  • Huge framerate difference between Test and Publish movie in Flash?

    - by Glacius
    Simply put, I am making a flash midi player. I am using ENTER_FRAME for my timings. I set the framerate to 100 to ensure that the timing of each note in milliseconds is accurate. When I test the movie with CTRL + ENTER it works fine. When I publish it and open it in a browser (tested both IE and Chrome), it suddenly plays back a lot slower. I don't think it's a performance issue, since the code is very simple. If this slowdown is consistent then I can perhaps work with it so that the playback speed will be correct. Do browsers make the framerate slower or do they implement a framerate cap of some sort? What is going on?

  • What is the difference between type.__getattribute__ and object.__getattribute__?

    - by Neil G
    Given: In [37]: class A: ....: f = 1 ....: In [38]: class B(A): ....: pass ....: In [39]: getattr(B, 'f') Out[39]: 1 Okay, that either calls super or crawls the mro? In [40]: getattr(A, 'f') Out[40]: 1 This is expected. In [41]: object.__getattribute__(A, 'f') Out[41]: 1 In [42]: object.__getattribute__(B, 'f') --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) <ipython-input-42-de76df798d1d> in <module>() ----> 1 object.__getattribute__(B, 'f') AttributeError: 'type' object has no attribute 'f' What is getattribute not doing that getattr does? In [43]: type.__getattribute__(B, 'f') Out[43]: 1 What?! type.__getattribute__ calls super but object's version doesn't? In [44]: type.__getattribute__(A, 'f') Out[44]: 1

  • How to handle date difference between client and server?

    - by daydreamer
    I have an API which looks like /summary/yyyy/mm Which returns the summary of their data for the year and month requested. One of the things it returns the number of days left if this is current year and month. For example: days_left: 9 for 2013 and 10 and current date on server is 21 Oct 2013 How I calculate remaining days? This is implemented in python as def current_financial_month_details(self): time_from, time_to = self \ .get_start_end_time_current_financial_month() today = datetime.today() from_time = datetime(year=today.year, month=today.month, day=today.day) return { 'time_from': time_from, 'time_to': time_to, 'remaining_days': (time_to - from_time).days } The problem? The server is in east coast and the client(me with browser) is on pacific time zone When its 9PM PST the time changes in east coast, so if I run hit /summary/2013/10 and if it is Oct 21 2013 for me on PST, the date has already changed on EST, so days_left: 8 which is incorrect on client end. right? How do I handle this situation?

  • Is there an difference between transient properties defined in the data model, or in the custom subc

    - by mystify
    I was reading that setting the value of a transient property always results in marking the managed object as "dirty". However, what I don't get is this: If I make a subclass of NSManagedObject and use some extra properties which I don't need to be persistet, how does Core Data know about them and how can it mark the object as dirty when I access these? Again, they're not defined in the data model, so Core Data has no really good hint that they are there. Or does Core Data use some kind of introspection to analyze my custom class and figure out what properties I have in there?

  • In elisp is there a difference between the regex [\\]documentclass and \\documentclass?

    - by mcheema
    I was playing around with the rx function for generating regular expressions from sexps in ELISP but couldn't figure out how to generate the regular expression "\\documentclass" for use in org-export-latex-classes: (rx "\\documentclass") (rx "\\" "documentclass") (rx (char "\\") "documentclass") Which when evaluated give respectively the following outputs: "\\\\documentclass" "\\\\documentclass" "[\\]documentclass" Is "\\documentclass" equivalent to "[\\]documentclass"?---I think it is, but am not sure. Can I generate the former using rx? Edit: Whilst the question was valid I realize my motivation was not; because org-export-latex-classes use strings not regular expressions.

  • Is there a difference between `==` and `is` in python?

    - by Bernard
    My Google-fu has failed me. In Python, are these: n = 5 # Test one. if n == 5: print 'Yay!' # Test two. if n is 5: print 'Yay!' two tests for equality equivalent (ha!)? Does this hold true for objects where you would be comparing instances (a list say)? Okay, so this kind of answers my question: l = list() l.append(1) if l == [1]: print 'Yay!' # Holds true, but... if l is [1]: print 'Yay!' # Doesn't. So == tests value where is tests to see if they are the same object?

  • Is there any difference between var name = function() {} & function name() {} in Javascript?

    - by Fletcher Moore
    Suppose we are inside a function and not in the global namespace. function someGlobalFunction() { var utilFunction1 = function() { } function utilFunction2 () { } utilFunction1(); utilFunction2(); } Are these synonymous? And do these functions completely cease to exist when someGlobalFunction returns? Should I prefer one or the other for readability or some other reason?

  • What's the difference between the box-model bug and the new box-sizing CSS?

    - by RKS
    In days (long past for some, and still present for others) the box-model bug was a bane to their existence. The idea that an element's width included the margin, border, and padding was blasphemous and an abomination to their senses. So we got away from it after thousands of internet blogs about the box-model hack. Now we get box-sizing, which will, wait for it, allow you to specify that a width contains the border, the margin, and the padding. We plaster a trendy new name for it, "CSS3 Flexbox," and now it's the freedom designers have been looking for. For those logical people who saw the box-model bug as not the bug and the W3C as the actual bug, this comes as a surprise. A reintroduction of this so-called bug and now we call it an enhancement? So can someone explain why this is different? I am honestly confused about this.

  • What is the difference between an object's scope and it's context in javascript?

    - by DKinzer
    In the vernacular, scope and context have a lot in common. Which is why I get confused when I read references to both, such as in the quote below from an article on closures: Scope refers to where variables and functions are accessible, and in what context it is being executed. (@robertnyman) As far as I can tell, context is just a reference to an object. Can someone please explain what exactly is context, as used, for instance, in the jQuery syntax, $(selector, context). And is an object's scope the same at it's context?

  • What's the difference between initializing this structure with these strategies?

    - by mystify
    // the malloc style, which returns a pointer: struct Cat *newCat = malloc(sizeof(struct Cat)); // no malloc...but isn't it actually the same thing? uses memory as well, or not? struct Cat cat = {520.0f, 680.0f, NULL}; Basically, I can get a initialized structure in these two ways. My guess is: It's the same thing, but when I use malloc I also have to free() that. In the second case I don't have to think about memory, because I don't call malloc. Maybe. When should I use the malloc style, and when the other?

  • In gzip libary, what's the difference between 'uncompress' and 'gzopen' ?

    - by Sol
    There are some functions to decompress in zlib library(zlib version 1.2.3) I want to decompress my source zip(.gz) file using 'uncompress' function. It is now working(error code -3) but gzopen is. It is still not working when I input payload pointer(passing gzip header) to 'uncompress' . So the question is "What's the valid arguments for uncompress function?" and If it needs different format, how can I make it? Google doesn't helpful this time :(
