This way you can Create NSArray, NSMutableArray.

NSArray keys =[NSArray arrayWithObjects:@"key1",@"key2",@"key3",nil];

NSArray objects =[NSArray arrayWithObjects:@"value1",@"value2",@"value3",nil];

We can copy all columns from one table to another, existing table:

INSERT INTO table2 SELECT * FROM table1;

Or we can copy only the columns we want to into another, existing table:

INSERT INTO table2 (column_name(s)) SELECT column_name(s) FROM table1;

or SELECT * INTO BACKUP_TABLE1 FROM TABLE1

Here is a simple program that displays the camera feed in a cv2.namedWindow and will take a snapshot when you hit SPACE. It will also quit if you hit ESC.

import cv2

cam = cv2.VideoCapture(0)

cv2.namedWindow("test")

img_counter = 0

while True:
    ret, frame = cam.read()
    if not ret:
        print("failed to grab frame")
        break
    cv2.imshow("test", frame)

    k = cv2.waitKey(1)
    if k%256 == 27:
        # ESC pressed
        print("Escape hit, closing...")
        break
    elif k%256 == 32:
        # SPACE pressed
        img_name = "opencv_frame_{}.png".format(img_counter)
        cv2.imwrite(img_name, frame)
        print("{} written!".format(img_name))
        img_counter += 1

cam.release()

cv2.destroyAllWindows()

I think this should answer your question for the most part. If there is any line of it that you don't understand let me know and I'll add comments.

If you need to grab multiple images per press of the SPACE key, you will need an inner loop or perhaps just make a function that grabs a certain number of images.

Note that the key events are from the cv2.namedWindow so it has to have focus.

All answers here provide good and working code. But someone would be dissatisfied that they all use ContentType as return type and not JsonResult.

Unfortunately JsonResult is using JavaScriptSerializer without option to disable it. The best way to get around this is to inherit JsonResult.

I copied most of the code from original JsonResult and created JsonStringResult class that returns passed string as application/json. Code for this class is below

public class JsonStringResult : JsonResult
    {
        public JsonStringResult(string data)
        {
            JsonRequestBehavior = JsonRequestBehavior.DenyGet;
            Data = data;
        }

        public override void ExecuteResult(ControllerContext context)
        {
            if (context == null)
            {
                throw new ArgumentNullException("context");
            }
            if (JsonRequestBehavior == JsonRequestBehavior.DenyGet &&
                String.Equals(context.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase))
            {
                throw new InvalidOperationException("Get request is not allowed!");
            }

            HttpResponseBase response = context.HttpContext.Response;

            if (!String.IsNullOrEmpty(ContentType))
            {
                response.ContentType = ContentType;
            }
            else
            {
                response.ContentType = "application/json";
            }
            if (ContentEncoding != null)
            {
                response.ContentEncoding = ContentEncoding;
            }
            if (Data != null)
            {
                response.Write(Data);
            }
        }
    }

Example usage:

var json = JsonConvert.SerializeObject(data);
return new JsonStringResult(json);

A Relation object passes unknown method calls through to an Eloquent query Builder, which is set up to only select the related objects. That Builder in turn passes unknown method calls through to its underlying query Builder.

This means you can use the exists() or count() methods directly from a relation object:

$model->relation()->exists(); // bool: true if there is at least one row
$model->relation()->count(); // int: number of related rows

Note the parentheses after relation: ->relation() is a function call (getting the relation object), as opposed to ->relation which a magic property getter set up for you by Laravel (getting the related object/objects).

Using the count method on the relation object (that is, using the parentheses) will be much faster than doing $model->relation->count() or count($model->relation) (unless the relation has already been eager-loaded) since it runs a count query rather than pulling all of the data for any related objects from the database, just to count them. Likewise, using exists doesn't need to pull model data either.

Both exists() and count() work on all relation types I've tried, so at least belongsTo, hasOne, hasMany, and belongsToMany.

using (SqlConnection conn = new SqlConnection("Server=(local);DataBase=Northwind;Integrated Security=SSPI")) {
    conn.Open();

    // 1.  create a command object identifying the stored procedure
    SqlCommand cmd  = new SqlCommand("CustOrderHist", conn);

    // 2. set the command object so it knows to execute a stored procedure
    cmd.CommandType = CommandType.StoredProcedure;

    // 3. add parameter to command, which will be passed to the stored procedure
    cmd.Parameters.Add(new SqlParameter("@CustomerID", custId));

    // execute the command
    using (SqlDataReader rdr = cmd.ExecuteReader()) {
        // iterate through results, printing each to console
        while (rdr.Read())
        {
            Console.WriteLine("Product: {0,-35} Total: {1,2}",rdr["ProductName"],rdr["Total"]);
        }
    }
}

Using ...
search = (^.*import )(.*)(\(.*\):)
replace = $1$2

...replaces ...

from checks import checklist(_list):

...with...

from checks import checklist

Blocks in regex are delineated by parenthesis (which are not preceded by a "\")

(^.*import ) finds "from checks import " and loads it to $1 (eclipse starts counting at 1)

(.*) find the next "everything" until the next encountered "(" and loads it to $2. $2 stops at the "(" because of the next part (see next line below)

(\(.*\):) says "at the first encountered "(" after starting block $2...stop block $2 and start $3. $3 gets loaded with the "('any text'):" or, in the example, the "(_list):"

Then in the replace, just put the $1$2 to replace all three blocks with just the first two.

You will want to move the loop for the files outside of the loop for the folders. In addition you will need to pass the data structure holding the collection of files to each call of the method. That way all files go into a single list.

public static List<string> DirSearch(string sDir, List<string> files)
{
  foreach (string f in Directory.GetFiles(sDir, "*.xml"))
  {
    string extension = Path.GetExtension(f);
    if (extension != null && (extension.Equals(".xml")))
    {
      files.Add(f);
    }
  }
  foreach (string d in Directory.GetDirectories(sDir))
  {
    DirSearch(d, files);
  }
  return files;
}

Then call it like this.

List<string> files = DirSearch("c:\foo", new List<string>());

Update:

Well unbeknownst to me, until I read the other answer anyway, there is already a builtin mechanism for doing this. I will leave my answer in case you are interested in seeing how your code needs to be modified to make it work.

You can do it ... it may get a bit ugly and you'll be faced with some trial and error in terms of mapping types .. but heres the basic gist of it:

func FillStruct(data map[string]interface{}, result interface{}) {
    t := reflect.ValueOf(result).Elem()
    for k, v := range data {
        val := t.FieldByName(k)
        val.Set(reflect.ValueOf(v))
    }
}

Working sample: http://play.golang.org/p/PYHz63sbvL

Just a side note, in Python 2.0 you could compare anything to anything (int to string). As this wasn't explicit, it was changed in 3.0, which is a good thing as you are not running into the trouble of comparing senseless values with each other or when you forget to convert a type.

For those who want to improve the time for retrieval of records and dump into the file (i.e no processing on records), instead of putting them into an ArrayList, append those records into a StringBuffer. Apply toSring() function to get a single String and write it into the file at once.

For me, the retrieval time reduced from 22 seconds to 17 seconds.

When you write the statement

*src = "anotherstring";

the compiler sees the constant string "abcdefghijklmnop" like an array. Imagine you had written the following code instead:

char otherstring[14] = "anotherstring";
...
*src = otherstring;

Now, it's a bit clearer what is going on. The left-hand side, *src, refers to a char (since src is of type pointer-to-char) whereas the right-hand side, otherstring, refers to a pointer.

This isn't strictly forbidden because you may want to store the address that a pointer points to. However, an explicit cast is normally used in that case (which isn't too common of a case). The compiler is throwing up a red flag because your code is likely not doing what you think it is.

It appears to me that you are trying to assign a string. Strings in C aren't data types like they are in C++ and are instead implemented with char arrays. You can't directly assign values to a string like you are trying to do. Instead, you need to use functions like strncpy and friends from <string.h> and use char arrays instead of char pointers. If you merely want the pointer to point to a different static string, then drop the *.

I like best answer but if it is an empty string it returns true. So here's a fix:

function isJSON(MyTestStr){
    try {
        var MyJSON = JSON.stringify(MyTestStr);
        var json = JSON.parse(MyJSON);
        if(typeof(MyTestStr) == 'string')
            if(MyTestStr.length == 0)
                return false;
    }
    catch(e){
        return false;
    }
    return true;
}

public class Person
{
    // Before C# 6.0
    [Display(Name = "Age", ResourceType = typeof(Testi18n.Resource))]
    public string Age { get; set; }

    // After C# 6.0
    // [Display(Name = nameof(Resource.Age), ResourceType = typeof(Resource))]
}

1. Define ResourceType of the attribute so it looks for a resource

2. Define Name of the attribute which is used for the key of resource, after C# 6.0, you can use nameof for strong typed support instead of hard coding the key.

3. Set the culture of current thread in the controller.

Resource.Culture = CultureInfo.GetCultureInfo("zh-CN");

4. Set the accessibility of the resource to public

5. Display the label in cshtml like this

@Html.DisplayNameFor(model => model.Age)

The above answer is good, but if you need a version that can operate along different axes, here's a working implementation.

def entropy(A, axis=None):
    """Computes the Shannon entropy of the elements of A. Assumes A is 
    an array-like of nonnegative ints whose max value is approximately 
    the number of unique values present.

    >>> a = [0, 1]
    >>> entropy(a)
    1.0
    >>> A = np.c_[a, a]
    >>> entropy(A)
    1.0
    >>> A                   # doctest: +NORMALIZE_WHITESPACE
    array([[0, 0], [1, 1]])
    >>> entropy(A, axis=0)  # doctest: +NORMALIZE_WHITESPACE
    array([ 1., 1.])
    >>> entropy(A, axis=1)  # doctest: +NORMALIZE_WHITESPACE
    array([[ 0.], [ 0.]])
    >>> entropy([0, 0, 0])
    0.0
    >>> entropy([])
    0.0
    >>> entropy([5])
    0.0
    """
    if A is None or len(A) < 2:
        return 0.

    A = np.asarray(A)

    if axis is None:
        A = A.flatten()
        counts = np.bincount(A) # needs small, non-negative ints
        counts = counts[counts > 0]
        if len(counts) == 1:
            return 0. # avoid returning -0.0 to prevent weird doctests
        probs = counts / float(A.size)
        return -np.sum(probs * np.log2(probs))
    elif axis == 0:
        entropies = map(lambda col: entropy(col), A.T)
        return np.array(entropies)
    elif axis == 1:
        entropies = map(lambda row: entropy(row), A)
        return np.array(entropies).reshape((-1, 1))
    else:
        raise ValueError("unsupported axis: {}".format(axis))

Can't you style the forms themselves? Then, style the divs accordingly.

form
{
    /* styles */
}

You can always overrule inherited styles by making it important:

form
{
    /* styles */ !important
}

Just use Request.QueryString.ToString() to get full query string, like this:

string URL = "http://www.example.com/rendernews.php?"+Request.Querystring.ToString();

The difference concerns redirecting POST, PUT and DELETE requests and what the expectations of the server are for the user agent behavior (RFC 2616):

Note: RFC 1945 and RFC 2068 specify that the client is not allowed to change the method on the redirected request. However, most existing user agent implementations treat 302 as if it were a 303 response, performing a GET on the Location field-value regardless of the original request method. The status codes 303 and 307 have been added for servers that wish to make unambiguously clear which kind of reaction is expected of the client.

Also, read Wikipedia article on the 30x redirection codes.

Using JSTL:

<c:set var="message" value='${requestScope["Error_Message"]}' />

Here var sets the variable name and request.getAttribute is equal to requestScope. But it's not essential. ${Error_Message} will give you the same outcome. It'll search every scope. If you want to do some operation with content you take from Error_Message you have to do it using message. like below one.

<c:out value="${message}"/>

I'm guessing that you want something like

SELECT tab1.a, tab2.b, tab3.c, tab4.d
  FROM table1 tab1 
       JOIN table2 tab2 ON (tab1.fg = tab2.fg)
       LEFT OUTER JOIN table4 tab4 ON (tab1.ss = tab4.ss)
       LEFT OUTER JOIN table3 tab3 ON (tab4.xya = tab3.xya and tab3.desc = 'XYZ')
       LEFT OUTER JOIN table5 tab5 on (tab4.kk = tab5.kk AND
                                       tab3.dd = tab5.dd)

parent() method returns the direct parent element of the selected one. This method only traverse a single level up the DOM tree.

parents() method allows us to search through the ancestors of these elements in the DOM tree. Begin from given selector and move up.

The **.parents()** and **.parent()** methods are almost similar, except that the latter only travels a single level up the DOM tree. Also, **$( "html" ).parent()** method returns a set containing document whereas **$( "html" ).parents()** returns an empty set.

[closest()][3]method returns the first ancestor of the selected element.An ancestor is a parent, grandparent, great-grandparent, and so on.

This method traverse upwards from the current element, all the way up to the document's root element (<html>), to find the first ancestor of DOM elements.

According to docs:

**closest()** method is similar to **parents()**, in that they both traverse up the DOM tree. The differences are as follows:

**closest()**

Begins with the current element
Travels up the DOM tree and returns the first (single) ancestor that matches the passed expression
The returned jQuery object contains zero or one element

**parents()**

Begins with the parent element
Travels up the DOM tree and returns all ancestors that matches the passed expression
The returned jQuery object contains zero or more than one element





 

You can extract the html string from the PartialViewResult object, similar to the answer to this thread:

Render a view as a string

PartialViewResult and ViewResult both derive from ViewResultBase, so the same method should work on both.

Using the code from the thread above, you would be able to use:

public ActionResult ReturnSpecialJsonIfInvalid(AwesomenessModel model)
{
    if (ModelState.IsValid)
    {
        if(Request.IsAjaxRequest())
            return PartialView("NotEvil", model);
        return View(model)
    }
    if(Request.IsAjaxRequest())
    {
        return Json(new { error = true, message = RenderViewToString(PartialView("Evil", model))});
    }
    return View(model);
}

I think this is what you want:

/grand/parent/child[@id="#grand"]

This solution worked perfectly fine for me..

1) close XAMPP control

2) Open Activity Monitor(Launchpad->Other->Activity Monitor)

3) select filter for All processes (default is My processes)

4) in fulltext search type: httpd

5) kill all httpd items

6) relaunch XAMPP control and launch apache again

Hurray :)

Ugly but it at least gives the right dates back

With start of week set by system:

    public static DateTime FirstDateInWeek(this DateTime dt)
    {
        while (dt.DayOfWeek != System.Threading.Thread.CurrentThread.CurrentCulture.DateTimeFormat.FirstDayOfWeek)
            dt = dt.AddDays(-1);
        return dt;
    }

Without:

    public static DateTime FirstDateInWeek(this DateTime dt, DayOfWeek weekStartDay)
    {
        while (dt.DayOfWeek != weekStartDay)
            dt = dt.AddDays(-1);
        return dt;
    }

I think you're looking for the ndenumerate.

>>> a =numpy.array([[1,2],[3,4],[5,6]])
>>> for (x,y), value in numpy.ndenumerate(a):
...  print x,y
... 
0 0
0 1
1 0
1 1
2 0
2 1

Regarding the performance. It is a bit slower than a list comprehension.

X = np.zeros((100, 100, 100))

%timeit list([((i,j,k), X[i,j,k]) for i in range(X.shape[0]) for j in range(X.shape[1]) for k in range(X.shape[2])])
1 loop, best of 3: 376 ms per loop

%timeit list(np.ndenumerate(X))
1 loop, best of 3: 570 ms per loop

If you are worried about the performance you could optimise a bit further by looking at the implementation of ndenumerate, which does 2 things, converting to an array and looping. If you know you have an array, you can call the .coords attribute of the flat iterator.

a = X.flat
%timeit list([(a.coords, x) for x in a.flat])
1 loop, best of 3: 305 ms per loop

A little bit naive but this is what I usually remember off the top of my head:

for i in 1 2 3; do
  some commands
done

Very similar to @joe-koberg's answer. His is better especially if you need many repetitions, just harder for me to remember other syntax because in last years I'm not using bash a lot. I mean not for scripting at least.

If you want to detect Chrome's rendering engine (so not specific features in Google Chrome or Chromium), a simple option is:

var isChrome = !!window.chrome;

NOTE: this also returns true for many versions of Edge, Opera, etc that are based on Chrome (thanks @Carrm for pointing this out). Avoiding that is an ongoing battle (see window.opr below) so you should ask yourself if you're trying to detect the rendering engine (used by almost all major modern browsers in 2020) or some other Chrome (or Chromium?) -specific feature.

And you can probably skip !!

Here is a sample package usage, which is quite popular in Laravel community:

{!! Form::select('subdomains[]', $subdomains, null, [
    'id' => 'subdomains',
    'multiple' => true,
    'size' => $subdomains->count(),
    'class' => 'col-12 col-md-4 form-control '.($errors->has('subdomains') ? 'is-invalid' : ''),
]) !!}

In combination with this answer, you can also use this kind of style that is like mobile settings toggler.

HTML

<a href="#" class="toggler">&nbsp;</a>
<a href="#" class="toggler off">&nbsp;</a>
<a href="#" class="toggler">&nbsp;</a>

CSS

a.toggler {
    background: green;
    cursor: pointer;
    border: 2px solid black;
    border-right-width: 15px;
    padding: 0 5px;
    border-radius: 5px;
    text-decoration: none;
    transition: all .5s ease;
}

a.toggler.off {
    background: red;
    border-right-width: 2px;
    border-left-width: 15px;
}

jQuery

$(document).ready(function(){
    $('a.toggler').click(function(){
        $(this).toggleClass('off');
    });
});

Could be much prettier, but gives the idea.
One advantage is that it can be animated with CSS

Copying Will's comment into an answer, because I found it useful:

var string = "this is a string";
var length = 20;
var trimmedString = string.length > length ? 
                    string.substring(0, length - 3) + "..." : 
                    string;

Thanks Will.

And a jsfiddle for anyone who cares https://jsfiddle.net/t354gw7e/ :)

Use NupenGL Nuget package. It is actively updated and works with VS 2013 and 2015, whereas Freeglut Nuget package works with earlier versions of Visual Studio only (as of 10/14/2015).

Also, follow this blog post for easy instructions on working with OpenGL and Glut in VS.

It's easy to copy a folder in a batch file.

 @echo off
 set src_folder = c:\whatever\*.*
 set dst_folder = c:\foo
 xcopy /S/E/U %src_folder% %dst_folder%

And you can add that batch file to your Windows login script pretty easily (assuming you have admin rights on the machine). Just go to the "User Manager" control panel, choose properties for your user, choose profile and set a logon script.

How you get to the user manager control panel depends on which version of Windows you run. But right clicking on My Computer and choosing manage and then choosing Local users and groups works for most versions.

The only sticky bit is "when the folder is updated". This sounds like a folder watcher, which you can't do in a batch file, but you can do pretty easily with .NET.

Yes, you can use the shorthand syntax for if statements.

rate = lambda(t): (200 * exp(-t)) if t > 200 else (400 * exp(-t))

Note that you don't use explicit return statements inlambdas either.

While there is a maven command you can execute to do this, it's easier to just delete the files manually from the repository.

Like this on windows Documents and Settings\your username\.m2 or $HOME/.m2 on Linux

To substantiate @deceze's claim that the default JSON encoding is UTF-8...

From IETF RFC4627:

JSON text SHALL be encoded in Unicode. The default encoding is UTF-8.

Since the first two characters of a JSON text will always be ASCII characters [RFC0020], it is possible to determine whether an octet stream is UTF-8, UTF-16 (BE or LE), or UTF-32 (BE or LE) by looking at the pattern of nulls in the first four octets.

      00 00 00 xx  UTF-32BE
      00 xx 00 xx  UTF-16BE
      xx 00 00 00  UTF-32LE
      xx 00 xx 00  UTF-16LE
      xx xx xx xx  UTF-8

I prefer multiple CSS files during development. Management and debugging is much easier that way. However, I suggest that come deployment time you instead use a CSS minify tool like YUI Compressor which will merge your CSS files into one monolithic file.

I just ran into this (I can't believe it doesn't bind on/off!)

Anyways!

<input type="checkbox" name="checked" />

Will Post a value of "on" or "off".

This WONT bind to a boolean, but you can do this silly workaround!

 public class MyViewModel
 {
     /// <summary>
     /// This is a really dumb hack, because the form post sends "on" / "off"
     /// </summary>                    
     public enum Checkbox
     {
        on = 1,
        off = 0
     }
     public string Name { get; set; }
     public Checkbox Checked { get; set; }
}

I've personally never seen .cc in any project that I've worked on, but in all technicality the compiler won't care.

Who will care is the developers working on your source, so my rule of thumb is to go with what your team is comfortable with. If your "team" is the open source community, go with something very common, of which .cpp seems to be the favourite.

Consider:

Function GetFolder() As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select a Folder"
        .AllowMultiSelect = False
        .InitialFileName = Application.DefaultFilePath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    GetFolder = sItem
    Set fldr = Nothing
End Function

This code was adapted from Ozgrid

    //this will combine all the results into one string
    $string .= '<img src="'.$row['name'].'" />
                <div>'.$row['name'].'</div>
                <div>'.$row['title'].'</div>
                <div>'.$row['description'].'</div>
                <div>'.$row['link'].'</div><br />';

    //or this will add the individual result in an array
 /*
     $yourHtml[] = $row;
*/
    }

then you echo the $tring to the place you want it to be

<div id="place_here">
   <?php echo $string; ?>
   <?php 
     //or
    /*
      echo '<img src="'.$yourHtml[0]['name'].'" />;//change the index, or you just foreach loop it
    */
    ?>
</div>

    Timestamp tsp = new Timestamp(System.currentTimeMillis());
   java.util.Date dateformat = new java.util.Date(tsp.getTime());

Thanks to everyone that posted solutions, I combined multiple approaches to provide some more advanced disabled functionality. Here is a gist, and the code is below.

This provides for multiple levels of defense so that Anchors marked as disable actually behave as such.
Using this approach, you get an anchor that you cannot:
  - click
  - tab to and hit return
  - tabbing to it will move focus to the next focusable element
  - it is aware if the anchor is subsequently enabled


1.  Include this css, as it is the first line of defense.  This assumes the selector you use is 'a.disabled'
    a.disabled {
      pointer-events: none;
      cursor: default;
    }

 2. Next, instantiate this class such as (with optional selector):
    $ ->
      new AnchorDisabler()

Here is the coffescript class:

class AnchorDisabler
  constructor: (selector = 'a.disabled') ->
    $(selector).click(@onClick).keyup(@onKeyup).focus(@onFocus)

  isStillDisabled: (ev) =>
    ### since disabled can be a class or an attribute, and it can be dynamically removed, always recheck on a watched event ###
    target = $(ev.target)
    return true if target.hasClass('disabled')
    return true if target.attr('disabled') is 'disabled'
    return false

  onFocus: (ev) =>
    ### if an attempt is made to focus on a disabled element, just move it along to the next focusable one. ###
    return unless @isStillDisabled(ev)

    focusables = $(':focusable')
    return unless focusables

    current = focusables.index(ev.target)
    next = (if focusables.eq(current + 1).length then focusables.eq(current + 1) else focusables.eq(0))

    next.focus() if next


  onClick: (ev) =>
    # disabled could be dynamically removed
    return unless @isStillDisabled(ev)

    ev.preventDefault()
    return false

  onKeyup: (ev) =>

    # 13 is the js key code for Enter, we are only interested in disabling that so get out fast
    code = ev.keyCode or ev.which
    return unless code is 13

    # disabled could be dynamically removed
    return unless @isStillDisabled(ev)

    ev.preventDefault()
    return false

JavaScript code:

• on mousedown event: set selectedIndex property value to -1
• on change event: handle event

The only drawback is that when the user clicks on the dropdown list, the currently selected item does not appear selected

You can convert it to datetime, and then use DATEADD(DAY, -30, date).

See here.

edit

I suspect many people are finding this question because they want to substract from current date (as is the title of the question, but not what OP intended). The comment of munyul below answers that question more specifically. Since comments are considered ethereal (may be deleted at any given point), I'll repeat it here:

DATEADD(DAY, -30, GETDATE())

The standard way is to use audio/mpeg which is something like this in your PHP header function ...

header('Content-Type: audio/mpeg');

You don't need to convert to Calendar for this, you can just use getTime()/setTime() instead.

getTime(): Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.

setTime(long time) : Sets this Date object to represent a point in time that is time milliseconds after January 1, 1970 00:00:00 GMT. )

There are 1000 milliseconds in a second, and 60 seconds in a minute. Just do the math.

    Date now = new Date();
    Date oneMinuteInFuture = new Date(now.getTime() + 1000L * 60);
    System.out.println(now);
    System.out.println(oneMinuteInFuture);

The L suffix in 1000 signifies that it's a long literal; these calculations usually overflows int easily.

Well if you are using a DataTable at all then rather than comparing two 'DataTables' could you just compare the DataTable that is going to have changes with the original data when it was loaded AKA DataTable.GetChanges Method (DataRowState)

http://htmldog.com/articles/superscript/ Essentially:

position: relative;
bottom: 0.5em;
font-size: 0.8em;

Works well in practice, as far as I can tell.

You can use negative integers with the slicing operator for that. Here's an example using the python CLI interpreter:

>>> a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a[-9:]
[4, 5, 6, 7, 8, 9, 10, 11, 12]

the important line is a[-9:]

Just inserting the line

DateFormatSymbols.getInstance().getMonths()[view.getMonth()] 

will do the trick.

Since things are achanging, at the moment the recommended way of accessing a running container is using nsenter.

You can find more information on this github repository. But in general you can use nsenter like this:

PID=$(docker inspect --format {{.State.Pid}} <container_name_or_ID>)
nsenter --target $PID --mount --uts --ipc --net --pid

or you can use the wrapper docker-enter:

docker-enter <container_name_or_ID>

A nice explanation on the topic can be found on Jérôme Petazzoni's blog entry: Why you don't need to run sshd in your docker containers

How to easily throttle to a specific FPS:

// timestamps are ms passed since document creation.
// lastTimestamp can be initialized to 0, if main loop is executed immediately
var lastTimestamp = 0,
    maxFPS = 30,
    timestep = 1000 / maxFPS; // ms for each frame

function main(timestamp) {
    window.requestAnimationFrame(main);

    // skip if timestep ms hasn't passed since last frame
    if (timestamp - lastTimestamp < timestep) return;

    lastTimestamp = timestamp;

    // draw frame here
}

window.requestAnimationFrame(main);

Play around with scrollIntoViewIfNeeded() ... make sure it's supported by the browser.

my JetBrains IntelliJ IDEA .gitignore configuration, where I need exclude wholde .idea folder except .idea/runConfigurations:

Remove the method, I suspect you might also need to remove it from your Form.Designer.

Otherwise: Application.Exit();

Should work.

That's why the designer is bad for you. :)

I think Tim said it quite well, but let's step back:

A DOM element is an object, a thing in memory. Like most objects in OOP, it has properties. It also, separately, has a map of the attributes defined on the element (usually coming from the markup that the browser read to create the element). Some of the element's properties get their initial values from attributes with the same or similar names (value gets its initial value from the "value" attribute; href gets its initial value from the "href" attribute, but it's not exactly the same value; className from the "class" attribute). Other properties get their initial values in other ways: For instance, the parentNode property gets its value based on what its parent element is; an element always has a style property, whether it has a "style" attribute or not.

Let's consider this anchor in a page at http://example.com/testing.html:

<a href='foo.html' class='test one' name='fooAnchor' id='fooAnchor'>Hi</a>

Some gratuitous ASCII art (and leaving out a lot of stuff):

+-------------------------------------------+
|             HTMLAnchorElement             |
+-------------------------------------------+
| href:       "http://example.com/foo.html" |
| name:       "fooAnchor"                   |
| id:         "fooAnchor"                   |
| className:  "test one"                    |
| attributes:                               |
|    href:  "foo.html"                      |
|    name:  "fooAnchor"                     |
|    id:    "fooAnchor"                     |
|    class: "test one"                      |
+-------------------------------------------+

Note that the properties and attributes are distinct.

Now, although they are distinct, because all of this evolved rather than being designed from the ground up, a number of properties write back to the attribute they derived from if you set them. But not all do, and as you can see from href above, the mapping is not always a straight "pass the value on", sometimes there's interpretation involved.

When I talk about properties being properties of an object, I'm not speaking in the abstract. Here's some non-jQuery code:

var link = document.getElementById('fooAnchor');
alert(link.href);                 // alerts "http://example.com/foo.html"
alert(link.getAttribute("href")); // alerts "foo.html"

(Those values are as per most browsers; there's some variation.)

The link object is a real thing, and you can see there's a real distinction between accessing a property on it, and accessing an attribute.

As Tim said, the vast majority of the time, we want to be working with properties. Partially that's because their values (even their names) tend to be more consistent across browsers. We mostly only want to work with attributes when there is no property related to it (custom attributes), or when we know that for that particular attribute, the attribute and the property are not 1:1 (as with href and "href" above).

The standard properties are laid out in the various DOM specs:

• DOM2 HTML (largely obsolete, see the HTML spec instead)
• DOM2 Core (obsolete)
• DOM3 Core (obsolete)
• DOM4

These specs have excellent indexes and I recommend keeping links to them handy; I use them all the time.

Custom attributes would include, for instance, any data-xyz attributes you might put on elements to provide meta-data to your code (now that that's valid as of HTML5, as long as you stick to the data- prefix). (Recent versions of jQuery give you access to data-xyz elements via the data function, but that function is not just an accessor for data-xyz attributes [it does both more and less than that]; unless you actually need its features, I'd use the attr function to interact with data-xyz attribute.)

The attr function used to have some convoluted logic around getting what they thought you wanted, rather than literally getting the attribute. It conflated the concepts. Moving to prop and attr was meant to de-conflate them. Briefly in v1.6.0 jQuery went too far in that regard, but functionality was quickly added back to attr to handle the common situations where people use attr when technically they should use prop.

The blocksize is usually selected to maximize the "occupancy". Search on CUDA Occupancy for more information. In particular, see the CUDA Occupancy Calculator spreadsheet.

What is the 'best' way? Words like 'most efficient,' 'fastest rendering,' etc. are more specific. Anyway, I am offering an alternative answer that helps me most of the time (whether or not is 'best' is irrelevant).

Alternate answer: Use an iframe.

That is, host the SWF file on the server. If you put the SWF file in the root or public_html folder then the SWF file will be located at www.YourDomain.com/YourFlashFile.swf.

Then, on your index.html or wherever, link the above location to your iframe and it will be displayed around your content wherever you put your iframe. If you can put an iframe there, you can put an SWF file there. Make the iframe dimensions the same as your SWF file. In the example below, the SWF file is 500 by 500.

Pseudo code:

<iframe src="//www.YourDomain.com/YourFlashFile.swf" width="500" height="500"></iframe>

The line of HTML code above will embed your SWF file. No other mess needed. Pros: W3C compliant, page design friendly, no speed issue, minimalist approach.
Cons: White space around your SWF file when launched in a browser.

That is an alternate answer. Whether it is the 'best' answer depends on your project.

You can escape by doubling the quotes

g="abcd """ & a & """"

or write an explicit chr() call

g="abcd " & chr(34) & a & chr(34)

The form tag needs some attributes set:

1. action: The URL that the form data is sent to on submit. Generate it with url_for. It can be omitted if the same URL handles showing the form and processing the data.
2. method="post": Submits the data as form data with the POST method. If not given, or explicitly set to get, the data is submitted in the query string (request.args) with the GET method instead.
3. enctype="multipart/form-data": When the form contains file inputs, it must have this encoding set, otherwise the files will not be uploaded and Flask won't see them.

The input tag needs a name parameter.

Add a view to handle the submitted data, which is in request.form under the same key as the input's name. Any file inputs will be in request.files.

@app.route('/handle_data', methods=['POST'])
def handle_data():
    projectpath = request.form['projectFilepath']
    # your code
    # return a response

Set the form's action to that view's URL using url_for:

<form action="{{ url_for('handle_data') }}" method="post">
    <input type="text" name="projectFilepath">
    <input type="submit">
</form>

For my fellow Swift users, here is the code you will need:

let imageName = "un-child-rights.jpg"
let image = UIImage(named: imageName)
cell.imageView!.image = image

SELECT DATEDIFF(max_date, min_date) as days from my table. This works even if the col max_date and min_date are in string data types.

the split() method takes a regular expression as an argument

OpenSSL provides a passwd command that can encrypt but doesn't decrypt as it only does hashes. You could also download something like aesutil so you can use a capable and well-known symmetric encryption routine.

For example:

#!/bin/sh    
# using aesutil
SALT=$(mkrand 15) # mkrand generates a 15-character random passwd
MYENCPASS="i/b9pkcpQAPy7BzH2JlqHVoJc2mNTBM=" # echo "passwd" | aes -e -b -B -p $SALT 
MYPASS=$(echo "$MYENCPASS" | aes -d -b -p $SALT)

# and usage
serverControl.sh -u admin -p $MYPASS -c shutdown

Hi try this -

 function split(arr, howMany) {
        var newArr = []; start = 0; end = howMany;
        for(var i=1; i<= Math.ceil(arr.length / howMany); i++) {
            newArr.push(arr.slice(start, end));
            start = start + howMany;
            end = end + howMany
        }
        console.log(newArr)
    }
    split([1,2,3,4,55,6,7,8,8,9],3)

This looks for sequences of an uppercase letter followed by one or more lowercase letters. Consecutive uppercase letters will not match, as only one is allowed at a time, and it must be followed by a lowercase one.

The posted answers using multiline strings and multiple bash scripts did not work for me.

• Long multiline strings are hard to maintain.
• Separate bash scripts do not maintain local variables.

Here is a functional way to ssh and run multiple commands while keeping local context.

LOCAL_VARIABLE=test

run_remote() {
    echo "$LOCAL_VARIABLE"
    ls some_folder; 
    ./someaction.sh 'some params'
    ./some_other_action 'other params'
}

ssh otherhost "$(set); run_remote"

For python2/3, Using below code snippet we can activate virtual env.

activate_this = "/home/<--path-->/<--virtual env name -->/bin/activate_this.py" #for ubuntu
activate_this = "D:\<-- path -->\<--virtual env name -->\Scripts\\activate_this.py" #for windows
with open(activate_this) as f:
    code = compile(f.read(), activate_this, 'exec')
    exec(code, dict(__file__=activate_this))

The shortest expression is

curl 'http://…' | jq length

    private void button1_Click(object sender, EventArgs e)
    {
        Form2 frm = new Form2(this);
        frm.Show();
    }

Form2:

public partial class Form2 : Form
{
    Form opener;

    public Form2(Form parentForm)
    {
        InitializeComponent();
        opener = parentForm;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        opener.Close();
        this.Close();
    }
}

Fall through approach is the best one i feel.

case text1:
case text4: {

See there is no difference if you use basic hide method. But jquery provides various hide method which give effects to the element. Refer below link for detailed explanation: Effects for Hide in Jquery

You can also use backtrace Ruby gem (I'm the author):

require 'backtrace'
begin
  # do something dangerous
rescue StandardError => e
  puts Backtrace.new(e)
end

Do whatever you want to do after the file loads successfully.just after the completion of your file processing set the value of file control to blank string.so the .change() will always be called even the file name changes or not. like for example you can do this thing and worked for me like charm

   $('#myFile').change(function () {
       LoadFile("myFile");//function to do processing of file.
       $('#myFile').val('');// set the value to empty of myfile control.
    });

You override $today in the if statement.

if($dd<10){$dd='0'+dd} if($mm<10){$mm='0'+$mm} $today = $dd+'/'+$mm+'/'+$yyyy;

It is then not a Date() object anymore - hence the error.

It depends on what makes the most sense for your case.

Does it make sense to return null, e.g. "no such user exists"?

Or does it make sense to create a default user? This makes the most sense when you can safely assume that if a user DOESN'T exist, the calling code intends for one to exist when they ask for it.

Or does it make sense to throw an exception (a la "FileNotFound") if the calling code is demanding a user with an invalid ID?

However - from a separation of concerns/SRP standpoint, the first two are more correct. And technically the first is the most correct (but only by a hair) - GetUserById should only be responsible for one thing - getting the user. Handling its own "user does not exist" case by returning something else could be a violation of SRP. Separating into a different check - bool DoesUserExist(id) would be appropriate if you do choose to throw an exception.

Based on extensive comments below: if this is an API-level design question, this method could be analogous to "OpenFile" or "ReadEntireFile". We are "opening" a user from some repository and hydrating the object from the resultant data. An exception could be appropriate in this case. It might not be, but it could be.

All approaches are acceptable - it just depends, based on the larger context of the API/application.

append the revision using an "@" character:

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

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

I had the same error and none of your solutions helped. I think my problem was simply the name that I had chosen for the project. I had named my project 'interface' which when I got the parse error it said that it couldn't load:

Line 1: <%@ Application Codebehind="Global.asax.cs" Inherits="@interface.MvcApplication" Language="C#" %>

Where there was an '@' sign for some reason. I am guessing the word 'interface' is reserved for something else and it added the @ symbol but that obviously broke something. I deleted the project and made a new one with a different name with no problems.

May be helpful for late comers.

As simple as placing something along those lines within your HTML assuming your server is set-up to execute PHP in files with the HTML extension.

WebElement select = driver.findElement(By.id("gender"));
List<WebElement> options = select.findElements(By.tagName("option"));
for (WebElement option : options) {
   if("Germany".equals(option.getText()))
       option.click();   
}

Remove the unwanted , sign in the function. you will get the solution.

The answers are commonly found in Java books.

1. cloning: If you don't override clone method, the default behavior is shallow copy. If your objects have only primitive member variables, it's totally ok. But in a typeless language with another object as member variables, it's a headache.

2. serialization/deserialization

$new_object = unserialize(serialize($your_object))

This achieves deep copy with a heavy cost depending on the complexity of the object.

You can use this:

SELECT CONVERT(VARCHAR(5), GETDATE(),8)  

Output:

08:24

Since version 3.2 :

def toSigned(n, byte_count): 
  return int.from_bytes(n.to_bytes(byte_count, 'little'), 'little', signed=True)

output :

In swift 4 : by overriding method

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        let storyboard = UIStoryboard(name : "Main", bundle: nil)
        let next vc = storyboard.instantiateViewController(withIdentifier: "nextvcIdentifier") as! NextViewController

       self.navigationController?.pushViewController(prayerVC, animated: true)
}

If using the following HTML:

<button id="submit-button"></button>

Style can be applied through JS using the style object available on an HTMLElement.

To set height and width to 200px of the above example button, this would be the JS:

var myButton = document.getElementById('submit-button');
myButton.style.height = '200px';
myButton.style.width= '200px';

I believe with this method, you are not directly writing CSS (inline or external), but using JavaScript to programmatically alter CSS Declarations.

I had installed python3 but my python in /usr/bin/python was still the old 2.7 version

This worked (<pkg> was pyserial in my case):

python3 -m pip install <pkg>

Something like that should be what you need

private void button1_Click(object sender, RoutedEventArgs e)
{
    // Create OpenFileDialog 
    Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();



    // Set filter for file extension and default file extension 
    dlg.DefaultExt = ".png";
    dlg.Filter = "JPEG Files (*.jpeg)|*.jpeg|PNG Files (*.png)|*.png|JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif"; 


    // Display OpenFileDialog by calling ShowDialog method 
    Nullable<bool> result = dlg.ShowDialog();


    // Get the selected file name and display in a TextBox 
    if (result == true)
    {
        // Open document 
        string filename = dlg.FileName;
        textBox1.Text = filename;
    }
}

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

Why don't you use the libraries that come with the .NET framework: http://msdn.microsoft.com/en-us/library/ms229718.aspx?

We don't recommend that you use the FtpWebRequest class for new development. For more information and alternatives to FtpWebRequest, see WebRequest shouldn't be used on GitHub. (https://docs.microsoft.com/en-us/dotnet/api/system.net.ftpwebrequest?view=netframework-4.7.2)

The 'WebRequest shouldn't be used' page in turn points to this question as the definitive list of libraries!

Answering to myself. From the RequireJS website:

//THIS WILL FAIL
define(['require'], function (require) {
    var namedModule = require('name');
});

This fails because requirejs needs to be sure to load and execute all dependencies before calling the factory function above. [...] So, either do not pass in the dependency array, or if using the dependency array, list all the dependencies in it.

My solution:

// Modules configuration (modules that will be used as Jade helpers)
define(function () {
    return {
        'moment':   'path/to/moment',
        'filesize': 'path/to/filesize',
        '_':        'path/to/lodash',
        '_s':       'path/to/underscore.string'
    };
});

The loader:

define(['jade', 'lodash', 'config'], function (Jade, _, Config) {
    var deps;

    // Dynamic require
    require(_.values(Config), function () {
        deps = _.object(_.keys(Config), arguments);

        // Use deps...
    });
});

$('#selector').delay(5000).fadeOut('slow');

From my experience its always better to avoid using FKs in Database Critical Applications. I would not disagree with guys here who say FKs is a good practice but its not practical where the database is huge and has huge CRUD operations/sec. I can share without naming ... one of the biggest investment bank of doesn't have a single FK in databases. These constrains are handled by programmers while creating applications involving DB. The basic reason is when ever a new CRUD is done it has to effect multiple tables and verify for each inserts/updates, though this won't be a big issue for queries affecting single rows but it does create a huge latency when you deal with batch processing which any big bank has to do as daily tasks.

Its better to avoid FKs but its risk has to be handled by programmers.

I'm in the process of setting up a CI build server on a Linux box for a legacy system started in 2000. There is a section that generates a PDF that contains non-UTF8 characters. We are in the final steps of a release, so I cannot replace the characters giving me grief, yet for Dilbertesque reasons, I cannot wait a week to solve this issue after the release. Fortunately, the "javac" command in Ant has an "encoding" parameter.

 <javac destdir="${classes.dir}" classpathref="production-classpath" debug="on"
     includeantruntime="false" source="${java.level}" target="${java.level}"

     encoding="iso-8859-1">

     <src path="${production.dir}" />
 </javac>

Following @Daniel's comment and thanks to @Tom's answer, I found out that Git bash was indeed using the PATH but not the latest paths I recently installed. To work around this problem, I added a file in my home (windows) directory named:

.bashrc

and the content as follow:

PATH=$PATH:/c/Go/bin

because I was installing Go and this path contained the executable go.exe Now Git bash was able to recognize the command:

go

Perhaps just a system reboot would have been enough in my case, but I'm happy that this solution work in any case.

If you want to carry on using CSS3 selectors but need to support older browsers I would suggest using a polyfill such as Selectivizr.js

Procedures:

• Go to your CPanel
• Select PHP version
• Click on the link Switch to PHP options
• Edit your configuration
• don't forget to click save

you didn't use time() function that returns the current time measured in the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT). use like this:

$date = strtotime(time());
$date = strtotime("+7 day", $date);
echo date('M d, Y', $date);

N joy...

For those from 2018 and beyond, using npm version 5 or later: edit your package-lock.json: remove the library from "requires" section and add it under "dependencies".

For example, you want deglob package to use glob package version 3.2.11 instead of its current one. You open package-lock.json and see:

"deglob": {
  "version": "2.1.0",
  "resolved": "https://registry.npmjs.org/deglob/-/deglob-2.1.0.tgz",
  "integrity": "sha1-TUSr4W7zLHebSXK9FBqAMlApoUo=",
  "requires": {
    "find-root": "1.1.0",
    "glob": "7.1.2",
    "ignore": "3.3.5",
    "pkg-config": "1.1.1",
    "run-parallel": "1.1.6",
    "uniq": "1.0.1"
  }
},

Remove "glob": "7.1.2", from "requires", add "dependencies" with proper version:

"deglob": {
  "version": "2.1.0",
  "resolved": "https://registry.npmjs.org/deglob/-/deglob-2.1.0.tgz",
  "integrity": "sha1-TUSr4W7zLHebSXK9FBqAMlApoUo=",
  "requires": {
    "find-root": "1.1.0",
    "ignore": "3.3.5",
    "pkg-config": "1.1.1",
    "run-parallel": "1.1.6",
    "uniq": "1.0.1"
  },
  "dependencies": {
    "glob": {
      "version": "3.2.11"
    }
  }
},

Now remove your node_modules folder, run npm install and it will add missing parts to the "dependencies" section.

Seems like the cleanest way in this example is to:

• Use a RelativeLayout
• Position the 2 adjacent views one below the other
• Align the FAB to the parent right/end and add a right/end margin
• Align the FAB to the bottom of the header view and add a negative margin, half the size of the FAB including shadow

Example adapted from shamanland implementation, use whatever FAB you wish. Assume FAB is 64dp high including shadow:

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

    <View
        android:id="@+id/header"
        android:layout_width="match_parent"
        android:layout_height="120dp"
    />

    <View
        android:id="@+id/body"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/header"
    />

    <fully.qualified.name.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignBottom="@id/header"
        android:layout_marginBottom="-32dp"
        android:layout_marginRight="20dp"
    />

</RelativeLayout>

You can use a Dictionary to keep track of the keys and values.

For instance...

dictOfStuff = {} ##Make a Dictionary

x = "Buffalo" ##OR it can equal the input of something, up to you.

dictOfStuff[x] = 4 ##Get the dict spot that has the same key ("name") as what X is equal to. In this case "Buffalo". and set it to 4. Or you can set it to  what ever you like

print(dictOfStuff[x]) ##print out the value of the spot in the dict that same key ("name") as the dictionary.

A dictionary is very similar to a real life dictionary. You have a word and you have a definition. You can look up the word and get the definition. So in this case, you have the word "Buffalo" and it's definition is 4. It can work with any other word and definition. Just make sure you put them into the dictionary first.

A little late to the party, but I think regular expressions are not the right tool for the job.

The problem is that you'll come across edge cases which would add extranous complexity to the regular expression. @est mentioned an example line:

for (int i = 0; i < 10; doSomethingTo("("));

This string literal contains an (unbalanced!) parenthesis, which breaks the logic. Apparently, you must ignore contents of string literals. In order to do this, you must take the double quotes into account. But string literals itself can contain double quotes. For instance, try this:

for (int i = 0; i < 10; doSomethingTo("\"(\\"));

If you address this using regular expressions, it'll add even more complexity to your pattern.

I think you are better off parsing the language. You could, for instance, use a language recognition tool like ANTLR. ANTLR is a parser generator tool, which can also generate a parser in Python. You must provide a grammar defining the target language, in your case C++. There are already numerous grammars for many languages out there, so you can just grab the C++ grammar.

Then you can easily walk the parser tree, searching for empty statements as while or for loop body.

I want to use R rather than pre-processing the data as it makes it easier when the data are revised. Following Shane's suggestion of using gsub, I think this is about as neat as I can do:

x <- read.csv("file.csv",header=TRUE,colClasses="character")
col2cvt <- 15:41
x[,col2cvt] <- lapply(x[,col2cvt],function(x){as.numeric(gsub(",", "", x))})

For anyone who looks at this today after 2 years, Visual Studio 2019 (Community edition as well) shows the references

Go to Solution properties ? Common Properties ? Startup Project and select Multiple startup projects.

You can use routerLink in the following manner,

<input type="button" value="Add Bulk Enquiry" [routerLink]="['../addBulkEnquiry']" class="btn">

or use <button [routerLink]="['./url']"> in your case, for more info you could read the entire stacktrace on github https://github.com/angular/angular/issues/9471

the other methods are also correct but they create a dependency on the component file.

Hope your concern is resolved.

File->Project Structure->Project pane->"Android plugin version".

Make sure you don't confuse the Gradle version with the Android plugin version. The former is the build system itself, the latter is the plugin to the build system that knows how to build Android projects

Using promises for Node versions greater than 8.0.0:

const {promisify} = require('util');
const fs = require('fs');
const {join} = require('path');
const mv = promisify(fs.rename);

const moveThem = async () => {
  // Move file ./bar/foo.js to ./baz/qux.js
  const original = join(__dirname, 'bar/foo.js');
  const target = join(__dirname, 'baz/qux.js'); 
  await mv(original, target);
}

moveThem();

This is over simplifying it, but Express.js is to Node.js what Ruby on Rails or Sinatra is to Ruby.

Express 3.x is a light-weight web application framework to help organize your web application into an MVC architecture on the server side. You can use a variety of choices for your templating language (like EJS, Jade, and Dust.js).

You can then use a database like MongoDB with Mongoose (for modeling) to provide a backend for your Node.js application. Express.js basically helps you manage everything, from routes, to handling requests and views.

Redis is a key/value store -- commonly used for sessions and caching in Node.js applications. You can do a lot more with it, but that's what I'm using it for. I use MongoDB for more complex relationships, like line-item <-> order <-> user relationships. There are modules (most notably connect-redis) that will work with Express.js. You will need to install the Redis database on your server.

Here is a link to the Express 3.x guide: https://expressjs.com/en/3x/api.html

I had the same error:
"Syntax error, unrecognized expression: // "
It is known bug at JQuery, so i needed to think on workaround solution,
What I did is:
I changed "script" tag to "div"
and added at angular this code
and the error is gone...

app.run(['$templateCache', function($templateCache) {
    var url = "survey-input.html";
    content = angular.element(document.getElementById(url)).html()
    $templateCache.put(url, content);
}]);

Know the master key yourself. Don't hard code it.

Use py-bcrypt (bcrypt), powerful hashing technique to generate a password yourself.

Basically you can do this (an idea...)

import bcrypt
from getpass import getpass
master_secret_key = getpass('tell me the master secret key you are going to use')
salt = bcrypt.gensalt()
combo_password = raw_password + salt + master_secret_key
hashed_password = bcrypt.hashpw(combo_password, salt)

save salt and hashed password somewhere so whenever you need to use the password, you are reading the encrypted password, and test against the raw password you are entering again.

This is basically how login should work these days.

There are two things to remember here. One is to add the -PassThru argument and two is to add the -Wait argument. You need to add the wait argument because of this defect: http://connect.microsoft.com/PowerShell/feedback/details/520554/start-process-does-not-return-exitcode-property

-PassThru [<SwitchParameter>]
    Returns a process object for each process that the cmdlet started. By d
    efault, this cmdlet does not generate any output.

Once you do this a process object is passed back and you can look at the ExitCode property of that object. Here is an example:

$process = start-process ping.exe -windowstyle Hidden -ArgumentList "-n 1 -w 127.0.0.1" -PassThru -Wait

You can use, which will be triggered when the window resizes.

$( window ).bind("resize", function(){
    // Change the width of the div
    $("#yourdiv").width( 600 );
});

If you want a DIV width as percentage of the screen, just use CSS width : 80%;.

The '.env' file should be in the root directory of your node js server file (server.js or for me).

If you placed the '.env' file at the root of your project, it won't work. My mistake was that I have the server.js file nested in a folder named 'controller'.

So I had to fix it by placing the .env file in the same directory as the server.js file.

You will have to open the file in one way or another if you want to access the data within it. Obviously, one way is to open it in your Excel application instance, e.g.:-

(untested code)

Dim wbk As Workbook
Set wbk = Workbooks.Open("C:\myworkbook.xls")

' now you can manipulate the data in the workbook anyway you want, e.g. '

Dim x As Variant
x = wbk.Worksheets("Sheet1").Range("A6").Value

Call wbk.Worksheets("Sheet2").Range("A1:G100").Copy
Call ThisWorbook.Worksheets("Target").Range("A1").PasteSpecial(xlPasteValues)
Application.CutCopyMode = False

' etc '

Call wbk.Close(False)

Another way to do it would be to use the Excel ADODB provider to open a connection to the file and then use SQL to select data from the sheet you want, but since you are anyway working from within Excel I don't believe there is any reason to do this rather than just open the workbook. Note that there are optional parameters for the Workbooks.Open() method to open the workbook as read-only, etc.

I sometimes do a mysqldump and pipe the output into another mysql command to import it into a different database.

mysqldump --add-drop-table -u wordpress -p wordpress | mysql -u wordpress -p wordpress_backup

items[node.ind] = items[node.ind]._replace(v=node.v)

(Note: Don't be discouraged to use this solution because of the leading underscore in the function _replace. Specifically for namedtuple some functions have leading underscore which is not for indicating they are meant to be "private")

Anything wrong with:

@Test
void itWorks() {
    // stuff
}

@Test
void itWorksRepeatably() {
    for (int i = 0; i < 10; i++) {
        itWorks();
    }
}

Unlike the case where you are testing each of an array of values, you don't particularly care which run failed.

It seems pretty hard to have a regex that does exactly what you want (i.e. accept only the cases that you need and reject all others and return some groups for the three components). I've give it a try and come up with this:

^(\*|(\d+(\.(\d+(\.(\d+|\*))?|\*))?))$

IMO (I've not tested extensively) this should work fine as a validator for the input, but the problem is that this regex doesn't offer a way of retrieving the components. For that you still have to do a split on period.

This solution is not all-in-one, but most times in programming it doesn't need to. Of course this depends on other restrictions that you might have in your code.

A primitive type cannot be null. So the solution is replace primitive type with primitive wrapper class in your tableName.java file. Such as:

@Column(nullable=true, name="client_os_id")
private Integer client_os_id;

public int getClient_os_id() {
    return client_os_id;
}

public void setClient_os_id(int clientOsId) {
    client_os_id = clientOsId;
}

reference http://en.wikipedia.org/wiki/Primitive_wrapper_class to find wrapper class of a primivite type.

If you are using gcc, you can use the GNU-extension a specifier to have scanf() allocate memory for you to hold the input:

int main()
{
  char *str = NULL;

  scanf ("%as", &str);
  if (str) {
      printf("\"%s\"\n", str);
      free(str);
  }
  return 0;
}

Edit: As Jonathan pointed out, you should consult the scanf man pages as the specifier might be different (%m) and you might need to enable certain defines when compiling.

Your values object is obviously an Object[] containing a String[] containing the values.

String[] stringValues = (String[])values[0];

This is one more option: go to Windows > Preference > Java > Editor > Content Assit. Look in "Auto Activation" zone, sure that "Enable auto activation" is checked and add more charactor (like "abcd....yz, default is ".") to auto show content assist menu as your typing.

You have three option here for removing duplicate item in your List:

1. Use a a custom equality comparer and then use Distinct(new DistinctItemComparer()) as @Christian Hayter mentioned.

2. Use GroupBy, but please note in GroupBy you should Group by all of the columns because if you just group by Id it doesn't remove duplicate items always. For example consider the following example:

   List<Item> a = new List<Item>
   {
       new Item {Id = 1, Name = "Item1", Code = "IT00001", Price = 100},
       new Item {Id = 2, Name = "Item2", Code = "IT00002", Price = 200},
       new Item {Id = 3, Name = "Item3", Code = "IT00003", Price = 150},
       new Item {Id = 1, Name = "Item1", Code = "IT00001", Price = 100},
       new Item {Id = 3, Name = "Item3", Code = "IT00003", Price = 150},
       new Item {Id = 3, Name = "Item3", Code = "IT00004", Price = 250}
   };
   var distinctItems = a.GroupBy(x => x.Id).Select(y => y.First());
   

   The result for this grouping will be:

   {Id = 1, Name = "Item1", Code = "IT00001", Price = 100}
   {Id = 2, Name = "Item2", Code = "IT00002", Price = 200}
   {Id = 3, Name = "Item3", Code = "IT00003", Price = 150}
   

   Which is incorrect because it considers {Id = 3, Name = "Item3", Code = "IT00004", Price = 250} as duplicate. So the correct query would be:

   var distinctItems = a.GroupBy(c => new { c.Id , c.Name , c.Code , c.Price})
                        .Select(c => c.First()).ToList();
   

   3.Override Equal and GetHashCode in item class:

   public class Item
   {
       public int Id { get; set; }
       public string Name { get; set; }
       public string Code { get; set; }
       public int Price { get; set; }
   
       public override bool Equals(object obj)
       {
           if (!(obj is Item))
               return false;
           Item p = (Item)obj;
           return (p.Id == Id && p.Name == Name && p.Code == Code && p.Price == Price);
       }
       public override int GetHashCode()
       {
           return String.Format("{0}|{1}|{2}|{3}", Id, Name, Code, Price).GetHashCode();
       }
   }
   

   Then you can use it like this:

   var distinctItems = a.Distinct();
   

Android 4.4 (KitKat) and higher devices have a shell utility for recording the Android device screen. Connect a device in developer/debug mode running KitKat with the adb utility over USB and then type the following:

adb pull /sdcard/movie.mp4

Screen recording is limited to a maximum of 3 minutes.

If you have two facets hospital and room but want to rename just one, you can use:

facet_grid( hospital ~ room, labeller = labeller(hospital = as_labeller(hospital_names)))

For renaming two facets using the vector-based approach (as in naught101's answer), you can do:

facet_grid( hospital ~ room, labeller = labeller(hospital = as_labeller(hospital_names),
                                                 room = as_labeller(room_names)))

Rahul's answer gives me an error: You seem to be trying to send a WhatsApp message to a phone number that is not registered with WhatsApp..., even though I'm sending it to a registered WhatsApp number.

This, however works:

<li><a href="intent:0123456789#Intent;scheme=smsto;package=com.whatsapp;action=android.intent.action.SENDTO;end"><i class="fa fa-whatsapp"></i>+237 655 421 621</li>

This should work for you:

let example = $('#example').DataTable({
    columnDefs: [{
        orderable: false,
        className: 'select-checkbox',
        targets: 0
    }],
    select: {
        style: 'os',
        selector: 'td:first-child'
    },
    order: [
        [1, 'asc']
    ]
});
example.on("click", "th.select-checkbox", function() {
    if ($("th.select-checkbox").hasClass("selected")) {
        example.rows().deselect();
        $("th.select-checkbox").removeClass("selected");
    } else {
        example.rows().select();
        $("th.select-checkbox").addClass("selected");
    }
}).on("select deselect", function() {
    ("Some selection or deselection going on")
    if (example.rows({
            selected: true
        }).count() !== example.rows().count()) {
        $("th.select-checkbox").removeClass("selected");
    } else {
        $("th.select-checkbox").addClass("selected");
    }
});

I've added to the CSS though:

table.dataTable tr th.select-checkbox.selected::after {
    content: "?";
    margin-top: -11px;
    margin-left: -4px;
    text-align: center;
    text-shadow: rgb(176, 190, 217) 1px 1px, rgb(176, 190, 217) -1px -1px, rgb(176, 190, 217) 1px -1px, rgb(176, 190, 217) -1px 1px;
}

Working JSFiddle, hope that helps.

Check if db name do not have "_" or "-" that helps in my case

We can use relative path instead of absolute path:

$assetPath: '~src/assets/images/';
$logo-img: '#{$assetPath}logo.png';
@mixin logo {
  background-image: url(#{$logo-img});
}

.logo {
    max-width: 65px;
    @include logo;
 }

One of The Shortest method i found for single value while i was searching for myself, is just passing single string and setting string as model in view like this.

In your Partial calling side

@Html.Partial("ParitalAction", "String data to pass to partial")

And then binding the model with Partial View like this

@model string

and the using its value in Partial View like this

@Model

You can also play with other datatypes like array, int or more complex data types like IDictionary or something else.

Hope it helps,

Try this:

df[df['column_name'] == ''].index

and for NaNs you can try:

pd.isna(df['column_name'])

Make your life easier with dotenv-webpack. Simply install it npm install dotenv-webpack --save-dev, then create an .env file in your application's root (remember to add this to .gitignore before you git push). Open this file, and set some environmental variables there, like for example:

ENV_VAR_1=1234
ENV_VAR_2=abcd
ENV_VAR_3=1234abcd

Now, in your webpack config add:

const Dotenv = require('dotenv-webpack');
const webpackConfig = {
  node: { global: true, fs: 'empty' }, // Fix: "Uncaught ReferenceError: global is not defined", and "Can't resolve 'fs'".
  output: {
    libraryTarget: 'umd' // Fix: "Uncaught ReferenceError: exports is not defined".
  },
  plugins: [new Dotenv()]
};
module.exports = webpackConfig; // Export all custom Webpack configs.

Only const Dotenv = require('dotenv-webpack');, plugins: [new Dotenv()], and of course module.exports = webpackConfig; // Export all custom Webpack configs. are required. However, in some scenarios you might get some errors. For these you have the solution as well implying how you can fix certain error.

Now, wherever you want you can simply use process.env.ENV_VAR_1, process.env.ENV_VAR_2, process.env.ENV_VAR_3 in your application.

It depends on what you want to test:

• for a string, you can use If strName = vbNullString or IF strName = "" or Len(strName) = 0 (last one being supposedly faster)
• for an object, you can use If myObject is Nothing
• for a recordset field, you could use If isnull(rs!myField)
• for an Excel cell, you could use If range("B3") = "" or IsEmpty(myRange)

Extended discussion available here (for Access, but most of it works for Excel as well).

You need text() or html() for label not val() The function should not be called for label instead it is used to get values of input like text or checkbox etc.

Change

value = $("#telefon").val(); 

To

value = $("#telefon").text(); 

To Make it work in Eclipse Juno - I had to do some additional steps.

In General -> Editors -> File Association

1. Select "*.class" and mark "Class File Editor" as default
2. Select "*.class without source" -> Add -> "Class File Editor" -> Make it as default
3. Restart eclipse

This particular error has very little to do with the actual error. Here is my similar experience and the solution...

I had a table that I use in my statement with |database-name|.login composite name. I thought this wouldn't be a problem. It was the problem indeed. Enclosing it inside square brackets solved my problem ([|database-name|].[login]). So, the problem is MySQL preserved words (other way around)... make sure your columns too are not failing to this type of error scenario...

In this example cafec_param is a base class (parent class) and abc is a child class. abc calls the AWC method in the base class.

class cafec_param:

    def __init__(self,precip,pe,awc,nmonths):

        self.precip = precip
        self.pe = pe
        self.awc = awc
        self.nmonths = nmonths

    def AWC(self):

        if self.awc<254:
            Ss = self.awc
            Su = 0
            self.Ss=Ss
        else:
            Ss = 254; Su = self.awc-254
            self.Ss=Ss + Su   
        AWC = Ss + Su
        return self.Ss


    def test(self):
        return self.Ss
        #return self.Ss*4

class abc(cafec_param):
    def rr(self):
        return self.AWC()


ee=cafec_param('re',34,56,2)
dd=abc('re',34,56,2)
print(dd.rr())
print(ee.AWC())
print(ee.test())

I have edited the code from one of the example here to use jquery. It's still not 100% jquery though. Any thoughts on the two different versions, like what are the pros and cons of each?

function column_sort() {
    getCellValue = (tr, idx) => $(tr).find('td').eq( idx ).text();

    comparer = (idx, asc) => (a, b) => ((v1, v2) => 
        v1 !== '' && v2 !== '' && !isNaN(v1) && !isNaN(v2) ? v1 - v2 : v1.toString().localeCompare(v2)
        )(getCellValue(asc ? a : b, idx), getCellValue(asc ? b : a, idx));
    
    table = $(this).closest('table')[0];
    tbody = $(table).find('tbody')[0];

    elm = $(this)[0];
    children = elm.parentNode.children;
    Array.from(tbody.querySelectorAll('tr')).sort( comparer(
        Array.from(children).indexOf(elm), table.asc = !table.asc))
        .forEach(tr => tbody.appendChild(tr) );
}

table.find('thead th').on('click', column_sort);

There is no difference.

COUNT(1) is basically just counting a constant value 1 column for each row. As other users here have said, it's the same as COUNT(0) or COUNT(42). Any non-NULL value will suffice.

The Oracle optimizer did apparently use to have bugs in it, which caused the count to be affected by which column you picked and whether it was in an index, so the COUNT(1) convention came into being.

I was looking for some information regarding reloads on pages retrieved with POST requests, such as after submitting a method="post" form.

To reload the page keeping the POST data, use:

window.location.reload();

To reload the page discarding the POST data (perform a GET request), use:

window.location.href = window.location.href;

Hopefully this can help others looking for the same information.

Just another way to do this:

Please careful with $.inArray if you want to use it. I just found out that the $.inArray is only works with "Array", not with String. That's why this function will not working in IE8!

The jQuery API make confusion

The $.inArray() method is similar to JavaScript's native .indexOf() method in that it returns -1 when it doesn't find a match. If the first element within the array matches value, $.inArray() returns 0

--> They shouldn't say it "Similar". Since indexOf support "String" also!

I encountered the same problem when I tried to install curl in my 32 bit win 7 machine. As answered by Buravchik it is indeed dependency of SSL and installing openssl fixed it. Just a point to take care is that while installing openssl you will get a prompt to ask where do you wish to put the dependent DLLS. Make sure to put it in windows system directory as other programs like curl and wget will also be needing it.

HotSwap support: the object-oriented architecture of the Java HotSpot VM enables advanced features such as on-the-fly class redefinition, or "HotSwap". This feature provides the ability to substitute modified code in a running application through the debugger APIs. HotSwap adds functionality to the Java Platform Debugger Architecture, enabling a class to be updated during execution while under the control of a debugger. It also allows profiling operations to be performed by hotswapping in versions of methods in which profiling code has been inserted.

For the moment, this only allows for newly compiled method body to be redeployed without restarting the application. All you have to do is to run it with a debugger. I tried it in Eclipse and it works splendidly.

Also, as Emmanuel Bourg mentioned in his answer (JEP 159), there is hope to have support for the addition of supertypes and the addition and removal of methods and fields.

To setup GruntJS build here is the steps:

1. Make sure you have setup your package.json or setup new one:

   npm init
   

2. Install Grunt CLI as global:

   npm install -g grunt-cli
   

3. Install Grunt in your local project:

   npm install grunt --save-dev
   

4. Install any Grunt Module you may need in your build process. Just for sake of this sample I will add Concat module for combining files together:

   npm install grunt-contrib-concat --save-dev
   

5. Now you need to setup your Gruntfile.js which will describe your build process. For this sample I just combine two JS files file1.js and file2.js in the js folder and generate app.js:

   module.exports = function(grunt) {
   
       // Project configuration.
       grunt.initConfig({
           concat: {
               "options": { "separator": ";" },
               "build": {
                   "src": ["js/file1.js", "js/file2.js"],
                   "dest": "js/app.js"
               }
           }
       });
   
       // Load required modules
       grunt.loadNpmTasks('grunt-contrib-concat');
   
       // Task definitions
       grunt.registerTask('default', ['concat']);
   };
   

6. Now you'll be ready to run your build process by following command:

   grunt
   

I hope this give you an idea how to work with GruntJS build.

NOTE:

You can use grunt-init for creating Gruntfile.js if you want wizard-based creation instead of raw coding for step 5.

To do so, please follow these steps:

npm install -g grunt-init
git clone https://github.com/gruntjs/grunt-init-gruntfile.git ~/.grunt-init/gruntfile
grunt-init gruntfile

For Windows users: If you are using cmd.exe you need to change ~/.grunt-init/gruntfile to %USERPROFILE%\.grunt-init\. PowerShell will recognize the ~ correctly.

git add -A
git diff HEAD

Generate patch if required, and then:

It also important to make sure that the web server sends the file with Content-Disposition = inline. this might not be the case if you are reading the file yourself and send it's content to the browser:

In addition to Gusev Slava's answer, you might want to use groupby's groups:

{key: df.loc[value] for key, value in df.groupby("name").groups.items()}

This will yield a dictionary with the keys you have grouped by, pointing to the corresponding partitions. The advantage is that the keys are maintained and don't vanish in the list index.

A UIImageView is derived from a UIView which is derived from UIResponder so it's ready to handle touch events. You'll want to provide the touchesBegan, touchesMoved, and touchesEnded methods and they'll get called if the user taps the image. If all you want is a tap event, it's easier to just use a custom button with the image set as the button image. But if you want finer-grain control over taps, moves, etc. this is the way to go.

You'll also want to look at a few more things:

• Override canBecomeFirstResponder and return YES to indicate that the view can become the focus of touch events (the default is NO).

• Set the userInteractionEnabled property to YES. The default for UIViews is YES, but for UIImageViews is NO so you have to explicitly turn it on.

• If you want to respond to multi-touch events (i.e. pinch, zoom, etc) you'll want to set multipleTouchEnabled to YES.

JKALAVIS solution is good, however I would add an improvement to use shlex instead of SHELL=TRUE. below im grepping out Query times

#!/bin/python
import subprocess
import shlex

cmd = "dig @8.8.4.4 +notcp www.google.com|grep 'Query'"
ps = subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE,stderr=subprocess.STDOUT)
output = ps.communicate()[0]
print(output)

I don't know of any way to access a mobile phone's camera from the web browser without some additional mechanism (i.e. Flash or some type of container that allows access to the hardware API)

For the latter have a look at PhoneGap: http://docs.phonegap.com/phonegap_camera_camera.md.html

With this you should be able to access the camera at least on iOS and Android-based devices.

There is no any method getCurrentItem() in viewpager.i already checked the API

Jquery or Javascipt doesn't provide a built-in method to achieve this.

CSS test transform (text-transform:capitalize;) doesn't really capitalize the string's data but shows a capitalized rendering on the screen.

If you are looking for a more legit way of achieving this in the data level using plain vanillaJS, use this solution =>

var capitalizeString = function (word) {    
    word = word.toLowerCase();
    if (word.indexOf(" ") != -1) { // passed param contains 1 + words
        word = word.replace(/\s/g, "--");
        var result = $.camelCase("-" + word);
        return result.replace(/-/g, " ");
    } else {
    return $.camelCase("-" + word);
    }
}

There are two ways, depending on your original timestamp:

mktime() and timegm()

http://docs.python.org/library/time.html

There is more stable function, also gets rid of string folding.

// Add to C++ source
bool string_equal (const char* arg0, const char* arg1)
{
    /*
     * This function wraps string comparison with string pointers
     * (and also works around 'string folding', as I said).
     * Converts pointers to std::string
     * for make use of string equality operator (==).
     * Parameters use 'const' for prevent possible object corruption.
     */
    std::string var0 = (std::string) arg0;
    std::string var1 = (std::string) arg1;
    if (var0 == var1)
    {
        return true;
    }
    else
    {
        return false;
    }
}

And add declaration to header

// Parameters use 'const' for prevent possible object corruption.
bool string_equal (const char* arg0, const char* arg1);

For usage, just place an 'string_equal' call as condition of if (or ternary) statement/block.

if (string_equal (var1, "dev"))
{
    // It is equal, do what needed here.
}
else
{
    // It is not equal, do what needed here (optional).
}

I know it is late but I just want to share on what I have done for this. I'm not allowed to add another table or trigger so I need to generate it in a single query upon insert. For your case, can you try this query.

CREATE TABLE YOURTABLE(
IDNUMBER VARCHAR(7) NOT NULL PRIMARY KEY,
ENAME VARCHAR(30) not null
);

Perform a select and use this select query and save to the parameter @IDNUMBER

(SELECT IFNULL
     (CONCAT('LHPL',LPAD(
       (SUBSTRING_INDEX
        (MAX(`IDNUMBER`), 'LHPL',-1) + 1), 5, '0')), 'LHPL001')
    AS 'IDNUMBER' FROM YOURTABLE ORDER BY `IDNUMBER` ASC)

And then Insert query will be :

INSERT INTO YOURTABLE(IDNUMBER, ENAME) VALUES 
(@IDNUMBER, 'EMPLOYEE NAME');

The result will be the same as the other answer but the difference is, you will not need to create another table or trigger. I hope that I can help someone that have a same case as mine.

final Map<String, String> mss1 = new ProcessBuilder().environment();
mss1.entrySet()
        .stream()
        //depending on how you want to join K and V use different delimiter
        .map(entry -> 
        String.join(":", entry.getKey(),entry.getValue()))
        .forEach(System.out::println);

<?php

    // Get absolute path
    $path = getcwd(); // /home/user/public_html/test/test.php.   

    $path = substr($path, 0, strpos($path, "public_html"));

    $root = $path . "public_html/";

    echo $root; // This will output /home/user/public_html/

Check out this Unicode code converter. For example, enter 0x2009, where 2009 is the Unicode number for thin space, in the "0x... notation" field, and click Convert. The hexadecimal number E2 80 89 (3 bytes) appears in the "UTF-8 code units" field.

You could use a StringReader and convert the reader to an input stream using the solution in this other stackoverflow post.

If you are using Mac and running Catalina and Installed Mongodb via Homebrew what you have to do to start is just type this command and you are good to go.

This tidbit is useful for displaying elapsed time to varying degrees of granularity.

I personally think that questions of efficiency are practically meaningless here, so long as something grossly inefficient isn't being done. Premature optimization is the root of quite a bit of evil. This is fast enough that it'll never be your choke point.

intervals = (
    ('weeks', 604800),  # 60 * 60 * 24 * 7
    ('days', 86400),    # 60 * 60 * 24
    ('hours', 3600),    # 60 * 60
    ('minutes', 60),
    ('seconds', 1),
    )

def display_time(seconds, granularity=2):
    result = []

    for name, count in intervals:
        value = seconds // count
        if value:
            seconds -= value * count
            if value == 1:
                name = name.rstrip('s')
            result.append("{} {}".format(value, name))
    return ', '.join(result[:granularity])

..and this provides decent output:

In [52]: display_time(1934815)
Out[52]: '3 weeks, 1 day'

In [53]: display_time(1934815, 4)
Out[53]: '3 weeks, 1 day, 9 hours, 26 minutes'

Normally, that is not an error per se; it is a warning that the first file it found that matches the -lPI-Http argument to the compiler/linker is not valid. The error occurs when no other library can be found with the right content.

So, you need to look to see whether /dvlpmnt/libPI-Http.a is a library of 32-bit object files or of 64-bit object files - it will likely be 64-bit if you are compiling with the -m32 option. Then you need to establish whether there is an alternative libPI-Http.a or libPI-Http.so file somewhere else that is 32-bit. If so, ensure that the directory that contains it is listed in a -L/some/where argument to the linker. If not, then you will need to obtain or build a 32-bit version of the library from somewhere.

To establish what is in that library, you may need to do:

mkdir junk
cd junk
ar x /dvlpmnt/libPI-Http.a
file *.o
cd ..
rm -fr junk

The 'file' step tells you what type of object files are in the archive. The rest just makes sure you don't make a mess that can't be easily cleaned up.

For (2), Guava provides exactly what you want as Int.asList(). There is an equivalent for each primitive type in the associated class, e.g., Booleans for boolean, etc.

    int[] arr={1,2,3};
    for(Integer i : Ints.asList(arr)) {
      System.out.println(i);
    }

Below code worked for me:

<input #fileInput type="file" id="avatar" accept="application/pdf,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document" />

application/pdf means .pdf
application/msword means .doc
application/vnd.openxmlformats-officedocument.wordprocessingml.document means .docx

Query to achieve your requirment

SELECT id,GROUP_CONCAT(text SEPARATOR ' ') AS text FROM table_name group by id;

Honestly, I like the other answers. Easy and no need to get into JS. But I noticed that you were asking about jQuery. So for the sake of completeness, in jQuery if you return false with the .click() handler, it will negate the default action of the widget.

See here for an example (and more goodies, too). Here's the documentation, too.

in a nutshell, with your sample code, do this:

<script type="text/javascript">
    $('button[type!=submit]').click(function(){
        // code to cancel changes
        return false;
    });
</script>

<a href="index.html"><button>Cancel changes</button></a>
<button type="submit">Submit</button>

As an added benefit, with this, you can get rid of the anchor tag and just use the button.

Most people use Hungarian notation in a wrong way and are getting wrong results.

Read this excellent article by Joel Spolsky: Making Wrong Code Look Wrong.

In short, Hungarian Notation where you prefix your variable names with their type (string) (Systems Hungarian) is bad because it's useless.

Hungarian Notation as it was intended by its author where you prefix the variable name with its kind (using Joel's example: safe string or unsafe string), so called Apps Hungarian has its uses and is still valuable.

This seems to be an issue when using bootstrap unless you are rendering the form by {{ form(form)}}. In addition, the issues seems to only occur on input type="hidden". If you inspect the page the with the form, you'll find that the hidden input is not part of the markup at all or it's being rendered but not submitted for some reason. As suggested above, adding {{form_rest(form)}} or wrapping the input like below should do the trick.

<div class="form-group">
    <input type="hidden" name="_csrf_token" value="{{ csrf_token('authenticate') }}">
</div>

I personally favor HSQLDB, but mostly because it was the first I tried.

H2 is said to be faster and provides a nicer GUI frontend (which is generic and works with any JDBC driver, by the way).

At least HSQLDB, H2 and Derby provide server modes which is great for development, because you can access the DB with your application and some tool at the same time (which embedded mode usually doesn't allow).

Here is how I am

getting current location and showing on Map in Swift 2.0

Make sure you have added CoreLocation and MapKit framework to your project (This doesn't required with XCode 7.2.1)

import Foundation
import CoreLocation
import MapKit

class DiscoverViewController : UIViewController, CLLocationManagerDelegate {

    @IBOutlet weak var map: MKMapView!
    var locationManager: CLLocationManager!

    override func viewDidLoad()
    {
        super.viewDidLoad()

        if (CLLocationManager.locationServicesEnabled())
        {
            locationManager = CLLocationManager()
            locationManager.delegate = self
            locationManager.desiredAccuracy = kCLLocationAccuracyBest
            locationManager.requestAlwaysAuthorization()
            locationManager.startUpdatingLocation()
        }
    }

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
    {

        let location = locations.last! as CLLocation

        let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
        let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))

        self.map.setRegion(region, animated: true)
    }
}

Here is the result screen

Collections.emptyMap()

$("#myImg").one("load",function(){
  //do something, like getting image width/height
}).each(function(){
  if(this.complete) $(this).trigger("load");
});

The way to set JFrame to full-screen, is to set MAXIMIZED_BOTH option which stands for MAXIMIZED_VERT | MAXIMIZED_HORIZ, which respectively set the frame to maximize vertically and horizontally

package Example;
import java.awt.GraphicsConfiguration;
import javax.swing.JFrame;
import javax.swing.JButton;

public class JFrameExample
{
    static JFrame frame;
    static GraphicsConfiguration gc;
    public static void main(String[] args)
    {
        frame = new JFrame(gc);
        frame.setTitle("Full Screen Example");
        frame.setExtendedState(MAXIMIZED_BOTH);

        JButton button = new JButton("exit");
        b.addActionListener(new ActionListener(){@Override
        public void actionPerformed(ActionEvent arg0){
            JFrameExample.frame.dispose();
            System.exit(0);
        }});

        frame.add(button);
        frame.setVisible(true);
    }
}
