Wow cool! Great stuff! I guess I really like the old days of computing where efficiency and every Hz mattered, I frankly don’t understand why the 2.66 GHz Core 2 Duo with 2 gigs of RAM in my iMac is sooooo slow sometimes on a modern OS when as I recall on my BLAZING 50 MHz Amiga I had NO such slowdowns.
I know, I know, applications like modern internet browsers require massive processing power to play the multi-media content we so enjoy and all this power is relatively cheap, but can’t we just scale it back 'a little’ to make it work well on an eight year old machine like mine? I know it IS possible with SLIGHTLY different priorities as to where this power is used in an operating system to make things work better but that doesn’t encourage the purchase of new systems which makes world economies work! The open Unix OS variants are, I suppose, the best example of this, but I REALLY like the Mac OS environment and hardware, it seems to be the modern vision of what Amiga would be. I will cut this off in a minute before it turns into a multi-page rant about system design and needs but I will say it seems we are truly living in a ‘post PC’ world: Most people don’t really NEED a computer for the daily activities of life, our iPads and iPhones do what we need (they now have ALMOST as much processing power as this old iMac!) It seems when they hit ‘the GHz ceiling' of about 4 GHz eight years or so years ago, they couldn’t go much faster so now just ‘add cores’ and increase efficiency, they are now up to 1000 cores that runs off of a AA battery! Max 1.78 trillion operations per second!!! But people in general DO NOT NEED such speed when a five year old, quad core, sub 4.0 GHz computer does everything we need at reasonable speed, why upgrade?!? Of course, I WANT a 1000 core computer, if just to see what I could come up with to use all that power for! http://www.digitaltrends.com/computing/1000-core-laptop-aa-battery-energy-efficient-uc-davis/ Anyway, thanks for the links, lots to ponder there...
