    I’m more concerned about useless and damaging, performative actions against plastic.

    Of course what we need is plastic monomers that are neither carcinogenic nor hormone disrupters. We should stop dumping the stuff into the river. Poisonned blastic with bromine should be labelled in a was that makes it easy to identity. We should breed yeast that can east plastic and keep them in giesters.

    current plastics not biodegradable is the same problem that trees had for 300 million years. I think it’s a matter of time before some yeast evolves the ability to eat plastic. Then all plastic will start to mold and rot like all other organic matter.

    as for being “endocrinologal distruptor & a carcinogen”, yes so is a lot of other stuff, probably stuff in wood, again, like turpentine

    We’re not going to ban all plastics until some company has a proprietary alternative that they can force us to buy by making all other products illegal to produce. But that new alternative doesn’t exist yet.

    My advice, don’t eat electrical junction boxes

    The difference with leaded gasoline and asbestos, is that everyone everywhere was being exposed to those.

    And the current trajectory regarding PFAS is, a complete ban https://www.wcl.org.uk/transitioning-to-a-pfas-free-economy.asp

    But they’re not a problem everywhere, they’re a problem of containment at the manufacturer.

    This is what sloppy statements like plastics and teflon are tantamount to the widespread lead and mercury poisoning. That’s just not the case but acting like it is, is exactly how industry initiate regulatory capture.

    I see it the same as the big tech giants pushing hard FOR regulation, because ultimately the rules, written with their impetus will become their motes and we will all pay for it.

    That’s been well known for over 50 years, why do you think now, all of a sudden, this is becoming an issue now ? This is because there are new coatings, silicon based PTFE-free coatings and PTFE-based metamaterial that combine titanium, ceramic and/or PCD.

    As the manufacturer invest in this new technology, they either restrict PTFE commodity manufacturers out of their market or merely stop funding lobbying that protects the PTFE.

    This is not a conspiracy theory, simple emergent interests that do not require a coordination.

    Yes, I read about it and the teflon on frying pan is explicitely NOT the problem. I understand that pointing to frying pans and saying “PTFE !!” is the attention grabbing thing to do. But there is no danger here.

    The problem is the manufacturing plants leaking PFOA/PFAS into their surrounding environment !

    The PFAS/PFOA controversy, is mostly about banning these commodity products so that the proprietary, non-commodity alternatives by western companies can become the only high temperature dry lubricant on sale.

    Maybe in another 60 years we’ll have the same controversy about them !

    Plastic is an organic material, trees are mostly plastic (lignin, a phenolic polymer, cellulose a polysaccharide polymer, hemicellulose an heteropolysaccharide and suberin a polyester-like polymer).

    The problem we’re having is a naturalistic fallacy crossed with the unpleasant fact that almost everything we touch sheds dust and powder absolutely everywhere. This along with spores and yeast and other dusts constantly enter our bodies.

    Plastic is only of note because we made it.

    Any problems beyond that is speculative and will requires ginormous gobs of grant money to actually answer with anything than precautionary principle-based FUD.

    Except plastic doesn’t really seem to do anything. It just “is there”. Unless you swallow enough of it to clog something, it doesn’t seem to do anything.

    We’ve seens lots of “it might interefere with hormones”, but that part is always to be confirmed in the next research grant request and then we never hear about it again.


  • Thanks that looks like the most attainable way for now. But I would like to have more data in there, such as season temperature trend, 10th and 90th percentile historical values and min/max temperature records, to give context to the data. Also have precipitation. Be able to zoom in and out of the data to get more find grain minute-by-minute, or see the last 5 years at once, and be able to move the “X” position in time, so that I could watch the data, at the minute level, but from 4 years ago. Also I would hope to see the 7 day temperature prediction line

    Like this, where the yellow line represents “now” and to the right is predictions


  • This looks good, although I’m not a fan that it says “non-commercial use” To me that means, we reserve the right to alter the deal. Also it seems to get it’s data from a private company, rather than my local government weather office and their public API, whatever it might be ?

    Also, this says it is an API. So would I need to code up an entire web front end to display the data like I would like … ?

    I presume, there is some application which can display data of this API ? Are any, like the style I am after ?

    I see that it has the historical data so that’s great, maybe I could have the min/maximum recorded temperatures as part of my single temperature view thing, at least, it could do it !

    I see there is a 10000 API request limit, so I don’t know if that’s going to work at all. If I just scroll back in time, I imagine it would bust this 10000 request cap very quickly ?

    But that does sound like the most promising meteo self-hosted option.

    It’s kind of weird we’ve got maps, mail, notes but not weather ?

    There are so many people making their own weather stations but it seems here there has not really been someone self-hosting their own weather dashboard !

    Maybe it’s a new frontier of selfhosting !
