as Michael said,

Check the "Requires full screen" of the target of xcodeproj, if you don't need to support multitasking.

or Check the following device orientations

• Portrait
• Upside Down
• Landscape Left
• Landscape Right

In this case, we need to support launch storyboard.

According to solution showed by @sid-sha you have to put everything in the viewDidAppear: method, otherwise you will not get the didRotateFromInterfaceOrientation: fired, so something like:

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    UIInterfaceOrientation interfaceOrientation = [[UIApplication sharedApplication] statusBarOrientation];
    if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
        interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
        NSNumber *value = [NSNumber numberWithInt:interfaceOrientation];
        [[UIDevice currentDevice] setValue:value forKey:@"orientation"];
    }
}

I was in a similar problem than you. I need to lock device orientation for some screens (like Login) and allow rotation in others.

After a few changes and following some answers below I did it by:

• Enabling all the orientations in the Project's Info.plist.

• Disabling orientation in those ViewControllers where I need the device not to rotate, like in the Login screen in my case. I needed to override shouldAutorotate method in this VC:

-(BOOL)shouldAutorotate{ return NO; }

Hope this will work for you.

For is because is not have 2 function

@implementation CellTableView

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    return [self init];
}
- (void)awakeFromNib {
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];
}

@end

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

You can set an ENV if you want your Time.now and DateTime.now to respond in UTC time.

require 'date'
Time.now #=> 2015-11-30 11:37:14 -0800
DateTime.now.to_s #=> "2015-11-30T11:37:25-08:00"
ENV['TZ'] = 'UTC'
Time.now #=> 2015-11-30 19:37:38 +0000
DateTime.now.to_s #=> "2015-11-30T19:37:36+00:00"

Assuming all of these columns are int, then the first thing to sort out is converting one or more of them to a better data type - int division performs truncation, so anything less than 100% would give you a result of 0:

select (100.0 * (SPGI09_EARLY_OVER_T – SPGI09_OVER_WK_EARLY_ADJUST_T)) / (SPGI09_EARLY_OVER_T + SPGR99_LATE_CM_T  + SPGR99_ON_TIME_Q)
from 
CSPGI09_OVERSHIPMENT 

Here, I've mutiplied one of the numbers by 100.0 which will force the result of the calculation to be done with floats rather than ints. By choosing 100, I'm also getting it ready to be treated as a %.

I was also a little confused by your bracketing - I think I've got it correct - but you had brackets around single values, and then in other places you had a mix of operators (- and /) at the same level, and so were relying on the precedence rules to define which operator applied first.

The alternative for loop version to Kristo's answer.

You lose some efficiency, you go backwards and then forward again when deleting but in exchange for the extra iterator increment you can have the iterator declared in the loop scope and the code looking a bit cleaner. What to choose depends on priorities of the moment.

The answer was totally out of time, I know...

typedef std::list<item*>::iterator item_iterator;

for(item_iterator i = items.begin(); i != items.end(); ++i)
{
    bool isActive = (*i)->update();

    if (!isActive)
    {
        items.erase(i--); 
    }
    else
    {
        other_code_involving(*i);
    }
}

With C#9 came the Relational Pattern Matching. This allows us to do:

switch (value)
{
    case 1 or 2 or 3:
      // Do stuff
      break;
    case 4 or 5 or 6:
      // Do stuff
      break;
    default:
        // Do stuff
        break;
}

In deep tutorial of Relational Patter in C#9

Pattern-matching changes for C# 9.0

Relational patterns permit the programmer to express that an input value must satisfy a relational constraint when compared to a constant value

simply don't close in

remove in.close() from your code.

This is probably a very niche situation, but: I run Windows in a Parallels VM on my MacBook Pro, with my local repos stored on the VM's disk, which is shared with macOS.

If I have a file open in a Mac app from a repo that's located on the Windows VM, I sometimes get the "unable to update local ref" error. The solution when this happens is to simply close the file or quit the Mac app.

You need to pass an array of element to jsx. The problem is that forEach does not return anything (i.e it returns undefined). So it's better to use map because map returns an array:

class QuestionSet extends Component {
render(){ 
    <div className="container">
       <h1>{this.props.question.text}</h1>
       {this.props.question.answers.map((answer, i) => {     
           console.log("Entered");                 
           // Return the element. Also pass key     
           return (<Answer key={answer} answer={answer} />) 
        })}
}

export default QuestionSet;

Here's an example using jquery and your html.

        return false;
      }

    });
});

</script>

Here's an example with Alarm Manager using Kotlin:

class MainActivity : AppCompatActivity() {

    val editText: EditText by bindView(R.id.edit_text)
    val timePicker: TimePicker by bindView(R.id.time_picker)
    val buttonSet: Button by bindView(R.id.button_set)
    val buttonCancel: Button by bindView(R.id.button_cancel)
    val relativeLayout: RelativeLayout by bindView(R.id.activity_main)
    var notificationId = 0

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        timePicker.setIs24HourView(true)

        val alarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager

        buttonSet.setOnClickListener {
            if (editText.text.isBlank()) {
                Toast.makeText(applicationContext, "Title is Required!!", Toast.LENGTH_SHORT).show()
                return@setOnClickListener
            }
            alarmManager.set(
                AlarmManager.RTC_WAKEUP,
                Calendar.getInstance().apply {
                    set(Calendar.HOUR_OF_DAY, timePicker.hour)
                    set(Calendar.MINUTE, timePicker.minute)
                    set(Calendar.SECOND, 0)
                }.timeInMillis,
                PendingIntent.getBroadcast(
                    applicationContext,
                    0,
                    Intent(applicationContext, AlarmBroadcastReceiver::class.java).apply {
                        putExtra("notificationId", ++notificationId)
                        putExtra("reminder", editText.text)
                    },
                    PendingIntent.FLAG_CANCEL_CURRENT
                )
            )
            Toast.makeText(applicationContext, "SET!! ${editText.text}", Toast.LENGTH_SHORT).show()
            reset()
        }

        buttonCancel.setOnClickListener {
            alarmManager.cancel(
                PendingIntent.getBroadcast(
                    applicationContext, 0, Intent(applicationContext, AlarmBroadcastReceiver::class.java), 0))
            Toast.makeText(applicationContext, "CANCEL!!", Toast.LENGTH_SHORT).show()
        }
    }

    override fun onTouchEvent(event: MotionEvent?): Boolean {
        (getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager)
            .hideSoftInputFromWindow(relativeLayout.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
        relativeLayout.requestFocus()
        return super.onTouchEvent(event)
    }

    override fun onResume() {
        super.onResume()
        reset()
    }

    private fun reset() {
        timePicker.apply {
            val now = Calendar.getInstance()
            hour = now.get(Calendar.HOUR_OF_DAY)
            minute = now.get(Calendar.MINUTE)
        }
        editText.setText("")
    }
}

Realizing this is a bit of an old question, the responses helped me come up with a solution to testing command line arguments to a batch file; so I wanted to post my solution as well in case anyone else was looking for a similar solution.

First thing that I should point out is that I was having trouble getting IF ... ELSE statements to work inside of a FOR ... DO clause. Turns out (thanks to dbenham for inadvertently pointing this out in his examples) the ELSE statement cannot be on a separate line from the closing parens.

So instead of this:

FOR ... DO (
    IF ... (
    )
    ELSE (
    )
)

Which is my preference for readability and aesthetic reasons, you have to do this:

FOR ... DO (
    IF ... (
    ) ELSE (
    )
)

Now the ELSE statement doesn't return as an unrecognized command.

Finally, here's what I was attempting to do - I wanted to be able to pass several arguments to a batch file in any order, ignoring case, and reporting/failing on undefined arguments passed in. So here's my solution...

@ECHO OFF
SET ARG1=FALSE
SET ARG2=FALSE
SET ARG3=FALSE
SET ARG4=FALSE
SET ARGS=(arg1 Arg1 ARG1 arg2 Arg2 ARG2 arg3 Arg3 ARG3)
SET ARG=

FOR %%A IN (%*) DO (
    SET TRUE=
    FOR %%B in %ARGS% DO (
        IF [%%A] == [%%B] SET TRUE=1
        )
    IF DEFINED TRUE (
        SET %%A=TRUE
        ) ELSE (
        SET ARG=%%A
        GOTO UNDEFINED
        )
    )

ECHO %ARG1%
ECHO %ARG2%
ECHO %ARG3%
ECHO %ARG4%
GOTO END

:UNDEFINED
ECHO "%ARG%" is not an acceptable argument.
GOTO END

:END

Note, this will only report on the first failed argument. So if the user passes in more than one unacceptable argument, they will only be told about the first until it's corrected, then the second, etc.

I faced the same problem,but after hours of efforts i find the solution.It can be without using any external plugin:)

applicantListToExport: function (query, callback) {
  this
   .find(query).select({'advtId': 0})
   .populate({
      path: 'influId',
      model: 'influencer',
      select: { '_id': 1,'user':1},
      populate: {
        path: 'userid',
        model: 'User'
      }
   })
 .populate('campaignId',{'campaignTitle':1})
 .exec(callback);
}

For anyone looking for a full solution, I got this working with the following code based on maximdim's answer:

import javax.mail.*
import javax.mail.internet.*

private class SMTPAuthenticator extends Authenticator
{
    public PasswordAuthentication getPasswordAuthentication()
    {
        return new PasswordAuthentication('[email protected]', 'test1234');
    }
}

def  d_email = "[email protected]",
        d_uname = "email",
        d_password = "password",
        d_host = "smtp.gmail.com",
        d_port  = "465", //465,587
        m_to = "[email protected]",
        m_subject = "Testing",
        m_text = "Hey, this is the testing email."

def props = new Properties()
props.put("mail.smtp.user", d_email)
props.put("mail.smtp.host", d_host)
props.put("mail.smtp.port", d_port)
props.put("mail.smtp.starttls.enable","true")
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.auth", "true")
props.put("mail.smtp.socketFactory.port", d_port)
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory")
props.put("mail.smtp.socketFactory.fallback", "false")

def auth = new SMTPAuthenticator()
def session = Session.getInstance(props, auth)
session.setDebug(true);

def msg = new MimeMessage(session)
msg.setText(m_text)
msg.setSubject(m_subject)
msg.setFrom(new InternetAddress(d_email))
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to))

Transport transport = session.getTransport("smtps");
transport.connect(d_host, 465, d_uname, d_password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();

Apply the color to the li and set the span (or other child element) color to whatever color the text should be.

ul
{
    list-style-type: square;
}

ul > li
{
    color: green;
}

ul > li > span
{
    color: black;
}

JSFiddle

I had this problem, it is for foreign-key

Click on the Relation View (like the image below) then find name of the field you are going to remove it, and under the Foreign key constraint (INNODB) column, just put the select to nothing! Means no foreign-key

Hope that works!

%...% operators

%>% has no builtin meaning but the user (or a package) is free to define operators of the form %whatever% in any way they like. For example, this function will return a string consisting of its left argument followed by a comma and space and then it's right argument.

"%,%" <- function(x, y) paste0(x, ", ", y)

# test run

"Hello" %,% "World"
## [1] "Hello, World"

The base of R provides %*% (matrix mulitiplication), %/% (integer division), %in% (is lhs a component of the rhs?), %o% (outer product) and %x% (kronecker product). It is not clear whether %% falls in this category or not but it represents modulo.

expm The R package, expm, defines a matrix power operator %^%. For an example see Matrix power in R .

operators The operators R package has defined a large number of such operators such as %!in% (for not %in%). See http://cran.r-project.org/web/packages/operators/operators.pdf

igraph This package defines %--% , %->% and %<-% to select edges.

lubridate This package defines %m+% and %m-% to add and subtract months and %--% to define an interval. igraph also defines %--% .

Pipes

magrittr In the case of %>% the magrittr R package has defined it as discussed in the magrittr vignette. See http://cran.r-project.org/web/packages/magrittr/vignettes/magrittr.html

magittr has also defined a number of other such operators too. See the Additional Pipe Operators section of the prior link which discusses %T>%, %<>% and %$% and http://cran.r-project.org/web/packages/magrittr/magrittr.pdf for even more details.

dplyr The dplyr R package used to define a %.% operator which is similar; however, it has been deprecated and dplyr now recommends that users use %>% which dplyr imports from magrittr and makes available to the dplyr user. As David Arenburg has mentioned in the comments this SO question discusses the differences between it and magrittr's %>% : Differences between %.% (dplyr) and %>% (magrittr)

pipeR The R package, pipeR, defines a %>>% operator that is similar to magrittr's %>% and can be used as an alternative to it. See http://renkun.me/pipeR-tutorial/

The pipeR package also has defined a number of other such operators too. See: http://cran.r-project.org/web/packages/pipeR/pipeR.pdf

postlogic The postlogic package defined %if% and %unless% operators.

wrapr The R package, wrapr, defines a dot pipe %.>% that is an explicit version of %>% in that it does not do implicit insertion of arguments but only substitutes explicit uses of dot on the right hand side. This can be considered as another alternative to %>%. See https://winvector.github.io/wrapr/articles/dot_pipe.html

Bizarro pipe. This is not really a pipe but rather some clever base syntax to work in a way similar to pipes without actually using pipes. It is discussed in http://www.win-vector.com/blog/2017/01/using-the-bizarro-pipe-to-debug-magrittr-pipelines-in-r/ The idea is that instead of writing:

1:8 %>% sum %>% sqrt
## [1] 6

one writes the following. In this case we explicitly use dot rather than eliding the dot argument and end each component of the pipeline with an assignment to the variable whose name is dot (.) . We follow that with a semicolon.

1:8 ->.; sum(.) ->.; sqrt(.)
## [1] 6

Update Added info on expm package and simplified example at top. Added postlogic package.

It means, essentially, what it says; that 'this is important, ignore subsequent rules, and any usual specificity issues, apply this rule!'

In normal use a rule defined in an external stylesheet is overruled by a style defined in the head of the document, which, in turn, is overruled by an in-line style within the element itself (assuming equal specificity of the selectors). Defining a rule with the !important 'attribute' (?) discards the normal concerns as regards the 'later' rule overriding the 'earlier' ones.

Also, ordinarily, a more specific rule will override a less-specific rule. So:

a {
    /* css */
}

Is normally overruled by:

body div #elementID ul li a {
    /* css */
}

As the latter selector is more specific (and it doesn't, normally, matter where the more-specific selector is found (in the head or the external stylesheet) it will still override the less-specific selector (in-line style attributes will always override the 'more-', or the 'less-', specific selector as it's always more specific.

If, however, you add !important to the less-specific selector's CSS declaration, it will have priority.

Using !important has its purposes (though I struggle to think of them), but it's much like using a nuclear explosion to stop the foxes killing your chickens; yes, the foxes will be killed, but so will the chickens. And the neighbourhood.

It also makes debugging your CSS a nightmare (from personal, empirical, experience).

This worked for me:

fun timeBetweenInterval(
    openTime: String,
    closeTime: String
): Boolean {
    try {
        val dateFormat = SimpleDateFormat(TIME_FORMAT)
        val afterCalendar = Calendar.getInstance().apply {
            time = dateFormat.parse(openTime)
            add(Calendar.DATE, 1)
        }
        val beforeCalendar = Calendar.getInstance().apply {
            time = dateFormat.parse(closeTime)
            add(Calendar.DATE, 1)
        }

        val current = Calendar.getInstance().apply {
            val localTime = dateFormat.format(timeInMillis)
            time = dateFormat.parse(localTime)
            add(Calendar.DATE, 1)
        }
        return current.time.after(afterCalendar.time) && current.time.before(beforeCalendar.time)
    } catch (e: ParseException) {
        e.printStackTrace()
        return false
    }
}

Here is a full-fledged css solution inspired by Bulma. Just add

    .button {
      display: inline-flex;
      align-items: center;
      justify-content: center;
      position: relative;
      min-width: 200px;
      max-width: 100%;
      min-height: 40px;
      text-align: center;
      cursor: pointer;
    }

    @-webkit-keyframes spinAround {
      from {
        -webkit-transform: rotate(0deg);
        transform: rotate(0deg);
      }
      to {
        -webkit-transform: rotate(359deg);
        transform: rotate(359deg);
      }
    }
    @keyframes spinAround {
      from {
        -webkit-transform: rotate(0deg);
        transform: rotate(0deg);
      }
      to {
        -webkit-transform: rotate(359deg);
        transform: rotate(359deg);
      }
    }

    .button.is-loading {
      text-indent: -9999px;
      box-shadow: none;
      font-size: 1rem;
      height: 2.25em;
      line-height: 1.5;
      vertical-align: top;
      padding-bottom: calc(0.375em - 1px);
      padding-left: 0.75em;
      padding-right: 0.75em;
      padding-top: calc(0.375em - 1px);
      white-space: nowrap;
    }

    .button.is-loading::after  {
      -webkit-animation: spinAround 500ms infinite linear;
      animation: spinAround 500ms infinite linear;
      border: 2px solid #dbdbdb;
      border-radius: 290486px;
      border-right-color: transparent;
      border-top-color: transparent;
      content: "";
      display: block;
      height: 1em;
      position: relative;
      width: 1em;
    }

In Chrome, click the 3 dots and click More tools and click developer. On the console, type console.dir(yourObject).Click this link to view an example image

It turns out that it was shrinking and growing correctly, providing the desired behaviour all along; except that in all current browsers flexbox wasn't accounting for the vertical scrollbar! Which is why the content appears to be getting cut off.

You can see here, which is the original code I was using before I added the fixed widths, that it looks like the column isn't growing to accomodate the text:

http://jsfiddle.net/2w157dyL/1/

However if you make the content in that column wider, you'll see that it always cuts it off by the same amount, which is the width of the scrollbar.

So the fix is very, very simple - add enough right padding to account for the scrollbar:

http://jsfiddle.net/2w157dyL/2/

  main > section {_x000D_
    overflow-y: auto;_x000D_
    padding-right: 2em;_x000D_
  }

It was when I was trying some things suggested by Michael_B (specifically adding a padding buffer) that I discovered this, thanks so much!

Edit: I see that he also posted a fiddle which does the same thing - again, thanks so much for all your help

Residuum did provide a correct answer to how you should get shell exec to find your script, but in regards to security, there are a couple of points.

I would imagine you don't want your shell script to be in your web root, as it would be visible to anyone with web access to your server.

I would recommend moving the shell script to outside of the webroot

    <?php
      $tempFolder = '/tmp';
      $webRootFolder = '/var/www';
      $scriptName = 'myscript.sh';
      $moveCommand = "mv $webRootFolder/$scriptName $tempFolder/$scriptName";
      $output = shell_exec($moveCommand);
    ?>

In regards to the:

i added www-data ALL=(ALL) NOPASSWD:ALL to /etc/sudoers works

You can modify this to only cover the specific commands in your script which require sudo. Otherwise, if none of the commands in your sh script require sudo to execute, you don't need to do this at all anyway.

Try running the script as the apache user (use the su command to switch to the apache user) and if you are not prompted for sudo or given permission denied, etc, it'll be fine.

ie:

sudo su apache (or www-data)
cd /var/www
sh ./myscript

Also... what brought me here was that I wanted to run a multi line shell script using commands that are dynamically generated. I wanted all of my commands to run in the same shell, which won't happen using multiple calls to shell_exec(). The answer to that one is to do it like Jenkins - create your dynamically generated multi line of commands, put it in a variable, save it to a file in a temp folder, execute that file (using shell_exec in() php as Jenkins is Java), then do whatever you want with the output, and delete the temp file

... voila

I'm a little late to the party, but maybe this could help. The link in the question had a similar formula, but mine uses the IF() statement to get rid of errors.

If you're not afraid of Ctrl+Shift+Enter, you can do pretty well with an array formula.

String (in cell A1): "one.two.three.four"

Formula:

{=MAX(IF(MID(A1,ROW($1:$99),1)=".",ROW($1:$99)))}  use Ctrl+Shift+Enter

Result: 14

First,

ROW($1:$99)

returns an array of integers from 1 to 99: {1,2,3,4,...,98,99}.

Next,

MID(A1,ROW($1:$99),1)

returns an array of 1-length strings found in the target string, then returns blank strings after the length of the target string is reached: {"o","n","e",".",..."u","r","","",""...}

Next,

IF(MID(I16,ROW($1:$99),1)=".",ROW($1:$99))

compares each item in the array to the string "." and returns either the index of the character in the string or FALSE: {FALSE,FALSE,FALSE,4,FALSE,FALSE,FALSE,8,FALSE,FALSE,FALSE,FALSE,FALSE,14,FALSE,FALSE.....}

Last,

=MAX(IF(MID(I16,ROW($1:$99),1)=".",ROW($1:$99)))

returns the maximum value of the array: 14

Advantages of this formula is that it is short, relatively easy to understand, and doesn't require any unique characters.

Disadvantages are the required use of Ctrl+Shift+Enter and the limitation on string length. This can be worked around with a variation shown below, but that variation uses the OFFSET() function which is a volatile (read: slow) function.

Not sure what the speed of this formula is vs. others.

Variations:

=MAX((MID(A1,ROW(OFFSET($A$1,,,LEN(A1))),1)=".")*ROW(OFFSET($A$1,,,LEN(A1)))) works the same way, but you don't have to worry about the length of the string

=SMALL(IF(MID(A1,ROW($1:$99),1)=".",ROW($1:$99)),2) determines the 2nd occurrence of the match

=LARGE(IF(MID(A1,ROW($1:$99),1)=".",ROW($1:$99)),2) determines the 2nd-to-last occurrence of the match

=MAX(IF(MID(I16,ROW($1:$99),2)=".t",ROW($1:$99))) matches a 2-character string **Make sure you change the last argument of the MID() function to the number of characters in the string you wish to match!

I don't know why all the answers over here are so confusing. I found a quite simpler one. Use a css class for the asp:menu, say, mainMenu and all the menu items under this will be "a tags" when rendered into HTML. So you just have to provide :hover property to those "a tags" in your CSS. See below for the example:

<asp:Menu ID="mnuMain" Orientation="Horizontal" runat="server" Font-Bold="True" Width="100%" CssClass="mainMenu">
  <Items>
    <asp:MenuItem Text="Home"></asp:MenuItem>
    <asp:MenuItem Text="About Us"></asp:MenuItem>
  </Items>
</asp:Menu>

And in the CSS, write:

.mainMenu { background:#900; }
.mainMenu a { color:#fff; }
.mainMenu a:hover { background:#c00; color:#ff9; }

I hope this helps. :)

import pandas as pd
dataset = pd.read_csv('/home/nspython/Downloads/movie_metadata1.csv')

The problem solved when I don't use any declaration like var, let or const

function GetTableLng(tbl)
  local getN = 0
  for n in pairs(tbl) do 
    getN = getN + 1 
  end
  return getN
end

You're right. There are no other way to get length of table

Usually used for embedding custom data, like pictures or sound data within an XML document.

public string RemoveSpecial(string evalstr)
{
StringBuilder finalstr = new StringBuilder();
            foreach(char c in evalstr){
            int charassci = Convert.ToInt16(c);
            if (!(charassci >= 33 && charassci <= 47))// special char ???
             finalstr.append(c);
            }
return finalstr.ToString();
}

The Observable Collection constructor will take an IList or an IEnumerable.

If you find that you are going to do this a lot you can make a simple extension method:

    public static ObservableCollection<T> ToObservableCollection<T>(this IEnumerable<T> enumerable)
    {
        return new ObservableCollection<T>(enumerable);
    }

One of the reasons that C++ was designed was to make it easy to reuse code. In general, C++ should be written so that it works whether the class is instantiated on the heap, in an array, or on the stack. "Delete this" is a very bad coding practice because it will only work if a single instance is defined on the heap; and there had better not be another delete statement, which is typically used by most developers to clean up the heap. Doing this also assumes that no maintenance programmer in the future will cure a falsely perceived memory leak by adding a delete statement.

Even if you know in advance that your current plan is to only allocate a single instance on the heap, what if some happy-go-lucky developer comes along in the future and decides to create an instance on the stack? Or, what if he cuts and pastes certain portions of the class to a new class that he intends to use on the stack? When the code reaches "delete this" it will go off and delete it, but then when the object goes out of scope, it will call the destructor. The destructor will then try to delete it again and then you are hosed. In the past, doing something like this would screw up not only the program but the operating system and the computer would need to be rebooted. In any case, this is highly NOT recommended and should almost always be avoided. I would have to be desperate, seriously plastered, or really hate the company I worked for to write code that did this.

The most likely place to find this sort of information is in the event viewer (under Administrative tools in XP or run eventvwr) This is where most services log warnings errors etc.

After reading all of the above, I prefer the following statement:

SELECT EXISTS(
       SELECT * FROM information_schema.tables 
       WHERE table_schema = 'db' 
       AND table_name = 'table'
);

It indicates exactly what you want to do and it actually returns a 'boolean'.

If you're trying to grab a range with a dynamically generated string, then you just have to build the string like this:

Range(firstcol & firstrow & ":" & secondcol & secondrow).Select

I got that error, when sometimes I type in Chinese language. When it comes to punctuation marks, you do not notice that you are actually typing the Chinese version, instead of the English version.

The interpreter will give you an error message, but for human eyes, it is hard to notice the difference.

For example, "," in Chinese; and "," in English. So be careful with your language setting.

Campaign Monitor have an excellent support matrix detailing what's supported and what isn't among various mail clients.

You can use a service like Litmus to view how an email appears across several clients and whether they get caught by filters, etc.

I was having the same issue. I needed to export the column header using SQL server bcp utility.This way I exported table "headers" with data into same exported file in one go.

DECLARE @table_name  VARCHAR(50) ='mytable'
DECLARE @columnHeader VARCHAR(8000)
SELECT @columnHeader = COALESCE(@columnHeader+',' ,'')+ ''''+column_name +'''' FROM Nal2013.INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME=@table_name
SELECT @raw_sql = 'bcp "SELECT '+ @columnHeader +' UNION ALL SELECT * FROM mytable" queryout c:\datafile.csv -c -t, -T -S '+ @@servername
EXEC  xp_cmdshell @raw_sql

Happy coding :)

Here is a dplyr solution:

df %>% select_if(~sum(!is.na(.)) > 0)

Update: The summarise_if() function is superseded as of dplyr 1.0. Here are two other solutions that use the where() tidyselect function:

df %>% 
  select(
    where(
      ~sum(!is.na(.x)) > 0
    )
  )

df %>% 
  select(
    where(
      ~!all(is.na(.x))
    )
  )

A TCP/IP connection is always made to an IP address (you can think of an IP-address as the address of a certain computer, even if that is not always the case) and a specific (logical, not physical) port on that address.

Usually one port is coupled to a specific process or "service" on the target computer. Some port numbers are standardized, like 80 for http, 25 for smtp and so on. Because of that standardization you usually don't need to put port numbers into your web adresses.

So if you say something like http://www.stackoverflow.com, the part "stackoverflow.com" resolves to an IP address (in my case 64.34.119.12) and because my browser knows the standard it tries to connect to port 80 on that address. Thus this is the same as http://www.stackoverflow.com:80.

But there is nothing that stops a process to listen for http requests on another port, like 12434, 4711 or 8080. Usually (as in your case) this is used for debugging purposes to not intermingle with another process (like IIS) already listening to port 80 on the same machine.

There are various ways to achieve this. Here are three.

    Map<String, String> map = new HashMap<String, String>();
    map.put("key1", "value1");
    map.put("key2", "value2");
    map.put("key3", "value3");

    System.out.println("using entrySet and toString");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry);
    }
    System.out.println();

    System.out.println("using entrySet and manual string creation");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry.getKey() + "=" + entry.getValue());
    }
    System.out.println();

    System.out.println("using keySet");
    for (String key : map.keySet()) {
        System.out.println(key + "=" + map.get(key));
    }
    System.out.println();

Output

using entrySet and toString
key1=value1
key2=value2
key3=value3

using entrySet and manual string creation
key1=value1
key2=value2
key3=value3

using keySet
key1=value1
key2=value2
key3=value3

This is a version of Jane Sales' answer in Swift. Cheers!

public func resizeImage(image: UIImage, size: CGSize) -> UIImage? {
    var returnImage: UIImage?

    var scaleFactor: CGFloat = 1.0
    var scaledWidth = size.width
    var scaledHeight = size.height
    var thumbnailPoint = CGPointMake(0, 0)

    if !CGSizeEqualToSize(image.size, size) {
        let widthFactor = size.width / image.size.width
        let heightFactor = size.height / image.size.height

        if widthFactor > heightFactor {
            scaleFactor = widthFactor
        } else {
            scaleFactor = heightFactor
        }

        scaledWidth = image.size.width * scaleFactor
        scaledHeight = image.size.height * scaleFactor

        if widthFactor > heightFactor {
            thumbnailPoint.y = (size.height - scaledHeight) * 0.5
        } else if widthFactor < heightFactor {
            thumbnailPoint.x = (size.width - scaledWidth) * 0.5
        }
    }

    UIGraphicsBeginImageContextWithOptions(size, true, 0)

    var thumbnailRect = CGRectZero
    thumbnailRect.origin = thumbnailPoint
    thumbnailRect.size.width = scaledWidth
    thumbnailRect.size.height = scaledHeight

    image.drawInRect(thumbnailRect)
    returnImage = UIGraphicsGetImageFromCurrentImageContext()

    UIGraphicsEndImageContext()

    return returnImage
}

Since in many cases an empty map is used for null-safe design, you can utilize the nullToEmpty utility method:

class MapUtils {

  static <K,V> Map<K,V> nullToEmpty(Map<K,V> map) {
    if (map != null) {
      return map;
    } else {
       return Collections.<K,V>emptyMap(); // or guava ImmutableMap.of()
    }
  }

}  

Similarly for sets:

class SetUtils {

  static <T> Set<T> nullToEmpty(Set<T> set) {
    if (set != null) {
      return set;
    } else {
      return Collections.<T>emptySet();
    }
  }

}

and lists:

class ListUtils {

  static <T> List<T> nullToEmpty(List<T> list) {
    if (list != null) {
      return list;
    } else {
      return Collections.<T>emptyList();
    }
  }

}

There are several ways:

Instantiating the array:

var arr;

arr = new Array(); // empty array

// ---

arr = [];          // empty array

// ---

arr = new Array(3);
alert(arr.length);  // 3
alert(arr[0]); // undefined

// ---

arr = [3];
alert(arr.length);  // 1
alert(arr[0]); // 3

Pushing to the array:

arr = [3];     // arr == [3]
arr[1] = 4;    // arr == [3, 4]
arr[2] = 5;    // arr == [3, 4, 5]
arr[4] = 7;    // arr == [3, 4, 5, undefined, 7]

// ---

arr = [3];
arr.push(4);        // arr == [3, 4]
arr.push(5);        // arr == [3, 4, 5]
arr.push(6, 7, 8);  // arr == [3, 4, 5, 6, 7, 8]

Using .push() is the better way to add to an array, since you don't need to know how many items are already there, and you can add many items in one function call.

Using ADB, you can use any of the following three commands:

adb shell am start -a android.intent.action.UNINSTALL_PACKAGE -d "package:PACKAGE"
adb shell am start -n com.android.packageinstaller/.UninstallerActivity -d "package:PACKAGE"
adb shell am start -a android.intent.action.DELETE -d "package:PACKAGE"

Replace PACKAGE with package name of the installed user app. The app mustn't be a device administrator for the command to work successfully. All of those commands would require user's confirmation for removal of app.

Details of the said command can be known by checking am's usage using adb shell am.

I got the info about those commands using Elixir 2 (use any equivalent app). I used it to show the activities of Package Installer app (the GUI that you see during installation and removal of apps) as well as the related intents. There you go.

The alternative way I used was: I attempted to uninstall the app using GUI until I was shown the final confirmation. I didn't confirm but execute the command

adb shell dumpsys activity recents   # for Android 4.4 and above
adb shell dumpsys activity activities # for Android 4.2.1

Among other things, it showed me useful details of the intent passed in the background. Example:

intent={act=android.intent.action.DELETE dat=package:com.bartat.android.elixir#com.bartat.android.elixir.MainActivity flg=0x10800000 cmp=com.android.packageinstaller/.UninstallerActivity}

Here, you can see the action, data, flag and component - enough for the goal.

With Java 8, you can do this:

int[] haystack = {1, 2, 3};
int needle = 3;

boolean found = Arrays.stream(haystack).anyMatch(x -> x == needle);

You'd need to do

boolean found = Arrays.stream(haystack).anyMatch(x -> needle.equals(x));

if you're working with objects.

select field1, field2, 'example' as TempField
from table1

This should work across different SQL implementations.

There may be many ways.. But I implemented by following two ways

Given example is of maven project.

1. Using Dockerfile in maven project

Use the following file structure:

Demo
+-- src
|    +-- main
|    ¦   +-- java
|    ¦       +-- org
|    ¦           +-- demo
|    ¦               +-- Application.java
|    ¦   
|    +-- test
|
+---- Dockerfile
+---- pom.xml

And update the Dockerfile as:

FROM java:8
EXPOSE 8080
ADD /target/demo.jar demo.jar
ENTRYPOINT ["java","-jar","demo.jar"]

Navigate to the project folder and type following command you will be ab le to create image and run that image:

$ mvn clean
$ mvn install
$ docker build -f Dockerfile -t springdemo .
$ docker run -p 8080:8080 -t springdemo

Get video at Spring Boot with Docker

2. Using Maven plugins

Add given maven plugin in pom.xml

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <version>0.4.5</version>
        <configuration>
            <imageName>springdocker</imageName>
            <baseImage>java</baseImage>
            <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>
            <resources>
                <resource>
                    <targetPath>/</targetPath>
                    <directory>${project.build.directory}</directory>
                    <include>${project.build.finalName}.jar</include>
                </resource>
            </resources>
        </configuration>
    </plugin>

Navigate to the project folder and type following command you will be able to create image and run that image:

$ mvn clean package docker:build
$ docker images
$ docker run -p 8080:8080 -t <image name>

In first example we are creating Dockerfile and providing base image and adding jar an so, after doing that we will run docker command to build an image with specific name and then run that image..

Whereas in second example we are using maven plugin in which we providing baseImage and imageName so we don't need to create Dockerfile here.. after packaging maven project we will get the docker image and we just need to run that image..

Void is the equivalent of Visual Basic's Sub.

This may be overkill for a simple breadcrumb, but it's worth a shot. I remember having this issue a long time ago when I first started, but I never really solved it. That is, until I just decided to write this up now. :)

I have documented as best I can inline, at the bottom are 3 possible use cases. Enjoy! (feel free to ask any questions you may have)

<?php

// This function will take $_SERVER['REQUEST_URI'] and build a breadcrumb based on the user's current path
function breadcrumbs($separator = ' &raquo; ', $home = 'Home') {
    // This gets the REQUEST_URI (/path/to/file.php), splits the string (using '/') into an array, and then filters out any empty values
    $path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));

    // This will build our "base URL" ... Also accounts for HTTPS :)
    $base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';

    // Initialize a temporary array with our breadcrumbs. (starting with our home page, which I'm assuming will be the base URL)
    $breadcrumbs = Array("<a href=\"$base\">$home</a>");

    // Find out the index for the last value in our path array
    $last = end(array_keys($path));

    // Build the rest of the breadcrumbs
    foreach ($path AS $x => $crumb) {
        // Our "title" is the text that will be displayed (strip out .php and turn '_' into a space)
        $title = ucwords(str_replace(Array('.php', '_'), Array('', ' '), $crumb));

        // If we are not on the last index, then display an <a> tag
        if ($x != $last)
            $breadcrumbs[] = "<a href=\"$base$crumb\">$title</a>";
        // Otherwise, just display the title (minus)
        else
            $breadcrumbs[] = $title;
    }

    // Build our temporary array (pieces of bread) into one big string :)
    return implode($separator, $breadcrumbs);
}

?>

<p><?= breadcrumbs() ?></p>
<p><?= breadcrumbs(' > ') ?></p>
<p><?= breadcrumbs(' ^^ ', 'Index') ?></p>

Use the built-in isinstance() function.

import pandas as pd

def f(var):
    if isinstance(var, pd.DataFrame):
        print("do stuff")

The following works for me:

Map<String, String> propertyMap = getJsonAsMap(json);

where getJsonAsMap is defined like so:

public HashMap<String, String> getJsonAsMap(String json)
{
    try
    {
        ObjectMapper mapper = new ObjectMapper();
        TypeReference<Map<String,String>> typeRef = new TypeReference<Map<String,String>>() {};
        HashMap<String, String> result = mapper.readValue(json, typeRef);

        return result;
    }
    catch (Exception e)
    {
        throw new RuntimeException("Couldnt parse json:" + json, e);
    }
}

Note that this will fail if you have child objects in your json (because they're not a String, they're another HashMap), but will work if your json is a key value list of properties like so:

{
    "client_id": "my super id",
    "exp": 1481918304,
    "iat": "1450382274",
    "url": "http://www.example.com"
}

Just import tensortflow and use keras, it's that easy.

import tensorflow as tf
# your code here
with tf.device('/gpu:0'):
    model.fit(X, y, epochs=20, batch_size=128, callbacks=callbacks_list)

catch needs to return an observable.

.catch(e => { console.log(e); return Observable.of(e); })

if you'd like to stop the pipeline after a caught error, then do this:

.catch(e => { console.log(e); return Observable.of(null); }).filter(e => !!e)

this catch transforms the error into a null val and then filter doesn't let falsey values through. This will however, stop the pipeline for ANY falsey value, so if you think those might come through and you want them to, you'll need to be more explicit / creative.

edit:

better way of stopping the pipeline is to do

.catch(e => Observable.empty())

In my case it works just commenting (or deleting) the anonymousAuthentication property:

 <security>
     <authentication>
         <!--<anonymousAuthentication enabled="true" />-->
     </authentication>
 </security>

Maybe you can try to add android:layout_marginTop = "15dp" and android:layout_marginBottom = "15dp" in the outermost Layout

In my sql use information function

select FOUND_ROWS();

it will return the no. of rows returned by select query.

All the info is in the other answers, but none summarizes both your requests or seem to make things needlessly complex:

• For your removal needs use:

  pip uninstall <package>
  

  (install using easy_install pip)

• For your 'list installed packages' needs either use:

  pip freeze
  

  Or:

  yolk -l
  

  which can output more package details.

  (Install via easy_install yolk or pip install yolk)

Is this what you're looking for?

#include <chrono>
#include <iostream>

int main()
{
    typedef std::chrono::high_resolution_clock Time;
    typedef std::chrono::milliseconds ms;
    typedef std::chrono::duration<float> fsec;
    auto t0 = Time::now();
    auto t1 = Time::now();
    fsec fs = t1 - t0;
    ms d = std::chrono::duration_cast<ms>(fs);
    std::cout << fs.count() << "s\n";
    std::cout << d.count() << "ms\n";
}

which for me prints out:

6.5e-08s
0ms

I also had this issue using Lumen, but fixed by setting DB_STRICT_MODE=false in .env file.

You can use INFORMATION_SCHEMA.TABLES to retrieve information about your database tables.

As mentioned in the Microsoft Tables Documentation:

INFORMATION_SCHEMA.TABLES returns one row for each table in the current database for which the current user has permissions.

The following query, therefore, will return the number of tables in the specified database:

USE MyDatabase
SELECT COUNT(*)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'

As of SQL Server 2008, you can also use sys.tables to count the the number of tables.

From the Microsoft sys.tables Documentation:

sys.tables returns a row for each user table in SQL Server.

The following query will also return the number of table in your database:

SELECT COUNT(*)
FROM sys.tables

See ?substring.

x <- 'hello stackoverflow'
substring(x, 1, 1)
## [1] "h"
substring(x, 2)
## [1] "ello stackoverflow"

The idea of having a pop method that both returns a value and has a side effect of updating the data stored in x is very much a concept from object-oriented programming. So rather than defining a pop function to operate on character vectors, we can make a reference class with a pop method.

PopStringFactory <- setRefClass(
  "PopString",
  fields = list(
    x = "character"  
  ),
  methods = list(
    initialize = function(x)
    {
      x <<- x
    },
    pop = function(n = 1)
    {
      if(nchar(x) == 0)
      {
        warning("Nothing to pop.")
        return("")
      }
      first <- substring(x, 1, n)
      x <<- substring(x, n + 1)
      first
    }
  )
)

x <- PopStringFactory$new("hello stackoverflow")
x
## Reference class object of class "PopString"
## Field "x":
## [1] "hello stackoverflow"
replicate(nchar(x$x), x$pop())
## [1] "h" "e" "l" "l" "o" " " "s" "t" "a" "c" "k" "o" "v" "e" "r" "f" "l" "o" "w"

m <- matrix(1:20, ncol = 4) 
colnames(m) <- letters[1:4]

The following command will select the first row of the matrix above.

subset(m, m[,4] == 16)

And this will select the last three.

subset(m, m[,4] > 17)

The result will be a matrix in both cases. If you want to use column names to select columns then you would be best off converting it to a dataframe with

mf <- data.frame(m)

Then you can select with

mf[ mf$a == 16, ]

Or, you could use the subset command.

You have multiple ways to do this.

1:

location.href;

2:

document.URL;

3:

document.documentURI;

the easiest way would be

new File(filename).getText()

which means you could just do:

new File(filename).text

As the official specification says, "one or more different sets of data are combined in a single body". So when photos and music are handled as multipart messages as mentioned in the question, probably there is some plain text metadata associated as well, thus making the request containing different types of data (binary, text), which implies the usage of multipart.

data = 'data you want inside the file'.

You can use File.write('name of file here', data)

This worked for me :

npm install -g local-cors-proxy

API endpoint that we want to request that has CORS issues:

https://www.yourdomain.com/test/list

Start Proxy:

lcp --proxyUrl https://www.yourdomain.com

 Proxy Active 

 Proxy Url: http://www.yourdomain.com:28080
 Proxy Partial: proxy
 PORT: 8010

Then in your client code, new API endpoint:

http://localhost:8010/proxy/test/list

End result will be a request to https://www.yourdomain.ie/test/list without the CORS issues!

Interesting approach could be found here: How To Enlarge Your Columns With No Downtime by spaghettidba

If you try to enlarge this column with a straight “ALTER TABLE” command, you will have to wait for SQLServer to go through all the rows and write the new data type

ALTER TABLE tab_name ALTER COLUMN col_name new_larger_data_type;

To overcome this inconvenience, there is a magic column enlargement pill that your table can take, and it’s called Row Compression. (...) With Row Compression, your fixed size columns can use only the space needed by the smallest data type where the actual data fits.

When table is compressed at ROW level, then ALTER TABLE ALTER COLUMN is metadata only operation.

Suggestion 1 - extend the process pipe-line

You can use step-down as I describe in the links you refer to but you appear to use them in a wrong way.

Step down is not needed to scale images to ratios above 1:2 (typically, but not limited to). It is where you need to do a drastic down-scaling you need to split it up in two (and rarely, more) steps depending on content of the image (in particular where high-frequencies such as thin lines occur).

Every time you down-sample an image you will loose details and information. You cannot expect the resulting image to be as clear as the original.

If you are then scaling down the images in many steps you will loose a lot of information in total and the result will be poor as you already noticed.

Try with just one extra step, or at tops two.

Convolutions

In case of Photoshop notice that it applies a convolution after the image has been re-sampled, such as sharpen. It's not just bi-cubic interpolation that takes place so in order to fully emulate Photoshop we need to also add the steps Photoshop is doing (with the default setup).

For this example I will use my original answer that you refer to in your post, but I have added a sharpen convolution to it to improve quality as a post process (see demo at bottom).

Here is code for adding sharpen filter (it's based on a generic convolution filter - I put the weight matrix for sharpen inside it as well as a mix factor to adjust the pronunciation of the effect):

Usage:

sharpen(context, width, height, mixFactor);

The mixFactor is a value between [0.0, 1.0] and allow you do downplay the sharpen effect - rule-of-thumb: the less size the less of the effect is needed.

Function (based on this snippet):

function sharpen(ctx, w, h, mix) {

    var weights =  [0, -1, 0,  -1, 5, -1,  0, -1, 0],
        katet = Math.round(Math.sqrt(weights.length)),
        half = (katet * 0.5) |0,
        dstData = ctx.createImageData(w, h),
        dstBuff = dstData.data,
        srcBuff = ctx.getImageData(0, 0, w, h).data,
        y = h;
        
    while(y--) {

        x = w;

        while(x--) {

            var sy = y,
                sx = x,
                dstOff = (y * w + x) * 4,
                r = 0, g = 0, b = 0, a = 0;

            for (var cy = 0; cy < katet; cy++) {
                for (var cx = 0; cx < katet; cx++) {

                    var scy = sy + cy - half;
                    var scx = sx + cx - half;

                    if (scy >= 0 && scy < h && scx >= 0 && scx < w) {

                        var srcOff = (scy * w + scx) * 4;
                        var wt = weights[cy * katet + cx];

                        r += srcBuff[srcOff] * wt;
                        g += srcBuff[srcOff + 1] * wt;
                        b += srcBuff[srcOff + 2] * wt;
                        a += srcBuff[srcOff + 3] * wt;
                    }
                }
            }

            dstBuff[dstOff] = r * mix + srcBuff[dstOff] * (1 - mix);
            dstBuff[dstOff + 1] = g * mix + srcBuff[dstOff + 1] * (1 - mix);
            dstBuff[dstOff + 2] = b * mix + srcBuff[dstOff + 2] * (1 - mix)
            dstBuff[dstOff + 3] = srcBuff[dstOff + 3];
        }
    }

    ctx.putImageData(dstData, 0, 0);
}

The result of using this combination will be:

Depending on how much of the sharpening you want to add to the blend you can get result from default "blurry" to very sharp:

Suggestion 2 - low level algorithm implementation

If you want to get the best result quality-wise you'll need to go low-level and consider to implement for example this brand new algorithm to do this.

See Interpolation-Dependent Image Downsampling (2011) from IEEE.
Here is a link to the paper in full (PDF).

There are no implementations of this algorithm in JavaScript AFAIK of at this time so you're in for a hand-full if you want to throw yourself at this task.

The essence is (excerpts from the paper):

Abstract

An interpolation oriented adaptive down-sampling algorithm is proposed for low bit-rate image coding in this paper. Given an image, the proposed algorithm is able to obtain a low resolution image, from which a high quality image with the same resolution as the input image can be interpolated. Different from the traditional down-sampling algorithms, which are independent from the interpolation process, the proposed down-sampling algorithm hinges the down-sampling to the interpolation process. Consequently, the proposed down-sampling algorithm is able to maintain the original information of the input image to the largest extent. The down-sampled image is then fed into JPEG. A total variation (TV) based post processing is then applied to the decompressed low resolution image. Ultimately, the processed image is interpolated to maintain the original resolution of the input image. Experimental results verify that utilizing the downsampled image by the proposed algorithm, an interpolated image with much higher quality can be achieved. Besides, the proposed algorithm is able to achieve superior performance than JPEG for low bit rate image coding.

The computer "name" is resolved from the IP address by the underlying DNS (Domain Name System) library of the OS. There's no universal concept of a computer name across OSes, but DNS is generally available. If the computer name hasn't been configured so DNS can resolve it, it isn't available.

import java.net.InetAddress;
import java.net.UnknownHostException;

String hostname = "Unknown";

try
{
    InetAddress addr;
    addr = InetAddress.getLocalHost();
    hostname = addr.getHostName();
}
catch (UnknownHostException ex)
{
    System.out.println("Hostname can not be resolved");
}

Syntax:

• return the element's text content: $(selector).text()
• set the element's text content to content: $(selector).text(content)
• set the element's text content using a callback function: $(selector).text(function(index, curContent))

JQuery - Change the text of a span element

I am new to Angular but have found this to solve my issue:

<i class="icon-download" ng-click="showDetails = ! showDetails" ng-class="{'icon-upload': showDetails}"></i>

This will conditionally apply a class based on a var. It starts off with a icon-download as a default, the using ng-class, I check the status of showDetails if true/false and apply class icon-upload. Its working great.

Hope it helps.

This happens when a python extension (written in C) tries to access a memory beyond reach.

You can trace it in following ways.

• Add sys.settrace at the very first line of the code.

• Use gdb as described by Mark in this answer.. At the command prompt

  gdb python
  (gdb) run /path/to/script.py
  ## wait for segfault ##
  (gdb) backtrace
  ## stack trace of the c code
  

You can use ESCAPE:

WHERE columnName LIKE '%\%%' ESCAPE '\'

Just in case anybody finds the above insufficient, I ended up settling with this overload:

JsonConvert.SerializeObject(objToSerialize, Formatting.Indented, new Newtonsoft.Json.Converters.StringEnumConverter())

i know this is an old post, but i wanted to provide a JQuery plugin version and my code.

// Find the first occurrence of object in list, Similar to $.grep, but stops searching 
function findFirst(a,b){
var i; for (i = 0; i < a.length; ++i) { if (b(a[i], i)) return a[i]; } return undefined;
}

usage:

var product = $.findFirst(arrProducts, function(p) { return p.id == 10 });

You can use the multiprocessing module added in Python 2.6. You can use pools of processes and then get results asynchronously with:

apply_async(func[, args[, kwds[, callback]]])

E.g.:

from multiprocessing import Pool

def f(x):
    return x*x

if __name__ == '__main__':
    pool = Pool(processes=1)              # Start a worker processes.
    result = pool.apply_async(f, [10], callback) # Evaluate "f(10)" asynchronously calling callback when finished.

This is only one alternative. This module provides lots of facilities to achieve what you want. Also it will be really easy to make a decorator from this.

To keep this question current it is worth highlighting that AssemblyInformationalVersion is used by NuGet and reflects the package version including any pre-release suffix.

For example an AssemblyVersion of 1.0.3.* packaged with the asp.net core dotnet-cli

dotnet pack --version-suffix ci-7 src/MyProject

Produces a package with version 1.0.3-ci-7 which you can inspect with reflection using:

CustomAttributeExtensions.GetCustomAttribute<AssemblyInformationalVersionAttribute>(asm);

I highly recommend underscore or lo-dash libraries:

http://underscorejs.org/#range

(Almost completely compatible, apparently lodash runs quicker but underscore has better doco IMHO)

_.range([start], stop, [step])

Both libraries have bunch of very useful utilities.

From your code it would appear that you are trying to measure how long a computation took (as opposed to trying to figure out what the current time is).

In that case, you need to call currentTimeMillis before and after the computation, take the difference, and divide the result by 1000 to convert milliseconds to seconds.

cat("\f") may be easier to remember than cat("\014").

It works fine for me on Windows 10.

The code here will use AJAX to print text to an HTML5 document dynamically (Ajax code is similar to book Internet & WWW (Deitel)):

Javascript code:

var asyncRequest;    
function start(){
    try
    {
        asyncRequest = new XMLHttpRequest();
        asyncRequest.addEventListener("readystatechange", stateChange, false);
        asyncRequest.open('GET', '/Test', true);    //   /Test is url to Servlet!
        asyncRequest.send(null);
    }
    catch(exception)
   {
    alert("Request failed");
   }
}

function stateChange(){
if(asyncRequest.readyState == 4 && asyncRequest.status == 200)
    {
    var text = document.getElementById("text");         //  text is an id of a 
    text.innerHTML = asyncRequest.responseText;         //  div in HTML document
    }
}

window.addEventListener("load", start(), false);

Servlet java code:

public class Test extends HttpServlet{
@Override
public void doGet(HttpServletRequest req, HttpServletResponse resp)
    throws IOException{
        resp.setContentType("text/plain");
        resp.getWriter().println("Servlet wrote this! (Test.java)");
    }
}

HTML document

 <div id = "text"></div>

EDIT

I wrote answer above when I was new with web programming. I let it stand, but the javascript part should definitely be in jQuery instead, it is 10 times easier than raw javascript.

The line-continuation will fail if you have whitespace (spaces or tab characters[1]) after the backslash and before the newline. With no such whitespace, your example works fine for me:

$ cat test.sh
if ! fab --fabfile=.deploy/fabfile.py \
   --forward-agent \
   --disable-known-hosts deploy:$target; then
     echo failed
else
     echo succeeded
fi

$ alias fab=true; . ./test.sh
succeeded
$ alias fab=false; . ./test.sh
failed

Some detail promoted from the comments: the line-continuation backslash in the shell is not really a special case; it is simply an instance of the general rule that a backslash "quotes" the immediately-following character, preventing any special treatment it would normally be subject to. In this case, the next character is a newline, and the special treatment being prevented is terminating the command. Normally, a quoted character winds up included literally in the command; a backslashed newline is instead deleted entirely. But otherwise, the mechanism is the same. Most importantly, the backslash only quotes the immediately-following character; if that character is a space or tab, you just get a literal space or tab, and any subsequent newline remains unquoted.

[1] or carriage returns, for that matter, as Czechnology points out. Bash does not get along with Windows-formatted text files, not even in WSL. Or Cygwin, but at least their Bash port has added a set -o igncr option that you can set to make it carriage-return-tolerant.

Simple Example:

func method(arg: Bool, completion: (Bool) -> ()) {
    print("First line of code executed")
    // do stuff here to determine what you want to "send back".
    // we are just sending the Boolean value that was sent in "back"
    completion(arg)
}

How to use it:

method(arg: true, completion: { (success) -> Void in
    print("Second line of code executed")
    if success { // this will be equal to whatever value is set in this method call
          print("true")
    } else {
         print("false")
    }
})

Your regular expression [^a-zA-Z0-9]\s/g says match any character that is not a number or letter followed by a space.

Remove the \s and you should get what you are after if you want a _ for every special character.

var newString = str.replace(/[^A-Z0-9]/ig, "_");

That will result in hello_world___hello_universe

If you want it to be single underscores use a + to match multiple

var newString = str.replace(/[^A-Z0-9]+/ig, "_");

That will result in hello_world_hello_universe

Escape with a double backslash

R treats backslashes as escape values for character constants. (... and so do regular expressions. Hence the need for two backslashes when supplying a character argument for a pattern. The first one isn't actually a character, but rather it makes the second one into a character.) You can see how they are processed using cat.

y <- "double quote: \", tab: \t, newline: \n, unicode point: \u20AC"
print(y)
## [1] "double quote: \", tab: \t, newline: \n, unicode point: €"
cat(y)
## double quote: ", tab:    , newline: 
## , unicode point: €

Further reading: Escaping a backslash with a backslash in R produces 2 backslashes in a string, not 1

To use special characters in a regular expression the simplest method is usually to escape them with a backslash, but as noted above, the backslash itself needs to be escaped.

grepl("\\[", "a[b")
## [1] TRUE

To match backslashes, you need to double escape, resulting in four backslashes.

grepl("\\\\", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

The rebus package contains constants for each of the special characters to save you mistyping slashes.

library(rebus)
OPEN_BRACKET
## [1] "\\["
BACKSLASH
## [1] "\\\\"

For more examples see:

?SpecialCharacters

Your problem can be solved this way:

library(rebus)
grepl(OPEN_BRACKET, "a[b")

Form a character class

You can also wrap the special characters in square brackets to form a character class.

grepl("[?]", "a?b")
## [1] TRUE

Two of the special characters have special meaning inside character classes: \ and ^.

Backslash still needs to be escaped even if it is inside a character class.

grepl("[\\\\]", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

Caret only needs to be escaped if it is directly after the opening square bracket.

grepl("[ ^]", "a^b")  # matches spaces as well.
## [1] TRUE
grepl("[\\^]", "a^b") 
## [1] TRUE

rebus also lets you form a character class.

char_class("?")
## <regex> [?]

Use a pre-existing character class

If you want to match all punctuation, you can use the [:punct:] character class.

grepl("[[:punct:]]", c("//", "[", "(", "{", "?", "^", "$"))
## [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE

stringi maps this to the Unicode General Category for punctuation, so its behaviour is slightly different.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "[[:punct:]]")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

You can also use the cross-platform syntax for accessing a UGC.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "\\p{P}")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

Use \Q \E escapes

Placing characters between \\Q and \\E makes the regular expression engine treat them literally rather than as regular expressions.

grepl("\\Q.\\E", "a.b")
## [1] TRUE

rebus lets you write literal blocks of regular expressions.

literal(".")
## <regex> \Q.\E

Don't use regular expressions

Regular expressions are not always the answer. If you want to match a fixed string then you can do, for example:

grepl("[", "a[b", fixed = TRUE)
stringr::str_detect("a[b", fixed("["))
stringi::stri_detect_fixed("a[b", "[")

You are close you want to use @Html.Raw(str)

@Html.Encode takes strings and ensures that all the special characters are handled properly. These include characters like spaces.

Javascript using the onLoad() event, will wait for the page to be loaded before executing.

<body onload="somecode();" >

If you're using the jQuery framework's document ready function the code will load as soon as the DOM is loaded and before the page contents are loaded:

$(document).ready(function() {
    // jQuery code goes here
});

One solution is to set tis widget color property to Colors.transparent. For instance:

IconButton(
    icon: Image.asset("myImage.png",
        color: Colors.transparent,
    ),
    onPressed: () {},
),

for(map<string, pair<string,string> >::const_iterator it = myMap.begin();
    it != myMap.end(); ++it)
{
    std::cout << it->first << " " << it->second.first << " " << it->second.second << "\n";
}

In C++11, you don't need to spell out map<string, pair<string,string> >::const_iterator. You can use auto

for(auto it = myMap.cbegin(); it != myMap.cend(); ++it)
{
    std::cout << it->first << " " << it->second.first << " " << it->second.second << "\n";
}

Note the use of cbegin() and cend() functions.

Easier still, you can use the range-based for loop:

for(auto elem : myMap)
{
   std::cout << elem.first << " " << elem.second.first << " " << elem.second.second << "\n";
}

Here's one that looks very promising. It's a true combo - you see what you type. Has a cool feature I haven't seen elsewhere: paging results.

FlexBox

something like this:

f = open('data.txt', 'r')  
for line in f:  
   line =  line.split(';')  
   product = Product()  
   product.name = line[2] + '(' + line[1] + ')'  
   product.description = line[4]  
   product.price = '' #data is missing from file  
   product.save()  

f.close()  

Single line:

${str:${#str}-1:1}

Now:

echo "${str:${#str}-1:1}"

You can try to use btn-sm, btn-xs and btn-lg classes like this:

.btn-xl {
    padding: 10px 20px;
    font-size: 20px;
    border-radius: 10px;
}

JSFIDDLE DEMO

You can make use of Bootstrap .btn-group-justified css class. Or you can simply add:

.btn-xl {
    padding: 10px 20px;
    font-size: 20px;
    border-radius: 10px;
    width:50%;    //Specify your width here
}

I tried to follow it but my recyclerView began to stretch every item to a screen
I had to add next line after inflating for reach to goal

itemLayoutView.setLayoutParams(new RecyclerView.LayoutParams(RecyclerView.LayoutParams.MATCH_PARENT, RecyclerView.LayoutParams.WRAP_CONTENT));

I already added these params by xml but it didnot work correctly
and with this line all is ok

I've had luck with

There's always a goto statement, but I would recommend nesting an if with an inverse of the breaking condition.

Short And working Solution :

Follow Simple Steps :

Step 1 : Override onSaveInstanceState state in respective fragment. And remove super method from it.

@Override
public void onSaveInstanceState(Bundle outState) {
};

Step 2 : Use CommitAllowingStateLoss(); instead of commit(); while fragment operations.

fragmentTransaction.commitAllowingStateLoss();

Don't use doubles. You can lose some precision. Here's a general purpose function.

public static double round(double unrounded, int precision, int roundingMode)
{
    BigDecimal bd = new BigDecimal(unrounded);
    BigDecimal rounded = bd.setScale(precision, roundingMode);
    return rounded.doubleValue();
}

You can call it with

round(yourNumber, 3, BigDecimal.ROUND_HALF_UP);

"precision" being the number of decimal points you desire.

The language attribute has been deprecated for a long time, and should not be used.

When W3C was working on HTML5, they discovered all browsers have "text/javascript" as the default script type, so they standardized it to be the default value. Hence, you don't need type either.

For pages in XHTML 1.0 or HTML 4.01 omitting type is considered invalid. Try validating the following:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<script src="http://example.com/test.js"></script>
</head>
<body/>
</html>

You will be informed of the following error:

Line 4, Column 41: required attribute "type" not specified

So if you're a fan of standards, use it. It should have no practical effect, but, when in doubt, may as well go by the spec.

Thanks for the replies.
What I did was,
1. I install meinberg ntp software application on windows 7 pc. (softros ntp server is also possible.)
2. change raspberry pi ntp.conf file (for auto update date and time)

server xxx.xxx.xxx.xxx iburst
server 1.debian.pool.ntp.org iburst
server 2.debian.pool.ntp.org iburst
server 3.debian.pool.ntp.org iburst

3. If you want to make sure that date and time update at startup run this python script in rpi,

import os

try:
    client = ntplib.NTPClient()
    response = client.request('xxx.xxx.xxx.xxx', version=4)
    print "===================================="
    print "Offset : "+str(response.offset)
    print "Version : "+str(response.version)
    print "Date Time : "+str(ctime(response.tx_time))
    print "Leap : "+str(ntplib.leap_to_text(response.leap))
    print "Root Delay : "+str(response.root_delay)
    print "Ref Id : "+str(ntplib.ref_id_to_text(response.ref_id))
    os.system("sudo date -s '"+str(ctime(response.tx_time))+"'")
    print "===================================="
except:
    os.system("sudo date")
    print "NTP Server Down Date Time NOT Set At The Startup"
    pass

I found more info in raspberry pi forum.

PEAR: Mail worked for me sending email messages from Gmail. Also, the instructions: How to Send Email from a PHP Script Using SMTP Authentication (Using PEAR::Mail) helped greatly. Thanks, CMS!

The simplest workaround I've found looks like this:

* * * * * root su -l -c command

This example invokes su as root user and starts the shell with the user's full environment, including $PATH, set as if they were logged in. It works the same on different distros, is more reliable than sourcing .bashrc (which hasn't worked for me) and avoids hardcoding specific paths which can be a problem if you're providing an example or setup tool and don't know what distro or file layout on the user's system.

You can also specify the username after su if you want a different user than root, but you should probably leave the root parameter before su command since this ensures su has sufficient privileges to switch to any user you specify.

Maybe you mean like this? I like to make an object and use Format-Table:

> $array = @()
> $object = New-Object -TypeName PSObject
> $object | Add-Member -Name 'Name' -MemberType Noteproperty -Value 'Joe'
> $object | Add-Member -Name 'Age' -MemberType Noteproperty -Value 32
> $object | Add-Member -Name 'Info' -MemberType Noteproperty -Value 'something about him'
> $array += $object
> $array | Format-Table

Name                                                                        Age Info
----                                                                        --- ----
Joe                                                                          32  something about him

This will put all objects you have in the array in columns according to their properties.

Tip: Using -auto sizes the table better

> $array | Format-Table -Auto

Name Age Info
---- --- ----
Joe   32 something about him

You can also specify which properties you want in the table. Just separate each property name with a comma:

> $array | Format-Table Name, Age -Auto

Name Age
---- ---
Joe   32

The ideas provided above are good. For fast access (in case you would like to make a real time application) you could try the following:

//suppose you read an image from a file that is gray scale
Mat image = imread("Your path", CV_8UC1);
//...do some processing
uint8_t *myData = image.data;
int width = image.cols;
int height = image.rows;
int _stride = image.step;//in case cols != strides
for(int i = 0; i < height; i++)
{
    for(int j = 0; j < width; j++)
    {
        uint8_t val = myData[ i * _stride + j];
        //do whatever you want with your value
    }
}

Pointer access is much faster than the Mat.at<> accessing. Hope it helps!

For the following statement shared by Alex Booker in their answer

When the compiler encounters an expression-bodied property member, it essentially converts it to a getter like this:

Please see the following screenshot, it shows how this statement (using SharpLab link)

public string APIBasePath => Configuration.ToolsAPIBasePath;

converts to

public string APIBasePath
{
    get
    {
        return Configuration.ToolsAPIBasePath;
    }
}

Screenshot:

Using the GSON library:

import com.google.gson.Gson;
import com.google.common.reflect.TypeToken;
import java.lang.reclect.Type;

Use the following code:

Type mapType = new TypeToken<Map<String, Map>>(){}.getType();  
Map<String, String[]> son = new Gson().fromJson(easyString, mapType);

Another handy difference (in English where accents are uncommon) is that an InvariantCulture comparison compares the entire strings by case-insensitive first, and then if necessary (and requested) distinguishes by case after first comparing only on the distinct letters. (You can also do a case-insensitive comparison, of course, which won't distinguish by case.) Corrected: Accented letters are considered to be another flavor of the same letters and the string is compared first ignoring accents and then accounting for them if the general letters all match (much as with differing case except not ultimately ignored in a case-insensitive compare). This groups accented versions of the otherwise same word near each other instead of completely separate at the first accent difference. This is the sort order you would typically find in a dictionary, with capitalized words appearing right next to their lowercase equivalents, and accented letters being near the corresponding unaccented letter.

An ordinal comparison compares strictly on the numeric character values, stopping at the first difference. This sorts capitalized letters completely separate from the lowercase letters (and accented letters presumably separate from those), so capitalized words would sort nowhere near their lowercase equivalents.

InvariantCulture also considers capitals to be greater than lower case, whereas Ordinal considers capitals to be less than lowercase (a holdover of ASCII from the old days before computers had lowercase letters, the uppercase letters were allocated first and thus had lower values than the lowercase letters added later).

For example, by Ordinal: "0" < "9" < "A" < "Ab" < "Z" < "a" < "aB" < "ab" < "z" < "Á" < "Áb" < "á" < "áb"

And by InvariantCulture: "0" < "9" < "a" < "A" < "á" < "Á" < "ab" < "aB" < "Ab" < "áb" < "Áb" < "z" < "Z"

SQLite has hooks built-in for encryption which are not used in the normal distribution, but here are a few implementations I know of:

• SEE - The official implementation.
• wxSQLite - A wxWidgets style C++ wrapper that also implements SQLite's encryption.
• SQLCipher - Uses openSSL's libcrypto to implement.
• SQLiteCrypt - Custom implementation, modified API.
• botansqlite3 - botansqlite3 is an encryption codec for SQLite3 that can use any algorithms in Botan for encryption.
• sqleet - another encryption implementation, using ChaCha20/Poly1305 primitives. Note that wxSQLite mentioned above can use this as a crypto provider.

The SEE and SQLiteCrypt require the purchase of a license.

Disclosure: I created botansqlite3.

what is the exec function and its family.

The exec function family is all functions used to execute a file, such as execl, execlp, execle, execv, and execvp.They are all frontends for execve and provide different methods of calling it.

why is this function used

Exec functions are used when you want to execute (launch) a file (program).

and how does it work.

They work by overwriting the current process image with the one that you launched. They replace (by ending) the currently running process (the one that called the exec command) with the new process that has launched.

For more details: see this link.

You can easily do this though,

df.apply(LabelEncoder().fit_transform)

EDIT2:

In scikit-learn 0.20, the recommended way is

OneHotEncoder().fit_transform(df)

as the OneHotEncoder now supports string input. Applying OneHotEncoder only to certain columns is possible with the ColumnTransformer.

EDIT3:

Since this answer is over a year ago, and generated many upvotes (including a bounty), I should probably extend this further.

For inverse_transform and transform, you have to do a little bit of hack.

from collections import defaultdict
d = defaultdict(LabelEncoder)

With this, you now retain all columns LabelEncoder as dictionary.

# Encoding the variable
fit = df.apply(lambda x: d[x.name].fit_transform(x))

# Inverse the encoded
fit.apply(lambda x: d[x.name].inverse_transform(x))

# Using the dictionary to label future data
df.apply(lambda x: d[x.name].transform(x))

MOAR EDIT:

Using Neuraxle's FlattenForEach step, it's possible to do this as well to use the same LabelEncoder on all the flattened data at once:

FlattenForEach(LabelEncoder(), then_unflatten=True).fit_transform(df)

For using separate LabelEncoders depending for your columns of data, or if only some of your columns of data needs to be label-encoded and not others, then using a ColumnTransformer is a solution that allows for more control on your column selection and your LabelEncoder instances.

The CSS solution is: http://www.w3.org/TR/css3-multicol/

The browser support is exactly what you'd expect..

It works "everywhere" except Internet Explorer 9 or older: http://caniuse.com/multicolumn

ul {
    -moz-column-count: 4;
    -moz-column-gap: 20px;
    -webkit-column-count: 4;
    -webkit-column-gap: 20px;
    column-count: 4;
    column-gap: 20px;
}

See: http://jsfiddle.net/pdExf/

If IE support is required, you'll have to use JavaScript, for example:

http://welcome.totheinter.net/columnizer-jquery-plugin/

Another solution is to fallback to normal float: left for only IE. The order will be wrong, but at least it will look similar:

See: http://jsfiddle.net/NJ4Hw/

<!--[if lt IE 10]>
<style>
li {
    width: 25%;
    float: left
}
</style>
<![endif]-->

You could apply that fallback with Modernizr if you're already using it.

1st and important step is connect to your db:

psql -d yourDBName

2 step, grant privileges

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO userName;

Although, this may not be advisable.

If you want to get customer details, even when the user doesn’t create an account, but only makes an order, you could just query it, directly from the database.

Although, there may be performance issues, querying directly. But this surely works 100%.

You can search by post_id and meta_keys.

 global $wpdb; // Get the global $wpdb
 $order_id = {Your Order Id}

 $table = $wpdb->prefix . 'postmeta';
 $sql = 'SELECT * FROM `'. $table . '` WHERE post_id = '. $order_id;

        $result = $wpdb->get_results($sql);
        foreach($result as $res) {
            if( $res->meta_key == 'billing_phone'){
                   $phone = $res->meta_value;      // get billing phone
            }
            if( $res->meta_key == 'billing_first_name'){
                   $firstname = $res->meta_value;   // get billing first name
            }

            // You can get other values
            // billing_last_name
            // billing_email
            // billing_country
            // billing_address_1
            // billing_address_2
            // billing_postcode
            // billing_state

            // customer_ip_address
            // customer_user_agent

            // order_currency
            // order_key
            // order_total
            // order_shipping_tax
            // order_tax

            // payment_method_title
            // payment_method

            // shipping_first_name
            // shipping_last_name
            // shipping_postcode
            // shipping_state
            // shipping_city
            // shipping_address_1
            // shipping_address_2
            // shipping_company
            // shipping_country
        }

We eventually found the answer to this.

Excel will only respect the escaping of commas and speech marks if the column value is NOT preceded by a space. So generating the file without spaces like this...

Reference,Title,Description
1,"My little title","My description, which may contain ""speech marks"" and commas."
2,"My other little title","My other description, which may also contain ""speech marks"" and commas."

... fixed the problem. Hope this helps someone!

Short answer: No. myObj isn't the name of the object, it's the name of a variable holding a reference to the object - you could have any number of other variables holding a reference to the same object.

Now, if it's your program, then you make the rules: if you want to say that any given object will only be referenced by one variable, ever, and diligently enforce that in your code, then just set a property on the object with the name of the variable.

That said, i doubt what you're asking for is actually what you really want. Maybe describe your problem in a bit more detail...?

Pedantry: JavaScript doesn't have classes. someObject is a constructor function. Given a reference to an object, you can obtain a reference to the function that created it using the constructor property.

In response to the additional details you've provided:

The answer you're looking for can be found here: JavaScript Callback Scope (and in response to numerous other questions on SO - it's a common point of confusion for those new to JS). You just need to wrap the call to the object member in a closure that preserves access to the context object.

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

version: '2'
services:
  ubuntu:
        build: .
        container_name: ubuntu
        volumes:
            - ~/sph/laravel52:/www/laravel
        ports:
          - "80:80"
        tty: true

  CASE WHEN ISNUMERIC(QTY + 'e0') = 1 THEN CAST(QTY AS float) ELSE null END AS MyFloat
  CASE WHEN ISNUMERIC(QTY + 'e0') = 0 THEN QTY ELSE null END AS MyVarchar

• Two data types requires two columns
• Adding e0 fixes some ISNUMERIC issues (such as + - . and empty string being accepted)

I tried many scripts but they didn't work for all objects. You can't move clustered objects from one tablespace to another. For that you will have to use expdp, so I will suggest expdp is the best option to move all objects to a different tablespace.

Below is the command:

nohup expdp \"/ as sysdba\" DIRECTORY=test_dir DUMPFILE=users.dmp LOGFILE=users.log TABLESPACES=USERS &

You can check this link for details.

Short answer would be yes.

You can attach source using the properties for a project.

Go to Properties (for the Project) -> Java Build Path -> Libraries

Select the Library you want to attach source/javadoc for and then expand it, you'll see a list like so:

Source Attachment: (none)
Javadoc location: (none)
Native library location: (none)
Access rules: (No restrictions)

Select Javadoc location and then click Edit on the right hahnd side. It should be quite straight forward from there.

Good luck :)

append the revision using an "@" character:

svn copy http://src@REV http://dev

Or, use the -r [--revision] command line argument.

I'd download PuTTY and run a telnet session on port 80 to the webserver you want

HEAD /resource HTTP/1.1
Host: www.example.com

You could alternatively download Perl and try LWP's HEAD command. Or write your own script.

You can look at using dynamic modules and classes that can do the job. The only disadvantage is that it remains loaded in the app domain. But with the version of .NET framework being used, that could change. .NET 4.0 supports collectible dynamic assemblies and hence you can recreate the classes/types dynamically.

I suspect I'm not going to get a look-in on this question, but I am a very experienced programmer, and I hope some of the more open-minded readers will pay attention.

I believe that it suits object-oriented programming languages better for their value-returning procedures (VRPs) to be deterministic and pure.

'VRP' is the modern academic name for a function that is called as part of an expression, and has a return value that notionally replaces the call during evaluation of the expression. E.g. in a statement such as x = 1 + f(y) the function f is serving as a VRP.

'Deterministic' means that the result of the function depends only on the values of its parameters. If you call it again with the same parameter values, you are certain to get the same result.

'Pure' means no side-effects: calling the function does nothing except computing the result. This can be interpreted to mean no important side-effects, in practice, so if the VRP outputs a debugging message every time it is called, for example, that can probably be ignored.

Thus, if, in C#, your function is not deterministic and pure, I say you should make it a void function (in other words, not a VRP), and any value it needs to return should be returned in either an out or a ref parameter.

For example, if you have a function to delete some rows from a database table, and you want it to return the number of rows it deleted, you should declare it something like this:

public void DeleteBasketItems(BasketItemCategory category, out int count);

If you sometimes want to call this function but not get the count, you could always declare an overloading.

You might want to know why this style suits object-oriented programming better. Broadly, it fits into a style of programming that could be (a little imprecisely) termed 'procedural programming', and it is a procedural programming style that fits object-oriented programming better.

Why? The classical model of objects is that they have properties (aka attributes), and you interrogate and manipulate the object (mainly) through reading and updating those properties. A procedural programming style tends to make it easier to do this, because you can execute arbitrary code in between operations that get and set properties.

The downside of procedural programming is that, because you can execute arbitrary code all over the place, you can get some very obtuse and bug-vulnerable interactions via global variables and side-effects.

So, quite simply, it is good practice to signal to someone reading your code that a function could have side-effects by making it non-value returning.

It's not an exact duplicate (so far as I can find), but this is a common problem.

display:block is what you need. but you should read the spec to understand why.

Using webpack and scss:

Install font-awesome using npm (using the setup instructions on https://fontawesome.com/how-to-use)

npm install @fortawesome/fontawesome-free

Next, using the copy-webpack-plugin, copy the webfonts folder from node_modules to your dist folder during your webpack build process. (https://github.com/webpack-contrib/copy-webpack-plugin)

npm install copy-webpack-plugin

In webpack.config.js, configure copy-webpack-plugin. NOTE: The default webpack 4 dist folder is "dist", so we are copying the webfonts folder from node_modules to the dist folder.

const CopyWebpackPlugin = require('copy-webpack-plugin');

module.exports = {
    plugins: [
        new CopyWebpackPlugin([
            { from: './node_modules/@fortawesome/fontawesome-free/webfonts', to: './webfonts'}
        ])
    ]
}

Lastly, in your main.scss file, tell fontawesome where the webfonts folder has been copied to and import the SCSS files you want from node_modules.

$fa-font-path: "/webfonts"; // destination folder in dist
//Adapt the path to be relative to your main.scss file
@import "../node_modules/@fortawesome/fontawesome-free/scss/fontawesome";

//Include at least one of the below, depending on what icons you want.
//Adapt the path to be relative to your main.scss file
@import "../node_modules/@fortawesome/fontawesome-free/scss/brands";
@import "../node_modules/@fortawesome/fontawesome-free/scss/regular";
@import "../node_modules/@fortawesome/fontawesome-free/scss/solid";

@import "../node_modules/@fortawesome/fontawesome-free/scss/v4-shims"; // if you also want to use `fa v4`  like: `fa fa-address-book-o` 

and apply the following font-family to a desired region(s) in your html document where you want to use the fontawesome icons.

Example:

 body {
      font-family: 'Font Awesome 5 Free'; // if you use fa v5 (regular/solid)
      // font-family: 'Font Awesome 5 Brands'; // if you use fa v5 (brands)
    }

I would consider using something like https://www.bouncycastle.org/ It is a prebuilt library that allows you to encrypt whatever you like with a number of different Ciphers I understand that you only want to protect from snooping, but if you really want to protect the information, using Base64 won't actually protect you.

how to access iFrame parent page using jquery

window.parent.document.

jQuery is a library on top of JavaScript, not a complete replacement for it. You don't have to replace every last JavaScript expression with something involving $.

The following solution is:

• briefest. Somewhat similar to here. It's also minimal: The table in the DIV is orthogonal to your question.
• fastest: getElementById is called once at the outset. This may or may not suit your purposes.
• It uses pure JavaScript (i.e. without JQuery).
• It uses a button. Your taste may vary.
• extensible: it's ready to add more DIVs, sharing the code.

mydiv = document.getElementById("showmehideme");_x000D_
_x000D_
function showhide(d) {_x000D_
    d.style.display = (d.style.display !== "none") ? "none" : "block";_x000D_
}

#mydiv { background-color: #ddd; }

<button id="button" onclick="showhide(mydiv)">Show/Hide</button>_x000D_
<div id="showmehideme">_x000D_
    This div will show and hide on button click._x000D_
</div>

Try following int git bash

1.git add -u :/

2.git commit -m "your commit message"

3. git push -u origin master

Note:if you have not initialized your repo.

First of all

git init 

and follow above mentioned steps in order. This worked for me

For exe files, I suppose the differences are nearly unimportant.
But to start an exe you don't even need CALL.

When starting another batch it's a big difference,
as CALL will start it in the same window and the called batch has access to the same variable context.
So it can also change variables which affects the caller.

START will create a new cmd.exe for the called batch and without /b it will open a new window.
As it's a new context, variables can't be shared.

Differences

Using start /wait <prog>
- Changes of environment variables are lost when the <prog> ends
- The caller waits until the <prog> is finished

Using call <prog>
- For exe it can be ommited, because it's equal to just starting <prog>
- For an exe-prog the caller batch waits or starts the exe asynchronous, but the behaviour depends on the exe itself.
- For batch files, the caller batch continues, when the called <batch-file> finishes, WITHOUT call the control will not return to the caller batch

Addendum:

Using CALL can change the parameters (for batch and exe files), but only when they contain carets or percent signs.

call myProg param1 param^^2 "param^3" %%path%%

Will be expanded to (from within an batch file)

myProg param1 param2 param^^3 <content of path>

after passing the vector by reference

swap(vector[position],vector[otherPosition]);

will produce the expected result.

Mac OS Mojave

The accepted answer no longer works. When running the command xcode-select --install it tells you to use "Software Update" to install updates.

In this link is the updated method:

Open a Terminal and then:

cd /Library/Developer/CommandLineTools/Packages/
open macOS_SDK_headers_for_macOS_10.14.pkg

This will open an installation Wizard.

Update 12/2019

After updating to Mojave 10.15.1 it seems that using xcode-select --install works as intended.

Response you are getting is in object form i.e.

{ 
  "dstOffset" : 3600, 
  "rawOffset" : 36000, 
  "status" : "OK", 
  "timeZoneId" : "Australia/Hobart", 
  "timeZoneName" : "Australian Eastern Daylight Time" 
}

Replace below line of code :

List<Post> postsList = Arrays.asList(gson.fromJson(reader,Post.class))

with

Post post = gson.fromJson(reader, Post.class);

By default, a vagrant box doesn't have any ip address. In order to find the IP address, you simply assign the IP address in your Vagrantfile then call vagrant reload

If you just need to access a vagrant machine from only the host machine, setting up a "private network" is all you need. Either uncomment the appropriate line in a default Vagrantfile, or add this snippet. If you want your VM to appear at 172.30.1.5 it would be the following:

config.vm.network "private_network", ip: "172.30.1.5"

Learn more about private networks. https://www.vagrantup.com/docs/networking/private_network.html

If you need vagrant to be accessible outside your host machine, for instance for developing against a mobile device such as iOS or Android, you have to enable a public network you can use either static IP, such as 192.168.1.10, or DHCP.

config.vm.network "public_network", ip: "192.168.1.10"

Learn more about configuring a public network https://www.vagrantup.com/docs/networking/public_network.html

With hooks in React 16.8 onward, it's easy to do this with useEffect

I've created a CodeSandbox to demonstrate this.

useEffect(() => {
  // code to be run when state variables in
  // dependency array changes
}, [stateVariables, thatShould, triggerChange])

Basically, useEffect synchronises with state changes and this can be used to render the canvas

import React, { useState, useEffect, useRef } from "react";
import { Stage, Shape } from "@createjs/easeljs";
import "./styles.css";

export default function App() {
  const [rows, setRows] = useState(10);
  const [columns, setColumns] = useState(10);
  let stage = useRef()

  useEffect(() => {
    stage.current = new Stage("canvas");
    var rectangles = [];
    var rectangle;
    //Rows
    for (var x = 0; x < rows; x++) {
      // Columns
      for (var y = 0; y < columns; y++) {
        var color = "Green";
        rectangle = new Shape();
        rectangle.graphics.beginFill(color);
        rectangle.graphics.drawRect(0, 0, 32, 44);
        rectangle.x = y * 33;
        rectangle.y = x * 45;

        stage.current.addChild(rectangle);

        var id = rectangle.x + "_" + rectangle.y;
        rectangles[id] = rectangle;
      }
    }
    stage.current.update();
  }, [rows, columns]);

  return (
    <div>
      <div className="canvas-wrapper">
        <canvas id="canvas" width="400" height="300"></canvas>
        <p>Rows: {rows}</p>
        <p>Columns: {columns}</p>
      </div>
      <div className="array-form">
        <form>
          <label>Number of Rows</label>
          <select
            id="numRows"
            value={rows}
            onChange={(e) => setRows(e.target.value)}
          >
            {getOptions()}
          </select>
          <label>Number of Columns</label>
          <select
            id="numCols"
            value={columns}
            onChange={(e) => setColumns(e.target.value)}
          >
            {getOptions()}
          </select>
        </form>
      </div>
    </div>
  );
}

const getOptions = () => {
  const options = [1, 2, 5, 10, 12, 15, 20];
  return (
    <>
      {options.map((option) => (
        <option key={option} value={option}>
          {option}
        </option>
      ))}
    </>
  );
};

 <script src="~/fileupload/fileinput.min.js"></script>
 <link href="~/fileupload/fileinput.min.css" rel="stylesheet" />

Download above files named fileinput add the path i your index page.

<div class="col-sm-9 col-lg-5" style="margin: 0 0 0 8px;">
<input id="uploadFile1" name="file" type="file" class="file-loading"       
 `enter code here`accept=".pdf" multiple>
</div>

<script>
        $("#uploadFile1").fileinput({
            autoReplace: true,
            maxFileCount: 5
        });
</script>

if you are using for certain text field then use the class

<style>
  .inputForm{
      border-radius:5px;
      -moz-border-radius:5px;
      -webkit-border-radius:5px;
   }
</style>

and in html code use

 <input type="text" class="inputForm">

or if u want to do this for all the input type text field means use

<style>
    input[type="text"]{
      border-radius:5px;
      -moz-border-radius:5px;
      -webkit-border-radius:5px;
    }
 </style>

and in html code

<input type="text" name="name">

There's a simple way to this in any C-like language. The style is not Pythonic but works with pure Python:

def remove_html_markup(s):
    tag = False
    quote = False
    out = ""

    for c in s:
            if c == '<' and not quote:
                tag = True
            elif c == '>' and not quote:
                tag = False
            elif (c == '"' or c == "'") and tag:
                quote = not quote
            elif not tag:
                out = out + c

    return out

The idea based in a simple finite-state machine and is detailed explained here: http://youtu.be/2tu9LTDujbw

You can see it working here: http://youtu.be/HPkNPcYed9M?t=35s

PS - If you're interested in the class(about smart debugging with python) I give you a link: https://www.udacity.com/course/software-debugging--cs259. It's free!

$('#myForm').submit(function() {
    var c = confirm("Click OK to continue?");
    return c; //you can just return c because it will be true or false
});

The answer is just 1 line code:

let randomNumber = arc4random_uniform(8999) + 1000 //for 4 digit random number
let randomNumber = arc4random_uniform(899999999) + 100000000 //for 9 digit random number
let randomNumber = arc4random_uniform(89) + 10    //for 2 digit random number
let randomNumber = arc4random_uniform(899) + 100  //for 3 digit random number

The alternate solution is:

    func generateRandomNumber(numDigits: Int) -> Int{
    var place = 1
    var finalNumber = 0;
    var finanum = 0;
    for var i in 0 ..< numDigits {
        place *= 10
        let randomNumber = arc4random_uniform(10)         
        finalNumber += Int(randomNumber) * place
        finanum = finalNumber / 10
           i += 1
    }
    return finanum
}

Although the drawback is that number cannot start from 0.

A bit late but I used jQuery ajax method. But I did not want to send a request every second if I haven't got the response back from the last request, so I did this.

function request(){
            if(response == true){
                // This makes it unable to send a new request 
                // unless you get response from last request
                response = false;
                var req = $.ajax({
                    type:"post",
                    url:"request-handler.php",
                    data:{data:"Hello World"}
                });

                req.done(function(){
                    console.log("Request successful!");

                    // This makes it able to send new request on the next interval
                    response = true;
                });
            }

            setTimeout(request(),1000);
        }

        request();

It may be that "watch" is not what you want. You probably want to ask for help in solving your problem, not in implementing your solution! :)

If your real goal is to trigger actions based on what's seen from the tail command, then you can do that as part of the tail itself. Instead of running "periodically", which is what watch does, you can run your code on demand.

#!/bin/sh

tail -F /var/log/somelogfile | while read line; do
  if echo "$line" | grep -q '[Ss]ome.regex'; then
    # do your stuff
  fi
done

Note that tail -F will continue to follow a log file even if it gets rotated by newsyslog or logrotate. You want to use this instead of the lower-case tail -f. Check man tail for details.

That said, if you really do want to run a command periodically, the other answers provided can be turned into a short shell script:

#!/bin/sh
if [ -z "$2" ]; then
  echo "Usage: $0 SECONDS COMMAND" >&2
  exit 1
fi

SECONDS=$1
shift 1
while sleep $SECONDS; do
  clear
  $*
done

What is DATA ACCESS OBJECT (DAO) -

It is a object/interface, which is used to access data from database of data storage.

WHY WE USE DAO:

it abstracts the retrieval of data from a data resource such as a database. The concept is to "separate a data resource's client interface from its data access mechanism."

The problem with accessing data directly is that the source of the data can change. Consider, for example, that your application is deployed in an environment that accesses an Oracle database. Then it is subsequently deployed to an environment that uses Microsoft SQL Server. If your application uses stored procedures and database-specific code (such as generating a number sequence), how do you handle that in your application? You have two options:

• Rewrite your application to use SQL Server instead of Oracle (or add conditional code to handle the differences), or
• Create a layer inbetween your application logic and the data access

Its in all referred as DAO Pattern, It consist of following:

• Data Access Object Interface - This interface defines the standard operations to be performed on a model object(s).
• Data Access Object concrete class -This class implements above interface. This class is responsible to get data from a datasource which can be database / xml or any other storage mechanism.
• Model Object or Value Object - This object is simple POJO containing get/set methods to store data retrieved using DAO class.

Please check this example, This will clear things more clearly.

Example
I assume this things must have cleared your understanding of DAO up to certain extend.

The best way is to use a List within a List:

List<List<String>> listOfLists = new ArrayList<List<String>>();  

select 1 from table

will return a column of 1's for every row in the table. You could use it with a where statement to check whether you have an entry for a given key, as in:

if exists(select 1 from table where some_column = 'some_value')

What your friend was probably saying is instead of making bulk selects with select * from table, you should specify the columns that you need precisely, for two reasons:

1) performance & you might retrieve more data than you actually need.

2) the query's user may rely on the order of columns. If your table gets updated, the client will receive columns in a different order than expected.

There is no standard, so there is no guarantee. With that said, its common for the sitemap to be self labeled and on the root, like this:

example.com/sitemap.xml

Case is sensitive on some servers, so keep that in mind. If its not there, look in the robots file on the root:

example.com/robots.txt

If you don't see it listed in the robots file head to Google and search this:

site:example.com filetype:xml

This will limit the results to XML files on your target domain. At this point its trial-and-error and based on the specifics of the website you are working with. If you get several pages of results from the Google search phrase above then try to limit the results further:

filetype:xml site:example.com inurl:sitemap

or

filetype:xml site:example.com inurl:products

If you still can't find it you can right-click > "View Source" and do a search (aka: "control find" or Ctrl + F) for .xml to see if there is a reference to it in the code.

In the Terminal app, Preference >> Profiles tab.

Select the Shell tab on the right.

You can choose Never Ask before closing to suppress the warning.

As Ennui mentioned, IE 10 supports the -ms prefixed version of Flexbox (IE 11 supports it unprefixed). The errors I can see in your code are:

• You should have display: -ms-flexbox instead of display: -ms-flex
• I think you should specify all 3 flex values, like flex: 0 1 auto to avoid ambiguity

So the final updated code is...

.flexbox form {
    display: -webkit-flex;
    display: -moz-flex;
    display: -ms-flexbox;
    display: -o-flex;
    display: flex;

    /* Direction defaults to 'row', so not really necessary to specify */
    -webkit-flex-direction: row;
    -moz-flex-direction: row;
    -ms-flex-direction: row;
    -o-flex-direction: row;
    flex-direction: row;
}

.flexbox form input[type=submit] {
    width: 31px;
}

.flexbox form input[type=text] {
    width: auto;

    /* Flex should have 3 values which is shorthand for 
       <flex-grow> <flex-shrink> <flex-basis> */
    -webkit-flex: 1 1 auto;
    -moz-flex: 1 1 auto;
    -ms-flex: 1 1 auto;
    -o-flex: 1 1 auto;
    flex: 1 1 auto;

    /* I don't think you need 'display: flex' on child elements * /
    display: -webkit-flex;
    display: -moz-flex;
    display: -ms-flex;
    display: -o-flex;
    display: flex;
    /**/
}

What you are passing to JSON.parse method must be a valid JSON after removing the wrapping quotes for string.

so something is not a valid JSON but "something" is.

A valid JSON is -

JSON = null
    /* boolean literal */
    or true or false
    /* A JavaScript Number Leading zeroes are prohibited; a decimal point must be followed by at least one digit.*/
    or JSONNumber
    /* Only a limited sets of characters may be escaped; certain control characters are prohibited; the Unicode line separator (U+2028) and paragraph separator (U+2029) characters are permitted; strings must be double-quoted.*/
    or JSONString

    /* Property names must be double-quoted strings; trailing commas are forbidden. */
    or JSONObject
    or JSONArray

Examples -

JSON.parse('{}'); // {}
JSON.parse('true'); // true
JSON.parse('"foo"'); // "foo"
JSON.parse('[1, 5, "false"]'); // [1, 5, "false"]
JSON.parse('null'); // null 
JSON.parse("'foo'"); // error since string should be wrapped by double quotes

You may want to look JSON.

"Virtual" means that the method may be overridden in subclasses, but has an directly-callable implementation in the base class. "Pure virtual" means it is a virtual method with no directly-callable implementation. Such a method must be overridden at least once in the inheritance hierarchy -- if a class has any unimplemented virtual methods, objects of that class cannot be constructed and compilation will fail.

@quark points out that pure-virtual methods can have an implementation, but as pure-virtual methods must be overridden, the default implementation can't be directly called. Here is an example of a pure-virtual method with a default:

#include <cstdio>

class A {
public:
    virtual void Hello() = 0;
};

void A::Hello() {
    printf("A::Hello\n");
}

class B : public A {
public:
    void Hello() {
        printf("B::Hello\n");
        A::Hello();
    }
};

int main() {
    /* Prints:
           B::Hello
           A::Hello
    */
    B b;
    b.Hello();
    return 0;
}

According to comments, whether or not compilation will fail is compiler-specific. In GCC 4.3.3 at least, it won't compile:

class A {
public:
    virtual void Hello() = 0;
};

int main()
{
    A a;
    return 0;
}

Output:

$ g++ -c virt.cpp 
virt.cpp: In function ‘int main()’:
virt.cpp:8: error: cannot declare variable ‘a’ to be of abstract type ‘A’
virt.cpp:1: note:   because the following virtual functions are pure within ‘A’:
virt.cpp:3: note:   virtual void A::Hello()

My best approach is:

var item = {...}
var items = [{id:2}, {id:2}, {id:2}];

items[items.findIndex(el => el.id === item.id)] = item;

Reference for findIndex

And in case you don't want to replace with new object, but instead to copy the fields of item, you can use Object.assign:

Object.assign(items[items.findIndex(el => el.id === item.id)], item)

as an alternative with .map():

Object.assign(items, items.map(el => el.id === item.id? item : el))

Functional approach:

Don't modify the array, use a new one, so you don't generate side effects

const updatedItems = items.map(el => el.id === item.id ? item : el)

I don't think zip returns a list. zip returns a generator. You have got to do list(zip(a, b)) to get a list of tuples.

x = [1, 2, 3]
y = [4, 5, 6]
zipped = zip(x, y)
list(zipped)

Try with this:

public static boolean userNameValidation(String name){

return name.matches("(?i)(^[a-z])((?![? .,'-]$)[ .]?[a-z]){3,24}$");
}

Angular syntax is to use the : operator to perform the equivalent of an if modifier

<div ng-class="{ 'clearfix' : (row % 2) == 0 }">

Add clearfix class to even rows. Nonetheless, expression could be anything we can have in normal if condition and it should evaluate to either true or false.

Cents? If you're calculationg money values you really shouldn't use float values. Money is actually countable values. The cents or pennys etc. could be considered the two (or whatever) least significant digits of an integer. You could store, and calculate money values as integers and divide by 100 (e.g. place dot or comma two before the two last digits). Using float's can lead to strange rounding errors...

Anyway, if your epsilon is supposed to define the accuracy, it looks a bit too small (too accurate)...

There is a much simpler method to execute a function at the end of the resize than calculate the delta time between two calls, simply do it like this :

var resizeId;
$(window).resize(function() {
    clearTimeout(resizeId);
    resizeId = setTimeout(resizedEnded, 500);
});

function resizedEnded(){
    ...
}

And the equivalent for Angular2 :

private resizeId;
@HostListener('window:resize', ['$event'])
onResized(event: Event) {
  clearTimeout(this.resizeId);
  this.resizeId = setTimeout(() => {
    // Your callback method here.
  }, 500);
}

For the angular method, use the () => { } notation in the setTimeout to preserve the scope, otherwise you will not be able to make any function calls or use this.

Just wanted to share a curiosity:

when using the onkeydown event to activate a JS method, the charcode for that event is NOT the same as the one you get with onkeypress!

For instance the numpad keys will return the same charcodes as the number keys above the letter keys when using onkeypress, but NOT when using onkeydown !

Took me quite a few seconds to figure out why my script which checked for certain charcodes failed when using onkeydown!

Demo: https://www.w3schools.com/code/tryit.asp?filename=FMMBXKZLP1MK

and yes. I do know the definition of the methods are different.. but the thing that is very confusing is that in both methods the result of the event is retrieved using event.keyCode.. but they do not return the same value.. not a very declarative implementation.

3 things you have to do, if you are doing it locally:

in php.ini or php.cfg of your php installation

post_max_size=500M

upload_max_filesize=500M

memory_limit=900M

or set other values. Restart Apache.

OR

Use php big dump tool its best ever i have seen. its free and opensource

I searched on the internet and found a simple jquery code to handle this problem. In my side, it was solved and worked on ie 9.

$("input[placeholder]").each(function () {
        var $this = $(this);
        if($this.val() == ""){
            $this.val($this.attr("placeholder")).focus(function(){
                if($this.val() == $this.attr("placeholder")) {
                    $this.val("");
                }
            }).blur(function(){
                if($this.val() == "") {
                    $this.val($this.attr("placeholder"));
                }
            });
        }
    });

There are many excellent solutions above. IMO, if your break conditions are exceptions, you can use try-catch:

try{  
    for (var i in set1) {
        for (var j in set2) {
            for (var k in set3) {
                throw error;
            }
        }
    }
}catch (error) {

}

Git now ships with a subcommand 'git request-pull' [-p] <start> <url> [<end>]

You can see the docs here

You may find this useful but it is not exactly the same as GitHub's feature.

for k, v in mydict.iteritems():
    if v is None:
        mydict[k] = ''

In a more general case, e.g. if you were adding or removing keys, it might not be safe to change the structure of the container you're looping on -- so using items to loop on an independent list copy thereof might be prudent -- but assigning a different value at a given existing index does not incur any problem, so, in Python 2.any, it's better to use iteritems.

In Python3 however the code gives AttributeError: 'dict' object has no attribute 'iteritems' error. Use items() instead of iteritems() here.

Refer to this post.

from (
    select count(m.owner_id) as qty, o.name
    from transport t,owner o,motorbike m
    where t.type='motobike' and o.owner_id=m.owner_id
        and t.type_id=m.motorbike_id
    group by m.owner_id

    union all

group by name

Very easy:

var stringArr = dataTable.Rows[0].ItemArray.Select(x => x.ToString()).ToArray();

Where DataRow.ItemArray property is an array of objects containing the values of the row for each columns of the data table.

As everyone pointed out even though having multiple template directives in a single element works in angular 1.x it is not allowed in Angular 2. you can find more info from here : https://github.com/angular/angular/issues/7315

2016 angular 2 beta

solution is to use the <template> as a placeholder, so the code goes like this

<template *ngFor="let nav_link of defaultLinks"  >
   <li *ngIf="nav_link.visible">
       .....
   </li>
</template>

but for some reason above does not work in 2.0.0-rc.4 in that case you can use this

<template ngFor let-nav_link [ngForOf]="defaultLinks" >
   <li *ngIf="nav_link.visible">
       .....
   </li> 
</template>

Updated Answer 2018

With updates, right now in 2018 angular v6 recommend to use <ng-container> instead of <template>

so here is the updated answer.

<ng-container *ngFor="let nav_link of defaultLinks" >
   <li *ngIf="nav_link.visible">
       .....
   </li> 
</ng-container>

Well, as others have stated, ambiguity in type is the issue. So the answer is no, C# doesn't let that happen because it's a strongly typed language, and it deals only with compile time known types. The compiler could have been designed to infer it as of type object, but the designers chose to avoid the extra complexity (in C# null has no type).

One alternative is

var foo = new { }; //anonymous type

Again note that you're initializing to a compile time known type, and at the end its not null, but anonymous object. It's only a few lines shorter than new object(). You can only reassign the anonymous type to foo in this one case, which may or may not be desirable.

Initializing to null with type not being known is out of question.

Unless you're using dynamic.

dynamic foo = null;
//or
var foo = (dynamic)null; //overkill

Of course it is pretty useless, unless you want to reassign values to foo variable. You lose intellisense support as well in Visual Studio.

Lastly, as others have answered, you can have a specific type declared by casting;

var foo = (T)null;

So your options are:

//initializes to non-null; I like it; cant be reassigned a value of any type
var foo = new { }; 

//initializes to non-null; can be reassigned a value of any type
var foo = new object();

//initializes to null; dangerous and finds least use; can be reassigned a value of any type
dynamic foo = null;
var foo = (dynamic)null;

//initializes to null; more conventional; can be reassigned a value of any type
object foo = null;

//initializes to null; cannot be reassigned a value of any type
var foo = (T)null;

Hans and DarkDust answer covered i386/i686 and amd64/x86_64, so there's no sense in revisiting them. This answer will focus on X32, and provide some info learned after a X32 port.

x32 is an ABI for amd64/x86_64 CPUs using 32-bit integers, longs and pointers. The idea is to combine the smaller memory and cache footprint from 32-bit data types with the larger register set of x86_64. (Reference: Debian X32 Port page).

x32 can provide up to about 30% reduction in memory usage and up to about 40% increase in speed. The use cases for the architecture are:

• vserver hosting (memory bound)
• netbooks/tablets (low memory, performance)
• scientific tasks (performance)

x32 is a somewhat recent addition. It requires kernel support (3.4 and above), distro support (see below), libc support (2.11 or above), and GCC 4.8 and above (improved address size prefix support).

For distros, it was made available in Ubuntu 13.04 or Fedora 17. Kernel support only required pointer to be in the range from 0x00000000 to 0xffffffff. From the System V Application Binary Interface, AMD64 (With LP64 and ILP32 Programming Models), Section 10.4, p. 132 (its the only sentence):

10.4 Kernel Support
Kernel should limit stack and addresses returned from system calls between 0x00000000 to 0xffffffff.

When booting a kernel with the support, you must use syscall.x32=y option. When building a kernel, you must include the CONFIG_X86_X32=y option. (Reference: Debian X32 Port page and X32 System V Application Binary Interface).

Here is some of what I have learned through a recent port after the Debian folks reported a few bugs on us after testing:

• the system is a lot like X86
• the preprocessor defines __x86_64__ (and friends) and __ILP32__, but not __i386__/__i686__ (and friends)
• you cannot use __ILP32__ alone because it shows up unexpectedly under Clang and Sun Studio
• when interacting with the stack, you must use the 64-bit instructions pushq and popq
• once a register is populated/configured from 32-bit data types, you can perform the 64-bit operations on them, like adcq
• be careful of the 0-extension that occurs on the upper 32-bits.

If you are looking for a test platform, then you can use Debian 8 or above. Their wiki page at Debian X32 Port has all the information. The 3-second tour: (1) enable X32 in the kernel at boot; (2) use debootstrap to install the X32 chroot environment, and (3) chroot debian-x32 to enter into the environment and test your software.

Mike Flynn's version did not work for me. Renaming C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\Microsoft.TeamFoundation.Git.Provider.dll worked for me.

If you want to detach existing object follow @Slauma's advice. If you want to load objects without tracking changes use:

var data = context.MyEntities.AsNoTracking().Where(...).ToList();

As mentioned in comment this will not completely detach entities. They are still attached and lazy loading works but entities are not tracked. This should be used for example if you want to load entity only to read data and you don't plan to modify them.

We can simply use

async: false 

This will do your need.

$ENV{FOO} for usage, where FOO is being picked up from the environment variable. otherwise use as ${FOO}, where FOO is some other variable. For setting, SET(FOO "foo") would be used in CMake.

routes.MapRoute(
                "Area",
                "{area}/",
                new { area = "AreaZ", controller = "ControlerX ", action = "ActionY " }
            );

Have you tried that ?

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

You can use this code:

int count;
            try {
                URL url = new URL(f_url[0]);
                URLConnection conection = url.openConnection();
                conection.setConnectTimeout(TIME_OUT);
                conection.connect();
                // Getting file length
                int lenghtOfFile = conection.getContentLength();
                // Create a Input stream to read file - with 8k buffer
                InputStream input = new BufferedInputStream(url.openStream(),
                        8192);
                // Output stream to write file
                OutputStream output = new FileOutputStream(
                        "/sdcard/9androidnet.jpg");

                byte data[] = new byte[1024];
                long total = 0;
                while ((count = input.read(data)) != -1) {
                    total += count;
                    // publishing the progress....
                    // After this onProgressUpdate will be called
                    publishProgress("" + (int) ((total * 100) / lenghtOfFile));
                    // writing data to file
                    output.write(data, 0, count);
                }
                // flushing output
                output.flush();
                // closing streams
                output.close();
                input.close();
            } catch (SocketTimeoutException e) {
                connectionTimeout=true;
            } catch (Exception e) {
                Log.e("Error: ", e.getMessage());
            }

The equivalent in a more modern and browser compatible way, using modern addEventListener APIs.

window.addEventListener('beforeunload', (event) => {
  // Cancel the event as stated by the standard.
  event.preventDefault();
  // Chrome requires returnValue to be set.
  event.returnValue = '';
});

Maybe it's too late, but in version 2.1 of TypeScript you can use key of like this:

interface Person {
    name: string;
    age: number;
    location: string;
}

type K1 = keyof Person; // "name" | "age" | "location"
type K2 = keyof Person[];  // "length" | "push" | "pop" | "concat" | ...
type K3 = keyof { [x: string]: Person };  // string

Source: https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-1.html#keyof-and-lookup-types

Another approach is to add a toString() method to your Car class and just let the toString() method of ArrayList do all the work.

@Override
public String toString()
{
    return "Car{" +
            "make=" + make +
            ", registration='" + registration + '\'' +
            '}';
}

You don't get one car per line in the output, but it is quick and easy if you just want to see what is in the array.

List<Car> cars = c1.getAll();
System.out.println(cars);

Output would be something like this:

[Car{make=FORD, registration='ABC 123'},
Car{make=TOYOTA, registration='ZYZ 999'}]

@Entity
@NamedQuery(name = "Customer.listUniqueNames", 
            query = "SELECT DISTINCT c.name FROM Customer c")
public class Customer {
        ...

        private String name;

        public static List<String> listUniqueNames() {
             return = getEntityManager().createNamedQuery(
                   "Customer.listUniqueNames", String.class)
                   .getResultList();
        }
}

PHP's preg_replace example:

$str = "motttherbb fffaaattther";
$str = preg_replace("/([a-z])\\1/", "", $str);
echo $str;

Here [a-z] hits the character, () then allows it to be used with \\1 backreference which tries to match another same character (note this is targetting 2 consecutive characters already), thus:

mother father

If you did:

$str = preg_replace("/([a-z])\\1{2}/", "", $str);

that would be erasing 3 consecutive repeated characters, outputting:

moherbb her

Although it's a long time after this question is being asked since I was searching so much for the same problem and couldn't find the extant solutions helpful, I write what fixed my trouble for anyone with the same issue: The point is, Jupyter should be installed in your virtual environment, meaning, after activating the tensorflow environment, run the following in the command prompt (in tensorflow virtual environment):

conda install jupyter
jupyter notebook

and then the jupyter will pop up.

another example, split on non alpha-numeric and keep the separators

import re
a = "foo,bar@candy*ice%cream"
re.split('([^a-zA-Z0-9])',a)

output:

['foo', ',', 'bar', '@', 'candy', '*', 'ice', '%', 'cream']

explanation

re.split('([^a-zA-Z0-9])',a)

() <- keep the separators
[] <- match everything in between
^a-zA-Z0-9 <-except alphabets, upper/lower and numbers.

As others have also mentioned, this can be readily solved by adding the following to the onCreate() of the Activity:

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        getWindow().setStatusBarColor(ContextCompat.getColor(this, R.color.primary_dark));
    }

However, the important point I want to add here is that in some cases, even the above does not change the status bar color. For example, when using MikePenz library for Navigation Drawer, it implicityly overrides the status bar color, so that you need to manually add the following for it to work:

.withStatusBarColorRes(R.color.status_bar_color)

When an Abstract Class Implements an Interface

In the section on Interfaces, it was noted that a class that implements an interface must implement all of the interface's methods. It is possible, however, to define a class that does not implement all of the interface's methods, provided that the class is declared to be abstract. For example,

abstract class X implements Y {   
    // implements all but one method of Y
}

class XX extends X {   
    // implements the remaining method in Y 
} 

In this case, class X must be abstract because it does not fully implement Y, but class XX does, in fact, implement Y.

Reference: http://docs.oracle.com/javase/tutorial/java/IandI/abstract.html

it was the update version of Codemwnci. his code is quite fine and works great except the error message. To avoid error you must change the condition statement.

  // Listen for changes in the text
textField.getDocument().addDocumentListener(new DocumentListener() {
  public void changedUpdate(DocumentEvent e) {
    warn();
  }
  public void removeUpdate(DocumentEvent e) {
    warn();
  }
  public void insertUpdate(DocumentEvent e) {
    warn();
  }

  public void warn() {
     if (textField.getText().length()>0){
       JOptionPane.showMessageDialog(null,
          "Error: Please enter number bigger than 0", "Error Massage",
          JOptionPane.ERROR_MESSAGE);
     }
  }
});

Pointer arithmetic is not allowed on void* pointers.

redirect with query string

 $('#results').on('click', '.item', function () {
                    var NestId = $(this).data('id');
                   // var url = '@Url.Action("Details", "Artists",new { NestId = '+NestId+'  })'; 
                    var url = '@ Url.Content("~/Artists/Details?NestId =' + NestId + '")'
                    window.location.href = url; 
                })

You'd need to make the enum expose value somehow, e.g.

public enum Tax {
    NONE(0), SALES(10), IMPORT(5);

    private final int value;
    private Tax(int value) {
        this.value = value;
    }

    public int getValue() {
        return value;
    }
}

...

public int getTaxValue() {
    Tax tax = Tax.NONE; // Or whatever
    return tax.getValue();
}

(I've changed the names to be a bit more conventional and readable, btw.)

This is assuming you want the value assigned in the constructor. If that's not what you want, you'll need to give us more information.

1.get all tables and views from information_schema.tables, include those of information_schema and pg_catalog.

select * from information_schema.tables

2.get tables and views belong certain schema

select * from information_schema.tables
    where table_schema not in ('information_schema', 'pg_catalog')

3.get tables only(almost \dt)

select * from information_schema.tables
    where table_schema not in ('information_schema', 'pg_catalog') and
    table_type = 'BASE TABLE'

You must define Full-Text-Index on all tables in database where you require to use a query with CONTAINS which will take sometime.

Instead you can use the LIKE which will give you instant results without the need to adjust any settings for the tables.

Example:

SELECT * FROM ChartOfAccounts WHERE AccountName LIKE '%Tax%'

The same result obtained with CONTAINS can be obtained with LIKE.
