yes there is. it is called corona sdk!

I fixed it by re-adding the key to my ssh-agent.

with the following command:

ssh-add ~/.ssh/path_to_private_key_you_generated

For some reasons it was gone.

If you need to frequently use LIKE, you can simplify the problem a bit. A custom method like () can be created in the model that inherits the Eloquent ORM:

public  function scopeLike($query, $field, $value){
        return $query->where($field, 'LIKE', "%$value%");
}

So then you can use this method in such way:

User::like('name', 'Tomas')->get();

I have a solution from a while ago that I kept improving. Also searches within XML columns if told to do so, or searches integer values if providing a integer only string.

/* Reto Egeter, fullparam.wordpress.com */

SET @FullRowResult = 1
SET @FullRowResultRows = 3
SET @SearchStrTableName = NULL /* NULL for all tables, uses LIKE syntax */
SET @SearchStrColumnName = NULL /* NULL for all columns, uses LIKE syntax */

Other words printf absent in python... I'm surprised! Best code is

def printf(format, *args):
    sys.stdout.write(format % args)

Because of this form allows not to print \n. All others no. That's why print is bad operator. And also you need write args in special form. There is no disadvantages in function above. It's a standard usual form of printf function.

To add to Mehrdad answer ,

namespace Math
{
    class Matrix
    {
       public:

       [...]


    }   
    std::ostream& operator<< (std::ostream& stream, const Math::Matrix& matrix);
}

In your implementation

std::ostream& operator<<(std::ostream& stream, 
                     const Math::Matrix& matrix) {
    matrix.print(stream); //assuming you define print for matrix 
    return stream;
 }

Another possible mistake that could produce this problem,

Make sure you didn't included bootstrap.js script more than once in your page!

Use the following:

bower install --save git://github.com/USER/REPOS_NAME.git

More here: http://bower.io/#getting-started

UPDATE 2018 MAY:

Alternatively, you can embed Edge browser, but only targetting windows 10.

Here is the solution.

You're using message.Length which returns the number of characters in the string, but you should be using the nubmer of bytes to read. You should use something like:

byte[] messageBytes = uniEncoding.GetBytes(message);
stringAsStream.Write(messageBytes, 0, messageBytes.Length);

You're then reading a single byte and expecting to get a character from it just by casting to char. UnicodeEncoding will use two bytes per character.

As Justin says you're also not seeking back to the beginning of the stream.

Basically I'm afraid pretty much everything is wrong here. Please give us the bigger picture and we can help you work out what you should really be doing. Using a StreamWriter to write and then a StreamReader to read is quite possibly what you want, but we can't really tell from just the brief bit of code you've shown.

I think this syntax has not been mentionned yet (in the case you want a method without arguments) :

class Clazz {
  static <T> T doIt() {
    // shake that booty
  }
}

And the call :

String str = Clazz.<String>doIt();

Hope this help someone.

You can also use pandas.Series.isin although it's a little bit longer than 'a' in s.values:

In [2]: s = pd.Series(list('abc'))

In [3]: s
Out[3]: 
0    a
1    b
2    c
dtype: object

In [3]: s.isin(['a'])
Out[3]: 
0    True
1    False
2    False
dtype: bool

In [4]: s[s.isin(['a'])].empty
Out[4]: False

In [5]: s[s.isin(['z'])].empty
Out[5]: True

But this approach can be more flexible if you need to match multiple values at once for a DataFrame (see DataFrame.isin)

>>> df = DataFrame({'A': [1, 2, 3], 'B': [1, 4, 7]})
>>> df.isin({'A': [1, 3], 'B': [4, 7, 12]})
       A      B
0   True  False  # Note that B didn't match 1 here.
1  False   True
2   True   True

So I figured out a way to do this effectively. For my particular project I'm building an iPad website so I knew exactly what the pixel X/Y value would be to reach the edge of the screen. Your thisX and thisY values will vary.

Since the popovers are being placed by inline styling anyway, I simply grab the left and top values for each link to decide which direction the popover should be. This is done by appending html5 data- values that .popover() uses upon execution.

if ($('.infopoint').length>0){
    $('.infopoint').each(function(){
        var thisX = $(this).css('left').replace('px','');
        var thisY = $(this).css('top').replace('px','');
        if (thisX > 515)
            $(this).attr('data-placement','left');
        if (thisX < 515)
            $(this).attr('data-placement','right');
        if (thisY > 480)
            $(this).attr('data-placement','top');
        if (thisY < 110)
            $(this).attr('data-placement','bottom');
    });
    $('.infopoint').popover({
        trigger:'hover',
        animation: false,
        html: true
    });
}

Any comments/improvements are welcome but this gets the job done if you're willing to put the values in manually.

Use data type LONGBLOB instead of BLOB in your database table.

I know this post is old but...

I was able to do this, my problem was that I forgot to make my property static.

public static class MyStaticClass
{
    private static NonStaticObject _myObject = new NonStaticObject();

    //property
    public static NonStaticObject MyObject
    {
        get { return _myObject; }
        set { _myObject = value; }
    }
}

Put in gradle.properties file the following code line:

org.gradle.java.home=C:\\Program Files\\Java\\jdk1.8.0_45

Example image

I have query,

$("#login-button").click(function(e){ alert("hiii");

        var username = $("#username-field").val();
        var password = $("#username-field").val();

        alert(username);
        alert("password" + password);



        var markers = { "userName" : "admin","password" : "admin123"};
        $.ajax({
            type: "POST",
            url: url,
            // The key needs to match your method's input parameter (case-sensitive).
            data: JSON.stringify(markers),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function(data){alert("got the data"+data);},
            failure: function(errMsg) {
                alert(errMsg);
            }
        });

    });

I'm posting the the login details in json and getting a string as "Success",but I'm not getting the response.

You can use

if errorlevel 1 echo Unsuccessful

in some cases. This depends on the last command returning a proper exit code. You won't be able to tell that there is anything wrong if your program returns normally even if there was an abnormal condition.

Caution with programs like Robocopy, which require a more nuanced approach, as the error level returned from that is a bitmask which contains more than just a boolean information and the actual success code is, AFAIK, 3.

update: 31 Oct 2018, Still usable on laravel 5.7 https://laravel.com/docs/5.7/migrations#modifying-columns

To make some change to existing db, you can modify column type by using change() in migration.

This is what you could do

Schema::table('orders', function ($table) {
    $table->string('category_id')->change();
});

please note you need to add doctrine/dbal dependency to composer.json for more information you can find it here http://laravel.com/docs/5.1/migrations#modifying-columns

Alternative:(Using Sierra or High Sierra and Ionic)

1. Copy and Paste the App Store icon to the desktop.
2. Open the image. Click File Menu->Duplicate.
3. Save it by unticking the Alpha channel.
4. Replace the current App Store icon with this one.
5. Validate and upload.

Use explicit injection. No other approach will allow you for instance to run tests in parallel in the same JVM.

Patterns that use anything classloader wide like static log binder or messing with environmental thinks like logback.XML are bust when it comes to testing.

Consider the parallelized tests I mention , or consider the case where you want to intercept logging of component A whose construction is hidden behind api B. This latter case is easy to deal with if you are using a dependency injected loggerfactory from the top, but not if you inject Logger as there no seam in this assembly at ILoggerFactory.getLogger.

And its not all about unit testing either. Sometimes we want integration tests to emit logging. Sometimes we don't. Someone's we want some of the integration testing logging to be selectively suppressed, eg for expected errors that would otherwise clutter the CI console and confuse. All easy if you inject ILoggerFactory from the top of your mainline (or whatever di framework you might use)

So...

Either inject a reporter as suggested or adopt a pattern of injecting the ILoggerFactory. By explicit ILoggerFactory injection rather than Logger you can support many access/intercept patterns and parallelization.

ManagementFactory.getThreadMXBean().getThreadCount() doesn't limit itself to thread groups as Thread.activeCount() does.

Here are the examples of Filter, map and reduce functions.

numbers = [10,11,12,22,34,43,54,34,67,87,88,98,99,87,44,66]

//Filter

oddNumbers = list(filter(lambda x: x%2 != 0, numbers))

print(oddNumbers)

//Map

multiplyOf2 = list(map(lambda x: x*2, numbers))

print(multiplyOf2)

//Reduce

The reduce function, since it is not commonly used, was removed from the built-in functions in Python 3. It is still available in the functools module, so you can do:

from functools import reduce

sumOfNumbers = reduce(lambda x,y: x+y, numbers)

print(sumOfNumbers)

As other people suggested, you need to use a combobox. However, most tutorials show you how to set up just one combobox and the process is quite tedious.

As I faced this problem before when entering a large amount of data from a list, I can suggest you use this autocomplete add-in . It helps you create the combobox on any cells you select and you can define a list to appear in the dropdown.

//Representation of table
<div class="search-table-outter">
<table class="table table-responsive search-table inner">
</table>
</div>

//Css to make Horizontal Dropdown

<style>

    .search-table{table-layout: auto; margin:40px auto 0px auto; }
    .search-table, td, th {
        border-collapse: collapse;
    }
th{padding:20px 7px; font-size:15px; color:#444;}
td{padding:5px 10px; height:35px;}
    .search-table-outter { overflow-x: scroll; }
th, td { min-width: 200px; }


</style>

Depending on your definition of shortly, you could use one of the following options:

• try: int(your_input); except ValueError: # ...
• your_input.isdigit()
• use a regex
• use parse which is kind of the opposite of format

If you're using Xfce (or LXDE) instead of Gnome, there's an equivalent tool: Gigolo.
I suppose, but not sure, it can be installed also on other desktop environments.
It supports FTP, SSH and WebDAV and it is quite intuitive to use: just click on Connect, choose the protocol, fill the parameters and go. You can save the connections for later use.

Java String class has a built-in-constructor for converting byte array to string.

byte[] byteArray = new byte[] {87, 79, 87, 46, 46, 46};

String value = new String(byteArray, "UTF-8");

These are class stereotypes used in analysis.

• boundary classes are ones at the boundary of the system - the classes that you or other systems interact with

• entity classes classes are your typical business entities like "person" and "bank account"

• control classes implement some business logic or other

yes you can use

<property name="hbm2ddl.auto" value="create"/>

yum install nmap-ncat.x86_64

resolved my problem

It looks like regex /\r\n|\r|\n/ handles CR, LF, and CRLF line endings, their mixed sequences, and keeps all the empty lines inbetween. Try that!

    function splitLines(t) { return t.split(/\r\n|\r|\n/); }

    // single newlines
    console.log(splitLines("AAA\rBBB\nCCC\r\nDDD"));
    // double newlines
    console.log(splitLines("EEE\r\rFFF\n\nGGG\r\n\r\nHHH"));
    // mixed sequences
    console.log(splitLines("III\n\r\nJJJ\r\r\nKKK\r\n\nLLL\r\n\rMMM"));

You should get these arrays as a result:

[ "AAA", "BBB", "CCC", "DDD" ]
[ "EEE", "", "FFF", "", "GGG", "", "HHH" ]
[ "III", "", "JJJ", "", "KKK", "", "LLL", "", "MMM" ]

You can also teach that regex to recognize other legit Unicode line terminators by adding |\xHH or |\uHHHH parts, where H's are hexadecimal digits of the additional terminator character codepoint (as seen in Wikipedia article as U+HHHH).

the rule of thumb for throwing exceptions is pretty simple. you do so when your code has entered into an UNRECOVERABLE INVALID state. if data is compromised or you cannot wind back the processing that occurred up to the point then you must terminate it. indeed what else can you do? your processing logic will eventually fail elsewhere. if you can recover somehow then do that and do not throw exception.

in your particular case if you were forced to do something silly like accept money withdrawal and only then check user/pasword you should terminate the process by throwing an exception to notify that something bad has happened and prevent further damage.

Please understand the code at your own effort :D This is my draft code and its already working :) Here's the screenshot.

While you are using synchronized(this) you are using the class instance as a lock itself. This means that while lock is acquired by thread 1, the thread 2 should wait.

Suppose the following code:

public void method1() {
    // do something ...
    synchronized(this) {
        a ++;      
    }
    // ................
}


public void method2() {
    // do something ...
    synchronized(this) {
        b ++;      
    }
    // ................
}

Method 1 modifying the variable a and method 2 modifying the variable b, the concurrent modification of the same variable by two threads should be avoided and it is. BUT while thread1 modifying a and thread2 modifying b it can be performed without any race condition.

Unfortunately, the above code will not allow this since we are using the same reference for a lock; This means that threads even if they are not in a race condition should wait and obviously the code sacrifices concurrency of the program.

The solution is to use 2 different locks for two different variables:

public class Test {

    private Object lockA = new Object();
    private Object lockB = new Object();

    public void method1() {
        // do something ...
        synchronized(lockA) {
            a ++;      
        }
        // ................
    }


    public void method2() {
        // do something ...
        synchronized(lockB) {
            b ++;      
        }
        // ................
    }

}

The above example uses more fine grained locks (2 locks instead one (lockA and lockB for variables a and b respectively) and as a result allows better concurrency, on the other hand it became more complex than the first example ...

Try std::find

vector<int>::iterator it = std::find(v.begin(), v.end(), 123);

If($email->count()>0)
<h1>Email exist, please make new email address</h1>
endif

There are a lot of things to consider when validating a phone number if you really think about it. (especially international) so using a package is better than the accepted answer by far, and if you want something simple like a regex I would suggest using something better than what @SlateEntropy suggested. (something like A comprehensive regex for phone number validation)

Sets require their items to be hashable. Out of types predefined by Python only the immutable ones, such as strings, numbers, and tuples, are hashable. Mutable types, such as lists and dicts, are not hashable because a change of their contents would change the hash and break the lookup code.

Since you're sorting the list anyway, just place the duplicate removal after the list is already sorted. This is easy to implement, doesn't increase algorithmic complexity of the operation, and doesn't require changing sublists to tuples:

def uniq(lst):
    last = object()
    for item in lst:
        if item == last:
            continue
        yield item
        last = item

def sort_and_deduplicate(l):
    return list(uniq(sorted(l, reverse=True)))

function parseJsonDate(jsonDate) {

    var fullDate = new Date(parseInt(jsonDate.substr(6)));
    var twoDigitMonth = (fullDate.getMonth() + 1) + ""; if (twoDigitMonth.length == 1) twoDigitMonth = "0" + twoDigitMonth;

    var twoDigitDate = fullDate.getDate() + ""; if (twoDigitDate.length == 1) twoDigitDate = "0" + twoDigitDate;
    var currentDate = twoDigitMonth + "/" + twoDigitDate + "/" + fullDate.getFullYear();

    return currentDate;
};

//Use this function

var objDate=parseJsonDate("\/Date(1443812400000)\/");
alert(objDate);

                        list_of_calendar.setAdapter(adapter);
                    }
                }
                catch (Exception e) 
                {
                    e.printStackTrace();
                }
            }
            else
            {
                Toast.makeText(Calendar.this, "Network Problem", Toast.LENGTH_LONG).show();
            }
        }

    }

and execute it in OnCreate Method like new GetData().execute();

where Calendar is my calendarActivity and i have also created a CalendarAdapter to set these values to a list view.

I happen to have implemented it, and it works in most cases. Since it is long, I put it in a file here.

The idea is to find the location of the class source file which is available in most cases (a known exception are JVM class files -- as far as I've tested). If the code is in a directory, scan through all files and only spot class files. If the code is in a JAR file, scan all entries.

This method can only be used when:

1. You have a class that is in the same package you want to discover, This class is called a SeedClass. For example, if you want to list all classes in 'java.io', the seed class may be java.io.File.

2. Your classes are in a directory or in a JAR file it has source file information (not source code file, but just source file). As far as I've tried, it work almost 100% except the JVM class (those classes come with the JVM).

3. Your program must have permission to access ProtectionDomain of those classes. If your program is loaded locally, there should be no problem.

I've tested the program only for my regular usage, so it may still have problem.

I hope this helps.

One important thing about git config:

git config has --local, --global and --system levels and corresponding files.

So you may use git config --local, git config --global and git config --system.

By default, git config will write to a local level if no configuration option is passed. Local configuration values are stored in a file that can be found in the repository's .git directory: .git/config

Global level configuration is user-specific, meaning it is applied to an operating system user. Global configuration values are stored in a file that is located in a user's home directory. ~/.gitconfig on Unix systems and C:\Users\<username>\.gitconfig on Windows.

System-level configuration is applied across an entire machine. This covers all users on an operating system and all repositories. The system level configuration file lives in a gitconfig file off the system root path. $(prefix)/etc/gitconfig on Linux systems. On Windows this file can be found in C:\ProgramData\Git\config.

So your option is to find that global .gitconfig file and edit it.

Or you can use git config --global --list.

This is exactly the line what you need.

Just nib. Name the class Nib, with a capital N. For more on naming conventions and other style advice, see PEP 8, the Python style guide.

I would also recommend the Tao Framework. But one additional note:

Take a look at these tutorials: http://www.taumuon.co.uk/jabuka/

You can simply place a forward declaration of your second() function in your main.cpp above main(). If your second.cpp has more than one function and you want all of it in main(), put all the forward declarations of your functions in second.cpp into a header file and #include it in main.cpp.

Like this-

Second.h:

void second();
int third();
double fourth();

main.cpp:

#include <iostream>
#include "second.h"
int main()
{
    //.....
    return 0;
}

second.cpp:

void second()
{
    //...
}

int third()
{ 
    //...
    return foo;
}

double fourth()
{ 
    //...
    return f;
}

Note that: it is not necessary to #include "second.h" in second.cpp. All your compiler need is forward declarations and your linker will do the job of searching the definitions of those declarations in the other files.

Look for an installation subdirectory, likely named eclipse. Under that subdirectory, if you see files like eclipse.ini, icon.xpm and subdirectories like plugins and dropins, remove the subdirectory parent (the one named eclipse).

That will remove your installation except for anything you've set up yourself (like workspaces, projects, etc.).

Hope this helps.

DSM's solution works, but if you wanted a direct equivalent to which you could do (df.columns == name).nonzero()

A note to this:

IE 8.0s emulation only promises to display the page the same. There are subtle differences that might cause functionality to break. I recently had a problem with just that. Where IE 7.0 uses a javascript wrapper-function called "anonymous()" in IE 8.0 the wrapper was named differently.

So do not expect things like JavaScript to "just work", because you turn on emulation.

Laravel 5.2 <= 5.5

    use Carbon\Carbon; // You need to import Carbon
    $current_time = Carbon::now()->toDayDateTimeString(); // Wed, May 17, 2017 10:42 PM
    $current_timestamp = Carbon::now()->timestamp; // Unix timestamp 1495062127

In addition, this is how to change datetime format for given date & time, in blade:

{{\Carbon\Carbon::parse($dateTime)->format('D, d M \'y, H:i')}}

Laravel 5.6 <

$current_timestamp = now()->timestamp;

function isAPrimeNumber(num){
     var counter = 0;
     //loop will go k equals to $num
     for (k = 1; k <= num; k++) {
      //check if the num is divisible by itself and 1
      // `%` modulus gives the reminder of the value, so if it gives the reminder `0` then it is divisible by the value
       if (num % k == 0) {
         //increment counter value 1
         counter  = counter  + 1;
        }
    }
   //if the value of the `counter is 2` then it is a `prime number`
  //A prime number is exactly divisible by 2 times only (itself and 1)
   if (counter == 2) {
     return num + ' is a Prime Number';
   }else{
    return num + ' is nota Prime Number';
   }
 }

Now call isAPrimeNumber() function by passing a value.

var resp = isAPrimeNumber(5);
console.log(resp);

Output:

5 is a Prime Number

I managed to solve this in the Request handling code following advice from 'monsur'.

string origin = WebOperationContext.Current.IncomingRequest.Headers.Get("Origin");

WebOperationContext.Current.OutgoingResponse.Headers.Add("Access-Control-Allow-Origin", origin);

I know this question is old, but I tried all of the above and it didn't help me escape the character "@" in ASP.NET full framework (MVC 5) inside a URL. Based on Terje Solem's answer though, the UTF-8 code %40 worked for me. this is the original URL I was trying to reach:

https://unpkg.com/@google/[email protected]/dist/markerclustererplus.min.js

and with with the code in it:

https://unpkg.com/%40google/[email protected]/dist/markerclustererplus.min.js

Although the best width may by 1024 you'll have to adjust height for account for various browser settings (navigation toolbar, bookmark toolbar, status toolbar, etc) and account for taskbar settings. It'll quickly drop the 768 down to around 550.

General Syntax:

7z a archive_name target parameters

Check your 7-Zip dir. Depending on the release you have, 7z may be replaced with 7za in the syntax.

Parameters:

• -p encrypt and prompt for PW.
• -pPUT_PASSWORD_HERE (this replaces -p) if you want to preset the PW with no prompt.
• -mhe=on to hide file structure, otherwise file structure and names will be visible by default.

Eg. This will prompt for a PW and hide file structures:

7z a archive_name target -p -mhe=on

Eg. No prompt, visible file structure:

7z a archive_name target -pPUT_PASSWORD_HERE

And so on. If you leave target blank, 7z will assume * in current directory and it will recurs directories by default.

Wanted to add my experience with converting. I had many text fields in ancient Linq2SQL code. This was to allow text columns present in indexes to be rebuilt ONLINE.

First I've known about the benefits for years, but always assumed that converting would mean some scary long queries where SQL Server would have to rebuild the table and copy everything over, bringing down my websites and raising my heartrate.

I was also concerned that the Linq2SQL could cause errors if it was doing some kind of verification of the column type.

Happy to report though, that the ALTER commands returned INSTANTLY - so they are definitely only changing table metadata. There may be some offline work happening to bring <8000 character data back to be in-table, but the ALTER command was instant.

I ran the following to find all columns needing conversion:

SELECT concat('ALTER TABLE dbo.[', table_name, '] ALTER COLUMN [', column_name, '] VARCHAR(MAX)'), table_name, column_name
FROM information_schema.columns where data_type = 'TEXT' order by table_name, column_name

SELECT concat('ALTER TABLE dbo.[', table_name, '] ALTER COLUMN [', column_name, '] NVARCHAR(MAX)'), table_name, column_name
FROM information_schema.columns where data_type = 'NTEXT' order by table_name, column_name

This gave me a nice list of queries, which I just selected and copied to a new window. Like I said - running this was instant.

Linq2SQL is pretty ancient - it uses a designer that you drag tables onto. The situation may be more complex for EF Code first but I haven't tackled that yet.

You only need to use LoadLibrary if you want to late bind and only resolve the imported functions at runtime. The easiest way to use a third party dll is to link against a .lib.

In reply to your edit:

Yes, the third party API should consist of a dll and/or a lib that contain the implementation and header files that declares the required types. You need to know the type definitions whichever method you use - for LoadLibrary you'll need to define function pointers, so you could just as easily write your own header file instead. Basically, you only need to use LoadLibrary if you want late binding. One valid reason for this would be if you aren't sure if the dll will be available on the target PC.

You can do the same in python by simply importing the second file, code at the top level will run when imported. I'd suggest this is messy at best, and not a good programming practice. You would be better off organizing your code into modules

Example:

F1.py:

print "Hello, "
import f2

F2.py:

print "World!"

When run:

python ./f1.py
Hello, 
World!

Edit to clarify: The part I was suggesting was "messy" is using the import statement only for the side effect of generating output, not the creation of separate source files.

This is helped for me.

For select:

$('select_tags').on('change', function() {
    alert( $(this).find(":selected").val() );
});

For radio/checkbox:

$('radio_tags').on('change', function() {
    alert( $(this).find(":checked").val() );
});

Implement the following operations of a queue using stacks.

push(x) -- Push element x to the back of queue.

pop() -- Removes the element from in front of queue.

peek() -- Get the front element.

empty() -- Return whether the queue is empty.

class MyQueue {

  Stack<Integer> input;
  Stack<Integer> output;

  /** Initialize your data structure here. */
  public MyQueue() {
    input = new Stack<Integer>();
    output = new Stack<Integer>();
  }

  /** Push element x to the back of queue. */
  public void push(int x) {
    input.push(x);
  }

  /** Removes the element from in front of queue and returns that element. */
  public int pop() {
    peek();
    return output.pop();
  }

  /** Get the front element. */
  public int peek() {
    if(output.isEmpty()) {
        while(!input.isEmpty()) {
            output.push(input.pop());
        }
    }
    return output.peek();
  }

  /** Returns whether the queue is empty. */
  public boolean empty() {
    return input.isEmpty() && output.isEmpty();
  }
}

You can use 'required' http://jsbin.com/atefuq/1/edit

<form action="login.php" method="post">
    <label>Login Name:</label>
    <input required type="text" name="email" id="log" />
    <label>Password:</label>
    <input required type="password" name="password" id="pwd" />
    <input  required type="submit" name="submit" value="Login" />
</form>

To find all files whose file status was last changed N minutes ago:

find -cmin -N

For example:

find -cmin -5

An alternative approach, which I've recently implemented, is to use the div-table plugin with panflute.

This creates a table from a set of fenced divs (standard in the pandoc implementation of markdown), in a similar layout to html:

---
panflute-filters: [div-table]
panflute-path: 'panflute/docs/source'
---

::::: {.divtable}
:::: {.tcaption}
a caption here (optional), only the first paragraph is used.
::::
:::: {.thead}
[Header 1]{width=0.4 align=center}
[Header 2]{width=0.6 align=default}
::::
:::: {.trow}
::: {.tcell}

1. any
2. normal markdown
3. can go in a cell

:::
::: {.tcell}
![](https://pixabay.com/get/e832b60e2cf7043ed1584d05fb0938c9bd22ffd41cb2144894f9c57aae/bird-1771435_1280.png?attachment){width=50%}

some text
:::
::::
:::: {.trow bypara=true}
If bypara=true

Then each paragraph will be treated as a separate column
::::
any text outside a div will be ignored
:::::

Looks like:

ORA-03113: end-of-file on communication channel

Is the database letting you know that the network connection is no more. This could be because:

1. A network issue - faulty connection, or firewall issue
2. The server process on the database that is servicing you died unexpectedly.

For 1) (firewall) search tahiti.oracle.com for SQLNET.EXPIRE_TIME. This is a sqlnet.ora parameter that will regularly send a network packet at a configurable interval ie: setting this will make the firewall believe that the connection is live.

For 1) (network) speak to your network admin (connection could be unreliable)

For 2) Check the alert.log for errors. If the server process failed there will be an error message. Also a trace file will have been written to enable support to identify the issue. The error message will reference the trace file.

Support issues can be raised at metalink.oracle.com with a suitable Customer Service Identifier (CSI)

Select * from a_table where attribute = 'k' COLLATE Latin1_General_CS_AS 

Did the trick.

a = a + b
b = a - b // b = a
a = a - b

This solution also removes values such as " ":

const result = ['', null, 'foo', '  ', undefined, 'bar'].filter(el => {
  return Boolean(el) && el.trim() !== '';
}).join(', ');

console.log(result); // => foo, bar

You only have one row to serialize. Try something like this :

List<results> resultRows = new List<results>

resultRows.Add(new results{id = 1, value="ABC", info="ABC"});
resultRows.Add(new results{id = 2, value="XYZ", info="XYZ"});

string json = JavaScriptSerializer.Serialize(new { results = resultRows});

• Edit to match OP's original json output

** Edit 2 : sorry, but I missed that he was using JSON.NET. Using the JavaScriptSerializer the above code produces this result :

{"results":[{"id":1,"value":"ABC","info":"ABC"},{"id":2,"value":"XYZ","info":"XYZ"}]}

If you are converting a timestamp value on a different machine, you should also check the timezone of that machine. For example;

The above decriptions will result different Date values, if you run with EST or UTC timezones.

To set the timezone; aka to UTC, you can simply rewrite;

    TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
    java.util.Date time= new java.util.Date((Long.parseLong(timestamp)*1000));

While the other answers are mostly fine, you could try another, more space-efficient, encoding method like yEnc. (yEnc wikipedia link) With yEnc also get checksum capability right "out of the box". Read and links below. Of course, because XML does not have a native yEnc type your XML schema should be updated to properly describe the encoded node.

Why: Due to the encoding strategies base64/63, uuencode et al. encodings increase the amount of data (overhead) you need to store and transfer by roughly 40% (vs. yEnc's 1-2%). Depending on what you're encoding, 40% overhead could be/become an issue.

yEnc - Wikipedia abstract: https://en.wikipedia.org/wiki/YEnc yEnc is a binary-to-text encoding scheme for transferring binary files in messages on Usenet or via e-mail. ... An additional advantage of yEnc over previous encoding methods, such as uuencode and Base64, is the inclusion of a CRC checksum to verify that the decoded file has been delivered intact. ?

The area element in a circle is dA=rdr*dphi. That extra factor r destroyed your idea to randomly choose a r and phi. While phi is distributed flat, r is not, but flat in 1/r (i.e. you are more likely to hit the boundary than "the bull's eye").

So to generate points evenly distributed over the circle pick phi from a flat distribution and r from a 1/r distribution.

Alternatively use the Monte Carlo method proposed by Mehrdad.

EDIT

To pick a random r flat in 1/r you could pick a random x from the interval [1/R, infinity] and calculate r=1/x. r is then distributed flat in 1/r.

To calculate a random phi pick a random x from the interval [0, 1] and calculate phi=2*pi*x.

Better is use datatype varchar(15).

Alarm Manager:

Add To XML Layout (*init these view on create in main activity)

  <TimePicker
    android:id="@+id/timepicker"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="2"></TimePicker>

  <Button
    android:id="@+id/btn_start"
    android:text="start Alarm"
    android:onClick="start_alarm_event"
    android:layout_width="match_parent"
    android:layout_height="52dp" />

Add To Manifest (Inside application tag && outside activity)

 <receiver android:name=".AlarmBroadcastManager"
        android:enabled="true"
        android:exported="true"/>

Create AlarmBroadcastManager Class(inherit it from BroadcastReceiver)

 public class AlarmBroadcastManager extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {
      MediaPlayer mediaPlayer=MediaPlayer.create(context,Settings.System.DEFAULT_RINGTONE_URI);
      mediaPlayer.start();
    }
 }

In Main Activity (Add these Functions):

 @RequiresApi(api = Build.VERSION_CODES.M)
 public  void start_alarm_event(View view){
    Calendar calendar=Calendar.getInstance();
    calendar.set(
    calendar.get(Calendar.YEAR),
    calendar.get(Calendar.MONTH),
    calendar.get(Calendar.DAY_OF_MONTH),
    timePicker.getHour(),
    timePicker.getMinute(),
    0
    );
    setAlarm(calendar.getTimeInMillis());
 }

 public void setAlarm(long timeInMillis){
    AlarmManager alarmManager=(AlarmManager) getSystemService(Context.ALARM_SERVICE);
    Intent intent=new Intent(this,AlarmBroadcastManager.class);
    PendingIntent pendingIntent=PendingIntent.getBroadcast(this,0,intent,0);
     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,timeInMillis,AlarmManager.INTERVAL_DAY,pendingIntent);
    Toast.makeText(getApplicationContext(),"Alarm is Set",Toast.LENGTH_SHORT).show();


 }

I had to run an application as root (to open a webserver on port 80), this produced the error for me, because the sudo user has a different environment than the normal user, hence GOPATH was not set.

If someone else is having this problem, add -E to the command, this will preserve the user environment.

sudo -E go run main.go

For more infos see discussion here: Google Groups – GOPATH Problem

Here's a jQuery solution.

<script type="text/javascript" src="/path/to/your/copy/of/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
    $("#sub1").mouseover(function() {
        $("#welcome").toggle();
    });
});
</script>

Using this markup:

<div id="sub1">some text</div>
<div id="welcome" style="display:none;">Welcome message</div>

You didn't really specify if (or when) you wanted to hide the welcome message, but this would toggle hiding or showing each time you moused over the text.

JSX isn't standard JavaScript, based to Airbnb style guide 'eslint' could consider this pattern

// filename: MyComponent.js
function MyComponent() {
  return <div />;
}

as a warning, if you named your file MyComponent.jsx it will pass , unless if you edit the eslint rule you can check the style guide here

gzip -dc archive.tar.gz | tar -xf - -C /destination

Here's how do to it with the SSDB catalog that was introduced with SQL Server 2012...

using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Data.SqlClient;

using Microsoft.SqlServer.Management.IntegrationServices;

public List<string> ExecutePackage(string folder, string project, string package)
{
    // Connection to the database server where the packages are located
    SqlConnection ssisConnection = new SqlConnection(@"Data Source=.\SQL2012;Initial Catalog=master;Integrated Security=SSPI;");

    // SSIS server object with connection
    IntegrationServices ssisServer = new IntegrationServices(ssisConnection);

    // The reference to the package which you want to execute
    PackageInfo ssisPackage = ssisServer.Catalogs["SSISDB"].Folders[folder].Projects[project].Packages[package];

    // Add a parameter collection for 'system' parameters (ObjectType = 50), package parameters (ObjectType = 30) and project parameters (ObjectType = 20)
    Collection<PackageInfo.ExecutionValueParameterSet> executionParameter = new Collection<PackageInfo.ExecutionValueParameterSet>();

    // Add execution parameter (value) to override the default asynchronized execution. If you leave this out the package is executed asynchronized
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 50, ParameterName = "SYNCHRONIZED", ParameterValue = 1 });

    // Add execution parameter (value) to override the default logging level (0=None, 1=Basic, 2=Performance, 3=Verbose)
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 50, ParameterName = "LOGGING_LEVEL", ParameterValue = 3 });

    // Add a project parameter (value) to fill a project parameter
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 20, ParameterName = "MyProjectParameter", ParameterValue = "some value" });

    // Add a project package (value) to fill a package parameter
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 30, ParameterName = "MyPackageParameter", ParameterValue = "some value" });

    // Get the identifier of the execution to get the log
    long executionIdentifier = ssisPackage.Execute(false, null, executionParameter);

    // Loop through the log and do something with it like adding to a list
    var messages = new List<string>();
    foreach (OperationMessage message in ssisServer.Catalogs["SSISDB"].Executions[executionIdentifier].Messages)
    {
        messages.Add(message.MessageType + ": " + message.Message);
    }

    return messages;
}

I have created a small utility function, this works well for me

def display_text_max_col_width(df, width):
    with pd.option_context('display.max_colwidth', width):
        print(df)

display_text_max_col_width(train_df["Description"], 800)

I can change length of the width as per my requirement, without setting any option permanently.

I love this piece of code, use it to load a file into one String:

File file = new File("/my/location");
String contents = new Scanner(file).useDelimiter("\\Z").next();

I unable to comment on the top answer, but Excel actually lets you do this without adding the ugly conditional logic.

Conditional formatting is automatically applied to any input that isn't an error, so you can achieve the same effect as:

=NOT(ISERROR(MATCH(A1,$B$1:$B$1000,0)))

With this:

= MATCH(A1,$B$1:$B$1000,0)))

If the above is applied to your data, A1 will be formatted if it matches any cell in $B$1:$B$1000, as any non-match will return an error.

Using Following Code You Solve thisQuestion.... If you run a file using localhost server than this problem solve by following Jsp Page Code.This Code put Between Head Tag in jsp file

</style>
<script type="text/javascript">
    <%@include file="js/script.js" %>

In distributable software, I dont want my customers mucking about in the database by themselves. The program reads and writes it all by itself. The only reason for a user to touch the DB file is to take a backup copy. Therefore I have named it whatever_records.db

The simple .db extension tells the user that it is a binary data file and that's all they have to know. Calling it .sqlite invites the interested user to open it up and mess something up!

Totally depends on your usage scenario I suppose.

I haven't used it yet but I would take a look at http://www.zoneminder.com/ The documentation explains you can install it on a modest machine with linux and use IP cameras for remote recording.

In older versions of jquery you'll have to do it the "javascript way" using settimeout

setTimeout( function(){$('div').hide();} , 4000);

or

setTimeout( "$('div').hide();", 4000);

Recently with jquery 1.4 this solution has been added:

$("div").delay(4000).hide();

Of course replace "div" by the correct element using a valid jquery selector and call the function when the document is ready.

I've created go project for string formatting from template (it allow to format strings in C# or Python style, just first version for very simple cases), you could find it here https://github.com/Wissance/stringFormatter

it works in following manner:

func TestStrFormat(t *testing.T) {
    strFormatResult, err := Format("Hello i am {0}, my age is {1} and i am waiting for {2}, because i am {0}!",
                              "Michael Ushakov (Evillord666)", "34", "\"Great Success\"")
    assert.Nil(t, err)
    assert.Equal(t, "Hello i am Michael Ushakov (Evillord666), my age is 34 and i am waiting for \"Great Success\", because i am Michael Ushakov (Evillord666)!", strFormatResult)

    strFormatResult, err = Format("We are wondering if these values would be replaced : {5}, {4}, {0}", "one", "two", "three")
    assert.Nil(t, err)
    assert.Equal(t, "We are wondering if these values would be replaced : {5}, {4}, one", strFormatResult)

    strFormatResult, err = Format("No args ... : {0}, {1}, {2}")
    assert.Nil(t, err)
    assert.Equal(t, "No args ... : {0}, {1}, {2}", strFormatResult)

There is no precise meaning, precisely because these terms mean the opposite things depending on whether you are merging or rebasing. THE natural way of thinking about two branches is "my work" and "someone else's work". The choice of terminology that obscures this classification is absolutely THE worst design choice in git. It must have been inspired by accounting's "credit" and "debit" or "assets" and "liabilities" - same headache.

Similar to C# casting to (int) with just using standard lib:

Math.trunc(1.6) // 1
Math.trunc(-1.6) // -1

{Imagine two objects: A and B of same type _t(with respect to C++) and you are thinking about shallow/deep copying A to B}

Shallow Copy: Simply makes a copy of the reference to A into B. Think about it as a copy of A's Address. So, the addresses of A and B will be the same i.e. they will be pointing to the same memory location i.e. data contents.

Deep copy: Simply makes a copy of all the members of A, allocates memory in a different location for B and then assigns the copied members to B to achieve deep copy. In this way, if A becomes non-existant B is still valid in the memory. The correct term to use would be cloning, where you know that they both are totally the same, but yet different (i.e. stored as two different entities in the memory space). You can also provide your clone wrapper where you can decide via inclusion/exclusion list which properties to select during deep copy. This is quite a common practice when you create APIs.

You can choose to do a Shallow Copy ONLY_IF you understand the stakes involved. When you have enormous number of pointers to deal with in C++ or C, doing a shallow copy of an object is REALLY a bad idea.

EXAMPLE_OF_DEEP COPY_ An example is, when you are trying to do image processing and object recognition you need to mask "Irrelevant and Repetitive Motion" out of your processing areas. If you are using image pointers, then you might have the specification to save those mask images. NOW... if you do a shallow copy of the image, when the pointer references are KILLED from the stack, you lost the reference and its copy i.e. there will be a runtime error of access violation at some point. In this case, what you need is a deep copy of your image by CLONING it. In this way you can retrieve the masks in case you need them in the future.

EXAMPLE_OF_SHALLOW_COPY I am not extremely knowledgeable compared to the users in StackOverflow so feel free to delete this part and put a good example if you can clarify. But I really think it is not a good idea to do shallow copy if you know that your program is gonna run for an infinite period of time i.e. continuous "push-pop" operation over the stack with function calls. If you are demonstrating something to an amateur or novice person (e.g. C/C++ tutorial stuff) then it is probably okay. But if you are running an application such as surveillance and detection system, or Sonar Tracking System, you are not supposed to keep shallow copying your objects around because it will kill your program sooner or later.

some people have suggested the "visited", but the visited links remain in the browsers cache, so the next time your user visits the page, the link will have the second image.. i dont know it that's the desired effect you want. Anyway you coul mix JS and CSS:

<style>
.off{
    color:red;
}
.on{
    color:green;
}
</style>
<a href="" class="off" onclick="this.className='on';return false;">Foo</a>

using the onclick event, you can change (or toggle maybe?) the class name of the element. In this example i change the text color but you could also change the background image.

Good Luck

As for ERRORCODE 39, you can definately just delete the physical table files on the disk. the location depends on your OS distribution and setup. On Debian its typically under /var/lib/mysql/database_name/ So do a:

rm -f /var/lib/mysql/<database_name>/

And then drop the database from your tool of choice or using the command:

DROP DATABASE <database_name>

Method One (Small Sites Only):
Serve encrypted / encoded data.
I Scape the web using python (urllib, requests, beautifulSoup etc...) and found many websites that serve encrypted / encoded data that is not decrypt-able in any programming language simply because the encryption method does not exist.

I achieved this in a PHP website by encrypting and minimizing the output (WARNING: this is not a good idea for large sites) the response was always jumbled content.

Example of minimizing output in PHP (How to minify php page html output?):

<?php
  function sanitize_output($buffer) {
    $search = array(
      '/\>[^\S ]+/s', // strip whitespaces after tags, except space
      '/[^\S ]+\</s', // strip whitespaces before tags, except space
      '/(\s)+/s'      // shorten multiple whitespace sequences
    );
    $replace = array('>', '<', '\\1');
    $buffer = preg_replace($search, $replace, $buffer);
    return $buffer;
  }
  ob_start("sanitize_output");
?>

Method Two:
If you can't stop them screw them over serve fake / useless data as a response.

Method Three:
block common scraping user agents, you'll see this in major / large websites as it is impossible to scrape them with "python3.4" as you User-Agent.

Method Four:
Make sure all the user headers are valid, I sometimes provide as many headers as possible to make my scraper seem like an authentic user, some of them are not even true or valid like en-FU :).
Here is a list of some of the headers I commonly provide.

headers = {
  "Requested-URI": "/example",
  "Request-Method": "GET",
  "Remote-IP-Address": "656.787.909.121",
  "Remote-IP-Port": "69696",

Tip #1

Never use Write-Host.

Tip #12

The correct way to output information from a PowerShell cmdlet or function is to create an object that contains your data, and then to write that object to the pipeline by using Write-Output.

-Don Jones: PowerShell Master

Ideally your script would create your objects ($obj = New-Object -TypeName psobject -Property @{'SomeProperty'='Test'}) then just do a Write-Output $objects. You would pipe the output to Format-Table.

PS C:\> Run-MyScript.ps1 | Format-Table

They should really call PowerShell PowerObjectandPipingShell.

I had this same problem and made my own library for it that uses ctypes:

"""

There is a way to do it using reflection. It works with .NET 4.0. It accesses a private field and may not work in other versions of .NET without modifications.

I have no idea why Microsoft did not expose this field with a property.

private static int GetStatusCode(WebClient client, out string statusDescription)
{
    FieldInfo responseField = client.GetType().GetField("m_WebResponse", BindingFlags.Instance | BindingFlags.NonPublic);

    if (responseField != null)
    {
        HttpWebResponse response = responseField.GetValue(client) as HttpWebResponse;

        if (response != null)
        {
            statusDescription = response.StatusDescription;
            return (int)response.StatusCode;
        }
    }

    statusDescription = null;
    return 0;
}

You may be interested in the csv module, which is designed for comma-separated files but can be easily modified to use a custom delimiter.

One approach not yet given is to use a parser generator to create a parser in XSLT which parses JSON and produces an XML output.

One option that gets mentioned a lot at the XML conferences is the ReX parser generator (http://www.bottlecaps.de/rex/) - although totally undocumented on the site, recipes are available on searching.

In addition to given answer, it's worth noting that compiler is not required to initialize constexpr variable at compile time, knowing that the difference between constexpr and static constexpr is that to use static constexpr you ensure the variable is initialized only once.

Following code demonstrates how constexpr variable is initialized multiple times (with same value though), while static constexpr is surely initialized only once.

In addition the code compares the advantage of constexpr against const in combination with static.

#include <iostream>
#include <string>
#include <cassert>
#include <sstream>

const short const_short = 0;
constexpr short constexpr_short = 0;

// print only last 3 address value numbers
const short addr_offset = 3;

// This function will print name, value and address for given parameter
void print_properties(std::string ref_name, const short* param, short offset)
{
    // determine initial size of strings
    std::string title = "value \\ address of ";
    const size_t ref_size = ref_name.size();
    const size_t title_size = title.size();
    assert(title_size > ref_size);

    // create title (resize)
    title.append(ref_name);
    title.append(" is ");
    title.append(title_size - ref_size, ' ');

    // extract last 'offset' values from address
    std::stringstream addr;
    addr << param;
    const std::string addr_str = addr.str();
    const size_t addr_size = addr_str.size();
    assert(addr_size - offset > 0);

    // print title / ref value / address at offset
    std::cout << title << *param << " " << addr_str.substr(addr_size - offset) << std::endl;
}

// here we test initialization of const variable (runtime)
void const_value(const short counter)
{
    static short temp = const_short;
    const short const_var = ++temp;
    print_properties("const", &const_var, addr_offset);

    if (counter)
        const_value(counter - 1);
}

// here we test initialization of static variable (runtime)
void static_value(const short counter)
{

Possible program output:

value \ address of static is              1 C58

value \ address of static const is        1 C64
value \ address of static const is        1 C64
value \ address of static const is        1 C64

value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0

As you can see yourself constexpr is initilized multiple times (address is not the same) while static keyword ensures that initialization is performed only once.

The following is a great in depth reference by Dare Obasanjo on the differences between C# and Java. I always find myself referring to this article when switching between the two.

http://www.25hoursaday.com/CsharpVsJava.html

According to this post this error message means:

Heap size is larger than your computer's physical memory.

Edit: Heap is not the only memory that is reserved, I suppose. At least there are other JVM settings like PermGenSpace that ask for the memory. With heap size 128M and a PermGenSpace of 64M you already fill the space available.

Why not downsize other memory settings to free up space for the heap?

I think Gumbo's answer is just fine. Some people prefer this fancy expression that does the same thing:

$int = (($int > 0) ? -$int : $int);

EDIT: Apparently you are looking for a function that will make negatives positive as well. I think these answers are the simplest:

/* I am not proposing you actually use functions called
   "makeNegative" and "makePositive"; I am just presenting
   the most direct solution in the form of two clearly named
   functions. */
function makeNegative($num) { return -abs($num); }
function makePositive($num) { return abs($num); }

It is possible to apply the specific GridView / Table layout via custom CSS rules (as it was discussed in the <table><tbody> scrollable? thread) to fix GridView's Header. However, this approach will not work in all browsers. The 3-rd ASP.NET GridView controls (such as the ASPxGridView from DevExpress component vendor provide this functionality.

Check also the following CodeProject solutions:

• Fixed header Grid

• Gridview with fixed header

• Gridview Fixed Header

Here I want to pad my number with 4 digit. For instance, if it is 1 then it should show as 0001, if it 11 it should show as 0011.

Below is the code that accomplishes this:

reciptno=1; // Pass only integer.

string formatted = string.Format("{0:0000}", reciptno);

TxtRecNo.Text = formatted; // Output=0001

I implemented this code to generate money receipt number for a PDF file.

To enable intl extension follow the instructions below.

You need enable extension by uncommenting the following line extension=php_intl.dll in the C:\xampp\php\php.ini file. Once you uncomment the extension=php_intl.dll, then you must restart apache server using XAMPP control panel.

//about line 998
;extension=php_intl.dll 
change as
extension=php_intl.dll

(Note: php.ini file mostly in the following directory C:\xampp\php)

Restart xampp

Simply use

var xmlString = '<?xml version="1.0" ?><root />';
var xml = jQuery.parseXML(xml);

It's jQuery.parseXML, so no need to worry about cross-browser tricks. Use jQuery as like HTML, it's using the native XML engine.

This same problem occurs when the owners of the file have been deleted. When this happens, if you go to the file's properties, you will see a SID rather than a user name. Take ownership of the file (giving yourself FULL CONTROL). Once that is done you can do whatever you need to do with the file.

I've had this work when logging in as the administrator didn't do the trick.

I like to do this witch i think is cleaner :

1 - Add the model to namespace:

use App\Employee;

2 - then you can do :

$employees = Employee::get();

or maybe somthing like this:

$employee = Employee::where('name', 'John')->first();

I think you should be able to follow the method used in this post. It looks really ugly, but I would think you could do it twice and get the result you want.

I wonder if this is actually a case where you'd be better off using DataContext.ExecuteCommand(...) instead of converting to linq.

while (num != 0) {
    rev = rev * 10 + num % 10;
    num /= 10;
}

That is the solution I used for this problem, and it works fine. More details:

num % 10

This statement will get you the last digit from the original number.

num /= 10

This statement will eliminate the last digit from the original number, and hence we are sure that while loop will terminate.

rev = rev * 10 + num % 10

Here rev*10 will shift the value by left and then add the last digit from the original.
If the original number was 1258, and in the middle of the run time we have rev = 85, num = 12 so:
num%10 = 2
rev*10 = 850
rev*10 + num%10 = 852

Since there were no exact answers to my question, I made some investigation why my code doesn't work when there are other solutions that works, and decided to post what I found to complete the subject.
As it turns out:

"ssh uses direct TTY access to make sure that the password is indeed issued by an interactive keyboard user." sshpass manpage

which answers the question, why the pipes don't work in this case. The obvious solution was to create conditions so that ssh "thought" that it is run in the regular terminal and since it may be accomplished by simple posix functions, it is beyond what simple bash offers.

In HTML:

<form onsubmit="return false">
</form>

in order to avoid refresh at all "buttons", even with onclick assigned.

The reason that the error is occuring is because all the files are not being recognized as being in the same project directory. The easiest way to fix this is to simply create a new project.

File -> Project -> Console application -> Next -> select C or C++ -> Name the project and select the folder to create the project in -> then click finish.

Then to create the class and header files by clicking New -> Class. Give the class a name and uncheck "Use relative path." Make sure you are creating the class and header file in the same project folder.

After these steps, the left side of the IDE will display the Sources and Headers folders, with main.cpp, theclassname.cpp, and theclassname.h all conviently arranged.

Some browsers igoners sending leading zero to the server when the input type is "number". So I use a mixing of jquery and html to load a numeric keypad and also make sure that the value is sent as a text not as a number:

$(document).ready(function(){_x000D_
$(".numberonly").focus(function(){$(this).attr("type","number")});_x000D_
$(".numberonly").blur(function(){$(this).attr("type","text")});_x000D_
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="text" class="numberonly">

I faced the same problem. I hope you have installed from here and have also done pip install pytesseract.

If everything is fine you should see that the path C:\Program Files (x86)\Tesseract-OCR where tesseract.exe is available.

Adding Path variable did not helped me, I actually added new variable with name tesseract in environment variables with a value of C:\Program Files (x86)\Tesseract-OCR\tesseract.exe.

Typing tesseract in the command line should now work as expected by giving you usage informations. You can now use pytesseract as such (don't forget to restart your python kernel before running this!):

import pytesseract
from PIL import Image

value=Image.open("text_image.png")
text = pytesseract.image_to_string(value, config='')    
print("text present in images:",text)

enjoy!

Efficiency isn't going to matter for something like this in 99.999999% of situations. Do whatever is easier to read and or maintain.

In my apps I usually rely on classes to provide hiding and showing, for example .addClass('isHidden')/.removeClass('isHidden') which would allow me to animate things with CSS3 if I wanted to. It provides more flexibility.

Paste this next to your values(bytes) and this will automatically change it to whatever your size of value is.

=IF(G10>=1099511627776,CONCATENATE(ROUND((G10/1024/1024/1024/1024),1)," TB"),IF(G10>=1073741824,CONCATENATE(ROUND((G10/1024/1024/1024),1)," GB"),IF(G10>=1048576,CONCATENATE(ROUND((G10/1024/1024),1)," MB"),IF(G10>=1024,CONCATENATE(ROUND((G10/1024),1)," KB"),IF(G10>=1,CONCATENATE((G10)," BYTES"),0)))))

Try eUML2. its a single click generator no need to drag n drop.

Since atleast Java 1.5.0 (Java 5) the code can be cleaned up a bit. Arrays and anything that implements Iterator (e.g. Collections) can be looped as such:

public static boolean inArray(int[] array, int check) {
   for (int o : array){
      if (o == check) {
         return true;
      }
   }
   return false;
}

In Java 8 you can also do something like:

// import java.util.stream.IntStream;

public static boolean inArray(int[] array, int check) {
   return IntStream.of(array).anyMatch(val -> val == check);
}

Although converting to a stream for this is probably overkill.

If you already know size of the char*, use this instead

char* data = ...;
int size = ...;
std::string myString(data, size);

This doesn't use strlen.

EDIT: If string variable already exists, use assign():

std::string myString;
char* data = ...;
int size = ...;
myString.assign(data, size);

There are several possible methods, but for you, there is already a builtin parse_str function

$array = array();
parse_str($string, $array);
var_dump($array);

If you have a number, for example 65, and if you want to get the corresponding ASCII character, you can use the chr function, like this

>>> chr(65)
'A'

similarly if you have 97,

>>> chr(97)
'a'

EDIT: The above solution works for 8 bit characters or ASCII characters. If you are dealing with unicode characters, you have to specify unicode value of the starting character of the alphabet to ord and the result has to be converted using unichr instead of chr.

>>> print unichr(ord(u'\u0B85'))
?

>>> print unichr(1 + ord(u'\u0B85'))
?

NOTE: The unicode characters used here are of the language called "Tamil", my first language. This is the unicode table for the same http://www.unicode.org/charts/PDF/U0B80.pdf

days, years, etc., are part of Active Support, So this won't work in irb, but it should work in rails console.

This is normal if you see it. Since it is the first virtual host entry, it will show local host.

Let’s say for example you didn't want that page to show. All you want to show is the "Apache, it works" page, so you would make a vhost entry before mysite.local as local host and point it to the "it works" page.

But this is normal. I had this problem before, so don't worry!

The best HTTP header for your client to send an access token (JWT or any other token) is the Authorization header with the Bearer authentication scheme.

This scheme is described by the RFC6750.

Example:

GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer eyJhbGciOiJIUzI1NiIXVCJ9TJV...r7E20RMHrHDcEfxjoYZgeFONFh7HgQ

If you need stronger security protection, you may also consider the following IETF draft: https://tools.ietf.org/html/draft-ietf-oauth-pop-architecture. This draft seems to be a good alternative to the (abandoned?) https://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac.

Note that even if this RFC and the above specifications are related to the OAuth2 Framework protocol, they can be used in any other contexts that require a token exchange between a client and a server.

Unlike the custom JWT scheme you mention in your question, the Bearer one is registered at the IANA.

Concerning the Basic and Digest authentication schemes, they are dedicated to authentication using a username and a secret (see RFC7616 and RFC7617) so not applicable in that context.

Acoording to RFC 2046 (Multipurpose Internet Mail Extensions):

The recommended action for an implementation that receives an
"application/octet-stream" entity is to simply offer to put the data in a file

So I'd go for that one.

You may want to look into os dependent line separators, e.g.:

import os

with open('./output.txt', 'a') as f1:
    f1.write(content + os.linesep)

There are many ways to do it:
One way:

#mybox:hover {
   display:none;
}

Another way:

#mybox:hover {
   visibility: hidden;
}

Or you could just do:

#mybox:hover {
   background:transparent;
   color:transparent;
}

try

location = url;

function url() {_x000D_
    location = 'https://example.com';_x000D_
}

<input type="button" value="Inline" _x000D_
onclick="location='https://example.com'" />_x000D_
_x000D_
<input type="button" value="URL()" _x000D_
onclick="url()" />

I'd suggest to use .nth(0) rather than .first() if you need to get the first row.

The difference between them is how they handle NaNs, so .nth(0) will return the first row of group no matter what are the values in this row, while .first() will eventually return the first not NaN value in each column.

E.g. if your dataset is :

df = pd.DataFrame({'id' : [1,1,1,2,2,3,3,3,3,4,4],
            'value'  : ["first","second","third", np.NaN,
                        "second","first","second","third",
                        "fourth","first","second"]})

>>> df.groupby('id').nth(0)
    value
id        
1    first
2    NaN
3    first
4    first

And

>>> df.groupby('id').first()
    value
id        
1    first
2    second
3    first
4    first

You might have done something like this:

>>> tuple = 45, 34  # You used `tuple` as a variable here
>>> tuple
(45, 34)
>>> l = [4, 5, 6]
>>> tuple(l)   # Will try to invoke the variable `tuple` rather than tuple type.

Traceback (most recent call last):
  File "<pyshell#10>", line 1, in <module>
    tuple(l)
TypeError: 'tuple' object is not callable
>>>
>>> del tuple  # You can delete the object tuple created earlier to make it work
>>> tuple(l)
(4, 5, 6)

Here's the problem... Since you have used a tuple variable to hold a tuple (45, 34) earlier... So, now tuple is an object of type tuple now...

It is no more a type and hence, it is no more Callable.

Never use any built-in types as your variable name... You do have any other name to use. Use any arbitrary name for your variable instead...

Seaborn box plot returns a matplotlib axes instance. Unlike pyplot itself, which has a method plt.title(), the corresponding argument for an axes is ax.set_title(). Therefore you need to call

sns.boxplot('Day', 'Count', data= gg).set_title('lalala')

A complete example would be:

import seaborn as sns
import matplotlib.pyplot as plt

tips = sns.load_dataset("tips")
sns.boxplot(x=tips["total_bill"]).set_title("LaLaLa")

plt.show()

Of course you could also use the returned axes instance to make it more readable:

ax = sns.boxplot('Day', 'Count', data= gg)
ax.set_title('lalala')
ax.set_ylabel('lololo')

Accessing the files directly on your phone is difficult, but you may be able to copy them to your computer where you can do anything you want with it. Without rooting you have 2 options:

1. If the application is debuggable you can use the run-as command in adb shell

   adb shell
   run-as com.your.packagename 
   cp /data/data/com.your.packagename/
   

2. Alternatively you can use Android's backup function.

   adb backup -noapk com.your.packagename
   

   You will now be prompted to 'unlock your device and confirm the backup operation'. It's best NOT to provide a password, otherwise it becomes more difficult to read the data. Just click on 'backup my data'. The resulting 'backup.ab' file on your computer contains all application data in android backup format. Basically it's a compressed tar file. This page explains how you can use OpenSSL's zlib command to uncompress it. You can use the adb restore backup.db command to restore the backup.

Html.Hidden and Html.HiddenFor used to generate name-value pairs which waited by action method in controller. Sample Usage(*):

@using (Html.BeginForm("RemoveFromCart", "Cart")) {
                    @Html.Hidden("ProductId", line.Product.ProductID)
                    @Html.HiddenFor(x => x.ReturnUrl)
                    <input class="btn btn-sm btn-warning"
                           type="submit" value="Remove" />
                }

If your action method wait for "ProductId" you have to generate this name in form via using (Html.Hidden or Html.HiddenFor) For the case it is not possible to generate this name with strongly typed model you simple write this name with a string thats "ProductId".

public ViewResult RemoveFromCart(int productId, string returnUrl){...}

If I had written Html.HiddenFor(x => line.Product.ProductID), the helper would render a hidden field with the name "line.Product.ProductID". The name of the field would not match the names of the parameters for the "RemoveFromCart" action method which waiting the name of "ProductId". This would prevent the default model binders from working, so the MVC Framework would not be able to call the method.

I've built up on @user1032613's answer and on this answer and created a "on press enter click element with querystring" hook. enjoy!

const { useEffect } = require("react");

const useEnterKeyListener = ({ querySelectorToExecuteClick }) => {
    useEffect(() => {
        //https://stackoverflow.com/a/59147255/828184
        const listener = (event) => {
            if (event.code === "Enter" || event.code === "NumpadEnter") {
                handlePressEnter();
            }
        };

        document.addEventListener("keydown", listener);

        return () => {
            document.removeEventListener("keydown", listener);
        };
    }, []);

    const handlePressEnter = () => {
        //https://stackoverflow.com/a/54316368/828184
        const mouseClickEvents = ["mousedown", "click", "mouseup"];
        function simulateMouseClick(element) {
            mouseClickEvents.forEach((mouseEventType) =>
                element.dispatchEvent(
                    new MouseEvent(mouseEventType, {
                        view: window,
                        bubbles: true,
                        cancelable: true,
                        buttons: 1,
                    })
                )
            );
        }

        var element = document.querySelector(querySelectorToExecuteClick);
        simulateMouseClick(element);
    };
};

export default useEnterKeyListener;

This is how you use it:

useEnterKeyListener({
    querySelectorToExecuteClick: "#submitButton",
});

As a contemporary alternative, there is a standard now for client side cryptography. This has the advantage of being optimised by the browser itself.

Taken from the example in the documentation:

async function sha256(message) {

    // encode as UTF-8
    const msgBuffer = new TextEncoder('utf-8').encode(message);

    // hash the message
    const hashBuffer = await crypto.subtle.digest('SHA-256', msgBuffer);

    // convert ArrayBuffer to Array
    const hashArray = Array.from(new Uint8Array(hashBuffer));

    // convert bytes to hex string
    const hashHex = hashArray.map(b => ('00' + b.toString(16)).slice(-2)).join('');
    return hashHex;
}

sha256('abc').then(hash => console.log(hash));

(async function() {
    const hash = await sha256('abc');
}());

MD5 is likely unsupported, however the likes of SHA-256, SHA-384, and SHA-512 are.

And those will likely be able to be calculated server side also.

Here's some documentation on usage: https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/digest

Difference between install, update and require

Assume the following scenario:

composer.json

"parsecsv/php-parsecsv": "0.*"

composer.lock file

  "name": "parsecsv/php-parsecsv",
            "version": "0.1.4",

Latest release is 1.1.0. The latest 0.* release is 0.3.2

install: composer install parsecsv/php-parsecsv

This will install version 0.1.4 as specified in the lock file

update: composer update parsecsv/php-parsecsv

This will update the package to 0.3.2. The highest version with respect to your composer.json. The entry in composer.lock will be updated.

require: composer require parsecsv/php-parsecsv

This will update or install the newest version 1.1.0. Your composer.lock file and composer.json file will be updated as well.

and of course the following:

var count = $("#myList").children().length;

can be condensed down to: (by removing the 'var' which is not necessary to set a variable)

count = $("#myList").children().length;

however this is cleaner:

count = $("#mylist li").size();

An easy way to login with a HTTP POST without doing any Base64 specific calls is to use the HTTPClient BasicCredentialsProvider

import java.io.IOException;
import static java.lang.System.out;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.client.HttpClientBuilder;

//code
CredentialsProvider provider = new BasicCredentialsProvider();
UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(user, password);
provider.setCredentials(AuthScope.ANY, credentials);
HttpClient client = HttpClientBuilder.create().setDefaultCredentialsProvider(provider).build();

HttpResponse response = client.execute(new HttpPost("http://address/test/login"));//Replace HttpPost with HttpGet if you need to perform a GET to login
int statusCode = response.getStatusLine().getStatusCode();
out.println("Response Code :"+ statusCode);

Pass updlock, rowlock, holdlock hints when testing for existence of the row.

begin tran /* default read committed isolation level is fine */

if not exists (select * from Table with (updlock, rowlock, holdlock) where ...)
    /* insert */
else
    /* update */

commit /* locks are released here */

The updlock hint forces the query to take an update lock on the row if it already exists, preventing other transactions from modifying it until you commit or roll back.

The holdlock hint forces the query to take a range lock, preventing other transactions from adding a row matching your filter criteria until you commit or roll back.

The rowlock hint forces lock granularity to row level instead of the default page level, so your transaction won't block other transactions trying to update unrelated rows in the same page (but be aware of the trade-off between reduced contention and the increase in locking overhead - you should avoid taking large numbers of row-level locks in a single transaction).

See http://msdn.microsoft.com/en-us/library/ms187373.aspx for more information.

Note that locks are taken as the statements which take them are executed - invoking begin tran doesn't give you immunity against another transaction pinching locks on something before you get to it. You should try and factor your SQL to hold locks for the shortest possible time by committing the transaction as soon as possible (acquire late, release early).

Note that row-level locks may be less effective if your PK is a bigint, as the internal hashing on SQL Server is degenerate for 64-bit values (different key values may hash to the same lock id).

This has been driving me crazy for literally weeks. I found a solution that will work for me that includes:

1. Non-fixed column widths - they shrink and grow on window resizing.
2. Table has a horizontal scroll-bar when needed, but not when it isn't.
3. Number of columns is irrelevant - it will size to however many columns you need it to.
4. Not all columns need to be the same width.
5. Header goes all the way to the end of the right scrollbar.
6. No javascript!

...but there are a couple of caveats:

1. The vertical scrollbar is not visible until you scroll all the way to the right. Given that most people have scroll wheels, this was an acceptable sacrifice.

2. The width of the scrollbar must be known. On my website I set the scrollbar widths (I'm not overly concerned with older, incompatible browsers), so I can then calculate div and table widths that adjust based on the scrollbar.

Instead of posting my code here, I'll post a link to the jsFiddle.

Fixed header table + scroll left/right.

process.terminate() doesn't work when using shell=True. This answer will help you.

First you have to check login existence using syslogins view:

IF NOT EXISTS 
    (SELECT name  
     FROM master.sys.server_principals
     WHERE name = 'YourLoginName')
BEGIN
    CREATE LOGIN [YourLoginName] WITH PASSWORD = N'password'
END

Then you have to check your database existence:

USE your_dbname

IF NOT EXISTS
    (SELECT name
     FROM sys.database_principals
     WHERE name = 'your_dbname')
BEGIN
    CREATE USER [your_dbname] FOR LOGIN [YourLoginName] 
END

is very simple

1. su - postgres
2. psql
3. REASSIGN OWNED BY [old_user] TO [new_user];
4. \c [your database]
5. REASSIGN OWNED BY [old_user] TO [new_user];

done.

There's a more convenient way to store passwords in a script but you will have to encrypt and obfuscate the script so that it cannot be read. In order to successfully encrypt and obfuscate a shell script and actually have that script be executable, try copying and pasting it here:

http://www.kinglazy.com/shell-script-encryption-kinglazy-shieldx.htm

On the above page, all you have to do is submit your script and give the script a proper name, then hit the download button. A zip file will be generated for you. Right click on the download link and copy the URL you're provided. Then, go to your UNIX box and perform the following steps.

Installation:

1. wget link-to-the-zip-file
2. unzip the-newly-downloaded-zip-file
3. cd /tmp/KingLazySHIELD
4. ./install.sh /var/tmp/KINGLAZY/SHIELDX-(your-script-name) /home/(your-username) -force

What the above install command will do for you is:

1. Install the encrypted version of your script in the directory /var/tmp/KINGLAZY/SHIELDX-(your-script-name).
2. It'll place a link to this encrypted script in whichever directory you specify in replacement of /home/(your-username) - that way, it allows you to easily access the script without having to type the absolute path.
3. Ensures NO ONE can modify the script - Any attempts to modify the encrypted script will render it inoperable...until those attempts are stopped or removed. It can even be configured to notify you whenever someone tries to do anything with the script other than run it...i.e. hacking or modification attempts.
4. Ensures absolutely NO ONE can make copies of it. No one can copy your script to a secluded location and try to screw around with it to see how it works. All copies of the script must be links to the original location which you specified during install (step 4).

NOTE:

This does not work for interactive scripts that prompts and waits on the user for a response. The values that are expected from the user should be hard-coded into the script. The encryption ensures no one can actually see those values so you need not worry about that.

RELATION:

The solution provided in this post answers your problem in the sense that it encrypts the actual script containing the password that you wanted to have encrypted. You get to leave the password as is (unencrypted) but the script that the password is in is so deeply obfuscated and encrypted that you can rest assured no one will be able to see it. And if attempts are made to try to pry into the script, you will receive email notifications about them.

// The integer I want to convert

int myInt = 100;

// Casting of integer to float

float newFloat = (float) myInt

int count = 0;
foreach (ListViewItem lvi in listView.Items)
{
    if(++count > 50) break;
}

Try this jquery plugin. Although, this is not a pure HTML and CSS solution, but it is a lazy way to achieve what you want. You can customize your greyscale to best suit your usage. Use it as follow:

$("#myImageID").tancolor();

There's an interactive demo. You can play around with it.

Check out the documentation on the usage, it is pretty simple. docs

This should work:

ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
Assembly asm = Assembly.GetCallingAssembly();
String path = Path.GetDirectoryName(new Uri(asm.EscapedCodeBase).LocalPath);

string strLog4NetConfigPath = System.IO.Path.Combine(path, "log4net.config");

I am using this to deploy DLL file libraries along with some configuration file (this is to use log4net from within the DLL file).

I had the same problem on windows "error: failed to execute prompt script (exit code 1) fatal: could not read Username for 'https://github.com': No error" trying to login to github through the login dialog. When I canceled the dialog git asked me for login and password in the command line and it worked fine.

If sql server is installed on your machine, you should check

Programs -> Microsoft SQL Server 20XX -> Configuration Tools -> SQL Server Configuration Manager -> SQL Server Services You'll see "SQL Server (MSSQLSERVER)"

Programs -> Microsoft SQL Server 20XX -> Configuration Tools -> SQL Server Configuration Manager -> SQL Server Network Configuration -> Protocols for MSSQLSERVER -> TCP/IP Make sure it's using port number 1433

If you want to see if the port is open and listening try this from your command prompt... telnet 127.0.0.1 1433

And yes, SQL Express installs use localhost\SQLEXPRESS as the instance name by default.

; This is an example of how a Python Launcher .ini file is structured.

;
;myprog="c:\Program Files\MyCustom.exe" -a -b -c

Thus, on my system I made a py.ini file under c:\windows\ where py.exe exists, with the following contents:

[defaults]
python=3

Now when you Double-click on a .py file, it will be run by the new default version. Now I'm only using the Shebang #! python2 on my old scripts.

Try this:

module Util
module MyUtil



    def self.redondear_up(suma,cantidad, decimales=0)

        unless suma.present?
            return nil
        end


        if suma>0
            resultado= (suma.to_f/cantidad)
            return resultado.round(decimales)
        end


        return nil


    end

end 
end 

Here's how i'd do it:

FN=someletters_12345_moreleters.ext
[[ ${FN} =~ _([[:digit:]]{5})_ ]] && NUM=${BASH_REMATCH[1]}

Explanation:

Bash-specific:

• [[ ]] indicates a conditional expression
• =~ indicates the condition is a regular expression
• && chains the commands if the prior command was successful

Regular Expressions (RE): _([[:digit:]]{5})_

• _ are literals to demarcate/anchor matching boundaries for the string being matched
• () create a capture group
• [[:digit:]] is a character class, i think it speaks for itself
• {5} means exactly five of the prior character, class (as in this example), or group must match

In english, you can think of it behaving like this: the FN string is iterated character by character until we see an _ at which point the capture group is opened and we attempt to match five digits. If that matching is successful to this point, the capture group saves the five digits traversed. If the next character is an _, the condition is successful, the capture group is made available in BASH_REMATCH, and the next NUM= statement can execute. If any part of the matching fails, saved details are disposed of and character by character processing continues after the _. e.g. if FN where _1 _12 _123 _1234 _12345_, there would be four false starts before it found a match.

A quick answer, that doesn't require you to edit any configuration files (and works on other operating systems as well as Windows), is to just find the directory that you are allowed to save to using:

mysql> SHOW VARIABLES LIKE "secure_file_priv";
+------------------+-----------------------+
| Variable_name    | Value                 |
+------------------+-----------------------+
| secure_file_priv | /var/lib/mysql-files/ |
+------------------+-----------------------+
1 row in set (0.06 sec)

And then make sure you use that directory in your SELECT statement's INTO OUTFILE clause:

SELECT *
FROM xxxx
WHERE XXX
INTO OUTFILE '/var/lib/mysql-files/report.csv'
    FIELDS TERMINATED BY '#'
    ENCLOSED BY '"'
    LINES TERMINATED BY '\n'

Original answer

I've had the same problem since upgrading from MySQL 5.6.25 to 5.6.26.

In my case (on Windows), looking at the MySQL56 Windows service shows me that the options/settings file that is being used when the service starts is C:\ProgramData\MySQL\MySQL Server 5.6\my.ini

On linux the two most common locations are /etc/my.cnf or /etc/mysql/my.cnf.

Opening this file I can see that the secure-file-priv option has been added under the [mysqld] group in this new version of MySQL Server with a default value:

secure-file-priv="C:/ProgramData/MySQL/MySQL Server 5.6/Uploads"

You could comment this (if you're in a non-production environment), or experiment with changing the setting (recently I had to set secure-file-priv = "" in order to disable the default). Don't forget to restart the service after making changes.

Alternatively, you could try saving your output into the permitted folder (the location may vary depending on your installation):

SELECT *
FROM xxxx
WHERE XXX
INTO OUTFILE 'C:/ProgramData/MySQL/MySQL Server 5.6/Uploads/report.csv'
    FIELDS TERMINATED BY '#'
    ENCLOSED BY '"'
    LINES TERMINATED BY '\n'

It's more common to have comma seperate values using FIELDS TERMINATED BY ','. See below for an example (also showing a Linux path):

SELECT *
FROM table
INTO OUTFILE '/var/lib/mysql-files/report.csv'
    FIELDS TERMINATED BY ',' ENCLOSED BY '"'
    ESCAPED BY ''
    LINES TERMINATED BY '\n';

.contentWrapper {
    float: left;
    clear: both;
    margin-left: 10%;
    margin-right: 10%;
}

.repeater {
    height: 9em;
    width: 9em;
    float: left;
    margin: 0.2em;
    position: relative;
    text-align: center;
    cursor: pointer;
}

The only way to avoid exception handling is to use the GetNames() method, and we all know that exceptions shouldn't be abused for common application logic :)

If you need to read all values from a section in properties file in a simple manner:

Your config.cfg file layout :

[SECTION_NAME]  
key1 = value1  
key2 = value2  

You code:

   import configparser

   config = configparser.RawConfigParser()
   config.read('path_to_config.cfg file')
    
   details_dict = dict(config.items('SECTION_NAME'))

This will give you a dictionary where keys are same as in config file and their corresponding values.

details_dict is :

{'key1':'value1', 'key2':'value2'}

Now to get key1's value : details_dict['key1']

Putting it all in a method which reads sections from config file only once(the first time the method is called during a program run).

def get_config_dict():
    if not hasattr(get_config_dict, 'config_dict'):
        get_config_dict.config_dict = dict(config.items('SECTION_NAME'))
    return get_config_dict.config_dict

Now call the above function and get the required key's value :

config_details = get_config_dict()
key_1_value = config_details['key1'] 

Generic Multi Section approach:

[SECTION_NAME_1]  
key1 = value1  
key2 = value2  

[SECTION_NAME_2]  
key1 = value1  
key2 = value2

Extending the approach mentioned above, reading section by section automatically and then accessing by section name followed by key name.

def get_config_section():
    if not hasattr(get_config_section, 'section_dict'):
        get_config_section.section_dict = collections.defaultdict()
        
        for section in config.sections():
            get_config_section.section_dict[section] = dict(config.items(section))
    
    return get_config_section.section_dict

To access:

config_dict = get_config_section()

port = config_dict['DB']['port'] 

(here 'DB' is a section name in config file and 'port' is a key under section 'DB'.)

We have M2_HOME,MAVEN_HOME,M3_HOME all are available in market
Previously M2_HOME is the only environment variable used by all as a standard.
But,due latest releases the MAVEN_Home came as standard but some old tools are still trying to find only M2_HOME
so we should have both M2_HOME,MAVEN_HOME to sustain with old and new tools.
M2_HOME can be used for both as well

This is the method Google themselves use in at least one sample:

var markers = [];

// Clear out the old markers.
markers.forEach(function(marker) {
  marker.setMap(null);
});
markers = [];

Check Google sample for complete code example:

https://developers.google.com/maps/documentation/javascript/examples/places-searchbox

This is actually javascript but related/relevant because .querySelectorAll targets by CSS syntax:

var i_will_target_self = document.querySelectorAll("ul.menu li a#example")

this example uses css to target links in a menu with id = "example"

that creates a variable which is a collection of the elements we want to change, but we still have actually change them by setting the new target ("_blank"):

for (var i = 0; i < 5; i++) {
i_will_target_self[i].target = "_blank";
}

That code assumes that there are 5 or less elements. That can be changed easily by changing the phrase "i < 5."

For Windows I found this working:

Set http = CreateObject("Microsoft.XmlHttp")
http.open "GET", "http://www.mywebservice.com/webmethod.asmx?WSDL", FALSE
http.send ""
WScript.Echo http.responseText

Reference: CodeProject

The default data directory for MongoDB is /data/db.

This can be overridden by a dbpath option specified on the command line or in a configuration file.

If you install MongoDB via a package manager such as Homebrew or MacPorts these installs typically create a default data directory other than /data/db and set the dbpath in a configuration file.

If a dbpath was provided to mongod on startup you can check the value in the mongo shell:

db.serverCmdLineOpts()

You would see a value like:

"parsed" : {
    "dbpath" : "/usr/local/data"
},

With the release of TypeScript 3.7, optional chaining (the ? operator) is now officially available.

As such, you can simplify your expression to the following:

const data = change?.after?.data();

You may read more about it from that version's release notes, which cover other interesting features released on that version.

Run the following to install the latest stable release of TypeScript.

npm install typescript

That being said, Optional Chaining can be used alongside Nullish Coalescing to provide a fallback value when dealing with null or undefined values

const data = change?.after?.data() ?? someOtherData();

You might want to try this example for version 2.6 of Python.

def my_print(text, begin, end):
    "Print text in UPPER between 'begin' and 'end' in lower."
    for obj in (text, begin, end):
        assert isinstance(obj, str), 'Argument of wrong type!'
    print begin.lower() + text.upper() + end.lower()

However, have you considered letting the function fail naturally instead?

A lazy way to do this is with the UTF-8 entity code for a half circle \25E0 (aka ◠), which looks like ? and then keyframe animate it. It's a simple as:

.busy
{
animation: spin 1s infinite linear;
display:inline-block;
font-weight: bold;
font-family: sans-serif;
font-size: 35px;
font-style:normal;
color:#555;
}

.busy::before
{
content:"\25E0";
}

@keyframes spin
{
0% {transform: rotate(0deg);}
100% {transform: rotate(359deg);}
}

<i class="busy"></i>

I would do using String#tr :

"1,112".tr(',','').to_i # => 1112

Unless otherwise definied (<tfoot>, <thead>), browsers put <tr> implicitly in a <tbody>.

You need to put a > tbody in between > table and > tr:

$("div.custList > table > tbody > tr")

Alternatively, you can also be less strict in selecting the rows (the > denotes the immediate child):

$("div.custList table tr")

That said, you can get the immediate <td> children there by $(this).children('td').

Or you could have done this:

select trunc(sysdate) - to_date('2009-10-01', 'yyyy-mm-dd') from dual

This returns a NUMBER of whole days:

SQL> create view v as 
  2  select trunc(sysdate) - to_date('2009-10-01', 'yyyy-mm-dd') diff 
  3  from dual;

View created.

SQL> select * from v;

      DIFF
----------
        29

SQL> desc v
 Name                   Null?    Type
 ---------------------- -------- ------------------------
 DIFF                            NUMBER(38)

If you (or a helpful admin) runs Set-ExecutionPolicy as administrator, the policy will be set for all users. (I would suggest "remoteSigned" rather than "unrestricted" as a safety measure.)

NB.: On a 64-bit OS you need to run Set-ExecutionPolicy for 32-bit and 64-bit PowerShell separately.

Add some transition effect to it if you like:

http://jsbin.com/boreme/17/edit?html,css,js

.clearHeader {
  height:50px;
  background:lightblue;
  position:fixed;
  top:0;
  left:0;
  width:100%;

  -webkit-transition: background 2s; /* For Safari 3.1 to 6.0 */
  transition: background 2s;
}

.clearHeader.darkHeader {
 background:#000;
}

I recently started using VMWare Octant https://github.com/vmware-tanzu/octant. This is a better UI than the Kubernetes Dashboard. You can view the Kubernetes cluster and look at the details of the cluster and the PODS. This will allow you to check the logs and open a terminal into the POD(s).

Forget about finding a IDE to write/run/compile assembler on Mac. But, remember mac is UNIX. See http://asm.sourceforge.net/articles/linasm.html. A decent guide (though short) to running assembler via GCC on Linux. You can mimic this. Macs use Intel chips so you want to look at Intel syntax.

Here's an improvement to Hrvoje Hudo's answer. This implementation has a couple of key improvements:

• Cache keys are created automatically based on the function to update data and the object passed in that specifies dependencies
• Pass in time span for any cache duration
• Uses a lock for thread safety

Note that this has a dependency on Newtonsoft.Json to serialize the dependsOn object, but that can be easily swapped out for any other serialization method.

ICache.cs

public interface ICache
{
    T GetOrSet<T>(Func<T> getItemCallback, object dependsOn, TimeSpan duration) where T : class;
}

InMemoryCache.cs

using System;
using System.Reflection;
using System.Runtime.Caching;
using Newtonsoft.Json;

public class InMemoryCache : ICache
{
    private static readonly object CacheLockObject = new object();

    public T GetOrSet<T>(Func<T> getItemCallback, object dependsOn, TimeSpan duration) where T : class
    {
        string cacheKey = GetCacheKey(getItemCallback, dependsOn);
        T item = MemoryCache.Default.Get(cacheKey) as T;
        if (item == null)
        {
            lock (CacheLockObject)
            {
                item = getItemCallback();
                MemoryCache.Default.Add(cacheKey, item, DateTime.Now.Add(duration));
            }
        }
        return item;
    }

    private string GetCacheKey<T>(Func<T> itemCallback, object dependsOn) where T: class
    {
        var serializedDependants = JsonConvert.SerializeObject(dependsOn);
        var methodType = itemCallback.GetType();
        return methodType.FullName + serializedDependants;
    }
}

Usage:

var order = _cache.GetOrSet(
    () => _session.Set<Order>().SingleOrDefault(o => o.Id == orderId)
    , new { id = orderId }
    , new TimeSpan(0, 10, 0)
);

Consider you can't use multiple inheritance in C#, and then look at your question again.

Actually it is the issue related to the app store. I have upload many build some time it takes time depend upon the size of the ipa and at which time you are uploading it to the App Store. Please use Application Loader 3.0 or higher to upload the build.

Here is a more complete looking jquery 1.11.x $.ajax() usage:

<script type="text/javascript">
    function uploadProgressHandler(event) {
        $("#loaded_n_total").html("Uploaded " + event.loaded + " bytes of " + event.total);
        var percent = (event.loaded / event.total) * 100;
        var progress = Math.round(percent);
        $("#uploadProgressBar").html(progress + " percent na ang progress");
        $("#uploadProgressBar").css("width", progress + "%");
        $("#status").html(progress + "% uploaded... please wait");
    }

    function loadHandler(event) {
        $("#status").html(event.target.responseText);
        $("#uploadProgressBar").css("width", "0%");
    }

    function errorHandler(event) {
        $("#status").html("Upload Failed");
    }

    function abortHandler(event) {
        $("#status").html("Upload Aborted");
    }

    $("#uploadFile").click(function (event) {
        event.preventDefault();
        var file = $("#fileUpload")[0].files[0];
        var formData = new FormData();
        formData.append("file1", file);

        $.ajax({
            url: 'http://testarea.local/UploadWithProgressBar1/file_upload_parser.php',
            method: 'POST',
            type: 'POST',
            data: formData,
            contentType: false,
            processData: false,
            xhr: function () {
                var xhr = new window.XMLHttpRequest();
                xhr.upload.addEventListener("progress",
                    uploadProgressHandler,
                    false
                );
                xhr.addEventListener("load", loadHandler, false);
                xhr.addEventListener("error", errorHandler, false);
                xhr.addEventListener("abort", abortHandler, false);

                return xhr;
            }
        });
    });

Building on amimissim's answer, I present a slight alternative, utilising Google's API to handle the events in a cross browser way (amimissim's solution doesn't seem to work in IE8).

I also had to change pac-item.pac-selected to pac-item-refresh.pac-selected as it seems the results div class has changed. This makes pressing ENTER on a suggestion work (rather than selecting the next one down).

var input = document.getElementById('MyFormField');
var autocomplete = new google.maps.places.Autocomplete(input);
google.maps.event.addListener(autocomplete, 'keydown', function(event) {
    var suggestion_selected = $(".pac-item-refesh.pac-selected").length > 0;
    if (event.which == 13 && !suggestion_selected) {
        var simulated_downarrow = $.Event("keydown", {
                    keyCode: 40,
                    which: 40
        });
        this.apply(autocomplete, [simulated_downarrow]);
    }
    this.apply(autocomplete, [event]);
});

We can't because it's expected/required by our customers.

There are many way you can do this. Based on your requirement choose anything from below.

1. By REVERTing commit:

If you want to REVERT all the changes from you last COMMIT that means If you ADD something in your file that will be REMOVED after revert has been done. If you REMOVE something in your file the revert process will ADD those file.

You can REVERT the very last COMMIT. Like:

1.git revert head^
2.git push origin <Branch-Name>

Or you can revert to any previous commit using the hash of that commit.Like:

1.git revert <SHA>
2.git push origin  <Branch-Name>

2. By RESETing previous Head

If you want to just point to any previous commit use reset; it points your local environment back to a previous commit. You can reset your head to previous commit or reset your head to previous any commit.

Reset to previous commit.

1.git reset head^
2.git push -f origin <Branch-name>

Reset to any previous commit:

1.git reset <SHA>
2.git push -f origin <Branch-name>

Trade of between REVERT & RESET:

Why would you choose to do a revert over a reset operation? If you have already pushed your chain of commits to the remote repository (where others may have pulled your code and started working with it), a revert is a nicer way to cancel out changes for them. This is because the Git workflow works well for picking up additional commits at the end of a branch, but it can be challenging if a set of commits is no longer seen in the chain when someone resets the branch pointer back.

saveLeaves(vec,msh);
I'm assuming takes the msh pointer and puts it inside of vec. Since msh is just a pointer to the memory, if you delete it, it will also get deleted inside of the vector.

If you don't have the stdlib then you have to do it manually.

unsigned long hex2int(char *a, unsigned int len)
{
    int i;
    unsigned long val = 0;

    for(i=0;i<len;i++)
       if(a[i] <= 57)
        val += (a[i]-48)*(1<<(4*(len-1-i)));
       else
        val += (a[i]-55)*(1<<(4*(len-1-i)));

    return val;
}

Note: This code assumes uppercase A-F. It does not work if len is beyond your longest integer 32 or 64bits, and there is no error trapping for illegal hex characters.

In order to capture deadlock graphs without using a trace (you don't need profiler necessarily), you can enable trace flag 1222. This will write deadlock information to the error log. However, the error log is textual, so you won't get nice deadlock graph pictures - you'll have to read the text of the deadlocks to figure it out.

I would set this as a startup trace flag (in which case you'll need to restart the service). However, you can run it only for the current running instance of the service (which won't require a restart, but which won't resume upon the next restart) using the following global trace flag command:

DBCC TRACEON(1222, -1);

A quick search yielded this tutorial:

http://www.mssqltips.com/sqlservertip/2130/finding-sql-server-deadlocks-using-trace-flag-1222/

Also note that if your system experiences a lot of deadlocks, this can really hammer your error log, and can become quite a lot of noise, drowning out other, important errors.

Have you considered third party monitoring tools? SQL Sentry Performance Advisor, for example, has a much nicer deadlock graph, showing you object / index names as well as the order in which the locks were taken. As a bonus, these are captured for you automatically on monitored servers without having to configure trace flags, run your own traces, etc.:

Disclaimer: I work for SQL Sentry.

So you´re repeating lots of code within every exception-switch? Sounds like extracting a method would be god idea, doesn´t it?

So your code comes down to this:

MyClass instance;
try { instance = ... }
catch(Exception1 e) { Reset(instance); }
catch(Exception2 e) { Reset(instance); }
catch(Exception) { throw; }

void Reset(MyClass instance) { /* reset the state of the instance */ }

I wonder why no-one noticed that code-duplication.

From C#6 you furthermore have the exception-filters as already mentioned by others. So you can modify the code above to this:

try { ... }
catch(Exception e) when(e is Exception1 || e is Exception2)
{ 
    Reset(instance); 
}

This more verbose solution provides greater control on what happens in case of duplicate maximum value (in this example, it will take one of the corresponding rows randomly)

library(dplyr)
df %>% group_by(A, B) %>%
  mutate(the_rank  = rank(-value, ties.method = "random")) %>%
  filter(the_rank == 1) %>% select(-the_rank)

Box shadows can use commas to have multiple effects, just like with background images (in CSS3).

Thank you @Blorgbeard for the genious idea.

By the way Blorgbeard's query was not working for me so I edited it:

DECLARE @Table_Name as VARCHAR(50) SET @Table_Name = 'MyTable'          -- put here you table name
DECLARE @Column_Like as VARCHAR(20) SET @Column_Like = '%something%'    -- put here you element
DECLARE @sql NVARCHAR(MAX) SET @sql = 'select '

SELECT @sql = @sql + '[' + sys.columns.name + '],'
FROM sys.columns 
JOIN sys.tables ON sys.columns.object_id = tables.object_id
WHERE sys.columns.name like @Column_Like
and sys.tables.name = @Table_Name

SET @sql = left(@sql,len(@sql)-1) -- remove trailing comma
SET @sql = @sql + ' from ' + @Table_Name

EXEC sp_executesql @sql
