The software to create the black hole in the movie 'Interstellar' is a full implementation of Einstein's equations in 40,000 lines of C++, and rendered thousands of 23-megapixel IMAX frames on a 32,000-core render farm at about 20 core-hours per frame: arxiv.org/pdf/1502.03808…

We have 3 space dimensions but only one dimension of time. Why is there just one time? What would happen if there were more time dimensions? A short 🧵that requires some math. (You can probably follow w/o math as well) 1/16

Thread: Unpopular opinion: The Pwnie Awards are becoming an anachronism and it’s time for change. This is not a critique of those who worked hard to make the PWNIEs what they are today. It's about a way forward.

Once again, well done Hany Ragab and Enrico Barberis! With your outstanding efforts, we went from "Maybe we should write up a short paper on this analysis" all the way to award overflow state! Very well done!

Bittersweet farewell to VUSec! I’m so grateful for this incredible journey & the invaluable experience gained. Huge thanks to all my profs., specially Herbert Bos & Cristiano Giuffrida, I learned a lot from you guys. Thanks to my colleagues & friends who made this chapter unforgettable

Check out my latest work #GhostRace, where we microarchitecturally bypass all sync primitives by speculatively executing critical regions that are concurrently being architecturally executed by other threads, turning all race-free critical regions into Speculative Race Conditions

For the first time, we imaged and reverse engineered 6 modern DDR4/5 DRAM chips (comsec.ethz.ch/hifi-dram) Due to the incredibly small feature size of modern ICs, we use SEM combined with FIB reaching pixel resolutions as low as 3.4nm. Then we evaluate 10 years of DRAM research.
