queuebert··on Apple restricts Pebble from being awesome with iPhones
And yet haven't iMessage 0days been used to track and kill people? Even without opening the message?
queuebert··on Apple restricts Pebble from being awesome with iPhones
This is a false dichotomy. You can build a system that is secure by default but allows you to opt out with sufficient technical knowledge.
queuebert··on Jensen Huang – Nvidia GTC 2025 Keynote
While we're at it, what does Nvidia mean?
queuebert··on Zlib-rs is faster than C
Why do you say that? I would say SIMD is pretty well figured out in well-written code, e.g. small, tight loops over vectors. Unrolling and vectorizing a loop is not that hard and happens constantly on all our phones for signal processing, for example.
queuebert··on Stupid Smart Pointers in C
C is the LS engine of programming languages. People love to drop it in and mod it until it blows up.
queuebert··on “QWERTY wasn't designed to solve type bar jamming” [pdf]
Thanks for sharing your experience. Hearing that you went from being proficient at Dvorak to Workman and in the end prefer Workman motivates me to try it.

Dvorak is awful for the shell, but actually not bad for vi. Do you have any experience with Workman and vi?

queuebert··on “QWERTY wasn't designed to solve type bar jamming” [pdf]
Dvorak is way more comfortable and is very fast for me, but its emphasis on alternating hands causes me to frequently invert pairs of letters when typing fast, probably because my left and right brain isn't perfectly coordinated.

I have considered switching to Colemak, which is supposed to have less of that, but as a 100+ wpm typer of Dvorak it really is diminishing returns.

queuebert··on NASA to launch space observatory that will map 450M galaxies
This is nonsensical. Do you mean a tiny movement in the field of view, which should be measured in angular distance?

Or do you mean actual motion through the universe, in which case the galaxies are moving at hundreds of kms per second, which means they would move billions of kms in 6 mos.

queuebert··on Portable MRI Scans Patients for Signs of Stroke
CT is not much faster than a quick T1 and T2 from a portable MRI these days. By the time you transport to the CT suite, set them up, run the scout, etc., you could have acquired the MR bedside.

Edit: To add some clarity, portable MR systems are low field, so that means the scans will be lower SNR and resolution, which are much faster to acquire. I think it would also rule out diffusion scans, since those require high gradients. MR acquisitions are also much faster nowadays due to compressed sensing and deep learning reconstructions.

Maybe someday it can be part of a Galactic Positioning System.

queuebert··on Who's Afraid of Peter Thiel? A New Biography Suggests We All Should Be (2021)
He's smart enough to fool the masses that he's a genius scientist, but, as a scientist myself, he looks to me like a gifted manager and maybe a genius at hiring.
queuebert··on Who's Afraid of Peter Thiel? A New Biography Suggests We All Should Be (2021)
I think some people may be misreading what you wrote to mean China is freer than the US, but I think you are saying that China does not allow billionaires to threaten its government, which is probably accurate.
queuebert··on How the U.K. broke its own economy
As a former landlord, I would not compete with buyers on a potential rental property. I'd rather pick it up cheap because it is an investment. So the correlation between ownership and prices is not as clear to me, and landlords may provide some market making service. The connection between supply and prices is very clear, however.

Another issue is that historically low mortgage rates pushed up the maximum price of house that people could afford, and when rates went back up the market stalled out rather than price correct. I don't know how to fix that.

queuebert··on Tattoo ink exposure is associated with lymphoma and skin cancers
That's the entire point of twin studies and case controls. Did you read the article?
queuebert··on Dozens of U.S. academics lose grants from Minerva Research Initiative
I always thought the heat was the driver. There has historically been more crime in the summer than in the winter, for example. Heat makes you do crazy things, as some noir novel probably said.
queuebert··on Fish 4
Or "Revert back to C++" would be funny.

Apparently no one around here has a sense of humor, though, since my original post was heavily downvoted. I greatly prefer Rust over C++, but "rewrite it in Rust" has become kind of a meme. And if you can't laugh at yourself, who can you laugh at?

queuebert··on Fish 4.0.0
Heaven forbid you read a man page. Even though Bash is weird, it's fully documented.

I was expecting issue #9512 "Rewrite it in Rust" to have been submitted on April 1.
queuebert··on Part two of Grant Sanderson's video with Terry Tao on the cosmic distance ladder
He wrote his books as more or less first drafts. He had a lot of great ideas, but clear is not an adjective I would have attributed to his books.
queuebert··on 1972 Unix V2 "Beta" Resurrected
Depends on what you value. Purchasing power of wages has declined, for example. That's probably not better.

I suspect the sentiment is more that it would be nice to live in a simpler time, with fewer options, because it would reduce anxiety we all feel about not being able to "keep up" with everything that is going on. Or maybe I'm just projecting.

queuebert··on Siddhartha
How about "waiting to see which AI god emerges supreme"?
queuebert··on Gravitational Effects of Small Primordial Black Hole Passing Through Human Body
I agree. Absorbing 100 J (the paper's assumption) over an entire 75 kg body would be ~1.3 Gy whole-body dose, or 1.3 Sv for photons. That would probably make you sick. Traditional radiation therapy for cancer delivers 2 Gy/day x 30 days to the tumor to kill it.

What if mysterious illnesses like fibromyalgia are just PBHs? Hmmm...

queuebert··on Plane crashes, overturns during landing at Toronto airport
Doesn't look like a severe crosswind to me, because there seems to be very little crabbing or rudder input, although the camera angles make it hard to tell for sure. You can also see snow blowing on the ground roughly parallel to the runway. I would guess either a downdraft or they forgot to flare or both.

Boeing solved it by leaving the bolts out of the doors.

Unless you're a checked bag.

queuebert··on On David Lynch's Revenge of the Jedi (2018)
I'm happy to see the decline of the self-indulgent, cognoscente literary tradition.

I love words and language and reading, but rarely is expository writing the correct place for word orgies.

queuebert··on Record-breaking neutrino is most energetic ever detected
I was referring to the earlier monoenergetic flash. Yes, most should be produced through electron capture in the collapse, but for earlier event to be monoenergetic suggests a specific nuclear process to me.
queuebert··on Record-breaking neutrino is most energetic ever detected
That is weird. Is the conventional explanation a flash from one of the last fusion stages right before core collapse?
queuebert··on Record-breaking neutrino is most energetic ever detected
It's worth noting that we received the neutrinos from Supernova 1987a before the photons. We think that's because the photons have a difficult time escaping the ejecta cloud, while neutrinos stream away freely, but who knows ...
