ext4 noacl mount option

Brace your mtabs/fstabs/proc/self/mounts!
The error line makes it pretty clear:

EXT4-fs: Mount option "noacl" will be removed by 3.5
Contact if you think we should keep it.

Hm, is that only happens to me that the same kernel built with gcc 4.7.0
is 11 MiBs bigger than the one built with gcc 4.6.0...

Josuttis on C++11

Nicolai Josuttis talks about C++ and why C++ is not his favorite programming

Nicolai Josuttis: You know, I didn’t follow the standardization process of C++11. At the end of 2008 I looked first into the new standard by comparing the C++98/03 versions of classes, such as pair and vector, with their new versions. I was shocked. I had trouble understanding what I found: “What the hell does && mean in declarations?” So if you ask me about the difference, my first answer is: Everything is different! The way you write simple programs and the way you define complicated classes have changed dramatically. C++11's pair<>, for instance, doubled the number of lines.
Nevertheless, the changes go in the right direction. C++11 consequently focuses on the power of C++ -- performance. However, it still has the drawback of making it even harder for programmers to design good classes. Well, it might not be harder, if you know all you have to know; but it’s harder to know all you have to know, now. To some extent, C++11 is a new language, and my new edition simply reflects this change, covering both the new C++ programming style and new classes.
