My favorite thing here is when you search for some scientific concept, and every other hit is Grok enabling some sort of cosmic crackpottery
From @schneierblog : "Prompt injection isn’t just a minor security problem we need to deal with. It’s a fundamental property of current LLM technology." The pragmatic path (for now) is to build safe *systems* and not waiting/hoping for safe *LLMs*. schneier.com/blog/archives/…

Hi, posting this a little late, but I'm very honored to have designed the cover of the @phrack HOPE release with p0rtL!

It was great to take part in the second edition of the Seeking Quantum Advantage conference in Oxford last week! There were talks spanning the latest developments in applications, quantum error correction, hardware and co-designing between different elements of the stack on the…
From @EtheHerring Emily Herring’s book Herald of a Restless World, it seems to me that Henri Bergson’s words offer the strongest argument for why we still need the humanities in an increasingly technological world.
And now, Jakob Steininger and Sergey Yurkevich have constructed a convex polyhedron that they have proved *not* to have the Rupert property. arxiv.org/abs/2508.18475

I'm once again looking at the epic 20-part essay which Ian Lance Taylor wrote about linkers lwn.net/Articles/27678… - did anyone ever write anything remotely comparable about the MSVC linker? Like, very remotely even?
Transforming human knowledge, sensors and actuators from human-first and human-legible to LLM-first and LLM-legible is a beautiful space with so much potential and so much can be done... One example I'm obsessed with recently - for every textbook pdf/epub, there is a perfect…
Pleased to contribute to a @Nature Opinions article on quantum myths! I wrote about claims that physicists have sent particles back in time. The other contributions include comments about entanglement, quantum computing, general relativity and more.
@ColtonSkees @spendergrsec @dodo_sec Yea this VMDragonSlayer is completely broken and never worked. The taint tracking is hardcoding TAINT_NONE and wacky hardcoded size limits even if it did work. No shadow memory, logging would be totally unoptimized.. hell the recursive path creation function isn’t even correct.
A popular NPM package got compromised, attackers updated it to run a post-install script that steals secrets But the script is a *prompt* run by the user's installation of Claude Code. This avoids it being detected by tools that analyze code for malware You just got vibepwned
NVIDIA research just made LLMs 53x faster. 🤯 Imagine slashing your AI inference budget by 98%. This breakthrough doesn't require training a new model from scratch; it upgrades your existing ones for hyper-speed while matching or beating SOTA accuracy. Here's how it works:…
