or as certain devices being able to connect reliably while others seemingly never can.

If you not positive on where the parent is, this will get you the path;

var path = require('path'),
    __parentDir = path.dirname(module.parent.filename);

fs.readFile(__parentDir + '/foo.bar');

I use json to record anything for a project, I use three tables in fact ! one for the data in json, one for the index of each metadata of the json structure (each meta is encoded by an unique id), and one for the session user, that's all. The benchmark cannot be quantified at this early state of code, but for exemple I was user views (inner join with index) to get a category (or anything, as user, ...), and it was very slow (very very slow, used view in mysql is not the good way). The search module, in this structure, can do anything I want, but, I think mongodb will be more efficient in this concept of full json data record. For my exemple, I user views to create tree of category, and breadcrumb, my god ! so many query to do ! apache itself gone ! and, in fact, for this little website, I use know a php who generate tree and breadcrumb, the extraction of the datas is done by the search module (who use only index), the data table is used only for update. If I want, I can destroy the all indexes, and regenerate it with each data, and do the reverse work to, like, destroy all the data (json) and regenerate it only with the index table. My project is young, running under php and mysql, but, sometime I thing using node js and mongodb will be more efficient for this project.

Use json if you think you can do, just for do it, because you can ! and, forget it if it was a mistake; try by make good or bad choice, but try !

You are looking for System.Environment.NewLine.

On Windows, this is equivalent to \r\n though it could be different under another .NET implementation, such as Mono on Linux, for example.

If tomorrow you decide you don't love Marry either she can be replaced as well:

Illegal offset type errors occur when you attempt to access an array index using an object or an array as the index key.

Example:

$x = new stdClass();
$arr = array();
echo $arr[$x];
//illegal offset type

Your $xml array contains an object or array at $xml->entry[$i]->source for some value of $i, and when you try to use that as an index key for $s, you get that warning. You'll have to make sure $xml contains what you want it to and that you're accessing it correctly.

There are 3 sources of variables in Ansible:

1. Variables gathered from facts. You can get them by running command: ansible -m setup hostname

2. Built-in (pre-defined) Ansible variables (AKA 'magic' variables). They are documented in Ansible documentation: http://docs.ansible.com/playbooks_variables.html#magic-variables-and-how-to-access-information-about-other-hosts
   Here is the list extracted from Ansible 1.9 documentation:

   • group_names
   • groups
   • inventory_hostname
   • ansible_hostname
   • inventory_hostname_short
   • play_hosts
   • delegate_to
   • inventory_dir
   • inventory_file
     
3. Variables passed to ansible via command line. But obviously you know what they are

I know this isn't a 'replacement' WebBrowser control, but I was having some awful rendering issues whilst showing a page that was using BootStrap 3+ for layout etc, and then I found a post that suggested I use the following. Apparently, it's specific to IE and tells it to use the latest variation found on the client machine for rendering (so it won't use IE7, which I believe is the default).

So just put:

<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

somewhere in the head part of your document.

Obviously, if it's not your document, this won't help - though I personally consider it to be a security hole if you're reading pages not created by yourself through the WebBrowser control - why not just use a web browser!

First check whether the folder name is right or wrong since while you copying to one folder from other accidently it takes other folder address eg it take C instead of F So from OPTION>DIRECTORY change the folder name

There is actually no need to check whether it exists or not. Since you already wants to create it if it exists , just mkdir will do

mkdir -p /home/mlzboy/b2c2/shared/db

no need for the padding or the corners.

here's a sample:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >

        android:angle="270"/>

Simple solution and understanding

To answer the question:

SELECT field,datetime_field 
FROM database
WHERE TO_CHAR(date_field, 'YYYYMMDD') = TO_CHAR(SYSDATE-1, 'YYYYMMDD');

Some explanation

If you have a field that is not in date format but want to compare using date i.e. field is considered as date but in number format e.g. 20190823 (YYYYMMDD)

SELECT * FROM YOUR_TABLE WHERE ID_DATE = TO_CHAR(SYSDATE-1, 'YYYYMMDD') 

If you have a field that is in date/timestamp format and you need to compare, Just change the format

SELECT TO_CHAR(SYSDATE-1, 'YYYY-MM-DD HH24:MI:SS')  FROM DUAL

IF you want to return it to date format

SELECT TO_DATE(TO_CHAR(SYSDATE-1, 'YYYY-MM-DD HH24:MI:SS'), 'YYYY-MM-DD HH24:MI:SS') AS NEW_DATE  FROM DUAL

Conclusion.

With this knowledge you can convert the filed you want to compare to a YYYYMMDD or YYYY-MM-DD or any year-month-date format then compare with the same sysdate format.

The C++ build system (compiler) knows no difference, so it's all one of conventions.

The convention is that .h files are declarations, and .cpp files are definitions.

That's why .h files are #included -- we include the declarations.

Considering the exact question, putting us in a "special" coordinates system where positive axis means moving DOWN (like a screen or an interface view), you need to adapt this function like this, and negative the Y coordinates:

Example in Swift 2.0

func angle_between_two_points(pa:CGPoint,pb:CGPoint)->Double{
    let deltaY:Double = (Double(-pb.y) - Double(-pa.y))
    let deltaX:Double = (Double(pb.x) - Double(pa.x))
    var a = atan2(deltaY,deltaX)
    while a < 0.0 {
        a = a + M_PI*2
    }
    return a
}

This function gives a correct answer to the question. Answer is in radians, so the usage, to view angles in degrees, is:

let p1 = CGPoint(x: 1.5, y: 2) //estimated coords of p1 in question
let p2 = CGPoint(x: 2, y : 3) //estimated coords of p2 in question

print(angle_between_two_points(p1, pb: p2) / (M_PI/180))
//returns 296.56

var DateDiff = function(type, start, end) {

    let // or var
        years = end.getFullYear() - start.getFullYear(),
        monthsStart = start.getMonth(),
        monthsEnd = end.getMonth()
    ;

    var returns = -1;

    switch(type){
        case 'm': case 'mm': case 'month': case 'months':
            returns = ( ( ( years * 12 ) - ( 12 - monthsEnd ) ) + ( 12 - monthsStart ) );
            break;
        case 'y': case 'yy': case 'year': case 'years':
            returns = years;
            break;
        case 'd': case 'dd': case 'day': case 'days':
            returns = ( ( end - start ) / ( 1000 * 60 * 60 * 24 ) );
            break;
    }

    return returns;

}

Usage

var qtMonths = DateDiff('mm', new Date('2015-05-05'), new Date());

var qtYears = DateDiff('yy', new Date('2015-05-05'), new Date());

var qtDays = DateDiff('dd', new Date('2015-05-05'), new Date());

OR

var qtMonths = DateDiff('m', new Date('2015-05-05'), new Date()); // m || y || d

var qtMonths = DateDiff('month', new Date('2015-05-05'), new Date()); // month || year || day

var qtMonths = DateDiff('months', new Date('2015-05-05'), new Date()); // months || years || days

...

var DateDiff = function (type, start, end) {

    let // or var
        years = end.getFullYear() - start.getFullYear(),
        monthsStart = start.getMonth(),
        monthsEnd = end.getMonth()
    ;

    if(['m', 'mm', 'month', 'months'].includes(type)/*ES6*/)
        return ( ( ( years * 12 ) - ( 12 - monthsEnd ) ) + ( 12 - monthsStart ) );
    else if(['y', 'yy', 'year', 'years'].includes(type))
        return years;
    else if (['d', 'dd', 'day', 'days'].indexOf(type) !== -1/*EARLIER JAVASCRIPT VERSIONS*/)
        return ( ( end - start ) / ( 1000 * 60 * 60 * 24 ) );
    else
        return -1;

I don't think you can!

/home/export/user1 $ sqlplus / 
> @script1.sql
> HOST CD /home/export/user2
> @script2.sql

script2.sql has to be in /home/export/user1.

You either use the full path, or exit the script and start sqlplus again from the right directory.

#!/bin/bash
oraenv .
cd /home/export/user1
sqlplus / @script1.sql
cd /home/export/user2
sqlplus / @script2.sql

traceback.format_exception

If you only have the exception object, you can get the traceback as a string from any point of the code in Python 3 with:

import traceback

''.join(traceback.format_exception(None, exc_obj, exc_obj.__traceback__))

Full example:

#!/usr/bin/env python3

import traceback

def f():
    g()

def g():
    raise Exception('asdf')

try:
    g()
except Exception as e:
    exc = e

tb_str = ''.join(traceback.format_exception(None, exc_obj, exc_obj.__traceback__))
print(tb_str)

Output:

Traceback (most recent call last):
  File "./main.py", line 12, in <module>
    g()
  File "./main.py", line 9, in g
    raise Exception('asdf')
Exception: asdf

Documentation: https://docs.python.org/3.7/library/traceback.html#traceback.format_exception

                it.replace(containerViewId, this, "Fr").commit()
            }
        }
    }
}

You can add a reference to System.Configuration in your project and then:

using System.Configuration;

then

string sValue = ConfigurationManager.AppSettings["BatchFile"];

with an app.config file like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
   <appSettings>
       <add key="BatchFile" value="blah.bat" />
   </appSettings>
</configuration>

Generally i live this situation when parent of my object is hidden. for example when the html is like this:

    <div class="div-parent" style="display:none">
        <div class="div-child" style="display:block">
        </div>
    </div>

if you ask if child is visible like:

    $(".div-child").is(":visible");

it will return false because its parent is not visible so that div wont be visible, also.

If your tables are on the same mysql server you can run the following

CREATE TABLE destination_db.my_table SELECT * FROM source_db.my_table;
ALTER TABLE destination_db.my_table ADD PRIMARY KEY (id); 
ALTER TABLE destination_db.my_table MODIFY COLUMN id INT AUTO_INCREMENT;

I think onSupportNavigateUp() is the best and Easiest way to do so, check the below steps. Step 1 is necessary, step two have alternative.

Step 1 showing back button: Add this line in onCreate() method to show back button.

assert getSupportActionBar() != null;   //null check
getSupportActionBar().setDisplayHomeAsUpEnabled(true);   //show back button

Step 2 implementation of back click: Override this method

@Override
public boolean onSupportNavigateUp() {  
    finish();  
    return true;  
}

thats it you are done
OR Step 2 Alternative: You can add meta to the activity in manifest file as

<meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value="MainActivity" />

Edit: If you are not using AppCompat Activity then do not use support word, you can use

getActionBar().setDisplayHomeAsUpEnabled(true); // In `OnCreate();`

// And override this method
@Override 
public boolean onNavigateUp() { 
     finish(); 
     return true; 
}

Thanks to @atariguy for comment.

Thanks to AddRange:

Example:

public class Person
{ 
    private string Name;
    private string FirstName;

    public Person(string name, string firstname) => (Name, FirstName) = (name, firstname);
}

To add multiple Person to a List<>:

List<Person> listofPersons = new List<Person>();
listofPersons.AddRange(new List<Person>
{
    new Person("John1", "Doe" ),
    new Person("John2", "Doe" ),
    new Person("John3", "Doe" ),
 });

I had ran into similar problem today. Tried all the above solutions but didn't worked. So posting my solution here.

For an inheritance-friendly implementation, check out Tal Cohen's solution, How Do I Correctly Implement the equals() Method?

Summary:

In his book Effective Java Programming Language Guide (Addison-Wesley, 2001), Joshua Bloch claims that "There is simply no way to extend an instantiable class and add an aspect while preserving the equals contract." Tal disagrees.

His solution is to implement equals() by calling another nonsymmetric blindlyEquals() both ways. blindlyEquals() is overridden by subclasses, equals() is inherited, and never overridden.

Example:

class Point {
    private int x;
    private int y;
    protected boolean blindlyEquals(Object o) {
        if (!(o instanceof Point))
            return false;
        Point p = (Point)o;
        return (p.x == this.x && p.y == this.y);
    }
    public boolean equals(Object o) {
        return (this.blindlyEquals(o) && o.blindlyEquals(this));
    }
}

class ColorPoint extends Point {
    private Color c;
    protected boolean blindlyEquals(Object o) {
        if (!(o instanceof ColorPoint))
            return false;
        ColorPoint cp = (ColorPoint)o;
        return (super.blindlyEquals(cp) && 
        cp.color == this.color);
    }
}

Note that equals() must work across inheritance hierarchies if the Liskov Substitution Principle is to be satisfied.

>>> source_list = ('1','a'),('2','b'),('3','c'),('4','d')
>>> list1, list2 = zip(*source_list)
>>> list1
('1', '2', '3', '4')
>>> list2
('a', 'b', 'c', 'd')

Edit: Note that zip(*iterable) is its own inverse:

>>> list(source_list) == zip(*zip(*source_list))
True

When unpacking into two lists, this becomes:

>>> list1, list2 = zip(*source_list)
>>> list(source_list) == zip(list1, list2)
True

Addition suggested by rocksportrocker.

Violating the Java naming conventions (variable names and method names start with lowercase, class names start with uppercase) is contributing to your confusion.

The variable Random is only "in scope" inside the main method. It's not accessible to any methods called by main. When you return from main, the variable disappears (it's part of the stack frame).

If you want all of the methods of your class to use the same Random instance, declare a member variable:

class MyObj {
  private final Random random = new Random();
  public void compTurn() {
    while (true) {
      int a = random.nextInt(10);
      if (possibles[a] == 1) 
        break;
    }
  }
}

You can use the following format to generate a tooltip for an image.

<div class="tooltip"><img src="joe.jpg" />
  <span class="tooltiptext">Tooltip text</span>
</div>

That you are running Windows. Read:

http://en.wikipedia.org/wiki/Sudo

It basically allows you to execute an application with elevated privileges. If you want to achieve a similar effect under Windows, open an administrative prompt and execute your command from there. Under Vista, this is easily done by opening the shortcut while holding Ctrl+Shift at the same time.

That being said, it might very well be possible that your account already has sufficient privileges, depending on how your OS is setup, and the Windows version used.

A Simple Approach will be to use a normal link and add Bootstrap modal effect to it. Just make use of my Code, hopefully you will get it run.

For --driver-class-path option you can use : as delimeter to pass multiple jars. Below is the example with spark-shell command but I guess the same should work with spark-submit as well

    spark-shell --driver-class-path /path/to/example.jar:/path/to/another.jar

Spark version: 2.2.0

Jonathon gave you an approach using dict comprehensions in his answer. Here is an approach that deals with your do something part.

If you want to do something with the values of the dictionary, you don't need a dictionary comprehension at all:

I'm using iteritems() since you tagged your question with python-2.7

results = map(some_function, [(k,v) for k,v in a_dict.iteritems() if 'foo' in k])

Now the result will be in a list with some_function applied to each key/value pair of the dictionary, that has foo in its key.

If you just want to deal with the values and ignore the keys, just change the list comprehension:

results = map(some_function, [v for k,v in a_dict.iteritems() if 'foo' in k])

some_function can be any callable, so a lambda would work as well:

results = map(lambda x: x*2, [v for k,v in a_dict.iteritems() if 'foo' in k])

The inner list is actually not required, as you can pass a generator expression to map as well:

>>> map(lambda a: a[0]*a[1], ((k,v) for k,v in {2:2, 3:2}.iteritems() if k == 2))
[4]

I created an extension method to the ObservableCollection

public static void MySort<TSource,TKey>(this ObservableCollection<TSource> observableCollection, Func<TSource, TKey> keySelector)
    {
        var a = observableCollection.OrderBy(keySelector).ToList();
        observableCollection.Clear();
        foreach(var b in a)
        {
            observableCollection.Add(b);
        }
    }

It seems to work and you don't need to implement IComparable

This happens because Apple's servers may not be working correctly. Just wait and try later or next time. It will work for sure eventually.

I am explaining, How to get current location and Directly move to the camera to current location with assuming that you have implemented map-v2. For more details, You can refer official doc.

Add location service in gradle

implementation "com.google.android.gms:play-services-location:11.0.1"

Add location permission in manifest file

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

Make sure you ask for RunTimePermission. I am using Ask-Permission for that. Its easy to use.

Now refer below code to get the current location and display it on a map.

private FusedLocationProviderClient mFusedLocationProviderClient;

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mFusedLocationProviderClient = LocationServices
                .getFusedLocationProviderClient(getActivity());

}

private void getDeviceLocation() {
        try {
            if (mLocationPermissionGranted) {
                Task<Location> locationResult = mFusedLocationProviderClient.getLastLocation();
                locationResult.addOnCompleteListener(new OnCompleteListener<Location>() {
                    @Override
                    public void onComplete(@NonNull Task<Location> task) {
                        if (task.isSuccessful()) {
                            // Set the map's camera position to the current location of the device.
                            Location location = task.getResult();
                            LatLng currentLatLng = new LatLng(location.getLatitude(),
                                    location.getLongitude());
                            CameraUpdate update = CameraUpdateFactory.newLatLngZoom(currentLatLng,
                                    DEFAULT_ZOOM);
                            googleMap.moveCamera(update);
                        }
                    }
                });
            }
        } catch (SecurityException e) {
            Log.e("Exception: %s", e.getMessage());
        }
}

When user granted location permission call above getDeviceLocation() method

private void updateLocationUI() {
        if (googleMap == null) {
            return;
        }
        try {
            if (mLocationPermissionGranted) {
                googleMap.setMyLocationEnabled(true);
                googleMap.getUiSettings().setMyLocationButtonEnabled(true);
                getDeviceLocation();
            } else {
                googleMap.setMyLocationEnabled(false);
                googleMap.getUiSettings().setMyLocationButtonEnabled(false);
            }
        } catch (SecurityException e) {
            Log.e("Exception: %s", e.getMessage());
        }
    }

I had the same error when installing dependencies in Angular. I've tried aforementioned techniques but none of them worked until I've deleted package-lock.json which was previously created when running Node v11.

Now I'm using Node v12 so this is how I got resolved.

I repeat if you have package-lock.json delete it, file and then install dependencies.

To pass some context data to javascript code, you have to serialize it in a way it will be "understood" by javascript (namely JSON). You also need to mark it as safe using the safe Jinja filter, to prevent your data from being htmlescaped.

You can achieve this by doing something like that:

The view

import json

@app.route('/')
def my_view():
    data = [1, 'foo']
    return render_template('index.html', data=json.dumps(data))

The template

<script type="text/javascript">
    function test_func(data) {
        console.log(data);
    }
    test_func({{ data|safe }})
</script>

Edit - exact answer

So, to achieve exactly what you want (loop over a list of items, and pass them to a javascript function), you'd need to serialize every item in your list separately. Your code would then look like this:

The view

import json

@app.route('/')
def my_view():
    data = [1, "foo"]
    return render_template('index.html', data=map(json.dumps, data))

The template

{% for item in data %}
    <span onclick=someFunction({{ item|safe }});>{{ item }}</span>
{% endfor %}

Edit 2

In my example, I use Flask, I don't know what framework you're using, but you got the idea, you just have to make it fit the framework you use.

Edit 3 (Security warning)

NEVER EVER DO THIS WITH USER-SUPPLIED DATA, ONLY DO THIS WITH TRUSTED DATA!

Otherwise, you would expose your application to XSS vulnerabilities!

In windows first check under services if world wide web publishing services is running. If not start it.

If you cannot find it switch on IIS features of windows: In 7,8,10 it is under control panel , "turn windows features on or off". Internet Information Services World Wide web services and Internet information Services Hostable Core are required. Not sure if there is another way to get it going on windows, but this worked for me for all browsers. You might need to add localhost or http:/127.0.0.1 to the trusted websites also under IE settings.

This is much easier in pandas now with drop_duplicates and the keep parameter.

import pandas as pd
df = pd.DataFrame({"A":["foo", "foo", "foo", "bar"], "B":[0,1,1,1], "C":["A","A","B","A"]})
df.drop_duplicates(subset=['A', 'C'], keep=False)

time1 is the key of the most outer dictionary, eg, feb2012. So then you're trying to index the string, but you can only do this with integers. I think what you wanted was:

for info in courses[time1][course]:

As you're going through each dictionary, you must add another nest.

If you just want to change the color of the row, you could just access the style.backgroundColor property and set it.

Here is a quick link to a CSS property to JS conversion.

as of now, you can use

<img src="{{ asset('images/foo.png') }}" alt="tag">

1) in a query window in SQL Server Management Studio, run the command:

SET SHOWPLAN_ALL ON

2) run your slow query

3) your query will not run, but the execution plan will be returned. store this output

4) run your fast version of the query

5) your query will not run, but the execution plan will be returned. store this output

6) compare the slow query version output to the fast query version output.

7) if you still don't know why one is slower, post both outputs in your question (edit it) and someone here can help from there.

Assuming you wanted to do this synchronously, using the WebClient.OpenRead(...) method and setting the timeout on the Stream that it returns will give you the desired result:

using (var webClient = new WebClient())
using (var stream = webClient.OpenRead(streamingUri))
{
     if (stream != null)
     {
          stream.ReadTimeout = Timeout.Infinite;
          using (var reader = new StreamReader(stream, Encoding.UTF8, false))
          {
               string line;
               while ((line = reader.ReadLine()) != null)
               {
                    if (line != String.Empty)
                    {
                        Console.WriteLine("Count {0}", count++);
                    }
                    Console.WriteLine(line);
               }
          }
     }
}

Deriving from WebClient and overriding GetWebRequest(...) to set the timeout @Beniamin suggested, didn't work for me as, but this did.

usually when i work with remote location teams it is important for me that i have prior knowledge what change done by other teams in same file, before i follow git stages untrack-->staged-->commit for that i wrote an bash script which help me to avoid unnecessary resolve merge conflict with remote team or make new local branch and compare and merge on main branch

#set -x 
branchname=`git branch | grep -F '*' |  awk '{print $2}'`
echo $branchname
git fetch origin ${branchname}
for file in `git status | grep "modified" | awk "{print $2}" `
do
echo "PLEASE CHECK OUT GIT DIFF FOR "$file 
git difftool FETCH_HEAD $file ;
done

in above script i fetch remote main branch (not necessary its master branch)to FETCH_HEAD them make a list of my modified file only and compare modified files to git difftool

here many difftool supported by git, i configure 'Meld Diff Viewer' for good GUI comparison .

Adding a bit to mitigate the confusion here. Even though Darren Davies' (accepted) answer is more straight forward, I think Andrei's answer is a better approach for MVC applications.

The answer from Andrei means that you can use HttpContext just as you would use System.Web.HttpContext.Current. For example, if you want to do this:

System.Web.HttpContext.Current.User.Identity.Name

you should instead do this:

HttpContext.User.Identity.Name

Both achieve the same result, but (again) in terms of MVC, the latter is more recommended.

Another good and also straight forward information regarding this matter can be found here: Difference between HttpContext.Current and Controller.Context in MVC ASP.NET.

According to the standard (§6.4.4.4/10)

The value of an integer character constant containing more than one character (e.g., 'ab'), [...] is implementation-defined.

long x = '\xde\xad\xbe\xef'; // yes, single quotes

This is valid ISO 9899:2011 C. It compiles without warning under gcc with -Wall, and a “multi-character character constant” warning with -pedantic.

From Wikipedia:

Multi-character constants (e.g. 'xy') are valid, although rarely useful — they let one store several characters in an integer (e.g. 4 ASCII characters can fit in a 32-bit integer, 8 in a 64-bit one). Since the order in which the characters are packed into one int is not specified, portable use of multi-character constants is difficult.

For portability sake, don't use multi-character constants with integral types.

ANDROID_HOME

Deprecated (in Android Studio), use ANDROID_SDK_ROOT instead.

ANDROID_SDK_ROOT

Installation directory of Android SDK package.

Example: C:\AndroidSDK or /usr/local/android-sdk/

ANDROID_NDK_ROOT

Installation directory of Android NDK package. (WITHOUT ANY SPACE)

Example: C:\AndroidNDK or /usr/local/android-ndk/

ANDROID_SDK_HOME

Location of SDK related data/user files.

Example: C:\Users\<USERNAME>\.android\ or ~/.android/

ANDROID_EMULATOR_HOME

Location of emulator-specific data files.

Example: C:\Users\<USERNAME>\.android\ or ~/.android/

ANDROID_AVD_HOME

Location of AVD-specific data files.

Example: C:\Users\<USERNAME>\.android\avd\ or ~/.android/avd/

JDK_HOME and JAVA_HOME

Installation directory of JDK (aka Java SDK) package.

Note: This is used to run Android Studio(and other Java-based applications). Actually when you run Android Studio, it checks for JDK_HOME then JAVA_HOME environment variables to use.

man printf.1 has a note at the bottom: "...your shell may have its own version of printf...". This question is tagged for bash, but if at all possible, I try to write scripts portable to any shell. dash is usually a good minimum baseline for portability - so the answer here works in bash, dash, & zsh. If a script works in those 3, it's most likely portable to just about anywhere.

The latest implementation of printf in dash^[1] doesn't colorize output given a %s format specifier with an ANSI escape character \e -- but, a format specifier %b combined with octal \033 (equivalent to an ASCII ESC) will get the job done. Please comment for any outliers, but AFAIK, all shells have implemented printf to use the ASCII octal subset at a bare minimum.

To the title of the question "Using colors with printf", the most portable way to set formatting is to combine the %b format specifier for printf (as referenced in an earlier answer from @Vlad) with an octal escape \033.

portable-color.sh

#/bin/sh
P="\033["
BLUE=34
printf "-> This is %s %-6s %s text \n" $P"1;"$BLUE"m" "blue" $P"0m"
printf "-> This is %b %-6s %b text \n" $P"1;"$BLUE"m" "blue" $P"0m"

Outputs:

$ ./portable-color.sh
-> This is \033[1;34m blue   \033[0m text
-> This is  blue    text

...and 'blue' is blue in the second line.

The %-6s format specifier from the OP is in the middle of the format string between the opening & closing control character sequences.

jstl-1.2.jar --> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
jstl-1.1.jar --> <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>

also please check for the dependency jars that you have added javax.servlet.jar and javax.servlet.jsp.jstl-1.2.1.jar or not in your WEB-INF/lib folder. In my case these two solved the issue.

Of course there is. Check out mysql_query, and mysql_fetch_row if you use MySQL.
Example from PHP manual:

<?php
$result = mysql_query("SELECT id,email FROM people WHERE id = '42'");
if (!$result) {
    echo 'Could not run query: ' . mysql_error();
    exit;
}
$row = mysql_fetch_row($result);

echo $row[0]; // 42
echo $row[1]; // the email value
?>

You can also clear the watch inside the callback if you want to clear it right after something happens. That way your $watch will stay active until used.

Like so...

var clearWatch = $scope.$watch('quartzCrystal', function( crystal ){
  if( isQuartz( crystal )){
    // do something special and then stop watching!

Swift 2.0+

AudioToolbox now presents the kSystemSoundID_Vibrate as a SystemSoundID type, so the code is:

import AudioToolbox.AudioServices

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)
AudioServicesPlayAlertSound(kSystemSoundID_Vibrate)

Instead of having to go thru the extra cast step

(Props to @Dov)

Original Answer (Swift 1.x)

And, here's how you do it on Swift (in case you ran into the same trouble as I did)

Link against AudioToolbox.framework (Go to your project, select your target, build phases, Link Binary with Libraries, add the library there)

Once that is completed:

import AudioToolbox.AudioServices

// Use either of these
AudioServicesPlaySystemSound(SystemSoundID(kSystemSoundID_Vibrate))
AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))

The cheesy thing is that SystemSoundID is basically a typealias (fancy swift typedef) for a UInt32, and the kSystemSoundID_Vibrate is a regular Int. The compiler gives you an error for trying to cast from Int to UInt32, but the error reads as "Cannot convert to SystemSoundID", which is confusing. Why didn't apple just make it a Swift enum is beyond me.

@aponomarenko's goes into the details, my answer is just for the Swifters out there.

That's not a rounding ploblem, that is a display problem. A number doesn't contain information about significant digits; the value 2 is the same as 2.0000000000000. It's when you turn the rounded value into a string that you have make it display a certain number of digits.

You could just add zeroes after the number, something like:

var s = number.toString();
if (s.indexOf('.') == -1) s += '.';
while (s.length < s.indexOf('.') + 4) s += '0';

(Note that this assumes that the regional settings of the client uses period as decimal separator, the code needs some more work to function for other settings.)

Use tags label and our method for =, is bound to input. If follow the rules of the form, and avoid confusion with tags, use the following:

<style type="text/css">
    label.lab:before { content: 'input: '; }
</style>

or compare (short code):

<style type="text/css">
    div label { content: 'input: '; color: red; }
</style>

form....

<label class="lab" for="single"></label><input name="n" id="single" ...><label for="single"> - simle</label>

or compare (short code):

<div><label></label><input name="n" ...></div>

You can also post multiple inputs with the same name and have them save into an array by adding empty square brackets to the input name like this:

<input type="text" name="comment[]" value="comment1"/>
<input type="text" name="comment[]" value="comment2"/>
<input type="text" name="comment[]" value="comment3"/>
<input type="text" name="comment[]" value="comment4"/>

If you use php:

print_r($_POST['comment']) 

you will get this:

Array ( [0] => 'comment1' [1] => 'comment2' [2] => 'comment3' [3] => 'comment4' )

On Google'e Gson library, for having a JsonObject, or more abstract a JsonElement:

import com.google.gson.JsonElement;
import com.google.gson.JsonParser;

JsonElement json = JsonParser.parseReader( new InputStreamReader(new FileInputStream("/someDir/someFile.json"), "UTF-8") );

This is not demanding a given Object structure for receiving/reading the json string.

Try javax.net.ssl.keyStorePassword instead of javax.net.ssl.keyPassword: the latter isn't mentioned in the JSSE ref guide.

The algorithms you mention should be there by default using the default security providers. NoSuchAlgorithmExceptions are often cause by other underlying exceptions (file not found, wrong password, wrong keystore type, ...). It's useful to look at the full stack trace.

You could also use -Djavax.net.debug=ssl, or at least -Djavax.net.debug=ssl,keymanager, to get more debugging information, if the information in the stack trace isn't sufficient.

Does anybody have any experience to share?

There are 2^122 possible values for a type-4 UUID. (The spec says that you lose 2 bits for the type, and a further 4 bits for a version number.)

Assuming that you were to generate 1 million random UUIDs a second, the chances of a duplicate occurring in your lifetime would be vanishingly small. And to detect the duplicate, you'd have to solve the problem of comparing 1 million new UUIDs per second against all of the UUIDs you have previously generated¹!

The chances that anyone has experienced (i.e. actually noticed) a duplicate in real life are even smaller than vanishingly small ... because of the practical difficulty of looking for collisions.

Now of course, you will typically be using a pseudo-random number generator, not a source of truly random numbers. But I think we can be confident that if you are using a creditable provider for your cryptographic strength random numbers, then it will be cryptographic strength, and the probability of repeats will be the same as for an ideal (non-biased) random number generator.

However, if you were to use a JVM with a "broken" crypto- random number generator, all bets are off. (And that might include some of the workarounds for "shortage of entropy" problems on some systems. Or the possibility that someone has tinkered with your JRE, either on your system or upstream.)

^{1 - Assuming that you used "some kind of binary btree" as proposed by an anonymous commenter, each UUID is going to need O(NlogN) bits of RAM memory to represent N distinct UUIDs assuming low density and random distribution of the bits. Now multiply that by 1,000,000 and the number of seconds that you are going to run the experiment for. I don't think that is practical for the length of time needed to test for collisions of a high quality RNG. Not even with (hypothetical) clever representations.}

You could use the SizeMode property of the PictureBox Control and set it to Center. This will match the center of your image to the center of your picture box.

pictureBox1.SizeMode = PictureBoxSizeMode.CenterImage;

Hope it could help.

Two main reasons:

1) mysql-server isn't installed! You have to install it (mysql-server and not mysql-client) and run it.

2) It's installed by default and running. So, it's not possible to run it again through Xampp or Lampp. You have to stop it: sudo service mysql stop

then you can start it through Xampp. It's possible to check if it's running or not with this code: sudo netstat -tap | grep mysql

If you see a result like this: tcp 0 0 localhost:mysql : LISTEN 1043/mysqld

It means that it's running properly.

It is ||, for example:

select 'Mr ' || ename from emp;

The only "interesting" feature I can think of is that 'x' || null returns 'x', not null as you might perhaps expect.

Change

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

To:

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

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

there is a CDP Studio IDE available that makes cross compile and deploy quite simple from both windows and linux and you can just check the raspberry toolchain checkbox during the installation. (PS. it has GPIO and I2C support so no code is needed to access those)

The IDE demo of raspberry use is up here: https://youtu.be/4SVZ68sQz5U

and you can download the IDE here: https://cdpstudio.com/home-edition

If you use git config user.email "[email protected]" it will be bound to the current project you are in.

That is what I do for my projects. I set the appropriate identity when I clone/init the repo. It is not fool-proof (if you forget and push before you figure it out you are hosed) but it is about as good as you can get without the ability to say git config --global user.email 'ILLEGAL_VALUE'

Actually, you can make an illegal value. Set your git config --global user.name $(perl -e 'print "x"x968;')

Then if you forget to set your non-global values you will get an error message.

[EDIT] On a different system I had to increase the number of x to 968 to get it to fail with "fatal: Impossibly long personal identifier". Same version of git. Strange.

Another clean way to save the file is this:

import csv
import urllib

urllib.retrieve("your url goes here" , "output.csv")

As mentioned in the comments, you need to install the python-qt4 package - no need to recompile it yourself.

sudo apt-get install python-qt4

You can also try below:

Map.Entry<String, Integer> entry = myMap.firstEntry();
System.out.println("First Value = " + entry);

I'm guessing

x= data[:,0]
y= data[:,1]

put the dll in system32 or syswow32 directory, and use appropriate regsvr32 to register it. wiered that even though it gave failed to register error, I rebooted my WIN 7 64 AND my vb app loaded the dll just fine!!
