if you haven't done trail work before - I strongly recommend it!!! the forest park conservancy is responsible for our trails being beautiful around Portland. All it takes is a single outing on unmaintained trails to viscerally feel how much is lost when trail work falls to the wayside
In case you missed it: there's going to be a free shuttle to Forest Park this summer! FPC will be hosting free events this summer like forest yoga, painting, bilingual hikes, and more. Want to join us? Take the shuttle and we will see you on the trails! forestparkconservancy.org/get-involved...
my futurelock talk from #tokioconf is up! check it out, enjoy the story of a nightmare bug we saw at @oxide.computer

working for polymarket should be understood as loosely morally equivalent to, like, being paid to sell heroin (and nothing else) to 8 year olds (and nobody else)
Crazy crazy story. Times of Israel reporter ( English language Israeli news site ) gets escalating death threats to change story that’s at center of big polymarket bet. www.timesofisrael.com/gamblers-try...
- CDC marks 95% population vaccination rate as "enough for herd immunity" - National vaccination rate for kindergartners is 92% - Oregon kindergartners have a 90% vaccination rate, and the vaccination rate has been falling every year for about that past decade
Officials say risk to vaccinated people is low.
Unfortunately, for: - Immunocompromised kids with cancer - Babies too young for MMR vaccines - The 3% of people for whom the vaccine has low efficacy, Officials say "get fucked"
Officials say risk to vaccinated people is low.
golang enthusiasts be like "check out our cute mascot" the mascot:
plan9/go enthusiasts really getting out of hand with the mascots these days
This is futurelock! - There is a future which needs to be polled to finish picking up a lock (it was granted a permit) - But no one is polling it, so progress cannot be made - and any other task waiting for this stuck future to complete will wait forever

hit a similar issue a few times, when I asked: - Please write a regression test first, check that it fails - Then write the fix Where claude will write an insufficient test, see that it passes, and move on happily. Such a straightforward mistake, but pretty bad if uncaught!
As someone who drives in SE PDX more than I bike, my goals are, in-order: 1. Don't murder anyone 2. Get where I'm going Making streets safer for cyclists helps me (and other drivers) do (1) without impeding (2). Bring back the planters!
Love how these advocates call the bluff on the dubious reasoning behind removing beloved diverter-lite planters: just bolt the damn things to the ground and keep it pushing.
Holman lane is one of my favorite hills in forest park. Yesterday I organized a little group run to go up and down it all day long. We raised a few hundred dollars for forest park conservancy! Perhaps I need to rally the runners for more hills repeat events soon 👀
> “Our fiscal system only works with immense growth,” says Mike Wilkerson, director of economic research at Portland-based ECOnorthwest. “That’s our economic strategy.” Not wrong, and choosing to ignore this will imperil way too many public services that we can't afford to lose.
This is a great explainer of the MultCo budget and how it's evolved this past 10 yrs. None of this should be surprising to anyone paying even a little bit of attention: there's a structural gap between revenue and expenses, and we spend a ton of money on social services. One more thing though...🧵1/x
Portland, estimating the cost of: bridges, schools, etc
The price tag to construct a new interstate bridge linking Washington and Oregon has doubled to $14.4 billion, officials from the two states said Tuesday. oregoncapitalchronicle.com/2026/03/17/r...

holy shit I found this on the street
Is the US also bombing elementary schools, vaporizing children, to stop them from making more soldiers? God damn this sucks
The U.S. is destroying Iran’s missiles and bombs to stop them from taking more lives.🧵👇🏼
Easy. Go for 100 miles. Do this backyard style: 1 beer, 1 taco, 4.1 miles every hour, for 24 hours straight.
have been discussing this prompt with the fellas for the last 12 hours so now i bring it here: do you think you can do this
Great story, with possibly the greatest author's disclosure of all time: "Disclosure: Prior to his election, the author was Councilor Green’s DM in a Dungeons & Dragons campaign."
ICE tear gassed a bunch of children on Saturday. This was a massive escalation of force. They were shooting tear gas at the back of the crowd, it took these unmasked people maybe 3-5 minutes in the cloud of tear gas to escape in without trampling. www.theverge.com/policy/87278...
people will use this as a pretense to fearmonger even though an average of 429 children are injured by manually operated vehicles every single day Waymo should absolutely be expected to analyze and prevent similar situations going forward, but human drivers are so dangerous
The child, whose age is not known, sustained minor injuries according to Waymo. The National Highway Traffic Safety Administration is investigating.
we should tax Waymo for presence in portland, and have outsized penalties for them for unsafe driving, resulting in compensation to the city/citizens. This could fund public transit options (trimet) I don't understand the pdx approach to ban technology, rather than force it to become a net good
You should know that Waymo wants to come to Portland. You should know I don’t support that.
This is a "Jane Jacob's" classic take, which would be one of the most significant ways to improve Portland. It's slightly counter-intuitive from a left political perspective, but this area (zoning) is one where I firmly believe reducing bureaucracy, mandates, & laws would be a game-changer
Here's what I'd tell Wilson if he asked today: 1) Let people share roofs, pipes & land if they want to...most notably, do @pnwelcome.bsky.social's Inner Eastside for All upzone portlandneighborswelcome.org/inner-eastsi...
the recent AI discourse has me feeling things, so it's still worth stating for the record: - AI as a "self-justified product" for end-users is usually shit - AI for tooling does not release you from responsibility of what is produced - You can (and should) still do things by hand, whenever you want
Rust devs doing weird things 🤝 everyone in Minneapolis and Portland "Wow fuck this ICE"
For Rust people interested in async code at TokioConf, I'll see y'all in April!
going to start using "do you think the merlin bird ID app is evil" as a litmus test before discussing technology with people
in college I took courses on machine learning. As a part of that, we built simple neural networks - from scratch - which could generate text, make classifications, etc. If you really hate AI, consider what the breaking point might be here. Do you truly hate the technology, or the way it's applied?
It's possible to be skeptical and concerned about AI companies (disinformation, neurosis, lack of critical thinking, job security, plagiarism) while also acknowledging usage patterns of the public. quote responses to this reinforce how correct @davidcrespo.bsky.social is about "bubble opinion"
this is a bluesky bubble opinion. 800M+ people use chatgpt every week. I hate Facebook and Instagram and I wish they didn’t exist, but 3B and 2B people use them every month, respectively. it’s very hard to picture a mass or even a niche left backlash against them
