If all you want to do is rotate the image endlessly, this works quite well, and is very simple:

NSTimeInterval duration = 10.0f;
CGFloat angle = M_PI / 2.0f;
CGAffineTransform rotateTransform = CGAffineTransformRotate(imageView.transform, angle);

[UIView animateWithDuration:duration delay:0 options:UIViewAnimationOptionRepeat| UIViewAnimationOptionCurveLinear animations:^{
    imageView.transform = rotateTransform;
} completion:nil];

In my experience, this works flawlessly, but be sure your image is capable of being rotated around its center without any offsets, or the image animation will "jump" once it makes it around to PI.

To change the direction of the spin, change the sign of angle (angle *= -1).

Update Comments by @AlexPretzlav made me revisit this, and I realized that when I wrote this the image I was rotating was mirrored along both the vertical and horizontal axis, meaning the image was indeed only rotating 90 degrees and then resetting, though it looked like it was continuing to rotate all the way around.

So, if your image is like mine was, this will work great, however, if the image is not symmetrical, you'll notice the "snap" back to the original orientation after 90 degrees.

To rotate a non-symmetrical image, you're better off with the accepted answer.

One of these less elegant solutions, seen below, will truly rotate the image, but there may be a noticeable stutter when the animation is restarted:

- (void)spin
{
    NSTimeInterval duration = 0.5f;
    CGFloat angle = M_PI_2;
    CGAffineTransform rotateTransform = CGAffineTransformRotate(self.imageView.transform, angle);

    [UIView animateWithDuration:duration delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
        self.imageView.transform = rotateTransform;
    } completion:^(BOOL finished) {
        [self spin];
    }];
}

You could also do this just with blocks, as @richard-j-ross-iii suggests, but you will get a retain loop warning since the block is capturing itself:

__block void(^spin)() = ^{
    NSTimeInterval duration = 0.5f;
    CGFloat angle = M_PI_2;
    CGAffineTransform rotateTransform = CGAffineTransformRotate(self.imageView.transform, angle);

    [UIView animateWithDuration:duration delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
        self.imageView.transform = rotateTransform;
    } completion:^(BOOL finished) {
        spin();
    }];
};
spin();

I like the simple elegance of Peter Sarnowski's answer, but it can cause problems when you can't rely on EXIF metadata and the like. In situations where you need to rotate the actual image data I would recommend something like this:

- (UIImage *)rotateImage:(UIImage *) img
{
    CGSize imgSize = [img size];
    UIGraphicsBeginImageContext(imgSize);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextRotateCTM(context, M_PI_2);
    CGContextTranslateCTM(context, 0, -640);
    [img drawInRect:CGRectMake(0, 0, imgSize.height, imgSize.width)];
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return newImage;
}

The above code takes an image whose orientation is Landscape (can't remember if it's Landscape Left or Landscape Right) and rotates it into Portrait. It is an example which can be modified for your needs.

The key arguments you would have to play with are CGContextRotateCTM(context, M_PI_2) where you decide how much you want to rotate by, but then you have to make sure the picture still draws on the screen using CGContextTranslateCTM(context, 0, -640). This last part is quite important to make sure you see the image and not a blank screen.

aspirinemaga, just replace:

$this->db->set('time', 'NOW()', FALSE);
$this->db->insert('mytable', $data);

for it:

$this->db->set('time', 'NOW() + INTERVAL 1 DAY', FALSE);
$this->db->insert('mytable', $data);

Yeah, for most cases, you don't need to create a class with getters and setters. Just create a new Dictionary and bind it to the data source. Here's an example in VB using a for loop to set the DisplayMember and ValueMember of a combo box from a list:

        Dim comboSource As New Dictionary(Of String, String)()
        cboMenu.Items.Clear()
        For I = 0 To SomeList.GetUpperBound(0)
            comboSource.Add(SomeList(I).Prop1, SomeList(I).Prop2)
        Next I
        cboMenu.DataSource = New BindingSource(comboSource, Nothing)
        cboMenu.DisplayMember = "Value"
        cboMenu.ValueMember = "Key"

Then you can set up a data grid view's rows according to the value or whatever you need by calling a method on click:

Private Sub cboMenu_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cboMenu.SelectionChangeCommitted
    SetListGrid(cboManufMenu.SelectedValue)
End Sub

Dayle Reese has an amazing set of color schemes available for use in both AndroidStudio and Intellij. Depending on the IDE you are using, these ICLS files go into a particular directory (This is for Windows):

Android Studio

%USERPROFILE%/.AndroidStudio/config/colors

IntelliJ

%USERPROFILE%/.IntelliJIdea/config/colors

Once you've placed the ICLS files in one of the directories above, relaunch the IDE so that it picks up the new themes. There is also a nice page containing a preview of most/all the themes so you can figure out which ones you like most. Enjoy.

print [s for s in list if sub in s]

If you want them separated by newlines:

print "\n".join(s for s in list if sub in s)

Full example, with case insensitivity:

mylist = ['abc123', 'def456', 'ghi789', 'ABC987', 'aBc654']
sub = 'abc'

print "\n".join(s for s in mylist if sub.lower() in s.lower())

In my case, this has been resolved by going to control panel > java > security > then add url in the exception site list. Then apply. Test again the site and it should now allow you to run the local java.

You put select query before update queries, so you just see initial data. Put select * from stuff; to the end of list.

I couldn't find any exact and valid way to do this. So after a whole day, I came with this mixed code achieved from different sources and trying to get the job done.

But it is still generating an exception ExecuteNonQuery: CommandText property has not been Initialized even though it successfully runs the script file - in my case, it successfully creates the database and inserts data on the first startup.

            cn.Open();
            cm.ExecuteNonQuery();
            cn.Close();
        }
        catch
        {

        }
        try
        {
            //Application.StartupPath is the location where the application is Installed
            //Here File Path Can Be Provided Via OpenFileDialog
            if (File.Exists(Application.StartupPath + "\\script.sql"))
            {
                string script = null;
                script = File.ReadAllText(Application.StartupPath + "\\script.sql");
                string[] ScriptSplitter = script.Split(new string[] { "GO" }, StringSplitOptions.None);
                using (cn = new SqlConnection(@"Data Source=.\SQLEXPRESS;Initial Catalog=master;Integrated Security=True"))
                {
                    cn.Open();
                    foreach (string str in ScriptSplitter)
                    {
                        using (cm = cn.CreateCommand())
                        {
                            cm.CommandText = str;
                            cm.ExecuteNonQuery();
                        }
                    }
                }
            }
        }
        catch
        {

        }

    }

}

I would suggest that the current solution is to use my package urllib2_prior_auth which solves this pretty nicely (I work on inclusion to the standard lib.

.getBoundingClientRect() returns the size of an element and its position relative to the viewport.We can easily get following

• left, right
• top, bottom
• height, width

Example :

var element = d3.select('.elementClassName').node();
element.getBoundingClientRect().width;

Steps to start Apache Tomcat using cmd:
1. Firstly check that the JRE_HOME or JAVA_HOME is a variable available in environment variables.(If it is not create a new variable JRE_HOME or JAVA_HOME)
2. Goto cmd and change your working directory to bin path where apache is installed (or extracted).
3. Type Command -> catalina.bat start to start the server.
4. Type Command -> catalina.bat stop to stop the server.

You can use yourstring.split("\x09"); I tested it, and it works.

This happened to me when I tried to use my older code in new android with androidx implementations. change your XML definition to;

<androidx.appcompat.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@color/colorPrimary"
            android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
            app:titleTextColor="@android:color/white" />

then in your java code;

import androidx.appcompat.widget.Toolbar;

Use the Desktop#browse(URI) method. It opens a URI in the user's default browser.

public static boolean openWebpage(URI uri) {
    Desktop desktop = Desktop.isDesktopSupported() ? Desktop.getDesktop() : null;
    if (desktop != null && desktop.isSupported(Desktop.Action.BROWSE)) {
        try {
            desktop.browse(uri);
            return true;
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    return false;
}

public static boolean openWebpage(URL url) {
    try {
        return openWebpage(url.toURI());
    } catch (URISyntaxException e) {
        e.printStackTrace();
    }
    return false;
}

If you need a Swift Implementation of this follow the directions on the accepted answer and then in you UITableViewController implement the following methods:

override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    return tableView.dequeueReusableCell(withIdentifier: "CustomHeader")
}

override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 75
}

Try this:

[^a-zA-Z0-9 :]

JavaScript example:

"!@#$%* ABC def:123".replace(/[^a-zA-Z0-9 :]/g, ".")

See a online example:

http://jsfiddle.net/vhMy8/

I found this way to be a good one, without having to worry too much about charsets and arrays, or iconv:

function replace_accents($str) {
   $str = htmlentities($str, ENT_COMPAT, "UTF-8");
   $str = preg_replace('/&([a-zA-Z])(uml|acute|grave|circ|tilde|ring);/','$1',$str);
   return html_entity_decode($str);
}

You need to put your main code on the OnStart method.

This other SO answer of mine might help.

You will need to put some code to enable debugging within visual-studio while maintaining your application valid as a windows-service. This other SO thread cover the issue of debugging a windows-service.

EDIT:

Please see also the documentation available here for the OnStart method at the MSDN where one can read this:

Do not use the constructor to perform processing that should be in OnStart. Use OnStart to handle all initialization of your service. The constructor is called when the application's executable runs, not when the service runs. The executable runs before OnStart. When you continue, for example, the constructor is not called again because the SCM already holds the object in memory. If OnStop releases resources allocated in the constructor rather than in OnStart, the needed resources would not be created again the second time the service is called.

Iterating through the registry key "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" seems to give a comprehensive list of installed applications.

Aside from the example below, you can find a similar version to what I've done here.

This is a rough example, you'll probaby want to do something to strip out blank rows like in the 2nd link provided.

string registry_key = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
using(Microsoft.Win32.RegistryKey key = Registry.LocalMachine.OpenSubKey(registry_key))
{
    foreach(string subkey_name in key.GetSubKeyNames())
    {
        using(RegistryKey subkey = key.OpenSubKey(subkey_name))
        {
            Console.WriteLine(subkey.GetValue("DisplayName"));
        }
    }
}

Alternatively, you can use WMI as has been mentioned:

ManagementObjectSearcher mos = new ManagementObjectSearcher("SELECT * FROM Win32_Product");
foreach(ManagementObject mo in mos.Get())
{
    Console.WriteLine(mo["Name"]);
}

But this is rather slower to execute, and I've heard it may only list programs installed under "ALLUSERS", though that may be incorrect. It also ignores the Windows components & updates, which may be handy for you.

With Swift 5 and iOS 12.2, you should try the following code in order to solve your problem:

CustomCell.swift

import UIKit

class CustomCell: UITableViewCell {

    // Link those IBOutlets with the UILabels in your .XIB file
    @IBOutlet weak var middleLabel: UILabel!
    @IBOutlet weak var leftLabel: UILabel!
    @IBOutlet weak var rightLabel: UILabel!

}

TableViewController.swift

import UIKit

class TableViewController: UITableViewController {

    let items = ["Item 1", "Item2", "Item3", "Item4"]

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.register(UINib(nibName: "CustomCell", bundle: nil), forCellReuseIdentifier: "CustomCell")
    }

    // MARK: - UITableViewDataSource

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return items.count
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomCell

        cell.middleLabel.text = items[indexPath.row]
        cell.leftLabel.text = items[indexPath.row]
        cell.rightLabel.text = items[indexPath.row]

        return cell
    }

}

The image below shows a set of constraints that work with the provided code without any constraints ambiguity message from Xcode:

There's still no simple answer. It depends on your scenario. MSDN has documentation to help you decide.

There are other options covered here. Instead of storing in the file system directly or in a BLOB, you can use the FileStream or File Table in SQL Server 2012. The advantages to File Table seem like a no-brainier (but admittedly I have no personal first-hand experience with them.)

The article is definitely worth a read.

If Table variable has large data, then instead of table variable(@table) create temp table (#table).table variable doesn't allow to create index after insert.

 CREATE TABLE #Table(C1 int,       
  C2 NVarchar(100) , C3 varchar(100)
  UNIQUE CLUSTERED (c1) 
 ); 

1. Create table with unique clustered index

2. Insert data into Temp "#Table" table

3. Create non clustered indexes.

    CREATE NONCLUSTERED INDEX IX1  ON #Table (C2,C3);
   

Look at your commit graph (with gitk or a similar program). You will see commits from the pull request, and you will see your own commits, and a merge commit (if it was not a fast-forward merge). You just have to find the last of your own commits before the merge, and reset the branch to this commit.

(If you have the branch's reflog, it should be even easier to find the commit before the merge.)

(Edit after more information in comments:)

Okay, lets look at the graph:

I assume the last (rightmost) commit was your wrong merge by pull request, which merged the blue line seen here. Your last good commit would be the one before on the black line, here marked in red:

Reset to this commit, and you should be fine.

This means, in your local working copy do this (after making sure you have no more uncommitted stuff, for example by git stash):

git checkout master
git reset --hard 7a62674ba3df0853c63539175197a16122a739ef
gitk 

Now confirm that you are really on the commit I marked there, and you will see none of the pulled stuff in its ancestry.

git push -f origin master

(if your github remote is named origin - else change the name).

Now everything should look right on github, too. The commits will still be in your repository, but not reachable by any branch, thus should not do any harm there. (And they will be still on RogerPaladin's repository, of course.)

(There might be a Github specific web-only way of doing the same thing, but I'm not too familiar with Github and its pull request managing system.)

Note that if anyone else already might have pulled your master with the wrong commit, they then have the same problem as you currently have, and can't really contribute back. before resetting to your new master version.

If it is likely that this happened, or you simply want to avoid any problems, use the git revert command instead of git reset, to revert the changes with a new commit, instead of setting back to an older one. (Some people think you should never do reset with published branches.) See other answers to this question on how to do this.

For the future:

If you want only some of the commits of RogerPaladin's branch, consider using cherry-pick instead of merge. Or communicate to RogerPaladin to move them to a separate branch and send a new pull request.

In the your first journey in spring boot project I recommend you to start with Spring Starter Try this link here.

It will auto generate the project structure for you like this.application.perperties it will be under /resources.

application.properties important change,

server.port = Your PORT(XXXX) by default=8080
server.servlet.context-path=/api (SpringBoot version 2.x.)
server.contextPath-path=/api (SpringBoot version < 2.x.)

Any way you can use application.yml in case you don't want to make redundancy properties setting.

Example
application.yml

server:
   port: 8080 
   contextPath: /api

application.properties

server.port = 8080
server.contextPath = /api

Symfony is smart and knows how to make the find() by itself :

public function deleteGuestAction(Guest $guest)
{
    if (!$guest) {
        throw $this->createNotFoundException('No guest found');
    }

    $em = $this->getDoctrine()->getEntityManager();
    $em->remove($guest);
    $em->flush();

    return $this->redirect($this->generateUrl('GuestBundle:Page:viewGuests.html.twig'));
}

To send the id in your controller, use {{ path('your_route', {'id': guest.id}) }}

The ability to search commits has recently been added to GitHub.

To search for a hash, just enter at least the first 7 characters in the search box. Then on the results page, click the "Commits" tab to see matching commits (but only on the default branch, usually master), or the "Issues" tab to see pull requests containing the commit.

To be more explicit you can add the hash: prefix to the search, but it's not really necessary.

There is also a REST API (at the time of writing it is still in preview).

This code will count frequency and remove duplicate elements:

from collections import Counter

str1='the cat sat on the hat hat'

int_list=str1.split();

unique_list = []
for el in int_list:

    if el not in unique_list:
        unique_list.append(el)
    else:
        print "Element already in the list"

print unique_list

c=Counter(int_list)

c.values()

c.keys()

print c

Not Found Exceptions

Sometimes you may wish to throw an exception if a model is not found. This is particularly useful in routes or controllers. The findOrFail and firstOrFail methods will retrieve the first result of the query. However, if no result is found, a Illuminate\Database\Eloquent\ModelNotFoundException will be thrown:

$model = App\Flight::findOrFail(1);

$model = App\Flight::where('legs', '>', 100)->firstOrFail();

If the exception is not caught, a 404 HTTP response is automatically sent back to the user. It is not necessary to write explicit checks to return 404 responses when using these methods:

Route::get('/api/flights/{id}', function ($id) {
    return App\Flight::findOrFail($id);
});

It looks like that many people use API keys as a security solution. The bottom line is: Never treat API keys as secret it is not. On https or not, whoever can read the request can see the API key and can make whatever call they want. An API Key should be just as a 'user' identifier as its not a complete security solution even when used with ssl.

The better description is in Eugene Osovetsky link to: When working with most APIs, why do they require two types of authentication, namely a key and a secret? Or check http://nordicapis.com/why-api-keys-are-not-enough/

wt = tt - cpu tm.
Tt = cpu tm + wt.

Where wt is a waiting time and tt is turnaround time. Cpu time is also called burst time.

You can find the pg_config directory using its namesake:

$ pg_config --bindir
/usr/lib/postgresql/9.1/bin
$ 

Tested on Mac and Debian. The only wrinkle is that I can't see how to find the bindir for different versions of postgres installed on the same machine. It's fairly easy to guess though! :-)

Note: I updated my pg_config to 9.5 on Debian with:

sudo apt-get install postgresql-server-dev-9.5

I also faced the similar issues, changing the version from 2.0.0.RELEASE to 1.5.10.RELEASE worked for me, please try it before downgrading the maven version

The only way that I was able to get the column names was using the following query:

select COLUMN_NAME

WHERE table_name like 'USERS'

As others have mentioned: CSS-3 says that you can use the rgba(...) syntax to specify a border color with an opacity (alpha) value.

here's a quick example if you'd like to check it.

• It works in Safari and Chrome (probably works in all webkit browsers).

• It works in Firefox

• I doubt that it works at all in IE, but I suspect that there is some filter or behavior that will make it work.

There's also this stackoverflow post, which suggests some other issues--namely, that the border renders on-top-of any background color (or background image) that you've specified; thus limiting the usefulness of border alpha in many cases.

Regarding Bruce Adams answer:

Your answer creates dangerous confusion. DESTDIR is intended for installs out of the root tree. It allows one to see what would be installed in the root tree if one did not specify DESTDIR. PREFIX is the base directory upon which the real installation is based.

For example, PREFIX=/usr/local indicates that the final destination of a package is /usr/local. Using DESTDIR=$HOME will install the files as if $HOME was the root (/). If, say DESTDIR, was /tmp/destdir, one could see what 'make install' would affect. In that spirit, DESTDIR should never affect the built objects.

A makefile segment to explain it:

install:
    cp program $DESTDIR$PREFIX/bin/program

Programs must assume that PREFIX is the base directory of the final (i.e. production) directory. The possibility of symlinking a program installed in DESTDIR=/something only means that the program does not access files based upon PREFIX as it would simply not work. cat(1) is a program that (in its simplest form) can run from anywhere. Here is an example that won't:

prog.pseudo.in:
    open("@prefix@/share/prog.db")
    ...

prog:
    sed -e "s/@prefix@/$PREFIX/" prog.pseudo.in > prog.pseudo
    compile prog.pseudo

install:
    cp prog $DESTDIR$PREFIX/bin/prog
    cp prog.db $DESTDIR$PREFIX/share/prog.db

If you tried to run prog from elsewhere than $PREFIX/bin/prog, prog.db would never be found as it is not in its expected location.

Finally, /etc/alternatives really does not work this way. There are symlinks to programs installed in the root tree (e.g. vi -> /usr/bin/nvi, vi -> /usr/bin/vim, etc.).

You need it to install development iPhone applications on development devices.

Here's how to create one, and the reference for this answer:

Format as JSON (you can "beautify" in IDE later):

local function format_any_value(obj, buffer)
    local _type = type(obj)
    if _type == "table" then
        buffer[#buffer + 1] = '{"'
        for key, value in next, obj, nil do
            buffer[#buffer + 1] = tostring(key) .. '":'
            format_any_value(value, buffer)
            buffer[#buffer + 1] = ',"'
        end
        buffer[#buffer] = '}' -- note the overwrite
    elseif _type == "string" then
        buffer[#buffer + 1] = '"' .. obj .. '"'
    elseif _type == "boolean" or _type == "number" then
        buffer[#buffer + 1] = tostring(obj)
    else
        buffer[#buffer + 1] = '"???' .. _type .. '???"'
    end
end

Usage:

local function format_as_json(obj)
    if obj == nil then return "null" else
        local buffer = {}
        format_any_value(obj, buffer)
        return table.concat(buffer)
    end
end

local function print_as_json(obj)
    print(_format_as_json(obj))
end

print_as_json {1, 2, 3}
print_as_json(nil)
print_as_json("string")
print_as_json {[1] = 1, [2] = 2, three = { { true } }, four = "four"}

BTW, I also wrote several other solutions: a very fast one, and one with special characters escaping: https://github.com/vn971/fast_json_encode

You need to run your code AFTER jQuery finished loading

var script = document.createElement('script'); 
document.head.appendChild(script);    
script.type = 'text/javascript';
script.src = "//ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js";
script.onload = function(){
    // your jQuery code here
} 

or if you're running it in an async function you could use await in the above code

var script = document.createElement('script'); 
document.head.appendChild(script);    
script.type = 'text/javascript';
script.src = "//ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js";
await script.onload
// your jQuery code here

If you want to check first if jQuery already exists in the page, try this

If you are using Java 8 and don't want to manipulate CompletableFutures, I have written a tool to retrieve results for a List<Future<T>> using streaming. The key is that you are forbidden to map(Future::get) as it throws.

public final class Futures
{

    private Futures()
    {}

    public static <E> Collector<Future<E>, Collection<E>, List<E>> present()
    {
        return new FutureCollector<>();
    }

    private static class FutureCollector<T> implements Collector<Future<T>, Collection<T>, List<T>>
    {
        private final List<Throwable> exceptions = new LinkedList<>();

        @Override
        public Supplier<Collection<T>> supplier()
        {
            return LinkedList::new;
        }

        @Override
        public BiConsumer<Collection<T>, Future<T>> accumulator()
        {
            return (r, f) -> {
                try
                {
                    r.add(f.get());
                }
                catch (InterruptedException e)
                {}
                catch (ExecutionException e)
                {
                    exceptions.add(e.getCause());
                }
            };
        }

        @Override
        public BinaryOperator<Collection<T>> combiner()
        {
            return (l1, l2) -> {
                l1.addAll(l2);
                return l1;
            };
        }

        @Override
        public Function<Collection<T>, List<T>> finisher()
        {
            return l -> {

                List<T> ret = new ArrayList<>(l);
                if (!exceptions.isEmpty())
                    throw new AggregateException(exceptions, ret);

                return ret;
            };

        }

        @Override
        public Set<java.util.stream.Collector.Characteristics> characteristics()
        {
            return java.util.Collections.emptySet();
        }
    }

This needs an AggregateException that works like C#'s

public class AggregateException extends RuntimeException
{
    /**
     *
     */
    private static final long serialVersionUID = -4477649337710077094L;

    private final List<Throwable> causes;
    private List<?> successfulElements;

    public AggregateException(List<Throwable> causes, List<?> l)
    {
        this.causes = causes;
        successfulElements = l;
    }

    public AggregateException(List<Throwable> causes)
    {
        this.causes = causes;
    }

    @Override
    public synchronized Throwable getCause()
    {
        return this;
    }

    public List<Throwable> getCauses()
    {
        return causes;
    }

    public List<?> getSuccessfulElements()
    {
        return successfulElements;
    }

    public void setSuccessfulElements(List<?> successfulElements)
    {
        this.successfulElements = successfulElements;
    }

}

This component acts exactly as C#'s Task.WaitAll. I am working on a variant that does the same as CompletableFuture.allOf (equivalento to Task.WhenAll)

The reason why I did this is that I am using Spring's ListenableFuture and don't want to port to CompletableFuture despite it is a more standard way

The variable '$$' contains the PID.

In order to resolve this, Kindly go to the below path

Project-->Properties-->Application-->TargetFramework

and change the Framework to ".NET Framework 4".

Once you do this, the project will close and re-open.

This should solve the error

(but for some reason @Karan Modi's answer does not...)

next right-click the references tab in the solution explorer and choose add reference,

choose "System.Web"

(declaring the namespace directly by "using System.Web;" doesnt seems to be enough...you have to add it to the solution explorer...i cant understand why - which is no surprise because i am a cobol programmer..

This below code will give selected row, you can parse the values from it and send to the AJAX call.

$(".selected").click(function () {
var row = $(this).parent().parent().parent().html();            
});

You can replace

<input type="text" id="userid" name="userid" value="Please enter the user ID" />

With:

<input type="text" id="userid" name="userid" placeholder="Please enter the user ID" />

The placeholder is used to replace value as how you wanted people to be able to Type in the text box without having to click multiple times or using ctrl + a. Placeholder makes it so it isn't a value but as the name suggests a place holder. That is what is used in multiple online forms that says "Username here" or "Email" and when you click on it the "Email" disappears and you can start typing right away.

Sun's JDK6:

I believe that it grows to 15 elements. Not coding it out, but looking at the grow() code in the jdk.

int newCapacity then = 10 + (10 >> 1) = 15.

/**
 * Increases the capacity to ensure that it can hold at least the
 * number of elements specified by the minimum capacity argument.
 *
 * @param minCapacity the desired minimum capacity
 */
private void grow(int minCapacity) {
    // overflow-conscious code
    int oldCapacity = elementData.length;
    int newCapacity = oldCapacity + (oldCapacity >> 1);
    if (newCapacity - minCapacity < 0)
        newCapacity = minCapacity;
    if (newCapacity - MAX_ARRAY_SIZE > 0)
        newCapacity = hugeCapacity(minCapacity);
    // minCapacity is usually close to size, so this is a win:
    elementData = Arrays.copyOf(elementData, newCapacity);
}

From the Javadoc, it says this is from Java 2 and on, so its a safe bet in the Sun JDK.

EDIT : for those who didn't get what's the connection between multiplying factor 1.5 and int newCapacity = oldCapacity + (oldCapacity >> 1);

>> is right shift operator which reduces a number to its half. Thus,
int newCapacity = oldCapacity + (oldCapacity >> 1);
=> int newCapacity = oldCapacity + 0.5*oldCapacity;
=> int newCapacity = 1.5*oldCapacity ;

Given this example url:

http://www.example.com/some-dir/yourpage.php?q=bogus&n=10

$_SERVER['REQUEST_URI'] will give you:

/some-dir/yourpage.php?q=bogus&n=10

Whereas $_GET['q'] will give you:

bogus

In other words, $_SERVER['REQUEST_URI'] will hold the full request path including the querystring. And $_GET['q'] will give you the value of parameter q in the querystring.

The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.

See also here: How to supply value to an annotation from a Constant java

It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.

Better than all above is ever to use Standard C specification for struct initialization:

struct StructType structVar = {0};

Here are all bits zero (ever).

There is no difference between these two declarations, and both have the same performance.

I performed the below steps and it worked for me:

1) connect to SQL Server->Security->logins->search for the particular user->Properties->server Roles-> enable "sys admin" check box

This can be achieved by doing

(a2 & a1) == a2

This creates the intersection of both arrays, returning all elements from a2 which are also in a1. If the result is the same as a2, you can be sure you have all elements included in a1.

This approach only works if all elements in a2 are different from each other in the first place. If there are doubles, this approach fails. The one from Tempos still works then, so I wholeheartedly recommend his approach (also it's probably faster).

That is not how the PUBLIC_URL variable is used. According to the documentation, you can use the PUBLIC_URL in your HTML:

<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">

Or in your JavaScript:

render() {
  // Note: this is an escape hatch and should be used sparingly!
  // Normally we recommend using `import` for getting asset URLs
  // as described in “Adding Images and Fonts” above this section.
  return <img src={process.env.PUBLIC_URL + '/img/logo.png'} />;
}

The PUBLIC_URL is not something you set to a value of your choosing, it is a way to store files in your deployment outside of Webpack's build system.

To view this, run your CRA app and add this to the src/index.js file:

console.log('public url: ', process.env.PUBLIC_URL)

You'll see the URL already exists.

Read more in the CRA docs.

Every package should be responsible for autoloading itself, what are you trying to achieve with autoloading classes that are out of the package you define?

One workaround if it's for your application itself is to add a namespace to the loader instance, something like this:

<?php

$loader = require 'vendor/autoload.php';
$loader->add('AppName', __DIR__.'/../src/');

For anyone who looks at this today after 2 years, Visual Studio 2019 (Community edition as well) shows the references

Most of the roles you see were defined as part of ARIA 1.0, and then later incorporated into HTML via supporting specs like HTML-AAM. Some of the new HTML5 elements (dialog, main, etc.) are even based on the original ARIA roles.

http://www.w3.org/TR/wai-aria/

There are a few primary reasons to use roles in addition to your native semantic element.

Reason #1. Overriding the role where no host language element is appropriate or, for various reasons, a less semantically appropriate element was used.

In this example, a link was used, even though the resulting functionality is more button-like than a navigation link.

<a href="#" role="button" aria-label="Delete item 1">Delete</a>
<!-- Note: href="#" is just a shorthand here, not a recommended technique. Use progressive enhancement when possible. -->

Screen readers users will hear this as a button (as opposed to a link), and you can use a CSS attribute selector to avoid class-itis and div-itis.

[role="button"] {
  /* style these as buttons w/o relying on a .button class */
}

[Update 7 years later: removed the * selector to make some commenters happy, since the old browser quirk that required universal selector on attribute selectors is unnecessary in 2020.]

Reason #2. Backing up a native element's role, to support browsers that implemented the ARIA role but haven't yet implemented the native element's role.

For example, the "main" role has been supported in browsers for many years, but it's a relatively recent addition to HTML5, so many browsers don't yet support the semantic for <main>.

<main role="main">…</main>

This is technically redundant, but helps some users and doesn't harm any. In a few years, this technique will likely become unnecessary for main.

Reason #3. Update 7 years later (2020): As at least one commenter pointed out, this is now very useful for custom elements, and some spec work is underway to define the default accessibility role of a web component. Even if/once that API is standardized, there may be need to override the default role of a component.

Note/Reply

You also wrote:

I see some people make up their own. Is that allowed or a correct use of the role attribute?

That's an allowed use of the attribute unless a real role is not included. Browsers will apply the first recognized role in the token list.

<span role="foo link note bar">...</a>

Out of the list, only link and note are valid roles, and so the link role will be applied in the platform accessibility API because it comes first. If you use custom roles, make sure they don't conflict with any defined role in ARIA or the host language you're using (HTML, SVG, MathML, etc.)

One important thing to mention is that after updating your Xcode to 7 beta you might be getting the following message: "Method does not override any method from its superclass". That's because of the arguments' optionality. Make sure that your observation handler looks exactly as follows:

override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [NSObject : AnyObject]?, context: UnsafeMutablePointer<Void>)

Actually, this is an ongoing problem. While Andy is right about the downloaded source, .val(...) and .attr('value',...) don't seem to actually modify the html. I think this is a javascript problem and not a jquery problem. If you had used firebug even you would have had the same question. While it seems that if you submit the form with the modified values it will go through, the html does not change. I ran into this issue trying to create a print preview of the modified form (doing [form].html()) it copies everything okay, including all changes except values changes. Thus, my modal print preview is somewhat useless... my workaround may have to be to 'build' a hidden form containing the values they have added, or generate the preview independently and make each modification the user makes also modify the preview. Both are inoptimal, but unless someone figures out why the value-setting behavior does not change the html (in the DOM i'm assuming) it will have to do.

Update your build.gradle(Module:app) add compileOptions block and add JavaVersion.VERSION_1_8

apply plugin: 'com.android.application'

android {
    .................
    .........................
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

As a general statement, its good to make your if conditionals as readable as possible. For your example, using ! is ok. the problem is when things look like

if ((a.b && c.d.e) || !f)

you might want to do something like

bool isOk = a.b;
bool isStillOk = c.d.e
bool alternateOk = !f

then your if statement is simplified to

if ( (isOk && isStillOk) || alternateOk)

It just makes the code more readable. And if you have to debug, you can debug the isOk set of vars instead of having to dig through the variables in scope. It is also helpful for dealing with NPEs -- breaking code out into simpler chunks is always good.

Update: Per konrad.kruczynski's answer, the following is true for versions of .NET up to and including 4.0.

You can use the MethodImplAttribute class to prevent a method from being inlined...

[MethodImpl(MethodImplOptions.NoInlining)]
void SomeMethod()
{
    // ...
}

...but there is no way to do the opposite and force it to be inlined.

This seems pretty clean, to me.

def magic( aList, base=10 ):
    n= 0
    for d in aList:
        n = base*n + d
    return n

You can change the app icon under project properties. Individual form icons under form properties.

Here's another dodge that I came up with for my base repository class where I needed to order by an arbitrary number of columns:

public function findAll(array $where = [], array $with = [], array $orderBy = [], int $limit = 10)
{
    $result = $this->model->with($with);
    $dataSet = $result->where($where)
        // Conditionally use $orderBy if not empty
        ->when(!empty($orderBy), function ($query) use ($orderBy) {
            // Break $orderBy into pairs
            $pairs = array_chunk($orderBy, 2);
            // Iterate over the pairs
            foreach ($pairs as $pair) {
                // Use the 'splat' to turn the pair into two arguments
                $query->orderBy(...$pair);
            }
        })
        ->paginate($limit)
        ->appends(Input::except('page'));

    return $dataSet;
}

Now, you can make your call like this:

$allUsers = $userRepository->findAll([], [], ['name', 'DESC', 'email', 'ASC'], 100);

you can't. foo-bar is not an identifier. rename the file to foo_bar.py

Edit: If import is not your goal (as in: you don't care what happens with sys.modules, you don't need it to import itself), just getting all of the file's globals into your own scope, you can use execfile

# contents of foo-bar.py
baz = 'quux'

>>> execfile('foo-bar.py')
>>> baz
'quux'
>>> 

Make sure to check if the event related to the button click is not propagating to child elements as an icon tag (<i class="fa...) inside the button for example, so this propagation can make you miss the button $(this).attr('data-X10') and hit the icon tag.

<button data-x10="C5">
    <i class="fa fa-check"></i> Text
</button>

$('button.toggleStatus').on('click', function (event) {
    event.preventDefault();
    event.stopPropagation();
    $(event.currentTarget).attr('data-X10');
});

Sharer.php no longer allows you to customize. The page you share will be scraped for OG Tags and that data will be shared.

To properly customize, use FB.UI which comes with the JS-SDK.

It's just PHP, not HTML.

It parses all HTML fields with [] into an array.

So you can have

<input type="checkbox" name="food[]" value="apple" />
<input type="checkbox" name="food[]" value="pear" />

and when submitted, PHP will make $_POST['food'] an array, and you can access its elements like so:

echo $_POST['food'][0]; // would output first checkbox selected

or to see all values selected:

foreach( $_POST['food'] as $value ) {
    print $value;
}

Anyhow, don't think there is a specific name for it

Check if the cross product of b-a and c-a is0: that means all the points are collinear. If they are, check if c's coordinates are between a's and b's. Use either the x or the y coordinates, as long as a and b are separate on that axis (or they're the same on both).

def is_on(a, b, c):
    "Return true iff point c intersects the line segment from a to b."
    # (or the degenerate case that all 3 points are coincident)
    return (collinear(a, b, c)
            and (within(a.x, c.x, b.x) if a.x != b.x else 
                 within(a.y, c.y, b.y)))

def collinear(a, b, c):
    "Return true iff a, b, and c all lie on the same line."
    return (b.x - a.x) * (c.y - a.y) == (c.x - a.x) * (b.y - a.y)

def within(p, q, r):
    "Return true iff q is between p and r (inclusive)."
    return p <= q <= r or r <= q <= p

This answer used to be a mess of three updates. The worthwhile info from them: Brian Hayes's chapter in Beautiful Code covers the design space for a collinearity-test function -- useful background. Vincent's answer helped to improve this one. And it was Hayes who suggested testing only one of the x or the y coordinates; originally the code had and in place of if a.x != b.x else.

Since you are saying the webservice is not live right now, you can do it by creating mockservices which will create the sample response format.

SO...older thread, I know, but...

EDIT

@RoccoMusolino had a nice catch; here's an alternative:

TL;DR:

 const intArray = [...("5 6 7 69 foo 0".split(' ').filter(i => /\d/g.test(i)))]

WRONG: "5 6 note this foo".split(" ").map(Number).filter(Boolean); // [5, 6]

There is a subtle flaw in the more elegant solutions listed here, specifically @amillara and @Marcus' otherwise beautiful answers.

The problem occurs when an element of the string array isn't integer-like, perhaps in a case without validation on an input. For a contrived example...

The problem:

var effedIntArray = "5 6 7 69 foo".split(' ').map(Number); // [5, 6, 7, 69, NaN]

Since you obviously want a PURE int array, that's a problem. Honestly, I didn't catch this until I copy-pasted SO code into my script... :/

The (slightly-less-baller) fix:

var intArray = "5 6 7 69 foo".split(" ").map(Number).filter(Boolean); // [5, 6, 7, 69]

So, now even when you have crap int string, your output is a pure integer array. The others are really sexy in most cases, but I did want to offer my mostly rambly w'actually. It is still a one-liner though, to my credit...

Hope it saves someone time!

It looks necessary to put a SET IDENTITY_INSERT Database.dbo.Baskets ON; before every SQL INSERT sending batch.

You can send several INSERT ... VALUES ... commands started with one SET IDENTITY_INSERT ... ON; string at the beginning. Just don't put any batch separator between.

I don't know why the SET IDENTITY_INSERT ... ON stops working after the sending block (for ex.: .ExecuteNonQuery() in C#). I had to put SET IDENTITY_INSERT ... ON; again at the beginning of next SQL command string.

From ?read.table: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.

So, perhaps your data file isn't clean. Being more specific will help the data import:

d = read.table("foobar.txt", 
               sep="\t", 
               col.names=c("id", "name"), 
               fill=FALSE, 
               strip.white=TRUE)

will specify exact columns and fill=FALSE will force a two column data frame.

public void GetResponseAsync (HttpWebRequest request, Action<HttpWebResponse> gotResponse)
    {
        if (request != null) { 
            request.BeginGetRequestStream ((r) => {
                try { // there's a try/catch here because execution path is different from invokation one, exception here may cause a crash
                    HttpWebResponse response = request.EndGetResponse (r);
                    if (gotResponse != null) 
                        gotResponse (response);
                } catch (Exception x) {
                    Console.WriteLine ("Unable to get response for '" + request.RequestUri + "' Err: " + x);
                }
            }, null);
        } 
    }

Unless you have a specific reason not to, just use a normal object. Object properties in JavaScript can be referenced using hashtable-style syntax:

var hashtable = {};
hashtable.foo = "bar";
hashtable['bar'] = "foo";

Both foo and bar elements can now then be referenced as:

hashtable['foo'];
hashtable['bar'];

// Or
hashtable.foo;
hashtable.bar;

Of course this does mean your keys have to be strings. If they're not strings they are converted internally to strings, so it may still work. Your mileage may vary.

Numpy matrices are strictly 2-dimensional, while numpy arrays (ndarrays) are N-dimensional. Matrix objects are a subclass of ndarray, so they inherit all the attributes and methods of ndarrays.

The main advantage of numpy matrices is that they provide a convenient notation for matrix multiplication: if a and b are matrices, then a*b is their matrix product.

import numpy as np

a = np.mat('4 3; 2 1')
b = np.mat('1 2; 3 4')
print(a)
# [[4 3]
#  [2 1]]
print(b)
# [[1 2]
#  [3 4]]
print(a*b)
# [[13 20]
#  [ 5  8]]

On the other hand, as of Python 3.5, NumPy supports infix matrix multiplication using the @ operator, so you can achieve the same convenience of matrix multiplication with ndarrays in Python >= 3.5.

import numpy as np

a = np.array([[4, 3], [2, 1]])
b = np.array([[1, 2], [3, 4]])
print(a@b)
# [[13 20]
#  [ 5  8]]

Both matrix objects and ndarrays have .T to return the transpose, but matrix objects also have .H for the conjugate transpose, and .I for the inverse.

In contrast, numpy arrays consistently abide by the rule that operations are applied element-wise (except for the new @ operator). Thus, if a and b are numpy arrays, then a*b is the array formed by multiplying the components element-wise:

c = np.array([[4, 3], [2, 1]])
d = np.array([[1, 2], [3, 4]])
print(c*d)
# [[4 6]
#  [6 4]]

To obtain the result of matrix multiplication, you use np.dot (or @ in Python >= 3.5, as shown above):

print(np.dot(c,d))
# [[13 20]
#  [ 5  8]]

The ** operator also behaves differently:

print(a**2)
# [[22 15]
#  [10  7]]
print(c**2)
# [[16  9]
#  [ 4  1]]

Since a is a matrix, a**2 returns the matrix product a*a. Since c is an ndarray, c**2 returns an ndarray with each component squared element-wise.

There are other technical differences between matrix objects and ndarrays (having to do with np.ravel, item selection and sequence behavior).

The main advantage of numpy arrays is that they are more general than 2-dimensional matrices. What happens when you want a 3-dimensional array? Then you have to use an ndarray, not a matrix object. Thus, learning to use matrix objects is more work -- you have to learn matrix object operations, and ndarray operations.

Writing a program that mixes both matrices and arrays makes your life difficult because you have to keep track of what type of object your variables are, lest multiplication return something you don't expect.

In contrast, if you stick solely with ndarrays, then you can do everything matrix objects can do, and more, except with slightly different functions/notation.

If you are willing to give up the visual appeal of NumPy matrix product notation (which can be achieved almost as elegantly with ndarrays in Python >= 3.5), then I think NumPy arrays are definitely the way to go.

PS. Of course, you really don't have to choose one at the expense of the other, since np.asmatrix and np.asarray allow you to convert one to the other (as long as the array is 2-dimensional).

There is a synopsis of the differences between NumPy arrays vs NumPy matrixes here.

For this lint warning, as for all other lint warnings, note that you can get a fuller explanation than just what is in the one line error message; you don't have to search the web for more info.

If you are using lint via Eclipse, either open the lint warnings view, where you can select the lint error and see a longer explanation, or invoke the quick fix (Ctrl-1) on the error line, and one of the suggestions is "Explain this issue", which will also pop up a fuller explanation. If you are not using Eclipse, you can generate an HTML report from lint (lint --html <filename>) which includes full explanations next to the warnings, or you can ask lint to explain a particular issue. For example, the issue related to allowBackup has the id AllowBackup (shown at the end of the error message), so the fuller explanation is:

$ ./lint --show AllowBackup
AllowBackup
-----------
Summary: Ensure that allowBackup is explicitly set in the application's
manifest

Priority: 3 / 10
Severity: Warning
Category: Security

The allowBackup attribute determines if an application's data can be backed up and restored, as documented here.

By default, this flag is set to true. When this flag is set to true, application data can be backed up and restored by the user using adb backup and adb restore.

This may have security consequences for an application. adb backup allows users who have enabled USB debugging to copy application data off of the device. Once backed up, all application data can be read by the user. adb restore allows creation of application data from a source specified by the user. Following a restore, applications should not assume that the data, file permissions, and directory permissions were created by the application itself.

Setting allowBackup="false" opts an application out of both backup and restore.

To fix this warning, decide whether your application should support backup and explicitly set android:allowBackup=(true|false)

You can use the iOS simulator to do this. You need to enable "Developer Mode" on Safari (Preferences -> Advanced).

Then open the website you want to debug in the iOS simulator. Go back to safari and under Develop you will see the simulator and the tabs open on safari.

If you want to test an actual device, then just plug it into your computer and it should show there too.

That's how I do it.

The comprehensive place for Acrobat JavaScript documentation is the Acrobat SDK, which can be downloaded from the Adobe website. In the Documentation section, you will find all the material needed to work with Acrobat JavaScript.

To complete the documentation you may in addition get the specification of the JavaScript Core. My book of choice for that is "JavaScript, the Definitive Guide" by David Flanagan, published by O'Reilly.

First of all, you need to check that the IIS is installed in your machine, for that you can go to:

Control Panel --> Add or Remove Programs --> Windows Features --> And Check if Internet Information Services is installed with at least the 'Web Administration Tools' Enabled and The 'World Wide Web Service'

If not, check it, and Press Accept to install it.

Once that is done, you need to go to Administrative Tools in Control Panel and the IIS Will be there. Or simply run inetmgr (after Win+R).

Edit: You should have something like this:

Typically, you'd use the NODE_ENV variable to take special actions when you develop, test and debug your code. For example to produce detailed logging and debug output which you don't want in production. Express itself behaves differently depending on whether NODE_ENV is set to production or not. You can see this if you put these lines in an Express app, and then make a HTTP GET request to /error:

app.get('/error', function(req, res) {
  if ('production' !== app.get('env')) {
    console.log("Forcing an error!");
  }
  throw new Error('TestError');
});

app.use(function (req, res, next) {
  res.status(501).send("Error!")
})

Note that the latter app.use() must be last, after all other method handlers!

If you set NODE_ENV to production before you start your server, and then send a GET /error request to it, you should not see the text Forcing an error! in the console, and the response should not contain a stack trace in the HTML body (which origins from Express). If, instead, you set NODE_ENV to something else before starting your server, the opposite should happen.

In Linux, set the environment variable NODE_ENV like this:

export NODE_ENV='value'

You can use a post-commit hook.

Put the post-commit hook script in the hooks folder, create a wget_folder in your C:\ drive, and put the wget.exe file in this folder. Add the following code in the file called post-commit.bat

SET REPOS=%1   
SET REV=%2

FOR /f "tokens=*" %%a IN (  
'svnlook uuid %REPOS%'  
) DO (  
SET UUID=%%a  
)  

FOR /f "tokens=*" %%b IN (  
'svnlook changed --revision %REV% %REPOS%'  
) DO (  
SET POST=%%b   
)

echo %REPOS% ----- 1>&2

echo %REV% -- 1>&2

echo %UUID% --1>&2

echo %POST% --1>&2

C:\wget_folder\wget ^   
    --header="Content-Type:text/plain" ^   
    --post-data="%POST%" ^   
    --output-document="-" ^   
    --timeout=2 ^     
    http://localhost:9090/job/Test/build/%UUID%/notifyCommit?rev=%REV%    

where Test = name of the job

echo is used to see the value and you can also add exit 2 at the end to know about the issue and whether the post-commit hook script is running or not.

Use double quote to enclose the quote or escape it.

newTemp = mystring.replace(/"/g, "'");

or

newTemp = mystring.replace(/"/g, '\'');

Another way to consolidate font creation...

public class Font {
  public static final Font  PROXIMA_NOVA    = new Font("ProximaNovaRegular.otf");
  public static final Font  FRANKLIN_GOTHIC = new Font("FranklinGothicURWBoo.ttf");
  private final String      assetName;
  private volatile Typeface typeface;

  private Font(String assetName) {
    this.assetName = assetName;
  }

  public void apply(Context context, TextView textView) {
    if (typeface == null) {
      synchronized (this) {
        if (typeface == null) {
          typeface = Typeface.createFromAsset(context.getAssets(), assetName);
        }
      }
    }
    textView.setTypeface(typeface);
  }
}

And then to use in your activity...

myTextView = (TextView) findViewById(R.id.myTextView);
Font.PROXIMA_NOVA.apply(this, myTextView);

Mind you, this double-checked locking idiom with the volatile field only works correctly with the memory model used in Java 1.5+.

This is not possible. If you want to display text inside a rect element you should put them both in a group with the text element coming after the rect element ( so it appears on top ).

<svg xmlns="http://www.w3.org/2000/svg">_x000D_
  <g>_x000D_
    <rect x="0" y="0" width="100" height="100" fill="red"></rect>_x000D_
    <text x="0" y="50" font-family="Verdana" font-size="35" fill="blue">Hello</text>_x000D_
  </g>_x000D_
</svg>

Try this:

Edit or create the file :nodesource.list

sudo gedit /etc/apt/sources.list.d/nodesource.list

Insert this text:

deb https://deb.nodesource.com/node_10.x bionic main

deb-src https://deb.nodesource.com/node_10.x bionic main

Run these commands:

curl -s https://deb.nodesource.com/gpgkey/nodesource.gpg.key | apt-key add -


sudo sh -c "echo deb https://deb.nodesource.com/node_10.x cosmic main /etc/apt/sources.list.d/nodesource.list"

sudo apt-get update

sudo apt-get install nodejs

You can use "track by" to increase the performance:

<div ng-repeat="a in arr track by a.trackingKey">

Faster than:

<div ng-repeat="a in arr">

By definition, a UUID is 32 hexadecimal digits, separated in 5 groups by hyphens, just as you have described. You shouldn't miss any with your regular expression.

http://en.wikipedia.org/wiki/Uuid#Definition

Here are the approximate zoom levels and what they do :

1: World
5: Landmass/continent
10: City
15: Streets
20: Buildings

so you could do something like this to zoom to street level for example (note the "15f" below is street level) :

 override fun onMapReady(googleMap: GoogleMap?) {
    googleMap?.mapType = GoogleMap.MAP_TYPE_NORMAL
    googleMap?.addMarker(MarkerOptions()
            .position(LatLng(37.4233438, -122.0728817))
            .title("cool place")

            .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ROSE)))

    googleMap?.animateCamera(CameraUpdateFactory.newLatLngZoom(LatLng(37.4233438, -122.0728817), 15f))

note: just so you know different locations can have different max zoom levels. try to use googleMap.maxZoomLevel if you want to get the max or min zoom levels.

I face this issue for the second time and all previous answers failed, fortunately the following request do the job:

Alter login [user] with CHECK_POLICY = OFF

Heres another way of working this out from using the bash command line.

The docs for the spinner-widget says

A spinner does not support item click events.

You should use setOnItemSelectedListener to handle your problem.

String.prototype.interpole = function () {
    var c=0, txt=this;
    while (txt.search(/{var}/g) > 0){
        txt = txt.replace(/{var}/, arguments[c]);
        c++;
    }
    return txt;
}

Uso:

var hello = "foo";
var my_string = "I pity the {var}".interpole(hello);
//resultado "I pity the foo"

I just tried below package for php v5.6 and it worked for me.

yum install php56w-bcmath

Try this:

pointer-events:none

Adding above on the specified HTML element will prevents all click, state and cursor options.

http://jsfiddle.net/4hrpsrnp/

<div class="ads">
 <button id='noclick' onclick='clicked()'>Try</button>
</div>

You can actually detect when the old modal closes by calling the hidden.bs.modal event:

    $('.yourButton').click(function(e){
        e.preventDefault();

        $('#yourFirstModal')
            .modal('hide')
            .on('hidden.bs.modal', function (e) {
                $('#yourSecondModal').modal('show');

                $(this).off('hidden.bs.modal'); // Remove the 'on' event binding
            });

    });

Use vh attributes. It means viewport height and is a percentage. So height: 90vh would mean 90% of the viewport height. This works in most modern browsers.

Eg.

div {
  height: 90vh;
}

You can forego the rest of your silly 100% stuff on the body.

If you have a header you can also do some fun things like take it into account by using the calc function in CSS.

Eg.

div {
  height: calc(100vh - 50px);
}

This will give you 100% of the viewport height, minus 50px for your header.

To get your current location as start point you need to use this URL:

https://www.google.com/maps/dir/?api=1&origin=Current+Location&destination=<latitude>,<longitude>

You can fill up the destination parameter with the address, name or latitude and longitude values.

Python convert radians to degrees or degrees to radians:

What are Radians and what problem does it solve?:

Radians and degrees are two separate units of measure that help people express and communicate precise changes in direction. Wikipedia has some great intuition with their infographics on how one Radian is defined relative to degrees:

https://en.wikipedia.org/wiki/Radian

Python examples using libraries calculating degrees from radians:

>>> import math
>>> math.degrees(0)                       #0 radians == 0 degrees
0.0
>>> math.degrees(math.pi/2)               #pi/2 radians is 90 degrees
90.0
>>> math.degrees(math.pi)                 #pi radians is 180 degrees
180.0      
>>> math.degrees(math.pi+(math.pi/2))     #pi+pi/2 radians is 270 degrees
270.0 
>>> math.degrees(math.pi+math.pi)         #2*pi radians is 360 degrees
360.0      

Python examples using libraries calculating radians from degrees:

>>> import math
>>> math.radians(0)           #0 degrees == 0 radians
0.0
>>> math.radians(90)          #90 degrees is pi/2 radians
1.5707963267948966
>>> math.radians(180)         #180 degrees is pi radians
3.141592653589793
>>> math.radians(270)         #270 degrees is pi+(pi/2) radians
4.71238898038469
>>> math.radians(360)         #360 degrees is 2*pi radians
6.283185307179586

Source: https://docs.python.org/3/library/math.html#angular-conversion

The mathematical notation:

You can do degree/radian conversion without libraries:

If you roll your own degree/radian converter, you have to write your own code to handle edge cases.

Mistakes here are easy to make, and will hurt just like it hurt the developers of the 1999 mars orbiter who sunk $125m dollars crashing it into Mars because of non intuitive edge cases here.

Lets crash that orbiter and Roll our own Radians to Degrees:

Invalid radians as input return garbage output.

>>> 0 * 180.0 / math.pi                         #0 radians is 0 degrees
0.0
>>> (math.pi/2) * 180.0 / math.pi               #pi/2 radians is 90 degrees
90.0
>>> (math.pi) * 180.0 / math.pi                 #pi radians is 180 degrees
180.0
>>> (math.pi+(math.pi/2)) * 180.0 / math.pi     #pi+(pi/2) radians is 270 degrees
270.0
>>> (2 * math.pi) * 180.0 / math.pi             #2*pi radians is 360 degrees
360.0

Degrees to radians:

>>> 0 * math.pi / 180.0              #0 degrees in radians
0.0
>>> 90 * math.pi / 180.0             #90 degrees in radians
1.5707963267948966
>>> 180 * math.pi / 180.0            #180 degrees in radians
3.141592653589793
>>> 270 * math.pi / 180.0            #270 degrees in radians
4.71238898038469
>>> 360 * math.pi / 180.0            #360 degrees in radians
6.283185307179586

Expressing multiple rotations with degrees and radians

Single rotation valid radian values are between 0 and 2*pi. Single rotation degree values are between 0 and 360. However if you want to express multiple rotations, valid radian and degree values are between 0 and infinity.

>>> import math
>>> math.radians(360)                 #one complete rotation
6.283185307179586
>>> math.radians(360+360)             #two rotations
12.566370614359172
>>> math.degrees(12.566370614359172)  #math.degrees and math.radians preserve the
720.0                                 #number of rotations

Collapsing multiple rotations:

You can collapse multiple degree/radian rotations into a single rotation by modding against the value of one rotation. For degrees you mod by 360, for radians you modulus by 2*pi.

>>> import math
>>> math.radians(720+90)        #2 whole rotations plus 90 is 14.14 radians
14.137166941154069
>>> math.radians((720+90)%360)  #14.1 radians brings you to 
1.5707963267948966              #the end point as 1.57 radians.

>>> math.degrees((2*math.pi)+(math.pi/2))            #one rotation plus a quarter 
450.0                                                #rotation is 450 degrees.
>>> math.degrees(((2*math.pi)+(math.pi/2))%(2*math.pi)) #one rotation plus a quarter
90.0                                                    #rotation brings you to 90.

Web Hosting Challenge

You have to remember that none of the machine configuration options are available if you are hosted on a shared server as many of us (smaller companies and individuals) are.

ASP.NET MVC Overhead

My site takes at least 30 seconds when it hasn't been hit in over 20 minutes (and the web app has been stopped). It is terrible.

Another Way to Test Performance

There's another way to test if it is your ASP.NET MVC start up or something else. Drop a normal HTML page on your site where you can hit it directly.
If the problem is related to ASP.NET MVC start up then the HTML page will render almost immediately even when the web app hasn't been started.
That's how I first recognized that the problem was in the ASP.NET MVC startup. I loaded an HTML page at any time and it would load blazing fast. Then, after hitting that HTML page I'd hit one of my ASP.NET MVC URLs and I'd get the Chrome message "Waiting for raddev.us..."

Another Test With Helpful Script

After that I wrote a LINQPad (check out http://linqpad.net for more) script that would hit my web site every 8 minutes (less than the time for the app to unload -- which should be 20 minutes) and I let it run for hours.

While the script was running I hit my web site and every time my site came up blazingly fast. This gives me a good idea that most likely the slowness I was experiencing was because of ASP.NET MVC startup times.

Get LinqPad and you can run the following script -- just change the URL to your own and let it run and you can test this easily. Good luck.

NOTE: In LinqPad you'll need to press F4 and add a reference to System.Net to add the library which will retrieve your page.

ALSO : make sure you change the String URL variable to point at a URL that will load a route from your ASP.NET MVC site so the engine will run.

System.Timers.Timer webKeepAlive = new System.Timers.Timer();
Int64 counter = 0;
void Main()
{
    webKeepAlive.Interval = 5000;
    webKeepAlive.Elapsed += WebKeepAlive_Elapsed;
    webKeepAlive.Start();
}

private void WebKeepAlive_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    webKeepAlive.Stop();
    try
    {
        // ONLY the first time it retrieves the content it will print the string
        String finalHtml = GetWebContent();
        if (counter < 1)
        {
            Console.WriteLine(finalHtml);
        }
        counter++;
    }
    finally
    {
        webKeepAlive.Interval = 480000; // every 8 minutes
        webKeepAlive.Start();
    }
}

public String GetWebContent()
{
    try
    {
    String URL = "http://YOURURL.COM";
    WebRequest request = WebRequest.Create(URL);
    WebResponse response = request.GetResponse();
    Stream data = response.GetResponseStream();
    string html = String.Empty;
    using (StreamReader sr = new StreamReader(data))
    {
        html = sr.ReadToEnd();
    }
    Console.WriteLine (String.Format("{0} : success",DateTime.Now));
    return html;
    }
    catch (Exception ex)
    {
        Console.WriteLine (String.Format("{0} -- GetWebContent() : {1}",DateTime.Now,ex.Message));
        return "fail";
    }
}

Not always there's a servlet before of an upload (I could use a filter for example). Or could be that the same controller ( again a filter or also a servelt ) can serve many actions, so I think that rely on that servlet configuration to use the getPart method (only for Servlet API >= 3.0), I don't know, I don't like.

In general, I prefer independent solutions, able to live alone, and in this case http://commons.apache.org/proper/commons-fileupload/ is one of that.

List<FileItem> multiparts = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
    for (FileItem item : multiparts) {
        if (!item.isFormField()) {
            //your operations on file
        } else {
            String name = item.getFieldName();
            String value = item.getString();
            //you operations on paramters
        }
}

You can also hard code in the dimensions in your html code as opposed to putting the desired dimensions in a style sheet

<div id="mainDiv">
    <div id="mydiv" style="height:150px; width:150px;">
    </div>
</div>

Here goes a straightforward example:

# Do something, or tell me why it failed
my_update_function <- function(x){
    tryCatch(
        # This is what I want to do...
        {
        y = x * 2
        return(y)
        },
        # ... but if an error occurs, tell me what happened: 
        error=function(error_message) {
            message("This is my custom message.")
            message("And below is the error message from R:")
            message(error_message)
            return(NA)
        }
    )
}

If you also want to capture a "warning", just add warning= similar to the error= part.

Here's how I would do it:

if (Object.prototype.toString.call(d) === "[object Date]") {
  // it is a date
  if (isNaN(d.getTime())) {  // d.valueOf() could also work
    // date is not valid
  } else {
    // date is valid
  }
} else {
  // not a date
}

Update [2018-05-31]: If you are not concerned with Date objects from other JS contexts (external windows, frames, or iframes), this simpler form may be preferred:

function isValidDate(d) {
  return d instanceof Date && !isNaN(d);
}

You want something like:

<button class="btn btn-primary btn-block" onclick="this.blur();">...

The .blur() method correctly removes the focus highlighting and doesn't mess up Bootstraps's styles.

According to the curl man page:

You can specify any amount of URLs on the command line. They will be fetched in a sequential manner in the specified order.

So the simplest and most efficient (curl will send them all down a single TCP connection [those to the same origin]) approach would be put them all on a single invocation of curl e.g.:

curl http://example.com/?update_=1 http://example.com/?update_=2

How about writing a custom attribute:

public class LocalizedDisplayNameAttribute: DisplayNameAttribute
{
    public LocalizedDisplayNameAttribute(string resourceId) 
        : base(GetMessageFromResource(resourceId))
    { }

    private static string GetMessageFromResource(string resourceId)
    {
        // TODO: Return the string from the resource file
    }
}

which could be used like this:

public class MyModel 
{
    [Required]
    [LocalizedDisplayName("labelForName")]
    public string Name { get; set; }
}

Transient variables in Java are never serialized.

Try this

function setAttribs(elm, ob) {
    //var r = [];
    //var i = 0;
    for (var z in ob) {
        if (ob.hasOwnProperty(z)) {
            try {
                elm[z] = ob[z];
            }
            catch (er) {
                elm.setAttribute(z, ob[z]);
            }
        }
    }
    return elm;
}

For all those 'rU' filemode haters: I just tried opening a CSV file from a Windows machine on a Mac with the 'rb' filemode and I got this error from the csv module:

Error: new-line character seen in unquoted field - do you need to 
open the file in universal-newline mode?

Opening the file in 'rU' mode works fine. I love universal-newline mode -- it saves me so much hassle.

Joda-Time

Since many of the answers required API 26 support and my min API was 23, I solved it by below code :

import org.joda.time.Days

LocalDate startDate = Something
LocalDate endDate = Something
// The difference would be exclusive of both dates, 
// so in most of use cases we may need to increment it by 1
Days.daysBetween(startDate, endDate).days

If you or some other fox who need to have link with Icon Image and text as link text beside the image see bellow code:

CSS

.linkWithImageIcon{

    Display:inline-block;
}
.MyLink{
  Background:#FF3300;
  width:200px;
  height:70px;
  vertical-align:top;
  display:inline-block; font-weight:bold;
} 

.MyLinkText{
  /*---The margin depends on how the image size is ---*/
  display:inline-block; margin-top:5px;
}

HTML

<a href="#" class="MyLink"><img src="./yourImageIcon.png" /><span class="MyLinkText">SIGN IN</span></a>

if you see the image the white portion is image icon and other is style this way you can create different buttons with any type of Icons you want to design

<input type="text" autocomplete="off"/>

Should work. Alternatively, use:

<form autocomplete="off" … >

for the entire form (see this related question).

Yes, you can set cookie in the AJAX request in the server-side code just as you'd do for a normal request since the server cannot differentiate between a normal request or an AJAX request.

AJAX requests are just a special way of requesting to server, the server will need to respond back as in any HTTP request. In the response of the request you can add cookies.

Not possible in just grep I believe

for sed:

name=`echo $f | sed -E 's/([0-9]+_([a-z]+)_[0-9a-z]*)|.*/\2/'`

I'll take a stab at the bonus though:

echo "$name.jpg"

Contrary to what cularis said there can be both in the parameter map.

The best way I see is to proxy the parameterMap and for each parameter retrieval check if queryString contains "&?<parameterName>=".

Note that parameterName needs to be URL encoded before this check can be made, as Qerub pointed out.

That saves you the parsing and still gives you only URL parameters.

I created a function for a Volley Request. You just need to pass the arguments :

public void callvolly(final String username, final String password){
    RequestQueue MyRequestQueue = Volley.newRequestQueue(this);
    String url = "http://your_url.com/abc.php"; // <----enter your post url here
    StringRequest MyStringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            //This code is executed if the server responds, whether or not the response contains data.
            //The String 'response' contains the server's response.
        }
    }, new Response.ErrorListener() { //Create an error listener to handle errors appropriately.
        @Override
        public void onErrorResponse(VolleyError error) {
            //This code is executed if there is an error.
        }
    }) {
        protected Map<String, String> getParams() {
            Map<String, String> MyData = new HashMap<String, String>();
            MyData.put("username", username);             
            MyData.put("password", password);                
            return MyData;
        }
    };


    MyRequestQueue.add(MyStringRequest);
}

You don't directly read a value. You can set it with .setValue(), but there is no .getValue() on the reference object.

You have to use a listener. If you just want to read the value once, you use ref.addListenerForSingleValueEvent().

Example:

Firebase ref = new Firebase("YOUR-URL-HERE/PATH/TO/YOUR/STUFF");
ref.addListenerForSingleValueEvent(new ValueEventListener() {
   @Override
   public void onDataChange(DataSnapshot dataSnapshot) {
       String value = (String) dataSnapshot.getValue();

       // do your stuff here with value

   }

   @Override
   public void onCancelled(FirebaseError firebaseError) {

   }
});

Here's a simple single threaded sleep based version that drifts, but tries to auto-correct when it detects drift.

NOTE: This will only work if the following 3 reasonable assumptions are met:

1. The time period is much larger than the execution time of the function being executed
2. The function being executed takes approximately the same amount of time on each call
3. The amount of drift between calls is less than a second

-

from datetime import timedelta
from datetime import datetime

def exec_every_n_seconds(n,f):
    first_called=datetime.now()
    f()
    num_calls=1
    drift=timedelta()
    time_period=timedelta(seconds=n)
    while 1:
        time.sleep(n-drift.microseconds/1000000.0)
        current_time = datetime.now()
        f()
        num_calls += 1
        difference = current_time - first_called
        drift = difference - time_period* num_calls
        print "drift=",drift

Try following source code it worked for me

//Fetching id from shared preferences
    SharedPreferences sharedPreferences;
    sharedPreferences =getSharedPreferences(Constant.SHARED_PREF_NAME, Context.MODE_PRIVATE);
    getUserLogin = sharedPreferences.getString(Constant.ID_SHARED_PREF, "");

Simply add this in your layout for the EditText :

android:textColorHint="#FFFFFF"

I prefer following approach (code below). It solves the "namespace pollution" problem, but also it is much more typesafe (you can't assign and even compare two different enumerations, or your enumeration with any other built-in types etc).

struct Color
{
    enum Type
    {
        Red, Green, Black
    };
    Type t_;
    Color(Type t) : t_(t) {}
    operator Type () const {return t_;}
private:
   //prevent automatic conversion for any other built-in types such as bool, int, etc
   template<typename T>
    operator T () const;
};

Usage:

Color c = Color::Red;
switch(c)
{
   case Color::Red:
     //????????? ???
   break;
}
Color2 c2 = Color2::Green;
c2 = c; //error
c2 = 3; //error
if (c2 == Color::Red ) {} //error
If (c2) {} error

I create macro to facilitate usage:

#define DEFINE_SIMPLE_ENUM(EnumName, seq) \
struct EnumName {\
   enum type \
   { \
      BOOST_PP_SEQ_FOR_EACH_I(DEFINE_SIMPLE_ENUM_VAL, EnumName, seq)\
   }; \
   type v; \
   EnumName(type v) : v(v) {} \
   operator type() const {return v;} \
private: \
    template<typename T> \
    operator T () const;};\

#define DEFINE_SIMPLE_ENUM_VAL(r, data, i, record) \
    BOOST_PP_TUPLE_ELEM(2, 0, record) = BOOST_PP_TUPLE_ELEM(2, 1, record),

Usage:

DEFINE_SIMPLE_ENUM(Color,
             ((Red, 1))
             ((Green, 3))
             )

After some digging and I ended up setting Thread's CurrentCulture value to have CultureInfo("en-US") in the controller’s action method:

Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US"); 

Here are some other options if you want have this setting on every view.

About CurrentCulture property value:

The CultureInfo object that is returned by this property, together with its associated objects, determine the default format for dates, times, numbers, currency values, the sorting order of text, casing conventions, and string comparisons.

Source: MSDN CurrentCulture

Note: The previous CurrentCulture property setting is probably optional if the controller is already running with CultureInfo("en-US") or similar where the date format is "MM/dd/yyyy".

After setting the CurrentCulture property, add code block to convert the date to "M/d/yyyy" format in the view:

@{  //code block 
    var shortDateLocalFormat = "";
    if (Model.AuditDate.HasValue) {
       shortDateLocalFormat = ((DateTime)Model.AuditDate).ToString("M/d/yyyy");
       //alternative way below
       //shortDateLocalFormat = ((DateTime)Model.AuditDate).ToString("d");
    }
}

@shortDateLocalFormat

Above the @shortDateLocalFormat variable is formatted with ToString("M/d/yyyy") works. If ToString("MM/dd/yyyy") is used, like I did first then you end up having leading zero issue. Also like recommended by Tommy ToString("d") works as well. Actually "d" stands for “Short date pattern” and can be used with different culture/language formats too.

I guess the code block from above can also be substituted with some cool helper method or similar.

For example

@helper DateFormatter(object date)
{
    var shortDateLocalFormat = "";
    if (date != null) {     
        shortDateLocalFormat = ((DateTime)date).ToString("M/d/yyyy");
     }

    @shortDateLocalFormat
}

can be used with this helper call

@DateFormatter(Model.AuditDate)

Update, I found out that there’s alternative way of doing the same thing when DateTime.ToString(String, IFormatProvider) method is used. When this method is used then there’s no need to use Thread’s CurrentCulture property. The CultureInfo("en-US") is passed as second argument --> IFormatProvider to DateTime.ToString(String, IFormatProvider) method.

Modified helper method:

@helper DateFormatter(object date)
{
    var shortDateLocalFormat = "";
    if (date != null) {
       shortDateLocalFormat = ((DateTime)date).ToString("d", new System.Globalization.CultureInfo("en-US"));
    }

    @shortDateLocalFormat
}

.NET Fiddle

Please see https://github.com/joshua-gould/canvas2pdf. This library creates a PDF representation of your canvas element, unlike the other proposed solutions which embed an image in a PDF document.

//Create a new PDF canvas context.
var ctx = new canvas2pdf.Context(blobStream());

//draw your canvas like you would normally
ctx.fillStyle='yellow';
ctx.fillRect(100,100,100,100);
// more canvas drawing, etc...

//convert your PDF to a Blob and save to file
ctx.stream.on('finish', function () {
    var blob = ctx.stream.toBlob('application/pdf');
    saveAs(blob, 'example.pdf', true);
});
ctx.end();

int firstDigit = Integer.parseInt(Character.toString(firstLetterChar));

What about this:

from operator import itemgetter
itemgetter(0,2,3)(myList)
('foo', 'baz', 'quux')

You should use the background attribute to give an image to that element, and I would use ::after instead of before, this way it should be already drawn on top of your element.

.Modal:before{
  content: '';
  background:url('blackCarrot.png');
  width: /* width of the image */;
  height: /* height of the image */;
  display: block;
}

event.target to get the element

window.onclick = e => {
    console.log(e.target);  // to get the element
    console.log(e.target.tagName);  // to get the element tag name alone
} 

to get the text from clicked element

window.onclick = e => {
    console.log(e.target.innerText);
} 

1. Will "length" ever deviate from the real length of "s". If the answer is no, then you don't need to store length, because strings store their length already, and you can just call s.Length.

2. To get the syntax you asked for, you can implement an "implicit" operator like so:

   static implicit operator MyStruct(string s) {
       return new MyStruct(...);
   }
   

3. The implicit operator will work, regardless of whether you make your struct mutable or not.

I got it solved by adding "-lc++" in Other Linker Flags in Build Settings.

Assuming that you meant to write

char *functionname(char *string[256])

Here you are declaring a function that takes an array of 256 pointers to char as argument and returns a pointer to char. Here, on the other hand,

char functionname(char string[256])

You are declaring a function that takes an array of 256 chars as argument and returns a char.

In other words the first function takes an array of strings and returns a string, while the second takes a string and returns a character.

Simple math:

    log₂ (x) = log_y (x) / log_y (2)

where y can be anything, which for standard log functions is either 10 or e.

You need to add the Host parameter

$mail->Host = "ssl://smtp.gmail.com"; 

Also, check if you have open_ssl enabled.

To keep the changes from the commit you want to undo

git reset --soft HEAD^

To destroy the changes from the commit you want to undo

git reset --hard HEAD^

You can also say

git reset --soft HEAD~2

to go back 2 commits.

Edit: As charsi mentioned, if you are on Windows you will need to put HEAD or commit hash in quotes.

git reset --soft "HEAD^"
git reset --soft "asdf"

There may be other ways to get your desired result.

Declare @a int
Declare @b int
SET @a = 3
SET @b=2
SELECT cast((cast(@a as float)/ cast(@b as float)) as float)

The most versatile and most cross-browser solution is to avoid use of the "base" tag, and instead use the target attribute of the "a" tags:

<a target="_parent" href="http://www.stackoverflow.com">Stack Overflow</a>

The <base> tag is less versatile and browsers are inconsistent in their requirements for its placement within the document, requiring more cross-browser testing. Depending on your project and situation, it can be difficult or even totally unfeasible to achieve the ideal cross-browser placement of the <base> tag.

Doing this with the target="_parent" attribute of the <a> tag is not only more browser-friendly, but also allows you to distinguish between those links you want to open in the iframe, and those you want to open in the parent.

In error situations, I wanted to return a specific error details class, in whatever format the client requested instead of the happy path object.

I want to have my controller methods return the domain specific happy path object and to throw an exception otherwise.

The problem I had was that the HttpResponseException constructors do not allow domain objects.

This is what I eventually came up with

public ProviderCollection GetProviders(string providerName)
{
   try
   {
      return _providerPresenter.GetProviders(providerName);
   }
   catch (BadInputValidationException badInputValidationException)
   {
     throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.BadRequest,
                                          badInputValidationException.Result));
   }
}

Result is a class that contains error details, while ProviderCollection is my happy path result.

Just use window.open() function? The third parameter lets you specify window size.

Example

var strWindowFeatures = "location=yes,height=570,width=520,scrollbars=yes,status=yes";
var URL = "https://www.linkedin.com/cws/share?mini=true&url=" + location.href;
var win = window.open(URL, "_blank", strWindowFeatures);

}
</script><script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>

Just be careful of Bitmap type from java platform call like from comm1x's and Gnzlt's answers, because it might return null. I think it is also more flexible if the parameter can be any Number and use infix for readability, depends on your coding style.

infix fun Bitmap.rotate(degrees: Number): Bitmap? {
    return Bitmap.createBitmap(
        this,
        0,
        0,
        width,
        height,
        Matrix().apply { postRotate(degrees.toFloat()) },
        true
    )
}

How to use?

bitmap rotate 90
// or
bitmap.rotate(90)

Update Oct 2020:

So if you are on this page scratching your head why my favicon is not working , then read along. I tried all the things (which I supposedly thought I was doing right) yet favicon was not showing up on browser tabs.

Here is one line simple cracker code that worked flawlessly:

<link rel="icon" href="https://abcde.neocities.org/bla123.jpg" size="16x16" type="image/jpg">

Notes:

1. Put the image in the ROOT folder ( In one of my unsuccessful attempts , I was not using root dir)
2. Use direct favicon url link ( instead of href="images/bla123.jpg").
3. I placed this tag just below the <title> tag in the <Header>
4. I made the favicon size 64x64 px and size was 2.16 KB

I tested it on Firefox, Chrome, Edge, and opera. OS: Win 10, Mac OSX, ios and Android .Also I did not experience any cashing issues, worked pretty much as soon as I refreshed the page.

You're applying transitions only to the :hover pseudo-class, and not to the element itself.

.item {   
  height:200px;
  width:200px;
  background:red; 
  -webkit-transition: opacity 1s ease-in-out;
  -moz-transition: opacity 1s ease-in-out;
  -ms-transition: opacity 1s ease-in-out;
  -o-transition: opacity 1s ease-in-out;
  transition: opacity 1s ease-in-out;
}

.item:hover {
  zoom: 1;
  filter: alpha(opacity=50);
  opacity: 0.5;
}

Demo: http://jsfiddle.net/7uR8z/6/

If you don't want the transition to affect the mouse-over event, but only mouse-out, you can turn transitions off for the :hover state :

.item:hover {
  -webkit-transition: none;
  -moz-transition: none;
  -ms-transition: none;
  -o-transition: none;
  transition: none;
  zoom: 1;
  filter: alpha(opacity=50);
  opacity: 0.5;
}

for people who want to use UIDatePicker as input:

UIDatePicker *timePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 250, 0, 0)];
[timePicker addTarget:self action:@selector(pickerChanged:)

[_textField setInputView:timePicker];

// pickerChanged:

    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"d/M/Y"];
    _textField.text = [formatter stringFromDate:[sender date]];

A thread dump is a dump of the stacks of all live threads. Thus useful for analysing what an app is up to at some point in time, and if done at intervals handy in diagnosing some kinds of 'execution' problems (e.g. thread deadlock).

A heap dump is a dump of the state of the Java heap memory. Thus useful for analysing what use of memory an app is making at some point in time so handy in diagnosing some memory issues, and if done at intervals handy in diagnosing memory leaks.

This is what they are in 'raw' terms, and could be provided in many ways. In general used to describe dumped files from JVMs and app servers, and in this form they are a low level tool. Useful if for some reason you can't get anything else, but you will find life easier using decent profiling tool to get similar but easier to dissect info.

With respect to WebSphere a javacore file is a thread dump, albeit with a lot of other info such as locks and loaded classes and some limited memory usage info, and a PHD file is a heap dump.

If you want to read a javacore file you can do so by hand, but there is an IBM tool (BM Thread and Monitor Dump Analyzer) which makes it simpler. If you want to read a heap dump file you need one of many IBM tools: MDD4J or Heap Analyzer.

You could also check out paramiko. There's no scp module (yet), but it fully supports sftp.

[EDIT] Sorry, missed the line where you mentioned paramiko. The following module is simply an implementation of the scp protocol for paramiko. If you don't want to use paramiko or conch (the only ssh implementations I know of for python), you could rework this to run over a regular ssh session using pipes.

scp.py for paramiko

you can populate the data you want with a simple callback function, let's say we have a list named lst that we want to populate, we have a function that pupulates pupulates list,

const lst = [];  
const populateData = (data) => {lst.push(data)} 

now we can pass the callback function to the function which is making the axios call and we can pupulate the list when we get data from response.

now we make our function that makes the request and pass populateData as a callback function.

function axiosTest (populateData) {
        axios.get(url)
       .then(function(response){
               populateData(response.data);
        })
        .catch(function(error){
               console.log(error);
         });
}   

I realize this question was asked a long time ago, but I came here looking for answers and wasn't satisfied with anything I could find. I finally found the answer here:

https://www.tutorialsteacher.com/mvc/htmlhelper-dropdownlist-dropdownlistfor

To get the results from the form, use the FormCollection and then pull each individual value out by it's model name thus:

yourRecord.FieldName = Request.Form["FieldNameInModel"];

As far as I could tell it makes absolutely no difference what argument name you give to the FormCollection - use Request.Form["NameFromModel"] to retrieve it.

No, I did not dig down to see how th4e magic works under the covers. I just know it works...

I hope this helps somebody avoid the hours I spent trying different approaches before I got it working.

Keep it simple

dataGridView1.Columns.Add("newColumnName", "Column Name in Text");

To add rows

dataGridView1.Rows.Add("Value for column#1"); // [,"column 2",...]

There are many ways to address your problem.

1. First one as accepted answer by @robert. Here is the generalised solution for it:

def multi_dimensional_list(value, *args):
  #args dimensions as many you like. EG: [*args = 4,3,2 => x=4, y=3, z=2]
  #value can only be of immutable type. So, don't pass a list here. Acceptable value = 0, -1, 'X', etc.
  if len(args) > 1:
    return [ multi_dimensional_list(value, *args[1:]) for col in range(args[0])]
  elif len(args) == 1: #base case of recursion
    return [ value for col in range(args[0])]
  else: #edge case when no values of dimensions is specified.
    return None

Eg:

>>> multi_dimensional_list(-1, 3, 4)  #2D list
[[-1, -1, -1, -1], [-1, -1, -1, -1], [-1, -1, -1, -1]]
>>> multi_dimensional_list(-1, 4, 3, 2)  #3D list
[[[-1, -1], [-1, -1], [-1, -1]], [[-1, -1], [-1, -1], [-1, -1]], [[-1, -1], [-1, -1], [-1, -1]], [[-1, -1], [-1, -1], [-1, -1]]]
>>> multi_dimensional_list(-1, 2, 3, 2, 2 )  #4D list
[[[[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]]], [[[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]]]]

P.S If you are keen to do validation for correct values for args i.e. only natural numbers, then you can write a wrapper function before calling this function.

2. Secondly, any multidimensional dimensional array can be written as single dimension array. This means you don't need a multidimensional array. Here are the function for indexes conversion:

def convert_single_to_multi(value, max_dim):
  dim_count = len(max_dim)
  values = [0]*dim_count
  for i in range(dim_count-1, -1, -1): #reverse iteration
    values[i] = value%max_dim[i]
    value /= max_dim[i]
  return values


def convert_multi_to_single(values, max_dim):
  dim_count = len(max_dim)
  value = 0
  length_of_dimension = 1
  for i in range(dim_count-1, -1, -1): #reverse iteration
    value += values[i]*length_of_dimension
    length_of_dimension *= max_dim[i]
  return value

Since, these functions are inverse of each other, here is the output:

>>> convert_single_to_multi(convert_multi_to_single([1,4,6,7],[23,45,32,14]),[23,45,32,14])
[1, 4, 6, 7]
>>> convert_multi_to_single(convert_single_to_multi(21343,[23,45,32,14]),[23,45,32,14])
21343

3. If you are concerned about performance issues then you can use some libraries like pandas, numpy, etc.

Not orthodox, but it works for me sometimes; set your comment as another attribute:

<node usefulAttr="foo" comment="Your comment here..."/>

The accepted solution wasn't working. Chrome was printing a blank page because it wasn't loading the image in time. This approach works:

Edit: It appears the accepted solution was modified after my post. Why the downvote? This solution works as well.

    function printDiv(divName) {

        var printContents = document.getElementById(divName).innerHTML;
        w = window.open();

        w.document.write(printContents);
        w.document.write('<scr' + 'ipt type="text/javascript">' + 'window.onload = function() { window.print(); window.close(); };' + '</sc' + 'ript>');

        w.document.close(); // necessary for IE >= 10
        w.focus(); // necessary for IE >= 10

        return true;
    }

Another option would be to set a flag variable as a Boolean and then change that value based on your criteria.

Dim count as Integer 
Dim flag as Boolean

flag = True

While flag
    count = count + 1 

    If count = 10 Then
        'Set the flag to false         '
        flag = false
    End If 
Wend

I use this:

basename $(git remote get-url origin) .git

Which returns something like gitRepo. (Remove the .git at the end of the command to return something like gitRepo.git.)

(Note: It requires Git version 2.7.0 or later)

I may be slightly off-topic as you did mention the need for a username and password, and my understanding of the issue is admitedly not the best but is OpenID something worth considering?

If you use OpenID then you don't end up storing any credentials at all if I understand the technology correctly and users can use credentials that they already have, avoiding the need to create a new identity that is specific to your application.

It may not be suitable if the application in question is purely for internal use though

RPX provides a nice easy way to intergrate OpenID support into an application.

You just need to create your own class inherited from parent. Place an ImageView on that, and on the mousedown and mouse up events just change the images of the ImageView.

public class ImageButton extends Parent {

    private static final Image NORMAL_IMAGE = ...;
    private static final Image PRESSED_IMAGE = ...;

    private final ImageView iv;

    public ImageButton() {
        this.iv = new ImageView(NORMAL_IMAGE);
        this.getChildren().add(this.iv);

        this.iv.setOnMousePressed(new EventHandler<MouseEvent>() {

            public void handle(MouseEvent evt) {
                iv.setImage(PRESSED_IMAGE);
            }

        });

        // TODO other event handlers like mouse up

    } 

}

Simple example using a class :

class test {

    public function works($other_parameter, $function_as_parameter)
    {

        return $function_as_parameter($other_parameter) ;

    }

}

$obj = new test() ;

echo $obj->works('working well',function($other_parameter){


    return $other_parameter;


});

On mac OS X Yosemite, after installing it with brew it put it into

/usr/local/opt/openssl/bin/openssl

But kept getting an error "Linking keg-only openssl means you may end up linking against the insecure" when trying to link it

So I just linked it by supplying the full path like so

ln -s /usr/local/opt/openssl/bin/openssl /usr/local/bin/openssl

Now it's showing version OpenSSL 1.0.2o when I do "openssl version -a", I'm assuming it worked

For python3, on a Mac you must use pip3 to install selenium.

sudo pip3 install selenium

If the case is:

n=int(input())

Instead of -> for i in n: -> gives error- 'int' object is not iterable

Use -> for i in range(0,n): -> works fine..!

If you response is like {'customer':{'first_name':'John','last_name':'Cena'}}

var d = JSON.parse(response);
alert(d.customer.first_name); // contains "John"

Thanks,

The simplest way is to use,

<iframe src="pdf-link">
</iframe>

and if its still getting downloaded instead of viewing, check the server response header, it should have, Content-Disposition:Inline and not, Content-Disposition:Attachment.

To add to Ivo Wetzel's answer

There seems to be a shorthand syntax for exports ? this that I can only find documented/mentioned on a Google group posting.

I.e. in a web page to make a function available globally you declare the function again with an @ prefix:

<script type="text/coffeescript">
    @aglobalfunction = aglobalfunction = () ->
         alert "Hello!"
</script>

<a href="javascript:aglobalfunction()" >Click me!</a>

SWT by itself is pretty low-level, and it uses the platform's native widgets through JNI. It is not related to Swing and AWT at all. The Eclipse IDE and all Eclipse-based Rich Client Applications, like the Vuze BitTorrent client, are built using SWT. Also, if you are developing Eclipse plugins, you will typically use SWT.
I have been developing Eclipse-based applications and plugins for almost 5 years now, so I'm clearly biased. However, I also have extensive experience in working with SWT and the JFace UI toolkit, which is built on top of it. I have found JFace to be very rich and powerful; in some cases it might even be the main reason for choosing SWT. It enables you to whip up a working UI quite quickly, as long as it is IDE-like (with tables, trees, native controls, etc). Of course you can integrate your custom controls as well, but that takes some extra effort.

In Visual Studio you can use nuget to download the latest version. Just right click on the project and click 'Manage NuGet Packages' then search online for MySql.Data and install.

String.Format adds many options in addition to the concatenation operators, including the ability to specify the specific format of each item added into the string.

For details on what is possible, I'd recommend reading the section on MSDN titled Composite Formatting. It explains the advantage of String.Format (as well as xxx.WriteLine and other methods that support composite formatting) over normal concatenation operators.

I use it like

<tbody>
  { numrows ? (
     numrows.map(obj => { return <ObjectRow /> }) 
    ) : null
  }
</tbody>

Proximity Sensor Dial

*#*#7378423#*#*

1) Service Tests - (If present)

2) Proximity Switch

3) Test on sensor (Next to logo(top) of mobile)

4) Yes if works, then u can keep on and proximity switch forever which gives beep all the time and consumes lot of battery

OR

4) No it doesn't work - Then simply clean the mobile screen or screen guard and clear the blocked screen from sensor. It works charm.

Technically, Its not any software solution, but hardware solution will work.

If you don't mind picking the same item again at some other time:

$items[rand(0, count($items) - 1)];

Brian's answer (a custom function) is the correct and simplest thing to do in general.

But if you really wanted to define a numeric type with a (non-standard) '%' operator, like desk calculators do, so that 'X % Y' means X * Y / 100.0, then from Python 2.6 onwards you can redefine the mod() operator:

import numbers

class MyNumberClasswithPct(numbers.Real):
    def __mod__(self,other):
        """Override the builtin % to give X * Y / 100.0 """
        return (self * other)/ 100.0
    # Gotta define the other 21 numeric methods...
    def __mul__(self,other):
        return self * other # ... which should invoke other.__rmul__(self)
    #...

This could be dangerous if you ever use the '%' operator across a mixture of MyNumberClasswithPct with ordinary integers or floats.

What's also tedious about this code is you also have to define all the 21 other methods of an Integral or Real, to avoid the following annoying and obscure TypeError when you instantiate it

("Can't instantiate abstract class MyNumberClasswithPct with abstract methods __abs__,  __add__, __div__, __eq__, __float__, __floordiv__, __le__, __lt__, __mul__,  __neg__, __pos__, __pow__, __radd__, __rdiv__, __rfloordiv__, __rmod__, __rmul__,  __rpow__, __rtruediv__, __truediv__, __trunc__")

If like me you need to do this all the time, you can set up an alias to do it automatically by adding the following to your .gitconfig file:

[alias]
    set-upstream = !git branch --set-upstream-to=origin/`git symbolic-ref --short HEAD`

When you see the message There is no tracking information..., just run git set-upstream, then git push again.

Thanks to https://zarino.co.uk/post/git-set-upstream/

You can also use INT_MAX:

http://www.cplusplus.com/reference/climits/

it's equivalent to using numeric_limits.

I had the same problem on a Windows 7 and Eclipse 3.7 I managed to fix it by starting

eclipse.exe -vm "D:\JDK6\bin"

You can start a cmd and launch eclipse like that, or you can edit your shortcut and add -vm "D:\JDK6\bin" as an argument in the "target section".

As a sidenote, I also tried to add -vm "D:\JDK6\bin" to eclipse.ini but did not work. And adding JRE6 will not work since it does NOT contain tools.jar in it's "lib" directory. Only JDK does.

This is not another code as you have already helped yourself; but for you to take a look at the performance when using Excel functions in VBA.

• Match() is faster for smaller number of search, but it isn't when it compared to a large number of data. And in that instance you may consider a variant array/dictionary/arrayList approach depending on if you want to sort, you want to have duplicates or not..

• Error handling on Match

PS: **On a latter note, if you wish to do pattern matching then you may consider ScriptingObject **Regex.

The documentation for this at the MySQL site is woefully out of date and riddled with foot-guns (such as interactive_timeout). Issuing FLUSH TABLES WITH READ LOCK as part of your export of the master generally only makes sense when coordinated with a storage/filesystem snapshot such as LVM or zfs.

If you are going to use mysqldump, you should rely instead on the --master-data option to guard against human error and release the locks on the master as quickly as possible.

Assume the master is 192.168.100.50 and the slave is 192.168.100.51, each server has a distinct server-id configured, the master has binary logging on and the slave has read-only=1 in my.cnf

To stage the slave to be able to start replication just after importing the dump, issue a CHANGE MASTER command but omit the log file name and position:

slaveserver> CHANGE MASTER TO MASTER_HOST='192.168.100.50', MASTER_USER='replica', MASTER_PASSWORD='asdmk3qwdq1';

Issue the GRANT on the master for the slave to use:

masterserver> GRANT REPLICATION SLAVE ON *.* TO 'replica'@'192.168.100.51' IDENTIFIED BY 'asdmk3qwdq1';

Export the master (in screen) using compression and automatically capturing the correct binary log coordinates:

mysqldump --master-data --all-databases --flush-privileges | gzip -1 > replication.sql.gz

Copy the replication.sql.gz file to the slave and then import it with zcat to the instance of MySQL running on the slave:

zcat replication.sql.gz | mysql

Start replication by issuing the command to the slave:

slaveserver> START SLAVE;

Optionally update the /root/.my.cnf on the slave to store the same root password as the master.

If you are on 5.1+, it is best to first set the master's binlog_format to MIXED or ROW. Beware that row logged events are slow for tables which lack a primary key. This is usually better than the alternative (and default) configuration of binlog_format=statement (on master), since it is less likely to produce the wrong data on the slave.

If you must (but probably shouldn't) filter replication, do so with slave options replicate-wild-do-table=dbname.% or replicate-wild-ignore-table=badDB.% and use only binlog_format=row

This process will hold a global lock on the master for the duration of the mysqldump command but will not otherwise impact the master.

If you are tempted to use mysqldump --master-data --all-databases --single-transaction (because you only using InnoDB tables), you are perhaps better served using MySQL Enterprise Backup or the open source implementation called xtrabackup (courtesy of Percona)

If you are looking for a programmatical modal creation, you might love this:

http://nakupanda.github.io/bootstrap3-dialog/

Even though Bootstrap's modal provides a javascript way for modal creation, you still need to write modal's html markups first.

You can either use JavaScript or CSS3.

JavaScript solution: Use an absolute positioned <img> tag and resize it on the page load and whenever the page resizes. Be careful of possible bugs when trying to get the page/window size.

CSS3 solution: Use the CSS3 background-size property. You might use either 100% 100% or contain or cover, depending on how you want the image to resize. Of course, this only works on modern browsers.

Try this

#/bin/bash

read -p "Enter a word: " word
echo "You entered $word"

I found great tutorial on the web about some workaround. It is simple and efficient, I used it in several projects with REST urls styles approach:

http://www.kuligowski.pl/java/rest-style-urls-and-url-mapping-for-static-content-apache-tomcat,5

In general,

variable=$(command)

or

variable=`command`

The latter one is the old syntax, prefer $(command).

Note: variable = .... means execute the command variable with the first argument =, the second ....
