Any chance that you changed the name of your table view from "tableView" to "myTableView" at some point?

TL;DR: Scan down to image, and then check out working project here.

Updating my answer for a simpler solution that I found..

In my case, I wanted to fix the width, and have variable height cells. I wanted a drop in, reusable solution that handled rotation and didn't require a lot of intervention.

What I arrived at, was override (just) systemLayoutFitting(...) in the collection cell (in this case a base class for me), and first defeat UICollectionView's effort to set the wrong dimension on contentView by adding a constraint for the known dimension, in this case, the width.

class EstimatedWidthCell: UICollectionViewCell {
    override init(frame: CGRect) {
        super.init(frame: frame)
        contentView.translatesAutoresizingMaskIntoConstraints = false
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        contentView.translatesAutoresizingMaskIntoConstraints = false
    }

    override func systemLayoutSizeFitting(
        _ targetSize: CGSize, withHorizontalFittingPriority
        horizontalFittingPriority: UILayoutPriority,
        verticalFittingPriority: UILayoutPriority) -> CGSize {

        width.constant = targetSize.width

and then return the final size for the cell - used for (and this feels like a bug) the dimension of the cell itself, but not contentView - which is otherwise constrained to a conflicting size (hence the constraint above). To calculate the correct cell size, I use a lower priority for the dimension that I wanted to float, and I get back the height required to fit the content within the width to which I want to fix:

        let size = contentView.systemLayoutSizeFitting(
            CGSize(width: targetSize.width, height: 1),
            withHorizontalFittingPriority: .required,
            verticalFittingPriority: verticalFittingPriority)

        print("\(#function) \(#line) \(targetSize) -> \(size)")
        return size
    }

    lazy var width: NSLayoutConstraint = {
        return contentView.widthAnchor
            .constraint(equalToConstant: bounds.size.width)
            .isActive(true)
    }()
}

But where does this width come from? It is configured via the estimatedItemSize on the collection view's flow layout:

lazy var collectionView: UICollectionView = {
    let view = UICollectionView(frame: CGRect(), collectionViewLayout: layout)
    view.backgroundColor = .cyan
    view.translatesAutoresizingMaskIntoConstraints = false
    return view
}()

lazy var layout: UICollectionViewFlowLayout = {
    let layout = UICollectionViewFlowLayout()
    let width = view.bounds.size.width // should adjust for inset
    layout.estimatedItemSize = CGSize(width: width, height: 10)
    layout.scrollDirection = .vertical
    return layout
}()

Finally, to handle rotation, I implement trailCollectionDidChange to invalidate the layout:

override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
    layout.estimatedItemSize = CGSize(width: view.bounds.size.width, height: 10)
    layout.invalidateLayout()
    super.traitCollectionDidChange(previousTraitCollection)
}

The final result looks like this:

And I have published a working sample here.

This started to happen for me on Xcode 7, and I had no outlets with yellow flags that I could delete.

The only thing that worked for me was replacing this line in the AppDelegate:

[window addSubview:viewController.view];

to:

[window setRootViewController:viewController];

This happened to me while trying to copy over the PSPDFKIT demo library into my project. I followed all the instructions in the site + all the suggestions on this page.. for some reason it kept on giving the above error, the problem was that if i grepped the message in the error method.. it only appeared in the binary (obviously I have no access to the source code b/c I have to pay for it).

I noticed this in the instruction page though:

So I went to the guts of that config file and found this:

OTHER_LDFLAGS=$(inherited) -ObjC -fobjc-arc -lz -framework CoreText -framework CoreMedia -framework MediaPlayer -framework AVFoundation -framework ImageIO -framework MediaPlayer -framework MessageUI -framework CoreGraphics -framework Foundation -framework QuartzCore -framework AVFoundation -framework CFNetwork -framework MobileCoreServices -framework SystemConfiguration -weak_framework UIKit

Then I went to the sample project provided by the author of the said library.. and noticed that the previous flags where copied verbatim to the other linker flags in my build settings.. however in my project.. they were not!.. So i simply copied and pasted them into my project's build settings other linker flags and everything worked!

take away point: if you are relying on some .xcconfig file on your setup, double check with a sample code source or something and make sure that it has actually been applied.. it wasn't applied properly in my case

If you are using docker to deploy the spring boot app, you can set the profile using the flag e:

docker run -e "SPRING_PROFILES_ACTIVE=prod" -p 8080:8080 -t r.test.co/myapp:latest

You can also get them with pure javascript.

For example:

new URL(location.href).searchParams.get('page')

For this url: websitename.com/user/?page=1, it would return a value of 1

header("HTTP/1.1 200 OK");
http_response_code(201);
header("Status: 200 All rosy");

http_response_code(200); not work because test alert 404 https://developers.google.com/speed/pagespeed/insights/

Two nitpicks. (1) Best not to use string literals for column alias - that is deprecated. (2) Just use style 120 to get the same value.

    CASE 
      WHEN CreatedDate = '19000101' THEN '' 
      WHEN CreatedDate = '18000101' THEN '' 
      ELSE Convert(varchar(19), CreatedDate, 120)
    END AS [Created Date]

Generic way to update the any JSONObjet with new values.

private static void updateJsonValues(JsonObject jsonObj) {
    for (Map.Entry<String, JsonElement> entry : jsonObj.entrySet()) {
        JsonElement element = entry.getValue();
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        } else if (element.isJsonPrimitive()) {
            jsonObj.addProperty(entry.getKey(), "<provide new value>");
        }

    }
}

private static void parseJsonArray(JsonArray asJsonArray) {
    for (int index = 0; index < asJsonArray.size(); index++) {
        JsonElement element = asJsonArray.get(index);
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        }

    }
}

nvm does its job by changing the PATH variable, so you need to make sure you aren't somehow changing your PATH to something else after sourcing the nvm.sh script.

In my case, nvm.sh was being called in .bashrc but then the PATH variable was getting updated in .bash_profile which caused my session to find the system node before the nvm node.

No, you cannot put an assignment inside a lambda because of its own definition. If you work using functional programming, then you must assume that your values are not mutable.

One solution would be the following code:

output = lambda l, name: [] if l==[] \
             else [ l[ 0 ] ] + output( l[1:], name ) if l[ 0 ].name == name \
             else output( l[1:], name ) if l[ 0 ].name == "" \
             else [ l[ 0 ] ] + output( l[1:], name )

As in the opencv-doc you can get video feed from a camera which is connected to your computer by following code.

import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
    # Capture frame-by-frame
    ret, frame = cap.read()
    # Our operations on the frame come here
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
    # Display the resulting frame
    cv2.imshow('frame',gray)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()

You can change cap = cv2.VideoCapture(0) index from 0 to 1 to access the 2nd camera.
Tested in opencv-3.2.0

the string in your question is not a valid json string. From json.org website:

JSON is built on two structures:

* A collection of name/value pairs. In various languages, this is 
  realized as an object, record, struct, dictionary, hash table, keyed list, or
  associative array.
* An ordered list of values. In most languages, this is realized as an
  array, vector, list, or sequence.

Basically a json string will always start with either { or [.

Then as @Andy E and @Cryo said you can parse the string with json2.js or some other libraries.

IMHO you should avoid eval because it will any javascript program, so you might incur in security issues.

I had, pretty much, the same problem. I was able to see that PDO was enabled but I had no available drivers (using PHP 7-RC4). I managed to resolve the issue by adding the php_pdo_mysql extension to those which were enabled.

Hope this helps!

Unfortunately, there is no :click pseudo selector. If you want to change styling on click, you should use Jquery/Javascript. It certainly is better than the "hack" for pure HTML / CSS. But if you insist...

input {_x000D_
display: none;_x000D_
}_x000D_
span {_x000D_
padding: 20px;_x000D_
font-family: sans-serif;_x000D_
}_x000D_
input:checked + span {_x000D_
  background: #444;_x000D_
  color: #fff;_x000D_
}

  <label for="input">_x000D_
  <input id="input" type="radio" />_x000D_
  <span>NO JS styling</span>_x000D_
  </label>

Or, if you prefer, you can toggle the styling:

input {_x000D_
display: none;_x000D_
}_x000D_
span {_x000D_
padding: 20px;_x000D_
font-family: sans-serif;_x000D_
}_x000D_
input:checked + span {_x000D_
  background: #444;_x000D_
  color: #fff;_x000D_
}

  <label for="input">_x000D_
  <input id="input" type="checkbox" />_x000D_
  <span>NO JS styling</span>_x000D_
  </label>

I think this works, too:

int power = 1;
while(power < x)
    power*=2;

And the answer is power.

Perhaps you just want to stop executing a long script at some point. ie. like you want to hard code an exit() in C or Python.

print("this is the last message")
stop()
print("you should not see this")

try this

    public Item anyItem()
    {
        int index = randomGenerator.nextInt(catalogue.size());
        System.out.println("Managers choice this week" + catalogue.get(index) + "our recommendation to you");
        return catalogue.get(index);
    }

And I strongly suggest you to get a book, such as Ivor Horton's Beginning Java 2

The solution with the /etc/docker/daemon.json file didn't work for me on Ubuntu.

I was able to configure Docker insecure registries on Ubuntu by providing command line options to the Docker daemon in /etc/default/docker file, e.g.:

# /etc/default/docker    
DOCKER_OPTS="--insecure-registry=a.example.com --insecure-registry=b.example.com"

The same way can be used to configure custom directory for docker images and volumes storage, default DNS servers, etc..

Now, after the Docker daemon has restarted (after executing sudo service docker restart), running docker info will show:

Insecure Registries:
  a.example.com
  b.example.com
  127.0.0.0/8

Distances to the source of iBeacon-formatted advertisement packets are estimated from the signal path attenuation calculated by comparing the measured received signal strength to the claimed transmit power which the transmitter is supposed to encode in the advertising data.

A path loss based scheme like this is only approximate and is subject to variation with things like antenna angles, intervening objects, and presumably a noisy RF environment. In comparison, systems really designed for distance measurement (GPS, Radar, etc) rely on precise measurements of propagation time, in same cases even examining the phase of the signal.

As Jiaru points out, 160 ft is probably beyond the intended range, but that doesn't necessarily mean that a packet will never get through, only that one shouldn't expect it to work at that distance.

The CGI is specified in RFC 3875, though that is a later "official" codification of the original NCSA document. Basically, CGI defines a protocol to pass data about a HTTP request from a webserver to a program to process - any program, in any language. At the time the spec was written (1993), most web servers contained only static pages, "web apps" were a rare and new thing, so it seemed natural to keep them apart from the "normal" static content, such as in a cgi-bin directory apart from the static content, and having them end in .cgi.

At this time, here also were no dedicated "web programming languages" like PHP, and C was the dominating portable programming language - so many people wrote their CGI scripts in C. But Perl quickly turned out to be a better fit for this kind of thing, and CGI became almost synonymous with Perl for a while. Then there came Java Servlets, PHP and a bunch of others and took over large parts of Perl's market share.

int x = thisObject.compareTo(anotherObject);

The compareTo() method returns an int with the following characteristics:

• negative If thisObject < anotherObject
• zero If thisObject == anotherObject
• positive If thisObject > anotherObject

Differentiating between the possible origins of exceptions raised from a compound with statement

Differentiating between exceptions that occur in a with statement is tricky because they can originate in different places. Exceptions can be raised from either of the following places (or functions called therein):

• ContextManager.__init__
• ContextManager.__enter__
• the body of the with
• ContextManager.__exit__

For more details see the documentation about Context Manager Types.

If we want to distinguish between these different cases, just wrapping the with into a try .. except is not sufficient. Consider the following example (using ValueError as an example but of course it could be substituted with any other exception type):

try:
    with ContextManager():
        BLOCK
except ValueError as err:
    print(err)

Here the except will catch exceptions originating in all of the four different places and thus does not allow to distinguish between them. If we move the instantiation of the context manager object outside the with, we can distinguish between __init__ and BLOCK / __enter__ / __exit__:

try:
    mgr = ContextManager()
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        with mgr:
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
    except ValueError as err:
        # At this point we still cannot distinguish between exceptions raised from
        # __enter__, BLOCK, __exit__ (also BLOCK since we didn't catch ValueError in the body)
        pass

Effectively this just helped with the __init__ part but we can add an extra sentinel variable to check whether the body of the with started to execute (i.e. differentiating between __enter__ and the others):

try:
    mgr = ContextManager()  # __init__ could raise
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        entered_body = False
        with mgr:
            entered_body = True  # __enter__ did not raise at this point
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
    except ValueError as err:
        if not entered_body:
            print('__enter__ raised:', err)
        else:
            # At this point we know the exception came either from BLOCK or from __exit__
            pass

The tricky part is to differentiate between exceptions originating from BLOCK and __exit__ because an exception that escapes the body of the with will be passed to __exit__ which can decide how to handle it (see the docs). If however __exit__ raises itself, the original exception will be replaced by the new one. To deal with these cases we can add a general except clause in the body of the with to store any potential exception that would have otherwise escaped unnoticed and compare it with the one caught in the outermost except later on - if they are the same this means the origin was BLOCK or otherwise it was __exit__ (in case __exit__ suppresses the exception by returning a true value the outermost except will simply not be executed).

try:
    mgr = ContextManager()  # __init__ could raise
except ValueError as err:
    print('__init__ raised:', err)
else:
    entered_body = exc_escaped_from_body = False
    try:
        with mgr:
            entered_body = True  # __enter__ did not raise at this point
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
            except Exception as err:  # this exception would normally escape without notice
                # we store this exception to check in the outer `except` clause
                # whether it is the same (otherwise it comes from __exit__)
                exc_escaped_from_body = err
                raise  # re-raise since we didn't intend to handle it, just needed to store it
    except ValueError as err:
        if not entered_body:
            print('__enter__ raised:', err)
        elif err is exc_escaped_from_body:
            print('BLOCK raised:', err)
        else:
            print('__exit__ raised:', err)

Alternative approach using the equivalent form mentioned in PEP 343

PEP 343 -- The "with" Statement specifies an equivalent "non-with" version of the with statement. Here we can readily wrap the various parts with try ... except and thus differentiate between the different potential error sources:

import sys

try:
    mgr = ContextManager()
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        value = type(mgr).__enter__(mgr)
    except ValueError as err:
        print('__enter__ raised:', err)
    else:
        exit = type(mgr).__exit__
        exc = True
        try:
            try:
                BLOCK
            except TypeError:
                pass
            except:
                exc = False
                try:
                    exit_val = exit(mgr, *sys.exc_info())
                except ValueError as err:
                    print('__exit__ raised:', err)
                else:
                    if not exit_val:
                        raise
        except ValueError as err:
            print('BLOCK raised:', err)
        finally:
            if exc:
                try:
                    exit(mgr, None, None, None)
                except ValueError as err:
                    print('__exit__ raised:', err)

Usually a simpler approach will do just fine

The need for such special exception handling should be quite rare and normally wrapping the whole with in a try ... except block will be sufficient. Especially if the various error sources are indicated by different (custom) exception types (the context managers need to be designed accordingly) we can readily distinguish between them. For example:

try:
    with ContextManager():
        BLOCK
except InitError:  # raised from __init__
    ...
except AcquireResourceError:  # raised from __enter__
    ...
except ValueError:  # raised from BLOCK
    ...
except ReleaseResourceError:  # raised from __exit__
    ...

If you used read.table() (or one of it's ilk, e.g. read.csv()) then the easy fix is to change the call to:

read.table(file = "foo.txt", row.names = 1, ....)

where .... are the other arguments you needed/used. The row.names argument takes the column number of the data file from which to take the row names. It need not be the first column. See ?read.table for details/info.

If you already have the data in R and can't be bothered to re-read it, or it came from another route, just set the rownames attribute and remove the first variable from the object (assuming obj is your object)

rownames(obj) <- obj[, 1]  ## set rownames
obj <- obj[, -1]           ## remove the first variable

Because break can only be used inside a loop. It is used to break out of a loop (stop the loop).

This should work :

MyInstace.GetType().GetInterfaces();

But nice too :

if (obj is IMyInterface)

Or even (not very elegant) :

if (obj.GetType() == typeof(IMyInterface))

Python prefers English keywords to punctuation. Use not x, i.e. not os.path.exists(...). The same thing goes for && and || which are and and or in Python.

If you are using Float or Integer then you can assign default value like this ...

Integer[] data = new Integer[20];
Arrays.fill(data,new Integer(0));

The h1 tags unfortunately do not receive the onmouseout events.

The simple Javascript snippet below will work for all elements and uses only 1 mouse event.

Note: "The borders in the snippet are applied to provide a visual demarcation of the elements."

document.body.onmousemove = function(){ move("The dog is in its shed"); };_x000D_
_x000D_
document.body.style.border = "2px solid red";_x000D_
document.getElementById("h1Tag").style.border = "2px solid blue";_x000D_
_x000D_
function move(what) {_x000D_
    if(event.target.id == "h1Tag"){ document.getElementById("goy").innerHTML = "what"; } else { document.getElementById("goy").innerHTML = ""; }_x000D_
}

<h1 id="h1Tag">lalala</h1>_x000D_
<div id="goy"></div>

This can also be done in pure CSS by adding the hover selector css property to the h1 tag.

I increased build number but the problem remained.

Then,

1. I approved renewed licence agreement at itunesconnect.
2. I opened App Store application on my MAC, and clicked update button for "Command Line Tools (OS X 10.11) for XCode, Version 7.3"
3. I opened XCode. Clicked "Product" button on top bar. While tab content is open, I clicked "alt" key of keyboard to make "Clean Build Folder" option visible. I clicked this option.
4. I rebuild my application for the same version that I received below error;

This action could not be completed. Try Again (-22421)

5. This time I received below error when I want to upload new version;

This action could not be completed. Try again.

6. I clicked Done and clicked blue "Upload to App Store" button again, and upload completed successfully.

I hope this helps.

Check you have the line:

 import org.json.JSONArray;

at the top of your source code

If you are using OkHttp for Java/Android you can use the following constant:

import com.squareup.okhttp.internal.Util;

Util.UTF_8; // Charset
Util.UTF_8.name(); // String

I think what might help you is the MULTI/EXEC/DISCARD. While not 100% equivalent of transactions, you should be able to isolate the deletes from other updates.

You usually don't want to do this. With Docker Compose you define services that compose your app. npm and manage.py are just management commands. You don't need a container for them. If you need to, say create your database tables with manage.py, all you have to do is:

docker-compose run client python manage.py create_db

Think of it as the one-off dynos Heroku uses.

If you really need to treat these management commands as separate containers (and also use Docker Compose for these), you could create a separate .yml file and start Docker Compose with the following command:

docker-compose up -f my_custom_docker_compose.yml

You could use toArray() to convert into an array of Objects followed by this method to convert the array of Objects into an array of Strings:

Object[] objectArray = lst.toArray();
String[] stringArray = Arrays.copyOf(objectArray, objectArray.length, String[].class);

<?php
// Example API call
$data = array(array (
    "REGION" => "MUMBAI",
    "LOCATION" => "NA",
    "STORE" => "AMAZON"));
// json encode data
$authToken = "xxxxxxxxxx";
$data_string = json_encode($data); 
// set up the curl resource
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://domainyouhaveapi.com");   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type:application/json',       
    'Content-Length: ' . strlen($data_string) ,
    'API-TOKEN-KEY:'.$authToken ));   // API-TOKEN-KEY is keyword so change according to ur key word. like authorization 
// execute the request
$output = curl_exec($ch);
//echo $output;
// Check for errors
if($output === FALSE){
    die(curl_error($ch));
}
echo($output) . PHP_EOL;
// close curl resource to free up system resources
curl_close($ch);

Use the (ngModelChange) event to detect changes on the model

Replace the whitespace characters, and then convert it(using the intval function or by regular typecasting)

intval(str_replace(" ", "", $b))

Use nohup if your background job takes a long time to finish or you just use SecureCRT or something like it login the server.

Redirect the stdout and stderr to /dev/null to ignore the output.

nohup /path/to/your/script.sh > /dev/null 2>&1 &

According to the json.org specification, your return is invalid. The names are always quoted, so you should be returning

{ "title": "One", "key": "1" }

and

[ { "title": "One", "key": "1" }, { "title": "Two", "key": "2" } ]

This may not be the problem with your setup, since you say one of them works now, but it should be fixed for correctness in case you need to switch to another JSON parser in the future.

You can change style directly for scene using .root class:

.root {
    -fx-background-image: url("https://www.google.com/images/srpr/logo3w.png");
}

Add this to CSS and load it as "Uluk Biy" described in his answer.

You specifically asked for "extension or functionality in Chrome and/or Firefox", which the answers you have already received provide, but I do like the simplicity of oezi's answer to the closed question "how to send a post request with a web browser" for simple parameters. oezi says:

with a form, just set method to "post"

<form action="blah.php" method="post">
  <input type="text" name="data" value="mydata" />
  <input type="submit" />
</form>

I.e. build yourself a very simple page to test the post actions.

It help me to clean a system, with MVC in CakePhp, as i work in Linux, Windows, with different tools.. in some files my design was break.. so after checkin in Chrome with debug tool find the &#65279 error

Use read.table with colClasses instances of "NULL" to avoid creating them in the first place:

## example data and temp file
x <- data.frame(x = 1:10, y = rnorm(10), z = runif(10), a = letters[1:10], stringsAsFactors = FALSE)
tmp <- tempfile()
write.table(x, tmp, row.names = FALSE)


(y <- read.table(tmp, colClasses = c("numeric", rep("NULL", 2), "character"), header = TRUE))

x a
1   1 a
2   2 b
3   3 c
4   4 d

6   6 f

8   8 h

$sidemenu is not an object, so you can't call methods on it. It is probably not being sent to your view, or $sidemenus is empty.

You can pass values by using the below .

@Html.ActionLink("About", "About", "Home",new { name = ViewBag.Name }, htmlAttributes:null )

Controller:

public ActionResult About(string name)
        {
            ViewBag.Message = "Your application description page.";
            ViewBag.NameTransfer = name;
            return View();
        }

And the URL looks like

http://localhost:50297/Home/About?name=My%20Name%20is%20Vijay

It seems that if

• Content-Type: application/json and
• if POST body isn't tightly bound to controller's input object class

Then MVC doesn't really bind the POST body to any particular class. Nor can you just fetch the POST body as a param of the ActionResult (suggested in another answer). Fair enough. You need to fetch it from the request stream yourself and process it.

[HttpPost]
public ActionResult Index(int? id)
{
    Stream req = Request.InputStream;
    req.Seek(0, System.IO.SeekOrigin.Begin);
    string json = new StreamReader(req).ReadToEnd();

    InputClass input = null;
    try
    {
        // assuming JSON.net/Newtonsoft library from http://json.codeplex.com/
        input = JsonConvert.DeserializeObject<InputClass>(json)
    }

    catch (Exception ex)
    {
        // Try and handle malformed POST body
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }

    //do stuff

}

Update:

for Asp.Net Core, you have to add [FromBody] attrib beside your param name in your controller action for complex JSON data types:

[HttpPost]
public ActionResult JsonAction([FromBody]Customer c)

Also, if you want to access the request body as string to parse it yourself, you shall use Request.Body instead of Request.InputStream:

Stream req = Request.Body;
req.Seek(0, System.IO.SeekOrigin.Begin);
string json = new StreamReader(req).ReadToEnd();

Header files needed:

#include <iostream>
#include <fstream>

declare input file stream:

ifstream in("in.txt");

declare output file stream:

ofstream out("out.txt");

if you want to use variable for a file name, instead of hardcoding it, use this:

string file_name = "my_file.txt";
ifstream in2(file_name.c_str());

reading from file into variables (assume file has 2 int variables in):

int num1,num2;
in >> num1 >> num2;

or, reading a line a time from file:

string line;
while(getline(in,line)){
//do something with the line
}

write variables back to the file:

out << num1 << num2;

close the files:

in.close();
out.close();

You can try:

colour = ["red", "red", "green", "yellow"]

with open('mypage.html', 'w') as myFile:
    myFile.write('<html>')
    myFile.write('<body>')
    myFile.write('<table>')

    s = '1234567890'
    for i in range(0, len(s), 60):
        myFile.write('<tr><td>%04d</td>' % (i+1));
    for j, k in enumerate(s[i:i+60]):
        myFile.write('<td><font style="background-color:%s;">%s<font></td>' % (colour[j %len(colour)], k));


    myFile.write('</tr>')
    myFile.write('</table>')
    myFile.write('</body>')
    myFile.write('</html>')

/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/jsp-api-6.0.16.jar
/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/servlet-api-6.0.16.jar

You should not have any server-specific libraries in the /WEB-INF/lib. Leave them in the appserver's own library. It would only lead to collisions in the classpath. Get rid of all appserver-specific libraries in /WEB-INF/lib (and also in JRE/lib and JRE/lib/ext if you have placed any of them there).

A common cause that the appserver-specific libraries are included in the webapp's library is that starters think that it is the right way to fix compilation errors of among others the javax.servlet classes not being resolveable. Putting them in webapp's library is the wrong solution. You should reference them in the classpath during compilation, i.e. javac -cp /path/to/server/lib/servlet.jar and so on, or if you're using an IDE, you should integrate the server in the IDE and associate the web project with the server. The IDE will then automatically take server-specific libraries in the classpath (buildpath) of the webapp project.

In certain situations you must have a named parameter but you don't use it directly.
For example, I ran into it on VS2010, when 'e' is used only inside a decltype statement, the compiler complains but you must have the named varible e.

All the above non-#pragma suggestions all boil down to just adding a single statement:

bool f(int e)
{ 
   // code not using e
   return true;
   e; // use without doing anything
}

One considerable difference is about porting Python2 to Python3. urllib2 does not exist for python3 and its methods ported to urllib. So you are using that heavily and want to migrate to Python3 in future, consider using urllib. However 2to3 tool will automatically do most of the work for you.

As far as I can remember, the first versions of C only allowed to return a value that could fit into a processor register, which means that you could only return a pointer to a struct. The same restriction applied to function arguments.

More recent versions allow to pass around larger data objects like structs. I think this feature was already common during the eighties or early nineties.

Arrays, however, can still be passed and returned only as pointers.

I used to always get confused whether I should use break, or continue. This is what helps me remember:

When to use break vs continue?

1. Break - it's like breaking up. It's sad, you guys are parting. The loop is exited.

2. Continue - means that you're gonna give today a rest and sort it all out tomorrow (i.e. skip the current iteration)!

Old one but I would add my answer as per my findings:

var ancestralState = context.findAncestorStateOfType<ParentState>();
      ancestralState.setState(() {
        // here you can access public vars and update state.
        ...
      });

The binary representation is the key. An Example: Unsigned int in HEX

 0XFFFFFFF = translates to = 1111 1111 1111 1111 1111 1111 1111 1111 

Which represents 4,294,967,295 in a base-ten positive number. But we also need a way to represent negative numbers. So the brains decided on twos complement. In short, they took the leftmost bit and decided that when it is a 1 (followed by at least one other bit set to one) the number will be negative. And the leftmost bit is set to 0 the number is positive. Now let's look at what happens

0000 0000 0000 0000 0000 0000 0000 0011 = 3

Adding to the number we finally reach.

0111 1111 1111 1111 1111 1111 1111 1111 = 2,147,483,645

the highest positive number with a signed integer. Let's add 1 more bit (binary addition carries the overflow to the left, in this case, all bits are set to one, so we land on the leftmost bit)

1111 1111 1111 1111 1111 1111 1111 1111 = -1

So I guess in short we could say the difference is the one allows for negative numbers the other does not. Because of the sign bit or leftmost bit or most significant bit.

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

Here is an example using the DOM cookie API (https://developer.mozilla.org/en-US/docs/Web/API/Document/cookie), so we can see for ourselves the behavior.

If we execute the following JavaScript:

document.cookie = "key=value"

It appears to be the same as executing:

document.cookie = "key=value;domain=mydomain.com"

The cookie key becomes available (only) on the domain mydomain.com.

Now, if you execute the following JavaScript on mydomain.com:

document.cookie = "key=value;domain=.mydomain.com"

The cookie key becomes available to mydomain.com as well as subdomain.mydomain.com.

Finally, if you were to try and execute the following on subdomain.mydomain.com:

document.cookie = "key=value;domain=.mydomain.com"

Does the cookie key become available to subdomain.mydomain.com? I was a bit surprised that this is allowed; I had assumed it would be a security violation for a subdomain to be able to set a cookie on a parent domain.

Hi starbeamrainbowlabs ,

You can do this with the following:

var oldValue = "pic quality, hello" ;
var newValue =  "hello";
var oldValueLength = oldValue.length ;
var newValueLength = newValue.length ;
var from = oldValue.search(newValue) ;
var to = from + newValueLength ;
var nes = oldValue.substr(0,from) + oldValue.substr(to,oldValueLength);
console.log(nes);

I tested this in my javascript console so you can also check this out Thanks

There are 2 options to find matching text; string.match or string.find.

Both of these perform a regex search on the string to find matches.

string.find()

string.find(subject string, pattern string, optional start position, optional plain flag)

Returns the startIndex & endIndex of the substring found.

The plain flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger) being interpreted as a regex capture group matching for tiger, it instead looks for (tiger) within a string.

Going the other way, if you want to regex match but still want literal special characters (such as .()[]+- etc.), you can escape them with a percentage; %(tiger%).

You will likely use this in combination with string.sub

Example

str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

string.match()

string.match(s, pattern, optional index)

Returns the capture groups found.

Example

str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

You may get more success if you do a "search" for the runtime env from the preferences screen instead of hitting "add" - see this demo on youtube. http://www.youtube.com/watch?v=EOkN5IPoJVs&playnext_from=TL&videos=rVnITzSU2Z8 - When you hit search, you are prompted to point to the tomcat directory and then it SHOULD add it as a server runtime environment. Unfortunately for me, that is not the case (I get "no new server runtime environments were found") But you might have more success.

Use this code to pass arraylist<customobj> to anthother Activity

firstly serialize our contact bean

public class ContactBean implements Serializable {
      //do intialization here
}

Now pass your arraylist

 Intent intent = new Intent(this,name of activity.class);
 contactBean=(ConactBean)_arraylist.get(position);
 intent.putExtra("contactBeanObj",conactBean);
 _activity.startActivity(intent);

If you're using C# 6 or later, you can use expression-bodied syntax for get-only indexer:

public object this[int i] => this.InnerList[i];

force it with -l

    sudo umount -l ${HOME}/mount_dir

An example of how to do this using a lambda expression would be:

issublist = lambda x, y: 0 in [_ in x for _ in y]

Pro Git 8.2 explains it: http://git-scm.com/book/en/Git-and-Other-Systems-Migrating-to-Git

The accepted answer is correct. However, I needed a little bit more clarity, so in case someone else does too:

Leaflet allows events to fire on virtually anything you do on its map, in this case a marker.

So you could create a marker as suggested by the question above:

L.marker([10.496093,-66.881935]).addTo(map).on('mouseover', onClick);

Then create the onClick function:

function onClick(e) {
    alert(this.getLatLng());
}

Now anytime you mouseover that marker it will fire an alert of the current lat/long.

However, you could use 'click', 'dblclick', etc. instead of 'mouseover' and instead of alerting lat/long you can use the body of onClick to do anything else you want:

L.marker([10.496093,-66.881935]).addTo(map).on('click', function(e) {
    console.log(e.latlng);
});

Here is the documentation: http://leafletjs.com/reference.html#events

I would use:

CAST
(
CAST(YEAR(DATEFIELD) as varchar(4)) + '/' CAST(MM(DATEFIELD) as varchar(2)) + '/' CAST(DD(DATEFIELD) as varchar(2)) as datetime
) 

Thus effectively creating a new field from the date field you already have.

 <TextView
        android:id="@+id/tvName"
        style="@style/textViewBoldLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:text="Welcome"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"/>

hash_map is a non-standard extension. unordered_map is part of std::tr1, and will be moved into the std namespace for C++0x. http://en.wikipedia.org/wiki/Unordered_map_%28C%2B%2B%29

try by Adding following onClientClick event.

OnClientClick="aspnetForm.target ='_blank';"

so on click it will call Javascript function an will open respective link in News tab.

<asp:LinkButton id="lbnkVidTtile1" OnClientClick="aspnetForm.target ='_blank';" runat="Server" CssClass="bodytext" Text='<%# Eval("newvideotitle") %>'  />

AngularJS pass string, numbers and booleans by value while it passes arrays and objects by reference. So you can create an empty object and make your date a property of that object. In that way angular will detect model changes.

In controller

app.module('yourModule').controller('yourController',function($scope){
$scope.vm={selectedDate:''}
});

In html

<div ng-controller="yourController">
<input id="selectedDueDate" type="text" ng-model="vm.selectedDate" />
</div>

Send the passwordbox control as a parameter to your login command.

<Button Command="{Binding LoginCommand}" CommandParameter="{Binding ElementName=PasswordBox}"...>

Then you can call CType(parameter, PasswordBox).Password in your viewmodel.

Other answers suggest how to get a floating-point value. While this wlil be close to what you want, it won't be exact:

>>> 0.4/100.
0.0040000000000000001

If you actually want a decimal value, do this:

>>> import decimal
>>> decimal.Decimal('4') / decimal.Decimal('100')
Decimal("0.04")

That will give you an object that properly knows that 4 / 100 in base 10 is "0.04". Floating-point numbers are actually in base 2, i.e. binary, not decimal.

Here's a performance comparison of the two. HTTP is more responsive for request-response of small files, but FTP may be better for large files if tuned properly. FTP used to be generally considered faster. FTP requires a control channel and state be maintained besides the TCP state but HTTP does not. There are 6 packet transfers before data starts transferring in FTP but only 4 in HTTP.

I think a properly tuned TCP layer would have more effect on speed than the difference between application layer protocols. The Sun Blueprint Understanding Tuning TCP has details.

Heres another good comparison of individual characteristics of each protocol.

I have used an emulator for API Level 23, which does not take keyboard input for installed apk. So I have created new emulator for API Level 29, and then it works. Following is the step to install new emulator.

1. Open "Android Virtual Device Manager"
2. Create new Virtual Device.
3. When you select a system image, please choose and download the last version(API Level29) on "Virtual Device Configuration" window

A property is in the DOM; an attribute is in the HTML that is parsed into the DOM.

Further detail

If you change an attribute, the change will be reflected in the DOM (sometimes with a different name).

Example: Changing the class attribute of a tag will change the className property of that tag in the DOM. If you have no attribute on a tag, you still have the corresponding DOM property with an empty or a default value.

Example: While your tag has no class attribute, the DOM property className does exist with a empty string value.

edit

If you change the one, the other will be changed by a controller, and vice versa. This controller is not in jQuery, but in the browser's native code.

The value of __FILE__ is a relative path that is created and stored (but never updated) when your file is loaded. This means that if you have any calls to Dir.chdir anywhere else in your application, this path will expand incorrectly.

puts __FILE__
Dir.chdir '../../'
puts __FILE__

One workaround to this problem is to store the expanded value of __FILE__ outside of any application code. As long as your require statements are at the top of your definitions (or at least before any calls to Dir.chdir), this value will continue to be useful after changing directories.

$MY_FILE_PATH = File.expand_path(File.dirname(__FILE__))

# open class and do some stuff that changes directory

puts $MY_FILE_PATH

Try doing this, there's no special character to concatenate in bash :

mystring="${arg1}12${arg2}endoffile"

explanations

If you don't put brackets, you will ask bash to concatenate $arg112 + $argendoffile (I guess that's not what you asked) like in the following example :

mystring="$arg112$arg2endoffile"

The brackets are delimiters for the variables when needed. When not needed, you can use it or not.

another solution

$ arg1=foo
$ arg2=bar
$ mystring="$arg1"
$ mystring+="12"
$ mystring+="$arg2"
$ mystring+="endoffile"
$ echo "$mystring"
foo12barendoffile

See http://mywiki.wooledge.org/BashFAQ/013

Best shown by example. String. 192.168.1.1 and a greedy regex \b.+\b You might think this would give you the 1st octet but is actually matches against the whole string. Why? Because the.+ is greedy and a greedy match matches every character in 192.168.1.1 until it reaches the end of the string. This is the important bit! Now it starts to backtrack one character at a time until it finds a match for the 3rd token (\b).

If the string a 4GB text file and 192.168.1.1 was at the start you could easily see how this backtracking would cause an issue.

To make a regex non greedy (lazy) put a question mark after your greedy search e.g

*?
??
+?

What happens now is token 2 (+?) finds a match, regex moves along a character and then tries the next token (\b) rather than token 2 (+?). So it creeps along gingerly.

IFS The Internal Field Separator that is used for word splitting after expansion and to split lines into words with the read builtin command. The default value is ``''.

IFS is a shell environment variable so it will remain unchanged within the context of your Shell script but not otherwise, unless you EXPORT it. ALSO BE AWARE, that IFS will not likely be inherited from your Environment at all: see this gnu post for the reasons and more info on IFS.

You're code written like this:

IFS=","
for word in $(cat tmptest | sed -n 1'p' | tr ',' '\n'); do echo $word; done;

should work, I tested it on command line.

Command prompt (Cmd.exe)

When the Docker CLI is used from the Windows Cmd.exe, use %cd% to mount the current directory:

echo test > test.txt
docker run --rm -v %cd%:/data busybox ls -ls /data/test.txt

Git Bash (MinGW)

When the Docker CLI is used from the Git Bash (MinGW), mounting the current directory may fail due to a POSIX path conversion: Docker mounted volume adds ;C to end of windows path when translating from linux style path.

Escape the POSIX paths by prefixing with /

To skip the path conversion, POSIX paths have to be prefixed with the slash (/) to have leading double slash (//), including /$(pwd)

touch test.txt
docker run --rm -v /$(pwd):/data busybox ls -la //data/test.txt

Disable the path conversion

Disable the POSIX path conversion in Git Bash (MinGW) by setting MSYS_NO_PATHCONV=1 environment variable at the command level

touch test.txt
MSYS_NO_PATHCONV=1 docker run --rm -v $(pwd):/data busybox ls -la /data/test.txt

or shell (system) level

export MSYS_NO_PATHCONV=1
touch test.txt
docker run --rm -v $(pwd):/data busybox ls -la /data/test.txt

If you take a look at @types/node-fetch you will see the body definition

export class Body {

    body: NodeJS.ReadableStream;
    json(): Promise<any>;
    json<T>(): Promise<T>;
    text(): Promise<string>;
    buffer(): Promise<Buffer>;
}

That means that you could use generics in order to achieve what you want. I didn't test this code, but it would looks something like this:

import { Actor } from './models/actor';

fetch(`http://swapi.co/api/people/1/`)
      .then(res => res.json<Actor>())
      .then(res => {
          let b:Actor = res;
      });

If you are getting this error while trying to use Swift class or method in Objective C: you forgot one of 2 steps Apple defined on this diagram:

Example:

Step 1: check that Test.h has

@class MyClass;

Step 2: find *-Swift.h file name in Build Settings (look for Objective-C Generated Interface Header Name). Name will be something like MyModule-Swift.h

Step 3: check that Test.m imports the above header

#import "MyModule-Swift.h"

Implicitly wait and Thread.sleep Both are used for synchronization only..but the difference is we can use Implicitly wait for entire program but Thread.sleep will works for that single code only..Here my suggestion is use Implicitly wait once in the program when every time your Webpage will get refreshed means use Thread.sleep at that time..it will much Better :)

If you compile multiple files in the same line, ensure that you use javac only once and not for every class file.

Incorrect:

Correct:

From a "sniff the network packet" point of view a GET request is safe, as the browser will first establish the secure connection and then send the request containing the GET parameters. But GET url's will be stored in the users browser history / autocomplete, which is not a good place to store e.g. password data in. Of course this only applies if you take the broader "Webservice" definition that might access the service from a browser, if you access it only from your custom application this should not be a problem.

So using post at least for password dialogs should be preferred. Also as pointed out in the link littlegeek posted a GET URL is more likely to be written to your server logs.

As an complement to Stefan Steiger answer: (as it doesn't look nice as a comment)

Extending String prototype:

String.prototype.b64encode = function() { 
    return btoa(unescape(encodeURIComponent(this))); 
};
String.prototype.b64decode = function() { 
    return decodeURIComponent(escape(atob(this))); 
};

Usage:

var str = "äöüÄÖÜçéèñ";
var encoded = str.b64encode();
console.log( encoded.b64decode() );

NOTE:

As stated in the comments, using unescape is not recommended as it may be removed in the future:

Warning: Although unescape() is not strictly deprecated (as in "removed from the Web standards"), it is defined in Annex B of the ECMA-262 standard, whose introduction states: … All of the language features and behaviours specified in this annex have one or more undesirable characteristics and in the absence of legacy usage would be removed from this specification.

Note: Do not use unescape to decode URIs, use decodeURI or decodeURIComponent instead.

I found one good thing about using bind is that you get to know the trigger event: something like: "You clicked with event = [ButtonPress event state=Mod1 num=1 x=43 y=20]" due to the code below:

self.submit.bind('<Button-1>', self.parse)
def parse(self, trigger_event):
        print("You clicked with event = {}".format(trigger_event))

Comparing the following two ways of coding a button click:

btn = Button(root, text="Click me to submit", command=(lambda: reply(ent.get())))
btn = Button(root, text="Click me to submit")
btn.bind('<Button-1>', (lambda event: reply(ent.get(), e=event)))
def reply(name, e = None):
    messagebox.showinfo(title="Reply", message = "Hello {0}!\nevent = {1}".format(name, e))

The first one is using the command function which doesn't take an argument, so no event pass-in is possible. The second one is a bind function which can take an event pass-in and print something like "Hello Charles! event = [ButtonPress event state=Mod1 num=1 x=68 y=12]"

We can left click, middle click or right click a mouse which corresponds to the event number of 1, 2 and 3, respectively. Code:

btn = Button(root, text="Click me to submit")
buttonClicks = ["<Button-1>", "<Button-2>", "<Button-3>"]
for bc in buttonClicks:
    btn.bind(bc, lambda e : print("Button clicked with event = {}".format(e.num)))

Output:

Button clicked with event = 1
Button clicked with event = 2
Button clicked with event = 3

To set an env variable in a jupyter notebook, just use a % magic commands, either %env or %set_env, e.g., %env MY_VAR=MY_VALUE or %env MY_VAR MY_VALUE. (Use %env by itself to print out current environmental variables.)

See: http://ipython.readthedocs.io/en/stable/interactive/magics.html

Here is a method to get lines between two line numbers in a file:

import sys

def file_line(name,start=1,end=sys.maxint):
    lc=0
    with open(s) as f:
        for line in f:
            lc+=1
            if lc>=start and lc<=end:
                yield line


s='/usr/share/dict/words'
l1=list(file_line(s,235880))
l2=list(file_line(s,1,10))
print l1
print l2

Output:

['Zyrian\n', 'Zyryan\n', 'zythem\n', 'Zythia\n', 'zythum\n', 'Zyzomys\n', 'Zyzzogeton\n']
['A\n', 'a\n', 'aa\n', 'aal\n', 'aalii\n', 'aam\n', 'Aani\n', 'aardvark\n', 'aardwolf\n', 'Aaron\n']

Just call it with one parameter to get from line n -> EOF

• sudo pip install keyboard

Take full control of your keyboard with this small Python library. Hook global events, register hotkeys, simulate key presses and much more.

Global event hook on all keyboards (captures keys regardless of focus). Listen and sends keyboard events. Works with Windows and Linux (requires sudo), with experimental OS X support (thanks @glitchassassin!). Pure Python, no C modules to be compiled. Zero dependencies. Trivial to install and deploy, just copy the files. Python 2 and 3. Complex hotkey support (e.g. Ctrl+Shift+M, Ctrl+Space) with controllable timeout. Includes high level API (e.g. record and play, add_abbreviation). Maps keys as they actually are in your layout, with full internationalization support (e.g. Ctrl+ç). Events automatically captured in separate thread, doesn't block main program. Tested and documented. Doesn't break accented dead keys (I'm looking at you, pyHook). Mouse support available via project mouse (pip install mouse).

From README.md:

import keyboard

keyboard.press_and_release('shift+s, space')

keyboard.write('The quick brown fox jumps over the lazy dog.')

# Press PAGE UP then PAGE DOWN to type "foobar".
keyboard.add_hotkey('page up, page down', lambda: keyboard.write('foobar'))

# Blocks until you press esc.
keyboard.wait('esc')

# Record events until 'esc' is pressed.
recorded = keyboard.record(until='esc')
# Then replay back at three times the speed.
keyboard.play(recorded, speed_factor=3)

# Type @@ then press space to replace with abbreviation.
keyboard.add_abbreviation('@@', '[email protected]')
# Block forever.
keyboard.wait()

The solution from Xavier Ho of doubling the width of the stroke and changing the paint-order is brilliant, although only works if the fill is a solid color, with no transparency.

I have developed other approach, more complicated but works for any fill. It also works in ellipses or paths (with the later there are some corner cases with strange behaviour, for example open paths that crosses theirselves, but not much).

The trick is to display the shape in two layers. One without stroke (only fill), and another one only with stroke at double width (transparent fill) and passed through a mask that shows the whole shape, but hides the original shape without stroke.

  <svg width="240" height="240" viewBox="0 0 1024 1024">
  <defs>
    <path id="ld" d="M256,0 L0,512 L384,512 L128,1024 L1024,384 L640,384 L896,0 L256,0 Z"/>
    <mask id="mask">
      <use xlink:href="#ld" stroke="#FFFFFF" stroke-width="160" fill="#FFFFFF"/>
      <use xlink:href="#ld" fill="#000000"/>
    </mask>

use a trigges it will work:-

->CREATE TRIGGER trigger_name BEFORE INSERT ON table_name

FOR EACH ROW SET NEW.column_name3 = NEW.column_name1 + NEW.column_name2;

this will only work only when you will insert a row in table not when you will be updating your table for such a pupose create another trigger of different name and use UPDATE on the place of INSERT in the above syntax

It is txtName.BackColor = System.Drawing.Color.Red;

one can also use txtName.BackColor = Color.Aqua; which is the same as txtName.BackColor = System.Color.Aqua;

Only Problem with System.color is that it does not contain a definition for some basic colors especially white, which is important cause usually textboxes are white;

If you're running Charles and trying to build a docker container then you'll most likely get this error.

Make sure to disable Charles (macos) proxy under proxy -> macOS proxy

Charles is an

HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet.

So anything similar may cause the same issue.

If You have no access to plugin for instance outside of controller You can get params from servicelocator like this

//from POST
$foo = $this->serviceLocator->get('request')->getPost('foo'); 
//from GET
$foo = $this->serviceLocator->get('request')->getQuery()->foo;
//from route
$foo = $this->serviceLocator->get('application')->getMvcEvent()->getRouteMatch()->getParam('foo');

That should do it

import time

date_time = '29.08.2011 11:05:02'
pattern = '%d.%m.%Y %H:%M:%S'
epoch = int(time.mktime(time.strptime(date_time, pattern)))
print epoch

If you like haml, but want something even better check out http://jade-lang.com for node, I wrote haml.js as well :)

The most important concern about private methods and attributes is to tell developers not to call it outside the class and this is encapsulation. one may misunderstand security from encapsulation. when one deliberately uses syntax like that(bellow) you mentioned, you do not want encapsulation.

I could have sworn there used to be a convenient fields property on a form but … Must have been my imagination.

I just do this (for <form name="my_form"></form>) because I usually don't want fieldsets themselves:

let fields = Array.from(document.forms.my_form.querySelectorAll('input, select, textarea'));

Auto-incrementing the index in a loop:

myArr[(len(myArr)+1)]={"key":"val"}

Here is how to use this in your program:

public static void main(String args[])
{
    int [] array = new int[10];

    array[0] = ((int)(Math.random()*100+1));
    array[1] = ((int)(Math.random()*100+1));
    array[2] = ((int)(Math.random()*100+1));
    array[3] = ((int)(Math.random()*100+1));
    array[4] = ((int)(Math.random()*100+1));
    array[5] = ((int)(Math.random()*100+1));
    array[6] = ((int)(Math.random()*100+1));
    array[7] = ((int)(Math.random()*100+1));
    array[8] = ((int)(Math.random()*100+1));
    array[9] = ((int)(Math.random()*100+1));

    Arrays.sort(array); 

    System.out.println(array[0] +" " + array[1] +" " + array[2] +" " + array[3]
    +" " + array[4] +" " + array[5]+" " + array[6]+" " + array[7]+" " 
    + array[8]+" " + array[9] );        

}

Converting DataTable to Generic Dictionary

public static Dictionary<object,IList<dynamic>> DataTable2Dictionary(DataTable dt)
{
    Dictionary<object, IList<dynamic>> dict = new Dictionary<dynamic, IList<dynamic>>();

    foreach(DataColumn column in dt.Columns)
    {
        IList<dynamic> ts = dt.AsEnumerable()
                              .Select(r => r.Field<dynamic>(column.ToString()))
                              .ToList();
        dict.Add(column, ts);
    }
    return dict;
}

If I understand your problem correctly, you are calling a method instead of passing it as a parameter. Try the following:

myTimer.Elapsed += PlayMusicEvent;

where

public void PlayMusicEvent(object sender, ElapsedEventArgs e)
{
    music.player.Stop();
    System.Timers.Timer myTimer = (System.Timers.Timer)sender;
    myTimer.Stop();
}

But you need to think about where to store your note.

• A GUI pops up and in that go the Corpora section, select the required corpus.
• Verified Result

This is an old post, but I ended up using Peter Lang's thoughts, and did a similar, but yet different approach. Here is what I did:

CREATE OR REPLACE FUNCTION multi_replace(
                        pString IN VARCHAR2
                        ,pReplacePattern IN VARCHAR2
) RETURN VARCHAR2 IS
    iCount  INTEGER;
    vResult VARCHAR2(1000);
    vRule   VARCHAR2(100);
    vOldStr VARCHAR2(50);
    vNewStr VARCHAR2(50);
BEGIN
    iCount := 0;
    vResult := pString;
    LOOP
        iCount := iCount + 1;

        -- Step # 1: Pick out the replacement rules
        vRule := REGEXP_SUBSTR(pReplacePattern, '[^/]+', 1, iCount);

        -- Step # 2: Pick out the old and new string from the rule
        vOldStr := REGEXP_SUBSTR(vRule, '[^=]+', 1, 1);
        vNewStr := REGEXP_SUBSTR(vRule, '[^=]+', 1, 2);

        -- Step # 3: Do the replacement
        vResult := REPLACE(vResult, vOldStr, vNewStr);

        EXIT WHEN vRule IS NULL;
    END LOOP;

    RETURN vResult;
END multi_replace;

Then I can use it like this:

SELECT  multi_replace(
                        'This is a test string with a #, a $ character, and finally a & character'
                        ,'#=%23/$=%24/&=%25'
        )
FROM dual

This makes it so that I can can any character/string with any character/string.

I wrote a post about this on my blog.

Here is an example of using super():

#New-style classes inherit from object, or from another new-style class
class Dog(object):

    name = ''
    moves = []

    def __init__(self, name):
        self.name = name

    def moves_setup(self):
        self.moves.append('walk')
        self.moves.append('run')

    def get_moves(self):
        return self.moves

class Superdog(Dog):

    #Let's try to append new fly ability to our Superdog
    def moves_setup(self):
        #Set default moves by calling method of parent class
        super(Superdog, self).moves_setup()
        self.moves.append('fly')

dog = Superdog('Freddy')
print dog.name # Freddy
dog.moves_setup()
print dog.get_moves() # ['walk', 'run', 'fly']. 
#As you can see our Superdog has all moves defined in the base Dog class

I had the same issue. by adding following lines to pom file made it work. The plugin will make sure the build process of your application with all necessary steps.

> is not in the documentation.

< is for one-way binding.

@ binding is for passing strings. These strings support {{}} expressions for interpolated values.

= binding is for two-way model binding. The model in parent scope is linked to the model in the directive's isolated scope.

& binding is for passing a method into your directive's scope so that it can be called within your directive.

When we are setting scope: true in directive, Angular js will create a new scope for that directive. That means any changes made to the directive scope will not reflect back in parent controller.

Create a "jump link" using the following format:

http://www.somesite.com/somepage#anchor

Where anchor is the id of the element you wish to link to on that page. Use browser development tools / view source to find the id of the element you wish to link to.

If the element doesnt have an id and you dont control that site then you cant do it.

You should use formControlName="surveyType" on an input and not on a div

Use open(fn, 'rb').read().decode('utf-8') instead of just open(fn).read()

Choose one you need:

>>> s = "Rajasekar SP  def"
>>> s.split(' ')
['Rajasekar', 'SP', '', 'def']
>>> s.split()
['Rajasekar', 'SP', 'def']
>>> s.partition(' ')
('Rajasekar', ' ', 'SP  def')

str.split and str.partition

Use mysql_fetch_assoc instead of mysql_fetch_array

it's valid but like UpTheCreek said 'There are some downsides to each approach'

if you're calling ajax through an tag leave the href="" like this will keep the page reloading and the ajax code will never be called ...

A man search like...

man git | grep pull | grep request

gives

git request-pull <start> <url> [<end>]

But, despite the name, it's not what you want. According to the docs:

Generate a request asking your upstream project to pull changes into their tree. The request, printed to the standard output, begins with the branch description, summarizes the changes and indicates from where they can be pulled.

@HolgerJust mentioned the github gem that does what you want:

sudo gem install gh 
gh pull-request [user] [branch]

Others have mentioned the official hub package by github:

sudo apt-get install hub

or

brew install hub 

then

hub pull-request [-focp] [-b <BASE>] [-h <HEAD>]

Instead of extrapolating off the ends, you could return the extents of the y_list. Most of the time your application is well behaved, and the Interpolate[x] will be in the x_list. The (presumably) linear affects of extrapolating off the ends may mislead you to believe that your data is well behaved.

• Returning a non-linear result (bounded by the contents of x_list and y_list) your program's behavior may alert you to an issue for values greatly outside x_list. (Linear behavior goes bananas when given non-linear inputs!)

• Returning the extents of the y_list for Interpolate[x] outside of x_list also means you know the range of your output value. If you extrapolate based on x much, much less than x_list[0] or x much, much greater than x_list[-1], your return result could be outside of the range of values you expected.

  def __getitem__(self, x):
      if x <= self.x_list[0]:
          return self.y_list[0]
      elif x >= self.x_list[-1]:
          return self.y_list[-1]
      else:
          i = bisect_left(self.x_list, x) - 1
          return self.y_list[i] + self.slopes[i] * (x - self.x_list[i])
  

fs.exists(path, callback) and fs.existsSync(path) are deprecated now, see https://nodejs.org/api/fs.html#fs_fs_exists_path_callback and https://nodejs.org/api/fs.html#fs_fs_existssync_path.

To test the existence of a file synchronously one can use ie. fs.statSync(path). An fs.Stats object will be returned if the file exists, see https://nodejs.org/api/fs.html#fs_class_fs_stats, otherwise an error is thrown which will be catched by the try / catch statement.

var fs = require('fs'),
  path = '/path/to/my/file',
  stats;

try {
  stats = fs.statSync(path);
  console.log("File exists.");
}
catch (e) {
  console.log("File does not exist.");
}

As a reference, this is how I extended the open method as per @john-macintyre's suggestion:

$.widget( "ui.dialog", $.ui.dialog, {_x000D_
 open: function() {_x000D_
  $(this.uiDialogTitlebarClose)_x000D_
   .html("<span class='ui-button-icon-primary ui-icon ui-icon-closethick'></span><span class='ui-button-text'>close</span>");_x000D_
  // Invoke the parent widget's open()._x000D_
  return this._super();_x000D_
 }_x000D_
});

You can also get your wanted time using the following JS code:

new Date(`${post.data.created_at} GMT+0200`)

In this example, my received dates were in GMT+0200 timezone. Instead of it can be every single timezone. And the returned data will be the date in your timezone. Hope this will help anyone to save time

For Python versions in 2.6+ and 3.x

You can use the str.format method. Examples:

>>> print('{0:.16f}'.format(1.6))
1.6000000000000001

>>> print('{0:.15f}'.format(1.6))
1.600000000000000

Note the 1 at the end of the first example is rounding error; it happens because exact representation of the decimal number 1.6 requires an infinite number binary digits. Since floating-point numbers have a finite number of bits, the number is rounded to a nearby, but not equal, value.

For Python versions prior to 2.6 (at least back to 2.0)

You can use the "modulo-formatting" syntax (this works for Python 2.6 and 2.7 too):

>>> print '%.16f' % 1.6
1.6000000000000001

>>> print '%.15f' % 1.6
1.600000000000000

If you want to detach existing object follow @Slauma's advice. If you want to load objects without tracking changes use:

var data = context.MyEntities.AsNoTracking().Where(...).ToList();

As mentioned in comment this will not completely detach entities. They are still attached and lazy loading works but entities are not tracked. This should be used for example if you want to load entity only to read data and you don't plan to modify them.

For a start, you have them backwards: & is reference and * is dereference.

Referencing a variable means accessing the memory address of the variable:

int i = 5;
int * p;
p = &i; //&i returns the memory address of the variable i.

Dereferencing a variable means accessing the variable stored at a memory address:

int i = 5;
int * p;
p = &i;
*p = 7; //*p returns the variable stored at the memory address stored in p, which is i.
//i is now 7

Before delete , there are several methods in laravel.

User::find(1) and User::first() return an instance.

User::where('id',1)->get and User::all() return a collection of instance.

call delete on an model instance will returns true/false

$user=User::find(1);
$user->delete(); //returns true/false

call delete on a collection of instance will returns a number which represents the number of the records had been deleted

//assume you have 10 users, id from 1 to 10;
$result=User::where('id','<',11)->delete(); //returns 11 (the number of the records had been deleted)

//lets call delete again
$result2=User::where('id','<',11)->delete(); //returns 0 (we have already delete the id<11 users, so this time we delete nothing, the result should be the number of the records had been deleted(0)  ) 

Also there are other delete methods, you can call destroy as a model static method like below

$result=User::destroy(1,2,3);
$result=User::destroy([1,2,3]);
$result=User::destroy(collect([1, 2, 3]));
//these 3 statement do the same thing, delete id =1,2,3 users, returns the number of the records had been deleted

One more thing ,if you are new to laravel ,you can use php artisan tinker to see the result, which is more efficient and then dd($result) , print_r($result);

The canonical T-SQL (SqlServer) answer is to use a DELETE with JOIN as such

DELETE o
FROM Orders o
INNER JOIN Customers c
    ON o.CustomerId = c.CustomerId
WHERE c.FirstName = 'sklivvz'

This will delete all orders which have a customer with first name Sklivvz.

What about wrapping your call in a Promise.all() method i.e.

Promise.all([$http.get(url).then(function(result){....}, function(error){....}])

According to MDN

Promise.all waits for all fulfillments (or the first rejection)

Updated for pandas 0.20 given that ix is deprecated. This demonstrates not only how to use loc, iloc, at, iat, set_value, but how to accomplish, mixed positional/label based indexing.

loc - label based
Allows you to pass 1-D arrays as indexers. Arrays can be either slices (subsets) of the index or column, or they can be boolean arrays which are equal in length to the index or columns.

Special Note: when a scalar indexer is passed, loc can assign a new index or column value that didn't exist before.

# label based, but we can use position values
# to get the labels from the index object
df.loc[df.index[2], 'ColName'] = 3

df.loc[df.index[1:3], 'ColName'] = 3

iloc - position based
Similar to loc except with positions rather that index values. However, you cannot assign new columns or indices.

# position based, but we can get the position
# from the columns object via the `get_loc` method
df.iloc[2, df.columns.get_loc('ColName')] = 3

df.iloc[2, 4] = 3

df.iloc[:3, 2:4] = 3

at - label based
Works very similar to loc for scalar indexers. Cannot operate on array indexers. Can! assign new indices and columns.

Advantage over loc is that this is faster.
Disadvantage is that you can't use arrays for indexers.

# label based, but we can use position values
# to get the labels from the index object
df.at[df.index[2], 'ColName'] = 3

df.at['C', 'ColName'] = 3

iat - position based
Works similarly to iloc. Cannot work in array indexers. Cannot! assign new indices and columns.

Advantage over iloc is that this is faster.
Disadvantage is that you can't use arrays for indexers.

# position based, but we can get the position
# from the columns object via the `get_loc` method
IBM.iat[2, IBM.columns.get_loc('PNL')] = 3

set_value - label based
Works very similar to loc for scalar indexers. Cannot operate on array indexers. Can! assign new indices and columns

Advantage Super fast, because there is very little overhead!
Disadvantage There is very little overhead because pandas is not doing a bunch of safety checks. Use at your own risk. Also, this is not intended for public use.

# label based, but we can use position values
# to get the labels from the index object
df.set_value(df.index[2], 'ColName', 3)

set_value with takable=True - position based
Works similarly to iloc. Cannot work in array indexers. Cannot! assign new indices and columns.

Advantage Super fast, because there is very little overhead!
Disadvantage There is very little overhead because pandas is not doing a bunch of safety checks. Use at your own risk. Also, this is not intended for public use.

# position based, but we can get the position
# from the columns object via the `get_loc` method
df.set_value(2, df.columns.get_loc('ColName'), 3, takable=True)

I think you're going to need separate lines for each segment:

import numpy as np
import matplotlib.pyplot as plt

x, y = np.random.random(size=(2,10))

for i in range(0, len(x), 2):
    plt.plot(x[i:i+2], y[i:i+2], 'ro-')

plt.show()

(The numpy import is just to set up some random 2x10 sample data)

Following code will solve json response if there Basic Authentication and Proxy implemented.Also IIS 7.5 Hosting Problm will resolve.

public string HttpGetByWebRequ(string uri, string username, string password)
{
//For Basic Authentication
    string authInfo = username + ":" + password;
    authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));

//For Proxy
    WebProxy proxy = new WebProxy("http://10.127.0.1:8080", true);

    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
    request.Method = "GET";
    request.Accept = "application/json; charset=utf-8";
    request.Proxy = proxy;

    request.Headers["Authorization"] = "Basic " + authInfo;

    var response = (HttpWebResponse)request.GetResponse();

    string strResponse = "";
    using (var sr = new StreamReader(response.GetResponseStream()))
    {
        strResponse= sr.ReadToEnd();

    }

    return strResponse;
}

Following the documentation of fopen:

``a'' Open for writing. The file is created if it does not exist. The stream is positioned at the end of the file. Subsequent writes to the file will always end up at the then cur- rent end of file, irrespective of any intervening fseek(3) or similar.

So if you pFile2=fopen("myfile2.txt", "a"); the stream is positioned at the end to append automatically. just do:

FILE *pFile;
FILE *pFile2;
char buffer[256];

pFile=fopen("myfile.txt", "r");
pFile2=fopen("myfile2.txt", "a");
if(pFile==NULL) {
    perror("Error opening file.");
}
else {
    while(fgets(buffer, sizeof(buffer), pFile)) {
        fprintf(pFile2, "%s", buffer);
    }
}
fclose(pFile);
fclose(pFile2);

try adding to tsconfig.json file: "noImplicitAny": false worked for me

Slight improvement on @arun-p-johny answer:

In html,

<pre id="log"></pre>

In js,

(function () {
    var old = console.log;
    var logger = document.getElementById('log');
    console.log = function () {
      for (var i = 0; i < arguments.length; i++) {
        if (typeof arguments[i] == 'object') {
            logger.innerHTML += (JSON && JSON.stringify ? JSON.stringify(arguments[i], undefined, 2) : arguments[i]) + '<br />';
        } else {
            logger.innerHTML += arguments[i] + '<br />';
        }
      }
    }
})();

Start using:

console.log('How', true, new Date());

Another conversion that uses remainders and supports different languages:

function numberToWords(number) {
  var result = [];

  var fraction = number.toFixed(2).split('.');
  var integer_part = parseInt(fraction[0]);
  // var fractional_part = parseInt(fraction[1]); -- not handled here

  var previousNumber = null;
  for (var i = 0; i < fraction[0].length; i++) {
    var reminder = Math.floor(integer_part % 10);
    integer_part /= 10;
    var name = getNumberName(reminder, i, fraction[0].length, previousNumber);
    previousNumber = reminder;
    if (name)
      result.push(name);
  }

  result.reverse();
  return result.join(' ');
}

The getNumberName function is language-dependent and handles numbers up to 9999 (but it is easy to extend it to handle larger numbers):

function getNumberName(number, power, places, previousNumber) {
  var result = "";
  if (power == 1) {
    result = handleTeensAndTys(number, previousNumber);
  } else if (power == 0 && places != 1 || number == 0) {
    // skip number that was handled in teens and zero
  } else {
    result = locale.numberNames[number.toString()] + locale.powerNames[power.toString()];
  }

  return result;
}

handleTeensAndTys handles multiples of ten:

function handleTeensAndTys(number, previousNumber) {
  var result = "";
  if (number == 1) { // teens
    if (previousNumber in locale.specialTeenNames) {
      result = locale.specialTeenNames[previousNumber];    
    } else if (previousNumber in locale.specialTyNames) {
      result = locale.specialTyNames[previousNumber] + locale.teenSuffix;
    } else {
      result = locale.numberNames[previousNumber] + locale.teenSuffix;    
    }
  } else if (number == 0) { // previousNumber was not handled in teens
    result = locale.numberNames[previousNumber.toString()];
  } else { // other tys
    if (number in locale.specialTyNames) {
      result = locale.specialTyNames[number];
    } else {
      result = locale.numberNames[number];
    }
    result += locale.powerNames[1];
    if (previousNumber != 0) {
      result += " " + locale.numberNames[previousNumber.toString()];
    }
  }
  return result;
}

Finally, locale examples:

var locale = { // English
  numberNames: {1: "one", 2: "two", 3: "three", 4: "four", 5: "five", 6: "six", 7: "seven", 8: "eight", 9: "nine" },
  powerNames: {0: "", 1: "ty", 2: " hundred", 3: " thousand" },
  specialTeenNames: {0: "ten", 1: "eleven", 2: "twelve" },
  specialTyNames: {2: "twen", 3: "thir", 5: "fif" },
  teenSuffix: "teen"
};

var locale = { // Estonian
  numberNames: {1: "üks", 2: "kaks", 3: "kolm", 4: "neli", 5: "viis", 6: "kuus", 7: "seitse", 8: "kaheksa", 9: "üheksa"},
  powerNames: {0: "", 1: "kümmend", 2: "sada", 3: " tuhat" },
  specialTeenNames: {0: "kümme"},
  specialTyNames: {},
  teenSuffix: "teist"
};

Here's a JSFiddle with tests: https://jsfiddle.net/rcrxna7v/15/

I had the same error on a page, and I added these lines:

You could create a Scheduler Task that runs automatically on the start, even when the user is not logged in:

schtasks /create /tn "FileMonitor" /sc onstart /delay 0000:30 /rl highest /ru system /tr "powershell.exe -file C:\Doc\Files\FileMonitor.ps1"

Run this command once from a PowerShell as Admin and it will create a schedule task for you. You can list the task like this:

schtasks /Query /TN "FileMonitor" /V /FO List

or delete it

schtasks /Delete /TN "FileMonitor"

This is the command for the batch file and it can run the vbscript.

C:\Windows\SysWOW64\cmd.exe /c cscript C:\Windows\SysWOW64\...\necdaily.vbs

It appears this can be done. I'm unable to determine the version of GCC that it was added, but it was sometime before June 2010.

Here's an example:

#pragma GCC diagnostic error "-Wuninitialized"
    foo(a);         /* error is given for this one */
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wuninitialized"
    foo(b);         /* no diagnostic for this one */
#pragma GCC diagnostic pop
    foo(c);         /* error is given for this one */
#pragma GCC diagnostic pop
    foo(d);         /* depends on command line options */

You should be escaping each of these strings (in both snippets) with mysql_real_escape_string().

http://us3.php.net/mysql-real-escape-string

The reason your two queries are behaving differently is likely because you have magic_quotes_gpc turned on (which you should know is a bad idea). This means that strings gathered from $_GET, $_POST and $_COOKIES are escaped for you (i.e., "O'Brien" -> "O\'Brien").

Once you store the data, and subsequently retrieve it again, the string you get back from the database will not be automatically escaped for you. You'll get back "O'Brien". So, you will need to pass it through mysql_real_escape_string().

Imagine you have a numpy array of integers (it works with other types but you need some slight modification). You can do this:

a = np.array([0, 3, 5])
a_str = ','.join(str(x) for x in a) # '0,3,5'
a2 = np.array([int(x) for x in a_str.split(',')]) # np.array([0, 3, 5])

If you have an array of float, be sure to replace int by float in the last line.

You can also use the __repr__() method, which will have the advantage to work for multi-dimensional arrays:

from numpy import array
numpy.set_printoptions(threshold=numpy.nan)
a = array([[0,3,5],[2,3,4]])
a_str = a.__repr__() # 'array([[0, 3, 5],\n       [2, 3, 4]])'
a2 = eval(a_str) # array([[0, 3, 5],
                 #        [2, 3, 4]])

You can use String.split(String regex):

String input = "aabbab";
String[] parts = input.split("(?!^)");

Storage Location for Unpacked Extensions

Extension engine does not explicitly change their location or add a reference to its local paths, they are left in the place where there are selected from in all Operating Systems.

Ex: If i load a unpacked Extension from E:\Chrome Extension the unpacked Extension is still in the same location

Storage Location for Packed Extensions

Navigate to chrome://version/ and look for Profile Path, it is your default directory and Extensions Folder is where all the extensions, apps, themes are stored

Ex:

Windows

If my Profile Path is %userprofile%\AppData\Local\Google\Chrome\User Data\Default then my storage directory is:

C:\Users\<Your_User_Name>\AppData\Local\Google\Chrome\User Data\Default\Extensions 

Linux

~/.config/google-chrome/Default/Extensions/

MacOS

~/Library/Application\ Support/Google/Chrome/Default/Extensions

Chromium

~/.config/chromium/Default/Extensions

When you overload in TypeScript, you only have one implementation with multiple signatures.

class Foo {
    myMethod(a: string);
    myMethod(a: number);
    myMethod(a: number, b: string);
    myMethod(a: any, b?: string) {
        alert(a.toString());
    }
}

Only the three overloads are recognized by TypeScript as possible signatures for a method call, not the actual implementation.

In your case, I would personally use two methods with different names as there isn't enough commonality in the parameters, which makes it likely the method body will need to have lots of "ifs" to decide what to do.

TypeScript 1.4

As of TypeScript 1.4, you can typically remove the need for an overload using a union type. The above example can be better expressed using:

myMethod(a: string | number, b?: string) {
    alert(a.toString());
}

The type of a is "either string or number".

$$ is defined to return the process ID of the parent in a subshell; from the man page under "Special Parameters":

$ Expands to the process ID of the shell. In a () subshell, it expands to the process ID of the current shell, not the subshell.

In bash 4, you can get the process ID of the child with BASHPID.

~ $ echo $$
17601
~ $ ( echo $$; echo $BASHPID )
17601
17634

go to "Project-Properties-Configuration Properties-Linker-input-Additional dependencies" then go to the end and type ";ws2_32.lib".

Give an ID to uniquely identify the button, lets say myBtn

// when DOM is ready
$(document).ready(function () {

     // Attach Button click event listener 
    $("#myBtn").click(function(){

         // show Modal
         $('#myModal').modal('show');
    });
});

The Jackson-databind library also has ISO8601DateFormat class that does that (actual implementation in ISO8601Utils.

ISO8601DateFormat df = new ISO8601DateFormat();
Date d = df.parse("2010-07-28T22:25:51Z");

We can use contains method to check if an item exists if we have provided the implementation of equals and hashCode else object reference will be used for equality comparison. Also in case of a list contains is O(n) operation where as it is O(1) for HashSet so better to use later. In Java 8 we can use streams also to check item based on its equality or based on a specific property.

Java 8

CurrentAccount conta5 = new CurrentAccount("João Lopes", 3135);
boolean itemExists = lista.stream().anyMatch(c -> c.equals(conta5)); //provided equals and hashcode overridden
System.out.println(itemExists); // true

String nameToMatch = "Ricardo Vitor";
boolean itemExistsBasedOnProp = lista.stream().map(CurrentAccount::getName).anyMatch(nameToMatch::equals);
System.out.println(itemExistsBasedOnProp); //true

Template:

{% block content %}
    <div id="content">
        <h1>Hi there!</h1>
    </div>

If you want to use django-easy-pdf on Python 3 check the solution suggested here.

Here is my reason:

before:

var path = "D:\xxx\util.s"

which \u is a escape, I figured it out by using Codepen's analyze JS.

after:

var path = "D:\\xxx\\util.s"

and the error fixed

You should use the class name like this

$(document).ready(function(){
    $('input.addCheck').prop('checked',true);
});

From the CLI:

php -r 'phpinfo();'

I found out that single quote > double quote > wrapped in ampersands did work. So, for me it looks like this:

=QUERY('Youth Conference Registration'!C:Y,"select C where Y = '"&A1&"'", 0)

Are you sure the page you are redirecting too doesn't have a redirection within that if no session data is found? That could be your problem

Also yes always add whitespace like @Peter O suggested.

Instead of

css=#container

use

css=div.container:nth-of-type(1),css=div.container:nth-of-type(2)

Facebook prefers that you load their SDK asynchronously so that it doesn't block any other scripts that you need for your page but due to the iframe there's a chance that the console tries to call a method on the FB object before the FB object is completely created even though FB is only called in the fbAsyncInit function.
Try loading the javascript synchronously and you shouldn't get the error anymore. To do this you can copy and paste the code that Facebook provides and place it in an external .js file and then include that .js file in a <script> tag in the <head> of your page. If you must load their SDK asynchronously then check for FB to be created first before calling the init function.

Without unplugging

All the provided answers assume that you are able to unplug and reconnect the USB cable. In situations where this is not possible (e.g., when you are remote), you can do the following to essentially do what the suggested udev rules would do on re-plug:

lsusb

Find the device you care about, e.g.:

Bus 003 Device 005: ID 18d1:4ee4 Google Inc. Nexus

Take note of the bus number it is on and then execute, e.g. for bus 003:

sudo chmod a+w /dev/bus/usb/003/*

Clearly this may be more permissive than you want (there may be more devices attached than just this one), but you get the idea.

Probably part of Open Graph Protocol for Facebook.

Edit: guess not only Facebook - that's only one example of using it.

Use this function: http://br.php.net/json_decode This will automatically create PHP arrays.

a and b must both be sets of the same type. But nothing prevents you from writing

myfunction(Set<X> a, Set<Y> b)

You cannot get the exact code, but you can get a decompiled version of it.

The most popular (and best) tool is Reflector, but there are also other .Net decompilers (such as Dis#). You can also decompile the IL using ILDASM, which comes bundled with the .Net Framework SDK Tools.

Let me try this with an example:

Regex Code: (?:animal)(?:=)(\w+)(,)\1\2

Search String:

Line 1 - animal=cat,dog,cat,tiger,dog

Line 2 - animal=cat,cat,dog,dog,tiger

Line 3 - animal=dog,dog,cat,cat,tiger

(?:animal) --> Non-Captured Group 1

(?:=)--> Non-Captured Group 2

(\w+)--> Captured Group 1

(,)--> Captured Group 2

\1 --> result of captured group 1 i.e In Line 1 is cat, In Line 2 is cat, In Line 3 is dog.

\2 --> result of captured group 2 i.e comma (,)

So in this code by giving \1 and \2 we recall or repeat the result of captured group 1 and 2 respectively later in the code.

As per the order of code (?:animal) should be group 1 and (?:=) should be group 2 and continues..

but by giving the ?: we make the match-group non captured (which do not count off in matched group, so the grouping number starts from the first captured group and not the non captured), so that the repetition of the result of match-group (?:animal) can't be called later in code.

Hope this explains the use of non capturing group.

That 2GB limit you see is the total memory of the VM in which docker runs.

If you are using docker-for-windows or docker-for-mac you can easily increase it from the Whale icon in the task bar, then go to Preferences -> Advanced:

But if you are using VirtualBox behind, open VirtualBox, Select and configure the docker-machine assigned memory.

See this for Mac:

https://docs.docker.com/docker-for-mac/#memory

MEMORY By default, Docker for Mac is set to use 2 GB runtime memory, allocated from the total available memory on your Mac. You can increase the RAM on the app to get faster performance by setting this number higher (for example to 3) or lower (to 1) if you want Docker for Mac to use less memory.

For Windows:

I found another reason for this type of error: in my case, someone set the conf/catalina.properties setting tomcat.util.scan.StandardJarScanFilter.jarsToSkip property to * to avoid log warning messages, thereby skipping the necessary scan by Tomcat. Changing this back to the Tomcat default and adding an appropriate list of jars to skip (not including jstl-1.2 or spring-webmvc) solved the problem.

The default condition can be anyplace within the switch that a case clause can exist. It is not required to be the last clause. I have seen code that put the default as the first clause. The case 2: gets executed normally, even though the default clause is above it.

As a test, I put the sample code in a function, called test(int value){} and ran:

  printf("0=%d\n", test(0));
  printf("1=%d\n", test(1));
  printf("2=%d\n", test(2));
  printf("3=%d\n", test(3));
  printf("4=%d\n", test(4));

The output is:

0=2
1=1
2=4
3=8
4=10

The most simple and the correct way is to use Record type Record<string, string>

const myVar : Record<string, string> = {
   key1: 'val1',
   key2: 'val2',
}

If you have more than one view in the layout file android.R.layout.simple_list_item_1 then you'll have to pass the third argument android.R.id.text1 to specify the view that should be filled with the array elements (values). But if you have just one view in your layout file, there is no need to specify the third argument.

You could use:

List<String> tokens = Arrays.stream(s.split("\\s+")).collect(Collectors.toList());

You should ask yourself if you really need the ArrayList in the first place. Very often, you're going to filter the list based on additional criteria, for which a Stream is perfect. You may want a set; you may want to filter them by means of another regular expression, etc. Java 8 provides this very useful extension, by the way, which will work on any CharSequence: https://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html#splitAsStream-java.lang.CharSequence-. Since you don't need the array at all, avoid creating it thus:

// This will presumably be a static final field somewhere.
Pattern splitter = Pattern.compile("\\s+");
// ...
String untokenized = reader.readLine();
Stream<String> tokens = splitter.splitAsStream(untokenized);

I like Clay Eclipse plugin. I've only used it with MySQL, but it claims Firebird support.

Make sure you're in the right directory (repository main folder) in your local git so it can find .git folder configuration before you commit or add files.

class StudentAdapter extends BaseAdapter {
    ArrayList<LichHocDTO> studentList;

    private void capNhatDuLieu(ArrayList<LichHocDTO> list){
        this.studentList.clear();
        this.studentList.addAll(list);
        this.notifyDataSetChanged();
    }
}

You can try. It work for me

I created a PHP class for this with a corresponding jQuery plugin. I've open-sourced it at https://github.com/peterjtracey/timezoneWidget - the PHP code is inspired by another stackoverflow answer, but I think much more elegant. The jQuery plugin gives a great interface for selecting a timezone.

I landed here because of an XCTestCase, in which I'd disabled most of the tests by prefixing them with 'no_' as in no_testBackgroundAdding. Once I noticed that most of the answers had something to do with locks and threading, I realized the test contained a few instances of XCTestExpectation with corresponding waitForExpectations. They were all in the disabled tests, but apparently Xcode was still evaluating them at some level.

In the end I found an XCTestExpectation that was defined as @property but lacked the @synthesize. Once I added the synthesize directive, the EXC_BAD_INSTRUCTION disappeared.

Now for the error:

1.Make sure that you have enough Processor(s) and Base Memory - so the PC can support VM configuration(I use 1 procesor and 1024MB for all VM's)

2.Delete any unused VM from Genymotion and Oracle VirtualBox Manager - seems to reserve their configuration, though you use it or not(that specific VM)

Also see: the official Which remote URL should I use? answer on help.github.com.

EDIT:

It seems that it's no longer necessary to have write access to a public repo to use an SSH URL, rendering my original explanation invalid.

ORIGINAL:

Apparently the main reason for favoring HTTPS URLs is that SSH URL's won't work with a public repo if you don't have write access to that repo.

The use of SSH URLs is encouraged for deployment to production servers, however - presumably the context here is services like Heroku.

This type of error also takes place because the resize is unable to get the image in simple the directory of the image may be wrong.In my case I left the forward slash during providing the location of file and this error took place after I put the slash problem was solved.

In my case i had only one EditText to manage in my layout so i came up whit this solution. It works well, basically it is a custom EditText which listens for focus and sends a local broadcast if the focus changes or if the back/done button is pressed. To work you need to place a dummy View in your layout with android:focusable="true" and android:focusableInTouchMode="true" because when you call clearFocus() the focus will be reassigned to the first focusable view. Example of dummy view:

<View
android:layout_width="1dp"
android:layout_height="1dp"
android:focusable="true"
android:focusableInTouchMode="true"/>

Additional infos

The solution which detects the difference in layout changes doesn't work very well because it strongly depends on screen density, since 100px can be a lot in a certain device and nothing in some others you could get false positives. Also different vendors have different keyboards.

This link has answers to the same basic question, but basically, id is used for scripting identification and name is for server-side.
