I say this as a lover of FHE and the wonderful cryptography around it: While it’s true that FHE schemes continue to get faster, they don’t really have hope of being comparable to plaintext speeds as long as they rely on bootstrapping. For d

This isn’t some conspiracy, it’s just CYA. They know your general location from your IP and device APIs, they don’t encrypt business messaging, and they comply with subpoenas.

Excited to see someone finally doing this! I can imagine folks with sensitive model weights being especially interested. Do you run into rate limits or other issues with TLS cert issuance? One problem we had when doing this before is that e

Call it the iron law of LLMs: "No worthy use of an LLM involves other human beings reading its output." If you use a model to generate code, let it be code nobody has to read: one-off scripts, demos, etc. If you want an LLM to pro

I know this would be less fun, but given that the key space was only 36^4, why not just run the actual decryption functionality in QText? Like, even if it takes 1 second to decrypt, spin up 32 cores and wait a day. They allude to the idea t

Honestly, I think even the old Caltrain cars were pretty clean. The only dirty parts were the bathrooms (and honestly, train bathrooms are sort of gross most places). Caltrain has always been sort of luxury, though; the median Caltrain ride

I think BART struggles with who it's meant to serve now, since it was clearly designed for ultra-peak weekday commute traffic. Recovery for weekend ridership is way better than weekday. I also agree that the governance structure for BA

Totally agree, though SF is closer to overall NYC density than you'd expect (NYC 29k, SF 18k ppl/sq mi; Manhattan is 73k). I think the Bay Area suburbs are also egregious - e.g. North Berkeley BART station is surrounded by single

The electric Caltrain is so wonderful. It’s way quieter, the cars have nicer interiors, and it is running faster and more frequently than before. Between this, the new BART cars (also much quieter!), and Muni hitting a reliability & sat

These watermarks are not robust to paraphrasing attacks: AUC ROC falls from 0.95 to 0.55 (barely better than guessing) for a 100 token passage. The existing impossibility results imply that these attacks are essentially unavoidable ( https:

I feel like the killer feature is playing all the old games. Sitting on the couch and feeling like you know the answers is so different than having to actually buzz in and say them on the spot!

This is such a neat idea, and you get the gist of it from just the screenshot. I wonder what kinds of 'integration' you could do (clipboard, opening links, drag-and-drop, etc). I could see this as an educational tool for doing dev

This seems really useful for stuff like AMD SEV-SNP, where we want a measurement of the (kernel + initrd + arguments) to guarantee certain behavior from the machine. Ideally, we could use this as the container hypervisor, and have it produc

It's exciting that cryptographic constructions (like m/n secret sharing where m is hidden) can solve problems in complexity; I would have expected things to flow mostly the other way.

Concrete is really impressive and permissively licensed. The ML library has a FHE version of (a subset of) scikit-learn, which I honestly thought I’d see in another 5+ years. Like look at this example: # Now we train in the clear and

I'm not an expert, but I see the main threat to continued improvement as running out of high-quality data. LLM's are a cool thing you can produce only because there is a bunch of freely available high-quality text representing (es

The idea that nobody is entitled to privacy until they turn 18 is crazy. I shudder for all the LGBT kids whose parents all now have a (state enforced!) right to snoop on them. (Honestly headline should be: “Utah bill gives parents full acce

This is really cool. Federated learning seems like it could unlock a lot of value in healthcare settings. Have you had any luck convincing hospitals / insurers / etc that this satisfies HIPAA and is safe? How do you convince them?

What if instead of trying to evaluate these models privately, which tends to have a lot of overhead, we instead try to mix lots of user queries and send them in batches? We could use enclaves to do the mixing, and while there’s be added lat
