Systems engineer ("DevOps" if you're a recruiter), with a dash of audio engineer thrown in there for fun.

Sure, but what about performance per joule?

It's worth point out that on many microcontrollers (STM32's at least), configuring a pin as a "digital input" means that the signal is routed through a Schmitt trigger circuit that's built into the MCU.

This also means you'll want to ensure that any floating MCU pins are _not_ configured as digital inputs, as the Schmitt trigger circuit itself will waste power switching back and forth between high and low states constantly.

This is true, I just didn't want to admit it as someone who joined after 2015 but before 2021...

I would argue that Meta had already overhired by the beginning of 2021, and the hiring spree was continuing.

Probably Microcenter in Brooklyn is your best bet, but still limited selection. It really feels like there should be a hole-in-the-wall gaming PC shop in LES - maybe we should just open one?

Maybe not if one of those items is always in your backpack. A few other use cases that I think they're great for:

- Throw one in your checked bag when traveling

- Mount one in a relatively concealed location on your bike

- Keychain (depending on if you're prone to misplacing your keys)

Or just, I don’t know… package your software?

The fact that the Adafruit team continued that thread unabashedly after Paul Stoffregen's first reply is an awful look in my opinion. Doesn't seem like anyone here is behaving like adults.

Edit: I should clarify - Paul seems very much like a mature adult in all of this.

This comment shines a spotlight on my issues with the US auto market. None of these vehicles are sold in the US, for a variety of reasons - both economic and regulatory. I hate knowing that the vehicles I want to buy both exist and are affordable, but I just can’t have them. Meanwhile, the cars sold in my market are all egregiously enormous, have giant screens inside, etc.

This is the very definition of a “first world problem,” but it sure is frustrating.

My 2004 RX-8 had decently solid ESC, but it was a “high-end” vehicle at the time. It’s definitely something we want to keep in our idealized vehicle (but let’s also keep the “disable ESC so I can have fun” button)

What about if you’re hit at 10mph? Of course any crash at 55 is fatal for a cyclist, but most impacts with cyclists don’t occur at highway speeds.

That’s true, but Zen1 TDP is a lot higher than an RPi. Hitting that level of performance in a power and heat envelope that works for a Pi probably demands a smaller process node, unfortunately.

But you exit going faster, which means you make up time on the straight after the corner.

> Also the claimed "Rush to buy electric vehicles" put revenue only 2% above expectations?

The rush to buy electric vehicles was baked into the expectations, so beating by 2% is still noteworthy.
