Here's an untested implementation of takeWhile on a Spliterator:

Delete all files in directory (but not directory) - one liner solution
...iles from ABC (sub-directories are untouched):
Arrays.stream(new File("C:/test/ABC/").listFiles()).forEach(File::delete);
This deletes only files from ABC (and sub-directories):
Files.walk(Paths.get("C:/test/ABC/"))
.filter(Files::isRegularFile)

You might be wondering why none of these methods bother checking to see whether or not the store has reached the maximum size. I'll get to that i...

Why is Go so slow (compared to Java)?
...ons in JIT-compiled Java) starts to get tricky.
FWIW, my own very trivial test with Go when I was taking a look at it (a loop of integer addition, basically), gccgo produced code towards the fast end of the range between gcc -O0 and gcc -O2 for equivalent C. Go isn't inherently slow, but the compil...
C# DateTime.Now precision
...n into some unexpected behavior with DateTime.UtcNow while doing some unit tests. It appears that when you call DateTime.Now/UtcNow in rapid succession, it seems to give you back the same value for a longer-than-expected interval of time, rather than capturing more precise millisecond increments.
