Use the below function and use days paramater to get the date daysAhead/daysBehind just pass parameter as positive for future date or negative for previous dates:

+ (NSDate *) getDate:(NSDate *)fromDate daysAhead:(NSUInteger)days
{
    NSDateComponents *dateComponents = [[NSDateComponents alloc] init];
    dateComponents.day = days;
    NSCalendar *calendar = [NSCalendar currentCalendar];
    NSDate *previousDate = [calendar dateByAddingComponents:dateComponents
                                                     toDate:fromDate
                                                    options:0];
    [dateComponents release];
    return previousDate;
}

trunc(tran_date) = trunc(sysdate -1)

Try this:

Uncomment the following in php.ini by removing the ";"

;extension=php_pgsql.dll

Use the following code to connect to a postgresql database server:

pg_connect("host=localhost dbname=dbname user=username password=password")
    or die("Can't connect to database".pg_last_error());

If you are using Java 6 or higher you can use wildcards of this form:

java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp

If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:

java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp

There is nothing like lib\*\* or lib\** wildcard for the kind of job you want to be done.

I built a general method for that with following features:

• returning "not modified" if the file hasn't been modified locally, a Status.NOT_MODIFIED is sent to the caller. Uses Apache Commons Lang
• using a file stream object instead of reading the file itself

Here the code:

import org.apache.commons.lang3.time.DateUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

private static final Logger logger = LoggerFactory.getLogger(Utils.class);

@GET
@Path("16x16")
@Produces("image/png")
public Response get16x16PNG(@HeaderParam("If-Modified-Since") String modified) {
    File repositoryFile = new File("c:/temp/myfile.png");
    return returnFile(repositoryFile, modified);
}

/**

 * Sends the file if modified and "not modified" if not modified
 * future work may put each file with a unique id in a separate folder in tomcat
 *   * use that static URL for each file
 *   * if file is modified, URL of file changes
 *   * -> client always fetches correct file 
 * 
 *     method header for calling method public Response getXY(@HeaderParam("If-Modified-Since") String modified) {

 */
public static Response returnFile(File file, String modified) {
    if (!file.exists()) {
        return Response.status(Status.NOT_FOUND).build();
    }

    // do we really need to send the file or can send "not modified"?
    if (modified != null) {
        Date modifiedDate = null;

        // we have to switch the locale to ENGLISH as parseDate parses in the default locale
        Locale old = Locale.getDefault();
        Locale.setDefault(Locale.ENGLISH);
        try {
            modifiedDate = DateUtils.parseDate(modified, org.apache.http.impl.cookie.DateUtils.DEFAULT_PATTERNS);
        } catch (ParseException e) {
            logger.error(e.getMessage(), e);
        }
        Locale.setDefault(old);

        if (modifiedDate != null) {
            // modifiedDate does not carry milliseconds, but fileDate does
            // therefore we have to do a range-based comparison
            // 1000 milliseconds = 1 second
            if (file.lastModified()-modifiedDate.getTime() < DateUtils.MILLIS_PER_SECOND) {
                return Response.status(Status.NOT_MODIFIED).build();
            }
        }
    }        
    // we really need to send the file

    try {
        Date fileDate = new Date(file.lastModified());
        return Response.ok(new FileInputStream(file)).lastModified(fileDate).build();
    } catch (FileNotFoundException e) {
        return Response.status(Status.NOT_FOUND).build();
    }
}

Note that the Locale switching does not seem to be thread-safe. I think, it's better to switch the locale globally. I am not sure about the side-effects though...

In XML, xmlns declares a Namespace. In fact, when you do:

<LinearLayout android:id>
</LinearLayout>

Instead of calling android:id, the xml will use http://schemas.android.com/apk/res/android:id to be unique. Generally this page doesn't exist (it's a URI, not a URL), but sometimes it is a URL that explains the used namespace.

The namespace has pretty much the same uses as the package name in a Java application.

Here is an explanation.

Uniform Resource Identifier (URI)

A Uniform Resource Identifier (URI) is a string of characters which identifies an Internet Resource.

The most common URI is the Uniform Resource Locator (URL) which identifies an Internet domain address. Another, not so common type of URI is the Universal Resource Name (URN).

In our examples we will only use URLs.

You can also use:

    sed -n 's/.*\/\([^\/]\{1,\}\)$/\1/p'

or

    sed -n 's/.*\/\([^\/]*\)$/\1/p'

This is an example of using the :checked pseudo-class to make forms more accessible. The :checked pseudo-class can be used with hidden inputs and their visible labels to build interactive widgets, such as image galleries. I created the snipped for the people that wanna test.

input[type=checkbox] + label {_x000D_
  color: #ccc;_x000D_
  font-style: italic;_x000D_
} _x000D_
input[type=checkbox]:checked + label {_x000D_
  color: #f00;_x000D_
  font-style: normal;_x000D_
} 

<input type="checkbox" id="cb_name" name="cb_name"> _x000D_
<label for="cb_name">CSS is Awesome</label> 

You will not write code into a static block that needs to be invoked anywhere in your program. If the purpose of the code is to be invoked then you must place it in a method.

You can write static initializer blocks to initialize static variables when the class is loaded but this code can be more complex..

A static initializer block looks like a method with no name, no arguments, and no return type. Since you never call it it doesn't need a name. The only time its called is when the virtual machine loads the class.

It is not possible. §2.3 says that "." is an unreserved character and that "URIs that differ in the replacement of an unreserved character with its corresponding percent-encoded US-ASCII octet are equivalent". Therefore, /%2E%2E/ is the same as /../, and that will get normalized away.

(This is a combination of an answer by bobince and a comment by slowpoison.)

The question does not make clear what exactly you want to achieve.

List has the append method, which appends its argument to the list:

>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.append(list_two)
>>> list_one
[1, 2, 3, [4, 5, 6]]

There's also the extend method, which appends items from the list you pass as an argument:

>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.extend(list_two)
>>> list_one
[1, 2, 3, 4, 5, 6]

And of course, there's the insert method which acts similarly to append but allows you to specify the insertion point:

>>> list_one.insert(2, list_two)
>>> list_one
[1, 2, [4, 5, 6], 3, 4, 5, 6]

To extend a list at a specific insertion point you can use list slicing (thanks, @florisla):

>>> l = [1, 2, 3, 4, 5]
>>> l[2:2] = ['a', 'b', 'c']
>>> l
[1, 2, 'a', 'b', 'c', 3, 4, 5]

List slicing is quite flexible as it allows to replace a range of entries in a list with a range of entries from another list:

>>> l = [1, 2, 3, 4, 5]
>>> l[2:4] = ['a', 'b', 'c'][1:3]
>>> l
[1, 2, 'b', 'c', 5]

According to the CI docs (CodeIgniter Email Library)...

If you prefer not to set preferences using the above method, you can instead put them into a config file. Simply create a new file called the email.php, add the $config array in that file. Then save the file at config/email.php and it will be used automatically. You will NOT need to use the $this->email->initialize() function if you save your preferences in a config file.

I was able to get this to work by putting all the settings into application/config/email.php.

$config['useragent'] = 'CodeIgniter';
$config['protocol'] = 'smtp';
//$config['mailpath'] = '/usr/sbin/sendmail';
$config['smtp_host'] = 'ssl://smtp.googlemail.com';
$config['smtp_user'] = '[email protected]';
$config['smtp_pass'] = 'YOURPASSWORDHERE';
$config['smtp_port'] = 465; 
$config['smtp_timeout'] = 5;
$config['wordwrap'] = TRUE;
$config['wrapchars'] = 76;
$config['mailtype'] = 'html';
$config['charset'] = 'utf-8';
$config['validate'] = FALSE;
$config['priority'] = 3;
$config['crlf'] = "\r\n";
$config['newline'] = "\r\n";
$config['bcc_batch_mode'] = FALSE;
$config['bcc_batch_size'] = 200;

Then, in one of the controller methods I have something like:

$this->load->library('email'); // Note: no $config param needed
$this->email->from('[email protected]', '[email protected]');
$this->email->to('[email protected]');
$this->email->subject('Test email from CI and Gmail');
$this->email->message('This is a test.');
$this->email->send();

Also, as Cerebro wrote, I had to uncomment out this line in my php.ini file and restart PHP:

extension=php_openssl.dll

I used a string instead of an array and it seems like my algorithm consumes very less time. I am posting my algorithm here, am I measuring the time correctly?

console.time('process');

var result = []

function swapper(toSwap){
    let start = toSwap[0]
    let end = toSwap.slice(1)
    return end + start
}


function perm(str){
    let i = str.length
    let filling = i - 1

    let buckets = i*filling
    let tmpSwap = ''
    for(let j=0; j<filling; j++){
        if(j===0){
            result.push(str)
        }else{
          if(j === 1){
              tmpSwap = swapper(str.slice(1))
              result.push(str[0]+ tmpSwap)
              if(j === filling-1 && result.length < buckets){
                  perm(swapper(str))
              }

          }else{
              tmpSwap = swapper(tmpSwap)
              result.push(str[0]+ tmpSwap)
              if(j === filling-1 && result.length < buckets){
                  perm(swapper(str))
              }
          }
        }
    }

    if(result.length = buckets){
      return result
    }else{
      return 'something went wrong'
    }

}





console.log(perm('abcdefghijk'))

console.timeEnd('process');

Probably not. While I can't log into the Apple Development site, according to this post you need an intel mac platform.

http://tinleyharrier.blogspot.com/2008/03/iphone-sdk-requirements.html

Plain ES6:

var foo = {
    bar: "Yes"
};

const res = Object.keys(foo).filter(i => foo[i] === 'Yes')

console.log(res)
// ["bar"]

Are you asking how to control what is visible when the soft keyboard opens? You might want to play with the windowSoftInputMode. See developer docs for more discussion.

 INSERT INTO table (a,b) VALUES (1,2), (2,3), (3,4);

http://dev.mysql.com/doc/refman/5.5/en/insert.html

There isn't a built-in "PowerShell" way of running a SQL query. If you have the SQL Server tools installed, you'll get an Invoke-SqlCmd cmdlet.

Because PowerShell is built on .NET, you can use the ADO.NET API to run your queries.

Set your database collation to UTF-8 then apply table collation to database default.

CASE is the answer, but you will need to have a separate case statement for each column you want returned. As long as the WHERE clause is the same, there won't be much benefit separating it out into multiple queries.

Example:

SELECT
    CASE @var
        WHEN 'xyz' THEN col1
        WHEN 'zyx' THEN col2
        ELSE col7
    END,
    CASE @var
        WHEN 'xyz' THEN col2
        WHEN 'zyx' THEN col3
        ELSE col8
    END
FROM Table
...

I'd just like to add to the very helpful answer from Kurt Pfeifle - there is now a Python wrapper for Tabula, and this seems to work very well so far: https://github.com/chezou/tabula-py

This will convert your PDF table to a Pandas data frame. You can also set the area in x,y co-ordinates which is obviously very handy for irregular data.

printf is a fair bit more complicated than that. You have to supply a format string, and then the variables to apply to the format string. If you just supply one variable, C will assume that is the format string and try to print out all the bytes it finds in it until it hits a terminating nul (0x0).

So if you just give it an integer, it will merrily march through memory at the location your integer is stored, dumping whatever garbage is there to the screen, until it happens to come across a byte containing 0.

For a Java programmer, I'd imagine this is a rather rude introduction to C's lack of type checking. Believe me, this is only the tip of the iceberg. This is why, while I applaud your desire to expand your horizons by learning C, I highly suggest you do whatever you can to avoid writing real programs in it.

(This goes for everyone else reading this too.)

As @kirbyfan64sos notes in a comment, /home is NOT your home directory (a.k.a. home folder):

The fact that /home is an absolute, literal path that has no user-specific component provides a clue.

While /home happens to be the parent directory of all user-specific home directories on Linux-based systems, you shouldn't even rely on that, given that this differs across platforms: for instance, the equivalent directory on macOS is /Users.

What all Unix platforms DO have in common are the following ways to navigate to / refer to your home directory:

• Using cd with NO argument changes to your home dir., i.e., makes your home dir. the working directory.
  • e.g.: cd # changes to home dir; e.g., '/home/jdoe'

• Unquoted ~ by itself / unquoted ~/ at the start of a path string represents your home dir. / a path starting at your home dir.; this is referred to as tilde expansion (see man bash)
  • e.g.: echo ~ # outputs, e.g., '/home/jdoe'

• $HOME - as part of either unquoted or preferably a double-quoted string - refers to your home dir. HOME is a predefined, user-specific environment variable:
  • e.g.: cd "$HOME/tmp" # changes to your personal folder for temp. files

Thus, to create the desired folder, you could use:

mkdir "$HOME/bin"  # same as: mkdir ~/bin

Note that most locations outside your home dir. require superuser (root user) privileges in order to create files or directories - that's why you ran into the Permission denied error.

Put this in C2 and copy down

=IF(ISNA(VLOOKUP(A2,$B$2:$B$65535,1,FALSE)),"not in B","")

Then if the value in A isn't in B the cell in column C will say "not in B".

This is one way I know of. With git, there always seems to be more than one way to do it.

git log -p commit1 commit2

Lookarounds can be nested.

So this regex matches "drupal-6.14/" that is not followed by "sites" that is not followed by "/all" or "/default".

Confusing? Using different words, we can say it matches "drupal-6.14/" that is not followed by "sites" unless that is further followed by "/all" or "/default"

Worked liked a charm for me:

matplotlib.rcParams['figure.figsize'] = (20, 10)

gitk <path_to_filename>

Assuming the package "gitk" is already installed.

If it is not installed, do this:

sudo apt-get install gitk

And then try the above command. It is for Linux... It might help Linux users if they want a GUI.

Since the .Rows result is marked as consisting of rows, you can "For Each" it to deal with each row individually, like this:

Function Attendance(rng As Range) As Long
Attendance = 0
For Each rRow In rng.Rows
    If WorksheetFunction.Sum(rRow) > 0 Then
        Attendance = Attendance + 1
    End If
Next
End Function

I use this to check attendance in any of a few categories (different columns) for a list of people (different rows).

(And of course you could use .Columns to do a "For Each" over the columns in the range.)

Using jQuery, for instance, you could do:

var _currentFill = "#f00"; // red
$svg = $("#octocat");
$("#face", $svg).attr('style', "fill:"+_currentFill); })

I provided a coloring book demo as an answer to another stackoverflow question: http://bl.ocks.org/4545199. Tested on Safari, Chrome, and Firefox.

You have two option

1. run in cmd or Terminal

react --version
react-native --version

2. check in the project files, open the Package.json

Of course there IS a way to create files without opening. It's as easy as calling os.mknod("newfile.txt"). The only drawback is that this call requires root privileges on OSX.

In your second example the "map" reference is of type Map, which is an interface implemented by HashMap (and other types of Map). This interface is a contract saying that the object maps keys to values and supports various operations (e.g. put, get). It says nothing about the implementation of the Map (in this case a HashMap).

The second approach is generally preferred as you typically wouldn't want to expose the specific map implementation to methods using the Map or via an API definition.

You want str replace, because performance-wise it's much cheaper and still fits your needs!

$title = str_replace( array( '\'', '"', ',' , ';', '<', '>' ), ' ', $rawtitle);

(Unless this is all about security and sql injection, in that case, I'd rather to go with a POSITIVE list of ALLOWED characters... even better, stick with tested, proven routines.)

Btw, since the OP talked about title-setting: I wouldn't replace special chars with nothing, but with a space. A superficious space is less of a problem than two words glued together...

Just wrap it around then.

<?php        
    if ( ($cart->count_product) > 0) 
    { 
        echo "<div class='my_class'>";
        print $cart->count_product; 
        echo "</div>";
    }

?>

Integer i = map.get(key);
if(i == null)
   i = (aValue)
map.put(key, i + 1);

or

Integer i = map.get(key);
map.put(key, i == null ? newValue : i + 1);

Integer is Primitive data types http://cs.fit.edu/~ryan/java/language/java-data.html, so you need to take it out, make some process, then put it back. if you have a value which is not Primitive data types, you only need to take it out, process it, no need to put it back into the hashmap.

char* str = "HELLO";
char c = str[1];

Keep in mind that arrays and strings in C begin indexing at 0 rather than 1, so "H" is str[0], "E" is str[1], the first "L" is str[2] and so on.

You can do something like this

Session session = app.factory.openSession();
CriteriaBuilder builder = session.getCriteriaBuilder();
CriteriaQuery query = builder.createQuery();
Root<Users> root = query.from(Users.class);
query.select(root.get("firstname"));
String name = session.createQuery(query).getSingleResult();

where you can change "firstname" with the name of the column you want.

GCC compilers always try to compile your program if this is at all possible. However, in some cases, the C and C++ standards specify that certain extensions are forbidden. Conforming compilers such as gcc or g++ must issue a diagnostic when these extensions are encountered. For example, the gcc compiler’s -pedantic option causes gcc to issue warnings in such cases. Using the stricter -pedantic-errors option converts such diagnostic warnings into errors that will cause compilation to fail at such points. Only those non-ISO constructs that are required to be flagged by a conforming compiler will generate warnings or errors.

i accomplished this with the install command on linux:

root@logstash:# myfile=bash_history.log.2021-02-04.gz ; install -v -p -D $myfile /tmp/a/b/$myfile

bash_history.log.2021-02-04.gz -> /tmp/a/b/bash_history.log.2021-02-04.gz

the only downside being the file permissions are changed:

root@logstash:# ls -lh /tmp/a/b/

-rwxr-xr-x 1 root root 914 Fev  4 09:11 bash_history.log.2021-02-04.gz

if you dont mind resetting the permission, you can use:

-g, --group=GROUP   set group ownership, instead of process' current group
-m, --mode=MODE     set permission mode (as in chmod), instead of rwxr-xr-x
-o, --owner=OWNER   set ownership (super-user only)

I got the same use case today(31/07/2018) and found this to be a workaround. It is based on my research and it worked for me. Expectation - To achieve the following in TypeScript:

var myStaticClass = {
    property: 10,
    method: function(){} 
}

I did this:

//MyStaticMembers.ts
namespace MyStaticMembers {
        class MyStaticClass {
           static property: number = 10;
           static myMethod() {...}
        }
        export function Property(): number {
           return MyStaticClass.property;
        }
        export function Method(): void {
           return MyStaticClass.myMethod();
        }
     }

Hence we shall consume it as below:

//app.ts
/// <reference path="MyStaticMembers.ts" />
    console.log(MyStaticMembers.Property);
    MyStaticMembers.Method();

This worked for me. If anyone has other better suggestions please let us all hear it !!! Thanks...

I've had the same problem when running my spring boot application with tomcat7:run

It gives error with the following dependency in maven pom.xml:

    <dependency>

But when I correctly specify it in test scope, it does not give error:

It'll be easier (and more "proper", see below) if you just run your script as

myprogram /path/to/file

Then you can access the path within the script as $1 (for argument #1, similarly $2 is argument #2, etc.)

file="$1"
externalprogram "$file" [other parameters]

Or just

externalprogram "$1" [otherparameters]

If you want to extract the path from something like --file=/path/to/file, that's usually done with the getopts shell function. But that's more complicated than just referencing $1, and besides, switches like --file= are intended to be optional. I'm guessing your script requires a file name to be provided, so it doesn't make sense to pass it in an option.

I just wrote a parser that I called Yay! (Yaml ain't Yamlesque!) which parses Yamlesque, a small subset of YAML. So, if you're looking for a 100% compliant YAML parser for Bash then this isn't it. However, to quote the OP, if you want a structured configuration file which is as easy as possible for a non-technical user to edit that is YAML-like, this may be of interest.

It's inspred by the earlier answer but writes associative arrays (yes, it requires Bash 4.x) instead of basic variables. It does so in a way that allows the data to be parsed without prior knowledge of the keys so that data-driven code can be written.

As well as the key/value array elements, each array has a keys array containing a list of key names, a children array containing names of child arrays and a parent key that refers to its parent.

This is an example of Yamlesque:

root_key1: this is value one
root_key2: "this is value two"

drink:
  state: liquid
  coffee:
    best_served: hot
    colour: brown
  orange_juice:
    best_served: cold
    colour: orange

food:
  state: solid
  apple_pie:
    best_served: warm

root_key_3: this is value three

Here is an example showing how to use it:

#!/bin/bash
# An example showing how to use Yay

. /usr/lib/yay

# helper to get array value at key
value() { eval echo \${$1[$2]}; }

# print a data collection
print_collection() {
  for k in $(value $1 keys)
  do
    echo "$2$k = $(value $1 $k)"
  done

  for c in $(value $1 children)
  do
    echo -e "$2$c\n$2{"
    print_collection $c "  $2"
    echo "$2}"
  done
}

yay example
print_collection example

which outputs:

root_key1 = this is value one
root_key2 = this is value two
root_key_3 = this is value three
example_drink
{
  state = liquid
  example_coffee
  {
    best_served = hot
    colour = brown
  }
  example_orange_juice
  {
    best_served = cold
    colour = orange
  }
}
example_food
{
  state = solid
  example_apple_pie
  {
    best_served = warm
  }
}

And here is the parser:

yay_parse() {

   # find input file
   for f in "$1" "$1.yay" "$1.yml"
   do
     [[ -f "$f" ]] && input="$f" && break
   done
   [[ -z "$input" ]] && exit 1

   # use given dataset prefix or imply from file name
   [[ -n "$2" ]] && local prefix="$2" || {
     local prefix=$(basename "$input"); prefix=${prefix%.*}
   }

   echo "declare -g -A $prefix;"

   local s='[[:space:]]*' w='[a-zA-Z0-9_]*' fs=$(echo @|tr @ '\034')
   sed -n -e "s|^\($s\)\($w\)$s:$s\"\(.*\)\"$s\$|\1$fs\2$fs\3|p" \
          -e "s|^\($s\)\($w\)$s:$s\(.*\)$s\$|\1$fs\2$fs\3|p" "$input" |
   awk -F$fs '{
      indent       = length($1)/2;
      key          = $2;
      value        = $3;

      # No prefix or parent for the top level (indent zero)
      root_prefix  = "'$prefix'_";
      if (indent ==0 ) {
        prefix = "";          parent_key = "'$prefix'";
      } else {
        prefix = root_prefix; parent_key = keys[indent-1];
      }

      keys[indent] = key;

      # remove keys left behind if prior row was indented more than this row
      for (i in keys) {if (i > indent) {delete keys[i]}}

      if (length(value) > 0) {
         # value
         printf("%s%s[%s]=\"%s\";\n", prefix, parent_key , key, value);
         printf("%s%s[keys]+=\" %s\";\n", prefix, parent_key , key);
      } else {
         # collection
         printf("%s%s[children]+=\" %s%s\";\n", prefix, parent_key , root_prefix, key);
         printf("declare -g -A %s%s;\n", root_prefix, key);
         printf("%s%s[parent]=\"%s%s\";\n", root_prefix, key, prefix, parent_key);
      }
   }'
}

# helper to load yay data file
yay() { eval $(yay_parse "$@"); }

There is some documentation in the linked source file and below is a short explanation of what the code does.

The yay_parse function first locates the input file or exits with an exit status of 1. Next, it determines the dataset prefix, either explicitly specified or derived from the file name.

It writes valid bash commands to its standard output that, if executed, define arrays representing the contents of the input data file. The first of these defines the top-level array:

echo "declare -g -A $prefix;"

Note that array declarations are associative (-A) which is a feature of Bash version 4. Declarations are also global (-g) so they can be executed in a function but be available to the global scope like the yay helper:

yay() { eval $(yay_parse "$@"); }

The input data is initially processed with sed. It drops lines that don't match the Yamlesque format specification before delimiting the valid Yamlesque fields with an ASCII File Separator character and removing any double-quotes surrounding the value field.

 local s='[[:space:]]*' w='[a-zA-Z0-9_]*' fs=$(echo @|tr @ '\034')
 sed -n -e "s|^\($s\)\($w\)$s:$s\"\(.*\)\"$s\$|\1$fs\2$fs\3|p" \
        -e "s|^\($s\)\($w\)$s:$s\(.*\)$s\$|\1$fs\2$fs\3|p" "$input" |

The two expressions are similar; they differ only because the first one picks out quoted values where as the second one picks out unquoted ones.

The File Separator (28/hex 12/octal 034) is used because, as a non-printable character, it is unlikely to be in the input data.

The result is piped into awk which processes its input one line at a time. It uses the FS character to assign each field to a variable:

indent       = length($1)/2;
key          = $2;
value        = $3;

All lines have an indent (possibly zero) and a key but they don't all have a value. It computes an indent level for the line dividing the length of the first field, which contains the leading whitespace, by two. The top level items without any indent are at indent level zero.

Next, it works out what prefix to use for the current item. This is what gets added to a key name to make an array name. There's a root_prefix for the top-level array which is defined as the data set name and an underscore:

root_prefix  = "'$prefix'_";
if (indent ==0 ) {
  prefix = "";          parent_key = "'$prefix'";
} else {
  prefix = root_prefix; parent_key = keys[indent-1];
}

The parent_key is the key at the indent level above the current line's indent level and represents the collection that the current line is part of. The collection's key/value pairs will be stored in an array with its name defined as the concatenation of the prefix and parent_key.

For the top level (indent level zero) the data set prefix is used as the parent key so it has no prefix (it's set to ""). All other arrays are prefixed with the root prefix.

Next, the current key is inserted into an (awk-internal) array containing the keys. This array persists throughout the whole awk session and therefore contains keys inserted by prior lines. The key is inserted into the array using its indent as the array index.

keys[indent] = key;

Because this array contains keys from previous lines, any keys with an indent level grater than the current line's indent level are removed:

 for (i in keys) {if (i > indent) {delete keys[i]}}

This leaves the keys array containing the key-chain from the root at indent level 0 to the current line. It removes stale keys that remain when the prior line was indented deeper than the current line.

The final section outputs the bash commands: an input line without a value starts a new indent level (a collection in YAML parlance) and an input line with a value adds a key to the current collection.

The collection's name is the concatenation of the current line's prefix and parent_key.

When a key has a value, a key with that value is assigned to the current collection like this:

printf("%s%s[%s]=\"%s\";\n", prefix, parent_key , key, value);
printf("%s%s[keys]+=\" %s\";\n", prefix, parent_key , key);

The first statement outputs the command to assign the value to an associative array element named after the key and the second one outputs the command to add the key to the collection's space-delimited keys list:

<current_collection>[<key>]="<value>";
<current_collection>[keys]+=" <key>";

When a key doesn't have a value, a new collection is started like this:

printf("%s%s[children]+=\" %s%s\";\n", prefix, parent_key , root_prefix, key);
printf("declare -g -A %s%s;\n", root_prefix, key);

The first statement outputs the command to add the new collection to the current's collection's space-delimited children list and the second one outputs the command to declare a new associative array for the new collection:

<current_collection>[children]+=" <new_collection>"
declare -g -A <new_collection>;

All of the output from yay_parse can be parsed as bash commands by the bash eval or source built-in commands.

Try this

$("#abc").html('<span class = "xyz"> SAMPLE TEXT</span>');

Handle all the css relevant to that span within xyz

This result is the first that pops-up in google, and is more broad than what's happening here. The following will apply to an express server:

I was trying to access resources from a nested folder.

Inside index.html i had

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

The static route was mounted at :

app.use(express.static(__dirname));

But the script.js is located in the nested folder as in: js/myStaticApp/script.js I just changed the static route to:

app.use(express.static(path.join(__dirname, "js")));

Now it works :)

Guava Documentation

The JDK provides Collections.unmodifiableXXX methods, but in our opinion, these can be unwieldy and verbose; unpleasant to use everywhere you want to make defensive copies unsafe: the returned collections are only truly immutable if nobody holds a reference to the original collection inefficient: the data structures still have all the overhead of mutable collections, including concurrent modification checks, extra space in hash tables, etc.

You add web components to a J2EE application in a package called a web application archive (WAR), which is a JAR similar to the package used for Java class libraries. A WAR usually contains other resources besides web components, including:

• Server-side utility classes (database beans, shopping carts, and so on).
• Static web resources (HTML, image, and sound files, and so on)
• Client-side classes (applets and utility classes)

A WAR has a specific hierarchical directory structure. The top-level directory of a WAR is the document root of the application. The document root is where JSP pages, client-side classes and archives, and static web resources are stored.

(source)

So a .war is a .jar, but it contains web application components and is laid out according to a specific structure. A .war is designed to be deployed to a web application server such as Tomcat or Jetty or a Java EE server such as JBoss or Glassfish.

What Tyler Rinker says is correct:

AQ2 <- airquality
AQ2[is.na(AQ2)] <- 0

will do just this.

What you are originally doing is that you are taking from airquality all those rows (cases) that are complete. So, all the cases that do not have any NA's in them, and keep only those.

This particular NuGet package has a habit of losing its references in one of our projects. From time to time I will need to run the following command in the Package Manager Console to restore the references and everything is OK again

This solution will also work for the following URLs, without breaking anchor links to different pages.

http://www.example.com/dir/index.html
http://www.example.com/dir/index.html#anchor

./index.html

etc.

var $root = $('html, body');
$('a').on('click', function(event){
    var hash = this.hash;
    // Is the anchor on the same page?
    if (hash && this.href.slice(0, -hash.length-1) == location.href.slice(0, -location.hash.length-1)) {
        $root.animate({
            scrollTop: $(hash).offset().top
        }, 'normal', function() {
            location.hash = hash;
        });
        return false;
    }
});

I haven't tested this in all browsers, yet.

Why are constructors indeed called "Constructors" ?

The constructor (named __new__) creates and returns a new instance of the class. So the C.__new__ class method is the constructor for the class C.

The C.__init__ instance method is called on a specific instance, after it is created, to initialise it before being passed back to the caller. So that method is the initialiser for new instances of C.

How are they different from methods in a class?

As stated in the official documentation __init__ is called after the instance is created. Other methods do not receive this treatment.

What is their purpose?

The purpose of the constructor C.__new__ is to define custom behaviour during construction of a new C instance.

The purpose of the initialiser C.__init__ is to define custom initialisation of each instance of C after it is created.

For example Python allows you to do:

class Test(object):
    pass

t = Test()

t.x = 10   # here you're building your object t
print t.x

But if you want every instance of Test to have an attribute x equal to 10, you can put that code inside __init__:

class Test(object):
    def __init__(self):
        self.x = 10

t = Test()
print t.x

Every instance method (a method called on a specific instance of a class) receives the instance as its first argument. That argument is conventionally named self.

Class methods, such as the constructor __new__, instead receive the class as their first argument.

Now, if you want custom values for the x attribute all you have to do is pass that value as argument to __init__:

class Test(object):
    def __init__(self, x):
        self.x = x

t = Test(10)
print t.x
z = Test(20)
print t.x

I hope this will help you clear some doubts, and since you've already received good answers to the other questions I will stop here :)

If you are using mac (OSX) :

On you mac:

1. Open Terminal
2. run "ifconfig"
3. Find the line with the ip adress "192.xx.x.x"

If you are testing your website with the address : "localhost:8888/mywebsite" (it depends on your MAMP configurations)

On your phone :

1. Open your browser (e.g Safari)
2. Enter the URL 192.xxx.x.x:8888/mywebsite

Note : you have to be connected on the same network (wifi)

def search(myDict, lookup):

                 a.append(key)
    a=list(set(a))
    return a

if the research involves more keys maybe you should create a list with all the keys

I have a hunch that you have two ruby versions. Please paste the output of following command:

$ which -a ruby

updated regarding to the comment:

Nuke one version and leave only one. I had same problem with two versions looking at different locations for gems. Had me going crazy for few weeks. Put up a bounty here at SO got me same answer I'm giving to you.

All I did was nuke one installation of ruby and left the one managable via ports. I'd suggest doing this:

1. Remove ruby version installed via ports (yum or whatever package manager).
2. Remove ruby version that came with OS (hardcore rm by hand).
3. Install ruby version from ports with different prefix (/usr instead of /usr/local)
4. Reinstall rubygems

You should look into DependencyObjects as used by WPF these follow a similar pattern whereby properties can be assigned at runtime. As mentioned above this ultimately points towards using a hash table.

One other useful thing to have a look at is CSLA.Net. The code is freely available and uses some of the principles\patterns it appears you are after.

Also if you are looking at sorting and filtering I'm guessing you're going to be using some kind of grid. A useful interface to implement is ICustomTypeDescriptor, this lets you effectively override what happens when your object gets reflected on so you can point the reflector to your object's own internal hash table.

purls $.params() used without a parameter will give you a key-value object of the parameters.

jQuerys $.param() will build a querystring from the supplied object/array.

var params = parsedUrl.param();
delete params["page"];

var newUrl = "?page=" + $(this).val() + "&" + $.param(params);

Update
I've no idea why I used delete here...

var params = parsedUrl.param();
params["page"] = $(this).val();

var newUrl = "?" + $.param(params);

Add a width to the .child elements. I personally would use percentages on the margin-left if you want to have it always 4 per row.

DEMO

.child {
    display: inline-block;
    background: blue;
    margin: 10px 0 0 2%;
    flex-grow: 1;
    height: 100px;
    width: calc(100% * (1/4) - 10px - 1px);
}

That's yet another question, which, being wrongly put, spawns A LOT of terrible solutions, all making things awfully complicated to solve a non-existent problem.

The extremely simple and obvious rule for any database interaction is

Always select the only data you need.

From this point of view, the question is wrong and the accepted answer is right. But other proposed solutions are just terrible.

The question is "how to get the count wrong way". One should never answer it straightforward, but instead, the only proper answer is "One should never select the rows to count them. Instead, ALWAYS ask the database to count the rows for you." This rule is so obvious, that it's just improbable to see so many tries to break it.

After learning this rule, we would see that this is an SQL question, not even PDO related. And, were it asked properly, from SQL perspective, the answer would appeared in an instant - DISTINCT.

$num = $db->query('SELECT count(distinct boele) FROM tbl WHERE oele = 2')->fetchColumn();

is the right answer to this particular question.

The opening poster's own solution is also acceptable from the perspective of the aforementioned rule, but would be less efficient in general terms.

To enable use bind() method

$("#id").bind("click",eventhandler);

call this handler

 function  eventhandler(){
      alert("Bind click")
    }

To disable click useunbind()

$("#id").unbind("click");

Scripts are usually loaded in the end of the html page, and MVC recommends the using of bundles, just saying. So my best bet is that your jquery.validate files got altered in some way or are not updated to the latest version, since they do validate e-mail inputs.

So you could either update/refresh your nuget package or write your own function, really.

Here's an example which you would add in an extra file after jquery.validate.unobtrusive:

$.validator.addMethod(
    "email",
    function (value, element) {
        return this.optional( element ) || /^[a-zA-Z0-9.!#$%&'*+\/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/.test( value );
    },
    "This e-mail is not valid"
);

This is just a copy and paste of the current jquery.validate Regex, but this way you could set your custom error message/add extra methods to fields you might want to validate in the near future.

Other answers have noted Jackson and GSON - the popular add-on JSON libraries for Android, and json.org, the bare-bones JSON package that is included in Android.

But I think it is also worth noting that Android now has its own full featured JSON API.

This was added in Honeycomb: API level 11.

This comprises
- android.util.JsonReader: docs, and source
- android.util.JsonWriter: docs, and source

I will also add one additional consideration that pushes me back towards Jackson and GSON: I have found it useful to use 3rd party libraries rather then android.* packages because then the code I write can be shared between client and server. This is particularly relevant for something like JSON, where you might want to serialize data to JSON on one end for sending to the other end. For use cases like that, if you use Java on both ends it helps to avoid introducing android.* dependencies.

Or I guess one could grab the relevant android.* source code and add it to your server project, but I haven't tried that...

The answers here work to open the page in the same browser window/tab.

However, I wanted the page to open in a new window/tab when they click a button. (tab/window decision depends on the user's browser setting)

So here is how it worked to open the page in new tab/window:

<button type="button" onclick="window.open('http://www.example.com/', '_blank');">View Example Page</button>

It doesn't have to be a button, you can use anywhere. Notice the _blank that is used to open in new tab/window.

No plugins or mappings required. Try the built-in "norm" command, which literally executes anything you want on every selected line.

Add # Comments

1. shift V to visually select lines
2. :norm i#

Remove # Comments

1. visually select region as before
2. :norm x

Or if your comments are indented you can do :norm ^x

Notice that these are just ordinary vim commands being preceded by ":norm" to execute them on each line.

More detailed answer for using "norm" command in one of the answers here

jQuery

$('selector').each(function(){ 
  var text = $(this).html();
  text = text.substring(0, text.length-1);

  var text = $(this).html();
  text = text.slice(0,-1);
  $(this).html(text);
})

As mentioned by another poster, Visual Studio generates this as a part of its .gitignore (at least for MVC 4):

# SQL Server files
App_Data/*.mdf
App_Data/*.ldf

Since your project may be a subfolder of your solution, and the .gitignore file is stored in the solution root, this actually won't touch the local database files (Git sees them at projectfolder/App_Data/*.mdf). To account for this, I changed those lines like so:

# SQL Server files
*App_Data/*.mdf
*App_Data/*.ldf

When I add @ComponentScan("com.firstday.spring.boot.services") or scanBasePackages{"com.firstday.spring.boot.services"} jsp is not loaded. So when I add the parent package of project in @SpringBootApplication class it's working fine in my case

Code Example:-

package com.firstday.spring.boot.firstday;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication(scanBasePackages = {"com.firstday.spring.boot"})
public class FirstDayApplication {

    public static void main(String[] args) {
        SpringApplication.run(FirstDayApplication.class, args);
    }

}

mongofiles.exe
mongoimport.exe
mongooplog.exe
mongoperf.exe
mongorestore.exe
mongos.exe
mongos.pdb
mongostat.exe
mongotop.exe

All you need is to add data directory and db directory nested( data/db ) Final view should look like this:

data
bsondump.exe
mongo.exe
mongod.exe

mongoexport.exe
mongofiles.exe
mongoimport.exe
mongooplog.exe
mongoperf.exe

Than simply type in directory where MongoDB sources and data/db dirs exist this command:

C:\my_mongo_dir\bin>mongod --dbpath .\data\db

I used all above changes but still I was getting same issue on my web application.

Quoting Chris: "... when your program quits, any daemon threads are killed automatically.". I think that sums it up. You should be careful when you use them as they abruptly terminate when main program executes to completion.

You can use in this way using bootstrap css. Just remove the active class if already assinged to any row and reassign to the current row.

    $(".table tr").each(function () {
        $(this).attr("class", "");
    });
    $(this).attr("class", "active");

I had a similar issue, but with no source code to run on Xcode.

So if you want to test an application on a real device with a fake location you should use a VPN application.

There are plenty in the App Store to choose from - free ones without the option to choose a specific country/city and free ones which assign you a random location or asks you to choose from a limited set of default options.

This builds on ntc2 and Chris Johnsen's answer. I am using this whenever I want to create a new session with a custom history-limit. I wanted a way to create sessions with limited scrollback without permanently changing my history-limit for future sessions.

tmux set-option -g history-limit 100 \; new-session -s mysessionname \; set-option -g history-limit 2000

This works whether or not there are existing sessions. After setting history-limit for the new session it resets it back to the default which for me is 2000.

I created an executable bash script that makes this a little more useful. The 1st parameter passed to the script sets the history-limit for the new session and the 2nd parameter sets its session name:

#!/bin/bash
tmux set-option -g history-limit "${1}" \; new-session -s "${2}" \; set-option -g history-limit 2000

Actualy the .*? only works in perl. I am not sure what the equivalent grep extended regexp syntax would be. Fortunately you can use perl syntax with grep so grep -P would work but grep -E which is same as egrep would not work (it would be greedy).

If you take a look at the source of the select method, you can see that what it does when you pass a from key is essentially:

find(:select, from, options).find(:option, value, options).select_option

In other words, it finds the <select> you're interested in, then finds the <option> within that, then calls select_option on the <option> node.

You've already pretty much done the first two things, I'd just rearrange them. Then you can tack the select_option method on the end:

find('#organizationSelect').find(:xpath, 'option[2]').select_option

So for me, nobody gave the good answer to the problem that i met which is almost the same than @Kay. For me it's about sorting, sorting table does not occur changes in the mat. I purpose this answer since it's the only topic that i find by searching google. I'm using Angular 6.

As said here:

Since the table optimizes for performance, it will not automatically check for changes to the data array. Instead, when objects are added, removed, or moved on the data array, you can trigger an update to the table's rendered rows by calling its renderRows() method.

So you just have to call renderRows() in your refresh() method to make your changes appears.

See here for integration.

The difference between different date/time formats in ActiveRecord has little to do with Rails and everything to do with whatever database you're using.

Using MySQL as an example (if for no other reason because it's most popular), you have DATE, DATETIME, TIME and TIMESTAMP column data types; just as you have CHAR, VARCHAR, FLOAT and INTEGER.

So, you ask, what's the difference? Well, some of them are self-explanatory. DATE only stores a date, TIME only stores a time of day, while DATETIME stores both.

The difference between DATETIME and TIMESTAMP is a bit more subtle: DATETIME is formatted as YYYY-MM-DD HH:MM:SS. Valid ranges go from the year 1000 to the year 9999 (and everything in between. While TIMESTAMP looks similar when you fetch it from the database, it's really a just a front for a unix timestamp. Its valid range goes from 1970 to 2038. The difference here, aside from the various built-in functions within the database engine, is storage space. Because DATETIME stores every digit in the year, month day, hour, minute and second, it uses up a total of 8 bytes. As TIMESTAMP only stores the number of seconds since 1970-01-01, it uses 4 bytes.

You can read more about the differences between time formats in MySQL here.

In the end, it comes down to what you need your date/time column to do. Do you need to store dates and times before 1970 or after 2038? Use DATETIME. Do you need to worry about database size and you're within that timerange? Use TIMESTAMP. Do you only need to store a date? Use DATE. Do you only need to store a time? Use TIME.

Having said all of this, Rails actually makes some of these decisions for you. Both :timestamp and :datetime will default to DATETIME, while :date and :time corresponds to DATE and TIME, respectively.

This means that within Rails, you only have to decide whether you need to store date, time or both.

Using a union query will remove duplicates, and this is different than the behavior of full outer join that never removes any duplicate:

4                                      5

This is the expected result of full outer join:

------+-------
1     | 1
2     | 2
2     | 2
Null  | 5
4     | Null
4     | Null

This is the result of using left and right Join with union:

value | value
------+-------
Null  | 5 
1     | 1
2     | 2
4     | Null

[SQL Fiddle]

My suggested query is:

select 
    t1.value, t2.value
from t1 
left outer join t2  
  on t1.value = t2.value
union all      -- Using `union all` instead of `union`
select 
    t1.value, t2.value
from t2 
left outer join t1 
  on t1.value = t2.value
where 
    t1.value IS NULL 

Result of above query that is as same as expected result:

value | value
------+-------
1     | 1
2     | 2
2     | 2
4     | NULL
4     | NULL
NULL  | 5

@Steve Chambers: ^{[From comments, with many thanks!]}
Note: This may be the best solution, both for efficiency and for generating the same results as a FULL OUTER JOIN. This blog post also explains it well - to quote from Method 2: "This handles duplicate rows correctly and doesn’t include anything it shouldn’t. It’s necessary to use UNION ALL instead of plain UNION, which would eliminate the duplicates I want to keep. This may be significantly more efficient on large result sets, since there’s no need to sort and remove duplicates."

I decided to add another solution that comes from full outer join visualization and math, it is not better that above but more readable:

Full outer join means (t1 ? t2): all in t1 or in t2
(t1 ? t2) = (t1 n t2) + t1_only + t2_only: all in both t1 and t2 plus all in t1 that aren't in t2 and plus all in t2 that aren't in t1:

-- (t1 n t2): all in both t1 and t2
select t1.value, t2.value
from t1 join t2 on t1.value = t2.value    
union all  -- And plus 
-- all in t1 that not exists in t2
select t1.value, null
from t1
where not exists( select 1 from t2 where t2.value = t1.value)    
union all  -- and plus
-- all in t2 that not exists in t1
select null, t2.value
from t2
where not exists( select 1 from t1 where t2.value = t1.value)

After a bitter almost 24 hours long run trying to make xdebug to work with Netbeans 8.0.2, I have found a solution that, I hope, will work for all Ubuntu and Ubuntu related stacks.

Problem number 1: PHP and xdebug versions must be compatible

Sometimes, if you're running a Linux setup and apt-get to install xdebug, it won't get you the proper xdebug version. In my case, I had the latest php version but an old xdebug version. That must be due to my current Xubuntu version. Software versions are dependent on repositories, which are dependent on the OS version you are running.

Solution: PHP has a neat extension manager called PECL. Follow the instructions given here to have it up and running. First, as pointed out by a member at the comments, you should install PHP's developer package in order to get PECL to work:

sudo apt-get install php5-dev

Then, using PECL, you'll be able to install the latest stable version of xdebug:

sudo pecl install php5-xdebug

Once you do it, the proper version of xdebug will be installed but not ready to use. After that, you'll need to enable it. I've seen many suggestions on how to do it, but the fact of the matter is that PHP needs some modules to be enabled both to the client and the server, in this case Apache. It seems that the best practice here is to use the built in method of enabling modules, called php5enmod. Usage is described here.

Problem number 2: Enable the module correctly

First, you'll need to go inside the /etc/php5 folder. In there, you'll find 3 folders, apache2, cli, and mods_available. The mods_available folder contains text files with instructions to activate a given module. The name convention is [module].ini. Take a look inside a few of them, see how they are set up.

Now you'll have to create your ini file inside mods_available folder. Create a file named xdebug.ini, and inside the file, paste this:

[xdebug]
zend_extension = /usr/lib/php5/20121212/xdebug.so
xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_host=localhost
xdebug.remote_port=9000

Make sure that the directive [xdebug] is present, exactly like the example above. It is imperative for the module to work. In fact, just copy and paste the whole code, you'll be a happier person that way. :D

Note: the zend_extension path is very important. On this example it is pointing o the current version of the PHP engine, but you should first go to /usr/lib/php5 and make sure the folder that is named with numbers is the correct one. Adjust the name to whatever you see there, and while you're at it, check inside the folder to make sure the xdebug.so is really there. It should be, if you did everything right.

Now, with your xdebug.ini created, it's time to enable the module. To do that, open a console and type:

php5enmod xdebug

If everything went right, PHP created two links to this file, one inside /etc/php5/apache2/conf.d and other inside /etc/php5/cli/conf.d

Restart your Apache server and type this on the console:

php -v

You should get something like this:

PHP 5.5.9-1ubuntu4.6 (cli) (built: Feb 13 2015 19:17:11) 
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies
with Zend OPcache v7.0.3, Copyright (c) 1999-2014, by Zend Technologies
with Xdebug v2.3.1, Copyright (c) 2002-2015, by Derick Rethans

Which means the PHP client did read your xdebug.ini file and loaded the xdebug.so module. So far so good.

Now create a phpinfo script somewhere on your web server, and run it. This is what you should see, if everything went wright:

If you see this, Apache also loaded the module, and you are probably ready to go. Now let's see if Netbeans will debug correctly. Create a very simple script, add some variables, give them values, and set a break point on them. Now hit CTRL+F5, click on "step in" on your debugger panel, and see if you get something like this:

Remember to check Netbeans configuration for debugging, under tools/options/php. It should look something like this:

I hope this sheds some light on this rather obscure, confusing problem.

Best wishes!

You can use the following format to generate a tooltip for an image.

<div class="tooltip"><img src="joe.jpg" />
  <span class="tooltiptext">Tooltip text</span>
</div>

Main classes should be under src/main/java
and
test classes should be under src/test/java

If all in the correct places and still main classes are not accessible then
Right click project => Maven => Update Project
Hope so this will resolve the issue

I had this issue recently and I resolved it by simply rolling IE8 back to IE7.

My guess is that IE7 had these files as a wrapper for working on Windows XP, but IE8 was likely made to work with Vista/7 so it removed the files because the later editions just don't use the shim.

A constructor is a special kind of method that allows you to create a new instance of a class. It concerns itself with initialization logic.

if c:\folder1\folder2\folder3\bin is the path then the following code will return the path base folder of bin folder

//string directory=System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString());

string directory=System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString();

ie,c:\folder1\folder2\folder3

if you want folder2 path then you can get the directory by

string directory = System.IO.Directory.GetParent(System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString()).ToString();

then you will get path as c:\folder1\folder2\

Inline javascript

In a working draft of the CSS2 spec it was declared that you could use pseudo-classes inline like this:

<a href="http://www.w3.org/Style/CSS"
   style="{color: blue; background: white}  /* a+=0 b+=0 c+=0 */
      :visited {color: green}           /* a+=0 b+=1 c+=0 */
      :hover {background: yellow}       /* a+=0 b+=1 c+=0 */
      :visited:hover {color: purple}    /* a+=0 b+=2 c+=0 */
     ">
</a>

but it was never implemented in the release of the spec as far as I know.

A simple definition: A web service is a function that can be accessed by other programs over the web (HTTP).

For example, when you create a website in PHP that outputs HTML, its target is the browser and by extension the human reading the page in the browser. A web service is not targeted at humans but rather at other programs.

So your PHP site that generates a random integer could be a web service if it outputs the integer in a format that may be consumed by another program. It might be in an XML format or another format, as long as other programs can understand the output.

The full definition is obviously more complex but you asked for plain English.

Since all the players are numbered I would just use an ArrayList<Player>()

Something like

List<Player> players = new ArrayList<Player>();

System.out.printf("Give the number of the players ");
int number_of_players = scanner.nextInt();
scanner.nextLine(); // discard the rest of the line.

for(int k = 0;k < number_of_players; k++){
     System.out.printf("Give the name of player %d: ", k + 1);
     String name_of_player = scanner.nextLine();
     players.add(new Player(name_of_player,0)); //k=id and 0=score
}

for(Player player: players) {  
    System.out.println("Name of player in this round:" + player.getName());

Important question. The server I use (Ubuntu 12.04) had easy_install3 but not pip3. This is how I installed Pip and then other packages to my home folder

1. Asked admin to install Ubuntu package python3-setuptools

2. Installed pip

Like this:

 easy_install3 --prefix=$HOME/.local pip
 mkdir -p $HOME/.local/lib/python3.2/site-packages
 easy_install3 --prefix=$HOME/.local pip

1. Add Pip (and other Python apps to path)

Like this:

PATH="$HOME/.local/bin:$PATH"
echo PATH="$HOME/.local/bin:$PATH" > $HOME/.profile

1. Install Python package

like this

pip3 install --user httpie

# test httpie package
http httpbin.org

If you are only concerned with getting an integer value out of a whole floating point number (i.e. 12347.9999 or 54321.0001), this approach (borrowed and modified from above) will do the trick:

my $rounded = floor($float + 0.1); 

AppDomain.CurrentDomain.BaseDirectory

works with MbUnit GUI.

<div id="demo"></div>

<script type="text/javascript">
    if(document.getElementById('number1').checked) {
        var demo = document.getElementById("demo");    
        demo.innerHtml='<h1>Hello member</h1>';
    } else {
        demo.innerHtml='';
    }
</script>

Always coming back to this page when a designer stretches a font on me. The accepted solution works great, but I frequently run into issues with margins.

Would recommend using the transform on the height instead of the width if you're running into issues, was a life safer for me in my current project.

.font-stretch {
    display: inline-block;
    -webkit-transform: scale(1,.9);
    -moz-transform: scale(1,.9);
    -ms-transform: scale(1,.9);
    -o-transform: scale(1,.9);
    transform: scale(1,.9);
}

If nothing else works, make sure that you have correct permissions and ownership set up during building. A quick fix can be:

sudo chown -R <you>:<your_group> *
sudo chmod -R 755 *

Yes. Hit Ctrl-R then ". If you have literal control characters in what you have yanked, use Ctrl-R, Ctrl-O, ".

Here is an explanation of what you can do with registers. What you can do with registers is extraordinary, and once you know how to use them you cannot live without them.

Registers are basically storage locations for strings. Vim has many registers that work in different ways:

• 0 (yank register: when you use y in normal mode, without specifying a register, yanked text goes there and also to the default register),
• 1 to 9 (shifting delete registers, when you use commands such as c or d, what has been deleted goes to register 1, what was in register 1 goes to register 2, etc.),
• " (default register, also known as unnamed register. This is where the " comes in Ctrl-R, "),
• a to z for your own use (capitalized A to Z are for appending to corresponding registers).
• _ (acts like /dev/null (Unix) or NUL (Windows), you can write to it but it's discarded and when you read from it, it is always empty),
• - (small delete register),
• / (search pattern register, updated when you look for text with /, ?, * or # for instance; you can also write to it to dynamically change the search pattern),
• : (stores last VimL typed command via Q or :, readonly),
• + and * (system clipboard registers, you can write to them to set the clipboard and read the clipboard contents from them)

See :help registers for the full reference.

You can, at any moment, use :registers to display the contents of all registers. Synonyms and shorthands for this command are :display, :reg and :di.

In Insert or Command-line mode, Ctrl-R plus a register name, inserts the contents of this register. If you want to insert them literally (no auto-indenting, no conversion of control characters like 0x08 to backspace, etc), you can use Ctrl-R, Ctrl-O, register name. See :help i_CTRL-R and following paragraphs for more reference.

But you can also do the following (and I probably forgot many uses for registers).

• In normal mode, hit ":p. The last command you used in vim is pasted into your buffer.
  Let's decompose: " is a Normal mode command that lets you select what register is to be used during the next yank, delete or paste operation. So ": selects the colon register (storing last command). Then p is a command you already know, it pastes the contents of the register.

  cf. :help ", :help quote_:

• You're editing a VimL file (for instance your .vimrc) and would like to execute a couple of consecutive lines right now: yj:@"Enter.
  Here, yj yanks current and next line (this is because j is a linewise motion but this is out of scope of this answer) into the default register (also known as the unnamed register). Then the :@ Ex command plays Ex commands stored in the register given as argument, and " is how you refer to the unnamed register. Also see the top of this answer, which is related.

  Do not confuse " used here (which is a register name) with the " from the previous example, which was a Normal-mode command.

  cf. :help :@ and :help quote_quote

• Insert the last search pattern into your file in Insert mode, or into the command line, with Ctrl-R, /.

  cf. :help quote_/, help i_CTRL-R

  Corollary: Keep your search pattern but add an alternative: / Ctrl-R, / \|alternative.

• You've selected two words in the middle of a line in visual mode, yanked them with y, they are in the unnamed register. Now you want to open a new line just below where you are, with those two words: :pu. This is shorthand for :put ". The :put command, like many Ex commands, works only linewise.

  cf. :help :put

  You could also have done: :call setreg('"', @", 'V') then p. The setreg function sets the register of which the name is given as first argument (as a string), initializes it with the contents of the second argument (and you can use registers as variables with the name @x where x is the register name in VimL), and turns it into the mode specified in the third argument, V for linewise, nothing for characterwise and literal ^V for blockwise.

  cf. :help setreg(). The reverse functions are getreg() and getregtype().

• If you have recorded a macro with qa...q, then :echo @a will tell you what you have typed, and @a will replay the macro (probably you knew that one, very useful in order to avoid repetitive tasks)

  cf. :help q, help @

  Corollary from the previous example: If you have 8go in the clipboard, then @+ will play the clipboard contents as a macro, and thus go to the 8th byte of your file. Actually this will work with almost every register. If your last inserted string was dd in Insert mode, then @. will (because the . register contains the last inserted string) delete a line. (Vim documentation is wrong in this regard, since it states that the registers #, %, : and . will only work with p, P, :put and Ctrl-R).

  cf. :help @

  Don't confuse :@ (command that plays Vim commands from a register) and @ (normal-mode command that plays normal-mode commands from a register).

  Notable exception is @:. The command register does not contain the initial colon neither does it contain the final carriage return. However in Normal mode, @: will do what you expect, interpreting the register as an Ex command, not trying to play it in Normal mode. So if your last command was :e, the register contains e but @: will reload the file, not go to end of word.

  cf. :help @:

• Show what you will be doing in Normal mode before running it: @='dd' Enter. As soon as you hit the = key, Vim switches to expression evaluation: as you enter an expression and hit Enter, Vim computes it, and the result acts as a register content. Of course the register = is read-only, and one-shot. Each time you start using it, you will have to enter a new expression.

  cf. :help quote_=

  Corollary: If you are editing a command, and you realize that you should need to insert into your command line some line from your current buffer: don't press Esc! Use Ctrl-R =getline(58) Enter. After that you will be back to command line editing, but it has inserted the contents of the 58th line.

• Define a search pattern manually: :let @/ = 'foo'

  cf. :help :let

  Note that doing that, you needn't to escape / in the pattern. However you need to double all single quotes of course.

• Copy all lines beginning with foo, and afterwards all lines containing bar to clipboard, chain these commands: qaq (resets the a register storing an empty macro inside it), :g/^foo/y A, :g/bar/y A, :let @+ = @a.

  Using a capital register name makes the register work in append mode

  Better, if Q has not been remapped by mswin.vim, start Ex mode with Q, chain those “colon commands” which are actually better called “Ex commands”, and go back to Normal mode by typing visual.

  cf. :help :g, :help :y, :help Q

• Double-space your file: :g/^/put _. This puts the contents of the black hole register (empty when reading, but writable, behaving like /dev/null) linewise, after each line (because every line has a beginning!).

• Add a line containing foo before each line: :g/^/-put ='foo'. This is a clever use of the expression register. Here, - is a synonym for .-1 (cf. :help :range). Since :put puts the text after the line, you have to explicitly tell it to act on the previous one.

• Copy the entire buffer to the system clipboard: :%y+.

  cf. :help :range (for the % part) and :help :y.

• If you have misrecorded a macro, you can type :let @a=' Ctrl-R =replace(@a,"'","''",'g') Enter ' and edit it. This will modify the contents of the macro stored in register a, and it's shown here how you can use the expression register to do that.

• If you did dddd, you might do uu in order to undo. With p you could get the last deleted line. But actually you can also recover up to 9 deletes with the registers @1 through @9.

  Even better, if you do "1P, then . in Normal mode will play "2P, and so on.

  cf. :help . and :help quote_number

• If you want to insert the current date in Insert mode: Ctrl-R=strftime('%y%m%d')Enter.

  cf. :help strftime()

Once again, what can be confusing:

• :@ is a command-line command that interprets the contents of a register as vimscript and sources it

• @ in normal mode command that interprets the contents of a register as normal-mode keystrokes (except when you use : register, that contains last played command without the initial colon: in this case it replays the command as if you also re-typed the colon and the final return key).

• " in normal mode command that helps you select a register for yank, paste, delete, correct, etc.

• " is also a valid register name (the default, or unnamed, register) and therefore can be passed as an arguments for commands that expect register names

Here is your code. I'm assuming you're using python 3 based on the your use of print() and input():

import random

def main():
    #random.seed() --> don't need random.seed()

    #Prompts the user to enter the number of tickets they wish to play.

    #python 3 version:
    tickets = int(input("How many lottery tickets do you want?\n"))

    #Creates the dictionaries "winning_numbers" and "guess." Also creates the variable "winnings" for total amount of money won.
    winning_numbers = []
    winnings = 0

    #Generates the winning lotto numbers.
    for i in range(tickets * 5):
        #del winning_numbers[:] what is this line for?
        randNum = random.randint(1,30)
        while randNum in winning_numbers:    
            randNum = random.randint(1,30)
        winning_numbers.append(randNum)

    print(winning_numbers)
    guess = getguess(tickets)
    nummatches = checkmatch(winning_numbers, guess)

    print("Ticket #"+str(i+1)+": The winning combination was",winning_numbers,".You matched",nummatches,"number(s).\n")

    winningRanks = [0, 0, 10, 500, 20000, 1000000]

    winnings = sum(winningRanks[:nummatches + 1])

    print("You won a total of",winnings,"with",tickets,"tickets.\n")


#Gets the guess from the user.
def getguess(tickets):
    guess = []
    for i in range(tickets):
        bubble = [int(i) for i in input("What numbers do you want to choose for ticket #"+str(i+1)+"?\n").split()]
        guess.extend(bubble)
        print(bubble)
    return guess

#Checks the user's guesses with the winning numbers.
def checkmatch(winning_numbers, guess):
    match = 0
    for i in range(5):
        if guess[i] == winning_numbers[i]:
            match += 1
    return match

main()

Indeed, Python does garbage collection through reference counting. As soon as the last reference to an object falls out of scope, it is deleted. In your example:

a = A()
a.kill()

I don't believe there's any way for variable 'a' to implicitly set itself to None.

Yes VBA is the way to go.

But, if you don't need to have a cell with formula that auto-counts/updates the number of cells with a particular colour, an alternative is simply to use the 'Find and Replace' function and format the cell to have the appropriate colour fill.

Hitting 'Find All' will give you the total number of cells found at the bottom left of the dialogue box.

This becomes especially useful if your search range is massive. The VBA script will be very slow but the 'Find and Replace' function will still be very quick.

To start the standalone Device Monitor application, enter the following on the command line in the android-sdk/tools/ directory:

monitor

You can then link the tool to a connected device by selecting the device from the Devices pane. If you have trouble viewing panes or windows, select Window > Reset Perspective from the menu bar.

• Note: Each device can be attached to only one debugger process at a time. So, for example, if you are using Android Studio to debug your app on a device, you need to disconnect the Android Studio debugger from the device before you attach a debugger process from the Android Device Monitor.

reference : https://developer.android.com/studio/profile/monitor.html

=> You Can change minSdkVersion 16 And open Device File Explorer

• Device File Explorer work same as a Android Device Monitor

HTTP COOKIES

Cookies are key/value pairs used by websites to store state information on the browser. Say you have a website (example.com), when the browser requests a webpage the website can send cookies to store information on the browser.

Browser request example:

GET /index.html HTTP/1.1
Host: www.example.com

Example answer from the server:

HTTP/1.1 200 OK
Content-type: text/html
Set-Cookie: foo=10
Set-Cookie: bar=20; Expires=Fri, 30 Sep 2011 11:48:00 GMT
... rest  of the response

Here two cookies foo=10 and bar=20 are stored on the browser. The second one will expire on 30 September. In each subsequent request the browser will send the cookies back to the server.

GET /spec.html HTTP/1.1
Host: www.example.com
Cookie: foo=10; bar=20
Accept: */*

SESSIONS: Server side cookies

Server side cookies are known as "sessions". The website in this case stores a single cookie on the browser containing a unique Session Identifier. Status information (foo=10 and bar=20 above) are stored on the server and the Session Identifier is used to match the request with the data stored on the server.

Examples of usage

You can use both sessions and cookies to store: authentication data, user preferences, the content of a chart in an e-commerce website, etc...

Pros and Cons

Below pros and cons of the solutions. These are the first that comes to my mind, there are surely others.

Cookie Pros:

• scalability: all the data is stored in the browser so each request can go through a load balancer to different webservers and you have all the information needed to fullfill the request;
• they can be accessed via javascript on the browser;
• not being on the server they will survive server restarts;
• RESTful: requests don't depend on server state

Cookie Cons:

• storage is limited to 80 KB (20 cookies, 4 KB each)
• secure cookies are not easy to implement: take a look at the paper A secure cookie protocol

Session Pros:

• generally easier to use, in PHP there's probably not much difference.
• unlimited storage

Session Cons:

• more difficult to scale
• on web server restarts you can lose all sessions or not depending on the implementation
• not RESTful

It seams that missing dependency of python-dev, install python-dev and then try to install seaborn, if you are using Ubuntu:

sudo apt-get install python-dev -y
pip install seaborn

['a','b','c'].flatMap(function(e) {
    return [e, e+ 'x', e+ 'y',  e+ 'z'  ];
});
//['a', 'ax', 'ay', 'az', 'b', 'bx', 'by', 'bz', 'c', 'cx', 'cy', 'cz']


['a','b','c'].map(function(e) {
    return [e, e+ 'x', e+ 'y',  e+ 'z'  ];
});
//[Array[4], Array[4], Array[4]]

You use flatMap when you have an Observable whose results are more Observables.

If you have an observable which is produced by an another observable you can not filter, reduce, or map it directly because you have an Observable not the data. If you produce an observable choose flatMap over map; then you are okay.

As in second snippet, if you are doing async operation you need to use flatMap.

var source = Rx.Observable.interval(100).take(10).map(function(num){_x000D_
    return num+1_x000D_
});_x000D_
source.subscribe(function(e){_x000D_
    console.log(e)_x000D_
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/rxjs/5.4.1/Rx.min.js"></script>

var source = Rx.Observable.interval(100).take(10).flatMap(function(num){_x000D_
    return Rx.Observable.timer(100).map(() => num)_x000D_
});_x000D_
source.subscribe(function(e){_x000D_
    console.log(e)_x000D_
})

This is because images and tmp_file_upload are only writable by root user. For upload to work we need to make the owner of those folders same as httpd process owner OR make them globally writable (bad practice).

1. Check apache process owner: $ps aux | grep httpd. The first column will be the owner typically it will be nobody

2. Change the owner of images and tmp_file_upload to be become nobody or whatever the owner you found in step 1.

   $sudo chown nobody /var/www/html/mysite/images/
   
   $sudo chown nobody /var/www/html/mysite/tmp_file_upload/
   

3. Chmod images and tmp_file_upload now to be writable by the owner, if needed [Seems you already have this in place]. Mentioned in @Dmitry Teplyakov answer.

   $ sudo chmod -R 0755 /var/www/html/mysite/images/
   
   $ sudo chmod -R 0755 /var/www/html/mysite/tmp_file_upload/
   

4. For more details why this behavior happend, check the manual http://php.net/manual/en/ini.core.php#ini.upload-tmp-dir , note that it also talking about open_basedir directive.

Fiddle : Demo

The best solution I could find at present time to open a window maximized is (Internet Explorer 11, Chrome 49, Firefox 45):

  var popup = window.open("your_url", "popup", "fullscreen");
  if (popup.outerWidth < screen.availWidth || popup.outerHeight < screen.availHeight)
  {
    popup.moveTo(0,0);
    popup.resizeTo(screen.availWidth, screen.availHeight);
  }

see https://jsfiddle.net/8xwocrp6/7/

Note 1: It does not work on Edge (13.1058686). Not sure whether it's a bug or if it's as designed (I've filled a bug report, we'll see what they have to say about it). Here is a workaround:

if (navigator.userAgent.match(/Edge\/\d+/g))
{
    return window.open("your_url", "popup", "width=" + screen.width + ",height=" + screen.height);
}

Note 2: moveTo or resizeTo will not work (Access denied) if the window you are opening is on another domain.

It is in a folder with your application's name in Application Data folder in User's home folder (C:\documents and settings\user on xp and c:\users\user on Windows Vista).

There is some information here also.

PS:- try accessing it by %appdata% in run box!

You are not writing your code inside any function, you can return from functions only. Remove return statement and just print the value you want.

Sharing my solution, because I was not completely satisfied with the rest. My problem with AfterViewChecked is that sometimes I'm scrolling up, and for some reason, this life hook gets called and it scrolls me down even if there were no new messages. I tried using OnChanges but this was an issue, which lead me to this solution. Unfortunately, using only DoCheck, it was scrolling down before the messages were rendered, which was not useful either, so I combined them so that DoCheck is basically indicating AfterViewChecked if it should call scrollToBottom.

Happy to receive feedback.

export class ChatComponent implements DoCheck, AfterViewChecked {

    @Input() public messages: Message[] = [];
    @ViewChild('scrollable') private scrollable: ElementRef;

    private shouldScrollDown: boolean;
    private iterableDiffer;

    constructor(private iterableDiffers: IterableDiffers) {
        this.iterableDiffer = this.iterableDiffers.find([]).create(null);
    }

    ngDoCheck(): void {
        if (this.iterableDiffer.diff(this.messages)) {
            this.numberOfMessagesChanged = true;
        }
    }

    ngAfterViewChecked(): void {
        const isScrolledDown = Math.abs(this.scrollable.nativeElement.scrollHeight - this.scrollable.nativeElement.scrollTop - this.scrollable.nativeElement.clientHeight) <= 3.0;

        if (this.numberOfMessagesChanged && !isScrolledDown) {
            this.scrollToBottom();
            this.numberOfMessagesChanged = false;
        }
    }

    scrollToBottom() {
        try {
            this.scrollable.nativeElement.scrollTop = this.scrollable.nativeElement.scrollHeight;
        } catch (e) {
            console.error(e);
        }
    }

If you want to make a change global to the whole notebook:

import matplotlib.pyplot as plt
%matplotlib inline
plt.rcParams["figure.figsize"] = [10, 5]

I came here looking for a possible explanation before taking a closer look at the lines preceding the linker error. It turned out to have been an additional executable for which the global declaration was missing!

Try using the d as pointer y.append(*d)

Well, there are different implementations for different browsers.

In my mind, the simplest and most elegant solution is using CSS calc(). Unfortunately, this method is unavailable in ie8 and less, and also not available in android browsers and mobile opera. If you're using separate methods for that, however, you can try this: http://jsfiddle.net/uRskD/

The markup:

<div id="header"></div>
<div id="body"></div>
<div id="footer"></div>

And the CSS:

html, body {
    height: 100%;
    margin: 0;
}
#header {
    background: #f0f;
    height: 20px;
}
#footer {
    background: #f0f;
    height: 20px;
}
#body {
    background: #0f0;
    min-height: calc(100% - 40px);
}

My secondary solution involves the sticky footer method and box-sizing. This basically allows for the body element to fill 100% height of its parent, and includes the padding in that 100% with box-sizing: border-box;. http://jsfiddle.net/uRskD/1/

html, body {
    height: 100%;
    margin: 0;
}
#header {
    background: #f0f;
    height: 20px;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
}
#footer {
    background: #f0f;
    height: 20px;
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
}
#body {
    background: #0f0;
    min-height: 100%;
    box-sizing: border-box;
    padding-top: 20px;
    padding-bottom: 20px;
}

My third method would be to use jQuery to set the min-height of the main content area. http://jsfiddle.net/uRskD/2/

html, body {
    height: 100%;
    margin: 0;
}
#header {
    background: #f0f;
    height: 20px;
}
#footer {
    background: #f0f;
    height: 20px;
}
#body {
    background: #0f0;
}

And the JS:

$(function() {
    headerHeight = $('#header').height();
    footerHeight = $('#footer').height();
    windowHeight = $(window).height();
   $('#body').css('min-height', windowHeight - headerHeight - footerHeight);
});

You need to change the default layout type of top level QWidget object from Break layout type to other layout types (Vertical Layout, Horizontal Layout, Grid Layout, Form Layout). For example:

To something like this:

If you have multiple active buttons on one page then you can do something like this:

Mark the first button you want to trigger on the Enter keypress as the default button on the form. For the second button, associate it to the Backspace button on the keyboard. The Backspace eventcode is 8.

$(document).on("keydown", function(event) {_x000D_
  if (event.which.toString() == "8") {_x000D_
    var findActiveElementsClosestForm = $(document.activeElement).closest("form");_x000D_
_x000D_
    if (findActiveElementsClosestForm && findActiveElementsClosestForm.length) {_x000D_
      $("form#" + findActiveElementsClosestForm[0].id + " .secondary_button").trigger("click");_x000D_
    }_x000D_
  }_x000D_
});

<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js"></script>_x000D_
_x000D_
<form action="action" method="get" defaultbutton="TriggerOnEnter">_x000D_
  <input type="submit" id="PreviousButton" name="prev" value="Prev" class="secondary_button" />_x000D_
  <input type="submit" id='TriggerOnEnter' name="next" value="Next" class="primary_button" />_x000D_
</form>

Best that works for me:

 .left{
   width:140px;
   float:left;
   height:100%;
 }

 .right{
   margin-left:140px;
 }

ulimit max memory size and virtual memory set to unlimited?

I hesitate to post this answer, it is actually technically possible but it doesn't work that well in practice. The version numbers of the CLR and the core framework assemblies were not changed in 4.5. You still target v4.0.30319 of the CLR and the framework assembly version numbers are still 4.0.0.0. The only thing that's distinctive about the assembly manifest when you look at it with a disassembler like ildasm.exe is the presence of a [TargetFramework] attribute that says that 4.5 is needed, that would have to be altered. Not actually that easy, it is emitted by the compiler.

The biggest difference is not that visible, Microsoft made a long-overdue change in the executable header of the assemblies. Which specifies what version of Windows the executable is compatible with. XP belongs to a previous generation of Windows, started with Windows 2000. Their major version number is 5. Vista was the start of the current generation, major version number 6.

.NET compilers have always specified the minimum version number to be 4.00, the version of Windows NT and Windows 9x. You can see this by running dumpbin.exe /headers on the assembly. Sample output looks like this:

OPTIONAL HEADER VALUES
             10B magic # (PE32)
            ...
            4.00 operating system version
            0.00 image version
            4.00 subsystem version              // <=== here!!
               0 Win32 version
            ...

What's new in .NET 4.5 is that the compilers change that subsystem version to 6.00. A change that was over-due in large part because Windows pays attention to that number, beyond just checking if it is small enough. It also turns on appcompat features since it assumes that the program was written to work on old versions of Windows. These features cause trouble, particularly the way Windows lies about the size of a window in Aero is troublesome. It stops lying about the fat borders of an Aero window when it can see that the program was designed to run on a Windows version that has Aero.

You can alter that version number and set it back to 4.00 by running Editbin.exe on your assemblies with the /subsystem option. This answer shows a sample postbuild event.

That's however about where the good news ends, a significant problem is that .NET 4.5 isn't very compatible with .NET 4.0. By far the biggest hang-up is that classes were moved from one assembly to another. Most notably, that happened for the [Extension] attribute. Previously in System.Core.dll, it got moved to Mscorlib.dll in .NET 4.5. That's a kaboom on XP if you declare your own extension methods, your program says to look in Mscorlib for the attribute, enabled by a [TypeForwardedTo] attribute in the .NET 4.5 version of the System.Core reference assembly. But it isn't there when you run your program on .NET 4.0

And of course there's nothing that helps you stop using classes and methods that are only available on .NET 4.5. When you do, your program will fail with a TypeLoadException or MissingMethodException when run on 4.0

Just target 4.0 and all of these problems disappear. Or break that logjam and stop supporting XP, a business decision that programmers cannot often make but can certainly encourage by pointing out the hassles that it is causing. There is of course a non-zero cost to having to support ancient operating systems, just the testing effort is substantial. A cost that isn't often recognized by management, Windows compatibility is legendary, unless it is pointed out to them. Forward that cost to the client and they tend to make the right decision a lot quicker :) But we can't help you with that.

What browser are you testing in?

What DOCType have you set?

How exactly are you declaring your CSS?

Are you sure you haven't missed a ; before/after the overflow-y: scroll?

I've just tested the following in IE7 and Firefox and it works fine

<!-- Scroll bar present but disabled when less content -->_x000D_
<div style="width: 200px; height: 100px; overflow-y: scroll;">_x000D_
  test_x000D_
</div>_x000D_
_x000D_
<!-- Scroll bar present and enabled when more contents -->        _x000D_
<div style="width: 200px; height: 100px; overflow-y: scroll;">_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
</div>

Here's an alternative way, that does not involve any "hacks", but requires ASP.NET 4.0 or later:

//Global.asax
private void Application_Error(object sender, EventArgs e)
{
    var ex = Server.GetLastError();
    var httpException = ex as HttpException ?? ex.InnerException as HttpException;
    if(httpException == null) return;

    if(httpException.WebEventCode == WebEventCodes.RuntimeErrorPostTooLarge)
    {
        //handle the error
        Response.Write("Sorry, file is too big"); //show this message for instance
    }
}

This is because you have wrong selector. According to your markup, .ui-icon and .ui-icon-circle-triangle-w" should point to the same <span> element. So you should use:

$(".ui-icon.ui-icon-circle-triangle-w").html("<<");

or

$(".ui-datepicker-prev .ui-icon").html("<<");

or

$(".ui-datepicker-prev span").html("<<");

Just in case this helps someone, I was getting this error because I completely missed the stated fact that the scope prefix must not be used when calling a local scope. So if you defined a local scope in your model like this:

public function scopeRecentFirst($query)
{
    return $query->orderBy('updated_at', 'desc');
}

You should call it like:

$CurrentUsers = \App\Models\Users::recentFirst()->get();

Note that the prefix scope is not present in the call.

Simple example...

Let's say the child view controller has a UISlider and we want to pass the value of the slider back to the parent via a delegate.

In the child view controller's header file, declare the delegate type and its methods:

ChildViewController.h

#import <UIKit/UIKit.h>

// 1. Forward declaration of ChildViewControllerDelegate - this just declares
// that a ChildViewControllerDelegate type exists so that we can use it
// later.
@protocol ChildViewControllerDelegate;

// 2. Declaration of the view controller class, as usual
@interface ChildViewController : UIViewController

// Delegate properties should always be weak references
// See http://stackoverflow.com/a/4796131/263871 for the rationale
// (Tip: If you're not using ARC, use `assign` instead of `weak`)
@property (nonatomic, weak) id<ChildViewControllerDelegate> delegate;

// A simple IBAction method that I'll associate with a close button in
// the UI. We'll call the delegate's childViewController:didChooseValue: 
// method inside this handler.
- (IBAction)handleCloseButton:(id)sender;

@end

// 3. Definition of the delegate's interface
@protocol ChildViewControllerDelegate <NSObject>

- (void)childViewController:(ChildViewController*)viewController 
             didChooseValue:(CGFloat)value;

@end

In the child view controller's implementation, call the delegate methods as required.

ChildViewController.m

#import "ChildViewController.h"

@implementation ChildViewController

- (void)handleCloseButton:(id)sender {
    // Xcode will complain if we access a weak property more than 
    // once here, since it could in theory be nilled between accesses
    // leading to unpredictable results. So we'll start by taking
    // a local, strong reference to the delegate.
    id<ChildViewControllerDelegate> strongDelegate = self.delegate;

    // Our delegate method is optional, so we should 
    // check that the delegate implements it
    if ([strongDelegate respondsToSelector:@selector(childViewController:didChooseValue:)]) {
        [strongDelegate childViewController:self didChooseValue:self.slider.value];
    }
}

@end

In the parent view controller's header file, declare that it implements the ChildViewControllerDelegate protocol.

RootViewController.h

#import <UIKit/UIKit.h>
#import "ChildViewController.h"

@interface RootViewController : UITableViewController <ChildViewControllerDelegate>

@end

In the parent view controller's implementation, implement the delegate methods appropriately.

RootViewController.m

#import "RootViewController.h"

@implementation RootViewController

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    ChildViewController *detailViewController = [[ChildViewController alloc] init];
    // Assign self as the delegate for the child view controller
    detailViewController.delegate = self;
    [self.navigationController pushViewController:detailViewController animated:YES];
}

// Implement the delegate methods for ChildViewControllerDelegate
- (void)childViewController:(ChildViewController *)viewController didChooseValue:(CGFloat)value {

    // Do something with value...

    // ...then dismiss the child view controller
    [self.navigationController popViewControllerAnimated:YES];
}

@end

Hope this helps!

I am also a Windows user. And I have installed Python 3.7 and when I try to install any package it throws the same error that you are getting.

Try this out. This worked for me.

python -m pip install numpy

And whenever you install new package just write python -m pip install <package_name>

Hope this is helpful.

java 8 base solution:

List duplicates =    
list.stream().collect(Collectors.groupingBy(Function.identity()))
    .entrySet()
    .stream()
    .filter(e -> e.getValue().size() > 1)
    .map(Map.Entry::getKey)
    .collect(Collectors.toList());

Set item using data['id'] = ....

import json

with open('data.json', 'r+') as f:
    data = json.load(f)
    data['id'] = 134 # <--- add `id` value.
    f.seek(0)        # <--- should reset file position to the beginning.
    json.dump(data, f, indent=4)
    f.truncate()     # remove remaining part

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)'});
});

I am not sure about the browser compatibility

word-break: break-all;

Also you can use the <wbr> tag

<wbr> (word break) means: "The browser may insert a line break here, if it wishes." It the browser does not think a line break necessary nothing happens.

You may simply use this query

alter table abc auto_increment = 1;

Sub button2_click()
'
' Button2_Click Macro
'
' Keyboard Shortcut: Ctrl+Shift+Q
'

It's not an official term. I guess it means knowledge of the Java language itself and the most important parts of the standard API (java.lang, java.io, java.utils packages, basically), as opposed to the multitude of specialzed APIs and frameworks (J2EE, JPA, JNDI, JSTL, ...) that are often required for Java jobs.

Here is a query which you can use to search for anything in from your database as a search result ,

SELECT * FROM tbl_customer 
    WHERE CustomerName LIKE '%".$search."%'
    OR Address LIKE '%".$search."%' 
    OR City LIKE '%".$search."%' 
    OR PostalCode LIKE '%".$search."%' 
    OR Country LIKE '%".$search."%'

Using this code will help you search in for multiple columns easily

Spring has some standard events which you can handle.

To do that, you must create and register a bean that implements the ApplicationListener interface, something like this:

package test.pack.age;

import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;

public class ApplicationListenerBean implements ApplicationListener {

    @Override
    public void onApplicationEvent(ApplicationEvent event) {
        if (event instanceof ContextRefreshedEvent) {
            ApplicationContext applicationContext = ((ContextRefreshedEvent) event).getApplicationContext();
            // now you can do applicationContext.getBean(...)
            // ...
        }
    }
}

You then register this bean within your servlet.xml or applicationContext.xml file:

<bean id="eventListenerBean" class="test.pack.age.ApplicationListenerBean" />

and Spring will notify it when the application context is initialized.

In Spring 3 (if you are using this version), the ApplicationListener class is generic and you can declare the event type that you are interested in, and the event will be filtered accordingly. You can simplify a bit your bean code like this:

public class ApplicationListenerBean implements ApplicationListener<ContextRefreshedEvent> {

    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        ApplicationContext applicationContext = event.getApplicationContext();
        // now you can do applicationContext.getBean(...)
        // ...
    }
}

This is actually a pretty common problem for newcomers to Python—especially since, across the standard library and popular third-party libraries, some reading functions strip out newlines, but almost no writing functions (except the log-related stuff) add them.

So, there's a lot of Python code out there that does things like:

fw.write('\n'.join(line_list) + '\n')

or

fw.write(line + '\n' for line in line_list)

Either one is correct, and of course you could even write your own writelinesWithNewlines function that wraps it up…

But you should only do this if you can't avoid it.

It's better if you can create/keep the newlines in the first place—as in Greg Hewgill's suggestions:

line_list.append(new_line + "\n")

And it's even better if you can work at a higher level than raw lines of text, e.g., by using the csv module in the standard library, as esuaro suggests.

For example, right after defining fw, you might do this:

cw = csv.writer(fw, delimiter='|')

Then, instead of this:

new_line = d[looking_for]+'|'+'|'.join(columns[1:])
line_list.append(new_line)

You do this:

row_list.append(d[looking_for] + columns[1:])

And at the end, instead of this:

fw.writelines(line_list)

You do this:

cw.writerows(row_list)

Finally, your design is "open a file, then build up a list of lines to add to the file, then write them all at once". If you're going to open the file up top, why not just write the lines one by one? Whether you're using simple writes or a csv.writer, it'll make your life simpler, and your code easier to read. (Sometimes there can be simplicity, efficiency, or correctness reasons to write a file all at once—but once you've moved the open all the way to the opposite end of the program from the write, you've pretty much lost any benefits of all-at-once.)

I see a few answers here, most of them complicated or with some cons (additional divs, text-align doesn't work because of display: inline-block). I think this is the simplest and problem-free solution:

HTML:

<table>
    <!-- Rows -->
    <tr>
        <td>E-MAIL</td>
        <td><input name="email" type="email" /></td>
    </tr>
    <tr>
        <td></td>
        <td><input type="submit" value="Register!" /></td>
    </tr>
</table>

CSS:

table input[type="submit"] {
    display: block;
    margin: 0 auto;
}

In SL5 I found this to work:

<TextBlock Name="textBlock" Text="{Binding JustificationDate, StringFormat=dd-MMMM-yy hh:mm}">
<TextBlock Name="textBlock" Text="{Binding JustificationDate, StringFormat='Justification Date: \{0:dd-MMMM-yy hh:mm\}'}">

My issue got resolved with the help of following steps:

For gradle 3.0.0 and above version

1. add google() below jcenter()
2. Change the compileSdkVersion to 26 and buildToolsVersion to 26.0.2
3. Change to gradle-4.2.1-all.zip in the gradle_wrapper.properties file

Firefox 26 seems to require

page-break-inside: avoid;

And Chrome 32 needs

-webkit-column-break-inside:avoid;
   -moz-column-break-inside:avoid;
        column-break-inside:avoid;

According to Material Guidance; height of status bar is 24 dp.

If you want get status bar height in pixels you can use below method:

private static int statusBarHeight(android.content.res.Resources res) {
    return (int) (24 * res.getDisplayMetrics().density);
}

which can be called from activity with:

statusBarHeight(getResources());

You might want to try the solution from this O'Reilly article.

The important part are these CSS media queries:

Have you included the System.Web assembly in the application?

using System.Web;

If not, try specifying the System.Web namespace, for example:

 System.Web.HttpContext.Current

Try this one:

android.support.v7.app.ActionBar ab = getSupportActionBar();
ab.setTitle("This is Title");
ab.setSubtitle("This is Subtitle");

As already mentioned the C++ way is using stringstreams.

#include <sstream>

string a = "test";
string b = "text.txt";
string c = "text1.txt";

std::stringstream ostr;
ostr << a << " " << b << " > " << c;

Note that you can get the C string from the string stream object like so.

std::string formatted_string = ostr.str();
const char* c_str = formatted_string.c_str();

I'm a novice, but it helped me.

There's no clean way I could find, but here's a hack...

1) I noticed that the mouseover event happens prior to the zoom, but the zoom happens before mousedown or focus events.

2) You can dynamically change the META viewport tag using javascript (see Enable/disable zoom on iPhone safari with Javascript?)

So, try this (shown in jquery for compactness):

$("input[type=text], textarea").mouseover(zoomDisable).mousedown(zoomEnable);
function zoomDisable(){
  $('head meta[name=viewport]').remove();
  $('head').prepend('<meta name="viewport" content="user-scalable=0" />');
}
function zoomEnable(){
  $('head meta[name=viewport]').remove();
  $('head').prepend('<meta name="viewport" content="user-scalable=1" />');
}

This is definitely a hack... there may be situations where mouseover/down don't always catch entries/exits, but it worked well in my tests and is a solid start.

Please use view.getLocationOnScreen(int[] location); (see Javadocs). The answer is in the integer array (x = location[0] and y = location[1]).

$post_data = [
  "item" => [
    'item_type_id' => $item_type,
    'string_key' => $string_key,
    'string_value' => $string_value,
    'string_extra' => $string_extra,
    'is_public' => $public,
    'is_public_for_contacts' => $public_contacts
  ]
];

$post_data = json_encode(post_data);
$post_data = json_decode(post_data);
return $post_data;

If your RESTFul call sends XML Messages back and forth embedded in the Html Body of the HTTP request, you should be able to have all the benefits of WS-Security such as XML encryption, Cerificates, etc in your XML messages while using whatever security features are available from http such as SSL/TLS encryption.

I had this problem resolved. Aparently that message is used in multiple error types. My problem was that i had reached my maximum of 500 sent mails.

log into the account and manually try to send a mail. If the limit has been reached it will inform you

You can use getEventListeners in your Google Chrome developer console.

getEventListeners(object) returns the event listeners registered on the specified object.

getEventListeners(document.querySelector('option[value=Closed]'));

In your example, the TMP variable is set (and the temporary directory created) whenever the rules for out.tar are evaluated. In order to create the directory only when out.tar is actually fired, you need to move the directory creation down into the steps:

out.tar : 
    $(eval TMP := $(shell mktemp -d))
    @echo hi $(TMP)/hi.txt
    tar -C $(TMP) cf $@ .
    rm -rf $(TMP)

The eval function evaluates a string as if it had been typed into the makefile manually. In this case, it sets the TMP variable to the result of the shell function call.

edit (in response to comments):

To create a unique variable, you could do the following:

out.tar : 
    $(eval $@_TMP := $(shell mktemp -d))
    @echo hi $($@_TMP)/hi.txt
    tar -C $($@_TMP) cf $@ .
    rm -rf $($@_TMP)

This would prepend the name of the target (out.tar, in this case) to the variable, producing a variable with the name out.tar_TMP. Hopefully, that is enough to prevent conflicts.

The method has been renamed to findById(…) returning an Optional so that you have to handle absence yourself:

Optional<Foo> result = repository.findById(…);

result.ifPresent(it -> …); // do something with the value if present
result.map(it -> …); // map the value if present
Foo foo = result.orElse(null); // if you want to continue just like before

Do you mean something like this:

HTML

<div class="row">
  <div class="container">

    <div class="col-md-4">
      left content
    </div>

    <div class="col-md-4 col-md-offset-4">

      <div class="yellow-background">
        text
        <div class="pull-right">right content</div>  
      </div>

    </div>
  </div>
</div>

CSS

.yellow-background {
  background: blue;
}

.pull-right {
  background: yellow;
}

A full example can be found on Codepen.

I had this issue , When calling Generic.List like:

mylist.Select( selectFunc )

Where selectFunc is defined as Expression<Func<T, List<string>>>. Simply changed "mylist" to be a IQuerable instead of List then it allowed me to use .Select.

You should look at using the System.Data.SqlClient.SqlBulkCopy for this. Here's the documentation, and of course there are plenty of tutorials online.

Sorry, I know you were looking for a simple answer to get EF to do what you want, but bulk operations are not really what ORMs are meant for.

The type attribute is used to define the MIME type within the HTML document. Depending on what DOCTYPE you use, the type value is required in order to validate the HTML document.

The language attribute lets the browser know what language you are using (Javascript vs. VBScript) but is not necessarily essential and, IIRC, has been deprecated.

if hostname does not work, try IP address.

This is going on right now so I have to say. I try to ssh with my host name and it does not work

ssh [email protected]

this gives the error "ssh_exchange_identification: Connection closed by remote host"

this USED to work one hour back.

BUT, and here is the interesting part, the IP address works!

ssh [email protected]

(of course the actual IP address is different)

Go figure!

For small files, you may consider using more_itertools.seekable - a third-party tool that offers resetting iterables.

Demo

import csv

import more_itertools as mit


filename = "data/iris.csv"
with open(filename, "r") as f:
    reader = csv.DictReader(f)
    iterable = mit.seekable(reader)                    # 1
    print(next(iterable))                              # 2
    print(next(iterable))
    print(next(iterable))

    print("\nReset iterable\n--------------")
    iterable.seek(0)                                   # 3
    print(next(iterable))
    print(next(iterable))
    print(next(iterable))

Output

{'Sepal width': '3.5', 'Petal width': '0.2', 'Petal length': '1.4', 'Sepal length': '5.1', 'Species': 'Iris-setosa'}
{'Sepal width': '3', 'Petal width': '0.2', 'Petal length': '1.4', 'Sepal length': '4.9', 'Species': 'Iris-setosa'}
{'Sepal width': '3.2', 'Petal width': '0.2', 'Petal length': '1.3', 'Sepal length': '4.7', 'Species': 'Iris-setosa'}

Reset iterable
--------------
{'Sepal width': '3.5', 'Petal width': '0.2', 'Petal length': '1.4', 'Sepal length': '5.1', 'Species': 'Iris-setosa'}
{'Sepal width': '3', 'Petal width': '0.2', 'Petal length': '1.4', 'Sepal length': '4.9', 'Species': 'Iris-setosa'}
{'Sepal width': '3.2', 'Petal width': '0.2', 'Petal length': '1.3', 'Sepal length': '4.7', 'Species': 'Iris-setosa'}

Here a DictReader is wrapped in a seekable object (1) and advanced (2). The seek() method is used to reset/rewind the iterator to the 0th position (3).

Note: memory consumption grows with iteration, so be wary applying this tool to large files, as indicated in the docs.

to refresh the form you need to type - me.refresh in the button event on click

use this..

$(".content_box a:not('.button')")

To separate by tabs:

$comp = preg_split("/[\t]/", $var);

To separate by spaces/tabs/newlines:

$comp = preg_split('/\s+/', $var);

To seperate by spaces alone:

$comp = preg_split('/ +/', $var);

The accepted answer is the correct one.

OTOH, the way I previously solved this was to add the following to all projects:

test.onlyIf { ! Boolean.getBoolean('skip.tests') }

Run the build with -Dskip.tests=true and all test tasks will be skipped.

Just as a tidbit:

Even (((A)null)instanceof A) will return false.

(If typecasting null seems surprising, sometimes you have to do it, for example in situations like this:

public class Test
{
  public static void test(A a)
  {
    System.out.println("a instanceof A: " + (a instanceof A));
  }

  public static void test(B b) {
    // Overloaded version. Would cause reference ambiguity (compile error)
    // if Test.test(null) was called without casting.
    // So you need to call Test.test((A)null) or Test.test((B)null).
  }
}

So Test.test((A)null) will print a instanceof A: false.)

P.S.: If you are hiring, please don't use this as a job interview question. :D

If you are using Samsung Device and by any chance marked your app for Samsung Knox, then you need to uninstall it from My Knox app.

Uninstalling just from General apps won't uninstall it from Knox App. It has to be done explicitly!

In my case I wanted to center my logo on a website when the browser has 800px or less, then I did this by using the @media tag:

@media screen and (max-width: 800px) {
  #logo {
    float: none;
    margin: 0;
    text-align: center;
    display: block;
    width: auto;
  }
}

It worked for me, hope somebody find this solution useful. :) For more information see this.

in your Product Web API controller:

[RoutePrefix("api/product")]
public class ProductController : ApiController
{
    private readonly IProductRepository _repository;
    public ProductController(IProductRepository repository)
    {
        this._repository = repository;
    }

    [HttpGet, Route("orders")]
    public async Task<IHttpActionResult> GetProductPeriodOrders(string productCode, DateTime dateStart, DateTime dateEnd)
    {
        try
        {
            IList<Order> orders = await _repository.GetPeriodOrdersAsync(productCode, dateStart.ToUniversalTime(), dateEnd.ToUniversalTime());
            return Ok(orders);
        }
        catch(Exception ex)
        {
            return NotFound();
        }
    }
}

test GetProductPeriodOrders method in Fiddler - Composer:

http://localhost:46017/api/product/orders?productCode=100&dateStart=2016-12-01T00:00:00&dateEnd=2016-12-31T23:59:59

DateTime format:

yyyy-MM-ddTHH:mm:ss

javascript pass parameter use moment.js

const dateStart = moment(startDate).format('YYYY-MM-DDTHH:mm:ss');
const dateEnd = moment(endDate).format('YYYY-MM-DDTHH:mm:ss');

Your calculation is correct for DATE types, but if your values are timestamps, you should probably use EXTRACT (or DATE_PART) to be sure to get only the difference in full days;

EXTRACT(DAY FROM MAX(joindate)-MIN(joindate)) AS DateDifference

An SQLfiddle to test with. Note the timestamp difference being 1 second less than 2 full days.

to escape non-alphanumeric characters of string variables, including dots, you could use re.escape:

import re

expression = 'whatever.v1.dfc'
escaped_expression = re.escape(expression)
print(escaped_expression)

output:

whatever\.v1\.dfc

you can use the escaped expression to find/match the string literally.

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

return false in your listener should work in all browsers.

$('orderNowForm').addEvent('submit', function () {
    // your code
    return false;
}

This solved my problem when I had to deal with HTML page with embedded JavaScript

WebElement empSalary =  driver.findElement(By.xpath(PayComponentAmount));
Actions mouse2 = new Actions(driver);
mouse2.clickAndHold(empSalary).sendKeys(Keys.chord(Keys.CONTROL, "a"), "1234").build().perform();

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].onchange()", empSalary);

Works for me perfect:

    values.put(DBHelper.COLUMN_RECEIVEDATE, geo.getReceiveDate().getTime());

Save your date as a long.

To call a controller function in parent scope from inside an isolate scope directive, use dash-separated attribute names in the HTML like the OP said.

Also if you want to send a parameter to your function, call the function by passing an object:

<test color1="color1" update-fn="updateFn(msg)"></test>

JS

var app = angular.module('dr', []);

app.controller("testCtrl", function($scope) {
    $scope.color1 = "color";
    $scope.updateFn = function(msg) {        
        alert(msg);
    }
});

app.directive('test', function() {
    return {
        restrict: 'E',
        scope: {
            color1: '=',
            updateFn: '&'
        },
        // object is passed while making the call
        template: "<button ng-click='updateFn({msg : \"Hello World!\"})'>
            Click</button>",
        replace: true,        
        link: function(scope, elm, attrs) {             
        }
    }
});

Fiddle

The choice of one or another depends on what you intend to do. From what I do understand:

• jsonify would be useful when you are building an API someone would query and expect json in return. E.g: The REST github API could use this method to answer your request.

• dumps, is more about formating data/python object into json and work on it inside your application. For instance, I need to pass an object to my representation layer where some javascript will display graph. You'll feed javascript with the Json generated by dumps.

From the git-branch manual page:

 git branch --contains <commit>

Only list branches which contain the specified commit (HEAD if not specified). Implies --list.

 git branch -r --contains <commit>

Lists remote tracking branches as well (as mentioned in user3941992's answer below) that is "local branches that have a direct relationship to a remote branch".

As noted by Carl Walsh, this applies only to the default refspec

fetch = +refs/heads/*:refs/remotes/origin/*

If you need to include other ref namespace (pull request, Gerrit, ...), you need to add that new refspec, and fetch again:

git config --add remote.origin.fetch "+refs/pull/*/head:refs/remotes/origin/pr/*"
git fetch
git branch -r --contains <commit>

See also this git ready article.

The --contains tag will figure out if a certain commit has been brought in yet into your branch. Perhaps you’ve got a commit SHA from a patch you thought you had applied, or you just want to check if commit for your favorite open source project that reduces memory usage by 75% is in yet.

MatrixFrog comments that it only shows which branches contain that exact commit.
If you want to know which branches contain an "equivalent" commit (i.e. which branches have cherry-picked that commit) that's git cherry:

Because git cherry compares the changeset rather than the commit id (sha1), you can use git cherry to find out if a commit you made locally has been applied <upstream> under a different commit id.
For example, this will happen if you’re feeding patches <upstream> via email rather than pushing or pulling commits directly.

           __*__*__*__*__> <upstream>
          /
fork-point
          \__+__+__-__+__+__-__+__> <head>

(Here, the commits marked '-' wouldn't show up with git cherry, meaning they are already present in <upstream>.)

When we talk of Tiers, we generally talk of Physical Processes (having different memory space).

Thus, in case, Layers of an application are deployed in different processes, those different processes will be different tiers.

E.g, In a 3-tier application, business tier talks to Mainframes (separate process) and talks to Reporting Service (separate process), then that application would be 5 tier.

Hence, the generic name is n-tier.

We've seen in our projects that a post request with JSON and files is creating a lot of confusion between the frontend and backend developers, leading to unnecessary wastage of time.

Here's a better approach: convert file bytes array to Base64 string and send it in the JSON.

public Class UserDTO {
    private String firstName;
    private String lastName;
    private FileDTO profilePic; 
}

public class FileDTO {
    private String base64;
    // just base64 string is enough. If you want, send additional details
    private String name;
    private String type;
    private String lastModified;
}

@PostMapping("/user")
public String saveUser(@RequestBody UserDTO user) {
    byte[] fileBytes = Base64Utils.decodeFromString(user.getProfilePic().getBase64());
    ....
}

JS code to convert file to base64 string:

var reader = new FileReader();
reader.readAsDataURL(file);
reader.onload = function () {

  const userDTO = {
    firstName: "John",
    lastName: "Wick",
    profilePic: {
      base64: reader.result,
      name: file.name,
      lastModified: file.lastModified,
      type: file.type
    }
  }
  
  // post userDTO
};
reader.onerror = function (error) {
  console.log('Error: ', error);
};

Other options, instead of using a custom XML file, we can use a more user friendly file format: JSON or YAML file.

• If you use .NET 4.0 dynamic, this library is really easy to use (serialize, deserialize, nested objects support and ordering output as you wish + merging multiple settings to one) JsonConfig (usage is equivalent to ApplicationSettingsBase)
• For .NET YAML configuration library... I haven't found one that is as easy to use as JsonConfig

You can store your settings file in multiple special folders (for all users and per user) as listed here Environment.SpecialFolder Enumeration and multiple files (default read only, per role, per user, etc.)

• Sample for getting path of special folder: C# getting the path of %AppData%

If you choose to use multiple settings, you can merge those settings: For example, merging settings for default + BasicUser + AdminUser. You can use your own rules: the last one overrides the value, etc.

raw.github.com is not truely raw access to file asset, but a view rendered by Rails. So accessing raw.github.com is much heavier than needed. I don't know why raw.github.com is implemented as a Rails view. Instead of fix this route issue, GitHub added a X-Content-Type-Options: nosniff header.

Workaround:

• Put the script to user.github.io/repo
• Use a third party CDN like rawgit.com.

This problem is quite annoying. I usually have Chinese character in my filename and file content. Please note that I am using Windows 10, here is my solution:

To display the file name, such as dir or ls if you installed Ubuntu bash on Windows 10

1. Set the region to support non-utf 8 character.

2. After that, console's font will be changed to the font of that locale, and it also changes the encoding of the console.

After you have done previous steps, in order to display the file content of a UTF-8 file using command line tool

1. Change the page to utf-8 by chcp 65001
2. Change to the font that supports utf-8, such as Lucida Console
3. Use type command to peek the file content, or cat if you installed Ubuntu bash on Windows 10
4. Please note that, after setting the encoding of the console to utf-8, I can't type Chinese character in the cmd using Chinese input method.

The laziest solution: Just use a console emulator such as http://cmder.net/

Just adding the #include <math.h> in c source file and -lm in Makefile at the end will work for me.

    gcc -pthread -o p3 p3.c -lm

You have to use CASE Statement/Expression

Select * from Customer
WHERE  (I.IsClose=@ISClose OR @ISClose is NULL)  
AND    
    (C.FirstName like '%'+@ClientName+'%' or @ClientName is NULL )    
AND 
     CASE @Value
         WHEN 2 THEN (CASE I.RecurringCharge WHEN @Total or @Total is NULL) 
         WHEN 3 THEN (CASE WHEN I.RecurringCharge like 
                               '%'+cast(@Total as varchar(50))+'%' 
                     or @Total is NULL )
     END

x86 is a family of backward-compatible instruction set architectures based on the Intel 8086 CPU and its Intel 8088 variant.

An instruction set architecture (ISA) is an abstract model of a computer. It is also referred to as architecture or computer architecture.

A realization of an ISA is called an implementation. An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.

Software that has been written for an ISA can run on different implementations of the same ISA (Exp: 32bit or 64bit). This has enabled binary compatibility between different generations of computers to be easily achieved, and the development of computer families.

Both of these developments have helped to lower the cost of computers and to increase their applicability. For these reasons, the ISA is one of the most important abstractions in computing today.
