You need to add your source files with git add or the GUI equivalent so that Git will begin tracking them.

Use git status to see what Git thinks about the files in any given directory.

I've found out a nice workaround to IP blocking when scraping sites. It lets you run a Scraper indefinitely by running it from Google App Engine and redeploying it automatically when you get a 429.

Check out this article

URL yahoo = new URL("http://www.yahoo.com/");
BufferedReader in = new BufferedReader(
            new InputStreamReader(
            yahoo.openStream()));

String inputLine;

while ((inputLine = in.readLine()) != null)
    System.out.println(inputLine);

in.close();

Try PHPMyAdmin which has some really nice visualisation and editing feature. I am pretty sure you can even export to exel from it.

If you want to accomplish the same in Gecko (NS6+, Mozilla, etc) and IE4+ simultaneously, I believe this should do the trick:V

body {
overflow: -moz-scrollbars-vertical;
overflow-x: hidden;
overflow-y: auto;
}

This will be applied to entire body tag, please update it to your relevant css and apply this properties.

string.substring(start,end)

where

start = Required. The position where to start the extraction. First character is at index 0`.

end = Optional. The position (up to, but not including) where to end the extraction. If omitted, it extracts the rest of the string.

    var string = "var1/var2/var3";

    start   = string.lastIndexOf('/');  //console.log(start); o/p:- 9
    end     = string.length;            //console.log(end);   o/p:- 14

    var string_before_last_slash = string.substring(0, start);
    console.log(string_before_last_slash);//o/p:- var1/var2

    var string_after_last_slash = string.substring(start+1, end);
    console.log(string_after_last_slash);//o/p:- var3

OR

    var string_after_last_slash = string.substring(start+1);
    console.log(string_after_last_slash);//o/p:- var3

A decimal will always have some default value. If you need to have a nullable type decimal, you can use decimal?. Then you can do myDecimal.HasValue

To add to the above answer for sql developer plugin, using the below xml will help in getting the column associated with the foreign key.

    <items>
        <item type="editor" node="TableNode" vertical="true">
        <title><![CDATA[FK References]]></title>
        <query>
            <sql>
                <![CDATA[select a.owner,
                                a.constraint_name,
                                a.table_name,
                                b.column_name,
                                a.status

I think, this could be done without IIS URL Rewrite module. <httpRedirect> supports wildcards, so you can configure it this way:

  <system.webServer>
    <httpRedirect enabled="true">
      <add wildcard="/" destination="/menu_1/MainScreen.aspx" />
    </httpRedirect>
  </system.webServer>

Note that you need to have the "HTTP Redirection" feature enabled on IIS - see HTTP Redirects

Surely this whole question should be:

"How do I obtain the horizontal and vertical PPI (Pixels Per Inch) of the monitor?"

There are 72 points in an inch (by definition, a "point" is defined as 1/72nd of an inch, likewise a "pica" is defined as 1/72nd of a foot). With these two bits of information you can convert from px to pt and back very easily.

If you're using glibc, you can set the MALLOC_CHECK_ environment variable to 2, this will cause glibc to use an error tolerant version of malloc, which will cause your program to abort at the point where the double free is done.

You can set this from gdb by using the set environment MALLOC_CHECK_ 2 command before running your program; the program should abort, with the free() call visible in the backtrace.

see the man page for malloc() for more information

These are really two questions.

The first one is answered here: Calling a Sub in VBA

To the second one, protip: there is no main subroutine in VBA. Forget procedural, general-purpose languages. VBA subs are "macros" - you can run them by hitting Alt+F8 or by adding a button to your worksheet and calling up the sub you want from the automatically generated "ButtonX_Click" sub.

Just FYI, Geocoder is asynchronous so the accepted answer while logical doesn't really work in this instance. I would prefer to have an outside object that acts as your updater.

var updater = {};

function geoCodeCity(goocoord) { 
    var geocoder = new google.maps.Geocoder();
    geocoder.geocode({
        'latLng': goocoord
    }, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            updater.currentLocation = results[1].formatted_address;
        } else {
            if (status == "ERROR") { 
                    console.log(status);
                }
        }
    });
};

Here are three solutions that I know. The second might be argued though.

// compile time recursion
template<int N> void f1()
{ 
    f1<N-1>(); 
    cout << N << '\n'; 
}

template<> void f1<1>() 
{ 
    cout << 1 << '\n'; 
}

// short circuiting (not a conditional statement)
void f2(int N)
{ 
    N && (f2(N-1), cout << N << '\n');
}

// constructors!
struct A {
    A() {
        static int N = 1;
        cout << N++ << '\n';
    }
};

int main()
{
    f1<1000>();
    f2(1000);
    delete[] new A[1000]; // (3)
    A data[1000]; // (4) added by Martin York
}

[ Edit: (1) and (4) can be used for compile time constants only, (2) and (3) can be used for runtime expressions too — end edit. ]

Jaap's answer won't work for AppCompatActivity. Instead get the height of the Status Bar and Navigation bar etc and compare to your app's window size.

Like so:

    private ViewTreeObserver.OnGlobalLayoutListener keyboardLayoutListener = new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        // navigation bar height
        int navigationBarHeight = 0;
        int resourceId = getResources().getIdentifier("navigation_bar_height", "dimen", "android");
        if (resourceId > 0) {
            navigationBarHeight = getResources().getDimensionPixelSize(resourceId);
        }

        // status bar height
        int statusBarHeight = 0;
        resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resourceId > 0) {
            statusBarHeight = getResources().getDimensionPixelSize(resourceId);
        }

        // display window size for the app layout
        Rect rect = new Rect();
        getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);

        // screen height - (user app height + status + nav) ..... if non-zero, then there is a soft keyboard
        int keyboardHeight = rootLayout.getRootView().getHeight() - (statusBarHeight + navigationBarHeight + rect.height());

        if (keyboardHeight <= 0) {
            onHideKeyboard();
        } else {
            onShowKeyboard(keyboardHeight);
        }
    }
};

The "dropzone.js" is the most common library for uploading images. If you want to have the "dropzone.js" as just part of your form, you should do the following steps:

1) for the client side:

HTML :

    <form action="/" enctype="multipart/form-data" method="POST">
        <input type="text" id ="Username" name ="Username" />
        <div class="dropzone" id="my-dropzone" name="mainFileUploader">
            <div class="fallback">
                <input name="file" type="file" multiple />
            </div>
        </div>
    </form>
    <div>
        <button type="submit" id="submit-all"> upload </button>
    </div>

JQuery:

    <script>
        Dropzone.options.myDropzone = {
            url: "/Account/Create",
            autoProcessQueue: false,
            uploadMultiple: true,
            parallelUploads: 100,
            maxFiles: 100,
            acceptedFiles: "image/*",

            init: function () {

                var submitButton = document.querySelector("#submit-all");
                var wrapperThis = this;

                submitButton.addEventListener("click", function () {
                    wrapperThis.processQueue();
                });

                this.on("addedfile", function (file) {

                    // Create the remove button
                    var removeButton = Dropzone.createElement("<button class='btn btn-lg dark'>Remove File</button>");

                    // Listen to the click event
                    removeButton.addEventListener("click", function (e) {
                        // Make sure the button click doesn't submit the form:
                        e.preventDefault();
                        e.stopPropagation();

                        // Remove the file preview.
                        wrapperThis.removeFile(file);
                        // If you want to the delete the file on the server as well,
                        // you can do the AJAX request here.
                    });

                    // Add the button to the file preview element.
                    file.previewElement.appendChild(removeButton);
                });

                this.on('sendingmultiple', function (data, xhr, formData) {
                    formData.append("Username", $("#Username").val());
                });
            }
        };
    </script>

2) for the server side:

ASP.Net MVC

    [HttpPost]
    public ActionResult Create()
    {
        var postedUsername = Request.Form["Username"].ToString();
        foreach (var imageFile in Request.Files)
        {

        }

        return Json(new { status = true, Message = "Account created." });
    }

i would assume fastest and simplest way would be have python call the system commands...

example..

import os
cmd = '<command line call>'
os.system(cmd)

Tar and gzip up the directory.... unzip and untar the directory in the desired place.

yah?

None of the above worked for me.

Here's my solution- works great:

$dropTarget.droppable({
    drop: function( event, ui ) {

    // Get mouse position relative to drop target: 
    var dropPositionX = event.pageX - $(this).offset().left;
    var dropPositionY = event.pageY - $(this).offset().top;
    // Get mouse offset relative to dragged item:
    var dragItemOffsetX = event.offsetX;
    var dragItemOffsetY = event.offsetY;
    // Get position of dragged item relative to drop target:
    var dragItemPositionX = dropPositionX-dragItemOffsetX;
    var dragItemPositionY = dropPositionY-dragItemOffsetY;

    alert('DROPPED IT AT ' + dragItemPositionX + ', ' + dragItemPositionY);

(Based partly off solution given here: https://stackoverflow.com/a/10429969/165673)

You can also do this.

//find the index of the CompanyName column
int columnIndex = thisReader.GetOrdinal("CompanyName"); 
//Get the value of the column. Will throw if the value is null.
string companyName = thisReader.GetString(columnIndex);

Here is an implementation you can use (updated to use more up to date Java conventions - for:each loop, StringBuilder instead of StringBuffer):

public static String md5(final String s) {
    final String MD5 = "MD5";
    try {
        // Create MD5 Hash
        MessageDigest digest = java.security.MessageDigest
                .getInstance(MD5);
        digest.update(s.getBytes());
        byte messageDigest[] = digest.digest();

        // Create Hex String
        StringBuilder hexString = new StringBuilder();
        for (byte aMessageDigest : messageDigest) {
            String h = Integer.toHexString(0xFF & aMessageDigest);
            while (h.length() < 2)
                h = "0" + h;
            hexString.append(h);
        }
        return hexString.toString();

    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
    return "";
}

Although it is not recommended for systems that involve even the basic level of security (MD5 is considered broken and can be easily exploited), it is sometimes enough for basic tasks.

Yes, but note: since the attribute selector (of course) targets the element's attribute, not the DOM node's value property (elem.value), it will not update while the form field is being updated.

Otherwise (with some trickery) I think it could have been used to make a CSS-only substitute for the "placeholder" attribute/functionality. Maybe that's what the OP was after? :)

The port is already being used by some other process as @Diego Pino said u can use lsof on unix to locate the process and kill the respective one, if you are on windows use netstat -ano to get all the pids of the process and the ports that everyone acquires. search for your intended port and kill.

to be very easy just restart your machine , if thats possible :)

Code Example : Reading data from DataGridView and storing it in an array

int[,] n = new int[3, 19];
for (int i = 0; i < (StartDataView.Rows.Count - 1); i++)
{
    for (int j = 0; j < StartDataView.Columns.Count; j++)
    {
        if(this.StartDataView.Rows[i].Cells[j].Value.ToString() != string.Empty)
        {
            try
            {
                n[i, j] = int.Parse(this.StartDataView.Rows[i].Cells[j].Value.ToString());
            }
            catch (Exception Ee)
            { //get exception of "null"
                MessageBox.Show(Ee.ToString());
            }
        }
    }
}

.click events only work when element gets rendered and are only attached to elements loaded when the DOM is ready.

.on events are dynamically attached to DOM elements, which is helpful when you want to attach an event to DOM elements that are rendered on ajax request or something else (after the DOM is ready).

Documentation here, and I'll use the Frankfurt region as an example.

There are 2 different URL styles:

• Virtual host style: https://BUCKET.s3.amazonaws.com/FILE
• Path style: https://s3.eu-central-1.amazonaws.com/BUCKET/FILE

But this url does not work:

• https://s3.amazonaws.com/BUCKET/FILE

The message is explicit: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.

I may be talking about another problem because I'm not getting NoSuchKey error but I suspect the error message has been made clearer over time.

Is it that success() returns earlier than complete()?

Yes; the AJAX success() method runs before the complete() method.

Below is a diagram illustrating the process flow:

It is important to note that

• The success() (Local Event) is only called if the request was successful (no errors from the server, no errors with the data).

• On the other hand, the complete() (Local Event) is called regardless of if the request was successful, or not. You will always receive a complete callback, even for synchronous requests.

... more details on AJAX Events here.

Manually resolving instances involves using the IServiceProvider interface:

Resolving Dependency in Startup.ConfigureServices

public void ConfigureServices(IServiceCollection services)
{
    services.AddTransient<IMyService, MyService>();

    var serviceProvider = services.BuildServiceProvider();
    var service = serviceProvider.GetService<IMyService>();
}

Resolving Dependencies in Startup.Configure

public void Configure(
    IApplicationBuilder application,
    IServiceProvider serviceProvider)
{
    // By type.
    var service1 = (MyService)serviceProvider.GetService(typeof(MyService));

    // Using extension method.
    var service2 = serviceProvider.GetService<MyService>();

    // ...
}

Resolving Dependencies in Startup.Configure in ASP.NET Core 3

public void Configure(
    IApplicationBuilder application,
    IWebHostEnvironment webHostEnvironment)
{
    application.ApplicationServices.GetService<MyService>();
}

Using Runtime Injected Services

Some types can be injected as method parameters:

public class Startup
{
    public Startup(
        IHostingEnvironment hostingEnvironment,
        ILoggerFactory loggerFactory)
    {
    }

    public void ConfigureServices(
        IServiceCollection services)
    {
    }

    public void Configure(
        IApplicationBuilder application,
        IHostingEnvironment hostingEnvironment,
        IServiceProvider serviceProvider,
        ILoggerFactory loggerfactory,
        IApplicationLifetime applicationLifetime)
    {
    }
}

Resolving Dependencies in Controller Actions

[HttpGet("/some-action")]
public string SomeAction([FromServices] IMyService myService) => "Hello";

Here is an alternative way to get an object's property value:

write-host $(get-something).SomeProp

First represent the epoch of the millisecond time as a date (usually 1/1/1970), then add your millisecond time divided by the number of milliseconds in a day (86400000):

=DATE(1970,1,1)+(A1/86400000)

If your cell is properly formatted, you should see a human-readable date/time.

As mentioned in duscusion: WEB-INF is not really a part of class path. If you use a common template such as maven, use src/main/resources or src/test/resources to place the app-context.xml into. Then you can use 'classpath:'.

Place your config file into src/main/resources/app-context.xml and use code

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:app-context.xml")
public class PersonControllerTest {
...
}

or you can make yout test context with different configuration of beans.

Place your config file into src/test/resources/test-app-context.xml and use code

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:test-app-context.xml")
public class PersonControllerTest {
...
}

UIColor:

extension UIColor {

    convenience init(hex: Int) {
        let components = (
            R: CGFloat((hex >> 16) & 0xff) / 255,
            G: CGFloat((hex >> 08) & 0xff) / 255,
            B: CGFloat((hex >> 00) & 0xff) / 255
        )
        self.init(red: components.R, green: components.G, blue: components.B, alpha: 1)
    }

}

CGColor:

extension CGColor {

    class func colorWithHex(hex: Int) -> CGColorRef {

        return UIColor(hex: hex).CGColor

    }

}

Usage

let purple = UIColor(hex: 0xAB47BC)

There is a pretty good example on https://developers.google.com/maps/documentation/javascript/examples/geocoding-simple

To shorten it up a little:

geocoder = new google.maps.Geocoder();

function codeAddress() {

    //In this case it gets the address from an element on the page, but obviously you  could just pass it to the method instead
    var address = document.getElementById( 'address' ).value;

    geocoder.geocode( { 'address' : address }, function( results, status ) {
        if( status == google.maps.GeocoderStatus.OK ) {

            //In this case it creates a marker, but you can get the lat and lng from the location.LatLng
            map.setCenter( results[0].geometry.location );
            var marker = new google.maps.Marker( {
                map     : map,
                position: results[0].geometry.location
            } );
        } else {
            alert( 'Geocode was not successful for the following reason: ' + status );
        }
    } );
}

dropdown or select doesn't have a placeholder because HTML doesn't support it but it's possible to create same effect so it looks the same as other inputs placeholder

    $('select').change(function() {_x000D_
     if ($(this).children('option:first-child').is(':selected')) {_x000D_
       $(this).addClass('placeholder');_x000D_
     } else {_x000D_
      $(this).removeClass('placeholder');_x000D_
     }_x000D_
    });

.placeholder{color: grey;}_x000D_
select option:first-child{color: grey; display: none;}_x000D_
select option{color: #555;} // bootstrap default color

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

The following code changes the hexadecimal string to a byte array by parsing the string byte-by-byte.

public static byte[] ConvertHexStringToByteArray(string hexString)
{
    if (hexString.Length % 2 != 0)
    {
        throw new ArgumentException(String.Format(CultureInfo.InvariantCulture, "The binary key cannot have an odd number of digits: {0}", hexString));
    }

    byte[] data = new byte[hexString.Length / 2];
    for (int index = 0; index < data.Length; index++)
    {
        string byteValue = hexString.Substring(index * 2, 2);
        data[index] = byte.Parse(byteValue, NumberStyles.HexNumber, CultureInfo.InvariantCulture);
    }

    return data; 
}

You can't declare default values for the parameters like C# (I believe) lets you, but you could simply just create an overload.

public int doSomething(int arg1, int arg2) {
    //some logic here
    return 0;
}

//overload supplies default values of 1 and 2
public int doSomething() {
    return doSomething(1, 2);
}

If you are going to do something like this please do everyone else who works with your code a favor and make sure you mention in Javadoc comments what the default values you are using are!

As of version 1.3 of pip you can now use pip list

It has some useful options including the ability to show outdated packages. Here's the documentation: https://pip.pypa.io/en/latest/reference/pip_list/

Couldn't you use the server variables to do this?

Or would this work?:

unset($_GET['page']);
$url = $_SERVER['SCRIPT_NAME'] ."?".http_build_query($_GET);

Just a thought.

This question has been answered but for future reference, I would like to mention that, in the context of this question, the where and filter methods in Dataset/Dataframe supports two syntaxes: The SQL string parameters:

df2 = df1.filter(("Status = 2 or Status = 3"))

and Col based parameters (mentioned by @David ):

df2 = df1.filter($"Status" === 2 || $"Status" === 3)

It seems the OP'd combined these two syntaxes. Personally, I prefer the first syntax because it's cleaner and more generic.

this.state.data.sort((a, b) => a.item.timeM > b.item.timeM).map(
    (item, i) => <div key={i}> {item.matchID} {item.timeM} {item.description}</div>
)

s = "I     am having  a   very  nice  23!@$      day. "
sum([i.strip(string.punctuation).isalpha() for i in s.split()])

The statement above will go through each chunk of text and remove punctuations before verifying if the chunk is really string of alphabets.

Late to the game but you can also use the janitor package. This function will remove columns which are all NA, and can be changed to remove rows that are all NA as well.

df <- janitor::remove_empty(df, which = "cols")

Try purge

sudo aptitude purge phpmyadmin

Not sure this works with plain old apt-get though

Wrap each ajax call in a named function and just add them to the success callbacks of the previous call:

function callA() {
    $.ajax({
    ...
    success: function() {
      //do stuff
      callB();
    }
    });
}

function callB() {
    $.ajax({
    ...
    success: function() {
        //do stuff
        callC();
    }
    });
}

function callC() {
    $.ajax({
    ...
    });
}


callA();

The API for Log4J2 is slightly different. Also you might be using its async appender. I created a latched appender for this:

    public static class LatchedAppender extends AbstractAppender implements AutoCloseable {

    private final List<LogEvent> messages = new ArrayList<>();
    private final CountDownLatch latch;
    private final LoggerConfig loggerConfig;

    public LatchedAppender(Class<?> classThatLogs, int expectedMessages) {
        this(classThatLogs, null, null, expectedMessages);
    }
    public LatchedAppender(Class<?> classThatLogs, Filter filter, Layout<? extends Serializable> layout, int expectedMessages) {
        super(classThatLogs.getName()+"."+"LatchedAppender", filter, layout);
        latch = new CountDownLatch(expectedMessages);
        final LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
        final Configuration config = ctx.getConfiguration();
        loggerConfig = config.getLoggerConfig(LogManager.getLogger(classThatLogs).getName());
        loggerConfig.addAppender(this, Level.ALL, ThresholdFilter.createFilter(Level.ALL, null, null));
        start();
    }

    @Override
    public void append(LogEvent event) {
        messages.add(event);
        latch.countDown();
    }

    public List<LogEvent> awaitMessages() throws InterruptedException {
        assertTrue(latch.await(10, TimeUnit.SECONDS));
        return messages;
    }

    @Override
    public void close() {
        stop();
        loggerConfig.removeAppender(this.getName());
    }
}

Use it like this:

        try (LatchedAppender appender = new LatchedAppender(ClassUnderTest.class, 1)) {

        ClassUnderTest.methodThatLogs();
        List<LogEvent> events = appender.awaitMessages();
        assertEquals(1, events.size());
        //more assertions here

    }//appender removed

Use the following for complete transparency:

#00000000

When I tried with #80000000 I got a black transparent overlay which I don't want. Try to change the first two digits; it controls the level of transparency, like

#00000000
#10000000
#20000000
#30000000

You may be using old version of Mysql but surely you can use

 DELETE FROM konta WHERE taken <> ''

But there are many other options available. You can try the following ones

DELETE * from konta WHERE strcmp(taken, '') <> 0;

DELETE * from konta where NOT (taken = '');

Arrays themselves do not have that method. A List, however, does: indexOf

I've used a trick so that the border is displayed outside the container. With this trick only a line is drawn so the background will be shown of the underlying view.

Here is combined solution for purging Core Data.

- (void)deleteAllObjectsInCoreData
{
    NSArray *allEntities = self.managedObjectModel.entities;
    for (NSEntityDescription *entityDescription in allEntities)
    {
        NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
        [fetchRequest setEntity:entityDescription];

        fetchRequest.includesPropertyValues = NO;
        fetchRequest.includesSubentities = NO;

        NSError *error;
        NSArray *items = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error];

        if (error) {
                NSLog(@"Error requesting items from Core Data: %@", [error localizedDescription]);
            }

        for (NSManagedObject *managedObject in items) {
            [self.managedObjectContext deleteObject:managedObject];
        }

        if (![self.managedObjectContext save:&error]) {
            NSLog(@"Error deleting %@ - error:%@", entityDescription, [error localizedDescription]);
        }
    }  
}

The == operator tests value equivalence. The is operator tests object identity, and Python tests whether the two are really the same object (i.e., live at the same address in memory).

>>> a = 'banana'
>>> b = 'banana'
>>> a is b
True

In this example, Python only created one string object, and both a and b refers to it. The reason is that Python internally caches and reuses some strings as an optimization. There really is just a string 'banana' in memory, shared by a and b. To trigger the normal behavior, you need to use longer strings:

>>> a = 'a longer banana'
>>> b = 'a longer banana'
>>> a == b, a is b
(True, False)

When you create two lists, you get two objects:

>>> a = [1, 2, 3]
>>> b = [1, 2, 3]
>>> a is b
False

In this case we would say that the two lists are equivalent, because they have the same elements, but not identical, because they are not the same object. If two objects are identical, they are also equivalent, but if they are equivalent, they are not necessarily identical.

If a refers to an object and you assign b = a, then both variables refer to the same object:

>>> a = [1, 2, 3]
>>> b = a
>>> b is a
True

If you try appending the number like, say listName.append(4) , this will append 4 at last. But if you are trying to take <int> and then append it as, num = 4 followed by listName.append(num), this will give you an error as 'num' is of <int> type and listName is of type <list>. So do type cast int(num) before appending it.

You are correct - Sleep() causes that thread to "sleep" and the CPU will go off and process other threads (otherwise known as context switching) wheras I believe Wait keeps the CPU processing the current thread.

We have both because although it may seem sensible to let other people use the CPU while you're not using it, actualy there is an overhead to context switching - depending on how long the sleep is for, it can be more expensive in CPU cycles to switch threads than it is to simply have your thread doing nothing for a few ms.

Also note that sleep forces a context switch.

Also - in general it's not possible to control context switching - during the Wait the OS may (and will for longer waits) choose to process other threads.

On Debian, Ubuntu or Linux Mint:

$ sudo apt-get install rubygems ruby-dev

On CentOS, Fedora or RHEL:

The quickest solution that I've found is to use the filterBy filter from angular-filter, for example:

<input type="text" placeholder="Search by name or genre" ng-model="ctrl.search"/>   
<ul>
  <li ng-repeat="movie in ctrl.movies | filterBy: ['name', 'genre']: ctrl.search">
    {{movie.name}} ({{movie.genre}}) - {{movie.rating}}
  </li>
</ul>

The upside is that angular-filter is a fairly popular library (~2.6k stars on GitHub) which is still actively developed and maintained, so it should be fine to add it to your project as a dependency.

If you're writing a bash script, call it by name:

#!/bin/bash

/bin/sh is not guaranteed to be bash. This caused a ton of broken scripts in Ubuntu some years ago (IIRC).

The source builtin works just fine in bash; but you might as well just use dot like Norman suggested.

Although this question is old, it is still asked by many who use MSYS2.

I started to use it this year to replace CygWin, and I'm getting pretty satisfied.

To install make, open the MSYS2 shell and type the following commands:

# Update the package database and core system packages
pacman -Syu
# Close shell and open again if needed

# Update again
pacman -Su

# Install make
pacman -S make

# Test it (show version)
make -v

You could use Series.reindex:

import pandas as pd

idx = pd.date_range('09-01-2013', '09-30-2013')

s = pd.Series({'09-02-2013': 2,
               '09-03-2013': 10,
               '09-06-2013': 5,
               '09-07-2013': 1})
s.index = pd.DatetimeIndex(s.index)

s = s.reindex(idx, fill_value=0)
print(s)

yields

2013-09-01     0
2013-09-02     2
2013-09-03    10
2013-09-04     0

The compiler isn't smart enough to know that at least one of your if blocks will be executed. Therefore, it doesn't see that variables like annualRate will be assigned no matter what. Here's how you can make the compiler understand:

if (creditPlan == "0")
{
    // ...
}
else if (creditPlan == "1")
{
    // ...
}
else if (creditPlan == "2")
{
    // ...
}
else
{
    // ...
}

The compiler knows that with an if/else block, one of the blocks is guaranteed to be executed, and therefore if you're assigning the variable in all of the blocks, it won't give the compiler error.

By the way, you can also use a switch statement instead of ifs to maybe make your code cleaner.

As the chosen answer is pretty old, and things changed, here is the new procedure, if you use 64 bits Notepad++. 64 bits version does not come with Plugin Manager nor NppExport. All details provided here.

CSS has different pseudo selector by which you can achieve such effect. In your case you can use

:active : if you want background color only when the button is clicked and don't want to persist.

:focus: if you want background color untill the focus is on the button.

button:active{
    background:olive;
}

and

button:focus{
    background:olive;
}

UPDATE: You can do this now automatically with Excel 2013. I've created this as a new answer because my previous answer actually solves a slightly different problem.

If you have that version, then select your data to create a pivot table, and when you create your table, make sure the option 'Add this data to the Data Model' tickbox is check (see below).

Then, when your pivot table opens, create your rows, columns and values normally. Then click the field you want to calculate the distinct count of and edit the Field Value Settings:

Finally, scroll down to the very last option and choose 'Distinct Count.'

This should update your pivot table values to show the data you're looking for.

Your syntax is incorrect. To make a literal map (as a pseudo-constant), you can do:

var romanNumeralDict = map[int]string{
  1000: "M",
  900 : "CM",
  500 : "D",
  400 : "CD",
  100 : "C",
  90  : "XC",
  50  : "L",
  40  : "XL",
  10  : "X",
  9   : "IX",
  5   : "V",
  4   : "IV",
  1   : "I",
}

Inside a func you can declare it like:

romanNumeralDict := map[int]string{
...

And in Go there is no such thing as a constant map. More information can be found here.

Try it out on the Go playground.

What do you want to do with the attribute? Is it an html attribute or something of your own?

Most of the time you can simply address it as a property: want to set a title on an element? element.title = "foo" will do it.

For your own custom JS attributes the DOM is naturally extensible (aka expando=true), the simple upshot of which is that you can do element.myCustomFlag = foo and subsequently read it without issue.

This does not answer the question directly. But someone may end up here because they want to run a oneliner of R from the terminal. For example, if you just want to install some missing packages and quit, this oneliner can be very convenient. I use it a lot when I suddenly find out that I miss some packages, and I want to install them to where I want.

• To install to the default location:

  R -e 'install.packages(c("package1", "package2"))'
  

• To install to a location that requires root privileges:

  R -e 'install.packages(c("package1", "package2"), lib="/usr/local/lib/R/site-library")'

I don't agree with the statement about [...] HTTP referrer leakage (an external image in the target page might leak the password) in Slough's response.

The HTTP 1.1 RFC explicitly states:

Clients SHOULD NOT include a Referer header field in a (non-secure) HTTP request if the referring page was transferred with a secure protocol.

Anyway, server logs and browser history are more than sufficient reasons not to put sensitive data in the query string.

I have published a WPF Auto Complete Text Box in WPF at CodePlex.com. You can download and try it from https://wpfautocomplete.codeplex.com/.

<%
String session_val = (String)session.getAttribute("sessionval"); 
System.out.println("session_val"+session_val);
%>

<script type="text/javascript">
var session_obj= '<%=session_val%>';
alert("session_obj"+session_obj);

Attach an event handler to the submit event of the form. Make sure it cancels the default action.

Quirks Mode has a guide to event handlers, but you would probably be better off using a library to simplify the code and iron out the differences between browsers. All the major ones (such as YUI and jQuery) include event handling features, and there is a large collection of tiny event libraries.

Here is how you would do it in YUI 3:

<script src="http://yui.yahooapis.com/3.4.1/build/yui/yui-min.js"></script>
<script>
    YUI().use('event', function (Y) {
        Y.one('form').on('submit', function (e) {
            // Whatever else you want to do goes here
            e.preventDefault();
        });
    });
</script>

Make sure that the server will pick up the slack if the JavaScript fails for any reason.

Please find in the below code which enables to perform the date validation for any of the supplied format or based on user locale to validate start/from and end/to dates. There could be some better approaches but have come up with this. Have tested it for the formats like: MM/dd/yyyy, dd/MM/yyyy, yyyy-MM-dd, yyyy.MM.dd, yyyy/MM/dd and dd-MM-yyyy.

Note supplied date format and date string go hand in hand.

    <script type="text/javascript">
function validate(format) {

    if(isAfterCurrentDate(document.getElementById('start').value, format)) {
        alert('Date is after the current date.');
    } else {
        alert('Date is not after the current date.');
    }
    if(isBeforeCurrentDate(document.getElementById('start').value, format)) {
        alert('Date is before current date.');
    } else {
        alert('Date is not before current date.');
    }
    if(isCurrentDate(document.getElementById('start').value, format)) {
        alert('Date is current date.');
    } else {
        alert('Date is not a current date.');
    }
    if (isBefore(document.getElementById('start').value, document.getElementById('end').value, format)) {
        alert('Start/Effective Date cannot be greater than End/Expiration Date');
    } else {

    }

    <br/>
    <input type="button" value="Submit" onclick="javascript:validate('MM/dd/yyyy');" />

I like to use brackets to get value from input, its way more clear than using dots.

document.forms['form_name']['input_name'].value;

I didn't understand your question ... what do you mean by "when i set every one of my colour"? try this (edit: "#fffff" in original answer changed to "#ffffff"

  yourView.setBackgroundColor(Color.parseColor("#ffffff"));

Not sure what you are asking, but... Class.forname, maybe?

Use Controls object

For i = 1 To X
    Controls("Label" & i).Caption =  MySheet.Cells(i + 1, i).Value
Next

Use File.ReadAllText(path_to_file) to read

Although the answers above seems correct, just a simple explanation to give you an idea of how it works.

Suppose that your column is set to be DECIMAL(13,4). This means that the column will have a total size of 13 digits where 4 of these will be used for precision representation.

So, in summary, for that column you would have a max value of: 999999999.9999

If you are using bootstrap.js then the below code might be useful. This is very simple. Dont have to write anything in js to invoke the pop-up.

You have to enable Soft Wraps. Find that option through this path.

View > Active Editor > Use Soft Wraps

Let's say you want to put the image (40px X 40px) on the center (horizontal and vertical) of the div class="box". So you have the following html:

<div class="box"><img /></div>

What you have to do is apply the CSS:

.box img {
    position: absolute;
    top: 50%;
    margin-top: -20px;
    left: 50%;
    margin-left: -20px;
}

Your div can even change it's size, the image will always be on the center of it.

I have tried with it on Swift 4.2, hopefully it work for you!

@IBDesignable class PaddingLabel: UILabel {

    @IBInspectable var topInset: CGFloat = 5.0
    @IBInspectable var bottomInset: CGFloat = 5.0
    @IBInspectable var leftInset: CGFloat = 7.0
    @IBInspectable var rightInset: CGFloat = 7.0

    override func drawText(in rect: CGRect) {
        let insets = UIEdgeInsets(top: topInset, left: leftInset, bottom: bottomInset, right: rightInset)
        super.drawText(in: rect.inset(by: insets))
    }

    override var intrinsicContentSize: CGSize {
        let size = super.intrinsicContentSize
        return CGSize(width: size.width + leftInset + rightInset,
                      height: size.height + topInset + bottomInset)
    }   

    override var bounds: CGRect {
        didSet {
            // ensures this works within stack views if multi-line
            preferredMaxLayoutWidth = bounds.width - (leftInset + rightInset)
        }
    } 
}

Or you can use CocoaPods here https://github.com/levantAJ/PaddingLabel

pod 'PaddingLabel', '1.2'

Disadvantages: Technically, design and initial development of SPA is complex and can be avoided. Other reasons for not using this SPA can be:

• a) Security: Single Page Application is less secure as compared to traditional pages due to cross site scripting(XSS).
• b) Memory Leak: Memory leak in JavaScript can even cause powerful Computer to slow down. As traditional websites encourage to navigate among pages, thus any memory leak caused by previous page is almost cleansed leaving less residue behind.
• c) Client must enable JavaScript to run SPA, but in multi-page application JavaScript can be completely avoided.
• d) SPA grows to optimal size, cause long waiting time. Eg: Working on Gmail with slower connection.

Apart from above, other architectural limitations are Navigational Data loss, No log of Navigational History in browser and difficulty in Automated Functional Testing with selenium.

This link explain Single Page Application's Advantages and Disadvantages.

You can also try this:

import * as drawGauge from '../../../../js/d3gauge.js';

and just new drawGauge(this.opt); in your ts-code. This solution works in project with angular-cli embedded into laravel on which I currently working on. In my case I try to import poliglot library (btw: very good for translations) from node_modules:

import * as Polyglot from '../../../node_modules/node-polyglot/build/polyglot.min.js';
...
export class Lang 
{
    constructor() {

        this.polyglot = new Polyglot({ locale: 'en' });
        ...
    }
    ...
}

This solution is good because i don't need to COPY any files from node_modules :) .

UPDATE

You can also look on this LIST of ways how to include libs in angular.

When should I use an interface and when should I use a base class?

You should use interface if

1. You have pure abstract methods and don't have non-abstract methods
2. You don't have default implementation of non abstract methods (except for Java 8 language, where interface methods provides default implementation)
3. If you are using Java 8, now interface will provide default implementation for some non-abstract methods. This will make interface more usable compared to abstract classes.

Have a look at this SE question for more details.

Should it always be an interface if I don't want to actually define a base implementation of the methods?

Yes. It's better and cleaner. Even if you have a base class with some abstract methods, let's base class extends abstract methods through interface. You can change interface in future without changing the base class.

Example in java:

abstract class PetBase implements IPet {
// Add all abstract methods in IPet interface and keep base class clean. 
   Base class will contain only non abstract methods and static methods.
}

If I have a Dog and Cat class. Why would I want to implement IPet instead of PetBase? I can understand having interfaces for ISheds or IBarks (IMakesNoise?), because those can be placed on a pet by pet basis, but I don't understand which to use for a generic Pet.

I prefer to have base class implement the interface.

 abstract class PetBase implements IPet {
 // Add all abstract methods in IPet
 }

 /*If ISheds,IBarks is common for Pets, your PetBase can implement ISheds,IBarks. 
  Respective implementations of PetBase can change the behaviour in their concrete classes*/

 abstract class PetBase implements IPet,ISheds,IBarks {
 // Add all abstract methods in respective interfaces
 }

Advantages:

1. If I want to add one more abstract method in existing interfaces, I simple change interface without touching the abstract base class. If I want to change the contract, I will change interface & implementation classes without touching base class.

2. You can provide immutability to base class through interface. Have a look at this article

Refer to this related SE question for more details:

How should I have explained the difference between an Interface and an Abstract class?

Here is what i have done to find the version: just write SELECT @@version and it will give you the version.

if result is None:
    print "error parsing stream"
elif result:
    print "result pass"
else:
    print "result fail"

keep it simple and explicit. You can of course pre-define a dictionary.

messages = {None: 'error', True: 'pass', False: 'fail'}
print messages[result]

If you plan on modifying your simulate function to include more return codes, maintaining this code might become a bit of an issue.

The simulate might also raise an exception on the parsing error, in which case you'd either would catch it here or let it propagate a level up and the printing bit would be reduced to a one-line if-else statement.

If you’re asking what I think you’re asking, you can open it by executing this:

explorer.exe "C:\WINDOWS\Tasks\"

remove leading and trailing white space in 2nd column

awk 'BEGIN{FS=OFS=","}{gsub(/^[ \t]+/,"",$2);gsub(/[ \t]+$/,"",$2)}1' input.txt

another way by one gsub:

awk 'BEGIN{FS=OFS=","} {gsub(/^[ \t]+|[ \t]+$/, "", $2)}1' infile

You could also use a CSS "calc" to get the same effect instead of using the negative margin or transform properties (in case you want to use those properties for anything else).

.hero:after,
.hero:after {
    z-index: -1;
    position: absolute;
    top: 98.1%;
    left: calc(50% - 25px);
    content: '';
    width: 0;
    height: 0;
    border-top: solid 50px #e15915;
    border-left: solid 50px transparent;
    border-right: solid 50px transparent;
}

the correct procedure to resolve this warning, as other people write, is to go inside your project Properties and click on Java Build Path located on the left. Now you will find inside the Libraries Window the J2SE 1.5, double click on this one and a new window will give you the possibility to choose the correct Excecution Environment. Now select your version and the warning will disappear.

I have been there, like so many of us. There are so many confusing words like Web API, REST, RESTful, HTTP, SOAP, WCF, Web Services... and many more around this topic. But I am going to give brief explanation of only those which you have asked.

REST

It is neither an API nor a framework. It is just an architectural concept. You can find more details here.

RESTful

I have not come across any formal definition of RESTful anywhere. I believe it is just another buzzword for APIs to say if they comply with REST specifications.

EDIT: There is another trending open source initiative OpenAPI Specification (OAS) (formerly known as Swagger) to standardise REST APIs.

Web API

It in an open source framework for writing HTTP APIs. These APIs can be RESTful or not. Most HTTP APIs we write are not RESTful. This framework implements HTTP protocol specification and hence you hear terms like URIs, request/response headers, caching, versioning, various content types(formats).

Note: I have not used the term Web Services deliberately because it is a confusing term to use. Some people use this as a generic concept, I preferred to call them HTTP APIs. There is an actual framework named 'Web Services' by Microsoft like Web API. However it implements another protocol called SOAP.

I will use CXF also you can think of AXIS 2 .

The best way to do it may be using JAX RS Refer this example

Example:

wsimport -p stockquote http://stockquote.xyz/quote?wsdl

This will generate the Java artifacts and compile them by importing the http://stockquote.xyz/quote?wsdl.

I

By the rational of making everything multiplication I add the entry at the end of the list

    clc; clear all;
    V = rand(1024*1024*32,1);
    N = 10;
    tic; for i=1:N, V1 = V/norm(V);         end; toc % 4.5 s
    tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 7.5 s
    tic; for i=1:N, V3 = V/sqrt(V'*V);      end; toc % 4.9 s
    tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 6.8 s
    tic; for i=1:N, V1 = V/norm(V);         end; toc % 4.7 s
    tic; for i=1:N, d = 1/norm(V); V1 = V*d;end; toc % 4.9 s
    tic; for i=1:N, d = norm(V)^-1; V1 = V*d;end;toc % 4.4 s

Parameters take input before arguments. What you should do instead is add a parameter that accepts an array, and make it the first position parameter. ex:

param(
    [Parameter(Position = 0)]
    [string[]]$Hosts,
    [string]$VLAN
    )

foreach ($i in $Hosts)  
{ 
    Do-Stuff $i
}

Then call it like:

.\script.ps1 host1, host2, host3 -VLAN 2

Notice the comma between the values. This collects them in an array

If you want to use a plain javascript API, there is a good example at https://github.com/hongkiat/js-rss-reader/

The complete description at https://www.hongkiat.com/blog/rss-reader-in-javascript/

It uses fetch method as a global method that asynchronously fetches a resource. Below is a snap of code:

fetch(websiteUrl).then((res) => {
  res.text().then((htmlTxt) => {
    var domParser = new DOMParser()
    let doc = domParser.parseFromString(htmlTxt, 'text/html')
    var feedUrl = doc.querySelector('link[type="application/rss+xml"]').href
  })
}).catch(() => console.error('Error in fetching the website'))

You want:

git rm --cached [file]

If you omit the --cached option, it will also delete it from the working tree. git rm is slightly safer than git reset, because you'll be warned if the staged content doesn't match either the tip of the branch or the file on disk. (If it doesn't, you have to add --force.)

If you have a plugin within the browser which knows how to open a PDF file it will open directly. Like in case of images and HTML content.

So the alternative approach is not to send your MIME type in the response. In this way the browser will never know which plugin should open it. Hence it will give you a Save/Open dialog box.

Stab in the dark, but I was having the same exact issue. I solved it by deleting the project from my workspace (be careful not to delete from disk), and then re-imported the project and it worked fine. I think mine was caused by a bad windows shutdown (restarting windows correctly did not correct the issue). HTH.

did you try this ?

$("#yourdiv").load(url, function(){ 

         your functions goes here !!!

}); 

UPDATE tobeupdated
INNER JOIN original ON (tobeupdated.value = original.value)
SET tobeupdated.id = original.id

That should do it, and really its doing exactly what yours is. However, I prefer 'JOIN' syntax for joins rather than multiple 'WHERE' conditions, I think its easier to read

As for running slow, how large are the tables? You should have indexes on tobeupdated.value and original.value

EDIT: we can also simplify the query

UPDATE tobeupdated
INNER JOIN original USING (value)
SET tobeupdated.id = original.id

USING is shorthand when both tables of a join have an identical named key such as id. ie an equi-join - http://en.wikipedia.org/wiki/Join_(SQL)#Equi-join

Here's my hacky workaround - generate a console application (.NET Framework) that reads its own name and arguments, and then calls dotnet [nameOfExe].dll [args].

Of course this assumes that .NET is installed on the target machine.

Here's the code. Feel free to copy!

using System;
using System.Diagnostics;
using System.Text;

namespace dotNetLauncher
{
    class Program
    {
        /*
            If you make .NET Core applications, they have to be launched like .NET blah.dll args here
            This is a convenience EXE file that launches .NET Core applications via name.exe
            Just rename the output exe to the name of the .NET Core DLL file you wish to launch
        */
        static void Main(string[] args)
        {
            var exePath = AppDomain.CurrentDomain.BaseDirectory;
            var exeName = AppDomain.CurrentDomain.FriendlyName;
            var assemblyName = exeName.Substring(0, exeName.Length - 4);
            StringBuilder passInArgs = new StringBuilder();
            foreach(var arg in args)
            {
                bool needsSurroundingQuotes = false;
                if (arg.Contains(" ") || arg.Contains("\""))
                {
                    passInArgs.Append("\"");
                    needsSurroundingQuotes = true;
                }
                passInArgs.Append(arg.Replace("\"","\"\""));
                if (needsSurroundingQuotes)
                {
                    passInArgs.Append("\"");
                }

                passInArgs.Append(" ");
            }
            string callingArgs = $"\"{exePath}{assemblyName}.dll\" {passInArgs.ToString().Trim()}";

            var p = new Process
            {
                StartInfo = new ProcessStartInfo("dotnet", callingArgs)
                {
                    UseShellExecute = false
                }
            };

            p.Start();
            p.WaitForExit();
        }
    }
}

I've found this easy solution

To convert from bitmap to Base64 use this method.

private String convertBitmapToBase64(Bitmap bitmap) {
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
    byte[] byteArray = byteArrayOutputStream .toByteArray();
    return Base64.encodeToString(byteArray, Base64.DEFAULT);
}

To convert from Base64 to bitmap OR revert.

private Bitmap convertBase64ToBitmap(String b64) {
    byte[] imageAsBytes = Base64.decode(b64.getBytes(), Base64.DEFAULT);
    return BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length);
}

This will get you 90% of the way there ; )

window.$ = document.querySelectorAll.bind(document)

For Ajax, the Fetch API is now supported on the current version of every major browser. For $.ready(), DOMContentLoaded has near universal support. You Might Not Need jQuery gives equivalent native methods for other common jQuery functions.

Zepto offers similar functionality but weighs in at 10K zipped. There are custom Ajax builds for jQuery and Zepto as well as some micro frameworks, but jQuery/Zepto have solid support and 10KB is only ~1 second on a 56K modem.

Other way to do it using jQuery CSS method:

$("#id").css({display: "none"});
$("#id").css({display: "block"});

If anyone finds that any of the suggested:

python manage.py makemigrations

python manage.py migrate

python manage.py migrate --run-syncdb

fail, you may need to add a folder named "migrations" inside the app directory, and create an empty __init__.py file.

While the official docs are happy not to provide switch, I have seen a solution using dictionaries.

For example:

# define the function blocks
def zero():
    print "You typed zero.\n"

def sqr():
    print "n is a perfect square\n"

def even():
    print "n is an even number\n"

def prime():
    print "n is a prime number\n"

# map the inputs to the function blocks
options = {0 : zero,
           1 : sqr,
           4 : sqr,
           9 : sqr,
           2 : even,
           3 : prime,
           5 : prime,
           7 : prime,
}

Then the equivalent switch block is invoked:

options[num]()

This begins to fall apart if you heavily depend on fall through.

SELECT * FROM `orders` WHERE `order_date_time`  BETWEEN 1534809600 AND 1536718364

It is easy to change the implementation to List to Set:

Collection<String> stringList = new ArrayList<String>();
//Client side
stringList = new LinkedList<String>();

stringList = new HashSet<String>();
//stringList = new HashSet<>(); java 1.7 and 1.8

The simplest way in laravel 5 is:

$listings=Listing::take(10)->get();

return view('view.name',compact('listings'));

I think this should be enough.

$ echo "3/2" | bc 

Given

l1 = [a,b]
l2 = [b,a]

In Python >= 3.0

assertCountEqual(l1, l2) # True

In Python >= 2.7, the above function was named:

assertItemsEqual(l1, l2) # True

In Python < 2.7

import unittest2
assertItemsEqual(l1, l2) # True

Via six module (Any Python version)

import unittest
import six
class MyTest(unittest.TestCase):
    def test(self):
        six.assertCountEqual(self, self.l1, self.l2) # True

If you provide string values to your enum, a straight cast works just fine.

enum Color {
  Green = "Green",
  Red = "Red"
}

const color = "Green";
const colorEnum = color as Color;

Arrays in JavaScript don't use strings as keys. You will probably find that the value is there, but the key is an integer.

If you make Dict into an object, this will work:

var dict = {};
var addPair = function (myKey, myValue) {
    dict[myKey] = myValue;
};
var giveValue = function (myKey) {
    return dict[myKey];
};

The myKey variable is already a string, so you don't need more quotes.

The route:

$routeProvider.when('/Account/', { templateUrl: '/Home/Account', controller: 'HomeController' });

The menu html:

<li id="liInicio" ng-class="{'active':url=='account'}">

The controller:

angular.module('Home').controller('HomeController', function ($scope, $http, $location) {
    $scope.url = $location.url().replace(/\//g, "").toLowerCase();
...

The problem I found here is that the menu item is active only when the full page is loaded. When the partial view is loaded the menu doesn't change. Somebody knows why it happens?

You can echo a string, but catch it by piping (|) the function to something else.

You can do it with expr, though ShellCheck reports this usage as deprecated.

In my opinion, it is a good practice to run Jupyter in a dedicated workbook folder.

$ mkdir jupyter_folder
$ jupyter-notebook --notebook-dir jupyter_folder

where 'jupyter_folder' is a folder in my home.

Your data is not valid JSON format. You have [] when you should have {}:

• [] are for JSON arrays, which are called list in Python
• {} are for JSON objects, which are called dict in Python

Here's how your JSON file should look:

{
    "maps": [
        {
            "id": "blabla",
            "iscategorical": "0"
        },
        {
            "id": "blabla",
            "iscategorical": "0"
        }
    ],
    "masks": {
        "id": "valore"
    },
    "om_points": "value",
    "parameters": {
        "id": "valore"
    }
}

Then you can use your code:

import json
from pprint import pprint

with open('data.json') as f:
    data = json.load(f)

pprint(data)

With data, you can now also find values like so:

data["maps"][0]["id"]
data["masks"]["id"]
data["om_points"]

Try those out and see if it starts to make sense.

According to Angular 1 documentation of ngShow and ngHide, both of these directive adds the css style display: none !important;, to the element according to the condition of that directive (for ngShow adds the css on false value, and for ngHide adds the css for true value).

We can achieve this behavior using Angular 2 directive ngClass:

/* style.css */
.hide 
{
    display: none !important;
}

<!-- old angular1 ngShow -->
<div ng-show="ngShowVal"> I'm Angular1 ngShow... </div>

<!-- become new angular2 ngClass -->
<div [ngClass]="{ 'hide': !ngShowVal }"> I'm Angular2 ngShow... </div>

<!-- old angular2 ngHide -->
<div ng-hide="ngHideVal"> I'm Angular1 ngHide... </div>

<!-- become new angular2 ngClass -->
<div [ngClass]="{ 'hide': ngHideVal }"> I'm Angular2 ngHide... </div>

Notice that for show behavior in Angular2 we need to add ! (not) before the ngShowVal, and for hide behavior in Angular2 we don't need to add ! (not) before the ngHideVal.

The aforementioned killall -9 node, suggested by Patrick works as expected and solves the problem but you may want to read the edit part of this very answer about why kill -9 may not be the best way to do it.

On top of that you might want to target a single process rather than blindly killing all active processes.

In that case, first get the process ID (PID) of the process running on that port (say 8888):

lsof -i tcp:8888

This will return something like:

COMMAND   PID    USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
node     57385   You   11u  IPv6 0xac745b2749fd2be3      0t0  TCP *:ddi-tcp-1

(LISTEN) Then just do (ps - actually do not. Please keep reading below):

kill -9 57385

Have a look at using FileInfo.Name Property

something like

string[] files = Directory.GetFiles(dir); 

for (int iFile = 0; iFile < files.Length; iFile++)
    string fn = new FileInfo(files[iFile]).Name;

Also have a look at using DirectoryInfo Class and FileInfo Class

I was facing same error. I have configured slf4j-api, slf4j-log4j12 and log4j, in my local development. All configuration was fine, but slf4j-log4j12 dependency which I copied from mvnrepository had test scope <scope>test</scope>. When I removed this every thing is fine.

Some times silly mistakes breaks our head ;)

TMTOWTDI, chose the method that best fits how you work. I use the environment method so I don't have to think about it.

In the environment:

export PERL_UNICODE=SDL

on the command line:

perl -CSDL -le 'print "\x{1815}"';

or with binmode:

binmode(STDOUT, ":utf8");          #treat as if it is UTF-8
binmode(STDIN, ":encoding(utf8)"); #actually check if it is UTF-8

or with PerlIO:

open my $fh, ">:utf8", $filename
    or die "could not open $filename: $!\n";

open my $fh, "<:encoding(utf-8)", $filename
    or die "could not open $filename: $!\n";

or with the open pragma:

use open ":encoding(utf8)";
use open IN => ":encoding(utf8)", OUT => ":utf8";

This can be done fairly easily using a Lombok generated equals and a static EMPTY object:

import lombok.Data;

public class EmptyCheck {
    public static void main(String[] args) {
        User user1 = new User();

        User user2 = new User();
        user2.setName("name");

        System.out.println(user1.isEmpty()); // prints true
        System.out.println(user2.isEmpty()); // prints false
    }

    @Data
    public static class User {
        private static final User EMPTY = new User();

        private String id;
        private String name;
        private int age;

        public boolean isEmpty() {
            return this.equals(EMPTY);
        }
    }
}

Prerequisites:

• Default constructor should not be implemented with custom behavior as that is used to create the EMPTY object
• All fields of the class should have an implemented equals (built-in Java types are usually not a problem, in case of custom types you can use Lombok)

Advantages:

• No reflection involved
• As new fields added to the class, this does not require any maintenance as due to Lombok they will be automatically checked in the equals implementation
• Unlike some other answers this works not just for null checks but also for primitive types which have a non-null default value (e.g. if field is int it checks for 0, in case of boolean for false, etc.)

You're mixing notations. It should be:

<img src="folder/file.jpg" width="200" height="200">

(note, no px). Or:

<img src="folder/file.jpg" style="width: 200px; height: 200px;">

(using the style attribute) The style attribute could be replaced with the following CSS:

#mydiv img {
    width: 200px;
    height: 200px;
}

or

#mydiv img {
    width: 100%;
    height: 100%;
}

You have to write your own compareTo() method that has the Java code needed to perform the comparison.

If we wanted for example to compare two public fields, campus, then faculty, we might do something like:

int compareTo(GraduationCeremony gc)
{
    int c = this.campus.compareTo(gc.campus);

    if( c != 0 )
    {
        //sort by campus if we can
        return c;
    }
    else
    {
        //campus equal, so sort by faculty
        return this.faculty.compareTo(gc.faculty);
    }
}

This is simplified but hopefully gives you an idea. Consult the Comparable and Comparator docs for more info.

tl;dr: git diff <local branch> <remote branch>

When using git on the shell, I like to first orient myself by looking around. Here's a command to show all branches

$ git branch -a  # (or git branch --all) 
* my-branch
  master
  remotes/origin/some-branch
  remotes/origin/HEAD -> origin/master
  remotes/origin/my-branch
  remotes/origin/some-other-branch
  remotes/origin/master

Here I have two local branches (my-branch and master) and 4 remote (some-branch, some-other-branch, master, and my-branch).

Also, the asterisk next to my-branch signals the fact that I'm currently in that branch (you would also know that by using the command git status that would output: On branch my-branch.).

Note: the remote branches in the git bash shell are shown in red while the local ones are shown in green.

If you just want to show remote branches:

$ git branch -r # (or git branch --remotes)
  origin/some-branch
  origin/HEAD -> origin/master
  origin/my-branch
  origin/some-other-branch
  origin/master

To show just local branches you might be tempted to use git branch -l but that's a completely different command. To show local branches use git branch with no options

$ git branch
* my-branch 
  master

To complete a review of the basic branch options there's the --list that contrary to what you might expect is there to allow filtering. Use it with a pattern like this:

$ git branch --list 'my*'
* my-branch

You can also combine --list with the options -a and -r but make sure to adapt your pattern accordingly (remember: remote branches start with "remotes"). Example:

# this will show all branches (local & remote) that start with my
$ git branch --list 'my*' -a
* my-branch

# better: the pattern includes the remote
$ git branch --list '*my*' -a
* my-branch
  remotes/origin/my-branch

Docs: https://git-scm.com/docs/git-branch

Now you can compare any two branches from all the available ones (you can also compare two locals or two remotes).

Here I'm comparing the local with the remote my-branch, they're synchronized so I don't get any output:

$ git diff my-branch remotes/origin/my-branch

Note: you have to give the full names of the branches with no quotation marks.

I can also compare the local my-branch to the remote master. Here I get some output because the remote my-branch hasn't been merged into the master branch.

$ git diff my-branch remotes/origin/master
diff --git a/src/controllers/call.controller.js b/src/controllers/call.controller.js

X-code is primarily made for OS-X or iPhone development on Mac systems. Versions for Windows are not available. However this might help!

There is no way to get Xcode on Windows; however you can use a different SDK like Corona instead although it will not use Objective-C (I believe it uses Lua). I have however heard that it is horrible to use.

The text from the Tortoise reference:

Update item to revision Update your working copy to the selected revision. Useful if you want to have your working copy reflect a time in the past, or if there have been further commits to the repository and you want to update your working copy one step at a time. It is best to update a whole directory in your working copy, not just one file, otherwise your working copy could be inconsistent.

If you want to undo an earlier change permanently, use Revert to this revision instead.

Revert to this revision Revert to an earlier revision. If you have made several changes, and then decide that you really want to go back to how things were in revision N, this is the command you need. The changes are undone in your working copy so this operation does not affect the repository until you commit the changes. Note that this will undo all changes made after the selected revision, replacing the file/folder with the earlier version.

If your working copy is in an unmodified state, after you perform this action your working copy will show as modified. If you already have local changes, this command will merge the undo changes into your working copy.

What is happening internally is that Subversion performs a reverse merge of all the changes made after the selected revision, undoing the effect of those previous commits.

If after performing this action you decide that you want to undo the undo and get your working copy back to its previous unmodified state, you should use TortoiseSVN ? Revert from within Windows Explorer, which will discard the local modifications made by this reverse merge action.

If you simply want to see what a file or folder looked like at an earlier revision, use Update to revision or Save revision as... instead.

There are a lot of tricks to deal with History and window.location.hash in IE browsers:

• As original question said, if you go from page a.html#b to a.html#c, and then hit the back button, the browser doesn't know that page has changed. Let me say it with an example: window.location.href will be 'a.html#c', no matter if you are in a.html#b or a.html#c.

• Actually, a.html#b and a.html#c are stored in history only if elements '<a name="#b">' and '<a name="#c">' exists previously in the page.

• However, if you put an iframe inside a page, navigate from a.html#b to a.html#c in that iframe and then hit the back button, iframe.contentWindow.document.location.href changes as expected.

• If you use 'document.domain=something' in your code, then you can't access to iframe.contentWindow.document.open()' (and many History Managers does that)

I know this isn't a real response, but maybe IE-History notes are useful to somebody.

If you want to edit that file (or any file in generally), you can't edit it simply writing its name in terminal. You must to use a command to a text editor to do this. For example:

nano ~/.bashrc

or

gedit ~/.bashrc

And in general, for any type of file:

xdg-open ~/.bashrc

Writing only ~/.bashrc in terminal, this will try to execute that file, but .bashrc file is not meant to be an executable file. If you want to execute the code inside of it, you can source it like follow:

source ~/.bashrc

or simple:

. ~/.bashrc 

You can also face problems if a subdirectory itself is a git repository - ie .has a .git directory - check with ls -a.

To remove go to the subdirectory and rm .git -rf.

On my machine (Win10), the uninstaller was located at C:\ProgramData\Anaconda3\Uninstall-Anaconda3.exe.

I considered giving a comment under the answer by taggon to this very question, but well, i felt it owed more explanation for those interested in details.

Uncaught TypeError: Cannot read property 'value' of undefined is strictly a JavaScript error.
(Note that value can be anything, but for this question value is 'map')

It's critical to understand that point, just so you avoid endless debugging cycles.
This error is common especially if just starting out in JavaScript (and it's libraries/frameworks).
For React, this has a lot to do with understanding the component lifecycle methods.

// Follow this example to get the context
// Ignore any complexity, focus on how 'props' are passed down to children

import React, { useEffect } from 'react'

// Main component
const ShowList = () => {
  // Similar to componentDidMount and componentDidUpdate
  useEffect(() => {// dispatch call to fetch items, populate the redux-store})

  return <div><MyItems items={movies} /></div>
}

// other component
const MyItems = props =>
  <ul>
    {props.items.map((item, i) => <li key={i}>item</li>)}
  </ul>


/**
  The above code should work fine, except for one problem.
  When compiling <ShowList/>,
  React-DOM renders <MyItems> before useEffect (or componentDid...) is called.
  And since `items={movies}`, 'props.items' is 'undefined' at that point.
  Thus the error message 'Cannot read property map of undefined'
 */

As a way to tackle this problem, @taggon gave a solution (see first anwser or link).

Solution: Set an initial/default value.
In our example, we can avoid items being 'undefined' by declaring a default value of an empty array.

Why? This allows React-DOM to render an empty list initially.
And when the useEffect or componentDid... method is executed, the component is re-rendered with a populated list of items.

// Let's update our 'other' component
// destructure the `items` and initialize it as an array

const MyItems = ({items = []}) =>
  <ul>
    {items.map((item, i) => <li key={i}>item</li>)}
  </ul>

Yes, python strings are immutable and any modification will result in creating a new string. This is how it's mostly done.

So, go ahead with it.

Perl solutions:

quick and dirty:

perl -lpe 'print "Project_Name=sowstest" if $. == 8' file

• -l strips newlines and adds them back in, eliminating the need for "\n"
  
• -p loops over the input file, printing every line
  
• -e executes the code in single quotes
  

$. is the line number

equivalent to @glenn's awk solution, using named arguments:

perl -slpe 'print $s if $. == $n' -- -n=8 -s="Project_Name=sowstest" file

• -s enables a rudimentary argument parser
  
• -- prevents -n and -s from being parsed by the standard perl argument parser
  

positional command arguments:

perl -lpe 'BEGIN{$n=shift; $s=shift}; print $s if $. == $n' 8 "Project_Name=sowstest" file

environment variables:

setenv n 8 ; setenv s "Project_Name=sowstest"
echo $n ; echo $s
perl -slpe 'print $ENV{s} if $. == $ENV{n}' file

ENV is the hash which contains all environment variables

Getopt to parse arguments into hash %o:

perl -MGetopt::Std -lpe 'BEGIN{getopt("ns",\%o)}; print $o{s} if $. == $o{n}' -- -n 8 -s "Project_Name=sowstest" file

Getopt::Long and longer option names

perl -MGetopt::Long -lpe 'BEGIN{GetOptions(\%o,"line=i","string=s")}; print $o{string} if $. == $o{line}' -- --line 8 --string "Project_Name=sowstest" file

Getopt is the recommended standard-library solution.
This may be overkill for one-line perl scripts, but it can be done

If those tables are empty, you have not initialized your timezone tables. According to link above you can use mysql_tzinfo_to_sql program to load the Time Zone Tables. Please try this

shell> mysql_tzinfo_to_sql /usr/share/zoneinfo

or if not working read more: http://dev.mysql.com/doc/refman/5.5/en/mysql-tzinfo-to-sql.html

Just write the "include" command :

import os

def include(filename):
    if os.path.exists(filename): 
        execfile(filename)


include('myfile.py')

@Deleet :

@bfieck remark is correct, for python 2 and 3 compatibility, you need either :

Python 2 and 3: alternative 1

from past.builtins import execfile

execfile('myfile.py')

Python 2 and 3: alternative 2

exec(compile(open('myfile.py').read()))

As @Rajib pointed out, You can't access your env variables using config('myVariable')

1. You have to add the variable to .env file first.
2. Add the variable to some config file in config directory. I usually add to config/app.php
3. Once done, will access them like Config::get('fileWhichContainsVariable.Variable'); using the Config Facade

Probably You will have to clear config cache using php artisan config:clear AND you will also have to restart server.

If you have password for your dB then

mysql -u <username> -p <DBName> < yourfile.sql

If number is separated by "." and decimals by "," (1.200.000,00) in calling gsub you must set fixed=TRUE as.numeric(gsub(".","",y,fixed=TRUE))

If you're not only seeking for a number but also hex or uuid it's worth mentioning that the SecureRandom module found its way from ActiveSupport to the ruby core in 1.9.2+. So without the need for a full blown framework:

require 'securerandom'

p SecureRandom.random_number(100) #=> 15
p SecureRandom.random_number(100) #=> 88

p SecureRandom.random_number #=> 0.596506046187744
p SecureRandom.random_number #=> 0.350621695741409

p SecureRandom.hex #=> "eb693ec8252cd630102fd0d0fb7c3485"

It's documented here: Ruby 1.9.3 - Module: SecureRandom (lib/securerandom.rb)

I tested a few solutions and one I came up with and found the one I came up with to be the fastest so I thought I would share it.

import itertools
import sys

def windowed(l, stride):
    return zip(*[itertools.islice(l, i, sys.maxsize) for i in range(stride)])

Call $watch with true as the third argument:

$scope.$watch('form', function(newVal, oldVal){
    console.log('changed');
}, true);

By default when comparing two complex objects in JavaScript, they will be checked for "reference" equality, which asks if the two objects refer to the same thing, rather than "value" equality, which checks if the values of all the properties of those objects are equal.

Per the Angular documentation, the third parameter is for objectEquality:

When objectEquality == true, inequality of the watchExpression is determined according to the angular.equals function. To save the value of the object for later comparison, the angular.copy function is used. This therefore means that watching complex objects will have adverse memory and performance implications.

You'll need to join twice:

SELECT home.*, away.*, g.network, g.date_start 
FROM game AS g
INNER JOIN team AS home
  ON home.importid = g.home
INNER JOIN team AS away
  ON away.importid = g.away
ORDER BY g.date_start DESC 
LIMIT 7

Unfortunately, not really implemented in ES6. You have this feature with OrderedMap.sort() from ImmutableJS or _.sortBy() from Lodash.

Problem I faced maybe it will help some one, I was working long time where my pc and android device connected to the same WiFi network and the android device connected via the IPV4 address of the pc with opened port 8080 trought the fire wall.

ONE DAY : I installed Genymotion emulator in order to debug UI on different screens. THANKS to Genymotion/Virtualbox network configurations it ruined my WiFi adapter.

The fix was to reconfigure IPV4/TCP settings on the WiFi netwrok adapter :

Disadvantage of second approach is big repository with created loggers. This loggers do the same if root is defined and class loggers are not defined. Standard scenario on production system is using few loggers dedicated to group of class. Sorry for my English.

On Mac OS there is also XCode. http://developer.apple.com/tools/developonrailsleopard.html

If you want to be able to revoke user tokens, you can keep track of all issued tokens on your DB and check if they're valid (exist) on a session-like table. The downside is that you'll hit the DB on every request.

I haven't tried it, but i suggest the following method to allow token revocation while keeping DB hits to a minimum -

To lower the database checks rate, divide all issued JWT tokens into X groups according to some deterministic association (e.g., 10 groups by first digit of the user id).

Each JWT token will hold the group id and a timestamp created upon token creation. e.g., { "group_id": 1, "timestamp": 1551861473716 }

The server will hold all group ids in memory and each group will have a timestamp that indicates when was the last log-out event of a user belonging to that group. e.g., { "group1": 1551861473714, "group2": 1551861487293, ... }

Requests with a JWT token that have an older group timestamp, will be checked for validity (DB hit) and if valid, a new JWT token with a fresh timestamp will be issued for client's future use. If the token's group timestamp is newer, we trust the JWT (No DB hit).

So -

1. We only validate a JWT token using the DB if the token has an old group timestamp, while future requests won't get validated until someone in the user's group will log-out.
2. We use groups to limit the number of timestamp changes (say there's a user logging in and out like there's no tomorrow - will only affect limited number of users instead of everyone)
3. We limit the number of groups to limit the amount of timestamps held in memory
4. Invalidating a token is a breeze - just remove it from the session table and generate a new timestamp for the user's group.

Well if you are using Netbeans in Linux, then you should look for the tomcat-user.xml in

/home/Username/.netbeans/8.0/apache-tomcat-8.0.3.0_base/conf (its called Catalina Base and is often hidden)

instead of the apacahe installation directory.

open tomcat-user.xml inside that folder, uncomment the user and roles and add/replace the following line.

    <user username="tomcat" password="tomcat" roles="tomcat,admin,admin-gui,manager,manager-gui"/>

restart the server . That's all

requirements.txt allows the following ways of specifying a dependency on a package in a git repository as of pip 7.0:¹

[-e] git+git://git.myproject.org/SomeProject#egg=SomeProject
[-e] git+https://git.myproject.org/SomeProject#egg=SomeProject
[-e] git+ssh://git.myproject.org/SomeProject#egg=SomeProject
-e [email protected]:SomeProject#egg=SomeProject (deprecated as of Jan 2020)

For Github that means you can do (notice the omitted -e):

git+git://github.com/mozilla/elasticutils.git#egg=elasticutils

Why the extra answer?
I got somewhat confused by the -e flag in the other answers so here's my clarification:

The -e or --editable flag means that the package is installed in <venv path>/src/SomeProject and thus not in the deeply buried <venv path>/lib/pythonX.X/site-packages/SomeProject it would otherwise be placed in.²

One more solution is to use contains which will return true or false

_.contains($(".right-tree").css("background-image"), "stage1")

Hope this helps

I was trying to find a way with Redirect but failed. Redirecting onClick is simpler than we think. Just place the following basic JavaScript within your onClick function, no monkey business:

window.location.href="pagelink"

If you can do the construction in a single operation, then something like the vstack-with-fancy-indexing answer is a fine approach. But if your condition is more complicated or your rows come in on the fly, you may want to grow the array. In fact the numpythonic way to do something like this - dynamically grow an array - is to dynamically grow a list:

A = np.array([[1,2,3],[4,5,6]])
Alist = [r for r in A]
for i in range(100):
    newrow = np.arange(3)+i
    if i%5:
        Alist.append(newrow)
A = np.array(Alist)
del Alist

Lists are highly optimized for this kind of access pattern; you don't have convenient numpy multidimensional indexing while in list form, but for as long as you're appending it's hard to do better than a list of row arrays.

Just Go To *Startmenu >>Java >>Configure Java >> Security >> Edit site list >> copy and paste your Link with problem >> OK Problem fixed :)*

In my case I had to do this, because none of the suggested solutions were available:

List<SubProduct> subProducts = Model.subproduct.Cast<SubProduct>().ToList();

If this is all the object is going to store, then best literal would be

var top_brands = {
    'Adidas' : 100,
    'Nike'   : 50
    };

Then all you need is a for...in loop.

for (var key in top_brands){
    console.log(key, top_brands[key]);
    }

spark-csv is part of core Spark functionality and doesn't require a separate library. So you could just do for example

df = spark.read.format("csv").option("header", "true").load("csvfile.csv")

In scala,(this works for any format-in delimiter mention "," for csv, "\t" for tsv etc)

val df = sqlContext.read.format("com.databricks.spark.csv") .option("delimiter", ",") .load("csvfile.csv")

I can't speak to what you are trying to do specifically with the function itself, but if you don't like the regex being built every time, here are two solutions and some caveats about each.

Here is one way to do this:

function makeSortString(s) {
  if(!makeSortString.translate_re) makeSortString.translate_re = /[öäüÖÄÜ]/g;
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  return ( s.replace(makeSortString.translate_re, function(match) { 
    return translate[match]; 
  }) );
}

This will obviously make the regex a property of the function itself. The only thing you may not like about this (or you may, I guess it depends) is that the regex can now be modified outside of the function's body. So, someone could do this to modify the interally-used regex:

makeSortString.translate_re = /[a-z]/g;

So, there is that option.

One way to get a closure, and thus prevent someone from modifying the regex, would be to define this as an anonymous function assignment like this:

var makeSortString = (function() {
  var translate_re = /[öäüÖÄÜ]/g;
  return function(s) {
    var translate = {
      "ä": "a", "ö": "o", "ü": "u",
      "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
    };
    return ( s.replace(translate_re, function(match) { 
      return translate[match]; 
    }) );
  }
})();

Hopefully this is useful to you.

UPDATE: It's early and I don't know why I didn't see the obvious before, but it might also be useful to put you translate object in a closure as well:

var makeSortString = (function() {
  var translate_re = /[öäüÖÄÜ]/g;
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  return function(s) {
    return ( s.replace(translate_re, function(match) { 
      return translate[match]; 
    }) );
  }
})();

In CSS3 there is a simple but brilliant hack for that:

font-size:calc(12px + 1.5vw);

This is because the static part of calc() defines the minimum. Even though the dynamic part might shrink to something near 0.

Can do this in jQuery. Try all options .height(), .innerHeight() or .outerHeight().

$('document').ready(function() {
    $('#right_div').css({'height': $('#left_div').innerHeight()});
});

NOTE:- use tempJson variable when you want to use.

Why and when would we create a static constructor ...?

One specific reason to use a static constructor is to create a 'super enum' class. Here's a (simple, contrived) example:

public class Animals
{
    private readonly string _description;
    private readonly string _speciesBinomialName;

    public string Description { get { return _description; } }
    public string SpeciesBinomialName { get { return _speciesBinomialName; } }

    private Animals(string description, string speciesBinomialName)
    {
        _description = description;
        _speciesBinomialName = speciesBinomialName;
    }

    private static readonly Animals _dog;
    private static readonly Animals _cat;
    private static readonly Animals _boaConstrictor;

    public static Animals Dog { get { return _dog; } }
    public static Animals Cat { get { return _cat; } }
    public static Animals BoaConstrictor { get { return _boaConstrictor; } }

    static Animals()
    {
        _dog = new Animals("Man's best friend", "Canis familiaris");
        _cat = new Animals("Small, typically furry, killer", "Felis catus");
        _boaConstrictor = new Animals("Large, heavy-bodied snake", "Boa constrictor");
    }
}

You'd use it very similarly (in syntactical appearance) to any other enum:

Animals.Dog

The advantage of this over a regular enum is that you can encapsulate related info easily. One disadvantage is that you can't use these values in a switch statement (because it requires constant values).

That's impossible with just HTML and CSS, or at least wildly exotic and complicated. If you're willing to throw some javascript in, here's a solution using jQuery:

$(function() {
    $(window).resize(function() {
        var $i = $('img#image_to_resize');
        var $c = $img.parent();
        var i_ar = $i.width() / $i.height(), c_ar = $c.width() / $c.height();            
        $i.width(i_ar > c_ar ? $c.width() : $c.height() * (i_ar));
    });
    $(window).resize();
});

That will resize the image so that it will always fit inside the parent element, regardless of it's size. And as it's binded to the $(window).resize() event, when user resizes the window, the image will adjust.

This does not try to center the image in the container, that would be possible but I guess that's not what you're after.

By default, Spring beans are singletons. The problem arises when we try to wire beans of different scopes. For example, a prototype bean into a singleton. This is known as the scoped bean injection problem.

Another way to solve the problem is method injection with the @Lookup annotation.

Here is a nice article on this issue of injecting prototype beans into a singleton instance with multiple solutions.

A comment to jarijira

Well I have had many issues with .html and .empty() methods for inputs o. If the id represents an input and not another type of html selector like

or use the .val() function to manipulate.

For example: this is the proper way to manipulate input values

<textarea class="form-control" id="someInput"></textarea>

$(document).ready(function () {
     var newVal='test'
     $('#someInput').val('') //clear input value
     $('#someInput').val(newVal) //override w/ the new value
     $('#someInput').val('test2) 
     newVal= $('#someInput').val(newVal) //get input value

}

For improper, but sometimes works For example: this is the proper way to manipulate input values

<textarea class="form-control" id="someInput"></textarea>

$(document).ready(function () {
     var newVal='test'
     $('#someInput').html('') //clear input value
     $('#someInput').empty() //clear html inside of the id
     $('#someInput').html(newVal) //override the html inside of text area w/ string could be '<div>test3</div>
     really overriding with a string manipulates the value, but this is not the best practice as you do not put things besides strings or values inside of an input. 
     newVal= $('#someInput').val(newVal) //get input value

}

An issue that I had was I was using the $getJson method and I was indeed able to use .html calls to manipulate my inputs. However, whenever I had an error or fail on the getJSON I could no longer change my inputs using the .clear and .html calls. I could still return the .val(). After some experimentation and research I discovered that you should only use the .val() function to make changes to input fields.

return Task.CompletedTask; // this will make the compiler happy

For a specific column, there is an alternative with sapply

DF <- data.frame(A = letters[1:5],
             B = letters[6:10],
             C = c(2, 5, NA, 8, NA))

DF_NEW <- sapply(seq(1, nrow(DF)),
                    function(i) ifelse(is.na(DF[i,3]) ==
                                       TRUE,
                                       0,
                                       DF[i,3]))

DF[,3] <- DF_NEW
DF

If you already have a test class, but missing the JUnit library dependency, please refer to Configuring Libraries for Unit Testing documentation section. Pressing Alt+Enter on the red code should give you an intention action to add the missing jar.

However, IDEA offers much more. If you don't have a test class yet and want to create one for any of the source classes, see instructions below.

You can use the Create Test intention action by pressing Alt+Enter while standing on the name of your class inside the editor or by using Ctrl+Shift+T keyboard shortcut.

A dialog appears where you select what testing framework to use and press Fix button for the first time to add the required library jars to the module dependencies. You can also select methods to create the test stubs for.

You can find more details in the Testing help section of the on-line documentation.

I have used this code and get the solution.

AppDomain.CurrentDomain.BaseDirectory

Your test requires a ServletContext: add @WebIntegrationTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
@WebIntegrationTest
public class UserServiceImplIT

...or look here for other options: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

UPDATE In Spring Boot 1.4.x and above @WebIntegrationTest is no longer preferred. @SpringBootTest or @WebMvcTest

Here is what i can suggest. Use another variable to derive the if clause and assign it to num1.

Code:

num2 =20 if someBoolValue else num1
num1=num2

The Arrays class has versions of sort() and binarySearch() which don't require a Comparator. For example, you can use the version of Arrays.sort() which just takes an array of objects. These methods call the compareTo() method of the objects in the array.

There may be a simpler option, but you can use VLOOKUP to check if a value appears in a list (and VLOOKUP is a powerful formula to get to grips with anyway).

So for A1, you can set a conditional format using the following formula:

=NOT(ISNA(VLOOKUP(A1,$B:$B,1,FALSE)))

Copy and Paste Special > Formats to copy that conditional format to the other cells in column A.

What the above formula is doing:

• VLOOKUP is looking up the value of Cell A1 (first parameter) against the whole of column B ($B:$B), in the first column (that's the 3rd parameter, redundant here, but typically VLOOKUP looks up a table rather than a column). The last parameter, FALSE, specifies that the match must be exact rather than just the closest match.
• VLOOKUP will return #ISNA if no match is found, so the NOT(ISNA(...)) returns true for all cells which have a match in column B.

My solution:

edit: I've added even a better solution at the end, using Modern Obj-C

1.
Put names as keys in an array.
Make sure the indexes are the appropriate enums, and in the right order (otherwise exception).
note: names is a property synthesized as *_names*;

code was not checked for compilation, but I used the same technique in my app.

typedef enum {
  JSON,
  XML,
  Atom,
  RSS
} FormatType;

+ (NSArray *)names
{
    static NSMutableArray * _names = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _names = [NSMutableArray arrayWithCapacity:4];
        [_names insertObject:@"JSON" atIndex:JSON];
        [_names insertObject:@"XML" atIndex:XML];
        [_names insertObject:@"Atom" atIndex:Atom];
        [_names insertObject:@"RSS" atIndex:RSS];
    });

    return _names;
}

+ (NSString *)nameForType:(FormatType)type
{
    return [[self names] objectAtIndex:type];
}

//

2.
Using Modern Obj-C you we can use a dictionary to tie descriptions to keys in the enum.
Order DOES NOT matter.

typedef NS_ENUM(NSUInteger, UserType) {
    UserTypeParent = 0,
    UserTypeStudent = 1,
    UserTypeTutor = 2,
    UserTypeUnknown = NSUIntegerMax
};  

@property (nonatomic) UserType type;

+ (NSDictionary *)typeDisplayNames
{
    return @{@(UserTypeParent) : @"Parent",
             @(UserTypeStudent) : @"Student",
             @(UserTypeTutor) : @"Tutor",
             @(UserTypeUnknown) : @"Unknown"};
}

- (NSString *)typeDisplayName
{
    return [[self class] typeDisplayNames][@(self.type)];
}

Usage (in a class instance method):

NSLog(@"%@", [self typeDisplayName]);

You will need to link to the file relative to the file that includes eventManager.php (Page A)

Change your code from
require_once('../includes/dbconn.inc');

To
require_once('../mysite/php/includes/dbconn.inc');

You can try c#

public string ProcessMyDataItem(object myValue)
 {
  if (myValue == null)
   {
   return "0 %"";
  }
   else
  {
     if(Convert.ToInt32(myValue) < 50)
       return "0";
     else
      return myValue.ToString() + "%";
  }

 }

asp

 <div class="tooltip" style="display: none">                                                                  
      <div style="text-align: center; font-weight: normal">
   Value =<%# ProcessMyDataItem(Eval("Percentage")) %> </div>
 </div>

for /f "delims=" %%i in ("%0") do set "curpath=%%~dpi"
echo "%curpath%"

or

echo "%cd%"

The double quotes are needed if the path contains any & characters.

Another way is to use a public static field in which you store data, i.e.:

public class MyActivity extends Activity {

  public static String SharedString;
  public static SomeObject SharedObject;

//...

I also met the case to use both python2 and python3 on my Windows machine. Here's how i resolved it:

1. download python2x and python3x, installed them.
2. add C:\Python35;C:\Python35\Scripts;C:\Python27;C:\Python27\Scripts to environment variable PATH.
3. Go to C:\Python35 to rename python.exe to python3.exe, also to C:\Python27, rename python.exe to python2.exe.
4. restart your command window.
5. type python2 scriptname.py, or python3 scriptname.py in command line to switch the version you like.

Check your firewall and antivirus for permissions for Android Debugger Bridge (adb.exe).

Swiss Army Knife: GroupBy.describe

Returns count, mean, std, and other useful statistics per-group.

df.groupby(['A', 'B'])['C'].describe()

           count  mean   std   min   25%   50%   75%   max
A   B                                                     
bar one      1.0  0.40   NaN  0.40  0.40  0.40  0.40  0.40
    three    1.0  2.24   NaN  2.24  2.24  2.24  2.24  2.24
    two      1.0 -0.98   NaN -0.98 -0.98 -0.98 -0.98 -0.98
foo one      2.0  1.36  0.58  0.95  1.15  1.36  1.56  1.76
    three    1.0 -0.15   NaN -0.15 -0.15 -0.15 -0.15 -0.15
    two      2.0  1.42  0.63  0.98  1.20  1.42  1.65  1.87

To get specific statistics, just select them,

df.groupby(['A', 'B'])['C'].describe()[['count', 'mean']]

           count      mean
A   B                     
bar one      1.0  0.400157
    three    1.0  2.240893
    two      1.0 -0.977278
foo one      2.0  1.357070
    three    1.0 -0.151357
    two      2.0  1.423148

describe works for multiple columns (change ['C'] to ['C', 'D']—or remove it altogether—and see what happens, the result is a MultiIndexed columned dataframe).

You also get different statistics for string data. Here's an example,

df2 = df.assign(D=list('aaabbccc')).sample(n=100, replace=True)

with pd.option_context('precision', 2):
    display(df2.groupby(['A', 'B'])
               .describe(include='all')

pandas >= 1.1: DataFrame.value_counts

This is available from pandas 1.1 if you just want to capture the size of every group, this cuts out the GroupBy and is faster.

df.value_counts(subset=['col1', 'col2'])

Minimal Example

# Setup
np.random.seed(0)
df = pd.DataFrame({'A' : ['foo', 'bar', 'foo', 'bar',
                          'foo', 'bar', 'foo', 'foo'],
                   'B' : ['one', 'one', 'two', 'three',
                          'two', 'two', 'one', 'three'],
                   'C' : np.random.randn(8),
                   'D' : np.random.randn(8)})

df.value_counts(['A', 'B']) 

A    B    
foo  two      2
     one      2
     three    1
bar  two      1
     three    1
     one      1

Edit the tty configuration in /etc/init/tty*.conf with a shellscript as a parameter :

(...)
exec /sbin/getty -n -l  theInputScript.sh -8 38400 tty1
(...)

This is assuming that we're editing tty1 and the script that reads input is theInputScript.sh.

A word of warning this script is run as root, so when you are inputing stuff to it you have root priviliges. Also append a path to the location of the script.

Important: the script when it finishes, has to invoke the /sbin/login otherwise you wont be able to login in the terminal.

The name open addressing refers to the fact that the location ("address") of the element is not determined by its hash value. (This method is also called closed hashing).

In separate chaining, each bucket is independent, and has some sort of ADT (list, binary search trees, etc) of entries with the same index. In a good hash table, each bucket has zero or one entries, because we need operations of order O(1) for insert, search, etc.

This is a example of separate chaining using C++ with a simple hash function using mod operator (clearly, a bad hash function)

I have tried this query in SQL Server and this worked for me :

SELECT name FROM sys.columns WHERE OBJECT_ID = OBJECT_ID('table_name')

If you have such error when using remote oracle database, you can delete your tnsname and listener then create new config with "hostname" or ip address instead of "localhost". such as listener.ora

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
    )

tnsnames.ora

DB =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = DB)
    )
  )

It works fine for me.

git add . equals git add -A . adds files to index only from current and children folders.

git add -A adds files to index from all folders in working tree.

P.S.: information relates to Git 2.0 (2014-05-28).

if you don't want or need a typed object try:

using Newtonsoft.Json;
// ...   
dynamic json  = JsonConvert.DeserializeObject(str);

or try for a typed object try:

Foo json  = JsonConvert.DeserializeObject<Foo>(str)

The error occurs when:

$a = array(); 
$a['text1'] = array();
$a['text1']['text2'] = 'sometext';

Then

echo $a['text1']['text2'];     //Error!!

Solution

$b = $a['text1'];
echo $b['text2'];    // prints: sometext
