In this article
I talked about a mission to phobos instead of mars. But that has the ultimate
drawback of too little gravity. Astronauts doing the trip will need to work
out and replenish their bone marrow and muscles. So landing on Phobos is not
a good idea, we need Mars' gravity.
However, I'm more a proponent of having humans land in a polar region of Mars
the first time AND use the concept of Avatars being stationed around the
equatorial region. This means command and control is in the "white" region and
robots running around near the equator. But why? Because the cold may kill
any bacterial life that we don't want returning to Earth. But it would also
be damn cold for humans so we'd need nuclear generators most likely. I
imagine the first human marstronauts will be inside their habitat controlling
the robots 2000+ kilometers away, and then working on their own health with
gym equipment. A trip out of these modules would be infrequent.
You'll thank me for this brainstorm when no martian virii make it to earth
after the voyage home.

Happy New Year 2021
January 1st, 2021
I think it's gonna be a good year. New years propositions are that I want to
get a job. I also have started 3 projects already last year. I'm giving
freifunk a shot again. I hope it won't rob too much of my time. Also I have
committed time to attempting to make my G5 run OpenBSD 64-bit. I committed
12 months for that so we'll see. And then there is my DNS server which may
take a backseat to the other projects, meaning, that it may not be done
everything by years end, but most likely next year some time. We'll see how
it all unfolds. So 2021 is like the other years with recycled content. Old
to the new :-).

Raspberry Pi 4B and Network Map
December 29th, 2020
I got a Raspberry Pi 4B for Christmas from my parents. I'm writing this
blog post on it. Everything works except sound basically.
Here is my updated Network Map:

Solstice is tomorrow. Will we also see the "great/grand conjunction"? Looking
out today I have my hopes down for Franconia region of Germany, everything is
overcast.

Things OpenBSD...
December 14th, 2020
I have two great news:
- OpenBSD foundation is $4,000 CAD away from reaching their fundraising goal.
They'll likely make it with two odd weeks left in the year. Congratulations
to OpenBSD! And a big thanks for everyone who donated.
- I have committed time from late January to December 2021 to (as a hobby)
attempt a backport from the OpenBSD/powerpc64 architecture to the Apple G5
machine (I'll call it OpenBSD/macppc64 from now on). As I have about a year,
I'll try to make it work. I did have involvement in the RISCV64 group but I
really want to make my G5 work with 4/8 GB of RAM.
I did attempt a G5 port before, in 2018, but failed. Chance has it that I can
reuse some of the files I modified back then in this effort so it wasn't all
wasted time back then. I'll be focusing on the ofwboot bootloader to compile
a FDT binary blob tree on the fly translated from openfirmware. Since both of
these are in compatible trees (I think) this should be straight forward work.
Once I can boot with a FDT blob in memory we don't have to use openfirmware
anymore and can go ahead with simplebus framework that has a lot of support.
It will be enough to at least make the kernel print pretty stuff (like config
dmesg output). Then comes a hard part, the userland. By then OpenBSD will
likely change powerpc64 port to little endian and macppc64 will likely stand
on its own in big endian.
If you have an Apple G5, and know how to program C and asm, I invite you to
work with me. End of January I'm going to put it all available on github.

Today is International day of Human Rights
December 10th, 2020
On chat I was joking around about aliens on earth this morning. Yet there is
something much more important. Human rights day (UN.org) is today, and is associated with
the universal declaration of human rights (of planet earth), this isn't a joke these rights are universal, if you don't know, now you know. Everyone has
a right to know them, violations go against humanity universal laws.
Still if you're an alien on planet earth you should also have rights. Even if
you are a human that time travels you should be protected by these rights. In
my view if you are a time traveller you need to be put into a new clause. In
1948 people did not fathom the Internet or even AI. All AI must adhere to
these rights when dealing with humans, this is very important. It's incredible
that just recently there was a spat with an engineer of google who was "sacked"
regarding some email that mentioned marginalized people. Google should really
get an ethics (if that's a word) committee that adheres to human rights.
