BBC 4 on Long Wave.
wonderful signal on 198 khz.
It is also a good signal to use for frequency calibrations as the carrier is derived from a Caesium reference.

Only 639 years?
It would take approximately 1.3m years to ring every permutation of the 16 bells in the tower of the church of St Martin in the Bull Ring, Birmingham, UK.[0] I'm not sure the bells, tower or ringers would last that long though, get there early to avoid disappointment.

wouldn't that create a recession or depression?
We could go for ecological and climate collapse instead.
I hope there is a middle way.
I was once at a Plump DJs gig where the fire alarm went off and it took everyone a minute to realize it wasn't part of the tune.
I've also heard of people dancing to a generator when the hardtek stopped.
To be fair to the people concerned, both examples actually match the style of the music in question.
Reminds me of the hardcore raver Tyres from the sitcom Spaced (genius British comedy):

Saying that I have had a similar thing with tracks that have police sirens in them when listening in the car, it takes a moment to realise it isn't an actual emergency vehicle.
PoachedSausage commented on Ask HN: What was the biggest leadership challenge of your career? · Posted by u/mparkola
Are you preparing for an upcoming interview?
It is the annual creative writing exercise known as appraisal time at many organsiations, including mine. Why not get some inspiration from HN?
Actually this year has never been easier for appraisals, all successes have been despite the great covid challenges, all failures and delays are due to the terrible covid disruptions.
I feel like claiming it is "working" and "3d printed" are tenuous at best.
It did work... for several seconds before it melted.
It was 3d printed... except for the turbine, shaft, bearings, and combustion chamber which were made of metal, and the structural components which were cast from ceramic.
Also, FWIW, the description of the how the turbojet came to be at the beginning is pretty grossly incorrect. It is sort of like how in grade school they say that planes fly due to the Bernoulli's principle. If you are interested to learn about how jet engines actually work and the technical details that go into them on youtube, I highly recommend AgentJayZ [1]
If you want to see a youtuber make an actually good turbojet, check out these channels:
-Игорь Негода [2] His videos are in russian, but are by far the most technically advanced and performant. I watch them with the auto generated/translated subtitles
-Tech Ingredients [3] This is a traditional turbocharger based design, but is presented in a wonderful way packed full of interesting tech details
-Colin Furze [4] The turbojet that inspired this video. Much more focused on presentation than tech details, but worth watching for the comedy at least!

What is wrong was the immediate jump from "Fat in organs is the fat we eat from food". It seemed a natural and simple explanation at the time.
Now it appears it's not that clear. It's the excess of sugar in everything that overloads your bodies temporary stores of glycogen in the muscles and liver, which is then stored as fat, since your body can easily transform sugars into fats.
To see how that looks you can track the obesity numbers in US, the more "0%!" fat products are propped up with suger over the years, the larger the obesity crowd.
I don't think the final word is out yet, but the _cause_ of fat in your body, is not necessarily the fat that you eat.
Did people really believe that dietary fat was stored by the body without any kind of biological processing?
If you examine it from a thermodynamic perspective (I know that is simplistic for human biology), weight for weight fat has double the energy density of sugar, 38 MJ/kg vs 17 MJ/kg according to [0]. For reference, gasoline and diesel fuel are around 45 - 48 MJ/kg.
Also, according to [1], dietary fats are broken down to generate acetyl-CoA which is the precursor for lipogenesis (fat storage), therefore eating fat does not necessarily make you fat but consuming a lot of it and not metabolising it to do work will make it easier for you body to store fat.
Do you have a reference by chance? Would love to dig in a bit. I know that high sugar consumption raises triglycerides. But haven't seen anything yet on cholesterol.
A good start:

Plywood was used for shields by the Romans, I'm fairly certain the Vikings, and wikipedia mentions the Greeks and Egyptians used it as well. From what I can tell from a quick google, it does seem to be a casualty of the Dark ages though.
Maybe not. The Dutch police appear to be using wicker riot shields in 2021. Good for the environment.

PoachedSausage commented on Have we already been visited by aliens? newyorker.com/magazine/20... · Posted by u/elorant
I thought the idea that there are gazillions of advanced aliens has been pretty much disproven by the fermi paradox.
If there are gazillion, at least one out of all the diversity out there should have already colonized the entire galaxy and evidence should be plentiful.
Maybe there has been some sort of accident of scale, like the intergalactic fleet in Hitch Hiker Guide to the Galaxy that arrives to destroy Earth but is eaten by a dog.
There could be a banging ET party going at the Planck scale and we would never know, they might as well be on the other side of the universe.
