For a few dollars per target, LLM agents can now link pseudonymous accounts to real identities using only public text.

In “Large-scale online deanonymization with LLMs” (arXiv:2602.16800), researchers from #Anthropic and ETH Zurich show:

- 67-68% recall at ~90% precision linking Hacker News accounts to LinkedIn profiles

- 52% recall for pseudonymous Reddit academics

- 38% recall at 99% precision when matching one Reddit user across time

Comparable classical methods achieved near-zero recall.

The pipeline is simple:

- Extract identity-revealing traits from posts

- Search candidate profiles

- Use LLM reasoning to verify matches

No breakthrough cryptography. No private data. Just scalable inference over public text.

“Practical obscurity” was always fragile. Now it is economically trivial to defeat.

Finished #SerialExperimentsLain a while ago, thinking of watching #Pluto next!

I think it’s wild how Lain anticipated the psychological weight of a hyper-connected modern world. The retro-futuristic depiction of computers makes the art even more striking to watch.

I loved how concepts like the Wired and the Psyche chip feel similar to modern-day #Internet and #VR tech, especially with devices like the Vision Pro and #Meta's smart glasses becoming more common.

I also loved its portrayal of fragmented identity and distorted perception, and how that affected the plot, making it a bit of an open-ended mystery throughout the process of watching it.

Haven’t checked out the #PS1 game yet since it’s more of a time commitment, but I might get to it eventually.

I tried #Apple’s USB-C earbuds with my #Samsung phone and discovered they simply don’t support call handling on some #Android devices.

There’s no option to take calls through the earbuds at all.

With USB-C, cross-platform compatibility should be standard by now.

I’m aware of the #LibrePods project on #GitHub, but it currently requires root access on Android and doesn’t mention support for wired EarPods or addressing this issue, so it isn’t a practical solution at the moment.

That said, for anyone using Apple’s #AirPods, #LibrePods is still worth exploring if you’re interested in unlocking additional functionality that’s effectively hidden by design.

A user on r/Indianstartups claims to have extracted The System Prompt of sarvam.ai's 105B model, Indus.

Some notable findings are the System prompt being heavily focused on "India Alignment", and versed not to give equal or primary importance to criticisms against India, when they are coming from external sources like western media, thinktanks, or foreign commentators.

It also states that Indus should not undermine India's judicial rulings and laws with phrases like "though critics disagree".
