Old question, but there's an easier way.

sns.pointplot(x=x_col,y=y_col,data=df_1,color='blue')
sns.pointplot(x=x_col,y=y_col,data=df_2,color='green')
sns.pointplot(x=x_col,y=y_col,data=df_3,color='red')
plt.legend(labels=['legendEntry1', 'legendEntry2', 'legendEntry3'])

This lets you add the plots sequentially, and not have to worry about any of the matplotlib crap besides defining the legend items.

For anyone on a Mac who has Docker Desktop installed. I was able to just click the tray icon and say Restart Docker. Once it restarted was able to delete the containers.

This answers what the OP should have asked, i.e. traverse a list comparing consecutive elements (excellent SilentGhost answer), yet generalized for any group (n-gram): 2, 3, ... n:

zip(*(l[start:] for start in range(0, n)))

Examples:

l = range(0, 4)  # [0, 1, 2, 3]

list(zip(*(l[start:] for start in range(0, 2)))) # == [(0, 1), (1, 2), (2, 3)]
list(zip(*(l[start:] for start in range(0, 3)))) # == [(0, 1, 2), (1, 2, 3)]
list(zip(*(l[start:] for start in range(0, 4)))) # == [(0, 1, 2, 3)]
list(zip(*(l[start:] for start in range(0, 5)))) # == []

Explanations:

• l[start:] generates a a list/generator starting from index start
• *list or *generator: passes all elements to the enclosing function zip as if it was written zip(elem1, elem2, ...)

Note:

AFAIK, this code is as lazy as it can be. Not tested.

Not in C#. In native code you might be able to use the triple-XOR swap trick, but not in a high level type-safe language. (Anyway, I've heard that the XOR trick actually ends up being slower than using a temporary variable in many common CPU architectures.)

You should just use a temporary variable. There's no reason you can't use one; it's not like there's a limited supply.

I was facing same issue not able to post form without ajax. but found solution , hope it can help and someones time.

<form name="paymentitrform" id="paymentitrform" class="payment"
                    method="post"
                    action="abc.php">
          <input name="email" value="" placeholder="email" />
          <input type="hidden" name="planamount" id="planamount" value="0">
                                <input type="submit" onclick="form_submit() " value="Continue Payment" class="action"
                                    name="planform">

                </form>

You can submit post form, from bootstrap modal using below javascript/jquery code : call the below function onclick of input submit button

    function form_submit() {
        document.getElementById("paymentitrform").submit();
   }  

Try this code.

public void send (String fileName) {
    String SFTPHOST = "host:IP";
    int SFTPPORT = 22;
    String SFTPUSER = "username";
    String SFTPPASS = "password";
    String SFTPWORKINGDIR = "file/to/transfer";

    Session session = null;
    Channel channel = null;
    ChannelSftp channelSftp = null;
    System.out.println("preparing the host information for sftp.");

    try {
        JSch jsch = new JSch();
        session = jsch.getSession(SFTPUSER, SFTPHOST, SFTPPORT);
        session.setPassword(SFTPPASS);
        java.util.Properties config = new java.util.Properties();
        config.put("StrictHostKeyChecking", "no");
        session.setConfig(config);
        session.connect();
        System.out.println("Host connected.");
        channel = session.openChannel("sftp");
        channel.connect();
        System.out.println("sftp channel opened and connected.");
        channelSftp = (ChannelSftp) channel;
        channelSftp.cd(SFTPWORKINGDIR);
        File f = new File(fileName);
        channelSftp.put(new FileInputStream(f), f.getName());
        log.info("File transfered successfully to host.");
    } catch (Exception ex) {
        System.out.println("Exception found while tranfer the response.");
    } finally {
        channelSftp.exit();
        System.out.println("sftp Channel exited.");
        channel.disconnect();
        System.out.println("Channel disconnected.");
        session.disconnect();
        System.out.println("Host Session disconnected.");
    }
}   

I found this works:

window = Tk()
window.title('Window')

Maybe this helps?

Dart http's implementation process the bytes thanks to that "charset=utf-8", so i'm sure several implementations out there supports this, to avoid the "latin-1" fallback charset when reading the bytes from the response. In my case, I totally lose format on the response body string, so I have to do the bytes encoding manually to utf8, or add that header "inner" parameter on my server's API response.

From a Java Game Engine:

/**
 * Converts a given Image into a BufferedImage
 *
 * @param img The Image to be converted
 * @return The converted BufferedImage
 */
public static BufferedImage toBufferedImage(Image img)
{
    if (img instanceof BufferedImage)
    {
        return (BufferedImage) img;
    }

    // Create a buffered image with transparency
    BufferedImage bimage = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB);

    // Draw the image on to the buffered image
    Graphics2D bGr = bimage.createGraphics();
    bGr.drawImage(img, 0, 0, null);
    bGr.dispose();

    // Return the buffered image
    return bimage;
}

For AWS users who work with Amazon SES in conjunction with PHPMailer, this error also appears when your "from" mail sender isn't a verified sender.

To add a verified sender:

1. Log in to your Amazon AWS console: https://console.aws.amazon.com

2. Select "Amazon SES" from your list of available AWS applications

3. Select, under "Verified Senders", the "Email Addresses" --> "Verify a new email address"

4. Navigate to that new sender's email, click the confirmation e-mail's link.

And you're all set.

according to what I understood from here:

when you use align-item or justify-item, you are adjusting "the content inside a grid item along the column axis or row axis respectively.

But: if you use align-content or justify-content, you are setting the position a grid along the column axis or the row axis. it occurs when you have a grid in a bigger container and width or height are inflexible (using px).

Here's a way I do it.

With a conditional:

<Label
    {...{
      text: label,
      type,
      ...(tooltip && { tooltip }),
      isRequired: required
    }}
/>

I still prefer using the regular way of passing props down, because it is more readable (in my opinion) in the case of not have any conditionals.

Without a conditional:

<Label text={label} type={type} tooltip={tooltip} isRequired={required} />

Use the collapse argument to paste:

paste(a,collapse=" ")
[1] "aa bb cc"

Here:

df = df.reset_index()
df.columns[0] = 'New_ID'
df['New_ID'] = df.index + 880

export my store variable

export const store = createStore(rootReducer, applyMiddleware(ReduxThunk));

in action file or your file need them import this (store)

import {store} from "./path...";

this step get sate from store variable with function

const state = store.getState();

and get all of state your app

I tested the performance difference between x*x*... vs pow(x,i) for small i using this code:

#include <cstdlib>
#include <cmath>
#include <boost/date_time/posix_time/posix_time.hpp>

inline boost::posix_time::ptime now()
{
    return boost::posix_time::microsec_clock::local_time();
}

#define TEST(num, expression) \
double test##num(double b, long loops) \
{ \
    double x = 0.0; \
\
    boost::posix_time::ptime startTime = now(); \
    for (long i=0; i<loops; ++i) \
    { \
        x += expression; \
        x += expression; \
        x += expression; \
        x += expression; \
        x += expression; \
        x += expression; \
        x += expression; \

        x += expression; \
        x += expression; \
    } \
    boost::posix_time::time_duration elapsed = now() - startTime; \
\
    std::cout << elapsed << " "; \

    for (long i=0; i<loops; ++i)
    {
        x += std::pow(base, exponent);
        x += std::pow(base, exponent);
        x += std::pow(base, exponent);
        x += std::pow(base, exponent);
        x += std::pow(base, exponent);
        x += std::pow(base, exponent);
        x += std::pow(base, exponent);
        x += std::pow(base, exponent);
        x += std::pow(base, exponent);
        x += std::pow(base, exponent);
    }
    boost::posix_time::time_duration elapsed = now() - startTime;

    std::cout << elapsed << " ";

    return x;
}

int main()
{
    using std::cout;
    long loops = 100000000l;
    double x = 0.0;
    cout << "1 ";
    x += testpow<1>(rand(), loops);
    x += test1(rand(), loops);

    cout << "\n2 ";
    x += testpow<2>(rand(), loops);
    x += test2(rand(), loops);

    cout << "\n3 ";
    x += testpow<3>(rand(), loops);
    x += test3(rand(), loops);

    cout << "\n4 ";
    x += testpow<4>(rand(), loops);
    x += test4(rand(), loops);

    cout << "\n5 ";
    x += testpow<5>(rand(), loops);
    x += test5(rand(), loops);
    cout << "\n" << x << "\n";
}

Results are:

1 00:00:01.126008 00:00:01.128338 
2 00:00:01.125832 00:00:01.127227

5 00:00:01.126570 00:00:01.125930 
2.45829e+54

Note that I accumulate the result of every pow calculation to make sure the compiler doesn't optimize it away.

If I use the std::pow(double, double) version, and loops = 1000000l, I get:

1 00:00:00.011339 00:00:00.011262

This is on an Intel Core Duo running Ubuntu 9.10 64bit. Compiled using gcc 4.4.1 with -o2 optimization.

So in C, yes x*x*x will be faster than pow(x, 3), because there is no pow(double, int) overload. In C++, it will be the roughly same. (Assuming the methodology in my testing is correct.)

This is in response to the comment made by An Markm:

Even if a using namespace std directive was issued, if the second parameter to pow is an int, then the std::pow(double, int) overload from <cmath> will be called instead of ::pow(double, double) from <math.h>.

This test code confirms that behavior:

#include <iostream>

namespace foo
{

    double bar(double x, int i)
    {
        std::cout << "foo::bar\n";
        return x*i;
    }


}

double bar(double x, double y)
{
    std::cout << "::bar\n";
    return x*y;
}

using namespace foo;

int main()
{
    double a = bar(1.2, 3); // Prints "foo::bar"
    std::cout << a << "\n";
    return 0;
}

Any object if it is initailised , its defeault value is null, until unless we explicitly provide a default value.

Check this: http://jsfiddle.net/h7kRt/1/,

you should change in jsfiddle on top-left to No-wrap in <head>

Your code looks good and it will work inside a normal page. In jsfiddle your function was being defined inside a load handler and thus is in a different scope. By changing to No-wrap you have it in the global scope and can use it as you wanted.

Maybe this was just a fluke but the one time I had this error, I simply had to kill all javaw.exe processes that were running in the background. The executable JAR worked after that.

Update August 2020

As mentioned originally in this answer by SoBeRich, and in my own answer, as of git 2.4.x

git push --atomic origin <branch name> <tag>

(Note: this actually work with HTTPS only with Git 2.24)

Update May 2015

As of git 2.4.1, you can do

git config --global push.followTags true

If set to true enable --follow-tags option by default.
You may override this configuration at time of push by specifying --no-follow-tags.

As noted in this thread by Matt Rogers answering Wes Hurd:

--follow-tags only pushes annotated tags.

git tag -a -m "I'm an annotation" <tagname>

That would be pushed (as opposed to git tag <tagname>, a lightweight tag, which would not be pushed, as I mentioned here)

Update April 2013

Since git 1.8.3 (April 22d, 2013), you no longer have to do 2 commands to push branches, and then to push tags:

The new "--follow-tags" option tells "git push" to push relevant annotated tags when pushing branches out.

You can now try, when pushing new commits:

git push --follow-tags

That won't push all the local tags though, only the one referenced by commits which are pushed with the git push.

Git 2.4.1+ (Q2 2015) will introduce the option push.followTags: see "How to make “git push” include tags within a branch?".

Original answer, September 2010

The nuclear option would be git push --mirror, which will push all refs under refs/.

You can also push just one tag with your current branch commit:

git push origin : v1.0.0 

You can combine the --tags option with a refspec like:

git push origin --tags :

(since --tags means: All refs under refs/tags are pushed, in addition to refspecs explicitly listed on the command line)

You also have this entry "Pushing branches and tags with a single "git push" invocation"

A handy tip was just posted to the Git mailing list by Zoltán Füzesi:

I use .git/config to solve this:

[remote "origin"]
    url = ...
    fetch = +refs/heads/*:refs/remotes/origin/*
    push = +refs/heads/*
    push = +refs/tags/*

With these lines added git push origin will upload all your branches and tags. If you want to upload only some of them, you can enumerate them.

Haven't tried it myself yet, but it looks like it might be useful until some other way of pushing branches and tags at the same time is added to git push.
On the other hand, I don't mind typing:

$ git push && git push --tags

Beware, as commented by Aseem Kishore

push = +refs/heads/* will force-pushes all your branches.

This bit me just now, so FYI.

René Scheibe adds this interesting comment:

The --follow-tags parameter is misleading as only tags under .git/refs/tags are considered.
If git gc is run, tags are moved from .git/refs/tags to .git/packed-refs. Afterwards git push --follow-tags ... does not work as expected anymore.

I looked around the internet for correct dimensions for these densities for square images, but couldn't find anything reliable.

If it's any consolation, referring to Veerababu Medisetti's answer I used these dimensions for SQUARES :)

xxxhdpi: 1280x1280 px
xxhdpi: 960x960 px
xhdpi: 640x640 px
hdpi: 480x480 px
mdpi: 320x320 px
ldpi: 240x240 px

Firstly add a div with id.

<div id="my_map_add" style="width:100%;height:300px;"></div>

<script type="text/javascript">
function my_map_add() {
var myMapCenter = new google.maps.LatLng(28.5383866, 77.34916609);
var myMapProp = {center:myMapCenter, zoom:12, scrollwheel:false, draggable:false, mapTypeId:google.maps.MapTypeId.ROADMAP};
var map = new google.maps.Map(document.getElementById("my_map_add"),myMapProp);
var marker = new google.maps.Marker({position:myMapCenter});
marker.setMap(map);
}
</script>

<script src="https://maps.googleapis.com/maps/api/js?key=your_key&callback=my_map_add"></script>

Somewhere, you need to tell Apache that people are allowed to see contents of this directory.

<Directory "F:/bar/public">
    Order Allow,Deny
    Allow from All
    # Any other directory-specific stuff
</Directory>

There are a few different approaches here: UIAnimations to my recollection it sounds like your challenge.

Edit: too lazy of me:)

In the post, I was referring to this method:

[newView setFrame:CGRectMake( 0.0f, 480.0f, 320.0f, 480.0f)]; //notice this is OFF screen!
[UIView beginAnimations:@"animateTableView" context:nil];
[UIView setAnimationDuration:0.4];
[newView setFrame:CGRectMake( 0.0f, 0.0f, 320.0f, 480.0f)]; //notice this is ON screen!
[UIView commitAnimations];

But instead of animation the frame, you animate the alpha:

[newView setAlpha:0.0]; // set it to zero so it is all gone.
[UIView beginAnimations:@"animateTableView" context:nil];
[UIView setAnimationDuration:0.4];
[newView setAlpha:0.5]; //this will change the newView alpha from its previous zero value to 0.5f
[UIView commitAnimations];

strange issue that i solved by comment this line

Cents? If you're calculationg money values you really shouldn't use float values. Money is actually countable values. The cents or pennys etc. could be considered the two (or whatever) least significant digits of an integer. You could store, and calculate money values as integers and divide by 100 (e.g. place dot or comma two before the two last digits). Using float's can lead to strange rounding errors...

Anyway, if your epsilon is supposed to define the accuracy, it looks a bit too small (too accurate)...

Generally, as long as your log4j.properties file is on the classpath, Log4j should just automatically pick it up at JVM startup.

I also have one decision for this case with Bootstrap 3.3.5:

<div class="col-sm-5">
    <label for="date">
       <input type="date" placeholder="Date" id="date" class="form-control">         
    </label>
    <i class="glyphicon glyphicon-calendar col-sm-pull-2"></i>
</div>

On input I have something like this:

See How to create and apply a patch with Git. (From the wording of your question, I assumed that this other repository is for an entirely different codebase. If it's a repository for the same code base, you should add it as a remote as suggested by @CharlesB. Even if it is for another code base, I guess you could still add it as a remote, but you might not want to get the entire branch into your repository...)

Because of the recursive nature of JSON (nested {...}-s), regex is not suited to validate it. Sure, some regex flavours can recursively match patterns^* (and can therefor match JSON), but the resulting patterns are horrible to look at, and should never ever be used in production code IMO!

^* Beware though, many regex implementations do not support recursive patterns. Of the popular programming languages, these support recursive patterns: Perl, .NET, PHP and Ruby 1.9.2

(This is my third answer because I misunderstood what your code was doing in my original, and then made a small but crucial mistake in my second—hopefully three's a charm.

Edits: Since this seems to be a popular answer, I've made a few modifications to improve its implementation over the years—most not too major. This is so if folks use it as template, it will provide an even better basis.

As others have pointed out, your MemoryError problem is most likely because you're attempting to read the entire contents of huge files into memory and then, on top of that, effectively doubling the amount of memory needed by creating a list of lists of the string values from each line.

Python's memory limits are determined by how much physical ram and virtual memory disk space your computer and operating system have available. Even if you don't use it all up and your program "works", using it may be impractical because it takes too long.

Anyway, the most obvious way to avoid that is to process each file a single line at a time, which means you have to do the processing incrementally.

To accomplish this, a list of running totals for each of the fields is kept. When that is finished, the average value of each field can be calculated by dividing the corresponding total value by the count of total lines read. Once that is done, these averages can be printed out and some written to one of the output files. I've also made a conscious effort to use very descriptive variable names to try to make it understandable.

try:
    from itertools import izip_longest
except ImportError:    # Python 3
    from itertools import zip_longest as izip_longest

GROUP_SIZE = 4
input_file_names = ["A1_B1_100000.txt", "A2_B2_100000.txt", "A1_B2_100000.txt",
                    "A2_B1_100000.txt"]
file_write = open("average_generations.txt", 'w')
mutation_average = open("mutation_average", 'w')  # left in, but nothing written

for file_name in input_file_names:
    with open(file_name, 'r') as input_file:
        print('processing file: {}'.format(file_name))

        totals = []
        for count, fields in enumerate((line.split('\t') for line in input_file), 1):
            totals = [sum(values) for values in
                        izip_longest(totals, map(float, fields), fillvalue=0)]
        averages = [total/count for total in totals]

        for print_counter, average in enumerate(averages):
            print('  {:9.4f}'.format(average))
            if print_counter % GROUP_SIZE == 0:
                file_write.write(str(average)+'\n')

file_write.write('\n')
file_write.close()
mutation_average.close()

I added the start and exit which works. Without both it was not working

Suggestion from vsmoraes worked for me:

Laravel >= 5.4

php artisan cache:clear 
chmod -R 775 storage/
composer dump-autoload

Laravel < 5.4

php artisan cache:clear 
chmod -R 775 app/storage 
composer dump-autoload

NOTE: DO NOT DO THIS ON ANY REMOTE SERVER (DEV OR PRODUCTION)

When I asked this question, this was a problem on my localhost, running in a Virtual Machine. So I thought setting up a 777 was safe enough, however, folks are right when they say you should look for a different solution. Try 775 first

Here's a different approach using CSS instead of JavaScript/AngularJS.

CSS:

.emptymsg {
  display: list-item;
}

li + .emptymsg {
  display: none;
}

Markup:

<ul>
    <li ng-repeat="item in filteredItems"> ... </li>
    <li class="emptymsg">No items found</li>
</ul>

If the list is empty, <li ng-repeat="item in filteredItems">, etc. will get commented out and will become a comment instead of a li element.

JOptionPane.showMessageDialog(btn1, "you are clicked save button","title of dialog",2);

btn1 is a JButton variable and its used in this dialog to dialog open position btn1 or textfield etc, by default use null position of the frame.next your message and next is the title of dialog. 2 numbers of alert type icon 3 is the information 1,2,3,4. Ok I hope you understand it

While @Eli is quite correct that there usually isn't much of a need to do it, it is possible. savefig takes a bbox_inches argument that can be used to selectively save only a portion of a figure to an image.

Here's a quick example:

import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np

# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')

ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')

# Save the full figure...
fig.savefig('full_figure.png')

# Save just the portion _inside_ the second axis's boundaries
extent = ax2.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)

# Pad the saved area by 10% in the x-direction and 20% in the y-direction
fig.savefig('ax2_figure_expanded.png', bbox_inches=extent.expanded(1.1, 1.2))

The full figure:

Area inside the second subplot:

Area around the second subplot padded by 10% in the x-direction and 20% in the y-direction:

If you've only got one DataView, you can sort using that instead:

table.DefaultView.Sort = "columnName asc";

Haven't tried it, but I guess you can do this with any number of DataViews, as long as you reference the right one.

According to cppreference, nullptr is a keyword that:

denotes the pointer literal. It is a prvalue of type std::nullptr_t. There exist implicit conversions from nullptr to null pointer value of any pointer type and any pointer to member type. Similar conversions exist for any null pointer constant, which includes values of type std::nullptr_t as well as the macro NULL.

So nullptr is a value of a distinct type std::nullptr_t, not int. It implicitly converts to the null pointer value of any pointer type. This magic happens under the hood for you and you don't have to worry about its implementation. NULL, however, is a macro and it is an implementation-defined null pointer constant. It's often defined like this:

#define NULL 0

i.e. an integer.

This is a subtle but important difference, which can avoid ambiguity.

For example:

int i = NULL;     //OK
int i = nullptr;  //error
int* p = NULL;    //OK
int* p = nullptr; //OK

and when you have two function overloads like this:

void func(int x);   //1)
void func(int* x);  //2)

func(NULL) calls 1) because NULL is an integer. func(nullptr) calls 2) because nullptr converts implicitly to a pointer of type int*.

Also if you see a statement like this:

auto result = findRecord( /* arguments */ );

if (result == nullptr)
{
 ...
}

and you can't easily find out what findRecord returns, you can be sure that result must be a pointer type; nullptr makes this more readable.

In a deduced context, things work a little differently. If you have a template function like this:

template<typename T>
void func(T *ptr)
{
    ...
}

and you try to call it with nullptr:

func(nullptr);

you will get a compiler error because nullptr is of type nullptr_t. You would have to either explicitly cast nullptr to a specific pointer type or provide an overload/specialization for func with nullptr_t.

• avoid ambiguity between function overloads
• enables you to do template specialization
• more secure, intuitive and expressive code, e.g. if (ptr == nullptr) instead of if (ptr == 0)

As per you question this is what you can do

HTML

<textarea id='sample'>Area adskds;das;dsald da'adslda'daladhkdslasdljads</textarea>

JS/Jquery

$(function () {
    $('#sample').attr('readonly', 'true'); // mark it as read only
    $('#sample').css('background-color' , '#DEDEDE'); // change the background color
});

or add a class in you css with the required styling

$('#sample').addClass('yourclass');

Let me know if the requirement was different

Open the project file and not the solution. The project will be converted by the Wizard, and after converted, when you build the project, a new Solution will be generated as a VS2010 one.

If you want to create a small dots, just use icon from font awesome.

A simplest fix would be:

x = input("Give starting number: ")
y = input("Give ending number: ")

x = int(x)  # parse string into an integer
y = int(y)  # parse string into an integer

for i in range(x,y):
    print(i)

input returns you a string (raw_input in Python 2). int tries to parse it into an integer. This code will throw an exception if the string doesn't contain a valid integer string, so you'd probably want to refine it a bit using try/except statements.

I experienced a similar issue on Ubuntu 14.04 LTS after a MySQL update.

I started getting error: "Fatal error: Can't open and lock privilege tables: Incorrect file format 'user'" in /var/log/mysql/error.log

MySQL could not start.

I resolved it by removing the following directory: /var/lib/mysql/mysql

sudo rm -rf /var/lib/mysql/mysql

This leaves your other DB related files in place, only removing the mysql related files.

After running these:

sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean

Then reinstalling mysql:

sudo apt-get install mysql-server

It worked perfectly.

In order to run scripts, you should write the "python test.py" command in the command prompt, and not within the python shell. also, the test.py file should be at the path you run from in the cli.

The Date constructor in JavaScript needs a string in one of the date formats supported by the parse() method.

Apparently, the format you are specifying isn't supported in IE, so you'll need to either change the PHP code, or parse the string manually in JavaScript.

The obvious solution to developers familiar to Java is to use the LinkedList class already provided in java.util. Say, however, you wanted to make your own implementation for some reason. Here is a quick example of a linked list that inserts a new link at the beginning of the list, deletes from the beginning of the list and loops through the list to print the links contained in it. Enhancements to this implementation include making it a double-linked list, adding methods to insert and delete from the middle or end, and by adding get and sort methods as well.

Note: In the example, the Link object doesn't actually contain another Link object - nextLink is actually only a reference to another link.

class Link {
    public int data1;
    public double data2;
    public Link nextLink;

    //Link constructor
    public Link(int d1, double d2) {
        data1 = d1;
        data2 = d2;
    }

    //Print Link data
    public void printLink() {
        System.out.print("{" + data1 + ", " + data2 + "} ");
    }
}

class LinkList {
    private Link first;

    //LinkList constructor
    public LinkList() {
        first = null;
    }

    //Returns true if list is empty
    public boolean isEmpty() {
        return first == null;
    }

    //Inserts a new Link at the first of the list
    public void insert(int d1, double d2) {
        Link link = new Link(d1, d2);
        link.nextLink = first;
        first = link;
    }

    //Deletes the link at the first of the list
    public Link delete() {
        Link temp = first;
        if(first == null){
         return null;
         //throw new NoSuchElementException(); // this is the better way. 
        }
        first = first.nextLink;
        return temp;
    }

    //Prints list data
    public void printList() {
        Link currentLink = first;
        System.out.print("List: ");
        while(currentLink != null) {
            currentLink.printLink();
            currentLink = currentLink.nextLink;
        }
        System.out.println("");
    }
}  

class LinkListTest {
    public static void main(String[] args) {
        LinkList list = new LinkList();

        list.insert(1, 1.01);
        list.insert(2, 2.02);
        list.insert(3, 3.03);
        list.insert(4, 4.04);
        list.insert(5, 5.05);

        list.printList();

        while(!list.isEmpty()) {
            Link deletedLink = list.delete();
            System.out.print("deleted: ");
            deletedLink.printLink();
            System.out.println("");
        }
        list.printList();
    }
}

It is possible to have hierarchical branch names (branch names with slash). For example in my repository I have such branch(es). One caveat is that you can't have both branch 'foo' and branch 'foo/bar' in repository.

Your problem is not with creating branch with slash in name.

$ git branch foo/bar
error: unable to resolve reference refs/heads/labs/feature: Not a directory
fatal: Failed to lock ref for update: Not a directory

The above error message talks about 'labs/feature' branch, not 'foo/bar' (unless it is a mistake in copy'n'paste, i.e you edited parts of session). What is the result of git branch or git rev-parse --symbolic-full-name HEAD?

To get the C# version from code, use this code from the Microsoft documentation to get the .NET Framework version and then match it up using the table that everyone else mentions. You can code up the Framework to C# version map in a dictionary or something to actually have your function return the C# version. Works if you have .NET Framework >= 4.5.

using System;
using Microsoft.Win32;

public class GetDotNetVersion
{
   public static void Main()
   {
      Get45PlusFromRegistry();
   }

   private static void Get45PlusFromRegistry()
   {
      const string subkey = @"SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\";

      using (var ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32).OpenSubKey(subkey))
      {
        if (ndpKey != null && ndpKey.GetValue("Release") != null) {
            Console.WriteLine($".NET Framework Version: {CheckFor45PlusVersion((int) ndpKey.GetValue("Release"))}");
        }
         else {
            Console.WriteLine(".NET Framework Version 4.5 or later is not detected.");
         } 
      }

      // Checking the version using >= enables forward compatibility.
      string CheckFor45PlusVersion(int releaseKey)
      {
         if (releaseKey >= 528040)
            return "4.8 or later";
         if (releaseKey >= 461808)
            return "4.7.2";
         if (releaseKey >= 461308)
            return "4.7.1";
         if (releaseKey >= 460798)
            return "4.7";
         if (releaseKey >= 394802)
            return "4.6.2";
         if (releaseKey >= 394254)
            return "4.6.1";      
         if (releaseKey >= 393295)
            return "4.6";      
         if (releaseKey >= 379893)
            return "4.5.2";      
         if (releaseKey >= 378675)
            return "4.5.1";      
         if (releaseKey >= 378389)
            return "4.5";      
         // This code should never execute. A non-null release key should mean
         // that 4.5 or later is installed.
         return "No 4.5 or later version detected";
      }
   }
}   
// This example displays output like the following:
//       .NET Framework Version: 4.6.1

I came up with this function which works for me, hope this will help somebody

$word_list = 'word1, word2, word3, word4';
$str = 'This string contains word1 in it';

function checkStringAgainstList($str, $word_list)
{
  $word_list = explode(', ', $word_list);
  $str = explode(' ', $str);

  foreach ($str as $word):
    if (in_array(strtolower($word), $word_list)) {
        return TRUE;
    }
  endforeach;

  return false;
}

Also, note that answers with strpos() will return true if the matching word is a part of other word. For example if word list contains 'st' and if your string contains 'street', strpos() will return true

In DJango 3.0 the default value of a BooleanField in model.py is set like this:

class model_name(models.Model):
example_name = models.BooleanField(default=False)

If you want to select a variable range containing all headers cells:

Dim sht as WorkSheet
Set sht = This Workbook.Sheets("Data")

'Range(Cells(1,1),Cells(1,Columns.Count).End(xlToLeft)).Select '<<< NOT ROBUST

sht.Range(sht.Cells(1,1),sht.Cells(1,Columns.Count).End(xlToLeft)).Select

...as long as there's no other content on that row.

EDIT: updated to stress that when using Range(Cells(...), Cells(...)) it's good practice to qualify both Range and Cells with a worksheet reference.

Don't call methods within the Fragment that require getActivity() until onStart in the parent Activity.

private MyFragment myFragment;


public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);

    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    myFragment = new MyFragment();

    ft.add(android.R.id.content, youtubeListFragment).commit();

    //Other init calls
    //...
}


@Override
public void onStart()
{
    super.onStart();

    //Call your Fragment functions that uses getActivity()
    myFragment.onPageSelected();
}

IIF is a non-standard T-SQL function. It was added to SQL SERVER 2012, so that Access could migrate to SQL Server without refactoring the IIF's to CASE before hand. Once the Access db is fully migrated into SQL Server, you can refactor.

ApplicationId must be of type UniqueIdentifier. Your code works fine if you do:

DECLARE @TTEST TABLE
(
  TEST UNIQUEIDENTIFIER
)

DECLARE @UNIQUEX UNIQUEIDENTIFIER
SET @UNIQUEX = NEWID();

INSERT INTO @TTEST
(TEST)
VALUES
(@UNIQUEX);

SELECT * FROM @TTEST

Therefore I would say it is safe to assume that ApplicationId is not the correct data type.

You can use Named Sections.

The API of java.io.File only supports getting the last modified time. And the Internet is very quiet on this topic as well.

Unless I missed something significant, the Java library as is (up to but not yet including Java 7) does not include this capability. So if you were desperate for this, one solution would be to write some C(++) code to call system routines and call it using JNI. Most of this work seems to be already done for you in a library called JNA, though.

You may still need to do a little OS specific coding in Java for this, though, as you'll probably not find the same system calls available in Windows and Unix/Linux/BSD/OS X.

delete acts like a non real world situation, it just removes the item, but the array length stays the same:

example from node terminal:

> var arr = ["a","b","c","d"];
> delete arr[2]
true
> arr
[ 'a', 'b', , 'd', 'e' ]

Here is a function to remove an item of an array by index, using slice(), it takes the arr as the first arg, and the index of the member you want to delete as the second argument. As you can see, it actually deletes the member of the array, and will reduce the array length by 1

function(arr,arrIndex){
    return arr.slice(0,arrIndex).concat(arr.slice(arrIndex + 1));
}

What the function above does is take all the members up to the index, and all the members after the index , and concatenates them together, and returns the result.

Here is an example using the function above as a node module, seeing the terminal will be useful:

> var arr = ["a","b","c","d"]
> arr
[ 'a', 'b', 'c', 'd' ]
> arr.length
4 
> var arrayRemoveIndex = require("./lib/array_remove_index");
> var newArray = arrayRemoveIndex(arr,arr.indexOf('c'))
> newArray
[ 'a', 'b', 'd' ] // c ya later
> newArray.length
3

please note that this will not work one array with dupes in it, because indexOf("c") will just get the first occurance, and only splice out and remove the first "c" it finds.

From the above answeres, following did not work or less preferable:

• (previous_info | json) != '{}' works only for {} empty case, not for null or undefined case
• Object.getOwnPropertyNames(previous_info).length also did not work, as Object is not accessible in the template
• I would not like to create a dedicated variable this.objectLength = Object.keys(this.previous_info).length !=0;

• I would not like to create a dedicated function

  isEmptyObject(obj) {
     return (obj && (Object.keys(obj).length === 0));
  }
  

Solution: keyvalue pipe along with ?. (safe navigation operator); and it seems simple.

It works well when previous_info = null or previous_info = undefined or previous_info = {} and treats as falsy value.

<div  *ngIf="(previous_info | keyvalue)?.length">

keyvalue - Transforms Object or Map into an array of key value pairs.

?. - The Angular safe navigation operator (?.) is a fluent and convenient way to guard against null and undefined

DEMO: demo with angular 9, though it works for previous versions as well

Of course, be mindful that your program will only be useful in english speaking countries if you detect dates this way. You might want to consider:

Set<String> dayNames = Calendar.getInstance()
 .getDisplayNames(Calendar.DAY_OF_WEEK,
      Calendar.SHORT,
      Locale.getDefault())
 .keySet();

From there you can use .startsWith or .matches or whatever other method that others have mentioned above. This way you get the default locale for the jvm. You could always pass in the locale (and maybe default it to the system locale if it's null) as well to be more robust.

For me the case was completely different. I had created a studio64.exe.vmoptions file in C:\Users\YourUserName\.AndroidStudio3.4\config. In that folder, I had a typo of extra spaces. Due to that I was getting the same error.

I did the following changes to my project/urls.py and it worked for me

Add this line : from django.conf.urls import url

and add : url(r'^media/(?P.*)$', serve, {'document_root': settings.MEDIA_ROOT, }), in urlpatterns.

In SQL Server you would generally use. I don't know about other database engines.

Hai sridhar, I found an answer for your prob

ClientScript.RegisterClientScriptBlock(GetType(), "sas", "<script> alert('Inserted successfully');</script>", true);

change false to true

or try this

ScriptManager.RegisterClientScriptBlock(ursavebuttonID, typeof(LinkButton or button), "sas", "<script> alert('Inserted successfully');</script>", true);

A popular workaround is to patch the deployment with a dummy annotation (or label):

kubectl patch deployment <name> -p \
  "{\"spec\":{\"template\":{\"metadata\":{\"annotations\":{\"date\":\"`date +'%s'`\"}}}}}"

Assuming your deployment meets these requirements, this will cause K8s to pull any new image and redeploy.

It takes two numbers from the user, feeds them to the function called add (in the very last line of the code), and add will sum them up and print them.

#!/bin/bash

read -p "Enter the first  value: " x
read -p "Enter the second value: " y

add(){
    arg1=$1 # arg1 gets to be the first  assigned argument (note there are no spaces)
      arg2=$2 # arg2 gets to be the second assigned argument (note there are no spaces)

    echo $(($arg1 + $arg2))
}

add x y # Feeding the arguments

This is documented in the 'R Installation and Administration' manual that came with your installation.

On my Linux box:

R> .libPaths()
[1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"      
[3] "/usr/lib/R/library"           
R> 

meaning that the default path is the first of these. You can override that via an argument to both install.packages() (from inside R) or R CMD INSTALL (outside R).

You can also override by setting the R_LIBS_USER variable.

This answer uses promises, a JavaScript feature of the ECMAScript 6 standard. If your target platform does not support promises, polyfill it with PromiseJs.

You can get the Deferred object jQuery creates for the animation using .promise() on the animation call. Wrapping these Deferreds into ES6 Promises results in much cleaner code than using timers.

You can also use Deferreds directly, but this is generally discouraged because they do not follow the Promises/A+ specification.

The resulting code would look like this:

var p1 = Promise.resolve($('#Content').animate({ opacity: 0.5 }, { duration: 500, queue: false }).promise());
var p2 = Promise.resolve($('#Content').animate({ marginLeft: "-100px" }, { duration: 2000, queue: false }).promise());
Promise.all([p1, p2]).then(function () {
    return $('#Content').animate({ width: 0 }, { duration: 500, queue: false }).promise();
});

Note that the function in Promise.all() returns the promise. This is where magic happens. If in a then call a promise is returned, the next then call will wait for that promise to be resolved before executing.

jQuery uses an animation queue for each element. So animations on the same element are executed synchronously. In this case you wouldn't have to use promises at all!

I have disabled the jQuery animation queue to demonstrate how it would work with promises.

Promise.all() takes an array of promises and creates a new Promise that finishes after all promises in the array finished.

Promise.race() also takes an array of promises, but finishes as soon as the first Promise finished.

Another suggestion is using flexbox instead of tables altogether. This is a "modern browser" thing of course, but come on, it's 2016 ;)

At least this might be an alternative solution for those looking for an answer to this nowadays, since the original post was from 2010.

I created UILabel subclass named ResponsiveLabel which is based on textkit API introduced in iOS 7. It uses the same approach suggested by NAlexN. It provides flexibility to specify a pattern to search in the text. One can specify styles to be applied to those patterns as well as action to be performed on tapping the patterns.

//Detects email in text

 NSString *emailRegexString = @"[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,4}";
 NSError *error;
 NSRegularExpression *regex = [[NSRegularExpression alloc]initWithPattern:emailRegexString options:0 error:&error];
 PatternDescriptor *descriptor = [[PatternDescriptor alloc]initWithRegex:regex withSearchType:PatternSearchTypeAll withPatternAttributes:@{NSForegroundColorAttributeName:[UIColor redColor]}];
 [self.customLabel enablePatternDetection:descriptor];

If you want to make a string clickable, you can do this way. This code applies attributes to each occurrence of the string "text".

PatternTapResponder tapResponder = ^(NSString *string) {
    NSLog(@"tapped = %@",string);
};

[self.customLabel enableStringDetection:@"text" withAttributes:@{NSForegroundColorAttributeName:[UIColor redColor],
                                                                 RLTapResponderAttributeName: tapResponder}];

In my case this code solved my error :

(function (window, document, $) {
            'use strict';
             var $html = $('html');
             $('input[name="myiCheck"]').on('ifClicked', function (event) {
             alert("You clicked " + this.value);
             });
})(window, document, jQuery);

You don't should put your function inside $(document).ready

You can set border properties on a tr element, but according to the CSS 2.1 specification, such properties have no effect in the separated borders model, which tends to be the default in browsers. Ref.: 17.6.1 The separated borders model. (The initial value of border-collapse is separate according to CSS 2.1, and some browsers also set it as default value for table. The net effect anyway is that you get separated border on almost all browsers unless you explicitly specifi collapse.)

Thus, you need to use collapsing borders. Example:

<style>
table { border-collapse: collapse; }
tr:nth-child(3) { border: solid thin; }
</style>

Testing ErrorLevel works for console applications, but as hinted at by dmihailescu, this won't work if you're trying to run a windowed application (e.g. Win32-based) from a command prompt. A windowed application will run in the background, and control will return immediately to the command prompt (most likely with an ErrorLevel of zero to indicate that the process was created successfully). When a windowed application eventually exits, its exit status is lost.

Instead of using the console-based C++ launcher mentioned elsewhere, though, a simpler alternative is to start a windowed application using the command prompt's START /WAIT command. This will start the windowed application, wait for it to exit, and then return control to the command prompt with the exit status of the process set in ErrorLevel.

start /wait something.exe
echo %errorlevel%

I know the answer has already been provided. But I just wanted to elaborate with regards to doing this in a Blazor app (razor)...

You will need to inject IJSRuntime, in order to perform JSInterop (running javascript functions from C#)

IN YOUR RAZOR PAGE:

@inject IJSRuntime JSRuntime

Once you have that injected, create a button with a click event that calls a C# method:

<MatFAB Icon="@MatIconNames.Print" OnClick="@(async () => await print())"></MatFAB>

(or something more simple if you don't use MatBlazor)

<button @onclick="@(async () => await print())">PRINT</button>

For the C# method:

public async Task print()
{
    await JSRuntime.InvokeVoidAsync("printDocument");
}

NOW IN YOUR index.html:

<script>
    function printDocument() {
        window.print();
    }
</script>

Something to note, the reason the onclick events are asynchronous is because IJSRuntime awaits it's calls such as InvokeVoidAsync

PS: If you wanted to message box in asp net core for instance:

await JSRuntime.InvokeAsync<string>("alert", "Hello user, this is the message box");

To have a confirm message box:

bool question = await JSRuntime.InvokeAsync<bool>("confirm", "Are you sure you want to do this?");
    if(question == true)
    {
        //user clicked yes
    }
    else
    {
        //user clicked no
    }

Hope this helps :)

This article helped me a lot in understanding the concept.

In summary,

• Both are probabilistic models, meaning they both use probability (conditional probability , to be precise) to calculate classes for the unknown data.
• The Generative Classifiers apply Joint PDF & Bayes Theorem on the data set and calculate conditional probability using values from those.
• The Discriminative Classifiers directly find Conditional probablity on the data set

Summarizing the Answers

I can see many different answers and ways to do this but there is the rub in this and that is the objective.

Yes, the objective. If you want to only know the column names you can use

SELECT * FROM my_table WHERE 1=0
or
SELECT TOP 0 * FROM my_table

But if you want to use those columns somewhere or simply say manipulate them then the quick queries above are not going to be of any use. You need to use

SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = N'Customers'

one more way to know some specific columns where we are in need of some similar columns

SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME like N'%[ColumnName]%' and TABLE_NAME = N'[TableName]'

Loki's answer points to the Hibernate 3 docs and provides good information, but I was still not getting the results I expected.

Much thrashing, waving of arms and general dead mouse runs finally landed me my cheese.

Because Hibernate 3 is using Simple Logging Facade for Java (SLF4J) (per the docs), if you are relying on Log4j 1.2 you will also need the slf4j-log4j12-1.5.10.jar if you are wanting to fully configure Hibernate logging with a log4j configuration file. Hope this helps the next guy.

after complete the code first merge branch to master then delete that branch

git checkout master
git merge <branch-name>
git branch -d <branch-name>

I had the same error when we imported a key into a keystore that was build using a 64bit OpenSSL Version. When we followed the same procedure to import the key into a keystore that was build using a 32 bit OpenSSL version everything went fine.

To add to @jarib's answer, I have made several extension methods which help eliminate the race condition.

Here is my setup:

I have a class Called "Driver.cs". It contains a static class full of extension methods for the driver and other useful static functions.

For elements I commonly need to retrieve, I create an extension method like the following:

public static IWebElement SpecificElementToGet(this IWebDriver driver) {
    return driver.FindElement(By.SomeSelector("SelectorText"));
}

This allows you to retrieve that element from any test class with the code:

driver.SpecificElementToGet();

Now, if this results in a StaleElementReferenceException, I have the following static method in my driver class:

public static void WaitForDisplayed(Func<IWebElement> getWebElement, int timeOut)
{
    for (int second = 0; ; second++)
    {
        if (second >= timeOut) Assert.Fail("timeout");
        try
        {
            if (getWebElement().Displayed) break;
        }
        catch (Exception)
        { }
        Thread.Sleep(1000);
    }
}

This function's first parameter is any function which returns an IWebElement object. The second parameter is a timeout in seconds (the code for the timeout was copied from the Selenium IDE for FireFox). The code can be used to avoid the stale element exception the following way:

MyTestDriver.WaitForDisplayed(driver.SpecificElementToGet,5);

The above code will call driver.SpecificElementToGet().Displayed until driver.SpecificElementToGet() throws no exceptions and .Displayed evaluates to true and 5 seconds have not passed. After 5 seconds, the test will fail.

On the flip side, to wait for an element to not be present, you can use the following function the same way:

public static void WaitForNotPresent(Func<IWebElement> getWebElement, int timeOut) {
    for (int second = 0;; second++) {
        if (second >= timeOut) Assert.Fail("timeout");
            try
            {
                if (!getWebElement().Displayed) break;
            }
            catch (ElementNotVisibleException) { break; }
            catch (NoSuchElementException) { break; }
            catch (StaleElementReferenceException) { break; }
            catch (Exception)
            { }
            Thread.Sleep(1000);
        }
}

The problem is that jQuery doesn't trigger the native click event for <a> elements so that navigation doesn't happen (the normal behavior of an <a>), so you need to do that manually. For almost all other scenarios, the native DOM event is triggered (at least attempted to - it's in a try/catch).

To trigger it manually, try:

var a = $("<a>")
    .attr("href", "http://i.stack.imgur.com/L8rHf.png")
    .attr("download", "img.png")
    .appendTo("body");

a[0].click();

a.remove();

Yes, I was late, but I can add for Assemble users: you can use buil-in "parseJSON" helper http://assemble.io/helpers/helpers-data.html. (Discovered in https://github.com/assemble/assemble/issues/416).

Here's a simplified version with extended explanation for beginners like me who are trying to learn how to put more than one command in one line.

If you were to write out the problem in steps, it would look like this:

// For every file in this directory
// Check the filetype
// If it's an ASCII file, then print out the filename

To achieve this, we can use three UNIX commands: find, file, and grep.

find will check every file in the directory.

file will give us the filetype. In our case, we're looking for a return of 'ASCII text'

grep will look for the keyword 'ASCII' in the output from file

So how can we string these together in a single line? There are multiple ways to do it, but I find that doing it in order of our pseudo-code makes the most sense (especially to a beginner like me).

find ./ -exec file {} ";" | grep 'ASCII'

Looks complicated, but not bad when we break it down:

find ./ = look through every file in this directory. The find command prints out the filename of any file that matches the 'expression', or whatever comes after the path, which in our case is the current directory or ./

The most important thing to understand is that everything after that first bit is going to be evaluated as either True or False. If True, the file name will get printed out. If not, then the command moves on.

-exec = this flag is an option within the find command that allows us to use the result of some other command as the search expression. It's like calling a function within a function.

file {} = the command being called inside of find. The file command returns a string that tells you the filetype of a file. Regularly, it would look like this: file mytextfile.txt. In our case, we want it to use whatever file is being looked at by the find command, so we put in the curly braces {} to act as an empty variable, or parameter. In other words, we're just asking for the system to output a string for every file in the directory.

";" = this is required by find and is the punctuation mark at the end of our -exec command. See the manual for 'find' for more explanation if you need it by running man find.

| grep 'ASCII' = | is a pipe. Pipe take the output of whatever is on the left and uses it as input to whatever is on the right. It takes the output of the find command (a string that is the filetype of a single file) and tests it to see if it contains the string 'ASCII'. If it does, it returns true.

NOW, the expression to the right of find ./ will return true when the grep command returns true. Voila.

This is what I ended up doing. I'm sure there is a more efficient way of doing this but this is what i came up with.

Model/User.php

protected $rules = [
    'email_address' => 'sometimes|required|email|unique:users,email_address, {{$id}}',
];

Model/BaseModel.php

public function validate($data, $id = null) {


      $rules = $this->$rules_string;

     //let's loop through and explode the validation rules
     foreach($rules as $keys => $value) {

        $validations = explode('|', $value);

        foreach($validations as $key=>$value) {

            // Seearch for {{$id}} and replace it with $id
            $validations[$key] = str_replace('{{$id}}', $id, $value);

        }
        //Let's create the pipe seperator 
        $implode = implode("|", $validations);
        $rules[$keys] = $implode;

     }
     ....

  }

I pass the $user_id to the validation in the controller

Controller/UserController.php

public function update($id) { 

   .....

    $user = User::find($user_id);

    if($user->validate($formRequest, $user_id)) {
      //validation succcess 
    } 

    ....


}

For those who can't (or don't want to) setup a debugger to track down the original exception which was causing the rollback-flag to get set, you can just add a bunch of debug statements throughout your code to find the lines of code which trigger the rollback-only flag:

logger.debug("Is rollbackOnly: " + TransactionAspectSupport.currentTransactionStatus().isRollbackOnly());

Adding this throughout the code allowed me to narrow down the root cause, by numbering the debug statements and looking to see where the above method goes from returning "false" to "true".

Text wrapping is not part of SVG1.1, the currently implemented spec. You should rather use HTML via the <foreignObject/> element.

<svg ...>

<switch>
<foreignObject x="20" y="90" width="150" height="200">
<p xmlns="http://www.w3.org/1999/xhtml">Text goes here</p>
</foreignObject>

<text x="20" y="20">Your SVG viewer cannot display html.</text>
</switch>

</svg>

With Java 9, we can use ProcessHandle which makes it easier to identify and control native processes:

ProcessHandle
  .allProcesses()
  .filter(p -> p.info().commandLine().map(c -> c.contains("firefox")).orElse(false))
  .findFirst()
  .ifPresent(ProcessHandle::destroy)

where "firefox" is the process to kill.

This:

• First lists all processes running on the system as a Stream<ProcessHandle>

• Lazily filters this stream to only keep processes whose launched command line contains "firefox". Both commandLine or command can be used depending on how we want to retrieve the process.

• Finds the first filtered process meeting the filtering condition.

• And if at least one process' command line contained "firefox", then kills it using destroy.

No import necessary as ProcessHandle is part of java.lang.

When you use df.apply(), each row of your DataFrame will be passed to your lambda function as a pandas Series. The frame's columns will then be the index of the series and you can access values using series[label].

So this should work:

df['D'] = (df.apply(lambda x: myfunc(x[colNames[0]], x[colNames[1]]), axis=1)) 

Here my solution without going backward and without a temporary list

while (listBox1.Items.Count > 0)
{
  string s = listBox1.Items[0] as string;
  // do something with s
  listBox1.Items.RemoveAt(0);
}

I'm astonished by the second number you mention (and confirm by your requested rounding) -- at first I thought my instinct for mental arithmetic was starting to fail me (I am getting older, after all, so that might be going the same way as my once-sharp memory!-)... but then I confirmed it hasn't, yet, by using, as I imagine you are, Python 3.1, and copying and pasting..:

>>> def input_meal():  
...     mealPrice = input('Enter the meal subtotal: $')  
...     mealPrice = float (mealPrice)  
...     return mealPrice  
... 
>>> def calc_tax(mealPrice):  
...     tax = mealPrice*.06  
...     return tax
... 
>>> m = input_meal()
Enter the meal subtotal: $34.45
>>> print(calc_tax(m))
2.067
>>> 

...as expected -- yet, you say it instead "returns a display of $ 2.607"... which might be a typo, just swapping two digits, except that you then ask "How can I set that to $2.61 instead?" so it really seems you truly mean 2.607 (which might be rounded to 2.61 in various ways) and definitely not the arithmetically correct result, 2.067 (which at best might be rounded to 2.07... definitely not to 2.61 as you request).

I imagine you first had the typo occur in transcription, and then mentally computed the desired rounding from the falsified-by-typo 2.607 rather than the actual original result -- is that what happened? It sure managed to confuse me for a while!-)

Anyway, to round a float to two decimal digits, simplest approach is the built-in function round with a second argument of 2:

>>> round(2.067, 2)
2.07
>>> round(2.607, 2)
2.61

For numbers exactly equidistant between two possibilities, it rounds-to-even:

>>> round(2.605, 2)
2.6
>>> round(2.615, 2)
2.62

or, as the docs put it (exemplifying with the single-argument form of round, which rounds to the closest integer):

if two multiples are equally close, rounding is done toward the even choice (so, for example, both round(0.5) and round(-0.5) are 0, and round(1.5) is 2).

However, for computations on money, I second the recommendation, already given in other answers, to stick with what the decimal module offers, instead of float numbers.

As declaration of array list in java is like

public class ArrayList<E> extends AbstractList<E> implements List<E>, RandomAccess, Cloneable, Serializable  

There is numerous way you can create and initialize array list in java.

 1) List list = new ArrayList();

 2) List<type> myList = new ArrayList<>();

 3) List<type> myList = new ArrayList<type>();

 4) Using Utility class

    List<Integer> list = Arrays.asList(8, 4);
    Collections.unmodifiableList(Arrays.asList("a", "b", "c"));

 5) Using static factory method

    List<Integer> immutableList = List.of(1, 2);


 6) Creation and initializing at a time

    List<String> fixedSizeList = Arrays.asList(new String[] {"Male", "Female"});



 Again you can create different types of list. All has their own characteristics

 List a = new ArrayList();
 List b = new LinkedList();
 List c = new Vector(); 
 List d = new Stack(); 
 List e = new CopyOnWriteArrayList();

From the Jquery docs: you specify the async option to be false to get a synchronous Ajax request. Then your callback can set some data before your mother function proceeds.

Here's what your code would look like if changed as suggested:

beforecreate: function(node,targetNode,type,to) {
    jQuery.ajax({
         url:    url,
         success: function(result) {
                      if(result.isOk == false)
                          alert(result.message);
                  },
         async:   false
    });          
}

this is because $.ajax is the only request type that you can set the asynchronousity for

For Eclipse Users. If you have a Run Configuration that does clean package for example.

In the Run Configuration panel there is a JRE tab where you can specify against which runtime it should run. Note that this configuration overrides whatever is in the pom.xml.

Please Following Expression

Regex regex = new Regex(@"(((0|1)[0-9]|2[0-9]|3[0-1])\/(0[1-9]|1[0-2])\/((19|20)\d\d))$");

In general, that's not how systems use GET requests. So, it will be hard to get your libraries to play along. In fact, the spec says that "If the request method is a case-sensitive match for GET or HEAD act as if data is null." So, I think you are out of luck unless the browser you are using doesn't respect that part of the spec.

You can probably setup an endpoint on your own server for a POST ajax request, then redirect that in your server code to a GET request with a body.

If you aren't absolutely tied to GET requests with the body being the data, you have two options.

POST with data: This is probably what you want. If you are passing data along, that probably means you are modifying some model or performing some action on the server. These types of actions are typically done with POST requests.

GET with query string data: You can convert your data to query string parameters and pass them along to the server that way.

java.time

Using java.time framework built into Java 8:

import java.time.LocalDate;

LocalDate now = LocalDate.now(); // 2015-11-24
LocalDate earlier = now.minusMonths(1); // 2015-10-24

earlier.getMonth(); // java.time.Month = OCTOBER
earlier.getMonth.getValue(); // 10
earlier.getYear(); // 2015

You can index Dictionary, you didn't need 'get'.

Dictionary<string,string> example = new Dictionary<string,string>();
...
example.Add("hello","world");
...
Console.Writeline(example["hello"]);

An efficient way to test/get values is TryGetValue (thanx to Earwicker):

if (otherExample.TryGetValue("key", out value))
{
    otherExample["key"] = value + 1;
}

With this method you can fast and exception-less get values (if present).

Most probably, you didn't install any SQL Server Engine service. If no SQL Server engine is installed, no service will appear in the SQL Server Configuration Manager tool. Consider that the packages SQLManagementStudio_Architecture_Language.exe and SQLEXPR_Architecture_Language.exe, available in the Microsoft site contain, respectively only the Management Studio GUI Tools and the SQL Server engine.

If you want to have a full featured SQL Server installation, with the database engine and Management Studio, download the installer file of SQL Server with Advanced Services. Moreover, to have a sample database in order to perform some local tests, use the Adventure Works database.

Considering the package of SQL Server with Advanced Services, at the beginning at the installation you should see something like this (the screenshot below is about SQL Server 2008 Express, but the feature selection is very similar). The checkbox next to "Database Engine Services" must be checked. In the next steps, you will be able to configure the instance settings and other options.

Execute again the installation process and select the database engine services in the feature selection step. At the end of the installation, you should be able to see the SQL Server services in the SQL Server Configuration Manager.

In my scenario this was happening because I renamed a parameter in swagger.yaml but did not reload the docs page.

Hence I was trying the API with an unexpected input parameter.
Long story short, F5 is my friend.

"I hoped (and still hope) that there is something like my beloved SQL*Plus for Oracle that can execute a file with all kinds of SQL Statements."

If you're looking for a simple program that can import a file and execute the SQL statements in it, take a look at DBWConsole (freeware). I have used it to process DDL scripts (table schema) as well as action queries. It does not return data sets so it's not useful for SELECT queries. It supports single line comments prefixed by -- but not multi-line comments wrapped in /* */. It supports command line parameters.

If you want an interactive UI like Oracle SQL Developer or SSMS for Access then Matthew Lock's reference to WinSQL is what you should try.

A little late to the party, found this while looking for an example of the marker click event. The undefined error the original poster got is because the onClick function is referred to before it's defined. Swap line 2 and 3 and it should work.

In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic about following the C++ standard), you can do:

int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++

If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:

int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!

Or, better yet, use a standard container:

int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>

If you still want a proper array, you can use a constant, not a variable, when creating it:

const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)

Similarly, if you want to get the size from a function in C++11, you can use a constexpr:

constexpr int n()
{
    return 10;
}

double a[n()]; // n() is a compile time constant expression

you need only set default value to parameters(you do not need the Route attribute):

public IHttpActionResult Get(string apc = null, string xpc = null, int? sku = null)
{ ... }

In SQL Server 2008 you can use

http://www.sommarskog.se/share_data.html#tableparam

or else simple and same as common execution

CREATE PROCEDURE OrderSummary @MaxQuantity INT OUTPUT AS

SELECT Ord.EmployeeID, SummSales = SUM(OrDet.UnitPrice * OrDet.Quantity)
FROM Orders AS Ord
     JOIN [Order Details] AS OrDet ON (Ord.OrderID = OrDet.OrderID)
GROUP BY Ord.EmployeeID
ORDER BY Ord.EmployeeID

SELECT @MaxQuantity = MAX(Quantity) FROM [Order Details]

RETURN (SELECT SUM(Quantity) FROM [Order Details])
GO

I hopes its help to you

REST means working with the standards of the web, and the standard for "secure" transfer on the web is SSL. Anything else is going to be kind of funky and require extra deployment effort for clients, which will have to have encryption libraries available.

Once you commit to SSL, there's really nothing fancy required for authentication in principle. You can again go with web standards and use HTTP Basic auth (username and secret token sent along with each request) as it's much simpler than an elaborate signing protocol, and still effective in the context of a secure connection. You just need to be sure the password never goes over plain text; so if the password is ever received over a plain text connection, you might even disable the password and mail the developer. You should also ensure the credentials aren't logged anywhere upon receipt, just as you wouldn't log a regular password.

HTTP Digest is a safer approach as it prevents the secret token being passed along; instead, it's a hash the server can verify on the other end. Though it may be overkill for less sensitive applications if you've taken the precautions mentioned above. After all, the user's password is already transmitted in plain-text when they log in (unless you're doing some fancy JavaScript encryption in the browser), and likewise their cookies on each request.

Note that with APIs, it's better for the client to be passing tokens - randomly generated strings - instead of the password the developer logs into the website with. So the developer should be able to log into your site and generate new tokens that can be used for API verification.

The main reason to use a token is that it can be replaced if it's compromised, whereas if the password is compromised, the owner could log into the developer's account and do anything they want with it. A further advantage of tokens is you can issue multiple tokens to the same developers. Perhaps because they have multiple apps or because they want tokens with different access levels.

(Updated to cover implications of making the connection SSL-only.)

Are you tied to this library? Google Gson is very popular. I have myself not used it with Generics but their front page says Gson considers support for Generics very important.

This can be done using REGEXP_SUBSTR easily.

Please use

REGEXP_SUBSTR('STRING_EXAMPLE','[^_]+',1,1) 

where STRING_EXAMPLE is your string.

Try:

SELECT 
REGEXP_SUBSTR('STRING_EXAMPLE','[^_]+',1,1) 
from dual

It will solve your problem.

Ideone supports Python 2.6 and Python 3

if you are already using jQuery in your build just do this:

$(yourObject).length

It works nicely for me on objects, and I already had jQuery as a dependancy.

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

Given that, you have one of two solutions:

First solution, abandon JQuery and use XMLHTTPRequest

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

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

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

  req.send();

Second solution, use the jquery-ajax-native plugin

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

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

Other than the builtin developer tools, there is none that i know of. You might, however, be able to use Firebug Lite.

A bit late but ... I found a link that I saved a couple of years ago and I thought it might be useful for you guys:

CDE: Automatically create portable Linux applications

http://www.pgbovine.net/cde.html

• Just download the program

• Execute the binary passing as a argument the name of the binary you want make portable, for example: nmap

  ./cde_2011-08-15_64bit nmap

The program will read all of libs linked to nmap and its dependencias and it will save all of them in a folder called cde-package/ (in the same directory that you are).

• Finally, you can compress the folder and deploy the portable binary in whatever system.

Remember, to launch the portable program you have to exec the binary located in cde-package/nmap.cde

Best regards

You can control it with CSS, there is a few options :

• hidden -> All text overflowing will be hidden.
• visible -> Let the text overflowing visible.
• scroll -> put scroll bars if the text overflows

Hope it helps.

It has already been mentioned that hashmaps are O(n/m) in average, if n is the number of items and m is the size. It has also been mentioned that in principle the whole thing could collapse into a singly linked list with O(n) query time. (This all assumes that calculating the hash is constant time).

However what isn't often mentioned is, that with probability at least 1-1/n (so for 1000 items that's a 99.9% chance) the largest bucket won't be filled more than O(logn)! Hence matching the average complexity of binary search trees. (And the constant is good, a tighter bound is (log n)*(m/n) + O(1)).

All that's required for this theoretical bound is that you use a reasonably good hash function (see Wikipedia: Universal Hashing. It can be as simple as a*x>>m). And of course that the person giving you the values to hash doesn't know how you have chosen your random constants.

TL;DR: With Very High Probability the worst case get/put complexity of a hashmap is O(logn).

FORMAT(X,D) Formats the number X to a format like '#,###,###.##', rounded to D decimal places, and returns the result as a string. If D is 0, the result has no decimal point or fractional part.

 SELECT FORMAT(12332.123456, 4);
        -> '12,332.1235'

I was having the exact same problem. I found the issue within bootstrap.min.css. You need to change the label: label {display:inline-block;} to label {display:block;}

Concepts

Observables in short tackles asynchronous processing and events. Comparing to promises this could be described as observables = promises + events.

What is great with observables is that they are lazy, they can be canceled and you can apply some operators in them (like map, ...). This allows to handle asynchronous things in a very flexible way.

A great sample describing the best the power of observables is the way to connect a filter input to a corresponding filtered list. When the user enters characters, the list is refreshed. Observables handle corresponding AJAX requests and cancel previous in-progress requests if another one is triggered by new value in the input. Here is the corresponding code:

this.textValue.valueChanges
    .debounceTime(500)
    .switchMap(data => this.httpService.getListValues(data))
    .subscribe(data => console.log('new list values', data));

(textValue is the control associated with the filter input).

Here is a wider description of such use case: How to watch for form changes in Angular 2?.

There are two great presentations at AngularConnect 2015 and EggHead:

• Observables vs promises - https://egghead.io/lessons/rxjs-rxjs-observables-vs-promises
• Creating-an-observable - https://egghead.io/lessons/rxjs-creating-an-observable
• RxJS In-Depth https://www.youtube.com/watch?v=KOOT7BArVHQ
• Angular 2 Data Flow - https://www.youtube.com/watch?v=bVI5gGTEQ_U

Christoph Burgdorf also wrote some great blog posts on the subject:

• http://blog.thoughtram.io/angular/2016/01/06/taking-advantage-of-observables-in-angular2.html
• http://blog.thoughtram.io/angular/2016/01/06/taking-advantage-of-observables-in-angular2.html

In action

In fact regarding your code, you mixed two approaches ;-) Here are they:

• Manage the observable by your own. In this case, you're responsible to call the subscribe method on the observable and assign the result into an attribute of the component. You can then use this attribute in the view for iterate over the collection:

  @Component({
    template: `
      <h1>My Friends</h1>
      <ul>
        <li *ngFor="#frnd of result">
          {{frnd.name}} is {{frnd.age}} years old.
        </li>
      </ul>
    `,
    directive:[CORE_DIRECTIVES]
  })
  export class FriendsList implement OnInit, OnDestroy {
    result:Array<Object>; 
  
    constructor(http: Http) {
    }
  
    ngOnInit() {
      this.friendsObservable = http.get('friends.json')
                    .map(response => response.json())
                    .subscribe(result => this.result = result);
     }
  
     ngOnDestroy() {
       this.friendsObservable.dispose();
     }
  }
  

  Returns from both get and map methods are the observable not the result (in the same way than with promises).

• Let manage the observable by the Angular template. You can also leverage the async pipe to implicitly manage the observable. In this case, there is no need to explicitly call the subscribe method.

  @Component({
    template: `
      <h1>My Friends</h1>
      <ul>
        <li *ngFor="#frnd of (result | async)">
          {{frnd.name}} is {{frnd.age}} years old.
        </li>
      </ul>
    `,
    directive:[CORE_DIRECTIVES]
  })
  export class FriendsList implement OnInit {
    result:Array<Object>; 
  
    constructor(http: Http) {
    }
  
    ngOnInit() {
      this.result = http.get('friends.json')
                    .map(response => response.json());
     }
  }
  

You can notice that observables are lazy. So the corresponding HTTP request will be only called once a listener with attached on it using the subscribe method.

You can also notice that the map method is used to extract the JSON content from the response and use it then in the observable processing.

Hope this helps you, Thierry

1) Using inline styles

<div [style.color]="myDynamicColor">

2) Use multiple CSS classes mapping to what you want and switch classes like:

 /* CSS */
 .theme { /* any shared styles */ }
 .theme.blue { color: blue; }
 .theme.red { color: red; }

 /* Template */
 <div class="theme" [ngClass]="{blue: isBlue, red: isRed}">
 <div class="theme" [class.blue]="isBlue">

Code samples from: https://angular.io/cheatsheet

More info on ngClass directive : https://angular.io/docs/ts/latest/api/common/index/NgClass-directive.html

You can do it with:

UPDATE mytable SET Total = Pieces * Price;

If you want to have your ls colorized you have to edit your ~/.bash_profile file and add the following line (if not already written) :

source .bashrc

Then you edit or create ~/.bashrc file and write an alias to the ls command :

alias ls="ls -G"

Now you have to type source .bashrc in a terminal if already launched, or simply open a new terminal.

If you want more options in your ls juste read the manual ( man ls ). Options are not exactly the same as in a GNU/Linux system.

These answers are right, but old and works for Depoloyement Package Model. What I Actually needed is to change the server name, database name of a connection manager and i found this very helpful:

If you are going to use this conversion a lot, consider calculating once and putting the results in a dictionary:

>>> import string
>>> di=dict(zip(string.letters,[ord(c)%32 for c in string.letters]))
>>> di['c'] 
3

The advantage is dictionary lookups are very fast vs iterating over a list on every call.

>>> for c in sorted(di.keys()):
>>>    print "{0}:{1}  ".format(c, di[c])
# what you would expect....

I would store a user ID and a token. When the user comes back to the site, compare those two pieces of information against something persistent like a database entry.

As for security, just don't put anything in there that will allow someone to modify the cookie to gain extra benefits. For example, don't store their user groups or their password. Anything that can be modified that would circumvent your security should not be stored in the cookie.

You could subscribe for the onkeypress event:

<input type="text" class="textfield" value="" id="extra7" name="extra7" onkeypress="return isNumber(event)" />

and then define the isNumber function:

function isNumber(evt) {
    evt = (evt) ? evt : window.event;
    var charCode = (evt.which) ? evt.which : evt.keyCode;
    if (charCode > 31 && (charCode < 48 || charCode > 57)) {
        return false;
    }
    return true;
}

You can see it in action here.

An Outlet is a link from code to UI. If you want to show or hide an UI element, if you want to get the text of a textfield or enable or disable an element (or a hundred other things) you have to define an outlet of that object in the sources and link that outlet through the “interface object” to the UI element. After that you can use the outlet just like any other variable in your coding.

IBAction – a special method triggered by user-interface objects. Interface Builder recognizes them.

@interface Controller
{
  IBOutlet id textField; // links to TextField UI object
}

- (IBAction)doAction:(id)sender; // e.g. called when button pushed

If the folder is not empty, a slightly modified version of @JohnLittle's answer worked for me:

git init
git remote add origin https://github.com/me/name.git
git pull origin master

As @peter-cordes pointed out, the only difference is using https protocol instead of git, for which you need to have SSH keys configured.

The first thing you tried seems to work fine. Here is an example program.
Press the "Start" button at the top of this page to run it to see the output yourself.

import java.util.Arrays;

public class Foo{
    public static void main(String[] args) {
        String [] stringArray = {"ab", "aB", "c", "0", "2", "1Ad", "a10"};
        orderedGuests(stringArray);
    }

    public static void orderedGuests(String[] hotel)
    {
        Arrays.sort(hotel);
        System.out.println(Arrays.toString(hotel));
    }
}

I tried your code, you didn't assign/bind a value to your formControlName.

In HTML file:

<form [formGroup]="form">
   <label>
     <input type="radio" value="Male" formControlName="gender">
       <span>male</span>
   </label>
   <label>
     <input type="radio" value="Female" formControlName="gender">
       <span>female</span>
   </label>
</form>

In the TS file:

  form: FormGroup;
  constructor(fb: FormBuilder) {
    this.name = 'Angular2'
    this.form = fb.group({
      gender: ['', Validators.required]
    });
  }

Make sure you use Reactive form properly: [formGroup]="form" and you don't need the name attribute.

In my sample. words male and female in span tags are the values display along the radio button and Male and Female values are bind to formControlName

See the screenshot:

To make it shorter:

<form [formGroup]="form">
  <input type="radio" value='Male' formControlName="gender" >Male
  <input type="radio" value='Female' formControlName="gender">Female
</form>

Hope it helps:)

String[] result = "hi i'm paul".split("\\s+"); to split across one or more cases.

Or you could take a look at Apache Common StringUtils. It has StringUtils.split(String str) method that splits string using white space as delimiter. It also has other useful utility methods

Use SELECT or an output parameter. More can be found here: http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=100201

In your .button CSS, try display:inline-block. See this JSFiddle

Happened with a colleague. If development environment is windows and visual studio project is on C: drive.. Than make sure that visual studio is run with administrator right.. simply right click and 'Run as administrator'. You can also go to the properties of visual studio project -> Advance -> and enable 'Run as administrator'.

As Ennui mentioned, IE 10 supports the -ms prefixed version of Flexbox (IE 11 supports it unprefixed). The errors I can see in your code are:

• You should have display: -ms-flexbox instead of display: -ms-flex
• I think you should specify all 3 flex values, like flex: 0 1 auto to avoid ambiguity

So the final updated code is...

.flexbox form {
    display: -webkit-flex;
    display: -moz-flex;
    display: -ms-flexbox;
    display: -o-flex;
    display: flex;

    /* Direction defaults to 'row', so not really necessary to specify */
    -webkit-flex-direction: row;
    -moz-flex-direction: row;
    -ms-flex-direction: row;
    -o-flex-direction: row;
    flex-direction: row;
}

.flexbox form input[type=submit] {
    width: 31px;
}

.flexbox form input[type=text] {
    width: auto;

    /* Flex should have 3 values which is shorthand for 
       <flex-grow> <flex-shrink> <flex-basis> */
    -webkit-flex: 1 1 auto;
    -moz-flex: 1 1 auto;
    -ms-flex: 1 1 auto;
    -o-flex: 1 1 auto;
    flex: 1 1 auto;

    /* I don't think you need 'display: flex' on child elements * /
    display: -webkit-flex;
    display: -moz-flex;
    display: -ms-flex;
    display: -o-flex;
    display: flex;
    /**/
}

Install pip:

apt-get install pip

For acess MySQL from Python, install:

pip3 install mysqlclient

u must specify the width and height also

 <section class="bg-solid-light slideContainer strut-slide-0" style="background-image: url(https://accounts.icharts.net/stage/icharts-images/chartbook-images/Chart1457601371484.png); background-repeat: no-repeat;width: 100%;height: 100%;" >

you will get the time without specifying the date format. convert the string to date using Date object

var myDate = new Date('Mon 03-Jul-2017, 06:00 PM');

working solution:

var myDate= new Date('Mon 03-Jul-2017, 06:00 PM');_x000D_
console.log(moment(myDate).format('HH:mm')); // 24 hour format _x000D_
console.log(moment(myDate).format('hh:mm'));_x000D_
console.log(moment(myDate).format('hh:mm A'));

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>

It has nothing to do with your form or the values in it. It gets fired by the browser to prevent the user from repeating the same request with the cached data. If you really need to enable the refreshing of the result page, you should redirect the user, either via PHP (header('Location:result.php');) or other server-side language you're using. Meta tag solution should work also to disable the resending on refresh.

I use Node version manager (called n) for it.

npm install -g n

then

n latest

OR

n stable

For those who using a newer swagger 3 version org.springdoc:springdoc-openapi-ui

}

I don't know about performance difference, but as you say, static nested class is not a part of an instance of the enclosing class. Seems just simpler to create a static nested class unless you really need it to be an inner class.

It's a bit like why I always make my variables final in Java - if they're not final, I know there's something funny going on with them. If you use an inner class instead of a static nested class, there should be a good reason.

i had the same issue and tried a few of the given solutions but it still didn't work. all i did was to run the "npx yarn" command in the root folder of my project and that was it.

request.args is a MultiDict with the parsed contents of the query string. From the documentation of get method:

get(key, default=None, type=None)

Return the default value if the requested data doesn’t exist. If type is provided and is a callable it should convert the value, return it or raise a ValueError if that is not possible.

This problem appear if two software use same port for connecting to the server
try to close the port by cmd according to your operating system
then reboot your Android studio or your Eclipse or your Software.

I would suggest using map/reduce, where you use the map function to only emit when a random value is above a given probability.

function mapf() {
    if(Math.random() <= probability) {
    emit(1, this);
    }
}

function reducef(key,values) {
    return {"documents": values};
}

res = db.questions.mapReduce(mapf, reducef, {"out": {"inline": 1}, "scope": { "probability": 0.5}});
printjson(res.results);

The reducef function above works because only one key ('1') is emitted from the map function.

The value of the "probability" is defined in the "scope", when invoking mapRreduce(...)

Using mapReduce like this should also be usable on a sharded db.

If you want to select exactly n of m documents from the db, you could do it like this:

function mapf() {
    if(countSubset == 0) return;
    var prob = countSubset / countTotal;
    if(Math.random() <= prob) {
        emit(1, {"documents": [this]}); 
        countSubset--;
    }
    countTotal--;
}

function reducef(key,values) {
    var newArray = new Array();
for(var i=0; i < values.length; i++) {
    newArray = newArray.concat(values[i].documents);
}

return {"documents": newArray};
}

res = db.questions.mapReduce(mapf, reducef, {"out": {"inline": 1}, "scope": {"countTotal": 4, "countSubset": 2}})
printjson(res.results);

Where "countTotal" (m) is the number of documents in the db, and "countSubset" (n) is the number of documents to retrieve.

This approach might give some problems on sharded databases.

What client do you use? .Net, Java, Ruby, SQLPLUS, SQL DEVELOPER? Where did you write that simple select statement?

And why do you want to read the content of the blob, a blob contains binary data so that data is unreadable. You should use a clob instead of a blob if you want to store text instead of binary content.

I suggest that you download SQL DEVELOPER: http://www.oracle.com/technetwork/developer-tools/sql-developer/overview/index.html . With SQL DEVELOPER you can see the content.

Re-review the Android Activity Lifecycle reference. There is a nice picture, and the table showing what methods get called. reference Link google

https://developer.android.com/reference/android/app/Activity.html

you can try to get it in a lot of ways :

1.Using media="bogus" and a <link> at the foot

<head>
    <!-- unimportant nonsense -->
    <link rel="stylesheet" href="style.css" media="bogus">
</head>
<body>
    <!-- other unimportant nonsense, such as content -->
    <link rel="stylesheet" href="style.css">
</body>

2.Inserting DOM in the old way

<script type="text/javascript">
(function(){
  var bsa = document.createElement('script');
     bsa.type = 'text/javascript';
     bsa.async = true;
     bsa.src = 'https://s3.buysellads.com/ac/bsa.js';
  (document.getElementsByTagName('head')[0]||document.getElementsByTagName('body')[0]).appendChild(bsa);
})();
</script>

3.if you can try plugins you could try loadCSS

<script>
  // include loadCSS here...
  function loadCSS( href, before, media ){ ... }
  // load a file
  loadCSS( "path/to/mystylesheet.css" );
</script>

5. At the mysql command line enter: use mysql;

Then execute this query:

insert into `user` (`Host`, `User`, `Password`, `Select_priv`, `Insert_priv`, `Update_priv`, `Delete_priv`, `Create_priv`, `Drop_priv`, `Reload_priv`, `Shutdown_priv`, `Process_priv`, `File_priv`, `Grant_priv`, `References_priv`, `Index_priv`, `Alter_priv`, `Show_db_priv`, `Super_priv`, `Create_tmp_table_priv`, `Lock_tables_priv`, `Execute_priv`, `Repl_slave_priv`, `Repl_client_priv`, `Create_view_priv`, `Show_view_priv`, `Create_routine_priv`, `Alter_routine_priv`, `Create_user_priv`, `ssl_type`, `ssl_cipher`, `x509_issuer`, `x509_subject`, `max_questions`, `max_updates`, `max_connections`, `max_user_connections`)

then restart the mysqld

EDIT: October 6, 2018

In case anyone else needs this answer, I tried it today using innodb_version 5.6.36-82.0 and 10.1.24-MariaDB and it works if you REMOVE THE BACKTICKS (no single quotes either, just remove them):

insert into user (Host, User, Password, Select_priv, Insert_priv, Update_priv, Delete_priv, Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv, File_priv, Grant_priv, References_priv, Index_priv, Alter_priv, Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv, Execute_priv, Repl_slave_priv, Repl_client_priv, Create_view_priv, Show_view_priv, Create_routine_priv, Alter_routine_priv, Create_user_priv, ssl_type, ssl_cipher, x509_issuer, x509_subject, max_questions, max_updates, max_connections, max_user_connections) 
values('localhost','root','','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','','','','','0','0','0','0');

This behavior is related to Zone that is set - Internet/Intranet/etc and corresponding Security Level

You can change this by setting less secure Security Level (not recommended) or by customizing Display Mixed Content property

You can do that by following steps:

1. Click on Gear icon at the top of the browser window.
2. Select Internet Options.
3. Select the Security tab at the top.
4. Click the Custom Level... button.
5. Scroll about halfway down to the Miscellaneous heading (denoted by a "blank page" icon).
6. Under this heading is the option Display Mixed Content; set this to Enable/Prompt.
7. Click OK, then Yes when prompted to confirm the change, then OK to close the Options window.
8. Close and restart the browser.

This can happen on Windows after a java update where the old version of the java SDK is missing and a new one is present. I would check if your IDE is using the installed java SDK version (IntelliJ: CTRL + SHIFT + ALT + S)

Start with the use of tabs - the \t character modifier. It will advance to a fixed location (columns, terminal lingo).

However, it doesn't help if there are differences of more than the column width (4 characters, if I recall correctly).

To fix that, write your "OK/NOK" stuff using a fixed number of tabs (5? 6?, try it). Then return (\r) without new-lining, and write your message.

In case of you decided the debug your apk which is already in market but not assigned to be debuggable and you do not want to publish it again. So follow the below steps;

1. Decompile the Apk with ApkTool(eg. apktool d <APK_PATH>)
2. Open the AndroidManifest.xml from decompiled files
3. Set android:debuggable="true" in application tag
4. Compile the modified source with ApkTool (eg. apktool b <MODIFIED_PATH>)
5. Debuggable apk ready(which unsigned means cannot publish store). You can debug as you wish.

After a lot of fiddling I found a better answer at sqlite docs for listing the metadata for the table, even attached databases.

meta = cursor.execute("PRAGMA table_info('Job')")
for r in meta:
    print r

The key information is to prefix table_info, not my_table with the attachment handle name.

I'm using Ubuntu 18.04 LTS. Most of the time, when I change my java version, I also want to use the same javac version.
I use update-alternatives this way, using a java_home alternative instead :

Installation

Install every java version in /opt/java/<version>, for example

~$ ll /opt/java/
total 24
drwxr-xr-x 6 root root 4096 jan. 22 21:14 ./
drwxr-xr-x 9 root root 4096 feb.  7 13:40 ../
drwxr-xr-x  8 stephanecodes stephanecodes 4096 jan.   8  2019 jdk-11.0.2/
drwxr-xr-x  7 stephanecodes stephanecodes 4096 dec.  15  2018 jdk1.8.0_201/

Configure alternatives

~$ sudo update-alternatives --install /opt/java/current java_home /opt/java/jdk-11.0.2/ 100
~$ sudo update-alternatives --install /opt/java/current java_home /opt/java/jdk1.8.0_201 200

Declare JAVA_HOME (In this case, I use a global initialization script for this)

~$ sudo sh -c 'echo export JAVA_HOME=\"/opt/java/current\" >> environment.sh'

Log Out or restart Ubuntu (this will reload /etc/profile.d/environment.sh)

Usage

Change java version

Choose the version you want to use

~$ sudo update-alternatives --config java_home

There are 2 choices for the alternative java_home (providing /opt/java/current).

  Selection    Path                    Priority   Status
------------------------------------------------------------
  0            /opt/java/jdk-11.0.2     200       auto mode
  1            /opt/java/jdk-11.0.2     200       manual mode
* 2            /opt/java/jdk1.8.0_201   100       manual mode

Press <enter> to keep the current choice[*], or type selection number: 

Check version

~$ java -version
openjdk version "11.0.2" 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

~$ javac -version
javac 11.0.2

Tip

Add the following line to ~/.bash_aliases file :

alias change-java-version="sudo update-alternatives --config java_home && java -version && javac -version"

Now use the change-java-version command to change java version

Perhaps your code is behind Sheet1, so when you change the focus to Sheet2 the objects cannot be found? If that's the case, simply specifying your target worksheet might help:

Sheets("Sheet1").Range("C21").Select

I'm not very familiar with how Select works because I try to avoid it as much as possible :-). You can define and manipulate ranges without selecting them. Also it's a good idea to be explicit about everything you reference. That way, you don't lose track if you go from one sheet or workbook to another. Try this:

Option Explicit

Sub CopySheet1_to_PasteSheet2()

    Dim CLastFundRow As Integer
    Dim CFirstBlankRow As Integer
    Dim wksSource As Worksheet, wksDest As Worksheet
    Dim rngStart As Range, rngSource As Range, rngDest As Range

    Set wksSource = ActiveWorkbook.Sheets("Sheet1")
    Set wksDest = ActiveWorkbook.Sheets("Sheet2")

    'Finds last row of content
    CLastFundRow = wksSource.Range("C21").End(xlDown).Row
    'Finds first row without content
    CFirstBlankRow = CLastFundRow + 1

    'Copy Data
    Set rngSource = wksSource.Range("A2:C" & CLastFundRow)

    'Paste Data Values
    Set rngDest = wksDest.Range("A21")
    rngSource.Copy
    rngDest.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:=False, Transpose:=False
    'Bring back to top of sheet for consistancy
    wksDest.Range("A1").Select

End Sub

Can try with below code

 WebDriverWait wait = new WebDriverWait(driver, 30);

Pass other element would receive the click:<a class="navbar-brand" href="#"></a>

    boolean invisiable = wait.until(ExpectedConditions
            .invisibilityOfElementLocated(By.xpath("//div[@class='navbar-brand']")));

Pass clickable button id as shown below

    if (invisiable) {
        WebElement ele = driver.findElement(By.xpath("//div[@id='button']");
        ele.click();
    }

If the object is actually a Boolean instance, then just cast it:

boolean di = (Boolean) someObject;

The explicit cast will do the conversion to Boolean, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:

boolean di = ((Boolean) someObject).booleanValue();

If someObject doesn't refer to a Boolean value though, what do you want the code to do?

If the visual studio says that you miss some file in the current source file folder, there is one solution that i used. Just right click the file you want to add and choose Open Document, if it really doesn't exist, then you should see something like cannot find file in the source file path = "somewhere in your computer", then what you could do is the add your source file into that path first and see if it works.

Simply add a -h after adding your credentials using a -u -p, and it will run with elevated privileges.

You can use it like this:

In Mvc:

@Html.TextBoxFor(x=>x.Id,new{@data_val_number="10"});

In Html:

<input type="text" name="Id" data_val_number="10"/>

Few answers have given a solution with height and width 100% but I recommend you to not use percentage in css, use top/bottom and left/right positionning.

This is a better approach that allow you to control margin.

Here is the code :

body {
    position: relative;
    height: 3000px;
}
body div {

    top:0px;
    bottom: 0px;
    right: 0px;
    left:0px;
    background-color: yellow;
    position: absolute;
}

I've finally found the issue here. Even though the firewall was turned off at both the locations we found that a router in the SQLB data center was actively blocking UDP 1434. I was able to determine this by installing the PorQry tool by Microsoft (http://www.microsoft.com/en-ca/download/details.aspx?id=17148) and running a query against the UDP port. Then I installed WireShark (http://www.wireshark.org/) to view the actual connection details and found the router in question that was refusing to forward the request. Since this router only affected SQLB this explains why every other connection worked fine.

Thanks everyone for your suggestions and assistance!

This:

ORDER BY 1

...is known as an "Ordinal" - the number stands for the column based on the number of columns defined in the SELECT clause. In the query you provided, it means:

ORDER BY A.PAYMENT_DATE

It's not a recommended practice, because:

1. It's not obvious/explicit
2. If the column order changes, the query is still valid so you risk ordering by something you didn't intend

An alternative to whoami is id -u -n.

id -u will return the user id (e.g. 0 for root).

Just add a contructor to your service class (if you don't have it already). Below, you can check and example for visual basic .net.

Public Sub New()
   OnStart(Nothing) 
End Sub

After, that, right-click on project and select "Debug -> Start a new instance".

Simply you could use:

PartialView("../ABC/XXX")

First of all, I think you've misunderstood what the viewport is. The viewport is the area a browser uses to render web pages, and you cannot in any way build your web sites to override this area in any way.

Secondly, it seems that the reason that your overlay-div won't cover the entire viewport is because you have to remove all margins on BODY and HTML.

Try adding this at the top of your stylesheet - it resets all margins and paddings on all elements. Makes further development easier:

* { margin: 0; padding: 0; }

Edit: I just understood your question better. Position: fixed; will probably work out for you, as Jonathan Sampson have written.

binary search runs in O(logn) time whereas linear search runs in O(n) times thus binary search has better performance

You can also try this

string.Join(null,System.Text.RegularExpressions.Regex.Split(expr, "[^\\d]"));

In the controller action append to the header the following lines

    public ActionResult Create(string PositionID)
    {
        Response.AppendHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
        Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.0.
        Response.AppendHeader("Expires", "0"); // Proxies.

In intelliJ (and probably in eclipse also) you can filter the logcat output by text webview, so it prints basically everything phonegap is producing

For me trying above techniques did work so I opened .bash_profile file and added following line in new line to connect to maven using short cmd :

alias mvn=/opt/apache-maven-3.6.3/bin/mvn

Restart your terminal and hit mvn clean install cmd

In addition to the accepted answer, you can also achieve what you originally wanted (creating a deployment using the run command) with the following command:

kubectl run hdfs --image=fluxcapacitor/hdfs:latest --port=8989 --generator=run-pod/v1 

I found the information about the generator on the Kubernetes-dev forum:

If you're using kubectl run, it generates a manifest for you that happens to have imagePullPolicy set to Always by default. You can use this command to get an imagePullPolicy of IfNotPresent, which will work for minikube:

kubectl run --image=<container> --generator=run-pod/v1

Yes you can (this is how I understand the original question). Here is how I did it. Just tie it into outside context. For example:

//javascript

my_function = null;

//jquery 
 $(function() { 

        function my_fun(){ 
               /.. some operations ../ 
        }  
        my_function = my_fun;
 }) 

 //just js 
 function js_fun () {  
       my_function(); //== call jquery function - just Reference is globally defined not function itself
}

I encountered this same problem when trying to access methods of the object, that was instantiated on DOM object ready only. Works. My example:

MyControl.prototype = {
   init:   function { 
        // init something
   }
   update: function () {
           // something useful, like updating the list items of control or etc.         
   }
}

MyCtrl = null;

// create jquery plug-in
$.fn.aControl = function () {
    var control = new MyControl(this);
    control.init();
    MyCtrl = control; // here is the trick
    return control;
}

now you can use something simple like:

function() = {
   MyCtrl.update(); // yes!
}

Here are some simple techniques for vertical-align:

One-line vertical-align:middle

This one is easy: set the line-height of the text element to equal that of the container

<div>
  <img style="width:30px; height:30px;">
  <span style="line-height:30px;">Doesn't work.</span>
</div>

Multiple-lines vertical-align:bottom

Absolutely position an inner div relative to its container

<div style="position:relative;width:30px;height:60px;">
  <div style="position:absolute;bottom:0">This is positioned on the bottom</div>
</div>

Multiple-lines vertical-align:middle

<div style="display:table;width:30px;height:60px;">
  <div style="display:table-cell;height:30px;">This is positioned in the middle</div>
</div>

If you must support ancient versions of IE <= 7

In order to get this to work correctly across the board, you'll have to hack the CSS a bit. Luckily, there is an IE bug that works in our favor. Setting top:50% on the container and top:-50% on the inner div, you can achieve the same result. We can combine the two using another feature IE doesn't support: advanced CSS selectors.

<style type="text/css">
  #container {
    width: 30px;
    height: 60px;
    position: relative;
  }
  #wrapper > #container {
    display: table;
    position: static;
  }
  #container div {
    position: absolute;
    top: 50%;
  }
  #container div div {
    position: relative;
    top: -50%;
  }
  #container > div {
    display: table-cell;
    vertical-align: middle;
    position: static;
  }
</style>

<div id="wrapper">
  <div id="container">
    <div><div><p>Works in everything!</p></div></div>
  </div>
</div>

Variable container height vertical-align:middle

This solution requires a slightly more modern browser than the other solutions, as it makes use of the transform: translateY property. (http://caniuse.com/#feat=transforms2d)

Applying the following 3 lines of CSS to an element will vertically centre it within its parent regardless of the height of the parent element:

position: relative;
top: 50%;
transform: translateY(-50%);

select MY_SEQ_NAME.currval from DUAL;

Keep in mind that it only works if you ran select MY_SEQ_NAME.nextval from DUAL; in the current sessions.

Assuming that your original dataset is similar to the one you created (i.e. with NA as character. You could specify na.strings while reading the data using read.table. But, I guess NAs would be detected automatically.

The price column is factor which needs to be converted to numeric class. When you use as.numeric, all the non-numeric elements (i.e. "NA", FALSE) gets coerced to NA) with a warning.

library(dplyr)
df %>%
     mutate(price=as.numeric(as.character(price))) %>%  
     group_by(company, year, product) %>%
     summarise(total.count=n(), 
               count=sum(is.na(price)), 
               avg.price=mean(price,na.rm=TRUE),
               max.price=max(price, na.rm=TRUE))

data

I am using the same dataset (except the ... row) that was showed.

df = tbl_df(data.frame(company=c("Acme", "Meca", "Emca", "Acme", "Meca","Emca"),
 year=c("2011", "2010", "2009", "2011", "2010", "2013"), product=c("Wrench", "Hammer",
 "Sonic Screwdriver", "Fairy Dust", "Kindness", "Helping Hand"), price=c("5.67",
 "7.12", "12.99", "10.99", "NA",FALSE)))

I recently came to a similar situation where I needed to register a handler for an event only once. I found that you can safely unregister first, and then register again, even if the handler is not registered at all:

myClass.MyEvent -= MyHandler;
myClass.MyEvent += MyHandler;

Note that doing this every time you register your handler will ensure that your handler is registered only once. Sounds like a pretty good practice to me :)

If the formatting template was read from a file, and you cannot ensure the content doubles the percent sign, then you probably have to detect the percent character and decide programmatically whether it is the start of a placeholder or not. Then the parser should also recognize sequences like %d (and other letters that can be used), but also %(xxx)s etc.

Similar problem can be observed with the new formats -- the text can contain curly braces.

An example done by me using the scroll (just HTML, CSS and JS, just with the jquery library). When scrolls down a button will slide left.

Also, I suggest you if the only one that you want is this effect, don't use jQuery UI because it's too heavy(if you just want to use it for that).

$(window).scroll(function(){
  if ($(this).scrollTop() > 100) {
          event.preventDefault();
          $(".scrollToTop").css({'transform': 'translate(0px, 0px)'});
      } else {
          $(".scrollToTop").css({'transform': 'translate(40px, 0px)'});
      }
  });

Check this example

It seems you now do not need to reverse geocode and now get the address directly from ClientLocation:

google.loader.ClientLocation.address.city

I found that "phpseclib" should help you with this (SFTP and many more features). http://phpseclib.sourceforge.net/

To Put the file to the server, simply call (Code example from http://phpseclib.sourceforge.net/sftp/examples.html#put)

<?php
include('Net/SFTP.php');

$sftp = new Net_SFTP('www.domain.tld');
if (!$sftp->login('username', 'password')) {
    exit('Login Failed');
}

// puts a three-byte file named filename.remote on the SFTP server
$sftp->put('filename.remote', 'xxx');
// puts an x-byte file named filename.remote on the SFTP server,
// where x is the size of filename.local
$sftp->put('filename.remote', 'filename.local', NET_SFTP_LOCAL_FILE);

I had a similar problem that it was denying to run on port 8080, but also any other.

Turns out, it was because the env.local file it read contained comments after the variable names like:

PORT=8080 # The port the server runs at

And it interpreted it like that, trying to use port "8080 # The port the server runs at", which is obviously an invalid port (-1). Removing the comments entirely solved it.

Using Windows 10 and Git Bash by the way.

I know it's not exactly the problem described here, but it might help someone out there. I landed on this question searching for the problem for my answer, so... maybe?

Check the complete and naturalWidth properties, in that order.

https://stereochro.me/ideas/detecting-broken-images-js

function IsImageOk(img) {
    // During the onload event, IE correctly identifies any images that
    // weren’t downloaded as not complete. Others should too. Gecko-based
    // browsers act like NS4 in that they report this incorrectly.
    if (!img.complete) {
        return false;
    }

    // However, they do have two very useful properties: naturalWidth and
    // naturalHeight. These give the true size of the image. If it failed
    // to load, either of these should be zero.
    if (img.naturalWidth === 0) {
        return false;
    }

    // No other way of checking: assume it’s ok.
    return true;
}

You could maybe add a method to your Production object called 'SetPowerRating(int)' which sets a property in Production, and call this in your Meter object before using the property in the Production object?
