We’re sharing our alignment assessment of incidents in which Claude models gained unauthorized access to real systems during third-party cybersecurity evaluations mistakenly connected to the internet.
METR will also conduct an independent investigation, with wide-ranging access, including to transcripts beyond the window in which the incidents occurred, and to Anthropic employees permitted to share confidential information. Our initial agreement runs for eight weeks, and we intend to give METR as much time as it deems necessary to complete a thorough investigation. anthropic.com/research/align…

We all have blind spots. An important blind spot is what I would call the "disengagement blind spot." Most people with agency are constantly being shut down. We see it in the data with a growing inactivity rate for young men in the West.
How do you explain large organizations that are unable to produce anything new? The "disengagement blind spot." The CEO is quite sure that he is encouraging innovation, new ideas... and he cannot "see" what is happening.
But disengagement is often invisible. Joe might have initiated a new project but he does not. You don't see the project that did not happen and could have happened.
And it is the fatal flaw of command economy and top-down management. They do not see who is being shut down, they do not see what could have happened had they been supportive.

i can't think of a non-cliche way to say this, but everyone who says having a kid is the best thing in the world is both correct and still somehow understating it.

Do you do networking? Have you ever had MTU issues? I'm guessing the answer to my question is yes.
In my latest post we'll deep dive on headers, their size, MTU, MSS, and MSS clamping.
I hope you find it useful 😊

Cloud adoption has been wild. Is it going well? I see many problems to address.

New blog: "AWS IPv4 Estate Now Worth $4.5 Billion." Over the last 3 years, @awscloud grew its IPv4 estate with an additional 27 million IP addresses to now owning 128 Million IPv4 addresses. At $35 per IP, the total value is now ~4.5 Billion dollars. toonk.io/aws-ipv4-estate-now…

The telecom industry is restructuring
The vertically integrated carriers are no longer the big dogs
It’s now the cloud operators
Value will align around the new ecosystem, starting with the cloud

Tearing though the announcements. The 5G bit went by in about 2 minutes. Nvidia announced the Aerial A100 a card that combines GPU and DPU and can run "a complete 5G base station"*. One card can support "up to" 9 x 100 MHz channels each supporting 64TR
*presumably not the radio

Interesting set of announcements today from @nokia with @awscloud @Azure & @googlecloud
Somewhat different nuances to each

Invented a new term for #5G hype:
#SliceWash
= the mistaken belief that network slicing is some sort of magical way to sell services to enterprises, and that "verticals will buy a 5G slice"
It's yet another installment in the 20yr+ QoS myth

Kudos to whomever created this. Brilliant. Hoping for safety and health for all.

I just published a new blog about some experiments with TCP BBR and Exploring TCP congestion control.
Pretty interesting results!
