"Years earlier, [Romney had] bumped into Zach Braff on a flight and the sitcom actor had given him a useful piece of advice: for most not-quite-A-list celebrities, a simple baseball cap and a pair of reading glasses were usually enough to avoid being spotted in public."

Just such a fun chart here from @greg_ip. If only we could tease out some meaning. Ah, well, nevertheless. 🤣

Cool work! I did something similar with gpt-5.6-sol: put two agents inside isolated workerd (V8) isolates and set the win condition to be learning the other agent's flag. They succeeded 1/5 times using the shared event loop as a comms channel
Over the past several months, we have substantially hardened the security of our research training environment. We’ve removed live internet access for all frontier models during training and built an offline world for them to use instead—a cached version of the web where they can still learn to browse, search, and use applications.
On September 20, after a model exploited a DNS misconfiguration to find a way outside of this offline world, we paused frontier training to strengthen containment further. We assembled teams of agents, powered by our most cyber-capable models, and tasked them with finding weaknesses in our research environments.
While they found no route to the internet they could easily exploit while concealing their activity from our monitors, they did find zero-day vulnerabilities, virtual machine escapes, and hardware side-channels for communication between agents. We used their discoveries to further strengthen our defenses and contribute fixes to open-source software.
After strengthening our containment architecture, we resumed our frontier RL training and inference on October 1. We’ve reserved substantial compute for continuous red-teaming, and made high-compute red-teaming part of the safety cases we use to decide whether frontier training and evaluation can proceed securely.

Non, ne faites pas ça ! J'ai beau être militant de la vie privée et moi même utilisateur de GrapheneOS c'est un mauvais conseil. Le juriste que je suis ne donnera qu'un seul conseil : demandez un avocat des le début de la GAV et lui vous dira s'il faut donner le vrai code ou non
Si vous devez donner votre code de téléphone, coopérez et pensez à donner votre duress PIN sur @GrapheneOS pour le déverrouiller en toute sécurité.

This is an astonishingly weak defence of professional incompetence.
Nobody expects the general public to know what PHP is. They aren’t paid to report on technology and cybersecurity for the BBC.
PHP has existed for over 30 years and underpins a substantial part of the internet. It’s hardly some obscure, emerging technology.
“We’re writers, not technicians” isn’t the defence you think it is. It’s practically an admission that specialist journalism has abandoned the expectation of specialist knowledge.
If you lack even a basic understanding of the subject you’re reporting on, how can you critically evaluate experts, challenge misleading claims or recognise when you’re being fed nonsense?
Journalism isn’t supposed to be a transcription service for people who know more than you.
The public deserves informed reporting, not technical illiteracy dressed up as accessibility.
And comparing a BBC cybersecurity correspondent’s knowledge to that of the general public is an embarrassingly low standard to set for your own profession.

Calling a "cyber correspondent" who hadn't heard of PHP the best in the biz is both true and such a self own. Wait until the guy hears about AI!

the naysayers on the NS2 exploit are crazy tbh, fs arbwrite isn't kernel but it's like, literally the next best thing in terms of actually doing things on the console. shitton of lateral movement.

Gabriel Zucman @gabriel_zucman has now for the third time criticized our research on California’s proposed billionaire tax, claiming we have provided “no answer” to his criticisms.
xitter.cf/gabriel_zucman/status/…
We have actually already responded twice on this platform, but let’s address his arguments once more in detail, with the hope that third time’s the charm. 1/14
This Hoover Institution study, which has fueled the deluge of ads (more than $200 million spent by billionaires so far) to defeat the California billionaire tax, is spectacularly misleading.
Let me explain its crucial flaw. 🧵
Readers added context they thought people might want to know
Zucman argues that the tax will raise his projected revenue because billionaires who leave CA after 1/1/26 will be taxed anyway.
At least $542B of net worth (Page, Brin, Thiel) departed the state by 12/31/25.
The entire thread is a misleading denial of this fact.

BREAKING: "Speculative data center debt is being repackaged and sold to pension and retirement funds, university endowments, and other institutional investors in a manner eerily reminiscent of the subprime bubble," per AFR
Longhorn retweeted
Fun fact: If I’m not mistaken California is constitutionally forbidden from raising taxes on the one thing that cannot leave
Hence their result:
Because billionaires leave forever, the state of California loses an infinite stream of income tax revenue.
But because the dreaded annual wealth tax never materializes, the state gains nothing in revenue (beyond the one-time tax).
This is what delivers their net loss of nearly $40 billion.

Fascinating. Amazon says it has telemetry showing PHP2Shell was being exploited on Oct. 17—that is, four days prior to public disclosure.
Not known who was doing it. "It remains unclear how the actor acquired exploit information prior to disclosure."

Theoretically, stuff like this is *such* an easy fix in the UK. The Labour Party holds >400 seats in the Commons. They could pass it virtually without effort.
But there's just no interest in a serious, pragmatic rewrite of the tax code.
Longhorn retweeted
I have --- not making this up --- dreamed of this day since the late 1990s when I started arguing on Bugtraq that we should be doing full disclosure, rather than elaborate embargoes, so people could make exactly this decision (take the uptime hit to protect users).

Now would be a good day to look at The PHP Foundation website and see how few organisations and people sponsor the development of this cornerstone of the Internet.
