iPhone App Icons - Exact Radius?
...ightly larger, sometimes (sigh) slightly smaller. Using a square icon will free you from this burden, and you will be sure to have an always up-to-date and good looking icon for your app.
This approach is valid for each icon size (iPhone/iPod/iPad/retina), and also for the iTunes artwork. I followed...
Why was “Avoid Enums Where You Only Need Ints” removed from Android's performance tips?
...ass does of course mean that your app contains an extra class, so it's not free, but we have to assume that a developer is only adding enums where they're useful. The only really bad use I've seen of enums was in some harmony code where they really wanted ints (for bitmasks and the like) and the "en...

Full disclosure
This library is a free open source wrapper library, and I am the author of said library. I make no money off of this but have found it immensely useful over the years and am sure anyone who is still using the HttpWebRequest / HttpWebResponse ...
Difference between numpy.array shape (R, 1) and (R,)
...─┘
and so:
>>> d[10,0]
10
A dimension of length 1 is "free" (in some sense), so there's nothing stopping you from going to town:
>>> e = a.reshape((1, 2, 1, 6, 1))
giving an array indexed like this:
i= 0 0 0 0 0 0 0 0 0 0 0 0
j= 0 0...

How do the likely/unlikely macros in the Linux kernel work and what is their benefit?
... the prediction is correct it means that the jump instruction is basically free and will take zero cycles. On the other hand if the prediction is wrong, then it means the processor pipeline needs to be flushed and it can cost several cycles. So long as the prediction is correct most of the time, thi...
When should I write the keyword 'inline' for a function/method?
...
Yes. The inline is only a hint to the compiler, and it is free to ignore you. These days the compiler probably knows better than the programmer which functions are best to inline.

How to optimize for-comprehensions and loops in Scala?
...y. You should note note that the use of return in isEvenlyDivisible is not free. The use of return inside the for, forces the scala compiler to generate a non-local return (i.e. to return outside it's function).
This is done through the use of an exception to exit the loop. The same happens if you ...
When is a C++ destructor called?
...o replace an object with another object of the same type but don't want to free memory just to allocate it again. You can destroy the old object in place and construct a new one in place. (However, generally this is a bad idea.)
