There are basically two major pitfalls people stumble in with floating-point numbers.

1. The problem of scale. Each FP number has an exponent which determines the overall “scale” of the number so you can represent either really small values or really larges ones, though the number of digits you can devote for that is limited. Adding two numbers of different scale will sometimes result in the smaller one being “eaten” since there is no way to fit it into the larger scale.

   PS> $a = 1; $b = 0.0000000000000000000000001
   PS> Write-Host a=$a b=$b
   a=1 b=1E-25
   PS> $a + $b
   1
   

   As an analogy for this case you could picture a large swimming pool and a teaspoon of water. Both are of very different sizes, but individually you can easily grasp how much they roughly are. Pouring the teaspoon into the swimming pool, however, will leave you still with roughly a swimming pool full of water.

   (If the people learning this have trouble with exponential notation, one can also use the values 1 and 100000000000000000000 or so.)

2. Then there is the problem of binary vs. decimal representation. A number like 0.1 can't be represented exactly with a limited amount of binary digits. Some languages mask this, though:

   PS> "{0:N50}" -f 0.1
   0.10000000000000000000000000000000000000000000000000
   

   But you can “amplify” the representation error by repeatedly adding the numbers together:

   PS> $sum = 0; for ($i = 0; $i -lt 100; $i++) { $sum += 0.1 }; $sum
   9,99999999999998
   

   I can't think of a nice analogy to properly explain this, though. It's basically the same problem why you can represent ¹/₃ only approximately in decimal because to get the exact value you need to repeat the 3 indefinitely at the end of the decimal fraction.

   Similarly, binary fractions are good for representing halves, quarters, eighths, etc. but things like a tenth will yield an infinitely repeating stream of binary digits.

3. Then there is another problem, though most people don't stumble into that, unless they're doing huge amounts of numerical stuff. But then, those already know about the problem. Since many floating-point numbers are merely approximations of the exact value this means that for a given approximation f of a real number r there can be infinitely many more real numbers r₁, r₂, ... which map to exactly the same approximation. Those numbers lie in a certain interval. Let's say that r_min is the minimum possible value of r that results in f and r_max the maximum possible value of r for which this holds, then you got an interval [r_min, r_max] where any number in that interval can be your actual number r.

   Now, if you perform calculations on that number—adding, subtracting, multiplying, etc.—you lose precision. Every number is just an approximation, therefore you're actually performing calculations with intervals. The result is an interval too and the approximation error only ever gets larger, thereby widening the interval. You may get back a single number from that calculation. But that's merely one number from the interval of possible results, taking into account precision of your original operands and the precision loss due to the calculation.

   That sort of thing is called Interval arithmetic and at least for me it was part of our math course at the university.

In python 2 only (not python 3):

assert not isinstance(lst, basestring)

Is actually what you want, otherwise you'll miss out on a lot of things which act like lists, but aren't subclasses of list or tuple.

Try this in your forth column

=COUNTIF(B:B; ">" & B2) + 1

Replace B2 with B3 for next row and so on.

What this does is it counts how many records have more points then current one and then this adds current record position (+1 part).

I am not sure I got you but this might be what you are looking for:

SELECT i.invoiceid, sum(case when i.amount is not null then i.amount else 0 end), sum(case when i.amount is not null then i.amount else 0 end) - sum(case when p.amount is not null then p.amount else 0 end) AS amountdue
FROM invoices i
LEFT JOIN invoicepayments ip ON i.invoiceid = ip.invoiceid
LEFT JOIN payments p ON ip.paymentid = p.paymentid
LEFT JOIN customers c ON p.customerid = c.customerid
WHERE c.customernumber = '100'
GROUP BY i.invoiceid

This would get you the amounts sums in case there are multiple payment rows for each invoice

You can show changes that have been staged with the --cached flag:

$ git diff --cached

In more recent versions of git, you can also use the --staged flag (--staged is a synonym for --cached):

$ git diff --staged

Instead of reinventing the wheel, how about using Apache commons-io:

import org.apache.commons.io.FilenameUtils;

public class FilenameUtilTest {

    public static void main(String[] args) throws Exception {
        URL url = new URL("http://www.example.com/some/path/to/a/file.xml?foo=bar#test");

        System.out.println(FilenameUtils.getBaseName(url.getPath())); // -> file
        System.out.println(FilenameUtils.getExtension(url.getPath())); // -> xml
        System.out.println(FilenameUtils.getName(url.getPath())); // -> file.xml
    }

}

I know this is a somewhat old thread, but I had this problem too with a c#/WPF app I was creating. The app worked fine on the development machine, but would not start on the test machine. The Application Log in the Event Viewer gave a somewhat nebulous .NET Runtime error of System.IO.DirectoryNotFoundException.

I tried using some debugging software but the app would not stay running long enough to attach the debugger to the process. After banging my head against my desk for a day and looking at many web pages like this one, what I wound up doing to troubleshoot this was to install VS2019 on my test machine. I then dragged the .exe file from its folder (it was deep in the Users[user]\AppData\Apps\2.0... folder) to the open VS2019 instance and went to start it from there. Immediately, it came up with a dialog box giving the exception and the cause.

In my case, when I added an icon to one of the forms, the complete path to the icon was placed into the XAML instead of just the icon name. I had copied the icon file into the project folder, but since the project folder does not exist on the test machine, this was the root cause of the error. I then removed the path from the XAML, leaving just the icon name one, rebuilt the solution and re-published it, and it ran just fine on the test machine now. Of course there are many causes besides what gave me the error, but this method of troubleshooting should hopefully identify the root cause of the error, since the Windows Event Viewer gives a somewhat vague answer.

To summarize, use Visual Studio on the test machine as a debugger of sorts. But, to get it to work right, I had to drag the .exe file into the IDE and Start (run) it from there. I believe this will also work with VS2017 as well as VS2019. Hopefully this helps someone who is still having this issue.

If we have parameter like below in our POM XML

<version>${project.version}.${svn.version}</version>
  <packaging>war</packaging>

I run maven command line as follows :

mvn clean install package -Dproject.version=10 -Dsvn.version=1

This strongly implies that your data IS NOT NORMALISED to begin with.

Something like this should work (NB you've not mentioned of your using any other languages - so its written as a MySQL stored procedure)

 create procedure replace_all(find varchar(255), 
        replce varchar(255), 
        indb varcv=char(255))
 DECLARE loopdone INTEGER DEFAULT 0;
 DECLARE currtable varchar(100);
 DECLARE alltables CURSOR FOR SELECT t.tablename, c.column_name 
    FROM information_schema.tables t,
    information_schema.columns c
    WHERE t.table_schema=indb
    AND c.table_schema=indb
    AND t.table_name=c.table_name;

 DECLARE CONTINUE HANDLER FOR NOT FOUND
     SET loopdone = 1;

 OPEN alltables;

 tableloop: LOOP
    FETCH alltables INTO currtable, currcol; 
    IF (loopdone>0) THEN LEAVE LOOP;
    END IF;
         SET stmt=CONCAT('UPDATE ', 
                  indb, '.', currtable, ' SET ',
                  currcol, ' = word_sub(\'', find, 
                  '\','\'', replce, '\') WHERE ',
                  currcol, ' LIKE \'%', find, '%\'');
         PREPARE s1 FROM stmt;
         EXECUTE s1;
         DEALLOCATE PREPARE s1;
     END LOOP;
 END //

I'll leave it to you to work out how to declare the word_sub function.

You need to use a pointer or a reference as the proper type is not known at this time the compiler can not instantiate it.

Instead try:

void action(const typename Subclass::mytype &var) {
            (static_cast<Subclass*>(this))->do_action();
    }

To add to answer given by Anil, In symfony3, you can use $this->getUser() to determine if the user is logged in, a simple condition like if(!$this->getUser()) {} will do.

If you look at the source code which is available in base controller, it does the exact same thing defined by Anil.

Some interesting excerpts from the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.
...
When an interactive shell that is not a login shell is started, bash reads and executes commands from /etc/bash.bashrc and ~/.bashrc, if these files exist. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of /etc/bash.bashrc and ~/.bashrc.

So have a look at /etc/profile or /etc/bash.bashrc, these files are the right places for global settings. Put something like this in them to set up an environement variable:

export MY_VAR=xxx

You could replace the original jQuery addClass and removeClass functions with your own that would call the original functions and then trigger a custom event. (Using a self-invoking anonymous function to contain the original function reference)

(function( func ) {
    $.fn.addClass = function() { // replace the existing function on $.fn
        func.apply( this, arguments ); // invoke the original function
        this.trigger('classChanged'); // trigger the custom event
        return this; // retain jQuery chainability
    }
})($.fn.addClass); // pass the original function as an argument

(function( func ) {
    $.fn.removeClass = function() {
        func.apply( this, arguments );
        this.trigger('classChanged');
        return this;
    }
})($.fn.removeClass);

Then the rest of your code would be as simple as you'd expect.

$(selector).on('classChanged', function(){ /*...*/ });

Update:

This approach does make the assumption that the classes will only be changed via the jQuery addClass and removeClass methods. If classes are modified in other ways (such as direct manipulation of the class attribute through the DOM element) use of something like MutationObservers as explained in the accepted answer here would be necessary.

Also as a couple improvements to these methods:

• Trigger an event for each class being added (classAdded) or removed (classRemoved) with the specific class passed as an argument to the callback function and only triggered if the particular class was actually added (not present previously) or removed (was present previously)

• Only trigger classChanged if any classes are actually changed

  (function( func ) {
      $.fn.addClass = function(n) { // replace the existing function on $.fn
          this.each(function(i) { // for each element in the collection
              var $this = $(this); // 'this' is DOM element in this context
              var prevClasses = this.getAttribute('class'); // note its original classes
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString(); // retain function-type argument support
              $.each(classNames.split(/\s+/), function(index, className) { // allow for multiple classes being added
                  if( !$this.hasClass(className) ) { // only when the class is not already present
                      func.call( $this, className ); // invoke the original function to add the class
                      $this.trigger('classAdded', className); // trigger a classAdded event
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged'); // trigger the classChanged event
          });
          return this; // retain jQuery chainability
      }
  })($.fn.addClass); // pass the original function as an argument
  
  (function( func ) {
      $.fn.removeClass = function(n) {
          this.each(function(i) {
              var $this = $(this);
              var prevClasses = this.getAttribute('class');
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString();
              $.each(classNames.split(/\s+/), function(index, className) {
                  if( $this.hasClass(className) ) {
                      func.call( $this, className );
                      $this.trigger('classRemoved', className);
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged');
          });
          return this;
      }
  })($.fn.removeClass);
  

With these replacement functions you can then handle any class changed via classChanged or specific classes being added or removed by checking the argument to the callback function:

$(document).on('classAdded', '#myElement', function(event, className) {
    if(className == "something") { /* do something */ }
});

%d seems to be the norm for printing integers, I never figured out why, they behave identically.

Well, this will do it, but it's about as fast as it looks (roughly O(n*m), where n is the number of lines to display and m is the total number of lines in the file):

for /l %l in (1,1,10) do @for /f "tokens=1,2* delims=:" %a in ('findstr /n /r "^" filename ^| findstr /r "^%l:"') do @echo %b

Where "10" is the number of lines you want to print, and "filename" is the name of the file.

This is supported in WebKit via webkitEnterFullscreen.

BufferedWriter login = new BufferedWriter(new FileWriter("login.txt"));

is an example if you want to create a file in one line.

By default it will be hidden in your home directory. Type ls -a ~ to view that.

Maybe I read the problem wrong, but I believe you already have inserted the course 11 records and simply need to update those that meet the criteria you listed with course 6's data.

If this is the case, you'll want to use an UPDATE...FROM statement:

UPDATE MyTable
SET
    complete = 1,
    complete_date = newdata.complete_date,
    post_score = newdata.post_score
FROM
    (
    SELECT
        userID,
        complete_date,
        post_score
    FROM MyTable
    WHERE
        courseID = 6
        AND complete = 1
        AND complete_date > '8/1/2008'
    ) newdata
WHERE
    CourseID = 11
    AND userID = newdata.userID

It is simple: if recv() returns 0 bytes; you will not receive any more data on this connection. Ever. You still might be able to send.

It means that your non-blocking socket have to raise an exception (it might be system-dependent) if no data is available but the connection is still alive (the other end may send).

To force git stash pop run this command

git stash show -p | git apply && git stash drop

BLOB :

BLOB (Binary Large Object) is a large object data type in the database system. BLOB could store a large chunk of data, document types and even media files like audio or video files. BLOB fields allocate space only whenever the content in the field is utilized. BLOB allocates spaces in Giga Bytes.

USAGE OF BLOB :

You can write a binary large object (BLOB) to a database as either binary or character data, depending on the type of field at your data source. To write a BLOB value to your database, issue the appropriate INSERT or UPDATE statement and pass the BLOB value as an input parameter. If your BLOB is stored as text, such as a SQL Server text field, you can pass the BLOB as a string parameter. If the BLOB is stored in binary format, such as a SQL Server image field, you can pass an array of type byte as a binary parameter.

A useful link : Storing documents as BLOB in Database - Any disadvantages ?

You can do it in O(n) time using min and index instead of using sort or heapq.

First create new list of everything except the min value of the original list:

new_list = lst[:lst.index(min(lst))] + lst[lst.index(min(lst))+1:]

Then take the min value of the new list:

second_smallest = min(new_list)

Now all together in a single lambda:

map(lambda x: min(x[:x.index(min(x))] + x[x.index(min(x))+1:]), lst)

Yes it is really ugly, but it should be algorithmically cheap. Also since some folks in this thread want to see list comprehensions:

[min(x[:x.index(min(x))] + x[x.index(min(x))+1:]) for x in lst]

To get the root view defined in your xml file, without action bar, you can use this:

View root = ((ViewGroup) findViewById(android.R.id.content)).getChildAt(0);

So, to change color to white:

root.setBackgroundResource(Color.WHITE);

In addition to the tools and methodes provided in the other anwers, static code analysis tools can be used to detect memory leaks (and other issues as well). A free an robust tool is Cppcheck. But there are a lot of other tools available. Wikipedia has a list of static code analysis tools.

Yes. Empty or incomplete headers or response body typically caused by broken connections or server side crash can cause 502 errors if accessed via a gateway or proxy.

I'm pretty sure you can't simply add on delete cascade to an existing foreign key constraint. You have to drop the constraint first, then add the correct version. In standard SQL, I believe the easiest way to do this is to

• start a transaction,
• drop the foreign key,
• add a foreign key with on delete cascade, and finally
• commit the transaction

Repeat for each foreign key you want to change.

But PostgreSQL has a non-standard extension that lets you use multiple constraint clauses in a single SQL statement. For example

alter table public.scores
drop constraint scores_gid_fkey,
add constraint scores_gid_fkey
   foreign key (gid)
   references games(gid)
   on delete cascade;

If you don't know the name of the foreign key constraint you want to drop, you can either look it up in pgAdminIII (just click the table name and look at the DDL, or expand the hierarchy until you see "Constraints"), or you can query the information schema.

select *
from information_schema.key_column_usage
where position_in_unique_constraint is not null

You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.

Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).

EDIT:

Here is some code:

For the UDF:

    Public Function UDF_Date(ByVal data) As Date

        UDF_Date = Now()

    End Function

As Formula in D2:

=UDF_Date(C2)

You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.

And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.

Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.

Addendum:

Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:

• The usage of the UDF is the same as described above.

• The UDF works only for single cell input ranges.

• The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.

• If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.

• The code might brake for cell-values for which conversion to string is non-deterministic.

• The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.

  Public Function UDF_Date(ByVal inData As Range) As Date

      bDate = True
      bValue = True

      End If
  
  On Error GoTo 0
  
      If Not bValue Then
          bChanged = True
          Set pValue = dProps.Add(sName, False, msoPropertyTypeString, sVal)
      Else
          bChanged = pValue.Value <> sVal
          If bChanged Then
              pValue.Value = sVal
          End If
      End If
  
  On Error Resume Next
  
      Set pDate = dProps.Item(sNameDate)
  
      If Err.Number <> 0 Then
          bDate = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bDate Then
          Set pDate = dProps.Add(sNameDate, False, msoPropertyTypeDate, dDate)
      End If
  
      If bChanged Then
          pDate.Value = dDate
      Else
          dDate = pDate.Value
      End If
  
  
      UDF_Date = dDate
   End Function
  

Make the insertion of the date conditional upon the range.

This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

I like the idea of wrapping this in a class and implementing __getitem__ and __setitem__ such that they implemented a simple query language:

>>> d['new jersey/mercer county/plumbers'] = 3
>>> d['new jersey/mercer county/programmers'] = 81
>>> d['new jersey/mercer county/programmers']
81
>>> d['new jersey/mercer country']
<view which implicitly adds 'new jersey/mercer county' to queries/mutations>

If you wanted to get fancy you could also implement something like:

>>> d['*/*/programmers']
<view which would contain 'programmers' entries>

but mostly I think such a thing would be really fun to implement :D

Try:Right Click your project->Maven->Disable Dependency Management. And re-enable dependency management.

First of all what you have to understand is that str+= will resize your string memory to make space for 1 extra char. This is fine, but if you have, say, a book with 1000 pages that you want to reverse, this will take very long to execute.

The solution that some people might suggest is using StringBuilder. What string builder does when you perform a += is that it allocates much larger chunks of memory to hold the new character so that it does not need to do a reallocation every time you add a char.

If you really want a fast and minimal solution I'd suggest the following:

            char[] chars = new char[str.Length];
            for (int i = str.Length - 1, j = 0; i >= 0; --i, ++j)
            {
                chars[j] = str[i];
            }
            str = new String(chars);

In this solution there is one initial memory allocation when the char[] is initialized and one allocation when the string constructor builds the string from the char array.

On my system I ran a test for you that reverses a string of 2 750 000 characters. Here are the results for 10 executions:

StringBuilder: 190K - 200K ticks

Char Array: 130K - 160K ticks

I also ran a test for normal String += but I abandoned it after 10 minutes with no output.

However, I also noticed that for smaller strings the StringBuilder is faster, so you will have to decide on the implementation based on the input.

Cheers

Try:

msg['Subject'] = "Auto Hella Restart Report " + sys.argv[1]

The + operator is overridden in python to concatenate strings.

I prefer to use this instead of TempData

public class Home1Controller : Controller 
{
    [HttpPost]
    public ActionResult CheckBox(string date)
    {
        return RedirectToAction("ActionName", "Home2", new { Date =date });
    }
}

and another controller Action is

Logical link control and adaptation protocol (L2CAP)

L2CAP is used within the Bluetooth protocol stack. It passes packets to either the Host Controller Interface (HCI) or on a hostless system, directly to the Link Manager/ACL link. L2CAP's functions include:

• Multiplexing data between different higher layer protocols.
• Segmentation and reassembly of packets.
• Providing one-way transmission management of multicast data to a group of other Bluetooth devices.
• Quality of service (QoS) management for higher layer protocols.

L2CAP is used to communicate over the host ACL link. Its connection is established after the ACL link has been set up.

Disclosure: I wrote the code that Trello uses; the code below is the actual source code Trello uses to accomplish the clipboard trick.

We don't actually "access the user's clipboard", instead we help the user out a bit by selecting something useful when they press Ctrl+C.

Sounds like you've figured it out; we take advantage of the fact that when you want to hit Ctrl+C, you have to hit the Ctrl key first. When the Ctrl key is pressed, we pop in a textarea that contains the text we want to end up on the clipboard, and select all the text in it, so the selection is all set when the C key is hit. (Then we hide the textarea when the Ctrl key comes up.)

Specifically, Trello does this:

TrelloClipboard = new class
  constructor: ->
    @value = ""

    $(document).keydown (e) =>
      # Only do this if there's something to be put on the clipboard, and it
      # looks like they're starting a copy shortcut
      if !@value || !(e.ctrlKey || e.metaKey)
        return

      if $(e.target).is("input:visible,textarea:visible")
        return

      # Abort if it looks like they've selected some text (maybe they're trying
      # to copy out a bit of the description or something)
      if window.getSelection?()?.toString()
        return

      if document.selection?.createRange().text
        return

      _.defer =>
        $clipboardContainer = $("#clipboard-container")
        $clipboardContainer.empty().show()
        $("<textarea id='clipboard'></textarea>")
        .val(@value)
        .appendTo($clipboardContainer)
        .focus()
        .select()

    $(document).keyup (e) ->
      if $(e.target).is("#clipboard")
        $("#clipboard-container").empty().hide()

  set: (@value) ->

In the DOM we've got:

<div id="clipboard-container"><textarea id="clipboard"></textarea></div>

CSS for the clipboard stuff:

#clipboard-container {
  position: fixed;
  left: 0px;
  top: 0px;
  width: 0px;
  height: 0px;
  z-index: 100;
  display: none;
  opacity: 0;
}
#clipboard {
  width: 1px;
  height: 1px;
  padding: 0px;
}

... and the CSS makes it so you can't actually see the textarea when it pops in ... but it's "visible" enough to copy from.

When you hover over a card, it calls

TrelloClipboard.set(cardUrl)

... so then the clipboard helper knows what to select when the Ctrl key is pressed.

I really like var_dump()'s verbose output and wasn't satisfied with var_export()'s or print_r()'s output because it didn't give as much information (e.g. data type missing, length missing).

To write secure and predictable code, sometimes it's useful to differentiate between an empty string and a null. Or between a 1 and a true. Or between a null and a false. So I want my data type in the output.

Although helpful, I didn't find a clean and simple solution in the existing responses to convert the colored output of var_dump() to a human-readable output into a string without the html tags and including all the details from var_dump().

Note that if you have a colored var_dump(), it means that you have Xdebug installed which overrides php's default var_dump() to add html colors.

For that reason, I created this slight variation giving exactly what I need:

function dbg_var_dump($var)
    {
        ob_start();
        var_dump($var);
        $result = ob_get_clean();
        return strip_tags(strtr($result, ['=>' => '=>']));
    }

Returns the below nice string:

array (size=6)
  'functioncall' => string 'add-time-property' (length=17)
  'listingid' => string '57' (length=2)
  'weekday' => string '0' (length=1)
  'starttime' => string '00:00' (length=5)
  'endtime' => string '00:00' (length=5)
  'price' => string '' (length=0)

Hope it helps someone.

This works for Oracle and SQL Server (you might be able to get it to work on another RDBMS):

select sum(case when a is null then 1 else 0 end) count_nulls
     , count(a) count_not_nulls 
  from us;

Or:

select count(*) - count(a), count(a) from us;

I went through this when trying to get a clientcert and private key out of a keystore.

The link above posted by welsh was great, but there was an extra step on my redhat distribution. If curl is built with NSS ( run curl --version to see if you see NSS listed) then you need to import the keys into an NSS keystore. I went through a bunch of convoluted steps, so this may not be the cleanest way, but it got things working

So export the keys into .p12

keytool -importkeystore -srckeystore $jksfile -destkeystore $p12file \
        -srcstoretype JKS -deststoretype PKCS12 \
        -srcstorepass $jkspassword -deststorepass $p12password  
        -srcalias $myalias -destalias $myalias \
        -srckeypass $keypass -destkeypass $keypass -noprompt

And generate the pem file that holds only the key

 echo making ${fileroot}.key.pem
 openssl pkcs12 -in $p12 -out ${fileroot}.key.pem  \
         -passin pass:$p12password  \
         -passout pass:$p12password  -nocerts

• Make an empty keystore:

mkdir ~/nss
chmod 700 ~/nss
certutil -N -d ~/nss

• Import the keys into the keystore

pks12util -i <mykeys>.p12 -d ~/nss -W <password for cert >

Now curl should work.

curl --insecure --cert <client cert alias>:<password for cert> \
     --key ${fileroot}.key.pem  <URL>

As I mentioned, there may be other ways to do this, but at least this was repeatable for me. If curl is compiled with NSS support, I was not able to get it to pull the client cert from a file.

I did it the following way:

1. Generate a unique hash, and then store it in redis and your JWT. This can be called a session
   • We'll also store the number of requests the particular JWT has made - Each time a jwt is sent to the server, we increment the requests integer. (this is optional)

So when a user logs in, a unique hash is created, stored in redis and injected into your JWT.

When a user tries to visit a protected endpoint, you'll grab the unique session hash from your JWT, query redis and see if it's a match!

We can extend from this and make our JWT even more secure, here's how:

Every X requests a particular JWT has made, we generate a new unique session, store it in our JWT, and then blacklist the previous one.

This means that the JWT is constantly changing and stops stale JWT's being hacked, stolen, or something else.

Check out the contents of your array with

echo '<pre>' . print_r( $arr, TRUE ) . '</pre>';

I've written this, but have to check the existing methods mentioned to see if they are better.

module PrettyDate
  def to_pretty
    a = (Time.now-self).to_i

      when 2..59 then a.to_s+' seconds ago' 
      when 60..119 then 'a minute ago' #120 = 2 minutes
      when 120..3540 then (a/60).to_i.to_s+' minutes ago'
      when 3541..7100 then 'an hour ago' # 3600 = 1 hour
      when 7101..82800 then ((a+99)/3600).to_i.to_s+' hours ago' 
      when 82801..172000 then 'a day ago' # 86400 = 1 day
      when 172001..518400 then ((a+800)/(60*60*24)).to_i.to_s+' days ago'

You can use my solution, this is the most convenient way. It’s also free.

Create state machine in three steps :

1. Create scheme in node editor and load it in your project using library

StateMachine stateMachine = new StateMachine("scheme.xml");

2. Describe your app logic on events?

stateMachine.GetState("State1").OnExit(Action1);
stateMachine.GetState("State2").OnEntry(Action2);
stateMachine.GetTransition("Transition1").OnInvoke(Action3);
stateMachine.OnChangeState(Action4);

3. Run the state machine

stateMachine.Start();

Links:

Node editor: https://github.com/SimpleStateMachine/SimpleStateMachineNodeEditor

Library: https://github.com/SimpleStateMachine/SimpleStateMachineLibrary

You can do this:

satView.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

       @Override
       public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {

       }
   }
);     

I created a simple scheduler that is easy to use and you do not need to use external library. TaskScheduler is a singleton that keeps references on the timers so timers will not be garbage collected, it can schedule multiple tasks. You can set the first run (hour and minute), if at the time of scheduling this time is over scheduling start on the next day this at that time. But it is easy to customize the code.

Scheduling a new task is so simple. Example: At 11:52 the first task is for every 15 secunds, the second example is for every 5 secunds. For daily execution set 24 to the 3 parameter.

TaskScheduler.Instance.ScheduleTask(11, 52, 0.00417, 
    () => 
    {
        Debug.WriteLine("task1: " + DateTime.Now);
        //here write the code that you want to schedule
    });

TaskScheduler.Instance.ScheduleTask(11, 52, 0.00139,
    () =>
    {
        Debug.WriteLine("task2: " + DateTime.Now);
        //here write the code that you want to schedule
    });

My debug window:

task2: 07.06.2017 11:52:00
task1: 07.06.2017 11:52:00
task2: 07.06.2017 11:52:05
task2: 07.06.2017 11:52:10
task1: 07.06.2017 11:52:15
task2: 07.06.2017 11:52:15
task2: 07.06.2017 11:52:20
task2: 07.06.2017 11:52:25
...

Just add this class to your project:

public class TaskScheduler
{
    private static TaskScheduler _instance;
    private List<Timer> timers = new List<Timer>();

    private TaskScheduler() { }

    public static TaskScheduler Instance => _instance ?? (_instance = new TaskScheduler());

    public void ScheduleTask(int hour, int min, double intervalInHour, Action task)
    {
        DateTime now = DateTime.Now;
        DateTime firstRun = new DateTime(now.Year, now.Month, now.Day, hour, min, 0, 0);
        if (now > firstRun)
        {
            firstRun = firstRun.AddDays(1);
        }

        TimeSpan timeToGo = firstRun - now;
        if (timeToGo <= TimeSpan.Zero)
        {
            timeToGo = TimeSpan.Zero;
        }

        var timer = new Timer(x =>
        {
            task.Invoke();
        }, null, timeToGo, TimeSpan.FromHours(intervalInHour));

        timers.Add(timer);
    }
}

When you want a relative path from your home directory (on any UNIX) you use this strange syntax:

ssh://[user@]host.xz[:port]/~[user]/path/to/repo

For Example, if the repo is in /home/jack/projects/jillweb on the server jill.com and you are logging in as jack with sshd listening on port 4242:

ssh://[email protected]:4242/~/projects/jillweb

And when logging in as jill (presuming you have file permissions):

ssh://[email protected]:4242/~jack/projects/jillweb

For a Windows console app, you want to use SetConsoleCtrlHandler to handle CTRL+C and CTRL+BREAK.

See here for an example.

It is very simple two way data binding in vanilla javascript....

<input type="text" id="inp" onkeyup="document.getElementById('name').innerHTML=document.getElementById('inp').value;">

<div id="name">

</div>

The chosen answer does work however I wanted to make a comment that having 'ngModel' on the html tag causes the checkbox checked to not be set to true.

This occurs when you are trying to do bind using the checked property. i.e.

<mat-checkbox [checked]='var' ngModel name='some_name'></mat-checkbox>

And then inside your app.component.ts file

var = true;

will not work.

TLDR: Remove ngModel if you are setting the checked through the [checked] property

    <mat-checkbox [checked]='var' name='some_name'></mat-checkbox>

Tests whether windowsize is greater than 500 and lesser than 600 meaning that neither values 500 or 600 itself will result in the condition becoming true.

if (windowsize > 500 && windowsize < 600) {
  // ...
}

My way:

private static int hexToDec(String hex) {
    return Integer.parseInt(hex, 16);
}

-H "text/xml" isn't a valid header. You need to provide the full header:

-H "Content-Type: text/xml" 

I have a Samsung Galaxy and I had the same issue as you. Here's how to fix it:

In device manager on your Windows PC, even though it might say the USB drivers are installed correctly, there may exist corruption.

I went into device manager and uninstalled SAMSUNG Android USB Composite Device and made sure to check the box 'delete driver software'. Now the device will have an exclamation mark etc. I right clicked and installed the driver again (refresh copy). This finally made adb acknowledge my phone as an emulator.

As others noted, for Nexus 4, you can also try this fix.

Try this...

<div class="row">
    <div class="col-xs-3">
        Menu
    </div>
    <div class="col-xs-9">
        <div class="row">
          <div class="col-sm-4 col-sm-push-8">
          Right content
          </div>
          <div class="col-sm-8 col-sm-pull-4">
          Content
          </div>
       </div>
    </div>
</div>

Here is ultimate unique id generator for you. made by me.

<?php
$d=date ("d");
$m=date ("m");
$y=date ("Y");
$t=time();
$dmt=$d+$m+$y+$t;    
$ran= rand(0,10000000);
$dmtran= $dmt+$ran;
$un=  uniqid();
$dmtun = $dmt.$un;
$mdun = md5($dmtran.$un);
$sort=substr($mdun, 16); // if you want sort length code.

echo $mdun;
?>

you can echo any 'var' for your id as you like. but $mdun is better, you can replace md5 to sha1 for better code but that will be very long which may you dont need.

Thank you.

Now apparently \r, \b, \t, \f, etc aren't the only problematic chars that can give you this error.

Note that some browsers may have additional requirements for the input of JSON.parse.

Run this test code on your browser:

var arr = [];
for(var x=0; x < 0xffff; ++x){
    try{
        JSON.parse(String.fromCharCode(0x22, x, 0x22));
    }catch(e){
        arr.push(x);
    }
}
console.log(arr);

Testing on Chrome, I see that it doesn't allow JSON.parse(String.fromCharCode(0x22, x, 0x22)); where x is 34, 92, or from 0 to 31.

Chars 34 and 92 are the " and \ characters respectively, and they are usually expected and properly escaped. It's chars 0 to 31 that would give you problems.

To help with debugging, before you do JSON.parse(input), first verify that the input doesn't contain problematic characters:

function VerifyInput(input){
    for(var x=0; x<input.length; ++x){
        let c = input.charCodeAt(x);
        if(c >= 0 && c <= 31){
            throw 'problematic character found at position ' + x;
        }
    }
}

In C# 5.0, this problem is fixed and you can close over loop variables and get the results you expect.

The language specification says:

8.8.4 The foreach statement

(...)

A foreach statement of the form

foreach (V v in x) embedded-statement

is then expanded to:

{
  E e = ((C)(x)).GetEnumerator();
  try {
      while (e.MoveNext()) {
          V v = (V)(T)e.Current;
          embedded-statement
      }
  }
  finally {
      … // Dispose e
  }
}

(...)

The placement of v inside the while loop is important for how it is captured by any anonymous function occurring in the embedded-statement. For example:

int[] values = { 7, 9, 13 };
Action f = null;
foreach (var value in values)
{
    if (f == null) f = () => Console.WriteLine("First value: " + value);
}
f();

If v was declared outside of the while loop, it would be shared among all iterations, and its value after the for loop would be the final value, 13, which is what the invocation of f would print. Instead, because each iteration has its own variable v, the one captured by f in the first iteration will continue to hold the value 7, which is what will be printed. (Note: earlier versions of C# declared v outside of the while loop.)

If you mean VB 6, that would be Private Sub Class_Initialize().

http://msdn.microsoft.com/en-us/library/55yzhfb2(VS.80).aspx

If you mean VB.NET it is Public Sub New() or Shared Sub New().

In Reactive Form, there are 2 primary solutions to update value(s) of form field(s).

setValue:

• Initialize Model Structure in Constructor:

  this.newForm = this.formBuilder.group({  
     firstName: ['', [Validators.required, Validators.minLength(3), Validators.maxLength(8)]],
     lastName: ['', [Validators.required, Validators.minLength(3), Validators.maxLength(8)]]
  });
  

• If you want to update all fields of form:

  this.newForm.setValue({
     firstName: 'abc',
     lastName: 'def'
  });
  

• If you want to update specific field of form:

  this.newForm.controls.firstName.setValue('abc');
  

Note: It’s mandatory to provide complete model structure for all form field controls within the FormGroup. If you miss any property or subset collections, then it will throw an exception.

patchValue:

• If you want to update some/ specific fields of form:

  this.newForm.patchValue({
     firstName: 'abc'
  });
  

Note: It’s not mandatory to provide model structure for all/ any form field controls within the FormGroup. If you miss any property or subset collections, then it will not throw any exception.

Abstract methods means there is no default implementation for it and an implementing class will provide the details.

Essentially, you would have

abstract class AbstractObject {
   public abstract void method();
}

class ImplementingObject extends AbstractObject {
  public void method() {
    doSomething();
  }
}

So, it's exactly as the error states: your abstract method can not have a body.

There's a full tutorial on Oracle's site at: http://download.oracle.com/javase/tutorial/java/IandI/abstract.html

The reason you would do something like this is if multiple objects can share some behavior, but not all behavior.

A very simple example would be shapes:

You can have a generic graphic object, which knows how to reposition itself, but the implementing classes will actually draw themselves.

(This is taken from the site I linked above)

abstract class GraphicObject {
    int x, y;
    ...
    void moveTo(int newX, int newY) {
        ...
    }
    abstract void draw();
    abstract void resize();
}

class Circle extends GraphicObject {
    void draw() {
        ...
    }
    void resize() {
        ...
    }
}
class Rectangle extends GraphicObject {
    void draw() {
        ...
    }
    void resize() {
        ...
    }
}

i have just tried it and this works perfectly

USE YourDatabseName
GO
SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%YourColumnName%'
ORDER BY schema_name, table_name;

Only change YourDatbaseName to your database and YourcolumnName to your column name that you are looking for the rest keep it as it is.

Hope this has helped

Create Table as select (CTAS) is possible in Hive.

You can try out below command:

CREATE TABLE new_test 
    row format delimited 
    fields terminated by '|' 
    STORED AS RCFile 
AS select * from source where col=1

1. Target cannot be partitioned table.
2. Target cannot be external table.
3. It copies the structure as well as the data

Create table like is also possible in Hive.

1. It just copies the source table definition.

Assigning a class name and applying a CSS style are two different things.

If you mean <img class="someclass">, and

.someclass {
  [cssrule]
}

, then there is no real performance difference between applying the css to the class, or to .column img

Suggested changes:

• Do not invoke the Command object's Execute method;
• Set the Recordset object's Source property to be your Command object;
• Invoke the Recordset object's Open method with no parameters;
• Remove the parentheses from around the Recordset object in the call to CopyFromRecordset;
• Actually declare your variables :)

    'Declare variables'
        Dim objMyConn As ADODB.Connection
        Dim objMyCmd As ADODB.Command
        Dim objMyRecordset As ADODB.Recordset

        Set objMyConn = New ADODB.Connection
        Set objMyCmd = New ADODB.Command
        Set objMyRecordset = New ADODB.Recordset

    'Open Connection'
        objMyConn.ConnectionString = "Provider=SQLOLEDB;Data Source=localhost;User ID=abc;Password=abc;"    
        objMyConn.Open

    'Set and Excecute SQL Command'
        Set objMyCmd.ActiveConnection = objMyConn
        objMyCmd.CommandText = "select * from mytable"
        objMyCmd.CommandType = adCmdText

    'Open Recordset'
        Set objMyRecordset.Source = objMyCmd
        objMyRecordset.Open

    'Copy Data to Excel'
        ActiveSheet.Range("A1").CopyFromRecordset objMyRecordset

End Sub

I found the solution here in this link.

You just have to place below code in your Android application class. And that is enough. Don't need to do any changes in your Retrofit settings. It saved my day.

public class MyApplication extends Application {
@Override
public void onCreate() {
    super.onCreate();
    try {
      // Google Play will install latest OpenSSL 
      ProviderInstaller.installIfNeeded(getApplicationContext());
      SSLContext sslContext;
      sslContext = SSLContext.getInstance("TLSv1.2");
      sslContext.init(null, null, null);
      sslContext.createSSLEngine();
    } catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException
        | NoSuchAlgorithmException | KeyManagementException e) {
        e.printStackTrace();
        }
    }
}

Hope this will be of help. Thank you.

URLs are defined in RFC 3986, though other RFCs are relevant as well but RFC 1738 is obsolete.

They may not have spaces in them, along with many other characters. Since those forbidden characters often need to be represented somehow, there is a scheme for encoding them into a URL by translating them to their ASCII hexadecimal equivalent with a "%" prefix.

Most programming languages/platforms provide functions for encoding and decoding URLs, though they may not properly adhere to the RFC standards. For example, I know that PHP does not.

You are getting an HTTP 400 (Bad Request) error because there is a space in your URL. If you fix it (before the zoom parameter), you will get an HTTP 400 error (Unauthorized). Maybe you need some HTTP header to identify your download as a recognised browser (use the "User-Agent" header) or additional authentication parameter.

For the User-Agent example, then use the ImageIO.read(InputStream) using the connection inputstream:

URLConnection connection = url.openConnection();
connection.setRequestProperty("User-Agent", "xxxxxx");

Use whatever needed for xxxxxx

You've mixed tabs and spaces. This can lead to some confusing errors.

I'd suggest using only tabs or only spaces for indentation.

Using only spaces is generally the easier choice. Most editors have an option for automatically converting tabs to spaces. If your editor has this option, turn it on.

As an aside, your code is more verbose than it needs to be. Instead of this:

if str_p == str_q:
    result = True
else:
    result = False
return result

Just do this:

return str_p == str_q

You also appear to have a bug on this line:

str_q = p[b+1:]

I'll leave you to figure out what the error is.

The following worked for me:

Put your curl statement in a script named abc.sh

Now run:

sh abc.sh 1>stdout_output 2>stderr_output

You will get your curl's results in stdout_output and the progress info in stderr_output.

I use port 465 all the time.

The answer by danorton is outdated. As he and Wikipedia say, port 465 was initially planned for the SMTPS encryption and quickly deprecated 15 years ago. But a lot of ISPs are still using port 465, especially to be in compliance with the current recommendations of RFC 8314, which encourages the use of implicit TLS instead of the use of the STARTTLS command with port 587. (See section 3.3). Using port 465 is the only way to begin an implicitly secure session with an SMTP server that is acting as a mail submission agent (MSA).

Basically, what RFC 8314 recommends is that cleartext email exchanges be abandoned and that all three common IETF mail protocols be used only in implicit TLS sessions for consistency when possible. The recommended secure ports, then, are 465, 993, and 995 for SMTPS, IMAP4S, and POP3S, respectively.

Although RFC 8314 certainly allows the continued use of explicit TLS with port 587 and the STARTTLS command, doing so opens up the mail user agent (MUA, the mail client) to a downgrade attack where a man-in-the-middle intercepts the STARTTLS request to upgrade to TLS security but denies it, thus forcing the session to remain in cleartext.

"final" guarantees that a variable must be initialized before end of object initializer code. Likewise "static final" guarantees that a variable will be initialized by the end of class initialization code. Omitting the "static" from your initialization code turns it into object initialization code; thus your variable no longer satisfies its guarantees.

Thats because its tied to the web view not the button. I had the same problem after implementing. The button had no affect but the page in the web view did.

You can do forward typedef. But to do

typedef A B;

you must first forward declare A:

class A;

typedef A B;

Use p{width} column specifier: e.g. \begin{tabular}{ l p{10cm} } will put column's content into 10cm-wide parbox, and the text will be properly broken to several lines, like in normal paragraph.

You can also use tabular* environment to specify width for the entire table.

Try with below logic

driver.get("http://www.labmultis.info/jpecka.portal-exdrazby/index.php?c1=2&a=s&aa=&ta=1");

List<WebElement> allElements=driver.findElements(By.cssSelector(".list.list-categories li"));

for(WebElement ele :allElements) {
    System.out.println("Name + Number===>"+ele.getText());
    String s=ele.getText();
    s=s.substring(s.indexOf("(")+1, s.indexOf(")"));
    System.out.println("Number==>"+s);
}

====Output======
Name + Number===>Vše (950)
Number==>950
Name + Number===>Byty (181)
Number==>181
Name + Number===>Domy (512)
Number==>512
Name + Number===>Pozemky (172)
Number==>172
Name + Number===>Chaty (28)
Number==>28
Name + Number===>Zemedelské objekty (5)
Number==>5
Name + Number===>Komercní objekty (30)
Number==>30
Name + Number===>Ostatní (22)

/* this will change the HTML content with the new HTML that you want to update in your modal without too many resets... */

var = ""; //HTML to be changed 

$(".classbuttonClicked").click(function() {

With DateTime API:

$dateTime = new DateTime('2008-09-22'); 
echo $dateTime->format('U'); 

// or 

$date = new DateTime('2008-09-22');
echo $date->getTimestamp();

The same with the procedural API:

$date = date_create('2008-09-22');
echo date_format($date, 'U');

// or

$date = date_create('2008-09-22');
echo date_timestamp_get($date);

If the above fails because you are using a unsupported format, you can use

$date = DateTime::createFromFormat('!d-m-Y', '22-09-2008');
echo $dateTime->format('U'); 

// or

$date = date_parse_from_format('!d-m-Y', '22-09-2008');
echo date_format($date, 'U');

Note that if you do not set the !, the time portion will be set to current time, which is different from the first four which will use midnight when you omit the time.

Yet another alternative is to use the IntlDateFormatter API:

$formatter = new IntlDateFormatter(
    'en_US',
    IntlDateFormatter::FULL,
    IntlDateFormatter::FULL,
    'GMT',
    IntlDateFormatter::GREGORIAN,
    'dd-MM-yyyy'
);
echo $formatter->parse('22-09-2008');

Unless you are working with localized date strings, the easier choice is likely DateTime.

on Mac:

• First goto ~/Library/Preferences/SmartGit/19.1
• Second goto preferences.yml file and just comment listx line
• Third open smart git

why you need a for-loop for this? the solution is very obvious:

answers.add(answer1);
answers.add(answer2);
answers.add(answer3);

that's it. no for-loop needed.

First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.

For example,

> z <- factor(letters[c(3, 2, 3, 4)])

# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d

# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"

here, z has 4 elements.
The index is 2, 1, 2, 3 in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.

Then, as.numeric converts simply the index part of factor into numeric.
as.character handles the index and levels, and generates character vector expressed by its level.

?as.numeric says that Factors are handled by the default method.

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-checkout Documentation
• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

This page comes first when you search on Google "remove last character jquery"

Although all previous answers are correct, somehow did not helped me to find what I wanted in a quick and easy way.

I feel something is missing. Apologies if i'm duplicating

jQuery

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

or

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

(Additional step from solution above for if you are missing the AutoReconnect or Offline registry value)

For Visual Studio 2015, Version 14

1. Turn off all VS instances
2. HKEY_CURRENT_USER\SOFTWARE\Microsoft\VisualStudio\14.0\TeamFoundation\Instances{YourServerName}\Collections{TheCollectionName} (To get to this directory on Windows, hit the Windows + R key and search for "regedit")
3. Set both the Offline and AutoReconnect values to 0.
4. If you are missing one of those attributes (in my case I was missing AutoReconnect), right click and and create a new DWORD(32-bit) value with the desired missing name, AutoReconnect or Offline.
5. Again, make sure both values are set to zero.
6. Restart your solution

When you convert your string to a date you need to match the date mask to the format in the string. This includes a time element, which you need to remove with truncation:

select 
    p1.PA_VALUE as StartDate,
    p2.PA_VALUE as EndDate
from WP_Work p 
LEFT JOIN PARAMETER p1 on p1.WP_ID=p.WP_ID AND p1.NAME = 'StartDate'
LEFT JOIN PARAMETER p2 on p2.WP_ID=p.WP_ID AND p2.NAME = 'Date_To'
WHERE p.TYPE = 'EventManagement2'
AND trunc(TO_DATE(p1.PA_VALUE, 'DD-MM-YYYY HH24:MI')) >= TO_DATE('25/10/2012', 'DD/MM/YYYY')
AND trunc(TO_DATE(p2.PA_VALUE, 'DD-MM-YYYY HH24:MI')) <= TO_DATE('26/10/2012', 'DD/MM/YYYY')

If you always want to strip leading brackets:

"[12,23,987,43".gsub(/^\[/, "")

If you just want to remove the first character, and you know it won't be in a multibyte character set:

"[12,23,987,43"[1..-1]

or

"[12,23,987,43".slice(1..-1)

finish your current_activity using method finish() onBack method of your current_activity

and then add below lines in onDestroy of the current_activity for Removing Force close

@Override
public void onDestroy()
{
    android.os.Process.killProcess(android.os.Process.myPid());
    super.onDestroy();
}

Partial import from lodash should work in angular 4.1.x using following notation:

let assign = require('lodash/assign');

Or use 'lodash-es' and import in module:

import { assign } from 'lodash-es';

This is sort of an indirect approach, but you could see if a website loads on your web browser of choice from whatever is running on port 80. Or you could telnet to port 80 and see if you get a response that gives you a clue as to what is running on that port and you can go shut it down. Since port 80 is the default port for http traffic chances are there is some sort of http server running there by default, but there's no guarantee.

I am using Mac and none of the answers above helped me. I found out that maven loads its own JAVA_HOME from the path specified in: ~/.mavenrc

I changed the content of the file to be: JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home

For Linux it will look something like:
JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre

You can throw an unchecked exception from the method which you wish to roll back. This will be detected by spring and your transaction will be marked as rollback only.

I'm assuming you're using Spring here. And I assume the annotations you refer to in your tests are the spring test based annotations.

The recommended way to indicate to the Spring Framework's transaction infrastructure that a transaction's work is to be rolled back is to throw an Exception from code that is currently executing in the context of a transaction.

and note that:

please note that the Spring Framework's transaction infrastructure code will, by default, only mark a transaction for rollback in the case of runtime, unchecked exceptions; that is, when the thrown exception is an instance or subclass of RuntimeException.

System.in.read() reads from the standard input.

The standard input can be used to get input from user in a console environment but, as such user interface has no editing facilities, the interactive use of standard input is restricted to courses that teach programming.

Most production use of standard input is in programs designed to work inside Unix command-line pipelines. In such programs the payload that the program is processing is coming from the standard input and the program's result gets written to the standard output. In that case the standard input is never written directly by the user, it is the redirected output of another program or the contents of a file.

A typical pipeline looks like this:

# list files and directories ordered by increasing size
du -s * | sort -n

sort reads its data from the standard input, which is in fact the output of the du command. The sorted data is written to the standard output of sort, which ends up on the console by default, and can be easily redirected to a file or to another command.

As such, the standard input is comparatively rarely used in Java.

    <ng-include src="'views/sidepanel.html'"></ng-include>

OR

    <div ng-include="'views/sidepanel.html'"></div>

OR

    <div ng-include src="'views/sidepanel.html'"></div>

Points To Remember:

--> No spaces in src

--> Remember to use single quotation in double quotation for src

    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    DocumentBuilder db = dbf.newDocumentBuilder();
    Document dom = db.parse("file.xml");
    Element docEle = dom.getDocumentElement();
    NodeList nl = docEle.getChildNodes();
    int length = nl.getLength();
    for (int i = 0; i < length; i++) {
        if (nl.item(i).getNodeType() == Node.ELEMENT_NODE) {
            Element el = (Element) nl.item(i);
            if (el.getNodeName().contains("staff")) {
                String name = el.getElementsByTagName("name").item(0).getTextContent();
                String phone = el.getElementsByTagName("phone").item(0).getTextContent();
                String email = el.getElementsByTagName("email").item(0).getTextContent();
                String area = el.getElementsByTagName("area").item(0).getTextContent();
                String city = el.getElementsByTagName("city").item(0).getTextContent();
            }
        }
    }

Iterate over all children and nl.item(i).getNodeType() == Node.ELEMENT_NODE is used to filter text nodes out. If there is nothing else in XML what remains are staff nodes.

For each node under stuff (name, phone, email, area, city)

 el.getElementsByTagName("name").item(0).getTextContent(); 

el.getElementsByTagName("name") will extract the "name" nodes under stuff, .item(0) will get you the first node and .getTextContent() will get the text content inside.

Edit: Since we have jackson I would do this in a different way. Define a pojo for the object:

public class Staff {
    private String name;
    private String phone;
    private String email;
    private String area;
    private String city;
...getters setters
}

Then using jackson:

    JsonNode root = new XmlMapper().readTree(xml.getBytes());
    ObjectMapper mapper = new ObjectMapper();
    root.forEach(node -> consume(node, mapper));



private void consume(JsonNode node, ObjectMapper mapper) {
    try {
        Staff staff = mapper.treeToValue(node, Staff.class);
        //TODO your job with staff
    } catch (JsonProcessingException e) {
        e.printStackTrace();
    }
}

So if you are using bootstrap4 then this will work.

<style>
   .tooltip-inner {
    white-space: pre-wrap;
   }

</style>

<script> 
    $(function () {
      $('[data-toggle="tooltip"]').tooltip()
    })
</script>

<a data-toggle="tooltip" data-placement="auto" title=" first line &#010; next line" href= ""> Hover me </a>

If you are using in Django project then we can also display dynamic data in tooltips like:

<a class="black-text pb-2 pt-1" data-toggle="tooltip" data-placement="auto"  title="{{ post.location }} &#010; {{ post.updated_on }}" href= "{% url 'blog:get_user_profile' post.author.id %}">{{ post.author }}</a>

The regular expression method should work. However what you can also do is lower case the string from the database, lower case the %variables% you have, and then locate the positions and lengths in the lower cased string from the database. Remember, positions in a string don't change just because its lower cased.

Then using a loop that goes in reverse (its easier, if you do not you will have to keep a running count of where later points move to) remove from your non-lower cased string from the database the %variables% by their position and length and insert the replacement values.

Your CSS is actually setting the rest of the document to not show overflow therefore the document itself isn't scrolling. The easiest fix for this is bind the event to the thing that is scrolling, which in your case is div#page.

So its easy as changing:

$(document).scroll(function() {  // OR  $(window).scroll(function() {
    didScroll = true;
});

to

$('div#page').scroll(function() {
    didScroll = true;
});

Float them both the same way and add the margin of 40px. If you have 2 elements floating opposite ways you will have much less control and the containing element will determine how far apart they are.

#left{
    float: left;
    margin-right: 40px;
}
#right{
   float: left;
}

Add script with query parameters

That was my case. It actually links to question #4485874, but I'm going to explain it here shortly.
When you try to require path/to/script.php?parameter=value, PHP looks for file named script.php?parameter=value, because UNIX allows you to have paths like this.
If you are really need to pass some data to included script, just declare it as $variable=... or $GLOBALS[]=... or other way you like.

Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.

If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like

double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);

(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)

Docotic.Pdf library can be easily used to create PDF files at runtime. The library can also modify existing PDF documents (extract text/images, append pages, fill form fields, etc.)

Samples for common tasks are available on the library site.

I'm posting this since I have always been struggling when renaming a project in XCode.

Renaming the project is good and simple but this doesn't rename the source folder. Here is a step by step of what I have done that worked great in Xcode 4 and 5 thanks to the links below.

REF links:
Rename Project.
Rename Source Folder and other files.

1- Backup your project.

If you are using git, commit any changes, make a copy of the entire project folder and backup in time machine before making any changes (this step is not required but I highly recommended).

2- Open your project.

3- Slow double click or hit enter on the Project name (blue top icon) and rename it to whatever you like.

NOTE: After you rename the project and press ‘enter’ it will suggest to automatically change all project-name-related entries and will allow you to de-select some of them if you want. Select all of them and click ok.

4- Rename the Scheme

a) Click the menu right next to the stop button and select Manage Schemes.

b) Single-slow-click or hit enter on the old name scheme and rename it to whatever you like.

c) Click ok.

5 - Build and run to make sure it works.

NOTES: At this point all of the important project files should be renamed except the comments in the classes created when the project was created nor the source folder. Next we will rename the folder in the file system.

6- Close the project.

7- Rename the main and the source folder.

8- Right click the project bundle .xcodeproj file and select “Show Package Contents” from the context menu. Open the .pbxproj file with any text editor.

9- Search and replace any occurrence of the original folder name with the new folder name.

10- Save the file.

11- Open XCode project, test it.

12- Done.

EDIT 10/11/19:

There is a tool to rename projects in Xcode I haven't tried it enough to comment on it. https://github.com/appculture/xcode-project-renamer

You need a combination of Math.Abs on X-Y and a value to compare with.

You can use following Extension method approach

public static class DoubleExtensions
    {
        const double _3 = 0.001;
        const double _4 = 0.0001;
        const double _5 = 0.00001;
        const double _6 = 0.000001;
        const double _7 = 0.0000001;

        public static bool Equals3DigitPrecision(this double left, double right)
        {
            return Math.Abs(left - right) < _3;
        }

        public static bool Equals4DigitPrecision(this double left, double right)
        {
            return Math.Abs(left - right) < _4;
        }

        ...

Since you rarely call methods on double except ToString I believe its pretty safe extension.

Then you can compare x and y like

if(x.Equals4DigitPrecision(y))

In addition to the answers posted here, make sure you read this article:

http://24ways.org/2009/rock-solid-html-emails

You might want to check your matplotlib version.

Somehow I installed a dev version of matplotlib which caused the issue. A downgrade to stable release fixed it.

One can also can try python -v -c 'import YOUR_PACKAGE' 2>&1 | less to see where the issue occurred and if the lines above error can give you some hints.

If you want to know if it's an empty string use === instead of ==.

if(variable === "") {
}

This is because === will only return true if the values on both sides are of the same type, in this case a string.

for example: (false == "") will return true, and (false === "") will return false.

Yes, Just be careful if you are also iterating over the list, because in this case you will need to synchronize on it. From the Javadoc:

It is imperative that the user manually synchronize on the returned list when iterating over it:

List list = Collections.synchronizedList(new ArrayList());
    ...
synchronized (list) {
    Iterator i = list.iterator(); // Must be in synchronized block
    while (i.hasNext())
        foo(i.next());
}

Or, you can use CopyOnWriteArrayList which is slower for writes but doesn't have this issue.

Shortest answer:

$('#titlee a').click();

Format strings can make hexdump behave exactly as you want it to (no whitespace at all, byte by byte):

hexdump -ve '1/1 "%.2x"'

1/1 means "each format is applied once and takes one byte", and "%.2x" is the actual format string, like in printf. In this case: 2-character hexadecimal number, leading zeros if shorter.

I had the same error when I tried to migrate Drupal database to a new local apache server(I am using XAMPP on Windows machine). Actually I don't know the meaning of this error, but after trying steps below, I imported the database without errors. Hope this could help:

Changing php.ini at C:\xampp\php\php.ini

max_execution_time = 600
max_input_time = 600
memory_limit = 1024M
post_max_size = 1024M

Changing my.ini at C:\xampp\mysql\bin\my.ini

max_allowed_packet = 1024M

Look at the keys and indentation in your print_r:

echo $myarray[0]['email'];

echo $myarray[0]['gender'];

...etc

The class which implements KeyListener interface becomes our custom key event listener. This listener can not directly listen the key events. It can only listen the key events through intermediate objects such as JFrame. So

1. Make one Key listener class as

   class MyListener implements KeyListener{
   
      // override all the methods of KeyListener interface.
   }
   

2. Now our class MyKeyListener is ready to listen the key events. But it can not directly do so.

3. Create any object like JFrame object through which MyListener can listen the key events. for that you need to add MyListener object to the JFrame object.

   JFrame f=new JFrame();
   f.addKeyListener(new MyKeyListener);
   

An easy, albeit messy workaround to this would be to nest a second "holder" class inside of your main class, and use it to hold your data.

public class Whatever<Thing>{
    private class Holder<OtherThing>{
        OtherThing thing;
    }
    public Holder<Thing>[] arrayOfHolders = new Holder<Thing>[10]
}

I've just replied to the related question given by Vanuan (Eclipse CDT: Unresolved inclusion of stl header), and this is my answer :

You could also try use "CDT GCC Built-in Compiler Settings". Go to the project properties > C/C++ General > Preprocessor Include Path > Providers tab then check "CDT GCC Built-in Compiler Settings" if it is not.

None of the other solutions (play with include path, etc) worked for me for the type 'string', but this one fixed it.

First of all, from __future__ import print_function needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print as a function now. That's the whole point of from __future__ import print_function; to bring the print function from Python 3 into Python 2.6+.

from __future__ import print_function

import sys, os, time

for x in range(0,10):
    print(x, sep=' ', end='')  # No need for sep here, but okay :)
    time.sleep(1)

__future__ statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:

A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.

The documentation also mentions that the only things that can precede a __future__ statement are the module docstring, comments, blank lines, and other future statements.

This worked for me, allowing both negative and positive numbers:

 \-*\d+

If using C#:

Regex.Match(someString, @"\-*\d+").Value;

SELECT * FROM testcases1 t WHERE NOT EXISTS ( SELECT 1
FROM executions1 i WHERE t.tc_id = i.tc_id and t.pro_id=i.pro_id and pro_id=7 and version_id=5 ) and pro_id=7 ;

Here testcases1 table contains all datas and executions1 table contains some data among testcases1 table. I am retrieving only the datas which are not present in exections1 table. ( and even I am giving some conditions inside that you can also give.) specify condition which should not be there in retrieving data should be inside brackets.

You should be able to use the Application class in the same way as Winform apps do. Probably the easiest way to start a new project is to do what Marc suggested: create a new Winform project, and then change it in the options to a console application

This command with --user 0 do the job:

adb uninstall --user 0 <package_name>

There's also the QueryString module's parse() method:

var http = require('http'),
    queryString = require('querystring');

http.createServer(function (oRequest, oResponse) {

    var oQueryParams;

    // get query params as object
    if (oRequest.url.indexOf('?') >= 0) {
        oQueryParams = queryString.parse(oRequest.url.replace(/^.*\?/, ''));

        // do stuff
        console.log(oQueryParams);
    }

    oResponse.writeHead(200, {'Content-Type': 'text/plain'});
    oResponse.end('Hello world.');

}).listen(1337, '127.0.0.1');

For any file path with space, simply put them in double quotations will work in Windows Powershell. For example, if you want to go to Program Files directory, instead of use

PS C:\> cd Program Files

which will induce error, simply use the following will solve the problem:

PS C:\> cd "Program Files"

Jsel is awesome and is based on a real XPath engine. It allows you to create XPath expressions to find any type of JavaScript data, not just objects (strings too).

You can create custom schemas and mappings to give you complete control over how your data is walkable by the XPath engine. A schema is a way of defining how elements, children, attributes, and node values are defined in your data. Then you can create your own expressions to suit.

Given you had a variable called data which contained the JSON from the question, you could use jsel to write:

jsel(data).select("//*[@id=3]")

This will return any node with an id attribute of 3. An attribute is any primitive (string, number, date, regex) value within an object.

For Full like you can user :

$this->db->like('title',$query);

For %$query you can use

$this->db->like('title', $query, 'before');

and for $query% you can use

$this->db->like('title', $query, 'after');

You can invoke reflections and also, set order of sequence for getter for values through annotations

Above answer won't work if the Display class will not work then you can get the width and height by below method.

private static final int WIDTH_INDEX = 0;
private static final int HEIGHT_INDEX = 1;

    public static int[] getScreenSize(Context context) {
        int[] widthHeight = new int[2];
        widthHeight[WIDTH_INDEX] = 0;
        widthHeight[HEIGHT_INDEX] = 0;

        try {
            WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
            Display display = windowManager.getDefaultDisplay();

            Point size = new Point();
            display.getSize(size);
            widthHeight[WIDTH_INDEX] = size.x;
            widthHeight[HEIGHT_INDEX] = size.y;

            if (!isScreenSizeRetrieved(widthHeight))
            {
                DisplayMetrics metrics = new DisplayMetrics();
                display.getMetrics(metrics);
                widthHeight[0] = metrics.widthPixels;
                widthHeight[1] = metrics.heightPixels;
            }

            // Last defense. Use deprecated API that was introduced in lower than API 13
            if (!isScreenSizeRetrieved(widthHeight)) {
                widthHeight[0] = display.getWidth(); // deprecated

        return widthHeight;

Here is another way...

It adds "others" to the enum definition of the column "rtipo" of the table "firmas".

set @new_enum = 'others';
set @table_name = 'firmas';
set @column_name = 'rtipo';
select column_type into @tmp from information_schema.columns 
  where table_name = @table_name and column_name=@column_name;
set @tmp = insert(@tmp, instr(@tmp,')'), 0, concat(',\'', @new_enum, '\'') );
set @tmp = concat('alter table ', @table_name, ' modify ', @column_name, ' ', @tmp);
prepare stmt from @tmp;
execute stmt;
deallocate prepare stmt;

Check the libs version requirements. The lib might be trying to call a method from from a higher Android version. Try adding the apps compatability libs.

When all else fails try switching from a Gradle build to an Eclipse build.

Delete and restructure your folders to the eclipse style and delete everything but your code. Then reload the project with your libs.

Once it runs go back to Gradle, if you wish.

I'd rather use more convenient itemSelect event. With this event you can use org.primefaces.event.SelectEvent objects in your listener.

<p:selectOneMenu ...>
    <p:ajax event="itemSelect" 
        update="messages"
        listener="#{beanMB.onItemSelectedListener}"/>
</p:selectOneMenu>

With such listener:

public void onItemSelectedListener(SelectEvent event){
    MyItem selectedItem = (MyItem) event.getObject();
    //do something with selected value
}

Try this:

RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteRule ^(.*)$ %{HTTP_HOST}$1 [C]
RewriteRule ^www\.(.*)$ http://$1 [L,R=301]

If the host starts with www, we stick the whole host onto the start of the URL, then take off the "www."

This problem occures when you use your service via other application.If application has config file just add your service config information to this file. In my situation there wasn't any config file so I use this technique and it worked fine.Just store url address in application,read it and using BasicHttpBinding() method send it to service application as parameter.This is simple demonstration how I did it:

Configuration config = new Configuration(dataRowSet[0]["ServiceUrl"].ToString());

var remoteAddress = new System.ServiceModel.EndpointAddress(config.Url);


SimpleService.PayPointSoapClient client =

I pasted your code into test project, added about 20 items and I get usable scroll bars, no problem, and they work as expected. When I only add a couple items (such that scrolling is unnecessary) I get no usable scrollbar. Could this be the case? that you are not adding enough items?

If you remove the ScrollViewer.VerticalScrollBarVisibility="Visible" then the scroll bars only appear when you have need of them.

For decimals:

DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setGroupingSeparator(' ');
DecimalFormat dfDecimal = new DecimalFormat("###########0.00###");
dfDecimal.setDecimalFormatSymbols(symbols);
dfDecimal.setGroupingSize(3);
dfDecimal.setGroupingUsed(true);
System.out.println(dfDecimal.format(number));

Try to pass value a and compare using the equals method like this:

public static void main(String str[]) {

    boolean b = str[0].equals("a");

    System.out.println(b);

}

I tried a few times and finally solved the problem by uninstalling several times the VS2010. I think I hadn't uninstalled all the files and that's why it didn't work for the first time.

In the installation of VS2012, it is said that if you have VS2010 SP1 you can't work on the same project in both programs. It is recommended to have only one program.

Thanks!

Order By is applied after union, so just add an order by clause at the end of the statements:

Select id,name,age
From Student
Where age < 15
Union
Select id,name,age
From Student
Where Name like '%a%'
Order By name

import os

for filename in os.listdir("C:\\temp"):
    print  filename

PHP has some image processing functions along with the imagecreatefrompng and imagejpeg function. The first will create an internal representation of a PNG image file while the second is used to save that representation as JPEG image file.

Have a look at: Greybox

It's an awesome version of lightbox that supports forms, external web pages as well as the traditional images and slideshows. It works perfectly from a link on a webpage.

You will find many information on how to use Greybox and also some great examples. Cheers Kara

To copy your public key to the clipboard

cat ~/.ssh/id_rsa.pub | pbcopy

This pipes the output of the file to pbcopy.

I call *args "star args" or "varargs" and **kwargs "keyword args".

In the other question I suggested autoexnt. That is also possible in this situation. Just set the service to run manually (ie not automatic at startup). When you want to run your batch, modify the autoexnt.bat file to call the batch file you want, and start the autoexnt service.

The batchfile to start this, can look like this (untested):

echo call c:\path\to\batch.cmd %* > c:\windows\system32\autoexnt.bat
net start autoexnt

Note that batch files started this way run as the system user, which means you do not have access to network shares automatically. But you can use net use to connect to a remote server.

You have to download the Windows 2003 Resource Kit to get it. The Resource Kit can also be installed on other versions of windows, like Windows XP.

Bart Kiers, your regex has a couple issues. The best way to do that is this:

(.*[a-z].*)       // For lower cases
(.*[A-Z].*)       // For upper cases
(.*\d.*)          // For digits

In this way you are searching no matter if at the beginning, at the end or at the middle. In your have I have a lot of troubles with complex passwords.

Have you considered not computing the file size and just growing the array if necessary? Here's an example (with error checking ommitted):

#define CHUNK 1024

/* Read the contents of a file into a buffer.  Return the size of the file 
 * and set buf to point to a buffer allocated with malloc that contains  
 * the file contents.
 */
int read_file(FILE *fp, char **buf) 
{
  int n, np;
  char *b, *b2;

  n = CHUNK;
  np = n;
  b = malloc(sizeof(char)*n);
  while ((r = fread(b, sizeof(char), CHUNK, fp)) > 0) {
    n += r;
    if (np - n < CHUNK) { 
      np *= 2;                      // buffer is too small, the next read could overflow!
      b2 = malloc(np*sizeof(char));
      memcpy(b2, b, n * sizeof(char));
      free(b);
      b = b2;
    }
  }
  *buf = b;
  return n;
}

This has the advantage of working even for streams in which it is impossible to get the file size (like stdin).

To specify a directory to search for (binary) libraries, you just use -L:

-L/data[...]/lib

To specify the actual library name, you use -l:

-lfoo  # (links libfoo.a or libfoo.so)

To specify a directory to search for include files (different from libraries!) you use -I:

-I/data[...]/lib

So I think what you want is something like

g++ -g -Wall -I/data[...]/lib testing.cpp fileparameters.cpp main.cpp -o test

These compiler flags (amongst others) can also be found at the GNU GCC Command Options manual:

• 3.16 Options for Directory Search

I also think the original object should not be modified. So to save future manpower here's a combined solution based on Jason Harwig's and Tahir Hasan answers:

Date.prototype.addHours= function(h){
    var copiedDate = new Date();
    copiedDate.setTime(this.getTime() + (h*60*60*1000)); 
    return copiedDate;
}

//Response being your httpwebresponse
Dim str_StatusCode as String = CInt(Response.StatusCode)
Console.Writeline(str_StatusCode)

I think the new preferred way might be to use IDataErrorInfo

Collected ideas from multiple C++ sources and put it into a nice, still quite simple example for getters/setters in C++:

class Canvas { public:
    void resize() {
        cout << "resize to " << width << " " << height << endl;
    }

    Canvas(int w, int h) : width(*this), height(*this) {
        cout << "new canvas " << w << " " << h << endl;
        width.value = w;
        height.value = h;
    }

    class Width { public:
        Canvas& canvas;
        int value;
        Width(Canvas& canvas): canvas(canvas) {}
        int & operator = (const int &i) {
            value = i;
            canvas.resize();
            return value;
        }
        operator int () const {
            return value;
        }
    } width;

    class Height { public:
        Canvas& canvas;
        int value;
        Height(Canvas& canvas): canvas(canvas) {}
        int & operator = (const int &i) {
            value = i;
            canvas.resize();
            return value;
        }
        operator int () const {
            return value;
        }
    } height;
};

int main() {
    Canvas canvas(256, 256);
    canvas.width = 128;
    canvas.height = 64;
}

Output:

new canvas 256 256
resize to 128 256
resize to 128 64

You can also directly use jQuery.

$('#myModal').is(':visible');

Use //NOSONAR on the line you get warning if it is something you cannot help your code with. It works!

You can use following snippet to check Internet Connection.

It will useful both way that you can check which Type of NETWORK Connection is available so you can do your process on that way.

You just have to copy following class and paste directly in your package.

/**
 * @author Pratik Butani
 */
public class InternetConnection {

    /**
     * CHECK WHETHER INTERNET CONNECTION IS AVAILABLE OR NOT
     */
    public static boolean checkConnection(Context context) {
        final ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

        if (connMgr != null) {
            NetworkInfo activeNetworkInfo = connMgr.getActiveNetworkInfo();

            if (activeNetworkInfo != null) { // connected to the internet
                // connected to the mobile provider's data plan
                if (activeNetworkInfo.getType() == ConnectivityManager.TYPE_WIFI) {
                    // connected to wifi
                    return true;
                } else return activeNetworkInfo.getType() == ConnectivityManager.TYPE_MOBILE;
            }
        }
        return false;
    }
}

Now you can use like:

if (InternetConnection.checkConnection(context)) {
    // Its Available...
} else {
    // Not Available...
}

DON'T FORGET to TAKE Permission :) :)

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

You can modify based on your requirement.

Thank you.

Try dir /b, for bare format.

dir /? will show you documentation of what you can do with the dir command. Here is the output from my Windows 7 machine:

C:\>dir /?
Displays a list of files and subdirectories in a directory.

DIR [drive:][path][filename] [/A[[:]attributes]] [/B] [/C] [/D] [/L] [/N]
  [/O[[:]sortorder]] [/P] [/Q] [/R] [/S] [/T[[:]timefield]] [/W] [/X] [/4]

  [drive:][path][filename]
              Specifies drive, directory, and/or files to list.

  /A          Displays files with specified attributes.
  attributes   D  Directories                R  Read-only files
               H  Hidden files               A  Files ready for archiving
               S  System files               I  Not content indexed files
               L  Reparse Points             -  Prefix meaning not
  /B          Uses bare format (no heading information or summary).
  /C          Display the thousand separator in file sizes.  This is the
              default.  Use /-C to disable display of separator.
  /D          Same as wide but files are list sorted by column.
  /L          Uses lowercase.
  /N          New long list format where filenames are on the far right.
  /O          List by files in sorted order.
  sortorder    N  By name (alphabetic)       S  By size (smallest first)
               E  By extension (alphabetic)  D  By date/time (oldest first)
               G  Group directories first    -  Prefix to reverse order
  /P          Pauses after each screenful of information.
  /Q          Display the owner of the file.
  /R          Display alternate data streams of the file.
  /S          Displays files in specified directory and all subdirectories.
  /T          Controls which time field displayed or used for sorting
  timefield   C  Creation
              A  Last Access
              W  Last Written
  /W          Uses wide list format.
  /X          This displays the short names generated for non-8dot3 file
              names.  The format is that of /N with the short name inserted
              before the long name. If no short name is present, blanks are
              displayed in its place.
  /4          Displays four-digit years

Switches may be preset in the DIRCMD environment variable.  Override
preset switches by prefixing any switch with - (hyphen)--for example, /-W.

I had tried all of the above solutions and still no luck. I had heard people installing visual studio on their build servers to fix it, but I only had 5gb of free spaces so I just copied C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio to my build server and called it a day. Started working after that, using team city 9.x and visual studio 2013.

I'm on Windows and have used 4 methods: SFTP, WinSCP, Unison and Sublime Text on Linux with X11 forwarding over SSH to Windows (yes you can do this without messy configs and using a free tool).

The fourth way is the best if you can install software on your Linux machine.

The fourth way:

MobaXterm

1. Install MobaXterm on Windows
2. SSH to your Linux box from MobaXterm
3. On your linux box, install Sublime Text 3. Here's how to on Ubuntu
4. At the command prompt, start sublime with subl
5. That's it! You now have sublime text running on Linux, but with its window running on your Windows desktop. This is possible because MobaXterm handles the X11 forwarding over SSH for you so you don't have to do anything funky to get it going. There might be a teeny amount of a delay, but your files will never be out of sync, because you're editing them right on the Linux machine.

Note: When invoking subl if it complains for a certain library - ensure you install them to successfully invoke sublimetext from mobaxterm.

If you can't install software on your Linux box, the best is Unison. Why?

• It's free
• It's fast
• It's reliable and doesn't care which editor you use
• You can create custom ignore lists

SFTP

Setup: Install the SFTP Sublime Text package. This package requires a license.

1. Create a new folder
2. Open it as a Sublime Text Project.
3. In the sidebar, right click on the folder and select Map Remote.
4. Edit the sftp-config.json file
5. Right click the folder in step 1 select download.
6. Work locally.

In the sftp-config, I usually set:

"upload_on_save": true,
"sync_down_on_open": true,

This, in addition to an SSH terminal to the machine gives me a fairly seamless remote editing experience.

WinSCP

1. Install and run WinSCP
2. Go to Preferences (Ctrl+Alt+P) and click on Transfer, then on Add. Name the preset.
3. Set the transfer mode to binary (you don't want line conversions)
4. Set file modification to "No change"
5. Click the Edit button next to File Mask and setup your include and exclude files and folders (useful for when you have a .git/.svn folder present or you want to exclude build products from being synchronized).
6. Click OK
7. Connect to your remote server and navigate to the folder of interest
8. Choose an empty folder on your local machine.
9. Select your newly created Transfer settings preset.
10. Finally, hit Ctrl+U (Commands > Keep remote directory up to date) and make sure "Synchronize on start" and "Update subdirectories" are checked.

From then on, WinSCP will keep your changes synchronized.

Work in the local folder using SublimeText. Just make sure that Sublime Text is set to guess the line endings from the file that is being edited.

Unison

I have found that if source tree is massive (around a few hundred MB with a deep hierarchy), then the WinSCP method described above might be a bit slow. You can get much better performance using Unison. The down side is that Unison is not automatic (you need to trigger it with a keypress) and requires a server component to be running on your linux machine. The up side is that the transfers are incredibly fast, it is very reliable and ignoring files, folders and extensions are incredibly easy to setup.

A multiple select is really just a select with a multiple attribute. With that in mind, it should be as easy as...

Form::select('sports[]', $sports, null, array('multiple'))

The first parameter is just the name, but post-fixing it with the [] will return it as an array when you use Input::get('sports').

The second parameter is an array of selectable options.

The third parameter is an array of options you want pre-selected.

The fourth parameter is actually setting this up as a multiple select dropdown by adding the multiple property to the actual select element..

I have got kept a handy helper method to take care of this based on one answer posted above:

Imports:

import com.google.i18n.phonenumbers.NumberParseException
import com.google.i18n.phonenumbers.PhoneNumberUtil

Function:

    fun parseCountryCode( phoneNumberStr: String?): String {
        val phoneUtil = PhoneNumberUtil.getInstance()
        return try {
            // phone must begin with '+'
            val numberProto = phoneUtil.parse(phoneNumberStr, "")
            numberProto.countryCode.toString()
        } catch (e: NumberParseException) {
            ""
        }
    }

I see a lot of "px" discussion but no one is talking percentages which is the fixed number you want to calculate by.

22.37% is the key percentage here. Multiply any of the image sizes mentioned above in by 0.2237 and you will get the correct pixel radius for that size.

Before iOS 8, Apple used less rounding, using 15.625%.

EDIT: Thanks @Chris Prince for commenting with the iOS 8/9/10 radius percentage: 22.37%

the OOP way without any strings as entities names Swift 3+, Xcode 10+

func batchDelete<T>(in context: NSManagedObjectContext, fetchRequest: NSFetchRequest<T>) throws {
    guard let request = fetchRequest as? NSFetchRequest<NSFetchRequestResult> else {
        throw ErrorService.defaultError
    }
    let batchDeleteRequest = NSBatchDeleteRequest(fetchRequest: request)
    do {
        try context.execute(batchDeleteRequest)
    } catch {
        throw error
    }
}

then just call in do/catch block

    let fetchRequest: NSFetchRequest<YourEntity> = YourEntity.fetchRequest()
    do {
        let data = try context.fetch(fetchRequest)
        if data.count > 0 {
            try self.batchDelete(in: context, fetchRequest: fetchRequest)
        }
    } catch {
        // throw error
    }

Size of some float types may exceed the size of int. This example shows a safe conversion of any float type to int using the int safeFloatToInt(const FloatType &num); function:

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

template <class FloatType>
int safeFloatToInt(const FloatType &num) {
   //check if float fits into integer
   if ( numeric_limits<int>::digits < numeric_limits<FloatType>::digits) {
      // check if float is smaller than max int
      if( (num < static_cast<FloatType>( numeric_limits<int>::max())) &&
          (num > static_cast<FloatType>( numeric_limits<int>::min())) ) {
         return static_cast<int>(num); //safe to cast
      } else {
        cerr << "Unsafe conversion of value:" << num << endl;
        //NaN is not defined for int return the largest int value
        return numeric_limits<int>::max();
      }
   } else {
      //It is safe to cast
      return static_cast<int>(num);
   }
}
int main(){
   double a=2251799813685240.0;
   float b=43.0;
   double c=23333.0;
   //unsafe cast
   cout << safeFloatToInt(a) << endl;
   cout << safeFloatToInt(b) << endl;
   cout << safeFloatToInt(c) << endl;
   return 0;
}

Result:

Unsafe conversion of value:2.2518e+15
2147483647
43
23333

For Java 8 this is one right way to do it:

Files.walk(new File("D:/temp").toPath())
                .map(f -> f.toFile())
                .filter(f -> f.isFile())
                .mapToLong(f -> f.length()).sum()

It is important to filter out all directories, because the length method isn't guaranteed to be 0 for directories.

At least this code delivers the same size information like Windows Explorer itself does.

I have a simple workaround.

Suppose your URI has a string stringdata that is too long. You can simply break it into a number of parts depending on the limits of your server. Then submit the first one, in my case to write a file. Then submit the next ones to append to previously added data.

If the behavior of for(... in ...) is acceptable/necessary for your purposes, you can tell tslint to allow it.

in tslint.json, add this to the "rules" section.

"forin": false

Otherwise, @Maxxx has the right idea with

for (const field of Object.keys(this.formErrors)) {

Use a negative lookahead and a negative lookbehind:

> s = "one two 3.4 5,6 seven.eight nine,ten"
> parts = re.split('\s|(?<!\d)[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten']

In other words, you always split by \s (whitespace), and only split by commas and periods if they are not followed (?!\d) or preceded (?<!\d) by a digit.

DEMO.

EDIT: As per @verdesmarald comment, you may want to use the following instead:

> s = "one two 3.4 5,6 seven.eight nine,ten,1.2,a,5"
> print re.split('\s|(?<!\d)[,.]|[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten', '1.2', 'a', '5']

This will split "1.2,a,5" into ["1.2", "a", "5"].

DEMO.

A canvas element with some JavaScript would work great.

In fact, Signature Pad (a jQuery plugin) already has this implemented.

If you used a raw socket (SOCK_RAW) and re-implemented TCP in userland, I think the answer is limited in this case only by the number of (local address, source port, destination address, destination port) tuples (~2^64 per local address).

It would of course take a lot of memory to keep the state of all those connections, and I think you would have to set up some iptables rules to keep the kernel TCP stack from getting upset &/or responding on your behalf.

I wanted a more exact and useful answer to this question. Here's the real answer (adjust accordingly if you want a byte array specifically; obviously the math will be off by a factor of 8 bits : 1 byte):

class BitArray {
  constructor(bits = 0) {
    this.uints = new Uint32Array(~~(bits / 32));
  }

  getBit(bit) {
    return (this.uints[~~(bit / 32)] & (1 << (bit % 32))) != 0 ? 1 : 0;
  }

  assignBit(bit, value) {
    if (value) {
      this.uints[~~(bit / 32)] |= (1 << (bit % 32));
    } else {
      this.uints[~~(bit / 32)] &= ~(1 << (bit % 32));
    }
  }

  get size() {
    return this.uints.length * 32;
  }

  static bitsToUints(bits) {
    return ~~(bits / 32);
  }
}

Usage:

let bits = new BitArray(500);
for (let uint = 0; uint < bits.uints.length; ++uint) {
  bits.uints[uint] = 457345834;
}
for (let bit = 0; bit < 50; ++bit) {
  bits.assignBit(bit, 1);
}
str = '';
for (let bit = bits.size - 1; bit >= 0; --bit) {
  str += bits.getBit(bit);
}
str;

Output:

"00011011010000101000101100101010
 00011011010000101000101100101010
 00011011010000101000101100101010

Note: This class is really slow to e.g. assign bits (i.e. ~2s per 10 million assignments) if it's created as a global variable, at least in the Firefox 76.0 Console on Linux... If, on the other hand, it's created as a variable (i.e. let bits = new BitArray(1e7);), then it's blazingly fast (i.e. ~300ms per 10 million assignments)!

For more info, see here:

• "How do you set, clear and toggle a single bit in JavaScript?": https://stackoverflow.com/a/1436448/1599699

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays
• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint32Array

Note that I used Uint32Array because there's no way to directly have a bit/byte array (that you can interact with directly) and because even though there's a BigUint64Array, JS only supports 32 bits:

Bitwise operators treat their operands as a sequence of 32 bits

...

The operands of all bitwise operators are converted to...32-bit integers

window.location.href returns the location of the current page.

top.location.href (which is an alias of window.top.location.href) returns the location of the topmost window in the window hierarchy. If a window has no parent, top is a reference to itself (in other words, window === window.top).

top is useful both when you're dealing with frames and when dealing with windows which have been opened by other pages. For example, if you have a page called test.html with the following script:

var newWin=window.open('about:blank','test','width=100,height=100');
newWin.document.write('<script>alert(top.location.href);</script>');

The resulting alert will have the full path to test.html – not about:blank, which is what window.location.href would return.

To answer your question about redirecting, go with window.location.assign(url);

Actually, it will takes 101 bytes.

I think what you are looking for is string.count

"Allowed Hello Hollow".count('ll')
>>> 3

Hope this helps
NOTE: this only captures non-overlapping occurences

You can user below link to compare 2 dates without time :

private bool DateGreaterOrEqual(DateTime dt1, DateTime dt2)
        {
            return DateTime.Compare(dt1.Date, dt2.Date) >= 0;
        }

private bool DateLessOrEqual(DateTime dt1, DateTime dt2)
        {
            return DateTime.Compare(dt1.Date, dt2.Date) <= 0;
        }

the Compare function return 3 different values: -1 0 1 which means dt1>dt2, dt1=dt2, dt1

querySelectorAll with modern enumeration

polls = document.querySelectorAll('[id ^= "poll-"]');
Array.prototype.forEach.call(polls, callback);

function callback(element, iterator) {
    console.log(iterator, element.id);
}

The first line selects all elements which id starts with the string poll-. The second line evokes the enumeration and a callback function.

Try to use

ng g component plainsight/some-name.component.ts

Or try it manually, if you feel more comfortable.

Your code is in the default package, i.e. you have source all files in src/main/java with no custom package. I strongly suggest u to create package n then place your source file in it.

Ex-
 src->
     main->
          java->
                com.myfirst.example
                   Example.java
                com.myfirst.example.controller
                   PersonController.java
                com.myfirst.example.repository
                  PersonRepository.java
                com.myfirst.example.model
                   Person.java

I hope it will resolve your problem.

This is the best option to cast/convert list of generic object to list of string.

object valueList;
List<string> list = ((IList)valueList).Cast<object>().Select(o => o.ToString()).ToList();

Unchecked all Device orientation and checked only "Requires full screen". Its working properly

Don't use MD5 as it is insecure. I would recommend using SHA or bcrypt with a salt:

SHA256('".$password."')

Difference between Thread and Process?

A process is an executing instance of an application and A thread is a path of execution within a process. Also, a process can contain multiple threads.It’s important to note that a thread can do anything a process can do. But since a process can consist of multiple threads, a thread could be considered a ‘lightweight’ process. Thus, the essential difference between a thread and a process is the work that each one is used to accomplish. Threads are used for small tasks, whereas processes are used for more ‘heavyweight’ tasks – basically the execution of applications.

Another difference between a thread and a process is that threads within the same process share the same address space, whereas different processes do not. This allows threads to read from and write to the same data structures and variables, and also facilitates communication between threads. Communication between processes – also known as IPC, or inter-process communication – is quite difficult and resource-intensive.

Here’s a summary of the differences between threads and processes:

1. Threads are easier to create than processes since they don't require a separate address space.

2. Multithreading requires careful programming since threads share data strucures that should only be modified by one thread at a time. Unlike threads, processes don't share the same address space.

3. Threads are considered lightweight because they use far less resources than processes.

4. Processes are independent of each other. Threads, since they share the same address space are interdependent, so caution must be taken so that different threads don't step on each other.
   This is really another way of stating #2 above.

5. A process can consist of multiple threads.

https://docs.oracle.com/javase/tutorial/reflect/class/classMembers.html also has charts for locating methods and constructors.

You create the relationships the other way around; add foreign keys to the Person type to create a Many-to-One relationship:

class Person(models.Model):
    name = models.CharField(max_length=50)
    birthday = models.DateField()
    anniversary = models.ForeignKey(
        Anniversary, on_delete=models.CASCADE)
    address = models.ForeignKey(
        Address, on_delete=models.CASCADE)

class Address(models.Model):
    line1 = models.CharField(max_length=150)
    line2 = models.CharField(max_length=150)
    postalcode = models.CharField(max_length=10)
    city = models.CharField(max_length=150)
    country = models.CharField(max_length=150)

class Anniversary(models.Model):
    date = models.DateField()

Any one person can only be connected to one address and one anniversary, but addresses and anniversaries can be referenced from multiple Person entries.

Anniversary and Address objects will be given a reverse, backwards relationship too; by default it'll be called person_set but you can configure a different name if you need to. See Following relationships "backward" in the queries documentation.

As an alternative, you could add it as a script parameter for input as part of script execution

 param(
      [Parameter(Mandatory = $True,valueFromPipeline=$true)][String] $value1,
      [Parameter(Mandatory = $True,valueFromPipeline=$true)][String] $value2
      )

Starting in iOS 6, you can use

-tableView:shouldHighlightRowAtIndexPath:

If you return NO, it disables both the selection highlighting and the storyboard triggered segues connected to that cell.

The method is called when a touch comes down on a row. Returning NO to that message halts the selection process and does not cause the currently selected row to lose its selected look while the touch is down.

UITableViewDelegate Protocol Reference

Try this Code

var app = angular.module('myapp', []);
  app.controller('testController', function ($scope, $http) {
       $scope.init = function(){           
       alert($scope.testInput);
   };});

<body ng-app="myapp">_x000D_
      <div ng-controller='testController' data-ng-init="testInput='value'; init();" class="col-sm-9 col-lg-9" >_x000D_
      </div>_x000D_
</body>

I've written a library that is up-to-date, since all the other answers are outdated:

You can cast like this:

return this.createMarkerStyle(<MarkerSymbolInfo> symbolInfo);

Or like this if you want to be compatible with tsx mode:

return this.createMarkerStyle(symbolInfo as MarkerSymbolInfo);

Just remember that this is a compile-time cast, and not a runtime cast.

If you're fetching a single item only then, you need use select before your FirstOrDefault()/SingleOrDefault(). And you can use anonymous object of the required properties.

var name = dbContext.MyTable.Select(x => new { x.UserId, x.Name }).FirstOrDefault(x => x.UserId == 1)?.Name;

Above query will be converted to this:

Select Top (1) UserId, Name from MyTable where UserId = 1;

For multiple items you can simply chain Select after Where:

var names = dbContext.MyTable.Where(x => x.UserId > 10).Select(x => x.Name);

Use anonymous object inside Select if you need more than one properties.

What version of the framework? With 3.5 you could presumably use:

List<ManagementObject> managementList = managementObjects.Cast<ManagementObject>().ToList();

(edited to remove simpler version; I checked and ManagementObjectCollection only implements the non-generic IEnumerable form)
