You may be a very nice person but if you have no profile description, no posts, no profile pic (doesn't even have to be of you!), and follow a bazillion accounts, please don't follow me.

the best ones have belt drive with CVT because it's quieter, smoother, and doesn't gunk up your pant leg

I lived the first half of my childhood in Beaufort and have amazing friends and family there still. St. Helena Island (a short hop away) has an incredibly rich cultural history, full of the most wonderful and resilient humans you will ever meet.

Every shooting happens in someone's hometown.
This one happened in mine. It's terrifying and heartbreaking.

I really hope I'm reading this right. It would be the VERY BEST news I've heard since Dolly announced she was still alive (and the second-best news in a whole lot longer than that)

the answer to the trolley problem is not to pick who to sacrifice, it’s to dismantle the system that led to an unsafe trolley crossing.

if any part of your morality strategy involves picking a group to let die on a hill, throw the entire strategy out. it’s wrong.

In my remarks at UVA about AI & the environment, I said the next 10 years of AI energy policy, in data centers, power infrastructure, & society, will set the trajectory of costs and emissions, and who bears those costs and emissions, for the next few decades. We don't want to look back with regret.

FWIW. I am "anti" a campus that bans a safe, vital mode of transport, and any person who insists e-bikes are for people who can't pedal

@padremiguel.bksy.social I am on your side.

I wear a helmet. If and when I get smashed by a driver, odds are the only thing my helmet will do is maybe, just maybe, sway the responding cop into believing the crash wasn't my fault.

prohibited on campus entirely? or just in dorms?

if the former, that's completely bonkers

if the latter, there's a rationale but I hate it

If you feel yourself being drawn in by a vision of uncongested city streets, please come talk to me. I can help. Traffic Impact Assessment will charm you, exploit your fear of driving slowly, and then will STAB YOU RIGHT IN THE BACK.

It's ok though. You're worth saving.

I got not beef with people getting in touch with their spiritual selves, but please, people, #TIA is snake oil. Do not fall for it! Please read my paper and save yourselves from that false prophet, "congestion mitigation"

Reader, I can assure you there is nothing in my paper that would lead any reasonable (or honestly, any unreasonable) human to draw that citation from it.

I am increasingly baffled...and alarmed.

What is the value of citations--one of the primary ways academics are judged--if they are generated through #AI #slop?

#AcademicSky #Academia
screenshot of the paragraph in which my research on traffic impact assessment is cited. The text reads: "Adaptation is an effort to modify movement patterns to suit specific requirements, such as adjusting, changing, rearranging, revising, and adding variations. Meanwhile, origination is creating new movement patterns to suit certain situations or problems, such as designing, composing, building, creating, constructing, and creating something new (Combs, McDonald, and Leimenstoll 2023)."
