If you need binary mode, you'll need to do it the hard way:

s = File.open(filename, 'rb') { |f| f.read }

If not, shorter and sweeter is:

s = IO.read(filename)

date -j -f "%Y-%m-%d" "2010-10-02" "+%s"

INSERT INTO exampleTbl VALUES('he doesn''t work for me')

If you're adding a record through ASP.NET, you can use the SqlParameter object to pass in values so you don't have to worry about the apostrophe's that users enter in.

Any time you do a remove() or a removeAll(), you should call

  validate();
  repaint();

after you have completed add()'ing the new components.

Calling validate() or revalidate() is mandatory when you do a remove() - see the relevant javadocs.

My own testing indicates that repaint() is also necessary. I'm not sure exactly why.

Considering Ionic's ability to cache view elements and scope data mentioned above, this might be another way of doing, if you want to run the controller every time the view gets loaded. You can globally disable the caching mechanism used by ionic by doing:

$ionicConfigProvider.views.maxCache(0);

Else, the way I had it working for me was doing

$scope.$on("$ionicView.afterLeave", function () {
     $ionicHistory.clearCache();
}); 

This is to clear the cache before leaving the view to re-run controller every time you enter back again.

Yet another take at this is to forgo all the character mapping altogether and to instead convert all unwanted characters into their respective numeric character references, e.g.:

function escapeHtml(raw) {
    return raw.replace(/[&<>"']/g, function onReplace(match) {
        return '&#' + match.charCodeAt(0) + ';';
    });
}

Note that the specified RegEx only handles the specific characters that the OP wanted to escape but, depending on the context that the escaped HTML is going to be used, these characters may not be sufficient. Ryan Grove’s article There's more to HTML escaping than &, <, >, and " is a good read on the topic. And depending on your context, the following RegEx may very well be needed in order to avoid XSS injection:

var regex = /[&<>"'` !@$%()=+{}[\]]/g

To round a double in Dart to a given degree of precision AFTER the decimal point, you can use built-in solution in dart toStringAsFixed() method, but you have to convert it back to double

void main() {
  double step1 = 1/3;  
  print(step1); // 0.3333333333333333
  
  String step2 = step1.toStringAsFixed(2); 
  print(step2); // 0.33 
  
  double step3 = double.parse(step2);
  print(step3); // 0.33
}

Have you tried using ASP.NET MVC TempData ?

ASP.NET MVC TempData dictionary is used to share data between controller actions. The value of TempData persists until it is read or until the current user’s session times out. Persisting data in TempData is useful in scenarios such as redirection, when values are needed beyond a single request.

The code would be something like this:

[HttpPost]
public ActionResult ApplicationPoolsUpdate(ServiceViewModel viewModel)
{
    XDocument updatedResultsDocument = myService.UpdateApplicationPools();
    TempData["doc"] = updatedResultsDocument;
    return RedirectToAction("UpdateConfirmation");
}

And in the ApplicationPoolController:

public ActionResult UpdateConfirmation()
{
    if (TempData["doc"] != null)
    {
        XDocument updatedResultsDocument = (XDocument) TempData["doc"];
            ...
        return View();
    }
}

No not directly. What you can do though is quickly exit insert mode for a single normal mode operation with Ctrl-O and then paste from there which will end by putting you back in insert mode.

Key Combo: Ctrl-O p

EDIT: Interesting. It does appear that there is a way as several other people have listed.

Just go with below points. Open Eclipse Windows -> show View -> server -> double click tomcat/press Fn + F3 -> Timeouts -> increase start time Save setting and Restart eclipse also delete .metadata folder from work space if you don't need Check Now... All The Best

{{ Request()->parameter }}

First off, (though this won't change the performance at all) consider cleaning up your code, similar to this:

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

x = np.arange(0, 2*np.pi, 0.01)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)
styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
lines = [ax.plot(x, y, style)[0] for ax, style in zip(axes, styles)]

fig.show()

tstart = time.time()
for i in xrange(1, 20):
    for j, line in enumerate(lines, start=1):
        line.set_ydata(np.sin(j*x + i/10.0))
    fig.canvas.draw()

print 'FPS:' , 20/(time.time()-tstart)

With the above example, I get around 10fps.

Just a quick note, depending on your exact use case, matplotlib may not be a great choice. It's oriented towards publication-quality figures, not real-time display.

However, there are a lot of things you can do to speed this example up.

There are two main reasons why this is as slow as it is.

1) Calling fig.canvas.draw() redraws everything. It's your bottleneck. In your case, you don't need to re-draw things like the axes boundaries, tick labels, etc.

2) In your case, there are a lot of subplots with a lot of tick labels. These take a long time to draw.

Both these can be fixed by using blitting.

To do blitting efficiently, you'll have to use backend-specific code. In practice, if you're really worried about smooth animations, you're usually embedding matplotlib plots in some sort of gui toolkit, anyway, so this isn't much of an issue.

However, without knowing a bit more about what you're doing, I can't help you there.

Nonetheless, there is a gui-neutral way of doing it that is still reasonably fast.

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

x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)

fig.show()

# We need to draw the canvas before we start animating...
fig.canvas.draw()

styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
    return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]

# Let's capture the background of the figure
backgrounds = [fig.canvas.copy_from_bbox(ax.bbox) for ax in axes]

tstart = time.time()
for i in xrange(1, 2000):
    items = enumerate(zip(lines, axes, backgrounds), start=1)
    for j, (line, ax, background) in items:
        fig.canvas.restore_region(background)
        line.set_ydata(np.sin(j*x + i/10.0))
        ax.draw_artist(line)
        fig.canvas.blit(ax.bbox)

print 'FPS:' , 2000/(time.time()-tstart)

This gives me ~200fps.

To make this a bit more convenient, there's an animations module in recent versions of matplotlib.

As an example:

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

x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)

styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
    return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]

def animate(i):
    for j, line in enumerate(lines, start=1):
        line.set_ydata(np.sin(j*x + i/10.0))
    return lines

# We'd normally specify a reasonable "interval" here...
ani = animation.FuncAnimation(fig, animate, xrange(1, 200), 
                              interval=0, blit=True)
plt.show()

Search: When searching for a specific place, the resulting map puts a pin in the specified location and displays available place details.

Important: The parameter api=1 identifies the version of Maps URLs this URL is intended for. This parameter is required in every request. The only valid value is 1. If api=1 is NOT present in the URL, all parameters are ignored and the default Google Maps app will launch, either in a browser or the Google Maps mobile app, depending on the platform in use (for example, https://www.google.com/maps).

I've found that the best (and easiest) way to delete leading, trailing (and excessive) spaces in Excel is to use a third-party plugin. I've been using ASAP Utilities for Excel and it accomplishes the task as well as adds many other much-needed features. This approach doesn't require writing formulas and can remove spaces on any selection spanning multiple columns and/or rows. I also use this to sanitize and remove the uninvited non-breaking space that often finds its way into Excel data when copying-and-pasting from other Microsoft products.

More information regarding ASAP Utilities and trimming can be found here:

Old question but I had similar issue and I solved it by adding

extern void* memset(void*, int, size_t);

or just

extern void* memset();

at the top of translation unit ( *.c file ).

If the property name is different from what you want to call it (i.e. language differences) you can do like this:

MyType.cs

using System;
using System.Runtime.Serialization;
using Newtonsoft.Json;
using Newtonsoft.Json.Converters;

[JsonConverter(typeof(StringEnumConverter))]
public enum MyType
{
    [EnumMember(Value = "person")]
    Person,
    [EnumMember(Value = "annan_deltagare")]
    OtherPerson,
    [EnumMember(Value = "regel")]
    Rule,
}

EnumExtensions.cs

using System;
using Newtonsoft.Json;
using Newtonsoft.Json.Converters;

public static class EnumExtensions
{
    public static TEnum ToEnum<TEnum>(this string value) where TEnum : Enum
    {
        var jsonString = $"'{value.ToLower()}'";
        return JsonConvert.DeserializeObject<TEnum>(jsonString, new StringEnumConverter());
    }

    public static bool EqualsTo<TEnum>(this string strA, TEnum enumB) where TEnum : Enum
    {
        TEnum enumA;
        try
        {
            enumA = strA.ToEnum<TEnum>();
        }
        catch
        {
            return false;
        }
        return enumA.Equals(enumB);
    }
}

Program.cs

public class Program
{
    static public void Main(String[] args) 
    { 
        var myString = "annan_deltagare";
        var myType = myString.ToEnum<MyType>();
        var isEqual = myString.EqualsTo(MyType.OtherPerson);
        //Output: true
    }     
}

So many ways to do this... for #NetCore use Lib..

git checkout old_branch
git branch new_branch

This will give you a new branch "new_branch" with the same state as "old_branch".

This command can be combined to the following:

git checkout -b new_branch old_branch

I know there isn't any need to add a plugin for this.

But this can be useful if you are doing so many things with numbers. So checkout this plugin at least for a knowledge point of view.

The rest of karim79's answer is super cool.

my solution is similar to the solution given by Server Themes. Do check it once:

localStorage.setItem("validNavigation", false);
$(document).on('keypress', function (e) {
    if (e.keyCode == 116) {
        localStorage.setItem("validNavigation", true);
    }
});

// Attach the event click for all links in the page
$(document).on("click", "a", function () {
    localStorage.setItem("validNavigation", true);
});

// Attach the event submit for all forms in the page
$(document).on("submit", "form", function () {
    localStorage.setItem("validNavigation", true);
});

// Attach the event click for all inputs in the page
$(document).bind("click", "input[type=submit]", function () {
    localStorage.setItem("validNavigation", true);
});

$(document).bind("click", "button[type=submit]", function () {
    localStorage.setItem("validNavigation", true);
});
window.onbeforeunload = function (event) {

    if (localStorage.getItem("validNavigation") === "false") {
        event.returnValue = "Write something clever here..";
        console.log("Test success!");
        localStorage.setItem("validNavigation", false);
    }
};

If you put the breakpoints correctly on the browser page, the if condition will be true only when the browser is about to be closed or the tab is about to be closed.

You have two ways to do that, both use the Arrays utility class

1. Implement a Comparator and pass your array along with the comparator to the sort method which take it as second parameter.
2. Implement the Comparable interface in the class your objects are from and pass your array to the sort method which takes only one parameter.

Example

class Book implements Comparable<Book> {
    public String name, id, author, publisher;
    public Book(String name, String id, String author, String publisher) {
        this.name = name;
        this.id = id;
        this.author = author;
        this.publisher = publisher;
    }
    public String toString() {
        return ("(" + name + ", " + id + ", " + author + ", " + publisher + ")");
    }
    @Override
    public int compareTo(Book o) {
        // usually toString should not be used,
        // instead one of the attributes or more in a comparator chain
        return toString().compareTo(o.toString());
    }
}

@Test
public void sortBooks() {
    Book[] books = {
            new Book("foo", "1", "author1", "pub1"),
            new Book("bar", "2", "author2", "pub2")
    };

    // 1. sort using Comparable
    Arrays.sort(books);
    System.out.println(Arrays.asList(books));

    // 2. sort using comparator: sort by id
    Arrays.sort(books, new Comparator<Book>() {
        @Override
        public int compare(Book o1, Book o2) {
            return o1.id.compareTo(o2.id);
        }
    });
    System.out.println(Arrays.asList(books));
}

Output

[(bar, 2, author2, pub2), (foo, 1, author1, pub1)]
[(foo, 1, author1, pub1), (bar, 2, author2, pub2)]

My preference is to encode all non-alphaumeric characters as HTML numeric character entities. Since almost, if not all attacks require non-alphuneric characters (like <, ", etc) this should eliminate a large chunk of dangerous output.

Format is &#N;, where N is the numeric value of the character (you can just cast the character to an int and concatenate with a string to get a decimal value). For example:

// java-ish pseudocode
StringBuffer safestrbuf = new StringBuffer(string.length()*4);
foreach(char c : string.split() ){  
  if( Character.isAlphaNumeric(c) ) safestrbuf.append(c);
  else safestrbuf.append(""+(int)symbol);

You will also need to be sure that you are encoding immediately before outputting to the browser, to avoid double-encoding, or encoding for HTML but sending to a different location.

French translations:

$('#my_table').DataTable({
  "language": {
    "sProcessing": "Traitement en cours ...",
    "sLengthMenu": "Afficher _MENU_ lignes",
    "sZeroRecords": "Aucun résultat trouvé",
    "sEmptyTable": "Aucune donnée disponible",
    "sInfo": "Lignes _START_ à _END_ sur _TOTAL_",
    "sInfoEmpty": "Aucune ligne affichée",
    "sInfoFiltered": "(Filtrer un maximum de_MAX_)",

    },
    "oAria": {

    }
  }
});

});

Try:

psql -U user_name  -h 127.0.0.1 -d db_name

where

• -U is the database user name
• -h is the hostname/IP of the local server, thus avoiding Unix domain sockets
• -d is the database name to connect to

This is then evaluated as a "network" connection by Postgresql rather than a Unix domain socket connection, thus not evaluated as a "local" connect as you might see in pg_hba.conf:

local   all             all                                     peer

In your layout XML:

<TextView
        android:id="@+id/myAwesomeTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="Escriba el mensaje y luego clickee el canal a ser enviado"
        android:textSize="20sp" />

Then, in your activity class:

// globally 
TextView myAwesomeTextView = (TextView)findViewById(R.id.myAwesomeTextView);

//in your OnCreate() method
myAwesomeTextView.setText("My Awesome Text");

#access a {
    border-bottom: 2px solid #fff;
    color: #eee;
    display: block;
    line-height: 3.333em;
    padding: 0 10px 0 20px;
    text-decoration: none;
}

I see that you had used line-height but you gave it to <a> tag instead of <ul> Try this:

#access ul {line-height:3.333em;}

You wouldn't need to play with margins then.

<?php
$time    = '21:32:32';
$seconds = 0;
$parts   = explode(':', $time);

if (count($parts) > 2) {
    $seconds += $parts[0] * 3600;
}
$seconds += $parts[1] * 60;
$seconds += $parts[2];

Lets assume this code is running in a thread:

private static ReentrantLock lock = new ReentrantLock();

void accessResource() {
    lock.lock();
    if( checkSomeCondition() ) {
        accessResource();
    }
    lock.unlock();
}

Because the thread owns the lock it will allow multiple calls to lock(), so it re-enter the lock. This can be achieved with a reference count so it doesn't has to acquire lock again.

Beginning PowerShell 5.0 New-Item, Remove-Item, and Get-ChildItem have been enhanced to support creating and managing symbolic links. The ItemType parameter for New-Item accepts a new value, SymbolicLink. Now you can create symbolic links in a single line by running the New-Item cmdlet.

New-Item -ItemType SymbolicLink -Path "C:\temp" -Name "calc.lnk" -Value "c:\windows\system32\calc.exe"

Be Carefull a SymbolicLink is different from a Shortcut, shortcuts are just a file. They have a size (A small one, that just references where they point) and they require an application to support that filetype in order to be used. A symbolic link is filesystem level, and everything sees it as the original file. An application needs no special support to use a symbolic link.

Anyway if you want to create a Run As Administrator shortcut using Powershell you can use

$file="c:\temp\calc.lnk"
$bytes = [System.IO.File]::ReadAllBytes($file)
$bytes[0x15] = $bytes[0x15] -bor 0x20 #set byte 21 (0x15) bit 6 (0x20) ON (Use –bor to set RunAsAdministrator option and –bxor to unset)
[System.IO.File]::WriteAllBytes($file, $bytes)

If anybody want to change something else in a .LNK file you can refer to official Microsoft documentation.

(I would have posted this as a comment, but couldn't)

For anyone who lands here trying to update one field using another in the document with the c# driver... I could not figure out how to use any of the UpdateXXX methods and their associated overloads since they take an UpdateDefinition as an argument.

// we want to set Prop1 to Prop2
class Foo { public string Prop1 { get; set; } public string Prop2 { get; set;} } 

void Test()
{ 
     var update = new UpdateDefinitionBuilder<Foo>();
     update.Set(x => x.Prop1, <new value; no way to get a hold of the object that I can find>)
}

As a workaround, I found that you can use the RunCommand method on an IMongoDatabase (https://docs.mongodb.com/manual/reference/command/update/#dbcmd.update).

var command = new BsonDocument
        {
            { "update", "CollectionToUpdate" },
            { "updates", new BsonArray 
                 { 
                       new BsonDocument
                       {
                            // Any filter; here the check is if Prop1 does not exist
                            { "q", new BsonDocument{ ["Prop1"] = new BsonDocument("$exists", false) }}, 
                            // set it to the value of Prop2
                            { "u", new BsonArray { new BsonDocument { ["$set"] = new BsonDocument("Prop1", "$Prop2") }}},
                            { "multi", true }
                       }
                 }
            }
        };

 database.RunCommand<BsonDocument>(command);

The Best way is to create a user for your application and assign the permissions that are suitable for that user. Dont use 'NT AUTHORITY\NETWORK SERVICE' as your user it has its own vulnerability and it is a user that has permissions to so many things on the OS level. Stay away from this built in user.

Solving this will require a platform specific solution. Look for opendir() on unix/linux or FindFirstFile() on Windows. Or, there are many libraries that will handle the platform specific part for you.

Using open, read, write means you have to worry about signal interaptions.

If the call was interrupted by a signal handler the functions will return -1 and set errno to EINTR.

So the proper way to close a file would be

while (retval = close(fd), retval == -1 && ernno == EINTR) ;

I had a similar problem, there isn't a service.bat in the zip version of tomcat that I downloaded ages ago.

I simply downloaded a new 64-bit Windows zip version of tomcat from http://tomcat.apache.org/download-70.cgi and replaced my existing tomcat\bin folder with the one I just downloaded (Remember to keep a backup first!).

Start command prompt > navigate to the tomcat\bin directory > issue the command:

service.bat install

Hope that helps!

jagpdf seems to be one of them. It is written in C++ but provides a C API.

You must specify which type the response is

  this.productService.getProducts().subscribe(res => {
          this.productsArray = res;
        });

Try this

  this.productService.getProducts().subscribe((res: Product[]) => {
          this.productsArray = res;
        });

First create an xpath selector function.

function _x(STR_XPATH) {
    var xresult = document.evaluate(STR_XPATH, document, null, XPathResult.ANY_TYPE, null);
    var xnodes = [];
    var xres;
    while (xres = xresult.iterateNext()) {
        xnodes.push(xres);
    }

    return xnodes;
}

To use the xpath selector with jquery, you can do like this:

$(_x('/html/.//div[@id="text"]')).attr('id', 'modified-text');

Hope this can help.

As has been mentioned by others, std::unique_lock tracks the locked status of the mutex, so you can defer locking until after construction of the lock, and unlock before destruction of the lock. std::lock_guard does not permit this.

There seems no reason why the std::condition_variable wait functions should not take a lock_guard as well as a unique_lock, because whenever a wait ends (for whatever reason) the mutex is automatically reacquired so that would not cause any semantic violation. However according to the standard, to use a std::lock_guard with a condition variable you have to use a std::condition_variable_any instead of std::condition_variable.

Edit: deleted "Using the pthreads interface std::condition_variable and std::condition_variable_any should be identical". On looking at gcc's implementation:

• std::condition_variable::wait(std::unique_lock&) just calls pthread_cond_wait() on the underlying pthread condition variable with respect to the mutex held by unique_lock (and so could equally do the same for lock_guard, but doesn't because the standard doesn't provide for that)
• std::condition_variable_any can work with any lockable object, including one which is not a mutex lock at all (it could therefore even work with an inter-process semaphore)

Use this code where str is your JSON string:

NSError *err = nil;
NSArray *arr = 
 [NSJSONSerialization JSONObjectWithData:[str dataUsingEncoding:NSUTF8StringEncoding] 
                                 options:NSJSONReadingMutableContainers 
                                   error:&err];
// access the dictionaries
NSMutableDictionary *dict = arr[0];
for (NSMutableDictionary *dictionary in arr) {
  // do something using dictionary
}

In Oracle (For last 24 hours):

SELECT  *
FROM    my_table
WHERE   date_column >= SYSDATE - 24/24

In case, for any reason, you have rows with future dates, you can use between, like this:

SELECT  *
FROM    my_table
WHERE   date_column BETWEEN (SYSDATE - 24/24) AND SYSDATE

Instead of copy/pasting the code from the tutorial, use the code suggestion in the IDE. Start typing "extends ActionBar..." it will propose "ActionBarActivity" click enter. It worked for me!

I have found that the following implementations are effective:

$('#freeform_first_name').removeAttr('required');

$('#freeform_first_name').attr('required', 'required');

These commands (attr, removeAttr, prop) behave differently depending on the version of JQuery you are using. Please reference the documentation here: https://api.jquery.com/attr/

When you use just "localhost" the MySQL client library tries to use a Unix domain socket for the connection instead of a TCP/IP connection. The error is telling you that the socket, called MySQL, cannot be used to make the connection, probably because it does not exist (error number 2).

From the MySQL Documentation:

On Unix, MySQL programs treat the host name localhost specially, in a way that is likely different from what you expect compared to other network-based programs. For connections to localhost, MySQL programs attempt to connect to the local server by using a Unix socket file. This occurs even if a --port or -P option is given to specify a port number. To ensure that the client makes a TCP/IP connection to the local server, use --host or -h to specify a host name value of 127.0.0.1, or the IP address or name of the local server. You can also specify the connection protocol explicitly, even for localhost, by using the --protocol=TCP option.

There are a few ways to solve this problem.

1. You can just use TCP/IP instead of the Unix socket. You would do this by using 127.0.0.1 instead of localhost when you connect. The Unix socket might by faster and safer to use, though.
2. You can change the socket in php.ini: open the MySQL configuration file my.cnf to find where MySQL creates the socket, and set PHP's mysqli.default_socket to that path. On my system it's /var/run/mysqld/mysqld.sock.

3. Configure the socket directly in the PHP script when opening the connection. For example:

   $db = new MySQLi('localhost', 'kamil', '***', '', 0, 
                                 '/var/run/mysqld/mysqld.sock')
   

When a user connects, it should send a message to the server with a username which has to be unique, like an email.

A pair of username and socket should be stored in an object like this:

var users = {
    '[email protected]': [socket object],
    '[email protected]': [socket object],
    '[email protected]': [socket object]
}

On the client, emit an object to the server with the following data:

{
    to:[the other receiver's username as a string],
    from:[the person who sent the message as string],
    message:[the message to be sent as string]
}

On the server, listen for messages. When a message is received, emit the data to the receiver.

users[data.to].emit('receivedMessage', data)

On the client, listen for emits from the server called 'receivedMessage', and by reading the data you can handle who it came from and the message that was sent.

The difference is that std::make_shared performs one heap-allocation, whereas calling the std::shared_ptr constructor performs two.

Where do the heap-allocations happen?

std::shared_ptr manages two entities:

• the control block (stores meta data such as ref-counts, type-erased deleter, etc)
• the object being managed

std::make_shared performs a single heap-allocation accounting for the space necessary for both the control block and the data. In the other case, new Obj("foo") invokes a heap-allocation for the managed data and the std::shared_ptr constructor performs another one for the control block.

For further information, check out the implementation notes at cppreference.

Update I: Exception-Safety

NOTE (2019/08/30): This is not a problem since C++17, due to the changes in the evaluation order of function arguments. Specifically, each argument to a function is required to fully execute before evaluation of other arguments.

Since the OP seem to be wondering about the exception-safety side of things, I've updated my answer.

Consider this example,

void F(const std::shared_ptr<Lhs> &lhs, const std::shared_ptr<Rhs> &rhs) { /* ... */ }

F(std::shared_ptr<Lhs>(new Lhs("foo")),
  std::shared_ptr<Rhs>(new Rhs("bar")));

Because C++ allows arbitrary order of evaluation of subexpressions, one possible ordering is:

1. new Lhs("foo"))
2. new Rhs("bar"))
3. std::shared_ptr<Lhs>
4. std::shared_ptr<Rhs>

Now, suppose we get an exception thrown at step 2 (e.g., out of memory exception, Rhs constructor threw some exception). We then lose memory allocated at step 1, since nothing will have had a chance to clean it up. The core of the problem here is that the raw pointer didn't get passed to the std::shared_ptr constructor immediately.

One way to fix this is to do them on separate lines so that this arbitary ordering cannot occur.

auto lhs = std::shared_ptr<Lhs>(new Lhs("foo"));
auto rhs = std::shared_ptr<Rhs>(new Rhs("bar"));
F(lhs, rhs);

The preferred way to solve this of course is to use std::make_shared instead.

F(std::make_shared<Lhs>("foo"), std::make_shared<Rhs>("bar"));

Update II: Disadvantage of std::make_shared

Quoting Casey's comments:

Since there there's only one allocation, the pointee's memory cannot be deallocated until the control block is no longer in use. A weak_ptr can keep the control block alive indefinitely.

Why do instances of weak_ptrs keep the control block alive?

There must be a way for weak_ptrs to determine if the managed object is still valid (eg. for lock). They do this by checking the number of shared_ptrs that own the managed object, which is stored in the control block. The result is that the control blocks are alive until the shared_ptr count and the weak_ptr count both hit 0.

Back to std::make_shared

Since std::make_shared makes a single heap-allocation for both the control block and the managed object, there is no way to free the memory for control block and the managed object independently. We must wait until we can free both the control block and the managed object, which happens to be until there are no shared_ptrs or weak_ptrs alive.

Suppose we instead performed two heap-allocations for the control block and the managed object via new and shared_ptr constructor. Then we free the memory for the managed object (maybe earlier) when there are no shared_ptrs alive, and free the memory for the control block (maybe later) when there are no weak_ptrs alive.

If the error happens with error column "File" as SGEN, then the fix needs to be in a file sgen.exe.config, next to sgen.exe. For example, for VS 2015, create C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6 Tools\sgen.exe.config. Minimum file contents: <configuration><startup useLegacyV2RuntimeActivationPolicy="true"/></configuration>

Sample to execute an SQL string within the stored procedure:

(I'm using this to compare the number of entries on each table as first check for a regression test, within a cursor loop)

select @SqlQuery1 = N'select @CountResult1 = (select isnull(count(*),0) from ' + @DatabaseFirst+'.dbo.'+@ObjectName + ')'

execute sp_executesql    @SqlQuery1 , N'@CountResult1 int OUTPUT',     @CountResult1 = @CountResult1 output;

Use this JsonKnownTypes, it's very similar way to use, it just add discriminator to json:

[JsonConverter(typeof(JsonKnownTypeConverter<BaseClass>))]
[JsonKnownType(typeof(Base), "base")]
[JsonKnownType(typeof(Derived), "derived")]
public class Base
{
    public string Name;
}
public class Derived : Base
{
    public string Something;
}

Now when you serialize object in json will be add "$type" with "base" and "derived" value and it will be use for deserialize

Serialized list example:

[
    {"Name":"some name", "$type":"base"},
    {"Name":"some name", "Something":"something", "$type":"derived"}
]

There is a tutorial for creating an HTML5 progress bar here. If you don't want to use HTML5 methods or you are looking for an all-browser solution, try this code:

<div style="width: 150px; height: 25px; background-color: #dbdbdb;">
  <div style="height: 25px; width:87%; background-color: gold">&nbsp;</div>
</div>

You can change the color GOLD to any progress bar color and #dbdbdb to the background-color of your progress bar.

DateFormat df = new SimpleDateFormat("dd/MM/yyyy");
Date fecha = getDateInTimestamp(); 

Try the following:

foo(*values)

This can be found in the Python docs as Unpacking Argument Lists.

Use Object.entries() function.

Object.entries(object) return:

[
    [key, value],
    [key, value],
    ...
]

see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/entries

{Object.entries(subjects).map(([key, subject], i) => (
    <li className="travelcompany-input" key={i}>
        <span className="input-label">key: {i} Name: {subject.name}</span>
    </li>
))}

Avoid any? for large arrays.

• any? is O(n)
• empty? is O(1)

any? does not check the length but actually scans the whole array for truthy elements.

static VALUE
rb_ary_any_p(VALUE ary)
{
  long i, len = RARRAY_LEN(ary);
  const VALUE *ptr = RARRAY_CONST_PTR(ary);

  if (!len) return Qfalse;
  if (!rb_block_given_p()) {
    for (i = 0; i < len; ++i) if (RTEST(ptr[i])) return Qtrue;
  }
  else {
    for (i = 0; i < RARRAY_LEN(ary); ++i) {
        if (RTEST(rb_yield(RARRAY_AREF(ary, i)))) return Qtrue;
    }
  }
  return Qfalse;
}

empty? on the other hand checks the length of the array only.

static VALUE
rb_ary_empty_p(VALUE ary)
{
  if (RARRAY_LEN(ary) == 0)
    return Qtrue;
  return Qfalse;
}

The difference is relevant if you have "sparse" arrays that start with lots of nil values, like for example an array that was just created.

I have a similar request from a client who wants to have the header, page numbers, and html footer removed. In this case, the client is presenting an HTML page that can double as a formal certificate. The added URL, page, and, header, are irrelevant and lead to a less-than-pleasing final product. In some ways, it just looks cheap.

Media=Print has not been able to disable these browser defaults. The only workaround is to tell the user to click the "Gear" button and toggle those items on/off. Seriously, I had no idea I could do that for 20 years (and we think the typical user will have a clue to click the toggle button?).

If CSS supports Media=Print, it should support the ability to control the entire end-user print experience. I appreciate that the browsers provide the added fields, but, why not allow CSS to control the overall print experience-if that is what's desired. A 90% solution could be 100% with three more fields! A simple:

#BrowserPrintDefaults{display:none} 

would suffice.

Again, it's not a matter whether or not the end-user wants to print it out or not (maybe your client is very private and doesn't want printed URLs floating around. Or maybe a executive team uses a private collaboration sites?). Glad to defend the end-user, but if somebody is seeking an answer, don't respond saying it's the right of the end-user to show or hide. Sometimes it's the right of the client paying the bills.

Stick with the present tense imperative because

• it's good to have a standard
• it matches tickets in the bug tracker which naturally have the form "implement something", "fix something", or "test something."

The solution from romeo https://stackoverflow.com/a/2799675/661022 is cool, but I noticed that the code needs one more loop. I was working with tableViewController. I edited the script and then I checked. Everything worked perfect.

I recommed to try this:

- (void)findFirstResponder
{
    NSArray *subviews = [self.tableView subviews];
    for (id subv in subviews )
    {
        for (id cell in [subv subviews] ) {
            if ([cell isKindOfClass:[UITableViewCell class]])
            {
                UITableViewCell *aCell = cell;
                NSArray *cellContentViews = [[aCell contentView] subviews];
                for (id textField in cellContentViews)
                {
                    if ([textField isKindOfClass:[UITextField class]])
                    {
                        UITextField *theTextField = textField;
                        if ([theTextField isFirstResponder]) {
                            NSLog(@"current textField: %@", theTextField);
                            NSLog(@"current textFields's superview: %@", [theTextField superview]);
                        }
                    }
                }
            }
        }
    }
}

Actually we can do it. we can set the file value default by using webbrowser control in c# using FormToMultipartPostData Library.We have to download and include this Library in our project. Webbrowser enables the user to navigate Web pages inside form. Once the web page loaded , the script inside the webBrowser1_DocumentCompleted will be executed. So,

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
       FormToMultipartPostData postData = 
            new FormToMultipartPostData(webBrowser1, form);
        postData.SetFile("fileField", @"C:\windows\win.ini");
        postData.Submit();
    }

Refer the below link for downloading and complete reference.

I've put up some algorithms to do image interpolation on html canvas pixel arrays that might be useful here:

https://web.archive.org/web/20170104190425/http://jsperf.com:80/pixel-interpolation/2

These can be copy/pasted and can be used inside of web workers to resize images (or any other operation that requires interpolation - I'm using them to defish images at the moment).

I haven't added the lanczos stuff above, so feel free to add that as a comparison if you'd like.

An another way is simply :

if($test){
    echo "Yes 1";
}
if(!is_null($test)){
    echo "Yes 2";
}

$test = "hello";

if($test){
    echo "Yes 3";
}

Will return :

"Yes 3"

The best way is to use isset(), otherwise you can have an error like "undefined $test".

You can do it like this :

if( isset($test) && ($test!==null) )

You'll not have any error because the first condition isn't accepted.

Do this:

function changeHeight() {
document.getElementById('chartdiv').style.height = "200px"
}
<button type="button" onClick="changeHeight();"> Click Me!</button>

I typically see performance increases when filtering on the join. Especially if you can join on indexed columns for both tables. You should be able to cut down on logical reads with most queries doing this too, which is, in a high volume environment, a much better performance indicator than execution time.

I'm always mildly amused when someone shows their SQL benchmarking and they've executed both versions of a sproc 50,000 times at midnight on the dev server and compare the average times.

I could not make @Clockwork-Muse work actually. But I could make this variation work:

WITH Tmp AS (SELECT * FROM (VALUES (id1, newsPosX1, newPosY1), 
                                   (id2, newsPosX2, newPosY2),
                                   ......................... ,
                                   (idN, newsPosXN, newPosYN)) d(id, px, py))

UPDATE t

SET posX = (SELECT px FROM Tmp WHERE t.id = Tmp.id),
    posY = (SELECT py FROM Tmp WHERE t.id = Tmp.id)

FROM TableToUpdate t

I hope this works for you too!

If you are using Maven you may have both src/{main,test}/resources/META-INF/persistence.xml. This is a common setup: test your JPA code with h2 or Derby and deploy it with PostgreSQL or some other full DBMS. If you're using this pattern, do make sure the two files have different unit names, else some versions of the Persistence class will try to load BOTH (because of course your test-time CLASSPATH includes both classes and test-classes); this will cause conflicting definitions of the persistence unit, resulting in the dreaded annoying message that we all hate so much!

Worse: this may "work" with some older versions of e.g., Hibernate, but fail with current versions. Worth getting it right anyway...

OK, figured it out now - thanks to Jobi whose answer was close, but not quite.

From a WPF application, here's my code that works:

First a helper class:

private class OldWindow : System.Windows.Forms.IWin32Window
{    
    IntPtr _handle;    
    public OldWindow(IntPtr handle)
    {
        _handle = handle;
    }   

    #region IWin32Window Members    
    IntPtr System.Windows.Forms.IWin32Window.Handle
    {
        get { return _handle; }
    }    
    #endregion
}

Then, to use this:

    System.Windows.Forms.FolderBrowserDialog dlg = new FolderBrowserDialog();
    HwndSource source = PresentationSource.FromVisual(this) as HwndSource;
    System.Windows.Forms.IWin32Window win = new OldWindow(source.Handle);
    System.Windows.Forms.DialogResult result = dlg.ShowDialog(win);

I'm sure I can wrap this up better, but basically it works. Yay! :-)

For example,

package main

import "fmt"

func main() {
    type Map1 map[string]interface{}
    type Map2 map[string]int
    m := Map1{"foo": Map2{"first": 1}, "boo": Map2{"second": 2}}
    //m = map[foo:map[first: 1] boo: map[second: 2]]
    fmt.Println("m:", m)
    for k, v := range m {
        fmt.Println("k:", k, "v:", v)
    }
}

Output:

m: map[boo:map[second:2] foo:map[first:1]]
k: boo v: map[second:2]
k: foo v: map[first:1]

I just hit a problem with this. Mine was a fall off from changing the input to a button and I'd had a badly written /> tag terminator:

So I had:

<button name="submit_login" type="submit" class="login" />Login</button>

And have just amended it to:

<button name="submit_login" type="submit" class="login">Login</button>

Now works like a charm, always the annoying small things... HTH

make sure you have closed all your statments and resultsets before running rs.next. Finaly guarantees this

public boolean flowExists( Integer idStatusPrevious, Integer idStatus, Connection connection ) {
    LogUtil.logRequestMethod();

    PreparedStatement ps = null;
    ResultSet rs = null;
    try {
        ps = connection.prepareStatement( Constants.SCRIPT_SELECT_FIND_FLOW_STATUS_BY_STATUS );
        ps.setInt( 1, idStatusPrevious );
        ps.setInt( 2, idStatus );

        rs = ps.executeQuery();

        Long count = 0L;

        if ( rs != null ) {
            while ( rs.next() ) {
                count = rs.getLong( 1 );
                break;
            }
        }

        LogUtil.logSuccessMethod();

        return count > 0L;
    } catch ( Exception e ) {
        String errorMsg = String
            .format( Constants.ERROR_FINALIZED_METHOD, ( e.getMessage() != null ? e.getMessage() : "" ) );
        LogUtil.logError( errorMsg, e );

        throw new FatalException( errorMsg );
    } finally {
        rs.close();
        ps.close();
    }

To add on to Andreas' answer, you can install only the dependencies by using:

npm install --production

Assuming that you already put your object as attribute on the session map of the current instance of the FacesContext from your managed-bean, you can get it from the JSF page by :

<h:outputText value="#{sessionScope['yourObject'] }" />

If your object has a property, get it by:

<h:ouputText value="#{sessionScope['yourObject'].anyProperty }" />

I think you are asking for something like the code below:

public interface A
{
    void foo() 
        throws AException;
}

public class B
    implements A
{
    @Overrides 
    public void foo()
        throws AException,
               BException
    {
    }
}

This will not work unless BException is a subclass of AException. When you override a method you must conform to the signature that the parent provides, and exceptions are part of the signature.

The solution is to declare the the interface also throws a BException.

The reason for this is you do not want code like:

public class Main
{
    public static void main(final String[] argv)
    {
        A a;

        a = new B();

        try
        {
            a.foo();
        }
        catch(final AException ex)
        {
        }
        // compiler will not let you write a catch BException if the A interface
        // doesn't say that it is thrown.
    }
}

What would happen if B::foo threw a BException? The program would have to exit as there could be no catch for it. To avoid situations like this child classes cannot alter the types of exceptions thrown (except that they can remove exceptions from the list).

If you want to print the text of a UITableViewCell according to its matching NSIndexPath, you have to use UITableViewDelegate's tableView:didSelectRowAtIndexPath: method and get a reference of the selected UITableViewCell with UITableView's cellForRowAtIndexPath: method.

For example:

import UIKit

class TableViewController: UITableViewController {

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 4
    }

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)

        switch indexPath.row {
        case 0: cell.textLabel?.text = "Bike"
        case 1: cell.textLabel?.text = "Car"
        case 2: cell.textLabel?.text = "Ball"
        default: cell.textLabel?.text = "Boat"
        }

        return cell
    }

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        let selectedCell = tableView.cellForRowAtIndexPath(indexPath)
        print(selectedCell?.textLabel?.text)
        // this will print Optional("Bike") if indexPath.row == 0
    }

}

However, for many reasons, I would not encourage you to use the previous code. Your UITableViewCell should only be responsible for displaying some content given by a model. In most cases, what you want is to print the content of your model (could be an Array of String) according to a NSIndexPath. By doing things like this, you will separate each element's responsibilities.

Thereby, this is what I would recommend:

import UIKit

class TableViewController: UITableViewController {

    let toysArray = ["Bike", "Car", "Ball", "Boat"]

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

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
        cell.textLabel?.text = toysArray[indexPath.row]
        return cell
    }

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        let toy = toysArray[indexPath.row]
        print(toy)
        // this will print "Bike" if indexPath.row == 0
    }

}

As you can see, with this code, you don't have to deal with optionals and don't even need to get a reference of the matching UITableViewCell inside tableView:didSelectRowAtIndexPath: in order to print the desired text.

We are looking into adding some kind of formatting to durations in moment.js. See https://github.com/timrwood/moment/issues/463

A couple other libraries that might help out are http://countdownjs.org/ and https://github.com/icambron/twix.js

CASE AlarmEventTransactions.DeviceID should just be CASE.

You are mixing the 2 forms of the CASE expression.

From the documentation of the HttpWebRequest.Timeout property:

A Domain Name System (DNS) query may take up to 15 seconds to return or time out. If your request contains a host name that requires resolution and you set Timeout to a value less than 15 seconds, it may take 15 seconds or more before a WebException is thrown to indicate a timeout on your request.

Is it possible that your DNS query is the cause of the timeout?

You can run the following query to check for the existance of the user table.

SELECT * FROM information_schema.TABLES
WHERE TABLE_NAME LIKE '%user%'

See if you can find a row with the following values in

mysql   user    BASE TABLE  MyISAM  

If you cant find this table look at the following link to rebuild the database How to recover/recreate mysql's default 'mysql' database

320

And the segments look like this

{64}@{255}

64 + 1 + 255 = 320

You should also read this if you are validating emails

You are getting AttributeError because you're calling groups on None, which hasn't any methods.

regex.search returning None means the regex couldn't find anything matching the pattern from supplied string.

when using regex, it is nice to check whether a match has been made:

Result = re.search(SearchStr, htmlString)

if Result:
    print Result.groups()

NB: In these examples, yourObj defines the object you want to examine.

First off my least favorite yet most utilized way of displaying an object:

This is the defacto way of showing the contents of an object

console.log(yourObj)

will produce something like :

I think the best solution is to look through the Objects Keys, and then through the Objects Values if you really want to see what the object holds...

console.log(Object.keys(yourObj));
console.log(Object.values(yourObj));

It will output something like : (pictured above: the keys/values stored in the object)

There is also this new option if you're using ECMAScript 2016 or newer:

Object.keys(yourObj).forEach(e => console.log(`key=${e}  value=${yourObj[e]}`));

This will produce neat output : The solution mentioned in a previous answer: console.log(yourObj) displays too many parameters and is not the most user friendly way to display the data you want. That is why I recommend logging keys and then values separately.

Next up :

console.table(yourObj)

Someone in an earlier comment suggested this one, however it never worked for me. If it does work for someone else on a different browser or something, then kudos! Ill still put the code here for reference! Will output something like this to the console :

you can use the left_on and right_on options as follows:

pd.merge(frame_1, frame_2, left_on='county_ID', right_on='countyid')

I was not sure from the question if you only wanted to merge if the key was in the left hand dataframe. If that is the case then the following will do that (the above will in effect do a many to many merge)

pd.merge(frame_1, frame_2, how='left', left_on='county_ID', right_on='countyid')

I've experienced a problem with length of None, which leads to Internal Server Error: TypeError: object of type 'NoneType' has no len()

My workaround is just displaying 0 if object is None and calculate length of other types, like list in my case:

{{'0' if linked_contacts == None else linked_contacts|length}}

I guess the following code could do the trick:

strs = {'HA' 'KU' 'LA' 'MA' 'TATA'}
ind=find(ismember(strs,'KU'))

This returns

ans = 
     2

Look. This is way old, but on the off chance that someone from Google finds this, absolutely the best solution to this - (and it is AWESOME) - is to use ConEmu (or a package that includes and is built on top of ConEmu called cmder) and then either use plink or putty itself to connect to a specific machine, or, even better, set up a development environment as a local VM using Vagrant.

This is the only way I can ever see myself developing from a Windows box again.

I am confident enough to say that every other answer - while not necessarily bad answers - offer garbage solutions compared to this.

Update: As Of 1/8/2020 not all other solutions are garbage - Windows Terminal is getting there and WSL exists.

I hope this one might help you.

let data = [];
data[0] = { "ID": "1", "Status": "Valid" };
data[1] = { "ID": "2", "Status": "Invalid" };

let tempData = [];

tempData= data.filter((item)=>item.Status!='Invalid')

console.log(tempData)

For anyone using nativescript and facing this issue: you can add

compileSdkVersion 26
buildToolsVersion '26.0.1'

in App_Resources/Android/app.gradle (under android {)

Then run tns platform remove android and tns build android in your project root.

The results of the execution time directly contradict the results of the Query Cost, but I'm having difficulty determining what "Query Cost" actually means.

Query cost is what optimizer thinks of how long your query will take (relative to total batch time).

The optimizer tries to choose the optimal query plan by looking at your query and statistics of your data, trying several execution plans and selecting the least costly of them.

Here you may read in more detail about how does it try to do this.

As you can see, this may differ significantly of what you actually get.

The only real query perfomance metric is, of course, how long does the query actually take.

Beware of using vars as the target directory name for WORKDIR - doing that appears to result in a "cannot normalize nothing" fatal error. IMO, it's also worth pointing out that WORKDIR behaves in the same way as mkdir -p <path> i.e. all elements of the path are created if they don't exist already.

UPDATE: I encountered the variable related problem (mentioned above) whilst running a multi-stage build - it now appears that using a variable is fine - if it (the variable) is "in scope" e.g. in the following, the 2nd WORKDIR reference fails ...

FROM <some image>
ENV varname varval
WORKDIR $varname

FROM <some other image>
WORKDIR $varname

whereas, it succeeds in this ...

FROM <some image>
ENV varname varval
WORKDIR $varname

FROM <some other image>
ENV varname varval
WORKDIR $varname

Edit: Not working anymore with new versions of Gmail

This was the only way I found at the time to get it to work with any characters.

doreamon's answer is the correct way to go now, as it works with all characters in new versions of Gmail.

Old answer:

Here is mine. It seems to works on all Android versions, with subject and message body support, and full utf-8 characters support:

public static void email(Context context, String to, String subject, String body) {
    StringBuilder builder = new StringBuilder("mailto:" + Uri.encode(to));
    if (subject != null) {
        builder.append("?subject=" + Uri.encode(Uri.encode(subject)));
        if (body != null) {
            builder.append("&body=" + Uri.encode(Uri.encode(body)));
        }
    }
    String uri = builder.toString();
    Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.parse(uri));
    context.startActivity(intent);
}

IntelliJ IDEA has a sophisticated merge conflict resolution tool with the Resolve magic wand, which greatly simplifies merging:

If add-apt-repository it's not working try this:

sudo apt-get install python-software-properties

That package is required in order to execute that command, in my server it wasn't installed by default (Ubuntu server x64)

You need to take out the $ signs before the row numbers in the formula....and the row number used in the formula should correspond to the first row of data, so if you are applying this to the ("applies to") range $B$2:$B$5 it must be this formula

=$B2>$C2

by using that "relative" version rather than your "absolute" one Excel (implicitly) adjusts the formula for each row in the range, as if you were copying the formula down

For iOS SWIFT I found this helpful,

let phoneRegEx = "^((\\+)|(00)|(\\*)|())[0-9]{3,14}((\\#)|())$"

There isn't any magic to it. Boolean expressions like a || b || c || d are lazily evaluated. Interpeter looks for the value of a, it's undefined so it's false so it moves on, then it sees b which is null, which still gives false result so it moves on, then it sees c - same story. Finally it sees d and says 'huh, it's not null, so I have my result' and it assigns it to the final variable.

This trick will work in all dynamic languages that do lazy short-circuit evaluation of boolean expressions. In static languages it won't compile (type error). In languages that are eager in evaluating boolean expressions, it'll return logical value (i.e. true in this case).

[Note: edited to modernize ggplot syntax]

Your example is not reproducible since there is no ex1221new (there is an ex1221 in Sleuth2, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot. One advantage is that ggplot works with data.frames directly.

You can set the labels with xlab() and ylab(), or make it part of the scale_*.* call.

library("Sleuth2")
library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  xlab("My x label") +
  ylab("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area("Nitrogen") + 
  scale_x_continuous("My x label") +
  scale_y_continuous("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs function

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  labs(size= "Nitrogen",
       x = "My x label",
       y = "My y label",
       title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

which gives an identical figure to the one above.

FragmentActivity is part of the support library, while Activity is the framework's default class. They are functionally equivalent.

You should always use FragmentActivity and android.support.v4.app.Fragment instead of the platform default Activity and android.app.Fragment classes. Using the platform defaults mean that you are relying on whatever implementation of fragments is used in the device you are running on. These are often multiple years old, and contain bugs that have since been fixed in the support library.

In most browsers, there's a slightly more succinct way of removing an element from the DOM than calling .removeChild(element) on its parent, which is to just call element.remove(). In due course, this will probably become the standard and idiomatic way of removing an element from the DOM.

The .remove() method was added to the DOM Living Standard in 2011 (commit), and has since been implemented by Chrome, Firefox, Safari, Opera, and Edge. It was not supported in any version of Internet Explorer.

If you want to support older browsers, you'll need to shim it. This turns out to be a little irritating, both because nobody seems to have made a all-purpose DOM shim that contains these methods, and because we're not just adding the method to a single prototype; it's a method of ChildNode, which is just an interface defined by the spec and isn't accessible to JavaScript, so we can't add anything to its prototype. So we need to find all the prototypes that inherit from ChildNode and are actually defined in the browser, and add .remove to them.

Here's the shim I came up with, which I've confirmed works in IE 8.

(function () {
    var typesToPatch = ['DocumentType', 'Element', 'CharacterData'],
        remove = function () {
            // The check here seems pointless, since we're not adding this
            // method to the prototypes of any any elements that CAN be the
            // root of the DOM. However, it's required by spec (see point 1 of
            // https://dom.spec.whatwg.org/#dom-childnode-remove) and would
            // theoretically make a difference if somebody .apply()ed this
            // method to the DOM's root node, so let's roll with it.
            if (this.parentNode != null) {
                this.parentNode.removeChild(this);
            }
        };

    for (var i=0; i<typesToPatch.length; i++) {
        var type = typesToPatch[i];
        if (window[type] && !window[type].prototype.remove) {
            window[type].prototype.remove = remove;
        }
    }
})();

This won't work in IE 7 or lower, since extending DOM prototypes isn't possible before IE 8. I figure, though, that on the verge of 2015 most people needn't care about such things.

Once you've included them shim, you'll be able to remove a DOM element element from the DOM by simply calling

element.remove();

Perhaps adobe's flash player detection kit could be helpful here?

You can add a comment to an MSAccess query as follows: Create a dummy field in the query. Not elegant but is self-documentating and contained in the query, which makes cheking it into source code control alot more feasible! Jere's an example. Go into SQL view and add the dummy field (you can do from design view too):

SELECT  "2011-01-21;JTR;Added FIELD02;;2011-01-20;JTR;Added qryHISTORY;;" as qryHISTORY,  ...rest of query here...

Run the query:

qryHISTORY                           FIELD01 FIELD02 ...
2011-01-21;JTR;Added FIELD02;;2011-01-20;JTR;Added qryHISTORY;;"  0000001  ABCDEF ...

Note the use of ";" as field delimiter in qryHISTORY field, and ";;" as an end of comment, and use of ISO date format and intials, as well as comment. Have tested this with up to 646 characters in the qryHISTORY field.

Use an SqlDataAdapter when wanting to populate an in-memory DataSet/DataTable from the database. You then have the flexibility to close/dispose off the connection, pass the datatable/set around in memory. You could then manipulate the data and persist it back into the DB using the data adapter, in conjunction with InsertCommand/UpdateCommand.

Use an SqlDataReader when wanting fast, low-memory footprint data access without the need for flexibility for e.g. passing the data around your business logic. This is more optimal for quick, low-memory usage retrieval of large data volumes as it doesn't load all the data into memory all in one go - with the SqlDataAdapter approach, the DataSet/DataTable would be filled with all the data so if there's a lot of rows & columns, that will require a lot of memory to hold.

I had the same problem and this is my solution. I had the following code:

se.GiftDescription = rs.getString(1);
se.GiftAmount = rs.getInt(2);

And I changed it to:

se.GiftDescription = rs.getString("DESCRIPTION");
se.GiftAmount = rs.getInt("AMOUNT");

And the problem was, after I restarted my PC, the column positions changed. That's why I got this error.

Here's a trick to easily check if the schema already exists, and then create it, in it's own batch, to avoid the error message of trying to create a schema when it's not the only command in a batch.

IF NOT EXISTS (SELECT schema_name 
    FROM information_schema.schemata 
    WHERE schema_name = 'newSchemaName' )
BEGIN
    EXEC sp_executesql N'CREATE SCHEMA NewSchemaName;';
END

You need to use join method of Thread object in the end of the script.

t1 = Thread(target=call_script, args=(scriptA + argumentsA))
t2 = Thread(target=call_script, args=(scriptA + argumentsB))
t3 = Thread(target=call_script, args=(scriptA + argumentsC))

t1.start()
t2.start()
t3.start()

t1.join()
t2.join()
t3.join()

Thus the main thread will wait till t1, t2 and t3 finish execution.

I found a much easier way, it doesn't even use SP.UserProfiles.js. I don't know if it applies to each one's particular case, but definitely worth sharing.

//assume we have a client context called context.
var web = context.get_web();
var user = web.get_currentUser(); //must load this to access info.
context.load(user);
context.executeQueryAsync(function(){
    alert("User is: " + user.get_title()); //there is also id, email, so this is pretty useful.
}, function(){alert(":(");});

Anyways, thanks to your answers, I got to mingle a bit with UserProfiles, even though it is not really necessary for my case.

public class ThreadParameter
        {
            public int Port { get; set; }
            public string Path { get; set; }
        }


Thread t = new Thread(new ParameterizedThreadStart(Startup));
t.Start(new ThreadParameter() { Port = port, Path = path});

Create an object with the port and path objects and pass it to the Startup method.

You should replace WebDriver wb = new FirefoxDriver(); with driver = new FirefoxDriver(); in your @Before Annotation.

As you are accessing driver object with null or you can make wb reference variable as global variable.

You don't have to change anything in the jupyter config code, you just have to make Chrome as your default browser in the setting. Jupyter opens whichever is the default.

Try this first:

git checkout master

(If you're on a different branch than master, use the branch name there instead.)

If that doesn't work, try...

For a single file:

git checkout HEAD /path/to/file

For the entire repository working copy:

git reset --hard HEAD

And if that doesn't work, then you can look in the reflog to find your old head SHA and reset to that:

git reflog
git reset --hard <sha from reflog>

HEAD is a name that always points to the latest commit in your current branch.

A case when process get SIGABRT from itself: Hrvoje mentioned about a buried pure virtual being called from ctor generating an abort, i recreated an example for this. Here when d is to be constructed, it first calls its base class A ctor, and passes inside pointer to itself. the A ctor calls pure virtual method before table was filled with valid pointer, because d is not constructed yet.

#include<iostream>
using namespace std;
class A {
public:
 A(A *pa){pa->f();}
 virtual void f()=0;
};
class D : public A {
public:
 D():A(this){}
 virtual void f() {cout<<"D::f\n";}
};
int main(){
 D d;
 A *pa = &d;
 pa->f();
 return 0;
}

compile: g++ -o aa aa.cpp

ulimit -c unlimited

run: ./aa

pure virtual method called
terminate called without an active exception
Aborted (core dumped)

now lets quickly see the core file, and validate that SIGABRT was indeed called:

gdb aa core

see regs:

i r
rdx            0x6      6
rsi            0x69a    1690
rdi            0x69a    1690
rip            0x7feae3170c37

check code:

disas 0x7feae3170c37

mov    $0xea,%eax  = 234  <- this is the kill syscall, sends signal to process
syscall   <-----

How about if you're copying each column in a sheet to different sheets? Example: row B of mysheet to row B of sheet1, row C of mysheet to row B of sheet 2...

Create your partial view something like:

@model YourModelType
<div>
  <!-- HTML to render your object -->
</div>

Then in your view use:

@Html.Partial("YourPartialViewName", Model)

If you do not want a strongly typed partial view remove the @model YourModelType from the top of the partial view and it will default to a dynamic type.

Update

The default view engine will search for partial views in the same folder as the view calling the partial and then in the ~/Views/Shared folder. If your partial is located in a different folder then you need to use the full path. Note the use of ~/ in the path below.

@Html.Partial("~/Views/Partials/SeachResult.cshtml", Model)

Apparently you can now create folders in S3. I'm not sure since when, but I have a bucket in "Standard" zone and can choose Create Folder from Action dropdown.

Git 101:

git is a decentralized version control system. You do not necessary need a server to get up and running with git. Still you might want to do that as it looks cool, right? (It's also useful if you want to work on a single project from multiple computers.)

So to get a "server" running you need to run git init --bare <your_project>.git as this will create an empty repository, which you can then import on your machines without having to muck around in config files in your .git dir.

After this you could clone the repo on your clients as it is supposed to work, but I found that some clients (namely git-gui) will fail to clone a repo that is completely empty. To work around this you need to run cd <your_project>.git && touch <some_random_file> && git add <some_random_file> && git commit && git push origin master. (Note that you might need to configure your username and email for that machine's git if you hadn't done so in the past. The actual commands to run will be in the error message you get so I'll just omit them.)

So at this point you can clone the repository to any machine simply by running git clone <user>@<server>:<relative_path><your_project>.git. (As others have pointed out you might need to prefix it with ssh:// if you use the absolute path.) This assumes that you can already log in from your client to the server. (You'll also get bonus points for setting up a config file and keys for ssh, if you intend to push a lot of stuff to the remote server.)

Some relevant links:
This pretty much tells you what you need to know.
And this is for those who know the basic workings of git but sometimes forget the exact syntax.

I had this same issue, and searched the internet for a solution and none of the suggestions didn’t not open by double clicking the .jar file.

In my case the reason is I have multiple JDK & JRE versions installed on my computer. Since I am a software developer working with several different versions for different clients I need to use multiple JDKs in my PC (Windows 10 Pro). So I do not want to change the system variables (i.e. JAVA_HOME, JRE_HOME or PATH), instead I use command prompt to run java in user process whenever I wanted to use a different version.

When installing JDK it registers the .jar file association with latest version we installed in the PC. If you right click on the .jar icon and select properties, it will show that file opens with “Java(TM) Platform SE Binary”. If we look at the registry key: HKEY_CLASSES_ROOT\jarfile\shell\open\command, it will point to latest JDK version.

It is not a good idea (sometimes annoying) to change the registry key every time I want to run an app build from a different version.

So in my situation it is impossible to just double click the .jar file to execute it. But instead I found a work around solution myself.

Scenario:

Multiple JDKs (1.7, 1.8, 9.0, 10.0, 11.0, and 12.0)are installed in the PC, so the latest installed was 12.0.

Problem

Want to double click an executable .jar developed using JDK 1.8 and didn’t work

This is my work around solution:

1. Create a shortcut for the .jar file that you want to open.
2. Right click the shortcut icon and select properties -> Shortcut tab

3. Change the text in the target (for example "D:\Dev\JavaApp1.8.jar") To

   "C:\Program Files\Java\jdk1.8.0\bin\javaw.exe" -jar "D:\Dev\JavaApp1.8.jar"

4. Then click ok Double click the shortcut.

It should now open the app.

As already mentioned in multiple answers, using virtualenv is a clean solution. However a small pitfall that everyone should be aware of is that if an alias for python is set in bash_aliases like:

python=python3.6

this alias will also be used inside the virtual environment. So in this scenario running python -V inside the virtual env will always output 3.6 regardless of what interpreter is used to create the environment:

virtualenv venv --python=pythonX.X

After iterating the whole file with csv.reader() method, you have the total number of lines read, via instance variable line_num:

import csv
with open('csv_path_file') as f:
    csv_reader = csv.reader(f)
    for row in csv_reader:
        pass
    print(csv_reader.line_num)

Quoting the official documentation:

csvreader.line_num

The number of lines read from the source iterator.

Small caveat:

• total number of lines, includes the header, if the CSV has.

Instead of instantiating the FileUpload in your code behind file, just declare it in your markup file (.aspx file):

<asp:FileUpload ID="fileUpload" runat="server" />

Then you will be able to access all of the properties of the control, such as HasFile.

I write this code and It's worked for me .

public static string ExcutePushNotification(string title, string msg, string fcmToken, object data) 
{

        var serverKey = "AAAA*******************";
        var senderId = "3333333333333";


        var result = "-1";

        var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://fcm.googleapis.com/fcm/send");
        httpWebRequest.ContentType = "application/json";
        httpWebRequest.Headers.Add(string.Format("Authorization: key={0}", serverKey));
        httpWebRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
        httpWebRequest.Method = "POST";


        var payload = new
        {
            notification = new
            {
                title = title,
                body = msg,
                sound = "default"
            },

            data = new
            {
                info = data
            },
            to = fcmToken,
            priority = "high",
            content_available = true,

        };


        var serializer = new JavaScriptSerializer();

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = serializer.Serialize(payload);
            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            result = streamReader.ReadToEnd();
        }
        return result;
}

The noscript tag works well, but will require each additional page request to continue serving useless JS files, since essentially noscript is a client side check.

You could set a cookie with JS, but as someone else pointed out, this could fail. Ideally, you'd like to be able to detect JS client side, and without using cookies, set a session server side for that user that indicates is JS is enabled.

A possibility is to dynamically add a 1x1 image using JavaScript where the src attribute is actually a server side script. All this script does is saves to the current user session that JS is enabled ($_SESSION['js_enabled']). You can then output a 1x1 blank image back to the browser. The script won't run for users who have JS disabled, and hence the $_SESSION['js_enabled'] won't be set. Then for further pages served to this user, you can decide whether to include all of your external JS files, but you'll always want to include the check, since some of your users might be using the NoScript Firefox add-on or have JS disabled temporarily for some other reason.

You'll probably want to include this check somewhere close to the end of your page so that the additional HTTP request doesn't slow down the rendering of your page.

I have a visual Basic program with Visual Studio 2008 that uses an Access 2007 database and was receiving the same error. I found some threads that advised changing the advanced compile configuration to x86 found in the programs properties if you're running a 64 bit system. So far I haven't had any problems with my program since.

You can read from file to map, where the key is the date and skip if the the whole row if the date is already in map

        Map<String, List<String>> map = new HashMap<String, List<String>>();

        int i = 0;
        String lastData = null;
        while (s.hasNext()) {
            String str = s.next();
            if (i % 13 == 0) {
                if (map.containsKey(str)) {
                    //skip the whole row
                    lastData = null;
                } else {
                    lastData = str;
                    map.put(lastData, new ArrayList<String>());
                }
            } else if (lastData != null) {
                map.get(lastData).add(str);
            }


            i++;
        }

You can use valgrind to debug it.

#include<stdio.h>
#include<stdlib.h>

int main()
{
 char *x = malloc(100);
 free(x);
 free(x);
 return 0;

From PEP 8 - Style Guide for Python Code:

The preferred way of wrapping long lines is by using Python's implied line continuation inside parentheses, brackets and braces. If necessary, you can add an extra pair of parentheses around an expression, but sometimes using a backslash looks better. Make sure to indent the continued line appropriately.

Example of implicit line continuation:

a = some_function(
    '1' + '2' + '3' - '4')

On the topic of line-breaks around a binary operator, it goes on to say:-

For decades the recommended style was to break after binary operators. But this can hurt readability in two ways: the operators tend to get scattered across different columns on the screen, and each operator is moved away from its operand and onto the previous line.

In Python code, it is permissible to break before or after a binary operator, as long as the convention is consistent locally. For new code Knuth's style (line breaks before the operator) is suggested.

Example of explicit line continuation:

a = '1'   \
    + '2' \
    + '3' \
    - '4'

i have same problem and i think just set width and height programmatically :

set width of button's with metrics.widthPixels / 2 metrics is object of DisplayMetrics.

 GridLayout gridLayout=findViewById(R.id.grid);
    for (int i = 0; i <gridLayout.getChildCount() ; i++) {
        View view= gridLayout.getChildAt(i);
        if(view instanceof Button){
            Button btn = (Button) view;
            btn.setWidth(200);//metrics.widthPixels / 2
            btn.setHeight(200);//metrics.heightPixels / 7
        }
    }

Following up on these solutions, here is some helpful code illustrating :

#
# Copying columns in pandas without slice warning
#
import numpy as np
df = pd.DataFrame(np.random.randn(10, 3), columns=list('ABC'))

#
# copies column B into new column D
df.loc[:,'D'] = df['B']
print df

#
# creates new column 'E' with values -99
# 
# But copy command replaces those where 'B'>0 while others become NaN (not copied)
df['E'] = -99
print df
df['E'] = df[df['B']>0]['B'].copy()
print df

#
# creates new column 'F' with values -99
# 
# Copy command only overwrites values which meet criteria 'B'>0
df['F']=-99
df.loc[df['B']>0,'F'] = df[df['B']>0]['B'].copy()
print df

I think the even shorter answer that you'll like is: StringUtils.isBlank(acct);

From the documentation: http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/StringUtils.html#isBlank%28java.lang.String%29

isBlank
public static boolean isBlank(String str)
Checks if a String is whitespace, empty ("") or null.

 StringUtils.isBlank(null)      = true
 StringUtils.isBlank("")        = true
 StringUtils.isBlank(" ")       = true
 StringUtils.isBlank("bob")     = false
 StringUtils.isBlank("  bob  ") = false
 
Parameters:
str - the String to check, may be null
Returns:
true if the String is null, empty or whitespace

Add the annotation @ResponseBody to your method return.

If you are using third party libraries with your project or if you have problems with creating MANIFEST.MF file properly, there can be conflicts when running JAR files generated using

File > Project Structure > Artifacts > '+' > JAR > From modules with dependencies > .....

method mentioned above.

Instead I suggest you to create an empty JAR and add all other elements to the output root manually. A wonderful blog article for this method can be found here: http://karthicraghupathi.com/2016/07/10/creating-an-executable-jar-in-intellij-idea/ I tried the steps mentioned there and everything worked fine for me!

You could also use the .add() function:

 df.loc[:,'variance'] = df.loc[:,'budget'].add(df.loc[:,'actual'])

I was recently struggling with a similar problem. It turned out that the database was missing indexes on foreign keys. That caused Oracle to lock many more records than required which quickly led to a deadlock during high concurrency.

Here is an excellent article with lots of good detail, suggestions, and details about how to fix a deadlock: http://www.oratechinfo.co.uk/deadlocks.html#unindex_fk

Yes, just delete the branch by running git push origin :branchname. To fix a new issue later, branch off from master again.

If your Spinner was populated by SQLite cursor, then the solution is:

Spinner mySpin = (Spinner) findViewById(R.id.myspin);
mySpin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {  
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
           SQLiteCursor item = (SQLiteCursor) parent.getItemAtPosition(position);
           String value = String.valueOf(item.getString(0));
           Toast.makeText(getApplicationContext(), "The option is:" + value , Toast.LENGTH_SHORT).show(); 
 }

PS: In item.getString(0) -> 0 is the index of column on cursor that you want to get.

First you need to get rid of all newline characters in all your text nodes. Then you can use an identity transform to output your DOM tree. Look at the javadoc for TransformerFactory#newTransformer().

Try to run Maven from the command line or type "-X" in the text field - you can't break anything this way, at the worst, you'll get an error (I don't have Netbeans; in Eclipse, there is a checkbox "Debug" for this).

When running with debug output enabled, you should see the paths which the exec-maven-plugin plugin uses.

The next step would then be to copy the command into a command prompt or terminal and execute it manually to see if you get a useful error message there.

For O(1) complexity of head,tail operation you should use deque however.

Following way:

from collections import deque
l = deque([1,2,3,4,5,6,7,8,9])
head, tail = l.popleft(), l

It's useful when you must iterate through all elements of the list. For example in naive merging 2 partitions in merge sort.

Update your cordova to the latest version and the issue should be resolved. In case the issue not resolved please set the path in the environment variable (in case of Windows). Example: System Variable Value name GRADLE_HOME Value D:\Android\Android Studio\gradle\gradle-4.3.1 (please replace with your path)

Use position: fixed, and anchor it to the top and right sides of the page:

#fixed-div {
    position: fixed;
    top: 1em;
    right: 1em;
}

IE6 does not support position: fixed, however. If you need this functionality in IE6, this purely-CSS solution seems to do the trick. You'll need a wrapper <div> to contain some of the styles for it to work, as seen in the stylesheet.

InetAddress.isReachable() according to javadoc:

".. A typical implementation will use ICMP ECHO REQUESTs if the privilege can be obtained, otherwise it will try to establish a TCP connection on port 7 (Echo) of the destination host..".

Option #1 (ICMP) usually requires administrative (root) rights.

This is totally valid, I do it all the time. I usually use IllegalArguemntException if it is a result of parameter checking.

In this case I wouldn't suggest asserts because they are turned off in a deployment build and you always want to stop this from happening, but they are valid if your group does ALL it's testing with asserts turned on and you think the chance of missing a parameter problem at runtime is more acceptable than throwing an exception that is maybe more likely to cause a runtime crash.

Also, an assert would be more difficult for the caller to trap, this is easy.

You probably want to list it as a "throws" in your method's javadocs along with the reason so that callers aren't surprised.

In JavaScript:

jQuery('#div_session_write').load('session_write.php?session_name=new_value');

In session_write.php file:

<?
session_start();

if (isset($_GET['session_name'])) {$_SESSION['session_name'] = $_GET['session_name'];}
?>

In HTML:

<div id='div_session_write'> </div>

arr = [1,9,5,2,4,9,5,8,7,9,0,8,2,7,5,8,0,2,9]
arr[rand(arr.count)]

This will return a random element from array.

If You will use the line mentioned below

arr[1+rand(arr.count)]

then in some cases it will return 0 or nil value.

The line mentioned below

rand(number)

always return the value from 0 to number-1.

If we use

1+rand(number)

then it may return number and arr[number] contains no element.

I agree that the best way is to use the one given by: David Chase, Cu Ly, and others that the simplest way to do this is to use the container: $(this) property as follows:

$(selectorString).each(function () {
  var $this = $(this);
  $this.popover({
    html: true,
    placement: "top",
    container: $this,
    trigger: "hover",
    title: "Popover",
    content: "Hey, you hovered on element"
  });
});

I want to point out here that the popover in this case will inherit all properties of the current element. So, for example, if you do this for a .btn element(bootstrap), you won't be able to select text inside the popover. Just wanted to record that since I spent quite some time banging my head on this.

Try to copy the file in to your directory manually (C:\Users\Admin\AppData\Local\Temp\WebSitePublish\digisol--1147805695\obj\Debug\Package\PackageTmp.vs\digisol\v15\Server\sqlite3 )

Resources from src/main/resources will be put onto the root of the classpath, so you'll need to get the resource as:

new BufferedReader(new InputStreamReader(getClass().getResourceAsStream("/config.txt")));

You can verify by looking at the JAR/WAR file produced by maven as you'll find config.txt in the root of your archive.

This works:

var event = jQuery.Event('keypress');
event.which = 13; 
event.keyCode = 13; //keycode to trigger this for simulating enter
jQuery(this).trigger(event); 

a:hover, /* OPTIONAL*/
a:visited,
a:focus
{text-decoration: none !important;}

Also, for posterity -- Clang (like GCC) accepts the -x switch to set the language of the input files, for example,

$ clang -x c++ some_random_file.txt

This mailing list thread explains the difference between clang and clang++ well: Difference between clang and clang++

This is because your row variable/tuple does not contain any value for that index. You can try printing the whole list like print(row) and check how many indexes there exists.

This one helped me:

Another option can be to utilize the tagName property of the e.target. It doesn't apply exactly here, but let's say I have a class of something that's applied to either a DIV or an A tag, and I want to see if that class was clicked, and determine whether it was the DIV or the A that was clicked. I can do something like:

$('.example-class').click(function(e){
  if ((e.target.tagName.toLowerCase()) == 'a') {
    console.log('You clicked an A element.');
  } else { // DIV, we assume in this example
    console.log('You clicked a DIV element.');
  }
});

Dictionary<,> is the equivalent. While it doesn't have a Get(...) method, it does have an indexed property called Item which you can access in C# directly using index notation:

class Test {
  Dictionary<int,String> entities;

  public String getEntity(int code) {
    return this.entities[code];
  }
}

If you want to use a custom key type then you should consider implementing IEquatable<> and overriding Equals(object) and GetHashCode() unless the default (reference or struct) equality is sufficient for determining equality of keys. You should also make your key type immutable to prevent weird things happening if a key is mutated after it has been inserted into a dictionary (e.g. because the mutation caused its hash code to change).

Here is complete article about streaming android camera video to a webpage.

Android Streaming Live Camera Video to Web Page

1. Used libstreaming on android app
2. On server side Wowza Media Engine is used to decode the video stream
3. Finally jWplayer is used to play the video on a webpage.

for (Iterator<String> i = someIterable.iterator(); i.hasNext();) {
    String item = i.next();
    System.out.println(item);
}

Note that if you need to use i.remove(); in your loop, or access the actual iterator in some way, you cannot use the for ( : ) idiom, since the actual iterator is merely inferred.

As was noted by Denis Bueno, this code works for any object that implements the Iterable interface.

Also, if the right-hand side of the for (:) idiom is an array rather than an Iterable object, the internal code uses an int index counter and checks against array.length instead. See the Java Language Specification.

It depends what you mean by "it". The iterator knows what index it's reached, yes - in the case of a List<T> or an array. But there's no general index within IEnumerator<T>. Whether it's iterating over an indexed collection or not is up to the implementation. Plenty of collections don't support direct indexing.

(In fact, foreach doesn't always use an iterator at all. If the compile-time type of the collection is an array, the compiler will iterate over it using array[0], array[1] etc. Likewise the collection can have a method called GetEnumerator() which returns a type with the appropriate members, but without any implementation of IEnumerable/IEnumerator in sight.)

Options for maintaining an index:

• Use a for loop
• Use a separate variable

• Use a projection which projects each item to an index/value pair, e.g.

   foreach (var x in list.Select((value, index) => new { value, index }))
   {
       // Use x.value and x.index in here
   }
  

• Use my SmartEnumerable class which is a little bit like the previous option

All but the first of these options will work whether or not the collection is naturally indexed.

Here is the code to redirect to some other page with a timeout of 10 seconds.

<script>
    function Redirect()
    {
        window.location="http://www.adarshkr.com";
    }

    document.write("You will be redirected to a new page in 10 seconds.");
    setTimeout('Redirect()', 10000);
</script>

You can also do it like this, on click of a button using location.assign:

<input type="button" value="Load new document" onclick="newPage()">
<script>
    function newPage() {
        window.location.assign("http://www.adarshkr.com")
    }
</script>

I just used this:

grep -c $'\x0c' filename

To search for and count a page control character in the file..

So to include an offset in the output:

grep -b -o $'\x0c' filename | less

I am just piping the result to less because the character I am greping for does not print well and the less displays the results cleanly. Output example:

21:^L
23:^L
2005:^L

You can define attribute as BINARY or use INSTR or STRCMP to perform your search.

It's not possible to change user within a shell script. Workarounds using sudo described in other answers are probably your best bet.

If you're mad enough to run perl scripts as root, you can do this with the $< $( $> $) variables which hold real/effective uid/gid, e.g.:

#!/usr/bin/perl -w
$user = shift;
if (!$<) {
    $> = getpwnam $user;
    $) = getgrnam $user;
} else {
    die 'must be root to change uid';
}
system('whoami');

If you want a newline, you have to write one explicitly. The usual way is like this:

hs.write(name + "\n")

This uses a backslash escape, \n, which Python converts to a newline character in string literals. It just concatenates your string, name, and that newline character into a bigger string, which gets written to the file.

It's also possible to use a multi-line string literal instead, which looks like this:

"""
"""

Or, you may want to use string formatting instead of concatenation:

hs.write("{}\n".format(name))

All of this is explained in the Input and Output chapter in the tutorial.

Use chars:

Dim firstChar As char;
firstChar = s.Chars(0);

http://vb.net-informations.com/string/vb.net_String_Chars.htm

Try this from different folder:

sudo tar -cvjSf folder.tar.bz2 folder/*

$('#mainn').text(function (_,txt) {
    return txt.slice(0, -1);
});

First WebClient is easier to use; GET arguments are specified on the query-string - the only trick is to remember to escape any values:

        string address = string.Format(
            "http://foobar/somepage?arg1={0}&arg2={1}",
            Uri.EscapeDataString("escape me"),
            Uri.EscapeDataString("& me !!"));
        string text;
        using (WebClient client = new WebClient())
        {
            text = client.DownloadString(address);
        }

The project I'm working on, we do something like this. We use the errorlevel keyword so it kind of looks like:

call myExe.exe
if errorlevel 1 (
  goto build_fail
)

That seems to work for us. Note that you can put in multiple commands in the parens like an echo or whatever. Also note that build_fail is defined as:

:build_fail
echo ********** BUILD FAILURE **********
exit /b 1

In rails 4 you can now use a css and sass helper image-url:

div.logo {background-image: image-url("logo.png");}

If your background images aren't showing up consider looking at how you're referencing them in your stylesheets.

        This is the simple answer how to add datas dynamically in listview android kotlin


class MainActivity : AppCompatActivity(){
        
            var listItems = arrayListOf<String>()
            val array = arrayOf("a","b","c","d","e")
            var listView: ListView? = null
    
            private lateinit var adapter: listViewAdapter
        
            override fun onCreate(savedInstanceState: Bundle?) {
                super.onCreate(savedInstanceState)
                setContentView(R.layout.scrollview_layout)
        
                listItems.add("a")
                listItems.add("b")
                listItems.add("c")
                listItems.add("d")
                listItems.add("e")
        
                //if you want to add array items to a list you can try this for each loop
                for(items in array)
                    listItems.add(items)
                
                //check the result in console
                Log.e("TAG","listItems array: $listItems")
    
            adapter = ListViewAdapter()
            adapter.updateList(listItems)
            adapter.notifyDataSetChanged()
        
            }
        }


//Here is the adapter class
    class ListviewAdapter : BaseAdapter(){
    
    private var itemsList = arrayListOf<String>()
    
    override fun getView(position: Int, container: View?, parent: ViewGroup?): View {
            var view  = container
            val inflater = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater

        }
       
    //Here I just explained two ways, we can do this many ways.

Sadly @Andrés Montoya answer has a flaw which is related to how he compares the obj. I found a solution here which should solve this:

const now = Date.now().valueOf() / 1000

if (typeof decoded.exp !== 'undefined' && decoded.exp < now) {
    throw new Error(`token expired: ${JSON.stringify(decoded)}`)
}
if (typeof decoded.nbf !== 'undefined' && decoded.nbf > now) {
    throw new Error(`token expired: ${JSON.stringify(decoded)}`)
}

Thanks to thejohnfreeman!

So I just wondered about the same, but had at the same time had a solution to this. I wanted a query that included all rows in the table and counting both blanks and non blanks. So I came up with this.

SELECT COUNT(col_name)                                 VALUE_COUNT
       COUNT(NVL(col_name, 'X') - COUNT(col_name)      NULL_VALUE_COUNT
FROM   table
[CONDITIONS]

Instead of the NVL function you can count the primary key column to obtain the total count of rows

It works like a charm

Use re.findall or re.finditer instead.

re.findall(pattern, string) returns a list of matching strings.

re.finditer(pattern, string) returns an iterator over MatchObject objects.

Example:

re.findall( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')
# Output: ['cats', 'dogs']

[x.group() for x in re.finditer( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')]
# Output: ['all cats are', 'all dogs are']

This function get id off a page current.

get_the_ID();

just try

<img :src="require(`${imgPreUrl}img/logo.png`)">

just use this simple code :

NSArray *hasDuplicates = /* (...) */;
NSArray *noDuplicates = [[NSSet setWithArray: hasDuplicates] allObjects];

since nsset doesn't allow duplicate values and all objects returns an array

dataset = dataset.dropna(axis=0, how='any', thresh=None, subset=None, inplace=False)

This worked for me

In Chrome, on the right-hand side of the URL bar when you are at a password protected URL, you should see a small key symbol. Click the symbol and it will take you directly to the Password Management area where you can remove the entry. That will ensure you receive future prompts or have an opportunity to enter a new password and save it.

If you do not see the key symbol, that same Password Management area can be accessed by going to Chrome -> Settings -> Passwords and forms -> Manage Passwords. Or more simply, this URL – chrome://settings/passwords.

I think you can reset the invocations using Mockito.reset(mockLog). You should call this before every test, so inside @Before would be a good place.

O(1): finding the best next move in Chess (or Go for that matter). As the number of game states is finite it's only O(1) :-)

This code (example) :

    Chronology ch1 = GregorianChronology.getInstance();     Chronology ch2 = ISOChronology.getInstance();      DateTime dt = new DateTime("2013-12-31T22:59:21+01:00",ch1);     DateTime dt2 = new DateTime("2013-12-31T22:59:21+01:00",ch2);      System.out.println(dt);     System.out.println(dt2);      boolean b = dt.equals(dt2);      System.out.println(b); 

Will print :

2013-12-31T16:59:21.000-05:00 2013-12-31T16:59:21.000-05:00 false 

You are probably comparing two DateTimes with same date but different Chronology.

Create a File object, passing the directory path to the constructor. Use the listFiles() to retrieve an array of File objects for each file in the directory, and then call the getName() method to get the filename.

List<String> results = new ArrayList<String>();


File[] files = new File("/path/to/the/directory").listFiles();
//If this pathname does not denote a directory, then listFiles() returns null. 

for (File file : files) {
    if (file.isFile()) {
        results.add(file.getName());
    }
}

When none of the if test in number_translator() evaluate to true, the function returns None. The error message is the consequence of that.

Whenever you see an error that include 'NoneType' that means that you have an operand or an object that is None when you were expecting something else.

emulator -writable-system

For people using an Emulator: Another possibility is that you need to start the emulator with -writable-system. That was the only thing that worked for me when using the standard emulator packaged with android studio with a 4.1 image. Check here: https://stackoverflow.com/a/41332316/4962858

There is a NuGet package named StrongNamer by Daniel Plaisted that seems to do the trick.

Is the simplest solution that I've found so far.

There are also a number of other NuGet packages to fix the strong naming problem such as Brutal.Dev.StrongNameSigner by Werner van Deventer, but I have not tested that one or any of the others.

I just found this :

 private static bool TrySetSuppressScriptErrors(WebBrowser webBrowser, bool value)
    {
        FieldInfo field = typeof(WebBrowser).GetField("_axIWebBrowser2", BindingFlags.Instance | BindingFlags.NonPublic);
        if (field != null)
        {
            object axIWebBrowser2 = field.GetValue(webBrowser);
            if (axIWebBrowser2 != null)
            {
                axIWebBrowser2.GetType().InvokeMember("Silent", BindingFlags.SetProperty, null, axIWebBrowser2, new object[] { value });
                return true;
            }
        }

        return false;
    }

usage example to set webBrowser to silent : TrySetSuppressScriptErrors(webBrowser,true)

Just use the location.host property

switch (location.host) {
    case "xxx.local":
        settings = ...
        break;
    case "xxx.dev.yyy.com":
        settings = ...
        break;
}

You can use the EXACT Function for exact string comparisons.

=IF(EXACT(A1, "ENG"), 1, 0)

len(repr(float(x)/3))

However I must say that this isn't as reliable as you think.

Floats are entered/displayed as decimal numbers, but your computer (in fact, your standard C library) stores them as binary. You get some side effects from this transition:

>>> print len(repr(0.1))
19
>>> print repr(0.1)
0.10000000000000001

The explanation on why this happens is in this chapter of the python tutorial.

A solution would be to use a type that specifically tracks decimal numbers, like python's decimal.Decimal:

>>> print len(str(decimal.Decimal('0.1')))

1.) Create an arraylist of appropriate type, in this case i.e String

2.) Create a JSONObject while passing your string to JSONObject constructor as input

• As JSONObject notation is represented by braces i.e {}
• Where as JSONArray notation is represented by square brackets i.e []

3.) Retrieve JSONArray from JSONObject (created at 2nd step) using "interests" as index.

4.) Traverse JASONArray using loops upto the length of array provided by length() function

5.) Retrieve your JSONObjects from JSONArray using getJSONObject(index) function

6.) Fetch the data from JSONObject using index '"interestKey"'.

Note : JSON parsing uses the escape sequence for special nested characters if the json response (usually from other JSON response APIs) contains quotes (") like this

`"{"key":"value"}"`

should be like this

`"{\"key\":\"value\"}"`

so you can use JSONParser to achieve escaped sequence format for safety as

JSONParser parser = new JSONParser();
JSONObject json = (JSONObject) parser.parse(inputString);

Code :

JSONParser parser = new JSONParser();
String response = "{interests : [{interestKey:Dogs}, {interestKey:Cats}]}";

JSONObject jsonObj = (JSONObject) parser.parse(response);

or

JSONObject jsonObj = new JSONObject("{interests : [{interestKey:Dogs}, {interestKey:Cats}]}");

List<String> interestList = new ArrayList<String>();

JSONArray jsonArray = jsonObj.getJSONArray("interests");

for(int i = 0 ; i < jsonArray.length() ; i++){
    interestList.add(jsonArray.getJSONObject(i).optString("interestKey"));
}

Note : Sometime you may see some exceptions when the values are not available in appropriate type or is there is no mapping key so in those cases when you are not sure about the presence of value so use optString, optInt, optBoolean etc which will simply return the default value if it is not present and even try to convert value to int if it is of string type and vice-versa so Simply No null or NumberFormat exceptions at all in case of missing key or value

From docs

Get an optional string associated with a key. It returns the defaultValue if there is no such key.

 public String optString(String key, String defaultValue) {

  String missingKeyValue = json_data.optString("status","N/A");
  // note there is no such key as "status" in response
  // will return "N/A" if no key found 

or To get empty string i.e "" if no key found then simply use

  String missingKeyValue = json_data.optString("status");
  // will return "" if no key found where "" is an empty string

In general, Java doesn't have any global variables. Other than local variables, all variables comes under the scope of any class defined in the program. We can have static variables to have the scope of global variables.

Change the position attribute to fixed instead of absolute.

In addition to the accepted answer, one other check is to make sure that you have the right reference to your entity package in sessionFactory.setPackagesToScan(...) while setting up your session factory.

If you use bash, then the terminal history is saved in a file called .bash_history. Delete it, and history will be gone.

However, for MySQL the better approach is not to enter the password in the command line. If you just specify the -p option, without a value, then you will be prompted for the password and it won't be logged.

Another option, if you don't want to enter your password every time, is to store it in a my.cnf file. Create a file named ~/.my.cnf with something like:

[client]
user = <username>
password = <password>

Make sure to change the file permissions so that only you can read the file.

Of course, this way your password is still saved in a plaintext file in your home directory, just like it was previously saved in .bash_history.

In fact I would not use any REDIM, nor a loop for transferring data from sheet to array:

dim arOne()
arOne = range("A2:F1000")

or even

arOne = range("A2").CurrentRegion

and that's it, your array is filled much faster then with a loop, no redim.
