Try this test:

any(substring in string for substring in substring_list)

It will return True if any of the substrings in substring_list is contained in string.

Note that there is a Python analogue of Marc Gravell's answer in the linked question:

from itertools import imap
any(imap(string.__contains__, substring_list)) 

In Python 3, you can use map directly instead:

any(map(string.__contains__, substring_list))

Probably the above version using a generator expression is more clear though.

Quick summary, you can do either:

1. Include the JavaFX modules via --module-path and --add-modules like in José's answer.

   OR

2. Once you have JavaFX libraries added to your project (either manually or via maven/gradle import), add the module-info.java file similar to the one specified in this answer. (Note that this solution makes your app modular, so if you use other libraries, you will also need to add statements to require their modules inside the module-info.java file).

This answer is a supplement to Jose's answer.

The situation is this:

1. You are using a recent Java version, e.g. 13.
2. You have a JavaFX application as a Maven project.
3. In your Maven project you have the JavaFX plugin configured and JavaFX dependencies setup as per Jose's answer.
4. You go to the source code of your main class which extends Application, you right-click on it and try to run it.
5. You get an IllegalAccessError involving an "unnamed module" when trying to launch the app.

Excerpt for a stack trace generating an IllegalAccessError when trying to run a JavaFX app from Intellij Idea:

Exception running application org.jewelsea.demo.javafx.springboot.Main

OK, now you are kind of stuck and have no clue what is going on.

What has actually happened is this:

1. Maven has successfully downloaded the JavaFX dependencies for your application, so you don't need to separately download the dependencies or install a JavaFX SDK or module distribution or anything like that.
2. Idea has successfully imported the modules as dependencies to your project, so everything compiles OK and all of the code completion and everything works fine.

So it seems everything should be OK. BUT, when you run your application, the code in the JavaFX modules is failing when trying to use reflection to instantiate instances of your application class (when you invoke launch) and your FXML controller classes (when you load FXML). Without some help, this use of reflection can fail in some cases, generating the obscure IllegalAccessError. This is due to a Java module system security feature which does not allow code from other modules to use reflection on your classes unless you explicitly allow it (and the JavaFX application launcher and FXMLLoader both require reflection in their current implementation in order for them to function correctly).

This is where some of the other answers to this question, which reference module-info.java, come into the picture.

So let's take a crash course in Java modules:

• https://www.baeldung.com/java-9-modularity

The key part is this:

4.9. Opens

If we need to allow reflection of private types, but we don't want all of our code exposed, we can use the opens directive to expose specific packages.

But remember, this will open the package up to the entire world, so make sure that is what you want:

module my.module { opens com.my.package; }

So, perhaps you don't want to open your package to the entire world, then you can do:

4.10. Opens … To

Okay, so reflection is great sometimes, but we still want as much security as we can get from encapsulation. We can selectively open our packages to a pre-approved list of modules, in this case, using the opens…to directive:

module my.module { opens com.my.package to moduleOne, moduleTwo, etc.; }

So, you end up creating a src/main/java/module-info.java class which looks like this:

module org.jewelsea.demo.javafx.springboot {
    requires javafx.fxml;
    requires javafx.controls;
    requires javafx.graphics;
    opens org.jewelsea.demo.javafx.springboot to javafx.graphics,javafx.fxml;
}

Where, org.jewelsea.demo.javafx.springboot is the name of the package which contains the JavaFX Application class and JavaFX Controller classes (replace this with the appropriate package name for your application). This tells the Java runtime that it is OK for classes in the javafx.graphics and javafx.fxml to invoke reflection on the classes in your org.jewelsea.demo.javafx.springboot package. Once this is done, and the application is compiled and re-run things will work fine and the IllegalAccessError generated by JavaFX's use of reflection will no longer occur.

But what if you don't want to create a module-info.java file

If instead of using the the Run button in the top toolbar of IDE to run your application class directly, you instead:

1. Went to the Maven window in the side of the IDE.
2. Chose the javafx maven plugin target javafx.run.
3. Right-clicked on that and chose either Run Maven Build or Debug....

Then the app will run without the module-info.java file. I guess this is because the maven plugin is smart enough to dynamically include some kind of settings which allows the app to be reflected on by the JavaFX classes even without a module-info.java file, though I don't know how this is accomplished.

To get that setting transferred to the Run button in the top toolbar, right-click on the javafx.run Maven target and choose the option to Create Run/Debug Configuration for the target. Then you can just choose Run from the top toolbar to execute the Maven target.

In Python, there is a distinction between bound and unbound methods.

Basically, a call to a member function (like method_one), a bound function

a_test.method_one()

is translated to

Test.method_one(a_test)

i.e. a call to an unbound method. Because of that, a call to your version of method_two will fail with a TypeError

>>> a_test = Test() 
>>> a_test.method_two()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: method_two() takes no arguments (1 given) 

You can change the behavior of a method using a decorator

class Test(object):
    def method_one(self):
        print "Called method_one"

    @staticmethod
    def method_two():
        print "Called method two"

The decorator tells the built-in default metaclass type (the class of a class, cf. this question) to not create bound methods for method_two.

Now, you can invoke static method both on an instance or on the class directly:

>>> a_test = Test()
>>> a_test.method_one()
Called method_one
>>> a_test.method_two()
Called method_two
>>> Test.method_two()
Called method_two

Short and sweet:

def remove_prefix(text, prefix):
    return text[text.startswith(prefix) and len(prefix):]

Have you tried this?

Out = subprocess.Popen('/usr/local/bin/script hostname = actual_server_name -p LONGLIST'.split(), shell=False,stdout=subprocess.PIPE,stderr=subprocess.PIPE) 

Edited per the apt comment from @J.F.Sebastian

You can transfer value from controller using ViewData[""].

ViewData["hdnFlag"] = userId;
return View();

Now, In you view.

@{
    var localVar = ViewData["hdnFlag"]
}
<input type="hidden" asp-for="@localVar" />

Hope this will help...

please try to execute java from

C:\Program Files\Java\jdk1.7.0_10\bin

i.e from the location where java is installed.

If it is successful, it means that the error lies somewhere in the classpath.

Also, this guy seems to have had the same problem as yours, check it out

I'm going to add an answer to try to clear up a few things here as there seems to be some confusion. The main issue is that people are asking the wrong question, or at least not being specific enough.

What does a computer's "domain" actually mean?

When we talk about a computer's "domain", there are several things that we might be referring to. What follows is not an exhaustive list, but it covers the most common cases:

• A user or computer security principal may belong to an Active Directory domain.
• The network stack's primary DNS search suffix may be referred to as the computer's "domain".
• A DNS name that resolves to the computer's IP address may be referred to as the computer's "domain".

Which one do I want?

This is highly dependent on what you are trying to do. The original poster of this question was looking for the computer's "Active Directory domain", which probably means they are looking for the domain to which either the computer's security principal or a user's security principal belongs. Generally you want these when you are trying to talk to Active Directory in some way. Note that the current user principal and the current computer principal are not necessarily in the same domain.

Pieter van Ginkel's answer is actually giving you the local network stack's primary DNS suffix (the same thing that's shown in the top section of the output of ipconfig /all). In the 99% case, this is probably the same as the domain to which both the computer's security principal and the currently authenticated user's principal belong - but not necessarily. Generally this is what you want when you are trying to talk to devices on the LAN, regardless of whether or not the devices are anything to do with Active Directory. For many applications, this will still be a "good enough" answer for talking to Active Directory.

The last option, a DNS name, is a lot fuzzier and more ambiguous than the other two. Anywhere between zero and infinity DNS records may resolve to a given IP address - and it's not necessarily even clear which IP address you are interested in. user2031519's answer refers to the value of HTTP_HOST, which is specifically useful when determining how the user resolved your HTTP server in order to send the request you are currently processing. This is almost certainly not what you want if you are trying to do anything with Active Directory.

How do I get them?

Domain of the current user security principal

This one's nice and simple, it's what Tim's answer is giving you.

System.Environment.UserDomainName

Domain of the current computer security principal

This is probably what the OP wanted, for this one we're going to have to ask Active Directory about it.

System.DirectoryServices.ActiveDirectory.Domain.GetComputerDomain()

This one will throw a ActiveDirectoryObjectNotFoundException if the local machine is not part of domain, or the domain controller cannot be contacted.

Network stack's primary DNS suffix

This is what Pieter van Ginkel's answer is giving you. It's probably not exactly what you want, but there's a good chance it's good enough for you - if it isn't, you probably already know why.

System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName

DNS name that resolves to the computer's IP address

This one's tricky and there's no single answer to it. If this is what you are after, comment below and I will happily discuss your use-case and help you to work out the best solution (and expand on this answer in the process).

Removing a Single Attribute on a Single File

See Bavarious's answer.

To Remove All Extended Attributes On a Single File

Use xattr with the -c flag to "clear" the attributes:

xattr -c yourfile.txt

To Remove All Extended Attributes On Many Files

To recursively remove extended attributes on all files in a directory, combine the -c "clear" flag with the -r recursive flag:

xattr -rc /path/to/directory

A Tip for Mac OS X Users

Have a long path with spaces or special characters?

Open Terminal.app and start typing xattr -rc, include a trailing space, and then then drag the file or folder to the Terminal.app window and it will automatically add the full path with proper escaping.

I seem to have a blind spot as regards your html structure, but I think that this is what you're looking for. It should find the currently-selected option from the select input, assign its text to the newVal variable and then apply that variable to the value attribute of the #costLabel label:

jQuery

$(document).ready(
  function() {
    $('select[name=package]').change(
      function(){
        var newText = $('option:selected',this).text();
        $('#costLabel').text('Total price: ' + newText);
      }
      );
  }
  );

html:

  <form name="thisForm" id="thisForm" action="#" method="post">
  <fieldset>
    <select name="package" id="package">
        <option value="standard">Standard - &euro;55 Monthly</option>
        <option value="standardAnn">Standard - &euro;49 Monthly</option>            
        <option value="premium">Premium - &euro;99 Monthly</option>
        <option value="premiumAnn" selected="selected">Premium - &euro;89 Monthly</option>            
        <option value="platinum">Platinum - &euro;149 Monthly</option>
        <option value="platinumAnn">Platinum - &euro;134 Monthly</option>   
    </select>
  </fieldset>
    
    <fieldset>
      <label id="costLabel" name="costLabel">Total price: </label>
    </fieldset>
  </form>

Working demo of the above at: JS Bin

First let me explain about the algorithm down below. If the array contains no elements then return 1, Then in a loop check if the current element of the array is larger then the previous element by 2 then there is the first smallest missing integer, return it. If the current element is consecutive to the previous element then the current smallest missing integer is the current integer + 1.

    Array.sort(A);

    if(A.Length == 0) return 1;

    int last = (A[0] < 1) ? 0 : A[0];

    for (int i = 0; i < A.Length; i++)
    {
        if(A[i] > 0){
            if (A[i] - last > 1) return last + 1;
            else last = A[i];
        } 
    }

    return last + 1;

The best thing I have found (that seems to work in all browsers) for centering an image, or any element, horizontally is to create a CSS class and include the following parameters:

CSS

.center {
    position: relative;          /* where the next element will be automatically positioned */
    display: inline-block;       /* causes element width to shrink to fit content */
    left: 50%;                   /* moves left side of image/element to center of parent element */
    transform: translate(-50%);  /* centers image/element on "left: 50%" position */
}

You can then apply the CSS class you created to your tag as follows:

HTML

<img class="center" src="image.jpg" />

You can also inline the CSS in your element(s) by doing the following:

<img style="position: relative; display: inline-block; left: 50%; transform: translate(-50%);" src ="image.jpg" />

...but I wouldn't recommend writing CSS inline because then you have to make multiple changes in all your tags using your centering CSS code if you ever want to change the style.

Actually, you can also do it with the iteration method. Because sometimes we might need to use the iteration method instead of the built-in epochs method to visualize the training results after each iteration.

history = [] #Creating a empty list for holding the loss later
for iteration in range(1, 3):
    print()
    print('-' * 50)
    print('Iteration', iteration)
    result = model.fit(X, y, batch_size=128, nb_epoch=1) #Obtaining the loss after each training
    history.append(result.history['loss']) #Now append the loss after the training to the list.
    start_index = random.randint(0, len(text) - maxlen - 1)
print(history)

This way allows you to get the loss you want while maintaining your iteration method.

Be sure you use com.fasterxml.jackson everywhere. I spent much time to find it out.

<properties>
  <fasterxml.jackson.version>2.9.2</fasterxml.jackson.version>
</properties>

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-annotations -->
<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>${fasterxml.jackson.version}</version>
</dependency>

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>${fasterxml.jackson.version}</version>
</dependency>

Then use @JsonManagedReference and @JsonBackReference.

Finally, you can serialize your model to JSON:

import com.fasterxml.jackson.databind.ObjectMapper;

ObjectMapper mapper = new ObjectMapper();
String json = mapper.writeValueAsString(model);

You can use html2canvas plugin and jsPDF both. Process order: html to png & png to pdf

Example code:

jQuery('#part1').html2canvas({
    onrendered: function( canvas ) {
        var img1 = canvas.toDataURL('image/png');
    }
});
jQuery('#part2').html2canvas({
    onrendered: function( canvas ) {
        var img2 = canvas.toDataURL('image/png');
    }
});
jQuery('#part3').html2canvas({
    onrendered: function( canvas ) {
        var img3 = canvas.toDataURL('image/png');
    }
});
var doc = new jsPDF('p', 'mm');
doc.addImage( img1, 'PNG', 0, 0, 210, 297); // A4 sizes
doc.addImage( img2, 'PNG', 0, 90, 210, 297); // img1 and img2 on first page

doc.addPage();
doc.addImage( img3, 'PNG', 0, 0, 210, 297); // img3 on second page
doc.save("file.pdf");

The install.packages command looks through the .libPaths variable. Here's what mine defaults to on OSX:

> .libPaths()
[1] "/Library/Frameworks/R.framework/Resources/library"

I don't install packages there by default, I prefer to have them installed in my home directory. In my .Rprofile, I have this line:

.libPaths( "/Users/tex/lib/R" )

This adds the directory "/Users/tex/lib/R" to the front of the .libPaths variable.

I had the same problem but I use -w 0 option to send only one packet and quit. You should use this command :

echo -n "hello" | nc -4u -w0 localhost 8000

Assuming the class variable is z, you can use:

with(df, plot(x, y, col = z))

however, it's important that z is a factor variable, as R internally stores factors as integers.

This way, 1 is 'black', 2 is 'red', 3 is 'green, ....

Another important thing I noticed is that when running the application it ignores capitals in file/folders in the resources folder where it doesn't ignore it while running as a jar. Therefore, in case your file is in the resources folder under Testfolder/messages.txt

@Autowired
ApplicationContext appContext;

// this will work when running the application, but will fail when running as jar
appContext.getResource("classpath:testfolder/message.txt");

Therefore, don't use capitals in your resources or also add those capitals in your constructor of ClassPathResource:

appContext.getResource("classpath:Testfolder/message.txt");

here are my personal ~/.vimrc backup settings

OSQL -E -d <*databasename*> -Q "exec sp_msforeachtable 'sp_spaceused [?]'" > result.txt

You can use the QuerySetChain class below. When using it with Django's paginator, it should only hit the database with COUNT(*) queries for all querysets and SELECT() queries only for those querysets whose records are displayed on the current page.

Note that you need to specify template_name= if using a QuerySetChain with generic views, even if the chained querysets all use the same model.

from itertools import islice, chain

class QuerySetChain(object):
    """
    Chains multiple subquerysets (possibly of different models) and behaves as
    one queryset.  Supports minimal methods needed for use with
    django.core.paginator.
    """

    def __init__(self, *subquerysets):
        self.querysets = subquerysets

    def count(self):
        """
        Performs a .count() for all subquerysets and returns the number of
        records as an integer.
        """
        return sum(qs.count() for qs in self.querysets)

    def _clone(self):
        "Returns a clone of this queryset chain"
        return self.__class__(*self.querysets)

    def _all(self):
        "Iterates records in all subquerysets"
        return chain(*self.querysets)

    def __getitem__(self, ndx):
        """
        Retrieves an item or slice from the chained set of results from all
        subquerysets.
        """
        if type(ndx) is slice:
            return list(islice(self._all(), ndx.start, ndx.stop, ndx.step or 1))
        else:
            return islice(self._all(), ndx, ndx+1).next()

In your example, the usage would be:

pages = Page.objects.filter(Q(title__icontains=cleaned_search_term) |
                            Q(body__icontains=cleaned_search_term))
articles = Article.objects.filter(Q(title__icontains=cleaned_search_term) |
                                  Q(body__icontains=cleaned_search_term) |
                                  Q(tags__icontains=cleaned_search_term))
posts = Post.objects.filter(Q(title__icontains=cleaned_search_term) |
                            Q(body__icontains=cleaned_search_term) | 
                            Q(tags__icontains=cleaned_search_term))
matches = QuerySetChain(pages, articles, posts)

Then use matches with the paginator like you used result_list in your example.

The itertools module was introduced in Python 2.3, so it should be available in all Python versions Django runs on.

I met the same question just now,my problem lies in the ignorance of blank behind the "user.email" and "[email protected]".

 git config --global user.email "[email protected]"

I hope it will help you.

That's the easiest I could think of (TESTED) and it works!!

char message[50];
fgets(message, 50, stdin);
for( i = 0, j = 0; i < strlen(message); i++){
        message[i-j] = message[i];
        if(message[i] == ' ')
            j++;
}
message[i] = '\0';

in my case it happens when I try add types to Promise.all handler:

Promise.all([1,2]).then(([num1, num2]: [number, number])=> console.log('res', num1));

If remove : [number, number], the error is gone.

parent.abc() will only work on same domain due to security purposes. i tried this workaround and mine worked perfectly.

<head>
    <script>
    function abc() {
        alert("sss");
    }

    // window of the iframe
    var innerWindow = document.getElementById('myFrame').contentWindow;
    innerWindow.abc= abc;

    </script>
</head>
<body>
    <iframe id="myFrame">
        <a onclick="abc();" href="#">Click Me</a>
    </iframe>
</body>

Hope this helps. :)

I would use a for loop to iterate over the lines in the text file:

for line in my_text:
    outputfile.writelines(data_parser(line, reps))

If you want to read the file line-by-line instead of loading the whole thing at the start of the script you could do something like this:

inputfile = open('test.dat')
outputfile = open('test.csv', 'w')

# sample text string, just for demonstration to let you know how the data looks like
# my_text = '"2012-06-23 03:09:13.23",4323584,-1.911224,-0.4657288,-0.1166382,-0.24823,0.256485,"NAN",-0.3489428,-0.130449,-0.2440527,-0.2942413,0.04944348,0.4337797,-1.105218,-1.201882,-0.5962594,-0.586636'

# dictionary definition 0-, 1- etc. are there to parse the date block delimited with dashes, and make sure the negative numbers are not effected
reps = {'"NAN"':'NAN', '"':'', '0-':'0,','1-':'1,','2-':'2,','3-':'3,','4-':'4,','5-':'5,','6-':'6,','7-':'7,','8-':'8,','9-':'9,', ' ':',', ':':',' }

for i in range(4): inputfile.next() # skip first four lines
for line in inputfile:
    outputfile.writelines(data_parser(line, reps))

inputfile.close()
outputfile.close()

I have created some sample code which creates new variables using a variety of ways that I can think of. It looks like the first 3 ways create values, and the last two create references.

package main

import "fmt"

type Config struct {
    host string
    port float64
}

func main() {
    //value
    var c1 Config
    c2 := Config{}
    c3 := *new(Config)

    //reference
    c4 := &Config{}
    c5 := new(Config)

    fmt.Println(&c1 == nil)
    fmt.Println(&c2 == nil)

Use ` backticks for MYSQL reserved words...

table name "table" is reserved word for MYSQL...

so your query should be as follows...

$sql="INSERT INTO `table` (`username`, `password`)
VALUES
('$_POST[username]','$_POST[password]')";

In addition to existing answers:

RUN apt-get update && apt-get install -y gnupg

-y flag agrees to terms during installation process. It is important not to break the build

The simple version is 0x is a prefix denoting a hexadecimal number, source.

So the value you're computing is after the prefix, in this case 10.

But that is not the number 10. The most significant bit 1 denotes the hex value while 0 denotes the units.

So the simple math you would do is

0x10

1 * 16 + 0 = 16

Note - you use 16 because hex is base 16.

Another example:

0xF7

15 * 16 + 7 = 247

You can get a list of values by searching for a hex table. For instance in this chart notice F corresponds with 15.

I prefer using egrep, though in my test with a genuine file with blank line your approach worked fine (though without quotation marks in my test). This worked too:

egrep -v "^(\r?\n)?$" filename.txt

Should work.

Here's a working example:

http://jsfiddle.net/rhpNc/

Excerpt:

function loadIframe(iframeName, url) {
    var $iframe = $('#' + iframeName);
    if ($iframe.length) {
        $iframe.attr('src',url);
        return false;
    }
    return true;
}

If some of your services are balking into ulimits, it's sometimes easier to put appropriate commands into service's init-script. For example, when Apache is reporting

[alert] (11)Resource temporarily unavailable: apr_thread_create: unable to create worker thread

Try to put ulimit -s unlimited into /etc/init.d/httpd. This does not require a server reboot.

find . -type f | 
sed -n "s/\(.*\)factory\.py$/& \1service\.py/p" | 
xargs -p -n 2 mv

eg will rename all files in the cwd with names ending in "factory.py" to be replaced with names ending in "service.py"

explanation:

1) in the sed cmd, the -n flag will suppress normal behavior of echoing input to output after the s/// command is applied, and the p option on s/// will force writing to output if a substitution is made. since a sub will only be made on match, sed will only have output for files ending in "factory.py"

2) in the s/// replacement string, we use "& " to interpolate the entire matching string, followed by a space character, into the replacement. because of this, it's vital that our RE matches the entire filename. after the space char, we use "\1service.py" to interpolate the string we gulped before "factory.py", followed by "service.py", replacing it. So for more complex transformations youll have to change the args to s/// (with an re still matching the entire filename)

example output:

foo_factory.py foo_service.py
bar_factory.py bar_service.py

3) we use xargs with -n 2 to consume the output of sed 2 delimited strings at a time, passing these to mv (i also put the -p option in there so you can feel safe when running this). voila.

 $deleted = $_POST['checkbox'];
 $sql = "DELETE FROM $tbl_name WHERE id IN (".implode(",", $deleted ) . ")";

In Active Directory environment, it's important to know:

• All member machines synchronizes with any domain controller.

• In a domain, all domain controllers synchronize from the PDC Emulator (PDCe) of that domain.

• The PDC Emulator of a domain should synchronize with local or NTP.

It's important to consider this when setting the time in vmware or configuring the time sync.

X-XSS-Protection is a HTTP header understood by Internet Explorer 8 (and newer versions). This header lets domains toggle on and off the "XSS Filter" of IE8, which prevents some categories of XSS attacks. IE8 has the filter activated by default, but servers can switch if off by setting

   X-XSS-Protection: 0

To anyone else who finds this older question, you can now download all old versions.

Xcode -> Preferences -> Components (Click on Simulators tab).

Install all the versions you want/need.

To show all installed simulators:

Target -> In dropdown "deployment target" choose the installed version with lowest version nr.

You should now see all your available simulators in the dropdown.

Use maxlength

<input type="text" maxlength="10" />

& is HTML for "Start of a character reference".

& is the character reference for "An ampersand".

&current; is not a standard character reference and so is an error (browsers may try to perform error recovery but you should not depend on this).

If you used a character reference for a real character (e.g. ™) then it (™) would appear in the URL instead of the string you wanted.

(Note that depending on the version of HTML you use, you may have to end a character reference with a ;, which is why &trade= will be treated as ™. HTML 4 allows it to be ommited if the next character is a non-word character (such as =) but some browsers (Hello Internet Explorer) have issues with this).

anyItem is a method and the System.out.println call is after your return statement so that won't compile anyway since it is unreachable.

Might want to re-write it like:

import java.util.ArrayList;
import java.util.Random;

public class Catalogue
{
    private Random randomGenerator;
    private ArrayList<Item> catalogue;

    public Catalogue()
    { 
        catalogue = new ArrayList<Item>();
        randomGenerator = new Random();
    }

    public Item anyItem()
    {
        int index = randomGenerator.nextInt(catalogue.size());
        Item item = catalogue.get(index);
        System.out.println("Managers choice this week" + item + "our recommendation to you");
        return item;
    }
}

Interestingly enough, the foreach loop is actually the most efficient way of doing this.

Since the OP specifically asked about efficiency, it should be pointed out that all the current answers are in fact much less efficient than a foreach.

I did a benchmark on this with php 5.4, and the reset/key pointer method (accepted answer) seems to be about 7 times slower than a foreach. Other approaches manipulating the entire array (array_keys, array_flip) are obviously even slower than that and become much worse when working with a large array.

Foreach is not inefficient at all, feel free to use it!

Edit 2015-03-03:

Benchmark scripts have been requested, I don't have the original ones but made some new tests instead. This time I found the foreach only about twice as fast as reset/key. I used a 100-key array and ran each method a million times to get some noticeable difference, here's code of the simple benchmark:

$array = [];
for($i=0; $i < 100; $i++)
    $array["key$i"] = $i;

for($i=0, $start = microtime(true); $i < 1000000; $i++) {
    foreach ($array as $firstKey => $firstValue) {
        break;
    }
}
echo "foreach to get first key and value: " . (microtime(true) - $start) . " seconds <br />";

for($i=0, $start = microtime(true); $i < 1000000; $i++) {
    $firstValue = reset($array);
    $firstKey = key($array);
}
echo "reset+key to get first key and value: " . (microtime(true) - $start) . " seconds <br />";

for($i=0, $start = microtime(true); $i < 1000000; $i++) {
    reset($array);
    $firstKey = key($array);
}
echo "reset+key to get first key: " . (microtime(true) - $start) . " seconds <br />";


for($i=0, $start = microtime(true); $i < 1000000; $i++) {
    $firstKey = array_keys($array)[0];
}
echo "array_keys to get first key: " . (microtime(true) - $start) . " seconds <br />";

On my php 5.5 this outputs:

foreach to get first key and value: 0.15501809120178 seconds 
reset+key to get first key and value: 0.29375791549683 seconds 
reset+key to get first key: 0.26421809196472 seconds 
array_keys to get first key: 10.059751987457 seconds

The 2 highest upvoted answers are correct. As of today, the only thing I needed to change (from default settings) was to enable generation using dot instead of the built-in generator.

Some important notes:

• Doxygen will not generate an actual full diagram of all classes in the project. It will generate a separate image for each hierarchy. If you have multiple, unrelated class hierarchies you will get multiple images.
• All these diagrams can be found in html/inherits.html or (from the website navigation) classes => class hierarchy => "Go to the textual class hierarchy".
• This is a C++ question, so let's talk about templates. Especially if you inherit from T.
  • Each template instantiation will be correctly considered a different type by Doxygen. Types which inherit from different instantations will have different parent classes on the diagram.
  • If a class template foo inherits from T and the T template type parameter has a default, such default will be assumed. If there is a type bar which inherits from foo<U> where U is different than the default, bar will have a foo<U> parent. foo<> and bar<U> will not have a common parent.
  • If there are multiple class templates which inherit from at least one of their template parameters, Doxygen will assume a common parent for these class templates as long as the template type parameters have exactly the same names in the code. This incentivizes for consistency in naming.
  • CRTP and reverse CRTP just work.
  • Recursive template inheritance trees are not expanded. Any variant instantiation will be displayed to inherit from variant<Ts...>.
  • Class templates with no instantiations are being drawn. They will have a <...> string in their name representing type and non-type parameters which did not have defaults.
  • Class template full and partial specializations are also being drawn. Doxygen generates correct graphs if specializations inherit from different types.

This can be caused by running a 64bit .NET runtime against a 32bit Oracle client. This can happen if your server you are running the app on it 64 bit. It will run the .NET app with the 64bit runtime. You can set the CPU flag on your project in VS to run in the 32bit runtime.

You can simplify Joe Kington's code using the axparameter of figure.colorbar() with a list of axes. From the documentation:

ax

None | parent axes object(s) from which space for a new colorbar axes will be stolen. If a list of axes is given they will all be resized to make room for the colorbar axes.

import numpy as np
import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=2, ncols=2)
for ax in axes.flat:
    im = ax.imshow(np.random.random((10,10)), vmin=0, vmax=1)

fig.colorbar(im, ax=axes.ravel().tolist())

plt.show()

Using pymongo, you need to have both databases on same mongod, I did the following:

db = original database
db2 = database to be copied to

cursor = db["<collection to copy from>"].find()
for data in cursor:
    db2["<new collection>"].insert(data)

The rules (which did not change in C++11):

• Reserved in any scope, including for use as implementation macros:
  • identifiers beginning with an underscore followed immediately by an uppercase letter
  • identifiers containing adjacent underscores (or "double underscore")
• Reserved in the global namespace:
  • identifiers beginning with an underscore
• Also, everything in the std namespace is reserved. (You are allowed to add template specializations, though.)

From the 2003 C++ Standard:

17.4.3.1.2 Global names [lib.global.names]

Certain sets of names and function signatures are always reserved to the implementation:

• Each name that contains a double underscore (__) or begins with an underscore followed by an uppercase letter (2.11) is reserved to the implementation for any use.
• Each name that begins with an underscore is reserved to the implementation for use as a name in the global namespace.¹⁶⁵

¹⁶⁵⁾ Such names are also reserved in namespace ::std (17.4.3.1).

Because C++ is based on the C standard (1.1/2, C++03) and C99 is a normative reference (1.2/1, C++03) these also apply, from the 1999 C Standard:

7.1.3 Reserved identifiers

Each header declares or defines all identifiers listed in its associated subclause, and optionally declares or defines identifiers listed in its associated future library directions subclause and identifiers which are always reserved either for any use or for use as file scope identifiers.

• All identifiers that begin with an underscore and either an uppercase letter or another underscore are always reserved for any use.
• All identifiers that begin with an underscore are always reserved for use as identifiers with file scope in both the ordinary and tag name spaces.
• Each macro name in any of the following subclauses (including the future library directions) is reserved for use as specified if any of its associated headers is included; unless explicitly stated otherwise (see 7.1.4).
• All identifiers with external linkage in any of the following subclauses (including the future library directions) are always reserved for use as identifiers with external linkage.¹⁵⁴
• Each identifier with file scope listed in any of the following subclauses (including the future library directions) is reserved for use as a macro name and as an identifier with file scope in the same name space if any of its associated headers is included.

No other identifiers are reserved. If the program declares or defines an identifier in a context in which it is reserved (other than as allowed by 7.1.4), or defines a reserved identifier as a macro name, the behavior is undefined.

If the program removes (with #undef) any macro definition of an identifier in the first group listed above, the behavior is undefined.

¹⁵⁴⁾ The list of reserved identifiers with external linkage includes errno, math_errhandling, setjmp, and va_end.

Other restrictions might apply. For example, the POSIX standard reserves a lot of identifiers that are likely to show up in normal code:

• Names beginning with a capital E followed a digit or uppercase letter:
  • may be used for additional error code names.
• Names that begin with either is or to followed by a lowercase letter
  • may be used for additional character testing and conversion functions.
• Names that begin with LC_ followed by an uppercase letter
  • may be used for additional macros specifying locale attributes.
• Names of all existing mathematics functions suffixed with f or l are reserved
  • for corresponding functions that operate on float and long double arguments, respectively.
• Names that begin with SIG followed by an uppercase letter are reserved
  • for additional signal names.
• Names that begin with SIG_ followed by an uppercase letter are reserved
  • for additional signal actions.
• Names beginning with str, mem, or wcs followed by a lowercase letter are reserved
  • for additional string and array functions.
• Names beginning with PRI or SCN followed by any lowercase letter or X are reserved
  • for additional format specifier macros
• Names that end with _t are reserved
  • for additional type names.

While using these names for your own purposes right now might not cause a problem, they do raise the possibility of conflict with future versions of that standard.

Personally I just don't start identifiers with underscores. New addition to my rule: Don't use double underscores anywhere, which is easy as I rarely use underscore.

After doing research on this article I no longer end my identifiers with _t as this is reserved by the POSIX standard.

The rule about any identifier ending with _t surprised me a lot. I think that is a POSIX standard (not sure yet) looking for clarification and official chapter and verse. This is from the GNU libtool manual, listing reserved names.

CesarB provided the following link to the POSIX 2004 reserved symbols and notes 'that many other reserved prefixes and suffixes ... can be found there'. The POSIX 2008 reserved symbols are defined here. The restrictions are somewhat more nuanced than those above.

Your code is valid (with one exception). It is required to have code between BEGIN and END.

Replace

--do some work

with

print ''

I think maybe you saw "END and not "AND"

Here is answer to your question.

By default maven looks in ../pom.xml for relativePath. Use empty <relativePath/> tag instead.

public void onActivityResult(int requestCode, int resultCode, Intent intent) 
{
  if (requestCode == PICK_CONTACT && intent != null) //here check whether intent is null R not
  {  
  }
}

because without selecting any contact it will give an exception. so better to check this condition.

On the confirmation page, don't put the content in editable controls, just write them to the page.

For those who are trying to get an X Window application working from Windows from Linux:

What worked for me was to setup xming server on my windows machine, set X11 forwarding option in putty when I connect to the linux host and put in my windows ip address with the display port and then the display variable with my windows IP address:0.0

Dont forget to add the linux hosts IP address to the X0.hosts file to ensure that the xming server accepts traffic from that host. Took me a while to figure that out.

I wasted several hours trying to get the latest version of FontAwesome 5.2.0 working with AngularCLI 6.0.3 and Material Design. I followed the npm installation instructions off of the FontAwesome website

Their latest docs instruct you do install using the following:

npm install @fortawesome/fontawesome-free

After wasting several hours I finally uninstalled it and installed font awesome using the following command (this installs FontAwesome v4.7.0):

npm install font-awesome --save

Now it's working fine using:

$fa-font-path: "~font-awesome/fonts" !default;
@import "~font-awesome/scss/font-awesome.scss";
<mat-icon fontSet="fontawesome" fontIcon="fa-android"></mat-icon>

You can create a thread just like this:

 Thread thread = new Thread(new Runnable() {
                    public void run() {

                       }
                    });
                thread.start();

Also, you can use Runnable, Asyntask, Timer, TimerTaks and AlarmManager to excecute Threads.

Actually torek told you already how to use the tools much better than I would be able to do. However, in this case I think it is important to point out something peculiar if you follow the guidelines at http://octopress.org/docs/deploying/github/. Namely, you will have multiple github repositories in your setup. First of all the one with all the source code for your website in say the directory $WEBSITE, and then the one with only the static generated files residing in $WEBSITE/_deploy. The funny thing of the setup is that there is a .gitignore file in the $WEBSITE directory so that this setup actually works.

Enough introduction. In this case the error might also come from the repository in _deploy.

cd _deploy

git branch -a
* master
remotes/origin/master
remotes/origin/source

In .git/config you will normally need to find something like this:

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
[remote "origin"]
    url = [email protected]:yourname/yourname.github.io.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master

But in your case the branch master does not have a remote.

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
[remote "origin"]
    url = [email protected]:yourname/yourname.github.io.git
    fetch = +refs/heads/*:refs/remotes/origin/*

Which you can solve by:

cd _deploy
git branch --set-upstream-to=origin/master

So, everything is as torek told you, but it might be important to point out that this very well might concern the _deploy directory rather than the root of your website.

PS: It might be worth to use a shell such as zsh with a git plugin to not be bitten by this thing in the future. It will immediately show that _deploy concerns a different repository.

>>> [int(i) for i in str(12345)]

[1, 2, 3, 4, 5]

When passing an array as a parameter, this

void arraytest(int a[])

means exactly the same as

void arraytest(int *a)

so you are modifying the values in main.

For historical reasons, arrays are not first class citizens and cannot be passed by value.

There are several correct ways to display a down-pointing and upward-pointing triangle.

Method 1 : use decimal HTML entity

HTML :

▲
▼

Method 2 : use hexidecimal HTML entity

HTML :

▲
▼

Method 3 : use character directly

HTML :

?
?

Method 4 : use CSS

HTML :

<span class='icon-up'></span>
<span class='icon-down'></span>

CSS :

.icon-up:before {
    content: "\25B2";
}

.icon-down:before {
    content: "\25BC";
}

Each of these three methods should have the same output. For other symbols, the same three options exist. Some even have a fourth option, allowing you to use a string based reference (eg. ♥ to display ?).

You can use a reference website like Unicode-table.com to find which icons are supported in UNICODE and which codes they correspond with. For example, you find the values for the down-pointing triangle at http://unicode-table.com/en/25BC/.

Note that these methods are sufficient only for icons that are available by default in every browser. For symbols like ?,?,?,?,?,? or ?, this is far less likely to be the case. While it is possible to provide cross-browser support for other UNICODE symbols, the procedure is a bit more complicated.

If you want to know how to add support for less common UNICODE characters, see Create webfont with Unicode Supplementary Multilingual Plane symbols for more info on how to do this.

Background images

A totally different strategy is the use of background-images instead of fonts. For optimal performance, it's best to embed the image in your CSS file by base-encoding it, as mentioned by eg. @weasel5i2 and @Obsidian. I would recommend the use of SVG rather than GIF, however, is that's better both for performance and for the sharpness of your symbols.

This following code is the base64 for and SVG version of the icon :

/* size: 0.9kb */
url(data:image/svg+xml;base64,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

When to use background-images or fonts

For many use cases, SVG-based background images and icon fonts are largely equivalent with regards to performance and flexibility. To decide which to pick, consider the following differences:

SVG images

• They can have multiple colors
• They can embed their own CSS and/or be styled by the HTML document
• They can be loaded as a seperate file, embedded in CSS AND embedded in HTML
• Each symbol is represented by XML code or base64 code. You cannot use the character directly within your code editor or use an HTML entity
• Multiple uses of the same symbol implies duplication of the symbol when XML code is embedded in the HTML. Duplication is not required when embedding the file in the CSS or loading it as a seperate file
• You can not use color, font-size, line-height, background-color or other font related styling rules to change the display of your icon, but you can reference different components of the icon as shapes individually.
• You need some knowledge of SVG and/or base64 encoding
• Limited or no support in old versions of IE

Icon fonts

• An icon can have but one fill color, one background color, etc.
• An icon can be embedded in CSS or HTML. In HTML, you can use the character directly or use an HTML entity to represent it.
• Some symbols can be displayed without the use of a webfont. Most symbols cannot.
• Multiple uses of the same symbol implies duplication of the symbol when your character embedded in the HTML. Duplication is not required when embedding the file in the CSS.
• You can use color, font-size, line-height, background-color or other font related styling rules to change the display of your icon
• You need no special technical knowledge
• Support in all major browsers, including old versions of IE

Personally, I would recommend the use of background-images only when you need multiple colors and those color can't be achieved by means of color, background-color and other color-related CSS rules for fonts.

The main benefit of using SVG images is that you can give different components of a symbol their own styling. If you embed your SVG XML code in the HTML document, this is very similar to styling the HTML. This would, however, result in a web page that uses both HTML tags and SVG tags, which could significantly reduce the readability of a webpage. It also adds extra bloat if the symbol is repeated across multiple pages and you need to consider that old versions of IE have no or limited support for SVG.

Doesn't work for all videos, very depends on monetization settings or something like that.

You can always just use jQuery to add a class, .addClass or .toggleClass. Then you can keep all your styles in your CSS and out of your scripts.

Here is a program to compare the two ways suggested so far

import (
    "fmt"

    "github.com/bradfitz/iter"
)

func p(i int) {
    fmt.Println(i)
}

func plain() {
    for i := 0; i < 10; i++ {
        p(i)
    }
}

func with_iter() {
    for i := range iter.N(10) {
        p(i)
    }
}

func main() {
    plain()
    with_iter()
}

So you can see that the iter solution is considerably more expensive even though it is fully inlined in the setup phase. In the loop phase there is an extra instruction in the loop, but it isn't too bad.

I'd use the simple for loop.

It may not be obvious how to break a shell command into a sequence of arguments, especially in complex cases. shlex.split() can do the correct tokenization for args (I'm using Blender's example of the call):

import shlex
from subprocess import Popen, PIPE
command = shlex.split('swfdump /tmp/filename.swf/ -d')
process = Popen(command, stdout=PIPE, stderr=PIPE)
stdout, stderr = process.communicate()

I know this is a bit old, but I thought I would provide another tip. In my situation, I inherited this application that I had to maintain. The VS2008 project came with the same string in C/C++->OutputFIles->"ObjectFIleName" and "Program Database File Name" (for both platforms Win32 and x64). So when I built Win32 platform, it built fine, but when I tried to build x64, I got the error:

\Debug64\Objects\common.obj : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64'

Obviously, both patforms were storing common.obj at the same location, so when I tried to build x64, the linker took the existing object file, which was x86.

To fix I just replaced the existing string with the macro "$(IntDir)\" for x64 (no quotes), and made sure that the macro resolved to the correct path, as in the rest of the projects. That solved my problem.

Also you can try to use

display:inline-block;

if you would like the span element to align horizontally.

Incase you would like to align span elements vertically, just use

 display:block;

Try changing the Web Client request authentication part to:

NetworkCredential myCreds = new NetworkCredential(userName, passWord);
client.Credentials = myCreds;

Then make your call, seems to work fine for me.

This is portable - at least between ORACLE and PostgreSQL:

select t.* from table t 
where not exists(select 1 from table ti where ti.attr > t.attr);

You can use the watch mode to detect changes:

Do everything at atomic level. So first check if watch method itself is getting called or not by consoling something inside. Once it has been established that watch is getting called, smash it out with your business logic.

watch: { 
  myProp: function() {
   console.log('Prop changed')
  }
}

This one $("#yourDiv").load(" #yourDiv > *"); is the best if you are planning to just reload a <div>

Make sure to use an id and not a class. Also, remember to paste <script src="https://code.jquery.com/jquery-3.5.1.js"></script> in the <head> section of the html file, if you haven't already. In opposite case it won't work.

Just using

$().popover({container: 'body'})

could be not enough when displaying popover over a BootstrapDialog modal, which also uses body as container and has a higher z-index.

I come with this fix which uses internals of Bootstrap3 (may not work with 2.x / 4.x) but most of modern Bootstrap installations are 3.x.

self.$anchor.on('shown.bs.popover', function(ev) {
    var tipCSS = self.$anchor.data('tipCSS');
    if (tipCSS !== undefined) {
        self.$anchor.data('bs.popover').$tip.css(tipCSS);
    }
    // ...
});

Such way different popovers may have different z-index, some are under BootstrapDialog modal, while another ones are over it.

For windows, there are automatic installer packages available at this site

It includes most of the python packages.

But the best way for it is of course using pip.

Press Ctrl+Alt+Delete and Task Manager will pop up. Find the Python command running, right click on it and and click Stop or Kill.

If non of the answers worked

For me was .Net Framework version compatibility issue of the one i'm using was older then what is referencing

From properties => Application then target framework

enum Enum{ Banana, Orange, Apple } ;
static const char * EnumStrings[] = { "bananas & monkeys", "Round and orange", "APPLE" };

const char * getTextForEnum( int enumVal )
{
  return EnumStrings[enumVal];
}

Yes to both questions. The using statement gets compiled into a try/finally block

using (SqlConnection connection = new SqlConnection(connectionString))
{
}

is the same as

SqlConnection connection = null;
try
{
    connection = new SqlConnection(connectionString);
}
finally
{
   if(connection != null)
        ((IDisposable)connection).Dispose();
}

Edit: Fixing the cast to Disposable http://msdn.microsoft.com/en-us/library/yh598w02.aspx

This should answer that question, and then some.

The second line, if (obj.GetType() == typeof(ClassA)) {}, is faster, for those that don't want to read the article.

(Be aware that they don't do the same thing)

A simple way to use modals is with eModal!

Ex from github:

1. Link to eModal.js <script src="//rawgit.com/saribe/eModal/master/dist/eModal.min.js"></script>

2. use eModal to display a modal for alert, ajax, prompt or confirm

   // Display an alert modal with default title (Attention)
   eModal.ajax('your/url.html');

In my case the error was caused by the insufficient memory allocated to the "test" lifecycle of maven. It was fixed by adding <argLine>-Xms3512m -Xmx3512m</argLine> to:

<pluginManagement>
  <plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.16</version>
        <configuration>
            <argLine>-Xms3512m -Xmx3512m</argLine>

Thanks @crazycoder for pointing this out (and also that it is not related to IntelliJ; in this case).

If your tests are forked, they run in a new JVM that doesn't inherit Maven JVM options. Custom memory options must be provided via the test runner in pom.xml, refer to Maven documentation for details, it has very little to do with the IDE.

Here's some code that I ended up writing, based upon @Andrei's answer but without the elegancy/simplicity. The advantage is that it allows a more complex recursive merge and also differs between elements that should be connected with rbind and those that are just connected with c:

# Decided to move this outside the mapply, not sure this is 
# that important for speed but I imagine redefining the function
# might be somewhat time-consuming
mergeLists_internal <- function(o_element, n_element){
  if (is.list(n_element)){
    # Fill in non-existant element with NA elements
    if (length(n_element) != length(o_element)){
      n_unique <- names(n_element)[! names(n_element) %in% names(o_element)]
      if (length(n_unique) > 0){
        for (n in n_unique){
          if (is.matrix(n_element[[n]])){
            o_element[[n]] <- matrix(NA, 
                                     nrow=nrow(n_element[[n]]), 
                                     ncol=ncol(n_element[[n]]))
          }else{
            o_element[[n]] <- rep(NA, 
                                  times=length(n_element[[n]]))
          }
        }
      }

      o_unique <- names(o_element)[! names(o_element) %in% names(n_element)]
      if (length(o_unique) > 0){
        for (n in o_unique){
          if (is.matrix(n_element[[n]])){
            n_element[[n]] <- matrix(NA, 
                                     nrow=nrow(o_element[[n]]), 
                                     ncol=ncol(o_element[[n]]))
          }else{
            n_element[[n]] <- rep(NA, 
                                  times=length(o_element[[n]]))
          }
        }
      }
    }  

    # Now merge the two lists
    return(mergeLists(o_element, 
                      n_element))

  }
  if(length(n_element)>1){
    new_cols <- ifelse(is.matrix(n_element), ncol(n_element), length(n_element))
    old_cols <- ifelse(is.matrix(o_element), ncol(o_element), length(o_element))
    if (new_cols != old_cols)
      stop("Your length doesn't match on the elements,",
           " new element (", new_cols , ") !=",
           " old element (", old_cols , ")")
  }

  return(rbind(o_element, 
               n_element, 
               deparse.level=0))
  return(c(o_element, 
           n_element))
}
mergeLists <- function(old, new){
  if (is.null(old))
    return (new)

  m <- mapply(mergeLists_internal, old, new, SIMPLIFY=FALSE)
  return(m)
}

Here's my example:

v1 <- list("a"=c(1,2), b="test 1", sublist=list(one=20:21, two=21:22))
v2 <- list("a"=c(3,4), b="test 2", sublist=list(one=10:11, two=11:12, three=1:2))
mergeLists(v1, v2)

This results in:

$a
     [,1] [,2]
[1,]    1    2
[2,]    3    4

$b
[1] "test 1" "test 2"

$sublist
$sublist$one
     [,1] [,2]
[1,]   20   21
[2,]   10   11

$sublist$two
     [,1] [,2]
[1,]   21   22
[2,]   11   12

$sublist$three
     [,1] [,2]
[1,]   NA   NA
[2,]    1    2

Yeah, I know - perhaps not the most logical merge but I have a complex parallel loop that I had to generate a more customized .combine function for, and therefore I wrote this monster :-)

import { timer } from 'rxjs';

await timer(1000).pipe(take(1)).toPromise();

this works better for me

I would recommend reading in the line into a string, then splitting it based on the spaces. For this, you can use the getline(...) function. The trick is having a dynamic sized data structure to hold the strings once it's split. Probably the easiest to use would be a vector.

#include <string>
#include <vector>
...
  string rawInput;
  vector<String> numbers;
  while( getline( cin, rawInput, ' ' ) )
  {
    numbers.push_back(rawInput);
  }

So say the input looks like this:

Enter a number, or numbers separated by a space, between 1 and 1000.
10 5 20 1 200 7

You will now have a vector, numbers, that contains the elements: {"10","5","20","1","200","7"}.

Note that these are still strings, so not useful in arithmetic. To convert them to integers, we use a combination of the STL function, atoi(...), and because atoi requires a c-string instead of a c++ style string, we use the string class' c_str() member function.

while(!numbers.empty())
{
  string temp = numbers.pop_back();//removes the last element from the string
  num = atoi( temp.c_str() ); //re-used your 'num' variable from your code

  ...//do stuff
}

Now there's some problems with this code. Yes, it runs, but it is kind of clunky, and it puts the numbers out in reverse order. Lets re-write it so that it is a little more compact:

#include <string>
...
string rawInput;
cout << "Enter a number, or numbers separated by a space, between 1 and 1000." << endl;
while( getline( cin, rawInput, ' ') )
{
  num = atoi( rawInput.c_str() );
  ...//do your stuff
}

There's still lots of room for improvement with error handling (right now if you enter a non-number the program will crash), and there's infinitely more ways to actually handle the input to get it in a usable number form (the joys of programming!), but that should give you a comprehensive start. :)

Note: I had the reference pages as links, but I cannot post more than two since I have less than 15 posts :/

Edit: I was a little bit wrong about the atoi behavior; I confused it with Java's string->Integer conversions which throw a Not-A-Number exception when given a string that isn't a number, and then crashes the program if the exception isn't handled. atoi(), on the other hand, returns 0, which is not as helpful because what if 0 is the number they entered? Let's make use of the isdigit(...) function. An important thing to note here is that c++ style strings can be accessed like an array, meaning rawInput[0] is the first character in the string all the way up to rawInput[length - 1].

#include <string>
#include <ctype.h>
...
string rawInput;
cout << "Enter a number, or numbers separated by a space, between 1 and 1000." << endl;
while( getline( cin, rawInput, ' ') )
{
  bool isNum = true;
  for(int i = 0; i < rawInput.length() && isNum; ++i)
  {
    isNum = isdigit( rawInput[i]);
  }

  if(isNum)
  {
    num = atoi( rawInput.c_str() );
    ...//do your stuff
  }
  else
    cout << rawInput << " is not a number!" << endl;
}

The boolean (true/false or 1/0 respectively) is used as a flag for the for-loop, which steps through each character in the string and checks to see if it is a 0-9 digit. If any character in the string is not a digit, the loop will break during it's next execution when it gets to the condition "&& isNum" (assuming you've covered loops already). Then after the loop, isNum is used to determine whether to do your stuff, or to print the error message.

This happens due to current branch has no tracking on the branch on the remote. so you can do it with 2 ways.

1. Pull with specific branch name

git pull origin master

2. Or you can specific branch to track to the local branch.

git branch --set-upstream-to=origin/

WinSQL: I wanted to return all records for last month:

where DATE01 between dateadd(month,-1,dateadd(day,1,dateadd(day,-day(today()),today()))) and dateadd(day,-day(today()),today())

This does the same thing:

where month(DATE01) = month(dateadd(month,-1,today())) and year(DATE01) = year(dateadd(month,-1,today()))

Use your mydate object and call getMonth() and getFullYear()

See this for more info: http://www.w3schools.com/jsref/jsref_obj_date.asp

The step of : Select your project and select the "Deployment Descriptor" option and then choose "Generate Deployment Descriptor stub" works fine. The issue is that it is not always the case that we need web.xml, so it is best to append false to pom.xml

The setstate is asynchronous in react, so to see the updated state in console use the callback as shown below (Callback function will execute after the setstate update)

The below method is "not recommended" but for understanding, if you mutate state directly you can see the updated state in the next line. I repeat this is "not recommended"

Just in case someone is looking for user Display Name as opposed to User Name, like me.

Here's the treat :

System.DirectoryServices.AccountManagement.UserPrincipal.Current.DisplayName.

Add Reference to System.DirectoryServices.AccountManagement in your project.

The same error occurs if in DirectoryEntry.Patch is nothing after the symbols "LDAP//:". It is necessary to check the directoryEntry.Path before directorySearcher.FindOne(). Unless explicitly specified domain, and do not need to "LDAP://".

private void GetUser(string userName, string domainName)
{
     DirectoryEntry dirEntry = new DirectoryEntry();

     if (domainName.Length > 0)
     {
          dirEntry.Path = "LDAP://" + domainName;
     }

     DirectorySearcher dirSearcher = new DirectorySearcher(dirEntry);
     dirSearcher.SearchScope = SearchScope.Subtree;
     dirSearcher.Filter = string.Format("(&(objectClass=user)(|(cn={0})(sn={0}*)(givenName={0})(sAMAccountName={0}*)))", userName);
     var searchResults = dirSearcher.FindAll();
     //var searchResults = dirSearcher.FindOne();

     if (searchResults.Count == 0)
     {
          MessageBox.Show("User not found");
     }
     else
     {
          foreach (SearchResult sr in searchResults)
          {
              var de = sr.GetDirectoryEntry();
              string user = de.Properties["SAMAccountName"][0].ToString();
              MessageBox.Show(user); 
          }        
     }
}

Compare this, without using nonlocal:

x = 0
def outer():
    x = 1
    def inner():
        x = 2
        print("inner:", x)

    inner()
    print("outer:", x)

outer()
print("global:", x)

# inner: 2
# outer: 1
# global: 0

To this, using nonlocal, where inner()'s x is now also outer()'s x:

x = 0
def outer():
    x = 1
    def inner():
        nonlocal x
        x = 2
        print("inner:", x)

    inner()
    print("outer:", x)

outer()
print("global:", x)

# inner: 2
# outer: 2
# global: 0

If we were to use global, it would bind x to the properly "global" value:

x = 0
def outer():
    x = 1
    def inner():
        global x
        x = 2
        print("inner:", x)

    inner()
    print("outer:", x)

outer()
print("global:", x)

# inner: 2
# outer: 1
# global: 2

You need to reference both Microsoft.ReportViewer.WebForms and Microsoft.ReportViewer.Common and set the CopyLocal property to true. This will result in the dll's being copied to our bin directory (both are necessary).

I know some things have changed in AC 2010. However, the old-fashioned ADODB is, as far as I know, the best way to go in VBA. An Example:

Dim cn As ADODB.Connection
Dim cmd As ADODB.Command
Dim prm As ADODB.Parameter
Dim rs As ADODB.Recordset
Dim colReturn As New Collection

Dim SQL As String
SQL = _
    "SELECT c.ClientID, c.LastName, c.FirstName, c.MI, c.DOB, c.SSN, " & _
    "c.RaceID, c.EthnicityID, c.GenderID, c.Deleted, c.RecordDate " & _
    "FROM tblClient AS c " & _
    "WHERE c.ClientID = @ClientID"

Set cn = New ADODB.Connection
Set cmd = New ADODB.Command

With cn
    .Provider = DataConnection.MyADOProvider
    .ConnectionString = DataConnection.MyADOConnectionString
    .Open
End With

With cmd
    .CommandText = SQL
    .ActiveConnection = cn
    Set prm = .CreateParameter("@ClientID", adInteger, adParamInput, , mlngClientID)
    .Parameters.Append prm
End With

Set rs = cmd.Execute

With rs
    If Not .EOF Then
        Do Until .EOF
            mstrLastName = Nz(!LastName, "")
            mstrFirstName = Nz(!FirstName, "")
            mstrMI = Nz(!MI, "")
            mdDOB = !DOB

            mlngRaceID = Nz(!RaceID, -1)
            mlngEthnicityID = Nz(!EthnicityID, -1)

I've got a YouTube video on this.

Short answer: Use mock when you're passing in the thing that you want mocked, and patch if you're not. Of the two, mock is strongly preferred because it means you're writing code with proper dependency injection.

Silly example:

# Use a mock to test this.
my_custom_tweeter(twitter_api, sentence):
    sentence.replace('cks','x')   # We're cool and hip.
    twitter_api.send(sentence)

# Use a patch to mock out twitter_api. You have to patch the Twitter() module/class 
# and have it return a mock. Much uglier, but sometimes necessary.
my_badly_written_tweeter(sentence):
    twitter_api = Twitter(user="XXX", password="YYY")
    sentence.replace('cks','x') 
    twitter_api.send(sentence)

I just simply make changes on config.inc.php file. There is password in error in this link $cfg['Servers'][$i]['password'] = 'your password '; and now its perfectly worked .

My not very revealing answer:

private String md5(String s) {
    try {
        MessageDigest m = MessageDigest.getInstance("MD5");
        m.update(s.getBytes(), 0, s.length());
        BigInteger i = new BigInteger(1,m.digest());
        return String.format("%1$032x", i);         
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
    return null;
}

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string

escapeRegExp("All of these should be escaped: \ ^ $ * + ? . ( ) | { } [ ]");

>>> "All of these should be escaped: \\ \^ \$ \* \+ \? \. \( \) \| \{ \} \[ \] "

This means it does not match what you will find in the code in the below npm, and does not match what is shown in the below long answer. The comments are also now confusing. My recommendation: use the above, or get it from MDN, and ignore the rest of this answer. -Darren,Nov 2019)

The Long Answer

If you're going to use the function above at least link to this stack overflow post in your code's documentation so that it doesn't look like crazy hard-to-test voodoo.

var escapeRegExp;

(function () {
  // Referring to the table here:
  // https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/regexp
  // these characters should be escaped
  // \ ^ $ * + ? . ( ) | { } [ ]
  // These characters only have special meaning inside of brackets
  // they do not need to be escaped, but they MAY be escaped
  // without any adverse effects (to the best of my knowledge and casual testing)
  // : ! , = 
  // my test "~!@#$%^&*(){}[]`/=?+\|-_;:'\",<.>".match(/[\#]/g)

  var specials = [
        // order matters for these
          "-"
        , "["
        , "]"
        // order doesn't matter for any of these
        , "/"
        , "{"
        , "}"
        , "("
        , ")"
        , "*"
        , "+"
        , "?"
        , "."
        , "\\"
        , "^"
        , "$"
        , "|"
      ]

      // I choose to escape every character with '\'
      // even though only some strictly require it when inside of []
    , regex = RegExp('[' + specials.join('\\') + ']', 'g')
    ;

  escapeRegExp = function (str) {
    return str.replace(regex, "\\$&");
  };

  // test escapeRegExp("/path/to/res?search=this.that")
}());

From the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.

When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of ~/.bashrc.

Thus, if you want to get the same behavior for both login shells and interactive non-login shells, you should put all of your commands in either .bashrc or .bash_profile, and then have the other file source the first one.

Use the in operator: e.g. "key1" in a.

Another way of initializing the array to a common value, would be to actually generate the list of elements in a series of defines:

#define DUP1( X ) ( X )
#define DUP2( X ) DUP1( X ), ( X )
#define DUP3( X ) DUP2( X ), ( X )
#define DUP4( X ) DUP3( X ), ( X )
#define DUP5( X ) DUP4( X ), ( X )
.
.
#define DUP100( X ) DUP99( X ), ( X )

#define DUPx( X, N ) DUP##N( X )
#define DUP( X, N ) DUPx( X, N )

Initializing an array to a common value can easily be done:

#define LIST_MAX 6
static unsigned char List[ LIST_MAX ]= { DUP( 123, LIST_MAX ) };

Note: DUPx introduced to enable macro substitution in parameters to DUP

function get_time($time) {
    $duration = $time / 1000;
    $hours = floor($duration / 3600);
    $minutes = floor(($duration / 60) % 60);
    $seconds = $duration % 60;
    if ($hours != 0)
        echo "$hours:$minutes:$seconds";
    else
        echo "$minutes:$seconds";
}

get_time('1119241');

Sitemaps protocol, which is a way for webmasters to inform search engines about pages on their sites (also used by Google in Webmaster Tools), supports URLs with less than 2048 characters. So if you are planning to use this feature for Search Engine Optimization, take this into account.

EDIT: I thought that the other computer is dead so I'm fixing my answer:

You should export the certificate from the first computer with it's private key and import it in the new computer.

I prefer the iCloud way, backup to iCloud and get it in the new computer.

If you can't do it with some reason, you can revoke the certificate in Apple developers site, then let Xcode to create a new one for you, it'll also create a fresh new private key and store it in your Keychain, just be sure to back it up in your preferred way

I used below ms sql script pattern several times successfully which uses Try-Catch,Commit Transaction- Rollback Transaction,Error Tracking.

Your TRY block will be as follows

 BEGIN TRY
 BEGIN TRANSACTION T
 ----
 //your script block
 ----
 COMMIT TRANSACTION T 
 END TRY

Your CATCH block will be as follows

BEGIN CATCH
DECLARE @ErrMsg NVarChar(4000), 
        @ErrNum Int, 
        @ErrSeverity Int, 
        @ErrState Int, 
        @ErrLine Int, 
        @ErrProc NVarChar(200)
 SELECT @ErrNum = Error_Number(), 
       @ErrSeverity = Error_Severity(), 
       @ErrState = Error_State(), 
       @ErrLine = Error_Line(), 
       @ErrProc = IsNull(Error_Procedure(), '-')
 SET @ErrMsg = N'ErrLine: ' + rtrim(@ErrLine) + ', proc: ' + RTRIM(@ErrProc) + ', 
       Message: '+ Error_Message()

Your ROLLBACK script will be part of CATCH block as follows

IF (@@TRANCOUNT) > 0 
BEGIN
PRINT 'ROLLBACK: ' + SUBSTRING(@ErrMsg,1,4000)
ROLLBACK TRANSACTION T
END
ELSE
BEGIN
PRINT SUBSTRING(@ErrMsg,1,4000);   
END

END CATCH

Above different script blocks you need to use as one block. If any error happens in the TRY block it will go the the CATCH block. There it is setting various details about the error number,error severity,error line ..etc. At last all these details will get append to @ErrMsg parameter. Then it will check for the count of transaction (@@TRANCOUNT >0) , ie if anything is there in the transaction for rollback. If it is there then show the error message and ROLLBACK TRANSACTION. Otherwise simply print the error message.

We have kept our COMMIT TRANSACTION T script towards the last line of TRY block in order to make sure that it should commit the transaction(final change in the database) only after all the code in the TRY block has run successfully.

As in this forum post by Gonzalo Medina, a third way may be:

\documentclass{article}

where:

• "progress" is current progress before the thumb and "secondaryProgress" is the progress after thumb.
• color="#00000000" is a perfect transparency
• NOTE: the file above is from default android res and is for 2.3.7, it is available on android sources at: frameworks/base/core/res/res/drawable/progress_horizontal.xml. For newer versions you must find the default drawable file for the seekbar corresponding to your android version.

after that use it in the layout containing the xml:

<SeekBar
    android:id="@+id/myseekbar"

you can also customize the thumb by using a custom icon seek_thumb.png:

It turns out IntelliJ does not pick up added dependencies from the local Maven repository. We have to tell IntelliJ to reimport the pom.xml.

1. Open the project view in IntelliJ
2. Right click the pom.xml file and select Maven - Reimport
3. If this works for you IntelliJ will add the dependencies to the project
4. Check the if the dependencies you need are added in

One of the many ways it can be achieved is this:

$fileDownloadCount          =  (int) column_data_from_db;
$fileDownloadCount++;

The second line increments the value by 1.

In a sense you're right, although anything lower than 2^8 characters will still register as a byte of data.

If you account for the base character that leaves anything with a VARCHAR < 255 as consuming the same amount of space.

255 is a good baseline definition unless you particularly wish to curtail excessive input.

Kafka message queue and local black lists

I thought about using a messaging system like kafka. Let me explain:

You could have one micro service (let call it userMgmtMs service) for example which is responsible for the login and logout and to produce the JWT token. This token then gets passed to the client.

Now the client can use this token to call different micro services (lets call it pricesMs), within pricesMs there will be NO database check to the users table from which the initial token creation was triggered. This database has only to exist in userMgmtMs. Also the JWT token should include the permissions / roles so that the pricesMs do not need to lookup anything from the DB to allow spring security to work.

Instead of going to the DB in the pricesMs the JwtRequestFilter could provide a UserDetails object created by the data provided in the JWT token (without the password obviously).

So, how to logout or invalidate a token? Since we do not wanna call the database of userMgmtMs with every request for priecesMs (which would introduce quite a lot of unwanted dependencies) a solution could be to use this token blacklist.

Instead of keeping this blacklist central and haveing a dependency on one table from all microservices, I propose to use a kafka message queue.

The userMgmtMs is still responsible for the logout and once this is done it puts it into its own blacklist (a table NOT shared among microservices). In addition it sends a kafka event with the content of this token to a internal kafka service where all other microservices are subscribed to.

Once the other microservices receive the kafka event they will put it as well in their internal blacklist.

Even if some microservices are down at the time of logout they will eventually go up again and will receive the message at a later state.

Since kafka is developed so that clients have their own reference which messages they did read it is ensured that no client, down or up will miss any of this invalid tokens.

The only issue again what I can think of is that the kafka messaging service will again introduce a single point of failure. But it is kind of reversed because if we have one global table where all invalid JWT tokens are saved and this db or micro service is down nothing works. With the kafka approach + client side deletion of JWT tokens for a normal user logout a downtime of kafka would in most cases not even be noticeable. Since the black lists are distributed among all microservies as an internal copy.

In the off case that you need to invalidate a user which was hacked and kafka is down this is where the problems start. In this case changing the secret as a last resort could help. Or just make sure kafka is up before doing so.

Disclaimer: I did not implement this solution yet but somehow I feel that most of the proposed solution negate the idea of the JWT tokens with having a central database lookup. So I was thinking about another solution.

Please let me know what you think, does it make sense or is there an obvious reason why it cant?

On High Sierra

which python

shows the default python but if you downloaded and installed the latest version from python.org you can find it by:

which python3.6

which on my machine shows

/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6

I have faced this issue when I introduced additional supporting libraries in my project IntelliJ IDEA

So for me "File" -> "Invalidate Caches...", and select "Invalidate and Restart" option to fix this.

Why not graph the percentage complete. If you include the last date as a 100% complete value you can force the chart to show the linear trend as well as the actual data. This should give you a reasonable idea of whether you are above or below the line.

I would include a screenshot but not enough rep. Here is a link to one I prepared earlier. Burn Down Chart.

$(function(){    
    if($.browser.msie && $.browser.version <= 9){
        $("[placeholder]").focus(function(){
            if($(this).val()==$(this).attr("placeholder")) $(this).val("");
        }).blur(function(){
            if($(this).val()=="") $(this).val($(this).attr("placeholder"));
        }).blur();

        $("[placeholder]").parents("form").submit(function() {
            $(this).find('[placeholder]').each(function() {
                if ($(this).val() == $(this).attr("placeholder")) {
                    $(this).val("");
                }
            })
        });
    }
});

I had the same problem, It was solved when I checked the below checkbox

• Clean up working copy status
• Break write locks

• Include externals

  SVN Cleanup dialog

Well, in my case, I was running low disk space on my drive where I have my MongoDB data files. I checked MongoDB logs file which stated the following

2015-11-11T21:53:54.717+0500 E JOURNAL [initandlisten] Insufficient free space for journal files 2015-11-11T21:53:54.717+0500 I JOURNAL [initandlisten] Please make at least 3379MB available in C:\wamp\bin\mongodb\data\db\journal or use --smallfiles

All I had to do is clean up some space and fire up the service again.. Worked for me. So All you have to is check your logs file and deal with the problem accordingly.

You should be able to use reduce.

var sum = array.reduce(function(pv, cv) { return pv + cv; }, 0);

Source

And with arrow functions introduced in ES6, it's even simpler:

sum = array.reduce((pv, cv) => pv + cv, 0);

you need to add Content-Length: 0 in your request header.

a very descriptive example of how to test is given here

I have put together a project that can convert some really neat expressions. Check out timestring.

Here are some examples below:

>>> import timestring
>>> timestring.Date('monday, aug 15th 2015 at 8:40 pm')
<timestring.Date 2015-08-15 20:40:00 4491909392>
>>> timestring.Date('monday, aug 15th 2015 at 8:40 pm').date
datetime.datetime(2015, 8, 15, 20, 40)
>>> timestring.Range('next week')
<timestring.Range From 03/10/14 00:00:00 to 03/03/14 00:00:00 4496004880>
>>> (timestring.Range('next week').start.date, timestring.Range('next week').end.date)
(datetime.datetime(2014, 3, 10, 0, 0), datetime.datetime(2014, 3, 14, 0, 0))

For Android Studio add the following to your top-level build.gradle file within the allprojects block

tasks.withType(JavaCompile) {
    options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation" 
}

<project name="Build" basedir="." default="clean">
    <property name="default.build.type" value ="Release"/>

    <target name="clean">
    <echo>Value Buld is now  ${PARAM_BUILD_TYPE} is set</echo>
        <condition property="build.type" value="${PARAM_BUILD_TYPE}" else="${default.build.type}">
            <isset property="PARAM_BUILD_TYPE"/>
        </condition>

       <echo>Value Buld is now  ${PARAM_BUILD_TYPE} is set</echo>
       <echo>Value Buld is now  ${build.type} is set</echo>
    </target>
</project>

In my Case DPARAM_BUILD_TYPE=Debug if it is supplied than, I need to build for for Debug otherwise i need to go for building Release build. I write like above condition it worked and i have tested as below it is working fine for me.

And property ${build.type} we can pass this to other target or macrodef for processing which i am doing in my other ant macrodef.

D:\>ant -DPARAM_BUILD_TYPE=Debug
Buildfile: D:\build.xml
clean:
     [echo] Value Buld is now  Debug is set
     [echo] Value Buld is now  Debug is set
     [echo] Value Buld is now  Debug is set
main:
BUILD SUCCESSFUL
Total time: 0 seconds
D:\>ant
Buildfile: D:\build.xml
clean:
     [echo] Value Buld is now  ${PARAM_BUILD_TYPE} is set
     [echo] Value Buld is now  ${PARAM_BUILD_TYPE} is set
     [echo] Value Buld is now  Release is set
main:
BUILD SUCCESSFUL
Total time: 0 seconds

It work for me to implement condition so posted hope it will helpful.

You can do like this using function:

l = [34,56,78,2,3,5,6,8,45,6]  
print ("The list : " + str(l))   
def count_greater30(l):  
    count = 0  
    for i in l:  
        if i > 30:  
            count = count + 1.  
    return count
print("Count greater than 30 is : " + str(count)).  
count_greater30(l)

begin transaction

// execute SQL code here

rollback transaction

If you've already executed the query and want to roll it back, unfortunately your only real option is to restore a database backup. If you're using Full backups, then you should be able to restore the database to a specific point in time.

you can use the Math.abs function to turn negative numbers to positive and keep positives as it is. then you can convert the number to string and provide length. look at this function:

const digitCount = num => Math.abs(num).toString().length;

i found this method the easiest and it works pretty good.

You need to add in the seconds, too:

unsigned long time_in_micros = 1000000 * tv.tv_sec + tv.tv_usec;

Note that this will only last for about 2³²/10⁶ =~ 4295 seconds, or roughly 71 minutes though (on a typical 32-bit system).

I was getting the same error while trying to load simply HTML files that used JSON data to populate the page, so I used used node.js and express to solve the problem. If you do not have node installed, you need to install node first.

1. Install express npm install express

2. Create a server.js file in the root folder of your project, in my case one folder above the files I wanted to server

3. Put something like the following in the server.js file and read about this on the express gihub site:

   var express = require('express');
   var app = express();
   var path = require('path');
   
   // __dirname will use the current path from where you run this file 
   app.use(express.static(__dirname));
   app.use(express.static(path.join(__dirname, '/FOLDERTOHTMLFILESTOSERVER')));
   
   app.listen(8000);
   console.log('Listening on port 8000');
   

4. After you've saved server.js, you can run the server using:

node server.js

5. Go to http://localhost:8000/FILENAME and you should see the HTML file you were trying to load

One indirect solution can be to use std::deque instead. It supports all operations of queue and you can iterate over it just by using for(auto& x:qu). It's much more efficient than using a temporary copy of queue for iteration.

To calculate MD5 hash of CLOB content field with my desired encoding without implicitly recoding content to AL32UTF8, I've used this code:

create or replace function clob2blob(AClob CLOB) return BLOB is
  Result BLOB;
  o1 integer;
  o2 integer;
  c integer;
  w integer;
begin
  o1 := 1;
  o2 := 1;
  c := 0;
  w := 0;
  DBMS_LOB.CreateTemporary(Result, true);
  DBMS_LOB.ConvertToBlob(Result, AClob, length(AClob), o1, o2, 0, c, w);
  return(Result);
end clob2blob;
/

update my_table t set t.hash = (rawtohex(DBMS_CRYPTO.Hash(clob2blob(t.content),2)));

If else condition, also called alternatives in UML terms can indeed be represented in sequence diagrams. Here is a link where you can find some nice resources on the subject http://www.ibm.com/developerworks/rational/library/3101.html

If you need to recal an Activity that is in bacgrounde, from your service, I suggest the following link. Intent.FLAG_ACTIVITY_NEW_TASK is not the solution.

sudo apt-get -y install python-software-properties && \
sudo apt-get -y install software-properties-common && \

You need the libssl-dev and libffi-dev if especially you are trying to install python's cryptography libraries or python libs that depend on it(eg ansible)

Most of the simple programs have computation time in milli-seconds. So, i suppose, you will find this useful.

#include <time.h>
#include <stdio.h>

int main(){
    clock_t start = clock();
    // Execuatable code
    clock_t stop = clock();
    double elapsed = (double)(stop - start) * 1000.0 / CLOCKS_PER_SEC;
    printf("Time elapsed in ms: %f", elapsed);
}

If you want to compute the runtime of the entire program and you are on a Unix system, run your program using the time command like this time ./a.out

SELECT  *  FROM Table1 
WHERE MAKE+MODEL+[Serial Number]  not in
    (select make+model+[serial number] from Table2 
     WHERE make+model+[serial number] IS NOT NULL)

That worked for me, where make+model+[serial number] was one field name

In batch you could do it like this:

@echo off

setlocal EnableDelayedExpansion

set "string_list=str1 str2 str3 ... str10"

for %%s in (%string_list%) do (
  set "var=%%sxyz"
  svn co "!var!"
)

If you don't need the variable !var! elsewhere in the loop, you could simplify that to

@echo off

setlocal

set "string_list=str1 str2 str3 ... str10"

for %%s in (%string_list%) do svn co "%%sxyz"

However, like C.B. I'd prefer PowerShell if at all possible:

$string_list = 'str1', 'str2', 'str3', ... 'str10'

$string_list | ForEach-Object {
  $var = "${_}xyz"   # alternatively: $var = $_ + 'xyz'
  svn co $var
}

Again, this could be simplified if you don't need $var elsewhere in the loop:

$string_list = 'str1', 'str2', 'str3', ... 'str10'
$string_list | ForEach-Object { svn co "${_}xyz" }

Here is the way you can do with Javascript Promise.

const getBase64 = (file) => new Promise(function (resolve, reject) {
    let reader = new FileReader();
    reader.readAsDataURL(file);
    reader.onload = () => resolve(reader.result)
    reader.onerror = (error) => reject('Error: ', error);
})

Now, use it in event handler.

const _changeImg = (e) => {
        const file = e.target.files[0];
        let encoded;
        getBase64(file)
          .then((result) => {
            encoded = result;
           })
          .catch(e => console.log(e))
    }

I know this an old question but I just wanted to add if you would like to easily change the height of a UITextField from inside IB then simply change that UITextfield's border type to anything other than the default rounded corner type. Then you can stretch or change height attributes easily from inside the editor.

For the following command

sudo npm install react browserify watchify babelify --save-dev

I got same error

saveError ENOENT: no such file or directory, open '/Users/Path/package.json'

But when I run the command

sudo npm install -gd react browserify watchify babelify --save-dev

then no missing file or directory message appeared.

The solution with TextBoxFor is OK, but if you don't want to see the field like EditBox stylish (it might be a little confusing for the user) involve changes as follows:

1. Razor code before changes

   <div class="editor-field">
        @Html.EditorFor(model => model.Text)
        @Html.ValidationMessageFor(model => model.Text)
   </div>
   

2. After changes

   <!-- New div display-field (after div editor-label) -->
   <div class="display-field">
       @Html.DisplayFor(model => model.Text)
   </div>
   
   <div class="editor-field">
       <!-- change to HiddenFor in existing div editor-field -->
       @Html.HiddenFor(model => model.Text)
       @Html.ValidationMessageFor(model => model.Text)
   </div>
   

Generally, this solution prevents field from editing, but shows value of it. There is no need for code-behind modifications.

One more possibility, if you don't want to use ArgumentCaptor (for example, because you're also using stubbing), is to use Hamcrest Matchers in combination with Mockito.

import org.mockito.Mockito
import org.hamcrest.Matchers
...

Mockito.verify(mockedObject).someMethodOnMockedObject(MockitoHamcrest.argThat(
    Matchers.<SomeObjectAsArgument>hasProperty("propertyName", desiredValue)));

You are using <input name='C[]' in your HTML. This creates an array in PHP when the form is sent.

You are using echo $_POST['C']; to echo that array - this will not work, but instead emit that notice and the word "Array".

Depending on what you did with the rest of the code, you should probably use echo $_POST['C'][0];

Not so hard:

#include <thread>

void Test::runMultiThread()
{
    std::thread t1(&Test::calculate, this,  0, 10);
    std::thread t2(&Test::calculate, this, 11, 20);
    t1.join();
    t2.join();
}

If the result of the computation is still needed, use a future instead:

#include <future>

void Test::runMultiThread()
{
     auto f1 = std::async(&Test::calculate, this,  0, 10);
     auto f2 = std::async(&Test::calculate, this, 11, 20);

     auto res1 = f1.get();
     auto res2 = f2.get();
}

My version of @Merak Marey's Code. I am checking if files exist already and different download directories for .txt and other files

        static void DownloadAll()
    {
        string host = "xxx.xxx.xxx.xxx";
        string username = "@@@";
        string password = "123";string remoteDirectory = "/IN/";
        string finalDir = "";
        string localDirectory = @"C:\filesDN\";
        string localDirectoryZip = @"C:\filesDN\ZIP\";
        using (var sftp = new SftpClient(host, username, password))
        {
            Console.WriteLine("Connecting to " + host + " as " + username);
            sftp.Connect();
            Console.WriteLine("Connected!");
            var files = sftp.ListDirectory(remoteDirectory);

            foreach (var file in files)
            {

                string remoteFileName = file.Name;

                if ((!file.Name.StartsWith(".")) && ((file.LastWriteTime.Date == DateTime.Today)))
                { 

                    if (!file.Name.Contains(".TXT"))
                    {
                        finalDir = localDirectoryZip;
                    } 
                    else 
                    {
                        finalDir = localDirectory;
                    }


                    if (File.Exists(finalDir  + file.Name))
                    {
                        Console.WriteLine("File " + file.Name + " Exists");
                    }else{
                        Console.WriteLine("Downloading file: " + file.Name);
                          using (Stream file1 = File.OpenWrite(finalDir + remoteFileName))
                    {
                        sftp.DownloadFile(remoteDirectory + remoteFileName, file1);
                    }
                    }
                }
            }



            Console.ReadLine();

        }

I think this is what you are looking for

 <asp:TextBox ID="txbPass" runat="server" TextMode="Password"></asp:TextBox>

The way I always do this is like this:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace example_string_to_int
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string a = textBox1.Text;
            // This turns the text in text box 1 into a string
            int b;
            if (!int.TryParse(a, out b))
            {
                MessageBox.Show("This is not a number");
            }
            else
            {
                textBox2.Text = a+" is a number" ;
            }
            // Then this 'if' statement says if the string is not a number, display an error, else now you will have an integer.
        }
    }
}

This is how I would do it.

This is how I do it with jQuery. I have a class for each link that I want to be opened in new window.

$(function(){

    $(".external").click(function(e) {
        e.preventDefault();
        window.open(this.href);
    });
});

It is often preferable to avoid loops and use vectorized functions. If that is not possible there are two approaches:

1. Preallocate your data.frame. This is not recommended because indexing is slow for data.frames.
2. Use another data structure in the loop and transform into a data.frame afterwards. A list is very useful here.

Example to illustrate the general approach:

mylist <- list() #create an empty list

for (i in 1:5) {
  vec <- numeric(5) #preallocate a numeric vector
  for (j in 1:5) { #fill the vector
    vec[j] <- i^j 
  }
  mylist[[i]] <- vec #put all vectors in the list
}
df <- do.call("rbind",mylist) #combine all vectors into a matrix

In this example it is not necessary to use a list, you could preallocate a matrix. However, if you do not know how many iterations your loop will need, you should use a list.

Finally here is a vectorized alternative to the example loop:

outer(1:5,1:5,function(i,j) i^j)

As you see it's simpler and also more efficient.

In case anyone still looking for a solution. This worked for me.

Python adds the folder containing the script you launch to the PYTHONPATH, so if you run

python application/app2/some_folder/some_file.py

Only the folder application/app2/some_folder is added to the path (not the base dir that you're executing the command in). Instead, run your file as a module and add a __init__.py in your some_folder directory.

python -m application.app2.some_folder.some_file

This will add the base dir to the python path, and then classes will be accessible via a non-relative import.

Explanation: When you install a new laravel project on your folder(for example myfolder) using the composer, it installs the complete laravel project inside your folder(myfolder/laravel) than artisan is inside laravel.that's, why you see an error,

Could not open input file: artisan

Solution: You have to go inside by command prompt to that location or move laravel files inside your folder.

UPDATE: Turned my solution into a stand-alone python script.

This solution has saved me more than once. Hopefully others find it useful. This python script will find any jupyter kernel using more than cpu_threshold CPU and prompts the user to send a SIGINT to the kernel (KeyboardInterrupt). It will keep sending SIGINT until the kernel's cpu usage goes below cpu_threshold. If there are multiple misbehaving kernels it will prompt the user to interrupt each of them (ordered by highest CPU usage to lowest). A big thanks goes to gcbeltramini for writing code to find the name of a jupyter kernel using the jupyter api. This script was tested on MACOS with python3 and requires jupyter notebook, requests, json and psutil.

Put the script in your home directory and then usage looks like:

python ~/interrupt_bad_kernels.py
Interrupt kernel chews cpu.ipynb; PID: 57588; CPU: 2.3%? (y/n) y

Script code below:

        try:
            p = psutil.Process(pid)
            cmd = p.cmdline()

Because you didn't tell the linker about location of math library. Compile with gcc test.c -o test -lm

I realize this is an older post, but thought this might be helpful to anyone wondering the same question:

While the previous answers are no doubt valid, there is a more simple reason for the distinction between textarea and input.

As mentioned previously, HTML is used to describe and give as much semantic structure to web content as possible, including input forms. A textarea may be used for input, however a textarea can also be marked as read only via the readonly attribute. The existence of such an attribute would not make any sense for an input type, and thus the distinction.

Using ajax reset() method you can clear the form after submit

example from your script above:

const form = document.getElementById(cform).reset();

Short answer: you can't. Use MSIEXEC /x

Long answer: When you run the MSI file directly at the command line, all that's happening is that it runs MSIEXEC for you. This association is stored in the registry. You can see a list of associations by (in Windows Explorer) going to Tools / Folder Options / File Types.

For example, you can run a .DOC file from the command line, and WordPad or WinWord will open it for you.

If you look in the registry under HKEY_CLASSES_ROOT\.msi, you'll see that .MSI files are associated with the ProgID "Msi.Package". If you look in HKEY_CLASSES_ROOT\Msi.Package\shell\Open\command, you'll see the command line that Windows actually uses when you "run" a .MSI file.

SQL Developer Version 4.1.0.19

Step 1: Go to Tools -> Preferences

Step 2: Select Database -> NLS

Step 3: Go to Date Format and Enter DD-MON-RR HH24: MI: SS

Step 4: Click OK.

dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))

na.omit(dat)
  x1  x2
1  1 100
3  3 300
5  5 500

I wasn't able to follow any of the above advice.

I watched multiple tutorials and found this one the most beneficial:

I added the following code to set the new height inside the "viewDidLoad" method, which worked in my app.

UIPickerView *picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 120.0)]; 
[self.view addSubview:picker];
picker.delegate = self;
picker.dataSource = self;

Hope this was helpful!

I had a similar problem while using Spring boot. With Spring boot 1.5.1.RELEASE all I had to do is to add dependency:

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
</dependency>

I thought this might be useful when using bootstrap and some glypicons:

<a class="btn btn-primary" 
    href="<%: Url.Action("Download File", "Download", 
    new { id = msg.Id, distributorId = msg.DistributorId }) %>">
    Download
    <span class="glyphicon glyphicon-paperclip"></span>
</a>

This will show an A tag, with a link to a controller, with a nice paperclip icon on it to represent a download link, and the html output is kept clean

Isn't it this simple?

var result = _(data)
            .groupBy(x => x.color)
            .map((value, key) => ({color: key, users: value}))
            .value();

Use the function Contains from the strings package.

import (
    "strings"
)
strings.Contains("something", "some") // true

That would be:

b.rstrip('\n')

If you want to strip space from each and every line, you might consider instead:

a.read().splitlines()

This will give you a list of lines, without the line end characters.

use ack its simple. just type ack <string to be searched>

If you are really, really obsessed with speed (and not so much with portability) I think the absolute fastest way to do this would be to use SIMD vector intrinsics. e.g. on Intel CPUs, you could use these SSE2 instructions:

__m128i _mm_setzero_si128 ();                   // Create a quadword with a value of 0.
void _mm_storeu_si128 (__m128i *p, __m128i a);  // Write a quadword to the specified address.

Each store instruction will set four 32-bit ints to zero in one hit.

p must be 16-byte aligned, but this restriction is also good for speed because it will help the cache. The other restriction is that p must point to an allocation size that is a multiple of 16-bytes, but this is cool too because it allows us to unroll the loop easily.

Have this in a loop, and unroll the loop a few times, and you will have a crazy fast initialiser:

// Assumes int is 32-bits.
const int mr = roundUpToNearestMultiple(m, 4);      // This isn't the optimal modification of m and n, but done this way here for clarity.    
const int nr = roundUpToNearestMultiple(n, 4);    

int i = 0;
int array[mr][nr] __attribute__ ((aligned (16)));   // GCC directive.
__m128i* px = (__m128i*)array;
const int incr = s >> 2;                            // Unroll it 4 times.
const __m128i zero128 = _mm_setzero_si128();

for(i = 0; i < s; i += incr)
{
    _mm_storeu_si128(px++, zero128);
    _mm_storeu_si128(px++, zero128);
    _mm_storeu_si128(px++, zero128);
    _mm_storeu_si128(px++, zero128);
}

There is also a variant of _mm_storeu that bypasses the cache (i.e. zeroing the array won't pollute the cache) which could give you some secondary performance benefits in some circumstances.

See here for SSE2 reference: http://msdn.microsoft.com/en-us/library/kcwz153a(v=vs.80).aspx

if (isset($_POST['remove'])) {
    $key=array_search($_GET['name'],$_SESSION['name']);
    if($key!==false)
    unset($_SESSION['name'][$key]);
    $_SESSION["name"] = array_values($_SESSION["name"]);
} 

Since $_SESSION['name'] is an array, you need to find the array key that points at the name value you're interested in. The last line rearranges the index of the array for the next use.

B is not statistically significant. The data is not capable of drawing inferences from it. C does influence B probabilities

If you just need to search for one string within another, use the index function (or rindex if you want to start scanning from the end of the string):

if (index($string, $substring) != -1) {
   print "'$string' contains '$substring'\n";
}

To search a string for a pattern match, use the match operator m//:

if ($string =~ m/pattern/) {
    print "'$string' matches the pattern\n";       
}

Greybox cannot handle forms inside it on its own. It requires a forms plugin. No iframes or external html files needed. Don't forget to download the greybox.css file too as the page misses that bit out.

I had a lot of problems with the complete load of a image and the EventListener.

Whatever I tried, the results was not reliable.

But then I found the solution. It is technically not a nice one, but now I never had a failed image load.

What I did:

                    document.getElementById(currentImgID).addEventListener("load", loadListener1);
                    document.getElementById(currentImgID).addEventListener("load", loadListener2);

                function loadListener1()
                    {
                    // Load again
                    }

                function loadListener2()
                {
                    var btn = document.getElementById("addForm_WithImage"); btn.disabled = false;
                    alert("Image loaded");
                }

Instead of loading the image one time, I just load it a second time direct after the first time and both run trough the eventhandler.

All my headaches are gone!

By the way: You guys from stackoverflow helped me already more then hundred times. For this a very big Thank you!

If you don't have the fortune of the log4j-1.2.jar on your classpath as Renko points out in his comment, you will only see the message no log4j2 configuration file found.

This is a problem if there is an error in your configuration file, as you will not be told where the problem lies upon start-up.

For instance if you have a log4j2.yaml file which log4j2 fails to process, because for example, you have not configured a YAML parser for your project, or your config is simply incorrect. You will encounter the no log4j2 configuration file found message, with no further information. This is the case even if you have a valid log4j2.xml file, as log4j2 will only attempt to process the first configuration file it finds.

I've found the best way to debug the problem is to explicitly state the configuration file you wish to use as per the command line argument mentioned above.

-Dlog4j.configurationFile=

Hopefully this will help you pinpoint if the issue is actually caused by your classloader not finding the log4j2 configuration file or something else in your configuration.

Update

You can also use the below property to change the default level of the status logger to get further information:

-Dorg.apache.logging.log4j.simplelog.StatusLogger.level=<level>

I suggest you use LinearLayout's weightSum attribute.

Adding the tag android:weightSum="3" to your LinearLayout's xml declaration and then android:layout_weight="1" to your Buttons will result in the 3 buttons being evenly distributed.

define "display it dynamically" ? that implies the table is being built via javascript and some sort of Ajax-y update .. if you just want to build the table using PHP that's really not what I would call 'dynamic'

The problem is that you are not specifying the name of the remote: Instead of

git remote add https://github.com/username/project.git

you should use:

git remote add origin https://github.com/username/project.git

GET parameters are cached by the web browser, POST is not. So with a POST you don't have to worry about caching, so that is why it is usually prefered.

Here is my Extension method. It's very efficient and it's lazy.

Usage:

var checkBoxes = tableLayoutPanel1.FindChildControlsOfType<CheckBox>();

foreach (var checkBox in checkBoxes)
{
    checkBox.Checked = false;
}

The code is:

public static IEnumerable<TControl> FindChildControlsOfType<TControl>(this Control control) where TControl : Control
    {
        foreach (var childControl in control.Controls.Cast<Control>())
        {
            if (childControl.GetType() == typeof(TControl))
            {
                yield return (TControl)childControl;
            }
            else
            {
                foreach (var next in FindChildControlsOfType<TControl>(childControl))
                {
                    yield return next;
                }
            }
        }
    }

You can achieve that using DATE_FORMAT() (click the link for more other formats)

SELECT DATE_FORMAT(colName, '%Y-%m-%d') DATEONLY, 
       DATE_FORMAT(colName,'%H:%i:%s') TIMEONLY

Here's a small piece of code that I wrote, it resizes the image to fit the container while keeping the image's original aspect ratio. It takes in as parameters the container's width, height and the image. You can modify it to fit your needs. It's simple and works fine for my applications.

private Image scaleimage(int wid, int hei, BufferedImage img){
    Image im = img;
    double scale;
    double imw = img.getWidth();
    double imh = img.getHeight();
    if (wid > imw && hei > imh){
        im = img;
    }else if(wid/imw < hei/imh){
        scale = wid/imw;
        im = img.getScaledInstance((int) (scale*imw), (int) (scale*imh), Image.SCALE_SMOOTH);
    }else if (wid/imw > hei/imh){
        scale = hei/imh;
        im = img.getScaledInstance((int) (scale*imw), (int) (scale*imh), Image.SCALE_SMOOTH);
    }else if (wid/imw == hei/imh){
        scale = wid/imw;
        im = img.getScaledInstance((int) (scale*imw), (int) (scale*imh), Image.SCALE_SMOOTH);
    } 
    return im;
}

This post is for Sublime 3.

I just installed Sublime 3, the 64 bit version, on Ubuntu 14.04. I can't tell the difference between this version and Sublime 2 as far as user interface. The reason I didn't go with Sublime 2 is that it gives an annoying "GLib critical" error messages.

Anyways - previous posts mentioned the file /sublime_text_3/Packages/Color\ Scheme\ -\ Default.sublime-package

I wanted to give two tips here with respect to this file in Sublime 3:

1. You can edit it with pico and use ^W to search the theme name. The first search result will bring you to an XML style entry where you can change the values. Make a copy before you experiment.
2. If you choose the theme in the sublime menu (under Preferences/Color Scheme) before you change this file, then the changes will be cached and your change will not take effect. So delete the cached version and restart sublime for the changes to take effect. The cached version is at ~/.config/sublime-text-3/Cache/Color Scheme - Default/

in SWIFT 5.2

you can use underneath code:

import UIKit

extension UIWindow {
    static func getTopViewController() -> UIViewController? {
        if #available(iOS 13, *){
            let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
            
            if var topController = keyWindow?.rootViewController {
                while let presentedViewController = topController.presentedViewController {
                    topController = presentedViewController
                }
                return topController
            }
        } else {
            if var topController = UIApplication.shared.keyWindow?.rootViewController {
                while let presentedViewController = topController.presentedViewController {
                    topController = presentedViewController
                }
                return topController
            }
        }
        return nil
    }
}

Here is a shorter version of the function presented above:

function getWidth() {
    if (self.innerWidth) {
       return self.innerWidth;
    }
    else if (document.documentElement && document.documentElement.clientHeight){
        return document.documentElement.clientWidth;
    }
    else if (document.body) {
        return document.body.clientWidth;
    }
    return 0;
}

If you are using pl/sql then the following code should work :

set server output on -- to retrieve and display a buffer

DECLARE

    v_text VARCHAR2(10); -- declare
BEGIN

    v_text := 'Hello';  --assign
    dbms_output.Put_line(v_text); --display
END; 

/

-- this must be use to execute pl/sql script

This is a common function of Adorners in WPF. Adorners typically appear above all other controls, but the other answers that mention z-order may fit your case better.

Alternatively, if you can customize your server response, you could return a 403 Forbidden.

The browser will not open the authentication popup and the jquery callback will be called.

You could just loop the rows and read the same cell from each row (doesn't this comprise a column?).

IBM has some more documentation on how to use this. Briefly, you're using the pointer as an offset into the class. You can't use these pointers apart from the class they refer to, so:

  int Car::*pSpeed = &Car::speed;
  Car mycar;
  mycar.*pSpeed = 65;

It seems a little obscure, but one possible application is if you're trying to write code for deserializing generic data into many different object types, and your code needs to handle object types that it knows absolutely nothing about (for example, your code is in a library, and the objects into which you deserialize were created by a user of your library). The member pointers give you a generic, semi-legible way of referring to the individual data member offsets, without having to resort to typeless void * tricks the way you might for C structs.

in your app dashboard check status to on

select sum([rows])
from sys.partitions
where object_id=object_id('tablename')
 and index_id in (0,1)

is very fast but very rarely inaccurate.

In CSS3 you have:

:nth-last-child(2)

See: https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-last-child

nth-last-child Browser Support:

• Chrome 2
• Firefox 3.5
• Opera 9.5, 10
• Safari 3.1, 4
• Internet Explorer 9

Try this : Using this you can select date by last 30 days,

SELECT DATEADD(DAY,-30,GETDATE())

Goto App.config

Find

<setting name="RunAsWindowsService" serializeAs="String">
    <value>True</value>
  </setting>

Set to False

None of these answers worked for me. This is how I did it.

the best place to change the size of the calendar is in the file jquery-ui.css

Manual cleanup:

You can KILL the processid.

mysql> show full processlist;
+---------+------------+-------------------+------+---------+-------+-------+-----------------------+
| Id      | User       | Host              | db   | Command | Time  | State | Info                  |

+---------+------------+-------------------+------+---------+-------+-------+-----------------------+

mysql> kill 1193777;

But:

• the php application might report errors (or the webserver, check the error logs)
• don't fix what is not broken - if you're not short on connections, just leave them be.

Automatic cleaner service ;)

Or you configure your mysql-server by setting a shorter timeout on wait_timeout and interactive_timeout

mysql> show variables like "%timeout%";
+--------------------------+-------+
| Variable_name            | Value |
+--------------------------+-------+
| connect_timeout          | 5     |
| delayed_insert_timeout   | 300   |
| innodb_lock_wait_timeout | 50    |
| interactive_timeout      | 28800 |
| net_read_timeout         | 30    |
| net_write_timeout        | 60    |
| slave_net_timeout        | 3600  |
| table_lock_wait_timeout  | 50    |
| wait_timeout             | 28800 |
+--------------------------+-------+
9 rows in set (0.00 sec)

Set with:

set global wait_timeout=3;
set global interactive_timeout=3;

(and also set in your configuration file, for when your server restarts)

But you're treating the symptoms instead of the underlying cause - why are the connections open? If the PHP script finished, shouldn't they close? Make sure your webserver is not using connection pooling...
