You could use extension methods to make it a little more readable:

public static class DateTimeExtensions
{
    public static bool InRange(this DateTime dateToCheck, DateTime startDate, DateTime endDate)
    {
        return dateToCheck >= startDate && dateToCheck < endDate;
    }
}

Now you can write:

dateToCheck.InRange(startDate, endDate)

I use moment.js and Twix.js they provide a very great support for date and time manpulation

var itr = moment.twix(new Date('2012-01-15'),new Date('2012-01-20')).iterate("days");
var range=[];
while(itr.hasNext()){
    range.push(itr.next().toDate())
}
console.log(range);

I have this running on http://jsfiddle.net/Lkzg1bxb/

SELECT * 
FROM events 
WHERE start <= '2013-07-22' OR end >= '2013-06-13'

Use the DateTime class if you have PHP 5.3+. Easier to use, better functionality.

DateTime internally supports timezones, with the other solutions is up to you to handle that.

<?php    
/**
 * @param DateTime $date Date that is to be checked if it falls between $startDate and $endDate
 * @param DateTime $startDate Date should be after this date to return true
 * @param DateTime $endDate Date should be before this date to return true
 * return bool
 */
function isDateBetweenDates(DateTime $date, DateTime $startDate, DateTime $endDate) {
    return $date > $startDate && $date < $endDate;
}

$fromUser = new DateTime("2012-03-01");
$startDate = new DateTime("2012-02-01 00:00:00");
$endDate = new DateTime("2012-04-30 23:59:59");

echo isDateBetweenDates($fromUser, $startDate, $endDate);

If startDate and endDate are indeed date objects you could convert them to number of milliseconds since midnight Jan 1, 1970, like this:

var startTime = startDate.getTime(), endTime = endDate.getTime();

Then you could loop from one to another incrementing loopTime by 86400000 (1000*60*60*24) - number of milliseconds in one day:

for(loopTime = startTime; loopTime < endTime; loopTime += 86400000)
{
    var loopDay=new Date(loopTime)
    //use loopDay as you wish
}

$arr = range(strtotime("2013-12-01"),strtotime("2013-12-31"), "86400");
array_walk_recursive($arr, function(&$element) { $element = date("Y-m-d", $element); });
print_r ($arr);

Your question didnt ask how to use BETWEEN correctly, rather asked for help with the unexpectedly truncated results...

As mentioned/hinting at in the other answers, the problem is that you have time segments in addition to the dates.

In my experience, using date diff is worth the extra wear/tear on the keyboard. It allows you to express exactly what you want, and you are covered.

select * 
from xxx 
where datediff(d, '2012-10-26', dates) >=0
and  datediff(d, dates,'2012-10-27') >=0

using datediff, if the first date is before the second date, you get a positive number. There are several ways to write the above, for instance always having the field first, then the constant. Just flipping the operator. Its a matter of personal preference.

you can be explicit about whether you want to be inclusive or exclusive of the endpoints by dropping one or both equal signs.

BETWEEN will work in your case, because the endpoints are both assumed to be midnight (ie DATEs). If your endpoints were also DATETIME, using BETWEEN may require even more casting. In my mind DATEDIFF was put in our lives to insulate us from those issues.

raise without any arguments is a special use of python syntax. It means get the exception and re-raise it. If this usage it could have been called reraise.

    raise

From The Python Language Reference:

If no expressions are present, raise re-raises the last exception that was active in the current scope.

If raise is used alone without any argument is strictly used for reraise-ing. If done in the situation that is not at a reraise of another exception, the following error is shown: RuntimeError: No active exception to reraise

If 'Favorite' is measured by how often I use it, then:

The Flutter SDK path is certainly defined in a place where you can check it or change it, whether you created the project or not. Under Settings > Languages & Frameworks there should be a Flutter section. I found it by using the handy search bar in the Settings menu.

At the top of the Languages & Frameworks > Flutter is the Flutter SDK Path.

This is assuming that Flutter/Dart have already been installed under Plugins.

There is no tuple type in Go, and you are correct, the multiple values returned by functions do not represent a first-class object.

Nick's answer shows how you can do something similar that handles arbitrary types using interface{}. (I might have used an array rather than a struct to make it indexable like a tuple, but the key idea is the interface{} type)

My other answer shows how you can do something similar that avoids creating a type using anonymous structs.

These techniques have some properties of tuples, but no, they are not tuples.

Please note that the tr -s ' ' option will not remove any single leading spaces. If your column is right-aligned (as with ps pid)...

$ ps h -o pid,user -C ssh,sshd | tr -s " "
 1543 root
19645 root
19731 root

Then cutting will result in a blank line for some of those fields if it is the first column:

$ <previous command> | cut -d ' ' -f1

19645
19731

Unless you precede it with a space, obviously

$ <command> | sed -e "s/.*/ &/" | tr -s " "

Now, for this particular case of pid numbers (not names), there is a function called pgrep:

$ pgrep ssh

Shell functions

However, in general it is actually still possible to use shell functions in a concise manner, because there is a neat thing about the read command:

$ <command> | while read a b; do echo $a; done

The first parameter to read, a, selects the first column, and if there is more, everything else will be put in b. As a result, you never need more variables than the number of your column +1.

So,

while read a b c d; do echo $c; done

will then output the 3rd column. As indicated in my comment...

A piped read will be executed in an environment that does not pass variables to the calling script.

out=$(ps whatever | { read a b c d; echo $c; })

arr=($(ps whatever | { read a b c d; echo $c $b; }))
echo ${arr[1]}     # will output 'b'`

The Array Solution

So we then end up with the answer by @frayser which is to use the shell variable IFS which defaults to a space, to split the string into an array. It only works in Bash though. Dash and Ash do not support it. I have had a really hard time splitting a string into components in a Busybox thing. It is easy enough to get a single component (e.g. using awk) and then to repeat that for every parameter you need. But then you end up repeatedly calling awk on the same line, or repeatedly using a read block with echo on the same line. Which is not efficient or pretty. So you end up splitting using ${name%% *} and so on. Makes you yearn for some Python skills because in fact shell scripting is not a lot of fun anymore if half or more of the features you are accustomed to, are gone. But you can assume that even python would not be installed on such a system, and it wasn't ;-).

Useful differences:

• Use notify() if all your waiting threads are interchangeable (the order they wake up doesn't matter), or if you only ever have one waiting thread. A common example is a thread pool used to execute jobs from a queue--when a job is added, one of threads is notified to wake up, execute the next job and go back to sleep.

• Use notifyAll() for other cases where the waiting threads may have different purposes and should be able to run concurrently. An example is a maintenance operation on a shared resource, where multiple threads are waiting for the operation to complete before accessing the resource.

It the element has two xpath. Then you can write two xpaths like below:

xpath1 | xpath2

Eg:

//input[@name="username"] | //input[@id="wm_login-username"]

EDIT: I am maintaining a similar, but more in-depth answer at: https://stackoverflow.com/a/28380690/895245

To see exactly what is happening, use nc -l or an ECHO server and an user agent like a browser or cURL.

Save the form to an .html file:

<form action="http://localhost:8000" method="post" enctype="multipart/form-data">
  <p><input type="text" name="text" value="text default">
  <p><input type="file" name="file1">
  <p><input type="file" name="file2">
  <p><button type="submit">Submit</button>
</form>

Create files to upload:

echo 'Content of a.txt.' > a.txt
echo '<!DOCTYPE html><title>Content of a.html.</title>' > a.html

Run:

nc -l localhost 8000

Open the HTML on your browser, select the files and click on submit and check the terminal.

nc prints the request received. Firefox sent:

Aternativelly, cURL should send the same POST request as your a browser form:

nc -l localhost 8000
curl -F "text=default" -F "[email protected]" -F "[email protected]" localhost:8000

You can do multiple tests with:

while true; do printf '' | nc -l localhost 8000; done

Check Class.java source code for equals()

public boolean equals(Object obj) {
  return this == obj;
}

I'd like to recommend var_export($array) - it doesn't show types, but it generates syntax you can use in your code :)

If you want to select the file or folder you can use the following:

Process.Start("explorer.exe", "/select, c:\\teste");

With fscanf read the file until you encounter ';' or \n, then you can just skip it with fscang(f, "%*c").

int main()
{
    char str[128];
    int result;
    FILE* f = fopen("test.txt", "r");
    ...
    
    do {
        result = fscanf(f, "%127[^;\n]", str);
        
        if(result == 0)
        {
            result = fscanf(f, "%*c");
        }
        else
        {
            //whatever you want to do with your value
            printf("%s\n", str);
        }
        
    } while(result != EOF);

    return 0;
}

SELECT Id   'PatientId',
       ISNULL(CONVERT(varchar(50),ParentId),'')  'ParentId'
FROM Patients

ISNULL always tries to return a result that has the same data type as the type of its first argument. So, if you want the result to be a string (varchar), you'd best make sure that's the type of the first argument.

COALESCE is usually a better function to use than ISNULL, since it considers all argument data types and applies appropriate precedence rules to determine the final resulting data type. Unfortunately, in this case, uniqueidentifier has higher precedence than varchar, so that doesn't help.

(It's also generally preferred because it extends to more than two arguments)

private JSONObject uploadToServer() throws IOException, JSONException {
            String query = "https://example.com";
            String json = "{\"key\":1}";

            URL url = new URL(query);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setConnectTimeout(5000);
            conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
            conn.setDoOutput(true);
            conn.setDoInput(true);
            conn.setRequestMethod("POST");

            OutputStream os = conn.getOutputStream();
            os.write(json.getBytes("UTF-8"));
            os.close();

            // read the response
            InputStream in = new BufferedInputStream(conn.getInputStream());
            String result = org.apache.commons.io.IOUtils.toString(in, "UTF-8");
            JSONObject jsonObject = new JSONObject(result);


            in.close();
            conn.disconnect();

            return jsonObject;
    }

On StackOverflow, pressing the up-vote button is AJAX whereas typing in your question or answer and seeing it appear in the real-time preview window below it is JavaScript (JQuery).

This means that the difference between AJAX and Javascript is that AJAX allows you to communicate with the server without doing a page refresh (i.e. going to a new page) whereas JavaScript (JQuery) allows you to embed logic and behaviour on your page. Of course, with this logic you create AJAX as well.

The standard solution didn't work for me, when changing the type from TEXT to LONGTEXT.

I had to it like this:

public function up()
{
    DB::statement('ALTER TABLE mytable MODIFY mycolumn  LONGTEXT;');
}

public function down()
{
    DB::statement('ALTER TABLE mytable MODIFY mycolumn TEXT;');
}

This could be a Doctrine issue. More information here.

Another way to do it is to use the string() method, and set the value to the text type max length:

    Schema::table('mytable', function ($table) {
        // Will set the type to LONGTEXT.
        $table->string('mycolumn', 4294967295)->change();
    });

any one try this

    (function () {  
        var  
         form = $('.form'),  
         cache_width = form.width(),  
         a4 = [595.28, 841.89]; // for a4 size paper width and height  

        $('#create_pdf').on('click', function () {  
            $('body').scrollTop(0);  
            createPDF();  
        });  
        //create pdf  
        function createPDF() {  
            getCanvas().then(function (canvas) {  
                var  
                 img = canvas.toDataURL("image/png"),  
                 doc = new jsPDF({  
                     unit: 'px',  
                     format: 'a4'  
                 });  
                doc.addImage(img, 'JPEG', 20, 20);  
                doc.save('Bhavdip-html-to-pdf.pdf');  
                form.width(cache_width);  
            });  
        }  

        // create canvas object  
        function getCanvas() {  
            form.width((a4[0] * 1.33333) - 80).css('max-width', 'none');  
            return html2canvas(form, {  
                imageTimeout: 2000,  
                removeContainer: true  
            });  
        }  

    }());  

You can also do this in a .htaccess file assuming they are enabled on the website.

SetEnv KOHANA_ENV production

Would be all you need to add to a .htaccess to add the environment variable

The multiline flag tells regex to match the pattern to each line as opposed to the entire string for your purposes a wild card will suffice.

We're planning to use FitNesse, with the RestFixture. We haven't started writing our tests yet, our newest tester got things up and running last week, however he has used FitNesse for this in his last company, so we know it's a reasonable setup for what we want to do.

More info available here: http://smartrics.blogspot.com/2008/08/get-fitnesse-with-some-rest.html

You can also try the following project that aims to help use that api. It's here:https://github.com/MathiasSeguy-Android2EE/GDirectionsApiUtils

How it works, definitly simply:

public class MainActivity extends ActionBarActivity implements DCACallBack{
/**
 * Get the Google Direction between mDevice location and the touched location using the     Walk
 * @param point
 */
private void getDirections(LatLng point) {
     GDirectionsApiUtils.getDirection(this, mDeviceLatlong, point,     GDirectionsApiUtils.MODE_WALKING);
}

/*
 * The callback
 * When the direction is built from the google server and parsed, this method is called and give you the expected direction
 */
@Override
public void onDirectionLoaded(List<GDirection> directions) {        
    // Display the direction or use the DirectionsApiUtils
    for(GDirection direction:directions) {
        Log.e("MainActivity", "onDirectionLoaded : Draw GDirections Called with path " + directions);
        GDirectionsApiUtils.drawGDirection(direction, mMap);
    }
}

Did you try?

 protect_from_forgery with: :null_session, if: Proc.new {|c| c.request.format.json? }

Try this:

<td>
    <a onclick="return confirm(\'Are you sure?\');" href="'.base_url('category/delete_category/'.$row->category_id).'" class="btn btn-danger btn-sm"><i class="fa fa-trash"></i> Delete Coupon</a>
</td>

There are a few ways to handle that; Vanilla JavaScript can do it quite nicely:

function code(e) {
    e = e || window.event;
    return(e.keyCode || e.which);
}
window.onload = function(){
    document.onkeypress = function(e){
        var key = code(e);
        // do something with key
    };
};

Or a more structured way of handling it:

(function(d){
    var modern = (d.addEventListener), event = function(obj, evt, fn){
        if(modern) {
            obj.addEventListener(evt, fn, false);
        } else {
            obj.attachEvent("on" + evt, fn);
        }
    }, code = function(e){
        e = e || window.event;
        return(e.keyCode || e.which);
    }, init = function(){
        event(d, "keypress", function(e){
            var key = code(e);
            // do stuff with key here
        });
    };
    if(modern) {
        d.addEventListener("DOMContentLoaded", init, false);
    } else {
        d.attachEvent("onreadystatechange", function(){
            if(d.readyState === "complete") {
                init();
            }
        });
    }
})(document);

I try to keep my dependencies to a minimum, so I implemented this myself instead of going with EventToCommand of MVVMLight. Works for me so far, but feedback is welcome.

Xaml:

<i:Interaction.Behaviors>
    <beh:EventToCommandBehavior Command="{Binding DropCommand}" Event="Drop" PassArguments="True" />

Convert PPK to OpenSSh

OS X: Install Homebrew, then run

brew install putty

Place your keys in some directory, e.g. your home folder. Now convert the PPK keys to SSH keypairs:cache search

To generate the private key:

cd ~

puttygen id_dsa.ppk -O private-openssh -o id_dsa

and to generate the public key:

puttygen id_dsa.ppk -O public-openssh -o id_dsa.pub

Move these keys to ~/.ssh and make sure the permissions are set to private for your private key:

mkdir -p ~/.ssh
mv -i ~/id_dsa* ~/.ssh
chmod 600 ~/.ssh/id_dsa
chmod 666 ~/.ssh/id_dsa.pub

connect with ssh server

ssh -i ~/.ssh/id_dsa username@servername

Port Forwarding to connect mysql remote server

ssh -i ~/.ssh/id_dsa -L 9001:127.0.0.1:3306 username@serverName

From the pthread function prototype:

int pthread_create(pthread_t *thread, const pthread_attr_t *attr,

Android's Java API does not support javax.naming.* and many other javax.* stuff. You need to include the dependencies as separate jars.

I have the same error and it fixed it including in the file the following

#include <stdint.h>

at the beginning of your file.

You could just pass an anchor tag without an href property, and use jQuery to do the required action:

<a class="foo">bar</a>

That is a problem of security protocol. I am using TLSv1 but the host accept only TLSv1.1 and TLSv1.2 then I changed the protocol in Java with the instruction below:

System.setProperty("https.protocols", "TLSv1.1");

Although systemd indeed does not provide way to pass command-line arguments for unit files, there are possibilities to write instances: http://0pointer.de/blog/projects/instances.html

For example: /lib/systemd/system/[email protected] looks something like this:

[Unit]
Description=Serial Getty on %I
BindTo=dev-%i.device
After=dev-%i.device systemd-user-sessions.service

[Service]
ExecStart=-/sbin/agetty -s %I 115200,38400,9600
Restart=always
RestartSec=0

So, you may start it like:

$ systemctl start [email protected]
$ systemctl start [email protected]

For systemd it will different instances:

$ systemctl status [email protected]
[email protected] - Getty on ttyUSB0
      Loaded: loaded (/lib/systemd/system/[email protected]; static)
      Active: active (running) since Mon, 26 Sep 2011 04:20:44 +0200; 2s ago
    Main PID: 5443 (agetty)
      CGroup: name=systemd:/system/[email protected]/ttyUSB0
          + 5443 /sbin/agetty -s ttyUSB0 115200,38400,9600

It also mean great possibility enable and disable it separately.

Off course it lack much power of command line parsing, but in common way it is used as some sort of config files selection. For example you may look at Fedora [email protected]: http://pkgs.fedoraproject.org/cgit/openvpn.git/tree/[email protected]

Based on icecrime's answer I wrote this function

std::vector<int> intToDigits(int num_)
{
    std::vector<int> ret;
    string iStr = to_string(num_);

    for (int i = iStr.size() - 1; i >= 0; --i)
    {
        int units = pow(10, i);
        int digit = num_ / units % 10;
        ret.push_back(digit);
    }   

    return ret;
}

For first and last names theres are really only 2 things you should be looking for:

1. Length
2. Content

Here is my regular expression:

var regex = /^[A-Za-z-,]{3,20}?=.*\d)/

1. Length

Here the {3,20} constrains the length of the string to be between 3 and 20 characters.

2. Content

The information between the square brackets [A-Za-z] allows uppercase and lowercase characters. All subsequent symbols (-,.) are also allowed.

To do this for a specific target, you can do the following:

target_compile_definitions(my_target PRIVATE FOO=1 BAR=1)

You should do this if you have more than one target that you're building and you don't want them all to use the same flags. Also see the official documentation on target_compile_definitions.

Use this:

\d{10}

I hope it helps.

My answer to a similar question is accounting for ties too and it is in plain Javascript, although it doesn't use binary search so it is O(N) and not O(logN):

var searchArray= [0, 30, 60, 90];
var element= 33;

function findClosest(array,elem){
    var minDelta = null;
    var minIndex = null;
    for (var i = 0 ; i<array.length; i++){
        var delta = Math.abs(array[i]-elem);
        if (minDelta == null || delta < minDelta){
            minDelta = delta;
            minIndex = i;
        }
        //if it is a tie return an array of both values
        else if (delta == minDelta) {
            return [array[minIndex],array[i]];
        }//if it has already found the closest value
        else {
            return array[i-1];
        }

    }
    return array[minIndex];
}
var closest = findClosest(searchArray,element);

I wanted a solution to have the output from stdout plus stderr written into a log file and stderr still on console. So I needed to duplicate the stderr output via tee.

This is the solution I found:

command 3>&1 1>&2 2>&3 1>>logfile | tee -a logfile

• First swap stderr and stdout
• then append the stdout to the log file
• pipe stderr to tee and append it also to the log file

This is a feature called template literals.

They were called "template strings" in prior editions of the ECMAScript 2015 specification.

Template literals are supported by Firefox 34, Chrome 41, and Edge 12 and above, but not by Internet Explorer.

• Examples: http://tc39wiki.calculist.org/es6/template-strings/
• Official specification: ECMAScript 2015 Language Specification, 12.2.9 Template Literal Lexical Components (a bit dry)

Template literals can be used to represent multi-line strings and may use "interpolation" to insert variables:

var a = 123, str = `---
   a is: ${a}
---`;
console.log(str);

Output:

---
   a is: 123
---

What is more important, they can contain not just a variable name, but any JavaScript expression:

var a = 3, b = 3.1415;

console.log(`PI is nearly ${Math.max(a, b)}`);

Updated Answer (post-WWDC 2016):

iOS apps will require secure HTTPS connections by the end of 2016. Trying turn ATS off may get your app rejected in the future.

App Transport Security, or ATS, is a feature that Apple introduced in iOS 9. When ATS is enabled, it forces an app to connect to web services over an HTTPS connection rather than non secure HTTP.

However, developers can still switch ATS off and allow their apps to send data over an HTTP connection as mentioned in above answers. At the end of 2016, Apple will make ATS mandatory for all developers who hope to submit their apps to the App Store. link

Here is an example of how to control caching on a per-request basis

$.ajax({
    url: "/YourController",
    cache: false,
    dataType: "html",
    success: function(data) {
        $("#content").html(data);
    }
});

If you create a user using a profile like this:

CREATE PROFILE my_profile LIMIT
       PASSWORD_LIFE_TIME 30;
ALTER USER scott PROFILE my_profile;

then you can change the password lifetime like this:

ALTER PROFILE my_profile LIMIT
  PASSWORD_LIFE_TIME UNLIMITED;

I hope that helps.

For modern browsers, use td:nth-child(2) for the second td, and td:nth-child(3) for the third. Remember that these retrieve the second and third td for every row.

If you need compatibility with IE older than version 9, use sibling combinators or JavaScript as suggested by Tim. Also see my answer to this related question for an explanation and illustration of his method.

"How can I directly (without saving the file on 2nd server) download the file from 1st server to client's machine?"

Just use the Client API and get the InputStream from the response

Client client = ClientBuilder.newClient();
String url = "...";
final InputStream responseStream = client.target(url).request().get(InputStream.class);

There are two flavors to get the InputStream. You can also use

Response response = client.target(url).request().get();
InputStream is = (InputStream)response.getEntity();

Which one is the more efficient? I'm not sure, but the returned InputStreams are different classes, so you may want to look into that if you care to.

From 2nd server I can get a ByteArrayOutputStream to get the file from 1st server, can I pass this stream further to the client using the REST service?

So most of the answers you'll see in the link provided by @GradyGCooper seem to favor the use of StreamingOutput. An example implementation might be something like

final InputStream responseStream = client.target(url).request().get(InputStream.class);
System.out.println(responseStream.getClass());
StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) throws IOException, WebApplicationException {  
        int length;
        byte[] buffer = new byte[1024];
        while((length = responseStream.read(buffer)) != -1) {
            out.write(buffer, 0, length);
        }
        out.flush();
        responseStream.close();
    }   
};
return Response.ok(output).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

But if we look at the source code for StreamingOutputProvider, you'll see in the writeTo, that it simply writes the data from one stream to another. So with our implementation above, we have to write twice.

How can we get only one write? Simple return the InputStream as the Response

final InputStream responseStream = client.target(url).request().get(InputStream.class);
return Response.ok(responseStream).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

If we look at the source code for InputStreamProvider, it simply delegates to ReadWriter.writeTo(in, out), which simply does what we did above in the StreamingOutput implementation

 public static void writeTo(InputStream in, OutputStream out) throws IOException {
    int read;
    final byte[] data = new byte[BUFFER_SIZE];
    while ((read = in.read(data)) != -1) {
        out.write(data, 0, read);
    }
}

Asides:

• Client objects are expensive resources. You may want to reuse the same Client for request. You can extract a WebTarget from the client for each request.

  WebTarget target = client.target(url);
  InputStream is = target.request().get(InputStream.class);
  

  I think the WebTarget can even be shared. I can't find anything in the Jersey 2.x documentation (only because it is a larger document, and I'm too lazy to scan through it right now :-), but in the Jersey 1.x documentation, it says the Client and WebResource (which is equivalent to WebTarget in 2.x) can be shared between threads. So I'm guessing Jersey 2.x would be the same. but you may want to confirm for yourself.

• You don't have to make use of the Client API. A download can be easily achieved with the java.net package APIs. But since you're already using Jersey, it doesn't hurt to use its APIs

• The above is assuming Jersey 2.x. For Jersey 1.x, a simple Google search should get you a bunch of hits for working with the API (or the documentation I linked to above)

UPDATE

I'm such a dufus. While the OP and I are contemplating ways to turn a ByteArrayOutputStream to an InputStream, I missed the simplest solution, which is simply to write a MessageBodyWriter for the ByteArrayOutputStream

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.lang.annotation.Annotation;
import java.lang.reflect.Type;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.MultivaluedMap;
import javax.ws.rs.ext.MessageBodyWriter;
import javax.ws.rs.ext.Provider;

@Provider
public class OutputStreamWriter implements MessageBodyWriter<ByteArrayOutputStream> {

    @Override
    public boolean isWriteable(Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return ByteArrayOutputStream.class == type;
    }

    @Override
    public long getSize(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return -1;
    }

    @Override
    public void writeTo(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType,
            MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream)
            throws IOException, WebApplicationException {
        t.writeTo(entityStream);
    }
}

Then we can simply return the ByteArrayOutputStream in the response

return Response.ok(baos).build();

D'OH!

UPDATE 2

Here are the tests I used (

Resource class

@Path("test")
public class TestResource {

    final String path = "some_150_mb_file";

    @GET
    @Produces(MediaType.APPLICATION_OCTET_STREAM)
    public Response doTest() throws Exception {
        InputStream is = new FileInputStream(path);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int len;
        byte[] buffer = new byte[4096];
        while ((len = is.read(buffer, 0, buffer.length)) != -1) {
            baos.write(buffer, 0, len);
        }
        System.out.println("Server size: " + baos.size());
        return Response.ok(baos).build();
    }
}

Client test

public class Main {
    public static void main(String[] args) throws Exception {
        Client client = ClientBuilder.newClient();
        String url = "http://localhost:8080/api/test";
        Response response = client.target(url).request().get();
        String location = "some_location";
        FileOutputStream out = new FileOutputStream(location);
        InputStream is = (InputStream)response.getEntity();
        int len = 0;
        byte[] buffer = new byte[4096];
        while((len = is.read(buffer)) != -1) {
            out.write(buffer, 0, len);
        }
        out.flush();
        out.close();
        is.close();
    }
}

UPDATE 3

So the final solution for this particular use case was for the OP to simply pass the OutputStream from the StreamingOutput's write method. Seems the third-party API, required a OutputStream as an argument.

StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) {
        thirdPartyApi.downloadFile(.., .., .., out);
    }
}
return Response.ok(output).build();

Not quite sure, but seems the reading/writing within the resource method, using ByteArrayOutputStream`, realized something into memory.

The point of the downloadFile method accepting an OutputStream is so that it can write the result directly to the OutputStream provided. For instance a FileOutputStream, if you wrote it to file, while the download is coming in, it would get directly streamed to the file.

It's not meant for us to keep a reference to the OutputStream, as you were trying to do with the baos, which is where the memory realization comes in.

So with the way that works, we are writing directly to the response stream provided for us. The method write doesn't actually get called until the writeTo method (in the MessageBodyWriter), where the OutputStream is passed to it.

You can get a better picture looking at the MessageBodyWriter I wrote. Basically in the writeTo method, replace the ByteArrayOutputStream with StreamingOutput, then inside the method, call streamingOutput.write(entityStream). You can see the link I provided in the earlier part of the answer, where I link to the StreamingOutputProvider. This is exactly what happens

Yes, since some genius in the Java API creation committee decided that, even though certain classes have size() members or length attributes, they won't implement getSize() or getLength() which JSF and most other standards require, you can't do what you want.

There's a couple ways to do this.

One: add a function to your Bean that returns the length:

In class MyBean:
public int getSomelistLength() { return this.somelist.length; }

In your JSF page:
#{MyBean.somelistLength}

Two: If you're using Facelets (Oh, God, why aren't you using Facelets!), you can add the fn namespace and use the length function

In JSF page:
#{ fn:length(MyBean.somelist) }

Depending on which OS you're using, if you are flexible, then CHOICE can be used to wait on almost any key EXCEPT enter

If you are really referring to what Microsoft insists on calling "Command Prompt" which is simply an MS-DOS emulator, then perhaps TIMEOUT may suit your purpose (timeout /t -1 waits on any key, not just ENTER) and of course CHOICE is available again in recent WIN editions.

And a warning on SET /P - whereas set /p DUMMY=Hit ENTER to continue... will work,

set "dummy="
set /p DUMMY=Hit ENTER to continue...
if defined dummy (echo not just ENTER was pressed) else (echo just ENTER was pressed)

will detect whether just ENTER or something else, ending in ENTER was keyed in.

If you are on Mac, make sure you enable annotation processing (tick the checkbox) at these 2 places.

1.) Intellij IDEA -> Preferences -> Compiler -> Annotation Processors

2.) File -> Other Settings -> Default Settings -> Compiler -> Annotation Processors

And then

3.) Intellij IDEA -> Preferences -> Plugins ->Browse Repositories-> Search for "Lombok"-> install plugin -> Apply and restart IDEA

4.) And then probably restart Intellij IDEA.

This is my IntelliJ IDEA and Mac Version - IntelliJ IDEA 2017.1.5 Build #IU-171.4694.70 --- Mac OS X 10.12

Default argument values are evaluated at function define-time, but self is an argument only available at function call time. Thus arguments in the argument list cannot refer each other.

It's a common pattern to default an argument to None and add a test for that in code:

def p(self, b=None):
    if b is None:
        b = self.a
    print b

Latest browsers provide a cleaner method for extending Object.prototype. This code will make the property hidden from property enumeration (for p in o)

For the browsers that implement defineProperty, you can implement uniqueId property like this:

(function() {
    var id_counter = 1;
    Object.defineProperty(Object.prototype, "__uniqueId", {
        writable: true
    });
    Object.defineProperty(Object.prototype, "uniqueId", {
        get: function() {
            if (this.__uniqueId == undefined)
                this.__uniqueId = id_counter++;
            return this.__uniqueId;
        }
    });
}());

For details, see https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Object/defineProperty

Or Simply you Can add

protected void onPreExecute() {
    mDialog = ProgressDialog.show(mContext, "", "Saving changes...", true, false);
}

which will make the ProgressDialog to not cancel-able

If I properly understood your question, supposing your running script is

/relative/path/to/script/index.php

This would give you the parent directory of your running script relative to the document www:

$parent_dir = dirname(dirname($_SERVER['SCRIPT_NAME'])) . '/';
//$parent_dir will be '/relative/path/to/'

If you want the parent directory of your running script relative to server root:

$parent_dir = dirname(dirname($_SERVER['SCRIPT_FILENAME'])) . '/';
//$parent_dir will be '/root/some/path/relative/path/to/'

May be the browser will do it for you if you do something like:

Copy the div and its attributes and insert it before the old one, then move the content from the old to the new and delete the old?

A lot of good responses here; I especially like the lambda expressions...very clean. I was remiss, however, in not specifying the type of Collection. This is a SPRoleAssignmentCollection (from MOSS) that only has Remove(int) and Remove(SPPrincipal), not the handy RemoveAll(). So, I have settled on this, unless there is a better suggestion.

foreach (SPRoleAssignment spAssignment in workspace.RoleAssignments)
{
    if (spAssignment.Member.Name != shortName) continue;
    workspace.RoleAssignments.Remove((SPPrincipal)spAssignment.Member);
    break;
}

Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:

                   240p       360p        480p        720p        1080p
Resolution      426 x 240   640 x 360   854x480     1280x720    1920x1080
Video Bitrates                   
Maximum         700 Kbps    1000 Kbps   2000 Kbps   4000 Kbps   6000 Kbps
Recommended     400 Kbps    750 Kbps    1000 Kbps   2500 Kbps   4500 Kbps
Minimum         300 Kbps    400 Kbps    500 Kbps    1500 Kbps   3000 Kbps

It would appear as though this is the case, although the numbers dont sync up to the google table above:

// the bitrates, video width and file names for this clip
      bitrates: [
        { url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video
        { url: "bbb-1200.mp4", width: 720, bitrate: 1200 }, //480p video
        { url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
      ],

Try to add auth method explicitly as below, because sometimes it is required:

session.setConfig("PreferredAuthentications", "password");

You should add a .gitignore file to your project and add /.idea to it. You should add each directory / file in one line.

If you have an existing .gitignore file then you should simply add a new line to the file and put /.idea to the new line.

After that run git rm -r --cached .idea command.

If you faced an error you can run git rm -r -f --cached .idea command. After all run git add . and then git commit -m "Removed .idea directory and added a .gitignore file" and finally push the changes by running git push command.

For performance reasons, please do not use recursion. It would be disastrous.

Using the stack is convenient(like recursive call), but it comes at a cost: storing detailed information can take up a lot of memory.

If the stack is high, it means that the computer stores a lot of information about function calls.

The method only takes up constant memory(like iteration).

Or Using for loop

Dim myRow() As Data.DataRow
myRow = dt.Select("MyColumnName = 'SomeColumnTitle'")
myRow(0)("SomeOtherColumnTitle") = strValue

Code above instantiates a DataRow. Where "dt" is a DataTable, you get a row by selecting any column (I know, sounds backwards). Then you can then set the value of whatever row you want (I chose the first row, or "myRow(0)"), for whatever column you want.

If we need only one column to be numeric

yyz$b <- as.numeric(as.character(yyz$b))

But, if all the columns needs to changed to numeric, use lapply to loop over the columns and convert to numeric by first converting it to character class as the columns were factor.

yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))

Both the columns in the OP's post are factor because of the string "n/a". This could be easily avoided while reading the file using na.strings = "n/a" in the read.table/read.csv or if we are using data.frame, we can have character columns with stringsAsFactors=FALSE (the default is stringsAsFactors=TRUE)

Regarding the usage of apply, it converts the dataset to matrix and matrix can hold only a single class. To check the class, we need

lapply(yyz, class)

Or

sapply(yyz, class)

Or check

str(yyz)

it is better to use CONCAT function in PostgreSQL for concatenation

eg : select CONCAT(first_name,last_name) from person where pid = 136

if you are using column_a || ' ' || column_b for concatenation for 2 column , if any of the value in column_a or column_b is null query will return null value. which may not be preferred in all cases.. so instead of this

||

use

CONCAT

it will return relevant value if either of them have value

You're making an HTTP POST, but trying to pass parameters with the GET query string syntax. In a POST, the data are passed as named parameters and do not use the param=value&foo=bar syntax. Using jQuery's ajax method lets you create a javascript object with the named parameters, like so:

$.ajax({
  url: '/Home/SaveChart',
  type: 'POST',
  async: false,
  dataType: 'text',
  processData: false,    
  data: { 
      input: JSON.stringify(IVRInstant.data), 
      name: $("#wrkname").val()
  },
  success: function (data) { }
});

Now I solved this issue in this way,

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import java.io.OutputStream;
// Create a trust manager that does not validate certificate chains like the 
default TrustManager[] trustAllCerts = new TrustManager[] {
    new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
        }
        public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
            //No need to implement. 
        }
        public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
            //No need to implement. 
        }
    }
};
// Install the all-trusting trust manager
try {
    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new java.security.SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
    System.out.println(e);
}

Old post but I made an good solution what is tested on serval places.

https://github.com/CreativForm/Load-jQuery-if-it-is-not-already-loaded

CODE:

(function(url, position, callback){
    // default values
    url = url || 'https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js';
    position = position || 0;

    // Check is jQuery exists
    if (!window.jQuery) {
        // Initialize <head>
        var head = document.getElementsByTagName('head')[0];
        // Create <script> element
        var script = document.createElement("script");
        // Append URL
        script.src = url;
        // Append type
        script.type = 'text/javascript';
        // Append script to <head>
        head.appendChild(script);
        // Move script on proper position
        head.insertBefore(script,head.childNodes[position]);

        script.onload = function(){
            if(typeof callback == 'function') {
                callback(jQuery);
            }
        };
    } else {
        if(typeof callback == 'function') {
            callback(jQuery);
        }
    }
}('https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js', 5, function($){ 
    console.log($);
}));

At GitHub is better explanation but generaly this function you can add anywhere in your HTML code and you will initialize jquery if is not already loaded.

I had this same problem.

Did:

f1 = plt.figure(1)

# code for figure 1

# don't write 'plt.show()' here


f2 = plt.figure(2)

# code for figure 2

plt.show()

Write 'plt.show()' only once, after the last figure. Worked for me.

Can keep global variables in webpack i.e. in webpack.config.js

externals: {
  'config': JSON.stringify(GLOBAL_VARIABLE: "global var value")
}

In js module can read like

var config = require('config')
var GLOBAL_VARIABLE = config.GLOBAL_VARIABLE

Hope this will help.

Raising Matt Dowle's comment to Geneorama's answer (https://stackoverflow.com/a/20808945/4241780) to make it more obvious (as encouraged), you can use for(...)set(...).

library(data.table)

DT = data.table(a = LETTERS[c(3L,1:3)], b = 4:7, c = letters[1:4])
DT1 <- copy(DT)
names_factors <- c("a", "c")

for(col in names_factors)
  set(DT, j = col, value = as.factor(DT[[col]]))

sapply(DT, class)
#>         a         b         c 
#>  "factor" "integer"  "factor"

See another of Matt's comments at https://stackoverflow.com/a/33000778/4241780 for more info.

Edit.

As noted by Espen and in help(set), j may be "Column name(s) (character) or number(s) (integer) to be assigned value when column(s) already exist". So names_factors <- c(1L, 3L) will also work.

For those who Google for this error and arrive here: there might be another reason for receiving it. Eclipse gives this error when you have project setup - system configuration mismatch.

For example, if you import Java 1.7 project to Eclipse and you do not have 1.7 correctly set up then you will get this error. Then you can either go to Project - Preference - Java - Compiler and switch to 1.6 or earlier; or go to Window - Preferences - Java - Installed JREs and add/fix your JRE 1.7 installation.

Meet same Issue on one mac, but ok on another mac. I'm sure bundle ID is fine and unique.

I know it is provisioning profile issue, so Try refreshing the provisioning profile on your Local computer. Then It Works!

1. cd ~/Library/MobileDevice/Provisioning\ Profiles
2. rm *
3. Xcode > Preferences... > Accounts > click your Account and Team name > click Download Manual Profiles
4. Run app again

You need to import not only your secret key, but also the corresponding public key, or you'll get this error.

foreach (string s in sList)
{
    if (s.equals("ok"))
        return true;
}

return false;

Alternatively, if you need to do some other things after you've found the item:

bool found = false;
foreach (string s in sList)
{
    if (s.equals("ok"))
    {
        found = true;
        break; // get out of the loop
    }
}

// do stuff

return found;

C# adaptation of approach often used in C - set value of outer loop's variable outside of loop conditions (i.e. for loop using int variable INT_MAX -1 is often good choice):

for (int i = 0; i < 100; i++)
{
    for (int j = 0; j < 100; j++)
    {
        if (exit_condition)
        {
            // cause the outer loop to break:
            // use i = INT_MAX - 1; otherwise i++ == INT_MIN < 100 and loop will continue 
            i = int.MaxValue - 1;
            Console.WriteLine("Hi");
            // break the inner loop
            break;
        }
    }
    // if you have code in outer loop it will execute after break from inner loop    
}

As note in code says break will not magically jump to next iteration of the outer loop - so if you have code outside of inner loop this approach requires more checks. Consider other solutions in such case.

This approach works with for and while loops but does not work for foreach. In case of foreach you won't have code access to the hidden enumerator so you can't change it (and even if you could IEnumerator doesn't have some "MoveToEnd" method).

This happened to me once after I merged a pull request on Bitbucket.

I just had to do:

git fetch

My problem was solved. I hope this helps!!!

That works:

DateTime dt = DateTime.ParseExact("2011-29-01 12:00 am", "yyyy-dd-MM hh:mm tt", System.Globalization.CultureInfo.InvariantCulture);

Got the solution and it's working fine. Set the environment variables as:

• CATALINA_HOME=C:\Program Files\Java\apache-tomcat-7.0.59\apache-tomcat-7.0.59 (path where your Apache Tomcat is)
• JAVA_HOME=C:\Program Files\Java\jdk1.8.0_25; (path where your JDK is)
• JRE_Home=C:\Program Files\Java\jre1.8.0_25; (path where your JRE is)
• CLASSPATH=%JAVA_HOME%\bin;%JRE_HOME%\bin;%CATALINA_HOME%\lib

For any non-trivial application (I.E. the application must receive and handle different kinds of messages with different lengths), the solution to your particular problem isn't necessarily just a programming solution - it's a convention, I.E. a protocol.

In order to determine how many bytes you should pass to your read call, you should establish a common prefix, or header, that your application receives. That way, when a socket first has reads available, you can make decisions about what to expect.

A binary example might look like this:

#include <stdint.h>
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <arpa/inet.h>

enum MessageType {
    MESSAGE_FOO,
    MESSAGE_BAR,
};

struct MessageHeader {
    uint32_t type;
    uint32_t length;
};

/**
 * Attempts to continue reading a `socket` until `bytes` number
 * of bytes are read. Returns truthy on success, falsy on failure.
 *
 * Similar to @grieve's ReadXBytes.
 */
int readExpected(int socket, void *destination, size_t bytes)
{
    /*
    * Can't increment a void pointer, as incrementing
    * is done by the width of the pointed-to type -
    * and void doesn't have a width
    *
    * You can in GCC but it's not very portable
    */
    char *destinationBytes = destination;
    while (bytes) {
        ssize_t readBytes = read(socket, destinationBytes, bytes);
        if (readBytes < 1)
            return 0;
        destinationBytes += readBytes;
        bytes -= readBytes;
    }
    return 1;
}

int main(int argc, char **argv)
{
    int selectedFd;

    // use `select` or `poll` to wait on sockets
    // received a message on `selectedFd`, start reading

    char *fooMessage;
    struct {
        uint32_t a;
        uint32_t b;
    } barMessage;

    struct MessageHeader received;
    if (!readExpected (selectedFd, &received, sizeof(received))) {
        // handle error
    }
    // handle network/host byte order differences maybe
    received.type = ntohl(received.type);
    received.length = ntohl(received.length);

    switch (received.type) {
        case MESSAGE_FOO:
            // "foo" sends an ASCII string or something
            fooMessage = calloc(received.length + 1, 1);
            if (readExpected (selectedFd, fooMessage, received.length))
                puts(fooMessage);
            free(fooMessage);
            break;
        case MESSAGE_BAR:
            // "bar" sends a message of a fixed size
            if (readExpected (selectedFd, &barMessage, sizeof(barMessage))) {
                barMessage.a = ntohl(barMessage.a);
                barMessage.b = ntohl(barMessage.b);
                printf("a + b = %d\n", barMessage.a + barMessage.b);
            }
            break;
        default:
            puts("Malformed type received");
            // kick the client out probably
    }
}

You can likely already see one disadvantage of using a binary format - for each attribute greater than a char you read, you will have to ensure its byte order is correct using the ntohl or ntohs functions.

An alternative is to use byte-encoded messages, such as simple ASCII or UTF-8 strings, which avoid byte-order issues entirely but require extra effort to parse and validate.

There are two final considerations for network data in C.

The first is that some C types do not have fixed widths. For example, the humble int is defined as the word size of the processor, so 32 bit processors will produce 32 bit ints, while 64 bit processors will produces 64 bit ints. Good, portable code should have network data use fixed-width types, like those defined in stdint.h.

The second is struct padding. A struct with different-widthed members will add data in between some members to maintain memory alignment, making the struct faster to use in the program but sometimes producing confusing results.

#include <stdio.h>
#include <stdint.h>

int main()
{
    struct A {
        char a;
        uint32_t b;
    } A;

    printf("sizeof(A): %ld\n", sizeof(A));
}

In this example, its actual width won't be 1 char + 4 uint32_t = 5 bytes, it'll be 8:

mharrison@mharrison-KATANA:~$ gcc -o padding padding.c
mharrison@mharrison-KATANA:~$ ./padding 
sizeof(A): 8

This is because 3 bytes are added after char a to make sure uint32_t b is memory-aligned.

So if you write a struct A, then attempt to read a char and a uint32_t on the other side, you'll get char a, and a uint32_t where the first three bytes are garbage and the last byte is the first byte of the actual integer you wrote.

Either document your data format explicitly as C struct types or, better yet, document any padding bytes they might contain.

SHIFT+CTRL+B should work

However sometimes an issue can happen in a locked down non-adminstrator evironment:

If you open an existing C# application from the folder you should have a .sln (solution file) etc..

A good library is Shield UI - you can take a look at their flexible Splitter widget and the rest of the powerful components the framework offers.

You can use groupBy of angular.filter module.
so you can do something like this:

JS:

$scope.players = [
  {name: 'Gene', team: 'alpha'},
  {name: 'George', team: 'beta'},
  {name: 'Steve', team: 'gamma'},
  {name: 'Paula', team: 'beta'},
  {name: 'Scruath', team: 'gamma'}
];

HTML:

<ul ng-repeat="(key, value) in players | groupBy: 'team'">
  Group name: {{ key }}
  <li ng-repeat="player in value">
    player: {{ player.name }} 
  </li>
</ul>

RESULT:
Group name: alpha
* player: Gene
Group name: beta
* player: George
* player: Paula
Group name: gamma
* player: Steve
* player: Scruath

UPDATE: jsbin Remember the basic requirements to use angular.filter, specifically note you must add it to your module's dependencies:

(1) You can install angular-filter using 4 different methods:

1. clone & build this repository
2. via Bower: by running $ bower install angular-filter from your terminal
3. via npm: by running $ npm install angular-filter from your terminal
4. via cdnjs http://www.cdnjs.com/libraries/angular-filter

(2) Include angular-filter.js (or angular-filter.min.js) in your index.html, after including Angular itself.

(3) Add 'angular.filter' to your main module's list of dependencies.

You can use this command: ECHO >> filename.txt

it will create a file with the given extension in the current folder.

UPDATE:

for an empty file use: copy NUL filename.txt

PDT eclipse from ZEND has a mac version (PDT all-in-one).

I've been using it for about 3 months and it's pretty solid and has debugging capabilities with xdebug (debug howto) and zend debugger.

I tried an out of the box approach to this, I havent tested this for PDF content but it did work for normal HTML based content, heres how:

Step 1: Wrap your Iframe in a div wrapper

Step 2: Add a background image to your div wrapper:

.wrapperdiv{
  background-image:url(img/loading.gif);
  background-repeat:no-repeat;
  background-position:center center; /*Can place your loader where ever you like */
}

Step 3: in ur iframe tag add ALLOWTRANSPARENCY="false"

The idea is to show the loading animation in the wrapper div till the iframe loads after it has loaded the iframe would cover the loading animation.

Give it a try.

ifeq "$(wildcard $(MY_DIRNAME) )" ""
  -mkdir $(MY_DIRNAME)
endif

You're missing the binding of the method in the constructor. This is how React suggests that you do it:

class Whatever {
  constructor() {
    super();
    this.onKeyPressed = this.onKeyPressed.bind(this);
  }

  onKeyPressed(e) {
    // your code ...
  }

  render() {
    return (<div onKeyDown={this.onKeyPressed} />);
  }
}

There are other ways of doing this, but this will be the most efficient at runtime.

checkout the example here

http://svn.apache.org/repos/asf/poi/trunk/src/examples/src/org/apache/poi/ss/examples/BusinessPlan.java

style.setFillForegroundColor(IndexedColors.LIGHT_CORNFLOWER_BLUE.getIndex());

If the div where you want to put your element has content inside, and you want the element to show after the main content:

  $("#destination").append($("#source"));

If the div where you want to put your element has content inside, and you want to show the element before the main content:

$("#destination").prepend($("#source"));

If the div where you want to put your element is empty, or you want to replace it entirely:

$("#element").html('<div id="source">...</div>');

If you want to duplicate an element before any of the above:

$("#destination").append($("#source").clone());
// etc.

The distinction between TO, CC and BCC occurs only in the text headers. At the SMTP level, everybody is a recipient.

TO - There is a TO: header with this recipient's address

CC - There is a CC: header with this recipient's address

BCC - This recipient isn't mentioned in the headers at all, but is still a recipient.

If you have

TO: [email protected]
CC: [email protected]
BCC: [email protected]

You have three recipients. The headers in the email body will include only the TO: and CC:

All I had to do was add:

in my

I use the command pkill for this:

NAME
       pgrep, pkill - look up or signal processes based on name and 
       other attributes

SYNOPSIS
       pgrep [options] pattern
       pkill [options] pattern

DESCRIPTION
       pgrep looks through the currently running processes and lists 
       the process IDs which match the selection criteria to stdout.
       All the criteria have to match.  For example,

              $ pgrep -u root sshd

       will only list the processes called sshd AND owned by root.
       On the other hand,

              $ pgrep -u root,daemon

       will list the processes owned by root OR daemon.

       pkill will send the specified signal (by default SIGTERM) 
       to each process instead of listing them on stdout.

If your code runs via interpreter (java, python, ...) then the name of the process is the name of the interpreter. You need to user the argument --full. This matches against the command name and the arguments.

Use display: none instead. Besides, this is probably what you need, because this also truncates the page by removing the space the table occupies, whereas visibility: hidden leaves the white space left by the table.

One difference that's not at the language level but the popular implementation level: certain versions of gcc will remove unreferenced static inline functions from output by default, but will keep plain static functions even if unreferenced. I'm not sure which versions this applies to, but from a practical standpoint it means it may be a good idea to always use inline for static functions in headers.

<?php

// do something here

header("Location: http://example.com/thankyou.php");
?>

you may try using trigger() Reference Link

$('#form_id').trigger("reset");

Should you want to add a new column (say 'count_column') containing the groups' counts into the dataframe:

df.count_column=df.groupby(['col5','col2']).col5.transform('count')

(I picked 'col5' as it contains no nan)

Don't know if it's quicker, but, you could save a line of code with your method:

From

$array = array('lastname', 'email', 'phone');
$comma_separated = implode("','", $array);
$comma_separated = "'".$comma_separated."'";

To:

$array = array('lastname', 'email', 'phone');
$comma_separated = "'".implode("','", $array)."'";

in case you are interested in reading some data from a .txt file and only extract few columns of that file into a new .txt file with a customized header, the following code might be useful:

# input some data from 2 different .txt files:
civit_gps <- read.csv(file="/path2/gpsFile.csv",head=TRUE,sep=",")
civit_cam <- read.csv(file="/path2/cameraFile.txt",head=TRUE,sep=",")

# assign the name for the output file:
seqName <- "seq1_data.txt"

#=========================================================
# Extract data from imported files
#=========================================================
# From Camera:
frame_idx <- civit_cam$X.frame
qx        <- civit_cam$q.x.rad.
qy        <- civit_cam$q.y.rad.
qz        <- civit_cam$q.z.rad.
qw        <- civit_cam$q.w

# From GPS:
gpsT      <- civit_gps$X.gpsTime.sec.
latitude  <- civit_gps$Latitude.deg.
longitude <- civit_gps$Longitude.deg.
altitude  <- civit_gps$H.Ell.m.
heading   <- civit_gps$Heading.deg.
pitch     <- civit_gps$pitch.deg.
roll      <- civit_gps$roll.deg.
gpsTime_corr <- civit_gps[frame_idx,1]

#=========================================================
# Export new data into the output txt file
#=========================================================
myData <- data.frame(c(gpsTime_corr),
                     c(frame_idx),
                     c(qx),
                     c(qy),
                     c(qz),
                     c(qw))
# Write :
cat("#GPSTime,frameIdx,qx,qy,qz,qw\n", file=seqName)
write.table(myData, file = seqName,row.names=FALSE,col.names=FALSE,append=TRUE,sep = ",")

Of course, you should modify this sample script based on your own application.

In the default installation, call a page that doesn't exist and you get an error with the version at the end:

In Python 2.6+, you could use io.open() that is default (builtin open()) on Python 3:

import io

with io.open(filename, 'w', encoding=character_encoding) as file:
    file.write(unicode_text)

It might be more convenient if you need to write the text incrementally (you don't need to call unicode_text.encode(character_encoding) multiple times). Unlike codecs module, io module has a proper universal newlines support.

If you dont want to format a separate column with you normal dates pasted to it -- do the following -- add a column to the extreme left of your data and reverve your date ie if the date you had already entered was for example 11.5.16 enter int he new lefthand column 160511 ( notice that there are numbers only and no full stops . When you now sort there will be no mix ups as you have encountered.i have used this method for over 30 years and it never lets me down. And as you have placed the date by year, month and day you neednt include that column if you want or need tu print out your complete list.

Try {{model?.person.name}} this should wait for model to not be undefined and then render.

Angular 2 refers to this ?. syntax as the Elvis operator. Reference to it in the documentation is hard to find so here is a copy of it in case they change/move it:

The Elvis Operator ( ?. ) and null property paths

The Angular “Elvis” operator ( ?. ) is a fluent and convenient way to guard against null and undefined values in property paths. Here it is, protecting against a view render failure if the currentHero is null.

The current hero's name is {{currentHero?.firstName}}

Let’s elaborate on the problem and this particular solution.

What happens when the following data bound title property is null?

The title is {{ title }}

The view still renders but the displayed value is blank; we see only "The title is" with nothing after it. That is reasonable behavior. At least the app doesn't crash.

Suppose the template expression involves a property path as in this next example where we’re displaying the firstName of a null hero.

The null hero's name is {{nullHero.firstName}}

JavaScript throws a null reference error and so does Angular:

TypeError: Cannot read property 'firstName' of null in [null]

Worse, the entire view disappears.

We could claim that this is reasonable behavior if we believed that the hero property must never be null. If it must never be null and yet it is null, we've made a programming error that should be caught and fixed. Throwing an exception is the right thing to do.

On the other hand, null values in the property path may be OK from time to time, especially when we know the data will arrive eventually.

While we wait for data, the view should render without complaint and the null property path should display as blank just as the title property does.

Unfortunately, our app crashes when the currentHero is null.

We could code around that problem with NgIf

<!--No hero, div not displayed, no error --> <div *ngIf="nullHero">The null hero's name is {{nullHero.firstName}}</div>

Or we could try to chain parts of the property path with &&, knowing that the expression bails out when it encounters the first null.

The null hero's name is {{nullHero && nullHero.firstName}}

These approaches have merit but they can be cumbersome, especially if the property path is long. Imagine guarding against a null somewhere in a long property path such as a.b.c.d.

The Angular “Elvis” operator ( ?. ) is a more fluent and convenient way to guard against nulls in property paths. The expression bails out when it hits the first null value. The display is blank but the app keeps rolling and there are no errors.

<!-- No hero, no problem! --> The null hero's name is {{nullHero?.firstName}}

It works perfectly with long property paths too:

a?.b?.c?.d

The easiest and fastest way to convert a Pandas dataframe into a png image using Anaconda Spyder IDE- just double-click on the dataframe in variable explorer, and the IDE table will appear, nicely packaged with automatic formatting and color scheme. Just use a snipping tool to capture the table for use in your reports, saved as a png:

This saves me lots of time, and is still elegant and professional.

Since Java 13 you have formatted 1 method on String, which was added along with text blocks as a preview feature 2. You can use it instead of String.format()

Assertions.assertEquals(
   "%s %d %.3f".formatted("foo", 123, 7.89),
   "foo 123 7.890"
);

There is still another way to do it, which is using a particular NamingStrategy, which can be applied to a class or a property by decorating them with [JSonObject] or [JsonProperty].

There are predefined naming strategies like CamelCaseNamingStrategy, but you can implement your own ones.

The implementation of different naming strategies can be found here: https://github.com/JamesNK/Newtonsoft.Json/tree/master/Src/Newtonsoft.Json/Serialization

If you're OK with littering your markup a bit, you could do it the easy way and just wrap your <button> with an anchor (<a>) link.

<a href="#/new-page.html"><button>New Page<button></a>

Also, there is nothing stopping you from styling an anchor link to look like a <button>

as pointed out in the comments by @tronman, this is not technically valid html5, but it should not cause any problems in practice

Structure in C

First you need to declare your structure:

struct mystruct{
 char element_1,
 char element_2
};

Instantiate C structure

Once you declared your structure , you can instantiate a variable that has as type your structure using either:

mystruct struct_example;

or :

mystruct* struct_example;

For the first use case you can access the varaiable eleemnet using the following syntax: struct_example.element_1 = 5;

For the second use case which is having a pointer to variable of type your structure, to be able to access the variable structure you need an arrow:

struct_example->element_1 = 5;

As of R 3.3.0, one may use startsWith() as a faster alternative to grepl():

which(startsWith(mydata_2$height_seca1, 1578))

Don't disable it; instead set it to readonly, though this has no effect as per not allowing the user to change the state. But you can use jQuery to enforce this (prevent the user from changing the state of the checkbox:

$('input[type="checkbox"][readonly="readonly"]').click(function(e){
    e.preventDefault();
});

This assumes that all the checkboxes you don't want to be modified have the "readonly" attribute. eg.

<input type="checkbox" readonly="readonly">

Jquery like any other good JavaScript frameworks supplies you with functionality independent of browser platform wrapping all the intricacies, which you may not care about or don't want to care about.

I think using a framework is better instead of using pure JavaScript and doing all the stuff from scratch, unless you usage is very limited.

I definitely recommend JQuery!

Thanks

You need to use cv.LoadImageM instead of cv.LoadImage:

In [1]: import cv
In [2]: import numpy as np
In [3]: x = cv.LoadImageM('im.tif')
In [4]: im = np.asarray(x)
In [5]: im.shape
Out[5]: (487, 650, 3)

REST doesn't have a recommended date format. Really it boils down to what works best for your end user and your system. Personally, I would want to stick to a standard like you have for ISO 8601 (url encoded).

If not having ugly URI is a concern (e.g. not including the url encoded version of :, -, in you URI) and (human) addressability is not as important, you could also consider epoch time (e.g. http://example.com/start/1331162374). The URL looks a little cleaner, but you certainly lose readability.

The /2012/03/07 is another format you see a lot. You could expand upon that I suppose. If you go this route, just make sure you're either always in GMT time (and make that clear in your documentation) or you might also want to include some sort of timezone indicator.

Ultimately it boils down to what works for your API and your end user. Your API should work for you, not you for it ;-).

Had the same error while using SourceTree connected to BitBucket repository.

When navigating to repository url on bitbucket.org the warning message appeared:

This repository is in read-only mode. You caught us doing some quick maintenance.

After around 2 hours repository was accessible again.

You can check status and uptime of bitbucket here: http://status.bitbucket.org/

After searching the Web and trying many different ways, here's what I'd suggest for Java EE 6 authentication:

Set up the security realm:

In my case, I had the users in the database. So I followed this blog post to create a JDBC Realm that could authenticate users based on username and MD5-hashed passwords in my database table:

http://blog.gamatam.com/2009/11/jdbc-realm-setup-with-glassfish-v3.html

Note: the post talks about a user and a group table in the database. I had a User class with a UserType enum attribute mapped via javax.persistence annotations to the database. I configured the realm with the same table for users and groups, using the userType column as the group column and it worked fine.

Use form authentication:

Still following the above blog post, configure your web.xml and sun-web.xml, but instead of using BASIC authentication, use FORM (actually, it doesn't matter which one you use, but I ended up using FORM). Use the standard HTML , not the JSF .

Then use BalusC's tip above on lazy initializing the user information from the database. He suggested doing it in a managed bean getting the principal from the faces context. I used, instead, a stateful session bean to store session information for each user, so I injected the session context:

 @Resource
 private SessionContext sessionContext;

With the principal, I can check the username and, using the EJB Entity Manager, get the User information from the database and store in my SessionInformation EJB.

Logout:

I also looked around for the best way to logout. The best one that I've found is using a Servlet:

 @WebServlet(name = "LogoutServlet", urlPatterns = {"/logout"})
 public class LogoutServlet extends HttpServlet {
  @Override
  protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
   HttpSession session = request.getSession(false);

   // Destroys the session for this user.
   if (session != null)
        session.invalidate();

   // Redirects back to the initial page.
   response.sendRedirect(request.getContextPath());
  }
 }

Although my answer is really late considering the date of the question, I hope this helps other people that end up here from Google, just like I did.

Ciao,

I found a solution that works, but it's ugly.

• Connect the Android device to your PC with a USB cable and open Chrome on your desktop.
• Right-click anywhere on a page and select "Inspect".

• Click the three-dot menu and select "Remote devices" under the "More tools" menu:

  

• In the panel that opens, select your device and then the "Inspect" button next to the name of the tab on your phone that needs to be refreshed:

  

• In the window that opens, click the "Network" tab and check the "Disable cache" checkbox:

  

• Reload the page on your phone or using the reload button in the DevTools window.

Note: if your phone doesn't appear in the device list:

• make sure the USB connection is using File Transfer mode and isn't simply charging
• try restarting ADB or run adb devices to see if the device is being detected

You can display flex items inline, providing your assumption is based on wanting flexible inline items in the 1st place. Using flex implies a flexible block level element.

The simplest approach is to use a flex container with its children set to a flex property. In terms of code this looks like this:

.parent{
   display: inline-flex;
}

.children{
   flex: 1;
}

flex: 1 denotes a ratio, similar to percentages of a element's width.

Check these two links in order to see simple live Flexbox examples:

1. https://njbenjamin.com/bundle-3.htm
2. https://njbenjamin.com/bundle-4.htm

If you use the 1st example:

https://njbenjamin.com/flex/index_1.htm

You can play around with your browser console, to change the display of the container element between flex and inline-flex.

Why check at all?

No one seems to have addressed questioning your need to test the list in the first place. Because you provided no additional context, I can imagine that you may not need to do this check in the first place, but are unfamiliar with list processing in Python.

I would argue that the most pythonic way is to not check at all, but rather to just process the list. That way it will do the right thing whether empty or full.

a = []

for item in a:
    <do something with item>

<rest of code>

This has the benefit of handling any contents of a, while not requiring a specific check for emptiness. If a is empty, the dependent block will not execute and the interpreter will fall through to the next line.

If you do actually need to check the array for emptiness, the other answers are sufficient.

You could decorate your view model property with the [DisplayName] attribute and specify the text to be used:

[DisplayName("foo bar")]
public string SomekingStatus { get; set; }

Or use another overload of the LabelFor helper which allows you to specify the text:

@Html.LabelFor(model => model.SomekingStatus, "foo bar")

And, no, you cannot specify a class name in MVC3 as you tried to do, as the LabelFor helper doesn't support that. However, this would work in MVC4 or 5.

Use Css Selector for this, or learn more about Css Selector just go here https://www.w3schools.com/cssref/css_selectors.asp

IEnumerable is an interface that defines one method GetEnumerator which returns an IEnumerator interface, this in turn allows readonly access to a collection. A collection that implements IEnumerable can be used with a foreach statement.

Definition

IEnumerable 

public IEnumerator GetEnumerator();

IEnumerator

public object Current;
public void Reset();
public bool MoveNext();

I would have tagged this as a comment but cant (dont have the rep) just wanted to thank Tilman. I was trying to get PDFsam (PDF Split and Merge) to work to no avail.

At launch it would produce an error stating that it could not find JRE 1.6.0. I Have both 32 and 64 bit versions and they check out fine at the java website in their respective browsers.

Tried uninstalling/reinstalling and rebooting repeatedly as well as using JavaRa. No such luck, still no go.

I looked in the registry after reading this post and there was no ...\SOFTWARE\JavaSoft\ key so I added each with their respective string values pointing to my x86 version (PDFsam is a 32bit program). This got past the first problem but an error popped up about amd64 libraries suggesting the machine wanted to run the 64bit version. So I changed the paths to the 64bit JRE and PDFsam now works.

FYI - I got here by searching for Java registry keys after I was unable to launch javaw.exe from command prompt (even after adding the requisite paths to system path), making the aforementioned changes solved this as well.

I believe the intention is for the script in question to fail fast.

To test this yourself, simply type set -e at a bash prompt. Now, try running ls. You'll get a directory listing. Now, type lsd. That command is not recognized and will return an error code, and so your bash prompt will close (due to set -e).

Now, to understand this in the context of a 'script', use this simple script:

#!/bin/bash 
# set -e

lsd 

ls

If you run it as is, you'll get the directory listing from the ls on the last line. If you uncomment the set -e and run again, you won't see the directory listing as bash stops processing once it encounters the error from lsd.

The "0x" counts towards the eight character count. You need "%#010x".

Note that # does not append the 0x to 0 - the result will be 0000000000 - so you probably actually should just use "0x%08x" anyway.

What you want to do is use the HTML5 attribute placeholder which lets you set a default value for your input box:

<input type="text" name="inputBox" placeholder="enter your text here">

This should achieve what you're looking for. However, be careful because the placeholder attribute is not supported in Internet Explorer 9 and earlier versions.

In Angular 4, you can use environment class to keep all your globals.

You have environment.ts and environment.prod.ts by default.

For example

export const environment = {
  production: false,
  apiUrl: 'http://localhost:8000/api/'
};

And then on your service:

import { environment } from '../../environments/environment';
...
environment.apiUrl;

You can use encoding/binary's ByteOrder to do this for 16, 32, 64 bit types

Play

package main

import "fmt"
import "encoding/binary"

func main() {
    var mySlice = []byte{244, 244, 244, 244, 244, 244, 244, 244}
    data := binary.BigEndian.Uint64(mySlice)
    fmt.Println(data)
}

Why would UPDLOCK block selects? The Lock Compatibility Matrix clearly shows N for the S/U and U/S contention, as in No Conflict.

As for the HOLDLOCK hint the documentation states:

HOLDLOCK: Is equivalent to SERIALIZABLE. For more information, see SERIALIZABLE later in this topic.

...

SERIALIZABLE: ... The scan is performed with the same semantics as a transaction running at the SERIALIZABLE isolation level...

and the Transaction Isolation Level topic explains what SERIALIZABLE means:

No other transactions can modify data that has been read by the current transaction until the current transaction completes.

Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.

Therefore the behavior you see is perfectly explained by the product documentation:

• UPDLOCK does not block concurrent SELECT nor INSERT, but blocks any UPDATE or DELETE of the rows selected by T1
• HOLDLOCK means SERALIZABLE and therefore allows SELECTS, but blocks UPDATE and DELETES of the rows selected by T1, as well as any INSERT in the range selected by T1 (which is the entire table, therefore any insert).
• (UPDLOCK, HOLDLOCK): your experiment does not show what would block in addition to the case above, namely another transaction with UPDLOCK in T2:
  SELECT * FROM dbo.Test WITH (UPDLOCK) WHERE ...
• TABLOCKX no need for explanations

The real question is what are you trying to achieve? Playing with lock hints w/o an absolute complete 110% understanding of the locking semantics is begging for trouble...

After OP edit:

I would like to select rows from a table and prevent the data in that table from being modified while I am processing it.

The you should use one of the higher transaction isolation levels. REPEATABLE READ will prevent the data you read from being modified. SERIALIZABLE will prevent the data you read from being modified and new data from being inserted. Using transaction isolation levels is the right approach, as opposed to using query hints. Kendra Little has a nice poster exlaining the isolation levels.

Just install the m2e plugin for Eclipse. Then a new command in Eclipse's Import statement will be added called "Import existing maven projects".

I'm surprised no one has suggested this yet:

let xs = [1,2,3,4];
for (let i in xs)
    delete xs[i];

This yields an array in quite a different state from the other solutions. In a sense, the array has been 'emptied':

xs
=> Array [ <4 empty slots> ]

[...xs]
=> Array [ undefined, undefined, undefined, undefined ]

xs.length
=> 4

xs[0]
=> ReferenceError: reference to undefined property xs[0]

You can produce an equivalent array with [,,,,] or Array(4)

I usually do something along these lines:

• start with a stem file name (work.dat1 for instance)
• try to create it with CreateNew
• if that works, you've got the file, otherwise...
• mix the current date/time into the filename (work.2011-01-15T112357.dat for instance)
• try to create the file
• if that worked, you've got the file, otherwise...
• Mix a monotonic counter into the filename (work.2011-01-15T112357.0001.dat for instance. (I dislike GUIDs. I prefer order/predictability.)
• try to create the file. Keep ticking up the counter and retrying until a file gets created for you.

Here's a sample class:

static class DirectoryInfoHelpers
{
    public static FileStream CreateFileWithUniqueName( this DirectoryInfo dir , string rootName )
    {
        FileStream fs = dir.TryCreateFile( rootName ) ; // try the simple name first

        // if that didn't work, try mixing in the date/time
        if ( fs == null )
        {
            string date = DateTime.Now.ToString( "yyyy-MM-ddTHHmmss" ) ;
            string stem = Path.GetFileNameWithoutExtension(rootName) ;
            string ext  = Path.GetExtension(rootName) ?? ".dat" ;

            ext = ext.Substring(1);

            string fn = string.Format( "{0}.{1}.{2}" , stem , date , ext ) ;
            fs = dir.TryCreateFile( fn ) ;

            // if mixing in the date/time didn't work, try a sequential search
            if ( fs == null )
            {
                int seq = 0 ;
                do
                {
                    fn = string.Format( "{0}.{1}.{2:0000}.{3}" , stem , date , ++seq , ext ) ;
                    fs = dir.TryCreateFile( fn ) ;
                } while ( fs == null ) ;
            }

        }

        return fs ;
    }

    private static FileStream TryCreateFile(this DirectoryInfo dir , string fileName )
    {
        FileStream fs = null ;
        try
        {
            string fqn = Path.Combine( dir.FullName , fileName ) ;

            fs = new FileStream( fqn , FileMode.CreateNew , FileAccess.ReadWrite , FileShare.None ) ;
        }
        catch ( Exception )
        {
            fs = null ;
        }
        return fs ;
    }

}

You might want to tweak the algorithm (always use all the possible components to the file name for instance). Depends on the context -- If I was creating log files for instance, that I might want to rotate out of existence, you'd want them all to share the same pattern to the name.

The code isn't perfect (no checks on the data passed in for instance). And the algorithm's not perfect (if you fill up the hard drive or encounter permissions, actual I/O errors or other file system errors, for instance, this will hang, as it stands, in an infinite loop).

Put its content in a span which is relatively positioned, then you can control the space by the left property of the span.

li span {_x000D_
  position: relative;_x000D_
  left: -10px;_x000D_
}

<ul>_x000D_
  <li><span>item 1</span></li>_x000D_
  <li><span>item 2</span></li>_x000D_
  <li><span>item 3</span></li>_x000D_
</ul>

According to your query Select * from [User] U where U.DateCreated = '2014-02-07'

SQL Server is comparing exact date and time i.e (comparing 2014-02-07 12:30:47.220 with 2014-02-07 00:00:00.000 for equality). that's why result of comparison is false

Therefore, While comparing dates you need to consider time also. You can use
Select * from [User] U where U.DateCreated BETWEEN '2014-02-07' AND '2014-02-08'.

Change this line

filename1 = datetime.now().strftime("%Y%m%d-%H%M%S")

To

filename1 = datetime.datetime.now().strftime("%Y%m%d-%H%M%S")

Note the extra datetime. Alternatively, change your import datetime to from datetime import datetime

Here is my solution I use for my app.

I have several asset folder with css / js / img anf font files.

The application gets all filenames and looks if a file with this name is requested. If yes, it loads it from asset folder.

//get list of files of specific asset folder
        private ArrayList listAssetFiles(String path) {

            List myArrayList = new ArrayList();
            String [] list;
            try {
                list = getAssets().list(path);
                for(String f1 : list){
                    myArrayList.add(f1);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            return (ArrayList) myArrayList;
        }

        //get mime type by url
        public String getMimeType(String url) {
            String type = null;
            String extension = MimeTypeMap.getFileExtensionFromUrl(url);
            if (extension != null) {
                if (extension.equals("js")) {
                    return "text/javascript";
                }
                else if (extension.equals("woff")) {
                    return "application/font-woff";
                }
                else if (extension.equals("woff2")) {
                    return "application/font-woff2";
                }
                else if (extension.equals("ttf")) {
                    return "application/x-font-ttf";
                }
                else if (extension.equals("eot")) {
                    return "application/vnd.ms-fontobject";
                }
                else if (extension.equals("svg")) {
                    return "image/svg+xml";
                }
                type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
            }
            return type;
        }

        //return webresourceresponse
        public WebResourceResponse loadFilesFromAssetFolder (String folder, String url) {
            List myArrayList = listAssetFiles(folder);
            for (Object str : myArrayList) {

                        Log.i(TAG2, "MIME:" + getMimeType(url));
                        return new WebResourceResponse(getMimeType(url), "UTF-8", getAssets().open(String.valueOf(folder+"/" + str)));
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            }
            return null;
        }

            //Log.i(TAG2, "SHOULD OVERRIDE INIT");
            //String url = webResourceRequest.getUrl().toString();
            String extension = MimeTypeMap.getFileExtensionFromUrl(url);
            //I have some folders for files with the same extension
            if (extension.equals("css") || extension.equals("js") || extension.equals("img")) {
                return loadFilesFromAssetFolder(extension, url);
            }
            //more possible extensions for font folder
            if (extension.equals("woff") || extension.equals("woff2") || extension.equals("ttf") || extension.equals("svg") || extension.equals("eot")) {
                return loadFilesFromAssetFolder("font", url);

        }

git revert -m 1 88113a64a21bf8a51409ee2a1321442fd08db705

But may have unexpected side-effects. See --mainline parent-number option in git-scm.com/docs/git-revert

Perhaps a brute but effective way would be to check out the left parent of that commit, make a copy of all the files, checkout HEAD again, and replace all the contents with the old files. Then git will tell you what is being rolled back and you create your own revert commit :) !

Use the 'right' attribute alongside fixed position styling. The value provided acts as an offset from the right of the window boundary.

Code example:

.test {
  position: fixed;
  right: 0;
}

If you need some padding you can set right property with a certain value, for example: right: 10px.

Note: float property doesn't work for position fixed and absolute

Use eval:

x="ls | wc"
eval "$x"
y=$(eval "$x")
echo "$y"

This will work.

@Test(priority=1)
public void Test1() {

}

@Test(priority=2)
public void Test2() {

}

@Test(priority=3)
public void Test3() {

}

priority encourages execution order but does not guarantee the previous priority level has completed. test3 could start before test2 completes. If a guarantee is needed, then declare a dependency.

Unlike the solutions which declare dependencies, tests which use priority will execute even if one test fails. This problem with dependencies can be worked around with @Test(...alwaysRun = true...) according to documentation.

//do the edit in your javascript

$('.signinform').submit(function() { 
   $(this).ajaxSubmit({ 
       type : "POST",
       //set the data type
       dataType:'json',
       url: 'index.php/user/signin', // target element(s) to be updated with server response 
       cache : false,
       //check this in Firefox browser
       success : function(response){ console.log(response); alert(response)},
       error: onFailRegistered
   });        
   return false; 
}); 


//controller function

public function signin() {
    $arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);    

   //add the header here
    header('Content-Type: application/json');
    echo json_encode( $arr );
}

The following works as of now (tested in chrome and firefox):

<form onsubmit="event.preventDefault(); return validateMyForm();">

where validateMyForm() is a function that returns false if validation fails. The key point is to use the name event. We cannot use for e.g. e.preventDefault()

I tried this code to accept files using Ajax and on submit file gets store using my php file. Code modified slightly to work. (Uploaded Files: PDF,JPG)

function verify1() {
    jQuery.ajax({
        type: 'POST',
        url:"functions.php",
        data: new FormData($("#infoForm1")[0]),
        processData: false, 
        contentType: false, 
        success: function(returnval) {
             $("#show1").html(returnval);
             $('#show1').show();
         }
    });
}

Just print the file details and check. You will get Output. If error let me know.

Your question is a little unclear, but if what you're doing is trying to get your friend's latest changes, then typically what your friend needs to do is to push those changes up to a remote repo (like one hosted on GitHub), and then you fetch or pull those changes from the remote:

1. Your friend pushes his changes to GitHub:

   git push origin <branch>
   

2. Clone the remote repository if you haven't already:

   git clone https://[email protected]/abc/theproject.git
   

3. Fetch or pull your friend's changes (unnecessary if you just cloned in step #2 above):

   git fetch origin
   git merge origin/<branch>
   

   Note that git pull is the same as doing the two steps above:

   git pull origin <branch>

If you are running Tomcat from Eclipse, it doesn't use the configuration from your actual Tomcat installation. It uses the Tomcat configuration that it created and stored under "Servers" project. If you view your Eclipse workspace, you should see a project called "Servers". Expand that "Servers" project and you will come across server.xml. Open this file and scroll all the way to the bottom, and you should see something like this:-

<Context docBase="abc" path="/abc" reloadable="true" source="org.eclipse.jst.jee.server:abc"/>

Here, you can just change your project context path to something else.

Hope this helps.

I just had this problem and I first switched to another directory and then switched back and the problem was fixed.

I think that is what you want, but i don't have access to oracle to test it right now.

Microsoft Support says "Maximum URL length is 2,083 characters in Internet Explorer".

IE has problems with URLs longer than that. Firefox seems to work fine with >4k chars.

How large is length? You may do better to re-use a fixed sized (moderately large, but not obscene) buffer, and forget BinaryReader... just use Stream.Read and Stream.Write.

(edit) something like:

private static void copy(string srcFile, string dstFile, int offset,
     int length, byte[] buffer)
{
    using(Stream inStream = File.OpenRead(srcFile))
    using (Stream outStream = File.OpenWrite(dstFile))
    {
        inStream.Seek(offset, SeekOrigin.Begin);
        int bufferLength = buffer.Length, bytesRead;
        while (length > bufferLength &&
            (bytesRead = inStream.Read(buffer, 0, bufferLength)) > 0)
        {
            outStream.Write(buffer, 0, bytesRead);
            length -= bytesRead;
        }
        while (length > 0 &&
            (bytesRead = inStream.Read(buffer, 0, length)) > 0)
        {
            outStream.Write(buffer, 0, bytesRead);
            length -= bytesRead;
        }
    }        
}

This has already been answered perfectly, but since I just came to this page and did not understand immediately I am just going to add a simple but complete example.

def some_func(a_char, a_float, a_something):
    print a_char

params = ['a', 3.4, None]

Yes, the problem is that there are no commits in "bare". This is a problem with the first commit only, if you create the repos in the order (bare,alice). Try doing:

git push --set-upstream origin master

This would only be required the first time. Afterwards it should work normally.

As Chris Johnsen pointed out, you would not have this problem if your push.default was customized. I like upstream/tracking.

If you want to try it without the try catch block, can use the following method, Create a intent and set the package of the app which you want to verify

val intent = Intent(Intent.ACTION_VIEW)
intent.data = uri
intent.setPackage("com.example.packageofapp")

and the call the following method to check if the app is installed

fun isInstalled(intent:Intent) :Boolean{
    val list = context.packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY)
    return list.isNotEmpty()
}

Try this:

myscript """test"""

"" escape to a single " in the parameter.

You're the victim of the classic deadlock. task.Wait() or task.Result is a blocking call in UI thread which causes the deadlock.

Don't block in the UI thread. Never do it. Just await it.

private async void Button_Click(object sender, RoutedEventArgs 
{
      var task = GetResponseAsync<MyObject>("my url");
      var items = await task;
}

Btw, why are you catching the WebException and throwing it back? It would be better if you simply don't catch it. Both are same.

Also I can see you're mixing the asynchronous code with synchronous code inside the GetResponse method. StreamReader.ReadToEnd is a blocking call --you should be using StreamReader.ReadToEndAsync.

Also use "Async" suffix to methods which returns a Task or asynchronous to follow the TAP("Task based Asynchronous Pattern") convention as Jon says.

Your method should look something like the following when you've addressed all the above concerns.

public static async Task<List<T>> GetResponseAsync<T>(string url)
{
    HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
    var response = (HttpWebResponse)await Task.Factory.FromAsync<WebResponse>(request.BeginGetResponse, request.EndGetResponse, null);

    Stream stream = response.GetResponseStream();
    StreamReader strReader = new StreamReader(stream);
    string text = await strReader.ReadToEndAsync();

    return JsonConvert.DeserializeObject<List<T>>(text);
}

If you want to copy the entire contents of a folder recursively into another folder, you can execute the following windows command from gulp:

xcopy /path/to/srcfolder /path/to/destfolder /s /e /y

The /y option at the end is to suppress the overwrite confirmation message.

In Linux, you can execute the following command from gulp:

cp -R /path/to/srcfolder /path/to/destfolder

you can use gulp-exec or gulp-run plugin to execute system commands from gulp.

Very strange that the very convenient

M-x eval-buffer

is not mentioned here.

It immediately evaluates all code in the buffer, its the quickest method, if your .emacs is idempotent.

You can also use the latest keyword to install the most recent version available:

  "dependencies": {
    "fontawesome": "latest"
  }

As of iOS 9.0 there's no way to get the orientation reliably. This is the code I used for an app I design for only portrait mode, so if the app is opened in landscape mode it will still be accurate:

screenHeight = [[UIScreen mainScreen] bounds].size.height;
screenWidth = [[UIScreen mainScreen] bounds].size.width;
if (screenWidth > screenHeight) {
    float tempHeight = screenWidth;
    screenWidth = screenHeight;
    screenHeight = tempHeight;
}

Since the Date class only has days, you can just do basic arithmetic on it.

If you want to use POSIXlt for some reason, then you can use it's slots:

The Java tutorial says:

Terminology: Nested classes are divided into two categories: static and non-static. Nested classes that are declared static are simply called static nested classes. Non-static nested classes are called inner classes.

In common parlance, the terms "nested" and "inner" are used interchangeably by most programmers, but I'll use the correct term "nested class" which covers both inner and static.

Classes can be nested ad infinitum, e.g. class A can contain class B which contains class C which contains class D, etc. However, more than one level of class nesting is rare, as it is generally bad design.

There are three reasons you might create a nested class:

• organization: sometimes it seems most sensible to sort a class into the namespace of another class, especially when it won't be used in any other context
• access: nested classes have special access to the variables/fields of their containing classes (precisely which variables/fields depends on the kind of nested class, whether inner or static).
• convenience: having to create a new file for every new type is bothersome, again, especially when the type will only be used in one context

There are four kinds of nested class in Java. In brief, they are:

• static class: declared as a static member of another class
• inner class: declared as an instance member of another class
• local inner class: declared inside an instance method of another class
• anonymous inner class: like a local inner class, but written as an expression which returns a one-off object

Let me elaborate in more details.

Static Classes

Static classes are the easiest kind to understand because they have nothing to do with instances of the containing class.

A static class is a class declared as a static member of another class. Just like other static members, such a class is really just a hanger on that uses the containing class as its namespace, e.g. the class Goat declared as a static member of class Rhino in the package pizza is known by the name pizza.Rhino.Goat.

package pizza;

public class Rhino {

    ...

    public static class Goat {
        ...
    }
}

Frankly, static classes are a pretty worthless feature because classes are already divided into namespaces by packages. The only real conceivable reason to create a static class is that such a class has access to its containing class's private static members, but I find this to be a pretty lame justification for the static class feature to exist.

Inner Classes

An inner class is a class declared as a non-static member of another class:

package pizza;

public class Rhino {

    public class Goat {
        ...
    }

    private void jerry() {
        Goat g = new Goat();
    }
}

Like with a static class, the inner class is known as qualified by its containing class name, pizza.Rhino.Goat, but inside the containing class, it can be known by its simple name. However, every instance of an inner class is tied to a particular instance of its containing class: above, the Goat created in jerry, is implicitly tied to the Rhino instance this in jerry. Otherwise, we make the associated Rhino instance explicit when we instantiate Goat:

Rhino rhino = new Rhino();
Rhino.Goat goat = rhino.new Goat();

(Notice you refer to the inner type as just Goat in the weird new syntax: Java infers the containing type from the rhino part. And, yes new rhino.Goat() would have made more sense to me too.)

So what does this gain us? Well, the inner class instance has access to the instance members of the containing class instance. These enclosing instance members are referred to inside the inner class via just their simple names, not via this (this in the inner class refers to the inner class instance, not the associated containing class instance):

public class Rhino {

    private String barry;

    public class Goat {
        public void colin() {
            System.out.println(barry);
        }
    }
}

In the inner class, you can refer to this of the containing class as Rhino.this, and you can use this to refer to its members, e.g. Rhino.this.barry.

Local Inner Classes

A local inner class is a class declared in the body of a method. Such a class is only known within its containing method, so it can only be instantiated and have its members accessed within its containing method. The gain is that a local inner class instance is tied to and can access the final local variables of its containing method. When the instance uses a final local of its containing method, the variable retains the value it held at the time of the instance's creation, even if the variable has gone out of scope (this is effectively Java's crude, limited version of closures).

Because a local inner class is neither the member of a class or package, it is not declared with an access level. (Be clear, however, that its own members have access levels like in a normal class.)

If a local inner class is declared in an instance method, an instantiation of the inner class is tied to the instance held by the containing method's this at the time of the instance's creation, and so the containing class's instance members are accessible like in an instance inner class. A local inner class is instantiated simply via its name, e.g. local inner class Cat is instantiated as new Cat(), not new this.Cat() as you might expect.

Anonymous Inner Classes

An anonymous inner class is a syntactically convenient way of writing a local inner class. Most commonly, a local inner class is instantiated at most just once each time its containing method is run. It would be nice, then, if we could combine the local inner class definition and its single instantiation into one convenient syntax form, and it would also be nice if we didn't have to think up a name for the class (the fewer unhelpful names your code contains, the better). An anonymous inner class allows both these things:

new *ParentClassName*(*constructorArgs*) {*members*}

This is an expression returning a new instance of an unnamed class which extends ParentClassName. You cannot supply your own constructor; rather, one is implicitly supplied which simply calls the super constructor, so the arguments supplied must fit the super constructor. (If the parent contains multiple constructors, the “simplest” one is called, “simplest” as determined by a rather complex set of rules not worth bothering to learn in detail--just pay attention to what NetBeans or Eclipse tell you.)

Alternatively, you can specify an interface to implement:

new *InterfaceName*() {*members*}

Such a declaration creates a new instance of an unnamed class which extends Object and implements InterfaceName. Again, you cannot supply your own constructor; in this case, Java implicitly supplies a no-arg, do-nothing constructor (so there will never be constructor arguments in this case).

Even though you can't give an anonymous inner class a constructor, you can still do any setup you want using an initializer block (a {} block placed outside any method).

Be clear that an anonymous inner class is simply a less flexible way of creating a local inner class with one instance. If you want a local inner class which implements multiple interfaces or which implements interfaces while extending some class other than Object or which specifies its own constructor, you're stuck creating a regular named local inner class.

Just write

declare var $:any;

after all import sections, you can use jQuery and include the jQuery library in your index.html page

<script src="https://code.jquery.com/jquery-3.3.1.js"></script>

it worked for me

Another method is to use HTML5's Application Cache to download all files once and keep them in the browser's cache. The above link contains much more information. The following information is from the article:

Change your <html> tag to include a manifest attribute:

<html manifest="http://www.example.com/example.mf">

A manifest file must be served with the mime-type text/cache-manifest.

A simple manifest looks something like this:

CACHE MANIFEST
index.html
stylesheet.css
images/logo.png
scripts/main.js
http://cdn.example.com/scripts/main.js

Once an application is offline it remains cached until one of the following happens:

1. The user clears their browser's data storage for your site.
2. The manifest file is modified. Note: updating a file listed in the manifest doesn't mean the browser will re-cache that resource. The manifest file itself must be altered.

Paste this code in any of your source files and re-build. Worked for me !

#include stdio.h

FILE _iob[3];

FILE* __cdecl __iob_func(void) {

_iob[0] = *stdin;

_iob[0] = *stdout;

_iob[0] = *stderr;

return _iob;

}

I used JMock early. I've tried Mockito at my last project and liked it. More concise, more cleaner. PowerMock covers all needs which are absent in Mockito, such as mocking a static code, mocking an instance creation, mocking final classes and methods. So I have all I need to perform my work.

Firstly, understand that DateTime objects aren't formatted. They just store the Year, Month, Day, Hour, Minute, Second, etc as a numeric value and the formatting occurs when you want to represent it as a string somehow. You can compare DateTime objects without formatting them.

To compare an input date with DateTime.Now, you need to first parse the input into a date and then compare just the Year/Month/Day portions:

DateTime inputDate;
if(!DateTime.TryParse(inputString, out inputDate))
    throw new ArgumentException("Input string not in the correct format.");

if(inputDate.Date == DateTime.Now.Date) {
    // Same date!
}

That's right, if you're on a mac(unix) you won't see .git in finder(the file browser). You can follow the directions above to delete and there are git commands that allow you to delete files as well(they are sometimes difficult to work with and learn, for example: on making a 'git rm -r ' command you might be prompted with a .git/ not found. Here is the git command specs:

usage: git rm [options] [--] ...

-n, --dry-run         dry run
-q, --quiet           do not list removed files
--cached              only remove from the index
-f, --force           override the up-to-date check
-r                    allow recursive removal
--ignore-unmatch      exit with a zero status even if nothing matched

When I had to do this, deleting the objects and refs didn't matter. After I deleted the other files in the .git, I initialized a git repo with 'git init' and it created an empty repo.

There are two solutions posted on that page. The one with lower votes I would recommend if possible.

If you are using HTML5 then it is perfectly valid to put a div inside of a. As long as the div doesn't also contain some other specific elements like other link tags.

<a href="Music.html">
  <div id="music" class="nav">
    Music I Like
  </div>
</a>

The solution you are confused about actually makes the link as big as its container div. To make it work in your example you just need to add position: relative to your div. You also have a small syntax error which is that you have given the span a class instead of an id. You also need to put your span inside the link because that is what the user is clicking on. I don't think you need the z-index at all from that example.

div { position: relative; }
.hyperspan {
    position:absolute;
    width:100%;
    height:100%;
    left:0;
    top:0;
}

<div id="music" class="nav">Music I Like 
    <a href="http://www.google.com"> 
        <span class="hyperspan"></span>
    </a>   
</div>

http://jsfiddle.net/rBKXM/9

When you give absolute positioning to an element it bases its location and size after the first parent it finds that is relatively positioned. If none, then it uses the document. By adding relative to the parent div you tell the span to only be as big as that.

This is what I do which seems to work quite well:

Date.prototype.addMinutes = function(minutes) {
    var copiedDate = new Date(this.getTime());
    return new Date(copiedDate.getTime() + minutes * 60000);
}

Then you can just call this like this:

var now = new Date();
console.log(now.addMinutes(50));

You could probably use while loop instead of foreach:

while ($current = current($array) )
{
    $next = next($array);
    if (false !== $next && $next == $current)
    {
        //do something with $current
    }
}

In my case you should put the function in $(document).ready

$(document).ready(function () {
    $('div#page').on('scroll', function () {
     ...
    });
});

I have just come across this from Common Crawl.

Might be the answer we are all looking for!!

The !== opererator tests whether values are not equal or not the same type. i.e.

var x = 5;
var y = '5';
var 1 = y !== x; // true
var 2 = y != x; // false

It's true that some databases recognize the OUTER keyword. Some do not. Where it is recognized, it is usually an optional keyword. Almost always, FULL JOIN and FULL OUTER JOIN do exactly the same thing. (I can't think of an example where they do not. Can anyone else think of one?)

This may leave you wondering, "Why would it even be a keyword if it has no meaning?" The answer boils down to programming style.

In the old days, programmers strived to make their code as compact as possible. Every character meant longer processing time. We used 1, 2, and 3 letter variables. We used 2 digit years. We eliminated all unnecessary white space. Some people still program that way. It's not about processing time anymore. It's more about fast coding.

Modern programmers are learning to use more descriptive variables and put more remarks and documentation into their code. Using extra words like OUTER make sure that other people who read the code will have an easier time understanding it. There will be less ambiguity. This style is much more readable and kinder to the people in the future who will have to maintain that code.

A trait is essentially PHP's implementation of a mixin, and is effectively a set of extension methods which can be added to any class through the addition of the trait. The methods then become part of that class' implementation, but without using inheritance.

From the PHP Manual (emphasis mine):

Traits are a mechanism for code reuse in single inheritance languages such as PHP. ... It is an addition to traditional inheritance and enables horizontal composition of behavior; that is, the application of class members without requiring inheritance.

An example:

trait myTrait {
    function foo() { return "Foo!"; }
    function bar() { return "Bar!"; }
}

With the above trait defined, I can now do the following:

class MyClass extends SomeBaseClass {
    use myTrait; // Inclusion of the trait myTrait
}

At this point, when I create an instance of class MyClass, it has two methods, called foo() and bar() - which come from myTrait. And - notice that the trait-defined methods already have a method body - which an Interface-defined method can't.

Additionally - PHP, like many other languages, uses a single inheritance model - meaning that a class can derive from multiple interfaces, but not multiple classes. However, a PHP class can have multiple trait inclusions - which allows the programmer to include reusable pieces - as they might if including multiple base classes.

A few things to note:

                      -----------------------------------------------
                      |   Interface   |  Base Class   |    Trait    |
                      ===============================================
> 1 per class         |      Yes      |       No      |     Yes     |
---------------------------------------------------------------------
Define Method Body    |      No       |       Yes     |     Yes     |
---------------------------------------------------------------------
Polymorphism          |      Yes      |       Yes     |     No      |
---------------------------------------------------------------------

Polymorphism:

In the earlier example, where MyClass extends SomeBaseClass, MyClass is an instance of SomeBaseClass. In other words, an array such as SomeBaseClass[] bases can contain instances of MyClass. Similarly, if MyClass extended IBaseInterface, an array of IBaseInterface[] bases could contain instances of MyClass. There is no such polymorphic construct available with a trait - because a trait is essentially just code which is copied for the programmer's convenience into each class which uses it.

Precedence:

As described in the Manual:

An inherited member from a base class is overridden by a member inserted by a Trait. The precedence order is that members from the current class override Trait methods, which in return override inherited methods.

So - consider the following scenario:

class BaseClass {
    function SomeMethod() { /* Do stuff here */ }
}

interface IBase {
    function SomeMethod();
}

trait myTrait {
    function SomeMethod() { /* Do different stuff here */ }
}

class MyClass extends BaseClass implements IBase {
    use myTrait;

    function SomeMethod() { /* Do a third thing */ }
}

When creating an instance of MyClass, above, the following occurs:

1. The Interface IBase requires a parameterless function called SomeMethod() to be provided.
2. The base class BaseClass provides an implementation of this method - satisfying the need.
3. The trait myTrait provides a parameterless function called SomeMethod() as well, which takes precedence over the BaseClass-version
4. The class MyClass provides its own version of SomeMethod() - which takes precedence over the trait-version.

Conclusion

1. An Interface can not provide a default implementation of a method body, while a trait can.
2. An Interface is a polymorphic, inherited construct - while a trait is not.
3. Multiple Interfaces can be used in the same class, and so can multiple traits.

Use this. It's simple.

Public Function IsDirectoryEmpty(ByVal strDirectoryPath As String) As Boolean
        Dim s() As String = _
            Directory.GetFiles(strDirectoryPath)
        If s.Length = 0 Then
            Return True
        Else
            Return False
        End If
    End Function

Here is a query, you can run it in SQL Developer (or SQL*Plus):

SELECT DS.TABLESPACE_NAME, SEGMENT_NAME, ROUND(SUM(DS.BYTES) / (1024 * 1024)) AS MB
  FROM DBA_SEGMENTS DS
  WHERE SEGMENT_NAME IN (SELECT TABLE_NAME FROM DBA_TABLES)
 GROUP BY DS.TABLESPACE_NAME,
       SEGMENT_NAME;

The correct form, based on the original syntax, and correctly normalized is:

def gaussian(x, mu, sig):
    return 1./(np.sqrt(2.*np.pi)*sig)*np.exp(-np.power((x - mu)/sig, 2.)/2)

You can't insert the values into timestamp column explicitly. It is auto-generated. Do not use this column in your insert statement. Refer http://msdn.microsoft.com/en-us/library/ms182776(SQL.90).aspx for more details.

You could use a datetime instead of a timestamp like this:

create table demo (
    ts datetime
)

insert into demo select current_timestamp

select ts from demo

Returns:

2014-04-04 09:20:01.153

Integer division $x divided by $y ...

$z = -1 & $x / $y

How does it work?

$x / $y

return the floating point division

&

perform a bit-wise AND

-1

stands for

&HFFFFFFFF

for the largest integer ... whence

$z = -1 & $x / $y

gives the integer division ...

Just in case someone stumbles here, I did it this way

  componentDidMount(){
    const node = this.refs.trackerRef;
    node && node.scrollIntoView({block: "end", behavior: 'smooth'})
  }
  componentDidUpdate() {
    const node = this.refs.trackerRef;
    node && node.scrollIntoView({block: "end", behavior: 'smooth'})
  }

  render() {
    return (

      <div>
        {messages.map((msg, index) => {
          return (
            <Message key={index} msgObj={msg}
              {/*<p>some test text</p>*/}
            </Message>
          )
        })}

        <div style={{height: '30px'}} id='#tracker' ref="trackerRef"></div>
      </div>
    )
  }

scrollIntoView is native DOM feature link

It will always shows tracker div
