Lot of admiration for no starch - your books are great !

I wish I had more of them. I maintain a modest library made out of real paper and I'm so glad No Starch still has good quality paper and excellent binding. I have a few of the more recent print on demand O'Reilly books but they feel more like cheap print outs I could have done myself. Unfortunately they are just so expensive so I do have to be very selective.

Yeah. My favorite are books that guide you through implementing complex systems projects from scratch, like Nora Sandler's "Writing a C compiler", or Sy Brand's "Building a Debugger". I wish they produced A LOT more of them.

Those are some new and very very shallow books. There better one's from 90" and 80".

Per Dr. Marshall Kirk McKusick (as announced in one of the recent BSD conferences), No Starch Press will be publishing the third edition of the Design and Implementation of the FreeBSD Operating System book sometime later this year.

I'd love something similarly scoped centered around nftables. Does anyone have a suggestion? I see No Starch has a Linux Firewall book, but it's from 2008 and is thus iptables-based.

Was thinking I had missed an entire edition of Pathfinder for a moment upon reading the title

It's a great book, I used to have some edition of it and it helped me a lot professionally with setting up firewalls, load balancing, traffic shaping and more.

I also had a book on Designing FreeBSD rootkits that was very educational.

Unfortunately I've given away all my books for more minimalistic living where I am instead dependent on digital information. Not sure how to feel about it.
