This will try to detect whether a timestamp was given or not, and will also return future dates/times as negative values:

<?php

function time_diff($start, $end = NULL, $convert_to_timestamp = FALSE) {
  // If $convert_to_timestamp is not explicitly set to TRUE,
  // check to see if it was accidental:
  if ($convert_to_timestamp || !is_numeric($start)) {
    // If $convert_to_timestamp is TRUE, convert to timestamp:
    $timestamp_start = strtotime($start);
  }
  else {
    // Otherwise, leave it as a timestamp:
    $timestamp_start = $start;
  }
  // Same as above, but make sure $end has actually been overridden with a non-null,
  // non-empty, non-numeric value:
  if (!is_null($end) && (!empty($end) && !is_numeric($end))) {
    $timestamp_end = strtotime($end);
  }
  else {
    // If $end is NULL or empty and non-numeric value, assume the end time desired
    // is the current time (useful for age, etc):
    $timestamp_end = time();
  }
  // Regardless, set the start and end times to an integer:
  $start_time = (int) $timestamp_start;
  $end_time = (int) $timestamp_end;

  // Assign these values as the params for $then and $now:
  $start_time_var = 'start_time';
  $end_time_var = 'end_time';
  // Use this to determine if the output is positive (time passed) or negative (future):
  $pos_neg = 1;

  // If the end time is at a later time than the start time, do the opposite:
  if ($end_time <= $start_time) {
    $start_time_var = 'end_time';
    $end_time_var = 'start_time';
    $pos_neg = -1;
  }

  // Convert everything to the proper format, and do some math:

    $days += $days_last_month;
  }
  if ($months < 0) {
    $years -= 1;
    $months += 12;
  }

  // Finally, multiply each value by either 1 (in which case it will stay the same),
  // or by -1 (in which case it will become negative, for future dates).
  // Note: 0 * 1 == 0 * -1 == 0
  $out = new stdClass;
  $out->years = (int) $years * $pos_neg;
  $out->months = (int) $months * $pos_neg;
  $out->days = (int) $days * $pos_neg;
  $out->hours = (int) $hours * $pos_neg;
  $out->minutes = (int) $minutes * $pos_neg;
  $out->seconds = (int) $seconds * $pos_neg;
  return $out;
}

Example usage:

<?php
  $birthday = 'June 2, 1971';
  $check_age_for_this_date = 'June 3, 1999 8:53pm';
  $age = time_diff($birthday, $check_age_for_this_date)->years;
  print $age;// 28

Or:

<?php
  $christmas_2020 = 'December 25, 2020';
  $countdown = time_diff($christmas_2020);
  print_r($countdown);

You can always make simple xsd schema for 'packages.config' to get rid of this warning. To do this, create file named "packages.xsd":

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
      targetNamespace="urn:packages" xmlns="urn:packages">
  <xs:element name="packages">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="package" maxOccurs="unbounded">
          <xs:complexType>
            <xs:attribute name="id" type="xs:string" use="required" />
            <xs:attribute name="version" type="xs:string" use="required" />
            <xs:attribute name="targetFramework" type="xs:string" use="optional" />
            <xs:attribute name="allowedVersions" type="xs:string" use="optional" />
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

Location of this file (two options)

• In the same folder as 'packages.config' file,
• If you want to share packages.xsd across multiple projects, move it to the Visual Studio Schemas folder (the path may slightly differ, it's D:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas for me).

Then, edit <packages> tag in packages.config file (add xmlns attribute):

<packages xmlns="urn:packages">

Now the warning should disappear (even if packages.config file is open in Visual Studio).

Try:

msg['Subject'] = "Auto Hella Restart Report " + sys.argv[1]

The + operator is overridden in python to concatenate strings.

Quick way to enable MySQL General Query Log without restarting.

I think you should use null

SELECT CustomerName AS Customer, null AS Contact 
FROM Customers;

And Remember that Oracle

treats a character value with a length of zero as null.

Quick Answer

You should use the equals method since this is implemented to perform the comparison you want. toString() itself uses an iterator just like equals but it is a more inefficient approach. Additionally, as @Teepeemm pointed out, toString is affected by order of elements (basically iterator return order) hence is not guaranteed to provide the same output for 2 different maps (especially if we compare two different maps).

Note/Warning: Your question and my answer assume that classes implementing the map interface respect expected toString and equals behavior. The default java classes do so, but a custom map class needs to be examined to verify expected behavior.

See: http://docs.oracle.com/javase/7/docs/api/java/util/Map.html

boolean equals(Object o)

Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.

Implementation in Java Source (java.util.AbstractMap)

Additionally, java itself takes care of iterating through all elements and making the comparison so you don't have to. Have a look at the implementation of AbstractMap which is used by classes such as HashMap:

 // Comparison and hashing

    /**
     * Compares the specified object with this map for equality.  Returns
     * <tt>true</tt> if the given object is also a map and the two maps
     * represent the same mappings.  More formally, two maps <tt>m1</tt> and
     * <tt>m2</tt> represent the same mappings if
     * <tt>m1.entrySet().equals(m2.entrySet())</tt>.  This ensures that the
     * <tt>equals</tt> method works properly across different implementations
     * of the <tt>Map</tt> interface.
     *
     * <p>This implementation first checks if the specified object is this map;
     * if so it returns <tt>true</tt>.  Then, it checks if the specified
     * object is a map whose size is identical to the size of this map; if
     * not, it returns <tt>false</tt>.  If so, it iterates over this map's
     * <tt>entrySet</tt> collection, and checks that the specified map
     * contains each mapping that this map contains.  If the specified map
     * fails to contain such a mapping, <tt>false</tt> is returned.  If the
     * iteration completes, <tt>true</tt> is returned.
     *
     * @param o object to be compared for equality with this map
     * @return <tt>true</tt> if the specified object is equal to this map
     */
    public boolean equals(Object o) {
        if (o == this)
            return true;

        if (!(o instanceof Map))
            return false;
        Map<K,V> m = (Map<K,V>) o;
        if (m.size() != size())
            return false;

        try {
            Iterator<Entry<K,V>> i = entrySet().iterator();
            while (i.hasNext()) {
                Entry<K,V> e = i.next();
                K key = e.getKey();
                V value = e.getValue();
                if (value == null) {
                    if (!(m.get(key)==null && m.containsKey(key)))
                        return false;
                } else {
                    if (!value.equals(m.get(key)))
                        return false;
                }
            }
        } catch (ClassCastException unused) {
            return false;
        } catch (NullPointerException unused) {
            return false;
        }

        return true;
    }

Comparing two different types of Maps

toString fails miserably when comparing a TreeMap and HashMap though equals does compare contents correctly.

Code:

public static void main(String args[]) {
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("2", "whatever2");
map.put("1", "whatever1");
TreeMap<String, Object> map2 = new TreeMap<String, Object>();
map2.put("2", "whatever2");
map2.put("1", "whatever1");

System.out.println("Are maps equal (using equals):" + map.equals(map2));
System.out.println("Are maps equal (using toString().equals()):"
        + map.toString().equals(map2.toString()));

System.out.println("Map1:"+map.toString());
System.out.println("Map2:"+map2.toString());
}

Output:

Are maps equal (using equals):true
Are maps equal (using toString().equals()):false
Map1:{2=whatever2, 1=whatever1}
Map2:{1=whatever1, 2=whatever2}

I faced this issue, I was not able to copy zeppelin [1GB] directory into docker container and was getting issue

COPY failed: stat /var/lib/docker/tmp/docker-builder977188321/zeppelin-0.7.2-bin-all: no such file or directory

I am using docker Version: 17.09.0-ce and resolved the issue with the following steps.

Step 1: copy zeppelin directory [which i want to copy into docker package]into directory contain "Dockfile"

Step 2: edit Dockfile and add command [location where we want to copy] ADD ./zeppelin-0.7.2-bin-all /usr/local/

Step 3: go to directory which contain DockFile and run command [alternatives also available] docker build

Step 4: docker image created Successfully with logs

Step 5/9 : ADD ./zeppelin-0.7.2-bin-all /usr/local/ ---> 3691c902d9fe

Step 6/9 : WORKDIR $ZEPPELIN_HOME ---> 3adacfb024d8 .... Successfully built b67b9ea09f02

Remove the display:none, and use ng-show instead:

<ul class="procedures">
    <li ng-repeat="procedure in procedures | filter:query | orderBy:orderProp">
        <h4><a href="#" ng-click="showDetails = ! showDetails">{{procedure.definition}}</a></h4>
         <div class="procedure-details" ng-show="showDetails">
            <p>Number of patient discharges: {{procedure.discharges}}</p>
            <p>Average amount covered by Medicare: {{procedure.covered}}</p>
            <p>Average total payments: {{procedure.payments}}</p>
         </div>
    </li>
</ul>

Here's the fiddle: http://jsfiddle.net/asmKj/

You can also use ng-class to toggle a class:

<div class="procedure-details" ng-class="{ 'hidden': ! showDetails }">

I like this more, since it allows you to do some nice transitions: http://jsfiddle.net/asmKj/1/

The usual way to use assertRaises is to call a function:

self.assertRaises(TypeError, test_function, args)

to test that the function call test_function(args) raises a TypeError.

The problem with self.testListNone[:1] is that Python evaluates the expression immediately, before the assertRaises method is called. The whole reason why test_function and args is passed as separate arguments to self.assertRaises is to allow assertRaises to call test_function(args) from within a try...except block, allowing assertRaises to catch the exception.

Since you've defined self.testListNone = None, and you need a function to call, you might use operator.itemgetter like this:

import operator
self.assertRaises(TypeError, operator.itemgetter, (self.testListNone,slice(None,1)))

since

operator.itemgetter(self.testListNone,slice(None,1))

is a long-winded way of saying self.testListNone[:1], but which separates the function (operator.itemgetter) from the arguments.

small update for swift 5:

let refreshAlert = UIAlertController(title: "Refresh", message: "All data will be lost.", preferredStyle: UIAlertController.Style.alert)

    refreshAlert.addAction(UIAlertAction(title: "Ok", style: .default, handler: { (action: UIAlertAction!) in
          print("Handle Ok logic here")
    }))

    refreshAlert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (action: UIAlertAction!) in
          print("Handle Cancel Logic here")
    }))

    self.present(refreshAlert, animated: true, completion: nil)

This is not the exact answer for your question, but this may help you

public class JsonParser {

    private static DefaultHttpClient httpClient = ConnectionManager.getClient();

    public static List<Club> getNearestClubs(double lat, double lon) {
        // YOUR URL GOES HERE
        String getUrl = Constants.BASE_URL + String.format("getClosestClubs?lat=%f&lon=%f", lat, lon);

        List<Club> ret = new ArrayList<Club>();

        HttpResponse response = null;
        HttpGet getMethod = new HttpGet(getUrl);
        try {
            response = httpClient.execute(getMethod);

            // CONVERT RESPONSE TO STRING
            String result = EntityUtils.toString(response.getEntity());

            // CONVERT RESPONSE STRING TO JSON ARRAY
            JSONArray ja = new JSONArray(result);

            // ITERATE THROUGH AND RETRIEVE CLUB FIELDS
            int n = ja.length();
            for (int i = 0; i < n; i++) {
                // GET INDIVIDUAL JSON OBJECT FROM JSON ARRAY
                JSONObject jo = ja.getJSONObject(i);

                // RETRIEVE EACH JSON OBJECT'S FIELDS
                long id = jo.getLong("id");
                String name = jo.getString("name");
                String address = jo.getString("address");
                String country = jo.getString("country");
                String zip = jo.getString("zip");
                double clat = jo.getDouble("lat");
                double clon = jo.getDouble("lon");
                String url = jo.getString("url");
                String number = jo.getString("number");

                // CONVERT DATA FIELDS TO CLUB OBJECT
                Club c = new Club(id, name, address, country, zip, clat, clon, url, number);
                ret.add(c);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        // RETURN LIST OF CLUBS
        return ret;
    }

}
Again, it’s relatively straight forward, but the methods I’ll make special note of are:

JSONArray ja = new JSONArray(result);
JSONObject jo = ja.getJSONObject(i);
long id = jo.getLong("id");
String name = jo.getString("name");
double clat = jo.getDouble("lat");

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

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

Your stored procedures work as coded. The problem is with the last line, it is unable to invoke either of your stored procedures.

Three choices in SQL*Plus are: call, exec, and an anoymous PL/SQL block.

call appears to be a SQL keyword, and is documented in the SQL Reference. http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_4008.htm#BABDEHHG The syntax diagram indicates that parentesis are required, even when no arguments are passed to the call routine.

CALL test_sp_1();

An anonymous PL/SQL block is PL/SQL that is not inside a named procedure, function, trigger, etc. It can be used to call your procedure.

BEGIN
    test_sp_1;
END;
/

Exec is a SQL*Plus command that is a shortcut for the above anonymous block. EXEC <procedure_name> will be passed to the DB server as BEGIN <procedure_name>; END;

Full example:

SQL> SET SERVEROUTPUT ON
SQL> CREATE OR REPLACE PROCEDURE test_sp 
  2  AS 
  3  BEGIN 
  4      DBMS_OUTPUT.PUT_LINE('Test works'); 
  5  END;
  6  /

Procedure created.

SQL> CREATE OR REPLACE PROCEDURE test_sp_1 
  2  AS
  3  BEGIN
  4      DBMS_OUTPUT.PUT_LINE('Testing'); 
  5      test_sp; 
  6  END;
  7  /

Procedure created.

SQL> CALL test_sp_1();
Testing
Test works

Call completed.

SQL> exec test_sp_1
Testing
Test works

PL/SQL procedure successfully completed.

SQL> begin
  2      test_sp_1;
  3  end;

For multiple classes in the same js file, extending Component from @wordpress/element, you can do that :

// classes.js
import { Component } from '@wordpress/element';

const Class1 = class extends Component {
}

const Class2 = class extends Component {
}

export { Class1, Class2 }

And import them in another js file :

import { Class1, Class2 } from './classes';

If the only issue is height, just using divs seems to work:

<div id="header">header content</div>
<div id="content" style="height:100%">content content</div>

In a simple test, the width of header/content is different in your example and mine, but I'm not sure from your post if you're concerned about the width?

The accepted answer only renamed the user but the privileges were left behind.

I'd recommend using:

RENAME USER 'foo'@'1.2.3.4' TO 'foo'@'1.2.3.5';

According to MySQL documentation:

RENAME USER causes the privileges held by the old user to be those held by the new user.

Make sure your element with the .date-picker class does NOT already have a hasDatepicker class. If it does, even an attempt to re-initialize with $myDatepicker.datepicker(); will fail! Instead you need to do...

$myDatepicker.removeClass('hasDatepicker').datepicker();

Why not? You can use switch implementation with equivalent syntax and same semantics. The C language does not have objects and strings objects at all, but strings in C is null terminated strings referenced by pointer. The C++ language have possibility to make overload functions for objects comparision or checking objects equalities. As C as C++ is enough flexible to have such switch for strings for C language and for objects of any type that support comparaison or check equality for C++ language. And modern C++11 allow to have this switch implementation enough effective.

Your code will be like this:

std::string name = "Alice";

std::string gender = "boy";
std::string role;

SWITCH(name)
  CASE("Alice")   FALL
  CASE("Carol")   gender = "girl"; FALL
  CASE("Bob")     FALL
  CASE("Dave")    role   = "participant"; BREAK
  CASE("Mallory") FALL
  CASE("Trudy")   role   = "attacker";    BREAK
  CASE("Peggy")   gender = "girl"; FALL
  CASE("Victor")  role   = "verifier";    BREAK
  DEFAULT         role   = "other";
END

// the role will be: "participant"
// the gender will be: "girl"

It is possible to use more complicated types for example std::pairs or any structs or classes that support equality operations (or comarisions for quick mode).

Features

• any type of data which support comparisions or checking equality
• possibility to build cascading nested switch statemens.
• possibility to break or fall through case statements
• possibility to use non constatnt case expressions
• possible to enable quick static/dynamic mode with tree searching (for C++11)

Sintax differences with language switch is

• uppercase keywords
• need parentheses for CASE statement
• semicolon ';' at end of statements is not allowed
• colon ':' at CASE statement is not allowed
• need one of BREAK or FALL keyword at end of CASE statement

For C++97 language used linear search. For C++11 and more modern possible to use quick mode wuth tree search where return statement in CASE becoming not allowed. The C language implementation exists where char* type and zero-terminated string comparisions is used.

Read more about this switch implementation.

bool is an alias for Boolean. What aliases do is replace one string of text with another (like search/replace-all in notepad++), just before the code is compiled. Using one over the other has no effect at run-time.

In most other languages, one would be a primitive type and the other would be an object type (value type and reference type in C# jargon). C# does not give you the option of choosing between the two. When you want to call a static method defined in the Boolean class, it auto-magically treats Boolean as a reference type. If you create a new Boolean variable, it auto-magically treats it as a reference type (unless you use the Activator.CreateInstance method).

From Activity#showDialog(int):

This method is deprecated.
Use the new DialogFragment class with FragmentManager instead; this is also available on older platforms through the Android compatibility package.

In the Oracle RDBMS, it is possible to use a multi-row subquery in the select clause as long as the (sub-)output is encapsulated as a collection. In particular, a multi-row select clause subquery can output each of its rows as an xmlelement that is encapsulated in an xmlforest.

I wanted to maintain my table while pulling in one row that gives me the last value in a particular column in the table. I essentially was looking to replace the LAST() function in excel and this worked.

, (Select column_name FROM report WHERE rowid = (select last_insert_rowid() from report))

I looked around for an answer to this and the best way I found was to use Flex and inline styling on different components.

For example, to make two paper components divide my full screen in 2 vertical components (in ration of 1:4), the following code works fine.

const styles = {
  div:{
    display: 'flex',
    flexDirection: 'row wrap',
    padding: 20,
    width: '100%'
  },
  paperLeft:{
    flex: 1,
    height: '100%',
    margin: 10,
    textAlign: 'center',
    padding: 10
  },
  paperRight:{
    height: 600,
    flex: 4,
    margin: 10,
    textAlign: 'center',
  }
};

class ExampleComponent extends React.Component {
  render() {
    return (
      <div>
        <div style={styles.div}>
          <Paper zDepth={3} style={styles.paperLeft}>
            <h4>First Vertical component</h4>
          </Paper>
          <Paper zDepth={3} style={styles.paperRight}>
              <h4>Second Vertical component</h4>
          </Paper>
        </div>
      </div>
    )
  }
}

Now, with some more calculations, you can easily divide your components on a page.

Further Reading on flex

Easier way is also to do this.

let elementReference = document.querySelector('<your css, #id selector>');
    if (elementReference instanceof HTMLElement) {
        elementReference.focus();
    }

You can use java.lang.Runtime.exec to run simple code. This gives you back a Process and you can read its standard output directly without having to temporarily store the output on disk.

For example, here's a complete program that will showcase how to do it:

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class testprog {
    public static void main(String args[]) {
        String s;
        Process p;
        try {
            p = Runtime.getRuntime().exec("ls -aF");
            BufferedReader br = new BufferedReader(
                new InputStreamReader(p.getInputStream()));
            while ((s = br.readLine()) != null)
                System.out.println("line: " + s);
            p.waitFor();
            System.out.println ("exit: " + p.exitValue());
            p.destroy();
        } catch (Exception e) {}
    }
}

When compiled and run, it outputs:

line: ./
line: ../
line: .classpath*
line: .project*
line: bin/
line: src/
exit: 0

as expected.

You can also get the error stream for the process standard error, and output stream for the process standard input, confusingly enough. In this context, the input and output are reversed since it's input from the process to this one (i.e., the standard output of the process).

If you want to merge the process standard output and error from Java (as opposed to using 2>&1 in the actual command), you should look into ProcessBuilder.

None of the solutions worked for me, so I had to use a WebClient instead of a HttpWebRequest and the issue was no more.

I needed to use a CookieContainer, so I used the solution posted by Pavel Savara in this thread - Using CookieContainer with WebClient class

just remove "protected" from this line:

private readonly CookieContainer container = new CookieContainer();

In MySQL, @variable indicates a user-defined variable. You can define your own.

SET @a = 'test';
SELECT @a;

Outside of stored programs, a variable, without @, is a system variable, which you cannot define yourself.

The scope of this variable is the entire session. That means that while your connection with the database exists, the variable can still be used.

This is in contrast with MSSQL, where the variable will only be available in the current batch of queries (stored procedure, script, or otherwise). It will not be available in a different batch in the same session.

You can do this by using Year(), Month() Day() and datepart().

In you example this would be:

select  Closing_Date, Category,  COUNT(Status)TotalCount from  MyTable
where Closing_Date >= '2012-02-01' and Closing_Date <= '2012-12-31' 
and Defect_Status1 is not null 
group by Year(Closing_Date), Month(Closing_Date), Category

One approach (which I can't imagine is good programming practice) is to add the ... which is traditionally used to pass arguments specified in one function to another.

> multiply <- function(a,b) a*b
> multiply(a = 2,b = 4,c = 8)
Error in multiply(a = 2, b = 4, c = 8) : unused argument(s) (c = 8)
> multiply2 <- function(a,b,...) a*b
> multiply2(a = 2,b = 4,c = 8)
[1] 8

QUOTE from link: "This download will install a set of components that can be used to facilitate transfer of data between 2010 Microsoft Office System files and non-Microsoft Office applications"

I made a helper interface for this using the holder pattern.

public interface StyleHolder<V extends View> {
    void applyStyle(V view);
}

Now for every style you want to use pragmatically just implement the interface, for example:

public class ButtonStyleHolder implements StyleHolder<Button> {

    private final Drawable background;
    private final ColorStateList textColor;
    private final int textSize;

    public ButtonStyleHolder(Context context) {
        TypedArray ta = context.obtainStyledAttributes(R.style.button, R.styleable.ButtonStyleHolder);

        Resources resources = context.getResources();

        background = ta.getDrawable(ta.getIndex(R.styleable.ButtonStyleHolder_android_background));

        textColor = ta.getColorStateList(ta.getIndex(R.styleable.ButtonStyleHolder_android_textColor));

        textSize = ta.getDimensionPixelSize(
                ta.getIndex(R.styleable.ButtonStyleHolder_android_textSize),
                resources.getDimensionPixelSize(R.dimen.standard_text_size)
        );

        // Don't forget to recycle!
        ta.recycle();
    }

    @Override
    public void applyStyle(Button btn) {
        btn.setBackground(background);
        btn.setTextColor(textColor);
        btn.setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize);
    }
}

Declare a stylable in your attrs.xml, the styleable for this example is:

<declare-styleable name="ButtonStyleHolder">
    <attr name="android:background" />
    <attr name="android:textSize" />
    <attr name="android:textColor" />
</declare-styleable>

Here is the style declared in styles.xml:

<style name="button">
    <item name="android:background">@drawable/button</item>
    <item name="android:textColor">@color/light_text_color</item>
    <item name="android:textSize">@dimen/standard_text_size</item>
</style>

And finally the implementation of the style holder:

Button btn = new Button(context);    
StyleHolder<Button> styleHolder = new ButtonStyleHolder(context);
styleHolder.applyStyle(btn);

I found this very helpful as it can be easily reused and keeps the code clean and verbose, i would recommend using this only as a local variable so we can allow the garbage collector to do its job once we're done with setting all the styles.

Superclass constructor CAN'T be inherited in extended class. Although it can be invoked in extended class constructor's with super() as the first statement.

Be aware that caches do not just cache continuous memory. They have multiple lines (at least 4) so discontinous and overlapping memory can often be stored just as efficiently.

What is missing from all the above examples is measured benchmarks. There are many myths about performance. Unless you measure it you do not know. Do not complicate your code unless you have a measured improvement.

Reinstall java and choose a destination folder without a space

I assume your game has a main loop, and all your sprites are in a list called sprites.

In your main loop, get all events, and check for the MOUSEBUTTONDOWN or MOUSEBUTTONUP event.

while ... # your main loop
  # get all events
  ev = pygame.event.get()

  # proceed events
  for event in ev:

    # handle MOUSEBUTTONUP
    if event.type == pygame.MOUSEBUTTONUP:
      pos = pygame.mouse.get_pos()

      # get a list of all sprites that are under the mouse cursor
      clicked_sprites = [s for s in sprites if s.rect.collidepoint(pos)]
      # do something with the clicked sprites...

So basically you have to check for a click on a sprite yourself every iteration of the mainloop. You'll want to use mouse.get_pos() and rect.collidepoint().

Pygame does not offer event driven programming, as e.g. cocos2d does.

Another way would be to check the position of the mouse cursor and the state of the pressed buttons, but this approach has some issues.

if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()):
  print ("You have opened a chest!")

You'll have to introduce some kind of flag if you handled this case, since otherwise this code will print "You have opened a chest!" every iteration of the main loop.

handled = False

while ... // your loop

  if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()) and not handled:
    print ("You have opened a chest!")
    handled = pygame.mouse.get_pressed()[0]

Of course you can subclass Sprite and add a method called is_clicked like this:

class MySprite(Sprite):
  ...

  def is_clicked(self):
    return pygame.mouse.get_pressed()[0] and self.rect.collidepoint(pygame.mouse.get_pos())

So, it's better to use the first approach IMHO.

Alternatively, this

def simpleaxis(ax):
    ax.spines['top'].set_visible(False)
    ax.spines['right'].set_visible(False)
    ax.get_xaxis().tick_bottom()
    ax.get_yaxis().tick_left()

seems to achieve the same effect on an axis without losing rotated label support.

(Matplotlib 1.0.1; solution inspired by this).

Do not use the * selector as that will apply to all elements on the page. Suppose you have a structure like this:

...
<body>
    <div id="content">
        <b>This is the main container.</b>
    </div>
</body>
</html>

You can then center the #content div using:

#content {
    width: 400px;
    margin: 0 auto;
    background-color: #66ffff;
}

Don't know what you've seen elsewhere but this is the way to go. The * { margin: 0; padding: 0; } snippet you've seen is for resetting browser's default definitions for all browsers to make your site behave similarly on all browsers, this has nothing to do with centering the main container.

Most browsers apply a default margin and padding to some elements which usually isn't consistent with other browsers' implementations. This is why it is often considered smart to use this kind of 'resetting'. The reset snippet you presented is the most simplest of reset stylesheets, you can read more about the subject here:

• http://meyerweb.com/eric/tools/css/reset/

Select "File" -> "Project Structure".

Under "Project Settings" select "Project"

From there you can select the "Project SDK".

It's short hand for the ternary operator.

FormsAuth = (formsAuth != null) ? formsAuth : new FormsAuthenticationWrapper();

Or for those who don't do ternary:

if (formsAuth != null)
{
  FormsAuth = formsAuth;
}
else
{
  FormsAuth = new FormsAuthenticationWrapper();
}

You're missing the data-toggle="tab" data-tag on your menu urls so your scripts can't tell where your tab switches are:

HTML

<ul class="nav nav-tabs" data-tabs="tabs">
    <li class="active"><a data-toggle="tab" href="#red">Red</a></li>
    <li><a data-toggle="tab" href="#orange">Orange</a></li>
    <li><a data-toggle="tab" href="#yellow">Yellow</a></li>
    <li><a data-toggle="tab" href="#green">Green</a></li>
    <li><a data-toggle="tab" href="#blue">Blue</a></li>
</ul>

You can use instance_of?

e.g

@some_var.instance_of?(Hash)

I had a problem with redirection also. I tried everything that was proposed on Stackoverflow. The one case I found by myself is:

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP:SSL} !=1 [NC]
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

text = text.replace(/</g, '&lt;').replace(/>/g, '&gt;').replace(/\n/g, '<br/>');

It is worth noting, the library that John Slegers mentioned does have a jQuery dependency, however here is a version that is vanilla Javascript.

https://github.com/EldonMcGuinness/querystring.js

I would have simply commented on his post, but I lack the reputation to do so. :/

Example:

The example below process the following, albeit irregular, query string:

?foo=bar&foo=boo&roo=bar;bee=bop;=ghost;=ghost2;&;checkbox%5B%5D=b1;checkbox%5B%5D=b2;dd=;http=http%3A%2F%2Fw3schools.com%2Fmy%20test.asp%3Fname%3Dst%C3%A5le%26car%3Dsaab&http=http%3A%2F%2Fw3schools2.com%2Fmy%20test.asp%3Fname%3Dst%C3%A5le%26car%3Dsaab 

var qs = "?foo=bar&foo=boo&roo=bar;bee=bop;=ghost;=ghost2;&;checkbox%5B%5D=b1;checkbox%5B%5D=b2;dd=;http=http%3A%2F%2Fw3schools.com%2Fmy%20test.asp%3Fname%3Dst%C3%A5le%26car%3Dsaab&http=http%3A%2F%2Fw3schools2.com%2Fmy%20test.asp%3Fname%3Dst%C3%A5le%26car%3Dsaab";_x000D_
//var qs = "?=&=";_x000D_
//var qs = ""_x000D_
_x000D_
var results = querystring(qs);_x000D_
_x000D_
(document.getElementById("results")).innerHTML =JSON.stringify(results, null, 2);

<script _x000D_
src="https://rawgit.com/EldonMcGuinness/querystring.js/master/dist/querystring.min.js"></script>_x000D_
<pre id="results">RESULTS: Waiting...</pre>

You can set your content-type header so clients know to expect json

w.Header().Set("Content-Type", "application/json")

Another way to marshal a struct to json is to build an encoder using the http.ResponseWriter

// get a payload p := Payload{d}
json.NewEncoder(w).Encode(p)

I would use git restore (available since git 2.23)

git restore --source otherbranch path/to/myfile.txt

Why it is better than other options?

git checkout otherbranch -- path/to/myfile.txt - It copy file to working directory but also to staging area (similar effect as if you would copy this file manually and executed git add on it). git restore doesn't touch staging area (unless told it to by --staged option).

git show otherbranch:path/to/myfile.txt > path/to/myfile.txt uses standard shell redirection. If you use Powershell then there might be problem with text enconding or you could get broken file if it's binary. With git restore changing files is done all by git executable.

Another advantage is that you can restore whole folder with:

git restore --source otherbranch path/to

or with git restore --overlay --source otherbranch path/to if you want to avoid deleting files. For example if there is less files on otherbranch than in current working directory (and these files are tracked) without --overlay option git restore will delete them. But this is good default bahaviour, you most likely want the state of directory to be "the same like in otherbranch", not "the same like in otherbranch but with additional files from my current branch"

This was my approach using Kotlin:

private fun getHashFromEmailString(email : String) : String{
    val charset = Charsets.UTF_8
    val byteArray = email.toByteArray(charset)
    val digest = MessageDigest.getInstance("SHA-256")
    val hash = digest.digest(byteArray)

    return hash.fold("", { str, it -> str + "%02x".format(it)})
}

There's no real need to initialize to smallest/largest possible to find the smallest/largest in the array:

double largest = smallest = array[0];
for (int i=1; i<array_size; i++) {
    if (array[i] < smallest)
        smallest = array[i];
    if (array[i] > largest0
        largest= array[i];
}

Or, if you're doing it more than once:

#include <utility>

template <class iter>
std::pair<typename iter::value_type, typename iter::value_type> find_extrema(iter begin, iter end) {
    std::pair<typename iter::value_type, typename iter::value_type> ret;
    ret.first = ret.second = *begin;
    while (++begin != end) {
        if (*begin < ret.first)
           ret.first = *begin;
        if (*begin > ret.second)
           ret.second = *begin;
   }
   return ret;
}

The disadvantage of providing sample code -- I see others have already suggested the same idea.

Note that while the standard has a min_element and max_element, using these would require scanning through the data twice, which could be a problem if the array is large at all. Recent standards have addressed this by adding a std::minmax_element, which does the same as the find_extrema above (find both the minimum and maximum elements in a collection in a single pass).

Edit: Addressing the problem of finding the smallest non-zero value in an array of unsigned: observe that unsigned values "wrap around" when they reach an extreme. To find the smallest non-zero value, we can subtract one from each for the comparison. Any zero values will "wrap around" to the largest possible value for the type, but the relationship between other values will be retained. After we're done, we obviously add one back to the value we found.

unsigned int min_nonzero(std::vector<unsigned int> const &values) { 
    if (vector.size() == 0)
        return 0;
    unsigned int temp = values[0]-1;
    for (int i=1; i<values.size(); i++)
        if (values[i]-1 < temp)
            temp = values[i]-1;
    return temp+1;
}

Note this still uses the first element for the initial value, but we still don't need any "special case" code -- since that will wrap around to the largest possible value, any non-zero value will compare as being smaller. The result will be the smallest nonzero value, or 0 if and only if the vector contained no non-zero values.

I understand this is a very old thread. However, wanted to share how I encountered the message in my scenario and in case it might help others

1. I created an Add-Migration <Migration_name> on my local machine. Didn't run the update-database yet.
2. Meanwhile, there were series of commits in parent branch that I must down merge. The merge also had a migration to it and when I fixed conflicts, I ended up having 2 migrations that are added to my project but are not executed via update-database.
3. Now I don't use enable-migrations -force in my application. Rather my preferred way is execute the update-database -script command to control the target migrations I need.
4. So, when I attempted the above command, I get the error in question.

My solution was to run update-database -Script -TargetMigration <migration_name_from_merge> and then my update-database -Script -TargetMigration <migration_name> which generated 2 scripts that I was able to run manually on my local db.

Needless to say above experience is on my local machine.

The easiest way to be sure that you have created the runnable JAR file correctly, with the appropriate manifest file, is to use Eclipse to build it for you. In your Eclipse project, you basically just select File/Export from the menu, and follow the prompts.

That way, you can be sure that your JAR file is correct and will know to look elsewhere if there is still an issue. The process is described in full in FAQ How do I create an executable JAR file for a stand-alone SWT program?.

Celery doesn't support relative imports so in my celeryconfig.py, you need absolute import.

CELERYBEAT_SCHEDULE = {
        'add_num': {
            'task': 'app.tasks.add_num.add_nums',
            'schedule': timedelta(seconds=10),
            'args': (1, 2)
        }
}

The proper interval to get one second is 1000. The Interval property is the time between ticks in milliseconds:

MSDN: Timer.Interval Property

So, it's not the interval that you set that is wrong. Check the rest of your code for something like changing the interval of the timer, or binding the Tick event multiple times.

Keep both lists x and y in sorted order.

If x = y, do your action, if x < y, advance x, if y < x, advance y until either list is empty.

The run time of this intersection is proportional to min (size (x), size (y))

Don't run a .Contains () loop, this is proportional to x * y which is much worse.

If you always search based on value3, you could store the objects in a Map:

Map<String, List<Sample>> map = new HashMap <>();

You can then populate the map with key = value3 and value = list of Sample objects with that same value3 property.

You can then query the map:

List<Sample> allSamplesWhereValue3IsDog = map.get("Dog");

Note: if no 2 Sample instances can have the same value3, you can simply use a Map<String, Sample>.

In layman's language, it is like you are making a cake and you will need 5-10 ingredients from fridge. You have two options, get all ingredients from fridge and put it on your kitchen platform, or bring the item you want when you need.

Similarly, in eager loading, you fetch all information about bean and its related classes (not child or is-a relation but has a relationship, i.e. cake has flour, has milk, has cream etc), and in case of lazy loading, first you bring only its identifier and values that are coming from same table (necessary ingredients that first you will need in your bowl in case of cake). All information that is coming from other tables will be fetched as and when required/used.

you can also use:

pip install package==0.5.*

which is more consistent and easy to read.

If the exponent is constant and small, expand it out, minimizing the number of multiplications. (For example, x^4 is not optimally x*x*x*x, but y*y where y=x*x. And x^5 is y*y*x where y=x*x. And so on.) For constant integer exponents, just write out the optimized form already; with small exponents, this is a standard optimization that should be performed whether the code has been profiled or not. The optimized form will be quicker in so large a percentage of cases that it's basically always worth doing.

(If you use Visual C++, std::pow(float,int) performs the optimization I allude to, whereby the sequence of operations is related to the bit pattern of the exponent. I make no guarantee that the compiler will unroll the loop for you, though, so it's still worth doing it by hand.)

[edit] BTW pow has a (un)surprising tendency to crop up on the profiler results. If you don't absolutely need it (i.e., the exponent is large or not a constant), and you're at all concerned about performance, then best to write out the optimal code and wait for the profiler to tell you it's (surprisingly) wasting time before thinking further. (The alternative is to call pow and have the profiler tell you it's (unsurprisingly) wasting time -- you're cutting out this step by doing it intelligently.)

You could run: mvn exec:exec -Dexec.args="arg1".

This will pass the argument arg1 to your program.

You should specify the main class fully qualified, for example, a Main.java that is in a package test would need

mvn exec:java  -Dexec.mainClass=test.Main

By using the -f parameter, as decribed here, you can also run it from other directories.

mvn exec:java -Dexec.mainClass=test.Main -f folder/pom.xm

For multiple arguments, simply separate them with a space as you would at the command line.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="arg1 arg2 arg3"

For arguments separated with a space, you can group using 'argument separated with space' inside the quotation marks.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="'argument separated with space' 'another one'"

I agree with Shivam's answer except for textract doesn't exist for windows. And, for some reason antiword also fails to read the '.doc' files and gives an error:

'filename.doc' is not a word document. # This happens when the file wasn't generated via MS Office. Eg: Web-pages may be stored in .doc format offline.

So, I've got the following workaround to extract the text:

from bs4 import BeautifulSoup as bs
soup = bs(open(filename).read())
[s.extract() for s in soup(['style', 'script'])]
tmpText = soup.get_text()
text = "".join("".join(tmpText.split('\t')).split('\n')).encode('utf-8').strip()
print text

This script will work with most kinds of files. Have fun!

you should try this:

document.documentElement.outerHTML

Following on from kR105's reply above:

My problem was similar to that of the OP (Original Poster), only occurred outside a table, so the subclasses were not called from within the scope of the parent class (the table), but outside of it, so I had to ADD selectors, as kR105 mentioned.

Here was the problem: I had two boxes (divs), each with the same border-radius (HTML5), padding and margin, but needed to make them different colors. Rather than repeat those 3 parameters for each color class, I wanted a "superclass" to contain border-radius/padding/margin, then just individual "subclasses" to express their differences (double quotes around each as they're not really subclasses - see my later post). Here's how it worked out:

HTML:

<body>
  <div class="box box1"> Hello my color is RED </div>
  <div class="box box2"> Hello my color is BLUE </div>
</body>

CSS:

div.box {border-radius:20px 20px 20px 20px; padding:10px; margin:10px}
div.box1 {border:3px solid red; color:red}
div.box2 {border:3px solid blue; color:blue}

Hope someone finds this helpful.

Some compilers have different sizes for int on different platforms (not C# specific)

Some coding standards (MISRA C) requires that all types used are size specified (i.e. Int32 and not int).

It is also good to specify prefixes for different type variables (e.g. b for 8 bit byte, w for 16 bit word, and l for 32 bit long word => Int32 lMyVariable)

You should care because it makes your code more portable and more maintainable.

Portable may not be applicable to C# if you are always going to use C# and the C# specification will never change in this regard.

Maintainable ihmo will always be applicable, because the person maintaining your code may not be aware of this particular C# specification, and miss a bug were the int occasionaly becomes more than 2147483647.

In a simple for-loop that counts for example the months of the year, you won't care, but when you use the variable in a context where it could possibly owerflow, you should care.

You should also care if you are going to do bit-wise operations on it.

I'm quite surprised nobody mentioned the open-source project gogs (http://gogs.io) or a derived fork of it called gitea (http://gitea.io) which basically offers the same what gitlab does, but with minimal system resources (low footprint), being perfect to run in a Raspberry Pi for example. Installation and maintenance is also way simpler.

I had to use vbLf only in an ASP script where the original data was POSTed from a PHP script on a cPanel box over to ASP on a win server

(VBScript)

EmailText = Replace(EmailText, vbLf, "<br>")

test -z returns true if the parameter is empty (see man sh or man test).

Specifically, the MySQLi extension provides the following extremely useful benefits over the old MySQL extension..

OOP Interface (in addition to procedural) Prepared Statement Support Transaction + Stored Procedure Support Nicer Syntax Speed Improvements Enhanced Debugging

PDO Extension

PHP Data Objects extension is a Database Abstraction Layer. Specifically, this is not a MySQL interface, as it provides drivers for many database engines (of course including MYSQL).

PDO aims to provide a consistent API that means when a database engine is changed, the code changes to reflect this should be minimal. When using PDO, your code will normally "just work" across many database engines, simply by changing the driver you're using.

In addition to being cross-database compatible, PDO also supports prepared statements, stored procedures and more, whilst using the MySQL Driver.

f1 = open("input1.txt", "r")
print(f1.readline())

I just want to edit this for posterity that the tags for oracle weren't added when I answered this question. My response was more applicable to MS SQL.

Merge join is the best possible as it exploits the ordering, resulting in a single pass down the tables to do the join. IF you have two tables (or covering indexes) that have their ordering the same such as a primary key and an index of a table on that key then a merge join would result if you performed that action.

Hash join is the next best, as it's usually done when one table has a small number (relatively) of items, its effectively creating a temp table with hashes for each row which is then searched continuously to create the join.

Worst case is nested loop which is order (n * m) which means there is no ordering or size to exploit and the join is simply, for each row in table x, search table y for joins to do.

I was failing to send a body on a DELETE that required one and was getting this message as a result.

You want matplotlib.pcolor:

import numpy as np 
from pandas import DataFrame
import matplotlib.pyplot as plt

index = ['aaa', 'bbb', 'ccc', 'ddd', 'eee']
columns = ['A', 'B', 'C', 'D']
df = DataFrame(abs(np.random.randn(5, 4)), index=index, columns=columns)

plt.pcolor(df)
plt.yticks(np.arange(0.5, len(df.index), 1), df.index)
plt.xticks(np.arange(0.5, len(df.columns), 1), df.columns)
plt.show()

This gives:

To increase the amount of memory allocated to R you can use memory.limit

memory.limit(size = ...)

Or

memory.size(max = ...)

About the arguments

• size - numeric. If NA report the memory limit, otherwise request a new limit, in Mb. Only values of up to 4095 are allowed on 32-bit R builds, but see ‘Details’.
• max - logical. If TRUE the maximum amount of memory obtained from the OS is reported, if FALSE the amount currently in use, if NA the memory limit.

Using MAP you can have 2 arrays in the output: One containing the occurrences & the other one is containing the number of occurrences.

const dataset = [2,2,4,2,6,4,7,8,5,6,7,10,10,10,15];_x000D_
let values = [];_x000D_
let keys = [];_x000D_
_x000D_
var mapWithOccurences = dataset.reduce((a,c) => {_x000D_
  if(a.has(c)) a.set(c,a.get(c)+1);_x000D_
  else a.set(c,1);_x000D_
  return a;_x000D_
}, new Map())_x000D_
.forEach((value, key, map) => {_x000D_
  keys.push(key);_x000D_
  values.push(value);_x000D_
});_x000D_
_x000D_
_x000D_
console.log(keys)_x000D_
console.log(values)

If you want to measure code efficiency, or in any other way measure time intervals, the following will be easier:

#include <time.h>

int main()
{
   clock_t start = clock();
   //... do work here
   clock_t end = clock();
   double time_elapsed_in_seconds = (end - start)/(double)CLOCKS_PER_SEC;
   return 0;
}

Switch in itself isn't that bad, but if you have lots of "switch" or "if/else" on objects in your methods it may be a sign that your design is a bit "procedural" and that your objects are just value buckets. Move the logic to your objects, invoke a method on your objects and let them decide how to respond instead.

Looking at current hacky solutions in here, I feel I have to describe a proper solution after all.

First, you need to install the cygwin package ca-certificates via Cygwin's setup.exe to get the certificates.

Do NOT use curl or similar hacks to download certificates (as a neighboring answer advices) because that's fundamentally insecure and may compromise the system.

Second, you need to tell wget where your certificates are, since it doesn't pick them up by default in Cygwin environment. If you can do that either with the command-line parameter --ca-directory=/usr/ssl/certs (best for shell scripts) or by adding ca_directory = /usr/ssl/certs to ~/.wgetrc file.

You can also fix that by running ln -sT /usr/ssl /etc/ssl as pointed out in another answer, but that will work only if you have administrative access to the system. Other solutions I described do not require that.

In Java I used encoding "IBM850" to write the file. That solved the problem.

When using sonar-scanner for swift, use sonar.coverage.exclusions in your sonar-project.properties to exclude any file for only code coverage. If you want to exclude files from analysis as well, you can use sonar.exclusions. This has worked for me in swift

sonar.coverage.exclusions=**/*ViewController.swift,**/*Cell.swift,**/*View.swift

With jquery library

<button onclick="$('.inputFile').click();">Select File ...</button>
<input class="inputFile" type="file" style="display: none;">

Yep, Use a better option source filter. If you're searching with JSON it'll look something like this:

{
    "_source": ["user", "message", ...],
    "query": ...,
    "size": ...
}

In ES 2.4 and earlier, you could also use the fields option to the search API:

{
    "fields": ["user", "message", ...],
    "query": ...,
    "size": ...
}

This is deprecated in ES 5+. And source filters are more powerful anyway!

In general, ! is a perfectly good and readable boolean logic operator. No reason not to use it unless you're simplifying by removing double negatives or applying Morgan's law.

!(!A) = A

or

!(!A | !B) = A & B

As a rule of thumb, keep the signature of your boolean return methods mnemonic and in line with convention. The problem with the scenario that @hvgotcodes proposes is that of course a.b and c.d.e are not very friendly examples to begin with. Suppose you have a Flight and a Seat class for a flight booking application. Then the condition for booking a flight could perfectly be something like

if(flight.isActive() && !seat.isTaken())
{
    //book the seat
}

This perfectly readable and understandable code. You could re-define your boolean logic for the Seat class and rephrase the condition to this, though.

if(flight.isActive() && seat.isVacant())
{
    //book the seat
}

Thus removing the ! operator if it really bothers you, but you'll see that it all depends on what your boolean methods mean.

If you need the context of A in B, you need to pass it to B, and you can do that by passing the Activity A as parameter as others suggested. I do not see much the problem of having the many instances of A having their own pointers to B, not sure if that would even be that much of an overhead.

But if that is the problem, a possibility is to keep the pointer to A as a sort of global, avariable of the Application class, as @hasanghaforian suggested. In fact, depending on what do you need the context for, you could even use the context of the Application instead.

I'd suggest reading this article about context to better figure it out what context you need.

I wouldn't call those different kind of streams. The Stream class have CanRead and CanWrite properties that tell you if the particular stream can be read from and written to.

The major difference between different stream classes (such as MemoryStream vs FileStream) is the backing store - where the data is read from or where it's written to. It's kind of obvious from the name. A MemoryStream stores the data in memory only, a FileStream is backed by a file on disk, a NetworkStream reads data from the network and so on.

Do I even need a for loop to create a list?

No, you can (and in general circumstances should) use the built-in function range():

>>> range(1,5)
[1, 2, 3, 4]

i.e.

def naturalNumbers(n):
    return range(1, n + 1)

Python 3's range() is slightly different in that it returns a range object and not a list, so if you're using 3.x wrap it all in list(): list(range(1, n + 1)).

In iOS8 sizeWithFont has been deprecated, please refer to

CGSize yourLabelSize = [yourLabel.text sizeWithAttributes:@{NSFontAttributeName : [UIFont fontWithName:yourLabel.font size:yourLabel.fontSize]}];

You can add all the attributes you want in sizeWithAttributes. Other attributes you can set:

- NSForegroundColorAttributeName
- NSParagraphStyleAttributeName
- NSBackgroundColorAttributeName
- NSShadowAttributeName

and so on. But probably you won't need the others

You could write a User Defined Function that returns the min date value like this:

select cast(-53690 as datetime)

Then use that function in your scripts, and if you ever need to change it, there is only one place to do that.

Alternately, you could use this query if you prefer it for better readability:

select cast('1753-1-1' as datetime)

Example Function

create function dbo.DateTimeMinValue()
returns datetime as
begin
    return (select cast(-53690 as datetime))
end

Usage

select dbo.DateTimeMinValue() as DateTimeMinValue

DateTimeMinValue
-----------------------
1753-01-01 00:00:00.000

If you want to make a change global to the whole notebook:

import matplotlib.pyplot as plt
%matplotlib inline
plt.rcParams["figure.figsize"] = [10, 5]

There should be a script named mvim in the root of the .bz2 file. Copy this somewhere into your $PATH ( /usr/local/bin would be good ) and you should be sorted.

A little late, but if any of you have been going crazy trying to use inline SVG as a background, the escaping suggestions above do not quite work. For one, it does not work in IE, and depending on the content of your SVG the technique will cause trouble in other browsers, like FF.

If you base64 encode the svg (not the entire url, just the svg tag and its contents! ) it works in all browsers. Here is the same jsfiddle example in base64: http://jsfiddle.net/vPA9z/3/

The CSS now looks like this:

body { background-image: 
    url("data:image/svg+xml;base64,PHN2ZyB4bWxucz0naHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmcnIHdpZHRoPScxMCcgaGVpZ2h0PScxMCc+PGxpbmVhckdyYWRpZW50IGlkPSdncmFkaWVudCc+PHN0b3Agb2Zmc2V0PScxMCUnIHN0b3AtY29sb3I9JyNGMDAnLz48c3RvcCBvZmZzZXQ9JzkwJScgc3RvcC1jb2xvcj0nI2ZjYycvPiA8L2xpbmVhckdyYWRpZW50PjxyZWN0IGZpbGw9J3VybCgjZ3JhZGllbnQpJyB4PScwJyB5PScwJyB3aWR0aD0nMTAwJScgaGVpZ2h0PScxMDAlJy8+PC9zdmc+");

Remember to remove any URL escaping before converting to base64. In other words, the above example showed color='#fcc' converted to color='%23fcc', you should go back to #.

The reason why base64 works better is that it eliminates all the issues with single and double quotes and url escaping

If you are using JS, you can use window.btoa() to produce your base64 svg; and if it doesn't work (it might complain about invalid characters in the string), you can simply use https://www.base64encode.org/.

Example to set a div background:

var mySVG = "<svg xmlns='http://www.w3.org/2000/svg' width='10' height='10'><linearGradient id='gradient'><stop offset='10%' stop-color='#F00'/><stop offset='90%' stop-color='#fcc'/> </linearGradient><rect fill='url(#gradient)' x='0' y='0' width='100%' height='100%'/></svg>";_x000D_
var mySVG64 = window.btoa(mySVG);_x000D_
document.getElementById('myDiv').style.backgroundImage = "url('data:image/svg+xml;base64," + mySVG64 + "')";

html, body, #myDiv {_x000D_
  width: 100%;_x000D_
  height: 100%;_x000D_
  margin: 0;_x000D_
}

<div id="myDiv"></div>

With JS you can generate SVGs on the fly, even changing its parameters.

One of the better articles on using SVG is here : http://dbushell.com/2013/02/04/a-primer-to-front-end-svg-hacking/

Hope this helps

Err.. If you are a git noob are you sure you have git commit before git push? I made this mistake the first time!

Following is a Java-Spark way to do it , 1) add a sequentially increment columns. 2) Select Row number using Id. 3) Drop the Column

import static org.apache.spark.sql.functions.*;
..

ds = ds.withColumn("rownum", functions.monotonically_increasing_id());
ds = ds.filter(col("rownum").equalTo(99));
ds = ds.drop("rownum");

N.B. monotonically_increasing_id starts from 0;

Best way is to have a contextual action bar with listview on multiselect, You can make listview as multiselect using the following code

listview.setChoiceMode(AbsListView.CHOICE_MODE_MULTIPLE_MODAL);

And now set multichoice listener for Listview ,You can see the complete implementation of multiselect listview at Android multi select listview

In java8, I would use the Instant class which is already in UTC and is convenient to work with.

import java.time.Instant;

Instant ins = Instant.now();
long ts = ins.toEpochMilli();

Instant ins2 = Instant.ofEpochMilli(ts)

Alternatively, you can use the following:

import java.time.*;

Instant ins = Instant.now(); 

OffsetDateTime odt = ins.atOffset(ZoneOffset.UTC);
ZonedDateTime zdt = ins.atZone(ZoneId.of("UTC"));

Back to Instant

Instant ins4 = Instant.from(odt);

Hey, What you can do is apply a fixed width to both the containers and then use another div class where clear:both, like

div#left {

width: 600px;
float: left;
}

div#right {

width: 240px;
float: right;

}

div.clear {

clear:both;

}

place a the clear div under left and right container.

Make sure that both projects have same target framework version here: right click on project -> properties -> application (tab) -> target framework

Also, make sure that the project "logger" (which you want to include in the main project) has the output type "Class Library" in: right click on project -> properties -> application (tab) -> output type

Finally, Rebuild the solution.

You can check scrollHeight and clientHeight with scrollTop to scroll to bottom of div like code below.

$('#div').scroll(function (event) {_x000D_
  if ((parseInt($('#div')[0].scrollHeight) - parseInt(this.clientHeight)) == parseInt($('#div').scrollTop())) _x000D_
  {_x000D_
    console.log("this is scroll bottom of div");_x000D_
  }_x000D_
  _x000D_
});

You can use this regex:

[^\w \xC0-\xFF]

Case ask, the options is Multiline.

[Updated to use modern C# as per @sblom's suggestion]

I had this problem and I ended up with this (after all, an if and 2 returns is soo long-winded!):

int? ToNullableInt (string val)
    => int.TryParse (val, out var i) ? (int?) i : null;

On a more serious note, try not to mix int, which is a C# keyword, with Int32, which is a .NET Framework BCL type - although it works, it just makes code look messy.

I'm in agreement that using Dictionary is better running time performance then nested for loops (O(n) vs O(n^2)). However to address OP, here is a solution where a HashSet is used to prevent repeating the counting of integers already counted, such as integer 5 in example array.

static void Main(string[] args)
{              
    int[] A = { 10, 5, 10, 2, 2, 3, 4, 5, 5, 6, 7, 8, 9, 11, 12, 12 };

    var set = new HashSet<int>();
    for (int i = 0; i < A.Length - 1; i++) {
        int count = 0;
        for (int j = i; j < A.Length - 1; j++) {
            if (A[i] == A[j + 1] && !set.Contains(A[i]))
                count++;
        }
        set.Add(A[i]);
        if (count > 0) {
            Console.WriteLine("{0} occurs {1} times", A[i], count + 1);
            Console.ReadKey();
        }
    }
}

Unfortunately MySQL does not feature a split string function. However you can create a user defined function for this, such as the one described in the following article:

• MySQL Split String Function by Federico Cargnelutti

With that function:

DELIMITER $$

CREATE FUNCTION SPLIT_STR(
  x VARCHAR(255),
  delim VARCHAR(12),
  pos INT
)
RETURNS VARCHAR(255) DETERMINISTIC
BEGIN 
    RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(x, delim, pos),
       LENGTH(SUBSTRING_INDEX(x, delim, pos -1)) + 1),
       delim, '');
END$$

DELIMITER ;

you would be able to build your query as follows:

SELECT SPLIT_STR(membername, ' ', 1) as memberfirst,
       SPLIT_STR(membername, ' ', 2) as memberlast
FROM   users;

If you prefer not to use a user defined function and you do not mind the query to be a bit more verbose, you can also do the following:

SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(membername, ' ', 1), ' ', -1) as memberfirst,
       SUBSTRING_INDEX(SUBSTRING_INDEX(membername, ' ', 2), ' ', -1) as memberlast
FROM   users;

Try this:

subset(studentdata, Drink=='water')

that should do it.

for German Layout (Deutsches Layout) the default is:

for line Comment: strg + Numpad(/)

for block Comment: strg+shift+Numpad(/)

Of course "cache-breaking" techniques will get the job done, but this would not happen in the first place if the server indicated to the client that the response should not be cached. In some cases it is beneficial to cache responses, some times not. Let the server decide the correct lifetime of the data. You may want to change it later. Much easier to do from the server than from many different places in your UI code.

Of course this doesn't help if you have no control over the server.

dacite may also be a solution for you, it supports following features:

• nested structures
• (basic) types checking
• optional fields (i.e. typing.Optional)
• unions
• forward references
• collections
• custom type hooks

https://pypi.org/project/dacite/

from dataclasses import dataclass
from dacite import from_dict


@dataclass
class User:
    name: str
    age: int
    is_active: bool


data = {
    'name': 'John',
    'age': 30,
    'is_active': True,
}

user = from_dict(data_class=User, data=data)

assert user == User(name='John', age=30, is_active=True)

After using hg update -r REV it wasn't clear in the answer about how to commit that change so that you can then push.

If you just try to commit after the update, Mercurial doesn't think there are any changes.

I had to first make a change to any file (say in a README) so Mercurial recognized that I made a new change, then I could commit that.

This then created two heads as mentioned.

To get rid of the other head before pushing, I then followed the No-Op Merges step to remedy that situation.

I was then able to push.

Create a Batch file (.bat) in Windows with the following command in it:

%ANDROID_HOME%\tools\bin\sdkmanager.bat --list && pause

NOTE: Using && pause is necessary to be able to review the information, once it is listed. If not used, the batch file will simply run, show the information in just mere few seconds and exit right away.

Why not use properly formulated geospatial queries???

Here is the SQL server reference page on the STContains geospatial function:

https://docs.microsoft.com/en-us/sql/t-sql/spatial-geography/stcontains-geography-data-type?view=sql-server-ver15

or if you do not waant to use box and radian conversion , you cna always use the distance function to find the points that you need:

DECLARE @CurrentLocation geography; 
SET @CurrentLocation  = geography::Point(12.822222, 80.222222, 4326)

SELECT * , Round (GeoLocation.STDistance(@CurrentLocation ),0) AS Distance FROM [Landmark]
WHERE GeoLocation.STDistance(@CurrentLocation )<= 2000 -- 2 Km

There should be similar functionality for almost any database out there.

If you have implemented geospatial indexing correctly your searches would be way faster than the approach you are using

A method without any dependency and takes care of .. , . and duplicate separators.

public static String getFileName(String filePath) {
    if( filePath==null || filePath.length()==0 )
        return "";
    filePath = filePath.replaceAll("[/\\\\]+", "/");
    int len = filePath.length(),
        upCount = 0;
    while( len>0 ) {
        //remove trailing separator
        if( filePath.charAt(len-1)=='/' ) {
            len--;
            if( len==0 )
                return "";
        }
        int lastInd = filePath.lastIndexOf('/', len-1);
        String fileName = filePath.substring(lastInd+1, len);
        if( fileName.equals(".") ) {
            len--;
        }
        else if( fileName.equals("..") ) {
            len -= 2;
            upCount++;
        }
        else {
            if( upCount==0 )
                return fileName;
            upCount--;
            len -= fileName.length();
        }
    }
    return "";
}

Test case:

@Test
public void testGetFileName() {
    assertEquals("", getFileName("/"));
    assertEquals("", getFileName("////"));
    assertEquals("", getFileName("//C//.//../"));
    assertEquals("", getFileName("C//.//../"));
    assertEquals("C", getFileName("C"));
    assertEquals("C", getFileName("/C"));
    assertEquals("C", getFileName("/C/"));
    assertEquals("C", getFileName("//C//"));
    assertEquals("C", getFileName("/A/B/C/"));
    assertEquals("C", getFileName("/A/B/C"));
    assertEquals("C", getFileName("/C/./B/../"));
    assertEquals("C", getFileName("//C//./B//..///"));
    assertEquals("user", getFileName("/user/java/.."));
    assertEquals("C:", getFileName("C:"));
    assertEquals("C:", getFileName("/C:"));
    assertEquals("java", getFileName("C:\\Program Files (x86)\\java\\bin\\.."));
    assertEquals("C.ext", getFileName("/A/B/C.ext"));
    assertEquals("C.ext", getFileName("C.ext"));
}

Maybe getFileName is a bit confusing, because it returns directory names also. It returns the name of file or last directory in a path.

Highlight "B1" and press F4. This will lock the cell.

Now you can drag it around and it will not change. The principle is simple. It adds a dollar sign before both coordinates. A dollar sign in front of a coordinate will lock it when you copy the formula around. You can have partially locked coordinates and fully locked coordinates.

Here is the implementation of custom filter, which will filter the data using array of values.It will support multiple key object with both array and single value of keys. As mentioned inangularJS API AngularJS filter Doc supports multiple key filter with single value, but below custom filter will support same feature as angularJS and also supports array of values and combination of both array and single value of keys.Please find the code snippet below,

myApp.filter('filterMultiple',['$filter',function ($filter) {
return function (items, keyObj) {
    var filterObj = {
        data:items,
        filteredData:[],
        applyFilter : function(obj,key){
            var fData = [];
            if (this.filteredData.length == 0)
                this.filteredData = this.data;
            if (obj){
                var fObj = {};
                if (!angular.isArray(obj)){
                    fObj[key] = obj;
                    fData = fData.concat($filter('filter')(this.filteredData,fObj));
                } else if (angular.isArray(obj)){
                    if (obj.length > 0){
                        for (var i=0;i<obj.length;i++){
                            if (angular.isDefined(obj[i])){
                                fObj[key] = obj[i];
                                fData = fData.concat($filter('filter')(this.filteredData,fObj));    
                            }
                        }

                    }
                }
                if (fData.length > 0){
                    this.filteredData = fData;
                }
            }
        }
    };
    if (keyObj){
        angular.forEach(keyObj,function(obj,key){
            filterObj.applyFilter(obj,key);
        });
    }
    return filterObj.filteredData;
}
}]);

Usage:

arrayOfObjectswithKeys | filterMultiple:{key1:['value1','value2','value3',...etc],key2:'value4',key3:[value5,value6,...etc]}

Here is a fiddle example with implementation of above "filterMutiple" custom filter. :::Fiddle Example:::

RC's post was SUPER useful. I never thought about using the $(dir $@) function, but it did exactly what I needed it to do.

In parentDir, have a bunch of directories with source files in them: dirA, dirB, dirC. Various files depend on the object files in other directories, so I wanted to be able to make one file from within one directory, and have it make that dependency by calling the makefile associated with that dependency.

Essentially, I made one Makefile in parentDir that had (among many other things) a generic rule similar to RC's:

%.o : %.cpp
        @mkdir -p $(dir $@)
        @echo "============="
        @echo "Compiling $<"
        @$(CC) $(CFLAGS) -c $< -o $@

Each subdirectory included this upper-level makefile in order to inherit this generic rule. In each subdirectory's Makefile, I wrote a custom rule for each file so that I could keep track of everything that each individual file depended on.

Whenever I needed to make a file, I used (essentially) this rule to recursively make any/all dependencies. Perfect!

NOTE: there's a utility called "makepp" that seems to do this very task even more intuitively, but for the sake of portability and not depending on another tool, I chose to do it this way.

Hope this helps!

This is not a bug- you can only transition on ordinal/calculable properties (an easy way of thinking of this is any property with a numeric start and end number value..though there are a few exceptions).

This is because transitions work by calculating keyframes between two values, and producing an animation by extrapolating intermediate amounts.

visibility in this case is a binary setting (visible/hidden), so once the transition duration elapses, the property simply switches state, you see this as a delay- but it can actually be seen as the final keyframe of the transition animation, with the intermediary keyframes not having been calculated (what constitutes the values between hidden/visible? Opacity? Dimension? As it is not explicit, they are not calculated).

opacity is a value setting (0-1), so keyframes can be calculated across the duration provided.

A list of transitionable (animatable) properties can be found here

The <colgroup> and <col> tags that lives inside tables are designed for this purpose. If you have three columns in your table and want to align the third, add this after your opening <table> tag:

 <colgroup>
     <col />
     <col />
     <col class="your-right-align-class" />
 </colgroup>

along with the requisite CSS:

 .your-right-align-class { text-align: right; }

From the W3:

Definition and Usage

• The <col> tag defines attribute values for one or more columns in a table.

• The <col> tag is useful for applying styles to entire columns, instead of repeating the styles for each cell, for each row.

 $('#results').on('click', '.item', function () {
                    var NestId = $(this).data('id');
                   // var url = '@Url.Action("Details", "Artists",new { NestId = '+NestId+'  })'; 
                    var url = '@ Url.Content("~/Artists/Details?NestId =' + NestId + '")'
                    window.location.href = url; 
                })

my_string.replaceAll("\\p{C}", "?");

See more about Unicode regex. java.util.regexPattern/String.replaceAll supports them.

If 'config/config.json' file is used then add 'logging': false to the config.json in this case under development configuration section.

  // file config/config.json
  {
      {
      "development": {
        "username": "username",
        "password": "password",
        "database": "db_name",
        "host": "127.0.0.1",
        "dialect": "mysql",
        "logging": false
      },
      "test": {
    ...
   }

Use the ampersand just like you would from the shell.

#!/usr/bin/bash
function_to_fork() {
   ...
}

function_to_fork &
# ... execution continues in parent process ...

Querying across 2 different databases is a distributed query. Here is a list of some techniques plus the pros and cons:

1. Linked servers: Provide access to a wider variety of data sources than SQL Server replication provides
2. Linked servers: Connect with data sources that replication does not support or which require ad hoc access
3. Linked servers: Perform better than OPENDATASOURCE or OPENROWSET
4. OPENDATASOURCE and OPENROWSET functions: Convenient for retrieving data from data sources on an ad hoc basis. OPENROWSET has BULK facilities as well that may/may not require a format file which might be fiddley
5. OPENQUERY: Doesn't support variables
6. All are T-SQL solutions. Relatively easy to implement and set up
7. All are dependent on connection between source and destionation which might affect performance and scalability

Push a new page onto the stack, then remove the current page. This results in a switch.

item.Tapped += async (sender, e) => {
    await Navigation.PushAsync (new SecondPage ());
    Navigation.RemovePage(this);
};

You need to be in a Navigation Page first:

MainPage = NavigationPage(new FirstPage());

Switching content isn't ideal as you have just one big page and one set of page events like OnAppearing ect.

Then run:

ssh-keyscan -t rsa bitbucket.org >>~/.ssh/known_hosts
python --win known_hosts.py >known_hosts.reg
start known_hosts.reg

And choose to import into the registry. The keyscan will retrieve the public key for the domain (I had my problems with bitbucket), and then the python script will convert it to Plink format.

On Windows Start Menu, right click on Command Prompt.

Click on "Properties".

"Command Prompt Properties" dialog box opens.

Edit the field "Start in " to a location where you want to start the command prompt.

Example: Chand %HOMEDRIVE%%HOMEPATH% to D:\PersonalPrograms.

Next time when you start command prompt the start up directory will be D:\PersonalPrograms

You can create your own cursors and set them as the cursor using cursor: url('path-to-your-cursor');, or find Firefox's and copy them (bonus: a nice consistent look in every browser).

According to the docs, there were several changes to the USB power management from kernels 2.6.32, which seem to settle in 2.6.38. Now you'll need to wait for the device to become idle, which is governed by the particular device driver. The driver needs to support it, otherwise the device will never reach this state. Unluckily, now the user has no chance to force this. However, if you're lucky and your device can become idle, then to turn this off you need to:

echo "0" > "/sys/bus/usb/devices/usbX/power/autosuspend"
echo "auto" > "/sys/bus/usb/devices/usbX/power/level"

or, for kernels around 2.6.38 and above:

echo "0" > "/sys/bus/usb/devices/usbX/power/autosuspend_delay_ms"
echo "auto" > "/sys/bus/usb/devices/usbX/power/control"

This literally means, go suspend at the moment the device becomes idle.

So unless your fan is something "intelligent" that can be seen as a device and controlled by a driver, you probably won't have much luck on current kernels.

The excellent joda-time library is almost always a better choice than Java's Date or Calendar classes. Here's a few examples:

DateTime aDate = new DateTime(year, month, day, hour, minute, second);
DateTime anotherDate = new DateTime(anotherYear, anotherMonth, anotherDay, ...);
if (aDate.isAfter(anotherDate)) {...}
DateTime yearFromADate = aDate.plusYears(1);

Have you tried it?

If you do:

var HI = 'Hello World';

In global.js. And then do:

alert(HI);

In js1.js it will alert it fine. You just have to include global.js prior to the rest in the HTML document.

The only catch is that you have to declare it in the window's scope (not inside any functions).

You could just nix the var part and create them that way, but it's not good practice.

Simply use

int len=str.length();

.NET has changed since many of these answers were posted, and I'd like to provide a more up-to-date answer. Use an async method to start a Task that will run on a background thread:

private async Task<String> MakeRequestAsync(String url)
{    
    String responseText = await Task.Run(() =>
    {
        try
        {
            HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
            WebResponse response = request.GetResponse();            
            Stream responseStream = response.GetResponseStream();
            return new StreamReader(responseStream).ReadToEnd();            
        }
        catch (Exception e)
        {
            Console.WriteLine("Error: " + e.Message);
        }
        return null;
    });

    return responseText;
}

To use the async method:

String response = await MakeRequestAsync("http://example.com/");

Update:

This solution does not work for UWP apps which use WebRequest.GetResponseAsync() instead of WebRequest.GetResponse(), and it does not call the Dispose() methods where appropriate. @dragansr has a good alternative solution that addresses these issues.

jnettop is another candidate.

edit: it only shows the streams, not the owner processes.

Perhaps use plt.annotate:

import numpy as np
import matplotlib.pyplot as plt

N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]

plt.subplots_adjust(bottom = 0.1)
plt.scatter(
    data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
    cmap=plt.get_cmap('Spectral'))

for label, x, y in zip(labels, data[:, 0], data[:, 1]):
    plt.annotate(
        label,
        xy=(x, y), xytext=(-20, 20),
        textcoords='offset points', ha='right', va='bottom',
        bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
        arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))

plt.show()

Though I would give an update using the new composition api.

Component

<template>
  <div @mouseenter="hovering = true" @mouseleave="hovering = false">
    {{ hovering }}
  </div>
</template>

<script>
  import { ref } from '@vue/compsosition-api'

  export default {
    setup() {
      const hovering = ref(false)
      return { hovering }
    }
  })
</script>

Reusable Composition Function

Creating a useHover function will allow you to reuse in any components.

export function useHover(target: Ref<HTMLElement | null>) {
  const hovering = ref(false)

  const enterHandler = () => (hovering.value = true)
  const leaveHandler = () => (hovering.value = false)

  onMounted(() => {
    if (!target.value) return
    target.value.addEventListener('mouseenter', enterHandler)
    target.value.addEventListener('mouseleave', leaveHandler)
  })

  onUnmounted(() => {
    if (!target.value) return
    target.value.removeEventListener('mouseenter', enterHandler)
    target.value.removeEventListener('mouseleave', leaveHandler)
  })

  return hovering
}

Here's a quick example calling the function inside a Vue component.

<template>
  <div ref="hoverRef">
    {{ hovering }}
  </div>
</template>

<script lang="ts">
  import { ref } from '@vue/compsosition-api'
  import { useHover } from './useHover'

  export default {
    setup() {
      const hoverRef = ref(null)
      const hovering = useHover(hoverRef)
      return { hovering, hoverRef }
    }
  })
</script>

You can also use a library such as @vuehooks/core which comes with many useful functions including useHover.

I have just tried to install that extension on my dev server.

First, make sure that the extension is correctly enabled. Your phpinfo() output doesn't seem complete.

If it is indeed installed properly, your phpinfo() should have a section that looks like this:

If you do not get that section in your phpinfo(). Make sure that you are using the right version. There are both non-thread-safe and thread-safe versions of the extension.

Finally, check your extension_dir setting. By default it's this: extension_dir = "ext", for most of the time it works fine, but if it doesn't try: extension_dir = "C:\PHP\ext".

===========================================================================

EDIT given new info:

You are using the wrong function. mssql_connect() is part of the Mssql extension. You are using microsoft's extension, so use sqlsrv_connect(), for the API for the microsoft driver, look at SQLSRV_Help.chm which should be extracted to your ext directory when you extracted the extension.

Try:

SELECT * FROM information_schema.statistics 
  WHERE table_schema = [DATABASE NAME] 
    AND table_name = [TABLE NAME] AND column_name = [COLUMN NAME]

It will tell you if there is an index of any kind on a certain column without the need to know the name given to the index. It will also work in a stored procedure (as opposed to show index)

for (const field in this.formErrors) {
  if (this.formErrors.hasOwnProperty(field)) {

for (const key in control.errors) {
  if (control.errors.hasOwnProperty(key)) {

As promised, I'm putting an example for how to use annotations to serialize/deserialize polymorphic objects, I based this example in the Animal class from the tutorial you were reading.

First of all your Animal class with the Json Annotations for the subclasses.

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonSubTypes;
import com.fasterxml.jackson.annotation.JsonTypeInfo;

@JsonIgnoreProperties(ignoreUnknown = true)
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY)
@JsonSubTypes({
    @JsonSubTypes.Type(value = Dog.class, name = "Dog"),

    @JsonSubTypes.Type(value = Cat.class, name = "Cat") }
)
public abstract class Animal {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

Then your subclasses, Dog and Cat.

public class Dog extends Animal {

    private String breed;

    public Dog() {

    }

    public Dog(String name, String breed) {
        setName(name);
        setBreed(breed);
    }

    public String getBreed() {
        return breed;
    }

    public void setBreed(String breed) {
        this.breed = breed;
    }
}

public class Cat extends Animal {

    public String getFavoriteToy() {
        return favoriteToy;
    }

    public Cat() {}

    public Cat(String name, String favoriteToy) {
        setName(name);
        setFavoriteToy(favoriteToy);
    }

    public void setFavoriteToy(String favoriteToy) {
        this.favoriteToy = favoriteToy;
    }

    private String favoriteToy;

}

As you can see, there is nothing special for Cat and Dog, the only one that know about them is the abstract class Animal, so when deserializing, you'll target to Animal and the ObjectMapper will return the actual instance as you can see in the following test:

public class Test {

    public static void main(String[] args) {

        ObjectMapper objectMapper = new ObjectMapper();

        Animal myDog = new Dog("ruffus","english shepherd");

        Animal myCat = new Cat("goya", "mice");

        try {
            String dogJson = objectMapper.writeValueAsString(myDog);

            System.out.println(dogJson);

            Animal deserializedDog = objectMapper.readValue(dogJson, Animal.class);

            System.out.println("Deserialized dogJson Class: " + deserializedDog.getClass().getSimpleName());

            String catJson = objectMapper.writeValueAsString(myCat);

            Animal deseriliazedCat = objectMapper.readValue(catJson, Animal.class);

            System.out.println("Deserialized catJson Class: " + deseriliazedCat.getClass().getSimpleName());



        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

Output after running the Test class:

{"@type":"Dog","name":"ruffus","breed":"english shepherd"}

Deserialized dogJson Class: Dog

{"@type":"Cat","name":"goya","favoriteToy":"mice"}

Deserialized catJson Class: Cat

Hope this helps,

You cannot open and read a directory, use the isFile() and isDirectory() methods to distinguish between files and folders. You can get the contents of folders using the list() and listFiles() methods (for filenames and Files respectively) you can also specify a filter that selects a subset of files listed.

def f(x) -> str:
return x+4

print(f(45))

# will give the result : 
49

# or with other words '-> str' has NO effect to return type:

print(f(45).__class__)

<class 'int'>

You can always add a Relative layout or a Linear Layout in your Toolbar and place a Image view for back icon or close icon anywhere in toolbar as you like

For example I have used Relative layout in my toolbar

 <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar_top"
                android:layout_width="match_parent"
                android:layout_height="35dp"
                android:minHeight="?attr/actionBarSize"
                android:nextFocusDown="@id/netflixVideoGridView"
                app:layout_collapseMode="pin">

                <RelativeLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content">


                    <TextView

                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:text="Myflix"
                        android:textAllCaps="true"
                        android:textSize="19sp"
                        android:textColor="@color/red"
                        android:textStyle="bold" />


                    <ImageView
                        android:id="@+id/closeMyFlix"
                        android:layout_alignParentRight="true"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_gravity="center_vertical"
                        app:srcCompat="@drawable/vector_close" />


                </RelativeLayout>

            </android.support.v7.widget.Toolbar>

And it looks like this:

You can add click listener on that image view from Activity or fragment like this.

  closeMyFlix.setOnClickListener({
            Navigator.instance.showFireTV(  activity!!.supportFragmentManager)
        })

On *nix, unlike Windows, the current directory is usually not in your $PATH variable. So the current directory is not searched when executing commands. You don't need ./ for running applications because these applications are in your $PATH; most likely they are in /bin or /usr/bin.

This is the simplest solution I guess :

function diffArray(arr1, arr2) {
  return arr1
    .concat(arr2)
    .filter(item => !arr1.includes(item) || !arr2.includes(item));
}

x=[1,2,3,4,5]
sum=0
for s in range(0,len(x)):
   sum=sum+x[s]
print sum   

Just use this code

QPixmap pixmap("path_to_icon");
QIcon iconBack(pixmap);

Note that:"path_to_icon" is the path of image icon in file .qrc of your project You can find how to add .qrc file here

No one seems to have answered this correctly yet. I'll paste my solution here in case anyone needs it. The following code works regardless if first day of the week is a monday or a sunday or something else.

public static class DateTimeExtension
{
  public static DateTime GetFirstDayOfThisWeek(this DateTime d)
  {
    CultureInfo ci = System.Threading.Thread.CurrentThread.CurrentCulture;
    var first = (int)ci.DateTimeFormat.FirstDayOfWeek;
    var current = (int)d.DayOfWeek;

    var result = first <= current ?
      d.AddDays(-1 * (current - first)) :
      d.AddDays(first - current - 7);

    return result;
  }
}

class Program
{
  static void Main()
  {
    System.Threading.Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo("en-US");
    Console.WriteLine("Current culture set to en-US");
    RunTests();
    Console.WriteLine();
    System.Threading.Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo("da-DK");
    Console.WriteLine("Current culture set to da-DK");
    RunTests();
    Console.ReadLine();
  }

  static void RunTests()
  {
    Console.WriteLine("Today {1}: {0}", DateTime.Today.Date.GetFirstDayOfThisWeek(), DateTime.Today.Date.ToString("yyyy-MM-dd"));
    Console.WriteLine("Saturday 2013-03-02: {0}", new DateTime(2013, 3, 2).GetFirstDayOfThisWeek());
    Console.WriteLine("Sunday 2013-03-03: {0}", new DateTime(2013, 3, 3).GetFirstDayOfThisWeek());
    Console.WriteLine("Monday 2013-03-04: {0}", new DateTime(2013, 3, 4).GetFirstDayOfThisWeek());
  }
}

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"/> 

This function generates random string consisting of upper,lowercase letters, digits, pass the length seperator, no_of_blocks to specify your string format

eg: len_sep = 4, no_of_blocks = 4 will generate the following pattern,

F4nQ-Vh5z-JKEC-WhuS

Where, length seperator will add "-" after 4 characters

XXXX-

no of blocks will generate the following patten of characters as string

XXXX - XXXX - XXXX - XXXX

if a single random string is needed, just keep the no_of_blocks variable to be equal to 1 and len_sep to specify the length of the random string.

eg: len_sep = 10, no_of_blocks = 1, will generate the following pattern ie. random string of length 10,

F01xgCdoDU

import random as r

def generate_random_string(len_sep, no_of_blocks):
    random_string = ''
    random_str_seq = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
    for i in range(0,len_sep*no_of_blocks):
        if i % len_sep == 0 and i != 0:
            random_string += '-'
        random_string += str(random_str_seq[r.randint(0, len(random_str_seq) - 1)])
    return random_string

I created this method, it is ideal because it aborts the connection without downloading it in its entirety, ideal for checking if videos or large images exist, decreasing the response time and the need to download the entire file

// if-url-exist.js v1
function ifUrlExist(url, callback) {
    let request = new XMLHttpRequest;
    request.open('GET', url, true);
    request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
    request.setRequestHeader('Accept', '*/*');
    request.onprogress = function(event) {
        let status = event.target.status;
        let statusFirstNumber = (status).toString()[0];
        switch (statusFirstNumber) {
            case '2':
                request.abort();
                return callback(true);
            default:
                request.abort();
                return callback(false);
        };
    };
    request.send('');
};

Example of use:

ifUrlExist(url, function(exists) {
    console.log(exists);
});

Don't do: mkdir -m 777 -p a/b/c since that will only set permission 777 on the last directory, c; a and b will be created with the default permission from your umask.

Instead to create any new directories with permission 777, run mkdir -p in a subshell where you override the umask:

(umask u=rwx,g=rwx,o=rwx && mkdir -p a/b/c)

Note that this won't change the permissions if any of a, b and c already exist though.

try using Pretty Dump it works great for me

As of June 2020, adding role='button' to any HTML tag would add cursor: "pointer" to the element styling.

<span role="button">Non-button element button</span>

Official discussion on this feature - https://github.com/twbs/bootstrap/issues/23709

Remember that Raspberry Pi does not have real time clock. So even you are connected to internet have to set the time every time you power on or restart.

This is how it works:

1. Type sudo raspi-config in the Raspberry Pi command line
2. Internationalization options
3. Change Time Zone
4. Select geographical area
5. Select city or region
6. Reboot your pi

Next thing you can set time using this command

sudo date -s "Mon Aug  12 20:14:11 UTC 2014"

More about data and time

man date

When Pi is connected to computer should have to manually set data and time

Here is code snippet demo how to get screen orientation was recommend by hackbod and Martijn:

? Trigger when change Orientation:

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
        int nCurrentOrientation = _getScreenOrientation();
    _doSomeThingWhenChangeOrientation(nCurrentOrientation);
}

? Get current orientation as hackbod recommend:

private int _getScreenOrientation(){    
    return getResources().getConfiguration().orientation;
}

?There are alternative solution for get current screen orientation ? follow Martijn solution:

private int _getScreenOrientation(){
        Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
        return display.getOrientation();
}

?Note: I was try both implement ? & ?, but on RealDevice (NexusOne SDK 2.3) Orientation it returns the wrong orientation.

?So i recommend to used solution ? to get Screen orientation which have more advantage: clearly, simple and work like a charm.

?Check carefully return of orientation to ensure correct as our expected (May be have limited depend on physical devices specification)

Hope it help,

The first line of a constructor is always an invocation to another constructor. You can choose between calling a constructor from the same class with "this(...)" or a constructor from the parent clas with "super(...)". If you don't include either, the compiler includes this line for you: super();

Your use case would be :

    $ArrayCollectionOfActiveUsers = $customer->users->filter(function($user) {
                        return $user->getActive() === TRUE;
                    });

if you add ->first() you'll get only the first entry returned, which is not what you want.

@ Sjwdavies You need to put () around the variable you pass to USE. You can also shorten as in_array return's a boolean already:

    $member->getComments()->filter( function($entry) use ($idsToFilter) {
        return in_array($entry->getId(), $idsToFilter);
    });

You wrote that you do not want to migrate the old volumes. So I assume either the Dockerfile that you used to build the spencercooley/wordpress image has VOLUMEs defined or you specified them on command line with the -v switch.

You could simply start a new container which imports the volumes from the old one with the --volumes-from switch like:

$ docker run --name my-new-wordpress --volumes-from my-wordpress -e VIRTUAL_HOST=domain.com --link my-mysql:mysql -d spencercooley/wordpres

So you will have a fresh container but you do not loose the old data. You do not even need to touch or migrate it.

A well-done container is always stateless. That means its process is supposed to add or modify only files on defined volumes. That can be verified with a simple docker diff <containerId> after the container ran a while.

In that case it is not dangerous when you re-create the container with the same parameters (in your case slightly modified ones). Assuming you create it from exactly the same image from which the old one was created and you re-use the same volumes with the above mentioned switch.

After the new container has started successfully and you verified that everything runs correctly you can delete the old wordpress container. The old volumes are then referred from the new container and will not be deleted.

With git there is a https format

This format accepts User + password

https://bot-user:[email protected]/equivalent/we_demand_serverless_ruby.git

So what you can do is create a new user that will be used just as a bot, add only enough permissions that he can just read the repository you want to load in NPM modules and just have that directly in your packages.json

 Github > Click on Profile > Settings > Developer settings > Personal access tokens > Generate new token

In Select Scopes part, check the on repo: Full control of private repositories

This is so that token can access private repos that user can see

Now create new group in your organization, add this user to the group and add only repositories that you expect to be pulled this way (READ ONLY permission !)

You need to be sure to push this config only to private repo

Then you can add this to your / packages.json (bot-user is name of user, xxxxxxxxx is the generated personal token)

// packages.json


{
  // ....
    "name_of_my_lib": "https://bot-user:[email protected]/ghuser/name_of_my_lib.git"
  // ...
}

First: what the others said. Forget the echo statement and just write your navbar.php as a regular HTML file.

Second: your include paths are probably messed up. To make sure you include files that are in the same directory as the current file, use __DIR__:

include __DIR__.'/navbar.php'; // PHP 5.3 and later
include dirname(__FILE__).'/navbar.php'; // PHP 5.2

Generally the practice would be to pass data as a DateTime with a "timezone" of UTC and then pass a TimeZoneInfo object and when you are ready to display the data, you use the TimeZoneInfo object to convert the UTC DateTime.

The other option is to set the DateTime with the current timezone, and then make sure the "timezone" is unknown for the DateTime object, then make sure the DateTime is again passed with a TimeZoneInfo that indicates the TimeZone of the DateTime passed.

As others have indicated here, it would be nice if Microsoft got on top of this and created one nice object to do it all, but for now you have to deal with two objects.

• 4 : DONE The operation is complete.

Using: in_array()

$search_array = array('user_from','lucky_draw_id','prize_id');

if (in_array('prize_id', $search_array)) {
    echo "The 'prize_id' element is in the array";
}

Here is output: The 'prize_id' element is in the array

Using: array_key_exists()

$search_array = array('user_from','lucky_draw_id','prize_id');

if (array_key_exists('prize_id', $search_array)) {
    echo "The 'prize_id' element is in the array";
}

No output

In conclusion, array_key_exists() does not work with a simple array. Its only to find whether an array key exist or not. Use in_array() instead.

Here is more example:

I did this combination. its work for me. but facing one issue if click move that div size is too large that scenerio scroll not down to this particular div.

 var scrollDownTo =$("#show_question_" + nQueId).position().top;
        console.log(scrollDownTo);
        $('#slider_light_box_container').animate({

You can do it with javascript, and I don't think it needs to be that fancy.

If you have a header.js file and a footer.js.

Then the contents of header.js could be something like

document.write("<div class='header'>header content</div> etc...")

Remember to escape any nested quote characters in the string you are writing. You could then call that from your static templates with

<script type="text/javascript" src="header.js"></script>

and similarly for the footer.js.

Note: I am not recommending this solution - it's a hack and has a number of drawbacks (poor for SEO and usability just for starters) - but it does meet the requirements of the questioner.

Unless somefunction is a very bad coded legacy function, you shouldn't need what you're asking.

Use multiple except clause to handle in different ways different exceptions:

try:
    someFunction()
except ValueError:
    # do something
except ZeroDivision:
    # do something else

The main point is that you shouldn't catch generic exception, but only the ones that you need to. I'm sure that you don't want to shadow unexpected errors or bugs.

The difference between text/xml and application/xml is the default character encoding if the charset parameter is omitted:

Text/xml and application/xml behave differently when the charset parameter is not explicitly specified. If the default charset (i.e., US-ASCII) for text/xml is inconvenient for some reason (e.g., bad web servers), application/xml provides an alternative (see "Optional parameters" of application/xml registration in Section 3.2).

For text/xml:

Conformant with [RFC2046], if a text/xml entity is received with the charset parameter omitted, MIME processors and XML processors MUST use the default charset value of "us-ascii"[ASCII]. In cases where the XML MIME entity is transmitted via HTTP, the default charset value is still "us-ascii".

For application/xml:

If an application/xml entity is received where the charset parameter is omitted, no information is being provided about the charset by the MIME Content-Type header. Conforming XML processors MUST follow the requirements in section 4.3.3 of [XML] that directly address this contingency. However, MIME processors that are not XML processors SHOULD NOT assume a default charset if the charset parameter is omitted from an application/xml entity.

So if the charset parameter is omitted, the character encoding of text/xml is US-ASCII while with application/xml the character encoding can be specified in the document itself.

Now a rule of thumb on the internet is: “Be strict with the output but be tolerant with the input.” That means make sure to meet the standards as much as possible when delivering data over the internet. But build in some mechanisms to overlook faults or to guess when receiving and interpreting data over the internet.

So in your case just pick one of the two types (I recommend application/xml) and make sure to specify the used character encoding properly (I recommend to use the respective default character encoding to play safe, so in case of application/xml use UTF-8 or UTF-16).

Your root logger definition is a bit confused. See the log4j documentation.

This is a standard Java properties file, which means that lines are treated as key=value pairs. Your second log4j.rootLogger line is overwriting the first, which explains why you aren't seeing anything on the console appender.

You need to merge your two rootLogger definitions into one. It looks like you're trying to have DEBUG messages go to the console and INFO messages to the file. The root logger can only have one level, so you need to change your configuration so that the appenders have appropriate levels.

While I haven't verified that this is correct, I'd guess it'll look something like this:

log4j.rootLogger=DEBUG,console,file
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.file=org.apache.log4j.RollingFileAppender

Note that you also have an error in casing - you have console lowercase in one place and in CAPS in another.

If you need this, you shouldn't use forEach, but one of the other methods available on streams; which one, depends on what your goal is.

For example, if the goal of this loop is to find the first element which matches some predicate:

Optional<SomeObject> result =
    someObjects.stream().filter(obj -> some_condition_met).findFirst();

(Note: This will not iterate the whole collection, because streams are lazily evaluated - it will stop at the first object that matches the condition).

If you just want to know if there's an element in the collection for which the condition is true, you could use anyMatch:

boolean result = someObjects.stream().anyMatch(obj -> some_condition_met);

Not quite sure why everyone is giving you a hard time for wanting to do this - there are several scenarios where you'd want a fixed size initialised list. And you've correctly deduced that arrays are sensible in these cases.

import array
verts=array.array('i',(0,)*1000)

For the non-pythonistas, the (0,)*1000 term is creating a tuple containing 1000 zeros. The comma forces python to recognise (0) as a tuple, otherwise it would be evaluated as 0.

I've used a tuple instead of a list because they are generally have lower overhead.

Here is the reason why it happens, i.e. your local directory in the host OS where you are running the docker should have the file, otherwise you get this error

One solution is to : use RUN cp <src> <dst> instead of COPY <src> <dst>

then run the command it works!

I would recommend reviewing this page on How to Write Go Code

It documents both how to structure your project in a go build friendly way, and also how to write tests. Tests do not need to be a cmd using the main package. They can simply be TestX named functions as part of each package, and then go test will discover them.

The structure suggested in that link in your question is a bit outdated, now with the release of Go 1. You no longer would need to place a pkg directory under src. The only 3 spec-related directories are the 3 in the root of your GOPATH: bin, pkg, src . Underneath src, you can simply place your project mypack, and underneath that is all of your .go files including the mypack_test.go

go build will then build into the root level pkg and bin.

So your GOPATH might look like this:

~/projects/
    bin/
    pkg/
    src/
      mypack/
        foo.go
        bar.go
        mypack_test.go

export GOPATH=$HOME/projects

$ go build mypack
$ go test mypack

Update: as of >= Go 1.11, the Module system is now a standard part of the tooling and the GOPATH concept is close to becoming obsolete.

Run this from your server's command line:

 mysqlcheck --repair --all-databases

1. Prepare extra configuration file. Create a file named /etc/systemd/system/docker.service.d/docker.conf. Inside the file docker.conf, paste below content:

[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

Note that if there is no directory like docker.service.d or a file named docker.conf then you should create it.

2. Restart Docker. After saving this file, reload the configuration by systemctl daemon-reload and restart Docker by systemctl restart docker.service.

3. Check your Docker daemon. After restarting docker service, you can see the port in the output of systemctl status docker.service like /usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock.

Hope this may help

You don't need --header "Content-Length: $LENGTH".

curl --request POST --data-binary "@template_entry.xml" $URL

Note that GET request does not support content body widely.

Also remember that POST request have 2 different coding schema. This is first form:

You probably request this:

              multipart/form-data according to RFC2388. This
              enables uploading of binary files etc. To force the
              'content' part to be a file, prefix the file name
              with an @ sign. To just get the content part from a
              file, prefix the file name with the symbol <. The
              difference between @ and < is then that @ makes a
              file get attached in the post as a file upload,
              while the < makes a text field and just get the
              contents for that text field from a file.

If Xcode complains when linking, e.g. Library not found for -lPods, it doesn't detect the implicit dependencies.

Go to Product > Edit Scheme Click on Build Add the Pods static library, and make sure it's at the top of the list Clean and build again If that doesn't work, verify that the source for the spec you are trying to include has been pulled from github. Do this by looking in /Pods/. If it is empty (it should not be), verify that the ~/.cocoapods/master//.podspec has the correct git hub url in it. If still doesn't work, check your XCode build locations settings. Go to Preferences -> Locations -> Derived Data -> Advanced and set build location to “Relative to Workspace”.

Actually, there are four forms of this operator:

JavaFX (which comes bundled with Java 8) has the Pair< A,B > class

.gitkeep is just a placeholder. A dummy file, so Git will not forget about the directory, since Git tracks only files.

If you want an empty directory and make sure it stays 'clean' for Git, create a .gitignore containing the following lines within:

# .gitignore sample
###################

# Ignore all files in this dir...
*

# ... except for this one.
!.gitignore

If you desire to have only one type of files being visible to Git, here is an example how to filter everything out, except .gitignore and all .txt files:

# .gitignore to keep just .txt files
###################################

# Filter everything...
*

# ... except the .gitignore...
!.gitignore

# ... and all text files.
!*.txt

('#' indicates comments.)

A single quote is the start and end of a string. A semicolon is the end of a statement. So if they were doing a select like this:

Select *
From Students
Where (Name = '<NameGetsInsertedHere>')

The SQL would become:

Select *
From Students
Where (Name = 'Robert'); DROP TABLE STUDENTS; --')
--             ^-------------------------------^

On some systems, the select would get ran first followed by the drop statement! The message is: DONT EMBED VALUES INTO YOUR SQL. Instead use parameters!

Original Answer:

If you are ready to opt for CSS3, you can use css3 translate property. Resize based on whatever is bigger. If your height is bigger and width is smaller than container, width will be stretch to 100% and height will be trimmed from both side. Same goes for larger width as well.

Your need, HTML:

<div class="img-wrap">
  <img src="http://lorempixel.com/300/160/nature/" />
</div>
<div class="img-wrap">
  <img src="http://lorempixel.com/300/200/nature/" />
</div>
<div class="img-wrap">
  <img src="http://lorempixel.com/200/300/nature/" />
</div>

And CSS:

.img-wrap {
  width: 200px;
  height: 150px;
  position: relative;
  display: inline-block;
  overflow: hidden;
  margin: 0;
}

div > img {
  display: block;
  position: absolute;
  top: 50%;
  left: 50%;
  min-height: 100%;
  min-width: 100%;
  transform: translate(-50%, -50%);
}

Voila! Working: http://jsfiddle.net/shekhardesigner/aYrhG/

Explanation

DIV is set to the relative position. This means all the child elements will get the starting coordinates (origins) from where this DIV starts.

The image is set as a BLOCK element, min-width/height both set to 100% means to resize the image no matter of its size to be the minimum of 100% of it's parent. min is the key. If by min-height, the image height exceeded the parent's height, no problem. It will look for if min-width and try to set the minimum height to be 100% of parents. Both goes vice-versa. This ensures there are no gaps around the div but image is always bit bigger and gets trimmed by overflow:hidden;

Now image, this is set to an absolute position with left:50% and top:50%. Means push the image 50% from the top and left making sure the origin is taken from DIV. Left/Top units are measured from the parent.

Magic moment:

transform: translate(-50%, -50%);

Now, this translate function of CSS3 transform property moves/repositions an element in question. This property deals with the applied element hence the values (x, y) OR (-50%, -50%) means to move the image negative left by 50% of image size and move to the negative top by 50% of image size.

Eg. if Image size was 200px × 150px, transform:translate(-50%, -50%) will calculated to translate(-100px, -75px). % unit helps when we have various size of image.

This is just a tricky way to figure out centroid of the image and the parent DIV and match them.

Apologies for taking too long to explain!

I was successful using tidy command line utility. On linux I installed it quickly with apt-get install tidy. Then the command:

tidy -q -asxml --numeric-entities yes source.html >file.xml

gave an xml file, which I was able to process with xslt processor. However I needed to set up xhtml1 dtds correctly.

This is their homepage: html-tidy.org (and the legacy one: HTML Tidy)

Thanks to everyone's contributions to this question, I've come up with the following script. Change the values for $SvcName and $SvrName to suit your needs. This script will start the remote service if it is stopped, or stop it if it is started. And it uses the cool .WaitForStatus method to wait while the service responds.

#Change this values to suit your needs:
$SvcName = 'Spooler'
$SvrName = 'remotePC'

#Initialize variables:
[string]$WaitForIt = ""
[string]$Verb = ""
[string]$Result = "FAILED"
$svc = (get-service -computername $SvrName -name $SvcName)
Write-host "$SvcName on $SvrName is $($svc.status)"
Switch ($svc.status) {
    'Stopped' {
        Write-host "Starting $SvcName..."
        $Verb = "start"
        $WaitForIt = 'Running'
        $svc.Start()}
    'Running' {
        Write-host "Stopping $SvcName..."
        $Verb = "stop"
        $WaitForIt = 'Stopped'
        $svc.Stop()}
    Default {
        Write-host "$SvcName is $($svc.status).  Taking no action."}
}
if ($WaitForIt -ne "") {
    Try {  # For some reason, we cannot use -ErrorAction after the next statement:
        $svc.WaitForStatus($WaitForIt,'00:02:00')
    } Catch {
        Write-host "After waiting for 2 minutes, $SvcName failed to $Verb."
    }
    $svc = (get-service -computername $SvrName -name $SvcName)
    if ($svc.status -eq $WaitForIt) {$Result = 'SUCCESS'}
    Write-host "$Result`: $SvcName on $SvrName is $($svc.status)"
}

Of course, the account you run this under will need the proper privileges to access the remote computer and start and stop services. And when executing this against older remote machines, you might first have to install WinRM 3.0 on the older machine.

Does this mean that you want to add a class to the first button?

$('.o-links').click(function(e) {   // ... }).first().addClass('O_Nav_Current'); 

instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:

CSS:

.image-area {     width: 100%;     height: auto;     display: none; }  .image-area:first-of-type {     display: block; } 

JavaScript:

var $slides = $('.image-area'),     $btns = $('a.o-links');  $btns.on('click', function (e) {     var i = $btns.removeClass('O_Nav_Current').index(this);     $(this).addClass('O_Nav_Current');      $slides.filter(':visible').fadeOut(1000, function () {         $slides.eq(i).fadeIn(1000);     });      e.preventDefault();  }).first().addClass('O_Nav_Current');

I am combining the solutions from answers of @FredFoo and @Renaud. My solution is able to apply @Renaud's preprocessing on the text corpus of @FredFoo and then display pairwise similarities where the similarity is greater than 0. I ran this code on Windows by installing python and pip first. pip is installed as part of python but you may have to explicitly do it by re-running the installation package, choosing modify and then choosing pip. I use the command line to execute my python code saved in a file "similarity.py". I had to execute the following commands:

>set PYTHONPATH=%PYTHONPATH%;C:\_location_of_python_lib_
>python -m pip install sklearn
>python -m pip install nltk
>py similarity.py

The code for similarity.py is as follows:

from sklearn.feature_extraction.text import TfidfVectorizer
import nltk, string
import numpy as np
nltk.download('punkt') # if necessary...

stemmer = nltk.stem.porter.PorterStemmer()
remove_punctuation_map = dict((ord(char), None) for char in string.punctuation)

def stem_tokens(tokens):
    return [stemmer.stem(item) for item in tokens]

def normalize(text):
    return stem_tokens(nltk.word_tokenize(text.lower().translate(remove_punctuation_map)))

corpus = ["I'd like an apple", 
           "An apple a day keeps the doctor away", 
           "Never compare an apple to an orange", 
           "I prefer scikit-learn to Orange", 
           "The scikit-learn docs are Orange and Blue"]  

vect = TfidfVectorizer(tokenizer=normalize, stop_words='english')
tfidf = vect.fit_transform(corpus)   
                                                                                                                                                                                                                    
pairwise_similarity = tfidf * tfidf.T

#view the pairwise similarities 
print(pairwise_similarity)

print(normalize("The scikit-learn docs are Orange and Blue"))

I know this is not the OP's problem, but I ran into the same error with an entirely different basis, so I just wanted to drop it here in case anyone else has the same. This is Windows-specific, and I assume does not affect Linux users.

I had a LibreOffice doc file, call it final report.odt. I later changed its case to Final Report.odt. In Windows, this doesn't even count as a rename. final report.odt, Final Report.odt, FiNaL RePoRt.oDt are all the same. In Linux, these are all distinct.

When I eventually went to git rm "Final Report.odt" and got the "pathspec did not match any files" error. Only when I use the original casing at the time the file was added -- git rm "final report.odt" -- did it work.

Lesson learned: to change the case I should have instead done:

git mv "final report.odt" temp.odt
git mv temp.odt "Final Report.odt"

Again, that wasn't the problem for the OP here; and wouldn't affect a Linux user, as his posts shows he clearly is. I'm just including it for others who may have this problem in Windows git and stumble onto this question.
