                var input = $(this);

                $(input).focus(function() {
                    if (input.val() == input.attr('placeholder')) {
                        input.val('');
                    }
                });

                $(input).blur(function() {

Adapted from this answer:

function scroll(y, duration) {

    var initialY = document.documentElement.scrollTop || document.body.scrollTop;
    var baseY = (initialY + y) * 0.5;
    var difference = initialY - baseY;
    var startTime = performance.now();

    function step() {
        var normalizedTime = (performance.now() - startTime) / duration;
        if (normalizedTime > 1) normalizedTime = 1;

        window.scrollTo(0, baseY + difference * Math.cos(normalizedTime * Math.PI));
        if (normalizedTime < 1) window.requestAnimationFrame(step);
    }
    window.requestAnimationFrame(step);
}

This should allow you to smoothly scroll (cosine function) from anywhere to the specified "y".

I have some general thoughts about the implementation of Task:

1. Task is disposable yet we are not supposed to use using.
2. ConfigureAwait was introduced in 4.5. Task was introduced in 4.0.
3. .NET Threads always used to flow the context (see C# via CLR book) but in the default implementation of Task.ContinueWith they do not b/c it was realised context switch is expensive and it is turned off by default.
4. The problem is a library developer should not care whether its clients need context flow or not hence it should not decide whether flow the context or not.
5. [Added later] The fact that there is no authoritative answer and proper reference and we keep fighting on this means someone has not done their job right.

I have got a few posts on the subject but my take - in addition to Tugberk's nice answer - is that you should turn all APIs asynchronous and ideally flow the context . Since you are doing async, you can simply use continuations instead of waiting so no deadlock will be cause since no wait is done in the library and you keep the flowing so the context is preserved (such as HttpContext).

Problem is when a library exposes a synchronous API but uses another asynchronous API - hence you need to use Wait()/Result in your code.

I generally like the shorthand version:

if (!!wlocation) { window.location = wlocation; }

This is useful when you want to compare data that correspond to different units. In that case, you want to remove the units. To do that in a consistent way of all the data, you transform the data in a way that the variance is unitary and that the mean of the series is 0.

Swift version of @Nicolas Bonnet 's answer:

    var popupWindow: UIWindow?

func showViewController(controller: UIViewController) {
    self.popupWindow = UIWindow(frame: UIScreen.mainScreen().bounds)
    controller.view.frame = self.popupWindow!.bounds
    self.popupWindow!.rootViewController = controller
    self.popupWindow!.makeKeyAndVisible()
}

func viewControllerDidRemove() {
    self.popupWindow?.removeFromSuperview()
    self.popupWindow = nil
}

Don't forget that the window must be a strong property, because the original answer leads to an immediate deallocation of the window

Try this:

$old_date = date('y-m-d-h-i-s');
$new_date = date('Y-m-d H:i:s', strtotime($old_date));

Python 3 has the facility of Launching parallel tasks. This makes our work easier.

It has for thread pooling and Process pooling.

The following gives an insight:

ThreadPoolExecutor Example

import concurrent.futures
import urllib.request

URLS = ['http://www.foxnews.com/',
        'http://www.cnn.com/',
        'http://europe.wsj.com/',
        'http://www.bbc.co.uk/',
        'http://some-made-up-domain.com/']

# Retrieve a single page and report the URL and contents
def load_url(url, timeout):
    with urllib.request.urlopen(url, timeout=timeout) as conn:
        return conn.read()

# We can use a with statement to ensure threads are cleaned up promptly
with concurrent.futures.ThreadPoolExecutor(max_workers=5) as executor:
    # Start the load operations and mark each future with its URL
    future_to_url = {executor.submit(load_url, url, 60): url for url in URLS}
    for future in concurrent.futures.as_completed(future_to_url):
        url = future_to_url[future]
        try:
            data = future.result()
        except Exception as exc:
            print('%r generated an exception: %s' % (url, exc))
        else:
            print('%r page is %d bytes' % (url, len(data)))

Another Example

import concurrent.futures
import math

PRIMES = [
    112272535095293,
    112582705942171,
    112272535095293,
    115280095190773,
    115797848077099,
    1099726899285419]

def is_prime(n):
    if n % 2 == 0:
        return False

    sqrt_n = int(math.floor(math.sqrt(n)))
    for i in range(3, sqrt_n + 1, 2):
        if n % i == 0:
            return False
    return True

def main():
    with concurrent.futures.ThreadPoolExecutor(max_workers=5) as executor:

After installing an animation module then you create an animation file inside your app folder.

router.animation.ts

import { animate, state, style, transition, trigger } from '@angular/animations';
    export function routerTransition() {
        return slideToTop();
    }

    export function slideToRight() {
        return trigger('routerTransition', [
            state('void', style({})),
            state('*', style({})),
            transition(':enter', [
                style({ transform: 'translateX(-100%)' }),
                animate('0.5s ease-in-out', style({ transform: 'translateX(0%)' }))
            ]),
            transition(':leave', [
                style({ transform: 'translateX(0%)' }),
                animate('0.5s ease-in-out', style({ transform: 'translateX(100%)' }))
            ])
        ]);
    }

    export function slideToLeft() {
        return trigger('routerTransition', [
            state('void', style({})),
            state('*', style({})),
            transition(':enter', [
                style({ transform: 'translateX(100%)' }),
                animate('0.5s ease-in-out', style({ transform: 'translateX(0%)' }))
            ]),
            transition(':leave', [
                style({ transform: 'translateX(0%)' }),
                animate('0.5s ease-in-out', style({ transform: 'translateX(-100%)' }))
            ])
        ]);
    }

    export function slideToBottom() {
        return trigger('routerTransition', [
            state('void', style({})),
            state('*', style({})),
            transition(':enter', [
                style({ transform: 'translateY(-100%)' }),
                animate('0.5s ease-in-out', style({ transform: 'translateY(0%)' }))
            ]),
            transition(':leave', [
                style({ transform: 'translateY(0%)' }),
                animate('0.5s ease-in-out', style({ transform: 'translateY(100%)' }))
            ])
        ]);
    }

    export function slideToTop() {
        return trigger('routerTransition', [
            state('void', style({})),
            state('*', style({})),
            transition(':enter', [
                style({ transform: 'translateY(100%)' }),
                animate('0.5s ease-in-out', style({ transform: 'translateY(0%)' }))
            ]),
            transition(':leave', [
                style({ transform: 'translateY(0%)' }),
                animate('0.5s ease-in-out', style({ transform: 'translateY(-100%)' }))
            ])
        ]);
    }

Then you import this animation file to your any component.

In your component.ts file

import { routerTransition } from '../../router.animations';

@Component({
  selector: 'app-test',
  templateUrl: './test.component.html',
  styleUrls: ['./test.component.scss'],
  animations: [routerTransition()]
})

Don't forget to import animation in your app.module.ts

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

First you need to sort your array using:

Collections.sort(myArray);

Then you need to reverse the order from ascending to descending using:

Collections.reverse(myArray);

Oracle's locking concept is quite different from that of the other systems.

When a row in Oracle gets locked, the record itself is updated with the new value (if any) and, in addition, a lock (which is essentially a pointer to transaction lock that resides in the rollback segment) is placed right into the record.

This means that locking a record in Oracle means updating the record's metadata and issuing a logical page write. For instance, you cannot do SELECT FOR UPDATE on a read only tablespace.

More than that, the records themselves are not updated after commit: instead, the rollback segment is updated.

This means that each record holds some information about the transaction that last updated it, even if the transaction itself has long since died. To find out if the transaction is alive or not (and, hence, if the record is alive or not), it is required to visit the rollback segment.

Oracle does not have a traditional lock manager, and this means that obtaining a list of all locks requires scanning all records in all objects. This would take too long.

You can obtain some special locks, like locked metadata objects (using v$locked_object), lock waits (using v$session) etc, but not the list of all locks on all objects in the database.

If you are getting this from the Ditto command creating multiple instances of the same name (NOT the 'copy files' build phase), you may have to change the Product Module Name.

1. Click on your Target(s) Xcode is complaining about
2. Click on Build Settings
3. Search for Product Module Name
4. Change the name to something unique

We have a watch target and a few notification targets in our app, so I just put things like Extension on the end of the module name.

I found this solution originally here: https://forums.developer.apple.com/thread/103913

This is what I finally came up with, which works great!

{=SUM(IF((ISTEXT('Worksheet Name!A:A))+(ISTEXT('CCSA Associates'!E:E)),1,0))-1}

Don't forget since it is an array to type the formula above without the "{}", and to CTRL + SHIFT + ENTER instead of just ENTER for the "{}" to appear and for it to be entered properly.

if Data frame look like that:

group         name      count
fruit         apple     90
fruit         banana    150
fruit         orange    130
vegetable     broccoli  80
vegetable     kale      70
vegetable     lettuce   125

and OUTPUT could be like

   group    name  count
0  fruit   apple     90
1  fruit  banana    150
2  fruit  orange    130

if you use logical operator np.logical_not

df[np.logical_not(df['group'] == 'vegetable')]

more about

https://docs.scipy.org/doc/numpy-1.13.0/reference/routines.logic.html

other logical operators

1. logical_and(x1, x2, /[, out, where, ...]) Compute the truth value of x1 AND x2 element-wise.

2. logical_or(x1, x2, /[, out, where, casting, ...]) Compute the truth value of x1 OR x2 element-wise.

3. logical_not(x, /[, out, where, casting, ...]) Compute the truth value of NOT x element-wise.
4. logical_xor(x1, x2, /[, out, where, ..]) Compute the truth value of x1 XOR x2, element-wise.

This might be a little off the question, but for those interested in the randomness of the generated string, my answer would be:

import os
import string

def _pwd_gen(size=16):
    chars = string.letters
    chars_len = len(chars)
    return str().join(chars[int(ord(c) / 256. * chars_len)] for c in os.urandom(size))

See these answers and random.py's source for more insight.

Try this:

df[df['column_name'] == ''].index

and for NaNs you can try:

pd.isna(df['column_name'])

Use mysql_num_rows(), to check if rows are available or not

$result = mysql_query("SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName' LIMIT 1");
$num_rows = mysql_num_rows($result);

if ($num_rows > 0) {
  // do something
}
else {
  // do something else
}

JLabel is actually capable of displaying some rudimentary HTML, which is why it is not responding to your use of the newline character (unlike, say, System.out).

If you put in the corresponding HTML and used <BR>, you would get your newlines.

Not really, in the standard. Some implementations have a nonstandard itoa() function, and you could look up Boost's lexical_cast, but if you stick to the standard it's pretty much a choice between stringstream and sprintf() (snprintf() if you've got it).

You could use assign, but using assign (or get) is often a symptom of a programming structure that is not very R like. Typically, lists or matrices allow cleaner solutions.

• with a list:

  A <- lapply (1 : 10, function (x) d + rnorm (3))
  

• with a matrix:

  A <- matrix (rep (d, each = 10) + rnorm (30), nrow = 10)
  

I encountered the same problem when I was trying to compile a sample project provided by Apple. In the end I figured out that apparently they pre-compiled the sample code before shipping them to developers, so the binary had their signature.

The way to solve it is simple, just delete all the built binaries and re-compile using your own bundle identifier and you should be fine.

Just go to the menu bar, click on [Product] -> [Clean Build Folder] to delete all compiled binaries

What you want to do is prevent the default action of the click event. To do this, you will need to modify your script like this:

$(document).ready(function() {
  $('.galleryicon').live("click", function(e) {

    $('#mainImage').hide();
    $('#cakebox').css('background-image', "url('ajax-loader.gif')");
    var i = $('<img />').attr('src',this.href).load(function() {
        $('#mainImage').attr('src', i.attr('src'));
        $('#cakebox').css('background-image', 'none');
        $('#mainImage').fadeIn();
    });
    return false; 
    e.preventDefault();
   });
 });

So, you're adding an "e" that represents the event in the line $('.galleryicon').live("click", function(e) { and you're adding the line e.preventDefault();

I think this approach is the right one:

public List<Class> getClasses() throws ClassNotFoundException {
    List<Class> classes;
    try {
        classes = Stream.of("java.lang.Object", "java.lang.Integer", "java.lang.String").map(className -> {
            try {
                return Class.forName(className);
            } catch (ClassNotFoundException e) {
                throw new UndeclaredThrowableException(e);
            }
        }).collect(Collectors.toList());
    } catch (UndeclaredThrowableException e) {
        if (e.getCause() instanceof ClassNotFoundException) {
            throw (ClassNotFoundException) e.getCause();
        } else {
            // this should never happen
            throw new IllegalStateException(e.getMessage(), e);
        }
    }
    return classes;
}

Wrapping the checked exception inside the Callable in a UndeclaredThrowableException (that’s the use case for this exception) and unwrapping it outside.

Yes, I find it ugly, and I would advise against using lambdas in this case and just fall back to a good old loop, unless you are working with a parallel stream and paralellization brings an objective benefit that justifies the unreadability of the code.

As many others have pointed out, there are solutions to this situation, and I hope one of them will make it into a future version of Java.

If you use the JQuery library you can use the .hover() event which merges the mouseover and mouseout event and helps you with the timing and child elements:

$(this).hover(function(){},function(){});

The first function is the start of the hover and the next is the end. Read more at: http://docs.jquery.com/Events/hover

Use list comprehension.

Short circuiting the creation of iterable using a list for example :)

>>> x = [1, 2, 3, 4]
>>> 
>>> k = x.__iter__()
>>> k
<listiterator object at 0x100517490>
>>> l = [y for y in k]
>>> l
[1, 2, 3, 4]
>>> 
>>> z = Set([1,2])
>>> z.update(l)
>>> z
set([1, 2, 3, 4])
>>> 

[Edit: missed the set part of question]

This answer is similar to Jabran Saeed's, except it handles window resizing as well. I got it from here.

constructor(props) {
  super(props);
  this.state = { width: 0, height: 0 };
  this.updateWindowDimensions = this.updateWindowDimensions.bind(this);
}

componentDidMount() {
  this.updateWindowDimensions();
  window.addEventListener('resize', this.updateWindowDimensions);
}

componentWillUnmount() {
  window.removeEventListener('resize', this.updateWindowDimensions);
}

updateWindowDimensions() {
  this.setState({ width: window.innerWidth, height: window.innerHeight });
}

For those of us who have a github.com account, but only get a nasty error message when we type "git" into the command-line, here's how to do it all in your browser :)

1. Same as Tim and Farhan wrote: Fork your own copy of the project:
2. After a few seconds, you'll be redirected to your own forked copy of the project:
3. Navigate to the file(s) you need to change and click "Edit this file" in the toolbar:
4. After editing, write a few words describing the changes and then "Commit changes", just as well to the master branch (since this is only your own copy and not the "main" project).
5. Repeat steps 3 and 4 for all files you need to edit, and then go back to the root of your copy of the project. There, click the green "Compare, review..." button:
6. Finally, click "Create pull request" ..and then "Create pull request" again after you've double-checked your request's heading and description:

I've got this error and I finally solved it with the command below.

restorecon -r /var/www/html

The issue is caused when you mv something from one place to another. It preserves the selinux context of the original when you move it, so if you untar something in /home or /tmp it gets given an selinux context that matches its location. Now you mv that to /var/www/html and it takes the context saying it belongs in /tmp or /home with it and httpd is not allowed by policy to access those files.

If you cp the files instead of mv them, the selinux context gets assigned according to the location you're copying to, not where it's coming from. Running restorecon puts the context back to its default and fixes it too.

Alternatively, manually download and execute http://www.lfd.uci.edu/~gohlke/pythonlibs Scipy version suitable for you. Consider your Python version (python --version) and your system architecture (32/64 bit). Choose the Scipy version accordingly. scipy-0.18.1-cp27-cp27m-win32 - for Python 2.7 32 bit scipy-0.18.1-cp27-cp27m-win_amd64 - for Python 2.7 64 bit Otherwise the error scipy-0.15.1-cp33-none-win_amd64.whl.whl is not supported wheel on this platform will popup on installation.

Now change directory to the downloaded file and execute command pip install scipy-0.15.1-cp33-none-win_amd64.whl.whl (change file name appropriately)

I have added this answer only because the Arun's answer(found useful by myself) has not mentioned anything about 32/64 bit matching which i have faced.

http://docs.jquery.com/Events/jQuery.Event

Try with event.target

Contains the DOM element that issued the event. This can be the element that registered for the event or a child of it.

Beware of ORDER BY RAND() because of performance and results. Check this article out: http://jan.kneschke.de/projects/mysql/order-by-rand/

We face this error when we are selecting data from more than one tables by joining tables and at least one of the selected columns (it will also happen when use * to select all columns) exist with same name in more than one tables (our selected/joined tables). In that case we must have to specify from which table we are selecting out column.

Following is a an example solution implementation of concept explained above

I think you have ambiguity only in InvoiceID that exists both in InvoiceLineItems and Invoices Other fields seem distinct. So try This

I just replace InvoiceID with Invoices.InvoiceID

   SELECT 
        VendorName, Invoices.InvoiceID, InvoiceSequence, InvoiceLineItemAmount
    FROM Vendors 
    JOIN Invoices ON (Vendors.VendorID = Invoices.VendorID)
    JOIN InvoiceLineItems ON (Invoices.InvoiceID = InvoiceLineItems.InvoiceID)
    WHERE  
        Invoices.InvoiceID IN
            (SELECT InvoiceSequence 
             FROM InvoiceLineItems
             WHERE InvoiceSequence > 1)
    ORDER BY 
        VendorName, Invoices.InvoiceID, InvoiceSequence, InvoiceLineItemAmount

You can use tablename.columnnae for all columns (in selection,where,group by and order by) without using any alias. However you can use an alias as guided by other answers

This will not work:

wget -q -S -O - google.com 1>wget.txt 2>&1

since redirects are evaluated right to left, this sends html to wget.txt and the header to STDOUT:

wget -q -S -O - google.com 2>&1 1>wget.txt

In Python 3.4 you will be able to do:

[*innerlist for innerlist in outer_list]

You are creating a set via set(...) call, and set needs hashable items. You can't have set of lists. Because list's arent hashable.

[[(a,b) for a in range(3)] for b in range(3)] is a list. It's not a hashable type. The __hash__ you saw in dir(...) isn't a method, it's just None.

A list comprehension returns a list, you don't need to explicitly use list there, just use:

>>> [[(a,b) for a in range(3)] for b in range(3)]
[[(0, 0), (1, 0), (2, 0)], [(0, 1), (1, 1), (2, 1)], [(0, 2), (1, 2), (2, 2)]]

Try those:

>>> a = {1, 2, 3}
>>> b= [1, 2, 3]
>>> type(a)
<class 'set'>
>>> type(b)
<class 'list'>
>>> {1, 2, []}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'
>>> print([].__hash__)
None
>>> [[],[],[]] #list of lists
[[], [], []]
>>> {[], [], []} #set of lists
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

The advice you were given is flawed. Unconditionally setting GIT_AUTHOR_DATE in an --env-filter would rewrite the date of every commit. Also, it would be unusual to use git commit inside --index-filter.

You are dealing with multiple, independent problems here.

Specifying Dates Other Than “now”

Each commit has two dates: the author date and the committer date. You can override each by supplying values through the environment variables GIT_AUTHOR_DATE and GIT_COMMITTER_DATE for any command that writes a new commit. See “Date Formats” in git-commit(1) or the below:

Git internal format = <unix timestamp> <time zone offset>, e.g.  1112926393 +0200
RFC 2822            = e.g. Thu, 07 Apr 2005 22:13:13 +0200
ISO 8601            = e.g. 2005-04-07T22:13:13

The only command that writes a new commit during normal use is git commit. It also has a --date option that lets you directly specify the author date. Your anticipated usage includes git filter-branch --env-filter also uses the environment variables mentioned above (these are part of the “env” after which the option is named; see “Options” in git-filter-branch(1) and the underlying “plumbing” command git-commit-tree(1).

Inserting a File Into a Single ref History

If your repository is very simple (i.e. you only have a single branch, no tags), then you can probably use git rebase to do the work.

In the following commands, use the object name (SHA-1 hash) of the commit instead of “A”. Do not forget to use one of the “date override” methods when you run git commit.

---A---B---C---o---o---o   master

git checkout master
git checkout A~0
git add path/to/file
git commit --date='whenever'
git tag ,new-commit -m'delete me later'
git checkout -
git rebase --onto ,new-commit A
git tag -d ,new-commit

---A---N                      (was ",new-commit", but we delete the tag)
        \
         B'---C'---o---o---o   master

If you wanted to update A to include the new file (instead of creating a new commit where it was added), then use git commit --amend instead of git commit. The result would look like this:

---A'---B'---C'---o---o---o   master

The above works as long as you can name the commit that should be the parent of your new commit. If you actually want your new file to be added via a new root commit (no parents), then you need something a bit different:

B---C---o---o---o   master

git checkout master
git checkout --orphan new-root
git rm -rf .
git add path/to/file
GIT_AUTHOR_DATE='whenever' git commit
git checkout -
git rebase --root --onto new-root
git branch -d new-root

N                       (was new-root, but we deleted it)
 \
  B'---C'---o---o---o   master

git checkout --orphan is relatively new (Git 1.7.2), but there are other ways of doing the same thing that work on older versions of Git.

Inserting a File Into a Multi-ref History

If your repository is more complex (i.e. it has more than one ref (branches, tags, etc.)), then you will probably need to use git filter-branch. Before using git filter-branch, you should make a backup copy of your entire repository. A simple tar archive of your entire working tree (including the .git directory) is sufficient. git filter-branch does make backup refs, but it is often easier to recover from a not-quite-right filtering by just deleting your .git directory and restoring it from your backup.

Note: The examples below use the lower-level command git update-index --add instead of git add. You could use git add, but you would first need to copy the file from some external location to the expected path (--index-filter runs its command in a temporary GIT_WORK_TREE that is empty).

If you want your new file to be added to every existing commit, then you can do this:

new_file=$(git hash-object -w path/to/file)
git filter-branch \
  --index-filter \
    'git update-index --add --cacheinfo 100644 '"$new_file"' path/to/file' \
  --tag-name-filter cat \
  -- --all
git reset --hard

I do not really see any reason to change the dates of the existing commits with --env-filter 'GIT_AUTHOR_DATE=…'. If you did use it, you would have make it conditional so that it would rewrite the date for every commit.

If you want your new file to appear only in the commits after some existing commit (“A”), then you can do this:

file_path=path/to/file
before_commit=$(git rev-parse --verify A)
file_blob=$(git hash-object -w "$file_path")
git filter-branch \
  --index-filter '

    if x=$(git rev-list -1 "$GIT_COMMIT" --not '"$before_commit"') &&
       test -n "$x"; then
         git update-index --add --cacheinfo 100644 '"$file_blob $file_path"'
    fi

  ' \
  --tag-name-filter cat \
  -- --all
git reset --hard

If you want the file to be added via a new commit that is to be inserted into the middle of your history, then you will need to generate the new commit prior to using git filter-branch and add --parent-filter to git filter-branch:

file_path=path/to/file
before_commit=$(git rev-parse --verify A)

git checkout master
git checkout "$before_commit"
git add "$file_path"
git commit --date='whenever'
new_commit=$(git rev-parse --verify HEAD)
file_blob=$(git rev-parse --verify HEAD:"$file_path")
git checkout -

git filter-branch \
  --parent-filter "sed -e s/$before_commit/$new_commit/g" \
  --index-filter '

    if x=$(git rev-list -1 "$GIT_COMMIT" --not '"$new_commit"') &&
       test -n "$x"; then
         git update-index --add --cacheinfo 100644 '"$file_blob $file_path"'
    fi

  ' \
  --tag-name-filter cat \
  -- --all
git reset --hard

You could also arrange for the file to be first added in a new root commit: create your new root commit via the “orphan” method from the git rebase section (capture it in new_commit), use the unconditional --index-filter, and a --parent-filter like "sed -e \"s/^$/-p $new_commit/\"".

I was not able to find any solution for this type of animation using ViewPropertyAnimator.

Here's an example:

Layout:

<FrameLayout
android:id="@+id/child_view_container"
android:layout_width="match_parent"
android:layout_height="wrap_content">

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/child_view"
        android:gravity="center_horizontal"
        android:layout_gravity="center_horizontal"
    />
</FrameLayout>

Animate - Right to left and exit view:

final childView = findViewById(R.id.child_view);
View containerView = findViewById(R.id.child_view_container);
childView.animate()
  .translationXBy(-containerView.getWidth())
  .setDuration(TRANSLATION_DURATION)
  .setInterpolator(new AccelerateDecelerateInterpolator())
  .setListener(new AnimatorListenerAdapter() {
    @Override
    public void onAnimationEnd(Animator animation) {
        childView.setVisibility(View.GONE);
    }
});

Animate - Right to left enter view:

final View childView = findViewById(R.id.child_view);
View containerView = findViewById(R.id.child_view_container);
childView.setTranslationX(containerView.getWidth());
childView.animate()
    .translationXBy(-containerView.getWidth())
    .setDuration(TRANSLATION_DURATION)
    .setInterpolator(new AccelerateDecelerateInterpolator())
    .setListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationStart(Animator animation) {
            childView.setVisibility(View.VISIBLE);
        }
    });

Just download Python 2.7.6 Windows Installer from the official Python download page, and launch the install package.

You cannot update UI from any other thread other than the UI thread. Use this to update thread on the UI thread.

 private void AggiornaContatore()
 {         
     if(this.lblCounter.InvokeRequired)
     {
         this.lblCounter.BeginInvoke((MethodInvoker) delegate() {this.lblCounter.Text = this.index.ToString(); ;});    
     }
     else
     {
         this.lblCounter.Text = this.index.ToString(); ;
     }
 }

Please go through this chapter and more from this book to get a clear picture about threading:

http://www.albahari.com/threading/part2.aspx#_Rich_Client_Applications

This is how you do it column-wise:

[df[col].update((df[col] - df[col].min()) / (df[col].max() - df[col].min())) for col in df.columns]

Since you've labeled the question C++, you might be interested in using boost::asio, ACE, or some other cross-platform socket library for C++ or for C. Some other cross-platform libraries may be found in the answers to C++ sockets library for cross-platform and Cross platform Networking API.

Assuming that using a third party cross-platform sockets library is not an option for you...

The header <sys/socket.h> is defined in IEEE Std. 1003.1 (POSIX), but sadly Windows is non-compliant with the POSIX standard. The MinGW compiler is a port of GCC for compiling Windows applications, and therefore does not include these POSIX system headers. If you install GCC using Cygwin, then it will include these system headers to emulate a POSIX environment on Windows. Be aware, however, that if you use Cygwin for sockets that a.) you will need to put the cygwin DLL in a place where your application can read it and b.) Cygwin headers and Windows headers don't interact very well (so if you plan on including windows.h, then you probably don't want to be including sys/socket.h).

My personal recommendation would be to download a copy of VirtualBox, download a copy of Ubuntu, install Ubuntu into VirtualBox, and then do your coding and testing on Ubuntu. Alternatively, I am told that Microsoft sells a "UNIX subsystem" and that it is pre-installed on certain higher-end editions of Windows, although I have no idea how compliant this system is (and, if it is compliant, with which edition of the UNIX standard it is compliant). Winsockets are also an option, although they can behave in subtly different ways than their POSIX counterparts, even though the signatures may be similar.

Because 'abstract' means the method is meant to be overridden and one can't override 'static' methods.

I have summarized my favorites to try out:

https://repl.it/@SmaMa/Python-List-of-unique-dictionaries

# ----------------------------------------------
# Setup
# ----------------------------------------------

myList = [
  {"id":"1", "lala": "value_1"},
  {"id": "2", "lala": "value_2"}, 
  {"id": "2", "lala": "value_2"}, 
  {"id": "3", "lala": "value_3"}
]
print("myList:", myList)

# -----------------------------------------------
# Option 1 if objects has an unique identifier
# -----------------------------------------------

myUniqueList = list({myObject['id']:myObject for myObject in myList}.values())
print("myUniqueList:", myUniqueList)

# -----------------------------------------------
# Option 2 if uniquely identified by whole object
# -----------------------------------------------

myUniqueSet = [dict(s) for s in set(frozenset(myObject.items()) for myObject in myList)]
print("myUniqueSet:", myUniqueSet)

# -----------------------------------------------
# Option 3 for hashable objects (not dicts)
# -----------------------------------------------

myHashableObjects = list(set(["1", "2", "2", "3"]))
print("myHashAbleList:", myHashableObjects)

You ca try this:

ul { list-style: none;}

li { position: relative;}

li:before {
    position: absolute;  
    top: 8px;  
    margin: 8px 0 0 -12px;    
    vertical-align: middle;
    display: inline-block;
    width: 4px;
    height: 4px;
    background: #ccc;
    content: "";
}

It worked for me, thanks to this post.

If you are trying to get the id, then please update your code like

  html += '<option id = "' + n.id + "' value="' + i + '">' + n.names + '</option>';

To retrieve id,

$('option:selected').attr("id")

To retrieve Value

$('option:selected').val()

in Javascript

var e = document.getElementById("jobSel");
var job = e.options[e.selectedIndex].value;

This example might help you. by using simple casting you can get code behind urdu character.

string str = "?????";
        char ch = ' ';
        int number = 0;
        for (int i = 0; i < str.Length; i++)
        {
            ch = str[i];
            number = (int)ch;
            Console.WriteLine(number);
        }

multiprocessing.Pool - PicklingError: Can't pickle <type 'thread.lock'>: attribute lookup thread.lock failed

Move the queue to self instead of as an argument to your functions package and send

This worked for me

mongod --port 27017 --dbpath C:\MongoDB\data\db

There should be svn utility on you box, if installed:

$ svn checkout http://example.com/svn/somerepo somerepo

This will check out a working copy from a specified repository to a directory somerepo on our file system.

You may want to print commands, supported by this utility:

$ svn help

uname -a output in your question is identical to one, used by Parallels Virtuozzo Containers for Linux 4.0 kernel, which is based on Red Hat 5 kernel, thus your friends are rpm or the following command:

$ sudo yum install subversion

You may define your enum like so and use cast where needed

public enum MyEnum
{
    VariablePeriods = 1,
    FixedPeriods = 2
}

Usage

public class Entity
{
    public MyEnum Property { get; set; }
}

var returnedFromDB = 1;
var entity = new Entity();
entity.Property = (MyEnum)returnedFromDB;

Is this markup added to the DOM asynchronously? You will need to use live in that case:

NOTE: .live has been deprecated and removed in the latest versions of jQuery (for good reason). Please refer to the event delegation strategy below for usage and solution.

<script>
    $(document).ready(function(){
        $('.play_navigation a').live('click', function(){
            console.log("this is the click");
            return false;
        });
    });
</script>

The fact that you are able to re-run your script block and have it work tells me that for some reason the elements weren't available at the time of binding or the binding was removed at some point. If the elements weren't there at bind-time, you will need to use live (or event delegation, preferably). Otherwise, you need to check your code for something else that would be removing the binding.

Using jQuery 1.7 event delegation:

$(function () {

    $('.play_navigation').on('click', 'a', function (e) {
        console.log('this is the click');
        e.preventDefault();
    });

});

You can also delegate events up to the document if you feel that you would like to bind the event before the document is ready (note that this also causes jQuery to examine every click event to determine if the element matches the appropriate selector):

$(document).on('click', '.play_navigation a', function (e) {
    console.log('this is the click');
    e.preventDefault();
});

You can build an CustButton with TouchableWithoutFeedback, and set the effect and logic you want with onPressIn, onPressout or other props.

Try this:

if(myString != "-1")

The opperand is != and not =!

You can also use Equals

if(!myString.Equals("-1"))

Note the ! before myString

for those stumbling upon this question: the python jsonlines library (much younger than this question) elegantly handles files with one json document per line. see https://jsonlines.readthedocs.io/

• You can use copy con to write a long text

• Example:

  C:\COPY CON [drive:][path][File name]

  .... Content

  F6

  1 file(s) is copied

The answer by Tatu is how I would intuitively do it, but I have experienced some problems in Internet Explorer with this way of nesting/binding the events, even though it is done through the .on() method.

I havn't been able to pinpoint exactly which versions of jQuery this is the problem with. But I sometimes see the problem in the following versions:

• 2.0.2
• 1.10.1
• 1.6.4
• Mobile 1.3.0b1
• Mobile 1.4.2
• Mobile 1.2.0

My workaround have been to first define the function,

function myFunction() {
    ...
}

and then handle the events individually

// Call individually due to IE not handling binds properly
$(window).on("scroll", myFunction);
$(window).on("resize", myFunction);

This is not the prettiest solution, but it works for me, and I thought I would put it out there to help others that might stumble upon this issue

Sign-off is a requirement for getting patches into the Linux kernel and a few other projects, but most projects don't actually use it.

It was introduced in the wake of the SCO lawsuit, (and other accusations of copyright infringement from SCO, most of which they never actually took to court), as a Developers Certificate of Origin. It is used to say that you certify that you have created the patch in question, or that you certify that to the best of your knowledge, it was created under an appropriate open-source license, or that it has been provided to you by someone else under those terms. This can help establish a chain of people who take responsibility for the copyright status of the code in question, to help ensure that copyrighted code not released under an appropriate free software (open source) license is not included in the kernel.

Change the directory of the Project and re-open.

From the python command prompt:

import scipy
print scipy.__version__

In python 3 you'll need to change it to:

print (scipy.__version__)

struct Node {
    int i;
    int j;
};
struct Node a, *p = &a;

Here the to access the values of i and j we can use the variable a and the pointer p as follows: a.i, (*p).i and p->i are all the same.

Here . is a "Direct Selector" and -> is an "Indirect Selector".

You can use MarkerWithLabel with SVG icons.

Update: The Google Maps Javascript API v3 now natively supports multiple characters in the MarkerLabel

proof of concept fiddle (you didn't provide your icon, so I made one up)

Note: there is an issue with labels on overlapping markers that is addressed by this fix, credit to robd who brought it up in the comments.

You can't have two elements with the same ID.

Aside from that, you are defining them as block elemnts, meaning (in layman's terms) that they are being forced to appear on their own line.

Instead, try something like this:

<div class="link"><a href="..."><img src="..."... /></a></div>
<div class="link"><a href="..."><img src="..."... /></a></div>

CSS:

.link {
    width: 50%;
    float: left;
    text-align: center;
}

Depending on the libc release it could be needed to set both SO_REUSEADDR and SO_REUSEPORT socket options as explained in socket(7) documentation :

   SO_REUSEPORT (since Linux 3.9)
          Permits multiple AF_INET or AF_INET6 sockets to be bound to an
          identical socket address.  This option must be set on each
          socket (including the first socket) prior to calling bind(2)
          on the socket.  To prevent port hijacking, all of the
          processes binding to the same address must have the same
          effective UID.  This option can be employed with both TCP and
          UDP sockets.

As this socket option appears with kernel 3.9 and raspberry use 3.12.x, it will be needed to set SO_REUSEPORT.

You can set theses two options before calling bind like this :

    int reuse = 1;
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, (const char*)&reuse, sizeof(reuse)) < 0)
        perror("setsockopt(SO_REUSEADDR) failed");

#ifdef SO_REUSEPORT
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEPORT, (const char*)&reuse, sizeof(reuse)) < 0) 
        perror("setsockopt(SO_REUSEPORT) failed");
#endif

You might want to take a look at a similar question posted on Stack Overflow. It uses the .apply() method to accomplish this.

start "" "%SYSTEMDRIVE%\Program Files (x86)\Git\bin\sh.exe" --login -i

Git bash will get open.

Add the below code from the resources tags in your pom.xml inside build tags. so it means resources tags must be inside of build tags in your pom.xml

<build>
    <resources>
        <resource>
            <directory>src/main/java/resources</directory>
                <filtering>true</filtering> 
         </resource>
     </resources>
<build/>

If you define your function to take argument of std::vector<int>& arr and integer value, then you can use push_back inside that function:

void do_something(int el, std::vector<int>& arr)
{
    arr.push_back(el);
    //....
}

usage:

std::vector<int> arr;
do_something(1, arr); 

import org.apache.commons.lang.StringUtils;

String Utils

Use:

StringUtils.indexOfAny(inputString, new String[]{item1, item2, item3})

It will return the index of the string found or -1 if none is found.

Here's a nice little global function you can add for a nicer syntax:

func dispatch_on_main(block: dispatch_block_t) {
    dispatch_async(dispatch_get_main_queue(), block)
}

And usage

dispatch_on_main {
    // Do some UI stuff
}

The msg['To'] needs to be a string:

msg['To'] = "[email protected], [email protected], [email protected]"

While the recipients in sendmail(sender, recipients, message) needs to be a list:

sendmail("[email protected]", ["[email protected]", "[email protected]", "[email protected]"], "Howdy")

Try this:

Go into Settings (File > Settings or ctrl+alt+S). Under Project Settings, select the "Compiler" node. On the left, uncheck "Clear output directory on rebuild".

Note that this is a per project setting. If desired, change it in the project template settigs (Settings > Other Settings > Template Settings).

Use css text-transform to display text in all input type text. In Jquery you can then transform the value to uppercase on blur event.

Css:

input[type=text] {
    text-transform: uppercase;
}

Jquery:

$(document).on('blur', "input[type=text]", function () {
    $(this).val(function (_, val) {
        return val.toUpperCase();
    });
});

final class MySingleton {
     private init() {}
     static let shared = MySingleton()
}

Then call it;

let shared = MySingleton.shared

Regarding this part:

When I convert it to UTF-8 without bom and close file, the file is again ANSI when I reopen.

The easiest solution is to avoid the problem entirely by properly configuring Notepad++.

Try Settings -> Preferences -> New document -> Encoding -> choose UTF-8 without BOM, and check Apply to opened ANSI files.

That way all the opened ANSI files will be treated as UTF-8 without BOM.

For explanation what's going on, read the comments below this answer.

To fully learn about Unicode and UTF-8, read this excellent article from Joel Spolsky.

The view-source url prefix trick didn't work for me using chrome on an iphone. There are apps I could have installed to do this I guess but for whatever reason I just preferred to do it myself rather than install 'yet another app'.

I found this nice quick tutorial for how to setup a bookmark on mobile safari that will automatically open the view source of a page: https://appletoolbox.com/2014/03/how-to-view-webpage-html-source-codes-on-ipad-iphone-no-app-required/

It worked flawlessly for me and now I have it set as a permanent bookmark any time I want, with no app installed.

Edit: There are basically 6 steps which should work for either Chrome or Safari. Instructions for Safari are:

1. Open Safari and browse to an arbitrary page.
2. Select the "Share" (or action") button in Safari (looks like a square with an arrow coming out of the top).
3. Select "Add Bookmark"
4. Delete the page title and replace it with something useful like "Show Page Source". Click Save.
5. Next browse to this exact Stack Overflow answer on your phone and copy the javascript code below to your phone clipboard (code credit: Rob Flaherty):

javascript:(function(){var a=window.open('about:blank').document;a.write('<!DOCTYPE html><html><head><title>Source of '+location.href+'</title><meta name="viewport" content="width=device-width" /></head><body></body></html>');a.close();var b=a.body.appendChild(a.createElement('pre'));b.style.overflow='auto';b.style.whiteSpace='pre-wrap';b.appendChild(a.createTextNode(document.documentElement.innerHTML))})();

6. Open the "Bookmarks" in Safari and opt to Edit the newly created Show Page Source bookmark. Delete whatever was previously saved in the Address field and instead paste in the Javascript code. Save it.
7. (Optional) Profit!

import re

url = '<p>Hello World</p><a href="http://example.com">More Examples</a><a href="http://example2.com">Even More Examples</a>'

urls = re.findall('https?://(?:[-\w.]|(?:%[\da-fA-F]{2}))+', url)

>>> print urls

Place the following in your jQuery mouseover event handler:

$(this).css('color', 'red');

To set both color and size at the same time:

$(this).css({ 'color': 'red', 'font-size': '150%' });

You can set any CSS attribute using the .css() jQuery function.

Update June 2017 (from VSCode 1.14)

The ability to merge local branches has been added through PR 25731 and commit 89cd05f: accessible through the "Git: merge branch" command.
And PR 27405 added handling the diff3-style merge correctly.

Vahid's answer mention 1.17, but that September release actually added nothing regarding merge.
Only the 1.18 October one added Git conflict markers

From 1.18, with the combination of merge command (1.14) and merge markers (1.18), you truly can do local merges between branches.

Original answer 2016:

The Version Control doc does not mention merge commands, only merge status and conflict support.

Even the latest 1.3 June release does not bring anything new to the VCS front.

This is supported by issue 5770 which confirms you cannot use VS Code as a git mergetool, because:

Is this feature being included in the next iteration, by any chance?

Probably not, this is a big endeavour, since a merge UI needs to be implemented.

That leaves the actual merge to be initiated from command line only.

Looking at my system's menu.vim (look for 'Color Scheme submenu') and @chappar's answer, I came up with the following function:

" Returns the list of available color schemes
function! GetColorSchemes()
   return uniq(sort(map(
   \  globpath(&runtimepath, "colors/*.vim", 0, 1),  
   \  'fnamemodify(v:val, ":t:r")'
   \)))
endfunction

It does the following:

1. Gets the list of available color scheme scripts under all runtime paths (globpath, runtimepath)
2. Maps the script paths to their base names (strips parent dirs and extension) (map, fnamemodify)
3. Sorts and removes duplicates (uniq, sort)

Then to use the function I do something like this:

let s:schemes = GetColorSchemes()
if index(s:schemes, 'solarized') >= 0
   colorscheme solarized
elseif index(s:schemes, 'darkblue') >= 0
   colorscheme darkblue
endif

Which means I prefer the 'solarized' and then the 'darkblue' schemes; if none of them is available, do nothing.

How about subclassing json.JSONEncoder?

class DecimalEncoder(json.JSONEncoder):
    def default(self, o):
        if isinstance(o, decimal.Decimal):
            # wanted a simple yield str(o) in the next line,
            # but that would mean a yield on the line with super(...),
            # which wouldn't work (see my comment below), so...
            return (str(o) for o in [o])
        return super(DecimalEncoder, self).default(o)

Then use it like so:

json.dumps({'x': decimal.Decimal('5.5')}, cls=DecimalEncoder)

Of course the answers above all do the job, but still i would like to use something like

gradle run path1 path2

well this can't be done, but what if we can:

gralde run --- path1 path2

If you think it is more elegant, then you can do it, the trick is to process the command line and modify it before gradle does, this can be done by using init scripts

The init script below:

1. Process the command line and remove --- and all other arguments following '---'
2. Add property 'appArgs' to gradle.ext

So in your run task (or JavaExec, Exec) you can:

if (project.gradle.hasProperty("appArgs")) {
                List<String> appArgs = project.gradle.appArgs;

                args appArgs

 }

The init script is:

import org.gradle.api.invocation.Gradle

Gradle aGradle = gradle

StartParameter startParameter = aGradle.startParameter

List tasks = startParameter.getTaskRequests();

List<String> appArgs = new ArrayList<>()

tasks.forEach {
   List<String> args = it.getArgs();


   Iterator<String> argsI = args.iterator();

   while (argsI.hasNext()) {

      String arg = argsI.next();

      // remove '---' and all that follow
      if (arg == "---") {
         argsI.remove();

         while (argsI.hasNext()) {

            arg = argsI.next();

            // and add it to appArgs
            appArgs.add(arg);

            argsI.remove();

        }
    }
}

}


   aGradle.ext.appArgs = appArgs

Limitations:

1. I was forced to use '---' and not '--'
2. You have to add some global init script

If you don't like global init script, you can specify it in command line

gradle -I init.gradle run --- f:/temp/x.xml

Or better add an alias to your shell:

gradleapp run --- f:/temp/x.xml

Below settings are worked well for me,

"editor.insertSpaces": false,
"editor.formatOnSave": true, // only if you want auto fomattting on saving the file
"editor.detectIndentation": false

Above settings will reflect and applied to every files. You don't need to indent/format every file manually.

I have solved it as follow.

import $ from 'jquery';

(function () {
    // ... code let script = $(..)
})();

you can use :

Process.GetCurrentProcess().MainWindowHandle

The below query takes the first date for each work order (in a table of showing all status changes):

SELECT
    WORKORDERNUM,
    MIN(DATE)
FROM
    WORKORDERS
WHERE
    DATE >= to_date('2015-01-01','YYYY-MM-DD')
GROUP BY
    WORKORDERNUM

That method can't return true. That's the point of Long.MAX_VALUE. It would be really confusing if its name were... false. Then it should be just called Long.SOME_FAIRLY_LARGE_VALUE and have literally zero reasonable uses. Just use Android's isUserAGoat, or you may roll your own function that always returns false.

Note that a long in memory takes a fixed number of bytes. From Oracle:

long: The long data type is a 64-bit signed two's complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). Use this data type when you need a range of values wider than those provided by int.

As you may know from basic computer science or discrete math, there are 2^64 possible values for a long, since it is 64 bits. And as you know from discrete math or number theory or common sense, if there's only finitely many possibilities, one of them has to be the largest. That would be Long.MAX_VALUE. So you are asking something similar to "is there an integer that's >0 and < 1?" Mathematically nonsensical.

If you actually need this for something for real then use BigInteger class.

Because if you create a reference to a variable, all names for that variable (including the original) BECOME REFERENCES.

In isolation, there is nothing wrong with using for-in on arrays. For-in iterates over the property names of an object, and in the case of an "out-of-the-box" array, the properties corresponds to the array indexes. (The built-in propertes like length, toString and so on are not included in the iteration.)

However, if your code (or the framework you are using) add custom properties to arrays or to the array prototype, then these properties will be included in the iteration, which is probably not what you want.

Some JS frameworks, like Prototype modifies the Array prototype. Other frameworks like JQuery doesn't, so with JQuery you can safely use for-in.

If you are in doubt, you probably shouldn't use for-in.

An alternative way of iterating through an array is using a for-loop:

for (var ix=0;ix<arr.length;ix++) alert(ix);

However, this have a different issue. The issue is that a JavaScript array can have "holes". If you define arr as:

var arr = ["hello"];
arr[100] = "goodbye";

Then the array have two items, but a length of 101. Using for-in will yield two indexes, while the for-loop will yield 101 indexes, where the 99 has a value of undefined.

An ES6 update... though both filter and map might need customization.

Object.entries(theObj) returns a [[key, value],] array representation of an object that can be worked on using Javascript's array methods, .each(), .any(), .forEach(), .filter(), .map(), .reduce(), etc.

Saves a ton of work on iterating over parts of an object Object.keys(theObj), or Object.values() separately.

TCP/IP is a stream-based protocol, not a message-based protocol. There's no guarantee that every send() call by one peer results in a single recv() call by the other peer receiving the exact data sent—it might receive the data piece-meal, split across multiple recv() calls, due to packet fragmentation.

You need to define your own message-based protocol on top of TCP in order to differentiate message boundaries. Then, to read a message, you continue to call recv() until you've read an entire message or an error occurs.

One simple way of sending a message is to prefix each message with its length. Then to read a message, you first read the length, then you read that many bytes. Here's how you might do that:

def send_msg(sock, msg):
    # Prefix each message with a 4-byte length (network byte order)
    msg = struct.pack('>I', len(msg)) + msg
    sock.sendall(msg)

def recv_msg(sock):
    # Read message length and unpack it into an integer
    raw_msglen = recvall(sock, 4)
    if not raw_msglen:
        return None
    msglen = struct.unpack('>I', raw_msglen)[0]
    # Read the message data
    return recvall(sock, msglen)

def recvall(sock, n):
    # Helper function to recv n bytes or return None if EOF is hit
    data = bytearray()
    while len(data) < n:
        packet = sock.recv(n - len(data))
        if not packet:
            return None
        data.extend(packet)
    return data

Then you can use the send_msg and recv_msg functions to send and receive whole messages, and they won't have any problems with packets being split or coalesced on the network level.

tl;dr

Use only modern java.time classes. Never use the terrible legacy classes such as SimpleDateFormat, Date, or java.sql.Timestamp.

ZonedDateTime                    // Represent a moment as perceived in the wall-clock time used by the people of a particular region ( a time zone).
.now(                            // Capture the current moment.
    ZoneId.of( "Africa/Tunis" )  // Specify the time zone using proper Continent/Region name. Never use 3-4 character pseudo-zones such as PDT, EST, IST. 
)                                // Returns a `ZonedDateTime` object. 
.format(                         // Generate a `String` object containing text representing the value of our date-time object. 
    DateTimeFormatter.ofPattern( "uuuu.MM.dd.HH.mm.ss" )
)                                // Returns a `String`. 

Or use the JVM’s current default time zone.

ZonedDateTime
.now( ZoneId.systemDefault() )
.format( DateTimeFormatter.ofPattern( "uuuu.MM.dd.HH.mm.ss" ) )

java.time & JDBC 4.2

The modern approach uses the java.time classes as seen above.

If your JDBC driver complies with JDBC 4.2, you can directly exchange java.time objects with the database. Use PreparedStatement::setObject and ResultSet::getObject.

Use java.sql only for drivers before JDBC 4.2

If your JDBC driver does not yet comply with JDBC 4.2 for support of java.time types, you must fall back to using the java.sql classes.

Storing data.

OffsetDateTime odt = OffsetDateTime.now( ZoneOffset.UTC ) ;  // Capture the current moment in UTC.
myPreparedStatement.setObject( … , odt ) ;

Retrieving data.

OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;

The java.sql types, such as java.sql.Timestamp, should only be used for transfer in and out of the database. Immediately convert to java.time types in Java 8 and later.

java.time.Instant

A java.sql.Timestamp maps to a java.time.Instant, a moment on the timeline in UTC. Notice the new conversion method toInstant added to the old class.

java.sql.Timestamp ts = myResultSet.getTimestamp( … );
Instant instant = ts.toInstant(); 

Time Zone

Apply the desired/expected time zone (ZoneId) to get a ZonedDateTime.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

Formatted Strings

Use a DateTimeFormatter to generate your string. The pattern codes are similar to those of java.text.SimpleDateFormat but not exactly, so read the doc carefully.

DateTimeFormatter formatter = DateTimeFormatter.ofPattern( "uuuu.MM.dd.HH.mm.ss" );
String output = zdt.format( formatter );

This particular format is ambiguous as to its exact meaning as it lacks any indication of offset-from-UTC or time zone.

ISO 8601

If you have any say in the matter, I suggest you consider using standard ISO 8601 formats rather than rolling your own. The standard format is quite similar to yours. For example:
2016-02-20T03:26:32+05:30.

The java.time classes use these standard formats by default, so no need to specify a pattern. The ZonedDateTime class extends the standard format by appending the name of the time zone (a wise improvement).

String output = zdt.toString(); // Example: 2007-12-03T10:15:30+01:00[Europe/Paris]

Convert to java.sql

You can convert from java.time back to java.sql.Timestamp. Extract an Instant from the ZonedDateTime.

New methods have been added to the old classes to facilitate converting to/from java.time classes.

java.sql.Timestamp ts = java.sql.Timestamp.from( zdt.toInstant() );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
• Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
• Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
• Later versions of Android bundle implementations of the java.time classes.
• For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

This link contains a good checklist why core dumps are not generated:

• The core would have been larger than the current limit.
• You don't have the necessary permissions to dump core (directory and file). Notice that core dumps are placed in the dumping process' current directory which could be different from the parent process.
• Verify that the file system is writeable and have sufficient free space.
• If a sub directory named core exist in the working directory no core will be dumped.
• If a file named core already exist but has multiple hard links the kernel will not dump core.
• Verify the permissions on the executable, if the executable has the suid or sgid bit enabled core dumps will by default be disabled. The same will be the case if you have execute permissions but no read permissions on the file.
• Verify that the process has not changed working directory, core size limit, or dumpable flag.
• Some kernel versions cannot dump processes with shared address space (AKA threads). Newer kernel versions can dump such processes but will append the pid to the file name.
• The executable could be in a non-standard format not supporting core dumps. Each executable format must implement a core dump routine.
• The segmentation fault could actually be a kernel Oops, check the system logs for any Oops messages.
• The application called exit() instead of using the core dump handler.

There isn't really a way to edit files in-place. What you usually do when you can get away with it (i.e. if the files are not too big) is, you read the file into memory (File.read), perform your substitutions on the read string (String#gsub) and then write the changed string back to the file (File.open, File#write).

If the files are big enough for that to be unfeasible, what you need to do, is read the file in chunks (if the pattern you want to replace won't span multiple lines then one chunk usually means one line - you can use File.foreach to read a file line by line), and for each chunk perform the substitution on it and append it to a temporary file. When you're done iterating over the source file, you close it and use FileUtils.mv to overwrite it with the temporary file.

You want the php function "asort":

http://php.net/manual/en/function.asort.php

it sorts the array, maintaining the index associations.

Edit: I've just noticed you're using a standard array (non-associative). if you're not fussed about preserving index associations, use sort():

http://php.net/manual/en/function.sort.php

Have you checked/changed the updatePolicy settings for your repositories in your settings.xml.

This element specifies how often updates should attempt to occur. Maven will compare the local POM's timestamp (stored in a repository's maven-metadata file) to the remote. The choices are: always, daily (default), interval:X (where X is an integer in minutes) or never.

Try to set it to always.

You can try this with by adding backticks on whole url

style={{backgroundImage:url(${val.image || 'http://max-themes.net/demos/grandtour/upload/Tokyo_Dollarphotoclub_72848283-copy-700x466.jpg'} ) }}

Normally, $PYTHONPATH is used to teach python interpreter to find necessary modules. PyCharm needs to add the path in Preference.

For anyone who lands here and all the other solutions did not work give this a try. I am using typescript + react and my problem was that I was associating the files in vscode as javascriptreact not typescriptreact so check your settings for the following entries.

   "files.associations": {
    "*.tsx": "typescriptreact",
    "*.ts": "typescriptreact"
  },

I'm not familiar with the Python API but you can always use

SELECT * FROM sqlite_master;

I know this is an old question, but I've just had the same frustrating issue for a couple of hours and wanted to share my solution. In my case the option "Managements Tools" wasn't available in the installation menu either. It wasn't just greyed out as disabled or already installed, but instead just missing, it wasn't anywhere on the menu.

So what finally worked for me was to use the Web Platform Installer 4.0, and check this for installation: Products > Database > "Sql Server 2008 R2 Management Objects". Once this is done, you can relaunch the installation and "Management Tools" will appear like previous answers stated.

Note there could also be a "Sql Server 2012 Shared Management Objects", but I think this is for different purposes.

Hope this saves someone the couple of hours I wasted into this.

The ruby oneliner inspired me to try with python.

Say we want a command that indents whatever is in the clipboard with 4 spaces. Perfect for sharing snippets on stackoverflow.

$ pbpaste | python -c "import sys
 for line in sys.stdin:
   print(f'    {line}')" | pbcopy

that's not a typo. Python needs newlines to do a for loop. We want to alter the lines in one pass to avoid building up an extra array in memory.

If you don't mind building the extra array try:

$ pbpaste | python -c "import sys; print(''.join([f'    {l}' for l in sys.stdin]))" | pbcopy

but honestly awk is better for this than python. I defined this alias in my ~/.bashrc file

alias indent="pbpaste | awk '{print \"    \"\$0}' | pbcopy"

now when I run indent whatever is in my clipboard is indented.

In Java 8 that parameter is commonly used to print a warning message like this one:

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0

The reason why you get this message in Java 8 is because Permgen has been replaced by Metaspace to address some of PermGen's drawbacks (as you were able to see for yourself, one of those drawbacks is that it had a fixed size).

FYI: an article on Metaspace: http://java-latte.blogspot.in/2014/03/metaspace-in-java-8.html

I got this error after change a loop in my program, let`s see:

for ...
  for ... 
     x_batch.append(one_hot(int_word, vocab_size))
     y_batch.append(one_hot(int_nb, vocab_size, value))
  ...
  ...
  if ...
        x_batch = np.asarray(x_batch)
        y_batch = np.asarray(y_batch)
...

In fact, I was reusing the variable and forgot to reset them inside the external loop, like the comment of John Lyon:

for ...
  x_batch = []
  y_batch = []
  for ... 
     x_batch.append(one_hot(int_word, vocab_size))
     y_batch.append(one_hot(int_nb, vocab_size, value))
  ...
  ...
  if ...
        x_batch = np.asarray(x_batch)
        y_batch = np.asarray(y_batch)
...

Then, check if you are using np.asarray() or something like that.

You can do the following, when your current directory is parent_directory:

for d in [0-9][0-9][0-9]
do
    ( cd "$d" && your-command-here )
done

The ( and ) create a subshell, so the current directory isn't changed in the main script.

Try to show the pop like below

findViewById(R.id.main_layout).post(new Runnable() {
        public void run() {
            mPopupWindow.showAtLocation(findViewById(R.id.main_layout), Gravity.CENTER, 0, 0);
            Button close = (Button) customView.findViewById(R.id.btn_ok);
            close.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    mPopupWindow.dismiss();
                    doOtherStuff();
                }
            });
        }
    });

This is a circle shape with icon inside:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ok_icon"/>
    <item>
        <shape
                android:shape="oval">
            <solid android:color="@color/transparent"/>
            <stroke android:width="2dp" android:color="@color/button_grey"/>
        </shape>
    </item>
</layer-list>

Instead of turn off the csrf protection, it's better to add the following line of code into the form

<%= tag(:input, :type => "hidden", :name => request_forgery_protection_token.to_s, :value => form_authenticity_token) %> 

and if you're using form_for or form_tag to generate the form, then it will automatically add the above line of code in the form

You'll need to write an insert trigger, and possible an update trigger if you want it to change when the record is changed. This article explains it quite nicely:

http://www.revsys.com/blog/2006/aug/04/automatically-updating-a-timestamp-column-in-postgresql/

CREATE OR REPLACE FUNCTION update_modified_column()   
RETURNS TRIGGER AS $$
BEGIN
    NEW.modified = now();
    RETURN NEW;   
END;
$$ language 'plpgsql';

Apply the trigger like this:

CREATE TRIGGER update_customer_modtime BEFORE UPDATE ON customer FOR EACH ROW EXECUTE PROCEDURE  update_modified_column();

You can do the following:

String [] strings = new String [] {"1", "2" };
List<String> stringList = new ArrayList<String>(Arrays.asList(strings)); //new ArrayList is only needed if you absolutely need an ArrayList

I did like this :

public static class JsonExtension
{
    public static string ToJson(this object value)
    {
        var settings = new JsonSerializerSettings
        {
            ContractResolver = new CamelCasePropertyNamesContractResolver(),
            NullValueHandling = NullValueHandling.Ignore,
            ReferenceLoopHandling = ReferenceLoopHandling.Serialize
        };
        return JsonConvert.SerializeObject(value, settings);
    }
}

this a simple extension method in MVC core , it's going to give the ToJson() ability to every object in your project , In my opinion in a MVC project most of object should have the ability to become json ,off course it depends :)

For my framework I was using an Xcode subproject added as a git submodule.

I believe I was getting this error because I was signing the framework with a different signing Team than my main app. (switched teams for app; forgot to switch for framework)

Solution is to not sign within the framework project. Instead, in the main app's Target > General > Frameworks, Libraries, and Embedded Content section, sign the framework via Embed & Sign.

If I select Do not Embed or Embed Without Signing I instead get the error:

FRAMEWORK not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.

This should work, I think...

ResultSet results = st.executeQuery(sql);

if(results.next()) { //there is a row
 int id = results.getInt(1); //ID if its 1st column
 String str1 = results.getString(2);
 ...
}

Webkit is an HTML rendering engine used by Chrome and Safari.

It supports a number of custom CSS properties that are prefixed by -webkit-.

In case you develop applications for Android you should try out the TimingLogger class.
Take a look at these articles describing the usage of the TimingLogger helper class:

• Measuring performance in the Android SDK (27.09.2010)
• Discovering the Android API - Part 1 (03.01.2017)

<input type = "button" style ="background-color:green"/>

This is the easiest and simple way ever exist on the internet... First of all, add this permission to your manifest file...

1. "INTERNET"

2. "ACCESS_NETWORK_STATE"

add this in onCreate file of Activity..

    getPublicIP();

Now Add this function to your MainActivity.class.

    private void getPublicIP() {_x000D_

Yep it is here, using _.reduce

var params = [
    { name: 'foo', input: 'bar' },
    { name: 'baz', input: 'zle' }
];

_.reduce(params , function(obj,param) {
 obj[param.name] = param.input
 return obj;
}, {});

const getData = () => {
// some functionality
}

const that = this;
   setTimeout(() => {
   // write your functions    
   that.getData()
},6000);

Simple, Settimout function get triggered after 6000 milliseonds

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

To anyone else looking for this, I wasn't able to use certutil -importpfx into a specific store, and I didn't want to download the importpfx tool supplied by jaspernygaard's answer in order to avoid the requirement of copying the file to a large number of servers. I ended up finding my answer in a powershell script shown here.

The code uses System.Security.Cryptography.X509Certificates to import the certificate and then moves it into the desired store:

function Import-PfxCertificate { 

    param([String]$certPath,[String]$certRootStore = “localmachine”,[String]$certStore = “My”,$pfxPass = $null) 
    $pfx = new-object System.Security.Cryptography.X509Certificates.X509Certificate2 

    if ($pfxPass -eq $null) 
    {
        $pfxPass = read-host "Password" -assecurestring
    } 

    $pfx.import($certPath,$pfxPass,"Exportable,PersistKeySet") 

    $store = new-object System.Security.Cryptography.X509Certificates.X509Store($certStore,$certRootStore) 
    $store.open("MaxAllowed") 
    $store.add($pfx) 
    $store.close() 
}

Distinct and the aggregation framework are not inter-operable.

Instead you just want:

db.zips.aggregate([ 
    {$group:{_id:{city:'$city', state:'$state'}, numberOfzipcodes:{$sum:1}}}, 
    {$sort:{numberOfzipcodes:-1}},
    {$group:{_id:'$_id.state', city:{$first:'$_id.city'}, 
              numberOfzipcode:{$first:'$numberOfzipcodes'}}}
]);

In WebStart and the new 6u10 PlugIn you can use the FileOpenService, even without security permissions. For obvious reasons, you only get the file contents, not the file path.

Based on this answer by apenwarr and this comment by Miral I came up with the following solution which saved me nearly 94% of disk space when cloning the linux git repository locally while only wanting one Documentation subdirectory:

$ cd linux
$ du -sh .git .
2.1G    .git
894M    .
$ du -sh 
2.9G    .
$ mkdir ../linux-sparse-test
$ cd ../linux-sparse-test
$ git init
Initialized empty Git repository in /…/linux-sparse-test/.git/
$ git config core.sparseCheckout true
$ git remote add origin ../linux
# Parameter "origin master" saves a tiny bit if there are other branches
$ git fetch --depth=1 origin master
remote: Enumerating objects: 65839, done.
remote: Counting objects: 100% (65839/65839), done.

From ../linux

$ echo "Documentation/hid/*" > .git/info/sparse-checkout
$ git checkout master
Branch 'master' set up to track remote branch 'master' from 'origin'.

$  du -sh .git .

100K    .
$  du -sh
182M    .

So I got down from 2.9GB to 182MB which is already quiet nice.

I though didn't get this to work with git clone --depth 1 --no-checkout --filter=blob:none file:///…/linux linux-sparse-test (hinted here) as then the missing files were all added as removed files to the index. So if anyone knows the equivalent of git clone --filter=blob:none for git fetch, we can probably save some more megabytes. (Reading the man page of git-rev-list also hints that there is something like --filter=sparse:path=…, but I didn't get that to work either.

(All tried with git 2.20.1 from Debian Buster.)

try following js code

location = '..'

When you are using the wordpress prepare line, the above solutions do not work. This is the solution I used:

   $Table_Name    = $wpdb->prefix.'tablename';
   $SearchField = '%'. $YourVariable . '%';   
   $sql_query     = $wpdb->prepare("SELECT * FROM $Table_Name WHERE ColumnName LIKE %s", $SearchField) ;
 $rows = $wpdb->get_results($sql_query, ARRAY_A);

This generic solution should work on all rooted devices:

 adb shell "su -c cat /data/data/com.android.providers.contacts/databases/contacts2.db" > contacts2.d

The command connects as shell, then executes cat as root and collects the output into a local file.

In opposite to @guest-418 s solution, one does not have to dig for the user in question.

Plus If you get greedy and want all the db's at once (eg. for backup)

for i in `adb shell "su -c find /data -name '*.db'"`; do
    mkdir -p ".`dirname $i`"
    adb shell "su -c cat $i" > ".$i" 
done

This adds a mysteryous question mark to the end of the filename, but it is still readable.

Combine Kim's answer with os:

p=Path(os.getcwd())
os.chdir(p.parent)

You need the PDF Reference manual to start reading about the details and structure of PDF files. I suggest to start with version 1.7.

On windows I used a free tool PDF Analyzer to see the internal structure of PDF files. This will help in your understanding when reading the reference manual.

(I'm affiliated with PDF Analyzer, no intention to promote)

The way to do this is near the top of the man page

grep -i -A 10 'error data'

span.middle {
    margin: 0 10px 0 10px; /*top right bottom left */
}

<span>text</span> <span class="middle">text</span> <span>text</span>

Use Enum.Parse().

var content = (ContentEnum)Enum.Parse(typeof(ContentEnum), fileContentMessage);

Using the new FormData object (and other ES6 stuff), you can do this to turn your entire form into JSON:

let data = {};
let formdata = new FormData(theform);
for (let tuple of formdata.entries()) data[tuple[0]] = tuple[1];

and then just xhr.send(JSON.stringify(data)); like in Jan's original answer.

DEMO: http://jsfiddle.net/kF2uK/2/

function buttonState(){
    $("input").each(function(){
        $('#register').attr('disabled', 'disabled');
        if($(this).val() == "" ) return false;
        $('#register').attr('disabled', '');
    })
}

$(function(){
    $('#register').attr('disabled', 'disabled');
    $('input').change(buttonState);
})

For ansible, and using hyphen, this worked for me:

    - name: free-ud-ssd-space-in-percent
      debug:
        var: clusterInfo.json.content["free-ud-ssd-space-in-percent"]

Its so simple to get logs in React-Native

Use console.log and console.warn

console.log('character', parameter)

console.warn('character', parameter)

This log you can view in browser console. If you want to check device log or say production APK log you can use

adb logcat

adb -d logcat

import java.lang.StringBuilder;

public class Program {
    public static void main(String[] args) {

    // Create a new StringBuilder.
    StringBuilder builder = new StringBuilder();

    // Loop and append values.
    for (int i = 0; i < 5; i++) {
        builder.append("abc ");
    }
    // Convert to string.
    String result = builder.toString();

    // Print result.
    System.out.println(result);
    }
}

Those won't necessarily give the same result: find() will get you any descendant node, whereas children() will only get you immediate children that match.

At one point, find() was a lot slower since it had to search for every descendant node that could be a match, and not just immediate children. However, this is no longer true; find() is much quicker due to using native browser methods.

(Solution) Same problem: Windows 10 vs. Oracle 11g (11.2.0.4)

The problem arises again with the final release of Windows 10 (and Server 2016 Preview 3 too) using e. g. Oracle 11g (11.2.0.4, 64 bit) after installation tasks worked fine with several preview builds of Windows 10. All things said above are o. k. resp. do not work.

The ultimate cause is an incompatibility of OracleRemExecService (vs. RemoteExecService.exe): as known, at the beginning of installation process it is created via %TEMP%\oraremservice. If you watch it e. g. with Sysinternals' ProcessMonitor using an appropriate filter, you can see several crashes (the most of them with "buffer Overflow") and restarts, and there are also corresponding with messages in Windows' "System" event log.

If you start (after deleting the HKLM\Software\oracle in the registry) the installation several times (more than three times - see below) it suddenly works. The reason for this behaviour is Windows' "Fault Tolerant Heap" mechanism (see https://msdn.microsoft.com/de-de/library/windows/desktop/dd744764(v=vs.85).aspx) that creates after three attempts within 60 minutes (see http://blogs.technet.com/b/askperf/archive/2009/10/02/windows-7-windows-server-2008-r2-fault-tolerant-heap-and-memory-management.aspx) a FTH entry in HKLM\Software\Microsoft\FTH\State and a corresponding shim in HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers. Although the content of the FTH entry is related to the current process of RemoteExecService.exe you can import the registry keys to a system before you start the DB installation. If you set Windows' %TEMP% environment variable and also %TMP% (due to the fact that Oracle uses both directories while creating the things around OracleRemExecService) to a predefined value (e. g. C:\TEMP) you are able to use this for all your installation tasks as follows (unfortunately, it works only with Windows 10, not Server 2016 - updated 2015-09-24, see below):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers]
"C:\\Temp\\oraremservice\\RemoteExecService.exe"="FaultTolerantHeap"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\FTH\State]
"C:\\Temp\\oraremservice\\RemoteExecService.exe"=hex:10,00,00,00,10,00,00,00,\
  0c,b4,ff,0c,52,00,65,00,6d,00,6f,00,74,00,65,00,45,00,78,00,65,00,63,00,53,\
  00,65,00,72,00,76,00,69,00,63,00,65,00,2e,00,65,00,78,00,65,00,00,00,00,00,\
  00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\
  00,00,00,00,00,00,00,00,00

Update 2015-09-24: With Server 2016 (Preview 3), it's a little bit more tricky: first you also have to set the environment variable %TEMP% e. g. to C:\Temp and to import the registry keys above (after this, it's no bad idea to restart the system). Than you start the Oracle installation using an additional parameter:

setup.exe -debug

If you watch what happens in %TEMP% you can see that the folder %TEMP%\oraremservice\ is created twice: after first creation, the installer seems to notice that the service does not work, deletes the folder and creates it again. After this, the Installation process works as expected.

Update 2015-11-27: - Using Windows Server 2016 Preview 4, the workaround via "setup.exe -debug" is not necessary anymore; you can proceed as described for Windows 10. - Of course, you do not need the procedure with new C:\TEMP vs. %TEMP% and %TMP% if you have a defined user (e. g. Administrator). Then you can use modified registry items like this:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers]
"C:\\Users\\Administrator\\AppData\\Local\\Temp\\oraremservice\\RemoteExecService.exe"="FaultTolerantHeap"

Update 2017-01-31: Tested all builds of Windows 10 (Insider Preview) until now, so we have seen a new problem coming up with build 15002: the Oracle setup isn't able to determine the PATH variable anymore (the variable itself, not a wrong content or so on!). So all attempts to install the Oracle DB fail. Comparing the registry of the Windows versions and "playing around" with this variable and their contents did not help. The only work-around is to edit the related XML file \64bit|32bit\stage\cvu\cvu_prereq.xml and delete in the section all tags ... (or this tag only in the last item "Windows Server 2012"). And btw: despite of we are primary using Oracle 11g this new installation problem also occurs using the up to date setup of Oracle 12c...

Something like this

 string find = "item_manuf_id = 'some value'";
 DataRow[] foundRows = table.Select(find);

You'd have to define alphanumerics exactly, but

/^(\w{3,5})$/ 

Should match any digit/character/_ combination of length 3-5.

If you also need the dash, make sure to escape it (\-) add it, like this: :

/^([\w\-]{3,5})$/ 

Also: the ^ anchor means that the sequence has to start at the beginning of the line (character string), and the $ that it ends at the end of the line (character string). So your value string mustn't contain anything else, or it won't match.

To copy data and schema only (will not copy stored procedures, functions etc.), use the SQL Server Import and Export Wizard, and choose New... when choosing the destination database.

Right Click Database > Tasks > Import Data.

Choose a Data Source

• Data Source: SQL Server Native Client
• Server Name: the remote server
• Authentication:
• Database: the db name

Choose a Destination

• Data Source: SQL Server Native Client
• Server Name: the local server
• Authentication:
• Database: New...

The rest is straight forward.

For fields where NULL is acceptable, you could use var_export($var, true) to output the string, integer, or NULL literal. Note that you would not surround the output with quotes because they will be automatically added or omitted.

For example:

mysql_query("insert into table2 (f1, f2) values ('{$row['string_field']}', ".var_export($row['null_field'], true).")");

This does happened also when you are cloning a repo without selecting any working directory. just make sure you did cd into your working directory and i believe it will work just fine.

Direct to remove the '\n' from the fgets output if every line has '\n'

line[strlen(line) - 1] = '\0';

Otherwise:

void remove_newline_ch(char *line)
{
    int new_line = strlen(line) -1;
    if (line[new_line] == '\n')
        line[new_line] = '\0';
}

You can discover those things easily by yourself:

def hello(*args, **kwargs):
    print kwargs
    print type(kwargs)
    print dir(kwargs)

hello(what="world")

Acoording to RFC 2046 (Multipurpose Internet Mail Extensions):

The recommended action for an implementation that receives an
"application/octet-stream" entity is to simply offer to put the data in a file

So I'd go for that one.

The ChildActionOnly attribute ensures that an action method can be called only as a child method from within a view. An action method doesn’t need to have this attribute to be used as a child action, but we tend to use this attribute to prevent the action methods from being invoked as a result of a user request. Having defined an action method, we need to create what will be rendered when the action is invoked. Child actions are typically associated with partial views, although this is not compulsory.

1. [ChildActionOnly] allowing restricted access via code in View

2. State Information implementation for specific page URL. Example: Payment Page URL (paying only once) razor syntax allows to call specific actions conditional

I vote for a third solution. I use this in my projects and Symfony uses something like this too:

public function __call($val, $x) {
    if(substr($val, 0, 3) == 'get') {
        $varname = strtolower(substr($val, 3));
    }
    else {
        throw new Exception('Bad method.', 500);
    }
    if(property_exists('Yourclass', $varname)) {
        return $this->$varname;
    } else {
        throw new Exception('Property does not exist: '.$varname, 500);
    }
}

This way you have automated getters (you can write setters too), and you only have to write new methods if there is a special case for a member variable.

I solved it by doing like that:

var return_first = (function () {
        var tmp = $.ajax({
            'type': "POST",
            'dataType': 'html',
            'url': "ajax.php?first",
            'data': { 'request': "", 'target': arrange_url, 'method': 
                    method_target },
            'success': function (data) {
                tmp = data;
            }
        }).done(function(data){
                return data;
        });
      return tmp;
    });

• Be careful 'async':fale javascript will be asynchronous.

Link to the PyYAML documentation showing the difference for the default_flow_style parameter. To write it to a file in block mode (often more readable):

d = {'A':'a', 'B':{'C':'c', 'D':'d', 'E':'e'}}
with open('result.yml', 'w') as yaml_file:
    yaml.dump(d, yaml_file, default_flow_style=False)

produces:

A: a
B:
  C: c
  D: d
  E: e

For me it was because I hadn't set an active class on any of the slides.

Queue is an interface; you can't explicitly construct a Queue. You'll have to instantiate one of its implementing classes. Something like:

Queue linkedList = new LinkedList();

Here's a link to the Java tutorial on this subject.

It's not a truly new answer, but - when using img2pdf the page size didn't come out right. So here's what I did to use the image size, I hope it finds someone well:

assuming 1) all images are the same size, 2) placing one image per page, 3) image fills the whole page

from PIL import Image
import img2pdf

with open( 'output.pdf', 'wb' ) as f:
    img = Image.open( '1.jpg' )
    my_layout_fun = img2pdf.get_layout_fun(
        pagesize = ( img2pdf.px_to_pt( img.width, 96 ), img2pdf.px_to_pt( img.height, 96 ) ), # this is where image size is used; 96 is dpi value
        fit = img2pdf.FitMode.into # I didn't have to specify this, but just in case...
    )
    f.write( img2pdf.convert( [ '1.jpg', '2.jpg', '3.jpg' ], layout_fun = my_layout_fun ))

try using math ceil function that makes rounding up. Math Ceil !

It's your "fault" in that that's how Or is defined, so it's the behaviour you should expect:

In a Boolean comparison, the Or operator always evaluates both expressions, which could include making procedure calls. The OrElse Operator (Visual Basic) performs short-circuiting, which means that if expression1 is True, then expression2 is not evaluated.

But you don't have to endure it. You can use OrElse to get short-circuiting behaviour.

So you probably want:

If (example Is Nothing OrElse Not example.Item = compare.Item) Then
    'Proceed
End If

I can't say it reads terribly nicely, but it should work...

You may want to look at potrace.

I think you need to use one of those methods in order to be able to intercept the event before it gets sent to the appropriate components:

Activity.dispatchTouchEvent(MotionEvent) - This allows your Activity to intercept all touch events before they are dispatched to the window.

ViewGroup.onInterceptTouchEvent(MotionEvent) - This allows a ViewGroup to watch events as they are dispatched to child Views.

ViewParent.requestDisallowInterceptTouchEvent(boolean) - Call this upon a parent View to indicate that it should not intercept touch events with onInterceptTouchEvent(MotionEvent).

More information here.

Hope that helps.

Advances in the field + Mozilla's mindset and agenda led to these two projects towards that end:

• Deep Speech
• Common voice

The latter has a 12GB data-set for download. The former allows for training a model with your own audio files to my understanding

Use a keep alive.

On login:

session_start();
$_SESSION['last_action'] = time();

An ajax call every few (eg 20) seconds:

windows.setInterval(keepAliveCall, 20000);

Server side keepalive.php:

session_start();
$_SESSION['last_action'] = time();

On every other action:

session_start();
if ($_SESSION['last_action'] < time() - 30 /* be a little tolerant here */) {
  // destroy the session and quit
}

This works with me :
1- select the cells which shall be be affected by the drop down list .
2- home -> conditional formating -> new rule .
3- format only cells that contain .
4- in format only cells with ... select specific text , in formatting rule "= select Elementary from your drop down list"
if drop list in another sheet then when select Elementary we see "=Sheet3!$F$2" in the new rule , with your own sheet and cell number.
5- format -> fill -> select color -> ok.
6-ok .
do the same for each element in drop down list then you will see the magic !

The spirit of the question, I think, was not truly answered. No, you cannot use a video tag to play rtsp streams as of now. The other answer regarding the link to Chromium guy's "never" is a bit misleading as the linked thread / answer is not directly referring to Chrome playing rtsp via the video tag. Read the entire linked thread, especially the comments at the very bottom and links to other threads.

The real answer is this: No, you cannot just put a video tag on an html 5 page and play rtsp. You need to use a Javascript library of some sort (unless you want to get into playing things with flash and silverlight players) to play streaming video. {IMHO} At the rate the html 5 video discussion and implementation is going, the various vendors of proprietary video standards are not interested in helping this move forward so don't count of the promised ease of use of the video tag unless the browser makers take it upon themselves to somehow solve the problem...again, not likely.{/IMHO}

If you want to have the application code executes using the LOGGED IN USER identity, then enable impersonation. Impersonation can be enabled thru IIS or by adding the following element in the web.config.

<system.web>
<identity impersonate="true"/>

If impersonation is enabled, the application executes using the permissions found in your user account. So if the logged in user has access, to a specific network resource, only then will he be able to access that resource thru the application.

Thank PRAGIM tech for this information from his diligent video

Windows authentication in asp.net Part 87:

https://www.youtube.com/watch?v=zftmaZ3ySMc

But impersonation creates a lot of overhead on the server

The best solution to allow users of certain network groups is to deny anonymous in the web config <authorization><deny users="?"/><authentication mode="Windows"/>

and in your code behind, preferably in the global.asax, use the HttpContext.Current.User.IsInRole :

Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
If HttpContext.Current.User.IsInRole("TheDomain\TheGroup") Then
//code to do when user is in group
End If

NOTE: The Group must be written with a backslash \ i.e. "TheDomain\TheGroup"

I know this is quite old - but searching for an easy solution, I stumbled over this thread... If I got the question right, you were looking for a way to list more than one directory using Get-ChildItem. There seems to be a much easier way using powershell 5.0 - example

Get-ChildItem -Path D:\ -Directory -Name -Exclude tmp,music
   chaos
   docs
   downloads
   games
   pics
   videos

Without the -Exclude clause, tmp and music would still be in that list. If you don't use -Name the -Exclude clause won't work, because of the detailed output of Get-ChildItem. Hope this helps some people that are looking for an easy way to list all directory names without certain ones.

@InjectMocks annotation can be used to inject mock fields into a test object automatically.

In below example @InjectMocks has used to inject the mock dataMap into the dataLibrary .

@Mock
Map<String, String> dataMap ;

@InjectMocks
DataLibrary dataLibrary = new DataLibrary();


    @Test
    public void whenUseInjectMocksAnnotation_() {
        Mockito.when(dataMap .get("aData")).thenReturn("aMeaning");

        assertEquals("aMeaning", dataLibrary .getMeaning("aData"));
    }

You will get rejection message from apple just because the product you have registered for inApp purchase might come under category Non-renewing subscriptions and consumable products. These type of products will not automatically renewable. you need to have explicit restore button in your application.

for other type of products it will automatically restore it.

Please read following text which will clear your concept about this :

Once a transaction has been processed and removed from the queue, your application normally never sees it again. However, if your application supports product types that must be restorable, you must include an interface that allows users to restore these purchases. This interface allows a user to add the product to other devices or, if the original device was wiped, to restore the transaction on the original device.

Store Kit provides built-in functionality to restore transactions for non-consumable products, auto-renewable subscriptions and free subscriptions. To restore transactions, your application calls the payment queue’s restoreCompletedTransactions method. The payment queue sends a request to the App Store to restore the transactions. In return, the App Store generates a new restore transaction for each transaction that was previously completed. The restore transaction object’s originalTransaction property holds a copy of the original transaction. Your application processes a restore transaction by retrieving the original transaction and using it to unlock the purchased content. After Store Kit restores all the previous transactions, it notifies the payment queue observers by calling their paymentQueueRestoreCompletedTransactionsFinished: method.

If the user attempts to purchase a restorable product (instead of using the restore interface you implemented), the application receives a regular transaction for that item, not a restore transaction. However, the user is not charged again for that product. Your application should treat these transactions identically to those of the original transaction. Non-renewing subscriptions and consumable products are not automatically restored by Store Kit. Non-renewing subscriptions must be restorable, however. To restore these products, you must record transactions on your own server when they are purchased and provide your own mechanism to restore those transactions to the user’s devices

To access the tomcat manager from different machine you have to follow bellow steps:

1. Update conf/tomcat-users.xml file with user and some roles:

<role rolename="manager-gui"/>
 <role rolename="manager-script"/>
 <role rolename="manager-jmx"/>
 <role rolename="manager-status"/>
 <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status"/>

Here admin user is assigning roles="manager-gui,manager-script,manager-jmx,manager-status".

Here tomcat user and password is : admin

2. Update webapps/manager/META-INF/context.xml file (Allowing IP address):

Default configuration:

<Context antiResourceLocking="false" privileged="true" >
  
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
  
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>

Here in Valve it is allowing only local machine IP start with 127.\d+.\d+.\d+ .

2.a : Allow specefic IP:

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|YOUR.IP.ADDRESS.HERE" />

Here you just replace |YOUR.IP.ADDRESS.HERE with your IP address

2.b : Allow all IP:

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow=".*" />

Here using allow=".*" you are allowing all IP.

Thanks :)

The only thing that can be a null is a non-primivite.

A boolean which can only hold TRUE or FALSE is a primitive. The TRUE/FALSE in memory are actually numbers (0 and 1)

0 = FALSE

1 = TRUE

So when you instantiate an object it will be null String str; // will equal null

On the other hand if you instaniate a primitive it will be assigned to 0 default.

boolean isTrue; // will be 0

int i; // will be 0

const obj3 = { ...obj1, ...obj2 };_x000D_

console.log(obj3); // {1: 11, 2: 22, 3: 33, 4: 44}

This is an older post, but I do have a better solution. Create a form containing all of your post values as hidden fields and give the form a name such as:

<form name="RefreshForm" method="post" action="http://yoursite/yourscript">

</form>

Then all you need to do in your setTimeout is RefreshForm.submit();

For some reason @Alejandro Gracia answer starts working only after a few second. I found a solution that blocks the RecyclerView instantaneously:

recyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
            @Override
            public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
                return true;
            }
            @Override
            public void onTouchEvent(RecyclerView rv, MotionEvent e) {
            }
            @Override
            public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
            }
        });

Yes, that is correct.

You could use this code:

if (!Object.keys) {
    Object.keys = function (obj) {
        var keys = [],
            k;
        for (k in obj) {
            if (Object.prototype.hasOwnProperty.call(obj, k)) {
                keys.push(k);
            }
        }
        return keys;
    };
}

Then you can use this in older browsers as well:

var len = Object.keys(obj).length;

While you are in it, I suggest to remember some key facts about compareTo() methods

1. CompareTo must be in consistent with equals method e.g. if two objects are equal via equals() , there compareTo() must return zero otherwise if those objects are stored in SortedSet or SortedMap they will not behave properly.

2. CompareTo() must throw NullPointerException if current object get compared to null object as opposed to equals() which return false on such scenario.

To be clearer, I make an example here,

class ClassA {
  class func func1() -> String {
    return "func1"
  }

  static func func2() -> String {
    return "func2"
  }

  /* same as above
  final class func func2() -> String {
    return "func2"
  }
  */
}

static func is same as final class func

Because it is final, we can not override it in subclass as below:

class ClassB : ClassA {
  override class func func1() -> String {
    return "func1 in ClassB"
  }

Indeed there is an API to search google programmatically. The API is called google custom search. For using this API, you will need an Google Developer API key and a cx key. A simple procedure for accessing google search from java program is explained in my blog.

Now dead, here is the Wayback Machine link.

Use:

CREATE PROCEDURE [dbo].[GetByName]
    @TableName NVARCHAR(100)
    AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;
    DECLARE @sSQL nvarchar(500);

    SELECT @sSQL = N'SELECT * FROM' + QUOTENAME(@TableName);

    EXEC sp_executesql @sSQL
END

`Display

$('#cbxShowHide').click(function(){ this.checked?$('#block').show(1000):$('#block').hide(1000); //time for show });`

ALTER TABLE t_name modify c_name INT(10) AUTO_INCREMENT PRIMARY KEY;

Also make sure that the name of the variable is not some kind of a language keyword. For instance, the following produces the same type of error:

var history = [];
history.push("what a mess");

replacing it for:

var history123 = [];
history123.push("pray for a better language");

works as expected.

I think the point of those different types of logging is if you want your app to basically self filter its own logs. So Verbose could be to log absolutely everything of importance in your app, then the debug level would log a subset of the verbose logs, and then Info level will log a subset of the debug logs. When you get down to the Error logs, then you just want to log any sort of errors that may have occured. There is also a debug level called Fatal for when something really hits the fan in your app.

In general, you're right, it's basically arbitrary, and it's up to you to define what is considered a debug log versus informational, versus and error, etc. etc.

The full command is:

dir /b /a-d

Let me break it up;

Basically the /b is what you look for.

/a-d will exclude the directory names.

For more information see dir /? for other arguments that you can use with the dir command.

Just to improve Wael's answer and put it on a single line:

dt.Columns.Add("Better", typeof(Boolean)).SetOrdinal(0);

UPDATE: Note that this works when you don't need to do anything else with the DataColumn. Add() returns the column in question, SetOrdinal() returns nothing.
