As stated in the above answers, it's always a good practice to initialize the variables, but if you have something which you don't know what value should it takes, and you want to leave it uninitialized so you have to make sure that you are updating it before using it.

For example: Assume we have double _bmi; and you don't know what value should it takes, so you can leave it as it is, but before using it, you have to update its value first like calling a function that calculating BMI like follows:

String calculateBMI (){
_bmi = weight / pow( height/100, 2);
return _bmi.toStringAsFixed(1);}

or whatever, what I mean is, you can leave the variable as it is, but before using it make sure you have initialized it using whatever the method you are using.

The problem is that you are using gulp 4 and the syntax in gulfile.js is of gulp 3. So either downgrade your gulp to 3.x.x or make use of gulp 4 syntaxes.

Syntax Gulp 3:

gulp.task('default', ['sass'], function() {....} );

Syntax Gulp 4:

gulp.task('default', gulp.series(sass), function() {....} );

We had this problem multiple times in the company I work at. Deleting the node_modules folder from the .nvm folder fixed the problem:

rm -rf ~/.nvm/versions/node/v8.6.0/lib/node_modules

This one works on Bootstrap 4.3.1.

The HTML code might be a little bit messy because I create a slightly complex dropdown menu for comprehensive test, otherwise everything is pretty straight forward.

Js includes fewer ways to collapse opened dropdowns and CSS only includes minimal styles for full functionalities.

For Anaconda users in Windows 10 and those who recently updated Anaconda environment, TensorFlow may cause some issues to activate or initiate. Here is the solution which I explored and which worked for me:

• Uninstall current Anaconda environment and delete all the existing files associated with Anaconda from your C:\Users or where ever you installed it.
• Download Anaconda (https://www.anaconda.com/download/?lang=en-us#windows)
• While installing, check the "Add Anaconda to my PATH environment variable"
• After installing, open the Anaconda command prompt to install TensorFlow using these steps:
• Create a conda environment named tensorflow by invoking the following command:

  conda create -n tensorflow python=3.5 (Use this command even if you are using python 3.6 because TensorFlow will get upgraded in the following steps)

• Activate the conda environment by issuing the following command:

  activate tensorflow After this step, the command prompt will change to (tensorflow)

• After activating, upgrade tensorflow using this command:

  pip install --ignore-installed --upgrade Now you have successfully installed the CPU version of TensorFlow.

• Close the Anaconda command prompt and open it again and activate the tensorflow environment using 'activate tensorflow' command.
• Inside the tensorflow environment, install the following libraries using the commands: pip install jupyter pip install keras pip install pandas pip install pandas-datareader pip install matplotlib pip install scipy pip install sklearn
• Now your tensorflow environment contains all the common libraries used in deep learning.
• Congrats, these libraries will make you ready to build deep neural nets. If you need more libraries install using the same command 'pip install libraryname'

The most voted answer covers most part but I would like to high light use case point of view. Can kafka do that rabbit mq can do, answer is yes but can rabbit mq do everything that kafka does, the answer is no.

The thing that rabbit mq cannot do that makes kafka apart, is distributed message processing. With this now read back the most voted answer and it will make more sense.

To elaborate, take a use case where you need to create a messaging system that has super high throughput for example "likes" in facebook and You have chosen rabbit mq for that. You created an exchange and queue and a consumer where all publishers (in this case FB users) can publish 'likes' messages. Since your throughput is high, you will create multiple threads in consumer to process messages in parallel but you still bounded by the hardware capacity of the machine where consumer is running. Assuming that one consumer is not sufficient to process all messages - what would you do?

• Can you add one more consumer to queue - no you cant do that.
• Can you create a new queue and bind that queue to exchange that publishes 'likes' message, answer is no cause you will have messages processed twice.

That is the core problem that kafka solves. It lets you create distributed partitions (Queue in rabbit mq) and distributed consumer that talk to each other. That ensures your messages in a topic get processed by consumers distributed in various nodes (Machines).

Kafka brokers ensure that messages get load balanced across all partitions of that topic. Consumer group make sure that all consumer talk to each other and message does not get processed twice.

But in real life you will not face this problem unless your throughput is seriously high because rabbit mq can also process data very fast even with one consumer.

In Bootstrap 4.3, col-xs-{value} is replaced by col-{value}

There is no change in sm, md, lg, xl remains the same.

.col-{value}
.col-sm-{value}
.col-md-{value}
.col-lg-{value}
.col-xl-{value}

If you want to access event object as well as data passed, you have to pass event and ticket.id both as parameters, like following:

HTML

<input type="number" v-on:input="addToCart($event, ticket.id)" min="0" placeholder="0">

Javascript

methods: {
  addToCart: function (event, id) {
    // use event here as well as id
    console.log('In addToCart')
    console.log(id)
  }
}

See working fiddle: https://jsfiddle.net/nee5nszL/

Edited: case with vue-router

In case you are using vue-router, you may have to use $event in your v-on:input method like following:

<input type="number" v-on:input="addToCart($event, num)" min="0" placeholder="0">

Here is working fiddle.

Even without looking at assembly, the most obvious reason is that /= 2 is probably optimized as >>=1 and many processors have a very quick shift operation. But even if a processor doesn't have a shift operation, the integer division is faster than floating point division.

Edit: your milage may vary on the "integer division is faster than floating point division" statement above. The comments below reveal that the modern processors have prioritized optimizing fp division over integer division. So if someone were looking for the most likely reason for the speedup which this thread's question asks about, then compiler optimizing /=2 as >>=1 would be the best 1st place to look.

On an unrelated note, if n is odd, the expression n*3+1 will always be even. So there is no need to check. You can change that branch to

{
   n = (n*3+1) >> 1;
   count += 2;
}

So the whole statement would then be

if (n & 1)
{
    n = (n*3 + 1) >> 1;
    count += 2;
}
else
{
    n >>= 1;
    ++count;
}

After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.

It's incorrect to use zeros in date or in datetime, just put null instead of zeros.

I have got this error (in MacBook) though I used correct command to create image,

docker build -t testimg .

Later I found that path is the problem. Just navigate to the correct path that contains docker file. Just double check your current working directory .Nothing to panic!

You can use sudo ip link delete to remove the interface.

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

Concrete example

mosquitto.org is very active (at the time of this posting). This is a nice smoke test for a MQTT subscriber linux device:

mosquitto_sub -h test.mosquitto.org -t "#" -v

The "#" is a wildcard for topics and returns all messages (topics): the server had a lot of traffic, so it returned a 'firehose' of messages.

If your MQTT device publishes a topic of irisys/V4D-19230005/ to the test MQTT broker , then you could filter the messages:

mosquitto_sub -h test.mosquitto.org -t "irisys/V4D-19230005/#" -v

Options:

• -h the hostname (default MQTT port = 1883)
• -t precedes the topic

There is a ready to use utility called "docker-wait" that can be used for waiting.

If you need permissions, you cannot use 'pip' with 'sudo'. You can do a trick, so that you can use 'sudo' and install package. Just place 'sudo python -m ...' in front of your pip command.

sudo python -m pip install --user -r package_name

Using Font Awesome 5, the markup is a bit more complex than the previouis answer. Per the FA documentation, the markup should be:

<ul class="fa-ul">
  <li><span class="fa-li"><i class="fas fa-check-square"></i></span>List icons can</li>
  <li><span class="fa-li"><i class="fas fa-check-square"></i></span>be used to</li>
  <li><span class="fa-li"><i class="fas fa-spinner fa-pulse"></i></span>replace bullets</li>
  <li><span class="fa-li"><i class="far fa-square"></i></span>in lists</li>
</ul>

I usually test the result of docker images -q (as in this script):

if [[ "$(docker images -q myimage:mytag 2> /dev/null)" == "" ]]; then
  # do something
fi

But since docker images only takes REPOSITORY as parameter, you would need to grep on tag, without using -q.

docker images takes tags now (docker 1.8+) [REPOSITORY[:TAG]]

The other approach mentioned below is to use docker inspect.
But with docker 17+, the syntax for images is: docker image inspect (on an non-existent image, the exit status will be non-0)

As noted by iTayb in the comments:

• The docker images -q method can get really slow on a machine with lots of images. It takes 44s to run on a 6,500 images machine.
• The docker image inspect returns immediately.

If you use tostring you lose information on both shape and data type:

>>> import numpy as np
>>> a = np.arange(12).reshape(3, 4)
>>> a
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])
>>> s = a.tostring()
>>> aa = np.fromstring(a)
>>> aa
array([  0.00000000e+000,   4.94065646e-324,   9.88131292e-324,
         1.48219694e-323,   1.97626258e-323,   2.47032823e-323,
         2.96439388e-323,   3.45845952e-323,   3.95252517e-323,
         4.44659081e-323,   4.94065646e-323,   5.43472210e-323])
>>> aa = np.fromstring(a, dtype=int)
>>> aa
array([ 0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11])
>>> aa = np.fromstring(a, dtype=int).reshape(3, 4)
>>> aa
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])

This means you have to send the metadata along with the data to the recipient. To exchange auto-consistent objects, try cPickle:

>>> import cPickle
>>> s = cPickle.dumps(a)
>>> cPickle.loads(s)
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])

"better" is relative. It all depends on what your needs are. Docker compose is for orchestrating multiple containers. If these images already exist in the docker registry, then it's better to list them in the compose file. If these images or some other images have to be built from files on your computer, then you can describe the processes of building those images in a Dockerfile.

I understand that Dockerfiles are used in Docker Compose, but I am not sure if it is good practice to put everything in one large Dockerfile with multiple FROM commands for the different images?

Using multiple FROM in a single dockerfile is not a very good idea because there is a proposal to remove the feature. 13026

If for instance, you want to dockerize an application which uses a database and have the application files on your computer, you can use a compose file together with a dockerfile as follows

docker-compose.yml

mysql:
  image: mysql:5.7
  volumes:
    - ./db-data:/var/lib/mysql
  environment:
    - "MYSQL_ROOT_PASSWORD=secret"
    - "MYSQL_DATABASE=homestead"
    - "MYSQL_USER=homestead"
  ports:
    - "3307:3306"
app:
  build:
    context: ./path/to/Dockerfile
    dockerfile: Dockerfile
  volumes:
    - ./:/app
  working_dir: /app
      

Dockerfile

FROM php:7.1-fpm 
RUN apt-get update && apt-get install -y libmcrypt-dev \
  mysql-client libmagickwand-dev --no-install-recommends \
  && pecl install imagick \
  && docker-php-ext-enable imagick \
  && docker-php-ext-install pdo_mysql \
  && curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

For me the solution was simple: the user name is case sensitive. Failing to use the correct caps will also lead to the error.

If you wish to have an GUI based broker testing without installing any tool you can use Hive Mqtt web socket for testing your Mosquitto server

just visit http://www.hivemq.com/demos/websocket-client/ and enter server connection details.

If you got connected means your server is configured properly.

You can also test publish and subscribe of messages using this mqtt web socket

For anyone else coming across this... I found the issue was caused by importing a custom framework, I have no idea how to correct it. But simply removing the import and any code referencing items from the framework fixes the issue.

(?°?°)?? ???

Hope this can save someone a few hours chasing down which line is causing the issue.

I ran into this issue when I changed the name of the variable which connected to one of my buttons. So keep that in mind!

Crazy idea...

You could play around with some pseudo elements, and create up/down arrows of css content hex codes. The only challange will be to precise the positioning of the arrow, but it may work:

input[type="number"] {_x000D_
    height: 100px;_x000D_
}_x000D_
_x000D_
.number-wrapper {_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
.number-wrapper:hover:after {_x000D_
    content: "\25B2";_x000D_
    position: absolute;_x000D_
    color: blue;_x000D_
    left: 100%;_x000D_
    margin-left: -17px;_x000D_
    margin-top: 12%;_x000D_
    font-size: 11px;_x000D_
}_x000D_
_x000D_
.number-wrapper:hover:before {_x000D_
    content: "\25BC";_x000D_
    position: absolute;_x000D_
    color: blue;_x000D_
    left: 100%;_x000D_
    bottom: 0;_x000D_
    margin-left: -17px;_x000D_
    margin-bottom: -14%;_x000D_
    font-size: 11px;_x000D_
}

<span class='number-wrapper'>_x000D_
    <input type="number" />_x000D_
</span>

2 steps solved my problem:

1) Delete "/Library/LaunchDaemons/com.mysql.mysql.plist"

2) Restart Yosemite

Another very similar answer is to use "equals" instead of "contains".

<li th:class="${#strings.equals(pageTitle,'How It Works')} ? active : ''">

I had the same issue in Flask and after trying the first 2 solutions which are the same (Authorization: Bearer <token>), and getting this:

{
    "description": "Unsupported authorization type",
    "error": "Invalid JWT header",
    "status_code": 401
}

I managed to finally solve it by using:

Authorization: jwt <token>

Thought it might save some time to people who encounter the same thing.

I was executing a get request an also want to see just the response and nothing else, seems like magic is done with -silent,-s option.

From the curl man page:

-s, --silent Silent or quiet mode. Don't show progress meter or error messages. Makes Curl mute. It will still output the data you ask for, potentially even to the terminal/stdout unless you redirect it.

Below the examples:

curl -s "http://host:8080/some/resource"
curl -silent "http://host:8080/some/resource"

Using custom headers

curl -s -H "Accept: application/json" "http://host:8080/some/resource")

Using POST method with a header

curl -s -X POST -H "Content-Type: application/json" "http://host:8080/some/resource") -d '{ "myBean": {"property": "value"}}'

You can also customize the output for specific values with -w, below the options I use to get just response codes of the curl:

curl -s -o /dev/null -w "%{http_code}" "http://host:8080/some/resource"

The official docker answer to Run multiple services in a container.

It explains how you can do it with an init system (systemd, sysvinit, upstart) , a script (CMD ./my_wrapper_script.sh) or a supervisor like supervisord.

The && workaround can work only for services that starts in background (daemons) or that will execute quickly without interaction and release the prompt. Doing this with an interactive service (that keeps the prompt) and only the first service will start.

To do this task download.js library can be used. Here is an example from library docs:

download("data:image/gif;base64,R0lGODlhRgAVAIcAAOfn5+/v7/f39////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////yH5BAAAAP8ALAAAAABGABUAAAj/AAEIHAgggMGDCAkSRMgwgEKBDRM+LBjRoEKDAjJq1GhxIMaNGzt6DAAypMORJTmeLKhxgMuXKiGSzPgSZsaVMwXUdBmTYsudKjHuBCoAIc2hMBnqRMqz6MGjTJ0KZcrz5EyqA276xJrVKlSkWqdGLQpxKVWyW8+iJcl1LVu1XttafTs2Lla3ZqNavAo37dm9X4eGFQtWKt+6T+8aDkxUqWKjeQUvfvw0MtHJcCtTJiwZsmLMiD9uplvY82jLNW9qzsy58WrWpDu/Lp0YNmPXrVMvRm3T6GneSX3bBt5VeOjDemfLFv1XOW7kncvKdZi7t/S7e2M3LkscLcvH3LF7HwSuVeZtjuPPe2d+GefPrD1RpnS6MGdJkebn4/+oMSAAOw==", "dlDataUrlBin.gif", "image/gif");

Something that just happened to me and caused me some headaches:

I have set up a new Linux RabbitMQ server and used a shell script to set up my own custom users (not guest!).

The script had several of those "code" blocks:

rabbitmqctl add_user test test
rabbitmqctl set_user_tags test administrator
rabbitmqctl set_permissions -p / test ".*" ".*" ".*"

Very similar to the one in Gabriele's answer, so I take his code and don't need to redact passwords.

Still I was not able to log in in the management console. Then I noticed that I had created the setup script in Windows (CR+LF line ending) and converted the file to Linux (LF only), then reran the setup script on my Linux server.

... and was still not able to log in, because it took another 15 minutes until I realized that calling add_user over and over again would not fix the broken passwords (which probably ended with a CR character). I had to call change_password for every user to fix my earlier mistake:

rabbitmqctl change_password test test

(Another solution would have been to delete all users and then call the script again)

Here's a fixed version of it: http://play.golang.org/p/w2ZcOzGHKR

The biggest fix that was needed is when Unmarshalling an array, that property needs to be an array/slice in the struct as well.

For example:

{ "things": ["a", "b", "c"] }

Would Unmarshal into a:

type Item struct {
    Things []string
}

And not into:

type Item struct {
    Things string
}

The other thing to watch out for when Unmarshaling is that the types line up exactly. It will fail when Unmarshalling a JSON string representation of a number into an int or float field -- "1" needs to Unmarshal into a string, not into an int like we saw with ShippingAdditionalCost int

Basically the default server usually run on the background at port 8080. Open services.msc and stop tomcat server and try running the spring boot application again.

I had the same problems. I had to change file rights. Unmark "read only" in their properties.

<form>
<input type="text" placeholder="user-name" /><br>
<input type=submit value="submit" id="submit" /> <br>
</form>

<script>
$(window).load(function() {
$('form').children('input:not(#submit)').val('')
}

</script>

You can use this script where every you want.

I know this is an older issue, but I recently had the same problem and was having issues resolving it, despite attempting the DisplayUnlockCaptcha fix. This is how I got it alive.

Head over to Account Security Settings (https://www.google.com/settings/security/lesssecureapps) and enable "Access for less secure apps", this allows you to use the google smtp for clients other than the official ones.

Update

Google has been so kind as to list all the potential problems and fixes for us. Although I recommend trying the less secure apps setting. Be sure you are applying these to the correct account.

• If you've turned on 2-Step Verification for your account, you might need to enter an App password instead of your regular password.
• Sign in to your account from the web version of Gmail at https://mail.google.com. Once you’re signed in, try signing in
  to the mail app again.
• Visit http://www.google.com/accounts/DisplayUnlockCaptcha and sign in with your Gmail username and password. If asked, enter the
  letters in the distorted picture.
• Your app might not support the latest security standards. Try changing a few settings to allow less secure apps access to your account.
• Make sure your mail app isn't set to check for new email too often. If your mail app checks for new messages more than once every 10
  minutes, the app’s access to your account could be blocked.

I was running on Win7, Tomcat7 with maven-pom setup on Eclipse Mars with maven project enabled. On a NOT running server I only had to change from 3.1 to 3.0 on this screen:

For me it was important to have Dynamic Web Module disabled! Then change the version and then enable Dynamic Web Module again.

You seem to be unnecessarily setting properties on your ComboBox. You can remove the DisplayMemberPath and SelectedValuePath properties which have different uses. It might be an idea for you to take a look at the Difference between SelectedItem, SelectedValue and SelectedValuePath post here for an explanation of these properties. Try this:

<ComboBox Name="cbxSalesPeriods"
    ItemsSource="{Binding SalesPeriods}"
    SelectedItem="{Binding SelectedSalesPeriod}"
    IsSynchronizedWithCurrentItem="True"/>

Furthermore, it is pointless using your displayPeriod property, as the WPF Framework would call the ToString method automatically for objects that it needs to display that don't have a DataTemplate set up for them explicitly.

UPDATE >>>

As I can't see all of your code, I cannot tell you what you are doing wrong. Instead, all I can do is to provide you with a complete working example of how to achieve what you want. I've removed the pointless displayPeriod property and also your SalesPeriodVO property from your class as I know nothing about it... maybe that is the cause of your problem??. Try this:

public class SalesPeriodV
{
    private int month, year;

    public int Year
    {
        get { return year; }
        set
        {
            if (year != value)
            {
                year = value;
                NotifyPropertyChanged("Year");
            }
        }
    }

    public int Month
    {
        get { return month; }
        set
        {
            if (month != value)
            {
                month = value;
                NotifyPropertyChanged("Month");
            }
        }
    }

    public override string ToString()
    {
        return String.Format("{0:D2}.{1}", Month, Year);
    }

    public virtual event PropertyChangedEventHandler PropertyChanged;
    protected virtual void NotifyPropertyChanged(params string[] propertyNames)
    {
        if (PropertyChanged != null)
        {
            foreach (string propertyName in propertyNames) PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            PropertyChanged(this, new PropertyChangedEventArgs("HasError"));
        }
    }
}

Then I added two properties into the view model:

private ObservableCollection<SalesPeriodV> salesPeriods = new ObservableCollection<SalesPeriodV>();
public ObservableCollection<SalesPeriodV> SalesPeriods
{
    get { return salesPeriods; }
    set { salesPeriods = value; NotifyPropertyChanged("SalesPeriods"); }
}
private SalesPeriodV selectedItem = new SalesPeriodV();
public SalesPeriodV SelectedItem
{
    get { return selectedItem; }
    set { selectedItem = value; NotifyPropertyChanged("SelectedItem"); }
}

Then initialised the collection with your values:

SalesPeriods.Add(new SalesPeriodV() { Month = 3, Year = 2013 } );
SalesPeriods.Add(new SalesPeriodV() { Month = 4, Year = 2013 } );

And then data bound only these two properties to a ComboBox:

<ComboBox ItemsSource="{Binding SalesPeriods}" SelectedItem="{Binding SelectedItem}" />

That's it... that's all you need for a perfectly working example. You should see that the display of the items comes from the ToString method without your displayPeriod property. Hopefully, you can work out your mistakes from this code example.

I had the same problem when I was running the plotting commands in separate cells in Jupyter:

In [1]:  %matplotlib inline
         import matplotlib
         import matplotlib.pyplot as plt
         import numpy as np
In [2]:  x = np.array([1, 3, 4])
         y = np.array([1, 5, 3])
In [3]:  fig = plt.figure()
         <Figure size 432x288 with 0 Axes>                      #this might be the problem
In [4]:  ax = fig.add_subplot(1, 1, 1)
In [5]:  ax.scatter(x, y)
Out[5]:  <matplotlib.collections.PathCollection at 0x12341234>  # CAN'T SEE ANY PLOT :(
In [6]:  plt.show()                                             # STILL CAN'T SEE IT :(

The problem was solved by merging the plotting commands into a single cell:

In [1]:  %matplotlib inline
         import matplotlib
         import matplotlib.pyplot as plt
         import numpy as np
In [2]:  x = np.array([1, 3, 4])
         y = np.array([1, 5, 3])
In [3]:  fig = plt.figure()
         ax = fig.add_subplot(1, 1, 1)
         ax.scatter(x, y)
Out[3]:  <matplotlib.collections.PathCollection at 0x12341234>
         # AND HERE APPEARS THE PLOT AS DESIRED :)

Found a solution not involving Flex, because Flex doesn't work in older Browsers. Example:

.container {
    display:block;
    position:relative;
    height:150px;
    width:1024px;
    margin:0 auto;
    padding:0px;
    border:0px;
    background:#ececec;
    margin-bottom:10px;
    text-align:justify;
    box-sizing:border-box;
    white-space:nowrap;
    font-size:0pt;
    letter-spacing:-1em;
}

.cols {
    display:inline-block;
    position:relative;
    width:32%;
    height:100%;
    margin:0 auto;
    margin-right:2%;
    border:0px;
    background:lightgreen;  
    box-sizing:border-box;
    padding:10px;
    font-size:10pt;
    letter-spacing:normal;
}

.cols:last-child {
    margin-right:0;
}

webRTC or websockets? Why not use both.

When building a video/audio/text chat, webRTC is definitely a good choice since it uses peer to peer technology and once the connection is up and running, you do not need to pass the communication via a server (unless using TURN).

When setting up the webRTC communication you have to involve some sort of signaling mechanism. Websockets could be a good choice here, but webRTC is the way to go for the video/audio/text info. Chat rooms is accomplished in the signaling.

But, as you mention, not every browser supports webRTC, so websockets can sometimes be a good fallback for those browsers.

I have been getting the same error for long time.

When i changed session debug to true

Session session = Session.getDefaultInstance(props, new GMailAuthenticator("[email protected]", "xxxxx"));
session.setDebug(true);

I got help url https://support.google.com/mail/answer/78754 from console along with javax.mail.AuthenticationFailedException.

From the steps in the link, I followed each steps. When I changed my password with mix of letters, numbers, and symbols to be my surprise the email was generated without authentication exception.

Note: My old password was more less secure.

Try this

data to load:

<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 4 5'><path fill='#343a40' d='M2 0L0 2h4zm0 5L0 3h4z'/></svg>

get a utf8 to base64 convertor and convert the "svg" string to:

PHN2ZyB4bWxucz0naHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmcnIHZpZXdCb3g9JzAgMCA0IDUn
PjxwYXRoIGZpbGw9JyMzNDNhNDAnIGQ9J00yIDBMMCAyaDR6bTAgNUwwIDNoNHonLz48L3N2Zz4=

and the CSP is

PjxwYXRoIGZpbGw9JyMzNDNhNDAnIGQ9J00yIDBMMCAyaDR6bTAgNUwwIDNoNHonLz48L3N2Zz4=

You can try with this. You have this error because we can not divide by 'zero' (0) value. So we want to validate before when we do calculations.

if ($itemCost != 0 && $itemCost != NULL && $itemQty != 0 && $itemQty != NULL) 
{
    $diffPricePercent = (($actual * 100) / $itemCost) / $itemQty;
}

And also we can validate POST data. Refer following

$itemQty = isset($_POST['num1']) ? $_POST['num1'] : 0;

$itemCost = isset($_POST['num2']) ? $_POST['num2'] : 0;

$itemSale = isset($_POST['num3']) ? $_POST['num3'] : 0;

$shipMat = isset($_POST['num4']) ? $_POST['num4'] : 0;

Please check the following.

<canvas id="myCanvas" width="200" height="100"></canvas>
<div id="mydiv"></div>

JS:

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
ctx.strokeStyle="red";
ctx.moveTo(0,100);
ctx.lineTo(200,0);
ctx.stroke();
ctx.moveTo(0,0);
ctx.lineTo(200,100);
ctx.stroke();

CSS:

html, body { 
  margin: 0;
  padding: 0;
}

#myCanvas {
  padding: 0;
  margin: 0;
  width: 200px;
  height: 100px;
}

#mydiv {
  position: absolute;
  left: 0px;
  right: 0;
  height: 102px;
  width: 202px;
  background: rgba(255,255,255,0);
  padding: 0;
  margin: 0;
}

As stated in one of the comments, this works for Mac (probably for Windows/Linux too):

I WANT TO CONNECT FROM A CONTAINER TO A SERVICE ON THE HOST

The host has a changing IP address (or none if you have no network access). We recommend that you connect to the special DNS name host.docker.internal which resolves to the internal IP address used by the host. This is for development purpose and will not work in a production environment outside of Docker Desktop for Mac.

You can also reach the gateway using gateway.docker.internal.

Quoted from https://docs.docker.com/docker-for-mac/networking/

This worked for me without using --net=host.

So gaiour is right, but if you're looking for a full height item that doesn't scroll with the content, but is actually the height of the container, here's the fix. Have a parent with a height that causes overflow, a content container that has a 100% height and overflow: scroll, and a sibling then can be positioned according to the parent size, not the scroll element size. Here is the fiddle: http://jsfiddle.net/M5cTN/196/

and the relevant code:

html:

<div class="container">
  <div class="inner">
    Lorem ipsum ...
  </div>
  <div class="full-height"></div>
</div>

css:

.container{
  height: 256px;
  position: relative;
}
.inner{
  height: 100%;
  overflow: scroll;
}
.full-height{
  position: absolute;
  left: 0;
  width: 20%;
  top: 0;
  height: 100%;
}

If you have to use the current image and get a darker image then you need to create a new one. Else you can simply reduce the opacity of the .image class and the in the .image:hover you can put a higher value for opacity. But then the image without hover would look pale.

The best way would be to create two images and add the following :

.image {
    background: url('http://cdn1.iconfinder.com/data/icons/round-simple-social-icons/58/facebook.png');
    width: 58px;
    height: 58px;
    opacity:0.9;   
}
.image:hover{
    background: url('http://cdn1.iconfinder.com/data/icons/round-simple-social-icons/58/facebook_hover.png');
}
}

Using jQuery, the following are identical in effect:

$('a').click(function(){ doSomething(); });
$('a').on('click', function(){ doSomething(); });

With the input event, however, only the second pattern seems to work in the browsers I've tested.

Thus, you'd expect this to work, but it DOES NOT (at least currently):

$(':text').input(function(){ doSomething(); });

Again, if you wanted to leverage event delegation (e.g. to set up the event on the #container before your input.text is added to the DOM), this should come to mind:

$('#container').on('input', ':text', function(){ doSomething(); });

Sadly, again, it DOES NOT work currently!

Only this pattern works:

$(':text').on('input', function(){ doSomething(); });

EDITED WITH MORE CURRENT INFORMATION

I can certainly confirm that this pattern:

$('#container').on('input', ':text', function(){ doSomething(); });

NOW WORKS also, in all 'standard' browsers.

Another approach would be like this:

temp = df['Seatblocks'].str.split(' ')
data = data.reindex(data.index.repeat(temp.apply(len)))
data['new_Seatblocks'] = np.hstack(temp)

I was totally lost on why my Gridview.Databind() would not refresh.

My issue, I discovered, was my gridview was inside a UpdatePanel. To get my GridView to FINALLY refresh was this:

gvServerConfiguration.Databind()
uppServerConfiguration.Update()

uppServerConfiguration is the id associated with my UpdatePanel in my asp.net code.

Hope this helps someone.

Ok I have used the last week to massively rewrite my code to precisely fit your test. You can now copy this 1:1 and it will immediately work - including setSingleLine(). Please remember to adjust MIN_TEXT_SIZE and MAX_TEXT_SIZE if you're going for extreme values.

Converging algorithm looks like this:

for (float testSize; (upperTextSize - lowerTextSize) > mThreshold;) {

    // Go to the mean value...
    testSize = (upperTextSize + lowerTextSize) / 2;

    // ... inflate the dummy TextView by setting a scaled textSize and the text...
    mTestView.setTextSize(TypedValue.COMPLEX_UNIT_SP, testSize / mScaledDensityFactor);
    mTestView.setText(text);

    // ... call measure to find the current values that the text WANTS to occupy
    mTestView.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);
    int tempHeight = mTestView.getMeasuredHeight();

    // ... decide whether those values are appropriate.
    if (tempHeight >= targetFieldHeight) {
        upperTextSize = testSize; // Font is too big, decrease upperSize
    }
    else {
        lowerTextSize = testSize; // Font is too small, increase lowerSize
    }
}

And the whole class can be found here.

The result is very flexible now. This works the same declared in xml like so:

<com.example.myProject.AutoFitText
    android:id="@+id/textView"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="4"
    android:text="@string/LoremIpsum" />

... as well as built programmatically like in your test.

I really hope you can use this now. You can call setText(CharSequence text) now to use it by the way. The class takes care of stupendously rare exceptions and should be rock-solid. The only thing that the algorithm does not support yet is:

• Calls to setMaxLines(x) where x >= 2

But I have added extensive comments to help you build this if you wish to!

Please note:

If you just use this normally without limiting it to a single line then there might be word-breaking as you mentioned before. This is an Android feature, not the fault of the AutoFitText. Android will always break words that are too long for a TextView and it's actually quite a convenience. If you want to intervene here than please see my comments and code starting at line 203. I have already written an adequate split and the recognition for you, all you'd need to do henceforth is to devide the words and then modify as you wish.

In conclusion: You should highly consider rewriting your test to also support space chars, like so:

final Random _random = new Random();
final String ALLOWED_CHARACTERS = "qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM1234567890";
final int textLength = _random.nextInt(80) + 20;
final StringBuilder builder = new StringBuilder();
for (int i = 0; i < textLength; ++i) {
    if (i % 7 == 0 && i != 0) {
        builder.append(" ");
    }
    builder.append(ALLOWED_CHARACTERS.charAt(_random.nextInt(ALLOWED_CHARACTERS.length())));
}
((AutoFitText) findViewById(R.id.textViewMessage)).setText(builder.toString());

This will produce very beutiful (and more realistic) results.
You will find commenting to get you started in this matter as well.

Good luck and best regards

Just use the exec-maven-plugin.

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <version>1.2.1</version>
            <configuration>
                <mainClass>com.example.Main</mainClass>
            </configuration>
        </plugin>
    </plugins>
</build>

Then you run you program:

mvn exec:java

The answers that have been given so far will only work the first time that the ng-repeat gets rendered, but if you have a dynamic ng-repeat, meaning that you are going to be adding/deleting/filtering items, and you need to be notified every time that the ng-repeat gets rendered, those solutions won't work for you.

So, if you need to be notified EVERY TIME that the ng-repeat gets re-rendered and not just the first time, I've found a way to do that, it's quite 'hacky', but it will work fine if you know what you are doing. Use this $filter in your ng-repeat before you use any other $filter:

.filter('ngRepeatFinish', function($timeout){
    return function(data){
        var me = this;
        var flagProperty = '__finishedRendering__';
        if(!data[flagProperty]){
            Object.defineProperty(
                data, 
                flagProperty, 
                {enumerable:false, configurable:true, writable: false, value:{}});
            $timeout(function(){
                    delete data[flagProperty];                        
                    me.$emit('ngRepeatFinished');
                },0,false);                
        }
        return data;
    };
})

This will $emit an event called ngRepeatFinished every time that the ng-repeat gets rendered.

How to use it:

<li ng-repeat="item in (items|ngRepeatFinish) | filter:{name:namedFiltered}" >

The ngRepeatFinish filter needs to be applied directly to an Array or an Object defined in your $scope, you can apply other filters after.

How NOT to use it:

<li ng-repeat="item in (items | filter:{name:namedFiltered}) | ngRepeatFinish" >

Do not apply other filters first and then apply the ngRepeatFinish filter.

When should I use this?

If you want to apply certain css styles into the DOM after the list has finished rendering, because you need to have into account the new dimensions of the DOM elements that have been re-rendered by the ng-repeat. (BTW: those kind of operations should be done inside a directive)

What NOT TO DO in the function that handles the ngRepeatFinished event:

• Do not perform a $scope.$apply in that function or you will put Angular in an endless loop that Angular won't be able to detect.

• Do not use it for making changes in the $scope properties, because those changes won't be reflected in your view until the next $digest loop, and since you can't perform an $scope.$apply they won't be of any use.

"But filters are not meant to be used like that!!"

No, they are not, this is a hack, if you don't like it don't use it. If you know a better way to accomplish the same thing please let me know it.

Summarizing

This is a hack, and using it in the wrong way is dangerous, use it only for applying styles after the ng-repeat has finished rendering and you shouldn't have any issues.

I had this problem along with mismatch in ITERATOR_DEBUG_LEVEL. As a sunday-evening problem after all seemed ok and good to go, I was put out for some time. Working in de VS2017 IDE (Solution Explorer) I had recently added/copied a sourcefile reference to my project (ctrl-drag) from another project. Looking into properties->C/C++/Preprocessor - at source file level, not project level - I noticed that in a Release configuration _DEBUG was specified instead of NDEBUG for this source file. Which was all the change needed to get rid of the problem.

For the given json format as in file ~/my-app/src/db/abc.json:

  [
      {
        "name":"Ankit",
        "id":1
      },
      {
        "name":"Aditi",
        "id":2
      },
      {
        "name":"Avani",
        "id":3
      }
  ]

inorder to import to .js file like ~/my-app/src/app.js:

 const json = require("./db/abc.json");

 class Arena extends React.Component{
   render(){
     return(
       json.map((user)=>
        {
          return(
            <div>{user.name}</div>
          )
        }
       )
      }
    );
   }
 }

 export default Arena;

Output:

Ankit Aditi Avani

This may be created sql injection point "SQL Injection Piggy-backed Queries". attackers able to append multiple malicious sql statements. so do not append user inputs directly to the queries.

Security considerations

The API functions mysqli_query() and mysqli_real_query() do not set a connection flag necessary for activating multi queries in the server. An extra API call is used for multiple statements to reduce the likeliness of accidental SQL injection attacks. An attacker may try to add statements such as ; DROP DATABASE mysql or ; SELECT SLEEP(999). If the attacker succeeds in adding SQL to the statement string but mysqli_multi_query is not used, the server will not execute the second, injected and malicious SQL statement.

I had also similar problem. In my case brokerUrl was not configured properly. So that's way I received following Error:

Cause: Error While attempting to add new Connection to the pool: nested exception is javax.jms.JMSException: Could not connect to broker URL : tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused

& I resolved it following way.

   ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();

  connectionFactory.setBrokerURL("tcp://hostname:61616");
  connectionFactory.setUserName("admin");
  connectionFactory.setPassword("admin");

First of all: it is very unfortunate and surprising that R cannot draw error bars "out of the box".

Here is my favourite workaround, the advantage is that you do not need any extra packages. The trick is to draw arrows (!) but with little horizontal bars instead of arrowheads (!!!). This not-so-straightforward idea comes from the R Wiki Tips and is reproduced here as a worked-out example.

Let's assume you have a vector of "average values" avg and another vector of "standard deviations" sdev, they are of the same length n. Let's make the abscissa just the number of these "measurements", so x <- 1:n. Using these, here come the plotting commands:

plot(x, avg,
    ylim=range(c(avg-sdev, avg+sdev)),
    pch=19, xlab="Measurements", ylab="Mean +/- SD",
    main="Scatter plot with std.dev error bars"
)
# hack: we draw arrows but with very special "arrowheads"
arrows(x, avg-sdev, x, avg+sdev, length=0.05, angle=90, code=3)

The result looks like this:

In the arrows(...) function length=0.05 is the size of the "arrowhead" in inches, angle=90 specifies that the "arrowhead" is perpendicular to the shaft of the arrow, and the particularly intuitive code=3 parameter specifies that we want to draw an arrowhead on both ends of the arrow.

For horizontal error bars the following changes are necessary, assuming that the sdev vector now contains the errors in the x values and the y values are the ordinates:

plot(x, y,
    xlim=range(c(x-sdev, x+sdev)),
    pch=19,...)
# horizontal error bars
arrows(x-sdev, y, x+sdev, y, length=0.05, angle=90, code=3)

First off, BigDecimal.multiply() returns a BigDecimal and you're trying to store that in an int.

Second, it takes another BigDecimal as the argument, not an int.

If you just use the BigDecimal for all variables involved in these calculations, it should work fine.

PORT 4369: Erlang makes use of a Port Mapper Daemon (epmd) for resolution of node names in a cluster. Nodes must be able to reach each other and the port mapper daemon for clustering to work.

PORT 35197 set by inet_dist_listen_min/max Firewalls must permit traffic in this range to pass between clustered nodes

RabbitMQ Management console:

• PORT 15672 for RabbitMQ version 3.x
• PORT 55672 for RabbitMQ pre 3.x

PORT 5672 RabbitMQ main port.

For a cluster of nodes, they must be open to each other on 35197, 4369 and 5672.

For any servers that want to use the message queue, only 5672 is required.

I appreciate the answer provided, but I think it would be nice to take it a bit further.

The basic block animation from the documentation

[containerView layoutIfNeeded]; // Ensures that all pending layout operations have been completed
[UIView animateWithDuration:1.0 animations:^{
     // Make all constraint changes here
     [containerView layoutIfNeeded]; // Forces the layout of the subtree animation block and then captures all of the frame changes
}];

but really this is a very simplistic scenario. What if I want to animate subview constraints via the updateConstraints method?

An animation block that calls the subviews updateConstraints method

[self.view layoutIfNeeded];
[self.subView setNeedsUpdateConstraints];
[self.subView updateConstraintsIfNeeded];
[UIView animateWithDuration:1.0f delay:0.0f options:UIViewAnimationOptionLayoutSubviews animations:^{
    [self.view layoutIfNeeded];
} completion:nil];

The updateConstraints method is overridden in the UIView subclass and must call super at the end of the method.

- (void)updateConstraints
{
    // Update some constraints

    [super updateConstraints];
}

The AutoLayout Guide leaves much to be desired but it is worth reading. I myself am using this as part of a UISwitch that toggles a subview with a pair of UITextFields with a simple and subtle collapse animation (0.2 seconds long). The constraints for the subview are being handled in the UIView subclasses updateConstraints methods as described above.

Just to add. If you right-click on an eclipse project and select Properties, select the Java Build Path link on the left. Then select the Source Tab. You'll see a list of all the java source folders. You can even add your own. By default the {project}/src folder is the classpath folder.

Submit a form that contains an input with value of canvas toDataURL('image/png') e.g

//JAVASCRIPT

    var canvas = document.getElementById("canvas");
    var url = canvas.toDataUrl('image/png');

Insert the value of the url to your hidden input on form element.

//PHP

    $data = $_POST['photo'];
    $data = str_replace('data:image/png;base64,', '', $data);
    $data = base64_decode($data);
    file_put_contents("i".  rand(0, 50).".png", $data);

Here is a useful article by Michael J. Swart on the matter, which covers different patterns and antipatterns for implementing UPSERT in SQL Server:
https://michaeljswart.com/2017/07/sql-server-upsert-patterns-and-antipatterns/

It addresses associated concurrency issues (primary key violations, deadlocks) - all of the answers provided here yet are considered antipatterns in the article (except for the @Bridge solution using triggers, which is not covered there).

Here is an extract from the article with the solution preferred by the author:

Inside a serializable transaction with lock hints:

CREATE PROCEDURE s_AccountDetails_Upsert ( @Email nvarchar(4000), @Etc nvarchar(max) )
AS 
  SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
  BEGIN TRAN

    IF EXISTS ( SELECT * FROM dbo.AccountDetails WITH (UPDLOCK) WHERE Email = @Email )

      UPDATE dbo.AccountDetails
         SET Etc = @Etc
       WHERE Email = @Email;

    ELSE 

      INSERT dbo.AccountDetails ( Email, Etc )
      VALUES ( @Email, @Etc );

  COMMIT

Rich Sutton's answer finally worked for me, after I realized that adding access_type=offline is done on the front end client's request for an authorization code, not the back end request that exchanges that code for an access_token. I've added a comment to his answer and this link at Google for more info about refreshing tokens.

P.S. If you are using Satellizer, here is how to add that option to the $authProvider.google in AngularJS.

If you want multiple messages from a queue, say 10 messages, the command to use is:

rabbitmqadmin get queue=<QueueName> ackmode=ack_requeue_true count=10

If you don't want the messages requeued, just change ackmode to ack_requeue_false.

RabbitMQ / AMQP: single queue, multiple consumers for same message and page refresh.

They have wrapped most stuff need to solve your problem, one of the tests looks like this:

String filename = CSSURLEmbedderTest.class.getResource("folder.png").getPath().replace("%20", " ");
String code = "background: url(folder.png);";

StringWriter writer = new StringWriter();
embedder = new CSSURLEmbedder(new StringReader(code), true);
embedder.embedImages(writer, filename.substring(0, filename.lastIndexOf("/")+1));

String result = writer.toString();
assertEquals("background: url(" + folderDataURI + ");", result);

I realize that this is an old question but perhaps someone will find my code sample useful. This code encodes a file in Base64 then decodes it and saves it in a new location.

import java.io.IOException;
import java.nio.file.Files;

import java.nio.file.Paths;

    public static void main(String[] args) {

        Base64Example tempObject = new Base64Example();

        // convert file to regular byte array
        byte[] codedFile = tempObject.convertFileToByteArray("your_input_file_path");

        // encoded file in Base64
        byte[] encodedFile = Base64.encodeBase64(codedFile);

        // print out the byte array
        System.out.println(Arrays.toString(encodedFile));

        // print the encoded String
        System.out.println(encodedFile);

        // decode file back to regular byte array
        byte[] decodedByteArray = Base64.decodeBase64(encodedFile);

        // save decoded byte array to a file
        boolean success = tempObject.saveFileFromByteArray("your_output_file_path", decodedByteArray);

        System.out.println("success : " + success);
    }

As some other answers have already pointed out, there are many reasons why celery would silently ignore tasks, including dependency issues but also any syntax or code problem.

One quick way to find them is to run:

./manage.py check

Many times, after fixing the errors that are reported, the tasks are recognized by celery.

Recently I have worked on my sliding menu implementation version. It uses popular J.Feinstein Android library SlidingMenu.

Please check the source code at GitHub:

https://github.com/baruckis/Android-SlidingMenuImplementation

Download app directly to the device to try:

https://play.google.com/store/apps/details?id=com.baruckis.SlidingMenuImplementation

Code should be self-explanatory because of comments. I hope it will be helpful! ;)

Just use this js file. (I mentioned 2 examples with different js files. hope the second one is what you need) You can simply change the scroll amount, speed etc by changing the parameters.

You can also try this. Here's a demo

I work with a lot of systems that have been mucked by developers "following directions they found on the Internet". It is extremely common that your pip and your python are not looking at the same paths/site-packages. For this reason, when I encounter oddness I start by doing this:

$ python -c 'import sys; print(sys.path)'
['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu',
'/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old',
'/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages',
'/usr/lib/python2.7/dist-packages']

$ pip --version
pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)

That is a happy system.

Below is an unhappy system. (Or at least it's a blissfully ignorant system that causes others to be unhappy.)

$ pip --version
pip 9.0.1 from /usr/local/lib/python3.6/site-packages (python 3.6)

$ which pip pip2 pip3

/usr/local/bin/pip3

It is unhappy because pip is (python3.6 and) using /usr/local/lib/python3.6/site-packages while python is (python2.7 and) using /usr/local/lib/python2.7/site-packages

When I want to make sure I'm installing requirements to the right python, I do this:

$ which -a python python2 python3
/usr/local/bin/python
/usr/bin/python
/usr/local/bin/python2
/usr/local/bin/python3

$ /usr/bin/python -m pip install -r requirements.txt

You've heard, "If it ain't broke, don't try to fix it." The DevOps version of that is, "If you didn't break it and you can work around it, don't try to fix it."

Make sure your id_rsa file doesn't have any extension like .txt or .rtf. Rich Text Format adds additional characters to your file and those gets added to byte array. Which eventually causes invalid private key error. Long story short, Copy the file, not content.

I found that celery purge doesn't work for my more complex celery config. I use multiple named queues for different purposes:

$ sudo rabbitmqctl list_queues -p celery name messages consumers
Listing queues ...  # Output sorted, whitespaced for readability
celery                                          0   2

celeryev.9d023165-ab4a-42cb-86f8-90294b80bd1e   0   1

The first column is the queue name, the second is the number of messages waiting in the queue, and the third is the number of listeners for that queue. The queues are:

• celery - Queue for standard, idempotent celery tasks
• apns - Queue for Apple Push Notification Service tasks, not quite as idempotent
• analytics - Queue for long running nightly analytics
• *.pidbox - Queue for worker commands, such as shutdown and reset, one per worker (2 celery workers, one apns worker, one analytics worker)
• bcast.* - Broadcast queues, for sending messages to all workers listening to a queue (rather than just the first to grab it)
• celeryev.* - Celery event queues, for reporting task analytics

The analytics task is a brute force tasks that worked great on small data sets, but now takes more than 24 hours to process. Occasionally, something will go wrong and it will get stuck waiting on the database. It needs to be re-written, but until then, when it gets stuck I kill the task, empty the queue, and try again. I detect "stuckness" by looking at the message count for the analytics queue, which should be 0 (finished analytics) or 1 (waiting for last night's analytics to finish). 2 or higher is bad, and I get an email.

celery purge offers to erase tasks from one of the broadcast queues, and I don't see an option to pick a different named queue.

Here's my process:

$ sudo /etc/init.d/celeryd stop  # Wait for analytics task to be last one, Ctrl-C
$ ps -ef | grep analytics  # Get the PID of the worker, not the root PID reported by celery
$ sudo kill <PID>
$ sudo /etc/init.d/celeryd stop  # Confim dead
$ python manage.py celery amqp queue.purge analytics
$ sudo rabbitmqctl list_queues -p celery name messages consumers  # Confirm messages is 0
$ sudo /etc/init.d/celeryd start

Simple:

byte[] data = Convert.FromBase64String(encodedString);
string decodedString = Encoding.UTF8.GetString(data);

With the rabbitmq_management plugin installed you can run this to delete all the unwanted queues:

rabbitmqctl list_queues -p vhost_name |\
grep -v "fast\|medium\|slow" |\
tr "[:blank:]" " " |\
cut -d " " -f 1 |\
xargs -I {} curl -i -u guest:guest -H "content-type:application/json" -XDELETE http://localhost:15672/api/queues/<vhost_name>/{}

Let's break the command down:

rabbitmqctl list_queues -p vhost_name will list all the queues and how many task they have currently.

grep -v "fast\|medium\|slow" will filter the queues you don't want to delete, let's say we want to delete every queue without the words fast, medium or slow.

tr "[:blank:]" " " will normalize the delimiter on rabbitmqctl between the name of the queue and the amount of tasks there are

cut -d " " -f 1 will split each line by the whitespace and pick the 1st column (the queue name)

xargs -I {} curl -i -u guest:guest -H "content-type:application/json" -XDELETE http://localhost:15672/api/queues/<vhost>/{} will pick up the queue name and will set it into where we set the {} character deleting all queues not filtered in the process.

I'm not sure if this will help anyone or not, but since it was my problem, I figure it's worth mentioning:

I was getting this error, and it turned out to be a problem with the platform for which the EXE was built. We had it building for x86, and it needed to be x64, because of an Oracle reference in the project. When we made that change, the problem went away. So, see if you have any similar conflicts.

Topics are for the publisher-subscriber model, while queues are for point-to-point.

That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).

Thought to add my solution for this, after spending a few hours on the same error :(

The guys above were correct that the first thing you should check is whether you had missed adding any frameworks, see the steps provided by Pruthvid above.

My problem, it turned out, was a compile class missing after I deleted it, and later added it back in again.

Check your "Compile Sources" as shown for the reported error classes. Add in any missing classes that you created.

In case it helps anyone else, using the new Microsoft Web Service Reference Provider tool, which is for .NET Standard and .NET Core, I had to add the following lines to the binding definition as below:

binding.Security.Mode = BasicHttpSecurityMode.Transport;
binding.Security.Transport = new HttpTransportSecurity{ClientCredentialType = HttpClientCredentialType.Certificate};

This is effectively the same as Micha's answer but in code as there is no config file.

So to incorporate the binding with the instantiation of the web service I did this:

 System.ServiceModel.BasicHttpBinding binding = new System.ServiceModel.BasicHttpBinding();
 binding.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.Transport;
 binding.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Certificate;
 var client = new WebServiceClient(binding, GetWebServiceEndpointAddress());

Where WebServiceClient is the proper name of your web service as you defined it.

You can try viewport units (CSS3):

canvas { 
  height: 100vh; 
  width: 100vw; 
  display: block;
}

Python 3 (and 2)

import base64
a = 'eW91ciB0ZXh0'
base64.b64decode(a)

Python 2

A quick way to decode it without importing anything:

'eW91ciB0ZXh0'.decode('base64')

or more descriptive

>>> a = 'eW91ciB0ZXh0'
>>> a.decode('base64')
'your text'

Tried most of the above and nothing worked. Then turned off the VPN software (NordVPN) and everything was fine.

Two things. First, you must base64 decode the mykey.pem file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec, which is based on the SubjectPublicKeyInfo ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.

import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;

// ...   

String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);

I use a Dictionary and because of the repetetiveness and possible missing keys, I quickly patched together a small method:

 private static string GetKey(IReadOnlyDictionary<string, string> dictValues, string keyValue)
 {
     return dictValues.ContainsKey(keyValue) ? dictValues[keyValue] : "";
 }

Calling it:

var entry = GetKey(dictList,"KeyValue1");

Gets the job done.

You missed out omniORB. This is a pretty full CORBA implementation, so you can also use it to talk to other languages that have CORBA support.

If you don't want to be dependent on static timezone list, or want to display the offset along with timezone.

Here is what I came up with

function timezones()
{
    $timezones = \DateTimeZone::listIdentifiers();
    $items = array();
    foreach($timezones as $timezoneId) {
        $timezone = new \DateTimeZone($timezoneId);
        $offsetInSeconds = $timezone->getOffset(new \DateTime());
        $items[$timezoneId] = $offsetInSeconds;
    }
    asort($items);
    array_walk ($items, function (&$offsetInSeconds, &$timezoneId) { 
        $offsetPrefix = $offsetInSeconds < 0 ? '-' : '+';
        $offset = gmdate('H:i', abs($offsetInSeconds));
        $offset = "(GMT${offsetPrefix}${offset}) ".$timezoneId;
        $offsetInSeconds = $offset;
    });
    return $items;
}

Which gives me the following result

yEnc might work for you:

http://en.wikipedia.org/wiki/Yenc

"yEnc is a binary-to-text encoding scheme for transferring binary files in [text]. It reduces the overhead over previous US-ASCII-based encoding methods by using an 8-bit Extended ASCII encoding method. yEnc's overhead is often (if each byte value appears approximately with the same frequency on average) as little as 1–2%, compared to 33%–40% overhead for 6-bit encoding methods like uuencode and Base64. ... By 2003 yEnc became the de facto standard encoding system for binary files on Usenet."

However, yEnc is an 8-bit encoding, so storing it in a JSON string has the same problems as storing the original binary data — doing it the naïve way means about a 100% expansion, which is worse than base64.

This happened to me as well. For me, Postfix was located at the same server as the PHP script, and the error was happening when I would be using SMTP authentication and smtp.domain.com instead of localhost.

So when I commented out these lines:

$mail->SMTPAuth = true;
$mail->SMTPSecure = "tls";

and set the host to

$mail->Host = "localhost";

instead

$mail->Host = 'smtp.mydomainiuse.com'

and it worked :)

I have used it for my academic project which was online retail website similar to Amazon. JMS was used to handle following features :

1. Update the position of the orders placed by the customers, as the shipment travels from one location to another. This was done by continuously sending messages to JMS Queue.
2. Alerting about any unusual events like shipment getting delayed and then sending email to customer.
3. If the delivery is reached its destination, sending a delivery event.

We had multiple also implemented remote clients connected to main Server. If connection is available, they use to access the main database or if not use their own database. In order to handle data consistency, we had implemented 2PC mechanism. For this, we used JMS for exchange the messages between these systems i.e one acting as coordinator who will initiate the process by sending message on the queue and others will respond accordingly by sending back again a message on the queue. As others have already mentioned, this was similar to pub/sub model.

I guess the following is not the best way to do it (speed and elegance concerns) but well, it could help :

from collections import OrderedDict as od
t = [('pineapple', 5), ('cherry', 7), ('kumquat', 3), ('plum', 11)]
list(od(t).keys()).index('kumquat')
2
list(od(t).values()).index(7)
7
# bonus :
od(t)['kumquat']
3

list of tuples with 2 members can be converted to ordered dict directly, data structures are actually the same, so we can use dict method on the fly.

In my case I had a pem file which contained two certificates and an encrypted private key to be used in mutual SSL authentication. So my pem file looked like this:

-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,C8BF220FC76AA5F9
...
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----

Here is what I did:

Split the file into three separate files, so that each one contains just one entry, starting with "---BEGIN.." and ending with "---END.." lines. Lets assume we now have three files: cert1.pem cert2.pem and pkey.pem

Convert pkey.pem into DER format using openssl and the following syntax:

openssl pkcs8 -topk8 -nocrypt -in pkey.pem -inform PEM -out pkey.der -outform DER

Note, that if the private key is encrypted you need to supply a password( obtain it from the supplier of the original pem file ) to convert to DER format, openssl will ask you for the password like this: "enter a pass phraze for pkey.pem: " If conversion is successful, you will get a new file called "pkey.der"

Create a new java key store and import the private key and the certificates:

String keypass = "password";  // this is a new password, you need to come up with to protect your java key store file
String defaultalias = "importkey";
KeyStore ks = KeyStore.getInstance("JKS", "SUN");

// this section does not make much sense to me, 
// but I will leave it intact as this is how it was in the original example I found on internet:   
ks.load( null, keypass.toCharArray());
ks.store( new FileOutputStream ( "mykeystore"  ), keypass.toCharArray());
ks.load( new FileInputStream ( "mykeystore" ),    keypass.toCharArray());
// end of section..


// read the key file from disk and create a PrivateKey

FileInputStream fis = new FileInputStream("pkey.der");
DataInputStream dis = new DataInputStream(fis);
byte[] bytes = new byte[dis.available()];
dis.readFully(bytes);
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);

byte[] key = new byte[bais.available()];
KeyFactory kf = KeyFactory.getInstance("RSA");
bais.read(key, 0, bais.available());
bais.close();

PKCS8EncodedKeySpec keysp = new PKCS8EncodedKeySpec ( key );
PrivateKey ff = kf.generatePrivate (keysp);


// read the certificates from the files and load them into the key store:

Collection  col_crt1 = CertificateFactory.getInstance("X509").generateCertificates(new FileInputStream("cert1.pem"));
Collection  col_crt2 = CertificateFactory.getInstance("X509").generateCertificates(new FileInputStream("cert2.pem"));

Certificate crt1 = (Certificate) col_crt1.iterator().next();
Certificate crt2 = (Certificate) col_crt2.iterator().next();
Certificate[] chain = new Certificate[] { crt1, crt2 };

String alias1 = ((X509Certificate) crt1).getSubjectX500Principal().getName();
String alias2 = ((X509Certificate) crt2).getSubjectX500Principal().getName();

ks.setCertificateEntry(alias1, crt1);
ks.setCertificateEntry(alias2, crt2);

// store the private key
ks.setKeyEntry(defaultalias, ff, keypass.toCharArray(), chain );

// save the key store to a file         
ks.store(new FileOutputStream ( "mykeystore" ),keypass.toCharArray());

(optional) Verify the content of your new key store:

keytool -list -keystore mykeystore -storepass password

Keystore type: JKS Keystore provider: SUN

Your keystore contains 3 entries

cn=...,ou=...,o=.., Sep 2, 2014, trustedCertEntry, Certificate fingerprint (SHA1): 2C:B8: ...

importkey, Sep 2, 2014, PrivateKeyEntry, Certificate fingerprint (SHA1): 9C:B0: ...

cn=...,o=...., Sep 2, 2014, trustedCertEntry, Certificate fingerprint (SHA1): 83:63: ...

(optional) Test your certificates and private key from your new key store against your SSL server: ( You may want to enable debugging as an VM option: -Djavax.net.debug=all )

        char[] passw = "password".toCharArray();
        KeyStore ks = KeyStore.getInstance("JKS", "SUN");
        ks.load(new FileInputStream ( "mykeystore" ), passw );

        KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
        kmf.init(ks, passw);

        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(ks);
        TrustManager[] tm = tmf.getTrustManagers();

        SSLContext sclx = SSLContext.getInstance("TLS");
        sclx.init( kmf.getKeyManagers(), tm, null);

        SSLSocketFactory factory = sclx.getSocketFactory();
        SSLSocket socket = (SSLSocket) factory.createSocket( "192.168.1.111", 443 );
        socket.startHandshake();

        //if no exceptions are thrown in the startHandshake method, then everything is fine..

Finally register your certificates with HttpsURLConnection if plan to use it:

        char[] passw = "password".toCharArray();
        KeyStore ks = KeyStore.getInstance("JKS", "SUN");
        ks.load(new FileInputStream ( "mykeystore" ), passw );

        KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
        kmf.init(ks, passw);

        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(ks);
        TrustManager[] tm = tmf.getTrustManagers();

        SSLContext sclx = SSLContext.getInstance("TLS");
        sclx.init( kmf.getKeyManagers(), tm, null);

        HostnameVerifier hv = new HostnameVerifier()
        {
            public boolean verify(String urlHostName, SSLSession session)
            {
                if (!urlHostName.equalsIgnoreCase(session.getPeerHost()))
                {
                    System.out.println("Warning: URL host '" + urlHostName + "' is different to SSLSession host '" + session.getPeerHost() + "'.");
                }
                return true;
            }
        };

        HttpsURLConnection.setDefaultSSLSocketFactory( sclx.getSocketFactory() );
        HttpsURLConnection.setDefaultHostnameVerifier(hv);

I'm using zeroMQ. I wanted a simple message passing system and I don't need the complication of a broker. I also don't want a huge Java oriented enterprise system.

If you want a fast, simple system and you need to support multiple languages (I use C and .net) then I'd recommend looking at 0MQ.

stuff is an object and push is a method of an array. So you cannot use stuff.push(..).

Lets say you define stuff as an array stuff = []; then you can call push method on it.

This works because the object[key/value] is well formed.

stuff.push( {'name':$(this).attr('checked')} );

Whereas this will not work because the object is not well formed.

stuff.push( {$(this).attr('value'):$(this).attr('checked')} );

This works because we are treating stuff as an associative array and added values to it

stuff[$(this).attr('value')] = $(this).attr('checked');

I don't think answer from Vincent Malgrat is correct. When NVARCHAR2 was introduced long time ago nobody was even talking about Unicode.

Initially Oracle provided VARCHAR2 and NVARCHAR2 to support localization. Common data (include PL/SQL) was hold in VARCHAR2, most likely US7ASCII these days. Then you could apply NLS_NCHAR_CHARACTERSET individually (e.g. WE8ISO8859P1) for each of your customer in any country without touching the common part of your application.

Nowadays character set AL32UTF8 is the default which fully supports Unicode. In my opinion today there is no reason anymore to use NLS_NCHAR_CHARACTERSET, i.e. NVARCHAR2, NCHAR2, NCLOB. Note, there are more and more Oracle native functions which do not support NVARCHAR2, so you should really avoid it. Maybe the only reason is when you have to support mainly Asian characters where AL16UTF16 consumes less storage compared to AL32UTF8.

In case someone wants to actually knock out SQL statement logging (without changing logging level, and while keeping the logging from their AR models):

The line that writes to the log (in Rails 3.2.16, anyway) is the call to debug in lib/active_record/log_subscriber.rb:50.

That debug method is defined by ActiveSupport::LogSubscriber.

So we can knock out the logging by overwriting it like so:

module ActiveSupport
  class LogSubscriber
    def debug(*args, &block)
    end
  end
end

As @HarlemSquirrel posted, it is the best and I think the correct solution.

But, to answer the OP specific problem, it should be something like the following command, as he doesn't want to recreate ALL services in the docker-compose.yml file, but only the nginx one:

docker-compose up -d --force-recreate --no-deps --build nginx

                      --abort-on-container-exit.
  --force-recreate    Recreate containers even if their configuration

If anyone is including a custom argLine argument, you must reconsider because it is likely the source of your issues with the memory allocation.

For Example (I used to have):

<argLine>XX:MaxPermSize=4096m ${argLine}</argLine>

Now I use hard specified values:

<argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>

For whatever reason, Applications that integrate with Surefire such as Jacoco, dont request enough memory to coexist with the testing that happens at build time.

A List is an ordered Collection of elements. You can add them with the add method, and retrieve them with the get(int index) method. You can also iterate over a List, remove elements, etc. Here are some basic examples of using a List:

List<String> names = new ArrayList<String>(3); // 3 because we expect the list 
    // to have 3 entries.  If we didn't know how many entries we expected, we
    // could leave this empty or use a LinkedList instead
names.add("Alice");
names.add("Bob");
names.add("Charlie");
System.out.println(names.get(2)); // prints "Charlie"
System.out.println(names); // prints the whole list
for (String name: names) {
    System.out.println(name);  // prints the names in turn.
}

+1 for everyone who's recommended the RedGate tools, with an additional recommendation and a caveat.

SqlCompare also has a decently documented API: so you can, for instance, write a console app which syncs your source controlled scripts folder with a CI integration testing database on checkin, so that when someone checks in a change to the schema from their scripts folder it's automatically deployed along with the matching application code change. This helps close the gap with developers who are forgetful about propagating changes in their local db up to a shared development DB (about half of us, I think :) ).

A caveat is that with a scripted solution or otherwise, the RedGate tools are sufficiently smooth that it's easy to forget about SQL realities underlying the abstraction. If you rename all the columns in a table, SqlCompare has no way to map the old columns to the new columns and will drop all the data in the table. It will generate warnings but I've seen people click past that. There's a general point here worth making, I think, that you can only automate DB versioning and upgrade so far - the abstractions are very leaky.

To set settings on the client:

AndroidHttpClient client = AndroidHttpClient.newInstance("Awesome User Agent V/1.0");
HttpConnectionParams.setConnectionTimeout(client.getParams(), 3000);
HttpConnectionParams.setSoTimeout(client.getParams(), 5000);

You need to put the "\n" in the strings.xml file not within the page layout.

This following solution worked for me. In the following configuration file:

C:\Users\<user>\.android\avd\<avd-profile-name>.avd\config.ini

Replace

hw.ramSize=1024

by

hw.ramSize=1024MB

I wanted to share how you can use this to change a attribute of the button, because it took me some time to figure it out...

For example in order to change it's background to yellow:

$("#"+String(this.id)).css("background-color","yellow");

I had the same issue with my Android app. I was trying out notifications and found that notifications were showing on my Android emulator which ran a Android 7.0 (Nougat) system, whereas it wasn't running on my phone which had Android 8.1 (Oreo).

After reading the documentation, I found that Android had a feature called notification channel, without which notifications won't show up on Oreo devices. Below is the link to official Android documentation on notification channels.

Try the following:

• Close Eclipse.
• Restart your phone.
• End adb.exe process in Task Manager (Windows). In Mac, force close in Activity Monitor.
• Issue kill and start command in \platform-tools\
  • C:\sdk\platform-tools>adb kill-server
  • C:\sdk\platform-tools>adb start-server
• If it says something like 'started successfully', you are good.

== takes precedence over in, so you're actually testing word == True.

>>> w = 'ab c'
>>> ' ' in w == True
1: False
>>> (' ' in w) == True
2: True

But you don't need == True at all. if requires [something that evalutes to True or False] and ' ' in word will evalute to true or false. So, if ' ' in word: ... is just fine:

>>> ' ' in w
3: True

Since i have found issue uploading file in IE browser i would suggest to handle it like this.

View

@using (Html.BeginForm("UploadFile", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <input type="file" name="file" />
    <input type="submit" value="Submit" />
}

Controller

public class HomeController : Controller
{
    public ActionResult UploadFile()
    {
        return View();
    }

    [HttpPost]
    public ActionResult UploadFile(MyModal Modal)
    {
            string DocumentName = string.Empty;
            string Description = string.Empty;

            if (!String.IsNullOrEmpty(Request.Form["DocumentName"].ToString()))
                DocumentName = Request.Form["DocumentName"].ToString();
            if (!String.IsNullOrEmpty(Request.Form["Description"].ToString()))
                Description = Request.Form["Description"].ToString();

            if (!String.IsNullOrEmpty(Request.Form["FileName"].ToString()))
                UploadedDocument = Request.Form["FileName"].ToString();

            HttpFileCollectionBase files = Request.Files;

            string filePath = Server.MapPath("~/Root/Documents/");
            if (!(Directory.Exists(filePath)))
                Directory.CreateDirectory(filePath);
            for (int i = 0; i < files.Count; i++)
            {
                HttpPostedFileBase file = files[i];
                // Checking for Internet Explorer  
                if (Request.Browser.Browser.ToUpper() == "IE" || Request.Browser.Browser.ToUpper() == "INTERNETEXPLORER")
                {
                    string[] testfiles = file.FileName.Split(new char[] { '\\' });
                    fname = testfiles[testfiles.Length - 1];
                    UploadedDocument = fname;
                }
                else
                {
                    fname = file.FileName;
                    UploadedDocument = file.FileName;
                }
                file.SaveAs(fname);
                return RedirectToAction("List", "Home");
}

Using Accept header is really easy to get the format json or xml from the REST service.

This is my Controller, take a look produces section.

@RequestMapping(value = "properties", produces = {MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_XML_VALUE}, method = RequestMethod.GET)
    public UIProperty getProperties() {
        return uiProperty;
    }

In order to consume the REST service we can use the code below where header can be MediaType.APPLICATION_JSON_VALUE or MediaType.APPLICATION_XML_VALUE

HttpHeaders headers = new HttpHeaders();
headers.add("Accept", header);

HttpEntity entity = new HttpEntity(headers);

RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8080/properties", HttpMethod.GET, entity,String.class);
return response.getBody();

Edit 01:

In order to work with application/xml, add this dependency

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
</dependency>

Just run

docker restart $(docker ps -q)

Update

For Docker 1.13.1 use docker restart $(docker ps -a -q) as in answer lower.

I use this trick:

.pvw-title {
    text-indent: -999px;
}
.pvw-title:after {
    text-indent: 0px;
    float: left;
    content: 'My New Content';
}

I've even used this to handle internationalization of pages by just changing a base class...

.translate-es .welcome {
    text-indent: -999px;
}
.translate-es .welcome:after {
    text-indent: 0px;
    float: left;
    content: '¡Bienvenidos!';
}

function get_attribute(){ alert( $(this).attr("data-id") ); }

If you like the idea of Views, but are worried about performance you can get Oracle to create a cached table representing the view which oracle keeps up to date.
See materialized views

Array to string conversion in latest versions of php 7.x is error, rather than notice, and prevents further code execution.

Using print, echo on array is not an option anymore.

Suppressing errors and notices is not a good practice, especially when in development environment and still debugging code.

Use var_dump,print_r, iterate through input value using foreach or for to output input data for names that are declared as input arrays ('name[]')

Most common practice to catch errors is using try/catch blocks, that helps us prevent interruption of code execution that might cause possible errors wrapped within try block.

  try{  //wrap around possible cause of error or notice
    
    if(!empty($_POST['C'])){
        echo $_POST['C'];
    }

  }catch(Exception $e){

    //handle the error message $e->getMessage();
  }

You could try letting the stream throw an exception on failure:

std::ifstream f;
//prepare f to throw if failbit gets set
std::ios_base::iostate exceptionMask = f.exceptions() | std::ios::failbit;
f.exceptions(exceptionMask);

try {
  f.open(fileName);
}
catch (std::ios_base::failure& e) {
  std::cerr << e.what() << '\n';
}

e.what(), however, does not seem to be very helpful:

• I tried it on Win7, Embarcadero RAD Studio 2010 where it gives "ios_base::failbit set" whereas strerror(errno) gives "No such file or directory."
• On Ubuntu 13.04, gcc 4.7.3 the exception says "basic_ios::clear" (thanks to arne)

If e.what() does not work for you (I don't know what it will tell you about the error, since that's not standardized), try using std::make_error_condition (C++11 only):

catch (std::ios_base::failure& e) {
  if ( e.code() == std::make_error_condition(std::io_errc::stream) )
    std::cerr << "Stream error!\n"; 
  else
    std::cerr << "Unknown failure opening file.\n";
}

The one I always use is here http://blog.neutrino.es/2012/git-copy-a-file-or-directory-from-another-repository-preserving-history/ . Simple and fast.

For compliance with stackoverflow standards, here is the procedure:

mkdir /tmp/mergepatchs
cd ~/repo/org
export reposrc=myfile.c #or mydir
git format-patch -o /tmp/mergepatchs $(git log $reposrc|grep ^commit|tail -1|awk '{print $2}')^..HEAD $reposrc
cd ~/repo/dest
git am /tmp/mergepatchs/*.patch

Enyo's tutorial is excellent.

I found that the sample script in the tutorial worked well for a button embedded in the dropzone (i.e., the form element). If you wish to have the button outside the form element, I was able to accomplish it using a click event:

First, the HTML:

<form id="my-awesome-dropzone" action="/upload" class="dropzone">  
    <div class="dropzone-previews"></div>
    <div class="fallback"> <!-- this is the fallback if JS isn't working -->
        <input name="file" type="file" multiple />
    </div>

</form>
<button type="submit" id="submit-all" class="btn btn-primary btn-xs">Upload the file</button>

Then, the script tag....

Dropzone.options.myAwesomeDropzone = { // The camelized version of the ID of the form element

    // The configuration we've talked about above
    autoProcessQueue: false,
    uploadMultiple: true,
    parallelUploads: 25,
    maxFiles: 25,

    // The setting up of the dropzone
    init: function() {
        var myDropzone = this;

        // Here's the change from enyo's tutorial...

        $("#submit-all").click(function (e) {
            e.preventDefault();
            e.stopPropagation();
            myDropzone.processQueue();
        }); 
    }
}

this one is working

        $.get('1.txt', function(data) {
            //var fileDom = $(data);

            var lines = data.split("\n");

            $.each(lines, function(n, elem) {
                $('#myContainer').append('<div>' + elem + '</div>');
            });
        });

How about something like this :

string url = "http://www.example.com/aaa/bbb.jpg";
Uri uri = new Uri(url);
string path_Query = uri.PathAndQuery;
string extension =  Path.GetExtension(path_Query);

path_Query = path_Query.Replace(extension, string.Empty);// This will remove extension

require section This section contains the packages/dependencies which are better candidates to be installed/required in the production environment.

require-dev section: This section contains the packages/dependencies which can be used by the developer to test her code (or to experiment on her local machine and she doesn't want these packages to be installed on the production environment).

Actually I think you may need to use if (value !== null || value !== undefined) because if you use if (value) you may also filter 0 or false values.

Consider these two functions:

const firstTest = value => {
    if (value) {
        console.log('passed');
    } else {
        console.log('failed');
    }
}
const secondTest = value => {
    if (value !== null && value !== undefined) {
        console.log('passed');
    } else {
        console.log('failed');
    }
}

firstTest(0);            // result: failed
secondTest(0);           // result: passed

firstTest(false);        // result: failed
secondTest(false);       // result: passed

firstTest('');           // result: failed
secondTest('');          // result: passed

firstTest(null);         // result: failed
secondTest(null);        // result: failed

firstTest(undefined);    // result: failed
secondTest(undefined);   // result: failed

In my situation, I just needed to check if the value is null and undefined and I did not want to filter 0 or false or '' values. so I used the second test, but you may need to filter them too which may cause you to use first test.

Have you tried: getElementbyId('ID_OF_ID').innerHTML?

Quick adjustment - for those of you having trouble with the global configuration of the transformRequest function, here's the snippet i'm using to get rid of the Cannot read property 'jquery' of undefined error:

$httpProvider.defaults.transformRequest = function(data) {
        return data != undefined ? $.param(data) : null;
    }

Simple Example:

print("foo %d, bar %d" % (1,2))

Thanks for the info, think I see the problem. This is a bug in hive-go that only shows up when you add a host. The last lines of it are:

app.listen(3001);
console.log("... port %d in %s mode", app.address().port, app.settings.env);

When you add the host on the first line, it is crashing when it calls app.address().port.

The problem is the potentially asynchronous nature of .listen(). Really it should be doing that console.log call inside a callback passed to listen. When you add the host, it tries to do a DNS lookup, which is async. So when that line tries to fetch the address, there isn't one yet because the DNS request is running, so it crashes.

Try this:

app.listen(3001, 'localhost', function() {
  console.log("... port %d in %s mode", app.address().port, app.settings.env);
});

<style name="MineCustomTabText" parent="TextAppearance.Design.Tab">
    <item name="android:textSize">16sp</item>

            ...
            />

A fine example found here. Powerlord got it right, below, for POST you need HttpURLConnection, instead.

Below is the code to do that,

    URL url = new URL(urlString);
    URLConnection conn = url.openConnection();
    conn.setDoOutput(true);
    conn.setRequestProperty ("Authorization", encodedCredentials);

    OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());

    writer.write(data);
    writer.flush();
    String line;
    BufferedReader reader = new BufferedReader(new 
                                     InputStreamReader(conn.getInputStream()));
    while ((line = reader.readLine()) != null) {
      System.out.println(line);
    }

Change URLConnection to HttpURLConnection, to make it POST request.

    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setRequestMethod("POST");

Suggestion (...in comments):

You might need to set these properties too,

conn.setRequestProperty( "Content-type", "application/x-www-form-urlencoded");
conn.setRequestProperty( "Accept", "*/*" );

You need to install ssh2 lib

sudo apt-get install libssh2-php && sudo /etc/init.d/apache2 restart

that should be enough to get you on the road

Open the Console view, locate the console for your running app and hit the Big Red Button.

Alternatively if you open the Debug perspective you will see all running apps in (by default) the top left. You can select the one that's causing you grief and once again hit the Big Red Button.

Below are some of the way by which you can create a link button in MVC.

@Html.ActionLink("Admin", "Index", "Home", new { area = "Admin" }, null)  
@Html.RouteLink("Admin", new { action = "Index", controller = "Home", area = "Admin" })

If the header file is /usr/include/sdl/SDL.h and your code has:

#include "SDL.h"

You need to either fix your code:

#include "sdl/SDL.h"

Or tell the preprocessor where to find include files:

CFLAGS = ... -I/usr/include/sdl ...

grep -E "(string)" /path/to/file || echo "no match found"

-E option makes grep use regular expressions

There are many possibilities to solve this task.

1. RUN the batch file with full path

The easiest solution is running the batch file with full path.

"F:\- Big Packets -\kitterengine\Common\Template.bat"

Once end of batch file Template.bat is reached, there is no return to previous script in case of the command line above is within a *.bat or *.cmd file.

The current directory for the batch file Template.bat is the current directory of the current process. In case of Template.bat requires that the directory of this batch file is the current directory, the batch file Template.bat should contain after @echo off as second line the following command line:

cd /D "%~dp0"

Run in a command prompt window cd /? for getting displayed the help of this command explaining parameter /D ... change to specified directory also on a different drive.

Run in a command prompt window call /? for getting displayed the help of this command used also in 2., 4. and 5. solution and explaining also %~dp0 ... drive and path of argument 0 which is the name of the batch file.

2. CALL the batch file with full path

Another solution is calling the batch file with full path.

call "F:\- Big Packets -\kitterengine\Common\Template.bat"

The difference to first solution is that after end of batch file Template.bat is reached the batch processing continues in batch script containing this command line.

For the current directory read above.

3. Change directory and RUN batch file with one command line

There are 3 operators for running multiple commands on one command line: &, && and ||.
For details see answer on Single line with multiple commands using Windows batch file

I suggest for this task the && operator.

cd /D "F:\- Big Packets -\kitterengine\Common" && Template.bat

As on first solution there is no return to current script if this is a *.bat or *.cmd file and changing the directory and continuation of batch processing on Template.bat is successful.

4. Change directory and CALL batch file with one command line

This command line changes the directory and on success calls the batch file.

cd /D "F:\- Big Packets -\kitterengine\Common" && call Template.bat

The difference to third solution is the return to current batch script on exiting processing of Template.bat.

5. Change directory and CALL batch file with keeping current environment with one command line

The four solutions above change the current directory and it is unknown what Template.bat does regarding

1. current directory
2. environment variables
3. command extensions state
4. delayed expansion state

In case of it is important to keep the environment of current *.bat or *.cmd script unmodified by whatever Template.bat changes on environment for itself, it is advisable to use setlocal and endlocal.

Run in a command prompt window setlocal /? and endlocal /? for getting displayed the help of these two commands. And read answer on change directory command cd ..not working in batch file after npm install explaining more detailed what these two commands do.

setlocal & cd /D "F:\- Big Packets -\kitterengine\Common" & call Template.bat & endlocal

Now there is only & instead of && used as it is important here that after setlocal is executed the command endlocal is finally also executed.

ONE MORE NOTE

If batch file Template.bat contains the command exit without parameter /B and this command is really executed, the command process is always exited independent on calling hierarchy. So make sure Template.bat contains exit /B or goto :EOF instead of just exit if there is exit used at all in this batch file.

In Java, all strings are immutable(Can't change). When you are trying to modify a String, what you are really doing is creating a new one.

Following ways we can create the string object

1. Using String literal

   String str="java";
   

2. Using new keyword

   String str = new String("java");
   

3. Using character array

   char[] helloArray = { 'h', 'e', 'l', 'l', 'o', '.' };
   
   String helloString = new String(helloArray);   
   

coming to String immutability, simply means unmodifiable or unchangeable

Let's take one example

I'm initializing the value to the String literal s

String s="kumar";

Below I'm going to display the decimal representation of the location address using hashcode()

System.out.println(s.hashCode());

Simply printing the value of a String s

System.out.println("value "+s);

Okay, this time I'm inittializing value "kumar" to s1

String s1="kumar";   // what you think is this line, takes new location in the memory ??? 

Okay let's check by displaying hashcode of the s1 object which we created

System.out.println(s1.hashCode());

okay, let's check below code

String s2=new String("Kumar");
    System.out.println(s2.hashCode());  // why this gives the different address ??

Okay, check this below code at last

String s3=new String("KUMAR");
    System.out.println(s3.hashCode());  // again different address ???

YES, if you see Strings 's' and 's1' having the same hashcode because the value hold by 's' & 's1' are same that is 'kumar'

Let's consider String 's2' and 's3' these two Strings hashcode appears to be different in the sense, they both stored in a different location because you see their values are different.

since s and s1 hashcode is same because those values are same and storing in the same location.

Example 1: Try below code and analyze line by line

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

    String s="java";
    System.out.println(s.hashCode());
    String s1="javA";
    System.out.println(s1.hashCode());
    String s2=new String("Java");
    System.out.println(s2.hashCode());
    String s3=new String("JAVA");
    System.out.println(s3.hashCode());
}
}

Example 2: Try below code and analyze line by line

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

        String s="java";
        s.concat(" programming");  // s can not be changed "immutablity"
        System.out.println("value of s "+s);
        System.out.println(" hashcode of s "+s.hashCode());

        String s1="java";
        String s2=s.concat(" programming");   // s1 can not be changed "immutablity" rather creates object s2
        System.out.println("value of s1 "+s1);
        System.out.println(" hashcode of s1 "+s1.hashCode());  

        System.out.println("value of s2 "+s2);
        System.out.println(" hashcode of s2 "+s2.hashCode());

    }
}

Okay, Let's look what is the difference between mutable and immutable.

mutable(it change) vs. immutable (it can't change)

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


        // it demonstrates immutable concept
        String s="java";
        s.concat(" programming");  // s can not be changed (immutablity)
        System.out.println("value of s ==  "+s); 
        System.out.println(" hashcode of s == "+s.hashCode()+"\n\n");


        // it demonstrates mutable concept
        StringBuffer s1= new StringBuffer("java");
        s1.append(" programming");  // s can be changed (mutablity)
        System.out.println("value of s1 ==  "+s1); 
        System.out.println(" hashcode of s1 == "+s1.hashCode());


    }
}

It may be possible to use XSLT with JSON. Verson 3 of XPath(3.1) XSLT(3.0) and XQuery(3.1) supports JSON in some way. This seems to be available in the commercial version of Saxon, and might at some point be included in the HE version. https://www.saxonica.com/html/documentation/functions/fn/parse-json.html

-

What I would expect from an alternative solution:

I would want to be able input JSON to fetch a matching set of data, and output JSON or TEXT.

Access arbitrary properties and evaluate the values

Support for conditional logic

I would want the transformation scripts to be external from the tool, text based, and preferably a commonly used language.

Potential alternative?

I wonder if SQL could be a suitable alternative. https://docs.microsoft.com/en-us/sql/relational-databases/json/json-data-sql-server

It would be nice if the alternative tool could handle JSON and XML https://docs.microsoft.com/en-us/sql/relational-databases/xml/openxml-sql-server

I have not yet tried to convert the XSLT scripts I use to SQL, or fully evaluated this option yet, but I hope to look into it more soon. Just some thoughts so far.

For me this was caused by the Build target having been rewritten to not output the dll. Removing this to fall back on the default Build target fixed the issue.

int.from_bytes( bytes, byteorder, *, signed=False )

doesn't work with me I used function from this website, it works well

https://coderwall.com/p/x6xtxq/convert-bytes-to-int-or-int-to-bytes-in-python

def bytes_to_int(bytes):
    result = 0
    for b in bytes:
        result = result * 256 + int(b)
    return result

def int_to_bytes(value, length):
    result = []
    for i in range(0, length):
        result.append(value >> (i * 8) & 0xff)
    result.reverse()
    return result

The exec(3,3p) functions replace the current process with another. That is, the current process stops, and another runs instead, taking over some of the resources the original program had.

From ISO 8601 String to Java Date Object

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
sdf.parse("2013-09-29T18:46:19Z"); //prints-> Mon Sep 30 02:46:19 CST 2013

if you don't set TimeZone.getTimeZone("GMT") then it will output Sun Sep 29 18:46:19 CST 2013

From Java Date Object to ISO 8601 String

And to convert Dateobject to ISO 8601 Standard (yyyy-MM-dd'T'HH:mm:ss'Z') use following code

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'", Locale.US);
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));           
System.out.println(sdf.format(new Date())); //-prints-> 2015-01-22T03:23:26Z

Also note that without ' ' at Z yyyy-MM-dd'T'HH:mm:ssZ prints 2015-01-22T03:41:02+0000

you need to use add class open in <div class="btn-group open">

You can reference Microsoft.VisualBasic.dll.

Then using the code below.

Microsoft.VisualBasic.Interaction.InputBox("Question?","Title","Default Text");

Alternatively, by adding a using directive allowing for a shorter syntax in your code (which I'd personally prefer).

using Microsoft.VisualBasic;
...
Interaction.InputBox("Question?","Title","Default Text");

Or you can do what Pranay Rana suggests, that's what I would've done too...

Merge commits: retains all of the commits in your branch and interleaves them with commits on the base branch

Merge Squash: retains the changes but omits the individual commits from history

Rebase: This moves the entire feature branch to begin on the tip of the master branch, effectively incorporating all of the new commits in master

You can use TRIM('"' FROM '"this "is" a test"') which returns: this "is" a test

Java usually doesn't like accessing hardware, so you will need a driver program of some sort, as goldenmean said. I've done this on my laptop by finding a command line program that snaps a picture. Then it's the same as goldenmean explained; you run the command line program from your java program in the takepicture() routine, and the rest of your code runs the same.

Except for the part about reading pixel values into an array, you might be better served by saving the file to BMP, which is nearly that format already, then using the standard java image libraries on it.

Using a command line program adds a dependency to your program and makes it less portable, but so was the webcam, right?

If you think about it, a body XRay scan (at the medical center) too needs this kind of measurement for estimating size of tumors. So they place a 1 Dollar Coin on the body, to do a comparative measurement.

Even newspaper is printed with some marks on the corners.

You need a reference to measure. May be you can get your person to wear a cap which has a few bright green circles. Once you recognize the size of the circle you can comparatively measure the remaining.

Or you can create a transparent 1 inch circle which will superimpose on the face, move the camera toward/away the face, aim your superimposed circle on that bright green circle on the cap. Then on your photo will be as per scale.

If you're not wanting to save changes set savechanges to false

    Sub CloseBook2()
        ActiveWorkbook.Close savechanges:=False

Try to match all version:

compileSdkVersion 23
buildToolsVersion '23.0.0'
targetSdkVersion 23
compile 'com.android.support:appcompat-v7:23.0.0'

It's work for me.

It's actually a sensible question. Here's the answer from Excel 2010 help:

"The Workbook object is a member of the Workbooks collection. The Workbooks collection contains all the Workbook objects currently open in Microsoft Excel."

So, since that workbook isn't open - at least I assume it isn't - it can't be set as a workbook object. If it was open you'd just set it like:

Set wbk = workbooks("Master Benchmark Data Sheet.xlsx")

For those having a portable SDK edition on windows, simply add the 2 following path to your system.

F:\ADT_SDK\sdk\platforms
F:\ADT_SDK\sdk\platform-tools

This worked for me.

I'm not sure how browsers handle clicks on type="file" elements (security concerns and all), but this should work:

If, like me, you use Spyder IDE, you have to disable the interactive mode with :

plt.ioff()

If you want to enable it again, use :

I was hitting the same issue. Added mysql service port number(3307), resolved the issue.

C# does not have a seperate runtime library. It uses .NET as a runtime library.

In addition to the accepted answer from 2009. If you can can target modern browsers, one can make use of the Object.defineProperty.

The Object.defineProperty() method defines a new property directly on an object, or modifies an existing property on an object, and returns the object. Source: Mozilla

var Foo = (function () {
    function Foo() {
        this._bar = false;
    }
    Object.defineProperty(Foo.prototype, "bar", {
        get: function () {
            return this._bar;
        },
        set: function (theBar) {
            this._bar = theBar;
        },
        enumerable: true,
        configurable: true
    });
    Foo.prototype.toTest = function () {
        alert("my value is " + this.bar);
    };
    return Foo;
}());

// test instance
var test = new Foo();
test.bar = true;
test.toTest();

Since I don't see the jQuery tag in the OP, here is a javascript only option :

document.addEventListener("DOMContentLoaded", function (event) {

    _selector.addEventListener('change', function (event) {
        if (_selector.checked) {
            // do something if checked
        } else {
            // do something else otherwise
        }

You can check with null or Number.

First, add a reference to Microsoft.VisualBasic in your application.

Then, use the following code:

bool b = Microsoft.VisualBasic.Information.IsNumeric("null");
bool c = Microsoft.VisualBasic.Information.IsNumeric("abc");

In the above, b and c should both be false.

It's very easy for Kotlin!

listToBeSorted.sortBy { it.distance }

OnClientClick="SomeMethod()" event of that BUTTON, it return by default "true" so after that function it do postback

for solution use

//use this code in BUTTON  ==>   OnClientClick="return SomeMethod();"

//and your function like this
<script type="text/javascript">
  function SomeMethod(){
    // put your code here 
    return false;
  }
</script>

The only way I got this to work on my machine was to do it this way:

# Ignore all directories, and all sub-directories, and it's contents:
*/*

#Now ignore all files in the current directory 
#(This fails to ignore files without a ".", for example 
#'file.txt' works, but 
#'file' doesn't):
/*.*

#Only Include these specific directories and subdirectories:
!wordpress/
!wordpress/*/
!wordpress/*/wp-content/
!wordpress/*/wp-content/themes/

Notice how you have to explicitly allow content for each level you want to include. So if I have subdirectories 5 deep under themes, I still need to spell that out.

This is from @Yarin's comment here: https://stackoverflow.com/a/5250314/1696153

These were useful topics:

• How do negated patterns work in .gitignore?
• How do gitignore exclusion rules actually work?

I also tried

*
*/*
**/**

and **/wp-content/themes/**

or /wp-content/themes/**/*

None of that worked for me, either. Lots of trail and error!

Please forgive me

But I think a public open-source repository is a better way to share code and make contributions, and corrections, and additions like "I fixed this, I fixed that"

So I made a simple git-repository out of the topic-starter's code and all the additions:

https://github.com/jitbit/CsvExport

I also added a couple of useful fixes myself. Everyone could add suggestions, fork it to contribute etc. etc. etc. Send me your forks so I merge them back into the repo.

PS. I posted all copyright notices for Chris. @Chris if you're against this idea - let me know, I'll kill it.

When is scrolled to certain div, change your background color in jquery.

I found an important step to add to this - after you've installed the SDK, go to your project properties and change Configuration Properties->General->Platform Toolset from v100 or whatever it is to Windows7.1SDK. This changes $(WindowsSdkDir) to the proper place and seemed to solve some other difficulties I was encountering as well.

You have to execute your query and add single quote to $email in the query beacuse it's a string, and remove the is_resource($query) $query is a string, the $result will be the resource

$query = "SELECT `email` FROM `tblUser` WHERE `email` = '$email'";
$result = mysqli_query($link,$query); //$link is the connection

if(mysqli_num_rows($result) > 0 ){....}

UPDATE

Base in your edit just change:

if(is_resource($query) && mysqli_num_rows($query) > 0 ){
        $query = mysqli_fetch_assoc($query);
        echo $email . " email exists " .  $query["email"] . "\n";

By

if(is_resource($result) && mysqli_num_rows($result) == 1 ){
        $row = mysqli_fetch_assoc($result);
         echo $email . " email exists " .  $row["email"] . "\n";

and you will be fine

UPDATE 2

A better way should be have a Store Procedure that execute the following SQL passing the Email as Parameter

SELECT IF( EXISTS (
                  SELECT *
                  FROM `Table`
                  WHERE `email` = @Email)
          , 1, 0) as `Exist`

and retrieve the value in php

Pseudocodigo:

 $query = Call MYSQL_SP($EMAIL);
 $result = mysqli_query($conn,$query);
 $row = mysqli_fetch_array($result)
 $exist = ($row['Exist']==1)? 'the email exist' : 'the email doesnt exist';

if not exists (select * from sysobjects where name='cars' and xtype='U')
    create table cars (
        Name varchar(64) not null
    )
go

The above will create a table called cars if the table does not already exist.

The actual walk through the directories works as you have coded it. If you replace the contents of the inner loop with a simple print statement you can see that each file is found:

import os
rootdir = 'C:/Users/sid/Desktop/test'

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        print os.path.join(subdir, file)

If you still get errors when running the above, please provide the error message.

Updated for Python3

import os
rootdir = 'C:/Users/sid/Desktop/test'

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        print(os.path.join(subdir, file))

The proper way to initialize a multidimensional array in C or C++ is

int arr[2][5] = {{1,8,12,20,25}, {5,9,13,24,26}};

You can use this same trick to initialize even higher-dimensional arrays if you want.

Also, be careful in your initial code - you were trying to use 1-indexed offsets into the array to initialize it. This didn't compile, but if it did it would cause problems because C arrays are 0-indexed!

No way to do this that I know of, although I'm very curious to read if anyone has a good answer. I have been thinking about adding something like this to one of the apps my company builds, but have found no good way to do it.

The one thing I can think of (although not directly on point) is that I believe you can limit the total memory usage for a COM+ application in Windows. It would require the app to be written to run in COM+, of course, but it's the closest way I know of.

The working set stuff is good (Job Objects also control working sets), but that's not total memory usage, only real memory usage (paged in) at any one time. It may work for what you want, but afaik it doesn't limit total allocated memory.

UPDATE: for your updated question

variable.match(/\[[0-9]+\]/);

Try this:

variable.match(/[0-9]+/);    // for unsigned integers
variable.match(/[-0-9]+/);   // for signed integers
variable.match(/[-.0-9]+/);  // for signed float numbers

Hope this helps!

in my case: make sure not exist any form element in your page other than top main form, this cause events not fired

well, according to http://docs.python.org/tutorial/controlflow.html

It is not safe to modify the sequence being iterated over in the loop (this can only happen for mutable sequence types, such as lists). If you need to modify the list you are iterating over (for example, to duplicate selected items) you must iterate over a copy.

Ive modifiet Lukas Knuth's solution a little:

1) There's no need to subclass the webview,

2) the code will crash during bytecode verification on some Android 1.6 devices if you don't put nonexistant methods in seperate classes

3) Zoom controls will still appear if the user scrolls up/down a page. I simply set the zoom controller container to visibility GONE

  wv.getSettings().setSupportZoom(true);
  wv.getSettings().setBuiltInZoomControls(true);
  if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
    // Use the API 11+ calls to disable the controls
    // Use a seperate class to obtain 1.6 compatibility
    new Runnable() {
      public void run() {
        wv.getSettings().setDisplayZoomControls(false);
      }
    }.run();
  } else {
    final ZoomButtonsController zoom_controll =
        (ZoomButtonsController) wv.getClass().getMethod("getZoomButtonsController").invoke(wv, null);
    zoom_controll.getContainer().setVisibility(View.GONE);
  }

The answer anhic gave can be very inefficient if you have a large database and the attribute name is present only in some of the documents.

To improve efficiency you can add a $match to the aggregation.

db.collection.aggregate(
    {"$match": {"name" :{ "$ne" : null } } }, 
    {"$group" : {"_id": "$name", "count": { "$sum": 1 } } },
    {"$match": {"count" : {"$gt": 1} } }, 
    {"$project": {"name" : "$_id", "_id" : 0} }
)

Use: Path.GetFileName Method

var onlyFileName = System.IO.Path.GetFileName(ofd.FileName);

Use Range("A1").Text instead of .Value

post comment edit:
Why?
Because the .Text property of Range object returns what is literally visible in the spreadsheet, so if you cell displays for example i100l:25he*_92 then <- Text will return exactly what it in the cell including any formatting.
The .Value and .Value2 properties return what's stored in the cell under the hood excluding formatting. Specially .Value2 for date types, it will return the decimal representation.

If you want to dig deeper into the meaning and performance, I just found this article which seems like a good guide

another edit
Here you go @Santosh
type in (MANUALLY) the values from the DEFAULT (col A) to other columns
Do not format column A at all
Format column B as Text
Format column C as Date[dd/mm/yyyy]
Format column D as Percentage

now,
paste this code in a module

Sub main()

    Dim ws As Worksheet, i&, j&
    Set ws = Sheets(1)
    For i = 3 To 7
        For j = 1 To 4
            Debug.Print _
                    "row " & i & vbTab & vbTab & _
                    Cells(i, j).Text & vbTab & _
                    Cells(i, j).Value & vbTab & _
                    Cells(i, j).Value2
        Next j
    Next i
End Sub

and Analyse the output! Its really easy and there isn't much more i can do to help :)

            .TEXT              .VALUE             .VALUE2

By using transform: works like a charm!

<div class="parent">
    <span>center content using transform</span>
    </div>

    //CSS
    .parent {
        position: relative;
        height: 200px;
        border: 1px solid;
    }
    .parent span {
        position: absolute;
        top: 50%;
        left: 50%;
        -webkit-transform: translate(-50%, -50%);
        transform: translate(-50%, -50%);
    }

This thread caught my attention since it deals with a simple problem that requires a lot of work (CPU cycles) even for a modern CPU. And one day I also stood there with the same ¤#%"#" problem. I had to flip millions of bytes. However I know all my target systems are modern Intel-based so let's start optimizing to the extreme!!!

So I used Matt J's lookup code as the base. the system I'm benchmarking on is a i7 haswell 4700eq.

Matt J's lookup bitflipping 400 000 000 bytes: Around 0.272 seconds.

I then went ahead and tried to see if Intel's ISPC compiler could vectorise the arithmetics in the reverse.c.

I'm not going to bore you with my findings here since I tried a lot to help the compiler find stuff, anyhow I ended up with performance of around 0.15 seconds to bitflip 400 000 000 bytes. It's a great reduction but for my application that's still way way too slow..

So people let me present the fastest Intel based bitflipper in the world. Clocked at:

Time to bitflip 400000000 bytes: 0.050082 seconds !!!!!

Here is the workhorse:

bits 64
global bitflipbyte

bitflipbyte:    
        vmovdqa     ymm2, [rdx]
        add         rdx, 20h
        vmovdqa     ymm3, [rdx]
        add         rdx, 20h
        vmovdqa     ymm4, [rdx]
bitflipp_loop:
        vmovdqa     ymm0, [rdi] 
        vpand       ymm1, ymm2, ymm0 
        vpandn      ymm0, ymm2, ymm0 
        vpsrld      ymm0, ymm0, 4h 
        vpshufb     ymm1, ymm4, ymm1 
        vpshufb     ymm0, ymm3, ymm0         
        vpor        ymm0, ymm0, ymm1
        vmovdqa     [rdi], ymm0
        add     rdi, 20h
        dec     rsi
        jnz     bitflipp_loop
        ret

The code takes 32 bytes then masks out the nibbles. The high nibble gets shifted right by 4. Then I use vpshufb and ymm4 / ymm3 as lookup tables. I could use a single lookup table but then I would have to shift left before ORing the nibbles together again.

There are even faster ways of flipping the bits. But I'm bound to single thread and CPU so this was the fastest I could achieve. Can you make a faster version?

Please make no comments about using the Intel C/C++ Compiler Intrinsic Equivalent commands...

I had a problem because of markup.

HTML:

<div class="myclass">
 <div class="inner">

  <div class="myclass">
   <a href="#">Click Me</a>
  </div>

 </div>
</div>

jQuery

$('.myclass').on('click', 'a', function(event) { ... } );

You notice I have the same class 'myclass' twice in html, so it calls click for each instance of div.

Yes you can!

As of November 2016, Microsoft now has integrated .NET Core in it's official .NET Site

You can use the ThenBy and ThenByDescending extension methods:

foobarList.OrderBy(x => x.Foo).ThenBy( x => x.Bar)

This solution without timeouts! Real force redraw! For Android and iOS.

var forceRedraw = function(element){
  var disp = element.style.display;
  element.style.display = 'none';
  var trick = element.offsetHeight;
  element.style.display = disp;
};

You should apply a "clearfix" to clear the parent element. Next thing, the h4 for the header title, extend all the way across the header, so after you apply clearfix, it will push down the child element causing the header div to have a larger height.

Here is a fix, just replace it with your code.

  <div class="panel-heading clearfix">
     <b>Panel header</b>
       <div class="btn-group pull-right">
        <a href="#" class="btn btn-default btn-sm">## Lock</a>
        <a href="#" class="btn btn-default btn-sm">## Delete</a>
        <a href="#" class="btn btn-default btn-sm">## Move</a>
      </div>
   </div>

Editted on 12/22/2015 - added .clearfix to heading div

For a project hosted on GitHub, here's what people usually do:

  laike9m/
    myproject/
      mylib/
        mylib.go

git-credential-osxkeychain stores passwords in the Apple Keychain, as noted above.

By default, gitcredentials only considers the domain name. If you want Git to consider the full path (e.g. if you have multiple GitHub accounts), set the useHttpPath variable to true, as described at http://git-scm.com/docs/gitcredentials.html. Note that changing this setting will ask your credentials again for each URL.

you just cant do alert() in onbeforeunload, anything else works

Here's my approach, cut and split:

string cut (string& str, const string& del)
{
    string f = str;

    if (in.find_first_of(del) != string::npos)
    {
        f = str.substr(0,str.find_first_of(del));
        str = str.substr(str.find_first_of(del)+del.length());
    }

    return f;
}

vector<string> split (const string& in, const string& del=" ")
{
    vector<string> out();
    string t = in;

    while (t.length() > del.length())
        out.push_back(cut(t,del));

    return out;
}

BTW, if there's something I can do to optimize this ..

 setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

You can pass a format string to the ToString method, like so:

ToString("N4"); // 4 decimal points Number

DAO is native to Access and by far the best for general use. ADO has its place, but it is unlikely that this is it.

 Dim rs As DAO.Recordset
 Dim db As Database
 Dim strSQL as String

 Set db=CurrentDB

 strSQL = "select * from table where some condition"

 Set rs = db.OpenRecordset(strSQL)

 Do While Not rs.EOF

    rs.Edit
    rs!SomeField = "Abc"
    rs!OtherField = 2
    rs!ADate = Date()
    rs.Update

    rs.MoveNext
Loop

You're close. The parameters dictionary formatting doesn't look correct. You should try the following:

let parameters: [String: AnyObject] = [
    "IdQuiz" : 102,
    "IdUser" : "iosclient",
    "User" : "iosclient",
    "List": [
        [
            "IdQuestion" : 5,
            "IdProposition": 2,
            "Time" : 32
        ],
        [
            "IdQuestion" : 4,
            "IdProposition": 3,
            "Time" : 9
        ]
    ]
]

Just want to add a bit here to above explanations in the above answers. Which will save time for others as well.

In my case this method didn't returned any mobile number, an empty string was returned. It was due to the case that I had ported my number on the new sim. So if I go into the Settings>About Phone>Status>My Phone Number it shows me "Unknown".

git isn't a centralized scm like svn so you have two options:

• Use the web interface of target platforms (f.e. GitHub REST API or GitLab REST API)
• Download the repository and display logs locally

It may be annoying to implement for many different platforms (GitHub, GitLab, BitBucket, SourceForge, Launchpad, Gogs, ...) but fetching data is pretty slow (we talk about seconds) - no solution is perfect.

An example with fetching into a temporary directory:

git clone https://github.com/rust-lang/rust.git -b master --depth 3 --bare --filter=blob:none -q .
git log -n 3 --no-decorate --format=oneline

Alternatively:

git init --bare -q
git remote add -t master origin https://github.com/rust-lang/rust.git
git fetch --depth 3 --filter=blob:none -q
git log -n 3 --no-decorate --format=oneline origin/master

Both are optimized for performance by restricting to exactly 3 commits of one branch into a minimal local copy without file contents and preventing console outputs. Though opening a connection and calculating deltas during fetch takes some time.

An example with GitHub:

GET https://api.github.com/repos/rust-lang/rust/commits?sha=master&per_page=3

An example with GitLab:

GET https://gitlab.com/api/v4/projects/inkscape%2Finkscape/repository/commits?ref_name=master&per_page=3

Both are really fast but have different interfaces (like every platform).

Not having a compiler by me right now, I'll answer by asking a question:

Have you tried this? Does it work?

long key = -1L;
PreparedStatement statement = connection.prepareStatement();
statement.executeUpdate(YOUR_SQL_HERE, PreparedStatement.RETURN_GENERATED_KEYS);
ResultSet rs = statement.getGeneratedKeys();
if (rs != null && rs.next()) {
    key = rs.getLong(1);
}

Disclaimer: Obviously, I haven't compiled this, but you get the idea.

PreparedStatement is a subinterface of Statement, so I don't see a reason why this wouldn't work, unless some JDBC drivers are buggy.

Assembly assembly = Assembly.LoadFrom("MyAssembly.dll");

You can use @BeforeClass annotation to assure that setup() is always called first. Similarly, you can use @AfterClass annotation to assure that tearDown() is always called last.

This is usually not recommended, but it is supported.

It's not exactly what you want - but it'll essentially keep your DB connection open the entire time your tests are running, and then close it once and for all at the end.

I had a similar issue with django 3.0, according migrations section in the official documentation, running this was enough to update my table structure:

python manage.py makemigrations
python manage.py migrate

But the output was always the same: 'no change detected' about my models after I executed 'makemigrations' script. I had a syntax error on models.py at the model I wanted to update on db:

field_model : models.CharField(max_length=255, ...)

instead of:

field_model = models.CharField(max_length=255, ...)

Solving this stupid mistake, with those command the migration was done without problems. Maybe this helps someone.

My fix was apt install python3-dev

I find it very useful to append both stdout and stderr to a log file. I was glad to see a solution by alfonx with exec > >(tee -a), because I was wondering how to accomplish this using exec. I came across a creative solution using here-doc syntax and .: https://unix.stackexchange.com/questions/80707/how-to-output-text-to-both-screen-and-file-inside-a-shell-script

I discovered that in zsh, the here-doc solution can be modified using the "multios" construct to copy output to both stdout/stderr and the log file:

#!/bin/zsh
LOG=$0.log
# 8 is an arbitrary number;
# multiple redirects for the same file descriptor 
# triggers "multios"
. 8<<\EOF /dev/fd/8 2>&2 >&1 2>>$LOG >>$LOG
# some commands
date >&2
set -x
echo hi
echo bye
EOF
echo not logged

It is not as readable as the exec solution but it has the advantage of allowing you to log just part of the script. Of course, if you omit the EOF then the whole script is executed with logging. I'm not sure how zsh implements multios, but it may have less overhead than tee. Unfortunately it seems that one cannot use multios with exec.

You should use a callback parameter:

function Typer(callback)
{
    var srcText = 'EXAMPLE ';
    var i = 0;
    var result = srcText[i];
    var interval = setInterval(function() {
        if(i == srcText.length - 1) {
            clearInterval(interval);
            callback();
            return;
        }
        i++;
        result += srcText[i].replace("\n", "<br />");
        $("#message").html(result);
    },
    100);
    return true;


}

function playBGM () {
    alert("Play BGM function");
    $('#bgm').get(0).play();
}

Typer(function () {
    playBGM();
});

// or one-liner: Typer(playBGM);

So, you pass a function as parameter (callback) that will be called in that if before return.

Also, this is a good article about callbacks.

    var srcText = 'EXAMPLE ';_x000D_

I guess your elements on the page messes up because you don't clear out your floats, check this out

Demo

HTML

<div class="wrap">
    <div class="floatleft"></div>
    <div class="floatright"></div>
    <div style="clear: both;"></div>
</div>

CSS

.wrap {
    width: 100%;
}

.floatleft {
    float:left; 
    width: 80%;
    background-color: #ff0000;
    height: 400px;

}

If you use webpack project, after

npm install material-design-icons --save

you just need to

import materialIcons from 'material-design-icons/iconfont/material-icons.css'

Just to compliment the already given answers, see the following example:

$today = new DateTime('');
$expireDate = new DateTime($row->expireDate); //from database



if($today->format("Y-m-d") < $expireDate->format("Y-m-d")) { 
    //do something; 
}

Update: Or simple use old-school date() function:

if(date('Y-m-d') < date('Y-m-d', strtotime($expire_date))){
    //echo not yet expired! 
}   

The way you do it is pretty standard. You can define a utility clamp function:

/**
 * Returns a number whose value is limited to the given range.
 *
 * Example: limit the output of this computation to between 0 and 255
 * (x * 255).clamp(0, 255)
 *
 * @param {Number} min The lower boundary of the output range
 * @param {Number} max The upper boundary of the output range
 * @returns A number in the range [min, max]
 * @type Number
 */
Number.prototype.clamp = function(min, max) {
  return Math.min(Math.max(this, min), max);
};

(Although extending language built-ins is generally frowned upon)

If you are using Eclipse you can move files to and from the SD Card through the Android Perspective (it is called DDMS in Eclipse). Just select the Emulator in the left part of the screen and then choose the File Explorer tab. Above the list with your files should be two symbols, one with an arrow pointing at a phone, clicking this will allow you to choose a file to move to phone memory.

Try rename command:

rename 's/_h.png/_half.png/' *.png

Update:

example usage:

create some content

$ mkdir /tmp/foo
$ cd /tmp/foo
$ touch one_h.png two_h.png three_h.png
$ ls 
one_h.png  three_h.png  two_h.png

test solution:

$ rename 's/_h.png/_half.png/' *.png
$ ls
one_half.png  three_half.png  two_half.png

The best way to set/get the value of a textarea is the .val(), .value method.

.text() internally uses the .textContent (or .innerText for IE) method to get the contents of a <textarea>. The following test cases illustrate how text() and .val() relate to each other:

var t = '<textarea>';
console.log($(t).text('test').val());             // Prints test
console.log($(t).val('too').text('test').val());  // Prints too
console.log($(t).val('too').text());              // Prints nothing
console.log($(t).text('test').val('too').val());  // Prints too

console.log($(t).text('test').val('too').text()); // Prints test

The value property, used by .val() always shows the current visible value, whereas text()'s return value can be wrong.

You have to upgrade your subversion client to at least 1.7.

With the command line client, you have to manually upgrade your working copy format by issuing the command svn upgrade:

Upgrading the Working Copy

Subversion 1.7 introduces substantial changes to the working copy format. In previous releases of Subversion, Subversion would automatically update the working copy to the new format when a write operation was performed. Subversion 1.7, however, will make this a manual step. Before using Subversion 1.7 with their working copies, users will be required to run a new command, svn upgrade to update the metadata to the new format. This command may take a while, and for some users, it may be more practical to simply checkout a new working copy.
— Subversion 1.7 Release Notes

TortoiseSVN will perform the working copy upgrade with the next write operation:

Upgrading the Working Copy

Subversion 1.7 introduces substantial changes to the working copy format. In previous releases, Subversion would automatically update the working copy to the new format when a write operation was performed. Subversion 1.7, however, will make this a manual step.

Before you can use an existing working copy with TortoiseSVN 1.7, you have to upgrade the format first. If you right-click on an old working copy, TortoiseSVN only shows you one command in the context menu: Upgrade working copy.

You were just missing the second half of the column statement telling it to remove the entire column, since most normal Ranges start with a Column Letter, it was looking for a number and didn't get one. The ":" gets the whole column, or row.

I think what you were looking for in your Range was this:

Range("C:C,F:F,I:I,L:L,O:O,R:R").Delete

Just change the column letters to match your needs.

Related answer, but if you want to run clean up a user inputting values into a form, here's what you can do:

const numFormatter = new Intl.NumberFormat('en-US', {
  style: "decimal",
  maximumFractionDigits: 2
})

// Good Inputs
parseFloat(numFormatter.format('1234').replace(/,/g,"")) // 1234
parseFloat(numFormatter.format('123').replace(/,/g,"")) // 123

// 3rd decimal place rounds to nearest
parseFloat(numFormatter.format('1234.233').replace(/,/g,"")); // 1234.23
parseFloat(numFormatter.format('1234.239').replace(/,/g,"")); // 1234.24

// Bad Inputs
parseFloat(numFormatter.format('1234.233a').replace(/,/g,"")); // NaN
parseFloat(numFormatter.format('$1234.23').replace(/,/g,"")); // NaN

// Edge Cases
parseFloat(numFormatter.format(true).replace(/,/g,"")) // 1
parseFloat(numFormatter.format(false).replace(/,/g,"")) // 0
parseFloat(numFormatter.format(NaN).replace(/,/g,"")) // NaN

Use the international date local via format. This cleans up any bad inputs, if there is one it returns a string of NaN you can check for. There's no way currently of removing commas as part of the locale (as of 10/12/19), so you can use a regex command to remove commas using replace.

ParseFloat converts the this type definition from string to number

If you use React, this is what your calculate function could look like:

updateCalculationInput = (e) => {
    let value;
    value = numFormatter.format(e.target.value); // 123,456.78 - 3rd decimal rounds to nearest number as expected
    if(value === 'NaN') return; // locale returns string of NaN if fail
    value = value.replace(/,/g, ""); // remove commas
    value = parseFloat(value); // now parse to float should always be clean input

    // Do the actual math and setState calls here
}

While this seems to work

Code::query()
    ->where('to_be_used_by_user_id', '!=' , 2)
    ->orWhereNull('to_be_used_by_user_id')
    ->get();

you should not use it for big tables, because as a general rule "or" in your where clause is stopping query to use index. You are going from "Key lookup" to "full table scan"

Instead, try Union

$first = Code::whereNull('to_be_used_by_user_id');

$code = Code::where('to_be_used_by_user_id', '!=' , 2)
        ->union($first)
        ->get();

You can use set_include_path:

set_include_path('classes/');

Faced the same problem and solved it by editing my build.gradle file on the dependencies section, removing:

compile 'com.google.android.gms:play-services:7.8.0'

And replacing it with:

compile 'com.google.android.gms:play-services-location:7.8.0'
compile 'com.google.android.gms:play-services-analytics:7.8.0' 

you have to do like this in your project level gradle file

allprojects {
    repositories {
        jcenter()
        maven { url "http://dl.appnext.com/" }
        maven { url "https://maven.google.com" }
    }
}

The -i flag specifies the private key (.pem file) to use. If you don't specify that flag (as in your first command) it will use your default ssh key (usually under ~/.ssh/).

So in your first command, you are actually asking scp to upload the .pem file itself using your default ssh key. I don't think that is what you want.

Try instead with:

scp -r -i /Applications/XAMPP/htdocs/keypairfile.pem uploads/* ec2-user@publicdns:/var/www/html/uploads

This is the best way to detect Bearing from Location Object on Google Map:->

 float targetBearing=90;

      Location endingLocation=new Location("ending point"); 

      Location
       startingLocation=new Location("starting point");
       startingLocation.setLatitude(mGoogleMap.getCameraPosition().target.latitude);
       startingLocation.setLongitude(mGoogleMap.getCameraPosition().target.longitude);
       endingLocation.setLatitude(mLatLng.latitude);
       endingLocation.setLongitude(mLatLng.longitude);
      targetBearing =
       startingLocation.bearingTo(endingLocation);

Font myFont = new Font("Serif", Font.BOLD, 12);, then use a setFont method on your components like

JButton b = new JButton("Hello World");
b.setFont(myFont);

Seems you are using MSSQL, then, if I remember correctly, it is done like this:

UPDATE [Sales_Lead].[dbo].[Sales_Import] SET [AccountNumber] = 
RetrieveAccountNumber.AccountNumber 
FROM RetrieveAccountNumber 
WHERE [Sales_Lead].[dbo].[Sales_Import].LeadID = RetrieveAccountNumber.LeadID

no need for the padding or the corners.

here's a sample:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
    <gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
        android:angle="270"/>
</shape>

I had a very similar problem with a console program I develop under VS2010 (upgraded from VS2008 under XP) My prog uses EnLib to do some logging. The error was fired because EntLib had not the permission to register a new event source.

So I started once my compiled prog as an Administrator : it registered the event source. Then I went back developping and debugging from inside VS without problem.

If you have multiple markers you can use this simple solution to close a previously opened marker when clicking a new marker:

var infowindow = new google.maps.InfoWindow({
                maxWidth: (window.innerWidth - 160),
                content: content
            });

            marker.infowindow = infowindow;
            var openInfoWindow = '';

            marker.addListener('click', function (map, marker) {
                if (openInfoWindow) {
                    openInfoWindow.close();
                }
                openInfoWindow = this.infowindow;
                this.infowindow.open(map, this);
            });

Try creating another SQL view instead of a temporary table and then referencing it in the main SQL view. In other words, a view within a view. You can then drop the first view once you are done creating the main view.

Regex is a very bad choice for this kind of task. Try to find a web service or an address database or a product which can clean address data instead.

jQuery has a nice function for removing elements from the DOM.

The closest() function is cool because it will "get the first element that matches the selector by testing the element itself and traversing up through its ancestors."

$(this).closest("tr").remove();

Each delete button could run that very succinct code with a function call.

If you want it outside of loop then use the below code.

<?php
$author_id = get_post_field ('post_author', $cause_id);
$display_name = get_the_author_meta( 'display_name' , $author_id ); 
echo $display_name;
?>

The best solution is to override the click functionality:

public void _click(WebElement element){
    boolean flag = false;
    while(true) {
        try{
            element.click();
            flag=true;
        }
        catch (Exception e){
            flag = false;
        }
        if(flag)
        {
            try{
                element.click();
            }
            catch (Exception e){
                System.out.printf("Element: " +element+ " has beed clicked, Selenium exception triggered: " + e.getMessage());
            }
            break;
        }
    }
}

Why don't you use a for loop instead of using foreach. In this scenario, there is no way you can get the index of the current iteration of the foreach loop.

The name of the file can be added to the string[] in this way,

private string[] ColeccionDeCortes(string Path)
{
  DirectoryInfo X = new DirectoryInfo(Path);
  FileInfo[] listaDeArchivos = X.GetFiles();
  string[] Coleccion=new string[listaDeArchivos.Length];

  for (int i = 0; i < listaDeArchivos.Length; i++)
  {
     Coleccion[i] = listaDeArchivos[i].Name;
  }

  return Coleccion;
}

Both handlers get called.

You may be thinking of inline event binding (eg "onclick=..."), where a big drawback is only one handler may be set for an event.

jQuery conforms to the DOM Level 2 event registration model:

The DOM Event Model allows registration of multiple event listeners on a single EventTarget. To achieve this, event listeners are no longer stored as attribute values

v has 10 element, the index starts from 0 to 9.

for(int j=10;j>0;--j)
{
    cout<<v[j];   // v[10] out of range
}

you should update for loop to

for(int j=9; j>=0; --j)
//      ^^^^^^^^^^
{
    cout<<v[j];   // out of range
}

Or use reverse iterator to print element in reverse order

for (auto ri = v.rbegin(); ri != v.rend(); ++ri)
{
  std::cout << *ri << std::endl;
}

You can pass an ArrayList<E> the same way, if the E type is Serializable.

You would call the putExtra (String name, Serializable value) of Intent to store, and getSerializableExtra (String name) for retrieval.

Example:

ArrayList<String> myList = new ArrayList<String>();
intent.putExtra("mylist", myList);

In the other Activity:

ArrayList<String> myList = (ArrayList<String>) getIntent().getSerializableExtra("mylist");

Hidden layers are used in accordance with the complexity of our data. If we have input data which is linearly separable then we need not to use hidden layer e.g. OR gate but if we have a non linearly seperable data then we need to use hidden layer for example ExOR logical gate. Number of nodes taken at any layer depends upon the degree of cross validation of our output.

To change into another directory use WORKDIR. All the RUN, CMD and ENTRYPOINT commands after WORKDIR will be executed from that directory.

RUN make

The Selenium client bindings will try to locate the geckodriver executable from the system PATH. You will need to add the directory containing the executable to the system path.

• On Unix systems you can do the following to append it to your system’s search path, if you’re using a bash-compatible shell:

  export PATH=$PATH:/path/to/geckodriver
  

• On Windows you need to update the Path system variable to add the full directory path to the executable. The principle is the same as on Unix.

All below configuration for launching latest firefox using any programming language binding is applicable for Selenium2 to enable Marionette explicitly. With Selenium 3.0 and later, you shouldn't need to do anything to use Marionette, as it's enabled by default.

To use Marionette in your tests you will need to update your desired capabilities to use it.

Java :

As exception is clearly saying you need to download latest geckodriver.exe from here and set downloaded geckodriver.exe path where it's exists in your computer as system property with with variable webdriver.gecko.driver before initiating marionette driver and launching firefox as below :-

//if you didn't update the Path system variable to add the full directory path to the executable as above mentioned then doing this directly through code
System.setProperty("webdriver.gecko.driver", "path/to/geckodriver.exe");

//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new MarionetteDriver(capabilities); 

And for Selenium3 use as :-

WebDriver driver = new FirefoxDriver();

If you're still in trouble follow this link as well which would help you to solving your problem

.NET :

var driver = new FirefoxDriver(new FirefoxOptions());

Python :

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

# Path to Firefox DevEdition or Nightly.
# Firefox 47 (stable) is currently not supported,
# and may give you a suboptimal experience.
#
# On Mac OS you must point to the binary executable
# inside the application package, such as
# /Applications/FirefoxNightly.app/Contents/MacOS/firefox-bin
caps["binary"] = "/usr/bin/firefox"

driver = webdriver.Firefox(capabilities=caps)

Ruby :

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by directly passing marionette: true
# You might need to specify an alternate path for the desired version of Firefox

Selenium::WebDriver::Firefox::Binary.path = "/path/to/firefox"
driver = Selenium::WebDriver.for :firefox, marionette: true

JavaScript (Node.js) :

const webdriver = require('selenium-webdriver');
const Capabilities = require('selenium-webdriver/lib/capabilities').Capabilities;

var capabilities = Capabilities.firefox();

// Tell the Node.js bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.set('marionette', true);

var driver = new webdriver.Builder().withCapabilities(capabilities).build();

Using RemoteWebDriver

If you want to use RemoteWebDriver in any language, this will allow you to use Marionette in Selenium Grid.

Python:

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

driver = webdriver.Firefox(capabilities=caps)

Ruby :

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by using the Capabilities class
# You might need to specify an alternate path for the desired version of Firefox

caps = Selenium::WebDriver::Remote::Capabilities.firefox marionette: true, firefox_binary: "/path/to/firefox"
driver = Selenium::WebDriver.for :remote, desired_capabilities: caps

Java :

DesiredCapabilities capabilities = DesiredCapabilities.firefox();

// Tell the Java bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.setCapability("marionette", true);

WebDriver driver = new RemoteWebDriver(capabilities); 

.NET

DesiredCapabilities capabilities = DesiredCapabilities.Firefox();

// Tell the .NET bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.SetCapability("marionette", true);

var driver = new RemoteWebDriver(capabilities); 

Note : Just like the other drivers available to Selenium from other browser vendors, Mozilla has released now an executable that will run alongside the browser. Follow this for more details.

You can download latest geckodriver executable to support latest firefox from here

In order to generate release key hash you need to follow some easy steps.

1) Download Openssl

2) Make a openssl folder in C drive

3) Extract Zip files into this openssl folder created in C Drive.

4) Copy the File debug.keystore from .android folder in my case (C:\Users\SYSTEM.android) and paste into JDK bin Folder in my case (C:\Program Files\Java\jdk1.6.0_05\bin)

5) Open command prompt and give the path of JDK Bin folder in my case (C:\Program Files\Java\jdk1.7.0_40\bin).

6) Copy the following code and hit enter

keytool -exportcert -alias abcd-keystore D:\Projects\MyAppFolder\keystore.txt | C:\openssl\bin\openssl sha1 - binary | C:\openssl\bin\openssl base64 ex - keytool -exportcert -alias (your sing apk alias name enter here like my sign apk alian name is abcd )-keystore "signed apk generated keystore apth enter here" | "openssl bin folder path enter here" sha1 - binary | "openssl bin folder path enter here" base64

7) Now you need to enter password, Password = (enter your sign keystore password here)

8) you got keystore which are used for release app key hash

I guess you could use curl and wget, but since Oracle requires you to check of some checkmarks this will be painfull to emulate with the tools mentioned. You would have to download the page with the license agreement and from looking at it figure out what request is needed to get to the actual download.

Of course you could simply start a browser, but this might not qualify as 'from the command line'. So you might want to look into lynx, a text based browser.

I ended up doing the following and it works.

public static string Serialize(object obj)
{
    using (MemoryStream memoryStream = new MemoryStream())
    {
        DataContractSerializer serializer = new DataContractSerializer(obj.GetType());
        serializer.WriteObject(memoryStream, obj);
        return Encoding.UTF8.GetString(memoryStream.ToArray());
    }
}

public static object Deserialize(string xml, Type toType)
{
    using (MemoryStream memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(xml)))
    {
        XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(memoryStream, Encoding.UTF8, new XmlDictionaryReaderQuotas(), null);
        DataContractSerializer serializer = new DataContractSerializer(toType);
        return serializer.ReadObject(reader);
    }
}

It seems that the major problem was in the Serialize function when calling stream.GetBuffer(). Calling stream.ToArray() appears to work.

In case you want to be on the safe side, I recommend to use getopts.

Here is a small example:

    while getopts "x:c" opt; do
      case $opt in
        c)
          echo "-$opt was triggered, deploy to ci account" >&2
          DEPLOY_CI_ACCT="true"
          ;;
            x)
              echo "-$opt was triggered, Parameter: $OPTARG" >&2 
              CMD_TO_EXEC=${OPTARG}
              ;;
            \?)
              echo "Invalid option: -$OPTARG" >&2 
              Usage
              exit 1
              ;;
            :)
              echo "Option -$OPTARG requires an argument." >&2 
              Usage
              exit 1
              ;;
          esac
        done

see more details here for example http://wiki.bash-hackers.org/howto/getopts_tutorial

Assuming code.cpp is the source code, the following will not throw errors:

make code
./code

Here the first command compiles the code and creates an executable with the same name, and the second command runs it. There is no need to specify g++ keyword in this case.

In practical terms, boilerplate code is the stuff you cut-n-paste all over the place. Often it'll be things like a module header, plus some standard/required declarations (every module must declare a logger, every module must declare variables for its name and revision, etc.) On my current project, we're writing message handlers and they all have the same structure (read a message, validate it, process it) and to eliminate dependencies among the handlers we didn't want to have them all inherit from a base class, so we came up with a boilerplate skeleton. It declared all the routine variables, the standard methods, exception handling framework — all a developer had to do was add the code specific to the message being handled. It would have been quick & easy to use, but then we found out we were getting our message definitions in a spreadsheet (which used a boilerplate format), so we wound up just writing a code generator to emit 90% of the code (including the unit tests).

anyway it's too late but my solution was simple right-click on error-message in Eclipse and choosing Quick Fix >> Ignore for every pom with such errors

As mantioned by Jon Rimmer, you can use GitExtensions. GitExtensions does work in Visual Studio 2005 and Visual Studio 2008, it also does work in Visual Studio 2010 if you manually copy and config the .Addin file.

As of Room 1.1.0 you can use clearAllTables() which:

Deletes all rows from all the tables that are registered to this database as entities().

To select rows according to one 'cell_type' (e.g. 'hesc'), use ==:

expr[expr$cell_type == "hesc", ]

To select rows according to two or more different 'cell_type', (e.g. either 'hesc' or 'bj fibroblast'), use %in%:

expr[expr$cell_type %in% c("hesc", "bj fibroblast"), ]

In my case, the host was unkown and instead of typing yes to the question are you sure you want to continue connecting(yes/no/[fingerprint])? I was just hitting enter .

In my case, I just needed to close my pop-up and redirect the user to his profile page when he clicks "ok" after reading some message I tried with a few hacks, including setTimeout + self.close(), but with IE, this was closing the whole tab...

Solution : I replaced my link with a simple submit button.
<button type="submit" onclick="window.location.href='profile.html';">buttonText</button>. Nothing more.

This may sound stupid, but I didn't think to such a simple solution, since my pop-up did not have any form.

I hope it will help some front-end noobs like me !

disable button:

$('#button_id').attr('disabled','disabled');

enable button:

$('#button_id').removeAttr('disabled');

This would be another option:

$('.id_100 option[value=val2]').prop('selected', true);

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

could be generated from simple code:

import javax.swing.*;
import javax.swing.table.*;

public class TableCheckBox extends JFrame {

    private static final long serialVersionUID = 1L;
    private JTable table;

    public TableCheckBox() {
        Object[] columnNames = {"Type", "Company", "Shares", "Price", "Boolean"};
        Object[][] data = {
            {"Buy", "IBM", new Integer(1000), new Double(80.50), false},
            {"Sell", "MicroSoft", new Integer(2000), new Double(6.25), true},
            {"Sell", "Apple", new Integer(3000), new Double(7.35), true},
            {"Buy", "Nortel", new Integer(4000), new Double(20.00), false}
        };
        DefaultTableModel model = new DefaultTableModel(data, columnNames);
        table = new JTable(model) {

            private static final long serialVersionUID = 1L;

            /*@Override
            public Class getColumnClass(int column) {
            return getValueAt(0, column).getClass();
            }*/
            @Override
            public Class getColumnClass(int column) {
                switch (column) {
                    case 0:
                        return String.class;
                    case 1:
                        return String.class;
                    case 2:
                        return Integer.class;
                    case 3:
                        return Double.class;
                    default:
                        return Boolean.class;
                }
            }
        };
        table.setPreferredScrollableViewportSize(table.getPreferredSize());
        JScrollPane scrollPane = new JScrollPane(table);
        getContentPane().add(scrollPane);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                TableCheckBox frame = new TableCheckBox();
                frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
                frame.pack();
                frame.setLocation(150, 150);
                frame.setVisible(true);
            }
        });
    }
}

You're almost all the way there.

Your first few lines, comparing the last name, are right on track. The compareTo() method on string will return a negative number for a string in alphabetical order before, and a positive number for one in alphabetical order after.

Now, you just need to do the same thing for your first name and score.

In other words, if Last Name 1 == Last Name 2, go on a check your first name next. If the first name is the same, check your score next. (Think about nesting your if/then blocks.)

The solution above does not work in all InputBox-Cancel cases. Most notably, it does not work if you have to InputBox a Range.

For example, try the following InputBox for defining a custom range ('sRange', type:=8, requires Set + Application.InputBox) and you will get an error upon pressing Cancel:

Sub Cancel_Handler_WRONG()
Set sRange = Application.InputBox("Input custom range", _
    "Cancel-press test", Selection.Address, Type:=8)
If StrPtr(sRange) = 0 Then  'I also tried with sRange.address and vbNullString
    MsgBox ("Cancel pressed!")
    Exit Sub
End If
    MsgBox ("Your custom range is " & sRange.Address)
End Sub

The only thing that works, in this case, is an "On Error GoTo ErrorHandler" statement before the InputBox + ErrorHandler at the end:

Sub Cancel_Handler_OK()
On Error GoTo ErrorHandler
Set sRange = Application.InputBox("Input custom range", _
    "Cancel-press test", Selection.Address, Type:=8)
MsgBox ("Your custom range is " & sRange.Address)
Exit Sub
ErrorHandler:
    MsgBox ("Cancel pressed")
End Sub

So, the question is how to detect either an error or StrPtr()=0 with an If statement?

Use xpath more directly for both performance and clarity.

time_path <- "//start-valid-time"
temp_path <- "//temperature[@type='hourly']/value"

df <- data.frame(
    latitude=data[["number(//point/@latitude)"]],
    longitude=data[["number(//point/@longitude)"]],
    start_valid_time=sapply(data[time_path], xmlValue),
    hourly_temperature=as.integer(sapply(data[temp_path], as, "integer"))

leading to

> head(df, 2)
  latitude longitude          start_valid_time hourly_temperature
1    29.81    -82.42 2014-02-14T18:00:00-05:00                 60
2    29.81    -82.42 2014-02-14T19:00:00-05:00                 55

You can use Collections#sort to sort things alphabetically.

There is another way, though more for " How can I construct the following string in an Excel formula: "Maurice "The Rocket" Richard" " than " How to create strings containing double quotes in Excel formulas? ", which is simply to use two single quotes:

On the left is Calibri snipped from an Excel worksheet and on the right a snip from a VBA window. In my view escaping as mentioned by @YonahW wins 'hands down' but two single quotes is no more typing than two doubles and the difference is reasonably apparent in VBA without additional keystrokes while, potentially, not noticeable in a spreadsheet.

One more option is to ask MySQL for the query plan. This tells you two things:

• Whether there are any syntax errors in the query, if so the query plan command itself will fail
• How MySQL is planning to execute the query, e.g. what indexes it will use

In MySQL and most SQL databases the query plan command is describe, so you would do:

describe update ...;

<script>
    setTimeout(function(){
        window.location.href = 'form2.html';
    }, 5000);
</script>

And for home page add only '/'

<script>
    setTimeout(function(){
        window.location.href = '/';
    }, 5000);
</script>

You can't decrypt but you can BRUTEFORCE IT...

I.E: iterate a password list and check if one of them match with stored hash.

The only way that worked for me, is by copying the dll into your desktop or something, add reference to it, then delete the dll from your desktop. Visual Studio will refresh itself, and will finally reference the dll from the GAC on itself.

Here is a full example where the parent widget controls the children widget. The parent widget updates the children widgets (Text and TextField) with a counter.

To update the Text widget, all you do is pass in the String parameter. To update the TextField widget, you need to pass in a controller, and set the text in the controller.

main.dart:

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Demo',
      home: Home(),
    );
  }
}

class Home extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text('Update Text and TextField demo'),
        ),
        body: ParentWidget());
  }
}

class ParentWidget extends StatefulWidget {
  @override
  _ParentWidgetState createState() => _ParentWidgetState();
}

class _ParentWidgetState extends State<ParentWidget> {
  int _counter = 0;
  String _text = 'no taps yet';
  var _controller = TextEditingController(text: 'initial value');

  void _handleTap() {
    setState(() {
      _counter = _counter + 1;
      _text = 'number of taps: ' + _counter.toString();
      _controller.text  = 'number of taps: ' + _counter.toString();
    });
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      child: Column(children: <Widget>[
        RaisedButton(
          onPressed: _handleTap,
          child: const Text('Tap me', style: TextStyle(fontSize: 20)),
        ),
        Text('$_text'),
        TextField(controller: _controller,),
      ]),
    );
  }
}

Extension TabOut was the option i was looking for.

Use the splice method.

ArrayName.splice(indexValueOfArray,1);

This removes 1 item from the array starting at indexValueOfArray.

On Windows 7 one can just open the project folder and do a search for ".svn" if hidden files are enabled and delete all found .svn folders.

We had this exact error and it turned out to be an issue with the underlying HTTP implementation of NSURLRequest:

As far as we can tell, when iOS 8/9/10/11 receive an HTTP response with a Keep-Alive header, it keeps this connection to re-use later (as it should), but it keeps it for more than the timeout parameter of the Keep-Alive header (it seems to always keep the connection alive for 30 seconds.) Then when a second request is sent by the app less than 30 seconds later, it tries to re-use a connection that might have been dropped by the server (if more than the real Keep-Alive has elapsed).

Here are the solutions we have found so far:

• Increase the timeout parameter of the server above 30 seconds. It looks like iOS is always behaving as if the server will keep the connection open for 30 seconds regardless of the value provided in the Keep-Alive header. (This can be done for Apache by setting the KeepAliveTimeout option.
• You can simply disable the keep alive mechanism for iOS clients based on the User-Agent of your app (e.g. for Apache: BrowserMatch "iOS 8\." nokeepalive in the mod file setenvif.conf)
• If you don't have access to the server, you can try sending your requests with a Connection: close header: this will tell the server to drop the connection immediately and to respond without any keep alive headers. BUT at the moment, NSURLSession seems to override the Connection header when the requests are sent (we didn't test this solution extensively as we can tweak the Apache configuration)

    $sorter=array();
    $ret=array();
    reset($array);

    }
    asort($sorter);

SHOW TABLES only lists the non-TEMPORARY tables in a given database.

On Windows:

You can create a shortcut executing

Anaconda3\pythonw.exe Anaconda3\cwp.py Anaconda3\envs\<your_env> Anaconda3\envs\<your env>\pythonw.exe Anaconda3\envs\<your_env>\Scripts\spyder-script.py

However, if you started spyder from your venv inside Anaconda shell, it creates this shortcut for you automatically in the Windows menu. The steps:

1. install spyder in your venv using the methods mentioned in the other answers here.

2. (in anaconda:) activate testenv

3. Look up the windows menu "recently added" or just search for "spyder" in the windows menu, find spyder (testenv) and

• [add that to taskbar] and / or

• [look up the file source location] and copy that to your desktop, e.g. from C:\Users\USER\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Anaconda3 (64-bit), where the spyder links for any of my environments can be found.

Now you can directly start spyder from a shortcut without the need to open anaconda prompt.

It is possible, File > Save As

Have you tried to send your ajax request using POST method ? You could also try to set content type to 'text/x-json' while returning result from the server.
