  • CADisplayLink stops updating when UIScrollView scrolled

    - by Tricky
    Title is quite self explanatory, but I have some animation being done in a loop triggered by CADisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill.... Anyway to cancel this behaviour?

  • Need help with some functions and variables

    - by Doug
    function createXMLHTTP() { xmlhttp = =new XMLHttpRequest(); return xmlhttp; } I'm trying to create 3 instances of this, but it all has the same variable name which is xmlhttp. How can I dynamically create different variable names? I'm not sure if that's the right way to ask the question. I want to create like xmlhttp1, xmlhttp2, xmlhttp3, so then I can reference each one.

  • Python Split usage

    - by Chris M
    I'm cocking this up and it should be really simple but the value of sortdate is none (note im only doing this because converting a string to a date in Python is a bugger). DateToPass = str(self.request.get('startdate')) mybreak.startdate = DateToPass faf = DateToPass.split('-') sortdate = str(faf[2] + faf[1] + faf[0]) That should work? but its just being stored as null though the datetopass is being stored fine.

  • Facebook Connect: Redirect to FB login page instead of popup

    - by AyKarsi
    I'm just starting of to get Facebook connect to work. One thing that really bugs me, is that when I click the FB login button, it opens up a popup. I would much more prefer to have the user redirected to FB, where he can login and be sent back to my site. (Just like openid login works here at SO) I can't find anything in the docs, although I have the feeling I'm not looking in the right place: http://developers.facebook.com/docs/reference/javascript/fb.api/

  • About presenter pattern in rails. is a better way to do it?

    - by Totty
    I have in my model: def presenter @presenter ||= ProfilePresenter.new(self) @presenter end The ProfilePresenter is a class that has methods like, get_link(), get_img_url(size), get_sex(), get_relationship_status() and other methods that have not to do with the model, not even with the controller but is used multiple times in the view. So now i use them by doing this: Profile.presenter.get_link # or Profile.presenter.get_img_url('thumb') # returns the path of the image. is not used to make a db query

  • [C++] Is it possible to roll a significantly faster version of sqrt

    - by John
    In an app I'm profiling, I found that in some scenarios this functions are able to take over 10% of total execution time. I've seen discussion over the years of faster sqrt implementations using sneaky floating-point trickery, but I don't know if such things are outdated on modern CPUs. MSVC++ 2008 compiler is being used, for reference... though I'd assume sqrt is not going to add much overhead though.
