Why should I use the keyword “final” on a method parameter in Java?
...ly possible to completely ignore this programming practice and still write excellent code. One person's programming practice does not make it everyone's practice. Stand by it all you will, I choose to write it different anyway. Does that make me a bad programmer, or my code bad code?

Why can't we have static method in a (non-static) inner class?
...
@gustafc, I think that was an excellent explanation. But as Lawrence points out, it's only a failure because of the reference to foo, which isn't static. But what if I wanted to write public static double sinDeg(double theta) { ... } an an inner math util...
Why shouldn't I use PyPy over CPython if PyPy is 6.3 times faster?
...bly intelligent group of people and have a managed to help CPython perform excellent in such a scenario. Here's a shameless blog plug: http://www.hydrogen18.com/blog/unpickling-buffers.html .

How much faster is C++ than C#?
...rth mentioning for the sake of completeness that C#'s runtime optimizer is excellent, and is able to perform certain dynamic optimizations at runtime that are simply not available to C++ with its compile-time (static) optimizer. Even with this, the advantage is still typically deeply in the native ...
Sending files using POST with HttpURLConnection

Excellent, just misses one thing: that responseStreamReader should be closed in the finally of the try/catch. This way: try{ ALL YOUR CODE } catch (IOException e) { e.printStackTrace(); } finally { ...
What are the big improvements between guava and apache equivalent libraries?
...learning curve to take full advantage of it. As mentioned, the Javadoc is excellent, but some longer source code case studies would be helpful.
If you're in an environment requiring Java 1.3 or 1.4, you're out of luck.
