Really fun experience! Thanks @cachemisses.bsky.social for being such a great host. Let's bring more systems research to software developers!

Excited to announce that the Fray paper has been accepted to OOPSLA'25! Work led by @aoli.al with a full pastalab.org collaboration. 📄: rohan.padhye.org/files/fray-o... 💻: github.com/cmu-pasta/fray 🎥: www.youtube.com/watch?v=AX6P...

These talks look great. Next Tuesday May 12th in the DMV. lu.ma/swn68ky0

I've now written enough Rust to know that (a) Rust is a great language, (b) Async in rust is a flaming dumpster and (c) that fire has spread so far that it makes the whole language incredibly frustrating to use on a day-to-day basis...

New blog post: "Build your own S3-Select in 400 lines of Rust" Check it out 😉: blog.xiangpeng.systems/posts/build-...

We are excited to share Fray Debugger (aoli.al/blogs/deadlo...), an IntelliJ plugin that allows you to control concurrent execution deterministically! We have translated the Deadlock Empire (deadlockempire.github.io) into Java to demonstrate how to use Fray Debugger.

Wrote a blog post reflecting my thoughts on DeepSeek, NSF funding and system research communities in general. Apologies for the bold claims -- hope they can invite some discussions. blog.xiangpeng.systems/posts/system...

@xiangpeng.systems shared a great post about system researchers. I wrote a comment on it and would like to share some thoughts here and offer complementary ideas. In short: build paper with open source. xuanwo.io/links/2025/0...

It's wonderful to see practical & important programming work. Debugging concurrent programs is incredibly difficult, here is a bug found in Apache Lucene by the CMU Pasta Lab using their new Fray testing framework www.elastic.co/search-labs/...
