🚀 PhD position open in my SPEAR lab @tudelfteemcs.bsky.social

We build systems that become startups and shape Internet standards. Our research becomes startups, influences RFC discussions, and powers real edge deployments.

Join us to create the self-organizing Internet of tomorrow 👇

This work has also won the Best Poster Award at

Goldydocs A two-dimensional filesystem build and distribution framework for containers. Learn More GitHub

🎓 Giovanni Bartolomeo will present 2DFS on Wednesday at 2 pm in Boston. Come see containers that adapt to your #DistributedML pipeline!
Code & artifacts already on GitHub and fully-reproducible.
See 2dfs.github.io
Paper: www.usenix.org/conference/a...

2DFS 👉 alternates along two axes:
1. Independent allotments of model weights & deps → tiny, surgical updates
2. On-demand partitioner & cache hierarchy → automatic splits for split-compute

Result? 56 × faster builds and 25 × better caching efficiency with negligible overhead!

[🚀 In ATC ’25 on Wed 14:00]
How can we bring near-zero-overhead elasticity to ML workloads? Check out “On-Demand Container Partitioning for Distributed ML”. Our answer is 2DFS that lets images be sliced (& updated) on-the-fly while staying 100% OCI compatible. [1/3]

Really sad to see ATC die. I related more to it than OSDI/SOSP as the venue encouraged "hacky" research outside of mainstream systems topics.
I am glad we will be presenting at this ATC"On-Demand Container Partitioning for Distributed ML"
This will be our swan song.

Less than a month to the HotOS 2025 deadline (January 15). Submit your “hottest” systems ideas (by which I of course mean most interesting and fun ideas), and come hangout in Banff for two days in May. More details in the CFP at sigops.org/s/conference....

Thank you so much for the goodies @ellapeltonen.bsky.social! It was super fun helping with the organization of #IoT2024 and I am bummed that I couldn’t travel to Oulu for the fun.
Thanks for the small taste of Finland and kudos to my fellow #TPCChairs Jan and Isabel for an amazing experience!

Finally had some time to dig into the subsea cable cuts in the Baltic Sea that have gotten a lot of attention lately.

Due to the rich fabric of connectivity in the region, the loss of the two cables caused minimal disruption.

However, here are some subtle BGP impacts I was able to identify. 🧵

Had an amazing time at ACM #HotNets this week! Inspiring talks, bold and creative ideas, and such a welcoming community. The UCI campus and Irvine made for a stunning backdrop. Huge thanks to Sangeetha and Athina for organizing so well!
