A subclass does not inherit the private members of its parent class. However, if the superclass has public or protected methods for accessing its private fields, these can also be used by the subclass.

import java.util.ArrayList;

public class TestClass {

public static void main(String[] args) {

    ArrayList<ArrayList<String>> listOLists = new ArrayList<ArrayList<String>>();
    ArrayList<String> List_1 = new ArrayList<String>();
    List_1.add("1");
    List_1.add("2");
    listOLists.add(List_1);

    ArrayList<String> List_2 = new ArrayList<String>();
    List_2.add("4");
    List_2.add("5");
    List_2.add("10");
    List_2.add("11");
    listOLists.add(List_2);
    for (int i = 0; i < listOLists.size(); i++) {
        System.out.print("list " + i + " :");
        for (int j = 0; j < listOLists.get(i).size(); j++) {
            System.out.print(listOLists.get(i).get(j) + " ;");
        }
        System.out.println();
    }

}

}

I hope this solution gives a better picture of list if lists

"At run time, the authorization module iterates through the allow and deny elements, starting at the most local configuration file, until the authorization module finds the first access rule that fits a particular user account. Then, the authorization module grants or denies access to a URL resource depending on whether the first access rule found is an allow or a deny rule. The default authorization rule is . Thus, by default, access is allowed unless configured otherwise."

Article at MSDN

deny = * means deny everyone
deny = ? means deny unauthenticated users

In your 1st example deny * will not affect dan, matthew since they were already allowed by the preceding rule.

According to the docs, here is no difference in your 2 rule sets.

I just want to say guys:

Only Play With Margin

It is a lot easier to add space between <li> if you play with margin.

Why are you not using this?

int[] array = { 12, 56, 89, 65, 61, 36, 45, 23 };
int max = array.Max();
int min = array.Min();

DateTime.DaysInMonth(DateTime.Now.Year, DateTime.Now.Month)

Since Java 1.6, there is ArrayDeque, which implements Queue and seems to be faster and more memory efficient than a LinkedList and doesn't have the thread synchronization overhead of the ArrayBlockingQueue: from the API docs: "This class is likely to be faster than Stack when used as a stack, and faster than LinkedList when used as a queue."

final Queue<Object> q = new ArrayDeque<Object>();
q.add(new Object()); //insert element
q.poll(); //remove element

The Best Command for changing branch

git branch -M YOUR_BRANCH

Have you considered using this.props.navigation.replace( "HomeScreen" ) instead of this.props.navigation.navigate( "HomeScreen" ).

This way you are not adding anything to the stack. so HomeScreen won't wave anything to go back to if back button pressed in Android or screen swiped to the right in IOS.

More informations check the Documentation. And of course you can hide the back button by setting headerLeft: null in navigationOptions

Another possibility to make composer think you're using the correct version of PHP is to add to the config section of a composer.json file a platform option, like this:

"config": {
    "platform": {
        "php": "<ver>"
    }
},

Where <ver> is the PHP version of your choice.

Snippet from the docs:

Lets you fake platform packages (PHP and extensions) so that you can emulate a production env or define your target platform in the config. Example: {"php": "7.0.3", "ext-something": "4.0.3"}.

if you have ID or any specific field in your item, you can use filter(). its act like Where().

<a class="btn" ng-click="remove(item)">Delete</a>

in controller:

$scope.remove = function(item) { 
  $scope.bdays = $scope.bdays.filter(function (element) {
                    return element.ID!=item.ID
                });
}

Or just...

var response = (function() {
    var a;
    // calculate a
    return a;
})();  

In this case, the response variable receives the return value of the function. The function executes immediately.

You can use this construct if you want to populate a variable with a value that needs to be calculated. Note that all calculation happens inside the anonymous function, so you don't pollute the global namespace.

Another option is using System.IO.File.AppendText

This is equivalent to the StreamWriter overloads others have given.

Also File.AppendAllText may give a slightly easier interface without having to worry about opening and closing the stream. Though you may need to then worry about putting in your own linebreaks. :)

On my system, Ctrl+click brings up the right-click menu instead of opening the declaration. However, if you hold Ctrl and hover the mouse pointer over the variable/class/method name, a small boxed menu appears with "open declaration" at the top. You can move the pointer down and click that item to get the desired effect.

I'm running Ubuntu 14.04 through VMWare on OS X.

I had a different scenario, but still landed on this answer.
I had imported my root project folder containing multiple Maven projects but also some other stuff used in this project.
IntelliJ recognised the Java files, but didn't resolve the Maven dependencies.

I fixed this by performing a right-click on each pom and then "Add as maven project"

The error is coming as your query is getting formed as

SELECT * FROM Employ where number = parseInt(val);

I dont know which DB you are using but no DB will understand parseInt.

What you can do is use a variable say temp and store the value of parseInt(val) in temp variable and make the query as

SELECT * FROM Employ where number = temp;

If you don't mind being a bit cryptic you can simly roll with 0 < (a + b + c) < 3 which will return true if you have between one and two true statements and false if all are false or none is false.

This also simplifies if you use functions to evaluate the bools as you only evaluate the variables once and which means you can write the functions inline and do not need to temporarily store the variables. (Example: 0 < ( a(x) + b(x) + c(x) ) < 3.)

The explanation for this behavior is right in the javadoc for afterExecute:

Note: When actions are enclosed in tasks (such as FutureTask) either explicitly or via methods such as submit, these task objects catch and maintain computational exceptions, and so they do not cause abrupt termination, and the internal exceptions are not passed to this method.

Some RFID chips are read-write, the majority are read-only. You can find out if your chip is read-only by checking the datasheet.

Description:

there are 3 steps to run PHP code inside post or page.

1. In functions.php file (in your theme) add new function

2. In functions.php file (in your theme) register new shortcode which call your function:

add_shortcode( 'SHORCODE_NAME', 'FUNCTION_NAME' );

3. use your new shortcode

Example #1: just display text.

In functions:

function simple_function_1() {
    return "Hello World!";
}

add_shortcode( 'own_shortcode1', 'simple_function_1' );

In post/page:

[own_shortcode1]

Effect:

Hello World!

Example #2: use for loop.

In functions:

function simple_function_2() {
    $output = "";
    
    for ($number = 1; $number < 10; $number++) {    
        // Append numbers to the string
        $output .= "$number<br>";
    } 
    
    return "$output";
}

add_shortcode( 'own_shortcode2', 'simple_function_2' );

In post/page:

[own_shortcode2]

Effect:

1
2
3
4
5
6
7
8
9

Example #3: use shortcode with arguments

In functions:

function simple_function_3($name) {
    return "Hello $name";
}

add_shortcode( 'own_shortcode3', 'simple_function_3' );

In post/page:

[own_shortcode3 name="John"]

Effect:

Hello John

Example #3 - without passing arguments

In post/page:

[own_shortcode3]

Effect:

Hello 

If you mean using a literal, you simply have to create a binary string:

insert into Files (FileId, FileData) values (1, 0x010203040506)

And you will have a record with a six byte value for the FileData field.

You indicate in the comments that you want to just specify the file name, which you can't do with SQL Server 2000 (or any other version that I am aware of).

You would need a CLR stored procedure to do this in SQL Server 2005/2008 or an extended stored procedure (but I'd avoid that at all costs unless you have to) which takes the filename and then inserts the data (or returns the byte string, but that can possibly be quite long).

In regards to the question of only being able to get data from a SP/query, I would say the answer is yes, because if you give SQL Server the ability to read files from the file system, what do you do when you aren't connected through Windows Authentication, what user is used to determine the rights? If you are running the service as an admin (God forbid) then you can have an elevation of rights which shouldn't be allowed.

Got it.

sort(mMyClassVector.begin(), mMyClassVector.end(), 
    [](const MyClass & a, const MyClass & b) -> bool
{ 
    return a.mProperty > b.mProperty; 
});

I assumed it'd figure out that the > operator returned a bool (per documentation). But apparently it is not so.

Try using an ImageList

ImageList imgList = new ImageList;

imgList.TransparentColor = Color.White;

Load the image like this:

picturebox.Image = imgList.Images[img_index];

Code for WebTestPlugIn

public class Protocols : WebTestPlugin
{

    public override void PreRequest(object sender, PreRequestEventArgs e)
    {
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

    }

}

I accidentally named the js file .min instead of .min.js ...

Try to run below example in order to feel how the magical variables work.

@echo off

SETLOCAL EnableDelayedExpansion

echo Full path and filename: %~f0
echo Drive: %~d0
echo Path: %~p0
echo Drive and path: %~dp0
echo Filename without extension: %~n0
echo Filename with    extension: %~nx0
echo Extension: %~x0

echo date time : %~t0
echo file size: %~z0

ENDLOCAL

The related rules are following.

%~I         - expands %I removing any surrounding quotes ("")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

If you have already got the cursor, then this is how you may get the last record from cursor:

cursor.moveToPosition(cursor.getCount() - 1);
//then use cursor to read values

Depending on your project, you might want to consider using EditorConfig (https://editorconfig.org/). There's a Notepad++ plugin which will load an .editorconfig where you can specify "lf" as the mandatory line ending.

I've only started using it, but it's nice so far, and open source projects I've worked on have included .editorconfig files for years. The "EOL Conversion" setting isn't changed, so it can be a bit confusing, but if you "View > Show Symbol > Show End of Line", you can see that it's adding LF instead of CRLF, even when "EOL Conversion" and the lower bottom corner shows something else (e.g. Windows (CR LF)).

If you start tinkering with VirtualBox network settings, watch out for this: you might make new network adapters (eth1, eth2), yet have your /etc/network/interfaces still configured for eth0.

Diagnose:

ethtool -i eth0
Cannot get driver information: no such device

Find your interfaces:

ls /sys/class/net
eth1 eth2 lo

Fix it:

Edit /etc/networking/interfaces and replace eth0 with the appropriate interface name (e.g eth1, eth2, etc.)

:%s/eth0/eth2/g

Are they identical?

> identical(A,C)
[1] FALSE

Which elements disagree:

> which(A != C)
[1] 2 4

Try this. It uses the split function which is a core part of javascript, nothing to do with jQuery.

var parts = html.split(":-"),
    i, l
;
for (i = 0, l = parts.length; i < l; i += 2) {
    $("#" + parts[i]).text(parts[i + 1]);
}

Floating point numbers are encoded using an exponential form, that is something like m * b ^ e, i.e. not like integers at all. The question you ask would be meaningful in the context of fixed point numbers. There are numerous fixed point arithmetic libraries available.

Regarding floating point arithmetic: The number of decimal digits depends on the presentation and the number system. For example there are periodic numbers (0.33333) which do not have a finite presentation in decimal but do have one in binary and vice versa.

Also it is worth mentioning that floating point numbers up to a certain point do have a difference larger than one, i.e. value + 1 yields value, since value + 1 can not be encoded using m * b ^ e, where m, b and e are fixed in length. The same happens for values smaller than 1, i.e. all the possible code points do not have the same distance.

Because of this there is no precision of exactly n digits like with fixed point numbers, since not every number with n decimal digits does have a IEEE encoding.

There is a nearly obligatory document which you should read then which explains floating point numbers: What every computer scientist should know about floating point arithmetic.

When spring instantiates beans, it looks for a couple of interfaces like ApplicationContextAware and InitializingBean. If they are found, the methods are invoked. E.g. (very simplified)

Class<?> beanClass = beanDefinition.getClass();
Object bean = beanClass.newInstance();
if (bean instanceof ApplicationContextAware) {
    ((ApplicationContextAware) bean).setApplicationContext(ctx);
}

Note that in newer version it may be better to use annotations, rather than implementing spring-specific interfaces. Now you can simply use:

@Inject // or @Autowired
private ApplicationContext ctx;

No, there is no such type. But there are some choices:

• Dynamically generated queries (sp_executesql)
• Temporary tables
• Table-type variables (closest thing that there is to a list)
• Create an XML string and then convert it to a table with the XML functions (really awkward and roundabout, unless you have an XML to start with)

None of these are really elegant, but that's the best there is.

Since array literal notation is still valid JSON, you can use JSON.parse() to convert that string into an array, and from there, use it's values.

var test = "[1,2]";
parsedTest = JSON.parse(test); //an array [1,2]

//access like and array
console.log(parsedTest[0]); //1
console.log(parsedTest[1]); //2

For AngularJS, you can use ng-class with a function like this:

HTML ->

<nav class="navbar navbar-default" ng-controller="NavCtrl as vm">
  <div class="container">
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav" >
        <li ng-class="vm.Helper.UpdateTabActive('Home')"><a href="#" ng-click>Home</a></li>
        <li ng-class="vm.Helper.UpdateTabActive('About')"><a href="#about">About</a></li>
        <li ng-class="vm.Helper.UpdateTabActive('Contact')"><a href="#contact">Contact</a></li>        
      </ul>
    </div>
</nav>

And controller

app.controller('NavCtrl', ['$scope', function($scope) {
    var vm = this;
    vm.Helper = {
        UpdateTabActive: function(sTab){
            return window.location.hash && window.location.hash.toLowerCase() == ("#/" + sTab).toLowerCase() ? 'active' : '';
        }
    }    
}]);

If you are using $location, then there won't be hash. So you can extract the required string from URL using $location

Following will not work in all cases -->

Using a scope variable like following will work only when clicked, but if the transition is done using $state.transitionTo or window.location or manually updating the URL, the Tab value will not be updated

<ul class="nav navbar-nav" ng-init="Tab='Home'">
   <li ng-class="Tab == 'Home' ? 'active' : ''"><a href="#" ng-click="Tab = 'Home'">Home</a></li>
   <li ng-class="Tab == 'About' ? 'active' : ''"><a href="#" ng-click="Tab = 'About'">About</a></li>
</ul>

You can use the file utility to give you an indication of the type of line endings.

Unix:

$ file testfile1.txt
testfile.txt: ASCII text

"DOS":

$ file testfile2.txt
testfile2.txt: ASCII text, with CRLF line terminators

To convert from "DOS" to Unix:

$ dos2unix testfile2.txt

To convert from Unix to "DOS":

$ unix2dos testfile1.txt

Converting an already converted file has no effect so it's safe to run blindly (i.e. without testing the format first) although the usual disclaimers apply, as always.

There is no built-in method, but there are several ways to do it. The most straightforward way that I can think of at the moment is:

1. Create a subclass of JComponent.
2. Override the paintComponent(Graphics g) method to paint the image that you want to display.
3. Set the content pane of the JFrame to be this subclass.

Some sample code:

class ImagePanel extends JComponent {
    private Image image;
    public ImagePanel(Image image) {
        this.image = image;
    }
    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.drawImage(image, 0, 0, this);
    }
}

// elsewhere
BufferedImage myImage = ImageIO.read(...);
JFrame myJFrame = new JFrame("Image pane");
myJFrame.setContentPane(new ImagePanel(myImage));

Note that this code does not handle resizing the image to fit the JFrame, if that's what you wanted.

df.insert(0, 'New_ID', range(880, 880 + len(df)))
df

You can choose the url where the form must be posted (and thus, the invoked action) in different ways, depending on the browser support:

• for newer browsers that support HTML5, you can use formaction attribute of a submit button
• for older browsers that don't support this, you need to use some JavaScript that changes the form's action attribute, when the button is clicked, and before submitting

In this way you don't need to do anything special on the server side.

Of course, you can use Url extensions methods in your Razor to specify the form action.

For browsers supporting HMTL5: simply define your submit buttons like this:

<input type='submit' value='...' formaction='@Url.Action(...)' />

For older browsers I recommend using an unobtrusive script like this (include it in your "master layout"):

$(document).on('click', '[type="submit"][data-form-action]', function (event) {
  var $this = $(this);
  var formAction = $this.attr('data-form-action');
  $this.closest('form').attr('action', formAction);
});

NOTE: This script will handle the click for any element in the page that has type=submit and data-form-action attributes. When this happens, it takes the value of data-form-action attribute and set the containing form's action to the value of this attribute. As it's a delegated event, it will work even for HTML loaded using AJAX, without taking extra steps.

Then you simply have to add a data-form-action attribute with the desired action URL to your button, like this:

<input type='submit' data-form-action='@Url.Action(...)' value='...'/>

Note that clicking the button changes the form's action, and, right after that, the browser posts the form to the desired action.

As you can see, this requires no custom routing, you can use the standard Url extension methods, and you have nothing special to do in modern browsers.

Getting an ECONNREFUSED errno means that your kernel was refused a connection at the other end, so if it's a bug, it's either in your kernel or in the other end. What you can do is to trap the error in a very specific way and try again in a little while, since this seems to work:

# This is Python > 2.5 code
import errno, time

for attempt in range(MAXIMUM_NUMBER_OF_ATTEMPTS):
    try:
        # your urllib call here
    except EnvironmentError as exc: # replace " as " with ", " for Python<2.6
        if exc.errno == errno.ECONNREFUSED:
            time.sleep(A_COUPLE_OF_SECONDS)
        else:
            raise # re-raise otherwise
    else: # we tried, and we had no failure, so
        break
else: # we never broke out of the for loop
    raise RuntimeError("maximum number of unsuccessful attempts reached")

Replace the two all-caps constants with your favourite numbers.

Suppose STUDENTID contains some characters or numbers that you already know i.e. 'searchstring' then below query will work for you.

You could try this:

select * from STUDENTS where CHARINDEX('searchstring',STUDENTID)>0

I think this one is the fastest and easiest one.

You calculate an average by adding all the elements and then dividing by the number of elements.

var total = 0;
for(var i = 0; i < grades.length; i++) {
    total += grades[i];
}
var avg = total / grades.length;

The reason you got 68 as your result is because in your loop, you keep overwriting your average, so the final value will be the result of your last calculation. And your division and multiplication by grades.length cancel each other out.

For documentation purpose, it's better to list the string values that are legal:

size: PropTypes.oneOfType([
    PropTypes.number,
    PropTypes.oneOf([ 'SMALL', 'LARGE' ]),
]),

List has Contains method that return bool. We can use that method in query.

List<int> listA = new List<int>();
List<int> listB = new List<int>();
listA.AddRange(new int[] { 1,2,3,4,5 });
listB.AddRange(new int[] { 3,5,6,7,8 });

var v = from x in listA
        where !listB.Contains(x)
        select x;

foreach (int i in v)
    Console.WriteLine(i);

I was looking for something like this and after some tries and falls i create my own makefile, I know that's not the "idiomatic way" but it's a begining to understand make and this works for me, maybe you could try in your project.

Have you tried HttpServerUtility.UrlDecode or HttpUtility.UrlDecode?

Another way to get Byte array from image path is

byte[] imgdata = System.IO.File.ReadAllBytes(HttpContext.Current.Server.MapPath(path));

Development teams should be segregated more often by technological/architectural layers instead of business function.

I come from a general culture where developers own "everything from web page to stored procedure". So in order to implement a feature in the system/application, they would prepare the database table schemas, write the stored procs, match the data access code, implement the business logic and web service methods, and the web page interfaces.

And guess what? Everybody has their own way to doing things! Everyone struggles to learn the ASP.NET AJAX and Telerik or Infragistic suites, Enterprise Library or other productivity and data layer and persistence frameworks, Aspect-oriented frameworks, logging and caching application blocks, DB2 or Oracle percularities. And guess what? Everybody takes heck of a long time to learn how to do things the proper way! Meaning, lots of mistakes in the meantime and plenty of resulting defects and performance bottlenecks! And heck of a longer time to fix them! Across each and every layer! Everybody has a hand in every Visual Studio project. Nobody is specialised to handle and optmise one problem/technology domain. Too many chefs spoil the soup. All the chefs result in some radioactive goo.

Developers may have cross-layer/domain responsibilities, but they should not pretend that they can be masters of all disciplines, and should be limited to only a few. In my experience, when a project is not a small one and utilises lots of technologies, covering more business functions in a single layer is more productive (as well as encouraging more test code test that layer) than covering less business functions spanning the entire architectural stack (which motivates developers to test only via their UI and not test code).

This is just how Response.Redirect(url, true) works. It throws the ThreadAbortException to abort the thread. Just ignore that exception. (I presume it is some global error handler/logger where you see it?)

As per my knowledge Inline sytle comes first so css class should not work.

Use Jquery as

$(document).ready(function(){

   $("#demoFour li").css("display","inline");
  });

You can also try 

#demoFour li { display:inline !important;}

I think you shouldn't prepend themesDir. You only pass the filename of the template to flask, it will then look in a folder called templates relative to your python file.

private static String getMessageDigest(String message, String algorithm) {
 MessageDigest digest;
 try {
  digest = MessageDigest.getInstance(algorithm);
  byte data[] = digest.digest(message.getBytes("UTF-8"));
  return convertByteArrayToHexString(data);
 } catch (NoSuchAlgorithmException | UnsupportedEncodingException e) {
  // TODO Auto-generated catch block

You can call above method with different algorithms like below.

Thank you for sharing this. I have it implemented and working. However:

1) I install ver 1 of my app (working no problem)
2) I place ver 2 on the server. the app retrieves ver2 and saves to SD card and prompts user to install the new package ver2
3) ver2 installs and works as expected
4) Problem is, every time the app starts it wants the user to re-install version 2 again.

So I was thinking the solution was simply delete the APK on the sdcard, but them the Async task wil simply retrieve ver2 again for the server.

So the only way to stop in from trying to install the v2 apk again is to remove from sdcard and from remote server.

As you can imagine that is not really going to work since I will never know when all users have received the lastest version.

Any help solving this is greatly appreciated.

I IMPLEMENTED THE "ldmuniz" method listed above.

NEW EDIT: Was just thinking all me APK's are named the same. Should I be naming the myapk_v1.0xx.apk and and in that version proactivily set the remote path to look for v.2.0 whenever it is released?

I tested the theory and it does SOLVE the issue. You need to name your APK file file some sort of versioning, remembering to always set your NEXT release version # in your currently released app. Not ideal but functional.

I received this error when I had a config file with <?php on the second line instead of the first.

Sometimes you need to reset ADB. To do that, in Eclipse, go:

Window>> Show View >> Android (Might be found in the "Other" option)>>Devices

in the device Tab, click the down arrow, and choose reset adb.

If you work with SpringBoot you can add specifying the environmental variable in the following property:

was.app.config.properties.toSystemProperties

Actually, you only need to use the default argument to add_argument as in this test.py script:

import argparse

if __name__ == '__main__':

    parser = argparse.ArgumentParser()
    parser.add_argument('--example', default=1)
    args = parser.parse_args()
    print(args.example)

test.py --example
% 1
test.py --example 2
% 2

How do I rename a specific column in pandas?

From v0.24+, to rename one (or more) columns at a time,

• DataFrame.rename() with axis=1 or axis='columns' (the axis argument was introduced in v0.21.

• Index.str.replace() for string/regex based replacement.

If you need to rename ALL columns at once,

• DataFrame.set_axis() method with axis=1. Pass a list-like sequence. Options are available for in-place modification as well.

rename with axis=1

df = pd.DataFrame('x', columns=['y', 'gdp', 'cap'], index=range(5))
df

   y gdp cap
0  x   x   x
1  x   x   x
2  x   x   x
3  x   x   x
4  x   x   x

With 0.21+, you can now specify an axis parameter with rename:

df.rename({'gdp':'log(gdp)'}, axis=1)
# df.rename({'gdp':'log(gdp)'}, axis='columns')
    
   y log(gdp) cap
0  x        x   x
1  x        x   x
2  x        x   x
3  x        x   x
4  x        x   x

(Note that rename is not in-place by default, so you will need to assign the result back.)

This addition has been made to improve consistency with the rest of the API. The new axis argument is analogous to the columns parameter—they do the same thing.

df.rename(columns={'gdp': 'log(gdp)'})

   y log(gdp) cap
0  x        x   x
1  x        x   x
2  x        x   x
3  x        x   x
4  x        x   x

rename also accepts a callback that is called once for each column.

df.rename(lambda x: x[0], axis=1)
# df.rename(lambda x: x[0], axis='columns')

   y  g  c
0  x  x  x
1  x  x  x
2  x  x  x
3  x  x  x
4  x  x  x

For this specific scenario, you would want to use

df.rename(lambda x: 'log(gdp)' if x == 'gdp' else x, axis=1)

Index.str.replace

Similar to replace method of strings in python, pandas Index and Series (object dtype only) define a ("vectorized") str.replace method for string and regex-based replacement.

df.columns = df.columns.str.replace('gdp', 'log(gdp)')
df
 
   y log(gdp) cap
0  x        x   x
1  x        x   x
2  x        x   x
3  x        x   x
4  x        x   x

The advantage of this over the other methods is that str.replace supports regex (enabled by default). See the docs for more information.

Passing a list to set_axis with axis=1

Call set_axis with a list of header(s). The list must be equal in length to the columns/index size. set_axis mutates the original DataFrame by default, but you can specify inplace=False to return a modified copy.

df.set_axis(['cap', 'log(gdp)', 'y'], axis=1, inplace=False)
# df.set_axis(['cap', 'log(gdp)', 'y'], axis='columns', inplace=False)

  cap log(gdp)  y
0   x        x  x
1   x        x  x
2   x        x  x
3   x        x  x
4   x        x  x

Note: In future releases, inplace will default to True.

Method Chaining
Why choose set_axis when we already have an efficient way of assigning columns with df.columns = ...? As shown by Ted Petrou in this answer set_axis is useful when trying to chain methods.

Compare

# new for pandas 0.21+
df.some_method1()
  .some_method2()
  .set_axis()
  .some_method3()

Versus

# old way
df1 = df.some_method1()
        .some_method2()
df1.columns = columns
df1.some_method3()

The former is more natural and free flowing syntax.

Put this in a file and make it executable:

#!/bin/bash
start=`grep -n $1 < $3 | head -n1 | cut -d: -f1; exit ${PIPESTATUS[0]}`
if [ ${PIPESTATUS[0]} -ne 0 ]; then
    echo "couldn't find start pattern!" 1>&2
    exit 1
fi
stop=`tail -n +$start < $3 | grep -n $2 | head -n1 | cut -d: -f1; exit ${PIPESTATUS[1]}`
if [ ${PIPESTATUS[0]} -ne 0 ]; then
    echo "couldn't find end pattern!" 1>&2
    exit 1
fi

stop=$(( $stop + $start - 1))

sed "$start,$stop!d" < $3

Execute the file with arguments (NOTE that the script does not handle spaces in arguments!):

1. Starting grep pattern
2. Stopping grep pattern
3. File path

To use with your example, use arguments: 1234 5555 myfile.txt

Includes lines with starting and stopping pattern.

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

 <script type="text/javascript">

  function omtCallFromAjax(urlVariable)
{ 
    alert("omt:"+urlVariable);
     $("#omtDiv").load("omtt.php?"+urlVariable);
}

 </script>

try this it work for me

I think it is better to update your "mysql-connector" lib package, so database can be still more safe.

I am using mysql of version 8.0.12. When I updated the mysql-connector-java to version 8.0.11, the problem was gone.

Use contains:

var yourItem:YourType!
if contains(yourArray, item){
    yourItem = item
}

Or you could try what Martin pointed you at, in the comments and give filter another try: Find Object with Property in Array.

Better to use android.R.drawable because it is public and documented.

You want to create an alias by simply typing:

c:\>alias kgs kubectl get svc

Created alias for kgs=kubectl get svc

And use the alias as follows:

c:\>kgs alfresco-svc

NAME           TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)   AGE
alfresco-svc   ClusterIP   10.7.249.219   <none>        80/TCP    8d

Just add the following alias.bat file to you path. It simply creates additional batch files in the same directory as itself.

  @echo off
  echo.
  for /f "tokens=1,* delims= " %%a in ("%*") do set ALL_BUT_FIRST=%%b
  echo @echo off > C:\Development\alias-script\%1.bat
  echo echo. >> C:\Development\alias-script\%1.bat
  echo %ALL_BUT_FIRST% %%* >> C:\Development\alias-script\%1.bat
  echo Created alias for %1=%ALL_BUT_FIRST%

An example of the batch file this created called kgs.bat is:

@echo off 
echo. 
kubectl get svc %* 

So I discovered pcregrep which stands for Perl Compatible Regular Expressions GREP.

For example, you need to find files where the '_name' variable is immediatelly followed by the '_description' variable:

find . -iname '*.py' | xargs pcregrep -M '_name.*\n.*_description'

Tip: you need to include the line break character in your pattern. Depending on your platform, it could be '\n', \r', '\r\n', ...

You can't rewrite a line without rewriting the entire file (unless the lines happen to be the same length). If your files are small then reading the entire target file into memory and then writing it out again might make sense. You can do that like this:

using System;
using System.IO;

class Program
{
    static void Main(string[] args)
    {
        int line_to_edit = 2; // Warning: 1-based indexing!
        string sourceFile = "source.txt";
        string destinationFile = "target.txt";

        // Read the appropriate line from the file.
        string lineToWrite = null;
        using (StreamReader reader = new StreamReader(sourceFile))
        {
            for (int i = 1; i <= line_to_edit; ++i)
                lineToWrite = reader.ReadLine();
        }

        if (lineToWrite == null)
            throw new InvalidDataException("Line does not exist in " + sourceFile);

        // Read the old file.
        string[] lines = File.ReadAllLines(destinationFile);

        // Write the new file over the old file.
        using (StreamWriter writer = new StreamWriter(destinationFile))
        {
            for (int currentLine = 1; currentLine <= lines.Length; ++currentLine)
            {
                if (currentLine == line_to_edit)
                {
                    writer.WriteLine(lineToWrite);
                }
                else
                {
                    writer.WriteLine(lines[currentLine - 1]);
                }
            }
        }
    }
}

If your files are large it would be better to create a new file so that you can read streaming from one file while you write to the other. This means that you don't need to have the whole file in memory at once. You can do that like this:

using System;
using System.IO;

class Program
{
    static void Main(string[] args)
    {
        int line_to_edit = 2;
        string sourceFile = "source.txt";
        string destinationFile = "target.txt";
        string tempFile = "target2.txt";

        // Read the appropriate line from the file.
        string lineToWrite = null;
        using (StreamReader reader = new StreamReader(sourceFile))
        {
            for (int i = 1; i <= line_to_edit; ++i)
                lineToWrite = reader.ReadLine();
        }

        if (lineToWrite == null)
            throw new InvalidDataException("Line does not exist in " + sourceFile);

        // Read from the target file and write to a new file.
        int line_number = 1;
        string line = null;
        using (StreamReader reader = new StreamReader(destinationFile))
        using (StreamWriter writer = new StreamWriter(tempFile))
        {
            while ((line = reader.ReadLine()) != null)
            {
                if (line_number == line_to_edit)
                {
                    writer.WriteLine(lineToWrite);
                }
                else
                {
                    writer.WriteLine(line);
                }
                line_number++;
            }
        }

        // TODO: Delete the old file and replace it with the new file here.
    }
}

You can afterwards move the file once you are sure that the write operation has succeeded (no excecption was thrown and the writer is closed).

Note that in both cases it is a bit confusing that you are using 1-based indexing for your line numbers. It might make more sense in your code to use 0-based indexing. You can have 1-based index in your user interface to your program if you wish, but convert it to a 0-indexed before sending it further.

Also, a disadvantage of directly overwriting the old file with the new file is that if it fails halfway through then you might permanently lose whatever data wasn't written. By writing to a third file first you only delete the original data after you are sure that you have another (corrected) copy of it, so you can recover the data if the computer crashes halfway through.

A final remark: I noticed that your files had an xml extension. You might want to consider if it makes more sense for you to use an XML parser to modify the contents of the files instead of replacing specific lines.

Look at the Default.aspx/Default.aspx.cs and the Global.asax.cs

You can set up a default route:

        routes.MapRoute(
            "Default", // Route name
            "",        // URL with parameters
            new { controller = "Home", action = "Index"}  // Parameter defaults
        );

Just change the Controller/Action names to your desired default. That should be the last route in the Routing Table.

Mine showed up in VS2010 after writing the first parenthesis..

so, prams.Add(

After doings something like that, the box with the up and down arrows appeared.

it works for me. if you want to enable future time for choose, you have to delete maximum date. You need to to do like followings.

 btnDate.setOnClickListener(new View.OnClickListener() {
                       @Override
                       public void onClick(View v) {
                              DialogFragment newFragment = new DatePickerFragment();
                                    newFragment.show(getSupportFragmentManager(), "datePicker");
                            }
                        });

            public static class DatePickerFragment extends DialogFragment
                        implements DatePickerDialog.OnDateSetListener {

                    @Override
                    public Dialog onCreateDialog(Bundle savedInstanceState) {
                        final Calendar c = Calendar.getInstance();
                        int year = c.get(Calendar.YEAR);
                        int month = c.get(Calendar.MONTH);
                        int day = c.get(Calendar.DAY_OF_MONTH);
                        DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, year, month, day);
                        dialog.getDatePicker().setMaxDate(c.getTimeInMillis());
                        return  dialog;
                    }

                    public void onDateSet(DatePicker view, int year, int month, int day) {
                       btnDate.setText(ConverterDate.ConvertDate(year, month + 1, day));
                    }
                }

This should work for you. Tested all the way back to SQL 2000.

create table #user (username varchar(25))

insert into #user (username) values ('Paul')
insert into #user (username) values ('John')
insert into #user (username) values ('Mary')

declare @tmp varchar(250)
SET @tmp = ''
select @tmp = @tmp + username + ', ' from #user

select SUBSTRING(@tmp, 0, LEN(@tmp))

A default constructor is a constructor that either has no parameters, or if it has parameters, all the parameters have default values.

In MySQL:

SELECT  *
FROM    mytable
WHERE   record_date >= NOW() - INTERVAL 1 DAY

In SQL Server:

SELECT  *
FROM    mytable
WHERE   record_date >= DATEADD(day, -1, GETDATE())

In Oracle:

SELECT  *
FROM    mytable
WHERE   record_date >= SYSDATE - 1

In PostgreSQL:

SELECT  *
FROM    mytable
WHERE   record_date >= NOW() - '1 day'::INTERVAL

In Redshift:

SELECT  *
FROM    mytable
WHERE   record_date >= GETDATE() - '1 day'::INTERVAL

In SQLite:

SELECT  *
FROM    mytable
WHERE   record_date >= datetime('now','-1 day')

In MS Access:

SELECT  *
FROM    mytable
WHERE   record_date >= (Now - 1)

You can't clone it, and how you are going to solve your problem depends on what the source of the data is.

One solution is to read all data from the InputStream into a byte array, and then create a ByteArrayInputStream around that byte array, and pass that input stream into your method.

Edit 1: That is, if the other method also needs to read the same data. I.e you want to "reset" the stream.

#include <sstream>
#include <string>

std::stringstream ss;
ss << "Hello, world, " << myInt << niceToSeeYouString;
std::string s = ss.str();

Take a look at this Guru Of The Week article from Herb Sutter: The String Formatters of Manor Farm

Localization support in legacy browsers is poor. Originally, this was due to phrases in the ECMAScript language spec that look like this:

Number.prototype.toLocaleString()
Produces a string value that represents the value of the Number formatted according to the conventions of the host environment’s current locale. This function is implementation-dependent, and it is permissible, but not encouraged, for it to return the same thing as toString.

Every localization method defined in the spec is defined as "implementation-dependent", which results in a lot of inconsistencies. In this instance, Chrome Opera and Safari would return the same thing as .toString(). Firefox and IE will return locale formatted strings, and IE even includes a thousand separator (perfect for currency strings). Chrome was recently updated to return a thousands-separated string, though with no fixed decimal.

For modern environments, the ECMAScript Internationalization API spec, a new standard that complements the ECMAScript Language spec, provides much better support for string comparison, number formatting, and the date and time formatting; it also fixes the corresponding functions in the Language Spec. An introduction can be found here. Implementations are available in:

• Chrome 24
• Firefox 29
• Internet Explorer 11
• Opera 15

There is also a compatibility implementation, Intl.js, which will provide the API in environments where it doesn't already exist.

Determining the user's preferred language remains a problem since there's no specification for obtaining the current language. Each browser implements a method to obtain a language string, but this could be based on the user's operating system language or just the language of the browser:

// navigator.userLanguage for IE, navigator.language for others
var lang = navigator.language || navigator.userLanguage;

A good workaround for this is to dump the Accept-Language header from the server to the client. If formatted as a JavaScript, it can be passed to the Internationalization API constructors, which will automatically pick the best (or first-supported) locale.

In short, you have to put in a lot of the work yourself, or use a framework/library, because you cannot rely on the browser to do it for you.

Various libraries and plugins for localization:

• Mantained by an open community (no order):

• Polyglot.js - AirBnb's internationalization library
• Intl.js - a compatibility implementation of the Internationalisation API
• i18next (home) for i18n (incl. jquery plugin, translation ui,...)
• moment.js (home) for dates
• numbro.js (home) (was numeral.js (home)) for numbers and currency
• l10n.js (home)
• L10ns (home) tool for i18n workflow and complex string formatting
• jQuery Localisation (plugin) (home)
• YUI Internationalization support
• jquery.i18Now for dates
• browser-i18n with support to pluralization
• counterpart is inspired by Ruby's famous I18n gem
• jQuery Globalize jQuery's own i18n library
• js-lingui - MessageFormat implementation for JS (ES2016) and React

• Others:

• jQuery Globalization (plugin)
• requirejs-i18n Define an I18N Bundle with RequireJS.

The FileInputStream class works directly with the underlying file system. If the file in question is not physically present there, it will fail to open it. The getResourceAsStream() method works differently. It tries to locate and load the resource using the ClassLoader of the class it is called on. This enables it to find, for example, resources embedded into jar files.

If you are getting a timeout while on the table designer, change the "Transaction time-out after" value under Tools --> Options --> Designers --> Table and Database Designers

This will get rid of this message: "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."

Using a null reference as the first operand to instanceof returns false.

You can't delete objects, they are removed when there are no more references to them. You can delete references with delete.

However, if you have created circular references in your objects you may have to de-couple some things.

You can use debug: false,

Example: //mysql connection

var dbcon1 = mysql.createConnection({
      host: "localhost",
      user: "root",
      password: "",
      database: "node5",
      debug: false,
    });

if you use the gmap V3 plugin: $("#map").gmap("removeAllMarkers");

see: http://www.smashinglabs.pl/gmap/documentation#after-load

See "Can I Use" for the full list of IE11 Flexbox bugs and more

There are numerous Flexbox bugs in IE11 and other browsers - see flexbox on Can I Use -> Known Issues, where the following are listed under IE11:

• IE 11 requires a unit to be added to the third argument, the flex-basis property
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property
• IE 11 does not vertically align items correctly when min-height is used

Also see Philip Walton's Flexbugs list of issues and workarounds.

You can use IList(Of String) in the function :

Private Function getWriteBits() As IList(Of String)


Dim temp1 As String
Dim temp2 As Boolean
Dim temp3 As Boolean


'Pallet Destination Unique
Dim temp4 As Boolean
Dim temp5 As Boolean
Dim temp6 As Boolean

Dim lstWriteBits As Ilist = {temp1, temp2, temp3, temp4, temp5, temp6}

Return lstWriteBits
End Function

use list1.AddRange(list2) to add lists

• If navigationBarHidden = true, the child UIViewController's preferredStatusBarX are called, since the child is displaying the content under the status bar.
• If navigationBarHidden = false, the UINavigationController's preferredStatusBarX are called, after all it is displaying the content under the status bar.
• The UINavigationController's default preferredStatusBarStyle uses the value from UINav.navigationBar.barStyle. .Default = black status bar content, .Black = white status bar content.
• So if you're setting barTintColor to some custom colour (which you likely are), you also need to set barStyle to .Black to get white status bar content. I'd set barStyle to black before setting barTintColor, in case barStyle overrides the barTintColor.
• An alternative is that you can subclass UINavigationController rather than mucking around with bar style.
• HOWEVER, if you subclass UINavigationController, you get no control over the status bar if navigationBarHidden = true. Somehow UIKit goes direct to the child UIViewController without asking the UINavigationController in this situation. I would have thought it should be the UINavigationController's responsibility to ask the child >shrugs<.
• And modally displayed UIViewController's only get a say in the status bar if modalPresentationStyle = .FullScreen.
• If you've got a custom presentation style modal view controller and you really want it to control the status bar, you can set modalPresentationCapturesStatusBarAppearance = true.

         File file = ...
         byte[] data = ...
         try{
            FileOutputStream fos = FileOutputStream(file);
            fos.write(data);
            fos.flush();
            fos.close();
         }catch(Exception e){
          }

but if the bytes array length is more than 1024 you should use loop to write the data.

If you want to pause the program to take screenshots of the progress

(shown in let's say cv2.imshow)

cv2.waitKey(0) would continue after pressing "Scr" button (or its combination), but you can try this

cv2.waitKey(0)
input('')

cv2.waitkey(0) to give the program enough time to process everything you want to see in the imshow and input('')

to make it wait for you to press Enter in the console window

this works on python 3

Question: How can I open the href in the new window or tab with jQuery?

var url = $(this).attr('href').attr('target','_blank');

I am working on DOM Keyboard Event Level 3 polyfill . In latest browsers or with this polyfill you can do something like this:

element.addEventListener("keydown", function(e){ console.log(e.key, e.char, e.keyCode) })

var e = new KeyboardEvent("keydown", {bubbles : true, cancelable : true, key : "Q", char : "Q", shiftKey : true});
element.dispatchEvent(e);

//If you need legacy property "keyCode"
// Note: In some browsers you can't overwrite "keyCode" property. (At least in Safari)
delete e.keyCode;
Object.defineProperty(e, "keyCode", {"value" : 666})

UPDATE:

Now my polyfill supports legacy properties "keyCode", "charCode" and "which"

var e = new KeyboardEvent("keydown", {
    bubbles : true,
    cancelable : true,
    char : "Q",
    key : "q",
    shiftKey : true,
    keyCode : 81
});

Examples here

Additionally here is cross-browser initKeyboardEvent separately from my polyfill: (gist)

Polyfill demo

Use NSJSONSerialization:

NSDictionary *dict;
NSData *dataFromDict = [NSJSONSerialization dataWithJSONObject:dict
                                                       options:NSJSONWritingPrettyPrinted
                                                         error:&error];

NSDictionary *dictFromData = [NSJSONSerialization JSONObjectWithData:dataFromDict
                                                             options:NSJSONReadingAllowFragments
                                                               error:&error];

The latest returns id, so its a good idea to check the returned object type after you cast (here i casted to NSDictionary).

String newline = System.getProperty("line.separator");
System.out.println("First line" + newline);
System.out.println("Second line" + newline);
System.out.println("Third line");

Swift 4:

It depends by the encoding rules followed by your server.

Apple offer this class method, but it don't report wich kind of RCF protocol it follows.

var escapedString = originalString.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)!

Following this useful tool you should guarantee the encoding of these chars for your parameters:

• $ (Dollar Sign) becomes %24
• & (Ampersand) becomes %26
• + (Plus) becomes %2B
• , (Comma) becomes %2C
• : (Colon) becomes %3A
• ; (Semi-Colon) becomes %3B
• = (Equals) becomes %3D
• ? (Question Mark) becomes %3F
• @ (Commercial A / At) becomes %40

In other words, speaking about URL encoding, you should following the RFC 1738 protocol.

And Swift don't cover the encoding of the + char for example, but it works well with these three @ : ? chars.

So, to correctly encoding each your parameter , the .urlHostAllowed option is not enough, you should add also the special chars as for example:

encodedParameter = parameter.replacingOccurrences(of: "+", with: "%2B")

Hope this helps someone who become crazy to search these informations.

Change the active scheme Device from Simulator to Generic iOS Device

I create a block to reset all my sequences:

DECLARE
    I_val number;
BEGIN
    FOR US IN
        (SELECT US.SEQUENCE_NAME FROM USER_SEQUENCES US)
    LOOP
        execute immediate 'select ' || US.SEQUENCE_NAME || '.nextval from dual' INTO l_val;
        execute immediate 'alter sequence ' || US.SEQUENCE_NAME || ' increment by -' || l_val || ' minvalue 0';
        execute immediate 'select ' || US.SEQUENCE_NAME || '.nextval from dual' INTO l_val;
        execute immediate 'alter sequence ' || US.SEQUENCE_NAME || ' increment by 1 minvalue 0';
    END LOOP;
END;

In the simplest case, just do

X <- read.csv(url("http://some.where.net/data/foo.csv"))

plus which ever options read.csv() may need.

Edit in Sep 2020 or 9 years later:

For a few years now R also supports directly passing the URL to read.csv:

X <- read.csv("http://some.where.net/data/foo.csv")

Long answer: Yes this can be done and many packages have use that feature for years. E.g. the tseries packages uses exactly this feature to download stock prices from Yahoo! for almost a decade:

R> library(tseries)
Loading required package: quadprog
Loading required package: zoo

    ‘tseries’ version: 0.10-24

    ‘tseries’ is a package for time series analysis and computational finance.

    See ‘library(help="tseries")’ for details.

The :before pseudo element isn't needed for the clearfix hack itself.

It's just an additional nice feature helping to prevent margin-collapsing of the first child element. Thus the top margin of an child block element of the "clearfixed" element is guaranteed to be positioned below the top border of the clearfixed element.

display:table is being used because display:block doesn't do the trick. Using display:block margins will collapse even with a :before element.

There is one caveat: if vertical-align:baseline is used in table cells with clearfixed <div> elements, Firefox won't align well. Then you might prefer using display:block despite loosing the anti-collapsing feature. In case of further interest read this article: Clearfix interfering with vertical-align.

There is a great checklist found on Github:

Authentication

• Don't reinvent the wheel in Authentication, token generation, password storage. Use the standards.

• Use Max Retry and jail features in Login.

• Use encryption on all sensitive data.

JWT (JSON Web Token)

• Use a random complicated key (JWT Secret) to make brute forcing the token very hard.

• Don't extract the algorithm from the payload. Force the algorithm in the backend (HS256 or RS256).

• Make token expiration (TTL, RTTL) as short as possible.

• Don't store sensitive data in the JWT payload, it can be decoded easily.

OAuth

• Always validate redirect_uri server-side to allow only whitelisted URLs.

• Always try to exchange for code and not tokens (don't allow response_type=token).

• Use state parameter with a random hash to prevent CSRF on the OAuth authentication process.

• Define the default scope, and validate scope parameters for each application.

Access

• Limit requests (Throttling) to avoid DDoS / brute-force attacks.

• Use HTTPS on server side to avoid MITM (Man In The Middle Attack)

• Use HSTS header with SSL to avoid SSL Strip attack.

Input

• Use the proper HTTP method according to the operation: GET (read), POST (create), PUT/PATCH (replace/update), and DELETE (to delete a record), and respond with 405 Method Not Allowed if the requested method isn't appropriate for the requested resource.

• Validate content-type on request Accept header (Content Negotiation) to allow only your supported format (e.g. application/xml, application/json, etc) and respond with 406 Not Acceptable response if not matched.

• Validate content-type of posted data as you accept (e.g. application/x-www-form-urlencoded, multipart/form-data, application/json, etc).

• Validate User input to avoid common vulnerabilities (e.g. XSS, SQL-Injection, Remote Code Execution, etc).

• Don't use any sensitive data (credentials, Passwords, security tokens, or API keys) in the URL, but use standard Authorization header.

• Use an API Gateway service to enable caching, Rate Limit policies (e.g. Quota, Spike Arrest, Concurrent Rate Limit) and deploy APIs resources dynamically.

Processing

• Check if all the endpoints are protected behind authentication to avoid broken authentication process.

• User own resource ID should be avoided. Use /me/orders instead of /user/654321/orders.

• Don't auto-increment IDs. Use UUID instead.

• If you are parsing XML files, make sure entity parsing is not enabled to avoid XXE (XML external entity attack).

• If you are parsing XML files, make sure entity expansion is not enabled to avoid Billion Laughs/XML bomb via exponential entity expansion attack.

• Use a CDN for file uploads.

• If you are dealing with huge amount of data, use Workers and Queues to process as much as possible in background and return response fast to avoid HTTP Blocking.

• Do not forget to turn the DEBUG mode OFF.

Output

• Send X-Content-Type-Options: nosniff header.

• Send X-Frame-Options: deny header.

• Send Content-Security-Policy: default-src 'none' header.

• Remove fingerprinting headers - X-Powered-By, Server, X-AspNet-Version etc.

• Force content-type for your response, if you return application/json then your response content-type is application/json.

• Don't return sensitive data like credentials, Passwords, security tokens.

• Return the proper status code according to the operation completed. (e.g. 200 OK, 400 Bad Request, 401 Unauthorized, 405 Method Not Allowed, etc).

 for (int i=0;i<=dtB.Columns.Count-1;i++)
 {
   array(0, i) = dtB.Compute("SUM([" & dtB.Columns(i).ColumnName & "])", "")                   
 }

It took me a couple hours to figure this out but I finally got it to work using CNTLM and afterwards got it to work with just a pip config file. Here is how I got it work with the pip config file...

Solution:

1. In Windows navigate to your user profile directory (Ex. C:\Users\Sync) and create a folder named "pip"

2. Create a file named "pip.ini" in this directory (Ex. C:\Users\Sync\pip\pip.ini) and enter the following into it:

    [global]
    trusted-host = pypi.python.org
                   pypi.org
                   files.pythonhosted.org
    proxy = http://[domain name]%5C[username]:[password]@[proxy address]:[proxy port]

Replace [domain name], [username], [password], [proxy address] and [proxy port] with your own information.

Note, if your [domain name], [username] or [password] has special characters, you have to percent-encode | encode them.

3. At this point I was able to run "pip install" without any issues.

Hopefully this works for others too!

P.S.: This may pose a security concern because of having your password stored in plain text. If this is an issue, consider setting up CNTLM using this article (allows using hashed password instead of plain text). Afterwards set proxy = 127.0.0.1:3128in the "pip.ini" file mentioned above.

This question is not specific to jQuery, but specific to JavaScript in general. The core problem is how to "channel" a variable in embedded functions. This is the example:

var abc = 1; // we want to use this variable in embedded functions

function xyz(){
  console.log(abc); // it is available here!
  function qwe(){
    console.log(abc); // it is available here too!
  }
  ...
};

This technique relies on using a closure. But it doesn't work with this because this is a pseudo variable that may change from scope to scope dynamically:

// we want to use "this" variable in embedded functions

function xyz(){
  // "this" is different here!
  console.log(this); // not what we wanted!
  function qwe(){
    // "this" is different here too!
    console.log(this); // not what we wanted!
  }
  ...
};

What can we do? Assign it to some variable and use it through the alias:

var abc = this; // we want to use this variable in embedded functions

function xyz(){
  // "this" is different here! --- but we don't care!
  console.log(abc); // now it is the right object!
  function qwe(){
    // "this" is different here too! --- but we don't care!
    console.log(abc); // it is the right object here too!
  }
  ...
};

this is not unique in this respect: arguments is the other pseudo variable that should be treated the same way — by aliasing.

The time problem has to do with the ID3 headers of the MP3 files, which is something your method isn't taking into account as the entire file is copied.

Do you have a language of choice that you want to use or doesn't it matter? That will affect what libraries are available that support the operations you want.

Introduction

The ServletContext#getRealPath() is intented to convert a web content path (the path in the expanded WAR folder structure on the server's disk file system) to an absolute disk file system path.

The "/" represents the web content root. I.e. it represents the web folder as in the below project structure:

YourWebProject
 |-- src
 |    :
 |
 |-- web
 |    |-- META-INF
 |    |    `-- MANIFEST.MF
 |    |-- WEB-INF
 |    |    `-- web.xml
 |    |-- index.jsp
 |    `-- login.jsp
 :    

So, passing the "/" to getRealPath() would return you the absolute disk file system path of the /web folder of the expanded WAR file of the project. Something like /path/to/server/work/folder/some.war/ which you should be able to further use in File or FileInputStream.

Note that most starters don't seem to see/realize that you can actually pass the whole web content path to it and that they often use

String absolutePathToIndexJSP = servletContext.getRealPath("/") + "index.jsp"; // Wrong!

or even

String absolutePathToIndexJSP = servletContext.getRealPath("") + "index.jsp"; // Wronger!

instead of

String absolutePathToIndexJSP = servletContext.getRealPath("/index.jsp"); // Right!

Don't ever write files in there

Also note that even though you can write new files into it using FileOutputStream, all changes (e.g. new files or edited files) will get lost whenever the WAR is redeployed; with the simple reason that all those changes are not contained in the original WAR file. So all starters who are attempting to save uploaded files in there are doing it wrong.

Moreover, getRealPath() will always return null or a completely unexpected path when the server isn't configured to expand the WAR file into the disk file system, but instead into e.g. memory as a virtual file system.

getRealPath() is unportable; you'd better never use it

Use getRealPath() carefully. There are actually no sensible real world use cases for it. Based on my 20 years of Java EE experience, there has always been another way which is much better and more portable than getRealPath().

If all you actually need is to get an InputStream of the web resource, better use ServletContext#getResourceAsStream() instead, this will work regardless of the way how the WAR is expanded. So, if you for example want an InputStream of index.jsp, then do not do:

InputStream input = new FileInputStream(servletContext.getRealPath("/index.jsp")); // Wrong!

But instead do:

InputStream input = servletContext.getResourceAsStream("/index.jsp"); // Right!

Or if you intend to obtain a list of all available web resource paths, use ServletContext#getResourcePaths() instead.

Set<String> resourcePaths = servletContext.getResourcePaths("/");

You can obtain an individual resource as URL via ServletContext#getResource(). This will return null when the resource does not exist.

URL resource = servletContext.getResource(path);

Or if you intend to save an uploaded file, or create a temporary file, then see the below "See also" links.

See also:

• getResourceAsStream() vs FileInputStream
• Recommended way to save uploaded files in a servlet application
• Simple ways to keep data on redeployment of Java EE 7 web application

You can write your select query as,

select * from table_name where to_char(date_time_column, 'YYYY-MM')  = '2011-03';

MacPorts is another package manager for OS X:.

Installation instructions are at The MacPorts Project -- Download & Installation after which one issues sudo port install pythonXX, where XX is 27 or 35.

I know this is old, but I've created a directive for this purpose in case anyone is looking for an easy solution. Very simple to use.

redirected uri is the location where the user will be redirected after successfully login to your app. for example to get access token for your app in facebook you need to subimt redirected uri which is nothing only the app Domain that your provide when you create your facebook app.

<div class="d-flex justify-content-center align-items-center container ">

    <div class="row ">


        <form action="">
            <div class="form-group">
                <label for="inputUserName" class="control-label">Enter UserName</label>

                <small id="emailnotification" class="form-text text-muted">Enter Valid Email Id</small>

Say you have an array like this:

$array = (0=>'123',1=>'abc','test'=>'hi there!')

In your foreach loop, each loop would be:

$key = 0, $value = '123'
$key = 1, $value = 'abc'
$key = 'test', $value = 'hi there!'

It's great for those times when you need to know the array key.

$('body').bind('beforeunload',function(){
   //do something
});

But this wont save any info for later, unless you were planning on saving that in a cookie somewhere (or local storage) and the unload event does not always fire in all browsers.

Example: http://jsfiddle.net/maniator/qpK7Y/

Code:

$(window).bind('beforeunload',function(){

     //save info somewhere

    return 'are you sure you want to leave?';

});

Put the number you want to multiply by in a cell that is not in your range. Select the cell and "Copy" it to the clipboard. Next, select the Range A1:D5, and from the menu choose Edit|Paste Special. A dialog box will appear. In the "Operation" area, select "Multiply" and click "OK".

@Jon: Jon, are you saying using multiple where clauses e.g.

var query = from r in tempData.AsEnumerable()
            where r.Field<string>("UserName") != "XXXX" 
            where r.Field<string>("UserName") != "YYYY"
            select r;

is more restictive than using

var query = from r in tempData.AsEnumerable()
            where r.Field<string>("UserName") != "XXXX" && r.Field<string>("UserName") != "YYYY"
            select r;

I think they are equivalent as far as the result goes.

However, I haven't tested, if using multiple where in the first example cause in 2 subqueries, i.e. .Where(r=>r.UserName!="XXXX").Where(r=>r.UserName!="YYYY) or the LINQ translator is smart enought to execute .Where(r=>r.UserName!="XXXX" && r.UsernName!="YYYY")

sh files are unix (linux) shell executables files, they are the equivalent (but much more powerful) of bat files on windows.

So you need to run it from a linux console, just typing its name the same you do with bat files on windows.

Daniel A. White Solution works great for classes.

I've got a situation where I had to find input fields like donee_1_card where 1 is an index.

My solution has been

$("input[name^='donee']" && "input[name*='card']")

Though I am not sure how optimal it is.

assertTrue will fail if the second parameter evaluates to false (in other words, it ensures that the value is true). assertFalse does the opposite.

assertTrue("This will succeed.", true);
assertTrue("This will fail!", false);

assertFalse("This will succeed.", false);
assertFalse("This will fail!", true);

As with many other things, the best way to become familiar with these methods is to just experiment :-).

I had this error when trying to SSH into my Raspberry pi from my MBP via bash terminal. My RPI was connected to the network via wifi/wlan0 and this IP had been changed upon restart by my routers DHCP.

Check IP being used to login via SSH is correct. Re-check IP of device being SSH'd into (in my case the RPI), which can be checked using hostname -I

Confirm/amend SSH login credentials on "guest" device (in my case the MBP) and it worked fine in my attempt.

If you want the dot or other characters with a special meaning in regexes to be a normal character, you have to escape it with a backslash. Since regexes in Java are normal Java strings, you need to escape the backslash itself, so you need two backslashes e.g. \\.

After looking for an answer for myself for some time, i could find something. in general if we are using it for just one property it appears same even if we do a "View Source" of generated HTML Below is generated HTML for example, when i want to display only Name property for my class

    <td>
    myClassNameProperty
    </td>
   <td>
    myClassNameProperty, This is direct from Item
    </td>

This is the generated HTML from below code

<td>
@Html.DisplayFor(modelItem=>item.Genre.Name)            
</td>

<td>
@item.Genre.Name, This is direct from Item
</td>

At the same time now if i want to display all properties in one statement for my class "Genre" in this case, i can use @Html.DisplayFor() to save on my typing, for least

i can write @Html.DisplayFor(modelItem=>item.Genre) in place of writing a separate statement for each property of Genre as below

@item.Genre.Name
@item.Genre.Id
@item.Genre.Description

and so on depending on number of properties.

just use this as a middleware

<?php

namespace App\Http\Middleware;

use Closure;

class CorsMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $response = $next($request);
        $response->header('Access-Control-Allow-Origin', '*');
        $response->header('Access-Control-Allow-Methods', '*');

        return $response;
    }
}

and register the middleware in your kernel file on this path app/Http/Kernel.php in which group that you prefer and everything will be fine

    String str = "1,2,3,4,5,6,7,8,9,0";
    String items[] = str.split(",");
    int ent[] = new int[items.length];
    for(i=0;i<items.length;i++){
        try{
            ent[i] = Integer.parseInt(items[i]);
            System.out.println("#"+i+": "+ent[i]);//Para probar
        }catch(NumberFormatException e){
            //Error
        }
    }

function relativepath($to){
    $a=explode("/",$_SERVER["PHP_SELF"] );
    $index= array_search("$to",$a);
    $str=""; 
    for ($i = 0; $i < count($a)-$index-2; $i++) {
        $str.= "../";
    }
    return $str;
    }

Here is the best solution i made about that, you just need to specify at which level you want to stop, but the problem is that you have to use this folder name one time.

My (simplified) technical reason is that static methods are not in the vtable, and the call site is chosen at compile time. It's the same reason you can't have override or virtual static members. For more details, you'd need a CS grad or compiler wonk - of which I'm neither.

For the political reason, I'll quote Eric Lippert (who is a compiler wonk, and holds a Bachelor of Mathematics, Computer science and Applied Mathematics from University of Waterloo (source: LinkedIn):

...the core design principle of static methods, the principle that gives them their name...[is]...it can always be determined exactly, at compile time, what method will be called. That is, the method can be resolved solely by static analysis of the code.

Note that Lippert does leave room for a so-called type method:

That is, a method associated with a type (like a static), which does not take a non-nullable “this” argument (unlike an instance or virtual), but one where the method called would depend on the constructed type of T (unlike a static, which must be determinable at compile time).

but is yet to be convinced of its usefulness.

I had the same situation and I found a way around with a bit of engineering as follows - -

1. You have to have your method in parent class without any parameter and use - -

   Class<? extends Person> cl = this.getClass(); // inside parent class
   

2. Now, with 'cl' you can access all child class fields with their name and initialized values by using - -

   cl.getDeclaredFields(); cl.getField("myfield"); // and many more
   

3. In this situation your 'this' pointer will reference your child class object if you are calling parent method through your child class object.

4. Another thing you might need to use is Object obj = cl.newInstance();

Let me know if still you got stucked somewhere.

I have the same requirement. I just want to print a result object into JSON format so I use the code below. I hope you find something in it.

// Code of Conversion
$query = "SELECT * FROM products;";
$result = mysqli_query($conn , $query);

if ($result) {
echo "</br>"."Results Found";

// Conversion of result object into JSON format
$rows = array();
while($temp = mysqli_fetch_assoc($result)) {
    $rows[] = $temp;
}
echo "</br>" . json_encode($rows);

} else {
    echo "No Results Found";
}

Try this if you are using jquery version >=1.9,

var browser;
jQuery.uaMatch = function (ua) {
    ua = ua.toLowerCase();

    var match = /(chrome)[ \/]([\w.]+)/.exec(ua) ||
        /(webkit)[ \/]([\w.]+)/.exec(ua) ||
        /(opera)(?:.*version|)[ \/]([\w.]+)/.exec(ua) ||
        /(msie) ([\w.]+)/.exec(ua) || 
        ua.indexOf("compatible") < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec(ua) ||
       /(Trident)[\/]([\w.]+)/.exec(ua) || [];

    return {
        browser: match[1] || "",
        version: match[2] || "0"
    };
};
// Don't clobber any existing jQuery.browser in case it's different
if (!jQuery.browser) {
    matched = jQuery.uaMatch(navigator.userAgent);
    browser = {};

    if (matched.browser) {
        browser[matched.browser] = true;
        browser.version = matched.version;
    }

    // Chrome is Webkit, but Webkit is also Safari.
    if (browser.chrome) {
        browser.webkit = true;
    } else if (browser.webkit) {
        browser.safari = true;
    }

    jQuery.browser = browser;
}

If using jQuery version <1.9 ($.browser was removed in jQuery 1.9) use the following code instead:

$('.myClass').on('click', function (event) {
    if ($.browser.msie) {
        alert($.browser.version);
    }
});

Very simple, no library required:

var date = new Date();
var firstDay = new Date(date.getFullYear(), date.getMonth(), 1);
var lastDay = new Date(date.getFullYear(), date.getMonth() + 1, 0);

or you might prefer:

var date = new Date(), y = date.getFullYear(), m = date.getMonth();
var firstDay = new Date(y, m, 1);
var lastDay = new Date(y, m + 1, 0);

EDIT

Some browsers will treat two digit years as being in the 20th century, so that:

new Date(14, 0, 1);

gives 1 January, 1914. To avoid that, create a Date then set its values using setFullYear:

var date = new Date();
date.setFullYear(14, 0, 1); // 1 January, 14

For multicolumn listbox extract data from any column of selected row by

 listboxControl.List(listboxControl.ListIndex,col_num)

where col_num is required column ( 0 for first column)

Use the config method to change the value of the label:

top = Tk()

l = Label(top)
l.pack()

l.config(text = "Hello World", width = "50")

All of the answers above are very good but I cleaned it up a little bit.

This solution automatically puts the name of the submit button pressed into the action hidden field. Both the javascript on the page and the server code can check the action hidden field value as needed.

The solution uses jquery to automatically apply to all submit buttons.

<input type="hidden" name="action" id="action" />
<script language="javascript" type="text/javascript">
    $(document).ready(function () {
        //when a submit button is clicked, put its name into the action hidden field
        $(":submit").click(function () { $("#action").val(this.name); });
    });
</script>
<input type="submit" class="bttn" value="<< Back" name="back" />
<input type="submit" class="bttn" value="Finish" name="finish" />
<input type="submit" class="bttn" value="Save" name="save" />
<input type="submit" class="bttn" value="Next >>" name="next" />
<input type="submit" class="bttn" value="Delete" name="delete" />
<input type="button" class="bttn" name="cancel" value="Cancel" onclick="window.close();" />

Then write code like this into your form submit handler.

 if ($("#action").val() == "delete") {
     return confirm("Are you sure you want to delete the selected item?");
 }

Combining the previous answers provides these solutions:

if (typeof str == 'string' || str instanceof String)

or

Object.prototype.toString.call(str) == '[object String]'

The data.table package introduced the IDate class some time ago and zoo-package-like functions to retrieve months, days, etc (Check ?IDate). so, you can extract the desired info now in the following ways:

require(data.table)
df <- data.frame(id = 1:3,
                 date = c("2004-02-06" , "2006-03-14" , "2007-07-16"))
setDT(df)
df[ , date := as.IDate(date) ] # instead of as.Date()
df[ , yrmn := paste0(year(date), '-', month(date)) ]
df[ , yrmn2 := format(date, '%Y-%m') ]

I prefer to do it by using a BAT file.

With BAT file you have more control and can do whatever you want.

string batFileName = path + @"\" + Guid.NewGuid() + ".bat";

using (StreamWriter batFile = new StreamWriter(batFileName))
{
    batFile.WriteLine($"YOUR COMMAND");
    batFile.WriteLine($"YOUR COMMAND");
    batFile.WriteLine($"YOUR COMMAND");
}

ProcessStartInfo processStartInfo = new ProcessStartInfo("cmd.exe", "/c " + batFileName);
processStartInfo.UseShellExecute = true;
processStartInfo.CreateNoWindow = true;
processStartInfo.WindowStyle = ProcessWindowStyle.Normal;

Process p = new Process();
p.StartInfo = processStartInfo;
p.Start();
p.WaitForExit();

File.Delete(batFileName);

I have found that the following works well in 2.7.x

import os
two_up = os.path.normpath(os.path.join(__file__,'../'))

Will www.example.com be able to set cookie for .com?

No, but example.com.fr may be able to set a cookie for example2.com.fr. Firefox protects against this by maintaining a list of TLDs: http://securitylabs.websense.com/content/Blogs/3108.aspx

Apparently Internet Explorer doesn't allow two-letter domains to set cookies, which I suppose explains why o2.ie simply redirects to o2online.ie. I'd often wondered that.

You can use java8 + rxjava.

//import java.util.stream.IntStream;
//import rx.Observable;

    IntStream intStream  = IntStream.range(1,10000000);
    Observable.from(() -> intStream.iterator())
            .takeWhile(n -> n < 10)
            .forEach(n-> System.out.println(n));

Here's a simple wrapper for steven's answer. This function doesn't do repeated runs/averaging, just saves you from having to repeat the timing code everywhere :)

'''function which prints the wall time it takes to execute the given command'''
def time_func(func, *args): #*args can take 0 or more 
  import time
  start_time = time.time()
  func(*args)
  end_time = time.time()
  print("it took this long to run: {}".format(end_time-start_time))

Try this

I recently leaned about $wpdb->prepare HERE and added into our Free Class Booking plugin, plugin approved on wordpress.org and will live soon:

global $wpdb;
$tablename = $wpdb->prefix . "submitted_form";

$name     = "Kumkum"; //string value use: %s
$email    = "[email protected]"; //string value use: %s
$phone    = "3456734567"; //numeric value use: %d
$country  = "India"; //string value use: %s
$course   = "Database"; //string value use: %s
$message  = "hello i want to read db"; //string value use: %s
$now      = new DateTime(); //string value use: %s
$datesent = $now->format('Y-m-d H:i:s'); //string value use: %s

$sql = $wpdb->prepare("INSERT INTO `$tablename` (`name`, `email`, `phone`, `country`, `course`, `message`, `datesent`) values (%s, %s, %d, %s, %s, %s, %s)", $name, $email, $phone, $country, $course, $message, $datesent);

$wpdb->query($sql);

Note: this answer is deprecated. see other answers if you are using Django 1.7 or later.

This is how I do it.

#in models.py
from django.contrib.auth.models import User
from django.db.models.signals import post_save

class UserProfile(models.Model):  
    user = models.OneToOneField(User)  
    #other fields here

    def __str__(self):  
          return "%s's profile" % self.user  

def create_user_profile(sender, instance, created, **kwargs):  
    if created:  
       profile, created = UserProfile.objects.get_or_create(user=instance)  

post_save.connect(create_user_profile, sender=User) 

#in settings.py
AUTH_PROFILE_MODULE = 'YOURAPP.UserProfile'

This will create a userprofile each time a user is saved if it is created. You can then use

  user.get_profile().whatever

Here is some more info from the docs

http://docs.djangoproject.com/en/dev/topics/auth/#storing-additional-information-about-users

Update: Please note that AUTH_PROFILE_MODULE is deprecated since v1.5: https://docs.djangoproject.com/en/1.5/ref/settings/#auth-profile-module

“CURL ERROR 7 Failed to connect to Permission denied” error is caused, when for any reason curl request is blocked by some firewall or similar thing.

you will face this issue when ever the curl request is not with standard ports.

for example if you do curl to some URL which is on port 1234, you will face this issue where as URL with port 80 will give you results easily.

Most commonly this error has been seen on CentOS and any other OS with ‘SElinux’.

you need to either disable or change ’SElinux’ to permissive

have a look on this one

Hope this helps

With Bootstrap 4 (which is in alpha currently) you can use the .align-items-center class. So you can keep the responsive character of Bootstrap. Workes straight away fine for me. See Bootstrap 4 Documentation.

To make vim the default editor for git on ubuntu 20:04 run the following command:

git config --global core.editor vim

Instead of calling /usr/bin/gcc, use /usr/bin/c99. This is the Single-Unix-approved way of invoking a C99 compiler. On an Ubuntu system, this points to a script which invokes gcc after having added the -std=c99 flag, which is precisely what you want.

You can use str.isalpha().

For example:

s = 'a123b'

for char in s:
    print(char, char.isalpha())

Output:

a True
1 False
2 False
3 False
b True

The use of that is not really necessary if you make a workaround with the use of call() or apply():

var car = {};
car.starter = {};

car.start = function(){
    this.starter.active = false;

    var activateStarter = function(){
        // 'this' now points to our main object
        this.starter.active = true;
    };

    activateStarter.apply(this);
};

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

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

PDO Extension

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

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

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

USE[Database] SELECT TABLE_NAME,TABLE_SCHEMA,[Column_Name],[Data_type] FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA='dbo'

Another short solution:

from datetime import date

def diff_dates(date1, date2):
    return abs(date2-date1).days

def main():
    d1 = date(2013,1,1)
    d2 = date(2013,9,13)
    result1 = diff_dates(d2, d1)
    print '{} days between {} and {}'.format(result1, d1, d2)
    print ("Happy programmer's day!")

main()

It's useful if you want to separate allocation from initialization. STL uses placement new to create container elements.

clock() -> floating point number

Return the CPU time or real time since the start of the process or since the first call to clock(). This has as much precision as the system records.

time() -> floating point number

Return the current time in seconds since the Epoch. Fractions of a second may be present if the system clock provides them.

Usually time() is more precise, because operating systems do not store the process running time with the precision they store the system time (ie, actual time)

Just use String.IndexOf twice as in:

     string str = "My Test String";
     int index = str.IndexOf(' ');
     index = str.IndexOf(' ', index + 1);
     string result = str.Substring(0, index);

Since localStorage is a global object, you can add a watch in the dev tools. Just enter the dev tools, goto "watch", click on "Click to add..." and type in "localStorage".

Both if (one.length() > 0) {} and if (!"".equals(one)) {} will check against an empty foo parameter, and an empty parameter is what you'd get if the the form is submitted with no value in the foo text field.

If there's any chance you can use the Expression Language to handle the parameter, you could access it with empty param.foo in an expression.

<c:if test='${not empty param.foo}'>
    This page code gets rendered.
</c:if>

Another possibility of making.

actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#0000ff")));

I think this is better, following the good practices of passing parameters to the query:

BookingDates::whereRaw('email = ? or name like ?', [$request->email,"%{$request->name}%"])->get();

You can see it in the documentation, Laravel 5.5.

You can also use the Laravel scout and make it easier with search. Here is the documentation.

Personally, I always go for a mixture of the above answers and create a re-usable static Utility method that uses the size() > 0 suggestion:

public Class Utility {
   ...
   public static boolean isElementExist(WebDriver driver, By by) {
      return driver.findElements(by).size() > 0;
   ...
}

This is neat, re-usable, maintainable ... all that good stuff ;-)

You are getting Floating point exception because Number % i, when i is 0:

int Is_Prime( int Number ){

  int i ;

  for( i = 0 ; i < Number / 2 ; i++ ){

    if( Number % i != 0 ) return -1 ;

  }

  return Number ;

}

Just start the loop at i = 2. Since i = 1 in Number % i it always be equal to zero, since Number is a int.

an alternative would be to do something like:

SELECT
   CAST(P0.seconds as bigint) as seconds
FROM
   (
   SELECT
      seconds
   FROM
      TableName
   WHERE
      ISNUMERIC(seconds) = 1
   ) P0

Maybe you can use this properties:

ActiveCell.Interior.ColorIndex - one of 56 preset colors

and

ActiveCell.Interior.Color - RGB color, used like that:

ActiveCell.Interior.Color = RGB(255,255,255)

You actually had it correct in your third attempt.

 <select ng-model="myselect" ng-options="o as o for o in options"></select>

See a working example here: http://plnkr.co/edit/xEERH2zDQ5mPXt9qCl6k?p=preview

The trick is that AngularJS writes the keys as numbers from 0 to n anyway, and translates back when updating the model.

As a result, the HTML will look incorrect but the model will still be set properly when choosing a value. (i.e. AngularJS will translate '0' back to 'var1')

The solution by Epokk also works, however if you're loading data asynchronously you might find it doesn't always update correctly. Using ngOptions will correctly refresh when the scope changes.

I have a function next() which will maybe inspire you.

function queue(target) {
        var array = Array.prototype;

        var queueing = [];

        target.queue = queue;
        target.queued = queued;

        return target;

        function queued(action) {
            return function () {
                var self = this;
                var args = arguments;

                queue(function (next) {
                    action.apply(self, array.concat.apply(next, args));
                });
            };
        }

        function queue(action) {
            if (!action) {
                return;
            }

            queueing.push(action);

            if (queueing.length === 1) {
                next();
            }
        }

        function next() {
            queueing[0](function (err) {
                if (err) {
                    throw err;
                }

                queueing = queueing.slice(1);

                if (queueing.length) {
                    next();
                }
            });
        }
    }

While working on a .Net app build with EF code first, I got this error message when trying to apply my migration where I had a Sql("UPDATE tableName SET columnName = value"); statement.

Turns out I misspelled the columnName.

For anybody who work in VB.NET (just in case)

Dim dv As DataView = yourDatatable.DefaultView

dv.RowFilter ="query" ' ex: "parentid = 0"

Assuming a bit more memory usage is not a problem and if the first item of your tuple is hashable, you can create a dict out of your list of tuples and then looking up the value is as simple as looking up a key from the dict. Something like:

dct = dict(tuples)
val = dct.get(key) # None if item not found else the corresponding value

EDIT: To create a reverse mapping, use something like:

revDct = dict((val, key) for (key, val) in tuples)

origin/xxx branches are always pointer to a remote. You cannot check them out as they're not pointer to your local repository (you only checkout the commit. That's why you won't see the name written in the command line interface branch marker, only the commit hash).

What you need to do to update the remote is to force push your local changes to master:

git checkout master
git reset --hard e3f1e37
git push --force origin master
# Then to prove it (it won't print any diff)
git diff master..origin/master

You could use the following, which reports the timezone offset from GMT in minutes:

new Date().getTimezoneOffset();

Note : - this function return a negative number.

I prefer using the dateutil library for timezone handling and generally solid date parsing. If you were to get an ISO 8601 string like: 2010-05-08T23:41:54.000Z you'd have a fun time parsing that with strptime, especially if you didn't know up front whether or not the timezone was included. pyiso8601 has a couple of issues (check their tracker) that I ran into during my usage and it hasn't been updated in a few years. dateutil, by contrast, has been active and worked for me:

import dateutil.parser
yourdate = dateutil.parser.parse(datestring)

COPY README.md package.json gulpfile.js __BUILD_NUMBER ./

or

COPY ["__BUILD_NUMBER", "README.md", "gulpfile", "another_file", "./"]

You can also use wildcard characters in the sourcefile specification. See the docs for a little more detail.

Directories are special! If you write

COPY dir1 dir2 ./

that actually works like

COPY dir1/* dir2/* ./

If you want to copy multiple directories (not their contents) under a destination directory in a single command, you'll need to set up the build context so that your source directories are under a common parent and then COPY that parent.

An alternative is to use the Alpine Linux containers, e.g. python:2.7-alpine. They offer pip out of the box (and have a smaller footprint which leads to faster builds etc).

you don't need define positioning when you need vertical align center for inline and block elements you can take mentioned below idea:-

inline-elements :- <img style="vertical-align:middle" ...>
                   <span style="display:inline-block; vertical-align:middle"> foo<br>bar </span>  

block-elements :- <td style="vertical-align:middle"> ... </td>
                  <div style="display:table-cell; vertical-align:middle"> ... </div>

see the demo:- http://jsfiddle.net/Ewfkk/2/

A today extension would be the most fitting solution.

Also you could do something on the lock screen with local notifications queued up to fire at regular intervals showing the latest countdown value.

You need a little statistical knowledge to see this. R squared between two vectors is just the square of their correlation. So you can define you function as:

rsq <- function (x, y) cor(x, y) ^ 2

Sandipan's answer will return you exactly the same result (see the following proof), but as it stands it appears more readable (due to the evident $r.squared).

Let's do the statistics

Basically we fit a linear regression of y over x, and compute the ratio of regression sum of squares to total sum of squares.

lemma 1: a regression y ~ x is equivalent to y - mean(y) ~ x - mean(x)

lemma 2: beta = cov(x, y) / var(x)

lemma 3: R.square = cor(x, y) ^ 2

Warning

R squared between two arbitrary vectors x and y (of the same length) is just a goodness measure of their linear relationship. Think twice!! R squared between x + a and y + b are identical for any constant shift a and b. So it is a weak or even useless measure on "goodness of prediction". Use MSE or RMSE instead:

• How to obtain RMSE out of lm result?
• R - Calculate Test MSE given a trained model from a training set and a test set

I agree with 42-'s comment:

The R squared is reported by summary functions associated with regression functions. But only when such an estimate is statistically justified.

R squared can be a (but not the best) measure of "goodness of fit". But there is no justification that it can measure the goodness of out-of-sample prediction. If you split your data into training and testing parts and fit a regression model on the training one, you can get a valid R squared value on training part, but you can't legitimately compute an R squared on the test part. Some people did this, but I don't agree with it.

Here is very extreme example:

preds <- 1:4/4
actual <- 1:4

The R squared between those two vectors is 1. Yes of course, one is just a linear rescaling of the other so they have a perfect linear relationship. But, do you really think that the preds is a good prediction on actual??

In reply to wordsforthewise

Thanks for your comments 1, 2 and your answer of details.

You probably misunderstood the procedure. Given two vectors x and y, we first fit a regression line y ~ x then compute regression sum of squares and total sum of squares. It looks like you skip this regression step and go straight to the sum of square computation. That is false, since the partition of sum of squares does not hold and you can't compute R squared in a consistent way.

As you demonstrated, this is just one way for computing R squared:

preds <- c(1, 2, 3)
actual <- c(2, 2, 4)
rss <- sum((preds - actual) ^ 2)  ## residual sum of squares
tss <- sum((actual - mean(actual)) ^ 2)  ## total sum of squares
rsq <- 1 - rss/tss
#[1] 0.25

But there is another:

regss <- sum((preds - mean(preds)) ^ 2) ## regression sum of squares
regss / tss
#[1] 0.75

Also, your formula can give a negative value (the proper value should be 1 as mentioned above in the Warning section).

preds <- 1:4 / 4
actual <- 1:4
rss <- sum((preds - actual) ^ 2)  ## residual sum of squares
tss <- sum((actual - mean(actual)) ^ 2)  ## total sum of squares
rsq <- 1 - rss/tss
#[1] -2.375

Final remark

I had never expected that this answer could eventually be so long when I posted my initial answer 2 years ago. However, given the high views of this thread, I feel obliged to add more statistical details and discussions. I don't want to mislead people that just because they can compute an R squared so easily, they can use R squared everywhere.

You have to explicitly set the position of the parent container along with the position of the child container. The typical way to do that is something like this:

div.parent{
    position: relative;
    left: 0px;  /* stick it wherever it was positioned by default */
    top: 0px;
}

div.child{
    position: absolute;
    left: 10px;
    top: 10px;
}

You can use @Qualifier along with @Autowired. In fact spring will ask you explicitly select the bean if ambiguous bean type are found, in which case you should provide the qualifier

For Example in following case it is necessary provide a qualifier

@Component
@Qualifier("staff") 
public Staff implements Person {}

@Component
@Qualifier("employee") 
public Manager implements Person {}


@Component
public Payroll {

    private Person person;

    @Autowired
    public Payroll(@Qualifier("employee") Person person){
          this.person = person;
    }

}

EDIT:

In Lombok 1.18.4 it is finally possible to avoid the boilerplate on constructor injection when you have @Qualifier, so now it is possible to do the following:

@Component
@Qualifier("staff") 
public Staff implements Person {}

@Component
@Qualifier("employee") 
public Manager implements Person {}


@Component
@RequiredArgsConstructor
public Payroll {
   @Qualifier("employee") private final Person person;
}

provided you are using the new lombok.config rule copyableAnnotations (by placing the following in lombok.config in the root of your project):

# Copy the Qualifier annotation from the instance variables to the constructor
# see https://github.com/rzwitserloot/lombok/issues/745
lombok.copyableAnnotations += org.springframework.beans.factory.annotation.Qualifier

This was recently introduced in latest lombok 1.18.4.

• The blog post where the issue is discussed in detail
• The original issue on github
• And a small github project to see it in action

NOTE

If you are using field or setter injection then you have to place the @Autowired and @Qualifier on top of the field or setter function like below(any one of them will work)

public Payroll {
   @Autowired @Qualifier("employee") private final Person person;
}

or

public Payroll {
   private final Person person;
   @Autowired
   @Qualifier("employee")
   public void setPerson(Person person) {
     this.person = person;
   } 
}

If you are using constructor injection then the annotations should be placed on constructor, else the code would not work. Use it like below -

public Payroll {

    private Person person;

    @Autowired
    public Payroll(@Qualifier("employee") Person person){
          this.person = person;
    }

}

>>> s = 'sdsd'
>>> s.upper()
'SDSD'

See String Methods.

Straight answer:

String s = "Hello World!";

// String => CharSequence conversion:

CharSequence cs = s;  // String is already a CharSequence

CharSequence is an interface, and the String class implements CharSequence.

Try this

declare @v varchar(20)
set @v = 'Number'
select case when isnumeric(@v) = 1 then @v
else @v end

and

declare @v varchar(20)
set @v = '7082.7758172'
select case when isnumeric(@v) = 1 then @v
else convert(numeric(18,0),@v) end

The way I understand it is also, there should be a third term added to the mix: Task.

Async is just a qualifier you put on your method to say it's an asynchronous method.

Task is the return of the async function. It executes asynchronously.

You await a Task. When code execution reaches this line, control jumps out back to caller of your surrounding original function.

If instead, you assign the return of an async function (ie Task) to a variable, when code execution reaches this line, it just continues past that line in the surrounding function while the Task executes asynchronously.

Integer division $x divided by $y ...

$z = -1 & $x / $y

How does it work?

$x / $y

return the floating point division

&

perform a bit-wise AND

-1

stands for

&HFFFFFFFF

for the largest integer ... whence

$z = -1 & $x / $y

gives the integer division ...

C is the core language that most closely resembles and directly translates into CPU machine code. CPUs follow instructions that move, add, logically combine, compare, jump, push and pop. C does exactly this using much easier syntax. If you study the disassembly, you can learn to write C code that is just as fast and compact as assembly. It is my preferred language on 8 bit micro controllers with limited memory. If you write a large PC program in C you will get into trouble because of its limited organization. That is where object oriented programming becomes powerful. The ability of C++ and C# classes to contain data and functions together enforces organization which in turn allows more complex operability over C. C++ was essential for quick processing in the past when CPUs only had one core. I am beginning to learn C# now. Its class only structure appears to enforce a higher degree of organization than C++ which should ultimately lead to faster development and promote code sharing. C# is not interpreted like VB. It is partially compiled at development time and then further translated at run time to become more platform friendly.

I know this is an old one with an accepted answer, and that answer works great.. IF you are not styling the background and floating the final inputs left. If you are, then the form background will not include the floated input fields.

To avoid this make the divs with the smaller input fields inline-block rather than float left.

This:

<div style="display:inline-block;margin-right:20px;">
    <label for="name">Name</label>
    <input id="name" type="text" value="" name="name">
</div>

Rather than:

<div style="float:left;margin-right:20px;">
    <label for="name">Name</label>
    <input id="name" type="text" value="" name="name">
</div>

Start by adding recyclerview library.

implementation 'androidx.recyclerview:recyclerview:1.1.0'

Create model class.

     public class UserModel implements Serializable {

    private String userName;


    public UserModel(String userName) {
        this.userName = userName;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }
   }

create adapter class.

public class UsersAdapter extends RecyclerView.Adapter<UsersAdapter.UsersAdapterVh> implements Filterable {

    private List<UserModel> userModelList;
    private List<UserModel> getUserModelListFiltered;
    private Context context;
    private SelectedUser selectedUser;

    public UsersAdapter(List<UserModel> userModelList,SelectedUser selectedUser) {
        this.userModelList = userModelList;
        this.getUserModelListFiltered = userModelList;
        this.selectedUser = selectedUser;
    }

    @NonNull
    @Override
    public UsersAdapter.UsersAdapterVh onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        context = parent.getContext();

        return new UsersAdapterVh(LayoutInflater.from(context).inflate(R.layout.row_users,null));
    }

    @Override
    public void onBindViewHolder(@NonNull UsersAdapter.UsersAdapterVh holder, int position) {

        UserModel userModel = userModelList.get(position);

        String username = userModel.getUserName();
        String prefix = userModel.getUserName().substring(0,1);

        holder.tvUsername.setText(username);
        holder.tvPrefix.setText(prefix);

    }

    @Override
    public int getItemCount() {
        return userModelList.size();
    }

    @Override
    public Filter getFilter() {

        Filter filter = new Filter() {
            @Override
            protected FilterResults performFiltering(CharSequence charSequence) {
                FilterResults filterResults = new FilterResults();

                if(charSequence == null | charSequence.length() == 0){
                    filterResults.count = getUserModelListFiltered.size();
                    filterResults.values = getUserModelListFiltered;

                }else{
                    String searchChr = charSequence.toString().toLowerCase();

                    List<UserModel> resultData = new ArrayList<>();

                    for(UserModel userModel: getUserModelListFiltered){
                        if(userModel.getUserName().toLowerCase().contains(searchChr)){
                            resultData.add(userModel);
                        }
                    }
                    filterResults.count = resultData.size();
                    filterResults.values = resultData;

                }

                return filterResults;
            }

            @Override
            protected void publishResults(CharSequence charSequence, FilterResults filterResults) {

                userModelList = (List<UserModel>) filterResults.values;
                notifyDataSetChanged();

            }
        };
        return filter;
    }


    public interface SelectedUser{

        void selectedUser(UserModel userModel);

    }

    public class UsersAdapterVh extends RecyclerView.ViewHolder {

        TextView tvPrefix;
        TextView tvUsername;
        ImageView imIcon;
        public UsersAdapterVh(@NonNull View itemView) {
            super(itemView);
            tvPrefix = itemView.findViewById(R.id.prefix);
            tvUsername = itemView.findViewById(R.id.username);
            imIcon = itemView.findViewById(R.id.imageView);

            itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    selectedUser.selectedUser(userModelList.get(getAdapterPosition()));
                }
            });


        }
    }
}

create layout row_uses.xml

    <?xml version="1.0" encoding="utf-8"?>

    android:orientation="vertical" android:layout_width="match_parent"

Find recyclerview and populate data.

Toolbar toolbar;
RecyclerView recyclerView;

List<UserModel> userModelList = new ArrayList<>();

String[] names = {"Richard","Alice","Hannah","David"};

UsersAdapter usersAdapter;


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

    recyclerView = findViewById(R.id.recyclerview);
    toolbar = findViewById(R.id.toolbar);

    this.setSupportActionBar(toolbar);
    this.getSupportActionBar().setTitle("");

    recyclerView.setLayoutManager(new LinearLayoutManager(this));
    recyclerView.addItemDecoration(new DividerItemDecoration(this,DividerItemDecoration.VERTICAL));

    for(String s:names){
        UserModel userModel = new UserModel(s);

        userModelList.add(userModel);
    }

    usersAdapter = new UsersAdapter(userModelList,this);

    recyclerView.setAdapter(usersAdapter);

}

Android RecyclerView

"ClearCurrentConsoleLine", "ClearLine" and the rest of the above functions should use Console.BufferWidth instead of Console.WindowWidth (you can see why when you try to make the window smaller). The window size of the console currently depends of its buffer and cannot be wider than it. Example (thanks goes to Dan Cornilescu):

public static void ClearLastLine()
{
    Console.SetCursorPosition(0, Console.CursorTop - 1);
    Console.Write(new string(' ', Console.BufferWidth));
    Console.SetCursorPosition(0, Console.CursorTop - 1);
}

Well, you can use xpath utility. I guess perl's XML::Xpath contains it.

net user %username% >nul 2>&1 && echo admin || echo not admin

Its blank because you are writing to file. you should write to output using php://output instead and also send header information to indicate that it's csv.

Example

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');
$data = array(
        'aaa,bbb,ccc,dddd',
        '123,456,789',
        '"aaa","bbb"'
);

$fp = fopen('php://output', 'wb');
foreach ( $data as $line ) {
    $val = explode(",", $line);
    fputcsv($fp, $val);
}
fclose($fp);

If you want MySQL to automatically produce primary keys then you have to tell it when creating the table. You don't have to do this in Oracle.

On the Primary Key you have to include AUTO_INCREMENT. See the example below.

CREATE TABLE `supplier`  
(  
  `ID` int(11) NOT NULL **AUTO_INCREMENT**,  
  `FIRSTNAME` varchar(60) NOT NULL,  
  `SECONDNAME` varchar(100) NOT NULL,  
  `PROPERTYNUM` varchar(50) DEFAULT NULL,  
  `STREETNAME` varchar(50) DEFAULT NULL,  
  `CITY` varchar(50) DEFAULT NULL,  
  `COUNTY` varchar(50) DEFAULT NULL,  
  `COUNTRY` varchar(50) DEFAULT NULL,  
  `POSTCODE` varchar(50) DEFAULT NULL,  
  `HomePHONENUM` bigint(20) DEFAULT NULL,  
  `WorkPHONENUM` bigint(20) DEFAULT NULL,  
  `MobilePHONENUM` bigint(20) DEFAULT NULL,  
  `EMAIL` varchar(100) DEFAULT NULL,  
  PRIMARY KEY (`ID`)  
)

THIRD VERSION OF MY ANSWER:

Here's a multiple line example of inline Jade Javascript. I don't think you can write it without using a -. This is a flash message example that I use in a partial. Hope this helps!

-if(typeof(info) !== 'undefined')
  -if (info)
    - if(info.length){
      ul
        -info.forEach(function(info){
          li= info
      -})
  -}

Is the code you're trying to get to compile the code in your question?

If so, you don't need two things: first, you don't need to declare that it's Javascript/a script, you can just started coding after typing -; second, after you type -if you don't need to type the { or } either. That's what makes Jade pretty sweet.

--------------ORIGINAL ANSWER BELOW ---------------

Try prepending if with -:

-if(10 == 10)
  //do whatever you want here as long as it's indented two spaces from
   the `-` above

There are also tons of Jade examples at:

https://github.com/visionmedia/jade/blob/master/examples/

For my case I had to specify a tab index (-1 if only focusable via script)

<div tabindex='-1'>
<!-- ... -->
</div>
