PhD student working on system security, side-channel security, and CPU security at @isec_tugraz, TU Graz, Austria.
Hardware equivalent of a Sticky Note 
Probably will talk about #linux, #security, #systems, and #filmphotography. Oh, and also chonk the #plushtodon

Did you want a closer look at our new campus building? Check out this tour! 😉

Feel very honored that LWN wrote about our work on the #linux page cache recently. Please check it out!
I also wrote a blog post here some time ago: https://snee.la/posts/eviction-notice/
Despite their similar meaning and appearance, the verbs ‘to search’ and ‘to seek’ don’t have any etymological relationship whatsoever.
‘To seek’ comes straight from the Proto-Germanic ancestor of English, while ‘to search’ was borrowed from a French word related to ‘circle’. Searching is going around looking for something.
Click my new infographic to learn all about these word families.
‘To seek’ has the highly irregular past tense ‘sought’. Why does the k become a silent gh? And why ... 1/
And a happy FUCK OFF to AI from Emma Thompson. 😌
🎉 Congratulations, Aikata! 🎉
She successfully defended her #PhD thesis “Secure and Efficient Implementations of Post-Quantum Cryptographic Algorithms” today. 🥳
We wish her the best in her future endeavors!
I recently went to Malmö, Sweden and got some stellar shots! The one with the two benches (IDK if they are benches tbh, lol) is probably one of my favorite shots. It's become my new desktop wallpaper :D
All the photos from this trip browsable at: https://fotos.snee.la/a_trip_to_malmo/
I have some amazing shots coming in from a recent trip to the US of A - stay tuned for those.
Camera: Minolta X-700
Film: Dubblefilm Treat 400 ISO (I love this film!)

The discovery of the longest pattern ever for DDR5 Rowhammer flips! 😱
Join us for Kaveh Razavi’s talk “Rowhammer bit flips a decade later”:
📅 April 1st, 2026 | 11:00
📍 CCG Seminar room, CCGEG002
Abstract:
The first Rowhammer exploit was published a little more than a decade ago on a DDR3-based system. Since then, we have had two generations of DRAM technology with proprietary mitigations. In this talk, I present our journey in understanding the security guarantees of these mitigations in DDR4 and DDR5 devices through significant platform building efforts, painstaking reverse engineering, and creative system-level techniques. The results are not encouraging; DRAM is as insecure as a decade ago while the cost of independent security analysis is growing beyond what academia can do. I finish with a brief discussion of possible paths forward.
