I would use a mysqli connection to connect to the database. Here is an example:

$connection = new mysqli("127.0.0.1", "username", "password", "database_name", 3306);

The next step is to select the information. In your case I would do:

$query = $connection->query("SELECT `names` FROM `Customers`;");

And finally we make an array from all these names by typing:

$array = Array();
while($result = $query->fetch_assoc()){
    $array[] = $result['names'];
}

print_r($array);

So what I've done in this code: I selected all names from the table using a mysql query. Next I use a while loop to check if the $query has a next value. If so the while loop continues and adds that value to the array '$array'. Else the loop stops. And finally I print the array using the 'print_r' method so you can see it all works. I hope this was helpful.

use sep='\s*,\s*' so that you will take care of spaces in column-names:

transactions = pd.read_csv('transactions.csv', sep=r'\s*,\s*',
                           header=0, encoding='ascii', engine='python')

alternatively you can make sure that you don't have unquoted spaces in your CSV file and use your command (unchanged)

prove:

print(transactions.columns.tolist())

Output:

['product_id', 'customer_id', 'store_id', 'promotion_id', 'month_of_year', 'quarter', 'the_year', 'store_sales', 'store_cost', 'unit_sales', 'fact_count']

Here is what made the error disappear for me:

Close eclipse, open up a terminal window and run:

$ mvn clean eclipse:clean eclipse:eclipse

Are you using Maven? If so,

1. Right-click on the project, Build Path and go to Configure Build Path
2. Click the libraries tab. If Maven dependencies are not in the list, you need to add it.
3. Close the dialog.

To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.

And then clean

Edit 1:

If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.

Edit 2:

You can also try going into the folder where you have all your projects and delete the .metadata for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.

Here is an Array Prototype function:

Array.prototype.unique = function() {
    var unique = [];
    for (var i = 0; i < this.length; i++) {
        if (unique.indexOf(this[i]) == -1) {
            unique.push(this[i]);
        }
    }
    return unique;
};

Not saying your mapping is correct or wrong but I think hibernate wants a instance of the set where you declare the field.

@OneToMany(cascade=CascadeType.ALL, fetch = FetchType.EAGER)
//@ElementCollection(targetClass=Role.class)
@Column(name = "ROLE_ID")
private Set<Role> roles = new HashSet<Role>();

[this answer is a bit dated: read the edits]

Say hello to your friends: map and filter and reduce and forEach and every etc.

(I only occasionally write for-loops in javascript, because of block-level scoping is missing, so you have to use a function as the body of the loop anyway if you need to capture or clone your iteration index or value. For-loops are more efficient generally, but sometimes you need a closure.)

The most readable way:

[....].filter(x => x==2).length

(We could have written .filter(function(x){return x==2}).length instead)

The following is more space-efficient (O(1) rather than O(N)), but I'm not sure how much of a benefit/penalty you might pay in terms of time (not more than a constant factor since you visit each element exactly once):

[....].reduce((total,x) => (x==2 ? total+1 : total), 0)

(If you need to optimize this particular piece of code, a for loop might be faster on some browsers... you can test things on jsperf.com.)

You can then be elegant and turn it into a prototype function:

[1, 2, 3, 5, 2, 8, 9, 2].count(2)

Like this:

Object.defineProperties(Array.prototype, {
    count: {
        value: function(value) {
            return this.filter(x => x==value).length;
        }
    }
});

You can also stick the regular old for-loop technique (see other answers) inside the above property definition (again, that would likely be much faster).

2017 edit:

Whoops, this answer has gotten more popular than the correct answer. Actually, just use the accepted answer. While this answer may be cute, the js compilers probably don't (or can't due to spec) optimize such cases. So you should really write a simple for loop:

Object.defineProperties(Array.prototype, {
    count: {
        value: function(query) {
            /* 
               Counts number of occurrences of query in array, an integer >= 0 
               Uses the javascript == notion of equality.
            */
            var count = 0;
            for(let i=0; i<this.length; i++)
                if (this[i]==query)
                    count++;
            return count;
        }
    }
});

You could define a version .countStrictEq(...) which used the === notion of equality. The notion of equality may be important to what you're doing! (for example [1,10,3,'10'].count(10)==2, because numbers like '4'==4 in javascript... hence calling it .countEq or .countNonstrict stresses it uses the == operator.)

Also consider using your own multiset data structure (e.g. like python's 'collections.Counter') to avoid having to do the counting in the first place.

class Multiset extends Map {
    constructor(...args) {
        super(...args);
    }
    add(elem) {
        if (!this.has(elem))
            this.set(elem, 1);
        else
            this.set(elem, this.get(elem)+1);
    }
    remove(elem) {
        var count = this.has(elem) ? this.get(elem) : 0;
        if (count>1) {
            this.set(elem, count-1);
        } else if (count==1) {
            this.delete(elem);
        } else if (count==0)
            throw `tried to remove element ${elem} of type ${typeof elem} from Multiset, but does not exist in Multiset (count is 0 and cannot go negative)`;
            // alternatively do nothing {}
    }
}

Demo:

> counts = new Multiset([['a',1],['b',3]])
Map(2) {"a" => 1, "b" => 3}

> counts.add('c')
> counts
Map(3) {"a" => 1, "b" => 3, "c" => 1}

> counts.remove('a')
> counts
Map(2) {"b" => 3, "c" => 1}

> counts.remove('a')
Uncaught tried to remove element a of type string from Multiset, but does not exist in Multiset (count is 0 and cannot go negative)

sidenote: Though, if you still wanted the functional-programming way (or a throwaway one-liner without overriding Array.prototype), you could write it more tersely nowadays as [...].filter(x => x==2).length. If you care about performance, note that while this is asymptotically the same performance as the for-loop (O(N) time), it may require O(N) extra memory (instead of O(1) memory) because it will almost certainly generate an intermediate array and then count the elements of that intermediate array.

Try this. This will work. $('#baba').prop('selectedIndex',0);

If somebody is looking for solution respecting holidays (without any huge library like pandas), try this function:

import holidays
import datetime


def previous_working_day(check_day_, holidays=holidays.US()):
    offset = max(1, (check_day_.weekday() + 6) % 7 - 3)
    most_recent = check_day_ - datetime.timedelta(offset)
    if most_recent not in holidays:
        return most_recent
    else:
        return previous_working_day(most_recent, holidays)

check_day = datetime.date(2020, 12, 28)
previous_working_day(check_day)

which produce:

datetime.date(2020, 12, 24)

You should use the new format specifications to define how your value should be represented:

>>> from math import pi  # pi ~ 3.141592653589793
>>> '{0:.2f}'.format(pi)
'3.14'

The documentation can be a bit obtuse at times, so I recommend the following, easier readable references:

• the Python String Format Cookbook: shows examples of the new-style .format() string formatting
• pyformat.info: compares the old-style % string formatting with the new-style .format() string formatting

Python 3.6 introduced literal string interpolation (also known as f-strings) so now you can write the above even more succinct as:

>>> f'{pi:.2f}'
'3.14'

  g2val = 0

    For i = 3 To 18

     If g1val > Cells(33, i).Value Then
        g1val = g1val
    Else
       g1val = Cells(33, i).Value
     End If

    Next i

    For j = 32 To 57
        If g2val > Cells(31, j).Value Then
           g2val = g2val
        Else

SWIFT 5

If you don't have a ViewController set as the initial ViewController in storyboard, you need to do 2 things:

1. Go to your project TARGETS, select your project -> General -> Clear the Main Interface field.
2. Always inside project TARGETS, now go to Info -> Application Scene Manifest -> Scene Configuration -> Application Session Role -> Item0 (Default Configuration) -> delete the storyboard name field.

Finally, you can now add your code in SceneDelegate:

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
    // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
    // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
    guard let windowScene = (scene as? UIWindowScene) else { return }

    window = UIWindow(windowScene: windowScene)


    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    // Make sure you set an Storyboard ID for the view controller you want to instantiate
    window?.rootViewController = storyboard.instantiateViewController(withIdentifier: identifier)
    window?.makeKeyAndVisible()

}

Here is one way to do this using css

It will also be empty if the new Referrer Policy standard draft is used to prevent that the referer header is sent to the request origin. Example:

<meta name="referrer" content="none">

Although Chrome and Firefox have already implemented a draft version of the Referrer Policy, you should be careful with it because for example Chrome expects no-referrer instead of none (and I have seen also never somewhere).

To flip bits (i.e. 1's complement/invert) you can do the following:

Since value ExORed with all 1s results into inversion, for a given bit width you can use ExOR to invert them.

In Binary
a=1010 --> this is 0xA or decimal 10
then 
c = 1111 ^ a = 0101 --> this is 0xF or decimal 15
-----------------
In Python
a=10
b=15
c = a ^ b --> 0101
print(bin(c)) # gives '0b101'

You need to read and write document.cookie

if (document.cookie.indexOf("visited=") >= 0) {
  // They've been here before.
  alert("hello again");
}
else {
  // set a new cookie
  expiry = new Date();
  expiry.setTime(expiry.getTime()+(10*60*1000)); // Ten minutes

  // Date()'s toGMTSting() method will format the date correctly for a cookie
  document.cookie = "visited=yes; expires=" + expiry.toGMTString();
  alert("this is your first time");
}

Some examples:

• Bit operations for example converting to and from Base64 (which is 6 bits instead of 8)
• doing power of 2 operations (1 << 4 equal to 2^4 i.e. 16)
• Writing more readable code when working with bits. For example, defining constants using 1 << 4 or 1 << 5 is more readable.

1. I configured hadoop.tmp.dir in conf/core-site.xml

2. I configured dfs.data.dir in conf/hdfs-site.xml

3. I configured dfs.name.dir in conf/hdfs-site.xml

4. Deleted everything under "/tmp/hadoop-/" directory

5. Changed file permissions from 777 to 755 for directory listed under dfs.data.dir

   And the data node started working.

Dan Benjamin's Hivelogic article Installing Ruby, RubyGems, and Rails on Snow Leopard is the recommended place to go although the article is for 1.8, so here's a Ruby 1.9-specific install on Snow Leopard. Watch out for the 64-bit thing... either go all 64-bit 'fat' (as is - for example - Apache on OS X, which can cause problems with 32-bit libraries) or check any gems you're likely to use to make sure they're okay for 64-bit.

Here is a Solution for Jupyter and Python3:

I droped my images in a folder named ImageTest. My directory is:

C:\Users\MyPcName\ImageTest\image.png

To show the image I used this expression:

![title](/notebooks/ImageTest/image.png "ShowMyImage")

Also watch out for / and \

if it's Oracle you would use the "all_views" table.

It really depends on your dbms.

Is it legal? Yes, changing your location on Android is legal. Likewise, you can change VPN settings in Microsoft Edge on your PC, and all this is within the law. VPN allows you to change your IP address, safeguarding your privacy and protecting your actual location from being exposed. However, VPN laws may vary from country to country. There are restrictions in some regions.

Brief summary: Yes, you can change your region on Android and a VPN is a necessary assistant for this. It's simple, safe and legal. Today, VPN is the best way to change the region and unblock sites with regional restrictions.

Though this does not directly answer the question, but I think it is a good alternative to avoid the question altogether.

To avoid all the autoload_paths or eager_load_paths hassle, create a "lib" or a "misc" directory under "app" directory. Place codes as you would normally do in there, and Rails will load files just like how it will load (and reload) model files.

As others have mentioned, the "is" keyword. However, if you're going to later cast it to that type, eg.

TForm t = (TForm)c;

Then you should use the "as" keyword.

e.g. TForm t = c as TForm.

Then you can check

if(t != null)
{
 // put TForm specific stuff here
}

Don't combine as with is because it's a duplicate check.

I know this was an old answer, but i would like to share my simple solution.

Pretty late to the party, but here's my two cents:

Use a LinkedHashSet

I assume what you need is a collection which:

• disallows you to insert duplicates;
• retains insertion order.

LinkedHashSet does this. The advantage over using an ArrayList is that LinkedHashSet has a complexity of O(1) for the contains operation, as opposed to ArrayList, which has O(n).

^{Of course, you need to implement your object's equals and hashCode methods properly.}

Tried to install lxml, grab and other extensions, which requires VS 10.0+ and get the same issue. I find own way to solve this problem(Windows 10 x64, Python 3.4+):

1. Install Visual C++ 2010 Express (download). (Do not install Microsoft Visual Studio 2010 Service Pack 1 )

2. Remove all the Microsoft Visual C++ 2010 Redistributable packages from Control Panel\Programs and Features. If you don't do those then the install is going to fail with an obscure "Fatal error during installation" error.

3. Install offline version of Windows SDK for Visual Studio 2010 (v7.1) (download). This is required for 64bit extensions. Windows has builtin mounting for ISOs. Just mount the ISO and run Setup\SDKSetup.exe instead of setup.exe.

4. Create a vcvars64.bat file in C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64 that contains:

   CALL "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd" /x64

5. Find extension on this site, then put them into the python folder, and install .whl extension with pip:

   python -m pip install extensionname.whl

No need of JQuery simply you can do

if(yourObject['email']){
 // what if this property exists.
}

as with any value for email will return you true, if there is no such property or that property value is null or undefined will result to false

If you mean lists, try ==:

l1 = [1,2,3]
l2 = [1,2,3,4]

l1 == l2 # False

If you mean array:

l1 = array('l', [1, 2, 3])
l2 = array('d', [1.0, 2.0, 3.0])
l1 == l2 # True
l2 = array('d', [1.0, 2.0, 3.0, 4.0])
l1 == l2 # False

If you want to compare strings (per your comment):

date_string  = u'Thu Sep 16 13:14:15 CDT 2010'
date_string2 = u'Thu Sep 16 14:14:15 CDT 2010'
date_string == date_string2 # False

Assuming a forward-compatible context in OpenGL 3 and up, you can either use glPolygonMode as mentioned before, but note that lines with thickness more than 1px are now deprecated. So while you can draw triangles as wire-frame, they need to be very thin. In OpenGL ES, you can use GL_LINES with the same limitation.

In OpenGL it is possible to use geometry shaders to take incoming triangles, disassemble them and send them for rasterization as quads (pairs of triangles really) emulating thick lines. Pretty simple, really, except that geometry shaders are notorious for poor performance scaling.

What you can do instead, and what will also work in OpenGL ES is to employ fragment shader. Think of applying a texture of wire-frame triangle to the triangle. Except that no texture is needed, it can be generated procedurally. But enough talk, let's code. Fragment shader:

in vec3 v_barycentric; // barycentric coordinate inside the triangle
uniform float f_thickness; // thickness of the rendered lines

void main()
{
    float f_closest_edge = min(v_barycentric.x,
        min(v_barycentric.y, v_barycentric.z)); // see to which edge this pixel is the closest
    float f_width = fwidth(f_closest_edge); // calculate derivative (divide f_thickness by this to have the line width constant in screen-space)
    float f_alpha = smoothstep(f_thickness, f_thickness + f_width, f_closest_edge); // calculate alpha
    gl_FragColor = vec4(vec3(.0), f_alpha);
}

And vertex shader:

in vec4 v_pos; // position of the vertices
in vec3 v_bc; // barycentric coordinate inside the triangle

out vec3 v_barycentric; // barycentric coordinate inside the triangle

uniform mat4 t_mvp; // modeview-projection matrix

void main()
{
    gl_Position = t_mvp * v_pos;
    v_barycentric = v_bc; // just pass it on
}

Here, the barycentric coordinates are simply (1, 0, 0), (0, 1, 0) and (0, 0, 1) for the three triangle vertices (the order does not really matter, which makes packing into triangle strips potentially easier).

The obvious disadvantage of this approach is that it will eat some texture coordinates and you need to modify your vertex array. Could be solved with a very simple geometry shader but I'd still suspect it will be slower than just feeding the GPU with more data.

Code completion. It helps a lot with exploring code.

I find Geany (http://geany.uvena.de/) quite good.

The best way around this would be to create an Excel called 'launcher.xlsm' in the same folder as the file you wish to open. In the 'launcher' file put the following code in the 'Workbook' object, but set the constant TargetWBName to be the name of the file you wish to open.

Private Const TargetWBName As String = "myworkbook.xlsx"

'// First, a function to tell us if the workbook is already open...
Function WorkbookOpen(WorkBookName As String) As Boolean
' returns TRUE if the workbook is open
    WorkbookOpen = False
    On Error GoTo WorkBookNotOpen
    If Len(Application.Workbooks(WorkBookName).Name) > 0 Then
        WorkbookOpen = True
        Exit Function
    End If
WorkBookNotOpen:
End Function

Private Sub Workbook_Open()
    'Check if our target workbook is open
    If WorkbookOpen(TargetWBName) = False Then
        'set calculation to manual
        Application.Calculation = xlCalculationManual
        Workbooks.Open ThisWorkbook.Path & "\" & TargetWBName
        DoEvents
        Me.Close False
    End If
End Sub

Set the constant 'TargetWBName' to be the name of the workbook that you wish to open. This code will simply switch calculation to manual, then open the file. The launcher file will then automatically close itself. *NOTE: If you do not wish to be prompted to 'Enable Content' every time you open this file (depending on your security settings) you should temporarily remove the 'me.close' to prevent it from closing itself, save the file and set it to be trusted, and then re-enable the 'me.close' call before saving again. Alternatively, you could just set the False to True after Me.Close

Analog of the @synchronized directive from Objective-C can have an arbitrary return type and nice rethrows behaviour in Swift.

// Swift 3
func synchronized<T>(_ lock: AnyObject, _ body: () throws -> T) rethrows -> T {
    objc_sync_enter(lock)
    defer { objc_sync_exit(lock) }
    return try body()
}

The use of the defer statement lets directly return a value without introducing a temporary variable.

In Swift 2 add the @noescape attribute to the closure to allow more optimisations:

// Swift 2
func synchronized<T>(lock: AnyObject, @noescape _ body: () throws -> T) rethrows -> T {
    objc_sync_enter(lock)
    defer { objc_sync_exit(lock) }
    return try body()
}

Based on the answers from GNewc [1] (where I like arbitrary return type) and Tod Cunningham [2] (where I like defer).

You can effectively remove scientific notation in printing with this code:

options(scipen=999)

concurency: multiple execution flows with the potential to share resources

Ex: two threads competing for a I/O port.

paralelism: splitting a problem in multiple similar chunks.

Ex: parsing a big file by running two processes on every half of the file.

Try withColumn with the function when as follows:

val sqlContext = new SQLContext(sc)
import sqlContext.implicits._ // for `toDF` and $""
import org.apache.spark.sql.functions._ // for `when`

val df = sc.parallelize(Seq((4, "blah", 2), (2, "", 3), (56, "foo", 3), (100, null, 5)))
    .toDF("A", "B", "C")

val newDf = df.withColumn("D", when($"B".isNull or $"B" === "", 0).otherwise(1))

newDf.show() shows

+---+----+---+---+
|  A|   B|  C|  D|
+---+----+---+---+
|  4|blah|  2|  1|
|  2|    |  3|  0|
| 56| foo|  3|  1|
|100|null|  5|  0|
+---+----+---+---+

I added the (100, null, 5) row for testing the isNull case.

I tried this code with Spark 1.6.0 but as commented in the code of when, it works on the versions after 1.4.0.

I have found Adobe Dreamweaver to be quite good at that. However, it's not free.

Your arguments are in the wrong order. The connection comes first according to the docs

<?php
require("constants.php");

// 1. Create a database connection
$connection = mysqli_connect(DB_SERVER,DB_USER,DB_PASS);

if (!$connection) {
    error_log("Failed to connect to MySQL: " . mysqli_error($connection));
    die('Internal server error');
}

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    error_log("Database selection failed: " . mysqli_error($connection));
    die('Internal server error');
}

?>

You can access any LayoutParams from code using View.getLayoutParams. You just have to be very aware of what LayoutParams your accessing. This is normally achieved by checking the containing ViewGroup if it has a LayoutParams inner child then that's the one you should use. In your case it's RelativeLayout.LayoutParams. You'll be using RelativeLayout.LayoutParams#addRule(int verb) and RelativeLayout.LayoutParams#addRule(int verb, int anchor)

You can get to it via code:

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)button.getLayoutParams();
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
params.addRule(RelativeLayout.LEFT_OF, R.id.id_to_be_left_of);

button.setLayoutParams(params); //causes layout update

super() & this()

• super() - to call parent class constructor.
• this() - to call same class constructor.

NOTE:

• We can use super() and this() only in constructor not anywhere else, any attempt to do so will lead to compile-time error.

• We have to keep either super() or this() as the first line of the constructor but NOT both simultaneously.

super & this keyword

• super - to call parent class members(variables and methods).
• this - to call same class members(variables and methods).

NOTE: We can use both of them anywhere in a class except static areas(static block or method), any attempt to do so will lead to compile-time error.

The linked comment is incorrect : 'L' to '1' will produce a rising edge.

In addition, if your clock signal transitions from 'H' to '1', rising_edge(clk) will (correctly) not trigger while (clk'event and clk = '1') (incorrectly) will.

Granted, that may look like a contrived example, but I have seen clock waveforms do that in real hardware, due to failures elsewhere.

Since you are using Visual Studio 11 Beta, you will want to use the latest and greatest. The new Web API contains classes for this.

Here is what I did to get a data set that included both the total and the number that met the criteria, within each shipping container. That let me answer the question "How many shipping containers have more than X% items over size 51"

select
   Schedule,
   PackageNum,
   COUNT (UniqueID) as Total,
   SUM (
   case
      when
         Size > 51 
      then
         1 
      else
         0 
   end
) as NumOverSize

@imanuo answers is already great, but if you are working with an application full of number, you can consider an extension like this:

extension String {

    init(withInt int: Int, leadingZeros: Int = 2) {
        self.init(format: "%0\(leadingZeros)d", int)
    }

    func leadingZeros(_ zeros: Int) -> String {
        if let int = Int(self) {
            return String(withInt: int, leadingZeros: zeros)
        }
        print("Warning: \(self) is not an Int")
        return ""
    }
    
}

In this way you can call wherever:

String(withInt: 3) 
// prints 03

String(withInt: 23, leadingZeros: 4) 
// prints 0023

"42".leadingZeros(2)
// prints 42

"54".leadingZeros(3)
// prints 054

Try this. This solution is a bit risky. There are no checks. The string must only have hex values and the string length must match the return type size. But no need for extra headers.

char hextob(char ch)
{
    if (ch >= '0' && ch <= '9') return ch - '0';
    if (ch >= 'A' && ch <= 'F') return ch - 'A' + 10;
    if (ch >= 'a' && ch <= 'f') return ch - 'a' + 10;
    return 0;
}
template<typename T>
T hextot(char* hex)
{
    T value = 0;
    for (size_t i = 0; i < sizeof(T)*2; ++i)
        value |= hextob(hex[i]) << (8*sizeof(T)-4*(i+1));
    return value;
};

Usage:

int main()
{
    char str[4] = {'f','f','f','f'};
    std::cout << hextot<int16_t>(str)  << "\n";
}

Note: the length of the string must be divisible by 2

You have to check which Python you are using. I had the same problem because the Python I was using was not the same one that brew was using. In your command line:

1. which python
   output: /usr/bin/python
2. which brew
   output: /usr/local/bin/brew     //so they are different
3. cd /usr/local/lib/python2.7/site-packages
4. ls   //you can see PyQt4 and sip are here
5. Now you need to add usr/local/lib/python2.7/site-packages to your python path.
6. open ~/.bash_profile   //you will open your bash_profile file in your editor
7. Add 'export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH' to your bash file and save it
8. Close your terminal and restart it to reload the shell
9. python
10. import PyQt4    // it is ok now

You need to use an undocumented trick with Excel's LINEST function:

=LINEST(known_y's, [known_x's], [const], [stats])

Background

A regular linear regression is calculated (with your data) as:

=LINEST(B2:B21,A2:A21)

which returns a single value, the linear slope (m) according to the formula:

which for your data:

is:

Undocumented trick Number 1

You can also use Excel to calculate a regression with a formula that uses an exponent for x different from 1, e.g. x^1.2:

using the formula:

=LINEST(B2:B21, A2:A21^1.2)

which for you data:

is:

You're not limited to one exponent

Excel's LINEST function can also calculate multiple regressions, with different exponents on x at the same time, e.g.:

=LINEST(B2:B21,A2:A21^{1,2})

Note: if locale is set to European (decimal symbol ","), then comma should be replaced by semicolon and backslash, i.e. =LINEST(B2:B21;A2:A21^{1\2})

Now Excel will calculate regressions using both x¹ and x² at the same time:

How to actually do it

The impossibly tricky part there's no obvious way to see the other regression values. In order to do that you need to:

• select the cell that contains your formula:

  

• extend the selection the left 2 spaces (you need the select to be at least 3 cells wide):

  

• press F2

• press Ctrl+Shift+Enter

  

You will now see your 3 regression constants:

  y = -0.01777539x^2 + 6.864151123x + -591.3531443

Bonus Chatter

I had a function that I wanted to perform a regression using some exponent:

y = m×x^k + b

But I didn't know the exponent. So I changed the LINEST function to use a cell reference instead:

=LINEST(B2:B21,A2:A21^F3, true, true)

With Excel then outputting full stats (the 4th paramter to LINEST):

I tell the Solver to maximize R²:

And it can figure out the best exponent. Which for you data:

is:

private Camera openFrontFacingCameraGingerbread() {
    int cameraCount = 0;
    Camera cam = null;
    Camera.CameraInfo cameraInfo = new Camera.CameraInfo();
    cameraCount = Camera.getNumberOfCameras();
    for (int camIdx = 0; camIdx < cameraCount; camIdx++) {
        Camera.getCameraInfo(camIdx, cameraInfo);
        if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
            try {
                cam = Camera.open(camIdx);
            } catch (RuntimeException e) {
                Log.e(TAG, "Camera failed to open: " + e.getLocalizedMessage());
            }
        }
    }

    return cam;
}

Add the following permissions in the AndroidManifest.xml file:

<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" android:required="false" />
<uses-feature android:name="android.hardware.camera.front" android:required="false" />

Note: This feature is available in Gingerbread(2.3) and Up Android Version.

Scala solution:

def mnemonics(phoneNum: String, dict: IndexedSeq[String]): Iterable[String] = {
  def mnemonics(d: Int, prefix: String): Seq[String] = {
    if (d >= phoneNum.length) {
      Seq(prefix)
    } else {
      for {
        ch <- dict(phoneNum.charAt(d).asDigit)
        num <- mnemonics(d + 1, s"$prefix$ch")
      } yield num
    }
  }

  mnemonics(0, "")
}

Assuming each digit maps to at most 4 characters, the number of recursive calls T satisfy the inequality T(n) <= 4T(n-1), which is of the order 4^n.

If you wish to have a relatively pain-free experience you can also have a look at the Apache Commons IO package, more specifically the FileUtils class.

Never forget to check third-party libraries. Joda-Time for date manipulation, Apache Commons Lang StringUtils for common string operations and such can make your code more readable.

Java is a great language, but the standard library is sometimes a bit low-level. Powerful, but low-level nonetheless.

To use the class ActionBarOverlayLayout you need to include this in the dependencies section of build.gradle file:

compile 'com.android.support:design:24.1.1'

Sync the project once again and then you will find no problem

As all html ids are unique in a valid html document why not search for the ID directly? If you're concerned if they type in an id that isn't a table then you can inspect the tag type that way?

Just an idea!

I think from Python 2.7.9 and higher pip comes pre installed and it will be in your scripts folder.

So you have to add the "scripts" folder to the path. Mine is installed in C:\Python27\Scripts. Check yours to see what your path is so that you can alter the below accordingly. Then go to PowerShell, paste the below code in PowerShell and hit Enter key. After that, reboot and your issue will be resolved.

[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27\Scripts", "User")

The dot(.) signifies a class name while the hash (#) signifies an element with a specific id attribute. The class will apply to any element decorated with that particular class, while the # style will only apply to the element with that particular id.

Class name:

<style>
   .class { ... }
</style>

<div class="class"></div>
<span class="class></span>
<a href="..." class="class">...</a>

Named element:

<style>
   #name { ... }
</style>

<div id="name"></div>

In case for xml attribute its android:checkedButton which takes the id of the RadioButton to be checked.

<RadioGroup
...
...
android:checkedButton="@+id/IdOfTheRadioButtonInsideThatTobeChecked"
... >....</RadioGroup>

I couldn't find the file in C:\Program Files\Java\jdk1.8.0_261\jre\bin. My sqldeveloper came without jre at all so what it worked for me was copying the file from an older Oracle jre release to C:\Program Files\Java\jdk1.8.0_261\jre\bin.

If you just want to update the relative path you can also do

window.location.pathname = '/relative-link'

"http://domain.com" -> "http://domain.com/relative-link"

You could pass in the command-line option -v with a variable name (v) and a value (=) of the environment variable ("${v}"):

% awk -vv="${v}" 'BEGIN { print v }'
123test

Or to make it clearer (with far fewer vs):

% environment_variable=123test
% awk -vawk_variable="${environment_variable}" 'BEGIN { print awk_variable }'
123test

It's important that your THEAD not be empty in table.As dataTable requires you to specify the number of columns of the expected data . As per your data it should be

<table id="datatable">
    <thead>
        <tr>
            <th>Subscriber ID</th>
            <th>Install Location</th>
            <th>Subscriber Name</th>
            <th>some data</th>
        </tr>
    </thead>
</table>

You can use plain javascript, this will call your_func once, after 5 seconds:

setTimeout(function() { your_func(); }, 5000);

If your function has no parameters and no explicit receiver you can call directly setTimeout(func, 5000)

There is also a plugin I've used once. It has oneTime and everyTime methods.

• jQuery timers plugin

Consider using a subquery:

from p in context.ParentTable 
let cCount =
(
  from c in context.ChildTable
  where p.ParentId == c.ChildParentId
  select c
).Count()
select new { ParentId = p.Key, Count = cCount } ;

If the query types are connected by an association, this simplifies to:

from p in context.ParentTable 
let cCount = p.Children.Count()
select new { ParentId = p.Key, Count = cCount } ;

A simple way is to pass the data attribute to your HTML tag.

Example:

<div data-id='tagid' class="clickElem"></div>

<script>
$(document).on("click",".appDetails", function () {
   var clickedBtnID = $(this).attr('data');
   alert('you clicked on button #' + clickedBtnID);
});
</script>

Any time you need to separate allocation from initialization, you'll need placement new and explicit calling of the destructor manually. Today, it's rarely necessary, since we have the standard containers, but if you have to implement some new sort of container, you'll need it.

For a more generic answer, convert the error value to hex, then lookup the hex value at Windows Task Scheduler Error and Success Constants

The data contained therein will not be parsed as XML, and as such does not need to be valid XML or can contain elements that may appear to be XML but are not.

You can also use the good old micro clearfix for this.

#container::before, #container::after{
    content: ' ';
    display: table;
}

The accepted answer by Josh David Miller works great if you are trying to dynamically add a directive that uses an inline template. However if your directive takes advantage of templateUrl his answer will not work. Here is what worked for me:

.directive('helperModal', [, "$compile", "$timeout", function ($compile, $timeout) {
    return {
        restrict: 'E',
        replace: true,
        scope: {}, 
        templateUrl: "app/views/modal.html",
        link: function (scope, element, attrs) {
            scope.modalTitle = attrs.modaltitle;
            scope.modalContentDirective = attrs.modalcontentdirective;
        },
        controller: function ($scope, $element, $attrs) {
            if ($attrs.modalcontentdirective != undefined && $attrs.modalcontentdirective != '') {
                var el = $compile($attrs.modalcontentdirective)($scope);
                $timeout(function () {
                    $scope.$digest();
                    $element.find('.modal-body').append(el);
                }, 0);
            }
        }
    }
}]);

How about std::remove() instead:

#include <algorithm>
...
vec.erase(std::remove(vec.begin(), vec.end(), 8), vec.end());

This combination is also known as the erase-remove idiom.

You can now use Lambda Layers for this matters. Simply add a layer containing the package you need and it will run perfectly.

It turned out that my problem was that I was using a load balancer to handle the SSL, which then sent it over http to the actual server, which then complained.

Description of a fix is here: http://blog.hackedbrain.com/2006/09/26/how-to-ssl-passthrough-with-wcf-or-transportwithmessagecredential-over-plain-http/

Edit: I fixed my problem, which was slightly different, after talking to microsoft support.

My silverlight app had its endpoint address in code going over https to the load balancer. The load balancer then changed the endpoint address to http and to point to the actual server that it was going to. So on each server's web config I added a listenUri for the endpoint that was http instead of https

<endpoint address="" listenUri="http://[LOAD_BALANCER_ADDRESS]" ... />

lets put this in a simple term. An element is a set of opening and closing tags in use.

Element

<h1>...</h1>

Tag H1 opening tag

<h1>

I discovered this after a lot of experimentation.

In the initialisation of your activity:

setOnLongClickListener(new View.OnLongClickListener() {
  public boolean onLongClick(View view) {
    activity.openContextMenu(view);  
    return true;  // avoid extra click events
  }
});
setOnTouch(new View.OnTouchListener(){
  public boolean onTouch(View v, MotionEvent e){
    switch(e.getAction & MotionEvent.ACTION_MASK){
      // do drag/gesture processing. 
    }
    // you MUST return false for ACTION_DOWN and ACTION_UP, for long click to work
    // you can return true for ACTION_MOVEs that you consume. 
    // DOWN/UP are needed by the long click timer.
    // if you want, you can consume the UP if you have made a drag - so that after 
    // a long drag, no long-click is generated.
    return false;
  }
});
setLongClickable(true);

HTML Pencil is an online HTML editor created for modern browsers.

Typora generates Table of Content by adding [TOC] to your document.

Old answers. An update: use flexbox, pretty much works in all browsers now.

<div style="display: flex; justify-content: flex-end">_x000D_
  <div>I'm on the right</div>_x000D_
</div>

And you can get even fancier, simply:

<div style="display: flex; justify-content: space-around">_x000D_
  <div>Left</div>_x000D_
  <div>Right</div>_x000D_
</div>

And fancier:

<div style="display: flex; justify-content: space-around">_x000D_
   <div>Left</div>_x000D_
   <div>Middle</div>_x000D_
  <div>Right</div>_x000D_
</div>

For a start, you shouldn't have both font-awesome.css and font-awesome.min.css

Generally, use font-awesome.css during development, then switch to font-awesome.min.css once you're happy with the site.

Problems like this are often caused by relative paths and locations, so check where your html file is in relation to the css.

If your html file is in the base directory, and the css in a subfolder off the root, you would need: href="./css/font-awesome.css" (single period)

Change

Morison_File << t;                                 //Printing to file
Morison_File << F;

To

Morison_File << t << ";" << F << endl;                                 //Printing to file

a , would also do instead of ;

Assuming you're passing in strings rather than integers, try casting the arguments to integers:

def example(arg1, arg2, arg3):
     if int(arg1) == 1 and int(arg2) == 2 and int(arg3) == 3:
          print("Example Text")

(Edited to emphasize I'm not asking for clarification; I was trying to be diplomatic in my answer. )

Not sure that it matters which database

UNION and UNION ALL should work on all SQL Servers.

You should avoid of unnecessary UNIONs they are huge performance leak. As a rule of thumb use UNION ALL if you are not sure which to use.

If you have @oneToOne mapping set to FetchType.LAZY and you use second query (because you need Department objects to be loaded as part of Employee objects) what Hibernate will do is, it will issue queries to fetch Department objects for every individual Employee object it fetches from DB.

Later, in the code you might access Department objects via Employee to Department single-valued association and Hibernate will not issue any query to fetch Department object for the given Employee.

Remember, Hibernate still issues queries equal to the number of Employees it has fetched. Hibernate will issue same number of queries in both above queries, if you wish to access Department objects of all Employee objects

I know you asked about GCD, but if you wanted, NSOperationQueue also handles this sort of stuff really gracefully, e.g.:

NSOperationQueue *queue = [[NSOperationQueue alloc] init];

NSOperation *completionOperation = [NSBlockOperation blockOperationWithBlock:^{
    NSLog(@"Starting 3");
}];

NSOperation *operation;

operation = [NSBlockOperation blockOperationWithBlock:^{
    NSLog(@"Starting 1");
    sleep(7);
    NSLog(@"Finishing 1");
}];

[completionOperation addDependency:operation];
[queue addOperation:operation];

operation = [NSBlockOperation blockOperationWithBlock:^{
    NSLog(@"Starting 2");
    sleep(5);
    NSLog(@"Finishing 2");
}];

[completionOperation addDependency:operation];
[queue addOperation:operation];

[queue addOperation:completionOperation];

I had this same problem. For me, it was due to Cache-Control header being set at the server level in IIS to no-cache, no-store. So for my application I had to add in the below to my web.config:

<httpProtocol>
    <customHeaders>
        <remove name="Cache-Control" />
    </customHeaders>
</httpProtocol>

A simple

echo "Y Y N N Y N Y Y N" | ./your_script

This allow you to pass any sequence of "Y" or "N" to your script.

You can do some thing like this,

Initialize with empty array and assign the values later

String importRt = "23:43 43:34";
if(null != importRt) {
            importArray = Arrays.stream(importRt.split(" "))
                    .map(String::trim)
                    .toArray(String[]::new);
        }

System.out.println(Arrays.toString(exportImportArray));

Hope it helps..

This is a very partial answer to your question, but I hope still useful.

Microsoft SQL Server 2008 implements two features that are extremely useful for managing hierarchical data:

• the HierarchyId data type.
• common table expressions, using the with keyword.

Have a look at "Model Your Data Hierarchies With SQL Server 2008" by Kent Tegels on MSDN for starts. See also my own question: Recursive same-table query in SQL Server 2008

Try:

$('#mydiv').find('.myclass');

JS Fiddle demo.

Or:

$('.myclass','#mydiv');

JS Fiddle demo.

Or:

$('#mydiv .myclass');

JS Fiddle demo.

References:

• find().
• Selector context.

Good to learn from the find() documentation:

The .find() and .children() methods are similar, except that the latter only travels a single level down the DOM tree.

Date.strptime(updated,"%a, %d %m %Y %H:%M:%S %Z")

Should be:

Date.strptime(updated, '%a, %d %b %Y %H:%M:%S %Z')

If you add an AssemblyInfo class to your project and amend the AssemblyVersion attribute to end with an asterisk, for example:

[assembly: AssemblyVersion("2.10.*")]

Visual studio will increment the final number for you according to these rules (thanks galets, I had that completely wrong!)

To reference this version in code, so you can display it to the user, you use reflection. For example,

Version version = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version;
DateTime buildDate = new DateTime(2000, 1, 1)
                        .AddDays(version.Build).AddSeconds(version.Revision * 2);
string displayableVersion = $"{version} ({buildDate})";

Three important gotchas that you should know

From @ashes999:

It's also worth noting that if both AssemblyVersion and AssemblyFileVersion are specified, you won't see this on your .exe.

From @BrainSlugs83:

Setting only the 4th number to be * can be bad, as the version won't always increment. The 3rd number is the number of days since the year 2000, and the 4th number is the number of seconds since midnight (divided by 2) [IT IS NOT RANDOM]. So if you built the solution late in a day one day, and early in a day the next day, the later build would have an earlier version number. I recommend always using X.Y.* instead of X.Y.Z.* because your version number will ALWAYS increase this way.

Newer versions of Visual Studio give this error:

(this thread begun in 2009)

The specified version string contains wildcards, which are not compatible with determinism. Either remove wildcards from the version string, or disable determinism for this compilation.

See this SO answer which explains how to remove determinism (https://stackoverflow.com/a/58101474/1555612)

Pandas will start looking from where your current python file is located. Therefore you can move from your current directory to where your data is located with '..' For example:

pd.read_csv('../../../data_folder/data.csv')

Will go 3 levels up and then into a data_folder (assuming it's there) Or

pd.read_csv('data_folder/data.csv')

assuming your data_folder is in the same directory as your .py file.

You can use references in a change migration. This is valid Rails 3.2.13 code:

class AddUserToTester < ActiveRecord::Migration
  def change
    change_table :testers do |t|
      t.references :user, index: true 
    end
  end
  def down
    change_table :testers do |t|
      t.remove :user_id
    end
  end
end

Add

session_start();

Don't forget to remove the space you have before

Easy way to Check

if TextField.stringValue.isEmpty {

}

Updated answer

A better way of doing this is:

import subprocess
import sys

reqs = subprocess.check_output([sys.executable, '-m', 'pip', 'freeze'])
installed_packages = [r.decode().split('==')[0] for r in reqs.split()]

The result:

print(installed_packages)

[
    "Django",
    "six",
    "requests",
]

Check if requests is installed:

if 'requests' in installed_packages:
    # Do something

Why this way? Sometimes you have app name collisions. Importing from the app namespace doesn't give you the full picture of what's installed on the system.

Note, that proposed solution works:

• When using pip to install from PyPI or from any other alternative source (like pip install http://some.site/package-name.zip or any other archive type).
• When installing manually using python setup.py install.
• When installing from system repositories, like sudo apt install python-requests.

Cases when it might not work:

• When installing in development mode, like python setup.py develop.
• When installing in development mode, like pip install -e /path/to/package/source/.

Old answer

A better way of doing this is:

import pip
installed_packages = pip.get_installed_distributions()

For pip>=10.x use:

from pip._internal.utils.misc import get_installed_distributions

Why this way? Sometimes you have app name collisions. Importing from the app namespace doesn't give you the full picture of what's installed on the system.

As a result, you get a list of pkg_resources.Distribution objects. See the following as an example:

print installed_packages
[
    "Django 1.6.4 (/path-to-your-env/lib/python2.7/site-packages)",
    "six 1.6.1 (/path-to-your-env/lib/python2.7/site-packages)",
    "requests 2.5.0 (/path-to-your-env/lib/python2.7/site-packages)",
]

Make a list of it:

flat_installed_packages = [package.project_name for package in installed_packages]

[
    "Django",
    "six",
    "requests",
]

Check if requests is installed:

if 'requests' in flat_installed_packages:
    # Do something

You can use attachEvent(ie8) and addEventListener instead

addEvent(window, 'load', function(){ some_methods_1() });
addEvent(window, 'load', function(){ some_methods_2() });

function addEvent(element, eventName, fn) {
    if (element.addEventListener)
        element.addEventListener(eventName, fn, false);
    else if (element.attachEvent)
        element.attachEvent('on' + eventName, fn);
}

To do this without the leading space, why not:

wc -l < file.txt | bc

Yes, it is sufficient. The way injection type attacks work, is by somehow getting an interpreter (The database) to evaluate something, that should have been data, as if it was code. This is only possible if you mix code and data in the same medium (Eg. when you construct a query as a string).

Parameterised queries work by sending the code and the data separately, so it would never be possible to find a hole in that.

You can still be vulnerable to other injection-type attacks though. For example, if you use the data in a HTML-page, you could be subject to XSS type attacks.

Parent container has to have this:

Open command prompt and locate your adb.exe(it will be in your android-sdk/platform-tools)

adb logcat -d > <path-where-you-want-to-save-file>/filename.txt

If you omit path, it will save logcat in current working directory

The -d option indicates that you are dumping the current contents and then exiting. Prefer notepad++ to open this file so that you can get everything in a proper readable format.

from traceback import format_exc


try:
    fault = 10/0
except ZeroDivision:
    print(format_exc())

Another possibility is to use the format_exc() method from the traceback module.

I assume bash is running on a vt100-compatible terminal in which the user did not explicitly turn off the support for formatting.

First, turn on support for special characters in echo, using -e option. Later, use ansi escape sequence ESC[1m, like:

echo -e "\033[1mSome Text"

More on ansi escape sequences for example here: ascii-table.com/ansi-escape-sequences-vt-100.php

I know this question has been answered, but I would like to share an alternate solution:

Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
String shareSubText = "WhatsApp - The Great Chat App";
String shareBodyText = "https://play.google.com/store/apps/details?id=com.whatsapp&hl=en";
shareIntent.putExtra(Intent.EXTRA_SUBJECT, shareSubText);
shareIntent.putExtra(Intent.EXTRA_TEXT, shareBodyText);
startActivity(Intent.createChooser(shareIntent, "Share With"));

Use the Distinct operator:

var idList = yourList.Select(x=> x.ID).Distinct();

In Yii2 you can do:

use yii\helpers\Url;
$withoutLg = Url::current(['lg'=>null], true);

int[] listOfItems = new[] { 4, 2, 3, 1, 6, 4, 3 };

var duplicates = listOfItems

Here's an example of how you'd use filter within your AngularJS JavaScript (rather than in an HTML element).

In this example, we have an array of Country records, each containing a name and a 3-character ISO code.

We want to write a function which will search through this list for a record which matches a specific 3-character code.

Here's how we'd do it without using filter:

$scope.FindCountryByCode = function (CountryCode) {
    //  Search through an array of Country records for one containing a particular 3-character country-code.
    //  Returns either a record, or NULL, if the country couldn't be found.
    for (var i = 0; i < $scope.CountryList.length; i++) {
        if ($scope.CountryList[i].IsoAlpha3 == CountryCode) {
            return $scope.CountryList[i];
        };
    };
    return null;
};

Yup, nothing wrong with that.

But here's how the same function would look, using filter:

$scope.FindCountryByCode = function (CountryCode) {
    //  Search through an array of Country records for one containing a particular 3-character country-code.
    //  Returns either a record, or NULL, if the country couldn't be found.

    var matches = $scope.CountryList.filter(function (el) { return el.IsoAlpha3 == CountryCode; })

    //  If 'filter' didn't find any matching records, its result will be an array of 0 records.
    if (matches.length == 0)
        return null;

    //  Otherwise, it should've found just one matching record
    return matches[0];
};

Much neater.

Remember that filter returns an array as a result (a list of matching records), so in this example, we'll either want to return 1 record, or NULL.

Hope this helps.

For future reference to anyone here having difficulty, if you are adding the checkboxes dynamically, the correct accepted answer above will not work. You'll need to leverage event delegation which allows a parent node to capture bubbled events from a specific descendant and issue a callback.

// $(<parent>).on('<event>', '<child>', callback);
$(document).on('change', '.checkbox', function() {
    if(this.checked) {
      // checkbox is checked
    }
});

Note that it's almost always unnecessary to use document for the parent selector. Instead choose a more specific parent node to prevent propagating the event up too many levels.

The example below displays how the events of dynamically added dom nodes do not trigger previously defined listeners.

$postList = $('#post-list');_x000D_
_x000D_
$postList.find('h1').on('click', onH1Clicked);_x000D_
_x000D_
function onH1Clicked() {_x000D_
  alert($(this).text());_x000D_
}_x000D_
_x000D_
// simulate added content_x000D_
var title = 2;_x000D_
_x000D_

  $postList.append('<article class="post"><h1>Title ' + title + '</h1></article>');_x000D_
}_x000D_
_x000D_
setTimeout(generateRandomArticle.bind(null, ++title), 1000);_x000D_
setTimeout(generateRandomArticle.bind(null, ++title), 5000);_x000D_
setTimeout(generateRandomArticle.bind(null, ++title), 10000);

  <article class="post">_x000D_
    <h1>Title 2</h1>_x000D_

While this example displays the usage of event delegation to capture events for a specific node (h1 in this case), and issue a callback for such events.

$postList = $('#post-list');_x000D_
_x000D_
$postList.on('click', 'h1', onH1Clicked);_x000D_

You can use the Contains() extension method:

list.Where(r => listofIds.Contains(r.Id))

For a hyperlink just use www.facebook.com/++page ID++/like

Eg: www.facebook.com/MYPAGEISAWESOME/like

To make it work with m.facebook.com here's what you do:

Open the Facebook page you're looking for then change the URL to the mobile URL ( which is www.m.facebook.com/MYPAGEISAWESOME ).

Now you should see a big version of the mobile Facebook page. Copy the target URL of the like button.

Pop that URL into the QR generator to make a "scan to like" barcode. This will open the m.Facebook page in the browser of most mobiles directly from the QR reader. If they are not logged into Facebook then they will be prompted to log in and then click 'like'. If logged in, it will auto like.

Hope this helps!

Also, definitely include something with a "click here/scan here to like us on Facebook"

<wbr> and &shy;

Today you can use both.

<wbr> use to break and do not put more information.

Example, use to show links:

 https://stackoverflow.com/questions/226464/soft-hyphen-in-html-wbr-vs-shy

&shy; when necessary, at this point the text will break and add a hyphen.

Example:

"É im&shy;pos&shy;sí&shy;vel pa&shy;ra um ho&shy;mem a&shy;pren&shy;der a&shy;qui&shy;lo que ele acha que já sa&shy;be."

Did you try du -ks | awk '{print $1*1024}'. That might just work.

The simplest solution is to select the second cell, and press =. This will begin the fomula creation process. Now either type in the 1st cell reference (eg, A1) or click on the first cell and press enter. This should make the second cell reference the value of the first cell.

TL;DR

Summary; if you have binary (non-alphanumeric) data (or a significantly sized payload) to transmit, use multipart/form-data. Otherwise, use application/x-www-form-urlencoded.

The MIME types you mention are the two Content-Type headers for HTTP POST requests that user-agents (browsers) must support. The purpose of both of those types of requests is to send a list of name/value pairs to the server. Depending on the type and amount of data being transmitted, one of the methods will be more efficient than the other. To understand why, you have to look at what each is doing under the covers.

For application/x-www-form-urlencoded, the body of the HTTP message sent to the server is essentially one giant query string -- name/value pairs are separated by the ampersand (&), and names are separated from values by the equals symbol (=). An example of this would be: 

MyVariableOne=ValueOne&MyVariableTwo=ValueTwo

According to the specification:

[Reserved and] non-alphanumeric characters are replaced by `%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character

That means that for each non-alphanumeric byte that exists in one of our values, it's going to take three bytes to represent it. For large binary files, tripling the payload is going to be highly inefficient.

That's where multipart/form-data comes in. With this method of transmitting name/value pairs, each pair is represented as a "part" in a MIME message (as described by other answers). Parts are separated by a particular string boundary (chosen specifically so that this boundary string does not occur in any of the "value" payloads). Each part has its own set of MIME headers like Content-Type, and particularly Content-Disposition, which can give each part its "name." The value piece of each name/value pair is the payload of each part of the MIME message. The MIME spec gives us more options when representing the value payload -- we can choose a more efficient encoding of binary data to save bandwidth (e.g. base 64 or even raw binary).

Why not use multipart/form-data all the time? For short alphanumeric values (like most web forms), the overhead of adding all of the MIME headers is going to significantly outweigh any savings from more efficient binary encoding.

You are doing a cartesian join. This means that if you wouldn't have even have the single where clause, the number of results you get would be book_customer size times books size times book_order size times publisher size.

In order words, the result set gets blown up because you didn't add meaningful join clauses. Your correct query should look something like this:

SELECT bc.firstname, bc.lastname, b.title, TO_CHAR(bo.orderdate, 'MM/DD/YYYY') "Order Date", p.publishername
FROM book_customer bc, books b, book_order bo, publisher p
WHERE bc.book_id = b.book_id
AND bo.book_id = b.book_id
(etc.)
AND publishername = 'PRINTING IS US';

Note: usually it is adviced to not use the implicit joins like in this query, but use the INNER JOIN syntax. I am assuming however, that this syntax is used in your study material so I've left it in.

Swift 3

func getTime() -> (hour: Int, minute: Int,second: Int) {
        let hour = 1
        let minute = 20
        let second = 55
        return (hour, minute, second)
    }

To use :

let(hour, min,sec) = self.getTime()
print(hour,min,sec)

Since he was asking to do it all in the same line using split so i suggest this:

lastone = one.split("-")[(one.split("-")).length -1]  

I always avoid defining new variables as far as I can, and I find it a very good practice

Actually, the section from where you took that code offers an explanation as well:

To move n discs from peg A to peg C:

1. move n-1 discs from A to B. This leaves disc #n alone on peg A
2. move disc #n from A to C
3. move n-1 discs from B to C so they sit on disc #n

It's pretty clear that you first have to remove n - 1 discs to get access to the nth one. And that you have to move them first to another peg than where you want the full tower to appear.

The code in your post has three arguments, besides the number of discs: A source peg, a destination peg and a temporary peg on which discs can be stored in between (where every disc with size n - 1 fits).

The recursion happens actually twice, there, once before the writeln, once after. The one before the writeln will move n - 1 discs onto the temporary peg, using the destination peg as temporary storage (the arguments in the recursive call are in different order). After that, the remaining disc will be moved to the destination peg and afterwards the second recursion compeltes the moving of the entire tower, by moving the n - 1 tower from the temp peg to the destination peg, above disc n.

require 'time'
require 'date'

t = Time.now
d = DateTime.now

dd = DateTime.parse(t.to_s)
tt = Time.parse(d.to_s)

You can use this (the French locale has , for decimal separator)

NumberFormat nf = NumberFormat.getInstance(Locale.FRANCE);
nf.parse(p);

Or you can use java.text.DecimalFormat and set the appropriate symbols:

DecimalFormat df = new DecimalFormat();
DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setDecimalSeparator(',');
symbols.setGroupingSeparator(' ');
df.setDecimalFormatSymbols(symbols);
df.parse(p);

DateTime.Now.ToString("yyyyMMddHHmmss"); // case sensitive

You should use PRIMARY from key_column_usage.constraint_name = "PRIMARY"

sample query,

SELECT k.column_name as PK, concat(tbl.TABLE_SCHEMA, '.`', tbl.TABLE_NAME, '`') as TABLE_NAME
FROM information_schema.TABLES tbl
JOIN information_schema.key_column_usage k on k.table_name = tbl.table_name
WHERE k.constraint_name='PRIMARY'
  AND tbl.table_schema='MYDB'
  AND tbl.table_type="BASE TABLE";

Via the page Git Submodule Tutorial:

To remove a submodule you need to:

1. Delete the relevant section from the .gitmodules file.
2. Stage the .gitmodules changes:
   git add .gitmodules
3. Delete the relevant section from .git/config.
4. Remove the submodule files from the working tree and index:
   git rm --cached path_to_submodule (no trailing slash).
5. Remove the submodule's .git directory:
   rm -rf .git/modules/path_to_submodule
6. Commit the changes:
   git commit -m "Removed submodule <name>"
7. Delete the now untracked submodule files:
   rm -rf path_to_submodule

// if is readable / directory 
// Beware ! recursive scan eats ressources ! 
else

You can use this function to add an child to a DOM element.

function addElement(parentId, elementTag, elementId, html) 

 {


// Adds an element to the document


    var p = document.getElementById(parentId);
    var newElement = document.createElement(elementTag);
    newElement.setAttribute('id', elementId);
    newElement.innerHTML = html;
    p.appendChild(newElement);
}



function removeElement(elementId) 

{

    // Removes an element from the document
    var element = document.getElementById(elementId);
    element.parentNode.removeChild(element);
}

I think its a bug, please apply the workaround and then try again: http://support.microsoft.com/kb/281517.

Also, go into Advanced tab, and confirm if Target columns length is Varchar(max).

Try adding 2 spaces (or a backslash \) after the first line:

Look at an HTML parser such as TagSoup, HTMLCleaner or NekoHTML.

What is your output when you do java -version? This will tell you what version the running JVM is.

The Unsupported major.minor version 51.0 error could mean:

• Your server is running a lower Java version then the one used to compile your Servlet and vice versa

Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)

See: http://www.java.com/en/download/manual.jsp (7 Update 25 )

and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)

for the latest version of the JRE and JDK respectively.

EDIT:

Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.

Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

It is not that easier?

You can add the command in the /etc/rc.local script that is executed at the end of startup.

Write the command before exit 0. Anything written after exit 0 will never be executed.

The double \ should work for Windows, but you still need to take care of the folders you mention in your path. All of them (exept the filename) must exist. otherwise you will get an error.

As for "Why not use int or unsigned int?", simply because it's semantically more meaningful not to. There's the practical reason that it can be, say, typedefd as an int and then upgraded to a long later, without anyone having to change their code, of course, but more fundamentally than that a type is supposed to be meaningful. To vastly simplify, a variable of type size_t is suitable for, and used for, containing the sizes of things, just like time_t is suitable for containing time values. How these are actually implemented should quite properly be the implementation's job. Compared to just calling everything int, using meaningful typenames like this helps clarify the meaning and intent of your program, just like any rich set of types does.

If you are unable to set this up in IIS for whatever reason, I'd make an HTTP module that does the redirect for you:

using System;
using System.Web;

namespace HttpsOnly
{
    /// <summary>
    /// Redirects the Request to HTTPS if it comes in on an insecure channel.
    /// </summary>
    public class HttpsOnlyModule : IHttpModule
    {
        public void Init(HttpApplication app)
        {
            // Note we cannot trust IsSecureConnection when 
            // in a webfarm, because usually only the load balancer 
            // will come in on a secure port the request will be then 
            // internally redirected to local machine on a specified port.

            // Move this to a config file, if your behind a farm, 
            // set this to the local port used internally.
            int specialPort = 443;

            if (!app.Context.Request.IsSecureConnection 
               || app.Context.Request.Url.Port != specialPort)
            {
               app.Context.Response.Redirect("https://" 
                  + app.Context.Request.ServerVariables["HTTP_HOST"] 
                  + app.Context.Request.RawUrl);    
            }
        }

        public void Dispose()
        {
            // Needed for IHttpModule
        }
    }
}

Then just compile it to a DLL, add it as a reference to your project and place this in web.config:

 <httpModules>
      <add name="HttpsOnlyModule" type="HttpsOnly.HttpsOnlyModule, HttpsOnly" />
 </httpModules>

There is a tiny workaround script on Google Code that worked for me:

http://code.google.com/p/download-data-uri/

It adds a form with the data in it, submits it and then removes the form again. Hacky, but it did the job for me. Requires jQuery.

This thread showed up in Google before the Google Code page and I thought it might be helpful to have the link in here, too.

Interpreted language is executed at the run time according to the instructions like in shell scripting and compiled language is one which is compiled (changed into Assembly language, which CPU can understand ) and then executed like in c++.

In other words, is there a better solution than needing to specify the format?

Yes, there is now (ie in late 2016), thanks to anytime::anydate from the anytime package.

See the following for some examples from above:

R> anydate(c("01 Jan 2000", "01/01/2000", "2015/10/10"))
[1] "2000-01-01" "2000-01-01" "2015-10-10"
R> 

As you said, these are in fact unambiguous and should just work. And via anydate() they do. Without a format.

On Fedora 19, it looks like the answer is /var/log/messages. Although check /etc/rsyslog.conf if it has been changed.

You gave the answer: -2 will autosize the column to the length of the text in the column header, -1 will autosize to the longest item in the column. All according to MSDN. Note though that in the case of -1, you will need to set the column width after adding the item(s). So if you add a new item, you will also need to assign the width property of the column (or columns) that you want to autosize according to data in ListView control.

public static Bitmap RotateBitmap(Bitmap source, float angle)
{
      Matrix matrix = new Matrix();
      matrix.postRotate(angle);
      return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(), matrix, true);
}

To get Bitmap from resources:

Bitmap source = BitmapFactory.decodeResource(this.getResources(), R.drawable.your_img);

your problem is why your code doesn't work.

this your code:

Firebase ref = new Firebase(FIREBASE_URL);

  ref.addValueEventListener(new ValueEventListener() {
      @Override
      public void onDataChange(DataSnapshot snapshot) {
          Log.e("Count " ,""+snapshot.getChildrenCount());
          for (DataSnapshot postSnapshot: snapshot.getChildren()) {
            <YourClass> post = postSnapshot.getValue(<YourClass>.class);
            Log.e("Get Data", post.<YourMethod>());
          }
      }
      @Override
      public void onCancelled(FirebaseError firebaseError) {
          Log.e("The read failed: " ,firebaseError.getMessage());
      }
  })

you miss the simplest thing: getChildren()

FirebaseDatabase db = FirebaseDatabase.getInstance();
DatabaseReference reference = FirebaseAuth.getInstance().getReference("Donald Trump");

reference.addValueEventListener(new ValueEventListener() {
   @Override
   public void onDataChange(DataSnapshot dataSnapshot) {

            int count = (int) dataSnapshot.getChildrenCount(); // retrieve number of childrens under Donald Trump

            String[] hairColors = new String[count];

            index = 0;
            for (DataSnapshot datas : dataSnapshot.getChildren()){

                hairColors[index] = datas.getValue(String.class);

            }
            index ++

            for (int i = 0; i < count; i++)
            Toast(MainActivity.this, "hairColors : " + hairColors[i], toast.LENGTH_SHORT).show();

            }

    }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }

    });

Hardcoding a password in an expect script is the same as having a passwordless sudo, actually worse, since sudo at least logs its commands.

You need to write all the lines you read into the output file, even if you don't change them.

Something like:

using (var input = File.OpenText("input.txt"))
using (var output = new StreamWriter("output.txt")) {
  string line;
  while (null != (line = input.ReadLine())) {
     // optionally modify line.
     output.WriteLine(line);
  }
}

If you want to perform this operation in place then the easiest way is to use a temporary output file and at the end replace the input file with the output.

File.Delete("input.txt");
File.Move("output.txt", "input.txt");

(Trying to perform update operations in the middle of text file is rather hard to get right because always having the replacement the same length is hard given most encodings are variable width.)

EDIT: Rather than two file operations to replace the original file, better to use File.Replace("input.txt", "output.txt", null). (See MSDN.)

You have to use val() instead of value() and you have missed starting quote id=dbType" should be id="dbType"

Both answers didn't mention the awaitable Task.WhenAll:

var task1 = DoWorkAsync();
var task2 = DoMoreWorkAsync();

await Task.WhenAll(task1, task2);

The main difference between Task.WaitAll and Task.WhenAll is that the former will block (similar to using Wait on a single task) while the latter will not and can be awaited, yielding control back to the caller until all tasks finish.

More so, exception handling differs:

Task.WaitAll:

At least one of the Task instances was canceled -or- an exception was thrown during the execution of at least one of the Task instances. If a task was canceled, the AggregateException contains an OperationCanceledException in its InnerExceptions collection.

Task.WhenAll:

If any of the supplied tasks completes in a faulted state, the returned task will also complete in a Faulted state, where its exceptions will contain the aggregation of the set of unwrapped exceptions from each of the supplied tasks.

If none of the supplied tasks faulted but at least one of them was canceled, the returned task will end in the Canceled state.

If none of the tasks faulted and none of the tasks were canceled, the resulting task will end in the RanToCompletion state. If the supplied array/enumerable contains no tasks, the returned task will immediately transition to a RanToCompletion state before it's returned to the caller.

I use

button {text-indent:-9999px;}
* html button{font-size:0;display:block;line-height:0}  /* ie6 */
*+html button{font-size:0;display:block;line-height:0}  /* ie7 */

Keep track of your index: That's how it is done in Java:

 int index = 0;
    for (Element song: question){
        // Do whatever
         index++;
    }

If you are referring to com.example.app, no I understand you can't it would be considered a new app

solve this problem successfully

I my case, I tried all the suggestions above. But, at some point I realized that the problem persists even if Resharper is suspended. So, I looked for similar problem in VS itself and found the solution in the comments for the accepted answer in this SO post.

I'm listing my steps for brevity.

1. VS -> Tools -> Options -> ReSharper Suspend button
2. Build solution. Notice all references still unresolved
3. Clean the solution
4. Restart VS
5. Build the solution without Resharper. Notice all references resolved
6. VS -> Tools -> Options -> ReSharper Resume button

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

Controller:

[HttpPost]
public ActionResult Create(FormCollection collection)
{
    try
    {
        CommonServiceReference.tbl_user user = new CommonServiceReference.tbl_user();
        user.user_gender = collection["rdbtnGender"];
        return RedirectToAction("Index");
    }
    catch(Exception e)
    {
        throw e;
    }
}

public ActionResult Edit(int id)
{
    CommonServiceReference.ViewUserGroup user = clientObj.getUserById(id);
    ViewBag.UserObj = user;
    return View();
}

VIEW:

Create:

<input type="radio" id="rdbtnGender1" name="rdbtnGender" value="Male" required>
<label for="rdbtnGender1">MALE</label>
<input type="radio" id="rdbtnGender2" name="rdbtnGender" value="Female" required>
<label  for="rdbtnGender2">FEMALE</label>

Edit:

<input type="radio" id="rdbtnGender1" name="rdbtnGender" value="Male" @(ViewBag.UserObj.user_gender == "Male" ? "checked='true'" : "") required>
<label for="rdbtnGender1">MALE</label>

<input type="radio" id="rdbtnGender2" name="rdbtnGender" value="Female" @(ViewBag.UserObj.user_gender == "Female" ? "checked='true'" : "") required>
<label for="rdbtnGender2">FEMALE</label>

Unfortunately, there is no perfect IDE for Android. Eclipse has more features as it is the only IDE google developed plugin for. However, if you are just like me, tired of crashes and weired debug/develop mode swithes, Use Netbeans plugin from http://nbandroid.kenai.com.

If you have a well-formed JSON string, you should be able to do

var as = JSON.parse(jstring);

I do this all the time when transfering arrays through AJAX.

Another way to accomplish this is with the jq "--arg" flag. Using the original example:

#!/bin/sh

#this works ***
projectID=$(cat file.json | jq -r '.resource[] | 
select(.username=="[email protected]") | .id')
echo "$projectID"

[email protected]

# Use --arg to pass the variable to jq. This should work:
projectID=$(cat file.json | jq --arg EMAILID $EMAILID -r '.resource[] 
| select(.username=="$EMAILID") | .id')
echo "$projectID"

See here, which is where I found this solution: https://github.com/stedolan/jq/issues/626

sudo lsof -i:8080

By running the above command you can see what are all the jobs running.

kill -9 <PID Number>

Enter the PID (process identification number), so this will terminate/kill the instance.

Execute the following procedure for example as user system.

Set p_owner to the schema owner and p_readonly to the name of the readonly user.

create or replace
procedure createReadOnlyUser(p_owner in varchar2, p_readonly in varchar2) 
AUTHID CURRENT_USER is
BEGIN
    execute immediate 'create user '||p_readonly||' identified by '||p_readonly;
    execute immediate 'grant create session to '||p_readonly;
    execute immediate 'grant select any dictionary to '||p_readonly;
    execute immediate 'grant create synonym to '||p_readonly;

   FOR R IN (SELECT owner, object_name from all_objects where object_type in('TABLE', 'VIEW') and owner=p_owner) LOOP
      execute immediate 'grant select on '||p_owner||'.'||R.object_name||' to '||p_readonly;
   END LOOP;
   FOR R IN (SELECT owner, object_name from all_objects where object_type in('FUNCTION', 'PROCEDURE') and owner=p_owner) LOOP
      execute immediate 'grant execute on '||p_owner||'.'||R.object_name||' to '||p_readonly;
   END LOOP;
   FOR R IN (SELECT owner, object_name FROM all_objects WHERE object_type in('TABLE', 'VIEW') and owner=p_owner) LOOP
      EXECUTE IMMEDIATE 'create synonym '||p_readonly||'.'||R.object_name||' for '||R.owner||'."'||R.object_name||'"';
   END LOOP;
   FOR R IN (SELECT owner, object_name from all_objects where object_type in('FUNCTION', 'PROCEDURE') and owner=p_owner) LOOP
      execute immediate 'create synonym '||p_readonly||'.'||R.object_name||' for '||R.owner||'."'||R.object_name||'"';
   END LOOP;
END;

These do the same thing:

window.location.assign(url);
window.location = url;
window.location.href = url;

They simply navigate to the new URL. The replace method on the other hand navigates to the URL without adding a new record to the history.

So, what you have read in those many forums is not correct. The assign method does add a new record to the history.

I had this exact issue when developing a Spring Boot application in STS, but ultimately deploying the packaged war to WebSphere(v.9). Based on previous answers my situation was unique. ojdbc8.jar was in my WEB-INF/lib folder with Parent Last class loading set, but always it says it failed to find the suitable driver.

My ultimate issue was that I was using the incorrect DataSource class because I was just following along with online tutorials/examples. Found the hint thanks to David Dai comment on his own question here: Spring JDBC Could not load JDBC driver class [oracle.jdbc.driver.OracleDriver]

Also later found spring guru example with Oracle specific driver: https://springframework.guru/configuring-spring-boot-for-oracle/

Example that throws error using org.springframework.jdbc.datasource.DriverManagerDataSource based on generic examples.

@Config
@EnableTransactionManagement
public class appDataConfig {
 \* Other Bean Defs *\
    @Bean
    public DataSource dataSource() {
        // configure and return the necessary JDBC DataSource
        DriverManagerDataSource dataSource = new DriverManagerDataSource("jdbc:oracle:thin:@//HOST:PORT/SID", "user", "password");
        dataSource.setSchema("MY_SCHEMA");
        return dataSource;
    }
}

And the corrected exapmle using a oracle.jdbc.pool.OracleDataSource:

@Config
@EnableTransactionManagement
public class appDataConfig {
/* Other Bean Defs */
@Bean
    public DataSource dataSource() {
        // configure and return the necessary JDBC DataSource
        OracleDataSource datasource = null;
        try {
            datasource = new OracleDataSource();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        datasource.setURL("jdbc:oracle:thin:@//HOST:PORT/SID");
        datasource.setUser("user");
        datasource.setPassword("password");

        return datasource;
    }
}

Edit

A better way to do this is:

1. Create your own less file as a main less file ( like bootstrap.less ).

2. Import all bootstrap less files you need. (in this case, you just need to Import all responsive less files but responsive-1200px-min.less)

3. If you need to modify anything in original bootstrap less file, you just need to write your own less to overwrite bootstrap's less code. (Just remember to put your less code/file after @import { /* bootstrap's less file */ };).

Original

I have the same problem. This is how I fixed it.

Find the media query:

@media (max-width:1200px) ...

Remove it. (I mean the whole thing , not just @media (max-width:1200px))

Since the default width of Bootstrap is 940px, you don't need to do anything.

If you want to have your own max-width, just modify the css rule in the media query that matches your desired width.

You could use this query to display Foreign key constaraints:

SELECT
K_Table = FK.TABLE_NAME,
FK_Column = CU.COLUMN_NAME,
PK_Table = PK.TABLE_NAME,
PK_Column = PT.COLUMN_NAME,
Constraint_Name = C.CONSTRAINT_NAME
FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS C
INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS FK ON C.CONSTRAINT_NAME = FK.CONSTRAINT_NAME
INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS PK ON C.UNIQUE_CONSTRAINT_NAME = PK.CONSTRAINT_NAME
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE CU ON C.CONSTRAINT_NAME = CU.CONSTRAINT_NAME
INNER JOIN (
SELECT i1.TABLE_NAME, i2.COLUMN_NAME
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS i1
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE i2 ON i1.CONSTRAINT_NAME = i2.CONSTRAINT_NAME
WHERE i1.CONSTRAINT_TYPE = 'PRIMARY KEY'
) PT ON PT.TABLE_NAME = PK.TABLE_NAME
---- optional:
ORDER BY
1,2,3,4
WHERE PK.TABLE_NAME='YourTable'

Taken from http://blog.sqlauthority.com/2006/11/01/sql-server-query-to-display-foreign-key-relationships-and-name-of-the-constraint-for-each-table-in-database/

You need:

#include <string.h> /* memset */
#include <unistd.h> /* close */

in your code.

References: POSIX for close, the C standard for memset.

<li>s don't have a value - only form inputs do. In fact, you're not supposed to even include the value attribute in the HTML for <li>s.

You can rely on .innerHTML instead:

getPaging(this.innerHTML)

Or maybe the id:

getPaging(this.id);

However, it's easier (and better practice) to add the click handlers from JavaScript code, and not include them in the HTML. Seeing as you're already using jQuery, this can easily be done by changing your HTML to:

<li class="clickMe">1</li>
<li class="clickMe">2</li>

And use the following JavaScript:

$(function () {
    $('.clickMe').click(function () {
        var str = $(this).text();
        $('#loading-content').load('dataSearch.php?' + str, hideLoader);
    });
});

This will add the same click handler to all your <li class="clickMe">s, without requiring you to duplicate your onclick="getPaging(this.value)" code for each of them.

Late as usual. If anyone is still interested in this there are a number of related SO questions and answers. My version of recursive extension method for resolving this:

public static IEnumerable<T> FindControlsOfType<T>(this Control parent)
                                                        where T : Control
{
    foreach (Control child in parent.Controls)
    {
        if (child is T)
        {
            yield return (T)child;
        }
        else if (child.Controls.Count > 0)
        {
            foreach (T grandChild in child.FindControlsOfType<T>())
            {
                yield return grandChild;
            }
        }
    }
}

SWIFT 2.x

let extendedURLString = urlString.stringByAppendingString("&requireslogin=true")

SWIFT 3.0

From Documentation: "You can append a Character value to a String variable with the String type’s append() method:" so we cannot use append for Strings.

urlString += "&requireslogin=true"

"+" Operator works in both versions

let extendedURLString = urlString+"&requireslogin=true"

Generics can't use primitive types in the form of keywords.

Use

public HashMap<Character, Integer> buildMap(String letters)
{
    HashMap<Character, Integer> checkSum = new HashMap<Character, Integer>();

    for ( int i = 0; i < letters.length(); ++i )
    {
        checkSum.put(letters.charAt(i), primes[i]);
    }

    return checkSum;
}

Updated: With Java 7 and later, you can use the diamond operator.

HashMap<Character, Integer> checkSum = new HashMap<>();

Here's what reliably works for me on macOS. Make sure to replace example.com and 443 with the actual hostname and port you're trying to connect to, and give a custom alias. The first command downloads the provided certificate from the remote server and saves it locally in x509 format. The second command loads the saved certificate into Java's SSL trust store.

openssl x509 -in <(openssl s_client -connect example.com:443 -prexit 2>/dev/null) -out ~/example.crt
sudo keytool -importcert -file ~/example.crt -alias example -keystore $(/usr/libexec/java_home)/jre/lib/security/cacerts -storepass changeit

To remove all files from a directory, first you need to list all files in the directory using fs.readdir, then you can use fs.unlink to remove each file. Also fs.readdir will give just the file names, you need to concat with the directory name to get the full path.

Here is an example

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

const directory = 'test';

fs.readdir(directory, (err, files) => {
  if (err) throw err;

  for (const file of files) {
    fs.unlink(path.join(directory, file), err => {
      if (err) throw err;
    });
  }
});

Update node version 14

There is a recursive flag that you can use in rmdir to remove all the files recursively. See nodejs docs for more information.

const fs = require('fs').promises;

const directory = 'test';

fs.rmdir(directory, { recursive: true })
  .then(() => console.log('directory removed!'));

You can use the runners token for CI/CD Pipelines of your GitLab repo.

git clone https://gitlab-ci-token:<runners token>@git.example.com/myuser/myrepo.git

Where <runners token> can be obtained from:

git.example.com/myuser/myrepo/pipelines/settings

or by clicking on the Settings icon -> CI/CD Pipeline and look for Runners Token on the page

Screenshot of the runners token location:

If the element is currently not visible on the page, you can use the native scrollIntoView() method.

$('#div_' + element_id)[0].scrollIntoView( true );

Where true means align to the top of the page, and false is align to bottom.

Otherwise, there's a scrollTo() plugin for jQuery you can use.

Or maybe just get the top position()^(docs) of the element, and set the scrollTop()^(docs) to that position:

var top = $('#div_' + element_id).position().top;
$(window).scrollTop( top );

You can also use chr(176) to print the degree sign. Here is an example using python 3.6.5 interactive shell:

You can use papaparse.js like the example below:

<!DOCTYPE html>
<html lang="en">

    <head>
        <title>CSV</title>
    </head>

    <body>
        <input type="file" id="files" multiple="">
        <button onclick="csvGetter()">CSV Getter</button>
        <h3>The Result will be in the Console.</h3>

        <script src="papaparse.min.js"></script>

        <script>
            function csvGetter() {

                var file = document.getElementById('files').files[0];
                Papa.parse(file, {
                    complete: function(results) {
                        console.log(results.data);
                    }
                });
            }
          </script>
    </body>

</html>

Don't forget to include papaparse.js in the same folder.

SetRetainInstance(true) allows the fragment sort of survive. Its members will be retained during configuration change like rotation. But it still may be killed when the activity is killed in the background. If the containing activity in the background is killed by the system, it's instanceState should be saved by the system you handled onSaveInstanceState properly. In another word the onSaveInstanceState will always be called. Though onCreateView won't be called if SetRetainInstance is true and fragment/activity is not killed yet, it still will be called if it's killed and being tried to be brought back.

Here are some analysis of the android activity/fragment hope it helps. http://ideaventure.blogspot.com.au/2014/01/android-activityfragment-life-cycle.html

It means there's no default document in that directory (index.html, index.php, etc...). On most webservers, that would mean it would show a listing of the directory's contents. But showing that directory is forbidden by server configuration (Options -Indexes)

You need to do this to display image

$sqlimage  = "SELECT image FROM userdetail where `id` = $id1";
$imageresult1 = mysql_query($sqlimage);

while($rows=mysql_fetch_assoc($imageresult1))
{
    $image = $rows['image'];
    echo "<img src='$image' >";
    echo "<br>";
} 

You need to use html img tag.

Adding more to Jason's more generalized way of retrieving the POST data or GET data

from flask_restful import reqparse

def parse_arg_from_requests(arg, **kwargs):
    parse = reqparse.RequestParser()
    parse.add_argument(arg, **kwargs)
    args = parse.parse_args()
    return args[arg]

form_field_value = parse_arg_from_requests('FormFieldValue')

I have not found a satisfying answer for this question, i.e how to load edit, run and save. Overwriting either using %%writefile or %save -f doesn't work well if you want to show incremental changes in git. It would look like you delete all the lines in filename.py and add all new lines, even though you just edit 1 line.

If the selector is contained within a variable, the code below may be helpful:

selector_name = $this.attr('name');
//selector_name = users[0][first:name]

escaped_selector_name = selector_name.replace(/(:|\.|\[|\])/g,'\\$1');
//escaped_selector_name = users\\[0\\]\\[first\\:name\\]

In this case we prefix all special characters with double backslash.
