People use LLM agents to interact with (access/modify) their system and external services. We (@bimalrajgyawali, @samkumar_cs, and Sai) think this can be a bit dangerous 💣⏲️💥 so we wrote a paper (arxiv.org/pdf/2506.13028) on system guardrails for such agent-driven interactions!

Excited to share that our paper, “High-Level Programming for Application Networks,” has been accepted to #NSDI '25! This marks the first step in realizing our vision for Application Defined Networks (ADN). More details in the thread!

I'm on a plane, and my flight is delayed for over 2 hours. Why? First, they had to replace a seat belt. But their computer didn't recognize the new part number, so they have to replace the entire seat before the plane is allowed to move. The computer made things less efficient...

This was a fun project! Developing the reading list as senior grad students, we got to re-read classic systems papers with a fresh perspective. And I'm glad that junior grad students at @Berkeley_EECS now have a more up-to-date reading list introducing them to systems research.

#ICYMI: “How can we design systems to use cryptography efficiently and manage overheads?” @samkumar_cs Kumar unpacked how to rethink cryptography in the overall system in our interactive #TechTalk. Thank you, Sam, for this thought-provoking session & @gnychis for moderating it.
