General request: if you post pictures, please please include alt text describing the image so that everyone, regardless of visual ability, can enjoy your toot.

Please consider asking others to do this. Optionally, reconsider boosting toots if they don't have alt text.

We all have an opportunity to help shape the culture of this place and I'd love, love, love if it were "oh, everyone posts alt text with their images because that's just what you do."

Did you know that you don't need to use link shorteners (bit.ly, etc.) on Mastodon? All links, no matter how long, only count for 23 characters against your 500 limit!

(And since link shorteners are bad for user experience and break the web, there's almost no good reason to use 'em! 😄)

Please consider writing your hashtags in upper camelcase so screen readers have a chance at figuring them out.

#whyistayonmastodon sounds like an giant undecipherable mess of sounds.

#WhyIStayOnMastodon reads out "Why I Stay On Mastodon" 😄

(Reason #44 I stay here: my previous requests like this have been generally well-received, proving that most people are awesome.)

AWOO FINE

USART has "separately programmable assert and deassert timers" in hardware

timers max out at 2 bits (of a character)

Protocol has 1.5 char (12 bits) of allowable inter-char interval 😞

Back to software driver assert!

Those three little words I need to hear

Oops. Forgot to post my #coffeeneuring ride from Friday. The challenge states "7 different places" and I hated to burn the actual *coffee shop* itself so early, but it was a rare day off work and the weather was perfect for a long Parkway loop. Tons of climbing but unspeakably nice weather.

#coffeeneuring solo trip today up to Tuggles Gap. Stuck to the gravel backroads since the Parkway is packed with leaf-peepers. It was warm enough in the sun that my thermos of Red Rooster coffee was too hot to drink when I got there. 😀

Huh. The entire DBGMCU block up at 0x5C001000 reads zero. I wonder if this is some accidental interaction with their ST-LINK implementation.

Fun embedded discovery: NUCLEO-H743ZI2 board mistakenly reports its device ID / revision ID register (DBGMCU->IDCODE) as zero. Given the shenanigans with silicon changes between rev Y and rev V, you'd think they would've worked on this. :(

(One has to compute clock dividers differently because they goofed up the ADC implementation. The practical approach for bootloaded products is to sense at runtime and insert the *2 and the extra BOOST bits as needed.)

At the back of the cabinet is a leeeeetle bottle of B&B. I don't know who left it here or how old it is; close to a decade, perhaps? It's been a long time since we had the sort of parties where people would bring liqueur.

So of course I had to pour a glass of it. Sometimes you have to take a swig of the abyss and see what comes back.

Hmm. This is going to be a different kind of challenge in Floyd County this year. There's precisely one coffee shop open in the county and it's only open during my normal work hours.

#coffeeneuring starts this upcoming weekend. Seven drinks in seven weeks: an excuse to slow down from the randonneuring and big adventure spirit of the summer, to take a cup of coffee or hot chocolate or tea, sit upon an old stone bridge, and enjoy the autumn. 🚴☕🌳
