Neale's prediction is the one stated.

Los Angeles Population (Blake)
|
||||
------------------------------
|
||||
==============================
|
||||
|
||||
On Feb 24, 2029, the metropolitan area commonly known as "Los Angeles"
|
||||
will have, at most recent measure, double-digit population decrease.
|
||||
|
||||
|
||||
Neale's Rationale
|
||||
-----------------
|
||||
|
||||
LA uses a ton of fresh water, brought in from all over the place.
|
||||
As droughts worsen, there will be increasingly large fights over water.
|
||||
Regardless of the political outcome,
|
||||
places closer to fresh water will tend to keep that water.
|
||||
LA is not close to fresh water.
|
||||
Las Vegas is going to have the same problem,
|
||||
but predicting the collapse of Las Vegas didn't seem as challenging.

This Page (Nemo Thorx)
|
||||
======================
|
||||
|
||||
|
||||
By 7 December, 2028, Neale will have updated this web page
|
||||
within the last 12 months.
|
||||
|
||||
|
||||
Neale's Rationale
|
||||
-----------------
|
||||
|
||||
I actually think Nemo's right,
|
||||
but this was such an amusing bet,
|
||||
I couldn't turn it down.

|
||||
|
||||
DC Power (Nobody yet!)
|
||||
======================
|
||||
|
||||
By 2030, over ⅓ of US residences currently being built will be wired with a DC power bus.
|
||||
|
||||
|
||||
Neale's Rationale
|
||||
-----------------
|
||||
|
||||
When I counted in 2014, we had only 5 electrical devices
|
||||
that used Alternating Current.
|
||||
Everything else ran off a "wall wart":
|
||||
an AC to DC transformer.
|
||||
|
||||
In addition to DC being tremendously safer
|
||||
(it won't stop Junior's heart when he sticks a fork in a USB port),
|
||||
it's also potentially more efficient to have a single transformer for the entire house.
|
||||
As more houses move to solar power with battery storage,
|
||||
the conversion from DC batteries to AC wall power,
|
||||
just to be converted again to DC,
|
||||
will be a tantalizing inefficiency to conquer.
|
||||
And with the introduction in 2015 of USB delivering up to 100W,
|
||||
there will even be a standard to use.

I recently switched to Xubuntu from Arch Linux.
|
||||
I'm not sure I'll stay here, but I got tired of maintaining my one-off
|
||||
/sbin/init that uses runit.
|
||||
Linux distributions are all heading toward systemd,
|
||||
which I strongly dislike. But I figure it's time to catch up
|
||||
and abandon understanding how the computer boots.
|
||||
I run Arch Linux, with a shell script PID 1 that I maintain because I enjoy tinkering with early userspace.
|
||||
It uses runit from busybox to manage starting and stopping daemons.
|
||||
Runit is a lot like systemd or upstart at core: daemons don't do the double-fork trick, and log to stdout.
|
||||
|
||||
On the desktop, I run Google Chrome, xterm, and acme from plan9port.
|
||||
My window manager varies a lot.
|
||||
Most times it's Openbox plus tint2, but sometimes I go back to 9wm (which I maintain).
|
||||
I'm starting to make overtures at Wayland.
|
||||
|
||||
Occasionally I kick up inkscape or gimp, and mixxx for my DJ work.
|
||||
Most of my non-work computer use is through Chrome, which ties me strongly
|
||||
to Linux, for better or worse.

What would be your dream setup?

A Chromebook that had Acme and my development tools.
|

I really like how my wife's Chromebook updates itself,
|

and how it doesn't need dozens of mystifying apps in the default menu.
|
||||
I'm actually not too far away right now.
|

I like working in the cloud, and for my development stuff,
|
||||
acme is pretty great.
|
||||
|
||||
Some day I may figure out how to get Chrome to expose its window manager,
|
||||
and then I'll probably abandon all of XFCE4,
|
||||
since I don't really use it for anything other than kicking up Chrome
|
||||
and acme.
|
||||
I spend a lot of time fretting about window managers.
|
||||
Hopefully I can move to Wayland soon, and port 9wm to it.
|
||||
Or maybe I can get Chrome to expose its window manager.
|
||||
|
||||
I kind of wish I didn't need a gazillion packages in order to run my 3 main programs
|
||||
(chrome, acme, and xterm).
|
||||
But I don't know how I can fix that, and I'm not sure I really even want to.
|

I would also like to do away with the FitPC print server.

I'd love to be able to buy a little box that will hop on our wireless network
