Why does Java's Arrays.sort method use two different sorting algorithms for different types?
...dy sorted array, it may not stay unchanged.
Since primitive types have no identity (there is no way to distinguish two ints with the same value), this does not matter for them. But for reference types, it could cause problems for some applications. Therefore, a stable merge sort is used for those.

How to use JavaScript source maps (.map files)?
... file, and will allow you to see the original version of the code. If you didn't have the sourcemap, then any error would seem cryptic at best.
Same for CSS files. Once you take a SASS or LESS file and compile it to CSS, it looks nothing like its original form. If you enable sourcemaps, then you can...

JKS is the most common if you stay within the Java world. PKCS#12 isn't Java-s...

Is it possible to make a type only movable and not copyable?
...he type doesn't have a Drop implementation.
To answer the question you didn't ask... "what's up with moves and copy?":
Firstly I'll define two different "copies":

...for running glue code or trivial scripts.
PyPy and CPython behavior is not identical in all respects, especially when it comes to "implementation details" (behavior that is not specified by the language but is still important at a practical level).
