I’m no longer active on Twitter. Find me at https://t.co/7aQwwJvJ8M on Bluesky, or https://t.co/OBqMibaaX3 on Mastodon. If I follow you here or know you personally, you can DM me for a Bluesky invitation code. (Sorry, don’t have enough invitation codes for people I don't know.)

Why are you still here? Come over to Bluesky 🦋

For what it’s worth, I’ve been enjoying Bluesky a lot, and I think they do a lot of things right (disclaimer: I’m an advisor to the Bluesky team). Mastodon is less well designed, but a lot of the academics seem to have ended up there, so I’m somewhat active there too.

I’ve been basically inactive on Twitter for 6 months, as I’ve become increasingly uncomfortable with the new owner’s endorsement of far-right extremism. It’s not something I wish to be associated with. I’ll keep the account up, to avoid breaking links, but I won’t check it either

Preparing for interview to FAANG / Working in FAANG

We are planning two events for the local-first community: • September 23 in St. Louis, MO, USA (after Strange Loop) • October 24 in Cascais, Portugal (at SPLASH) https://t.co/GKeaDpYHWH Submissions for Cascais are open; for St. Louis, please let me know if you want to attend!

I'll be speaking at @strangeloop_stl about our recent research on collaborative text editing. Sad that this will be the final Strange Loop!

Terrific work by @molly0xFFF @web3isgreat

One week remaining to register for our summer school if you're interested! More details now available on the website

This clever crow figured out how to pull up the bin bag and hold it with its claws so that it can reach the food inside. Seen today in Munich

New paper! 📄✨ It turns out that all text collaboration algorithms have an interleaving problem, and we fixed it for the first time. Very proud of this work with @MatthewWeidner3 and @josephgentle

Program of the PaPoC workshop looks great this year. Sad that I can't be there this time

Hi @Eurostar, is it ok to bring this type of pram (with bassinet) onto your trains? The frame is foldable but the bassinet is not. Not sure whether the bassinet will fit in the overhead compartment, and the website https://t.co/BdHQPL7Z5T is not clear on what counts as “folding”

Of course you might say that distributed systems really are witchcraft and you wouldn't be wrong…

Hilarious that someone who ordered a copy of my book could get a misprint in which the contents have been replaced with an encyclopedia of witchcraft. But also irritating that Amazon allows poorly printed counterfeit copies to be sold! https://t.co/GfUTjyASZt

📝 Really enjoyed the 'local-first' talk from @pvh and the perspective shift from the binary offline/online to a spectrum of latency: offline is just online but with extreme latency. https://t.co/UjYoUYlP2c

Pleased to announce that the application for the first Summer School on Distributed and Replicated Environments (DARE 2023) to be held at VUB on 11 - 15 September is open until 15 May 2023. See all details at

I’m co-organising a summer school on distributed systems for master’s and PhD students, along with @xmal, @anne_biene, Carla Ferreira, and @elisagboix. It will be in Brussels in September. Great opportunity to work with some leading researchers!

There are now over 150 published papers about CRDTs (let me know if any are missing). Feels like it’s becoming a real field of research!

One of the things I'm most excited for is partnering with the LibSQL folks to create a custom syntax for defining tables which are backed by CRDTs! LibSQL is truly getting SQLite ready for the coming decades -- https://t.co/A4xHXk1X2Z https://t.co/w63j5KxOPL
