I dug several mm long glass shards out of my Schwalbe Marathon+ without them penetrating to the tube, but if you want solid rubber, you can buy it: https://tannus.com/tires/

Thanks, this sounds great. But 2 tires cost more than my whole bike :/ Not that I can't afford it, it just feels wrong somehow :)

Just compare it to car tires and it doesn't sound so expensive anymore :)

Why not? If it's the time and place to praise him, then so is the time to point out his wrongdoings.

It's just tedious virtue signalling, rather than a contribution to the thread. We all know he did things that are considered abhorrent when viewed against the current, moral zeitgeist.

Sure, let's just starve your family to death and then laugh about it and see if you only consider it "abhorrent when viewed against the current, moral zeitgeist". It's amazing how people will not only downvote, but flag the posts here that go even a teensy bit against their propped up beliefs. And I thought the hn crowd was supposed to be discerning.

Not enough people are tunnelling their way out of prisons to justify the expense of building prisons out of anything like this. And it's too bulky for shutters or fences. Safes and vaults might be a good application.

Jail and prison are not the same thing. Jail is for light crimes - most people in jail leave every day to go to work, and then return to jail when work is over. It is easy to run, but odds are they will catch you (they know your family, job and friends...). It isn't uncommon for the windows to open without triggering even an alarm.

Prison is a level higher. You start out in a more secure setting where it is harder to do anything without getting caught. (if you only get 1cm of tunnel built it doesn't do you any good). If they suspect you are going to pull anything they move you to more secure prisons where you are watched closer.

You might be smart, but there have been lots of smart people in prison before you with nothing better to do than dream up every possible escape plan. They are gotten good at detecting and preventing them over the years. In short odds are against you getting out successfully, and the attempt will earn you more time in prison.

Prison cells (whose rooms are cast concrete over rebar). AT machines. Vaults, safes... Lots of things. Roll-up shutter doors... fences around construction equipment.

What construction equipment could possibly need an indestructible fence surrounding it?? Most construction sites have chain link or orange plastic fences, and they’re not to prevent theft. You hire security or insure the equipment against theft to protect against theft. Anyone that owns heavy equipment carries insurance covering damage, theft, and liability. Otherwise it’s rented and Sunbelt or whoever is on the hook…

The fence is to keep 5 year olds out. As the parent of a 5 year old I'm not sure this is strong enough to do the job.

Seconded. This could have been written by Churchill.

Actual Churchill quote would be "My dear you are inedibly bitter, but tomorrow I shall be sober and you will still be inedibly bitter."

Not Churchill, alas. https://quoteinvestigator.com/2020/06/28/drunk/

Absolutely. I also have a pomelo tree, though it's still in a pot in the shadehouse, and produces a single (enormous) fruit each year. Grapefruit are a cross, probably, of pomelo and a sweet orange - as you say, not all that long ago. While some grapefruit varieties are quite pithy, pomelos (that I've seen) are very pithy - hence the 'this can only have been even more expensive a protective layer in earlier versions…

Interesting. There are other fruit & seeds out there that develop strong exocarp or mesocarp (think coconut) and I believe it has to do with wanting the fruit to travel longer distances to encourage geographic spread. The plant probably "prefers" that the seedlings take hold some distance from the parent, so wants the seed preserved longer and taken away by certain kinds of animals (hairless apes!) What kind of anima…

All I'm finding is 'south east Asia' as origin -- which is an enormous range of fauna.

I understand the 'travel far and wide', though of course evolution's not directed, and is there significant difference in fitness & success over the long term for a variation that allows a plant to produce offspring 1km away in one generation (say 5y), rather than taking 2 generations?

(And, of course, it's worse than that. The 10m drop potential isn't realised until the plant is probably 15 years old or more -- at which point the distance / propagation calculation is almost irrelevant, as that specimen would have produced fruit for at least 5 years whose seeds would have travelled the same distances, regardless of this (future) robustness capability.)

Sadly, though, I suspect plant archaeologists have more pressing concerns than this question.

Thanks dang, I understand and appreciate you pointing this out. However, I would say the original flamebait and a tangent was mention and praise of a person who has committed well documented genocide. So I don't see why my comment is the only one being flagged for pointing this out.

It's a joke.

I don't claim to be especially smart, and even if i were it does not neccesarily translate to 'succes in prison' or tunneling skills.
