The HTTP response code for fresh.flatassembler.net assets is "200 She'll be apples", I didn't know 200s could be customised like that :)
Hahah, proper Aussie mate! (there's a compile-time flag to make them all boring instead of our homage to Aussie slang haha, cheers and glad you like it)
Question. I've just started to become interested in learning/messing around with assembly language under Linux, and fasm seems like a really attractive option - as and nasm are both tied to gcc (nasm indirectly), and fasm skips all that (and produces slightly smaller binaries too!). fasm also seems compiles itself in less than a second on my really old machine as well, and fast iteration time is one of my favorite features.
Linux-specific assembly-language documentation is kind of rare on the ground though; for fasm in particular, there's literally hens' teeth and dust bunnies. It's very possible to piece things together, but if you have absolutely no idea what you're doing it's a bit intimidating.
HeavyThing is practically a tutorial in and of itself, but I must admit my hesitancy to lean too heavily on it due to its use of GPLv3. I certainly respect the use of that license (and understand the many reasons it might be used for such a unique project), but I'm only tinkering around myself at this point so would likely want to use MIT, CC0 or similar, and would feel a bit conflicted about the predominant thing I learned from being from GPLv3.
HT is on the list for sure, but I wanted to combine it with other sources of info. You seem to be one of the few people out there actively using fasm for Linux development, so I figured it couldn't hurt to ask if you had any other high-level suggestions.
