I also highly recommend shopping around for alternative RP2040-based dev boards. The official Pi Pico is surprisingly bad, and just about every alternative out there is better in one way or another. I mean, come on: no reset, huge form factor, only 2Mbit flash, micro USB - in 2024? Just about the only pro it has is that it is widely available.

Given the incompetence in hardware design with nearly every Pi ever released, I'm not sure why anyone would be surprised that the official Pico board is terrible as well. I mean come on, how do you fuck up USB-PD that badly? Unless you're doing it on purpose to force people to buy special power supplies sold by your vendors...

This and the shitty HDMI connectors.

You're right, people do use it neutrally in greetings, not just maybe. And in more than greetings, more as a general form of address. More specifically, I would say that when not used to address multiple people in the second person (i.e. when saying "you guys"), then the word "guy" implies that the referent is male.

Except for idioms like "I've got a guy" where you just mean you've got someone in mind. And that's where I was coming from with "silicon guy" or "hardware guy", "software guy" etc. Just as generic terms for your goto person in those fields, no gender implied.

I hadn't heard anyone use the word "guy" like that before now, and didn't know the word was used like that, so I wasn't thinking of those cases. If you said "I've got a guy" or "software guy" I'd assume you meant you had someone in mind who's a guy, i.e., male. I believe you, though. This might be something that differs regionally.

You don't even need the 8 :), 4 quadrature inputs will fit on one PIO block. Some lovely person got a quadrature decoder into 24 instructions, so you can potentially still do something useful on the same PIO block if you only need one or two quadrature encoders.

I mean yeah one block is 8 units right? Two pins per encoder which both need a unit each.

4 units per block, 2 blocks per RP2040.
