My favorite feature of JMAP is that it gives you a single, consistent API endpoint that works for native clients, webmail and programmatic clients (like, backup scripts and things like that). JMAP means you don't have to invent your own REST API for webmail. Unfortunately, gmail, yahoo mail and all the rest predate JMAP. So it doesn't really help them in the same way.

It'd be lovely to get thunderbird working with JMAP!

How is it not actionable? "Hey, you seem keen on feature X but I don't care about that. Just maintain X in your own fork. Thanks!" -> Close issue / PR.

Is this an illegal move? I've done it plenty of times. And other people have said the same to me, too!

I've never heard of most of them. AAA Certificate Services? AC RAIZ FNMT-RCM? ACCVRAIZ1? Actalis? AffirmTrust? Even Godaddy is in there. I know I don't trust those guys.

Trust has gotta start somewhere. But its much better to TOFU, then pin signing keys in the updater.

I was delighted.

You barely need domain expertise any more. Just ask claude to make it go faster and it will.

I'm just saying its ok to ignore overly enthusiastic contributors and tell them to just fork your project.

I think this does help, actually. In my early days of maintaining opensource software I felt burdened by open PRs - like I was letting someone down by ignoring their work. "Its ok, let them do whatever in their own fork" is advice I wish someone had given me.

If someone really wants a feature in a project you wrote, but you don't care about the feature, just let them fork. Its fine.

They worked like that when I was in Paris ~3 years ago! At the time, people were rioting over the retirement age changes. I walked around the city the day after the protests. The city smelled like burned plastic. There were burned out rubbish bins and the husks of melted lime bikes & scooters all over the place.

I've never seen anything like it.

To me that sounds crazy! But, I can see how it works for the French. They protest all the time, and the government is very responsive to the needs of the people. Much more so than the American government sees to be.

I had an argument a few weeks ago because our page took 4 serial requests before content appeared. I argued - with solid data - that it should be 1. If we could manage that, cold load time would ~ halve.

Theres lots of open questions about the future of our profession in the age of AI. But, playing with opus and fable, I think the future will be bright for our users. There is no reason any more for teams to put out junk that’s worse than what an LLM can do.

Personally I much prefer Fastmail to Gmail. The site is way faster and more cohesively designed. Fastmail supports jmap, and way more imap extensions (including push support on Apple mail). They have helpful humans handling support requests. And they do all of that with what seems like 1/10th or less the number of employees.

The only thing I like more about Gmail is their native mobile apps. Fastmail’s official mobile app is a web view.

So far at least - and its been less than a day - Fable seems better at this.

I think I also do my CRDTs differently from others. I've grown to like the pure-oplog approach after making eg-walker. LLMs are much worse at this!

I’ve read plenty of papers with “formal proofs of correctness” that turned out to have huge flaws. Machine verifiable proofs I trust. But I’ve personally found more bugs with fuzzing than I have via proofs.

Fable is doing - so far - a great job. I just had one big question around how part of it should work. I had a design sketch, but with some big unknowns. I asked fable to figure it out via reasoning and prototyping, and it did - it even, under its own initiative, wrote a fuzzer for its prototype which explored and verified that its reasoning was correct. It absolutely nailed it. And it found, and fixed, a couple bugs that I'd missed.

I'm sure its weaknesses will become apparent in time. But, wow this thing is a beast. Its the first time I'm reading the work of an LLM without spotting obvious weaknesses in its reasoning and code. I'm really impressed.

I want Claude and OpenAI to be able to compete with Siri on an equal footing. Just like Apple maps has to compete with google maps. Competition pushes companies to make better products.
