• JSONP & jQuery Chunking

  - by Tom

  Hi Guys, I am wanting to utilize JSONP for a project with x-domain scripting but little concerned with the 2048 character limit in IE. Does JSONP support "chunking" automatically if character size exceeds 2048 ? If yes, does anyone have any examples they can share ? Thx

• Pretty Pixel-level Picture Painting, Programatically

  - by dreeves

  My mac laptop has 1,024,000 pixels. What's the simplest way to turn my display completely black and go nuts with writing little programs to twiddle pixels to my heart's delight? To make it more concrete, say I wanted to implement the Chaos Game to draw a Sierpinski triangle, at the pixel level, with nothing else on the screen. What are ways to do that?

• Is there a better way to declare an empty, typed matrix in MATLAB?

  - by Arthur Ward

  Is there a way to "declare" a variable with a particular user-defined type in MATLAB? zeros() only works for built-in numeric types. The only solution I've come up with involves using repmat() to duplicate a dummy object zero times: arr = repmat(myClass(), [1 0]) Without declaring variables this way, any code which does "arr(end+1) = myClass()" has to include a special case for the default empty matrix which is of type double. Have I missed something a little more sensible?

• Best programming based games

  - by Matt Sheppard

  Back when I was at school, I remember tinkering with a Mac game where you programmed little robots in a sort of pseudo-assembler language which could then battle each other. They could move themselves around the arena, look for opponents in different directions, and fire some sort of weapon. Pretty basic stuff, but I remember it quite fondly, even if I can't remember the name. Are there any good modern day equivalents?

  - by chefgon

  For an example of what I'm looking for, hit the Home button while you're composing a message in the Gmail app. A little message will pop up at the bottom of the screen for a moment that says "Message saved as Draft."

• Cross platform GUI Programming with D

  - by Adam Hawes

  I want to start programming with D. I have a simple application in mind that needs a GUI but I want to make sure it's portable to Linux/Windows/Mac equally well and with minimal (no) change for each platform. wxD is looking like the contender of choice because I know the wx toolkit already. I see fltk4d as a contender and a (unfinished) wrapper around Qt. Are there any other truly cross platform GUI toolkits for D that will go where I want with little effort and what would the the toolkit of choice for people here?

  I'm trying to shrink a Windows 7 XP Mode VHD file with VhdResizer with little success. When I select my VHD file, it says "VhdExpand only supports fixed and dynamic VHD files". My XP Mode VHDs are dynamic files. Does anyone have any idea why it is failing? Failing that, does anyone have a process that I can use to shrink my XP mode VHD files on Windows 7 (64 bit)?

• iPhone: keep text looking good after scale transform applied?

  - by Greg Maletic

  I'm applying a scale transform to a UIView that draws a number. (The number is literally being drawn with drawInRect; no UILabel in sight.) The scale transform makes the view smaller by quite a bit...say, 80% smaller. The resulting number looks a little "chunky". Is there a way that I can keep my text looking nice and anti-aliased, the way it's supposed to look? Thanks.

  When a user clicks on the little red "x" a.k.a. the form close button on the form command bar, what even is activated besides FormClosed() I know FormClosing() is called, but I cannot really stop the form from closing after my code is run. I want to be able to show a messagebox that asks if the user wants to exit the form or not. Obviously if they click no, I want the form to stay open, how would I do this?
