Update: I have found a much easier way, using QEMU's built-in
Samba. See QEMU Windows Guest: Sharing Files with the Host.
Unexpectedly, one of the hardest parts of
Migrating
a VirtualBox Windows Virtual Machine to qemu/kvm/virt-manager
was finding a way to exchange files between Linux and Windows.
In virtualbox, setting up a shared folder is trivial.
In QEMU, not so much.

This is the first of two baby fence lizards that got into the house in
the last few weeks. I guess I can't really blame them: it's getting
cold outside, even for an endotherm.
It's funny how we always start seeing lots of baby lizards when the weather
seems like it's getting too cold for reptiles to be out and about.
Maybe the little ones just haven't learned yet that they should find a nice
burrow to wait out the winter.
We usually capture spiders and crickets in the house with a cup and
card, and escort them outside.
But lizards are a lot harder to capture than spiders.
Even with cooperative hunting — Dave holds the cup and sneaks up
on the lizard while I try to herd the lizard toward him —
lizards are fast, and there are so many possible hiding places.
This lizard didn't duck under the cabinets, the hole you can see in
the photo. Instead it went the other direction and dove into the
heater vent. We pulled the vent cover and left a little ramp so the
lizard could get back up easily; later in the day, we found it, caught
it and escorted it outside. As we did the second lizard (assuming it
was a different one), a few days later.
I hope they've found a nice place to hibernate.

I've long been wanting an "action camera" to shoot mountain biking, and
maybe R/C plane, videos.
Last week I ordered an Akaso V50x.
Everybody seems to agree that Akaso offers the best bang-for-the-buck, but
choosing among Akaso's large and varied collection of models isn't easy,
especially since there aren't many comparisons between the V50 line
and the Brave line. The V50x was well-liked by most reviewers,
and gets high praise for its digital stabilization ("6-axis", which
apparently means three axes of translation plus three gyro-driven
rotation axes).
I worried, though, that all the sample V50X videos I found on YouTube
were severely underexposed, and I had written it off my list until I
stumbled upon a review that listed all the V50x Settings options and I
learned it offers exposure compensation (which it calls "Exposure
value").
In the few days I've had the Akaso I've been fairly impressed.
The stabilization is indeed very good — if anything, it's
almost too good,

Ever since I got my Lenovo Carbon X1, I've wished there was some way
to limit the battery charge. I keep it plugged in to a USB hub and external
monitor most of the time, which means that the battery is at 100% for
weeks on end. That isn't particularly good for lithium ion batteries:
it's better for battery life to stop charging at around 80%.
Lots of laptops, including Dells and Apples, have a charge limit feature in
their BIOS, but I searched through the CX1's BIOS several times and
never found anything, so I'd resigned myself..
But just this week I accidentally stumbled on a way to set this at runtime!

I wrote in midsummer about the fun Dave and I were having on our
Lectric ebikes.
We've been riding the Lectrics most days for errand running and jaunts
across town,
and it's gotten us back into pedalling our regular mountain bikes again, too.
But then one day a big box showed up on the doorstep. Dave had been
lusting after a different sort of ebike: a Jackrabbit.
