There seems also to be a conveniently available 1998 version[1] which, unlike the version linked in the OP, contains still-working links to several additional chapters.[2-6]

I don't know how the content compares to Chaitin's books, including The Unknowable (1999).[7]

Yep! Thanks for the suggestion! Apparently -1 is the same as --fast. See comment below by geocrasher: "gzip --fast. Only 23% slower in speed, but 73% reduction"

Darkstar is a traditional name for computers running Slackware.

Shameless plug: My gorgeous Darkstar is an antique server on which I sell traditional shell accounts from which one can make "metal" VPSes from the command line. Occasionally somebody who knows 10X or 100X or 1,000X more than I do comes along and becomes a customer. If you are interested, please check metalvps.com. Also, if you like Xv6, please check metalvps.com/Xv6.

It's been a few days, but I still had the original files in their original locations. So:

  root@darkstar:/usr# date -u; time gzip < local-revert.tar > local-revert.tar.gz
  Tue Oct 11 02:49:32 UTC 2022

  real    24m35.214s
  user    23m57.449s
  sys     0m27.327s
  root@darkstar:/usr#

From the linked article, for convenient reference, making the .tgz file with tar cvzf took about 28.2 minutes. Making an uncompressed .tar file took about 1.2 minutes. Just now, compressing with gzip took 24.6 minutes. It seems, in this situation, about 2.4 minutes might be saved by creating the tar file first and then compressing separately.

Earlier today I sent our first Xv6 Study Group email blast to the 15 people who have signed up. Also, I started a simple website for the group:

https://metalvps.com/Xv6/

I wasn't expecting such a big response! Thank you to all the guys who joined! Thank you HN!

So far, ten people have emailed expressing interest in joining our Xv6 study group. Plus three more said hello.

My idea is to start on the course itself tomorrow or the next day. I expect to invest at least an hour a day in the course itself. I also expect to post my notes and progress somewhere.

We can fill in the group structure as we go along. Maybe we all can keep in touch via email, irc, Jitsi, an HN thread, or set up our own Xv6 study group forum?

I am delighted to be in contact with so many other students! We have room for a few more if anyone else wants to join. Thank you all so much!

Oops! I just checked my email! There seem to be several more responses. I will get back to everyone ASAP.

We might even have room for even a few more!

Thanks guys! Thank you HN <3

Hi Markus!

Thanks for your kind words.

I read your comment[1] which explains what you are doing and suggests by implication why you might think you are insufficiently prepared.

However, no law requires perfect preparedness. Why not take a few small bites of delicious dessert and see how they taste?

Best wishes and kindest regards,

Tom

Hello again!

Already have one person for our Xv6 study circle! Thank you HN! Anybody else?

I'm going to sleep now, but if anybody emails me, I will for sure reply in the morning.

Best!

Hello!

I have an antique server with qemu set up to run Xv6.[1] I wanted somebody to go through the course with me.[2] So far nobody has come aboard, and I haven't really started. If anyone here might be interested, please feel free to get in touch: [email protected]. It would be super great to have a few friends along! Thank you!

Best wishes and kindest regards,

Tom
