Fun fact: Processors I've either read or hand-crafted assembly language for include (but isn't limited to) the following:

R/W:

- Z80A
- 6510 / 8502
- 68000
- 80x86 16-bit
- 80x86 32-bit
- PowerPC
- MIPS R3000
- RISC-V (obviously)
- S16X4 (my own CPU design)
- SEAforth 24
- GreenArrays GA144
- Offete, Inc's P32

R/O:

(All of the above plus...)

- RCA 1802
- TMS9900
- DEC VAX
- PDP-11
- MuP21
- Novix RC4000
- Harris RTX2000

Yeah, I think I know a thing or two about assembly language. ;)

If you're the type of person who posts memes or wishes of ill-intent upon people's homes and livelihoods, just block me now; for, if I find out you post that kind of shit, I will without warning or concern block you immediately upon seeing it. If I deem it severe enough, I'll also report you for hate speech.

"If you are not a ________, fuck off." (Insert your favorite adjective in the blank provided.)

When I read this, especially on the Fediverse, I get pissed. What did I do to warrant fucking off for, when I never met or interacted with you in the first place?

Shit like this results in an instantaneous block from me. I don't need supremacism, however unintentional or jocular, in my life.

"It's just a joke!" Yeah, that's what the nazis said too, remember? Go pound sand!

Since this was such a huge problem on Twitter recently, I thought I'd make a similar announcement here on the Fediverse.

I'm just going to put this out there loud and clear right now.

If you are the kind of person who thinks that Dennis Ritchie is a somehow GOD, who can do no wrong, who has made no mistakes ever, including wrt your beloved C programming language, BLOCK ME NOW.

Hey fediverse bot authors, this is for you.

Instead of having a bot that blindly follows someone, then having a pinned toot or description that reads, "DM me "unfollow" if you don't want me to follow you any more", how about you do something sensible like looking at a user's profile and discovering whether or not they have #nobot in it first?

Because if you write bots that don't respect #nobot, you're no better than a spammer.

Don't @-me.

The finished result:

Unfortunately, I didn't think to check in the original code for comparison.

So, today, I took a chunk of Z80 code that I'd written to satisfy a unit test and rewrote it to a more optimized form (read: hits memory less often, making better use of registers).

I did this by hand-decompiling the code into a pseudo-functional program, then hand-re-compiled it into SSA form. I did liveness analysis and whole-procedure register allocation.

I'm damn proud of what I came up with.

Hooray for blind spot in my left eye, with all manner of geometrical and crystalline shapes and colors.
