What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

What is the difference between them?

Image: the generic Linux kernel binary image file.

zImage: a compressed version of the Linux kernel image that is self-extracting.

uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.

Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:

Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.

(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)

Which type of kernel image do I have to use?

You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.

ADDENDUM

I know that u-boot needs a kernel in uImage format.

That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.

Check if you have the window var in the AppDelegate.

var window: UIWindow? 

And also check the storyboard of your Info.plist file.

<key>UIMainStoryboardFile</key>
<string>Main</string>

Programmatically setting the rootViewController in the AppDelegate is not going to fix the warning. You should choose whether to let to the storyboard set the view controller or do it programmatically.

Check your folder's permission where the image is saved Right cLick on folder then go :

Properties > Security > Edit > Add-- select "everyone" and check Allow "Full Control"

For those who are trying to get an X Window application working from Windows from Linux:

What worked for me was to setup xming server on my windows machine, set X11 forwarding option in putty when I connect to the linux host and put in my windows ip address with the display port and then the display variable with my windows IP address:0.0

Dont forget to add the linux hosts IP address to the X0.hosts file to ensure that the xming server accepts traffic from that host. Took me a while to figure that out.

This assumes Eclipse and an appropriate JDK are installed on your system

1. Open Eclipse and create a new Workspace by specifying an empty directory.
2. Make sure you're in the Java perspective by selecting Window -> Open Perspective ..., select Other... and then Java
3. Right click anywhere in the Package Explorer pane and select New -> Java Project
4. In the dialog that opens give the project a name and then click the option that says "Crate project from existing sources."
5. In the text box below the option you selected in Step 4 point to the root directory where you checked out the project. This should be the directory that contains "com"
6. Click Finish. For this particular project you don't need to do any additional setup for your classpath since it only depends on classes that are part of the Java SE API.

array_values does the job :

$myArray  = array_values($myArray);

Also some other php function do not preserve the keys, i.e. reset the index.

You may need to run the cron job as a user with permissions to execute the PHP script. Try executing the cron job as root, using the command runuser (man runuser). Or create a system crontable and run the PHP script as an authorized user, as @Philip described.

I provide a detailed answer how to use cron in this stackoverflow post.

How to write a cron that will run a script every day at midnight?

Here's a slightly more concise version of @vbem's solution:

from datetime import datetime as dt

dt.utcnow().astimezone().tzinfo

The only substantive difference is that I replaced datetime.datetime.now(datetime.timezone.utc) with datetime.datetime.utcnow(). For brevity, I also aliased datetime.datetime as dt.

For my purposes, I want the UTC offset in seconds. Here's what that looks like:

dt.utcnow().astimezone().utcoffset().total_seconds()

The reason why we have stdClass is because in PHP there is no way to distinguish a normal array from an associate array (like in Javascript you have {} for object and [] for array to distinguish them).

So this creates a problem for empty objects. Take this for example.

PHP:

$a = [1, 2, 3]; // this is an array
$b = ['one' => 1, 'two' => 2]; // this is an associate array (aka hash)
$c = ['a' => $a, 'b' => $b]; // this is also an associate array (aka hash)

Let's assume you want to JSON encode the variable $c

echo json_encode($c);
// outputs => {'a': [1,2,3], 'b': {one: 1, two: 2}}

Now let's say you deleted all the keys from $b making it empty. Since $b is now empty (you deleted all the keys remember?), it looks like [] which can be either an array or object if you look at it.

So if you do a json_encode again, the output will be different

echo json_encode($c);
// outputs => {'a': [1,2,3], 'b': []}

This is a problem because we know b that was supposed to be an associate array but PHP (or any function like json_encode) doesn't.

So stdClass comes to rescue. Taking the same example again

$a = [1, 2, 3]; // this is an array
$b = (object) ['one' => 1, 'two' => 2]; // this makes it an stdClass
$c = ['a' => $a, 'b' => $b]; // this is also an associate array (aka hash)

So now even if you delete all keys from $b and make it empty, since it is an stdClass it won't matter and when you json_encode it you will get this:

echo json_encode($c);
// outputs => {'a': [1,2,3], 'b': {}}

This is also the reason why json_encode and json_decode by default return stdClass.

 $c = json_decode('{"a": [1,2,3], "b": {}}', true); //true to deocde as array
 // $c is now ['a' => [1,2,3], 'b' => []] in PHP
 // if you json_encode($c) again your data is now corrupted

Given a list:

var list = new List<Child>()
{
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "John"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Bob", Name = "Pete"},
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "Fred"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Fred", Name = "Bob"},
};

The query would look like:

var newList = list
    .GroupBy(x => new {x.School, x.Friend, x.FavoriteColor})
    .Select(y => new ConsolidatedChild()
        {
            FavoriteColor = y.Key.FavoriteColor,
            Friend = y.Key.Friend,
            School = y.Key.School,
            Children = y.ToList()
        }
    );

Test code:

foreach(var item in newList)
{
    Console.WriteLine("School: {0} FavouriteColor: {1} Friend: {2}", item.School,item.FavoriteColor,item.Friend);
    foreach(var child in item.Children)
    {
        Console.WriteLine("\t Name: {0}", child.Name);
    }
}

Result:

School: School1 FavouriteColor: blue Friend: Bob
    Name: John
    Name: Fred
School: School2 FavouriteColor: blue Friend: Bob
    Name: Pete
School: School2 FavouriteColor: blue Friend: Fred
    Name: Bob

Here is my modification of the currently accepted answer, which I believe it's a little faster and shorter:

private static Random random = new Random();

private string RandomString(int size) {
    StringBuilder builder = new StringBuilder(size);
    for (int i = 0; i < size; i++)
        builder.Append((char)random.Next(0x41, 0x5A));
    return builder.ToString();
}

Notice I didn't use all the multiplication, Math.floor(), Convert etc.

EDIT: random.Next(0x41, 0x5A) can be changed to any range of Unicode characters.

You have to install a ProxyHandler

urllib2.install_opener(
    urllib2.build_opener(
        urllib2.ProxyHandler({'http': '127.0.0.1'})
    )
)
urllib2.urlopen('http://www.google.com')

Format your string like so:

[#                    ] 1%\r

Note the \r character. It is the so-called carriage return that will move the cursor back to the beginning of the line.

Finally, make sure you use

System.out.print()

and not

System.out.println()

There are many anwers in this question, probably all will give you the answer you are looking for. But as @TallGreenTree mentions, there is a function for this.

But the problem of the answer of @TallGreenTree is that it doesn't round up, it rounds to the nearest 10. To solve this, add +5 to your number in order to round up. If you want to round down, do -5.

So in code:

round($num + 5, -1);

You can't use the round mode for rounding up, because that only rounds up fractions and not whole numbers.

If you want to round up to the nearest 100, you shoud use +50.

The accepted solution only works on arrays, but not objects or associative arrays. Unfortunately, since Angular depends on the JavaScript implementation of array enumeration, the order of object properties cannot be consistently controlled. Some browsers may iterate through object properties lexicographically, but this cannot be guaranteed.

e.g. Given the following assignment:

$scope.cards = {
  "card2": {
    values: {
      opt1: 9,
      opt2: 12
    }
  },
  "card1": {
    values: {
      opt1: 9,
      opt2: 11
    }
  }
};

and the directive <ul ng-repeat="(key, card) in cards | orderBy:myValueFunction">, ng-repeat may iterate over "card1" prior to "card2", regardless of sort order.

To workaround this, we can create a custom filter to convert the object to an array, and then apply a custom sort function before returning the collection.

myApp.filter('orderByValue', function () {
  // custom value function for sorting
  function myValueFunction(card) {
    return card.values.opt1 + card.values.opt2;
  }

  return function (obj) {
    var array = [];
    Object.keys(obj).forEach(function (key) {
      // inject key into each object so we can refer to it from the template
      obj[key].name = key;
      array.push(obj[key]);
    });
    // apply a custom sorting function
    array.sort(function (a, b) {
      return myValueFunction(b) - myValueFunction(a);
    });
    return array;
  };
});

We cannot iterate over (key, value) pairings in conjunction with custom filters (since the keys for arrays are numerical indexes), so the template should be updated to reference the injected key names.

<ul ng-repeat="card in cards | orderByValue">
    <li>{{card.name}} {{value(card)}}</li>
</ul>

Here is a working fiddle utilizing a custom filter on an associative array: http://jsfiddle.net/av1mLpqx/1/

This is a bug in .NET. When PowerShell launches, it caches the output handle (Console.Out). The Encoding property of that text writer does not pick up the value StandardOutputEncoding property.

When you change it from within PowerShell, the Encoding property of the cached output writer returns the cached value, so the output is still encoded with the default encoding.

As a workaround, I would suggest not changing the encoding. It will be returned to you as a Unicode string, at which point you can manage the encoding yourself.

Caching example:

102 [C:\Users\leeholm]
>> $r1 = [Console]::Out

103 [C:\Users\leeholm]
>> $r1

Encoding                                          FormatProvider
--------                                          --------------
System.Text.SBCSCodePageEncoding                  en-US



104 [C:\Users\leeholm]
>> [Console]::OutputEncoding = [System.Text.Encoding]::UTF8

105 [C:\Users\leeholm]
>> $r1

Encoding                                          FormatProvider
--------                                          --------------
System.Text.SBCSCodePageEncoding                  en-US

Just add position: fixed; in your div style.

I have checked and Its working fine in my code.

Another way to solve this problem (it's not so good practice but looks beauty):

static class Helper
{
    public static object AsSingleParam(this object[] arg)
    {
       return (object)arg;
    }
}

Usage:

f(new object[] { 1, 2, 3 }.AsSingleParam());

In the model, write the below code;

public $timestamps = false;

This would work.

Explanation : By default laravel will expect created_at & updated_at column in your table. By making it to false it will override the default setting.

Couldn't you just pass the a name attribute and wrap it in a form?

<form id="form" action="do_stuff.php" method="post">
    <select id="select_catalog" name="select_catalog_query">
    <?php <<<INSERT THE SELECT OPTION LOOP>>> ?>
    </select>
</form>

And then look for $_POST['select_catalog_query'] ?

This code works perfectly well:

 Actions builder = new Actions(driver);
 WebElement element = driver.findElement(By.linkText("Put your text here"));
 builder.moveToElement(element).build().perform();

After the mouse over, you can then go on to perform the next action you want on the revealed information

This was added to the upgrade documentation on Dec 29, 2015, so if you upgraded before then you probably missed it.

When fetching any attribute from the model it checks if that column should be cast as an integer, string, etc.

By default, for auto-incrementing tables, the ID is assumed to be an integer in this method:

https://github.com/laravel/framework/blob/5.2/src/Illuminate/Database/Eloquent/Model.php#L2790

So the solution is:

class UserVerification extends Model
{
    protected $primaryKey = 'your_key_name'; // or null

    public $incrementing = false;

    // In Laravel 6.0+ make sure to also set $keyType
    protected $keyType = 'string';
}

Solution 3

This is for using a single directory for multiple projects. I use this technique for some closely related projects where I often need to pull changes from one project into another. It's similar to the orphaned branches idea but the branches don't need to be orphaned. Simply start all the projects from the same empty directory state.

Start all projects from one committed empty directory

Don't expect wonders from this solution. As I see it, you are always going to have annoyances with untracked files. Git doesn't really have a clue what to do with them and so if there are intermediate files generated by a compiler and ignored by your .gitignore file, it is likely that they will be left hanging some of the time if you try rapidly swapping between - for example - your software project and a PH.D thesis project.

However here is the plan. Start as you ought to start any git projects, by committing the empty repository, and then start all your projects from the same empty directory state. That way you are certain that the two lots of files are fairly independent. Also, give your branches a proper name and don't lazily just use "master". Your projects need to be separate so give them appropriate names.

Git commits (and hence tags and branches) basically store the state of a directory and its subdirectories and Git has no idea whether these are parts of the same or different projects so really there is no problem for git storing different projects in the same repository. The problem is then for you clearing up the untracked files from one project when using another, or separating the projects later.

Create an empty repository

cd some_empty_directory
git init
touch .gitignore
git add .gitignore
git commit -m empty
git tag EMPTY

Start your projects from empty.

Work on one project.

git branch software EMPTY
git checkout software
echo "array board[8,8] of piece" > chess.prog

git add chess.prog 
git commit -m "chess program"

Start another project

whenever you like.

git branch thesis EMPTY
git checkout thesis
echo "the meaning of meaning" > philosophy_doctorate.txt
git add philosophy_doctorate.txt 
git commit -m "Ph.D"

Switch back and forth

Go back and forwards between projects whenever you like. This example goes back to the chess software project.

git checkout software
echo "while not end_of_game do make_move()" >> chess.prog
git add chess.prog 
git commit -m "improved chess program"

Untracked files are annoying

You will however be annoyed by untracked files when swapping between projects/branches.

touch untracked_software_file.prog
git checkout thesis 
ls
    philosophy_doctorate.txt  untracked_software_file.prog

It's not an insurmountable problem

Sort of by definition, git doesn't really know what to do with untracked files and it's up to you to deal with them. You can stop untracked files from being carried around from one branch to another as follows.

git checkout EMPTY 
ls
    untracked_software_file.prog
rm -r *
    (directory is now really empty, apart from the repository stuff!)
git checkout thesis
ls
    philosophy_doctorate.txt

By ensuring that the directory was empty before checking out our new project we made sure there were no hanging untracked files from another project.

A refinement

$ GIT_AUTHOR_DATE='2001-01-01:T01:01:01' GIT_COMMITTER_DATE='2001-01-01T01:01:01' git commit -m empty

If the same dates are specified whenever committing an empty repository, then independently created empty repository commits can have the same SHA1 code. This allows two repositories to be created independently and then merged together into a single tree with a common root in one repository later.

Example

# Create thesis repository. 
# Merge existing chess repository branch into it

mkdir single_repo_for_thesis_and_chess
cd single_repo_for_thesis_and_chess
git init
touch .gitignore
git add .gitignore
GIT_AUTHOR_DATE='2001-01-01:T01:01:01' GIT_COMMITTER_DATE='2001-01-01:T01:01:01' git commit -m empty
git tag EMPTY
echo "the meaning of meaning" > thesis.txt
git add thesis.txt
git commit -m "Wrote my PH.D"
git branch -m master thesis

# It's as simple as this ...
git remote add chess ../chessrepository/.git
git fetch chess chess:chess

Result

Use subdirectories per project?

It may also help if you keep your projects in subdirectories where possible, e.g. instead of having files

chess.prog
philosophy_doctorate.txt 

have

chess/chess.prog
thesis/philosophy_doctorate.txt 

In this case your untracked software file will be chess/untracked_software_file.prog. When working in the thesis directory you should not be disturbed by untracked chess program files, and you may find occasions when you can work happily without deleting untracked files from other projects.

Also, if you want to remove untracked files from other projects, it will be quicker (and less prone to error) to dump an unwanted directory than to remove unwanted files by selecting each of them.

Branch names can include '/' characters

So you might want to name your branches something like

project1/master
project1/featureABC
project2/master
project2/featureXYZ

The null keyword is a literal that represents a null reference, one that does not refer to any object. null is the default value of reference-type variables.

Also maybe have a look at

null : Java Glossary

I just modified hhafez's test to include StringBuilder. StringBuilder is 33 times faster than String.format using jdk 1.6.0_10 client on XP. Using the -server switch lowers the factor to 20.

public class StringTest {

   public static void main( String[] args ) {
      test();
      test();
   }

   private static void test() {
      int i = 0;
      long prev_time = System.currentTimeMillis();
      long time;

      for ( i = 0; i < 1000000; i++ ) {
         String s = "Blah" + i + "Blah";
      }
      time = System.currentTimeMillis() - prev_time;

      System.out.println("Time after for loop " + time);

      prev_time = System.currentTimeMillis();
      for ( i = 0; i < 1000000; i++ ) {
         String s = String.format("Blah %d Blah", i);
      }
      time = System.currentTimeMillis() - prev_time;
      System.out.println("Time after for loop " + time);

      prev_time = System.currentTimeMillis();
      for ( i = 0; i < 1000000; i++ ) {
         new StringBuilder("Blah").append(i).append("Blah");
      }
      time = System.currentTimeMillis() - prev_time;
      System.out.println("Time after for loop " + time);
   }
}

While this might sound drastic, I consider it to be relevant only in rare cases, because the absolute numbers are pretty low: 4 s for 1 million simple String.format calls is sort of ok - as long as I use them for logging or the like.

Update: As pointed out by sjbotha in the comments, the StringBuilder test is invalid, since it is missing a final .toString().

The correct speed-up factor from String.format(.) to StringBuilder is 23 on my machine (16 with the -server switch).

I had the same error on OSX Sierra, but in my case the ~/.android folder was owned by root (from a previous install) I changed the ownership to my User and now it works.

Go to project properties -> configurations properties -> C/C++ -> treats warning as error -> No (/WX-).

If on another occasion you're synchronising a Collection rather than a String, perhaps you're be iterating over the collection and are worried about it mutating, Java 5 offers:

• CopyOnWriteArrayList
• CopyOnWriteArraySet

I think you need this ..

Dim n as Integer   

For n = 5 to 17
  msgbox cells(n,3) '--> sched waste
  msgbox cells(n,4) '--> type of treatm
  msgbox format(cells(n,5),"dd/MM/yyyy") '--> Lic exp
  msgbox cells(n,6) '--> email col
Next

using std::string;

string string_replace( string src, string const& target, string const& repl)
{
    // handle error situations/trivial cases

    if (target.length() == 0) {
        // searching for a match to the empty string will result in 
        //  an infinite loop
        //  it might make sense to throw an exception for this case
        return src;
    }

    if (src.length() == 0) {
        return src;  // nothing to match against
    }

    size_t idx = 0;

    for (;;) {
        idx = src.find( target, idx);
        if (idx == string::npos)  break;

        src.replace( idx, target.length(), repl);
        idx += repl.length();
    }

    return src;
}

Since it's not a member of the string class, it doesn't allow quite as nice a syntax as in your example, but the following will do the equivalent:

test = string_replace( string_replace( test, "abc", "hij"), "def", "klm")

Remove "track by index" from the ng-repeat and it would refresh the DOM

As documentation says:

Raised when the part of a "multipart/form-data" request identified by its name cannot be found.

This may be because the request is not a multipart/form-data either because the part is not present in the request, or because the web application is not configured correctly for processing multipart requests -- e.g. no MultipartResolver.

Slight change to the FastArray from above:

'pushtest.vbs
imax = 10000000
value = "Testvalue"
s = imax & " of """ & value & """" 

t0 = timer 'Fast array
a = array()
ub = UBound(a)
For i = 0 To imax
 If i>ub Then 
    ReDim Preserve a(Int((ub+10)*1.1))
    ub = UBound(a)
 End If
 a(i) = value
Next
ReDim Preserve a(i-1)
s = s & "[FastArr " & FormatNumber(timer - t0, 3, -1) & "]"

MsgBox s

There is no point in checking UBound(a) in every cycle of the for if we know exactly when it changes.

I've changed it so that it checks does UBound(a) just before the for starts and then only every time the ReDim is called

On my computer the old method took 7.52 seconds for an imax of 10 millions.

The new method took 5.29 seconds for an imax of also 10 millions, which signifies a performance increase of over 20% (for 10 millions tries, obviously this percentage has a direct relationship to the number of tries)

You can do this

@Html.DropDownList("Sortby", new SelectListItem[] { new SelectListItem() 
  { 

       Text = "Newest to Oldest", Value = "0" }, new SelectListItem() { Text = "Oldest to Newest", Value = "1" } , new
       {
           onchange = @"form.submit();"
       }
})

Someone will give you a better answe than this possibly, but one thing I tend to do is if all my numeric data are int64 or float64 objects, then you can create a dict of the column data types and then use the values to create your list of columns.

So for example, in a dataframe where I have columns of type float64, int64 and object firstly you can look at the data types as so:

DF.dtypes

and if they conform to the standard whereby the non-numeric columns of data are all object types (as they are in my dataframes), then you can do the following to get a list of the numeric columns:

[key for key in dict(DF.dtypes) if dict(DF.dtypes)[key] in ['float64', 'int64']]

Its just a simple list comprehension. Nothing fancy. Again, though whether this works for you will depend upon how you set up you dataframe...

Here is a variation of ben blank's answer, if you don't like tuples.

This saves you a few characters.

var keys = [];
for (var key in sortme) {
  keys.push(key);
}

keys.sort(function(k0, k1) {
  var a = sortme[k0];
  var b = sortme[k1];
  return a < b ? -1 : (a > b ? 1 : 0);
});

for (var i = 0; i < keys.length; ++i) {
  var key = keys[i];
  var value = sortme[key];
  // Do something with key and value.
}

SQL

SQL is used to communicate with a database, it is the standard language for relational database management systems.

In detail Structured Query Language is a special-purpose programming language designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS).

Originally based upon relational algebra and tuple relational calculus, SQL consists of a data definition language and a data manipulation language. The scope of SQL includes data insert, query, update and delete, schema creation and modification, and data access control. Although SQL is often described as, and to a great extent is, a declarative language (4GL), it also includes procedural elements.

PL/SQL

PL/SQL is a combination of SQL along with the procedural features of programming languages. It was developed by Oracle Corporation

Specialities of PL/SQL

• completely portable, high-performance transaction-processing language.
• provides a built-in interpreted and OS independent programming environment.
• directly be called from the command-line SQL*Plus interface.
• Direct call can also be made from external programming language calls to database.
• general syntax is based on that of ADA and Pascal programming language.
• Apart from Oracle, it is available in TimesTen in-memory database and IBM DB2.

T-SQL

Short for Transaction-SQL, an extended form of SQL that adds declared variables, transaction control, error and exceptionhandling and row processing to SQL

The Structured Query Language or SQL is a programming language that focuses on managing relational databases. SQL has its own limitations which spurred the software giant Microsoft to build on top of SQL with their own extensions to enhance the functionality of SQL. Microsoft added code to SQL and called it Transact-SQL or T-SQL. Keep in mind that T-SQL is proprietary and is under the control of Microsoft while SQL, although developed by IBM, is already an open format.

T-SQL adds a number of features that are not available in SQL.

This includes procedural programming elements and a local variable to provide more flexible control of how the application flows. A number of functions were also added to T-SQL to make it more powerful; functions for mathematical operations, string operations, date and time processing, and the like. These additions make T-SQL comply with the Turing completeness test, a test that determines the universality of a computing language. SQL is not Turing complete and is very limited in the scope of what it can do.

Another significant difference between T-SQL and SQL is the changes done to the DELETE and UPDATE commands that are already available in SQL. With T-SQL, the DELETE and UPDATE commands both allow the inclusion of a FROM clause which allows the use of JOINs. This simplifies the filtering of records to easily pick out the entries that match a certain criteria unlike with SQL where it can be a bit more complicated.

Choosing between T-SQL and SQL is all up to the user. Still, using T-SQL is still better when you are dealing with Microsoft SQL Server installations. This is because T-SQL is also from Microsoft, and using the two together maximizes compatibility. SQL is preferred by people who have multiple backends.

I can think of three options:

Implement RFC 2217

RFC 2217 covers a com port to TCP/IP standard that allows a client on one system to emulate a serial port to the local programs, while transparently sending and receiving data and control signals to a server on another system which actually has the serial port. Here's a high-level overview.

What you would do is find or implement a client com port driver that would implement the client side of the system on your PC - appearing to be a real serial port but in reality shuttling everything to a server. You might be able to get this driver for free from Digi, Lantronix, etc in support of their real standalone serial port servers.

You would then implement the server side of the connection locally in another program - allowing the client to connect and issuing the data and control commands as needed.

It's probably non trivial, but the RFC is out there, and you might be able to find an open source project that implements one or both sides of the connection.

Modify the linux serial port driver

Alternately, the serial port driver source for Linux is readily available. Take that, gut the hardware control pieces, and have that one driver run two /dev/ttySx ports, as a simple loopback. Then connect your real program to the ttyS2 and your simulator to the other ttySx.

Use two USB<-->Serial cables in a loopback

But the easiest thing to do right now? Spend $40 on two serial port USB devices, wire them together (null modem) and actually have two real serial ports - one for the program you're testing, one for your simulator.

Performance

There are already good answer for this question, but I was curious about performance and today 2020.09.21 I conduct tests on MacOs HighSierra 10.13.6 on Chrome v85, Safari v13.1.2 and Firefox v80 for chosen solutions.

Results

• eval/Function (A,B,C) approach is fast on Chrome (but for big-deep object N=1000 they crash: "maximum stack call exceed)
• eval (A) is fast/medium fast on all browsers
• JSON.parse (D,E) are fastest on Safari and Firefox

Details

I perform 4 tests cases:

• for small shallow object HERE
• for small deep object HERE
• for big shallow object HERE
• for big deep object HERE

Object used in above tests came from HERE

let obj_ShallowSmall = {
  field0: false,
  field1: true,
  field2: 1,
  field3: 0,
  field4: null,
  field5: [],
  field6: {},
  field7: "text7",
  field8: "text8",
}

let obj_DeepSmall = {
  level0: {
   level1: {
    level2: {
     level3: {
      level4: {
       level5: {
        level6: {
         level7: {
          level8: {
           level9: [[[[[[[[[['abc']]]]]]]]]],
  }}}}}}}}},
};

let obj_ShallowBig = Array(1000).fill(0).reduce((a,c,i) => (a['field'+i]=getField(i),a) ,{});


let obj_DeepBig = genDeepObject(1000);

And here are example results for chrome

IEnumerable is refering to a collection but IQueryable is just a query and it will be generated inside a Expression Tree.we will run this query to get data from database.

You don't need the 'values' clause when using a 'select' as your source.

insert into table1 (col1, col2) 
select t1.col1, t2.col2 from oldtable1 t1, oldtable2 t2;

You can use XMLHttpRequest, fetch API, ...

If you want to use XMLHttpRequest you can do the following

var xhr = new XMLHttpRequest();
xhr.open("POST", url, true);
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.send(JSON.stringify({
    name: "Deska",
    email: "[email protected]",
    phone: "342234553"
 }));
xhr.onload = function() {
    var data = JSON.parse(this.responseText);
    console.log(data);
};

Or if you want to use fetch API

fetch(url, {
    method:"POST",
    body: JSON.stringify({
        name: "Deska",
        email: "[email protected]",
        phone: "342234553"
        })
    })
    .then(result => {
        // do something with the result
        console.log("Completed with result:", result);
    });

Add permission

<uses-permission android:name="android.permission.INTERNET"/>

And execute :

 new DownloadImageTask(context, imageViewToLoad, urlToImage).execute();

Note that callback syntax is deprecated:

Deprecation Notice

The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callback methods introduced in jQuery 1.5 are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

Here a modernized solution using the promise interface

$.ajax({url: "...", cache: false}).done(function( data ) {
    // data contains result
}).fail(function(err){
    // error
});

The ComboBox control inherits from the ListControl control.

The SelectedItem property is a proper member of the ComboBox control. The event that is fired on change is ComboBox.SelectionChangeCommitted

ComboBox.SelectionChangeCommitted

Occurs when the selected item has changed and that change is displayed in the ComboBox.

The SelectedValue property is inherited from the ListControl control. As such, this property will fire the ListControl.SelectedValueChanged event.

ListControl.SelectedValueChanged

Occurs when the SelectedValue property changes.

That said, they won't fire the INotifyPropertyChanged.PropertyChanged event the same, but they will anyway. The only difference is in the firing event. SelectedValueChanged is fired as soon as a new selection is made from the list part of the ComboBox, and SelectedItemChanged is fired when the item is displayed in the TextBox portion of the ComboBox.

In short, they both represent something in the list part of the ComboBox. So, when binding either property, the result is the same, since the PropertyChanged event is fired in either case. And since they both represent an element from the list, the they are probably treated the same.

Does this help?

EDIT #1

Assuming that the list part of the ComboBox represents a property (as I can't confirm since I didn't write the control), binding either of SelectedItem or SelectedValue affects the same collection inside the control. Then, when this property is changed, the same occurs in the end. The INotifyPropertryPropertyChanged.PropertyChanged event is fired on the same property.

You can simply use core javascript to get the param's key value as a js object:

var url_string = "http://www.example.com/t.html?a=1&b=3&c=m2-m3-m4-m5";
var url = new URL(url_string);
let obj = {};
var c = url.searchParams.forEach((value, key) => {
  obj[key] = value;
});
console.log(obj);

I had a very similar problem, I had an array ready to be posted. in my post function I had this:

json = JSON.stringfy(json);

the detail here is that I'm using blade inside laravel to build a three view form, so I can go back and forward, I have in between every back and forward button validations and when I go back in the form without reloading the page my json get filled by backslashes. I console.log(json) in every validation and realized that the json was treated as a string instead of an object.

In conclution i shouldn't have assinged json = JSON.stringfy(json) instead i assigned it to another variable.

var aux = JSON.stringfy(json);

This way i keep json as an object, and not a string.

If you haven't installed matplotlib yet just try the command.

The histogram data:

plot.hist(weightList,density=1, bins=20) 
plot.axis([50, 110, 0, 0.06])

plot.xlabel('Weight')
plot.ylabel('Probability')

Display histogram

plot.show()

And the output is like :

Didn't quite see this variation in the answers yet. I had an additional constraint where I needed, given an initial seed, to select the same set of rows each time.

For MS SQL:

Minimum example:

select top 10 percent *
from table_name
order by rand(checksum(*))

Normalized execution time: 1.00

NewId() example:

select top 10 percent *
from table_name
order by newid()

Normalized execution time: 1.02

NewId() is insignificantly slower than rand(checksum(*)), so you may not want to use it against large record sets.

Selection with Initial Seed:

declare @seed int
set @seed = Year(getdate()) * month(getdate()) /* any other initial seed here */

select top 10 percent *
from table_name
order by rand(checksum(*) % @seed) /* any other math function here */

If you need to select the same set given a seed, this seems to work.

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]

As Answered here

Use below code :

TelephonyManager tMgr = (TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();

In AndroidManifest.xml, give the following permission:

 <uses-permission android:name="android.permission.READ_PHONE_STATE"/> 

But remember, this code does not always work, since Cell phone number is dependent on the SIM Card and the Network operator / Cell phone carrier.

Also, try checking in Phone--> Settings --> About --> Phone Identity, If you are able to view the Number there, the probability of getting the phone number from above code is higher. If you are not able to view the phone number in the settings, then you won't be able to get via this code!

Suggested Workaround:

1. Get the user's phone number as manual input from the user.
2. Send a code to the user's mobile number via SMS.
3. Ask user to enter the code to confirm the phone number.
4. Save the number in sharedpreference.

Do the above 4 steps as one time activity during the app's first launch. Later on, whenever phone number is required, use the value available in shared preference.

For me I quit Skype, which was occupying port 80, then Apache ran happily on port 80, than I ran Skype and it picked another port this time.

Sure you can:

TLDR; Uninstall and re-install using admin account.

I encountered this error after installing Oracle Express 11g 64 bit using a standard account. After looking for a fix on various sites I realized that the issue was most likely caused by an incorrect setting. Different people suggested editing various files which I was not interested in doing. I found one person who claimed that the issue was a registry setting. Since I used a standard account to install I thought that maybe the registry setting could not be altered using a standard account. So I uninstalled and re-installed using an admin account and it just worked.

Fast-forward merging makes sense for short-lived branches, but in a more complex history, non-fast-forward merging may make the history easier to understand, and make it easier to revert a group of commits.

Warning: Non-fast-forwarding has potential side effects as well. Please review https://sandofsky.com/blog/git-workflow.html, avoid the 'no-ff' with its "checkpoint commits" that break bisect or blame, and carefully consider whether it should be your default approach for master.

^{(From nvie.com, Vincent Driessen, post "A successful Git branching model")}

Incorporating a finished feature on develop

Finished features may be merged into the develop branch to add them to the upcoming release:

$ git checkout develop
Switched to branch 'develop'
$ git merge --no-ff myfeature
Updating ea1b82a..05e9557
(Summary of changes)
$ git branch -d myfeature
Deleted branch myfeature (was 05e9557).
$ git push origin develop

The --no-ff flag causes the merge to always create a new commit object, even if the merge could be performed with a fast-forward. This avoids losing information about the historical existence of a feature branch and groups together all commits that together added the feature.

Jakub Narebski also mentions the config merge.ff:

By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded.
When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line).
When set to 'only', only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line).

The fast-forward is the default because:

• short-lived branches are very easy to create and use in Git
• short-lived branches often isolate many commits that can be reorganized freely within that branch
• those commits are actually part of the main branch: once reorganized, the main branch is fast-forwarded to include them.

But if you anticipate an iterative workflow on one topic/feature branch (i.e., I merge, then I go back to this feature branch and add some more commits), then it is useful to include only the merge in the main branch, rather than all the intermediate commits of the feature branch.

In this case, you can end up setting this kind of config file:

[branch "master"]
# This is the list of cmdline options that should be added to git-merge 
# when I merge commits into the master branch.

# The option --no-commit instructs git not to commit the merge
# by default. This allows me to do some final adjustment to the commit log
# message before it gets commited. I often use this to add extra info to
# the merge message or rewrite my local branch names in the commit message
# to branch names that are more understandable to the casual reader of the git log.

# Option --no-ff instructs git to always record a merge commit, even if
# the branch being merged into can be fast-forwarded. This is often the
# case when you create a short-lived topic branch which tracks master, do
# some changes on the topic branch and then merge the changes into the
# master which remained unchanged while you were doing your work on the
# topic branch. In this case the master branch can be fast-forwarded (that
# is the tip of the master branch can be updated to point to the tip of
# the topic branch) and this is what git does by default. With --no-ff
# option set, git creates a real merge commit which records the fact that
# another branch was merged. I find this easier to understand and read in
# the log.

mergeoptions = --no-commit --no-ff

The OP adds in the comments:

I see some sense in fast-forward for [short-lived] branches, but making it the default action means that git assumes you... often have [short-lived] branches. Reasonable?

Jefromi answers:

I think the lifetime of branches varies greatly from user to user. Among experienced users, though, there's probably a tendency to have far more short-lived branches.

To me, a short-lived branch is one that I create in order to make a certain operation easier (rebasing, likely, or quick patching and testing), and then immediately delete once I'm done.
That means it likely should be absorbed into the topic branch it forked from, and the topic branch will be merged as one branch. No one needs to know what I did internally in order to create the series of commits implementing that given feature.

More generally, I add:

it really depends on your development workflow:

• if it is linear, one branch makes sense.
• If you need to isolate features and work on them for a long period of time and repeatedly merge them, several branches make sense.

See "When should you branch?"

Actually, when you consider the Mercurial branch model, it is at its core one branch per repository (even though you can create anonymous heads, bookmarks and even named branches)
See "Git and Mercurial - Compare and Contrast".

Mercurial, by default, uses anonymous lightweight codelines, which in its terminology are called "heads".
Git uses lightweight named branches, with injective mapping to map names of branches in remote repository to names of remote-tracking branches.
Git "forces" you to name branches (well, with the exception of a single unnamed branch, which is a situation called a "detached HEAD"), but I think this works better with branch-heavy workflows such as topic branch workflow, meaning multiple branches in a single repository paradigm.

Your problem comes from the 32/64 bit version of your JDK/JRE... Your shared lib is searched for a 32 bit version.

Your default JDK is a 32 bit version. Try to install a 64 bit one by default and relaunch your `.sh file.

This question actually is not JSP related, it is HTTP related. you can just do:

window.location = window.location;

import cv2 as cv

im_color = cv.imread("lena.png", cv.IMREAD_COLOR)
im_gray = cv.cvtColor(im_color, cv.COLOR_BGR2GRAY)

At this point you have a color and a gray image. We are dealing with 8-bit, uint8 images here. That means the images can have pixel values in the range of [0, 255] and the values have to be integers.

Let's do a binary thresholding operation. It creates a black and white masked image. The black regions have value 0 and the white regions 255

_, mask = cv.threshold(im_gray, thresh=180, maxval=255, type=cv.THRESH_BINARY)
im_thresh_gray = cv.bitwise_and(im_gray, mask)

The mask can be seen below on the left. The image on it's right is the result of applying bitwise_and operation between the gray image and the mask. What happened is, the spatial locations where the mask had a pixel value zero (black), became pixel value zero in the result image. The locations where the mask had pixel value 255 (white), the resulting image retained it's original gray value.

To apply this mask to our original color image, we need to convert the mask into a 3 channel image as the original color image is a 3 channel image.

mask3 = cv.cvtColor(mask, cv.COLOR_GRAY2BGR)  # 3 channel mask

Then, we can apply this 3 channel mask to our color image using the same bitwise_and function.

im_thresh_color = cv.bitwise_and(im_color, mask3)

mask3 from the code is the image below on the left, and im_thresh_color is on its right.

You can plot the results and see for yourself.

cv.imshow("original image", im_color)
cv.imshow("binary mask", mask)
cv.imshow("3 channel mask", mask3)
cv.imshow("im_thresh_gray", im_thresh_gray)
cv.imshow("im_thresh_color", im_thresh_color)
cv.waitKey(0)

The original image is lenacolor.png that I found here.

I imagine a simple Replace in Files (Ctrl+Shift+H) will just about do the trick; simply replace namespace DemoApp with namespace MyApp. After that, build the solution and look for compile errors for unknown identifiers. Anything that fully qualified DemoApp will need to be changed to MyApp.

With Yglu Structural Templating, your example can be written:

foo: !()
  !? $.propname: 
     type: number 
     default: !? $.default

bar:
  !apply .foo: 
    propname: "some_prop"
    default: "some default"

One thing to watch out for in benchmarks (especially phpbench.com), is even though the numbers are sound, the tests are not. Alot of the tests on phpbench.com are doing things at are trivial and abuse PHP's ability to cache array lookups to skew benchmarks or in the case of iterating over an array doesn't actually test it in real world cases (no one writes empty for loops). I've done my own benchmarks that I've found are fairly reflective of the real world results and they always show the language's native iterating syntax foreach coming out on top (surprise, surprise).

//make a nicely random array
$aHash1 = range( 0, 999999 );
$aHash2 = range( 0, 999999 );
shuffle( $aHash1 );
shuffle( $aHash2 );
$aHash = array_combine( $aHash1, $aHash2 );


$start1 = microtime(true);
foreach($aHash as $key=>$val) $aHash[$key]++;
$end1 = microtime(true);

$start2 = microtime(true);
while(list($key) = each($aHash)) $aHash[$key]++;
$end2 = microtime(true);


$start3 = microtime(true);
$key = array_keys($aHash);
$size = sizeOf($key);
for ($i=0; $i<$size; $i++) $aHash[$key[$i]]++;
$end3 = microtime(true);

$start4 = microtime(true);
foreach($aHash as &$val) $val++;
$end4 = microtime(true);

echo "foreach ".($end1 - $start1)."\n"; //foreach 0.947947025299

//optimize out the loopup.
function noop( $value ) {}

//Create an array of increasing indexes, w/ random values
$bHash = range( 0, 999999 );
shuffle( $bHash );

$bstart1 = microtime(true);
for($i = 0; $i < 1000000; ++$i) noop( $bHash[$i] );
$bend1 = microtime(true);

$bstart2 = microtime(true);
$i = 0; while($i < 1000000) { noop( $bHash[$i] ); ++$i; }
$bend2 = microtime(true);


$bstart3 = microtime(true);
foreach( $bHash as $value ) { noop( $value ); }
$bend3 = microtime(true);

echo "for ".($bend1 - $bstart1)."\n"; //for 0.397135972977
echo "while ".($bend2 - $bstart2)."\n"; //while 0.364789962769

• If you want to be able to run it inside cmd.exe or batch files you need to add the directory the .exe is in to the %path% variable (System or User)
• If you want to be able to run it in the Run dialog (Win+R) or any application that calls ShellExecute, adding your exe to the app paths key is enough (This is less error prone during install/uninstall and also does not clutter up the path variable)

In code:

editText.setEnabled(false);

Or, in XML:

android:editable="false"

Using Django's session framework should cover most scenarios, but Django also now provide direct cookie manipulation methods on the request and response objects (so you don't need a helper function).

Setting a cookie:

def view(request):
  response = HttpResponse('blah')
  response.set_cookie('cookie_name', 'cookie_value')

Retrieving a cookie:

def view(request):
  value = request.COOKIES.get('cookie_name')
  if value is None:
    # Cookie is not set

  # OR

  try:
    value = request.COOKIES['cookie_name']
  except KeyError:
    # Cookie is not set

If making a call to asp.net, this will return the error message title:

I didn't write all of formatErrorMessage myself but i find it very useful.

function formatErrorMessage(jqXHR, exception) {

    if (jqXHR.status === 0) {

    } else if (jqXHR.status == 404) {
        return ('The requested page not found. [404]');
    } else if (jqXHR.status == 500) {
        return ('Internal Server Error [500].');
    } else if (exception === 'parsererror') {
        return ('Requested JSON parse failed.');
    } else if (exception === 'timeout') {
        return ('Time out error.');
    } else if (exception === 'abort') {
        return ('Ajax request aborted.');
    } else {
        return ('Uncaught Error.\n' + jqXHR.responseText);
    }
}


var jqxhr = $.post(addresshere, function() {
  alert("success");
})
.done(function() { alert("second success"); })
.fail(function(xhr, err) { 

    var responseTitle= $(xhr.responseText).filter('title').get(0);
    alert($(responseTitle).text() + "\n" + formatErrorMessage(xhr, err) ); 
})

Following solution will drop specific default constraint of a column from the table

Declare @Const NVARCHAR(256)

SET @Const = (
              SELECT TOP 1 'ALTER TABLE' + YOUR TABLE NAME +' DROP CONSTRAINT '+name
              FROM Sys.default_constraints A
              JOIN sysconstraints B on A.parent_object_id = B.id
              WHERE id = OBJECT_ID('YOUR TABLE NAME')
              AND COL_NAME(id, colid)='COLUMN NAME'
              AND OBJECTPROPERTY(constid,'IsDefaultCnst')=1
            )
 EXEC (@Const)

Here is a solution that does not require functions to get an accurate count for each table:

select table_schema, 
       table_name, 
       (xpath('/row/cnt/text()', xml_count))[1]::text::int as row_count
from (
  select table_name, table_schema, 
         query_to_xml(format('select count(*) as cnt from %I.%I', table_schema, table_name), false, true, '') as xml_count
  from information_schema.tables
  where table_schema = 'public' --<< change here for the schema you want
) t

query_to_xml will run the passed SQL query and return an XML with the result (the row count for that table). The outer xpath() will then extract the count information from that xml and convert it to a number

The derived table is not really necessary, but makes the xpath() a bit easier to understand - otherwise the whole query_to_xml() would need to be passed to the xpath() function.

One possible workaround would be using a "frame-breaker" script as described here

You just need to alter the "if" statement to check for your allowed domains.

   if (self === top) {
       var antiClickjack = document.getElementById("antiClickjack");
       antiClickjack.parentNode.removeChild(antiClickjack);
   } else {
       //your domain check goes here
       if(top.location.host != "allowed.domain1.com" && top.location.host == "allowed.domain2.com")
         top.location = self.location;
   }

This workaround would be safe, I think. because with javascript not enabled you will have no security concern about a malicious website framing your page.

The original order is in fact backwards. Certs should be followed by the issuing cert until the last cert is issued by a known root per IETF's RFC 5246 Section 7.4.2

This is a sequence (chain) of certificates. The sender's certificate MUST come first in the list. Each following certificate MUST directly certify the one preceding it.

See also SSL: error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch for troubleshooting techniques.

But I still don't know why they wrote the spec so that the order matters.

Not really great but a funny hack: You can -- instead of +

{{num_str -- 1 }}

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>_x000D_
<div ng-app>_x000D_
  {{'1'--1}}_x000D_
</div>

This works for me: $('#profile1').attr('onclick')

I believe you can use a case statement in a where clause, here is how I do it:

Select 
ProductID
OrderNo,
OrderType,
OrderLineNo
From Order_Detail
Where ProductID in (
Select Case when (@Varibale1 != '') 
then (Select ProductID from Product P Where .......)
Else (Select ProductID from Product)
End as ProductID
)

This method has worked for me time and again. try it!

In the solutions in previous answers selection is stopped, but the user still thinks you can select text because the cursor still changes. To keep it static, you'll have to set your CSS cursor:

.noselect {_x000D_
    cursor: default;_x000D_
    -webkit-touch-callout: none;_x000D_
    -webkit-user-select: none;_x000D_
    -khtml-user-select: none;_x000D_
    -moz-user-select: none;_x000D_
    -ms-user-select: none;_x000D_
    user-select: none;_x000D_
}

<p>_x000D_
  Selectable text._x000D_
</p>_x000D_
<p class="noselect">_x000D_
  Unselectable text._x000D_
</p>

This will make your text totally flat, like it would be in a desktop application.

Please check your Windows system event log for any errors specifically for the "Event Source: Dhcp". It's very likely a networking error related to DHCP. Address lease time expired or so. It shouldn't be a problem related to the SQL Server or the query itself.

Just search the internet for "The semaphore timeout period has expired" and you'll get plenty of suggestions what might be a solution for your problem. Unfortunately there doesn't seem to be the solution for this problem.

First two columns and 5 rows

 df.select(df.columns[:2]).take(5)

Leave your email.php code the same, but replace this JavaScript code:

 var name = $("#form_name").val();
        var email = $("#form_email").val();
        var text = $("#msg_text").val();
        var dataString = 'name='+ name + '&email=' + email + '&text=' + text;

        $.ajax({
            type: "POST",
            url: "email.php",
            data: dataString,
            success: function(){
            $('.success').fadeIn(1000);
            }
        });

with this:

    $.ajax({
        type: "POST",
        url: "email.php",
        data: $(form).serialize(),
        success: function(){
        $('.success').fadeIn(1000);
        }
    });

So that your form input names match up.

Setting height to 101% is my solution to the problem. You pages will no longer 'flick' when switching between ones that exceed the viewport height and ones that do not.

The struct b line doesn't work because it's a syntax error. If you expand it out to include the type it will work just fine

struct MyObj b = a;  // Runs fine

What C is doing here is essentially a memcpy from the source struct to the destination. This is true for both assignment and return of struct values (and really every other value in C)

... using org.apache.http api. ...

You need to include SOAPAction as a header in the request. As you have httpPost and requestWrapper handles, there are three ways adding the header.

 1. httpPost.addHeader( "SOAPAction", strReferenceToSoapActionValue );
 2. httpPost.setHeader( "SOAPAction", strReferenceToSoapActionValue );
 3. requestWrapper.setHeader( "SOAPAction", strReferenceToSoapActionValue );

Only difference is that addHeader allows multiple values with same header name and setHeader allows unique header names only. setHeader(... over writes first header with the same name.

You can go with any of these on your requirement.

This happened to me and I found a solution, see if this works for you:

Once you have built your project with the hammer icon:

1. select "Run".
2. Run Configurations.
3. Choose "C++ Application".
4. Click on the "New Launch Configuration" icon on the top left of the open window.
5. Select "Browse" under the C/C++ Application.
6. Browse to the folder where you made your project initially.
7. Enter the Debug folder.
8. Click on the binary file with the same name as the project.
9. Select "OK".
10. Click "Apply" to confirm the link you just set.
11. Close that window.

Afterwards you should be able to run the project as much as you'd like.

Hopefully this works for you.

Depending on the libc release it could be needed to set both SO_REUSEADDR and SO_REUSEPORT socket options as explained in socket(7) documentation :

   SO_REUSEPORT (since Linux 3.9)
          Permits multiple AF_INET or AF_INET6 sockets to be bound to an
          identical socket address.  This option must be set on each
          socket (including the first socket) prior to calling bind(2)
          on the socket.  To prevent port hijacking, all of the
          processes binding to the same address must have the same
          effective UID.  This option can be employed with both TCP and
          UDP sockets.

As this socket option appears with kernel 3.9 and raspberry use 3.12.x, it will be needed to set SO_REUSEPORT.

You can set theses two options before calling bind like this :

    int reuse = 1;
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, (const char*)&reuse, sizeof(reuse)) < 0)
        perror("setsockopt(SO_REUSEADDR) failed");

#ifdef SO_REUSEPORT
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEPORT, (const char*)&reuse, sizeof(reuse)) < 0) 
        perror("setsockopt(SO_REUSEPORT) failed");
#endif

Replace

new Timestamp();

with

new java.util.Date()

because there is no default constructor for Timestamp, or you can do it with the method:

new Timestamp(System.currentTimeMillis());

This has to do with the browser's box model. Use something like jQuery or another JavaScript abstraction library to normalize the DOM model.

Should be probably changed to

firstName = firstName.trim().replaceAll("\\.", "");

Serialize both objects, then calculate Hash Code, then compare.

this is pretty basic stuff, all you need to do is to create a base view model and make sure ALL! and i mean ALL! of your views that will ever use that layout will receive views that use that base model!

public class SomeViewModel : ViewModelBase
{
    public bool ImNotEmpty = true;
}

public class EmptyViewModel : ViewModelBase
{
}

public abstract class ViewModelBase
{
}

in the _Layout.cshtml:

@model Models.ViewModelBase
<!DOCTYPE html>
  <html>
  and so on...

in the the Index (for example) method in the home controller:

    public ActionResult Index()
    {
        var model = new SomeViewModel()
        {
        };
        return View(model);
    }

the Index.cshtml:

@model Models.SomeViewModel

@{
  ViewBag.Title = "Title";
  Layout = "~/Views/Shared/_Layout.cshtml";
}

<div class="row">

i disagree that passing a model to the _layout is an error, some user info can be passed and the data can be populate in the controllers inheritance chain so only one implementation is needed.

obviously for more advanced purpose you should consider creating custom static contaxt using injection and include that model namespace in the _Layout.cshtml.

but for basic users this will do the trick

Resolved this issue by navigating to C:\xampp\mysql\bin and double clicking on mysqld.exe and then allow access in the pop up that comes. My server status on workbench changed to running

BufferedReader can't wrap an InputStream directly. It wraps another Reader. In this case you'd want to do something like:

BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"));

tl;dr

Import the root module with importlib.import_module and load the class by its name using getattr function:

# Standard import
import importlib
# Load "module.submodule.MyClass"
MyClass = getattr(importlib.import_module("module.submodule"), "MyClass")
# Instantiate the class (pass arguments to the constructor, if needed)
instance = MyClass()

explanations

You probably don't want to use __import__ to dynamically import a module by name, as it does not allow you to import submodules:

>>> mod = __import__("os.path")
>>> mod.join
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'join'

Here is what the python doc says about __import__:

Note: This is an advanced function that is not needed in everyday Python programming, unlike importlib.import_module().

Instead, use the standard importlib module to dynamically import a module by name. With getattr you can then instantiate a class by its name:

import importlib
my_module = importlib.import_module("module.submodule")
MyClass = getattr(my_module, "MyClass")
instance = MyClass()

You could also write:

import importlib
module_name, class_name = "module.submodule.MyClass".rsplit(".", 1)
MyClass = getattr(importlib.import_module(module_name), class_name)
instance = MyClass()

This code is valid in python = 2.7 (including python 3).

You would need to add a property to your Production class and set it to point back at its parent, this doesn't exist by default.

If you like to write CoffeeScript you could do:

hello = "foo"
my_string = "I pity the #{hello}"

CoffeeScript actually IS javascript, but with a much better syntax.

For an overview of CoffeeScript check this beginner's guide.

This is one of the outright idiocies of CSS - I have yet to understand the reasoning (if someone knows, pls. explain).

100% means 100% of the container height - to which any margins, borders and padding are added. So it is effectively impossible to get a container which fills it's parent and which has a margin, border, or padding.

Note also, setting height is notoriously inconsistent between browsers, too.

Another thing I've learned since I posted this is that the percentage is relative the container's length, that is, it's width, making a percentage even more worthless for height.

Nowadays, the vh and vw viewport units are more useful, but still not especially useful for anything other than the top-level containers.

I needed a very simple solution to hide something after sometime and managed to get this to work:

In angular you can do this:

$timeout(self.hideError,2000);

Here is the function that i call when the timeout has been reached

 self.hideError = function(){
   self.HasError = false;
   self.ErrorMessage = '';
};

So now my dialog/ui can use those properties to hide elements.

Set java.library.path to a directory containing this DLL which Java uses to find native libraries. Specify -D switch on the command line

java -Djava.library.path=C:\Java\native\libs YourProgram

C:\Java\native\libs should contain sqljdbc_auth.dll

Look at this SO post if you are using Eclipse or at this blog if you want to set programatically.

There are 2 types of multidimensional arrays in C#, called Multidimensional and Jagged.

For multidimensional you can by:

string[,] multi = new string[3, 3];

For jagged array you have to write a bit more code:

string[][] jagged = new string[3][];
            for (int i = 0; i < jagged.Length; i++)
            {
                jagged[i] = new string[3];
            }

In short jagged array is both faster and has intuitive syntax. For more information see: this Stackoverflow question

The reason you might not be getting any results is because you might not be having the J2EE environment setup in your Eclipse IDE. Follow these steps to solve the problem.

1. Goto Help -> Install new Software Select relevant dropdown entry {Oxygen - http://download.eclipse.org/releases/<?>} (or Similar option/version) in the "Work with" tab.

2. Search for Web,XML,Java EE and OSGi Enterprise Development Check the boxes corresponding to,Eclipse Java EE Developer Tools JST Server Adapters JST Server Adapters Extensions Click next and accept the license agreement.

To track installations, you could for example use a UUID as an identifier, and simply create a new one the first time an app runs after installation. Here is a sketch of a class named “Installation” with one static method Installation.id(Context context). You could imagine writing more installation-specific data into the INSTALLATION file.

public class Installation {
private static String sID = null;
private static final String INSTALLATION = "INSTALLATION";
public synchronized static String id(Context context) {

    if (sID == null) {  
       File installation = new File(context.getFilesDir(), INSTALLATION);
       try {
           if (!installation.exists())
               writeInstallationFile(installation);
           sID = readInstallationFile(installation);
       } catch (Exception e) {
           throw new RuntimeException(e);
       }
    }
   return sID;
}

private static String readInstallationFile(File installation) throws IOException {
   RandomAccessFile f = new RandomAccessFile(installation, "r");
   byte[] bytes = new byte[(int) f.length()];
   f.readFully(bytes);
   f.close();
   return new String(bytes);
}

private static void writeInstallationFile(File installation) throws IOException {
   FileOutputStream out = new FileOutputStream(installation);
   String id = UUID.randomUUID().toString();
   out.write(id.getBytes());
   out.close();
}

}

In your code:

var obj = {
  myProp: string;
};

You are actually creating a object literal and assigning the variable string to the property myProp. Although very bad practice this would actually be valid TS code (don't use this!):

var string = 'A string';

var obj = {
  property: string
};

However, what you want is that the object literal is typed. This can be achieved in various ways:

Interface:

interface myObj {
    property: string;
}

var obj: myObj = { property: "My string" };

Type alias:

type myObjType = {
    property: string
};

var obj: myObjType = { property: "My string" };

Object type literal:

var obj: { property: string; } = { property: "Mystring" };

You could try with android:background="@android:drawable/list_selector_background" to get the same effect as the "Add alarm" in the default "Alarm Clock" (now Desk Clock).

Found the code that I referred to in my comment above. To test it, do this:

1. In Sheet1 change the cell height and width of say A1 as shown in the snapshot below.
2. Format the cell by right clicking on it to show time format
3. Add two buttons (form controls) on the worksheet and name them as shown in the snapshot
4. Paste this code in a module
5. Right click on the Start Timer button on the sheet and click on Assign Macros. Select StartTimer macro.
6. Right click on the End Timer button on the sheet and click on Assign Macros. Select EndTimer macro.

Now click on Start Timer button and you will see the time getting updated in cell A1. To stop time updates, Click on End Timer button.

Code (TRIED AND TESTED)

SNAPSHOT

Try the following:

<script> 
 //Functions to open database and to create, insert data into tables

 getSelectedRow = function(val)
    {
        db.transaction(function(transaction) {
              transaction.executeSql('SELECT * FROM Employ where number = ?;',[parseInt(val)], selectedRowValues, errorHandler);

        });
    };
    selectedRowValues = function(transaction,results)
    {
         for(var i = 0; i < results.rows.length; i++)
         {
             var row = results.rows.item(i);
             alert(row['number']);
             alert(row['name']);                 
         }
    };
</script>

You don't have access to javascript variable names in SQL, you must pass the values to the Database.

If using a BeansWrapper with an exposure level of Expose.SAFE or Expose.ALL, then the standard Java approach of iterating the entry set can be employed:

For example, the following will work in Freemarker (since at least version 2.3.19):

<#list map.entrySet() as entry>  
  <input type="hidden" name="${entry.key}" value="${entry.value}" />
</#list>

In Struts2, for instance, an extension of the BeanWrapper is used with the exposure level defaulted to allow this manner of iteration.

If your array has static storage allocation, it is default initialized to zero. However, if the array has automatic storage allocation, then you can simply initialize all its elements to zero using an array initializer list which contains a zero.

// function scope
// this initializes all elements to 0
int arr[4] = {0};
// equivalent to
int arr[4] = {0, 0, 0, 0};

// file scope
int arr[4];
// equivalent to
int arr[4] = {0};

Please note that there is no standard way to initialize the elements of an array to a value other than zero using an initializer list which contains a single element (the value). You must explicitly initialize all elements of the array using the initializer list.

// initialize all elements to 4
int arr[4] = {4, 4, 4, 4};
// equivalent to
int arr[] = {4, 4, 4, 4};

Line breaks are considered as content to elements in FF.

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

Ex:

$("div:empty").text("Empty").css('background', '#ff0000');

In IE both divs are considered empty, in FF an Chrome only the last one is empty.

You can use the solution provided by @qwertymk

if(!/[\S]/.test($('#element').html())) { // for one element
    alert('empty');
}

or

$('.elements').each(function(){  // for many elements
    if(!/[\S]/.test($(this).html())) { 
        // is empty
    }
})

You can simply do it like this with an object literal:

function makeGamePlayer(name,totalScore,gamesPlayed) {
    return {
        name: name,
        totalscore: totalScore,
        gamesPlayed: gamesPlayed
    };
}

First off you need to download and install ODP from this site http://www.oracle.com/technetwork/topics/dotnet/index-085163.html

After installation add a reference of the assembly Oracle.DataAccess.dll.

Your are good to go after this.

using System; 
using Oracle.DataAccess.Client; 

class OraTest
{ 
    OracleConnection con; 
    void Connect() 
    { 
        con = new OracleConnection(); 
        con.ConnectionString = "User Id=<username>;Password=<password>;Data Source=<datasource>"; 
        con.Open(); 
        Console.WriteLine("Connected to Oracle" + con.ServerVersion); 
    }

    void Close() 
    {
        con.Close(); 
        con.Dispose(); 
    } 

    static void Main() 
    { 
        OraTest ot= new OraTest(); 
        ot.Connect(); 
        ot.Close(); 
    } 
}

You can also use like below code.

<button style="position: absolute; right: 0;">Button</button>

I would like to draw attention to the fact that a simple <meta property="og:image" content="image.png" />, as suggested somewhere above, does not work for me (this in fact had me in a loop for weeks now). What works is either an absolute URL:
<meta property="og:image" content="https://domainname.com/image.png" />

or starting out with a slash (if the image is in the root directory):
<meta property="og:image" content="/image.png" />

(I would have added this as a comment, but I'm not allowed to yet. Moderators feel free to move this if more appropriate.)

I thought this would work, based on this source.

SELECT

However, Justin Cave is right. This query gives better results:

J(2)EE, strictly speaking, is a set of APIs (as the current top answer has it) which enable a programmer to build distributed, transactional systems. The idea was to abstract away the complicated distributed, transactional bits (which would be implemented by a Container such as WebSphere or Weblogic), leaving the programmer to develop business logic free from worries about storage mechanisms and synchronization.

In reality, it was a cobbled-together, design-by-committee mish-mash, which was pushed pretty much for the benefit of vendors like IBM, Oracle and BEA so they could sell ridicously over-complicated, over-engineered, over-useless products. Which didn't have the most basic features (such as scheduling)!

J2EE was a marketing construct.

Actually, there is a gem called Jsonable, https://github.com/treeder/jsonable. It's pretty sweet.

Only a teacher would ask you to do something silly like this. You could provide an expected answer. Or a unique solution, while the rest of the class will be (yawn) the same...

from operator import lt, gt
def ultimate (l,op,c=1,u=0):
    try:
        if op(l[c],l[u]): 
            u = c
        c += 1
        return ultimate(l,op,c,u)
    except IndexError:
        return l[u]
def minimum (l):
    return ultimate(l,lt)
def maximum (l):
    return ultimate(l,gt)

The solution is simple. Use this to set yourself apart from obvious choices.

I ended up with a custom extension method. Its worth noting, when trying to place HTML inside of an Anchor object, the link text can be either to the left, or to the right of the inner HTML. For this reason, I opted to provide parameters for left and right inner HTML - the link text is in the middle. Both left and right inner HTML are optional.

Extension Method ActionLinkInnerHtml:

    public static MvcHtmlString ActionLinkInnerHtml(this HtmlHelper helper, string linkText, string actionName, string controllerName, RouteValueDictionary routeValues = null, IDictionary<string, object> htmlAttributes = null, string leftInnerHtml = null, string rightInnerHtml = null)
    {
        // CONSTRUCT THE URL
        var urlHelper = new UrlHelper(helper.ViewContext.RequestContext);
        var url = urlHelper.Action(actionName: actionName, controllerName: controllerName, routeValues: routeValues);

        // CREATE AN ANCHOR TAG BUILDER
        var builder = new TagBuilder("a");
        builder.InnerHtml = string.Format("{0}{1}{2}", leftInnerHtml, linkText, rightInnerHtml);
        builder.MergeAttribute(key: "href", value: url);

        // ADD HTML ATTRIBUTES
        builder.MergeAttributes(htmlAttributes, replaceExisting: true);

        // BUILD THE STRING AND RETURN IT
        var mvcHtmlString = MvcHtmlString.Create(builder.ToString());
        return mvcHtmlString;
    }

Example of Usage:

Here is an example of usage. For this example I only wanted the inner html on the right side of the link text...

@Html.ActionLinkInnerHtml(
    linkText: "Hello World"
        , actionName: "SomethingOtherThanIndex"
        , controllerName: "SomethingOtherThanHome"
        , rightInnerHtml: "<span class=\"caret\" />"
        )

Results:

this results in the following HTML...

<a href="/SomethingOtherThanHome/SomethingOtherThanIndex">Hello World<span class="caret" /></a>

Wouldn't a simple background image for the textarea suffice?

Whats the value for the SqlException.ErrorCode property? Can you work with that?

When having timeouts, it may be worth checking the code for -2146232060.

I would set this up as a static const in your data code.

I had the same issue using Windows, got if fixed by opening it in Notepad++ and changing the encoding from "UCS-2 LE BOM" to "UTF-8".

In my case the sha command was missing from my linux distro; steps were

• added the packages for sha512 (on my distro sudo apt install hashalot)
• npm cache verify
• rm -rf node_modules
• npm install

Plenty of resources for doing it. Easy to implement.

I think oracle is smart enough to convert the less efficient one (whichever that is) into the other. So I think the answer should rather depend on the readability of each (where I think that IN clearly wins)


 is the HTML representation in hex of a line feed character. It represents a new line on Unix and Unix-like (for example) operating systems.

You can find a list of such characters at (for example) http://la.remifa.so/unicode/latin1.html

You can also try using a C#/Perl/Java script get the utilization data using WMI Commands, and below is the steps for it.

We need to execute 2 WMI Select Queries and apply CPU% utilization formula

1. To retrieve the total number of logical process

select NumberOfLogicalProcessors from Win32_ComputerSystem

2. To retrieve the values of PercentProcessorTime, TimeStamp_Sys100NS ( CPU utilization formula has be applied get the actual utilization percentage)and WorkingSetPrivate ( RAM ) minimum of 2 times with a sleep interval of 1 second

select * from Win32_PerfRawData_PerfProc_Process where IDProcess=1234

3. Apply CPU% utilization formula

CPU%= ((p2-p1)/(t2-t1)*100)/NumberOfLogicalProcessors

p2 indicated PercentProcessorTime retrieved for the second time, and p1 indicateds the PercentProcessorTime retrieved for the first time, t2 and t1 is for TimeStamp_Sys100NS.

A sample Perl code for this can be found in the link http://www.craftedforeveryone.com/cpu-and-ram-utilization-of-an-application-using-perl-via-wmi/

This logic applies for all programming language which supports WMI queries

Java converts Integer to int and back automatically (unless you are still with Java 1.4).

I found that these instructions were not enough. I also had to search through the code files for models, controllers, and views as well as the AppStart files to change the namespace.

Since I was copying my project not just renaming it, I also had to go into the applicationhost.config for IIS express and recreate the bindings using different port numbers and change the physical directory as well.

If for matching identical images - code for L2 distance

// Compare two images by getting the L2 error (square-root of sum of squared error).
double getSimilarity( const Mat A, const Mat B ) {
if ( A.rows > 0 && A.rows == B.rows && A.cols > 0 && A.cols == B.cols ) {
    // Calculate the L2 relative error between images.
    double errorL2 = norm( A, B, CV_L2 );
    // Convert to a reasonable scale, since L2 error is summed across all pixels of the image.
    double similarity = errorL2 / (double)( A.rows * A.cols );
    return similarity;
}
else {
    //Images have a different size
    return 100000000.0;  // Return a bad value
}

Fast. But not robust to changes in lighting/viewpoint etc. Source

You could use POSIX [[:blank:]] to match a horizontal white-space character.

sed 's/[[:blank:]]\+/\n/g' file

or you may use [[:space:]] instead of [[:blank:]] also.

Example:

$ echo 'this  is a sentence' | sed 's/[[:blank:]]\+/\n/g'
this
is
a
sentence

In case you want to use the class and pseudo-class:

.simple-control is your css class

:disabled is pseudo class

select.simple-control:disabled{
         /*For FireFox*/
        -webkit-appearance: none;
        /*For Chrome*/
        -moz-appearance: none;
}

/*For IE10+*/
select:disabled.simple-control::-ms-expand {
        display: none;
}

Try with Shadow( Like border ) + Border

border-bottom: 5px solid #fff;
box-shadow: 0 5px 0 #ffbf0e;

simplest way to center your div element is to use this class with following properties.

.light {
    margin: auto;
    width: 50%;
    border: 3px solid green;
    padding: 10px;
}

A big thank you to @Musa and here is a neat function that converts the data to a base64 string. This may come handy to you when handling a binary file (pdf, png, jpeg, docx, ...) file in a WebView that gets the binary file but you need to transfer the file's data safely into your app.

// runs a get/post on url with post variables, where:
// url ... your url
// post ... {'key1':'value1', 'key2':'value2', ...}
//          set to null if you need a GET instead of POST req
// done ... function(t) called when request returns
function getFile(url, post, done)
{
   var postEnc, method;
   if (post == null)
   {
      postEnc = '';
      method = 'GET';
   }
   else
   {
      method = 'POST';
      postEnc = new FormData();
      for(var i in post)
         postEnc.append(i, post[i]);
   }
   var xhr = new XMLHttpRequest();
   xhr.onreadystatechange = function() {
      if (this.readyState == 4 && this.status == 200)
      {
         var res = this.response;
         var reader = new window.FileReader();
         reader.readAsDataURL(res); 
         reader.onloadend = function() { done(reader.result.split('base64,')[1]); }
      }
   }
   xhr.open(method, url);
   xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
   xhr.send('fname=Henry&lname=Ford');
   xhr.responseType = 'blob';
   xhr.send(postEnc);
}

Update (6/15/16)

I have created much more thorough benchmarks. First of all, as @ChaimG pointed out, early binding makes a big difference (I originally used @eksortso's code above verbatim which uses late binding). Secondly, my original benchmarks only included the time to create the unique object, however, it did not test the efficiency of using the object. My point in doing this is, it doesn't really matter if I can create an object really fast if the object I create is clunky and slows me down moving forward.

Old Remark: It turns out, that looping over a collection object is highly inefficient

It turns out that looping over a collection can be quite efficient if you know how to do it (I didn't). As @ChaimG (yet again), pointed out in the comments, using a For Each construct is ridiculously superior to simply using a For loop. To give you an idea, before changing the loop construct, the time for Collection2 for the Test Case Size = 10^6 was over 1400s (i.e. ~23 minutes). It is now a meager 0.195s (over 7000x faster).

For the Collection method there are two times. The first (my original benchmark Collection1) show the time to create the unique object. The second part (Collection2) shows the time to loop over the object (which is very natural) to create a returnable array as the other functions do.

In the chart below, a yellow background indicates that it was the fastest for that test case, and red indicates the slowest ("Not Tested" algorithms are excluded). The total time for the Collection method is the sum of Collection1 and Collection2. Turquoise indicates that is was the fastest regardless of original order.

Below is the original algorithm I created (I have modified it slightly e.g. I no longer instantiate my own data type). It returns the unique values of an array with the original order in a very respectable time and it can be modified to take on any data type. Outside of the IndexMethod, it is the fastest algorithm for very large arrays.

Here are the main ideas behind this algorithm:

1. Index the array
2. Sort by values
3. Place identical values at the end of the array and subsequently "chop" them off.
4. Finally, sort by index.

Below is an example:

Let myArray = (86, 100, 33, 19, 33, 703, 19, 100, 703, 19)

    1.  (86, 100, 33, 19, 33, 703, 19, 100, 703, 19)
        (1 ,   2,  3,  4,  5,   6,  7,   8,   9, 10)   <<-- Indexing

    2.  (19, 19, 19, 33, 33, 86, 100, 100, 703, 703)   <<-- sort by values     
        (4,   7, 10,  3,  5,  1,   2,   8,   6,   9)

    3.  (19, 33,  86, 100, 703)   <<-- remove duplicates    
        (4,   3,   1,   2,   6)

    4.  (86, 100,  33, 19, 703)   
        ( 1,   2,   3,  4,   6)   <<-- sort by index

Here is the code:

Function SortingUniqueTest(ByRef myArray() As Long, bOrigIndex As Boolean) As Variant
    Dim MyUniqueArr() As Long, i As Long, intInd As Integer
    Dim StrtTime As Double, Endtime As Double, HighB As Long, LowB As Long

    LowB = LBound(myArray): HighB = UBound(myArray)

    ReDim MyUniqueArr(1 To 2, LowB To HighB)
    intInd = 1 - LowB  'Guarantees the indices span 1 to Lim

    For i = LowB To HighB
        MyUniqueArr(1, i) = myArray(i)
        MyUniqueArr(2, i) = i + intInd
    Next i

    Call UniqueArray2D(MyUniqueArr)
    If bOrigIndex Then QSLong2D MyUniqueArr, 2, LBound(MyUniqueArr, 2), UBound(MyUniqueArr, 2), 2

    SortingUniqueTest = MyUniqueArr()
End Function

Public Sub UniqueArray2D(ByRef myArray() As Long)
    Dim i As Long, j As Long, Count As Long, Count1 As Long, DuplicateArr() As Long

    LowB = LBound(myArray, 2): Count = LowB: i = LowB: HighB = UBound(myArray, 2)

    Do While i < HighB
        j = i + 1
        If myArray(1, i) = myArray(1, j) Then
            Do While myArray(1, i) = myArray(1, j)
                ReDim Preserve DuplicateArr(1 To Count)
                DuplicateArr(Count) = j
                Count = Count + 1
                j = j + 1
                If j > HighB Then Exit Do
            Loop

            QSLong2D myArray, 2, i, j - 1, 2
        End If
        i = j
    Loop

    Count1 = HighB

    If Count > 1 Then
        For i = UBound(DuplicateArr) To LBound(DuplicateArr) Step -1

Below is a special algorithm that is blazing fast if your data contains integers. It makes use of indexing and the Boolean data type.

Here is the benchmark function that compares all of the functions. You should note that the last two cases are handled a little bit different because of memory issues. Also note, that I didn't test the Collection method for the Test Case Size = 10,000,000. For some reason, it was returning incorrect results and behaving unusual (I'm guessing the collection object has a limit on how many things you can put in it.

Summary
From the table of results, we can see that the Dictionary method works really well for cases less than about 500,000, however, after that, the IndexMethod really starts to dominate. You will notice that when order doesn't matter and your data is made up of positive integers, there is no comparison to the IndexMethod algorithm (it returns the unique values from an array containing 10 million elements in less than 1 sec!!! Incredible!). Below I have a breakdown of which algorithm is preferred in various cases.

Case 1
Your Data contains integers (i.e. whole numbers, both positive and negative): IndexMethod

Case 2
Your Data contains non-integers (i.e. variant, double, string, etc.) with less than 200000 elements: Dictionary Method

Case 3
Your Data contains non-integers (i.e. variant, double, string, etc.) with more than 200000 elements: Collection Method

If you had to choose one algorithm, in my opinion, the Collection method is still the best as it only requires a few lines of code, it's super general, and it's fast enough.

It is very friendly framework for Notification Area Application... it is enough to add NotificationIcon to base form and change auto-generated code to code below:

public partial class Form1 : Form
{
    private bool hidden = false;

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        this.ShowInTaskbar = false;
        //this.WindowState = FormWindowState.Minimized;
        this.Hide();
        hidden = true;
    }

    private void notifyIcon1_Click(object sender, EventArgs e)
    {
        if (hidden) // this.WindowState == FormWindowState.Minimized)
        {
            // this.WindowState = FormWindowState.Normal;
            this.Show();
            hidden = false;
        }
        else
        {
            // this.WindowState = FormWindowState.Minimized;
            this.Hide();
            hidden = true;
        }
    }
}

For me, ensuring that I had:

#include <iostream>  
#include<string>  
using namespace std;

in my file made something like to_string(12345) work.

I hope this isn't leading too far away from the posted question, but setting the default editor and then using

git commit -e

might be much more comfortable.

A memory heap is a location in memory where memory may be allocated at random access.
Unlike the stack where memory is allocated and released in a very defined order, individual data elements allocated on the heap are typically released in ways which is asynchronous from one another. Any such data element is freed when the program explicitly releases the corresponding pointer, and this may result in a fragmented heap. In opposition only data at the top (or the bottom, depending on the way the stack works) may be released, resulting in data element being freed in the reverse order they were allocated.

Programmatically, you could use:

textView.setTextAppearance(android.R.style.TextAppearance_Large);

The ProGit book has a very good explanation:

Tracking Branches

Checking out a local branch from a remote branch automatically creates what is called a tracking branch. Tracking branches are local branches that have a direct relationship to a remote branch. If you’re on a tracking branch and type git push, Git automatically knows which server and branch to push to. Also, running git pull while on one of these branches fetches all the remote references and then automatically merges in the corresponding remote branch.

When you clone a repository, it generally automatically creates a master branch that tracks origin/master. That’s why git push and git pull work out of the box with no other arguments. However, you can set up other tracking branches if you wish — ones that don’t track branches on origin and don’t track the master branch. The simple case is the example you just saw, running git checkout -b [branch] [remotename]/[branch]. If you have Git version 1.6.2 or later, you can also use the --track shorthand:

$ git checkout --track origin/serverfix
Branch serverfix set up to track remote branch refs/remotes/origin/serverfix.
Switched to a new branch "serverfix"

To set up a local branch with a different name than the remote branch, you can easily use the first version with a different local branch name:

$ git checkout -b sf origin/serverfix
Branch sf set up to track remote branch refs/remotes/origin/serverfix.
Switched to a new branch "sf"

Now, your local branch sf will automatically push to and pull from origin/serverfix.

BONUS: extra git status info

With a tracking branch, git status will tell you whether how far behind your tracking branch you are - useful to remind you that you haven't pushed your changes yet! It looks like this:

$ git status
On branch master
Your branch is ahead of 'origin/master' by 1 commit.
  (use "git push" to publish your local commits)

or

$ git status
On branch dev
Your branch and 'origin/dev' have diverged,
and have 3 and 1 different commits each, respectively.
  (use "git pull" to merge the remote branch into yours)

If you changed my.ini and restarted mysql and you still get this error please check your file path and replace "\" to "/". I solved my proplem after replacing.

Give an ID to uniquely identify the button, lets say myBtn

// when DOM is ready
$(document).ready(function () {

     // Attach Button click event listener 
    $("#myBtn").click(function(){

         // show Modal
         $('#myModal').modal('show');
    });
});

JSFIDDLE

I found at least three ways of doing this:

1. Add public getters on your entity that you try to serialize;
2. Add an annotation at the top of the entity, if you don't want public getters. This will change the default for Jackson from Visbility=DEFAULT to @JsonAutoDetect(fieldVisibility = JsonAutoDetect.Visibility.ANY) where any access modifiers are accepted;
3. Change your ObjectMapper globally by setting objectMapperInstance.setVisibility(JsonMethod.FIELD, Visibility.ANY);. This should be avoided if you don't need this functionality globally.

Choose based on your needs.

I made a jsben.ch for you http://jsben.ch/#/aWxtF ...seems that indexOf is a bit faster.

Two other alternatives:

3. a combination of NULLIF and NVL2. You can only use this if emp_id is NOT NULL, which it is in your case:

   select nvl2(nullif(emp_id,1),'False','True') from employee;
   

4. simple CASE expression (Mt. Schneiders used a so-called searched CASE expression)

   select case emp_id when 1 then 'True' else 'False' end from employee;
   

You could search for:

<li><a href="#">[^\n]+

And replace with:

$0</a>

Where $0 is the whole match. The exact semantics will depend on the language are you using though.

WARNING: You should avoid parsing HTML with regex. Here's why.

For me the solution was to add the following line to the layout:

<LinearLayout
    xmlns:tools="http://schemas.android.com/tools"
    ...
    >

And \n shows up as a new line in the visual editor. Hope it helps!

The simple solution is to just remap coordinates from the original to the final image, copying pixels from one coordinate space to the other, rounding off as necessary -- which may result in some pixels being copied several times adjacent to each other, and other pixels being skipped, depending on whether you're stretching or shrinking (or both) in either dimension. Make sure your copying iterates through the destination space, so all pixels are covered there even if they're painted more than once, rather than thru the source which may skip pixels in the output.

The better solution involves calculating the corresponding source coordinate without rounding, and then using its fractional position between pixels to compute an appropriate average of the (typically) four pixels surrounding that location. This is essentially a filtering operation, so you lose some resolution -- but the result looks a LOT better to the human eye; it does a much better job of retaining small details and avoids creating straight-line artifacts which humans find objectionable.

Note that the same basic approach can be used to remap flat images onto any other shape, including 3D surface mapping.

This is a rewrite of the great post by @Kay, which throws IOException and provides an early exit:

/**
 * Gets image dimensions for given file 
 * @param imgFile image file
 * @return dimensions of image
 * @throws IOException if the file is not a known image
 */
public static Dimension getImageDimension(File imgFile) throws IOException {
  int pos = imgFile.getName().lastIndexOf(".");
  if (pos == -1)
    throw new IOException("No extension for file: " + imgFile.getAbsolutePath());
  String suffix = imgFile.getName().substring(pos + 1);
  Iterator<ImageReader> iter = ImageIO.getImageReadersBySuffix(suffix);
  while(iter.hasNext()) {
    ImageReader reader = iter.next();
    try {
      ImageInputStream stream = new FileImageInputStream(imgFile);
      reader.setInput(stream);
      int width = reader.getWidth(reader.getMinIndex());
      int height = reader.getHeight(reader.getMinIndex());
      return new Dimension(width, height);
    } catch (IOException e) {
      log.warn("Error reading: " + imgFile.getAbsolutePath(), e);
    } finally {
      reader.dispose();
    }
  }

  throw new IOException("Not a known image file: " + imgFile.getAbsolutePath());
}

I guess my rep is not high enough for my input to be considered worthy as a reply.

Make sure that your package is installed in your $GOPATH directory or already inside your workspace/package.

For example: if your $GOPATH = "c:\go", make sure that the package inside C:\Go\src\pkgName

It's simple, use:

val str: String = "%.2f".format(3.14159)

You have to dispatch after the async request ends.

This would work:

export function bindComments(postId) {
    return function(dispatch) {
        return API.fetchComments(postId).then(comments => {
            // dispatch
            dispatch({
                type: BIND_COMMENTS,
                comments,
                postId
            });
        });
    };
}

Because it appends an element to a list? Push is usually used when referring to stacks.

Make sure Tomcat is not currently running and the PID file is removed. Them you should start Tomcat successfully.

If you start fresh then:

1. Create setenv.sh file in <CATALINA_HOME>/bin.
2. In it I set CATALINA_PID=/tmp/tomcat.pid (or other directory of your choice) so you have more control over the Tomcat process.

Then to start Tomcat find catalina.sh in <CATALINA_HOME>/bin and execute:

./catalina.sh start

and to stop it run:

./catalina.sh stop 10 -force

From catalina.sh script's doc:

./catalina.sh

Usage: catalina.sh ( commands ... )
commands:

start             Start Catalina in a separate window
stop              Stop Catalina, waiting up to 5 seconds for the process to end
stop n            Stop Catalina, waiting up to n seconds for the process to end
stop -force       Stop Catalina, wait up to 5 seconds and then use kill -KILL if still running
stop n -force     Stop Catalina, wait up to n seconds and then use kill -KILL if still running

Note: If you want to use -force flag then setting CATALINA_PID is mandatory.

if you have the property "MyProperty" on your data-class, then you bind the IsChecked like this.... (the converter is optional, but sometimes you need that)

<Window.Resources>
<local:MyBoolConverter x:Key="MyBoolConverterKey"/>
</Window.Resources>
<checkbox IsChecked="{Binding Path=MyProperty, Converter={StaticResource MyBoolConverterKey}}"/>

This is expected. Refer to Javadocs for split.

Splits this string around matches of the given regular expression.

This method works as if by invoking the two-argument split(java.lang.String,int) method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.

If you want to keep the multi dimensional array, one should nest the array brackets. see example below where one is added to every element.

>>> a = [[1, 2], [3, 4]]

>>> [[col +1 for col in row] for row in a]
[[2, 3], [4, 5]]

>>> [col +1 for row in a for col in row]
[2, 3, 4, 5]

That will only work if register_globals is on, and it should never be on (unless of course you are defining that variable somewhere else).

Try setting the form's action attribute to ?...

<form method="post" action="?">
   ...
</form>

You can also set it to be blank (""), but older WebKit versions had a bug.

Most likely both tables have a column with the same name. Alias each table, and call each column with the table alias.

Use Conda instead of pip. It works perfectly

conda install PyAudio

Just use GETDATE() or GETUTCDATE() (if you want to get the "universal" UTC time, instead of your local server's time-zone related time).

INSERT INTO [Business]

           ,[LastUpdatedBy])
     VALUES
           (0, 'Joe', 'Thomas', 
           GETDATE(),  <LastUpdatedBy, nvarchar(50),>)

In my case, it was neither systemd nor a cron job, but it was snap. So I had to run:

sudo snap stop docker
sudo snap remove docker

... and the last command actually never ended, I don't know why: this snap thing is really a pain. So I also ran:

sudo apt purge snap

:-)

You want getActivity() inside your class. It's better to use

yourclassname.this.getActivity()

Try this. It's helpful for you.

If you need to order your code into namespaces, just use the keyword namespace:

file1.php

namespace foo\bar;

In file2.php

$obj = new \foo\bar\myObj();

You can also use use. If in file2 you put

use foo\bar as mypath;

you need to use mypath instead of bar anywhere in the file:

$obj  = new mypath\myObj();

Using use foo\bar; is equal to use foo\bar as bar;.

This is one of the dumb mistakes I've done. I spent a lot of time trying to debug this problem and tried all the responses posted above, but in the end, it was one of my many dumb mistakes.

I was using org.apache.logging.log4j.Logger (:fml:) whereas I should have used org.apache.log4j.Logger. Using this correct logger saved my evening.

My Answer might be coming late, but I think it can help newbie. You shall not see logs executed unless the changes are made as below.

2 Files have to be changes when you implement Log4net.

1. Add Reference of log4net.dll in the project.
2. app.config
3. Class file where you will implement Logs.

Inside [app.config] :

First, under 'configSections', you need to add below piece of code;

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

Then, under 'configuration' block, you need to write below piece of code.(This piece of code is customised as per my need , but it works like charm.)

<log4net debug="true">
    <logger name="log">
      <level value="All"></level>
      <appender-ref ref="RollingLogFileAppender" />
    </logger>

    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="log.txt" />
      <appendToFile value="true" />
      <rollingStyle value="Composite" />
      <maxSizeRollBackups value="1" />
      <maximumFileSize value="1MB" />
      <staticLogFileName value="true" />

      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date %C.%M [%line] %-5level - %message %newline %exception %newline" />
      </layout>
    </appender>
</log4net>

Inside Calling Class :

Inside the class where you are going to use this log4net, you need to declare below piece of code.

 ILog log = LogManager.GetLogger("log");

Now, you are ready call log wherever you want in that same class. Below is one of the method you can call while doing operations.

log.Error("message");

Use the BigInteger class that is a part of the Java library.

http://java.sun.com/j2se/1.5.0/docs/api/java/math/BigInteger.html

Set the DIV's z-index to one larger than the other DIVs. You'll also need to make sure the DIV has a position other than static set on it, too.

CSS:

#someDiv {
    z-index:9; 
}

"void value not ignored as it ought to be" this error occurs when function like srand(time(NULL)) does not return something and you are treating it as it is returning something. As in case of pop() function in queue ,if you will store the popped element in a variable you will get the same error because it does not return anything.

Reportlab. There is an open source version, and a paid version which adds the Report Markup Language (an alternative method of defining your document).

This should be pretty efficient, and easier than getting the whole TPL Dataflow working:

var customers = await ids.SelectAsync(async i =>
{
    ICustomerRepo repo = new CustomerRepo();
    return await repo.GetCustomer(i);
});

...

public static async Task<IList<TResult>> SelectAsync<TSource, TResult>(this IEnumerable<TSource> source, Func<TSource, Task<TResult>> selector, int maxDegreesOfParallelism = 4)
{
    var results = new List<TResult>();

    var activeTasks = new HashSet<Task<TResult>>();
    foreach (var item in source)
    {
        activeTasks.Add(selector(item));
        if (activeTasks.Count >= maxDegreesOfParallelism)
        {
            var completed = await Task.WhenAny(activeTasks);
            activeTasks.Remove(completed);
            results.Add(completed.Result);
        }
    }

    results.AddRange(await Task.WhenAll(activeTasks));
    return results;
}

Subset is a very slow function , and I personally find it useless.

I assume you have a data.frame, array, matrix called Mat with A, B, C as column names; then all you need to do is:

• In the case of one condition on one column, lets say column A

  Mat[which(Mat[,'A'] == 10), ]
  

In the case of multiple conditions on different column, you can create a dummy variable. Suppose the conditions are A = 10, B = 5, and C > 2, then we have:

    aux = which(Mat[,'A'] == 10)
    aux = aux[which(Mat[aux,'B'] == 5)]
    aux = aux[which(Mat[aux,'C'] > 2)]
    Mat[aux, ]

By testing the speed advantage with system.time, the which method is 10x faster than the subset method.

To do what most people would want, create a placeholder that isn't an actual line breaking character. Then you can actually combine the approaches for:

REPLACE(REPLACE(REPLACE(MyField, CHAR(13) + CHAR(10), 'something else'), CHAR(13), 'something else'), CHAR(10), 'something else')

This way you replace only once. The approach of:

REPLACE(REPLACE(MyField, CHAR(13), ''), CHAR(10), '')

Works great if you just want to get rid of the CRLF characters, but if you want a placeholder, such as

<br/>

or something, then the first approach is a little more accurate.

My understanding is that interfaces are not that necessary in dynamic languages like Python. In Java (or C++ with its abstract base class) interfaces are means for ensuring that e.g. you're passing the right parameter, able to perform set of tasks.

E.g. if you have observer and observable, observable is interested in subscribing objects that supports IObserver interface, which in turn has notify action. This is checked at compile time.

In Python, there is no such thing as compile time and method lookups are performed at runtime. Moreover, one can override lookup with __getattr__() or __getattribute__() magic methods. In other words, you can pass, as observer, any object that can return callable on accessing notify attribute.

This leads me to the conclusion, that interfaces in Python do exist - it's just their enforcement is postponed to the moment in which they are actually used

PowerShell currently doesn't didn't have a native Inline If (or ternary If) but you could consider to use the custom cmdlet:

IIf <condition> <condition-is-true> <condition-is-false>

See: PowerShell inline If (IIf)

Here is a working css, tested under Firefox / IE7 / Safari / Chrome / Opera.

* {margin:0px;padding:0px;overflow:hidden}
div {position:absolute}
div#header {top:0px;left:0px;right:0px;height:60px}
div#wrapper {top:60px;left:0px;right:0px;bottom:0px;}
div#left {top:0px;bottom:0px;left:0px;width:50%;overflow-y:auto}
div#right {top:0px;bottom:0px;right:0px;width:50%;overflow-y:auto}

"overflow-y" is not w3c-approved, but every major browser supports it. Your two divs #left and #right will display a vertical scrollbar if their content is too high.

For this to work under IE7, you have to trigger the standards-compliant mode by adding a DOCTYPE :

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"_x000D_
            "http://www.w3.org/TR/html4/strict.dtd">_x000D_

I know this questions has been answered, however the reason this is happening to you, was probably because you did not add your username to the docker group.

Here are the steps to do it:

Add the docker group if it doesn't already exist:

sudo groupadd docker

Add the connected user ${USER} to the docker group. Change the user name to match your preferred user:

sudo gpasswd -a ${USER} docker

Restart the Docker daemon:

sudo service docker restart

If you are on Ubuntu 14.04-15.10* use docker.io instead:

sudo service docker.io restart

(If you are on Ubuntu 16.04 the service is named "docker" simply)

Either do a newgrp docker or log out/in to activate the changes to groups.

There is a very nice PHP library for detecting mobile clients here: http://mobiledetect.net

Using that it's quite easy to only display content for a mobile:

include 'Mobile_Detect.php';
$detect = new Mobile_Detect();

// Check for any mobile device.
if ($detect->isMobile()){
   // mobile content
}
else {
   // other content for desktops
}

If your return type is an array then return an empty array otherwise return null.

Here is a nice tutorial, it is what you need. (Source: coursesweb.net/php-mysql)

Register and show online users and visitors

Count Online users and visitors using a MySQL table

In this tutorial you can learn how to register, to count, and display in your webpage the number of online users and visitors. The principle is this: each user / visitor is registered in a text file or database. Every time a page of the website is accessed, the php script deletes all records older than a certain time (eg 2 minutes), adds the current user / visitor and takes the number of records left to display.

You can store the online users and visitors in a file on the server, or in a MySQL table. In this case, I think that using a text file to add and read the records is faster than storing them into a MySQL table, which requires more requests.

First it's presented the method with recording in a text file on the server, than the method with MySQL table.

To download the files with the scripts presented in this tutorial, click -> Count Online Users and Visitors.

• Both scripts can be included in ".php" files (with include()), or in ".html" files (with <script>), as you can see in the examples presented at the bottom of this page; but the server must run PHP.

Storing online users and visitors in a text file

To add records in a file on the server with PHP you must set CHMOD 0766 (or CHMOD 0777) permissions to that file, so the PHP can write data in it.

1. Create a text file on your server (for example, named userson.txt) and give it CHMOD 0777 permissions (in your FTP application, right click on that file, choose Properties, then select Read, Write, and Execute options).
2. Create a PHP file (named usersontxt.php) having the code below, then copy this php file in the same directory as userson.txt.

The code for usersontxt.php;

<?php
// Script Online Users and Visitors - http://coursesweb.net/php-mysql/
if(!isset($_SESSION)) session_start();        // start Session, if not already started

$filetxt = 'userson.txt';  // the file in which the online users /visitors are stored
$timeon = 120;             // number of secconds to keep a user online
$sep = '^^';               // characters used to separate the user name and date-time
$vst_id = '-vst-';        // an identifier to know that it is a visitor, not logged user

/*
 If you have an user registration script,
 replace $_SESSION['nume'] with the variable in which the user name is stored.
 You can get a free registration script from:  http://coursesweb.net/php-mysql/register-login-script-users-online_s2
*/

// get the user name if it is logged, or the visitors IP (and add the identifier)

    $uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $_SERVER['SERVER_ADDR']. $vst_id;

$rgxvst = '/^([0-9\.]*)'. $vst_id. '/i';         // regexp to recognize the line with visitors
$nrvst = 0;                                       // to store the number of visitors

// sets the row with the current user /visitor that must be added in $filetxt (and current timestamp)

    $addrow[] = $uvon. $sep. time();

// check if the file from $filetxt exists and is writable

    if(is_writable($filetxt)) {
      // get into an array the lines added in $filetxt
      $ar_rows = file($filetxt, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
      $nrrows = count($ar_rows);

            // number of rows

  // if there is at least one line, parse the $ar_rows array

      if($nrrows>0) {
        for($i=0; $i<$nrrows; $i++) {
          // get each line and separate the user /visitor and the timestamp
          $ar_line = explode($sep, $ar_rows[$i]);
      // add in $addrow array the records in last $timeon seconds
          if($ar_line[0]!=$uvon && (intval($ar_line[1])+$timeon)>=time()) {
            $addrow[] = $ar_rows[$i];
          }
        }
      }
    }

$nruvon = count($addrow);                   // total online
$usron = '';                                    // to store the name of logged users
// traverse $addrow to get the number of visitors and users
for($i=0; $i<$nruvon; $i++) {
 if(preg_match($rgxvst, $addrow[$i])) $nrvst++;       // increment the visitors
 else {
   // gets and stores the user's name
   $ar_usron = explode($sep, $addrow[$i]);
   $usron .= '<br/> - <i>'. $ar_usron[0]. '</i>';
 }
}
$nrusr = $nruvon - $nrvst;              // gets the users (total - visitors)

// the HTML code with data to be displayed
$reout = '<div id="uvon"><h4>Online: '. $nruvon. '</h4>Visitors: '. $nrvst. '<br/>Users: '. $nrusr. $usron. '</div>';

// write data in $filetxt
if(!file_put_contents($filetxt, implode("\n", $addrow))) $reout = 'Error: Recording file not exists, or is not writable';

// if access from <script>, with GET 'uvon=showon', adds the string to return into a JS statement
// in this way the script can also be included in .html files
if(isset($_GET['uvon']) && $_GET['uvon']=='showon') $reout = "document.write('$reout');";

echo $reout;             // output /display the result
?>

3. If you want to include the script above in a ".php" file, add the following code in the place you want to show the number of online users and visitors:

4.To show the number of online visitors /users in a ".html" file, use this code:

<script type="text/javascript" src="usersontxt.php?uvon=showon"></script>

This script (and the other presented below) works with $_SESSION. At the beginning of the PHP file in which you use it, you must add: session_start();. Count Online users and visitors using a MySQL table

To register, count and show the number of online visitors and users in a MySQL table, require to perform three SQL queries: Delete the records older than a certain time. Insert a row with the new user /visitor, or, if it is already inserted, Update the timestamp in its column. Select the remaining rows. Here's the code for a script that uses a MySQL table (named "userson") to store and display the Online Users and Visitors.

1. First we create the "userson" table, with 2 columns (uvon, dt). In the "uvon" column is stored the name of the user (if logged in) or the visitor's IP. In the "dt" column is stored a number with the timestamp (Unix time) when the page is accessed.

• Add the following code in a php file (for example, named "create_userson.php"):

The code for create_userson.php:

<?php
header('Content-type: text/html; charset=utf-8');

// HERE add your data for connecting to MySQ database
$host = 'localhost';           // MySQL server address
$user = 'root';                // User name
$pass = 'password';            // User`s password
$dbname = 'database';          // Database name

// connect to the MySQL server
$conn = new mysqli($host, $user, $pass, $dbname);

// check connection
if (mysqli_connect_errno()) exit('Connect failed: '. mysqli_connect_error());

// sql query for CREATE "userson" TABLE
$sql = "CREATE TABLE `userson` (
 `uvon` VARCHAR(32) PRIMARY KEY,
 `dt` INT(10) UNSIGNED NOT NULL
 ) CHARACTER SET utf8 COLLATE utf8_general_ci"; 

// Performs the $sql query on the server to create the table
if ($conn->query($sql) === TRUE) echo 'Table "userson" successfully created';
else echo 'Error: '. $conn->error;

$conn->close();
?>

2. Now we create the script that Inserts, Deletes, and Selects data in the userson table (For explanations about the code, see the comments in script).

• Add the code below in another php file (named usersmysql.php): In both file you must add your personal data for connecting to MySQL database, in the variables: $host, $user, $pass, and $dbname .

The code for usersmysql.php:

<?php
// Script Online Users and Visitors - coursesweb.net/php-mysql/
if(!isset($_SESSION)) session_start();         // start Session, if not already started

// HERE add your data for connecting to MySQ database
$host = 'localhost';           // MySQL server address
$user = 'root';                // User name
$pass = 'password';            // User`s password
$dbname = 'database';          // Database name

/*
 If you have an user registration script,
 replace $_SESSION['nume'] with the variable in which the user name is stored.
 You can get a free registration script from:  http://coursesweb.net/php-mysql/register-login-script-users-online_s2
*/

// get the user name if it is logged, or the visitors IP (and add the identifier)
$vst_id = '-vst-';         // an identifier to know that it is a visitor, not logged user
$uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $_SERVER['SERVER_ADDR']. $vst_id;

$rgxvst = '/^([0-9\.]*)'. $vst_id. '/i';         // regexp to recognize the rows with visitors
$dt = time();                                    // current timestamp
$timeon = 120;             // number of secconds to keep a user online
$nrvst = 0;                                     // to store the number of visitors
$nrusr = 0;                                     // to store the number of usersrs
$usron = '';                                    // to store the name of logged users

// connect to the MySQL server
$conn = new mysqli($host, $user, $pass, $dbname);

// Define and execute the Delete, Insert/Update, and Select queries
$sqldel = "DELETE FROM `userson` WHERE `dt`<". ($dt - $timeon);
$sqliu = "INSERT INTO `userson` (`uvon`, `dt`) VALUES ('$uvon', $dt) ON DUPLICATE KEY UPDATE `dt`=$dt";
$sqlsel = "SELECT * FROM `userson`";

// Execute each query
if(!$conn->query($sqldel)) echo 'Error: '. $conn->error;
if(!$conn->query($sqliu)) echo 'Error: '. $conn->error;
$result = $conn->query($sqlsel);

// if the $result contains at least one row
if ($result->num_rows > 0) {
  // traverse the sets of results and set the number of online visitors and users ($nrvst, $nrusr)
  while($row = $result->fetch_assoc()) {
    if(preg_match($rgxvst, $row['uvon'])) $nrvst++;       // increment the visitors
    else {
      $nrusr++;                   // increment the users
      $usron .= '<br/> - <i>'.$row['uvon']. '</i>';          // stores the user's name
    }
  }
}

$conn->close();                  // close the MySQL connection

// the HTML code with data to be displayed
$reout = '<div id="uvon"><h4>Online: '. ($nrusr+$nrvst). '</h4>Visitors: '. $nrvst. '<br/>Users: '. $nrusr. $usron. '</div>';

// if access from <script>, with GET 'uvon=showon', adds the string to return into a JS statement
// in this way the script can also be included in .html files
if(isset($_GET['uvon']) && $_GET['uvon']=='showon') $reout = "document.write('$reout');";

echo $reout;             // output /display the result
?>

3. After you have created these two php files on your server, run the "create_userson.php" on your browser to create the "userson" table.

4. Include the usersmysql.php file in the php file in which you want to display the number of online users and visitors.

5. Or, if you want to insert it in a ".html" file, add this code:

Examples using these scripts

• Including the "usersontxt.php` in a php file:

<!doctype html>

• Including the "usersmysql.php" in a html file:

<!doctype html>
<html>
<head>
 <meta charset="utf-8" />
 <title>Counter Online Users and Visitors</title>
 <meta name="description" content="PHP script to count and show the number of online users and visitors" />
 <meta name="keywords" content="online users, online visitors" />
</head>
<body>

<!-- Includes the script ("usersontxt.php", or "usersmysql.php") -->
<script type="text/javascript" src="usersmysql.php?uvon=showon"></script>

</body>
</html>

Both scripts (with storing data in a text file on the server, or into a MySQL table) will display a result like this: Online: 5

Visitors: 3 Users: 2

The problem is that every System.BadImageFormatException: Could not load file or assembly including the ones not associated with installutil.exe at all point to this very thread.

1. If your issue is related to WindowsBase or PresentationFramework dlls and you got analyzers installed make sure to either have them installed for all of the projects in your solution or for none of them.

   

2. Reference the entire framework in .csproj file of your library rather than just the two dlls:

   <Project Sdk="Microsoft.NET.Sdk.WindowsDesktop">
   
     <PropertyGroup>
       <OutputType>Library</OutputType>
       <TargetFramework>netcoreapp3.0</TargetFramework>
       <RazorLangVersion>3.0</RazorLangVersion>
       <UseWpf>True</UseWpf>
     </PropertyGroup>
   

3. Remove bin and obj dirs, clean solution and rebuild.

Here is one combining noquote and paste:

noquote(paste("Argument is of length zero",sQuote("!"),"and",dQuote("double")))


#[1] Argument is of length zero ‘!’ and “double”

You mean remote debug JBoss from Eclipse ?

From Configuring Eclipse for Remote Debugging:

Set the JAVA_OPTS variable as follows:

set JAVA_OPTS= -Xdebug -Xnoagent 
   -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n %JAVA_OPTS%

or:

JAVA_OPTS="-Xdebug -Xnoagent 
  -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n $JAVA_OPTS"

In the Debug frame, select the Remote Java Application node.

In the Connection Properties, specify localhost as the Host and specify the Port as the port that was specified in the run batch script of the JBoss server, 8787.

select sys_extract_utc(systimestamp) from dual;

Won't work on Oracle 8, though.

What you want is an implementation of the observer pattern. You can do it yourself completely, or use java classes like java.util.Observer and java.util.Observable

In it's simplest form, use the answer of Georg Fritzsche

For a bit advanced, you can use this,

QString QString::arg ( int a, int fieldWidth = 0, int base = 10, const QChar & fillChar = QLatin1Char( ' ' ) ) const

Get the documentation and an example here..

There is also a property resourceRef of JndiObjectFactoryBean that is, when set to true, used to automatically prepend the string java:comp/env/ if it is not already present.

<bean id="someId" class="org.springframework.jndi.JndiObjectFactoryBean">
  <property name="jndiName" value="jdbc/loc"/>
  <property name="resourceRef" value="true"/>
</bean>

Direct Javascript calls between frames and/or windows are only allowed if they conform to the same-origin policy. If your window and iframe share a common parent domain you can set document.domain to "domain lower") one or both such that they can communicate. Otherwise you'll need to look into something like the postMessage() API.

Adding . before \r\n makes it work if the original string before \r\n has no .

Other characters may work. I didn't try.

With or without the three lines including IsBodyHtml, not a matter.

you can use CONVERT(TIME,GETDATE()) in this case:

INSERT INTO infoTbl
(itDate, itTime)
VALUES (GETDATE(),CONVERT(TIME,GETDATE()))

or if you want print it or return that time use like this:

DECLARE @dt TIME
SET @dt = CONVERT(TIME,GETDATE())
PRINT @dt

#include <stdbool.h>

Django database objects use the same save() method for creating and changing objects.

obj = Product.objects.get(pk=pk)
obj.name = "some_new_value"
obj.save()

How Django knows to UPDATE vs. INSERT
If the object’s primary key attribute is set to a value that evaluates to True (i.e., a value other than None or the empty string), Django executes an UPDATE. If the object’s primary key attribute is not set or if the UPDATE didn’t update anything, Django executes an INSERT.

 $('div#imageContainer').click(function () {
      $('div#imageContainerimg').attr('src', 'YOUR NEW IMAGE URL HERE'); 
});

You can do it with IE 'sometimes' as I have done this for an internal application on an intranet which is IE only. Try the following:

function GetComputerName() {
    try {
        var network = new ActiveXObject('WScript.Network');
        // Show a pop up if it works
        alert(network.computerName);
    }
    catch (e) { }
}

It may or may not require some specific security setting setup in IE as well to allow the browser to access the ActiveX object.

Here is a link to some more info on WScript: More Information

1. Open a command prompt as an Administrator.

2. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.

3. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.

4. Enter slmgr /rearm and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.

This should put the system back to a pre-key state.

Hope this helps you out!

Sorry to resurrect an old question, but I thought I might contribute a couple of very basic examples and for-dummies explanations. None of the other answers posted thusfar illustrate syntax like the MDN guide's first example, which is about as basic as one can get.

Getter:

var settings = {
    firstname: 'John',
    lastname: 'Smith',
    get fullname() { return this.firstname + ' ' + this.lastname; }
};

console.log(settings.fullname);

... will log John Smith, of course. A getter behaves like a variable object property, but offers the flexibility of a function to calculate its returned value on the fly. It's basically a fancy way to create a function that doesn't require () when calling.

Setter:

var address = {
    set raw(what) {
        var loc = what.split(/\s*;\s*/),
        area = loc[1].split(/,?\s+(\w{2})\s+(?=\d{5})/);

        this.street = loc[0];
        this.city = area[0];
        this.state = area[1];
        this.zip = area[2];
    }
};

address.raw = '123 Lexington Ave; New York NY  10001';
console.log(address.city);

... will log New York to the console. Like getters, setters are called with the same syntax as setting an object property's value, but are yet another fancy way to call a function without ().

See this jsfiddle for a more thorough, perhaps more practical example. Passing values into the object's setter triggers the creation or population of other object items. Specifically, in the jsfiddle example, passing an array of numbers prompts the setter to calculate mean, median, mode, and range; then sets object properties for each result.

You could use --where option on mysqldump to produce an output that you are waiting for:

mysqldump -u root -p test t1 --where="1=1 limit 100" > arquivo.sql

At most 100 rows from test.t1 will be dumped from database table.

The Helvetica font does not come included with Windows, so to use it you must download it as a .ttf file. Then you can refer matplotlib to it like this (replace "crm10.ttf" with your file):

import os
from matplotlib import font_manager as fm, rcParams
import matplotlib.pyplot as plt

fig, ax = plt.subplots()

fpath = os.path.join(rcParams["datapath"], "fonts/ttf/cmr10.ttf")
prop = fm.FontProperties(fname=fpath)
fname = os.path.split(fpath)[1]
ax.set_title('This is a special font: {}'.format(fname), fontproperties=prop)
ax.set_xlabel('This is the default font')

plt.show()

print(fpath) will show you where you should put the .ttf.

You can see the output here: https://matplotlib.org/gallery/api/font_file.html

If you have several versions of Python installed, /usr/bin/env will ensure the interpreter used is the first one on your environment's $PATH. The alternative would be to hardcode something like #!/usr/bin/python; that's ok, but less flexible.

In Unix, an executable file that's meant to be interpreted can indicate what interpreter to use by having a #! at the start of the first line, followed by the interpreter (and any flags it may need).

If you're talking about other platforms, of course, this rule does not apply (but that "shebang line" does no harm, and will help if you ever copy that script to a platform with a Unix base, such as Linux, Mac, etc).

Here is how I solved my problem:

Directive

app.directive("directive_name", function(){
    return {
        restrict: 'E',
        transclude: true,
        template: function(elem, attr){
           return '<div><h2>{{'+attr.scope+'}}</h2></div>';
        },
        replace: true
    };
})

Controller

$scope.building = function(data){
    var chart = angular.element(document.createElement('directive_name'));
    chart.attr('scope', data);
    $compile(chart)($scope);
    angular.element(document.getElementById('wrapper')).append(chart);
  }

I now can use different scopes through the same directive and append them dynamically.

1. A single bracket ([) usually actually calls a program named [; man test or man [ for more info. Example:

   $ VARIABLE=abcdef
   $ if [ $VARIABLE == abcdef ] ; then echo yes ; else echo no ; fi
   yes
   

2. The double bracket ([[) does the same thing (basically) as a single bracket, but is a bash builtin.

   $ VARIABLE=abcdef
   $ if [[ $VARIABLE == 123456 ]] ; then echo yes ; else echo no ; fi
   no
   

3. Parentheses (()) are used to create a subshell. For example:

   $ pwd
   /home/user 
   $ (cd /tmp; pwd)
   /tmp
   $ pwd
   /home/user
   

   As you can see, the subshell allowed you to perform operations without affecting the environment of the current shell.

4. (a) Braces ({}) are used to unambiguously identify variables. Example:

   $ VARIABLE=abcdef
   $ echo Variable: $VARIABLE
   Variable: abcdef
   $ echo Variable: $VARIABLE123456
   Variable:
   $ echo Variable: ${VARIABLE}123456
   Variable: abcdef123456
   

   (b) Braces are also used to execute a sequence of commands in the current shell context, e.g.

   $ { date; top -b -n1 | head ; } >logfile 
   # 'date' and 'top' output are concatenated, 
   # could be useful sometimes to hunt for a top loader )
   
   $ { date; make 2>&1; date; } | tee logfile
   # now we can calculate the duration of a build from the logfile
   

There is a subtle syntactic difference with ( ), though (see bash reference) ; essentially, a semicolon ; after the last command within braces is a must, and the braces {, } must be surrounded by spaces.

You can try:

$("._someDropDown").val();
