Re: [ydl-gen] Linux yellow dog manual for dummies

Thanks, Derick.

Although this is a YDL forum, I am afraid to say that there is no  
comparison between any linux on PPC and OS X. The former simply  
doesn't have the software base that I need. I used to think that it  
would be faster than OS X, but after a few installations of linux on  
Apple computers, I discovered that OS X wins hands down in the speed  
area as well. I think that linux is optimized for x86 and of course  
things like flash are only available on x86 linux (I hate flash, but  
it unfortunately has become a standard for internet video). There are  
still some PPC optimizations in OS X apps and maybe even some Altivec  
usage (which allows Quicktime to smoothly run at 1080p on my PPC  
machines). The tasks involved in writing my book would have been  
enormously greater if I had used linux instead of OS X.

I notice an increasing dominance of ARM in low power portable devices.  
This is unfortunate, since ARM simply doesn't have the computational  
power that PPC has - I am not sure it even has a floating point data  
type. It is too bad that IBM did such a poor job of promoting PPC; we  
will need to reinvent the wheel with ARM when we could have had  
advanced multi-purpose chips with low power consumption from the PPC  
manufacturers (such as PA semi, which Apple bought and converted to  
ARM).

Anyway, the improvement in the performance of Apple products since the  
switch has been less than stellar, much less than expected from  
Moore's law. My 4 year old G5 has a 1.15 GHz memory bus and an 16x  
dual layer superdrive, which is very competitive with the best that  
Apple can come up with now (for reasonable prices). It cost much less  
than a current machine and doesn't require a several thousand dollar  
investment in software, which I would need to make if I use one of  
Apple's intel superboxes.

Cheers,
