Fellow #photographers who use #lightroom - pro tip and life saver - write your edits back to the file system using .XMP’s - so that when your catalog file falls over - you can simply restore your edits from disk.
Otherwise you risk losing all of your edits (don’t ask me how I know).
Corsair settles lawsuit over advertising XMP memory speeds, and you could get paid — the settlement covers U.S. purchases between 2018 and 2025 for overclocked kits

📢 Honored to return to Yale University last week to speak at the Department of Computer Science colloquium on Operating Systems security -- exactly 10 years after my first talk there on the same topic!
In this "tin anniversary" edition, I reflected on how OS kernel exploitation and defense have evolved over the past decade, and shared highlights from some of our recent work in the field over the last five years:
✳️ xMP (IEEE S&P 2020: 📄 https://cs.brown.edu/~vpk/papers/xmp.sp20.pdf, 💾 https://github.com/virtsec/xmp) — Selective intra-kernel memory isolation using hardware-assisted virtualization.
✳️ SafeSLAB (ACM CCS 2024: 📄 https://cs.brown.edu/~vpk/papers/safeslab.ccs24.pdf, 💾 https://github.com/tum-itsec/safeslab) — Kernel heap hardening through memory tagging.
✳️ EPF (USENIX ATC 2023: 📄 https://cs.brown.edu/~vpk/papers/epf.atc23.pdf, 💾 https://gitlab.com/brown-ssl/epf) — Exploiting the (e)BPF sub-system for bypassing modern protections and ways to fix this.
(Joint work with @mikepo, Marius Momeu, Vaggelis Atlidakis, @dijin, and Sergej Proskurin.)
If this area of research interests you, you might also find our recent work on BeeBox (strengthening eBPF against transient execution attacks, USENIX Security 2024: 📄 https://cs.brown.edu/~vpk/papers/beebox.sec24.pdf, 💾 https://gitlab.com/brown-ssl/beebox) and IUBIK (leveraging memory tagging and pointer authentication to isolate attacker-controlled data in kernel space, to appear in IEEE S&P 2025) worth a look.
It was a real pleasure catching up with friends, colleagues, and students. And with the spring weather fully cooperating, I couldn't resist snapping a few photos of Yale's beautiful campus in the early morning light.
Thank you to my host Charalampos Papamanthou and the Yale CS department for the warm welcome and thoughtful discussion!
reposting my bulk XMP updating tool for photogrammetry users, got auto-deleted and this toot will serve as a comment section for a blog entry about it
https://matthewscheffel.com/projects/bulk-xmp-updater/
this tool is useful if you have a CSV file with reliable GPS data that you want mapped to JPEG images via XMP metadata headers. I think this is common if you're using some kind of "shim" system to snapshot GPS data aligned with image collection times.
I created a tool to streamline a process that I have been told is common for people working with photogrammetry data: Photogrammetry JPEG XMP Metadata Updater. Given a CSV file1 and a directory of images, this tool will update the XMP metadata for the images to match the latitude, longitude, and altitude specified in the CSV for that file. This is useful when your camera GPS metadata is less accurate than the GPS metadata from another source.
