XOR A absolutely works on Z80 and it's of course faster and shorter than loading a zero value with LD A,0. LD A,0 is encoded to 2 bytes while XOR A is encoded as a single opcode. XOR A has the additional benefit to also clear all the flags to 0. Sub A will clear the accumulator, but it will always set the N flag on Z80.

I think the answer is in the article text "all meticulously sectioned by publisher". Book sizes differ somewhat between publishers, but each publisher tends to only print books in a few standard sizes. For the paperback editions this is even more reduced, it usually looks to me like all paperbacks from one publisher are the same size.

I always thought it to be the other way around. If you assume that we are living in a simulation, then gravity might well be an artifact of a simulation that runs on localized, loosely coupled nodes. Because when you have mostly empty space, with low interaction, then the simulation is able to run at full speed, but the more particles you have interacting at close range, the slower the simulation gets as the local workload increases. In this model the force called gravity would not be the source, and time dilation one of it's effects, but instead time dilation caused by interactions is the cause and the gravitational force is what we experience as the result.

I just ran into the same issue yesterday when I was updating one of my machines. Furtunately I caught the DKMS error when mkinitcpio ran after the upgrade:

  ==> dkms install --no-depmod zfs/2.1.9 -k 6.2.8-arch1-1
  Error! Bad return status for module build on kernel: 6.2.8-arch1-1 (x86_64)
  Consult /var/lib/dkms/zfs/2.1.9/build/make.log for more information.
  ==> WARNING: `dkms install --no-depmod zfs/2.1.9 -k 6.2.8-arch1-1' exited 10
Issues like these are when being on a rolling-release distro might bite you.

To mitigate the risk a bit, I always have the linux-lts kernel package installed on all of my Arch Linux machines, which provides a fallback option when the mainline kernel fails, or some major kernel issue surfaces. In my case with the LTS kernel at 6.1.21-1-lts, DKMS build of ZFS on LTS succeeded, so it would have been a fallback option to boot even if I would have missed the error for the mainline kernel DKMS.

  ==> dkms install --no-depmod zfs/2.1.9 -k 6.1.21-1-lts
  ==> depmod 6.1.21-1-lts
I don't have my root on ZFS, I only use it for data storage, but if I ever did,I would make damn sure to build myself a live ISO with ZFS support and all drivers necessary for network access, ahead of time, in case I need to do an emergency repair. It doesn't need to always be on the latest kernel, just recent enough that you are able to mount all partitions and to chroot into the system.

For this issue a workaround with Kernel 6.2.8 is discussed in the AUR comments for zfs-dkms: https://aur.archlinux.org/packages/zfs-dkms This would involve editing the PKGBUILD for ZFS to patch the license for the symbols to GPL, though I'm not sure about the legality of this approach.

There's more to the story than that.

The last German government before Merkel came to power, was a coalition between the Green party and the Social-Democrats (SPD), this government decided to phase-out nuclear power in Germany in favor of renewable energy by limiting the running time of existing nuclear power plants.

The next German government was a coalition between conservative CDU under Merkel and SPD, and the nuclear phase-out remained untouched.

But when Merkel won the federal elections a second time and was able to form a coalition with the Liberal-Democrats (FDP) replacing of the SPD as a coalition partner, who had voted in favor of the nuclear phase-out, they decided to cancel the nuclear phase-out.

This happened in the autumn of 2010 and was a controversial decision for the public opinion. When Fukushima happened half year later it was widely seen as a confirmation of the inherent risks of nuclear energy and thus the Green party’s energy politics, not because Germany is especially prone to Tsunamis, but because it showed that it's impossible to rule out and plan for every possible dangerous situation in advance, and that even a high-tech country like Japan, on a comparable technical level to Germany, was not able to stop the meltdowns.

Elections in federal states shortly after Fukushima resulted in a landslide loss for Merkel's CDU and big wins for the Green party, the CDU losing one of its stronghold states [1] it had before held constantly for 58 years.

As far as I remember Merkel foresaw the public reaction and almost immediately after Fukushima voiced out in favor of reversing the cancelation of the nuclear phase-out, but could only get a solid backing in her party, after the losses in the federal state elections.

Some other webcomics I remember from that time:

- CFRH or College Roomies from Hell, still ongoing although at a much slower pace: http://www.crfh.net/

- Sabrina Online, started 1996 by Eric W. Schwartz of Amiga fame: https://www.sabrina-online.com/

- General Protection Fault, like the name suggest, this one also has an IT setting: https://www.gpf-comics.com/

- Roomies! and It's Walky! - A teen romantic comedy: http://www.itswalky.com/

- Argon Zark, this was the first web comic I discovered, seems to be going back to 1995: https://www.zark.com/

If you would like to have more background information, here is a great thread about Chechen history and Kadirovs rise to power in view of this conflict. https://threadreaderapp.com/thread/1497612331953577991.html

I would recommend Kamil Galeev threads to anyone interested in the history of Russia and Ukraine, he has written a ton of threads about a lot of different aspects to the Russian/Ukrainian conflict, which all look very well researched to me. I'm not sure I agree with all of his conclusions though.
