Gnu Hurd on Guix

It is a simple process to build a Hurd vm from Guix:


christopher@nightshade ~/Scratch$ guix build -S guix
/gnu/store/f8qhkr6lzzmw7a5v44nqvbi1gg8cyh85-guix-1.1.0-4.bdc801e-checkout
christopher@nightshade ~/Scratch$ guix build -f /gnu/store/f8qhkr6lzzmw7a5v44nqvbi1gg8cyh85-guix-1.1.0-4.bdc801e-checkout/gnu/system/hurd.scm
/gnu/store/4l65yggpi0v6y9pi8q7aij17zx28wyzp-qemu-image
christopher@nightshade ~/Scratch$ cp /gnu/store/4l65yggpi0v6y9pi8q7aij17zx28wyzp-qemu-image ~/Scratch/
christopher@nightshade ~/Scratch$ sudo qemu-system-i386 -enable-kvm -m 512 -snapshot -hda 4l65yggpi0v6y9pi8q7aij17zx28wyzp-qemu-image

The VM from this config does not have guix (package manager) installed, so it is somewhat limited what you could do with it. (I think there is a fancier version in a Guix development branch somewhere.) But guile scheme is installed already!

From what I understand, before Guix, Debian was the only distro that had made a Gnu Hurd system practical. But Guix is making rapid progress. I believe the benefits of Guix development investment in Hurd will be more enduring also, due to the functional nature of the Guix package management system.

Not claiming there is any real mathematical genius behind this idea, but it seemed interesting enough to share. I was wondering what would happen if you build your next Z by plugging the magnitude of Z in as your real coordinate, and the angle of Z as your imaginary coordinate. I.e., abs(Z)+i*angle(Z), or in xaos abs(Z)+{0;1}*asin(im(Z)/re(Z)). This is it:

I found that the image is more visual stimulating if you dampen the real component by a factor of 0.5:

Amateur Log KL1TL 20200506

Stationed my GMC at Hagelbarger Lookout, Fairbanks, at about 7:45pm AKDT, tuned to 3920 kHz, with the multiband antenna. Received local communications from WL7CW, KL4QZ, and KL4VN, who indicated good copy. Then was able to listen in to the Alaska Bushnet. It sounded like, as near as I could tell from all the rapid communication and people communicating over each, that I was hearing pretty nearly everybody who was checking in, at various levels of volume and signal clarity. I’m not sure of the furthest locations I was hearing, because it was hard to keep track of who was naming their location and who was naming a relayed location. But I got a strong signal from someone in Talkeetna, and somebody in Clam Gulch, which is on the Kenai Peninsula. And I could hear the net controller (WL7CXJ?) though his station sounded weak.

It seemed that the net controller could not hear me, but somebody relayed me in.
