Just create this batch command file in your game directory. Bat file takes one argument %1 as the username.

Also, I use a splash screen to make pretty. You will NOT be able to play online, but who cares.

Adjust your memory usage to fit your machine (-Xmx & -Xmns).

If you have an element that does not have a specific selector and you still want to check if it is a descendant of another element, you can use jQuery.contains()

jQuery.contains( container, contained )
Description: Check to see if a DOM element is a descendant of another DOM element.

You can pass the parent element and the element that you want to check to that function and it returns if the latter is a descendant of the first.

As other answers mention, as for python 3.7+, the dict is ordered by definition. Instead of subclassing OrderedDict we can subclass abc.collections.MutableSet or typing.MutableSet using the dict's keys to store our values.

class OrderedSet(typing.MutableSet[T]):
    """A set that preserves insertion order by internally using a dict."""

    def __init__(self, iterable: t.Iterator[T]):
        self._d = dict.fromkeys(iterable)

    def add(self, x: T) -> None:
        self._d[x] = None

    def discard(self, x: T) -> None:
        self._d.pop(x)

    def __contains__(self, x: object) -> bool:
        return self._d.__contains__(x)

    def __len__(self) -> int:
        return self._d.__len__()

    def __iter__(self) -> t.Iterator[T]:
        return self._d.__iter__()

Then just:

x = OrderedSet([1, 2, -1, "bar"])
x.add(0)
assert list(x) == [1, 2, -1, "bar", 0]

I put this code in a small library, so anyone can just pip install it.

There's another short-cut you can use, although it can be inefficient depending on what's in your class instances.

As everyone has said the problem is that the multiprocessing code has to pickle the things that it sends to the sub-processes it has started, and the pickler doesn't do instance-methods.

However, instead of sending the instance-method, you can send the actual class instance, plus the name of the function to call, to an ordinary function that then uses getattr to call the instance-method, thus creating the bound method in the Pool subprocess. This is similar to defining a __call__ method except that you can call more than one member function.

Stealing @EricH.'s code from his answer and annotating it a bit (I retyped it hence all the name changes and such, for some reason this seemed easier than cut-and-paste :-) ) for illustration of all the magic:

import multiprocessing
import os

def call_it(instance, name, args=(), kwargs=None):
    "indirect caller for instance methods and multiprocessing"
    if kwargs is None:
        kwargs = {}
    return getattr(instance, name)(*args, **kwargs)

class Klass(object):
    def __init__(self, nobj, workers=multiprocessing.cpu_count()):
        print "Constructor (in pid=%d)..." % os.getpid()
        self.count = 1
        pool = multiprocessing.Pool(processes = workers)
        async_results = [pool.apply_async(call_it,
            args = (self, 'process_obj', (i,))) for i in range(nobj)]
        pool.close()
        map(multiprocessing.pool.ApplyResult.wait, async_results)
        lst_results = [r.get() for r in async_results]
        print lst_results

    def __del__(self):
        self.count -= 1
        print "... Destructor (in pid=%d) count=%d" % (os.getpid(), self.count)

    def process_obj(self, index):
        print "object %d" % index
        return "results"

Klass(nobj=8, workers=3)

The output shows that, indeed, the constructor is called once (in the original pid) and the destructor is called 9 times (once for each copy made = 2 or 3 times per pool-worker-process as needed, plus once in the original process). This is often OK, as in this case, since the default pickler makes a copy of the entire instance and (semi-) secretly re-populates it—in this case, doing:

obj = object.__new__(Klass)
obj.__dict__.update({'count':1})

—that's why even though the destructor is called eight times in the three worker processes, it counts down from 1 to 0 each time—but of course you can still get into trouble this way. If necessary, you can provide your own __setstate__:

    def __setstate__(self, adict):
        self.count = adict['count']

in this case for instance.

What ever instance you are using to call the void method , You can just use ,Verfiy

For Example:

In My case its _Log is the instance and LogMessage is the method to be tested:

try
{
    this._log.Verify(x => x.LogMessage(Logger.WillisLogLevel.Info, Logger.WillisLogger.Usage, "Created the Student with name as"), "Failure");
}
Catch 
{
    Assert.IsFalse(ex is Moq.MockException);
}

Is the Verify throws an exception due to failure of the method the test would Fail ?

I found the solution with following steps:

• remove the Oracle.DataAcces.dll reference,
  and add a fresh reference to:
  C:\windows\assembly\GAC\Oracle.DataAccess\X.XXX.X.XX__89b483f429c47342/oracle.dataaccess.dll
• Make local copy= false.

Hope it helps

To give you a different perspective on this, using throw is particularly useful if you're providing an API to a client and you want to provide verbose stack trace information for your internal library. By using throw here, I'd get the stack trace in this case of the System.IO.File library for File.Delete. If I use throw ex, then that information will not be passed to my handler.

static void Main(string[] args) {            
   Method1();            
}

static void Method1() {
    try {
        Method2();
    } catch (Exception ex) {
        Console.WriteLine("Exception in Method1");             
    }
}

static void Method2() {
    try {
        Method3();
    } catch (Exception ex) {
        Console.WriteLine("Exception in Method2");
        Console.WriteLine(ex.TargetSite);
        Console.WriteLine(ex.StackTrace);
        Console.WriteLine(ex.GetType().ToString());
    }
}

static void Method3() {
    Method4();
}

static void Method4() {
    try {
        System.IO.File.Delete("");
    } catch (Exception ex) {
        // Displays entire stack trace into the .NET 
        // or custom library to Method2() where exception handled
        // If you want to be able to get the most verbose stack trace
        // into the internals of the library you're calling
        throw;                
        // throw ex;
        // Display the stack trace from Method4() to Method2() where exception handled
    }
}

Please use:

logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type=TRACE
spring.jpa.show-sql=true

Client need to notify that it finished sending, using socket.shutdown (not socket.close which close both reading/writing part of the socket):

...
print "Done Sending"
s.shutdown(socket.SHUT_WR)
print s.recv(1024)
s.close()

UPDATE

Client sends Hello server! to the server; which is written to the file in the server side.

s.send("Hello server!")

Remove above line to avoid it.

Be sure to supply the exact same path as when you set it, i.e.

Setting:

$.cookie('foo','bar', {path: '/'});

Removing:

$.cookie('foo', null, {path: '/'});

Note that

$.cookie('foo', null); 

will NOT work, since it is actually not the same cookie.

Hope that helps. The same goes for the other options in the hash

After doing everything in the above answers, I figured out I was not running Visual Studio as Admin. After running as Admin, problem solved.

I stumbled on this post looking for a nice way to keep my header/navigation bar centered and responsive to size changes.

//CSS
.nav-container {
  height: 60px;  /*The static height*/
  width: 100%;  /*Makes it responsive to resizing the browser*/
  position: fixed;  /*So that it will always be in the center*/
}

//jQuery
$(window).scroll(() => {
  if ($(document).scrollTop() < 60) {
    $('.nav-container').css('top', $(document).scrollTop() * -1)
  }
})

As we scroll, the bar moves upwards off the screen. If you scroll left/right it will stay fixed.

Surprised this wasn't mentioned yet:

import os
fn = '/some/path/a.tar.gz'

basename = os.path.basename(fn)  # os independent
Out[] a.tar.gz

base = basename.split('.')[0]
Out[] a

ext = '.'.join(basename.split('.')[1:])   # <-- main part

# if you want a leading '.', and if no result `None`:
ext = '.' + ext if ext else None
Out[] .tar.gz

Benefits:

• Works as expected for anything I can think of
• No modules
• No regex
• Cross-platform
• Easily extendible (e.g. no leading dots for extension, only last part of extension)

As function:

def get_extension(filename):
    basename = os.path.basename(filename)  # os independent
    ext = '.'.join(basename.split('.')[1:])
    return '.' + ext if ext else None

In my rare case it was color wrapper who spoiled gcc. Solved by disabling cw excluding its directory /usr/libexec/cw from PATH environmental variable.

As @NaturalBornCamper said, mysql_insert_id is now deprecated and should not be used. The options are now to use either PDO or mysqli. NaturalBornCamper explained PDO in his answer, so I'll show how to do it with MySQLi (MySQL Improved) using mysqli_insert_id.

// First, connect to your database with the usual info...
$db = new mysqli($hostname, $username, $password, $databaseName);
// Let's assume we have a table called 'people' which has a column
// called 'people_id' which is the PK and is auto-incremented...
$db->query("INSERT INTO people (people_name) VALUES ('Mr. X')");
// We've now entered in a new row, which has automatically been 
// given a new people_id. We can get it simply with:
$lastInsertedPeopleId = $db->insert_id;
// OR
$lastInsertedPeopleId = mysqli_insert_id($db);

Check out the PHP documentation for more examples: http://php.net/manual/en/mysqli.insert-id.php

There is also proc.time()

You can use in the same way as Sys.time but it gives you a similar result to system.time.

ptm <- proc.time()
#your function here
proc.time() - ptm

the main difference between using

system.time({ #your function here })

is that the proc.time() method still does execute your function instead of just measuring the time... and by the way, I like to use system.time with {} inside so you can put a set of things...

From Blogging Developer:

In order to understand the difference between keydown and keypress, it is useful to understand the difference between a "character" and a "key". A "key" is a physical button on the computer's keyboard while a "character" is a symbol typed by pressing a button. In theory, the keydown and keyup events represent keys being pressed or released, while the keypress event represents a character being typed. The implementation of the theory is not same in all browsers.

Note: You can also try out the Key Event Tester (available on the above-mentioned site) to understand this concept.

Doing without the -u and -p worked for me (when I was logged in as root):

mysqldump --opt mydbname > mydbname.sql

I've tried different cases and only when owner was set to nginx (chown -R nginx:nginx "/var/www/myfolder") - it started to work as expected.

I have read all answers, but this link was more clear explanation for me about difference between CPU(Processor) and Core. So I'm leaving here some notes from there.

The main difference between CPU and Core is that the CPU is an electronic circuit inside the computer that carries out instruction to perform arithmetic, logical, control and input/output operations while the core is an execution unit inside the CPU that receives and executes instructions.

follow the below steps in Intellij (with screenshots for better understanding):

1. go to Files --> Project structure

2. navigate to modules and now select the module, in which your Junit test file present and select "Use module compile output path" radio button.

3. Mention the respective classes folder path, similar to the screenshot attached.

4. Do apply and Okay. This worked for me!

From Using Triggers:

Detecting the DML Operation That Fired a Trigger

If more than one type of DML operation can fire a trigger (for example, ON INSERT OR DELETE OR UPDATE OF Emp_tab), the trigger body can use the conditional predicates INSERTING, DELETING, and UPDATING to check which type of statement fire the trigger.

So

IF DELETING THEN ... END IF;

should work for your case.

In cmd, you can do this:

copy one.txt+two.txt+three.txt four.txt

In PowerShell this would be:

cmd /c copy one.txt+two.txt+three.txt four.txt

While the PowerShell way would be to use gc, the above will be pretty fast, especially for large files. And it can be used on on non-ASCII files too using the /B switch.

var bd = document.getElementsByTagName('body')[0];
var time = new Date().getTime();

bd.onmousemove = goLoad;
function goLoad() {
if(new Date().getTime() - time >= 1200000) {
    time = new Date().getTime();
    window.location.reload(true);
    }else{
        time = new Date().getTime();
    }
}

Each time you move the mouse it will check the last time you moved the mouse. If the time interval is greater than 20' it will reload the page, else it will renew the last-time-you-moved-the-mouse.

Since one div is initially hidden, you can simply call toggle for both divs:

<a href="javascript:void(0);" id="forgot-password">forgot password?</a>
<div id="login-form">login form</div>

<div id="recover-password" style="display:none;">recover password</div>

<script type="text/javascript">
$(function(){
  $('#forgot-password').click(function(){
     $('#login-form').toggle();
     $('#recover-password').toggle(); 
  });
});
</script>

You can try using the standard W3C way:

.transition { transition: all 0.2s, top 0s, left 0s, width 0s, height 0s; }

http://jsfiddle.net/H2jet/60/

You could do a simple calculation, pimped with an regex, if the chosen date format is 'YYYYMM':

echo $(($(date +"%Y%m") - 1)) | sed -e 's/99$/12/'

In January of 2020 it will return 201912 ;-) But, it's only a workaround, when date does not have calculation options and other dateinterpreter options (e.g. using perl) not available ;-)

For even more robustness:

function getIframeWindow(iframe_object) {
  var doc;

  if (iframe_object.contentWindow) {
    return iframe_object.contentWindow;
  }

  if (iframe_object.window) {
    return iframe_object.window;
  } 

  if (!doc && iframe_object.contentDocument) {
    doc = iframe_object.contentDocument;
  } 

  if (!doc && iframe_object.document) {
    doc = iframe_object.document;
  }

  if (doc && doc.defaultView) {
   return doc.defaultView;
  }

  if (doc && doc.parentWindow) {
    return doc.parentWindow;
  }

  return undefined;
}

and

...
var el = document.getElementById('targetFrame');

var frame_win = getIframeWindow(el);

if (frame_win) {
  frame_win.targetFunction();
  ...
}
...

have you checked RSE (Remote System Explorer) ? I think it's pretty close to what you want to achieve.

I agree this one isn't immediate when you first look at it, but it's fairly simple when you get down to it.

Base case: your tower is of size 1. So you can do it in one move, from source directly to dest.

Recursive case: your tower is of size n > 1. So you move the top tower of size n-1 to an extra peg (by), move the bottom "tower" of size 1 to the destination peg, and move the top tower from by to dest.

So with a simple case, you have a tower of height 2:

 _|_    |     |
__|__   |     |
===== ===== =====

First step: move the top tower of 2-1 (=1) to the extra peg (the middle one, lets say).

  |     |     |
__|__  _|_    |
===== ===== =====

Next: move the bottom disc to the destination:

  |     |     |
  |    _|_  __|__
===== ===== =====

And finally, move the top tower of (2-1)=1 to the destination.

  |     |    _|_
  |     |   __|__
===== ===== =====

If you think about it, even if the tower were 3 or more, there will always be an empty extra peg, or a peg with all larger discs, for the recursion to use when swapping towers around.

I had the same problem but got round it by setting AutoPostBack to true and in an update panel set the trigger to the dropdownlist control id and event name to SelectedIndexChanged e.g.

    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" enableViewState="true">
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="ddl1" EventName="SelectedIndexChanged" />
        </Triggers>
        <ContentTemplate>
            <asp:DropDownList ID="ddl1" runat="server" ClientIDMode="Static" OnSelectedIndexChanged="ddl1_SelectedIndexChanged" AutoPostBack="true" ViewStateMode="Enabled">
                <asp:ListItem Text="--Please select a item--" Value="0" />
            </asp:DropDownList>
        </ContentTemplate>
    </asp:UpdatePanel>

I'll make this pretty simple for you. When a transaction is initiated, it goes under processing stage until it reaches the terminal stage. Once it reaches the terminal stage, the transaction status is posted by the payment gateway to the callback url which generally the merchants use as a reference to show the success/failure page to the user. Hope this helps?

Old question but heck, the simplest solution is:

1. Open CSV in Notepad
2. Save As -> select the right encoding
3. Open the new file

If you're running Jenkins inside a docker container and your Jenkins is linking to the host docker then you can fix that just by the Dockerfile below:

Bootstrap 4

Now that BS4 is flexbox, the fixed-fluid is simple. Just set the width of the fixed column, and use the .col class on the fluid column.

.sidebar {
    width: 180px;
    min-height: 100vh;
}

<div class="row">
    <div class="sidebar p-2">Fixed width</div>
    <div class="col bg-dark text-white pt-2">
        Content
    </div>
</div>

Bootstrap 3..

One approach to a fixed-fluid layout is using media queries that align with Bootstrap's breakpoints so that you only use the fixed width columns are larger screens and then let the layout stack responsively on smaller screens...

@media (min-width:768px) {
  #sidebar {
      min-width: 300px;
      max-width: 300px;
  }
  #main {
      width:calc(100% - 300px);
  }
}

Try this:

var charArray = "this is a test".ToCharArray().Select(c=>c.ToString());

You can use require as well to render images like

//then in the render function of Jsx insert the mainLogo variable

class NavBar extends Component {
  render() {
    return (
      <nav className="nav" style={nbStyle}>
        <div className="container">
          //right below here
          <img src={require('./logoWhite.png')} style={nbStyle.logo} alt="fireSpot"/>
        </div>
      </nav>
    );
  }
}

As said before, List provides functionality to add elements in a clean way, to do the same with arrays, you have to resize them to accomodate extra elements, see code below:

int[] arr = new int[2];
arr[0] = 1;
arr[1] = 2;
//without this line we'd get a exception
Array.Resize(ref arr, 3);
arr[2] = 3;

Regarding your idea with loop:

elements of an array are set to their default values when array is initialized. So your approach would be good, if you want to fill "blanks" in array holding reference types (which have default value null).

But it wouldn't work with value types, as they are initialized with 0!

1. Create a new project..
2. Right Click on your project..
3. Select Build path --> Configure Build Path
4. Under source tab choose link source, your .java files containing folder..

I am suggesting this since none of the methods that you tried have worked ---FYI

This is a working code

imageView.setDrawingCacheEnabled(true);
imageView.buildDrawingCache();
Bitmap bitmap = Bitmap.createBitmap(imageView.getDrawingCache());

Use "\\" to escape the \ character.

I found the best way to do this is with ChronoUnit.

long minutes = ChronoUnit.MINUTES.between(fromDate, toDate);
long hours = ChronoUnit.HOURS.between(fromDate, toDate);

King King's answer is of course right. Also Tim Schmelter's comment is also good suggestion in your case.

But if you want really remove last comma in a string, you should find the index of last comma and remove like;

string s = "1,5,12,34,12345";
int index = s.LastIndexOf(',');
Console.WriteLine(s.Remove(index, 1));

Output will be;

1,5,12,3412345

Here a demonstration.

It is too unlikely you want this way but I want to point it. And remember, String.Remove method doesn't remove any character in original string, it returns new string.

Try this JQuery code to dynamically include form, field, and delete/remove behavior:

$(document).ready(function() {_x000D_
    var max_fields = 10;_x000D_
    var wrapper = $(".container1");_x000D_
    var add_button = $(".add_form_field");_x000D_
_x000D_
    var x = 1;_x000D_
    $(add_button).click(function(e) {_x000D_
        e.preventDefault();_x000D_
        if (x < max_fields) {_x000D_
            x++;_x000D_
            $(wrapper).append('<div><input type="text" name="mytext[]"/><a href="#" class="delete">Delete</a></div>'); //add input box_x000D_
        } else {_x000D_
            alert('You Reached the limits')_x000D_
        }_x000D_
    });_x000D_
_x000D_
    $(wrapper).on("click", ".delete", function(e) {_x000D_
        e.preventDefault();_x000D_
        $(this).parent('div').remove();_x000D_
        x--;_x000D_
    })_x000D_
});

If you're already logged into the command line client try this:

mysql> select user();

It will output something similar to this:

+----------------+
| user()         |
+----------------+
| root@localhost |
+----------------+
1 row in set (0.41 sec)

In my example above, I was logged in as root from localhost.

To find port number and other interesting settings use this command:

mysql> show variables;

error MSB6006: "cmd.exe" exited with code -Solved

I also face this problem . In my case it is due to output exe already running .I solved my problem simply close the application instance before building.

Assuming the items are hashable

>>> from collections import Counter
>>> not Counter([1, 2]) - Counter([1])
False
>>> not Counter([1, 2]) - Counter([1, 2])
True
>>> not Counter([1, 2, 2]) - Counter([1, 2])
False

If you don't care about duplicate items eg. [1, 2, 2] and [1, 2] then just use:

>>> set([1, 2, 2]).issubset([1, 2])
True

Is testing equality on the smaller list after an intersection the fastest way to do this?

.issubset will be the fastest way to do it. Checking the length before testing issubset will not improve speed because you still have O(N + M) items to iterate through and check.

You can use gsub to replace multiple mutations of empty, like "" or a space, to be NA:

data= data.frame(cats=c('', ' ', 'meow'), dogs=c("woof", " ", NA))
apply(data, 2, function(x) gsub("^$|^ $", NA, x))

If using mvn, check that you have the correct scope (if you have that defined) in your pom.xml. I once had it incorrectly set to test but needed it for runtime.

@FindBy(xpath = "//span[@class='y2' and contains(text(), 'Your Text')] ") 
private WebElementFacade emailLinkToVerifyAccount;

This approach will work for you, hopefully.

Adding to Micah Carrick answer for django 1.8:

if settings.DEBUG:
  urlpatterns.append(url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}))

If anybody is looking for Java firestore sdk solution to add items in array field:

List<String> list = java.util.Arrays.asList("A", "B");
Object[] fieldsToUpdate = list.toArray();
DocumentReference docRef = getCollection().document("docId");
docRef.update(fieldName, FieldValue.arrayUnion(fieldsToUpdate));

To delete items from array user: FieldValue.arrayRemove()

The standard way to pass a list of values as URL parameters is to repeat them:

http://our.api.com/Product?id=101404&id=7267261

Most server code will interpret this as a list of values, although many have single value simplifications so you may have to go looking.

Delimited values are also okay.

If you are needing to send JSON to the server, I don't like seeing it in in the URL (which is a different format). In particular, URLs have a size limitation (in practice if not in theory).

The way I have seen some do a complicated query RESTfully is in two steps:

1. POST your query requirements, receiving back an ID (essentially creating a search criteria resource)
2. GET the search, referencing the above ID
3. optionally DELETE the query requirements if needed, but note that they requirements are available for reuse.

Every process running under the Linux kernel receives its own, unique environment that it inherits from its parent. In this case, the parent will be either a shell itself (spawning a sub shell), or the 'login' program (on a typical system).

As each process' environment is protected, there is no way to 'inject' an environmental variable to every running process, so even if you modify the default shell .rc / profile, it won't go into effect until each process exits and reloads its start up settings.

Look in /etc/ to modify the default start up variables for any particular shell. Just realize that users can (and often do) change them in their individual settings.

Unix is designed to obey the user, within limits.

NB: Bash is not the only shell on your system. Pay careful attention to what the /bin/sh symbolic link actually points to. On many systems, this could actually be dash which is (by default, with no special invocation) POSIXLY correct. Therefore, you should take care to modify both defaults, or scripts that start with /bin/sh will not inherit your global defaults. Similarly, take care to avoid syntax that only bash understands when editing both, aka avoiding bashisms.

Since there is no native way to do this ,Here is less intrusive solution i found (dont add any 'old' prototype methods):

var ListenerTracker=new function(){
    var is_active=false;
    // listener tracking datas
    var _elements_  =[];
    var _listeners_ =[];
    this.init=function(){
        if(!is_active){//avoid duplicate call
            intercep_events_listeners();
        }
        is_active=true;
    };
    // register individual element an returns its corresponding listeners
    var register_element=function(element){
        if(_elements_.indexOf(element)==-1){
            // NB : split by useCapture to make listener easier to find when removing
            var elt_listeners=[{/*useCapture=false*/},{/*useCapture=true*/}];
            _elements_.push(element);
            _listeners_.push(elt_listeners);
        }
        return _listeners_[_elements_.indexOf(element)];
    };
    var intercep_events_listeners = function(){
        // backup overrided methods
        var _super_={
            "addEventListener"      : HTMLElement.prototype.addEventListener,
            "removeEventListener"   : HTMLElement.prototype.removeEventListener
        };

        Element.prototype["addEventListener"]=function(type, listener, useCapture){
            var listeners=register_element(this);
            // add event before to avoid registering if an error is thrown
            _super_["addEventListener"].apply(this,arguments);
            // adapt to 'elt_listeners' index
            useCapture=useCapture?1:0;

            if(!listeners[useCapture][type])listeners[useCapture][type]=[];
            listeners[useCapture][type].push(listener);
        };
        Element.prototype["removeEventListener"]=function(type, listener, useCapture){
            var listeners=register_element(this);
            // add event before to avoid registering if an error is thrown
            _super_["removeEventListener"].apply(this,arguments);
            // adapt to 'elt_listeners' index
            useCapture=useCapture?1:0;
            if(!listeners[useCapture][type])return;
            var lid = listeners[useCapture][type].indexOf(listener);
            if(lid>-1)listeners[useCapture][type].splice(lid,1);
        };
        Element.prototype["getEventListeners"]=function(type){
            var listeners=register_element(this);
            // convert to listener datas list
            var result=[];
            for(var useCapture=0,list;list=listeners[useCapture];useCapture++){
                if(typeof(type)=="string"){// filtered by type
                    if(list[type]){
                        for(var id in list[type]){
                            result.push({"type":type,"listener":list[type][id],"useCapture":!!useCapture});
                        }
                    }
                }else{// all
                    for(var _type in list){
                        for(var id in list[_type]){
                            result.push({"type":_type,"listener":list[_type][id],"useCapture":!!useCapture});
                        }
                    }
                }
            }
            return result;
        };
    };
}();
ListenerTracker.init();

On Linux the command is whereis. Alternatively you can issue find / -name git and wait for an eternity. Alternatively try echo $PATH | sed "s/:/ /g" | xargs -L 1 ls | grep git

fwiw, for a conda env:

 conda install -c anaconda pymysql 

Take a look at this WPF metro-styled window with optional glowing borders.

This is a stand-alone application using no other libraries than Microsoft.Windows.Shell (included) to create metro-styled windows with optional glowing borders.

I suppose https://get-ytt.io/ would be an acceptable solution to your problem

If I understand correctly, you want only the error for the failing step to show, right?

That should be as simple as changing the failure case of the first promise to this:

step(1).then(function (response) {
    step(2);
}, function (response) {
    stepError(1);
    return response;
}).then( ... )

By returning $q.reject() in the first step's failure case, you're rejecting that promise, which causes the errorCallback to be called in the 2nd then(...).

I know you already accepted the other answer, but if you want to do this as a DataFrame, just use groupBy and agg. Assuming you had a DF already created (with columns named "col1", "col2", etc) you could do:

myDF.groupBy($"col1", $"col3", $"col4").agg($"col1", max($"col2"), $"col3", $"col4")

Note that in this case, I chose the Max of col2, but you could do avg, min, etc.

The code to calculate factorial depends on your requirements.

1. Are you concerned about overflow?
2. What range of inputs will you have?
3. Is it more important for you to minimize size or time?
4. What are you going to do with the factorial?

Regarding points 1 and 4, it is often more useful to have a function to evaluate the log of the factorial directly rather than to have a function to evaluate factorial itself.

Here's a blog post that discusses these issues. Here is some C# code for computing log factorial that would be trivial to port to JavaScript. But it may not be best for your needs depending on your answers to the questions above.

I had this problem while using a web framework and fixed it by moving the relevant javascript files into the designated (by the framework) javascript folder.

@VonC's answer to a duplicate question:

If, as commented, Paraminko does not support PPK key, the official solution, as seen here, would be to use PuTTYgen.

But you can also use the Python library CkSshKey to make that same conversion directly in your program.

See "Convert PuTTY Private Key (ppk) to OpenSSH (pem)"

import sys
import chilkat

key = chilkat.CkSshKey()

#  Load an unencrypted or encrypted PuTTY private key.

#  If  your PuTTY private key is encrypted, set the Password
#  property before calling FromPuttyPrivateKey.
#  If your PuTTY private key is not encrypted, it makes no diffference
#  if Password is set or not set.
key.put_Password("secret")

#  First load the .ppk file into a string:

keyStr = key.loadText("putty_private_key.ppk")

#  Import into the SSH key object:
success = key.FromPuttyPrivateKey(keyStr)
if (success != True):
    print(key.lastErrorText())
    sys.exit()

#  Convert to an encrypted or unencrypted OpenSSH key.

#  First demonstrate converting to an unencrypted OpenSSH key

bEncrypt = False
unencryptedKeyStr = key.toOpenSshPrivateKey(bEncrypt)
success = key.SaveText(unencryptedKeyStr,"unencrypted_openssh.pem")
if (success != True):
    print(key.lastErrorText())
    sys.exit()

Apologies in advance for this lo-tech suggestion, but another option, which finally worked for me after battling NuGet for several hours, is to re-create a new empty project, Web API in my case, and just copy the guts of your old, now-broken project into the new one. Took me about 15 minutes.

I'm not sure why the accepted answer was accepted if the suggested solution did not and does not solve the issue. There can actually be two related issues related to this topic.

Issue #1

The master page (e.g. _Layout.cshtml) has a section defined and it is required but the inheriting views did not implement it. For example,

The Layout Template

<body>
    @* Visible only to admin users *@
    <div id="option_box"> 
        @* this section is required due to the absence of the second parameter *@
        @RenderSection("OptionBox") 
    </div>
</body>

The Inheriting View

No need to show any code, just consider that there is no implementation of @section OptionBox {} on the view.

The Error for Issue #1

Section not defined: "OptionBox ".

Issue #2

The master page (e.g. _Layout.cshtml) has a section defined and it is required AND the inheriting view did implement it. However, the implementing view have additional script sections that are not defined on (any of) its master page(s).

The Layout Template

same as above

The Inheriting View

<div>
  <p>Looks like the Lakers can still make it to the playoffs</p>
</div>
@section OptionBox {
<a href"">Go and reserve playoff tickets now</a>
}
@section StatsBox {
<ul>
    <li>1. San Antonio</li>
    <li>8. L. A. Lakers</li>
</ul>
}

The Error for Issue #2

The following sections have been defined but have not been rendered for the layout page "~/Views/Shared/_Layout.cshtml": "StatsBox"

The OP's issue is similar to Issue #2 and the accepted answer is for Issue #1.

This can happen if you call

 .SingleOrDefault() 

on an IEnumerable with 2 or more elements.

If you d_o_ decide you truly need a full byte-by-byte comparison (see other answers for discussion of hashing), then the easiest solution is:

public static bool AreFileContentsEqual(String path1, String path2) =>
              File.ReadAllBytes(path1).SequenceEqual(File.ReadAllBytes(path2));

public static bool AreFileContentsEqual(FileInfo fi1, FileInfo fi2) =>
    fi1.Length == fi2.Length &&
    (fi1.Length == 0 || File.ReadAllBytes(fi1.FullName).SequenceEqual(
                        File.ReadAllBytes(fi2.FullName)));

Unlike some other posted answers, this is conclusively correct for any kind of file: binary, text, media, executable, etc., but as a full binary comparison, files that that differ only in "unimportant" ways (such as BOM, line-ending, character encoding, media metadata, whitespace, padding, source-code comments, etc.) will always be considered not-equal.

This code loads both files into memory entirely, so it should not be used for comparing truly gigantic files. Beyond that important caveat, full loading isn't really a penalty given the design of the .NET GC (because it's fundamentally optimized to keep small, short-lived allocations extremely cheap), and in fact could even be optimal when file sizes are expected to be less than 85K, because using a minimum of user code (as shown here) implies maximally delegating file performance issues to the CLR, BCL, and JIT to benefit from (e.g.) the latest design technology, system code, and adaptive runtime optimizations.

Furthermore, for such workaday scenarios, concerns about the performance of byte-by-byte comparison via LINQ enumerators (as shown here) are moot, since hitting the disk a_t_ a_l_l_ for file I/O will dwarf, by several orders of magnitude, the benefits of the various memory-comparing alternatives. For example, even though SequenceEqual does in fact give us the "optimization" of abandoning on first mismatch, this hardly matters after having already fetched the files' contents, each fully necessary to confirm the match.

$( ".nav li" ).click(function() {
        $('.nav li').removeClass('active');
        $(this).addClass('active');
    });

check this out.

Here's a simpler solution using what Akhil Sekharan has provided but with a little change.

var inputs = document.getElementsByTagName('input');

for (var i = 0; i < inputs.length; i += 1) {
if(parseInt(inputs[i].value)){
        inputs[i].value = '';
       }
    }????
document.getElementById('total').value = total;

no any libs are used:

dict_format_string = "{'1':'one', '2' : 'two'}"
d = {}
elems  = filter(str.isalnum,dict_format_string.split("'"))
values = elems[1::2]
keys   = elems[0::2]
d.update(zip(keys,values))

NOTE: As it has hardcoded split("'") will work only for strings where data is "single quoted".

You have to declare the array variable as an array:

Dim test(10) As Variant

Shouldn't you also be using the jspdf.plugin.from_html.js library? Besides the main library (jspdf.js), you must use other libraries for "special operations" (like jspdf.plugin.addimage.js for using images). Check https://github.com/MrRio/jsPDF.

$cols = sqlite_fetch_column_types('form name'$db, SQLITE_ASSOC);

}

The solution presented as an answer does not work, what is wrong?

In line with my answer to a related question, I'm going to disagree with BJ and suggest you first look at GCD over NSOperation / NSOperationQueue, unless the latter provides something you need that GCD doesn't.

Before GCD, I used a lot of NSOperations / NSOperationQueues within my applications for managing concurrency. However, since I started using GCD on a regular basis, I've almost entirely replaced NSOperations and NSOperationQueues with blocks and dispatch queues. This has come from how I've used both technologies in practice, and from the profiling I've performed on them.

First, there is a nontrivial amount of overhead when using NSOperations and NSOperationQueues. These are Cocoa objects, and they need to be allocated and deallocated. In an iOS application that I wrote which renders a 3-D scene at 60 FPS, I was using NSOperations to encapsulate each rendered frame. When I profiled this, the creation and teardown of these NSOperations was accounting for a significant portion of the CPU cycles in the running application, and was slowing things down. I replaced these with simple blocks and a GCD serial queue, and that overhead disappeared, leading to noticeably better rendering performance. This wasn't the only place where I noticed overhead from using NSOperations, and I've seen this on both Mac and iOS.

Second, there's an elegance to block-based dispatch code that is hard to match when using NSOperations. It's so incredibly convenient to wrap a few lines of code in a block and dispatch it to be performed on a serial or concurrent queue, where creating a custom NSOperation or NSInvocationOperation to do this requires a lot more supporting code. I know that you can use an NSBlockOperation, but you might as well be dispatching something to GCD then. Wrapping this code in blocks inline with related processing in your application leads in my opinion to better code organization than having separate methods or custom NSOperations which encapsulate these tasks.

NSOperations and NSOperationQueues still have very good uses. GCD has no real concept of dependencies, where NSOperationQueues can set up pretty complex dependency graphs. I use NSOperationQueues for this in a handful of cases.

Overall, while I usually advocate for using the highest level of abstraction that accomplishes the task, this is one case where I argue for the lower-level API of GCD. Among the iOS and Mac developers I've talked with about this, the vast majority choose to use GCD over NSOperations unless they are targeting OS versions without support for it (those before iOS 4.0 and Snow Leopard).

to get attribute from enum, i'm using :

 public enum ExceptionCodes
 {
  [ExceptionCode(1000)]
  InternalError,
 }

 public static (int code, string message) Translate(ExceptionCodes code)
        {
            return code.GetType()
            .GetField(Enum.GetName(typeof(ExceptionCodes), code))
            .GetCustomAttributes(false).Where((attr) =>
            {
                return (attr is ExceptionCodeAttribute);
            }).Select(customAttr =>
            {
                var attr = (customAttr as ExceptionCodeAttribute);
                return (attr.Code, attr.FriendlyMessage);
            }).FirstOrDefault();
        }

// Using

 var _message = Translate(code);

np.isnan combined with np.argwhere

x = np.array([[1,2,3,4],
              [2,3,np.nan,5],
              [np.nan,5,2,3]])
np.argwhere(np.isnan(x))

output:

array([[1, 2],
       [2, 0]])

A solution for those using Kotlin DSL

The solutions added so far are great for the OP, but can't be used with Kotlin DSL without first translating them. Here's an example of how I added a local .JAR to my build using Kotlin DSL:

dependencies {
    compile(files("/path/to/file.jar"))
    testCompile(files("/path/to/file.jar"))
    testCompile("junit", "junit", "4.12")
}

Remember that if you're using Windows, your backslashes will have to be escaped:

...
compile(files("C:\\path\\to\\file.jar"))
...

And also remember that quotation marks have to be double quotes, not single quotes.

Edit for 2020:

Gradle updates have deprecated compile and testCompile in favor of implementation and testImplementation. So the above dependency block would look like this for current Gradle versions:

dependencies {
    implementation(files("/path/to/file.jar"))
    testImplementation(files("/path/to/file.jar"))
    testImplementation("junit", "junit", "4.12")
}

svn cat takes a revision arg too!

svn cat -r 175 mydir/myfile > mydir/myfile

Spring abstracts you from the very very very large list of http status code. That is the idea of the exceptions. Take a look into org.springframework.web.client.RestClientException hierarchy:

You have a bunch of classes to map the most common situations when dealing with http responses. The http codes list is really large, you won't want write code to handle each situation. But for example, take a look into the HttpClientErrorException sub-hierarchy. You have a single exception to map any 4xx kind of error. If you need to go deep, then you can. But with just catching HttpClientErrorException, you can handle any situation where bad data was provided to the service.

The DefaultResponseErrorHandler is really simple and solid. If the response status code is not from the family of 2xx, it just returns true for the hasError method.

You simply need to make cab a string:

cab = '6176'

As the error message states, you cannot do <int> in <string>:

>>> 1 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>> 

because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").

In fact, Python only allows you to use the in operator with a right operand of type string if the left operand is also of type string:

>>> '1' in '123'  # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list
>>>
>>> 1.0 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not float
>>>
>>> {} in '123'
Traceback (most recent call last):

The && function is not vectorized. You need the & function:

EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]

Try using

<table  border="1" cellspacing="0" cellpadding="0" class="template-table" 
style="table-layout: fixed; width: 100%"> 

as table style along with

<td style="word-break:break-word">long text</td>

for td it works for normal/real scenario text with words, not for random typed letters without gaps

Try this:

    Dim x As Integer
    xrndom = New Random

    Dim yrndom As Random
    Dim y As Integer
    yrndom = New Random

This query should work very well on MySQL:

SELECT concat(left(curdate(),7),'-01') 

An one-liner that works with alternative libraries to jQuery:

$('p').filter((i, p) => $(p).text().trim() === "hello").css('font-weight', 'bold');

And this is the equivalent to a jQuery's a:contains("pattern") selector:

var res = $('a').filter((i, a) => $(a).text().match(/pattern/));

Replace

f = open(D\\python\\HW\\2_1 - Copy.cp,"r");

by

f = open("D:\\python\\HW\\2_1 - Copy.cp", "r")

1. File path needs to be a string (constant)
2. need colon in Windows file path
3. space after comma for better style
4. ; after statement is allowed but fugly.

What tutorial are you using?

Given that I just lost a day trying to figure this out and actually found a solution with the help of a coworker, I thought I should chime in.

We have a large code base and we have to deal with 2 branch heavily being modified at the same time. There is a main branch and a secondary branch if you which.

While I merge the secondary branch into the main branch, work continues in the main branch and by the time i'm done, I can't push my changes because they are incompatible.

I therefore need to "rebase" my "merge".

This is how we finally did it :

1) make note of the SHA. ex.: c4a924d458ea0629c0d694f1b9e9576a3ecf506b

git log -1

2) Create the proper history but this will break the merge.

git rebase -s ours --preserve-merges origin/master

3) make note of the SHA. ex.: 29dd8101d78

git log -1

4) Now reset to where you were before

git reset c4a924d458ea0629c0d694f1b9e9576a3ecf506b --hard

5) Now merge the current master into your working branch

git merge origin/master
git mergetool
git commit -m"correct files

6) Now that you have the right files, but the wrong history, get the right history on top of your change with :

git reset 29dd8101d78 --soft

7) And then --amend the results in your original merge commit

git commit --amend

Voila!

Drag image from your hard drive to Drawable folder in your project and in code use it like this:

ImageView image;

image = (ImageView) findViewById(R.id.yourimageviewid);
image.setImageResource(R.drawable.imagename);

If this server is visible to the outside world, It's worth checking if it's having lots of requests to connect from the outside world (i.e. people trying to break into it)

If you want to exclude all the standard properties of the window object and view application-specific globals, this will print them to the Chrome console:

{

    const standardGlobals = new Set(["window", "self", "document", "name", "location", "customElements", "history", "locationbar", "menubar", "personalbar", "scrollbars", "statusbar", "toolbar", "status", "closed", "frames", "length", "top", "opener", "parent", "frameElement", "navigator", "origin", "external", "screen", "innerWidth", "innerHeight", "scrollX", "pageXOffset", "scrollY", "pageYOffset", "visualViewport", "screenX", "screenY", "outerWidth", "outerHeight", "devicePixelRatio", "clientInformation", "screenLeft", "screenTop", "defaultStatus", "defaultstatus", "styleMedia", "onsearch", "isSecureContext", "performance", "onappinstalled", "onbeforeinstallprompt", "crypto", "indexedDB", "webkitStorageInfo", "sessionStorage", "localStorage", "onabort", "onblur", "oncancel", "oncanplay", "oncanplaythrough", "onchange", "onclick", "onclose", "oncontextmenu", "oncuechange", "ondblclick", "ondrag", "ondragend", "ondragenter", "ondragleave", "ondragover", "ondragstart", "ondrop", "ondurationchange", "onemptied", "onended", "onerror", "onfocus", "onformdata", "oninput", "oninvalid", "onkeydown", "onkeypress", "onkeyup", "onload", "onloadeddata", "onloadedmetadata", "onloadstart", "onmousedown", "onmouseenter", "onmouseleave", "onmousemove", "onmouseout", "onmouseover", "onmouseup", "onmousewheel", "onpause", "onplay", "onplaying", "onprogress", "onratechange", "onreset", "onresize", "onscroll", "onseeked", "onseeking", "onselect", "onstalled", "onsubmit", "onsuspend", "ontimeupdate", "ontoggle", "onvolumechange", "onwaiting", "onwebkitanimationend", "onwebkitanimationiteration", "onwebkitanimationstart", "onwebkittransitionend", "onwheel", "onauxclick", "ongotpointercapture", "onlostpointercapture", "onpointerdown", "onpointermove", "onpointerup", "onpointercancel", "onpointerover", "onpointerout", "onpointerenter", "onpointerleave", "onselectstart", "onselectionchange", "onanimationend", "onanimationiteration", "onanimationstart", "ontransitionrun", "ontransitionstart", "ontransitionend", "ontransitioncancel", "onafterprint", "onbeforeprint", "onbeforeunload", "onhashchange", "onlanguagechange", "onmessage", "onmessageerror", "onoffline", "ononline", "onpagehide", "onpageshow", "onpopstate", "onrejectionhandled", "onstorage", "onunhandledrejection", "onunload", "alert", "atob", "blur", "btoa", "cancelAnimationFrame", "cancelIdleCallback", "captureEvents", "clearInterval", "clearTimeout", "close", "confirm", "createImageBitmap", "fetch", "find", "focus", "getComputedStyle", "getSelection", "matchMedia", "moveBy", "moveTo", "open", "postMessage", "print", "prompt", "queueMicrotask", "releaseEvents", "requestAnimationFrame", "requestIdleCallback", "resizeBy", "resizeTo", "scroll", "scrollBy", "scrollTo", "setInterval", "setTimeout", "stop", "webkitCancelAnimationFrame", "webkitRequestAnimationFrame", "chrome", "caches", "ondevicemotion", "ondeviceorientation", "ondeviceorientationabsolute", "originAgentCluster", "cookieStore", "showDirectoryPicker", "showOpenFilePicker", "showSaveFilePicker", "speechSynthesis", "onpointerrawupdate", "trustedTypes", "crossOriginIsolated", "openDatabase", "webkitRequestFileSystem", "webkitResolveLocalFileSystemURL"]);

    for (const key of Object.keys(window)) {
        if (!standardGlobals.has(key)) {
            console.log(key)
        }
    }
}

The script works well as a bookmarklet. To use the script as a bookmarklet, create a new bookmark and replace the URL with the following:

javascript:(() => {
    const standardGlobals = new Set(["window", "self", "document", "name", "location", "customElements", "history", "locationbar", "menubar", "personalbar", "scrollbars", "statusbar", "toolbar", "status", "closed", "frames", "length", "top", "opener", "parent", "frameElement", "navigator", "origin", "external", "screen", "innerWidth", "innerHeight", "scrollX", "pageXOffset", "scrollY", "pageYOffset", "visualViewport", "screenX", "screenY", "outerWidth", "outerHeight", "devicePixelRatio", "clientInformation", "screenLeft", "screenTop", "defaultStatus", "defaultstatus", "styleMedia", "onsearch", "isSecureContext", "performance", "onappinstalled", "onbeforeinstallprompt", "crypto", "indexedDB", "webkitStorageInfo", "sessionStorage", "localStorage", "onabort", "onblur", "oncancel", "oncanplay", "oncanplaythrough", "onchange", "onclick", "onclose", "oncontextmenu", "oncuechange", "ondblclick", "ondrag", "ondragend", "ondragenter", "ondragleave", "ondragover", "ondragstart", "ondrop", "ondurationchange", "onemptied", "onended", "onerror", "onfocus", "onformdata", "oninput", "oninvalid", "onkeydown", "onkeypress", "onkeyup", "onload", "onloadeddata", "onloadedmetadata", "onloadstart", "onmousedown", "onmouseenter", "onmouseleave", "onmousemove", "onmouseout", "onmouseover", "onmouseup", "onmousewheel", "onpause", "onplay", "onplaying", "onprogress", "onratechange", "onreset", "onresize", "onscroll", "onseeked", "onseeking", "onselect", "onstalled", "onsubmit", "onsuspend", "ontimeupdate", "ontoggle", "onvolumechange", "onwaiting", "onwebkitanimationend", "onwebkitanimationiteration", "onwebkitanimationstart", "onwebkittransitionend", "onwheel", "onauxclick", "ongotpointercapture", "onlostpointercapture", "onpointerdown", "onpointermove", "onpointerup", "onpointercancel", "onpointerover", "onpointerout", "onpointerenter", "onpointerleave", "onselectstart", "onselectionchange", "onanimationend", "onanimationiteration", "onanimationstart", "ontransitionrun", "ontransitionstart", "ontransitionend", "ontransitioncancel", "onafterprint", "onbeforeprint", "onbeforeunload", "onhashchange", "onlanguagechange", "onmessage", "onmessageerror", "onoffline", "ononline", "onpagehide", "onpageshow", "onpopstate", "onrejectionhandled", "onstorage", "onunhandledrejection", "onunload", "alert", "atob", "blur", "btoa", "cancelAnimationFrame", "cancelIdleCallback", "captureEvents", "clearInterval", "clearTimeout", "close", "confirm", "createImageBitmap", "fetch", "find", "focus", "getComputedStyle", "getSelection", "matchMedia", "moveBy", "moveTo", "open", "postMessage", "print", "prompt", "queueMicrotask", "releaseEvents", "requestAnimationFrame", "requestIdleCallback", "resizeBy", "resizeTo", "scroll", "scrollBy", "scrollTo", "setInterval", "setTimeout", "stop", "webkitCancelAnimationFrame", "webkitRequestAnimationFrame", "chrome", "caches", "ondevicemotion", "ondeviceorientation", "ondeviceorientationabsolute", "originAgentCluster", "cookieStore", "showDirectoryPicker", "showOpenFilePicker", "showSaveFilePicker", "speechSynthesis", "onpointerrawupdate", "trustedTypes", "crossOriginIsolated", "openDatabase", "webkitRequestFileSystem", "webkitResolveLocalFileSystemURL"]);
    for (const key of Object.keys(window)) {
        if (!standardGlobals.has(key)) {
            console.log(key)
        }
    }
})()

I had the same problem before and I got the solution for it.

I just added the libraries that had the another version but with the same version of my support:appcompat.

For your error for example :

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and com.android.support:mediarouter-v7:24.0.0

*The solution is to compile the versions of these libraries like that :

compile 'com.android.support:mediarouter-v7:25.1.1'

-if another library had the same issue and had another version just compile it with your support:appcompat version

This resolved my problem and I hope it resolves yours.

Best wishes :)

After checking the permission of the folder, it is okay with 744. I had the problem with a plugin that is installed on my WordPress site. The plugin has hooked that are in the corn job I suspected.

With a simple sudo it can fix the issue

sudo git pull origin master

You have it working.

Use the DATEDIFF function with a datepart of day.

SELECT ...
FROM ...
WHERE DATEDIFF(day, date1, date2) >= 0

Note that if you want to test that date1 <= date2 then you need to test that DATEDIFF(day, date1, date2) >= 0, or alternatively you could test DATEDIFF(day, date2, date1) <= 0.

This will do it:

while d:
    k, v = d.popitem()
    # now use k and v ...

A dictionary in boolean context is False if empty, True otherwise.

There is no "first" item in a dictionary, because dictionaries aren't ordered. But popitem will remove and return some item for you each time.

This isn’t a solution in the sense that it doesn’t resolve the conditions which cause the message to appear in the logs, but the message can be suppressed by appending the following to conf/logging.properties:

org.apache.catalina.webresources.Cache.level = SEVERE

This filters out the “Unable to add the resource” logs, which are at level WARNING.

In my view a WARNING is not necessarily an error that needs to be addressed, but rather can be ignored if desired.

I found that:

git log --reverse

shows commits from start.

Try to run this code:

del x[:N]

If you a running Jupyter/Ipython notebook and having problems using;

ax = df1.plot()

df2.plot(ax=ax)

Run the command inside of the same cell!! It wont, for some reason, work when they are separated into sequential cells. For me at least.

I profiled a few methods to move an item within the same list with timeit. Here are the ones to use if j>i:

+---------------------------------+
¦ 14.4usec ¦ x[i:i]=x.pop(j),     ¦
¦ 14.5usec ¦ x[i:i]=[x.pop(j)]    ¦
¦ 15.2usec ¦ x.insert(i,x.pop(j)) ¦
+---------------------------------+

and here the ones to use if j<=i:

+--------------------------------------+
¦ 14.4usec ¦ x[i:i]=x[j],;del x[j]     ¦
¦ 14.4usec ¦ x[i:i]=[x[j]];del x[j]    ¦
¦ 15.4usec ¦ x.insert(i,x[j]);del x[j] ¦
+--------------------------------------+

Not a huge difference if you only use it a few times, but if you do heavy stuff like manual sorting, it's important to take the fastest one. Otherwise, I'd recommend just taking the one that you think is most readable.

For a more complete answer: http://www.compulsivecoders.com/tech/vuejs-component-template-should-contain-exactly-one-root-element/

But basically:

• Currently, a VueJS template can contain only one root element (because of rendering issue)
• In cases you really need to have two root elements because HTML structure does not allow you to create a wrapping parent element, you can use vue-fragment.

To install it:

npm install vue-fragment

To use it:

import Fragment from 'vue-fragment';
Vue.use(Fragment.Plugin);

// or

import { Plugin } from 'vue-fragment';
Vue.use(Plugin);

Then, in your component:

<template>
  <fragment>
    <tr class="hola">
      ...
    </tr>
    <tr class="hello">
      ...
    </tr>
  </fragment>
</template>

This can be a quick hack to connect hive and python,

from pyhive import hive
cursor = hive.connect('YOUR_HOST_NAME').cursor()
cursor.execute('SELECT * from table_name LIMIT 5',async=True)
print cursor.fetchall()

Output: List of Tuples

All solutions given thus far only account for a once off resize. You mention you want to be able to resize the iFrame after the contents are modified. In order to do this, you need to execute a function inside the iFrame (once the contents are changed, you need to fire an event to say that the contents have changed).

I was stuck with this for a while, as code inside the iFrame seemed limited to the DOM inside the iFrame (and couldn't edit the iFrame), and code executed outside the iFrame was stuck with the DOM outside the iFrame (and couldn't pick up an event coming from inside the iFrame).

The solution came from discovering (via assistance from a colleague) that jQuery can be told what DOM to use. In this case, the DOM of the parent window.

As such, code such as this does what you need (when run inside the iFrame) :

<script type="text/javascript">
    jQuery(document).ready(function () {
        jQuery("#IDofControlFiringResizeEvent").click(function () {
            var frame = $('#IDofiframeInMainWindow', window.parent.document);
            var height = jQuery("#IDofContainerInsideiFrame").height();
            frame.height(height + 15);
        });
    });
</script>

The align-items, or respectively align-content attribute controls this behaviour.

align-items defines the items' positioning perpendicularly to flex-direction.

The default flex-direction is row, therfore vertical placement can be controlled with align-items.

There is also the align-self attribute to control the alignment on a per item basis.

#a {_x000D_
  display:flex;_x000D_
_x000D_
  align-items:flex-start;_x000D_
  align-content:flex-start;_x000D_
  }_x000D_
_x000D_
#a > div {_x000D_
  _x000D_
  background-color:red;_x000D_
  padding:5px;_x000D_
  margin:2px;_x000D_
  }_x000D_
 #a > #c {_x000D_
  align-self:stretch;_x000D_
 }

<div id="a">_x000D_
  _x000D_
  <div id="b">left</div>_x000D_
  <div id="c">middle</div>_x000D_
  <div>right<br>right<br>right<br>right<br>right<br></div>_x000D_
  _x000D_
</div>

If none of the other comments works, just do, open console line command and type:

document.oncontextmenu = null;

You can try

iris %>% select(-!!drop.cols)

Depending on your application, you'll probably want to use that Font assignment either on text change or focus/unfocus of the textbox in question.

Here's a quick sample of what it could look like (empty form, with just a textbox. Font turns bold when the text reads 'bold', case-insensitive):

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

    private void RegisterEvents()
    {
        _tboTest.TextChanged += new EventHandler(TboTest_TextChanged);
    }

    private void TboTest_TextChanged(object sender, EventArgs e)
    {
        // Change the text to bold on specified condition
        if (_tboTest.Text.Equals("Bold", StringComparison.OrdinalIgnoreCase))
        {
            _tboTest.Font = new Font(_tboTest.Font, FontStyle.Bold);
        }
        else
        {
            _tboTest.Font = new Font(_tboTest.Font, FontStyle.Regular);
        }
    }
}

Any how myMethod() should return a String value .what if your condition is false is myMethod return anything? ans is no so you need to define return null or some string value in false condition

public String myMethod() {
    boolean c=true;
    if (conditions) {
        return "d";
    }
    return null;//or some other string value
}

As well as find listed in other answers, better shells allow both recurvsive globs and filtering of glob matches, so in zsh for example...

ls -lad **/*(/)

...lists all directories while keeping all the "-l" details that you want, which you'd otherwise need to recreate using something like...

find . -type d -exec ls -ld {} \;

(not quite as easy as the other answers suggest)

The benefit of find is that it's more independent of the shell - more portable, even for system() calls from within a C/C++ program etc..

I believe the default color integer value is 16711935 (0x00FF00FF).

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

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

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

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

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

If you don't want to use any java predefined libraries then below is the

simplest way

   public class Test {

    public static void main(String[] args) {
        double[] decMax = {-2.8, -8.8, 2.3, 7.9, 4.1, -1.4, 11.3, 10.4,
            8.9, 8.1, 5.8, 5.9, 7.8, 4.9, 5.7, -0.9, -0.4, 7.3, 8.3, 6.5, 9.2,
            3.5, 3, 1.1, 6.5, 5.1, -1.2, -5.1, 2, 5.2, 2.1};

        double maxx = decMax[0];

        for (int i = 0; i < decMax.length; i++) {
            if (maxx < decMax[i]) {
                maxx = decMax[i];
            }
        }
        System.out.println(maxx);

    }
}

fill_parent :

A component is arranged layout for the fill_parent will be mandatory to expand to fill the layout unit members, as much as possible in the space. This is consistent with the dockstyle property of the Windows control. A top set layout or control to fill_parent will force it to take up the entire screen.

wrap_content

Set up a view of the size of wrap_content will be forced to view is expanded to show all the content. The TextView and ImageView controls, for example, is set to wrap_content will display its entire internal text and image. Layout elements will change the size according to the content. Set up a view of the size of Autosize attribute wrap_content roughly equivalent to set a Windows control for True.

If your database is small enough (or if you add enough memory) your database will effectively run in memory since it your data will be cached after the first request.

Changing the database table definitions to use the memory engine is probably more complicated than you need.

If you have enough memory to load the tables into memory with the MEMORY engine, you have enough to tune the innodb settings to cache everything anyway.

The clean, install and deploy phases are valid lifecycle phases and invoking them will trigger all the phases preceding them, and the goals bound to these phases.

mvn clean install

This command invokes the clean phase and then the install phase sequentially:

• clean: removes files generated at build-time in a project's directory (target by default)
• install: installs the package into the local repository, for use as a dependency in other projects locally.

mvn deploy

This command invokes the deploy phase:

• deploy: copies the final package to the remote repository for sharing with other developers and projects.

mvn release

This is not a valid phase nor a goal so this won't do anything. But if refers to the Maven Release Plugin that is used to automate release management. Releasing a project is done in two steps: prepare and perform. As documented:

Preparing a release goes through the following release phases:

• Check that there are no uncommitted changes in the sources
• Check that there are no SNAPSHOT dependencies
• Change the version in the POMs from x-SNAPSHOT to a new version (you will be prompted for the versions to use)
• Transform the SCM information in the POM to include the final destination of the tag
• Run the project tests against the modified POMs to confirm everything is in working order
• Commit the modified POMs
• Tag the code in the SCM with a version name (this will be prompted for)
• Bump the version in the POMs to a new value y-SNAPSHOT (these values will also be prompted for)
• Commit the modified POMs

And then:

Performing a release runs the following release phases:

• Checkout from an SCM URL with optional tag
• Run the predefined Maven goals to release the project (by default, deploy site-deploy)

I don't like the proposed solution of using web.config or app.config. Try reading your own XML. Have a look at XML Settings Files – No more web.config.

Difference between pointer and reference

A pointer can be initialized to 0 and a reference not. In fact, a reference must also refer to an object, but a pointer can be the null pointer:

int* p = 0;

But we can’t have int& p = 0; and also int& p=5 ;.

In fact to do it properly, we must have declared and defined an object at the first then we can make a reference to that object, so the correct implementation of the previous code will be:

Int x = 0;
Int y = 5;
Int& p = x;
Int& p1 = y;

Another important point is that is we can make the declaration of the pointer without initialization however no such thing can be done in case of reference which must make a reference always to variable or object. However such use of a pointer is risky so generally we check if the pointer is actually is pointing to something or not. In case of a reference no such check is necessary, because we know already that referencing to an object during declaration is mandatory.

Another difference is that pointer can point to another object however reference is always referencing to the same object, let’s take this example:

Int a = 6, b = 5;
Int& rf = a;

Cout << rf << endl; // The result we will get is 6, because rf is referencing to the value of a.

rf = b;
cout << a << endl; // The result will be 5 because the value of b now will be stored into the address of a so the former value of a will be erased

Another point: When we have a template like an STL template such kind of a class template will always return a reference, not a pointer, to make easy reading or assigning new value using operator []:

Std ::vector<int>v(10); // Initialize a vector with 10 elements
V[5] = 5; // Writing the value 5 into the 6 element of our vector, so if the returned type of operator [] was a pointer and not a reference we should write this *v[5]=5, by making a reference we overwrite the element by using the assignment "="

Something like that should do the job

for root, dirs, files in os.walk(directory):
    for file in files:
        if file.endswith('.txt'):
            print file

For me it only worked when I set the permission on the phone itself (settings -> app permissions -> location always on).

Something new to think about looking forward to Object.observe in ES7 and with data-binding in general. Consider:

var foo={
   name: "hello"
};

Object.observe(foo, function(){alert('modified');}); // bind to foo

foo={}; // You are no longer bound to foo but to an orphaned version of it
foo.name="there"; // This change will be missed by Object.observe()

So under that circumstance #2 can be the best choice.

try this

Execute this SQL:

SHOW TABLE STATUS LIKE '<tablename>'

and fetch the value of the field Auto_increment

I had a dynamically generated, but badly formed table with a typo. I copied a <td> tag inside another <td> by mistake. My column count matched. I had <thead> and <tbody> tags. Everything matched, except for this little mistake I didn't notice for a while, because my column had a lot of link and image tags in it.

thisReader.GetString(int columnIndex)

Only with 1 line of CSS… You can get this done.

body{ height: 100vh; }

A better(error-free) code would be like:

function isReallyNumber(data) {
    return typeof data === 'number' && !isNaN(data);
}

This will handle empty strings as well. Another reason, isNaN("12") equals to false but "12" is a string and not a number, so it should result to true. Lastly, a bonus link which might interest you.

MySQL server 5.7 was already installed by default on my new Linux Mint 19.

But, what's the MySQL root password? It turns out that:

The default installation uses auth_socket for authentication, in lieu of passwords!

It allows a password-free login, provided that one is logged into the Linux system with the same user name. To login as the MySQL root user, one can use sudo:

sudo mysql --user=root

But how to then change the root password? To illustrate what's going on, I created a new user "me", with full privileges, with:

mysql> CREATE USER 'me'@'localhost' IDENTIFIED BY 'my_new_password';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'me'@'localhost' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;

Comparing "me" with "root":

mysql> SELECT user, plugin, HEX(authentication_string)  FROM mysql.user WHERE user = 'me' or user = 'root';
+------+-----------------------+----------------------------------------------------------------------------+
| user | plugin                | HEX(authentication_string)                                                 |
+------+-----------------------+----------------------------------------------------------------------------+
| root | auth_socket           |                                                                            |
| me   | mysql_native_password | 2A393846353030304545453239394634323734333139354241344642413245373537313... |
+------+-----------------------+----------------------------------------------------------------------------+

Because it's using auth_socket, the root password cannot be changed: the SET PASSWORD command fails, and mysql_secure_installation desn't attain anything...

==> To zap this alternate authentication mode and return the MySQL root user to using passwords:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'SOME_NEW_ROOT_PASSWORD';

A good explanation.

More details from the MySQL manual.

I would suggest instead of creating a new table, you just use a view that combines the two tables, this way if any of the data in table 1 or table 2 changes, you don't need to update the third table:

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t1.ID, t2.Number
    FROM    Table1 t1
            INNER JOIN Table2 t2
                ON t1.ID = t2.ID;

If you could have records in one table, and not in the other, then you would need to use a full join:

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, ID = ISNULL(t1.ID, t2.ID), t2.Number
    FROM    Table1 t1
            FULL JOIN Table2 t2
                ON t1.ID = t2.ID;

If you know all records will be in table 1 and only some in table 2, then you should use a LEFT JOIN:

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t1.ID, t2.Number
    FROM    Table1 t1
            LEFT JOIN Table2 t2
                ON t1.ID = t2.ID;

If you know all records will be in table 2 and only some in table 2 then you could use a RIGHT JOIN

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t2.ID, t2.Number
    FROM    Table1 t1
            RIGHT JOIN Table2 t2
                ON t1.ID = t2.ID;

Or just reverse the order of the tables and use a LEFT JOIN (I find this more logical than a right join but it is personal preference):

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t2.ID, t2.Number
    FROM    Table2 t2
            LEFT JOIN Table1 t1
                ON t1.ID = t2.ID;

Set background to null.

android:background="@null"

To replace a string in a single file (currently opened): CTRL + H

For replacing at workspace level use: CTRL + SHIFT + H

Outline: Create two elements: a slider/switch and a trough as a parent of the slider. To toggle the state, switch the slider element between an "on" and an "off" class. In the style for one class, set "left" to 0 and leave "right" the default; for the other class, do the opposite:

<style type="text/css">
.toggleSwitch {
    width: ...;
    height: ...;
    /* add other styling as appropriate to position element */
    position: relative;
}
.slider {
    background-image: url(...);
    position: absolute;
    width: ...;
    height: ...;
}
.slider.on {
    right: 0;
}
.slider.off {
    left: 0;
}
</style>
<script type="text/javascript">
function replaceClass(elt, oldClass, newClass) {
    var oldRE = RegExp('\\b'+oldClass+'\\b');
    elt.className = elt.className.replace(oldRE, newClass);
}
function toggle(elt, on, off) {
    var onRE = RegExp('\\b'+on+'\\b');
    if (onRE.test(elt.className)) {
        elt.className = elt.className.replace(onRE, off);
    } else {
        replaceClass(elt, off, on);
    }
}
</script>
...
<div class="toggleSwitch" onclick="toggle(this.firstChild, 'on', 'off');"><div class="slider off" /></div>

Alternatively, just set the background image for the "on" and "off" states, which is a much easier approach than mucking about with positioning.

@Logan said it perfectly. but i would like to add an alternative here,

if you want to view logs from just your application then you can make a custom method that keeps saving the log to a file in documents directory & then you can view that log file from your application.

There is one good advantage for developers of the app after the app has been released & users are downloading it. Because your app will be able to send logs & crash reports to the developers (of course with the permissions of the device user !!!) & it'll be the way to improve your application.

Let me know (To other SO users), if there is another way of doing the same thing. (Like default Apple feature or something)

Let me know if it helps or you want some more idea.

You can use the length() method on File which returns the size in bytes.

Best Approach

App.getRes().getString(R.string.some_id)

Will work Everywhere (Utils, Models also).

I have read all the answers, all answers can make your work done.

• You can use getString(R.string.some_string_id) in both Activity or Fragment.
• You can use Context.getString(R.string.some_string_id) where you don't have direct access to getString() method. Like Dialog.

Problem

When you don't have Context access, like a method in your Util class.

Assume below method without Context.

public void someMethod(){
    ...
    // can't use getResource() or getString() without Context.
}

Now you will pass Context as a parameter in this method and use getString().

public void someMethod(Context context){
    ...
    context.getString(R.string.some_id);
}

What i do is

public void someMethod(){
    ...
    App.getAppResources().getString(R.string.some_id)
}

What? It is very simple to use anywhere in your app!

So here is a solution by which you can access resources from anywhere like Util class .

import android.app.Application;
import android.content.res.Resources;

public class App extends Application {
    private static Resources resources;

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

        resources = getResources();
    }

    public static Resources getAppResources() {
        return resources;
    }

}

Add name field to your manifest.xml <application tag.

<application
        android:name=".App"
        ...
        >
        ...
    </application>

Now you are good to go. Use App.getAppResources().getString(R.string.some_id) anywhere in app.

All the answers here seem to forget about landscape possibilities. If you would like this to work when the device is rotated to a landscape view, then you will face problems.

The trick here is that although the view is aware of the orientation, the keyboard is not. This means in Landscape, the keyboards width is actually its height and visa versa.

To modify Apples recommended way of changing the content insets and get it support landscape orientation, I would recommend using the following:

// Call this method somewhere in your view controller setup code.
- (void)registerForKeyboardNotifications
{
    [[NSNotificationCenter defaultCenter] addObserver:self
            selector:@selector(keyboardWasShown:)
            name:UIKeyboardDidShowNotification object:nil];
   [[NSNotificationCenter defaultCenter] addObserver:self
             selector:@selector(keyboardWillBeHidden:)
             name:UIKeyboardWillHideNotification object:nil];
}

// Called when the UIKeyboardDidShowNotification is sent.
- (void)keyboardWasShown:(NSNotification*)aNotification
{
    UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
    CGSize keyboardSize = [[[notif userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    if (orientation == UIDeviceOrientationLandscapeLeft || orientation == UIDeviceOrientationLandscapeRight ) {
        CGSize origKeySize = keyboardSize;
        keyboardSize.height = origKeySize.width;
        keyboardSize.width = origKeySize.height;
    }
    UIEdgeInsets contentInsets = UIEdgeInsetsMake(0, 0, keyboardSize.height, 0);
    scroller.contentInset = contentInsets;
    scroller.scrollIndicatorInsets = contentInsets;

    // If active text field is hidden by keyboard, scroll it so it's visible
    // Your application might not need or want this behavior.
    CGRect rect = scroller.frame;
    rect.size.height -= keyboardSize.height;
    NSLog(@"Rect Size Height: %f", rect.size.height);

    if (!CGRectContainsPoint(rect, activeField.frame.origin)) {
        CGPoint point = CGPointMake(0, activeField.frame.origin.y - keyboardSize.height);
        NSLog(@"Point Height: %f", point.y);
        [scroller setContentOffset:point animated:YES];
    }
}

// Called when the UIKeyboardWillHideNotification is sent    
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
    UIEdgeInsets contentInsets = UIEdgeInsetsZero;
    scrollView.contentInset = contentInsets;
    scrollView.scrollIndicatorInsets = contentInsets;
}

The part to pay attention to here is the following:

UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
CGSize keyboardSize = [[[notif userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
if (orientation == UIDeviceOrientationLandscapeLeft || orientation == UIDeviceOrientationLandscapeRight ) {
    CGSize origKeySize = keyboardSize;
    keyboardSize.height = origKeySize.width;
    keyboardSize.width = origKeySize.height;
}

What is does, is detects what orientation the device is in. If it is landscape, it will 'swap' the width and height values of the keyboardSize variable to ensure that the correct values are being used in each orientation.

Between 3-50 characters. Can contain lowercase letters, numbers and special characters - dot(.), dash(-), underscore(_) and at the rate(@).

Here's a non-CSS method. Using JQuery, simply remove the "focus" class whenever the element is has been clicked.

$(".btn").mousemove(function(element) { $(this).removeClass("focus"); });

This method may cause the border to flash into existence and then back out briefly, which doesn't look bad in my opinion (it looks like part of the response when the button is clicked).

The reason I used .mousemove() is that .click() and .mouseup() both proved to be ineffective.

I think the OP is asking how to swap a VIEW without changing viewCONTROLLERs. Am I misunderstanding his question?

In pseudocode, he wants to do:

let myController = instantiate(someParentController)

let view1 = Bundle.main.loadNib(....) as... blah
myController.setThisViewTo( view1 )

let view2 = Bundle.main.loadNib(....) as... blah
myController.setThisViewTo( view2 )

Am I getting his question wrong?

Try this code to watch for, and report, a possible net::ERR_INSECURE_RESPONSE

I was having this issue as well, using a self-signed certificate, which I have chosen not to save into the Chrome Settings. After accessing the https domain and accepting the certificate, the ajax call works fine. But once that acceptance has timed-out or before it has first been accepted, the jQuery.ajax() call fails silently: the timeout parameter does not seem help and the error() function never gets called.

As such, my code never receives a success() or error() call and therefore hangs. I believe this is a bug in jquery's handling of this error. My solution is to force the error() call after a specified timeout.

This code does assume a jquery ajax call of the form jQuery.ajax({url: required, success: optional, error: optional, others_ajax_params: optional}).

Note: You will likely want to change the function within the setTimeout to integrate best with your UI: rather than calling alert().

const MS_FOR_HTTPS_FAILURE = 5000;
$.orig_ajax = $.ajax;
$.ajax = function(params)
{
  var complete = false;
  var success = params.success;
  var error = params.error;
  params.success = function() {
    if(!complete) {
      complete = true;
      if(success) success.apply(this,arguments);
    }
  }
  params.error = function() {
    if(!complete) {
      complete = true;
      if(error) error.apply(this,arguments);
    }
  }
  setTimeout(function() {
    if(!complete) {
      complete = true;
      alert("Please ensure your self-signed HTTPS certificate has been accepted. "
        + params.url);
      if(params.error)
        params.error( {},
          "Connection failure",
          "Timed out while waiting to connect to remote resource. " +
          "Possibly could not authenticate HTTPS certificate." );
    }
  }, MS_FOR_HTTPS_FAILURE);

  $.orig_ajax(params);
}

Basic difference:

Factory: Creates objects without exposing the instantiation logic to the client.

Factory Method: Define an interface for creating an object, but let the subclasses decide which class to instantiate. The Factory method lets a class defer instantiation to subclasses

Abstract Factory: Provides an interface for creating families of related or dependent objects without specifying their concrete classes.

AbstractFactory pattern uses composition to delegate responsibility of creating object to another class while Factory method pattern uses inheritance and relies on derived class or sub class to create object

From oodesign articles:

Factory class diagram:

Example: StaticFactory

 public class ShapeFactory {

   //use getShape method to get object of type shape 
   public static Shape getShape(String shapeType){
      if(shapeType == null){
         return null;
      }     
      if(shapeType.equalsIgnoreCase("CIRCLE")){
         return new Circle();

      } else if(shapeType.equalsIgnoreCase("RECTANGLE")){
         return new Rectangle();

      } else if(shapeType.equalsIgnoreCase("SQUARE")){
         return new Square();
      }

      return null;
   }
}

Non-Static Factory implementing FactoryMethod example is available in this post:

Design Patterns: Factory vs Factory method vs Abstract Factory

When to use: Client just need a class and does not care about which concrete implementation it is getting.

Factory Method class digaram:

When to use: Client doesn't know what concrete classes it will be required to create at runtime, but just wants to get a class that will do the job.

Abstract Factory class diagram from dzone

When to use: When your system has to create multiple families of products or you want to provide a library of products without exposing the implementation details.

Source code examples in above articles are very good to understand the concepts clearly.

Related SE question with code example:

Factory Pattern. When to use factory methods?

Differences:

1. Abstract Factory classes are often implemented with Factory Methods, but they can also be implemented using Prototype
2. Designs start out using Factory Method (less complicated, more customizable, subclasses proliferate) and evolve toward other creational patterns (more flexible, more complex) where more flexibility is needed.
3. Factory Methods are usually called within Template Methods.

Regular Expressions (abbreviated "regex" or "reg-ex") is a string that defines a search pattern.

What replaceFirst() does is it uses the regular expression provided in the parameters and replaces the first result from the search with whatever you pass in as the other parameter.

What you want to do is convert the string to an array using the String class' charAt() method, and then use Character.toUpperCase() to change the character to upper case (obviously). Your code would look like this:

char first = Character.toUpperCase(userIdea.charAt(0));
betterIdea = first + userIdea.substring(1);

Or, if you feel comfortable with more complex, one-lined java code:

betterIdea = Character.toUpperCase(userIdea.charAt(0)) + userIdea.substring(1);

Both of these do the same thing, which is converting the first character of userIdea to an upper case character.

Instead of using position:relative in #icons, you could just take that away and maybe add a z-index or something so the picture won't get covered up. Hope this helps.

The short answer is yes, every implementing type will have to create its own backing variable. This is because an interface is analogous to a contract. All it can do is specify particular publicly accessible pieces of code that an implementing type must make available; it cannot contain any code itself.

Consider this scenario using what you suggest:

public interface InterfaceOne
{
    int myBackingVariable;

    int MyProperty { get { return myBackingVariable; } }
}

public interface InterfaceTwo
{
    int myBackingVariable;

    int MyProperty { get { return myBackingVariable; } }
}

public class MyClass : InterfaceOne, InterfaceTwo { }

We have a couple of problems here:

• Because all members of an interface are--by definition--public, our backing variable is now exposed to anyone using the interface
• Which myBackingVariable will MyClass use?

The most common approach taken is to declare the interface and a barebones abstract class that implements it. This allows you the flexibility of either inheriting from the abstract class and getting the implementation for free, or explicitly implementing the interface and being allowed to inherit from another class. It works something like this:

public interface IMyInterface
{
    int MyProperty { get; set; }
}

public abstract class MyInterfaceBase : IMyInterface
{
    int myProperty;

    public int MyProperty
    {
        get { return myProperty; }
        set { myProperty = value; }
    }
}

Since the accepted BufferedInputStream#read isn't guaranteed to read everything, rather than keeping track of the buffer sizes myself, I used this approach:

    byte bytes[] = new byte[(int) file.length()];
    BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file));
    DataInputStream dis = new DataInputStream(bis);
    dis.readFully(bytes);

Blocks until a full read is complete, and doesn't require extra imports.

I got this error in express/nodejs app, when the schema of MongoDB database and the models which we have created don't match.

Scrum is a very specific set of practices. Agile describes a family of practices, everything from Extreme Programming to Scrum and almost anything else that uses short iterations can claim Agile. That may not have originally been the case when the term was coined, but it certainly is by now.

Maybe (from git commit man page):

git commit --no-verify

-n  
--no-verify

This option bypasses the pre-commit and commit-msg hooks. See also githooks(5).

As commented by Blaise, -n can have a different role for certain commands.
For instance, git push -n is actually a dry-run push.
Only git push --no-verify would skip the hook.

Note: Git 2.14.x/2.15 improves the --no-verify behavior:

See commit 680ee55 (14 Aug 2017) by Kevin Willford (``).
^{(Merged by Junio C Hamano -- gitster -- in commit c3e034f, 23 Aug 2017)}

commit: skip discarding the index if there is no pre-commit hook

"git commit" used to discard the index and re-read from the filesystem just in case the pre-commit hook has updated it in the middle; this has been optimized out when we know we do not run the pre-commit hook.

Davi Lima points out in the comments the git cherry-pick does not support --no-verify.
So if a cherry-pick triggers a pre-commit hook, you might, as in this blog post, have to comment/disable somehow that hook in order for your git cherry-pick to proceed.
The same process would be necessary in case of a git rebase --continue, after a merge conflict resolution.

html, body{ 
  width:100%;
}

This tells the html to be 100% wide. But 100% refers to the whole browser window width, so no more than that.

You may want to set a min width instead.

html, body{ 
  min-width:100%;
}

So it will be 100% as a minimum, bot more if needed.

A) For a cheap comparison / arithmetics dummy use math.inf. Or math.nan, which compares FALSE in any direction (including nan == nan) except identity check (is) and renders any arithmetics (like nan - nan) nan. Or a reasonably high real integer number according to your use case (e.g. sys.maxsize). For a bitmask dummy (e.g. in mybits & bitmask) use -1.

B) To get the platform primitive maximum signed long int (or long long):

>>> 256 ** sys.int_info.sizeof_digit // 2 - 1  # Python’s internal primitive
2147483647
>>> 256 ** ctypes.sizeof(ctypes.c_long) // 2 - 1  # CPython
2147483647
>>> 256 ** ctypes.sizeof(ctypes.c_longlong) // 2 - 1  # CPython
9223372036854775807
>>> 2**63 - 1  # Java / JPython primitive long
9223372036854775807

C) The maximum Python integer could be estimated by a long running loop teasing for a memory overflow (try 256**int(8e9) - can be stopped by KeyboardInterrupt). But it cannot not be used reasonably, because its representation already consumes all the memory and its much greater than sys.float_info.max.

You can change this one parent attribute ="android:style/Theme.Holo.Light.DarkActionBar"

                //smalest number in the array//
    double small = x[0];
    for(t=0;t<x[t];t++)
    {
         if(x[t]<small)
             {
                small=x[t];
            }
    }
    printf("\nThe smallest number is  %0.2lf  \n",small);

This example reads 6 bytes into a byte array and writes it to another byte array. It does an XOR operation with the bytes so that the result written to the file is the same as the original starting values. The file is always 6 bytes in size, since it writes at position 0.

using System;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main()
        {
        byte[] b1 = { 1, 2, 4, 8, 16, 32 };
        byte[] b2 = new byte[6];
        byte[] b3 = new byte[6];
        byte[] b4 = new byte[6];

        FileStream f1;
        f1 = new FileStream("test.txt", FileMode.Create, FileAccess.Write);

        // write the byte array into a new file
        f1.Write(b1, 0, 6);
        f1.Close();

        // read the byte array
        f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Read);

        f1.Read(b2, 0, 6);
        f1.Close();

        // make changes to the byte array
        for (int i = 1; i < b2.Length; i++)
        {
            b2[i] = (byte)(b2[i] ^ (byte)10); //xor 10
        }

        f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Write);
        // write the new byte array into the file
        f1.Write(b2, 0, 6);
        f1.Close();

        f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Read);

        // read the byte array
        f1.Read(b3, 0, 6);
        f1.Close();

        // make changes to the byte array
        for (int i = 1; i < b3.Length; i++)
        {
            b4[i] = (byte)(b3[i] ^ (byte)10); //xor 10
        }

        f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Write);

        // b4 will have the same values as b1
        f1.Write(b4, 0, 6);
        f1.Close();
        }
    }
}

This function doesn't fail for more than two duplicates values:

function unique(arr) {
    var a = [];
    var l = arr.length;
    for(var i=0; i<l; i++) {
        for(var j=i+1; j<l; j++) {
            // If a[i] is found later in the array
            if (arr[i] === arr[j])
              j = ++i;
        }
        a.push(arr[i]);
    }
    return a;
};

I take this and it works.

You don't really need to use Singleton pattern because it's considered to be an antipattern. Basically there is a lot of reasons to not to implement this pattern at all. Read this to start with: Best practice on PHP singleton classes.

If after all you still think you need to use Singleton pattern then we could write a class that will allow us to get Singleton functionality by extending our SingletonClassVendor abstract class.

This is what I came with to solve this problem.

<?php
namespace wl;


/**
 * @author DevWL
 * @dosc allows only one instance for each extending class.
 * it acts a litle bit as registry from the SingletonClassVendor abstract class point of view
 * but it provides a valid singleton behaviour for its children classes
 * Be aware, the singleton pattern is consider to be an anti-pattern
 * mostly because it can be hard to debug and it comes with some limitations.
 * In most cases you do not need to use singleton pattern
 * so take a longer moment to think about it before you use it.
 */
abstract class SingletonClassVendor
{
    /**
     *  holds an single instance of the child class
     *
     *  @var array of objects
     */
    protected static $instance = [];

    /**
     *  @desc provides a single slot to hold an instance interchanble between all child classes.
     *  @return object
     */
    public static final function getInstance(){
        $class = get_called_class(); // or get_class(new static());
        if(!isset(self::$instance[$class]) || !self::$instance[$class] instanceof $class){
            self::$instance[$class] = new static(); // create and instance of child class which extends Singleton super class
            echo "new ". $class . PHP_EOL; // remove this line after testing
            return  self::$instance[$class]; // remove this line after testing
        }
        echo "old ". $class . PHP_EOL; // remove this line after testing
        return static::$instance[$class];
    }

    /**
     * Make constructor abstract to force protected implementation of the __constructor() method, so that nobody can call directly "new Class()".
     */
    abstract protected function __construct();

    /**
     * Make clone magic method private, so nobody can clone instance.
     */
    private function __clone() {}

    /**
     * Make sleep magic method private, so nobody can serialize instance.
     */
    private function __sleep() {}

    /**
     * Make wakeup magic method private, so nobody can unserialize instance.
     */
    private function __wakeup() {}

}

Use example:

/**
 * EXAMPLE
 */

/**
 *  @example 1 - Database class by extending SingletonClassVendor abstract class becomes fully functional singleton
 *  __constructor must be set to protected becaouse: 
 *   1 to allow instansiation from parent class 
 *   2 to prevent direct instanciation of object with "new" keword.
 *   3 to meet requierments of SingletonClassVendor abstract class
 */
class Database extends SingletonClassVendor
{
    public $type = "SomeClass";
    protected function __construct(){
        echo "DDDDDDDDD". PHP_EOL; // remove this line after testing
    }
}


/**
 *  @example 2 - Config ...
 */
class Config extends SingletonClassVendor
{
    public $name = "Config";
    protected function __construct(){
        echo "CCCCCCCCCC" . PHP_EOL; // remove this line after testing
    }
}

Just to prove that it works as expected:

/**
 *  TESTING
 */
$bd1 = Database::getInstance(); // new
$bd2 = Database::getInstance(); // old
$bd3 = Config::getInstance(); // new
$bd4 = Config::getInstance(); // old
$bd5 = Config::getInstance(); // old
$bd6 = Database::getInstance(); // old
$bd7 = Database::getInstance(); // old
$bd8 = Config::getInstance(); // old

echo PHP_EOL."COMPARE ALL DATABASE INSTANCES".PHP_EOL;
var_dump($bd1);
echo '$bd1 === $bd2' . ($bd1 === $bd2)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE
echo '$bd2 === $bd6' . ($bd2 === $bd6)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE
echo '$bd6 === $bd7' . ($bd6 === $bd7)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE

echo PHP_EOL;

echo PHP_EOL."COMPARE ALL CONFIG INSTANCES". PHP_EOL;
var_dump($bd3);
echo '$bd3 === $bd4' . ($bd3 === $bd4)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE
echo '$bd4 === $bd5' . ($bd4 === $bd5)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE
echo '$bd5 === $bd8' . ($bd5 === $bd8)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE

If you don't want to register a listener on every component,
you could add your own KeyEventDispatcher to the KeyboardFocusManager:

public class MyFrame extends JFrame {    
    private class MyDispatcher implements KeyEventDispatcher {
        @Override
        public boolean dispatchKeyEvent(KeyEvent e) {
            if (e.getID() == KeyEvent.KEY_PRESSED) {
                System.out.println("tester");
            } else if (e.getID() == KeyEvent.KEY_RELEASED) {
                System.out.println("2test2");
            } else if (e.getID() == KeyEvent.KEY_TYPED) {
                System.out.println("3test3");
            }
            return false;
        }
    }
    public MyFrame() {
        add(new JTextField());
        System.out.println("test");
        KeyboardFocusManager manager = KeyboardFocusManager.getCurrentKeyboardFocusManager();
        manager.addKeyEventDispatcher(new MyDispatcher());
    }

    public static void main(String[] args) {
        MyFrame f = new MyFrame();
        f.pack();
        f.setVisible(true);
    }
}

I have found the designer "update from database" can only handle small changes. If you have deleted tables, changed foreign keys or (gasp) changed the signature of a stored procedure with a function mapping, you will eventually get to such a messed up state you will have to either delete all the entities and "add from database" or simply delete the edmx resource and start over.

This is a better way to center UL's inside of any DIV container.

This CSS solution does not use Width and Float properties. Float:Left and Width: 70%, will cause you headaches when you need to duplicate your menu on different pages with different menu items.

Instead of using width, we use padding and margin to determine the space around the text/menu item. Also, instead of using Float:Left in the LI element, use display:inline-block.

By floating your LI left, you literally float your content to the left and then you must use one of the Hacks mentioned above to center your UL. Display:inline-block creates your Float property for you (sort of). It takes your LI element and turns it into a block element that lays side by side each other (not floating).

With Responsive design and using frameworks like Bootstrap or Foundation, there will be issues when trying to float and center content. They have some built-in classes, but it's always better to do it from scratch. This solution is much better for dynamic menus (Such as Adobe Business Catalyst menu system).

If you clone with the --depth parameter, it sets .git/config not to fetch all branches, but only master.

You can simply omit the parameter or update the configuration file from

fetch = +refs/heads/master:refs/remotes/origin/master

to

fetch = +refs/heads/*:refs/remotes/origin/*

If you are using the Gradle Wrapper (the recommended option in Android Studio), you enable stacktrace by running gradlew compileDebug --stacktrace from the command line in the root folder of your project (where the gradlew file is).

If you are not using the gradle wrapper, you use gradle compileDebug --stacktrace instead (presumably).

You don't really need to run with --stacktrace though, running gradlew compileDebug by itself, from the command line, should tell you where the error is.

I based this information on this comment:

Android Studio new project can not run, throwing error

In case you want to run a PowerShell script with Windows Task Scheduler, please follow the steps below:

1. Create a task

2. Set Program/Script to Powershell.exe

3. Set Arguments to -File "C:\xxx.ps1"

It's from another answer, How do I execute a PowerShell script automatically using Windows task scheduler?.

Integer refers to wrapper type in Java whereas int is a primitive type. Everything except primitive data types in Java is implemented just as objects that implies Java is a highly qualified pure object-oriented programming language. If you need, all primitives types are also available as wrapper types in Java. You can have some performance benefit with primitive types, and hence wrapper types should be used only when it is necessary.

In your example as below.

Integer n = 9;

the constant 9 is being auto-boxed (auto-boxing and unboxing occurs automatically from java 5 onwards) to Integer and therefore you can use the statement like that and also Integer n = new Integer(9). This is actually achieved through the statement Integer.valueOf(9).intValue();

Not quite perfect, but it got me closer than some of the top answers here.

Two different tables, one with the header, and the other, wrapped with a div with the content

<table>
  <thead>
    <tr><th>Stuff</th><th>Second Stuff</th></tr>
  </thead>
</table>
<div style="height: 600px; overflow: auto;">
  <table>
    <tbody>
      //Table
    </tbody>
  </table>
</div>

According to a react developer, you dont need the namespace xmlns. If you need the attribute xlink:href you can use xlinkHref from react 0.14

Example

Icon = (props) => {
  return <svg className="icon">
    <use xlinkHref={ '#' + props.name }></use>
  </svg>;
}

That can be done using the limit function, this might not seem new but i have added something.The code should go:

SELECT * FROM table_name LIMIT 100,10;

for the above case assume that you have 110 rows from the table and you want to select the last ten, 100 is the row you want to start to print(if you are to print), and ten shows how many rows you want to pick from the table. For a more precised way you can start by selecting all the rows you want to print out and then you grab the last row id if you have an id column(i recommend you put one) then subtract ten from the last id number and that will be where you want to start, this will make your program to function autonomously and for any number of rows, but if you write the value directly i think you will have to change the code every time data is inserted into your table.I think this helps.Pax et Bonum.

I encountered similar issue when uploading a file returned 409.

Besides issues mentioned above it can also happen due to file size restrictions for POST on the server side. For example, tomcat (java web server) have POST size limit of 2MB by default.

    }

4. Make sure these permission are written in Manifest file

   <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

   

5. Add following dependencies

   implementation 'com.google.android.gms:play-services-maps:17.0.0'

   implementation 'com.google.android.gms:play-services-location:17.0.0'

   

This answer does not fully deal with the OP, but there are have been several times I have had a similar problem and searched for the answer.

If you can recreate the formula or the data if needed (and from your description it looks as if you can), then when you are ready to run the portion that requires the blank cells to be actually empty, then you can select the region and run the following vba macro.

Sub clearBlanks()
    Dim r As Range
    For Each r In Selection.Cells
        If Len(r.Text) = 0 Then
            r.Clear
        End If
    Next r
End Sub

this will wipe out off of the contents of any cell which is currently showing "" or has only a formula

I agree with @haha on this one, for the most part. But there are several cross-browser related issues with using the "float:right" and could ultimately give you more of a headache than you want. If you know what the widths are going to be for each column use a float:left on both and save yourself the trouble. Another thing you can incorporate into your methodology is build column classes into your CSS.

So try something like this:

CSS

.col-wrapper{width:960px; margin:0 auto;}
.col{margin:0 10px; float:left; display:inline;}
.col-670{width:670px;}
.col-250{width:250px;}

HTML

<div class="col-wrapper">
    <div class="col col-670">[Page Content]</div>
    <div class="col col-250">[Page Sidebar]</div>
</div>

WHy bother with all of the fancy selectors? If you're using those id="" attributes properly, then 'test2' must be the only tag with that id on the page, then the .checked boolean property will tell you if it's checked or not:

if ($('test2').checked) {
    ....
}

You've also not set any values for those radio buttons, so no matter which button you select, you'll just get a blank "testGroup=" submitted to the server.

When applying CSS, apply it to a class and try to avoid as much as you can to an id. The ID should only be used in JavaScript to fetch the element or for any event binding.

Classes should be used to apply CSS.

Sometimes you do have to use classes for event binding. In such cases, try to avoid classes which are being used for applying CSS and rather add new classes which doesn't have corresponding CSS. This will come to help when you need to change the CSS for any class or change the CSS class name all together for any element.

You need to use an explicit color value (e.g. #000 or blue) for the color-property. none is invalid here. The initial value is browser-specific and cannot be restored using CSS. Keep in mind that there are some other pseudo-classes than :active, too.

Sometimes, the minimal installation of Linux in Docker doesn't define the path and therefore it is necessary to call ping using ....

Why use the canvas to resize images? Modern browsers all use bicubic interpolation — the same process used by Photoshop (if you're doing it right) — and they do it faster than the canvas process. Just specify the image size you want (use only one dimension, height or width, to resize proportionally).

This is supported by most browsers, including later versions of IE. Earlier versions may require browser-specific CSS.

A simple function (using jQuery) to resize an image would be like this:

function resizeImage(img, percentage) {
    var coeff = percentage/100,
        width = $(img).width(),
        height = $(img).height();

    return {"width": width*coeff, "height": height*coeff}           
}

Then just use the returned value to resize the image in one or both dimensions.

Obviously there are different refinements you could make, but this gets the job done.

Paste the following code into the console of this page and watch what happens to the gravatars:

function resizeImage(img, percentage) {
    var coeff = percentage/100,
        width = $(img).width(),
        height = $(img).height();

    return {"width": width*coeff, "height": height*coeff}           
}

$('.user-gravatar32 img').each(function(){
  var newDimensions = resizeImage( this, 150);
  this.style.width = newDimensions.width + "px";
  this.style.height = newDimensions.height + "px";
});

According to MSDN, the JavaScript Date object does not provide any specific date formatting methods (as you may see with other programming languages). However, you can use a few of the Date methods and formatting to accomplish your goal:

function dateToString (date) {
  // Use an array to format the month numbers
  var months = [
    "January",
    "February",
    "March",
    ...
  ];

  // Use an object to format the timezone identifiers
  var timeZones = {
    "360": "EST",
    ...
  };

  var month = months[date.getMonth()];
  var day = date.getDate();
  var year = date.getFullYear();

  var hours = date.getHours();
  var minutes = date.getMinutes();
  var time = (hours > 11 ? (hours - 11) : (hours + 1)) + ":" + minutes + (hours > 11 ? "PM" : "AM");
  var timezone = timeZones[date.getTimezoneOffset()];

  // Returns formatted date as string (e.g. January 28, 2011 - 7:30PM EST)
  return month + " " + day + ", " + year + " - " + time + " " + timezone;
}

var date = new Date("2011-01-28T19:30:00-05:00");

alert(dateToString(date));

You could even take it one step further and override the Date.toString() method:

function dateToString () { // No date argument this time
  // Use an array to format the month numbers
  var months = [
    "January",
    "February",
    "March",
    ...
  ];

  // Use an object to format the timezone identifiers
  var timeZones = {
    "360": "EST",
    ...
  };

  var month = months[*this*.getMonth()];
  var day = *this*.getDate();
  var year = *this*.getFullYear();

  var hours = *this*.getHours();
  var minutes = *this*.getMinutes();
  var time = (hours > 11 ? (hours - 11) : (hours + 1)) + ":" + minutes + (hours > 11 ? "PM" : "AM");
  var timezone = timeZones[*this*.getTimezoneOffset()];

  // Returns formatted date as string (e.g. January 28, 2011 - 7:30PM EST)
  return month + " " + day + ", " + year + " - " + time + " " + timezone;
}

var date = new Date("2011-01-28T19:30:00-05:00");
Date.prototype.toString = dateToString;

alert(date.toString());

I know this question is old but in case if anyone will look for it in the future. It is possible to have two captcha's on one page. Pink to documentation is here: https://developers.google.com/recaptcha/docs/display Example below is just a copy form doc and you dont have to specify different layouts.

<script type="text/javascript">
  var verifyCallback = function(response) {
    alert(response);
  };
  var widgetId1;
  var widgetId2;
  var onloadCallback = function() {
    // Renders the HTML element with id 'example1' as a reCAPTCHA widget.
    // The id of the reCAPTCHA widget is assigned to 'widgetId1'.
    widgetId1 = grecaptcha.render('example1', {
      'sitekey' : 'your_site_key',
      'theme' : 'light'
    });
    widgetId2 = grecaptcha.render(document.getElementById('example2'), {
      'sitekey' : 'your_site_key'
    });
    grecaptcha.render('example3', {
      'sitekey' : 'your_site_key',
      'callback' : verifyCallback,
      'theme' : 'dark'
    });
  };
</script>

Just append :after to your #alertlist li:hover selector the same way you do with your #alertlist li.selected selector:

#alertlist li.selected:after, #alertlist li:hover:after
{
    position:absolute;
    top: 0;
    right:-10px;
    bottom:0;

    border-top: 10px solid transparent;
    border-bottom: 10px solid transparent;
    border-left: 10px solid #303030;
    content: "";
}

OperationalError: Lost connection to HANA server (ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None))

I tried to run the code for connection(mentioned below), which created that error, again and it worked.

    import pyhdb
    connection = pyhdb.connect(host="example.com",port=30015,user="user",password="secret")
    cursor = connection.cursor()
    cursor.execute("SELECT 'Hello Python World' FROM DUMMY")
    cursor.fetchone()
    connection.close()

It was because the server refused to connect. It might require you to wait for a while and try again. Try closing the Hana Studio by logging off and then logging in again. Keep running the code for a number of times.

? TWO Simple Solutions:

To install the latest version of node and reinstall the old version packages just run the following command.

nvm install node --reinstall-packages-from=node

To install the latest lts (long term support) version of node and reinstall the old version packages just run the following command.

nvm install --lts /* --reinstall-packages-from=node

Here's a GIF to support this answer.

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Core Java Vol 1 and 2.

Pandas uses matplotlib as a library for basic plots. The easiest way in your case will using the following:

import pandas as pd
import numpy as np

#creating sample data 
sample_data={'col_name_1':np.random.rand(20),
      'col_name_2': np.random.rand(20)}
df= pd.DataFrame(sample_data)
df.plot(x='col_name_1', y='col_name_2', style='o')

However, I would recommend to use seaborn as an alternative solution if you want have more customized plots while not going into the basic level of matplotlib. In this case you the solution will be following:

import pandas as pd
import seaborn as sns
import numpy as np

#creating sample data 
sample_data={'col_name_1':np.random.rand(20),
      'col_name_2': np.random.rand(20)}
df= pd.DataFrame(sample_data)
sns.scatterplot(x="col_name_1", y="col_name_2", data=df)

You can also use it like this.
