I move factors over from the 24 to the 15: 15 x 24 = 15 x 6 x 4 = 90 x 4 = 360. Seeing a nice result I double-check with an angle I know: 15 x 24 = 15 x 3 x 8 = 45 x 8 and 45 degrees is indeed an eighth of a whole circle!

Flag-raising for Leiden Pride! About the right level of Pride intensity for our household of queer introverts.
Gentrification is what we call it when demand exceeds supply. It is not caused by bike lanes. The answer is not to suppress demand by enshittifying cities, or to justify endangering & killing people outside of cars as a rent control mechanism, but to increase supply.
A few months ago someone on social media offered the best question to ask yourself when doing a purge: if it had poop on it, would you clean it or get rid of it? 🤣 It made my spring cleaning purge so easy 🤓
here’s a version where the POV is blacked out whenever the driver takes their eyes off the road
The thing is, every time you defend Newsom as a great candidate and what “we” need, you’re telling trans people that you’re willing to throw them under the bus You can sit in my mentions and whine about how I’m criticizing Newsom too much and I will continue to highlight how your transphobia sucks
Happy Birthday! Congratulations on making the cupcake happen and I'm sorry the taste test will have to be another time.
time to email your governor and tell them to step TF up regarding vaccines
I think the biggest hint may have been the personality... I didn't see it coming though.
Thanks for the recommendation!
Hive mind: Where do you go to get photos printed (or where do you order prints from online)? I used to use Target, Walgreens, or CVS, but the quality got so bad it wasn't even worth the few cents per print. (Plus I haven't shopped at Target since the boycott started.)
One of the most successful pedestrian streets in the world, the Strøget in Copenhagen, was filled with cars until a 2 year pedestrianization pilot project in 1962. The opposition argued “no cars means no business,” but the street has been a massive retail success, the city’s busiest shopping street.
“Over the past 20 years, Paris has undergone a major physical transformation, trading automotive arteries for bike lanes, adding green spaces and eliminating 50,000 parking spaces. Part of the payoff has been invisible — in the air itself.” Leadership, strategy, real action, common sense. #Paris

For no particular reason, we're thinking of cafe locks... those simple locks one finds on most Dutch bicycles where the keys stay in when its unlocked so you don't lose them.

This sounds right up my alley, but I tried The Poppy War and had to bounce because I just couldn’t with the unrelenting horrors of war. Does anyone know, is this lighter/less grim?
The last of the completed North Shields 800 murals, “Spirit of Shields” at North Shields FC’s stadium, by Mark One87, who worked with local Phoenix Detached Youth Project to workshop and prepare the mural wall. More here: ilovenorthshields.com/elevation-mu... Two more murals to come, I think.
I took this picture myself at the CDC protest today. These are among the hundreds of bullet holes in CDC headquarters windows, visible from the street. I heard today that the admin has no urgent plan to fix these windows. Imagine being a CDC employee going to work under these conditions

You guys. Have you seen that many countries are no longer delivering mail to the US? www.msn.com/en-us/money/... Including NL. 😭
This is also my stance.
"For any" is another one that people have strong conflicting opinions about!

Thank you!
Hey #BikeSky, does anyone have a short op-ed on a biking-related topic that you think first-year college students should read? @clarabiesel.bsky.social

The first thing everyone in this country who is anti-fascist can do now is to join something where people are already gathering to address any issue. Can't find anything you want to join, then make your own thing and invite people to join you. This is not a time for Lone Rangers.

Noooo! I'm so sorry.
I love the state fair & I love this @streets.mn article by @blindeke.bsky.social from 2018 streets.mn/2018/08/27/s...
The timing logic seems to be "It's too unsafe to let bikes go whenever anyone else has a green, so the bikes have to get their own phase. But that would slow everyone else down so the bike phase only lasts two seconds." Somehow that doesn't apply to simultaneous car greens and ped walk signs.
We have signals like these on the main bike route downtown. It's frustrating because the bike signals don't even activate every cycle, so you have to hope the sensor can see you (it usually doesn't).

One of my biggest takeaways from the past year is a trio of observations that together make a coping mechanism I feel good about: 1. Taking action feels so much better than looking away. 2. Even small acts of resistance stave off helplessness. 3. Small actions make bigger actions easier.

It's not too late to make a difference! This school year I'm starting a bike bus with a few other families who live nearby, hoping to coordinate more soon.
My university just announced a campus event called "Overview of GenAI and Its Current Climate." The schedule includes some useful-sounding local info, but the keynote speaker is the author of this scholarly work of unmitigated #AIHype : papers.ssrn.com/sol3/papers.... Should I go? Advice welcome.
THE main reason it took me so long to get mental health help was that on days I had the wherewithal to take steps toward said help, I was like "Look, I can do stuff, so it can't be that bad." Not that that's where you are, just that I've experienced one piece of me accusing another of exaggerating.
"Plastic...is very difficult to avoid. But we are at a moment with "AI" where things aren't so deeply integrated, though corporate interests are pushing for them to be...every act of refusal is especially powerful & meaningful now..." @emilymbender.bsky.social buttondown.com/maiht3k/arch...
My bicycle was just stolen in Capitol Hill Seattle. Please keep an eye out for a small sized Salsa Vaya, green bicycle with a rear rack, steel fenders, dynamo hubs, 26” wheels. Parked at a bike rack at 15th and Pike. Saw my lock cut and thrown on the ground.
i want to believe… …that the ai bubble is finally bursting
To me one of the missing pieces is still how much energy/water a query uses if you add in the model training, averaged out over the lifetime of the model (maybe the number of queries in a year, given how frequently these companies are coming out with newer models).
I'd like to take this time to spotlight some critiques I have of solarpunk that aren't just misunderstanding what it is. I think a big problem we have beyond the lack of popular media (which may be a blessing) is the lack of certain voices. There is quite a bit of diversity but we need more.

Last day to do this, transportation advocates!
Seriously! Just imagine how much more cuteness would be in all our lives if public spaces were child-friendly!
Not to mention it sets up oppressed groups to be targeted. I've heard many stories of Black drivers being ticketed for going 1mph over the speed limit — how does that make sense in context of the 85% rule?
My hot take is it is corrosive to the fabric of society for it to be normal and even expected to regularly and blatantly break the law
NEWS: 40-year-old veteran & oysterman Graham Platner demands corporations pay for climate change. He believes the US should fund universal healthcare instead of endless war. And he says the genocide in Gaza is the “ultimate moral test of our time.” And he's running to beat Susan Collins in Maine.
All this talk about how infodumping is a neurodivergent trait—listen, we grew up reading SFF in the Nineties, OF COURSE we infodump. Y’all are lucky we’re not a full on italicized prologue.
Take a minute to respond to the DOT about funding priorities. The Secretary of Transportation said: “I do think it’s a problem when we’re making massive investments in bike lanes at the expense of vehicles,” ttps://bikeleague.org/the-u-s-department-of-transportation-wants-to-hear-from-you/
Also remember that the best indicator of how you’ll commute tomorrow is how you commute today. Start the term with new habits. Fresh starts are the best time to form new habits. Especially if starting at a new school. @ianwalker.bsky.social taught me that.
FWIW, I am neither a kpop person (yet?) nor a demon hunter person (probably ever) and I loved it.
Interesting article by Sarah Hall. Agree we need stories about the #climateandnatureemergency with hopeful outcomes (without denying the seriousness of the situation) I’m enjoying addressing this challenge in the novel I’m writing #booksky #writingcommunity www.theguardian.com/books/2025/a...

One of the things I find super interesting is the decision to move the characters at half the framerate of the animation, giving them that slightly choppy, comic book feel. But not everything (or everyone?!) gets this treatment, and it's so subtle I haven't yet figured out where all it's applied.

I understand duolngo is AI-bad. I am bad at making myself do things, and that green owl has kept me learning, slowly but regularly, for two and a half years now. Any suggestions that 1) don't need willpower 2) teach Catalan? I'm okay with paying versions.

St. Paul folks (+ anyone who bikes in/through St. Paul): An Open House for the Earl Street Reconstruction is being held on August 21st between 4-6 at the East Side YMCA. Please spread the word and join if you can to tell the city that we need off street paths (not painted bike lanes)!
Here you go! I'll write some new ones for this semester too. They loved them. The "read without your phone or screens in the room" was a revelation, and many of them decided to keep doing it. They had NO IDEA (& were horrified) how often they interrupt themselves to look at a phone for no reason.
![Reading Scenario Experiments. This series of prompts is designed to get you thinking about how the setting for reading affects concentration, comprehension, and even the existential experience of reading. Every week, one of the following prompts will appear on the syllabus. I encourage you to try all of them that you are able. How does a different reading setting affect your mood? Your receptiveness to the prose? Your pleasure or difficulty reading? What are the particular impacts of changing your lighting or surroundings? What do you notice about yourself and about the work you are reading during this experiment? 1. read by candlelight (use a small lamp in dorms where no candles are allowed!) 2. read for one hour without checking any devices, answering texts, etc. 3. walk out into nature (climb a tree, sit on a rock, grab a spot in a hammock) and read 4. host a reading night with friends & food (sit in companionable silence, reading without chatting) 5. read aloud a chapter to someone else 6. climb into bed at night and read by flashlight under the covers for at least 30 minutes, as if you’ve already been told “lights out” as a kid 7. reread a chapter and see what new things you notice the second time through 8. change your ambient-noise level: add music if you normally read in the quiet; or read without music if you are normally a music-listener 9. read with a sketchpad at hand and sketch scenes, characters, or other elements from the story 10. practice focused listening: have someone read to you 11. make yourself a special, fancy snack on a real plate to nibble while eating: pay attention to the cooking or arranging or choosing of ingredients to make it especially appetizing first 12. make tea (even if you’re not usually a tea drinker), and read and sip 13. invent a new reading scenario for yourself, or repeat the one you liked the best from this term [writing assignment using these prompts follows; text character limit prevents inclusion of it in full]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:rfs7afx6ue4mknbhhpnrzkyz/bafkreiel77b25truczj372qokmg5p3apa2dphux3jtplpz3dv35jul6wdu@jpeg "Click to view full size")
Did you know that you can weigh in *right now* on what our next big federal transportation bill should look like? You've got until August 20 — and if you're struggling to figure out what to say, these orgs have some great ideas you're welcome to steal.
need people to understand that accepting or conceding that he has the authority to do these things is tantamount to giving him the authority, and so your preemptive dooming is actively counterproductive
Announcing: My new book UNLOCKING JUSTICE arrives in the first half of 2026! It confronts America's unfair criminal legal system with data and humanity, showing how data science can drive racial justice. I wrote it to be optimistic + accessible to a broad public audience. Info + preorder updates ⬇️.
I'm going to see it in the movie theater next weekend! It's a sing-along showing and I'm so stoked.
Heads up library workers, Overdrive is shoving AI into Libby. It will be making book recommendations and they are rolling it out over the next few weeks. Smoke is pouring out of my ears. 📚
I've seen people say things like "our troops weren't designed to be used on US!!!" and look, I totally understand, I agree in some ways, but I really, really hope that if you feel that way you spend time thinking about the fact that there's no such thing as a weapon that can't be pointed at you.

Here's a photo of me from when I visited Minneapolis earlier this summer. I happened to come across the same style bus shelter, and wearing the same shirt, as in my profile picture. Please pardon my facial expression; I seem to have gotten worse at selfies since 2022.
Google just offered without prompting to do my math homework for me. (Just tested it out, and the "help" involves providing the answer).
I'm back in NL now visiting friends, and it's astonishing how backwards the US system is in comparison. It's a huge hassle even to pay back our friends for shared expenses — a trivial task if you're used to just giving someone your bank account number to make a transfer!
Only kid is still a bit young, so I'm singing it on the bike when I don't think I'd bother anyone :) Also @clarabiesel.bsky.social and @ktmulvaney.bsky.social and I are learning the three-part harmony for "What It Sounds Like" (because the melody alone is not that interesting!)
Does it count as owning it if I have it playing in my head constantly?
I'm so sorry
