If the string contains Unicode data (strictly speaking, non-BMP characters) the other methods that have been posted will corrupt it, because you cannot swap the order of high and low surrogate code units when reversing the string. (More information about this can be found on my blog.)

The following code sample will correctly reverse a string that contains non-BMP characters, e.g., "\U00010380\U00010381" (Ugaritic Letter Alpa, Ugaritic Letter Beta).

public static string Reverse(this string input)
{
    if (input == null)
        throw new ArgumentNullException("input");

    // allocate a buffer to hold the output
    char[] output = new char[input.Length];
    for (int outputIndex = 0, inputIndex = input.Length - 1; outputIndex < input.Length; outputIndex++, inputIndex--)
    {
        // check for surrogate pair
        if (input[inputIndex] >= 0xDC00 && input[inputIndex] <= 0xDFFF &&
            inputIndex > 0 && input[inputIndex - 1] >= 0xD800 && input[inputIndex - 1] <= 0xDBFF)
        {
            // preserve the order of the surrogate pair code units
            output[outputIndex + 1] = input[inputIndex];
            output[outputIndex] = input[inputIndex - 1];
            outputIndex++;
            inputIndex--;
        }
        else
        {
            output[outputIndex] = input[inputIndex];
        }
    }

    return new string(output);
}

Try this it works for me,

<style>_x000D_
    select{_x000D_
        border: 0 !important;  /*Removes border*/_x000D_
        -webkit-appearance: none;_x000D_
        -moz-appearance: none;_x000D_
        appearance: none;_x000D_
        text-overflow:'';_x000D_
        text-indent: 0.01px; /* Removes default arrow from firefox*/_x000D_
        text-overflow: "";  /*Removes default arrow from firefox*/_x000D_
    }_x000D_
    select::-ms-expand {_x000D_
        display: none;_x000D_
    }_x000D_
    .select-wrapper_x000D_
    {_x000D_
        padding-left:0px;_x000D_
        overflow:hidden;_x000D_
    }_x000D_
</style>_x000D_
    _x000D_
<div class="select-wrapper">_x000D_
     <select> ... </select>_x000D_
</div>

You can not hide but using overflow hidden you can actually make it disappear.

According to the ewerybody post: https://stackoverflow.com/a/29275361/7530957

Multiple problems can arise:

• Multiple processes with the same name
• Name of the long process

The 'ewerybody's' code will not work if the process name is long. So there is a problem with this line:

last_line.lower().startswith(process_name.lower())

Because last_line will be shorter than the process name.

So if you just want to know if a process/processes is/are active:

from subprocess import check_output

def process_exists(process_name):
    call = 'TASKLIST', '/FI', 'imagename eq %s' % process_name
    if check_output(call).splitlines()[3:]:
        return True

Instead for all the information of a process/processes

from subprocess import check_output

def process_exists(process_name):
    call = 'TASKLIST', '/FI', 'imagename eq %s' % process_name
    processes = []
    for process in check_output(call).splitlines()[3:]:
        process = process.decode()
        processes.append(process.split())
    return processes

Try using the ToDictionary method like so:

var dict = TableObj.ToDictionary( t => t.Key, t => t.TimeStamp );

You can do that by storing cookies on client side.

Ctrl + H is the best way! Remember to copy the string before you start searching!

Original answer Nov 20 '15:

No option for a specific tag as of Today. Docker compose just does its magic and assigns a tag like you are seeing. You can always have some script call docker tag <image> <tag> after you call docker-compose.

Now there's an option as described above or here

build: ./dir
image: webapp:tag

There are multiple options available for generating HTML reports for Selenium WebDriver scripts.

1. Use the JUNIT TestWatcher class for creating your own Selenium HTML reports

The TestWatcher JUNIT class allows overriding the failed() and succeeded() JUNIT methods that are called automatically when JUNIT tests fail or pass.

The TestWatcher JUNIT class allows overriding the following methods:

• protected void failed(Throwable e, Description description)

failed() method is invoked when a test fails

• protected void finished(Description description)

finished() method is invoked when a test method finishes (whether passing or failing)

• protected void skipped(AssumptionViolatedException e, Description description)

skipped() method is invoked when a test is skipped due to a failed assumption.

• protected void starting(Description description)

starting() method is invoked when a test is about to start

• protected void succeeded(Description description)

succeeded() method is invoked when a test succeeds

See below sample code for this case:

import static org.junit.Assert.assertTrue;
import org.junit.Test;

public class TestClass2 extends WatchManClassConsole {

    @Test public void testScript1() {
        assertTrue(1 < 2); >
    }

    @Test public void testScript2() {
        assertTrue(1 > 2);
    }

    @Test public void testScript3() {
        assertTrue(1 < 2);
    }

    @Test public void testScript4() {
        assertTrue(1 > 2);
    }
}

import org.junit.Rule; 
import org.junit.rules.TestRule; 
import org.junit.rules.TestWatcher; 
import org.junit.runner.Description; 
import org.junit.runners.model.Statement; 

public class WatchManClassConsole {

    @Rule public TestRule watchman = new TestWatcher() { 

        @Override public Statement apply(Statement base, Description description) { 
            return super.apply(base, description); 
        } 

        @Override protected void succeeded(Description description) { 
            System.out.println(description.getDisplayName() + " " + "success!"); 
        } 

        @Override protected void failed(Throwable e, Description description) { 
            System.out.println(description.getDisplayName() + " " + e.getClass().getSimpleName()); 
        }
    }; 
}

2. Use the Allure Reporting framework

Allure framework can help with generating HTML reports for your Selenium WebDriver projects.

The reporting framework is very flexible and it works with many programming languages and unit testing frameworks.

You can read everything about it at http://allure.qatools.ru/.

You will need the following dependencies and plugins to be added to your pom.xml file

1. maven surefire
2. aspectjweaver
3. allure adapter

See more details including code samples on this article: http://test-able.blogspot.com/2015/10/create-selenium-html-reports-with-allure-framework.html

From Google Code FAQ - Creating a Store Locator with PHP, MySQL & Google Maps:

Here's the SQL statement that will find the closest 20 locations that are within a radius of 25 miles to the 37, -122 coordinate. It calculates the distance based on the latitude/longitude of that row and the target latitude/longitude, and then asks for only rows where the distance value is less than 25, orders the whole query by distance, and limits it to 20 results. To search by kilometers instead of miles, replace 3959 with 6371.

SELECT id, ( 3959 * acos( cos( radians(37) ) * cos( radians( lat ) ) 
* cos( radians( lng ) - radians(-122) ) + sin( radians(37) ) * sin(radians(lat)) ) ) AS distance 
FROM markers 
HAVING distance < 25 
ORDER BY distance 
LIMIT 0 , 20;

You can get the selected item from Spinner by using,

interested.getSelectedItem().toString();

Thay are removed.

Use float-left instead of pull-left. And float-right instead of pull-right.

Check bootstrap Documentation here:

Added .float-{sm,md,lg,xl}-{left,right,none} classes for responsive floats and removed .pull-left and .pull-right since they’re redundant to .float-left and .float-right.

I'm surprised no one really got into blocking/non-blocking call issues

For blocking/non-blocking call issues regarding NSTask read below:

Source code of asynctask.m is available at GitHub.

You're confusing the dereference operator * with pointer type annotation *. Basically, in C * means different things in different places:

• In a type, * means a pointer. int is an integer type, int* is a pointer to integer type
• As a prefix operator, * means 'dereference'. name is a pointer, *name is the result of dereferencing it (i.e. getting the value that the pointer points to)
• Of course, as an infix operator, * means 'multiply'.

The URI RFC (of which URLs are a subset) doesn't define a maximum length, however, it does recommend that the hostname part of the URI (if applicable) not exceed 255 characters in length:

URI producers should use names that conform to the DNS syntax, even when use of DNS is not immediately apparent, and should limit these names to no more than 255 characters in length.

As noted in other posts though, some browsers have a practical limitation on the length of a URL.

I needed to simulate a browser login to a website to get a login cookie, and the login form was multipart/form-data.

I took some clues from the other answers here, and then tried to get my own scenario working. It took a bit of frustrating trial and error before it worked right, but here is the code:

    public static class WebHelpers
    {
        /// <summary>
        /// Post the data as a multipart form
        /// </summary>
       public static HttpWebResponse MultipartFormDataPost(string postUrl, string userAgent, Dictionary<string, string> values)
       {
           string formDataBoundary = "---------------------------" + WebHelpers.RandomHexDigits(12);
           string contentType = "multipart/form-data; boundary=" + formDataBoundary;

           string formData = WebHelpers.MakeMultipartForm(values, formDataBoundary);
           return WebHelpers.PostForm(postUrl, userAgent, contentType, formData);
       }

        /// <summary>
        /// Post a form
        /// </summary>
        public static HttpWebResponse PostForm(string postUrl, string userAgent, string contentType, string formData)
        {
            HttpWebRequest request = WebRequest.Create(postUrl) as HttpWebRequest;

            if (request == null)
            {
                throw new NullReferenceException("request is not a http request");
            }

            // Add these, as we're doing a POST
            request.Method = "POST";
            request.ContentType = contentType;
            request.UserAgent = userAgent;
            request.CookieContainer = new CookieContainer();

            // We need to count how many bytes we're sending. 
            byte[] postBytes = Encoding.UTF8.GetBytes(formData);
            request.ContentLength = postBytes.Length;

            using (Stream requestStream = request.GetRequestStream())
            {
                // Push it out there
                requestStream.Write(postBytes, 0, postBytes.Length);
                requestStream.Close();
            }

            return request.GetResponse() as HttpWebResponse;
        }

        /// <summary>
        /// Generate random hex digits 
        /// </summary>
        public static string RandomHexDigits(int count)
        {
            Random random = new Random();
            StringBuilder result = new StringBuilder();
            for (int i = 0; i < count; i++)
            {
                int digit = random.Next(16);
                result.AppendFormat("{0:x}", digit);
            }

            return result.ToString();
        }

        /// <summary>
        /// Turn the key and value pairs into a multipart form
        /// </summary>
        private static string MakeMultipartForm(Dictionary<string, string> values, string boundary)
        {
            StringBuilder sb = new StringBuilder();

            foreach (var pair in values)
            {
                sb.AppendFormat("--{0}\r\nContent-Disposition: form-data; name=\"{1}\"\r\n\r\n{2}\r\n", boundary, pair.Key, pair.Value);
            }

            sb.AppendFormat("--{0}--\r\n", boundary);

            return sb.ToString();    
        }
    }
}

It doesn't handle file data, just form since that's all that I needed. I called like this:

    try
    {
        using (HttpWebResponse response = WebHelpers.MultipartFormDataPost(postUrl, UserAgentString, this.loginForm)) 
        {
            if (response != null)
            {
                Cookie loginCookie = response.Cookies["logincookie"];
                .....

This matches everything up to ".txt" (without including it):

^.*(?=(\.txt))

// Enable scrolling based on content height self.tableView.scrollEnabled = table.contentSize.height > table.frame.size.height;

It sets result to the (unsigned) value resulting from putting the 8 bits of value in the lowest 8 bits of result.

The reason something like this is necessary is that byte is a signed type in Java. If you just wrote:

int result = value;

then result would end up with the value ff ff ff fe instead of 00 00 00 fe. A further subtlety is that the & is defined to operate only on int values¹, so what happens is:

1. value is promoted to an int (ff ff ff fe).
2. 0xff is an int literal (00 00 00 ff).
3. The & is applied to yield the desired value for result.

(The point is that conversion to int happens before the & operator is applied.)

1_{Well, not quite. The & operator works on long values as well, if either operand is a long. But not on byte. See the Java Language Specification, sections 15.22.1 and 5.6.2.}

Based on First answer here is the complete image selection options:

Filter = @"|All Image Files|*.BMP;*.bmp;*.JPG;*.JPEG*.jpg;*.jpeg;*.PNG;*.png;*.GIF;*.gif;*.tif;*.tiff;*.ico;*.ICO
           |PNG|*.PNG;*.png
           |JPEG|*.JPG;*.JPEG*.jpg;*.jpeg
           |Bitmap(.BMP,.bmp)|*.BMP;*.bmp                                    
           |GIF|*.GIF;*.gif
           |TIF|*.tif;*.tiff
           |ICO|*.ico;*.ICO";

ScriptManager.RegisterStartupScript(this, this.GetType(), Guid.NewGuid().ToString(),script,  true );

The "true" param value at the end of the ScriptManager.RegisterStartupScript will add a JavaScript tag inside your page:

<script language='javascript' defer='defer'>your script</script >

If the value will be "false" it will inject only the script witout the --script-- tag.

Alternative way to do this using sklearn

from sklearn.utils import shuffle
X=[1,2,3]
y = ['one', 'two', 'three']
X, y = shuffle(X, y, random_state=0)
print(X)
print(y)

Output:

[2, 1, 3]
['two', 'one', 'three']

Advantage: You can random multiple arrays simultaneously without disrupting the mapping. And 'random_state' can control the shuffling for reproducible behavior.

This is an answered question, but I'll give my "one cent":

Business rules belong in the model. The "model" always consists of (logically or physically separated):

• presentation model - a set of classes that is well suited for use in the view (it's tailored toward specific UI/presentation),
• domain model - the UI-independent portion of the model, and
• repository - the storage-aware portion of the "model".

Business rules live in the domain model, are exposed in a presentation-suitable form to the "presentation" model and are sometimes duplicated (or also enforced) in the "data layer".

Try this for check null

 if (text == nil)

String.replaceAll("[\n\r]", "");

If you are creating the TableModel automatically from a set of values (with "new JTable(Vector, Vector)"), perhaps it is easier to remove editors from columns:

JTable table = new JTable(my_rows, my_header);

for (int c = 0; c < table.getColumnCount(); c++)
{
    Class<?> col_class = table.getColumnClass(c);
    table.setDefaultEditor(col_class, null);        // remove editor
}

Without editors, data will be not editable.

You can use :nth-last-child(); in fact, besides :nth-last-of-type() I don't know what else you could use. I'm not sure what you mean by "dynamic", but if you mean whether the style applies to the new second last child when more children are added to the list, yes it will. Interactive fiddle.

ul li:nth-last-child(2)

You don't need to do anything special, actually. You can mix JavaScript and PHP together to get variables from PHP straight into JavaScript.

var param1val = '<?php echo $_GET['param1'] ?>';

If you want to echo it out for later execution it's ok

If you want to execute the JS and use the results in PHP use V8JS

V8Js::registerExtension('say_hi', 'print("hey from extension! "); var said_hi=true;', array(), true);
$v8 = new V8Js();
$v8->executeString('print("hello from regular code!")', 'test.php');
$v8->executeString('if (said_hi) { print(" extension already said hi"); }');

You can refer here for further reference: What are Extensions in php v8js?

If you want to execute HTML&JS and use the output in PHP http://htmlunit.sourceforge.net/ is your solution

If your project is Maven-based, remember to set scope to provided for such dependencies as servlet-api, jsp-api. Otherwise, these jars will be exported to WEB-INF/lib and hence contaminate with those in Tomcat server. That causes painful problems.

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>servlet-api</artifactId>
  <version>2.5</version>
  <scope>provided</scope>
</dependency>
<dependency>
  <groupId>javax.servlet.jsp</groupId>
  <artifactId>jsp-api</artifactId>
  <version>2.1</version>
  <scope>provided</scope>
</dependency>

If you are using Spring as Back-End server and especially using Spring Security then i found a solution by putting http.cors(); in the configure method. The method looks like that:

protected void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .authorizeRequests() // authorize
                .anyRequest().authenticated() // all requests are authenticated
                .and()
                .httpBasic();

        http.cors();
}

cq.select(cb.construct(entityClazz.class, root.get("ID"), root.get("VERSION")));  // HERE IS NO ERROR

https://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Basic_JPA_Development/Querying/Criteria#Constructors

Note that there are multiple iPad Pros, each with a different Viewports: When emulating an iPad Pro via the Chrome developer tools, the iPad Pro (12.9") is the default option. If you want to emulate one of the other iPad Pros (10.5" or 9.7") with a different viewport, you'll need to add a custom emulated device with the correct specs.

You can search devices, viewports, and their respective CSS media queries at: http://vizdevices.yesviz.com/devices.php.

For instance, the iPad Pro (12.9") would have the following media queries:

/* Landscape */ 
@media only screen and (min-width: 1366px) and (orientation: landscape) { /* Your Styles... */ }

/*Portrait*/ 
@media only screen and (min-width: 1024px) and (orientation: portrait) { /* Your Styles... */ }

Whereas the iPad Pro (10.5") will have:

/* Landscape */ 
@media only screen and (min-device-width: 1112px) and (orientation: landscape) { /* Your Styles... */ }

/*Portrait*/ 
@media only screen and (min-device-width: 834px) and (orientation: portrait) { /* Your Styles... */ }

Here's an example that shows how table(.) (or, more closely matching your desired output, data.frame(table(.)) does what it sounds like you are asking for.

Note also how to share reproducible sample data in a way that others can copy and paste into their session.

Here's the (reproducible) sample data:

mydf <- structure(list(ID = c(110L, 111L, 121L, 131L, 141L), 
                       MONTH.YEAR = c("JAN. 2012", "JAN. 2012", 
                                      "FEB. 2012", "FEB. 2012", 
                                      "MAR. 2012"), 
                       VALUE = c(1000L, 2000L, 3000L, 4000L, 5000L)), 
                  .Names = c("ID", "MONTH.YEAR", "VALUE"), 
                  class = "data.frame", row.names = c(NA, -5L))

mydf
#    ID MONTH.YEAR VALUE
# 1 110  JAN. 2012  1000
# 2 111  JAN. 2012  2000
# 3 121  FEB. 2012  3000
# 4 131  FEB. 2012  4000
# 5 141  MAR. 2012  5000

Here's the calculation of the number of rows per group, in two output display formats:

table(mydf$MONTH.YEAR)
# 
# FEB. 2012 JAN. 2012 MAR. 2012 
#         2         2         1

data.frame(table(mydf$MONTH.YEAR))
#        Var1 Freq
# 1 FEB. 2012    2
# 2 JAN. 2012    2
# 3 MAR. 2012    1

You should have a 'skeleton' somewhere in /etc, probably /etc/skeleton, or check the default settings, probably /etc/default or something. Those are scripts that define standard environment variables getting set during a login.

If it is just for your own account: check the (hidden) file ~/.profile and ~/.login. Or generate them, if they don't exist. These are also evaluated by the login process.

If you are using a declarative syntax of Jenkinsfile to describe your building pipeline, you can use changeset condition to limit stage execution only to the case when specific files are changed. This is now a standard feature of Jenkins and does not require any additional configruation/software.

stages {
    stage('Nginx') {
        when { changeset "nginx/*"}
        steps {
            sh "make build-nginx"
            sh "make start-nginx"
        }
    }
}

You can combine multiple conditions using anyOf or allOf keywords for OR or AND behaviour accordingly:

when {
    anyOf {
        changeset "nginx/**"
        changeset "fluent-bit/**"
    }
}
steps {
    sh "make build-nginx"
    sh "make start-nginx"
}

Some notes that I also found useful:

• Keep your default values on the right side.

  function whatever($var1, $var2, $var3="constant", $var4="another")
  

• The default value of the argument must be a constant expression. It can't be a variable or a function call.

I would recommend using the coding standards from IDesign or the ones listed on Brad Abram's website. Those are the best two that I have found.

Brad would say...

Classes member should be alphabetized, and grouped into sections (Fields, Constructors, Properties, Events, Methods, Private interface implementations, Nested types)

Probably the shortest solution (works only in modern browsers)

This small piece of CSS makes "the middle content part fill 100% of the space in between with the footer fixed to the bottom":

html, body { height: 100%; }
your_container { min-height: calc(100% - height_of_your_footer); }

the only requirement is that you need to have a fixed height footer.

For example for this layout:

    <html><head></head><body>
      <main> your main content </main>
      </footer> your footer content </footer>
    </body></html>

you need this CSS:

    html, body { height: 100%; }
    main { min-height: calc(100% - 2em); }
    footer { height: 2em; }

For an example of the css styles have a look at: http://getbootstrap.com/examples/theme/

If you want to see how the example looks without the bootstrap-theme.css file open up your browser developer tools and delete the link from the <head> of the example and then you can compare it.

I know this is an old question but posted it just in case anyone is looking for an example of how it looks like I was.

Update

bootstrap.css = main css framework (grids, basic styles, etc)

bootstrap-theme.css = extended styling (3D buttons, gradients etc). This file is optional and does not effect the functionality of bootstrap at all, it only enhances the appearance.

Update 2

With the release of v3.2.0 Bootstrap have added an option to view the theme css on the doc pages. If you go to one of the doc pages (css, components, javascript) you should see a "Preview theme" link at the bottom of the side nav which you can use to turn the theme css on and off.

Why not use the get function?

var a = [1,2,3,4];
var last = $(a).get(-1);

Edit: As pointed out by DelightedD0D, this isn't the correct function to use as per jQuery's docs but it does still provide the correct results. I recommend using Salty's answer to keep your code correct.

font/woff2

For nginx add the following to the mime.types file:

font/woff2 woff2;

Old Answer

The mime type (sometime written as mimetype) for WOFF2 fonts has been proposed as application/font-woff2.

Also, if you refer to the spec (http://dev.w3.org/webfonts/WOFF2/spec/) you will see that font/woff2 is being discussed. I suspect that the filal mime type for all fonts will eventually be the more logical font/* (font/ttf, font/woff2 etc)...

N.B. WOFF2 is still in 'Working Draft' status -- not yet adopted officially.

I like this for a simple check from the shell:

mysql -p<password> -D<database> -B -e "SHOW TABLES LIKE 'User%'" \
| awk 'NR != 1 {print "CHECK TABLE "$1";"}' \
| mysql -p<password> -D<database>

Very old question, but I tried everything suggested above and still could not get it resolved.

Turns out that, I had after insert/update trigger for the main table which tracked the changes by inserting the record in history table having similar structure. I increased the size in the main table column but forgot to change the size of history table column and that created the problem.

I did similar changes in the other table and error is gone.

I had this issue for 2 days, let me show you how I fixed it.

This was how the code looked when I was getting the error:

request.onload = function() {
    // This is where we begin accessing the Json
    let data = JSON.parse(this.response);
    console.log(data)
}

This is what I changed to get the result I wanted:

request.onload = function() {
    // This is where we begin accessing the Json
    let data = JSON.parse(this.responseText);
    console.log(data)
}

So all I really did was change this.response to this.responseText.

Try this: import headers as mentioned.. gives seconds and milliseconds only. If you need to explain the code read this link.

#include <windows.h>

#include <stdio.h>

void main()
{

    SYSTEMTIME st;
    SYSTEMTIME lt;

    GetSystemTime(&st);
   // GetLocalTime(&lt);

     printf("The system time is: %02d:%03d\n", st.wSecond, st.wMilliseconds);
   //  printf("The local time is: %02d:%03d\n", lt.wSecond, lt.wMilliseconds);

}

I was successful using tidy command line utility. On linux I installed it quickly with apt-get install tidy. Then the command:

tidy -q -asxml --numeric-entities yes source.html >file.xml

gave an xml file, which I was able to process with xslt processor. However I needed to set up xhtml1 dtds correctly.

This is their homepage: html-tidy.org (and the legacy one: HTML Tidy)

Another option is to use the case-insensitive flag i, then there's no need for the extra character range A-Z.

var reg = /^[a-z]+$/i;
console.log( reg.test("somethingELSE") ); //true
console.log( "somethingELSE".match(reg)[0] ); //"somethingELSE"

Here's a DEMO on how this regex works with test() and match().

In plain JavaScript,

if (document.layers) {
  document.captureEvents(Event.KEYDOWN);
}

document.onkeydown = function (evt) {
  var keyCode = evt ? (evt.which ? evt.which : evt.keyCode) : event.keyCode;
  if (keyCode == 13) {
    // For Enter.
    // Your function here.
  }
  if (keyCode == 27) {
    // For Escape.
    // Your function here.
  } else {
    return true;
  }
};

I noticed that the reply is given in jQuery only, so I thought of giving something in plain JavaScript as well.

We can use replace to change the values in 'mpg' to NA that corresponds to cyl==4.

mtcars %>%
     mutate(mpg=replace(mpg, cyl==4, NA)) %>%
     as.data.frame()

Create a function and copy the code using winsock which is mentioned already by Software_Developer.

For Instance:

#ifdef _WIN32

// this is required only for windows

if (WSAStartup(MAKEWORD(2,2), &wsaData) != 0)
{

  //...

}

#endif

winsock code here

#ifdef _WIN32

WSACleanup();

#endif

You need to alias the subquery. Thus, your statement should be:

Select Z.id
From    (
        Select id, time
        From dbo.tablea
        Union All
        Select id, time
        From dbo.tableb
        ) As Z
Group By Z.id

public class X { static {
  System.out.println("Main not required to print this");
  System.exit(0);
}}

Run from the cmdline with java X.

I like List comprehensions because of their Math (Set) syntax. So how about this:

L = [1, 2, 3, 4, 5, 6, 7]
odd_numbers = [y for x,y in enumerate(L) if x%2 != 0]
even_numbers = [y for x,y in enumerate(L) if x%2 == 0]

Basically, if you enumerate over a list, you'll get the index x and the value y. What I'm doing here is putting the value y into the output list (even or odd) and using the index x to find out if that point is odd (x%2 != 0).

If you use a TFS online(Cloud version) and you want to transform the App.Config in a project, you can do the following without installing any extra tools. From VS => Unload the project => Edit project file => Go to the bottom of the file and add the following:

<UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
<Target Name="AfterBuild" Condition="Exists('App.$(Configuration).config')">
<TransformXml Source="App.config" Transform="App.$(Configuration).config" Destination="$(OutDir)\$(AssemblyName).dll.config" />

AssemblyFile and Destination works for local use and TFS online(Cloud) server.

I face this problem but resolution is very simple. I am writing the 1 MB file in 1024 Byte Buffer causing this issue. To Understand refer code before and After Fix.

Code with Excepion

DataOutputStream dos = new DataOutputStream(s.getOutputStream());
        FileInputStream fis = new FileInputStream(file);
        byte[] buffer = new byte[1024];
        
        while (fis.read(buffer) > 0) {
            dos.write(buffer);
        }
    

After Fixes:

DataOutputStream dos = new DataOutputStream(s.getOutputStream());
        FileInputStream fis = new FileInputStream(file);
        byte[] buffer = new byte[102400];
        
        while (fis.read(buffer) > 0) {
            dos.write(buffer);
        }

Along the lines of Tim Down's answer but leveraging jQuery (mentioned by the OP) and loosely coupling the containing page and the iframe, you could do the following:

In the iframe:

<script>
    $(function() {
        var w = window;
        if (w.frameElement != null
                && w.frameElement.nodeName === "IFRAME"
                && w.parent.jQuery) {
            w.parent.jQuery(w.parent.document).trigger('iframeready');
        }
    });
</script>

In the containing page:

<script>
    function myHandler() {
        alert('iframe (almost) loaded');
    }
    $(document).on('iframeready', myHandler);
</script>

The iframe fires an event on the (potentially existing) parent window's document - please beware that the parent document needs a jQuery instance of itself for this to work. Then, in the parent window you attach a handler to react to that event.

This solution has the advantage of not breaking when the containing page does not contain the expected load handler. More generally speaking, it shouldn't be the concern of the iframe to know its surrounding environment.

Please note, that we're leveraging the DOM ready event to fire the event - which should be suitable for most use cases. If it's not, simply attach the event trigger line to the window's load event like so:

$(window).on('load', function() { ... });

You can modify the whole InfoWindow using jquery alone...

var popup = new google.maps.InfoWindow({
    content:'<p id="hook">Hello World!</p>'
});

Here the <p> element will act as a hook into the actual InfoWindow. Once the domready fires, the element will become active and accessible using javascript/jquery, like $('#hook').parent().parent().parent().parent().

The below code just sets a 2 pixel border around the InfoWindow.

google.maps.event.addListener(popup, 'domready', function() {
    var l = $('#hook').parent().parent().parent().siblings();
    for (var i = 0; i < l.length; i++) {
        if($(l[i]).css('z-index') == 'auto') {
            $(l[i]).css('border-radius', '16px 16px 16px 16px');
            $(l[i]).css('border', '2px solid red');
        }
    }
});

You can do anything like setting a new CSS class or just adding a new element.

Play around with the elements to get what you need...

Try like this:

$data = array('current_login' => date('Y-m-d H:i:s'));
$this->db->set('last_login', 'current_login', false);
$this->db->where('id', 'some_id');
$this->db->update('login_table', $data);

Pay particular attention to the set() call's 3rd parameter. false prevents CodeIgniter from quoting the 2nd parameter -- this allows the value to be treated as a table column and not a string value. For any data that doesn't need to special treatment, you can lump all of those declarations into the $data array.

The query generated by above code:

UPDATE `login_table`
SET last_login = current_login, `current_login` = '2018-01-18 15:24:13'
WHERE `id` = 'some_id'

It appears I cannot use an if statement.

Arrow functions either allow to use an expression or a block as their body. Passing an expression

foo => bar

is equivalent to the following block

foo => { return bar; }

However,

if (person.age > 18) person

is not an expression, if is a statement. Hence you would have to use a block, if you wanted to use if in an arrow function:

foo => {  if (person.age > 18) return person; }

While that technically solves the problem, this a confusing use of .filter, because it suggests that you have to return the value that should be contained in the output array. However, the callback passed to .filter should return a Boolean, i.e. true or false, indicating whether the element should be included in the new array or not.

So all you need is

family.filter(person => person.age > 18);

In ES5:

family.filter(function (person) {
  return person.age > 18;
});

While creating setup for www.spotdekho.com in new windows10 machine, I was unable to run command "nodemon web.js" due same error

"Error: Cannot find module '../build/Release/bson'"

Got it fixed by below steps :

1. Create folder "Release" inside "node_modules\bson\build\" location
2. Copy bson.js from "node_modules\bson\browser_build\"
3. Paste bson.js inside "node_modules\bson\build\Release" folder.

This will resolve the issue.

PS : I am using mongoose version 4.8.8 .

Thanks :) , hope it helps someone .

defaultMember already is an alias - it doesn't need to be the name of the exported function/thing. Just do

import alias from 'my-module';

Alternatively you can do

import {default as alias} from 'my-module';

but that's rather esoteric.

If you do not want to use constructors, and you want to have a special name for the method, try it this:

public enum MyType {
  ONE {
      public String getDescription() {
          return "this is one";
      }
  },    
  TWO {
      public String getDescription() {
          return "this is two";
      }
  };

  public abstract String getDescription();
}

I suspect that this is the quickest solution. There is no need to use variables final.

this will also work:

fs.readFile(`${__dirname}/../../foo.bar`);

What you are trying to do is get NTLM to forward the identity on to the next server, which it cannot do - it can only do impersonation which only gives you access to local resources. It won't let you cross a machine boundary. Kerberos authentication supports delegation (what you need) by using tickets, and the ticket can be forwarded on when all servers and applications in the chain are correctly configured and Kerberos is set up correctly on the domain. So, in short you need to switch from using NTLM to Kerberos.

For more on Windows Authentication options available to you and how they work start at: http://msdn.microsoft.com/en-us/library/ff647076.aspx

Have a look at localize, or l

eg:

l Time.at(1100897479)

open the location in terminal then type these commands 1. chmod +x filename.sh 2. ./filename.sh that's it

If the performance hit of the default constructor isn't an issue, the please, for the love of god, go with the more readable version.

Overview

• Context: Perl 5.x
• Problem: The user wishes to merge two hashes¹ into a single variable

Solution

• use the syntax above for simple variables
• use Hash::Merge for complex nested variables

Pitfalls

• What do to when both hashes contain one or more duplicate keys
  • (see e.g., Perl - Merge hash containing duplicate keys)
  • (see e.g, Perl hashes: how to deal with duplicate keys and get possible pair)
• Should a key-value pair with an empty value ever overwrite a key-value pair with a non-empty value?
  • What constitutes an empty vs non-empty value in the first place? (eg. undef, zero, empty string, false, falsy ...)

No you can't they are different. When the app was deployed your controller mappings would be borked for example.

Why do you want to anyway, a controller is not a service, and vice versa.

I don't know why but animating only the visibility property is not working on any browser.

What you can do is animate the opacity property in such a way that the browser doesn't have enough frames to fade in or out the text.

Example:

span {_x000D_
  opacity: 0;_x000D_
  animation: blinking 1s linear infinite;_x000D_
}_x000D_
_x000D_
@keyframes blinking {_x000D_
  from,_x000D_
  49.9% {_x000D_
    opacity: 0;_x000D_
  }_x000D_
  50%,_x000D_
  to {_x000D_
    opacity: 1;_x000D_
  }_x000D_
}

<span>I'm blinking text</span>

You need to designate the logfile name when calling the sql loader.

The safest command to push different local Git branches to Heroku/master.

git push -f heroku branch_name:master

Note: Although, you can push without using the -f, the -f (force flag) is recommended in order to avoid conflicts with other developers’ pushes.

When pinging two systems, by default SSH is enabled (if you have connected via putty or terminal.) To allow ping, I added the security group for each of the instance (inbound).

String a = new String("foo");
String b = new String("foo");
System.out.println(a == b); // prints false
System.out.println(a.equals(b)); // prints true

Make sure you understand why. It's because the == comparison only compares references; the equals() method does a character-by-character comparison of the contents.

When you call new for a and b, each one gets a new reference that points to the "foo" in the string table. The references are different, but the content is the same.

There might be different issues with running PostgreSQL locally. I would recommend to clean all versions of postgres installed and start fresh. Once you have it installed, it's very easy to recreate your database if you have your rails project with the up to date db/schema.rb

Here is how I usually install PostgreSQL on a Mac. If you're running your database under the root user locally, you might want to omit the last step that creates a todo user

Throwable is super class of Exception as well as Error. In normal cases we should always catch sub-classes of Exception, so that the root cause doesn't get lost.

Only special cases where you see possibility of things going wrong which is not in control of your Java code, you should catch Error or Throwable.

I remember catching Throwable to flag that a native library is not loaded.

None of the answers helped me, so I'm posting the solution that worked for me, all I had to do is to import the SQLPS module, I realized this when by accident I ran the Restore-SqlDatabase command and started working, meaning that the assembly was referenced in that module somehow.

Just run:

Import-module SQLPS

Note: Thanks Jason for noting that SQLPS is deprecated

instead run:

Import-Module SqlServer

or

Install-Module SqlServer

Look for this:

ANY page in your project that has a missing, or different Namespace...

If you have ANY page in your project with <NO Namespace> , OR a

DIFFERENT Namespace than Default.aspx, you will get this

"Cannot load Default.aspx", or this: "Default.aspx does not belong here".

ALSO: If you have a Redirect to a page in your Solution/Project and the page which is to be Redirected To has a bad namespace -- you may not get a compiler error, until you try and run. If the Redirect is removed or commented-out, the error goes away...

BTW -- What the hell do these error messages mean? Is this MS.Access, with the "misdirection" -- ??

Here is a base R answer using aggregate and ave :

df1 <- with(mtcars, aggregate(list(n = mpg), list(am = am, gear = gear), length))
df1$prop <- with(df1, n/ave(n, am, FUN = sum))
#Also with prop.table
#df1$prop <- with(df1, ave(n, am, FUN = prop.table))
df1

#  am gear  n      prop
#1  0    3 15 0.7894737
#2  0    4  4 0.2105263
#3  1    4  8 0.6153846
#4  1    5  5 0.3846154 

We can also use prop.table but the output displays differently.

prop.table(table(mtcars$am, mtcars$gear), 1)
   
#            3         4         5
#  0 0.7894737 0.2105263 0.0000000
#  1 0.0000000 0.6153846 0.3846154

I think, UNSIGNED would be the best option to store something like time_duration(Eg: resolved_call_time = resolved_time(DateTime)-creation_time(DateTime)) value in minutes or hours or seconds format which will definitely be a non-negative number

Just tell the file-input to automatically submit the form on any change:

<form action="http://example.com">_x000D_
    <input type="file" onchange="form.submit()" />_x000D_
</form>

This solution works like this:

• onchange makes the input element execute the following script, whenever the value is modified
• form references the form, that this input element is part of
• submit() causes the form to send all data to the URL, as specified in action

Advantages of this solution:

• Works without ids. It makes life easier, if you have several forms in one html page.
• Native javascript, no jQuery or similar required.
• The code is inside the html-tags. If you inspect the html, you will see it's behavior right away.

Total memory in Mb:

EDIT Ignore this answer. There are now better answers. See the comments. Use + theme_classic()

EDIT

This is a better version. The bug mentioned below in the original post remains (I think). But the axis line is drawn under the panel. Therefore, remove both the panel.border and panel.background to see the axis lines.

library(ggplot2)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

ggplot(df, aes(x = a, y = b)) + geom_point() +
  theme_bw() +
  theme(axis.line = element_line(colour = "black"),
    panel.grid.major = element_blank(),
    panel.grid.minor = element_blank(),
    panel.border = element_blank(),
    panel.background = element_blank()) 

Original post This gets close. There was a bug with axis.line not working on the y-axis (see here), that appears not to be fixed yet. Therefore, after removing the panel border, the y-axis has to be drawn in separately using geom_vline.

library(ggplot2)
library(grid)

a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

p = ggplot(df, aes(x = a, y = b)) + geom_point() +
   scale_y_continuous(expand = c(0,0)) +
   scale_x_continuous(expand = c(0,0)) +
   theme_bw() +
   opts(axis.line = theme_segment(colour = "black"),
        panel.grid.major = theme_blank(),
        panel.grid.minor = theme_blank(),
        panel.border = theme_blank()) +
    geom_vline(xintercept = 0)
p

The extreme points are clipped, but the clipping can be undone using code by baptiste.

gt <- ggplot_gtable(ggplot_build(p))
gt$layout$clip[gt$layout$name=="panel"] <- "off"
grid.draw(gt)

Or use limits to move the boundaries of the panel.

ggplot(df, aes(x = a, y = b)) + geom_point() +
   xlim(0,22) +  ylim(.95, 2.1) +
   scale_x_continuous(expand = c(0,0), limits = c(0,22)) +
   scale_y_continuous(expand = c(0,0), limits = c(.95, 2.2)) +   
   theme_bw() +
   opts(axis.line = theme_segment(colour = "black"),
        panel.grid.major = theme_blank(),
        panel.grid.minor = theme_blank(),
        panel.border = theme_blank()) +
    geom_vline(xintercept = 0)

For me what worked in ubuntu image:

RUN echo "en_US.UTF-8 UTF-8" >> /etc/locale.gen
RUN echo "LANG=en_US.UTF-8" > /etc/locale.conf

make sure that your path is pointing to .exe file in C:\Program Files\7-Zip (may in bin directory)

One possible way is to use .map() method:

var all = $(".mbox").map(function() {
    return this.innerHTML;
}).get();

console.log(all.join());

DEMO: http://jsfiddle.net/Y4bHh/

N.B. Please don't use document.write. For testing purposes console.log is the best way to go.

You could also write your entire function as a jQuery extension, so you could do something along the lines of `$('#element').showHideOther();

(function($) {
    $.extend($.fn, {
        showHideOther: function() {
            $.each(this, function() {
                var Id = $(this).attr('id');
                alert(Id);

                ...

                return this;
            });
        }
    });
})(jQuery);

Not that it answers your question... Just food for thought.

Just use the following code with initializing a field

private int count = 0;
    @Override
public void onBackPressed() {
    count++;
    if (count >=1) {

I got the same error and ended up using a pre-built distribution of numpy available in SourceForge (similarly, a distribution of matplotlib can be obtained).

Builds for both 32-bit 2.7 and 3.3/3.4 are available.
PyCharm detected them straight away, of course.

Run dos2unix or similar utility on it to remove the carriage returns (^M).

This message indicates that your file has dos-style lineendings:

-bash: /backup/backup.sh: /bin/bash^M: bad interpreter: No such file or directory 

Utilities like dos2unix will fix it:

 dos2unix <backup.bash >improved-backup.sh 

Or, if no such utility is installed, you can accomplish the same thing with translate:

tr -d "\015\032" <backup.bash >improved-backup.sh 

As for how those characters got there in the first place, @MadPhysicist had some good comments.

Maybe you can write a function in ~/.zshrc, ~/.bashrc .

# set my env
[ -s ~/.env ] && export MYENV=`cat ~/.env`
function myenv() { [[ -s ~/.env ]] && echo $argv > ~/.env && export MYENV=$argv }

Beacause of use variable outside, you can avoid write script file.

if you want to append to a file

with open("test.txt", "a") as myfile:
    myfile.write("append me")

We declared the variable myfile to open a file named test.txt. Open takes 2 arguments, the file that we want to open and a string that represents the kinds of permission or operation we want to do on the file

here is file mode options

Mode    Description

'r' This is the default mode. It Opens file for reading.
'w' This Mode Opens file for writing. 
If file does not exist, it creates a new file.
If file exists it truncates the file.
'x' Creates a new file. If file already exists, the operation fails.
'a' Open file in append mode. 
If file does not exist, it creates a new file.
't' This is the default mode. It opens in text mode.
'b' This opens in binary mode.
'+' This will open a file for reading and writing (updating)

If you have Mathematica, you can try with this command:

ReadList["filename.txt", Record, RecordSeparators -> {}] // InputForm

That will show all the /r and /n

In framework 3.5, dt.Rows.Cast<System.Data.DataRow>().Take(n)

Otherwise the way you mentioned

In order to match a digit, you can use [0-9].

So you could use 5[0-9][0-9][0-9][0-9][0-9][0-9] and [0-9][0-9][0-9][0-9]7[0-9][0-9][0-9]. I do this a lot for zip codes.

I have used the below code in my existing project

<div class="form-group" [ngStyle]="{'border':isSubmitted && form_data.controls.first_name.errors?'1px solid red':'' }">
</div>

This may be obvious, but you can inline the array like so:

package main

import (
    "fmt"
)

func main() {
    for _, element := range [3]string{"a", "b", "c"} {
        fmt.Print(element)
    }
}

outputs:

abc

I researched on the internet and some answers includes enabling the "access for lesser app" and "unlocking gmail captcha" which sadly didn't work for me until I found the 2-step verification.

What I did the following was:

1. enable the 2-step verification to google HERE

2. Create App Password to be use by your system HERE

3. I selected Others (custom name) and clicked generate

4. Went to my env file in laravel and edited this

   [email protected]

   MAIL_PASSWORD=thepasswordgenerated

5. Restarted my apache server and boom! It works again.

This was my solution. I created this to atleast make other people not go wasting their time researching for a possible answer.

i'll make an example, first decide what browser you want to emulate, in this case i chose Firefox 60.6.1esr (64-bit), and check what GET request it issues, this can be obtained with a simple netcat server (MacOS bundles netcat, most linux distributions bunles netcat, and Windows users can get netcat from.. Cygwin.org , among other places),

setting up the netcat server to listen on port 9999: nc -l 9999

now hitting http://127.0.0.1:9999 in firefox, i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

now let us compare that with this simple script:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_exec($ch);

i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
Accept: */*

there are several missing headers here, they can all be added with the CURLOPT_HTTPHEADER option of curl_setopt, but the User-Agent specifically should be set with CURLOPT_USERAGENT instead (it will be persistent across multiple calls to curl_exec() and if you use CURLOPT_FOLLOWLOCATION then it will persist across http redirections as well), and the Accept-Encoding header should be set with CURLOPT_ENCODING instead (if they're set with CURLOPT_ENCODING then curl will automatically decompress the response if the server choose to compress it, but if you set it via CURLOPT_HTTPHEADER then you must manually detect and decompress the content yourself, which is a pain in the ass and completely unnecessary, generally speaking) so adding those we get:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

now running that code, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept-Encoding: gzip, deflate
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Connection: keep-alive
Upgrade-Insecure-Requests: 1

and voila! our php-emulated browser GET request should now be indistinguishable from the real firefox GET request :)

this next part is just nitpicking, but if you look very closely, you'll see that the headers are stacked in the wrong order, firefox put the Accept-Encoding header in line 6, and our emulated GET request puts it in line 3.. to fix this, we can manually put the Accept-Encoding header in the right line,

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Accept-Encoding: gzip, deflate',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

running that, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

problem solved, now the headers is even in the correct order, and the request seems to be COMPLETELY INDISTINGUISHABLE from the real firefox request :) (i don't actually recommend this last step, it's a maintenance burden to keep CURLOPT_ENCODING in sync with the custom Accept-Encoding header, and i've never experienced a situation where the order of the headers are significant)

Why don't you multiply that number with -1?

Like This:

//Given x as the number, if x is less than 0, return 0 - x, otherwise return x:
return (x <= 0.0F) ? 0.0F - x : x;

The path you give to LOAD DATA INFILE is for the filesystem on the machine where the server is running, not the machine you connect from. LOAD DATA LOCAL INFILE is for the client's machine, but it requires that the server was started with the right settings, otherwise it's not allowed. You can read all about it here: http://dev.mysql.com/doc/refman/5.0/en/load-data-local.html

As for SELECT INTO OUTFILE I'm not sure why there is not a local version, besides it probably being tricky to do over the connection. You can get the same functionality through the mysqldump tool, but not through sending SQL to the server.

For US Address Parsing,

I ran into this same issue trying to deploy my MVC3 Razor web application on GoDaddy shared hosting. There are some additional .dlls that need to be referenced. Details here: http://paulmason.biz/?p=108

Basically you need to add references to the following in addition to the ones listed in @Haacked's post and set them to deploy locally as described.

• Microsoft.Web.Infrastructure
• System.Web.Razor
• System.Web.WebPages.Deployment
• System.Web.WebPages.Razor

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

You should be aware of various tracking tools like Google Analytics also use cookies on your domain and you don't want to delete them, if you want to have correct data in GA.

The only solution I could get working was to set the existing cookies to null. I couldn't delete the cookies from the client.

So for logging a user out I use the following:

setcookie("username", null, time()+$this->seconds, "/", $this->domain, 0);
setcookie("password", null, time()+$this->seconds, "/", $this->domain, 0);

Of course this doesn't delete ALL cookies.

The semantics of setTimeout are roughly the same as in a web browser: the timeout arg is a minimum number of ms to wait before executing, not a guarantee. Furthermore, passing 0, a non-number, or a negative number, will cause it to wait a minimum number of ms. In Node, this is 1ms, but in browsers it can be as much as 50ms.

The reason for this is that there is no preemption of JavaScript by JavaScript. Consider this example:

setTimeout(function () {
  console.log('boo')
}, 100)
var end = Date.now() + 5000
while (Date.now() < end) ;
console.log('imma let you finish but blocking the event loop is the best bug of all TIME')

The flow here is:

1. schedule the timeout for 100ms.
2. busywait for 5000ms.
3. return to the event loop. check for pending timers and execute.

If this was not the case, then you could have one bit of JavaScript "interrupt" another. We'd have to set up mutexes and semaphors and such, to prevent code like this from being extremely hard to reason about:

var a = 100;
setTimeout(function () {
  a = 0;
}, 0);
var b = a; // 100 or 0?

The single-threadedness of Node's JavaScript execution makes it much simpler to work with than most other styles of concurrency. Of course, the trade-off is that it's possible for a badly-behaved part of the program to block the whole thing with an infinite loop.

Is this a better demon to battle than the complexity of preemption? That depends.

First, HTML and PDF are not related although they were created around the same time. HTML is intended to convey higher level information such as paragraphs and tables. Although there are methods to control it, it is ultimately up to the browser to draw these higher level concepts. PDF is intended to convey documents and the documents must "look" the same wherever they are rendered.

In an HTML document you might have a paragraph that's 100% wide and depending on the width of your monitor it might take 2 lines or 10 lines and when you print it it might be 7 lines and when you look at it on your phone it might take 20 lines. A PDF file, however, must be independent of the rendering device, so regardless of your screen size it must always render exactly the same.

Because of the musts above, PDF doesn't support abstract things like "tables" or "paragraphs". There are three basic things that PDF supports: text, lines/shapes and images. (There are other things like annotations and movies but I'm trying to keep it simple here.) In a PDF you don't say "here's a paragraph, browser do your thing!". Instead you say, "draw this text at this exact X,Y location using this exact font and don't worry, I've previously calculated the width of the text so I know it will all fit on this line". You also don't say "here's a table" but instead you say "draw this text at this exact location and then draw a rectangle at this other exact location that I've previously calculated so I know it will appear to be around the text".

Second, iText and iTextSharp parse HTML and CSS. That's it. ASP.Net, MVC, Razor, Struts, Spring, etc, are all HTML frameworks but iText/iTextSharp is 100% unaware of them. Same with DataGridViews, Repeaters, Templates, Views, etc. which are all framework-specific abstractions. It is your responsibility to get the HTML from your choice of framework, iText won't help you. If you get an exception saying The document has no pages or you think that "iText isn't parsing my HTML" it is almost definite that you don't actually have HTML, you only think you do.

Third, the built-in class that's been around for years is the HTMLWorker however this has been replaced with XMLWorker (Java / .Net). Zero work is being done on HTMLWorker which doesn't support CSS files and has only limited support for the most basic CSS properties and actually breaks on certain tags. If you do not see the HTML attribute or CSS property and value in this file then it probably isn't supported by HTMLWorker. XMLWorker can be more complicated sometimes but those complications also make it more extensible.

Below is C# code that shows how to parse HTML tags into iText abstractions that get automatically added to the document that you are working on. C# and Java are very similar so it should be relatively easy to convert this. Example #1 uses the built-in HTMLWorker to parse the HTML string. Since only inline styles are supported the class="headline" gets ignored but everything else should actually work. Example #2 is the same as the first except it uses XMLWorker instead. Example #3 also parses the simple CSS example.

2017's update

There are good news for HTML-to-PDF demands. As this answer showed, the W3C standard css-break-3 will solve the problem... It is a Candidate Recommendation with plan to turn into definitive Recommendation this year, after tests.

As not-so-standard there are solutions, with plugins for C#, as showed by print-css.rocks.

Here is a simple web crawler, i used BeautifulSoup and we will search for all the links(anchors) who's class name is _3NFO0d. I used Flipkar.com, it is an online retailing store.

import requests
from bs4 import BeautifulSoup
def crawl_flipkart():
    url = 'https://www.flipkart.com/'
    source_code = requests.get(url)
    plain_text = source_code.text
    soup = BeautifulSoup(plain_text, "lxml")
    for link in soup.findAll('a', {'class': '_3NFO0d'}):
        href = link.get('href')
        print(href)

crawl_flipkart()

Distinct the Note class by Author

var DistinctItems = Note.GroupBy(x => x.Author).Select(y => y.First());

foreach(var item in DistinctItems)
{
    //Add to other List
}

According to Extensible Messaging and Presence Protocol (Wikipedia), the standard TCP port for the server is 5222.

The client would presumably use the same ports as the messaging protocol, but can also use http (port 80) and https (port 443) for message delivery. These have the advantage of working for users behind firewalls, so your network admin should not need to get involved.

Here's a short version:

$('#ddlCodes').change(function() {
  $('#txtEntry2').text($(this).find(":selected").text());
});

karim79 made a good catch, judging by your element name txtEntry2 may be a textbox, if it's any kind of input, you'll need to use .val() instead or .text() like this:

  $('#txtEntry2').val($(this).find(":selected").text());

For the "what's wrong?" part of the question: .text() doesn't take a selector, it takes text you want it set to, or nothing to return the text already there. So you need to fetch the text you want, then put it in the .text(string) method on the object you want to set, like I have above.

The async is currently supported by all latest versions of the major browsers. It has been supported for some years now on most browsers.

You can keep track of which browsers support async (and defer) in the MDN website here:

I found it easier to move the files into a separate Class Library project and then reference that project in the web project and apply the namespace in the using section of the file. For some reason the other solutions were not working for me, but this work around did.

I had the same problem, and I found the solution in this post of Sam Goddard,

The solution if to defined the call to the font twice. First as it is recommended, to be used for all the browsers, and after a particular call only for Chrome with a special media query:

@font-face {
  font-family: 'chunk-webfont';
  src: url('../../includes/fonts/chunk-webfont.eot');
  src: url('../../includes/fonts/chunk-webfont.eot?#iefix') format('eot'),
  url('../../includes/fonts/chunk-webfont.woff') format('woff'),
  url('../../includes/fonts/chunk-webfont.ttf') format('truetype'),
  url('../../includes/fonts/chunk-webfont.svg') format('svg');
  font-weight: normal;
  font-style: normal;
}

@media screen and (-webkit-min-device-pixel-ratio:0) {
  @font-face {
    font-family: 'chunk-webfont';
    src: url('../../includes/fonts/chunk-webfont.svg') format('svg');
  }
}

With this method the font will render good in all browsers. The only negative point that I found is that the font file is also downloaded twice.

For a simple Spring application, you don't have to define ContextLoaderListener in your web.xml; you can just put all your Spring configuration files in <servlet>:

<servlet>
    <servlet-name>hello</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/mvc-core-config.xml, classpath:spring/business-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

For a more complex Spring application, where you have multiple DispatcherServlet defined, you can have the common Spring configuration files that are shared by all the DispatcherServlet defined in the ContextLoaderListener:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring/common-config.xml</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
    <servlet-name>mvc1</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/mvc1-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet>
    <servlet-name>mvc2</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/mvc2-config.xmll</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

Just keep in mind, ContextLoaderListener performs the actual initialization work for the root application context.

I found this article helps a lot: Spring MVC – Application Context vs Web Application Context

class Student(object):
    name = ""
    age = 0
    major = ""

    # The class "constructor" - It's actually an initializer 
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

def make_student(name, age, major):
    student = Student(name, age, major)
    return student

Note that even though one of the principles in Python's philosophy is "there should be one—and preferably only one—obvious way to do it", there are still multiple ways to do this. You can also use the two following snippets of code to take advantage of Python's dynamic capabilities:

class Student(object):
    name = ""
    age = 0
    major = ""

def make_student(name, age, major):
    student = Student()
    student.name = name
    student.age = age
    student.major = major
    # Note: I didn't need to create a variable in the class definition before doing this.
    student.gpa = float(4.0)
    return student

I prefer the former, but there are instances where the latter can be useful – one being when working with document databases like MongoDB.

You are trying to assign an array to ngClass, but the syntax for the array elements is wrong since you separate them with a || instead of a ,.

Try this:

<section [ngClass]="[menu1 ? 'class1' : '',  menu2 ? 'class1' : '', (something && (menu1 || menu2)) ? 'class2' : '']">

This other option should also work:

<section [ngClass.class1]="menu1 || menu2" [ngClass.class2] = "(menu1 || menu2) && something">    

According to this article on sqlserverstudymaterial;

Remember that "%Privileged time" is not based on 100%.It is based on number of processors.If you see 200 for sqlserver.exe and the system has 8 CPU then CPU consumed by sqlserver.exe is 200 out of 800 (only 25%).

If "% Privileged Time" value is more than 30% then it's generally caused by faulty drivers or anti-virus software. In such situations make sure the BIOS and filter drives are up to date and then try disabling the anti-virus software temporarily to see the change.

If "% User Time" is high then there is something consuming of SQL Server. There are several known patterns which can be caused high CPU for processes running in SQL Server including

The solution for this is that remove this following dependency:

implementation 'com.android.support:design:26.1.0'

put general dependencies as:

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:support-compat:26.1.0'
    implementation 'com.android.support:multidex:1.0.3'    
    implementation 'com.android.support:support-v4:26.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.facebook.android:audience-network-sdk:4.99.1'
}

if you already know your folder is: E:\ftproot\sales then you do not need to use Server.MapPath, this last one is needed if you only have a relative virtual path like ~/folder/folder1 and you want to know the real path in the disk...

It's really easy to create folders. Actually it's just creating keys.

You can see my below code i was creating a folder with utc_time as name.

Do remember ends the key with '/' like below, this indicates it's a key:

Key='folder1/' + utc_time + '/'

client = boto3.client('s3')
utc_timestamp = time.time()


def lambda_handler(event, context):

    UTC_FORMAT = '%Y%m%d'
    utc_time = datetime.datetime.utcfromtimestamp(utc_timestamp)
    utc_time = utc_time.strftime(UTC_FORMAT)
    print 'start to create folder for => ' + utc_time

    putResponse = client.put_object(Bucket='mybucketName',
                                    Key='folder1/' + utc_time + '/')

    print putResponse

The best "Pythonic" way to do this, exploiting the with statement, is listed as Example #6 in PEP 343, which gives the background of the statement.

@contextmanager
def opened_w_error(filename, mode="r"):
    try:
        f = open(filename, mode)
    except IOError, err:
        yield None, err
    else:
        try:
            yield f, None
        finally:
            f.close()

Used as follows:

with opened_w_error("/etc/passwd", "a") as (f, err):
    if err:
        print "IOError:", err
    else:
        f.write("guido::0:0::/:/bin/sh\n")

You can use the TelephonyManager to do this:

TelephonyManager t = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); 
String number = t.getLine1Number();

Have you used

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

By using Moment.js, i able to set the default time

var defaultStartTime = moment(new Date());
var _startTimeStr = "02:00 PM"


    if (moment(_startTimeStr, 'HH:mm a').isValid()) {
        var hr = moment(_startTimeStr, 'HH:mm a').hour();
        var min = moment(_startTimeStr, 'HH:mm a').minutes();

        defaultStartTime = defaultStartTime.hours(hr).minutes(min);
    }

$('#StartTime').datetimepicker({
    pickDate: false,
    defaultDate: defaultStartTime
});

(Explanation in more details can be found in an archived Microsoft KB article.)

Three things to know:

1. The percent sign is used in batch files to represent command line parameters: %1, %2, ...

2. Two percent signs with any characters in between them are interpreted as a variable:

   echo %myvar%

3. Two percent signs without anything in between (in a batch file) are treated like a single percent sign in a command (not a batch file): %%f

Why's that?

For example, if we execute your (simplified) command line

FOR /f %f in ('dir /b .') DO somecommand %f

in a batch file, rule 2 would try to interpret

%f in ('dir /b .') DO somecommand %

as a variable. In order to prevent that, you have to apply rule 3 and escape the % with an second %:

FOR /f %%f in ('dir /b .') DO somecommand %%f

It is a reference to the current file name. In the file foo.rb, __FILE__ would be interpreted as "foo.rb".

Edit: Ruby 1.9.2 and 1.9.3 appear to behave a little differently from what Luke Bayes said in his comment. With these files:

# test.rb
puts __FILE__
require './dir2/test.rb'

# dir2/test.rb
puts __FILE__

Running ruby test.rb will output

test.rb
/full/path/to/dir2/test.rb

My experience in Visual Studio 2010 is that there are two changes needed so as to not need DLL's. From the project property page (right click on the project name in the Solution Explorer window):

1. Under Configuration Properties --> General, change the "Use of MFC" field to "Use MFC in a Static Library".

2. Under Configuration Properties --> C/C++ --> Code Generation, change the "Runtime Library" field to "Multi-Threaded (/MT)"

Not sure why both were needed. I used this to remove a dependency on glut32.dll.

Added later: When making these changes to the configurations, you should make them to "All Configurations" --- you can select this at the top of the Properties window. If you make the change to just the Debug configuration, it won't apply to the Release configuration, and vice-versa.

intern ? symbol Returns the Symbol corresponding to str, creating the symbol if it did not previously exist

"edition".intern # :edition

http://ruby-doc.org/core-2.1.0/String.html#method-i-intern

The code

my_list = [(1, 2), (3, 4), (5, 6)]
for t in my_list:
    print t

prints

(1, 2)
(3, 4)
(5, 6)

The loop iterates over my_list, and assigns the elements of my_list to t one after the other. The elements of my_list happen to be tuples, so t will always be a tuple. To access the first element of the tuple t, use t[0]:

for t in my_list:
    print t[0]

To access the first element of the tuple at the given index i in the list, you can use

print my_list[i][0]

\d+

\d represents any digit, + for one or more. If you want to catch negative numbers as well you can use -?\d+.

Note that as a string, it should be represented in C# as "\\d+", or @"\d+"

    var l = document.getElementsByClassName("chatMessages").length;
    document.getElementsByClassName("chatMessages")[l-1].scrollIntoView();

this should work

Search for MySql.Data package, when you find it click on Install

Here is the sample controller which connects to MySql database using the mysql package. We mainly make use of MySqlConnection connection object.

 public class HomeController : Controller
{
    public ActionResult Index()
    {
        List<employeemodel> employees = new List<employeemodel>();
        string constr = ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;
        using (MySqlConnection con = new MySqlConnection(constr))
        {
            string query = "SELECT EmployeeId, Name, Country FROM Employees";
            using (MySqlCommand cmd = new MySqlCommand(query))
            {
                cmd.Connection = con;
               con.Open();
                using (MySqlDataReader sdr = cmd.ExecuteReader())
                {
                    while (sdr.Read())
                    {
                        employees.Add(new EmployeeModel
                        {
                            EmployeeId = Convert.ToInt32(sdr["EmployeeId"]),
                            Name = sdr["Name"].ToString(),
                            Country = sdr["Country"].ToString()
                        });
                    }
                }
                con.Close();
            }
        }

        return View(employees);
    }
}

The goal you indicate in the command line is linked to the lifecycle of Maven. For example, the build lifecycle (you also have the clean and site lifecycles which are different) is composed of the following phases:

• validate: validate the project is correct and all necessary information is available.
• compile: compile the source code of the project.
• test: test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed.
• package: take the compiled code and package it in its distributable format, such as a JAR.
• integration-test: process and deploy the package if necessary into an environment where integration tests can be run.
• verify: run any checks to verify the package is valid and meets quality criteria
• install: install the package into the local repository, for use as a dependency in other projects locally.
• deploy: done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.

You can find the list of "core" plugins here, but there are plenty of others plugins, such as the codehaus ones, here.

There is no right way, but you can initialize an array of literals:

char **values = (char *[]){"a", "b", "c"};

or you can allocate each and initialize it:

char **values = malloc(sizeof(char*) * s);
for(...)
{
    values[i] = malloc(sizeof(char) * l);
    //or
    values[i] = "hello";
}

This answer may have to be modified depending on what you were trying to achieve with position: fixed;. If all you want is two columns side by side then do the following:

http://jsfiddle.net/8weSA/1/

I floated both columns to the left.

Note: I added min-height to each column for illustrative purposes and I simplified your CSS.

body {_x000D_
  background-color: #444;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
#wrapper {_x000D_
  width: 1005px;_x000D_
  margin: 0 auto;_x000D_
}_x000D_
_x000D_
#leftcolumn,_x000D_
#rightcolumn {_x000D_
  border: 1px solid white;_x000D_
  float: left;_x000D_
  min-height: 450px;_x000D_
  color: white;_x000D_
}_x000D_
_x000D_
#leftcolumn {_x000D_
  width: 250px;_x000D_
  background-color: #111;_x000D_
}_x000D_
_x000D_
#rightcolumn {_x000D_
  width: 750px;_x000D_
  background-color: #777;_x000D_
}

<div id="wrapper">_x000D_
  <div id="leftcolumn">_x000D_
    Left_x000D_
  </div>_x000D_
  <div id="rightcolumn">_x000D_
    Right_x000D_
  </div>_x000D_
</div>

If you would like the left column to stay in place as you scroll do the following:

http://jsfiddle.net/8weSA/2/

Here we float the right column to the right while adding position: relative; to #wrapper and position: fixed; to #leftcolumn.

Note: I again used min-height for illustrative purposes and can be removed for your needs.

body {_x000D_
  background-color: #444;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
#wrapper {_x000D_
  width: 1005px;_x000D_
  margin: 0 auto;_x000D_
  position: relative;_x000D_

#leftcolumn,_x000D_
#rightcolumn {_x000D_
  border: 1px solid white;_x000D_

You can use a temporary deletion list:

List<String> keyList = new ArrayList<String>;

for(Map.Entry<String,String> entry : hashTable){
  if(entry.getValue().equals("delete")) // replace with your own check
    keyList.add(entry.getKey());
}

for(String key : keyList){
  hashTable.remove(key);
}

You can find more information about Hashtable methods in the Java API

I had a similar problem trying to POST to MailGun for some automated emails I was implementing in an app.

I was able to get this working properly with a large HTTP response. I put the full path into Keys.plist so that I can upload my code to github and broke out some of the arguments into variables so I can have them programmatically set later down the road.

// Email the FBO with desired information
// Parse our Keys.plist so we can use our path
var keys: NSDictionary?

if let path = NSBundle.mainBundle().pathForResource("Keys", ofType: "plist") {
    keys = NSDictionary(contentsOfFile: path)
}

if let dict = keys {
    // variablize our https path with API key, recipient and message text
    let mailgunAPIPath = dict["mailgunAPIPath"] as? String
    let emailRecipient = "[email protected]"
    let emailMessage = "Testing%20email%20sender%20variables"

    // Create a session and fill it with our request
    let session = NSURLSession.sharedSession()
    let request = NSMutableURLRequest(URL: NSURL(string: mailgunAPIPath! + "from=FBOGo%20Reservation%20%3Cscheduler@<my domain>.com%3E&to=reservations@<my domain>.com&to=\(emailRecipient)&subject=A%20New%20Reservation%21&text=\(emailMessage)")!)

    // POST and report back with any errors and response codes
    request.HTTPMethod = "POST"
    let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
        if let error = error {
            print(error)
        }

        if let response = response {
            print("url = \(response.URL!)")
            print("response = \(response)")
            let httpResponse = response as! NSHTTPURLResponse
            print("response code = \(httpResponse.statusCode)")
        }
    })
    task.resume()
}

The Mailgun Path is in Keys.plist as a string called mailgunAPIPath with the value:

https://API:key-<my key>@api.mailgun.net/v3/<my domain>.com/messages?

Hope this helps offers a solution to someone trying to avoid using 3rd party code for their POST requests!

I'm currently using SDK 20.0.3 and none of the previous solutions worked for me.

The reason that hessdroid works where hess failed is because the two jar files contain java that is compiled for different virtual machines. The byte code created by the Java compiler is not guaranteed to run on the Dalvik virtual machine. The byte code created by the Android compiler is not guaranteed to run on the Java virtual machine.

In my case I had access to the source code and was able to create an Android jar file for it using the method that I described here: https://stackoverflow.com/a/13144382/545064

In addition, it is also possible to turn logging off programmatically:

Logger.getRootLogger().setLevel(Level.OFF);

Or

Logger.getRootLogger().removeAllAppenders();
Logger.getRootLogger().addAppender(new NullAppender());

These use imports:

import org.apache.log4j.Logger;
import org.apache.log4j.Level;
import org.apache.log4j.NullAppender;

Easy way to find angle between two vectors(works for n-dimensional vector),

Python code:

import numpy as np

vector1 = [1,0,0]
vector2 = [0,1,0]

unit_vector1 = vector1 / np.linalg.norm(vector1)
unit_vector2 = vector2 / np.linalg.norm(vector2)

dot_product = np.dot(unit_vector1, unit_vector2)

angle = np.arccos(dot_product) #angle in radian

Remove the width and display: block and then add display: inline-block to the button. To have it remain centered you can either add text-align: center; on the body or do the same on a newly created container.

The advantage of this approach (as opossed to centering with auto margins) is that the button will remain centered regardless of how much text it has.

Example: http://cssdeck.com/labs/2u4kf6dv

Here is my example of how to change the arrows for Slick Carousel in React to anything you would like. First you need to set the nextArrow and prevArrow in settings to a function then return a div in that function with whatever icon you would like to use. For mine I used Font Awesome. Then you will need to add a className in your icon, you will see that in the NextArrow and PrevArrow functions. Then add the scss code to customize whatever you would like.

JSX Code:

function NextArrow(props) {
  const { style, onClick } = props;
  return (
    <div style={{ ...style, display: "block" }} onClick={onClick}>
      <FontAwesomeIcon icon={faChevronRight} size="3x" className="slick-arrow-icon-right" />
    </div>
  );
}

function PrevArrow(props) {
  const { style, onClick } = props;
  return (
    <div style={{ ...style, display: "block" }} onClick={onClick}>
      <FontAwesomeIcon icon={faChevronLeft} size="3x" className="slick-arrow-icon-left" />
    </div>
  );
}

function SlickCarouselArrowChange(props) {
  var settings = {
    className: "slider variable-width",
    dots: true,
    infinite: true,
    centerMode: true,
    slidesToShow: 1,
    slidesToScroll: 1,
    variableWidth: true,
    autoplay: true,
    autoplaySpeed: 2000,
    nextArrow: <NextArrow />,
    prevArrow: <PrevArrow />,
  };

  return (
    <div className="slick-slider">
      <Slider {...settings}>
        {props.searchResults.map((image, index) => (
          <div key={index}>
            <img src={image.urls.small} />{" "}
          </div>
        ))}
      </Slider>
    </div>
  );
}

SCSS Code:

.slick-arrow-icon-left,
.slick-arrow-icon-right {
  position: absolute;
  display: block;
  cursor: pointer;
  background: transparent;
  color: black;
  top: 50%;
  -webkit-transform: translate(0, -50%);
  -ms-transform: translate(0, -50%);
  transform: translate(0, -50%);
  padding: 0;
  border: none;
  outline: none;
  transition: 0.5s ease-in-out;
  &:hover,
  &:focus {
    outline: none;
    background: transparent;
    color: black;
    font-size: 40px;
    &::before {
      opacity: 1;
    }
  }
}

.slick-arrow-icon-left {
  left: -50px;
  [dir="rtl"] & {
    left: auto;
    right: -50px;
  }
}

.slick-arrow-icon-right {
  right: -50px;
  [dir="rtl"] & {
    left: -50px;
    right: auto;
  }
}

You can use strcpy but remember to end the array with '\0'

char array[20]; char string[100];

array[0]='1'; array[1]='7'; array[2]='8'; array[3]='.'; array[4]='9'; array[5]='\0';
strcpy(string, array);
printf("%s\n", string);

Simply :first works for me, why isn't this mentioned yet?

new_vector.assign(old_vector.begin(),old_vector.end()); // Method 1
new_vector = old_vector; // Method 2

I am assuming (please correct me if I am wrong) that you want to re-display the edit page if the edit fails and to do this you are using a redirect.

You may have more luck by just returning the view again rather than trying to redirect the user, this way you will be able to use the ModelState to output any errors too.

Edit:

Updated based on feedback. You can place the previous URL in the viewModel, add it to a hidden field then use it again in the action that saves the edits.

For instance:

public ActionResult Index()
{
    return View();
}

[HttpGet] // This isn't required
public ActionResult Edit(int id)
{
   // load object and return in view
   ViewModel viewModel = Load(id);

   // get the previous url and store it with view model
   viewModel.PreviousUrl = System.Web.HttpContext.Current.Request.UrlReferrer;

   return View(viewModel);
}

[HttpPost]
public ActionResult Edit(ViewModel viewModel)
{
   // Attempt to save the posted object if it works, return index if not return the Edit view again

   bool success = Save(viewModel);
   if (success)
   {
       return Redirect(viewModel.PreviousUrl);
   }
   else
   {
      ModelState.AddModelError("There was an error");
      return View(viewModel);
   }
}

The BeginForm method for your view doesn't need to use this return URL either, you should be able to get away with:

@model ViewModel

@using (Html.BeginForm())
{
    ...
    <input type="hidden" name="PreviousUrl" value="@Model.PreviousUrl" />
}

Going back to your form action posting to an incorrect URL, this is because you are passing a URL as the 'id' parameter, so the routing automatically formats your URL with the return path.

This won't work because your form will be posting to an controller action that won't know how to save the edits. You need to post to your save action first, then handle the redirect within it.

If you dont want a plugin there is a very simple solution

$("textarea").keyup(function(e) {
    while($(this).outerHeight() < this.scrollHeight + parseFloat($(this).css("borderTopWidth")) + parseFloat($(this).css("borderBottomWidth"))) {
        $(this).height($(this).height()+1);
    };
});

See it working in a jsFiddle I used to answer another textarea question here.

To answer the question of doing it in reverse or making it smaller as text is removed: jsFiddle

And if you do want a plugin

@Jason has designed one here

"how can i return a array in a c++ method and how must i declare it? int[] test(void); ??"

template <class X>
  class Array
{
  X     *m_data;
  int    m_size;
public:
    // there constructor, destructor, some methods
    int Get(X* &_null_pointer)
    {
        if(!_null_pointer)
        {
            _null_pointer = new X [m_size];
            memcpy(_null_pointer, m_data, m_size * sizeof(X));
            return m_size;
        }
       return 0;
    }
}; 

just for int

class IntArray
{
  int   *m_data;
  int    m_size;
public:
    // there constructor, destructor, some methods
    int Get(int* &_null_pointer)
    {
        if(!_null_pointer)
        {
            _null_pointer = new int [m_size];
            memcpy(_null_pointer, m_data, m_size * sizeof(int));
            return m_size;
        }
       return 0;
    }
}; 

example

Array<float> array;
float  *n_data = NULL;
int     data_size;
if(data_size = array.Get(n_data))
{     // work with array    }

delete [] n_data;

example for int

IntArray   array;
int       *n_data = NULL;
int        data_size;
if(data_size = array.Get(n_data))
{  // work with array  }

delete [] n_data;

Try to surround strings (hoot, story, article) with quotes ':

<div ng-repeat = "data in comments">
    <div ng-if="data.type == 'hoot' ">
        //different template with hoot data
    </div>
    <div ng-if="data.type == 'story' ">
        //different template with story data
    </div>
    <div ng-if="data.type == 'article' ">
        //different template with article data
    </div> 
</div>

 mylist=["ABA", "CAA", "ADA"]
 results=[]
 for item in mylist:
     buffer=[]
     for char in item:
         if char not in buffer:
             buffer.append(char)
     results.append("".join(buffer))
    
 print(results)

 output
 ABA
 CAA
 ADA
 ['AB', 'CA', 'AD']

I did not test the following snippet... hopefully it will point you towards the right direction:

    var jsreader = new JsonTextReader(new StringReader(stringData));
    var json = (JObject)new JsonSerializer().Deserialize(jsreader);
    var tableRows = from p in json["items"]
                 select new
                 {
                     Name = (string)p["Name"],
                     Age = (int)p["Age"],
                     Job = (string)p["Job"]
                 };

I can't repro, but I suspect that in your actual code there is a constraint somewhere that T : class - you need to propagate that to make the compiler happy, for example (hard to say for sure without a repro example):

public class Derived<SomeModel> : Base<SomeModel> where SomeModel : class, IModel
                                                                    ^^^^^
                                                                 see this bit

Working tree

Your working tree are the files that you are currently working on.

Git index

• The git "index" is where you place files you want commit to the git repository.

• The index is also known as cache, directory cache, current directory cache, staging area, staged files.

• Before you "commit" (checkin) files to the git repository, you need to first place the files in the git "index".

• The index is not the working directory: you can type a command such as git status, and git will tell you what files in your working directory have been added to the git index (for example, by using the git add filename command).

• The index is not the git repository: files in the git index are files that git would commit to the git repository if you used the git commit command.

In your code: $parts = array_map('trim', explode(':', $line_of_text, 2)); You have ":" as separator. If you use another separator in file, then you will get an "Undefined offset: 1" but not "Undefined offset: 0" All information will be in $parts[0] but no information in $parts[1] or [2] etc. Try to echo $part[0]; echo $part[1]; you will see the information.

@Transient complies with your needs.

You cannot use WHILE like that; see: mysql DECLARE WHILE outside stored procedure how?

You have to put your code in a stored procedure. Example:

CREATE PROCEDURE myproc()
BEGIN
    DECLARE i int DEFAULT 237692001;
    WHILE i <= 237692004 DO
        INSERT INTO mytable (code, active, total) VALUES (i, 1, 1);
        SET i = i + 1;
    END WHILE;
END

Fiddle: http://sqlfiddle.com/#!2/a4f92/1

Alternatively, generate a list of INSERT statements using any programming language you like; for a one-time creation, it should be fine. As an example, here's a Bash one-liner:

for i in {2376921001..2376921099}; do echo "INSERT INTO mytable (code, active, total) VALUES ($i, 1, 1);"; done

By the way, you made a typo in your numbers; 2376921001 has 10 digits, 237692200 only 9.

Just use event.getSource() frim within actionPerformed

Cast it to the component

for Ex, if you need combobox

JComboBox comboBox = (JComboBox) event.getSource();
JTextField txtField = (JTextField) event.getSource();

use appropriate api to get the value,

for Ex.

Object selected = comboBox.getSelectedItem();  etc.

I built this upon F.J.s excellent answer:

import re

def multiple_replacer(*key_values):
    replace_dict = dict(key_values)
    replacement_function = lambda match: replace_dict[match.group(0)]
    pattern = re.compile("|".join([re.escape(k) for k, v in key_values]), re.M)
    return lambda string: pattern.sub(replacement_function, string)

def multiple_replace(string, *key_values):
    return multiple_replacer(*key_values)(string)

One shot usage:

>>> replacements = (u"café", u"tea"), (u"tea", u"café"), (u"like", u"love")
>>> print multiple_replace(u"Do you like café? No, I prefer tea.", *replacements)
Do you love tea? No, I prefer café.

Note that since replacement is done in just one pass, "café" changes to "tea", but it does not change back to "café".

If you need to do the same replacement many times, you can create a replacement function easily:

>>> my_escaper = multiple_replacer(('"','\\"'), ('\t', '\\t'))
>>> many_many_strings = (u'This text will be escaped by "my_escaper"',
                       u'Does this work?\tYes it does',
                       u'And can we span\nmultiple lines?\t"Yes\twe\tcan!"')
>>> for line in many_many_strings:
...     print my_escaper(line)
... 
This text will be escaped by \"my_escaper\"
Does this work?\tYes it does
And can we span
multiple lines?\t\"Yes\twe\tcan!\"

Improvements:

• turned code into a function
• added multiline support
• fixed a bug in escaping
• easy to create a function for a specific multiple replacement

Enjoy! :-)

Classification

Is the assignment of predefined classes to new observations, based on learning from examples.

It is one of the key tasks in machine learning.

Clustering (or Cluster Analysis)

While popularly dismissed as "unsupervised classification" it is quite different.

In contrast to what many machine learners will teach you, it is not about assigning "classes" to objects, but without having them predefined. This is the very limited view of people who did too much classification; a typical example of if you have a hammer (classifier), everything looks like a nail (classification problem) to you. But it is also why classification people do not get a hang of clustering.

Instead, consider it as structure discovery. The task of clustering is to find structure (e.g. groups) in your data that you did not know before. Clustering has been successful if you learned something new. It failed, if you only got the structure you already knew.

Cluster analysis is a key task of data mining (and the ugly duckling in machine-learning, so don't listen to machine learners dismissing clustering).

"Unsupervised learning" is somewhat an Oxymoron

This has been iterated up and down the literature, but unsupervised learning is bllsht. It does not exist, but it is an oxymoron like "military intelligence".

Either the algorithm learns from examples (then it is "supervised learning"), or it does not learn. If all the clustering methods are "learning", then computing the minimum, maximum and average of a data set is "unsupervised learning", too. Then any computation "learned" its output. Thus the term 'unsupervised learning' is totally meaningless, it means everything and nothing.

Some "unsupervised learning" algorithms do, however, fall into the optimization category. For example k-means is a least-squares optimization. Such methods are all over statistics, so I don't think we need to label them "unsupervised learning", but instead should continue to call them "optimization problems". It's more precise, and more meaningful. There are plenty of clustering algorithms who do not involve optimization, and who do not fit into machine-learning paradigms well. So stop squeezing them in there under the umbrella "unsupervised learning".

There is some "learning" associated with clustering, but it is not the program that learns. It is the user that is supposed to learn new things about his data set.

I do this often and use a simple 5 line prototype that accepts varargs. It is fast and works everywhere.

As far as I read manual pages, scanf says that 'l' length modifier indicates (in case of floating points) that the argument is of type double rather than of type float, so you can have 'lf, le, lg'.

As for printing, officially, the manual says that 'l' applies only to integer types. So it might be not supported on some systems or by some standards. For instance, I get the following error message when compiling with gcc -Wall -Wextra -pedantic

a.c:6:1: warning: ISO C90 does not support the ‘%lf’ gnu_printf format [-Wformat=]

So you may want to doublecheck if your standard supports the syntax.

To conclude, I would say that you read with '%lf' and you print with '%f'.

The d3.js visualization examples I've been replicating on my local machine.. which import .JSON data.. all work fine on Mozilla Firefox browser; and on Chrome I get the cross-origins restrictions error. It's a weird thing how there's no issue with importing a local javascript file, but try loading a JSON and the browser gets nervous. There should at least be some setting to let the user over-ride it, the way pop-ups are blocked but I get to see an indication and a choice to unblock them.. no reason to be so Orwellian about the matter. Users shouldn't be treated as too naive to know what's best for them.

So I suggest using Firefox browser if you're working locally. And I hope people don't freak out over this and start bombing Mozilla to enforce cross-origin restrictions for local files.

As an aside to what folks have been posting here, I've heard that concatenation can be much faster than join in modern javascript vms. Meaning:

var a = 
[ "hey man, this is on a line",
  "and this is on another",
  "and this is on a third"
].join('\n');

Will be slower than:

var a = "hey man, this is on a line\n" + 
        "and this is on another\n" +
        "and this is on a third";    

In certain cases. http://jsperf.com/string-concat-versus-array-join/3

As another aside, I find this one of the more appealing features in Coffeescript. Yes, yes, I know, haters gonna hate.

html = '''
       <strong>
         cup of coffeescript
       </strong>
       '''

Its especially nice for html snippets. I'm not saying its a reason to use it, but I do wish it would land in ecma land :-(.

101 Word Intro

Camel is a framework with a consistent API and programming model for integrating applications together. The API is based on theories in Enterprise Integration Patterns - i.e., bunch of design patterns that tend to use messaging. It provides out of the box implementations of most of these patterns, and additionally ships with over 200 different components you can use to easily talk to all kinds of other systems. To use Camel, first write your business logic in POJOs and implement simple interfaces centered around messages. Then use Camel’s DSL to create "Routes" which are sets of rules for gluing your application together.

Extended Intro

On the surface, Camel's functionality rivals traditional Enterprise Service Bus products. We typically think of a Camel Route being a "mediation" (aka orchestration) component that lives on the server side, but because it's a Java library it’s easy to embed and it can live on a client side app just as well and help you integrate it with point to point services (aka choreography). You can even take your POJOs that process the messages inside the Camel route and easily spin them off into their own remote consumer processes, e.g. if you needed to scale just one piece independently. You can use Camel to connect routes or processors through any number of different remote transport/protocols depending on your needs. Do you need an extremely efficient and fast binary protocol, or one that is more human readable and easy to debug? What if you wanted to switch? With Camel this is usually as easy as changing a line or two in your route and not changing any business logic at all. Or you could support both - you’re free to run many Routes at once in a Camel Context.

You don't really need to use Camel for simple applications that are going to live in a single process or JVM - it would be overkill. But it's not conceptually any more difficult than code you may write yourself. And if your requirements change, the separation of business logic and glue code makes it easier to maintain over time. Once you learn the Camel API, it is easy to use it like a Swiss-Army knife and apply it quickly in many different contexts to cut down on the amount of custom code you’d otherwise have to write. You can learn one flavor - the Java DSL, for example, a fluent API that's easy to chain together - and pick up the other flavors easily.

Overall Camel is a great fit if you are trying to do microservices. I have found it invaluable for evolutionary architecture, because you can put off a lot of the difficult, "easy-to-get-wrong" decisions about protocols, transports and other system integration problems until you know more about your problem domain. Just focus on your EIPs and core business logic and switch to new Routes with the "right" components as you learn more.

Here is a very simple answer to this(only one line).

You can do that after you added the 'n' column into your df as follows.

import pandas as pd
df = pd.DataFrame({'l':['a','b','c','d'], 'v':[1,2,1,2]})
df['n'] = 0

df
    l   v   n
0   a   1   0
1   b   2   0
2   c   1   0
3   d   2   0

# here you can add the below code and it should work.
df = df[list('nlv')]
df

    n   l   v
0   0   a   1
1   0   b   2
2   0   c   1
3   0   d   2



However, if you have words in your columns names instead of letters. It should include two brackets around your column names. 

import pandas as pd
df = pd.DataFrame({'Upper':['a','b','c','d'], 'Lower':[1,2,1,2]})
df['Net'] = 0
df['Mid'] = 2
df['Zsore'] = 2

df

    Upper   Lower   Net Mid Zsore
0   a       1       0   2   2
1   b       2       0   2   2
2   c       1       0   2   2
3   d       2       0   2   2

# here you can add below line and it should work 
df = df[list(('Mid','Upper', 'Lower', 'Net','Zsore'))]
df

   Mid  Upper   Lower   Net Zsore
0   2   a       1       0   2
1   2   b       2       0   2
2   2   c       1       0   2
3   2   d       2       0   2

From a quick read of the previous answers, they look correct, but it doesn't look like anyone mentioned the new configuration facilities in Visual Studio 2008. It still uses app.config (copied at compile time to YourAppName.exe.config), but there is a UI widget to set properties and specify their types. Double-click Settings.settings in your project's "Properties" folder.

The best part is that accessing this property from code is typesafe - the compiler will catch obvious mistakes like mistyping the property name. For example, a property called MyConnectionString in app.config would be accessed like:

string s = Properties.Settings.Default.MyConnectionString;

I had the same problem. The answers got me on the right track. So the problem is that functions marked with async don't return a task of the function itself as expected (but another continuation task of the function).

So its the "await"and "async" keywords that screws thing up. The simplest solution then is simply to remove them. Then it works as expected. As in:

static void Main(string[] args)
{
    Console.WriteLine("Foo called");
    var result = Foo(5);

    while (result.Status != TaskStatus.RanToCompletion)
    {
        Console.WriteLine("Thread ID: {0}, Status: {1}", Thread.CurrentThread.ManagedThreadId, result.Status);
        Task.Delay(100).Wait();
    }

    Console.WriteLine("Result: {0}", result.Result);
    Console.WriteLine("Finished.");
    Console.ReadKey(true);
}

private static Task<string> Foo(int seconds)
{
    return Task.Run(() =>
    {
        for (int i = 0; i < seconds; i++)
        {
            Console.WriteLine("Thread ID: {0}, second {1}.", Thread.CurrentThread.ManagedThreadId, i);
            Task.Delay(TimeSpan.FromSeconds(1)).Wait();
        }

        return "Foo Completed.";
    });
}

Which outputs:

Delegate :- Create

@protocol addToCartDelegate <NSObject>

-(void)addToCartAction:(ItemsModel *)itemsModel isAdded:(BOOL)added;

@end

Send and please assign delegate to view you are sending data

[self.delegate addToCartAction:itemsModel isAdded:YES];

If you have Jackson integeration with your application to serialize your bean to JSON format, then you can use Jackson anotation @JsonFormat to format your date to specified format.
In your case if you need your date into yyyy-MM-dd format you need to specify @JsonFormat above your field on which you want to apply this format.

For Example :

public class Subject {

     private String uid;
     private String number;
     private String initials;

     @JsonFormat(pattern="yyyy-MM-dd")
     private Date dateOfBirth;  

     //Other Code  

}  

From Docs :

annotation used for configuring details of how values of properties are to be serialized.

Hope this helps.

here is the snippet to set token, before that make sure the access type should be set to offline

if (isset($_GET['code'])) {
  $client->authenticate();
  $_SESSION['access_token'] = $client->getAccessToken();
}

To refresh token

$google_token= json_decode($_SESSION['access_token']);
$client->refreshToken($google_token->refresh_token);

this will refresh your token, you have to update it in session for that you can do

 $_SESSION['access_token']= $client->getAccessToken()

>>> a = 'ZENOVW'
>>> b = sorted(a)
>>> print b
['E', 'N', 'O', 'V', 'W', 'Z']

sorted returns a list, so you can make it a string again using join:

>>> c = ''.join(b)

which joins the items of b together with an empty string '' in between each item.

>>> print c
'ENOVWZ'

There are two issues:

1. Getting the current coordinates (longitude, latitude, perhaps altitude) based on some external signals received by your device, and
2. Deriving a human-readable position (address) from the coordinates.

To get the coordinates you don't need the Internet. GPS is satellite-based. But to derive street/city information from the coordinates, you'd need either to implement the map and the corresponding algorithms yourself on the device (a lot of work!) or to rely on proven services, e.g. by Google, in which case you'd need an Internet connection.

As of recently, Google allows for caching the maps, which would at least allow you to show your current position on the map even without a data connection, provided, you had cached the map in advance, when you could access the Internet.

Try Java SE Runtime Environment 8. It fixed it for me.

I think the better answer for this questions is

array_diff() 

because it Compares array against one or more other arrays and returns the values in array that are not present in any of the other arrays.

Whereas

array_intersect() returns an array containing all the values of array that are present in all the arguments. Note that keys are preserved.

You could even try this expression ^[a-zA-Z\\s]*$ for checking a string with only letters and spaces (nothing else).

For me it worked. Hope it works for you as well.

Or go through this piece of code once:

    CharSequence inputStr = expression;
    Pattern pattern = Pattern.compile(new String ("^[a-zA-Z\\s]*$"));
    Matcher matcher = pattern.matcher(inputStr);
    if(matcher.matches())
    {
         //if pattern matches
    }
    else
    {
         //if pattern does not matches
    }

Sounds like you only installed the MySQL Client Tools (MySQL Workbench). You have to install the MySQL Database server, configure and start it.

You probably want the MySQL Community Server download.

This also works....sometimes you may want to construct the definition of the parameters outside of the actual EXEC call.

DECLARE @Parmdef nvarchar (500)
DECLARE @SQL nvarchar (max)
DECLARE @xTxt1  nvarchar (100) = 'test1'
DECLARE @xTxt2  nvarchar (500) = 'test2' 
SET @parmdef = '@text1 nvarchar (100), @text2 nvarchar (500)'
SET @SQL = 'PRINT @text1 + '' '' + @text2'
EXEC sp_executeSQL @SQL, @Parmdef, @xTxt1, @xTxt2

PizzaChange=float(input("What would you like the new price for all standard pizzas to be? "))      
for i,price in enumerate(PriceList):
  PriceList[i] = PizzaChange + 3*int(i>=7)

Useful to quickly print entries in a HashMap

System.out.println(Arrays.toString(map.entrySet().toArray()));

Check your code behind file name and Inherits property on the @Page directive, make sure they both match.

A normal math answer.

Understanding that a floating point number is implemented as some bits representing the exponent and the rest, most for the digits (in the binary system), one has the following situation:

With a high exponent, say 10²³ if the least significant bit is changed, a large difference between two adjacent distinghuishable numbers appear. Furthermore the base 2 decimal point makes that many base 10 numbers can only be approximated; 1/5, 1/10 being endless numbers.

So in general: floating point numbers should not be used if you care about significant digits. For monetary amounts with calculation, e,a, best use BigDecimal.

For physics floating point doubles are adequate, floats almost never. Furthermore the floating point part of processors, the FPU, can even use a bit more precission internally.

jQuery has some issues loading binary data using AJAX requests, as it does not yet implement some HTML5 XHR v2 capabilities, see this enhancement request and this discussion

Given that, you have one of two solutions:

First solution, abandon JQuery and use XMLHTTPRequest

Go with the native HTMLHTTPRequest, here is the code to do what you need

  var req = new XMLHttpRequest();
  req.open("GET", "/file.pdf", true);
  req.responseType = "blob";

  req.onload = function (event) {
    var blob = req.response;
    console.log(blob.size);
    var link=document.createElement('a');
    link.href=window.URL.createObjectURL(blob);
    link.download="Dossier_" + new Date() + ".pdf";
    link.click();
  };

  req.send();

Second solution, use the jquery-ajax-native plugin

The plugin can be found here and can be used to the XHR V2 capabilities missing in JQuery, here is a sample code how to use it

$.ajax({
  dataType: 'native',
  url: "/file.pdf",
  xhrFields: {
    responseType: 'blob'
  },
  success: function(blob){
    console.log(blob.size);
      var link=document.createElement('a');
      link.href=window.URL.createObjectURL(blob);
      link.download="Dossier_" + new Date() + ".pdf";
      link.click();
  }
});

It looks like there is an extra curly bracket in the code.

function () {
    if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
        document.getElementById("content").innerHTML = xmlhttp.responseText;
    }
// extra bracket }
xmlhttp.open("GET", "data/" + id + ".html", true);
xmlhttp.send();
}

Note that I did find one way to do it, but this looks more like material for The Daily WTF:

catch (Exception ex)
{
    switch (ex.GetType().Name)
    {
        case "System.FormatException":
        case "System.OverflowException":
            WebId = Guid.Empty;
            break;
        default:
            throw;
    }
}

Under Windows 10, the Task Manager can show you cumulative CPU hours. Just head to the "App history" tab and "Delete usage history". Now leave things running for an hour or two:

What this does NOT do is break down usage in browsers by tab. Quite often inactive tabs will do a tremendous amount of work, with each open tab using energy and slowing your PC.

The other answers in my case did not work. I had to restart windows before I could debug the application again.

Visual Studio For Mac

None of the other solutions worked on Visual Studio for Mac

If you are using NUnit, you can add a small .NET Console Project to your solution, and then reference the project you wish to test in the References of that new Console Project.

Whatever you were doing in your [Test()] methods can be done in the Main of the console application in this fashion:

class MainClass
{
    public static void Main(string[] args)
    {
        Console.WriteLine("Console");

        // Reproduce the unit test
        var classToTest = new ClassToTest();
        var expected = 42;
        var actual = classToTest.MeaningOfLife();
        Console.WriteLine($"Pass: {expected.Equals(actual)}, expected={expected}, actual={actual}");
    }
}

You are free to use Console.Write and Console.WriteLine in your code under these circumstances.

You could use dplyr::mutate_if() to convert all character columns or dplyr::mutate_at() for select named character columns to factors:

library(dplyr)

# all character columns to factor:
df <- mutate_if(df, is.character, as.factor)

# select character columns 'char1', 'char2', etc. to factor:
df <- mutate_at(df, vars(char1, char2), as.factor)

Thanks RedFilter for providing excellent solution to the bugging issue of sorting nullable datetime field.

I am using SQL Server database for my project.

Changing the datetime null value to '1' does solves the problem of sorting for datetime datatype column. However if we have column with other than datetime datatype then it fails to handle.

To handle a varchar column sort, I tried using 'ZZZZZZZ' as I knew the column does not have values beginning with 'Z'. It worked as expected.

On the same lines, I used max values +1 for int and other data types to get the sort as expected. This also gave me the results as were required.

However, it would always be ideal to get something easier in the database engine itself that could do something like:

Order by Col1 Asc Nulls Last, Col2 Asc Nulls First

3. <div [style.background-image]="'url(' + your_property + ')' | safe: 'style'"></div>

After @Arvis reply i decided to dig even deeper and I've written a tech article about this here: http://www.andreabaccega.com/blog/2015/08/16/how-to-avoid-fragments-overlapping-due-to-backstack-nightmare-in-android/

For the lazy developers around. My solution consists in always adding the transactions to the backstack and perform an extra FragmentManager.popBackStackImmediate() when needed (automatically).

The code is very few lines of code and, in my example, I wanted to skip from C to A without jumping back to "B" if the user didn't went deeper in the backstack (ex from C navigates to D).

Hence the code attached would work as follow A -> B -> C (back) -> A & A -> B -> C -> D (back) -> C (back) -> B (back) -> A

where

fm.beginTransaction().replace(R.id.content, new CFragment()).commit()

were issued from "B" to "C" as in the question.

Ok,Ok here is the code :)

public static void performNoBackStackTransaction(FragmentManager fragmentManager, String tag, Fragment fragment) {
  final int newBackStackLength = fragmentManager.getBackStackEntryCount() +1;

  fragmentManager.beginTransaction()
      .replace(R.id.content, fragment, tag)
      .addToBackStack(tag)
      .commit();

  fragmentManager.addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
    @Override
    public void onBackStackChanged() {
      int nowCount = fragmentManager.getBackStackEntryCount();
      if (newBackStackLength != nowCount) {
        // we don't really care if going back or forward. we already performed the logic here.
        fragmentManager.removeOnBackStackChangedListener(this);

        if ( newBackStackLength > nowCount ) { // user pressed back
          fragmentManager.popBackStackImmediate();
        }
      }
    }
  });
}

The answer to my comment above on the Original Question makes me think this is all he wants:

loopnum = 0
word = 'afrykanerskojezyczny'
wordlist = ['afrykanerskojezycznym','afrykanerskojezyczni','nieafrykanerskojezyczni']
for i in wordlist:
    wordlist[loopnum] = word
    loopnum += 1

This will do the following:

For every value in wordlist, set that value of the wordlist to the origional code.

All you have to do is put this piece of code where you need to change wordlist, making sure you store the words you need to change in wordlist, and that the original word is correct.

Hope this helps!

Found something like that:

//javascript:
function playSound( url ){   
  document.getElementById("sound").innerHTML="<embed src='"+url+"' hidden=true autostart=true loop=false>";
}
