Finally got around to reading this! Super enjoyable, and the concepts remind me a lot of @shadaj.me’s work on hydro.run and distributed stream types. Good abstractions for reasoning about distributed systems as a single program seem…pretty awesome?

Distributed Systems Programming Has Stalled Over the last decade, we’ve seen great advancements in distributed systems, but the way we program them has seen few fundamental improvements. While we can sometimes abstract away distribution (Spark,...

New Blog Post! www.shadaj.me/writing/dist... 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. arxiv.org/pdf/2502.00222

SF Systems Meetup 2024 - Transactions and Serverless are Made for Each Other | DBOS

Better late than never 😂 Happy to share a recap of my SF Systems talk from last month. I've put together a summary of the session along with some great Q&A moments: www.dbos.dev/blog/sf-syst...

Thanks to the organizers and everyone who showed up—it was an amazing experience!

Quickstart | Hydro - Build for Every Scale In this tutorial, we'll walk through the basics of Hydroflow+ by building a simple dataflow that prints out the first 10 natural numbers. We'll start with a single process, then pipeline the computati...

Flo itself is a theory paper, but we are actively using it as the foundation for our high-level Hydro APIs (where we use Rust types to enforce Flo properties): hydro.run/docs/hydrofl...

The goal of Flo is to be a unifying semantics, and to that end we show how the core ideas of existing systems like Flink, LVars, and DBSP work perfectly in the Flo model!

With Flo, we aim to extract the *essence* of streaming systems into formal properties: streaming progress, which formalizes keeping outputs up-to-date, and eager execution, which guarantees determinism in the face of arbitrary scheduling.

Streaming systems have broad “vibes” about responding to events in a timely manner and tolerating scheduling delays gracefully. But these “vibes” have remained informal and each system has brought its own (incompatible) set of guarantees.

Flo: a Semantic Foundation for Progressive Stream Processing Streaming systems are present throughout modern applications, processing continuous data in real-time. Existing streaming languages have a variety of semantic models and guarantees that are often inco...

Thrilled to share that our paper “Flo: A Semantic Foundation for Progressive Stream Processing” (with @mpmilano.bsky.social, Alvin Cheung, and @joehellerstein.bsky.social) will appear at POPL 2025! Check out the preprint at arxiv.org/abs/2411.08274, and read on for more!

Hey, author here, glad you found it interesting!

My talk yesterday at #SFSystemsMeetup was based on this paper. I'll share the slides soon. Thanks a lot @conorpower23.bsky.social @shadaj.me @cwensel.bsky.social and Neil for inviting me! Also thanks Jeff @ Chroma for hosting the event 💙

SF Systems Meetup: Data Center Networks and Serverless Transactions · Luma The SF Systems Meetup is back! This month, we're excited to have a double header, featuring talks from Alex Krentsel (Google Systems Research) on the latest in…

I'm presenting at the upcoming SF Systems Meetup! I'll dive into a new serverless architecture for stateful applications, managing function/workflow execution state using transactions. It's the research behind @dbos.dev

Everybody need @shadaj.bsky.social! I saw him first programming Scala at a meetup with his dad when he was 7. Since then the whole family presented at scale.bythebay.io and he does some of the coolest stuff in software. Follow the future!:)
