The deepest shipwreck was found last year: https://www.guinnessworldrecords.com/news/2022/7/worlds-deep...


Wow, I wonder how this will affect phosphate and fertilizer prices.


It should have no effect on fertilizer or phosphate prices, because it is a cheaper method to produce certain organic compounds of phosphorus.

Phosphate is used as an input for these chemical processes, but the fraction of the phosphate production that is used for such processes is very small in comparison with what goes into fertilizers.

The only possible effect is a price reduction for some organic compounds of phosphorus, e.g. for some pesticides.


Also, came here for the fertilizer info, as I believe P deposits are getting more expensive? (happy to be corrected)


I don't know about costs but phosphorus is a limited resource and more than 70 percent of the world's supply of phosphates is controlled by one country: Morocco.

Some estimates put "Peak Phosphorus" as early as 2030 but unsurprisingly, that claim is highly contested.


They are occupying the space left behind by human activity. Chemicals will only create more resistant strains just like it did with Amaranth. The reason these plants are successful is the horrendous landscaping traditions especially in new developments. The use of chemicals only reinforces these plants. Basically what's happening is these strains are put under so much pressure in the urban environment that they becomes "super-weeds" and then invade the rest of the landscape. It might be too late to do anything about it now.


I don’t think stinknet requires cleared land. Vegetation in the Arizona desert doesn’t form an unbroken canopy. Water is the limiting factor, and stinknet is apparently more efficient than any native plant at immediately converting water into explosive growth and immensely prodigious seed production.

It may well be that the natural course for stinknet is to dominate all other desert vegetation to such an extent that it forms a monoculture that fails to maintain ground nutrients and creates evolutionary pressure toward symbiosis with native plants. But it could take a hundred thousand years for Arizona stinknet to become a good citizen.


It does not require cleared land. It will grow under other bushes and trees and pop up right in the middle


More likely some grazing animal figures out how to digest it first.


climate change.


Good stuff. It would've been nice if there ever was an actual "Next Step" tensor that once multiplied (or some other operation) by any tensor representing current state, would give you the next state. That was my initial thinking when I read "Using Linear Algebra".


Are you asking for the Hamiltonian of the Snake world? I don't think it exists. The transformation is non-linear :P


It exists in theory, since Snake (like all computer games) is a finite MDP.


Yes, but not in the matrix state we are using to represent it. It would probaly need to be represented as a "one-hot" MDP encoding, takes away from some of the beauty of it.



My understanding is that incinerators don't just release the output. The exhaust is pumped back into the system and dealt with somehow. The extent to which the release is "dealt with" is the tricky part.


I'm going to guess that large amounts of CO2 is a byproduct and is vented.


CO2 is bad but not toxic at all. It's inert. The toxic ones are toxic because they still have some energy left and the earlier you pull out that energy the better. Preferably in a plant that puts that energy to some form of use.


Have you been under a rock for the last 20 years?


Another eclectic fractal is this impossible 3D triangular one which seems somehow connected to sheaf cohomology.

My first reaction to "Design and Prototyping" was asking "Of what?".


There's a tendency here to assume all words refer to software. I've seen people referring to software tests as "harnesses". No, fucker, I make test harnesses. With wire and terminals and a crimper. The result is a physical wiring harness, so called because it has wires bundled and routed according to their function, the literal definition of a harness. It connects to the device under test so we can test it.

My optimism that software people will put the word "software" on words they borrow from other things that still exist, never fails to bite me in HN headlines.


Sorry, you seem to have some kind of reason for believing a hardware test harness is more valid than a software test harness? Can you explain? Aren’t both just two types of harnesses?

Also a bit amusing since harness is obviously a term borrowed from something else that does already exist. I hope you’re always clear to say “hardware test harness” in case any equestrians are nearby and start ranting about hardware devs never being clear!


Speaking of that, equestrians actually love saying the word "racing" like they own the motherfucker


Grab any dictionary. Look up "harness".

Now what?


You can make it using Cellular Automata too.
