Seriously, don't worry.  I love visiting Berkeley, which has all sorts
of good memories and special places for me, and for reasons I discussed
with you on the telephone a short while ago, I was really delighted to
have a nice Sunday road trip to there and back.

Affirmative.  Much fun can be had:
https://www.linux.com/tutorials/intel-edison-linux-maker-machine-matchbox/
It's kind of impressive to get a dual-core Atom CPU, 1GB RAM, 4GB of
flash storage, _and_ Arduino compatibility on something the size of an
SD card (1/6 the size of a RPi).  Especially given out for free:  Intel
had spec'd this for a $50 price point, about.

As the (above-cited) article points out, the GPIO pins running at a
(low) 1.8 volts is an obstacle to doing much analogue-ey stuff until you
do voltage shifting with ancillary hardware.

It'll run some major distros, or at least walk them briskly.  (Comes
preloaded with Yocto Linux image for Edison.)

The MySQL command-line interface is a pain in the tochis.  On any system
where you have PHP going, you can help yourself a great deal by using
the Adminer tool, a single-piece PHP front-end to MySQL (and thus to
MariaDB):

https://www.adminer.org/
(As the Web page suggests, the author was inspired to write it by just
how ghastly a piece bloatware spaghetti code the _other_ thing usually
suggested, phpMyAdmin, is.  He succeeded in vastly surpassing the
competition, by making something that's equally functional, but tiny and
fast.)

Once you've gotten used to that, having to deal with /usr/bin/mysql will
seem like wearing the hair shirt, trust me.

Respects for that.  Next time I attend, I can use the occasion to
motivate me to do something with my spare WRT54G.
