If you're looking for recommendations for other zines, here are two (though both TXT format):
- https://phrack.org/ - well, this one you probably have heard about ;) (it has a printed form as well, but I think you have to actually find it on an event)
- https://tmpout.sh/ - this one focuses on Linux executables
But if you don't mind older content in amazing artistic forms, do check out old demoscene zines like Hugi: https://www.hugi.scene.org/ (note: these are in form of EXE files - that was pretty typical for scene zines)

I don't know if there's a good way to search for them. Most of the Lovebyte entries can be found on pouet or demozoo.org but I don't know if there's an easy way to filter out only Linux entries.
I've written a few sizecoded raspberry pi entries, there's even a writeup of one of them in tmp.out where I loaded some code into the ELF headers https://tmpout.sh/3/08.html

If anyone's interested, last year I replicated this exercise for an x86-64 Linux executable [0], and also golfed a Hello World as small as I could. I ended up using a little-known pattern (an ET_DYN executable with no interpreter, normally only used for the ld.so binary) to shave off more bytes than anyone else who had tried it, to the best of my knowledge.

By the way, this article is published as part of the tmp.0ut zine, and the CFP for the next issue is currently open: https://tmpout.sh/blog/vol4-cfp.html
