I want to dive a little into WordPress codebase but modern PHP is quite a different language from what I’ve learned – albeit a little – way ago, so long ago that WordPress didn’t even existed then. Beside reading the obvious official documentation, I’ve discovered that the almighty O’Really seems not to have a recent book on PHP, or a book about recent PHP either. As books from Packt publishing quite often turns out to be “quite shallow”, I’ve been looking for info the good old way, namely IRC channels. They told me these little gems:
Well, they really look the right documentation for me.
As the author clearly stated in a comment, this is more of a proof-of-concept for learning ceph, not for a real deploy as it’s not meant to be cheaper per GB, but cheaper for initial cost: a “3 figure cost of entry way to begin learning ceph”.
Even today (year 2017) an x86 based solution will have a minimum cost much higher while giving higher performances (129€ just for a single CPU board plus case without memory and storage)
