Why is the two generals' problem is unsolvable? Because of the *imbalance of information*. It's counterintuitive, but the sender of a message always knows *less* than the receiver. youtu.be/MSU6coE1j8M?si…
Distributed systems is the most fun field of computer science because of the stories behind each concept. That's why I'm launching Distributed Systems Made Simple, a YouTube channel to tell these stories in a fun way while diving deep into the "why". youtube.com/@DSMadeSimple
TEEs need stronger rollback protection. ROLLBACCINE offers it – no app rewrites, minimal overhead. Learn how it works. #CCSummit #ConfidentialComputing #TEESecurity @opaquesys @davidchuyaya hubs.la/Q03lrbD80
New Blog Post! shadaj.me/writing/distri… I argue that we’re *still* lacking a programming model that’s native to distributed systems, and outline what’s missing.
The SF Systems Meetup is back! On 2/27, we're excited to have headline talks from the creator of FizzBee and a research collaborator with Signal. This is going to be a super fun night diving deep into making distributed protocols work, hope you'll join us! lu.ma/vqjf30k3
Excited to share our ICDT 2025 paper on a theoretical framework to connect CRDTs and the CALM Theorem! We formalize the intuitions given in the Keep CALM and CRDT On work about the gap between CRDT guarantees and monotonic queries.
fun to see hydro.run hit the top of Hackernews today. Happy to answer folks questions about Hydro in the thread there!
New year new startup 🤑🎆👌 Startup idea 10: Old dog cafe. Like a cat cafe but old dogs from the shelter that you can adopt.
Thrilled to share that our paper “Flo: A Semantic Foundation for Progressive Stream Processing” (with @mbpmilano, @alvinkcheung, and @joe_hellerstein) will appear at POPL 2025! Check out the preprint at arxiv.org/abs/2411.08274, and read on for more!
In case you missed my "award winning" Gong Show Talk at HPTS, connecting ***Yu-Gi-Oh!*** and distributed systems, you can now watch the prerecorded talk here: youtu.be/CK_pK3Mh3fU
The SF Distributed Systems Meetup (now under the SF Systems Club umbrella) is back! Join us 8/29 at @Databricks SF for an exciting evening featuring talks by Ben Hindman (co-creator of Mesos) and community members! lu.ma/x17bg5fh
Startup idea 9: Apple AirPods PhD. We've all been to boring conference talks with dull speakers. This September, put on the Apple AirPods PhD and enjoy the AI-enhanced speaker's voice, with some extra wit, humor, and a little soul.
