You get this error message if a Python file was closed from "the outside", i.e. not from the file object's close() method:

>>> f = open(".bashrc")
>>> os.close(f.fileno())
>>> del f
close failed in file object destructor:
IOError: [Errno 9] Bad file descriptor

The line del f deletes the last reference to the file object, causing its destructor file.__del__ to be called. The internal state of the file object indicates the file is still open since f.close() was never called, so the destructor tries to close the file. The OS subsequently throws an error because of the attempt to close a file that's not open.

Since the implementation of os.system() does not create any Python file objects, it does not seem likely that the system() call is the origin of the error. Maybe you could show a bit more code?

A good example is Javascript. You want this to be at the bottom of the page that is rendered in the browser because this is best practice.

How would you do this from a View based on a Layout/Masterpage where you can only access the middle of the page?

You do this by declaring a Scripts section at the bottom of the Layout page. Then you can add content, in this case Javascript includes (I hope!), from your View page to the bottom of your layout page.

If g++ still gives error Try using:

g++ file.c -lstdc++

Look at this post: What is __gxx_personality_v0 for?

Make sure -lstdc++ is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.

Here's a sample code:

Exec sp_add_schedule
    @schedule_name = N'SchedulName' 
    @freq_type = 1
    @active_start_time = 08300

For everyone using editors like Komodo Edit (win10) add sys.stdout.flush() to:

def mp_worker((inputs, the_time)):
    print " Process %s\tWaiting %s seconds" % (inputs, the_time)
    time.sleep(int(the_time))
    print " Process %s\tDONE" % inputs
    sys.stdout.flush()

or as first line to:

    if __name__ == '__main__':
       sys.stdout.flush()

This helps to see what goes on during the run of the script; in stead of having to look at the black command line box.

docker-push-ssh is a command line utility I created just for this scenario.

It sets up a temporary private Docker registry on the server, establishes an SSH tunnel from your localhost, pushes your image, then cleans up after itself.

The benefit of this approach over docker save (at the time of writing most answers are using this method) is that only the new layers are pushed to the server, resulting in a MUCH quicker upload.

Oftentimes using an intermediate registry like dockerhub is undesirable, and cumbersome.

https://github.com/brthor/docker-push-ssh

Install:

pip install docker-push-ssh

Example:

docker-push-ssh -i ~/my_ssh_key [email protected] my-docker-image

The biggest caveat is that you have to manually add your localhost to Docker's insecure_registries configuration. Run the tool once and it will give you an informative error:

Error Pushing Image: Ensure localhost:5000 is added to your insecure registries.

It's not as simple as just omitting the return keyword. In Scala, if there is no return then the last expression is taken to be the return value. So, if the last expression is what you want to return, then you can omit the return keyword. But if what you want to return is not the last expression, then Scala will not know that you wanted to return it.

An example:

def f() = {
  if (something)
    "A"
  else
    "B"
}

Here the last expression of the function f is an if/else expression that evaluates to a String. Since there is no explicit return marked, Scala will infer that you wanted to return the result of this if/else expression: a String.

Now, if we add something after the if/else expression:

def f() = {
  if (something)
    "A"
  else
    "B"

  if (somethingElse)
    1
  else
    2
}

Now the last expression is an if/else expression that evaluates to an Int. So the return type of f will be Int. If we really wanted it to return the String, then we're in trouble because Scala has no idea that that's what we intended. Thus, we have to fix it by either storing the String to a variable and returning it after the second if/else expression, or by changing the order so that the String part happens last.

Finally, we can avoid the return keyword even with a nested if-else expression like yours:

def f() = {
  if(somethingFirst) {
    if (something)      // Last expression of `if` returns a String
     "A"
    else
     "B"
  }
  else {
    if (somethingElse)
      1
    else
      2

    "C"                // Last expression of `else` returns a String
  }

}

Some x86 instructions are designed to leave the content of the operands (registers) as they are and just set/unset specific internal CPU flags like the zero-flag (ZF). You can think at the ZF as a true/false boolean flag that resides inside the CPU.

in this particular case, TEST instruction performs a bitwise logical AND, discards the actual result and sets/unsets the ZF according to the result of the logical and: if the result is zero it sets ZF = 1, otherwise it sets ZF = 0.

Conditional jump instructions like JE are designed to look at the ZF for jumping/notjumping so using TEST and JE together is equivalent to perform a conditional jump based on the value of a specific register:

example:

TEST EAX,EAX
JE some_address

the CPU will jump to "some_address" if and only if ZF = 1, in other words if and only if AND(EAX,EAX) = 0 which in turn it can occur if and only if EAX == 0

the equivalent C code is:

if(eax == 0)
{
    goto some_address
}

<title>Index.html</title>

    var varDeclaration = true;
    noVarDeclaration = true;
    window.hungOnWindow = true;
    document.hungOnDocument = true;
</script>

/* external.js */

console.info(varDeclaration == true); // could be .log, alert etc
// returns false in IE8

console.info(noVarDeclaration == true); // could be .log, alert etc
// returns false in IE8

console.info(window.hungOnWindow == true); // could be .log, alert etc
// returns true in IE8

console.info(document.hungOnDocument == true); // could be .log, alert etc
// returns ??? in IE8 (untested!)  *I personally find this more clugy than hanging off window obj

Is there a global object that all vars are hung off of by default? eg: 'globals.noVar declaration'

In my case I have to concatenate the certs of my domain.

cat myDomain.crt EntityCertCA.crt TrustedRoot.crt > bundle.crt

Restart the service and all ok.

systemctl restart nginx.service

You can use .map().

Pass each element in the current matched set through a function, producing a new jQuery object containing the return value.

As the return value is a jQuery object, which contains an array, it's very common to call .get() on the result to work with a basic array.

Use

var arr = $('input[name="pname[]"]').map(function () {
    return this.value; // $(this).val()
}).get();

That's not possible with CSS, you will have to use the Javascript for that. Although you can set the width of the p to as much as 30 characters and next letters will automatically come down but again this won't be that accurate and will vary if the characters are in capital.

This answer provides detailed steps on how to achieve that relatively easily:

There is definitely a way to do this -- use X() macros. These macros use the C preprocessor to construct enums, arrays and code blocks from a list of source data. You only need to add new items to the #define containing the X() macro. The switch statement would expand automatically.

Your example can be written as follows:

 // Source data -- Enum, String
 #define X_NUMBERS \
    X(ONE,   "one") \
    X(TWO,   "two") \
    X(THREE, "three")

 ...

 // Use preprocessor to create the Enum
 typedef enum {
  #define X(Enum, String)       Enum,
   X_NUMBERS
  #undef X
 } Numbers;

 ...

 // Use Preprocessor to expand data into switch statement cases
 switch(num)
 {
 #define X(Enum, String) \
     case Enum:  strcpy(num_str, String); break;
 X_NUMBERS
 #undef X

     default: return 0; break;
 }
 return 1;

There are more efficient ways (i.e. using X Macros to create an string array and enum index), but this is the simplest demo.

One way to solve this problem is by turning the warnings off.

SET ANSI_WARNINGS OFF;

For Query parameters like domain.com/test?format=json&type=mini format, then you can easily receive it via - req.query.

app.get('/test', function(req, res){
  var format = req.query.format,
      type = req.query.type;
});

The optimiser will judge if the use of your index will make your query run faster, and if it is, it will use the index.

Depending on your RDBMS you can force the use of an index, although it is not recommended unless you know what you are doing.

In general you should index columns that you use in table join's and where statements

There's no need for the outer try in your example, so you can at least go down from 3 to 2, and also you don't need closing ; at the end of the resource list. The advantage of using two try blocks is that all of your code is present up front so you don't have to refer to a separate method:

public List<User> getUser(int userId) {
    String sql = "SELECT id, username FROM users WHERE id = ?";
    List<User> users = new ArrayList<>();
    try (Connection con = DriverManager.getConnection(myConnectionURL);
         PreparedStatement ps = con.prepareStatement(sql)) {
        ps.setInt(1, userId);
        try (ResultSet rs = ps.executeQuery()) {
            while(rs.next()) {
                users.add(new User(rs.getInt("id"), rs.getString("name")));
            }
        }
    } catch (SQLException e) {
        e.printStackTrace();
    }
    return users;
}

A perspective from 2019:

AWS Lambda now supports Python 3.7, which many people (including myself) choose to use as the runtime for inline lambdas.

Then I had to import an external dependency and I followed AWS Docs as the OP referred to. (local install --> zip --> upload).

I had the import module error and I realised my local PC had Python 2.7 as the default Python. When I invoked pip, it installed my dependency for Python 2.7.

So I switched locally to the Python version that matches the selected runtime version in the lambda console and then re-installed the external dependencies. This solved the problem for me. E.g.:

$ python3 -m pip install --target path/to/lambda_file <external_dependency_name>

Take a look in error file for your mysql database. According to Bug #26305 my sql do not give you the cause. This bug exists since MySQL 4.1 ;-)

Sometimes it is very convenient to use stringstream to convert between strings and other numerical types. The usage of stringstream is similar to the usage of iostream, so it is not a burden to learn.

Stringstreams can be used to both read strings and write data into strings. It mainly functions with a string buffer, but without a real I/O channel.

The basic member functions of stringstream class are

• str(), which returns the contents of its buffer in string type.

• str(string), which set the contents of the buffer to the string argument.

Here is an example of how to use string streams.

ostringstream os;
os << "dec: " << 15 << " hex: " << std::hex << 15 << endl;
cout << os.str() << endl;

The result is dec: 15 hex: f.

istringstream is of more or less the same usage.

To summarize, stringstream is a convenient way to manipulate strings like an independent I/O device.

FYI, the inheritance relationships between the classes are:

My Solution - Java - Without duplicates

    public static void printAllPairSum(int[] a, int x){
    System.out.printf("printAllPairSum(%s,%d)\n", Arrays.toString(a),x);
    if(a==null||a.length==0){
        return;
    }
    int length = a.length;
    Map<Integer,Integer> reverseMapOfArray = new HashMap<>(length,1.0f);
    for (int i = 0; i < length; i++) {
        reverseMapOfArray.put(a[i], i);
    }

    for (int i = 0; i < length; i++) {
        Integer j = reverseMapOfArray.get(x - a[i]);
        if(j!=null && i<j){
            System.out.printf("a[%d] + a[%d] = %d + %d = %d\n",i,j,a[i],a[j],x);
        }
    }
    System.out.println("------------------------------");
}

Easiest approach, Run Count(*) query, do resultSet.next() to point to the first row and then just do resultSet.getString(1) to get the count. Code :

ResultSet rs = statement.executeQuery("Select Count(*) from your_db");
if(rs.next()) {
   int count = rs.getString(1).toInt()
}

update the server arguments from -Dhttps.protocols=SSLv3 to -Dhttps.protocols=TLSv1,SSLv3

The question relates to serving via artisan and so Jrop's answer is ideal in that case. I.e, error_log logging to the apache log.

However, if your serving via a standard web server then simply use the Laravel specific logging functions:

\Log::info('This is some useful information.');

\Log::warning('Something could be going wrong.');

\Log::error('Something is really going wrong.');

With current versions of laravel like this for info:

info('This is some useful information.');

This logs to Laravel's log file located at /laravel/storage/logs/laravel-<date>.log (laravel 5.0). Monitor the log - linux/osx: tail -f /laravel/storage/logs/laravel-<date>.log

Here is a solution using dplyr >= 0.5.

library(dplyr)
set.seed(123)
df <- data.frame(
  x = sample(0:1, 10, replace = T),
  y = sample(0:1, 10, replace = T),
  z = 1:10
)

> df %>% distinct(x, y, .keep_all = TRUE)
    x y z
  1 0 1 1
  2 1 0 2
  3 1 1 4

In my similar case, I had my own validation logic and just wanted to use jQuery validation to show the message. This was what I did.

//1) Enable jQuery validation_x000D_
var validator = $('#myForm').validate();_x000D_
_x000D_
$('#myButton').click(function(){_x000D_
  //my own validation logic here_x000D_
  //....._x000D_
  //2) when validation failed, show the error message manually_x000D_
  validator.showErrors({_x000D_
    'myField': 'my custom error message'_x000D_
  });_x000D_
});

I don't know if this works but I made the variable names

public abstract class beep implements ActionListener {
    public static void main(String[] args) {
        JFrame f = new JFrame("beeper");
        JButton button = new JButton("Beep me");
        f.setVisible(true);
        f.setSize(300, 200);
        f.add(button);
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                // Insert code here
            }
        });
    }
}

There is some basic pattern matching available through using LIKE, where % matches any number and combination of characters, _ matches any one character, and [abc] could match a, b, or c... There is more info on the MSDN site.

Although this popular answer will give you your desired indexing syntax, it is doubly inefficient: big and slow both in space and time. There's a better way.

Why That Answer is Big and Slow

The proposed solution is to create a dynamic array of pointers, then initializing each pointer to its own, independent dynamic array. The advantage of this approach is that it gives you the indexing syntax you're used to, so if you want to find the value of the matrix at position x,y, you say:

int val = matrix[ x ][ y ];

This works because matrix[x] returns a pointer to an array, which is then indexed with [y]. Breaking it down:

int* row = matrix[ x ];
int  val = row[ y ];

Convenient, yes? We like our [ x ][ y ] syntax.

But the solution has a big disadvantage, which is that it is both fat and slow.

Why?

The reason that it's both fat and slow is actually the same. Each "row" in the matrix is a separately allocated dynamic array. Making a heap allocation is expensive both in time and space. The allocator takes time to make the allocation, sometimes running O(n) algorithms to do it. And the allocator "pads" each of your row arrays with extra bytes for bookkeeping and alignment. That extra space costs...well...extra space. The deallocator will also take extra time when you go to deallocate the matrix, painstakingly free-ing up each individual row allocation. Gets me in a sweat just thinking about it.

There's another reason it's slow. These separate allocations tend to live in discontinuous parts of memory. One row may be at address 1,000, another at address 100,000—you get the idea. This means that when you're traversing the matrix, you're leaping through memory like a wild person. This tends to result in cache misses that vastly slow down your processing time.

So, if you absolute must have your cute [x][y] indexing syntax, use that solution. If you want quickness and smallness (and if you don't care about those, why are you working in C++?), you need a different solution.

A Different Solution

The better solution is to allocate your whole matrix as a single dynamic array, then use (slightly) clever indexing math of your own to access cells. The indexing math is only very slightly clever; nah, it's not clever at all: it's obvious.

class Matrix
{
    ...
    size_t index( int x, int y ) const { return x + m_width * y; }
};

Given this index() function (which I'm imagining is a member of a class because it needs to know the m_width of your matrix), you can access cells within your matrix array. The matrix array is allocated like this:

array = new int[ width * height ];

So the equivalent of this in the slow, fat solution:

array[ x ][ y ]

...is this in the quick, small solution:

array[ index( x, y )]

Sad, I know. But you'll get used to it. And your CPU will thank you.

<?php 
$j=1;
?>
<script>
var i = "<?php echo $j; ?>";
//Do something
</script>
<?php
echo $j;
?>

This is the easiest way of passing a php variable to javascript without Ajax.

You can also use something like this:

var i = "<?php echo json_encode($j); ?>";

This said to be safer or more secure. i think

You can use markersize to specify the size of the circle in plot method

import numpy as np
import matplotlib.pyplot as plt

x1 = np.random.randn(20)
x2 = np.random.randn(20)
plt.figure(1)
# you can specify the marker size two ways directly:
plt.plot(x1, 'bo', markersize=20)  # blue circle with size 10 
plt.plot(x2, 'ro', ms=10,)  # ms is just an alias for markersize
plt.show()

From here

I did this a bit different. In my gridview I set the AutoGenerateDeleteButton="true". To find the delete button I use jQuery and add a click event to the found Anchors.

jQuery("a").filter(function () {
        return this.innerHTML.indexOf("Delete") == 0;
        }).click(function () { return confirm("Are you sure you want to delete this record?"); 
});

This is quick and simple for what I need to do. Just be mindful that Every Anchor in the page that displays Delete will be selected by jQuery and will have the event added to it.

The catch all for me is taking an object, encoding it, and then passing the string into a javascript script tag. To do this you have to do some replacements.

First replace every \ with a double slash \\ and then every quote" with a \".

$payload = json_encode($payload);
$payload = preg_replace("_\\\_", "\\\\\\", $payload);
$payload = preg_replace("/\"/", "\\\"", $payload);
return View::make('pages.javascript')
  ->with('payload', $payload)

Then in the blade template

@if(isset($payload))
<script>
  window.__payload = JSON.parse("{!!$payload!!}");
</script>
@endif

This basically allows you to take an object on the php side, and then have an object on the javascript side.

In My case I have't define all variables which I am passing to data in ajax.

var page = 1;

$.ajax({
    url: 'your_url',
    type: "post",
    data: { 'page' : page, 'search_candidate' : search_candidate }
    success: function(result){
        alert('function called');
    }
)}

I have just defined variable var search_candidate = "candidate name"; and its working.

var page = 1;
var search_candidate = "candidate name"; // defined
$.ajax({
    url: 'your_url',
    type: "post",
    data: { 'page' : page, 'search_candidate' : search_candidate }
    success: function(result){
        alert('function called');
    }
)}

Well, the above answer is correct, auto_now_add and auto_now would do it, but it would be better to make an abstract class and use it in any model where you require created_at and updated_at fields.

class TimeStampMixin(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    class Meta:
        abstract = True

Now anywhere you want to use it you can do a simple inherit and you can use timestamp in any model you make like.

class Posts(TimeStampMixin):
    name = models.CharField(max_length=50)
    ...
    ...

In this way, you can leverage object-oriented reusability, in Django DRY(don't repeat yourself)

Instead of using jQuery, use css property text-overflow:ellipsis. It will automatically truncate the string.

.truncated { display:inline-block; 
             max-width:100px; 
             overflow:hidden; 
             text-overflow:ellipsis; 
             white-space:nowrap; 
           }

This is neither an exact answer to the question nor a silver bullet. However, if nothing works for you e.g. Invalidate cache & restart, Checking build dependency, Disabling Instant Run (I never advise that) etc.

1. Add command-line option --stacktrace in Setting > Build, Execution, Deployment > Compiler
2. Now build/assemble gradle once again. You will have detailed information about the cause. e.g. in my case:

Caused by: org.gradle.internal.resolve.ModuleVersionNotFoundException: Could not find com.squareup.okhttp3:logging-interceptor:3.9.1Net.

I have misspelled the dependency name in module level gradle file. Hope that help

It's to simple you can use this code for capture the screenshot of particular area you have to define the div id in html2canvas. I'm using here 2 div-:

div id="car"
div id ="chartContainer"
if you want to capture only cars then use car i'm capture here car only you can change chartContainer for capture the graph html2canvas($('#car') copy and paste this code

You can see if it's really not set. Run the command set | grep TERM.

If not, you can set it like that: export TERM=xterm

Let's say you placed all the other files and directories in a folder named 'locale'.

Just go to index.php and find these two lines:

require __DIR__.'/../bootstrap/autoload.php';

$app = require_once __DIR__.'/../bootstrap/app.php';

and change them to this:

require __DIR__.'/locale/bootstrap/autoload.php';

$app = require_once __DIR__.'/locale/bootstrap/app.php';

Go to management studio and run sp_helpdb <db_name>, it will give detailed disk usage for the specified database. Running it without any parameter values will list high level information for all databases in the instance.

In case you'd like to paste windows path from other source (say, File Explorer) - you can do so via input() call in python console:

>>> input()
D:\EP\stuff\1111\this_is_a_long_path\you_dont_want\to_type\or_edit_by_hand
'D:\\EP\\stuff\\1111\\this_is_a_long_path\\you_dont_want\\to_type\\or_edit_by_hand'

Then just copy the result

Let's use the latest fat arrow functions:

navigator.geolocation.getCurrentPosition((loc) => {
  console.log('The location in lat lon format is: [', loc.coords.latitude, ',', loc.coords.longitude, ']');
})

I also experienced the same thing. I found out that my favicon.ico had not been processed as a legitimate shortcut icon. I understand that favicons must be scaled to 16x16 and follow the Microsoft Icon format.

you can also use the Readonly attribute: the input is not gonna be grayed but it won't be editable

<input type="text" name="lat" value="22.2222" readonly="readonly" />

Why not fix a <video> and use z-index:-1 to put it behind all other elements?

html, body { width:100%; height:100%; margin:0; padding:0; }

<div style="position: fixed; top: 0; width: 100%; height: 100%; z-index: -1;">
    <video id="video" style="width:100%; height:100%">
        ....
    </video>
</div>
<div class='content'>
    ....

Demo

If you want it within a container you have to add a container element and a little more CSS

/* HTML */
<div class='vidContain'>
    <div class='vid'>
        <video> ... </video>
    </div>
    <div class='content'> ... The rest of your content ... </div>
</div>

/* CSS */
.vidContain {
    width:300px; height:200px;
    position:relative;
    display:inline-block;
    margin:10px;
}
.vid {
    position: absolute; 
    top: 0; left:0;
    width: 100%; height: 100%; 
    z-index: -1;
}    
.content {
    position:absolute;
    top:0; left:0;
    background: black;
    color:white;
}

Demo

You can do this natively as follows:

1. Select the table and use Excel to sort it on Last Name
2. Create a 2-row by 1-column advanced filter criteria, say in E1 and E2, where E1 is empty and E2 contains the formula =C6="" where C6 is the first data cell of the phone number column.
3. Select the table and use advanced filter, copy to a range, using the criteria range in E1:E2 and specify where you want to copy the output to

If you want to do this programmatically I suggest you use the Macro Recorder to record the above steps and look at the code.

Try this:

onclick="myfunction(
    '/myController/myAction',
    function(){myfuncionOnOK('/myController2/myAction2','myParameter2');},
    function(){myfuncionOnCancel('/myController3/myAction3','myParameter3');}
);"

Then you just need to call these two functions passed to myfunction:

function myfunction(url, f1, f2) {
    // …
    f1();
    f2();
}

The key checks for FAST REFRESH includes the following:

1) An Oracle materialized view log must be present for each base table.
2) The RowIDs of all the base tables must appear in the SELECT list of the MVIEW query definition.
3) If there are outer joins, unique constraints must be placed on the join columns of the inner table.

No 3 is easy to miss and worth highlighting here

Your result will vary depending on what kind of terminal or console program you're on, but yes, on most \b is a nondestructive backspace. It moves the cursor backward, but doesn't erase what's there.

So for the hello worl part, the code outputs

hello worl
          ^

...(where ^ shows where the cursor is) Then it outputs two \b characters which moves the cursor backward two places without erasing (on your terminal):

hello worl
        ^

Note the cursor is now on the r. Then it outputs d, which overwrites the r and gives us:

hello wodl
         ^

Finally, it outputs \n, which is a non-destructive newline (again, on most terminals, including apparently yours), so the l is left unchanged and the cursor is moved to the beginning of the next line.

Based on my tests (Win7 64bit, 6GB RAM, Java6), NIO transferFrom is fast only with small files and becomes very slow on larger files. NIO databuffer flip always outperforms standard IO.

• Copying 1000x2MB

  1. NIO (transferFrom) ~2300ms
  2. NIO (direct datababuffer 5000b flip) ~3500ms
  3. Standard IO (buffer 5000b) ~6000ms

• Copying 100x20mb

  1. NIO (direct datababuffer 5000b flip) ~4000ms
  2. NIO (transferFrom) ~5000ms
  3. Standard IO (buffer 5000b) ~6500ms

• Copying 1x1000mb

  1. NIO (direct datababuffer 5000b flip) ~4500s
  2. Standard IO (buffer 5000b) ~7000ms
  3. NIO (transferFrom) ~8000ms

The transferTo() method works on chunks of a file; wasn't intended as a high-level file copy method: How to copy a large file in Windows XP?

While I share the concerns regarding Java replacements for free-form SQL queries, I really do think people criticizing ORM are doing so because of a generally poor application design.

True OOD is driven by classes and relationships, and ORM gives you consistent mapping of different relationship types and objects. If you use an ORM tool and end up coding query expressions in whatever query language the ORM framework supports (including, but not limited to Java expression trees, query methods, OQL etc.), you are definitely doing something wrong, i.e. your class model most likely doesn't support your requirements in the way it should. A clean application design doesn't really need queries on the application level. I've been refactoring many projects people started out using an ORM framework in the same way as they were used to embed SQL string constants in their code, and in the end everyone was suprised about how simple and maintainable the whole application gets once you match up your class model with the usage model. Granted, for things like search functionality etc. you need a query language, but even then queries are so much constrained that creating an even complex VIEW and mapping that to a read-only persistent class is much nicer to maintain and look at than building expressions in some query language in the code of your application. The VIEW approach also leverages database capabilities and, via materialization, can be much better performance-wise than any hand-written SQL in your Java source. So, I don't see any reason for a non-trivial application NOT to use ORM.

Now that Firefox Quantum 57 is out with substantial — and potentially breaking — improvements to Gecko collectively known as Stylo or Quantum CSS, you may find yourself in a situation where you have to distinguish between legacy versions of Firefox and Firefox Quantum.

From my answer here:

You can use @supports with a calc(0s) expression in conjunction with @-moz-document to test for Stylo — Gecko does not support time values in calc() expressions but Stylo does:

@-moz-document url-prefix() {
  @supports (animation: calc(0s)) {
    /* Stylo */
  }
}

Here's a proof-of-concept:

_x000D_

_x000D_

body::before {_x000D_
  content: 'Not Fx';_x000D_
}_x000D_
_x000D_
@-moz-document url-prefix() {_x000D_
  body::before {_x000D_
    content: 'Fx legacy';_x000D_
  }_x000D_
_x000D_
  @supports (animation: calc(0s)) {_x000D_
    body::before {_x000D_
      content: 'Fx Quantum';_x000D_
    }_x000D_
  }_x000D_
}

_x000D_

_x000D_

_x000D_

Targeting legacy versions of Firefox is a little tricky — if you're only interested in versions that support @supports, which is Fx 22 and up, @supports not (animation: calc(0s)) is all you need:

@-moz-document url-prefix() {
  @supports not (animation: calc(0s)) {
    /* Gecko */
  }
}

... but if you need to support even older versions, you'll need to make use of the cascade, as demonstrated in the proof-of-concept above.

Just to add another situation where this can happen:

I had the code:

NSMutableString *string;
[string   appendWithFormat:@"foo"];

Obviously I had forgotten to allocate memory for the string:

NSMutableString *string = [[NSMutableString alloc] init];
[string   appendWithFormat:@"foo"];

fixes the problem.

It seems that Bootstrap doesn't support disabled links. Instead of trying to add a Bootstrap class, you could add a class by your own and add some styling to it, just like this:

a.disabled {_x000D_
  /* Make the disabled links grayish*/_x000D_
  color: gray;_x000D_
  /* And disable the pointer events */_x000D_
  pointer-events: none;_x000D_
}

<!-- Make the disabled links unfocusable as well -->_x000D_
<a href="#" class="disabled" tabindex="-1">Link to disable</a><br/>_x000D_
<a href="#">Non-disabled Link</a>

Or, as an alternative to @Chase's code, being a recent plyr fan with a background in databases:

zz[is.na(zz)] <- 0

I came across this in PHP when using fopen() on a file and then trying to unlink() it before using fclose() on it.

No good:

$handle = fopen('file.txt');
// do something
unlink('file.txt');

Good:

$handle = fopen('file.txt');
// do something
fclose($handle);
unlink('file.txt');

For Windows users: 1.Install the full version of MYSQL 2.On the Windows 10 start button click on search and type in MySQL 3. Select the MYSQL Command Line Client 5.5 (I am using version 5.5) 4. go ahead and run your sql queries/ 5. to exit type \q or quit

To capitalize on the answer of Alex D, using refinements:

module CoreExtensions
  module Integerable
    refine String do
      def integer?
        Integer(self)
      rescue ArgumentError
        false
      else
        true
      end
    end
  end
end

Later, in you class:

require 'core_ext/string/integerable'

class MyClass
  using CoreExtensions::Integerable

  def method
    'my_string'.integer?
  end
end

Besides aws_access_key_id and aws_secret_access_key, I also added aws_session_token in credentials, it works for me

There are two ways, depending on your original timestamp:

mktime() and timegm()

http://docs.python.org/library/time.html

Don't use list as a variable name for it shadows the builtin.

And there is no need to determine the length of the list. Just iterate over it.

def printer(data):
    for element in data:
        print(element[0])

Just an addendum: Looking at the contents of the inner lists I think they might be the wrong data structure. It looks like you want to use a dictionary instead.

Use File Explorer in eclipse. Select Windows => Show View => Other ... => File Explorer.

An another way is pull the file via adb:

adb pull /system/data/data/<yourpackagename>/databases/<databasename> /sdcard

IMHO the accepted answer is correct but misses some 'teaching' as it does not explain how to come up with the answer. For all deprecated classes look at the JavaDoc (if you do not have it either download it or go online), it will hint at which class to use to replace the old code. Of course it will not tell you everything, but this is a start. Example:

...
 *
 * @deprecated (4.3) use {@link HttpClientBuilder}.  <----- THE HINT IS HERE !
 */
@ThreadSafe
@Deprecated
public class DefaultHttpClient extends AbstractHttpClient {

Now you have the class to use, HttpClientBuilder, as there is no constructor to get a builder instance you may guess that there must be a static method instead: create. Once you have the builder you can also guess that as for most builders there is a build method, thus:

org.apache.http.impl.client.HttpClientBuilder.create().build();

AutoClosable:

As Jules hinted in the comments, the returned class implements java.io.Closable, so if you use Java 7 or above you can now do:

    try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {...}

The advantage is that you do not have to deal with finally and nulls.

Also make sure to read about connection pooling and set the timeouts.

You will not find such function in standard Python libraries, while this function is Windows specific. However if you use ActiveState Python, or just install win32api module to standard Python Windows installation you can use:

x, y = win32api.GetCursorPos()

So I found it out by myself. It is actually a pretty simple but powerful concept. It has to do with code reuse as in the example below. Basically, the idea is to extract common and / or context specific chunks of code in order to clean up the models and avoid them getting too fat and messy.

As an example, I'll put one well known pattern, the taggable pattern:

# app/models/product.rb
class Product
  include Taggable

  ...
end

# app/models/concerns/taggable.rb
# notice that the file name has to match the module name 
# (applying Rails conventions for autoloading)
module Taggable
  extend ActiveSupport::Concern

  included do
    has_many :taggings, as: :taggable
    has_many :tags, through: :taggings

    class_attribute :tag_limit
  end

  def tags_string
    tags.map(&:name).join(', ')
  end

  def tags_string=(tag_string)
    tag_names = tag_string.to_s.split(', ')

    tag_names.each do |tag_name|
      tags.build(name: tag_name)
    end
  end

  # methods defined here are going to extend the class, not the instance of it
  module ClassMethods

    def tag_limit(value)
      self.tag_limit_value = value
    end

  end

end

So following the Product sample, you can add Taggable to any class you desire and share its functionality.

This is pretty well explained by DHH:

In Rails 4, we’re going to invite programmers to use concerns with the default app/models/concerns and app/controllers/concerns directories that are automatically part of the load path. Together with the ActiveSupport::Concern wrapper, it’s just enough support to make this light-weight factoring mechanism shine.

you can also try this

print ''.join(file('example.txt'))

CellSpacing as the name suggests it is the Space between the Adjacent cells and CellPadding on the other hand means the padding around the cell content.

You can use selenium and the webdriver for Firefox.

import selenium.webdriver
import selenium.common

options = selenium.webdriver.firefox.options.Options()
# options.headless = True
with selenium.webdriver.Firefox(options=options) as driver:
    driver.get('http://google.com')
    time.sleep(2)
    root=driver.find_element_by_tag_name('html')
    root.screenshot('whole page screenshot.png')

Use std::size_t for indexing/counting C-style arrays.

For STL containers, you'll have (for example) vector<int>::size_type, which should be used for indexing and counting vector elements.

In practice, they are usually both unsigned ints, but it isn't guaranteed, especially when using custom allocators.

Not certain what the HTML looks like (that would help with answers). If it's

<div class="testimonials content">stuff</div>

then simply remove the space in your css. A la...

.testimonials.content { css here }

UPDATE:

Okay, after seeing HTML see if this works...

.testimonials .wrapper .content { css here }

or just

.testimonials .wrapper { css here }

or

.desc-container .wrapper { css here }

all 3 should work.

You set DockPanel.Dock="Top" to the StackPanel, but the StackPanel is not a child of the DockPanel... the Border is. Your docking property is being ignored.

If you move DockPanel.Dock="Top" to the Border instead, both of your problems will be fixed :)

The first one

f = lambda x: x*x
[f(x) for x in range(10)]

runs f() for each value in the range so it does f(x) for each value

the second one

[lambda x: x*x for x in range(10)]

runs the lambda for each value in the list, so it generates all of those functions.

I had the app with multiple subdomains and session cookie was the problem between those. Clearing the cookies resolved my problem.

Also, try setting the SESSION_DOMAIN in .env file. Use the exact subdomain you are browsing.

Just a modification in above answer. Simply run this command to install mysql for python

sudo yum install MySQL-python
sudo apt-get install MySQL-python

remember! It is case sensitive.

When I develop, it's on a different domain within a folder. When I take a site live, that folder doesn't exist anymore. Using RewriteBase allows me to use the same .htaccess file in both environments.

When live:

RewriteBase /
# RewriteBase /dev_folder/

When developing:

# RewriteBase /
RewriteBase /dev_folder/

Use Apache Friends XAMPP. It will set up Apache HTTP server, PHP 5 and MySQL 5 (as far as I know, there's probably some more than that). You don't need to know how to configure apache (or any of the modules) to use it.

You will have an htdocs directory which Apache will serve (accessible by http://localhost/) and should be able to put your PHP files there. With my installation, it is at C:\xampp\htdocs.

the question is should the url be case sensitive?

I see no use, or good practice behind case sensitive URL's. It stupid, it sucks and should be avoided at all times.

Just to back up my opinion, when someone asks what URL, how could you explain what characters of the URL are Upper or Lower case? That's nonsense and should no one ever tell you otherwise.

Simply in the "Find what:" field, type \r. This means "Ends of the Row". In the "Replace with:" field, you put what you want for instance .xml

if you have several lines, and you are aiming to add that text to the end of the each line, you need to markup the option ". matches newline" in the "Search Mode" group box.

Example:

You have a file name list, but you want to add an extension like .xml. This would be what you need to do and Bang! One shot!:

Python 3.4 and later offer pathlib in the standard library. You could do:

from pathlib import Path

asm_pths = [pth for pth in Path.cwd().iterdir()
            if pth.suffix == '.asm']

Or if you don't like list comprehensions:

asm_paths = []
for pth in Path.cwd().iterdir():
    if pth.suffix == '.asm':
        asm_pths.append(pth)

Path objects can easily be converted to strings.

Move pod members to a base class to shorten your initializer list:

struct foo_pod
{
    int x;
    int y;
    int z;
};

struct foo : foo_pod
{
    std::string name;
    foo(std::string name)
        : foo_pod()
        , name(name)
    {
    }
};

int main()
{
    foo f("bar");
    printf("%d %d %d %s\n", f.x, f.y, f.z, f.name.c_str());
}

In addition to existing good answers, note that Jackson 1.9 improved handling by adding "property unification", meaning that ALL annotations from difference parts of a logical property are combined, using (hopefully) intuitive precedence.

In Jackson 1.8 and prior, only field and getter annotations were used when determining what and how to serialize (writing JSON); and only and setter annotations for deserialization (reading JSON). This sometimes required addition of "extra" annotations, like annotating both getter and setter.

With Jackson 1.9 and above these extra annotations are NOT needed. It is still possible to add those; and if different names are used, one can create "split" properties (serializing using one name, deserializing using other): this is occasionally useful for sort of renaming.

There's a strong chance that the privileges to select from table1 have been granted to a role, and the role has been granted to you. Privileges granted to a role are not available to PL/SQL written by a user, even if the user has been granted the role.

You see this a lot for users that have been granted the dba role on objects owned by sys. A user with dba role will be able to, say, SELECT * from V$SESSION, but will not be able to write a function that includes SELECT * FROM V$SESSION.

The fix is to grant explicit permissions on the object in question to the user directly, for example, in the case above, the SYS user has to GRANT SELECT ON V_$SESSION TO MyUser;

The copy command is a SQL*Plus command (not a SQL Developer command). If you have your tnsname entries setup for SID1 and SID2 (e.g. try a tnsping), you should be able to execute your command.

Another assumption is that table1 has the same columns as the message_table (and the columns have only the following data types: CHAR, DATE, LONG, NUMBER or VARCHAR2). Also, with an insert command, you would need to be concerned about primary keys (e.g. that you are not inserting duplicate records).

I tried a variation of your command as follows in SQL*Plus (with no errors):

copy from scott/tiger@db1 to scott/tiger@db2 create new_emp using select * from emp;

After I executed the above statement, I also truncate the new_emp table and executed this command:

copy from scott/tiger@db1 to scott/tiger@db2 insert new_emp using select * from emp;

With SQL Developer, you could do the following to perform a similar approach to copying objects:

1. On the tool bar, select Tools>Database copy.

2. Identify source and destination connections with the copy options you would like.

3. For object type, select table(s).

4. Specify the specific table(s) (e.g. table1).

The copy command approach is old and its features are not being updated with the release of new data types. There are a number of more current approaches to this like Oracle's data pump (even for tables).

Numbers have higher precedence than strings so of course the + operators want to convert your strings into numbers before adding.

You could do:

print 'There are ' + CONVERT(varchar(10),@Number) +
      ' alias combinations did not match a record'

or use the (rather limited) formatting facilities of RAISERROR:

RAISERROR('There are %i alias combinations did not match a record',10,1,@Number)
WITH NOWAIT

The problem here are PHP namespaces. You need to learn how to use them. As your controller are in App\Http\Controllers namespace, if you refer any other class, you need to add leading backslash (or proper namespace) or add use statement at the beginning of file (before class definition).

So in your case you could use:

$headquote = \DB::table('quotation_texts')->find(176);
$headquote = \App\Quotation::find(176);

or add in your controller class use statement so the beginning of your controller class could look like this:

<?php

namespace App\Http\Controllers;

use DB;
use App\Quotation;

For more information about namespaces you could look at How to use objects from other namespaces and how to import namespaces in PHP or namespaces in PHP manual

When implementing the onClickListener, you can use v.getContext.startActivity.

btn.setOnClickListener(new OnClickListener() {                  
    @Override
    public void onClick(View v) {
        v.getContext().startActivity(PUT_YOUR_INTENT_HERE);
    }
});

This code was very helpful for me. Maybe it could be for you also

wb.Navigate(url);
while(wb.ReadyState != WebBrowserReadyState.Complete)
{
     Application.DoEvents();
}
MessageBox.Show("Loaded");

std::is_same() is only available since C++11. For pre-C++11 you can use typeid():

template <typename T>
void foo()
{
    if (typeid(T) == typeid(animal)) { /* ... */ }
}

You use this style code

.heighttext{
 float:right;
 height:30px;
 width:70px;
 }

Here and easy Example.

As Charles Duffey has stated, XML parsers are best parsed with a proper XML parsing tools. For one time job the following should work.

grep -oPm1 "(?<=<title>)[^<]+"

The other answers detail the reason for the error. A possible cause (to check) may be your class has a variable and method with the same name, which you then call. Python accesses the variable as a callable - with ().

e.g. Class A defines self.a and self.a():

>>> class A:
...     def __init__(self, val):
...         self.a = val
...     def a(self):
...         return self.a
...
>>> my_a = A(12)
>>> val = my_a.a()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

You need to use

 <?php bloginfo('template_directory'); ?>

It returns the directory of the current WordPress theme.

Now for example, if your theme has some image named example.jpg inside some folder name subfolder folder in the images folder.

 themes
   |-> your theme
          |-> images
                |->subfolder
                      |-> examples.jpg

You access it like this

 <img class="article-image" src="<?php bloginfo('template_directory'); ?> /images/subfolder/example.jpg" border="0" alt="">

If you want to stage and commit all your files on Github do the following;

git add -A                                                                                
git commit -m "commit message"

The new method for dynamic elements is MutationsObserver .. The following example uses underscore.js to use ( _.each ) function.

MutationObserver = window.MutationObserver || window.WebKitMutationObserver || window.MozMutationObserver;    

var observerjQueryPlugins = new MutationObserver(function (repeaterWrapper) {

    _.each(repeaterWrapper, function (repeaterItem, index) {

        var jq_nodes = $(repeaterItem.addedNodes);

        jq_nodes.each(function () {

            // Date Picker
            $(this).parents('.current-repeateritem-container').find('.element-datepicker').datepicker({
                dateFormat: "dd MM, yy",
                showAnim: "slideDown",
                changeMonth: true,
                numberOfMonths: 1
            });

        });

    });

});

observerjQueryPlugins.observe(document, {
    childList: true,
    subtree: true,
    attributes: false,
    characterData: false
});

The approach you should take is to install pip for Python 3.2.

You do this in the following way:

$ curl -O https://bootstrap.pypa.io/get-pip.py
$ sudo python3.2 get-pip.py

Then, you can install things for Python 3.2 with pip-3.2, and install things for Python 2-7 with pip-2.7. The pip command will end up pointing to one of these, but I'm not sure which, so you will have to check.

The Placeholder does not render any tags for itself, so it is great for grouping content without the overhead of outer HTML tags.

The Panel does have outer HTML tags but does have some cool extra properties.

• BackImageUrl: Gets/Sets the background image's URL for the panel

• HorizontalAlign: Gets/Sets the
  horizontal alignment of the parent's contents

• Wrap: Gets/Sets whether the
  panel's content wraps

There is a good article at startvbnet here.

Try DBVis - download at https://www.dbvis.com/download - there is a pro version (not needed) and a open version that should suffice.

All you have to do is to get the right JDBC - database driver for SQL Server, the tool shows tables and references orthogonal, hierarchical, in a circle ;-) etc. just by pressing one single button. I use the free version for years now.

I have the same problem.... I change my project name and i have this problem...my solution was the checking project refences and use / in my web.xml (instead of /*)

There is a round available in the Foundation library (it's actually in Darwin, but Foundation imports Darwin and most of the time you'll want to use Foundation instead of using Darwin directly).

import Foundation

users = round(users)

Running your code in a playground and then calling:

print(round(users))

Outputs:

15.0

round() always rounds up when the decimal place is >= .5 and down when it's < .5 (standard rounding). You can use floor() to force rounding down, and ceil() to force rounding up.

If you need to round to a specific place, then you multiply by pow(10.0, number of places), round, and then divide by pow(10, number of places):

Round to 2 decimal places:

let numberOfPlaces = 2.0
let multiplier = pow(10.0, numberOfPlaces)
let num = 10.12345
let rounded = round(num * multiplier) / multiplier
print(rounded)

Outputs:

10.12

Note: Due to the way floating point math works, rounded may not always be perfectly accurate. It's best to think of it more of an approximation of rounding. If you're doing this for display purposes, it's better to use string formatting to format the number rather than using math to round it.

simply replace

background-image:url(../images/images2.jpg) no-repeat;

with

background:url(../images/images2.jpg)  center;

Found tar -cvf site1-$seqNumber.tar -C /var/www/ site1 as more friendlier solution than tar -cvf site1-$seqNumber.tar -C /var/www/site1 . (notice the . in the second solution) for the following reasons

• Tar file name can be insignificant as the original folder is now an archive entry
• Tar file name being insignificant to the content can now be used for other purposes like sequence numbers, periodical backup etc.

alternatively you can retrieve DOM properties with .prop

here is sample code for select box

if( ctrl.prop('type') == 'select-one' ) { // for single select }

if( ctrl.prop('type') == 'select-multiple' ) { // for multi select }

for textbox

  if( ctrl.prop('type') == 'text' ) { // for text box }

I came across this problem because my cols exceeded the row grid length (> 12)

A solution using 100% Bootstrap 4:

Since the rows in Bootstrap are already display: flex

You just need to add flex-fill to the Col, and h-100 to the container and any children.

Pen here: https://codepen.io/joshkopecek/pen/Exjdgjo

<div class="container-fluid h-100">
  <div class="row justify-content-center h-100">

    <div class="col-4 hidden-md-down flex-fill" id="yellow">
      XXXX
    </div>

    <div id="blue" class="col-10 col-sm-10 col-md-10 col-lg-8 col-xl-8 h-100">
      Form Goes Here
    </div>

    <div id="green" class="col-10 col-sm-10 col-md-10 col-lg-8 col-xl-8 h-100">
      Another form
    </div>
  </div>
</div>

The above answers are all cool. I found it easy to json serialize the object and deserialize as a dictionary.

var json = JsonConvert.SerializeObject(obj);
var dictionary = JsonConvert.DeserializeObject<Dictionary<string, string>>(json);

I don't know how performance is effected but this is much easier to read. You could also wrap it inside a function.

public static Dictionary<string, TValue> ToDictionary<TValue>(object obj)
{       
    var json = JsonConvert.SerializeObject(obj);
    var dictionary = JsonConvert.DeserializeObject<Dictionary<string, TValue>>(json);   
    return dictionary;
}

Use like so:

var obj = new { foo = 12345, boo = true };
var dictionary = ToDictionary<string>(obj);

Save this xml and add as a background for the linear layout....

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
    <stroke android:width="4dp" android:color="#FF00FF00" /> 
    <solid android:color="#ffffff" /> 
    <padding android:left="7dp" android:top="7dp" 
            android:right="7dp" android:bottom="0dp" /> 
    <corners android:radius="4dp" /> 
</shape>

Hope this helps! :)

How can I get the value from the map, which is passed as a reference to a function?

Well, you can pass it as a reference. The standard reference wrapper that is.

typedef std::map<std::string, std::string> MAP;
// create your map reference type
using map_ref_t = std::reference_wrapper<MAP>;

// use it 
void function(map_ref_t map_r)
{
    // get to the map from inside the
    // std::reference_wrapper
    // see the alternatives behind that link
    MAP & the_map = map_r;
    // take the value from the map
    // by reference
    auto & value_r = the_map["key"];
    // change it, "in place"
    value_r = "new!";
}

And the test.

    void test_ref_to_map() {

    MAP valueMap;
    valueMap["key"] = "value";
    // pass it by reference
    function(valueMap);
    // check that the value has changed
    assert( "new!" == valueMap["key"] );
}

I think this is nice and simple. Enjoy ...

this is my solution

JTextField username = new JTextField();
JTextField password = new JPasswordField();
Object[] message = {
    "Username:", username,
    "Password:", password
};

int option = JOptionPane.showConfirmDialog(null, message, "Login", JOptionPane.OK_CANCEL_OPTION);
if (option == JOptionPane.OK_OPTION) {
    if (username.getText().equals("h") && password.getText().equals("h")) {
        System.out.println("Login successful");
    } else {
        System.out.println("login failed");
    }
} else {
    System.out.println("Login canceled");
}

Try this, if enter key was pressed you can capture it like this for example, I developed an answer the other day html button specify selected, see if this helps.

Specify the forms name as for example yourFormName then you should be able to submit the form without having focus on the form.

document.onkeypress = keyPress;

function keyPress(e){
  var x = e || window.event;
  var key = (x.keyCode || x.which);
  if(key == 13 || key == 3){
   //  myFunc1();
   document.yourFormName.submit();
  }
}

Simple to me is like this:

$Time = Get-Date -Format "yyyy-MM-dd HH:mm K"
$Description = "Done on time"

"$Time,$Description"|Add-Content -Path $File # Keep no space between content variables

If you have a lot of columns, then create a variable like $NewRow like:

$Time = Get-Date -Format "yyyy-MM-dd HH:mm K"
$Description = "Done on time"
$NewRow = "$Time,$Description" # No space between variables, just use comma(,).

$NewRow | Add-Content -Path $File # Keep no space between content variables

Please note the difference between Set-Content (overwrites the existing contents) and Add-Content (appends to the existing contents) of the file.

You could use custom css classes (className) instead of the css tag too. No need for an external package.

import React, { useState, useEffect } from 'react';
import { css } from '@emotion/css'

const Hello = (props) => {
    const [loaded, setLoaded] = useState(false);

    useEffect(() => {
        // For load
        setTimeout(function () {
            setLoaded(true);
        }, 50); // Browser needs some time to change to unload state/style

        // For unload
        return () => {
            setLoaded(false);
        };
    }, [props.someTrigger]); // Set your trigger

    return (
        <div
            css={[
                css`
                    opacity: 0;
                    transition: opacity 0s;
                `,
                loaded &&
                    css`
                        transition: opacity 2s;
                        opacity: 1;
                    `,
            ]}
        >
            hello
        </div>
    );
};

This solution will help to calculate the height and width at runtime.

    let messageText = "Your Text String"
    let size = CGSize.init(width: 250, height: 1000)
    let options = NSStringDrawingOptions.usesFontLeading.union(.usesLineFragmentOrigin)
    let estimateFrame = NSString(string: messageText).boundingRect(with:  size, options: options, attributes: [NSAttributedString.Key.font: UIFont(name: "HelveticaNeue", size: 17)!], context: nil)

Here you can calculate the estimated height that your string would take and pass it to the UILabel frame.

estimateFrame.Width
estimateFrame.Height 

I just needed to replace pip with pip3 so I ended up running the command as follows: pip3 install matplotlib

CREDIT: Programmatic access to properties in Spring without re-reading the properties file

I've found a nice implementation of accessing the properties programmatically in spring without reloading the same properties that spring has already loaded. [Also, It is not required to hardcode the property file location in the source]

With these changes, the code looks cleaner & more maintainable.

The concept is pretty simple. Just extend the spring default property placeholder (PropertyPlaceholderConfigurer) and capture the properties it loads in the local variable

public class SpringPropertiesUtil extends PropertyPlaceholderConfigurer {

    private static Map<String, String> propertiesMap;
    // Default as in PropertyPlaceholderConfigurer
    private int springSystemPropertiesMode = SYSTEM_PROPERTIES_MODE_FALLBACK;

    @Override
    public void setSystemPropertiesMode(int systemPropertiesMode) {
        super.setSystemPropertiesMode(systemPropertiesMode);
        springSystemPropertiesMode = systemPropertiesMode;
    }

    @Override
    protected void processProperties(ConfigurableListableBeanFactory beanFactory, Properties props) throws BeansException {
        super.processProperties(beanFactory, props);

        propertiesMap = new HashMap<String, String>();
        for (Object key : props.keySet()) {
            String keyStr = key.toString();
            String valueStr = resolvePlaceholder(keyStr, props, springSystemPropertiesMode);
            propertiesMap.put(keyStr, valueStr);
        }
    }

    public static String getProperty(String name) {
        return propertiesMap.get(name).toString();
    }

}

Usage Example

SpringPropertiesUtil.getProperty("myProperty")

Spring configuration changes

<bean id="placeholderConfigMM" class="SpringPropertiesUtil">
    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
    <property name="locations">
    <list>
        <value>classpath:myproperties.properties</value>
    </list>
    </property>
</bean>

Hope this helps to solve the problems you have

I am just doing this without even trying it. Would this work?

this is the only attrib you need to add to get your code working.

Personally, I would not place too much emphasis on such "folk wisdom." What may have been true in the past might well not be true now. I would assume that all of the operations relating to a web-page's interpretation and rendering are fully asynchronous ("fetching" something and "acting upon it" are two entirely different things that might be being handled by different threads, etc.), and in any case entirely beyond your control or your concern.

I'd put CSS references in the "head" portion of the document, along with any references to external scripts. (Some scripts may demand to be placed in the body, and if so, oblige them.)

Beyond that ... if you observe that "this seems to be faster/slower than that, on this/that browser," treat this observation as an interesting but irrelevant curiosity and don't let it influence your design decisions. Too many things change too fast. (Anyone want to lay any bets on how many minutes it will be before the Firefox team comes out with yet another interim-release of their product? Yup, me neither.)

Finally, I found the solution to my problem.

I looked into the Magento system log file (var/log/system.log). There I saw the exact error.

The error is as below:-

Recoverable Error: Argument 1 passed to Mage_Core_Model_Store::setWebsite() must be an instance of Mage_Core_Model_Website, null given, called in YOUR_PATH\app\code\core\Mage\Core\Model\App.php on line 555 and defined in YOUR_PATH\app\code\core\Mage\Core\Model\Store.php on line 285

Recoverable Error: Argument 1 passed to Mage_Core_Model_Store_Group::setWebsite() must be an instance of Mage_Core_Model_Website, null given, called in YOUR_PATH\app\code\core\Mage\Core\Model\App.php on line 575 and defined in YOUR_PATH\app\code\core\Mage\Core\Model\Store\Group.php on line 227

Actually, I had this error before. But, error display message like Error: 404 Not Found was new to me.

The reason for this error is that store_id and website_id for admin should be set to 0 (zero). But, when you import database to new server, somehow these values are not set to 0.

Open PhpMyAdmin and run the following query in your database:-

SET FOREIGN_KEY_CHECKS=0;
UPDATE `core_store` SET store_id = 0 WHERE code='admin';
UPDATE `core_store_group` SET group_id = 0 WHERE name='Default';
UPDATE `core_website` SET website_id = 0 WHERE code='admin';
UPDATE `customer_group` SET customer_group_id = 0 WHERE customer_group_code='NOT LOGGED IN';
SET FOREIGN_KEY_CHECKS=1;

I have written about this problem and solution over here:-

Magento: Solution to "Error: 404 Not Found" in Admin Login Page

Try adding to td:

display: -webkit-box; // to make td as block
word-break: break-word; // to make content justify

overflowed tds will align with new row.

A Java constructor has the same name as the name of the class to which it belongs.

Constructor’s syntax does not include a return type, since constructors never return a value.

Constructor is always called when object is created. example:- Default constructor

class Student3{  
    int id;  
    String name;  
    void display(){System.out.println(id+" "+name);}  
    public static void main(String args[]){  
        Student3 s1=new Student3();  
        Student3 s2=new Student3();  
        s1.display();  
        s2.display();  
    }  
} 

Output:

0 null
0 null

Explanation: In the above class,you are not creating any constructor so compiler provides you a default constructor.Here 0 and null values are provided by default constructor.

Example of parameterized constructor

In this example, we have created the constructor of Student class that have two parameters. We can have any number of parameters in the constructor.

class Student4{  
    int id;  
    String name;  
    Student4(int i,String n){  
        id = i;  
        name = n;  
    }  
    void display(){System.out.println(id+" "+name);}  
    public static void main(String args[]){  
        Student4 s1 = new Student4(111,"Karan");  
        Student4 s2 = new Student4(222,"Aryan");  
        s1.display();  
        s2.display();  
    }  
}  

Output:

111 Karan
222 Aryan

In general, when you get an error like this, just do

yum provides ld-linux.so.2

then you'll see something like:

glibc-2.20-5.fc21.i686 : The GNU libc libraries
Repo        : fedora
Matched from:
Provides    : ld-linux.so.2

and then you just run the following like BRPocock wrote (in case you were wondering what the logic was...):

yum install glibc.i686

Joakim Backman's answer is specific, but this may bring additional clarity to it.

There is a minor difference. As per SQL For Dummies, 8th Edition (2013):

The DECIMAL data type is similar to NUMERIC. ... The difference is that your implementation may specify a precision greater than what you specify — if so, the implementation uses the greater precision. If you do not specify precision or scale, the implementation uses default values, as it does with the NUMERIC type.

It seems that the difference on some implementations of SQL is in data integrity. DECIMAL allows overflow from what is defined based on some system defaults, where as NUMERIC does not.

As there is no implementation of a variable it can't be abstract ;)

I am late for the party. Try replacing as below, mine worked perfectly- "DOMDocument" to "MSXML2.DOMDocument60" "XMLHTTP" to "MSXML2.XMLHTTP60"

Try to use Virtual Mouse (vmouse) Bindings from jQuery Mobile. It's virtual event especially for your case:

It seems that in recent Pandas versions the way to go is to use df.assign:

df1 = df1.assign(e=np.random.randn(sLength))

It doesn't produce SettingWithCopyWarning.

You can do that by using following code

$('#button_id').on('click', function(){
$('#element_want_to_target').addClass('.animation_class');});

I use fetchObject() here a small example using Symfony 4.4

    <?php 
    use Doctrine\DBAL\Driver\Connection;

    class MyController{

    public function index($username){
      $queryBuilder = $connection->createQueryBuilder();
      $queryBuilder
        ->select('id', 'name')
        ->from('app_user')
        ->where('name = ?')
        ->setParameter(0, $username)
        ->setMaxResults(1);
      $stmUser = $queryBuilder->execute();

      dump($stmUser->fetchObject());

      //get_class_methods($stmUser) -> to see all methods
    }
  }

Response:

{ 
"id": "2", "name":"myuser"
}

For PHPStorm 2020.3.2 on ubuntu inorder to reset expiration license, you should run following commands:

sudo rm ~/.config/JetBrains/PhpStorm2020.3/options/other.xml 
sudo rm ~/.config/JetBrains/PhpStorm2020.3/eval/*          
sudo rm -rf .java/.userPrefs

This can occur on android too not just computers. Was browsing using Kiwi when the site I was on began to endlessly redirect so I cut net access to close it out and noticed my phone had DL'd something f.txt in my downloaded files.

Deleted it and didn't open.

It says that it requires zip extension

laravel/installer v1.4.0 requires ext-zip...

Install using (to install the default version):

sudo apt install php-zip

Or, if you're running a specific version of PHP:

# For php v7.0
sudo apt-get install php7.0-zip

# For php v7.1
sudo apt-get install php7.1-zip

# For php v7.2
sudo apt-get install php7.2-zip

# For php v7.3
sudo apt-get install php7.3-zip

# For php v7.4
sudo apt-get install php7.4-zip

Depending on your needs, you may wish to try the jQuery touch plugin; you can try an example here. It works fine to drag on my iPhone, whereas jQuery UI Draggable doesn't.

Alternatively, you can try this plugin, though that might require you to actually write your own draggable function.

As a sidenote: Believe it or not, we're hearing increasing buzz about how touch devices such as the iPad and iPhone is causing problems both for websites using :hover/onmouseover functions and draggable content.

If you're interested in the underlying solution for this, it's to use three new JavaScript events; ontouchstart, ontouchmove and ontouchend. Apple actually has written an article about their use, which you can find here. A simplified example can be found here. These events are used in both of the plugins I linked to.

Laravel 5 uses .env file to configure your app. .env should not be committed on your repository, like github or bitbucket. On your local environment your .env will look like the following:

# .env
APP_ENV=local

For your production server, you might have the following config:

# .env
APP_ENV=production

I had this problem with an F# project that had been here and there between Visual Studio and MonoDevelop, perhaps originating in the latter (I forget). In VS, the optimize box was unchecked, yet optimization certainly seemed to be occuring as far as the debugger was concerned.

After comparing the XML of the project file against that of a healthy one, the problem was obvious: the healthy project had an explicit <optimize>false</optimize> line, whereas the bad one was missing it completely. VS was obviously inferring from its absence that optimization was disabled, while the compiler was doing the opposite.

The solution was to add this property to the project file, and reload.

Google disallows automated access in their TOS, so if you accept their terms you would break them.

That said, I know of no lawsuit from Google against a scraper. Even Microsoft scraped Google, they powered their search engine Bing with it. They got caught in 2011 red handed :)

There are two options to scrape Google results:

1) Use their API

UPDATE 2020: Google has reprecated previous APIs (again) and has new prices and new limits. Now (https://developers.google.com/custom-search/v1/overview) you can query up to 10k results per day at 1,500 USD per month, more than that is not permitted and the results are not what they display in normal searches.

• You can issue around 40 requests per hour You are limited to what they give you, it's not really useful if you want to track ranking positions or what a real user would see. That's something you are not allowed to gather.

• If you want a higher amount of API requests you need to pay.

• 60 requests per hour cost 2000 USD per year, more queries require a custom deal.

2) Scrape the normal result pages

• Here comes the tricky part. It is possible to scrape the normal result pages. Google does not allow it.
• If you scrape at a rate higher than 8 (updated from 15) keyword requests per hour you risk detection, higher than 10/h (updated from 20) will get you blocked from my experience.
• By using multiple IPs you can up the rate, so with 100 IP addresses you can scrape up to 1000 requests per hour. (24k a day) (updated)
• There is an open source search engine scraper written in PHP at http://scraping.compunect.com It allows to reliable scrape Google, parses the results properly and manages IP addresses, delays, etc. So if you can use PHP it's a nice kickstart, otherwise the code will still be useful to learn how it is done.

3) Alternatively use a scraping service (updated)

• Recently a customer of mine had a huge search engine scraping requirement but it was not 'ongoing', it's more like one huge refresh per month.
  In this case I could not find a self-made solution that's 'economic'.
  I used the service at http://scraping.services instead. They also provide open source code and so far it's running well (several thousand resultpages per hour during the refreshes)
• The downside is that such a service means that your solution is "bound" to one professional supplier, the upside is that it was a lot cheaper than the other options I evaluated (and faster in our case)
• One option to reduce the dependency on one company is to make two approaches at the same time. Using the scraping service as primary source of data and falling back to a proxy based solution like described at 2) when required.

You can zip the list with itself sans the first element:

a = [5, 7, 11, 4, 5]

for previous, current in zip(a, a[1:]):
    print(previous, current)

This works even if your list has no elements or only 1 element (in which case zip returns an empty iterable and the code in the for loop never executes). It doesn't work on generators, only sequences (tuple, list, str, etc).

You have to implement KeyListener,take a look here: http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyListener.html

More details on how to use it: http://docs.oracle.com/javase/tutorial/uiswing/events/keylistener.html

There's actually no direct way to get path to webdir in Symfony2 as the framework is completely independent of the webdir.

You can use getRootDir() on instance of kernel class, just as you write. If you consider renaming /web dir in future, you should make it configurable. For example AsseticBundle has such an option in its DI configuration (see here and here).

Here are my personal, super-condensed notes, as far as this subject pertains to me currently, for anyone who's interested:

• Both PKCS12 and PEM can store entire cert chains: public keys, private keys, and root (CA) certs.
• .pfx == .p12 == "PKCS12"
  • fully encrypted
• .pem == .cer == .cert == "PEM" (or maybe not... could be binary... see comments...)
  • base-64 (string) encoded X509 cert (binary) with a header and footer
    • base-64 is basically just a string of "A-Za-z0-9+/" used to represent 0-63, 6 bits of binary at a time, in sequence, sometimes with 1 or 2 "=" characters at the very end when there are leftovers ("=" being "filler/junk/ignore/throw away" characters)
    • the header and footer is something like "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" or "-----BEGIN ENCRYPTED PRIVATE KEY-----" and "-----END ENCRYPTED PRIVATE KEY-----"
  • Windows recognizes .cer and .cert as cert files
• .jks == "Java Key Store"
  • just a Java-specific file format which the API uses
    • .p12 and .pfx files can also be used with the JKS API
• "Trust Stores" contain public, trusted, root (CA) certs, whereas "Identity/Key Stores" contain private, identity certs; file-wise, however, they are the same.

there are gotchas with this - but ultimately the simplest way will be to use

string s = [yourlongstring];
string[] values = s.Split(',');

If the number of commas and entries isn't important, and you want to get rid of 'empty' values then you can use

string[] values = s.Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

One thing, though - this will keep any whitespace before and after your strings. You could use a bit of Linq magic to solve that:

string[] values = s.Split(',').Select(sValue => sValue.Trim()).ToArray();

That's if you're using .Net 3.5 and you have the using System.Linq declaration at the top of your source file.

To expand on what @JoshuaMaddox said, in the MDN Learning Area, under the "Introduction to HTML" section, the Document and website structure sub-section says (bold/emphasis is by me):

Header

Usually a big strip across the top with a big heading and/or logo. This is where the main common information about a website usually stays from one webpage to another.

Navigation bar

Links to the site's main sections; usually represented by menu buttons, links, or tabs. Like the header, this content usually remains consistent from one webpage to another — having an inconsistent navigation on your website will just lead to confused, frustrated users. Many web designers consider the navigation bar to be part of the header rather than a individual component, but that's not a requirement; in fact some also argue that having the two separate is better for accessibility, as screen readers can read the two features better if they are separate.

An angular-only solution that works alongside ng-click is possible by using compile to wrap the ng-click expression.

Directive:

.directive('confirmClick', function ($window) {
  var i = 0;
  return {
    restrict: 'A',
    priority:  1,
    compile: function (tElem, tAttrs) {
      var fn = '$$confirmClick' + i++,
          _ngClick = tAttrs.ngClick;
      tAttrs.ngClick = fn + '($event)';

      return function (scope, elem, attrs) {
        var confirmMsg = attrs.confirmClick || 'Are you sure?';

        scope[fn] = function (event) {
          if($window.confirm(confirmMsg)) {
            scope.$eval(_ngClick, {$event: event});
          }
        };
      };
    }
  };
});

HTML:

<a ng-click="doSomething()" confirm-click="Are you sure you wish to proceed?"></a>

If you use bash, then the terminal history is saved in a file called .bash_history. Delete it, and history will be gone.

However, for MySQL the better approach is not to enter the password in the command line. If you just specify the -p option, without a value, then you will be prompted for the password and it won't be logged.

Another option, if you don't want to enter your password every time, is to store it in a my.cnf file. Create a file named ~/.my.cnf with something like:

[client]
user = <username>
password = <password>

Make sure to change the file permissions so that only you can read the file.

Of course, this way your password is still saved in a plaintext file in your home directory, just like it was previously saved in .bash_history.

As I know, there is no direct support, but you can use plain-ol' javascript for that:

// Cookies
function createCookie(name, value, days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        var expires = "; expires=" + date.toGMTString();
    }
    else var expires = "";               

    document.cookie = name + "=" + value + expires + "; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1, c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
    }
    return null;
}

function eraseCookie(name) {
    createCookie(name, "", -1);
}

GL

(Angular 2 - Angular 7)

Component can be declared in a single module only. In order to use a component from another module, you need to do two simple tasks:

1. Export the component in the other module
2. Import the other module, into the current module

1st Module:

Have a component (lets call it: "ImportantCopmonent"), we want to re-use in the 2nd Module's page.

@NgModule({
declarations: [
    FirstPage,
    ImportantCopmonent // <-- Enable using the component html tag in current module
],
imports: [
  IonicPageModule.forChild(NotImportantPage),
  TranslateModule.forChild(),
],
exports: [
    FirstPage,
    ImportantCopmonent // <--- Enable using the component in other modules
  ]
})
export class FirstPageModule { }

2nd Module:

Reuses the "ImportantCopmonent", by importing the FirstPageModule

@NgModule({
declarations: [
    SecondPage,
    Example2ndComponent,
    Example3rdComponent
],
imports: [
  IonicPageModule.forChild(SecondPage),
  TranslateModule.forChild(),
  FirstPageModule // <--- this Imports the source module, with its exports
], 
exports: [
    SecondPage,
]
})
export class SecondPageModule { }

Of all the approaches, I find using org.apache.commons.collections.CollectionUtils#isEqualCollection is the best approach. Here are the reasons -

• I don't have to declare any additional list/set myself
• I am not mutating the input lists
• It's very efficient. It checks the equality in O(N) complexity.

If it's not possible to have apache.commons.collections as a dependency, I would recommend to implement the algorithm it follows to check equality of the list because of it's efficiency.

Remove the public keyword from int[] locations={1,2,3};. An access modifier isn't allowed inside a method, as its accessbility is defined by its method scope.

If your goal is to use this reference in many a method, you might want to move the declaration outside the method.

// works also after bind operation for WINDOWS

DWORD timeout = timeout_in_seconds * 1000;
setsockopt(socket, SOL_SOCKET, SO_RCVTIMEO, (const char*)&timeout, sizeof timeout);

Since the question is general enough that it might attract people looking for answers to very trivial cases: if you just want a child rather than a descendant, you can use Linq:

private void ItemsControlItem_Loaded(object sender, RoutedEventArgs e)
{
    if (SomeCondition())
    {
        var children = (sender as Panel).Children;
        var child = (from Control child in children
                 where child.Name == "NameTextBox"
                 select child).First();
        child.Focus();
    }
}

or of course the obvious for loop iterating over Children.

rootLayout.findFocus().clearFocus();

This is nowhere definied in the JDBC API contract, but if you're lucky, the JDBC driver in question may return the complete SQL by just calling PreparedStatement#toString(). I.e.

System.out.println(preparedStatement);

To my experience, the ones which do so are at least the PostgreSQL 8.x and MySQL 5.x JDBC drivers. For the case your JDBC driver doesn't support it, your best bet is using a statement wrapper which logs all setXxx() methods and finally populates a SQL string on toString() based on the logged information. For example Log4jdbc or P6Spy.

Your code (which looks ok) doesn't return a pointer to an array. It returns a pointer to the first element of an array.

In fact that's usually what you want to do. Most manipulation of arrays are done via pointers to individual elements, not via pointers to the array as a whole.

You can define a pointer to an array, for example this:

double (*p)[42];

defines p as a pointer to a 42-element array of doubles. A big problem with that is that you have to specify the number of elements in the array as part of the type -- and that number has to be a compile-time constant. Most programs that deal with arrays need to deal with arrays of varying sizes; a given array's size won't vary after it's been created, but its initial size isn't necessarily known at compile time, and different array objects can have different sizes.

A pointer to the first element of an array lets you use either pointer arithmetic or the indexing operator [] to traverse the elements of the array. But the pointer doesn't tell you how many elements the array has; you generally have to keep track of that yourself.

If a function needs to create an array and return a pointer to its first element, you have to manage the storage for that array yourself, in one of several ways. You can have the caller pass in a pointer to (the first element of) an array object, probably along with another argument specifying its size -- which means the caller has to know how big the array needs to be. Or the function can return a pointer to (the first element of) a static array defined inside the function -- which means the size of the array is fixed, and the same array will be clobbered by a second call to the function. Or the function can allocate the array on the heap -- which makes the caller responsible for deallocating it later.

Everything I've written so far is common to C and C++, and in fact it's much more in the style of C than C++. Section 6 of the comp.lang.c FAQ discusses the behavior of arrays and pointers in C.

But if you're writing in C++, you're probably better off using C++ idioms. For example, the C++ standard library provides a number of headers defining container classes such as <vector> and <array>, which will take care of most of this stuff for you. Unless you have a particular reason to use raw arrays and pointers, you're probably better off just using C++ containers instead.

EDIT : I think you edited your question as I was typing this answer. The new code at the end of your question is, as you observer, no good; it returns a pointer to an object that ceases to exist as soon as the function returns. I think I've covered the alternatives.

With jooR it's merely:

on(obj).call(methodName /*params*/).get()

Here is a more elaborate example:

public class TestClass {

    public int add(int a, int b) { return a + b; }
    private int mul(int a, int b) { return a * b; }
    static int sub(int a, int b) { return a - b; }

}

import static org.joor.Reflect.*;

public class JoorTest {

    public static void main(String[] args) {
        int add = on(new TestClass()).call("add", 1, 2).get(); // public
        int mul = on(new TestClass()).call("mul", 3, 4).get(); // private
        int sub = on(TestClass.class).call("sub", 6, 5).get(); // static
        System.out.println(add + ", " + mul + ", " + sub);
    }
}

This prints:

3, 12, 1

If the question isn't just "how to access an integer form of the timedelta?" but "how to convert the timedelta column in the dataframe to an int?" the answer might be a little different. In addition to the .dt.days accessor you need either df.astype or pd.to_numeric

Either of these options should help:

df['tdColumn'] = pd.to_numeric(df['tdColumn'].dt.days, downcast='integer')

or

df['tdColumn'] = df['tdColumn'].dt.days.astype('int16')

table
{ 
margin-left: auto;
margin-right: auto;
}

This will definitely work. Cheers

Put this formula in cell d31 and copy down to d39

 =iferror(vlookup(b31,$f$3:$g$12,2,0),"")

Here's what is going on. VLOOKUP:

• Takes a value (here the contents of b31),
• Looks for it in the first column of a range (f3:f12 in the range f3:g12), and
• Returns the value for the corresponding row in a column in that range (in this case, the 2nd column or g3:g12 of the range f3:g12).

As you know, the last argument of VLOOKUP sets the match type, with FALSE or 0 indicating an exact match.

Finally, IFERROR handles the #N/A when VLOOKUP does not find a match.

As your question confirms, they are different: & is ONLY string concatenation, + is overloaded with both normal addition and concatenation.

In your example:

• because one of the operands to + is an integer VB attempts to convert the string to a integer, and as your string is not numeric it throws; and

• & only works with strings so the integer is converted to a string.

let viewDemo = UIView()
viewDemo.frame = CGRect(x: 50, y: 50, width: 50, height: 50)
self.view.addSubview(viewDemo)

string::npos is a constant (probably -1) representing a non-position. It's returned by method find when the pattern was not found.

<input type="image" src="path to image" name="submit" />

UPDATE:

For button states, you can use type="submit" and then add a class to it

<input type="submit" name="submit" class="states" />

Then in css, use background images for:

.states{
background-image:url(path to url);
height:...;
width:...;
}

.states:hover{
background-position:...;
}

.states:active{
background-position:...;
}

Your understanding is mostly correct. You use select_related when the object that you're going to be selecting is a single object, so OneToOneField or a ForeignKey. You use prefetch_related when you're going to get a "set" of things, so ManyToManyFields as you stated or reverse ForeignKeys. Just to clarify what I mean by "reverse ForeignKeys" here's an example:

class ModelA(models.Model):
    pass

class ModelB(models.Model):
    a = ForeignKey(ModelA)

ModelB.objects.select_related('a').all() # Forward ForeignKey relationship
ModelA.objects.prefetch_related('modelb_set').all() # Reverse ForeignKey relationship

The difference is that select_related does an SQL join and therefore gets the results back as part of the table from the SQL server. prefetch_related on the other hand executes another query and therefore reduces the redundant columns in the original object (ModelA in the above example). You may use prefetch_related for anything that you can use select_related for.

The tradeoffs are that prefetch_related has to create and send a list of IDs to select back to the server, this can take a while. I'm not sure if there's a nice way of doing this in a transaction, but my understanding is that Django always just sends a list and says SELECT ... WHERE pk IN (...,...,...) basically. In this case if the prefetched data is sparse (let's say U.S. State objects linked to people's addresses) this can be very good, however if it's closer to one-to-one, this can waste a lot of communications. If in doubt, try both and see which performs better.

Everything discussed above is basically about the communications with the database. On the Python side however prefetch_related has the extra benefit that a single object is used to represent each object in the database. With select_related duplicate objects will be created in Python for each "parent" object. Since objects in Python have a decent bit of memory overhead this can also be a consideration.

This solution doesn't require an import:

tuple(map(lambda x, y: x + y, tuple1, tuple2))

The problem is that C++ is a statically-typed language, meaning that if something is declared as a string, it's a string, and if something is declared as a double, it's a double. Unlike other languages like JavaScript or PHP, there is no way to automatically convert from a string to a numeric value because the conversion might not be well-defined. For example, if you try converting the string "Hi there!" to a double, there's no meaningful conversion. Sure, you could just set the double to 0.0 or NaN, but this would almost certainly be masking the fact that there's a problem in the code.

To fix this, don't buffer the file contents into a string. Instead, just read directly into the double:

double lol;
openfile >> lol;

This reads the value directly as a real number, and if an error occurs will cause the stream's .fail() method to return true. For example:

double lol;
openfile >> lol;

if (openfile.fail()) {
    cout << "Couldn't read a double from the file." << endl;
}

I prefer @Ista solution, cause needs no extra package and is simple.
A modification of the data.table solution also solve my problem, and is more general.
My data.frame is

> str(df)
'data.frame':   579 obs. of  11 variables:
 $ trees     : num  2000 5000 1000 2000 1000 1000 2000 5000 5000 1000 ...

 $ shrinkage : num  0.01 0.001 0.01 0.005 0.01 0.01 0.001 0.005 0.005 0.001     ...

The data.table solution needs order on i to do the job:

> require(data.table)
> dt1 <- data.table(df)
> dt2 = dt1[order(-efet, G1, G2), head(.SD, 3), by = .(G1, G2)]

By some reason, it does not order the way pointed (probably because ordering by the groups). So, another ordering is done.

You can query the all_tab_columns view in the database.

SELECT  table_name, column_name, data_type, data_length FROM all_tab_columns where table_name = 'CUSTOMER'

I wasnt satisfied with the answers here and on other questions. The highest rated answer doesn't take padding or border into account, and therefore obviously ignores box-sizing as well. My answer combines some techniques here and and on other threads to get a solution that works to my satisfaction.

It isnt perfect: When no numerical value was able to be retrieved for the line-height (e.g. normal or inherit), it just uses the font-size multiplied by 1.2. Perhaps someone else can suggest a reliable way to detect the pixel value in those cases.

Other than that, it has been able to correctly handle most of the styles and cases I have thrown at it.

For those who don't care about IE6/IE7, the same guy who wrote Raphael built an svg engine specifically for modern browsers: Snap.svg .. they have a really nice site with good docs: http://snapsvg.io

snap.svg couldn't be easier to use right out of the box and can manipulate/update existing SVGs or generate new ones. You can read this stuff on the snap.io about page but here's a quick run down:

Cons

• To make use of snap's features you must forgo on support for older browsers. Raphael supports browsers like IE6/IE7, snap features are only supported by IE9 and up, Safari, Chrome, Firefox, and Opera.

Pros

• Implements the full features of SVG like masking, clipping, patterns, full gradients, groups, and more.

• Ability to work with existing SVGs: content does not have to be generated with Snap for it to work with Snap, allowing you to create the content with any common design tools.

• Full animation support using a straightforward, easy-to-implement JavaScript API

• Works with strings of SVGs (for example, SVG files loaded via Ajax) without having to actually render them first, similar to a resource container or sprite sheet.

check it out if you're interested: http://snapsvg.io

Official(?) instructions: http://peak.telecommunity.com/DevCenter/EasyInstall#uninstalling-packages

If you have replaced a package with another version, then you can just delete the package(s) you don't need by deleting the PackageName-versioninfo.egg file or directory (found in the installation directory).

If you want to delete the currently installed version of a package (or all versions of a package), you should first run:

easy_install -mxN PackageName

This will ensure that Python doesn't continue to search for a package you're planning to remove. After you've done this, you can safely delete the .egg files or directories, along with any scripts you wish to remove.

There are nice answers here, and i agree with @Austin Greco (the second option with separate components)
There is another way i like, currying.
What you can do is create a function that accept a parameter (your parameter) and returns another function that accepts another parameter (the click event in this case). then you are free to do with it what ever you want.

ES5:

handleChange(param) { // param is the argument you passed to the function
    return function (e) { // e is the event object that returned

    };
}

ES6:

handleChange = param => e => {
    // param is the argument you passed to the function
    // e is the event object that returned
};

And you will use it this way:

<input 
    type="text" 
    onChange={this.handleChange(someParam)} 
/>

Here is a full example of such usage:

const someArr = ["A", "B", "C", "D"];_x000D_
_x000D_
class App extends React.Component {_x000D_
  state = {_x000D_
    valueA: "",_x000D_
    valueB: "some initial value",_x000D_
    valueC: "",_x000D_
    valueD: "blah blah"_x000D_
  };_x000D_
_x000D_
  handleChange = param => e => {_x000D_
    const nextValue = e.target.value;_x000D_
    this.setState({ ["value" + param]: nextValue });_x000D_
  };_x000D_
_x000D_
  render() {_x000D_
    return (_x000D_
      <div>_x000D_
        {someArr.map(obj => {_x000D_
          return (_x000D_
            <div>_x000D_
              <label>_x000D_
                {`input ${obj}   `}_x000D_
              </label>_x000D_
              <input_x000D_
                type="text"_x000D_
                value={this.state["value" + obj]}_x000D_
                onChange={this.handleChange(obj)}_x000D_
              />_x000D_
              <br />_x000D_
              <br />_x000D_
            </div>_x000D_
          );_x000D_
        })}_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
}_x000D_
_x000D_
const rootElement = document.getElementById("root");_x000D_
ReactDOM.render(<App />, rootElement);

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>_x000D_
<div id="root"></div>

Note that this approach doesn't solve the creation of a new instance on each render.
I like this approach over the other inline handlers as this one is more concise and readable in my opinion.

Edit:
As suggested in the comments below, you can cache / memoize the result of the function.

Here is a naive implementation:

let memo = {};_x000D_
_x000D_
const someArr = ["A", "B", "C", "D"];_x000D_
_x000D_
class App extends React.Component {_x000D_
  state = {_x000D_
    valueA: "",_x000D_
    valueB: "some initial value",_x000D_
    valueC: "",_x000D_
    valueD: "blah blah"_x000D_
  };_x000D_
_x000D_
  handleChange = param => {_x000D_
    const handler = e => {_x000D_
      const nextValue = e.target.value;_x000D_
      this.setState({ ["value" + param]: nextValue });_x000D_
    }_x000D_
    if (!memo[param]) {_x000D_
      memo[param] = e => handler(e)_x000D_
    }_x000D_
    return memo[param]_x000D_
  };_x000D_
_x000D_
  render() {_x000D_
    return (_x000D_
      <div>_x000D_
        {someArr.map(obj => {_x000D_
          return (_x000D_
            <div key={obj}>_x000D_
              <label>_x000D_
                {`input ${obj}   `}_x000D_
              </label>_x000D_
              <input_x000D_
                type="text"_x000D_
                value={this.state["value" + obj]}_x000D_
                onChange={this.handleChange(obj)}_x000D_
              />_x000D_
              <br />_x000D_
              <br />_x000D_

          );_x000D_
        })}_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
}_x000D_
_x000D_
const rootElement = document.getElementById("root");_x000D_
ReactDOM.render(<App />, rootElement);

You can use .delay() before an animation, like this:

$("#myElem").show().delay(5000).fadeOut();

If it's not an animation, use setTimeout() directly, like this:

$("#myElem").show();
setTimeout(function() { $("#myElem").hide(); }, 5000);

You do the second because .hide() wouldn't normally be on the animation (fx) queue without a duration, it's just an instant effect.

Or, another option is to use .delay() and .queue() yourself, like this:

$("#myElem").show().delay(5000).queue(function(n) {
  $(this).hide(); n();
});

I use brew and the prefix was already set to be:

$ npm config get prefix
/Users/[user]/.node

I did notice that the bin and lib folder were owned by root, which prevented the usual non sudo install, so I re-owned them to the user

$ cd /Users/[user]/.node
$ chown -R [user]:[group] lib
$ chown -R [user]:[group] bin

Then I just added the path to my .bash_profile which is located at /Users/[user]

PATH=$PATH:~/.node/bin

Instead of having a fat APK file, I would like to use just the armeabi files and remove the armeabi-v7a folder.

The opposite is a much better strategy. If you have minSdkVersion to 14 and upload your apk to the play store, you'll notice you'll support the same number of devices whether you support armeabi or not. Therefore, there are no devices with Android 4 or higher which would benefit from armeabi at all.

This is probably why the Android NDK doesn't even support armeabi anymore as per revision r17b. [source]

I like simple javascript, and I usually have jQuery around. Here's what I came up with, based off mparkuk's:

Here's a demo: http://codepen.io/erikpukinskis/pen/EjaaMY?editors=101

Step 1: Install update http://httpjunkie.com/2013/340/develop-mvc-5-with-asp-net-identity-in-visual-studio-2012/.

So I have a step 2: http://httpjunkie.com/2013/340/develop-mvc-5-with-asp-net-identity-in-visual-studio-2012/

If you follow that tutorial on my website I follow it up with a full install of Foundation 5 and a cool Hybrid OffCanvas/Top-Bar navigation.
