if anyone still having this problem. One solution is to rebuild the source OpenCV library using MinGW and not use the binaries given by OpenCV. I did it and it worked like a charm.

I totally agree with @jemmons:

But this should not be the default pattern you follow when dealing with blocks that call self! This should only be used to break what would otherwise be a retain cycle between self and the block. If you were to adopt this pattern everywhere, you'd run the risk of passing a block to something that got executed after self was deallocated.

//SUSPICIOUS EXAMPLE:
__weak MyObject *weakSelf = self;
[[SomeOtherObject alloc] initWithCompletion:^{
  //By the time this gets called, "weakSelf" might be nil because it's not  retained!
  [weakSelf doSomething];
}];

To overcome this problem one can define a strong reference over the weakSelf inside the block:

__weak MyObject *weakSelf = self;
[[SomeOtherObject alloc] initWithCompletion:^{
  MyObject *strongSelf = weakSelf;
  [strongSelf doSomething];
}];

No functions, no cursors. Try this

with cte as(
select CHAR(65) chr, 65 i 
union all
select CHAR(i+1) chr, i=i+1 from cte
where CHAR(i) <'Z'
)
select * from(
SELECT id, Case when LEN(data)>len(REPLACE(data, chr,'')) then chr+chr end data 
FROM table1, cte) x
where Data is not null

from msdn: public void Save (string filename); which is quite surprising to me because we dont just have to pass in the filename, we have to pass the filename along with the path for example: MyDirectory/MyImage.jpeg, here MyImage.jpeg does not actually exist yet, but our file will be saved with this name.

Another important point here is that if you are using Save() in a web application then use Server.MapPath() along with it which basically just returns the physical path for the virtual path which is passed in. Something like: image.Save(Server.MapPath("~/images/im111.jpeg"));

because you are just learning I suggest you practice converting a SELECT joins to UPDATE or DELETE joins. First I suggest you generate a SELECT statement joining these two tables:

SELECT *
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

Then note that we have two table aliases a and b. Using these aliases you can easily generate UPDATE statement to update either table a or b. For table a you have an answer provided by JW. If you want to update b, the statement will be:

UPDATE  b
SET     b.marks = a.marks
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

Now, to convert the statement to a DELETE statement use the same approach. The statement below will delete from a only (leaving b intact) for those records that match by name:

DELETE a
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

You can use the SQL Fiddle created by JW as a playground

Here is slightly modified version. Changes are noted as code commentary.

From .Net 3.5 you can use LINQ extension method that (sometimes) makes code flow a bit better.

Usage looks like this:

using System.Linq; 

// ...

public void My()
{
    var myArray = new[] { "abc", "123", "zyx" };
    List<string> myList = myArray.ToList();
}

PS. There's also ToArray() method that works in other way.

SIGABRT means in general that there is an uncaught exception. There should be more information on the console.

Close the cursor, if it is empty then deallocate it:

IF CURSOR_STATUS('global','myCursor') >= -1
 BEGIN
  IF CURSOR_STATUS('global','myCursor') > -1
   BEGIN
    CLOSE myCursor
   END
 DEALLOCATE myCursor
END

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

Sometimes this has to do with configuration changes. When we upgraded from Tomncat 6.0.14 to 6.0.26, we had seen something similar. here is the solution http://www.skill-guru.com/blog/2010/08/22/tomcat-6-0-26-shutdown-reports-a-web-application-created-a-threadlocal-threadlocal-has-been-forcibly-removed/

Maybe I write crappy code, but I've come to realize that clicking the trash-can icon on eclipse and netbeans IDEs is a 'good practice'.

On your Player class, implement the following two methods (substituting calls to encodeObject with something relevant to your own object):

- (void)encodeWithCoder:(NSCoder *)encoder {
    //Encode properties, other class variables, etc
    [encoder encodeObject:self.question forKey:@"question"];
    [encoder encodeObject:self.categoryName forKey:@"category"];
    [encoder encodeObject:self.subCategoryName forKey:@"subcategory"];
}

- (id)initWithCoder:(NSCoder *)decoder {
    if((self = [super init])) {
        //decode properties, other class vars
        self.question = [decoder decodeObjectForKey:@"question"];
        self.categoryName = [decoder decodeObjectForKey:@"category"];
        self.subCategoryName = [decoder decodeObjectForKey:@"subcategory"];
    }
    return self;
}

Reading and writing from NSUserDefaults:

- (void)saveCustomObject:(MyObject *)object key:(NSString *)key {
    NSData *encodedObject = [NSKeyedArchiver archivedDataWithRootObject:object];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:encodedObject forKey:key];
    [defaults synchronize];

}

- (MyObject *)loadCustomObjectWithKey:(NSString *)key {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSData *encodedObject = [defaults objectForKey:key];
    MyObject *object = [NSKeyedUnarchiver unarchiveObjectWithData:encodedObject];
    return object;
}

Code shamelessly borrowed from: saving class in nsuserdefaults

There is another example which I would like to share with you
:D http://www.sommarskog.se/dynamic_sql.html#cursor0

This is about object life-time management. Suppose you have more than singletons in your software. And they depend on Logger singleton. During application destruction, suppose another singleton object uses Logger to log its destruction steps. You have to guarantee that Logger should be cleaned up last. Therefore, please also check out this paper: http://www.cs.wustl.edu/~schmidt/PDF/ObjMan.pdf

Try This

SELECT @PrimaryContactKey = c.PrimaryCntctKey
FROM tarcustomer c, tarinvoice i
WHERE i.custkey = c.custkey 
    AND i.invckey = @tmp_key

UPDATE tarinvoice SET confirmtocntctkey = @PrimaryContactKey 
WHERE invckey = @tmp_key
FETCH NEXT FROM @get_invckey INTO @tmp_key

You would declare this variable outside of your loop as just a standard TSQL variable.

I should also note that this is how you would do it for any type of select into a variable, not just when dealing with cursors.

You could also sidestep nested cursor issues, general cursor issues, and global variable issues by avoiding the cursors entirely.

declare @rowid int
declare @rowid2 int
declare @id int
declare @type varchar(10)
declare @rows int
declare @rows2 int
declare @outer table (rowid int identity(1,1), id int, type varchar(100))
declare @inner table (rowid int  identity(1,1), clientid int, whatever int)

insert into @outer (id, type) 
Select id, type from sometable

select @rows = count(1) from @outer
while (@rows > 0)
Begin
    select top 1 @rowid = rowid, @id  = id, @type = type
    from @outer
    insert into @innner (clientid, whatever ) 
    select clientid whatever from contacts where contactid = @id
    select @rows2 = count(1) from @inner
    while (@rows2 > 0)
    Begin
        select top 1 /* stuff you want into some variables */
        /* Other statements you want to execute */
        delete from @inner where rowid = @rowid2
        select @rows2 = count(1) from @inner
    End  
    delete from @outer where rowid = @rowid
    select @rows = count(1) from @outer
End

In a single SQL query, without using the FOR XML clause.
A Common Table Expression is used to recursively concatenate the results.

-- rank locations by incrementing lexicographical order
WITH RankedLocations AS (
  SELECT
    VehicleID,
    City,
    ROW_NUMBER() OVER (
        PARTITION BY VehicleID 
        ORDER BY City
    ) Rank
  FROM
    Locations
),
-- concatenate locations using a recursive query
-- (Common Table Expression)
Concatenations AS (
  -- for each vehicle, select the first location
  SELECT
    VehicleID,
    CONVERT(nvarchar(MAX), City) Cities,
    Rank
  FROM
    RankedLocations
  WHERE
    Rank = 1

  -- then incrementally concatenate with the next location
  -- this will return intermediate concatenations that will be 
  -- filtered out later on
  UNION ALL

  SELECT
    c.VehicleID,
    (c.Cities + ', ' + l.City) Cities,
    l.Rank
  FROM
    Concatenations c -- this is a recursion!
    INNER JOIN RankedLocations l ON
        l.VehicleID = c.VehicleID 
        AND l.Rank = c.Rank + 1
),
-- rank concatenation results by decrementing length 
-- (rank 1 will always be for the longest concatenation)
RankedConcatenations AS (
  SELECT
    VehicleID,
    Cities,
    ROW_NUMBER() OVER (
        PARTITION BY VehicleID 
        ORDER BY Rank DESC
    ) Rank
  FROM 
    Concatenations
)
-- main query
SELECT
  v.VehicleID,
  v.Name,
  c.Cities
FROM
  Vehicles v
  INNER JOIN RankedConcatenations c ON 
    c.VehicleID = v.VehicleID 
    AND c.Rank = 1

That looks more explicit for me:

int? id = outputIdParam.Value is DbNull ? default(int?) : outputIdParam.Value;

I use inline if's

($_POST['category'] == $data['id'] ? 'selected="selected"' : false)

Code snippet above provides incorrect byte order in string, so I fixed it a bit.

char const hex[16] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A',   'B','C','D','E','F'};

std::string byte_2_str(char* bytes, int size) {
  std::string str;
  for (int i = 0; i < size; ++i) {
    const char ch = bytes[i];
    str.append(&hex[(ch  & 0xF0) >> 4], 1);
    str.append(&hex[ch & 0xF], 1);
  }
  return str;
}

Use this: htmlentities($_POST['field']);

Enough only. This for special character:

Use for CI htmlentities($this->input->post('control_name'));

By combining existing answers (this one and this one) the proper type safe way to add an ArrayList to a JComboBox is the following:

private DefaultComboBoxModel<YourClass> getComboBoxModel(List<YourClass> yourClassList)
{
    YourClass[] comboBoxModel = yourClassList.toArray(new YourClass[0]);
    return new DefaultComboBoxModel<>(comboBoxModel);
}

In your GUI code you set the entire list into your JComboBox as follows:

DefaultComboBoxModel<YourClass> comboBoxModel = getComboBoxModel(yourClassList);
comboBox.setModel(comboBoxModel);

See from How to Replace String in File works in a simple way and is an answer that works with replace

fin = open("data.txt", "rt")
fout = open("out.txt", "wt")

for line in fin:
    fout.write(line.replace('pyton', 'python'))

fin.close()
fout.close()

return; // Prematurely return from the method (same keword works in VB, by the way)

You can just use -i instead of -I {}

ls | xargs -i mv {} unix_{}

This also works perfectly.

• ls - lists all the files in the directory
• xargs - accepts all files line by line due to the -i option
• {} is the placeholder for all files, necessary if xargs gets more than two arguments as input

Using awk:

ls -lrt | grep '^-' | awk '{print "mv "$9" unix_"$9""}' | sh

The set statement doesn't treat spaces the way you expect; your variable is really named Pathname[space] and is equal to [space]C:\Program Files.

Remove the spaces from both sides of the = sign, and put the value in double quotes:

set Pathname="C:\Program Files"

Also, if your command prompt is not open to C:\, then using cd alone can't change drives.

Use

cd /d %Pathname%

or

pushd %Pathname%

instead.

I am using XAMPP on Ubuntu. I found this error when connecting database through terminal. I solve it without any configuration because default socket file path in XAMPP is written in "/opt/lampp/etc/my.cnf" as following:

[client]
#password   = your_password
port        = 3306
socket      = /opt/lampp/var/mysql/mysql.sock

now you can connect just by giving this socket path parameter with mysql command on terminal like:

mysql -u root --socket /opt/lampp/var/mysql/mysql.sock

and it's done without any configuration.

If you don't want to type socket path everytime, then go for changing default path in my.cnf by "/var/run/mysqld/mysqld.sock". Provide permissions and restart mysql server.

You can call .prop("tagName"). Examples:

jQuery("<a>").prop("tagName"); //==> "A"
jQuery("<h1>").prop("tagName"); //==> "H1"
jQuery("<coolTagName999>").prop("tagName"); //==> "COOLTAGNAME999"

If writing out .prop("tagName") is tedious, you can create a custom function like so:

jQuery.fn.tagName = function() {
  return this.prop("tagName");
};

Examples:

jQuery("<a>").tagName(); //==> "A"
jQuery("<h1>").tagName(); //==> "H1"
jQuery("<coolTagName999>").tagName(); //==> "COOLTAGNAME999"

Note that tag names are, by convention, returned CAPITALIZED. If you want the returned tag name to be all lowercase, you can edit the custom function like so:

jQuery.fn.tagNameLowerCase = function() {
  return this.prop("tagName").toLowerCase();
};

Examples:

jQuery("<a>").tagNameLowerCase(); //==> "a"
jQuery("<h1>").tagNameLowerCase(); //==> "h1"
jQuery("<coolTagName999>").tagNameLowerCase(); //==> "cooltagname999"

In ES2015 a.k.a ES6, class is a syntactic sugar for functions.

If you want to force to set a context for this you can use bind() method. As @chetan pointed, on invocation you can set the context as well! Check the example below:

class Form extends React.Component {
constructor() {
    super();
  }
  handleChange(e) {
    switch (e.target.id) {
      case 'owner':
        this.setState({owner: e.target.value});
        break;
      default:
    }
  }
  render() {
    return (
      <form onSubmit={this.handleNewCodeBlock}>
        <p>Owner:</p> <input onChange={this.handleChange.bind(this)} />
      </form>
    );
  }
}

Here we forced the context inside handleChange() to Form.

'&' --> '&'

'<' --> '&lt;'

'>' --> '&gt;'

You need to include the appropriate header

#include <stdio.h>

If you're not sure which header a standard function is defined in, the function's man page will state this.

Here's my standard implementation. I like the labels to be self-descriptive.

Public Sub DoSomething()

    On Error GoTo Catch ' Try
    ' normal code here

    Exit Sub
Catch:

    'error code: you can get the specific error by checking Err.Number

End Sub

Or, with a Finally block:

Public Sub DoSomething()

    On Error GoTo Catch ' Try

    ' normal code here

    GoTo Finally
Catch:

    'error code

Finally:

    'cleanup code

End Sub

Just use var = var1 var2 and it will automatically concatenate the vars var1 and var2:

awk '{new_var=$1$2; print new_var}' file

You can put an space in between with:

awk '{new_var=$1" "$2; print new_var}' file

Which in fact is the same as using FS, because it defaults to the space:

awk '{new_var=$1 FS $2; print new_var}' file

Test

$ cat file
hello how are you
i am fine
$ awk '{new_var=$1$2; print new_var}' file
hellohow
iam
$ awk '{new_var=$1 FS $2; print new_var}' file
hello how
i am

You can play around with it in ideone: http://ideone.com/4u2Aip

My very simple solution that worked: select another networkcard!

1. Make sure your guest is shut down
2. Goto the guest Settings > Network > Adavanced
3. Change the Adapter Type to another adapter.
4. Start your guest and check if you got a decent IP for your network.

If it doesn't work, repeat steps and try yet another network adapter. The very basic PCnet adapters have a high succes-rate.

Good luck.

You must assign it, like this:-

df['id']= df['id'].astype(str)

None of the answers above is doing the job.

Rob solution hangs and 'Mark Byers' solution get the disposed exception.(I tried the "solutions" of the other answers).

So I decided to suggest another solution:

public void GetProcessOutputWithTimeout(Process process, int timeoutSec, CancellationToken token, out string output, out int exitCode)
{
    string outputLocal = "";  int localExitCode = -1;
    var task = System.Threading.Tasks.Task.Factory.StartNew(() =>
    {
        outputLocal = process.StandardOutput.ReadToEnd();
        process.WaitForExit();
        localExitCode = process.ExitCode;
    }, token);

    if (task.Wait(timeoutSec, token))
    {
        output = outputLocal;
        exitCode = localExitCode;
    }
    else
    {
        exitCode = -1;
        output = "";
    }
}

using (var process = new Process())
{
    process.StartInfo = ...;
    process.Start();
    string outputUnicode; int exitCode;
    GetProcessOutputWithTimeout(process, PROCESS_TIMEOUT, out outputUnicode, out exitCode);
}

This code debugged and works perfectly.

I just did some tests of the four options that I know about.

Measure-Command {$(1..1000) | Out-Null}

TotalMilliseconds : 76.211

Measure-Command {[Void]$(1..1000)}

TotalMilliseconds : 0.217

Measure-Command {$(1..1000) > $null}

TotalMilliseconds : 0.2478

Measure-Command {$null = $(1..1000)}

TotalMilliseconds : 0.2122

## Control, times vary from 0.21 to 0.24
Measure-Command {$(1..1000)}

TotalMilliseconds : 0.2141

So I would suggest that you use anything but Out-Null due to overhead. The next important thing, to me, would be readability. I kind of like redirecting to $null and setting equal to $null myself. I use to prefer casting to [Void], but that may not be as understandable when glancing at code or for new users.

I guess I slightly prefer redirecting output to $null.

Do-Something > $null

Edit

After stej's comment again, I decided to do some more tests with pipelines to better isolate the overhead of trashing the output.

Here are some tests with a simple 1000 object pipeline.

## Control Pipeline
Measure-Command {$(1..1000) | ?{$_ -is [int]}}

TotalMilliseconds : 119.3823

## Out-Null
Measure-Command {$(1..1000) | ?{$_ -is [int]} | Out-Null}

TotalMilliseconds : 190.2193

## Redirect to $null
Measure-Command {$(1..1000) | ?{$_ -is [int]} > $null}

TotalMilliseconds : 119.7923

In this case, Out-Null has about a 60% overhead and > $null has about a 0.3% overhead.

Addendum 2017-10-16: I originally overlooked another option with Out-Null, the use of the -inputObject parameter. Using this the overhead seems to disappear, however the syntax is different:

Out-Null -inputObject ($(1..1000) | ?{$_ -is [int]})

And now for some tests with a simple 100 object pipeline.

## Control Pipeline
Measure-Command {$(1..100) | ?{$_ -is [int]}}

TotalMilliseconds : 12.3566

## Out-Null
Measure-Command {$(1..100) | ?{$_ -is [int]} | Out-Null}

TotalMilliseconds : 19.7357

## Redirect to $null
Measure-Command {$(1..1000) | ?{$_ -is [int]} > $null}

TotalMilliseconds : 12.8527

Here again Out-Null has about a 60% overhead. While > $null has an overhead of about 4%. The numbers here varied a bit from test to test (I ran each about 5 times and picked the middle ground). But I think it shows a clear reason to not use Out-Null.

In code to load resource in the executing assembly where my image 'Freq.png' was in the folder "Icons" and defined as "Resource".

        this.Icon = new BitmapImage(new Uri(@"pack://application:,,,/" 
             + Assembly.GetExecutingAssembly().GetName().Name 
             + ";component/" 
             + "Icons/Freq.png", UriKind.Absolute)); 

I also made a function if anybody would like it...

/// <summary>
/// Load a resource WPF-BitmapImage (png, bmp, ...) from embedded resource defined as 'Resource' not as 'Embedded resource'.
/// </summary>
/// <param name="pathInApplication">Path without starting slash</param>
/// <param name="assembly">Usually 'Assembly.GetExecutingAssembly()'. If not mentionned, I will use the calling assembly</param>
/// <returns></returns>
public static BitmapImage LoadBitmapFromResource(string pathInApplication, Assembly assembly = null)
{
    if (assembly == null)
    {
        assembly = Assembly.GetCallingAssembly();
    }

    if (pathInApplication[0] == '/')
    {
        pathInApplication = pathInApplication.Substring(1);
    }
    return new BitmapImage(new Uri(@"pack://application:,,,/" + assembly.GetName().Name + ";component/" + pathInApplication, UriKind.Absolute)); 
}

Usage:

        this.Icon = ResourceHelper.LoadBitmapFromResource("Icons/Freq.png");

Look in the SDK Manager what is your highest Android SDK Build-tools version, and copy this version number in your project build.gradle file, in the android/buildToolsVersion property (for me, version was "18.1.1").

Hope it help!

I followed below steps to install mcrypt for PHP7.2 using PECL.

1. Install PECL

apt-get install php-pecl

2. Before installing MCRYPT you must install libmcrypt

apt-get install libmcrypt-dev libreadline-dev

3. Install MCRYPT 1.0.1 using PECL

pecl install mcrypt-1.0.1

4. After the successful installation

You should add "extension=mcrypt.so" to php.ini

Please comment below if you need any assistance. :-)

IMPORTANT !

According to php.net reference many (all) mcrypt functions have been DEPRECATED as of PHP 7.1.0. Relying on this function is highly discouraged.

dir /s *foo* searches in current folder and sub folders.

It finds directories as well as files.

where /s means(documentation):

/s Lists every occurrence of the specified file name within the specified directory and all subdirectories.

Use implode

implode("|",$type);

Check out this jsfiddle.

HTML

// note the change... I set the disabled property right away
<input type="submit" id="register" value="Register" disabled="disabled" />

JavaScript

(function() {
    $('form > input').keyup(function() {

        var empty = false;
        $('form > input').each(function() {
            if ($(this).val() == '') {
                empty = true;
            }
        });

        if (empty) {
            $('#register').attr('disabled', 'disabled'); // updated according to http://stackoverflow.com/questions/7637790/how-to-remove-disabled-attribute-with-jquery-ie
        } else {
            $('#register').removeAttr('disabled'); // updated according to http://stackoverflow.com/questions/7637790/how-to-remove-disabled-attribute-with-jquery-ie
        }
    });
})()

The nice thing about this is that it doesn't matter how many input fields you have in your form, it will always keep the button disabled if there is at least 1 that is empty. It also checks emptiness on the .keyup() which I think makes it more convenient for usability.

jQuery recently started using source maps.

For example, let's look at the minified jQuery 2.0.3 file's first few lines.

/*! jQuery v2.0.3 | (c) 2005, 2013 jQuery Foundation, Inc. | jquery.org/license
//@ sourceMappingURL=jquery.min.map
*/

Excerpt from Introduction to JavaScript Source Maps:

Have you ever found yourself wishing you could keep your client-side code readable and more importantly debuggable even after you've combined and minified it, without impacting performance? Well now you can through the magic of source maps.

Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location. Developer tools (currently WebKit nightly builds, Google Chrome, or Firefox 23+) can parse the source map automatically and make it appear as though you're running unminified and uncombined files.

^{emphasis mine}

It's incredibly useful, and will only download if the user opens dev tools.

Solution

Remove the source mapping line, or do nothing. It isn't really a problem.

Side note: your server should return 404, not 500. It could point to a security problem if this happens in production.

I want to extend Olcay's nice answer. His approach is good, your login page controller should be like this to put the referrer url into session:

@RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginPage(HttpServletRequest request, Model model) {
    String referrer = request.getHeader("Referer");
    request.getSession().setAttribute("url_prior_login", referrer);
    // some other stuff
    return "login";
}

And you should extend SavedRequestAwareAuthenticationSuccessHandler and override its onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) method. Something like this:

public class MyCustomLoginSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {
    public MyCustomLoginSuccessHandler(String defaultTargetUrl) {
        setDefaultTargetUrl(defaultTargetUrl);
    }

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws ServletException, IOException {
        HttpSession session = request.getSession();
        if (session != null) {
            String redirectUrl = (String) session.getAttribute("url_prior_login");
            if (redirectUrl != null) {
                // we do not forget to clean this attribute from session
                session.removeAttribute("url_prior_login");
                // then we redirect
                getRedirectStrategy().sendRedirect(request, response, redirectUrl);
            } else {
                super.onAuthenticationSuccess(request, response, authentication);
            }
        } else {
            super.onAuthenticationSuccess(request, response, authentication);
        }
    }
}

Then, in your spring configuration, you should define this custom class as a bean and use it on your security configuration. If you are using annotation config, it should look like this (the class you extend from WebSecurityConfigurerAdapter):

@Bean
public AuthenticationSuccessHandler successHandler() {
    return new MyCustomLoginSuccessHandler("/yourdefaultsuccessurl");
}

In configure method:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
            // bla bla
            .formLogin()
                .loginPage("/login")
                .usernameParameter("username")
                .passwordParameter("password")
                .successHandler(successHandler())
                .permitAll()
            // etc etc
    ;
}

This is a bit off, but if you have an event that triggers switch, you can do without classes:

<div id="classOne1"></div>
<div id="classOne2"></div>
<div id="classTwo3"></div>

You can do

$('body').click( function() {

    switch ( this.id.replace(/[0-9]/g, '') ) {
        case 'classOne': this.innerHTML = "I have classOne"; break;
        case 'classTwo': this.innerHTML = "I have classTwo"; break;
        default: this.innerHTML = "";
    }

});

.replace(/[0-9]/g, '') removes digits from id.

It is a bit hacky, but works for long switches without extra functions or loops

A solution that works no matter if you are developing on a local server or live is to add "//" in front of your link. This will effectivly remove the URL of the site you are currently on.

Example:

<a href="www.google.com">Google.com</a>

This will in output http://localhost/mySite/currentPage/www.google.com

What you should do instead is this:

<a href="//www.google.com">Google.com</a>

This will output www.google.com

To fix your code you can simply change [Cov] to Cov.values, the first parameter of pd.DataFrame will become a multi-dimensional numpy array:

Cov = pd.read_csv("path/to/file.txt", sep='\t')
Frame=pd.DataFrame(Cov.values, columns = ["Sequence", "Start", "End", "Coverage"])
Frame.to_csv("path/to/file.txt", sep='\t')

But the smartest solution still is use pd.read_excel with header=None and names=columns_list.

This steps are all in the terminal:)->source

1. Step make sure your server is running:

sudo /usr/local/mysql/support-files/mysql.server start

2. Check MySQL version. "This also puts you in to a shell interactive dialogue with mySQL, type q to exit."

/usr/local/mysql/bin/mysql -v

3. Make your life easier: "After installation, in order to use mysql commands without typing the full path to the commands you need to add the mysql directory to your shell path, (optional step) this is done in your “.bash_profile” file in your home directory, if you don’t have that file just create it using vi or nano:"

cd ; nano .bash_profile

paste in and save:

export PATH="/usr/local/mysql/bin:$PATH"

"The first command brings you to your home directory and opens the .bash_profile file or creates a new one if it doesn’t exist, then add in the line above which adds the mysql binary path to commands that you can run. Exit the file with type “control + x” and when prompted save the change by typing “y”. Last thing to do here is to reload the shell for the above to work straight away."

source ~/.bash_profile mysql -v

"You will get the version number again, just type “q” to exit."

4. Check out on which port the server is running:

in your terminal type in: mysql

and then

SHOW GLOBAL VARIABLES LIKE 'PORT';

use everytime a semikolon in the mysql client (shell)!

now you know your port and where you can configure your server(in the terminal with mysql shell/client). but for a successful connection with MySQL Benchmark or an other client you have to know more. username, passwort hostname and port. after the installation the root user has no passwort so set(howtoSetPW) the passwort in terminal with mysql shell/client. and the server is running local. so type in root, yourPW, localhost and 3007. have fun!

Check by using mod - if there is a remainder, simply increment the value by one.

By default Ansible will attempt to run on all hosts in parallel. See these Ansible docs for details. You can also use the serial parameter to limit the number of parallel hosts you want to be processed at any given time, so if you want to have a playbook run on just one host at a time you can specify serial:1, etc.

Ansible is designed so that each task will be run on all hosts before continuing on to the next task. So if you have 3 tasks it will ensure task 1 runs on all your hosts first, then task 2 is run, then task 3 is run. See this section of the Ansible docs for more details on this.

I like to give my input field a border, remove the outline on focus, and "outline" the border instead:

input {
  border: 1px solid grey;

  &:focus {
    outline: none;
    border-left: 1px solid violet;
  }
 }

You can also do it with a transparent border:

input {
  border: 1px solid transparent;

  &:focus {
    outline: none;
    border-left: 1px solid violet;
  }
 }

Try following or check demo disabled and readonly

$('#dropUnit').is(':disabled') //Returns bool
$('#dropUnit').attr('readonly') == "readonly"  //If Condition

You can check jQuery FAQ .

There is a method in Guava Sets which can help here:

public static <E>  boolean equals(Set<? extends E> set1, Set<? extends E> set2){
return Sets.symmetricDifference(set1,set2).isEmpty();
}

AllDogs.First(d => d.Id == "2").Name = "some value";

However, a safer version of that might be this:

var dog = AllDogs.FirstOrDefault(d => d.Id == "2");
if (dog != null) { dog.Name = "some value"; }

This is much shorter in code than using show() and hide() methods.

Don't type python test.py from inside the Python interpreter. Type it at the command prompt, like so:

In Card Range Recognition (CRR), a drawback with algorithms that use a series of regex or other hard-coded ranges, is that the BINs/IINs do change over time in my experience. The co-branding of cards is an ongoing complication. Different Card Acquirers / merchants may need you treat the same card differently, depending on e.g. geolocation.

Additionally, in the last few years with e.g. UnionPay cards in wider circulation, existing models do not cope with new ranges that sometimes interleave with broader ranges that they supersede.
Knowing the geography your system needs to cover may help, as some ranges are restricted to use in particular countries. For example, ranges 62 include some AAA sub-ranges in the US, but if your merchant base is outside the US, you may be able to treat all 62 as UnionPay.
You may be also asked to treat a card differently based on merchant location. E.g. to treat certain UK cards as debit domestically, but as credit internationally.

There are very useful set of rules maintained by one major Acquiring Bank. E.g. https://www.barclaycard.co.uk/business/files/BIN-Rules-EIRE.pdf and https://www.barclaycard.co.uk/business/files/BIN-Rules-UK.pdf. (Valid links as of June 2017, thanks to the user who provided a link to updated reference.) But be aware of the caveat that, while these CRR rules may represent the Card Issuing universe as it applies to the merchants acquired by that entity, it does not include e.g. ranges identified as CUP/UPI.

These comments apply to magnetic stripe (MagStripe) or PKE (Pan Key Entry) scenarios. The situation is different again in the ICC/EMV world.

Update: Other answers on this page (and also the linked WikiPedia page) have JCB as always 16 long. However, in my company we have a dedicated team of engineers who certify our POS devices and software across multiple acquiring banks and geographies. The most recent Certification Pack of cards this team have from JCB, had a pass case for a 19 long PAN.

It seems strange that you would write arrays without commas (is that a MATLAB syntax?)

Have you tried going through NumPy's documentation on multi-dimensional arrays?

It seems NumPy has a "Python-like" append method to add items to a NumPy n-dimensional array:

>>> p = np.array([[1,2],[3,4]])

>>> p = np.append(p, [[5,6]], 0)

>>> p = np.append(p, [[7],[8],[9]],1)

>>> p
array([[1, 2, 7], [3, 4, 8], [5, 6, 9]])

It has also been answered already...

From the documentation for MATLAB users:

You could use a matrix constructor which takes a string in the form of a matrix MATLAB literal:

mat("1 2 3; 4 5 6")

or

matrix("[1 2 3; 4 5 6]")

Please give it a try and tell me how it goes.

I think you should be able to follow the method used in this post. It looks really ugly, but I would think you could do it twice and get the result you want.

I wonder if this is actually a case where you'd be better off using DataContext.ExecuteCommand(...) instead of converting to linq.

Edit: Harhar is now open source. I have updated the URL below.

If you use an Avalanche load generator, you can use Harhar to replay a HAR file at very high load: https://acastaner.github.io/harhar/

This tool handles the "content" you use when you "Save as HAR with content."

I was facing the same issue, I made below changes and the issue got resolved.

Open watchQueryOptions.d.ts file

\apollo-client\core\watchQueryOptions.d.ts

Change the query type any instead of DocumentNode, Same for mutation

Before:

export interface QueryBaseOptions<TVariables = OperationVariables> {
    query: **DocumentNode**;

After:

export interface QueryBaseOptions<TVariables = OperationVariables> {
    query: **any**;

You have got the PATH slightly wrong. You need the PATH to "the containing directory", not the actual executable itself.

Your PATH should be set like this:

export PATH=/Library/PostgreSQL/9.5/bin:$PATH

without the extra sql part in it. Also, you must remove the spaces around the equals sign.

Keywords: Postgresql, PATH, macOS, OSX, psql

After upgrading to Mountain Lion using the NDK, I had the following error:

Cannot find 'make' program. Please install Cygwin make package or define the GNUMAKE variable to point to it

Error was fixed by downloading and using the latest NDK

In php.ini set :

error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT

From C++ Primer:

The istringstream type reads a string, ostringstream writes a string, and stringstream reads and writes the string.

I come across some cases where it is both convenient and concise to use stringstream.

case 1

It is from one of the solutions for this leetcode problem. It demonstrates a very suitable case where the use of stringstream is efficient and concise.

Suppose a and b are complex numbers expressed in string format, we want to get the result of multiplication of a and b also in string format. The code is as follows:

string a = "1+2i", b = "1+3i";
istringstream sa(a), sb(b);
ostringstream out;

int ra, ia, rb, ib;
char buff;
// only read integer values to get the real and imaginary part of 
// of the original complex number
sa >> ra >> buff >> ia >> buff;
sb >> rb >> buff >> ib >> buff;

out << ra*rb-ia*ib << '+' << ra*ib+ia*rb << 'i';

// final result in string format
string result = out.str() 

case 2

It is also from a leetcode problem that requires you to simplify the given path string, one of the solutions using stringstream is the most elegant that I have seen:

string simplifyPath(string path) {
    string res, tmp;
    vector<string> stk;
    stringstream ss(path);
    while(getline(ss,tmp,'/')) {
        if (tmp == "" or tmp == ".") continue;
        if (tmp == ".." and !stk.empty()) stk.pop_back();
        else if (tmp != "..") stk.push_back(tmp);
    }
    for(auto str : stk) res += "/"+str;
    return res.empty() ? "/" : res; 
 }

Without the use of stringstream, it would be difficult to write such concise code.

$('input[type="submit"]').click(function(){
$(this).css('color','red');
});

Use class, Demo:- http://jsfiddle.net/BX6Df/

   $('input[type="submit"]').click(function(){
          $(this).addClass('red');
});

if you want to toggle the color each click, you can try this:- http://jsfiddle.net/SMNks/

$('input[type="submit"]').click(function(){
  $(this).toggleClass('red');
});


.red
{
    background-color:red;
}

Updated answer for your comment.

http://jsfiddle.net/H2Xhw/

$('input[type="submit"]').click(function(){
    $('input[type="submit"].red').removeClass('red')
        $(this).addClass('red');
});

Use a function like this:

    public static string FlattenException(Exception exception)
    {
        var stringBuilder = new StringBuilder();

        while (exception != null)
        {
            stringBuilder.AppendLine(exception.Message);
            stringBuilder.AppendLine(exception.StackTrace);

            exception = exception.InnerException;
        }

        return stringBuilder.ToString();
    }

Then you can call it like this:

try
{
    // invoke code above
}
catch(MyCustomException we)
{
    Debug.Writeline(FlattenException(we));
}

No.

The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.

You can combine the use of Content-Disposition with other content-types, such as image/png or even text/html to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).

RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.

Hence:

Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"

Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"

Means "This is a PNG image. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: inline; filename="picture.png"

Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".

Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).

Check following link. This would be helpful too..

In Parent Window:

function OpenChildAsPopup() {
        var childWindow = window.open("ChildWindow.aspx", "_blank",
        "width=200px,height=350px,left=200,top=100");
        childWindow.focus();
 }

function ChangeBackgroudColor() {
        var para = document.getElementById('samplePara');
        if (para !="undefied") {
            para.style.backgroundColor = '#6CDBF5';
        }
 }

Parent Window HTML Markup:

<div>
  <p id="samplePara" style="width: 350px;">
            Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
  </p><br />
 <asp:Button ID="Button1" Text="Open Child Window" 
         runat="server" OnClientClick="OpenChildAsPopup();"/>
</div>

In Child Window:

// This will be called when the child window is closed.     
  window.onunload = function (e) {
        opener.ChangeBackgroudColor();
        //or you can do
        //var para = opener.document.getElementById('samplePara');
        //if (para != "undefied") {
        //    para.style.backgroundColor = '#6CDBF5';
        //}
    };

For basic URL resolution, use a command line fetcher like wget or curl to do the testing, rather than a manual browser. Then you don't have to clear any cache; just up arrow and Enter in a shell to re-run your test fetches.

You can use one of the following methods:

document.getElementById('log').innerHTML = "text";

document.getElementById('log').innerText = "text";

document.getElementById('log').textContent = "text";

For Jquery:

$("#log").text("text");

$("#log").html("text");

Sound like you want to UNPIVOT

Sample from books online:

--Create the table and insert values as portrayed in the previous example.
CREATE TABLE pvt (VendorID int, Emp1 int, Emp2 int,
    Emp3 int, Emp4 int, Emp5 int);
GO
INSERT INTO pvt VALUES (1,4,3,5,4,4);
INSERT INTO pvt VALUES (2,4,1,5,5,5);
INSERT INTO pvt VALUES (3,4,3,5,4,4);
INSERT INTO pvt VALUES (4,4,2,5,5,4);
INSERT INTO pvt VALUES (5,5,1,5,5,5);
GO
--Unpivot the table.
SELECT VendorID, Employee, Orders
FROM 
   (SELECT VendorID, Emp1, Emp2, Emp3, Emp4, Emp5
   FROM pvt) p
UNPIVOT
   (Orders FOR Employee IN 
      (Emp1, Emp2, Emp3, Emp4, Emp5)
)AS unpvt;
GO

Returns:

VendorID   Employee   Orders
---------- ---------- ------
1          Emp1       4
1          Emp2       3
1          Emp3       5
1          Emp4       4
1          Emp5       4
2          Emp1       4
2          Emp2       1
2          Emp3       5
2          Emp4       5
2          Emp5       5

I also tried executing batch file that run daemon process/server at the end of CCNET task; The only way to make CruiseControl spawn an independent asynchronous process WITHOUT waiting for the end of process is:

1. create a batch file to run the daemon process (server application)

2. use task scheduler to run the batch file as CCNET task (using schtasks.exe)

   schtasks.exe /create /F /SC once /ST 08:50 /TN TaskName /TR "c:/path/to/batchFileName.bat"
   

   • 08:50 is the HH:MM time format

you might need to kill the process at the start of ccnet

PS: the selected answer using "start cmd.exe" does not work; a new command prompt is indeed spawned, but CCNET will wait for the spawned cmd to finish.

Typically searching for three consecutive lines in Powershell it would look like:

$file = get-content file.txt -raw

$pattern = 'lineone\r\nlinetwo\r\nlinethree\r\n'     # "windows" text
$pattern = 'lineone\nlinetwo\nlinethree\n'           # "unix" text
$pattern = 'lineone\r?\nlinetwo\r?\nlinethree\r?\n'  # both

$file -match $pattern

# output
True

Bizarrely, this would be unix text at the prompt, but windows text in a file:

$pattern = 'lineone
linetwo
linethree
'

Here's a way to print out the line endings:

'lineone
linetwo
linethree
' -replace "`r",'\r' -replace "`n",'\n'

# output
lineone\nlinetwo\nlinethree\n

Strings are slower in joins and in real life they are very rarely really unique (even when they are supposed to be). The only advantage is that they can reduce the number of joins if you are joining to the primary table only to get the name. However, strings are also often subject to change thus creating the problem of having to fix all related records when the company name changes or the person gets married. This can be a huge performance hit and if all tables that should be related somehow are not related (this happens more often than you think), then you might have data mismatches as well. An integer that will never change through the life of the record is a far safer choice from a data integrity standpoint as well as from a performance standpoint. Natural keys are usually not so good for maintenance of the data.

I also want to point out that the best of both worlds is often to use an autoincrementing key (or in some specialized cases, a GUID) as the PK and then put a unique index on the natural key. You get the faster joins, you don;t get duplicate records, and you don't have to update a million child records because a company name changed.

Try

Dim connectionString AS String = "Server=my_server;Database=name_of_db;User Id=user_name;Password=my_password"

And replace my_server, name_of_db, user_name and my_password with your values.

then Using sqlCon = New SqlConnection(connectionString) should work

also I think your SQL is wrong, it should be SET clickCount= clickCount + 1 I think.

And on a general note, the page you link to has a link called Connection String which shows you how to do this.

There is a companion tool called Oracle Data Modeler that you could take a look at. There are online demos available at the site that will get you started. It used to be an added cost item, but I noticed that once again it's free.

From the Data Modeler overview page:

SQL Developer Data Modeler is a free data modeling and design tool, proving a full spectrum of data and database modeling tools and utilities, including modeling for Entity Relationship Diagrams (ERD), Relational (database design), Data Type and Multi-dimensional modeling, with forward and reverse engineering and DDL code generation. The Data Modeler imports from and exports to a variety of sources and targets, provides a variety of formatting options and validates the models through a predefined set of design rules.

They are implemented in very different ways.

hash_map (unordered_map in TR1 and Boost; use those instead) use a hash table where the key is hashed to a slot in the table and the value is stored in a list tied to that key.

map is implemented as a balanced binary search tree (usually a red/black tree).

An unordered_map should give slightly better performance for accessing known elements of the collection, but a map will have additional useful characteristics (e.g. it is stored in sorted order, which allows traversal from start to finish). unordered_map will be faster on insert and delete than a map.

As everybody says, bash doesn't have a proper language-supported try/catch syntax. You can launch bash with the -e argument or use set -e inside the script to abort the entire bash process if any command has a non-zero exit code. (You can also set +e to temporarily allow failing commands.)

So, one technique to simulate a try/catch block is to launch a sub-process to do the work with -e enabled. Then in the main process, check the return code of the sub-process.

Bash supports heredoc strings, so you don't have to write two separate files to handle this. In the below example, the TRY heredoc will run in a separate bash instance, with -e enabled, so the sub-process will crash if any command returns a non-zero exit code. Then, back in the main process, we can check the return code to handle a catch block.

#!/bin/bash

set +e
bash -e <<TRY
  echo hello
  cd /does/not/exist
  echo world
TRY
if [ $? -ne 0 ]; then
  echo caught exception
fi

It's not a proper language-supported try/catch block, but it may scratch a similar itch for you.

For this to work, your font also needs to be set to monospace.
If you think about it, lines can't otherwise line up perfectly perfectly.

This answer is detailed at sublime text forum:
http://www.sublimetext.com/forum/viewtopic.php?f=3&p=42052
This answer has links for choosing an appropriate font for your OS,
and gives an answer to an edge case of fonts not lining up.

Another website that lists great monospaced free fonts for programmers. http://hivelogic.com/articles/top-10-programming-fonts

On stackoverflow, see:

Michael Ruth's answer here: How to make ruler always be shown in Sublime text 2?

MattDMo's answer here: What is the default font of Sublime Text?

I have rulers set at the following:
30
50 (git commit message titles should be limited to 50 characters)
72 (git commit message details should be limited to 72 characters)
80 (Windows Command Console Window maxes out at 80 character width)

Other viewing environments that benefit from shorter lines: github: there is no word wrap when viewing a file online
So, I try to keep .js .md and other files at 70-80 characters.
Windows Console: 80 characters.

We can change context root path using a simple entry in the properties file.

application.properties

### Spring boot 1.x #########
server.contextPath=/ClientApp

### Spring boot 2.x #########
server.servlet.context-path=/ClientApp

My answer is a mod of some prior answers from @JoeMills and @user.

1. Get a cURL command to log into server:

   • Load login page for website and open Network pane of Developer Tools
     • In firefox, right click page, choose 'Inspect Element (Q)' and click on Network tab
   • Go to login form, enter username, password and log in
   • After you have logged in, go back to Network pane and scroll to the top to find the POST entry. Right click and choose Copy -> Copy as CURL
   • Paste this to a text editor and try this in command prompt to see if it works
     • Its possible that some sites have hardening that will block this type of login spoofing that would require more steps below to bypass.

2. Modify cURL command to be able to save session cookie after login

   • Remove the entry -H 'Cookie: <somestuff>'
   • Add after curl at beginning -c login_cookie.txt
   • Try running this updated curl command and you should get a new file 'login_cookie.txt' in the same folder

3. Call a new web page using this new cookie that requires you to be logged in

   • curl -b login_cookie.txt <url_that_requires_log_in>

I have tried this on Ubuntu 20.04 and it works like a charm.

Use event.key instead of event.keyCode!

function onEvent(event) {
    if (event.key === "Enter") {
        // Submit form
    }
};

I implemented many automation cases based on REST Assured , a jave DSL for testing restful service. https://code.google.com/p/rest-assured/

The syntax is easy, it supports json and xml. https://code.google.com/p/rest-assured/wiki/Usage

Before that, I tried SOAPUI and had some issues with the free version. Plus the cases are in xml files which hard to extend and reuse, simply I don't like

Here is full code. The result is exactly what you want.

class Animal(object):
    def __init__(self):
        self.legs = 2
        self.name = 'Dog'
        self.color= 'Spotted'
        self.smell= 'Alot'
        self.age  = 10
        self.kids = 0

if __name__ == '__main__':
    animal = Animal()
    temp = vars(animal)
    for item in temp:
        print item , ' : ' , temp[item]
        #print item , ' : ', temp[item] ,

function getCount(){
    return $this->db->get('table_name')->num_rows();
}

Use the span tag

<style>
    .redText
    {
        color:red;
    }
    .blackText
    {
        color:black;
        font-weight:bold;
    }
</style>

<span class="redText">My Name is:</span>&nbsp;<span class="blackText">Tintincute</span>

It's also a good idea to avoid inline styling. Use a custom CSS class instead.

Try this

SELECT ID, Name 
FROM   Table1 
WHERE  ID NOT IN (SELECT ID FROM Table2)

Since web is evolving quickly, some things changes with time. For security issues, you might want to use the rel="noopener" attribute in conjuncture with your target="_blank".

Like stated in Google Dev Documentation, the other page can access your window object with the window.opener property. Your external link should looks like this now:

<a href="http://www.starfall.com/" target="_blank" rel="noopener">Starfall</a>

Update: I have found a better/proper way to solve this problem using a BehaviorSubject or an Observable rather than an EventEmitter. Please see this answer: https://stackoverflow.com/a/35568924/215945

Also, the Angular docs now have a cookbook example that uses a Subject.

Original/outdated/wrong answer: again, don't use an EventEmitter in a service. That is an anti-pattern.

Using beta.1... NavService contains the EventEmiter. Component Navigation emits events via the service, and component ObservingComponent subscribes to the events.

nav.service.ts

import {EventEmitter} from 'angular2/core';
export class NavService {
  navchange: EventEmitter<number> = new EventEmitter();
  constructor() {}
  emitNavChangeEvent(number) {
    this.navchange.emit(number);
  }
  getNavChangeEmitter() {
    return this.navchange;
  }
}

components.ts

import {Component} from 'angular2/core';
import {NavService} from '../services/NavService';

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number = 0;
  subscription: any;
  constructor(private navService:NavService) {}
  ngOnInit() {
    this.subscription = this.navService.getNavChangeEmitter()
      .subscribe(item => this.selectedNavItem(item));
  }
  selectedNavItem(item: number) {
    this.item = item;
  }
  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
    <div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>
  `,
})
export class Navigation {
  item = 1;
  constructor(private navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this.navService.emitNavChangeEvent(item);
  }
}

Plunker

I received this debug message for a sillier reason than the other answers here: This is the error message received when you don't get enough sleep and reference a js file by using the syntax for a css file. As in,

<link rel='stylesheet' type='text/css' href='clearly_javascript.js'/>

rather than

<script src='clearly_javascript.js'></script>

Thought I'd put this up here because this is the first post that comes up when searching for the error message.

Best way is to update the serve script command in your package.json file. Just append --port 3000 like so:

"scripts": {
  "serve": "vue-cli-service serve --port 3000",
  "build": "vue-cli-service build",
  "inspect": "vue-cli-service inspect",
  "lint": "vue-cli-service lint"
},

Example for postgres:

string sql = "SELECT * FROM SomeTable WHERE id = ANY(@ids)"
var results = conn.Query(sql, new { ids = new[] { 1, 2, 3, 4, 5 }});

The Integer.toString(size) call converts into the char representation of your integer, i.e. the char '5'. The ASCII representation of that character is the value 65.

You need to parse the string back to an integer value first, e.g. by using Integer.parseInt, to get back the original int value.

As a bottom line, for a signed/unsigned conversion, it is best to leave String out of the picture and use bit manipulation as @JB suggests.

Setting async to false means the instructions following the ajax request will have to wait for the request to complete. Below is one case where one have to set async to false, for the code to work properly.

var phpData = (function get_php_data() {
  var php_data;
  $.ajax({
    url: "http://somesite/v1/api/get_php_data",
    async: false, 
    //very important: else php_data will be returned even before we get Json from the url
    dataType: 'json',
    success: function (json) {
      php_data = json;
    }
  });
  return php_data;
})();

Above example clearly explains the usage of async:false

By setting it to false, we have made sure that once the data is retreived from the url ,only after that return php_data; is called

To check if a path is an existing file:

os.path.isfile(path)

Return True if path is an existing regular file. This follows symbolic links, so both islink() and isfile() can be true for the same path.

Your compiler just tried to compile the file named foo.cc. Upon hitting line number line, the compiler finds:

#include "bar"

or

#include <bar>

The compiler then tries to find that file. For this, it uses a set of directories to look into, but within this set, there is no file bar. For an explanation of the difference between the versions of the include statement look here.

How to tell the compiler where to find it

g++ has an option -I. It lets you add include search paths to the command line. Imagine that your file bar is in a folder named frobnicate, relative to foo.cc (assume you are compiling from the directory where foo.cc is located):

g++ -Ifrobnicate foo.cc

You can add more include-paths; each you give is relative to the current directory. Microsoft's compiler has a correlating option /I that works in the same way, or in Visual Studio, the folders can be set in the Property Pages of the Project, under Configuration Properties->C/C++->General->Additional Include Directories.

Now imagine you have multiple version of bar in different folders, given:

// A/bar
#include<string>
std::string which() { return "A/bar"; }

// B/bar
#include<string>
std::string which() { return "B/bar"; }

// C/bar
#include<string>
std::string which() { return "C/bar"; }

// foo.cc
#include "bar"
#include <iostream>

int main () {
    std::cout << which() << std::endl;
}

The priority with #include "bar" is leftmost:

$ g++ -IA -IB -IC foo.cc
$ ./a.out
A/bar

As you see, when the compiler started looking through A/, B/ and C/, it stopped at the first or leftmost hit.

This is true of both forms, include <> and incude "".

Difference between #include <bar> and #include "bar"

Usually, the #include <xxx> makes it look into system folders first, the #include "xxx" makes it look into the current or custom folders first.

E.g.:

Imagine you have the following files in your project folder:

list
main.cc

with main.cc:

#include "list"
....

For this, your compiler will #include the file list in your project folder, because it currently compiles main.cc and there is that file list in the current folder.

But with main.cc:

#include <list>
....

and then g++ main.cc, your compiler will look into the system folders first, and because <list> is a standard header, it will #include the file named list that comes with your C++ platform as part of the standard library.

This is all a bit simplified, but should give you the basic idea.

Details on <>/""-priorities and -I

According to the gcc-documentation, the priority for include <> is, on a "normal Unix system", as follows:

 /usr/local/include
 libdir/gcc/target/version/include
 /usr/target/include
 /usr/include

For C++ programs, it will also look in /usr/include/c++/version, first. In the above, target is the canonical name of the system GCC was configured to compile code for; [...].

The documentation also states:

You can add to this list with the -Idir command line option. All the directories named by -I are searched, in left-to-right order, before the default directories. The only exception is when dir is already searched by default. In this case, the option is ignored and the search order for system directories remains unchanged.

To continue our #include<list> / #include"list" example (same code):

g++ -I. main.cc

and

#include<list>
int main () { std::list<int> l; }

and indeed, the -I. prioritizes the folder . over the system includes and we get a compiler error.

You have an array. A PHP array is basically a "list of things". Your array has one thing in it. That thing is a standard class. You need to either remove the thing from your array

$object = array_shift($array);
var_dump($object->id);

Or refer to the thing by its index in the array.

var_dump( $array[0]->id );

Or, if you're not sure how many things are in the array, loop over the array

foreach($array as $key=>$value)
{
    var_dump($value->id);
    var_dump($array[$key]->id);
}

If you are using Visual Studio then yes, you can do this.

The library builder tool that comes with Visual Studio allows you to join libraries together on the command line. I don't know of any way to do this in the visual editor though.

lib.exe /OUT:compositelib.lib  lib1.lib lib2.lib

I could be able to update the environment variable by using the following

string EnvPath = System.Environment.GetEnvironmentVariable("PATH", EnvironmentVariableTarget.Machine) ?? string.Empty;
if (!string.IsNullOrEmpty(EnvPath) && !EnvPath .EndsWith(";"))
    EnvPath = EnvPath + ';';
EnvPath = EnvPath + @"C:\Test";
Environment.SetEnvironmentVariable("PATH", EnvPath , EnvironmentVariableTarget.Machine);

Use System.DateTime.DaysInMonth, from code sample:

const int July = 7;
const int Feb = 2;

// daysInJuly gets 31.
int daysInJuly = System.DateTime.DaysInMonth(2001, July);

// daysInFeb gets 28 because the year 1998 was not a leap year.
int daysInFeb = System.DateTime.DaysInMonth(1998, Feb);

// daysInFebLeap gets 29 because the year 1996 was a leap year.
int daysInFebLeap = System.DateTime.DaysInMonth(1996, Feb);

Example 1:

This is how the and operator works.

x and y => if x is false, then x, else y

So in other words, since mylist1 is not False, the result of the expression is mylist2. (Only empty lists evaluate to False.)

Example 2:

The & operator is for a bitwise and, as you mention. Bitwise operations only work on numbers. The result of a & b is a number composed of 1s in bits that are 1 in both a and b. For example:

>>> 3 & 1
1

It's easier to see what's happening using a binary literal (same numbers as above):

>>> 0b0011 & 0b0001
0b0001

Bitwise operations are similar in concept to boolean (truth) operations, but they work only on bits.

So, given a couple statements about my car

1. My car is red
2. My car has wheels

The logical "and" of these two statements is:

(is my car red?) and (does car have wheels?) => logical true of false value

Both of which are true, for my car at least. So the value of the statement as a whole is logically true.

The bitwise "and" of these two statements is a little more nebulous:

(the numeric value of the statement 'my car is red') & (the numeric value of the statement 'my car has wheels') => number

If python knows how to convert the statements to numeric values, then it will do so and compute the bitwise-and of the two values. This may lead you to believe that & is interchangeable with and, but as with the above example they are different things. Also, for the objects that can't be converted, you'll just get a TypeError.

Example 3 and 4:

Numpy implements arithmetic operations for arrays:

Arithmetic and comparison operations on ndarrays are defined as element-wise operations, and generally yield ndarray objects as results.

But does not implement logical operations for arrays, because you can't overload logical operators in python. That's why example three doesn't work, but example four does.

So to answer your and vs & question: Use and.

The bitwise operations are used for examining the structure of a number (which bits are set, which bits aren't set). This kind of information is mostly used in low-level operating system interfaces (unix permission bits, for example). Most python programs won't need to know that.

The logical operations (and, or, not), however, are used all the time.

If you want to redirect HTTP to HTTPS and want to add www with each URL, use the htaccess below

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R=301,L] 

it will first redirect HTTP to HTTPS and then it will redirect to www.

Modals always load the content into an element on the page, which more often than not is a div. Think of this div as the iframe equivalent when it comes to jQuery UI Dialogs. Now it depends on your requirements whether you want static content that resides within the page or you want to fetch the content from some other location. You may use this code and see if it works for you:

    $("#dialog").dialog( "option", "title", titletext );
    $("#dialog").dialog( "option", "resizable", false );
    $("#dialog").dialog( "option", "buttons", {

There are, however, a few things which you should keep in mind. You will not be able to load remote URL's on your local system, you need to upload to a server if you want to load remote URL. Even then, you may only load URL's which belong to the same domain; e.g. if you upload this file to 'www.example.com' you may only access files hosted on 'www.example.com'. For loading external links this might help. All this information you will find in the link as suggested by @Robin.

If using a third party library is an option, there is jOOU (a spin off library from jOOQ), which offers wrapper types for unsigned integer numbers in Java. That's not exactly the same thing as having primitive type (and thus byte code) support for unsigned types, but perhaps it's still good enough for your use-case.

import static org.joou.Unsigned.*;

// and then...
UByte    b = ubyte(1);
UShort   s = ushort(1);
UInteger i = uint(1);
ULong    l = ulong(1);

All of these types extend java.lang.Number and can be converted into higher-order primitive types and BigInteger.

(Disclaimer: I work for the company behind these libraries)

you never change the value of rng so it always points to the initial cell

copy the Set rng = rng.Offset(1, 0) to a new line before loop

also, your InStr test will always fail
True is -1, but the return from InStr will be greater than 0 when the string is found. change the test to remove = True

new code:

Sub IfTest()
 'This should split the information in a table up into cells
 Dim Splitter() As String
 Dim LenValue As Integer     'Gives the number of characters in date string
 Dim LeftValue As Integer    'One less than the LenValue to drop the ")"
 Dim rng As Range, cell As Range
 Set rng = ActiveCell

Do While ActiveCell.Value <> Empty
    If InStr(rng, "%") Then
        ActiveCell.Offset(0, 0).Select
        Splitter = Split(ActiveCell.Value, "% Change")
        ActiveCell.Offset(0, 10).Select
        ActiveCell.Value = Splitter(1)
        ActiveCell.Offset(0, -1).Select
        ActiveCell.Value = "% Change"
        ActiveCell.Offset(1, -9).Select
    Else
        ActiveCell.Offset(0, 0).Select
        Splitter = Split(ActiveCell.Value, "(")
        ActiveCell.Offset(0, 9).Select
        ActiveCell.Value = Splitter(0)
        ActiveCell.Offset(0, 1).Select
        LenValue = Len(Splitter(1))
        LeftValue = LenValue - 1
        ActiveCell.Value = Left(Splitter(1), LeftValue)
        ActiveCell.Offset(1, -10).Select
    End If
Set rng = rng.Offset(1, 0)
Loop

End Sub

Place the below line in your .htaccess file and replace the file name as you wish

There is one possible pitfall with using textBoxName.Text = string.Empty; and that is if you are using Text binding for your TextBox (i.e. <TextBox Text="{Binding Path=Description}"></TextBox>). In this case, setting an empty string will actually override and break your binding.

To prevent this behavior you have to use the Clear method:

textBoxName.Clear();

This way the TextBox will be cleared, but the binding will be kept intact.

This problem was caused by the li display attribute being set to block in a parent class. Overriding with list-item solved the problem.

Rather than referring to the literal name of the class, inside an instance method you can just call self.class.whatever.

class Foo
    def self.some_class_method
        puts self
    end

    def some_instance_method
        self.class.some_class_method
    end
end

print "Class method: "
Foo.some_class_method

print "Instance method: "
Foo.new.some_instance_method

Outputs:

Class method: Foo
Instance method: Foo

If you just need to print present working directory then you can follow this.

$ vim test

#!/bin/bash
pwd
:wq to save the test file.

Give execute permission:

chmod u+x test

Then execute the script by ./test then you can see the present working directory.

I don't see an obvious problem with the above.

It's possible your ldap.conf is being overridden, but the command-line options will take precedence, ldapsearch will ignore BINDDN in the main ldap.conf, so the only parameter that could be wrong is the URI. (The order is ETCDIR/ldap.conf then ~/ldaprc or ~/.ldaprc and then ldaprc in the current directory, though there environment variables which can influence this too, see man ldapconf.)

Try an explicit URI:

ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base -H ldap://localhost

or prevent defaults with:

LDAPNOINIT=1 ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

If that doesn't work, then some troubleshooting (you'll probably need the full path to the slapd binary for these):

• make sure your slapd.conf is being used and is correct (as root)

  slapd -T test -f slapd.conf -d 65535

  You may have a left-over or default slapd.d configuration directory which takes preference over your slapd.conf (unless you specify your config explicitly with -f, slapd.conf is officially deprecated in OpenLDAP-2.4). If you don't get several pages of output then your binaries were built without debug support.

• stop OpenLDAP, then manually start slapd in a separate terminal/console with debug enabled (as root, ^C to quit)

  slapd -h ldap://localhost -d 481

  then retry the search and see if you can spot the problem (there will be a lot of schema noise in the start of the output unfortunately). (Note: running slapd without the -u/-g options can change file ownerships which can cause problems, you should usually use those options, probably -u ldap -g ldap )

• if debug is enabled, then try also

  ldapsearch -v -d 63 -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

create_function did not work for me inside a class. I had to use call_user_func.

<?php

class Dispatcher {
    //Added explicit callback declaration.
    var $callback;

    public function Dispatcher( $callback ){
         $this->callback = $callback;
    }

    public function asynchronous_method(){
       //do asynch stuff, like fwrite...then, fire callback.
       if ( isset( $this->callback ) ) {
            if (function_exists( $this->callback )) call_user_func( $this->callback, "File done!" );
        }
    }

}

Then, to use:

<?php 
include_once('Dispatcher.php');
$d = new Dispatcher( 'do_callback' );
$d->asynchronous_method();

function do_callback( $data ){
   print 'Data is: ' .  $data .  "\n";

[Edit] Added a missing parenthesis. Also, added the callback declaration, I prefer it that way.

No need to changes anything on DB level, just you have to changes in SQL Query it will work.

Example -

"SELECT * FROM <TABLE> where userId = '" + iv_userId + "' AND password = BINARY '" + iv_password + "'";

Binary keyword will make case sensitive.

Another way to achieve this in Apache is by putting the following lines in .htaccess in the root folder of your website (or in Apache's config files).

BrowserMatch "MSIE" isIE
BrowserMatch "Trident" isIE
Header set X-UA-Compatible "IE=edge" env=isIE

This requires that you have the mod_headers and mod_setenvif modules enabled.

The extra HTTP header only gets sent to IE browsers, and none of the others.

You have invoked Ant with the verbose (-v) mode but the default buildfile build.xml does not exist. Nor have you specified any other buildfile for it to use.

I would say your Ant installation is fine.

Obviously, of the two methods you mention number 1 is more efficient, since it only needs to go through the list once, while with method number 2 the list has to be traversed two times (first to find the elements to remove, and them to remove them).

Actually, removing a list of elements from another list is likely an algorithm that's worse than O(n) so method 2 is even worse.

The iterator method:

List data = ...;

for (Iterator i = data.iterator(); i.hasNext(); ) {
    Object element = i.next();

    if (!(...)) {
        i.remove();
    }
}

Create this class:

public class StdOutErrLog {

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

public static void tieSystemOutAndErrToLog() {
    System.setOut(createLoggingProxy(System.out));
    System.setErr(createLoggingProxy(System.err));
}

public static PrintStream createLoggingProxy(final PrintStream realPrintStream) {
    return new PrintStream(realPrintStream) {
        public void print(final String string) {
            logger.info(string);
        }
        public void println(final String string) {
            logger.info(string);
        }
    };
}
}

Call this in your code

StdOutErrLog.tieSystemOutAndErrToLog();

Yet another method to solve: updating registry. In my case I could not alter GPO, and -UseBasicParsing breaks parts of the access to the website. Also I had a service user without log in permissions, so I could not log in as the user and run the GUI.
To fix,

1. log in as a normal user, run IE setup.
2. Then export this registry key: HKEY_USERS\S-1-5-21-....\SOFTWARE\Microsoft\Internet Explorer
3. In the .reg file that is saved, replace the user sid with the service account sid
4. Import the .reg file

In the file

Optionally, select Auto Import on the next screen to automatically import new dependencies.

The variable %0 in a batch script is set to the name of the executing batch file.

The ~dp special syntax between the % and the 0 basically says to expand the variable %0 to show the drive letter and path, which gives you the current directory containing the batch file!

Here are a few ways to create a list with N of continuous natural numbers starting from 1.

1 range:

def numbers(n): 
    return range(1, n+1);

2 List Comprehensions:

def numbers(n):
    return [i for i in range(1, n+1)]

You may want to look into the method xrange and the concepts of generators, those are fun in python. Good luck with your Learning!

This is similar to some of the other answers, but is compact and avoids the conversion to dictionary if you already have a list.

Given a ComboBox "combobox" on a windows form and a class SomeClass with the string type property Name,

List<SomeClass> list = new List<SomeClass>();

combobox.DisplayMember = "Name";
combobox.DataSource = list;

Which means that the SelectedItem is a SomeClass object from list, and each item in combobox will be displayed using its name.

Swift 4.2+ String to Double

You should use the new type initializers to convert between String and numeric types (Double, Float, Int). It'll return an Optional type (Double?) which will have the correct value or nil if the String was not a number.

Note: The NSString doubleValue property is not recommended because it returns 0 if the value cannot be converted (i.e.: bad user input).

let lessPrecisePI = Float("3.14")

let morePrecisePI = Double("3.1415926536")
let invalidNumber = Float("alphabet") // nil, not a valid number

Unwrap the values to use them using if/let

if let cost = Double(textField.text!) {
    print("The user entered a value price of \(cost)")
} else {
    print("Not a valid number: \(textField.text!)")
}

You can convert formatted numbers and currency using the NumberFormatter class.

let formatter = NumberFormatter()
formatter.locale = Locale.current // USA: Locale(identifier: "en_US")
formatter.numberStyle = .decimal
let number = formatter.number(from: "9,999.99")

Currency formats

let usLocale = Locale(identifier: "en_US")
let frenchLocale = Locale(identifier: "fr_FR")
let germanLocale = Locale(identifier: "de_DE")
let englishUKLocale = Locale(identifier: "en_GB") // United Kingdom
formatter.numberStyle = .currency

formatter.locale = usLocale
let usCurrency = formatter.number(from: "$9,999.99")

formatter.locale = frenchLocale
let frenchCurrency = formatter.number(from: "9999,99€")
// Note: "9 999,99€" fails with grouping separator
// Note: "9999,99 €" fails with a space before the €

formatter.locale = germanLocale
let germanCurrency = formatter.number(from: "9999,99€")
// Note: "9.999,99€" fails with grouping separator

formatter.locale = englishUKLocale
let englishUKCurrency = formatter.number(from: "£9,999.99")

With Spark 2.4+, if you want to load a csv from a local directory, then you can use 2 sessions and load that into hive. The first session should be created with master() config as "local[*]" and the second session with "yarn" and Hive enabled.

The below one worked for me.

import org.apache.log4j.{Level, Logger}
import org.apache.spark._
import org.apache.spark.rdd._
import org.apache.spark.sql._

object testCSV { 

  def main(args: Array[String]) {
    Logger.getLogger("org").setLevel(Level.ERROR)
    val spark_local = SparkSession.builder().appName("CSV local files reader").master("local[*]").getOrCreate()

    import spark_local.implicits._
    spark_local.sql("SET").show(100,false)
    val local_path="/tmp/data/spend_diversity.csv"  // Local file
    val df_local = spark_local.read.format("csv").option("inferSchema","true").load("file://"+local_path) // "file://" is mandatory
    df_local.show(false)

    val spark = SparkSession.builder().appName("CSV HDFS").config("spark.sql.warehouse.dir", "/apps/hive/warehouse").enableHiveSupport().getOrCreate()

    import spark.implicits._
    spark.sql("SET").show(100,false)
    val df = df_local
    df.createOrReplaceTempView("lcsv")
    spark.sql(" drop table if exists work.local_csv ")
    spark.sql(" create table work.local_csv as select * from lcsv ")

   }

When ran with spark2-submit --master "yarn" --conf spark.ui.enabled=false testCSV.jar it went fine and created the table in hive.

Here's a LINQ solution which is virtually the same but more scalable:

new[] { "a", "b", "c" }.Any(c => s.Contains(c))

multi-map

This is really helpful if you want to create a multimap without resorting to the Google Guava library for its implementation of MultiMap.

For example, suppose you want to store a list of students who enrolled for a particular subject.

The normal solution for this using JDK library is:

Map<String,List<String>> studentListSubjectWise = new TreeMap<>();
List<String>lis = studentListSubjectWise.get("a");
if(lis == null) {
    lis = new ArrayList<>();
}
lis.add("John");

//continue....

Since it have some boilerplate code, people tend to use Guava Mutltimap.

Using Map.computeIfAbsent, we can write in a single line without guava Multimap as follows.

studentListSubjectWise.computeIfAbsent("a", (x -> new ArrayList<>())).add("John");

You are using an immutable list. The operations on the List return a new List. The old List remains unchanged. This can be very useful if another class / method holds a reference to the original collection and is relying on it remaining unchanged. You can either use different named vals as in

val myList1 = 1.0 :: 5.5 :: Nil 
val myList2 = 2.2 :: 3.7 :: mylist1

or use a var as in

var myList = 1.0 :: 5.5 :: Nil 
myList :::= List(2.2, 3.7)

This is equivalent syntax for:

myList = myList.:::(List(2.2, 3.7))

Or you could use one of the mutable collections such as

val myList = scala.collection.mutable.MutableList(1.0, 5.5)
myList.++=(List(2.2, 3.7))

Not to be confused with the following that does not modify the original mutable List, but returns a new value:

myList.++:(List(2.2, 3.7))

However you should only use mutable collections in performance critical code. Immutable collections are much easier to reason about and use. One big advantage is that immutable List and scala.collection.immutable.Vector are Covariant. Don't worry if that doesn't mean anything to you yet. The advantage of it is you can use it without fully understanding it. Hence the collection you were using by default is actually scala.collection.immutable.List its just imported for you automatically.

I tend to use List as my default collection. From 2.12.6 Seq defaults to immutable Seq prior to this it defaulted to immutable.

I use this free program to synchronize local files and directories: https://github.com/Fitus/Zaloha.sh. The repository contains a simple demo as well.

The good point: It is a bash shell script (one file only). Not a black box like other programs. Documentation is there as well. Also, with some technical talents, you can "bend" and "integrate" it to create the final solution you like.

Remove last 3 characters of a string

var str = '1437203995000';
str = str.substring(0, str.length-3);
// '1437203995'

Remove last 3 digits of a number

var a = 1437203995000;
a = (a-(a%1000))/1000;
// a = 1437203995

Apparently the files were added in remote repository, no matter what was the content of .gitignore file in the origin.

As the files exist in the remote repository, git has to pull them to your local work tree as well and therefore complains that the files already exist.

.gitignore is used only for scanning for the newly added files, it doesn't have anything to do with the files which were already added.

So the solution is to remove the files in your work tree and pull the latest version. Or the long-term solution is to remove the files from the repository if they were added by mistake.

A simple example to remove files from the remote branch is to

$git checkout <brachWithFiles>
$git rm -r *.extension
$git commit -m "fixin...."
$git push

Then you can try the $git merge again

Say you have static fields and methods inside a class called MyClass inside a package called myPackage and you want to access them directly by typing myStaticField or myStaticMethod without typing each time MyClass.myStaticField or MyClass.myStaticMethod.

Note : you need to do an import myPackage.MyClass or myPackage.* for accessing the other resources

There is no easy way to get all DNS records for a domain in one instance. You can only view certain records for example, if you wanna see an A record for a certain domain you can use the command: dig a(type of record) domain.com. This is the same for all the other type of records you wanna see for that domain.

If your not familiar with the command line interface, you can also use a site like mxtoolbox.com. Wich is very handy tool for getting records of a domain.

I hope this answers your question.

Yes, there is a better way: You can use the $parse service in your directive to evaluate an expression in the context of the parent scope while binding certain identifiers in the expression to values visible only inside your directive:

$parse(attributes.callback)(scope.$parent, { arg2: yourSecondArgument });

Add this line to the link function of the directive where you can access the directive's attributes.

Your callback attribute may then be set like callback = "callback(item.id, arg2)" because arg2 is bound to yourSecondArgument by the $parse service inside the directive. Directives like ng-click let you access the click event via the $event identifier inside the expression passed to the directive by using exactly this mechanism.

Note that you do not have to make callback a member of your isolated scope with this solution.

Documentation for parseDouble() says "Returns a new double initialized to the value represented by the specified String, as performed by the valueOf method of class Double.", so they should be identical.

Combine the mousemove and window.onbeforeunload event :- I used for set TimeOut for Audit Table.

 $(document).ready(function () {
 var checkCloseX = 0;
        $(document).mousemove(function (e) {
            if (e.pageY <= 5) {
                checkCloseX = 1;
            }
            else { checkCloseX = 0; }
        });

        window.onbeforeunload = function (event) {
            if (event) {
                if (checkCloseX == 1) {

                    //alert('1111');
                    $.ajax({
                        type: "GET",
                        url: "Account/SetAuditHeaderTimeOut",
                        dataType: "json",
                        success: function (result) {
                            if (result != null) {
                            }
                        }
                    });
                }
            }
        };
  });

What you want is called an associative array. In python these are called dictionaries.

Dictionaries are sometimes found in other languages as “associative memories” or “associative arrays”. Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys.

myDict = {}
myDict["john"] = "johns value"
myDict["jeff"] = "jeffs value"

Alternative way to create the above dict:

myDict = {"john": "johns value", "jeff": "jeffs value"}

Accessing values:

print(myDict["jeff"]) # => "jeffs value"

Getting the keys (in Python v2):

print(myDict.keys()) # => ["john", "jeff"]

In Python 3, you'll get a dict_keys, which is a view and a bit more efficient (see views docs and PEP 3106 for details).

print(myDict.keys()) # => dict_keys(['john', 'jeff']) 

If you want to learn about python dictionary internals, I recommend this ~25 min video presentation: https://www.youtube.com/watch?v=C4Kc8xzcA68. It's called the "The Mighty Dictionary".

It can also be used as below:

from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)

record = int(input("Enter the student record need to add :"))

stud_data={}

for i in range(0,record):
    Name = input("Enter the student name :").split()
    Age = input("Enter the {} age :".format(Name))
    Grade = input("Enter the {} grade :".format(Name)).split()
    Nam_key =  Name[0]
    Age_value = Age[0]
    Grade_value = Grade[0]
    stud_data[Nam_key] = {Age_value,Grade_value}

print(stud_data)

You have to bind your methods with 'this' (default object). So whatever your function may be just bind that in the constructor.

constructor(props) {
    super(props);
    this.state = { checked:false };

    this.handleChecked = this.handleChecked.bind(this);
}

handleChecked(){
    this.setState({
        checked: !(this.state.checked)
    })
}

render(){
    var msg;

    if(this.state.checked){
        msg = 'checked'
    }
    else{
        msg = 'not checked'
    }

    return (
        <div>               
            <input type='checkbox' defaultChecked = {this.state.checked} onChange = {this.handleChecked} />
            <h3>This is {msg}</h3>
        </div>
    );

Have you looked into rasdial?

Just incase anyone wanted to do this and finds this in the future, you can use rasdial.exe from command prompt to connect to a VPN network

ie rasdial "VPN NETWORK NAME" "Username" *

it will then prompt for a password, else you can use "username" "password", this is however less secure

I get the same error in WP when I use php ver 7.1.6 - just take your php version back to 7.0.20 and the error will disappear.

This will go through the source directory, create any directories that do not already exist in destination directory, and move files from source to the destination directory:

import os
import shutil

root_src_dir = 'Src Directory\\'
root_dst_dir = 'Dst Directory\\'

for src_dir, dirs, files in os.walk(root_src_dir):
    dst_dir = src_dir.replace(root_src_dir, root_dst_dir, 1)
    if not os.path.exists(dst_dir):
        os.makedirs(dst_dir)
    for file_ in files:
        src_file = os.path.join(src_dir, file_)
        dst_file = os.path.join(dst_dir, file_)
        if os.path.exists(dst_file):
            # in case of the src and dst are the same file
            if os.path.samefile(src_file, dst_file):
                continue
            os.remove(dst_file)
        shutil.move(src_file, dst_dir)

Any pre-existing files will be removed first (via os.remove) before being replace by the corresponding source file. Any files or directories that already exist in the destination but not in the source will remain untouched.

you can unpack your tuples and get only the first element using a list comprehension:

l = [(1, u'abc'), (2, u'def')]
[f for f, *_ in l]

output:

[1, 2]

this will work no matter how many elements you have in a tuple:

l = [(1, u'abc'), (2, u'def', 2, 4, 5, 6, 7)]
[f for f, *_ in l]

output:

[1, 2]

You should be aware that you should avoid file I/O from within Linux kernel when possible. The main idea is to go "one level deeper" and call VFS level functions instead of the syscall handler directly:

Includes:

#include <linux/fs.h>
#include <asm/segment.h>
#include <asm/uaccess.h>
#include <linux/buffer_head.h>

Opening a file (similar to open):

struct file *file_open(const char *path, int flags, int rights) 
{
    struct file *filp = NULL;
    mm_segment_t oldfs;
    int err = 0;

    oldfs = get_fs();
    set_fs(get_ds());
    filp = filp_open(path, flags, rights);
    set_fs(oldfs);
    if (IS_ERR(filp)) {
        err = PTR_ERR(filp);
        return NULL;
    }
    return filp;
}

Close a file (similar to close):

void file_close(struct file *file) 
{
    filp_close(file, NULL);
}

Reading data from a file (similar to pread):

int file_read(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size) 
{
    mm_segment_t oldfs;
    int ret;

    oldfs = get_fs();
    set_fs(get_ds());

    ret = vfs_read(file, data, size, &offset);

    set_fs(oldfs);
    return ret;
}   

Writing data to a file (similar to pwrite):

int file_write(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size) 
{
    mm_segment_t oldfs;
    int ret;

    oldfs = get_fs();
    set_fs(get_ds());

    ret = vfs_write(file, data, size, &offset);

    set_fs(oldfs);
    return ret;
}

Syncing changes a file (similar to fsync):

int file_sync(struct file *file) 
{
    vfs_fsync(file, 0);
    return 0;
}

[Edit] Originally, I proposed using file_fsync, which is gone in newer kernel versions. Thanks to the poor guy suggesting the change, but whose change was rejected. The edit was rejected before I could review it.

The docs describe the attributes available on the request. In most common cases request.data will be empty because it's used as a fallback:

request.data Contains the incoming request data as string in case it came with a mimetype Flask does not handle.

• request.args: the key/value pairs in the URL query string
• request.form: the key/value pairs in the body, from a HTML post form, or JavaScript request that isn't JSON encoded
• request.files: the files in the body, which Flask keeps separate from form. HTML forms must use enctype=multipart/form-data or files will not be uploaded.
• request.values: combined args and form, preferring args if keys overlap
• request.json: parsed JSON data. The request must have the application/json content type, or use request.get_json(force=True) to ignore the content type.

All of these are MultiDict instances (except for json). You can access values using:

• request.form['name']: use indexing if you know the key exists
• request.form.get('name'): use get if the key might not exist
• request.form.getlist('name'): use getlist if the key is sent multiple times and you want a list of values. get only returns the first value.

I had a hell of a time finding this option in SQL Management Studio 2012, but I finally found it. The option is hiding in the Advanced button in the screen below.

I always assumed this contained just assumed advanced options for File generation, since that's what it's next to, but it turns out someone at MS is just really bad at UI design in this case. HTH somebody who comes to this thread like I did.

I'd guess that your iMac isn't 64-bit (you state in another thread it is an original white intel iMac). Try the 32-bit version of MySQL–it should install directly over the 64-bit version, I think.

Have you tried JQuery? Vanilla javascript can be tough. Try using this:

$('.container-element').add('<div>Insert Div Content</div>');

.container-element is a JQuery selector that marks the element with the class "container-element" (presumably the parent element in which you want to insert your divs). Then the add() function inserts HTML into the container-element.

You can do like this.

<input type="button" value="mybutton1" onclick="dosomething(this)">

function dosomething(element){
    alert("value is "+element.value); //you can print any value like id,class,value,innerHTML etc.
};

Simpler than the accepted answer is this:

public static Bitmap cropAtRect(this Bitmap b, Rectangle r)
{
    Bitmap nb = new Bitmap(r.Width, r.Height);
    using (Graphics g = Graphics.FromImage(nb))
    {
        g.DrawImage(b, -r.X, -r.Y);
        return nb;
    }
}

and it avoids the "Out of memory" exception risk of the simplest answer.

Note that Bitmap and Graphics are IDisposable hence the using clauses.

EDIT: I find this is fine with PNGs saved by Bitmap.Save or Paint.exe, but fails with PNGs saved by e.g. Paint Shop Pro 6 - the content is displaced. Addition of GraphicsUnit.Pixel gives a different wrong result. Perhaps just these failing PNGs are faulty.

Let's break down the full URL that a client would type into their address bar to reach your servlet:

http://www.example.com:80/awesome-application/path/to/servlet/path/info?a=1&b=2#boo

The parts are:

1. scheme: http
2. hostname: www.example.com
3. port: 80
4. context path: awesome-application
5. servlet path: path/to/servlet
6. path info: path/info
7. query: a=1&b=2
8. fragment: boo

The request URI (returned by getRequestURI) corresponds to parts 4, 5 and 6.

(incidentally, even though you're not asking for this, the method getRequestURL would give you parts 1, 2, 3, 4, 5 and 6).

Now:

• part 4 (the context path) is used to select your particular application out of many other applications that may be running in the server
• part 5 (the servlet path) is used to select a particular servlet out of many other servlets that may be bundled in your application's WAR
• part 6 (the path info) is interpreted by your servlet's logic (e.g. it may point to some resource controlled by your servlet).
• part 7 (the query) is also made available to your servlet using getQueryString
• part 8 (the fragment) is not even sent to the server and is relevant and known only to the client

The following always holds (except for URL encoding differences):

requestURI = contextPath + servletPath + pathInfo

The following example from the Servlet 3.0 specification is very helpful:

Note: image follows, I don't have the time to recreate in HTML:

If you want to see your files in Explorer tree...

when you click anywhere in the explorer tree and start typing something on the keyboard, the search keyword appears in the top right corner of the screen : ("module.ts")

And when you hover over the keyword with the mouse cursor, you can click on "Enable Filter on Type" to filter tree with your search !

Maybe you can try something like this:

Using a directive

directive('watchChange', function() {
    return {
        scope: {
            onchange: '&watchChange'
        },
        link: function(scope, element, attrs) {
            element.on('input', function() {
                scope.onchange();
            });
        }
    };
});

JPG doesn't support transparency

You have to open database connection, not workbench file with schema. It looks a bit wierd, but it makes sense when you realize what you are editing.

So, go to home tab, double click database connection (create it if you don't have it yet) and have fun.

If you are using CORS middleware and you want to send withCredential boolean true, you can configure CORS like this:

var cors = require('cors');    
app.use(cors({credentials: true, origin: 'http://localhost:3000'}));

With Postgres, you may use

select * from users where active

or

select * from users where active = 't'

If you want to use integer value, you have to consider it as a string. You can't use integer value.

select * from users where active = 1   -- Does not work

select * from users where active = '1' -- Works 

The same way -- e.g. if you have an 8-bit char, 7 bits can be used for magnitude and 1 for sign. So an unsigned char might range from 0 to 255, whilst a signed char might range from -128 to 127 (for example).

To create a copy of the crop we want, we can do the following,

// Read img
cv::Mat img = cv::imread("imgFileName");
cv::Mat croppedImg;

// This line picks out the rectangle from the image
// and copies to a new Mat
img(cv::Rect(xMin,yMin,xMax-xMin,yMax-yMin)).copyTo(croppedImg);

// Display diff
cv::imshow( "Original Image",  img );
cv::imshow( "Cropped Image",  croppedImg);
cv::waitKey();

One option is to put the character literally in your script, e.g.:

const omega = 'O';

This requires that you let the browser know the correct source encoding, see Unicode in JavaScript

However, if you can't or don't want to do this (e.g. because the character is too exotic and can't be expected to be available in the code editor font), the safest option may be to use new-style string escape or String.fromCodePoint:

const omega = '\u{3a9}';

// or:

const omega = String.fromCodePoint(0x3a9);

This is not restricted to UTF-16 but works for all unicode code points. In comparison, the other approaches mentioned here have the following downsides:

• HTML escapes (const omega = '&#937';): only work when rendered unescaped in an HTML element
• old style string escapes (const omega = '\u03A9';): restricted to UTF-16
• String.fromCharCode: restricted to UTF-16

Use an object, as people are saying. However, note that you can not have integer keys. JavaScript will convert the integer to a string. The following outputs 20, not undefined:

var test = {}
test[2300] = 20;
console.log(test["2300"]);

Encapsulation:

Hiding something, sort of like medicine capsule. We don't know what is in the capsule, we just take it. Same as in programming - we just hide some special code of method or property and it only gives output, same as capsule. In short, encapsulation hides data.

Abstraction:

Abstraction means hiding logic or implementation. For example, we take tablets and see their color and but don't know what is the purpose of this and how it works with the body.

So I used to use a for loop for iterating through the dictionary as well, but one thing I've found that works much faster is to convert to a panel and then to a dataframe. Say you have a dictionary d

import pandas as pd
d
{'RAY Index': {datetime.date(2014, 11, 3): {'PX_LAST': 1199.46,
'PX_OPEN': 1200.14},
datetime.date(2014, 11, 4): {'PX_LAST': 1195.323, 'PX_OPEN': 1197.69},
datetime.date(2014, 11, 5): {'PX_LAST': 1200.936, 'PX_OPEN': 1195.32},
datetime.date(2014, 11, 6): {'PX_LAST': 1206.061, 'PX_OPEN': 1200.62}},
'SPX Index': {datetime.date(2014, 11, 3): {'PX_LAST': 2017.81,
'PX_OPEN': 2018.21},
datetime.date(2014, 11, 4): {'PX_LAST': 2012.1, 'PX_OPEN': 2015.81},
datetime.date(2014, 11, 5): {'PX_LAST': 2023.57, 'PX_OPEN': 2015.29},
datetime.date(2014, 11, 6): {'PX_LAST': 2031.21, 'PX_OPEN': 2023.33}}}

The command

pd.Panel(d)
<class 'pandas.core.panel.Panel'>
Dimensions: 2 (items) x 2 (major_axis) x 4 (minor_axis)
Items axis: RAY Index to SPX Index
Major_axis axis: PX_LAST to PX_OPEN
Minor_axis axis: 2014-11-03 to 2014-11-06

where pd.Panel(d)[item] yields a dataframe

pd.Panel(d)['SPX Index']
2014-11-03  2014-11-04  2014-11-05 2014-11-06
PX_LAST 2017.81 2012.10 2023.57 2031.21
PX_OPEN 2018.21 2015.81 2015.29 2023.33

You can then hit the command to_frame() to turn it into a dataframe. I use reset_index as well to turn the major and minor axis into columns rather than have them as indices.

pd.Panel(d).to_frame().reset_index()
major   minor      RAY Index    SPX Index
PX_LAST 2014-11-03  1199.460    2017.81
PX_LAST 2014-11-04  1195.323    2012.10
PX_LAST 2014-11-05  1200.936    2023.57
PX_LAST 2014-11-06  1206.061    2031.21
PX_OPEN 2014-11-03  1200.140    2018.21
PX_OPEN 2014-11-04  1197.690    2015.81
PX_OPEN 2014-11-05  1195.320    2015.29
PX_OPEN 2014-11-06  1200.620    2023.33

Finally, if you don't like the way the frame looks you can use the transpose function of panel to change the appearance before calling to_frame() see documentation here http://pandas.pydata.org/pandas-docs/dev/generated/pandas.Panel.transpose.html

Just as an example

pd.Panel(d).transpose(2,0,1).to_frame().reset_index()
major        minor  2014-11-03  2014-11-04  2014-11-05  2014-11-06
RAY Index   PX_LAST 1199.46    1195.323     1200.936    1206.061
RAY Index   PX_OPEN 1200.14    1197.690     1195.320    1200.620
SPX Index   PX_LAST 2017.81    2012.100     2023.570    2031.210
SPX Index   PX_OPEN 2018.21    2015.810     2015.290    2023.330

Hope this helps.

Try this instead:

echo "This is 02G05 a test string 20-Jul-2012" | sed 's/.* \([0-9]\+G[0-9]\+\) .*/\1/'

But note, if there is two pattern on one line, it will prints the 2nd.

In 5.2.47 (at least on mac), go the location of the preferences is: MySQLWorkbench->Preferences->SQL Editor

Then you'll see both:

DBMS connection keep-alive interval (in seconds): DBMS connection read time out (in seconds):

The latter is where you'll want to up the limit from 600 to something a bit more.

Dragging an object and placing in a different location is part of the standard of HTML5. All the objects can be draggable. But the Specifications of below web browser should be followed. API Chrome Internet Explorer Firefox Safari Opera Version 4.0 9.0 3.5 6.0 12.0

You can find example from below: https://www.w3schools.com/html/tryit.asp?filename=tryhtml5_draganddrop2

Since you've already stashed your changes, all you need is this one-liner:

• git stash branch <branchname> [<stash>]

From the docs (https://www.kernel.org/pub/software/scm/git/docs/git-stash.html):

Creates and checks out a new branch named <branchname> starting from the commit at which the <stash> was originally created, applies the changes recorded in <stash> to the new working tree and index. If that succeeds, and <stash> is a reference of the form stash@{<revision>}, it then drops the <stash>. When no <stash> is given, applies the latest one.

This is useful if the branch on which you ran git stash save has changed enough that git stash apply fails due to conflicts. Since the stash is applied on top of the commit that was HEAD at the time git stash was run, it restores the originally stashed state with no conflicts.

Really depends on your requirement, although lately I have seen a trend for classes with at least one bare constructor defined.

The upside of posting your parameters in via constructor is that you know those values can be relied on after instantiation. The downside is that you'll need to put more work in with any library that expects to be able to create objects with a bare constructor.

My personal preference is to go with a bare constructor and set any properties as part of the declaration.

Person p=new Person()
{
   Name = "Han Solo",
   Age = 39
};

This gets around the "class lacks bare constructor" problem, plus reduces maintenance ( I can set more things without changing the constructor ).

The below worked for me:

for col in df:
    if 'Unnamed' in col:
        #del df[col]
        print col
        try:
            df.drop(col, axis=1, inplace=True)
        except Exception:
            pass

I've set up EGit in Eclipse for a few of my projects and find that its a lot easier, faster to use a command line interface versus having to drill down menus and click around windows.

I would prefer something like a command line view within Eclipse to do all the Git duties.

Reference the System.Web dll in your model and use System.Web.Caching.Cache

    public string[] GetNames()
    {
      string[] names = Cache["names"] as string[];
      if(names == null) //not in cache
      {
        names = DB.GetNames();
        Cache["names"] = names;
      }
      return names;
    }

A bit simplified but I guess that would work. This is not MVC specific and I have always used this method for caching data.

The express.static middleware is separate from res.sendFile, so initializing it with an absolute path to your public directory won't do anything to res.sendFile. You need to use an absolute path directly with res.sendFile. There are two simple ways to do it:

1. res.sendFile(path.join(__dirname, '../public', 'index1.html'));
2. res.sendFile('index1.html', { root: path.join(__dirname, '../public') });

Note: __dirname returns the directory that the currently executing script is in. In your case, it looks like server.js is in app/. So, to get to public, you'll need back out one level first: ../public/index1.html.

Note: path is a built-in module that needs to be required for the above code to work: var path = require('path');

Complementing the @DanielLew answer, to get the values of the parameteres you have to do this:

URI example: myapp://path/to/what/i/want?keyOne=valueOne&keyTwo=valueTwo

in your activity:

Intent intent = getIntent();
if (Intent.ACTION_VIEW.equals(intent.getAction())) {
  Uri uri = intent.getData();
  String valueOne = uri.getQueryParameter("keyOne");
  String valueTwo = uri.getQueryParameter("keyTwo");
}

You need nunique:

df = df.groupby('domain')['ID'].nunique()

print (df)
domain
'facebook.com'    1
'google.com'      1
'twitter.com'     2
'vk.com'          3
Name: ID, dtype: int64

If you need to strip ' characters:

df = df.ID.groupby([df.domain.str.strip("'")]).nunique()
print (df)
domain
facebook.com    1
google.com      1
twitter.com     2
vk.com          3
Name: ID, dtype: int64

Or as Jon Clements commented:

df.groupby(df.domain.str.strip("'"))['ID'].nunique()

You can retain the column name like this:

df = df.groupby(by='domain', as_index=False).agg({'ID': pd.Series.nunique})
print(df)
    domain  ID
0       fb   1
1      ggl   1
2  twitter   2
3       vk   3

The difference is that nunique() returns a Series and agg() returns a DataFrame.

Usually when you get this problem, it happens because a script is trying to reference an element that doesn't exist yet while the page is loading.

As richie mentioned: "The HTML parser will parse the HTML content from top to bottom..."

So you can add your JavaScript references to the bottom of the HTML file. This will not only improve performance; it will also ensure that all elements referenced in your script files have already been loaded by the HTML parser.

So you could have something like this:

<html>
    <head>
        <!--  Style sheet references and CSS definitions -->
    </head>
    <body>
        <!-- HTML markup and other page content -->

        <!-- JavaScript references. You could include jQuery here as well and do all your scripting here. -->
    </body>
</html>

Set the name in the form to check_list[] and you will be able to access all the checkboxes as an array($_POST['check_list'][]).

Here's a little sample as requested:

<form action="test.php" method="post">
    <input type="checkbox" name="check_list[]" value="value 1">
    <input type="checkbox" name="check_list[]" value="value 2">
    <input type="checkbox" name="check_list[]" value="value 3">
    <input type="checkbox" name="check_list[]" value="value 4">
    <input type="checkbox" name="check_list[]" value="value 5">
    <input type="submit" />
</form>
<?php
if(!empty($_POST['check_list'])) {
    foreach($_POST['check_list'] as $check) {
            echo $check; //echoes the value set in the HTML form for each checked checkbox.
                         //so, if I were to check 1, 3, and 5 it would echo value 1, value 3, value 5.
                         //in your case, it would echo whatever $row['Report ID'] is equivalent to.
    }
}
?>

As per my analysis and search on the internet also, I could not found a way to centre the image vertically centred using <div> it was possible only using <table> because table provides the following property:

valign="middle"

Just remove the fade class and if you want more animations to be perform on the Modal just use animate.css classes in your Modal.

def my_add_fn():
   print "SUM:%s"%sum(map(int,raw_input("Enter 2 numbers seperated by a space").split()))

def my_quit_fn():
   raise SystemExit

def invalid():
   print "INVALID CHOICE!"

menu = {"1":("Sum",my_add_fn),
        "2":("Quit",my_quit_fn)
       }
for key in sorted(menu.keys()):
     print key+":" + menu[key][0]

ans = raw_input("Make A Choice")
menu.get(ans,[None,invalid])[1]()

There is now (Chrome 76+ & FF 69+) a Blob.prototype.arrayBuffer() method which will return a Promise resolving with an ArrayBuffer representing the Blob's data.

How you detect EOF depends on what you're using to read the stream:

function                  result on EOF or error                    
--------                  ----------------------
fgets()                   NULL
fscanf()                  number of succesful conversions
                            less than expected
fgetc()                   EOF
fread()                   number of elements read
                            less than expected

Check the result of the input call for the appropriate condition above, then call feof() to determine if the result was due to hitting EOF or some other error.

Using fgets():

 char buffer[BUFFER_SIZE];
 while (fgets(buffer, sizeof buffer, stream) != NULL)
 {
   // process buffer
 }
 if (feof(stream))
 {
   // hit end of file
 }
 else
 {
   // some other error interrupted the read
 }

Using fscanf():

char buffer[BUFFER_SIZE];
while (fscanf(stream, "%s", buffer) == 1) // expect 1 successful conversion
{
  // process buffer
}
if (feof(stream)) 
{
  // hit end of file
}
else
{
  // some other error interrupted the read
}

Using fgetc():

int c;
while ((c = fgetc(stream)) != EOF)
{
  // process c
}
if (feof(stream))
{
  // hit end of file
}
else
{
  // some other error interrupted the read
}

Using fread():

char buffer[BUFFER_SIZE];
while (fread(buffer, sizeof buffer, 1, stream) == 1) // expecting 1 
                                                     // element of size
                                                     // BUFFER_SIZE
{
   // process buffer
}
if (feof(stream))
{
  // hit end of file
}
else
{
  // some other error interrupted read
}

Note that the form is the same for all of them: check the result of the read operation; if it failed, then check for EOF. You'll see a lot of examples like:

while(!feof(stream))
{
  fscanf(stream, "%s", buffer);
  ...
}

This form doesn't work the way people think it does, because feof() won't return true until after you've attempted to read past the end of the file. As a result, the loop executes one time too many, which may or may not cause you some grief.

Try this

header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
header("Content-Disposition: attachment;filename=\"filename.xlsx\"");
header("Cache-Control: max-age=0");

It's a way of taking small operation and putting it very close to where it is used (not unlike declaring a variable close to its use point). This is supposed to make your code more readable. By anonymizing the expression, you're also making it a lot harder for someone to break your client code if it the function is used somewhere else and modified to "enhance" it.

Similarly, why do you need to use foreach? You can do everything in foreach with a plain for loop or just using IEnumerable directly. Answer: you don't need it but it makes your code more readable.

You can also produce array by using file:

$array = file('/path/to/text.txt');

You want to use jQuery WayPoints. It is a very simple plugin and acheives exactly what you have described.

Most straightforward implementation

    $('.thing').waypoint(function(direction) {
  alert('Top of thing hit top of viewport.');
});

You will need to set some custom CSS to set exactly where it does become stuck, this is normal though for most ways to do it.

This page will show you all the examples and info that you need.

For future reference a example of it stopping and starting is this website. It is a "in the wild" example.

Check what $TERM gives: mine is xterm-color and ls -alG then does colorised output.

If you search for an image base-64 converter, you can embed some small image texture files as code into your @import url('') section of code. It will look like a lot of code; but at least all your data is now stored locally - rather than having to call a separate resource to load the image.

When I take a file from my own inventory of a simple icon in PNG format, and convert it to base-64, it looks like this in my CSS:

With your texture images, you'll want to employ a similar process.

Try something like this instead;

string illegal = "\"M\"\\a/ry/ h**ad:>> a\\/:*?\"| li*tt|le|| la\"mb.?";
string invalid = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());

foreach (char c in invalid)
{
    illegal = illegal.Replace(c.ToString(), ""); 
}

But I have to agree with the comments, I'd probably try to deal with the source of the illegal paths, rather than try to mangle an illegal path into a legitimate but probably unintended one.

Edit: Or a potentially 'better' solution, using Regex's.

string illegal = "\"M\"\\a/ry/ h**ad:>> a\\/:*?\"| li*tt|le|| la\"mb.?";
string regexSearch = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());
Regex r = new Regex(string.Format("[{0}]", Regex.Escape(regexSearch)));
illegal = r.Replace(illegal, "");

Still, the question begs to be asked, why you're doing this in the first place.

var l = str.length, lc = 0, chunks = [], c = 0, chunkSize = 2;
for (; lc < l; c++) {
  chunks[c] = str.slice(lc, lc += chunkSize);
}

You can write a generic filterByIndex() function and make use of type inference in TS to save the hassle with the callback function:

let's say you have your array [1,2,3,4] that you want to filter() with the indices specified in the [2,4] array.

var filtered = [1,2,3,4,].filter(byIndex(element => element, [2,4]))

the byIndex function expects the element function and an array and looks like this:

byIndex = (getter: (e:number) => number, arr: number[]) => (x: number) => {
    var i = getter(x);
    return arr.indexOf(i); 
}

result is then

filtered = [1,3]

This line looks suspicious:

invaders[i] = inv;

You're never incrementing i, so you keep assigning to invaders[0]. If this is just an error you made when reducing your code to the example, check how you calculate i in the real code; you could be exceeding the size of invaders.

If as your comment suggests, you're creating 55 invaders, then check that invaders has been initialised correctly to handle this number.

Example: fileA and fileB - start in fileA at line 25, copy 50 lines, and paste to fileB

fileA

Goto 25th line

25G

copy 50 lines into buffer v

"v50yy

Goto fileB

:e fileB

Goto line 10

10G    

paste contents of buffer v
"vp

module = __import__("my_package/my_module")
the_class = getattr(module, "MyClass")
obj = the_class()

Summarizing the solutions, I think that's the best one:

boolean isUiThread = VERSION.SDK_INT >= VERSION_CODES.M 
    ? Looper.getMainLooper().isCurrentThread()
    : Thread.currentThread() == Looper.getMainLooper().getThread();

And, if you wish to run something on the UI thread, you can use this:

new Handler(Looper.getMainLooper()).post(new Runnable() {
    @Override
    public void run() {
       //this runs on the UI thread
    }
});

Results

If you take a look at JQuery, you can do something like:

<iframe id="my_iframe" ...></iframe>

$('#my_iframe').contents().find('html').html();

This is assuming that your iframe parent and child reside on the same server, due to the Same Origin Policy in Javascript.

There is an easier way than the one written by CommonsWare. Just create a drawable resource that specifies the way the EditText will be drawn:

<?xml version="1.0" encoding="utf-8"?>
<!--  res/drawable/rounded_edittext.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" 
    android:padding="10dp">

    <solid android:color="#FFFFFF" />
    <corners
        android:bottomRightRadius="15dp"
        android:bottomLeftRadius="15dp"
        android:topLeftRadius="15dp"
        android:topRightRadius="15dp" />
</shape>

Then, just reference this drawable in your layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <EditText  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:padding="5dip"
        android:background="@drawable/rounded_edittext" />
</LinearLayout>

You will get something like:

Edit

Based on Mark's comment, I want to add the way you can create different states for your EditText:

<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/rounded_edittext_states.xml -->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:state_pressed="true" 
        android:state_enabled="true"
        android:drawable="@drawable/rounded_focused" />
    <item 
        android:state_focused="true" 
        android:state_enabled="true"
        android:drawable="@drawable/rounded_focused" />
    <item 
        android:state_enabled="true"
        android:drawable="@drawable/rounded_edittext" />
</selector>

These are the states:

<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/rounded_edittext_focused.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" android:padding="10dp">

    <solid android:color="#FFFFFF"/>
    <stroke android:width="2dp" android:color="#FF0000" />
    <corners
        android:bottomRightRadius="15dp"
        android:bottomLeftRadius="15dp"
        android:topLeftRadius="15dp"
        android:topRightRadius="15dp" />
</shape>

And... now, the EditText should look like:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <EditText  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:text="@string/hello"
        android:background="@drawable/rounded_edittext_states"
        android:padding="5dip" />
</LinearLayout>

This should work

gsub('\u009c','','\u009cYes yes for ever for ever the boys ')
"Yes yes for ever for ever the boys "

Here 009c is the hexadecimal number of unicode. You must always specify 4 hexadecimal digits. If you have many , one solution is to separate them by a pipe:

gsub('\u009c|\u00F0','','\u009cYes yes \u00F0for ever for ever the boys and the girls')

"Yes yes for ever for ever the boys and the girls"

Make's substitutions feature is nice and helped me to write

%.i: src/%.c $(INCLUDE)
        gcc -E $(CPPFLAGS) $(INCLUDE:%=-I %) $< > $@

You might find this useful, because it asks make to check for changes in include folders too

Don't store the whole structure in memory while waiting to get to the end.

Write intermediate results to a temporary table in the database instead of hashmaps - functionally, a database table is the equivalent of a hashmap, i.e. both support keyed access to data, but the table is not memory bound, so use an indexed table here rather than the hashmaps.

If done correctly, your algorithm should not even notice the change - correctly here means to use a class to represent the table, even giving it a put(key, value) and a get(key) method just like a hashmap.

When the intermediate table is complete, generate the required sql statement(s) from it instead of from memory.

In general, the best way to find any file in any arbitrary location is to start a terminal window and type in the classic Unix command "find":

find / -name index.html -print

Since the file you're looking for is the root file in the root directory of your web server, it's probably easier to find your web server's document root. For example, look under:

/var/www/*

Or type:

find /var/www -name index.html -print

Use System.in, it is an InputStream which just serves this purpose

Try this:

1. Add Microsoft.VisualBasic reference
2. Use: String result = Microsoft.VisualBasic.Strings.StrDup(5,"hi");
3. Let me know if it works for you.
