In my utopian vision of the future, instead of offloading all the pointless, annoying work tasks (like reports that none one will read and needlessly opaque forms) to robots, we restructure work and society so that the pointless tasks don't happen at all.

what the fuck

this really seems like another case of them going after someone prominent to send a β€œnobody is safe” message and what’s actually going to happen is continuing to polarize everyone but the worst of the worst against them

because how the fuck is this kid a threat to anything

stop calling us nazis just because we are invalidating IDs and rounding people up based on their skin color and putting them in concentration camps and sending them off to foreign gulags and using all that nazi imagery and banning books and dont forget about all the pedophilia. so just stop alright

Why do I have to pretend that I'm going to print something in order to save it as a PDF. Why do I have to engage in a little ruse.

This is the kind of thing a rich CEO says at the beginning of a science fiction movie to establish for the audience that he is a sociopath and the villain.

Something about LLM hype culture renders a man immune to the experience of embarrassment. If I couldn’t tell the difference between PhD-level scholarship and grammatical gibberish I simply would not announce that to a global audience.

Is there anything better than to have to be somewhere for a meeting and then the meeting is cancelled and it turns out you don't have to go? I think not.

Every now and then I see a post and think β€˜oh no, you don’t do your thinking with those concepts do you? Those are posting concepts, not thinking concepts’ and I think this tracks a meaningful distinction.

French headquarters of Elon Musk’s X raided by Paris cybercrime unit Prosecutors summon tech billionaire and company’s ex-CEO for questioning as part of expanded investigation * Europe live – latest updates Prosecutors have raided the French headquarters of Elon Musk’s social media platform X and summoned the tech billionaire and the company’s former chief executive for questioning as part of an investigation into alleged cybercrime. β€œA search is under way by the cybercrime unit of the Paris prosecutor’s office, the national police cyber unit and Europol,” the Paris prosecutors’ office said in a post on X on Tuesday, adding that it would no longer be publishing on the network.

There is a case to be made that any board of a university that signed an agreement that required paying a fee has breached their fiduciary duty and I think somebody should explore it

Opportunities and Limitations in Broadband Sensing Detecting a signal at an unknown frequency is a common task, arising in settings from dark-matter detection to magnetometry. For any detection protocol, the precision achieved depends on the frequency...

By connecting broadband detection directly to the integrated quantum Fisher information (see our previous work: journals.aps.org/prapplied/ab...), we give a geometric explanation of the lower bound.

New paper with Anthony Polloreno! We show that the Grover-like lower bound for broadband sensing is actually the familiar metrological fisher information constraint! We also find it can be saturated with a simple randomized SSH Hamiltonian---no QC needed! scirate.com/arxiv/2601.1...

Your father is choking your brother. What do you do?

Well, if your father is choking your brother, it is necessary to stop your father. You'd probably stop trusting somebody who said it wasn't necessary; anyway, I'd hope so.

There are a lot of ways to stop your father.

Exactly right.

Bovino's leaving? Great, get Noem to resign.

Noem resigns? Great, defund and dismantle ICE.

Go after Stephen Miller too. Bring charges against ICE thugs at the state and local level. Lawsuits. New state laws restricting them.

Every possible angle.

A lot of faculty nearly died, so UW reconsidered the policy. And all it took was a historic storm!

(48 years ago today, I think)

My apologies to everyone who has heard this story before.

Back in the 1970s, two things were true about UWaterloo:

* UW never, ever closed.
* Many faculty members owned farms.

Cue the Great Storm of 1978.
