How to test multiple variables against a value?
... If you can arrange for the most likely case to be first in the tuple, the win is even bigger: (my test: timeit.timeit('0 in {seq}'.format(seq=tuple(range(9, -1, -1)))))

How are virtual functions and vtable implemented?
...ect(*(void **)x,8,PROT_READ|PROT_WRITE|PROT_EXEC);
// Or VirtualProtect on win32; this part's very OS-specific
(*(int (***)(A *)x)[0] = f3;
// Now C::f1() returns 0 (remember we made x into a C above)
// so x->f1() and z->f1() both return 0
The latter is rather likely to make virus-checkers ...
Hashset vs Treeset
...tation of bubble sort (O(N^2) avg/worst) for 10 elements. Bubble sort will win every time. The point is algorithms classes teach everyone to think about approximations using time-complexity but in the real world the constant factors MATTER frequently.

Use of Initializers vs Constructors in Java
...initialization and still have the static variable be final. This is a big win.
I find "if (someStaticVar == null) // do stuff" to be messy and error prone. If it is initialized statically and declared final, then you avoid the possibility of it being null.
However, I'm confused when you say:

Any reason to clean up unused imports in Java, other than reducing clutter?
...list interface.
In Eclipse you can always use a shortcut (depends on OS - Win: Ctrl + SHIFT + O and Mac: COMMAND + SHIFT + O) to organize the imports. Eclipse then cleans up the import section removes all the stale imports etc. If you are needing a imported thing again eclipse will add them automat...
