This can be done in one simple line.

Swift 5

var my2DArray = (0..<4).map { _ in Array(0..<) }

You could also map it to instances of any class or struct of your choice

struct MyStructCouldBeAClass {
    var x: Int
    var y: Int
}

var my2DArray: [[MyStructCouldBeAClass]] = (0..<2).map { x in
    Array(0..<2).map { MyStructCouldBeAClass(x: x, y: $0)}
}

The fact that you're using a view model has no bearing. The standard way of using PagedList is to store "one page of items" as a ViewBag variable. All you have to determine is what collection constitutes what you'll be paging over. You can't logically page multiple collections at the same time, so assuming you chose Instructors:

ViewBag.OnePageOfItems = myViewModelInstance.Instructors.ToPagedList(pageNumber, 10);

Then, the rest of the standard code works as it always has.

You can use the df.reindex() function in pandas. df is

                      Net  Upper   Lower  Mid  Zsore
Answer option                                      
More than once a day  0%  0.22%  -0.12%    2     65
Once a day            0%  0.32%  -0.19%    3     45
Several times a week  2%  2.45%   1.10%    4     78
Once a week           1%  1.63%  -0.40%    6     65

define an list of column names

cols = df.columns.tolist()
cols
Out[13]: ['Net', 'Upper', 'Lower', 'Mid', 'Zsore']

move the column name to wherever you want

cols.insert(0, cols.pop(cols.index('Mid')))
cols
Out[16]: ['Mid', 'Net', 'Upper', 'Lower', 'Zsore']

then use df.reindex() function to reorder

df = df.reindex(columns= cols)

out put is: df

                      Mid  Upper   Lower Net  Zsore
Answer option

I find that if I specify .row:nth-of-type(..), my other row's elements (for other formatting, etc) also get alternating colours. So rather, I'd define in my css an entirely new class:

.row-striped:nth-of-type(odd){
  background-color: #efefef;
}

.row-striped:nth-of-type(even){
  background-color: #ffffff;
}

So now, the alternating row colours will only apply to the row container, when I specify its class as .row-striped, and not the elements inside the row.

<!-- this entire row container is #efefef -->
<div class="row row-striped">
    <div class="form-group">
        <div class="col-sm-8"><h5>Field Greens with strawberry vinegrette</h5></div>
        <div class="col-sm-4">
            <input type="number" type="number" step="1" min="0"></input><small>$30/salad</small>
        </div>
    </div>
</div>

<!-- this entire row container is #ffffff -->
<div class="row row-striped">
    <div class="form-group">
        <div class="col-sm-8"><h5>Greek Salad</h5></div>
        <div class="col-sm-4">
            <input type="number" type="number" step="1" min="0"></input><small>$25/salad</small>
        </div>
    </div>
</div>

The year() function just retrieves the year component of the underlying Date object, so it returns a number.

Calling format('YYYY') will invoke moment's string formatting functions, which will parse the format string supplied, and build a new string containing the appropriate data. Since you only are passing YYYY, then the result will be a string containing the year.

If all you need is the year, then use the year() function. It will be faster, as there is less work to do.

Do note that while years are the same in this regard, months are not! Calling format('M') will return months in the range 1-12. Calling month() will return months in the range 0-11. This is due to the same behavior of the underlying Date object.

Compare the length using lengthB and length function in oracle.

SELECT * FROM test WHERE length(sampletext) <> lengthb(sampletext)

{
  ...
  "scripts": {
    "start": "ENV NODE_ENV=production someapp --options"
  }
  ...
}

This error, in my case, preceded by syntax error at find method of a list in IE11. so replaced find method by filter method as suggested https://github.com/flrs/visavail/issues/19

then above controller not defined error resolved.

Your server tells you exactly what you need : [Hint: SSLProxyEngine]

You need to add that directive to your VirtualHost before the Proxy directives :

SSLProxyEngine on
ProxyPass /primary/store https://localhost:9763/store/
ProxyPassReverse /primary/store https://localhost:9763/store/

See the doc for more detail.

Just write the command "ping your server IP" without the double quote. save file name as filename.bat and then run the batch file as administrator

The order in which the classes appear in the html element does not matter, what counts is the order in which the blocks appear in the style sheet.

In your case .smallbox-paysummary is defined after .smallbox hence the 10px precedence.

Try first in Android Studio:

File -> Sync Project with Gradle Files

Only these 3 tags seem to be required (og:title, twitter:description, rel="icon"):

<meta property="og:title" content="San Roque 2014 Pollos" />

<meta name="twitter:description" property="og:description" itemprop="description" content="Programa de fiestas" />

<link rel="icon" type="image/png" href="https://images.weserv.nl/?url=http://pollosweb.wesped.es/programa_pollos/play.png&w=192&height=192" sizes="192x192" />

Experimenting / playing

The easiest way to experiment for me was with CodeSandbox following these steps:

• Create a Vanilla app with https://codesandbox.io/s/
• Modify your meta tags accordingly in the index.html file
• Save the file (ctrl+s) which would fork the app and generate its own unique url
• Paste that url in WhatsApp to see the preview (you don't even need to send a message)
• Make changes to the meta tags
• Modify the url - add a single character at the end of the url. This discards the "previous cached preview"

Quotes required

Just be sure to ALWAYS have quotes and closing quotes because WhatsApp is sensitive to that. Your above example does not have a closing quote for your og:description.

Here is the codepen demo showing the solution:

• Demo - Fill remaining vertical space with CSS using display:flex

Important highlights:

• all containers from html, body, ... .container, should have the height set to 100%
• introducing flex to ANY of the flex items will trigger calculation of the items sizes based on flex distribution:
  • if only one cell is set to flex, for example: flex: 1 then this flex item will occupy the remaining of the space
  • if there are more than one with the flex property, the calculation will be more complicated. For example, if the item 1 is set to flex: 1 and the item 2 is se to flex: 2 then the item 2 will take twice more of the remaining space
    • NOT TRUE: the item 2 will be twice larger than the item 1
    • check more about the concept of the remaining space: https://developer.mozilla.org/en-US/docs/Web/CSS/flex-grow
• Main Size Property
  • depends on the value of the flex-direction property
  • in our case height is just a preferred size
  • it will be overwritten in the presence of flex property: https://www.w3.org/TR/css-flexbox-1/#propdef-flex
    • When a box is a flex item, flex is consulted instead of the main size property to determine the main size of the box
  • min-* and max-* will be respected

Try the above answers 90% of the time this will be you issue. For me my problem was that my database password had a $ in it.

$servername = '127.0.0.1';
$username = 'user_bob';
$password = 'sdfasdf$B';

$conn = mysqli_connect($servername, $username, $password, 'any_database');

//DO NOT USE DOUBLE QUOTES;
//$password = "sdfasdf$B"; 

Download system image(of targeted android level of your project) from sdk manager for the project you have imported.

This error comes when you do not have target sdk of your android project installed in sdk folder

for eg. Your imported project's target sdk level may be android-19 and on sdk folder->system-images you may have android-21 installed. so you have to download android-19 system image and other files from sdk manager or you can copy paste it if you have the system image.

Supplementing the answer by p.s.w.g, here are three other ways of achieving this using lodash 4.17.5, without using _.includes():

Say you want to add object entry to an array of objects numbers, only if entry does not exist already.

let numbers = [
    { to: 1, from: 2 },
    { to: 3, from: 4 },
    { to: 5, from: 6 },
    { to: 7, from: 8 },
    { to: 1, from: 2 } // intentionally added duplicate
];

let entry = { to: 1, from: 2 };

/* 
 * 1. This will return the *index of the first* element that matches:
 */
_.findIndex(numbers, (o) => { return _.isMatch(o, entry) });
// output: 0


/* 
 * 2. This will return the entry that matches. Even if the entry exists
 *    multiple time, it is only returned once.
 */
_.find(numbers, (o) => { return _.isMatch(o, entry) });
// output: {to: 1, from: 2}


/* 
 * 3. This will return an array of objects containing all the matches.
 *    If an entry exists multiple times, if is returned multiple times.
 */
_.filter(numbers, _.matches(entry));
// output: [{to: 1, from: 2}, {to: 1, from: 2}]

If you want to return a Boolean, in the first case, you can check the index that is being returned:

_.findIndex(numbers, (o) => { return _.isMatch(o, entry) }) > -1;
// output: true

Swift 5.1

// Set NavigationBar Title Programmatically and Dynamic

Note : First add NavigationControllerItem to Your ViewController then goto their ViewController.swift file and Just Copy and Paste this in viewDidLoad().

navigationItem.title = "Your Title Here"

>>> log4j = sc._jvm.org.apache.log4j
>>> log4j.LogManager.getRootLogger().setLevel(log4j.Level.ERROR)

I tried many methods, but found this method is absolutely correct:

$window.location.reload();

Hope this help others stuck for days like me with version: angular 1.5.5, ionic 1.2.4, angular-ui-router 1.0.0

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)
plt.show()

This is a Task that is returning a Task of type String (C# anonymous function or in other word a delegation is used 'Func')

    public static async Task<string> MyTask()
    {
        //C# anonymous AsyncTask
        return await Task.FromResult<string>(((Func<string>)(() =>
        {
            // your code here
            return  "string result here";

        }))());
    }

The first value is the precision and the second is the scale, so 18,0 is essentially 18 digits with 0 digits after the decimal place. If you had 18,2 for example, you would have 18 digits, two of which would come after the decimal...

example of 18,2: 1234567890123456.12

There is no functional difference between numeric and decimal, other that the name and I think I recall that numeric came first, as in an earlier version.

And to answer, "can I add (-10) in that column?" - Yes, you can.

There are two options:

1. Create a php class file inside app/libraries/YourClassFile.php

   a. Any function you create in it would be easily accessible in all the views and controllers.

   b. If it is a static function you can easily access it by the class name.

   c. Make sure you inclued "app/libraries" in autoload classmap in composer file.

2. In app/config/app.php create a variable and you can reference the same using

   Config::get('variable_name');

Hope this helps.

Edit 1:

Example for my 1st point:

// app/libraries/DefaultFunctions.php

class DefaultFunctions{

    public static function getSomeValue(){
     // Fetch the Site Settings object
     $site_settings = Setting::all();
     return $site_settings; 
    }
}

//composer.json

"autoload": {
        "classmap": [
..
..
..  
        "app/libraries" // add the libraries to access globaly.
        ]
    }

 //YourController.php

   $default_functions  = new DefaultFunctions();
    $default_functions->getSomeValue();

I use select2 with ajax source with Laravel. In my case it simple work cycling option i receive from page and add Option to select2..

$filtri->stato = [1,2,...];

$('#stato') is my select2 with server side load

<script>
    @foreach ($filtri->stato as $item)
       $('#stato').append(new Option("{{\App\Models\stato::find($item)->nome}}",{{$item}}, false, true));
    @endforeach
</script>

In my case I can call text of option with find method, but it's possible do it with ajax call

Just adding an example that worked fine for me:

$sqldb = [string]($sqldir) + '\bin\MySQLInstanceConfig.exe'
$myarg = '-i ConnectionUsage=DSS Port=3311 ServiceName=MySQL RootPassword= ' + $rootpw
Start-Process $sqldb -ArgumentList $myarg

I used createdRow Function and solved my problem

    $('#result1').DataTable( {
        data: data['firstQuery'],
        columns: [
                        { title: 'Shipping Agent Code' },
                        { title: 'City' },
                        { title: 'Delivery Zone' },
                        { title: 'Total Slots Open ' },
                        { title: 'Slots Utilized' },
                        { title: 'Utilization %' },

                    ],
                    "columnDefs": [
                        {"className": "dt-center", "targets": "_all"}
                      ],
                      "createdRow": function( row, data, dataIndex){
                            if( data[5] >= 90  ){
                                $(row).css('background-color', '#F39B9B');
                            }
                            else if( data[5] <= 70  ){
                                $(row).css('background-color', '#A497E5');
                            }
                            else{
                                $(row).css('background-color', '#9EF395');
                            }

                        }
                } );

To use GPU from docker container, instead of using native Docker, use Nvidia-docker. To install Nvidia docker use following commands

curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey |  sudo apt-key add -
curl -s -L https://nvidia.github.io/nvidia-docker/ubuntu16.04/amd64/nvidia-
docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
sudo apt-get update
sudo apt-get install -y nvidia-docker
sudo pkill -SIGHUP dockerd # Restart Docker Engine
sudo nvidia-docker run --rm nvidia/cuda nvidia-smi # finally run nvidia-smi in the same container

Just by setting:

label.numberOfLines = 0

The label automatically adjusts its height based upon the amount of text entered.

downloaded Sql server management 2008 r2 and got it installed. Its getting installed but when I try to connect it via .\SQLEXPRESS it shows error. DO I need to install any SQL service on my system?

You installed management studio which is just a management interface to SQL Server. If you didn't (which is what it seems like) already have SQL Server installed, you'll need to install it in order to have it on your system and use it.

Swift 4.0

Store:

let arrayFruit = ["Apple","Banana","Orange","Grapes","Watermelon"]    

 //store in user default
 UserDefaults.standard.set(arrayFruit, forKey: "arrayFruit")

Fetch:

if let arr = UserDefaults.standard.array(forKey: "arrayFruit") as? [String]{
        print(arr)
    }

firstOrCreate() checks for all the arguments to be present before it finds a match.

If you only want to check on a specific field, then use firstOrCreate(['field_name' => 'value']) like

$user = User::firstOrCreate([
    'email' => '[email protected]'
], [
    'firstName' => 'abcd',
    'lastName' => 'efgh',
    'veristyName'=>'xyz',
]);

Then it check only the email

Try to open the Android Sdk manager and the path would be displayed on the status bar.

First I would like to thank Rose who was willing to help us, but your answer could solve the problem on a computer, but in others there was what was done could not always connect gets error 720. After much searching and contact the Microsoft support we can solve. In Device Manager, on the View menu, select to show hidden devices. Made it look for a remote Miniport IP or network monitor that is with warning of problems with the driver icon. In its properties in the details tab check the Key property of the driver. Look for this key in Regedit on Local Machine, make a backup of that key and delete it. Restart your windows. Reopen your device manager and select the miniport that had deleted the record. Activate the option to update the driver and look for the option driver on the computer manually and then use the option to locate the driver from the list available on the computer on the next screen uncheck show compatible hardware. Then you must select the Microsoft Vendor and the driver WAN Miniport the type that is changing, IP or IPV6 L2TP Network Monitor. After upgrading restart the computer.

I know it's a bit laborious but that was the only way that worked on all computers.

Different solution for those still having issues. Hopefully I can help those trying to reinstall Mysql. Note, It's a seek and destroy mission. So be weary. Assuming your root:

apt-get purge mysql*
apt-get purge dbconfig-common #the screen used for mysql password
find / -name *mysql*          #delete any traces of mysql
#insert apt-get cleanups, autoremove,updates etc.

Originally, something leftover was interfering with my startup of mysqlserver-5.5. These commands ended up resolving the issue for myself.

@RestController annotated classes are the same as @Controller but the @ResponseBody on the handler methods are implied.

In the initialization chunk I define a function

pagebreak <- function() {
  if(knitr::is_latex_output())
    return("\\newpage")
  else
    return('<div style="page-break-before: always;" />')
}

In the markdown part where I want to insert a page break, I type

`r pagebreak()`

If you want to make it shorter, you could write :

import matplolib.pyplot as plt
for i in range(4):
    plt.subplot(2,2,i+1).set_title('Subplot n°{}' .format(i+1))
plt.show()

It makes it maybe less clear but you don't need more lines or variables

You need to merge the remote branch into your current branch by running git pull.

If your local branch is already up-to-date, you may also need to run git pull --rebase.

A quick google search also turned up this same question asked by another SO user: Cannot push to GitHub - keeps saying need merge. More details there.

As per official documentation link shared by Andre Kirpitch, Oracle 10g gives a maximum size of 4000 bytes or characters for varchar2. If you are using a higher version of oracle (for example Oracle 12c), you can get a maximum size upto 32767 bytes or characters for varchar2. To utilize the extended datatype feature of oracle 12, you need to start oracle in upgrade mode. Follow the below steps in command prompt:

1) Login as sysdba (sqlplus / as sysdba)

2) SHUTDOWN IMMEDIATE;

3) STARTUP UPGRADE;

4) ALTER SYSTEM SET max_string_size=extended;

5) Oracle\product\12.1.0.2\rdbms\admin\utl32k.sql

6) SHUTDOWN IMMEDIATE;

7) STARTUP;

Upon investigation, it's also worth noting that when you want to start using docker in a new terminal window, the correct command is:

$(boot2docker shellinit)

I had tested these commands:

>>  docker info
Get http:///var/run/docker.sock/v1.15/info: dial unix /var/run/docker.sock: no such file or directory
>>  boot2docker shellinit
Writing /Users/ddavison/.boot2docker/certs/boot2docker-vm/ca.pem

    export DOCKER_TLS_VERIFY=1
>> docker info

Notice that docker info returned that same error. however.. when using $(boot2docker shellinit)...

You could use if type(ele) is dict or use isinstance(ele, dict) which would work if you had subclassed dict:

d = {'abc': 'abc', 'def': {'ghi': 'ghi', 'jkl': 'jkl'}}
for element in d.values():
    if isinstance(element, dict):
       for k, v in element.items():
           print(k,' ',v)

using LINQ and Lamba, i wanted to return two field values and assign it to single entity object field;

as Name = Fname + " " + LName;

See my below code which is working as expected; hope this is useful;

Myentity objMyEntity = new Myentity
{
id = obj.Id,
Name = contxt.Vendors.Where(v => v.PQS_ID == obj.Id).Select(v=> new { contact = v.Fname + " " + v.LName}).Single().contact
}

no need to declare the 'contact'

 /L*V "C:\Temp\msilog.log"= verbose logging at indicated path
 /QN = run completely silently
 /i = run install sequence 

The msiexec.exe command line is extensive with support for a variety of options. Here is another overview of the same command line interface. Here is an annotated versions (was broken, resurrected via way back machine).

It is also possible to make a batch file a lot shorter with constructs such as for loops as illustrated here for Windows Updates.

If there are check boxes that must be checked during the setup, you must find the appropriate PUBLIC PROPERTIES attached to the check box and set it at the command line like this:

msiexec.exe /i c:\setup.msi /QN /L*V "C:\Temp\msilog.log" STARTAPP=1 SHOWHELP=Yes

These properties are different in each MSI. You can find them via the verbose log file or by opening the MSI in Orca, or another appropriate tool. You must look either in the dialog control section or in the Property table for what the property name is. Try running the setup and create a verbose log file first and then search the log for messages ala "Setting property..." and then see what the property name is there. Then add this property with the value from the log file to the command line.

Using python-docx, as @Chinmoy Panda 's answer shows:

for para in doc.paragraphs:
    fullText.append(para.text)

However, para.text will lost the text in w:smarttag (Corresponding github issue is here: https://github.com/python-openxml/python-docx/issues/328), you should use the following function instead:

def para2text(p):
    rs = p._element.xpath('.//w:t')
    return u" ".join([r.text for r in rs])

For about 3 weeks, I faced the same problem.

After googling and trying and asking without solutions, I found that there was an Unknown Device called Android Composite ADB Interface in the Device Manager.

I had a look on this and finally resolved it by downloading the ADB Driver from here. (Maybe you need to troubleshoot your PC but the installer will tell you this.)

vw and vh stand for viewport width and viewport height respectively.

The difference between using width: 100vw instead of width: 100% is that while 100% will make the element fit all the space available, the viewport width has a specific measure, in this case the width of the available screen, including the document margin.

If you set the style body { margin: 0 }, 100vw should behave the same as 100%.

Additional notes

Using vw as unit for everything in your website, including font sizes and heights, will make it so that the site is always displayed proportionally to the device's screen width regardless of it's resolution. This makes it super easy to ensure your website is displayed properly in both workstation and mobile.

You can set font-size: 1vw (or whatever size suits your project) in your body CSS and everything specified in rem units will automatically scale according to the device screen, so it's easy to port existing projects and even frameworks (such as Bootstrap) to this concept.

According to Joshua Bloch (Effective Java), you should use private constructor which always throws exception. That will finally discourage user to create instance of util class.

Marking class abstract is not recommended because is abstract suggests reader that class is designed for inheritance.

func checkMaxLength(textField: UITextField!, maxLength: Int) {
        if (textField.text!.characters.count > maxLength) {
            textField.deleteBackward()
        }
}

a small change for IOS 9

I was having the same problem. When I initially created the java project in Eclipse I specified JRE 8. When I went into the project's build path and edited the JRE System Library, the Java 8 execution environment was selected. When I chose to use an "Alernate JRE" (still java 8) it fixed the error for me.

This only works when android:windowSoftInputMode of your activity is set to adjustResize in the manifest. You can use a layout listener to see if the root layout of your activity is resized by the keyboard.

I use something like the following base class for my activities:

public class BaseActivity extends Activity {
    private ViewTreeObserver.OnGlobalLayoutListener keyboardLayoutListener = new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            int heightDiff = rootLayout.getRootView().getHeight() - rootLayout.getHeight();
            int contentViewTop = getWindow().findViewById(Window.ID_ANDROID_CONTENT).getTop();

            LocalBroadcastManager broadcastManager = LocalBroadcastManager.getInstance(BaseActivity.this);

            if(heightDiff <= contentViewTop){
                onHideKeyboard();

                Intent intent = new Intent("KeyboardWillHide");
                broadcastManager.sendBroadcast(intent);
            } else {
                int keyboardHeight = heightDiff - contentViewTop;
                onShowKeyboard(keyboardHeight);

                Intent intent = new Intent("KeyboardWillShow");
                intent.putExtra("KeyboardHeight", keyboardHeight);
                broadcastManager.sendBroadcast(intent);
            }
        }
    };

    private boolean keyboardListenersAttached = false;
    private ViewGroup rootLayout;

    protected void onShowKeyboard(int keyboardHeight) {}
    protected void onHideKeyboard() {}

    protected void attachKeyboardListeners() {
        if (keyboardListenersAttached) {
            return;
        }

        rootLayout = (ViewGroup) findViewById(R.id.rootLayout);
        rootLayout.getViewTreeObserver().addOnGlobalLayoutListener(keyboardLayoutListener);

        keyboardListenersAttached = true;
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();

        if (keyboardListenersAttached) {
            rootLayout.getViewTreeObserver().removeGlobalOnLayoutListener(keyboardLayoutListener);
        }
    }
}

The following example activity uses this to hide a view when the keyboard is shown and show it again when the keyboard is hidden.

The xml layout:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/rootLayout"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:orientation="vertical">              

    <ScrollView
        android:id="@+id/scrollView"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        >

        <!-- omitted for brevity -->

    </ScrollView>

    <LinearLayout android:id="@+id/bottomContainer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        >

        <!-- omitted for brevity -->

    </LinearLayout>

</LinearLayout>

And the activity:

public class TestActivity extends BaseActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.test_activity);

        attachKeyboardListeners();
    }

    @Override
    protected void onShowKeyboard(int keyboardHeight) {
        // do things when keyboard is shown
        bottomContainer.setVisibility(View.GONE);
    }

    @Override
    protected void onHideKeyboard() {
        // do things when keyboard is hidden
        bottomContainer.setVisibility(View.VISIBLE);
    }        
}

I think you don't have the python-opencv package.

I had the exact same problem and

sudo apt-get install python-opencv

solved the issue for me.

you can install opencv from the following link https://www.learnopencv.com/install-opencv3-on-ubuntu/ It works for me . apt-get install doesnt contain many packages of opencv

You can solve that using display table.

Here is the updated JSFiddle that solves your problem.

CSS

.body {
    display: table;
    background-color: green;
}

.left-side {
    background-color: blue;
    float: none;
    display: table-cell;
    border: 1px solid;
}

.right-side {
    background-color: red;
    float: none;
    display: table-cell;
    border: 1px solid;
}

HTML

<div class="row body">
        <div class="col-xs-9 left-side">
            <p>sdfsdf</p>
            <p>sdfsdf</p>
            <p>sdfsdf</p>
            <p>sdfsdf</p>
            <p>sdfsdf</p>
            <p>sdfsdf</p>
        </div>
        <div class="col-xs-3 right-side">
            asdfdf
        </div>
    </div>

You need to get hold of the axes themselves. Probably the cleanest way is to change your last row:

lm = sns.lmplot('X','Y',df,col='Z',sharex=False,sharey=False)

Then you can get hold of the axes objects (an array of axes):

axes = lm.axes

After that you can tweak the axes properties

axes[0,0].set_ylim(0,)
axes[0,1].set_ylim(0,)

creates:

docker run -it --name NEW_NAME Existing_name

To change the existing image name.

You question is a bit unclear as to what you want, but judging from your comments, I assume you want each bubble to cover the screen, both vertically and horizontally. In that case, the vertical part is the tricky part.

As many others have answered, you first need to make sure that you are setting the viewport meta tag to trigger mobile devices to use their "ideal" viewport instead of the emulated "desktop width" viewport. The easiest and most fool proof version of this tag is as follows:

<meta name="viewport" content="width=device-width, initial-scale=1">

Source: PPK, probably the leading expert on how this stuff works. (See http://quirksmode.org/presentations/Spring2014/viewports_jqueryeu.pdf).

Essentially, the above makes sure that media queries and CSS measurements correspond to the ideal display of a virtual "point" on any given device — instead of shrinking pages to work with non-optimized desktop layouts. You don't need to understand the details of it, but it's important.

Now that we have a correct (non-faked) mobile viewport to work with, adjusting to the height of the viewport is still a tricky subject. Generally, web pages are fine to expand vertically, but not horizontally. So when you set height: 100% on something, that measurement has to relate to something else. At the topmost level, this is the size of the HTML element. But when the HTML element is taller than the screen (and expands to contain the contents), your measurements in percentages will be screwed up.

Enter the vh unit: it works like percentages, but works in relation to the viewport, not the containing block. MDN info page here: https://developer.mozilla.org/en-US/docs/Web/CSS/length#Viewport-percentage_lengths

Using that unit works just like you'd expect:

.bubble { height: 100vh; } /* be as tall as the viewport height. Done. */

It works on a lot of browsers (IE9 and up, modern Firefox, Safari, Chrome, Opera etc) but not all (support info here: http://caniuse.com/#search=vh). The downside in the browsers where it does work is that there is a massive bug in iOS6-7 that makes this technique unusable for this very case (details here: https://github.com/scottjehl/Device-Bugs/issues/36). It will be fixed in iOS8 though.

Depending on the HTML structure of your project, you may get away with using height: 100% on each element that is supposed to be as tall as the screen, as long as the following conditions are met:

1. The element is a direct child element of <body>.
2. Both the html and body elements have a 100% height set.

I have used that technique in the past, but it was long ago and I'm not sure it works on most mobile devices. Try it and see.

The next choice is to use a JavaScript helper to resize your elements to fit the viewport. Either a polyfill fixing the vh issues or something else altogether. Sadly, not every layout is doable in CSS.

I just wanted to chime in that I hit this after updating Android Studio components.

What worked for me was to open gradle-wrapper.properties and update the gradle version used. As of now for my projects the line reads:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.5-all.zip

This my actually working solution

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval"
    >
    <!-- The fill color -->
    <solid android:color="#ffff" />
    <!-- Just to add a border -->
    <stroke
        android:color="#8000"
        android:width="2dp"
    />
</shape>

Make sure your TextView width and height match (be the same in dp), if you want a perfect (unstretched) circle.

Make sure that the text fits into a circle, by either shortening your text OR enlarging your circle OR making your text size smaller OR reduce your padding/s, if any. OR a combination of the above suggestions.

[EDIT]

For what I can see in your pictures, you want to add too much text on a line, for pure circles.
Consider that the text should have a square aspect, so you can either wrap it (use \n) or just put the numbers inside the circles and put the writings above or uder the corresponding circle.

Easy

$('<img src=>')[0].src

Generates a img with empty src-name forces the browser to calculate the base-url by itself, no matter if you have /index.html or anything else.

You can use index arrays, simply pass your ind_pos as an index argument as below:

a = np.array([0,88,26,3,48,85,65,16,97,83,91])
ind_pos = np.array([1,5,7])

print(a[ind_pos])
# [88,85,16]

Index arrays do not necessarily have to be numpy arrays, they can be also be lists or any sequence-like object (though not tuples).

You can get current Playstore Version using JSoup with some modification like below:

@Override
protected String doInBackground(Void... voids) {

    String newVersion = null;
    try {
        newVersion = Jsoup.connect("https://play.google.com/store/apps/details?id=" + MainActivity.this.getPackageName() + "&hl=it")
                .timeout(30000)
                .userAgent("Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6")
                .referrer("http://www.google.com")
                .get()
                .select(".hAyfc .htlgb")
                .get(7)
                .ownText();
        return newVersion;
    } catch (Exception e) {
        return newVersion;
    }
}

@Override
protected void onPostExecute(String onlineVersion) {
    super.onPostExecute(onlineVersion);

    Log.d("update", "playstore version " + onlineVersion);
}

answer of @Tarun is not working anymore.

As explained above by @kris, depending on the region configurations of MS Excel it won't interpret the comma as the separator character. In my case I had to change it to semi-colon

For Eclipse Luna

Go to Help>Eclipse MarketPlace> Search for GlassFish Tools and install it.

Restart Eclipse.

Now go to servers>new>server and you will find Glassfish server.

In addition to the above configurations, I had to set deployment target to "Open Select Deployment Target Dialog", run once (choosing my device from the options listed), and from then on Android Studio was able to see my device even after changing the deployment setting back to "USB Device". My SWAG is that since Android Studio uses its own internal cache to find your device, it has to be initialized first.

in Appdelegate, put this code to see Document and Cache Dir:

#if TARGET_IPHONE_SIMULATOR
    NSLog(@"Documents Directory: %@", [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]);
    NSArray* cachePathArray = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
    NSString* cachePath = [cachePathArray lastObject];
    NSLog(@"Cache Directory: %@", cachePath);
#endif

on Log:

Here is the code for get value of checked radio button and set radio button checked according to it's value in edit form:

<p:commandXxx process> <p:ajax process> <f:ajax execute>

The process attribute is server side and can only affect UIComponents implementing EditableValueHolder (input fields) or ActionSource (command fields). The process attribute tells JSF, using a space-separated list of client IDs, which components exactly must be processed through the entire JSF lifecycle upon (partial) form submit.

JSF will then apply the request values (finding HTTP request parameter based on component's own client ID and then either setting it as submitted value in case of EditableValueHolder components or queueing a new ActionEvent in case of ActionSource components), perform conversion, validation and updating the model values (EditableValueHolder components only) and finally invoke the queued ActionEvent (ActionSource components only). JSF will skip processing of all other components which are not covered by process attribute. Also, components whose rendered attribute evaluates to false during apply request values phase will also be skipped as part of safeguard against tampered requests.

Note that it's in case of ActionSource components (such as <p:commandButton>) very important that you also include the component itself in the process attribute, particularly if you intend to invoke the action associated with the component. So the below example which intends to process only certain input component(s) when a certain command component is invoked ain't gonna work:

<p:inputText id="foo" value="#{bean.foo}" />
<p:commandButton process="foo" action="#{bean.action}" />

It would only process the #{bean.foo} and not the #{bean.action}. You'd need to include the command component itself as well:

<p:inputText id="foo" value="#{bean.foo}" />
<p:commandButton process="@this foo" action="#{bean.action}" />

Or, as you apparently found out, using @parent if they happen to be the only components having a common parent:

<p:panel><!-- Type doesn't matter, as long as it's a common parent. -->
    <p:inputText id="foo" value="#{bean.foo}" />
    <p:commandButton process="@parent" action="#{bean.action}" />
</p:panel>

Or, if they both happen to be the only components of the parent UIForm component, then you can also use @form:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" />
    <p:commandButton process="@form" action="#{bean.action}" />
</h:form>

This is sometimes undesirable if the form contains more input components which you'd like to skip in processing, more than often in cases when you'd like to update another input component(s) or some UI section based on the current input component in an ajax listener method. You namely don't want that validation errors on other input components are preventing the ajax listener method from being executed.

Then there's the @all. This has no special effect in process attribute, but only in update attribute. A process="@all" behaves exactly the same as process="@form". HTML doesn't support submitting multiple forms at once anyway.

There's by the way also a @none which may be useful in case you absolutely don't need to process anything, but only want to update some specific parts via update, particularly those sections whose content doesn't depend on submitted values or action listeners.

Noted should be that the process attribute has no influence on the HTTP request payload (the amount of request parameters). Meaning, the default HTML behavior of sending "everything" contained within the HTML representation of the <h:form> will be not be affected. In case you have a large form, and want to reduce the HTTP request payload to only these absolutely necessary in processing, i.e. only these covered by process attribute, then you can set the partialSubmit attribute in PrimeFaces Ajax components as in <p:commandXxx ... partialSubmit="true"> or <p:ajax ... partialSubmit="true">. You can also configure this 'globally' by editing web.xml and add

<context-param>
    <param-name>primefaces.SUBMIT</param-name>
    <param-value>partial</param-value>
</context-param>

Alternatively, you can also use <o:form> of OmniFaces 3.0+ which defaults to this behavior.

The standard JSF equivalent to the PrimeFaces specific process is execute from <f:ajax execute>. It behaves exactly the same except that it doesn't support a comma-separated string while the PrimeFaces one does (although I personally recommend to just stick to space-separated convention), nor the @parent keyword. Also, it may be useful to know that <p:commandXxx process> defaults to @form while <p:ajax process> and <f:ajax execute> defaults to @this. Finally, it's also useful to know that process supports the so-called "PrimeFaces Selectors", see also How do PrimeFaces Selectors as in update="@(.myClass)" work?

<p:commandXxx update> <p:ajax update> <f:ajax render>

The update attribute is client side and can affect the HTML representation of all UIComponents. The update attribute tells JavaScript (the one responsible for handling the ajax request/response), using a space-separated list of client IDs, which parts in the HTML DOM tree need to be updated as response to the form submit.

JSF will then prepare the right ajax response for that, containing only the requested parts to update. JSF will skip all other components which are not covered by update attribute in the ajax response, hereby keeping the response payload small. Also, components whose rendered attribute evaluates to false during render response phase will be skipped. Note that even though it would return true, JavaScript cannot update it in the HTML DOM tree if it was initially false. You'd need to wrap it or update its parent instead. See also Ajax update/render does not work on a component which has rendered attribute.

Usually, you'd like to update only the components which really need to be "refreshed" in the client side upon (partial) form submit. The example below updates the entire parent form via @form:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" required="true" />
    <p:message id="foo_m" for="foo" />
    <p:inputText id="bar" value="#{bean.bar}" required="true" />
    <p:message id="bar_m" for="bar" />
    <p:commandButton action="#{bean.action}" update="@form" />
</h:form>

(note that process attribute is omitted as that defaults to @form already)

Whilst that may work fine, the update of input and command components is in this particular example unnecessary. Unless you change the model values foo and bar inside action method (which would in turn be unintuitive in UX perspective), there's no point of updating them. The message components are the only which really need to be updated:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" required="true" />
    <p:message id="foo_m" for="foo" />
    <p:inputText id="bar" value="#{bean.bar}" required="true" />
    <p:message id="bar_m" for="bar" />
    <p:commandButton action="#{bean.action}" update="foo_m bar_m" />
</h:form>

However, that gets tedious when you have many of them. That's one of the reasons why PrimeFaces Selectors exist. Those message components have in the generated HTML output a common style class of ui-message, so the following should also do:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" required="true" />
    <p:message id="foo_m" for="foo" />
    <p:inputText id="bar" value="#{bean.bar}" required="true" />
    <p:message id="bar_m" for="bar" />
    <p:commandButton action="#{bean.action}" update="@(.ui-message)" />
</h:form>

(note that you should keep the IDs on message components, otherwise @(...) won't work! Again, see How do PrimeFaces Selectors as in update="@(.myClass)" work? for detail)

The @parent updates only the parent component, which thus covers the current component and all siblings and their children. This is more useful if you have separated the form in sane groups with each its own responsibility. The @this updates, obviously, only the current component. Normally, this is only necessary when you need to change one of the component's own HTML attributes in the action method. E.g.

<p:commandButton action="#{bean.action}" update="@this" 
    oncomplete="doSomething('#{bean.value}')" />

Imagine that the oncomplete needs to work with the value which is changed in action, then this construct wouldn't have worked if the component isn't updated, for the simple reason that oncomplete is part of generated HTML output (and thus all EL expressions in there are evaluated during render response).

The @all updates the entire document, which should be used with care. Normally, you'd like to use a true GET request for this instead by either a plain link (<a> or <h:link>) or a redirect-after-POST by ?faces-redirect=true or ExternalContext#redirect(). In effects, process="@form" update="@all" has exactly the same effect as a non-ajax (non-partial) submit. In my entire JSF career, the only sensible use case I encountered for @all is to display an error page in its entirety in case an exception occurs during an ajax request. See also What is the correct way to deal with JSF 2.0 exceptions for AJAXified components?

The standard JSF equivalent to the PrimeFaces specific update is render from <f:ajax render>. It behaves exactly the same except that it doesn't support a comma-separated string while the PrimeFaces one does (although I personally recommend to just stick to space-separated convention), nor the @parent keyword. Both update and render defaults to @none (which is, "nothing").

I had a similar problem running SciPy on my computer. There are two ways to fix this problem: 1. Yes you do need to cd into your python directory. 2. Sometimes you have to tell the computer explicitly what path to go through, you have to find the program you're using, open up the properties, and reroute the path it takes to run. 3. consult the manual: http://matplotlib.org/users/installing.html or http://www.scipy.org/install.html

the Scipy package is very finicky, and needs things spelled out in obnoxious detail.

For the legend, you can use this

plt.setp(g._legend.get_title(), fontsize=20)

Where g is your facetgrid object returned after you call the function making it.

The viewController has to be a child of UITabBarControllerDelegate. So you just need to add the following code on SWIFT 3

My guess is that ServiceUser.method() is itself transactional. It shouldn't be. Here's the reason why.

Here's what happens when a call is made to your ServiceUser.method() method:

1. the transactional interceptor intercepts the method call, and starts a transaction, because no transaction is already active
2. the method is called
3. the method calls MyService.doSth()
4. the transactional interceptor intercepts the method call, sees that a transaction is already active, and doesn't do anything
5. doSth() is executed and throws an exception
6. the transactional interceptor intercepts the exception, marks the transaction as rollbackOnly, and propagates the exception
7. ServiceUser.method() catches the exception and returns
8. the transactional interceptor, since it has started the transaction, tries to commit it. But Hibernate refuses to do it because the transaction is marked as rollbackOnly, so Hibernate throws an exception. The transaction interceptor signals it to the caller by throwing an exception wrapping the hibernate exception.

Now if ServiceUser.method() is not transactional, here's what happens:

1. the method is called
2. the method calls MyService.doSth()
3. the transactional interceptor intercepts the method call, sees that no transaction is already active, and thus starts a transaction
4. doSth() is executed and throws an exception
5. the transactional interceptor intercepts the exception. Since it has started the transaction, and since an exception has been thrown, it rollbacks the transaction, and propagates the exception
6. ServiceUser.method() catches the exception and returns

It seems the issue is in "-f ($_.Partition.Size/1GB)}}" If you want the value in MB then change the 1GB to 1MB.

Your server's response allows the request to include three specific non-simple headers:

Access-Control-Allow-Headers:origin, x-requested-with, content-type

but your request has a header not allowed by the server's response:

Access-Control-Request-Headers:access-control-allow-origin, content-type

All non-simple headers sent in a CORS request must be explicitly allowed by the Access-Control-Allow-Headers response header. The unnecessary Access-Control-Allow-Origin header sent in your request is not allowed by the server's CORS response. This is exactly what the "...not allowed by Access-Control-Allow-Headers" error message was trying to tell you.

There is no reason for the request to have this header: it does nothing, because Access-Control-Allow-Origin is a response header, not a request header.

Solution: Remove the setRequestHeader call that adds a Access-Control-Allow-Origin header to your request.

Basically VOLUME and -v option are almost equal. These mean 'mount specific directory on your container'. For example, VOLUME /data and -v /data is exactly same meaning. If you run the image that have VOLUME /data or with -v /data option, /data directory is mounted your container. This directory doesn't belong to your container.

Imagine that You add some files to /data on the container, then commit the container into new image. There isn't any files on data directory because mounted /data directory is belong to original container.

$ docker run -it -v /data --name volume ubuntu:14.04 bash
root@2b5e0f2d37cd:/# cd /data
root@2b5e0f2d37cd:/data# touch 1 2 3 4 5 6 7 8 9
root@2b5e0f2d37cd:/data# cd /tmp
root@2b5e0f2d37cd:/tmp# touch 1 2 3 4 5 6 7 8 9
root@2b5e0f2d37cd:/tmp# exit
exit

$ docker commit volume nacyot/volume  
835cfe3d8d159622507ba3256bb1c0b0d6e7c1419ae32751ad0f925c40378945
nacyot $ docker run -it nacyot/volume
root@dbe335c7e64d:/# cd /data
root@dbe335c7e64d:/data# ls
root@dbe335c7e64d:/data# cd /tmp
root@dbe335c7e64d:/tmp# ls
1  2  3  4  5  6  7  8  9
root@dbe335c7e64d:/tmp# 
root@dbe335c7e64d:/tmp# 

This mounted directory like /data is used to store data that is not belong to your application. And you can predefine the data directory that is not belong to the container by using VOLUME.

A difference between Volume and -v option is that you can use -v option dynamically on starting container. It mean you can mount some directory dynamically. And another difference is that you can mount your host directory on your container by using -v

Instead of using align-self: center use align-items: center.

There's no need to change flex-direction or use text-align.

Here's your code, with one adjustment, to make it all work:

ul {
  height: 100%;
}

li {
  display: flex;
  justify-content: center;
  /* align-self: center;    <---- REMOVE */
  align-items: center;   /* <---- NEW    */
  background: silver;
  width: 100%;
  height: 20%; 
}

The align-self property applies to flex items. Except your li is not a flex item because its parent – the ul – does not have display: flex or display: inline-flex applied.

Therefore, the ul is not a flex container, the li is not a flex item, and align-self has no effect.

The align-items property is similar to align-self, except it applies to flex containers.

Since the li is a flex container, align-items can be used to vertically center the child elements.

* {_x000D_
  padding: 0;_x000D_
  margin: 0;_x000D_
}_x000D_
html, body {_x000D_
  height: 100%;_x000D_
}_x000D_
ul {_x000D_
  height: 100%;_x000D_
}_x000D_
li {_x000D_
  display: flex;_x000D_
  justify-content: center;_x000D_
  /* align-self: center; */_x000D_
  align-items: center;_x000D_
  background: silver;_x000D_
  width: 100%;_x000D_
  height: 20%;_x000D_
}

<ul>_x000D_
  <li>This is the text</li>_x000D_
</ul>

codepen demo

Technically, here's how align-items and align-self work...

The align-items property (on the container) sets the default value of align-self (on the items). Therefore, align-items: center means all flex items will be set to align-self: center.

But you can override this default by adjusting the align-self on individual items.

For example, you may want equal height columns, so the container is set to align-items: stretch. However, one item must be pinned to the top, so it is set to align-self: flex-start.

example

How is the text a flex item?

Some people may be wondering how a run of text...

<li>This is the text</li>

is a child element of the li.

The reason is that text that is not explicitly wrapped by an inline-level element is algorithmically wrapped by an inline box. This makes it an anonymous inline element and child of the parent.

From the CSS spec:

9.2.2.1 Anonymous inline boxes

Any text that is directly contained inside a block container element must be treated as an anonymous inline element.

The flexbox specification provides for similar behavior.

4. Flex Items

Each in-flow child of a flex container becomes a flex item, and each contiguous run of text that is directly contained inside a flex container is wrapped in an anonymous flex item.

Hence, the text in the li is a flex item.

That header file is not part of the C++ standard, is therefore non-portable, and should be avoided.

Moreover, even if there were some catch-all header in the standard, you would want to avoid it in lieu of specific headers, since the compiler has to actually read in and parse every included header (including recursively included headers) every single time that translation unit is compiled.

Press Ctrl+,

Then you will see a docked window under name of "Go to all"

This a picture of the "Go to all" in my IDE

1. Click somewhere on the chart to select it.

2. You should now see 3 new tabs appear at the top of the screen called "Design", "Layout" and "Format".

3. Click on the "Design" tab.

4. There will be a button called "Switch Row/Column" within the "data" group, click it.

To be able to pass the select, I just set it back to :

  $('#selectID').prop('disabled',false);

or

  $('#selectID').attr('disabled',false);

when passing the request.

TL;DR

TEXT

• fixed max size of 65535 characters (you cannot limit the max size)
• takes 2 + c bytes of disk space, where c is the length of the stored string.
• cannot be (fully) part of an index. One would need to specify a prefix length.

VARCHAR(M)

• variable max size of M characters
• M needs to be between 1 and 65535
• takes 1 + c bytes (for M ≤ 255) or 2 + c (for 256 ≤ M ≤ 65535) bytes of disk space where c is the length of the stored string
• can be part of an index

More Details

TEXT has a fixed max size of 2¹6-1 = 65535 characters.
VARCHAR has a variable max size M up to M = 2¹6-1.
So you cannot choose the size of TEXT but you can for a VARCHAR.

The other difference is, that you cannot put an index (except for a fulltext index) on a TEXT column.
So if you want to have an index on the column, you have to use VARCHAR. But notice that the length of an index is also limited, so if your VARCHAR column is too long you have to use only the first few characters of the VARCHAR column in your index (See the documentation for CREATE INDEX).

But you also want to use VARCHAR, if you know that the maximum length of the possible input string is only M, e.g. a phone number or a name or something like this. Then you can use VARCHAR(30) instead of TINYTEXT or TEXT and if someone tries to save the text of all three "Lord of the Ring" books in your phone number column you only store the first 30 characters :)

Edit: If the text you want to store in the database is longer than 65535 characters, you have to choose MEDIUMTEXT or LONGTEXT, but be careful: MEDIUMTEXT stores strings up to 16 MB, LONGTEXT up to 4 GB. If you use LONGTEXT and get the data via PHP (at least if you use mysqli without store_result), you maybe get a memory allocation error, because PHP tries to allocate 4 GB of memory to be sure the whole string can be buffered. This maybe also happens in other languages than PHP.

However, you should always check the input (Is it too long? Does it contain strange code?) before storing it in the database.

Notice: For both types, the required disk space depends only on the length of the stored string and not on the maximum length.
E.g. if you use the charset latin1 and store the text "Test" in VARCHAR(30), VARCHAR(100) and TINYTEXT, it always requires 5 bytes (1 byte to store the length of the string and 1 byte for each character). If you store the same text in a VARCHAR(2000) or a TEXT column, it would also require the same space, but, in this case, it would be 6 bytes (2 bytes to store the string length and 1 byte for each character).

For more information have a look at the documentation.

Finally, I want to add a notice, that both, TEXT and VARCHAR are variable length data types, and so they most likely minimize the space you need to store the data. But this comes with a trade-off for performance. If you need better performance, you have to use a fixed length type like CHAR. You can read more about this here.

First import Corelocation and MapKit library:

import MapKit
import CoreLocation

inherit from CLLocationManagerDelegate to our class

class ViewController: UIViewController, CLLocationManagerDelegate

create a locationManager variable, this will be your location data

var locationManager = CLLocationManager()

create a function to get the location info, be specific this exact syntax works:

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

in your function create a constant for users current location

let userLocation:CLLocation = locations[0] as CLLocation // note that locations is same as the one in the function declaration  

stop updating location, this prevents your device from constantly changing the Window to center your location while moving (you can omit this if you want it to function otherwise)

manager.stopUpdatingLocation()

get users coordinate from userLocatin you just defined:

let coordinations = CLLocationCoordinate2D(latitude: userLocation.coordinate.latitude,longitude: userLocation.coordinate.longitude)

define how zoomed you want your map be:

let span = MKCoordinateSpanMake(0.2,0.2) combine this two to get region:

let region = MKCoordinateRegion(center: coordinations, span: span)//this basically tells your map where to look and where from what distance

now set the region and choose if you want it to go there with animation or not

mapView.setRegion(region, animated: true)

close your function }

from your button or another way you want to set the locationManagerDeleget to self

now allow the location to be shown

designate accuracy

locationManager.desiredAccuracy = kCLLocationAccuracyBest

authorize:

 locationManager.requestWhenInUseAuthorization()

to be able to authorize location service you need to add this two lines to your plist

get location:

locationManager.startUpdatingLocation()

show it to the user:

mapView.showsUserLocation = true

This is my complete code:

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    @IBOutlet weak var mapView: MKMapView!

    var locationManager = CLLocationManager()


    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    @IBAction func locateMe(sender: UIBarButtonItem) {
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestWhenInUseAuthorization()
        locationManager.startUpdatingLocation()

        mapView.showsUserLocation = true

    }

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        let userLocation:CLLocation = locations[0] as CLLocation

        manager.stopUpdatingLocation()

        let coordinations = CLLocationCoordinate2D(latitude: userLocation.coordinate.latitude,longitude: userLocation.coordinate.longitude)
        let span = MKCoordinateSpanMake(0.2,0.2)
        let region = MKCoordinateRegion(center: coordinations, span: span)

        mapView.setRegion(region, animated: true)

    }
}

This error is because print isn't a function in Python 2.6.

You can either define a helper UDF that performs the print, or use the __future__ library to treat print as a function:

>>> from operator import add
>>> f = sc.textFile("README.md")
>>> def g(x):
...     print x
...
>>> wc.foreach(g)

or

>>> from __future__ import print_function
>>> wc.foreach(print)

However, I think it would be better to use collect() to bring the RDD contents back to the driver, because foreach executes on the worker nodes and the outputs may not necessarily appear in your driver / shell (it probably will in local mode, but not when running on a cluster).

>>> for x in wc.collect():
...     print x

Try using the count function in dplyr:

library(dplyr)
dat1_frame %>% 
    count(MONTH.YEAR)

I am not sure how you got MONTH-YEAR as a variable name. My R version does not allow for such a variable name, so I replaced it with MONTH.YEAR.

As a side note, the mistake in your code was that dat1_frame %.% group_by(MONTH-YEAR) without a summarise function returns the original data frame without any modifications. So, you want to use

dat1_frame %>%
    group_by(MONTH.YEAR) %>%
    summarise(count=n())

Below is a simple function implementation which splits a DataFrame to chunks and a few code examples:

import pandas as pd

def split_dataframe_to_chunks(df, n):
    df_len = len(df)
    count = 0
    dfs = []

    while True:
        if count > df_len-1:
            break

        start = count
        count += n
        #print("%s : %s" % (start, count))
        dfs.append(df.iloc[start : count])
    return dfs


# Create a DataFrame with 10 rows
df = pd.DataFrame([i for i in range(10)])

# Split the DataFrame to chunks of maximum size 2
split_df_to_chunks_of_2 = split_dataframe_to_chunks(df, 2)
print([len(i) for i in split_df_to_chunks_of_2])
# prints: [2, 2, 2, 2, 2]

# Split the DataFrame to chunks of maximum size 3
split_df_to_chunks_of_3 = split_dataframe_to_chunks(df, 3)
print([len(i) for i in split_df_to_chunks_of_3])
# prints [3, 3, 3, 1]

In my case:

sudo -E add-apt-repository ppa:linuxuprising/java

sudo apt-get update

sudo apt install  oracle-java12-installer

that works fine

You can also create a new jsp file sayng that form is submited and in your main action file just write its file name

Eg. Your form is submited is in a file succes.jsp Then your action file will have

Request.sendRedirect("success.jsp")
