FYI - The actual BBC title is “Cherry Kearton: The eccentric influence on a young Sir David Attenborough” but I felt this wasn’t descriptive enough.

The article subtitle is “As a child, Sir David Attenborough was transfixed by the work of Cherry Kearton, a photographer and filmmaker who almost single-handedly changed the way we view the natural world.” which I tried to use but was way too long, so I abridged it.

Copy Fail 3 months ago

This submission is currently the main HN submission.

As of now the submission title is simply “Copy Fail”.

Given the severity of the exploit, can we edit the Title to add some context that it’s a major Linux vulnerability?

Eg the other submissions say this : “Copy Fail: 732 Bytes to Root on Every Major Linux Distribution.”

Why Not Venus? 3 months ago

This is a terrible take, and I say this having a PhD in Physics.

Many physicists have written popular articles and books for the general population. Eg Einstein, Stephen Hawking, Brian Cox. Improving accessibility of advanced concepts is nothing to scoff at.

I did a bunch of research on similar Tc superconductors back during my PhD.

7K is considered “warm” from a cryogenics point-of-view because you can just dunk your sample into a dewar of liquid helium at 4.2K. You can even get it cooler, down to about 1K, using evaporative cooling techniques. [1]

It’s getting to lower temperatures than this when things start getting complicated. Eg a closed-cycle evaporative He3 system can get you down to 200 mK, or you can bite the bullet and use a dilution fridge down to around 10mK.

Does annybody worry about sabotage if you don’t tip? Eg the cashier does something to your food? “Nice muffin you got there, I’d hate for it to get accidentally sneezed on.”

I recently bought my mom flowers for her birthday. Despite the price showing no delivery fee, the final price included $15 delivery charge, $8 service charge, taxes, and then asked me for a tip.

I chose no tip, expecting the delivery and service charge should cover everything.

The flowers were left on her front porch in below-freezing weather, they didn’t even knock or ring the doorbell. Luckily my mom happened to open the door and saw them before they completely froze.

So was the delivery person incompetent, or acting out because I didn’t add additional tip?

Two thoughts on situations where the 555 may be preferable, if anyone has experience how these compare :

1. Low-noise applications. I’d naively expect the 555 to be less noisy than a clocked digital microcontroller, though it’s been awhile since I’ve worked in this space.

2. Low power applications. How does latent power draw compare between a 555 and a typical low power microcontroller?

At my cousin’s company there are TV’s in the lobby.

They used to show news channels.

He said clients would come in all stressed out. So they changed to a home improvement channel.

Even in your own car dropping off your friends or family at a UK airport (at least the London ones) requires paying a £6 fee now. Just to get to the dropoff area, even for 30 seconds as you say.

But hey, at least the luggage carts are free…

They’ve been doing this for over a century, it’s probably the top deaf school in the UK, and has the support of nearly the entire deaf community.

Most of the students have either some degree of hearing or use cochlear implants. I think nearly all, if not all, students use either hearing aids or cochlear implants.

The classes are very small (eg 5-6 max usually), students are arranged in a U-shape around the teacher so they can read lips. And there’s a special wireless broadcast system so the teacher wears a microphone and sends the audio directly to hearing aids or cochlear implants.

Regarding deaf culture, most of the students use BSL on their own outside class, and my daughter learned BSL from her friends there that grew up with it. Coming from a mainstream primary, she found “her people” here, discovered deaf culture and a community that shares the same struggles she faces.

The idea is that by teaching in BSL the students are further restricted in their ability to function in a hearing society.

I’m curious if you are deaf yourself, or work with the deaf. All the teachers at the school are trained teachers of the deaf, some are even deaf themselves. And I haven’t heard any complaints about the aural nature of the learning (except from the reservations of a few parents before sending their kids there, and I don’t think any of these parents regrets this after their children started there.)

This was going on long before LLMs.

When I took quantum mechanics in grad school, I struggled through the weekly (and intense) homework sets. My TA was a hardass, I’d spend hours on some problem, several few pages of math work just for one problem, and make some dumb mistake in an integral somewhere, being off by a factor of 2 at the end and only getting 2 of 4 points.

It was painful, and I felt like a dumbass seeing the other kids regularly getting perfect scores.

Then the midterm came and I blew them all out of the water. I hadn’t realised they somehow had the solutions manual so just got perfect scores all along but clearly didn’t learn the material like I did.

The “expected distance” is not what you think here.

For a binomial distribution of probability p and (1-p), after N steps the expectation value of right steps is Np.

The Variance is Np(1-p), so the standard deviation (or Root-Mean-Square) scales as Sqrt(N).

Rob Reiner has died 7 months ago

He was also brilliant as Michael “Meathead” Stivik in the phenomenal TV series “All in the Family”.

Amazing how many classics he worked on throughout his career.

A few people I know had moved to houses on one side of the bridge for easy access to schools and jobs on the other side, and were hit hard by the closure.

Their commute times skyrocketed to go to the next Thames crossing.

To be fair, this issue isn’t endemic only to big companies. I’ve seen similar even in academia, some people just know how to “play the game” and play it very well.

It really depends on the culture of where you are, which can even vary team by team in the same org.

I don’t understand the seeming lack of regulation for flashing bike lights.

I don’t mean a simple “normal” flashing light, but the super bright ones that are like a camera flash strobe going off 2-3x per second which hurts your eyes and kills your night vision, making it hard to see anything including the actual cyclist.

Title is a bit misleading - it's not pure germanium that superconducts here, it's germanium doped w/ Gallium atoms.

Superconducting germanium alloys have been known for decades, I used a Molybdenum/Germanium superconducting alloy in my PhD research 20 years ago, with much higher Tc.

The interesting aspect of this current experiment is the precise alignment of the Ga atoms into specific points of the Ge lattice, so preserving the crystalline structure order which leads to some interesting effects.

The sheer irony of your unwarranted pedantic critique of the usage of “next” is that all HN threaded comments, including yours, have a “next” link in their headers which clearly does NOT refer to unwritten future comments.

Not sure why I bothered responding to a troll.
