I don't really spend much time on YouTube anymore. Probably for the better :)

OK -- I finished a prototype for my custom mono-field floating-point format, in Golang. I haven't done extensive testing, but it works fine so far -- addition, subtraction, multiplication, and division.

One of the distinguishing characteristics of it is that the amount of bits *available* for the significand varies based on the exponent. You get between 0 (yes) and 32 (yes) bits for the significand.

I think I'll put this up on #GitLab at some point.

Random #computerScience observation that is quite useful sometimes: X - Y < 0 is the same as X < Y.
Not sure if something wonky could happen with overflow to prevent that from being true, though

Ah OK, from `go doc -all math`:
MinInt32 = -1 << 31 // -2147483648
OK. Annoying that I can't just enter what I want, but oh well.
(I still love this programming language :) )

: go run monofieldfloat.go
# command-line-arguments
./monofieldfloat.go:92:17: 0x8000000F (untyped int constant 2147483663) overflows int32

#Golang isn't letting me type in constants that are supposed to be "negative", and it's getting really annoying. I'll type in 0x8000000F (in this case) for an int32, and it is like MaN tHis is JUst tOo LarGe and I'm like :|
#programming

It is written in a programming language I made, called Slang. I had to write the compiler for it, and I have my own stdlib and emulator to run the compiled code.
I am quite happy so far; it's a bit of a dream.

#SubSky #CPU #ISA

Working on a novel (hopefully!) floating-point format for my custom CPU #ISA . It doesn't have any floating point operations -- as a matter of fact, it only has 16 operations ("instructions") -- but I'm working on a floating-point format optimized for software emulation on it.
That said, I already have in my stdlib macros for fixed-point #math (Q16.8 format), as well as a sine function and sqrt function.

Lemmy: a missed opportunity to call a Fedi reddit Feddit.
#Reddit

That said, I'm finally gonna be more active on Fedi. Being able to stream out into the Internet like this is going to really enable me. #Fediverse #musings

Being able to just run out my thoughts and musings onto the Internet like this is really amazing. (From the command line via `toot` -- I don't need to spin up a whole Web browser to do it!) #SmallComputing

Either way, I'll take that advice and just rm this config file.......

Sometimes on #Linux I'll have a trash/ folder in my /root/ directory.
However, on some of my systems, I find that they're symlinks to /dev/null... was past me telling future me something about hoarding ..? Lol. #Unix

I need to learn how to use #vim.

And to top it off, I composed this post on the command-line with `toot` >:]

To be fair to GNOME though, my setup wasn't perfectly stock, though GNOME tends to be a bit unreliable anyway... *but*, to be fair, I also had to compose my post twice due to toot discarding my message with an error since it was longer than 500 characters. So now that I'm back to being a "hacker", I now need to deal with those sort of problems :)

I finally reinstalled Sway #swaywm on my system. After having recessed into normal UIs for so long (no offense to "normal UI" users, just not made for me!), I'm finally back 😎
I find it so funny that after reinstalling sway, I didn't even need to close GNOME, it just crashed the next time I woke my computer up.
