Programs & Examples On #Avaudiosession

Please note if you are downloading from the FTP to your local, you will need to use the following:

with open( filename, 'wb' ) as file :
        ftp.retrbinary('RETR %s' % filename, file.write)

Otherwise, the script will at your local file storage rather than the FTP.

I spent a few hours making the mistake myself.

Script below:

import ftplib

# Open the FTP connection
ftp = ftplib.FTP()
ftp.cwd('/where/files-are/located')


filenames = ftp.nlst()

for filename in filenames:

    with open( filename, 'wb' ) as file :
        ftp.retrbinary('RETR %s' % filename, file.write)

        file.close()

ftp.quit()

It don't create normally; you need to add it by yourself.

After adding Global.asax by

• Right clicking your website -> Add New Item -> Global Application Class -> Add

You need to add a class

• Right clicking App_Code -> Add New Item -> Class -> name it Global.cs -> Add

Inherit the newly generated by System.Web.HttpApplication and copy all the method created Global.asax to Global.cs and also add an inherit attribute to the Global.asax file.

Your Global.asax will look like this: -

<%@ Application Language="C#" Inherits="Global" %>

Your Global.cs in App_Code will look like this: -

public class Global : System.Web.HttpApplication
{
    public Global()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    void Application_Start(object sender, EventArgs e)
    {
        // Code that runs on application startup

    }
    /// Many other events like begin request...e.t.c, e.t.c
}

The error:

'int' object has no attribute '__getitem__'

means that you're attempting to apply the index operator [] on an int, not a list. So is col not a list, even when it should be? Let's start from that.

Look here:

col = [[0 for col in range(5)] for row in range(6)]

Use a different variable name inside, looks like the list comprehension overwrites the col variable during iteration. (Not during the iteration when you set col, but during the following ones.)

I have craeted a little script for read directory and write a console name new file (example: 'name.txt' ) and text into file.

const readline = require('readline');
const fs = require('fs');

const pathFile = fs.readdirSync('.');

const file = readline.createInterface({
  input: process.stdin,
  output: process.stdout
});

file.question('Insert name of your file? ', (f) => {
  console.log('File is: ',f.toString().trim());
  try{
    file.question('Insert text of your file? ', (d) => {
      console.log('Text is: ',d.toString().trim());
      try {
        if(f != ''){
          if (fs.existsSync(f)) {
            //file exists
            console.log('file exist');
            return file.close();
          }else{
            //save file
            fs.writeFile(f, d, (err) => {
                if (err) throw err;
                console.log('The file has been saved!');
                file.close();
            });
          }
        }else{
          //file empty 
          console.log('Not file is created!');
          console.log(pathFile);
          file.close();
        }
      } catch(err) {
        console.error(err);
        file.close();
      }
    });
  }catch(err){
    console.log(err);
    file.close();
  }
});

There is also a great ncdu utility - it can show directory size with detailed info about subfolders and files.

Installation

Ubuntu:

$ sudo apt-get install ncdu

Usage

Just type ncdu [path] in the command line. After a few seconds for analyzing the path, you will see something like this:

$ ncdu 1.11 ~ Use the arrow keys to navigate, press ? for help

According to the documentation.

you have to change permission on the mentioned path.

This type of warnings are usually flagged because of the request HTTP headers. Specifically the Accept request header. The MDN documentation for HTTP headers states

The Accept request HTTP header advertises which content types, expressed as MIME types, the client is able to understand. Using content negotiation, the server then selects one of the proposals, uses it and informs the client of its choice with the Content-Type response header. Browsers set adequate values for this header depending of the context where the request is done....

application/json is probably not on the list of MIME types in the Accept header sent by the browser hence the warning.

Solution

Custom HTTP headers can only be sent programmatically via XMLHttpRequest or any of the js library wrappers implementing it.

First of all open applicationhost.config file in visual studio. address>>C:\Users\Your User Name\Documents\IISExpress\config\applicationhost.config

Then find this codes:

<site name="Your Site_Name" id="24">
        <application path="/" applicationPool="Clr4IntegratedAppPool"
        <virtualDirectory path="/" physicalPath="C:\Users\Your User         Name\Documents\Visual Studio 2013\Projects\Your Site Name" />
        </application>
         <bindings>      
           <binding protocol="http" bindingInformation="*:Port_Number:*" />
         </bindings>
   </site>

*)Port_Number:While your site running in IIS express on your computer, port number will visible in address bar of your browser like this: localhost:port_number/... When edit this file save it.

In the Second step you must run cmd as administrator and type this code: netsh http add urlacl url=http://*:port_Number/ user=everyone and press enter

In Third step you must Enable port on firewall

Go to the “Control Panel\System and Security\Windows Firewall”

Click “Advanced settings”

Select “Inbound Rules”

Click on “New Rule …” button

Select “Port”, click “Next”

Fill your IIS Express listening port number, click “Next”

Select “Allow the connection”, click “Next”

Check where you would like allow connection to IIS Express (Domain,Private, Public), click “Next”

Fill rule name (e.g “IIS Express), click “Finish”

I hopeful this answer be useful for you

Update for Visual Studio 2015 in this link: https://johan.driessen.se/posts/Accessing-an-IIS-Express-site-from-a-remote-computer

input = InputBox("Text:")

If input <> "" Then
   ' Normal
Else
   ' Cancelled, or empty
End If

From MSDN:

If the user clicks Cancel, the function returns a zero-length string ("").

Creating an Empty Dataframe with known Column Name:

Names = ['Col1','ActivityID','TransactionID']
df = pd.DataFrame(columns = Names)

Creating a dataframe from csv:

df = pd.DataFrame('...../file_name.csv')

Creating a dynamic filter to subset a dtaframe:

i = 12
df[df['ActivitiID'] <= i]

Creating a dynamic filter to subset required columns of dtaframe

df[df['ActivityID'] == i][['TransactionID','ActivityID']]

I also had this problem recently. Working with a new client, trying to get a an old web forms app running from Visual Studio, with IISExpress using Windows Authentication. For me, the web.config was correctly configured

However, the IISExpress.config settings file had:

<windowsAuthentication enabled="false">

The user account the developer was logged in was very new, so unlikely it had been edited. Simple fix it turned out, change this to enabled=true and it all ran as it should then.

As @impulsgraw wrote. You need to check for undefined after the pipes:

<div ng-show="foo || undefined">
    Show this if foo is defined!
</div>
<div ng-show="boo || !undefined">
    Show this if boo is undefined!
</div>

The first one catches all subclasses of Throwable (this includes Exception and Error), the second one catches all subclasses of Exception.

Error is programmatically unrecoverable in any way and is usually not to be caught, except for logging purposes (which passes it through again). Exception is programmatically recoverable. Its subclass RuntimeException indicates a programming error and is usually not to be caught as well.

What you can do is use a pixmap as an icon and then put this icon onto the button.

To make sure the size of the button will be correct, you have to reisze the icon according to the pixmap size.

Something like this should work :

QPixmap pixmap("image_path");
QIcon ButtonIcon(pixmap);
button->setIcon(ButtonIcon);
button->setIconSize(pixmap.rect().size());

I'd rather not turn an integer into a string, so here's the function I use for this:

def digitize(n, base=10):
    if n == 0:
        yield 0
    while n:
        n, d = divmod(n, base)
        yield d

Examples:

tuple(digitize(123456789)) == (9, 8, 7, 6, 5, 4, 3, 2, 1)
tuple(digitize(0b1101110, 2)) == (0, 1, 1, 1, 0, 1, 1)
tuple(digitize(0x123456789ABCDEF, 16)) == (15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1)

As you can see, this will yield digits from right to left. If you'd like the digits from left to right, you'll need to create a sequence out of it, then reverse it:

reversed(tuple(digitize(x)))

You can also use this function for base conversion as you split the integer. The following example splits a hexadecimal number into binary nibbles as tuples:

import itertools as it
tuple(it.zip_longest(*[digitize(0x123456789ABCDEF, 2)]*4, fillvalue=0)) == ((1, 1, 1, 1), (0, 1, 1, 1), (1, 0, 1, 1), (0, 0, 1, 1), (1, 1, 0, 1), (0, 1, 0, 1), (1, 0, 0, 1), (0, 0, 0, 1), (1, 1, 1, 0), (0, 1, 1, 0), (1, 0, 1, 0), (0, 0, 1, 0), (1, 1, 0, 0), (0, 1, 0, 0), (1, 0, 0, 0))

Note that this method doesn't handle decimals, but could be adapted to.

The RestTemplate getForObject() method does not support setting headers. The solution is to use the exchange() method.

So instead of restTemplate.getForObject(url, String.class, param) (which has no headers), use

HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...

HttpEntity entity = new HttpEntity(headers);

ResponseEntity<String> response = restTemplate.exchange(
    url, HttpMethod.GET, entity, String.class, param);

Finally, use response.getBody() to get your result.

This question is similar to this question.

Here's a different example that can't be rewritten without aliases ( can't GROUP BY DISTINCT).

Imagine a table called purchases that records purchases made by customers at stores, i.e. it's a many to many table and the software needs to know which customers have made purchases at more than one store:

SELECT DISTINCT customer_id, SUM(1)
  FROM ( SELECT DISTINCT customer_id, store_id FROM purchases)
  GROUP BY customer_id HAVING 1 < SUM(1);

..will break with the error Every derived table must have its own alias. To fix:

SELECT DISTINCT customer_id, SUM(1)
  FROM ( SELECT DISTINCT customer_id, store_id FROM purchases) AS custom
  GROUP BY customer_id HAVING 1 < SUM(1);

( Note the AS custom alias).

Can you believe that the treeview on the image below does not use any JavaScript, but relies only on CSS3? Check out this CSS3 TreeView, which is good with Twitter BootStrap:

If you are using phonegap(cross-platform) and got same issue above, just remove the android platform using below command.

phonegap platform remove android

And add it again.

phonegap platform add android

Then problem solved for me.

It's not that different in bash.

workdone=0
while : ; do
  ...
  if [ "$workdone" -ne 0 ]; then
      break
  fi
done

: is the no-op command; its exit status is always 0, so the loop runs until workdone is given a non-zero value.

There are many ways you could set and test the value of workdone in order to exit the loop; the one I show above should work in any POSIX-compatible shell.

I was using old version 1.0.beta.6 of handlebars, i think somewhere during 1.1 - 1.3 this functionality was added, so updating to 1.3.0 solved the issue, here is the usage:

Usage:

{{#each object}}
  Key {{@key}} : Value {{this}}
{{/people}}

With python or pandas when you use read_csv or pd.read_csv, both of them look into current working directory, by default where the python process have started. So you need to use os module to chdir() and take it from there.

import pandas as pd 
import os
print(os.getcwd())
os.chdir("D:/01Coding/Python/data_sets/myowndata")
print(os.getcwd())
df = pd.read_csv('data.csv',nrows=10)
print(df.head())

You could use the rename(1) command:

rename 's/(.*)$/new.$1/' original.filename

Edit: If rename isn't available and you have to rename more than one file, shell scripting can really be short and simple for this. For example, to rename all *.jpg to prefix_*.jpg in the current directory:

for filename in *.jpg; do mv "$filename" "prefix_$filename"; done;

Split using a regular expression. Note I made the case more general with leading spaces. The list comprehension is to remove the null strings at the front and back.

>>> import re
>>> string = "  blah, lots  ,  of ,  spaces, here "
>>> pattern = re.compile("^\s+|\s*,\s*|\s+$")
>>> print([x for x in pattern.split(string) if x])
['blah', 'lots', 'of', 'spaces', 'here']

This works even if ^\s+ doesn't match:

>>> string = "foo,   bar  "
>>> print([x for x in pattern.split(string) if x])
['foo', 'bar']
>>>

Here's why you need ^\s+:

>>> pattern = re.compile("\s*,\s*|\s+$")
>>> print([x for x in pattern.split(string) if x])
['  blah', 'lots', 'of', 'spaces', 'here']

See the leading spaces in blah?

Clarification: above uses the Python 3 interpreter, but results are the same in Python 2.

For Excel 2013:

1. Open Blank Workbook.
2. Go to DATA tab.
3. Click button From Text in the General External Data section.
4. Select your CSV file.
5. Follow the Text Import Wizard. (in step 2, select the delimiter of your text)

In VB.NET, you need to use the GetType method to retrieve the type of an instance of an object, and the GetType() operator to retrieve the type of another known type.

Once you have the two types, you can simply compare them using the Is operator.

So your code should actually be written like this:

Sub FillCategories(ByVal Obj As Object)
    Dim cmd As New SqlCommand("sp_Resources_Categories", Conn)
    cmd.CommandType = CommandType.StoredProcedure
    Obj.DataSource = cmd.ExecuteReader
    If Obj.GetType() Is GetType(System.Web.UI.WebControls.DropDownList) Then

    End If
    Obj.DataBind()
End Sub

You can also use the TypeOf operator instead of the GetType method. Note that this tests if your object is compatible with the given type, not that it is the same type. That would look like this:

If TypeOf Obj Is System.Web.UI.WebControls.DropDownList Then

End If

Totally trivial, irrelevant nitpick: Traditionally, the names of parameters are camelCased (which means they always start with a lower-case letter) when writing .NET code (either VB.NET or C#). This makes them easy to distinguish at a glance from classes, types, methods, etc.

Looks file you use the .mkdirs() method on a File object: http://www.roseindia.net/java/beginners/java-create-directory.shtml

// Create a directory; all non-existent ancestor directories are
// automatically created
success = (new File("../potentially/long/pathname/without/all/dirs")).mkdirs();
if (!success) {
    // Directory creation failed
}

The mysql.h file from the libmysqlclient-dev Ubuntu package is located at /usr/include/mysql/mysql.h.

This is not a standard search path for compilers, however /usr/include is.

You'd typically use the mysql.h header in your code like this:

#include <mysql/mysql.h>

If you don't want to specify the directory offset in your source, you can pass the -I flag to gcc (If that's what you are using) to specify an additional include search directory, and then you wouldn't need to change your existing code.

eg.

gcc -I/usr/include/mysql ...

You can use below command to fetch verbose logs for your application package

adb logcat com.example.myapp:V *:S

Also if you have rolled out your app and you want to fetch error logs from released app, you can use below command.

adb logcat AndroidRuntime:E *:S

If you want to have the ListView in an AppCompatActivity instead of ListActivity, you can do the following (Modifying @Shardul's answer):

public class ListViewDemoActivity extends AppCompatActivity {
    //LIST OF ARRAY STRINGS WHICH WILL SERVE AS LIST ITEMS
    ArrayList<String> listItems=new ArrayList<String>();

    //DEFINING A STRING ADAPTER WHICH WILL HANDLE THE DATA OF THE LISTVIEW
    ArrayAdapter<String> adapter;

    //RECORDING HOW MANY TIMES THE BUTTON HAS BEEN CLICKED
    int clickCounter=0;
    private ListView mListView;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.activity_list_view_demo);

        if (mListView == null) {
            mListView = (ListView) findViewById(R.id.listDemo);
        }

        adapter=new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1,
                listItems);
        setListAdapter(adapter);
    }

    //METHOD WHICH WILL HANDLE DYNAMIC INSERTION
    public void addItems(View v) {
        listItems.add("Clicked : "+clickCounter++);
        adapter.notifyDataSetChanged();
    }

    protected ListView getListView() {
        if (mListView == null) {
            mListView = (ListView) findViewById(R.id.listDemo);
        }
        return mListView;
    }

    protected void setListAdapter(ListAdapter adapter) {
        getListView().setAdapter(adapter);
    }

    protected ListAdapter getListAdapter() {
        ListAdapter adapter = getListView().getAdapter();
        if (adapter instanceof HeaderViewListAdapter) {
            return ((HeaderViewListAdapter)adapter).getWrappedAdapter();
        } else {
            return adapter;
        }
    }
}

And in you layout instead of using android:id="@android:id/list" you can use android:id="@+id/listDemo"

So now you can have a ListView inside a normal AppCompatActivity.

You can do this concisely using .filter. The following example will hide all .testimonial divs containing the word "something":

$(".testimonial").filter(function() {
    return $(this).text().toLowerCase().indexOf("something") !== -1;
}).hide();

First up, this has got nothing to do with String, it is about arrays.. and that too specifically about declarative initialization of arrays.

As discussed by everyone in almost every answer here, you can, while declaring a variable, use:

String names[] = {"x","y","z"};

However, post declaration, if you want to assign an instance of an Array:

names = new String[] {"a","b","c"};

AFAIK, the declaration syntax is just a syntactic sugar and it is not applicable anymore when assigning values to variables because when values are assigned you need to create an instance properly.

However, if you ask us why it is so? Well... good luck getting an answer to that. Unless someone from the Java committee answers that or there is explicit documentation citing the said syntactic sugar.

$('tbody').find('tr:visible').hightlight(myArray[i]);

The solution is this:

  <input (click)="focusOut()" type="text" matInput [formControl]="inputControl"
  [matAutocomplete]="auto">
   <mat-autocomplete #auto="matAutocomplete" [displayWith]="displayFn" >
     <mat-option (onSelectionChange)="submitValue($event)" *ngFor="let option of 
      options | async" [value]="option">
      {{option.name | translate}}
     </mat-option>
  </mat-autocomplete>

TS
focusOut() {
this.inputControl.disable();
this.inputControl.enable();
}

Adding .gem to vendor/cache seems to work. No options required in Gemfile.

Build a new list with a list comprehension:

new_items = [x if x % 2 else None for x in items]

You can modify the original list in-place if you want, but it doesn't actually save time:

items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
for index, item in enumerate(items):
    if not (item % 2):
        items[index] = None

Here are (Python 3.6.3) timings demonstrating the non-timesave:

In [1]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: for index, item in enumerate(items):
   ...:     if not (item % 2):
   ...:         items[index] = None
   ...:
1.06 µs ± 33.7 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

In [2]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: new_items = [x if x % 2 else None for x in items]
   ...:
891 ns ± 13.6 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

And Python 2.7.6 timings:

In [1]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: for index, item in enumerate(items):
   ...:     if not (item % 2):
   ...:         items[index] = None
   ...: 
1000000 loops, best of 3: 1.27 µs per loop
In [2]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: new_items = [x if x % 2 else None for x in items]
   ...: 
1000000 loops, best of 3: 1.14 µs per loop

display: inline-block; won't work in any of IE browsers. Here is what I used.

// change the width of #boxContainer to 
// 1-2 pixels higher than total width of the boxes inside:

#boxContainer {         
    width: 800px; 
    height: auto;
    text-align: center;
    margin-left: auto;
    margin-right: auto;
}

#Box{
    width: 240px; 
    height: 90px;
    background-color: #FFF;
    float: left;
    margin-left: 10px;
    margin-right: 10px;
}

Although the other answers posted here work, I find the following approach more natural:

$obj = (object) [
    'aString' => 'some string',
    'anArray' => [ 1, 2, 3 ]
];

echo json_encode($obj);

Executing Linq queries can generate extra threads. When I try to execute code that uses Linq query collection in the immediate window it often refuses to run because not enough threads are available to the debugger.

As others have said, for threads to exit when they are finished is perfectly normal.

It is standard matplotlib.pyplot:

...
import matplotlib.pyplot as plt
plt.ylim(10, 40)

Or simpler, as mwaskom comments below:

ax.set(ylim=(10, 40))

$url = "https://chart.googleapis....";
$json = file_get_contents($url);

Now you can either echo the $json variable, if you just want to display the output, or you can decode it, and do something with it, like so:

$data = json_decode($json);
var_dump($data);

I modified the solution provided in https://stackoverflow.com/a/264088/2712152 to make it a bit more general. Also since it doesn't use any of the new C++11 features we can use it with old compilers and should also work with msvc. But the compilers should enable C99 to use this since it uses variadic macros.

The following macro can be used to check if a particular class has a particular typedef or not.

/** 
 * @class      : HAS_TYPEDEF
 * @brief      : This macro will be used to check if a class has a particular
 * typedef or not.
 * @param typedef_name : Name of Typedef
 * @param name  : Name of struct which is going to be run the test for
 * the given particular typedef specified in typedef_name
 */
#define HAS_TYPEDEF(typedef_name, name)                           \
   template <typename T>                                          \
   struct name {                                                  \
      typedef char yes[1];                                        \
      typedef char no[2];                                         \
      template <typename U>                                       \
      struct type_check;                                          \
      template <typename _1>                                      \
      static yes& chk(type_check<typename _1::typedef_name>*);    \
      template <typename>                                         \
      static no& chk(...);                                        \
      static bool const value = sizeof(chk<T>(0)) == sizeof(yes); \
   }

The following macro can be used to check if a particular class has a particular member function or not with any given number of arguments.

/** 
 * @class      : HAS_MEM_FUNC
 * @brief      : This macro will be used to check if a class has a particular

 * @param return_type: Return type of the member function
 * @param ellipsis(...) : Since this is macro should provide test case for every
 * possible member function we use variadic macros to cover all possibilities
 */
#define HAS_MEM_FUNC(func, name, return_type, ...)                \
   template <typename T>                                          \
   struct name {                                                  \
      typedef return_type (T::*Sign)(__VA_ARGS__);                \
      typedef char yes[1];                                        \
      typedef char no[2];                                         \
      template <typename U, U>                                    \
      struct type_check;                                          \
      template <typename _1>                                      \
      static yes& chk(type_check<Sign, &_1::func>*);              \
      template <typename>                                         \
      static no& chk(...);                                        \
      static bool const value = sizeof(chk<T>(0)) == sizeof(yes); \
   }

We can use the above 2 macros to perform the checks for has_typedef and has_mem_func as:

class A {
public:
  typedef int check;
  void check_function() {}
};

class B {
public:
  void hello(int a, double b) {}
  void hello() {}
};

HAS_MEM_FUNC(check_function, has_check_function, void, void);
HAS_MEM_FUNC(hello, hello_check, void, int, double);
HAS_MEM_FUNC(hello, hello_void_check, void, void);
HAS_TYPEDEF(check, has_typedef_check);

int main() {
  std::cout << "Check Function A:" << has_check_function<A>::value << std::endl;
  std::cout << "Check Function B:" << has_check_function<B>::value << std::endl;
  std::cout << "Hello Function A:" << hello_check<A>::value << std::endl;
  std::cout << "Hello Function B:" << hello_check<B>::value << std::endl;
  std::cout << "Hello void Function A:" << hello_void_check<A>::value << std::endl;
  std::cout << "Hello void Function B:" << hello_void_check<B>::value << std::endl;
  std::cout << "Check Typedef A:" << has_typedef_check<A>::value << std::endl;
  std::cout << "Check Typedef B:" << has_typedef_check<B>::value << std::endl;
}

Without Error Handeling

//Load background texture
 new THREE.TextureLoader();
loader.load('https://images.pexels.com/photos/1205301/pexels-photo-1205301.jpeg' , function(texture)
            {
             scene.background = texture;  
            });

With Error Handling

// Function called when download progresses
var onProgress = function (xhr) {
  console.log((xhr.loaded / xhr.total * 100) + '% loaded');
};

// Function called when download errors
var onError = function (error) {
  console.log('An error happened'+error);
};

//Function  called when load completes.
var onLoad = function (texture) {
  var objGeometry = new THREE.BoxGeometry(30, 30, 30);
  var objMaterial = new THREE.MeshPhongMaterial({

A lot of answers above have fields compared in single comparator method which is not actually working. There are some answers though with different comparators implemented for each field, I am posting this because this example would be much more clearer and simple to understand I am believing.

class Student{
    Integer bornYear;
    Integer bornMonth;
    Integer bornDay;
    public Student(int bornYear, int bornMonth, int bornDay) {

        this.bornYear = bornYear;
        this.bornMonth = bornMonth;
        this.bornDay = bornDay;
    }
    public Student(int bornYear, int bornMonth) {

        this.bornYear = bornYear;
        this.bornMonth = bornMonth;

    }
    public Student(int bornYear) {

        this.bornYear = bornYear;

    }
    public Integer getBornYear() {
        return bornYear;
    }
    public void setBornYear(int bornYear) {
        this.bornYear = bornYear;

This is a modification of @mousio's answer. My network connection is not persistent hence the IP address of the next adapter gets displayed if the string "IPv4 Address" is missing from ipconfig. The result of ipconfig has 2 blank spaces between adapters. After an adapter is found and 2 blank lines occurs before the "IPv4 Address" text, it assumes it is missing. Tested on Windows 7 64-bit only.

Processing blank lines from @dbenham's answer in: DOS batch FOR loop with FIND.exe is stripping out blank lines?

ProtocolBuffers is FASTER.
There is a nice benchmark here:
http://code.google.com/p/thrift-protobuf-compare/wiki/Benchmarking

You might also want to look into Avro, as Avro is even faster.
Microsoft has a package here:
http://www.nuget.org/packages/Microsoft.Hadoop.Avro

By the way, the fastest I've ever seen is Cap'nProto;
A C# implementation can be found at the Github-repository of Marc Gravell.

I had this issue recently,

Problem statement: Mine was a windows service that I run locally by attaching VS debugger. When I stop debugging and try to restart/stop the service (under services.msc) I used to get the mentioned error.

Solution:

1. Open up Task manager.
2. Search for the service (based on the exe name and not service name, for those that are different).
3. Kill the service.

On doing the above the service is stopped.

Do you mean compile it to JAR? NetBeans does that automatically, just do "clean and build" and look in the "dist" subdirectory of your project. There will be the JAR with "lib" folder containing the required libraries. These JAR + lib are enough to run the application.

If you disable "Compile on save" in the project properties, then it is no longer necessary to do "clean and build", simply "build" will suffice in most cases. This will save time if you want to change just a bit of the code and rebuild the JAR. However, note that NetBeans sometimes fails to handle dependencies and binary compatibility properly, which will lead to a faulty JAR throwing "no such method" or other obscure exceptions. Therefore, if you made a lot of changes since the last full rebuild and even remotely unsure that it will still work even if some classes aren't recompiled, then you must still do a full "clean and build" in order to get a perfectly working JAR.

Totally based on @Whymarrh's answer, this is my implementation, tested and working fine, no dependencies:

public static String getSha1Hex(String clearString)
{
    try
    {
        MessageDigest messageDigest = MessageDigest.getInstance("SHA-1");
        messageDigest.update(clearString.getBytes("UTF-8"));
        byte[] bytes = messageDigest.digest();
        StringBuilder buffer = new StringBuilder();
        for (byte b : bytes)
        {
            buffer.append(Integer.toString((b & 0xff) + 0x100, 16).substring(1));
        }
        return buffer.toString();
    }
    catch (Exception ignored)
    {
        ignored.printStackTrace();
        return null;
    }
}

@Ethan's answer would completely work. From my experience, the more node way is to use environment variables. It's a standard way to configure programs deployed on hosting platforms (e.g. Heroku or Dokku).

To pass the parameter from the command line, do it like this:

Development: gulp dev

Production: NODE_ENV=production gulp dev

The syntax is different, but very Unix, and it's compatible with Heroku, Dokku, etc.

You can access the variable in your code at process.env.NODE_ENV

MYAPP=something_else gulp dev

would set

process.env.MYAPP === 'something_else'

This answer might give you some other ideas.

For the past two days I've been experimenting with Dotfuscator Community Edition advanced (a free download after registering the basic CE that comes bundled with Visual Studio).

I think the reason more people don't use obfuscation as a default option is that it's a serious hassle compared to the risk. On smaller test projects I could get the obfuscated code running with a lot of effort. Deploying a simple project via ClickOnce was troublesome, but achievable after manually signing the manifests with mage. The only problem was that on error the stack trace came back obfuscated and the CE doesn't have a deobfuscator or clarifier packaged.

I tried to obfuscate a real project which is VSTO based in Excel, with Virtual Earth integration, lots of webservice calls and an IOC container and lot's of reflection. It was impossible.

If obfuscation is really a critical requirement, you should design your application with that in mind from the start, testing the obfuscated builds as you progress. Otherwise, if it's a fairly complex project, you're going to end up with a serious amount of pain.

The UUID stands for Universally Unique Identifier. UUID is an simple 128 bit digit which uniquely distributed across the world.

Bluetooth sends data over air and all nearby device can receive it. Let's suppose, sometimes you have to send some important files via Bluetooth and all near by devices can access it in range. So when you pair with the other devices, they simply share the UUID number and match before sharing the files. When you send any file then your device encrypt that file with appropriate device UUID and share over the network. Now all Bluetooth devices in the range can access the encrypt file but they required right UUID number. So Only right UUID devices have access to encrypt the file and others will reject cause of wrong UUID.

In short, you can use UUID as a secret password for sharing files between any two Bluetooth devices.

Here is the method by using explode:

$text = explode('_', '233718_This_is_a_string', 2)[1]; // Returns This_is_a_string

or:

$text = @end((explode('_', '233718_This_is_a_string', 2)));

By specifying 2 for the limit parameter in explode(), it returns array with 2 maximum elements separated by the string delimiter. Returning 2nd element ([1]), will give the rest of string.

Here is another one-liner by using strpos (as suggested by @flu):

$needle = '233718_This_is_a_string';
$text = substr($needle, (strpos($needle, '_') ?: -1) + 1); // Returns This_is_a_string

git read-tree -um @ $commit_to_revert_to

will do it. It's "git checkout" but without updating HEAD.

You can achieve the same effect with

git checkout $commit_to_revert_to
git reset --soft @{1}

if you prefer stringing convenience commands together.

These leave you with your worktree and index in the desired state, you can just git commit to finish.

Bit less elegant but can also do:

sl[len(sl)-1: len(sl)]

I needed to update my php from 5.3.8 to 5.3.29. (both Thread Safe) on Windows

Steps I did:

1. Back-up my initial php folder, under xampp.
2. Downloaded zip from here http://windows.php.net/download/#php-5.3-ts-VC9-x86
3. Unpack that zip into xampp folder.
4. Copied php.ini file from old php folder into new one.
5. Copied a couple of folders that I didn't have in the new php folder, from old one. For example: extras, which contained browscap.ini file (this one is needed)
6. Copied needed extensions, from old php ext folder into new php ext folder. I copied them manually, by checking list of extensions from php.ini file.
7. Copied also these files: php5apache2_2.dll, php5ts.dll

Hope that I covered everything.

Most probably these steps will not work if you change major versions of php, e.g. 5.3.x to 5.4.x, but for minor versions, it should work.

Also, a good way to see what's wrong... start command line and try to start httpd.exe, under xampp/apache/bin from there, it will list errors found.

In Europe we have this problem must earlier than this question. In Europe we use all a comma for a decimal point. See this numbers below:

| American      | Europe        |
| ------------- | ------------- |
| 0.5           | 0,5           |
| 3.14159265359 | 3,14159265359 |
| 17.54         | 17,54         |
| 175,186.15    | 175.186,15    |

So it isn't possible to use the comma separator for CSV files. Because of that reason, the CSV files in Europe are separated by a semicolon (;).

Programs like Microsoft Excel can read files with a semicolon and it's possible to switch from separator. You could even use a tab (\t) as separator. See this answer from Supper User.

Method 1:

If the method DoSomethingBeta was static you need only call:

Beta.DoSomethingBeta();

Method 2:

If Alpha extends from Beta you could call DoSomethingBeta() directly.

public class Alpha extends Beta{
     public void DoSomethingAlpha() {
          DoSomethingBeta();  //?
     }
}

Method 3:

Alternatively you need to have access to an instance of Beta to call the methods from it.

public class Alpha {
     public void DoSomethingAlpha() {
          Beta cbeta = new Beta();
          cbeta.DoSomethingBeta();  //?
     }
}

Incidentally is this homework?

I am happy with the listings package:

Here is how I configure it:

\lstset{
language=C,
basicstyle=\small\sffamily,
numbers=left,
numberstyle=\tiny,
frame=tb,
columns=fullflexible,
showstringspaces=false
}

I use it like this:

\begin{lstlisting}[caption=Caption example.,
  label=a_label,
  float=t]
// Insert the code here
\end{lstlisting}

MYSQL 8 does, in a way:

MYSQL 8 supports JSON tables, so you could load your results into a JSON variable and select from that variable using the JSON_TABLE() command.

Go to conversation tab then come down there is one "close pull request" button is there use that button to close pull request, Take ref of attached image

Check This:

DECLARE
    @_month TINYINT         = 5,
    @_year SMALLINT         = 2020,
    @date_ref DATETIME      = NULL 


    IF @_year IS NULL
        SET @date_ref = GETDATE() - 430
    ELSE
    BEGIN
        SELECT @date_ref = CAST ( CAST ( @_year AS VARCHAR (4)) 
            + 
            CASE 
                WHEN @_month < 10 THEN '0' + CAST ( @_month AS VARCHAR(1)) 
                ELSE CAST ( @_month AS VARCHAR(2)) 
            END 
            + 
            '01' AS DATETIME )
    END

Don't know if this is too late but you can use np.where to find the indices of non values as such:

indices = list(np.where(df['b'].isna()[0]))

I see that all of the answers suggest using a list filled with Object classes and then explicitly casting the desired class, and I personally don't like that kind of approach.

What works better for me is to create an interface which contains methods for retrieving or storing data from/to certain classes I want to put in a list. Have those classes implement that new interface, add the methods from the interface into them and then you can fill the list with interface objects - List<NewInterface> newInterfaceList = new ArrayList<>() thus being able to extract the desired data from the objects in a list without having the need to explicitly cast anything.

You can also put a comparator in the interface if you need to sort the list.

This is an implementation of aforementioned StanLe's anwer, also fixing the case where his answer would produce no curve when using densities.

This replaces the existing but hidden hist.default() function, to only add the normalcurve parameter (which defaults to TRUE).

Your idea with the SequenceGenerator fake entity is good.

@Id
@GenericGenerator(name = "my_seq", strategy = "sequence", parameters = {
        @org.hibernate.annotations.Parameter(name = "sequence_name", value = "MY_CUSTOM_NAMED_SQN"),
})
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "my_seq")

It is important to use the parameter with the key name "sequence_name". Run a debugging session on the hibernate class SequenceStyleGenerator, the configure(...) method at the line final QualifiedName sequenceName = determineSequenceName( params, dialect, jdbcEnvironment ); to see more details about how the sequence name is computed by Hibernate. There are some defaults in there you could also use.

After the fake entity, I created a CrudRepository:

public interface SequenceRepository extends CrudRepository<SequenceGenerator, Long> {}

In the Junit, I call the save method of the SequenceRepository.

SequenceGenerator sequenceObject = new SequenceGenerator(); SequenceGenerator result = sequenceRepository.save(sequenceObject);

If there is a better way to do this (maybe support for a generator on any type of field instead of just Id), I would be more than happy to use it instead of this "trick".

In :nums = [1, 2, 3]

In :map(add, nums, [2]*len(nums))

Out:[3, 4, 5]

I had trouble using the above, and I needed the IP address from a controller. I used the following in the end:

System.Web.HttpContext.Current.Request.UserHostAddress

In psql that would be

\dx

See the manual for details: http://www.postgresql.org/docs/current/static/app-psql.html

Doing it in plain SQL it would be a select on pg_extension:

SELECT * 
FROM pg_extension

You can add and retrieve a numpy array from dataframe using this:

import numpy as np
import pandas as pd

df = pd.DataFrame({'b':range(10)}) # target dataframe
a = np.random.normal(size=(10,2)) # numpy array
df['a']=a.tolist() # save array
np.array(df['a'].tolist()) # retrieve array

This builds on the previous answer that confused me because of the sparse part and this works well for a non-sparse numpy arrray.

Check your compileSdkVersion on app build.gradle. Set it to 21:

This will write the time & date every 20 seconds in the file ping_ip.txt. The second to last line just says run the same batch file again, and agan, and again,..........etc.

Does not seem to create multiple instances, so that's a good thing.

@echo %time% %date% >>ping_ip.txt
ping -n 20 -w 3 127.0.0.1 >>ping_ip.txt

Just open a bug report with your OS vendor asking them to put the socket in /var/run so it automagically gets removed at reboot. It's a bug to keep this socket after an unclean reboot, /var/run is the spot for these kinds of files.

You can use the :before and :after pseudo-classes to put a multi-layered background on a element.

#divID : before {
    background: url(someImage);
}

#div : after {
    background : url(someotherImage) -10% no-repeat;
}

An actual JSON request would look like this:

data: '{"command":"on"}',

Where you're sending an actual JSON string. For a more general solution, use JSON.stringify() to serialize an object to JSON, like this:

data: JSON.stringify({ "command": "on" }),

To support older browsers that don't have the JSON object, use json2.js which will add it in.

What's currently happening is since you have processData: false, it's basically sending this: ({"command":"on"}).toString() which is [object Object]...what you see in your request.

import json
data = json.load(open('/Users/laxmanjeergal/Desktop/json.json'))
jtopy=json.dumps(data) #json.dumps take a dictionary as input and returns a string as output.
dict_json=json.loads(jtopy) # json.loads take a string as input and returns a dictionary as output.
print(dict_json["shipments"])

I prefer null, since it's compatible with the null-coalescing operator (??).

"How to find all a which are children of <li class=test> but not any others?"

Given the HTML below (I added another <a> to show te difference between select and select_one):

<div>
  <li class="test">
    <a>link1</a>
    <ul>
      <li>
        <a>link2</a>
      </li>
    </ul>
    <a>link3</a>
  </li>
</div>

The solution is to use child combinator (>) that is placed between two CSS selectors:

>>> soup.select('li.test > a')
[<a>link1</a>, <a>link3</a>]

In case you want to find only the first child:

>>> soup.select_one('li.test > a')
<a>link1</a>

I've found nosklo's answer very extensive and useful! For those, like myself, who might find accessing the raw request data directly also useful, I would like to add the way to do that:

import os, sys

# the query string, which contains the raw GET data
# (For example, for http://example.com/myscript.py?a=b&c=d&e
# this is "a=b&c=d&e")
os.getenv("QUERY_STRING")

# the raw POST data
sys.stdin.read()

You can add a function to String Object

//Add this wherever you like in your javascript code
String.prototype.isEmail = function() {
    return !!this.match(/^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$/);
}

var user_email = "[email protected]";

if(user_email.isEmail()) {
    //Email is valid !
} else {
    //Email is invalid !
}

Regarding Phil Street's post:

It may actually be installed in your 32-bit program folder instead of your default x64, if you're running 64-bit OS. Check to see where 7-zip is installed, and if it is in Program Files (x86) then try using this instead:

PATH=%PATH%;C:\Program Files (x86)\7-Zip

since the data ex1221new was not given, so I have created a dummy data and added it to a data frame. Also, the question which was asked has few changes in codes like then ggplot package has deprecated the use of

"scale_area()" and nows uses scale_size_area()
"opts()" has changed to theme()

In my answer,I have stored the plot in mygraph variable and then I have used

mygraph$labels$x="Discharge of materials" #changes x axis title
       mygraph$labels$y="Area Affected" # changes y axis title

And the work is done. Below is the complete answer.

install.packages("Sleuth2")
library(Sleuth2)
library(ggplot2)

ex1221new<-data.frame(Discharge<-c(100:109),Area<-c(120:129),NO3<-seq(2,5,length.out = 10))
discharge<-ex1221new$Discharge
area<-ex1221new$Area
nitrogen<-ex1221new$NO3
p <- ggplot(ex1221new, aes(discharge, area), main="Point")
mygraph<-p + geom_point(aes(size= nitrogen)) + 
  scale_size_area() + ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")+
theme(
 plot.title =  element_text(color="Blue", size=30, hjust = 0.5), 

 # change the styling of both the axis simultaneously from this-
 axis.title = element_text(color = "Green", size = 20, family="Courier",)
 

   # you can change the  axis title from the code below
   mygraph$labels$x="Discharge of materials" #changes x axis title
   mygraph$labels$y="Area Affected" # changes y axis title
   mygraph



   

Also, you can change the labels title from the same formula used above -

mygraph$labels$size= "N2" #size contains the nitrogen level 

Use set -e

#!/bin/bash

set -e

/bin/command-that-fails
/bin/command-that-fails2

The script will terminate after the first line that fails (returns nonzero exit code). In this case, command-that-fails2 will not run.

If you were to check the return status of every single command, your script would look like this:

#!/bin/bash

# I'm assuming you're using make

cd /project-dir
make
if [[ $? -ne 0 ]] ; then
    exit 1
fi

cd /project-dir2
make
if [[ $? -ne 0 ]] ; then
    exit 1
fi

With set -e it would look like:

#!/bin/bash

set -e

cd /project-dir
make

cd /project-dir2
make

Any command that fails will cause the entire script to fail and return an exit status you can check with $?. If your script is very long or you're building a lot of stuff it's going to get pretty ugly if you add return status checks everywhere.

Interesting question - I don't think there's any Oracle function that does this (almost like a "which" command in Unix), but you can get the resolution order for the name by:

select * from 
(
 select  object_name objname, object_type, 'my object' details, 1 resolveOrder 
  from user_objects
  where object_type not like 'SYNONYM'
 union all
 select synonym_name obj , 'my synonym', table_owner||'.'||table_name, 2 resolveOrder
  from user_synonyms
 union all
 select  synonym_name obj , 'public synonym', table_owner||'.'||table_name, 3 resolveOrder
  from all_synonyms where owner = 'PUBLIC'
)
where objname like upper('&objOfInterest')

In the case of HashMap, it replaces the old value with the new one.

In the case of HashSet, the item isn't inserted.

I am using phpMyAdmin Server version: 5.1.41.

It offers possibility for view sql history through phpmyadmin.pma_history table.

You can search your query in this table.

pma_history table has below structure:

This is a general solution to loading data into a C++ program, and uses the readline function. This could be modified for CSV files, but the delimiter is a space here.

int n = 5, p = 2;

int X[n][p];

ifstream myfile;

myfile.open("data.txt");

string line;
string temp = "";
int a = 0; // row index 

while (getline(myfile, line)) { //while there is a line
     int b = 0; // column index
     for (int i = 0; i < line.size(); i++) { // for each character in rowstring
          if (!isblank(line[i])) { // if it is not blank, do this
              string d(1, line[i]); // convert character to string
              temp.append(d); // append the two strings
        } else {
              X[a][b] = stod(temp);  // convert string to double
              temp = ""; // reset the capture
              b++; // increment b cause we have a new number
        }
    }

  X[a][b] = stod(temp);
  temp = "";
  a++; // onto next row
}

I think its better to to do text-align center for div and let image take care of the height. Just specify a top and bottom padding for div to have space between image and div. Look at this example: http://jsfiddle.net/Tv9mG/

You could fairly easily run this through the CSharpCodeProvider with suitable fluff wrapping it (a type and a method, basically). Likewise you could go through VB etc - or JavaScript, as another answer has suggested. I don't know of anything else built into the framework at this point.

I'd expect that .NET 4.0 with its support for dynamic languages may well have better capabilities on this front.

AddType application/x-httpd-php54 .php

First off, avoid using the default package.

Second of all, you don't need to import the class; it's in the same package.

For Fedora (can be useful for someone)

sudo dnf install zlib-1.2.8-10.fc24.i686 libgcc-6.1.1-2.fc24.i686

I just had this and as has happened to me in the past it didn't work because I didn't pay attention to the autocomplete when trying to add the method and I actually end up implementing tableView:didDeselectRowAtIndexPath: instead of tableView:didSelectRowAtIndexPath:.

Adding to what @KyleMit said, consider using:

• col-md-* classes for the larger outer columns
• col-xs-* classes for the smaller inner columns

This will be useful when you view the page on different screen sizes.

On a small screen, the wrapping of larger outer columns will then happen while maintaining the smaller inner columns, if possible

EDIT: @mblase75 added more concise code to the earlier answer while I was writing mine, so I recommend going with his solution.

You could use code like this:

var longArray = ["Element 1","Element 2","Element 3", /*...*/];
var smallerArrays = []; // will contain the sub-arrays of 10 elements each
var arraySize = 10;
for (var i=0;i<Math.ceil(longArray.length/arraySize);i++) {
    smallerArrays.push(longArray.slice(i*arraySize,i*arraySize+arraySize));
}

Change the value of arraySize to change the maximum length of the smaller arrays.

deleted the c#... here is the vb.net

<%=Html.ActionLink("Home", "Index", "Home", New With {.class = "tab"}, Nothing)%>

full path for binary file. For example: /home/vitaliy2034/binary_file_name. Or use directive "./+binary_file_name". './' in unix system it return full path to directory, in which you open terminal(shell). I hope it helps. Sorry, for my english language)

Ok, I just found a VERY ugly solution :

public static Animation expand(final View v, Runnable onEnd) {
    try {
        Method m = v.getClass().getDeclaredMethod("onMeasure", int.class, int.class);
        m.setAccessible(true);
        m.invoke(
            v,
            MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
            MeasureSpec.makeMeasureSpec(((View)v.getParent()).getMeasuredHeight(), MeasureSpec.AT_MOST)
        );
    } catch (Exception e){
        Log.e("test", "", e);
    }
    final int initialHeight = v.getMeasuredHeight();
    Log.d("test", "initialHeight="+initialHeight);

    v.getLayoutParams().height = 0;
    v.setVisibility(View.VISIBLE);
    Animation a = new Animation()
    {
        @Override
        protected void applyTransformation(float interpolatedTime, Transformation t) {
            final int newHeight = (int)(initialHeight * interpolatedTime);
            v.getLayoutParams().height = newHeight;
            v.requestLayout();
        }

        @Override
        public boolean willChangeBounds() {
            return true;
        }
    };
    a.setDuration(5000);
    v.startAnimation(a);
    return a;
}

Feel free to propose a better solution !

found a way at http://www.dotnetspider.com/resources/21866-Count-pages-PDF-file.aspx this does not require purchase of a pdf library

func.__code__.co_argcount gives you number of any arguments BEFORE *args

func.__kwdefaults__ gives you a dict of the keyword arguments AFTER *args

func.__code__.co_kwonlyargcount is equal to len(func.__kwdefaults__)

func.__defaults__ gives you the values of optional arguments that appear before *args

Here is the simple illustration:

>>> def a(b, c, d, e, f=1, g=3, h=None, *i, j=2, k=3, **L):
    pass

>>> a.__code__.co_argcount
7
>>> a.__defaults__
(1, 3, None)
>>> len(a.__defaults__)
3
>>> 
>>> 
>>> a.__kwdefaults__
{'j': 2, 'k': 3}
>>> len(a.__kwdefaults__)
2
>>> a.__code__.co_kwonlyargcount

I suggest sty. It's similar to colorama, but less verbose and it supports 8bit and 24bit colors. You can also extend the color register with your own colors.

Examples:

from sty import fg, bg, ef, rs

foo = fg.red + 'This is red text!' + fg.rs
bar = bg.blue + 'This has a blue background!' + bg.rs
baz = ef.italic + 'This is italic text' + rs.italic
qux = fg(201) + 'This is pink text using 8bit colors' + fg.rs
qui = fg(255, 10, 10) + 'This is red text using 24bit colors.' + fg.rs

# Add custom colors:

from sty import Style, RgbFg

fg.orange = Style(RgbFg(255, 150, 50))

buf = fg.orange + 'Yay, Im orange.' + fg.rs

print(foo, bar, baz, qux, qui, buf, sep='\n')

Demo:

I updated yarn on my Ubuntu by running the following command from my terminal

curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

source:https://yarnpkg.com/lang/en/docs/cli/self-update

i came across the same thing and i figured out what is the issue. When we use the method input, the response we should type should be in double quotes. Like in your line date=input("Example: March 21 | What is the date? ")

You should type when prompted on console "12/12/2015" - note the " thing before and after. This way it will take that as a string and process it as expected. I am not sure if this is limitation of this input method - but it works this way.

Hope it helps

abs() : Returns the absolute value as per the argument i.e. if argument is int then it returns int, if argument is float it returns float. Also it works on complex variable also i.e. abs(a+bj) also works and returns absolute value i.e.math.sqrt(((a)**2)+((b)**2)

math.fabs() : It only works on the integer or float values. Always returns the absolute float value no matter what is the argument type(except for the complex numbers).

            txtarea = new JTextArea(); 
    txtarea.setRows(25);
    txtarea.setColumns(25);
    txtarea.setWrapStyleWord(true);
    JScrollPane scroll = new JScrollPane (txtarea);
    panel2.add(scroll); //Object of Jpanel

Above given lines automatically shows you both horizontal & vertical Scrollbars..

I would suggest using a TableValue user function if you'd like to encapsulate the Inner Join or temp table techniques shown above. This would allow it to read a bit more clearly.

After using the split function defined at: http://www.logiclabz.com/sql-server/split-function-in-sql-server-to-break-comma-separated-strings-into-table.aspx

we can write the following based on a table I created called "Fish" (int id, varchar(50) Name)

SELECT Fish.* from Fish 
    JOIN dbo.Split('%ass,%e%',',') as Splits 
    on Name like Splits.items  //items is the name of the output column from the split function.

Outputs

1   Bass
2   Pike
7   Angler
8   Walleye

Before Java 8 (versions 7 or 6) I use the new method ArgumentMatchers.anyList:

import static org.mockito.Mockito.*;
import org.mockito.ArgumentMatchers;

verify(mock, atLeastOnce()).process(ArgumentMatchers.<Bar>anyList());

You can just create the required CORS configuration as a bean. As per the code below this will allow all requests coming from any origin. This is good for development but insecure. Spring Docs

@Bean
WebMvcConfigurer corsConfigurer() {
    return new WebMvcConfigurer() {
        @Override
        void addCorsMappings(CorsRegistry registry) {
            registry.addMapping("/**")
                    .allowedOrigins("*")
        }
    }
}

Just to show an example of how to dynamically add the "Content-type" header to every POST request. In may case I'm passing POST params as query string, that is done using the transformRequest. In this case its value is application/x-www-form-urlencoded.

// set Content-Type for POST requests
angular.module('myApp').run(basicAuth);
function basicAuth($http) {
    $http.defaults.headers.post = {'Content-Type': 'application/x-www-form-urlencoded'};
}

Then from the interceptor in the request method before return the config object

// if header['Content-type'] is a POST then add data
'request': function (config) {
  if (
    angular.isDefined(config.headers['Content-Type']) 
    && !angular.isDefined(config.data)
  ) {
    config.data = '';
  }
  return config;
}

Even your "long" list is pretty short. Also, did you choose them to match the actual data? Performance will vary with what these data actually look like. For example, you have a short list repeated over and over to make a longer list. This means that the quadratic solution is linear in your benchmarks, but not in reality.

For actually-large lists, the set code is your best bet—it's linear (although space-hungry). The sort and groupby methods are O(n log n) and the loop in method is obviously quadratic, so you know how these will scale as n gets really big. If this is the real size of the data you are analyzing, then who cares? It's tiny.

Incidentally, I'm seeing a noticeable speedup if I don't form an intermediate list to make the set, that is to say if I replace

kt = [tuple(i) for i in k]
skt = set(kt)

with

skt = set(tuple(i) for i in k)

The real solution may depend on more information: Are you sure that a list of lists is really the representation you need?

Use the below to check the table description for a single table

DESCRIBE TABLE Schema Name.Table Name

join the below tables to check the table description for a multiple tables, join with the table id syscat.tables and syscat.columns

You can also check the details of indexes on the table using the below command describe indexes for table . show detail

From the PHP Manual:

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

mysqli_connect()

PDO::__construct()

use MySQLi or PDO

<?php
$con = mysqli_connect('localhost', 'username', 'password', 'database');

I developed a plugin and installed it on a Wordpress site running on Nginx and it was fine. I only had this error when I switched to Apache, turned out the web server was not accepting the <?, so I just replaced the <? tags to <?php then it worked.

sudo nginx -t should test all files and return errors and warnings locations

Use the in_array() function.

$array = array('kitchen', 'bedroom', 'living_room', 'dining_room');

if (in_array('kitchen', $array)) {
    echo 'this array contains kitchen';
}

This is just the XML Name Space declaration. We use this Name Space in order to specify that the attributes listed below, belongs to Android. Thus they starts with "android:"

You can actually create your own custom attributes. So to prevent the name conflicts where 2 attributes are named the same thing, but behave differently, we add the prefix "android:" to signify that these are Android attributes.

Thus, this Name Space declaration must be included in the opening tag of the root view of your XML file.

I would not use KML. Instead, use GeoJSON which you can natively consume in Google Maps API now. It is a newer feature that didn't exist from the original responses.

In any case, simply open the SHP file in Quantum GIS, and then you can output it in any format you like (KML, GeoJSON).

If you are using Google Maps for Work, I found a premium extension that handles loading shapefiles directly where you can just connect direct to the shapefile that you generate from ESRI. I did a search on the CMaps site and found this snippet which loaded US by state shapefile: https://gmapsplugin.net/cmapsanalytics/assets/shapes/usstates.shp

var cMap = new centigon.locationIntelligence.MapView();
    cMap.key([your_api_key]);


    cMap.layerNames(["Basic Shapes"]);
    cMap.dbfKeys([['Alabama','Alaska','Arizona','Arkansas','California','Colorado','Connecticut','Delaware','District of Columbia','Florida','Georgia','Hawaii','Idaho','Illinois','Indiana','Iowa','Kansas','Kentucky','Louisiana','Maine','Maryland','Massachusetts','Michigan','Minnesota','Mississippi','Missouri','Montana','Nebraska','Nevada','New Hampshire','New Jersey','New Mexico','New York','North Carolina','North Dakota','Ohio','Oklahoma','Oregon','Pennsylvania','Rhode Island','South Carolina','South Dakota','Tennessee','Texas','Utah','Vermont','Virginia','Washington','West Virginia','Wisconsin','Wyoming']]);

You can do a printf to anything that is an OutputStream with a PrintStream. Somehow like this, printing into a string stream:

PrintStream ps = new PrintStream(baos);
ps.printf("there is a %s from %d %s", "hello", 3, "friends");
System.out.println(baos.toString());
baos.reset(); //need reset to write new string
ps.printf("there is a %s from %d %s", "flip", 5, "haters");
System.out.println(baos.toString());
baos.reset();

The string stream can be created like this ByteArrayOutputStream:

ByteArrayOutputStream baos = new ByteArrayOutputStream();

After messing around with @BringBackCommodore64 answer I figured it out

[link](file:///d:/absolute.md)    # absolute filesystem path
[link](./relative1.md)            # relative to opened file
[link](/relativeToProject.md)     # relative to opened project

All of them tested in Visual Studio Code and working,

Note: The absolute path works in editor but doesn't work in markdown preview mode!

There is no need to invoke PHP for this. Just put it directly into the HTML:

<a href="http://www.example.com/">...

None/Null is a data type of the class NoneType in pyspark/python so, Below will not work as you are trying to compare NoneType object with string object

df[df.dt_mvmt == None].count() 0 df[df.dt_mvmt != None].count() 0

correct

df=df.where(col("dt_mvmt").isNotNull()) returns all records with dt_mvmt as None/Null

You could have the extension set a cookie and have your websites JavaScript check if that cookie is present and update accordingly. This and probably most other methods mentioned here could of course be cirvumvented by the user, unless you try and have the extension create custom cookies depending on timestamps etc, and have your application analyze them server side to see if it really is a user with the extension or someone pretending to have it by modifying his cookies.

I ran into this same issue, but I think I know what's causing the confusion. If you use MySql Query Analyzer, you can do this just fine:

SELECT myvalue 
INTO @myvar 
FROM mytable 
WHERE anothervalue = 1;

However, if you put that same query in MySql Workbench, it will throw a syntax error. I don't know why they would be different, but they are. To work around the problem in MySql Workbench, you can rewrite the query like this:

SELECT @myvar:=myvalue
FROM mytable
WHERE anothervalue = 1;

Treating the database as just a storage mechanism (i.e. glorified collections library) and hence subordinate to their application (ignoring other applications which share the data)

Here I can't see even a single correct answer for this question (in WinForms tag) and it's strange for such frequent question.

Items of a ListBox control may be DataRowView, Complex Objects, Anonymous types, primary types and other types. Underlying value of an item should be calculated base on ValueMember.

ListBox control has a GetItemText which helps you to get the item text regardless of the type of object you added as item. It really needs such GetItemValue method.

GetItemValue Extension Method

We can create GetItemValue Extension Method to get item value which works like GetItemText:

using System;
using System.Windows.Forms;
using System.ComponentModel;
public static class ListControlExtensions
{
    public static object GetItemValue(this ListControl list, object item)
    {
        if (item == null)
            throw new ArgumentNullException("item");

        if (string.IsNullOrEmpty(list.ValueMember))
            return item;

        var property = TypeDescriptor.GetProperties(item)[list.ValueMember];
        if (property == null)
            throw new ArgumentException(
                string.Format("item doesn't contain '{0}' property or column.",
                list.ValueMember));
        return property.GetValue(item);
    }
}

Using above method you don't need to worry about settings of ListBox and it will return expected Value for an item. It works with List<T>, Array, ArrayList, DataTable, List of Anonymous Types, list of primary types and all other lists which you can use as data source. Here is an example of usage:

//Gets underlying value at index 2 based on settings
this.listBox1.GetItemValue(this.listBox1.Items[2]);

Since we created the GetItemValue method as an extension method, when you want to use the method, don't forget to include the namespace which you put the class in.

This method is applicable on ComboBox and CheckedListBox too.

It is more appropriate to approach this problem with the mentality that a form will have a default action tied to one submit button, and then an alternative action bound to a plain button. The difference here is that whichever one goes under the submit will be the one used when a user submits the form by pressing enter, while the other one will only be fired when a user explicitly clicks on the button.

Anyhow, with that in mind, this should do it:

<form id='myform' action='jquery.php' method='GET'>
    <input type='submit' id='btn1' value='Normal Submit'>
    <input type='button' id='btn2' value='New Window'>
</form>

With this javascript:

var form = document.getElementById('myform');
form.onsubmit = function() {
    form.target = '_self';
};

document.getElementById('btn2').onclick = function() {
    form.target = '_blank';
    form.submit();
}

Approaches that bind code to the submit button's click event will not work on IE.

I encountered this error with an Azure DevOps Services (MS-hosted) build pipeline on a TFVC repo.

In my case, I was working within a branch and had accidentally added the reference from the package folder in trunk instead of from the branch. Once I added the reference from within the branch, it started compiling successfully.

I.e., while working on \branch-beta\sierra.csproj, I accidentally referenced \trunk\packages\delta.dll. Obviously, I needed to reference \branch-beta\packages\delta.dll instead. The mixup occurred because the path is not prominently displayed in the Add Reference window and I didn’t check carefully enough.

Eric Niebler is working on a range-proposal and some of the examples show how to remove certain elements. Removing 8. Does create a new vector.

#include <iostream>
#include <range/v3/all.hpp>

int main(int argc, char const *argv[])
{
    std::vector<int> vi{2,4,6,8,10};
    for (auto& i : vi) {
        std::cout << i << std::endl;
    }
    std::cout << "-----" << std::endl;
    std::vector<int> vim = vi | ranges::view::remove_if([](int i){return i == 8;});
    for (auto& i : vim) {
        std::cout << i << std::endl;
    }
    return 0;
}

outputs

if you're looking for a snippet that would work for all your modals, and search automatically for the 1st input text in the opened one, you should use this:

$('.modal').on('shown.bs.modal', function () {
    $(this).find( 'input:visible:first').focus();
});

If your modal is loaded using ajax, use this instead:

$(document).on('shown.bs.modal', '.modal', function() {
    $(this).find('input:visible:first').focus();
});

I'd recommend adopting Syslog severity levels: DEBUG, INFO, NOTICE, WARNING, ERROR, CRITICAL, ALERT, EMERGENCY.
See http://en.wikipedia.org/wiki/Syslog#Severity_levels

They should provide enough fine-grained severity levels for most use-cases and are recognized by existing log-parsers. While you have of course the freedom to only implement a subset, e.g. DEBUG, ERROR, EMERGENCY depending on your app's requirements.

Let's standardize on something that's been around for ages instead of coming up with our own standard for every different app we make. Once you start aggregating logs and are trying to detect patterns across different ones it really helps.

It's a 32-bit signed integer type on most legacy platforms. However, that causes your code to suffer from the year 2038 bug. So modern C libraries should be defining it to be a signed 64-bit int instead, which is safe for a few billion years.

As other have said, you want to use either puts or p. Why? Is that magic?

Actually not. A rails console is, under the hood, an IRB, so all you can do in IRB you will be able to do in a rails console. Since for printing in an IRB we use puts, we use the same command for printing in a rails console.

You can actually take a look at the console code in the rails source code. See the require of irb? :)

Perhaps:

> data.frame(aname=NA, bname=NA)[numeric(0), ]
[1] aname bname
<0 rows> (or 0-length row.names)

This worked for me when i have userdefined Interface 'TopSectionListener', its object activitycommander:

  //This method gets called whenever we attach fragment to the activity
@Override
public void onAttach(Context context) {
    super.onAttach(context);
    Activity a=getActivity();
    try {
        if(context instanceof Activity)
           this.activitycommander=(TopSectionListener)a;
    }catch (ClassCastException e){
        throw new ClassCastException(a.toString());}

}

This will get the full container id from within a container:

cat /proc/self/cgroup | grep "cpu:/" | sed 's/\([0-9]\):cpu:\/docker\///g'

Very simple solution. It uses ASCII values and just generates "random" characters in between them.

public static class UsernameTools
{
    public static string GenerateRandomUsername(int length = 10)
    {
        Random random = new Random();
        StringBuilder sbuilder = new StringBuilder();
        for (int x = 0; x < length; ++x)
        {
            sbuilder.Append((char)random.Next(33, 126));
        }
        return sbuilder.ToString();
    }

}

Like this,

if(v1.HasValue)
   v2=v1.Value

In WebKit and Blink-based browsers & All Kind Of Browser use the following CSS :

/* Disable Number Arrow */
input[type=number]::-webkit-inner-spin-button, 
input[type=number]::-webkit-outer-spin-button { 
  -webkit-appearance: none; 
  margin: 0; 
}

Use BufferedReader, you can make it read from standard input like this:

BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));
String line;

while ((line = stdin.readLine()) != null && line.length()!= 0) {
    String[] input = line.split(" ");
    if (input.length == 2) {
        System.out.println(calculateAnswer(input[0], input[1]));
    }
}

This is how I do :

<div class="jumbotron" style="background: url(img/bg.jpg) no-repeat center center fixed; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover;">_x000D_
  <h1>Hello</h1>_x000D_
</div>

I don't think desc takes an na.rm argument... I'm actually surprised it doesn't throw an error when you give it one. If you just want to remove NAs, use na.omit (base) or tidyr::drop_na:

outcome.df %>%
  na.omit() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

library(tidyr)
outcome.df %>%
  drop_na() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

If you only want to remove NAs from the HeartAttackDeath column, filter with is.na, or use tidyr::drop_na:

outcome.df %>%
  filter(!is.na(HeartAttackDeath)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

outcome.df %>%
  drop_na(HeartAttackDeath) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

As pointed out at the dupe, complete.cases can also be used, but it's a bit trickier to put in a chain because it takes a data frame as an argument but returns an index vector. So you could use it like this:

outcome.df %>%
  filter(complete.cases(.)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

You could use a bit of jQuery:

$('input:radio').click(function(){
    $('label#' + $(this).attr('id')).toggleClass('checkedClass'); // checkedClass is defined in your CSS
});

You'd need to make sure your checked radio buttons have the correct class on page load as well.

Prior to PHP 5.4:

$myArray = array();

PHP 5.4 and higher

$myArray = [];

Use ChangeDetectorRef.detectChanges() to tell Angular to run a change detection when you edit a nested object (that it misses with its dirty checking).

Try this code,

public void ConnectToAccess()
{
    System.Data.OleDb.OleDbConnection conn = new 
        System.Data.OleDb.OleDbConnection();
    // TODO: Modify the connection string and include any
    // additional required properties for your database.
    conn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;" +
        @"Data source= C:\Documents and Settings\username\" +
        @"My Documents\AccessFile.mdb";
    try
    {
        conn.Open();
        // Insert code to process data.
    }
        catch (Exception ex)
    {
        MessageBox.Show("Failed to connect to data source");
    }
    finally
    {
        conn.Close();
    }
}

NPM shrinkwrap offers a nice solution to this problem. It allows us to override that version of a particular dependency of a particular sub-module.

Essentially, when you run npm install, npm will first look in your root directory to see whether a npm-shrinkwrap.json file exists. If it does, it will use this first to determine package dependencies, and then falling back to the normal process of working through the package.json files.

To create an npm-shrinkwrap.json, all you need to do is

 npm shrinkwrap --dev

code:

{
  "dependencies": {
    "grunt-contrib-connect": {
      "version": "0.3.0",
      "from": "[email protected]",
      "dependencies": {
        "connect": {
          "version": "2.8.1",
          "from": "connect@~2.7.3"
        }
      }
    }
  }
}

For example, your remote host is example.com and remote login name is user1:

scp [email protected]:/path/to/file /path/to/store/file

This feature is called designated initializers. It is an addition to the C99 standard. However, this feature was left out of the C++11. According to The C++ Programming Language, 4th edition, Section 44.3.3.2 (C Features Not Adopted by C++):

A few additions to C99 (compared with C89) were deliberately not adopted in C++:

[1] Variable-length arrays (VLAs); use vector or some form of dynamic array

[2] Designated initializers; use constructors

The C99 grammar has the designated initializers [See ISO/IEC 9899:2011, N1570 Committee Draft - April 12, 2011]

6.7.9 Initialization

initializer:
    assignment-expression
    { initializer-list }
    { initializer-list , }
initializer-list:
    designation_opt initializer
    initializer-list , designationopt initializer
designation:
    designator-list =
designator-list:
    designator
    designator-list designator
designator:
    [ constant-expression ]
    . identifier

On the other hand, the C++11 does not have the designated initializers [See ISO/IEC 14882:2011, N3690 Committee Draft - May 15, 2013]

8.5 Initializers

initializer:
    brace-or-equal-initializer
    ( expression-list )
brace-or-equal-initializer:
    = initializer-clause
    braced-init-list
initializer-clause:
    assignment-expression
    braced-init-list
initializer-list:
    initializer-clause ...opt
    initializer-list , initializer-clause ...opt
braced-init-list:
    { initializer-list ,opt }
    { }

In order to achieve the same effect, use constructors or initializer lists:

input type=image will do it for you.

OK, here's what we do: open the file, read it line by line, and split it by tabs. Then we grab the second integer and loop through the rest to find the path.

StreamReader reader = File.OpenText("filename.txt");
string line;
while ((line = reader.ReadLine()) != null) 
{
    string[] items = line.Split('\t');
    int myInteger = int.Parse(items[1]);   // Here's your integer.

    // Now let's find the path.
    string path = null;
    foreach (string item in items) 
    {
        if (item.StartsWith("item\\") && item.EndsWith(".ddj"))
            path = item;
    }

    // At this point, `myInteger` and `path` contain the values we want
    // for the current line. We can then store those values or print them,
    // or anything else we like.
}

I would prefer generally foreach when I don't need making arithmetic operations with their indices.

for (int[] x : array)
{
   for (int y : x)
   {
        System.out.print(y + " ");
   }
   System.out.println();
}

You could parse the JSON to an object, then create your malformed JSON from the ajavscript object. This may not be the best performance-wise, tho.

Otherwise, if you only need to make very small changes to the string, just treat it as a string, and mangle it using standard javascript.

v = alli.max()
index = alli.argmax()
x, y = index/8, index%8

Very informative answer from @stej, but here is a short answer: Among other options, you have 3 simple options to format [System.DateTime] stored in a variable:

1. Pass the variable to the Get-Date cmdlet: Get-Date -Format "HH:mm" $date

2. Use toString() method: $date.ToString("HH:mm")

3. Use Composite formatting: "{0:HH:mm}" -f $date

Here is some code that will give you the general idea.

You need to create a custom ClientHttpRequestFactory in order to trust the certificate. It looks like this:

final ClientHttpRequestFactory clientHttpRequestFactory =
        new MyCustomClientHttpRequestFactory(org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER, serverInfo);
    restTemplate.setRequestFactory(clientHttpRequestFactory);

This is the implementation for MyCustomClientHttpRequestFactory:

public class MyCustomClientHttpRequestFactory  extends SimpleClientHttpRequestFactory {

private final HostnameVerifier hostNameVerifier;
private final ServerInfo serverInfo;

public MyCustomClientHttpRequestFactory (final HostnameVerifier hostNameVerifier,
    final ServerInfo serverInfo) {
    this.hostNameVerifier = hostNameVerifier;
    this.serverInfo = serverInfo;
}

@Override
protected void prepareConnection(final HttpURLConnection connection, final String httpMethod)
    throws IOException {
    if (connection instanceof HttpsURLConnection) {
        ((HttpsURLConnection) connection).setHostnameVerifier(hostNameVerifier);
        ((HttpsURLConnection) connection).setSSLSocketFactory(initSSLContext()
            .getSocketFactory());
    }
    super.prepareConnection(connection, httpMethod);
}

private SSLContext initSSLContext() {
    try {
        System.setProperty("https.protocols", "TLSv1");

        // Set ssl trust manager. Verify against our server thumbprint
        final SSLContext ctx = SSLContext.getInstance("TLSv1");
        final SslThumbprintVerifier verifier = new SslThumbprintVerifier(serverInfo);
        final ThumbprintTrustManager thumbPrintTrustManager =
            new ThumbprintTrustManager(null, verifier);
        ctx.init(null, new TrustManager[] { thumbPrintTrustManager }, null);
        return ctx;
    } catch (final Exception ex) {
        LOGGER.error(
            "An exception was thrown while trying to initialize HTTP security manager.", ex);
        return null;
    }
}

In this case my serverInfo object contains the thumbprint of the server. You need to implement the TrustManager interface to get the SslThumbprintVerifier or any other method you want to verify your certificate (you can also decide to also always return true).

The value org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER allows all host names. If you need to verify the host name, you will need to implement it differently.

I'm not sure about the user and password and how you implemented it. Often, you need to add a header to the restTemplate named Authorization with a value that looks like this: Base: <encoded user+password>. The user+password must be Base64 encoded.

I've used it in code before, though only to interface with legacy code. This was a Mac OS X Cocoa application that needed to load preference files from an earlier, Carbon version (which was itself backwards-compatible with the original M68k System 6.5 version...you get the idea). The preference files in the original version were a binary dump of a configuration structure, that used the #pragma pack(1) to avoid taking up extra space and saving junk (i.e. the padding bytes that would otherwise be in the structure).

The original authors of the code had also used #pragma pack(1) to store structures that were used as messages in inter-process communication. I think the reason here was to avoid the possibility of unknown or changed padding sizes, as the code sometimes looked at a specific portion of the message struct by counting a number of bytes in from the start (ewww).

Because I kept finding this page when looking for a way to remove a field using MongoEngine, I guess it might be helpful to post the MongoEngine way here too:

Example.objects.all().update(unset__tags__words=1)

Try to use DateTime.ParseExact method, in which you can specify both of datetime mask and original parsed string. You can read about it here: MSDN: DateTime.ParseExact

Per Arvand:
Eclipse: Simply type android.R.layout.simple_list_item_1 somewhere in code, hold Ctrl, hover over simple_list_item_1, and from the dropdown that appears select Open declaration in layout/simple_list_item_1.xml. It'll direct you to the contents of the XML.

From there, if you then hover over the resulting simple_list_item_1.xml tab in the Editor, you'll see the file is located at C:\Data\applications\Android\android-sdk\platforms\android-19\data\res\layout\simple_list_item_1.xml (or equivalent location for your installation).

For me was php version from mac instead of MAMP, PATH variable on .bash_profile was wrong. I just prepend the MAMP PHP bin folder to the $PATH env variable. For me was:

/Applications/mampstack-7.1.21-0/php/bin

1. In terminal run vim ~/.bash_profile to open ~/.bash_profile

2. Type i to be able to edit the file, add the bin directory as PATH variable on the top to the file:

   export PATH="/Applications/mampstack-7.1.21-0/php/bin/:$PATH"

3. Hit ESC, Type :wq, and hit Enter

4. In Terminal run source ~/.bash_profile
5. In Terminal type which php, output should be the path to MAMP PHP install.

That happens because you're setting the src of the ImageView instead of the background.

Use this instead:

qImageView.setBackgroundResource(R.drawable.thumbs_down);

Here's a thread that talks about the differences between the two methods.

1. Object* o; o = new Object();

2. Object* o = new Object();

Both these statement creates the object in the heap memory since you are creating the object using "new".

To be able to make the object creation happen in the stack, you need to follow this:

Object o;
Object *p = &o;

Selenium provides a convenient Select class to work with select -> option constructs:

from selenium import webdriver
from selenium.webdriver.support.ui import Select

driver = webdriver.Firefox()
driver.get('url')

select = Select(driver.find_element_by_id('fruits01'))

# select by visible text
select.select_by_visible_text('Banana')

# select by value 
select.select_by_value('1')

See also:

• What is the correct way to select an using Selenium's Python WebDriver?

Remove space between classes in css selector:

driver.find_element_by_css_selector('.button .c_button .s_button').click()
#                                           ^         ^

=>

driver.find_element_by_css_selector('.button.c_button.s_button').click()

Used the build-helper-maven-plugin from the post - and update src/main/generated. And mvn clean compile works on my ../common/src/main/java, or on ../common, so kept the latter. Then yes, confirming that IntelliJ IDEA (ver 10.5.2) level of the compilation failed as David Phillips mentioned. The issue was that IDEA did not add another source root to the project. Adding it manually solved the issue. It's not nice as editing anything in the project should come from maven and not from direct editing of IDEA's project options. Yet I will be able to live with it until they support build-helper-maven-plugin directly such that it will auto add the sources.

Then needed another workaround to make this work though. Since each time IDEA re-imported maven settings after a pom change me newly added source was kept on module, yet it lost it's Source Folders selections and was useless. So for IDEA - need to set these once:

• Select - Project Settings / Maven / Importing / keep source and test folders on reimport.
• Add - Project Structure / Project Settings / Modules / {Module} / Sources / Add Content Root.

Now keeping those folders on import is not the best practice in the world either, ..., but giving it a try.

You can this query:

pip install image 

I had pillow installed, and still, I got the error that you mentioned. But after I executed the above command, the error vanished. And My program worked perfectly.

How a character is represented is up to the renderer, but the server may also strip out certain characters before sending the document.

You can also have untitled YouTube videos like https://www.youtube.com/watch?v=dmBvw8uPbrA by using the Unicode character ZERO WIDTH NON-JOINER (U+200C), or ‌ in HTML. The code block below should contain that character:

It looks like you are trying to parse each line. You've been shown by another answer how to use getline in a loop to seperate each line. The other tool you are going to want is istringstream, to seperate each token.

std::string line;
while(std::getline(file, line))
{
    std::istringstream iss(line);
    std::string token;
    while (iss >> token)
    {
        // do something with token
    }
}

Often, I've found that the solution to this problem can be fixed by disabling and then enabling the Wifi hardware. I've made a script to do this automatically instead of doing it manually by going to the device manager. You can find it here

I've tried different numbers, and it always acts as if the 0s aren't there and sorts the numbers correctly otherwise. Anyone know why?

You're getting a lexicographical sort (e.g. convert objects to strings, and sort them in dictionary order), which is the default sort behavior in Javascript:

https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/sort

array.sort([compareFunction])

Parameters

compareFunction

Specifies a function that defines the sort order. If omitted, the array is sorted lexicographically (in dictionary order) according to the string conversion of each element.

In the ECMAscript specification (the normative reference for the generic Javascript), ECMA-262, 3rd ed., section 15.4.4.11, the default sort order is lexicographical, although they don't come out and say it, instead giving the steps for a conceptual sort function that calls the given compare function if necessary, otherwise comparing the arguments when converted to strings:

13. If the argument comparefn is undefined, go to step 16.
14. Call comparefn with arguments x and y.
15. Return Result(14).
16. Call ToString(x).
17. Call ToString(y).
18. If Result(16) < Result(17), return -1.
19. If Result(16) > Result(17), return 1.
20. Return +0.

Not sure if this answer the question or going to help....

$dt = '6/26/1970' ; // or // '6.26.1970' ;

$dt = preg_replace("([.]+)", "/", $dt);

$test_arr  = explode('/', $dt);

if (checkdate($test_arr[0], $test_arr[1], $test_arr[2]) && preg_match("/[0-9]{1,2}\/[0-9]{1,2}\/[0-9]{4}/", $dt))

     { echo(date('Y-m-d', strtotime("$dt")) . "<br>"); }

   else

     { echo "no good...format must be in mm/dd/yyyy"; }

Now I've got the same problem, and for some reasons I decided to avoid decorators, factories and metaclasses. I did it like this:

Main file

def _alt(func):
    import functools
    @functools.wraps(func)
    def init(self, *p, **k):
        if hasattr(self, "parent_initialized"):
            return
        else:
            self.parent_initialized = True
            func(self, *p, **k)

    return init


class Parent:
    # Empty dictionary, shouldn't ever be filled with anything else
    parent_cache = {}

    def __new__(cls, n, *args, **kwargs):

        # Checks if object with this ID (n) has been created
        if n in cls.parent_cache:

            # It was, return it
            return cls.parent_cache[n]

        else:

            # Check if it was modified by this function
            if not hasattr(cls, "parent_modified"):
                # Add the attribute
                cls.parent_modified = True
                cls.parent_cache = {}

                # Apply it
                cls.__init__ = _alt(cls.__init__)

            # Get the instance
            obj = super().__new__(cls)

            # Push it to cache
            cls.parent_cache[n] = obj

            # Return it
            return obj

Example classes

class A(Parent):

    def __init__(self, n):
        print("A.__init__", n)


class B(Parent):

    def __init__(self, n):
        print("B.__init__", n)

In use

>>> A(1)
A.__init__ 1  # First A(1) initialized 
<__main__.A object at 0x000001A73A4A2E48>
>>> A(1)      # Returned previous A(1)
<__main__.A object at 0x000001A73A4A2E48>
>>> A(2)
A.__init__ 2  # First A(2) initialized
<__main__.A object at 0x000001A7395D9C88>
>>> B(2)
B.__init__ 2  # B class doesn't collide with A, thanks to separate cache
<__main__.B object at 0x000001A73951B080>

• Warning: You shouldn't initialize Parent, it will collide with other classes - unless you defined separate cache in each of the children, that's not what we want.
• Warning: It seems a class with Parent as grandparent behaves weird. [Unverified]

Try it online!

I always go for the second method (using the GString template), though when there are more than a couple of parameters like you have, I tend to wrap them in ${X} as I find it makes it more readable.

Running some benchmarks (using Nagai Masato's excellent GBench module) on these methods also shows templating is faster than the other methods:

@Grab( 'com.googlecode.gbench:gbench:0.3.0-groovy-2.0' )
import gbench.*

def (foo,bar,baz) = [ 'foo', 'bar', 'baz' ]
new BenchmarkBuilder().run( measureCpuTime:false ) {
  // Just add the strings
  'String adder' {
    foo + bar + baz
  }
  // Templating
  'GString template' {
    "$foo$bar$baz"
  }
  // I find this more readable
  'Readable GString template' {
    "${foo}${bar}${baz}"
  }
  // StringBuilder
  'StringBuilder' {
    new StringBuilder().append( foo )
                       .append( bar )
                       .append( baz )
                       .toString()
  }
  'StringBuffer' {
    new StringBuffer().append( foo )
                      .append( bar )
                      .append( baz )
                      .toString()
  }
}.prettyPrint()

That gives me the following output on my machine:

Environment

String adder               539
GString template           245
Readable GString template  244
StringBuilder              318
StringBuffer               370

So with readability and speed in it's favour, I'd recommend templating ;-)

NB: If you add toString() to the end of the GString methods to make the output type the same as the other metrics, and make it a fairer test, StringBuilder and StringBuffer beat the GString methods for speed. However as GString can be used in place of String for most things (you just need to exercise caution with Map keys and SQL statements), it can mostly be left without this final conversion

Adding these tests (as it has been asked in the comments)

  'GString template toString' {
    "$foo$bar$baz".toString()
  }
  'Readable GString template toString' {
    "${foo}${bar}${baz}".toString()
  }

Now we get the results:

String adder                        514
GString template                    267
Readable GString template           269
GString template toString           478
Readable GString template toString  480
StringBuilder                       321
StringBuffer                        369

So as you can see (as I said), it is slower than StringBuilder or StringBuffer, but still a bit faster than adding Strings...

But still lots more readable.

Edit after comment by ruralcoder below

Updated to latest gbench, larger strings for concatenation and a test with a StringBuilder initialised to a good size:

@Grab( 'org.gperfutils:gbench:0.4.2-groovy-2.1' )

def (foo,bar,baz) = [ 'foo' * 50, 'bar' * 50, 'baz' * 50 ]
benchmark {
  // Just add the strings
  'String adder' {
    foo + bar + baz
  }
  // Templating
  'GString template' {
    "$foo$bar$baz"
  }
  // I find this more readable
  'Readable GString template' {
    "${foo}${bar}${baz}"
  }
  'GString template toString' {
    "$foo$bar$baz".toString()
  }
  'Readable GString template toString' {
    "${foo}${bar}${baz}".toString()
  }
  // StringBuilder
  'StringBuilder' {
    new StringBuilder().append( foo )
                       .append( bar )
                       .append( baz )
                       .toString()
  }
  'StringBuffer' {
    new StringBuffer().append( foo )
                      .append( bar )
                      .append( baz )
                      .toString()
  }
  'StringBuffer with Allocation' {
    new StringBuffer( 512 ).append( foo )
                      .append( bar )
                      .append( baz )
                      .toString()
  }
}.prettyPrint()

gives

Since SQL 2012 you can run the following statement:

Exec sp_describe_first_result_set @tsql= N'Select * from <yourtable>'

If you enter a complex select statement (joins, subselects, etc), it will give you the definition of the result set. This is very handy, if you need to create a new table (or temp table) and you don't want to check every single field definition manually.

https://docs.microsoft.com/en-us/sql/relational-databases/system-stored-procedures/sp-describe-first-result-set-transact-sql

You can do this without a regular expression. Simply cast your HTML string to an HTML node using document.createElement(), find all scripts with element.getElementsByTagName('script'), and then just remove() them!

Fun fact: SO's demo does not like it when you create an element with a <script> tag! The snippet below will not run, but it does work at: Full Working Demo at JSBin.com.

var el = document.createElement( 'html' );
el.innerHTML = "<p>Valid paragraph.</p><p>Another valid paragraph.</p><script>Dangerous scripting!!!</script><p>Last final paragraph.</p>";

var scripts = el.getElementsByTagName( 'script' ); // Live NodeList of your anchor elements

for(var i = 0; i < scripts.length; i++) {
  var script = scripts[i];
  script.remove();
}

console.log(el.innerHTML);

This is a much cleaner solution than a regex, imho.

Besides the session cookie (which is kind of standard), I don't want to use extra cookies.

I found a solution which works for me when building a Single Page Web Application (SPA), with many AJAX requests. Note: I am using server side Java and client side JQuery, but no magic things so I think this principle can be implemented in all popular programming languages.

My solution without extra cookies is simple:

Client Side

Store the CSRF token which is returned by the server after a succesful login in a global variable (if you want to use web storage instead of a global thats fine of course). Instruct JQuery to supply a X-CSRF-TOKEN header in each AJAX call.

The main "index" page contains this JavaScript snippet:

// Intialize global variable CSRF_TOKEN to empty sting. 
// This variable is set after a succesful login
window.CSRF_TOKEN = '';

// the supplied callback to .ajaxSend() is called before an Ajax request is sent
$( document ).ajaxSend( function( event, jqXHR ) {
    jqXHR.setRequestHeader('X-CSRF-TOKEN', window.CSRF_TOKEN);
}); 

Server Side

On successul login, create a random (and long enough) CSRF token, store this in the server side session and return it to the client. Filter certain (sensitive) incoming requests by comparing the X-CSRF-TOKEN header value to the value stored in the session: these should match.

Sensitive AJAX calls (POST form-data and GET JSON-data), and the server side filter catching them, are under a /dataservice/* path. Login requests must not hit the filter, so these are on another path. Requests for HTML, CSS, JS and image resources are also not on the /dataservice/* path, thus not filtered. These contain nothing secret and can do no harm, so this is fine.

@WebFilter(urlPatterns = {"/dataservice/*"})
...
String sessionCSRFToken = req.getSession().getAttribute("CSRFToken") != null ? (String) req.getSession().getAttribute("CSRFToken") : null;
if (sessionCSRFToken == null || req.getHeader("X-CSRF-TOKEN") == null || !req.getHeader("X-CSRF-TOKEN").equals(sessionCSRFToken)) {
    resp.sendError(401);
} else
    chain.doFilter(request, response);
}   

As of Hive version 0.14.0: INSERT...VALUES, UPDATE, and DELETE are now available with full ACID support.

INSERT ... VALUES Syntax:

INSERT INTO TABLE tablename [PARTITION (partcol1[=val1], partcol2[=val2] ...)] VALUES values_row [, values_row ...]

Where values_row is: ( value [, value ...] ) where a value is either null or any valid SQL literal

UPDATE Syntax:

UPDATE tablename SET column = value [, column = value ...] [WHERE expression]

DELETE Syntax:

DELETE FROM tablename [WHERE expression]

Additionally, from the Hive Transactions doc:

If a table is to be used in ACID writes (insert, update, delete) then the table property "transactional" must be set on that table, starting with Hive 0.14.0. Without this value, inserts will be done in the old style; updates and deletes will be prohibited.

I would suggest using the directives like the following:

        static void Main(string[] args)
        {
#if DEBUG
            args = new[] { "A" };
#endif

            Console.WriteLine(args[0]);
        }

Good luck!
