"Anthropomorphizing" the HuggingFace incident is a problem. In most respects, the AI no more went rogue than your car went rogue when you failed set the brake and it started rolling down the hill. The metaphysics here is that the AGENCY and the REASONING are two different parts.

Dear #Apple, Who on Earth came up with the idea of running LLM quantisation of all my data after upgrading to #macOS 27 making it impossible to run anything which needs I/O like Parallels? The machine is floored and, after 24hrs, it is still at 7.1% of the job. Can the adults come back, please?

If you use WireGuard on FreeBSD you urgently need to patch¹. And I mean urgently. __ ¹ security.freebsd.org/advisories/F...
II.  Problem Description

After dispatching a decrypt operation to OCF and receiving the result, the wg(4) driver failed to check whether the MAC verification step succeeded.
The driver thus silently accepted packets with an invalid Poly1305
authentication tag.

III. Impact

A remote attacker who can send UDP packets to a WireGuard endpoint, and who can guess the bounds of the receiver's replay window, can inject forged or modified transport data packets into the tunnel.

A remote attacker who can intercept WireGuard packets bound for a FreeBSD host can modify the ciphertext and authenticated data without detection by the receiver.

The lyrics of "Spirits in a Material World"¹ by The Police resonate more and more… To think it was the height of the Cold War and we thought it was bad. We had seen nothing :( __ ¹ genius.com/The-police-s...
[Verse 1]
There is no political solution
To our troubled evolution
Have no faith in constitution
There is no bloody revolution

[Chorus]
We are spirits in the material world
Are spirits in the material world
We are spirits in the material world
Are spirits in the material world

[Verse 2]
Our so-called leaders speak
With words, they try to jail you
They subjugate the meek
But it's the rhetoric of failure

[Chorus]
We are spirits in the material world
Are spirits in the material world
We are spirits in the material world
Are spirits in the material world

[Verse 3]
Where does the answer lie?
Living from day to day
If it's something we can't buy
There must be another way
[Outro]
We are spirits in the material world
Are spirits in the material world
Are spirits in the material world
Are spirits in the material world
Are spirits in the material world
Are spirits in the material world
Are spirits in the material world
Are spirits in the material world...

People have been complaining that "In my day, we had to OPTIMIZE our code" since the dawn of computing. Here's a pull quote from 1977. (Source.)
A callout text in the middle of an article that reads:  "When you had only a little memory, you wrote clever little programs, and prided yourself on doing something efficiently and elegantly."  From ROM: Computer Applications for Living Magazine, Volume 1, Number 2, page 24, the article "Memory, Memory, How Much Memory?" by Stan Veit.
