Another important fact about me is that I collect ISA cards. I still don't believe in magic- just concepts I don't understand yet.

Okay, the CI hell is over. I have released the first version of my "switch your monitor inputs from your computer" program. It even comes with a GUI :D:

Hopefully you'll save a few minutes of your life over the course of a few years :).

thermostat controlling the boiler for heating here over RF: broke a week or two ago

flipper zero that i've been using to manually enable the boiler instead: also broke somehow

me: freezing to hell and beyond due to it being 5°C outside and not having anything warm

my headmate: spends four hours putting together this incredibly normal setup using her beaglebone and a radio carrier module she designed a year ago. she even got the RF modulation parameters right on the first try, wtf

I don't love that the "1.44" in "1.44 MB" floppy isn't actually either "Megabyte" or "Mebibyte", but rather it's 1.44 "thousand Kibibytes".

@mcc 1.44 @foone 's

1 Foone == 1440 kibibytes

@tubetime I and O too easy to confuse with 1 and 0?

I feel like I've seen this before in e.g. Game Genie codes.

@whitequark I love the implication that "why is it bad" is self-explanatory from looking at it :D.

Rust's "Cargo" has a feature named "Features" and a feature named "Examples" and there is a feature where an Example can use a Feature and this is incredibly, incredibly hard to google for. So far I've got as far as finding examples of Features, but not as far as finding examples of Features of Examples.

cr1901,
@cr1901@mastodon.social avatar

@onelson @mcc cargo's features are the Rust equivalent of "cc -DMY_EXTRA_FUNCTIONALITY".

Cargo also provides a built-in mechanism to run code examples for your library (called, "examples" :P).

These can be combined, so that a code example requires a cargo feature to be enabled if you want to compile/run that example.

Memory errors in consumer devices such as PCs and phones are not something you hear much about, yet they are probably one of the most common ways these machines fail.

I'll use this thread to explain how this happens, how it affects you and what you can do about it. But I'll also talk about how the industry failed to address it and how we must force them to, for the sake of sustainability. 🧵 1/17

cr1901,
@cr1901@mastodon.social avatar

@gabrielesvelto Really depressing that we've reached the physical limits of creating "memory we're confident that actually will store it's value reliably" :(.

We've went from PARITY CHECK 1/2 to "memory works fine without detection or correction" to "oh now not even parity check is enough". In that sense, it's WORSE than 40 years ago :P.

@whitequark Dunno if most obscure, and def not good, but I've been holding onto this one for a while.

I want to create a railroad-themed OCaml fork. Each toolchain installation will be called a switcher.

All of the open ECP5 tooling work is cool and all, but a little on the small/slow side for my taste.

Is anyone working on open tools for Lattice Avant-X yet?

> 85000 LUTs

While I agree that's a medium-small to medium (at best) FPGA in the grand scheme of things, I still wince a bit :P.

@mcc I like Lattice Reveal. But maybe that's because I've legitimately used it to solve a problem before lol (it also mostly "just works").

I need a used-working NVMe SSD (2280). Anyone have an one they'd be willing to part with for the cost of shipping (plus a convenience fee)? 1TB preferred, but I'm fine with any size.

I'm looking to do all this under $15.

It's fine if it's used because I want to test if my 2017 desktop supports NVMe (and the answer seems to be... possibly... not even Acer seems to be sure).

cr1901,
@cr1901@mastodon.social avatar

@foone Will do, tyvm.

Fun fact, you gave me old RAM for my 29+2 Bday, and I potentially get a test SSD for my 29+5 Bday :D. So thanks again <3.

Btw, that RAM is still going strong. Am typing on the machine it's on rn; it's the reason I've gotten to 12+ years with it :D.
