[ale] Yea!! Android emulator working after 1/2 hr hair pulling

[Michael Trausch]

I will try to remember to reply in full later. 

That said, it isn't a step backwards at all. It is more efficient for most applications, because they do not need the larger registers or the full memory space above 4GB.

The x32 ABI allows most apps to be 32 bit, while using 64 bit apps for things that need the extra oomph. That means more pointers for in the CPU cache and that means a performance increase for apps that do not require longer pointers or larger memory space. For example, there is no reason that Pidgin requires > 3 GiB of user memory, so it should be a 32 bit application.

Nobody is paying me to learn linux, manage it, or solve problems.  I have to do all this on my own, with a minimal budget, to solve specific problems I'm interested in or learn things.  I, fundamentally do enjoy learning new things.  However, using the android emulator experience as an example, it has been tedious, time consuming, and frustrating.  Hopefully, there will be rewards down the road.  So, even if I were willing to spend weeks, for example, learning about some of the more esoteric topics involving linux, those are also weeks I would not be spending writing or learning blender, for example.  It's always a trade off to consider how much time to spend on one thing, versus another.  See my reply to Phil for additional perspective.
