By happenstance, the [cool] dude also came on radar where I, too, noticed his Merit count, hence asking him privately if he's gmaxwell. He timely replied in kind and ask me if I would [kindly] ask the question in this thread. I told him to go kindly fuck himself. 
This is not the first time Ive had such a query; and last time was from someone with a five-digit uid. Thus I wished the opportunity to address the matter clearly in public, without coming off as if I were the one suggesting the connection.
Im not gmaxwell. Though in terms of technical virtù and Bitcoin prowess, being asked if I am is some of the highest praise Ive received here. Indeed, it is a bit overwhelming; for due to my background, Ive had to admit to him my inadequacy in maths and comp.sci:
Sipa also has AVX2 8-way sha2 and ripemd160 that he might post somewhere if you asked. An 8-way bech32 checksum generator should be really easy to do,
Will ask. Actually, I think I may have this mentioned somewhere in GH discussions; I didnt pay attention, because I dont yet own any machines with AVX2. Not quite as rich as people think I am.
Also, for the record: nullius is a nym I picked quite some years ago, and became far too attached to. I had the nym reserved for some special future project long before I heard of /u/nullcso yes, some years ago.
PS: Don't click on any links he provides, for they're ALL diatribe traps. 
Thanks.
Ive been preparing a special diatribe for this thread. You didnt think Id not reply here, did you? But those take some time to write. Ill be back.
