Programs & Examples On #Isolation frameworks

The javadoc of the File class describes the class as:

An abstract representation of file and directory pathnames.

File is only a representation of a pathname, with a few methods concerning the filesystem (like exists()) and directory handling but actual streaming input and output is done elsewhere. Streams can be opened and closed, files cannot.

(My personal opinion is that it's rather unfortunate that Sun then went on to create RandomAccessFile, causing much confusion with its inconsistent naming.)

I am not sure what math can be done on a DATETIME data type, but if you are using PHP, I strongly recommend using the integer-based timestamps. Basically, you can store a 4-byte integer in the database using PHP's time() function. This makes doing math on it much more straightforward.

I did this many years back on 2003 or possibly 97, yikes!

If I recall you need to use one of the subcommands above tied to a timer. You cannot operate on the db with any connections or forms open.

So you do something about closing all forms, and kick off the timer as the last running method. (which will in turn call the compact operation once everything closes)

If you haven't figured this out I could dig through my archives and pull it up.

public class MyClass implements Cloneable {

private boolean myField= false;
// and other fields or objects

public MyClass (){}

@Override
public MyClass clone() throws CloneNotSupportedException {
   try
   {
       MyClass clonedMyClass = (MyClass)super.clone();
       // if you have custom object, then you need create a new one in here
       return clonedMyClass ;
   } catch (CloneNotSupportedException e) {
       e.printStackTrace();
       return new MyClass();
   }

  }
}

and in your code:

MyClass myClass = new MyClass();
// do some work with this object
MyClass clonedMyClass = myClass.clone();

Here is code for other way around

For Swift 3

 func amAppend(str:String) -> String{
    var temp = str
    var strArr = str.characters.split{$0 == ":"}.map(String.init)
    var hour = Int(strArr[0])!
    var min = Int(strArr[1])!
    if(hour > 12){
        temp = temp + "PM"
    }
    else{
        temp = temp + "AM"
    }
    return temp
}

I am using some nested layouts in Ruby on Rails, and in one of the layouts i have a need to read in a string from a div and set that as the title of the document.

The correct way to do this is on the server side.

In your layout, there at some point will be some code which puts the text in the div. Make this code also set some instance variable such as @page_title, and then in your outer layout have it do <%= @page_title || 'Default Title' %>

I did run into another condition with HugeClob in my Oracle database. The dbms_lob.substr only allowed a value of 4000 in the function, ex:

dbms_lob.substr(column,4000,1)

so for my HughClob which was larger, I had to use two calls in select:

select dbms_lob.substr(column,4000,1) part1, 
       dbms_lob.substr(column,4000,4001) part2 from .....

I was calling from a Java app so I simply concatenated part1 and part2 and sent as a email.

Update: The Python documentation for its regex module, re, includes a section on simulating scanf, which I found more useful than any of the answers above.

https://docs.python.org/2/library/re.html#simulating-scanf

Try

os.path.getsize(filename)

It should return the size of a file, reported by os.stat().

Drop the parentheses and commas:

 myBackupFunction ".." "..." "xx"

And the function should look like this:

function myBackupFunction() {
    # Here $1 is the first parameter, $2 the second, etc.
}

What you're looking at is an expression-bodied member not a lambda expression.

When the compiler encounters an expression-bodied property member, it essentially converts it to a getter like this:

public int MaxHealth
{
    get
    {
        return Memory[Address].IsValid ? Memory[Address].Read<int>(Offs.Life.MaxHp) : 0;
    }
}

(You can verify this for yourself by pumping the code into a tool called TryRoslyn.)

Expression-bodied members - like most C# 6 features - are just syntactic sugar. This means that they don’t provide functionality that couldn't otherwise be achieved through existing features. Instead, these new features allow a more expressive and succinct syntax to be used

As you can see, expression-bodied members have a handful of shortcuts that make property members more compact:

• There is no need to use a return statement because the compiler can infer that you want to return the result of the expression
• There is no need to create a statement block because the body is only one expression
• There is no need to use the get keyword because it is implied by the use of the expression-bodied member syntax.

I have made the final point bold because it is relevant to your actual question, which I will answer now.

The difference between...

// expression-bodied member property
public int MaxHealth => x ? y:z;

And...

// field with field initializer
public int MaxHealth = x ? y:z;

Is the same as the difference between...

public int MaxHealth
{
    get
    {
        return x ? y:z;
    }
}

And...

public int MaxHealth = x ? y:z;

Which - if you understand properties - should be obvious.

Just to be clear, though: the first listing is a property with a getter under the hood that will be called each time you access it. The second listing is is a field with a field initializer, whose expression is only evaluated once, when the type is instantiated.

This difference in syntax is actually quite subtle and can lead to a "gotcha" which is described by Bill Wagner in a post entitled "A C# 6 gotcha: Initialization vs. Expression Bodied Members".

While expression-bodied members are lambda expression-like, they are not lambda expressions. The fundamental difference is that a lambda expression results in either a delegate instance or an expression tree. Expression-bodied members are just a directive to the compiler to generate a property behind the scenes. The similarity (more or less) starts and end with the arrow (=>).

I'll also add that expression-bodied members are not limited to property members. They work on all these members:

• Properties
• Indexers
• Methods
• Operators

Added in C# 7.0

• Constructors
• Finalizers

However, they do not work on these members:

• Nested Types
• Events
• Fields

I have tried this code and It's working fine in my case.

DELETE FROM NG_USR_0_CLIENT_GRID_NEW WHERE rowid IN
( SELECT rowid FROM
  (
      SELECT wi_name, relationship, ROW_NUMBER() OVER (ORDER BY rowid DESC) RN
      FROM NG_USR_0_CLIENT_GRID_NEW
      WHERE wi_name = 'NB-0000001385-Process'
  )
  WHERE RN=2
);

For what it's worth, with iOS7 dropping support for datetime you need to use datetime-local which doesn't accept timezone portion (which makes sense).

Doesn't work (iOS anyway):

 <input type="datetime-local" value="2000-01-01T00:00:00+05:00" />

Works:

<input type="datetime-local" value="2000-01-01T00:00:00" />

PHP for value (windows safe):

strftime('%Y-%m-%dT%H:%M:%S', strtotime($my_datetime_input))

Assuming you want uppercase case letters:

function numberToLetter(num){
        var alf={
            '0': 'A', '1': 'B', '2': 'C', '3': 'D', '4': 'E', '5': 'F', '6': 'G'
        };
        if(num.length== 1) return alf[num] || ' ';
        return num.split('').map(numberToLetter);
    }

Example:

numberToLetter('023') is ["A", "C", "D"]

numberToLetter('5') is "F"

$crud->set_relation('id','students','{first_name} {last_name}');
$crud->display_as('student_id','Students Name');

I tried Dan's answer. However, the algebra used to determine the bounds means that the element must be both = the viewport size and completely inside the viewport to get true, easily leading to false negatives. If you want to determine whether an element is in the viewport at all, ryanve's answer is close, but the element being tested should overlap the viewport, so try this:

function isElementInViewport(el) {
    var rect = el.getBoundingClientRect();

    return rect.bottom > 0 &&
        rect.right > 0 &&
        rect.left < (window.innerWidth || document.documentElement.clientWidth) /* or $(window).width() */ &&
        rect.top < (window.innerHeight || document.documentElement.clientHeight) /* or $(window).height() */;
}

FWIW, the -i option was a red herring for me. ssh-copy-id will use ~/.ssh/id_rsa.pub by default.

What was keeping it from working for me was the permissions on the ~ directory, the ~/.ssh directory, and the ~/.ssh/authorized_keys file on the remote computer.

All three need to be set with chmod 755 ~ ~/.ssh ~/.ssh/authorized_keys, then ssh-copy-id your-remote-server.com will work.

input_str = "ABC"
[bin(byte) for byte in bytes(input_str, "utf-8")]

Will give:

['0b1000001', '0b1000010', '0b1000011']

if You Want to use Select All Query With Count Option, try this...

 select a.*, (Select count(b.name) from table_name as b where Condition) as totCount from table_name  as a where where Condition

If your whole JavaScript code gets processed by PHP, then you can do it just like that.

If you have individual .js files, and you don't want PHP to process them (for example, for caching reasons), then you can just pass variables around in JavaScript.

For example, in your index.php (or wherever you specify your layout), you'd do something like this:

<script type="text/javascript">
    var my_var = <?php echo json_encode($my_var); ?>;
</script>

You could then use my_var in your JavaScript files.

This method also lets you pass other than just simple integer values, as json_encode() also deals with arrays, strings, etc. correctly, serialising them into a format that JavaScript can use.

If you want to create and submit your form from Javascript as is in your question and you want to create popup window with custom features I propose this solution (I put comments above the lines i added):

var form = document.createElement("form");
form.setAttribute("method", "post");
form.setAttribute("action", "test.jsp");

// setting form target to a window named 'formresult'
form.setAttribute("target", "formresult");

var hiddenField = document.createElement("input");              
hiddenField.setAttribute("name", "id");
hiddenField.setAttribute("value", "bob");
form.appendChild(hiddenField);
document.body.appendChild(form);

// creating the 'formresult' window with custom features prior to submitting the form
window.open('test.html', 'formresult', 'scrollbars=no,menubar=no,height=600,width=800,resizable=yes,toolbar=no,status=no');

form.submit();

On your server-side code, replace the new lines (\n) with <br/>.

If you're using PHP, you can use nl2br()

If the tables are innodb you can create it like this:

CREATE TABLE accounts(
    account_id INT NOT NULL AUTO_INCREMENT,
    customer_id INT( 4 ) NOT NULL ,
    account_type ENUM( 'savings', 'credit' ) NOT NULL,
    balance FLOAT( 9 ) NOT NULL,
    PRIMARY KEY ( account_id ), 
    FOREIGN KEY (customer_id) REFERENCES customers(customer_id) 
) ENGINE=INNODB;

You have to specify that the tables are innodb because myisam engine doesn't support foreign key. Look here for more info.

im is "image process name" example /f /im notepad.exe is specified to kill image process name (program) notepad.exe

If you are using Java 6 or higher you can use wildcards of this form:

java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp

If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:

java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp

There is nothing like lib\*\* or lib\** wildcard for the kind of job you want to be done.

I stumbled upon the same need. And I read a lot on this so, here is my copper on the subject.

If you want your change detection on push, then you would have it when you change a value of an object inside right ? And you also would have it if somehow, you remove objects.

As already said, use of changeDetectionStrategy.onPush

Say you have this component you made, with changeDetectionStrategy.onPush:

<component [collection]="myCollection"></component>

Then you'd push an item and trigger the change detection :

myCollection.push(anItem);
refresh();

or you'd remove an item and trigger the change detection :

myCollection.splice(0,1);
refresh();

or you'd change an attrbibute value for an item and trigger the change detection :

myCollection[5].attribute = 'new value';
refresh();

Content of refresh :

refresh() : void {
    this.myCollection = this.myCollection.slice();
}

The slice method returns the exact same Array, and the [ = ] sign make a new reference to it, triggering the change detection every time you need it. Easy and readable :)

Regards,

This approach can be used to automate this (the following exemplary solution is in python, although obviously it can be ported to any language):

you can strip the whitespace beforehand AND save the positions of non-whitespace characters so you can use them later to find out the matched string boundary positions in the original string like the following:

def regex_search_ignore_space(regex, string):
    no_spaces = ''
    char_positions = []

    for pos, char in enumerate(string):
        if re.match(r'\S', char):  # upper \S matches non-whitespace chars
            no_spaces += char
            char_positions.append(pos)

    match = re.search(regex, no_spaces)
    if not match:
        return match

    # match.start() and match.end() are indices of start and end
    # of the found string in the spaceless string
    # (as we have searched in it).
    start = char_positions[match.start()]  # in the original string
    end = char_positions[match.end()]  # in the original string
    matched_string = string[start:end]  # see

    # the match WITH spaces is returned.
    return matched_string

with_spaces = 'a li on and a cat'
print(regex_search_ignore_space('lion', with_spaces))
# prints 'li on'

If you want to go further you can construct the match object and return it instead, so the use of this helper will be more handy.

And the performance of this function can of course also be optimized, this example is just to show the path to a solution.

Cron does not load the user's profile when running a task and you have to include the profile in your shell script explicitly.

To get the definition of the SQL codes, the easiest way is to use db2 cli!

at the unix or dos command prompt, just type

db2 "? SQL302"

this will give you the required explanation of the particular SQL code that you normally see in the java exception or your db2 sql output :)

hope this helped.

I stumbled upon this problem during attempt to dockerise Avahi which needs to be aware of its public IP to function properly. Assigning static IP to the container is tricky due to lack of support for static IP assignment in Docker.

This article describes technique how to assign static IP to the container on Debian:

1. Docker service should be started with DOCKER_OPTS="--bridge=br0 --ip-masq=false --iptables=false". I assume that br0 bridge is already configured.

2. Container should be started with --cap-add=NET_ADMIN --net=bridge

3. Inside container pre-up ip addr flush dev eth0 in /etc/network/interfaces can be used to dismiss IP address assigned by Docker as in following example:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
    pre-up ip addr flush dev eth0
    address 192.168.0.249
    netmask 255.255.255.0
    gateway 192.168.0.1

4. Container's entry script should begin with /etc/init.d/networking start. Also entry script needs to edit or populate /etc/hosts file in order to remove references to Docker-assigned IP.

Android basically works on two thread types namely UI thread and background thread. According to android documentation -

Do not access the Android UI toolkit from outside the UI thread to fix this problem, Android offers several ways to access the UI thread from other threads. Here is a list of methods that can help:

Activity.runOnUiThread(Runnable)  
View.post(Runnable)  
View.postDelayed(Runnable, long)

Now there are various methods to solve this problem. I will explain it by code sample

runOnUiThread

new Thread()
{
    public void run()
    {
        myactivity.this.runOnUiThread(new runnable()
        {
            public void run()
            {
                //Do your UI operations like dialog opening or Toast here
            }
        });
    }
}.start();

LOOPER

Class used to run a message loop for a thread. Threads by default do not have a message loop associated with them; to create one, call prepare() in the thread that is to run the loop, and then loop() to have it process messages until the loop is stopped.

class LooperThread extends Thread {
    public Handler mHandler;

    public void run() {
        Looper.prepare();

        mHandler = new Handler() {
            public void handleMessage(Message msg) {
                // process incoming messages here
            }
        };

        Looper.loop();
    }

AsyncTask

AsyncTask allows you to perform asynchronous work on your user interface. It performs the blocking operations in a worker thread and then publishes the results on the UI thread, without requiring you to handle threads and/or handlers yourself.

public void onClick(View v) {
    new CustomTask().execute((Void[])null);
}


private class CustomTask extends AsyncTask<Void, Void, Void> {

    protected Void doInBackground(Void... param) {
        //Do some work
        return null;
    }

    protected void onPostExecute(Void param) {
        //Print Toast or open dialog
    }
}

Handler

A Handler allows you to send and process Message and Runnable objects associated with a thread's MessageQueue.

Message msg = new Message();


    new Thread()
    {
        public void run()
        {
            msg.arg1=1;
            handler.sendMessage(msg);
        }
    }.start();



    Handler handler = new Handler(new Handler.Callback() {

        @Override
        public boolean handleMessage(Message msg) {
            if(msg.arg1==1)
            {
                //Print Toast or open dialog        
            }
            return false;
        }
    });

They deprecated getToken() method in the below release notes. Instead, we have to use getInstanceId.

https://firebase.google.com/docs/reference/android/com/google/firebase/iid/FirebaseInstanceId

Task<InstanceIdResult> task = FirebaseInstanceId.getInstance().getInstanceId();
task.addOnSuccessListener(new OnSuccessListener<InstanceIdResult>() {
      @Override
      public void onSuccess(InstanceIdResult authResult) {
          // Task completed successfully
          // ...
          String fcmToken = authResult.getToken();
      }
});

task.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
    // Task failed with an exception
    // ...
}
});

To handle success and failure in the same listener, attach an OnCompleteListener:

task.addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
@Override
public void onComplete(@NonNull Task<InstanceIdResult> task) {
    if (task.isSuccessful()) {
        // Task completed successfully
        InstanceIdResult authResult = task.getResult();
        String fcmToken = authResult.getToken();
    } else {
        // Task failed with an exception
        Exception exception = task.getException();
    }
}
});

Also, the FirebaseInstanceIdService Class is deprecated and they came up with onNewToken method in FireBaseMessagingService as replacement for onTokenRefresh,

you can refer to the release notes here, https://firebase.google.com/support/release-notes/android

@Override
public void onNewToken(String s) {
    super.onNewToken(s);
    Use this code logic to send the info to your server.
    //sendRegistrationToServer(s);
}

Maybe a much simpler way? Just adding to the list of answers here:

@for /f "tokens=1,* delims=: " %%a in ('sc queryex state=Inactive') do net start "%%b"

Even tried all suggestions, in my case (Office x64 - Visual Studio 2017), the only way to have both access engines on a Office 64x installation so you can use it on Visual Studio and using a 2016+ version of Office, is to install the 2010 version of the Engine.

First install the x64 from this page

https://www.microsoft.com/en-us/download/details.aspx?id=54920

and then the x86 version from this one

https://www.microsoft.com/en-us/download/details.aspx?id=13255

as from this blog: http://dinesql.blogspot.com/2017/10/microsoft-access-database-engine-2016-Redistributable-Setup-you-cannot-install-the-32-bit-version-You-cannot-install-the-64-bit-version.html

create variable count, state. initialize variables
if space is present keep count as it is else increase count. for eg:

if (string.charAt(i) == ' ' ) {
state = 0;
} else if (state == 0) {
state = 1;
count += 1;

I know this is an old question.

Here's another option - attending to different platform requirements - Source

<link rel='shortcut icon' type='image/vnd.microsoft.icon' href='/favicon.ico'> <!-- IE -->
<link rel='apple-touch-icon' type='image/png' href='/icon.57.png'> <!-- iPhone -->
<link rel='apple-touch-icon' type='image/png' sizes='72x72' href='/icon.72.png'> <!-- iPad -->
<link rel='apple-touch-icon' type='image/png' sizes='114x114' href='/icon.114.png'> <!-- iPhone4 -->
<link rel='icon' type='image/png' href='/icon.114.png'> <!-- Opera Speed Dial, at least 144×114 px -->

This is the broadest approach I have found so far.

Ultimately the decision depends on your own needs. Ask yourself, who is your target audience?

UPDATE May 27, 2018: As expected, time goes by and things change. But there's good news too. I found a tool called Real Favicon Generator that generates all the required lines for the icon to work on all modern browsers and platforms. It doesn't handle backwards compatibility though.

You need a reference to the class that contains the method you want to call. Let's say we have two classes, A and B. B has a method you want to call from A. Class A would look like this:

public class A
{
    B b; // A reference to B

    b = new B(); // Creating object of class B

    b.doSomething();  // Calling a method contained in class B from class A
}

B, which contains the doSomething() method would look like this:

public class B
{
    public void doSomething()
    {
        System.out.println("Look, I'm doing something in class B!");
    }
}

I do not have enough reputation to give a comment to Pleerock, therefor do I have to create an answer. I am sorry for that, but he put some good effort in it and I would like to answer him.

Pleerock, you created the perfect example to show why those constants should be independent from interfaces and independent from inheritance. For the client of the application is it not important that there is a technical difference between those implementation of cars. They are the same for the client, just cars. So, the client wants to look at them from that perspective, which is an interface like I_Somecar. Throughout the application will the client use only one perspective and not different ones for each different car brand.

If a client wants to compare cars prior to buying he can have a method like this:

public List<Decision> compareCars(List<I_Somecar> pCars);

An interface is a contract about behaviour and shows different objects from one perspective. The way you design it, will every car brand have its own line of inheritance. Although it is in reality quite correct, because cars can be that different that it can be like comparing completely different type of objects, in the end there is choice between different cars. And that is the perspective of the interface all brands have to share. The choice of constants should not make this impossible. Please, consider the answer of Zarkonnen.

The stopPropagation() method stops the bubbling of an event to parent elements, preventing any parent handlers from being notified of the event.

You can use the method event.isPropagationStopped() to know whether this method was ever called (on that event object).

Syntax:

Here is the simple syntax to use this method:

event.stopPropagation() 

Example:

$("div").click(function(event) {
    alert("This is : " + $(this).prop('id'));

    // Comment the following to see the difference
    event.stopPropagation();
});?

In the Hibernate mapping file for the id property, if you use any generator class, for that property you should not set the value explicitly by using a setter method.

If you set the value of the Id property explicitly, it will lead the error above. Check this to avoid this error.

I think it was not possible earlier but I recently heard about PyMob, which seems interesting because the apps are written in Python and the final outputs are native source codes in various platforms (Obj-C for iOS, Java for Android etc). This is certainly quite unique. This webpage explains it in more detail.

I haven't given it a shot yet, but will take a look soon.

Try [attr.style]="changeBackground()"

The thing that did the trick for me eventually was:

yum install gd gd-devel php-gd

and then restart apache:

service httpd restart

I've been searching high and low for an end-to-end example of a complete maven-based ear-packaged application and finally stumbled upon this. The instructions say to select option 2 when running through the CLI but for your purposes, use option 1.

You need to use regular expressions to identify the unwanted characters. For the most easily readable code, you want the str_replace_all from the stringr package, though gsub from base R works just as well.

The exact regular expression depends upon what you are trying to do. You could just remove those specific characters that you gave in the question, but it's much easier to remove all punctuation characters.

x <- "a1~!@#$%^&*(){}_+:\"<>?,./;'[]-=" #or whatever
str_replace_all(x, "[[:punct:]]", " ")

(The base R equivalent is gsub("[[:punct:]]", " ", x).)

An alternative is to swap out all non-alphanumeric characters.

str_replace_all(x, "[^[:alnum:]]", " ")

Note that the definition of what constitutes a letter or a number or a punctuatution mark varies slightly depending upon your locale, so you may need to experiment a little to get exactly what you want.

As answer by Miles, {% comment %}...{% endcomment %} is used for multi-line comments, but you can also comment out text on the same line like this:

{# some text #}

When you return b, it is just a reference to function b, but not being executed at this time.

When you return b(), you're executing the function and returning its value.

Try alerting typeof(s) in your examples. Snippet b will give you 'function'. What will snippet a give you?

You can also do it if you use the exit() function in your code. More ideally, you can do sys.exit(). sys.exit() which might terminate Python even if you are running things in parallel through the multiprocessing package.

Note: In order to use the sys.exit(), you must import it: import sys

Adjust the sequence of your environment variable %path% to make sure jre 1.7 is the default one.

This might give you an idea on how to implement it to your liking:

Calendar mCalendar = new GregorianCalendar();  
TimeZone mTimeZone = mCalendar.getTimeZone();  
int mGMTOffset = mTimeZone.getRawOffset();  
System.out.printf("GMT offset is %s hours", TimeUnit.HOURS.convert(mGMTOffset, TimeUnit.MILLISECONDS));

A simple AJAX call to your server, and then the serverside logic to get the ip address should do the trick.

$.getJSON('getip.php', function(data){
  alert('Your ip is: ' +  data.ip);
});

Then in php you might do:

<?php
/* getip.php */
header('Cache-Control: no-cache, must-revalidate');
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header('Content-type: application/json');

if (!empty($_SERVER['HTTP_CLIENT_IP']))
{
  $ip=$_SERVER['HTTP_CLIENT_IP'];
}
elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
  $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}
else
{
  $ip=$_SERVER['REMOTE_ADDR'];
}
print json_encode(array('ip' => $ip));

At a guess, AppEngine is using a 64-bit implementation of Python (-5768830964305142685 won't fit in 32 bits) and your implementation of Python is 32 bits. You can't rely on object hashes being meaningfully comparable between different implementations.

Simply use if ($web). This is true if the variable has any truthy value.

You don't need isset or empty since you know the variable exists, since you have just set it in the previous line.

Node.js (since version 0.12 - so for a while) supports execSync:

child_process.execSync(command[, options])

You can now directly do this:

const execSync = require('child_process').execSync;
code = execSync('node -v');

and it'll do what you expect. (Defaults to pipe the i/o results to the parent process). Note that you can also spawnSync now.

Use cbind e.g.

df <- data.frame(b = runif(6), c = rnorm(6))
cbind(a = 0, df)

giving:

> cbind(a = 0, df)
  a         b          c

2 0 0.5634469 -1.0777253

4 0 0.1649184 -0.4720979

I am in the same boot like you. In the case you mention, I would implement the input validation UI component as a React component.

I agree the implementation of the validation logic itself should (must) not be coupled. Therefore I would put it into a separate JS module.

That is, for logic that should not be coupled use a JS module/class in separate file, and use require/import to de-couple the component from the "service".

This allows for dependency injection and unit testing of the two independently.

Either

• HSQLDB - Used by OpenOffice, tested and stable. It's easy to use. If you want to edit your db-data, you can just open the file and edit the insert statements.

or

• H2 - Said to be faster (by the developer, who originally designed hsqldb, too)

Which one you use is up to you, depending how much performance and how much stability you need.

The developer of H2 has put up a nice performance evaluation:
http://www.h2database.com/html/performance.html

You can directly cast it:

enum MyMonthEnum { January = 1, February, March, April, May, June, July, August, September, October, November, December };

public static string GetMyMonthName(int MonthIndex)
{
  MyMonthEnum MonthName = (MyMonthEnum)MonthIndex;
  return MonthName.ToString();
}

For Example:

string MySelectedMonthName=GetMyMonthName(8);
 //then MySelectedMonthName value will be August.

I just wanted to add to this discussion that I am just compiling on VS and GCC, and used to use include guards. I have now switched to #pragma once, and the only reason for me is not performance or portability or standard as I don't really care what is standard as long as VS and GCC support it, and that is that:

#pragma once reduces possibilities for bugs.

It is all too easy to copy and paste a header file to another header file, modify it to suit ones needs, and forget to change the name of the include guard. Once both are included, it takes you a while to track down the error, as the error messages aren't necessarily clear.

Use a raw string:

>>> foo = r'baz "\"'
>>> foo
'baz "\\"'

Note that although it looks wrong, it's actually right. There is only one backslash in the string foo.

This happens because when you just type foo at the prompt, python displays the result of __repr__() on the string. This leads to the following (notice only one backslash and no quotes around the printed string):

>>> foo = r'baz "\"'
>>> foo
'baz "\\"'
>>> print(foo)
baz "\"

And let's keep going because there's more backslash tricks. If you want to have a backslash at the end of the string and use the method above you'll come across a problem:

>>> foo = r'baz \'
  File "<stdin>", line 1
    foo = r'baz \'
                 ^  
SyntaxError: EOL while scanning single-quoted string

Raw strings don't work properly when you do that. You have to use a regular string and escape your backslashes:

>>> foo = 'baz \\'
>>> print(foo)
baz \

However, if you're working with Windows file names, you're in for some pain. What you want to do is use forward slashes and the os.path.normpath() function:

myfile = os.path.normpath('c:/folder/subfolder/file.txt')
open(myfile)

This will save a lot of escaping and hair-tearing. This page was handy when going through this a while ago.

Stack overflow will only occur if you're programming in a language that doesn't have in built memory management.... Otherwise, make sure you have something in your function (or a function call, STDLbs, etc). Without recursion it would simply not be possible to have things like... Google or SQL, or any place one must efficiently sort through large data structures (classes) or databases.

Recursion is the way to go if you want to iterate through files, pretty sure that's how 'find * | ?grep *' works. Kinda dual recursion, especially with the pipe (but don't do a bunch of syscalls like so many like to do if it's anything you're going to put out there for others to use).

Higher level languages and even clang/cpp may implement it the same in the background.

I have used SVN for a long time, but whenever I used Git, I felt that Git is much powerful, lightweight, and although a little bit of learning curve involved but is better than SVN.

What I have noted is that each SVN project, as it grows, becomes a very big size project unless it is exported. Where as, GIT project (along with Git data) is very light weight in size.

In SVN, I've dealt with developers from novice to experts, and the novices and intermediates seem to introduce File conflicts if they copy one folder from another SVN project in order to re-use it. Whereas, I think in Git, you just copy the folder and it works, because Git doesn't introduce .git folders in all its subfolders (as SVN does).

After dealing alot with SVN since long time, I'm finally thinking to move my developers and me to Git, since it is easy to collaborate and merge work, as well as one great advantage is that a local copy's changes can be committed as much desired, and then finally pushed to the branch on server in one go, unlike SVN (where we have to commit the changes from time to time in the repository on server).

Anyone who can help me decide if I should really go with Git?

HTML:

<div class="foo">
    /* whatever is required */
</div>

CSS:

.foo {
    top: 0;
    transition: top ease 0.5s;
}

.foo:hover{
    top: -10px;
}

This is just a basic transition to ease the div tag up by 10px when it is hovered on. The transition property's values can be edited along with the class.hover properties to determine how the transition works.

Here's how extend/assign works: For each property in source, copy its value as-is to destination. if property values themselves are objects, there is no recursive traversal of their properties. Entire object would be taken from source and set in to destination.

Here's how merge works: For each property in source, check if that property is object itself. If it is then go down recursively and try to map child object properties from source to destination. So essentially we merge object hierarchy from source to destination. While for extend/assign, it's simple one level copy of properties from source to destination.

Here's simple JSBin that would make this crystal clear: http://jsbin.com/uXaqIMa/2/edit?js,console

Here's more elaborate version that includes array in the example as well: http://jsbin.com/uXaqIMa/1/edit?js,console

To query the nth highest bonus, say n=10, using AdventureWorks2012, Try Following code

USE AdventureWorks2012; 
GO

SELECT * FROM Sales.SalesPerson;
GO

DECLARE @grade INT;
SET @grade = 10;
SELECT MIN(Bonus)
FROM (SELECT TOP (@grade) Bonus FROM (SELECT DISTINCT(Bonus) FROM Sales.SalesPerson) AS a ORDER BY Bonus DESC) AS g

Uh, WHERE mydate<='2008-11-25' is the way to do it. That should work.

Do you get an error message? Are you using an ancient version of MySQL?

Edit: The following works fine for me on MySQL 5.x

insert into foo(d) VALUES ('2000-01-01');
insert into foo(d) VALUES ('2001-01-01');
select * from foo where d <= '2000-06-01';

Here's how I did it... No need for try-catch block... The best solution is always the simplest... Enjoy!

Because pypy is not 100% compatible, takes 8 gigs of ram to compile, is a moving target, and highly experimental, where cpython is stable, the default target for module builders for 2 decades (including c extensions that don't work on pypy), and already widely deployed.

Pypy will likely never be the reference implementation, but it is a good tool to have.

Something like this:

 $("input[name=test]").is(":checked");

Using the jQuery is() function should work.

You can also use Bootstrap 4 flex classes

We can use these classes identically for all device view.

Like: .align-item-sm-center, .align-item-md-center, .justify-content-xl-center, .justify-content-lg-center, .justify-content-xs-center

.text-center class is used to align text in center.

I am try to convert Object type variable into string using this line of code

try this to convert object value to string:

Java Code

 Object dataobject=value;
    //convert object into String  
     String convert= String.valueOf(dataobject);

If you just want to know the mean, you can use

summary(results)

It will give you more information than expected.

ex) Mininum value, 1st Qu., Median, Mean, 3rd Qu. Maxinum value, number of NAs.

Furthermore, If you want to get mean values of each column, you can simply use the method below.

mean(results$columnName, na.rm = TRUE)

That will return mean value. (you have to change 'columnName' to your variable name

Use export if you want to upload (or give to somebody) a project. If you are working with a project, use checkout.

//this is only good in .NET 4
//read your file:
List<string> ReadFile = File.ReadAllLines(@"C:\TEMP\FILE.TXT").ToList();

//manipulate data here
foreach(string line in ReadFile)
{
    //do something here
}

//write back to your file:
File.WriteAllLines(@"C:\TEMP\FILE2.TXT", ReadFile);

This function merges two dicts even if the keys in the two dictionaries are different:

def combine_dict(d1, d2):
    combined = {}
    for k in set(d1.keys()) | set(d2.keys()):
        combined[k] = tuple(d[k] for d in [d1, d2] if k in d)
    return combined

Example:

d1 = {
    'a': 1,
    'b': 2,
}
d2` = {
    'b': 'boat',
    'c': 'car',
}
combine_dict(d1, d2)
# Returns: {
#    'a': (1,),
#    'b': (2, 'boat'),
#    'c': ('car',)
# }

Slightly alternative solution to @jpp's but outputting a YearMonth string:

df['YearMonth'] = pd.to_datetime(df['Date']).apply(lambda x: '{year}-{month}'.format(year=x.year, month=x.month))

res = df.groupby('YearMonth')['Values'].sum()

In oracle an empty varchar2 and null are treated the same, and your observations show that.

when you write:

select * from table where a = '';

its the same as writing

select * from table where a = null;

and not a is null

which will never equate to true, so never return a row. same on the insert, a NOT NULL means you cant insert a null or an empty string (which is treated as a null)

This will give correct output even if there are two employees with same maximun salary

Automatic proxy detection is a process by which a Web proxy server is identified by the system and used to send requests on behalf of the client. This feature is also known as Web Proxy Auto-Discovery (WPAD). When automatic proxy detection is enabled, the system attempts to locate a proxy configuration script that is responsible for returning the set of proxies that can be used for the request.

You should put full paths in your crontab. That's the safest option.
If you don't want to do that you can put a wrapper script around your programs, and set the PATH in there.

e.g.

01 01 * * * command

becomes:

01 01 * * * /full/path/to/command

Also anything called from cron should be be very careful about the programs it runs, and probably set its own choice for the PATH variable.

EDIT:

If you don't know where the command is that you want execute which <command> from your shell and it'll tell you the path.

EDIT2:

So once your program is running, the first thing it should do is set PATH and any other required variable (e.g. LD_LIBRARY_PATH) to the values that are required for the script to run.
Basically instead of thinking how to modify the cron environment to make it more suitable for your program/script - make your script handle the environment it's given, by setting an appropriate one when it starts.

You should do it this way ideally

t = TemperatureData.objects.get(id=1)
t.value = 999
t.save(['value'])

This allow you to specify which column should be saved and rest are left as they currently are in database. (https://code.djangoproject.com/ticket/4102)!

With pandas >= 1.0 there is now a dedicated string datatype:

1) You can convert your column to this pandas string datatype using .astype('string'):

df['zipcode'] = df['zipcode'].astype('string')

2) This is different from using str which sets the pandas object datatype:

df['zipcode'] = df['zipcode'].astype(str)

3) For changing into categorical datatype use:

df['zipcode'] = df['zipcode'].astype('category')

You can see this difference in datatypes when you look at the info of the dataframe:

df = pd.DataFrame({
    'zipcode_str': [90210, 90211] ,
    'zipcode_string': [90210, 90211],
    'zipcode_category': [90210, 90211],
})

df['zipcode_str'] = df['zipcode_str'].astype(str)
df['zipcode_string'] = df['zipcode_str'].astype('string')
df['zipcode_category'] = df['zipcode_category'].astype('category')

df.info()

# you can see that the first column has dtype object
# while the second column has the new dtype string
# the third column has dtype category
 #   Column            Non-Null Count  Dtype   
---  ------            --------------  -----   
 0   zipcode_str       2 non-null      object  
 1   zipcode_string    2 non-null      string  
 2   zipcode_category  2 non-null      category
dtypes: category(1), object(1), string(1)

The 'string' extension type solves several issues with object-dtype NumPy arrays:

1. You can accidentally store a mixture of strings and non-strings in an object dtype array. A StringArray can only store strings.

2. object dtype breaks dtype-specific operations like DataFrame.select_dtypes(). There isn’t a clear way to select just text while excluding non-text, but still object-dtype columns.

3. When reading code, the contents of an object dtype array is less clear than string.
   

More info on working with the new string datatype can be found here: https://pandas.pydata.org/pandas-docs/stable/user_guide/text.html

You can't do it with pure PHP. You must do it with JavaScript. There are several articles written on how to do this.

Essentially, you can set a cookie or you can even do some Ajax to send the info to a PHP script. If you use jQuery, you can do it something like this:

jquery:

$(function() {
    $.post('some_script.php', { width: screen.width, height:screen.height }, function(json) {
        if(json.outcome == 'success') {
            // do something with the knowledge possibly?
        } else {
            alert('Unable to let PHP know what the screen resolution is!');
        }
    },'json');
});

PHP (some_script.php)

<?php
// For instance, you can do something like this:
if(isset($_POST['width']) && isset($_POST['height'])) {
    $_SESSION['screen_width'] = $_POST['width'];
    $_SESSION['screen_height'] = $_POST['height'];
    echo json_encode(array('outcome'=>'success'));
} else {
    echo json_encode(array('outcome'=>'error','error'=>"Couldn't save dimension info"));
}
?>

All that is really basic but it should get you somewhere. Normally screen resolution is not what you really want though. You may be more interested in the size of the actual browser's view port since that is actually where the page is rendered...

See the documentation of Pattern.

Assuming US-ASCII alphabet (a-z, A-Z), you could use \p{Alnum}.

A regex to check that a line contains only such characters is "^[\\p{Alnum}]*$".

That also matches empty string. To exclude empty string: "^[\\p{Alnum}]+$".

Because it's not actually a dictionary; it's another mapping type that looks like a dictionary. Use type() to verify. Pass it to dict() to get a real dictionary from it.

The Scanner class may simplify this.

        StringBuilder sb=new StringBuilder();
        Scanner scanner=null;
        try {
            scanner=new Scanner(getAssets().open("text.txt"));
            while(scanner.hasNextLine()){
                sb.append(scanner.nextLine());
                sb.append('\n');
            }
        } catch (IOException e) {
            e.printStackTrace();
        }finally {
            if(scanner!=null){try{scanner.close();}catch (Exception e){}}
        }
        mTextView.setText(sb.toString());

You need to use IBOutlet and IBAction if you are using interface builder (hence the IB prefix) for your GUI components. IBOutlet is needed to associate properties in your application with components in IB, and IBAction is used to allow your methods to be associated with actions in IB.

For example, suppose you define a button and label in IB. To dynamically change the value of the label by pushing the button, you will define an action and property in your app similar to:

UILabel IBOutlet *myLabel;
- (IBAction)pushme:(id)sender;

Then in IB you would connect myLabel with the label and connect the pushme method with the button. You need IBAction and IBOutlet for these connections to exist in IB.

The setting you are looking for is allow_url_fopen.

You have two ways of getting around it without changing php.ini, one of them is to use fsockopen(), and the other is to use cURL.

I recommend using cURL over file_get_contents() anyways, since it was built for this.

This solved my problem.

stringVar.replaceAll("\\\\n", "\\\n");

Use a document.ready() event around your call.

$(document).ready(function () {

I had to use the following steps to get there.

1) Ensure that pip and django are installed at the sudo level

• sudo apt-get install python-pip
• sudo pip install django

2) Ensure that security group in-bound rules includ http on port 80 for 0.0.0.0/0

• configured through AWS console

3) Add Public IP and DNS to ALLOWED_HOSTS

• ALLOWED_HOSTS is a list object that you can find in settings.py
• ALLOWED_HOSTS = ["75.254.65.19","ec2-54-528-27-21.compute-1.amazonaws.com"]

4) Launch development server with sudo on port 80

• sudo python manage.py runserver 0:80

• [Public DNS] i.e. ec2-54-528-27-21.compute-1.amazonaws.com
• [Public IP] i.e 75.254.65.19

Your xpath is just a little off:

count(//Property/long[text()=$parPropId])

Edit: Cerebrus quite rightly points out that the code in your OP (using the implicit value of a node) is absolutely fine for your purposes. In fact, since it's quite likely you want to work with the "Property" node rather than the "long" node, it's probably superior to ask for //Property[long=$parPropId] than the text() xpath, though you could make a case for the latter on readability grounds.

What can I say, I'm a bit tired today :)

int puts(const char *s);

puts() writes the string s and a trailing newline to stdout.

int printf(const char *format, ...);

The function printf() writes output to stdout, under the control of a format string that specifies how subsequent arguments are converted for output.

I'll use this opportunity to ask you to read the documentation.

            while(!Thread.currentThread().isInterrupted()){
                // do stuff

    t.start();

    // Sleep a second, and then interrupt
    try {

I found this worked best for me:

docker image prune --all

By default Docker will not remove named images, even if they are unused. This command will remove unused images.

Note each layer in an image is a folder inside the /usr/lib/docker/overlay2/ folder.

Quoted from this post:

The question is about how to make CTRL+SHIFT+U work in Visual Studio Code. Here is how to do it. (Version 1.8.1 or above). You can also choose a different key combination.

File-> Preferences -> Keyboard Shortcuts.

An editor will appear with keybindings.json file. Place the following JSON in there and save.

[
 {
    "key": "ctrl+shift+u",
    "command": "editor.action.transformToUppercase",
    "when": "editorTextFocus"
 },
 {
    "key": "ctrl+shift+l",
    "command": "editor.action.transformToLowercase",
    "when": "editorTextFocus"
 }
]

Now CTRL+SHIFT+U will capitalise selected text, even if multi line. In the same way, CTRL+SHIFT+L will make selected text lowercase.

These commands are built into VS Code, and no extensions are required to make them work.

You can do it the same way you do it with Mockito on real instances. For example you can chain stubs, the following line will make the first call do nothing, then second and future call to getResources will throw the exception :

// the stub of the static method
doNothing().doThrow(Exception.class).when(StaticResource.class);
StaticResource.getResource("string");

// the use of the mocked static code
StaticResource.getResource("string"); // do nothing
StaticResource.getResource("string"); // throw Exception

Thanks to a remark of Matt Lachman, note that if the default answer is not changed at mock creation time, the mock will do nothing by default. Hence writing the following code is equivalent to not writing it.

doNothing().doThrow(Exception.class).when(StaticResource.class);
StaticResource.getResource("string");

Though that being said, it can be interesting for colleagues that will read the test that you expect nothing for this particular code. Of course this can be adapted depending on how is perceived understandability of the test.

By the way, in my humble opinion you should avoid mocking static code if your crafting new code. At Mockito we think it's usually a hint to bad design, it might lead to poorly maintainable code. Though existing legacy code is yet another story.

Generally speaking if you need to mock private or static method, then this method does too much and should be externalized in an object that will be injected in the tested object.

Hope that helps.

JSONArray jsonArray = new JSONArray(yourJsonString);

for (int i = 0; i < jsonArray.length(); i++) {
     JSONObject obj1 = jsonArray.getJSONObject(i);
     JSONArray results = patient.getJSONArray("results");
     String indexForPhone =  patientProfile.getJSONObject(0).getString("indexForPhone"));
}

Change to JSONArray, then convert to JSONObject.

I had researched this and the URLRewrite method works well. Can't seem to find the change scripted anywhere well. I wrote this compatible with PowerShell v2 and above and tested it on IIS 7.5.

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.

The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.

-Xmssize Specifies the initial heap size.

-Xmxsize Specifies the maximum heap size.

-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.

Sizes are expressed in bytes. Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, g or G to indicate gigabytes.

We eventually found the answer to this.

Excel will only respect the escaping of commas and speech marks if the column value is NOT preceded by a space. So generating the file without spaces like this...

Reference,Title,Description
1,"My little title","My description, which may contain ""speech marks"" and commas."
2,"My other little title","My other description, which may also contain ""speech marks"" and commas."

... fixed the problem. Hope this helps someone!

Use the break keyword.

I had the same issue. Combining various approaches from the internet (and above) come up with the following approach (checkEmails.py)

class CheckMailer:

        def __init__(self, filename="LOG1.txt", mailbox="Mailbox - Another User Mailbox", folderindex=3):
            self.f = FileWriter(filename)
            self.outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI").Folders(mailbox)
            self.inbox = self.outlook.Folders(folderindex)


        def check(self):                
        #===============================================================================
        # for i in xrange(1,100):                           #Uncomment this section if index 3 does not work for you
        #     try:
        #         self.inbox = self.outlook.Folders(i)     # "6" refers to the index of inbox for Default User Mailbox
        #         print "%i %s" % (i,self.inbox)            # "3" refers to the index of inbox for Another user's mailbox
        #     except:
        #         print "%i does not work"%i
        #===============================================================================

                self.f.pl(time.strftime("%H:%M:%S"))
                tot = 0                
                messages = self.inbox.Items
                message = messages.GetFirst()
                while message:
                    self.f.pl (message.Subject)
                    message = messages.GetNext()
                    tot += 1
                self.f.pl("Total Messages found: %i" % tot)
                self.f.pl("-" * 80)
                self.f.flush()

if __name__ == "__main__":
    mail = CheckMailer()
    for i in xrange(320):  # this is 10.6 hours approximately
            mail.check()
            time.sleep(120.00)

For concistency I include also the code for the FileWriter class (found in FileWrapper.py). I needed this because trying to pipe UTF8 to a file in windows did not work.

class FileWriter(object):
    '''
    convenient file wrapper for writing to files
    '''


    def __init__(self, filename):
        '''
        Constructor
        '''
        self.file = open(filename, "w")

    def pl(self, a_string):
        str_uni = a_string.encode('utf-8')
        self.file.write(str_uni)
        self.file.write("\n")

    def flush(self):
        self.file.flush()

you have enlosed start_date with single quote causing it to become string, use backtick instead

If you are sure you are going to get at most a single element that passed the filter (which is guaranteed by your filter), you can use findFirst :

Optional<List> o = id1.entrySet()
                      .stream()
                      .filter( e -> e.getKey() == 1)
                      .map(Map.Entry::getValue)
                      .findFirst();

In the general case, if the filter may match multiple Lists, you can collect them to a List of Lists :

List<List> list = id1.entrySet()
                     .stream()
                     .filter(.. some predicate...)
                     .map(Map.Entry::getValue)
                     .collect(Collectors.toList());

http://www.cplusplus.com/reference/std/iterator/ has a handy chart that details the specs of § 24.2.2 of the C++11 standard. Basically, the iterators have tags that describe the valid operations, and the tags have a hierarchy. Below is purely symbolic, these classes don't actually exist as such.

iterator {
    iterator(const iterator&);
    ~iterator();
    iterator& operator=(const iterator&);
    iterator& operator++(); //prefix increment
    reference operator*() const;
    friend void swap(iterator& lhs, iterator& rhs); //C++11 I think
};

input_iterator : public virtual iterator {
    iterator operator++(int); //postfix increment
    value_type operator*() const;
    pointer operator->() const;
    friend bool operator==(const iterator&, const iterator&);
    friend bool operator!=(const iterator&, const iterator&); 
};
//once an input iterator has been dereferenced, it is 
//undefined to dereference one before that.

output_iterator : public virtual iterator {
    reference operator*() const;
    iterator operator++(int); //postfix increment
};
//dereferences may only be on the left side of an assignment
//once an output iterator has been dereferenced, it is 
//undefined to dereference one before that.

forward_iterator : input_iterator, output_iterator {
    forward_iterator();
};
//multiple passes allowed

bidirectional_iterator : forward_iterator {
    iterator& operator--(); //prefix decrement
    iterator operator--(int); //postfix decrement
};

random_access_iterator : bidirectional_iterator {
    friend bool operator<(const iterator&, const iterator&);
    friend bool operator>(const iterator&, const iterator&);
    friend bool operator<=(const iterator&, const iterator&);
    friend bool operator>=(const iterator&, const iterator&);

    iterator& operator+=(size_type);
    friend iterator operator+(const iterator&, size_type);
    friend iterator operator+(size_type, const iterator&);
    iterator& operator-=(size_type);  
    friend iterator operator-(const iterator&, size_type);
    friend difference_type operator-(iterator, iterator);

    reference operator[](size_type) const;
};

contiguous_iterator : random_access_iterator { //C++17
}; //elements are stored contiguously in memory.

You can either specialize std::iterator_traits<youriterator>, or put the same typedefs in the iterator itself, or inherit from std::iterator (which has these typedefs). I prefer the second option, to avoid changing things in the std namespace, and for readability, but most people inherit from std::iterator.

struct std::iterator_traits<youriterator> {        
    typedef ???? difference_type; //almost always ptrdiff_t
    typedef ???? value_type; //almost always T
    typedef ???? reference; //almost always T& or const T&
    typedef ???? pointer; //almost always T* or const T*
    typedef ???? iterator_category;  //usually std::forward_iterator_tag or similar
};

Note the iterator_category should be one of std::input_iterator_tag, std::output_iterator_tag, std::forward_iterator_tag, std::bidirectional_iterator_tag, or std::random_access_iterator_tag, depending on which requirements your iterator satisfies. Depending on your iterator, you may choose to specialize std::next, std::prev, std::advance, and std::distance as well, but this is rarely needed. In extremely rare cases you may wish to specialize std::begin and std::end.

Your container should probably also have a const_iterator, which is a (possibly mutable) iterator to constant data that is similar to your iterator except it should be implicitly constructable from a iterator and users should be unable to modify the data. It is common for its internal pointer to be a pointer to non-constant data, and have iterator inherit from const_iterator so as to minimize code duplication.

My post at Writing your own STL Container has a more complete container/iterator prototype.

Is contextmenu an event?

I would use onmousedown or onclick then grab the MouseEvent's button property to determine which button was pressed (0 = left, 1 = middle, 2 = right).

The easiest way to solve this problem in Angular is to do:

In Template:

<select [ngModel]="selectedObjectIndex">
  <option [value]="i" *ngFor="let object of objects; let i = index;">{{object.name}}</option>
</select>

In your class:

this.selectedObjectIndex = 1/0/your number wich item should be selected

Using .getActivity() solves this issue:

For eg.

Intent i= new Intent(MainActivity.this.getActivity(), Next.class);
startActivity(i);

Hope this helps.

Cheers.

What you are trying to do is very dangerous. Think about this carefully. There is a very good reason for the default behaviour of auto increment.

Consider this:

A record is deleted in one table that has a relationship with another table. The corresponding record in the second table cannot be deleted for auditing reasons. This record becomes orphaned from the first table. If a new record is inserted into the first table, and a sequential primary key is used, this record is now linked to the orphan. Obviously, this is bad. By using an auto incremented PK, an id that has never been used before is always guaranteed. This means that orphans remain orphans, which is correct.

Thanks Burhan Khalid. Your advice to make a a soft link make my installation finally work.

To recap:

1. You need both the basic version and the SDK version of instant client

2. You need to set both LD_LIBRARY_PATH and ORACLE_HOME

3. You need to create a soft link (ln -s libclntsh.so.12.1 libclntsh.so in my case)

None of this is documented anywhere, which is quite unbelievable and quite frustrating. I spent over 3 hours yesterday with failed builds because I didn't know to create a soft link.

With template literals, you can use multiple spaces or multi-line strings and string interpolation. Template Literals are a new ES2015 / ES6 feature that allows you to work with strings. The syntax is very simple, just use backticks instead of single or double quotes:

let a = `something                 something`;

and to make multiline strings just press enter to create a new line, with no special characters:

let a = `something 

    
                         something`;

The results are exactly the same as you write in the string.

Here's how to force the target inside a click handler:

$('a#link_id').click(function() {
    $(this).attr('target', '_blank');
});

Task.WaitAll blocks the current thread until everything has completed.

Task.WhenAll returns a task which represents the action of waiting until everything has completed.

That means that from an async method, you can use:

await Task.WhenAll(tasks);

... which means your method will continue when everything's completed, but you won't tie up a thread to just hang around until that time.

I disagree that .form-group should be within .col-*-n elements. In my experience, all the appropriate padding happens automatically when you use .form-group like .row within a form.

<div class="form-group">
    <div class="col-sm-12">
        <label for="user_login">Username</label>
        <input class="form-control" id="user_login" name="user[login]" required="true" size="30" type="text" />
    </div>
</div>

Check out this demo.

Altering the demo slightly by adding .form-horizontal to the form tag changes some of that padding.

<form action="#" method="post" class="form-horizontal">

Check out this demo.

When in doubt, inspect in Chrome or use Firebug in Firefox to figure out things like padding and margins. Using .row within the form fails in edsioufi's fiddle because .row uses negative left and right margins thereby drawing the horizontal bounds of the divs classed .row beyond the bounds of the containing fieldsets.

Another option is an interesting open source project called ScriptCS. It uses some crafty techniques to allow you a development experience outside of Visual Studio while still being able to leverage NuGet to manage your dependencies. It's free, very easy to install using Chocolatey. You can check it out here http://scriptcs.net.

Another cool feature it has is the REPL from the command line. Which allows you to do stuff like this:

C:\> scriptcs
scriptcs (ctrl-c or blank to exit)

> var message = "Hello, world!";
> Console.WriteLine(message);
Hello, world!
> 

C:\>

You can create C# utility "scripts" which can be anything from small system tasks, to unit tests, to full on Web APIs. In the latest release I believe they're also allowing for hosting the runtime in your own apps.

Check out it development on the GitHub page too https://github.com/scriptcs/scriptcs

There is an example in the launcher app of Android (that I've made a library out of it, here), inside the class that handles wallpapers-picking ("WallpaperPickerActivity") .

The example shows that you need to set a customized theme for this to work. Sadly, this worked for me only using the normal framework, and not the one of the support library.

Here're the themes:

styles.xml

 <style name="Theme.WallpaperPicker" parent="Theme.WallpaperCropper">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:colorBackgroundCacheHint">@null</item>
    <item name="android:windowShowWallpaper">true</item>
  </style>

  <style name="Theme.WallpaperCropper" parent="@android:style/Theme.DeviceDefault">
    <item name="android:actionBarStyle">@style/WallpaperCropperActionBar</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowActionBarOverlay">true</item>
  </style>

  <style name="WallpaperCropperActionBar" parent="@android:style/Widget.DeviceDefault.ActionBar">
    <item name="android:displayOptions">showCustom</item>
    <item name="android:background">#88000000</item>
  </style>

value-v19/styles.xml

 <style name="Theme.WallpaperCropper" parent="@android:style/Theme.DeviceDefault">
    <item name="android:actionBarStyle">@style/WallpaperCropperActionBar</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowActionBarOverlay">true</item>
    <item name="android:windowTranslucentNavigation">true</item>
  </style>

  <style name="Theme" parent="@android:style/Theme.DeviceDefault.Wallpaper.NoTitleBar">
    <item name="android:windowTranslucentStatus">true</item>
    <item name="android:windowTranslucentNavigation">true</item>
  </style>

EDIT: there is a better way to do it, which works on the support library too. Just add this line of code instead of what I've written above:

getSupportActionBar().setDisplayShowCustomEnabled(true);

Python 3:

user225312's answer is correct:

A. To count number of characters in str object, you can use len() function:

>>> print(len('please anwser my question'))
25

B. To get memory size in bytes allocated to store str object, you can use sys.getsizeof() function

>>> from sys import getsizeof
>>> print(getsizeof('please anwser my question'))
50

Python 2:

It gets complicated for Python 2.

A. The len() function in Python 2 returns count of bytes allocated to store encoded characters in a str object.

Sometimes it will be equal to character count:

>>> print(len('abc'))
3

But sometimes, it won't:

>>> print(len('???'))  # String contains Cyrillic symbols
6

That's because str can use variable-length encoding internally. So, to count characters in str you should know which encoding your str object is using. Then you can convert it to unicode object and get character count:

>>> print(len('???'.decode('utf8'))) #String contains Cyrillic symbols 
3

B. The sys.getsizeof() function does the same thing as in Python 3 - it returns count of bytes allocated to store the whole string object

>>> print(getsizeof('???'))
27
>>> print(getsizeof('???'.decode('utf8')))
32

In addition to the answer of "dasblinkenlight" I think an example could help. I will only use 8 bits for a better understanding.

x & 1 produces a value that is either 1 or 0, depending on the least significant bit of x: if the last bit is 1, the result of x & 1 is 1; otherwise, it is 0. This is a bitwise AND operation.

This is because 1 will be represented in bits as 00000001. Only the last bit is set to 1. Let's assume x is 185 which will be represented in bits as 10111001. If you apply a bitwise AND operation on x with 1 this will be the result:

00000001
10111001
--------
00000001

The first seven bits of the operation result will be 0 after the operation and will carry no information in this case (see Logical AND operation). Because whatever the first seven bits of the operand x were before, after the operation they will be 0. But the last bit of the operand 1 is 1 and it will reveal if the last bit of operand x was 0 or 1. So in this example the result of the bitwise AND operation will be 1 because our last bit of x is 1. If the last bit would have been 0, then the result would have been also 0, indicating that the last bit of operand x is 0:

00000001
10111000
--------
00000000

x >>= 1 means "set x to itself shifted by one bit to the right". The expression evaluates to the new value of x after the shift

Let's pick the example from above. For x >>= 1 this would be:

10111001
--------
01011100

And for left shift x <<= 1 it would be:

10111001
--------
01110010

Please pay attention to the note of user "dasblinkenlight" in regard to shifts.

ok just my two cents, use a is string method:

public static boolean isString(Object thing) {
    return thing instanceof String;
}

public void someMethod(Object thing){
    if (!isString(thing)) {
        return null;
    }
    log.debug("my thing is valid");
}

Enumerator includes Enumerable. Since 2.1, Enumerable also has a method #to_h. That's why, we can write :-

a = ["item 1", "item 2", "item 3", "item 4"]
a.each_slice(2).to_h
# => {"item 1"=>"item 2", "item 3"=>"item 4"}

Because #each_slice without block gives us Enumerator, and as per the above explanation, we can call the #to_h method on the Enumerator object.

sudo. su. chmod 04500. (setuid() & seteuid(), but they require you to already be root. E..g. chmod'ed 04***.)

Take care. These can open "interesting" security holes...

Depending on what you are doing, you may not need root. (For instance: I'll often chmod/chown /dev devices (serial ports, etc) (under sudo root) so I can use them from my software without being root. On the other hand, that doesn't work so well when loading/unloading kernel modules...)

INSERT INTO Table1 (Column1) VALUES ('John''s')

Or you can use a stored procedure and pass the parameter as -

usp_Proc1 @Column1 = 'John''s'

If you are using an INSERT query and not a stored procedure, you'll have to escape the quote with two quotes, else its OK if you don't do it.

The problem you have is related to TCP streaming nature.

The fact that you sent 100 Bytes (for example) from the server doesn't mean you will read 100 Bytes in the client the first time you read. Maybe the bytes sent from the server arrive in several TCP segments to the client.

You need to implement a loop in which you read until the whole message was received. Let me provide an example with DataInputStream instead of BufferedinputStream. Something very simple to give you just an example.

Let's suppose you know beforehand the server is to send 100 Bytes of data.

In client you need to write:

byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";

try 
{
    DataInputStream in = new DataInputStream(clientSocket.getInputStream());

    while(!end)
    {
        int bytesRead = in.read(messageByte);
        dataString += new String(messageByte, 0, bytesRead);
        if (dataString.length == 100)
        {
            end = true;
        }
    }
    System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
    e.printStackTrace();
}

Now, typically the data size sent by one node (the server here) is not known beforehand. Then you need to define your own small protocol for the communication between server and client (or any two nodes) communicating with TCP.

The most common and simple is to define TLV: Type, Length, Value. So you define that every message sent form server to client comes with:

• 1 Byte indicating type (For example, it could also be 2 or whatever).
• 1 Byte (or whatever) for length of message
• N Bytes for the value (N is indicated in length).

So you know you have to receive a minimum of 2 Bytes and with the second Byte you know how many following Bytes you need to read.

This is just a suggestion of a possible protocol. You could also get rid of "Type".

So it would be something like:

byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";

try 
{
    DataInputStream in = new DataInputStream(clientSocket.getInputStream());
    int bytesRead = 0;

    messageByte[0] = in.readByte();
    messageByte[1] = in.readByte();

    int bytesToRead = messageByte[1];

    while(!end)
    {
        bytesRead = in.read(messageByte);
        dataString += new String(messageByte, 0, bytesRead);
        if (dataString.length == bytesToRead )
        {
            end = true;
        }
    }
    System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
    e.printStackTrace();
}

The following code compiles and looks better. It assumes the first two bytes providing the length arrive in binary format, in network endianship (big endian). No focus on different encoding types for the rest of the message.

import java.nio.ByteBuffer;
import java.io.DataInputStream;
import java.net.ServerSocket;
import java.net.Socket;

class Test
{
    public static void main(String[] args)
    {
        byte[] messageByte = new byte[1000];
        boolean end = false;
        String dataString = "";

        try 
        {
            Socket clientSocket;
            ServerSocket server;

            server = new ServerSocket(30501, 100);
            clientSocket = server.accept();

            DataInputStream in = new DataInputStream(clientSocket.getInputStream());
            int bytesRead = 0;

            messageByte[1] = in.readByte();
            ByteBuffer byteBuffer = ByteBuffer.wrap(messageByte, 0, 2);

            int bytesToRead = byteBuffer.getShort();
            System.out.println("About to read " + bytesToRead + " octets");

            //The following code shows in detail how to read from a TCP socket

            while(!end)
            {
                bytesRead = in.read(messageByte);
                dataString += new String(messageByte, 0, bytesRead);
                if (dataString.length() == bytesToRead )
                {
                    end = true;
                }
            }

            //All the code in the loop can be replaced by these two lines
            //in.readFully(messageByte, 0, bytesToRead);
            //dataString = new String(messageByte, 0, bytesToRead);

            System.out.println("MESSAGE: " + dataString);
        }

            e.printStackTrace();
        }
    }
}

So the way I would solve this problem is to make sure the two datetimes are in the right timezone.

I can see that you are using datetime.now() which will return the systems current time, with no tzinfo set.

tzinfo is the information attached to a datetime to let it know what timezone it is in. If you are using naive datetime you need to be consistent through out your system. I would highly recommend only using datetime.utcnow()

seeing as somewhere your are creating datetime that have tzinfo associated with them, what you need to do is make sure those are localized (has tzinfo associated) to the correct timezone.

Take a look at Delorean, it makes dealing with this sort of thing much easier.

You can just pass the column names as a list with specifying the axis as 0 or 1

• axis=1: Along the Rows
• axis=0: Along the Columns

• By default axis=0

  data.drop(["Colname1","Colname2","Colname3","Colname4"],axis=1)

public class RequestHeadersNetworkInterceptor implements Interceptor {

    private final Map<String, String> headers;

    public RequestHeadersNetworkInterceptor(@NonNull Map<String, String> headers) {
        this.headers = headers;
    }

                continue;
            }
            if (header.getValue() == null || header.getValue().trim().isEmpty()) {
                builder.removeHeader(header.getKey());

        put("Accept", "application/json");

Android SDK Build Tools are exactly what the name says they are; tools for building Android Applications.It is very important to use the latest build tools version (selected automatically by your IDE via the Android SDK) but the reason the old versions are left there is to support backward compatibility, that is If your projects depend on older versions of the Build Tools.

Date.prototype.addHours= function(h){
    this.setHours(this.getHours()+h);
    return this;
}

Test:

alert(new Date().addHours(4));

If you want to set null value using update query set column value to NULL (without quotes) update tablename set columnname = NULL

However, if you are directly editing field value inside mysql workbench then use (Esc + del) keystroke to insert null value into selected column

I fixed it by adding .encode("utf-8") to soup.

That means that print(soup) becomes print(soup.encode("utf-8")).

It`s possible to use MySQL specific syntax sugar:

SELECT ... date_field + INTERVAL 1 DAY

Looks much more pretty instead of DATE_ADD function

Below is an example of such a query:

INSERT INTO [93275].[93276].[93277].[93278] ( [Mobile Number], [Mobile Series], [Full Name], [Full Address], [Active Date], company ) IN 'I:\For Test\90-Mobile Series.accdb
SELECT [1].[Mobile Number], [1].[Mobile Series], [1].[Full Name], [1].[Full Address], [1].[Active Date], [1].[Company Name]
FROM 1
WHERE ((([1].[Mobile Series])="93275" Or ([1].[Mobile Series])="93276")) OR ((([1].[Mobile Series])="93277"));OR ((([1].[Mobile Series])="93278"));

It is most likely due to a cross-origin request, but it may not be. For me, I had been debugging an API and had set the Access-Control-Allow-Origin to *, but it appears that recent versions of Chrome are requiring an extra header. Try prepending the following to your file if you are using PHP:

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");

Make sure that you haven't already used header in another file, or you will get a nasty error. See the docs for more.

It depends on the browser. If you look in the blog post Array.prototype.slice vs manual array creation, there is a rough guide to performance of each:

The command :hide will hide the currently focused window. I think this is the functionality you are looking for.

In order to navigate between windows type Ctrl+w followed by a navigation key (h,j,k,l, or arrow keys)

For more information run :help window and :help hide in vim.

1. Solution

Open Sublime Text console ? paste in opened field:

sublime.packages_path()

? Enter. You get result in console output.

2. Relevance

This answer is relevant for April 2018. In the future, the data of this answer may be obsolete.

3. Not recommended

I'm not recommended @osiris answer. Arguments:

1. In new versions of Sublime Text and/or operating systems (e.g. Sublime Text 4, macOS 14) paths may be changed.
2. It doesn't take portable Sublime Text on Windows. In portable Sublime Text on Windows another path of Packages folder.
3. It less simple.

Got it from another answer but the script works magic. :)

Add the following code before you instantiate your web service client:

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Or for backward compatibility with TLS 1.1 and prior:

System.Net.ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12; 

Window level vars are sorta like statics in the sense that you can use direct reference and these are available to all parts of your app

As far as I can remember, an array is actually a group of pointers. For example

p[1]== *(&p+1)

is a true statement

Another option could be:

var initial = function() {
    console.log( 'initial function!' );
}

var iWantToExecuteThisOneToo = function () {
    console.log( 'the other function that i wanted to execute!' );
}

function extendFunction( oldOne, newOne ) {
    return (function() {
        oldOne();
        newOne();
    })();
}

var extendedFunction = extendFunction( initial, iWantToExecuteThisOneToo );

An alternative solution would be to use the Url helper object to set the href attribute of an <a> tag like:

<a href="@Url.Action("Details", "Product",new { id=item.ID }) )">Details</a>

{ flex: 1, height: undefined, width: undefined, resizeMode: 'contain' }

If you are using these attributes in your style prop in the <Image /> and the image is disappeared.

Put your image into a <View> tag. Like this:

<View 
  style={{
      width: '100%',
     height: '30%'
     }}
>
          <Image
            source={require('../logo.png')}
            style={{
              flex: 1,
              height: undefined,
              width: undefined,
              resizeMode: 'contain'
            }}
            resizeMode={'cover'}
          />
</View>

Give your view the width and height you want.

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

var ref = new Firebase('https://your.firebaseio.com/');

Query query = ref.orderByChild('genre').equalTo('comedy');
query.addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        for (DataSnapshot movieSnapshot : dataSnapshot.getChildren()) {
            Movie movie = dataSnapshot.getValue(Movie.class);
            if (movie.getLead().equals('Jack Nicholson')) {
                console.log(movieSnapshot.getKey());
            }
        }

If you are uploading a zip file. Make sure that you are zipping the contents of the directory and not the directory itself.

It depends on what you want to test:

• for a string, you can use If strName = vbNullString or IF strName = "" or Len(strName) = 0 (last one being supposedly faster)
• for an object, you can use If myObject is Nothing
• for a recordset field, you could use If isnull(rs!myField)
• for an Excel cell, you could use If range("B3") = "" or IsEmpty(myRange)

Extended discussion available here (for Access, but most of it works for Excel as well).

Oracle, along with other databases, analyzes a given query to create an execution plan. This plan is the most efficient way of retrieving the data.

Oracle provides the 'explain plan' statement which analyzes the query but doesn't run it, instead populating a special table that you can query (the plan table).

The syntax (simple version, there are other options such as to mark the rows in the plan table with a special ID, or use a different plan table) is:

explain plan for <sql query>

The analysis of that data is left for another question, or your further research.

You have multiple columns named the same thing in your inner query, so the error is raised in the outer query. If you get rid of the outer query, it should run, although still be confusing:

SELECT DISTINCT
    coaches.id,
    people.*,
    users.*,
    coaches.*
FROM "COACHES"
    INNER JOIN people ON people.id = coaches.person_id
    INNER JOIN users ON coaches.person_id = users.person_id
    LEFT OUTER JOIN organizations_users ON organizations_users.user_id = users.id
WHERE
    rownum <= 25

It would be much better (for readability and performance both) to specify exactly what fields you need from each of the tables instead of selecting them all anyways. Then if you really need two fields called the same thing from different tables, use column aliases to differentiate between them.

You can do something like this to include IE-specific javascript:

<!--[IF IE]>
    <script type="text/javascript">
        // IE stuff
    </script>
<![endif]-->

You probably need to open a command prompt with the PATH set up properly. Look for an icon in the start menu that says something like "Visual C++ 2005 Command Prompt". You should be able to run dumpbin (and all the other command line tools) from there.

Try this:

var i, j;

for (i = 0; i < cubes.length; i++) {
    for (j = 0; j < cubes[i].length; j++) {
       do whatever with cubes[i][j];
    }
}

Just throw some light in to some issues related to this control.

Date picker is not a standard control that comes with office package. So developers encountered issues like missing date picker controls when application deployed in some other machiens/versions of office. In order to use it you have to activate the reference to the .dll, .ocx file that contains it.

In the event of a missing date picker, you have to replace MSCOMCT2.OCX file in System or System32 directory and register it properly. Try this link to do the proper replacement of the file.

In the VBA editor menu bar-> select tools-> references and then find the date picker reference and check it.

If you need the file, download MSCOMCT2.OCX from here.

When you loop in an array like you did, your for variable(in this example i) is current element of your array.

For example if your ar is [1,5,10], the i value in each iteration is 1, 5, and 10. And because your array length is 3, the maximum index you can use is 2. so when i = 5 you get IndexError. You should change your code into something like this:

for i in ar:
    theSum = theSum + i

Or if you want to use indexes, you should create a range from 0 ro array length - 1.

for i in range(len(ar)):
    theSum = theSum + ar[i]

You create an empty project in gitlab then on your local terminal follow one of these:

Push an existing folder

cd existing_folder
git init
git remote add origin [email protected]:GITLABUSERNAME/YOURGITPROJECTNAME.git
git add .
git commit -m "Initial commit"
git push -u origin master

Push an existing Git repository

cd existing_repo
git remote rename origin old-origin
git remote add origin [email protected]:GITLABUSERNAME/YOURGITPROJECTNAME.git
git push -u origin --all
git push -u origin --tags

If you know the name of the filters, you can do it in a line.

users = users.filter(obj => obj.name == filter.name && obj.address == filter.address)

I did not find my solution here, maybe someone will be useful:

.child-with-overflowed-text{
  word-wrap: break-all;
}

Good luck!

Trello.com Trello is free for unlimited users. Period.

You almost definitely don't need "Sub-cards". Use the checklists instead, or if you REALLY need sub-cards, don't have a parent sub-card. Just name the tickets something like "Epic - Story A" or "Story - task Z" or whatever.

Another idea is to create two boards (did I mention you can have unlimited boards for free too?). One for your epics and one for your stories. Call one your product management board and the other your sprint board, or whatever you like.

I'm not sure what you need different roles for - but, people aren't crazy - they know their job. As a startup if you already have problems getting people to not do crazy things (Where you need to restrict their permissions) you have much much bigger issues.

The point is that you need a SMALL tool to help you track stuff. Not a super rigid tool that makes you work in a super specific way. As a new (I assume?) startup, you should let your process grow into a tool. Don't beef up your process to fit a tool.

new WindowSettings();

You just closed a brand new instance of the form that wasn't visible in the first place.

You need to close the original instance of the form by accepting it as a constructor parameter and storing it in a field.

Try Shift-Tab-Tab a bigger documentation appears, than with Shift-Tab. It's the same but you can scroll down.

Shift-Tab-Tab-Tab and the tooltip will linger for 10 seconds while you type.

Shift-Tab-Tab-Tab-Tab and the docstring appears in the pager (small part at the bottom of the window) and stays there.

Lets say your company makes 4 different products, your client has another 3 different products from another 3 different companies.

Someday the client thought, why don't we integrate all our systems into one huge system. Ten minutes later their IT department said that will take 2 years.

You (the wise developer) said, why don't we just integrate all the different systems and make them work together in a homogeneous environment? The client manager staring at you... You continued, we will use a Middleware, we will study the Inputs/Outputs of all different systems, the resources they use and then choose an appropriate Middleware framework.

Still explaining to the non tech manager
With Middleware framework in the middle, the first system will produce X stuff, the system Y and Z would consume those outputs and so on.

If you have the HTML

<form name="formname" .... id="form-first">
    <iframe id="one" src="iframe2.html">
    </iframe>
</form>

and JavaScript

function iframeRef( frameRef ) {
    return frameRef.contentWindow
        ? frameRef.contentWindow.document
        : frameRef.contentDocument
}

var inside = iframeRef( document.getElementById('one') )

inside is now a reference to the document, so you can do getElementsByTagName('textarea') and whatever you like, depending on what's inside the iframe src.

Because nobody mentioned it:

show table status;

lists all tables along with some additional information, including estimated rows for each table. This is what phpMyAdmin is using for its database page.

This information is available in MySQL 4, probably in MySQL 3.23 too - long time prior information schema database.

UPDATE:

Because there was down-vote, I want to clarify that the number shown is estimated for InnoDB and TokuDB and it is absolutely correct for MyISAM and Aria (Maria) storage engines.

Per the documentation:

The number of rows. Some storage engines, such as MyISAM, store the exact count. For other storage engines, such as InnoDB, this value is an approximation, and may vary from the actual value by as much as 40% to 50%. In such cases, use SELECT COUNT(*) to obtain an accurate count.

This also is fastest way to see the row count on MySQL, because query like:

select count(*) from table;

Doing full table scan what could be very expensive operation that might take hours on large high load server. It also increase disk I/O.

The same operation might block the table for inserts and updates - this happen only on exotic storage engines.

InnoDB and TokuDB are OK with table lock, but need full table scan.

There's a headers parameter in the config object you pass to $http for per-call headers:

$http({method: 'GET', url: 'www.google.com/someapi', headers: {
    'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
});

Or with the shortcut method:

$http.get('www.google.com/someapi', {
    headers: {'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
});

The list of the valid parameters is available in the $http service documentation.

You could send yourself an email an look in the email header (In Outlook: Open the mail, View->Options, there is 'Internet headers)

You can also use an exit variable if you want your code to be a bit more readable:

DECLARE @Flag int = 0
DECLARE @Done bit = 0

WHILE @Done = 0 BEGIN
    SET @Flag = @Flag + 1
    PRINT @Flag
    IF @Flag >= 5 SET @Done = 1
END

This would probably be more relevant when you have a more complicated loop and are trying to keep track of the logic. As stated loops are expensive so try and use other methods if you can.

for (int i = 0; i < dataGridView2.Rows.Count; i++)
{
SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=ID_Proof;Integrated Security=True");
                        SqlCommand cmd = new SqlCommand("INSERT INTO Restaurant (Customer_Name,Quantity,Price,Category,Subcategory,Item,Room_No,Tax,Service_Charge,Service_Tax,Order_Time) values (@customer,@quantity,@price,@category,@subcategory,@item,@roomno,@tax,@servicecharge,@sertax,@ordertime)", con);
                        cmd.Parameters.AddWithValue("@customer",dataGridView2.Rows[i].Cells[0].Value);
                        cmd.Parameters.AddWithValue("@quantity",dataGridView2.Rows[i].Cells[1].Value);
                        cmd.Parameters.AddWithValue("@price",dataGridView2.Rows[i].Cells[2].Value);
                        cmd.Parameters.AddWithValue("@category",dataGridView2.Rows[i].Cells[3].Value);
                        cmd.Parameters.AddWithValue("@subcategory",dataGridView2.Rows[i].Cells[4].Value);
                        cmd.Parameters.AddWithValue("@item",dataGridView2.Rows[i].Cells[5].Value);
                        cmd.Parameters.AddWithValue("@roomno",dataGridView2.Rows[i].Cells[6].Value);
                        cmd.Parameters.AddWithValue("@tax",dataGridView2.Rows[i].Cells[7].Value);
                        cmd.Parameters.AddWithValue("@servicecharge",dataGridView2.Rows[i].Cells[8].Value);
                        cmd.Parameters.AddWithValue("@sertax",dataGridView2.Rows[i].Cells[9].Value);
                        cmd.Parameters.AddWithValue("@ordertime",dataGridView2.Rows[i].Cells[10].Value);
                        con.Open();
                        cmd.ExecuteNonQuery();
                        con.Close();
                        MessageBox.Show("Added successfully!");

Honestly, this is the sort of situation where I just open up Python on the command line and start messing around:

 >>> x = "Dana Larose is playing with find()"
 >>> x.find("Dana")
 0
 >>> x.find("ana")
 1
 >>> x.find("La")
 5
 >>> x.find("La", 6)
 -1

Python's interpreter makes this sort of experimentation easy. (Same goes for other languages with a similar interpreter)

Both do the same on all browsers, AFAIK. Checked on Chrome and Firefox, both append display:none to the style attribute of the element.

You have to store the content as a fact:

- set_fact:
    string_to_echo: "{{ command_output.stdout }}"

The best solution I have found that Works:

Connect your device thru USB

And type these commands:

1. rvictl -s UDID - (id of device 20 chars, you can locate 4t in iTunes or organiser in Xcode)

2. sudo launchctl list com.apple.rpmuxd

3. sudo tcpdump -n -t -i rvi0 -q tcp
   OR just sudo tcpdump -i rvi0 -n

If rvictl is not working install Xcode

datetime.datetime.fromtimestamp() is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp() expects Unix timestamp, in seconds.

Do it like that:

>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)

and the result is:

>>> date
datetime.datetime(2012, 3, 16, 1, 0)

Does it answer your question?

EDIT: J.F. Sebastian correctly suggested to use true division by 1e3 (float 1000). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int when dividing (using / operator) int by int (this is called floor division). By replacing the divisor 1000 (being an int) with the 1e3 divisor (being representation of 1000 as float) or with float(1000) (or 1000. etc.), the division becomes true division. Python 2.x returns float when dividing int by float, float by int, float by float etc. And when there is some fractional part in the timestamp passed to fromtimestamp() method, this method's result also contains information about that fractional part (as the number of microseconds).

Addition to @jwize's answer

Because angular.element(document).injector() was giving error injector is not defined So, I have created function that you can run after AJAX call or when DOM is changed using jQuery.

  function compileAngularElement( elSelector) {

        var elSelector = (typeof elSelector == 'string') ? elSelector : null ;  
            // The new element to be added
        if (elSelector != null ) {
            var $div = $( elSelector );

                // The parent of the new element
                var $target = $("[ng-app]");

              angular.element($target).injector().invoke(['$compile', function ($compile) {
                        var $scope = angular.element($target).scope();
                        $compile($div)($scope);
                        // Finally, refresh the watch expressions in the new element
                        $scope.$apply();
                    }]);
            }

        }

use it by passing just new element's selector. like this

compileAngularElement( '.user' ) ; 

You can do it like this,

<input type="text" name="name" value="<?php echo $name;?>" />

But seen as you've taken it straight from user input, you want to sanitize it first so that nothing nasty is put into the output of your page.

<input type="text" name="name" value="<?php echo htmlspecialchars($name);?>" />
