UIActivityViewController Example Project

Set up your storyboard with two buttons and hook them up to your view controller (see code below).

Add an image to your Assets.xcassets. I called mine "lion".

Code

import UIKit
class ViewController: UIViewController {

    // share text
    @IBAction func shareTextButton(_ sender: UIButton) {

        // text to share
        let text = "This is some text that I want to share."

        // set up activity view controller
        let textToShare = [ text ]
        let activityViewController = UIActivityViewController(activityItems: textToShare, applicationActivities: nil)
        activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash

        // exclude some activity types from the list (optional)
        activityViewController.excludedActivityTypes = [ UIActivityType.airDrop, UIActivityType.postToFacebook ]

        // present the view controller
        self.present(activityViewController, animated: true, completion: nil)

    }

    // share image
    @IBAction func shareImageButton(_ sender: UIButton) {

        // image to share
        let image = UIImage(named: "Image")

        // set up activity view controller
        let imageToShare = [ image! ]
        let activityViewController = UIActivityViewController(activityItems: imageToShare, applicationActivities: nil)
        activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash

        // exclude some activity types from the list (optional)
        activityViewController.excludedActivityTypes = [ UIActivityType.airDrop, UIActivityType.postToFacebook ]

        // present the view controller
        self.present(activityViewController, animated: true, completion: nil)
    }

}

Result

Clicking "Share some text" gives result on the left and clicking "Share an image" gives the result on the right.

Notes

• I retested this with iOS 11 and Swift 4. I had to run it a couple times in the simulator before it worked because it was timing out. This may be because my computer is slow.
• If you wish to hide some of these choices, you can do that with excludedActivityTypes as shown in the code above.
• Not including the popoverPresentationController?.sourceView line will cause your app to crash when run on an iPad.
• This does not allow you to share text or images to other apps. You probably want UIDocumentInteractionController for that.

• Add sharing to your Swift app via UIActivityViewController
• UIActivity?View?Controller from NSHipster

If you go to the folder in finder, right click and select "Get Info" you can go to the "Sharing and Permissions" section for the folder and allow "Read & Write" to "everyone"

This is what I do to make symlinks pass with this error. Also brew seems to reset the permissions on the folder also as if you hadn't altered anything

This works

String x = "22/06/2012";
String y = "25/10/2014";

String datestart = x;
String datestop = y;

//DateTimeFormatter format = DateTimeFormat.forPattern("dd/mm/yyyy");
SimpleDateFormat  format = new SimpleDateFormat("dd/mm/yyyy");

Date d1 = null;
Date d2 = null;

try {
    d1 =  format.parse(datestart);
    d2 = format.parse(datestop);

    DateTime dt1 = new DateTime(d1);
    DateTime dt2 = new DateTime(d2);

    //Period
    period = new Period (dt1,dt2);

    //calculate days
    int days = Days.daysBetween(dt1, dt2).getDays();


} catch (ParseException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Extending your code (assuming that the XML you want to send is in xmlString) :

String xmlString = "</xml>";
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpRequest = new HttpPost(this.url);
httpRequest.setHeader("Content-Type", "application/xml");
StringEntity xmlEntity = new StringEntity(xmlString);
httpRequest.setEntity(xmlEntity );
HttpResponse httpresponse = httpclient.execute(httppost);

As of maven-javadoc-plugin 3.0.0 you should have been using additionalJOption to set an additional Javadoc option, so if you would like Javadoc to disable doclint, you should add the following property.

<properties>
    ...
    <additionalJOption>-Xdoclint:none</additionalJOption>
    ...
<properties>

You should also mention the version of maven-javadoc-plugin as 3.0.0 or higher.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <version>3.0.0</version>    
</plugin>

UUID is similar in notion to port numbers in Internet. However, the difference between Bluetooth and the Internet is that, in Bluetooth, port numbers are assigned dynamically by the SDP (service discovery protocol) server during runtime where each UUID is given a port number. Other devices will ask the SDP server, who is registered under a reserved port number, about the available services on the device and it will reply with different services distinguishable from each other by being registered under different UUIDs.

Something like...

DateTime today = new DateTime();
DateTime yesterday = today.minusDays(1);

Duration duration = new Duration(yesterday, today);
System.out.println(duration.getStandardDays());
System.out.println(duration.getStandardHours());
System.out.println(duration.getStandardMinutes());

Which outputs

1
24
1440

or

System.out.println(Minutes.minutesBetween(yesterday, today).getMinutes());

Which is probably more what you're after

You'll find that in javascript, there are usually many different ways to do the same thing or find the same information. In your example, you are looking for some element that is guaranteed to always exist. window and document both fit the bill (with just a few differences).

From mozilla dev network:

addEventListener() registers a single event listener on a single target. The event target may be a single element in a document, the document itself, a window, or an XMLHttpRequest.

So as long as you can count on your "target" always being there, the only difference is what events you're listening for, so just use your favorite.

With Scala there is a nice Wrapper spoiwo

You can do it like this:

Workbook(mySheet.withColumns(
      Column(autoSized = true),
      Column(width = new Width(100, WidthUnit.Character)),
      Column(width = new Width(100, WidthUnit.Character)))
    )

I've had a similar issue with this error. In my case, I was entering the incorrect password for the Keystore.

I changed the password for the Keystore to match what I was entering (I didn't want to change the password I was entering), but it still gave the same error.

keytool -storepasswd -keystore keystore.jks

Problem was that I also needed to change the Key's password within the Keystore.

When I initially created the Keystore, the Key was created with the same password as the Keystore (I accepted this default option). So I had to also change the Key's password as follows:

keytool -keypasswd  -alias my.alias -keystore keystore.jks

Below is a simple way of accessing the response as a String using Apache HTTP Client library.

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.ResponseHandler;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.BasicResponseHandler;

//... 

HttpGet get;
HttpClient httpClient;

// initialize variables above

ResponseHandler<String> responseHandler = new BasicResponseHandler();
String responseBody = httpClient.execute(get, responseHandler);

Use java.util.PriorityQueue.

Days Class

Using the Days class with the withTimeAtStartOfDay method should work:

Days.daysBetween(start.withTimeAtStartOfDay() , end.withTimeAtStartOfDay() ).getDays() 

I just tested a couple paths using Excel 2013 on on Windows 7. I found the overall pathname limit to be 213 and the basename length to be 186. At least the error dialog for exceeding basename length is clear:

And trying to move a not-too-long basename to a too-long-pathname is also very clear:

The pathname error is deceptive, though. Quite unhelpful:

This is a lazy Microsoft restriction. There's no good reason for these arbitrary length limits, but in the end, it’s a real bug in the error dialog.

This is Android Studio suggestions:

public static boolean isEmailValid(String email) {
    return !(email == null || TextUtils.isEmpty(email)) && android.util.Patterns.EMAIL_ADDRESS.matcher(email).matches();
}

A quick note: Assume.assumeTrue(condition) ignores rest of the steps but passes the test. To fail the test, use org.junit.Assert.fail() inside the conditional statement. Works same like Assume.assumeTrue() but fails the test.

Here are examples of listing files by pattern powered by Java 7 nio globbing and Java 8 lambdas:

    try (DirectoryStream<Path> dirStream = Files.newDirectoryStream(
            Paths.get(".."), "Test?/sample*.txt")) {
        dirStream.forEach(path -> System.out.println(path));
    }

or

    PathMatcher pathMatcher = FileSystems.getDefault()
        .getPathMatcher("regex:Test./sample\\w+\\.txt");
    try (DirectoryStream<Path> dirStream = Files.newDirectoryStream(
            new File("..").toPath(), pathMatcher::matches)) {
        dirStream.forEach(path -> System.out.println(path));
    }

public class Validations {

    private Pattern regexPattern;
    private Matcher regMatcher;

    public String validateEmailAddress(String emailAddress) {

        regexPattern = Pattern.compile("^[(a-zA-Z-0-9-\\_\\+\\.)]+@[(a-z-A-z)]+\\.[(a-zA-z)]{2,3}$");
        regMatcher   = regexPattern.matcher(emailAddress);
        if(regMatcher.matches()) {
            return "Valid Email Address";
        } else {
            return "Invalid Email Address";
        }
    }

    public String validateMobileNumber(String mobileNumber) {
        regexPattern = Pattern.compile("^\\+[0-9]{2,3}+-[0-9]{10}$");
        regMatcher   = regexPattern.matcher(mobileNumber);
        if(regMatcher.matches()) {
            return "Valid Mobile Number";
        } else {
            return "Invalid Mobile Number";
        }
    }

    public static void main(String[] args) {

        String emailAddress = "[email protected]";
        String mobileNumber = "+91-9986571622";
        Validations validations = new Validations();
        System.out.println(validations.validateEmailAddress(emailAddress));
        System.out.println(validations.validateMobileNumber(mobileNumber));
    }
}

While the other answers are mostly fine, you could try another, more space-efficient, encoding method like yEnc. (yEnc wikipedia link) With yEnc also get checksum capability right "out of the box". Read and links below. Of course, because XML does not have a native yEnc type your XML schema should be updated to properly describe the encoded node.

Why: Due to the encoding strategies base64/63, uuencode et al. encodings increase the amount of data (overhead) you need to store and transfer by roughly 40% (vs. yEnc's 1-2%). Depending on what you're encoding, 40% overhead could be/become an issue.

yEnc - Wikipedia abstract: https://en.wikipedia.org/wiki/YEnc yEnc is a binary-to-text encoding scheme for transferring binary files in messages on Usenet or via e-mail. ... An additional advantage of yEnc over previous encoding methods, such as uuencode and Base64, is the inclusion of a CRC checksum to verify that the decoded file has been delivered intact. ?

I just distilled this bash function from the suggestions here:

grab() {     
  grab=$("$@")
  echo $grab
}

Then, you just do:

> grab date
Do 16. Feb 13:05:04 CET 2012
> echo $grab
Do 16. Feb 13:05:04 CET 2012

Update: an anonymous user suggested to replace echo by printf '%s\n' which has the advantage that it doesn't process options like -e in the grabbed text. So, if you expect or experience such peculiarities, consider this suggestion. Another option is to use cat <<<$grab instead.

I am not sure if I fully understand your problem but since I had similar issue recently I will try to help you out.

Vendor bundle.

You should use CommonsChunkPlugin for that. in the configuration you specify the name of the chunk (e.g. vendor), and file name that will be generated (vendor.js).

new webpack.optimize.CommonsChunkPlugin("vendor", "vendor.js", Infinity),

Now important part, you have to now specify what does it mean vendor library and you do that in an entry section. One one more item to entry list with the same name as the name of the newly declared chunk (i.e. 'vendor' in this case). The value of that entry should be the list of all the modules that you want to move to vendor bundle. in your case it should look something like:

entry: {
    app: 'entry.js',
    vendor: ['jquery', 'jquery.plugin1']
}

JQuery as global

Had the same problem and solved it with ProvidePlugin. here you are not defining global object but kind of shurtcuts to modules. i.e. you can configure it like that:

new webpack.ProvidePlugin({
    $: "jquery"
})

And now you can just use $ anywhere in your code - webpack will automatically convert that to

require('jquery')

I hope it helped. you can also look at my webpack configuration file that is here

I love webpack, but I agree that the documentation is not the nicest one in the world... but hey.. people were saying same thing about Angular documentation in the begining :)

Edit:

To have entrypoint-specific vendor chunks just use CommonsChunkPlugins multiple times:

new webpack.optimize.CommonsChunkPlugin("vendor-page1", "vendor-page1.js", Infinity),
new webpack.optimize.CommonsChunkPlugin("vendor-page2", "vendor-page2.js", Infinity),

and then declare different extenral libraries for different files:

entry: {
    page1: ['entry.js'],
    page2: ['entry2.js'],
    "vendor-page1": [
        'lodash'
    ],
    "vendor-page2": [
        'jquery'
    ]
},

If some libraries are overlapping (and for most of them) between entry points then you can extract them to common file using same plugin just with different configuration. See this example.

Okay. I finally got to the bottom of this. You need to jump through some hoops to get the PUT and DELETE verbs working correctly with IIS8. In fact if you install the release candidate of VS 2012 and create a new WEB API project you'll find that the sample PUT and DELETE methods return 404 errors out of the box.

To use the PUT and DELETE verbs with the Web API you need to edit %userprofile%\documents\iisexpress\config\applicationhost.config and add the verbs to the ExtensionlessUrl handler as follows:

Change this line:

<add name="ExtensionlessUrl-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />

to:

<add name="ExtensionlessUrl-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />

In addition to the above you should ensure WebDAV is not interfering with your requests. This can be done by commenting out the following lines from applicationhost.config.

<add name="WebDAVModule" image="%IIS_BIN%\webdav.dll" />
<add name="WebDAVModule" /> 
<add name="WebDAV" path="*" verb="PROPFIND,PROPPATCH,MKCOL,PUT,COPY,DELETE,MOVE,LOCK,UNLOCK" modules="WebDAVModule" resourceType="Unspecified" requireAccess="None" />

Also be aware that the default Web API convention is that your method name should be the same as the invoked HTTP verb. For example if you're sending an HTTP delete request your method, by default, should be named Delete.

You can activate JVM's debugging capability when starting up the java command with a special option:

java -agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=y -jar path/to/some/war/or/jar.jar

Starting up jar.jar like that on the command line will:

• put this JVM instance in the role of a server (server=y) listening on port 8000 (address=8000)
• write Listening for transport dt_socket at address: 8000 to stdout and
• then pause the application (suspend=y) until some debugger connects. The debugger acts as the client in this scenario.

Common options for selecting a debugger are:

• Eclipse Debugger: Under Run -> Debug Configurations... -> select Remote Java Application -> click the New launch configuration button. Provide an arbitrary Name for this debug configuration, Connection Type: Standard (Socket Attach) and as Connection Properties the entries Host: localhost, Port: 8000. Apply the Changes and click Debug. At the moment the Eclipse Debugger has successfully connected to the JVM, jar.jar should begin executing.
• jdb command-line tool: Start it up with jdb -connect com.sun.jdi.SocketAttach:port=8000

To prevent scrolling on modern mobile browsers you need to add the passive: false. I had been pulling my hair out getting this to work until I found this solution. I have only found this mentioned in one other place on the internet.

function preventDefault(e){_x000D_
    e.preventDefault();_x000D_
}_x000D_
_x000D_
function disableScroll(){_x000D_
    document.body.addEventListener('touchmove', preventDefault, { passive: false });_x000D_
}_x000D_
function enableScroll(){_x000D_
    document.body.removeEventListener('touchmove', preventDefault);_x000D_
}

What about using ternary operator?

<?php
 // Example usage for: Ternary Operator
 $action = (empty($_POST['action'])) ? 'default' : $_POST['action'];
?>

Which is identical to this if/else statement:

<?php
 if (empty($_POST['action'])) {
   $action = 'default';
 } else {
   $action = $_POST['action'];
 }
?>

Great thing about linux, you're still able to download the source and on most systems have all of the tools to compile the version yourself.

In order to get a python cli from xterm just by typing python, the python bin directory must be in your system path variable (Red Hat example, Suse example)

NOTE: This is mentioned in the question but restarting Visual Studio fixes the issue in most cases.

Updating Visual Studio to 'Update 2' got it working again.

Tools -> Extensions and Updates ->Visual Studio Update 2

As mentioned in the question and the link i posted therein, I'd already updated NuGet Package Manager to 3.4.4 prior to this and restarted to no avail, so I don't know if the combination of both these actions worked.

It seems strange that you would write arrays without commas (is that a MATLAB syntax?)

Have you tried going through NumPy's documentation on multi-dimensional arrays?

It seems NumPy has a "Python-like" append method to add items to a NumPy n-dimensional array:

>>> p = np.array([[1,2],[3,4]])

>>> p = np.append(p, [[5,6]], 0)

>>> p = np.append(p, [[7],[8],[9]],1)

>>> p
array([[1, 2, 7], [3, 4, 8], [5, 6, 9]])

It has also been answered already...

From the documentation for MATLAB users:

You could use a matrix constructor which takes a string in the form of a matrix MATLAB literal:

mat("1 2 3; 4 5 6")

or

matrix("[1 2 3; 4 5 6]")

Please give it a try and tell me how it goes.

The function scipy.signal.find_peaks, as its name suggests, is useful for this. But it's important to understand well its parameters width, threshold, distance and above all prominence to get a good peak extraction.

According to my tests and the documentation, the concept of prominence is "the useful concept" to keep the good peaks, and discard the noisy peaks.

What is (topographic) prominence? It is "the minimum height necessary to descend to get from the summit to any higher terrain", as it can be seen here:

The idea is:

The higher the prominence, the more "important" the peak is.

Test:

I used a (noisy) frequency-varying sinusoid on purpose because it shows many difficulties. We can see that the width parameter is not very useful here because if you set a minimum width too high, then it won't be able to track very close peaks in the high frequency part. If you set width too low, you would have many unwanted peaks in the left part of the signal. Same problem with distance. threshold only compares with the direct neighbours, which is not useful here. prominence is the one that gives the best solution. Note that you can combine many of these parameters!

Code:

import numpy as np
import matplotlib.pyplot as plt 
from scipy.signal import find_peaks

x = np.sin(2*np.pi*(2**np.linspace(2,10,1000))*np.arange(1000)/48000) + np.random.normal(0, 1, 1000) * 0.15
peaks, _ = find_peaks(x, distance=20)
peaks2, _ = find_peaks(x, prominence=1)      # BEST!
peaks3, _ = find_peaks(x, width=20)
peaks4, _ = find_peaks(x, threshold=0.4)     # Required vertical distance to its direct neighbouring samples, pretty useless
plt.subplot(2, 2, 1)
plt.plot(peaks, x[peaks], "xr"); plt.plot(x); plt.legend(['distance'])
plt.subplot(2, 2, 2)
plt.plot(peaks2, x[peaks2], "ob"); plt.plot(x); plt.legend(['prominence'])
plt.subplot(2, 2, 3)
plt.plot(peaks3, x[peaks3], "vg"); plt.plot(x); plt.legend(['width'])
plt.subplot(2, 2, 4)
plt.plot(peaks4, x[peaks4], "xk"); plt.plot(x); plt.legend(['threshold'])
plt.show()

A quick search using...

apt search Xlib.h

Turns up the package libx11-dev but you shouldn't need this for pure OpenGL programming. What tutorial are you using?

You can add Xlib.h to your system by running the following...

sudo apt install libx11-dev

For parsing command line arguments on posix systems, the standard is to use the getopt() family of library routines to handle command line arguments.

A good reference is the GNU getopt manual

Use the background-color property instead of the background property in your CSS. So your code will look like this:
.fb-icon:hover {
background: blue;
}

Unfortunately, validator.resetForm() does NOT work, in many cases.

I have a case where, if someone hits the "Submit" on a form with blank values, it should ignore the "Submit." No errors. That's easy enough. If someone puts in a partial set of values, and hits "Submit," it should flag some of the fields with errors. If, however, they wipe out those values and hit "Submit" again, it should clear the errors. In this case, for some reason, there are no elements in the "currentElements" array within the validator, so executing .resetForm() does absolutely nothing.

There are bugs posted on this.

Until such time as they fix them, you need to use Nick Craver's answer, NOT Parrots' accepted answer.

Ok here's how I fixed this

My model is a list of categories. Each category contains a list of its subcategories.
with this in mind, every time in the foreach loop, each RadioButton will have its category's ID (which is unique) as its name attribue.
And I also used Html.RadioButton instead of Html.RadioButtonFor.

Here's the final 'working' pseudo-code:

@foreach (var cat in Model.Categories)
{
  //A piece of code & html here
  @foreach (var item in cat.SubCategories)
  {
     @Html.RadioButton(item.CategoryID.ToString(), item.ID)
  }    
}

The result is:

<input name="127" type="radio" value="110">

Please note that I HAVE NOT put all these radio button groups inside a form. And I don't know if this solution will still work properly in a form.

Thanks to all of the people who helped me solve this ;)

Incidentally, if your span class is even-numbered (e.g. span8) you can add an offset class to center it – for span8 that would be offset2 (assuming the default 12-column grid), for span6 it would be offset3 and so on (basically, half the number of remaining columns if you subtract the span-number from the total number of columns in the grid).

UPDATE Bootstrap 3 renamed a lot of classes so all the span*classes should be col-md-* and the offset classes should be col-md-offset-*, assuming you're using the medium-sized responsive grid.

I created a quick demo here, hope it helps: http://codepen.io/anon/pen/BEyHd.

may its so late but the response useful for others so : Sometimes, when you don't specify a server or servlet container at the creation of the project, NetBeans fails to create a context.xml file.

1. In your project under Web Pages, create a folder called META-INF.

Do this by right mouse button clicking on Web pages, and select:

New->Other->Other->File Folder

Name the folder META-INF. Case is important, even on Windows.

1. Create a file called context.xml in the META-INF folder.

Do this by right mouse button clicking on the new META-INF folder, and select:

New->Other->XML->XML Document

Name it context (NetBeans adds the .xml) Select Well-formed Document Press Finish

1. Edit the new document (context.xml), and add the following:

   <?xml version="1.0" encoding="UTF-8"?> 
   <Context antiJARLocking="true" path="/app-name"/> 
   

Replace app-name with the name of your application.

Now your in-place deployment should work. If not, make sure that the file can be read by everyone.

The context.xml file is specific to Tomcat. For more information about that file, see the Tomcat documentation at tomcat.apache.org.

I find this approach useful:

Create click event:

$( button ).on('click', function(e) {
    let id = e.node.data.id;

    $('#myModal').modal('show', {id: id});
});

Create show.bs.modal event:

$('#myModal').on('show.bs.modal', function (e) {

     // access parsed information through relatedTarget
     console.log(e.relatedTarget.id);

});

Extra:

Make your logic inside show.bs.modal to check whether the properties are parsed, like for instance as this: id: ( e.relatedTarget.hasOwnProperty( 'id' ) ? e.relatedTarget.id : null )

I solved this error using the bellow i get it from here

ionic cordova run browser will load those native plugins that support browser platform.

You can use this syntax:

#!/bin/bash

echo " Write in your age: "
read age

if [[ "$age" -le 7 || "$age" -ge 65 ]] ; then
    echo " You can walk in for free "
elif [[ "$age" -gt 7 && "$age" -lt 65 ]] ; then
    echo " You have to pay for ticket "
fi

You have the syntax wrong; there is no need to place a period inside a double-quoted string. Instead, it should be more like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$prefix%'");

You can confirm this by printing out the string to see that it turns out identical to the first case.

Of course it's not a good idea to simply inject variables into the query string like this because of the danger of SQL injection. At the very least you should manually escape the contents of the variable with mysql_real_escape_string, which would make it look perhaps like this:

$sql = sprintf("SELECT * FROM table WHERE the_number LIKE '%s%%'",
               mysql_real_escape_string($prefix));
$query = mysql_query($sql);

Note that inside the first argument of sprintf the percent sign needs to be doubled to end up appearing once in the result.

As Davide Gualano has been told. This one

$("#myDiv").load("myScript.php?var=x&var2=y&var3=z")

use GET method for sending the request, and this one

$("#myDiv").load("myScript.php", {var:x, var2:y, var3:z})

use POST method for sending the request. But any limitation that is applied to each method (post/get) is applied to the alternative usages that has been mentioned in the question.

For example: url length limits the amount of sending data in GET method.

You can use jQuery load method to get the contents and insert into an element.

Try this:

$(document).ready(function() {
        $("#lesen").click(function() {
                $(".text").load("helloworld.txt");
    }); 
}); 

You, can also add a call back to execute something once the load process is complete

e.g:

$(document).ready(function() {
    $("#lesen").click(function() {
        $(".text").load("helloworld.txt", function(){
            alert("Done Loading");
        });
   }); 
}); 

To "remove" the 1st character point to the second character:

char mystr[] = "Nmy stringP";
char *p = mystr;
p++; /* 'N' is not in `p` */

To remove the last character replace it with a '\0'.

p[strlen(p)-1] = 0; /* 'P' is not in `p` (and it isn't in `mystr` either) */

Look at the WSGI reference implementation. You already have it in your Python libraries. It's quite simple.

Width can be set to specific column as below: By percentages:

<asp:BoundField HeaderText="UserInfo"  DataField="UserInfo"  
SortExpression="UserInfo" ItemStyle-Width="100%"></asp:BoundField>

OR

By pixel:

<asp:BoundField HeaderText="UserInfo"  DataField="UserInfo"  
SortExpression="UserInfo" ItemStyle-Width="500px"></asp:BoundField>

We can override +. If unary + is used and its argument is itself an unary + call, then increment the relevant variable in the calling environment.

`+` <- function(e1,e2){
    # if unary `+`, keep original behavior
    if(missing(e2)) {
      s_e1 <- substitute(e1)
      # if e1 (the argument of unary +) is itself an unary `+` operation
      if(length(s_e1) == 2 && 
         identical(s_e1[[1]], quote(`+`)) && 
         length(s_e1[[2]]) == 1) {
        # increment value in parent environment
        eval.parent(substitute(e1 <- e1 + 1, list(e1 = s_e1[[2]])))
      # else unary `+` should just return it's input
      } else e1
    # if binary `+`, keep original behavior
    } else .Primitive("+")(e1, e2)
}

x <- 10
++x
x
# [1] 11

other operations don't change :

x + 2
# [1] 13
x ++ 2
# [1] 13
+x
# [1] 11
x
# [1] 11

Don't do it though, as you'll slow down everything. Or do it in another environment and make sure you don't have big loops on these instructions.

You can also just do this :

`++` <- function(x) eval.parent(substitute(x <- x + 1))
a <- 1
`++`(a)
a
# [1] 2

For internal gridlines, use the tag: td For external gridlines, use the tag: table

I just want to edit this for posterity that the tags for oracle weren't added when I answered this question. My response was more applicable to MS SQL.

Merge join is the best possible as it exploits the ordering, resulting in a single pass down the tables to do the join. IF you have two tables (or covering indexes) that have their ordering the same such as a primary key and an index of a table on that key then a merge join would result if you performed that action.

Hash join is the next best, as it's usually done when one table has a small number (relatively) of items, its effectively creating a temp table with hashes for each row which is then searched continuously to create the join.

Worst case is nested loop which is order (n * m) which means there is no ordering or size to exploit and the join is simply, for each row in table x, search table y for joins to do.

I had to struggle for a little bit but I found a solution, I added

-Dsonar.coverage.exclusions=**/*.* 

and the coverage metric was cancelled from the dashboard at all, so I realized that the problem was the path I was passing, not the property. In my case the path to exclude was java/org/acme/exceptions, so I used :

`-Dsonar.coverage.exclusions=**/exceptions/**/*.*` 

and it worked, but since I don't have sub-folders it also works with

-Dsonar.coverage.exclusions=**/exceptions/*.*

This should give you a list of all the tables in your database

SELECT Distinct TABLE_NAME FROM information_schema.TABLES

So you can use it similar to your database check.

If NOT EXISTS(SELECT Distinct TABLE_NAME FROM information_schema.TABLES Where TABLE_NAME = 'Your_Table')
BEGIN
    --CREATE TABLE Your_Table
END
GO

I wrote all about tabs in vim, which gives a few interesting things you didn't ask about. To automatically indent braces, use:

:set cindent

To indent two spaces (instead of one tab of eight spaces, the vim default):

:set shiftwidth=2

To keep vim from converting eight spaces into tabs:

:set expandtab

If you ever want to change the indentation of a block of text, use < and >. I usually use this in conjunction with block-select mode (v, select a block of text, < or >).

(I'd try to talk you out of using two-space indentation, since I (and most other people) find it hard to read, but that's another discussion.)

document.querySelectorAll('data-foo')

to get list of all elements having attribute data-foo

If you want to get element with data attribute which is having some specific value e.g

<div data-foo="1"></div>
<div data-foo="2" ></div>

and I want to get div with data-foo set to "2"

document.querySelector('[data-foo="2"]')

But here comes the twist what if I want to match the data attirubte value with some variable's value like I want to get element if data-foo attribute is set to i

var i=2;

so you can dynamically select the element having specific data element using template literals

document.querySelector(`[data-foo="${i}"]`)

Note even if you don't write value in string it gets converted to string like if I write

<div data-foo=1></div>

and then inspect the element in Chrome developer tool the element will be shown as below

<div data-foo="1"></div>

You can also cross verify by writing below code in console

console.log(typeof document.querySelector(`[data-foo]="${i}"`).dataset('dataFoo'))

why I have written 'dataFoo' though the attribute is data-foo reason dataset properties are converted to camelCase properties

If the file is local as your comment about SITE_PATH suggest, it's pretty simple just execute the script and cache the result in a variable using the output control functions :

function print_xml_data_file()
{
    include(XML_DATA_FILE_DIRECTORY . 'cms/data.php');
}

function get_xml_data()
{
    ob_start();
    print_xml_data_file();
    $xml_file = ob_get_contents();
    ob_end_clean();
    return $xml_file;
}

If it's remote as lot of others said curl is the way to go. If it isn't present try socket_create or fsockopen. If nothing work... change your hosting provider.

Set the class .fill to height: 100%

.fill { 
    min-height: 100%;
    height: 100%;
}

JSFiddle

(I put a red background for #map so you can see it takes up 100% height)

Here is a more generic approach. This will allow you to string format any nullable value type. I have included the second method to allow overriding the default string value instead of using the default value for the value type.

public static class ExtensionMethods
{
    public static string ToString<T>(this Nullable<T> nullable, string format) where T : struct
    {
        return String.Format("{0:" + format + "}", nullable.GetValueOrDefault());
    }

    public static string ToString<T>(this Nullable<T> nullable, string format, string defaultValue) where T : struct
    {
        if (nullable.HasValue) {
            return String.Format("{0:" + format + "}", nullable.Value);
        }

        return defaultValue;
    }
}

Sometime some C# approach makes the life easier in Java world..:

class XLINK {
static final short PAYLOAD = 102, ACK = 103, PAYLOAD_AND_ACK = 104;
}
//Now is trivial to use it like a C# enum:
int rcv = XLINK.ACK;

Typically you must set java.library.path on the JVM's command line:

java -Djava.library.path=/path/to/my/dll -cp /my/classpath/goes/here MainClass

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

del statement does not delete an instance, it merely deletes a name.

When you do del i, you are deleting just the name i - but the instance is still bound to some other name, so it won't be Garbage-Collected.

If you want to release memory, your dataframes has to be Garbage-Collected, i.e. delete all references to them.

If you created your dateframes dynamically to list, then removing that list will trigger Garbage Collection.

>>> lst = [pd.DataFrame(), pd.DataFrame(), pd.DataFrame()]
>>> del lst     # memory is released

If you created some variables, you have to delete them all.

>>> a, b, c = pd.DataFrame(), pd.DataFrame(), pd.DataFrame()
>>> lst = [a, b, c]
>>> del a, b, c # dfs still in list
>>> del lst     # memory release now

Yes it can, abstract classes constructors are generally used for super calls for initialization events common to all the subclasses

update Hotels set Discount=30 where Hotelid >= 1 and Hotelid <= 5504

You can do it with simple if statement

To check for float

if type(a)==type(1.1)

To check for integer type

if type(a)==type(1)

The %in% operator tells you which elements are among the numers to remove:

> a <- sample (1 : 10)
> remove <- c (2, 3, 5)
> a
 [1] 10  5  2  7  1  6  3  4  8  9
> a %in% remove
 [1] FALSE  TRUE  TRUE FALSE FALSE FALSE  TRUE FALSE FALSE FALSE
> a [! a %in% remove]
 [1] 10  7  1  6  4  8  9

Note that this will silently remove incomparables (stuff like NA or Inf) as well (while it will keep duplicate values in a as long as they are not listed in remove).

• If a can contain incomparables, but remove will not, we can use match, telling it to return 0 for non-matches and incomparables (%in% is a conventient shortcut for match):

  > a <- c (a, NA, Inf)
  > a
   [1]  10   5   2   7   1   6   3   4   8   9  NA Inf
  > match (a, remove, nomatch = 0L, incomparables = 0L)
   [1] 0 3 1 0 0 0 2 0 0 0 0 0
  > a [match (a, remove, nomatch = 0L, incomparables = 0L) == 0L]
  [1]  10   7   1   6   4   8   9  NA Inf
  

  incomparables = 0 is not needed as incomparables will anyways not match, but I'd include it for the sake of readability.
  This is, btw., what setdiff does internally (but without the unique to throw away duplicates in a which are not in remove).

• If remove contains incomparables, you'll have to check for them individually, e.g.

  if (any (is.na (remove))) 
    a <- a [! is.na (a)]
  

  (This does not distinguish NA from NaN but the R manual anyways warns that one should not rely on having a difference between them)

  For Inf/ -Inf you'll have to check both sign and is.finite

It was weird that no one suggested KVM.

It is gonna provide you almost native performance and it is built-in Linux. Go and check it out.

you will feel like u are using mac only and then install Xcode there u may even choose to directly boot into the OSX GUI instead of Linux one on startup

Did you use the webpack... if yes please install

angular2-template-loader

and put it

test: /\.ts$/,
   loaders: ['awesome-typescript-loader', 'angular2-template-loader']

Regarding your question,

It is the same both 'on' or 'where' on an inner join as long as your server can get it:

select * from a inner join b on a.c = b.c

and

select * from a inner join b where a.c = b.c

The 'where' option not all interpreters know so maybe should be avoided. And of course the 'on' clause is clearer.

An instance of the Router class is actually an Observable and it returns the current path everytime it changes. This is how I do it :

export class AppComponent implements OnInit { 

currentUrl : string;

constructor(private _router : Router){
    this.currentUrl = ''
}

ngOnInit() {
    this._router.subscribe(
        currentUrl => this.currentUrl = currentUrl,
        error => console.log(error)
    );
}

isCurrentRoute(route : string) : boolean {
    return this.currentUrl === route;
 } 
}

And then in my HTML :

<a [routerLink]="['Contact']" class="item" [class.active]="isCurrentRoute('contact')">Contact</a>

Another thing use "", there is a difference between "\r\n" and '\r\n'.

You need to make sure that you add forward slash before your link to socket.io:

<script src="/socket.io/socket.io.js"></script>

Then in the view/controller just do:

var socket = io.connect()

That should solve your problem.

I think AddRange is better implemented like so:

public void AddRange(IEnumerable<T> collection)
{
    foreach (var i in collection) Items.Add(i);
    OnCollectionChanged(
        new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Reset));
}

It saves you a list copy. Also if you want to micro-optimise you could do adds for up to N items and if more than N items where added do a reset.

You are getting a table scan there, meaning that you do not have an index defined on er101_upd_date_iso, or if that column is part of an existing index, the index can't be used (possibly it is not the primary indexer column).

Adding missing indexes will help performance no end.

there are already indexs on the columns which are queried most commonly

That does not mean they are used in this query (and they probably are not).

I suggest reading Finding the Causes of Poor Performance in SQL Server by Gail Shaw, part 1 and part 2.

On OS X, to open a new Chrome window - without having to close the already open windows first - pass in the additional -n flag. Make sure to specify empty string for data-dir (necessary for newer versions of Chrome, like v50 something+).

open -na /Applications/Google\ Chrome.app/ --args --disable-web-security --user-data-dir=""

I found that using Chrome 60+ on Mac OS X Sierra, the above command no longer worked, but a slight modification does:

open -n -a /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --args --user-data-dir="/tmp/chrome_dev_sess_1" --disable-web-security

The data directory path is important. Even if you're standing in your home directory when issuing the command, you can't simply refer to a local directory. It needs to be an absolute path.

   while running:
        lenli = len(li)
        for i, elem in enumerate(li):
            thiselem = elem
            nextelem = li[(i+1)%lenli] # This line is vital

Using C++ in MS Visual Studio 2015 (14), I use:

#include <chrono>

string NowToString()
{
  chrono::system_clock::time_point p = chrono::system_clock::now();
  time_t t = chrono::system_clock::to_time_t(p);
  char str[26];
  ctime_s(str, sizeof str, &t);
  return str;
}

This is confusing. When you say "form object", do you mean "<select> element"? If not, your code won't work, so I'll assume your form variable is in fact a reference to a <select> element. Why do you want to rewrite this code? What you have has worked in all scriptable browsers since around 1996, and won't stop working any time soon. Doing it with jQuery will immediately make your code slower, more error-prone and less compatible across browsers.

Here's a function that uses your current code as a starting point and populates a <select> element from an object:

<select id="mySelect"></select>

<script type="text/javascript>

function populateSelect(select, optionsData) {
    var options = select.options, o, selected;
    options.length = 0;
    for (var i = 0, len = optionsData.length; i < len; ++i) {
        o = optionsData[i];
        selected = !!o.selected;
        options[i] = new Option(o.text, o.value, selected, selected);
    }
}

var optionsData = [
    {
        text: "Select a city / town in Sweden",
        value: ""
    },
    {
        text: "Melbourne",
        value: "Melbourne",
        selected: true
    }
];

populateSelect(document.getElementById("mySelect"), optionsData);

</script>

I found the answer here:

vim -n <file>

opens file without swapfile.

In addition:

set dir=/tmp

in .vimrc creates the swapfiles in /tmp.

This can be done as

list.Sort( (emp1,emp2)=>emp1.FirstName.CompareTo(emp2.FirstName) );

The .NET framework is casting the lambda (emp1,emp2)=>int as a Comparer<Employee>.

This has the advantage of being strongly typed.

Same problem with me I solved my problem by removing verion="v3.5" from App.config.

Before

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

  <startup>

 <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2"/>
 </startup>
 <supportedRuntime version="v3.5" />//Remove this
</configuration>

Solution

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

  <startup>

    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2"/>
  </startup>
  </configuration>

I think you should add style="background:white;" to make looks like it is writable

<input type="text" size="23" name="dateMonthly" id="dateMonthly" readonly="readonly"   style="background:white;"/>

If you want a more accurate measurement than the answer above:

set statistics time on 

-- Query 1 goes here

-- Query 2 goes here

set statistics time off

The results will be in the Messages window.

Update (2015-07-29):

By popular request, I have written a code snippet that you can use to time an entire stored procedure run, rather than its components. Although this only returns the time taken by the last run, there are additional stats returned by sys.dm_exec_procedure_stats that may also be of value:

-- Use the last_elapsed_time from sys.dm_exec_procedure_stats
-- to time an entire stored procedure.

-- Set the following variables to the name of the stored proc
-- for which which you would like run duration info
DECLARE @DbName NVARCHAR(128);
DECLARE @SchemaName SYSNAME;
DECLARE @ProcName SYSNAME=N'TestProc';

SELECT CONVERT(TIME(3),DATEADD(ms,ROUND(last_elapsed_time/1000.0,0),0)) 
       AS LastExecutionTime
FROM sys.dm_exec_procedure_stats
WHERE OBJECT_NAME(object_id,database_id)=@ProcName AND
      (OBJECT_SCHEMA_NAME(object_id,database_id)=@SchemaName OR @SchemaName IS NULL) AND
      (DB_NAME(database_id)=@DbName OR @DbName IS NULL)

This is quite an old question now, but someone may come here looking for an answer:

echo $order->id;

This should return the order id without "#".

EDIT (feb/2018)

The current way of accomplishing this is by using:

$order->get_id();

I'm thinking you could just use notepad, like this:

notepad myfile.extension

It should open in notepad.

The answer, as given, is to use format-patch but since the question was how to cherry-pick from another folder, here is a piece of code to do just that:

$ git --git-dir=../<some_other_repo>/.git \
format-patch -k -1 --stdout <commit SHA> | \
git am -3 -k

(explanation from @cong ma)

The git format-patch command creates a patch from some_other_repo's commit specified by its SHA (-1 for one single commit alone). This patch is piped to git am, which applies the patch locally (-3 means trying the three-way merge if the patch fails to apply cleanly). Hope that explains.

I found a tool "webchk” written in Python. Returns a status code for a list of urls. https://pypi.org/project/webchk/

Output looks like this:

? webchk -i ./dxieu.txt | grep '200'

https://support.dxi.eu/hc/en-gb ... 200 OK (0.389)
https://support.dxi.eu/hc/en-gb ... 200 OK (0.401)

Hope that helps!

The String#replaceAll() interprets the argument as a regular expression. The \ is an escape character in both String and regex. You need to double-escape it for regex:

string.replaceAll("\\\\", "\\\\\\\\");

But you don't necessarily need regex for this, simply because you want an exact character-by-character replacement and you don't need patterns here. So String#replace() should suffice:

string.replace("\\", "\\\\");

Update: as per the comments, you appear to want to use the string in JavaScript context. You'd perhaps better use StringEscapeUtils#escapeEcmaScript() instead to cover more characters.

On which point does HTTPURLConnection try to establish a connection to the given URL?

It's worth clarifying, there's the 'UrlConnection' instance and then there's the underlying Tcp/Ip/SSL socket connection, 2 different concepts. The 'UrlConnection' or 'HttpUrlConnection' instance is synonymous with a single HTTP page request, and is created when you call url.openConnection(). But if you do multiple url.openConnection()'s from the one 'url' instance then if you're lucky, they'll reuse the same Tcp/Ip socket and SSL handshaking stuff...which is good if you're doing lots of page requests to the same server, especially good if you're using SSL where the overhead of establishing the socket is very high.

See: HttpURLConnection implementation

Here is how to make one:

Here are some inspiration examples:

It really depends on how long the NVARCHAR is, as a few of the above (especially the ones that convert through IntXX) methods will not work for:

String s = "005780327584329067506780657065786378061754654532164953264952469215462934562914562194562149516249516294563219437859043758430587066748932647329814687194673219673294677438907385032758065763278963247982360675680570678407806473296472036454612945621946";

Something like this would

String s ="0000058757843950000120465875468465874567456745674000004000".TrimStart(new Char[] { '0' } );
// s = "58757843950000120465875468465874567456745674000004000"

DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];

for (int i = 0; i < dr_art_line_2.Rows.Count; i++)
{
    QuantityInIssueUnit_value = Convert.ToInt32(dr_art_line_2.Rows[i]["columnname"]);
    //Similarly for QuantityInIssueUnit_uom.
}

If you are using at least Java 8 you can use method runAsync from class CompletableFuture

CompletableFuture.runAsync(() -> {...});

If you need to return a result use supplyAsync instead

CompletableFuture.supplyAsync(() -> 1);

Better simplified extension function thanks to ADev

fun ImageView.setTint(@ColorRes colorRes: Int) {
    ImageViewCompat.setImageTintList(this, ColorStateList.valueOf(ContextCompat.getColor(context, colorRes)))
}

Usage:-

imageView.setTint(R.color.tintColor)

This command:

iconv -f utf-8 -t utf-8 -c file.txt

will clean up your UTF-8 file, skipping all the invalid characters.

-f is the source format
-t the target format
-c skips any invalid sequence

If you use IntelliJ IDEA, try the following:

1. From 'File', select "Invalidate Caches/ Restart" option.
2. Confirm this action by clicking the "Invalidate and Restart" button.
3. Then the IDEA will be restarted.
4. You will then find a fresh copy of your project.
5. You then need to import/ change project format to the Maven project. IDEA will show you options at the bottom right corner.
6. After this, you should be able to run your project.

There are a couple ways to do this.

First, instead of going into openssl command prompt mode, just enter everything on one command line from the Windows prompt:

E:\> openssl x509 -pubkey -noout -in cert.pem  > pubkey.pem

If for some reason, you have to use the openssl command prompt, just enter everything up to the ">". Then OpenSSL will print out the public key info to the screen. You can then copy this and paste it into a file called pubkey.pem.

openssl> x509 -pubkey -noout -in cert.pem

Output will look something like this:

GitHub has deprecated the download support and now supports 'Releases' - https://github.com/blog/1547-release-your-software. To create a release either use the GitHub UI or create an annotated tag (http:// git-scm.com/book/ch2-6.html) and add release notes to it in GitHub. You can then upload binaries, or 'assets', to each release.

Once you have some releases, the GitHub API supports getting information about them, and their assets.

curl -i \
https://api.github.com/repos/:owner/:repo/releases \
-H "Accept: application/vnd.github.manifold-preview+json"

Look for the 'download_count' entry. Theres more info at http://developer.github.com/v3/repos/releases/. This part of the API is still in the preview period ATM so it may change.

Update Nov 2013:

GitHub's releases API is now out of the preview period so the 'Accept' header is no longer needed - http://developer.github.com/changes/2013-11-04-releases-api-is-official/

It won't do any harm to continue to add the 'Accept' header though.

Here how to do it using format()

print "bin_signedDate : ", ''.join(format(x, '08b') for x in bytevector)

It is important the 08b . That means it will be a maximum of 8 leading zeros be appended to complete a byte. If you don't specify this then the format will just have a variable bit length for each converted byte.

In addition to Mathias answer.

Although not mentioned in OP, if you also need to see the Powershell specific/related internal variables, you need to use Get-Variable:

Use D. See docs for further information.

As you say, you don't need to request the file twice. Pass it from your controller to your directive. Assuming you use the directive inside the scope of the controller:

.controller('MyController', ['$scope', '$http', function($scope, $http) {
  $http.get('locations/locations.json').success(function(data) {
      $scope.locations = data;
  });
}

Then in your HTML (where you call upon the directive).
Note: locations is a reference to your controllers $scope.locations.

<div my-directive location-data="locations"></div>

And finally in your directive

...
scope: {
  locationData: '=locationData'
},
controller: ['$scope', function($scope){
  // And here you can access your data
  $scope.locationData
}]
...

This is just an outline to point you in the right direction, so it's incomplete and not tested.

redirect with query string

 $('#results').on('click', '.item', function () {
                    var NestId = $(this).data('id');
                   // var url = '@Url.Action("Details", "Artists",new { NestId = '+NestId+'  })'; 
                    var url = '@ Url.Content("~/Artists/Details?NestId =' + NestId + '")'
                    window.location.href = url; 
                })

I think you can try this:

<a th:href="${'/category/edit/' + {category.id}}">view</a>

Or if you have "idCategory" this:

<a th:href="${'/category/edit/' + {category.idCategory}}">view</a>

You can use onSelect event

 $("#date-daily").datepicker({
  onSelect: function(dateText) {
   alert($('#dp3').val());
  }
});

It is Called when the datepicker is selected. The function receives the selected date as text and the datepicker instance as parameters. this refers to the associated input field.

From your log its clear that numpy package is missing. As mention in the PyPI package:

The SciPy library depends on NumPy, which provides convenient and fast N-dimensional array manipulation.

So, try installing numpy package for python as you did with scipy.

.center {
  margin: auto;
  margin-top: 15vh;
}

Should do the trick

AffineTransform instances can be concatenated (added together). Therefore you can have a transform that combines 'shift to origin', 'rotate' and 'shift back to desired position'.

        {
            string src = string.empty;
            byte[] mergedImageData = new byte[0];

            mergedImageData = MergeTwoImageByteArrays(watermarkByteArray, backgroundImageByteArray);
            src = "data:image/png;base64," + Convert.ToBase64String(mergedImageData);
            MyImage.ImageUrl = src;
        }

        private byte[] MergeTwoImageByteArrays(byte[] imageBytes, byte[] imageBaseBytes)
        {
            byte[] mergedImageData = new byte[0];
            using (var msBase = new MemoryStream(imageBaseBytes))
            {
                System.Drawing.Image imgBase = System.Drawing.Image.FromStream(msBase);
                Graphics gBase = Graphics.FromImage(imgBase);
                using (var msInfo = new MemoryStream(imageBytes))
                {
                    System.Drawing.Image imgInfo = System.Drawing.Image.FromStream(msInfo);
                    Graphics gInfo = Graphics.FromImage(imgInfo);
                    gBase.DrawImage(imgInfo, new Point(0, 0));
                    //imgBase.Save(Server.MapPath("_____testImg.png"), ImageFormat.Png);
                    MemoryStream mergedImageStream = new MemoryStream();
                    imgBase.Save(mergedImageStream, ImageFormat.Png);
                    mergedImageData = mergedImageStream.ToArray();
                    mergedImageStream.Close();
                }
            }
            return mergedImageData;
        }

This is the perfect code for uploading and displaying image through MySQL database.

<html>
<body>
<form method="post" enctype="multipart/form-data">
<input type="file" name="image"/>
<input type="submit" name="submit" value="Upload"/>
</form>
<?php
    if(isset($_POST['submit']))
    {
     if(getimagesize($_FILES['image']['tmp_name'])==FALSE)
     {
        echo " error ";
     }
     else
     {
        $image = $_FILES['image']['tmp_name'];
        $image = addslashes(file_get_contents($image));
        saveimage($image);
     }
    }
    function saveimage($image)
    {
        $dbcon=mysqli_connect('localhost','root','','dbname');
        $qry="insert into tablename (name) values ('$image')";
        $result=mysqli_query($dbcon,$qry);
        if($result)
        {
            echo " <br/>Image uploaded.";
            header('location:urlofpage.php');
        }
        else
        {
            echo " error ";
        }
    }
?>
</body>
</html>

Wrap the <form> element inside a div container and apply css to the div instead which makes things easier.

#aDiv{width: 300px; height: 300px; margin: 0 auto;}

Here is a part of code I use to direct my server.js file to angular dist folder, which was created after npm build

// Create link to Angular build directory
var distDir = __dirname + "/dist/";
app.use(express.static(distDir));

I fixed it by changing "/dist/" to "./dist/"

You can check if the dom already exists by setting a timeout until it is already rendered in the dom.

var panelMainWrapper = document.getElementById('panelMainWrapper');
setTimeout(function waitPanelMainWrapper() {
    if (document.body.contains(panelMainWrapper)) {
        $("#panelMainWrapper").html(data).fadeIn("fast");
    } else {
        setTimeout(waitPanelMainWrapper, 10);
    }
}, 10);

To test for existence there are two methods.

a. "property" in object

This method checks the prototype chain for existence of the property.

b. object.hasOwnProperty( "property" )

This method does not go up the prototype chain to check existence of the property, it must exist in the object you are calling the method on.

var x; // variable declared in global scope and now exists

"x" in window; // true
window.hasOwnProperty( "x" ); //true

If we were testing using the following expression then it would return false

typeof x !== 'undefined'; // false

//Create our own namespaces for the output
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();

//Add an empty namespace and empty value
ns.Add("", "");

//Create the serializer
XmlSerializer slz = new XmlSerializer(someType);

//Serialize the object with our own namespaces (notice the overload)
slz.Serialize(myXmlTextWriter, someObject, ns)

For Swift use this...

UIGraphicsBeginImageContext(self.view.frame.size)
UIImage(named: "ImageName.png")?.draw(in: self.view.bounds)

if let image = UIGraphicsGetImageFromCurrentImageContext(){
    UIGraphicsEndImageContext()
    self.view.backgroundColor = UIColor(patternImage: image)
}else{
    UIGraphicsEndImageContext()
    debugPrint("Image not available")
 }

This is a stupid/hacky way

print count,    
print conv

<ProgressBar
android:id="@+id/loading_spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminateTintMode="src_atop"
android:indeterminateTint="@color/your_customized_color"
android:layout_gravity="center" />

The effect looks like this:

If you are using this form of the branch command (with start point), it does not matter where your HEAD is.

What you are doing:

git checkout dev
git branch test 07aeec983bfc17c25f0b0a7c1d47da8e35df7af8

• First, you set your HEAD to the branch dev,

• Second, you start a new branch on commit 07aeec98. There is no bb.txt at this commit (according to your github repo).

If you want to start a new branch at the location you have just checked out, you can either run branch with no start point:

git branch test

or as other have answered, branch and checkout there in one operation:

git checkout -b test

I think that you might be confused by that fact that 07aeec98 is part of the branch dev. It is true that this commit is an ancestor of dev, its changes are needed to reach the latest commit in dev. However, they are other commits that are needed to reach the latest dev, and these are not necessarily in the history of 07aeec98.

8480e8ae (where you added bb.txt) is for example not in the history of 07aeec98. If you branch from 07aeec98, you won't get the changes introduced by 8480e8ae.

In other words: if you merge branch A and branch B into branch C, then create a new branch on a commit of A, you won't get the changes introduced in B.

Same here, you had two parallel branches master and dev, which you merged in dev. Branching out from a commit of master (older than the merge) won't provide you with the changes of dev.

If you want to permanently integrate new changes from master into your feature branches, you should merge master into them and go on. This will create merge commits in your feature branches, though.

If you have not published your feature branches, you can also rebase them on the updated master: git rebase master featureA. Be prepared to solve possible conflicts.

If you want a workflow where you can work on feature branches free of merge commits and still integrate with newer changes in master, I recommend the following:

• base every new feature branch on a commit of master
• create a dev branch on a commit of master
• when you need to see how your feature branch integrates with new changes in master, merge both master and the feature branch into dev.

Do not commit into dev directly, use it only for merging other branches.

For example, if you are working on feature A and B:

a---b---c---d---e---f---g -master
    \       \
     \       \-x -featureB
      \
       \-j---k -featureA

Merge branches into a dev branch to check if they work well with the new master:

a---b---c---d---e---f---g -master
    \       \            \
     \       \            \--x'---k' -dev
      \       \             /    /   
       \       \-x----------    /    -featureB
        \                      /
         \-j---k--------------- -featureA

You can continue working on your feature branches, and keep merging in new changes from both master and feature branches into dev regularly.

a---b---c---d---e---f---g---h---i----- -master
    \       \            \            \
     \       \            \--x'---k'---i'---l' -dev
      \       \             /    /         /
       \       \-x----------    /         /  -featureB
        \                      /         /  
         \-j---k-----------------l------ -featureA

When it is time to integrate the new features, merge the feature branches (not dev!) into master.

A very readable example from another post on similar topic:

var args = [ 'p0', 'p1', 'p2' ];

function call_me (param0, param1, param2 ) {
    // ...
}

// Calling the function using the array with apply()
call_me.apply(this, args);

And here a link to the original post that I personally liked for its readability

If you need to use in Fragment you should use

private Context context;

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        this.context = context;
    }


    ((MainActivity)context).runOnUiThread(new Runnable() {
        public void run() {
            Log.d("UI thread", "I am the UI thread");
        }
    });

instead of

getActivity().runOnUiThread(new Runnable() {
    public void run() {
        Log.d("UI thread", "I am the UI thread");
    }
});

Because There will be null pointer exception in some situation like pager fragment

declare @OrderByCmd  nvarchar(2000)
declare @OrderByName nvarchar(100)
declare @OrderByCity nvarchar(100)
set @OrderByName='Name'    
set @OrderByCity='city'
set @OrderByCmd= 'select * from customer Order By '+@OrderByName+','+@OrderByCity+''
EXECUTE sp_executesql @OrderByCmd 

I think what you really want is an ArrayList or Vector. Arrays in Java are not like those in Javascript.

<?php
if(isset($_POST['btnSave'])){
    $j = 0; //Variable for indexing uploaded image 

    $file_name_all="";

    $target_path = "uploads/"; //Declaring Path for uploaded images

    //loop to get individual element from the array
    for ($i = 0; $i < count($_FILES['file']['name']); $i++) {

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable
        $basename=basename($_FILES['file']['name'][$i]);
        //echo"hi its base name".$basename;
        $target_path = $target_path .$basename;//set the target path with a new name of image
        $j = $j + 1;//increment the number of uploaded images according to the files in array       

        if (($_FILES["file"]["size"][$i] < (1024*1024)) //Approx. 100kb files can be uploaded.
        && in_array($file_extension, $validextensions)) {
            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder
                echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
                /***********************************************/

                $file_name_all.=$target_path."*";  
                $filepath = rtrim($file_name_all, '*');  
                //echo"<img src=".$filepath."   >";          

                /*************************************************/
            } else {//if file was not moved.
                echo $j. ').<span id="error">please try again!.</span><br/><br/>';
            }
        } else {//if file size and file type was incorrect.
            echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
        }
    }
    $qry="INSERT INTO `eb_re_about_us`(`er_abt_us_id`, `er_cli_id`, `er_cli_abt_info`, `er_cli_abt_img`) VALUES (NULL,'$b1','$b5','$filepath')";


    $res = mysql_query($qry,$conn); 
    if($res)
        echo "<br/><br/>Client contact Person Information Details Saved successfully";
        //header("location: nextaddclient.php");
        //exit();
    else
        echo "<br/><br/>Client contact Person Information Details not saved successfully";

}
?>

Here $file_name_all And $filepath get 1 uplode file name 2 time?

Try this. Works for me.

.background {
    background-image: url(images/images.jpg);
    display: block;
    position: relative;
}

.background::after {
    content: "";
    background: rgba(45, 88, 35, 0.7);
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    z-index: 1;
}

.background > * {
    z-index: 10;
}

you can put your json in a parameter and send it instead of put only your json in header:

$post_string= 'json_param=' . json_encode($data);

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $post_string);
curl_setopt($curl, CURLOPT_URL, 'http://webservice.local/');  // Set the url path we want to call

//execute post
$result = curl_exec($curl);

//see the results
$json=json_decode($result,true);
curl_close($curl);
print_r($json);

on the service side you can get your json string as a parameter:

$json_string = $_POST['json_param'];
$obj = json_decode($json_string);

then you can use your converted data as object.

I don't think there is a way to ignore adding DEFINERs to the dump. But there are ways to remove them after the dump file is created.

1. Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost with an empty string ""

2. Edit the dump (or pipe the output) using perl:

   perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql
   

3. Pipe the output through sed:

   mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql
   

Does the column allow null?

Seems to work. Just tested with phpMyAdmin, the column is of type int that allows nulls:

INSERT INTO `database`.`table` (`column`) VALUES (NULL);

Issue the following command to reseed mytable to start at 1:

DBCC CHECKIDENT (mytable, RESEED, 0)

Read about it in the Books on Line (BOL, SQL help). Also be careful that you don't have records higher than the seed you are setting.

In a couple of lines, Cygwin and PowerShell are different tools however if you have Cygwin installed you can run the Cygwin executables within a PowerShell session. I've gotten so used to PowerShell that now I no longer use grep, sort, awk, etc. There are pretty much built-in alternatives in PowerShell, and if not you can find a cmdlet out there.

The main tool I find myself using is ssh.exe, but within a PowerShell session.

It works great.

Just so I don't lose my answer that works:

1. Select the cell to copy
2. Select the final cell in the column
3. Press CTRL+D

You can use the subprocess package with the code as below:

import subprocess
cmdCommand = "python test.py"   #specify your cmd command
process = subprocess.Popen(cmdCommand.split(), stdout=subprocess.PIPE)
output, error = process.communicate()
print output

EDIT: After your comments, I understand that you want to pass variable through your form.

You can do this using hidden field:

<input type='hidden' name='var' value='<?php echo "$var";?>'/> 

In PHP action File:

<?php 
   if(isset($_POST['var'])) $var=$_POST['var'];
?>

Or using sessions: In your first page:

 $_SESSION['var']=$var;

start_session(); should be placed at the beginning of your php page.

In PHP action File:

if(isset($_SESSION['var'])) $var=$_SESSION['var'];

First Answer:

You can also use $GLOBALS :

if (isset($_POST['save_exit']))
{

   echo $GLOBALS['var']; 

}

Check this documentation for more informations.

The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

Try this:

#include <stdio.h>
#include <unistd.h>
#include <string.h> /* for strncpy */

#include <sys/types.h>
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <netinet/in.h>
#include <net/if.h>
#include <arpa/inet.h>

int
main()
{
 int fd;
 struct ifreq ifr;

 fd = socket(AF_INET, SOCK_DGRAM, 0);

 /* I want to get an IPv4 IP address */
 ifr.ifr_addr.sa_family = AF_INET;

 /* I want IP address attached to "eth0" */
 strncpy(ifr.ifr_name, "eth0", IFNAMSIZ-1);

 ioctl(fd, SIOCGIFADDR, &ifr);

 close(fd);

 /* display result */
 printf("%s\n", inet_ntoa(((struct sockaddr_in *)&ifr.ifr_addr)->sin_addr));

 return 0;
}

The code sample is taken from here.

The value attribute is used to determine the rendered label of a submit input.

<input type="submit" class="like" value="Like" />

Note that if the control is successful (this one won't be as it has no name) this will also be the submitted value for it.

To have a different submitted value and label you need to use a button element, in which the textNode inside the element determines the label. You can include other elements (including <img> here).

<button type="submit" class="like" name="foo" value="bar">Like</button>

Note that support for <button> is dodgy in older versions of Internet Explorer.

As david mentions, DIVs do wrap words by default.

If you are referring to really long strings of text without spaces, what I do is process the string server-side and insert empty spans:

thisIsAreallyLongStringThatIWantTo<span></span>BreakToFitInsideAGivenSpace

It's not exact as there are issues with font-sizing and such. The span option works if the container is variable in size. If it's a fixed width container, you could just go ahead and insert line breaks.

#!/bin/bash
while getopts "abc:d:" flag
do
  case $flag in
    a) echo "[getopts:$OPTIND]==> -$flag";;
    b) echo "[getopts:$OPTIND]==> -$flag";;
    c) echo "[getopts:$OPTIND]==> -$flag $OPTARG";;
    d) echo "[getopts:$OPTIND]==> -$flag $OPTARG";;
  esac
done

shift $((OPTIND-1))
echo "[otheropts]==> $@"

exit

.

#!/bin/bash
until [ -z "$1" ]; do
  case $1 in
    "--dlong")
      shift
      if [ "${1:1:0}" != "-" ]
      then
        echo "==> dlong $1"
        shift
      fi;;
    *) echo "==> other $1"; shift;;
  esac
done
exit

Here example on plain JS:

document.querySelector('#myDiv').addEventListener('keyup', function (e) {_x000D_
  console.log(e.key)_x000D_
})

#myDiv {_x000D_
  outline: none;_x000D_
}

<div _x000D_
  id="myDiv"_x000D_
  tabindex="0"_x000D_
>_x000D_
  Press me and start typing_x000D_
</div>

Personally:

for _ in range(50):
    print "Some thing"

if you don't need i. If you use Python < 3 and you want to repeat the loop a lot of times, use xrange as there is no need to generate the whole list beforehand.

I don't think you can. I always go with height and width.

textarea{
width:400px;
height:100px;
}

the nice thing about doing it the CSS way is that you can completely style it up. Now you can add things like:

textarea{
width:400px;
height:100px;
border:1px solid #000000;
background-color:#CCCCCC;

I had this problem when I added Swift source code to an existing ObjC static framework (dynamic framework with Mach-O type "Static Library").

The fix was setting CLANG_ENABLE_MODULES ("Enable Modules" in build settings) to YES

You JSON is not a valid string as P. Galbraith has told you above.

and here is the solution for it.

<?php 
$json_url = "http://api.testmagazine.com/test.php?type=menu";
$json = file_get_contents($json_url);
$json=str_replace('},

]',"}

]",$json);
$data = json_decode($json);

echo "<pre>";
print_r($data);
echo "</pre>";
?>

Use this code it will work for you.

Is this what you are looking for:

myListBox.DataSource = MyList;

At first,

You should know that destroy() is correct method for removing an entity directly via object or model and delete() can only be called in query builder.

In your case, You have not checked if record exists in database or not. Record can only be deleted if exists.

So, You can do it like follows.

$user = User::find($id);
    if($user){
        $destroy = User::destroy(2);
    }

The value or $destroy above will be 0 or 1 on fail or success respectively. So, you can alter the $data array like:

if ($destroy){

    $data=[
        'status'=>'1',
        'msg'=>'success'
    ];

}else{

    $data=[
        'status'=>'0',
        'msg'=>'fail'
    ];

}

Hope, you understand.

Wrap text in a span and use jquery width()

i would recommend using the following code.

table.ajax.reload(null, false); 

The reason for this, user paging will not be reset on reload.
Example:

<button id='refresh'> Refresh </button>

<script>
    $(document).ready(function() {

        table = $("#my-datatable").DataTable();
        $("#refresh").on("click", function () { 
         table.ajax.reload(null, false); 
        });

   });
</script>

Try

str.match(/<b>(.*?)<\/b>/g);

My use case is that I'm on a metered account. Data transfer is limited on weekdays, Mon - Fri, from 6am - 6pm. I am using bandwidth limiting, but somehow, data still slips through, about 1GB per day!

I strongly suspected it's sickrage or sickbeard, doing a high amount of searches. My download machine is called "download." The following was my solution, using the above,for starting, and stopping the download VM, using KVM:

# Stop download Mon-Fri, 6am
0 6 * * 1,2,3,4,5 root          virsh shutdown download
# Start download Mon-Fri, 6pm
0 18 * * 1,2,3,4,5 root         virsh start download

I think this is correct, and hope it helps someone else too.

Do something every one second

Timer timer = new Timer();
timer.schedule(new TimerTask() {
    @Override
    public void run() {
        //code
    }
}, 0, 1000);

A different solution:

An easy inline solution that wont crash if your array is too short

[0,1,2,3,4,5].enumerated().compactMap{ $0.offset < 3 ? $0.element : nil }

But works fine with this.

[0,1,2,3,4,5].enumerated().compactMap{ $0.offset < 1000 ? $0.element : nil }

Usually this would crash if you did this:

[0,1,2,3,4,5].prefix(upTo: 1000) // THIS CRASHES

[0,1,2,3,4,5].prefix(1000) // THIS DOESNT

If you are using CMS like Drupal or Wordpress - just install jQuery Update module and error no longer persists.

If you want to play with the thread stack size, you'll want to look at the -Xss option on the Hotspot JVM. It may be something different on non Hotspot VM's since the -X parameters to the JVM are distribution specific, IIRC.

On Hotspot, this looks like java -Xss16M if you want to make the size 16 megs.

Type java -X -help if you want to see all of the distribution specific JVM parameters you can pass in. I am not sure if this works the same on other JVMs, but it prints all of Hotspot specific parameters.

For what it's worth - I would recommend limiting your use of recursive methods in Java. It's not too great at optimizing them - for one the JVM doesn't support tail recursion (see Does the JVM prevent tail call optimizations?). Try refactoring your factorial code above to use a while loop instead of recursive method calls.

Try use it:

Uri uri =  Uri.fromFile(entry);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
String mime = "*/*";
MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton();
if (mimeTypeMap.hasExtension(
    mimeTypeMap.getFileExtensionFromUrl(uri.toString())))
    mime = mimeTypeMap.getMimeTypeFromExtension(
        mimeTypeMap.getFileExtensionFromUrl(uri.toString()));
intent.setDataAndType(uri,mime);
startActivity(intent);

If you only need to exclude out enter, escape and spacebar keys, you can do the following:

$("#text1").keyup(function(event) {
if (event.keyCode != '13' && event.keyCode != '27' && event.keyCode != '32') {
     alert('test');
   }
});

See it actions here.

You can refer to the complete list of keycode here for your further modification.

If you want like Cells(Rows.Count, 1).End(xlUp).Row , you can do it.

just use the following code:

using Excel = Microsoft.Office.Interop.Excel;

string xlBk = @"D:\Test.xlsx";
Excel.Application xlApp;
Excel.Workbook xlWb;
Excel.Worksheet xlWs;

Excel.Range rng;
int iLast;

xlApp = new Excel.Application();
xlWb = xlApp.Workbooks.Open(xlBk, 0, true, 5, "", "", true, 
Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);

xlWs = (Excel.Worksheet)xlWb.Worksheets.get_Item(1);

iLast = xlWs.Rows.Count;
rng = (Excel.Range)xlWs.Cells[iLast, 1];
iLast = rng.get_End(Excel.XlDirection.xlUp).Row;

int a = fork(); 

Creates a duplicate process "clone?", which shares the execution stack. The difference between the parent and the child is the return value of the function.

The child getting 0 returned, and the parent getting the new pid.

Each time the addresses and the values of the stack variables are copied. The execution continues at the point it already got to in the code.

At each fork, only one value is modified - the return value from fork.

int(n**0.5) is the floor value of sqrt(n) which you confused with power 2 of n (n**2). If n is not prime, there must be two numbers 1 < i <= j < n such that: i * j = n.

Now, since sqrt(n) * sqrt(n) = n assuming one of i,j is bigger than (or equals to) sqrt(n) - it means that the other one has to be smaller than (or equals to) sqrt(n).

Since that is the case, it's good enough to iterate the integer numbers in the range [2, sqrt(n)]. And that's exactly what the code that was posted is doing.

If you want to come out as a real smartass, use the following one-liner function:

import re
def is_prime(n):    
    return not re.match(r'^1?$|^(11+?)\1+$',n*'1')

I encountered this error when running my Android app on my home WiFi, then trying to run it on different WiFi without closing my simulator.

Simply closing the simulator and re-launching the app worked for me!

The w and h variables in img.onload function are not in the same scope with those in the getMeta() function. One way to do it, is as follows:

Fiddle: http://jsfiddle.net/ppanagi/28UES/2/

function getMeta(varA, varB) {
    if (typeof varB !== 'undefined') {
       alert(varA + ' width ' + varB + ' height');
    } else {
       var img = new Image();
       img.src = varA;
       img.onload = getMeta(this.width, this.height);
    }
}


getMeta("http://snook.ca/files/mootools_83_snookca.png");

        $('#tagsname').html('You selected: ' + ui.item.value);
    });
});

I know this is an old question, but I shall post my answer for posterity...

It depends on the system that you are building and the particular business rules in place.

I am building a moderate to large scale CRM in MongoDb, C# (Backend API), and Angular (Frontend web app) and found ObjectId utterly terrible for use in Angular Routing for selecting particular entities. Same with API Controller routing.

The suggestion above worked perfectly for my project.

db.contacts.insert({
 "id":db.contacts.find().Count()+1,
 "name":"John Doe",
 "emails":[
    "[email protected]",
    "[email protected]"
 ],
 "phone":"555111322",
 "status":"Active"
});

The reason it is perfect for my case, but not all cases is that as the above comment states, if you delete 3 records from the collection, you will get collisions.

My business rules state that due to our in house SLA's, we are not allowed to delete correspondence data or clients records for longer than the potential lifespan of the application I'm writing, and therefor, I simply mark records with an enum "Status" which is either "Active" or "Deleted". You can delete something from the UI, and it will say "Contact has been deleted" but all the application has done is change the status of the contact to "Deleted" and when the app calls the respository for a list of contacts, I filter out deleted records before pushing the data to the client app.

Therefore, db.collection.find().count() + 1 is a perfect solution for me...

It won't work for everyone, but if you will not be deleting data, it works fine.

Use enumerate() like so:

def draw_menu(options, selected_index):
    for counter, option in enumerate(options):
        if counter == selected_index:
            print " [*] %s" % option
        else:
            print " [ ] %s" % option    

options = ['Option 0', 'Option 1', 'Option 2', 'Option 3']
draw_menu(options, 2)

Note: You can optionally put parenthesis around counter, option, like (counter, option), if you want, but they're extraneous and not normally included.

How to get the last N rows of a pandas DataFrame?

If you are slicing by position, __getitem__ (i.e., slicing with[]) works well, and is the most succinct solution I've found for this problem.

pd.__version__
# '0.24.2'

df = pd.DataFrame({'A': list('aaabbbbc'), 'B': np.arange(1, 9)})
df

   A  B
0  a  1
1  a  2
2  a  3
3  b  4
4  b  5
5  b  6
6  b  7
7  c  8

df[-3:]

   A  B
5  b  6
6  b  7
7  c  8

This is the same as calling df.iloc[-3:], for instance (iloc internally delegates to __getitem__).

As an aside, if you want to find the last N rows for each group, use groupby and GroupBy.tail:

df.groupby('A').tail(2)

   A  B
1  a  2
2  a  3
5  b  6
6  b  7
7  c  8

//Suppose function not taking any parameter means just add the GetAlterConfirmation(function(result) {});
GetAlterConfirmation('test','messageText',function(result) {
                        alert(result);
    }); //Function into document load or any other click event.


function GetAlterConfirmation(titleText, messageText, _callback){
         bootbox.confirm({
                    title: titleText,
                    message: messageText,
                    buttons: {
                        cancel: {
                            label: '<i class="fa fa-times"></i> Cancel'
                        },
                        confirm: {
                            label: '<i class="fa fa-check"></i> Confirm'
                        }
                    },
                    callback: function (result) {
                        return _callback(result); 
                    }
                });

We need to execute the following command:

mongoimport --host=127.0.0.1 -d database_name -c collection_name --type csv --file csv_location --headerline

-d is database name

-c is collection name

--headerline If using --type csv or --type tsv, uses the first line as field names. Otherwise, mongoimport will import the first line as a distinct document.

For more information: mongoimport

Here's my solution:

Put all the counters in a dictionary:

{% set counter = {
    'counter1': 0,
    'counter2': 0,
    'etc': 0,
    } %}

Define a macro to increment them easily:

{% macro increment(dct, key, inc=1)%}
    {% if dct.update({key: dct[key] + inc}) %} {% endif %}
{% endmacro %}

Now, whenever you want to increment the 'counter1' counter, just do:

{{ increment(counter, 'counter1') }}

Just develop a normal app and then add a couple of lines to the app's manifest file.

First you need to add the following attribute to your activity:

            android:launchMode="singleTask"

Then add two categories to the intent filter :

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.HOME" />

The result could look something like this:

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.dummy.app"
        android:versionCode="1"
        android:versionName="1.0" >

        <uses-sdk
            android:minSdkVersion="11"
            android:targetSdkVersion="19" />

        <application
            android:allowBackup="true"
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/AppTheme" >
            <activity
                android:name="com.dummy.app.MainActivity"
                android:launchMode="singleTask"
                android:label="@string/app_name" >
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
                    <category android:name="android.intent.category.DEFAULT" />
                    <category android:name="android.intent.category.HOME" />
                </intent-filter>
            </activity>
        </application>

    </manifest>

It's that simple!

The easiest way is to import the certificate into a sample firefox-profile and then copy the cert8.db to the users you want equip with the certificate.

First import the certificate by hand into the firefox profile of the sample-user. Then copy

• /home/${USER}/.mozilla/firefox/${randomalphanum}.default/cert8.db (Linux/Unix)

• %userprofile%\Application Data\Mozilla\Firefox\Profiles\%randomalphanum%.default\cert8.db (Windows)

into the users firefox-profiles. That's it. If you want to make sure, that new users get the certificate automatically, copy cert8.db to:

• /etc/firefox-3.0/profile (Linux/Unix)

• %programfiles%\firefox-installation-folder\defaults\profile (Windows)

A simple function. No jquery or other framework is required. Pass your functions as parameters

<div onclick="doubleclick(this, function(){alert('single')}, function(){alert('double')})">click me</div>
    <script>
        function doubleclick(el, onsingle, ondouble) {
            if (el.getAttribute("data-dblclick") == null) {
                el.setAttribute("data-dblclick", 1);
                setTimeout(function () {
                    if (el.getAttribute("data-dblclick") == 1) {
                        onsingle();
                    }
                    el.removeAttribute("data-dblclick");
                }, 300);
            } else {
                el.removeAttribute("data-dblclick");
                ondouble();
            }
        }
    </script>

You should add polls.apps.PollsConfig to INSTALLED_APPS in setting.py

if and grep -Eq

arg='abc'
if echo "$arg" | grep -Eq 'a.c|d.*'; then
  echo 'first'
elif echo "$arg" | grep -Eq 'a{2,3}'; then
  echo 'second'
fi

where:

• -q prevents grep from producing output, it just produces the exit status
• -E enables extended regular expressions

I like this because:

• it is POSIX 7
• it supports extended regular expressions, unlike POSIX case
• the syntax is less clunky than case statements when there are few cases

One downside is that this is likely slower than case since it calls an external grep program, but I tend to consider performance last when using Bash.

case is POSIX 7

Bash appears to follow POSIX by default without shopt as mentioned by https://stackoverflow.com/a/4555979/895245

Here is the quote: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_01 section "Case Conditional Construct":

The conditional construct case shall execute the compound-list corresponding to the first one of several patterns (see Pattern Matching Notation) [...] Multiple patterns with the same compound-list shall be delimited by the '|' symbol. [...]

The format for the case construct is as follows:

case word in
     [(] pattern1 ) compound-list ;;
     [[(] pattern[ | pattern] ... ) compound-list ;;] ...
     [[(] pattern[ | pattern] ... ) compound-list]
  esac

and then http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_13 section "2.13. Pattern Matching Notation" only mentions ?, * and [].

Length of characters to be matched.

{n,m}  n <= length <= m
{n}    length == n
{n,}   length >= n

And by default, the engine is greedy to match this pattern. For example, if the input is 123456789, \d{2,5} will match 12345 which is with length 5.

If you want the engine returns when length of 2 matched, use \d{2,5}?

in Swift 4.2 it is a property now.

override var prefersStatusBarHidden: Bool {
    return true
}

The best I've seen so far is HtmlCleaner:

HtmlCleaner is open-source HTML parser written in Java. HTML found on Web is usually dirty, ill-formed and unsuitable for further processing. For any serious consumption of such documents, it is necessary to first clean up the mess and bring the order to tags, attributes and ordinary text. For the given HTML document, HtmlCleaner reorders individual elements and produces well-formed XML. By default, it follows similar rules that the most of web browsers use in order to create Document Object Model. However, user may provide custom tag and rule set for tag filtering and balancing.

With HtmlCleaner you can locate any element using XPath.

For other html parsers see this SO question.

Try doing this, there's no special character to concatenate in bash :

mystring="${arg1}12${arg2}endoffile"

explanations

If you don't put brackets, you will ask bash to concatenate $arg112 + $argendoffile (I guess that's not what you asked) like in the following example :

mystring="$arg112$arg2endoffile"

The brackets are delimiters for the variables when needed. When not needed, you can use it or not.

another solution

$ arg1=foo
$ arg2=bar
$ mystring="$arg1"
$ mystring+="12"
$ mystring+="$arg2"
$ mystring+="endoffile"
$ echo "$mystring"
foo12barendoffile

See http://mywiki.wooledge.org/BashFAQ/013

This works for me:

var tP = $("img").css("padding").split(" ");
var Padding = {
    Top: tP[0] != null ? parseInt(tP[0]) : 0,
    Right: tP[1] != null ? parseInt(tP[1]) : (tP[0] != null ? parseInt(tP[0]) : 0),
    Bottom: tP[2] != null ? parseInt(tP[2]) : (tP[0] != null ? parseInt(tP[0]) : 0),
    Left: tP[3] != null ? parseInt(tP[3]) : (tP[1] != null ? parseInt(tP[1]) : (tP[0] != null ? parseInt(tP[0]) : 0))
};

Result example:

Object {Top: 5, Right: 8, Bottom: 5, Left: 8}

To make a total:

var TotalPadding = Padding.Top + Padding.Right + Padding.Bottom + Padding.Left;

A percentage value in a height property has a little complication, and the width and height properties actually behave differently to each other. Let me take you on a tour through the specs.

height property:

Let's have a look at what CSS Snapshot 2010 spec says about height:

The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'. A percentage height on the root element is relative to the initial containing block. Note: For absolutely positioned elements whose containing block is based on a block-level element, the percentage is calculated with respect to the height of the padding box of that element.

OK, let's take that apart step by step:

The percentage is calculated with respect to the height of the generated box's containing block.

What's a containing block? It's a bit complicated, but for a normal element in the default static position, it's:

the nearest block container ancestor box

or in English, its parent box. (It's well worth knowing what it would be for fixed and absolute positions as well, but I'm ignoring that to keep this answer short.)

So take these two examples:

<div   id="a"  style="width: 100px; height: 200px; background-color: orange">_x000D_
  <div id="aa" style="width: 100px; height: 50%;   background-color: blue"></div>_x000D_
</div>

<div   id="b"  style="width: 100px;              background-color: orange">_x000D_
  <div id="bb" style="width: 100px; height: 50%; background-color: blue"></div>_x000D_
</div>

In this example, the containing block of #aa is #a, and so on for #b and #bb. So far, so good.

The next sentence of the spec for height is the complication I mentioned in the introduction to this answer:

If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'.

Aha! Whether the height of the containing block has been specified explicitly matters!

• 50% of height:200px is 100px in the case of #aa
• But 50% of height:auto is auto, which is 0px in the case of #bb since there is no content for auto to expand to

As the spec says, it also matters whether the containing block has been absolutely positioned or not, but let's move on to width.

width property:

So does it work the same way for width? Let's take a look at the spec:

The percentage is calculated with respect to the width of the generated box's containing block.

Take a look at these familiar examples, tweaked from the previous to vary width instead of height:

<div   id="c"  style="width: 200px; height: 100px; background-color: orange">_x000D_
  <div id="cc" style="width: 50%;   height: 100px; background-color: blue"></div>_x000D_
</div>

<div   id="d"  style="            height: 100px; background-color: orange">_x000D_
  <div id="dd" style="width: 50%; height: 100px; background-color: blue"></div>_x000D_
</div>

• 50% of width:200px is 100px in the case of #cc
• 50% of width:auto is 50% of whatever width:auto ends up being, unlike height, there is no special rule that treats this case differently.

Now, here's the tricky bit: auto means different things, depending partly on whether its been specified for width or height! For height, it just meant the height needed to fit the contents*, but for width, auto is actually more complicated. You can see from the code snippet that's in this case it ended up being the width of the viewport.

What does the spec say about the auto value for width?

The width depends on the values of other properties. See the sections below.

Wahey, that's not helpful. To save you the trouble, I've found you the relevant section to our use-case, titled "calculating widths and margins", subtitled "block-level, non-replaced elements in normal flow":

The following constraints must hold among the used values of the other properties:

'margin-left' + 'border-left-width' + 'padding-left' + 'width' + 'padding-right' + 'border-right-width' + 'margin-right' = width of containing block

OK, so width plus the relevant margin, border and padding borders must all add up to the width of the containing block (not descendents the way height works). Just one more spec sentence:

If 'width' is set to 'auto', any other 'auto' values become '0' and 'width' follows from the resulting equality.

Aha! So in this case, 50% of width:auto is 50% of the viewport. Hopefully everything finally makes sense now!

You can get div content using .text() in jquery

var divContent = $('#field-function_purpose').text();
console.log(divContent);

All these others answers make sense, but are incomplete. Visual Studio will process XML comments but you have to turn them on. Here's how to do that:

Intellisense will use XML comments you enter in your source code, but you must have them enabled through Visual Studio Options. Go to Tools > Options > Text Editor. For Visual Basic, enable the Advanced > Generate XML documentation comments for ''' setting. For C#, enable the Advanced > Generate XML documentation comments for /// setting. Intellisense will use the summary comments when entered. They will be available from other projects after the referenced project is compiled.

To create external documentation, you need to generate an XML file through the Project Settings > Build > XML documentation file: path that controls the compiler's /doc option. You will need an external tool that will take the XML file as input and generate the documentation in your choice of output formats.

Be aware that generating the XML file can noticeably increase your compile time.

I got fed up with trying to get zeroes, NULLS, and '' accurately round a loop of PHP, MySql and POST values, so I just use 'Yes' and 'No'.

This works flawlessly and needs no special treatment that isn't obvious and easy to do.

Here is my solution based on Skeptic answer. It gets page title from WordPress DB, not from URL because there is a problem with latin characters (slug doesn't has a latin characters). You can also choose to display "home" item or not.

/**
 * Show Breadcrumbs
 * 
 * @param string|bool $home
 * @param string $class
 * @return string
 * 
 * Using: echo breadcrumbs();
 */
function breadcrumbs($home = 'Home', $class = 'items') {
    $breadcrumb  = '<ul class="'. $class .'">';
    $breadcrumbs = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));

    if ($home) {
        $breadcrumb .= '<li><a href="' . get_site_url() . '">' . $home . '</a></li>';
    }

    $path = '';
    foreach ($breadcrumbs as $crumb) {
        $path .=  $crumb . '/';
        $page = get_page_by_path($path);

        if ($home && ($page->ID == get_option('page_on_front'))) {
            continue;
        }

        $breadcrumb .= '<li><a href="'. get_permalink($page) .'">' . $page->post_title . '</a></li>';
    }

    $breadcrumb .= '</ul>';
    return $breadcrumb;
}

Using:

<div class="breadcrumb">
    <div class="container">
        <h3 class="breadcrumb__title">Jazda na maxa!</h3>
        <?php echo breadcrumbs('Start', 'breadcrumb__items'); ?>
    </div>
</div>

If you use the procedural style, you have to provide both a connection and a string:

$name = mysqli_real_escape_string($conn, $name);

Only the object oriented version can be done with just a string:

$name = $link->real_escape_string($name);

The documentation should hopefully make this clear.

form element UI is somewhat controlled by browser and operating system, so it is not trivial to style them very reliably in a way that it would look the same in all common browser/OS combinations.

Instead, if you want something specific, I would recommend to use a library that provides you stylable form elements. uniform.js is one such library.

RenderParital is Better to use for performance.

{@Html.RenderPartial("_LoadView");}

What you are looking for is called Model persistence in sklearn words and it is documented in introduction and in model persistence sections.

So you have initialized your classifier and trained it for a long time with

clf = some.classifier()
clf.fit(X, y)

After this you have two options:

1) Using Pickle

import pickle
# now you can save it to a file
with open('filename.pkl', 'wb') as f:
    pickle.dump(clf, f)

# and later you can load it
with open('filename.pkl', 'rb') as f:
    clf = pickle.load(f)

2) Using Joblib

from sklearn.externals import joblib
# now you can save it to a file
joblib.dump(clf, 'filename.pkl') 
# and later you can load it
clf = joblib.load('filename.pkl')

One more time it is helpful to read the above-mentioned links

Does this work?

Workbooks.Open Filename:=filepath, ReadOnly:=True

Or, as pointed out in a comment, to keep a reference to the opened workbook:

Dim book As Workbook
Set book = Workbooks.Open(Filename:=filepath, ReadOnly:=True)

This issue starting occurring for me when I started working with build.gradle to incorporate the data necessary (signingConfigs) to build a signed .apk. After what appeared to be a successful build from the command line, I discovered that going into any class using R.* that all R.* references were unresolved.

The answers here didn't help me. I decided to re-import the project and it magically fixed the issue. File/Import Project... and select the build.gradle file in my apps root folder. I would love to know why re-import fixed this :)

Guys I have a better solution its short and works perfectly to me. I used it to video. And its perfectly emulates the cover option in css.

Javascript

    $(window).resize(function(){
            //use the aspect ration of your video or image instead 16/9
            if($(window).width()/$(window).height()>16/9){
                $("video").css("width","100%");
                $("video").css("height","auto");
            }
            else{
                $("video").css("width","auto");
                $("video").css("height","100%");
            }
    });

If you flip the if, else you will get contain.

And here is the css. (You don't need to use it if you don't want center positioning, the parent div must be "position:relative")

CSS

video {
position: absolute;
-webkit-transform: translateX(-50%) translateY(-50%);
transform: translateX(-50%) translateY(-50%);
top: 50%;
left: 50%;}

You could use this script:

def run(runfile):
  with open(runfile,"r") as rnf:
    exec(rnf.read())

Syntax:

run("file.py")

Either

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

or

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

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

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

varbinary(max) is the way to go (introduced in SQL Server 2005)

The default value of end is \n meaning that after the print statement it will print a new line. So simply stated end is what you want to be printed after the print statement has been executed

Eg: - print ("hello",end=" +") will print hello +

Both forms of the meta charset declaration are equivalent and should work the same across browsers. But, there are a few things you need to remember when declaring your web files character-set as UTF-8:

1. Save your file(s) in UTF-8 encoding without the byte-order mark (BOM).
2. Declare the encoding in your HTML files using meta charset (like above).
3. Your web server must serve your files, declaring the UTF-8 encoding in the Content-Type HTTP header.

Apache servers are configured to serve files in ISO-8859-1 by default, so you need to add the following line to your .htaccess file:

AddDefaultCharset UTF-8

This will configure Apache to serve your files declaring UTF-8 encoding in the Content-Type response header, but your files must be saved in UTF-8 (without BOM) to begin with.

Notepad cannot save your files in UTF-8 without the BOM. A free editor that can is Notepad++. On the program menu bar, select "Encoding > Encode in UTF-8 without BOM". You can also open files and re-save them in UTF-8 using "Encoding > Convert to UTF-8 without BOM".

More on the Byte Order Mark (BOM) at Wikipedia.

Why don't you just save/serve the CSS file as UTF-8?

nav a:hover:after {
    content: "?";
}

If that's not good enough, and you want to keep it all-ASCII:

nav a:hover:after {
    content: "\2193";
}

The general format for a Unicode character inside a string is \000000 to \FFFFFF – a backslash followed by six hexadecimal digits. You can leave out leading 0 digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.

Relevant part of the CSS2 spec:

Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:

1. with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
2. by providing exactly 6 hexadecimal digits: "\000026B" ("&B")

In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.

If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).

• Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).
  The identifier "te\st" is exactly the same identifier as "test".

Comprehensive list: Unicode Character 'DOWNWARDS ARROW' (U+2193).

Here is an alternate solution to reduce For/ForEach looping, this would reduce looping time and updates quickly :)

 dt.Columns.Add("MyRow", typeof(System.Int32));
 dt.Columns["MyRow"].Expression = "'0'";

Do NOT do that! setNum(num);//fix- until someone fixes your setter. Your getter should not call your setter with the uninitialized value ofnum(e.g.0`).

I suggest making a few small changes -

public static class Vars {   private int num = 5; // Default to 5.    public void setNum(int x) {     this.num = x; // actually "set" the value.   }    public int getNum() {     return num;   } } 

If you want the value from the calling method, then it should wait for the thread to finish, which makes using threads a bit pointless.

To directly answer you question, the value can be stored in any mutable object both the calling method and the thread both have a reference to. You could use the outer this, but that isn't going to be particularly useful other than for trivial examples.

A little note on the code in the question: Extending Thread is usually poor style. Indeed extending classes unnecessarily is a bad idea. I notice you run method is synchronised for some reason. Now as the object in this case is the Thread you may interfere with whatever Thread uses its lock for (in the reference implementation, something to do with join, IIRC).

Neither main() or void main() are standard C. The former is allowed as it has an implicit int return value, making it the same as int main(). The purpose of main's return value is to return an exit status to the operating system.

In standard C, the only valid signatures for main are:

int main(void)

and

int main(int argc, char **argv)

The form you're using: int main() is an old style declaration that indicates main takes an unspecified number of arguments. Don't use it - choose one of those above.

Set selected="selected" for the option you want to be the default.

<option selected="selected">
3
</option>

A somewhat different flavour of the Accepted Answer.

Swift 4

DispatchQueue.main.asyncAfter(deadline: .now() + 0.1 + .milliseconds(500) + 
.microseconds(500) + .nanoseconds(1000)) {
                print("Delayed by 0.1 second + 500 milliseconds + 500 microseconds + 
                      1000 nanoseconds)")
 }

SELECT       `column`,
             COUNT(`column`) AS `value_occurrence` 
    FROM     `my_table`
    GROUP BY `column`
    ORDER BY `value_occurrence` DESC
    LIMIT    1;

Replace column and my_table. Increase 1 if you want to see the N most common values of the column.

As far as I know, if an exception is not caught by your script, it will be interrupted.

You can bind resize using .resize() and run your code when the browser is resized. You need to also add an else condition to your if statement so that your css values toggle the old and the new, rather than just setting the new.

ArrayList<String> al[] = new ArrayList[n+1];
for(int i = 0;i<n;i++){
   al[i] = new ArrayList<String>();
}

let url = NSURL(string: "http://www.test.com")

    let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {(data, response, error) in
        print(NSString(data: data!, encoding: NSUTF8StringEncoding))
    }

    task.resume()

+1 for print_r(). Use it to dump out the contents of an object or variable. To make it more readable, do it with a pre tag so you don't need to view source.

echo '<pre>';
print_r($arrayOrObject);

Also var_dump($thing) - this is very useful to see the type of subthings

char grid[row][col];
memset(grid, ' ', sizeof(grid));

That's for initializing char array elements to space characters.

I needed to read some properties into my code and this works with spring-boot 1.3.0.RELEASE

@Autowired
private ConfigurableListableBeanFactory beanFactory;

// access a properties.yml file like properties
@Bean
public PropertySource properties() {
    PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
    YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
    yaml.setResources(new ClassPathResource("properties.yml"));
    propertySourcesPlaceholderConfigurer.setProperties(yaml.getObject());
    // properties need to be processed by beanfactory to be accessible after
    propertySourcesPlaceholderConfigurer.postProcessBeanFactory(beanFactory);
    return propertySourcesPlaceholderConfigurer.getAppliedPropertySources().get(PropertySourcesPlaceholderConfigurer.LOCAL_PROPERTIES_PROPERTY_SOURCE_NAME);
}

Assuming you want a default button checked.

<div class="row">
    <h1>Radio Group #2</h1>
    <label for="year" class="control-label input-group">Year</label>
    <div class="btn-group" data-toggle="buttons">
        <label class="btn btn-default">
            <input type="radio" name="year" value="2011">2011
        </label>
        <label class="btn btn-default">
            <input type="radio" name="year" value="2012">2012
        </label>
        <label class="btn btn-default active">
            <input type="radio" name="year" value="2013" checked="">2013
        </label>
    </div>
  </div>

Add the active class to the button (label tag) you want defaulted and checked="" to its input tag so it gets submitted in the form by default.

Since python 3.4 you should use pathlib to "touch" files.
It is a much more elegant solution than the proposed ones in this thread.

from pathlib import Path

filename = Path('myfile.txt')
filename.touch(exist_ok=True)  # will create file, if it exists will do nothing
file = open(filename)

Same thing with directories:

filename.mkdir(parents=True, exist_ok=True)
