Just grep through the working directory and send the output through the xargs command:

grep -lr '<<<<<<<' . | xargs git checkout --ours

or

grep -lr '<<<<<<<' . | xargs git checkout --theirs

How this works: grep will search through every file in the current directory (the .) and subdirectories recursively (the -r flag) looking for conflict markers (the string '<<<<<<<')

the -l or --files-with-matches flag causes grep to output only the filename where the string was found. Scanning stops after first match, so each matched file is only output once.

The matched file names are then piped to xargs, a utility that breaks up the piped input stream into individual arguments for git checkout --ours or --theirs

Since it would be very inconvenient to have to type this every time at the command line, if you do find yourself using it a lot, it might not be a bad idea to create an alias for your shell of choice: Bash is the usual one.

This method should work through at least Git versions 2.4.x

If you have control over the HTML then you could add a real element instead of a pseudo one. :before and :after pseudo elements are rendered right after the open tag or right before the close tag. The inline equivalent for this css

td { text-align: justify; }
td:after { content: ""; display: inline-block; width: 100%; }

Would be something like this:

<table>
<tr>
<td style="text-align: justify;">
TD Content
<span class="inline_td_after" style="display: inline-block; width: 100%;"></span>
</td>
</tr>
</table>

Keep in mind; Your "real" before and after elements and anything with inline css will greatly increase the size of your pages and ignore page load optimizations that external css and pseudo elements make possible.

I ran into a similar problem and have developed two standalone tools to accomplish this:

• CjsSS.js is a Vanilla Javascript tool (so no external dependencies) that supports back to IE6.

• ngCss is an Angular Module+Filter+Factory (aka: plugin) that supports Angular 1.2+ (so back to IE8)

Both of these tool sets allow you to do this in a STYLE tag or within an external *.css file:

    /*<script src='some.js'></script>
    <script>
        var mainColor = "#cccccc";
    </script>*/

    BODY {
        color: /*{{mainColor}}*/;
    }

And this in your on-page style attributes:

    <div style="color: {{mainColor}}" cjsss="#sourceCSS">blah</div>

or

    <div style="color: {{mainColor}}" ng-css="sourceCSS">blah</div>

NOTE: In ngCss, you could also do $scope.mainColor in place of var mainColor

By default, the Javascript is executed in a sandboxed IFRAME, but since you author your own CSS and host it on your own server (just like your *.js files) then XSS isn't an issue. But the sandbox provides that much more security and peace of mind.

CjsSS.js and ngCss fall somewhere in-between the other tools around to accomplish similar tasks:

• LESS, SASS and Stylus are all Preprocessors only and require you to learn a new language and mangle your CSS. Basically they extended CSS with new language features. All are also limited to plugins developed for each platform while CjsSS.js and ngCss both allow you to include any Javascript library via <script src='blah.js'></script> straight in your CSS!

• AbsurdJS saw the same problems and went the exact opposite direction of the Preprocessors above; rather than extending CSS, AbsurdJS created a Javascript library to generate CSS.

CjsSS.js and ngCss took the middle ground; you already know CSS, you already know Javascript, so just let them work together in a simple, intuitive way.

do the same thing and have no difference working wise. In your case you just have a typo. You have misspelled trustStore in javax.net.ssl.trustStore.

I also did not know how to do this until I thought of using PHP array's. And I am pretty sure this is the simplest way of generating a random string or number with array's. The code:

function randstr ($len=10, $abc="aAbBcCdDeEfFgGhHiIjJkKlLmMnNoOpPqQrRsStTuUvVwWxXyYzZ0123456789") {
    $letters = str_split($abc);
    $str = "";
    for ($i=0; $i<=$len; $i++) {
        $str .= $letters[rand(0, count($letters)-1)];
    };
    return $str;
};

You can use this function like this

randstr(20)     // returns a random 20 letter string
                // Or like this
randstr(5, abc) // returns a random 5 letter string using the letters "abc"

This returns addresses from any interfaces that have gateway addresses and unicast addresses in two separate lists, IPV4 and IPV6.

public static (List<IPAddress> V4, List<IPAddress> V6) GetLocal()
{
    List<IPAddress> foundV4 = new List<IPAddress>();
    List<IPAddress> foundV6 = new List<IPAddress>();

    NetworkInterface.GetAllNetworkInterfaces().ToList().ForEach(ni =>
    {
        if (ni.GetIPProperties().GatewayAddresses.FirstOrDefault() != null)
        {
            ni.GetIPProperties().UnicastAddresses.ToList().ForEach(ua =>
            {
                if (ua.Address.AddressFamily == AddressFamily.InterNetwork) foundV4.Add(ua.Address);
                if (ua.Address.AddressFamily == AddressFamily.InterNetworkV6) foundV6.Add(ua.Address);
            });
        }
    });

    return (foundV4.Distinct().ToList(), foundV6.Distinct().ToList());
}

You can read more about function types in the language specification in sections 3.5.3.5 and 3.5.5.

The TypeScript compiler will infer types when it can, and this is done you do not need to specify explicit types. so for the greeter example, greet() returns a string literal, which tells the compiler that the type of the function is a string, and no need to specify a type. so for instance in this sample, I have the greeter class with a greet method that returns a string, and a variable that is assigned to number literal. the compiler will infer both types and you will get an error if you try to assign a string to a number.

class Greeter {
    greet() {
        return "Hello, ";  // type infered to be string
    }
} 

var x = 0; // type infered to be number

// now if you try to do this, you will get an error for incompatable types
x = new Greeter().greet(); 

Similarly, this sample will cause an error as the compiler, given the information, has no way to decide the type, and this will be a place where you have to have an explicit return type.

function foo(){
    if (true)
        return "string"; 
    else 
        return 0;
}

This, however, will work:

function foo() : any{
    if (true)
        return "string"; 
    else 
        return 0;
}

application/javascript is the correct type to use but since it's not supported by IE6-8 you're going to be stuck with text/javascript. If you don't care about validity (HTML5 excluded) then just don't specify a type.

Yes, you can actually with CSS 2D Transforms. This is supported in almost all modern browsers, including IE9+. Here's an example.

HTML

<p>I feel like <span class="stretch">stretching</span>.</p>

CSS

span.stretch {
    display:inline-block;
    -webkit-transform:scale(2,1); /* Safari and Chrome */
    -moz-transform:scale(2,1); /* Firefox */
    -ms-transform:scale(2,1); /* IE 9 */
    -o-transform:scale(2,1); /* Opera */
    transform:scale(2,1); /* W3C */
}

TIP: You may need to add margin to your stretched text to prevent text collisions.

A .java file is the code file. A .class file is the compiled file.

It's not exactly "conversion" - it's compilation. Suppose your file was called "herb.java", you would write (in the command prompt):

 javac herb.java

It will create a herb.class file in the current folder.

It is "executable" only if it contains a static void main(String[]) method inside it. If it does, you can execute it by running (again, command prompt:)

 java herb

The bit shifting operators do exactly what their name implies. They shift bits. Here's a brief (or not-so-brief) introduction to the different shift operators.

The Operators

• >> is the arithmetic (or signed) right shift operator.
• >>> is the logical (or unsigned) right shift operator.
• << is the left shift operator, and meets the needs of both logical and arithmetic shifts.

All of these operators can be applied to integer values (int, long, possibly short and byte or char). In some languages, applying the shift operators to any datatype smaller than int automatically resizes the operand to be an int.

Note that <<< is not an operator, because it would be redundant.

Also note that C and C++ do not distinguish between the right shift operators. They provide only the >> operator, and the right-shifting behavior is implementation defined for signed types. The rest of the answer uses the C# / Java operators.

(In all mainstream C and C++ implementations including GCC and Clang/LLVM, >> on signed types is arithmetic. Some code assumes this, but it isn't something the standard guarantees. It's not undefined, though; the standard requires implementations to define it one way or another. However, left shifts of negative signed numbers is undefined behaviour (signed integer overflow). So unless you need arithmetic right shift, it's usually a good idea to do your bit-shifting with unsigned types.)

Left shift (<<)

Integers are stored, in memory, as a series of bits. For example, the number 6 stored as a 32-bit int would be:

00000000 00000000 00000000 00000110

Shifting this bit pattern to the left one position (6 << 1) would result in the number 12:

00000000 00000000 00000000 00001100

As you can see, the digits have shifted to the left by one position, and the last digit on the right is filled with a zero. You might also note that shifting left is equivalent to multiplication by powers of 2. So 6 << 1 is equivalent to 6 * 2, and 6 << 3 is equivalent to 6 * 8. A good optimizing compiler will replace multiplications with shifts when possible.

Non-circular shifting

Please note that these are not circular shifts. Shifting this value to the left by one position (3,758,096,384 << 1):

11100000 00000000 00000000 00000000

results in 3,221,225,472:

11000000 00000000 00000000 00000000

The digit that gets shifted "off the end" is lost. It does not wrap around.

Logical right shift (>>>)

A logical right shift is the converse to the left shift. Rather than moving bits to the left, they simply move to the right. For example, shifting the number 12:

00000000 00000000 00000000 00001100

to the right by one position (12 >>> 1) will get back our original 6:

00000000 00000000 00000000 00000110

So we see that shifting to the right is equivalent to division by powers of 2.

Lost bits are gone

However, a shift cannot reclaim "lost" bits. For example, if we shift this pattern:

00111000 00000000 00000000 00000110

to the left 4 positions (939,524,102 << 4), we get 2,147,483,744:

10000000 00000000 00000000 01100000

and then shifting back ((939,524,102 << 4) >>> 4) we get 134,217,734:

00001000 00000000 00000000 00000110

We cannot get back our original value once we have lost bits.

Arithmetic right shift (>>)

The arithmetic right shift is exactly like the logical right shift, except instead of padding with zero, it pads with the most significant bit. This is because the most significant bit is the sign bit, or the bit that distinguishes positive and negative numbers. By padding with the most significant bit, the arithmetic right shift is sign-preserving.

For example, if we interpret this bit pattern as a negative number:

10000000 00000000 00000000 01100000

we have the number -2,147,483,552. Shifting this to the right 4 positions with the arithmetic shift (-2,147,483,552 >> 4) would give us:

11111000 00000000 00000000 00000110

or the number -134,217,722.

So we see that we have preserved the sign of our negative numbers by using the arithmetic right shift, rather than the logical right shift. And once again, we see that we are performing division by powers of 2.

From the Docs: http://facebook.github.io/react-native/docs/running-on-device.html#method-2-connect-via-wi-fi

Method 2: Connect via Wi-Fi

You can also connect to the development server over Wi-Fi. You'll
first need to install the app on your device using a USB cable, but
once that has been done you can debug wirelessly by following these
instructions. You'll need your development machine's current IP
address before proceeding.

Open a terminal and type /sbin/ifconfig to find your machine's IP address.

1. Make sure your laptop and your phone are on the same Wi-Fi network.
2. Open your React Native app on your device.
3. You'll see a red screen with an error. This is OK. The following steps will fix that.
4. Open the in-app Developer menu.
5. Go to Dev Settings ? Debug server host for device.
6. Type in your machine's IP address and the port of the local dev server (e.g. 10.0.1.1:8081).
7. Go back to the Developer menu and select Reload JS.

Not sure if there is universally accepted standard but my own preferences are;

• constructors first
• static methods next, if there is a main method, always before other static methods
• non static methods next, usually in order of the significance of the method followed by any methods that it calls. This means that public methods that call other class methods appear towards the top and private methods that call no other methods usually end up towards the bottom
• standard methods like toString, equals and hashcode next
• getters and setters have a special place reserved right at the bottom of the class

As I know, the best sorting algorithm is O(n*log n), whatever the container - it's been proved that sorting in the broad sense of the word (mergesort/quicksort etc style) can't go lower. Using a linked list will not give you a better run time.

The only one algorithm which runs in O(n) is a "hack" algorithm which relies on counting values rather than actually sorting.

If your Manifest.xml has the default android:theme="@style/AppTheme"

Go to res/values/styles.xml and change

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

to

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

And the ActionBar is disappeared!

By using synchronized on a static method lock you will synchronize the class methods and attributes ( as opposed to instance methods and attributes )

So your assumption is correct.

I am wondering if making the method synchronized is the right approach to ensure thread-safety.

Not really. You should let your RDBMS do that work instead. They are good at this kind of stuff.

The only thing you will get by synchronizing the access to the database is to make your application terribly slow. Further more, in the code you posted you're building a Session Factory each time, that way, your application will spend more time accessing the DB than performing the actual job.

Imagine the following scenario:

Client A and B attempt to insert different information into record X of table T.

With your approach the only thing you're getting is to make sure one is called after the other, when this would happen anyway in the DB, because the RDBMS will prevent them from inserting half information from A and half from B at the same time. The result will be the same but only 5 times ( or more ) slower.

Probably it could be better to take a look at the "Transactions and Concurrency" chapter in the Hibernate documentation. Most of the times the problems you're trying to solve, have been solved already and a much better way.

Actually, you can, even though accepted answer saying that you can't.

There is a _JAVA_OPTIONS environment variable, more about it here

Read up the concept of a name space. When you assign a variable in a function, you only assign it in the namespace of this function. But clearly you want to use it between all functions.

def defineAList():
    #list = ['1','2','3'] this creates a new list, named list in the current namespace.
    #same name, different list!

    list.extend['1', '2', '3', '4'] #this uses a method of the existing list, which is in an outer namespace
    print "For checking purposes: in defineAList, list is",list
    return list

Alternatively, you can pass it around:

def main():
    new_list = defineAList()
    useTheList(new_list)

MSTest has a powerful attribute called DataSource. Using this you can perform data-driven tests as you asked. You can have your test data in XML, CSV, or in a database. Here are few links that will guide you

Here's an example of using the HttpWebRequest class to fetch a URL

private void buttonl_Click(object sender, EventArgs e) 
{ 
    String url = TextBox_url.Text;
    HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url); 
    HttpWebResponse response = (HttpWebResponse) request.GetResponse(); 
    StreamReader sr = new StreamReader(response.GetResponseStream()); 
    richTextBox1.Text = sr.ReadToEnd(); 
    sr.Close(); 
} 

Try this:

  $('.select').on('select2:selecting select2:unselecting', function(e) {

      var value = e.params.args.data.id;

  });

    //create TreeMap instance
    TreeMap treeMap = new TreeMap();

    //add key value pairs to TreeMap
    treeMap.put("1","One");
    treeMap.put("2","Two");
    treeMap.put("3","Three");

    /*
      get Collection of values contained in TreeMap using
      Collection values()        
    */
    Collection c = treeMap.values();

    //obtain an Iterator for Collection
    Iterator itr = c.iterator();

    //iterate through TreeMap values iterator
    while(itr.hasNext())
      System.out.println(itr.next());

or:

   for (Map.Entry<K,V> entry : treeMap.entrySet()) {
        V value = entry.getValue();
        K key = entry.getKey();
   }

or:

   // Use iterator to display the keys and associated values
   System.out.println("Map Values Before: ");
   Set keys = map.keySet();
   for (Iterator i = keys.iterator(); i.hasNext();) {
     Integer key = (Integer) i.next();
     String value = (String) map.get(key);
     System.out.println(key + " = " + value);
   }

You could use System.Linq like this:

if (dataRows != null && dataRows.Length > 0)
{
   dataTable = dataRows.AsEnumerable().CopyToDataTable();
}

this seems to work fine :

dataframe.axes[0].tolist()

/test.html#alert('heello')

test.html
<button onClick="eval(document.location.hash.substring(1))">do it</button>

Enum singleton

The simplest way to implement a Singleton that is thread-safe is using an Enum

public enum SingletonEnum {
  INSTANCE;
  public void doSomething(){
    System.out.println("This is a singleton");
  }
}

This code works since the introduction of Enum in Java 1.5

Double checked locking

If you want to code a “classic” singleton that works in a multithreaded environment (starting from Java 1.5) you should use this one.

public class Singleton {

  private static volatile Singleton instance = null;

  private Singleton() {
  }

  public static Singleton getInstance() {
    if (instance == null) {
      synchronized (Singleton.class){
        if (instance == null) {
          instance = new Singleton();
        }
      }
    }
    return instance ;
  }
}

This is not thread-safe before 1.5 because the implementation of the volatile keyword was different.

Early loading Singleton (works even before Java 1.5)

This implementation instantiates the singleton when the class is loaded and provides thread safety.

public class Singleton {

  private static final Singleton instance = new Singleton();

  private Singleton() {
  }

  public static Singleton getInstance() {
    return instance;
  }

  public void doSomething(){
    System.out.println("This is a singleton");
  }

}

I modified the above technique which was close to what I wanted for angular and turned it into a service :-). I included ie9 because I was having some issues in my angularjs app, but could be something I'm doing, so feel free to take it out.

angular.module('myModule').service('browserDetectionService', function() {

 return {
isCompatible: function () {

  var browserInfo = navigator.userAgent;
  var browserFlags =  {};

  browserFlags.ISFF = browserInfo.indexOf('Firefox') != -1;
  browserFlags.ISOPERA = browserInfo.indexOf('Opera') != -1;
  browserFlags.ISCHROME = browserInfo.indexOf('Chrome') != -1;
  browserFlags.ISSAFARI = browserInfo.indexOf('Safari') != -1 && !browserFlags.ISCHROME;
  browserFlags.ISWEBKIT = browserInfo.indexOf('WebKit') != -1;

  browserFlags.ISIE = browserInfo.indexOf('Trident') > 0 || navigator.userAgent.indexOf('MSIE') > 0;
  browserFlags.ISIE6 = browserInfo.indexOf('MSIE 6') > 0;
  browserFlags.ISIE7 = browserInfo.indexOf('MSIE 7') > 0;
  browserFlags.ISIE8 = browserInfo.indexOf('MSIE 8') > 0;
  browserFlags.ISIE9 = browserInfo.indexOf('MSIE 9') > 0;
  browserFlags.ISIE10 = browserInfo.indexOf('MSIE 10') > 0;
  browserFlags.ISOLD = browserFlags.ISIE6 || browserFlags.ISIE7 || browserFlags.ISIE8 || browserFlags.ISIE9; // MUST be here

  browserFlags.ISIE11UP = browserInfo.indexOf('MSIE') == -1 && browserInfo.indexOf('Trident') > 0;
  browserFlags.ISIE10UP = browserFlags.ISIE10 || browserFlags.ISIE11UP;
  browserFlags.ISIE9UP = browserFlags.ISIE9 || browserFlags.ISIE10UP;

  return !browserFlags.ISOLD;
  }
};

});

The correct solution seems to be:

string text = ((ListBoxItem)ListBox1.SelectedItem).Content.ToString();

Please be sure to use .Content and not .Name.

I ended up using a normal hyperlink along with Url.Action, as in:

<a href='<%= Url.Action("Show", new { controller = "Browse", id = node.Id }) %>'
  data-nodeId='<%= node.Id %>'>
  <%: node.Name %>
</a>

It's uglier, but you've got a little more control over the a tag, which is sometimes useful in heavily AJAXified sites.

In case of using Mysql query browser, SET FOREIGN_KEY_CHECKS=0; does not have any impact in version 1.1.20. However, it works fine on Mysql query browser 1.2.17

The code in elyase's answer https://stackoverflow.com/a/27928411/4240413 does not actually work. Notice that sse is a scalar, and then it tries to iterate through it. The following code is a modified version. Not amazingly clean, but I think it works more or less.

class LinearRegression(linear_model.LinearRegression):

    def __init__(self,*args,**kwargs):

• http://jquery.com/download/
• https://code.jquery.com/

• Download latest version using this link

• http://code.jquery.com/jquery-latest.min.js (never use this link on production server)

Your code placement can look something like this

• Your Jquery should be included before using it any where else it will throw an error

Although it seems a dead thread, someone might find it useful

In both Visual Basic 6.0 and VB.NET you would use:

• Exit For to break from For loop
• Wend to break from While loop
• Exit Do to break from Do loop

depending on the loop type. See Exit Statements for more details.

Just answering the second part of your question about getting the name of the sheet where a table is:

Dim name as String

name = Range("Table1").Worksheet.Name

Edit:

To make things more clear: someone suggested that to use Range on a Sheet object. In this case, you need not; the Range where the table lives can be obtained using the table's name; this name is available throughout the book. So, calling Range alone works well.

Just put an override method named getItemId Get it by right click>generate>override methods>getItemId Put this method in the Adapter class

This command usually works on the MongoDB shell once you have switched to the database.

Check for the existence by retrieving its object_id:

if object_id('tempdb..##clients_keyword') is not null
    drop table ##clients_keyword

If everything you want to drop is owned by the same user, then you can use:

drop owned by the_user;

This will drop everything that the user owns.

That includes materialized views, views, sequences, triggers, schemas, functions, types, aggregates, operators, domains and so on (so, really: everything) that the_user owns (=created).

You have to replace the_user with the actual username, currently there is no option to drop everything for "the current user". The upcoming 9.5 version will have the option drop owned by current_user.

I found the problem that was causing the HTTP error.

In the setFalse() function that is triggered by the Save button my code was trying to submit the form that contained the button.

        function setFalse(){
            document.getElementById("hasId").value ="false";
            document.deliveryForm.submit();
            document.submitForm.submit();

when I remove the document.submitForm.submit(); it works:

        function setFalse(){
            document.getElementById("hasId").value ="false";
            document.deliveryForm.submit()

@Roger Lindsjö Thank you for spotting my error where I wasn't passing on the right parameter!

If someone is still looking for an answer, for me the problem was in routes/web.php file. Example:

Route::get('/', function () {
    return view('welcome');
});

It is also Route, so yeah...Just remove it if not needed and you are good to go! You should also follow answers provided from above.

I really struggled with this concept for a while when learning (still learning) MVVM. What I decided, and what I think others already decided but which wasn't clear to me is this:

My original thought was that a ViewModel should not be allowed to call a dialog box directly as it has no business deciding how a dialog should appear. Beacause of this I started thinking about how I could pass messages much like I would have in MVP (i.e. View.ShowSaveFileDialog()). However, I think this is the wrong approach.

It is OK for a ViewModel to call a dialog directly. However, when you are testing a ViewModel , that means that the dialog will either pop up during your test, or fail all together (never really tried this).

So, what needs to happen is while testing is to use a "test" version of your dialog. This means that for ever dialog you have, you need to create an Interface and either mock out the dialog response or create a testing mock that will have a default behaviour.

You should already be using some sort of Service Locator or IoC that you can configure to provide you the correct version depending on the context.

Using this approach, your ViewModel is still testable and depending on how you mock out your dialogs, you can control the behaviour.

Hope this helps.

I am using Camel route umarshal(xmljson) -> to(xlst) -> marshal(xmljson). Efficient enough (though not 100% perfect), but simple, if you are already using Camel.

Good Luck

IMO code with a stand-alone SELECT used to check to see if a row exists in a table is not taking proper advantage of the database. In your example you've got a hard-coded ID value but that's not how apps work in "the real world" (at least not in my world - yours may be different :-). In a typical app you're going to use a cursor to find data - so let's say you've got an app that's looking at invoice data, and needs to know if the customer exists. The main body of the app might be something like

FOR aRow IN (SELECT * FROM INVOICES WHERE DUE_DATE < TRUNC(SYSDATE)-60)
LOOP
  -- do something here
END LOOP;

and in the -- do something here you want to find if the customer exists, and if not print an error message.

One way to do this would be to put in some kind of singleton SELECT, as in

-- Check to see if the customer exists in PERSON

BEGIN
  SELECT 'TRUE'
    INTO strCustomer_exists
    FROM PERSON
    WHERE PERSON_ID = aRow.CUSTOMER_ID;
EXCEPTION
  WHEN NO_DATA_FOUND THEN
    strCustomer_exists := 'FALSE';
END;

IF strCustomer_exists = 'FALSE' THEN
  DBMS_OUTPUT.PUT_LINE('Customer does not exist!');
END IF;

but IMO this is relatively slow and error-prone. IMO a Better Way (tm) to do this is to incorporate it in the main cursor:

FOR aRow IN (SELECT i.*, p.ID AS PERSON_ID
               FROM INVOICES i
               LEFT OUTER JOIN PERSON p
                 ON (p.ID = i.CUSTOMER_PERSON_ID)
               WHERE DUE_DATA < TRUNC(SYSDATE)-60)
LOOP
  -- Check to see if the customer exists in PERSON

  IF aRow.PERSON_ID IS NULL THEN
    DBMS_OUTPUT.PUT_LINE('Customer does not exist!');
  END IF;
END LOOP;

This code counts on PERSON.ID being declared as the PRIMARY KEY on PERSON (or at least as being NOT NULL); the logic is that if the PERSON table is outer-joined to the query, and the PERSON_ID comes up as NULL, it means no row was found in PERSON for the given CUSTOMER_ID because PERSON.ID must have a value (i.e. is at least NOT NULL).

Share and enjoy.

Really depends on the overall structure of your document.

If you have:

<div></div>
<div></div>
<div></div>

it may be as simple as traversing through using

mydiv.nextSibling;
mydiv.previousSibling;

However, if the 'next' div could be anywhere in the document you'll need a more complex solution. You could try something using

document.getElementsByTagName("div");

and running through these to get where you want somehow.

If you are doing lots of complex DOM traversing such as this I would recommend looking into a library such as jQuery.

This is the simplest way I found for doing this:

byte[] byteArray = ...
InputStream is = new BufferedInputStream(new ByteArrayInputStream(byteArray));
String mimeType = URLConnection.guessContentTypeFromStream(is);

Brian Cauthon's answer is excellent! Just a little update, for EF 6, the class got moved to another namespace. So, before EF 6, you should include:

System.Data.Objects.SqlClient

If you update to EF 6, or simply are using this version, include:

System.Data.Entity.SqlServer

By including the incorrect namespace with EF6, the code will compile just fine but will throw a runtime error. I hope this note helps to avoid some confusion.

You can use \r to go to next line while filling up the UILabel using NSString.

UILabel * label;


label.text = [NSString stringWithFormat:@"%@ \r %@",@"first line",@"seconcd line"];

I am not getting your question properly but as per your heading, you can convert any type of object to string by using toString() function on a String Object.

In operating systems like Ubuntu python comes preinstalled. So the default version is python 2.7 you can confirm the version by typing below command in your terminal

python -V

if you installed it but didn't set default version you will see

python 2.7

in terminal. I will tell you how to set the default python version in Ubuntu.

A simple safe way would be to use an alias. Place this into ~/.bashrc or ~/.bash_aliases file:

alias python=python3

After adding the above in the file, run the command below:

source ~/.bash_aliases or source ~/.bashrc

now check python version again using python -V

if python version 3.x.x one, then the error is in your syntax like using print with parenthesis. change it to

test = input("enter the test")
print(test)

Disabling pyright worked perfectly for me on VS.

Yes.

new ArrayList<String>(){{
   add("A");
   add("B");
}}

What this is actually doing is creating a class derived from ArrayList<String> (the outer set of braces do this) and then declare a static initialiser (the inner set of braces). This is actually an inner class of the containing class, and so it'll have an implicit this pointer. Not a problem unless you want to serialise it, or you're expecting the outer class to be garbage collected.

I understand that Java 7 will provide additional language constructs to do precisely what you want.

EDIT: recent Java versions provide more usable functions for creating such collections, and are worth investigating over the above (provided at a time prior to these versions)

` Please include either of these:

`#include<sstream>`

using std::istringstream; 

Here is the JavaScript version guys and gals

function distanceTo(lat1, lon1, lat2, lon2, unit) {
      var rlat1 = Math.PI * lat1/180
      var rlat2 = Math.PI * lat2/180
      var rlon1 = Math.PI * lon1/180
      var rlon2 = Math.PI * lon2/180
      var theta = lon1-lon2
      var rtheta = Math.PI * theta/180
      var dist = Math.sin(rlat1) * Math.sin(rlat2) + Math.cos(rlat1) * Math.cos(rlat2) * Math.cos(rtheta);
      dist = Math.acos(dist)
      dist = dist * 180/Math.PI
      dist = dist * 60 * 1.1515
      if (unit=="K") { dist = dist * 1.609344 }
      if (unit=="N") { dist = dist * 0.8684 }
      return dist
}

For the sake of completeness, here is the ‘one-liner’ corresponding to @prunge’s excellent answer:

User user1 = users.stream()
        .filter(user -> user.getId() == 1)
        .reduce((a, b) -> {
            throw new IllegalStateException("Multiple elements: " + a + ", " + b);
        })
        .get();

This obtains the sole matching element from the stream, throwing

• NoSuchElementException in case the stream is empty, or
• IllegalStateException in case the stream contains more than one matching element.

A variation of this approach avoids throwing an exception early and instead represents the result as an Optional containing either the sole element, or nothing (empty) if there are zero or multiple elements:

Optional<User> user1 = users.stream()
        .filter(user -> user.getId() == 1)
        .collect(Collectors.reducing((a, b) -> null));

A nice way of doing this is to use the addObserver(forName:object:queue:using:) method rather than the addObserver(_:selector:name:object:) method that is often used from Objective-C code. The advantage of the first variant is that you don't have to use the @objc attribute on your method:

    func batteryLevelChanged(notification: Notification) {
        // do something useful with this information
    }

    let observer = NotificationCenter.default.addObserver(
        forName: NSNotification.Name.UIDeviceBatteryLevelDidChange,
        object: nil, queue: nil,
        using: batteryLevelChanged)

and you can even just use a closure instead of a method if you want:

    let observer = NotificationCenter.default.addObserver(
        forName: NSNotification.Name.UIDeviceBatteryLevelDidChange,
        object: nil, queue: nil) { _ in print("") }

You can use the returned value to stop listening for the notification later:

    NotificationCenter.default.removeObserver(observer)

There used to be another advantage in using this method, which was that it doesn't require you to use selector strings which couldn't be statically checked by the compiler and so were fragile to breaking if the method is renamed, but Swift 2.2 and later include #selector expressions that fix that problem.

Bit counter-intuitive, but you must first setup a SDK for Java projects. On the bottom right of the IntelliJ welcome screen, select 'Configure > Project Defaults > Project Structure'.

The Project tab on the left will show that you have no SDK selected:

Therefore, you must click the 'New...' button on the right hand side of the dropdown and point it to your JDK. After that, you can go back to the import screen and it should be populated with your JAVA_HOME variable, providing you have this set.

Use DATE_FORMAT function to change the format.

SELECT DATE_FORMAT(CURDATE(), '%d/%m/%Y')

SELECT DATE_FORMAT(column_name, '%d/%m/%Y') FROM tablename

Refer DOC for more details

"Segmentation fault" means that you tried to access memory that you do not have access to.

The first problem is with your arguments of main. The main function should be int main(int argc, char *argv[]), and you should check that argc is at least 2 before accessing argv[1].

Also, since you're passing in a float to printf (which, by the way, gets converted to a double when passing to printf), you should use the %f format specifier. The %s format specifier is for strings ('\0'-terminated character arrays).

The command setwd("~/") should set your working directory to your home directory. You might be experiencing problems because the OS you are using does not recognise "~/" as your home directory: this might be because of the OS, or it might be because of not having set that as your home directory elsewhere.

As you have tagged the post using RStudio:

• In the bottom right window move the tab over to 'files'.
• Navigate through there to whichever folder you were planning to use as your working directory.
• Under 'more' click 'set as working directory'

You will now have set the folder as your working directory. Use the command getwd() to get the working directory as it is now set, and save that as a variable string at the top of your script. Then use setwd with that string as the argument, so that each time you run the script you use the same directory.

For example at the top of my script I would have:

work_dir <- "C:/Users/john.smith/Documents"
setwd(work_dir)

string shortFoo = foo.Length > 5 ? foo.Substring(0, 5) : foo;

Note that you can't just use foo.Substring(0, 5) by itself because it will throw an error when foo is less than 5 characters.

I had the same issue and tried everything. This 400 happened for an upstream proxy. Debug logged showed absolutely nothing.

The problem was in duplicate proxy_set_header Host $http_host directive, which I didn't notice initially. Removing duplicate one solved the issue immediately. I wish nginx was saying something other than 400 in this scenario, as nginx -t didn't complain at all.

P.S. this happened while migrating from older nginx 1.10 to the newer 1.19. Before it was tolerated apparently.

For react-native users who don't use Xcode often, you can just use find. Open a terminal and search by with the database name.

$ find ~/Library/Developer -name 'myname.db'

If you don't know the exact name you can use wildcards:

$ find ~/Library/Developer -name 'myname.*'

Convert String to Int

var myInt = int.parse('12345');
assert(myInt is int);
print(myInt); // 12345
print(myInt.runtimeType);

Convert String to Double

var myDouble = double.parse('123.45');
assert(myInt is double);
print(myDouble); // 123.45
print(myDouble.runtimeType);

I once had an issue like this, when i downloadad a lib from Amazon (for Amazon webservices) and that jar file contained a log4j.properties and somehow that was used instead of my good old, self configed log4j. Worth a check.

I've added:

xcuserstate
xcsettings

and placed my .gitignore file at the root of my project.

After committing and pushing. I then ran:

git rm --cached UserInterfaceState.xcuserstate WorkspaceSettings.xcsettings

buried with the folder below:

<my_project_name>/<my_project_name>.xcodeproj/project.xcworkspace/xcuserdata/<my_user_name>.xcuserdatad/

I then ran git commit and push again

C# - serialData is ReceivedEventHandler in TextBox.

SerialPort sData = sender as SerialPort;
string recvData = sData.ReadLine();

serialData.Invoke(new Action(() => serialData.Text = String.Concat(recvData)));

Now Visual Studio drops my lines. TextBox, of course, had all the correct options on.

Serial:

Serial.print(rnd);
Serial.( '\n' );  //carriage return

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/> 

It's even easier to do without a library

window.onload = function() {
    // code
};

This can be easily done using the tags

The example of tags is defined below:

---
hosts: localhost
tasks:
 - name: Creating s3Bucket
   s3_bucket:
        name: ansiblebucket1234567890
   tags: 
       - createbucket

 - name: Simple PUT operation
   aws_s3:
       bucket: ansiblebucket1234567890
       object: /my/desired/key.txt
       src: /etc/ansible/myfile.txt
       mode: put
   tags:
      - putfile

 - name: Create an empty bucket
   aws_s3:
       bucket: ansiblebucket12345678901234
       mode: create
       permission: private
   tags:
       - emptybucket

to execute the tags we use the command

ansible-playbook creates3bucket.yml --tags "createbucket,putfile"

You can always run this:

java -cp HelloWorld.jar HelloWorld

-cp HelloWorld.jar adds the jar to the classpath, then HelloWorld runs the class you wrote.

To create a runnable jar with a main class with no package, add Class-Path: . to the manifest:

Manifest-Version: 1.0
Class-Path: .
Main-Class: HelloWorld

I would advise using a package to give your class its own namespace. E.g.

package com.stackoverflow.user.blrp;

public class HelloWorld {
    ...
}

late but maybe useful

When app is not running

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

is called ..

where u need to check for push notification

NSDictionary *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (notification) {
    NSLog(@"app recieved notification from remote%@",notification);
    [self application:application didReceiveRemoteNotification:notification];
} else {
    NSLog(@"app did not recieve notification");
}

Use compareTo:

date1.compareTo(date2);

You are not writing your code inside any function, you can return from functions only. Remove return statement and just print the value you want.

Worked for me. ^^

I’m using this:

<!-- language: c# -->
private static string wmiProperty(string wmiClass, string wmiProperty){
  using (var searcher = new ManagementObjectSearcher($"SELECT * FROM {wmiClass}")) {
   try {
                    IEnumerable<ManagementObject> objects = searcher.Get().Cast<ManagementObject>();
                    return objects.Select(x => x.GetPropertyValue(wmiProperty)).FirstOrDefault().ToString().Trim();
                } catch (NullReferenceException) {
                    return null;
                }
            }
        }

I have been having a lot of luck with jpg images taken with the same camera on a tripod by (1) simplifying greatly (like going from 3000 pixels wide to 100 pixels wide or even fewer) (2) flattening each jpg array into a single vector (3) pairwise correlating sequential images with a simple correlate algorithm to get correlation coefficient (4) squaring correlation coefficient to get r-square (i.e fraction of variability in one image explained by variation in the next) (5) generally in my application if r-square < 0.9, I say the two images are different and something happened in between.

This is robust and fast in my implementation (Mathematica 7)

It's worth playing around with the part of the image you are interested in and focussing on that by cropping all images to that little area, otherwise a distant-from-the-camera but important change will be missed.

I don't know how to use Python, but am sure it does correlations, too, no?

SET string=bath Abath Bbath XYZbathABC
SET modified=%string:bath=hello%
ECHO %string%
ECHO %modified%

EDIT

Didn't see at first that you wanted the replacement to be preceded by reading the string from a file.

Well, with a batch file you don't have much facility of working on files. In this particular case, you'd have to read a line, perform the replacement, then output the modified line, and then... What then? If you need to replace all the ocurrences of 'bath' in all the file, then you'll have to use a loop:

@ECHO OFF
SETLOCAL DISABLEDELAYEDEXPANSION
FOR /F %%L IN (file.txt) DO (
  SET "line=%%L"
  SETLOCAL ENABLEDELAYEDEXPANSION
  ECHO !line:bath=hello!
  ENDLOCAL
)
ENDLOCAL

You can add a redirection to a file:

  ECHO !line:bath=hello!>>file2.txt

Or you can apply the redirection to the batch file. It must be a different file.

EDIT 2

Added proper toggling of delayed expansion for correct processing of some characters that have special meaning with batch script syntax, like !, ^ et al. (Thanks, jeb!)

Do you really want the result to come up in an input box? If not, consider a table with borders set to other than transparent and use

document.getElementById('sum').innerHTML = sum;

For me the following worked on Jenkins 2.190.1 and was much simpler than some of the other workarounds:

matcher = manager.getLogMatcher('^.*Text we want comes next: (.*)$');

if (matcher.matches()) {
    def myVar = matcher.group(1);
    def envVar = new EnvVars([MY_ENV_VAR: myVar]);
    def newEnv = Environment.create(envVar);
    manager.build.environments.add(0, newEnv);
    // now the matched text from the LogMatcher is passed to an
    // env var we can access at $MY_ENV_VAR in post build steps
}

This was using the Groovy Script plugin with no additional changes to Jenkins.

OR condition in #ifdef

#if defined LINUX || defined ANDROID
// your code here
#endif /* LINUX || ANDROID */

or-

#if defined(LINUX) || defined(ANDROID)
// your code here
#endif /* LINUX || ANDROID */

Both above are the same, which one you use simply depends on your taste.

P.S.: #ifdef is simply the short form of #if defined, however, does not support complex condition.

Further-

• AND: #if defined LINUX && defined ANDROID
• XOR: #if defined LINUX ^ defined ANDROID

There is no way to create a file without opening it There is os.mknod("newfile.txt") (but it requires root privileges on OSX). The system call to create a file is actually open() with the O_CREAT flag. So no matter how, you'll always open the file.

So the easiest way to simply create a file without truncating it in case it exists is this:

open(x, 'a').close()

Actually you could omit the .close() since the refcounting GC of CPython will close it immediately after the open() statement finished - but it's cleaner to do it explicitely and relying on CPython-specific behaviour is not good either.

In case you want touch's behaviour (i.e. update the mtime in case the file exists):

import os
def touch(path):
    with open(path, 'a'):
        os.utime(path, None)

You could extend this to also create any directories in the path that do not exist:

basedir = os.path.dirname(path)
if not os.path.exists(basedir):
    os.makedirs(basedir)

Try hovering with the mouse over the underlined elements. It should normally tell you what the problem. To see a list of all the errors/warnings, go to View => Error List. A table should open on the bottom of the IDE with all the errors/warnings listed.

If you don't want to use float, the easiest and cleanest way to do it is by using an auto width column:

<div class="row">
  <div class="col">
    <h3 class="one">Text</h3>
  </div>
  <div class="col-auto">
    <button class="btn btn-secondary pull-right">Button</button>
  </div>
</div>

A nested object (child) inside another object (parent) cannot get data directly from its parent.

Have a look on this:

var main = {
    name : "main object",
    child : {
        name : "child object"
    }
};

If you ask the main object what its child name is (main.child.name) you will get it.
Instead you cannot do it vice versa because the child doesn't know who its parent is.
(You can get main.name but you won't get main.child.parent.name).

By the way, a function could be useful to solve this clue.
Let's extend the code above:

var main = {
    name : "main object",
    child : {
        name : "child object"
    },
    init : function() {
        this.child.parent = this;
        delete this.init;
        return this;
    }
}.init();

Inside the init function you can get the parent object simply calling this.
So we define the parent property directly inside the child object.
Then (optionally) we can remove the init method.
Finally we give the main object back as output from the init function.

If you try to get main.child.parent.name now you will get it right.
It is a little bit tricky but it works fine.

There are no optional parameters in Java. What you can do is overloading the functions and then passing default values.

void SomeMethod(int age, String name) {
    //
}

// Overload
void SomeMethod(int age) {
    SomeMethod(age, "John Doe");
}

I think I see your problem, you need to use the @ syntax to define parameters you will pass in this way, also I'm not sure what loginID or password are doing you don't seem to define them anywhere and they are not being used as URL parameters so are they being sent as query parameters?

This is what I can suggest based on what I see so far:

.factory('MagComments', function ($resource) {
    return $resource('http://localhost/dooleystand/ci/api/magCommenct/:id', {
      loginID : organEntity,
      password : organCommpassword,
      id : '@magId'
    });
  })

The @magId string will tell the resource to replace :id with the property magId on the object you pass it as parameters.

I'd suggest reading over the documentation here (I know it's a bit opaque) very carefully and looking at the examples towards the end, this should help a lot.

For all struggling around with the #selector in Swift 3 or Swift 4, here a full code example:

// WE NEED A CLASS THAT SHOULD RECEIVE NOTIFICATIONS
    class MyReceivingClass {

    // ---------------------------------------------
    // INIT -> GOOD PLACE FOR REGISTERING
    // ---------------------------------------------
    init() {
        // WE REGISTER FOR SYSTEM NOTIFICATION (APP WILL RESIGN ACTIVE)

        // Register without parameter
        NotificationCenter.default.addObserver(self, selector: #selector(MyReceivingClass.handleNotification), name: .UIApplicationWillResignActive, object: nil)

        // Register WITH parameter
        NotificationCenter.default.addObserver(self, selector: #selector(MyReceivingClass.handle(withNotification:)), name: .UIApplicationWillResignActive, object: nil)
    }

    // ---------------------------------------------
    // DE-INIT -> LAST OPTION FOR RE-REGISTERING
    // ---------------------------------------------
    deinit {
        NotificationCenter.default.removeObserver(self)
    }

    // either "MyReceivingClass" must be a subclass of NSObject OR selector-methods MUST BE signed with '@objc'

    // ---------------------------------------------
    // HANDLE NOTIFICATION WITHOUT PARAMETER
    // ---------------------------------------------
    @objc func handleNotification() {
        print("RECEIVED ANY NOTIFICATION")
    }

    // ---------------------------------------------
    // HANDLE NOTIFICATION WITH PARAMETER
    // ---------------------------------------------
    @objc func handle(withNotification notification : NSNotification) {
        print("RECEIVED SPECIFIC NOTIFICATION: \(notification)")
    }
}

In this example we try to get POSTs from AppDelegate (so in AppDelegate implement this):

// ---------------------------------------------
// WHEN APP IS GOING TO BE INACTIVE
// ---------------------------------------------
func applicationWillResignActive(_ application: UIApplication) {

    print("POSTING")

    // Define identifiyer
    let notificationName = Notification.Name.UIApplicationWillResignActive

    // Post notification
    NotificationCenter.default.post(name: notificationName, object: nil)
}

Simply use $('.myclass1, .myclass2, .myclass3') for multiple selectors. Also, you dont need lambda functions to bind an existing function to the click event.

Try this:

<add name="Access-Control-Allow-Origin" value="['URL1','URL2',...]" />

I had a simpler solution. Using @apple way but rename main.py to pip.py then put it in your python version scripts folder and add scripts folder to your path access it globally. if you don't want to add it to path you have to cd to scripts and then run pip command.

Don't try this, totally un-recommend, don't do this:

import string
s='ABCD'
print(''.join([string.ascii_lowercase[string.ascii_uppercase.index(i)] for i in s]))

Output:

abcd

Since no one wrote it yet you can use swapcase (so uppercase letters will become lowercase, and vice versa) (and this one you should use in cases where i just mentioned (convert upper to lower, lower to upper)):

s='ABCD'
print(s.swapcase())

Output:

abcd

You add html invisible layer over the form. For instance

<div class="coverContainer">
<form></form>
</div>

and style:

.coverContainer{
    width: 100%;
    height: 100%;
    z-index: 100;
    background: rgba(0,0,0,0);
    position: absolute;
}

Ofcourse user can hide this layer in web browser.

Actually, this is the proper way to get what you want, unless you can use MS SQL 2014 (which finally enables custom format strings for date times).

To get yyyymm instead of yyyym, you can use this little trick:

select 
 right('0000' + cast(datepart(year, getdate()) as varchar(4)), 4)
 + right('00' + cast(datepart(month, getdate()) as varchar(2)), 2)

It's faster and more reliable than gettings parts of convert(..., 112).

Arrays.fill(arrayName,value);

in java

int arrnum[] ={5,6,9,2,10};
for(int i=0;i<arrnum.length;i++){
  System.out.println(arrnum[i]+" ");
}
Arrays.fill(arrnum,0);
for(int i=0;i<arrnum.length;i++){
  System.out.println(arrnum[i]+" ");
}

Output

5 6 9 2 10
0 0 0 0 0

Wrap the code within $(document).ready(function(){...........}); handler , also remove the ; after if

$(document).ready(function(){
    $('#purpose').on('change', function() {
      if ( this.value == '1')
      //.....................^.......
      {
        $("#business").show();
      }
      else
      {
        $("#business").hide();
      }
    });
});

I still believe this is a fundamental / functional flaw brought about by a technicality. If you have an optional field by which you can identify a customer you now have to hack a dummy value into it, just because NULL != NULL, not particularly elegant yet it is an "industry standard"

List<V> choices; // your list
Map<K,V> result = choices.stream().collect(Collectors.toMap(choice::getKey(),choice));
//assuming class "V" has a method to get the key, this method must handle case of duplicates too and provide a unique key.

This answer uses promises, a JavaScript feature of the ECMAScript 6 standard. If your target platform does not support promises, polyfill it with PromiseJs.

Look at my answer here Wait till a Function with animations is finished until running another Function if you want to use jQuery animations.

Here is what your code would look like with ES6 Promises and jQuery animations.

Promise.resolve($('#art1').animate({ 'width': '1000px' }, 1000).promise()).then(function(){
    return Promise.resolve($('#art2').animate({ 'width': '1000px' }, 1000).promise());
}).then(function(){
    return Promise.resolve($('#art3').animate({ 'width': '1000px' }, 1000).promise());
});

Normal methods can also be wrapped in Promises.

new Promise(function(fulfill, reject){
    //do something for 5 seconds
    fulfill(result);
}).then(function(result){
    return new Promise(function(fulfill, reject){
        //do something for 5 seconds
        fulfill(result);
    });
}).then(function(result){
    return new Promise(function(fulfill, reject){
        //do something for 8 seconds
        fulfill(result);
    });
}).then(function(result){
    //do something with the result
});

The then method is executed as soon as the Promise finished. Normally, the return value of the function passed to then is passed to the next one as result.

But if a Promise is returned, the next then function waits until the Promise finished executing and receives the results of it (the value that is passed to fulfill).

When a thread object goes out of scope and it is in joinable state, the program is terminated. The Standard Committee had two other options for the destructor of a joinable thread. It could quietly join -- but join might never return if the thread is stuck. Or it could detach the thread (a detached thread is not joinable). However, detached threads are very tricky, since they might survive till the end of the program and mess up the release of resources. So if you don't want to terminate your program, make sure you join (or detach) every thread.

The duplicate values in any column can be deleted with a simple for loop.

Sub remove()
Dim a As Long
For a = Cells(Rows.Count, 1).End(xlUp).Row To 1 Step -1
If WorksheetFunction.CountIf(Range("A1:A" & a), Cells(a, 1)) > 1 Then Rows(a).Delete
Next
End Sub

This work for me in Angular 9:

  import {GoogleMap, GoogleMapsModule} from "@angular/google-maps";
  @ViewChild('Map') Map: GoogleMap; /* Element Map */

  locations = [
   { lat: 7.423568, lng: 80.462287 },
   { lat: 7.532321, lng: 81.021187 },
   { lat: 6.117010, lng: 80.126269 }
  ];

  constructor() {
   var bounds = new google.maps.LatLngBounds();
    setTimeout(() => {
     for (let u in this.locations) {
      var marker = new google.maps.Marker({
       position: new google.maps.LatLng(this.locations[u].lat, 
       this.locations[u].lng),
      });
      bounds.extend(marker.getPosition());
     }

     this.Map.fitBounds(bounds)
    }, 200)
  }

And it automatically centers the map according to the indicated positions.

Result:

In my case, I've lost all private keys in my keychain, new ones were imported correctly, but doesn't show the private key as well. The only thing that helped was generating new CertificateSigningRequest

You can read it from the input stream:

public ActionResult ManagePhotos(ManagePhotos model)
{
    if (ModelState.IsValid)
    {
        byte[] image = new byte[model.File.ContentLength];
        model.File.InputStream.Read(image, 0, image.Length); 

        // TODO: Do something with the byte array here
    }
    ...
}

And if you intend to directly save the file to the disk you could use the model.File.SaveAs method. You might find the following blog post useful.

Sadly I can't answer the other questions, don't have enough reputation, but I need to point something out that was VERY important for me, and I think it will help other people too.

Unsetting the variable is a nice way, unless you need the reference of the original array!

To make clear what I mean: If you have a function wich uses the reference of the array, for example a sorting function like

function special_sort_my_array(&$array)
{
    $temporary_list = create_assoziative_special_list_out_of_array($array);

    sort_my_list($temporary_list);

    unset($array);
    foreach($temporary_list as $k => $v)
    {
        $array[$k] = $v;
    }
}

it is not working! Be careful here, unset deletes the reference, so the variable $array is created again and filled correctly, but the values are not accessable from outside the function.

So if you have references, you need to use $array = array() instead of unset, even if it is less clean and understandable.

I created a project to easily initiate a project skeleton from scratch. https://github.com/MacHu-GWU/pygitrepo-project.

And you can create a test project, let's say, learn_creating_py_package.

You can learn what component you should have for different purpose like:

• create virtualenv
• install itself
• run unittest
• run code coverage
• build document
• deploy document
• run unittest in different python version
• deploy to PYPI

The advantage of using pygitrepo is that those tedious are automatically created itself and adapt your package_name, project_name, github_account, document host service, windows or macos or linux.

It is a good place to learn develop a python project like a pro.

Hope this could help.

Thank you.

For MS T-SQL Server, I suggest looking into creating an index with the "include" statement. Uniqueness is not required, neither is the physical sorting of data associated with a clustered index. The "Index ... Include ()" creates a separate physical data storage automatically maintained by the system. It is conceptually very similar to an Oracle Materialized View.

Sometimes, a Swift version of the "SQLite in 5 minutes or less" approach shown on sqlite.org is sufficient. The "5 minutes or less" approach uses sqlite3_exec() which is a convenience wrapper for sqlite3_prepare(), sqlite3_step(), sqlite3_column(), and sqlite3_finalize().

Swift 2.2 can directly support the sqlite3_exec() callback function pointer as either a global, non-instance procedure func or a non-capturing literal closure {}.

Readable typealias

typealias sqlite3 = COpaquePointer
typealias CCharHandle = UnsafeMutablePointer<UnsafeMutablePointer<CChar>>
typealias CCharPointer = UnsafeMutablePointer<CChar>
typealias CVoidPointer = UnsafeMutablePointer<Void>

Callback Approach

func callback(
    resultVoidPointer: CVoidPointer, // void *NotUsed 
    columnCount: CInt,               // int argc
    values: CCharHandle,             // char **argv     
    columns: CCharHandle             // char **azColName
    ) -> CInt {
    for  i in 0 ..< Int(columnCount) {
        guard let value = String.fromCString(values[i]) 
        else { continue }
        guard let column = String.fromCString(columns[i]) 
        else { continue }
        print("\(column) = \(value)")
    }
    return 0 // status ok
}

    }

    rc = sqlite3_open(argv[1], &db)
    if  rc != 0 {
        print("ERROR: sqlite3_open " + String.fromCString(sqlite3_errmsg(db))! ?? "" )
        sqlite3_close(db)

    rc = sqlite3_exec(db, argv[2], callback, nil, &zErrMsg)
    if rc != SQLITE_OK {

        sqlite3_free(zErrMsg)
    }

    sqlite3_close(db)

Closure Approach

func sqlQueryClosureBasic(argc argc: Int, argv: [String]) -> Int {
    var db: sqlite3 = nil 
    var zErrMsg:CCharPointer = nil
    var rc: Int32 = 0

    if argc != 3 {

    }

    rc = sqlite3_exec(
        db,      // database 
        argv[2], // statement
        {        // callback: non-capturing closure

To prepare an Xcode project to call a C library such as SQLite, one needs to (1) add a Bridging-Header.h file reference C headers like #import "sqlite3.h", (2) add Bridging-Header.h to Objective-C Bridging Header in project settings, and (3) add libsqlite3.tbd to Link Binary With Library target settings.

The sqlite.org's "SQLite in 5 minutes or less" example is implemented in a Swift Xcode7 project here.

Fastest way I found is via inner1d. Here's how it compares to other numpy methods:

import numpy as np
from numpy.core.umath_tests import inner1d

V = np.random.random_sample((10**6,3,)) # 1 million vectors
A = np.sqrt(np.einsum('...i,...i', V, V))
B = np.linalg.norm(V,axis=1)   
C = np.sqrt((V ** 2).sum(-1))
D = np.sqrt((V*V).sum(axis=1))
E = np.sqrt(inner1d(V,V))

print [np.allclose(E,x) for x in [A,B,C,D]] # [True, True, True, True]

import cProfile
cProfile.run("np.sqrt(np.einsum('...i,...i', V, V))") # 3 function calls in 0.013 seconds
cProfile.run('np.linalg.norm(V,axis=1)')              # 9 function calls in 0.029 seconds
cProfile.run('np.sqrt((V ** 2).sum(-1))')             # 5 function calls in 0.028 seconds
cProfile.run('np.sqrt((V*V).sum(axis=1))')            # 5 function calls in 0.027 seconds
cProfile.run('np.sqrt(inner1d(V,V))')                 # 2 function calls in 0.009 seconds

inner1d is ~3x faster than linalg.norm and a hair faster than einsum

Combining the answer from @egis and others - this works well on a variety of devices, tested on Pixel EMU, Samsung S6, Sony Z3, Nexus 4. This code uses the display dimensions to test for availability of nav bar and then uses the actual system nav bar size if present.

For those like me who were looking for an ellipse attributes to path conversion:

const ellipseAttrsToPath = (rx,cx,ry,cy) =>
`M${cx-rx},${cy}a${rx},${ry} 0 1,0 ${rx*2},0a${rx},${ry} 0 1,0 -${rx*2},0`

I'd like to point out that one issues is what if the same resources are in multiple jar files. Let's say you want to read /org/node/foo.txt, but not from one file, but from each and every jar file.

I have run into this same issue several times before. I was hoping in JDK 7 that someone would write a classpath filesystem, but alas not yet.

Spring has the Resource class which allows you to load classpath resources quite nicely.

I wrote a little prototype to solve this very problem of reading resources form multiple jar files. The prototype does not handle every edge case, but it does handle looking for resources in directories that are in the jar files.

I have used Stack Overflow for quite sometime. This is the second answer that I remember answering a question so forgive me if I go too long (it is my nature).

This is a prototype resource reader. The prototype is devoid of robust error checking.

I have two prototype jar files that I have setup.

 <pre>
         <dependency>
              <groupId>invoke</groupId>
              <artifactId>invoke</artifactId>
              <version>1.0-SNAPSHOT</version>
          </dependency>

          <dependency>
               <groupId>node</groupId>
               <artifactId>node</artifactId>
               <version>1.0-SNAPSHOT</version>
          </dependency>

The jar files each have a file under /org/node/ called resource.txt.

This is just a prototype of what a handler would look like with classpath:// I also have a resource.foo.txt in my local resources for this project.

It picks them all up and prints them out.

   

    package com.foo;

    import java.io.File;
    import java.io.FileReader;

This is how I organized my application's static resources.

The path you give to LOAD DATA INFILE is for the filesystem on the machine where the server is running, not the machine you connect from. LOAD DATA LOCAL INFILE is for the client's machine, but it requires that the server was started with the right settings, otherwise it's not allowed. You can read all about it here: http://dev.mysql.com/doc/refman/5.0/en/load-data-local.html

As for SELECT INTO OUTFILE I'm not sure why there is not a local version, besides it probably being tricky to do over the connection. You can get the same functionality through the mysqldump tool, but not through sending SQL to the server.

If the place you're gonna paste have no problem with pasting a table formating (like the browser URL bar), I think the easiest way is this:

Sheets(1).Range("A1000").Value = string
Sheets(1).Range("A1000").Copy
MsgBox "Paste before closing this dialog."
Sheets(1).Range("A1000").Value = ""

You can use the ID field as the equality identifier. You can't use the adhoc object for this case because AngularJS checks references equality when comparing objects.

<select 
    ng-model="Choice.SelectedOption.ID" 
    ng-options="choice.ID as choice.Name for choice in Choice.Options">
</select>

To work in objective-c I have to put the following lines in viewWillAppear in my CustomViewController.

[self.navigationController.navigationBar setBarTintColor:[UIColor whiteColor]];
[self.navigationController.navigationBar setTranslucent:NO];

For Swift2.x this works:

self.navigationController?.navigationBar.barTintColor = UIColor.redColor()

For Swift3.x this works:

self.navigationController?.navigationBar.barTintColor = UIColor.red

I had this problem and the suggestions above didn't help. What I found is that the add-migration reads the current state and creates a signature of the current model. You must modify your model before modifying. So the sequence is.

1. Modify model
2. run add-migration

I did the opposite and added the migration before modifying my model (which was empty, so I added the new columns) and then ran my code.

Hope this helps.

If you want to pursue a "simple" solution, you might find this class I put together useful:

http://www.architectshack.com/TextFileEncodingDetector.ashx

It does the BOM detection automatically first, and then tries to differentiate between Unicode encodings without BOM, vs some other default encoding (generally Windows-1252, incorrectly labelled as Encoding.ASCII in .Net).

As noted above, a "heavier" solution involving NCharDet or MLang may be more appropriate, and as I note on the overview page of this class, the best is to provide some form of interactivity with the user if at all possible, because there simply is no 100% detection rate possible!

        /*
         * Simple class to handle text file encoding woes (in a primarily English-speaking tech 
         *      world).
         * 
         *  - This code is fully managed, no shady calls to MLang (the unmanaged codepage
         *      detection library originally developed for Internet Explorer).
         * 
         *  - This class does NOT try to detect arbitrary codepages/charsets, it really only
         *      aims to differentiate between some of the most common variants of Unicode 
         *      encoding, and a "default" (western / ascii-based) encoding alternative provided
         *      by the caller.
         *      
         *  - As there is no "Reliable" way to distinguish between UTF-8 (without BOM) and 
         *      Windows-1252 (in .Net, also incorrectly called "ASCII") encodings, we use a 
         *      heuristic - so the more of the file we can sample the better the guess. If you 
         *      are going to read the whole file into memory at some point, then best to pass 
         *      in the whole byte byte array directly. Otherwise, decide how to trade off 
         *      reliability against performance / memory usage.
         *      
         *  - The UTF-8 detection heuristic only works for western text, as it relies on 
         *      the presence of UTF-8 encoded accented and other characters found in the upper 
         *      ranges of the Latin-1 and (particularly) Windows-1252 codepages.
         *  
         *  - For more general detection routines, see existing projects / resources:
         *    - MLang - Microsoft library originally for IE6, available in Windows XP and later APIs now (I think?)
         *      - MLang .Net bindings: http://www.codeproject.com/KB/recipes/DetectEncoding.aspx
         *    - CharDet - Mozilla browser's detection routines
         *      - Ported to Java then .Net: http://www.conceptdevelopment.net/Localization/NCharDet/
         *      - Ported straight to .Net: http://code.google.com/p/chardetsharp/source/browse

Ahhh, the stupid linesize ... Here is what I do in my profile.sql - works only on unixes:

Edit 7/17/2020: I cannot delete this accepted answer. It used to be good, but now it isn't. Beware really old posts, guys. I'm removing the link.

[Linqer] is a SQL to LINQ converter tool. It helps you to learn LINQ and convert your existing SQL statements.

Not every SQL statement can be converted to LINQ, but Linqer covers many different types of SQL expressions. Linqer supports both .NET languages - C# and Visual Basic.

See also: How to properly override clone method?. Cloning is broken in Java, it's so hard to get it right, and even when it does it doesn't really offer much, so it's not really worth the hassle.

Use a JSON library to parse the string and retrieve the value.

The following very basic example uses the built-in JSON parser from Android.

String jsonString = "{ \"name\" : \"John\", \"age\" : \"20\", \"address\" : \"some address\" }";
JSONObject jsonObject = new JSONObject(jsonString);
int age = jsonObject.getInt("age");

More advanced JSON libraries, such as jackson, google-gson, json-io or genson, allow you to convert JSON objects to Java objects directly.

I just replicate the 2 attributes of the btn-navbar (data-toggle="collapse" data-target=".nav-collapse.in") on each link like this:

<div class="nav-collapse">
  <ul class="nav" >
    <li class="active"><a href="#home" data-toggle="collapse" data-target=".nav-collapse.in">Home</a></li>
    <li><a href="#about" data-toggle="collapse" data-target=".nav-collapse.in">About</a></li>
    <li><a href="#portfolio" data-toggle="collapse" data-target=".nav-collapse.in">Portfolio</a></li>
    <li><a href="#services" data-toggle="collapse" data-target=".nav-collapse.in">Services</a></li>
    <li><a href="#contact" data-toggle="collapse" data-target=".nav-collapse.in">Contact</a></li>
  </ul>
</div>

In the Bootstrap 4 Navbar, in has changed to show so the syntax would be:

data-toggle="collapse" data-target=".navbar-collapse.show"

for me with bootstrap 4 datetime picker (http://www.eyecon.ro/bootstrap-datepicker/) format worked only with upper case:

$('.datepicker').datetimepicker({
            format: 'DD/MM/YYYY'
        });

You have three options:

• either you are calculating the attribute using a @Transient method
• you can also use @PostLoad entity listener
• or you can use the Hibernate specific @Formula annotation

While Hibernate allows you to use @Formula, with JPA, you can use the @PostLoad callback to populate a transient property with the result of some calculation:

@Column(name = "price")
private Double price;

@Column(name = "tax_percentage")
private Double taxes;

@Transient
private Double priceWithTaxes;

@PostLoad
private void onLoad() {
    this.priceWithTaxes = price * taxes;
}

So, you can use the Hibernate @Formula like this:

@Formula("""
    round(
       (interestRate::numeric / 100) *
       cents *
       date_part('month', age(now(), createdOn)
    )
    / 12)
    / 100::numeric
    """)
private double interestDollars;

platform.js seems like a good one file library to do this.

Usage example:

// on IE10 x86 platform preview running in IE7 compatibility mode on Windows 7 64 bit edition
platform.name; // 'IE'
platform.version; // '10.0'
platform.layout; // 'Trident'
platform.os; // 'Windows Server 2008 R2 / 7 x64'
platform.description; // 'IE 10.0 x86 (platform preview; running in IE 7 mode) on Windows Server 2008 R2 / 7 x64'

// or on an iPad
platform.name; // 'Safari'
platform.version; // '5.1'
platform.product; // 'iPad'
platform.manufacturer; // 'Apple'
platform.layout; // 'WebKit'
platform.os; // 'iOS 5.0'
platform.description; // 'Safari 5.1 on Apple iPad (iOS 5.0)'

// or parsing a given UA string
var info = platform.parse('Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7.2; en; rv:2.0) Gecko/20100101 Firefox/4.0 Opera 11.52');
info.name; // 'Opera'
info.version; // '11.52'
info.layout; // 'Presto'
info.os; // 'Mac OS X 10.7.2'
info.description; // 'Opera 11.52 (identifying as Firefox 4.0) on Mac OS X 10.7.2'

You can try 'onbeforeunload' event.

I've also implemented a robust, open source, easy to use and highly customizable PullToRefresh library for Android. You can replace your ListView with the PullToRefreshListView as described in the documentation on the project page.

a) When a cdecl function is called by the caller, how does a caller know if it should free up the stack?

The cdecl modifier is part of the function prototype (or function pointer type etc.) so the caller get the info from there and acts accordingly.

b) If a function which is declared as stdcall calls a function(which has a calling convention as cdecl), or the other way round, would this be inappropriate?

No, it's fine.

c) In general, can we say that which call will be faster - cdecl or stdcall?

In general, I would refrain from any such statements. The distinction matters eg. when you want to use va_arg functions. In theory, it could be that stdcall is faster and generates smaller code because it allows to combine popping the arguments with popping the locals, but OTOH with cdecl, you can do the same thing, too, if you're clever.

The calling conventions that aim to be faster usually do some register-passing.

Try PowerPoint ActiveX 2.4. This is an ActiveX component that embeds PowerPoint into an OCX.

Since you are using just Internet Explorer 6 and Internet Explorer 7 you can embed this component into the HTML.

Use numeric values instead of strings.

Finally to convert the constants JACK or QUEEN to a string, use the stringize (and/or tokenize) operators.

To summarize, we have three approaches to accomplish this:

1. Set an environment variable named "PORT"
2. Modify the "start" key under "scripts" part of package.json
3. Create a .env file and put the PORT configuration in it

The most portable one will be the last approach. But as mentioned by other poster, add .env into .gitignore in order not to upload the configuration to the public source repository.

You can use MySQL JSON datatype to store the array

mysql> CREATE TABLE t1 (jdoc JSON);

Query OK, 0 rows affected (0.20 sec)

mysql> INSERT INTO t1 VALUES('{"key1": "value1", "key2": "value2"}');

Query OK, 1 row affected (0.01 sec)

To get the above object in PHP

json_encode(["key1"=> "value1", "key2"=> "value2"]);

More in https://dev.mysql.com/doc/refman/8.0/en/json.html

Note that if you have a generic interface IMyInterface<T> then this will always return false:

  typeof(IMyInterface<>).IsAssignableFrom(typeof(MyType)) /* ALWAYS FALSE */

This doesn't work either:

  typeof(MyType).GetInterfaces().Contains(typeof(IMyInterface<>))  /* ALWAYS FALSE */

However, if MyType implements IMyInterface<MyType> this works and returns true:

  typeof(IMyInterface<MyType>).IsAssignableFrom(typeof(MyType))

However, you likely will not know the type parameter T at runtime. A somewhat hacky solution is:

  typeof(MyType).GetInterfaces()
                .Any(x=>x.Name == typeof(IMyInterface<>).Name)

Jeff's solution is a bit less hacky:

  typeof(MyType).GetInterfaces()
         .Any(i => i.IsGenericType 
             && i.GetGenericTypeDefinition() == typeof(IMyInterface<>));

Here's a extension method on Type that works for any case:

public static class TypeExtensions
{
    public static bool IsImplementing(this Type type, Type someInterface)
    {
        return type.GetInterfaces()
             .Any(i => i == someInterface 
                 || i.IsGenericType 
                    && i.GetGenericTypeDefinition() == someInterface);
    }
}

(Note that the above uses linq, which is probably slower than a loop.)

You can then do:

   typeof(MyType).IsImplementing(IMyInterface<>)

Based on @lijat, here is a simplified implementation. In my spring-based application I simply load this as a bean.

public static void configureLog4jFromSystemProperties()
{
  final String LOGGER_PREFIX = "log4j.logger.";

  for(String propertyName : System.getProperties().stringPropertyNames())
  {
    if (propertyName.startsWith(LOGGER_PREFIX)) {
      String loggerName = propertyName.substring(LOGGER_PREFIX.length());
      String levelName = System.getProperty(propertyName, "");
      Level level = Level.toLevel(levelName); // defaults to DEBUG
      if (!"".equals(levelName) && !levelName.toUpperCase().equals(level.toString())) {
        logger.error("Skipping unrecognized log4j log level " + levelName + ": -D" + propertyName + "=" + levelName);
        continue;
      }
      logger.info("Setting " + loggerName + " => " + level.toString());
      Logger.getLogger(loggerName).setLevel(level);
    }
  }
}

The new pathlib library simplifies this to one line:

from pathlib import Path
result = list(Path(PATH).glob('**/*.txt'))

You can also use the generator version:

from pathlib import Path
for file in Path(PATH).glob('**/*.txt'):
    pass

This returns Path objects, which you can use for pretty much anything, or get the file name as a string by file.name.

For make a list, simply do that

colors=(red orange white "light gray")

Technically is an array, but - of course - it has all list features.
Even python list are implemented with array

According to the documentation:

When should I use an attribute versus an element? Use an element when you are creating a component that is in control of the template. The common case for this is when you are creating a Domain-Specific Language for parts of your template. Use an attribute when you are decorating an existing element with new functionality.

Edit following comment on pitfalls for a complete answer:

Assuming you're building an app that should run on Internet Explorer <= 8, whom support has been dropped by AngularJS team from AngularJS 1.3, you have to follow the following instructions in order to make it working: https://docs.angularjs.org/guide/ie

Yes, it's intended to be checked in. I want to suggest that it gets its own unique commit. We find that it adds a lot of noise to our diffs.

I'm not sure that you want to send two SELECT statements in one request statement because you may not be able to access both ResultSets. The database may only return the last result set.

Multiple ResultSets

However, if you're calling a stored procedure that you know can return multiple resultsets something like this will work

CallableStatement stmt = con.prepareCall(...);
try {
...

boolean results = stmt.execute();

while (results) {
    ResultSet rs = stmt.getResultSet();
    try {
    while (rs.next()) {
        // read the data
    }
    } finally {
        try { rs.close(); } catch (Throwable ignore) {}
    }

    // are there anymore result sets?
    results = stmt.getMoreResults();
}
} finally {
    try { stmt.close(); } catch (Throwable ignore) {}
}

Multiple SQL Statements

If you're talking about multiple SQL statements and only one SELECT then your database should be able to support the one String of SQL. For example I have used something like this on Sybase

StringBuffer sql = new StringBuffer( "SET rowcount 100" );
sql.append( " SELECT * FROM tbl_books ..." );
sql.append( " SET rowcount 0" );

stmt = conn.prepareStatement( sql.toString() );

This will depend on the syntax supported by your database. In this example note the addtional spaces padding the statements so that there is white space between the staments.

For all you non-xml config folks:

ObjectMapper objMapper = new ObjectMapper().setSerializationInclusion(JsonInclude.Include.NON_NULL);
HttpMessageConverter msgConverter = new MappingJackson2HttpMessageConverter(objMapper);
restTemplate.setMessageConverters(Collections.singletonList(msgConverter));

Answering old thread here (and a bit off-topic) because it's what I found when I was searching how to install Image Magick on Mac OS to run on the local webserver. It's not enough to brew install Imagemagick. You have to also PECL install it so the PHP module is loaded.

From this SO answer:

brew install php
brew install imagemagick
brew install pkg-config
pecl install imagick

And you may need to sudo apachectl restart. Then check your phpinfo() within a simple php script running on your web server.

If it's still not there, you probably have an issue with running multiple versions of PHP on the same Mac (one through the command line, one through your web server). It's beyond the scope of this answer to resolve that issue, but there are some good options out there.

How come no-one seems to like repr?
python 3.7.2:

>>> int_list = [1, 2, 3, 4, 5]
>>> print(repr(int_list))
[1, 2, 3, 4, 5]
>>> 

Take care though, it's an explicit representation. An example shows:

#Print repr(object) backwards
>>> print(repr(int_list)[::-1])
]5 ,4 ,3 ,2 ,1[
>>>

Python includes a function called itemgetter to return the item at a specific index in a list:

from operator import itemgetter

Pass the itemgetter() function the index of the item you want to retrieve. To retrieve the first item, you would use itemgetter(0). The important thing to understand is that itemgetter(0) itself returns a function. If you pass a list to that function, you get the specific item:

itemgetter(0)([10, 20, 30]) # Returns 10

This is useful when you combine it with map(), which takes a function as its first argument, and a list (or any other iterable) as the second argument. It returns the result of calling the function on each object in the iterable:

my_list = [['a', 'b', 'c'], [1, 2, 3], ['x', 'y', 'z']]
list(map(itemgetter(0), my_list)) # Returns ['a', 1, 'x']

Note that map() returns a generator, so the result is passed to list() to get an actual list. In summary, your task could be done like this:

lst2.append(list(map(itemgetter(0), lst)))

This is an alternative method to using a list comprehension, and which method to choose highly depends on context, readability, and preference.

You're probably trying to run Python 3 file with Python 2 interpreter. Currently (as of 2019), python command defaults to Python 2 when both versions are installed, on Windows and most Linux distributions.

But in case you're indeed working on a Python 2 script, a not yet mentioned on this page solution is to resave the file in UTF-8+BOM encoding, that will add three special bytes to the start of the file, they will explicitly inform the Python interpreter (and your text editor) about the file encoding.

Perhaps you need a selected range in addition to cursor position. Here is a simple function, you don't even need jQuery:

function caretPosition(input) {
    var start = input[0].selectionStart,
        end = input[0].selectionEnd,
        diff = end - start;

    if (start >= 0 && start == end) {
        // do cursor position actions, example:
        console.log('Cursor Position: ' + start);
    } else if (start >= 0) {
        // do ranged select actions, example:
        console.log('Cursor Position: ' + start + ' to ' + end + ' (' + diff + ' selected chars)');
    }
}

Let's say you wanna call it on an input whenever it changes or mouse moves cursor position (in this case we are using jQuery .on()). For performance reasons, it may be a good idea to add setTimeout() or something like Underscores _debounce() if events are pouring in:

$('input[type="text"]').on('keyup mouseup mouseleave', function() {
    caretPosition($(this));
});

Here is a fiddle if you wanna try it out: https://jsfiddle.net/Dhaupin/91189tq7/

I recommend status code 422, "Unprocessable Entity".

11.2. 422 Unprocessable Entity

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

Go to /etc/php5/fpm/pool.d/www.conf and if you are using sockets or this line is uncommented

listen = /var/run/php5-fpm.sock

Set couple of other values too:-

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

Don't forget to restart php-fpm and nginx. Make sure you are using the same nginx owner and group name.

Noticed this was never resolved... You likely have a firewall in front of your machine blocking those ports, or iptables is set up to prevent the use of those ports.

Try running nmap -F localhost when you run your app (install nmap if you don't have it). If it appears that you're running the app on the correct port and you can't access it via a remote browser then there is some middleware or a physical firewall that's blocking the port.

Hope this helps!

Here is a code that should work in both Python 2.x and 3.x

Obviously you will need the six module, but it's almost impossible to write modules that work in both versions without six.

try:

Great answers. Adding one that loads the color from an Android resources xml but still sets it programmatically:

textView.setTextColor(getResources().getColor(R.color.some_color));

Please note that from API 23, getResources().getColor() is deprecated. Use instead:

textView.setTextColor(ContextCompat.getColor(context, R.color.some_color));

where the required color is defined in an xml as:

<resources>
  <color name="some_color">#bdbdbd</color>
</resources>

Update:

This method was deprecated in API level 23. Use getColor(int, Theme) instead.

Check this.

here is a better answer found through Git docs.

This shows what the heroku remote is:

$ git remote get-url heroku

Found it here: https://git-scm.com/docs/git-remote Also in that document is a set-url, if you need to change it.

Which OS you are using ? For Windows : Go to Command Prompt

set path to www/{ur project}

For me : www/laravel5

Then type this command : composer install

It will automatically install all dependency in vendor/

I think jdk has certain features which can be used along with particular framework. Well call it SDK as a whole.

Like Android or Blackberry both use java along with their framework.

Those saying that you can't safely remove an item from a collection except through the Iterator aren't quite correct, you can do it safely using one of the concurrent collections such as ConcurrentHashMap.

Depending on how many dynamic classes you need to add as your project grows it's probably worth checking out the classnames utility by JedWatson on GitHub. It allows you to represent your conditional classes as an object and returns those that evaluate to true.

So as an example from its React documentation:

render () {

var btnClass = classNames({
  'btn': true,
  'btn-pressed': this.state.isPressed,
  'btn-over': !this.state.isPressed && this.state.isHovered
});

return <button className={btnClass}>I'm a button!</button>;

} 

Since React triggers a re-render when there is a state change, your dynamic class names are handled naturally and kept up to date with the state of your component.

Assign the values of nested json to struct until you know the underlying type of json keys:-

package main

import (
    "encoding/json"
    "fmt"
)

// Object
type Object struct {
    Foo map[string]map[string]string `json:"foo"`
    More string `json:"more"`
}

func main(){
    someJSONString := []byte(`{"foo":{ "bar": "1", "baz": "2" }, "more": "text"}`)
    var obj Object
    err := json.Unmarshal(someJSONString, &obj)
    if err != nil{
        fmt.Println(err)
    }
    fmt.Println("jsonObj", obj)
}

I ran into similar problem a while back and what was happening in my case was the outer recycler view was working perfectly fine but the the adapter of inner/second recycler view had minor issues all the methods like constructor got initiated and even getCount() method was being called, although the final methods responsible to generate view ie..

1. onBindViewHolder() methods never got called. --> Problem 1.

2. When it got called finally it never show the list items/rows of recycler view. --> Problem 2.

Reason why this happened :: When you put a recycler view inside another recycler view, then height of the first/outer recycler view is not auto adjusted. It is defined when the first/outer view is created and then it remains fixed. At that point your second/inner recycler view has not yet loaded its items and thus its height is set as zero and never changes even when it gets data. Then when onBindViewHolder() in your second/inner recycler view is called, it gets items but it doesn't have the space to show them because its height is still zero. So the items in the second recycler view are never shown even when the onBindViewHolder() has added them to it.

Solution :: you have to create your custom LinearLayoutManager for the second recycler view and that is it. To create your own LinearLayoutManager: Create a Java class with the name CustomLinearLayoutManager and paste the code below into it. NO CHANGES REQUIRED

public class CustomLinearLayoutManager extends LinearLayoutManager {

    private static final String TAG = CustomLinearLayoutManager.class.getSimpleName();

    public CustomLinearLayoutManager(Context context) {
        super(context);

    }

    public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

    private int[] mMeasuredDimension = new int[2];

    @Override
    public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state, int widthSpec, int heightSpec) {

        final int widthMode = View.MeasureSpec.getMode(widthSpec);
        final int heightMode = View.MeasureSpec.getMode(heightSpec);
        final int widthSize = View.MeasureSpec.getSize(widthSpec);
        final int heightSize = View.MeasureSpec.getSize(heightSpec);

        int width = 0;
        int height = 0;
        for (int i = 0; i < getItemCount(); i++) {
            measureScrapChild(recycler, i, View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    mMeasuredDimension);


            if (getOrientation() == HORIZONTAL) {
                width = width + mMeasuredDimension[0];
                if (i == 0) {
                    height = mMeasuredDimension[1];
                }
            } else {
                height = height + mMeasuredDimension[1];
                if (i == 0) {
                    width = mMeasuredDimension[0];
                }
            }
        }
        switch (widthMode) {
            case View.MeasureSpec.EXACTLY:
                width = widthSize;
            case View.MeasureSpec.AT_MOST:

        switch (heightMode) {
            case View.MeasureSpec.EXACTLY:
                height = heightSize;
            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        setMeasuredDimension(width, height);
    }

    private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                                   int heightSpec, int[] measuredDimension) {
        try {
            View view = recycler.getViewForPosition(position);

            if (view != null) {
                RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();

                int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
                        getPaddingLeft() + getPaddingRight(), p.width);

                int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
                        getPaddingTop() + getPaddingBottom(), p.height);

                view.measure(childWidthSpec, childHeightSpec);
                measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
                measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
                recycler.recycleView(view);
            }
        } catch (Exception e) {
            e.printStackTrace();

For me, it just was that service console restart didn't work after tomcat ran into an error. Only stop/start brought it back.

I had the problem with Tomcat running on Ubuntu. The issue was selinux was enabled and for some reason it would not let Eclipse connect to the debugging port. Disabling selinux or putting it in permissive mode solved the issue for me.

One script to rule them all: this combines truncate and delete commands with sp_MSforeachtable so that you can avoid dropping and recreating constraints - just specify the tables that need to be deleted rather than truncated and for my purposes I have included an extra schema filter for good measure (tested in 2008r2)

declare @schema nvarchar(max) = 'and Schema_Id=Schema_id(''Value'')'
declare @deletiontables nvarchar(max) = '(''TableA'',''TableB'')'
declare @truncateclause nvarchar(max) = @schema + ' and o.Name not in ' +  + @deletiontables;
declare @deleteclause nvarchar(max) = @schema + ' and o.Name in ' + @deletiontables;        

exec sp_MSforeachtable 'alter table ? nocheck constraint all', @whereand=@schema
exec sp_MSforeachtable 'truncate table ?', @whereand=@truncateclause
exec sp_MSforeachtable 'delete from ?', @whereand=@deleteclause
exec sp_MSforeachtable 'alter table ? with check check constraint all', @whereand=@schema

You have to instantiate the object first. The simplest way is:

var lab =["1","2","3"];
var val = [42,55,51,22];
var data = [];
for(var i=0; i<4; i++)  {
    data.push({label: lab[i], value: val[i]});
}

Or an other, less concise way, but closer to your original code:

for(var i=0; i<4; i++)  {
   data[i] = {};              // creates a new object
   data[i].label = lab[i];
   data[i].value = val[i];    
}

array() will not create a new array (unless you defined that function). Either Array() or new Array() or just [].

I recommend to read the MDN JavaScript Guide.

Unfortunately that approach is not portable C++ (so far).

All standard names are in namespace std and moreover you cannot know which names are NOT defined by including and header (in other words it's perfectly legal for an implementation to declare the name std::string directly or indirectly when using #include <vector>).

Despite this however you are required by the language to know and tell the compiler which standard header includes which part of the standard library. This is a source of portability bugs because if you forget for example #include <map> but use std::map it's possible that the program compiles anyway silently and without warnings on a specific version of a specific compiler, and you may get errors only later when porting to another compiler or version.

In my opinion there are no valid technical excuses because this is necessary for the general user: the compiler binary could have all standard namespace built in and this could actually increase the performance even more than precompiled headers (e.g. using perfect hashing for lookups, removing standard headers parsing or loading/demarshalling and so on).

The use of standard headers simplifies the life of who builds compilers or standard libraries and that's all. It's not something to help users.

However this is the way the language is defined and you need to know which header defines which names so plan for some extra neurons to be burnt in pointless configurations to remember that (or try to find and IDE that automatically adds the standard headers you use and removes the ones you don't... a reasonable alternative).

Using native Array.reduce

var array = [ {'id':'73' ,'foo':'bar'} , {'id':'45' ,'foo':'bar'} , ];
var id = 73;

var found = array.reduce(function(a, b){
    return (a.id==id && a) || (b.id == id && b)
});

returns the object element if found, otherwise false

Command prompt (Cmd.exe)

When the Docker CLI is used from the Windows Cmd.exe, use %cd% to mount the current directory:

echo test > test.txt
docker run --rm -v %cd%:/data busybox ls -ls /data/test.txt

Git Bash (MinGW)

When the Docker CLI is used from the Git Bash (MinGW), mounting the current directory may fail due to a POSIX path conversion: Docker mounted volume adds ;C to end of windows path when translating from linux style path.

Escape the POSIX paths by prefixing with /

To skip the path conversion, POSIX paths have to be prefixed with the slash (/) to have leading double slash (//), including /$(pwd)

touch test.txt
docker run --rm -v /$(pwd):/data busybox ls -la //data/test.txt

Disable the path conversion

Disable the POSIX path conversion in Git Bash (MinGW) by setting MSYS_NO_PATHCONV=1 environment variable at the command level

touch test.txt
MSYS_NO_PATHCONV=1 docker run --rm -v $(pwd):/data busybox ls -la /data/test.txt

or shell (system) level

export MSYS_NO_PATHCONV=1
touch test.txt
docker run --rm -v $(pwd):/data busybox ls -la /data/test.txt

This is just a thought. There is one very easy way to do it. If you just need number of words and not actual words then just use Apache WordUtils

import org.apache.commons.lang.WordUtils;

public class CountWord {

public static void main(String[] args) {    
String str = "Just keep a boolean flag around that lets you know if the previous character was whitespace or not pseudocode follows";

    String initials = WordUtils.initials(str);

    System.out.println(initials);
    //so number of words in your file will be
    System.out.println(initials.length());    
  }
}

create no vim swap file just for a particular file

autocmd bufenter  c:/aaa/Dropbox/TapNote/Todo.txt :set noswapfile

If you just want to remove one pod and keep others you may have installed, open the podfile in your app directory and delete the one you want to remove. Then navigate to your app directory using terminal and type:

pod update

This will remove the pod you removed from the podfile. You will see it has been removed in the terminal:

Analyzing dependencies
Removing FirebaseUI
Removing UICircularProgressRing

Note that this method will also pull any updates to the other pods in your podfile. You may or may not want that.
