Looping through a filter with arguments in Javascript
24/4/2016 7:43 am by compcons in Web Development

Im trying to filter the zeroth arguments of the function using the other arguments of the function. The loop and filter functions seem to be working but the problem seems to be that the loop doesn't loop all the way through. I'm not exactly sure what is going on in this case. Here is the code:

function destroyer(arr) {

    var args = Array.from(arguments);

So I am using a UIPickerView as the first responder of a UITextField. I set this as shows:

var myPickerView = UIPickerView()

virtual function call within a class member function
24/4/2016 7:43 am by Ernie in Web Development

I understand the basic concept of virtual function and vtable, but in the following example, I don't understand why c.A(); prints out

parent A

but without the virtual keyword for Parent::func(), it prints out

parent A

Would you let me know the reason in detail? It would be great to explain with vtable, memory (he

24/4/2016 7:43 am by Brandan in Web Development

I am aware there is at least a dozen other questions here on this issue, but I've tried all of them and I seem to have applied all the techniques they suggest, so please if you would kindly take a look at my code here and tell me if I am missing something. I am getting a 404 everytime I refresh a page other than the root.

p.s. If I understand correctly, my root domain is not reloading

Printing whole numbers with {#} in C#?
24/4/2016 7:43 am by Mark W in Web Development

I'm sorry if this is a duplicate but I haven't found anything relevant to it.

So, how can I print 0 for the numbers having a whole square root with the following code?

for (n = 1.0; n <= 10; n++) {
        Console.WriteLine ("Fractional Part : {0 :#.####}", (Math.Sqrt(n) -
(int) Math.Sqrt(n)));

Current O/P:

Wait until any key is held in AppleScript?
24/4/2016 7:43 am by Andrew Forbes in Web Development

I have an AppleScript background script which generates hotkey events by System Events. So I need stop the script before generate keystroke and wait until user releases all keys (otherwise effect will be unpredictable).

How can I get this done? I don't need exactly AppleScript solution. It does not matter, I can just call external Python/Bash/ObjC/Swift. Anything, but I onl

MergExt mergDataGridScroller how to temporary disable scrolling
24/4/2016 7:43 am by Mansur in Web Development

I am using the mergDataGridScroller in a LiveCode desktop and mobile app and it works fine. But on mobile, when I show a group on top of the card (on top of the mergDataGridScroller and not related to it) to present a choice to the user for something else, the mergDataGridScroller still react to the mouse/touch moving. Is there a way to temporary disable the mergDataGridScroller ? Thanks

Semantics of abstract traits in Scala
31/3/2016 3:42 pm by ghost recon88 in Web Development

I am wondering what the semantics of using the abstract keyword in combination with a trait is.

If the trait does not define any abstract methods, the abstract keyword does not prevent me from creating an instance:

scala> abstract trait T
defined trait T

scala> new T{}
res0: java.lang.Object with T = $anon$1@12cd927d

Compass placing or position in a map view post iOS6
31/3/2016 3:42 pm by Jammy in Web Development

Does anyone know of a way to change the placing of the compass in MKMapview?

I'm talking about the compass that shows up in the upper right corner of the map when it's rotated.

I'm making it so you can see the map blurred underneath the navigation bar, which means the frame's y origin will be underneath the nav-bar. The problem is that when the map is rotated, it automatically

Is there a float input type in HTML(5)?
31/3/2016 3:42 pm by Chris Tattum in Web Development

According to http://simon.html5.org/html-elements, the "number" input type's "value attribute, if specified and not empty, must have a value that is a valid floating point number."

Yet it is simply (in Chrome.latest, anyway), an "updown" control with integers, not floats:
