Fascinating how the human body is so intertwined with the sun, from skin pigment attenuation for vitamin D3 production, to the evolution of circadian rhythms around light/dark cycles, and pupillary light reflex in response to low/high light conditions. Yes I’m extremely jet lagged, why do you ask?

Hello from Gothenburg, where they are not shy about taking away space from cars and using quarried cobblestone rock for drive lanes but not bike lanes.

Ok after staying in an *extremely* transit and bike oriented city for a week, I am now 100% convinced that excellent transit and bike infrastructure alone is not enough. Speed bumps, road diets, parking elimination, with the express goal of making it hard to drive. It’s the only way.

If you’ve ever wondered what surfing in the middle of a city looked like, wonder no longer. Some random canal in the English Gardens in Munich:

Hello from Germany, where they block the sidewalk not the bike lane 😬

An elderly lady pushing a grocery cart was struck by a driver speeding on Hearst this morning. Absolutely tragic what we subject our citizens to, and what we are all subject to. www.berkeleyscanner.com/2026/04/29/t...

Passenger vehicles are responsible for 35% of California’s GHG Emissions. Even if we switch to 100% green electricity, that’s a drop in the bucket compared to the impact of cars.

My Tom Flood inspired newsflash: “Don’t take away my parking for a bike lane!” Says homeowner with two car garage and driveway.

ChatGPT define the arrogance of space: A spring market popup in the space of some 25 parking spots.

Pedestrian friendly (car free) spaces are good for democracy

🚨Hopkins Street🚨 With an important Council committee vote coming on April 15, it's time, yet again, to speak up for pedestrian🚶‍♀️, bicycle 🚲, and transit 🚌 improvements on Hopkins! Take action👇 actionnetwork.org/letters/make...

2 step solution for super commuters into SF who are “hurting at the pump”: Step 1: Walk/bike/drive to nearest train station Step 2: Get on train youtu.be/B3gZts9iBSs?...

AVs are “innovative” in the same way that cigarette filters were innovative.

“Real potential for the strongest El Niño event in 140 years”, “Due to the increasing concentration of greenhouse gases…” Do I feel bad about your high gas prices? No. No I do not. apple.news/ARRNI6j_OQ9i...

A gas saving tip that everyone hates but is 100% effective and accessible for anyone who drives is "go slower"

SF’s overwhelmingly popular Sunset night market drew 20k people over 7 blocks. So of course drivers and some businesses threw a fit and they ended up scaling it back to 5 blocks. www.kqed.org/arts/1398562...

Overheard in SF: “We just did a hard pivot in our seed round”, “We are now called HumanAgent. We rent humans via MCP” 🤯

Total cost of CAHSR from SF to LA is estimated *today* to cost $231B. There must be a middle ground between “quarter trillion dollar moonshot” and “once a day 13 hour scenic service for retirees”.

I’d love see more headlines on LNG and fertilizer prices since those are much more impactful to developing nations. The west has many tools to blunt the impacts of oil prices already.

Whatever happened to the hacktivist group Anonymous? Because this would be a great time to help stop this heinous stuff.

The reasons why these horrendous PSA’s exist start to become clear once you realize these agencies believe the streets, as designed, are the state of the art. So death and injury is simply a matter of user error. Nothing to change, nothing to consider otherwise.

I actually love the vision and goals behind California Forever. All the unanswered questions and obstacles aside (Nepa/Ceqa, Lafco, Suison city council approval), they will face the hard realities of California fire and building codes. www.volts.wtf/p/how-to-des...

How my new co-workers view me, as envisioned by ClaudeGPT. Not not accurate.

My “Why cops are proactive sometimes and other times not” theory: Policing is a job like any other. Clear evidence identifying a perpetrator, followed by a high profile arrest and contraband confiscation, reinforces the value of law enforcement in the eyes of the community (or so they think).

hi AI, do my taxes. No? Okthanks

The correct take is: everyone should buy an e-bike first and foremost. If they also need, can afford, *and can safely operate* a car, buy an EV, a small one preferably.

Big shoes to fill

I’ve seen more than my share of traffic fatality memorials, but after visiting the West Portal site commemorating this family, something profoundly sad took hold of me for the rest of the day. These tragedies are not one-offs. They are blaring alarms about where, how the next one will take place.

Peak “Not like that” performative environmentalism

Haven’t seen Sinners yet, but Michael B. Jordan’s heart wrenching, haunting performances in The Wire and Fruitvale Station were unforgettable. Well deserved.

STUDY: “Bicycle lanes reduce GHG emissions as effectively as highways create them.” “Investing in networks of protected bicycle lanes has significant potential to reduce GHG emissions, lower transport costs, prevent road fatalities, & improve quality of life for people in cities around the globe.”

High LDL’s be damned

Metaphor for the US job market:

Neighbors: “You touch my parking I’m voting trump” Neighbors on street sweeping day:

Our children deserve better than to be forced to huddle together on a pork chop island in the middle of a slip-lane, which the city refuses to close. Not to mention the exposure to tire, brake and exhaust pollution.

Hopkins Street is back, but the news isn’t good. A new proposal would pave the street without previously-approved bicycle and transit improvements. Learn more at our Hopkins Teach-In on Monday, March 9 at 7-8pm (virtual). Register: us02web.zoom.us/meeting/regi...

The irony here is that Berkeley and Albanys' "parallel bikeways" project's will be delivered on a faster cadence (construction in early 2027) than would have been possible otherwise. Also, these sections of SPA are being designed in a way as to not preclude bus/bike lanes in the future.

Legal status doesn’t matter: if you exceed ICE’s melanin threshold, you get snatched. It is ethnic cleansing. There is no other word for it. The news has shown you video of these often violent detentions. What you don’t see is what happens to these individuals after. I’ve had a front row seat. 7/

@bauerkahan.bsky.social how are decision makers in your district concerned enough about bike safety issues to support drastic state law changes, but not concerned enough to even pick up the phone & talk to reps from the org that's worked on East Bay bike safety issues for over 50 years?

Asymptotically approaching midnight in microsecond increments

Instant Mark Carney fan

Fuck you people. Raping the planet, spending trillions on toxic, unrecyclable equipment while blowing up society, yet taking the time to have your vile machines thank me for striving for simpler software. Just fuck you. Fuck you all. I can't remember the last time I was this angry.

San Diego simultaneously has the worst possible car oriented land use of the modern era, *and* one of the most solar-punk transit oriented college campuses in America.

I’m fairly optimistic about AI providing more upside than downside to society. But the “solve AGI, and we will solve everything else” talking point is not convincing. Since “everything else” is mostly politically constrained not technologically constrained.

That values the whole generative AI market at just under $16 billion in 2025. Those 11 US AI titans had a market capitalization in October 2022 of $8.24 trillion, suggesting that they accrued $15.9 trillion in 3 years... 1000 years of their 2025 revenue.

“Push some code real quick” is what a startup making the next AI powered blender would do

How it started. How it went.

Another day, another billionaire, maga, sacred-native-american-grounds-destroying, oil tycoon stops a bike lane, 5 years in the making.
