Believe this is one of the few vendors left making and distributing Linux magazines still(?). Would be interesting to hear what peoples feedback on these are, whether its this one or another. Seems like a fun monthly delivery to get!

I used to read them, they often had good in depth tutorials. The Format branding has been going for a long time, I can remember reading Amiga Format.
There were a few other Linux magazines as well, Linux User, Linux Magazine, Linux Voice. I think there’s still a Raspberry Pi magazine as well which covers a lot of Linux stuff.
