Fast and responsive interactive charts/graphs: SVG, Canvas, other?
...ins and the element inspector—that it is often premature optimization to start with Canvas. Combining Canvas with SVG, as in the Facebook IPO visualization you linked, is a flexible way to retain most of these conveniences while still eking out the best performance. I also used this technique in C...
Why are const parameters not allowed in C#?
...etty shallow argument you're making here. The callee is also free to just start writing random memory locations with 0xDEADBEEF. But both would be very bad programming, and caught early and poignantly by any modern compiler. In the future when writing answers, please don't confuse what's technica...

Thus, if you are conscientious, you will need:
Stream encoding detection algorithm.
Dynamic / runtime stream filter definition algorithm (because ...

Should accessing SharedPreferences be done off the UI Thread?
...erences anyway during onCreate(), that loading time is stalling your app's start-up unnecessarily, so it's generally better to have something like a FutureTask<SharedPreferences> subclass that kicks off a new thread to .set() the FutureTask subclasses's value. Then just lookup your FutureTask...
