Today 2:57 PM
AC Alert: City of Berkeley:
Air Quality Index (AQI) has reached Unhealthy levels.

Limit outdoor exertion.

The poor air quality is due to smoke from an earlier fire along the Bay shoreline.

The fire is now under control, but the smoke is lingering. Do not call 911 for information.

Really interesting to see the dynamics of the smoke plume in Berkeley. Thought this map looked odd, but it tracks with the visible plume: it's rising over the fire, bay winds are pushing it due east, and it's dropping down as it cools. I can barely see the hills through the smoke. Still localized.

Moni is running for Berkeley city council here in district 1. Referring to the San Pablo plan as authoritarian and fascism is absurd, alarmist, and unproductive -- and false.

Also, camped with one of the most aggressive chipmunks I've encountered. Kept running under my tent fly. And kept climbing up into the underside of the car -- I was like, who do you think you are, a marmot?! If I opened the car door, it came running. 🐿️ I should have reported it 🤣

I sure hope the suggestions in the thread aren't the kind of tactics the Trust for Public Land & East Bay Regional Park District take. And from TPL, it sounds like they're not. I'm also pretty sure the area within the track is ~all wetlands. www.tpl.org/our-work/gol...

Text:
Both quartz and graphite can form in the same kinds of rocks, either entangled together or with graphite as an inclusion within quartz. This gradient most often in hydrothermal fluid. As the fluids cool, carbon precipitates out first as graphite with silica crystallizing into clear quartz crystals around it.

Money. Donate money, not goods. So many people like donating something concrete, like a can of food. But food banks can make that dollar go much, much further than you can. Berkeley Food Network: www.berkeleyfoodnetwork.org/get-involved... Alameda County Food Bank: www.accfb.org/give/

Argh. They are cutting concrete next door, with no effort to mitigate dust. Didn't look like the worker was wearing any breathing protection either. It's just a cloud of ground concrete fine particulates surrounding my windows. Grateful I have air filters.

I am always surprised about the fishing detritus I find out and about. But this must be at least 400ft of continuous fishing line! Except for the two hand-wound bundles, it was stretched out along the pavement for ~150ft, in a manner suggesting someone unspooled it & then left it ☹️

I guess my biggest Takeaway is that there is no software or curriculum that you can purchase they can do anything better than well trained teachers. Invest the time and money needed to help Ts understand how students learn subjects and how to teach them those subjects and you will see improvement.

Conversion therapy is probably the only thing I have completely lost my cool with strangers about: several years ago I was in line to enter the statehouse to go to a totally different hearing, and got stuck in a huge group of pro-conversion folks 🤬 It's abuse at any age, and causes lifelong harm.

I was grocery shopping and saw an item I buy regularly for an unusually low price. But something felt off when I picked it up. And sure enough, it was the same packaging and container size, but had gone from 11.5oz down to 9 oz. 🤦‍♂️

I haven't used bikelink lockers in years, and I'm glad no one was around to witness my chaos today. First, it took me trying three different payment options: Bikelink card? Fail. Clipper card? Fail. Finally the app worked. Then my bike *barely* fit, took an awkward amount of moving & rearranging 🤦‍♂️

Lol Fat Bear week influencing vocabulary learning, love it! 🐻🧑‍🏫

Merriam-Webster

'Rotund'
The adjective rotund is a Word of the Week this week, owing to Fat Bear Week.

"After a summer spent packing away sockeye salmon, Alaska's heftiest brown bears are ready to throw their weight around. Online voting began Tuesday for Fat Bear Week, the annual contest that pits the rotund residents of Katmai National Park and Preserve against each other for the title ..."
- Associated Press, 22 Sept. 2026

We define the relevant sense of rotund as a synonym of chubby meaning "notably plump." The word comes from the Latin adjective rotundus, which is thought to share an older ancestor with rota, the Latin
