Is it possible to use chapters in videos for the iPhone in an application?
For example:
I have a 3 minutes video to play. I have chapter 1 starting at 0s, chapter 2 at 50s, chapter 3 at 95s.
Can I start plating the video at 50s (chapter 2) until the end? Can I make it play just the chapter 2 from 50s to 95s? |

C# question (.net 3.5). I have a class, ImageData, that has a field ushort[,] pixels. I am dealing with proprietary image formats.

[ViewVC][1] provides a nice web interface to CVS (or SVN) and is reasonably easy to setup. It does not provide the same functionality as fisheye, however. I haven't tried the integration w/ a SQL DB backend though, I believe that will add some fisheye-like capabilities.

I think it depends on the individual or group. Almost all shops have some exposure to one of these concepts.

It depends on your architecture. If you're all on the same tier, then you can go without the wrapper, though I'd probably pass an interface that View implements to Controller. Functionally, and from a coupling perspective, the interface approach and the wrapper approach are equivalent.

Object initializers does in no way replace constructors. The constructor defines the contract that you have to adhere to in order to create a instance of a class.
The main motivation for object initializers in the C# language is to support [Anonymous Types](http://msdn.microsoft.com/en-us/library/bb397696.aspx).

We've also seen some issues with VS built-in server regarding some third-party controls which put their scripts at the \aspnet_client folder.

Unless you're doing rocket-science, a decimal is WAAAY overkill. And although it might give you more precise positions, it will not necessarily give you more precise (eg) velocities, since it is a fixed-point datatype and therefore is limited to a much smaller range than a float or double.

Bracketing your one-liner if statements has the considerable sane-making advantage of protecting you from headaches if, at some later point, you (or other coders maintaining or altering your code) need to add statements to some part of that conditional block. |
No matter what you do, without additional constraints on the input values, you cannot do better than O(n^2), simply because you have to iterate through all pairs of numbers. The iteration will dominate sorting (which you can do in O(n log n) or faster). |

One solution is to just store all numbers as rational numbers in the first place. There are libraries for rational number arithmetic (eg [GMP][1]). If using an OO language you may be able to just use a rational number class library to replace your number class.
