I created my own jQuery plugin for this task, you can try it out here:

http://jsfiddle.net/Sk8erPeter/8NF4r/

You can create character counters on-the-fly (and also remaining character counters), you can define whether you want to chop text, you can define the suffix texts and you can also define a short format and its separator.

Here's an example usage:

$(document).ready(function () {

    $('#first_textfield').characterCounter();

    $('#second_textfield').characterCounter({
        maximumCharacters: 20,
        chopText: true
    });

    $('#third_textfield').characterCounter({
        maximumCharacters: 20,
        shortFormat: true,
        shortFormatSeparator: " / ",
        positionBefore: true,
        chopText: true
    });

    $('#fourth_textfield').characterCounter({
        maximumCharacters: 20,
        characterCounterNeeded: true,
        charactersRemainingNeeded: true,
        chopText: false
    });

    $('#first_textarea').characterCounter({
        maximumCharacters: 50,
        characterCounterNeeded: true,
        charactersRemainingNeeded: false,
        chopText: true
    });

    $('#second_textarea').characterCounter({
        maximumCharacters: 25
    });

});

Here's the code of the plugin:

/**
 * Character counter and limiter plugin for textfield and textarea form elements
 * @author Sk8erPeter
 */ 
(function ($) {
  $.fn.characterCounter = function (params) {
    // merge default and user parameters
    params = $.extend({
      // define maximum characters
      maximumCharacters: 1000,
      // create typed character counter DOM element on the fly
      characterCounterNeeded: true,
      // create remaining character counter DOM element on the fly
      charactersRemainingNeeded: true,
      // chop text to the maximum characters
      chopText: false,
      // place character counter before input or textarea element
      positionBefore: false,
      // class for limit excess
      limitExceededClass: "character-counter-limit-exceeded",
      // suffix text for typed characters
      charactersTypedSuffix: " characters typed",
      // suffix text for remaining characters
      charactersRemainingSuffixText: " characters left",
      // whether to use the short format (e.g. 123/1000)
      shortFormat: false,
      // separator for the short format
      shortFormatSeparator: "/"
    }, params);

    // traverse all nodes
    this.each(function () {
      var $this = $(this),
        $pluginElementsWrapper,
        $characterCounterSpan,
        $charactersRemainingSpan;

      // return if the given element is not a textfield or textarea
      if (!$this.is("input[type=text]") && !$this.is("textarea")) {
        return this;
      }

      // create main parent div
      if (params.characterCounterNeeded || params.charactersRemainingNeeded) {
        // create the character counter element wrapper
        $pluginElementsWrapper = $('<div>', {
          'class': 'character-counter-main-wrapper'
        });

        if (params.positionBefore) {
          $pluginElementsWrapper.insertBefore($this);
        } else {
          $pluginElementsWrapper.insertAfter($this);
        }
      }

      if (params.characterCounterNeeded) {
        $characterCounterSpan = $('<span>', {
          'class': 'counter character-counter',
          'text': 0
        });

        if (params.shortFormat) {
          $characterCounterSpan.appendTo($pluginElementsWrapper);

          var $shortFormatSeparatorSpan = $('<span>', {
            'html': params.shortFormatSeparator
          }).appendTo($pluginElementsWrapper);

        } else {
          // create the character counter element wrapper
          var $characterCounterWrapper = $('<div>', {
            'class': 'character-counter-wrapper',
            'html': params.charactersTypedSuffix
          });

          $characterCounterWrapper.prepend($characterCounterSpan);
          $characterCounterWrapper.appendTo($pluginElementsWrapper);
        }
      }

      if (params.charactersRemainingNeeded) {

        $charactersRemainingSpan = $('<span>', {
          'class': 'counter characters-remaining',
          'text': params.maximumCharacters
        });

        if (params.shortFormat) {
          $charactersRemainingSpan.appendTo($pluginElementsWrapper);
        } else {
          // create the character counter element wrapper
          var $charactersRemainingWrapper = $('<div>', {
            'class': 'characters-remaining-wrapper',
            'html': params.charactersRemainingSuffixText
          });
          $charactersRemainingWrapper.prepend($charactersRemainingSpan);
          $charactersRemainingWrapper.appendTo($pluginElementsWrapper);
        }
      }

      $this.keyup(function () {

        var typedText = $this.val();
        var textLength = typedText.length;
        var charactersRemaining = params.maximumCharacters - textLength;

        // chop the text to the desired length
        if (charactersRemaining < 0 && params.chopText) {
          $this.val(typedText.substr(0, params.maximumCharacters));
          charactersRemaining = 0;
          textLength = params.maximumCharacters;
        }

        if (params.characterCounterNeeded) {
          $characterCounterSpan.text(textLength);
        }

        if (params.charactersRemainingNeeded) {
          $charactersRemainingSpan.text(charactersRemaining);

          if (charactersRemaining <= 0) {
            if (!$charactersRemainingSpan.hasClass(params.limitExceededClass)) {
              $charactersRemainingSpan.addClass(params.limitExceededClass);
            }
          } else {
            $charactersRemainingSpan.removeClass(params.limitExceededClass);
          }
        }
      });

    });

    // allow jQuery chaining
    return this;

  };
})(jQuery);

Note also that "key" does not necessarily mean primary key. Something like this will work:

CREATE TABLE book (
    isbn             BIGINT NOT NULL PRIMARY KEY,
    id               INT    NOT NULL AUTO_INCREMENT,
    accepted_terms   BIT(1) NOT NULL,
    accepted_privacy BIT(1) NOT NULL,
    INDEX(id)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

This is a contrived example and probably not the best idea, but it can be very useful in certain cases.

This is a pretty clean way to do it:

myStr = ("firstPartOfMyString"+
         "secondPartOfMyString"+
         "thirdPartOfMyString")

I have created simple demo class for your better reference.

FirstActivity.java

 public class FirstActivity extends AppCompatActivity {

    private static final String TAG = FirstActivity.class.getSimpleName();
    private static final int REQUEST_CODE = 101;
    private Button btnMoveToNextScreen;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnMoveToNextScreen = (Button) findViewById(R.id.btnMoveToNext);
        btnMoveToNextScreen.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent mIntent = new Intent(FirstActivity.this, SecondActivity.class);
                startActivityForResult(mIntent, REQUEST_CODE);
            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if(resultCode == RESULT_OK){
            if(requestCode == REQUEST_CODE && data !=null) {
                String strMessage = data.getStringExtra("keyName");
                Log.i(TAG, "onActivityResult: message >>" + strMessage);
            }
        }

    }
}

And here is SecondActivity.java

public class SecondActivity extends AppCompatActivity {

    private static final String TAG = SecondActivity.class.getSimpleName();
    private Button btnMoveToPrevious;
    private EditText editText;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);

        editText = (EditText) findViewById(R.id.editText);

        btnMoveToPrevious = (Button) findViewById(R.id.btnMoveToPrevious);
        btnMoveToPrevious.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                String message = editText.getEditableText().toString();

                Intent mIntent = new Intent();
                mIntent.putExtra("keyName", message);
                setResult(RESULT_OK, mIntent);
                finish();

            }
        });

    }
}

I had to do this to get the result that I wanted:

<td style="font-size:3px; float:left; height:5px; vertical-align:middle;" colspan="7"><div style="font-size:3px; height:5px; vertical-align:middle;"><b><hr></b></div></td>

It refused to work with only the cell or the div and needed both.

There are no perfect answers provided here except Asaf's answer which doesn't provide any code nor any example, so I would like to contribute mine...

Inorder to make vertical-align: middle; work, you need to use display: table; for your ul element and display: table-cell; for li elements and than you can use vertical-align: middle; for li elements.

You don't need to provide any explicit margins, paddings to make your text vertically middle.

Demo

ul.catBlock{
    display: table;
    width:960px; 
    height: 270px; 
    border:1px solid #ccc; 
}

ul.catBlock li {
    list-style: none;
    display: table-cell; 
    text-align: center; 
    width:160px; 
    vertical-align: middle;
}

ul.catBlock li a { 
    display: block;
}

The window.open() function will also allow this if you have a reference to the window created, provided it is on the same domain. If the variable is used server side you should be using a $_SESSION variable (assuming you are using PHP).

Here's what I would use:

 (?<!\S)stackoverflow(?!\S)

In other words, match "stackoverflow" if it's not preceded by a non-whitespace character and not followed by a non-whitespace character.

This is neater (IMO) than the "space-or-anchor" approach, and it doesn't assume the string starts and ends with word characters like the \b approach does.

A more efficient version of this answer:

 /**
 * Is element within visible region of a scrollable container
 * @param {HTMLElement} el - element to test
 * @returns {boolean} true if within visible region, otherwise false
 */
 function isScrolledIntoView(el) {
      var rect = el.getBoundingClientRect();
      return (rect.top >= 0) && (rect.bottom <= window.innerHeight);
 }

From spark 3.0

data_cl = reg_data.exceptAll(data_fr)

Another native JS solution that can be useful for "complex" or deeply nested elements is to use NodeIterator. Put NodeFilter.SHOW_TEXT as the second argument ("whatToShow"), and iterate over just the text node children of the element.

var root = document.querySelector('p'),_x000D_
    iter = document.createNodeIterator(root, NodeFilter.SHOW_TEXT),_x000D_
    textnode;_x000D_
_x000D_
// print all text nodes_x000D_
while (textnode = iter.nextNode()) {_x000D_
  console.log(textnode.textContent)_x000D_
}

<p>_x000D_
<br>some text<br>123_x000D_
</p>

You can also use TreeWalker. The difference between the two is that NodeIterator is a simple linear iterator, while TreeWalker allows you to navigate via siblings and ancestors as well.

The .browser call has been removed in jquery 1.9 have a look at http://jquery.com/upgrade-guide/1.9/ for more details.

You could also get all relevant details from performance_schema:

SELECT
OBJECT_SCHEMA
,OBJECT_NAME
,GROUP_CONCAT(DISTINCT EXTERNAL_LOCK)
FROM performance_schema.table_handles 
WHERE EXTERNAL_LOCK IS NOT NULL

GROUP BY
OBJECT_SCHEMA
,OBJECT_NAME

This works similar as

show open tables WHERE In_use > 0

Try something like this inside ThisOutlookSession:

Private Sub Application_NewMail()
    Call Your_main_macro
End Sub

My outlook vba just fired when I received an email and had that application event open.

Edit: I just tested a hello world msg box and it ran after being called in the application_newmail event when an email was received.

You can Use This code.

var checkbox = document.getElementById("dlCheckAll4Delete");
checkbox.addEventListener("click", function (event) {
  let checkboxes = document.querySelectorAll(".dlMultiDelete");
  checkboxes.forEach(function (ele) {
    ele.checked = !!checkbox.checked;
  });
});

I dont know why , but "pip install mechanize" didnt work for me . easy install worked anyway . Try this :

sudo easy_install mechanize

Your code is working fine using bootatrap v3.3.7, but you can use word-break: break-word if it's not working at your end.

which would then look like this -

I follow the Python Idioms and Efficiency guidelines, by Rob Knight. I think they are exactly the same as PEP 8, but are more synthetic and based on examples.

If you are using wxPython you might also want to check Style Guide for wxPython code, by Chris Barker, as well.

I am getting a very simple solution to set ActionBar Title in either fragment or any activity without any headache.

Just modify the xml where is defined Toolbar as below :

<android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@color/colorPrimaryDark"
            app:popupTheme="@style/AppTheme.PopupOverlay" >

            <TextView
                style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
                android:id="@+id/toolbar_title"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="@string/app_name"
                />
            </android.support.v7.widget.Toolbar>

    </android.support.design.widget.AppBarLayout> 

1) If you want to set the actionbar in a fragment then :

Toolbar toolbar = findViewById(R.id.toolbar);
TextView toolbarTitle = (TextView) toolbar.findViewById(R.id.toolbar_title);

For using it from anywhere, you can define a method in the activity

public void setActionBarTitle(String title) {
        toolbarTitle.setText(title);
    }

To call this method in activity, simply call it.

setActionBarTitle("Your Title")

To call this method from fragment of the activity, simply call it.

((MyActivity)getActivity()).setActionBarTitle("Your Title");

Below a fully functional method to get hard disk serial number:

public string GetHardDiskSerialNo()
    {
        ManagementClass mangnmt = new ManagementClass("Win32_LogicalDisk");
        ManagementObjectCollection mcol = mangnmt.GetInstances();
        string result = "";
        foreach (ManagementObject strt in mcol)
        {
            result += Convert.ToString(strt["VolumeSerialNumber"]);
        }
        return result;
    }

Its tested in all version of IE, Chrome, FF & Safari

// JavaScript code

    <script type="text/javascript">
    <!-- begin hiding
    function expandSELECT(sel) {
      sel.style.width = '';
    }
    function contractSELECT(sel) {
      sel.style.width = '100px';
    }
    // end hiding -->
    </script>

// Html code

    <select name="sideeffect" id="sideeffect"  style="width:100px;" onfocus="expandSELECT(this);" onblur="contractSELECT(this);" >
      <option value="0" selected="selected" readonly="readonly">Select</option>
    <option value="1" >Apple</option>
    <option value="2" >Orange + Banana + Grapes</option>

They need to all have the same name.

Here's an option if you need to escape multiple %'s in a string with some already escaped.

(?:[^%]|^)(?:(%%)+|)(%)(?:[^%])

To sanitise the message before passing it to String.format, you can use the following

Pattern p = Pattern.compile("(?:[^%]|^)(?:(%%)+|)(%)(?:[^%])");
Matcher m1 = p.matcher(log);

StringBuffer buf = new StringBuffer();
while (m1.find())
    m1.appendReplacement(buf, log.substring(m1.start(), m1.start(2)) + "%%" + log.substring(m1.end(2), m1.end()));

// Return the sanitised message
String escapedString = m1.appendTail(buf).toString();

This works with any number of formatting characters, so it will replace % with %%, %%% with %%%%, %%%%% with %%%%%% etc.

It will leave any already escaped characters alone (e.g. %%, %%%% etc.)

Either you can use CSV functions or PHPExcel

or you can try like below

<?php
$file="demo.xls";
$test="<table  ><tr><td>Cell 1</td><td>Cell 2</td></tr></table>";
header("Content-type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=$file");
echo $test;
?>

The header for .xlsx files is Content-type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

Let excel do the work.

Declaration says "this thing exists somewhere":

int foo();       // function
extern int bar;  // variable
struct T
{
   static int baz;  // static member variable
};

Definition says "this thing exists here; make memory for it":

int foo() {}     // function
int bar;         // variable
int T::baz;      // static member variable

Initialisation is optional at the point of definition for objects, and says "here is the initial value for this thing":

int bar = 0;     // variable
int T::baz = 42; // static member variable

Sometimes it's possible at the point of declaration instead:

struct T
{
   static int baz = 42;
};

…but that's getting into more complex features.

https://golang.org/ref/spec#For_range

A "for" statement with a "range" clause iterates through all entries of an array, slice, string or map, or values received on a channel. For each entry it assigns iteration values to corresponding iteration variables and then executes the block.

As an example:

for index, element := range someSlice {
    // index is the index where we are
    // element is the element from someSlice for where we are
}

If you don't care about the index, you can use _:

for _, element := range someSlice {
    // element is the element from someSlice for where we are
}

The underscore, _, is the blank identifier, an anonymous placeholder.

Works GReat.

<input type="text" name="cat_q" id="cat_q">  

$(document).ready(function(){
    $("#btn_cat div a").click(function(){
       alert($(this).text());

    });
});

I ran into this issue when using IntelliJ 14's bundled Maven 3 instance.

I switched to using my own local Maven instance, via:

Settings -> Build, Execution, Deployment -> Build Tools -> Maven -> Maven Home Directory

Then added the path to my locally installed instance.

This got the dependencies to magically appear.

Perhaps the two most efficient ways to find the last index:

def rindex(lst, value):
    lst.reverse()
    i = lst.index(value)
    lst.reverse()
    return len(lst) - i - 1

def rindex(lst, value):
    return len(lst) - operator.indexOf(reversed(lst), value) - 1

Both take only O(1) extra space and the two in-place reversals of the first solution are much faster than creating a reverse copy. Let's compare it with the other solutions posted previously:

def rindex(lst, value):
    return len(lst) - lst[::-1].index(value) - 1

def rindex(lst, value):
    return len(lst) - next(i for i, val in enumerate(reversed(lst)) if val == value) - 1

Benchmark results, my solutions are the red and green ones:

This is for searching a number in a list of a million numbers. The x-axis is for the location of the searched element: 0% means it's at the start of the list, 100% means it's at the end of the list. All solutions are fastest at location 100%, with the two reversed solutions taking pretty much no time for that, the double-reverse solution taking a little time, and the reverse-copy taking a lot of time.

A closer look at the right end:

At location 100%, the reverse-copy solution and the double-reverse solution spend all their time on the reversals (index() is instant), so we see that the two in-place reversals are about seven times as fast as creating the reverse copy.

The above was with lst = list(range(1_000_000, 2_000_001)), which pretty much creates the int objects sequentially in memory, which is extremely cache-friendly. Let's do it again after shuffling the list with random.shuffle(lst) (probably less realistic, but interesting):

All got a lot slower, as expected. The reverse-copy solution suffers the most, at 100% it now takes about 32 times (!) as long as the double-reverse solution. And the enumerate-solution is now second-fastest only after location 98%.

Overall I like the operator.indexOf solution best, as it's the fastest one for the last half or quarter of all locations, which are perhaps the more interesting locations if you're actually doing rindex for something. And it's only a bit slower than the double-reverse solution in earlier locations.

All benchmarks done with CPython 3.9.0 64-bit on Windows 10 Pro 1903 64-bit.

I use metaclasses and decorators for generate tests. You can check my implementation python_wrap_cases. This library doesn't require any test frameworks.

Your example:

import unittest
from python_wrap_cases import wrap_case


@wrap_case
class TestSequence(unittest.TestCase):

    @wrap_case("foo", "a", "a")
    @wrap_case("bar", "a", "b")
    @wrap_case("lee", "b", "b")
    def testsample(self, name, a, b):
        print "test", name
        self.assertEqual(a, b)

Console output:

testsample_u'bar'_u'a'_u'b' (tests.example.test_stackoverflow.TestSequence) ... test bar
FAIL
testsample_u'foo'_u'a'_u'a' (tests.example.test_stackoverflow.TestSequence) ... test foo
ok
testsample_u'lee'_u'b'_u'b' (tests.example.test_stackoverflow.TestSequence) ... test lee
ok

Also you may use generators. For example this code generate all possible combinations of tests with arguments a__list and b__list

import unittest
from python_wrap_cases import wrap_case


@wrap_case
class TestSequence(unittest.TestCase):

    @wrap_case(a__list=["a", "b"], b__list=["a", "b"])
    def testsample(self, a, b):
        self.assertEqual(a, b)

Console output:

testsample_a(u'a')_b(u'a') (tests.example.test_stackoverflow.TestSequence) ... ok
testsample_a(u'a')_b(u'b') (tests.example.test_stackoverflow.TestSequence) ... FAIL
testsample_a(u'b')_b(u'a') (tests.example.test_stackoverflow.TestSequence) ... FAIL
testsample_a(u'b')_b(u'b') (tests.example.test_stackoverflow.TestSequence) ... ok

git checkout master

That's result something like this:

Warning: you are leaving 2 commits behind, not connected to
any of your branches:

1e7822f readme
0116b5b returned to clean django

If you want to keep them by creating a new branch, this may be a good time to do so with:
git branch new_branch_name 1e7822f25e376d6a1182bb86a0adf3a774920e1e

So, let's do it:

git merge 1e7822f25e376d6a1182bb86a0adf3a774920e1e

It should be mentioned that the Accept header tells the server something about what we are accepting back, whereas the relevant header in this context is Content-Type

It's often advisable to specify Content-Type as application/json when sending JSON. For curl the syntax is:

-H 'Content-Type: application/json'

So the complete curl command will be:

curl -H 'Content-Type: application/json' -H 'Accept: application/json' -X PUT -d '{"tags":["tag1","tag2"],"question":"Which band?","answers":[{"id":"a0","answer":"Answer1"},{"id":"a1","answer":"answer2"}]}' http://example.com/service`

const isEmpty = val => val == null || !(Object.keys(val) || val).length;

You can try this too, If you don't want to do this by your method.

    Arrays.sort(arr);
    System.out.println("Min value "+arr[0]);
    System.out.println("Max value "+arr[arr.length-1]);

Try closing and reopening the file, then press Ctrl+F11.

Verify that the name of the file you are running is the same as the name of the project you are working in, and that the name of the public class in that file is the same as the name of the project you are working in as well.

Otherwise, restart Eclipse. Let me know if this solves the problem! Otherwise, comment, and I'll try and help.

instanceof can be used to determine the actual type of an object:

class A { }  
class C extends A { } 
class D extends A { } 

public static void testInstance(){
    A c = new C();
    A d = new D();
    Assert.assertTrue(c instanceof A && d instanceof A);
    Assert.assertTrue(c instanceof C && d instanceof D);
    Assert.assertFalse(c instanceof D);
    Assert.assertFalse(d instanceof C);
}

Here is a function I use:

var map =  new google.maps.Map(document.getElementById('map'), {
            center: new google.maps.LatLng(52.2, 5),
            mapTypeId: google.maps.MapTypeId.ROADMAP,
            zoom: 7
        });

function zoomTo(level) {
        google.maps.event.addListener(map, 'zoom_changed', function () {
            zoomChangeBoundsListener = google.maps.event.addListener(map, 'bounds_changed', function (event) {
                if (this.getZoom() > level && this.initialZoom == true) {
                    this.setZoom(level);
                    this.initialZoom = false;
                }
                google.maps.event.removeListener(zoomChangeBoundsListener);
            });
        });
    }

It seems the interface has changed in .NET 4.0. There is the following method that achieves all of the above. As Tommy Engebretsen suggested, putting it in a TextChanged event handler makes it automatic.

Copying my own answer from How do I run a Node.js application as its own process?

2015 answer: nearly every Linux distro comes with systemd, which means forever, monit, PM2, etc are no longer necessary - your OS already handles these tasks.

Make a myapp.service file (replacing 'myapp' with your app's name, obviously):

[Unit]
Description=My app

[Service]
ExecStart=/var/www/myapp/app.js
Restart=always
User=nobody
# Note Debian/Ubuntu uses 'nogroup', RHEL/Fedora uses 'nobody'
Group=nogroup
Environment=PATH=/usr/bin:/usr/local/bin
Environment=NODE_ENV=production
WorkingDirectory=/var/www/myapp

[Install]
WantedBy=multi-user.target

Note if you're new to Unix: /var/www/myapp/app.js should have #!/usr/bin/env node on the very first line and have the executable mode turned on chmod +x myapp.js.

Copy your service file into the /etc/systemd/system.

Start it with systemctl start myapp.

Enable it to run on boot with systemctl enable myapp.

See logs with journalctl -u myapp

This is taken from How we deploy node apps on Linux, 2018 edition, which also includes commands to generate an AWS/DigitalOcean/Azure CloudConfig to build Linux/node servers (including the .service file).

This works for me (reference):

# PHP error handling for production servers

IMO, implementation #1 is typical and being short and idiomatic for Perl trumps the others for that alone. A benchmark of the three choices might offer you insight into speed, at least.

Gradle Build Tools 2.2.0+ - The closest the NDK has ever come to being called 'magic'

In trying to avoid experimental and frankly fed up with the NDK and all its hackery I am happy that 2.2.x of the Gradle Build Tools came out and now it just works. The key is the externalNativeBuild and pointing ndkBuild path argument at an Android.mk or change ndkBuild to cmake and point the path argument at a CMakeLists.txt build script.

android {
    compileSdkVersion 19
    buildToolsVersion "25.0.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 19

        ndk {
            abiFilters 'armeabi', 'armeabi-v7a', 'x86'
        }

        externalNativeBuild {
            cmake {
                cppFlags '-std=c++11'
                arguments '-DANDROID_TOOLCHAIN=clang',
                        '-DANDROID_PLATFORM=android-19',
                        '-DANDROID_STL=gnustl_static',
                        '-DANDROID_ARM_NEON=TRUE',
                        '-DANDROID_CPP_FEATURES=exceptions rtti'
            }
        }
    }

    externalNativeBuild {
        cmake {
             path 'src/main/jni/CMakeLists.txt'
        }
        //ndkBuild {
        //   path 'src/main/jni/Android.mk'
        //}
    }
}

For much more detail check Google's page on adding native code.

After this is setup correctly you can ./gradlew installDebug and off you go. You will also need to be aware that the NDK is moving to clang since gcc is now deprecated in the Android NDK.

Android Studio Clean and Build Integration - DEPRECATED

The other answers do point out the correct way to prevent the automatic creation of Android.mk files, but they fail to go the extra step of integrating better with Android Studio. I have added the ability to actually clean and build from source without needing to go to the command-line. Your local.properties file will need to have ndk.dir=/path/to/ndk

apply plugin: 'com.android.application'

android {
    compileSdkVersion 14
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.application"
        minSdkVersion 14
        targetSdkVersion 14

        ndk {
            moduleName "YourModuleName"
        }
    }

    sourceSets.main {
        jni.srcDirs = [] // This prevents the auto generation of Android.mk
        jniLibs.srcDir 'src/main/libs' // This is not necessary unless you have precompiled libraries in your project.
    }

    task buildNative(type: Exec, description: 'Compile JNI source via NDK') {
        def ndkDir = android.ndkDirectory
        commandLine "$ndkDir/ndk-build",
                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source
                '-j', Runtime.runtime.availableProcessors(),
                'all',
                'NDK_DEBUG=1'
    }

    task cleanNative(type: Exec, description: 'Clean JNI object files') {
        def ndkDir = android.ndkDirectory
        commandLine "$ndkDir/ndk-build",
                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source
                'clean'
    }

    clean.dependsOn 'cleanNative'

    tasks.withType(JavaCompile) {
        compileTask -> compileTask.dependsOn buildNative
    }
}

dependencies {
    compile 'com.android.support:support-v4:20.0.0'
}

The src/main/jni directory assumes a standard layout of the project. It should be the relative from this build.gradle file location to the jni directory.

Gradle - for those having issues

Also check this Stack Overflow answer.

It is really important that your gradle version and general setup are correct. If you have an older project I highly recommend creating a new one with the latest Android Studio and see what Google considers the standard project. Also, use gradlew. This protects the developer from a gradle version mismatch. Finally, the gradle plugin must be configured correctly.

And you ask what is the latest version of the gradle plugin? Check the tools page and edit the version accordingly.

Final product - /build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

// Running 'gradle wrapper' will generate gradlew - Getting gradle wrapper working and using it will save you a lot of pain.
task wrapper(type: Wrapper) {
    gradleVersion = '2.2'
}

// Look Google doesn't use Maven Central, they use jcenter now.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Make sure gradle wrapper generates the gradlew file and gradle/wrapper subdirectory. This is a big gotcha.

ndkDirectory

This has come up a number of times, but android.ndkDirectory is the correct way to get the folder after 1.1. Migrating Gradle Projects to version 1.0.0. If you're using an experimental or ancient version of the plugin your mileage may vary.

In new version of material 2 which its control name starts with mat prefix setErrors() doesn't work, instead Juila's answer can be changed to:

formData.form.controls['email'].markAsTouched();

Nowadays you don't even need jQuery:) fetch API support table

let result = fetch('url', {method: 'POST', body: new FormData(document.querySelector("#form"))})

just do it easy with click action

in your main component html make reference #scrollContainer

<div class="main-container" #scrollContainer>
    <router-outlet (activate)="onActivate($event, scrollContainer)"></router-outlet>
</div>

in main component .ts

onActivate(e, scrollContainer) {
    scrollContainer.scrollTop = 0;
}

Try setting the system default encoding as utf-8 at the start of the script, so that all strings are encoded using that.

Example -

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

The above should set the default encoding as utf-8 .

Your main() method is static, but it is referencing two non-static members: con2 and getConnectionUrl2(). You need to do one of three things:

1) Make con2 and getConnectionUrl2() static.

2) Inside main(), create an instance of class testconnect and access con2 and getConnectionUrl2() off of that.

3) Break out a different class to hold con2 and getConnectionUrl2() so that testconnect only has main in it. It will still need to instantiate the different class and call the methods off that.

Option #3 is the best option. #1 is the worst.

But, you cannot access non-static members from within a static method.

Using itertools.count:

import itertools
for i in itertools.count(start=1):
    if there_is_a_reason_to_break(i):
        break

In Python 2, range() and xrange() were limited to sys.maxsize. In Python 3 range() can go much higher, though not to infinity:

import sys
for i in range(sys.maxsize**10):  # you could go even higher if you really want
    if there_is_a_reason_to_break(i):
        break

So it's probably best to use count().

Just an update, its seem that PHP guys are working on supporting thread and its available now.

Here is the link to it: http://php.net/manual/en/book.pthreads.php

From http://www.dba-oracle.com/t_isnumeric.htm

LENGTH(TRIM(TRANSLATE(, ' +-.0123456789', ' '))) is null

If there is anything left in the string after the TRIM it must be non-numeric characters.

Please try this. This query can be used for date comparison

select * from [User] U where convert(varchar(10),U.DateCreated, 120) = '2014-02-07'

This can also be achieved using the Scalar-Valued Function in MSSQL 2008
Declare your function as following,

CREATE FUNCTION [dbo].[FunctionName]
(@MaskId INT)
RETURNS Varchar(500) 
AS
BEGIN

    DECLARE @SchoolName varchar(500)                        

    SELECT @SchoolName =ISNULL(@SchoolName ,'')+ MD.maskdetail +', ' 
    FROM maskdetails MD WITH (NOLOCK)       
    AND MD.MaskId=@MaskId

    RETURN @SchoolName

END

And then your final query will be like

SELECT m.maskid,m.maskname,m.schoolid,s.schoolname,
(SELECT [dbo].[FunctionName](m.maskid)) 'maskdetail'
FROM tblmask m JOIN school s on s.id = m.schoolid 
ORDER BY m.maskname ;

Note: You may have to change the function, as I don't know the complete table structure.

Another solutions are assign RangeIndex or range:

df.index = pd.RangeIndex(len(df.index))

df.index = range(len(df.index))

It is faster:

df = pd.DataFrame({'a':[8,7], 'c':[2,4]}, index=[7,8])
df = pd.concat([df]*10000)
print (df.head())

In [298]: %timeit df1 = df.reset_index(drop=True)
The slowest run took 7.26 times longer than the fastest. This could mean that an intermediate result is being cached.
10000 loops, best of 3: 105 µs per loop

In [299]: %timeit df.index = pd.RangeIndex(len(df.index))
The slowest run took 15.05 times longer than the fastest. This could mean that an intermediate result is being cached.
100000 loops, best of 3: 7.84 µs per loop

In [300]: %timeit df.index = range(len(df.index))
The slowest run took 7.10 times longer than the fastest. This could mean that an intermediate result is being cached.
100000 loops, best of 3: 14.2 µs per loop

NumPy's main object is the homogeneous multidimensional array. In Numpy dimensions are called axes. The number of axes is rank. Numpy's array class is called ndarray. It is also known by the alias array. The more important attributes of an ndarray object are:

ndarray.ndim
the number of axes (dimensions) of the array. In the Python world, the number of dimensions is referred to as rank.

ndarray.shape
the dimensions of the array. This is a tuple of integers indicating the size of the array in each dimension. For a matrix with n rows and m columns, shape will be (n,m). The length of the shape tuple is therefore the rank, or number of dimensions, ndim.

ndarray.size
the total number of elements of the array. This is equal to the product of the elements of shape.

I hope my encoding here is right ;D To make it faster just use the ugly getInstance() call of GregorianCalendar instead of constructor call:

import java.util.GregorianCalendar;
import javax.xml.datatype.DatatypeFactory;
import javax.xml.datatype.XMLGregorianCalendar;

public class DateTest {

   public static void main(final String[] args) throws Exception {
      // do not forget the type cast :/
      GregorianCalendar gcal = (GregorianCalendar) GregorianCalendar.getInstance();
      XMLGregorianCalendar xgcal = DatatypeFactory.newInstance()
            .newXMLGregorianCalendar(gcal);
      System.out.println(xgcal);
   }

}

from pyspark.sql.functions import udf
from pyspark.sql.types import *
func_name = udf(
    lambda val: val, # do sth to val
    StringType()
)
df.withColumn('new_col', func_name(df.old_col))

You can declare globals by augmenting the window interface:

import jQuery from '@types/jquery';

declare global {
    interface Window {
        jQuery: typeof jQuery;
        $: typeof jQuery;
    }
}

do {
    // get the documents folder url
    if let documentDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first {
        // create the destination url for the text file to be saved
        let fileURL = documentDirectory.appendingPathComponent("file.txt")

        let text = "Hello World !!!"
        // writing to disk

Use a for loop to iterate through your array. For each string, create a new option element, assign the string as its innerHTML and value, and then append it to the select element.

var cuisines = ["Chinese","Indian"];     
var sel = document.getElementById('CuisineList');
for(var i = 0; i < cuisines.length; i++) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisines[i];
    opt.value = cuisines[i];
    sel.appendChild(opt);
}

DEMO

UPDATE: Using createDocumentFragment and forEach

If you have a very large list of elements that you want to append to a document, it can be non-performant to append each new element individually. The DocumentFragment acts as a light weight document object that can be used to collect elements. Once all your elements are ready, you can execute a single appendChild operation so that the DOM only updates once, instead of n times.

var cuisines = ["Chinese","Indian"];     

var sel = document.getElementById('CuisineList');
var fragment = document.createDocumentFragment();

cuisines.forEach(function(cuisine, index) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisine;
    opt.value = cuisine;
    fragment.appendChild(opt);
});

sel.appendChild(fragment);

DEMO

This is my favoured approach:

git branch new_branch_name $(echo "commit message" | git commit-tree HEAD^{tree})

This will create a new branch with one commit that adds everything in HEAD. It doesn't alter anything else, so it's completely safe.

Log from Silverlight

When using NLog with Silverlight you can send the trace to the server side via the provided web service. You can also write to a local file in the Isolated Storage, which come in handy if the web server is unavailable. See here for details, i.e. use something like this to make yourself a target:

namespace NLogTargets
{
    [Target("IsolatedStorageTarget")]
    public sealed class IsolatedStorageTarget : TargetWithLayout
    {
        IsolatedStorageFile _storageFile = null;
        string _fileName = "Nlog.log"; // Default. Configurable through the 'filename' attribute in nlog.config

        public IsolatedStorageTarget()
        {
        }

        ~IsolatedStorageTarget()
        {
            if (_storageFile != null)
            {
                _storageFile.Dispose();
                _storageFile = null;
            }
        }

        public string filename
        {
            set
            {
                _fileName = value; 
            }
            get
            {
                return _fileName;  
            }
         }

        protected override void Write(LogEventInfo logEvent)
        {
            try
            {
                writeToIsolatedStorage(this.Layout.Render(logEvent));
            }
            catch (Exception e)
            {
                // Not much to do about his....
            }
        }

        public void writeToIsolatedStorage(string msg)
        {
            if (_storageFile == null)
                _storageFile = IsolatedStorageFile.GetUserStoreForApplication();
            using (IsolatedStorageFile isolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
            {
                // The isolated storage is limited in size. So, when approaching the limit
                // simply purge the log file. (Yeah yeah, the file should be circular, I know...)
                if (_storageFile.AvailableFreeSpace < msg.Length * 100)
                {
                    using (IsolatedStorageFileStream stream = new IsolatedStorageFileStream(_fileName, FileMode.Truncate, FileAccess.Write, isolatedStorage))
                    { }
                }
                // Write to isolated storage
                using (IsolatedStorageFileStream stream = new IsolatedStorageFileStream(_fileName, FileMode.Append, FileAccess.Write, isolatedStorage))
                {
                    using (TextWriter writer = new StreamWriter(stream))
                    {
                        writer.WriteLine(msg);
                    }
                }
            }
        }
    } 
}

I posted this answer too over on superuser.

To do this you will need to set up a custom event filter in Task Scheduler.

Triggers > New > Custom > Edit Event > XML

and paste the following:

<QueryList>
  <Query Id="0" Path="System">
    <Select Path="System">
    *[System[Provider[@Name='User32'] and (Level=4 or Level=0) and (EventID=1074)]]
   and 
     *[EventData[Data[@Name='param5'] and (Data='power off')]]
    </Select>
  </Query>
</QueryList>

This will filter out the power off event only.

If you look in the event viewer you can see under Windows Logs > System under Details tab>XML View that there's this.

- <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
- <System>
  <Provider Name="User32" Guid="{xxxxx-xxxxxxxxxxx-xxxxxxxxxxxxxx-x-x}" EventSourceName="User32" /> 
  <EventID Qualifiers="32768">1074</EventID> 
  <Version>0</Version> 
  <Level>4</Level> 
  <Task>0</Task> 
  <Opcode>0</Opcode> 
  <Keywords>0x8080000000000000</Keywords> 
  <TimeCreated SystemTime="2021-01-19T18:23:32.6133523Z" /> 
  <EventRecordID>26696</EventRecordID> 
  <Correlation /> 
  <Execution ProcessID="1056" ThreadID="11288" /> 
  <Channel>System</Channel> 
  <Computer>DESKTOP-REDACTED</Computer> 
  <Security UserID="x-x-x-xx-xxxxxxxxxx-xxxxxxxxxx-xxxxxxxxxx-xxxx" /> 
  </System>
- <EventData>
  <Data Name="param1">Explorer.EXE</Data> 
  <Data Name="param2">DESKTOP-REDACTED</Data> 
  <Data Name="param3">Other (Unplanned)</Data> 
  <Data Name="param4">0x0</Data> 
  <Data Name="param5">power off</Data> 
  <Data Name="param6" /> 
  <Data Name="param7">DESKTOP-REDACTED\username</Data> 
  </EventData>
  </Event>

You can test the query with the query list code above in the event viewer by clicking

Create Custom View... > XML > Edit query manually

and pasting the code, giving it a name Power Off Events Only before you try it in the Task Scheduler.

enter code hereif you are using linux you have to edit the

`/etc/apache2/sites-available/000-default.conf`

under the Documentroot . add the following code

`<Directory /var/www/>
  AllowOverride all
  Require all granted
</Directory>` 

then ,

`sudo service apache2 restart`

and you have to enable the apache mod rewrite

`sudo a2enmod rewrite`

You did not add # before id of the button. You do not have right selector in your jquery code. So jquery is never execute in your button click. its submitted your form directly not passing any ajax request.

See documentation: http://api.jquery.com/category/selectors/
its your friend.

Try this:

It seems that id: $("#Shareitem").val() is wrong if you want to pass the value of

<input type="hidden" name="id" value="" id="id">

you need to change this line:

id: $("#Shareitem").val()

by

id: $("#id").val()

All together:

 <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
    <script>
    $(document).ready(function(){
      $("#Shareitem").click(function(e){
          e.preventDefault();
        $.ajax({type: "POST",
                url: "/imball-reagens/public/shareitem",
                data: { id: $("#Shareitem").val(), access_token: $("#access_token").val() },
                success:function(result){
          $("#sharelink").html(result);
        }});
      });
    });
    </script>

The Json conversion should work out-of-the box. In order this to happen you need add some simple configurations:
First add a contentNegotiationManager into your spring config file. It is responsible for negotiating the response type:

<bean id="contentNegotiationManager"
      class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
    <property name="favorPathExtension" value="false" />
    <property name="favorParameter" value="true" />
    <property name="ignoreAcceptHeader" value="true" />
    <property name="useJaf" value="false" />
     <property name="defaultContentType" value="application/json" />

      <property name="mediaTypes">
         <map>
            <entry key="json" value="application/json" />
            <entry key="xml" value="application/xml" />
         </map>
      </property>
   </bean>

   <mvc:annotation-driven
      content-negotiation-manager="contentNegotiationManager" />

   <context:annotation-config />

Then add Jackson2 jars (jackson-databind and jackson-core) in the service's class path. Jackson is responsible for the data serialization to JSON. Spring will detect these and initialize the MappingJackson2HttpMessageConverter automatically for you. Having only this configured I have my automatic conversion to JSON working. The described config has an additional benefit of giving you the possibility to serialize to XML if you set accept:application/xml header.

There's a way to access this information through the GitHub API.

• Syntax: GET /repos/:user/:repo
• Example: https://api.github.com/repos/git/git

When retrieving information about a repository, a property named size is valued with the size of the whole repository (including all of its history), in kilobytes.

For instance, the Git repository weights around 124 MB. The size property of the returned JSON payload is valued to 124283.

Update

The size is indeed expressed in kilobytes based on the disk usage of the server-side bare repository. However, in order to avoid wasting too much space with repositories with a large network, GitHub relies on Git Alternates. In this configuration, calculating the disk usage against the bare repository doesn't account for the shared object store and thus returns an "incomplete" value through the API call.

This information has been given by GitHub support.

i don't see any for loop to initalize the variables.you can do something like this.

for(i=0;i<50;i++){
 /* Code which is necessary with a simple if statement*/

   }

If the 'Cool Options' are hidden from the view before the field is focused then you would want to create this in JQuery instead of having it in the DOM so anyone using a screen reader wouldn't see unnecessary information. Why should they have to listen to it when we don't have to see it?

So you can setup variables like so:

var $coolOptions= $("<div id='options'></div>").text("Some cool options");

and then append (or prepend) on focus

$("input[name='input_name']").focus(function() {
    $(this).append($coolOptions);
});

and then remove when the focus ends

$("input[name='input_name']").focusout(function() {
    $('#options').remove();
});

If you are using ThreeTen Backport including ThreeTenABP

    Date input = new Date(); // Imagine your Date here
    LocalDate date = DateTimeUtils.toInstant(input)
            .atZone(ZoneId.systemDefault())
            .toLocalDate();

If you are using the backport of JSR 310, either you haven’t got a Date.toInstant() method or it won’t give you the org.threeten.bp.Instant that you need for you further conversion. Instead you need to use the DateTimeUtils class that comes as part of the backport. The remainder of the conversion is the same, so so is the explanation.

In your scenario, you can have a look at asp.net membership, it is good practice to store user's password as hashed string in the database. you can authenticate the user by comparing the hashed incoming password with the one stored in the database.

Everything has been built for this purposes, check out asp.net membership

In SQL server 2012, below can be used

select FORMAT(getdate(), 'MMM yyyy')

This gives exact "Jun 2016"

Trying to make some order:

it all works - all but the firefox bookmarking function. for some reason the 'window.sidebar.addPanel' is not a function for the debugger, though it is working fine.

The problem is that it takes its values from the calling <a ..> tag: title as the bookmark name and href as the bookmark address. so this is my code:

javascript:

$("#bookmarkme").click(function () {
  var url = 'http://' + location.host; // i'm in a sub-page and bookmarking the home page
  var name = "Snir's Homepage";

  if (navigator.userAgent.toLowerCase().indexOf('chrome') > -1){ //chrome
    alert("In order to bookmark go to the homepage and press " 
        + (navigator.userAgent.toLowerCase().indexOf('mac') != -1 ? 
            'Command/Cmd' : 'CTRL') + "+D.")
  } 
  else if (window.sidebar) { // Mozilla Firefox Bookmark
    //important for firefox to add bookmarks - remember to check out the checkbox on the popup
    $(this).attr('rel', 'sidebar');
    //set the appropriate attributes
    $(this).attr('href', url);
    $(this).attr('title', name);

    //add bookmark:
    //  window.sidebar.addPanel(name, url, '');
    //  window.sidebar.addPanel(url, name, '');
    window.sidebar.addPanel('', '', '');
  } 
  else if (window.external) { // IE Favorite
        window.external.addFavorite(url, name);
  } 
  return;
});

html:

  <a id="bookmarkme" href="#" title="bookmark this page">Bookmark This Page</a>

In internet explorer there is a different between 'addFavorite': <a href="javascript:window.external.addFavorite('http://tiny.cc/snir','snir-site')">..</a> and 'AddFavorite': <span onclick="window.external.AddFavorite(location.href, document.title);">..</span>.

example here: http://www.yourhtmlsource.com/javascript/addtofavorites.html

Important, in chrome we can't add bookmarks using js (aspnet-i): http://www.codeproject.com/Questions/452899/How-to-add-bookmark-in-Google-Chrome-Opera-and-Saf

This is commonly caused by running out of file descriptors.

There is the systems total file descriptor limit, what do you get from the command:

sysctl fs.file-nr

This returns counts of file descriptors:

<in_use> <unused_but_allocated> <maximum>

To find out what a users file descriptor limit is run the commands:

sudo su - <username>
ulimit -Hn

To find out how many file descriptors are in use by a user run the command:

sudo lsof -u <username> 2>/dev/null | wc -l

So now if you are having a system file descriptor limit issue you will need to edit your /etc/sysctl.conf file and add, or modify it it already exists, a line with fs.file-max and set it to a value large enough to deal with the number of file descriptors you need and reboot.

fs.file-max = 204708

If you have a circular spring injected dependency it will fail without warning, depending on the level of logging, and a few other factors.

Class A injects Class B, and Class B injects Class A. Via constructor, in this particular case.

As far as I know, a forced update like this is not directly possible. You might be able to reduce the DNS downtime by reducing the TTL (Time-To-Live) value of the entries before changing them, if your name server service provider allows that.

Here's a guide for less painful DNS changes.

A fair warning, though - not all name servers between your client and the authoritative (origin) name server will enforce your TTL, they might have their own caching time.

Based on gkemp answer, On Windows, I found the keystore file path, password, key alias and key password in an earlier log report before I updated Android Studio.

From windows file explorer c:/Users/your pc name/.AndroidStudio1.4 (your android studio version)\system\log\idea.log.1 (or any old log number)

Then I searched for “android.injected.signing.store” and found this from an earlier date:

-Pandroid.injected.signing.store.file= path to your keystore 
-Pandroid.injected.signing.store.password=yourstorepassword
-Pandroid.injected.signing.key.alias=yourkeyalias
-Pandroid.injected.signing.key.password=yourkeypassword

You can also combine RichieHindle's and Ned Batchelder's responses for an average-case O(m+n) algorithm that preserves order:

first_list = [1, 2, 2, 5]
second_list = [2, 5, 7, 9]

fs = set(first_list)
resulting_list = first_list + [x for x in second_list if x not in fs]

assert(resulting_list == [1, 2, 2, 5, 7, 9])

Note that x in s has a worst-case complexity of O(m), so the worst-case complexity of this code is still O(m*n).

No need for jQuery nor regex assuming the character you want to replace exists in the string

Replace last char in a string

str = str.substring(0,str.length-2)+otherchar

Replace last underscore in a string

var pos = str.lastIndexOf('_');
str = str.substring(0,pos) + otherchar + str.substring(pos+1)

or use one of the regular expressions from the other answers

var str1 = "Replace the full stop with a questionmark."_x000D_
var str2 = "Replace last _ with another char other than the underscore _ near the end"_x000D_
_x000D_
// Replace last char in a string_x000D_
_x000D_
console.log(_x000D_
  str1.substring(0,str1.length-2)+"?"_x000D_
)  _x000D_

If you want to use 32-bit references, your heap is limited to 32 GB.

However, if you are willing to use 64-bit references, the size is likely to be limited by your OS, just as it is with 32-bit JVM. e.g. on Windows 32-bit this is 1.2 to 1.5 GB.

Note: you will want your JVM heap to fit into main memory, ideally inside one NUMA region. That's about 1 TB on the bigger machines. If your JVM spans NUMA regions the memory access and the GC in particular will take much longer. If your JVM heap start swapping it might take hours to GC, or even make your machine unusable as it thrashes the swap drive.

Note: You can access large direct memory and memory mapped sizes even if you use 32-bit references in your heap. i.e. use well above 32 GB.

Compressed oops in the Hotspot JVM

Compressed oops represent managed pointers (in many but not all places in the JVM) as 32-bit values which must be scaled by a factor of 8 and added to a 64-bit base address to find the object they refer to. This allows applications to address up to four billion objects (not bytes), or a heap size of up to about 32Gb. At the same time, data structure compactness is competitive with ILP32 mode.

You can use CSS gradient - although there are not consistent across browsers so You would have to code it for every one

VMware experiences a lot of clock drift. This Google search for 'vmware clock drift' links to several articles.

According to the updated syntax, you can use this.myRref.current.focus()

I had some problems to find this option in newer versions, so for Mysql Workbench 6.3, go to schemas and enter in your connection:

Go to Tools -> Data Export

Click on Advanced Options

Scroll down and uncheck extended-inserts

Then export the data you want and you will see the result file as this:

I use this kind of pattern often. It's very compact:

// Define a constant in your class. Use a HashSet for performance
private static final Set<Integer> values = new HashSet<Integer>(Arrays.asList(12, 16, 19));

// In your method:
if (values.contains(x)) {
    ...
}

A HashSet is used here to give good look-up performance - even very large hash sets are able to execute contains() extremely quickly.

If performance is not important, you can code the gist of it into one line:

if (Arrays.asList(12, 16, 19).contains(x))

but know that it will create a new ArrayList every time it executes.

If you need to set a delay of less than a second, it is not necessary to set the .seconds parameter. I hope this is useful to someone.

DispatchQueue.main.asyncAfter(deadline: .now() + 0.5, execute: {

In order to use different settings configuration on different environment, create different settings file. And in your deployment script, start the server using --settings=<my-settings.py> parameter, via which you can use different settings on different environment.

Benefits of using this approach:

1. Your settings will be modular based on each environment

2. You may import the master_settings.py containing the base configuration in the environmnet_configuration.py and override the values that you want to change in that environment.

3. If you have huge team, each developer may have their own local_settings.py which they can add to the code repository without any risk of modifying the server configuration. You can add these local settings to .gitnore if you use git or .hginore if you Mercurial for Version Control (or any other). That way local settings won't even be the part of actual code base keeping it clean.

Omit the property when extending the interface:

interface A {
  a: number;
  b: number;
}

interface B extends Omit<A, 'a'> {
  a: boolean;
}

TypeScript does something similar to what less or sass does for CSS. They are super sets of it, which means that every JS code you write is valid TypeScript code. Plus you can use the other goodies that it adds to the language, and the transpiled code will be valid js. You can even set the JS version that you want your resulting code on.

Currently TypeScript is a super set of ES2015, so might be a good choice to start learning the new js features and transpile to the needed standard for your project.

From Blogging Developer:

In order to understand the difference between keydown and keypress, it is useful to understand the difference between a "character" and a "key". A "key" is a physical button on the computer's keyboard while a "character" is a symbol typed by pressing a button. In theory, the keydown and keyup events represent keys being pressed or released, while the keypress event represents a character being typed. The implementation of the theory is not same in all browsers.

Note: You can also try out the Key Event Tester (available on the above-mentioned site) to understand this concept.

its simple go to the folder where your all java code is saved say E:/javaFolder and then javadoc *.java

When loading a resource make sure you notice the difference between:

getClass().getClassLoader().getResource("com/myorg/foo.jpg") //relative path

and

getClass().getResource("/com/myorg/foo.jpg")); //note the slash at the beginning

I guess, this confusion is causing most of problems when loading a resource.

Also, when you're loading an image it's easier to use getResourceAsStream():

BufferedImage image = ImageIO.read(getClass().getResourceAsStream("/com/myorg/foo.jpg"));

When you really have to load a (non-image) file from a JAR archive, you might try this:

File file = null;
String resource = "/com/myorg/foo.xml";
URL res = getClass().getResource(resource);
if (res.getProtocol().equals("jar")) {
    try {
        InputStream input = getClass().getResourceAsStream(resource);
        file = File.createTempFile("tempfile", ".tmp");
        OutputStream out = new FileOutputStream(file);
        int read;
        byte[] bytes = new byte[1024];

        while ((read = input.read(bytes)) != -1) {

        }
        out.close();
        file.deleteOnExit();
    } catch (IOException ex) {
        Exceptions.printStackTrace(ex);

} else {
    //this will probably work in your IDE, but not from a JAR
    file = new File(res.getFile());

}

After testing many options I've found that the following simple solution is loading the dynamically loaded scripts in the order in which they are added in all modern browsers

loadScripts(sources) {
    sources.forEach(src => {
        var script = document.createElement('script');
        script.src = src;
        script.async = false; //<-- the important part
        document.body.appendChild( script ); //<-- make sure to append to body instead of head 
    });
}

loadScripts(['/scr/script1.js','src/script2.js'])

I also had this problem. I solved it using Trigger/call builds on other projects. For each repository I call the downstream project using parameters.

Main project:

This project is parameterized
String Parameters: PREFIX, MARKETNAME, BRANCH, TAG
Use Custom workspace: ${PREFIX}/${MARKETNAME}
Source code management: None

Then for each repository I call a downstream project like this:

Trigger/call builds on other projects: 
Projects to build: Linux-Tag-Checkout
Current Build Parameters
Predefined Parameters: REPOSITORY=<name>

Downstream project: Linux-Tag-Checkout:

This project is parameterized
String Parameters: PREFIX, MARKETNAME, REPOSITORY, BRANCH, TAG
Use Custom workspace:${PREFIX}/${MARKETNAME}/${REPOSITORY}-${BRANCH}
Source code management: Git
git@<host>:${REPOSITORY}
refspec: +refs/tags/${TAG}:refs/remotes/origin/tags/${TAG}
Branch Specifier: */tags/${TAG} 

To remove .idea/ completely from the git without affecting your IDE config you could just do:

git rm -r --cached '.idea/'
echo .idea >> .gitignore
git commit -am "removed .idea/ directory"

Alternatively to calling plt.show() at the end of the script, you can also control each figure separately doing:

f = plt.figure(1)
plt.hist........
............
f.show()

g = plt.figure(2)
plt.hist(........
................
g.show()

raw_input()

In this case you must call raw_input to keep the figures alive. This way you can select dynamically which figures you want to show

Note: raw_input() was renamed to input() in Python 3

Beware that in Mysql, the utf8 character set is only a subset of the real UTF8 character set. In order to save one byte of storage, the Mysql team decided to store only three bytes of a UTF8 characters instead of the full four-bytes. That means that some east asian language and emoji aren't fully supported. To make sure you can store all UTF8 characters, use the utf8mb4 data type, and utf8mb4_bin or utf8mb4_general_ci in Mysql.

Assuming the expectation is just going to be two windows popping up (one of the parent and one for the popup) then just wait for two windows to come up, find the other window handle and switch to it.

WebElement link = // element that will showModalDialog()

// Click on the link, but don't wait for the document to finish
final JavascriptExecutor executor = (JavascriptExecutor) driver;
executor.executeScript(
    "var el=arguments[0]; setTimeout(function() { el.click(); }, 100);",
  link);

// wait for there to be two windows and choose the one that is 
// not the original window
final String parentWindowHandle = driver.getWindowHandle();
new WebDriverWait(driver, 60, 1000)
    .until(new Function<WebDriver, Boolean>() {
    @Override
    public Boolean apply(final WebDriver driver) {
        final String[] windowHandles =
            driver.getWindowHandles().toArray(new String[0]);
        if (windowHandles.length != 2) {
            return false;
        }
        if (windowHandles[0].equals(parentWindowHandle)) {
            driver.switchTo().window(windowHandles[1]);
        } else {
            driver.switchTo().window(windowHandles[0]);
        }
        return true;
    }
});

Visual Studio 2019 Community 16.3.10
I had similar issue with Release build. Debug build was compiling without any issues. Turns out that the problem was caused by OneDrive. Most likely one could experience similar issues with any backed-up drive or cloud service.

I cleaned everything as per Avi Turner's great answer.

In addition, I manually deleted the \obj\Release -folder from my OneDrive folder and also logged to OneDrive with a browser and deleted the folder there also to prevent OneDrive from loading the cloud version back when compiling.
After that rebuilt and everything worked as should.

I Created this simple program to get HSV Codes in realtime

import cv2
import numpy as np


cap = cv2.VideoCapture(0)

def nothing(x):
    pass
# Creating a window for later use
cv2.namedWindow('result')

# Starting with 100's to prevent error while masking
h,s,v = 100,100,100

# Creating track bar
cv2.createTrackbar('h', 'result',0,179,nothing)
cv2.createTrackbar('s', 'result',0,255,nothing)
cv2.createTrackbar('v', 'result',0,255,nothing)

while(1):

    _, frame = cap.read()

    #converting to HSV
    hsv = cv2.cvtColor(frame,cv2.COLOR_BGR2HSV)

    # get info from track bar and appy to result
    h = cv2.getTrackbarPos('h','result')
    s = cv2.getTrackbarPos('s','result')
    v = cv2.getTrackbarPos('v','result')

    # Normal masking algorithm
    lower_blue = np.array([h,s,v])
    upper_blue = np.array([180,255,255])

    mask = cv2.inRange(hsv,lower_blue, upper_blue)

    result = cv2.bitwise_and(frame,frame,mask = mask)

    cv2.imshow('result',result)

    k = cv2.waitKey(5) & 0xFF
    if k == 27:
        break

cap.release()

cv2.destroyAllWindows()

You can do it programmatically like

InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(editTextField.getWindowToken(), 0);

or set android:windowSoftInputMode="stateHidden" in <activity tag inside AndroidManifest.xml

The original code works fine for reading and separating the csv file data but you need to change the data type from csv to text.

If it's not a big/long array just mirror it:

for( int i = 0; i < arr.length/2; ++i ) 
{ 
  temp = arr[i]; 
  arr[i] = arr[arr.length - i - 1]; 
  arr[arr.length - i - 1] = temp; 
}

In Account controller:

    // POST: /Account/SendVerificationCodeSMS
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public JsonResult SendVerificationCodeSMS(string PhoneNumber)
    {
        return Json(PhoneNumber);
    }

In View:

$.ajax(
{
    url: "/Account/SendVerificationCodeSMS",
    method: "POST",
    contentType: 'application/x-www-form-urlencoded; charset=utf-8',
    dataType: "json",
    data: {
        PhoneNumber: $('[name="PhoneNumber"]').val(),
        __RequestVerificationToken: $('[name="__RequestVerificationToken"]').val()
    },
    success: function (data, textStatus, jqXHR) {
        if (textStatus == "success") {
            alert(data);
            // Do something on page
        }
        else {
            // Do something on page
        }
    },
    error: function (jqXHR, textStatus, errorThrown) {
        console.log(textStatus);
        console.log(jqXHR.status);
        console.log(jqXHR.statusText);
        console.log(jqXHR.responseText);
    }
});

It is important to set contentType to 'application/x-www-form-urlencoded; charset=utf-8' or just omit contentTypefrom the object ...

I'm late to the party, but this solution worked for me quite well. Based on this library, you can use a function lik this - setting the image, quality, max-width, and output format (jepg,png):

function compress(source_img_obj, quality, maxWidth, output_format){
    var mime_type = "image/jpeg";
    if(typeof output_format !== "undefined" && output_format=="png"){
        mime_type = "image/png";
    }

    maxWidth = maxWidth || 1000;
    var natW = source_img_obj.naturalWidth;
    var natH = source_img_obj.naturalHeight;
    var ratio = natH / natW;
    if (natW > maxWidth) {
        natW = maxWidth;
        natH = ratio * maxWidth;
    }

    var cvs = document.createElement('canvas');
    cvs.width = natW;
    cvs.height = natH;

    var ctx = cvs.getContext("2d").drawImage(source_img_obj, 0, 0, natW, natH);
    var newImageData = cvs.toDataURL(mime_type, quality/100);
    var result_image_obj = new Image();
    result_image_obj.src = newImageData;
    return result_image_obj;
}

size_t and int are not interchangeable. For instance on 64-bit Linux size_t is 64-bit in size (i.e. sizeof(void*)) but int is 32-bit.

Also note that size_t is unsigned. If you need signed version then there is ssize_t on some platforms and it would be more relevant to your example.

As a general rule I would suggest using int for most general cases and only use size_t/ssize_t when there is a specific need for it (with mmap() for example).

You can use the built-in http module to do an http.request().

However if you want to simplify the API you can use a module such as superagent

I've been using @AndrewMarshall answer for a long time, but found some edge cases. The following tests doesn't pass:

equals(roundUp(9.69545, 4), 9.6955);
equals(roundUp(37.760000000000005, 4), 37.76);
equals(roundUp(5.83333333, 4), 5.8333);

Here is what I now use to have round up behave correctly:

  function decimalAdjust(type, value, exp) {
    // If the exp is undefined or zero...
    if (typeof exp === 'undefined' || +exp === 0) {
      return Math[type](value);
    }
    value = +value;
    exp = +exp;
    // If the value is not a number or the exp is not an integer...
    if (isNaN(value) || !(typeof exp === 'number' && exp % 1 === 0)) {
      return NaN;
    }
    // If the value is negative...
    if (value < 0) {
      return -decimalAdjust(type, -value, exp);
    }
    // Shift
    value = value.toString().split('e');
    value = Math[type](+(value[0] + 'e' + (value[1] ? (+value[1] - exp) : -exp)));

The answer to this other question shows you how to do that: Javascript equivalent of Python's locals()?

Basically, you can say

window["foo"](arg1, arg2);

or as many others have suggested, you can just use eval:

eval(fname)(arg1, arg2);

although this is extremely unsafe unless you're absolutely sure about what you're eval-ing.

If you are using GitHub for Windows or Mac then now they have a one-click feature to update forks:

1. Select the repository in the UI.
2. Click "Update from user/branch" button the top.

Since there is the [vba] tag, split is also easy:

str1 = "001 baseball"
str2 = Split(str1)

Then use str2(1).

Updated working method

My minSdkversion is 21, so I'm using ContextCompat.checkSelfPermission() method to grant permissions apart from also adding the <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> in manifest. Thus, to get rid of the NullPointerException in spite of having files in your targeted directory, grant permissions as follows:-

MainActivity.java

public class MainActivity extends AppCompatActivity {
    /*Other variables & constants here*/  
    private final int READ_EXTERNAL_STORAGE=100;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // ignore the button code

        Button btn = (Button) findViewById(R.id.button);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                openWebView();
            }
        });
    

         /*---------------------------- GRANT PERMISSIONS START-------------------------*/
        // Main part to grant permission. Handle other cases of permission denied
       //   yourself.
        if(ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED)
            ActivityCompat.requestPermissions(this,new String[] {Manifest.permission.READ_EXTERNAL_STORAGE},READ_EXTERNAL_STORAGE);

         /*---------------------------- GRANT PERMISSIONS OVER-------------------------*/
   }

public void getDownloadedFile() {
        String path = Environment.getExternalStorageDirectory().toString()+"/Download/";
        Log.d("Files", "Path: " + path);
        File directory = new File(path);
        File[] files = directory.listFiles();
        if(directory.canRead() && files!=null) {
            Log.d("Files", "Size: " + files.length);
            for(File file: files)
                Log.d("FILE",file.getName());
        }
        else
            Log.d("Null?", "it is null");
    }

If your object contains a set of data you want to bind your object's iter to, you can cheat and do this:

>>> class foo:
    def __init__(self, *params):
           self.data = params
    def __iter__(self):
        if hasattr(self.data[0], "__iter__"):
            return self.data[0].__iter__()
        return self.data.__iter__()
>>> d=foo(6,7,3,8, "ads", 6)
>>> for i in d:
    print i
6
7
3
8
ads
6

I met a similar problem.But the error report is about

[SSL: TLSV1_ALERT_ACCESS_DENIED] tlsv1 alert access denied (_ssl.c:777)

First I tried this https://python-forum.io/Thread-All-pip-install-attempts-are-met-with-SSL-error#pid_28035 ,but seems it couldn't solve my problems,and still repeat the same issue.

And Second if you are working on a business computer,generally it may exist a web content filter(but I can access https://pypi.python.org through browser directly).And solve this issue by adding a proxy server.

For windows,open the Internet properties through IE or Chrome or whatsoever ,then set valid proxy address and port,and this way solve my problems

Or just adding the option pip --proxy [proxy-address]:port install mitmproxy.But you always need to add this option while installing by pypi

The above two solution is alternative for you demand.

You can get the type of "T" from any collection type that implements IEnumerable<T> with the following:

public static Type GetCollectionItemType(Type collectionType)
{
    var types = collectionType.GetInterfaces()
        .Where(x => x.IsGenericType 
            && x.GetGenericTypeDefinition() == typeof(IEnumerable<>))
        .ToArray();
    // Only support collections that implement IEnumerable<T> once.
    return types.Length == 1 ? types[0].GetGenericArguments()[0] : null;
}

Note that it doesn't support collection types that implement IEnumerable<T> twice, e.g.

public class WierdCustomType : IEnumerable<int>, IEnumerable<string> { ... }

I suppose you could return an array of types if you needed to support this...

Also, you might also want to cache the result per collection type if you're doing this a lot (e.g. in a loop).

adb shell
am start -n com.package.name/com.package.name.ActivityName

Or you can use this directly:

adb shell am start -n com.package.name/com.package.name.ActivityName

You can also specify actions to be filter by your intent-filters:

am start -a com.example.ACTION_NAME -n com.package.name/com.package.name.ActivityName

Maybe this can help you ? git-diff-tree - Compares the content and mode of blobs found via two tree objects

There are overloads of ActionLink which take a fragment parameter. Passing "section12" as your fragment will get you the behavior you're after.

For example, calling LinkExtensions.ActionLink Method (HtmlHelper, String, String, String, String, String, String, Object, Object):

<%= Html.ActionLink("Link Text", "Action", "Controller", null, null, "section12-the-anchor", new { categoryid = "blah"}, null) %>

Today i have found same issue /FILE_NAME/ is not a working copy in morning and i have spent more then two hours to solve it. After long of RND and Google i found some solution and that is CHECKOUT.

1. CHECKOUT from SUBVERSION to local as new project.
2. Change some of code in java file and COMMIT the project.
3. It's Works for me.

Hope it will helpful for you.

There is a lateinit improvement in Kotlin 1.2 that allows to check the initialization state of lateinit variable directly:

lateinit var file: File    

if (this::file.isInitialized) { ... }

See the annoucement on JetBrains blog or the KEEP proposal.

UPDATE: Kotlin 1.2 has been released. You can find lateinit enhancements here:

• Checking whether a lateinit var is initialized
• Lateinit top-level properties and local variables

I don't know what's wrong with yours but one thing for sure is you need to call AES_set_decrypt_key() before decrypting the message. Also don't try to print out as %s because the encrypted message isn't composed by ascii characters anymore.. For example:

static const unsigned char key[] = {
    0x00, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77,
    0x88, 0x99, 0xaa, 0xbb, 0xcc, 0xdd, 0xee, 0xff,
    0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07,
    0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f
};

int main()
{
    unsigned char text[]="hello world!";
    unsigned char enc_out[80];
    unsigned char dec_out[80];

    AES_KEY enc_key, dec_key;

    AES_set_encrypt_key(key, 128, &enc_key);
    AES_encrypt(text, enc_out, &enc_key);      

    AES_set_decrypt_key(key,128,&dec_key);
    AES_decrypt(enc_out, dec_out, &dec_key);

    int i;

    printf("original:\t");
    for(i=0;*(text+i)!=0x00;i++)
        printf("%X ",*(text+i));
    printf("\nencrypted:\t");
    for(i=0;*(enc_out+i)!=0x00;i++)
        printf("%X ",*(enc_out+i));
    printf("\ndecrypted:\t");
    for(i=0;*(dec_out+i)!=0x00;i++)
        printf("%X ",*(dec_out+i));
    printf("\n");

    return 0;
} 

U1: your key is 192 bit isn't it...

You can try these lines:

$("#DynamicValueAssignedHere .formdiv form").contents().find("input[name='FirstName']").prevObject[1].value

Other answers seem a bit complex, you can just add a parameter 'label' in scatter function and that will be the legend for your plot.

import matplotlib.pyplot as plt
from numpy.random import random

colors = ['b', 'c', 'y', 'm', 'r']

lo = plt.scatter(random(10), random(10), marker='x', color=colors[0],label='Low Outlier')
ll = plt.scatter(random(10), random(10), marker='o', color=colors[0],label='LoLo')
l  = plt.scatter(random(10), random(10), marker='o', color=colors[1],label='Lo')
a  = plt.scatter(random(10), random(10), marker='o', color=colors[2],label='Average')
h  = plt.scatter(random(10), random(10), marker='o', color=colors[3],label='Hi')
hh = plt.scatter(random(10), random(10), marker='o', color=colors[4],label='HiHi')
ho = plt.scatter(random(10), random(10), marker='x', color=colors[4],label='High Outlier')

plt.legend(loc='upper center', bbox_to_anchor=(0.5, -0.05),
          fancybox=True, shadow=True, ncol=4)

plt.show()

This is your output:

I had a similar error but with different context when I uploaded a *.p file to Google Drive. I tried to use it later in a Google Colab session, and got this error:

    1 with open("/tmp/train.p", mode='rb') as training_data:
----> 2     train = pickle.load(training_data)
UnpicklingError: invalid load key, '<'.

I solved it by compressing the file, upload it and then unzip on the session. It looks like the pickle file is not saved correctly when you upload/download it so it gets corrupted.

the root of this question is how to decode bytes to string?

this can be done with the JAVA NIO CharSet:

public final CharBuffer decode(ByteBuffer bb)

FileChannel channel = FileChannel.open(
  Paths.get("files/text-latin1.txt", StandardOpenOption.READ);
ByteBuffer buffer = ByteBuffer.allocate(1024);
channel.read(buffer);

CharSet latin1 = StandardCharsets.ISO_8859_1;
CharBuffer latin1Buffer = latin1.decode(buffer);

String result = new String(latin1Buffer.array());

• First we create a channel and read it in a buffer
• Then decode method decodes a Latin1 buffer to a char buffer
• We can then put the result, for instance, in a String

Finally, with Java 9+ it is possible with ProcessHandle:

public static void main(String[] args) {
    ProcessHandle.allProcesses()
            .forEach(process -> System.out.println(processDetails(process)));
}

private static String processDetails(ProcessHandle process) {
    return String.format("%8d %8s %10s %26s %-40s",
            process.pid(),
            text(process.parent().map(ProcessHandle::pid)),
            text(process.info().user()),
            text(process.info().startInstant()),
            text(process.info().commandLine()));
}

private static String text(Optional<?> optional) {
    return optional.map(Object::toString).orElse("-");
}

Output:

    1        -       root   2017-11-19T18:01:13.100Z /sbin/init
  ...

Another way is to use tidy evaluation approach. It is pretty straightforward to pass columns of a data frame either as strings or bare column names. See more about tidyeval here.

library(rlang)
library(tidyverse)

set.seed(123)
df <- data.frame(B = rnorm(10), D = rnorm(10))

Use column names as strings

fun3 <- function(x, ...) {
  # capture strings and create variables
  dots <- ensyms(...)
  # unquote to evaluate inside dplyr verbs
  summarise_at(x, vars(!!!dots), list(~ max(., na.rm = TRUE)))
}

fun3(df, "B")
#>          B
#> 1 1.715065

fun3(df, "B", "D")
#>          B        D
#> 1 1.715065 1.786913

Use bare column names

fun4 <- function(x, ...) {
  # capture expressions and create quosures
  dots <- enquos(...)
  # unquote to evaluate inside dplyr verbs
  summarise_at(x, vars(!!!dots), list(~ max(., na.rm = TRUE)))
}

fun4(df, B)
#>          B
#> 1 1.715065

fun4(df, B, D)
#>          B        D
#> 1 1.715065 1.786913

Assuming:

• You want 4 column grid layout with wrapping
• The number of items is not necessarily a multiple of 4

Set a left margin on every item except 1st, 5th and 9th item and so on. If the left margin is 10px then each row will have 30px margin distributed among 4 items. The percentage width for item is calculated as follows:

100% / 4 - horizontal-border - horizontal-padding - left-margin * (4 - 1) / 4

This is a decent workaround for issues involving last row of flexbox.

.flex {_x000D_
  display: flex;_x000D_
  flex-direction: row;_x000D_
  flex-wrap: wrap;_x000D_
  margin: 1em 0 3em;_x000D_
  background-color: peachpuff;_x000D_
}_x000D_
_x000D_
.item {_x000D_
  margin-left: 10px;_x000D_
  border: 1px solid;_x000D_
  padding: 10px;_x000D_
  width: calc(100% / 4 - 2px - 20px - 10px * (4 - 1) / 4);_x000D_
  background-color: papayawhip;_x000D_
}_x000D_
_x000D_
.item:nth-child(4n + 1) {_x000D_
  margin-left: 0;_x000D_
}_x000D_
_x000D_
.item:nth-child(n + 5) {_x000D_
  margin-top: 10px;_x000D_
}

<div class="flex">_x000D_
  <div class="item">1</div>_x000D_
  <div class="item">2</div>_x000D_
  <div class="item">3</div>_x000D_
  <div class="item">4</div>_x000D_
</div>_x000D_
<div class="flex">_x000D_
  <div class="item">1</div>_x000D_
  <div class="item">2</div>_x000D_
  <div class="item">3</div>_x000D_
  <div class="item">4</div>_x000D_
  <div class="item">5</div>_x000D_
  <div class="item">6</div>_x000D_
</div>_x000D_
<div class="flex">_x000D_
  <div class="item">1</div>_x000D_
  <div class="item">2</div>_x000D_
  <div class="item">3</div>_x000D_
  <div class="item">4</div>_x000D_
  <div class="item">5</div>_x000D_
  <div class="item">6</div>_x000D_
  <div class="item">7</div>_x000D_
  <div class="item">8</div>_x000D_
  <div class="item">9</div>_x000D_
</div>

To create a vertical line centered inside a div I think you can use this code. The 'container' may well be 100% width, I guess.

div.container {_x000D_
  width: 400px;_x000D_
}_x000D_
_x000D_
div.vertical-line {_x000D_
  border-left: 1px solid #808080;_x000D_
  height: 350px;_x000D_
  margin-left: auto;_x000D_
  margin-right: auto;_x000D_
  width: 1px;_x000D_
}

<div class="container">_x000D_
  <div class="vertical-line">&nbsp;</div>_x000D_
</div>

Note as of Symfony 3.3 EntityManager is depreciated. Use EntityManagerInterface instead.

namespace AppBundle\Service;

use Doctrine\ORM\EntityManagerInterface;

class Someclass {
    protected $em;

    public function __construct(EntityManagerInterface $entityManager)
    {
        $this->em = $entityManager;
    }

    public function somefunction() {
        $em = $this->em;
        ...
    }
}

The query below will result in dd-mmm-yy format.

select 
cast(DAY(getdate()) as varchar)+'-'+left(DATEname(m,getdate()),3)+'-'+  
Right(Year(getdate()),2)

After more exploration and testing, it appears that this issue was being caused by debugging the plugin and using breakpoints. SVN/Subclipse apparently didn't like having breakpoints midway through their execution and as a result this lock files were being created. As soon as I started just running the plugin, this issue disappeared.

I do that using jQuery

if ( 0 > $.inArray( test, [a,b] ) ) { ... }

You are looking for the update method

dic0.update( dic1 )
print( dic0 ) 

gives

{'dic0': 0, 'dic1': 1}

Since there is a delimiter, you should use that instead of worrying about how long the md5 is.

>>> s = "416d76b8811b0ddae2fdad8f4721ddbe|d4f656ee006e248f2f3a8a93a8aec5868788b927|12a5f648928f8e0b5376d2cc07de8e4cbf9f7ccbadb97d898373f85f0a75c47f"
>>> md5sum, delim, rest = s.partition('|')
>>> md5sum
'416d76b8811b0ddae2fdad8f4721ddbe'

Alternatively

>>> md5sum, sha1sum, sha5sum = s.split('|')
>>> md5sum
'416d76b8811b0ddae2fdad8f4721ddbe'
>>> sha1sum
'd4f656ee006e248f2f3a8a93a8aec5868788b927'
>>> sha5sum
'12a5f648928f8e0b5376d2cc07de8e4cbf9f7ccbadb97d898373f85f0a75c47f'

float is obsolete, better use display: flex;:

example :

.parent-div{ display: flex; }

indicate the direction by flex-direction: row/column;. go down if no space by flex-wrap: wrap/nowrap;

The following should work with the latest version of Apache common codec

byte[] decodedBytes = Base64.getDecoder().decode("YWJjZGVmZw==");
System.out.println(new String(decodedBytes));

and for encoding

byte[] encodedBytes = Base64.getEncoder().encode(decodedBytes);
System.out.println(new String(encodedBytes));

From your config file, it seems like you're only excluding node_modules from being parsed with babel-loader, but not from being bundled.

In order to exclude node_modules and native node libraries from bundling, you need to:

1. Add target: 'node' to your webpack.config.js. This will exclude native node modules (path, fs, etc.) from being bundled.
2. Use webpack-node-externals in order to exclude other node_modules.

So your result config file should look like:

var nodeExternals = require('webpack-node-externals');
...
module.exports = {
    ...
    target: 'node', // in order to ignore built-in modules like path, fs, etc. 
    externals: [nodeExternals()], // in order to ignore all modules in node_modules folder 
    ...
};

I agree that the way to do is to redirect to the new controller in usual cases.

I came across a use case where I needed to display the same page to 2 different kind of users (backend user previewing the page of a frontend user) so in my opinion what I needed was genuinely to call the frontend controller from the backend controller.

I solved the problem by making the frontend method static and wrapping it in another method. Hope it helps!

//==========
// Frontend
//==========
function profile()
{
   //Access check

   //Get profile id
   $id = get_user_id();

   return self::_profile($id);
}

static function _profile($id)
{
   $CI = &get_instance();
   //Prepare page
   //Load view
}

//==========
// Backend
//==========
function preview_profile($id)
{
   $this->load->file('controllers/frontend.php', false);

   Frontend::_profile($id);
}

I'm super late to the party, but this doesn't appear in any of the existing answers:

GROUP BY DATEADD(MINUTE, DATEDIFF(MINUTE, '2000', date_column) / 10 * 10, '2000')

• The 10 and MINUTE terms can be changed to any number and DATEPART, respectively.
• It is a DATETIME value, which means:
  • It works fine across long time intervals. (There is no collision between years.)
  • Including it in the SELECT statement will give your output a column with pretty output truncated at the level you specify.
• '2000' is an "anchor date" around which SQL will perform the date math. Jereonh discovered below that you encounter an integer overflow with the previous anchor (0) when you group recent dates by seconds or milliseconds.^†

SELECT   DATEADD(MINUTE, DATEDIFF(MINUTE, '2000', aa.[date]) / 10 * 10, '2000')
                                                               AS [date_truncated],
         COUNT(*) AS [records_in_interval],
         AVG(aa.[value]) AS [average_value]
FROM     [friib].[dbo].[archive_analog] AS aa
GROUP BY DATEADD(MINUTE, DATEDIFF(MINUTE, '2000', aa.[date]) / 10 * 10, '2000')
ORDER BY [date_truncated]

If your data spans centuries,^‡ using a single anchor date for second- or millisecond grouping will still encounter the overflow. If that is happening, you can ask each row to anchor the binning comparison to its own date's midnight:

• Use DATEADD(DAY, DATEDIFF(DAY, 0, aa.[date]), 0) instead of '2000' wherever it appears above. Your query will be totally unreadable, but it will work.

• An alternative might be CONVERT(DATETIME, CONVERT(DATE, aa.[date])) as the replacement.

_{^† 2³² ˜ 4.29E+9, so if your DATEPART is SECOND, you get 4.3 billion seconds on either side, or "anchor ± 136 years." Similarly, 2³² milliseconds is ˜ 49.7 days.
^‡ If your data actually spans centuries or millenia and is still accurate to the second or millisecond… congratulations! Whatever you're doing, keep doing it.}

Add System.Web.Extensions as a reference to your project

For Ref.

LinkedHashMap is precisely what you're looking for.

It is exactly like HashMap, except that when you iterate over it, it presents the items in the insertion order.

I'd recommend to use an array for storing all values via __set().

class foo {

    protected $values = array();

    public function __get( $key )
    {
        return $this->values[ $key ];
    }

    public function __set( $key, $value )
    {
        $this->values[ $key ] = $value;
    }

}

This way you make sure, that you can't access the variables in another way (note that $values is protected), to avoid collisions.

var datos = $("#id_formulario").serialize();
$.ajax({         
    url: "url.php",      
    type: "POST",                   
    dataType: "html",                 
    data: datos,                 
    success: function (prueba) { 
        alert("funciona!");
    }//FIN SUCCES

});//FIN  AJAX

It's fatal. The remote server has sent you a RST packet, which indicates an immediate dropping of the connection, rather than the usual handshake. This bypasses the normal half-closed state transition. I like this description:

"Connection reset by peer" is the TCP/IP equivalent of slamming the phone back on the hook. It's more polite than merely not replying, leaving one hanging. But it's not the FIN-ACK expected of the truly polite TCP/IP converseur.

I used this more concisely :

var sys = require('sys')
var exec = require('child_process').exec;
function puts(error, stdout, stderr) { sys.puts(stdout) }
exec("ls -la", puts);

it works perfectly. :)

How about this EXAMPLE? It seems straightforward.

final EditText txtUrl = new EditText(this);

// Set the default text to a link of the Queen
txtUrl.setHint("http://www.librarising.com/astrology/celebs/images2/QR/queenelizabethii.jpg");

new AlertDialog.Builder(this)
  .setTitle("Moustachify Link")
  .setMessage("Paste in the link of an image to moustachify!")
  .setView(txtUrl)
  .setPositiveButton("Moustachify", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
      String url = txtUrl.getText().toString();
      moustachify(null, url);
    }
  })
  .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
    }
  })
  .show(); 

I got this from YouTube Setting up Python Visual Studio Code... Venv

OK, the video really didn't help me all that much, but... the first comment under (by the person who posted the video) makes a lot of sense and is pure gold.

Basically, open up Visual Studio Code' built-in Terminal. Then source <your path>/activate.sh, the usual way you choose a venv from the command line. I have a predefined Bash function to find & launch the right script file and that worked just fine.

Quoting that YouTube comment directly (all credit to aneuris ap):

(you really only need steps 5-7)

1. Open your command line/terminal and type `pip virtualenv`.
2. Create a folder in which the virtualenv will be placed in.
3. 'cd' to the script folder in the virtualenv and run activate.bat (CMD).
4. Deactivate to turn of the virtualenv (CMD).
5. Open the project in Visual Studio Code and use its built-in terminal to 'cd' to the script folder in you virtualenv.
6. Type source activates (in Visual Studio Code I use the Git terminal).
7. Deactivate to turn off the virtualenv.

As you may notice, he's talking about activate.bat. So, if it works for me on a Mac, and it works on Windows too, chances are it's pretty robust and portable.

print("Hello, World!")

You are probably using Python 3.0, where print is now a function (hence the parenthesis) instead of a statement.

#!/bin/bash

req=$(curl -s -X GET http://host:8080/some/resource -H "Accept: application/json") 2>&1
echo "${req}"

Now it's pretty easy to implement for RecyclerView with ItemTouchHelper. Just override onMove method from ItemTouchHelper.Callback:

 @Override
public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
    mMovieAdapter.swap(viewHolder.getAdapterPosition(), target.getAdapterPosition());
    return true;
}

Pretty good tutorial on this can be found at medium.com : Drag and Swipe with RecyclerView

Connect to your server via SSH

then connect to your mysql console

and

USE user_base
REPAIR TABLE TABLE;

-OR-

If there are a lot of broken tables in current database:

mysqlcheck -uUSER -pPASSWORD  --repair --extended user_base

If there are a lot of broken tables in a lot of databases:

mysqlcheck -uUSER -pPASSWORD  --repair --extended -A

The easiest solution is the first one of your examples:

<a href="#link" class="btn btn-info" role="button">Link Button</a>

The reason it's not working for you is most likely, as you say, a problem in the theme you're using. There is no reason to resort to bloated extra markup or inline Javascript for this.

As an alternative, you might use a 9 patch image as the background for your layout, allowing for more "natural" shadows:

Result:

Put the image in your /res/drawable folder.
Make sure the file extension is .9.png, not .png

By the way, this is a modified (reduced to the minimum square size) of an existing resource found in the API 19 sdk resources folder.
I left the red markers, since they don't seem to be harmful, as shown in the draw9patch tool.

[EDIT]

About 9 patches, in case you never had anything to do with them.

Simply add it as the background of your View.

The black-marked areas (left and top) will stretch (vertically, horizontally).
The black-marked areas (right, bottom) define the "content area" (where it's possible to add text or Views - you can call the unmarked regions "padding", if you like to).

Here is a post which introduces different types of keystore in Java and the differences among different types of keystore. http://www.pixelstech.net/article/1408345768-Different-types-of-keystore-in-Java----Overview

Below are the descriptions of different keystores from the post:

JKS, Java Key Store. You can find this file at sun.security.provider.JavaKeyStore. This keystore is Java specific, it usually has an extension of jks. This type of keystore can contain private keys and certificates, but it cannot be used to store secret keys. Since it's a Java specific keystore, so it cannot be used in other programming languages.

JCEKS, JCE key store. You can find this file at com.sun.crypto.provider.JceKeyStore. This keystore has an extension of jceks. The entries which can be put in the JCEKS keystore are private keys, secret keys and certificates.

PKCS12, this is a standard keystore type which can be used in Java and other languages. You can find this keystore implementation at sun.security.pkcs12.PKCS12KeyStore. It usually has an extension of p12 or pfx. You can store private keys, secret keys and certificates on this type.

PKCS11, this is a hardware keystore type. It servers an interface for the Java library to connect with hardware keystore devices such as Luna, nCipher. You can find this implementation at sun.security.pkcs11.P11KeyStore. When you load the keystore, you no need to create a specific provider with specific configuration. This keystore can store private keys, secret keys and cetrificates. When loading the keystore, the entries will be retrieved from the keystore and then converted into software entries.

if(!str.trim()){
  console.log('string is empty or only contains spaces');
}

Removing the whitespace from a string can be done using String#trim().

To check if a string is null or undefined, one can check if the string itself is falsey, in which case it is null, undefined, or an empty string. This first check is necessary, as attempting to invoke methods on null or undefined will result in an error. To check if it contains only spaces, one can check if the string is falsey after trimming, which means that it is an empty string at that point.

if(!str || !str.trim()){
   //str is null, undefined, or contains only spaces
}

This can be simplified using the optional chaining operator.

if(!str?.trim()){
   //str is null, undefined, or contains only spaces
}

If you are certain that the variable will be a string, only the second check is necessary.

if(!str.trim()){
   console.log("str is empty or contains only spaces");
}

Using Math.Round():

int percentComplete = (int)Math.Round((double)(100 * complete) / total);

or manually rounding:

int percentComplete = (int)(0.5f + ((100f * complete) / total));

API 29.+ usage AndroidX libraries. If you are using API 29.+, then you cannot remove these. If you want to remove AndroidX, then you need to remove the entire 29.+ API from your SDK:

This will work fine.

First install pylint-django using following command

$ pip install pylint-django

Then run the second command as follows:

$ pylint test_file.py --load-plugins pylint_django

--load-plugins pylint_django is necessary for correctly review a code of django

The issue was in fact that one of the properties was a relation to another table. I changed my LINQ query so that it could get the same data from a different method without needing to load the entire table.

Thank you all for your help!

On linux sdcard image is located in:

~/.android/avd/<avd name>.avd/sdcard.img

You can mount it for example with (assuming /mnt/sdcard is existing directory):

sudo mount sdcard.img -o loop /mnt/sdcard

To install apk file use adb:

adb install your_app.apk

In addition to the headers consider serving your page via https. Many browsers will not cache https by default.

this is basically happens because your tables are in two different charsets. as a example one table created in charset=utf-8 and other tables is created in CHARSET=latin1 so you want be able add foriegn key to these tables. use same charset in both tables then you will be able to add foriegn keys. error 1005 foriegn key constraint incorrectly formed can resolve from this

Hi I got this error because I left out the ampersand (&) in

To trigger a search every time the enter key is pressed, use this:

$(document).keypress(function(event) {
    var keycode = (event.keyCode ? event.keyCode : event.which);
    if (keycode == '13') {
        $('#btnSearch').click();
    }
}

If you are using Vue you can also use v.model.lazy instead of debounce but remember v.model.lazy will not always work as Vue limits it for custom components.

For custom components you should use :value along with @change.native

<b-input :value="data" @change.native="data = $event.target.value" ></b-input>

You can use white-space:pre-wrap on the tooltip. This will make the tooltip respect new lines. Lines will still wrap if they are longer than the default max-width of the container.

.tooltip-inner {
    white-space:pre-wrap;
}

http://jsfiddle.net/chad/TSZSL/52/

If you want to prevent text from wrapping, do the following instead.

.tooltip-inner {
    white-space:pre;
    max-width:none;
}

http://jsfiddle.net/chad/TSZSL/53/

Neither of these will work with a \n in the html, they must actually be actual newlines. Alternatively, you can use encoded newlines 
, but that's probably even less desirable than using <br>'s.

You should use NULL only with pointers. Your function accepts a reference and they can't be NULL.

Write your function just like you would write it in C.

I had the same problem, and the solution ended up being adding my local machine's IP to the list of inbound rules in the active security group. In the inbound dialog below, enter 22 in the port range, your local IP/32 in the source field, and leave 'custom tcp rule' in the dropdown.

Major difference:

Calling print will immediately make your program write out text for you to see. Use print when you want to show a value to a human.

return is a keyword. When a return statement is reached, Python will stop the execution of the current function, sending a value out to where the function was called. Use return when you want to send a value from one point in your code to another.

Using return changes the flow of the program. Using print does not.

There are few modes to open file (read, write etc..)

If you want to read from file you should type file = open("File.txt","r"), if write than file = open("File.txt","w"). You need to give the right permission regarding your usage.

more modes:

• r. Opens a file for reading only.
• rb. Opens a file for reading only in binary format.
• r+ Opens a file for both reading and writing.
• rb+ Opens a file for both reading and writing in binary format.
• w. Opens a file for writing only.
• you can find more modes in here

Yes. you can use SimpleDateFormat like this.

SimpleDateFormat formatter, FORMATTER;
formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
String oldDate = "2011-03-10T11:54:30.207Z";
Date date = formatter.parse(oldDate.substring(0, 24));
FORMATTER = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss.SSS");
System.out.println("OldDate-->"+oldDate);
System.out.println("NewDate-->"+FORMATTER.format(date));

Output OldDate-->2011-03-10T11:54:30.207Z NewDate-->10-Mar-2011 11:54:30.207

I would go with x.equals(y) because that's consistent way to check equality for all classes.

As far as performance goes, equals is actually more expensive because it ends up calling intValue().

EDIT: You should avoid autoboxing in most cases. It can get really confusing, especially the author doesn't know what he was doing. You can try this code and you will be surprised by the result;

Integer a = 128;
Integer b = 128;

System.out.println(a==b);

1. Local variables are located on the stack. Heap space is occupied by objects.

2. You can use the -Xmx option.

3. Basically heap space is used up everytime you allocate a new object with new and freed some time after the object is no longer referenced. So make sure that you don't keep references to objects that you no longer need.

the root directory (in PHP) is the directory of the file that is pinged. For example, I go to http://localhost/directory/to/file/index.php, the root directory will be "/dictory/to/file", since it's the one that you've made a web request for.

It gets very simple if you think it as two vectors, one from point P1 to P2 and one from P1 to P3

so:
a = (p1.x - p2.x, p1.y - p2.y)
b = (p1.x - p3.x, p1.y - p3.y)

You can then invert the dot product formula:

to get the angle:

Remember that just means: a1*b1 + a2*b2 (just 2 dimensions here...)

Actually, I think the problem is that your variable "lines" is bad. You defined lines as a tuple, but I believe that write() requires a string. All you have to change is your commas into pluses (+).

nl = "\n"
lines = line1+nl+line2+nl+line3+nl
textdoc.writelines(lines)

should work.

Uses Line Feeds and spaces as a good break point:

declare @sqlAll as nvarchar(max)
set @sqlAll = '-- Insert all your sql here'

print '@sqlAll - truncated over 4000'
print @sqlAll
print '   '
print '   '
print '   '

print '@sqlAll - split into chunks'
declare @i int = 1, @nextspace int = 0, @newline nchar(2)
set @newline = nchar(13) + nchar(10)


while Exists(Select(Substring(@sqlAll,@i,3000))) and (@i < LEN(@sqlAll))
begin
    while Substring(@sqlAll,@i+3000+@nextspace,1) <> ' ' and Substring(@sqlAll,@i+3000+@nextspace,1) <> @newline
    BEGIN
        set @nextspace = @nextspace + 1
    end
    print Substring(@sqlAll,@i,3000+@nextspace)
    set @i = @i+3000+@nextspace
    set @nextspace = 0
end
print '   '
print '   '
print '   '

>>> print "{:.2f}".format(1.123456)
1.12

You can change 2 in 2f to any number of decimal points you want to show.

EDIT:

From Python3.6, this translates to:

>>> print(f"{1.1234:.2f}")
1.12

You can revert by migrating to the previous migration.

For example use below command:

./manage.py migrate example_app one_left_to_the_last_migration

then delete last_migration file.

Solution

Angular2 developed on the ground of modern technologies like TypeScript and ES6.

So you can just do let copy = Object.assign({}, myObject).

Object assign - nice examples.

For nested objects : let copy = JSON.parse(JSON.stringify(myObject))

I just had a very similar issue with the added problem that I needed to create download links to files inside a ZIP file.

I first tried to create a temporary file, then provided a link to the temporary file, but I found that some browsers would just display the contents (a CSV Excel file) rather than offering to download. Eventually I found the solution by using a servlet. It works both on Tomcat and GlassFish, and I tried it on Internet Explorer 10 and Chrome.

The servlet takes as input a full path name to the ZIP file, and the name of the file inside the zip that should be downloaded.

Inside my JSP file I have a table displaying all the files inside the zip, with links that say: onclick='download?zip=<%=zip%>&csv=<%=csv%>'

The servlet code is in download.java:

package myServlet;

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.zip.*;
import java.util.*;

// Extend HttpServlet class
public class download extends HttpServlet {

    public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException
    {
        PrintWriter out = response.getWriter(); // now we can write to the client

        String filename = request.getParameter("csv");
        String zipfile = request.getParameter("zip");

        String aLine = "";

        response.setContentType("application/x-download");
        response.setHeader( "Content-Disposition", "attachment; filename=" + filename); // Force 'save-as'
        ZipFile zip = new ZipFile(zipfile);
        for (Enumeration e = zip.entries(); e.hasMoreElements();) {
            ZipEntry entry = (ZipEntry) e.nextElement();
            if(entry.toString().equals(filename)) {
                InputStream is = zip.getInputStream(entry);
                BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"), 65536);
                while ((aLine = br.readLine()) != null) {
                    out.println(aLine);
                }
                is.close();
                break;
            }
        }
    }
}

To compile on Tomcat you need the classpath to include tomcat\lib\servlet-api.jar or on GlassFish: glassfish\lib\j2ee.jar

But either one will work on both. You also need to set your servlet in web.xml.

<> is used to indicate generics in Java.

T is a type parameter in this example. And no: instantiating is one of the few things that you can't do with T.

Apart from the tutorial linked above Angelika Langers Generics FAQ is a great resource on the topic.

Variable names in PHP start with $ so $entryId is the name of a variable. $this is a special variable in Object Oriented programming in PHP, which is reference to current object. -> is used to access an object member (like properties or methods) in PHP, like the syntax in C++. so your code means this:

Place the value of variable $entryId into the entryId field (or property) of this object.

The & operator in PHP, means pass reference. Here is a example:

$b=2;
$a=$b;
$a=3;
print $a;
print $b;
// output is 32

$b=2;
$a=&$b; // note the & operator
$a=3;
print $a;
print $b;
// output is 33

In the above code, because we used & operator, a reference to where $b is pointing is stored in $a. So $a is actually a reference to $b.

In PHP, arguments are passed by value by default (inspired by C). So when calling a function, when you pass in your values, they are copied by value not by reference. This is the default IN MOST SITUATIONS. However there is a way to have pass by reference behaviour, when defining a function. Example:

function plus_by_reference( &$param ) {
      // what ever you do, will affect the actual parameter outside the function
      $param++;
}

$a=2;
plus_by_reference( $a );
echo $a;
// output is 3

There are many built-in functions that behave like this. Like the sort() function that sorts an array will affect directly on the array and will not return another sorted array.

There is something interesting to note though. Because pass-by-value mode could result in more memory usage, and PHP is an interpreted language (so programs written in PHP are not as fast as compiled programs), to make the code run faster and minimize memory usage, there are some tweaks in the PHP interpreter. One is lazy-copy (I'm not sure about the name). Which means this:

When you are coping a variable into another, PHP will copy a reference to the first variable into the second variable. So your new variable, is actually a reference to the first one until now. The value is not copied yet. But if you try to change any of these variables, PHP will make a copy of the value, and then changes the variable. This way you will have the opportunity to save memory and time, IF YOU DO NOT CHANGE THE VALUE.

So:

$b=3;
$a=$b;
// $a points to $b, equals to $a=&$b
$b=4;
// now PHP will copy 3 into $a, and places 4 into $b

After all this, if you want to place the value of $entryId into 'entryId' property of your object, the above code will do this, and will not copy the value of entryId, until you change any of them, results in less memory usage. If you actually want them both to point to the same value, then use this:

$this->entryId=&$entryId;

For straight HTML, with no JavaScript required:

<a href="#something">Add '#something' to URL</a>

Or, to take your question more literally, to just add '#' to the URL:

<a href="#">Add '#' to URL</a>

You appear to be trying to mix query expression syntax and "normal" lambda expression syntax. You can either use:

IEnumerable<SelectListItem> stores =
        from store in database.Stores
        where store.CompanyID == curCompany.ID
        select new SelectListItem { Value = store.Name, Text = store.ID};
ViewBag.storeSelector = stores;

Or:

IEnumerable<SelectListItem> stores = database.Stores
        .Where(store => store.CompanyID == curCompany.ID)
        .Select(s => new SelectListItem { Value = s.Name, Text = s.ID});
ViewBag.storeSelector = stores;

You can't mix the two like you're trying to.

First, the enum methods shouldn't be in all caps. They are methods just like other methods, with the same naming convention.

Second, what you are doing is not the best possible way to set up your enum. Instead of using an array of values for the values, you should use separate variables for each value. You can then implement the constructor like you would any other class.

Here's how you should do it with all the suggestions above:

public enum States {
    ...
    MASSACHUSETTS("Massachusetts",  "MA",   true),
    MICHIGAN     ("Michigan",       "MI",   false),
    ...; // all 50 of those

    private final String full;
    private final String abbr;
    private final boolean originalColony;

    private States(String full, String abbr, boolean originalColony) {
        this.full = full;
        this.abbr = abbr;
        this.originalColony = originalColony;
    }

    public String getFullName() {
        return full;
    }

    public String getAbbreviatedName() {
        return abbr;
    }

    public boolean isOriginalColony(){
        return originalColony;
    }
}
