Ideone supports Python 2.6 and Python 3

Short (un-precise) definition:

Compiled language: Entire program is translated to machine code at once, then the machine code is run by the CPU.

Interpreted language: Program is read line-by-line and as soon as a line is read the machine instructions for that line are executed by the CPU.

But really, few languages these days are purely compiled or purely interpreted, it often is a mix. For a more detailed description with pictures, see this thread:

What is the difference between compilation and interpretation?

Or my later blog post:

Up Arrow works only in Python command line.

In IDLE (Python GUI) the defaults are: Alt-p : retrieves previous command matching what you have typed. Alt-n : retrieves next... In Python 2.7.9 for example, you can see/change the Action Keys selecting: Options -> Configure IDLE -> (Tab) Keys

You can use find

find . -type d > output.txt

or tree

tree -d > output.txt

tree, If not installed on your system.

If you are using ubuntu

sudo apt-get install tree

If you are using mac os.

brew install tree

you need just in scss varible

$input-btn-focus-width:       .05rem !default;

Background color of views (navigator, console, tasks etc) is set according to the desktop (system) settings. On Linux/GNome I changed System/Preferences/Appeareance to change this color.

Editor colors are set chaotically by different editors, search for background in eclipse preferences to find different options. One easy way to get beautiful dark (and not only dark) themes is to install Afae plugin, and then pick theme within its preferences (twilight theme is beautiful, for example) - again, eclipse prefs, Afae group. Of course this applies only when you edit with Afae.

I don't think there is anything you can do to avoid what you are already doing, however, if you are building the table on the client with javascript, you can always add the style rules dynamically, so you can allow for any number of columns without cluttering up your css file with all those rules. See http://www.hunlock.com/blogs/Totally_Pwn_CSS_with_Javascript if you don't know how to do this.

Edit: For your "sticky" toggle, you should just append class names rather than replacing them. For instance, you can give it a class name of "hide2 hide3" etc. I don't think you really need the "show" classes, since that would be the default. Libraries like jQuery make this easy, but in the absence, a function like this might help:

var modifyClassName = function (elem, add, string) {
var s = (elem.className) ? elem.className : "";
var a = s.split(" ");
if (add) {
  for (var i=0; i<a.length; i++) {
      if (a[i] == string) {
          return;
          }
      }
  s += " " + string;
  }
else {
    s = "";
    for (var i=0; i<a.length; i++) {
        if (a[i] != string)
            s += a[i] + " "; 
        }
    }
elem.className = s;
}

To properly achieve this, you'd be better off by checking the mime type.

function get_mime($file) {
  if (function_exists("finfo_file")) {
    $finfo = finfo_open(FILEINFO_MIME_TYPE); // return mime type ala mimetype extension
    $mime = finfo_file($finfo, $file);
    finfo_close($finfo);
    return $mime;
  } else if (function_exists("mime_content_type")) {
    return mime_content_type($file);
  } else if (!stristr(ini_get("disable_functions"), "shell_exec")) {
    // http://stackoverflow.com/a/134930/1593459
    $file = escapeshellarg($file);
    $mime = shell_exec("file -bi " . $file);
    return $mime;
  } else {
    return false;
  }
}
//pass the file name as
echo(get_mime($_FILES['file_name']['tmp_name']));

If you are asking for T-SQL then lets look at fundamentals first. There are three types of joins here each with its own set of logical processing phases as:

1. A cross join is simplest of all. It implements only one logical query processing phase, a Cartesian Product. This phase operates on the two tables provided as inputs to the join and produces a Cartesian product of the two. That is, each row from one input is matched with all rows from the other. So if you have m rows in one table and n rows in the other, you get m×n rows in the result.
2. Then are Inner joins : They apply two logical query processing phases: A Cartesian product between the two input tables as in a cross join, and then it filters rows based on a predicate that you specify in ON clause (also known as Join condition).

3. Next comes the third type of joins, Outer Joins:

   In an outer join, you mark a table as a preserved table by using the keywords LEFT OUTER JOIN, RIGHT OUTER JOIN, or FULL OUTER JOIN between the table names. The OUTER keyword is optional. The LEFT keyword means that the rows of the left table are preserved; the RIGHT keyword means that the rows in the right table are preserved; and the FULL keyword means that the rows in both the left and right tables are preserved.

   The third logical query processing phase of an outer join identifies the rows from the preserved table that did not find matches in the other table based on the ON predicate. This phase adds those rows to the result table produced by the first two phases of the join, and uses NULL marks as placeholders for the attributes from the nonpreserved side of the join in those outer rows.

Now if we look at the question: To return records from the left table which are not found in the right table use Left outer join and filter out the rows with NULL values for the attributes from the right side of the join.

What you want is a Bag - which is like a set but also counts the number of occurances. Unfortunately the java Collections framework - great as they are dont have a Bag impl. For that one must use the Apache Common Collection link text

SELECT alarm_id
,definition_description
,element_id
,TO_CHAR (alarm_datetime, 'YYYY-MM-DD HH24:MI:SS')
,severity
, problem_text
,status 
FROM aircom.alarms 
WHERE status = 1 
    AND TO_char (alarm_datetime,'DD.MM.YYYY HH24:MI:SS') > TO_DATE ('07.09.2008  09:43:00', 'DD.MM.YYYY HH24:MI:SS') 
ORDER BY ALARM_DATETIME DESC 

There are two ways to do the redirect. Both apply to either subprocess.Popen or subprocess.call.

1. Set the keyword argument shell = True or executable = /path/to/the/shell and specify the command just as you have it there.

2. Since you're just redirecting the output to a file, set the keyword argument

   stdout = an_open_writeable_file_object
   

   where the object points to the output file.

subprocess.Popen is more general than subprocess.call.

Popen doesn't block, allowing you to interact with the process while it's running, or continue with other things in your Python program. The call to Popen returns a Popen object.

call does block. While it supports all the same arguments as the Popen constructor, so you can still set the process' output, environmental variables, etc., your script waits for the program to complete, and call returns a code representing the process' exit status.

returncode = call(*args, **kwargs) 

is basically the same as calling

returncode = Popen(*args, **kwargs).wait()

call is just a convenience function. It's implementation in CPython is in subprocess.py:

def call(*popenargs, timeout=None, **kwargs):
    """Run command with arguments.  Wait for command to complete or
    timeout, then return the returncode attribute.

    The arguments are the same as for the Popen constructor.  Example:

    retcode = call(["ls", "-l"])
    """
    with Popen(*popenargs, **kwargs) as p:
        try:
            return p.wait(timeout=timeout)
        except:
            p.kill()
            p.wait()
            raise

As you can see, it's a thin wrapper around Popen.

Functions in the exec() family have different behaviours:

• l : arguments are passed as a list of strings to the main()
• v : arguments are passed as an array of strings to the main()
• p : path/s to search for the new running program
• e : the environment can be specified by the caller

You can mix them, therefore you have:

• int execl(const char *path, const char *arg, ...);
• int execlp(const char *file, const char *arg, ...);
• int execle(const char *path, const char *arg, ..., char * const envp[]);
• int execv(const char *path, char *const argv[]);
• int execvp(const char *file, char *const argv[]);
• int execvpe(const char *file, char *const argv[], char *const envp[]);

For all of them the initial argument is the name of a file that is to be executed.

For more information read exec(3) man page:

man 3 exec  # if you are running a UNIX system

fout=open("out.csv","a")
for num in range(1,201):
    for line in open("sh"+str(num)+".csv"):
         fout.write(line)    
fout.close()

Need to make sure once switched into a frame, need to switch back to default content for accessing webelements in another frames. As Webdriver tend to find the new frame inside the current frame.

driver.switchTo().defaultContent()

Often you need some data for an example, however, you don't want to post your exact data. To use some existing data.frame in established library, use data command to import it.

e.g.,

data(mtcars)

and then do the problem

names(mtcars)
your problem demostrated on the mtcars data set

Starting in Django 1.2 RC1, if you're using the Django admin date picker widge trick, the following has to be added to your template, or you'll see the calendar icon url being referenced through "/missing-admin-media-prefix/".

{% load adminmedia %} /* At the top of the template. */

/* In the head section of the template. */
<script type="text/javascript">
window.__admin_media_prefix__ = "{% filter escapejs %}{% admin_media_prefix %}{% endfilter %}";
</script>

In C++11, use std::to_string if you can accept the default format (%f).

storedCorrect[count]= "(" + std::to_string(c1) + ", " + std::to_string(c2) + ")";

The following approach will sort the list in descending order and also handles the 'null' values, just in case if you have any null values then Collections.sort() will throw NullPointerException

      Collections.sort(list, new Comparator<Long>() {
          public int compare(Long o1, Long o2) {
                  return o1==null?Integer.MAX_VALUE:o2==null?Integer.MIN_VALUE:o2.compareTo(o1);

        }
    });

Directives are not "inside the angular world" as they say. So you have to use apply to get back into it when changing stuff

After some trial and error I came to this solution:

function center(img) {
    var div = img.parentNode;
    var divW = parseInt(div.style.width);
    var divH = parseInt(div.style.height);
    var srcW = img.width;
    var srcH = img.height;
    var ratio = Math.min(divW/srcW, divH/srcH);
    var newW = img.width * ratio;
    var newH = img.height * ratio;
    img.style.width  = newW + "px";
    img.style.height = newH + "px";
    img.style.marginTop = (divH-newH)/2 + "px";
    img.style.marginLeft = (divW-newW)/2 + "px";
}

PHP's getimagesize() returns an array of data. The first two items in the array are the two items you're interested in: the width and height. To get these, you would simply request the first two indexes in the returned array:

var $imagedata = getimagesize("someimage.jpg");

print "Image width  is: " . $imagedata[0];
print "Image height is: " . $imagedata[1];

For further information, see the documentation.

I know this has been answered to death already... but... no one has mentioned the javascript implementation of linq. Then the .distinct() method can be used - and it makes the code super easy to read.

var Linq = require('linq-es2015');
var distinctValues =  Linq.asEnumerable(testValues)
            .Select(x)
            .distinct()
            .toArray();

var testValues = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 1];_x000D_
_x000D_
var distinctValues = Enumerable.asEnumerable(testValues)_x000D_
  .distinct()_x000D_
  .toArray();_x000D_
_x000D_
console.log(distinctValues);

<script src="https://npmcdn.com/linq-es5/dist/linq.js"></script>

I have just been in a similar position with regards to setting the 777 permissions on the apache website hosting directory. After a little bit of tinkering it seems that changing the group ownership of the folder to the "apache" group allowed access to the folder based on the user group.

1) make sure that the group ownership of the folder is set to the group apache used / generates for use. (check /etc/groups, mine was www-data on Ubuntu)

2) set the folder permissions to 774 to stop "everyone" from having any change access, but allowing the owner and group permissions required.

3) add your user account to the group that has permission on the folder (mine was www-data).

I like to use the syntax '1 MonthName 2015' for dates ex:

   WHERE aa.AuditDate>='1 September 2015'
     AND aa.AuditDate<='30 September 2015'

for dates

This should get you for starting with two letters and ending with two numbers.

[A-Za-z]{2}(.*)[0-9]{2}

If you know it will always be just two and two you can

[A-Za-z]{2}[0-9]{2}

As you showed convincingly, the font-size: 100%; will not render the same in all browsers. However, you will set your font face in your CSS file, so this will be the same (or a fallback) in all browsers.

I believe font-size: 100%; can be very useful when combining it with em-based design. As this article shows, this will create a very flexible website.

When is this useful? When your site needs to adapt to the visitors' wishes. Take for example an elderly man that puts his default font-size at 24 px. Or someone with a small screen with a large resolution that increases his default font-size because he otherwise has to squint. Most sites would break, but em-based sites are able to cope with these situations.

You cannot insert a class into a vector, you can insert an object (provided that it is of the proper type or convertible) of a class though.

If the type Player has a default constructor, you can create a temporary object by doing Player(), and that should work for your case:

vectorOfGamers.push_back(Player());

Specifically...

How and where is app.run() used? After module definition or after app.config(), after app.controller()?

Where:

In your package.js E.g. /packages/dashboard/public/controllers/dashboard.js

How:

Make it look like this

var app = angular.module('mean.dashboard', ['ui.bootstrap']);

app.controller('DashboardController', ['$scope', 'Global', 'Dashboard',
    function($scope, Global, Dashboard) {
        $scope.global = Global;
        $scope.package = {
            name: 'dashboard'
        };
        // ...
    }
]);

app.run(function(editableOptions) {
    editableOptions.theme = 'bs3'; // bootstrap3 theme. Can be also 'bs2', 'default'
});

A height of 100% for is, presumably, the height of your browser's inner window, because that is the height of its parent, the page. An auto height will be the minimum height of necessary to contain .

even this will work:

<div class="container">
            <div class="row">
                <div class="col-4 col-sm-4 col-md-6 order-1">
                    1
                </div>
                <div class="col-4 col-sm-4  col-md-6 order-3">
                    2
                </div>
                <div class="col-4 col-sm-4  col-md-12 order-2">
                    3
                </div>
            </div>
          </div>

If you are using C++ 17 you can just use the inline specifier (see https://stackoverflow.com/a/11711082/55721)

If using older versions of the C++ standard, you must add the definitions to match your declarations of X and Y

unsigned char test::X;
unsigned char test::Y;

somewhere. You might want to also initialize a static member

unsigned char test::X = 4;

and again, you do that in the definition (usually in a CXX file) not in the declaration (which is often in a .H file)

Different versions of react between my shared libraries seemed to be the problem (16 and 17), changed both to 16.

if you are using boolean variable to bind the radio button. please refer below sample code

<div ng-repeat="book in books"> 
<input type="radio" ng-checked="book.selected"  
ng-click="function($event)">                        
</div>

Looks like a bug in VS code's OmniSharp.

Solution for me was to execute command "Restart OmniSharp".

Just do: - ctr shift P - type "Restart OmniSharp" .. hit enter

This fixed it for me.

This is the best and simplest way to understand joins:

You can do this way, providing Json or Any other variable:

1) For exemple, in the controller, you can use Json.NET to provide Json to the ViewBag:

ViewBag.Number = 10;
ViewBag.FooObj = JsonConvert.SerializeObject(new Foo { Text = "Im a foo." });

2) In the View, put the script like this at the bottom of the page.

<script type="text/javascript">
    var number = parseInt(@ViewBag.Number); //Accessing the number from the ViewBag
    alert("Number is: " + number);
    var model = @Html.Raw(@ViewBag.FooObj); //Accessing the Json Object from ViewBag
    alert("Text is: " + model.Text);
</script> 

very simple

  <img onload="loaded(this, 'success')" onerror="error(this, 
 'error')"  src="someurl"  alt="" />

 function loaded(_this, status){
   console.log(_this, status)
  // do your work in load
 }
 function error(_this, status){
  console.log(_this, status)
  // do your work in error
  }

For Me I just wanted to see the error in my VBA application so in the function I created the below code..

Function Database_FileRpt

You are trying to join Person_Fear.PersonID onto Person_Fear.FearID - This doesn't really make sense. You probably want something like:

SELECT Persons.Name, Persons.SS, Fears.Fear FROM Persons
LEFT JOIN Person_Fear
    INNER JOIN Fears
    ON Person_Fear.FearID = Fears.FearID
ON Person_Fear.PersonID = Persons.PersonID

This joins Persons onto Fears via the intermediate table Person_Fear. Because the join between Persons and Person_Fear is a LEFT JOIN, you will get all Persons records.

Alternatively:

SELECT Persons.Name, Persons.SS, Fears.Fear FROM Persons
LEFT JOIN Person_Fear ON Person_Fear.PersonID = Persons.PersonID
LEFT JOIN Fears ON Person_Fear.FearID = Fears.FearID

<?php
namespace CMS;
class Model {
  const _class = __CLASS__;
}

echo Model::_class; // will return 'CMS\Model'

for older than PHP 5.5

with open("filename") as f:

    print(f.read()[::-1])

Setting PYTHONPATH can also help with this problem.

Here is how it can be done on Windows

set PYTHONPATH=.

Authentication is the process of ascertaining that somebody really is who they claim to be.

Authorization refers to rules that determine who is allowed to do what. E.g. Adam may be authorized to create and delete databases, while Usama is only authorised to read.

The two concepts are completely orthogonal and independent, but both are central to security design, and the failure to get either one correct opens up the avenue to compromise.

In terms of web apps, very crudely speaking, authentication is when you check login credentials to see if you recognize a user as logged in, and authorization is when you look up in your access control whether you allow the user to view, edit, delete or create content.

There's not much of one in everyday work.

However, according to the documentation for both functions (accessed by putting a ? before the function name and hitting enter), require is used inside functions, as it outputs a warning and continues if the package is not found, whereas library will throw an error.

From the menu:

Build|Generate Signed APK

or

Build|Build APK

(the latter if you don't need a signed one to publish to the Play Store)

You could try the same address with HTTP instead of HTTPS. Be aware that this does use HTTP instead of HTTPS and only some sites might support this method.

Example address: https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

wget http://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

*notice the http:// instead of https://.

This is probably not recommended though :)

If you can, try use curl.

EDIT:

FYI an example with username (and prompt for password) would be:

curl --user $USERNAME -O http://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

Where -O is

 -O, --remote-name
              Write output to a local file named like the remote file we get. (Only the file part of the remote file is used, the path is cut off.)

You can do it either in XML or programmatically:

In XML:

card_view:cardBackgroundColor="@android:color/red"

Programmatically:

cardView.setCardBackgroundColor(Color.RED);

I like the code from @user2999943. But just some minor changes for my own purposes.

@Override
public boolean onTouchEvent(MotionEvent event)
{     
    switch(event.getAction())
    {
      case MotionEvent.ACTION_DOWN:
          x1 = event.getX();                         
      break;         
      case MotionEvent.ACTION_UP:
          x2 = event.getX();
          float deltaX = x2 - x1;

          if (Math.abs(deltaX) > MIN_DISTANCE)
          {
              // Left to Right swipe action
              if (x2 > x1)
              {
                  Toast.makeText(this, "Left to Right swipe [Next]", Toast.LENGTH_SHORT).show ();                     
              }

              // Right to left swipe action               
              else 
              {
                  Toast.makeText(this, "Right to Left swipe [Previous]", Toast.LENGTH_SHORT).show ();                    
              }

          }
          else
          {
              // consider as something else - a screen tap for example
          }                          
      break;   
    }           
    return super.onTouchEvent(event);       
}

I combined two solutions and it works fine for me.

window.addEventListener("orientationchange", function() {                   
    if (window.matchMedia("(orientation: portrait)").matches) {
       alert("PORTRAIT")
     }
    if (window.matchMedia("(orientation: landscape)").matches) {
      alert("LANSCAPE")
     }
}, false);

I don't know, it works fine for me. Exact commands:

import scipy, pylab
ax = pylab.subplot(111)
ax.scatter(scipy.randn(100), scipy.randn(100), c='b')
ax.scatter(scipy.randn(100), scipy.randn(100), c='r')
ax.figure.show()

Never hardcode this location. Use the environment variables %ProgramFiles% or %ProgramFiles(x86)%.

When specifying these, always quote because Microsoft may have put spaces or other special characters in them.

"%ProgramFiles%\theapp\app.exe"
"%ProgramFiles(x86)%\theapp\app.exe"

In addition, the directory might be expressed in a language you do not know. http://www.samlogic.net/articles/program-files-folder-different-languages.htm

>set|findstr /i /r ".*program.*="
CommonProgramFiles=C:\Program Files\Common Files
CommonProgramFiles(x86)=C:\Program Files (x86)\Common Files
CommonProgramW6432=C:\Program Files\Common Files
ProgramData=C:\ProgramData
ProgramFiles=C:\Program Files
ProgramFiles(x86)=C:\Program Files (x86)
ProgramW6432=C:\Program Files

Use these commands to find the values on a machine. DO NOT hardcode them into a program or .bat or .cmd file script. Use the variable.

set | findstr /R "^Program"
set | findstr /R "^Common"

For my case, I initially tried with

git config --system --unset credential.helper

But I was getting error

error: could not lock config file C:/Program Files/Git/etc/gitconfig: Permission denied

Then tried with

git config --global --unset credential.helper

No error, but still got access denied error while git pulling.

Then went to Control Panel -> Credentials Manager > Windows Credential and deleted git account.

After that when I tried git pull again, it asked for the credentials and a new git account added in Credentails manager.

FYI, for the cases where your page is loading with other javascript libraries like mootools that are conflicting with the $ symbol, you can use jQuery instead.

For instance, jQuery.fn.jquery or jQuery().jquery would work just fine:

Easiest way is probably to convert from a VARCHAR to a DATE; then format it back to a VARCHAR again in the format you want;

SELECT TO_CHAR(TO_DATE(DOJ,'MM/DD/YYYY'), 'MM/DD/YYYY') FROM EmpTable;

An SQLfiddle to test with.

A solution that works with all possible line endings including mixed ones and keeping empty lines as well can be achieved using two replaces and one split as follows

text.replace(/\r\n/g, "\r").replace(/\n/g, "\r").split(/\r/);

some code to test it

  var CR = "\x0D";  //   \r
  var LF = "\x0A";  //   \n

  var mixedfile = "00" + CR + LF +            // 1 x win
                  "01" + LF +                 // 1 x linux
                  "02" + CR +                 // 1 x old mac
                  "03" + CR + CR +            // 2 x old mac
                  "05" + LF + LF +            // 2 x linux
                  "07" + CR + LF + CR + LF +  // 2 x win
                  "09";

  function showarr (desc, arr)
  {
     console.log ("// ----- " + desc);
     for (var ii in arr)
        console.log (ii + ") [" + arr[ii] +  "] (len = " + arr[ii].length + ")");
  }

  showarr ("using 2 replace + 1 split", 
           mixedfile.replace(/\r\n/g, "\r").replace(/\n/g, "\r").split(/\r/));

and the output

  // ----- using 2 replace + 1 split
  0) [00] (len = 2)
  1) [01] (len = 2)
  2) [02] (len = 2)
  3) [03] (len = 2)
  4) [] (len = 0)
  5) [05] (len = 2)
  6) [] (len = 0)
  7) [07] (len = 2)
  8) [] (len = 0)
  9) [09] (len = 2)

Maybe try this? It seems the problem is solved after remove all the handlers in my case.

for handler in logging.root.handlers[:]:
    logging.root.removeHandler(handler)

logging.basicConfig(filename='output.log', level=logging.INFO)

It's important not to confuse the C# switch statement with the CIL switch instruction.

The CIL switch is a jump table, that requires an index into a set of jump addresses.

This is only useful if the C# switch's cases are adjacent:

case 3: blah; break;
case 4: blah; break;
case 5: blah; break;

But of little use if they aren't:

case 10: blah; break;
case 200: blah; break;
case 3000: blah; break;

(You'd need a table ~3000 entries in size, with only 3 slots used)

With non-adjacent expressions, the compiler may start to perform linear if-else-if-else checks.

With larger non- adjacent expression sets, the compiler may start with a binary tree search, and finally if-else-if-else the last few items.

With expression sets containing clumps of adjacent items, the compiler may binary tree search, and finally a CIL switch.

This is full of "mays" & "mights", and it is dependent on the compiler (may differ with Mono or Rotor).

I replicated your results on my machine using adjacent cases:

total time to execute a 10 way switch, 10000 iterations (ms) : 25.1383
approximate time per 10 way switch (ms) : 0.00251383

total time to execute a 50 way switch, 10000 iterations (ms) : 26.593
approximate time per 50 way switch (ms) : 0.0026593

total time to execute a 5000 way switch, 10000 iterations (ms) : 23.7094
approximate time per 5000 way switch (ms) : 0.00237094

total time to execute a 50000 way switch, 10000 iterations (ms) : 20.0933
approximate time per 50000 way switch (ms) : 0.00200933

Then I also did using non-adjacent case expressions:

total time to execute a 10 way switch, 10000 iterations (ms) : 19.6189
approximate time per 10 way switch (ms) : 0.00196189

total time to execute a 500 way switch, 10000 iterations (ms) : 19.1664
approximate time per 500 way switch (ms) : 0.00191664

total time to execute a 5000 way switch, 10000 iterations (ms) : 19.5871
approximate time per 5000 way switch (ms) : 0.00195871

A non-adjacent 50,000 case switch statement would not compile.
"An expression is too long or complex to compile near 'ConsoleApplication1.Program.Main(string[])'

What's funny here, is that the binary tree search appears a little (probably not statistically) quicker than the CIL switch instruction.

Brian, you've used the word "constant", which has a very definite meaning from a computational complexity theory perspective. While the simplistic adjacent integer example may produce CIL that is considered O(1) (constant), a sparse example is O(log n) (logarithmic), clustered examples lie somewhere in between, and small examples are O(n) (linear).

This doesn't even address the String situation, in which a static Generic.Dictionary<string,int32> may be created, and will suffer definite overhead on first use. Performance here will be dependent on the performance of Generic.Dictionary.

If you check the C# Language Specification (not the CIL spec) you'll find "15.7.2 The switch statement" makes no mention of "constant time" or that the underlying implementation even uses the CIL switch instruction (be very careful of assuming such things).

At the end of the day, a C# switch against an integer expression on a modern system is a sub-microsecond operation, and not normally worth worrying about.

Of course these times will depend on machines and conditions. I wouldn’t pay attention to these timing tests, the microsecond durations we’re talking about are dwarfed by any “real” code being run (and you must include some “real code” otherwise the compiler will optimise the branch away), or jitter in the system. My answers are based on using IL DASM to examine the CIL created by the C# compiler. Of course, this isn’t final, as the actual instructions the CPU runs are then created by the JIT.

I have checked the final CPU instructions actually executed on my x86 machine, and can confirm a simple adjacent set switch doing something like:

  jmp     ds:300025F0[eax*4]

Where a binary tree search is full of:

  cmp     ebx, 79Eh
  jg      3000352B
  cmp     ebx, 654h
  jg      300032BB
  …
  cmp     ebx, 0F82h
  jz      30005EEE

Alternatively to add downloaded box, a json file with metadata can be created. This way some additional details can be applied. For example to import box and specifying its version create file:

{
  "name": "laravel/homestead",
  "versions": [
    {
      "version": "7.0.0",
      "providers": [
        {
          "name": "virtualbox",
          "url": "file:///path/to/box/virtualbox.box"
        }
      ]
    }
  ]
}

Then run vagrant box add command with parameter:

vagrant box add laravel/homestead /path/to/metadata.json

You can try to set_time_limit(n). However, if your PHP setup is running in safe mode, you can only change it from the php.ini file.

The CPU can only understand machine code indeed. For interpreted programs, the ultimate goal of an interpreter is to "interpret" the program code into machine code. However, usually a modern interpreted language does not interpret human code directly because it is too inefficient.

The Python interpreter first reads the human code and optimizes it to some intermediate code before interpreting it into machine code. That's why you always need another program to run a Python script, unlike in C++ where you can run the compiled executable of your code directly. For example, c:\Python27\python.exe or /usr/bin/python.

I found the error: I have a library that it was built using jdk 1.6. The Spring main controller and components are in this library. And how I use jdk 1.7, It does not find the classes built in 1.6.

The solution was built all using "compiler compliance level: 1.7" and "Generated .class files compatibility: 1.6", "Source compatibility: 1.6".

I setup this option in Eclipse: Preferences\Java\Compiler.

Thanks everybody.

You can't revert a md5 password.(in any language)

But you can:

give to the user a new one.

check in some rainbow table to maybe retrieve the old one.

$table->date('user_id')->nullable();

In your file create_file, the null option must be enabled.

In case you want send your custom headers, you can do it this way:

curl -v -H @{'custom_header'='custom_header_value'} http://localhost:3000/action?result1=gh&result2=ghk

Another option that's pretty clean (No pun intended.):

git clean -ndX

Explanation:

$ git help clean

git-clean - Remove untracked files from the working tree
-n, --dry-run - Don't actually remove anything, just show what would be done.
-d - Remove untracked directories in addition to untracked files.
-X - Remove only files ignored by Git.

Note: This solution will not show ignored files that have already been removed.

I needed to rotate a 3D model around one of the three axes {x, y, z} in which that model was embedded and this was the top result for a search of how to do this in numpy. I used the following simple function:

def rotate(X, theta, axis='x'):
  '''Rotate multidimensional array `X` `theta` degrees around axis `axis`'''
  c, s = np.cos(theta), np.sin(theta)
  if axis == 'x': return np.dot(X, np.array([
    [1.,  0,  0],
    [0 ,  c, -s],
    [0 ,  s,  c]
  ]))
  elif axis == 'y': return np.dot(X, np.array([
    [c,  0,  -s],
    [0,  1,   0],
    [s,  0,   c]
  ]))
  elif axis == 'z': return np.dot(X, np.array([
    [c, -s,  0 ],
    [s,  c,  0 ],
    [0,  0,  1.],
  ]))

You need to identify the primary key in TableA in order to delete the correct record. The primary key may be a single column or a combination of several columns that uniquely identifies a row in the table. If there is no primary key, then the ROWID pseudo column may be used as the primary key.

DELETE FROM tableA
WHERE ROWID IN 
  ( SELECT q.ROWID
    FROM tableA q
      INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum) 
    WHERE (LENGTH(q.memotext) NOT IN (8,9,10) OR q.memotext NOT LIKE '%/%/%')
      AND (u.FldFormat = 'Date'));

Implement __str__() or __repr__() in the class's metaclass.

class MC(type):
  def __repr__(self):
    return 'Wahaha!'

class C(object):
  __metaclass__ = MC

print C

Use __str__ if you mean a readable stringification, use __repr__ for unambiguous representations.

To get size of viewport on load and on resize (based on SimaWB response):

function getViewport() {
    var viewportWidth = $(window).width();
    var viewportHeight = $(window).height();
    $('#viewport').html('Viewport: '+viewportWidth+' x '+viewportHeight+' px');
}

getViewport();

$(window).resize(function() {
    getViewport()
});

Short answer

"The irony of JDBC is that, although the programming interfaces are portable, the SQL language is not. Despite the many attempts to standardize it, it is still rare to write SQL of any complexity that will run unchanged on two major database platforms. Even where the SQL dialects are similar, each database performs differently depending on the structure of the query, necessitating vendor-specific tuning in most cases."

..stolen from Pro JPA 2 Mastering the Java Persistence API, chapter 1, page 9

So, we might think of JDBC as the ultimate specification that abstracts away everything related to databases, but it isn't.

A quote from the JDBC specification, chapter 4.4, page 20:

The driver layer may mask differences between standard SQL:2003 syntax and the native dialect supported by the data source.

May is no guarantee that the driver will, and therefore we should provide the dialect in order to have a working application. In a best-case scenario, the application will work but might not run as effectively as it could if the persistence provider knew which dialect to use. In the case of Hibernate he will refuse to deploy your application unless you feed him the dialect.

What about JPQL then?

The JDBC specification does not mention the word JPQL. JDBC is a standardized way of database access. Go read this JavaDoc and you will find that once the application can access the database, what must be fed into the JDBC compliant driver is vanilla ^{= undecorated} SQL.

It is worth noting that JPQL is a query language, not a data definition language (DDL). So even if we could feed the JDBC driver with JPQL, that would be of no use for the persistence provider during the phase of parsing the persistence.xml file and setting up tables.

Closer look at the property

For your reference, here is an example for Hibernate and EclipseLink on how to specify a Java DB dialect in the persistence.xml file:

<property name="hibernate.dialect" value="org.hibernate.dialect.DerbyTenSevenDialect"/>
<property name="eclipselink.target-database" value="JavaDB"/>

Is the property mandatory?

In theory, the property has not been standardized and the JPA 2.1 specification says not a word about SQL dialects. So we're out of luck and must turn to vendor specific empirical studies and documentation thereof.

Hibernate refuse to accept a deployment archive that hasn't specified the property rendering the archive undeployable. Hibernate documentation says:

Always set the hibernate.dialect property to the correct org.hibernate.dialect.Dialect subclass for your database.

So that is pretty clear. Do note that the dialects listed in the documentation are specifically targeting one or the other vendor. There is no "generic" dialect or anything like that. Given then that the property is an absolute requirement for a successful deployment, you would expect that the documentation of the WildFly application server which bundles Hibernate should say something, but it doesn't.

EclipseLink on the other hand is a bit more forgiving. If you don't provide the property, the deployment deploys (without warning too). EclipseLink documentation says:

Use the eclipselink.target-database property to specify the database to use, controlling custom operations and SQL generation for the specified database.

The talk is about "custom operations and SQL generation", meaning it is bit vague if you ask me. But one thing is clear: They don't say that the property is mandatory. Also note that one of the available values is "Database" which represent "a generic database" target. Hmm, what "dialect" would that be? SQL 2.0?? But then again, the property is called "target-database" and not "dialect" so maybe "Database" translates to no SQL at all lol. Moving on to the GlassFish server which bundles EclipseLink. Documentation (page "6-3") says:

You can specify the optional eclipselink.target-database property to guarantee that the database type is correct.

So GlassFish argues that the property is "optional" and the value added is a "guarantee" that I am actually using Java DB - in case I didn't know.

Conclusion

Copy-paste whatever you can find on google and pray to God.

After my initial struggle with the link and controller functions and reading quite a lot about them, I think now I have the answer.

First lets understand,

How do angular directives work in a nutshell:

• We begin with a template (as a string or loaded to a string)

  var templateString = '<div my-directive>{{5 + 10}}</div>';

• Now, this templateString is wrapped as an angular element

  var el = angular.element(templateString);

• With el, now we compile it with $compile to get back the link function.

  var l = $compile(el)

  Here is what happens,

  • $compile walks through the whole template and collects all the directives that it recognizes.
  • All the directives that are discovered are compiled recursively and their link functions are collected.
  • Then, all the link functions are wrapped in a new link function and returned as l.

• Finally, we provide scope function to this l (link) function which further executes the wrapped link functions with this scope and their corresponding elements.

  l(scope)

• This adds the template as a new node to the DOM and invokes controller which adds its watches to the scope which is shared with the template in DOM.

Comparing compile vs link vs controller :

• Every directive is compiled only once and link function is retained for re-use. Therefore, if there's something applicable to all instances of a directive should be performed inside directive's compile function.

• Now, after compilation we have link function which is executed while attaching the template to the DOM. So, therefore we perform everything that is specific to every instance of the directive. For eg: attaching events, mutating the template based on scope, etc.

• Finally, the controller is meant to be available to be live and reactive while the directive works on the DOM (after getting attached). Therefore:

  (1) After setting up the view[V] (i.e. template) with link. $scope is our [M] and $controller is our [C] in M V C

  (2) Take advantage the 2-way binding with $scope by setting up watches.

  (3) $scope watches are expected to be added in the controller since this is what is watching the template during run-time.

  (4) Finally, controller is also used to be able to communicate among related directives. (Like myTabs example in https://docs.angularjs.org/guide/directive)

  (5) It's true that we could've done all this in the link function as well but its about separation of concerns.

Therefore, finally we have the following which fits all the pieces perfectly :

If you are using prototype.js then you can do this:

transport_select.observe('change', function(){
  toggleSelect(transport_select_id)
})

This eliminate (as hope) the problem in cross-browsers

if exist C:\VTS\NUL echo "Folder already exists"

if not exist C:\VTS\NUL echo "Folder does not exist"

I use (a very old) process explorer from SysInternals (procexp.exe). It is a replacement / addition to the standard Task manager, you can suspend a process from there.

Edit: Microsoft has bought over SysInternals, url: procExp.exe

Other than that you can set the process priority to low so that it does not get in the way of other processes, but this will not suspend the process.

Thanks for this very useful script. I had some tiny problems running it on old systems (Red Hat Enterprise 3, which handle differently egrep and tabs in strings), and other systems with nothing in /etc/cron.d/ (the script then ended with an error). So here is a patch to make it work in such cases :

I'm not really sure the changes in the first egrep are a good idea, but well, this script has been tested on RHEL3,4,5 and Debian5 without any problem. Hope this helps!

You have 2 ways of doing it:

• You can create a table (or multiple tables linked together) with a field for each key of your array, and insert into each field the corresponding value of your array. This is the most common way
• You can just have a table with one field and put in here your array serialized. I do not recommend you do do that, but it is useful if you don't want a complex database schema.

In simplest words :P If it is safe to execute multiple threads on a block of code it is thread safe*

*conditions apply

Conditions are mentioned by other answeres like 1. The result should be same if you execute one thread or multiple threads over it etc.

For OSX:

I had installed this via Anaconda, and had a hell of a time getting it to work. What helped was adding the Anaconda bin AND pkgs folder to my PATH.

Since I use fishshell, I did it in my ~/.config/fish/config.fish file like this:

set -g -x PATH $PATH /Users/cbrevik/anaconda/bin /Users/cbrevik/anaconda/pkgs

If you use fishshell like me, this answer will probably save you some trouble later using pandas as well.

Usually a null pointer (which can be of any type, including a void pointer !) points to:

• the address 0, against which most CPU instructions sets can do a very fast compare-and-branch (to check for uninitialized or invalid pointers, for instance) with optimal code size/performance for the ISA.

• an address that's illegal for user code to access (such as 0x00000000 in many cases), so that if a code actually tries to access data at or near this address, the OS or debugger can easily stop or trap a program with this bug.

A void pointer is usually a method of cheating or turning-off compiler type checking, for instance if you want to return a pointer to one type, or an unknown type, to use as another type. For instance malloc() returns a void pointer to a type-less chunk of memory, the type of which you can cast to later use as a pointer to bytes, short ints, double floats, typePotato's, or whatever.

Your string may contain non Latin1 characters, which leads to undefined data. It depends of what you mean by "it deosn't seem to work".

on ubuntu 18.04 ( virtualenv, python.3.6.x), the following reload snippet solved the problem for me:

main.py

import my_module  # my_module.py
from importlib import reload # reload 
reload(my_module)

print(my_module)
print(my_modeule.hello())

where:

|--main.py    
|--my_module.py

I think I got the reason for the above error. It is the corporate proxy(virtual private network) provided in order to work in the client network. Without that connection I frequently faced the same problem be it maven build or npm install.

If you want to see the environment variable you just set, you need to open a new command window.

Variables set with setx variables are available in future command windows only, not in the current command window. (Setx, Examples)

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

Here is the same solution (with some extra bonus code) in just one XML file:

You then just set the background attribute to edittext_rounded_corners.xml file:

<EditText  android:id="@+id/editText_name"
      android:background="@drawable/edittext_rounded_corners"/>

While I haven't found a good way to specify proxy network credentials in the web.config, you might find that you can still use a non-coding solution, by including this in your web.config:

  <system.net>
    <defaultProxy useDefaultCredentials="true">
      <proxy proxyaddress="proxyAddress" usesystemdefault="True"/>
    </defaultProxy>
  </system.net>

The key ingredient in getting this going, is to change the IIS settings, ensuring the account that runs the process has access to the proxy server. If your process is running under LocalService, or NetworkService, then this probably won't work. Chances are, you'll want a domain account.

I recommend http://stacktrace.sourceforge.net/ project. It support Windows, Mac OS and also Linux

Although BETWEEN is easy to read and maintain, I rarely recommend its use because it is a closed interval and as mentioned previously this can be a problem with dates - even without time components.

For example, when dealing with monthly data it is often common to compare dates BETWEEN first AND last, but in practice this is usually easier to write dt >= first AND dt < next-first (which also solves the time part issue) - since determining last usually is one step longer than determining next-first (by subtracting a day).

In addition, another gotcha is that lower and upper bounds do need to be specified in the correct order (i.e. BETWEEN low AND high).

For what it is worth, most scripting languages (like Perl) and non-static compile-time languages (like Pick) support automatic run-time dynamic String to (relatively arbitrary) object conversions. This CAN be accomplished in Java as well without losing type-safety and the good stuff statically-typed languages provide WITHOUT the nasty side-effects of some of the other languages that do evil things with dynamic casting. A Perl example that does some questionable math:

print ++($foo = '99');  # prints '100'
print ++($foo = 'a0');  # prints 'a1'

In Java, this is better accomplished (IMHO) by using a method I call "cross-casting". With cross-casting, reflection is used in a lazy-loaded cache of constructors and methods that are dynamically discovered via the following static method:

Object fromString (String value, Class targetClass)

Unfortunately, no built-in Java methods such as Class.cast() will do this for String to BigDecimal or String to Integer or any other conversion where there is no supporting class hierarchy. For my part, the point is to provide a fully dynamic way to achieve this - for which I don't think the prior reference is the right approach - having to code every conversion. Simply put, the implementation is just to cast-from-string if it is legal/possible.

So the solution is simple reflection looking for public Members of either:

STRING_CLASS_ARRAY = (new Class[] {String.class});

a) Member member = targetClass.getMethod(method.getName(),STRING_CLASS_ARRAY); b) Member member = targetClass.getConstructor(STRING_CLASS_ARRAY);

You will find that all of the primitives (Integer, Long, etc) and all of the basics (BigInteger, BigDecimal, etc) and even java.regex.Pattern are all covered via this approach. I have used this with significant success on production projects where there are a huge amount of arbitrary String value inputs where some more strict checking was needed. In this approach, if there is no method or when the method is invoked an exception is thrown (because it is an illegal value such as a non-numeric input to a BigDecimal or illegal RegEx for a Pattern), that provides the checking specific to the target class inherent logic.

There are some downsides to this:

1) You need to understand reflection well (this is a little complicated and not for novices). 2) Some of the Java classes and indeed 3rd-party libraries are (surprise) not coded properly. That is, there are methods that take a single string argument as input and return an instance of the target class but it isn't what you think... Consider the Integer class:

static Integer getInteger(String nm)
      Determines the integer value of the system property with the specified name.

The above method really has nothing to do with Integers as objects wrapping primitives ints. Reflection will find this as a possible candidate for creating an Integer from a String incorrectly versus the decode, valueof and constructor Members - which are all suitable for most arbitrary String conversions where you really don't have control over your input data but just want to know if it is possible an Integer.

To remedy the above, looking for methods that throw Exceptions is a good start because invalid input values that create instances of such objects should throw an Exception. Unfortunately, implementations vary as to whether the Exceptions are declared as checked or not. Integer.valueOf(String) throws a checked NumberFormatException for example, but Pattern.compile() exceptions are not found during reflection lookups. Again, not a failing of this dynamic "cross-casting" approach I think so much as a very non-standard implementation for exception declarations in object creation methods.

If anyone would like more details on how the above was implemented, let me know but I think this solution is much more flexible/extensible and with less code without losing the good parts of type-safety. Of course it is always best to "know thy data" but as many of us find, we are sometimes only recipients of unmanaged content and have to do the best we can to use it properly.

Cheers.

Alternative way with substring and regexpr:

substring(name, 1) <- toupper(substring(name, 1, 1))
pos <- regexpr(" ", name, perl=TRUE) + 1
substring(name, pos) <- toupper(substring(name, pos, pos))

Use \D to match non-digit characters.

preg_replace('~\D~', '', $str);

Yup, I have found the solution for dis issue.

• Create one slider box with extra width from both side( Which we can use to add item space from both sides ).
• Create Inner Item Content with proper width & margin from both sides( This should be your actual wrapper size )
• Done

You must "build" before "run", otherwise "Binary not found". You can set up "Auto build", so that it will build and run. Check this post to set up "Auto build" http://situee.blogspot.com/2012/08/how-to-set-eclipse-cdt-auto-build.html

You can simply do like this In Template

<span ng-cloak>{{amount |firstFiler:'firstArgument':'secondArgument' }}</span>

In filter

angular.module("app")
.filter("firstFiler",function(){

    console.log("filter loads");
    return function(items, firstArgument,secondArgument){
        console.log("item is ",items); // it is value upon which you have to filter
        console.log("firstArgument is ",firstArgument);
        console.log("secondArgument ",secondArgument);

        return "hello";
    }
    });

There is no difference between the two in how they are stored in memory and registers, there is no signed and unsigned version of int registers there is no signed info stored with the int, the difference only becomes relevant when you perform maths operations, there are signed and unsigned version of the maths ops built into the CPU and the signedness tell the compiler which version to use.

The answer below uses git log:

I mentioned a similar approach in 2009 with "Unable to show a Git tree in terminal":

git log --graph --pretty=oneline --abbrev-commit

But the full one I have been using is in "How to display the tag name and branch name using git log --graph" (2011):

git config --global alias.lgb "log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset%n' --abbrev-commit --date=relative --branches"

git lgb

Original answer (2010)

git show-branch --list comes close of what you are looking for (with the topo order)

--topo-order

By default, the branches and their commits are shown in reverse chronological order.
This option makes them appear in topological order (i.e., descendant commits are shown before their parents).

But the tool git wtf can help too. Example:

$ git wtf
Local branch: master
[ ] NOT in sync with remote (needs push)
    - Add before-search hook, for shortcuts for custom search queries. [4430d1b] (edwardzyang@...; 7 days ago)
Remote branch: origin/master ([email protected]:sup/mainline.git)
[x] in sync with local

Feature branches:
{ } origin/release-0.8.1 is NOT merged in (1 commit ahead)
    - bump to 0.8.1 [dab43fb] (wmorgan-sup@...; 2 days ago)
[ ] labels-before-subj is NOT merged in (1 commit ahead)
    - put labels before subject in thread index view [790b64d] (marka@...; 4 weeks ago)
{x} origin/enclosed-message-display-tweaks merged in
(x) experiment merged in (only locally)

NOTE: working directory contains modified files

git-wtf shows you:

• How your branch relates to the remote repo, if it's a tracking branch.
• How your branch relates to non-feature ("version") branches, if it's a feature branch.
• How your branch relates to the feature branches, if it's a version branch

Strings, by C definition, are terminated by '\0'. You have no "C strings" in your program.

Your program reads characters (buffered till ENTER) from the standard input (the keyboard) and writes them back to the standard output (the screen). It does this no matter how many characters you type or for how long you do this.

To stop the program you have to indicate that the standard input has no more data (huh?? how can a keyboard have no more data?).

You simply press Ctrl+D (Unix) or Ctrl+Z (Windows) to pretend the file has reached its end.
Ctrl+D (or Ctrl+Z) are not really characters in the C sense of the word.

If you run your program with input redirection, the EOF is the actual end of file, not a make belief one
./a.out < source.c

self.materials is a dict and by default you are iterating over just the keys (which are strings).

Since self.materials has more than two keys*, they can't be unpacked into the tuple "k, m", hence the ValueError exception is raised.

In Python 2.x, to iterate over the keys and the values (the tuple "k, m"), we use self.materials.iteritems().

However, since you're throwing the key away anyway, you may as well simply iterate over the dictionary's values:

for m in self.materials.itervalues():

In Python 3.x, prefer dict.values() (which returns a dictionary view object):

for m in self.materials.values():

If you have imagemagick installed, then you can put the following alias into your .bash_profile. It will convert every png in a directory to a jpg, which automatically removes the alpha. You can use the resulting jpg files as your screen shots.

alias pngToJpg='for i in *.png; do convert $i ${i/.png/}.jpg; done'

Apache FileUtil gives very handy methods to do the conversion

try {
    File file = new File(imagefilePath);
    byte[] byteArray = new byte[file.length()]();
    byteArray = FileUtils.readFileToByteArray(file);  
 }catch(Exception e){
     e.printStackTrace();

 }

I don't know about the performance statistics on this one, but have you tried using the Directory.GetFiles() static method ?

It returns a string array containing filenames (not FileInfos) and you can check the length of the array in the same way as above.

You have to change your HEAD, Not yours of course but git HEAD....

So before answering let's add some background, explaining what is this HEAD.

First of all what is HEAD?

HEAD is simply a reference to the current commit (latest) on the current branch.
There can only be a single HEAD at any given time. (excluding git worktree)

The content of HEAD is stored inside .git/HEAD and it contains the 40 bytes SHA-1 of the current commit.

detached HEAD

If you are not on the latest commit - meaning that HEAD is pointing to a prior commit in history its called detached HEAD.

On the command line, it will look like this- SHA-1 instead of the branch name since the HEAD is not pointing to the tip of the current branch

A few options on how to recover from a detached HEAD:

git checkout

git checkout <commit_id>
git checkout -b <new branch> <commit_id>
git checkout HEAD~X // x is the number of commits t go back

This will checkout new branch pointing to the desired commit.
This command will checkout to a given commit.
At this point, you can create a branch and start to work from this point on.

# Checkout a given commit. 
# Doing so will result in a `detached HEAD` which mean that the `HEAD`
# is not pointing to the latest so you will need to checkout branch
# in order to be able to update the code.
git checkout <commit-id>

# create a new branch forked to the given commit
git checkout -b <branch name>

git reflog

You can always use the reflog as well.
git reflog will display any change which updated the HEAD and checking out the desired reflog entry will set the HEAD back to this commit.

Every time the HEAD is modified there will be a new entry in the reflog

git reflog
git checkout HEAD@{...}

This will get you back to your desired commit

git reset --hard <commit_id>

"Move" your HEAD back to the desired commit.

# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32

# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts if you've modified things which were
# changed since the commit you reset to.

• Note: (Since Git 2.7)
  you can also use the git rebase --no-autostash as well.

git revert <sha-1>

"Undo" the given commit or commit range.
The reset command will "undo" any changes made in the given commit.
A new commit with the undo patch will be committed while the original commit will remain in the history as well.

# add new commit with the undo of the original one.
# the <sha-1> can be any commit(s) or commit range
git revert <sha-1>

This schema illustrates which command does what.
As you can see there reset && checkout modify the HEAD.

Not sure if it's just me, but using .remove() doesn't seem to work if you are selecting by an id.

Ex: $("#my-element").remove();

I had to use the element's class instead, or nothing happened.

Ex: $(".my-element").remove();

I found that you can put the .col class on the image will do the trick - however this gives it extra padding along with any other attributes associated with the class such as float left, however these can be cancelled by say for example a no padding class as an addition.

Why use raw SQL for this?

If you have a model for it use where:

f1 = 'foo'
f2 = 'bar'
f3 = 'buzz'
YourModel.where('f1 = ? and f2 = ?', f1, f2).each do |ym|
  # or where(f1: f1, f2: f2).each do (...)
  ym.update(f3: f3) 
end

If you don't have a model for it (just the table), you can create a file and model that will inherit from ActiveRecord::Base

class YourTable < ActiveRecord::Base
  self.table_name = 'your_table' # specify explicitly if needed
end

and again use where the same as above:

In current version of Jekyll, it defaults to http://127.0.0.1:4000/.
This is good, if you are connected to a network but do not want anyone else to access your application.

However it may happen that you want to see how your application runs on a mobile or from some other laptop/computer.

In that case, you can use

jekyll serve --host 0.0.0.0

This binds your application to the host & next use following to connect to it from some other host

http://host's IP adress/4000 

First select drive that is where Android sdk folder is there. Then you Follow the below steps

cd DriveName:/ or Ex : cd c:/ Press 'Enter'

then you will give the path that is adb console path is there in a platform-tools folder so cd Root Folder/inner root folder if there/Platform-tools Press 'Enter' then it selects the adb directory.

use simple code for remove default browser style for outline

input { outline: none; }

you can do it better with two datagridview, you add the same datasource , hide the headers of the second, set the height of the second = to the height of the rows of the first, turn off all resizable atributes of the second, synchronize the scrollbars of both, only horizontal, put the second on the botton of the first etc.

take a look:

   dgv3.ColumnHeadersVisible = false;
   dgv3.Height = dgv1.Rows[0].Height;
   dgv3.Location = new Point(Xdgvx, this.dgv1.Height - dgv3.Height - SystemInformation.HorizontalScrollBarHeight);
   dgv3.Width = dgv1.Width;

   private void dgv1_Scroll(object sender, ScrollEventArgs e)
        {
            if (e.ScrollOrientation == ScrollOrientation.HorizontalScroll)
            {
                dgv3.HorizontalScrollingOffset = e.NewValue;
            }
        }

If this is in fact a ListObject table (Insert Table from the ribbon) then you can use the table's .DataBodyRange object to get the number of rows and columns. This ignores the header row.

Sub TableTest()

Dim tbl As ListObject
Dim tRows As Long
Dim tCols As Long

Set tbl = ActiveSheet.ListObjects("Table1")  '## modify to your table name.

With tbl.DataBodyRange
    tRows = .Rows.Count
    tCols = .Columns.Count
End With

MsgBox tbl.Name & " contains " & tRows & " rows and " & tCols & " columns.", vbInformation

End Sub

If you need to use the header row, instead of using tbl.DataBodyRange just use tbl.Range.

You can use a javascript image processing framework for client-side image processing before uploading the image to the server.

Below I used MarvinJ to create a runnable code based on the example in the following page: "Processing images in client-side before uploading it to a server"

Actually there are some cases that above answers would break. Such as wrongly input value, wrongly input range, negative input/output ranges.

def remap( x, oMin, oMax, nMin, nMax ):

    #range check
    if oMin == oMax:
        print "Warning: Zero input range"
        return None

    if nMin == nMax:
        print "Warning: Zero output range"
        return None

    #check reversed input range
    reverseInput = False
    oldMin = min( oMin, oMax )
    oldMax = max( oMin, oMax )
    if not oldMin == oMin:
        reverseInput = True

    #check reversed output range
    reverseOutput = False   
    newMin = min( nMin, nMax )
    newMax = max( nMin, nMax )
    if not newMin == nMin :
        reverseOutput = True

    portion = (x-oldMin)*(newMax-newMin)/(oldMax-oldMin)
    if reverseInput:
        portion = (oldMax-x)*(newMax-newMin)/(oldMax-oldMin)

    result = portion + newMin
    if reverseOutput:
        result = newMax - portion

    return result

Cached loop should be fastest (at least when called multiple times)

var factorial = (function() {
  var x =[];

  return function (num) {
    if (x[num] >0) return x[num];
    var rval=1;
    for (var i = 2; i <= num; i++) {
        rval = rval * i;
        x[i] = rval;
    }
    return rval;
  }
})();

If using Visual Studio 2010 you can right-click on the project for the service, and select properties. Then select the Web tab. Under the Servers section you can configure the URL. There is also a button to create the virtual directory.

ClickOnce applications are stored under the user's profile at %LocalAppData%\Apps\2.0\.

From there, use the search function to find your application.

If you've just inserted a record into the Customers table and you need the value of the recently populated ID field, you can use the SCOPE_IDENTITY function. This is only useful when the INSERT has occurred within the same scope as the call to SCOPE_IDENTITY.

INSERT INTO Customers(ID, FirstName, LastName)
Values
(23, 'Bob', 'Smith')

SET @mostRecentId = SCOPE_IDENTITY()

This may or may not be useful for you, but it's a good technique to be aware of. It will also work with auto-generated columns.

Normalise the data then store as a varchar. Normalising could be tricky.

That should be a one-time hit. Then as a new record comes in, you're comparing it to normalised data. Should be very fast.

As of Angular 2.2.3 there is now a forwardRef() utility function that allows you to inject providers that have not yet been defined.

By not defined, I mean that the dependency injection map doesn't know the identifier. This is what happens during circular dependencies. You can have circular dependencies in Angular that are very difficult to untangle and see.

export class HeaderComponent {
  mobileNav: boolean = false;

  constructor(@Inject(forwardRef(() => MobileService)) public ms: MobileService) {
    console.log(ms);
  }

}

Adding @Inject(forwardRef(() => MobileService)) to the parameter of the constructor in the original question's source code will fix the problem.

Sometimes, PHP will emit a X-Powered-By: response header which you can look at e.g. using Firebug.

If this setting (controlled by the ini setting expose_php) is turned off (it often is), there is no way to tell the PHP version used - and rightly so. What PHP version is running is none of the outside world's business, and it's good to obscure this from a security perspective.

this is just and slice of code, hope works for you

You need to encode Unicode explicitly before writing to a file, otherwise Python does it for you with the default ASCII codec.

Pick an encoding and stick with it:

f.write(printinfo.encode('utf8') + '\n')

or use io.open() to create a file object that'll encode for you as you write to the file:

import io

f = io.open(filename, 'w', encoding='utf8')

The correct shorthand is this:

$(function() {
    // this behaves as if within document.ready
});

The code you posted…

(function($){

//some code

})(jQuery);

…creates an anonymous function and executes it immediately with jQuery being passed in as the arg $. All it effectively does is take the code inside the function and execute it like normal, since $ is already an alias for jQuery. :D

It's crucial for code obfuscation, like this:

Look->       See?!

No

Oh, well

Note that on OS X you might get strange errors like "invalid command code" or other strange errors when running this command. To fix this issue try

sed -i '' -e "s/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g" <file>

This is because on the OSX version of sed, the -i option expects an extension argument so your command is actually parsed as the extension argument and the file path is interpreted as the command code. Source: https://stackoverflow.com/a/19457213

Click on the Monitor (DDMS Included) button on the toolbar -- it looks like the Android bugdroid:

That will bring up the DDMS window. Select the emulator instance from the Devices tab on the left, and click on the camera button in the toolbar above it, next to the stop sign icon:

Note that if your emulator is running Android 4.4 or I think 4.3, then screen capture functionality is broken -- you'll have to use a physical device to get screenshots on those OS versions. It works okay for Android prior to 4.3. That bug is https://code.google.com/p/android/issues/detail?id=62284

From the man page:

-h, --no-filename
    Suppress the prefixing of file names on output. This is the default when there
    is only one file (or only standard input) to search.

document.getElementById('child') should return you the correct element - remember that id's need to be unique across a document to make it valid anyway.

edit : see this page - ids MUST be unique.

edit edit : alternate way to solve the problem :

<div onclick="test('child1')">
    Test
    <div id="child1">child</div>
</div>

then you just need the test() function to look up the element by id that you passed in.

How to mock void methods with mockito - there are two options:

1. doAnswer - If we want our mocked void method to do something (mock the behavior despite being void).
2. doThrow - Then there is Mockito.doThrow() if you want to throw an exception from the mocked void method.

Following is an example of how to use it (not an ideal usecase but just wanted to illustrate the basic usage).

@Test
public void testUpdate() {

    doAnswer(new Answer<Void>() {

        @Override
        public Void answer(InvocationOnMock invocation) throws Throwable {
            Object[] arguments = invocation.getArguments();
            if (arguments != null && arguments.length > 1 && arguments[0] != null && arguments[1] != null) {

                Customer customer = (Customer) arguments[0];
                String email = (String) arguments[1];
                customer.setEmail(email);

            }
            return null;
        }
    }).when(daoMock).updateEmail(any(Customer.class), any(String.class));

    // calling the method under test
    Customer customer = service.changeEmail("[email protected]", "[email protected]");

    //some asserts
    assertThat(customer, is(notNullValue()));
    assertThat(customer.getEmail(), is(equalTo("[email protected]")));

}

@Test(expected = RuntimeException.class)
public void testUpdate_throwsException() {

    doThrow(RuntimeException.class).when(daoMock).updateEmail(any(Customer.class), any(String.class));

    // calling the method under test
    Customer customer = service.changeEmail("[email protected]", "[email protected]");

}
}

Pure/vanilla JS solution (working example here)

// All elements with data-company="Microsoft" below "Companies"
let a = document.querySelectorAll("[data-group='Companies'] [data-company='Microsoft']"); 

// All elements with data-company!="Microsoft" below "Companies"
let b = document.querySelectorAll("[data-group='Companies'] :not([data-company='Microsoft'])"); 

In querySelectorAll you must use valid CSS selector (currently Level3)

SPEED TEST (2018.06.29) for jQuery and Pure JS: test was performed on MacOs High Sierra 10.13.3 on Chrome 67.0.3396.99 (64-bit), Safari 11.0.3 (13604.5.6), Firefox 59.0.2 (64-bit). Below screenshot shows results for fastest browser (Safari):

PureJS was faster than jQuery about 12% on Chrome, 21% on Firefox and 25% on Safari. Interestingly speed for Chrome was 18.9M operation per second, Firefox 26M, Safari 160.9M (!).

So winner is PureJS and fastest browser is Safari (more than 8x faster than Chrome!)

Timezones. You have to deal with them, by using getTimezoneOffset() if you want your visitors from around the wolrd to get the same time.

Try this http://jsfiddle.net/cxyms/2/, it works for me, but I'm not sure will it work with other timezones.

var eventTimeStamp = '1366549200'; // Timestamp - Sun, 21 Apr 2013 13:00:00 GMT
var currentTimeStamp = '1366547400'; // Timestamp - Sun, 21 Apr 2013 12:30:00 GMT

var eventTime = new Date();
eventTime.setTime(366549200);

var Offset = new Date(eventTime.getTimezoneOffset()*60000)

var Diff = eventTimeStamp - currentTimeStamp + (Offset.getTime() / 2);
var duration = moment.duration(Diff, 'milliseconds');
var interval = 1000;

setInterval(function(){
  duration = moment.duration(duration.asMilliseconds() - interval, 'milliseconds');
  $('.countdown').text(moment(duration.asMilliseconds()).format('H[h]:mm[m]:ss[s]'));
}, interval);

I can't say this is the most bulletproof or portable solution, but it works for my testing scripts:

.output /tmp/temp_drop_tables.sql
select 'drop table ' || name || ';' from sqlite_master where type = 'table';
.output stdout
.read /tmp/temp_drop_tables.sql
.system rm /tmp/temp_drop_tables.sql

This bit of code redirects output to a temporary file, constructs the 'drop table' commands that I want to run (sending the commands to the temp file), sets output back to standard out, then executes the commands from the file, and finally removes the file.

Try this:

apt-get install lib32stdc++6

TL;DR

a) the method/function only reads the array argument => implicit (internal) reference
b) the method/function modifies the array argument => value
c) the method/function array argument is explicitly marked as a reference (with an ampersand) => explicit (user-land) reference

Or this:
- non-ampersand array param: passed by reference; the writing operations alter a new copy of the array, copy which is created on the first write;
- ampersand array param: passed by reference; the writing operations alter the original array.

Remember - PHP does a value-copy the moment you write to the non-ampersand array param. That's what copy-on-write means. I'd love to show you the C source of this behaviour, but it's scary in there. Better use xdebug_debug_zval().

Pascal MARTIN was right. Kosta Kontos was even more so.

Answer

It depends.

Long version

I think I'm writing this down for myself. I should have a blog or something...

Whenever people talk of references (or pointers, for that matter), they usually end up in a logomachy (just look at this thread!).
PHP being a venerable language, I thought I should add up to the confusion (even though this a summary of the above answers). Because, although two people can be right at the same time, you're better off just cracking their heads together into one answer.

First off, you should know that you're not a pedant if you don't answer in a black-and-white manner. Things are more complicated than "yes/no".

As you will see, the whole by-value/by-reference thing is very much related to what exactly are you doing with that array in your method/function scope: reading it or modifying it?

What does PHP says? (aka "change-wise")

The manual says this (emphasis mine):

By default, function arguments are passed by value (so that if the value of the argument within the function is changed, it does not get changed outside of the function). To allow a function to modify its arguments, they must be passed by reference.

To have an argument to a function always passed by reference, prepend an ampersand (&) to the argument name in the function definition

As far as I can tell, when big, serious, honest-to-God programmers talk about references, they usually talk about altering the value of that reference. And that's exactly what the manual talks about: hey, if you want to CHANGE the value in a function, consider that PHP's doing "pass-by-value".

There's another case that they don't mention, though: what if I don't change anything - just read?
What if you pass an array to a method which doesn't explicitly marks a reference, and we don't change that array in the function scope? E.g.:

<?php
function readAndDoStuffWithAnArray($array) 
{
    return $array[0] + $array[1] + $array[2];
}

$x = array(1, 2, 3);

echo readAndDoStuffWithAnArray($x);

Read on, my fellow traveller.

What does PHP actually do? (aka "memory-wise")

The same big and serious programmers, when they get even more serious, they talk about "memory optimizations" in regards to references. So does PHP. Because PHP is a dynamic, loosely typed language, that uses copy-on-write and reference counting, that's why.

It wouldn't be ideal to pass HUGE arrays to various functions, and PHP to make copies of them (that's what "pass-by-value" does, after all):

<?php

// filling an array with 10000 elements of int 1
// let's say it grabs 3 mb from your RAM
$x = array_fill(0, 10000, 1); 

// pass by value, right? RIGHT?
function readArray($arr) { // <-- a new symbol (variable) gets created here
    echo count($arr); // let's just read the array
}

readArray($x);

Well now, if this actually was pass-by-value, we'd have some 3mb+ RAM gone, because there are two copies of that array, right?

Wrong. As long as we don't change the $arr variable, that's a reference, memory-wise. You just don't see it. That's why PHP mentions user-land references when talking about &$someVar, to distinguish between internal and explicit (with ampersand) ones.

Facts

So, when an array is passed as an argument to a method or function is it passed by reference?

I came up with three (yeah, three) cases:
a) the method/function only reads the array argument
b) the method/function modifies the array argument
c) the method/function array argument is explicitly marked as a reference (with an ampersand)

Firstly, let's see how much memory that array actually eats (run here):

<?php
$start_memory = memory_get_usage();
$x = array_fill(0, 10000, 1);
echo memory_get_usage() - $start_memory; // 1331840

That many bytes. Great.

a) the method/function only reads the array argument

Now let's make a function which only reads the said array as an argument and we'll see how much memory the reading logic takes:

<?php

function printUsedMemory($arr) 
{
    $start_memory = memory_get_usage();

    count($arr);       // read
    $x = $arr[0];      // read (+ minor assignment)
    $arr[0] - $arr[1]; // read

    echo memory_get_usage() - $start_memory; // let's see the memory used whilst reading
}

$x = array_fill(0, 10000, 1); // this is 1331840 bytes
printUsedMemory($x);

Wanna guess? I get 80! See for yourself. This is the part that the PHP manual omits. If the $arr param was actually passed-by-value, you'd see something similar to 1331840 bytes. It seems that $arr behaves like a reference, doesn't it? That's because it is a references - an internal one.

b) the method/function modifies the array argument

Now, let's write to that param, instead of reading from it:

<?php

function printUsedMemory($arr)
{
    $start_memory = memory_get_usage();

    $arr[0] = 1; // WRITE!

    echo memory_get_usage() - $start_memory; // let's see the memory used whilst reading
}

$x = array_fill(0, 10000, 1);
printUsedMemory($x);

Again, see for yourself, but, for me, that's pretty close to being 1331840. So in this case, the array is actually being copied to $arr.

c) the method/function array argument is explicitly marked as a reference (with an ampersand)

Now let's see how much memory a write operation to an explicit reference takes (run here) - note the ampersand in the function signature:

<?php

function printUsedMemory(&$arr) // <----- explicit, user-land, pass-by-reference
{
    $start_memory = memory_get_usage();

    $arr[0] = 1; // WRITE!

    echo memory_get_usage() - $start_memory; // let's see the memory used whilst reading
}

$x = array_fill(0, 10000, 1);
printUsedMemory($x);

My bet is that you get 200 max! So this eats approximately as much memory as reading from a non-ampersand param.

Choose Database | Set Datasource Location... Select the database node (yellow-ish cylinder) of the current connection, then select the database node of the desired connection (you may need to authenticate), then click Update.

You will need to do this for the 'Subreports' nodes as well.

FYI, you can also do individual tables by selecting each individually, then choosing Update.

It is better to remove NodeJS and its modules manually because installation leaves a lot of files, links and modules behind and later this creates problems when we reconfigure another version of NodeJS and its modules.

To remove the files, run the following commands:

sudo rm -rf /usr/local/bin/npm 
sudo rm -rf /usr/local/share/man/man1/node* 
sudo rm -rf /usr/local/lib/dtrace/node.d
rm -rf ~/.npm
rm -rf ~/.node-gyp
sudo rm -rf /opt/local/bin/node
sudo rm -rf /opt/local/include/node
sudo rm -rf /opt/local/lib/node_modules
sudo rm -rf /usr/local/lib/node*
sudo rm -rf /usr/local/include/node*
sudo rm -rf /usr/local/bin/node*

If you are looking for non remote options:

On earlier and non rooted Jellybean releases a logcat viewer can be used if android.permission.READL_LOGS is granted via adb once.

On firefox, there is a console addon that reads and shows all app logs and there is also firebug lite.

class Gift
  def to_hash
    instance_variables.map do |var|
      [var[1..-1].to_sym, instance_variable_get(var)]
    end.to_h
  end
end

Try this:

mynewlist = [s for s in mylist if s.isdigit()]

From the docs:

str.isdigit()

Return true if all characters in the string are digits and there is at least one character, false otherwise.

For 8-bit strings, this method is locale-dependent.

As noted in the comments, isdigit() returning True does not necessarily indicate that the string can be parsed as an int via the int() function, and it returning False does not necessarily indicate that it cannot be. Nevertheless, the approach above should work in your case.

It's simply pointless to create variable variable names. Why?

• They are unnecessary: You can store everything in lists, dictionarys and so on
• They are hard to create: You have to use exec or globals()
• You can't use them: How do you write code that uses these variables? You have to use exec/globals() again

Using a list is much easier:

# 8 strings: `Hello String 0, .. ,Hello String 8`
strings = ["Hello String %d" % x for x in range(9)]
for string in strings: # you can loop over them
    print string
print string[6] # or pick any of them

The accepted answer is not ideal, so I decided to add my 2 cents

timeStamp.toLocalDateTime().toLocalDate();

is a bad solution in general, I'm not even sure why they added this method to the JDK as it makes things really confusing by doing an implicit conversion using the system timezone. Usually when using only java8 date classes the programmer is forced to specify a timezone which is a good thing.

The good solution is

timestamp.toInstant().atZone(zoneId).toLocalDate()

Where zoneId is the timezone you want to use which is typically either ZoneId.systemDefault() if you want to use your system timezone or some hardcoded timezone like ZoneOffset.UTC

The general approach should be

1. Break free to the new java8 date classes using a class that is directly related, e.g. in our case java.time.Instant is directly related to java.sql.Timestamp, i.e. no timezone conversions are needed between them.
2. Use the well-designed methods in this java8 class to do the right thing. In our case atZone(zoneId) made it explicit that we are doing a conversion and using a particular timezone for it.

Have you tried (from a command line)

java -jar jbpm-installer-3.2.7.jar

or double clicking it with the mouse ?

Found this and this by googling.

Hope it helps

My syntax error was semi-hidden in an f-string

 print(f'num_flex_rows = {self.}\nFlex Rows = {flex_rows}\nMax elements = {max_elements}')

should be

 print(f'num_flex_rows = {self.num_rows}\nFlex Rows = {flex_rows}\nMax elements = {max_elements}')

It didn't have the PyCharm spell-check-red line under the error.

It did give me a clue, yet when I searched on this error message, it of course did not find the error in that bit of code above.

Had I looked more closely at the error message, I would have found the '' in the error. Seeing Line 1 was discouraging and thus wasn't paying close attention :-( Searching for

self.)

yielded nothing. Searching for

self.

yielded practically everything :-\

If I can help you avoid even a minute longer of deskchecking your code, then mission accomplished :-)

To get all the elements starting with "jander" you should use:

$("[id^=jander]")

To get those that end with "jander"

$("[id$=jander]")

You can also use v-model for the rescue

<template>
    <select name="LeaveType" v-model="leaveType" @change="onChange()" class="form-control">
         <option value="1">Annual Leave/ Off-Day</option>
         <option value="2">On Demand Leave</option>
    </select>
</template>

<script>
export default {
    data() {
        return {
            leaveType: '',
        }
    },

    methods: {
        onChange() {
            console.log('The new value is: ', this.leaveType)
        }
    }
}

java -cp CLASSPATH is necesssary if you wish to specify all code in the classpath. This is useful for debugging code.

The jarred executable format: java -jar JarFile can be used if you wish to start the app with a single short command. You can specify additional dependent jar files in your MANIFEST using space separated jars in a Class-Path entry, e.g.:

Class-Path: mysql.jar infobus.jar acme/beans.jar

Both are comparable in terms of performance.

I think you're looking for: SELECT a, b, COUNT(a) FROM tbl GROUP BY a, b

I want to make a popup box centered to the screen with dynamic width and height.

Here is a modern approach for horizontally centering an element with a dynamic width - it works in all modern browsers; support can be seen here.

Updated Example

.jqbox_innerhtml {
    position: fixed;
    left: 50%;
    transform: translateX(-50%);
}

For both vertical and horizontal centering you could use the following:

Updated Example

.jqbox_innerhtml {
    position: fixed;
    left: 50%;
    top: 50%;
    transform: translate(-50%, -50%);
}

You may wish to add in more vendor prefixed properties too (see the examples).

You can't.

As a workaround you can use a // @ts-nocheck comment at the top of a file to disable type-checking for that file: https://devblogs.microsoft.com/typescript/announcing-typescript-3-7-beta/

So to disable checking for a block (function, class, etc.), you can move it into its own file, then use the comment/flag above. (This isn't as flexible as block-based disabling of course, but it's the best option available at the moment.)

Try this

keys = [next(iter(x.keys())) for x in test]
print(list(keys))

The result looks like this. ['foo', 'hello']

You can find more possible solutions here.

end 2017 / 2018: the anothers answers have too much old code to edit, so here my alternative clean answer:

with require

let moment = require('moment');
require('moment/locale/fr.js');
// or if you want to include all locales:
require("moment/min/locales.min");

with imports

import moment from 'moment';
import 'moment/locale/fr';
// or if you want to include all locales:
require("moment/min/locales.min");

Use:

moment.locale('fr');
moment().format('D MMM YY');  // Correct, set default global format 
// moment.locale('fr').format('D MMM YY') //Wrong old versions for global default format

with timezone

*require:

require('moment-range');
require('moment-timezone');

*import:

import 'moment-range';
import 'moment-timezone';

use zones:

const newYork    = moment.tz("2014-06-01 12:00", "America/New_York");
const losAngeles = newYork.clone().tz("America/Los_Angeles");
const london     = newYork.clone().tz("Europe/London");

function to format date

const ISOtoDate = function (dateString, format='') {

 // if date is not string use conversion:
 // value.toLocaleDateString() +' '+ value.toLocaleTimeString();

  if ( !dateString ) {
    return '';
  }

  if (format ) {
    return moment(dateString).format(format);
  } else  {
    return moment(dateString);  // It will use default global format
  }  
};

Python 3 renamed the unicode type to str, the old str type has been replaced by bytes.

if isinstance(unicode_or_str, str):
    text = unicode_or_str
    decoded = False
else:
    text = unicode_or_str.decode(encoding)
    decoded = True

You may want to read the Python 3 porting HOWTO for more such details. There is also Lennart Regebro's Porting to Python 3: An in-depth guide, free online.

Last but not least, you could just try to use the 2to3 tool to see how that translates the code for you.

you need to have mysql connector jar in your classpath.

in Java JDBC API makes everything with databases. using JDBC we can write Java applications to
1. Send queries or update SQL to DB(any relational Database) 2. Retrieve and process the results from DB

with below three steps we can able to retrieve data from any Database

Connection con = DriverManager.getConnection(
                     "jdbc:myDriver:DatabaseName",
                     dBuserName,
                     dBuserPassword);

Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM Table");

while (rs.next()) {
    int x = rs.getInt("a");
    String s = rs.getString("b");
    float f = rs.getFloat("c");
}

Assume you have a local branch "Branch-200" (or other name) and server repository contains "origin/Branch-1". If you have local "Branch-1" not linked with "origin/Branch-1", rename it to "Branch-200".

In Android Studio checkout to "origin/Branch-1" creating a new local branch "Branch-1", then merge with you local branch "Branch-200".

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

A simple example: We have the following array

li = [{"id":1,"name":"ronaldo"},{"id":2,"name":"messi"}]

Now, we want to find the object in the array that has id equal to 1

1. Use method next with list comprehension

next(x for x in li if x["id"] == 1 )

2. Use list comprehension and return first item

[x for x in li if x["id"] == 1 ][0]

3. Custom Function

def find(arr , id):
    for x in arr:
        if x["id"] == id:
            return x
find(li , 1)

Output all the above methods is {'id': 1, 'name': 'ronaldo'}

I managed to get the environment version working by setting the EDITOR variable using quotes and /:

EDITOR="c:/Program Files (x86)/Notepad++/notepad++.exe"

Like this:

var str = 'blah blah blah';
str += ' blah';

str += ' ' + 'and some more blah';

const double pi = boost::math::constants::pi<double>();

cv::Mat distance2ellipse(cv::Mat image, cv::RotatedRect ellipse){
    float distance = 2.0f;
    float angle = ellipse.angle;
    cv::Point ellipse_center = ellipse.center;
    float major_axis = ellipse.size.width/2;
    float minor_axis = ellipse.size.height/2;
    cv::Point pixel;
    float a,b,c,d;

    for(int x = 0; x < image.cols; x++)
    {
        for(int y = 0; y < image.rows; y++) 
        {
        auto u =  cos(angle*pi/180)*(x-ellipse_center.x) + sin(angle*pi/180)*(y-ellipse_center.y);
        auto v = -sin(angle*pi/180)*(x-ellipse_center.x) + cos(angle*pi/180)*(y-ellipse_center.y);

        distance = (u/major_axis)*(u/major_axis) + (v/minor_axis)*(v/minor_axis);  

        if(distance<=1)
        {
            image.at<cv::Vec3b>(y,x)[1] = 255;
        }
      }
  }
  return image;  
}

str = str.replace(/abc/g, '');

Or try the replaceAll function from here:

What are useful JavaScript methods that extends built-in objects?

str = str.replaceAll('abc', ''); OR

var search = 'abc';
str = str.replaceAll(search, '');

EDIT: Clarification about replaceAll availability

The 'replaceAll' method is added to String's prototype. This means it will be available for all string objects/literals.

E.g.

var output = "test this".replaceAll('this', 'that');  //output is 'test that'.
output = output.replaceAll('that', 'this'); //output is 'test this'

/*

If your delimiters are slash-based, escape it:

\/*

* means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.

Maybe it's not pythonic way, but you can do this

import ctypes

def incr(a):
    a += 1

x = ctypes.c_int(1) # create c-var
incr(ctypes.ctypes.byref(x)) # passing by ref

in controller

For example

return redirect('login')->with('message',$message);

in blade file The message will store in session not in variable.

For example

@if(session('message'))
{{ session('message') }}
@endif

Set Jquery in scope

$scope.$ = $;

and call in html

ng-click="$('#novoModelo').modal('show')"

You can get that error if you have an object with the same name as the schema. For example:

create sequence s2;

begin
  s2.a;
end;
/

ORA-06550: line 2, column 6:
PLS-00302: component 'A' must be declared
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored

When you refer to S2.MY_FUNC2 the object name is being resolved so it doesn't try to evaluate S2 as a schema name. When you just call it as MY_FUNC2 there is no confusion, so it works.

The documentation explains name resolution. The first piece of the qualified object name - S2 here - is evaluated as an object on the current schema before it is evaluated as a different schema.

It might not be a sequence; other objects can cause the same error. You can check for the existence of objects with the same name by querying the data dictionary.

select owner, object_type, object_name
from all_objects
where object_name = 'S2';

Simple use this to show the alert message box in code behind.

ScriptManager.RegisterStartupScript(this, this.GetType(), "script", "alert('Record Saved Sucessfully');", true);

A PDOStatement (which you have in $users) is a forward-cursor. That means, once consumed (the first foreach iteration), it won't rewind to the beginning of the resultset.

You can close the cursor after the foreach and execute the statement again:

$users       = $dbh->query($sql);
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

$users->execute();

foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

Or you could cache using tailored CachingIterator with a fullcache:

$users       = $dbh->query($sql);

$usersCached = new CachedPDOStatement($users);

foreach ($usersCached as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
foreach ($usersCached as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

You find the CachedPDOStatement class as a gist. The caching itertor is probably more sane than storing the resultset into an array because it still offers all properties and methods of the PDOStatement object it has wrapped.

As of Rails 2.3.9, there is a setting in config/application.rb in which you can specify directories that contain files you want autoloaded.

From application.rb:

# Custom directories with classes and modules you want to be autoloadable.
# config.autoload_paths += %W(#{config.root}/extras)

As an alternative to pathinfo(), you can use

• basename() — Returns filename component of path

Example from PHP manual

$path = "/home/httpd/html/index.php";
$file = basename($path);         // $file is set to "index.php"
$file = basename($path, ".php"); // $file is set to "index"

You have to know the extension to remove it in advance though.

However, since your question suggests you have the need for getting the extension and the basename, I'd vote Pekka's answer as the most useful one, because it will give you any info you'd want about the path and file with one single native function.

Try this:

SELECT * FROM USERS LIMIT 10;

Nothing worked for me. I needed to delete all files in bin and obj folders for debug and release. My solution:

1.Right click project, unload, right click again edit, go to bottom

2.Insert

<Target Name="DeleteBinObjFolders" BeforeTargets="Clean">
  <RemoveDir Directories="..\..\Publish" />
  <RemoveDir Directories=".\bin" />
  <RemoveDir Directories="$(BaseIntermediateOutputPath)" />
</Target>

3. Save, reload project, right click clean and presto.

starting from the chad's answer, here is the COMPLETE working solution to parse UML, with propper handling of comments, with just 2 little functions (more than 2 bu you can mix them all). I don't say chad's one didn't work at all, but it had too much issues with badly formated XML files: So you have to be a bit more tricky to handle comments and misplaced spaces/CR/TAB/etc.

The purpose of this answer is to give ready-2-use, out of the box bash functions to anyone needing parsing UML without complex tools using perl, python or anything else. As for me, I cannot install cpan, nor perl modules for the old production OS i'm working on, and python isn't available.

First, a definition of the UML words used in this post:

<!-- comment... -->
<tag attribute="value">content...</tag>

EDIT: updated functions, with handle of:

• Websphere xml (xmi and xmlns attributes)
• must have a compatible terminal with 256 colors
• 24 shades of grey
• compatibility added for IBM AIX bash 3.2.16(1)

The functions, first is the xml_read_dom which's called recursively by xml_read:

  TAG_NAME=${ENTITY%%[[:space:]]*}
  [ "x${TAG_NAME}x" == "x?xmlx" ] && TAG_NAME=xml

  ATTRIBUTES=${ENTITY#*[[:space:]]}
  ATTRIBUTES="${ATTRIBUTES//xmi:/}"

How to load all that stuff:

Either you know how to create functions and load them via FPATH (ksh) or an emulation of FPATH (bash)

If not, just copy/paste everything on the command line.

How does it work:

xml_read [-cdlp] [-x command <-a attribute>] <file.xml> [tag | "any"] [attributes .. | "content"]
  -c = NOCOLOR
  -d = Debug
  -l = LIGHT (no \"attribute=\" printed)
  -p = FORCE PRINT (when no attributes given)
  -x = apply a command on an attribute and print the result instead of the former value, in green color
  (no attribute given will load their values into your shell as $ATTRIBUTE=value; use '-p' to print them as well)

xml_read server.xml title content     # print content between <title></title>
xml_read server.xml Connector port    # print all port values from Connector tags
xml_read server.xml any port          # print all port values from any tags

With Debug mode (-d) comments and parsed attributes are printed to stderr

I got similar error msgs. I run svn clean-up, and then tried "get clock" for a few times. Then this error was gone.

In HTML5 as such, there is no way to set the default value of the date field to today’s date? As shown in other answers, the value can be set using JavaScript, and this is usually the best approach if you wish to set the default according to what is current date to the user when the page is loaded.

HTML5 defines the valueAsDate property for input type=date elements, and using it, you could set the initial value directly from an object created e.g. by new Date(). However, e.g. IE 10 does not know that property. (It also lacks genuine support to input type=date, but that’s a different issue.)

So in practice you need to set the value property, and it must be in ISO 8601 conformant notation. Nowadays this can be done rather easily, since we can expect currenty used browsers to support the toISOString method:

<input type=date id=e>
<script>
document.getElementById('e').value = new Date().toISOString().substring(0, 10);
</script>

I'm just beginner to help you for getting edittext value to textview. Try out this code -

EditText edit = (EditText)findViewById(R.id.editext1);
TextView tview = (TextView)findViewById(R.id.textview1);
String result = edit.getText().toString();
tview.setText(result);

This will get the text which is in EditText Hope this helps you.

Try or:

WHERE id = 3 or id = 4

Or the equivalent in:

WHERE id in (3,4)

Approximate solution:

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
ctx.font = "100px Arial";
var txt = "Hello guys!"
var wt = ctx.measureText(txt).width;
var height = wt / txt.length;

This will be accurate result in monospaced font.

Here is my approach to making a structure array from a pandas DataFrame.

Create the data frame

import pandas as pd
import numpy as np
import six

NaN = float('nan')
ID = [1, 2, 3, 4, 5, 6, 7]
A = [NaN, NaN, NaN, 0.1, 0.1, 0.1, 0.1]
B = [0.2, NaN, 0.2, 0.2, 0.2, NaN, NaN]
C = [NaN, 0.5, 0.5, NaN, 0.5, 0.5, NaN]
columns = {'A':A, 'B':B, 'C':C}
df = pd.DataFrame(columns, index=ID)
df.index.name = 'ID'
print(df)

      A    B    C
ID               
1   NaN  0.2  NaN
2   NaN  NaN  0.5
3   NaN  0.2  0.5
4   0.1  0.2  NaN
5   0.1  0.2  0.5
6   0.1  NaN  0.5
7   0.1  NaN  NaN

Define function to make a numpy structure array (not a record array) from a pandas DataFrame.

def df_to_sarray(df):
    """
    Convert a pandas DataFrame object to a numpy structured array.
    This is functionally equivalent to but more efficient than
    np.array(df.to_array())

    :param df: the data frame to convert
    :return: a numpy structured array representation of df
    """

    v = df.values
    cols = df.columns

    if six.PY2:  # python 2 needs .encode() but 3 does not
        types = [(cols[i].encode(), df[k].dtype.type) for (i, k) in enumerate(cols)]
    else:
        types = [(cols[i], df[k].dtype.type) for (i, k) in enumerate(cols)]
    dtype = np.dtype(types)
    z = np.zeros(v.shape[0], dtype)
    for (i, k) in enumerate(z.dtype.names):
        z[k] = v[:, i]
    return z

Use reset_index to make a new data frame that includes the index as part of its data. Convert that data frame to a structure array.

sa = df_to_sarray(df.reset_index())
sa

array([(1L, nan, 0.2, nan), (2L, nan, nan, 0.5), (3L, nan, 0.2, 0.5),
       (4L, 0.1, 0.2, nan), (5L, 0.1, 0.2, 0.5), (6L, 0.1, nan, 0.5),
       (7L, 0.1, nan, nan)], 
      dtype=[('ID', '<i8'), ('A', '<f8'), ('B', '<f8'), ('C', '<f8')])

EDIT: Updated df_to_sarray to avoid error calling .encode() with python 3. Thanks to Joseph Garvin and halcyon for their comment and solution.

Since it depends on the version of your JRE which is used to run the maven command you propably dont want to disable DocLint per default in your pom.xml

Hence, from command line you can use the switch -Dadditionalparam=-Xdoclint:none.

Example: mvn clean install -Dadditionalparam=-Xdoclint:none

According to a discussion with Android Developers on Google+, running the new Map API on the emulator is not possible at the moment.

(The comment is from Zhelyazko Atanasov yesterday at 23:18, I don't know how to link directly to it)

Also, you don't see the "(via Bazaar)" part when running from an actual device, and the update button open the Play Store. I am assuming Bazaar is meant to provide Google Play Services on the Android emulator, but it is not ready yet...

You can find an example below. Basically you attach a function to window's scroll event and trace scrollTop property and if it's higher than desired threshold you apply position: fixed and some other css properties.

jQuery(function($) {_x000D_
  $(window).scroll(function fix_element() {_x000D_
    $('#target').css(_x000D_
      $(window).scrollTop() > 100_x000D_
        ? { 'position': 'fixed', 'top': '10px' }_x000D_
        : { 'position': 'relative', 'top': 'auto' }_x000D_
    );_x000D_
    return fix_element;_x000D_
  }());_x000D_
});

body {_x000D_
  height: 2000px;_x000D_
  padding-top: 100px;_x000D_
}_x000D_
code {_x000D_
  padding: 5px;_x000D_
  background: #efefef;_x000D_
}_x000D_
#target {_x000D_
  color: #c00;_x000D_
  font: 15px arial;_x000D_
  padding: 10px;_x000D_
  margin: 10px;_x000D_
  border: 1px solid #c00;_x000D_
  width: 200px;_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div id="target">This <code>div</code> is going to be fixed</div>

You can do a printf to anything that is an OutputStream with a PrintStream. Somehow like this, printing into a string stream:

PrintStream ps = new PrintStream(baos);
ps.printf("there is a %s from %d %s", "hello", 3, "friends");
System.out.println(baos.toString());
baos.reset(); //need reset to write new string
ps.printf("there is a %s from %d %s", "flip", 5, "haters");
System.out.println(baos.toString());
baos.reset();

The string stream can be created like this ByteArrayOutputStream:

ByteArrayOutputStream baos = new ByteArrayOutputStream();

With pure javascript:

this === document.activeElement // where 'this' is a dom object

or with jquery's :focus pseudo selector.

$(this).is(':focus');

As per this link:

if (typeof jQuery == 'undefined') {
    // jQuery IS NOT loaded, do stuff here.
}

there are a few more in comments of the link as well like,

if (typeof jQuery == 'function') {...}

//or

if (typeof $== 'function') {...}

// or

if (jQuery) {
    alert("jquery is loaded");
} else {
    alert("Not loaded");
}

Hope this covers most of the good ways to get this thing done!!

you can use between too:

SELECT Table.date
  FROM Table 
  WHERE date between current_date and current_date - interval '10 day';

If you list the bakground-none class after the other classes, its properties will override those already set. There is no need to use !important here.

For example:

.red { background-color: red; }
.background-none { background: none; }

and

<a class="red background-none" href="#carousel">...</a>

The link will not have a red background. Please note that this only overrides properties that have a selector that is less or equally specific.

Several of the answers above will work around the lack of a direct reference to a specific row, but will not work if changes occur to the other rows in a table. That is my criteria for which answers fall technically short.

A common use of Oracle's ROWID is to provide a (somewhat) stable method of selecting rows and later returning to the row to process it (e.g., to UPDATE it). The method of finding a row (complex joins, full-text searching, or browsing row-by-row and applying procedural tests against the data) may not be easily or safely re-used to qualify the UPDATE statement.

The SQL Server RID seems to provide the same functionality, but does not provide the same performance. That is the only issue I see, and unfortunately the purpose of retaining a ROWID is to avoid repeating an expensive operation to find the row in, say, a very large table. Nonetheless, performance for many cases is acceptable. If Microsoft adjusts the optimizer in a future release, the performance issue could be addressed.

It is also possible to simply use FOR UPDATE and keep the CURSOR open in a procedural program. However, this could prove expensive in large or complex batch processing.

Caveat: Even Oracle's ROWID would not be stable if the DBA, between the SELECT and the UPDATE, for example, were to rebuild the database, because it is the physical row identifier. So the ROWID device should only be used within a well-scoped task.

I think the better way to go is to put switch to named functions (Check this overflow for more on that subject). That way you can call them from a single event.

Like so:

function firstFunction() {
    console.log("first");
}

function secondFunction() {
    console.log("second");
}


function thirdFunction() {
    console.log("third");
}

That way you can load them in a single ready function.

jQuery(document).on('ready', function(){
   firstFunction();
   secondFunction();
   thirdFunction();

});

This will output the following to your console.log:

first
second
third

This way you can reuse the functions for other events.

jQuery(window).on('resize',function(){
    secondFunction();
});

the css odd and even is not support for IE. recommend you using solution below.

Best solution:

li:nth-child(2n+1) { color:green; } // for odd
li:nth-child(2n+2) { color:red; } // for even

li:nth-child(1n) { color:green; }
li:nth-child(2n) { color:red; }

<ul>
  <li>list element 1</li>
  <li>list element 2</li>
  <li>list element 3</li>
  <li>list element 4</li>
</ul>

definetly +1 for VisualAssistX (cannot work without it anymore & it's worth all the money) and +1 for VisualSVN

Still using indirect. Say your A1 cell is your variable that will contain the name of the referenced sheet (Jan). If you go by:

=INDIRECT(CONCATENATE("'",A1," Item'", "!J3"))

Then you will have the 'Jan Item'!J3 value.

The answer depends on what do you need a loop for.

of course you can have a loop similar to Java:

for i in xrange(len(my_list)):

but I never actually used loops like this,

because usually you want to iterate

for obj in my_list

or if you need an index as well

for index, obj in enumerate(my_list)

or you want to produce another collection from a list

map(some_func, my_list)

[somefunc[x] for x in my_list]

also there are itertools module that covers most of iteration related cases

also please take a look at the builtins like any, max, min, all, enumerate

I would say - do not try to write Java-like code in python. There is always a pythonic way to do it.
