#lazyweb 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).

I am making a Python dictionary with integer keys. Something, somewhere, went wrong in my life.

#lazyweb The hell is a three-way string split?

I thought a split of a string implied two parts- a before, and after :D!

Ugh I hate this error, especially the "introduces a 'static lifetime requirement" part. But Idk how to make it better.

Maybe "in order for TableDisplayInfo<'static> to implement Borrow<TableDisplayInfo<'a>>, 'a must live as long as 'static".

What do you think, @ekuber?

Unlike what Wikipedia has to say on the subject, it's not clear to me that basic +1/-1 non-restoring dividers are a net win for hardware size or speed.

Seems like any size/speed wins by avoiding the restoring step are negated by the need for two different subtractions that need to be muxed per iteration. Also, the restoring step can be done in parallel in hardware.

Tbh, I thought it was 7 hubs. Did this change between 2.0 and 3.x?

@foone Hi Foone! Any chance you could pop onto IRC for a bit when you get the chance? Someone is requesting a skillset I know you have :D:

#lazyweb Anybody know a better way to print the size that all files (and directory entries, BUT NOT DIRECTORY CONTENTS) take up in a directory besides, e.g.:

ls -lh path/to/dir | head -n 1

(The above does what I want, just feels like there should be a better way...)

Tried a Hot Pocket in the air fryer... how the hell did I live without this?

This is a bit time sensitive, but... feel free to RT.

I'm looking for a bit of paid work (low to mid hundreds of USD) before year's end.

Most comfortable with embedded Rust and FPGA design using Amaranth HDL.

Small things I can think of include porting your board to Amaranth, getting you started with embedded Rust, or getting you started with verification tools with yosys-smtbmc and symbiyosys. I am willing to write C as well.

I had this on my Amazon list. It's a 35mm DIN rail terminal. I have no idea how/where this got on my list.

Now I'm going down a rabbit hole of "uses of DIN rails".

I did it. Phase 2/4 of my little project complete. Not ready to announce yet, but it feels nice to get it working.

Dial up standards seem infinitely more f***ed up than the contemporaneous Ethernet standards at the time.

How do/did ppl grok them? Hell, how do/did ppl grok POTS. Even POTS seems utterly intractable to me.

I'm so happy F-Zero is getting love.

I'm not sure I've heard a single bad thing about F-Zero 99. It almost makes me want to buy a Switch/get a online subscription.

But, I'll stick to watching. I can play the SNES version at any time:

I think I found a gentle explanation to NFTs and why they're silly. How's this?

"ou know how copying computer files is cheap? I.e. "You wouldn't Download A Car", "Don't Copy That Floppy", etc. NFTs are meant to be a way to enforce "I own this pattern of bytes, you can't copy it, otherwise there will be consequences".

There are no consequences in practice, b/c most ppl don't take NFTs seriously. They inherently take a lot of energy to compute ownership, and are VERY bad environmentally.

LRT: At this point, I don't think it's conspiracy theory territory that web standards were deliberately engineered to be unimplementable by a small group, a power grab for Big G.

Is Analogue still doing their "it's FPGA therefore it's not emulation" schtick?

TIL (ty @whitequark) that if you press "y" on any Github repository page, you'll convert it to a permanent link based on the current commit hash ._.

I needed this functionality like 5 years ago... :o

After 3.5 years (!!), I am proud to announce that I've written a new blog post on my site:

"Using z3 To Solve Logic Puzzles"

z3 is an SMT solver; this post also serves as a whirlwind introduction to SAT and SMT problems. So if you've heard about SAT/SMT, but don't know how they work, give my post a read!

I hope you all enjoy, and would love to hear feedback:

Someone on Fedi has a PCB protoboard generator they showed off recently, but I can't remember who.
