can’t tell whether this bullshit take that LLMs are the same as fuzzers conceptually (just another tool, nbd) is cope or actual ignorance

This is from Anthropic's Mythos preview post @ red.anthropic.com/2026/mytho…

πŸ€” I'd need to examine the bug, its setting, how much input/app state can be manipulated before I could say for sure.. but 3 bytes OOB is often 2 more than needed to get new primitives/code exec. I wonder if the team assessing this had any past experience manually shaping heaps?

... in IIS I think? Another hacker (whom I respect highly, left unnamed) bet me that the bug wouldn't see a real exploit written. It was unfair as I knew how close the exploit was. TL;DR it landed, and I worry the wisdom from that era is lost among the teams that need it most now

Alas it was a different time: the payout itself was another zeroday. And the hacker against whom I bet indeed made good on their end of the wager, dropping a kernel bug in the IRC channel for all to see! I'll see myself to the retirement home now.

Start your day with a little container sidechannel 0day, as a treat
Found a side-channel that lets containers communicate across isolation boundaries. No shared volumes, network, or privileges. Just POSIX advisory locks on /proc/self/ns/time. Built a working cross-container IRC chat to demonstrate. Works on default Docker/K8s. h4x0r.org/funreliable/

❌ No type safety ❌ No argument count ❌ Can’t wrap one vararg API in another ❌ Can’t push/pop args or introspect You're stuck in a model where the caller has to be perfect. That’s not an interface, it's an improv show with segfaults. h4x0r.org/vargs/

wow this is the dumbest shit I have ever read. Tape is an amazing long term storage solution for records you can’t afford to lose. Also $1M is a drop in the bucket for government spending.
The @USGSA IT team just saved $1M per year by converting 14,000 magnetic tapes (70 yr old technology for information storage) to permanent modern digital records.
Community note
Despite its age, magnetic tape is still highly favorable for long-term, static data archives. It offers cost-effectiveness (cheaper than disk/cloud), longevity (outlasts disk drives), offline security (resists cyber threats), and high capacity (up to 50TB per tape). research.ibm.com/blog/tape-dens… corodata.com/tape-backups-s…

Sigh...not that it matters or anything but we have a whole array of underwater microphones to spot subs. Remember the Titanic sub that imploded and the Navy was like "yea we have the audio"? I know this and I'm just a guy who annoys Navy officials and reads books...

Who know what's crazy? When you say you don't want titles or money but space to work on something important without disruption, people are looking at you like you are crazy. This is why America is losing.

If you thought that there were privacy risks from TikTok, imagine the privacy risks from using an *online* LLM service that is run in China... Already people are in the habit of using LLMs to summarize uploaded documents, etc. The time to focus on private AI inference is *now*.

What really frighten me is that people no longer know what "liberalism" is. Among the uneducated public, it's been warped to mean "left-wing". Among the educated, it means tolerance, individual rights, rule-of-law, democracy -- the blueprint for how western society's work. It's like sportsball: different teams fight to win the game (where political parties are the teams), but "liberalism" is the rules of the game. Internationally, Russian and China are the major threat to liberalism. Domestically, it's wokism and Trumpism. Woke Marxism dominates college campuses to a toxic extent. Trump appeals to the most ignorant and brutal of our society. Liberalism is what the never-woke and never-trump centrist people fight to defend. But we can't even have a simple conversation about it because for some reasons, civics classes in high school have stopped teaching "liberalism".
Just 25 years ago, liberalism was the world's dominant ideology. Now, in 2024, it's on the run everywhere, pushed underground by a combination of 21st century technology and the power of the Chinese Communist Party. noahpinion.blog/p/liberalism…
