The subprocess module is the preferred way of running other programs from Python -- much more flexible and nicer to use than os.system.

import subprocess
#subprocess.check_output(['ls', '-l'])  # All that is technically needed...
print(subprocess.check_output(['ls', '-l']))

This works from my Windows 10's cmd.exe prompt

powershell -ExecutionPolicy Bypass -Command "Import-Module C:\Users\william\ps1\TravelBook; Get-TravelBook Hawaii"

This example shows

1. how to chain multiple commands
2. how to import module with module path
3. how to run a function defined in the module
4. No need for those fancy "&".

If the HTTP Connection doesn't timeout, You can implement the timeout checker in the background thread itself (AsyncTask, Service, etc), the following class is an example for Customize AsyncTask which timeout after certain period

public abstract class AsyncTaskWithTimer<Params, Progress, Result> extends
    AsyncTask<Params, Progress, Result> {

private static final int HTTP_REQUEST_TIMEOUT = 30000;

@Override
protected Result doInBackground(Params... params) {
    createTimeoutListener();
    return doInBackgroundImpl(params);
}

private void createTimeoutListener() {
    Thread timeout = new Thread() {
        public void run() {
            Looper.prepare();

            final Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {

                    if (AsyncTaskWithTimer.this != null
                            && AsyncTaskWithTimer.this.getStatus() != Status.FINISHED)
                        AsyncTaskWithTimer.this.cancel(true);
                    handler.removeCallbacks(this);
                    Looper.myLooper().quit();
                }
            }, HTTP_REQUEST_TIMEOUT);

            Looper.loop();
        }
    };
    timeout.start();
}

abstract protected Result doInBackgroundImpl(Params... params);
}

A Sample for this

public class AsyncTaskWithTimerSample extends AsyncTaskWithTimer<Void, Void, Void> {

    @Override
    protected void onCancelled(Void void) {
        Log.d(TAG, "Async Task onCancelled With Result");
        super.onCancelled(result);
    }

    @Override
    protected void onCancelled() {
        Log.d(TAG, "Async Task onCancelled");
        super.onCancelled();
    }

    @Override
    protected Void doInBackgroundImpl(Void... params) {
        // Do background work
        return null;
    };
 }

It depends on how you access the data:

Go for Option 1:

• If you use most of the fields on most of your accesses.
• If there is variance on possible keys

Go for Option 2:

• If you use just single fields on most of your accesses.
• If you always know which fields are available

P.S.: As a rule of the thumb, go for the option which requires fewer queries on most of your use cases.

Step-by-Step way to do this:

1. Install Android SDK
2. Start the emulator by going to $SDK_root/emulator.exe
3. Go to command prompt and go to the directory $SDK_root/platform-tools (or else add the path to windows environment)
4. Type in the command adb install
5. Bingo. Your app should be up and running on the emulator

Try this:

tar -zxvf file.tar.gz

Looks like you're trying to execute a windows file (.exe) Surely you ought to be using powershell. Anyway on a Linux bash shell a simple one-liner will suffice.

[/home/$] for filename in /Data/*.txt; do for i in {0..3}; do ./MyProgam.exe  Data/filenameLogs/$filename_log$i.txt; done done

Or in a bash

#!/bin/bash

for filename in /Data/*.txt; 
   do
     for i in {0..3}; 
       do ./MyProgam.exe Data/filename.txt Logs/$filename_log$i.txt; 
     done 
 done

A BusyBox port for Windows has both a diff and patch command, but they only support unified format.

Try this one.

public static string GetFQDN()
{
    string domainName = NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName;
    string hostName = Dns.GetHostName();
    string fqdn;
    if (!hostName.Contains(domainName))
        fqdn = hostName + "." +domainName;
    else
        fqdn = hostName;

    return fqdn;
}

There has been a lot of great answers already, but most of them won't work with array of primitives (like int[], long[], char[], byte[], etc.)

In Java 8 and above, you can box the array with:

Integer[] boxedArr = Arrays.stream(arr).boxed().toArray(Integer[]::new);

Then convert to set using stream:

Stream.of(boxedArr).collect(Collectors.toSet());

How about this

$.validate.addMethod(cb_selectone,
                   function(value,element){
                           if(element.length>0){
                               for(var i=0;i<element.length;i++){
                                if($(element[i]).val('checked')) return true;
                               }
                           return false;
                           }
                            return false;
                  },
                  'Please select a least one')

Now you ca do

$.validate({rules:{checklist:"cb_selectone"}});

You can even go further a specify the minimum number to select with a third param in the callback function.I have not tested it yet so tell me if it works.

The CSS specification requires that position:fixed be anchored to the viewport, not the containing positioned element.

If you must specify your coordinates relative to a parent, you will have to use JavaScript to find the parent's position relative to the viewport first, then set the child (fixed) element's position accordingly.

ALTERNATIVE: Some browsers have sticky CSS support which limits an element to be positioned within both its container and the viewport. Per the commit message:

sticky ... constrains an element to be positioned inside the intersection of its container box, and the viewport.

A stickily positioned element behaves like position:relative (space is reserved for it in-flow), but with an offset that is determined by the sticky position. Changed isInFlowPositioned() to cover relative and sticky.

Depending on your design goals, this behavior may be helpful in some cases. It is currently a working draft, and has decent support, aside from table elements. position: sticky still needs a -webkit prefix in Safari.

See caniuse for up-to-date stats on browser support.

Unfortunately, the old xkcd comic isn't completely up to date anymore.

Since Python 3.0 you have to write:

print("Hello, World!")

And someone has still to write that antigravity library :(

"Optional parameter" means "type of this parameter is optional". It does not mean "This parameter is optional and, therefore, can be ignored when you call the function".

The term "optional parameter" appears to be confusing. To clarify, it's more accurate to say "optional type parameter" instead of "optional parameter" as the word "optional" here is only meant to describe the type of parameter value and nothing else.

You can just modify any xml files in /res folder and even just add a space and save, it will be regenerated.

ASP.NET 4 introduces a new code nugget syntax <%: %>. Essentially, <%: foo %> translates to <%= HttpUtility.HtmlEncode(foo) %>. The team is trying to get developers to use <%: %> instead of <%= %> wherever possible to prevent XSS.

However, this introduces the problem that if a code nugget already encodes its result, the <%: %> syntax will re-encode it. This is solved by the introduction of the IHtmlString interface (new in .NET 4). If the foo() in <%: foo() %> returns an IHtmlString, the <%: %> syntax will not re-encode it.

MVC 2's helpers return MvcHtmlString, which on ASP.NET 4 implements the interface IHtmlString. Therefore when developers use <%: Html.*() %> in ASP.NET 4, the result won't be double-encoded.

Edit:

An immediate benefit of this new syntax is that your views are a little cleaner. For example, you can write <%: ViewData["anything"] %> instead of <%= Html.Encode(ViewData["anything"]) %>.

Postgres Enterprise Manager from EnterpriseDB is probably the most advanced you'll find. It includes all the features of pgAdmin, plus monitoring of your hosts and database servers, predictive reporting, alerting and a SQL Profiler.

You could use a for loop to print the []Project as shown in @VonC excellent answer.

package main

import "fmt"

type Project struct{ name string }

func main() {
    projects := []Project{{"p1"}, {"p2"}}
    for i := range projects {
        p := projects[i]
        fmt.Println(p.name) //p1, p2
    }
}

This is the real life scenario

Imagine this scenario

1. You have a global CSS file that sets visual aspects of your site globally.
2. You (or others) use inline styles on elements themselves which is usually very bad practice.

In this case you could set certain styles in your global CSS file as important, thus overriding inline styles set directly on elements.

Actual real world example?

This kind of scenario usually happens when you don't have total control over your HTML. Think of solutions in SharePoint for instance. You'd like your part to be globally defined (styled), but some inline styles you can't control are present. !important makes such situations easier to deal with.

Other real life scenarios would also include some badly written jQuery plugins that also use inline styles...

I suppose you got the idea by now and can come up with some others as well.

When do you decide to use !important?

I suggest you don't use !important unless you can't do it any other way. Whenever it's possible to avoid it, avoid it. Using lots of !important styles will make maintenance a bit harder, because you break the natural cascading in your stylesheets.

Remember if your route is name-spaced, Like:

product GET  /products/:id(.:format)  spree/products#show

Then try :

helper.link_to("test", app.spree.product_path(Spree::Product.first), method: :get)

output

Spree::Product Load (0.4ms)  SELECT  "spree_products".* FROM "spree_products"  WHERE "spree_products"."deleted_at" IS NULL  ORDER BY "spree_products"."id" ASC LIMIT 1
=> "<a data-method=\"get\" href=\"/products/this-is-the-title\">test</a>" 

Try this

        self.opener.location.reload(); 

Open the parent of a current window and reload the location.

You should really rethink your approach to this issue. Using a well crafted selector and attaching the class may be a more elegant solution to this approach. As far as I know you cannot modify external CSS.

One line of CSS is enough using hue-rotate filter. You can change their sizes with transform: scale() as well.

.checkbox { filter: hue-rotate(0deg) }

Codepen

.c1 { filter: hue-rotate(0deg)   }
.c2 { filter: hue-rotate(30deg)  }
.c3 { filter: hue-rotate(60deg)  }
.c4 { filter: hue-rotate(90deg)  }
.c5 { filter: hue-rotate(120deg) }
.c6 { filter: hue-rotate(150deg) }
.c7 { filter: hue-rotate(180deg) }
.c8 { filter: hue-rotate(210deg) }
.c9 { filter: hue-rotate(240deg) }

input[type=checkbox] {
  transform: scale(2);
  margin: 10px;
  cursor: pointer;
}

/* Prevent cursor being `text` between checkboxes */
body { cursor: default }

<input type="checkbox" class="c1" />
<input type="checkbox" class="c2" />
<input type="checkbox" class="c3" />
<input type="checkbox" class="c4" />
<input type="checkbox" class="c5" />
<input type="checkbox" class="c6" />
<input type="checkbox" class="c7" />
<input type="checkbox" class="c8" />
<input type="checkbox" class="c9" />

I would like to point out that the solutions given above do not "just work" with non-trivial queries. One issue I came across were more complicated types, such as pgsql ARRAYs causing issues. I did find a solution that for me, did just work even with pgsql ARRAYs:

borrowed from: https://gist.github.com/gsakkis/4572159

The linked code seems to be based on an older version of SQLAlchemy. You'll get an error saying that the attribute _mapper_zero_or_none doesn't exist. Here's an updated version that will work with a newer version, you simply replace _mapper_zero_or_none with bind. Additionally, this has support for pgsql arrays:

Tested to two levels of nested arrays.

I find it easier to access it by doing the following:

        for (int i = 0; i < Table.Rows.Count-1; i++) //Looping through rows
        {
            var myValue = Table.Rows[i]["MyFieldName"]; //Getting my field value

        }

In my case this (a with caret) occurred in code I generated from visual studio using my own tool for generating code. It was easy to solve:

Select single spaces ( ) in the document. You should be able to see lots of single spaces that are looking different from the other single spaces, they are not selected. Select these other single spaces - they are the ones responsible for the unwanted characters in the browser. Go to Find and Replace with single space ( ). Done.

PS: It's easier to see all similar characters when you place the cursor on one or if you select it in VS2017+; I hope other IDEs may have similar features

Try mvn clean install eclipse:eclipse -Dwtpversion=2.0 command on DOS command prompt. Suggesting you because , It worked for me!!

To fix your issue, i have made few changes in bla.js and it is working,

var foo= function (req, res, next) {
  console.log('inside foo');
  return ("foo");
}

var  bar= function(req, res, next) {
  this.foo();
}
module.exports = {bar,foo};

and no modification in app.js

var bla = require('./bla.js');
console.log(bla.bar());

You can create an array dynamically in this way:

 static void Main()
    {
        // Create a string array 2 elements in length:
        int arrayLength = 2;
        Array dynamicArray = Array.CreateInstance(typeof(int), arrayLength);
        dynamicArray.SetValue(234, 0);                              //  ? a[0] = 234;
        dynamicArray.SetValue(444, 1);                              //  ? a[1] = 444;
        int number = (int)dynamicArray.GetValue(0);                      //  ? number = a[0];


        int[] cSharpArray = (int[])dynamicArray;
        int s2 = cSharpArray[0];

    }

Well you can have each form go to to a different page. (which is preferable)

Or have a different value for the a certain input and base posts on that:

switch($_POST['submit']) {
    case 'login': 
    //...
    break;
    case 'register':
    //...
    break;
}

If you want to order by count (sound simple but i can`t found an answer on stack of how to do that) you can do:

        SELECT town, count(town) as total FROM user
        GROUP BY town ORDER BY total DESC

I had this problem to install laravel/lumen.

It can be resolved with the following command:

$ sudo chown -R $USER ~/.composer/

I know this is an old question, but I have just had a similar problem and I think what I did would work for you too.

I used the to_csv() method and wrote to stdout:

import sys

paramdata.to_csv(sys.stdout)

This should dump the whole dataframe whether it's nicely-printable or not, and you can use the to_csv parameters to configure column separators, whether the index is printed, etc.

Edit: It is now possible to use None as the target for .to_csv() with similar effect, which is arguably a lot nicer:

paramdata.to_csv(None)

|| is the conditional OR operator in C#

You probably had a hard time finding it because it's difficult to search for something whose name you don't know. Next time try doing a Google search for "C# Operators" and look at the logical operators.

Here is a list of C# operators.

My code is:

if (title == "User greeting" || "User name") {do stuff};

and my error is:

Error 1 Operator '||' cannot be applied to operands of type 'bool' and 'string' C:\Documents and Settings\Sky View Barns\My Documents\Visual Studio 2005\Projects\FOL Ministry\FOL Ministry\Downloader.cs 63 21 FOL Ministry

You need to do this instead:

if (title == "User greeting" || title == "User name") {do stuff};

The OR operator evaluates the expressions on both sides the same way. In your example, you are operating on the expression title == "User greeting" (a bool) and the expression "User name" (a string). These can't be combined directly without a cast or conversion, which is why you're getting the error.

In addition, it is worth noting that the || operator uses "short-circuit evaluation". This means that if the first expression evaluates to true, the second expression is not evaluated because it doesn't have to be - the end result will always be true. Sometimes you can take advantage of this during optimization.

One last quick note - I often write my conditionals with nested parentheses like this:

if ((title == "User greeting") || (title == "User name")) {do stuff};

This way I can control precedence and don't have to worry about the order of operations. It's probably overkill here, but it's especially useful when the logic gets complicated.

Add a reference to System.Web.dll and then you can use the System.Web.HtmlUtility class

Here is an example of the difference, as a spark-shell session:

First, some data - two lines of text:

val rdd = sc.parallelize(Seq("Roses are red", "Violets are blue"))  // lines

rdd.collect

    res0: Array[String] = Array("Roses are red", "Violets are blue")

Now, map transforms an RDD of length N into another RDD of length N.

For example, it maps from two lines into two line-lengths:

rdd.map(_.length).collect

    res1: Array[Int] = Array(13, 16)

But flatMap (loosely speaking) transforms an RDD of length N into a collection of N collections, then flattens these into a single RDD of results.

rdd.flatMap(_.split(" ")).collect

    res2: Array[String] = Array("Roses", "are", "red", "Violets", "are", "blue")

We have multiple words per line, and multiple lines, but we end up with a single output array of words

Just to illustrate that, flatMapping from a collection of lines to a collection of words looks like:

["aa bb cc", "", "dd"] => [["aa","bb","cc"],[],["dd"]] => ["aa","bb","cc","dd"]

The input and output RDDs will therefore typically be of different sizes for flatMap.

If we had tried to use map with our split function, we'd have ended up with nested structures (an RDD of arrays of words, with type RDD[Array[String]]) because we have to have exactly one result per input:

rdd.map(_.split(" ")).collect

    res3: Array[Array[String]] = Array(
                                     Array(Roses, are, red), 
                                     Array(Violets, are, blue)
                                 )

Finally, one useful special case is mapping with a function which might not return an answer, and so returns an Option. We can use flatMap to filter out the elements that return None and extract the values from those that return a Some:

val rdd = sc.parallelize(Seq(1,2,3,4))

def myfn(x: Int): Option[Int] = if (x <= 2) Some(x * 10) else None

rdd.flatMap(myfn).collect

    res3: Array[Int] = Array(10,20)

(noting here that an Option behaves rather like a list that has either one element, or zero elements)

The file object is a buffer. When you read from the buffer, that portion that you read is consumed (the read position is shifted forward). When you read through the entire file, the read position is at the end of the file (EOF), so it returns nothing because there is nothing left to read.

If you have to reset the read position on a file object for some reason, you can do:

f.seek(0)

Plain JavaScript:

You don't need jQuery to do something trivial like this. Just use the .removeAttribute() method.

Assuming you are just targeting a single element, you can easily use the following: (example)

document.querySelector('#target').removeAttribute('style');

If you are targeting multiple elements, just loop through the selected collection of elements: (example)

var target = document.querySelectorAll('div');
Array.prototype.forEach.call(target, function(element){
    element.removeAttribute('style');
});

Array.prototype.forEach() - IE9 and above / .querySelectorAll() - IE 8 (partial) IE9 and above.

OK - what you're missing is that its designed to be more industrial and serve many sites, so the config you want is probably:

/etc/apache2/sites-available/default

which on my system is linked to from /etc/apache2/sites-enabled/

if you want to have different sites with different options, copy the file and then change those...

Sending headers earlier than the normal course may have far reaching consequences. Below are just a few of them that happened to come to my mind at the moment:

1. While current PHP releases may have output buffering on, the actual production servers you will be deploying your code on are far more important than any development or testing machines. And they do not always tend to follow latest PHP trends immediately.

2. You may have headaches over inexplicable functionality loss. Say, you are implementing some kind payment gateway, and redirect user to a specific URL after successful confirmation by the payment processor. If some kind of PHP error, even a warning, or an excess line ending happens, the payment may remain unprocessed and the user may still seem unbilled. This is also one of the reasons why needless redirection is evil and if redirection is to be used, it must be used with caution.

3. You may get "Page loading canceled" type of errors in Internet Explorer, even in the most recent versions. This is because an AJAX response/json include contains something that it shouldn't contain, because of the excess line endings in some PHP files, just as I've encountered a few days ago.

4. If you have some file downloads in your app, they can break too, because of this. And you may not notice it, even after years, since the specific breaking habit of a download depends on the server, the browser, the type and content of the file (and possibly some other factors I don't want to bore you with).

5. Finally, many PHP frameworks including Symfony, Zend and Laravel (there is no mention of this in the coding guidelines but it follows the suit) and the PSR-2 standard (item 2.2) require omission of the closing tag. PHP manual itself (1,2), Wordpress, Drupal and many other PHP software I guess, advise to do so. If you simply make a habit of following the standard (and setup PHP-CS-Fixer for your code) you can forget the issue. Otherwise you will always need to keep the issue in your mind.

Bonus: a few gotchas (actually currently one) related to these 2 characters:

1. Even some well-known libraries may contain excess line endings after ?>. An example is Smarty, even the most recent versions of both 2.* and 3.* branch have this. So, as always, watch for third party code. Bonus in bonus: A regex for deleting needless PHP endings: replace (\s*\?>\s*)$ with empty text in all files that contain PHP code.

My Dark Color scheme for QtCreator is at:

Hope it is useful for someone.

i had got the same error. Actually i tried to override the flutter Old SDK Package with new Updated Package. so that error occurred.

i opened flutter sdk directory with VS Code and cleaned the project

use this code in VSCode cmd

git clean -dxf

then use git pull

This will vary depending on your architecture and how it treats basic data types. It will also depend on whether the system requires natural alignment.

In SQL Server Management Studio do the following:

1. Right Click on your database, choose properties
2. Go to the Options Page
3. In the Drop down at right labeled "Compatibility Level" choose "SQL Server 2005(90)" 3-1. choose "SQL Server 2008" if you receive a comparability error.
4. Go to the Files Page
5. Enter "sa" in the owner textbox. 5-1 or click on the ellipses(...) and choose a rightful owner.
6. Hit OK

after doing this, You will now be able to access the Database Diagrams.

There is a simplified solution from bootstrap here (where you don't need to create a new class): http://getbootstrap.com/examples/sticky-footer-navbar/

When you open that page, right click on a browser and "View Source" and open the sticky-footer-navbar.css file (http://getbootstrap.com/examples/sticky-footer-navbar/sticky-footer-navbar.css)

you can see that you only need this CSS

/* Sticky footer styles
-------------------------------------------------- */
html {
  position: relative;
  min-height: 100%;
}
body {
  /* Margin bottom by footer height */
  margin-bottom: 60px;
}
.footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  /* Set the fixed height of the footer here */
  height: 60px;
  background-color: #f5f5f5;
}

for this HTML

<html>
    ...
    <body>
        <!-- Begin page content -->
        <div class="container">
        </div>
        ...

        <footer class="footer">
        </footer>
    </body>
</html>

AVI to MPG (pick your extensions):

files = os.listdir('/input')
for sourceVideo in files:
    if sourceVideo[-4:] != ".avi"
        continue
    destinationVideo = sourceVideo[:-4] + ".mpg"
    cmdLine = ['mencoder', sourceVideo, '-ovc', 'copy', '-oac', 'copy', '-ss',
        '00:02:54', '-endpos', '00:00:54', '-o', destinationVideo]
    output1 = Popen(cmdLine, stdout=PIPE).communicate()[0]
    print output1
    output2 = Popen(['del', sourceVideo], stdout=PIPE).communicate()[0]
    print output2

I had the same error message, but these answers did not help. On a 4.3 nexus 7, I was using a user who was NOT the owner. I had uninstalled the older version but I kept getting the same message.

Solution: I had to login as the owner and go to Settings -> Apps, then swipe to the All tab. Scroll down to the very end of the list where the old versions are listed with a mark 'not installed'. Select it and press the 'settings' button in the top right corner and finally 'uninstall for all users'

It is the container of the Grid that is imposing on its width. In this case, that's a ListBoxItem, which is left-aligned by default. You can set it to stretch as follows:

<ListBox>
    <!-- other XAML omitted, you just need to add the following bit -->
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="HorizontalAlignment" Value="Stretch"/>
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox>

With your current requirement this would work :

    def start_html():
        return '<html>'

    def end_html():
        return '</html>'

    def print_html(text):
        text = str(text)
        text = text.replace('\n', '<br>')
        return '<p>' + str(text) + '</p>'
if __name__ == '__main__':
        webpage_data =  start_html()
        webpage_data += print_html("Hi Welcome to Python test page\n")
        webpage_data += fd.write(print_html("Now it will show a calculation"))
        webpage_data += print_html("30+2=")
        webpage_data += print_html(30+2)
        webpage_data += end_html()
        with open('index.html', 'w') as fd: fd.write(webpage_data)

open the index.html and you will see what you want

I think that all previous answers are correct, this below code is very valid specially if you have to update multiple rows at once, note: it's PL/SQL

DECLARE
    CURSOR myCursor IS 
      Select contacts.BusinessCountry 
      From contacts c WHERE c.Key = t.Key;
    ---------------------------------------------------------------------
BEGIN
    FOR resultValue IN myCursor LOOP
        Update tblindiantime t
        Set CountryName=resultValue.BusinessCountry 
        where t.key=resultValue.key;
    END LOOP;
END;

I wish this could help.

Try css:

.topcorner{
    position:absolute;
    top:10px;
    right: 10px;
 }

you can play with the top and right properties.

If you want to float the div even when you scroll down, just change position:absolute; to position:fixed;.

Hope it helps.

I am trying to test django rest api and its working for me:

def test_upload_file(self):
        filename = "/Users/Ranvijay/tests/test_price_matrix.csv"
        data = {'file': open(filename, 'rb')}
        client = APIClient()
        # client.credentials(HTTP_AUTHORIZATION='Token ' + token.key)
        response = client.post(reverse('price-matrix-csv'), data, format='multipart')

        print response
        self.assertEqual(response.status_code, status.HTTP_200_OK)

Numpy's r_ convenience function can also create evenly spaced lists with syntax np.r_[start:stop:steps]. If steps is a real number (ending on j), then the end point is included, equivalent to np.linspace(start, stop, step, endpoint=1), otherwise not.

>>> np.r_[-1:1:6j, [0]*3, 5, 6]
array([-1. , -0.6, -0.2,  0.2,  0.6,  1.])

You can also directly concatente other arrays and also scalars:

>>> np.r_[-1:1:6j, [0]*3, 5, 6]
array([-1. , -0.6, -0.2,  0.2,  0.6,  1. ,  0. ,  0. ,  0. ,  5. ,  6. ])

There are other ways to achieve this here: (Plot correlation matrix into a graph), but I like your version with the correlations in the boxes. Is there a way to add the variable names to the x and y column instead of just those index numbers? For me, that would make this a perfect solution. Thanks!

edit: I was trying to comment on the post by [Marc in the box], but I clearly don't know what I'm doing. However, I did manage to answer this question for myself.

if d is the matrix (or the original data frame) and the column names are what you want, then the following works:

axis(1, 1:dim(d)[2], colnames(d), las=2)
axis(2, 1:dim(d)[2], colnames(d), las=2)

las=0 would flip the names back to their normal position, mine were long, so I used las=2 to make them perpendicular to the axis.

edit2: to suppress the image() function printing numbers on the grid (otherwise they overlap your variable labels), add xaxt='n', e.g.:

image(x=seq(dim(x)[2]), y=seq(dim(y)[2]), z=COR, col=rev(heat.colors(20)), xlab="x column", ylab="y column", xaxt='n')

A much simpler approach I found is to use plt.imsave :

    import matplotlib.pyplot as plt
    arr = plt.imread(path)
    plt.imsave('test.png', arr)

Provided you aren't using the same destination view controller with different identifiers, the code can be more concise than the other solutions (and avoids the as! in some of the other answers):

override func prepare(for segue: NSStoryboardSegue, sender: Any?) {
    if let myViewController = segue.destinationController as? MyViewController { 
        // Set up the VC
    }
}

#include <windows.h>

double PCFreq = 0.0;
__int64 CounterStart = 0;

void StartCounter()
{
    LARGE_INTEGER li;
    if(!QueryPerformanceFrequency(&li))
    cout << "QueryPerformanceFrequency failed!\n";

    PCFreq = double(li.QuadPart)/1000.0;

    QueryPerformanceCounter(&li);
    CounterStart = li.QuadPart;
}
double GetCounter()
{
    LARGE_INTEGER li;
    QueryPerformanceCounter(&li);
    return double(li.QuadPart-CounterStart)/PCFreq;
}

int main()
{
    StartCounter();
    Sleep(1000);
    cout << GetCounter() <<"\n";
    return 0;
}

This program should output a number close to 1000 (windows sleep isn't that accurate, but it should be like 999).

The StartCounter() function records the number of ticks the performance counter has in the CounterStart variable. The GetCounter() function returns the number of milliseconds since StartCounter() was last called as a double, so if GetCounter() returns 0.001 then it has been about 1 microsecond since StartCounter() was called.

If you want to have the timer use seconds instead then change

PCFreq = double(li.QuadPart)/1000.0;

to

PCFreq = double(li.QuadPart);

or if you want microseconds then use

PCFreq = double(li.QuadPart)/1000000.0;

But really it's about convenience since it returns a double.

Yes!

Here you have another example:

UPDATE prices
SET final_price= CASE
   WHEN currency=1 THEN 0.81*final_price
   ELSE final_price
END

This works because MySQL doesn't update the row, if there is no change, as mentioned in docs:

If you set a column to the value it currently has, MySQL notices this and does not update it.

I know that it's an old question, but you can change the Response using a parameter (P):

public class Response<P> implements Serializable{

private static final long serialVersionUID = 1L;

public enum MessageCode {
    SUCCESS, ERROR, UNKNOWN
}

private MessageCode code;
private String message;
private P payload;

...
public P getPayload() {
    return payload;
}

public void setPayload(P payload) {
    this.payload = payload;
}

}

The method would be

public Response<Departments> getDepartments(){...}

I can't try it now but it should works.

Otherwise it's possible to extends Response

@XmlRootElement    
public class DepResponse extends Response<Department> {<no content>}

1. You can use the FindIndex() method to find the index of item.
2. Create a new list item.
3. Override indexed item with the new item.

List<Class1> list = new List<Class1>();

int index = list.FindIndex(item => item.Number == textBox6.Text);

Class1 newItem = new Class1();
newItem.Prob1 = "SomeValue";

list[index] = newItem;

If owner names differ, sort by them. Otherwise, use publication name for tiebreaker.

function mysortfunction(a, b) {

  var o1 = a[3].toLowerCase();
  var o2 = b[3].toLowerCase();

  var p1 = a[1].toLowerCase();
  var p2 = b[1].toLowerCase();

  if (o1 < o2) return -1;
  if (o1 > o2) return 1;
  if (p1 < p2) return -1;
  if (p1 > p2) return 1;
  return 0;
}

Maybe a library (DLL file) you are using requires another library. In my case, I referenced a library that contained a database entity model - but I forgot to reference the entity framework library.

As defined in App_start.BundleConfig, it's just calling

bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/site.css"));

Nothing happens even if you remove that section.

Yes You Can!

I worked on a project that did that (see comment). Unfortunately no code samples from that one, but googling revealed these:

How you can integrate data from several Web services using Excel and VBA

STEP BY STEP: Consuming Web Services through VBA (Excel or Word)

Don't type python test.py from inside the Python interpreter. Type it at the command prompt, like so:

I had a similar problem.

As it turned out, I ran mvn clean package install.

Correct way is mvn clean install

If you need the subdirectories too you need a "dir" command and a "For" command

dir /b /s DIRECTORY\*.* > list1.txt

for /f "tokens=*" %%A in (list1.txt) do echo %%~nxA >> list.txt

del list1.txt

put your root directory in dir command. It will create a list1.txt with full path names and then a list.txt with only the file names.

Try using the non-breaking hyphen ‑. I've replaced the dash with that character in your jsfiddle, shrunk the frame down as small as it can go, and the line doesn't split there any more.

Additionally Remember, Don't forget to add public keyword like this

[Key] 
int RoleId { get; set; } //wrong method

you must use Public keyword like this

[Key] 
public int RoleId { get; set; } //correct method

we can use the below to get key as string from JSON OBJECT

JsonObject json = new JsonObject(); 
 json.get("key").getAsString();

this gives the string without double quotes " " in the string

You can disable animation, transition, trasforms for all of element in page with this css code

var style = document.createElement('style');
style.type = 'text/css';
style.innerHTML = '* {' +
'/*CSS transitions*/' +
' -o-transition-property: none !important;' +
' -moz-transition-property: none !important;' +
' -ms-transition-property: none !important;' +
' -webkit-transition-property: none !important;' +
'  transition-property: none !important;' +
'/*CSS transforms*/' +
'  -o-transform: none !important;' +
' -moz-transform: none !important;' +
'   -ms-transform: none !important;' +
'  -webkit-transform: none !important;' +
'   transform: none !important;' +
'  /*CSS animations*/' +
'   -webkit-animation: none !important;' +
'   -moz-animation: none !important;' +
'   -o-animation: none !important;' +
'   -ms-animation: none !important;' +
'   animation: none !important;}';
   document.getElementsByTagName('head')[0].appendChild(style);

Try to use https://www.pagedjs.org/. It polyfills page counter, header-/footer-functionality for all major browsers.

@page {
  @bottom-left {
    content: counter(page) ' of ' counter(pages);
  }
}

It's so much more comfortable compared to alternatives like PrinceXML, Antennahouse, WeasyPrince, PDFReactor, etc ...

And it is totally free! No pricing or whatever. It really saved my life!

You can use down-stepping to achieve better results. Most browsers seem to use linear interpolation rather than bi-cubic when resizing images.

(Update There has been added a quality property to the specs, imageSmoothingQuality which is currently available in Chrome only.)

Unless one chooses no smoothing or nearest neighbor the browser will always interpolate the image after down-scaling it as this function as a low-pass filter to avoid aliasing.

Bi-linear uses 2x2 pixels to do the interpolation while bi-cubic uses 4x4 so by doing it in steps you can get close to bi-cubic result while using bi-linear interpolation as seen in the resulting images.

var canvas = document.getElementById("canvas");_x000D_
var ctx = canvas.getContext("2d");_x000D_
var img = new Image();_x000D_
_x000D_
img.onload = function () {_x000D_
_x000D_
    // set size proportional to image_x000D_
    canvas.height = canvas.width * (img.height / img.width);_x000D_
_x000D_
    // step 1 - resize to 50%_x000D_
    var oc = document.createElement('canvas'),_x000D_
        octx = oc.getContext('2d');_x000D_
_x000D_
    oc.width = img.width * 0.5;_x000D_
    oc.height = img.height * 0.5;_x000D_
    octx.drawImage(img, 0, 0, oc.width, oc.height);_x000D_
_x000D_
    // step 2_x000D_
    octx.drawImage(oc, 0, 0, oc.width * 0.5, oc.height * 0.5);_x000D_
_x000D_
    // step 3, resize to final size_x000D_
    ctx.drawImage(oc, 0, 0, oc.width * 0.5, oc.height * 0.5,_x000D_
    0, 0, canvas.width, canvas.height);_x000D_
}_x000D_
img.src = "//i.imgur.com/SHo6Fub.jpg";

<img src="//i.imgur.com/SHo6Fub.jpg" width="300" height="234">_x000D_
<canvas id="canvas" width=300></canvas>

Depending on how drastic your resize is you can might skip step 2 if the difference is less.

In the demo you can see the new result is now much similar to the image element.

I'm sorry, I still yet cant comment, so to answer Tom's answer... In javascript (undefined != null) == false In fact that function wont work with "null", you should use "undefined"

To set custom headers ON A REQUEST, build a request with the custom header before passing it to httpclient to send to http server. eg:

HttpClient client = HttpClients.custom().build();
HttpUriRequest request = RequestBuilder.get()
  .setUri(someURL)
  .setHeader(HttpHeaders.CONTENT_TYPE, "application/json")
  .build();
client.execute(request);

Default header is SET ON HTTPCLIENT to send on every request to the server.

The problem is using with statement:

with open('strings.json') as json_data:
    d = json.load(json_data)
    pprint(d)

The file is going to be implicitly closed already. There is no need to call json_data.close() again.

I needed a common event handler in which I can show from which button it is called without using switch case... and done like this..

  Private Sub btn_done_clicked(ByVal sender As System.Object, ByVal e As System.EventArgs)

    MsgBox.Show("you have clicked button " & CType(CType(sender,  _
    System.Windows.Forms.Button).Tag, String))

  End Sub

I see lots of confusion in the comments. Null, IsNull() and vbNull are mainly used for database handling and normally not used in VBScript. If it is not explicitly stated in the documentation of the calling object/data, do not use it.

To test if a variable is uninitialized, use IsEmpty(). To test if a variable is uninitialized or contains "", test on "" or Empty. To test if a variable is an object, use IsObject and to see if this object has no reference test on Is Nothing.

In your case, you first want to test if the variable is an object, and then see if that variable is Nothing, because if it isn't an object, you get the "Object Required" error when you test on Nothing.

snippet to mix and match in your code:

If IsObject(provider) Then
    If Not provider Is Nothing Then
        ' Code to handle a NOT empty object / valid reference
    Else
        ' Code to handle an empty object / null reference
    End If
Else
    If IsEmpty(provider) Then
        ' Code to handle a not initialized variable or a variable explicitly set to empty
    ElseIf provider = "" Then
        ' Code to handle an empty variable (but initialized and set to "")
    Else
        ' Code to handle handle a filled variable
    End If
End If

I initially used IsNothing but I've been moving towards using Is Nothing in newer projects, mainly for readability. The only time I stick with IsNothing is if I'm maintaining code where that's used throughout and I want to stay consistent.

I was just wondering how the random number generator in C# works.

That's implementation-specific, but the wikipedia entry for pseudo-random number generators should give you some ideas.

I was also curious how I could make a program that generates random WHOLE INTEGER numbers from 1-100.

You can use Random.Next(int, int):

Random rng = new Random();
for (int i = 0; i < 10; i++)
{
    Console.WriteLine(rng.Next(1, 101));
}

Note that the upper bound is exclusive - which is why I've used 101 here.

You should also be aware of some of the "gotchas" associated with Random - in particular, you should not create a new instance every time you want to generate a random number, as otherwise if you generate lots of random numbers in a short space of time, you'll see a lot of repeats. See my article on this topic for more details.

Yet another option is to have, in Ticket, one column specifying the owning entity type (User or Group), second column with referenced User or Group id and NOT to use Foreign Keys but instead rely on a Trigger to enforce referential integrity.

Two advantages I see here over Nathan's excellent model (above):

• More immediate clarity and simplicity.
• Simpler queries to write.

I know this is an old post and you marked the question as answered. I was looking for the same thing recently and I found the histedit extension very useful. The process is explained here:

http://knowledgestockpile.blogspot.com/2010/12/changing-commit-message-of-revision-in.html

There is one more ability to achieve a desired results: command trap. It can be used to clean-up purposes for example.

As noted in the comments, this only works AFTER you've DataBound your repeater.

To find a control in the header:

lblControl = repeater1.Controls[0].Controls[0].FindControl("lblControl");

To find a control in the footer:

lblControl = repeater1.Controls[repeater1.Controls.Count - 1].Controls[0].FindControl("lblControl");

With extension methods

public static class RepeaterExtensionMethods
{
    public static Control FindControlInHeader(this Repeater repeater, string controlName)
    {
        return repeater.Controls[0].Controls[0].FindControl(controlName);
    }

    public static Control FindControlInFooter(this Repeater repeater, string controlName)
    {
        return repeater.Controls[repeater.Controls.Count - 1].Controls[0].FindControl(controlName);
    }
}

Use '-R' to backup stored procedures, but also keep in mind that if you want a consistent dump of your database while its being modified you need to use --single-transaction (if you only backup innodb) or --lock-all-tables (if you also need myisam tables)

First, Update your last perfect migration via this command :

Update-Database –TargetMigration

Example:

Update-Database -20180906131107_xxxx_xxxx

And, then delete your unused migration manually.

In Python 3.8+ you can do

import hashlib
with open("your_filename.txt", "rb") as f:
    file_hash = hashlib.md5()
    while chunk := f.read(8192):
        file_hash.update(chunk)

print(file_hash.digest())
print(file_hash.hexdigest())  # to get a printable str instead of bytes

Consider using hashlib.blake2b instead of md5 (just replace md5 with blake2b in the above snippet). It's cryptographically secure and faster than MD5.

You need to use a while loop. If you make a while loop, and there's no instruction after the loop, it'll become an infinite loop,and won't stop until you manually stop it.

While using the --prefix option works, you have to explicitly use it every time you create an environment. If you just want your environments stored somewhere else by default, you can configure it in your .condarc file.

Please see: https://conda.io/docs/user-guide/configuration/use-condarc.html#specify-environment-directories-envs-dirs

In Xcode 8 beta 4 does not work...

Use:

DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
    print("Are we there yet?")
}

for async two ways:

DispatchQueue.main.async {
    print("Async1")
}

DispatchQueue.main.async( execute: {
    print("Async2")
})

If you are doing complex, async input validation it might be worth it to abstract ng-model up one level as part of a custom class with its own validation methods.

To add multiples params or headers you can do the following:

constructor(private _http: HttpClient) {}

//....

const url = `${environment.APP_API}/api/request`;

let headers = new HttpHeaders().set('header1', hvalue1); // create header object
headers = headers.append('header2', hvalue2); // add a new header, creating a new object
headers = headers.append('header3', hvalue3); // add another header

let params = new HttpParams().set('param1', value1); // create params object
params = params.append('param2', value2); // add a new param, creating a new object
params = params.append('param3', value3); // add another param 

return this._http.get<any[]>(url, { headers: headers, params: params })

• Does not matter for inner joins

• Matters for outer joins

  a. WHERE clause: After joining. Records will be filtered after join has taken place.

  b. ON clause - Before joining. Records (from right table) will be filtered before joining. This may end up as null in the result (since OUTER join).

Example: Consider the below tables:

    1. documents:
     | id    | name        |
     --------|-------------|
     | 1     | Document1   |
     | 2     | Document2   |
     | 3     | Document3   |
     | 4     | Document4   |
     | 5     | Document5   |


    2. downloads:
     | id   | document_id   | username |
     |------|---------------|----------|
     | 1    | 1             | sandeep  |
     | 2    | 1             | simi     |
     | 3    | 2             | sandeep  |
     | 4    | 2             | reya     |
     | 5    | 3             | simi     |

a) Inside WHERE clause:

  SELECT documents.name, downloads.id
    FROM documents
    LEFT OUTER JOIN downloads
      ON documents.id = downloads.document_id
    WHERE username = 'sandeep'

 For above query the intermediate join table will look like this.

    | id(from documents) | name         | id (from downloads) | document_id | username |
    |--------------------|--------------|---------------------|-------------|----------|
    | 1                  | Document1    | 1                   | 1           | sandeep  |
    | 1                  | Document1    | 2                   | 1           | simi     |
    | 2                  | Document2    | 3                   | 2           | sandeep  |
    | 2                  | Document2    | 4                   | 2           | reya     |
    | 3                  | Document3    | 5                   | 3           | simi     |
    | 4                  | Document4    | NULL                | NULL        | NULL     |
    | 5                  | Document5    | NULL                | NULL        | NULL     |

  After applying the `WHERE` clause and selecting the listed attributes, the result will be: 

   | name         | id |
   |--------------|----|
   | Document1    | 1  |
   | Document2    | 3  | 

b) Inside JOIN clause

  SELECT documents.name, downloads.id
  FROM documents
    LEFT OUTER JOIN downloads
      ON documents.id = downloads.document_id
        AND username = 'sandeep'

For above query the intermediate join table will look like this.

    | id(from documents) | name         | id (from downloads) | document_id | username |
    |--------------------|--------------|---------------------|-------------|----------|
    | 1                  | Document1    | 1                   | 1           | sandeep  |
    | 2                  | Document2    | 3                   | 2           | sandeep  |
    | 3                  | Document3    | NULL                | NULL        | NULL     |
    | 4                  | Document4    | NULL                | NULL        | NULL     |
    | 5                  | Document5    | NULL                | NULL        | NULL     |

Notice how the rows in `documents` that did not match both the conditions are populated with `NULL` values.

After Selecting the listed attributes, the result will be: 

   | name       | id   |
   |------------|------|
   |  Document1 | 1    |
   |  Document2 | 3    | 
   |  Document3 | NULL |
   |  Document4 | NULL | 
   |  Document5 | NULL | 

For people with only one IP address and multiple sites on one server, you can configure IIS to listen on a port other than 80, e.g 8080 by setting the TCP port in the properties of each of its sites (including the default one).

In Apache, enable mod_proxy and mod_proxy_http, then add a catch-all VirtualHost (after all others) so that requests Apache isn't explicitly handling get "forwarded" on to IIS.

<VirtualHost *:80>
    ServerName foo.bar
    ServerAlias *
    ProxyPreserveHost On
    ProxyPass / http://127.0.0.1:8080/
</VirtualHost>

Now you can have Apache serve some sites and IIS serve others, with no visible difference to the user.

Edit: your IIS sites must not include their port number in any URLs within their responses, including headers.

Add to your CSS:

body { 
    padding-top: 65px; 
}

From the Bootstrap docs:

The fixed navbar will overlay your other content, unless you add padding to the top of the body.

Ask this questions yourself? And you will decide your DB selection.

1. Do you need master-master? Then CouchDB. Mainly CouchDB supports master-master replication which anticipates nodes being disconnected for long periods of time. MongoDB would not do well in that environment.
2. Do you need MAXIMUM R/W throughput? Then MongoDB
3. Do you need ultimate single-server durability because you are only going to have a single DB server? Then CouchDB.
4. Are you storing a MASSIVE data set that needs sharding while maintaining insane throughput? Then MongoDB.
5. Do you need strong consistency of data? Then MongoDB.
6. Do you need high availability of database? Then CouchDB.
7. Are you hoping multi databases and multi tables/ collections? Then MongoDB
8. You have a mobile app offline users and want to sync their activity data to a server? Then you need CouchDB.
9. Do you need large variety of querying engine? Then MongoDB
10. Do you need large community to be using DB? Then MongoDB

Just for the record:

>>> int('55063.000000')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '55063.000000'

Got me here...

>>> int(float('55063.000000'))
55063.0

Has to be used!

Here is what I use.

Write-Host -NoNewLine 'Press any key to continue...';
$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown');

Recently, I faced similar problem and I solved it using following approach

def round(value: Either[Double, Float], places: Int) = {
  if (places < 0) 0
  else {
    val factor = Math.pow(10, places)
    value match {
      case Left(d) => (Math.round(d * factor) / factor)
      case Right(f) => (Math.round(f * factor) / factor)
    }
  }
}

def round(value: Double): Double = round(Left(value), 0)
def round(value: Double, places: Int): Double = round(Left(value), places)
def round(value: Float): Double = round(Right(value), 0)
def round(value: Float, places: Int): Double = round(Right(value), places)

I used this SO issue. I have couple of overloaded functions for both Float\Double and implicit\explicit options. Note that, you need to explicitly mention the return type in case of overloaded functions.

For python 2

import urllib
some_url = 'https://docs.python.org/2/library/urllib.html'
filehandle = urllib.urlopen(some_url)
print filehandle.read()

Ensure that you always check for the file extension in server-side to ensure that no one can upload a malicious file such as .aspx, .asp etc.

Use dev.new(). (See this related question.)

plot(1:10)
dev.new(width=5, height=4)
plot(1:20)

To be more specific which units are used:

dev.new(width=5, height=4, unit="in")
plot(1:20)
dev.new(width = 550, height = 330, unit = "px")
plot(1:15)

edit additional argument for Rstudio (May 2020), (thanks user Soren Havelund Welling)

For Rstudio, add dev.new(width=5,height=4,noRStudioGD = TRUE)

You could try Firebug Lite

It's a pure JavaScript-implementation of Firebug that runs directly in any browser (at least in all major ones: IE6+, Firefox, Opera, Safari and Chrome)

You'll still need the VM to actually run IE, but at least you'll get a quicker testing cycle.

You can throw your own custom errors by extending the Exception class.

class CustomException : Exception {
    [string] $additionalData

    CustomException($Message, $additionalData) : base($Message) {
        $this.additionalData = $additionalData
    }
}

try {
    throw [CustomException]::new('Error message', 'Extra data')
} catch [CustomException] {
    # NOTE: To access your custom exception you must use $_.Exception
    Write-Output $_.Exception.additionalData

    # This will produce the error message: Didn't catch it the second time
    throw [CustomException]::new("Didn't catch it the second time", 'Extra data')
}

<ul id="category-tabs">
    <li><a href="javascript:void"><i class="fa fa-plus-circle"></i>Category 1</a>
        <ul>
            <li><a href="javascript:void">item 1</a></li>
            <li><a href="javascript:void">item 2</a></li>
            <li><a href="javascript:void">item 3</a></li>
        </ul>
    </li> </ul>

//Jquery

$(document).ready(function() {
    $('li').click(function() {
      $('i').toggleClass('fa-plus-square fa-minus-square');
    });
  }); 

JSFiddle

You can use an array literal:

array = [ '1', '2', '3' ]

You can also use a range:

array = ('1'..'3').to_a  # parentheses are required
# or
array = *('1'..'3')      # parentheses not required, but included for clarity

For arrays of whitespace-delimited strings, you can use Percent String syntax:

array = %w[ 1 2 3 ]

You can also pass a block to Array.new to determine what the value for each entry will be:

array = Array.new(3) { |i| (i+1).to_s }

Finally, although it doesn't produce the same array of three strings as the other answers above, note also that you can use enumerators in Ruby 1.8.7+ to create arrays; for example:

array = 1.step(17,3).to_a
#=> [1, 4, 7, 10, 13, 16]

It is always encouraged in C++ that you have one class per header file, see this discussion in SO [1]. GManNickG answer's tells why this happen. But the best way to solve this is to put User class in one header file (User.h) and MyMessageBox class in another header file (MyMessageBox.h). Then in your User.h you include MyMessageBox.h and in MyMessageBox.h you include User.h. Do not forget "include gaurds" [2] so that your code compiles successfully.

There are a couple of ways to solve this. The least hackiest and almost what you want:

$client = new SoapClient(
    null,
    array(
        'location' => 'https://example.com/ExampleWebServiceDL/services/ExampleHandler',
        'uri' => 'http://example.com/wsdl',
        'trace' => 1,
        'use' => SOAP_LITERAL,
    )
);
$params = new \SoapVar("<Acquirer><Id>MyId</Id><UserId>MyUserId</UserId><Password>MyPassword</Password></Acquirer>", XSD_ANYXML);
$result = $client->Echo($params);

This gets you the following XML:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://example.com/wsdl">
    <SOAP-ENV:Body>
        <ns1:Echo>
            <Acquirer>
                <Id>MyId</Id>
                <UserId>MyUserId</UserId>
                <Password>MyPassword</Password>
            </Acquirer>
        </ns1:Echo>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

That is almost exactly what you want, except for the namespace on the method name. I don't know if this is a problem. If so, you can hack it even further. You could put the <Echo> tag in the XML string by hand and have the SoapClient not set the method by adding 'style' => SOAP_DOCUMENT, to the options array like this:

$client = new SoapClient(
    null,
    array(
        'location' => 'https://example.com/ExampleWebServiceDL/services/ExampleHandler',
        'uri' => 'http://example.com/wsdl',
        'trace' => 1,
        'use' => SOAP_LITERAL,
        'style' => SOAP_DOCUMENT,
    )
);
$params = new \SoapVar("<Echo><Acquirer><Id>MyId</Id><UserId>MyUserId</UserId><Password>MyPassword</Password></Acquirer></Echo>", XSD_ANYXML);
$result = $client->MethodNameIsIgnored($params);

This results in the following request XML:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body>
        <Echo>
            <Acquirer>
                <Id>MyId</Id>
                <UserId>MyUserId</UserId>
                <Password>MyPassword</Password>
            </Acquirer>
        </Echo>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Finally, if you want to play around with SoapVar and SoapParam objects, you can find a good reference in this comment in the PHP manual: http://www.php.net/manual/en/soapvar.soapvar.php#104065. If you get that to work, please let me know, I failed miserably.

Hi for example if you have split and replace in String 07:05:45PM

var hour = time.replace("PM", "").split(":");

Result

[ '07', '05', '45' ]

This should get you for starting with two letters and ending with two numbers.

[A-Za-z]{2}(.*)[0-9]{2}

If you know it will always be just two and two you can

[A-Za-z]{2}[0-9]{2}

In real life you wish to simulate a signal with white noise. You should add to your signal random points that have Normal Gaussian distribution. If we speak about a device that have sensitivity given in unit/SQRT(Hz) then you need to devise standard deviation of your points from it. Here I give function "white_noise" that does this for you, an the rest of a code is demonstration and check if it does what it should.

%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
from scipy import signal

"""
parameters: 
rhp - spectral noise density unit/SQRT(Hz)
sr  - sample rate
n   - no of points
mu  - mean value, optional

returns:
n points of noise signal with spectral noise density of rho
"""
def white_noise(rho, sr, n, mu=0):
    sigma = rho * np.sqrt(sr/2)
    noise = np.random.normal(mu, sigma, n)
    return noise

rho = 1 
sr = 1000
n = 1000
period = n/sr
time = np.linspace(0, period, n)
signal_pure = 100*np.sin(2*np.pi*13*time)
noise = white_noise(rho, sr, n)
signal_with_noise = signal_pure + noise

f, psd = signal.periodogram(signal_with_noise, sr)

print("Mean spectral noise density = ",np.sqrt(np.mean(psd[50:])), "arb.u/SQRT(Hz)")

plt.plot(time, signal_with_noise)
plt.plot(time, signal_pure)
plt.xlabel("time (s)")
plt.ylabel("signal (arb.u.)")
plt.show()

plt.semilogy(f[1:], np.sqrt(psd[1:]))
plt.xlabel("frequency (Hz)")
plt.ylabel("psd (arb.u./SQRT(Hz))")
#plt.axvline(13, ls="dashed", color="g")
plt.axhline(rho, ls="dashed", color="r")
plt.show()

Turing Complete means that it is at least as powerful as a Turing Machine. This means anything that can be computed by a Turing Machine can be computed by a Turing Complete system.

No one has yet found a system more powerful than a Turing Machine. So, for the time being, saying a system is Turing Complete is the same as saying the system is as powerful as any known computing system (see Church-Turing Thesis).

UPDATE (GEOCODE MULTIPLE ADDRESSES)

Here's the working Example Geocoding with multiple addresses.

 <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false">
 </script> 
 <script type="text/javascript">
  var delay = 100;
  var infowindow = new google.maps.InfoWindow();
  var latlng = new google.maps.LatLng(21.0000, 78.0000);
  var mapOptions = {
    zoom: 5,
    center: latlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  }
  var geocoder = new google.maps.Geocoder(); 
  var map = new google.maps.Map(document.getElementById("map"), mapOptions);
  var bounds = new google.maps.LatLngBounds();

  function geocodeAddress(address, next) {
    geocoder.geocode({address:address}, function (results,status)
      { 
         if (status == google.maps.GeocoderStatus.OK) {
          var p = results[0].geometry.location;
          var lat=p.lat();
          var lng=p.lng();
          createMarker(address,lat,lng);
        }
        else {
           if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
            nextAddress--;
            delay++;
          } else {
                        }   
        }
        next();
      }
    );
  }
 function createMarker(add,lat,lng) {
   var contentString = add;
   var marker = new google.maps.Marker({
     position: new google.maps.LatLng(lat,lng),
     map: map,
           });

  google.maps.event.addListener(marker, 'click', function() {
     infowindow.setContent(contentString); 
     infowindow.open(map,marker);
   });

   bounds.extend(marker.position);

 }
  var locations = [
           'New Delhi, India',
           'Mumbai, India',
           'Bangaluru, Karnataka, India',
           'Hyderabad, Ahemdabad, India',
           'Gurgaon, Haryana, India',
           'Cannaught Place, New Delhi, India',
           'Bandra, Mumbai, India',
           'Nainital, Uttranchal, India',
           'Guwahati, India',
           'West Bengal, India',
           'Jammu, India',
           'Kanyakumari, India',
           'Kerala, India',
           'Himachal Pradesh, India',
           'Shillong, India',
           'Chandigarh, India',
           'Dwarka, New Delhi, India',
           'Pune, India',
           'Indore, India',
           'Orissa, India',
           'Shimla, India',
           'Gujarat, India'
  ];
  var nextAddress = 0;
  function theNext() {
    if (nextAddress < locations.length) {
      setTimeout('geocodeAddress("'+locations[nextAddress]+'",theNext)', delay);
      nextAddress++;
    } else {
      map.fitBounds(bounds);
    }
  }
  theNext();

</script>

As we can resolve this issue with setTimeout() function.

Still we should not geocode known locations every time you load your page as said by @geocodezip

Another alternatives of these are explained very well in the following links:

How To Avoid GoogleMap Geocode Limit!

Geocode Multiple Addresses Tutorial By Mike Williams

Example by Google Developers

function valid(id)
    {
        var textVal=document.getElementById(id).value;
        if (!textVal.match("Tryit") 
        {
            alert("Field says Tryit");
            return false;
        } 
        else 
        {
            return true;
        }
     }

Use this for expressing things

Python has a built in method on strings called replace which is used as so:

string.replace(old, new)

So you would use:

string.replace(" ", "_")

I had this problem a while ago and I wrote code to replace characters in a string. I have to start remembering to check the python documentation because they've got built in functions for everything.

.scroll {
   width: 200px; height: 400px;
   overflow: auto;
}

Depends ay which point you wish to "catch" the value.

For instance, if you want to catch the value as soon as the user changes the spinner selected item, use the listener approach (provided by jalopaba)

If you rather catch the value when a user performs the final task like clicking a Submit button, or something, then the answer provided by Rich is better.

For me the UnicodeWriter class from Python 2 CSV module documentation didn't really work as it breaks the csv.writer.write_row() interface.

For example:

csv_writer = csv.writer(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)

works, while:

csv_writer = UnicodeWriter(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)

will throw AttributeError: 'int' object has no attribute 'encode'.

As UnicodeWriter obviously expects all column values to be strings, we can convert the values ourselves and just use the default CSV module:

def to_utf8(lst):
    return [unicode(elem).encode('utf-8') for elem in lst]

...
csv_writer.writerow(to_utf8(row))

Or we can even monkey-patch csv_writer to add a write_utf8_row function - the exercise is left to the reader.

It would look like this:

public static final String WELCOME_MESSAGE = "Hello, welcome to the server";

If the constants are for use just in a single class, you'd want to make them private instead of public.

You need to run this command in the top-level directory of a Selenium SVN repository checkout.

Methinks the word "console" is causing the confusion.

If you want to emulate an old-style full/half duplex console, you'd use something like this:

$('console').keyup(function(event){
    $.get("url", { keyCode: event.which }, ... );
    return true;
});

event.which has the key that was pressed. For backspace handling, event.which === 8.

Another probably more generic and simpler solution is to create a dictionary keyed by the string version of the objects and getting the values() at the end:

>>> dict([(unicode(a),a) for a in [["A", "A"], ["A", "A"], ["A", "B"]]]).values()
[['A', 'B'], ['A', 'A']]

The catch is that this only works for objects whose string representation is a good-enough unique key (which is true for most native objects).

You can simply get it in the format you want.

String date = String.valueOf(android.text.format.DateFormat.format("dd-MM-yyyy", new java.util.Date()));

For example if there are 4 project and a root project, add the other child projects to build path of root project. If there is not selection of build path, add below codes to .project file.

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>

Create a text node and append it to the button element:

var t = document.createTextNode("test content");
b.appendChild(t);

I think the performance will be quite similar. The overhead that is involved when using a List vs an Array is, IMHO when you add items to the list, and when the list has to increase the size of the array that it's using internally, when the capacity of the array is reached.

Suppose you have a List with a Capacity of 10, then the List will increase it's capacity once you want to add the 11th element. You can decrease the performance impact by initializing the Capacity of the list to the number of items it will hold.

But, in order to figure out if iterating over a List is as fast as iterating over an array, why don't you benchmark it ?

int numberOfElements = 6000000;

List<int> theList = new List<int> (numberOfElements);
int[] theArray = new int[numberOfElements];

for( int i = 0; i < numberOfElements; i++ )
{
    theList.Add (i);
    theArray[i] = i;
}

Stopwatch chrono = new Stopwatch ();

chrono.Start ();

int j;

 for( int i = 0; i < numberOfElements; i++ )
 {
     j = theList[i];
 }

 chrono.Stop ();
 Console.WriteLine (String.Format("iterating the List took {0} msec", chrono.ElapsedMilliseconds));

 chrono.Reset();

 chrono.Start();

 for( int i = 0; i < numberOfElements; i++ )
 {
     j = theArray[i];
 }

 chrono.Stop ();
 Console.WriteLine (String.Format("iterating the array took {0} msec", chrono.ElapsedMilliseconds));

 Console.ReadLine();

On my system; iterating over the array took 33msec; iterating over the list took 66msec.

To be honest, I didn't expect that the variation would be that much. So, I've put my iteration in a loop: now, I execute both iteration 1000 times. The results are:

iterating the List took 67146 msec iterating the array took 40821 msec

Now, the variation is not that large anymore, but still ...

Therefore, I've started up .NET Reflector, and the getter of the indexer of the List class, looks like this:

public T get_Item(int index)
{
    if (index >= this._size)
    {
        ThrowHelper.ThrowArgumentOutOfRangeException();
    }
    return this._items[index];
}

As you can see, when you use the indexer of the List, the List performs a check whether you're not going out of the bounds of the internal array. This additional check comes with a cost.

If it is just one instance that needs to be wrapped over 2 or 3 lines I would just use a few <wbr> in the string. It will treat those just like <br> but it wont insert the line break if it isn't necessary.

<div id="w74" class="dpinfo">
adsfadsadsads<wbr>fadsadsadsfadsadsa<wbr>dsfadsadsadsfadsadsads<wbr>fadsadsadsfadsadsadsfa<wbr>dsadsadsfadsadsadsfadsad<wbr>sadsfadsadsads<wbr>fadsadsadsfadsads adsfadsads
</div>

Here is a fiddle.

When we create new types by defining classes, we can take advantage of certain features of Python to make the new classes convenient to use. One of these features is "special methods", also referred to as "magic methods".

Special methods have names that begin and end with two underscores. We define them, but do not usually call them directly by name. Instead, they execute automatically under under specific circumstances.

It is convenient to be able to output the value of an instance of an object by using a print statement. When we do this, we would like the value to be represented in the output in some understandable unambiguous format. The repr special method can be used to arrange for this to happen. If we define this method, it can get called automatically when we print the value of an instance of a class for which we defined this method. It should be mentioned, though, that there is also a str special method, used for a similar, but not identical purpose, that may get precedence, if we have also defined it.

If we have not defined, the repr method for the Point3D class, and have instantiated my_point as an instance of Point3D, and then we do this ...

print my_point ... we may see this as the output ...

Not very nice, eh?

So, we define the repr or str special method, or both, to get better output.

**class Point3D(object):
    def __init__(self,a,b,c):
        self.x = a
        self.y = b
        self.z = c
    def __repr__(self):
        return "Point3D(%d, %d, %d)" % (self.x, self.y, self.z)
    def __str__(self):
        return "(%d, %d, %d)" % (self.x, self.y, self.z)
my_point = Point3D(1, 2, 3)
print my_point # __repr__ gets called automatically
print my_point # __str__ gets called automatically**

Output ...

(1, 2, 3) (1, 2, 3)

I think that CodeRush has a free, limited version, too. I ended up going with ReSharper, and I still recommend it, even though some of the functionality is in Visual Studio 2010. There are just some things that make it worth it.

Keep in mind that you don't need the full ReSharper license if you only code in one language. I have the C# version, and it's cheaper.

Simple way to differentiate UTF-8 and UTF-16 is to identify commonalities between them.

Other than sharing same unicode number for given character, each one is their own format.

UTF-8 try to represent, every unicode number given to character with one byte(If it is ASCII), else 2 two bytes, else 4 bytes and so on...

UTF-16 try to represent, every unicode number given to character with two byte to start with. If two bytes are not sufficient, then uses 4 bytes. IF that is also not sufficient, then uses 6 bytes.

Theoretically, UTF-16 is more space efficient, but in practical UTF-8 is more space efficient as most of the characters(98% of data) for processing are ASCII and UTF-8 try to represent them with single byte and UTF-16 try to represent them with 2 bytes.

Also, UTF-8 is superset of ASCII encoding. So every app that expects ASCII data would also accepted by UTF-8 processor. This is not true for UTF-16. UTF-16 could not understand ASCII, and this is big hurdle for UTF-16 adoption.

Another point to note is, all UNICODE as of now could be fit in 4 bytes of UTF-8 maximum(Considering all languages of world). This is same as UTF-16 and no real saving in space compared to UTF-8 ( https://stackoverflow.com/a/8505038/3343801 )

So, people use UTF-8 where ever possible.

You must add your keyListener to every component that you need. Only the component with the focus will send these events. For instance, if you have only one TextBox in your JFrame, that TextBox has the focus. So you must add a KeyListener to this component as well.

The process is the same:

myComponent.addKeyListener(new KeyListener ...);

Note: Some components aren't focusable like JLabel.

For setting them to focusable you need to:

myComponent.setFocusable(true);

Yes, template member functions are perfectly legal and useful on numerous occasions.

The only caveat is that template member functions cannot be virtual.

To solve Google security, do this:

Lines to the top:

import android.webkit.SslErrorHandler;
import android.net.http.SslError;

Code:

class SSLTolerentWebViewClient extends WebViewClient {
    @Override
    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
        if (error.toString() == "piglet")
            handler.cancel();
        else
            handler.proceed(); // Ignore SSL certificate errors
    }
}

This approach works for me in Node.js, Is there any problem with this one?

File 'include.js':

fs = require('fs');

File 'main.js':

require('./include.js');

fs.readFile('./file.json', function (err, data) {
    if (err) {
        console.log('ERROR: file.json not found...')
    } else {
        contents = JSON.parse(data)
    };
})

Use count(*)

declare 
   cnt integer;
begin
  SELECT count(*) INTO cnt
  FROM people
  WHERE person_id = my_person_id;

IF cnt > 0 THEN
  -- Do something
END IF;

Edit (for the downvoter who didn't read the statement and others who might be doing something similar)

The solution is only effective because there is a where clause on a column (and the name of the column suggests that its the primary key - so the where clause is highly effective)

Because of that where clause there is no need to use a LIMIT or something else to test the presence of a row that is identified by its primary key. It is an effective way to test this.

Well here is a nice script to TRIM all varchar columns on a table dynamically:

--Just change table name
declare @MyTable varchar(100)
set @MyTable = 'MyTable'

--temp table to get column names and a row id
select column_name, ROW_NUMBER() OVER(ORDER BY column_name) as id into #tempcols from INFORMATION_SCHEMA.COLUMNS 
WHERE   DATA_TYPE IN ('varchar', 'nvarchar') and TABLE_NAME = @MyTable

declare @tri int
select @tri = count(*) from #tempcols
declare @i int
select @i = 0
declare @trimmer nvarchar(max)
declare @comma varchar(1)
set @comma = ', '

--Build Update query
select @trimmer = 'UPDATE [dbo].[' + @MyTable + '] SET '

WHILE @i <= @tri 
BEGIN

    IF (@i = @tri)
        BEGIN
        set @comma = ''
        END
    SELECT  @trimmer = @trimmer + CHAR(10)+ '[' + COLUMN_NAME + '] = LTRIM(RTRIM([' + COLUMN_NAME + ']))'+@comma
    FROM    #tempcols
    where id = @i

    select @i = @i+1
END

--execute the entire query
EXEC sp_executesql @trimmer

drop table #tempcols

for who one in laravel 5 or greater in blade:

{{ $table->appends(['id' => $something ])->links() }}

you can get the passed item with

$passed_item=$request->id;

test it with

dd($passed_item);

you must get $something value

Using requests and json makes it simple.

1. Call the API
2. Assuming the API returns a JSON, parse the JSON object into a Python dict using json.loads function
3. Loop through the dict to extract information.

Requests module provides you useful function to loop for success and failure.

if(Response.ok): will help help you determine if your API call is successful (Response code - 200)

Response.raise_for_status() will help you fetch the http code that is returned from the API.

Below is a sample code for making such API calls. Also can be found in github. The code assumes that the API makes use of digest authentication. You can either skip this or use other appropriate authentication modules to authenticate the client invoking the API.

#Python 2.7.6
#RestfulClient.py

import requests
from requests.auth import HTTPDigestAuth
import json

# Replace with the correct URL
url = "http://api_url"

# It is a good practice not to hardcode the credentials. So ask the user to enter credentials at runtime
myResponse = requests.get(url,auth=HTTPDigestAuth(raw_input("username: "), raw_input("Password: ")), verify=True)
#print (myResponse.status_code)

# For successful API call, response code will be 200 (OK)
if(myResponse.ok):

    # Loading the response data into a dict variable
    # json.loads takes in only binary or string variables so using content to fetch binary content
    # Loads (Load String) takes a Json file and converts into python data structure (dict or list, depending on JSON)
    jData = json.loads(myResponse.content)

    print("The response contains {0} properties".format(len(jData)))
    print("\n")
    for key in jData:
        print key + " : " + jData[key]
else:
  # If response code is not ok (200), print the resulting http error code with description
    myResponse.raise_for_status()

This was just fixed with 2018-09-15 (3.25.0)

Enhancements the ALTER TABLE command:

• Add support for renaming columns within a table using ALTER TABLE table RENAME COLUMN oldname TO newname.
• Fix table rename feature so that it also updates references to the renamed table in triggers and views.

You can find the new syntax documented under ALTER TABLE

The RENAME COLUMN TO syntax changes the column-name of table table-name into new-column-name. The column name is changed both within the table definition itself and also within all indexes, triggers, and views that reference the column. If the column name change would result in a semantic ambiguity in a trigger or view, then the RENAME COLUMN fails with an error and no changes are applied.

^{Image source: https://www.sqlite.org/images/syntax/alter-table-stmt.gif}

Example:

CREATE TABLE tab AS SELECT 1 AS c;

SELECT * FROM tab;

ALTER TABLE tab RENAME COLUMN c to c_new;

SELECT * FROM tab;

Android Support

As of writing, Android's API 27 is using SQLite package version 3.19.

Based on the current version that Android is using and that this update is coming in version 3.25.0 of SQLite, I would say you have bit of a wait (approximately API 33) before support for this is added to Android.

And, even then, if you need to support any versions older than the API 33, you will not be able to use this.

HTML

<span ng-class="{'item-text-wrap':viewMore}" ng-click="viewMore= !viewMore"></span>

Since I currently have the same problem here is what I do:

1. I prefer com.sun.Reflection instead of stackTrace since a stack trace is only producing the name not the class (including the classloader) itself.

2. The method is deprecated but still around in Java 8 SDK.

// Method descriptor #124 (I)Ljava/lang/Class; (deprecated) // Signature: (I)Ljava/lang/Class<*>; @java.lang.Deprecated public static native java.lang.Class getCallerClass(int arg0);

3. The method without int argument is not deprecated

// Method descriptor #122 ()Ljava/lang/Class; // Signature: ()Ljava/lang/Class<*>; @sun.reflect.CallerSensitive public static native java.lang.Class getCallerClass();

Since I have to be platform independent bla bla including Security Restrictions, I just create a flexible method:

1. Check if com.sun.Reflection is available (security exceptions disable this mechanism)

2. If 1 is yes then get the method with int or no int argument.

3. If 2 is yes call it.

If 3. was never reached, I use the stack trace to return the name. I use a special result object that contains either the class or the string and this object tells exactly what it is and why.

[Summary] I use stacktrace for backup and to bypass eclipse compiler warnings I use reflections. Works very good. Keeps the code clean, works like a charm and also states the problems involved correctly.

I use this for quite a long time and today I searched a related question so

Map<Integer, String> map = new HashMap<>();
map.put(1, "B");
map.put(2, "C");
map.put(3, "D");
map.put(4, "A");

List<String> list = map.values()
                       .stream()
                       .sorted()
                       .collect(Collectors.toList());

Output: [A, B, C, D]

Alternatively you can also,

1) Navigate to that method by Ctrl+Click on the method. The new tab/window will opened with text "Source not found" and button "Attach Source.." in it
2) Click the button "Attach Source.."
3) New window pops up. Click the button "External Folder"
4) Locate the JavaFX javadoc folder. If you are on Windows with default installation settings, then the folder path is C:\Program Files\Oracle\JavaFX 2.0 SDK\docs

With respect to other answers, it's not always there. Sometimes on setup process people forget to select the Web Developer Tools.

In order to fix that, one should:

1. Open Programs and Features find Visual Studios related version there, click on it,
2. Click to Change. Then the setup window will appear,
3. Select Web Developer Tools there and continue to setup.

It will download or use the setup media if exist. After the setup windows may restart, and you are ready to have fun with your Web Developer Tools now.

Try a list comprehension:

l = [x * 2 for x in l]

This goes through l, multiplying each element by two.

Of course, there's more than one way to do it. If you're into lambda functions and map, you can even do

l = map(lambda x: x * 2, l)

to apply the function lambda x: x * 2 to each element in l. This is equivalent to:

def timesTwo(x):
    return x * 2

l = map(timesTwo, l)

Note that map() returns a map object, not a list, so if you really need a list afterwards you can use the list() function afterwards, for instance:

l = list(map(timesTwo, l))

Thanks to Minyc510 in the comments for this clarification.

In version r82 of Three.js TextureLoader is the object to use for loading a texture.

Loading one texture (source code, demo)

Extract (test.js):

var scene = new THREE.Scene();
var ratio = window.innerWidth / window.innerHeight;
var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight,
  0.1, 50);

var renderer = ...

[...]

/**
 * Will be called when load completes.
 * The argument will be the loaded texture.
 */
var onLoad = function (texture) {
  var objGeometry = new THREE.BoxGeometry(20, 20, 20);
  var objMaterial = new THREE.MeshPhongMaterial({
    map: texture,
    shading: THREE.FlatShading
  });

  var mesh = new THREE.Mesh(objGeometry, objMaterial);

  scene.add(mesh);

  var render = function () {
    requestAnimationFrame(render);

    mesh.rotation.x += 0.010;
    mesh.rotation.y += 0.010;

    renderer.render(scene, camera);
  };

  render();
}

// Function called when download progresses
var onProgress = function (xhr) {
  console.log((xhr.loaded / xhr.total * 100) + '% loaded');
};

// Function called when download errors
var onError = function (xhr) {
  console.log('An error happened');
};

var loader = new THREE.TextureLoader();
loader.load('texture.jpg', onLoad, onProgress, onError);

Loading multiple textures (source code, demo)

In this example the textures are loaded inside the constructor of the mesh, multiple texture are loaded using Promises.

Extract (Globe.js):

Create a new container using Object3D for having two meshes in the same container:

var Globe = function (radius, segments) {

  THREE.Object3D.call(this);

  this.name = "Globe";

  var that = this;

  // instantiate a loader
  var loader = new THREE.TextureLoader();

A map called textures where every object contains the url of a texture file and val for storing the value of a Three.js texture object.

  // earth textures
  var textures = {
    'map': {
      url: 'relief.jpg',
      val: undefined
    },
    'bumpMap': {
      url: 'elev_bump_4k.jpg',
      val: undefined
    },
    'specularMap': {
      url: 'wateretopo.png',
      val: undefined
    }
  };

The array of promises, for each object in the map called textures push a new Promise in the array texturePromises, every Promise will call loader.load. If the value of entry.val is a valid THREE.Texture object, then resolve the promise.

  var texturePromises = [], path = './';

  for (var key in textures) {
    texturePromises.push(new Promise((resolve, reject) => {
      var entry = textures[key]
      var url = path + entry.url

      loader.load(url,
        texture => {
          entry.val = texture;
          if (entry.val instanceof THREE.Texture) resolve(entry);
        },
        xhr => {
          console.log(url + ' ' + (xhr.loaded / xhr.total * 100) +
            '% loaded');
        },
        xhr => {
          reject(new Error(xhr +
            'An error occurred loading while loading: ' +
            entry.url));
        }
      );
    }));
  }

Promise.all takes the promise array texturePromises as argument. Doing so makes the browser wait for all the promises to resolve, when they do we can load the geometry and the material.

  // load the geometry and the textures
  Promise.all(texturePromises).then(loadedTextures => {

    var geometry = new THREE.SphereGeometry(radius, segments, segments);
    var material = new THREE.MeshPhongMaterial({
      map: textures.map.val,
      bumpMap: textures.bumpMap.val,
      bumpScale: 0.005,
      specularMap: textures.specularMap.val,
      specular: new THREE.Color('grey')
    });

    var earth = that.earth = new THREE.Mesh(geometry, material);
    that.add(earth);
  });

For the cloud sphere only one texture is necessary:

  // clouds
  loader.load('n_amer_clouds.png', map => {
    var geometry = new THREE.SphereGeometry(radius + .05, segments, segments);
    var material = new THREE.MeshPhongMaterial({
      map: map,
      transparent: true
    });

    var clouds = that.clouds = new THREE.Mesh(geometry, material);
    that.add(clouds);
  });
}

Globe.prototype = Object.create(THREE.Object3D.prototype);
Globe.prototype.constructor = Globe;

I faced the same problem, but I found another solution without having to modify my batch script.

The only thing that I missed out is at the 'Action' settings - "Start in (Optional)" option.

Go the task properties --> Action tab --> Edit --> Fill up as below:

1. Action: Start a program
2. Program/script: path to your batch script e.g. C:\Users\beruk\bodo.bat
3. Add arguments (optional): <if necessary - depending on your script>
4. Start in (optional): Put the full path to your batch script location e.g. C:\Users\beruk\(Do not put quotes around Start In)

Then Click OK

It works for me. Good Luck!

I had two problems with the accepted answer.

1. It doesn't capture all screens in a multi-monitor setup.
2. The width and height returned by the Screen class are incorrect when display scaling is used and your application is not declared dpiAware.

Here's my updated solution using the Screen.AllScreens static property and calling EnumDisplaySettings using p/invoke to get the real screen resolution.

using System.Drawing;
using System.Linq;
using System.Runtime.InteropServices;
using System.Windows.Forms;

class Program
{
    const int ENUM_CURRENT_SETTINGS = -1;

    static void Main()
    {
        foreach (Screen screen in Screen.AllScreens)
        {
            DEVMODE dm = new DEVMODE();
            dm.dmSize = (short)Marshal.SizeOf(typeof(DEVMODE));
            EnumDisplaySettings(screen.DeviceName, ENUM_CURRENT_SETTINGS, ref dm);

            using (Bitmap bmp = new Bitmap(dm.dmPelsWidth, dm.dmPelsHeight))
            using (Graphics g = Graphics.FromImage(bmp))
            {
                g.CopyFromScreen(dm.dmPositionX, dm.dmPositionY, 0, 0, bmp.Size);
                bmp.Save(screen.DeviceName.Split('\\').Last() + ".png");
            }
        }
    }

    [DllImport("user32.dll")]
    public static extern bool EnumDisplaySettings(string lpszDeviceName, int iModeNum, ref DEVMODE lpDevMode);

Your activity must have

public void insertIntoDb(View v) {
...
} 

not Fragment .

If you don't want the above in activity. initialize button in fragment and set listener to the same.

<Button
    android:id="@+id/btn_conferma" // + missing

Then

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

   View view = inflater.inflate(R.layout.fragment_rssitem_detail,
    container, false);
   Button button = (Button) view.findViewById(R.id.btn_conferma);
   button.setOnClickListener(new OnClickListener()
   {
             @Override
             public void onClick(View v)
             {
                // do something
             } 
   }); 
   return view;
}

byte[] a = new byte[50];

char [] cArray= System.Text.Encoding.ASCII.GetString(a).ToCharArray();

From the URL thedixon posted

http://bytes.com/topic/c-sharp/answers/250261-byte-char

You cannot ToCharArray the byte without converting it to a string first.

To quote Jon Skeet there

There's no need for the copying here - just use Encoding.GetChars. However, there's no guarantee that ASCII is going to be the appropriate encoding to use.

You can use native JS to test for the existence of an object:

if (document.getElementById('elemId') instanceof Object){
    // do something here
}

Don't forget, jQuery is nothing more than a sophisticated (and very useful) wrapper around native Javascript commands and properties

If you want to add a bounding box, use a rectangle:

ax = plt.gca()
r = matplotlib.patches.Rectangle((.5, .5), .25, .1, fill=False)
ax.add_artist(r)

typename and class are interchangeable in the basic case of specifying a template:

template<class T>
class Foo
{
};

and

template<typename T>
class Foo
{
};

are equivalent.

Having said that, there are specific cases where there is a difference between typename and class.

The first one is in the case of dependent types. typename is used to declare when you are referencing a nested type that depends on another template parameter, such as the typedef in this example:

template<typename param_t>
class Foo
{
    typedef typename param_t::baz sub_t;
};

The second one you actually show in your question, though you might not realize it:

template < template < typename, typename > class Container, typename Type >

When specifying a template template, the class keyword MUST be used as above -- it is not interchangeable with typename in this case (note: since C++17 both keywords are allowed in this case).

You also must use class when explicitly instantiating a template:

template class Foo<int>;

I'm sure that there are other cases that I've missed, but the bottom line is: these two keywords are not equivalent, and these are some common cases where you need to use one or the other.

$result = If ($condition) {"true"} Else {"false"}

Everything else is incidental complexity and thus to be avoided.

For use in or as an expression, not just an assignment, wrap it in $(), thus:

write-host  $(If ($condition) {"true"} Else {"false"}) 

The solution above won't work if the original string has no spaces.

Try this:

var title = "This is your title";
var shortText = jQuery.trim(title).substring(0, 10)
                          .trim(this) + "...";

Use a resize sensor from the css-element-queries library:

https://github.com/marcj/css-element-queries

new ResizeSensor(jQuery('#myElement'), function() {
    console.log('myelement has been resized');
});

It uses a event based approach and doesn't waste your cpu time. Works in all browsers incl. IE7+.

The Proxy pattern might help you:

(function() {
    // log all calls to setArray
    var proxied = jQuery.fn.setArray;
    jQuery.fn.setArray = function() {
        console.log( this, arguments );
        return proxied.apply( this, arguments );
    };
})();

The above wraps its code in a function to hide the "proxied"-variable. It saves jQuery's setArray-method in a closure and overwrites it. The proxy then logs all calls to the method and delegates the call to the original. Using apply(this, arguments) guarantees that the caller won't be able to notice the difference between the original and the proxied method.

if you want to get the data in the entire row, you can use this combination below

tableModel.getDataVector().elementAt(jTable.getSelectedRow());

Where "tableModel" is the model for the table that can be accessed like so

(DefaultTableModel) jTable.getModel();

this will return the entire row data.

I hope this helps somebody

We can get a list of files inside a folder on the file system using various golang standard library functions.

1. filepath.Walk
2. ioutil.ReadDir
3. os.File.Readdir

package main

import (
    "fmt"
    "io/ioutil"
    "log"
    "os"
    "path/filepath"
)

func main() {
    var (
        root  string
        files []string
        err   error
    )

    root := "/home/manigandan/golang/samples"
    // filepath.Walk
    files, err = FilePathWalkDir(root)
    if err != nil {
        panic(err)
    }
    // ioutil.ReadDir
    files, err = IOReadDir(root)
    if err != nil {
        panic(err)
    }
    //os.File.Readdir
    files, err = OSReadDir(root)
    if err != nil {
        panic(err)
    }

    for _, file := range files {
        fmt.Println(file)
    }
}

1. Using filepath.Walk

The path/filepath package provides a handy way to scan all the files in a directory, it will automatically scan each sub-directories in the directory.

func FilePathWalkDir(root string) ([]string, error) {
    var files []string
    err := filepath.Walk(root, func(path string, info os.FileInfo, err error) error {
        if !info.IsDir() {
            files = append(files, path)
        }
        return nil
    })
    return files, err
}

2. Using ioutil.ReadDir

ioutil.ReadDir reads the directory named by dirname and returns a list of directory entries sorted by filename.

func IOReadDir(root string) ([]string, error) {
    var files []string
    fileInfo, err := ioutil.ReadDir(root)
    if err != nil {
        return files, err
    }

    for _, file := range fileInfo {
        files = append(files, file.Name())
    }
    return files, nil
}

3. Using os.File.Readdir

Readdir reads the contents of the directory associated with file and returns a slice of up to n FileInfo values, as would be returned by Lstat, in directory order. Subsequent calls on the same file will yield further FileInfos.

func OSReadDir(root string) ([]string, error) {
    var files []string
    f, err := os.Open(root)
    if err != nil {
        return files, err
    }
    fileInfo, err := f.Readdir(-1)
    f.Close()
    if err != nil {
        return files, err
    }

    for _, file := range fileInfo {
        files = append(files, file.Name())
    }
    return files, nil
}

The Javadoc generation can be skipped by setting the property maven.javadoc.skip to true [1], i.e.

-Dmaven.javadoc.skip=true

(and not false)

Another advantage of using the '[[' operator is that it works both with data.frame and data.table. So if the function has to be made running for both data.frame and data.table, and you want to extract a column from it as a vector then

data[["column_name"]] 

is best.

add disable="true" to html field Example :disable

<amexio-text-input formControlName="LastName" disable="true" [(ngModel)]="emplpoyeeRegistration.lastName" [field-label]="'Last Name'" [place-holder]="'Please enter last name'" [allow-blank]="true" [error-msg]="'errorMsg'" [enable-popover]="true" [min-length]="2"
[min-error-msg]="'Minimum 2 char allowed'" [max-error-msg]="'Maximum 20 char allowed'" name="xyz" [max-length]="20">
[icon-feedback]="true">
</amexio-text-input>

Use EntityScanner if you can bear external dependency.It will inject your all entity classes seamlessly even from multiple packages. Just add following line after configuration setup.

Configuration configuration = new Configuration().configure();    
EntityScanner.scanPackages("com.fz.epms.db.model.entity").addTo(configuration);
// And following depencency if you are using Maven
<dependency>
        <groupId>com.github.v-ladynev</groupId>
        <artifactId>fluent-hibernate-core</artifactId>
        <version>0.3.1</version>
</dependency>

This way you don't need to declare all entities in hibernate mapping file.

Create a table layout panel with two columns in your form and name it tlpFields.

Then, simply add new control to table layout panel (in this case I added 5 labels in column-1 and 5 textboxes in column-2).

tlpFields.RowStyles.Clear();  //first you must clear rowStyles

for (int ii = 0; ii < 5; ii++)
{
    Label l1= new Label();
    TextBox t1 = new TextBox();

    l1.Text = "field : ";

    tlpFields.Controls.Add(l1, 0, ii);  // add label in column0
    tlpFields.Controls.Add(t1, 1, ii);  // add textbox in column1

    tlpFields.RowStyles.Add(new RowStyle(SizeType.Absolute,30)); // 30 is the rows space
}

Finally, run the code.

Just use the serialize PHP function:

<?php
$myArray = array('1', '2');
$seralizedArray = serialize($myArray);
?>

However, if you are using simple arrays like that you might as well use implode and explode.Use a blank array instead of new.

There are much more hexeditors on Linux/Unix....

I use hexedit on Ubuntu

sudo apt-get install hexedit

This depends upon scenarios.

Let's say you have some business functionality and you need to process something with that value further but having null value at time of processing would impact it.

Then, in that case, you can use Optional<?>.

String nullName = null;

String name = Optional.ofNullable(nullName)
                      .map(<doSomething>)
                      .orElse("Default value in case of null");

I have encountered the same problem (in my case with Samsung mobile browsers) and therefore I stumbled upon this question.

Thanks to Calsal's answer I found something that I believe will exclude virtually all desktop browsers because it seems to be recognized by the mobile browsers I tried (see screenshot from a compiled table: CSS pointer feature detection table ).

MDN web docs state that

The pointer CSS @media feature can be used to apply styles based on whether the user's primary input mechanism is a pointing device, and if so, how accurate it is

.

What I discovered is that pointer: coarse is something that is unknown to all desktop browsers in the attached table but known to all mobile browsers in the same table. This seems to be most effective choice because all other pointer keyword values give inconsistent results.

Hence you could construct a media query like Calsal described but slightly modified. It makes use of a reversed logic to rule out all touch devices.

Sass mixin:

@mixin hover-supported {    
    /* 
     * https://developer.mozilla.org/en-US/docs/Web/CSS/@media/pointer 
     * coarse: The primary input mechanism includes a pointing device of limited accuracy.
     */
    @media not all and (pointer: coarse) {
        &:hover {
            @content;
        }
    }
}

a {
    color:green;
    border-color:blue;

    @include hover-supported() {
        color:blue;
        border-color:green;
    }
}

Compiled CSS:

a {
  color: green;
  border-color: blue;
}
@media not all and (pointer: coarse) {
  a:hover {
    color: blue;
    border-color: green;
  }
}

It is also described in this gist I created after researching the problem. Codepen for empirical research.

Swift- 4 Xcode 9.1

try this code

you can not store mapper in NSUserDefault, you can only store NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary.

let myData = NSKeyedArchiver.archivedData(withRootObject: myJson)
UserDefaults.standard.set(myData, forKey: "userJson")

let recovedUserJsonData = UserDefaults.standard.object(forKey: "userJson")
let recovedUserJson = NSKeyedUnarchiver.unarchiveObject(with: recovedUserJsonData)

The idea of retrying the query in case of Deadlock exception is good, but it can be terribly slow, since mysql query will keep waiting for locks to be released. And incase of deadlock mysql is trying to find if there is any deadlock, and even after finding out that there is a deadlock, it waits a while before kicking out a thread in order to get out from deadlock situation.

What I did when I faced this situation is to implement locking in your own code, since it is the locking mechanism of mysql is failing due to a bug. So I implemented my own row level locking in my java code:

private HashMap<String, Object> rowIdToRowLockMap = new HashMap<String, Object>();
private final Object hashmapLock = new Object();
public void handleShortCode(Integer rowId)
{
    Object lock = null;
    synchronized(hashmapLock)
    {
      lock = rowIdToRowLockMap.get(rowId);
      if (lock == null)
      {
          rowIdToRowLockMap.put(rowId, lock = new Object());
      }
    }
    synchronized (lock)
    {
        // Execute your queries on row by row id
    }
}

I'm using Excel 2003 -

The problem with using conditional formatting here is that you can't reference another worksheet or workbook in your conditions. What you can to do is set some column on sheet 1 equal to the appropriate column on sheet 2 (in your example =Sheet2!B6). I used Column F in my example below. Then you can use conditional formatting. Select the cell at Sheet 1, row , column 1 and then go to the conditional formatting menu. Choose "Formula Is" from the drop down and set the condition to "=$F$6=4". Click on the format button and then choose the Patterns tab. Choose the color you want and you're done.

You can use the format painter tool to apply conditional formatting to other cells, but be aware that by default Excel uses absolute references in the conditions. If you want them to be relative you'll need to remove the dollar signs from the condition.

You can have up to 3 conditions applied to a cell (use the add >> button at the bottom of the Conditional formatting dialog) so if the last row is fixed (for example, you know that it will always be row 10) you can use it as a condition to set the background color to none. Assuming that the last value you care about is in row 10 then (still assuming that you've set column F on sheet1 to the corresponding cells on sheet 2) then set the 1st condition to Formula Is =$F$10="" and the pattern to None. Make it the first condition and it will override any following conflicting statements.

First you need to export HTTP_PROXY. Second, you need to read man sudo carefully, and pay attention to the -E flag. This works:

$ export HTTP_PROXY=foof
$ sudo -E bash -c 'echo $HTTP_PROXY'

Here is the quote from the man page:

-E, --preserve-env
             Indicates to the security policy that the user wishes to preserve their
             existing environment variables.  The security policy may return an error
             if the user does not have permission to preserve the environment.

You have two possible ways of doing it:

• do not redirect user upon error and display {{ form_errors(form) }} within template file
• access error array as $form->getErrors()

if you want infos from the actual running batchfile, try this :

@echo off
set myNameFull=%0
echo myNameFull     %myNameFull%
set myNameShort=%~n0
echo myNameShort    %myNameShort%
set myNameLong=%~nx0
echo myNameLong     %myNameLong%
set myPath=%~dp0
echo myPath         %myPath%
set myLogfileWpath=%myPath%%myNameShort%.log
echo myLogfileWpath %myLogfileWpath%

more samples? C:> HELP CALL

%0 = parameter 0 = batchfile %1 = parameter 1 - 1st par. passed to batchfile... so you can try that stuff (e.g. "~dp") between 1st (e.g. "%") and last (e.g. "1") also for parameters

You can run chrome with the --unsafely-treat-insecure-origin-as-secure="http://example.com" flag (replacing "example.com" with the origin you actually want to test), which will treat that origin as secure for this session. Note that you also need to include the --user-data-dir=/test/only/profile/dir to create a fresh testing profile for the flag to work.

For example if use Windows, Click Start and run.

chrome --unsafely-treat-insecure-origin-as-secure="http://localhost:8100"  --user-data-dir=C:\testprofile

I used another solution (by @satprem rath) already present in this chain.

To find the min value of age in the dataframe:

df.agg(min("age")).show()

+--------+
|min(age)|
+--------+
|      29|
+--------+

edit: to add more context.

While the above method printed the result, I faced issues when assigning the result to a variable to reuse later.

Hence, to get only the int value assigned to a variable:

from pyspark.sql.functions import max, min  

maxValueA = df.agg(max("A")).collect()[0][0]
maxValueB = df.agg(max("B")).collect()[0][0]

Few mentions about it:

• it uses cursors instead of a blocking while loop
• it can print progress (uncomment if needed)
• it can exit after a few attempts (uncomment the IF at the end)
• it displays all records
• you can fine tune it as needed

DISCLAIMERS:

• DO NOT run it in production environments!
• It is slow. If the DB is accessed by other services/users, please add " WITH (NOLOCK) " after every table name in all the selects, especially the dynamic select ones.
• It does not validate/protect against all sorts of SQL injection options.
• If your DB is huge, prepare yourself for some sleep, make sure the query will not be killed after a few minutes.
• It casts some values to string, including ints/bigints/smallints/tinyints. If you don't need those, put them at the same exclusion lists with the timestamps at the top of the script.

Exact transfer to Angular2+ is as below:

<button (click)="myFunc()"></button>

also in your component file:

import { Component, OnInit } from "@angular/core";

@Component({
  templateUrl:"button.html" //this is the component which has the above button html
})

export class App implements OnInit{
  constructor(){}

  ngOnInit(){

  }

  myFunc(){
    console.log("function called");
  }
}

Working on Mac I followed the answer of Sean Patrick Floyd placing a settings.xml like above in my user folder /Users/user/.m2/

But this did not help. So I opened a Terminal and did a ls -la on the folder. This was showing

-rw-r--r--@

thus staff and everone can at least read the file. So I wondered if the message isn't wrong and if the real cause is the lack of write permissions. I set the file to:

-rw-r--rw-@

This did it. The message disappeared.

General

Single elements of a tuple a can be accessed -in an indexed array-like fashion-

via a[0], a[1], ... depending on the number of elements in the tuple.

Example

If your tuple is a=(3,"a")

• a[0] yields 3,
• a[1] yields "a"

Concrete answer to question

def tup():
  return (3, "hello")

tup() returns a 2-tuple.

In order to "solve"

i = 5 + tup()  # I want to add just the three

you select the 3 by

tup()[0|    #first element

so in total

i = 5 + tup()[0]

Alternatives

Go with namedtuple that allows you to access tuple elements by name (and by index). Details at https://docs.python.org/3/library/collections.html#collections.namedtuple

>>> import collections
>>> MyTuple=collections.namedtuple("MyTuple", "mynumber, mystring")
>>> m = MyTuple(3, "hello")
>>> m[0]
3
>>> m.mynumber
3
>>> m[1]
'hello'
>>> m.mystring
'hello'

Expanding on Brian Camire's Answer:

Using =MEDIAN(IF($A$1:$A$6="Airline",$B$1:$B$6,"")) with CTRL+SHIFT+ENTER will include blank cells in the calculation. Blank cells will be evaluated as 0 which results in a lower median value. The same is true if using the average funtion. If you don't want to include blank cells in the calculation, use a nested if statement like so:

=MEDIAN(IF($A$1:$A$6="Airline",IF($B$1:$B$6<>"",$B$1:$B$6)))

Don't forget to press CTRL+SHIFT+ENTER to treat the formula as an "array formula".

The best answer here is to use all(), which is the builtin for this situation. We combine this with a generator expression to produce the result you want cleanly and efficiently. For example:

>>> items = [[1, 2, 0], [1, 2, 0], [1, 2, 0]]
>>> all(flag == 0 for (_, _, flag) in items)
True
>>> items = [[1, 2, 0], [1, 2, 1], [1, 2, 0]]
>>> all(flag == 0 for (_, _, flag) in items)
False

Note that all(flag == 0 for (_, _, flag) in items) is directly equivalent to all(item[2] == 0 for item in items), it's just a little nicer to read in this case.

And, for the filter example, a list comprehension (of course, you could use a generator expression where appropriate):

>>> [x for x in items if x[2] == 0]
[[1, 2, 0], [1, 2, 0]]

If you want to check at least one element is 0, the better option is to use any() which is more readable:

>>> any(flag == 0 for (_, _, flag) in items)
True

I fixed this using Guid for each key like this: Generating Guid:

guid() {
    return this.s4() + this.s4() + '-' + this.s4() + '-' + this.s4() + '-' +
        this.s4() + '-' + this.s4() + this.s4() + this.s4();
}

s4() {
    return Math.floor((1 + Math.random()) * 0x10000)
        .toString(16)
        .substring(1);
}

And then assigning this value to markers:

{this.state.markers.map(marker => (
              <MapView.Marker
                  key={this.guid()}
                  coordinate={marker.coordinates}
                  title={marker.title}
              />
          ))}

I my case the error was a result of me not assigning my return value to a variable. The following caused the error message:

return new JavaScriptSerializer().Serialize("hello");

I changed it to:

string H = "hello";
return new JavaScriptSerializer().Serialize(H);

Without the variable JSON is unable to properly format the data.

// @HostListener('scroll', ['$event']) // for scroll events of the current element
@HostListener('window:scroll', ['$event']) // for window scroll events
onScroll(event) {
  ...
}

or

<div (scroll)="onScroll($event)"></div>

Here, to get the text of the menu that triggered the event (does not seem to have any id):

 $(document).ready(function() 
 {
    $('ul.art-vmenu li').click(function(e) 
    { 
     alert($(this).find("span.t").text());
    });
 });

Try this:

declare @var char(3)
set @var='[%]'
select Address from Accomodation where Address like '%'+@var+'%' 

You must use [] cancels the effect of wildcard, so you read % as a normal character, idem about character _

@Daniel Thompson mentions that he had forgotten to add {"Content-Type": "application/json"} in the request. He was able to change the request, however, changing requests is not always possible (we are working on the server here).

In my case I needed to force content-type: text/plain to be parsed as json.

If you cannot change the content-type of the request, try using the following code:

app.use(express.json({type: '*/*'}));

Instead of using express.json() globally, I prefer to apply it only where needed, for instance in a POST request:

app.post('/mypost', express.json({type: '*/*'}), (req, res) => {
  // echo json
  res.json(req.body);
});

I would use this syntax to set the index value into an attribute of the HTML element:

Angular >= 2

You have to use let to declare the value rather than #.

<ul>
    <li *ngFor="let item of items; let i = index" [attr.data-index]="i">
        {{item}}
    </li>
</ul>

Angular = 1

<ul>
    <li *ngFor="#item of items; #i = index" [attr.data-index]="i">
        {{item}}
    </li>
</ul>

Here is the updated plunkr: http://plnkr.co/edit/LiCeyKGUapS5JKkRWnUJ?p=preview.

I prefer:

cin.clear();
fflush(stdin);

There's an example where cin.ignore just doesn't cut it, but I can't think of it at the moment. It was a while ago when I needed to use it (with Mingw).

However, fflush(stdin) is undefined behavior according to the standard. fflush() is only meant for output streams. fflush(stdin) only seems to work as expected on Windows (with GCC and MS compilers at least) as an extension to the C standard.

So, if you use it, your code isn't going to be portable.

See Using fflush(stdin).

Also, see http://ubuntuforums.org/showpost.php?s=9129c7bd6e5c8fd67eb332126b59b54c&p=452568&postcount=1 for an alternative.

Spring has org.springframework.core.io.Resource which is designed for such situations. From context.xml you can pass classpath to the bean

<bean class="test.Test1">
        <property name="path" value="classpath:/test/test1.xml" />
    </bean>

and you get it in your bean as Resource:

public void setPath(Resource path) throws IOException {
    File file = path.getFile();
    System.out.println(file);
    }

output

D:\workspace1\spring\target\test-classes\test\test1.xml

Now you can use it in new FileReader(file)

In order to protect the security of information being sent to and from your web server, it's a good idea to enable encryption of the communication between clients and the server. This is often called SSL.

So let's set up HTTPS with a self-signed certificate on Apache2. I am going to list the steps which you should follow:

• Install apache2 web-server on your machine. For linux machine open the terminal and type

sudo apt-get install apache2

• After successful installation check the status of apache2 service by executing command

sudo service apache2 status

It should output

• Navigate to browser and type

http://localhost:80

Verify that you get default page for apache2 like this.

• For encrypting a web connection we need certificate from CA (certificate authority) or we can use self signed certificates. Let's create a self signed certificate using the following command.

openssl req -x509 -newkey rsa:2048 -keyout mykey.key -out mycert.pem -days 365 -nodes

Please fill the information accordingly as shown below.

mykey.key and mycert.pem should be created in your present working directory.

• It would be nice we if move certificates and keys at a common place and it will be easy for apache2 web server to find them. So let's execute the following commands

sudo cp mycert.pem /etc/ssl/certs

sudo cp mykey.key /etc/ssl/private

• Let's enable the SSL mode on your server

sudo a2enmod ssl

It should output like this

• Let's configure apache2 to use self signed certificate and key which we have generated above.

sudo vi /etc/apache2/sites-available/default-ssl.conf

Please find these two lines and replace them with your cert and key paths.

Initial

Final

• Enable the site

cd /etc/apache2/sites-available/

sudo a2ensite default-ssl.conf

• Restart the apache2 service

sudo service apache2 restart

• Verify the apache2 web-server on HTTPS. Open your browser again and type

https://localhost:443

It should output something like this with a warning that page you are about to view is not secure because we have configured the server with self-signed certificate.

• Congratulations you have configured your apache2 with HTTPS endpoint , now click on advanced --> add exception --> confirm security exception , you will see the default page again.

There are, as i recall, two distributions of the gnu toolchain for windows: mingw and cygwin.

I'd expect cygwin work - a lot of effort has been made to make that a "stadard" posix environment.

The mingw toolchain uses msvcrt.dll for its runtime and thus will probably expose msvcrt's "thread" api: _beginthread which is defined in <process.h>

This may be old, but if anyone has the same problem try changing unitname to just name in the PersistenceContext annotation:

From

@PersistenceContext(unitName="educationPU")

to

@PersistenceContext(name="educationPU")
