amen www.jmduke.com/posts/beset....

as someone who uses llms, i'm totally fine, even happy, about lobste.rs being an anti-llm space. if you want pro-llm stuff you can look anywhere else on the internet. if we want a moderate sort-of-llm community we can create one. niche communities with hardcore value systems are good.

placemark.io supports sharing maps again. this time, using atproto. try it out! let me know what you think!

tempted to make macwright.com "more accessible for llms" but struggling to figure out a single way in which doing so benefits me

llms could never produce this product-description prose

The ecosystem between humans and technology is imbalanced. Platforms reap benefits of attention, at the expense of emotional well-being. For #MozFest, I propose Emotional Mutualism, a philosophy & practice towards designing emotional symbiosis with tech. lindsayjferris.substack.com/p/emotional-...

I built an implementation of the TC39 structs proposal that you can use today: `struct` and `shared struct`, Atomics.Mutex and Atomics.Condition, and objects that really are shared between workers. A compiler and a runtime, on npm as @arv/structs. structs.arv.tools

'you can see everything' is the best movie i've seen in 2026, you must see it

Hi! For the past few months I've been building a vector drawing app, because the existing ones either don't work for me, use deceptive subscription models, or both. The app is called Superlinea, and I've started a newsletter to share progress as I develop it & announce the release: superlinea.app

deno made high quality software that moved the state of the art forward and had an incredibly talent-dense team

Today is ICANN Reveal Day! 1,615 strings: .agent, .api, .agi, .ask, .auth, .bad, .bro, ... 481 applicants: Google, Amazon, Meta, Microsoft, OpenAI, Anthropic, Cloudflare, Vercel, Squarespace, Airbnb, ... Gonna thread observations until I run out of steam

last night's sketch (very heavily inspired by @cloudhead.io)

A year ago, @propublica.org told you immigration agents had detained more than 170 U.S. citizens. We’ve updated our count, and we’ve got all the receipts. The tally: At least 506 citizens detained. Sometimes held at gunpoint, handcuffed, or even deported. projects.propublica.org/american-cit...

hire erica, one of the smartest people in the biz.

just goin about my day citing a photo from wikipedia for a blog post and it's from @enf.bsky.social, it isn't even sf-related, it's nyc! some people have made such an impact on the internet i just land on their name over and over.

Did you know leaflet has a canvas? We recently got a bit carried a way and added a LOT to it. You can now: - DRAW! - add canvas pages to your publication - set view areas for mobile - make canvas images in posts - try it out at leaflet.pub/new-canvas check out this video for the full run down:

tempted to make my website's design 'weirder' because websites are getting too normal. might do the csszengarden thing and do multiple layouts with just the power of Modern CSS.

I'm very please to announce a public release of my drag-and-drop bookmarking, game-making, and wandering tool Scrubjay! Scrubjay is a weird website builder that lets you cobble together web elements, images, links, text fragments, etc into a series of nested rooms...

I think students should read full books.

You can now create and manage teams in the new Observable, use Opus 5.5, connect to MySQL… but, most exciting, and by far the most overdue: you can now access SQL cells’ metadata fields by opening the cell menu with ⌃M. Keep those hands on that keyboard! observablehq.com/@observableh...

nowadays it's hard to know whether i should follow the ai accelerationism of ashton kutcher or joseph gordon-levitt's safety fears

i'm very happy that placemark is now on maplibre / however, it's sad not to get the huge perf boosts that @agafonkin.com delivers for mapbox-gl-js, few in the industry are on this level github.com/mapbox/geojs...

I wrote about what I've been up to with my new programming language! Zena targets WebAssembly GC, with a TypeScript-like syntax, sound type system, and lots of cool features like pattern matching, async cancellation, borrow checking, WASI integration, and more! justinfagnani.com/2026/09/09/z...

i know it's not their market but "an oxide rack but with big honkin gpus" seems like an inevitability

cycling nyc is so delightful, covered new ground on randall's island and rode the high bridge this weekend

observable's community is just stacked with talent

i applaud togo on promoting the equal earth projection, but as a pseudo-cartographer i have to note that the earth is in fact round, not flat, and quite a lot larger than this

For more than a year, we’ve been quietly building an all-new Observable. Today, that new Observable is live on observablehq.com. Read Mike @ocks.org’s announcement: observablehq.com/@observableh...

don't go anywhere near my lakehouse bro, it's swarming with agents

it's good, you should read it

my favorite bogus security report goes like "your application does X. and mind you, it does it correctly. but if it _didn't_ do it correctly, that'd be a security problem!"

on a fun project bugs are fun too

Flavors used to be infused but nowadays flavors are blasted. This is happening to society as well of course

it continues to fascinate me that of all the custom big corporation fonts, the one that has the most flavor is from ibm

Placemark is now _fully_ open source, thanks to @bskyum.bsky.social macwright.com/2026/08/25/p...

the protocol labs narrative is starting to solidify into it having been a very spendy labs project that ultimately benefited atproto and iroh instead of its own projects ipshipyard.com/blog/2026-th...
