the wmic bios get serialnumber command call the Win32_BIOS wmi class and get the value of the SerialNumber property, which retrieves the serial number of the BIOS Chip of your system.

Basic ViewPager Example

This answer is a simplification of the documentation, this tutorial, and the accepted answer. It's purpose is to get a working ViewPager up and running as quickly as possible. Further edits can be made after that.

XML

Add the xml layouts for the main activity and for each page (fragment). In our case we are only using one fragment layout, but if you have different layouts on the different pages then just make one for each of them.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.verticalviewpager.MainActivity">

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

fragment_one.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent" >

    <TextView
        android:id="@+id/textview"
        android:textSize="30sp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true" />

</RelativeLayout>

Code

This is the code for the main activity. It includes the PagerAdapter and FragmentOne as inner classes. If these get too large or you are reusing them in other places, then you can move them to their own separate classes.

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;

public class MainActivity extends AppCompatActivity {

    static final int NUMBER_OF_PAGES = 2;

    MyAdapter mAdapter;
    ViewPager mPager;

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

        mAdapter = new MyAdapter(getSupportFragmentManager());
        mPager = findViewById(R.id.viewpager);
        mPager.setAdapter(mAdapter);
    }

    public static class MyAdapter extends FragmentPagerAdapter {
        public MyAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public int getCount() {
            return NUMBER_OF_PAGES;
        }

        @Override
        public Fragment getItem(int position) {

            switch (position) {
                case 0:
                    return FragmentOne.newInstance(0, Color.WHITE);
                case 1:
                    // return a different Fragment class here
                    // if you want want a completely different layout
                    return FragmentOne.newInstance(1, Color.CYAN);
                default:
                    return null;
            }
        }
    }

    public static class FragmentOne extends Fragment {

        private static final String MY_NUM_KEY = "num";
        private static final String MY_COLOR_KEY = "color";

        private int mNum;
        private int mColor;

        // You can modify the parameters to pass in whatever you want
        static FragmentOne newInstance(int num, int color) {
            FragmentOne f = new FragmentOne();
            Bundle args = new Bundle();
            args.putInt(MY_NUM_KEY, num);
            args.putInt(MY_COLOR_KEY, color);
            f.setArguments(args);
            return f;
        }

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            mNum = getArguments() != null ? getArguments().getInt(MY_NUM_KEY) : 0;
            mColor = getArguments() != null ? getArguments().getInt(MY_COLOR_KEY) : Color.BLACK;
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            View v = inflater.inflate(R.layout.fragment_one, container, false);
            v.setBackgroundColor(mColor);
            TextView textView = v.findViewById(R.id.textview);
            textView.setText("Page " + mNum);
            return v;
        }
    }
}

Finished

If you copied and pasted the three files above to your project, you should be able to run the app and see the result in the animation above.

Going on

There are quite a few things you can do with ViewPagers. See the following links to get started:

• Creating Swipe Views with Tabs
• ViewPager with FragmentPagerAdapter (CodePath tutorials are always good)

Is your application running as a 64 or 32bit process? You can check this in the task manager.

It could be, it is running as 32bit, even though the entire system is running on 64bit.

If 32bit, a third party library could be causing this. But first make sure your application is compiling for "Any CPU", as stated in the comments.

Installing Drivers for Arduino in Windows 8 / 7.

( I tried it for Uno r3, but i believe it will work for all Arduino Boards )

Plugin your Arduino Board

Go to Control Panel ---> System and Security ---> System ---> On the left pane Device Manger

Expand Other Devices.

Under Other Devices you will notice a icon with a small yellow error graphic. (Unplug all your other devices attached to any Serial Port)

Right Click on that device ---> Update Driver Software

Select Browse my computer for Driver Software

Click on Browse ---> Browse for the folder of Arduino Environment which you have downloaded from Arduino website. If not downloaded then http://arduino.cc/en/Main/Software

After Browsing mark include subfolder.

Click next ---> Your driver will be installed.

Collapse Other Devices ---> Expand Port ( its in device manager only under other devices )

You will see Arduino Written ---> Look for its COM PORT (close device manager)

Go to Arduino Environment ---> Tools ---> Serial Port ---> Select the COM PORT as mentioned in PORT in device manager. (If you are using any other Arduino Board instead of UNO then select the same in boards )

Upload your killer programmes and see them work . . .

I hope this helps. . .

The following code will give you CPU ID:

namespace required System.Management

var mbs = new ManagementObjectSearcher("Select ProcessorId From Win32_processor");
ManagementObjectCollection mbsList = mbs.Get();
string id = "";
foreach (ManagementObject mo in mbsList)
{
    id = mo["ProcessorId"].ToString();
    break;
}

For Hard disk ID and motherboard id details refer this-link

To speed up this procedure, make sure you don't use SELECT *, but only select what you really need. Use SELECT * only during development when you try to find out what you need to use, because then the query will take much longer to complete.

It is common to use the MAC address is associated with the network card.

The address is available in Java 6 through through the following API:

Java 6 Docs for Hardware Address

I haven't used it in Java, but for other network identification applications it has been helpful.

Either create an auto-increment id or a UNIQUE id and add it to the natural key you are talking about with the 4 fields. this will make every row in the table unique...

If you are using PHP 5.6 with Guzzle, Guzzle has switched to using the PHP libraries autodetect for certificates rather than it's process (ref). PHP outlines the changes here.

Finding out Where PHP/Guzzle is Looking for Certificates

You can dump where PHP is looking using the following PHP command:

 var_dump(openssl_get_cert_locations());

Getting a Certificate Bundle

For OS X testing, you can use homebrew to install openssl brew install openssl and then use openssl.cafile=/usr/local/etc/openssl/cert.pem in your php.ini or Zend Server settings (under OpenSSL).

A certificate bundle is also available from curl/Mozilla on the curl website: https://curl.haxx.se/docs/caextract.html

Telling PHP Where the Certificates Are

Once you have a bundle, either place it where PHP is already looking (which you found out above) or update openssl.cafile in php.ini. (Generally, /etc/php.ini or /etc/php/7.0/cli/php.ini or /etc/php/php.ini on Unix.)

You need to install VMware Tools on your vm:

To install VMware Tools in most VMware products:

Power on the virtual machine.

Log in to the virtual machine using an account with Administrator or root privileges.

Wait for the desktop to load and be ready.

Click Install/Upgrade VMware Tools. There are two places to find this option:

• Right-click on the running virtual machine object and choose Install/Upgrade VMware Tools.

• Right-click on the running virtual machine object and click Open Console. In the Console menu click VM and click Install/Upgrade VMware Tools.

  Note: In ESX/ESXi 4.x, navigate to VM > Guest > Install/Upgrade VMware Tools. In Workstation, navigate to VM > Install/Upgrade VMware Tools.

You can definitely use the section tag as a container. It is there to group content in a more semantically significant way than with a div or as the html5 spec says:

The section element represents a generic section of a document or application. A section, in this context, is a thematic grouping of content, typically with a heading. http://www.w3.org/TR/html5/sections.html#the-section-element

If you used ms build tools to install node the path is here:

C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\MSBuild\Microsoft\VisualStudio\NodeJs

You can use setTimeout or setInterval.

The difference is - setTimeout triggers your function only once, and then you must set it again. setInterval keeps triggering expression again and again, unless you tell it to stop

public boolean dispatchTouchEvent(MotionEvent ev){
    boolean consume =false;
    if(onInterceptTouchEvent(ev){
        consume = onTouchEvent(ev);
    }else{
        consume = child.dispatchTouchEvent(ev);
    }
}

I discovered that this behaviour only occurs after running a particular script, similar to the one in the question. I have no idea why it occurs.

It works (refreshes the graphs) if I put

plt.clf()
plt.cla()
plt.close()

after every plt.show()

This answer needs to be updated to work with Express 4.0. Here is how I got the separate http server to work:

var express = require('express');
var http = require('http');
var https = require('https');

// Primary https app
var app = express()
var port = process.env.PORT || 3000;
app.set('env', 'development');
app.set('port', port);
var router = express.Router();
app.use('/', router);
// ... other routes here
var certOpts = {
    key: '/path/to/key.pem',
    cert: '/path/to/cert.pem'
};
var server = https.createServer(certOpts, app);
server.listen(port, function(){
    console.log('Express server listening to port '+port);
});


// Secondary http app
var httpApp = express();
var httpRouter = express.Router();
httpApp.use('*', httpRouter);
httpRouter.get('*', function(req, res){
    var host = req.get('Host');
    // replace the port in the host
    host = host.replace(/:\d+$/, ":"+app.get('port'));
    // determine the redirect destination
    var destination = ['https://', host, req.url].join('');
    return res.redirect(destination);
});
var httpServer = http.createServer(httpApp);
httpServer.listen(8080);

Try gzipping some data through the gzip libary like this...

import gzip
content = "Lots of content here"
f = gzip.open('Onlyfinnaly.log.gz', 'wb')
f.write(content)
f.close()

... then run your code as posted ...

import gzip
f=gzip.open('Onlyfinnaly.log.gz','rb')
file_content=f.read()
print file_content

This method worked for me as for some reason the gzip library fails to read some files.

urllib2.urlopen handles ftp links.

Without the combined child selector you would probably do something similar to this:

foo {
  bar {
    baz {
      color: red;
    }
  }
}

If you want to reproduce the same syntax with >, you could to this:

foo {
  > bar {
    > baz {
      color: red;
    }
  }
}

This compiles to this:

foo > bar > baz {
  color: red;
}

Or in sass:

foo
  > bar
    > baz
      color: red

Someone told me once... I am going to redefine NULL to 69. Since then I don't use it :P

It makes your code quite vulnerable.

Edit:

Not everything in the standard is perfect. The macro NULL is an implementation-defined C++ null pointer constant not fully compatible with C NULL macro, what besides the type hiding implicit convert it in a useless and prone to errors tool.

NULL does not behaves as a null pointer but as a O/OL literal.

Tell me next example is not confusing:

void foo(char *); 
void foo(int); 
foo(NULL); // calls int version instead of pointer version! 

Is because of all that, in the new standard appears std::nullptr_t

If you don't want to wait for the new standard and want to use a nullptr, use at least a decent one like the proposed by Meyers (see jon.h comment).

You will need wrapper classes:

public class SomeIntInfo
{
    [XmlAttribute]
    public int Value { get; set; }
}

public class SomeStringInfo
{
    [XmlAttribute]
    public string Value { get; set; }
}

public class SomeModel
{
    [XmlElement("SomeStringElementName")]
    public SomeStringInfo SomeString { get; set; }

    [XmlElement("SomeInfoElementName")]
    public SomeIntInfo SomeInfo { get; set; }
}

or a more generic approach if you prefer:

public class SomeInfo<T>
{
    [XmlAttribute]
    public T Value { get; set; }
}

public class SomeModel
{
    [XmlElement("SomeStringElementName")]
    public SomeInfo<string> SomeString { get; set; }

    [XmlElement("SomeInfoElementName")]
    public SomeInfo<int> SomeInfo { get; set; }
}

And then:

class Program
{
    static void Main()
    {
        var model = new SomeModel
        {
            SomeString = new SomeInfo<string> { Value = "testData" },
            SomeInfo = new SomeInfo<int> { Value = 5 }
        };
        var serializer = new XmlSerializer(model.GetType());
        serializer.Serialize(Console.Out, model);
    }
}

will produce:

<?xml version="1.0" encoding="ibm850"?>
<SomeModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <SomeStringElementName Value="testData" />
  <SomeInfoElementName Value="5" />
</SomeModel>

As other answers mentioned, git config -l lists all your configuration details from your config file. Here's a partial example of that output for my configuration:

...
alias.force=push -f
alias.wd=diff --color-words
alias.shove=push -f
alias.gitignore=!git ls-files -i --exclude-from=.gitignore | xargs git rm --cached
alias.branches=!git remote show origin | grep \w*\s*(new^|tracked) -E
core.repositoryformatversion=0
core.filemode=false
core.bare=false
...

So we can grep out the alias lines, using git config -l | grep alias:

alias.force=push -f
alias.wd=diff --color-words
alias.shove=push -f
alias.gitignore=!git ls-files -i --exclude-from=.gitignore | xargs git rm --cached
alias.branches=!git remote show origin | grep \w*\s*(new^|tracked) -E

We can make this prettier by just cutting out the alias. part of each line, leaving us with this command:

git config -l | grep alias | cut -c 7-

Which prints:

force=push -f
wd=diff --color-words
shove=push -f
gitignore=!git ls-files -i --exclude-from=.gitignore | xargs git rm --cached
branches=!git remote show origin | grep \w*\s*(new^|tracked) -E

Lastly, don't forget to add this as an alias:

git config --global alias.la "!git config -l | grep alias | cut -c 7-"

Enjoy!

You may use ReadFormattedLine subroutine for all kind of formatted input. For example, the command below read a password of 8 characters, display asterisks in the screen, and continue automatically with no need to press Enter:

call :ReadFormattedLine password="********" /M "Enter password (8 chars): "

This subroutine is written in pure Batch so it does not require any additional program, and it allows several formatted input operations, like read just numbers, convert letters to uppercase, etc. You may download ReadFormattedLine subroutine from Read a line with specific format.

EDIT 2018-08-18: New method to enter an "invisible" password

The FINDSTR command have a strange bug that happen when this command is used to show characters in color AND the output of such a command is redirected to CON device. For details on how use FINDSTR command to show text in color, see this topic.

When the output of this form of FINDSTR command is redirected to CON, something strange happens after the text is output in the desired color: all the text after it is output as "invisible" characters, although a more precise description is that the text is output as black text over black background. The original text will appear if you use COLOR command to reset the foreground and background colors of the entire screen. However, when the text is "invisible" we could execute a SET /P command, so all characters entered will not appear on the screen.

@echo off
setlocal

set /P "=_" < NUL > "Enter password"
findstr /A:1E /V "^$" "Enter password" NUL > CON
del "Enter password"
set /P "password="
cls
color 07
echo The password read is: "%password%"

let JSONData = jsonString.data(using: .utf8)!

let jsonResult = try JSONSerialization.jsonObject(with: data, options: .mutableLeaves)

guard let userDictionary = jsonResult as? Dictionary<String, AnyObject> else {
            throw NSError()}

I know it's a YEARS old topic, but I got frustrated and built a role for myself to do exactly this for an arbitrary list of files. Extend as you see fit:

main.yml

- name: created destination directory
  file:
    path: /path/to/directory
    state: directory
    mode: '0750'
- include_tasks: move.yml
  loop:
    - file1
    - file2
    - file3

move.yml

- name: stat the file
  stat:
    path: {{ item }}
  register: my_file

- name: hard link the file into directory
  file:
    src: /original/path/to/{{ item }}
    dest: /path/to/directory/{{ item }}
    state: hard
  when: my_file.stat.exists

- name: Delete the original file
  file:
    path: /original/path/to/{{ item }}
    state: absent
  when: my_file.stat.exists

Note that hard linking is preferable to copying here, because it inherently preserves ownership and permissions (in addition to not consuming more disk space for a second copy of the file).

SO @NotNull just is a tag...If you want to validate it, then you must use something like hibernate validator jsr 303

ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory();
Validator validator = validatorFactory.getValidator();
 Set<ConstraintViolation<List<Searching>> violations = validator.validate(searchingList);

In sass (scss):

 button {
  color: white;
  cursor: pointer;
  border-radius: 4px;

  &:disabled{
    opacity: 0.4;

    &:hover{
      opacity: 0.4;  //this is what you want
    }
  }

  &:hover{
    opacity: 0.9;
  }
}

Hashes are indexed using the square brackets ([]). Just as arrays. But instead of indexing with the numerical index, hashes are indexed using either the string literal you used for the key, or the symbol. So if your hash is similar to

hash = { "key1" => "value1", "key2" => "value2" }

you can access the value with

hash["key1"]

or for

hash = { :key1 => "value1", :key2 => "value2"}

or the new format supported in Ruby 1.9

hash = { key1: "value1", key2: "value2" }

you can access the value with

hash[:key1]

Before importing the file, you must need to prepare the following:

• A database table to which the data from the file will be imported.
• A CSV file with data that matches with the number of columns of the table and the type of data in each column.
• The account, which connects to the MySQL database server, has FILE and INSERT privileges.

Suppose we have following table :

CREATE TABLE USING FOLLOWING QUERY :

CREATE TABLE IF NOT EXISTS `survey` (
  `projectId` bigint(20) NOT NULL,
  `surveyId` bigint(20) NOT NULL,
  `views` bigint(20) NOT NULL,
  `dateTime` datetime NOT NULL
);

YOUR CSV FILE MUST BE PROPERLY FORMATTED FOR EXAMPLE SEE FOLLOWING ATTACHED IMAGE :

If every thing is fine.. Please execute following query to LOAD DATA FROM CSV FILE :

NOTE : Please add absolute path of your CSV file

LOAD DATA INFILE '/var/www/csv/data.csv' 
INTO TABLE survey 
FIELDS TERMINATED BY ',' 
ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES;

If everything has done. you have exported data from CSV to table successfully

Very common problem in android
It can be broken down into 3 Pieces
1 ) start Activity B (Happens in Activity A)
2 ) Set requested data (Happens in activity B)
3 ) Receive requested data (Happens in activity A)

1) startActivity B

Intent i = new Intent(A.this, B.class);
startActivity(i);

2) Set requested data

In this part, you decide whether you want to send data back or not when a particular event occurs.
Eg: In activity B there is an EditText and two buttons b1, b2.
Clicking on Button b1 sends data back to activity A
Clicking on Button b2 does not send any data.

Sending data

b1......clickListener
{
   Intent resultIntent = new Intent();
   resultIntent.putExtra("Your_key","Your_value");
   setResult(RES_CODE_A,resultIntent);
   finish();
}

Not sending data

b2......clickListener
    {
       setResult(RES_CODE_B,new Intent());
       finish();
    }

user clicks back button
By default, the result is set with Activity.RESULT_CANCEL response code

3) Retrieve result

For that override onActivityResult method

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

if (resultCode == RES_CODE_A) {

     // b1 was clicked 
   String x = data.getStringExtra("RES_CODE_A");

}
else if(resultCode == RES_CODE_B){

   // b2 was clicked

}
else{
   // back button clicked 
}
}

If you are doing this in Java then why are you doing it? Just call .hashCode() on the string

Look at java.lang.BigDecimal, may solve your problem.

http://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html

The accepted answer is great, but assuming you have Node installed, you can do this much more precisely with the node library "rimraf", which allows globbing patterns. If you use this a lot (I do), just install it globally.

yarn global add rimraf

then, for instance, a pattern I use constantly:

rimraf .\**\node_modules

or for a one-liner that let's you dodge the global install, but which takes slightly longer for the the package dynamic download:

npx rimraf .\**\node_modules

One thing to check that I just found is that it won't work if there are multiple elements with the same ID. It doesn't error if you try to do this, it just fails silently

Arduino specifically provides absolutely no way to exit their loop function, as exhibited by the code that actually runs it:

setup();

for (;;) {
    loop();
    if (serialEventRun) serialEventRun();
}

Besides, on a microcontroller there isn't anything to exit to in the first place.

The closest you can do is to just halt the processor. That will stop processing until it's reset.

No need to write your own as setattr() and getattr() already exist.

The advantage of class objects probably comes into play in class definition and inheritance.

Here's a plain Javascript way of doing toggle:

<script>
  var toggle = function() {
  var mydiv = document.getElementById('newpost');
  if (mydiv.style.display === 'block' || mydiv.style.display === '')
    mydiv.style.display = 'none';
  else
    mydiv.style.display = 'block'
  }
</script>

<div id="newpost">asdf</div>
<input type="button" value="btn" onclick="toggle();">

folder = "ABC" tries to run a command named folder with arguments = and "ABC". The format of command in bash is:

command arguments separated with space

• In [ -f $newfoldername/Primetime.eyetv], [ is a command (test) and -f and $newfoldername/Primetime.eyetv] are two arguments. It expects a third argument (]) which it can't find (arguments must be separated with space) and thus will show error.
• [-f $newfoldername/Primetime.eyetv] tries to run a command [-f with argument $newfoldername/Primetime.eyetv]

In my case, it was a setting on the IIS application pool.

Select the application pool --> Advanced Settings --> Set 'Enable 32 Bit Applications' to True.

Then recycle the application pool.

Try use scale property in css3:

75% of original:

-moz-transform:scale(0.75);
-webkit-transform:scale(0.75);
transform:scale(0.75);

50% of original:

-moz-transform:scale(0.5);
-webkit-transform:scale(0.5);
transform:scale(0.5);

Here's a working example:

<div class="item item-text-wrap" ng-repeat="(key,value) in form_list">
  <b>{{key}}</b> : {{value}}

Better to use sys also-

print dir(sys._getframe())
print dir(sys._getframe().f_lineno)
print sys._getframe().f_lineno

The output is:

For storing a single row output into a variable from the select into query :

declare v_username varchare(20); SELECT username into v_username FROM users WHERE user_id = '7';

this will store the value of a single record into the variable v_username.

For storing multiple rows output into a variable from the select into query :

you have to use listagg function. listagg concatenate the resultant rows of a coloumn into a single coloumn and also to differentiate them you can use a special symbol. use the query as below SELECT listagg(username || ',' ) within group (order by username) into v_username FROM users;

With modern git you always fetch all branches (as remote-tracking branches into refs/remotes/origin/* namespace, visible with git branch -r or git remote show origin).

By default (see documentation of push.default config variable) you push matching branches, which means that first you have to do git push origin branch for git to push it always on git push.

If you want to always push all branches, you can set up push refspec. Assuming that the remote is named origin you can either use git config:

$ git config --add remote.origin.push '+refs/heads/*:refs/heads/*'
$ git config --add remote.origin.push '+refs/tags/*:refs/tags/*'

or directly edit .git/config file to have something like the following:

[remote "origin"]
        url = [email protected]:/srv/git/repo.git
        fetch = +refs/heads/*:refs/remotes/origin/*
        fetch = +refs/tags/*:refs/tags/*
        push  = +refs/heads/*:refs/heads/*
        push  = +refs/tags/*:refs/tags/*

In your main styles.css file change height/auto to whatever settings you desire. For example, 500px:

#myCarousel {
  height: auto;
  width: auto;
  overflow: hidden;
}

Whilst the accepted answer is a great solution, this is actually slightly fewer keystrokes, and scales better - based in principle on the accepted answer.

1. Move the cursor to the n in name.
2. Enter visual block mode (ctrlv).
3. Press 3j
4. Press I.
5. Type in vendor_.
6. Press esc.

Note, this has fewer keystrokes than the accepted answer provided (compare Step 3). We just count the number of j actions to perform.

If you have line numbers enabled (as illustrated above), and know the line number you wish to move to, then step 3 can be changed to #G where # is the wanted line number.

In our example above, this would be 4G. However when dealing with just a few line numbers an explicit count works well.

You can filter using index of array.

var months = ['Jan', 'March', 'April', 'June'];_x000D_
months = months.filter((month,idx) => idx < 2)_x000D_
console.log(months);

For me, the fix was to upgrade the version of System.Web.Optimization to 1.1.0.0 When I was at version 1.0.0.0 it would never resolve a .map file in a subdirectory (i.e. correctly minify and bundle scripts in a subdirectory)

I'm going to begin this answer with an illustration:

var colours = ['red', 'green', 'blue'];
document.getElementById('element').addEventListener('click', function() {
    // this is a reference to the element clicked on

    var that = this;

    colours.forEach(function() {
        // this is undefined
        // that is a reference to the element clicked on
    });
});

My answer originally demonstrated this with jQuery, which is only very slightly different:

$('#element').click(function(){
    // this is a reference to the element clicked on

    var that = this;

    $('.elements').each(function(){
        // this is a reference to the current element in the loop
        // that is still a reference to the element clicked on
    });
});

Because this frequently changes when you change the scope by calling a new function, you can't access the original value by using it. Aliasing it to that allows you still to access the original value of this.

Personally, I dislike the use of that as the alias. It is rarely obvious what it is referring to, especially if the functions are longer than a couple of lines. I always use a more descriptive alias. In my examples above, I'd probably use clickedEl.

change

});


$(document).ready(function () {
    $('.smallTabsHeader a').pluginbutton();
});

to

})(jQuery); //<-- ADD THIS


$(document).ready(function () {
    $('.smallTabsHeader a').pluginbutton();
});

This is needed because, you need to call the anonymous function that you created with

(function($){

and notice that it expects an argument that it will use internally as $, so you need to pass a reference to the jQuery object.

Additionally, you will need to change all the this. to $(this)., except the first one, in which you do return this.each

In the first one (where you do not need the $()) it is because in the plugin body, this holds a reference to the jQuery object matching your selector, but anywhere deeper than that, this refers to the specific DOM element, so you need to wrap it in $().

I solved this by right clicking in my textEdit program file and selecting [substitutions] and un-checking smart quotes.

In C and C++ all names have to be declared before they are used. If you try to use the name of a variable or a function that hasn't been declared you will get an "undeclared identifier" error.

However, functions are a special case in C (and in C only) in that you don't have to declare them first. The C compiler will the assume the function exists with the number and type of arguments as in the call. If the actual function definition does not match that you will get another error. This special case for functions does not exist in C++.

You fix these kind of errors by making sure that functions and variables are declared before they are used. In the case of printf you need to include the header file <stdio.h> (or <cstdio> in C++).

For standard functions, I recommend you check e.g. this reference site, and search for the functions you want to use. The documentation for each function tells you what header file you need.

Add .* to s in your first line.

Try:

DELETE s.* FROM spawnlist s
INNER JOIN npc n ON s.npc_templateid = n.idTemplate
WHERE (n.type = "monster");

Probably not the most efficient code, but here it goes:

$dateElements = explode('-', $dateValue);
$year = $dateElements[0];

echo $year;    //2012

switch ($dateElements[1]) {

   case '01'    :  $mo = "January";
                   break;

   case '02'    :  $mo = "February";
                   break;

   case '03'    :  $mo = "March";
                   break;

     .
     .
     .

   case '12'    :  $mo = "December";
                   break;


}

echo $mo;      //January

Markup

There are multiple solutions for this. If you want the page to be refreshed you actually don't need JavaScript, the browser can do it for you if you add this meta tag in your head tag.

<meta http-equiv="refresh" content="30">

The browser will then refresh the page every 30 seconds.

If you really want to do it with JavaScript, then you can refresh the page every 30 seconds with location.reload() (docs) inside a setTimeout():

window.setTimeout(function () {
  window.location.reload();
}, 30000);

If you don't need to refresh the whole page but only a part of it, I guess an Ajax call would be the most efficient way.

Hibernate shows this error when you attempt to persist more than one entity instance sharing the same collection reference (i.e. the collection identity in contrast with collection equality).

Note that it means the same collection, not collection element - in other words relatedPersons on both person and anotherPerson must be the same. Perhaps you're resetting that collection after entities are loaded? Or you've initialized both references with the same collection instance?

I guess there's no such feature in postman as to run concurrent tests.

If i were you i would consider Apache jMeter which is used exactly for such scenarios.

Regarding Postman, the only thing that could more or less meet your needs is - Postman Runner. There you can specify the details:

• number of iterations,
• upload csv file with data for different test runs, etc.

The runs won't be concurrent, only consecutive.

Hope that helps. But do consider jMeter (you'll love it).

What is Spring for? I will answer that question shortly, but first, let's take another look at the example by victor hugo. It's not a great example because it doesn't justify the need for a new framework.

public class BaseView {
  protected UserLister userLister;

  public BaseView() {
    userLister = new UserListerDB(); // only line of code that needs changing
  }
}

public class SomeView extends BaseView {
  public SomeView() {
    super();
  }

  public void render() {
    List<User> users = userLister.getUsers();
    view.render(users);
  }
}

Done! So now even if you have hundreds or thousands of views, you still just need to change the one line of code, as in the Spring XML approach. But changing a line of code still requires recompiling as opposed to editing XML you say? Well my fussy friend, use Ant and script away!

So what is Spring for? It's for:

1. Blind developers who follow the herd
2. Employers who do not ever want to hire graduate programmers because they don't teach such frameworks at Uni
3. Projects that started off with a bad design and need patchwork (as shown by victor hugo's example)

First - I have to direct you to http://www.angelikalanger.com/GenericsFAQ/JavaGenericsFAQ.html -- she does an amazing job.

The basic idea is that you use

<T extends SomeClass>

when the actual parameter can be SomeClass or any subtype of it.

In your example,

Map<String, Class<? extends Serializable>> expected = null;
Map<String, Class<java.util.Date>> result = null;
assertThat(result, is(expected));

You're saying that expected can contain Class objects that represent any class that implements Serializable. Your result map says it can only hold Date class objects.

When you pass in result, you're setting T to exactly Map of String to Date class objects, which doesn't match Map of String to anything that's Serializable.

One thing to check -- are you sure you want Class<Date> and not Date? A map of String to Class<Date> doesn't sound terribly useful in general (all it can hold is Date.class as values rather than instances of Date)

As for genericizing assertThat, the idea is that the method can ensure that a Matcher that fits the result type is passed in.

The one marked as correct answer, is not enough, you need one more step, type this command in the terminal in order to create the icons:

flutter pub run flutter_launcher_icons:main

If you want to just label the data points above the bar, you could use plt.annotate()

My code:

import numpy as np
import matplotlib.pyplot as plt

n = [1,2,3,4,5,]
s = [i**2 for i in n]
line = plt.bar(n,s)
plt.xlabel('Number')
plt.ylabel("Square")

for i in range(len(s)):
    plt.annotate(str(s[i]), xy=(n[i],s[i]), ha='center', va='bottom')

plt.show()

By specifying a horizontal and vertical alignment of 'center' and 'bottom' respectively one can get centered annotations.

In Microservices world (having a common shared codebase), each Microservice would have a Dockerfile whereas at the root level (generally outside of all Microservices and where your parent POM resides) you would define a docker-compose.yml to group all Microservices into a full-blown app.

In your case "Docker Compose" is preferred over "Dockerfile". Think "App" Think "Compose".

Suppose I have committed changes to master branch.I will get the commit id(xyz) of the commit now i have to go to branch for which i need to push my commits.

Single commit id xyx

git checkout branch-name
git cherry-pick xyz
git push origin branch-name

Multiple commit id's xyz abc qwe

git checkout branch-name
git cherry-pick xyz abc qwe
git push origin branch-name

You need to check your statement like this :

string url = "www.example.com/aaa/bbb.jpg";
string lenght = url.Lenght-4;
if(url.Lenght > 15)//eg 15
{
 string newString = url.Substring(18, lenght);
}

If your detached HEAD is a fast forward of master and you just want the commits upstream, you can

git push origin HEAD:master

to push directly, or

git checkout master && git merge [ref of HEAD]

will merge it back into your local master.

You need a click listener which calls addActivityItem if less than 2 options exist:

var activities = document.getElementById("activitySelector");

activities.addEventListener("click", function() {
    var options = activities.querySelectorAll("option");
    var count = options.length;
    if(typeof(count) === "undefined" || count < 2)
    {
        addActivityItem();
    }
});

activities.addEventListener("change", function() {
    if(activities.value == "addNew")
    {
        addActivityItem();
    }
});

function addActivityItem() {
    // ... Code to add item here
}

A live demo is here on JSfiddle.

In case anyone are still interested in this subject, I find that the best approach for filtering lists is to create a generic Filter class and use it with some base reflection/generics techniques contained in the Java old school SDK package. Here's what I did:

public class GenericListFilter<T> extends Filter {

    /**
     * Copycat constructor
     * @param list  the original list to be used
     */
    public GenericListFilter (List<T> list, String reflectMethodName, ArrayAdapter<T> adapter) {
        super ();

        mInternalList = new ArrayList<>(list);
        mAdapterUsed  = adapter;

        try {
            ParameterizedType stringListType = (ParameterizedType)
                    getClass().getField("mInternalList").getGenericType();
            mCompairMethod =
                    stringListType.getActualTypeArguments()[0].getClass().getMethod(reflectMethodName);
        }
        catch (Exception ex) {
            Log.w("GenericListFilter", ex.getMessage(), ex);

            try {
                if (mInternalList.size() > 0) {
                    T type = mInternalList.get(0);
                    mCompairMethod = type.getClass().getMethod(reflectMethodName);
                }
            }
            catch (Exception e) {
                Log.e("GenericListFilter", e.getMessage(), e);
            }

        }
    }

    /**
     * Let's filter the data with the given constraint
     * @param constraint
     * @return
     */
    @Override protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults results = new FilterResults();
        List<T> filteredContents = new ArrayList<>();

        if ( constraint.length() > 0 ) {
            try {
                for (T obj : mInternalList) {
                    String result = (String) mCompairMethod.invoke(obj);
                    if (result.toLowerCase().startsWith(constraint.toString().toLowerCase())) {
                        filteredContents.add(obj);
                    }
                }
            }
            catch (Exception ex) {
                Log.e("GenericListFilter", ex.getMessage(), ex);
            }
        }
        else {
            filteredContents.addAll(mInternalList);
        }

        results.values = filteredContents;
        results.count  = filteredContents.size();
        return results;
    }

    /**
     * Publish the filtering adapter list
     * @param constraint
     * @param results
     */
    @Override protected void publishResults(CharSequence constraint, FilterResults results) {
        mAdapterUsed.clear();
        mAdapterUsed.addAll((List<T>) results.values);

        if ( results.count == 0 ) {
            mAdapterUsed.notifyDataSetInvalidated();
        }
        else {
            mAdapterUsed.notifyDataSetChanged();
        }
    }

    // class properties
    private ArrayAdapter<T> mAdapterUsed;
    private List<T> mInternalList;
    private Method  mCompairMethod;
}

And afterwards, the only thing you need to do is to create the filter as a member class (possibly within the View's "onCreate") passing your adapter reference, your list, and the method to be called for filtering:

this.mFilter = new GenericFilter<MyObjectBean> (list, "getName", adapter);

The only thing missing now, is to override the "getFilter" method in the adapter class:

@Override public Filter getFilter () {
     return MyViewClass.this.mFilter;
}

All done! You should successfully filter your list - Of course, you should also implement your filter algorithm the best way that describes your need, the code bellow is just an example.. Hope it helped, take care.

.text is correct, the following code works for me:

$('#lb'+(n+1)).text(a[i].attributes[n].name+": "+ a[i].attributes[n].value);

There are two parts of this problem

1) using a parameter that would not alter an url (using params property):

$stateProvider
    .state('login', {
        params: [
            'toStateName',
            'toParamsJson'
        ],
        templateUrl: 'partials/login/Login.html'
    })

2) passing an object as parameter: Well, there is no direct way how to do it now, as every parameter is converted to string (EDIT: since 0.2.13, this is no longer true - you can use objects directly), but you can workaround it by creating the string on your own

toParamsJson = JSON.stringify(toStateParams);

and in target controller deserialize the object again

originalParams = JSON.parse($stateParams.toParamsJson);

Your web.config file should have this structure:

<configuration>
    <connectionStrings>
        <add name="MyConnectionString" connectionString="..." />
    </connectionStrings>
</configuration>

Then, to create a SQL connection using the connection string named MyConnectionString:

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString);

If you'd prefer to keep your connection strings in the AppSettings section of your configuration file, it would look like this:

<configuration>
    <appSettings>
        <add key="MyConnectionString" value="..." />
    </appSettings>
</configuration>

And then your SqlConnection constructor would look like this:

SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["MyConnectionString"]);

See http://git.or.cz/gitwiki/GitTips, section "How to compare two local repositories" in "General".

In short you are using GIT_ALTERNATE_OBJECT_DIRECTORIES environment variable to have access to object database of the other repository, and using git rev-parse with --git-dir / GIT_DIR to convert symbolic name in other repository to SHA-1 identifier.

Modern version would look something like this (assuming that you are in 'repo_a'):

GIT_ALTERNATE_OBJECT_DIRECTORIES=../repo_b/.git/objects \
   git diff $(git --git-dir=../repo_b/.git rev-parse --verify HEAD) HEAD

where ../repo_b/.git is path to object database in repo_b (it would be repo_b.git if it were bare repository). Of course you can compare arbitrary versions, not only HEADs.

Note that if repo_a and repo_b are the same repository, it might make more sense to put both of them in the same repository, either using "git remote add -f ..." to create nickname(s) for repository for repeated updates, or obe off "git fetch ..."; as described in other responses.

Ruby(1.9+)

#!/usr/bin/env ruby
Dir["*"].each do |file|
    h=Hash.new(0)
    open(file).each do |row|
        row.chomp.split("\t").each do |w|
            h[ w ] += 1
        end
    end
    h.sort{|a,b| b[1]<=>a[1] }.each{|x,y| print "#{x}:#{y}\n" }
end

Set item using data['id'] = ....

import json

with open('data.json', 'r+') as f:
    data = json.load(f)
    data['id'] = 134 # <--- add `id` value.
    f.seek(0)        # <--- should reset file position to the beginning.
    json.dump(data, f, indent=4)
    f.truncate()     # remove remaining part

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

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

and calling it from the GL update this way:

new PullTasksThread().start();

This one liner will do:

echo "$(tail -n +2 "$FILE")" > "$FILE"

It works, since tail is executed prior to echo and then the file is unlocked, hence no need for a temp file.

Use set() to remove duplicates if all values are hashable:

>>> your_list = ['one', 'two', 'one']
>>> len(your_list) != len(set(your_list))
True

A very simple answer is.

Step 1:

Firstly add your untracked files to which you want to delete:

using git add . or git add <filename>.

Step 2:

Then delete them easily using command git rm -f <filename> here rm=remove and -f=forcely.

Before doing a force deletion i would first do some checks. 1- node state: get the node name where your node is running, you can see this with the following command:

"kubectl -n YOUR_NAMESPACE describe pod YOUR_PODNAME"

Under the "Node" label you will see the node name. With that you can do:

kubectl describe node NODE_NAME

Check the "conditions" field if you see anything strange. If this is fine then you can move to the step, redo:

"kubectl -n YOUR_NAMESPACE describe pod YOUR_PODNAME"

Check the reason why it is hanging, you can find this under the "Events" section. I say this because you might need to take preliminary actions before force deleting the pod, force deleting the pod only deletes the pod itself not the underlying resource (a stuck docker container for example).

As of Spark 2.4.3

val df = SparkSession.builder().getOrCreate().emptyDataFrame

These samples run in server. So either the Windows user must have READ/WRITE permissions or must run the sample in Administrator mode.

Try running the sample in Administrator mode.

Here is a simple generic C++11 function contains which works for both arrays and containers:

using namespace std;

template<class C, typename T>
bool contains(C&& c, T e) { return find(begin(c), end(c), e) != end(c); };

Simple usage contains(arr, el) is somewhat similar to in keyword semantics in Python.

Here is a complete demo:

#include <algorithm>
#include <array>
#include <string>
#include <vector>
#include <iostream>

template<typename C, typename T>
bool contains(C&& c, T e) { 
    return std::find(std::begin(c), std::end(c), e) != std::end(c);
};

template<typename C, typename T>
void check(C&& c, T e) {
    std::cout << e << (contains(c,e) ? "" : " not") <<  " found\n";
}

int main() {
    int a[] = { 10, 15, 20 };
    std::array<int, 3> b { 10, 10, 10 };
    std::vector<int> v { 10, 20, 30 };
    std::string s { "Hello, Stack Overflow" };
    
    check(a, 10);
    check(b, 15);
    check(v, 20);
    check(s, 'Z');

    return 0;
}

Output:

10 found
15 not found
20 found
Z not found

Update for React Router 5.1+.

There is code and binaries available here for a console app that can export private keys marked as non-exportable, and it won't trigger antivirus apps like mimikatz will.

The code is based on a paper by the NCC Group. will need to run the tool with the local system account, as it works by writing directly to memory used by Windows' lsass process, in order to temporarily mark keys as exportable. This can be done using PsExec from SysInternals' PsTools:

1. Spawn a new command prompt running as the local system user:

PsExec64.exe -s -i cmd

2. In the new command prompt, run the tool:

exportrsa.exe

3. It will loop over every Local Computer store, searching for certificates with a private key. For each one, it will prompt you for a password - this is the password you want to secure the exported PFX file with, so can be whatever you want

When adding support for mimetype (as suggested by @ProVega) then it is also best practice to remove the type before adding it - this is to prevent unexpected errors when deploying to servers where support for the type already exists, for example:

<staticContent>
    <remove fileExtension=".json" />
    <mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>

substring(startIndex, endIndex(not included))

substr(startIndex, how many characters)

const string = 'JavaScript';

console.log('substring(1,2)', string.substring(1,2)); // a
console.log('substr(1,2)', string.substr(1,2)); // av

There is also difference is in plan handling.

Oracle is able form an optimized plan with concatenation of branch filters when search contains comparison of nvl result with an indexed column.

create table tt(a, b) as
select level, mod(level,10)
from dual
connect by level<=1e4;

alter table tt add constraint ix_tt_a primary key(a);
create index ix_tt_b on tt(b);

where a=nvl(:1,a)
  and b=:2;

This is not exactly showing you which rows are locked, but this may helpful to you.

You can check which statements are blocked by running this:

select cmd,* from sys.sysprocesses
where blocked > 0

It will also tell you what each block is waiting on. So you can trace that all the way up to see which statement caused the first block that caused the other blocks.

Edit to add comment from @MikeBlandford:

The blocked column indicates the spid of the blocking process. You can run kill {spid} to fix it.

You need to use this function.

JSON.parse(yourJsonString);

And it will return the object / array that was contained within the string.

You can send email using SMTP or CDO

using SMTP:

mail.From = new MailAddress("[email protected]");
mail.To.Add("to_address");
mail.Subject = "Test Mail";
mail.Body = "This is for testing SMTP mail from GMAIL";

SmtpServer.Port = 587;
SmtpServer.Credentials = new System.Net.NetworkCredential("username", "password");
SmtpServer.EnableSsl = true;

using CDO

CDO.Message oMsg = new CDO.Message();
CDO.IConfiguration iConfg;
iConfg = oMsg.Configuration;
ADODB.Fields oFields;
oFields = iConfg.Fields;
ADODB.Field oField = oFields["http://schemas.microsoft.com/cdo/configuration/sendusing"];
oFields.Update();
oMsg.Subject = "Test CDO";
oMsg.From = "from_address";
oMsg.To = "to_address";
oMsg.TextBody = "CDO Mail test";
oMsg.Send();

After the first iteration your're returning a number and then trying to get property x of it to add to the next object which is undefined and maths involving undefined results in NaN.

try returning an object contain an x property with the sum of the x properties of the parameters:

var arr = [{x:1},{x:2},{x:4}];

arr.reduce(function (a, b) {
  return {x: a.x + b.x}; // returns object with property x
})

// ES6
arr.reduce((a, b) => ({x: a.x + b.x}));

// -> {x: 7}

Explanation added from comments:

The return value of each iteration of [].reduce used as the a variable in the next iteration.

Iteration 1: a = {x:1}, b = {x:2}, {x: 3} assigned to a in Iteration 2

Iteration 2: a = {x:3}, b = {x:4}.

The problem with your example is that you're returning a number literal.

function (a, b) {
  return a.x + b.x; // returns number literal
}

Iteration 1: a = {x:1}, b = {x:2}, // returns 3 as a in next iteration

Iteration 2: a = 3, b = {x:2} returns NaN

A number literal 3 does not (typically) have a property called x so it's undefined and undefined + b.x returns NaN and NaN + <anything> is always NaN

Clarification: I prefer my method over the other top answer in this thread as I disagree with the idea that passing an optional parameter to reduce with a magic number to get out a number primitive is cleaner. It may result in fewer lines written but imo it is less readable.

In Selenium to get the URL of the active tab try,

from selenium import webdriver

driver = webdriver.Firefox()
print driver.current_url # This will print the URL of the Active link

Sending a signal to change the tab

driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + Keys.TAB)

and again use

print driver.current_url

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

You can try onload event as well;

var createIframe = function (src) {
        var self = this;
        $('<iframe>', {
            src: src,
            id: 'iframeId',
            frameborder: 1,
            scrolling: 'no',
            onload: function () {
                self.isIframeLoaded = true;
                console.log('loaded!');
            }
        }).appendTo('#iframeContainer');

    };

Try the following. It worked for me:

str = str.Split(',').Last();

It looks like IDEA solves this for you (like everything else). When loading a large project and letting it thrash, it will open a dialog to up the memory settings. Entering 2048 for Xmx and clicking "Shutdown", then restarting IDEA makes IDEA start up with more memory. This seems to work well for Mac OS, though it never seems to persist for me on Windows (not sure about IDEA 12).

I just deleted my ~/.m2/repository and that forced a re-download ;)

Do not grant all privileges over all databases to a non-root user, it is not safe (and you already have "root" with that role)

GRANT <privileges> ON database.* TO 'user'@'localhost' IDENTIFIED BY 'password';

This statement creates a new user and grants selected privileges to it. I.E.:

GRANT INSERT, SELECT, DELETE, UPDATE ON database.* TO 'user'@'localhost' IDENTIFIED BY 'password';

Take a look at the docs to see all privileges detailed

EDIT: you can look for more info with this query (log in as "root"):

select Host, User from mysql.user;

Yet another cause - I was trying to include a module in settings.gradle using

include ':MyModule'
project(':MyModule').projectDir = new File(settingsDir, '../../MyModule')

Only problem was, I had just imported the module from Eclipse an forgot to move the directory outside my application project, i.e. the path '../../MyModule' didn't exist.

multipart/form-data encoded requests are indeed not by default supported by the Servlet API prior to version 3.0. The Servlet API parses the parameters by default using application/x-www-form-urlencoded encoding. When using a different encoding, the request.getParameter() calls will all return null. When you're already on Servlet 3.0 (Glassfish 3, Tomcat 7, etc), then you can use HttpServletRequest#getParts() instead. Also see this blog for extended examples.

Prior to Servlet 3.0, a de facto standard to parse multipart/form-data requests would be using Apache Commons FileUpload. Just carefully read its User Guide and Frequently Asked Questions sections to learn how to use it. I've posted an answer with a code example before here (it also contains an example targeting Servlet 3.0).

Sample:

Label label = new Label();
label.HorizontalContentAlignment = HorizontalAlignment.Center;

Also u can consider this

which might be a little faster solution though I am not sure.

That's one of the few legitimate jobs for cat:

openssl verify -verbose -CAfile <(cat Intermediate.pem RootCert.pem) UserCert.pem

Update:

As Greg Smethells points out in the comments, this command implicitly trusts Intermediate.pem. I recommend reading the first part of the post Greg references (the second part is specifically about pyOpenSSL and not relevant to this question).

In case the post goes away I'll quote the important paragraphs:

Unfortunately, an "intermediate" cert that is actually a root / self-signed will be treated as a trusted CA when using the recommended command given above:

$ openssl verify -CAfile <(cat geotrust_global_ca.pem rogue_ca.pem) fake_sometechcompany_from_rogue_ca.com.pem fake_sometechcompany_from_rogue_ca.com.pem: OK

It seems openssl will stop verifying the chain as soon as a root certificate is encountered, which may also be Intermediate.pem if it is self-signed. In that case RootCert.pem is not considered. So make sure that Intermediate.pem is coming from a trusted source before relying on the command above.

You can use use findFragmentById in FragmentManager.

Since you are using the Support library (you are extending FragmentActivity) you can use:

getSupportFragmentManager().findFragmentById(R.id.pageview)

If you are not using the support library (so you are on Honeycomb+ and you don't want to use the support library):

getFragmentManager().findFragmentById(R.id.pageview)

Please consider that using the support library is recommended even on Honeycomb+.

When changing a picture from black to white, or white to black the hue rotate filter does not work, because black and white are not technically colors. Instead, black and white color changes (from black to white or vice-versa) must be done with the invert filter property.

I used the following steps to successfully debug over wifi connection. I recommend this solution to everybody experiencing problems using integrated solutions like Android WiFi ADB plugin. In my case it failed to keep the Wifi connection to my device after unplugging USB. The following solution overcomes this problem.

1. Connecting device

a. Connecting device using local wlan

If you have a local wlan you can connect your android device and your pc to this wlan. Then identify the IP address of the android device by looking into its wlan settings.

b. Connecting device directly using a hotspot

I prefer to connect with a hotspot on the device. This is more private and does not open your debugging connection to the (public) wlan.

1. Create a Wifi hotspot on the Android device
2. Connect PC to hotspot
3. On PC look into network connection status of this hotspot connection to find the IPADDRESS of your device.
   My system showed IPADDRESS 192.168.43.1

2. Create debugging connection

1. Connect your device to USB.
2. Issue command adb tcpip 5555 to open a port on the device for adb connection.
3. Create wireless debugging connection adb connect IPADDRESS.
   In my case the command looked like adb connect 192.168.43.1

The command adb devices -l should now display two devices if everything is ok. For example:

List of devices attached
ZY2244N2ZZ             device product:athene model:Moto_G__4_ device:athene
192.168.43.1:5555      device product:athene model:Moto_G__4_ device:athene

3. Keeping debugging connection

The tricky part comes when unplugging the USB connection. In my case both connections are closed immediately! This may not be the case for all users. For me this was the reason that I could not use Android WiFi ADB plugin for android studio. I solved the problem by manually reconnecting the Wifi after unplugging usb by

adb connect 192.168.43.1

After that adb devices -lshows a single wifi connected device. This devices shows also up in android studio and can then be selected for debugging. When the connection is unstable you may need to repeat the above command from time to time to reactivate the connection.

Use this single sql statement which is safe no need of commit/rollback with multiple statements.

           OUTPUT
                   DELETED.username,
                   DELETED.password
           WHERE username = 'X' and password = 'X'
      ) AS RowsToMove ;

There aren't a lot of "Best Practices" yet. Those of us that are using inline-styles, for React components, are still very much experimenting.

There are a number of approaches that vary wildly: React inline-style lib comparison chart

All or nothing?

What we refer to as "style" actually includes quite a few concepts:

• Layout — how an element/component looks in relationship to others
• Appearance — the characteristics of an element/component
• Behavior and state — how an element/component looks in a given state

Start with state-styles

React is already managing the state of your components, this makes styles of state and behavior a natural fit for colocation with your component logic.

Instead of building components to render with conditional state-classes, consider adding state-styles directly:

// Typical component with state-classes
<li 
 className={classnames({ 'todo-list__item': true, 'is-complete': item.complete })} />


// Using inline-styles for state
<li className='todo-list__item'
 style={(item.complete) ? styles.complete : {}} />

Note that we're using a class to style appearance but no longer using any .is- prefixed class for state and behavior.

We can use Object.assign (ES6) or _.extend (underscore/lodash) to add support for multiple states:

// Supporting multiple-states with inline-styles
<li 'todo-list__item'
 style={Object.assign({}, item.complete && styles.complete, item.due && styles.due )}>

Customization and reusability

Now that we're using Object.assign it becomes very simple to make our component reusable with different styles. If we want to override the default styles, we can do so at the call-site with props, like so: <TodoItem dueStyle={ fontWeight: "bold" } />. Implemented like this:

<li 'todo-list__item'
 style={Object.assign({},
         item.due && styles.due,
         item.due && this.props.dueStyles)}>

Layout

Personally, I don't see compelling reason to inline layout styles. There are a number of great CSS layout systems out there. I'd just use one.

That said, don't add layout styles directly to your component. Wrap your components with layout components. Here's an example.

// This couples your component to the layout system
// It reduces the reusability of your component
<UserBadge
 className="col-xs-12 col-sm-6 col-md-8"
 firstName="Michael"
 lastName="Chan" />

// This is much easier to maintain and change
<div class="col-xs-12 col-sm-6 col-md-8">
  <UserBadge
   firstName="Michael"
   lastName="Chan" />
</div>

For layout support, I often try to design components to be 100% width and height.

Appearance

This is the most contentious area of the "inline-style" debate. Ultimately, it's up to the component your designing and the comfort of your team with JavaScript.

One thing is certain, you'll need the assistance of a library. Browser-states (:hover, :focus), and media-queries are painful in raw React.

I like Radium because the syntax for those hard parts is designed to model that of SASS.

Code organization

Often you'll see a style object outside of the module. For a todo-list component, it might look something like this:

var styles = {
  root: {
    display: "block"
  },
  item: {
    color: "black"

    complete: {
      textDecoration: "line-through"
    },

    due: {
      color: "red"
    }
  },
}

getter functions

Adding a bunch of style logic to your template can get a little messy (as seen above). I like to create getter functions to compute styles:

React.createClass({
  getStyles: function () {
    return Object.assign(
      {},
      item.props.complete && styles.complete,
      item.props.due && styles.due,
      item.props.due && this.props.dueStyles
    );
  },

  render: function () {
    return <li style={this.getStyles()}>{this.props.item}</li>
  }
});

Further watching

I discussed all of these in more detail at React Europe earlier this year: Inline Styles and when it's best to 'just use CSS'.

I'm happy to help as you make new discoveries along the way :) Hit me up -> @chantastic

There are lots of free tools that can do this.

I use PDFTK (a open source cross-platform command-line tool) for things like that.

public class IntergerParser {

public static void main(String[] args){
String number = "+123123";
System.out.println(parseInt(number));
}

private static int parseInt(String number){
    char[] numChar = number.toCharArray();
    int intValue = 0;
    int decimal = 1;
    for(int index = numChar.length ; index > 0 ; index --){
        if(index == 1 ){
            if(numChar[index - 1] == '-'){
                return intValue * -1;
            } else if(numChar[index - 1] == '+'){
                return intValue;
            }
        }
        intValue = intValue + (((int)numChar[index-1] - 48) * (decimal));
        System.out.println((int)numChar[index-1] - 48+ " " + (decimal));
        decimal = decimal * 10;
    }
    return intValue;
}

Simplest solution:

$date = new DateTime('+1 day');
echo $date->format('Y-m-d H:i:s');

I'd go for:

conds = iter([a, b, c])
if any(conds) and not any(conds):
    # okay...

I think this should short-circuit fairly efficiently

Explanation

By making conds an iterator, the first use of any will short circuit and leave the iterator pointing to the next element if any item is true; otherwise, it will consume the entire list and be False. The next any takes the remaining items in the iterable, and makes sure than there aren't any other true values... If there are, the whole statement can't be true, thus there isn't one unique element (so short circuits again). The last any will either return False or will exhaust the iterable and be True.

note: the above checks if only a single condition is set

If you want to check if one or more items, but not every item is set, then you can use:

not all(conds) and any(conds)

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

For the current date activity and complete activity for previous 30 days use this, since the SYSDATE is variable in a day the previous 30th day will not have the whole data for that day.

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM mytable
WHERE create_date BETWEEN CURDATE() - INTERVAL 30 DAY AND SYSDATE()

You need to unblock the pop up windows for your browser and the code could work.

Anyone who is interested in returning anything with any statuscode with returning ResponseMessage:

//CreateResponse(HttpStatusCode, T value)
return ResponseMessage(Request.CreateResponse(HttpStatusCode.XX, object));

Truncating the table wont be possible even if you disable the foreign keys.so you can use delete command to remove all the records from the table,but be aware if you are using delete command for a table which consists of millions of records then your package will be slow and your transaction log size will increase and it may fill up your valuable disk space.

If you drop the constraints it may happen that you will fill up your table with unclean data and when you try to recreate the constraints it may not allow you to as it will give errors. so make sure that if you drop the constraints,you are loading data which are correctly related to each other and satisfy the constraint relations which you are going to recreate.

so please carefully think the pros and cons of each method and use it according to your requirements

This is an old question but Oracle's latest installers are no improvement, so I recently found myself back in this swamp, thrashing around for several days ...

My scenario was SQL Server 2016 RTM. 32-bit Oracle 12c Open Client + ODAC was eventually working fine for Visual Studio Report Designer and Integration Services designer, and also SSIS packages run through SQL Server Agent (with 32-bit option). 64-bit was working fine for Report Portal when defining and Testing an Data Source, but running the reports always gave the dreaded "ORA-12154" error.

My final solution was to switch to an EZCONNECT connection string - this avoids the TNSNAMES mess altogether. Here's a link to a detailed description, but it's basically just: host:port/sid

http://www.oracledistilled.com/oracle-database/oracle-net/using-easy-connect-ezconnect-naming-method-to-connect-to-oracle-databases/

In case it helps anyone in the future (or I get stuck on this again), here are my Oracle install steps (the full horror):

Install Oracle drivers: Oracle Client 12c (32-bit) plus ODAC.

a. Download and unzip the following files from http://www.oracle.com/technetwork/database/enterprise-edition/downloads/database12c-win64-download-2297732.html and http://www.oracle.com/technetwork/database/windows/downloads/utilsoft-087491.html ):

i. winnt_12102_client32.zip

ii. ODAC112040Xcopy_32bit.zip

b. Run winnt_12102_client32\client32\setup.exe. For the Installation Type, choose Admin. For the installation location enter C:\Oracle\Oracle12. Accept other defaults.

c. Start a Command Prompt “As Administrator” and change directory (cd) to your ODAC112040Xcopy_32bit folder.

d. Enter the command: install.bat all C:\Oracle\Oracle12 odac

e. Copy the tnsnames.ora file from another machine to these folders: *

i. C:\Oracle\Oracle12\network\admin *

ii. C:\Oracle\Oracle12\product\12.1.0\client_1\network\admin *

Install Oracle Client 12c (x64) plus ODAC

a. Download and unzip the following files from http://www.oracle.com/technetwork/database/enterprise-edition/downloads/database12c-win64-download-2297732.html and http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html ):

i. winx64_12102_client.zip

ii. ODAC121024Xcopy_x64.zip

b. Run winx64_12102_client\client\setup.exe. For the Installation Type, choose Admin. For the installation location enter C:\Oracle\Oracle12_x64. Accept other defaults.

c. Start a Command Prompt “As Administrator” and change directory (cd) to the C:\Software\Oracle Client\ODAC121024Xcopy_x64 folder.

d. Enter the command: install.bat all C:\Oracle\Oracle12_x64 odac

e. Copy the tnsnames.ora file from another machine to these folders: *

i. C:\Oracle\Oracle12_x64\network\admin *

ii. C:\Oracle\Oracle12_x64\product\12.1.0\client_1\network\admin *

* If you are going with the EZCONNECT method, then these steps are not required.

The ODAC installs are tricky and obscure - thanks to Dan English who gave me the method (detailed above) for that.

Use the CREATE SCHEMA syntax or, in SSMS, drill down through Databases -> YourDatabaseName -> Security -> Schemas. Right-click on the Schemas folder and select "New Schema..."

If your date is in the format of a string use the explode function

    array explode ( string $delimiter , string $string [, int $limit ] )
//In the case of your code

$length = strrpos($oldDate," ");
$newDate = explode( "-" , substr($oldDate,$length));
$output = $newDate[2]."/".$newDate[1]."/".$newDate[0];

Hope the above works now

Just listen to what the warning is telling you:

Reshape your data either X.reshape(-1, 1) if your data has a single feature/column and X.reshape(1, -1) if it contains a single sample.

For your example type(if you have more than one feature/column):

temp = temp.reshape(1,-1) 

For one feature/column:

temp = temp.reshape(-1,1)

ICollection<T> is used because the IEnumerable<T> interface provides no way of adding items, removing items, or otherwise modifying the collection.

Caveats: this answer only allows exports color settings.

Import shall be similar.

CMake 3.13 on Ubuntu 16.04

This approach is more flexible because it doesn't constraint MY_VARIABLE to a type:

$ cat CMakeLists.txt 
message("MY_VARIABLE=${MY_VARIABLE}")
if( MY_VARIABLE ) 
    message("MY_VARIABLE evaluates to True")
endif()

$ mkdir build && cd build

$ cmake ..
MY_VARIABLE=
-- Configuring done
-- Generating done
-- Build files have been written to: /path/to/build

$ cmake .. -DMY_VARIABLE=True
MY_VARIABLE=True
MY_VARIABLE evaluates to True
-- Configuring done
-- Generating done
-- Build files have been written to: /path/to/build

$ cmake .. -DMY_VARIABLE=False
MY_VARIABLE=False
-- Configuring done
-- Generating done
-- Build files have been written to: /path/to/build

$ cmake .. -DMY_VARIABLE=1
MY_VARIABLE=1
MY_VARIABLE evaluates to True
-- Configuring done

-- Build files have been written to: /path/to/build

$ cmake .. -DMY_VARIABLE=0
MY_VARIABLE=0
-- Configuring done
-- Generating done
-- Build files have been written to: /path/to/build

This situation calls for some preprocessor. Because if you write a function (static method) which picks the first not null value, it evaluates all items. It is problem if some items are method calls (may be time expensive method calls). And this methods are called even if any item before them is not null.

Some function like this

public static <T> T coalesce(T ...items) …

should be used but before compiling into byte code there should be a preprocessor which find usages of this „coalesce function“ and replaces it with construction like

a != null ? a : (b != null ? b : c)

Update 2014-09-02:

Thanks to Java 8 and Lambdas there is possibility to have true coalesce in Java! Including the crucial feature: particular expressions are evaluated only when needed – if earlier one is not null, then following ones are not evaluated (methods are not called, computation or disk/network operations are not done).

I wrote an article about it Java 8: coalesce – hledáme neNULLové hodnoty – (written in Czech, but I hope that code examples are understandable for everyone).

you can use unlink in the folder where you have created your symlink

You can reorder the operands:

$null -eq $foo

Note that -eq in PowerShell is not an equivalence relation.

strsplit(c('a|b','b|c'),'|',fixed=TRUE)

Things have changed since this question was posted, now with new Google Services API, you can prompt users to enable GPS:

https://developers.google.com/places/android-api/current-place

You will need to request ACCESS_FINE_LOCATION permission in your manifest:

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

This can replace the MaxLength and the MinLength

[StringLength(40, MinimumLength = 10 , ErrorMessage = "Name cannot be longer than 40 characters and less than 10")]

Use chardet https://github.com/chardet/chardet (documentation is short and easy to read).

Install python, then pip install chardet, at last use the command line command.

I tested under GB2312 and it's pretty accurate. (Make sure you have at least a few characters, sample with only 1 character may fail easily).

file is not reliable as you can see.

DefaultTableModel dm = (DefaultTableModel)table.getModel();
dm.fireTableDataChanged(); // notifies the JTable that the model has changed

Use FLOOR:

SELECT FLOOR(your_field) FROM your_table

tl;dr

• "Foo" and "bar" as metasyntactic variables were popularised by MIT and DEC, the first references are in work on LISP and PDP-1 and Project MAC from 1964 onwards.

• Many of these people were in MIT's Tech Model Railroad Club, where we find the first documented use of "foo" in tech circles in 1959 (and a variant in 1958).

• Both "foo" and "bar" (and even "baz") were well known in popular culture, especially from Smokey Stover and Pogo comics, which will have been read by many TMRC members.

• Also, it seems likely the military FUBAR contributed to their popularity.

The use of lone "foo" as a nonsense word is pretty well documented in popular culture in the early 20th century, as is the military FUBAR. (Some background reading: FOLDOC FOLDOC Jargon File Jargon File Wikipedia RFC3092)

OK, so let's find some references.

STOP PRESS! After posting this answer, I discovered this perfect article about "foo" in the Friday 14th January 1938 edition of The Tech ("MIT's oldest and largest newspaper & the first newspaper published on the web"), Volume LVII. No. 57, Price Three Cents:

On Foo-ism

The Lounger thinks that this business of Foo-ism has been carried too far by its misguided proponents, and does hereby and forthwith take his stand against its abuse. It may be that there's no foo like an old foo, and we're it, but anyway, a foo and his money are some party. (Voice from the bleachers- "Don't be foo-lish!")

As an expletive, of course, "foo!" has a definite and probably irreplaceable position in our language, although we fear that the excessive use to which it is currently subjected may well result in its falling into an early (and, alas, a dark) oblivion. We say alas because proper use of the word may result in such happy incidents as the following.

It was an 8.50 Thermodynamics lecture by Professor Slater in Room 6-120. The professor, having covered the front side of the blackboard, set the handle that operates the lift mechanism, turning meanwhile to the class to continue his discussion. The front board slowly, majestically, lifted itself, revealing the board behind it, and on that board, writ large, the symbols that spelled "FOO"!

The Tech newspaper, a year earlier, the Letter to the Editor, September 1937:

By the time the train has reached the station the neophytes are so filled with the stories of the glory of Phi Omicron Omicron, usually referred to as Foo, that they are easy prey.

...

It is not that I mind having lost my first four sons to the Grand and Universal Brotherhood of Phi Omicron Omicron, but I do wish that my fifth son, my baby, should at least be warned in advance.

Hopefully yours,

Indignant Mother of Five.

And The Tech in December 1938:

General trend of thought might be best interpreted from the remarks made at the end of the ballots. One vote said, '"I don't think what I do is any of Pulver's business," while another merely added a curt "Foo."

The first documented "foo" in tech circles is probably 1959's Dictionary of the TMRC Language:

FOO: the sacred syllable (FOO MANI PADME HUM); to be spoken only when under inspiration to commune with the Deity. Our first obligation is to keep the Foo Counters turning.

These are explained at FOLDOC. The dictionary's compiler Pete Samson said in 2005:

Use of this word at TMRC antedates my coming there. A foo counter could simply have randomly flashing lights, or could be a real counter with an obscure input.

And from 1996's Jargon File 4.0.0:

Earlier versions of this lexicon derived 'baz' as a Stanford corruption of bar. However, Pete Samson (compiler of the TMRC lexicon) reports it was already current when he joined TMRC in 1958. He says "It came from "Pogo". Albert the Alligator, when vexed or outraged, would shout 'Bazz Fazz!' or 'Rowrbazzle!' The club layout was said to model the (mythical) New England counties of Rowrfolk and Bassex (Rowrbazzle mingled with (Norfolk/Suffolk/Middlesex/Essex)."

A year before the TMRC dictionary, 1958's MIT Voo Doo Gazette ("Humor suplement of the MIT Deans' office") (PDF) mentions Foocom, in "The Laws of Murphy and Finagle" by John Banzhaf (an electrical engineering student):

Further research under a joint Foocom and Anarcom grant expanded the law to be all embracing and universally applicable: If anything can go wrong, it will!

Also 1964's MIT Voo Doo (PDF) references the TMRC usage:

Yes! I want to be an instant success and snow customers. Send me a degree in: ...

• Foo Counters

• Foo Jung

Let's find "foo", "bar" and "foobar" published in code examples.

So, Jargon File 4.4.7 says of "foobar":

Probably originally propagated through DECsystem manuals by Digital Equipment Corporation (DEC) in 1960s and early 1970s; confirmed sightings there go back to 1972.

The first published reference I can find is from February 1964, but written in June 1963, The Programming Language LISP: its Operation and Applications by Information International, Inc., with many authors, but including Timothy P. Hart and Michael Levin:

Thus, since "FOO" is a name for itself, "COMITRIN" will treat both "FOO" and "(FOO)" in exactly the same way.

Also includes other metasyntactic variables such as: FOO CROCK GLITCH / POOT TOOR / ON YOU / SNAP CRACKLE POP / X Y Z

I expect this is much the same as this next reference of "foo" from MIT's Project MAC in January 1964's AIM-064, or LISP Exercises by Timothy P. Hart and Michael Levin:

car[((FOO . CROCK) . GLITCH)]

It shares many other metasyntactic variables like: CHI / BOSTON NEW YORK / SPINACH BUTTER STEAK / FOO CROCK GLITCH / POOT TOOP / TOOT TOOT / ISTHISATRIVIALEXCERCISE / PLOOP FLOT TOP / SNAP CRACKLE POP / ONE TWO THREE / PLANE SUB THRESHER

For both "foo" and "bar" together, the earliest reference I could find is from MIT's Project MAC in June 1966's AIM-098, or PDP-6 LISP by none other than Peter Samson:

EXPLODE, like PRIN1, inserts slashes, so (EXPLODE (QUOTE FOO/ BAR)) PRIN1's as (F O O // / B A R) or PRINC's as (F O O / B A R).

Some more recallations.

@Walter Mitty recalled on this site in 2008:

I second the jargon file regarding Foo Bar. I can trace it back at least to 1963, and PDP-1 serial number 2, which was on the second floor of Building 26 at MIT. Foo and Foo Bar were used there, and after 1964 at the PDP-6 room at project MAC.

John V. Everett recalls in 1996:

When I joined DEC in 1966, foobar was already being commonly used as a throw-away file name. I believe fubar became foobar because the PDP-6 supported six character names, although I always assumed the term migrated to DEC from MIT. There were many MIT types at DEC in those days, some of whom had worked with the 7090/7094 CTSS. Since the 709x was also a 36 bit machine, foobar may have been used as a common file name there.

Foo and bar were also commonly used as file extensions. Since the text editors of the day operated on an input file and produced an output file, it was common to edit from a .foo file to a .bar file, and back again.

It was also common to use foo to fill a buffer when editing with TECO. The text string to exactly fill one disk block was IFOO$HXA127GA$$. Almost all of the PDP-6/10 programmers I worked with used this same command string.

Daniel P. B. Smith in 1998:

Dick Gruen had a device in his dorm room, the usual assemblage of B-battery, resistors, capacitors, and NE-2 neon tubes, which he called a "foo counter." This would have been circa 1964 or so.

Robert Schuldenfrei in 1996:

The use of FOO and BAR as example variable names goes back at least to 1964 and the IBM 7070. This too may be older, but that is where I first saw it. This was in Assembler. What would be the FORTRAN integer equivalent? IFOO and IBAR?

Paul M. Wexelblat in 1992:

The earliest PDP-1 Assembler used two characters for symbols (18 bit machine) programmers always left a few words as patch space to fix problems. (Jump to patch space, do new code, jump back) That space conventionally was named FU: which stood for Fxxx Up, the place where you fixed Fxxx Ups. When spoken, it was known as FU space. Later Assemblers ( e.g. MIDAS allowed three char tags so FU became FOO, and as ALL PDP-1 programmers will tell you that was FOO space.

Bruce B. Reynolds in 1996:

On the IBM side of FOO(FU)BAR is the use of the BAR side as Base Address Register; in the middle 1970's CICS programmers had to worry out the various xxxBARs...I think one of those was FRACTBAR...

Here's a straight IBM "BAR" from 1955.

I haven't been able to find any references to foo bar as "inverted foo signal" as suggested in RFC3092 and elsewhere.

Here are a some of even earlier F00s but I think they're coincidences/false positives:

• 1959 "FOO 31 IBM-704 Bettis Plant Uses a least squares technique" U.S. Atomic Energy Commission

• 1960 FOO (FO Out, F1, F2, FOO, FOI) "Digital computer and control engineering"

• 1967 FOO?

Functional way (one-liner)

xstr = lambda s: '' if s is None else s

It will return the following format like

09:56 AM

appending zero in start for the hours as well if it is less than 10

Here it is using ES6 syntax

const getTimeAMPMFormat = (date) => {
  let hours = date.getHours();
  let minutes = date.getMinutes();
  const ampm = hours >= 12 ? 'PM' : 'AM';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  hours = hours < 10 ? '0' + hours : hours;
  // appending zero in the start if hours less than 10
  minutes = minutes < 10 ? '0' + minutes : minutes;
  return hours + ':' + minutes + ' ' + ampm;
};
console.log(getTimeAMPMFormat(new Date)); // 09:59 AM

As per BashFAQ/006, you can use read with here string syntax for assigning indirect variables:

function grep_search() {
  read "$1" <<<$(ls | tail -1);
}

Usage:

$ grep_search open_box
$ echo $open_box
stack-overflow.txt

You just need to write the first query as a subquery (derived table), inside parentheses, pick an alias for it (t below) and alias the columns as well.

The DISTINCT can also be safely removed as the internal GROUP BY makes it redundant:

SELECT DATE(`date`) AS `date` , COUNT(`player_name`) AS `player_count`
FROM (
    SELECT MIN(`date`) AS `date`, `player_name`
    FROM `player_playtime`
    GROUP BY `player_name`
) AS t
GROUP BY DATE( `date`) DESC LIMIT 60 ;

Since the COUNT is now obvious that is only counting rows of the derived table, you can replace it with COUNT(*) and further simplify the query:

SELECT t.date , COUNT(*) AS player_count
FROM (
    SELECT DATE(MIN(`date`)) AS date
    FROM player_playtime
    GROUP BY player_name
) AS t
GROUP BY t.date DESC LIMIT 60 ;

I recently published a jQuery plugin which allows you to make PHP function calls in various ways: https://github.com/Xaxis/jquery.php

Simple example usage:

// Both .end() and .data() return data to variables
var strLenA = P.strlen('some string').end();
var strLenB = P.strlen('another string').end();
var totalStrLen = strLenA + strLenB;
console.log( totalStrLen ); // 25

// .data Returns data in an array
var data1 = P.crypt("Some Crypt String").data();
console.log( data1 ); // ["$1$Tk1b01rk$shTKSqDslatUSRV3WdlnI/"]

I re-factored Anand's answer to make use not only of the unique properties of a Set but also use the boolean false returned by the set.add() when an add to the set fails.

import java.util.HashSet;
import java.util.Random;
import java.util.Set;

public class randomUniqueNumberGenerator {

    public static final int SET_SIZE_REQUIRED = 10;
    public static final int NUMBER_RANGE = 100;

    public static void main(String[] args) {
        Random random = new Random();

        Set set = new HashSet<Integer>(SET_SIZE_REQUIRED);

        while(set.size()< SET_SIZE_REQUIRED) {
            while (set.add(random.nextInt(NUMBER_RANGE)) != true)
                ;
        }
        assert set.size() == SET_SIZE_REQUIRED;
        System.out.println(set);
    }
}

Use itertools.combinations(mylist, 2)

The easiest way to do this is either to use concat() to merge the arrays and then use filter() to remove the duplicates, or to use concat() and then put the merged array inside a Set().

First way:

const firstArray = [1,2, 2];
const secondArray = [3,4];
// now lets merge them
const mergedArray = firstArray.concat(secondArray); // [1,2,2,3,4]
//now use filter to remove dups
const removeDuplicates = mergedArray.filter((elem, index) =>  mergedArray.indexOf(elem) === index); // [1,2,3, 4]

Second way (but with performance implications on the UI):

const firstArray = [1,2, 2];
const secondArray = [3,4];
// now lets merge them
const mergedArray = firstArray.concat(secondArray); // [1,2,2,3,4]
const removeDuplicates = new Set(mergedArray);

Sorry for late reply. You can only use:

   nav a:hover{

                   background-color:color name !important;


                 }

It lets you define a @Section of code in your template that you can then include in other files. For example, a sidebar defined in the template, could be referenced in another included view.

//This could be used to render a @Section defined as @Section SideBar { ...
@RenderSection("SideBar", required: false);

Hope this helps.

$("body").css("background","green"); //jQuery

document.body.style.backgroundColor = "green"; //javascript

so many ways are there I think it is very easy and simple

For me the issue was signing into my Google account on the debug Chrome window. This had been working fine for me until I signed in. Once I signed out of that instance of Chrome AND choose to delete all of my settings via the checkbox, the debugger worked fine again.

My non-debugging instance of Chrome was still signed into Google and unaffected. The main issue is that my lovely plugins are gone from the debug version, but at least I can step through client code again.

This is a solutions that takes care of single and double quotes:

<?php
$php_data = array("title"=>"Example string's with \"special\" characters");

$escaped_data = json_encode( $php_data, JSON_HEX_QUOT|JSON_HEX_APOS );
$escaped_data = str_replace("\u0022", "\\\"", $escaped_data );
$escaped_data = str_replace("\u0027", "\\'",  $escaped_data );
?>
<script>
// no need to use JSON.parse()...
var js_data = <?= $escaped_data ?>;
alert(js_data.title); // should alert `Example string's with "special" characters`
</script>

One thing you can do is to stop the services on port 80 by issuing

net stop http

in a cmd. You'll be asked if you're sure you want to stop those services. I found out that I had a few services I wasn't using and disabled them.

To see who else is using port 80 type in a cmd

netstat -abno

I'm assuming you want to run Apache on port 80. If this is the case and you want to keep the conflicting services you will need to associate them to a new port.

If the problem is not a busy port you can also try the following: select "show debug information" in the XAMPP config panel. When starting Apache you'll be shown something like "Executing "c:\xampp\apache\bin\httpd.exe". If you run that

c:\xampp\apache\bin\httpd.exe

in a cmd you will get some more information (I once for instance had some issue with my httpd.conf file).

You can set a new variable and have it incremented by ++ (count up one) every time it runs, then I use a conditional statement to end it:

var intervalId = null;
var varCounter = 0;
var varName = function(){
     if(varCounter <= 10) {
          varCounter++;
          /* your code goes here */
     } else {
          clearInterval(intervalId);
     }
};

$(document).ready(function(){
     intervalId = setInterval(varName, 10000);
});

I hope that it helps and it is right.

If your xml is written by java.lang.String you can just using HttpClient in this way

    public void post() throws Exception{
        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost("http://www.baidu.com");
        String xml = "<xml>xxxx</xml>";
        HttpEntity entity = new ByteArrayEntity(xml.getBytes("UTF-8"));
        post.setEntity(entity);
        HttpResponse response = client.execute(post);
        String result = EntityUtils.toString(response.getEntity());
    }

pay attention to the Exceptions.

BTW, the example is written by the httpclient version 4.x

I guess things have changed in python 3.4. This worked for me:

print("resp:" + json.dumps(resp.json()))

In short, yes. But there are times when you might favor one vs. the other. Google "case switch vs. if else". There are some discussions already on SO too. Also, here is a good video that talks about it in the context of MATLAB:

http://blogs.mathworks.com/pick/2008/01/02/matlab-basics-switch-case-vs-if-elseif/

Personally, when I have 3 or more cases, I usually just go with case/switch.

I searched so many pages: I found a beautiful solution. Check it out:

Your code has a few things wrong with it.

• You define a JavaScript function, func_load3(), but do not call it.
• Your function is defined in the wrong place. When it is defined in your page, the HTML objects it refers to have not yet been loaded. Most JavaScript code checks whether the document is fully loaded before executing, or you can just move your code past the elements it refers to in the page.
• Your form has no means to submit it. It needs a submit button.
• You do not check whether your form has been submitted.

It is possible to set a JavaScript variable in a hidden variable in a form, then submit it, and read the value back in PHP. Here is a simple example that shows this:

<?php
if (isset($_POST['hidden1'])) {
   echo "You submitted {$_POST['hidden1']}";
   die;
}

echo <<<HTML
   <form name="myform" action="{$_SERVER['PHP_SELF']}" method="post" id="myform">
      <input type="submit" name="submit" value="Test this mess!" />
      <input type="hidden" name="hidden1" id="hidden1" />
   </form>

   <script type="text/javascript">
      document.getElementById("hidden1").value = "This is an example";
   </script>
HTML;
?>

You can easily import your model and run this:

from models import User

# User is the name of table that has a column name
users = User.query.all()

for user in users:
    print user.name

in Microsoft SQL server you can achieve this from below query:

SELECT distinct City FROM STATION WHERE City LIKE '[AEIOU]%[AEIOU]'

Or

SELECT distinct City FROM STATION WHERE City LIKE '[A,E,I,O,U]%[A,E,I,O,U]'

Update --Added Oracle Query

--Way 1 --It should work in all Oracle versions

SELECT DISTINCT CITY FROM STATION WHERE REGEXP_LIKE(LOWER(CITY), '^[aeiou]') and  REGEXP_LIKE(LOWER(CITY), '[aeiou]$');

--Way 2 --it may fail in some versions of Oracle

SELECT DISTINCT CITY FROM STATION WHERE REGEXP_LIKE(LOWER(CITY), '^[aeiou].*[aeiou]');

--Way 3 --it may fail in some versions of Oracle

SELECT DISTINCT CITY FROM STATION WHERE REGEXP_LIKE(CITY, '^[aeiou].*[aeiou]', 'i');

Short answer:

ALTER SCHEMA new_schema TRANSFER old_schema.table_name

I can confirm that the data in the table remains intact, which is probably quite important :)

Long answer as per MSDN docs,

ALTER SCHEMA schema_name 
   TRANSFER [ Object | Type | XML Schema Collection ] securable_name [;]

If it's a table (or anything besides a Type or XML Schema collection), you can leave out the word Object since that's the default.

If you want, you can still run your tests within Spring Context and set the required properties inside Spring configuration class. If you use JUnit, use SpringJUnit4ClassRunner and define dedicated configuration class for your tests like that:

The class under test:

@Component
public SomeClass {

    @Autowired
    private SomeDependency someDependency;

    @Value("${someProperty}")
    private String someProperty;
}

The test class:

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(classes = SomeClassTestsConfig.class)
public class SomeClassTests {

    @Autowired
    private SomeClass someClass;

    @Autowired
    private SomeDependency someDependency;

    @Before
    public void setup() {
       Mockito.reset(someDependency);

    @Test
    public void someTest() { ... }
}

And the configuration class for this test:

@Configuration
public class SomeClassTestsConfig {

    @Bean
    public static PropertySourcesPlaceholderConfigurer properties() throws Exception {
        final PropertySourcesPlaceholderConfigurer pspc = new PropertySourcesPlaceholderConfigurer();
        Properties properties = new Properties();

        properties.setProperty("someProperty", "testValue");

        pspc.setProperties(properties);
        return pspc;
    }
    @Bean
    public SomeClass getSomeClass() {
        return new SomeClass();
    }

    @Bean
    public SomeDependency getSomeDependency() {
        // Mockito used here for mocking dependency
        return Mockito.mock(SomeDependency.class);
    }
}

Having that said, I wouldn't recommend this approach, I just added it here for reference. In my opinion much better way is to use Mockito runner. In that case you don't run tests inside Spring at all, which is much more clear and simpler.

There's also the %n modifier which can help in certain circumstances. It returns the column on which the string was so far. Example: you want to write several rows that are within the width of the first row like a table.

int width1, width2;
int values[6][2];
printf("|%s%n|%s%n|\n", header1, &width1, header2, &width2);

for(i=0; i<6; i++)
   printf("|%*d|%*d|\n", width1, values[i][0], width2, values[i][1]);

will print two columns of the same width of whatever length the two strings header1 and header2 may have. I don't know if all implementations have the %n, but Solaris and Linux do.

Yes.

Here is some help for 2Tier and 3Tier difference, please refer below.

ANSWER:
1. 2Tier is Client server architecture and 3Tier is Client, Server and Database architecture.
2. 3Tier has a Middle stage to communicate client to server, Where as in 2Tier client directly get communication to server.
3. 3Tier is like a MVC, But having difference in topologies
4. 3Tier is linear means in that request flow is Client>>>Middle Layer(SErver application) >>>Databse server and Response is reverse.
While in 2Tier it a Triangular View >>Controller>>Model
5. 3Tier is like Website while web browser is Client application(middle layer), and ASP/PHP language code is server application.

1. Allocation always depends on your OS. If you allocate too much memory, you could end up having loaded portions into swap, which indeed is slow.
2. Whether your program runs slower or faster depends on the references the VM has to handle and to clean. The GC doesn't have to sweep through the allocated memory to find abandoned objects. It knows it's objects and the amount of memory they allocate by reference mapping. So sweeping just depends on the size of your objects. If your program behaves the same in both cases, the only performance impact should be on VM startup, when the VM tries to allocate memory provided by your OS and if you use the swap (which again leads to 1.)

@Gadde - your answer was very helpful. Thank you! I needed a "Maps"-like zoom for a div and was able to produce the feel I needed with your post. My criteria included the need to have the click repeat and continue to zoom out/in with each click. Below is my final result.

    var currentZoom = 1.0;

    $(document).ready(function () {
        $('#btn_ZoomIn').click(
            function () {
                $('#divName').animate({ 'zoom': currentZoom += .1 }, 'slow');
            })
        $('#btn_ZoomOut').click(
            function () {
                $('#divName').animate({ 'zoom': currentZoom -= .1 }, 'slow');
            })
        $('#btn_ZoomReset').click(
            function () {
                currentZoom = 1.0
                $('#divName').animate({ 'zoom': 1 }, 'slow');
            })
    });

csvreader.next() Return the next row of the reader’s iterable object as a list, parsed according to the current dialect.

BalusC's answer above works great, but there is a small fix I would add if the content of your dropdown has a smaller width than what you define in your CSS select.expand, add this to the mouseover bind:

.bind('mouseover', function() { $(this).addClass('expand').removeClass('clicked');
                                if ($(this).width() < 300) // put your desired minwidth here
                                {
                                    $(this).removeClass('expand');
                                }})

I found that in my case this is the only way working: (in my application I want to remove old log entries)

 var filterDate = dtRemoveLogs.SelectedDate.Value.Date;
 var loadOp = context.Load<ApplicationLog>(context.GetApplicationLogsQuery()
              .Where(l => l.DateTime.Year <= filterDate.Year
                       && l.DateTime.Month <= filterDate.Month
                       && l.DateTime.Day <= filterDate.Day));

I don't understand why the Jon's solution is not working ....

Nope, it is more complicated than just calling a method, if you want to transparently add it into the user's calendar.

You've got a couple of choices;

1. Calling the intent to add an event on the calendar
   This will pop up the Calendar application and let the user add the event. You can pass some parameters to prepopulate fields:

   Calendar cal = Calendar.getInstance();              
   Intent intent = new Intent(Intent.ACTION_EDIT);
   intent.setType("vnd.android.cursor.item/event");
   intent.putExtra("beginTime", cal.getTimeInMillis());
   intent.putExtra("allDay", false);
   intent.putExtra("rrule", "FREQ=DAILY");
   intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
   intent.putExtra("title", "A Test Event from android app");
   startActivity(intent);
   

   Or the more complicated one:

2. Get a reference to the calendar with this method
   (It is highly recommended not to use this method, because it could break on newer Android versions):

   private String getCalendarUriBase(Activity act) {
   
       String calendarUriBase = null;
       Uri calendars = Uri.parse("content://calendar/calendars");
       Cursor managedCursor = null;
       try {
           managedCursor = act.managedQuery(calendars, null, null, null, null);
       } catch (Exception e) {
       }
       if (managedCursor != null) {
           calendarUriBase = "content://calendar/";
       } else {
           calendars = Uri.parse("content://com.android.calendar/calendars");
           try {
               managedCursor = act.managedQuery(calendars, null, null, null, null);
           } catch (Exception e) {
           }
           if (managedCursor != null) {
               calendarUriBase = "content://com.android.calendar/";
           }
       }
       return calendarUriBase;
   }
   

   and add an event and a reminder this way:

   // get calendar
   Calendar cal = Calendar.getInstance();     
   Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
   ContentResolver cr = getContentResolver();
   
   // event insert
   ContentValues values = new ContentValues();
   values.put("calendar_id", 1);
   values.put("title", "Reminder Title");
   values.put("allDay", 0);
   values.put("dtstart", cal.getTimeInMillis() + 11*60*1000); // event starts at 11 minutes from now
   values.put("dtend", cal.getTimeInMillis()+60*60*1000); // ends 60 minutes from now
   values.put("description", "Reminder description");
   values.put("visibility", 0);
   values.put("hasAlarm", 1);
   Uri event = cr.insert(EVENTS_URI, values);
   
   // reminder insert
   Uri REMINDERS_URI = Uri.parse(getCalendarUriBase(this) + "reminders");
   values = new ContentValues();
   values.put( "event_id", Long.parseLong(event.getLastPathSegment()));
   values.put( "method", 1 );
   values.put( "minutes", 10 );
   cr.insert( REMINDERS_URI, values );
   

   You'll also need to add these permissions to your manifest for this method:

   <uses-permission android:name="android.permission.READ_CALENDAR" />
   <uses-permission android:name="android.permission.WRITE_CALENDAR" />
   

Update: ICS Issues

The above examples use the undocumented Calendar APIs, new public Calendar APIs have been released for ICS, so for this reason, to target new android versions you should use CalendarContract.

More infos about this can be found at this blog post.

write this command in your terminal :

composer update

You can now, using React hooks

Using react hooks, you can now call useState() in your function component.

useState() will return an array of 2 things:

1. A value, representing the current state.
2. Its setter. Use it to update the value.

Updating the value by its setter will force your function component to re-render,
just like forceUpdate does:

import React, { useState } from 'react';

//create your forceUpdate hook
function useForceUpdate(){
    const [value, setValue] = useState(0); // integer state
    return () => setValue(value => value + 1); // update the state to force render
}

function MyComponent() {
    // call your hook here
    const forceUpdate = useForceUpdate();
    
    return (
        <div>
            {/*Clicking on the button will force to re-render like force update does */}
            <button onClick={forceUpdate}>
                Click to re-render
            </button>
        </div>
    );
}

You can find a demo here.

The component above uses a custom hook function (useForceUpdate) which uses the react state hook useState. It increments the component's state's value and thus tells React to re-render the component.

EDIT

In an old version of this answer, the snippet used a boolean value, and toggled it in forceUpdate(). Now that I've edited my answer, the snippet use a number rather than a boolean.

Why ? (you would ask me)

Because once it happened to me that my forceUpdate() was called twice subsequently from 2 different events, and thus it was reseting the boolean value at its original state, and the component never rendered.

This is because in the useState's setter (setValue here), React compare the previous state with the new one, and render only if the state is different.

Assuming you understand the consequences of using the MEMORY engine as mentioned in comments, and here, as well as some others you'll find by searching about (no transaction safety, locking issues, etc) - you can proceed as follows:

MEMORY tables are stored differently than InnoDB, so you'll need to use an export/import strategy. First dump each table separately to a file using SELECT * FROM tablename INTO OUTFILE 'table_filename'. Create the MEMORY database and recreate the tables you'll be using with this syntax: CREATE TABLE tablename (...) ENGINE = MEMORY;. You can then import your data using LOAD DATA INFILE 'table_filename' INTO TABLE tablename for each table.

If you dont want to mess around with path variables (e.g. if you are no admin) and if you are working on windows, you can do the following which solved the problem for me.

Open graphviz.py (likely located in ...Anaconda\pkgs\graphviz***\Library\bin) in an editor. If you cant find it you might be able to open it via the error message.

Go to the fuction __find_executables and replace:

elif os.path.exists(os.path.join(path, prg + '.exe')):
   if was_quoted:
      progs[prg] = '"' + os.path.join(path, prg + '.exe') + '"'
   else:
      progs[prg] = os.path.join(path, prg + '.exe')

with

elif os.path.exists(os.path.join(path, prg + '.bat')):
   if was_quoted:
      progs[prg] = '"' + os.path.join(path, prg + '.bat') + '"'
   else:
      progs[prg] = os.path.join(path, prg + '.bat')

This one drove me crazy... basically you need two things:

1) Make sure your DNS is setup to point to your subdomain. This means to make sure you have an A Record in the DNS for your subdomain and point to the same IP.

2) You must add an additional website in IIS 7 named subdomain.example.com

• Sites > Add Website
• Site Name: subdomain.example.com
• Physical Path: select the subdomain directory
• Binding: same ip as example.com
• Host name: subdomain.example.com

python enumerate function will be satisfied your requirements

result = list(enumerate([1,3,7,12]))
print result

output

[(0, 1), (1, 3), (2, 7),(3,12)]

Two things are important for above solutions to work:

1. When applying bindings, you need to specify scope (element) !!

2. When clearing bindings, you must specify exactly same element used for scope.

Code is below

Markup

<div id="elt1" data-bind="with: data">
    <input type="text" data-bind="value: text1" >
</form>

Binding view

var myViewModel = {
  "data" : {
    "text1" : "bla bla"
  }
}:

Javascript

ko.applyBindings(myViewModel, document.getElementById('elt1'));

Clear bindings

ko.cleanNode(document.getElementById('elt1'));

The official Edit #3 answer (and variations) works well, but the thing that gets me is the 'muddying' of the business logic around the observable subscription.

Here's another approach using wrappers.

Warining: experimental code

File subscribeAndGuard.ts is used to create a new Observable extension to wrap .subscribe() and within it to wrap ngOnDestroy().
Usage is the same as .subscribe(), except for an additional first parameter referencing the component.

import { Observable } from 'rxjs/Observable';
import { Subscription } from 'rxjs/Subscription';

const subscribeAndGuard = function(component, fnData, fnError = null, fnComplete = null) {

  // Define the subscription
  const sub: Subscription = this.subscribe(fnData, fnError, fnComplete);

  // Wrap component's onDestroy
  if (!component.ngOnDestroy) {
    throw new Error('To use subscribeAndGuard, the component must implement ngOnDestroy');
  }
  const saved_OnDestroy = component.ngOnDestroy;
  component.ngOnDestroy = () => {
    console.log('subscribeAndGuard.onDestroy');
    sub.unsubscribe();
    // Note: need to put original back in place
    // otherwise 'this' is undefined in component.ngOnDestroy
    component.ngOnDestroy = saved_OnDestroy;
    component.ngOnDestroy();

  };

  return sub;
};

// Create an Observable extension
Observable.prototype.subscribeAndGuard = subscribeAndGuard;

// Ref: https://www.typescriptlang.org/docs/handbook/declaration-merging.html
declare module 'rxjs/Observable' {
  interface Observable<T> {
    subscribeAndGuard: typeof subscribeAndGuard;

Here is a component with two subscriptions, one with the wrapper and one without. The only caveat is it must implement OnDestroy (with empty body if desired), otherwise Angular does not know to call the wrapped version.

import { Component, OnInit, OnDestroy } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import 'rxjs/Rx';
import './subscribeAndGuard';

@Component({
  selector: 'app-subscribing',
  template: '<h3>Subscribing component is active</h3>',
})
export class SubscribingComponent implements OnInit, OnDestroy {

  ngOnInit() {

    // This subscription will be terminated after onDestroy
    Observable.interval(1000)
      .subscribeAndGuard(this,
        (data) => { console.log('Guarded:', data); },
        (error) => { },
        (/*completed*/) => { }
      );

    // This subscription will continue after onDestroy
    Observable.interval(1000)
      .subscribe(
        (data) => { console.log('Unguarded:', data); },
        (error) => { },
        (/*completed*/) => { }
      );
  }

  ngOnDestroy() {
    console.log('SubscribingComponent.OnDestroy');
  }
}

A demo plunker is here

An additional note: Re Edit 3 - The 'Official' Solution, this can be simplified by using takeWhile() instead of takeUntil() before subscriptions, and a simple boolean rather than another Observable in ngOnDestroy.

@Component({...})
export class SubscribingComponent implements OnInit, OnDestroy {

  iAmAlive = true;
  ngOnInit() {

    Observable.interval(1000)
      .takeWhile(() => { return this.iAmAlive; })
      .subscribe((data) => { console.log(data); });
  }

  ngOnDestroy() {
    this.iAmAlive = false;
  }
}

The size of a Java array is fixed when you allocate it, and cannot be changed.

• If you want to "grow" or "shrink" an existing array, you have to allocate a new array of the appropriate size and copy the array elements; e.g. using System.arraycopy(...) or Arrays.copyOf(...). A copy loop works as well, though it looks a bit clunky ... IMO.

• If you want to "delete" an item or items from an array (in the true sense ... not just replacing them with null), you need to allocate a new smaller array and copy across the elements you want to retain.

• Finally, you can "erase" an element in an array of a reference type by assigning null to it. But this introduces new problems:

  • If you were using null elements to mean something, you can't do this.
  • All of the code that uses the array now has to deal with the possibility of a null element in the appropriate fashion. More complexity and potential for bugs¹.

There are alternatives in the form of 3rd-party libraries (e.g. Apache Commons ArrayUtils), but you may want to consider whether it is worth adding a library dependency just for the sake of a method that you could implement yourself with 5-10 lines of code.

It is better (i.e. simpler ... and in many cases, more efficient²) to use a List class instead of an array. This will take care of (at least) growing the backing storage. And there are operations that take care of inserting and deleting elements anywhere in the list.

For instance, the ArrayList class uses an array as backing, and automatically grows the array as required. It does not automatically reduce the size of the backing array, but you can tell it to do this using the trimToSize() method; e.g.

ArrayList l = ...
l.remove(21);
l.trimToSize();  // Only do this if you really have to.

^{1 - But note that the explicit if (a[e] == null) checks themselves are likely to be "free", since they can be combined with the implicit null check that happens when you dereference the value of a[e].}

^{2 - I say it is "more efficient in many cases" because ArrayList uses a simple "double the size" strategy when it needs to grow the backing array. This means that if grow the list by repeatedly appending to it, each element will be copied on average one extra time. By contrast, if you did this with an array you would end up copying each array element close to N/2 times on average.}

I don't agree with the way that Bootstrap uses fade in (as seen in their documentation - http://v4-alpha.getbootstrap.com/components/alerts/), and my suggestion is to avoid the class names fade and in, and to avoid that pattern in general (which is currently seen in the top-rated answer to this question).

(1) The semantics are wrong - transitions are temporary, but the class names live on. So why should we name our classes fade and fade in? It should be faded and faded-in, so that when developers read the markup, it's clear that those elements were faded or faded-in. The Bootstrap team has already done away with hide for hidden, why is fade any different?

(2) Using 2 classes fade and in for a single transition pollutes the class space. And, it's not clear that fade and in are associated with one another. The in class looks like a completely independent class, like alert and alert-success.

The best solution is to use faded when the element has been faded out, and to replace that class with faded-in when the element has been faded in.

Alert Faded

So to answer the question. I think the alert markup, style, and logic should be written in the following manner. Note: Feel free to replace the jQuery logic, if you're using vanilla javascript.

HTML

<div id="saveAlert" class="alert alert-success">
  <a class="close" href="#">×</a>
  <p><strong>Well done!</strong> You successfully read this alert message.</p>
</div>

CSS

.faded {
  opacity: 0;
  transition: opacity 1s;
}

JQuery

$('#saveAlert .close').on('click', function () {

  $("#saveAlert")
    .addClass('faded');

});

1. If you want to integrate Retrofit (all steps defined here):

Goto my blog : retrofit with kotlin

2. Please use android-async-http library.

the link below explains everything step by step.

http://loopj.com/android-async-http/

Here are sample apps:

1. http://www.techrepublic.com/blog/software-engineer/calling-restful-services-from-your-android-app/

2. http://blog.strikeiron.com/bid/73189/Integrate-a-REST-API-into-Android-Application-in-less-than-15-minutes

Create a class :

public class HttpUtils {
  private static final String BASE_URL = "http://api.twitter.com/1/";
 
  private static AsyncHttpClient client = new AsyncHttpClient();

  public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.get(getAbsoluteUrl(url), params, responseHandler);
  }

  public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.post(getAbsoluteUrl(url), params, responseHandler);
  }
      
  public static void getByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.get(url, params, responseHandler);
  }

  public static void postByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.post(url, params, responseHandler);
  }

  private static String getAbsoluteUrl(String relativeUrl) {
      return BASE_URL + relativeUrl;
  }
}

Call Method :

    RequestParams rp = new RequestParams();
    rp.add("username", "aaa"); rp.add("password", "aaa@123");
                    
    HttpUtils.post(AppConstant.URL_FEED, rp, new JsonHttpResponseHandler() {
        @Override
        public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
            // If the response is JSONObject instead of expected JSONArray
            Log.d("asd", "---------------- this is response : " + response);
            try {
                JSONObject serverResp = new JSONObject(response.toString());                                                
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }                   
        }
            
        @Override
        public void onSuccess(int statusCode, Header[] headers, JSONArray timeline) {
            // Pull out the first event on the public timeline
                    
        }
    });

Please grant internet permission in your manifest file.

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

you can add compile 'com.loopj.android:android-async-http:1.4.9' for Header[] and compile 'org.json:json:20160212' for JSONObject in build.gradle file if required.

.row {
    margin-right: 15px;

throw this in your CSS

If you just need a good date-parsing function, I would look at date.js. It will take just about any date string you can throw at it, and return you a JavaScript Date object.

Once you have a Date object, you can call its getTime() method, which will give you milliseconds since January 1, 1970. Just divide that result by 1000 to get the unix timestamp value.

In code, just include date.js, then:

var unixtime = Date.parse("24-Nov-2009 17:57:35").getTime()/1000

It's an implicit conversion to bool. I.e. wherever implicit conversions are allowed, your class can be converted to bool by calling that method.

This problem arises when you have composer installed locally. To make it globally executable,run the below command in terminal

sudo mv composer.phar /usr/local/bin/composer

For CentOS 7 the command is

sudo mv composer.phar /usr/bin/composer

A clean way of deep copying objects having nested objects inside is by using lodash's cloneDeep method.

For Angular, you can do it like this:

Install lodash with yarn add lodash or npm install lodash.

In your component, import cloneDeep and use it:

import * as cloneDeep from 'lodash/cloneDeep';
...
clonedObject = cloneDeep(originalObject);

It's only 18kb added to your build, well worth for the benefits.

I've also written an article here, if you need more insight on why using lodash's cloneDeep.

This is working fine in firefox at least.

The problem I was facing is, that I got an XML object in stead of a plain text string. Reading an xml-file from my local drive works fine (same directory as the html), so I do not see why reading a text file would be an issue.

I figured that I need to tell jquery to pass a string in stead of an XML object. Which is what I did, and it finally worked:

function readFiles()
{
    $.get('file.txt', function(data) {
        alert(data);
    }, "text");
}

Note the addition of '"text"' at the end. This tells jquery to pass the contents of 'file.txt' as a string in stead of an XML object. The alert box will show the contents of the text file. If you remove the '"text"' at the end, the alert box will say 'XML object'.

A couple of observations:

• Don't create simple delegates explicitly in code like that unless you're pre-2.0 so you could use:

   BeginInvoke(new EventHandler<CoolObjectEventArgs>(mCoolObject_CoolEvent), 
               sender, 
               args);

• Also you don't need to create and populate the object array because the args parameter is a "params" type so you can just pass in the list.

• I would probably favor Invoke over BeginInvoke as the latter will result in the code being called asynchronously which may or may not be what you're after but would make handling subsequent exceptions difficult to propagate without a call to EndInvoke. What would happen is that your app will end up getting a TargetInvocationException instead.

First run

mysqld -u root --initialize-insecure 

It will create data folder with root as user without password. Then run

mysqld.exe -u root --console

The excellent JavaScript library KeyboardJS handles all types of key presses including the SHIFT key. It even allows specifying key combinations such as first pressing CTRL+x and then a.

KeyboardJS.on('shift', function() { ...handleDown... }, function() { ...handleUp... });

If you want a simple version, head to the answer by @tonycoupland):

var shiftHeld = false;
$('#control').on('mousedown', function (e) { shiftHeld = e.shiftKey });

For other circumstances in which you want the number string to be consistent, I made a function.

Someone may find this useful:

idnamer<-function(x,y){#Alphabetical designation and number of integers required
    id<-c(1:y)
    for (i in 1:length(id)){
         if(nchar(id[i])<2){
            id[i]<-paste("0",id[i],sep="")
         }
    }
    id<-paste(x,id,sep="")
    return(id)
}
idnamer("EF",28)

Sorry about the formatting.

Even same issue I faced, in browser it was showing compiled code. I have made below changes in webpack config file and it is working fine now.

 devtool: '#inline-source-map',
 debug: true,

and in loaders I kept babel-loader as first option

loaders: [
  {
    loader: "babel-loader",
    include: [path.resolve(__dirname, "src")]
  },
  { test: /\.js$/, exclude: [/app\/lib/, /node_modules/], loader: 'ng-annotate!babel' },
  { test: /\.html$/, loader: 'raw' },
  {
    test: /\.(jpe?g|png|gif|svg)$/i,
    loaders: [
      'file?hash=sha512&digest=hex&name=[hash].[ext]',
      'image-webpack?bypassOnDebug&optimizationLevel=7&interlaced=false'
    ]
  },
  {test: /\.less$/, loader: "style!css!less"},
  { test: /\.styl$/, loader: 'style!css!stylus' },
  { test: /\.css$/, loader: 'style!css' }
]
