Here is my solution:

import (
    "bytes"
    "encoding/json"
)

const (
    empty = ""
    tab   = "\t"
)

func PrettyJson(data interface{}) (string, error) {
    buffer := new(bytes.Buffer)
    encoder := json.NewEncoder(buffer)
    encoder.SetIndent(empty, tab)

    err := encoder.Encode(data)
    if err != nil {
       return empty, err
    }
    return buffer.String(), nil
}

Here are a few thoughts: Firstly, if you're genuinely concerned about the runtime of your code, be sure to know what happens when you call the built-in functions! I don't know up from down in javascript, but a quick google of the splice function returned this, which seems to indicate that you're creating a whole new array each call! I don't know if it actually matters, but it is certainly related to efficiency. I see that Breton, in the comments, has already pointed this out, but it certainly holds for whatever array-manipulating function you choose.

Anyways, onto actually solving the problem.

When I read that you wanted to sort, my first thought is to use insertion sort!. It is handy because it runs in linear time on sorted, or nearly-sorted lists. As your arrays will have only 1 element out of order, that counts as nearly-sorted (except for, well, arrays of size 2 or 3 or whatever, but at that point, c'mon). Now, implementing the sort isn't too too bad, but it is a hassle you may not want to deal with, and again, I don't know a thing about javascript and if it will be easy or hard or whatnot. This removes the need for your lookup function, and you just push (as Breton suggested).

Secondly, your "quicksort-esque" lookup function seems to be a binary search algorithm! It is a very nice algorithm, intuitive and fast, but with one catch: it is notoriously difficult to implement correctly. I won't dare say if yours is correct or not (I hope it is, of course! :)), but be wary if you want to use it.

Anyways, summary: using "push" with insertion sort will work in linear time (assuming the rest of the array is sorted), and avoid any messy binary search algorithm requirements. I don't know if this is the best way (underlying implementation of arrays, maybe a crazy built-in function does it better, who knows), but it seems reasonable to me. :) - Agor.

As your methods an int datatype, you should use "==" instead of equals()

try replacing this if (id.equals(list[pos].getItemNumber()))

with

if (id.equals==list[pos].getItemNumber())

it will fix the error .

On rails 4.2, to remove all data but preserve the database

$ bin/rake db:purge && bin/rake db:schema:load

https://github.com/rails/rails/blob/4-2-stable/activerecord/CHANGELOG.md

Try below code:

String empty = "-";
if (row.getCell(3) == null || row.getCell(3).getCellType() == Cell.CELL_TYPE_BLANK) {
    upld.setValue(empty);
} else {
    upld.setValue(row.getCell(3).getStringCellValue());
}

The simplest way to insert a new line between echo statements is to insert an echo without arguments, for example:

echo Create the snapshots
echo
echo Snapshot created

That is, echo without any arguments will print a blank line.

Another alternative to use a single echo statement with the -e flag and embedded newline characters \n:

echo -e "Create the snapshots\n\nSnapshot created"

However, this is not portable, as the -e flag doesn't work consistently in all systems. A better way if you really want to do this is using printf:

printf "Create the snapshots\n\nSnapshot created\n"

This works more reliably in many systems, though it's not POSIX compliant. Notice that you must manually add a \n at the end, as printf doesn't append a newline automatically as echo does.

From within less (in Linux):

 g and the line number to go forward

 G and the line number to go backwards

Used alone, g and G will take you to the first and last line in a file respectively; used with a number they are both equivalent.

An example; you want to go to line 320123 of a file,

press 'g' and after the colon type in the number 320123

Additionally you can type '-N' inside less to activate / deactivate the line numbers. You can as a matter of fact pass any command line switches from inside the program, such as -j or -N.

NOTE: You can provide the line number in the command line to start less (less +number -N) which will be much faster than doing it from inside the program:

less +12345 -N /var/log/hugelogfile

This will open a file displaying the line numbers and starting at line 12345

$('element[id$=txtTitle]')

It's not strictly necessary to quote the text fragment you are matching against

As an even easier solution, you could just use:

$results = $objects.Name

Which should fill $results with an array of all the 'Name' property values of the elements in $objects.

$("button").click(function() {
    alert(this.id); // or alert($(this).attr('id'));
});

As long as you don't want any special formatting: yes.

foreach ($_POST as $key => $value) 
    $body .= $key . ' -> ' . $value . '<br>';

Obviously, more formatting would be necessary, however that's the "easy" way. Unless I misunderstood the question.

You could also do something like this (and if you like the format, it's certainly easier):

$body = print_r($_POST, true);

It's not what the question asks but I used @Rich Drummond 's answer for a char array read in from stdin which is null terminated.

char *buff;
size_t buff_size = 100;
int choice;
do{
    buff = (char *)malloc(buff_size *sizeof(char));
    getline(&buff, &buff_size, stdin);
    choice = atoi(buff);
    free(buff);
                    
}while((choice<1)&&(choice>9));

>>> a = np.random.randint(0, 5, size=(5, 4))
>>> a
array([[0, 3, 3, 2],
       [4, 1, 1, 2],
       [3, 4, 2, 4],
       [2, 4, 3, 0],
       [1, 2, 3, 4]])
>>> 
>>> a[a > 3] = -101
>>> a
array([[   0,    3,    3,    2],
       [-101,    1,    1,    2],
       [   3, -101,    2, -101],
       [   2, -101,    3,    0],
       [   1,    2,    3, -101]])

See, eg, Indexing with boolean arrays.

x is Unsigned hexadecimal integer ( 32 Bit )

p is Pointer address

See printf on the C++ Reference. Even if both of them would write the same, I would use %p to print a pointer.

I used the display:inline-block property: the solution consist in use a wrapper with fixed width. Inside, the ul block with the inline-block for display. Using this, the ul just take the width for the real content! and finally margin: 0 auto, to center this inline-block =)

/*ul wrapper*/
.gallery_wrapper{
        width:          958px;
        margin:         0 auto;
  }
/*ul list*/
ul.gallery_carrousel{
        display:        inline-block;
        margin:         0 auto;
}
.contenido_secundario li{
        float:          left;
}

CMP subtracts the operands and sets the flags. Namely, it sets the zero flag if the difference is zero (operands are equal).

TEST sets the zero flag, ZF, when the result of the AND operation is zero. If two operands are equal, their bitwise AND is zero when both are zero. TEST also sets the sign flag, SF, when the most significant bit is set in the result, and the parity flag, PF, when the number of set bits is even.

JE [Jump if Equals] tests the zero flag and jumps if the flag is set. JE is an alias of JZ [Jump if Zero] so the disassembler cannot select one based on the opcode. JE is named such because the zero flag is set if the arguments to CMP are equal.

So,

TEST %eax, %eax
JE   400e77 <phase_1+0x23>

jumps if the %eax is zero.

If you want to ensure they all get called, use super at all levels.

Shorter than the accepted answer, doing the same, but keeping it simple:

window.location.search += '&param=42';

We don't have to alter the entire url, just the query string, known as the search attribute of location.

When you are assigning a value to the search attribute, the question mark is automatically inserted by the browser and the page is reloaded.

s = s.length() > 10 ? s.substring(0, 9) : s;

This is very useful to avoid errors when accessing properties of null or undefined objects.

null to undefined object

const obj = null;
const newObj = obj || undefined;
// newObj = undefined

undefined to empty object

const obj; 
const newObj = obj || {};
// newObj = {}     
// newObj.prop = undefined, but no error here

null to empty object

const obj = null;
const newObj = obj || {};
// newObj = {}  
// newObj.prop = undefined, but no error here

The solution I came up with was as follows:

1. Create the SQL query in your favorite query dev tool
2. In Crystal Reports, within the main report, create parameter to pass to the subreport
3. Create sub report, using the 'Add Command' option in the 'Data' portion of the 'Report Creation Wizard' and the SQL query from #1.

4. Once the subreport is added to the main report, right click on the subreport, choose 'Change Subreport Links...', select the link field, and uncheck 'Select data in subreport based on field:'

   NOTE: You may have to initially add the parameter with the 'Select data in subreport based on field:' checked, then go back to 'Change Subreport Links ' and uncheck it after the subreport has been created.

5. In the subreport, click the 'Report' menu, 'Select Expert', use the 'Formula Editor', set the SQL column from #1 either equal to or like the parameter(s) selected in #4.

                   (Subreport SQL Column)  (Parameter from Main Report)
           Example:  {Command.Project} like {?Pm-?Proj_Name}
   

(Tested for pandas 1.0.5)
Based on @athlonshi answer (it had ValueError: could not convert string to float: 'big', on C column), full working example without warning:

import pandas as pd
from sklearn.preprocessing import MinMaxScaler
scale = preprocessing.MinMaxScaler()

df = pd.DataFrame({
           'A':[14.00,90.20,90.95,96.27,91.21],
           'B':[103.02,107.26,110.35,114.23,114.68], 
           'C':['big','small','big','small','small']
         })
print(df)
df[["A","B"]] = pd.DataFrame(scale.fit_transform(df[["A","B"]].values), columns=["A","B"], index=df.index)
print(df)

       A       B      C
0  14.00  103.02    big
1  90.20  107.26  small
2  90.95  110.35    big
3  96.27  114.23  small
4  91.21  114.68  small
          A         B      C
0  0.000000  0.000000    big
1  0.926219  0.363636  small
2  0.935335  0.628645    big
3  1.000000  0.961407  small
4  0.938495  1.000000  small

Angular JS does this way.

msie = parseInt((/msie (\d+)/.exec(navigator.userAgent.toLowerCase()) || [])[1]);
if (isNaN(msie)) {
  msie = parseInt((/trident\/.*; rv:(\d+)/.exec(navigator.userAgent.toLowerCase()) || [])[1]);
}

msie will be positive number if its IE and NaN for other browser like chrome,firefox.

why ?

As of Internet Explorer 11, the user-agent string has changed significantly.

refer this :

msdn #1 msdn #2

HTML frames, but it is not an ideal solution. You would essentially be accessing 3 separate HTML pages at once.

Your other option is to use AJAX I think.

The solution of Jamie Flournoy works great. Here is a bit enhanced version to keep the .htaccess :

# Ignore everything in this directory
*
# Except this file
!.gitignore
!.htaccess

With this solution you are able to commit a empty folder, for example /log, /tmp or /cache and the folder will stay empty.

Based on what I read from different sources:

An await expression does not block the thread on which it is executing. Instead, it causes the compiler to sign up the rest of the async method as a continuation on the awaited task. Control then returns to the caller of the async method. When the task completes, it invokes its continuation, and execution of the async method resumes where it left off.

To wait for a single task to complete, you can call its Task.Wait method. A call to the Wait method blocks the calling thread until the single class instance has completed execution. The parameterless Wait() method is used to wait unconditionally until a task completes. The task simulates work by calling the Thread.Sleep method to sleep for two seconds.

This article is also a good read.

link_to "+ Service", controller_action_path(:account_id => acct.id)

If it is still not working check the path:

$ rake routes

I have tried both the options suggested by Michael Munsey and works for me.

I wanted to provide another option to view the filtered tables. Mouse Right Click your table trees node and Select "Apply Filter" and check "Include Synonyms" check box and click Okay. That's it, you should be able to view the tables right there. It works for me.

Courtesy: http://www.thatjeffsmith.com/archive/2013/03/why-cant-i-see-my-tables-in-oracle-sql-developer/

That's the way I'd prefer to see if I was maintaining your code. If you manage to find a faster solution, it's going to be very esoteric, and you should really bury it inside of a method that describes what it does.

(does it still work without the ToArray)?

Using this,

        String s = "03/24/2013 21:54";
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy HH:mm");
        try
        {
            Date date = simpleDateFormat.parse(s);

            System.out.println("date : "+simpleDateFormat.format(date));
        }
        catch (ParseException ex)
        {
            System.out.println("Exception "+ex);
        }

You can simply do this

$data += array($category => $question);

If your're running on php 5.4+

$data += [$category => $question];

To avoid problems with layout_* params not being properly used, you need to make sure that when you inflate your custom layout that you specify a correct ViewGroup as a parent.

Many examples pass null here, but instead you can pass the existing Toast ViewGroup as your parent.

val toast = Toast.makeText(this, "", Toast.LENGTH_LONG)
val layout = LayoutInflater.from(this).inflate(R.layout.view_custom_toast, toast.view.parent as? ViewGroup?)
toast.view = layout
toast.show()

Here we replace the existing Toast view with our custom view. Once you have a reference to your layout "layout" you can then update any images/text views that it may contain.

This solution also prevents any "View not attached to window manager" crashes from using null as a parent.

Also, avoid using ConstraintLayout as your custom layout root, this seems to not work when used inside a Toast.

I would use something along these lines...

 netstat -rn | grep "default" | awk '{print $2}'

I think you do need to cast it, but it shouldn't be too bad:

Foo<Bar> mockFoo = (Foo<Bar>) mock(Foo.class);
when(mockFoo.getValue()).thenReturn(new Bar());

use a trigges it will work:-

->CREATE TRIGGER trigger_name BEFORE INSERT ON table_name

FOR EACH ROW SET NEW.column_name3 = NEW.column_name1 + NEW.column_name2;

this will only work only when you will insert a row in table not when you will be updating your table for such a pupose create another trigger of different name and use UPDATE on the place of INSERT in the above syntax

.myDiv {
    background-color: red;
    width: 100%;
    min-height: 100vh;
    max-height: 100%;
    position: absolute;
    top: 0;
    left: 0;
    margin: 0 auto;
}

Basically, we're fixing the div's position regardless of it's parent, and then position it using margin: 0 auto; and settings its position at the top left corner.

In a similar situation like this where I had to write Test Case which is dependent on Environment Variable, I tried following:

1. I went for System Rules as suggested by Stefan Birkner. Its use was simple. But sooner than later, I found the behavior erratic. In one run, it works, in the very next run it fails. I investigated and found that System Rules work well with JUnit 4 or higher version. But in my cases, I was using some Jars which were dependent on JUnit 3. So I skipped System Rules. More on it you can find here @Rule annotation doesn't work while using TestSuite in JUnit.
2. Next I tried to create Environment Variable through Process Builder class provided by Java. Here through Java Code we can create an environment variable, but you need to know the process or program name which I did not. Also it creates environment variable for child process, not for the main process.

I wasted a day using the above two approaches, but of no avail. Then Maven came to my rescue. We can set Environment Variables or System Properties through Maven POM file which I think best way to do Unit Testing for Maven based project. Below is the entry I made in POM file.

    <build>
      <plugins>
       <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
          <systemPropertyVariables>
              <PropertyName1>PropertyValue1</PropertyName1>                                                          
              <PropertyName2>PropertyValue2</PropertyName2>
          </systemPropertyVariables>
          <environmentVariables>
            <EnvironmentVariable1>EnvironmentVariableValue1</EnvironmentVariable1>
            <EnvironmentVariable2>EnvironmentVariableValue2</EnvironmentVariable2>
          </environmentVariables>
        </configuration>
      </plugin>
    </plugins>
  </build>

After this change, I ran Test Cases again and suddenly all worked as expected. For reader's information, I explored this approach in Maven 3.x, so I have no idea on Maven 2.x.

It may be useful for someone, so I'll post it here. I was missing this dependency on my pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>

            <artifactId>spring-boot-starter-tomcat</artifactId>

    </exclusions>
</dependency>

so weird but this worked for me.

You've just published that private key, so now the whole world knows what it is. Hopefully that was just for testing.

EDIT: Others have noted that the openssl text header of the published key, -----BEGIN RSA PRIVATE KEY-----, indicates that it is PKCS#1. However, the actual Base64 contents of the key in question is PKCS#8. Evidently the OP copy and pasted the header and trailer of a PKCS#1 key onto the PKCS#8 key for some unknown reason. The sample code I've provided below works with PKCS#8 private keys.

Here is some code that will create the private key from that data. You'll have to replace the Base64 decoding with your IBM Base64 decoder.

public class RSAToy {

    private static final String BEGIN_RSA_PRIVATE_KEY = "-----BEGIN RSA PRIVATE KEY-----\n"
            + "MIIEuwIBADAN ...skipped the rest\n"
         // + ...   
         // + ... skipped the rest
         // + ...   
            + "-----END RSA PRIVATE KEY-----";

    public static void main(String[] args) throws Exception {

        // Remove the first and last lines

        String privKeyPEM = BEGIN_RSA_PRIVATE_KEY.replace("-----BEGIN RSA PRIVATE KEY-----\n", "");
        privKeyPEM = privKeyPEM.replace("-----END RSA PRIVATE KEY-----", "");
        System.out.println(privKeyPEM);

        // Base64 decode the data

        byte [] encoded = Base64.decode(privKeyPEM);

        // PKCS8 decode the encoded RSA private key

        PKCS8EncodedKeySpec keySpec = new PKCS8EncodedKeySpec(encoded);
        KeyFactory kf = KeyFactory.getInstance("RSA");
        PrivateKey privKey = kf.generatePrivate(keySpec);

        // Display the results

        System.out.println(privKey);
    }
}

You can use the start command to do much the same thing as ShellExecute. For example

 start "" http://www.stackoverflow.com

This will launch whatever browser is the default browser, so won't necessarily launch Internet Explorer.

Just open your repository file and add this new function, then call it inside your controller:

 public function distinctCategories(){
        return $this->createQueryBuilder('cc')
        ->where('cc.contenttype = :type')
        ->setParameter('type', 'blogarticle')
        ->groupBy('cc.blogarticle')
        ->getQuery()
        ->getResult()
        ;
    }

Then within your controller:

public function index(YourRepository $repo)
{
    $distinctCategories = $repo->distinctCategories();


    return $this->render('your_twig_file.html.twig', [
        'distinctCategories' => $distinctCategories
    ]);
}

Good luck!

Once I needed to resize photos from camera for developing:

• Original filesize: 2800 kB
• Resolution: 3264x2448

Command:

mogrify -quality "97%" -resize 2048x2048 -filter Lanczos -interlace Plane -gaussian-blur 0.05 

• Result filesize 753 kB
• Resolution 2048x2048

and I can't see any changes in full screen with my 1920x1080 resolution monitor. 2048 resolution is the best for developing 10 cm photos at maximum quality of 360 dpi. I don't want to strip it.

edit: I noticed that I even get much better results without blurring. Without blurring filesize is 50% of original, but quality is better (when zooming).

@($output).Count does not always produce correct results. I used the ($output | Measure).Count method.

I found this with VMware Get-VmQuestion cmdlet:

$output = Get-VmQuestion -VM vm1
@($output).Count

The answer it gave is one, whereas

$output

produced no output (the correct answer was 0 as produced with the Measure method).

This only seemed to be the case with 0 and 1. Anything above 1 was correct with limited testing.

If you've just got the iterator then that's what you'll have to do - it doesn't know how many items it's got left to iterate over, so you can't query it for that result. There are utility methods that will seem to do this efficiently (such as Iterators.size() in Guava), but underneath they're just consuming the iterator and counting as they go, the same as in your example.

However, many iterators come from collections, which you can often query for their size. And if it's a user made class you're getting the iterator for, you could look to provide a size() method on that class.

In short, in the situation where you only have the iterator then there's no better way, but much more often than not you have access to the underlying collection or object from which you may be able to get the size directly.

The environment variable to set is MAVEN_OPTS, for example MAVEN_OPTS=-Xmx1024m. The maxmem configuration in the pom only applies when you set the compiler plugin to fork javac into a new JVM. Otherwise the plugin runs inside the same VM as Maven and thus within the memory passed on the command line via the MAVEN_OPTS.

To set MAVEN_OPTS under Windows 7:

1. Right click on My Computer and select Properties (keyboard shortcut press Windows + Pause/Break)
2. Click the Advanced System Settings link located in the left navigation of System Properties to display the Advanced System Properties
3. Go to the Advanced tab and click the Environment Variables button located at the bottom of the Advanced System Properties configuration window
4. Create a New user variable, set the Variable name to MAVEN_OPTS and set the Variable value to -Xmx1024m (or more)

Open a new command window and run mvn.

You could try this.

In windows go to Administrative Tools->Services And see scroll down to where it says Oracle[instanceNameHere] and see if the listener and the service itself are running. You might have to start it. You can also set it to start automatically when you right-click on it and go to properties.

There is no difference. Both will work in the same way.

CSS background properties are used to define the background effects of an element.

CSS properties used for background effects:

• background-color
• background-image
• background-repeat
• background-attachment
• background-position

Background property includes all of this properties and you can just write them in one line.

From the documentation:

If the pattern does not contain a slash /, git treats it as a shell glob pattern and checks for a match against the pathname relative to the location of the .gitignore file (relative to the toplevel of the work tree if not from a .gitignore file).

A leading slash matches the beginning of the pathname. For example, "/*.c" matches "cat-file.c" but not "mozilla-sha1/sha1.c".

So you should add the following line to your root .gitignore:

/config.php

Here are a couple of ways to do that:

• The JavaScript Source: Navigation: Full Screen Window
• Javascript to open a full screen window

I'd suggest, provide a popup asking the user if s/he wants to go full screen and then call this javascript accordingly.

The "Accepted" Answer is Incorrect and Incomplete

The only answers that are accurate are the @jive-dadson and @EddingtonsMonkey answers, and in support @nils-pipenbrinck. The other answers (including the accepted) are linking to or citing sources that are either wrong, irrelevant, obsolete, or broken.

Briefly:

• sRGB must be LINEARIZED before applying the coefficients.
• Luminance (L or Y) is linear as is light.
• Perceived lightness (L*) is nonlinear as is human perception.
• HSV and HSL are not even remotely accurate in terms of perception.
• The IEC standard for sRGB specifies a threshold of 0.04045 it is NOT 0.03928 (that was from an obsolete early draft).
• The be useful (i.e. relative to perception), Euclidian distances require a perceptually uniform Cartesian vector space such as CIELAB. sRGB is not one.

What follows is a correct and complete answer:

Because this thread appears highly in search engines, I am adding this answer to clarify the various misconceptions on the subject.

Luminance is a linear measure of light, spectrally weighted for normal vision but not adjusted for the non-linear perception of lightness. It can be a relative measure, Y as in CIEXYZ, or as L, an absolute measure in cd/m² (not to be confused with L*).

Perceived lightness is used by some vision models such as CIELAB, here L* (Lstar) is a value of perceptual lightness, and is non-linear to approximate the human vision non-linear response curve.

Brightness is a perceptual attribute, it does not have a "physical" measure. However some color appearance models do have a value, usualy denoted as "Q" for perceived brightness, which is different than perceived lightness.

Luma (Y´ prime) is a gamma encoded, weighted signal used in some video encodings (Y´I´Q´). It is not to be confused with linear luminance.

Gamma or transfer curve (TRC) is a curve that is often similar to the perceptual curve, and is commonly applied to image data for storage or broadcast to reduce perceived noise and/or improve data utilization (and related reasons).

To determine perceived lightness, first convert gamma encoded R´G´B´ image values to linear luminance (L or Y ) and then to non-linear perceived lightness (L*)

TO FIND LUMINANCE:

...Because apparently it was lost somewhere...

Step One:

Convert all sRGB 8 bit integer values to decimal 0.0-1.0

  vR = sR / 255;
  vG = sG / 255;
  vB = sB / 255;

Step Two:

Convert a gamma encoded RGB to a linear value. sRGB (computer standard) for instance requires a power curve of approximately V^2.2, though the "accurate" transform is:

Where V´ is the gamma-encoded R, G, or B channel of sRGB.
Pseudocode:

function sRGBtoLin(colorChannel) {
        // Send this function a decimal sRGB gamma encoded color value
        // between 0.0 and 1.0, and it returns a linearized value.

    if ( colorChannel <= 0.04045 ) {
            return colorChannel / 12.92;
        } else {
            return pow((( colorChannel + 0.055)/1.055),2.4));
        }
    }

Step Three:

To find Luminance (Y) apply the standard coefficients for sRGB:

Pseudocode using above functions:

Y = (0.2126 * sRGBtoLin(vR) + 0.7152 * sRGBtoLin(vG) + 0.0722 * sRGBtoLin(vB))

TO FIND PERCEIVED LIGHTNESS:

Step Four:

Take luminance Y from above, and transform to L*

Pseudocode:

function YtoLstar(Y) {
        // Send this function a luminance value between 0.0 and 1.0,
        // and it returns L* which is "perceptual lightness"

    if ( Y <= (216/24389) {       // The CIE standard states 0.008856 but 216/24389 is the intent for 0.008856451679036
            return Y * (24389/27);  // The CIE standard states 903.3, but 24389/27 is the intent, making 903.296296296296296
        } else {
            return pow(Y,(1/3)) * 116 - 16;
        }
    }

L* is a value from 0 (black) to 100 (white) where 50 is the perceptual "middle grey". L* = 50 is the equivalent of Y = 18.4, or in other words an 18% grey card, representing the middle of a photographic exposure (Ansel Adams zone V).

As Nayan said the Path has to updated properly in my case the apache-maven was installed in C:\apache-maven and settings.xml was found inside C:\apache-maven\conf\settings.xml

if this doesn't work go to your local repos
in my case C:\Users\<<"name">>.m2\
and search for .lastUpdated and delete them
then build the maven

I found James Wald's answer the closest to my solution, except instead of "File->Import->General->Existing Projects into Workspace" (which did not work for me at all) I used "File->Import->Android->Existing Android Code Into Workspace". I am using Helios, maybe your version of Eclipse does not have this quirk.

Use formaction attribute inside the button

PS! It only works if your button type="submit"

<button type="submit" formaction="www.youraddress.com">Submit</button>

You can select on any attribute and its value by using the attribute selector [attributename=optionalvalue], so in your case you can select the option and set the selected attribute.

$("div.id_100 > select > option[value=" + value + "]").prop("selected",true);

Where value is the value you wish to select by.

If you need to removed any prior selected values, as would be the case if this is used multiple times you'd need to change it slightly so as to first remove the selected attribute

$("div.id_100 option:selected").prop("selected",false);
$("div.id_100 option[value=" + value + "]")
        .prop("selected",true);

You can use a binding source to bind to with your datagridview. Set your class or list of data. Set a bindingsource.datasource equal to that. Set the datasource of your datagridview to your bindingsource.

If its in a landscape then you will be needing more width and less height! That's just what all websites have.

Lets go with a basic first then the rest!

The basic CSS:

By CSS you can do this,

#body {
width: 100%;
height: 100%;
}

Here you are using a div with id body, as:

<body>
  <div id="body>
    all the text would go here!
  </div>
</body>

Then you can have a web page with 100% height and width.

What if he tries to resize the window?

The issues pops up, what if he tries to resize the window? Then all the elements inside #body would try to mess up the UI. For that you can write this:

#body {
height: 100%;
width: 100%;
}

And just add min-height max-height min-width and max-width.

This way, the page element would stay at the place they were at the page load.

Using JavaScript:

Using JavaScript, you can control the UI, use jQuery as:

$('#body').css('min-height', '100%');

And all other remaining CSS properties, and JS will take care of the User Interface when the user is trying to resize the window.

How to not add scroll to the web page:

If you are not trying to add a scroll, then you can use this JS

$('#body').css('min-height', screen.height); // or anyother like window.height

This way, the document will get a new height whenever the user would load the page.

Second option is better, because when users would have different screen resolutions they would want a CSS or Style sheet created for their own screen. Not for others!

Tip: So try using JS to find current Screen size and edit the page! :)

Try something like this

var d = new Date,
    dformat = [d.getMonth()+1,
               d.getDate(),
               d.getFullYear()].join('/')+' '+
              [d.getHours(),
               d.getMinutes(),
               d.getSeconds()].join(':');

If you want leading zero's for values < 10, use this number extension

Number.prototype.padLeft = function(base,chr){
    var  len = (String(base || 10).length - String(this).length)+1;
    return len > 0? new Array(len).join(chr || '0')+this : this;
}
// usage
//=> 3..padLeft() => '03'
//=> 3..padLeft(100,'-') => '--3' 

Applied to the previous code:

var d = new Date,
    dformat = [(d.getMonth()+1).padLeft(),
               d.getDate().padLeft(),
               d.getFullYear()].join('/') +' ' +
              [d.getHours().padLeft(),
               d.getMinutes().padLeft(),
               d.getSeconds().padLeft()].join(':');
//=> dformat => '05/17/2012 10:52:21'

See this code in jsfiddle

[edit 2019] Using ES20xx, you can use a template literal and the new padStart string extension.

var dt = new Date();_x000D_
_x000D_
console.log(`${_x000D_
    (dt.getMonth()+1).toString().padStart(2, '0')}/${_x000D_
    dt.getDate().toString().padStart(2, '0')}/${_x000D_
    dt.getFullYear().toString().padStart(4, '0')} ${_x000D_
    dt.getHours().toString().padStart(2, '0')}:${_x000D_
    dt.getMinutes().toString().padStart(2, '0')}:${_x000D_
    dt.getSeconds().toString().padStart(2, '0')}`_x000D_
);

Taking a cue from @Mikel Yang, I found out that instead of deleting the ~/.gradle/wrapper/dists/ folder (which will means downloading the gradle files for different apps on my Android Studio), I decided to change the gradle.wrapper.properties file to any latest gradle --all.zip. So

Find 'gradle-wrapper.properties' in root project

distributionUrl=https\://services.gradle.org/distributions/gradle-{lastest}-all.zip

this way l get to save some data and time.

When you're in a detached head situation and created new files, first make sure that these new files are added to the index, for example with:

git add .

But if you've only changed or deleted existing files, you can add (-a) and commit with a message (-m) at the the same time via:

git commit -a -m "my adjustment message"

Then you can simply create a new branch with your current state with:

git checkout -b new_branch_name

You'll have a new branch and all your adjustments will be there in that new branch. You can then continue to push to the remote and/or checkout/pull/merge as you please.

If you are using windows, just run .\Scripts\activate. Mind that the backslash plays the trick!

Replace

volume = (4 / 3) Math.PI * Math.pow(radius, 3);

With:

volume = (4 * Math.PI * Math.pow(radius, 3)) / 3;

In addition to Adam Rosenfield's answer, I would like to add that ByteBuffer.array() returns the buffer's underlying byte array, which is not necessarily "trimmed" up to the last character. Extra manipulation will be needed, such as the ones mentioned in this answer; in particular:

byte[] b = new byte[bb.remaining()]
bb.get(b);

Additional Solution: use Restul api wrapper libraries written in Java / python / Ruby - An object oriented wrappers which aim to provide a more conventionally way of controlling a Jenkins server.

For documentation and links: Remote Access API

Set the ReadOnly attribute to true.

Or if you want the combobox to appear and display the list of "available" values, you could handle the ValueChanged event and force it back to your immutable value.

You seem to be aware already, but I'll just restate it anyway; It's a bad sign, if you need to test protected methods. The aim of a unit test, is to test the interface of a class, and protected methods are implementation details. That said, there are cases where it makes sense. If you use inheritance, you can see a superclass as providing an interface for the subclass. So here, you would have to test the protected method (But never a private one). The solution to this, is to create a subclass for testing purpose, and use this to expose the methods. Eg.:

class Foo {
  protected function stuff() {
    // secret stuff, you want to test
  }
}

class SubFoo extends Foo {
  public function exposedStuff() {
    return $this->stuff();
  }
}

Note that you can always replace inheritance with composition. When testing code, it's usually a lot easier to deal with code that uses this pattern, so you may want to consider that option.

UPDATE

This answer was submitted when Angular 2 was still in alpha and many of the features were unavailable / undocumented. While the below will still work, this method is now entirely outdated. I strongly recommend the accepted answer over the below.

Original Answer

Yes in fact it is, however you will want to make sure that it is scoped correctly. For this I've used a property to ensure that this means what I want it to.

@Component({
  ...
  template: '<child [myCallback]="theBoundCallback"></child>',
  directives: [ChildComponent]
})
export class ParentComponent{
  public theBoundCallback: Function;

  public ngOnInit(){
    this.theBoundCallback = this.theCallback.bind(this);
  }

  public theCallback(){
    ...
  }
}

@Component({...})
export class ChildComponent{
  //This will be bound to the ParentComponent.theCallback
  @Input()
  public myCallback: Function; 
  ...
}

    //Array is shorted and if writing in C/C++ think of XOR implementations in java as follows.
                    int num=-1;
    for (int i=1; i<=100; i++){
        num =2*i;
        if(arr[num]==0){
         System.out.println("index: "+i+" Array position: "+ num);      
         break;
        }
        else if(arr[num-1]==0){
         System.out.println("index: "+i+ " Array position: "+ (num-1)); 
         break;             
        }           
    }// use Rabbit and tortoise race, move the dangling index faster, 
     //learnt from Alogithimica, Ameerpet, hyderbad**

Found this on a different forum

If you're wondering why that leading zero is important, it's because permissions are set as an octal integer, and Python automagically treats any integer with a leading zero as octal. So os.chmod("file", 484) (in decimal) would give the same result.

What you are doing is passing 664 which in octal is 1230

In your case you would need

os.chmod("/tmp/test_file", 436)

[Update] Note, for Python 3 you have prefix with 0o (zero oh). E.G, 0o666

So for a lot of the issues here, it seems that people were already running psql and had to remove postmaster.pid. However, I did not have that issue as I never even had postgres installed in my system properly.

Here's a solution that worked for me in MAC OSX Yosemite

1. I went to http://postgresapp.com/ and downloaded the app.
2. I moved the app to Application/ directory
3. I added it to $PATH by adding this to .bashrc or .bash_profile or .zshrc : export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/latest/bin
4. I ran the postgres from the Applications directory and ran the command again and it worked.

Hope this helps! Toodles!

Also, this answer helped me the most: https://stackoverflow.com/a/21503349/3173748

You are using some sort of revision control, right? Then it should be quite simple to restore to the commit before you added the gem, or revert the one where you added it if you have several revisions after that you wish to keep.

See ReceivedTime Property

http://msdn.microsoft.com/en-us/library/office/aa171873(v=office.11).aspx

You added another \ to the end of C:\Temp\ in the SaveAs File line. Could be a problem. Do a test first before adding a path separator.

dateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd H-mm")  
saveFolder = "C:\Temp"

You have not set objAtt so there is no need for "Set objAtt = Nothing". If there was it would be just before End Sub not in the loop.

Public Sub saveAttachtoDisk (itm As Outlook.MailItem) 
    Dim objAtt As Outlook.Attachment 
    Dim saveFolder As String Dim dateFormat
    dateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd H-mm")  saveFolder = "C:\Temp"
    For Each objAtt In itm.Attachments
        objAtt.SaveAsFile saveFolder & "\" & dateFormat & objAtt.DisplayName
    Next
End Sub

JOIN t2 ON (t2.id = t1.id AND t2.date = t1.date)

I tried many formats, but only that worked:

select /*+INDEX(e,dept_idx)*/ * from emp e;

First, is 40 collisions for 130 words hashed to 0..99 bad? You can't expect perfect hashing if you are not taking steps specifically for it to happen. An ordinary hash function won't have fewer collisions than a random generator most of the time.

A hash function with a good reputation is MurmurHash3.

Finally, regarding the size of the hash table, it really depends what kind of hash table you have in mind, especially, whether buckets are extensible or one-slot. If buckets are extensible, again there is a choice: you choose the average bucket length for the memory/speed constraints that you have.

While none of these answers worked for me, I was able to fix the issue using the following command.

git fetch origin

This did a trick for me.

Answer from 2019:

1. For number of clones you can use https://developer.github.com/v3/repos/traffic/#clones (but be aware that it returns count only for last 14 days)
2. For get downloads number of your assets (files attached to the release), you can use https://developer.github.com/v3/repos/releases/#get-a-single-release (exactly "download_count" property of the items of assets list in response)

you can update your npm package by using this command:

npm install <package_name>@<version_number>

example: npm install [email protected]

I don't know what kind of homework this is, but most probably the teacher doesn't want an answer where you just call a "magical" existing function (even though that's the recommended way to do it), but he wants to see if you can implement this by your own.

Back in the days, my teacher used to say something like "I want to see if you can program by yourself, not if you can find it in the system." Well, how wrong he was ;) ..

Anyway, if your teacher is the same, here is the hard way to do it..

std::string LongToString(long value)
{
  std::string output;
  std::string sign;

  if(value < 0)
  {
    sign + "-";
    value = -value;
  }

  while(output.empty() || (value > 0))
  {
    output.push_front(value % 10 + '0')
    value /= 10;
  }

  return sign + output;
}

You could argue that using std::string is not "the hard way", but I guess what counts in the actual agorithm.

I finally got this working.

I think the fact that our project had two different versions of the commons-httpclient jar wasn't helping. Once I sorted that out I found you can do two things...

In code you can put the following:

HttpComponentsClientHttpRequestFactory rf =
    (HttpComponentsClientHttpRequestFactory) restTemplate.getRequestFactory();
rf.setReadTimeout(1 * 1000);
rf.setConnectTimeout(1 * 1000);

The first time this code is called it will set the timeout for the HttpComponentsClientHttpRequestFactory class used by the RestTemplate. Therefore, all subsequent calls made by RestTemplate will use the timeout settings defined above.

Or the better option is to do this:

<bean id="RestOperations" class="org.springframework.web.client.RestTemplate">
    <constructor-arg>
        <bean class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">
            <property name="readTimeout" value="${application.urlReadTimeout}" />
            <property name="connectTimeout" value="${application.urlConnectionTimeout}" />
        </bean>
    </constructor-arg>
</bean>

Where I use the RestOperations interface in my code and get the timeout values from a properties file.

Could you try something like this for example I think what you are wanting to utilize is the port.ReadExisting() Method

 using System;
 using System.IO.Ports;

 class SerialPortProgram 
 { 
  // Create the serial port with basic settings 
    private SerialPort port = new   SerialPort("COM1",
      9600, Parity.None, 8, StopBits.One); 
    [STAThread] 
    static void Main(string[] args) 
    { 
      // Instatiate this 
      SerialPortProgram(); 
    } 

    private static void SerialPortProgram() 
    { 
        Console.WriteLine("Incoming Data:");
         // Attach a method to be called when there
         // is data waiting in the port's buffer 
        port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); 
        // Begin communications 
        port.Open(); 
        // Enter an application loop to keep this thread alive 
        Console.ReadLine();
     } 

    private void port_DataReceived(object sender, SerialDataReceivedEventArgs e) 
    { 
       // Show all the incoming data in the port's buffer
       Console.WriteLine(port.ReadExisting()); 
    } 
}

Or is you want to do it based on what you were trying to do , you can try this

public class MySerialReader : IDisposable
{
  private SerialPort serialPort;
  private Queue<byte> recievedData = new Queue<byte>();

  public MySerialReader()
  {
    serialPort = new SerialPort();
    serialPort.Open();
    serialPort.DataReceived += serialPort_DataReceived;
  }

  void serialPort_DataReceived(object s, SerialDataReceivedEventArgs e)
  {
    byte[] data = new byte[serialPort.BytesToRead];
    serialPort.Read(data, 0, data.Length);
    data.ToList().ForEach(b => recievedData.Enqueue(b));
    processData();
  }

  void processData()

I had this problem with version 6.7.4 and resolved it by installing version 6.5.6.

My setup is Win 2008 R2 SP1 Data Center edition, SQL Server 2008 R2 with Business Intelligence Development Studio (VS2008). Very basic install.

When I was installing 6.7.4, i could not even see the MySQL provider as a choice. However, when i looked into the machine.config file, I saw references for MySQL role provider etc, but no entry was added in the .

All these answers seem a bit complicated. I would just subtract 0.5 from your number and use toFixed().

What you have seems to be a string incorrectly decoded from another encoding, likely code page 1252, which is US Windows default. Here's how to reverse, assuming no other loss. One loss not immediately apparent is the non-breaking space (U+00A0) at the end of your string that is not displayed. Of course it would be better to read the data source correctly in the first place, but perhaps the data source was stored incorrectly to begin with.

using System;
using System.Text;

class Program
{
    static void Main(string[] args)
    {
        string junk = "déjÃ\xa0";  // Bad Unicode string

        // Turn string back to bytes using the original, incorrect encoding.
        byte[] bytes = Encoding.GetEncoding(1252).GetBytes(junk);

        // Use the correct encoding this time to convert back to a string.
        string good = Encoding.UTF8.GetString(bytes);
        Console.WriteLine(good);
    }
}

Result:

In mysql the SET clause needs to come after the JOIN. Example:

UPDATE e
    LEFT JOIN a ON a.id = e.aid
    SET e.id = 2
    WHERE  
        e.type = 'user' AND
        a.country = 'US';

I had the same problem and this is my solution. I had the following code:

se.GiftDescription = rs.getString(1);
se.GiftAmount = rs.getInt(2);

And I changed it to:

se.GiftDescription = rs.getString("DESCRIPTION");
se.GiftAmount = rs.getInt("AMOUNT");

And the problem was, after I restarted my PC, the column positions changed. That's why I got this error.

Just change + to -:

str = str.replace(/[^a-z0-9-]/g, "");

You can read it as:

1. [^ ]: match NOT from the set
2. [^a-z0-9-]: match if not a-z, 0-9 or -
3. / /g: do global match

I also don't like using a function to handle a property which has been resolved again and again in every controller and service. Seem I'm not alone :D

Don't tried to get result with a promise as a variable, of course no way. But I found and use a solution below to access to the result as a property.

Firstly, write result to a property of your service:

app.factory('your_factory',function(){
    var theParentIdResult = null;
    var factoryReturn = {  
        theParentId: theParentIdResult,
        addSiteParentId : addSiteParentId
    };
    return factoryReturn;
    function addSiteParentId(nodeId) {   
         var theParentId = 'a';
         var parentId = relationsManagerResource.GetParentId(nodeId)
             .then(function(response){                               
                 factoryReturn.theParentIdResult = response.data;
                 console.log(theParentId);  // #1
             });                    
    }        
})

Now, we just need to ensure that method addSiteParentId always be resolved before we accessed to property theParentId. We can achieve this by using some ways.

• Use resolve in router method:

  resolve: {
      parentId: function (your_factory) {
           your_factory.addSiteParentId();
      }
  }
  

then in controller and other services used in your router, just call your_factory.theParentId to get your property. Referce here for more information: http://odetocode.com/blogs/scott/archive/2014/05/20/using-resolve-in-angularjs-routes.aspx

• Use run method of app to resolve your service.

  app.run(function (your_factory) { your_factory.addSiteParentId(); })
  

• Inject it in the first controller or services of the controller. In the controller we can call all required init services. Then all remain controllers as children of main controller can be accessed to this property normally as you want.

Chose your ways depend on your context depend on scope of your variable and reading frequency of your variable.

You can use the following CSS to center the form (note that it is important to set the width to something that isn´t 'auto' for this to work):

form {
   margin-left:auto;
   margin-right:auto;
   width:100px;
}

Is there any particular reason that you need to use find? You can just use ls to find files that match a pattern in a directory.

ls /dev/abc-*

If you do need to use find, you can use the -maxdepth 1 switch to only apply to the specified directory.

here is a good way to explain it:

there are two forms of the URI

1 - Builder(ready to be modified, not ready to be used)

2 - Built(not ready to be modified, ready to be used )

You can create a builder by

Uri.Builder builder = new Uri.Builder();

this gonna return a Builder ready to be modified like this:-

builder.scheme("https");
builder.authority("api.github.com");
builder.appendPath("search");
builder.appendPath("repositories");
builder.appendQueryParameter(PARAMETER_QUERY,parameterValue);

but to use it you have to build it first

retrun builder.build();

or however you gonna use it. and then you have built that is already built for you, ready to use but cannot be modified.

Uri built = Uri.parse("your URI goes here");

this is ready to use but if you want to modify it you need to buildUpon()

Uri built = Uri.parse("Your URI goes here")
           .buildUpon(); //now it's ready to be modified
           .buildUpon()
           .appendQueryParameter(QUERY_PARAMATER, parameterValue) 
           //any modification you want to make goes here
           .build(); // you have to build it back cause you are storing it 
                     // as Uri not Uri.builder

now every time you want to modify it you need to buildUpon() and in the end build().

so Uri.Builder is a Builder type that store a Builder in it. Uri is a Built type that store an already built URI in it.

new Uri.Builder(); rerurns a Builder. Uri.parse("your URI goes here") returns a Built.

and with build() you can change it from Builder to Built. buildUpon() you can change it from Built to Builder. Here is what you can do

Uri.Builder builder = Uri.parse("URL").buildUpon();
// here you created a builder, made an already built URI with Uri.parse
// and then change it to builder with buildUpon();
Uri built = builder.build();
//when you want to change your URI, change Builder 
//when you want to use your URI, use Built

and also the opposite:-

Uri built = new Uri.Builder().build();
// here you created a reference to a built URI
// made a builder with new Uri.Builder() and then change it to a built with 
// built();
Uri.Builder builder = built.buildUpon();

hope my answer helped :) <3

To access the tomcat manager from different machine you have to follow bellow steps:

1. Update conf/tomcat-users.xml file with user and some roles:

<role rolename="manager-gui"/>
 <role rolename="manager-script"/>
 <role rolename="manager-jmx"/>
 <role rolename="manager-status"/>
 <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status"/>

Here admin user is assigning roles="manager-gui,manager-script,manager-jmx,manager-status".

Here tomcat user and password is : admin

2. Update webapps/manager/META-INF/context.xml file (Allowing IP address):

Default configuration:

<Context antiResourceLocking="false" privileged="true" >
  
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
  
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>

Here in Valve it is allowing only local machine IP start with 127.\d+.\d+.\d+ .

2.a : Allow specefic IP:

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|YOUR.IP.ADDRESS.HERE" />

Here you just replace |YOUR.IP.ADDRESS.HERE with your IP address

2.b : Allow all IP:

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow=".*" />

Here using allow=".*" you are allowing all IP.

Thanks :)

This works on GitHub:

[](Comment text goes here)

The resulting HTML looks like:

<a href="Comment%20text%20goes%20here"></a>

Which is basically an empty link. Obviously you can read that in the source of the rendered text, but you can do that on GitHub anyway.

In my case, it's because we tried to post a notification without specifying the NotificationChannel:

public static final String NOTIFICATION_CHANNEL_ID_SERVICE = "com.mypackage.service";
public static final String NOTIFICATION_CHANNEL_ID_TASK = "com.mypackage.download_info";

public void initChannel(){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        nm.createNotificationChannel(new NotificationChannel(NOTIFICATION_CHANNEL_ID_SERVICE, "App Service", NotificationManager.IMPORTANCE_DEFAULT));
        nm.createNotificationChannel(new NotificationChannel(NOTIFICATION_CHANNEL_ID_INFO, "Download Info", NotificationManager.IMPORTANCE_DEFAULT));
    }
}

The best place to put above code is in onCreate() method in the Application class, so that we just need to declare it once for all:

public class App extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        initChannel();
    }
}

After we set this up, we can use notification with the channelId we just specified:

Intent i = new Intent(this, MainActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pi = PendingIntent.getActivity(this, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID_INFO);
            .setContentIntent(pi)
            .setWhen(System.currentTimeMillis())
            .setContentTitle("VirtualBox.exe")
            .setContentText("Download completed")
            .setSmallIcon(R.mipmap.ic_launcher);

Then, we can use it to post a notification:

int notifId = 45;
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
nm.notify(notifId, builder.build());

If you want to use it as foreground service's notification:

startForeground(notifId, builder.build());

Why does response.json return a promise?

Because you receive the response as soon as all headers have arrived. Calling .json() gets you another promise for the body of the http response that is yet to be loaded. See also Why is the response object from JavaScript fetch API a promise?.

Why do I get the value if I return the promise from the then handler?

Because that's how promises work. The ability to return promises from the callback and get them adopted is their most relevant feature, it makes them chainable without nesting.

You can use

fetch(url).then(response => 
    response.json().then(data => ({
        data: data,
        status: response.status
    })
).then(res => {
    console.log(res.status, res.data.title)
}));

or any other of the approaches to access previous promise results in a .then() chain to get the response status after having awaited the json body.

In order to get rid of duplicates, you can group by drinks.id. But that way you'll get only one photo for each drinks.id (which photo you'll get depends on database internal implementation).

Though it is not documented, in case of MySQL, you'll get the photo with lowest id (in my experience I've never seen other behavior).

SELECT name, price, photo 
FROM drinks, drinks_photos 
WHERE drinks.id = drinks_id
GROUP BY drinks.id

Matlab allows you to return multiple values as well as receive them inline.

When you call it, receive individual variables inline:

[array, listp, freep] = initialize(size)

There is a useful behavior for this task which doesn't break MVVM, a Behavior, introduced with Expression Blend 3, to allow the View to hook into commands defined completely within the ViewModel.

This behavior demonstrates a simple technique for allowing the ViewModel to manage the closing events of the View in a Model-View-ViewModel application.

This allows you to hook up a behavior in your View (UserControl) which will provide control over the control's Window, allowing the ViewModel to control whether the window can be closed via standard ICommands.

Most database servers have a COALESCE function, which will return the first argument that is non-null, so the following should do what you want:

SELECT COALESCE(SUM(Price),0) AS TotalPrice
FROM Inventory
WHERE (DateAdded BETWEEN @StartDate AND @EndDate)

Since there seems to be a lot of discussion about

COALESCE/ISNULL will still return NULL if no rows match, try this query you can copy-and-paste into SQL Server directly as-is:

SELECT coalesce(SUM(column_id),0) AS TotalPrice 
FROM sys.columns
WHERE (object_id BETWEEN -1 AND -2)

Note that the where clause excludes all the rows from sys.columns from consideration, but the 'sum' operator still results in a single row being returned that is null, which coalesce fixes to be a single row with a 0.

Try this: for the previous view use this:

navigationController?.popViewController(animated: true)  

pop to root use this code:

navigationController?.popToRootViewController(animated: true) 

you could write an extension method

public static void Fill<T>(this T[] array, T value)
{
  for(int i = 0; i < array.Length; i++) 
  {
     array[i] = value;
  }
}

If you have an Order class, adding a property that references another class in your model, for instance Customer should be enough to let EF know there's a relationship in there:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    public virtual Customer Customer { get; set; }
}

You can always set the FK relation explicitly:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    [ForeignKey("Customer")]
    public string CustomerID { get; set; }
    public virtual Customer Customer { get; set; }
}

The ForeignKeyAttribute constructor takes a string as a parameter: if you place it on a foreign key property it represents the name of the associated navigation property. If you place it on the navigation property it represents the name of the associated foreign key.

What this means is, if you where to place the ForeignKeyAttribute on the Customer property, the attribute would take CustomerID in the constructor:

public string CustomerID { get; set; }
[ForeignKey("CustomerID")]
public virtual Customer Customer { get; set; }

EDIT based on Latest Code You get that error because of this line:

[ForeignKey("Parent")]
public Patient Patient { get; set; }

EF will look for a property called Parent to use it as the Foreign Key enforcer. You can do 2 things:

1) Remove the ForeignKeyAttribute and replace it with the RequiredAttribute to mark the relation as required:

[Required]
public virtual Patient Patient { get; set; }

Decorating a property with the RequiredAttribute also has a nice side effect: The relation in the database is created with ON DELETE CASCADE.

I would also recommend making the property virtual to enable Lazy Loading.

2) Create a property called Parent that will serve as a Foreign Key. In that case it probably makes more sense to call it for instance ParentID (you'll need to change the name in the ForeignKeyAttribute as well):

public int ParentID { get; set; }

In my experience in this case though it works better to have it the other way around:

[ForeignKey("Patient")]
public int ParentID { get; set; }

public virtual Patient Patient { get; set; }

With jQuery, I've found that sometimes using val to clear the value of a textbox has no effect, in those situations I've found that using attr does the job

$('#searchField').attr("value", "");

I wanted my logging information to be sent to stdout because it's easy to tell Amazon's Container service (ECS) to collect stdout and send it to CloudWatch Logs. So to get this working, I added a new stdout entry to my config/logging.php file like so:

    'stdout' => [
        'driver' => 'monolog',
        'handler' => StreamHandler::class,
        'with' => [
            'stream' => 'php://stdout',
        ],
        'level' => 'info',
    ],

Then I simply added 'stdout' as one of the channels in the stack log channel:

    'default' => env('LOG_CHANNEL', 'stack'),

    'stack' => [
        'driver' => 'stack',
        'channels' => ['stdout', 'daily'],
    ],

This way, I still get logs in a file for local development (or even on the instance if you can access it), but more importantly they get sent to the stdout which is saved in CloudWatch Logs.

EDIT: Updated for jQuery 1.8

Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: Added code to make it a jQuery function.

For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
                 '-moz-transform' : 'rotate('+ degrees +'deg)',
                 '-ms-transform' : 'rotate('+ degrees +'deg)',
                 'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.

Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.

Here is a jsFiddle.

If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.

HTML

<div class="rotate">
    <h1>Rotatey text</h1>
</div>

CSS

/* Totally for style */
.rotate {
    background: #F02311;
    color: #FFF;
    width: 200px;
    height: 200px;
    text-align: center;
    font: normal 1em Arial;
    position: relative;
    top: 50px;
    left: 50px;
}

/* The real code */
.rotated {
    -webkit-transform: rotate(45deg);  /* Chrome, Safari 3.1+ */
    -moz-transform: rotate(45deg);  /* Firefox 3.5-15 */
    -ms-transform: rotate(45deg);  /* IE 9 */
    -o-transform: rotate(45deg);  /* Opera 10.50-12.00 */
    transform: rotate(45deg);  /* Firefox 16+, IE 10+, Opera 12.10+ */
}

jQuery

Make sure these are wrapped in $(document).ready

$('.rotate').click(function() {
    $(this).toggleClass('rotated');
});

Custom intervals

var rotation = 0;
$('.rotate').click(function() {
    rotation += 5;
    $(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
                 '-moz-transform' : 'rotate('+ rotation +'deg)',
                 '-ms-transform' : 'rotate('+ rotation +'deg)',
                 'transform' : 'rotate('+ rotation +'deg)'});
});

Use a function like this:

CREATE function [dbo].[list_to_table] (@list varchar(4000))
returns @tab table (item varchar(100))
begin

if CHARINDEX(',',@list) = 0 or CHARINDEX(',',@list) is null
begin
    insert into @tab (item) values (@list);
    return;
end


declare @c_pos int;
declare @n_pos int;
declare @l_pos int;

set @c_pos = 0;
set @n_pos = CHARINDEX(',',@list,@c_pos);

while @n_pos > 0
begin
    insert into @tab (item) values (SUBSTRING(@list,@c_pos+1,@n_pos - @c_pos-1));
    set @c_pos = @n_pos;
    set @l_pos = @n_pos;
    set @n_pos = CHARINDEX(',',@list,@c_pos+1);
end;

insert into @tab (item) values (SUBSTRING(@list,@l_pos+1,4000));

return;
end;

Instead of using like, you make an inner join with the table returned by the function:

select * from table_1 where id in ('a','b','c')

becomes

select * from table_1 a inner join [dbo].[list_to_table] ('a,b,c') b on (a.id = b.item)

In an unindexed 1M record table the second version took about half the time...

If you just call exit in Bash without any parameters, it will return the exit code of the last command. Combined with OR, Bash should only invoke exit, if the previous command fails. But I haven't tested this.

command1 || exit;
command2 || exit;

Bash will also store the exit code of the last command in the variable $?.

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

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

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

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

Original answer

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

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

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

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

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

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

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

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

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

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

After a little more research, I came across iText, a PDF and RTF-file creation API. I think I can use the RTF generation to create a Doc-readable file that can then be edited using Doc and re-saved.

Anyone have any experience with iText, used in this fashion?

I may be a total noob but I had no clue I had to install npm-cli first. I had just assumed I already had it.

Annotation-driven indicates to Spring that it should scan for annotated beans, and to not just rely on XML bean configuration. Component-scan indicates where to look for those beans.

Here's some doc: http://static.springsource.org/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-config-enable

This will give you the time you want (eg: 21:31 PM)

Calendar cal2 = Calendar.getInstance();
cal2.setTime(date2);

A Queue is an interface, which means you cannot construct a Queue directly.

The best option is to construct off a class that already implements the Queue interface, like one of the following: AbstractQueue, ArrayBlockingQueue, ArrayDeque, ConcurrentLinkedQueue, DelayQueue, LinkedBlockingQueue, LinkedList, PriorityBlockingQueue, PriorityQueue, or SynchronousQueue.

An alternative is to write your own class which implements the necessary Queue interface. It is not needed except in those rare cases where you wish to do something special while providing the rest of your program with a Queue.

public class MyQueue<T extends Tree> implements Queue<T> {
   public T element() {
     ... your code to return an element goes here ...
   }

   public boolean offer(T element) {
     ... your code to accept a submission offer goes here ...
   }

   ... etc ...
}

An even less used alternative is to construct an anonymous class that implements Queue. You probably don't want to do this, but it's listed as an option for the sake of covering all the bases.

new Queue<Tree>() {
   public Tree element() {
     ...
   };

   public boolean offer(Tree element) {
     ...
   };
   ...
};

As per documentation:

Run this command to reload the daemon:

sudo systemctl daemon-reload

After this you need to restart the mongod service:

sudo systemctl start mongod

To verify that MongoDB has started, run:

sudo systemctl status mongod

To ensure that MongoDB will start following a system reboot, run:

sudo systemctl enable mongod

You can do it with Linq, as mamoo showed, but the oldies are good too:

var filteredDataTable = dt.Select(@"EmpId > 2
    AND (EmpName <> 'abc' OR EmpName <> 'xyz')
    AND EmpName like '%il%'" );

To download file on flask call. File name is Examples.pdf When I am hitting 127.0.0.1:5000/download it should get download.

Example:

from flask import Flask
from flask import send_file
app = Flask(__name__)

@app.route('/download')
def downloadFile ():
    #For windows you need to use drive name [ex: F:/Example.pdf]
    path = "/Examples.pdf"
    return send_file(path, as_attachment=True)

if __name__ == '__main__':
    app.run(port=5000,debug=True) 

This is because label is an inline element, and is therefore only as big as the text it contains.

The possible is to display your label as a block element like this:

#formItem label {
    display: block;
    text-align: center;
    line-height: 150%;
    font-size: .85em;
}

However, if you want to use the label on the same line with other elements, you either need to set display: inline-block; and give it an explicit width (which doesn't work on most browsers), or you need to wrap it inside a div and do the alignment in the div.

Using a cookie would probably be the best way to do this.

You could have a checkbox for 'Remember me?' and have the form create a cookie to store the //user's login// info. EDIT: User Session Information

To create a cookie, you'll need to process the login form with PHP.

Check, if you're app-project is selected in the drop-down menu next to the debug-button. Sometimes Android Studio just resets this selection...

For me I just noticed that it was my .h archive with a '{'. Maye that can help someone =)

This works a little differently from other answers in that it unselects all options:

$("#baba option").prop("selected", false);

There are indeed global variables in javascript. You can learn more about scopes, which are helpful in this situation.

Your code could look like this:

<script>
    var count = 1;
    function setColor(btn, color) {
        var property = document.getElementById(btn);
        if (count == 0) {
            property.style.backgroundColor = "#FFFFFF"
            count = 1;        
        }
        else {
            property.style.backgroundColor = "#7FFF00"
            count = 0;
        }
    }
</script>

Hope this helps.

private SimpleDateFormat dataFormat = new SimpleDateFormat("dd/MM/yyyy");

    return super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);

I fixed it by uninstalling Android SDK Platform (4.4W) and then reinstalling it. I also restarted Eclipse after the installation.

Dijkstra's algorithm applies more to weighted paths and it sounds like the poster was wanting to find all paths, not just the shortest.

For this application, I'd build a graph (your application sounds like it wouldn't need to be directed) and use your favorite search method. It sounds like you want all paths, not just a guess at the shortest one, so use a simple recursive algorithm of your choice.

The only problem with this is if the graph can be cyclic.

With the connections:

• 1, 2
• 1, 3
• 2, 3
• 2, 4

While looking for a path from 1->4, you could have a cycle of 1 -> 2 -> 3 -> 1.

In that case, then I'd keep a stack as traversing the nodes. Here's a list with the steps for that graph and the resulting stack (sorry for the formatting - no table option):

current node (possible next nodes minus where we came from) [stack]

1. 1 (2, 3) [1]
2. 2 (3, 4) [1, 2]
3. 3 (1) [1, 2, 3]
4. 1 (2, 3) [1, 2, 3, 1] //error - duplicate number on the stack - cycle detected
5. 3 () [1, 2, 3] // back-stepped to node three and popped 1 off the stack. No more nodes to explore from here
6. 2 (4) [1, 2] // back-stepped to node 2 and popped 1 off the stack.
7. 4 () [1, 2, 4] // Target node found - record stack for a path. No more nodes to explore from here
8. 2 () [1, 2] //back-stepped to node 2 and popped 4 off the stack. No more nodes to explore from here
9. 1 (3) [1] //back-stepped to node 1 and popped 2 off the stack.
10. 3 (2) [1, 3]
11. 2 (1, 4) [1, 3, 2]
12. 1 (2, 3) [1, 3, 2, 1] //error - duplicate number on the stack - cycle detected
13. 2 (4) [1, 3, 2] //back-stepped to node 2 and popped 1 off the stack
14. 4 () [1, 3, 2, 4] Target node found - record stack for a path. No more nodes to explore from here
15. 2 () [1, 3, 2] //back-stepped to node 2 and popped 4 off the stack. No more nodes
16. 3 () [1, 3] // back-stepped to node 3 and popped 2 off the stack. No more nodes
17. 1 () [1] // back-stepped to node 1 and popped 3 off the stack. No more nodes
18. Done with 2 recorded paths of [1, 2, 4] and [1, 3, 2, 4]

Most of the answers won't catch it (presumably) if you use <label for="cbId">cb name</label>. This means when you click the label it will check the box instead of directly clicking on the checkbox. (Not exactly the question, but various search results tend to come here)

<div id="OuterDivOrBody">
    <input type="checkbox" id="checkbox1" />
    <label for="checkbox1">Checkbox label</label>
    <br />
    <br />
    The confirm result:
    <input type="text" id="textbox1" />
</div>

In which case you could use:

Earlier versions of jQuery:

$('#OuterDivOrBody').delegate('#checkbox1', 'change', function () {
    // From the other examples
    if (!this.checked) {
        var sure = confirm("Are you sure?");
        this.checked = !sure;
        $('#textbox1').val(sure.toString());
    }
});

JSFiddle example with jQuery 1.6.4

jQuery 1.7+

$('#checkbox1').on('change', function() { 
    // From the other examples
    if (!this.checked) {
        var sure = confirm("Are you sure?");
        this.checked = !sure;
        $('#textbox1').val(sure.toString());
    }
});

I had this problem too. Calling sudo pip install caused Python packages to be installed in the global site-packages diretory and calling pip install just worked fine. So no use sudo in virtualenv.

One approach would be to create a non-constrained (no unique indexes) table to insert all your data into and do a select distinct from that to do your insert into your hundred table.

So high level would be. I assume all three columns are distinct in my example so for step3 change the NOT EXITS join to only join on the unique columns in the hundred table.

1. Create temporary table. See docs here.

   CREATE TEMPORARY TABLE temp_data(name, name_slug, status);
   

2. INSERT Data into temp table.

   INSERT INTO temp_data(name, name_slug, status); 
   

3. Add any indexes to the temp table.

4. Do main table insert.

   INSERT INTO hundred(name, name_slug, status) 
       SELECT DISTINCT name, name_slug, status
       FROM hundred
       WHERE NOT EXISTS (
           SELECT 'X' 
           FROM temp_data
           WHERE 
               temp_data.name          = hundred.name
               AND temp_data.name_slug = hundred.name_slug
               AND temp_data.status    = status
       );
   

Another point to take in consideration is that the new UI for Service Interface will give you much more flexibility on how you want to create your proxy class. For example, it will allow you to map data contracts to existing dlls, if they match (actually this is the default behaviour).

int64_t is typedef you can find that in <stdint.h> in C

You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.

SELECT * FROM <table_name> WHERE id = 1 
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';

If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':

hour ('HH'), minute('MI'), year('YEAR' or 'YYYY'), month('MONTH' or 'MM'), Day ('DD')

you can use range with cells to get the effect you want (but it would be better not to use select if you don't have to)

For n = 1 to 5
range(cells(1,n).entirecolumn,cells(1,n+4).entirecolumn).Select
do sth
next n

One of the important things to take into account is the "zoom" level of your projection (for Google Maps in particular).

As Google explains it:

At zoom level 1, the map consists of 4 256x256 pixels tiles, resulting in a pixel space from 512x512. At zoom level 19, each x and y pixel on the map can be referenced using a value between 0 and 256 * 2^19

( See https://developers.google.com/maps/documentation/javascript/maptypes?hl=en#MapCoordinates)

To factor in the "zoom" value, I recommend the simple and effective deltaLonPerDeltaX and deltaLatPerDeltaY functions below. While x-pixels and longitudes are strictly proportional, this is not the case for y-pixels and latitudes, for which the formula requires the initial latitude.

Regarding jQuery, the following common methods will also remove other constructs such as data and event handlers:

remove()

In addition to the elements themselves, all bound events and jQuery data associated with the elements are removed.

empty()

To avoid memory leaks, jQuery removes other constructs such as data and event handlers from the child elements before removing the elements themselves.

html()

Additionally, jQuery removes other constructs such as data and event handlers from child elements before replacing those elements with the new content.

You'll have to make this separate try blocks:

try:
    code a
except ExplicitException:
    pass

try:
    code b
except ExplicitException:
    try:
        code c
    except ExplicitException:
        try:
            code d
        except ExplicitException:
            pass

This assumes you want to run code c only if code b failed.

If you need to run code c regardless, you need to put the try blocks one after the other:

try:
    code a
except ExplicitException:
    pass

try:
    code b
except ExplicitException:
    pass

try:
    code c
except ExplicitException:
    pass

try:
    code d
except ExplicitException:
    pass

I'm using except ExplicitException here because it is never a good practice to blindly ignore all exceptions. You'll be ignoring MemoryError, KeyboardInterrupt and SystemExit as well otherwise, which you normally do not want to ignore or intercept without some kind of re-raise or conscious reason for handling those.

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

Well this certainly won't be an answer like Matt J's but hopefully it will still be useful.

size_t reverse(size_t n, unsigned int bytes)
{
    __asm__("BSWAP %0" : "=r"(n) : "0"(n));
    n >>= ((sizeof(size_t) - bytes) * 8);
    n = ((n & 0xaaaaaaaaaaaaaaaa) >> 1) | ((n & 0x5555555555555555) << 1);
    n = ((n & 0xcccccccccccccccc) >> 2) | ((n & 0x3333333333333333) << 2);
    n = ((n & 0xf0f0f0f0f0f0f0f0) >> 4) | ((n & 0x0f0f0f0f0f0f0f0f) << 4);
    return n;
}

This is exactly the same idea as Matt's best algorithm except that there's this little instruction called BSWAP which swaps the bytes (not the bits) of a 64-bit number. So b7,b6,b5,b4,b3,b2,b1,b0 becomes b0,b1,b2,b3,b4,b5,b6,b7. Since we are working with a 32-bit number we need to shift our byte-swapped number down 32 bits. This just leaves us with the task of swapping the 8 bits of each byte which is done and voila! we're done.

Timing: on my machine, Matt's algorithm ran in ~0.52 seconds per trial. Mine ran in about 0.42 seconds per trial. 20% faster is not bad I think.

If you're worried about the availability of the instruction BSWAP Wikipedia lists the instruction BSWAP as being added with 80846 which came out in 1989. It should be noted that Wikipedia also states that this instruction only works on 32 bit registers which is clearly not the case on my machine, it very much works only on 64-bit registers.

This method will work equally well for any integral datatype so the method can be generalized trivially by passing the number of bytes desired:

    size_t reverse(size_t n, unsigned int bytes)
    {
        __asm__("BSWAP %0" : "=r"(n) : "0"(n));
        n >>= ((sizeof(size_t) - bytes) * 8);
        n = ((n & 0xaaaaaaaaaaaaaaaa) >> 1) | ((n & 0x5555555555555555) << 1);
        n = ((n & 0xcccccccccccccccc) >> 2) | ((n & 0x3333333333333333) << 2);
        n = ((n & 0xf0f0f0f0f0f0f0f0) >> 4) | ((n & 0x0f0f0f0f0f0f0f0f) << 4);
        return n;
    }

which can then be called like:

    n = reverse(n, sizeof(char));//only reverse 8 bits
    n = reverse(n, sizeof(short));//reverse 16 bits
    n = reverse(n, sizeof(int));//reverse 32 bits
    n = reverse(n, sizeof(size_t));//reverse 64 bits

The compiler should be able to optimize the extra parameter away (assuming the compiler inlines the function) and for the sizeof(size_t) case the right-shift would be removed completely. Note that GCC at least is not able to remove the BSWAP and right-shift if passed sizeof(char).

In my experience the flow is:

• you publish the app as beta in Google Play and create the Google+ community
• invite the tester to the community
• once he has joined, send him the link of the test app in Google Play
• the tester opens the link in the browser (not google play app)
• registers as tester
• in the browser, install the apps to the device (the app will be magically pushed to the device)

I would start with upgrade of CMAKE version.

You can use INCLUDE_DIRECTORIES for header location and LINK_DIRECTORIES + TARGET_LINK_LIBRARIES for libraries

rosbuild_add_executable(kinectueye src/kinect_ueye.cpp)
TARGET_LINK_LIBRARIES(kinectueye lib1 lib2 lib2 ...)

note that lib1 is expanded to liblib1.so (on Linux), so use ln to create appropriate links in case you do not have them

From what I can gather, the model doesn't want to guess whether checked = true or false, I got around this by setting a value attribute on the checkbox element with jQuery before submitting the form like this:

 $('input[type="checkbox"]').each(function () {

 }); 

This way, you don't need a hidden element just to store the value of the checkbox.

The code you show,

(function (msg){alert(msg)});
('SO');

consist of two statements. The first is an expression which yields a function object (which will then be garbage collected because it is not saved). The second is an expression which yields a string. To apply the function to the string, you either need to pass the string as an argument to the function when it is created (which you also show above), or you will need to actually store the function in a variable, so that you can apply it at a later time, at your leisure. Like so:

var f = (function (msg){alert(msg)});
f('SO');

Note that by storing an anonymous function (a lambda function) in a variable, your are effectively giving it a name. Hence you may just as well define a regular function:

function f(msg) {alert(msg)};
f('SO');

                              ) as cond
                where tbl.usr=cond.usr 
                and tbl.adate =cond.adate 
                and tbl.rev =cond.max_rev

For Bootstrap 3 the default radio/button-group structure is :

<div class="btn-group" data-toggle="buttons">
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option1"> Option 1
    </label>
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option2"> Option 2
    </label>
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option3"> Option 3
    </label>
</div>

And you can select the active one like this:

$('.btn-primary').on('click', function(){

@jmp242 - the generic System.Object type does not contain the CloseMainWindow method, but statically casting the System.Diagnostics.Process type when collecting the ProcessList variable works for me. Updated code (from this answer) with this casting (and looping changed to use ForEach-Object) is below.

function Stop-Processes {
    param(
        [parameter(Mandatory=$true)] $processName,
                                     $timeout = 5
    )
    [System.Diagnostics.Process[]]$processList = Get-Process $processName -ErrorAction SilentlyContinue

    ForEach ($Process in $processList) {
        # Try gracefully first
        $Process.CloseMainWindow() | Out-Null
    }

    # Check the 'HasExited' property for each process
    for ($i = 0 ; $i -le $timeout; $i++) {
        $AllHaveExited = $True
        $processList | ForEach-Object {
            If (-NOT $_.HasExited) {
                $AllHaveExited = $False
            }                    
        }
        If ($AllHaveExited -eq $true){
            Return
        }
        Start-Sleep 1
    }
    # If graceful close has failed, loop through 'Stop-Process'
    $processList | ForEach-Object {
        If (Get-Process -ID $_.ID -ErrorAction SilentlyContinue) {
            Stop-Process -Id $_.ID -Force -Verbose
        }
    }
}

You need to use latest/newest

GoogleApiClient Api

Basically what you need to do is:

private GoogleApiClient mGoogleApiClient;
mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(LocationServices.API)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

Then

@Override
    public void onConnected(Bundle connectionHint) {
        mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
                mGoogleApiClient);
        if (mLastLocation != null) {
            mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
            mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
        }
    }

for the most accurate and reliable location. See my post here:

https://stackoverflow.com/a/33599228/2644905

Do not use LocationListener which is not accurate and has delayed response. To be honest this is easier to implement. Also read documentation: https://developers.google.com/android/reference/com/google/android/gms/common/api/GoogleApiClient

I found good answers here, but also found a simpler way.

The button to create the blob and the download link can be combined in one link, as the link element can have an onclick attribute. (The reverse seems not possible, adding a href to a button does not work.)

You can style the link as a button using bootstrap, which is still pure javascript, except for styling.

Combining the button and the download link also reduces code, as fewer of those ugly getElementById calls are needed.

This example needs only one button click to create the text-blob and download it:

<a id="a_btn_writetofile" download="info.txt" href="#" class="btn btn-primary" 
   onclick="exportFile('This is some dummy data.\nAnd some more dummy data.\n', 'a_btn_writetofile')"
>
   Write To File
</a>

<script>
    // URL pointing to the Blob with the file contents
    var objUrl = null;
    // create the blob with file content, and attach the URL to the downloadlink; 
    // NB: link must have the download attribute
    // this method can go to your library
    function exportFile(fileContent, downloadLinkId) {
        // revoke the old object URL to avoid memory leaks.
        if (objUrl !== null) {
            window.URL.revokeObjectURL(objUrl);
        }
        // create the object that contains the file data and that can be referred to with a URL
        var data = new Blob([fileContent], { type: 'text/plain' });
        objUrl = window.URL.createObjectURL(data);
        // attach the object to the download link (styled as button)
        var downloadLinkButton = document.getElementById(downloadLinkId);
        downloadLinkButton.href = objUrl;
    };
</script>

I hope this might be helpful

<script type="text/javascript">_x000D_
 function redirect() {_x000D_
  document.getElementById("formid").submit();_x000D_

Which version of IntelliJ are you using? Note that since last year, IntelliJ exists in two versions:

• Ultimate Edition, which is the complete IDE
• Community Edition, which is free but does not support JavaEE developments.

(see differences here)

In case you are using the Community Edition, you will not be able to manage a Tomcat installation.

In case you are using the Ultimate Edition, you can have a look at:

• The FAQ for Netbeans users (see question How do I configure a web framework for my project?).
• IntelliJ Ultimate edition "Help": Run/Debug Configuration: Tomcat Server

The correct way to create a user in Django is to use the create_user function. This will handle the hashing of the password, etc..

from django.contrib.auth.models import User
user = User.objects.create_user(username='john',
                                 email='[email protected]',
                                 password='glass onion')

df["First season"] = df["First season"].apply(lambda x : 1 if x > 1990 else x)

It is worth noting that if you are returning server side data - you must supply the Data attribute even if there isn't any. It doesn't read the recordsTotal or recordsFiltered but relies on the count of the data object

Try mylist[0][0]. This should return the first character.

Use this:

while IFS= read -r file ; do rm -- "$file" ; done < delete.list

If you need glob expansion you can omit quoting $file:

IFS=""
while read -r file ; do rm -- $file ; done < delete.list

But be warned that file names can contain "problematic" content and I would use the unquoted version. Imagine this pattern in the file

*
*/*
*/*/*

This would delete quite a lot from the current directory! I would encourage you to prepare the delete list in a way that glob patterns aren't required anymore, and then use quoting like in my first example.

why don't you store your values in HTML5 storage objects such as sessionStorage or localStorage, visit HTML5 Storage Doc to get more details. Using this you can store intermediate values temporarily/permanently locally and then access your values later.

To store values for a session:

sessionStorage.getItem('label')
sessionStorage.setItem('label', 'value')

or more permanently:

localStorage.getItem('label')
localStorage.setItem('label', 'value')

So you can store (temporarily) form data between multiple pages using HTML5 storage objects which you can even retain after reload..

There is a way to perform the string search faster. Assumptions: since we are talking about a switch statement, I can assume that the values won't be changing during runtime.

The idea is to use the C stdlib's qsort and bsearch.

I'll be working on xtofl's code.

struct stringcase { char* string; void (*func)(void); };

void funcB1();
void funcAzA();

struct stringcase cases [] = 
{ { "B1", funcB1 }
, { "AzA", funcAzA }
};

struct stringcase work_cases* = NULL;
int work_cases_cnt = 0;

// prepare the data for searching
void prepare() {
  // allocate the work_cases and copy cases values from it to work_cases
  qsort( cases, i, sizeof( struct stringcase ), stringcase_cmp );
}

// comparator function
int stringcase_cmp( const void *p1, const void *p2 )
{
  return strcasecmp( ((struct stringcase*)p1)->string, ((struct stringcase*)p2)->string);
}

// perform the switching
void myswitch( char* token ) {
  struct stringcase val;
  val.string=token;
  void* strptr = bsearch( &val, work_cases, work_cases_cnt, sizeof( struct stringcase), stringcase_cmp );
  if (strptr) {
    struct stringcase* foundVal = (struct stringcase*)strptr;
    (*foundVal->func)();
    return OK;
  }
  return NOT_FOUND;
}

Use any of these functions:

// stop both mic and camera
function stopBothVideoAndAudio(stream) {
    stream.getTracks().forEach(function(track) {
        if (track.readyState == 'live') {
            track.stop();
        }
    });
}

// stop only camera
function stopVideoOnly(stream) {
    stream.getTracks().forEach(function(track) {
        if (track.readyState == 'live' && track.kind === 'video') {
            track.stop();
        }
    });
}

// stop only mic
function stopAudioOnly(stream) {
    stream.getTracks().forEach(function(track) {
        if (track.readyState == 'live' && track.kind === 'audio') {
            track.stop();
        }
    });
}

className={css(styles.mainDiv, 'subContainer')}

This solution is tried and tested in React SPFx.

Also add import statement :

import { css } from 'office-ui-fabric-react/lib/Utilities';

Try using display: inline-block; on the inner div.

#outer {
    width:500px; 
    height:200px; 
    background:#FFCCCC;
    margin:50px auto 0 auto;
    display:block;
}
#inner {
    background:#FFCC33;
    margin:50px 50px 50px 50px;
    padding:10px;
    display:inline-block;
}

You need the full path to the regsvr32 so %windir$\system32\regsvr32 <*.dll>

The OP's script doesn't work in IE 7. With help from SO, here's a script that does:

exec_body_scripts: function(body_el) {
  // Finds and executes scripts in a newly added element's body.
  // Needed since innerHTML does not run scripts.
  //
  // Argument body_el is an element in the dom.

  function nodeName(elem, name) {
    return elem.nodeName && elem.nodeName.toUpperCase() ===
              name.toUpperCase();
  };

  function evalScript(elem) {
    var data = (elem.text || elem.textContent || elem.innerHTML || "" ),
        head = document.getElementsByTagName("head")[0] ||
                  document.documentElement,
        script = document.createElement("script");

    script.type = "text/javascript";
    try {
      // doesn't work on ie...
      script.appendChild(document.createTextNode(data));      
    } catch(e) {
      // IE has funky script nodes
      script.text = data;
    }

    head.insertBefore(script, head.firstChild);
    head.removeChild(script);
  };

  // main section of function
  var scripts = [],
      script,
      children_nodes = body_el.childNodes,
      child,
      i;

  for (i = 0; children_nodes[i]; i++) {
    child = children_nodes[i];
    if (nodeName(child, "script" ) &&
      (!child.type || child.type.toLowerCase() === "text/javascript")) {
          scripts.push(child);
      }
  }

  for (i = 0; scripts[i]; i++) {
    script = scripts[i];
    if (script.parentNode) {script.parentNode.removeChild(script);}
    evalScript(scripts[i]);
  }
};

Update: Time marches on and so have our browsers. This technique is no longer recommended and you should use Dan's solution if you do not need to support version of Internet Explorer before 7.

Original solution (now outdated):

This will check if the element is entirely visible in the current viewport:

function elementInViewport(el) {
  var top = el.offsetTop;
  var left = el.offsetLeft;
  var width = el.offsetWidth;
  var height = el.offsetHeight;

  while(el.offsetParent) {
    el = el.offsetParent;
    top += el.offsetTop;
    left += el.offsetLeft;
  }

  return (
    top >= window.pageYOffset &&
    left >= window.pageXOffset &&
    (top + height) <= (window.pageYOffset + window.innerHeight) &&
    (left + width) <= (window.pageXOffset + window.innerWidth)
  );
}

You could modify this simply to determine if any part of the element is visible in the viewport:

function elementInViewport2(el) {
  var top = el.offsetTop;
  var left = el.offsetLeft;
  var width = el.offsetWidth;
  var height = el.offsetHeight;

  while(el.offsetParent) {
    el = el.offsetParent;
    top += el.offsetTop;
    left += el.offsetLeft;
  }

  return (
    top < (window.pageYOffset + window.innerHeight) &&
    left < (window.pageXOffset + window.innerWidth) &&
    (top + height) > window.pageYOffset &&
    (left + width) > window.pageXOffset
  );
}

var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'

Replace it with a reusable NOOP (no operation) function.

// this function does nothing
function noop() {};

function foo() {
    foo = noop; // swap the functions

    // do your thing
}

function bar() {
    bar = noop; // swap the functions

    // do your thing
}

This syntax has changed with the newer Apache HTTPd server, please see upgrade to apache 2.4 doc for full details.

2.2 configuration syntax was

Order deny,allow
Deny from all

2.4 configuration now is

Require all denied

Thus, this 2.2 syntax

order deny,allow
deny from all
allow from 127.0.0.1

Would ne now written

Require local

If you want to change what the x button does or make it so that you cannot close it at all try this.

yourwindow.protocol("WM_DELETE_WINDOW", whatever)

then defy what "whatever" means

def whatever():
    #Replace this with what you want python to do when the user hits the x button

You can also make it so that when you close that window you can call it back like this

yourwindow.withdraw() 

This hides the window but does not close it

yourwindow.deiconify()

This makes the window visible again

Expanding on the answer by @gordon, here's an example of readable syntax and argument passing with shell/command module (these differ from the git module in that there are required but free-form arguments, as noted by @ander)

- name: "release tarball is generated"
  local_action:
    module: shell
    _raw_params: git archive --format zip --output release.zip HEAD
    chdir: "files/clones/webhooks"

For Schema related stuff

Model.column_names         
Model.columns_hash         
Model.columns 

For instance variables/attributes in an AR object

object.attribute_names                    
object.attribute_present?          
object.attributes

For instance methods without inheritance from super class

Model.instance_methods(false)

You can now use the ExpectedException attributes, e.g.

[Test]
[ExpectedException(typeof(InvalidOperationException), 
 ExpectedMessage="You can't do that!"]
public void MethodA_WithNull_ThrowsInvalidOperationException()
{
    MethodA(null);
}

The answer from @KM is good as far as it goes but fails to fully follow up on one of his early bits of advice;

..., ignore compact code, ignore worrying about repeating code, ...

If you are looking to achieve the best performance then you should write a bespoke query for each possible combination of optional criteria. This might sound extreme, and if you have a lot of optional criteria then it might be, but performance is often a trade-off between effort and results. In practice, there might be a common set of parameter combinations that can be targeted with bespoke queries, then a generic query (as per the other answers) for all other combinations.

CREATE PROCEDURE spDoSearch
    @FirstName varchar(25) = null,
    @LastName varchar(25) = null,
    @Title varchar(25) = null
AS
BEGIN

    IF (@FirstName IS NOT NULL AND @LastName IS NULL AND @Title IS NULL)
        -- Search by first name only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            FirstName = @FirstName

    ELSE IF (@FirstName IS NULL AND @LastName IS NOT NULL AND @Title IS NULL)
        -- Search by last name only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            LastName = @LastName

    ELSE IF (@FirstName IS NULL AND @LastName IS NULL AND @Title IS NOT NULL)
        -- Search by title only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            Title = @Title

    ELSE IF (@FirstName IS NOT NULL AND @LastName IS NOT NULL AND @Title IS NULL)
        -- Search by first and last name
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            FirstName = @FirstName
            AND LastName = @LastName

    ELSE
        -- Search by any other combination
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
                (@FirstName IS NULL OR (FirstName = @FirstName))
            AND (@LastName  IS NULL OR (LastName  = @LastName ))
            AND (@Title     IS NULL OR (Title     = @Title    ))

END

The advantage of this approach is that in the common cases handled by bespoke queries the query is as efficient as it can be - there's no impact by the unsupplied criteria. Also, indexes and other performance enhancements can be targeted at specific bespoke queries rather than trying to satisfy all possible situations.

I guess many like me ends up in forums like this when the git problem as described above occoures. However, there are so many causes that may lead to the problem that I just wanna share what caused my troubles for others to learn as I already learned from above.

I have my repos on a Linux NAS from sitecom (Never buy NAS from Sitecom, pleeaaase). I have a repo here that is cloned on many computers but which I suddenly was denied pushing to. Recently I installed a plugin so that my NAS could stand as a squeezebox server.

This server scans for media to share. What I did not know was that, possible because of a bug, the server changes the user and group setting to squeeze:user for all files it looks into. And that is ALL files. Thus altering the rights I had to push.

Server is gone and proper rights settings are re-established and everything works perfectly.

I used

chmod -R g+ws *
chown -R <myuser>:<mygroup> *

Where myuser and mygroup off-course must be replaced with proper settings for your system. try git:git or gituser:gituser or something else you might like.,

Two of the most widely used parsers are Expat and libxml.

If you are okay with using C++, there's Xerces-C++ too.

No you would have to create your own solution. Like using the Observer design pattern or something.

If you have no control over the variable or who is using it, I'm afraid you're doomed. EDIT: Or use Skilldrick's solution!

The default specifier depends upon context.

For classes, and interface declarations, the default is package private. This falls between protected and private, allowing only classes in the same package access. (protected is like this, but also allowing access to subclasses outside of the package.)

class MyClass   // package private
{
   int field;    // package private field

   void calc() {  // package private method

   }
}

For interface members (fields and methods), the default access is public. But note that the interface declaration itself defaults to package private.

interface MyInterface  // package private
{
   int field1;         // static final public

   void method1();     // public abstract
}

If we then have the declaration

public interface MyInterface2 extends MyInterface
{

}

Classes using MyInterface2 can then see field1 and method1 from the super interface, because they are public, even though they cannot see the declaration of MyInterface itself.

sum = sum.add(BigInteger.valueOf(i))

The BigInteger class is immutable, hence you can't change its state. So calling "add" creates a new BigInteger, rather than modifying the current.

A more elegant solution than creating an anonymous function who's sole purpose is to wrap another, is to use es5's bind function. The bind function creates a new function that, when called, has its this keyword set to the provided value, with a given sequence of arguments preceding any provided when the new function is called.

Instead of:

expect(function () { parser.parse(raw, config); } ).toThrow("Parsing is not possible");

Consider:

expect(parser.parse.bind(parser, raw, config)).toThrow("Parsing is not possible");

The bind syntax allows you to test functions with different this values, and in my opinion makes the test more readable. See also: https://stackoverflow.com/a/13233194/1248889

Since this question isn't specific to Java, I would like to add how you can do it in Kotlin:

radio_group_id.setOnCheckedChangeListener({ radioGroup, optionId -> {
        when (optionId) {
            R.id.radio_button_1 -> {
                // do something when radio button 1 is selected
            }
            // add more cases here to handle other buttons in the RadioGroup
        }
    }
})

Here radio_group_id is the assigned android:id of the concerned RadioGroup. To use it this way you would need to import kotlinx.android.synthetic.main.your_layout_name.* in your activity's Kotlin file. Also note that in case the radioGroup lambda parameter is unused, it can be replaced with _ (an underscore) since Kotlin 1.1.
