80% of Mac OS X was rewritten to Snow Leopard
He spent a week now since Mac OS X Snow Leopard went on sale for all mortals. He talked about many things, I deeply analyzed and highlighted all its aspects. But one aspect of which little or nothing was said about the source code was the same. Rodrigo Gomez, manager of new business for Apple Latin America said about it:
It is one of the most important updates to the operating system has had to date, with a rewrite of nearly 80 per cent
That is, practically rewrote the entire Operating System. A remarkable achievement which few would be enthusiastic to do. For example, even though Microsoft is aesthetically changed much, its source code has no major modifications.
And speaking of aesthetics, Rodrigo said:
While the interface is different, a little smarter, its use is more or less the same. Thanks to increased performance provided by the Mac OS X v10.6 users will not see differences … but it will feel.
While not using Mac OS X, I think there’s the essence of his philosophy. You do not necessarily have to notice all the changes that are made with just enough to feel the change. Maybe that’s why Windows 7 is so praised, so changes are not noticeable, but if performance.
On the changes of Snow Leopard, Gomez stressed that applications are written once but the system compiles for 32 and 64 bits. Also do not forget OpenCL technology, which leverages the processing of the graphics card when not in use.
As expected, Apple is doing things right, let’s talk about quality and usability of the software.
