More On FFT

A nice ode to a bit of progress that has led to much of modern technology!

60 years ago this month, the Fast Fourier Transform (FFT) was introduced by Cooley & Tukey (1965) - one of the most important algorithms in signal processing and data analysis.

Do AIs Have "Rights"?

Human Vs. AI Reading Medical Notes

This question was posed recently on social media -- basically, asking someone to interpret a near-indecipherable orthopedic clinic note.  

My own translation:

Ortho
===========
R(ight) knee pain
R(ight) knee: + effusion, +pain, decreased ROM (range of motion)
Xray right knee: moderate OA (osteoarthritis)
A/P (assessment/plan): Right knee osteoarthritis
Right knee injection
F/u (followup) 3 months.

I also asked Grok AI to attempt to translate the image, and I have to confess it did surprisingly well!

 

 

 

Wave Confinement

"Thought To Be Impossible: Scientists Break Century-Old Physics Barrier". (Via H.R.)

A research team from POSTECH (Pohang University of Science and Technology) and Jeonbuk National University has achieved a groundbreaking feat: the complete confinement of mechanical waves within a single resonator—something long considered theoretically impossible. Their study, published on April 3 in Physical Review Letters, represents a significant advance in solving the century-old puzzle of bound states in the continuum (BIC).

Volokh On Pardons And Autopens

"Pardons and Autopen Signatures: A 2024 Appellate Decision Says Pardons Don't Have to Be Signed (or Even Written) at All".  

Professor Volokh notes:

Of course, something is required, and that something is presumably a statement by the President that he is pardoning someone. If (and this is a very big if) a President actually didn't make such a statement, and an assistant just affixed the President's signature to a document purporting to be a pardon without the President's authorization, then I don't see how that would be a valid pardon (at least unless it's somehow ratified by the relevant President). But that turns on a factual question about whether the President was actually involved in the creation of the pardons, not on a legal question about whether an autopen signature renders the pardon invalid.

Klein On Imminent AGI

Ezra Klein in New York Times: "The Government Knows A.G.I. Is Coming"

For the last couple of months, I have had this strange experience: Person after person -- from artificial intelligence labs, from government -- has been coming to me saying: It's really about to happen. We're about to get to artificial general intelligence. 

What they mean is that they have believed, for a long time, that we are on a path to creating transformational artificial intelligence capable of doing basically anything a human being could do behind a computer -- but better. They thought it would take somewhere from five to 15 years to develop. But now they believe it's coming in two to three years, during Donald Trump’s second term. 

They believe it because of the products they're releasing right now and what they're seeing inside the places they work. And I think they're right...

Young People Taking Classes To Learn How To Make Phone Calls

"Gen Z battling with phone anxiety are taking telephobia courses to learn the lost art of a call"

"They’ve [Gen Z] just simply not had the opportunity for making and receiving telephone calls. It is not the main function of their phones these days, they can do anything on the phone, but we automatically default to texting, voice notes, and anything except actually using a telephone for its original intended purpose, and so people have lost that skill," she explained...

The session involves practicing a series of scenarios where you have to make a phone call, for example, calling the doctors to make an appointment, calling in sick to work, and other everyday scenarios. The pupils are expected to sit back to back to mimic a regular phone call where they can’t see the person on the other end and practice by using scripts. 

Baxter said attending just one session boosts pupils’ confidence because it demystifies how phone calls really work.

UK Demands Apple Break Own Encryption

"UK orders Apple to let it spy on users' encrypted accounts"

Security officials in the United Kingdom have demanded that Apple create a back door allowing them to retrieve all the content any Apple user worldwide has uploaded to the cloud, people familiar with the matter told The Washington Post.

The British government’s undisclosed order, issued last month, requires blanket capability to view fully encrypted material, not merely assistance in cracking a specific account, and has no known precedent in major democracies. Its application would mark a significant defeat for tech companies in their decades-long battle to avoid being wielded as government tools against their users, the people said, speaking under the condition of anonymity to discuss legally and politically sensitive issues...

The law, known by critics as the Snoopers’ Charter, makes it a criminal offense to reveal that the government has even made such a demand. An Apple spokesman declined to comment.

The successful testing of HELIOS underscores the U.S. Navy’s commitment to integrating laser weapons into its fleet to counter evolving threats. Unlike conventional missile-based defense systems, directed energy weapons like HELIOS offer a virtually unlimited magazine, rapid engagement capabilities, and lower per-engagement costs.

In-Flight Screen Restriction

"Why United Does Not Allow You To Use In-Flight Screen As Extended Display"

Quoting The Points Guy:

As more travelers bring their own tablets and laptops on board, I've always wondered why airlines don't offer a screencasting feature on the entertainment screens. After all, it's a lot easier to get work done with some additional screen real estate.

Turns out, United can already technically enable screencasting today, Green said, but a major issue will likely mean that flyers will never see this functionality.

"We've had a lot of pushback from our corporate partners that say they don't necessarily want their staff using publicly available screens," Green said.

It's not that United would have access to any data; it's that they don't want nosy passengerssnooping in on their neighbors.

Gift Card Fraud

"Chinese Organized Crime's Latest U.S. Target: Gift Cards" 

Card draining is when criminals remove gift cards from a store display, open them in a separate location, and either record the card numbers and PINs or replace them with a new barcode. The crooks then repair the packaging, return to a store and place the cards back on a rack. When a customer unwittingly selects and loads money onto a tampered card, the criminal is able to access the card online and steal the balance.

We believe that, in 2025, we may see the first AI agents "join the workforce" and materially change the output of companies. We continue to believe that iteratively putting great tools in the hands of people leads to great, broadly-distributed outcomes.

We are beginning to turn our aim beyond that, to superintelligence in the true sense of the word. We love our current products, but we are here for the glorious future. With superintelligence, we can do anything else. Superintelligent tools could massively accelerate scientific discovery and innovation well beyond what we are capable of doing on our own, and in turn massively increase abundance and prosperity...
