How to sort in-place using the merge sort algorithm?
...ations. According to my test, it's faster than the standard version, which allocates extra spaces in every recursion. But it's slower than the optimized version, which doubles the original array in advance and uses it for further merging.

What does 'require: false' in Gemfile mean?
...equire these additional gems in every process". I don't think that's true. Allocating objects takes work, and the GC has to run through all of them each time, so more = slower, according to confreaks.com/videos/2668-gogaruco2013-measuring-ruby

Resolve build errors due to circular dependency amongst classes
...ember that the .cc and not the .h is the unit of compilation), you need to allocate space for object A. So, well, how much space then? Enough to store B! What's the size of B then? Enough to store A! Oops.
Clearly a circular reference that you must break.
You can break it by allowing the compiler ...

...terminated. So the pool can shrink if threads remain too much idle.
If all allocated threads are occupied while a new task comes in, then it creates a new thread, as offering a new task to a SynchronousQueue always fails when there is no one on the other end to accept it!
When should I use one...
When to use inline function and when not to use it?
...iron reason to avoid inlining a function. The implementation is obliged to allocate a single static object for each function static whether or not the function is declared inline or not. Classes are still extensible if they have inline constructors and virtual destructors. And empty brace destructor...
