There is a possibility not to use extra variables

String s = "HelloSuresh";
s = s.replace("Hello","");
System.out.println(s);

In python3.7.7, the definition of json.load is as below according to cpython source code:

def load(fp, *, cls=None, object_hook=None, parse_float=None,
        parse_int=None, parse_constant=None, object_pairs_hook=None, **kw):

    return loads(fp.read(),
        cls=cls, object_hook=object_hook,
        parse_float=parse_float, parse_int=parse_int,
        parse_constant=parse_constant, object_pairs_hook=object_pairs_hook, **kw)

json.load actually calls json.loads and use fp.read() as the first argument.

So if your code is:

with open (file) as fp:
    s = fp.read()
    json.loads(s)

It's the same to do this:

with open (file) as fp:
    json.load(fp)

But if you need to specify the bytes reading from the file as like fp.read(10) or the string/bytes you want to deserialize is not from file, you should use json.loads()

As for json.loads(), it not only deserialize string but also bytes. If s is bytes or bytearray, it will be decoded to string first. You can also find it in the source code.

def loads(s, *, encoding=None, cls=None, object_hook=None, parse_float=None,
        parse_int=None, parse_constant=None, object_pairs_hook=None, **kw):
    """Deserialize ``s`` (a ``str``, ``bytes`` or ``bytearray`` instance
    containing a JSON document) to a Python object.

    ...

    """
    if isinstance(s, str):
        if s.startswith('\ufeff'):
            raise JSONDecodeError("Unexpected UTF-8 BOM (decode using utf-8-sig)",
                                  s, 0)
    else:
        if not isinstance(s, (bytes, bytearray)):
            raise TypeError(f'the JSON object must be str, bytes or bytearray, '
                            f'not {s.__class__.__name__}')
        s = s.decode(detect_encoding(s), 'surrogatepass')

Integer has no method length. Try string

var testvar={};
testvar[1]="2";
alert(testvar[1].length);

In your request options, try including the following:

   var req = https.request({ 
      host: '192.168.1.1', 
      port: 443,
      path: '/',
      method: 'GET',
      rejectUnauthorized: false,
      requestCert: true,
      agent: false
    },

I know this is an old question, but it might be worth mentioning that you can create your own configurations outside of DEBUG and RELEASE, such as TEST or UAT.

If then on the Build tab of the project properties page you then set the "Conditional compilation symbols" to TEST (for instance) you can then use a construct such as

#if (DEBUG || TEST )
    //Code that will not be executed in RELEASE or UAT
#endif

You can use this construct for specific reason such as different clients if you have the need, or even entire Web Methods for instance. We have also used this in the past where some commands have caused issues on specific hardware, so we have a configuration for an app when deployed to hardware X.

var request = require('request');
request.post('http://localhost/test2.php', 
    {form:{ mes: "heydude" }}, 
    function(error, response, body){
        console.log(body);
});

Use the pdfpages package.

\usepackage{pdfpages}

To include all the pages in the PDF file:

\includepdf[pages=-]{myfile.pdf}

To include just the first page of a PDF:

\includepdf[pages={1}]{myfile.pdf}

Run texdoc pdfpages in a shell to see the complete manual for pdfpages.

Giving below another option. This will zip up a full folder and will write the archive to a given path with the given name.

Requires .NET 3 or above

Add-Type -assembly "system.io.compression.filesystem"

$source = 'Source path here'    
$destination = "c:\output\dummy.zip"

If(Test-path $destination) {Remove-item $destination}

[io.compression.zipfile]::CreateFromDirectory($Source, $destination)

As per this post:

end((explode('-', $string)));

which won't cause E_STRICT warning in PHP 5 (PHP magic). Although the warning will be issued in PHP 7, so adding @ in front of it can be used as a workaround.

For Angular2 + Material2 + Sidenav, you'll need to do the following:

 ngAfterViewInit() {
   this.element.nativeElement.getElementsByClassName('md-sidenav-content')[0].style.overflow = 'hidden'; 
  }

Looking through your exact question to your implied problem:

Step 1: Use the class as you described (or, if you must, use inline styles).

Step 2: Turn on GZIP compression.

Works wonders ;)

This way GZIP removes the redundancy for you (over the wire, anyways) and your source remains standards compliant.

Event listeners

First off it's important to understand that there are two kinds of "event listeners":

1. Scope event listeners registered via $on:

   $scope.$on('anEvent', function (event, data) {
     ...
   });
   

2. Event handlers attached to elements via for example on or bind:

   element.on('click', function (event) {
     ...
   });
   

$scope.$destroy()

When $scope.$destroy() is executed it will remove all listeners registered via $on on that $scope.

It will not remove DOM elements or any attached event handlers of the second kind.

This means that calling $scope.$destroy() manually from example within a directive's link function will not remove a handler attached via for example element.on, nor the DOM element itself.

element.remove()

Note that remove is a jqLite method (or a jQuery method if jQuery is loaded before AngularjS) and is not available on a standard DOM Element Object.

When element.remove() is executed that element and all of its children will be removed from the DOM together will all event handlers attached via for example element.on.

It will not destroy the $scope associated with the element.

To make it more confusing there is also a jQuery event called $destroy. Sometimes when working with third-party jQuery libraries that remove elements, or if you remove them manually, you might need to perform clean up when that happens:

element.on('$destroy', function () {
  scope.$destroy();
});

What to do when a directive is "destroyed"

This depends on how the directive is "destroyed".

A normal case is that a directive is destroyed because ng-view changes the current view. When this happens the ng-view directive will destroy the associated $scope, sever all the references to its parent scope and call remove() on the element.

This means that if that view contains a directive with this in its link function when it's destroyed by ng-view:

scope.$on('anEvent', function () {
 ...
});

element.on('click', function () {
 ...
});

Both event listeners will be removed automatically.

However, it's important to note that the code inside these listeners can still cause memory leaks, for example if you have achieved the common JS memory leak pattern circular references.

Even in this normal case of a directive getting destroyed due to a view changing there are things you might need to manually clean up.

For example if you have registered a listener on $rootScope:

var unregisterFn = $rootScope.$on('anEvent', function () {});

scope.$on('$destroy', unregisterFn);

This is needed since $rootScope is never destroyed during the lifetime of the application.

The same goes if you are using another pub/sub implementation that doesn't automatically perform the necessary cleanup when the $scope is destroyed, or if your directive passes callbacks to services.

Another situation would be to cancel $interval/$timeout:

var promise = $interval(function () {}, 1000);

scope.$on('$destroy', function () {
  $interval.cancel(promise);
});

If your directive attaches event handlers to elements for example outside the current view, you need to manually clean those up as well:

var windowClick = function () {
   ...
};

angular.element(window).on('click', windowClick);

scope.$on('$destroy', function () {
  angular.element(window).off('click', windowClick);
});

These were some examples of what to do when directives are "destroyed" by Angular, for example by ng-view or ng-if.

If you have custom directives that manage the lifecycle of DOM elements etc. it will of course get more complex.

Alternative: Stream.concat()

Stream.concat(map.values().stream(), listContainer.lst.stream())
                             .collect(Collectors.toList()

Do a reset of the configuration and set the root level to OFF

LogManager.getLogManager().reset();
Logger globalLogger = Logger.getLogger(java.util.logging.Logger.GLOBAL_LOGGER_NAME);
globalLogger.setLevel(java.util.logging.Level.OFF);

Use Ctrl+Enter on Mac to get list of options to generate setter, getter, constructor etc

If you want to change inputs in an iframe then submit the form from that iframe, do this

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

var doc, frame_win = getIframeWindow(el); // getIframeWindow is defined below

if (frame_win) {
  doc = (window.contentDocument || window.document);
}

if (doc) {
  doc.forms[0].someInputName.value = someValue;
  ...
  doc.forms[0].submit();
}
...

Normally, you can only do this if the page in the iframe is from the same origin, but you can start Chrome in a debug mode to disregard the same origin policy and test this on any page.

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;
}

You can print some text by using SELECT command like that:

SELECT 'some text'

Result:

+-----------+
| some text |
+-----------+
| some text |
+-----------+
1 row in set (0.02 sec)

The answers above were all assuming your Python distribution would have some third-party libraries in order to achieve the "one liner python ftpd" goal, but that is not the case of what @zio was asking. Also, SimpleHTTPServer involves web broswer for downloading files, it's not quick enough.

Python can't do ftpd by itself, but you can use netcat, nc:

nc is basically a built-in tool from any UNIX-like systems (even embedded systems), so it's perfect for "quick and temporary way to transfer files".

Step 1, on the receiver side, run:

nc -l 12345 | tar -xf -

this will listen on port 12345, waiting for data.

Step 2, on the sender side:

tar -cf - ALL_FILES_YOU_WANT_TO_SEND ... | nc $RECEIVER_IP 12345

You can also put pv in the middle to monitor the progress of transferring:

tar -cf - ALL_FILES_YOU_WANT_TO_SEND ...| pv | nc $RECEIVER_IP 12345

After the transferring is finished, both sides of nc will quit automatically, and job done.

In my case I solved the problem by establishing a valid column number when applying the order property inside the script where you configure the data table.

var table = $('#mytable').DataTable({
     .
     .
     .
     order: [[ 1, "desc" ]],

You can make the copy constructor private and provide no implementation:

private:
    SymbolIndexer(const SymbolIndexer&);

Or in C++11, explicitly forbid it:

SymbolIndexer(const SymbolIndexer&) = delete;

You can do this with jquery just visit http://jquery.com/ to get the link then do something like this

<a id="show_image">Show Image</a>
<img id="my_images" style="display:none" src="http://myimages.com/img.png">

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
   $(document).ready(function(){
      $('#show_image').on("click", function(){
         $('#my_images').show('slow');
      });
   });
</script>

or if you would like the link to turn the image on and off do this

<a id="show_image">Show Image</a>
<img id="my_images" style="display:none;" src="http://myimages.com/img.png">

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
   $(document).ready(function(){
      $('#show_image').on("click", function(){
         $('#my_images').toggle();
      });
   });
</script>

Tried the above solutions with no luck ... restarted my mac solved the issue...

If your iframe is in the same domain as your parent page you can access the elements using document.frames collection.

// replace myIFrame with your iFrame id
// replace myIFrameElemId with your iFrame's element id
// you can work on document.frames['myIFrame'].document like you are working on
// normal document object in JS
window.frames['myIFrame'].document.getElementById('myIFrameElemId')

If your iframe is not in the same domain the browser should prevent such access for security reasons.

For deleting a dynamic array in VBA use the instruction Erase.

Example:

Dim ArrayDin() As Integer    
ReDim ArrayDin(10)    'Dynamic allocation 
Erase ArrayDin        'Erasing the Array   

Hope this help!

To prevent a long line of commands in a text file, I keep my copy-pase snippets like this:

echo a;\
echo b;\
echo c

You may also try downloading newest version of adb http://developer.android.com/tools/help/adb.html

Even this works.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@color/dim_orange_btn_pressed" />
    <item android:state_focused="true" android:drawable="@color/dim_orange_btn_pressed" />
    <item android:drawable="@android:color/white" />
</selector>

I added the android:drawable attribute to each item, and their values are colors.

By the way, why do they say that color is one of the attributes of selector? They don't write that android:drawable is required.

Color State List Resource

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:color="hex_color"
        android:state_pressed=["true" | "false"]
        android:state_focused=["true" | "false"]
        android:state_selected=["true" | "false"]
        android:state_checkable=["true" | "false"]

</selector>

Prevent Screen Rotation just add this following line in your Manifests.

<activity
        android:name=".YourActivity"
        android:screenOrientation="portrait" />

This works for me.

The other option to try is a straightforward

<img width="100" height="100" src="/root/Image/image.jpeg" class="CalloutRightPhoto"/>

i.e. without {} but instead giving the direct image path

You can use an emulation of cls with for (int i = 0; i < 50; ++i) System.out.println();

Short version:

Suppose you have two tensors, where y_hat contains computed scores for each class (for example, from y = W*x +b) and y_true contains one-hot encoded true labels.

y_hat  = ... # Predicted label, e.g. y = tf.matmul(X, W) + b
y_true = ... # True label, one-hot encoded

If you interpret the scores in y_hat as unnormalized log probabilities, then they are logits.

Additionally, the total cross-entropy loss computed in this manner:

y_hat_softmax = tf.nn.softmax(y_hat)
total_loss = tf.reduce_mean(-tf.reduce_sum(y_true * tf.log(y_hat_softmax), [1]))

is essentially equivalent to the total cross-entropy loss computed with the function softmax_cross_entropy_with_logits():

total_loss = tf.reduce_mean(tf.nn.softmax_cross_entropy_with_logits(y_hat, y_true))

Long version:

In the output layer of your neural network, you will probably compute an array that contains the class scores for each of your training instances, such as from a computation y_hat = W*x + b. To serve as an example, below I've created a y_hat as a 2 x 3 array, where the rows correspond to the training instances and the columns correspond to classes. So here there are 2 training instances and 3 classes.

import tensorflow as tf
import numpy as np

sess = tf.Session()

# Create example y_hat.
y_hat = tf.convert_to_tensor(np.array([[0.5, 1.5, 0.1],[2.2, 1.3, 1.7]]))
sess.run(y_hat)
# array([[ 0.5,  1.5,  0.1],
#        [ 2.2,  1.3,  1.7]])

Note that the values are not normalized (i.e. the rows don't add up to 1). In order to normalize them, we can apply the softmax function, which interprets the input as unnormalized log probabilities (aka logits) and outputs normalized linear probabilities.

y_hat_softmax = tf.nn.softmax(y_hat)
sess.run(y_hat_softmax)
# array([[ 0.227863  ,  0.61939586,  0.15274114],
#        [ 0.49674623,  0.20196195,  0.30129182]])

It's important to fully understand what the softmax output is saying. Below I've shown a table that more clearly represents the output above. It can be seen that, for example, the probability of training instance 1 being "Class 2" is 0.619. The class probabilities for each training instance are normalized, so the sum of each row is 1.0.

                      Pr(Class 1)  Pr(Class 2)  Pr(Class 3)
                    ,--------------------------------------
Training instance 1 | 0.227863   | 0.61939586 | 0.15274114
Training instance 2 | 0.49674623 | 0.20196195 | 0.30129182

So now we have class probabilities for each training instance, where we can take the argmax() of each row to generate a final classification. From above, we may generate that training instance 1 belongs to "Class 2" and training instance 2 belongs to "Class 1".

Are these classifications correct? We need to measure against the true labels from the training set. You will need a one-hot encoded y_true array, where again the rows are training instances and columns are classes. Below I've created an example y_true one-hot array where the true label for training instance 1 is "Class 2" and the true label for training instance 2 is "Class 3".

y_true = tf.convert_to_tensor(np.array([[0.0, 1.0, 0.0],[0.0, 0.0, 1.0]]))
sess.run(y_true)
# array([[ 0.,  1.,  0.],
#        [ 0.,  0.,  1.]])

Is the probability distribution in y_hat_softmax close to the probability distribution in y_true? We can use cross-entropy loss to measure the error.

We can compute the cross-entropy loss on a row-wise basis and see the results. Below we can see that training instance 1 has a loss of 0.479, while training instance 2 has a higher loss of 1.200. This result makes sense because in our example above, y_hat_softmax showed that training instance 1's highest probability was for "Class 2", which matches training instance 1 in y_true; however, the prediction for training instance 2 showed a highest probability for "Class 1", which does not match the true class "Class 3".

loss_per_instance_1 = -tf.reduce_sum(y_true * tf.log(y_hat_softmax), reduction_indices=[1])
sess.run(loss_per_instance_1)
# array([ 0.4790107 ,  1.19967598])

What we really want is the total loss over all the training instances. So we can compute:

total_loss_1 = tf.reduce_mean(-tf.reduce_sum(y_true * tf.log(y_hat_softmax), reduction_indices=[1]))
sess.run(total_loss_1)
# 0.83934333897877944

Using softmax_cross_entropy_with_logits()

We can instead compute the total cross entropy loss using the tf.nn.softmax_cross_entropy_with_logits() function, as shown below.

loss_per_instance_2 = tf.nn.softmax_cross_entropy_with_logits(y_hat, y_true)
sess.run(loss_per_instance_2)
# array([ 0.4790107 ,  1.19967598])

total_loss_2 = tf.reduce_mean(tf.nn.softmax_cross_entropy_with_logits(y_hat, y_true))
sess.run(total_loss_2)
# 0.83934333897877922

Note that total_loss_1 and total_loss_2 produce essentially equivalent results with some small differences in the very final digits. However, you might as well use the second approach: it takes one less line of code and accumulates less numerical error because the softmax is done for you inside of softmax_cross_entropy_with_logits().

Remove padding between cells inside the table. Just use cellpadding=0 and cellspacing=0 attributes in table tag.

Actually "Sheet1" object / code name can be changed. In VBA, click on Sheet1 in Excel Objects list. In the properties window, you can change Sheet1 to say rng.

Then you can reference rng as a global object without having to create a variable first. So debug.print rng.name works just fine. No more Worksheets("rng").name.

Unlike the tab, the object name has same restrictions as other variables (i.e. no spaces).

Using some text manipulation we can separate each unit of time and then sum them together with their millisecond coefficients.

To show the formulas in the cells use CTRL + `

I think this has improved with recent versions of IntelliJ. In my current version (12.0.2), you can add any number of separate Maven projects to the same "workspace".

The simplest way I've found to do this is to click the little + icon in the "Maven Projects" window (View > Tool Windows > Maven Projects) and then select the additional pom file you want to import.

On modern browsers it's easy: just use the input event along with the inputType attribute:

$(document).on('input', 'input, textarea', function(e){
  if (e.originalEvent.inputType == 'insertFromPaste') {
    alert($(this).val());
  }
});

Just create a folder Files under src and put your file there. This will look like src/Files/myFile.txt

Note: In your code you need to specify like this Files/myFile.txt e.g.

getResource("Files/myFile.txt");

So when you build your project and run the .jar file this should be able to work.

Inside CONCATENATE you can use TRANSPOSE if you expand it (F9) then remove the surrounding {}brackets like this recommends

=CONCATENATE(TRANSPOSE(B2:B19))

Becomes

=CONCATENATE("Oh ","combining ", "a " ...)

You may need to add your own separator on the end, say create a column C and transpose that column.

=B1&" "
=B2&" "
=B3&" "

The call to InitializeComponent() (which is usually called in the default constructor of at least Window and UserControl) is actually a method call to the partial class of the control (rather than a call up the object hierarchy as I first expected).

This method locates a URI to the XAML for the Window/UserControl that is loading, and passes it to the System.Windows.Application.LoadComponent() static method. LoadComponent() loads the XAML file that is located at the passed in URI, and converts it to an instance of the object that is specified by the root element of the XAML file.

In more detail, LoadComponent creates an instance of the XamlParser, and builds a tree of the XAML. Each node is parsed by the XamlParser.ProcessXamlNode(). This gets passed to the BamlRecordWriter class. Some time after this I get a bit lost in how the BAML is converted to objects, but this may be enough to help you on the path to enlightenment.

Note: Interestingly, the InitializeComponent is a method on the System.Windows.Markup.IComponentConnector interface, of which Window/UserControl implement in the partial generated class.

Hope this helps!

+1 to @MartinNuc, you can run the mysql client in batch mode and then you won't see the long stream of "OK" lines.

The amount of time it takes to import a given SQL file depends on a lot of things. Not only the size of the file, but the type of statements in it, how powerful your server server is, and how many other things are running at the same time.

@MartinNuc says he can load 4GB of SQL in 4-5 minutes, but I have run 0.5 GB SQL files and had it take 45 minutes on a smaller server.

We can't really guess how long it will take to run your SQL script on your server.

Re your comment,

@MartinNuc is correct you can choose to make the mysql client print every statement. Or you could open a second session and run mysql> SHOW PROCESSLIST to see what's running. But you probably are more interested in a "percentage done" figure or an estimate for how long it will take to complete the remaining statements.

Sorry, there is no such feature. The mysql client doesn't know how long it will take to run later statements, or even how many there are. So it can't give a meaningful estimate for how much time it will take to complete.

I created a custom useQuery hook

import { useLocation } from "react-router-dom";

const useQuery = (): URLSearchParams => {
  return new URLSearchParams(useLocation().search)
}

export default useQuery

Use it as

const query = useQuery();
const id = query.get("id") as string

Send it as so

history.push({  
 pathname: "/template",
 search: `id=${values.id}`,
});
                  

You can divide seconds by 60 to get the minutes

import time
seconds = time.time()
minutes = seconds / 60
print(minutes)

When you divide it by 60 again, you will get the hours

You could try this to dynamically remove an object from an array without looping through it? Where e and t are just random objects.

>>> e = {'b':1, 'w': 2}
>>> t = {'b':1, 'w': 3}
>>> p = [e,t]
>>> p
[{'b': 1, 'w': 2}, {'b': 1, 'w': 3}]
>>>
>>> p.pop(p.index({'b':1, 'w': 3}))
{'b': 1, 'w': 3}
>>> p
[{'b': 1, 'w': 2}]
>>>

A clean way to delete a cookie is to clear both of $_COOKIE value and browser cookie file :

if (isset($_COOKIE['key'])) {
    unset($_COOKIE['key']);
    setcookie('key', '', time() - 3600, '/'); // empty value and old timestamp
}

Actually The documentation shows that you can use XMLHttpRequest().send() to simply send multiform data in case jquery sucks

Using Java util.Date, here what I did.

    public static boolean checkTimeOverlaps(Date startDate1, Date endDate1, Date startDate2, Date endDate2)
    {
        if (startDate1 == null || endDate1 == null || startDate2 == null || endDate2 == null)
           return false;

        if ((startDate1.getTime() <= endDate2.getTime()) && (startDate2.getTime() <= endDate1.getTime()))
           return true;

        return false;
    }

Technical Answer

Abstract classes cannot be instantiated - this is by definition and design.

From the JLS, Chapter 8. Classes:

A named class may be declared abstract (§8.1.1.1) and must be declared abstract if it is incompletely implemented; such a class cannot be instantiated, but can be extended by subclasses.

From JSE 6 java doc for Classes.newInstance():

InstantiationException - if this Class represents an abstract class, an interface, an array class, a primitive type, or void; or if the class has no nullary constructor; or if the instantiation fails for some other reason.

You can, of course, instantiate a concrete subclass of an abstract class (including an anonymous subclass) and also carry out a typecast of an object reference to an abstract type.

A Different Angle On This - Teamplay & Social Intelligence:

This sort of technical misunderstanding happens frequently in the real world when we deal with complex technologies and legalistic specifications.

"People Skills" can be more important here than "Technical Skills". If competitively and aggressively trying to prove your side of the argument, then you could be theoretically right, but you could also do more damage in having a fight / damaging "face" / creating an enemy than it is worth. Be reconciliatory and understanding in resolving your differences. Who knows - maybe you're "both right" but working off slightly different meanings for terms??

Who knows - though not likely, it is possible the interviewer deliberately introduced a small conflict/misunderstanding to put you into a challenging situation and see how you behave emotionally and socially. Be gracious and constructive with colleagues, follow advice from seniors, and follow through after the interview to resolve any challenge/misunderstanding - via email or phone call. Shows you're motivated and detail-oriented.

If you have a specific integer timestamp to insert/update, you can use PHP date() function with your timestamp as second arg :

date("Y-m-d H:i:s", $myTimestamp)

Not dplyr, but it's much more direct using data.table:

library(data.table)
setDT(df)
df[ df[order(id, stopSequence), .I[c(1L,.N)], by=id]$V1 ]
#    id stopId stopSequence
# 1:  1      a            1
# 2:  1      c            3
# 3:  2      b            1
# 4:  2      c            4
# 5:  3      b            1
# 6:  3      a            3

More detailed explanation:

# 1) get row numbers of first/last observations from each group
#    * basically, we sort the table by id/stopSequence, then,
#      grouping by id, name the row numbers of the first/last
#      observations for each id; since this operation produces
#      a data.table
#    * .I is data.table shorthand for the row number
#    * here, to be maximally explicit, I've named the variable V1
#      as row_num to give other readers of my code a clearer
#      understanding of what operation is producing what variable
first_last = df[order(id, stopSequence), .(row_num = .I[c(1L,.N)]), by=id]
idx = first_last$row_num

# 2) extract rows by number
df[idx]

Be sure to check out the Getting Started wiki for getting the data.table basics covered

In my case, I forgot to add git to the respository name at the end.

I think Disjoint Set is pretty nifty for cases when you need to divide a bunch of items into distinct sets and query membership. Good implementation of the Union and Find operations result in amortized costs that are effectively constant (inverse of Ackermnan's Function, if I recall my data structures class correctly).

If you can change the signature of your function to async Task then you can use the code presented here

You can use Django's built-in validators—

from django.db.models import IntegerField, Model
from django.core.validators import MaxValueValidator, MinValueValidator

class CoolModelBro(Model):
    limited_integer_field = IntegerField(
        default=1,
        validators=[
            MaxValueValidator(100),
            MinValueValidator(1)
        ]
     )

Edit: When working directly with the model, make sure to call the model full_clean method before saving the model in order to trigger the validators. This is not required when using ModelForm since the forms will do that automatically.

Try this:

btn.requestFocusFromTouch();

There is a shortcut (Ctrl+Shift+A for Windows and Linux users, Command+Shift+A for Mac users) to select the whole block within the currently selected tag.

For example, if you pressed this while your text cursor was within the outer div tag in the code below, all the divs with class selected would be selected.

<div class='current_tag_block'>
  <div class='selected'></div>
  <div class='selected'></div>
  <div class='selected'></div>
  <div class='selected'></div>
</div>

Set up a virtualenv:

% curl -kLso /tmp/get-pip.py https://bootstrap.pypa.io/get-pip.py 
% sudo python /tmp/get-pip.py

These commands install pip into the global site-packages directory.

% sudo pip install virtualenv

and ditto for virtualenv:

% mkdir -p ~/.virtualenvs

I like my virtualenvs under one tree in my home directory called .virtualenvs

% virtualenv ~/.virtualenvs/lxmltest

Creates a virtualenv.

% . ~/.virtualenvs/lxmltest/bin/activate

Removes the need to specify the full path to pip/python in this virtualenv.

% pip install lxml

Alternatively execute ~/.virtualenvs/lxmltest/bin/pip install lxml if you chose not to follow the previous step. Note, I'm not sure how far along you are, so some of these steps can be safely skipped. Of course, if you mess something up, you can always rm -Rf ~/.virtualenvs/lxmltest and start again from a new virtualenv.

For situations when I need to replace or match(find) something against string I prefer using regular expressions.

Since, the regular expressions are not fully supported in T-SQL you can implement them using CLR functions. Furthermore, you do not need any C# or CLR knowledge at all as all you need is already available in the MSDN String Utility Functions Sample.

In your case, the solution using regular expressions is:

SELECT [dbo].[RegexReplace] ([MyColumn], '(;.*)', '')
FROM [dbo].[MyTable]

But implementing such function in your database is going to help you solving more complex issues at all.

The example below shows how to deploy only the [dbo].[RegexReplace] function, but I will recommend to you to deploy the whole String Utility class.

1. Enabling CLR Integration. Execute the following Transact-SQL commands:

   sp_configure 'clr enabled', 1
   GO
   RECONFIGURE
   GO  
   

2. Bulding the code (or creating the .dll). Generraly, you can do this using the Visual Studio or .NET Framework command prompt (as it is shown in the article), but I prefer to use visual studio.

   • create new class library project:

     

   • copy and paste the following code in the Class1.cs file:

     using System;
     using System.IO;
     using System.Data.SqlTypes;
     using System.Text.RegularExpressions;
     using Microsoft.SqlServer.Server;
     
     public sealed class RegularExpression
     {
         public static string Replace(SqlString sqlInput, SqlString sqlPattern, SqlString sqlReplacement)
         {
             string input = (sqlInput.IsNull) ? string.Empty : sqlInput.Value;
             string pattern = (sqlPattern.IsNull) ? string.Empty : sqlPattern.Value;
             string replacement = (sqlReplacement.IsNull) ? string.Empty : sqlReplacement.Value;
             return Regex.Replace(input, pattern, replacement);
         }
     }
     

   • build the solution and get the path to the created .dll file:

     

   • replace the path to the .dll file in the following T-SQL statements and execute them:

     IF OBJECT_ID(N'RegexReplace', N'FS') is not null
     DROP Function RegexReplace;
     GO
     
     IF EXISTS (SELECT * FROM sys.assemblies WHERE [name] = 'StringUtils')
     DROP ASSEMBLY StringUtils;
     GO
     
     DECLARE @SamplePath nvarchar(1024)
     -- You will need to modify the value of the this variable if you have installed the sample someplace other than the default location.
     Set @SamplePath = 'C:\Users\gotqn\Desktop\StringUtils\StringUtils\StringUtils\bin\Debug\'
     CREATE ASSEMBLY [StringUtils] 
     FROM @SamplePath + 'StringUtils.dll'
     WITH permission_set = Safe;
     GO
     
     
     CREATE FUNCTION [RegexReplace] (@input nvarchar(max), @pattern nvarchar(max), @replacement nvarchar(max))
     RETURNS nvarchar(max)
     AS EXTERNAL NAME [StringUtils].[RegularExpression].[Replace]
     GO
     

   • That's it. Test your function:

     declare @MyTable table ([id] int primary key clustered, MyText varchar(100))
     insert into @MyTable ([id], MyText)
     select 1, 'some text; some more text'
     union all select 2, 'text again; even more text'
     union all select 3, 'text without a semicolon'
     union all select 4, null -- test NULLs
     union all select 5, '' -- test empty string
     union all select 6, 'test 3 semicolons; second part; third part'
     union all select 7, ';' -- test semicolon by itself    
     
     SELECT [dbo].[RegexReplace] ([MyText], '(;.*)', '')
     FROM @MyTable
     
     select * from @MyTable
     

If there is no existing method then I guess you can iterate from 0 to input.size()/2, taking each consecutive element and appending it to a new ArrayList.

EDIT: Actually, I think you can take that List and use it to instantiate a new ArrayList using one of the ArrayList constructors.

You should always try to use a composite object with concrete types (using composite design pattern) rather than a list of object types. Who would remember what the heck each of those objects is? Think about maintenance of your code later on... Instead, try something like this:

Public (Class or Structure) MyPerson
                public string FirstName { get; set; }
                public string LastName { get; set; }
                public string Address { get; set; }
                public int ZipCode { get; set; }
End Class

And then:

Dim person as new MyPerson With { .FirstName = “Joe”,
                                  .LastName = "Smith”,
                                  ...
                                 }
backgroundWorker1.RunWorkerAsync(person)

and then:

private void backgroundWorker1_DoWork (object sender, DoWorkEventArgs e)
{
        MyPerson person = e.Argument as MyPerson
        string firstname = person.FirstName;
        string lastname = person.LastName;
        int zipcode = person.ZipCode;                                 
}

Update (2020), Gyum Fox proposes https://regex101.com/r/U9Yqqg/2 (note regex101.com did not exist when I wrote originally this answer)

(\S+)=["']?((?:.(?!["']?\s+(?:\S+)=|\s*\/?[>"']))+.)["']?

Applied to:

<a href=test.html class=xyz>
<a href="test.html" class="xyz">
<a href='test.html' class="xyz">
<script type="text/javascript" defer async id="something" onload="alert('hello');"></script>
<img src="test.png">
<img src="a test.png">
<img src=test.png />
<img src=a test.png />
<img src=test.png >
<img src=a test.png >
<img src=test.png alt=crap >
<img src=a test.png alt=crap >

Original answer (2008): If you have an element like

<name attribute=value attribute="value" attribute='value'>

this regex could be used to find successively each attribute name and value

(\S+)=["']?((?:.(?!["']?\s+(?:\S+)=|[>"']))+.)["']?

Applied on:

<a href=test.html class=xyz>
<a href="test.html" class="xyz">
<a href='test.html' class="xyz">

it would yield:

'href' => 'test.html'
'class' => 'xyz'

Note: This does not work with numeric attribute values e.g. <div id="1"> won't work.

Edited: Improved regex for getting attributes with no value and values with " ' " inside.

([^\r\n\t\f\v= '"]+)(?:=(["'])?((?:.(?!\2?\s+(?:\S+)=|\2))+.)\2?)?

Applied on:

<script type="text/javascript" defer async id="something" onload="alert('hello');"></script>

it would yield:

'type' => 'text/javascript'
'defer' => ''
'async' => ''
'id' => 'something'
'onload' => 'alert(\'hello\');'

If you mean new E() then it is impossible. And I would add that it is not always correct - how do you know if E has public no-args constructor? But you can always delegate creation to some other class that knows how to create an instance - it can be Class<E> or your custom code like this

interface Factory<E>{
    E create();
}    

class IntegerFactory implements Factory<Integer>{    
  private static int i = 0; 
  Integer create() {        
    return i++;    
  }
}

An unusual but pretty way of doing it

Without index:

each _ in Array(5)
  = 'a'

Will print: aaaaa

With index:

each _, i in Array(5)
  = i

Will print: 01234

Notes: In the examples above, I have assigned the val parameter of jade's each iteration syntax to _ because it is required, but will always return undefined.

Since this is the first google hit for the problem and I assume more people will search for this. There is a new option since Spring Boot '1.4.0'. It is now possible to define a custom RequestMappingHandlerMapping that allows to define a different path for classes annotated with @RestController

A different version with custom annotations that combines @RestController with @RequestMapping can be found at this blog post

@Configuration
public class WebConfig {

    @Bean
    public WebMvcRegistrationsAdapter webMvcRegistrationsHandlerMapping() {
        return new WebMvcRegistrationsAdapter() {
            @Override
            public RequestMappingHandlerMapping getRequestMappingHandlerMapping() {
                return new RequestMappingHandlerMapping() {
                    private final static String API_BASE_PATH = "api";

                    @Override
                    protected void registerHandlerMethod(Object handler, Method method, RequestMappingInfo mapping) {
                        Class<?> beanType = method.getDeclaringClass();
                        if (AnnotationUtils.findAnnotation(beanType, RestController.class) != null) {
                            PatternsRequestCondition apiPattern = new PatternsRequestCondition(API_BASE_PATH)
                                    .combine(mapping.getPatternsCondition());

                            mapping = new RequestMappingInfo(mapping.getName(), apiPattern,
                                    mapping.getMethodsCondition(), mapping.getParamsCondition(),
                                    mapping.getHeadersCondition(), mapping.getConsumesCondition(),
                                    mapping.getProducesCondition(), mapping.getCustomCondition());
                        }

                        super.registerHandlerMethod(handler, method, mapping);
                    }
                };
            }
        };
    }
}

Try executing below command,

java -help

It gives option as,

-version print product version and exit

java -version is the correct command to execute

A good way with O(1) time complexity would be to use a max-heap. Call the heapify twice and you have the answer.

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

The above answer for webkit appearance worked, but the button still looked kind pale/dull compared to the browser on other devices/desktop. I also had to set opacity to full (ranges from 0 to 1)

-webkit-appearance:none;
opacity: 1

After setting the opacity, the button looked the same on all the different devices/emulator/desktop.

The Location directive system is

Like you want to forward all request which start /static and your data present in /var/www/static

So a simple method is separated last folder from full path , that means

Full path : /var/www/static

Last Path : /static and First path : /var/www

location <lastPath> {
    root <FirstPath>;
}

So lets see what you did mistake and what is your solutions

Your Mistake :

location /static {
    root /web/test.example.com/static;
}

Your Solutions :

location /static {
    root /web/test.example.com;
}

This excludes the final word instead of including it.

function smartTrim(str, length, delim, appendix) {
    if (str.length <= length) return str;

    var trimmedStr = str.substr(0, length+delim.length);

    var lastDelimIndex = trimmedStr.lastIndexOf(delim);
    if (lastDelimIndex >= 0) trimmedStr = trimmedStr.substr(0, lastDelimIndex);

    if (trimmedStr) trimmedStr += appendix;
    return trimmedStr;
}

Usage:

smartTrim(yourString, 11, ' ', ' ...')
"The quick ..."

Get a list with the desired values

small_letters = map(chr, range(ord('a'), ord('z')+1))
big_letters = map(chr, range(ord('A'), ord('Z')+1))
digits = map(chr, range(ord('0'), ord('9')+1))

or

import string
string.letters
string.uppercase
string.digits

This solution uses the ASCII table. ord gets the ascii value from a character and chr vice versa.

Apply what you know about lists

>>> small_letters = map(chr, range(ord('a'), ord('z')+1))

>>> an = small_letters[0:(ord('n')-ord('a')+1)]
>>> print(" ".join(an))
a b c d e f g h i j k l m n

>>> print(" ".join(small_letters[0::2]))
a c e g i k m o q s u w y

>>> s = small_letters[0:(ord('n')-ord('a')+1):2]
>>> print(" ".join(s))
a c e g i k m

>>> urls = ["hello.com/", "hej.com/", "hallo.com/"]
>>> print([x + y for x, y in zip(urls, an)])
['hello.com/a', 'hej.com/b', 'hallo.com/c']

You can use img.naturalWidth and img.naturalHeight to get real dimension of image in pixel

location ~* \.php$ {
    ...
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;    
}

Change default

fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

to

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

solved my problem.

At first, you must specify your path, the path that your *.csv files are in there

path = 'f:\project\dataset'

You can change it based on your system.

then,

use dir function :

files = dir (strcat(path,'\*.csv'))

L = length (files);

for i=1:L
   image{i}=csvread(strcat(path,'\',file(i).name));   
   % process the image in here
end

pwd also can be used.

I used the above logic but modified it slightly. My input is of format : "apple:100|pinapple:200|orange:300" stored in a variable @updtAdvanceKeyVal

Here is the function block :

set @res = "";

set @i = 1;
set @updtAdvanceKeyVal = updtAdvanceKeyVal;

REPEAT


 -- set r =  replace(SUBSTRING(SUBSTRING_INDEX(@updtAdvanceKeyVal, "|", @i),
 --  LENGTH(SUBSTRING_INDEX(@updtAdvanceKeyVal, "|", @i -1)) + 1),"|","");

-- wrapping the function in "replace" function as above causes to cut off a character from
 -- the 2nd splitted value if the value is more than 3 characters. Writing it in 2 lines causes no such problem and the output is as expected
-- sample output by executing the above function :
-- orange:100
-- pi apple:200    !!!!!!!!strange output!!!!!!!!
-- tomato:500

      set @r =  SUBSTRING(SUBSTRING_INDEX(@updtAdvanceKeyVal, "|", @i),
                  LENGTH(SUBSTRING_INDEX(@updtAdvanceKeyVal, "|", @i -1)) + 1);

      set @r = replace(@r,"|","");

      if @r <> "" then

              set @key = SUBSTRING_INDEX(@r, ":",1);
              set @val = SUBSTRING_INDEX(@r, ":",-1);

              select @key, @val;
      end if;

      set @i = @i + 1;

     until @r = ""
END REPEAT;

You can also close the application:

Application.Exit();

It will end the processes.

This happens because LatLngBounds() does not take two arbitrary points as parameters, but SW and NE points

use the .extend() method on an empty bounds object

var bounds = new google.maps.LatLngBounds();
bounds.extend(myPlace);
bounds.extend(Item_1);
map.fitBounds(bounds);

Modules are fine for storing enums and some global variables, constants and shared functions. its very good thing and I often use it. Declared variables are visible acros entire project.

Default user for MySQL is "root", and server "localhost".

Listing all the databases in mongoDB console is using the command show dbs.

For more information on this, refer the Mongo Shell Command Helpers that can be used in the mongo shell.

Another option is to use IO.FileInfo which gives you so much file info it make life easier just using this type:

PS > mkdir C:\Temp
PS > dir C:\Temp\
PS > [IO.FileInfo] $foo = 'C:\Temp\foo.txt'
PS > $foo.Exists
False
PS > New-TemporaryFile | Move-Item -Destination C:\Temp\foo.txt
PS > $foo.Refresh()
PS > $foo.Exists
True
PS > $foo | Select-Object *

You can give everybody execute permission:

GRANT Execute on [dbo].your_object to [public]

"Public" is the default database role that all users are a member of.

The above answers are right, but you have to make sure you input right URL.

You have to go to: https://developers.facebook.com/apps

1. Select your app
2. Click settings
3. Enter contact email (for publishing)
4. Click on +add platform
5. Add your platform (probably WEB)
6. Enter site URL

You have two choices to enter: http://www.example.com or http://example.com

Your app will work only with one of them. In order to make sure your visitors will use your desired url, use .htaccess on your domain.

Here's good tutorial on that: http://eppand.com/redirect-www-to-non-www-with-htaccess-file/

Enjoy!

],
[

  print_r($testArray);

  echo "<pre>";
  print_r($testArray);

To write a newline use \n not /n the latter is just a slash and a n

Here is how I found out a point on a circle with javascript, calculating the angle (degree) from the top of the circle.

  const centreX = 50; // centre x of circle
  const centreY = 50; // centre y of circle
  const r = 20; // radius
  const angleDeg = 45; // degree in angle from top
  const radians = angleDeg * (Math.PI/180);
  const pointY = centreY - (Math.cos(radians) * r); // specific point y on the circle for the angle
  const pointX = centreX + (Math.sin(radians) * r); // specific point x on the circle for the angle

Basically it boils down to using a fixed-width page and setting the width for those labels and controls. This is the most common way in which table-less layouts are implemented.

There are many ways to go about setting widths. Blueprint.css is a very popular css framework which can help you set up columns/widths.

Do this with a file stream. When a std::ofstream is closed, the file is created. I personally like the following code, because the OP only asks to create a file, not to write in it:

#include <fstream>

int main()
{
    std::ofstream file { "Hello.txt" };
    // Hello.txt has been created here
}

The temporary variable file is destroyed right after its creation, so the stream is closed and thus the file is created.

A tag is used to mark a version, more specifically it references a point in time on a branch. A branch is typically used to add features to a project.

I wanted to update or reset a value if it didn't quite validate, and ran into this problem.

The easy answer, ModelState.Remove, is.. problematic.. because if you are using helpers you don't really know the name (unless you stick by the naming convention). Unless perhaps you create a function that both your custom helper and your controller can use to get a name.

This feature should have been implemented as an option on the helper, where by default is does not do this, but if you wanted the unaccepted input to redisplay you could just say so.

But at least I understand the issue now ;).

To RUN press CtrlB (answer by matiit)

But when CtrlB does not work, Sublime Text probably can't find the Python Interpreter. When trying to run your program, see the log and find the reference to Python in path.

[cmd:  [u'python', u'-u', u'C:\\scripts\\test.py']]
[path: ...;C:\Python27 32bit;...]

The point is that it tries to run python via command line, the cmd looks like:

python -u C:\scripts\test.py

If you can't run python from cmd, Sublime Text can't too.
(Try it yourself in cmd, type python in it and run it, python commandline should appear)

SOLUTION

You can either change the Sublime Text build formula or the System %PATH%.

• To set your %PATH%:
  *You will need to restart your editor to load new %PATH%

  • Run Command Line* and enter this command: *needs to be run as administrator
    SETX /M PATH "%PATH%;<python_folder>"
    for example: SETX /M PATH "%PATH%;C:\Python27;C:\Python27\Scripts"

  • OR manually: (preferable)
    Add ;C:\Python27;C:\Python27\Scripts at the end of the string.

• To set the interpreter's path without messing with System %PATH% see this answer by ppy.

Go to angular.json file,

Search for keyword "serve":

Add port keyword as shown below:

 "serve": {
     "builder": "@angular-devkit/build-angular:dev-server",
     "options": {
         "browserTarget": "my-new-angular-app:build",
         "port": 3001
     },
     ...

They are both going to have the same effect.

However, as pointed out in the comments: $(window).scrollTop() is supported by more web browsers than $('html').scrollTop().

You can read the header by using the next() function which return the next row of the reader’s iterable object as a list. then you can add the content of the file to a list.

import csv
with open("C:/path/to/.filecsv", "rb") as f:
    reader = csv.reader(f)
    i = reader.next()
    rest = list(reader)

Now i has the column's names as a list.

print i
>>>['id', 'name', 'age', 'sex']

Also note that reader.next() does not work in python 3. Instead use the the inbuilt next() to get the first line of the csv immediately after reading like so:

import csv
with open("C:/path/to/.filecsv", "rb") as f:
    reader = csv.reader(f)
    i = next(reader)

    print(i)
    >>>['id', 'name', 'age', 'sex']

You can use below code snippet

import shlex
import subprocess
import json

def call_curl(curl):
    args = shlex.split(curl)
    process = subprocess.Popen(args, shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    stdout, stderr = process.communicate()
    return json.loads(stdout.decode('utf-8'))


if __name__ == '__main__':
    curl = '''curl - X
    POST - d
    '{"nw_src": "10.0.0.1/32", "nw_dst": "10.0.0.2/32", "nw_proto": "ICMP", "actions": "ALLOW", "priority": "10"}'
    http: // localhost: 8080 / firewall / rules / 0000000000000001 '''
    output = call_curl(curl)
    print(output)

It should work - as long as the data variable is actually an array containing a dictionary with the key SPORT

NSArray *data = [NSArray arrayWithObject:[NSMutableDictionary dictionaryWithObject:@"foo" forKey:@"BAR"]];    
NSArray *filtered = [data filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"(BAR == %@)", @"foo"]];

Filtered in this case contains the dictionary.

(the %@ does not have to be quoted, this is done when NSPredicate creates the object.)

Go to the appropriate subdirectory of the EDQP Tomcat installation directory. The default directories are:

On Linux: /opt/server/tomcat/bin

On Windows: c:\server\tomcat\bin

On Linux: ./startup.sh

On Windows: % startup.bat

Run the shutdown command:

On Linux: ./shutdown.sh

Just like you do for getting something from the CNode you also need to do for the ANode

XmlNodeList xnList = xml.SelectNodes("/Element[@*]");
foreach (XmlNode xn in xnList)
{
  XmlNode anode = xn.SelectSingleNode("ANode");
    if (anode!= null)
    {
        string id = anode["ID"].InnerText;
        string date = anode["Date"].InnerText;
        XmlNodeList CNodes = xn.SelectNodes("ANode/BNode/CNode");
        foreach (XmlNode node in CNodes)
        {
         XmlNode example = node.SelectSingleNode("Example");
         if (example != null)
         {
            string na = example["Name"].InnerText;
            string no = example["NO"].InnerText;
         }
        }
    }
}

As of January 2020 and Xcode 11.3.1 -

• Open Xcode
• Open Xcode Preferences (Xcode->Preferences or Cmd-,)
• Click on Accounts
• At the left, click on your developer ID
• At the bottom right, click on Manage Certificates...
• In the lower left corner, click the arrow to the right of the + (plus)
• Select Apple Distribution from the menu

Xcode will automatically create an Apple Distribution certificate, install it in Keychain Access, and update Xcode's signing information

(Note: the single Apple Distribution certificate is now provided instead of the previous iOS Distribution certificate and equivalents.)

subprocess.Popen creates a process and opens pipes and stuff. What you are doing is:

• Start a process sudo -S
• Start a process mypass
• Start a process mount -t vboxsf myfolder /home/myuser/myfolder

which is obviously not going to work. You need to pass the arguments to Popen. If you look at its documentation, you will notice that the first argument is actually a list of the arguments.

You need to set the error mode attribute PDO::ATTR_ERRMODE to PDO::ERRMODE_EXCEPTION.
And since you expect the exception to be thrown by the prepare() method you should disable the PDO::ATTR_EMULATE_PREPARES* feature. Otherwise the MySQL server doesn't "see" the statement until it's executed.

<?php
try {
    $pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);


    $pdo->prepare('INSERT INTO DoesNotExist (x) VALUES (?)');
}
catch(Exception $e) {
    echo 'Exception -> ';
    var_dump($e->getMessage());
}

prints (in my case)

Exception -> string(91) "SQLSTATE[42S02]: Base table or view not found: 
1146 Table 'test.doesnotexist' doesn't exist"

see http://wezfurlong.org/blog/2006/apr/using-pdo-mysql/
EMULATE_PREPARES=true seems to be the default setting for the pdo_mysql driver right now. The query cache thing has been fixed/change since then and with the mysqlnd driver I hadn't problems with EMULATE_PREPARES=false (though I'm only a php hobbyist, don't take my word on it...)

*) and then there's PDO::MYSQL_ATTR_DIRECT_QUERY - I must admit that I don't understand the interaction of those two attributes (yet?), so I set them both, like

$pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly', array(
    PDO::ATTR_EMULATE_PREPARES=>false,
    PDO::MYSQL_ATTR_DIRECT_QUERY=>false,
    PDO::ATTR_ERRMODE=>PDO::ERRMODE_EXCEPTION
));

In node.js you can also do the following:

const { promisify } = require('util')
const delay = promisify(setTimeout)

delay(1000).then(() => console.log('hello'))

Method call setSelectedIndex("item_value"); doesn't work because setSelectedIndex use sequential index.

.so files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.

.a files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar command -- a predecessor of tar that's now just used for making libraries) of the original .o object files.

.la files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?

Static and dynamic libraries each have pros and cons.

Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.

Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.

Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.

Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.

Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.

Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.

Dynamic libraries are especially useful for system libraries, like libc. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.

Oracle. Thanks to this post PL/SQL - Use "List" Variable in Where In Clause

I put together my example statement to easily manually input values (being reused in testing an application by testers):

WITH prods AS (
    SELECT column_value AS prods_code 
    FROM TABLE(
        sys.odcivarchar2list(
            'prod1', 
            'prod2'
        )
    )
)
SELECT * FROM prods

Consider TextArea

People finding this via Google and looking for a better way to manage the display of their snippets should also consider <textarea> which gives a lot of control over width/height, scrolling etc. Noting that @vsync mentioned the deprecated tag <xmp>, I find <textarea readonly> is an excellent substitute for displaying HTML without the need to escape anything inside it (except where </textarea> might appear within).

For example, to display a single line with controlled line wrapping, consider <textarea rows=1 cols=100 readonly> your html or etc with any characters including tabs and CrLf's </textarea>.

<textarea rows=5 cols=100 readonly>Example text with Newlines,_x000D_
tabs & space,_x000D_
  html tags etc <b>displayed</b>._x000D_
    However, note that &amp; still acts as an escape char.._x000D_
      Eg: &lt;u&gt;(text)&lt;/u&gt;_x000D_
</textarea>

this is commonly known as nesting iterators into other iterators I think

The code you have posted here and code on your site both are different. There is a break <br> after second image, so the third image into new line, remove this <br> and it will display correctly.

You should be able to use CSS (http://docs.jquery.com/CSS/css#name). You may have to be more specific such as "padding-left" or "margin-top".

Example:

CSS

a, a:link, a:hover, a:visited, a:active {color:black;margin-top:10px;text-decoration: none;}

JS

$("a").css("margin-top");

The result is 10px.

If you want to get the integer value, you can do the following:

parseInt($("a").css("margin-top"))

We modify a Meouw function to be used with keyup, because when you are using an input it can be more helpful.

Check this:

Hey there!, @heridev and I created a small function in jQuery.

You can try next:

HTML

<input type="text" name="one" class="two-digits"><br>
<input type="text" name="two" class="two-digits">?

jQuery

// apply the two-digits behaviour to elements with 'two-digits' as their class
$( function() {
    $('.two-digits').keyup(function(){
        if($(this).val().indexOf('.')!=-1){         
            if($(this).val().split(".")[1].length > 2){                
                if( isNaN( parseFloat( this.value ) ) ) return;
                this.value = parseFloat(this.value).toFixed(2);
            }  
         }            
         return this; //for chaining

Swift 4.2 Extension method

extension UIImage {
    func toBase64() -> String? {
        guard let imageData = self.pngData() else { return nil }
        return imageData.base64EncodedString(options: Data.Base64EncodingOptions.lineLength64Characters)
    }
}

XCode 9.1 and Swift 4.0

//
// Convert UIImage to a base64 representation
//
class func convertImageToBase64(image: UIImage) -> String {
    let imageData = UIImagePNGRepresentation(image)!

Even though there are already many many answers to this post, I feel I have to add another option for unix hosts that only returns the sum of all file sizes in the directory (recursively).

If you look at Jonathan's answer he uses the du command. This command will return the total directory size but the pure PHP solutions posted by others here will return the sum of all file sizes. Big difference!

What to look out for

When running du on a newly created directory, it may return 4K instead of 0. This may even get more confusing after having deleted files from the directory in question, having du reporting a total directory size that does not correspond to the sum of the sizes of the files within it. Why? The command du returns a report based on some file settings, as Hermann Ingjaldsson commented on this post.

The solution

To form a solution that behaves like some of the PHP-only scripts posted here, you can use ls command and pipe it to awk like this:

ls -ltrR /path/to/dir |awk '{print \$5}'|awk 'BEGIN{sum=0} {sum=sum+\$1} END {print sum}'

As a PHP function you could use something like this:

function getDirectorySize( $path )
{
    if( !is_dir( $path ) ) {
        return 0;
    }

    $path   = strval( $path );
    $io     = popen( "ls -ltrR {$path} |awk '{print \$5}'|awk 'BEGIN{sum=0} {sum=sum+\$1} END {print sum}'", 'r' );
    $size   = intval( fgets( $io, 80 ) );
    pclose( $io );

    return $size;
}

When you push a new branch the first time use: >git push -u origin

After that, you can just type a shorter command: >git push

The first-time -u option created a persistent upstream tracking branch with your local branch.

Insert a 3rd column and in Cell C2 paste this formula

=IF(SUMPRODUCT(($A$2:$A2=A2)*($B$2:$B2=B2))>1,0,1)

and copy it down. Now create your pivot based on 1st and 3rd column. See snapshot

add this at the top of file,

header('content-type: application/json; charset=utf-8');
header("access-control-allow-origin: *");

Here's my efficient approach for displaying 2-D integer array using a StringBuilder array.

public static void printMatrix(int[][] arr) {
    if (null == arr || arr.length == 0) {
        // empty or null matrix
        return;
    }

    int idx = -1;
    StringBuilder[] sbArr = new StringBuilder[arr.length];

    for (int[] row : arr) {
        sbArr[++idx] = new StringBuilder("(\t");

        for (int elem : row) {
            sbArr[idx].append(elem + "\t");
        }

        sbArr[idx].append(")");
    }

    for (int i = 0; i < sbArr.length; i++) {
        System.out.println(sbArr[i]);
    }
    System.out.println("\nDONE\n");
}

Execute this at the terminal to see conflicting configurations listening to the same port:

grep -R default_server /etc/nginx

The above solutions suggesting the use of regex aren't ideal because this is such a small task and regex requires more resource overhead than the simplicity of the task justifies.

Here's what I do:

myString = myString.replace(' ', '').replace('\t', '').replace('\n', '')

or if you had a bunch of things to remove such that a single line solution would be gratuitously long:

removal_list = [' ', '\t', '\n']
for s in removal_list:
  myString = myString.replace(s, '')

The simplest way: run git push -u origin feature/123-sandbox-tests once. That pushes the branch the way you're used to doing it and also sets the upstream tracking info in your local config. After that, you can just git push to push tracked branches to their upstream remote(s).

You can also do this in the config yourself by setting branch.<branch name>.merge to the remote branch name (in your case the same as the local name) and optionally, branch.<branch name>.remote to the name of the remote you want to push to (defaults to origin). If you look in your config, there's most likely already one of these set for master, so you can follow that example.

Finally, make sure you consider the push.default setting. It defaults to "matching", which can have undesired and unexpected results. Most people I know find "upstream" more intuitive, which pushes only the current branch.

Details on each of these settings can be found in the git-config man page.

On second thought, on re-reading your question, I think you know all this. I think what you're actually looking for doesn't exist. How about a bash function something like (untested):

function pushCurrent {
  git config push.default upstream
  git push
  git config push.default matching
}

Based off your code, i created this Fiddle
You need to use

var cb = document.getElementsByName('field206451')[0];
var label = document.getElementsByName('label206451')[0];

if you want to use name attributes then you have to take the index since it is a list of items, not just a single one. Everything else worked good.

Most likely, you ran out of memory, so the Kernel killed your process.

Have you heard about OOM Killer?

Here's a log from a script that I developed for processing a huge set of data from CSV files:

Mar 12 18:20:38 server.com kernel: [63802.396693] Out of memory: Kill process 12216 (python3) score 915 or sacrifice child
Mar 12 18:20:38 server.com kernel: [63802.402542] Killed process 12216 (python3) total-vm:9695784kB, anon-rss:7623168kB, file-rss:4kB, shmem-rss:0kB
Mar 12 18:20:38 server.com kernel: [63803.002121] oom_reaper: reaped process 12216 (python3), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB

It was taken from /var/log/syslog.

Basically:

PID 12216 elected as a victim (due to its use of +9Gb of total-vm), so oom_killer reaped it.

Here's a article about OOM behavior.

So if you want to build your SVG stuff piece by piece in JS, then don't just use createElement(), those won't draw, use this instead:

var ci = document.createElementNS("http://www.w3.org/2000/svg", "circle");

//go through this code I have made several changes in it//

import java.util.Scanner;

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

//declare arrays

String [] contactPhone = new String [12];
String [] contactAdd1 = new String [12];
String [] contactAdd2 = new String [12];
int i=0;
String name = "0";
String phone = "0";
String add1 = "0";
String add2 = "0";
//method of taken input
Scanner input = new Scanner(System.in);

//while name field is empty display prompt etc.
while (i<11)
{
    i++;
System.out.println("Enter contacts name: "+ i);
name = input.nextLine();
name += contactName[i];
}


while (i<12)
{
    i++;
System.out.println("Enter contacts addressline1:");
add1 = input.nextLine();
add1 += contactAdd1[i];
}

while (i<12)

System.out.println("Enter contact phone number: ");
phone = input.nextLine();
phone += contactPhone[i];
}

Here is the code that works for me. The key is that you need a wrapper class.

public class Person {

    private String name;
    private Integer age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "Person [name=" + name + ", age=" + age + "]";
    }

A PersonWrapper class

public class PersonWrapper {

    private List<Person> persons;

    /**
     * @return the persons
     */
    public List<Person> getPersons() {
        return persons;
    }

    /**
     * @param persons the persons to set
     */
    public void setPersons(List<Person> persons) {
        this.persons = persons;
    }
}

My Controller methods

@RequestMapping(value="person", method=RequestMethod.POST,consumes="application/json",produces="application/json")
    @ResponseBody
    public List<String> savePerson(@RequestBody PersonWrapper wrapper) {
        List<String> response = new ArrayList<String>();
        for (Person person: wrapper.getPersons()){
        personService.save(person);
         response.add("Saved person: " + person.toString());
    }
        return response;
    }

The request sent is json in POST

{"persons":[{"name":"shail1","age":"2"},{"name":"shail2","age":"3"}]}

And the response is

["Saved person: Person [name=shail1, age=2]","Saved person: Person [name=shail2, age=3]"]

I know it's been said already, but I'd highly recommend the requests Python package.

If you've used languages other than python, you're probably thinking urllib and urllib2 are easy to use, not much code, and highly capable, that's how I used to think. But the requests package is so unbelievably useful and short that everyone should be using it.

First, it supports a fully restful API, and is as easy as:

import requests

resp = requests.get('http://www.mywebsite.com/user')
resp = requests.post('http://www.mywebsite.com/user')
resp = requests.put('http://www.mywebsite.com/user/put')
resp = requests.delete('http://www.mywebsite.com/user/delete')

Regardless of whether GET / POST, you never have to encode parameters again, it simply takes a dictionary as an argument and is good to go:

userdata = {"firstname": "John", "lastname": "Doe", "password": "jdoe123"}
resp = requests.post('http://www.mywebsite.com/user', data=userdata)

Plus it even has a built in JSON decoder (again, I know json.loads() isn't a lot more to write, but this sure is convenient):

resp.json()

Or if your response data is just text, use:

resp.text

This is just the tip of the iceberg. This is the list of features from the requests site:

• International Domains and URLs
• Keep-Alive & Connection Pooling
• Sessions with Cookie Persistence
• Browser-style SSL Verification
• Basic/Digest Authentication
• Elegant Key/Value Cookies
• Automatic Decompression
• Unicode Response Bodies
• Multipart File Uploads
• Connection Timeouts
• .netrc support
• List item
• Python 2.6—3.4
• Thread-safe.

In XML 1.0, the XML Declaration is optional. See section 2.8 of the XML 1.0 Recommendation, where it says it "should" be used -- which means it is recommended, but not mandatory. In XML 1.1, however, the declaration is mandatory. See section 2.8 of the XML 1.1 Recommendation, where it says "MUST" be used. It even goes on to state that if the declaration is absent, that automatically implies the document is an XML 1.0 document.

Note that in an XML Declaration the encoding and standalone are both optional. Only the version is mandatory. Also, these are not attributes, so if they are present they must be in that order: version, followed by any encoding, followed by any standalone.

<?xml version="1.0"?>
<?xml version="1.0" encoding="UTF-8"?>
<?xml version="1.0" standalone="yes"?>
<?xml version="1.0" encoding="UTF-16" standalone="yes"?>

If you don't specify the encoding in this way, XML parsers try to guess what encoding is being used. The XML 1.0 Recommendation describes one possible way character encoding can be autodetected. In practice, this is not much of a problem if the input is encoded as UTF-8, UTF-16 or US-ASCII. Autodetection doesn't work when it encounters 8-bit encodings that use characters outside the US-ASCII range (e.g. ISO 8859-1) -- avoid creating these if you can.

The standalone indicates whether the XML document can be correctly processed without the DTD or not. People rarely use it. These days, it is a bad to design an XML format that is missing information without its DTD.

Update:

A "prolog error/invalid utf-8 encoding" error indicates that the actual data the parser found inside the file did not match the encoding that the XML declaration says it is. Or in some cases the data inside the file did not match the autodetected encoding.

Since your file contains a byte-order-mark (BOM) it should be in UTF-16 encoding. I suspect that your declaration says <?xml version="1.0" encoding="UTF-8"?> which is obviously incorrect when the file has been changed into UTF-16 by NotePad. The simple solution is to remove the encoding and simply say <?xml version="1.0"?>. You could also edit it to say encoding="UTF-16" but that would be wrong for the original file (which wasn't in UTF-16) or if the file somehow gets changed back to UTF-8 or some other encoding.

Don't bother trying to remove the BOM -- that's not the cause of the problem. Using NotePad or WordPad to edit XML is the real problem!

in IIS, highlight the machine, double-click "Request Filtering", open the "Hidden Segments" tab. "App_Data" is listed there as a restricted folder. Yes i know this thread is really old, but this is still applicable.

From LDAP, there is not a query method to determine an empty string.

The best practice would be to scrub your data inputs to LDAP as an empty or null value in LDAP is no value at all.

To determine this you would need to query for all with a value (manager=*) and then use code to determine the ones that were a "space" or null value.

And as Terry said, storing an empty or null value in an attribute of DN syntax is wrong.

Some LDAP server implementations will not permit entering a DN where the DN entry does not exist.

Perhaps, you could, if your DN's are consistent, use something like:

(&(!(manager=cn*))(manager=*))

This should return any value of manager where there was a value for manager and it did not start with "cn".

However, some LDAP implementations will not allow sub-string searches on DN syntax attributes.

If you've downloaded SQL from the Microsoft site, rename the file to a zip file and then you can extract the files inside to a folder, then choose that one when you "Browse for SQL server Installation Media"

SQLEXPRADV_x64_ENU.exe > SQLEXPRADV_x64_ENU.zip

7zip will open it (standard Windows zip doesn't work though)

Extract to something like C:\SQLInstallMedia

You will get folders like 1033_enu_lp, resources, x64 and a bunch of files.

The main() method is the entry point for a Java application. run() is typically used for new threads or tasks.

Where have you been writing a run() method, what kind of application are you writing (e.g. Swing, AWT, console etc) and what's your development environment?

you can determine am or pm with this simple code

var today=new Date();
var noon=new Date(today.getFullYear(),today.getMonth(),today.getDate(),12,0,0);
var ampm = (today.getTime()<noon.getTime())?'am':'pm';

I'm doing a git repository statistics generator in ruby, it's called git_stats.

You can find examples generated for some repositories on project page.

Here is a list of what it can do:

• General statistics
  • Total files (text and binary)
  • Total lines (added and deleted)
  • Total commits
  • Authors
• Activity (total and per author)
  • Commits by date
  • Commits by hour of day
  • Commits by day of week
  • Commits by hour of week
  • Commits by month of year
  • Commits by year
  • Commits by year and month
• Authors
  • Commits by author
  • Lines added by author
  • Lines deleted by author
  • Lines changed by author
• Files and lines
  • By date
  • By extension

If you have any idea what to add or improve please let me know, I would appreciate any feedback.

You can use the 'attributes' method:

@car.attributes = {:model => 'Sierra', :years => '1990', :looks => 'Sexy'}

Source: http://api.rubyonrails.org/classes/ActiveRecord/Base.html

attributes=(new_attributes, guard_protected_attributes = true) Allows you to set all the attributes at once by passing in a hash with keys matching the attribute names (which again matches the column names).

If guard_protected_attributes is true (the default), then sensitive attributes can be protected from this form of mass-assignment by using the attr_protected macro. Or you can alternatively specify which attributes can be accessed with the attr_accessible macro. Then all the attributes not included in that won’t be allowed to be mass-assigned.

class User < ActiveRecord::Base
  attr_protected :is_admin
end

user = User.new
user.attributes = { :username => 'Phusion', :is_admin => true }
user.username   # => "Phusion"
user.is_admin?  # => false

user.send(:attributes=, { :username => 'Phusion', :is_admin => true }, false)
user.is_admin?  # => true

I don't see anywhere in the code where you specify that this is a POST request. Then again, you need a java.net.HttpURLConnection to do that.

In fact, I highly recommend using HttpURLConnection instead of URLConnection, with conn.setRequestMethod("POST"); and see if it still gives you problems.

OK,

Here's a dinosaur method for you on Office 2010.

Write the full address you want using concatenate (the "&" method of combining text).

Do this for all the addresses you need. It should look like:

="="&"'\FULL NETWORK ADDRESS including [Spreadsheet Name]"&W3&"'!$w4"

The W3 is a dynamic reference to what sheet I am using, the W4 is the cell I want to get from the sheet.

Once you have this, start up a macro recording session. Copy the cell and paste it into another. I pasted it into a merged cell and it gave me the classic "Same size" error. But one thing it did was paste the resulting text from my concatenate (including that extra "=").

Copy over however many you did this for. Then, go into each pasted cell, select he text and just hit enter. It updates it to an active direct reference.

Once you have finished, put the cursor somewhere nice and stop the macro. Assign it to a button and you are done.

It is a bit of a PITA to do this the first time, but once you have done it, you have just made the square peg fit that daamned round hole.

This is working Oracle example but it should work in MySQL too.

You are missing smth - see IN after END Replace 'IN' with '=' sign for a single value.

SELECT empno, ename, job
  FROM scott.emp
 WHERE (CASE WHEN job = 'MANAGER' THEN '1'  
         WHEN job = 'CLERK'   THEN '2' 
         ELSE '0'  END) IN (1, 2)

android.widget.Button.setOnClickListener(android.view.View$OnClickListener)' on a null object reference

Because Submit button is inside login_modal so you need to use loginDialog view to access button:

Submit = (Button)loginDialog.findViewById(R.id.Submit);

Going through the answers there are some details missing regarding `Cascade' and id generation. See question

Also, it is worth mentioning that you can have separate Cascade annotations for merging and persisting: Cascade.MERGE and Cascade.PERSIST which will be treated according to the used method.

The spec is your friend ;)

This will go through the source directory, create any directories that do not already exist in destination directory, and move files from source to the destination directory:

import os
import shutil

root_src_dir = 'Src Directory\\'
root_dst_dir = 'Dst Directory\\'

for src_dir, dirs, files in os.walk(root_src_dir):
    dst_dir = src_dir.replace(root_src_dir, root_dst_dir, 1)
    if not os.path.exists(dst_dir):
        os.makedirs(dst_dir)
    for file_ in files:
        src_file = os.path.join(src_dir, file_)
        dst_file = os.path.join(dst_dir, file_)
        if os.path.exists(dst_file):
            # in case of the src and dst are the same file
            if os.path.samefile(src_file, dst_file):
                continue
            os.remove(dst_file)
        shutil.move(src_file, dst_dir)

Any pre-existing files will be removed first (via os.remove) before being replace by the corresponding source file. Any files or directories that already exist in the destination but not in the source will remain untouched.

Tom's answer is quite detailed and exhaustive but you may also be interested in this simple study about Parquet vs Avro done at Allstate Insurance, summarized here:

"Overall, Parquet showed either similar or better results on every test [than Avro]. The query-performance differences on the larger datasets in Parquet’s favor are partly due to the compression results; when querying the wide dataset, Spark had to read 3.5x less data for Parquet than Avro. Avro did not perform well when processing the entire dataset, as suspected."

Very good answer using inheritance, just remember to override the initializer

public class Utf8StringWriter : StringWriter
{
    public Utf8StringWriter(StringBuilder sb) : base (sb)
    {
    }
    public override Encoding Encoding { get { return Encoding.UTF8; } }
}

Just create a new array in your dictionary

Dictionary<string, List<string>> myDic = new Dictionary<string, List<string>>();
myDic.Add(newKey, new List<string>(existingList));

Just a mention with jQuery v3.2.1 and Laravel 5.6.

Case 1: The JS object posted directly, like:

$.post("url", {name:'John'}, function( data ) {
});

Corresponding Laravel PHP code should be:

parse_str($request->getContent(),$data); //JSON will be parsed to object $data

Case 2: The JSON string posted, like:

$.post("url", JSON.stringify({name:'John'}), function( data ) {
});

Corresponding Laravel PHP code should be:

$data = json_decode($request->getContent(), true);

If you use Eclipse as your IDE I would recommend the excellent eclipse plugin memory analyzer

Another option is to use JVisualVM, it can read (and create) heap dumps as well, and is shipped with every JDK. You can find it in the bin directory of your JDK.

To center it, you can use the technique shown here: Absolute centering.

To make it as big as possible, give it max-width and max-height of 100%.

To maintain the aspect ratio (even when the width is specifically set like in the snippet below), use object-fit as explained here.

.className {
    max-width: 100%;
    max-height: 100%;
    bottom: 0;
    left: 0;
    margin: auto;
    overflow: auto;
    position: fixed;
    right: 0;
    top: 0;
    -o-object-fit: contain;
    object-fit: contain;
}

<img src="https://i.imgur.com/HmezgW6.png" class="className" />

<!-- Slider to control the image width, only to make demo clearer !-->
<input type="range" min="10" max="2000" value="276" step="10" oninput="document.querySelector('img').style.width = (this.value +'px')" style="width: 90%; position: absolute; z-index: 2;" >

This answer is similar to @PaulMcG's answer but doesn't require sorting the input.

For those into functional programming, groupBy can be written in one line (not including imports!), and unlike itertools.groupby it doesn't require the input to be sorted:

from functools import reduce # import needed for python3; builtin in python2
from collections import defaultdict

def groupBy(key, seq):
 return reduce(lambda grp, val: grp[key(val)].append(val) or grp, seq, defaultdict(list))

(The reason for ... or grp in the lambda is that for this reduce() to work, the lambda needs to return its first argument; because list.append() always returns None the or will always return grp. I.e. it's a hack to get around python's restriction that a lambda can only evaluate a single expression.)

This returns a dict whose keys are found by evaluating the given function and whose values are a list of the original items in the original order. For the OP's example, calling this as groupBy(lambda pair: pair[1], input) will return this dict:

{'KAT': [('11013331', 'KAT'), ('9843236', 'KAT')],
 'NOT': [('9085267', 'NOT'), ('11788544', 'NOT')],
 'ETH': [('5238761', 'ETH'), ('5349618', 'ETH'), ('962142', 'ETH'), ('7795297', 'ETH'), ('7341464', 'ETH'), ('5594916', 'ETH'), ('1550003', 'ETH')]}

And as per @PaulMcG's answer the OP's requested format can be found by wrapping that in a list comprehension. So this will do it:

result = {key: [pair[0] for pair in values],
          for key, values in groupBy(lambda pair: pair[1], input).items()}

For anyone who works in VB.NET

Try
Catch ex As DbEntityValidationException
    For Each a In ex.EntityValidationErrors
        For Each b In a.ValidationErrors
            Dim st1 As String = b.PropertyName
            Dim st2 As String = b.ErrorMessage
        Next
    Next
End Try

After that, Click Apply and OK.

Use the display: inline CSS property.

Ideal: In the stylesheet:

#container p { display: inline }

Bad/Extreme situation: Inline:

<p style="display:inline">...</p>

You could return Enumerable.Empty<T>().

If using JavaScript is an option and you want to avoid nesting tables, include jQuery and try the following method.

First, you'll have to give each row a unique id like so:

<table>
  <tr id="idrow1"><td> ADD AS MANY COLUMNS AS YOU LIKE  </td><td><button onclick="submitRowAsForm('idrow1')">SUBMIT ROW1</button></td></tr>
  <tr id="idrow2"><td> PUT INPUT FIELDS IN THE COLUMNS  </td><td><button onclick="submitRowAsForm('idrow2')">SUBMIT ROW2</button></td></tr>
  <tr id="idrow3"><td>ADD MORE THAN ONE INPUT PER COLUMN</td><td><button onclick="submitRowAsForm('idrow3')">SUBMIT ROW3</button></td></tr>
</table>

Then, include the following function in your JavaScript for your page.

<script>
function submitRowAsForm(idRow) {
  form = document.createElement("form"); // CREATE A NEW FORM TO DUMP ELEMENTS INTO FOR SUBMISSION
  form.method = "post"; // CHOOSE FORM SUBMISSION METHOD, "GET" OR "POST"
  form.action = ""; // TELL THE FORM WHAT PAGE TO SUBMIT TO
  $("#"+idRow+" td").children().each(function() { // GRAB ALL CHILD ELEMENTS OF <TD>'S IN THE ROW IDENTIFIED BY idRow, CLONE THEM, AND DUMP THEM IN OUR FORM
        if(this.type.substring(0,6) == "select") { // JQUERY DOESN'T CLONE <SELECT> ELEMENTS PROPERLY, SO HANDLE THAT
            input = document.createElement("input"); // CREATE AN ELEMENT TO COPY VALUES TO
            input.type = "hidden";
            input.name = this.name; // GIVE ELEMENT SAME NAME AS THE <SELECT>
            input.value = this.value; // ASSIGN THE VALUE FROM THE <SELECT>
            form.appendChild(input);
        } else { // IF IT'S NOT A SELECT ELEMENT, JUST CLONE IT.
            $(this).clone().appendTo(form);
        }

    });
  form.submit(); // NOW SUBMIT THE FORM THAT WE'VE JUST CREATED AND POPULATED
}
</script>

So what have we done here? We've given each row a unique id and included an element in the row that can trigger the submission of that row's unique identifier. When the submission element is activated, a new form is dynamically created and set up. Then using jQuery, we clone all of the elements contained in <td>'s of the row that we were passed and append the clones to our dynamically created form. Finally, we submit said form.

You can try this too:

public class Match
{
    [Key]
    public int MatchId { get; set; }

    [ForeignKey("HomeTeam"), Column(Order = 0)]
    public int? HomeTeamId { get; set; }
    [ForeignKey("GuestTeam"), Column(Order = 1)]
    public int? GuestTeamId { get; set; }

    public float HomePoints { get; set; }
    public float GuestPoints { get; set; }
    public DateTime Date { get; set; }

    public virtual Team HomeTeam { get; set; }
    public virtual Team GuestTeam { get; set; }
}

When you make a FK column allow NULLS, you are breaking the cycle. Or we are just cheating the EF schema generator.

In my case, this simple modification solve the problem.

For relative imports you have to:

• a) use relative name

• b) provide anchor explicitly

  importlib.import_module('.c', 'a.b')
  

Of course, you could also just do absolute import instead:

importlib.import_module('a.b.c')

Well what I did was remove the gutter between the respective spans then drawing a left border for the left span and a right border for the right span in such a way that their borders overlapped just to give a single line. This way the visible line will just be one of borders.

Try this it works for me

Try this, if your input is string 
For example 

string input= "13:01";
string[] arry = input.Split(':');                  
string timeinput = arry[0] + arry[1];
private string Convert24To12HourInEnglish(string timeinput)

 {

DateTime startTime = new DateTime(2018, 1, 1, int.Parse(timeinput.Substring(0, 2)), 
int.Parse(timeinput.Substring(2, 2)), 0); 
return startTime.ToString("hh:mm tt");

}
out put: 01:01

I struggle with this problem. In my case I wasn't importing the right @Test annotation.

1) Check if the @Test is from org.junit.jupiter.api.Test (if you are using Junit 5).

2) With Junit5 instead of @RunWith(SpringRunner.class), use @ExtendWith(SpringExtension.class)

import org.junit.jupiter.api.Test;

@ExtendWith(SpringExtension.class)
@SpringBootTest
@AutoConfigureMockMvc
@TestPropertySource(locations = "classpath:application.properties")    
public class CotacaoTest {
    @Test
    public void testXXX() {

    }
}

Simply in one line:

var result = table.First(x => x.Status == table.Max(y => y.Status));

Notice that there are two action. the inner action is for finding the max value, the outer action is for get the desired object.

You can do it in a few lines, just override onPostExecute when you call your AsyncTask. Here is an example for you:

new AasyncTask()
{
    @Override public void onPostExecute(String result)
    {
       // do whatever you want with result 
    }
}.execute(a.targetServer);

I hope it helped you, happy codding :)

For simple integer arithmetic, you can also use the builtin let command.

 ONE=1
 TWO=2
 let "THREE = $ONE + $TWO"
 echo $THREE
    3

For more info on let, look here.

        int arrEmpty[] = new int[] {};
        Assert.assertEquals(PrintPermutation.permutation(arrEmpty), 0);
    }
}

Yes it is possible to call one constructor from another. But there is a rule to it. If a call is made from one constructor to another, then

that new constructor call must be the first statement in the current constructor

public class Product {
     private int productId;
     private String productName;
     private double productPrice;
     private String category;

    public Product(int id, String name) {
        this(id,name,1.0);
    }

    public Product(int id, String name, double price) {
        this(id,name,price,"DEFAULT");
    }

    public Product(int id,String name,double price, String category){
        this.productId=id;
        this.productName=name;
        this.productPrice=price;
        this.category=category;
    }
}

So, something like below will not work.

public Product(int id, String name, double price) {
    System.out.println("Calling constructor with price");
    this(id,name,price,"DEFAULT");
}

Also, in the case of inheritance, when sub-class's object is created, the super class constructor is first called.

public class SuperClass {
    public SuperClass() {
       System.out.println("Inside super class constructor");
    }
}
public class SubClass extends SuperClass {
    public SubClass () {
       //Even if we do not add, Java adds the call to super class's constructor like 
       // super();
       System.out.println("Inside sub class constructor");
    }
}

Thus, in this case also another constructor call is first declared before any other statements.

Instance variable is the variable declared inside a class, but outside a method: something like:

class IronMan {

    /** These are all instance variables **/
    public String realName;
    public String[] superPowers;
    public int age;

    /** Getters and setters here **/
}

Now this IronMan Class can be instantiated in another class to use these variables. Something like:

class Avengers {

    public static void main(String[] a) {
        IronMan ironman = new IronMan();
        ironman.realName = "Tony Stark";
        // or
        ironman.setAge(30);
    }

}

This is how we use the instance variables. Shameless plug: This example was pulled from this free e-book here here.

Found this: https://coderwall.com/p/ngisma where Nathan Walker (near bottom of page) suggests a decorator in $rootScope to create func 'safeApply', code:

yourAwesomeModule.config([
  '$provide', function($provide) {
    return $provide.decorator('$rootScope', [
      '$delegate', function($delegate) {
        $delegate.safeApply = function(fn) {
          var phase = $delegate.$$phase;
          if (phase === "$apply" || phase === "$digest") {
            if (fn && typeof fn === 'function') {
              fn();
            }
          } else {
            $delegate.$apply(fn);
          }
        };
        return $delegate;
      }
    ]);
  }
]);

Hmmm $array = json_decode($json, true); will make your string an array which is easy to print nicely with print_r($array, true);

But if you really want to prettify your json... Check this out

You probably haven't installed GLUT:

1. Install GLUT If you do not have GLUT installed on your machine you can download it from: http://www.xmission.com/~nate/glut/glut-3.7.6-bin.zip (or whatever version) GLUT Libraries and header files are • glut32.lib • glut.h

Source: http://cacs.usc.edu/education/cs596/OGL_Setup.pdf

EDIT:

The quickest way is to download the latest header, and compiled DLLs for it, place it in your system32 folder or reference it in your project. Version 3.7 (latest as of this post) is here: http://www.opengl.org/resources/libraries/glut/glutdlls37beta.zip

Folder references:

glut.h: 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\GL\'
glut32.lib: 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib\'
glut32.dll: 'C:\Windows\System32\'

For 64-bit machines, you will want to do this.
glut32.dll: 'C:\Windows\SysWOW64\'

Same pattern applies to freeglut and GLEW files with the header files in the GL folder, lib in the lib folder, and dll in the System32 (and SysWOW64) folder.
1. Under Visual C++, select Empty Project.
2. Go to Project -> Properties. Select Linker -> Input then add the following to the Additional Dependencies field:
opengl32.lib
glu32.lib
glut32.lib

I have successfully used the java.net.URI class like so:

public static String uriEncode(String string) {
    String result = string;
    if (null != string) {
        try {
            String scheme = null;
            String ssp = string;
            int es = string.indexOf(':');
            if (es > 0) {
                scheme = string.substring(0, es);
                ssp = string.substring(es + 1);
            }
            result = (new URI(scheme, ssp, null)).toString();
        } catch (URISyntaxException usex) {
            // ignore and use string that has syntax error
        }
    }
    return result;
}

By default, gcc selects the language based on the file extension, but you can force gcc to select a different language backend with the -x option thus:

gcc -x c++

More options are detailed in the gcc man page under "Options controlling the kind of output". See e.g. http://linux.die.net/man/1/gcc (search on the page for the text -x language).

This facility is very useful in cases where gcc can't guess the language using a file extension, for example if you're generating code and feeding it to gcc via stdin.

You can define a method in spec_helper.rb that sends a message both to Rails.logger.info and to puts and use that for debugging:

def log_test(message)
    Rails.logger.info(message)
    puts message
end

Please use the attributes from the System.Web.Http namespace on your WebAPI actions:

    [System.Web.Http.AcceptVerbs("GET", "POST")]
    [System.Web.Http.HttpGet]
    public string Auth(string username, string password)
    {...}

The reason why it doesn't work is because you were using the attributes that are from the MVC namespace System.Web.Mvc. The classes in the System.Web.Http namespace are for WebAPI.

I had met this problem too.And I found that happend beacuse I forgot to add the user-name before the host name: like this:

ssh -i test.pem ec2-32-122-42-91.us-west-2.compute.amazonaws.com

and I add the user name:

ssh -i test.pem [email protected]

it works!

if your int variable is declared as a class level variable (instance variable) it would be defaulted to 0. But that does not indicate if the value sent from the client was 0 or a null. may be you could have a setter method which could be called to initialize/set the value sent by the client. then you can define your indicator value , may be a some negative value to indicate the null..

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

expression is your friend:

plot(1,1, main=expression('title'^2))  #superscript
plot(1,1, main=expression('title'[2])) #subscript

I have a similar table styled like so:

<table style="width:100%; table-layout:fixed">
    <tr>
        <td style="width: 150px">Hello, World!</td>
        <td>
            <div>
                <pre style="margin:0; overflow:scroll">My preformatted content</pre>
            </div>
        </td>
    </tr>
</table>

try this for comparision

if "%INPUT%"=="y"...

Instead of declaring array which hold all the month name and then pointing with an index, we can also write it in a shorter version as below:

var objDate = new Date().toLocaleString("en-us", { month: "long" }); // result: August
var objDate = new Date().toLocaleString("en-us", { month: "short" }); // result: Aug

If you're using scss for your styles you can use a mixin to help generate the code. Your styles will quickly get out of hand if you put all the properties every time.

This is a very simple example - really nothing more than a proof of concept, you can extend this with multiple properties and rules as needed.

@mixin mat-table-columns($columns)
{
    .mat-column-
    {
        @each $colName, $props in $columns {

            $width: map-get($props, 'width');

            &#{$colName} 
            {
                flex: $width;
                min-width: $width;

                @if map-has-key($props, 'color') 
                {
                    color: map-get($props, 'color');
                }
            }  
        }
    }
}

Then in your component where your table is defined you just do this:

@include mat-table-columns((

    orderid: (width: 6rem, color: gray),
    date: (width: 9rem),
    items: (width: 20rem)

));

This generates something like this:

.mat-column-orderid[_ngcontent-c15] {
  flex: 6rem;
  min-width: 6rem;
  color: gray; }

.mat-column-date[_ngcontent-c15] {
  flex: 9rem;
  min-width: 9rem; }

In this version width becomes flex: value; min-width: value.

For your specific example you could add wrap: true or something like that as a new parameter.

Below is how I got this working.

The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.

[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]

[HttpPost]  
  public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)  
  {            
     var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
     return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
  }

The JQuery script used to call this action method:

var requestData = {
         InvoiceNumber: $.trim(this.value),
         SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
      };


      $.ajax({
         url: '/en/myController/GetDataForInvoiceNumber',
         type: 'POST',
         data: JSON.stringify(requestData),
         dataType: 'json',
         contentType: 'application/json; charset=utf-8',
         error: function (xhr) {
            alert('Error: ' + xhr.statusText);
         },
         success: function (result) {
            CheckIfInvoiceFound(result);
         },
         async: true,
         processData: false
      });

Although it's a long time after this question is being asked since I was searching so much for the same problem and couldn't find the extant solutions helpful, I write what fixed my trouble for anyone with the same issue: The point is, Jupyter should be installed in your virtual environment, meaning, after activating the tensorflow environment, run the following in the command prompt (in tensorflow virtual environment):

conda install jupyter
jupyter notebook

and then the jupyter will pop up.

You have to load the db library first. In autoload.php add :

$autoload['libraries'] = array('database');

Also, try renaming User model class for "User_model".

const int* ptr; 

declares ptr a pointer to const int type. You can modify ptr itself but the object pointed to by ptr shall not be modified.

const int a = 10;
const int* ptr = &a;  
*ptr = 5; // wrong
ptr++;    // right  

While

int * const ptr;  

declares ptr a const pointer to int type. You are not allowed to modify ptr but the object pointed to by ptr can be modified.

int a = 10;
int *const ptr = &a;  
*ptr = 5; // right
ptr++;    // wrong

Generally I would prefer the declaration like this which make it easy to read and understand (read from right to left):

int const  *ptr; // ptr is a pointer to constant int 
int *const ptr;  // ptr is a constant pointer to int

I just want to edit this for posterity that the tags for oracle weren't added when I answered this question. My response was more applicable to MS SQL.

Merge join is the best possible as it exploits the ordering, resulting in a single pass down the tables to do the join. IF you have two tables (or covering indexes) that have their ordering the same such as a primary key and an index of a table on that key then a merge join would result if you performed that action.

Hash join is the next best, as it's usually done when one table has a small number (relatively) of items, its effectively creating a temp table with hashes for each row which is then searched continuously to create the join.

Worst case is nested loop which is order (n * m) which means there is no ordering or size to exploit and the join is simply, for each row in table x, search table y for joins to do.

If you can, I strongly suggest you tar and bzip (or gzip, whatever floats your boat) the directory on the remote machine—for a directory of any significant size, the bandwidth savings will probably be worth the time to zip/unzip.
