You can only use absolute path http://grand-shopping.com/<"some folder"> is not an absolute path.

Either you can use a path inside the application which is vurneable or you can use server specific path like in

windows -> C:/Users/puneet verma/Downloads/
linux -> /opt/Downloads/

Its based on from which file you are trying to access those files.

If it is in the same folder where your working project file is, then you can use just the file name. no need of path.

If it is in the another folder which is under the same parent folder of your working project file then you can use location like in the following /javascript/sample.js

In your example if you are trying to access your js file from your html file you can use the following location

../javascript/sample.js

the prefix../ will go to the parent folder of the file(Folder upward journey)

Tomcat-7 JNDI configuration:

Steps:

1. Open the server.xml in the tomcat-dir/conf
2. Add below <Resource> tag with your DB details inside <GlobalNamingResources>

<Resource name="jdbc/mydb"
          global="jdbc/mydb"
          auth="Container"
          type="javax.sql.DataSource"
          driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:3306/test"
          username="root"
          password=""
          maxActive="10"
          maxIdle="10"
          minIdle="5"
          maxWait="10000"/>

3. Save the server.xml file
4. Open the context.xml in the tomcat-dir/conf
5. Add the below <ResourceLink> inside the <Context> tag.

<ResourceLink name="jdbc/mydb" 
              global="jdbc/mydb"
              auth="Container"
              type="javax.sql.DataSource" />

6. Save the context.xml
7. Open the hibernate-cfg.xml file and add and remove below properties.

Adding:
-------
<property name="connection.datasource">java:comp/env/jdbc/mydb</property>

Removing:
--------
<!--<property name="connection.url">jdbc:mysql://localhost:3306/mydb</property> -->
<!--<property name="connection.username">root</property> -->
<!--<property name="connection.password"></property> -->

8. Save the file and put latest .WAR file in tomcat.
9. Restart the tomcat. the DB connection will work.

It's because you're calling doGet() without actually implementing doGet(). It's the default implementation of doGet() that throws the error saying the method is not supported.

A common misunderstanding among starters is that they think that the call of a forward(), sendRedirect(), or sendError() would magically exit and "jump" out of the method block, hereby ignoring the remnant of the code. For example:

protected void doXxx() {
    if (someCondition) {
        sendRedirect();
    }
    forward(); // This is STILL invoked when someCondition is true!
}

This is thus actually not true. They do certainly not behave differently than any other Java methods (expect of System#exit() of course). When the someCondition in above example is true and you're thus calling forward() after sendRedirect() or sendError() on the same request/response, then the chance is big that you will get the exception:

java.lang.IllegalStateException: Cannot forward after response has been committed

If the if statement calls a forward() and you're afterwards calling sendRedirect() or sendError(), then below exception will be thrown:

java.lang.IllegalStateException: Cannot call sendRedirect() after the response has been committed

To fix this, you need either to add a return; statement afterwards

protected void doXxx() {
    if (someCondition) {
        sendRedirect();
        return;
    }
    forward();
}

... or to introduce an else block.

protected void doXxx() {
    if (someCondition) {
        sendRedirect();
    } else {
        forward();
    }
}

To naildown the root cause in your code, just search for any line which calls a forward(), sendRedirect() or sendError() without exiting the method block or skipping the remnant of the code. This can be inside the same servlet before the particular code line, but also in any servlet or filter which was been called before the particular servlet.

In case of sendError(), if your sole purpose is to set the response status, use setStatus() instead.

Another probable cause is that the servlet writes to the response while a forward() will be called, or has been called in the very same method.

protected void doXxx() {
    out.write("some string");
    // ... 
    forward(); // Fail!
}

The response buffer size defaults in most server to 2KB, so if you write more than 2KB to it, then it will be committed and forward() will fail the same way:

java.lang.IllegalStateException: Cannot forward after response has been committed

Solution is obvious, just don't write to the response in the servlet. That's the responsibility of the JSP. You just set a request attribute like so request.setAttribute("data", "some string") and then print it in JSP like so ${data}. See also our Servlets wiki page to learn how to use Servlets the right way.

Another probable cause is that the servlet writes a file download to the response after which e.g. a forward() is called.

protected void doXxx() {
    out.write(bytes);
    // ... 
    forward(); // Fail!
}

This is technically not possible. You need to remove the forward() call. The enduser will stay on the currently opened page. If you actually intend to change the page after a file download, then you need to move the file download logic to page load of the target page.

Yet another probable cause is that the forward(), sendRedirect() or sendError() methods are invoked via Java code embedded in a JSP file in form of old fashioned way <% scriptlets %>, a practice which was officially discouraged since 2001. For example:

<!DOCTYPE html>
<html lang="en">
    <head>
        ... 
    </head>
    <body>
        ...

        <% sendRedirect(); %>
        
        ...
    </body>
</html>

The problem here is that JSP internally immediately writes template text (i.e. HTML code) via out.write("<!DOCTYPE html> ... etc ...") as soon as it's encountered. This is thus essentially the same problem as explained in previous section.

Solution is obvious, just don't write Java code in a JSP file. That's the responsibility of a normal Java class such as a Servlet or a Filter. See also our Servlets wiki page to learn how to use Servlets the right way.

Unrelated to your concrete problem, your JDBC code is leaking resources. Fix that as well. For hints, see also How often should Connection, Statement and ResultSet be closed in JDBC?

        V = V.replace(/,/g,'');

    {
        var V = document.getElementById(arguments[0]).value;
        var R = new RegExp('(-?[0-9]+)([0-9]{3})'); 
        while(R.test(V))
        {
            V = V.replace(R, '$1,$2');
        }
        document.getElementById(arguments[1]).innerHTML = V;
    }
    else return false;
}   

The problem in your code is that you can't store the memory address of a local variable (local to a function, for example) in a globlar variable:

RectInvoice rect(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(&rect);

There, &rect is a temporary address (stored in the function's activation registry) and will be destroyed when that function end.

The code should create a dynamic variable:

RectInvoice *rect =  new RectInvoice(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(rect);

There you are using a heap address that will not be destroyed in the end of the function's execution. Tell me if it worked for you.

Just use

File.Copy(filepath, "\\\\192.168.1.28\\Files");

A windows fileshare exposed via a UNC path is treated as part of the file system, and has nothing to do with the web.

The credentials used will be that of the ASP.NET worker process, or any impersonation you've enabled. If you can tweak those to get it right, this can be done.

You may run into problems because you are using the IP address instead of the server name (windows trust settings prevent leaving the domain - by using IP you are hiding any domain details). If at all possible, use the server name!

If this is not on the same windows domain, and you are trying to use a different domain account, you will need to specify the username as "[domain_or_machine]\[username]"

If you need to specify explicit credentials, you'll need to look into coding an impersonation solution.

In my case, I was using https redirection just before adding cors middleware and able to fix the issue by changing order of them

What i mean is:

change this:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {

      ...
        
        app.UseHttpsRedirection();  

        app.UseCors(x => x
            .AllowAnyOrigin()
            .AllowAnyMethod()
            .AllowAnyHeader());

      ...

     }

to this:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {

      ...
        
        app.UseCors(x => x
            .AllowAnyOrigin()
            .AllowAnyMethod()
            .AllowAnyHeader());

        app.UseHttpsRedirection(); 

      ...

     }

By the way, allowing requests from any origins and methods may not be a good idea for production stage, you should write your own cors policies at production.

By the way it is written, clean rule is invoked only if it is explicitly called:

make clean

I think it is better, than make clean every time. If you want to do this by your way, try this:

CXX = g++ -O2 -Wall

all: clean code1 code2

code1: code1.cc utilities.cc
   $(CXX) $^ -o $@

code2: code2.cc utilities.cc
   $(CXX) $^ -o $@

clean: 
    rm ...
    echo Clean done

try this:

return $this->db->query("
     SELECT * FROM myTable 
     WHERE trans_id IN ( SELECT trans_id FROM myTable WHERE code='B') 
     AND code!='B'
     ")->result_array();

To make the images flexible, simply add max-width:100% and height:auto. Image max-width:100% and height:auto works in IE7, but not in IE8 (yes, another weird IE bug). To fix this, you need to add width:auto\9 for IE8.

source: http://webdesignerwall.com/tutorials/responsive-design-with-css3-media-queries

for example :

img {
    max-width: 100%;
    height: auto;
    width: auto\9; /* ie8 */
}

and then any images you add simply using the img tag will be flexible

JSFiddle example here. No JavaScript required. Works in latest versions of Chrome, Firefox and IE (which is all I've tested).

The solution by PeterVR has the disadvantage that the additional color displays on top of the entire HTML block - meaning that it also shows up on top of div content, not just on top of the background image. This is fine if your div is empty, but if it is not using a linear gradient might be a better solution:

<div class="the-div">Red text</div>

<style type="text/css">
  .the-div
  {
    background-image: url("the-image.png");
    color: #f00;
    margin: 10px;
    width: 200px;
    height: 80px;
  }
  .the-div:hover
  {
    background-image: linear-gradient(to bottom, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
    background-image: -moz-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
    background-image: -o-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
    background-image: -ms-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
    background-image: -webkit-gradient(linear, left top, left bottom, from(rgba(0, 0, 0, 0.1)), to(rgba(0, 0, 0, 0.1))), url("the-image.png");
    background-image: -webkit-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
  }
</style>

See fiddle. Too bad that gradient specifications are currently a mess. See compatibility table, the code above should work in any browser with a noteworthy market share - with the exception of MSIE 9.0 and older.

Edit (March 2017): The state of the web got far less messy by now. So the linear-gradient (supported by Firefox and Internet Explorer) and -webkit-linear-gradient (supported by Chrome, Opera and Safari) lines are sufficient, additional prefixed versions are no longer necessary.

Not an answer here and more like a comment, sorry but I can't comment.

In node V10, you can use the flag --experimental-modules to tell Nodejs you want to use import. But your entry script should end with .mjs.

Note this is still an experimental thing and should not be used in production.

// main.mjs
import utils from './utils.js'
utils.print();

// utils.js
module.exports={
    print:function(){console.log('print called')}
}

Exception object also contains original response e.response, that could be useful if need to see error body in response from the server. For example:

    r.raise_for_status()
except requests.exceptions.HTTPError as e:

In the original post author concatenated strings. Every sting operation will result in string recreation in .Net. String is effectively a reference type. As a result, the function provided will be visibly slow. Don't do that. Use array of chars instead, write there directly and then convert result to string. In my case of processing 500 kb of text difference is almost 5 minutes.

Have you tried setting the selection properties of your tableView like this:

tableView.allowsMultipleSelection = NO; tableView.allowsMultipleSelectionDuringEditing = YES; tableView.allowsSelection = NO; tableView.allowsSelectionDuringEditing YES; 

If you want more fine-grain control over when selection is allowed you can override - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath in your UITableView delegate. The documentation states:

Return Value An index-path object that confirms or alters the selected row. Return an NSIndexPath object other than indexPath if you want another cell to be selected. Return nil if you don't want the row selected. 

You can have this method return nil in cases where you don't want the selection to happen.

Okay, but you all know that the * is a wildcard and allows cross site scripting from every domain?

You would like to send multiple Access-Control-Allow-Origin headers for every site that's allowed to - but unfortunately its officially not supported to send multiple Access-Control-Allow-Origin headers, or to put in multiple origins.

You can solve this by checking the origin, and sending back that one in the header, if it is allowed:

$origin = $_SERVER['HTTP_ORIGIN'];
$allowed_domains = [
    'http://mysite1.com',
    'https://www.mysite2.com',
    'http://www.mysite2.com',
];

if (in_array($origin, $allowed_domains)) {
    header('Access-Control-Allow-Origin: ' . $origin);
}

Thats much safer. You might want to edit the matching and change it to a manual function with some regex, or something like that. At least this will only send back 1 header, and you will be sure its the one that the request came from. Please do note that all HTTP headers can be spoofed, but this header is for the client's protection. Don't protect your own data with those values. If you want to know more, read up a bit on CORS and CSRF.

Why is it safer?

Allowing access from other locations then your own trusted site allows for session highjacking. I'm going to go with a little example - image Facebook allows a wildcard origin - this means that you can make your own website somewhere, and make it fire AJAX calls (or open iframes) to facebook. This means you can grab the logged in info of the facebook of a visitor of your website. Even worse - you can script POST requests and post data on someone's facebook - just while they are browsing your website.

Be very cautious when using the ACAO headers!

Spring (nowadays) makes it easy to add Spring to a project by using just one dependency, e.g.

<dependency>

</dependency> 

This will resolve to

After checking the source code, I found that for the example:

FileReader fReader = new FileReader(fileName);
BufferedReader bReader = new BufferedReader(fReader);

the close() method on BufferedReader object would call the abstract close() method of Reader class which would ultimately call the implemented method in InputStreamReader class, which then closes the InputStream object.

So, only bReader.close() is sufficient.

I made a collection layout.

To make the separator visible, Set the background color of the collection view to gray. One row per section.

Useage:

let layout = GridCollectionViewLayout()
layout.cellHeight = 50 // if not set, cellHeight = Collection.height/numberOfSections
layout.cellWidth = 50  // if not set, cellWidth = Collection.width/numberOfItems(inSection)
collectionView.collectionViewLayout = layout

Layout:

import UIKit

class GridCollectionViewLayout: UICollectionViewLayout {


var cellWidth : CGFloat = 0
var cellHeight : CGFloat = 0
var seperator: CGFloat = 1

private var cache = [UICollectionViewLayoutAttributes]()



override func prepare() {

    guard let collectionView = self.collectionView else {
        return
    }

    self.cache.removeAll()



        let numberOfSections = collectionView.numberOfSections

        if cellHeight <= 0
        {
            cellHeight = (collectionView.bounds.height - seperator*CGFloat(numberOfSections-1))/CGFloat(numberOfSections)
        }

        for section in 0..<collectionView.numberOfSections {

            let numberOfItems = collectionView.numberOfItems(inSection: section)

            let cellWidth2 : CGFloat
            if cellWidth <= 0
            {
                cellWidth2 = (collectionView.bounds.width - seperator*CGFloat(numberOfItems-1))/CGFloat(numberOfItems)
            }
            else
            {
                cellWidth2 = cellWidth
            }


            for row in 0..<numberOfItems {


                let indexPath = NSIndexPath(row: row, section: section)

                let attributes = UICollectionViewLayoutAttributes(forCellWith: indexPath as IndexPath)
                attributes.frame = CGRect(x: (cellWidth2+seperator)*CGFloat(row),
                                          y: (cellHeight+seperator)*CGFloat(section),
                                          width: cellWidth2,

Request.Url.PathAndQuery

should work perfectly, especially if you only want the relative Uri (but keeping querystrings)

I write some test code:

#include <string>
#include <iostream>
#include <stdio.h>

using namespace std;

struct sc {
    int x;
    string y;
    int* z;
};

int main(int argc, char** argv)
{
   int* r = new int[128];
   for(int i = 0; i < 128; i++ ) {
        r[i] = i+32;
   }
   cout << r[100] << endl;
   delete r;

   sc* a = new sc;
   sc* aa = new sc[2];
   sc* b = new sc();
   sc* ba = new sc[2]();

   cout << "az:" << a->z << endl;
   cout << "bz:" << b->z << endl;
   cout << "a:" << a->x << " y" << a->y << "end" << endl;
   cout << "b:" << b->x << " y" << b->y <<  "end" <<endl;
   cout << "aa:" << aa->x << " y" << aa->y <<  "end" <<endl;
   cout << "ba:" << ba->x << " y" << ba->y <<  "end" <<endl;
}

g++ compile and run:

./a.out 
132
az:0x2b0000002a
bz:0
a:854191480 yend
b:0 yend
aa:854190968 yend
ba:0 yend

for simple comments:

set serveroutput on format wrapped;
begin
    DBMS_OUTPUT.put_line('simple comment');
end;
/

-- do something

begin
    DBMS_OUTPUT.put_line('second simple comment');
end;
/

you should get:

anonymous block completed
simple comment

anonymous block completed
second simple comment

if you want to print out the results of variables, here's another example:

set serveroutput on format wrapped;
declare
a_comment VARCHAR2(200) :='first comment';
begin
    DBMS_OUTPUT.put_line(a_comment);
end;

/

-- do something


declare
a_comment VARCHAR2(200) :='comment';
begin
    DBMS_OUTPUT.put_line(a_comment || 2);
end;

your output should be:

anonymous block completed
first comment

anonymous block completed
comment2

You can do this,

User.query.filter_by(id=123).delete()

or

User.query.filter(User.id == 123).delete()

Make sure to commit for delete() to take effect.

Image class has PropertyItems and PropertyIdList properties. You can use them.

I've tried to enable custom errors on production server for 3 hours, seems I found final solution how to do this in ASP.NET MVC without any routes.

To enable custom errors in ASP.NET MVC application we need (IIS 7+):

1. Configure custom pages in web config under system.web section:

   <customErrors mode="RemoteOnly"  defaultRedirect="~/error">
       <error statusCode="404" redirect="~/error/Error404" />
       <error statusCode="500" redirect="~/error" />
   </customErrors>
   

   RemoteOnly means that on local network you will see real errors (very useful during development). We can also rewrite error page for any error code.

2. Set magic Response parameter and response status code (in error handling module or in error handle attribute)

     HttpContext.Current.Response.StatusCode = 500;
     HttpContext.Current.Response.TrySkipIisCustomErrors = true;
   

3. Set another magic setting in web config under system.webServer section:

   <httpErrors errorMode="Detailed" />
   

This was final thing that I've found and after this I can see custom errors on production server.

To change even less on your original query, you can turn your join into a RIGHT join

SELECT person.person_id, COUNT(appointment.person_id) AS "number_of_appointments"
FROM appointment
RIGHT JOIN person ON person.person_id = appointment.person_id
GROUP BY person.person_id;

This just builds on the selected answer, but as the outer join is in the RIGHT direction, only one word needs to be added and less changes. - Just remember that it's there and can sometimes make queries more readable and require less rebuilding.

Remove the required: true rule.

Demo: Fiddle

jQuery('.validatedForm').validate({
            rules : {
                password : {
                    minlength : 5
                },
                password_confirm : {
                    minlength : 5,
                    equalTo : "#password"
                }
            }

Using nltk.

from nltk.tokenize import sent_tokenize, word_tokenize
sentences = sent_tokenize("This is a string.")
words_in_each_sentence = word_tokenize(sentences)

You may use TweetTokenizer for parsing casual text with emoticons and such.

The problem is that you haven't got any element with the id u so that you are calling something that doesn't exist.
To fix that you have to add an id to the element.

<input id="u" type="text" class="searchbox1" name="search" placeholder="Search for Brand, Store or an Item..." value="text" />

And I've seen too you have added a value for the input, so it means the input is not empty and it will contain text. As result placeholder won't be displayed.

Finally there is a warning that W3Validator will say because of the "/" in the end. :

For the current document, the validator interprets strings like according to legacy rules that break the expectations of most authors and thus cause confusing warnings and error messages from the validator. This interpretation is triggered by HTML 4 documents or other SGML-based HTML documents. To avoid the messages, simply remove the "/" character in such contexts. NB: If you expect <FOO /> to be interpreted as an XML-compatible "self-closing" tag, then you need to use XHTML or HTML5.

In conclusion it says you have to remove the slash. Simply write this:

<input id="u" type="text" class="searchbox1" name="search" placeholder="Search for Brand, Store or an Item...">

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

In pseudocode, he wants to do:

let myController = instantiate(someParentController)

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

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

Am I getting his question wrong?

For information
if anyone use

$('#formId').submit();

Do not something like this

<button name = "submit">

It took many hours to find me that submit() won't work like this.

Note - This is not a solution to the original question. This is a solution to one of the subproblems discussed above.

Solution to @andr Clarification 2 -

Its really problematic when there's only one marker in the bounds and due to it the zoom level is set to a very high level (level 21). And Google does not provide any way to set the max zoom level at this point. This can also happen when there are more than 1 marker but they are all pretty close to each other. Then also the same problem will occur.

Solution - Suppose you want your Map to never go beyond 16 zoom level. Then after doing -

CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, padding);
mMap.moveCamera(cu);

Check if your zoom level has crossed level 16(or whatever you want) -

float currentZoom = mMap.getCameraPosition().zoom;

And if this level is greater than 16, which it will only be if there are very less markers or all the markers are very close to each other, then simply zoom out your map at that particular position only by seting the zoom level to 16.

mMap.moveCamera(CameraUpdateFactory.zoomTo(16));

This way you'll never have the problem of "bizarre" zoom level explained very well by @andr too.

    Object[] objArray = arrayList.toArray();

    //display contents of Object array
    System.out.println("ArrayList elements are copied into an Array.
                                                  Now Array Contains..");
    for(int index=0; index < objArray.length ; index++)
      System.out.println(objArray[index]);

For JS:

First, if you haven't installed telegram bot just install with the command

npm i messaging-api-telegram

Now, initialize its client with

const client = new TelegramClient({
    accessToken: process.env.<TELEGRAM_ACCESS_TOKEN>
});

Then, to send message use sendMessage() async function like below -

    const resp = await client.sendMessage(chatId, msg, {
        disableWebPagePreview: false,
        disableNotification: false,
        parseMode: "HTML"
    });

Here parse mode by default would be plain text but with parseOptions parseMode we can do 1. "HTML" and "MARKDOWN" to let use send messages in stylish way. Also get your access token of bot from telegram page and chatId or group chat Id from same.

If you don't care about the columns where the missing files are, considering that the dataframe has the name New and one wants to assign the new dataframe to the same variable, simply run

New = New.drop_duplicates()

If you specifically want to remove the rows for the empty values in the column Tenant this will do the work

New = New[New.Tenant != '']

This may also be used for removing rows with a specific value - just change the string to the value that one wants.

Note: If instead of an empty string one has NaN, then

New = New.dropna(subset=['Tenant'])

How do I emulate the ISNULL() functionality ?

SELECT (Field IS NULL) FROM ...

No. gettimeofday should NEVER be used to measure time.

This is causing bugs all over the place. Please don't add more bugs.

a. You can use environment variables via terminal:

$ docker run -d --name container_name \
      -e MONGO_INITDB_ROOT_USERNAME=admin \
      -e MONGO_INITDB_ROOT_PASSWORD=password \
      mongo

If you like to test if everything works:

// ssh into the running container
// Change container name if necessary
$ docker exec -it mongo /bin/bash

// Enter into mongo shell
$ mongo

// Caret will change when you enter successfully
// Switch to admin database
$> use admin
$> db.auth("admin", passwordPrompt())

// Show available databases
$> show dbs

If you like to instantiate a database on first run, check option b.

b. You can use environment variables in your docker stack deploy file or compose file for versions 3.4 through 4.1.

As it is explained on the quick reference section of the official mongo image set MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD in your yaml file:

mongo:
    image: mongo
    environment:
      MONGO_INITDB_ROOT_USERNAME: admin
      MONGO_INITDB_ROOT_PASSWORD: password

docker-entrypoint.sh file in mongo image checks for the existence of these two variables and sets --auth flag accordingly.

c. You can also use docker secrets.

MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD is set indirectly by docker-entrypoint.sh from MONGO_INITDB_ROOT_USERNAME_FILE and MONGO_INITDB_ROOT_PASSWORD_FILE variables:

mongo:
    image: mongo
    environment:
        - MONGO_INITDB_ROOT_USERNAME_FILE=/run/secrets/db_root_username
        - MONGO_INITDB_ROOT_PASSWORD_FILE=/run/secrets/db_root_password
    secrets:
      - db_root_username
      - db_root_password

docker-entrypoint.sh converts MONGO_INITDB_ROOT_USERNAME_FILE and MONGO_INITDB_ROOT_PASSWORD_FILE to MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD.

You can use MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD in your .sh or .js scripts in docker-entrypoint-initdb.d folder while initializing database instance.

When a container is started for the first time it will execute files with extensions .sh and .js that are found in /docker-entrypoint-initdb.d. Files will be executed in alphabetical order. .js files will be executed by mongo using the database specified by the MONGO_INITDB_DATABASE variable, if it is present, or test otherwise. You may also switch databases within the .js script.

This last method is not in the reference docs, so it may not survive an update.

You can also use the Termial view to ssh/telnet to your local machine. Doesn't have that funny input box for commands.

Here is the basic example to demonstrate the Python string formatting and a new way to do it.

my_word = 'epic'
my_number = 1

print('The %s number is %d.' % (my_word, my_number))  # traditional substitution with % operator

//The epic number is 1.

print(f'The {my_word} number is {my_number}.')  # newer format string style

//The epic number is 1.

Both prints the same.

Jason's code can not be used for elements inside an iframe (as the scope differs from window and document). I fixed that problem and I modified it in order to be used as any other jQuery plugin (chainable):

Example 1: Selection of all text inside < code > tags with single click and add class "selected":

$(function() {
    $("code").click(function() {
        $(this).selText().addClass("selected");
    });
});

Example 2: On button click, select an element inside an Iframe:

$(function() {
    $("button").click(function() {
        $("iframe").contents().find("#selectme").selText();
    });
});

Note: remember that the iframe source should reside in the same domain to prevent security errors.

jQuery Plugin:

jQuery.fn.selText = function() {
    var obj = this[0];
    if ($.browser.msie) {
        var range = obj.offsetParent.createTextRange();
        range.moveToElementText(obj);
        range.select();
    } else if ($.browser.mozilla || $.browser.opera) {
        var selection = obj.ownerDocument.defaultView.getSelection();
        var range = obj.ownerDocument.createRange();
        range.selectNodeContents(obj);
        selection.removeAllRanges();
        selection.addRange(range);
    } else if ($.browser.safari) {
        var selection = obj.ownerDocument.defaultView.getSelection();
        selection.setBaseAndExtent(obj, 0, obj, 1);
    }
    return this;
}

I tested it in IE8, Firefox, Opera, Safari, Chrome (current versions). I'm not sure if it works in older IE versions (sincerely I don't care).

I believe that although javascript is an option here, you have a smoother animation through forcing hardware accelerate with CSS3. You can achieve this by setting the following CSS3 properties on the moving div:

div.hardware-accelarate {
     -webkit-transform: translate3d(0,0,0);
        -moz-transform: translate3d(0,0,0);
         -ms-transform: translate3d(0,0,0);
          -o-transform: translate3d(0,0,0);
             transform: translate3d(0,0,0);
}

I've made a plunkr setup for ya'll to test and tweak...

I had the same error message, and the problem was also the metadata part of the connection string, but I had to dig a little deeper to solve it and wanted to share this little nugget:

The metadata string is made up of three sections that each look like this:

res://
      (assembly)/
      (model name).(ext)

Where ext is "csdl", "ssdl", and "msl".

For most people, assembly can probably be "*", which seems to indicate that all loaded assemblies will be searched (I haven't done a huge amount of testing of this). This part wasn't an issue for me, so I can't comment on whether you need the assembly name or file name (i.e., with or without ".dll"), though I have seen both suggested.

The model name part should be the name and namespace of your .edmx file, relative to your assembly. So if you have a My.DataAccess assembly and you create DataModels.edmx in a Models folder, its full name is My.DataAccess.Models.DataModels. In this case, you would have "Models.DataModels.(ext)" in your metadata.

If you ever move or rename your .edmx file, you will need to update your metadata string manually (in my experience), and remembering to change the relative namespace will save a few headaches.

Regarding the question,

” can someone explain why the compare() function exists if a comparison can be made using simple operands?

Relative to < and ==, the compare function is conceptually simpler and in practice it can be more efficient since it avoids two comparisons per item for ordinary ordering of items.

As an example of simplicity, for small integer values you can write a compare function like this:

auto compare( int a, int b ) -> int { return a - b; }

which is highly efficient.

Now for a structure

struct Foo
{
    int a;
    int b;
    int c;
};

auto compare( Foo const& x, Foo const& y )
    -> int
{
    if( int const r = compare( x.a, y.a ) ) { return r; }
    if( int const r = compare( x.b, y.b ) ) { return r; }
    return compare( x.c, y.c );
}

Trying to express this lexicographic compare directly in terms of < you wind up with horrendous complexity and inefficiency, relatively speaking.

With C++11, for the simplicity alone ordinary less-than comparison based lexicographic compare can be very simply implemented in terms of tuple comparison.

You can set the hours, minutes, seconds and microseconds to whatever you like

datetime.datetime.today().replace(hour=0, minute=0, second=0, microsecond=0)

but trutheality's answer is probably best when they are all to be zero and you can just compare the .date()s of the times

Maybe it is faster though if you have to compare hundreds of datetimes because you only need to do the replace() once vs hundreds of calls to date()

Generally, Postman used for debugging and used in the development phase. But in case you want to block it even from postman try this.

    const referrer_domain = "[enter-the-domain-name-of-the-referrer]"
    //check for the referrer domain
    app.all('/*', function(req, res, next) {
      if(req.headers.referer.indexOf(referrer_domain) == -1){
        res.send('Invalid Request')
      }

      next();
    });

Based on @Haroldo Macêdo's answer, I created a method in my custom Utils class such as

/**
 * Left padding a string with the given character
 *
 * @param str     The string to be padded
 * @param length  The total fix length of the string
 * @param padChar The pad character
 * @return The padded string
 */
public static String padLeft(String str, int length, String padChar) {
    String pad = "";
    for (int i = 0; i < length; i++) {
        pad += padChar;
    }
    return pad.substring(str.length()) + str;
}

Then call Utils.padLeft(str, 10, "0");

I know this is an old question, however, it is useful to mention the new features in the latest version.

From Oracle 12c onwards, you could use the new Top-n Row limiting feature. No need to write a subquery, no dependency on ROWNUM.

For example, the below query would return the employees between 4th highest till 7th highest salaries in ascending order:

SQL> SELECT empno, sal
  2  FROM   emp
  3  ORDER BY sal
  4  OFFSET 4 ROWS FETCH NEXT 4 ROWS ONLY;

     EMPNO        SAL
---------- ----------
      7654       1250
      7934       1300
      7844       1500
      7499       1600

SQL>

There are a few ways to do this.

The first is the most widely used. It works on all major browsers.

input[readonly] {
 background-color: #dddddd;
}

While the one above will select all inputs with readonly attached, this one below will select only what you desire. Make sure to replace demo with whatever input type you want.

input[type="demo"]:read-only {
 background-color: #dddddd;
}

This is an alternate to the first, but it's not used a whole lot:

input:read-only {
 background-color: #dddddd;
}

The :read-only selector is supported in Chrome, Opera, and Safari. Firefox uses :-moz-read-only. IE doesn't support the :read-only selector.

You can also use input[readonly="readonly"], but this is pretty much the same as input[readonly], from my experience.

You can hide the modal and popup the window to review the carts in validateShipping() function itself.

function validateShipping(){
...
...
$('#product-options').modal('hide');
//pop the window to select items
}

Add a prop 'key' to the rendering root component of the list.

<ScrollView>
      <List>
          {this.state.nationalities.map((prop, key) => {
             return (
               <ListItem key={key}>
                  <Text>{prop.name}</Text>
               </ListItem>
             );
          })}
      </List>
</ScrollView>

You can undo git add before commit with

git reset <file>

which will remove it from the current index (the "about to be committed" list) without changing anything else.

You can use

git reset

without any file name to unstage all due changes. This can come in handy when there are too many files to be listed one by one in a reasonable amount of time.

In old versions of Git, the above commands are equivalent to git reset HEAD <file> and git reset HEAD respectively, and will fail if HEAD is undefined (because you haven't yet made any commits in your repository) or ambiguous (because you created a branch called HEAD, which is a stupid thing that you shouldn't do). This was changed in Git 1.8.2, though, so in modern versions of Git you can use the commands above even prior to making your first commit:

"git reset" (without options or parameters) used to error out when you do not have any commits in your history, but it now gives you an empty index (to match non-existent commit you are not even on).

Documentation: git reset

Another alternative is pushd, which will automatically switch drives as needed. It also allows you to return to the previous directory via popd:

C:\Temp>pushd D:\some\folder

D:\some\folder>popd

C:\Temp>_

Angular 2 Beta

This answer is for those who use Javascript for angularJS v.2.0 Beta.

To use ngModel in your view you should tell the angular's compiler that you are using a directive called ngModel.

How?

To use ngModel there are two libraries in angular2 Beta, and they are ng.common.FORM_DIRECTIVES and ng.common.NgModel.

Actually ng.common.FORM_DIRECTIVES is nothing but group of directives which are useful when you are creating a form. It includes NgModel directive also.

app.myApp = ng.core.Component({
    selector: 'my-app',
    templateUrl: 'App/Pages/myApp.html',
    directives: [ng.common.NgModel] // specify all your directives here
}).Class({
    constructor: function () {
        this.myVar = {};
        this.myVar.text = "Testing";
    },

});

The clean way to use mbstowcs is to call it twice to find the length of the result:

  const char * cs = <your input char*>
  size_t wn = mbsrtowcs(NULL, &cs, 0, NULL);

  // error if wn == size_t(-1)

  wchar_t * buf = new wchar_t[wn + 1]();  // value-initialize to 0 (see below)

  wn = mbsrtowcs(buf, &cs, wn + 1, NULL);

  // error if wn == size_t(-1)

  assert(cs == NULL); // successful conversion

  // result now in buf, return e.g. as std::wstring

  delete[] buf;

Don't forget to call setlocale(LC_CTYPE, ""); at the beginning of your program!

The advantage over the Windows MultiByteToWideChar is that this is entirely standard C, although on Windows you might prefer the Windows API function anyway.

I usually wrap this method, along with the opposite one, in two conversion functions string->wstring and wstring->string. If you also add trivial overloads string->string and wstring->wstring, you can easily write code that compiles with the Winapi TCHAR typedef in any setting.

[Edit:] I added zero-initialization to buf, in case you plan to use the C array directly. I would usually return the result as std::wstring(buf, wn), though, but do beware if you plan on using C-style null-terminated arrays.[/]

In a multithreaded environment you should pass a thread-local conversion state to the function as its final (currently invisible) parameter.

Here is a small rant of mine on this topic.

if you are getting id from url try

$id = (isset($_GET['id']) ? $_GET['id'] : '');

if getting from form you need to use POST method cause your form has method="post"

 $id = (isset($_POST['id']) ? $_POST['id'] : '');

For php notices use isset() or empty() to check values exist or not or initialize variable first with blank or a value

$id= '';

If you want to drop rows of data frame on the basis of some complicated condition on the column value then writing that in the way shown above can be complicated. I have the following simpler solution which always works. Let us assume that you want to drop the column with 'header' so get that column in a list first.

text_data = df['name'].tolist()

now apply some function on the every element of the list and put that in a panda series:

text_length = pd.Series([func(t) for t in text_data])

in my case I was just trying to get the number of tokens:

text_length = pd.Series([len(t.split()) for t in text_data])

now add one extra column with the above series in the data frame:

df = df.assign(text_length = text_length .values)

now we can apply condition on the new column such as:

df = df[df.text_length  >  10]

def pass_filter(df, label, length, pass_type):

    text_data = df[label].tolist()

    text_length = pd.Series([len(t.split()) for t in text_data])

    df = df.assign(text_length = text_length .values)

    if pass_type == 'high':
        df = df[df.text_length  >  length]

    if pass_type == 'low':
        df = df[df.text_length  <  length]

    df = df.drop(columns=['text_length'])

    return df

As mentioned above by others,

Scrum is an iterative and incremental agile software development method for managing software projects and product or application development. So Scrum is in fact a type of Agile approach which is used widely in software developments.

So, Scrum is a specific flavor of Agile, specifically it is referred to as an agile project management framework.

Also Scrum has mainly two roles inside it, which are: 1. Main/Core Role 2. Ancillary Role

Main/Core role: It consists of mainly three roles: a). Scrum Master, b). Product Owner, c). Development Team.

Ancillary Role: The ancillary roles in Scrum teams are those with no formal role and infrequent involvement in the Scrum procession but nonetheless, they must be taken into account. viz. Stakeholders, Managers.

Scrum Master:- There are 6 types of meetings in scrum:

• Daily Scrum / Standup
• Backlog grooming: storyline
• Scrum of Scrums
• Sprint Planning meeting
• Sprint review meeting
• Sprint retrospective

Let me know if any one need more inputs on this.

You should also properly configure the maximum memory allocations for MapReduce. From this HortonWorks tutorial:

[...]

Each machine in our cluster has 48 GB of RAM. Some of this RAM should be >reserved for Operating System usage. On each node, we’ll assign 40 GB RAM for >YARN to use and keep 8 GB for the Operating System

For our example cluster, we have the minimum RAM for a Container (yarn.scheduler.minimum-allocation-mb) = 2 GB. We’ll thus assign 4 GB for Map task Containers, and 8 GB for Reduce tasks Containers.

In mapred-site.xml:

mapreduce.map.memory.mb: 4096

mapreduce.reduce.memory.mb: 8192

Each Container will run JVMs for the Map and Reduce tasks. The JVM heap size should be set to lower than the Map and Reduce memory defined above, so that they are within the bounds of the Container memory allocated by YARN.

In mapred-site.xml:

mapreduce.map.java.opts: -Xmx3072m

mapreduce.reduce.java.opts: -Xmx6144m

The above settings configure the upper limit of the physical RAM that Map and Reduce tasks will use.

To sum it up:

1. In YARN, you should use the mapreduce configs, not the mapred ones. EDIT: This comment is not applicable anymore now that you've edited your question.
2. What you are configuring is actually how much you want to request, not what is the max to allocate.
3. The max limits are configured with the java.opts settings listed above.

Finally, you may want to check this other SO question that describes a similar problem (and solution).

Have you heard of Duff's device? This is a great example of using switch fallthrough.

It's a feature that can be used and it can be abused, like almost all language features.

If you just want a light theme and aren't particular about the specific color, then you can pass a theme id to the AlertDialog.Builder constructor.

AlertDialog.Builder(this, AlertDialog.THEME_HOLO_LIGHT)...

or

AlertDialog.Builder(this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT)...

Unless you redirect stdout and stderr as the accepted answer suggests, this is not possible with execSync or spawnSync. Without redirecting stdout and stderr those commands only return stdout and stderr when the command is completed.

To do this without redirecting stdout and stderr, you are going to need to use spawn to do this but it's pretty straight forward:

var spawn = require('child_process').spawn;

//kick off process of listing files
var child = spawn('ls', ['-l', '/']);

//spit stdout to screen
child.stdout.on('data', function (data) {   process.stdout.write(data.toString());  });

//spit stderr to screen
child.stderr.on('data', function (data) {   process.stdout.write(data.toString());  });

child.on('close', function (code) { 
    console.log("Finished with code " + code);
});

I used an ls command that recursively lists files so that you can test it quickly. Spawn takes as first argument the executable name you are trying to run and as it's second argument it takes an array of strings representing each parameter you want to pass to that executable.

However, if you are set on using execSync and can't redirect stdout or stderr for some reason, you can open up another terminal like xterm and pass it a command like so:

var execSync = require('child_process').execSync;

execSync("xterm -title RecursiveFileListing -e ls -latkR /");

This will allow you to see what your command is doing in the new terminal but still have the synchronous call.

You want to use the ParameterizedThreadStart delegate for thread methods that take parameters. (Or none at all actually, and let the Thread constructor infer.)

Example usage:

var thread = new Thread(new ParameterizedThreadStart(download));
//var thread = new Thread(download); // equivalent

thread.Start(filename)

In your JSOn file, please make below change.

    }

And after that:

 this.http.get(url).map(res:Response) => res.json().data);

The data is actually the name of tge collection of json file. Please try the code above, I am sure it will work.

 // Define appendVal by extending JQuery_x000D_
 $.fn.appendVal = function( TextToAppend ) {_x000D_
  return $(this).val(_x000D_
   $(this).val() + TextToAppend_x000D_
  );_x000D_
 };_x000D_
//______________________________________________x000D_
_x000D_
 // And that's how to use it:_x000D_
 $('#SomeID')_x000D_
  .appendVal( 'This text was just added' )

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<form>_x000D_
<textarea _x000D_
          id    =  "SomeID"_x000D_
          value =  "ValueText"_x000D_
          type  =  "text"_x000D_
>Current NodeText_x000D_
</textarea>_x000D_
  </form>

Well when creating this example I somehow got a little confused. "ValueText" vs >Current NodeText< Isn't .val() supposed to run on the data of the value attribute? Anyway I and you me may clear up this sooner or later.

However the point for now is:

When working with form data use .val().

When dealing with the mostly read only data in between the tag use .text() or .append() to append text.

You can use the MsiEnumProductsEx and MsiGetProductInfoEx methods to enumerate all the installed applications on your system and match the data to your application

Well, actually, React is not suitable for calling child methods from the parent. Some frameworks, like Cycle.js, allow easily access data both from parent and child, and react to it.

Also, there is a good chance you don't really need it. Consider calling it into existing component, it is much more independent solution. But sometimes you still need it, and then you have few choices:

• Pass method down, if it is a child (the easiest one, and it is one of the passed properties)
• add events library; in React ecosystem Flux approach is the most known, with Redux library. You separate all events into separated state and actions, and dispatch them from components
• if you need to use function from the child in a parent component, you can wrap in a third component, and clone parent with augmented props.

UPD: if you need to share some functionality which doesn't involve any state (like static functions in OOP), then there is no need to contain it inside components. Just declare it separately and invoke when need:

let counter = 0;
function handleInstantiate() {
   counter++;
}

constructor(props) {
   super(props);
   handleInstantiate();
}

y-combinator in JavaScript:

var Y = function(f) {
  return (function(g) {
    return g(g);
  })(function(h) {
    return function() {
      return f(h(h)).apply(null, arguments);
    };
  });
};

var factorial = Y(function(recurse) {
  return function(x) {
    return x == 0 ? 1 : x * recurse(x-1);
  };
});

factorial(5)  // -> 120

Edit: I learn a lot from looking at code, but this one is a bit tough to swallow without some background - sorry about that. With some general knowledge presented by other answers, you can begin to pick apart what is happening.

The Y function is the "y-combinator". Now take a look at the var factorial line where Y is used. Notice you pass a function to it that has a parameter (in this example, recurse) that is also used later on in the inner function. The parameter name basically becomes the name of the inner function allowing it to perform a recursive call (since it uses recurse() in it's definition.) The y-combinator performs the magic of associating the otherwise anonymous inner function with the parameter name of the function passed to Y.

For the full explanation of how Y does the magic, checked out the linked article (not by me btw.)

Please refer below TSQL. STRING_SPLIT function is available only under compatibility level 130 and above.

TSQL:

DECLARE @stringValue NVARCHAR(400) = 'red,blue,green,yellow,black'  
DECLARE @separator CHAR = ','

SELECT [value]  As Colour
FROM STRING_SPLIT(@stringValue, @separator); 

RESULT:

Colour

red blue green yellow black

With Python 3, how about:

try:
    with open(filename, 'x') as tempfile: # OSError if file exists or is invalid
        pass
except OSError:
    # handle error here

With the 'x' option we also don't have to worry about race conditions. See documentation here.

Now, this WILL create a very shortlived temporary file if it does not exist already - unless the name is invalid. If you can live with that, it simplifies things a lot.

There is fundamental difference between query parameters and path parameters. It goes like this: www.your_domain?queryparam1=1&queryparam2=2 - query parameters. www.your_domain/path_param1/entity/path_param2 - path parameters.

What I found surprising is that in Spring MVC world a lot of people confuse one for the other. While query parameters are more like criteria for a search, path params will most likely uniquely identify a resource. Having said that, it doesn't mean that you can't have multiple path parameters in your URI, because the resource structure can be nested. For example, let's say you need a specific car resource of a specific person:

www.my_site/customer/15/car/2 - looking for a second car of a 15th customer.

What would be a usecase to put all path parameters into a map? Path parameters don't have a "key" when you look at a URI itself, those keys inside the map would be taken from your @Mapping annotation, for example:

@GetMapping("/booking/{param1}/{param2}")

From HTTP/REST perspective path parameters can't be projected onto a map really. It's all about Spring's flexibility and their desire to accommodate any developers whim, in my opinion.

I would never use a map for path parameters, but it can be quite useful for query parameters.

I think I have a solution to the password problem. This single argument is truly amazing. It asks for the password once, and than never asks for it again. Even if you put it onto another program, it will not ask for the password. Here it is:

runas /user:Administrator /savecred Example1Server.exe

I found a workaround a week ago. You can use direct commands with "ExecuteCommand":

MDataContext dc = new MDataContext();
var flag = (from f in dc.Flags
                   where f.Code == Code
                   select f).First();
_refresh = Convert.ToBoolean(flagRefresh.Value);
if (_refresh)
{
    dc.ExecuteCommand("update Flags set value = 0 where code = {0}", Code);
}

In the ExecuteCommand statement, you can send the query directly, with the value for the specific record you want to update.

value = 0 --> 0 is the new value for the record;

code = {0} --> is the field where you will send the filter value;

Code --> is the new value for the field;

I hope this reference helps.

The biggest difference is their functionality. push_back always puts a new element at the end of the vector and insert allows you to select new element's position. This impacts the performance. vector elements are moved in the memory only when it's necessary to increase it's length because too little memory was allocated for it. On the other hand insert forces to move all elements after the selected position of a new element. You simply have to make a place for it. This is why insert might often be less efficient than push_back.

Index the list then the dict.

AFAIK, you can't create a File from an assets file because these are stored in the apk, that means there is no path to an assets folder.

But, you can try to create that File using a buffer and the AssetManager (it provides access to an application's raw asset files).

Try to do something like:

AssetManager am = getAssets();
InputStream inputStream = am.open("myfoldername/myfilename");
File file = createFileFromInputStream(inputStream);

private File createFileFromInputStream(InputStream inputStream) {

   try{
      File f = new File(my_file_name);
      OutputStream outputStream = new FileOutputStream(f);
      byte buffer[] = new byte[1024];
      int length = 0;

      while((length=inputStream.read(buffer)) > 0) {
        outputStream.write(buffer,0,length);
      }

      outputStream.close();
      inputStream.close();

      return f;
   }catch (IOException e) {
         //Logging exception
   }

   return null;
}

Let me know about your progress.

In the terminal, use "mongo" command to switch the terminal into the MongoDB shell:

$ mongo
MongoDB shell version: 2.6.10
connecting to: admin
>

Once you get > symbol in the terminal, you have entered into the MongoDB shell.

We had a similar situation, but in our case Infosec agreed to allow any to 1, so we didnt had to fix the slave port, rather fixing the master to high level JNLP port 49187 worked ("Configure Global Security" -> "TCP port for JNLP slave agents").

I would style a link to look like a button, because that way there is a no-js fallback.

So this is how you could animate the jump using jquery. No-js fallback is a normal jump without animation.

Original example:

jsfiddle

$(document).ready(function() {_x000D_
  $(".jumper").on("click", function( e ) {_x000D_
_x000D_
    e.preventDefault();_x000D_
_x000D_
    $("body, html").animate({ _x000D_
      scrollTop: $( $(this).attr('href') ).offset().top _x000D_
    }, 600);_x000D_
_x000D_
  });_x000D_
});

#long {_x000D_
  height: 500px;_x000D_
  background-color: blue;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<!-- Links that trigger the jumping -->_x000D_
<a class="jumper" href="#pliip">Pliip</a>_x000D_
<a class="jumper" href="#ploop">Ploop</a>_x000D_
<div id="long">...</div>_x000D_
<!-- Landing elements -->_x000D_
<div id="pliip">pliip</div>_x000D_
<div id="ploop">ploop</div>

New example with actual button styles for the links, just to prove a point.

Everything is essentially the same, except that I changed the class .jumper to .button and I added css styling to make the links look like buttons.

Button styles example

BEGIN
  FOR r IN (select sid,serial# from v$session where username='user')
  LOOP
      EXECUTE IMMEDIATE 'alter system kill session ''' || r.sid  || ',' || r.serial# || '''';
  END LOOP;
END;
/

It works for me.

If you have Express.js, you can use express-mongo-db for caching and sharing the MongoDB connection between requests without a pool (since the accepted answer says it is the right way to share the connection).

If not - you can look at its source code and use it in another framework.

You need to use web services. In the above code I have php web service to be used which has a callback function which is optional. Assuming you know HTML5 I did not post the html code. In the url you can send the details to the web server.

Basically "delete" sends a query directly to the database to delete the record. In that case Rails doesn't know what attributes are in the record it is deleting nor if there are any callbacks (such as before_destroy).

The "destroy" method takes the passed id, fetches the model from the database using the "find" method, then calls destroy on that. This means the callbacks are triggered.

You would want to use "delete" if you don't want the callbacks to be triggered or you want better performance. Otherwise (and most of the time) you will want to use "destroy".

You can use DataSet.Tables(0).Columns.Contains(name) to check whether the DataTable contains a column with a particular name.

You can modify the .form-control:focus color without altering the bootstrap style in this way:

Quick fix

.form-control:focus {
        border-color: #28a745;
        box-shadow: 0 0 0 0.2rem rgba(40, 167, 69, 0.25);
    }

1. Find the bootstrapCDN version that you are using. E.g. for me right now is 4.3.1: https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.css
2. Search for the class you want to modify. E.g. .form-control:focus and copy the parameters that you want to modify into your css. In this case is border-color and box-shadow.
3. Choose a color for the border-color. In this case I choose to pick up the same green the bootstrap uses for their .btn-success class, by searching for that particular class in the bootstrap.css page mentioned in the step 1.
4. Convert the color you have picked to RGB and add that to the box-shadow parameter without altering the fourth RGBA parameter (0.25) that bootstrap has for transparency.

If you have BS4 another option could be:

.dropdown-item { 
  width: max-content !important;
}

.dropdown-menu {

    max-height: max-content;
    max-width: max-content;
}

The accepted answer above did not work for me, because it ordered the weeks by alphabetical order, not chronological order:

2012/1
2012/10
2012/11
...
2012/19
2012/2

Here's my solution to count and group by week:

SELECT CONCAT(YEAR(date), '/', WEEK(date)) AS week_name, 
       YEAR(date), WEEK(date), COUNT(*)
FROM column_name
GROUP BY week_name
ORDER BY YEAR(DATE) ASC, WEEK(date) ASC

Generates:

YEAR/WEEK   YEAR   WEEK   COUNT
2011/51     2011    51      15
2011/52     2011    52      14
2012/1      2012    1       20
2012/2      2012    2       14
2012/3      2012    3       19
2012/4      2012    4       19

$query = mysqli_query('SELECT TABLE_NAME FROM information_schema.TABLES WHERE TABLE_NAME IN ("table1","table2","table3") AND TABLE_SCHEMA="yourschema"');
$tablesExists = array();
while( null!==($row=mysqli_fetch_row($query)) ){
    $tablesExists[] = $row[0];
}

No, but since C++11 there is [u]int8_t.

For those who are using xampp:

File -> Preferences -> Settings

"php.validate.executablePath": "C:\\xampp\\php\\php.exe",
"php.executablePath": "C:\\xampp\\php\\php.exe"

UPDATE `Table A` a
SET a.`text`=(
        SELECT group_concat(b.`B-num`,' from ',b.`date` SEPARATOR ' / ') 
        FROM `Table B` b WHERE (a.`A-num`=b.`A-num`)
)

In addition to Richard Cresswells and dpbradleys answer: If you neither want to create a TNS name nor the '//123.45.67.89:1521/Test' input works (some configurations wont), you can put

(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 123.45.67.89)(PORT = 1521)) (CONNECT_DATA = (SID = TEST)(SERVER = DEDICATED)))

(as one line) into the 'database' section of the login dialog.

You can get it very easily by typing the following command on command promt

sudo chown -R www-data:www-data your_folder_name

or copy & paste the following code in your wp-config.php file.

define('FS_METHOD', 'direct');

Where "your_folder_name" is the folder where your WordPress is installed inside this folder.

Use a image style width and height 100% . This will do the trick, because the image can be resized based on the container.

Example:

<a class="navbar-brand" href="#" style="padding: 4px;margin:auto"> <img src="images/logo.png" style="height:100%;width: auto;" title="mycompanylogo"></a>

It seems despite the intrinsic limitations of the money datatype, if you're already using it (or have inherited it as I have) the answer to your question is, use DECIMAL.

You can use a list comprehension:

[x for x in j if x >= 5]

Until today, for since at least 3 months ago, I regularly encountered hundreds of tree conflicts when attempting to merge a branch back into the trunk (using TortoiseSVN 1.11). Whether rebased or not, BTW. I've been using TortoiseSVN since its v1, back in 2004, and I used to reintegrate branches all the time. Something must have happened recently I suppose?

So today I ran this simple experiment, and I found what was creating these crazy conflicts:

1. I forked off the trunk @393;
2. I modified tens of files randomly, as well as creating new ones;
3. I committed. Now @395 (a colleague forked off at 394 to perform his own stuff).
4. Then I tried to reintegrate the branch back into the trunk, test only; following TortoiseSVN's recommendation in the wizard: "to merge all revisions (reintegrate), leave that box empty". To achieve this, I right-clicked onto the trunk folder, and chose "TortoiseSVN > Merge, from /path/to/branch", and I left the rev range empty, as advised on the dialog.

Discussion: (see attachment)

all revisions... of what? Little did I know that the client must have been referring to "all revisions of the target! (trunk)", as, in the process of reintegrating that branch, I saw the mention "Merging revisions 1-HEAD"! OMG. Poor Devil, you're falling to your death here. That branch was born @393, can't you read its birth certificate, for God's sake?

Resolution:

1. Contrarily to what's advised by the wiz, do specify a range, that covers ALL revisions of...the branch's life! therefore, 394-HEAD;
2. now run that merge test again, and get a cigar. ().

Moral: I can't comprehend why they still haven't fixed that bug, because it is one, I'm sorry. I should take the time to report this with them.

If your textbox has an id attribute of "mytextbox", then you can get the length like this:

var myLength = $("#mytextbox").val().length;

• $("#mytextbox") finds the textbox by its id.
• .val() gets the value of the input element entered by the user, which is a string.
• .length gets the number of characters in the string.

You have a numpy array of strings, not floats. This is what is meant by dtype('<U9') -- a little endian encoded unicode string with up to 9 characters.

try:

return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))

However, you don't need numpy here at all. You can really just do:

return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)

Or if you're really set on using numpy.

return np.asarray(listOfEmb, dtype=float).mean()

This is the way I am using at this moment... it's very complicated but at least it handles all the possible situations. In case anyone is interested.

public final class MyFragment extends Fragment {
    private TextView vstup;
    private Bundle savedState = null;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.whatever, null);
        vstup = (TextView)v.findViewById(R.id.whatever);

        /* (...) */

        /* If the Fragment was destroyed inbetween (screen rotation), we need to recover the savedState first */
        /* However, if it was not, it stays in the instance from the last onDestroyView() and we don't want to overwrite it */
        if(savedInstanceState != null && savedState == null) {
            savedState = savedInstanceState.getBundle(App.STAV);
        }
        if(savedState != null) {
            vstup.setText(savedState.getCharSequence(App.VSTUP));
        }
        savedState = null;

        return v;
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        savedState = saveState(); /* vstup defined here for sure */
        vstup = null;
    }

    private Bundle saveState() { /* called either from onDestroyView() or onSaveInstanceState() */
        Bundle state = new Bundle();
        state.putCharSequence(App.VSTUP, vstup.getText());
        return state;
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        /* If onDestroyView() is called first, we can use the previously savedState but we can't call saveState() anymore */
        /* If onSaveInstanceState() is called first, we don't have savedState, so we need to call saveState() */
        /* => (?:) operator inevitable! */
        outState.putBundle(App.STAV, (savedState != null) ? savedState : saveState());
    }

    /* (...) */

}

Alternatively, it is always a possibility to keep the data displayed in passive Views in variables and using the Views only for displaying them, keeping the two things in sync. I don't consider the last part very clean, though.

One more solution with resolving by name:

@Resource(name="country")

It uses javax.annotation package, so it's not Spring specific, but Spring supports it.

The way you are doing it is indeed the recommended one (for Python 2.x).

The issue of whether the class is passed explicitly to super is a matter of style rather than functionality. Passing the class to super fits in with Python's philosophy of "explicit is better than implicit".

iPad Media Queries (All generations - including iPad mini)

Thanks to Apple's work in creating a consistent experience for users, and easy time for developers, all 5 different iPads (iPads 1-5 and iPad mini) can be targeted with just one CSS media query. The next few lines of code should work perfect for a responsive design.

iPad in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px)  { /* STYLES GO HERE */}

iPad in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape) { /* STYLES GO HERE */}

iPad in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait) { /* STYLES GO HERE */ }

iPad 3 & 4 Media Queries

If you're looking to target only 3rd and 4th generation Retina iPads (or tablets with similar resolution) to add @2x graphics, or other features for the tablet's Retina display, use the following media queries.

Retina iPad in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */}

Retina iPad in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */}

Retina iPad in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */ }

iPad 1 & 2 Media Queries

If you're looking to supply different graphics or choose different typography for the lower resolution iPad display, the media queries below will work like a charm in your responsive design!

iPad 1 & 2 in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (-webkit-min-device-pixel-ratio: 1){ /* STYLES GO HERE */}

iPad 1 & 2 in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape)
and (-webkit-min-device-pixel-ratio: 1)  { /* STYLES GO HERE */}

iPad 1 & 2 in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait) 
and (-webkit-min-device-pixel-ratio: 1) { /* STYLES GO HERE */ }

I have the same problem. I changed the mac. And when I downloaded the Xcode certificate, I received an error message: "The error is that the security profile does not include the certificate signature."

1) Go to https://developer.apple.com/account/ios/profile/limited/edit Select the project => edit => Certificates => Select All => Create => Download

2) In Xcode: Project file => Signing (Debug) => Provisioning profile => Import profile => Select file with 1

There's a configuration variable within the phpMyAdmin directory that you can find in libraries\config.default.php called $cfg['ExecTimeLimit'] that you can set to whatever maximum execution time you need.

try this:

#/usr/bin/env python
import os, sys, atexit

try:
    # Set PID file
    def set_pid_file():
        pid = str(os.getpid())
        f = open('myCode.pid', 'w')
        f.write(pid)
        f.close()

    def goodby():
        pid = str('myCode.pid')
        os.remove(pid)

    atexit.register(goodby)
    set_pid_file()
    # Place your code here

except KeyboardInterrupt:
    sys.exit(0)

You should put this line in your application context:

<context:component-scan base-package="com.cinebot.service" />

Read more about Automatically detecting classes and registering bean definitions in documentation.

You can try jQuery treegrid (http://maxazan.github.io/jquery-treegrid/) or jQuery treetable (http://ludo.cubicphuse.nl/jquery-treetable/)

Both are using HTML <table> tag format and styled the as tree.

The jQuery treetable is using data-tt-id and data-tt-parent-id for determining the parent and child of the tree. Usage example:

<table id="tree">
  <tr data-tt-id="1">
    <td>Parent</td>
  </tr>
  <tr data-tt-id="2" data-tt-parent-id="1">
    <td>Child</td>
  </tr>
</table>
$("#tree").treetable({ expandable: true });

Meanwhile, jQuery treegrid is using only class for styling the tree. Usage example:

<table class="tree">
    <tr class="treegrid-1">
        <td>Root node</td><td>Additional info</td>
    </tr>
    <tr class="treegrid-2 treegrid-parent-1">
        <td>Node 1-1</td><td>Additional info</td>
    </tr>
    <tr class="treegrid-3 treegrid-parent-1">
        <td>Node 1-2</td><td>Additional info</td>
    </tr>
    <tr class="treegrid-4 treegrid-parent-3">
        <td>Node 1-2-1</td><td>Additional info</td>
    </tr>
</table>
<script type="text/javascript">
  $('.tree').treegrid();
</script>

There can be corrupted jar file for which it may show error as "ZipFile invalid LOC header (bad signature)" You need to delete all jar files for which it shows the error and add this Dependency

If none of above stated works then check for your device date, make sure your device date doesn't exceed profile expiry date i.e. not set to far future.

\S matches anything but a whitespace, according to this reference.

Not a one liner but very simple:

buffer = ""
some_str = "aas30dsa20"

for char in some_str:
    if not char.isdigit():
        buffer += char

print( buffer )

To make the answer simple here is a program that reads integers from the file and sorting them

f = open("input.txt", 'r')

nums = f.readlines()
nums = [int(i) for i in nums]

After reading each line of the file converting each string to a digit

nums.sort()

Sorting the numbers

f.close()

f = open("input.txt", 'w')
for num in nums:
    f.write("%d\n" %num)

f.close()

Writing them back As easy as that, Hope this helps

Easiest and Simplest method of solving this problem is using re

import re

search_list = ['one', 'two', 'there']
long_string = 'some one long two phrase three'
if re.compile('|'.join(search_list),re.IGNORECASE).search(long_string): #re.IGNORECASE is used to ignore case
    # Do Something if word is present
else:
    # Do Something else if word is not present

I've always used this syntax, which yields more predictable results than using !=.

<xsl:when test="not($AccountNumber = '12345') and not($Balance = '0')" />

Assuming your DataSource is of type DataTable, you can just do this:

myGridView.DataSource as DataTable

IN MAGENTO query in the database and fetch the result like. product id, product name and manufracturer with out using the product flat table use the eav catalog_product_entity and its attribute table product_id product_name manufacturer 1 | PRODUCTA | NOKIA 2 | PRODUCTB | SAMSUNG

instead of

self.theTable.tableFooterView = tableFooter;

try

[self.theTable.tableFooterView addSubview:tableFooter];

When you create a new File, you are supposed to provide the file name, not only the directory you want to put your file in.

Try with something like

File file = new File("D:/Data/" + item.getFileName());

I think the problem is that you are using type="text" instead of textarea. What you want is:

<textarea class="span6" rows="3" placeholder="What's up?" required></textarea>

To clarify, a type="text" will always be one row, where-as a textarea can be multiple.

If you are using tcsh, then edit your ~/.cshrc file to include the lines:

setenv CLICOLOR 1
setenv LSCOLORS dxfxcxdxbxegedabagacad

Where, like Martin says, LSCOLORS specifies the color scheme you want to use.

To generate the LSCOLORS you want to use, checkout this site

You could try my Beavertail ADSI browser - it should show you the current AD tree, and from it, you should be able to figure out the path and all.

Or if you're on .NET 3.5, using the System.DirectoryServices.AccountManagement namespace, you could also do it programmatically:

PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

This would create a basic, default domain context and you should be able to peek at its properties and find a lot of stuff from it.

Or:

UserPrincipal myself = UserPrincipal.Current;

This will give you a UserPrincipal object for yourself, again, with a ton of properties to inspect. I'm not 100% sure what you're looking for - but you most likely will be able to find it on the context or the user principal somewhere!

This is what I use to collect single frames, but if you modify this and keep the two targets open all the time then you could "stream" it to disk using a static counter for the file name. - I can't recall where I found this, but it has been modified, thanks to whoever!

   hr = Device->GetRenderTargetData(pRenderTarget, pDestTarget);
   //save its contents to a bitmap file.
   hr = D3DXSaveSurfaceToFile(file,

                              NULL);

   // clean up.
   pRenderTarget->Release();
   pDestTarget->Release();
}

In my current config I have it defined in application.yaml like that:

logging:
  level:
    ROOT: TRACE

I am using spring-boot:2.2.0.RELEASE. You can define any package which should have the TRACE level like that.

Delete existing adbkeys

OR

Rename adbkeys

Best practise is to rename the keys because it provides backup.

cd ~/.Android

mv adbkey adbkey2

mv adbkey.pub adbkey.pub2

Next stop & start the server

cd ~/Android/Sdk/platform-tools

Locate the device /Android/Sdk/platform-tools$ ./adb devices

/Android/Sdk/platform-tools$ ./adb kill-server

/Android/Sdk/platform-tools$ ./adb start-server

Then, stop the emulator Open AVD manager, click on the down arrow, then click on wipe data

Restart the emulator. Then everything works fine :)

Simply try removing the ".xib" from the nib name in "initWithNibName:". According to the documentation, the ".xib" is assumed and shouldn't be used.

Add a float to dimens.xml:

<item format="float" name="my_dimen" type="dimen">1.2</item>

To reference from XML:

<EditText 
    android:lineSpacingMultiplier="@dimen/my_dimen"
    ...

To read this value programmatically you can use ResourcesCompat.getFloat from androidx.core

Gradle dependency:

implementation("androidx.core:core:${version}")

Usage:

import androidx.core.content.res.ResourcesCompat;

...

float value = ResourcesCompat.getFloat(context.getResources(), R.dimen.my_dimen);

I had the same issue on my windows 10. This is what fixed my problem

1. Delete bower_components in your root folder
2. Create a .bowerrc file in the root
3. In the file write this code {"directory" : "public/bower_components"}
4. Run a bower install

You should see bower_components folder in your public folder now

Collection initializers are only available in VB.NET 2010, released 2010-04-12:

Dim theVar = New List(Of String) From { "one", "two", "three" }

I know the answer is already given but I want give a bit brief answer how to update value of a form so that other new comers can get a clear idea.

your form structure is so perfect to use it as an example. so, throughout my answer I will denote it as the form.

this.form = this.fb.group({
    'name': ['', Validators.required],
    'dept': ['', Validators.required],
    'description': ['', Validators.required]
  });

so our form is a FormGroup type of object that has three FormControl.

There are two ways to update the model value:

• Use the setValue() method to set a new value for an individual control. The setValue() method strictly adheres to the structure of the form group and replaces the entire value for the control.

• Use the patchValue() method to replace any properties defined in the object that have changed in the form model.

The strict checks of the setValue() method help catch nesting errors in complex forms, while patchValue() fails silently on those errors.

From Angular official documentation here

so, When updating the value for a form group instance that contains multiple controls, but you may only want to update parts of the model. patchValue() is the one you are looking for.

lets see example. When you use patchValue()

this.form.patchValue({
    dept: 1 
});
//here we are just updating only dept field and it will work.

but when you use setValue() you need to update the full model as it strictly adheres the structure of the form group. so, if we write

this.form.setValue({
    dept: 1 
});
// it will throw error.

We must pass all the properties of the form group model. like this

this.form.setValue({
      name: 'Mr. Bean'
      dept: 1,
      description: 'spome description'
  });

but I don't use this style frequently. I prefer using the following approach that helps to keep my code cleaner and more understandable.

What I do is, I declare all the controls as a seperate variable and use setValue() to update that specific control.

for the above form, I will do something like this.

get companyIdentifier(): FormControl {
    return this.form.get('name') as FormControl;
}

get dept(): FormControl {
    return this.form.get('dept') as FormControl;
}

get description(): FormControl {
    return this.form.get('description') as FormControl;
}

when you need to update the form control just use that property to update it. In the example the questioner tried to update the dept form control when user select an item from the drop down list.

deptSelected(selected: { id: string; text: string }) {
  console.log(selected) // Shows proper selection!

  // instead of using this.form.controls['dept'].setValue(selected.id), I prefer the following.

  this.dept.setValue(selected.id); // this.dept is the property that returns the 'dept' FormControl of the form.
}

I suggest to have a look FormGroup API to get know how of all the properties and methods of FormGroup.

Additional: to know about getter see here

This would work as well:

df = pd.DataFrame()
new_line = pd.Series({'A2M': 4.059, 'A2ML1': 4.28}, name='HCC1419')
df = df.append(new_line, ignore_index=False)

The name in the Series will be the index in the dataframe. ignore_index=False is the important flag in this case.

Use ifelse:

frame$twohouses <- ifelse(frame$data>=2, 2, 1)
frame
   data twohouses
1     0         1
2     1         1
3     2         2
4     3         2
5     4         2
...
16    0         1
17    2         2
18    1         1
19    2         2
20    0         1
21    4         2

The difference between if and ifelse:

• if is a control flow statement, taking a single logical value as an argument
• ifelse is a vectorised function, taking vectors as all its arguments.

The help page for if, accessible via ?"if" will also point you to ?ifelse

I also made a solution, which is working with Stacks. It's a more modular approach so u don't have to specify each Fragment and Detail Fragment in your FragmentPagerAdapter. It's build on top of the Example from ActionbarSherlock which derives if I'm right from the Google Demo App.

Add this for back button functionality in your MainActivity:

@Override
public void onBackPressed() {
  if (!mTabsAdapter.back(getSupportFragmentManager())) {
    super.onBackPressed();
  }
}

If u like to save the Fragment State when it get's removed. Let your Fragment implement the interface SaveStateBundle return in the function a bundle with your save state. Get the bundle after instantiation by this.getArguments().

You can instantiate a tab like this:

mTabsAdapter.addTab(mTabHost.newTabSpec("firstTabTag").setIndicator("First Tab Title"),
                FirstFragmentActivity.FirstFragmentFragment.class, null);

works similiar if u want to add a Fragment on top of a Tab Stack. Important: I think, it won't work if u want to have 2 instances of same class on top of two Tabs. I did this solution quick together, so I can only share it without providing any experience with it.

You can use upstream headers (named starting with $http_) and additional custom headers. For example:

add_header X-Upstream-01 $http_x_upstream_01;
add_header X-Hdr-01  txt01;

next, go to console and make request with user's header:

curl -H "X-Upstream-01: HEADER1" -I http://localhost:11443/

the response contains X-Hdr-01, seted by server and X-Upstream-01, seted by client:

HTTP/1.1 200 OK
Server: nginx/1.8.0
Date: Mon, 30 Nov 2015 23:54:30 GMT
Content-Type: text/html;charset=UTF-8
Connection: keep-alive
X-Hdr-01: txt01
X-Upstream-01: HEADER1

Use par(las=1).

See ?par:

las
numeric in {0,1,2,3}; the style of axis labels.
0: always parallel to the axis [default],
1: always horizontal,
2: always perpendicular to the axis,
3: always vertical.

To fix this bug, I did:

1. In php.ini file, uncomment this line: extension=php_curl.dll
2. In php.ini file, uncomment this line: extension_dir = "ext"
3. I restarted NETBEANS, as I was using Built-in server

There are no events in JQuery to detect css changes.
Refer here: onHide() type event in jQuery
It is possible:

DOM L2 Events module defines mutation events; one of them - DOMAttrModified is the one you need. Granted, these are not widely implemented, but are supported in at least Gecko and Opera browsers.
Source: Event detect when css property changed using Jquery

Without events, you can use setInterval function, like this:

var maxTime = 5000, // 5 seconds
    startTime = Date.now();

var interval = setInterval(function () {
        if ($('#element').is(':visible')) {
            // visible, do something
            clearInterval(interval);
        } else {
            // still hidden
            if (Date.now() - startTime > maxTime) {
                // hidden even after 'maxTime'. stop checking.
                clearInterval(interval);
            }
        }
    },
    100 // 0.1 second (wait time between checks)
);

Note that using setInterval this way, for keeping a watch, may affect your page's performance.

7th July 2018:
Since this answer is getting some visibility and up-votes recently, here is additional update on detecting css changes:

Mutation Events have been now replaced by the more performance friendly Mutation Observer.

The MutationObserver interface provides the ability to watch for changes being made to the DOM tree. It is designed as a replacement for the older Mutation Events feature which was part of the DOM3 Events specification.

Refer: https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver

just like below:

var img = new Image(); 
img.src = imgUrl; 

if (!img.complete) {

//has picture
}
else //not{ 

}

There is also another way of getting thread id. While creating threads with

int pthread_create(pthread_t * thread, const pthread_attr_t * attr, void * (*start_routine)(void *), void *arg);

function call; the first parameter pthread_t * thread is actually a thread id (that is an unsigned long int defined in bits/pthreadtypes.h). Also, the last argument void *arg is the argument that is passed to void * (*start_routine) function to be threaded.

You can create a structure to pass multiple arguments and send a pointer to a structure.

typedef struct thread_info {
    pthread_t thread;
    //...
} thread_info;
//...
tinfo = malloc(sizeof(thread_info) * NUMBER_OF_THREADS);
//...
pthread_create (&tinfo[i].thread, NULL, handler, (void*)&tinfo[i]);
//...
void *handler(void *targs) {
    thread_info *tinfo = targs;
    // here you get the thread id with tinfo->thread
}

Use Activtiy Context

Replace this

  final EditText input = new EditText(this);

By

  final EditText input = new EditText(MainActivity.this);  
  LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
                        LinearLayout.LayoutParams.MATCH_PARENT,
                        LinearLayout.LayoutParams.MATCH_PARENT);
  input.setLayoutParams(lp);
  alertDialog.setView(input); // uncomment this line

Sysinternals has another tool you could use, Strings.exe

Example:

strings.exe c:\windows\system32\wuauclt.exe > %temp%\wuauclt_strings.txt && %temp%\wuauclt_strings.txt

This was my solution using a directive which seems more Angular-y because we're dealing with the DOM:

Plnkr over here

github

CODE

angular.module('app', [])
.directive('scrollTo', function ($location, $anchorScroll) {
  return function(scope, element, attrs) {

    element.bind('click', function(event) {
        event.stopPropagation();
        var off = scope.$on('$locationChangeStart', function(ev) {
            off();
            ev.preventDefault();
        });
        var location = attrs.scrollTo;
        $location.hash(location);
        $anchorScroll();
    });

  };
});

I used the $anchorScroll service. To counteract the page-refresh that goes along with the hash changing I went ahead and cancelled the locationChangeStart event. This worked for me because I had a help page hooked up to an ng-switch and the refreshes would esentially break the app.

To answer the exact question:

      }

I know this is an old post, but I found it through Google, and after playing with it think I have an easier solution. If I'm wrong please point it out, 'cuz I'd like to know, but this worked for my purposes at least (It's based off of ICR's response):

for (int x = 0; x < array.GetLength(0); x++)
{
    Console.Write(array[x, 0], array[x,1], array[x,2]);
}

Since the both dimensions are limited, either one can be simple numbers, and thus avoid a nested for loop. I admit I'm new to C#, so please, if there's a reason not to do it, please tell me...

A good but "heavyweight" solution is to use Twisted - see the bottom.

If you're willing to live with only stdout something along those lines should work:

import subprocess
import sys
popenobj = subprocess.Popen(["ls", "-Rl"], stdout=subprocess.PIPE)
while not popenobj.poll():
   stdoutdata = popenobj.stdout.readline()
   if stdoutdata:
      sys.stdout.write(stdoutdata)
   else:
      break
print "Return code", popenobj.returncode

(If you use read() it tries to read the entire "file" which isn't useful, what we really could use here is something that reads all the data that's in the pipe right now)

One might also try to approach this with threading, e.g.:

import subprocess
import sys
import threading

popenobj = subprocess.Popen("ls", stdout=subprocess.PIPE, shell=True)

def stdoutprocess(o):
   while True:
      stdoutdata = o.stdout.readline()
      if stdoutdata:
         sys.stdout.write(stdoutdata)
      else:
         break

t = threading.Thread(target=stdoutprocess, args=(popenobj,))
t.start()
popenobj.wait()
t.join()
print "Return code", popenobj.returncode

Now we could potentially add stderr as well by having two threads.

Note however the subprocess docs discourage using these files directly and recommends to use communicate() (mostly concerned with deadlocks which I think isn't an issue above) and the solutions are a little klunky so it really seems like the subprocess module isn't quite up to the job (also see: http://www.python.org/dev/peps/pep-3145/ ) and we need to look at something else.

A more involved solution is to use Twisted as shown here: https://twistedmatrix.com/documents/11.1.0/core/howto/process.html

The way you do this with Twisted is to create your process using reactor.spawnprocess() and providing a ProcessProtocol that then processes output asynchronously. The Twisted sample Python code is here: https://twistedmatrix.com/documents/11.1.0/core/howto/listings/process/process.py

Line width in ggplot2 can be changed with argument size= in geom_line().

#sample data
df<-data.frame(x=rnorm(100),y=rnorm(100))
ggplot(df,aes(x=x,y=y))+geom_line(size=2)

How can I use the binary operator alongside the date filter?

<span class="gallery-date">{{gallery.date | date:'mediumDate' || "Date Empty"}}</span>

you also try:

<span class="gallery-date">{{ gallery.date == 'NULL' ? 'mediumDate' : "gallery.date"}}</span>

void WinErrorCodeToString(DWORD ErrorCode, string& Message)
{
char* locbuffer = NULL;
DWORD count = FormatMessageA(FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_ALLOCATE_BUFFER, NULL, ErrorCode,
    0, (LPSTR)&locbuffer, 0, nullptr);
if (locbuffer)
{
    if (count)
    {
        int c;
        int back = 0;
        //
        // strip any trailing "\r\n"s and replace by a single "\n"
        //
        while (((c = *CharPrevA(locbuffer, locbuffer + count)) == '\r') ||
            (c == '\n')) {
            count--;
            back++;
        }

        if (back) {
            locbuffer[count++] = '\n';
            locbuffer[count] = '\0';
        }

        Message = "Error: ";
        Message += locbuffer;
    }
    LocalFree(locbuffer);
}
else
{
    Message = "Unknown error code: " + to_string(ErrorCode);
}
}

For me the .crash file was enough. Without .dSYM file and .app file.

I ran these two commands on the mac where I build the archive and it worked:

export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer" 

/Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash  /yourPath/crash1.crash > /yourPath/crash1_symbolicated.crash

In your example, it’s fine as it is: it’s simple and works. The only things I’d suggest are:

1. validating the data POSTed

2. make sure your API is sending the Content-Type header to tell the client to expect a JSON response:

   header('Content-Type: application/json');
   echo json_encode($response);
   

Other than that, an API is something that takes an input and provides an output. It’s possible to “over-engineer” things, in that you make things more complicated that need be.

If you wanted to go down the route of controllers and models, then read up on the MVC pattern and work out how your domain objects fit into it. Looking at the above example, I can see maybe a MathController with an add() action/method.

There are a few starting point projects for RESTful APIs on GitHub that are worth a look.

Suppose your data looks like this:

import pandas as pd
import numpy as np

np.random.seed(2015)
df = pd.DataFrame([])
for i in range(5):
    data = dict(zip(np.random.choice(10, replace=False, size=5),
                    np.random.randint(10, size=5)))
    data = pd.DataFrame(data.items())
    data = data.transpose()
    data.columns = data.iloc[0]
    data = data.drop(data.index[[0]])
    df = df.append(data)
print('{}\n'.format(df))
# 0   0   1   2   3   4   5   6   7   8   9
# 1   6 NaN NaN   8   5 NaN NaN   7   0 NaN
# 1 NaN   9   6 NaN   2 NaN   1 NaN NaN   2
# 1 NaN   2   2   1   2 NaN   1 NaN NaN NaN
# 1   6 NaN   6 NaN   4   4   0 NaN NaN NaN
# 1 NaN   9 NaN   9 NaN   7   1   9 NaN NaN

Then it could be replaced with

np.random.seed(2015)
data = []
for i in range(5):
    data.append(dict(zip(np.random.choice(10, replace=False, size=5),
                         np.random.randint(10, size=5))))
df = pd.DataFrame(data)
print(df)

In other words, do not form a new DataFrame for each row. Instead, collect all the data in a list of dicts, and then call df = pd.DataFrame(data) once at the end, outside the loop.

Each call to df.append requires allocating space for a new DataFrame with one extra row, copying all the data from the original DataFrame into the new DataFrame, and then copying data into the new row. All that allocation and copying makes calling df.append in a loop very inefficient. The time cost of copying grows quadratically with the number of rows. Not only is the call-DataFrame-once code easier to write, it's performance will be much better -- the time cost of copying grows linearly with the number of rows.

You want to change the I am working in ABC company. to I am working in ABC company.. These are the same strings, so I don't see a reason to, but you can accomplish this by using the JavaScript innerHTML or textContent.

element.innerHTML is a property that defines the HTML inside an element. If you type element.innerHTML = "<strong>This is bold</strong>, it'll make the text "This is bold" bold text.

element.textContent, on the other hand, sets the text in an element. If you use element.textContent = "<strong>This is bold</strong>, The text "This is bold" will not be bold. The user will literally see the text "This is bold

In your case, you can use either one. I'll use .textContent. The code to change the <p> element is below.

function get_content(){
   document.getElementById("txt").textContent = "I am working in ABC company.";
}

<input type="button" onclick="get_content()" value="Get Content"/>
<p id='txt'>
<span class="A">I am</span>
<span class="B">working in </span>
<span class="C">ABC company.</span>
</p>

This, unfortunately, will not change it because it'll change it to the same exact text. You can chance that by changing the string "I am working in ABC company." to something else.

run the below code in Terminal

makesure You are inside your project folder in terminal

ng g s servicename --module=app.module

You can use playbook_dir variable.

At first glance...

All you need is a GROUP BY clause with the MAX aggregate function:

SELECT id, MAX(rev)
FROM YourTable
GROUP BY id

It's never that simple, is it?

I just noticed you need the content column as well.

This is a very common question in SQL: find the whole data for the row with some max value in a column per some group identifier. I heard that a lot during my career. Actually, it was one the questions I answered in my current job's technical interview.

It is, actually, so common that StackOverflow community has created a single tag just to deal with questions like that: greatest-n-per-group.

Basically, you have two approaches to solve that problem:

Joining with simple group-identifier, max-value-in-group Sub-query

In this approach, you first find the group-identifier, max-value-in-group (already solved above) in a sub-query. Then you join your table to the sub-query with equality on both group-identifier and max-value-in-group:

SELECT a.id, a.rev, a.contents
FROM YourTable a
INNER JOIN (
    SELECT id, MAX(rev) rev
    FROM YourTable
    GROUP BY id
) b ON a.id = b.id AND a.rev = b.rev

Left Joining with self, tweaking join conditions and filters

In this approach, you left join the table with itself. Equality goes in the group-identifier. Then, 2 smart moves:

1. The second join condition is having left side value less than right value
2. When you do step 1, the row(s) that actually have the max value will have NULL in the right side (it's a LEFT JOIN, remember?). Then, we filter the joined result, showing only the rows where the right side is NULL.

So you end up with:

SELECT a.*
FROM YourTable a
LEFT OUTER JOIN YourTable b
    ON a.id = b.id AND a.rev < b.rev
WHERE b.id IS NULL;

Conclusion

Both approaches bring the exact same result.

If you have two rows with max-value-in-group for group-identifier, both rows will be in the result in both approaches.

Both approaches are SQL ANSI compatible, thus, will work with your favorite RDBMS, regardless of its "flavor".

Both approaches are also performance friendly, however your mileage may vary (RDBMS, DB Structure, Indexes, etc.). So when you pick one approach over the other, benchmark. And make sure you pick the one which make most of sense to you.

When you define a server in server view, then it will create you a server runtime library with server libs (including servlet api), that can be assigned to your project. However, then everybody that uses your project, need to create the same type of runtime in his/her eclipse workspace even for compiling.

If you directly download the servlet api jar, than it could lead to problems, since it will be included into the artifacts of your projects, but will be also present in servlet container.

In Maven it is much nicer, since you can define the servlet api interfaces as a "provided" dependency, that means it is present in the "to be production" environment.

To avoid the error, use extract string:

<string name="travels_tours_pvt_ltd"><![CDATA[Travels & Tours (Pvt) Ltd.]]></string>

With my experiance the best open source option will be UIKIT with its uikit slider component. and it is very easy to implement for example in your case you could do something like this.

<div data-uk-slider>
<div class="uk-slider-container">
    <ul class="uk-slider uk-grid-width-medium-1-4"> // width of the elements
        <li>...</li> //slide elements
        ...
    </ul>
</div>

No need to embed! Just simply send the user to google and add the var in the search like this: (Remember, code might not work on this, so try in a browser if it doesn't.) Hope it works!

<textarea id="Blah"></textarea><button onclick="search()">Search</button>
<script>
function search() {
var Blah = document.getElementById("Blah").value;
location.replace("https://www.google.com/search?q=" + Blah + "");
}
</script>

    function search() {_x000D_
    var Blah = document.getElementById("Blah").value;_x000D_
    location.replace("https://www.google.com/search?q=" + Blah + "");_x000D_
    }

<textarea id="Blah"></textarea><button onclick="search()">Search</button>

As of right now, GCC has much better and more complete support for C++11 features than Clang. Also, the code generator for GCC performs better optimisation than the one in Clang (in my experience, I have not seen any exhaustive tests).

On the other hand, Clang often compiles code more quickly than GCC, and produces better error messages when there is something wrong with your code.

The choice of which one to use really depends on what things are important to you. I value C++11 support and code generation quality more than I value convenience of compilation. Because of this, I use GCC. For you, the trade-offs could be different.

You can get path by this code

Dim CurDir as string = My.Application.Info.DirectoryPath

Edit: I ended up prototyping out the concept on GitHub. Check out: https://github.com/sivabudh/system-in-a-box

First, my answer is geared towards 2 groups of people: those who use a Mac, and those who use Linux.

The host network mode doesn't work on a Mac. You have to use an IP alias, see: https://stackoverflow.com/a/43541681/2713729

What is a host network mode? See: https://docs.docker.com/engine/reference/run/#/network-settings

Secondly, for those of you who are using Linux (my direct experience was with Ubuntu 14.04 LTS and I'm upgrading to 16.04 LTS in production soon), yes, you can make the service running inside a Docker container connect to localhost services running on the Docker host (eg. your laptop).

How?

The key is when you run the Docker container, you have to run it with the host mode. The command looks like this:

docker run --network="host" -id <Docker image ID>

When you do an ifconfig (you will need to apt-get install net-tools your container for ifconfig to be callable) inside your container, you will see that the network interfaces are the same as the one on Docker host (eg. your laptop).

It's important to note that I'm a Mac user, but I run Ubuntu under Parallels, so using a Mac is not a disadvantage. ;-)

And this is how you connect NGINX container to the MySQL running on a localhost.

Place right_ax before set_ylabel()

ax.right_ax.set_ylabel('AB scale')

I realize that the question was asked some time ago, but I thought it might help some people, who are googling around (like me), and hit this page.

Scallop looks quite promising as well.

Features (quote from the linked github page):

• flag, single-value and multiple value options
• POSIX-style short option names (-a) with grouping (-abc)
• GNU-style long option names (--opt)
• Property arguments (-Dkey=value, -D key1=value key2=value)
• Non-string types of options and properties values (with extendable converters)
• Powerful matching on trailing args
• Subcommands

And some example code (also from that Github page):

import org.rogach.scallop._;

object Conf extends ScallopConf(List("-c","3","-E","fruit=apple","7.2")) {
  // all options that are applicable to builder (like description, default, etc) 
  // are applicable here as well
  val count:ScallopOption[Int] = opt[Int]("count", descr = "count the trees", required = true)
                .map(1+) // also here work all standard Option methods -
                         // evaluation is deferred to after option construction
  val properties = props[String]('E')
  // types (:ScallopOption[Double]) can be omitted, here just for clarity
  val size:ScallopOption[Double] = trailArg[Double](required = false)
}


// that's it. Completely type-safe and convenient.
Conf.count() should equal (4)
Conf.properties("fruit") should equal (Some("apple"))
Conf.size.get should equal (Some(7.2))
// passing into other functions
def someInternalFunc(conf:Conf.type) {
  conf.count() should equal (4)
}
someInternalFunc(Conf)

might be surprised to know.. its PHP. read all about it here

An old thread, nonetheless someone may benefit from this:

li:not(:last-child)::after { content: ","; }
li:last-child::after { content: "."; }

This should work in CSS3 and [untested] CSS2.

This happened to me yesterday and in my case was because I was following a PDF manual to develop some module to communicate with an API and while copying the link directly from the manual, for some odd reason, the hyphen from the copied link was in a different encoding and hence the curl_exec() was always returning false because it was unable to communicate with the server.

It took me a couple hours to finally understand the diference in the characters bellow:

https://www.e-example.com/api
https://www.e-example.com/api

Every time I tried to access the link directly from a browser it converted to something likehttps://www.xn--eexample-0m3d.com/api.

It may seem to you that they are equal but if you check the encoding of the hyphens here you'll see that the first hyphen is a unicode characters U+2010 and the other is a U+002D.

Hope this helps someone.

Isn't the platform solution for this implementation to use a context menu that shows on a long press?

Is the question author aware of context menus? Stacking up buttons in a listview has performance implications, will clutter your UI and violate the recommended UI design for the platform.

On the flipside; context menus - by nature of not having a passive representation - are not obvious to the end user. Consider documenting the behaviour?

This guide should give you a good start.

If you are getting back a sun.awt.image.ToolkitImage, you can cast the Image to that, and then use getBufferedImage() to get the BufferedImage.

So instead of your last line of code where you are casting you would just do:

BufferedImage buffered = ((ToolkitImage) image).getBufferedImage();

To expand Hitesh's answer if you want to drop rows where 'x' specifically is nan, you can use the subset parameter. His answer will drop rows where other columns have nans as well

dat.dropna(subset=['x'])

You could use cut

 df$valueBin <- cut(df$value, c(-Inf, 250, 500, 1000, 2000, Inf), 
    labels=c('<=250', '250-500', '500-1,000', '1,000-2,000', '>2,000'))

data

 set.seed(24)
 df <- data.frame(value= sample(0:2500, 100, replace=TRUE))

That's one solution. If you add it to your .bashrc, it'll display the current branch in the console.

# git branch
parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1) /'
}
$PS1="\$(parse_git_branch)$PS1"

However it's pretty limited. But there is a great project called git sh, which is doing exactly that (and much more).

This can be done using CSS3 columns quite easily. Here's an example, HTML:

#limheight {_x000D_
    height: 300px; /*your fixed height*/_x000D_
    -webkit-column-count: 3;_x000D_
       -moz-column-count: 3;_x000D_
            column-count: 3; /*3 in those rules is just placeholder -- can be anything*/_x000D_
}_x000D_
_x000D_
#limheight li {_x000D_
    display: inline-block; /*necessary*/_x000D_
}

<ul id = "limheight">_x000D_
 <li><a href="">Glee is awesome 1</a></li>_x000D_

</ul>

I have two recommendation for you

1. Use CI Friendly Revision for all your artifacts. You can add -Drevision=2.0.1 in .mvn/maven.config file. So basically you define your version only at one location.
2. For all external dependency create a property in parent file. You can use Apache Camel Parent Pom as reference

Use:

ini_set('display_errors','off');

It is working fine in WordPress' config.php.

Just do System.out.println(e.getActionCommand()); inside actionPerformed(ActionEvent e) function. This will tell you which command is just performed.

or

if(e.getActionCommand().equals("Add")){

   System.out.println("Add button pressed");
}

Arrays.sort(yourList,new Comparator<YourObject>() {

    @Override
    public int compare(YourObjecto1, YourObjecto2) {
        return compare(o1.getYourColumn(), o2.getYourColumn());
    }
});

Try this set of code to download a CSV file from the server.

byte[] Content= File.ReadAllBytes(FilePath); //missing ;
Response.ContentType = "text/csv";
Response.AddHeader("content-disposition", "attachment; filename=" + fileName + ".csv");
Response.BufferOutput = true;
Response.OutputStream.Write(Content, 0, Content.Length);
Response.End();

It may be worth pointing out that ?s are only allowed in method names, not variables. In the process of learning Ruby, I assumed that ? designated a boolean return type so I tried adding them to flag variables, leading to errors. This led to me erroneously believing for a while that there was some special syntax involving ?s.

Relevant: Why can't a variable name end with `?` while a method name can?

The EntityManager.flush() operation can be used the write all changes to the database before the transaction is committed. By default JPA does not normally write changes to the database until the transaction is committed. This is normally desirable as it avoids database access, resources and locks until required. It also allows database writes to be ordered, and batched for optimal database access, and to maintain integrity constraints and avoid deadlocks. This means that when you call persist, merge, or remove the database DML INSERT, UPDATE, DELETE is not executed, until commit, or until a flush is triggered.

Try this out to execute a command on 30th March 2011 at midnight:

WARNING: As noted in comments, the year column is not supported in standard/default implementations of cron. Please refer to TomOnTime answer below, for a proper way to run a script at a specific time in the future in standard implementations of cron.

There's a little bit more information about the semantics of these errors in RFC 2616, which documents HTTP 1.1.

Personally, I would probably use 400 Bad Request, but this is just my personal opinion without any factual support.

For numerous reasons, No.

Why is explained in this MSDN post.

First, from a performance perspective the pointers get larger, so data structures get larger, and the processor cache stays the same size. That basically results in a raw speed hit (your mileage may vary). So you start in a hole and you have to dig yourself out of that hole by using the extra memory above 4G to your advantage. In Visual Studio this can happen in some large solutions but I think a preferable thing to do is to just use less memory in the first place. Many of VS’s algorithms are amenable to this. Here’s an old article that discusses the performance issues at some length: https://docs.microsoft.com/archive/blogs/joshwil/should-i-choose-to-take-advantage-of-64-bit

Secondly, from a cost perspective, probably the shortest path to porting Visual Studio to 64 bit is to port most of it to managed code incrementally and then port the rest. The cost of a full port of that much native code is going to be quite high and of course all known extensions would break and we’d basically have to create a 64 bit ecosystem pretty much like you do for drivers. Ouch.

You forget a '}' before the last line (to close the "methods {...").

Git doesn't think in terms of file versions. A version in git is a snapshot of the entire tree.

Given this, what you really want is a tree that has the latest content of most files, but with the contents of one file the same as it was 5 commits ago. This will take the form of a new commit on top of the old ones, and the latest version of the tree will have what you want.

I don't know if there's a one-liner that will revert a single file to the contents of 5 commits ago, but the lo-fi solution should work: checkout master~5, copy the file somewhere else, checkout master, copy the file back, then commit.

For structuring an app, this is one of the best guides that I've found:

• Google's Best Practice Recommendations for Angular App Structure

Note that the structure recommended by Google is different than what you'll find in a lot of seed projects, but for large apps it's a lot saner.

Google also has a style guide that makes sense to use only if you also use Closure.

...this answer is incomplete, but I hope that the limited information above will be helpful to someone.
