As a landlord, I would not approve of this tomfoolery in any of my buildings.

Safety hazards I see include: Solar panels on the roof that aren’t bolted dow; I don’t care what wind speed they’re rated for. Wires running from them to the inside of the house not in conduit and not secured. A high energy battery pack not NRTL listed. Extension cords draped through the house permanently installed (within the expansive definition of permanently installed used by the NEC)

In addition running the wires in through a cracked window creates an unacceptable risk of water damage.

That said, it’s a cool project. Just do this in a barn you own not a house I own.

"Just do this in a barn you own not a house I own."

Someday we'll wonder why we thought it was a good idea to make the need for shelter into an investment vehicle. Until then, I hope people use your properties as they see fit.

Not every day a personally relevant story shows up. I've done work in that valley and with Billy. He's a special person and that valley is a special place. For many reasons. RMBL and Billy together are a beacon showing that science-for-the-sake-of-science can have long echoing impacts.

I think my favorite part about that place is that there is a vague tradition for scientists to turn over monitoring gear/sensors to Billy. And his house has become a improvised monitoring station much more than the manual measurements he makes every day.

RMBL and Gothic should serve as a prototype for what I wish every ecosystem had. It's deeply integrated with education of students, it allows and educated visitors, and the observations there will continue to serve the scientific community. I wish there was a network of things.

Absolutely, but for some reason pointing this out is considered massively classist in some quarters.

I don't really think it's classist to say that if people who don't value science, think climate change is fake, fear outsiders, etc. have 6 kids, and people who hold different have 1 or none, it will have a large impact on public policy in a generation.

You see, the thing is, it's deeply classist. It's also misplaced outrage. The poors have been doing this for millenia and we still have a society that progresses rapidly and much of the heavy lifting that moves us forward is done by folks you and others here are denigrating. If they believe the things you disparage it's because the governments and systems that the "smart" and wealthy have created have utterly failed at getting those people educated and involved.

Using your education to feel better than others doesn't serve us to advance as a society. I suggest that if you're as smart as you think you are then you find a way to frame the issue such that you're lifting up those people and not punching down.

earthscienceman commented on Safe and reliable production changes, and how Rivian recently got this wrong   blog.substrate.tools/safe... · Posted by u/kelp

I hadn't heard about the Volvo one! I had a 2022 Volvo C40 before I got my Rivian R1T.

When I first got the Volvo the GPS and LTE connection would periodically stop working for a day or two. They pushed a fix for it. Later they added CarPlay, which wasn't there when I got the car. Good updates. But not as frequent at Rivian.

Was Volvo able to fix it with another OTA or did people have to go in for service?

Imagine being rich enough to buy high end cars every year and worry about OTA updates. What a world.
earthscienceman commented on Stop using gitlab.com for projects – Credit card required for new registrations   old.reddit.com/r/opensour... · Posted by u/thepbone
earthscienceman · 2 years ago
Understandable concern, but this kind of fervor over this kind of problem feels a lot like the zealots who tear apart Firefox and it seems to be why open source community leadership suffers constantly. Is this good? Definitely not. But "stop using gitlab" and fleeing like rats into Microsoft's honey pot is like shooting off your face to spite your body.

I know, very clearly, that many HNetizens won't be using Github either. But piling on the hate train for these companies that at least try to support open source in earnest is doing strange things.

Every time my wife uses teams on 2.4GHz wifi our home network goes down. Works fine on 5GHz. Of course there is already a thread about this from 2020: https://techcommunity.microsoft.com/t5/microsoft-teams/micro...
earthscienceman · 2 years ago
Huh. Here I thought I'd totally lost my mind because every time I open teams on my phone it takes down my cellular connection. As in I can't use teams on my phone because it instant disconnects me from the Visible network. I thought I was losing my mind until I found other people with the problem.

Honest question, why does everyone uses discord for community space nowadays? What happened to product forums that could be easily found in a web search?
earthscienceman · 2 years ago
It's unnerving, especially for open source projects. The idea of open source extends beyond the license. It is as much about the community as it is the software. Discord is the worst possible place from an open-ness standpoint. I don't use software that uses it.
earthscienceman commented on The Geopolitics of Godzilla   petertasker.asia/articles... · Posted by u/jynxxx
shihab · 2 years ago
I also watched it last night, and it is my top pick for the year. It felt like a fantasy fulfillment film. For a nation with profound martial pride, the defeat in WW2 must have been a deep wound. But then there's Godzilla, an enemy that Japan can finally triumph over.

It's not a criticism. As long as the story is well-executed, who cares.

earthscienceman · 2 years ago
I mean, since this article is explicitly political and thoroughly interesting context I definitely have some criticism that I think should be stated here. I saw the film and it was very well made and enjoyable. A friend invited me and I didn't know anything about it before going in.

That said, there are clear problems with the political narrative in the film given it's supposed to be artwork. Making a film about redemption without in any way commenting on the evil atrocities you committed is extremely Japanese and morally dubious at best... downright propaganda at worst. Were the Japanese public and military rank and file the real victims of the war? Is it ok to pronounce the moral ambiguity of the top brass without commenting on the Holocaust-level crimes committed?

These things were glaring in the theater. And I know I'm going to get the standard "doesn't matter good film" responses for having an honest appraisal of the conceptual idea. But it's bad in that way. If we want to move into a brighter future we need both redemption and brutal honesty and this was only one of those things. Good popcorn film? Absolutely. Cultural artwork on a new level? Definitely not.

earthscienceman commented on Forecasts need to have error bars   andrewpwheeler.com/2023/1... · Posted by u/apwheele
lispisok · 2 years ago
A lot of weather agencies across the world run ensembles including US, Canada, and the UK. Ensembles are the future of weather forecasting but weather models are so computationally heavy models have a resolution/forecast length tradeoff which is even bigger when trying to run 20-50 ensemble members. You can have a high resolution model that runs to 2 days or so or have a longer range model at much coarser resolution.

ECMWF recently upgraded their ensemble to run at the same resolution as the HRES. The HRES is basically the ensemble control member at this point [1]

I'm someone working in the field with weather modelers/forecasters but not a modeler myself. Reading this discussion has been an absolute treat ...

The most fascinating thing about the concept of error in models, including in ensembles, is you can only calculate and propagate error for contributors that you can quantify. There are many unquantifiable sources of error. Imagine a physical process that you are unaware of that propagates as a bias, for example ice nucleation via aerosols. Perhaps you don't even model aerosols. How do you account for error here? What does error even mean?

Ensembles only show you intramodel variability. Which is like error, sort of, but only really represents a combination of "real" variability in initial conditions and how that propagates through your physics/parameterizations.

"models" the HN commentators make for their businesses surely have parallel concepts, but I don't see anyone talking about them. Only discussion about the errors you know when the ugliest errors are the ones that no one knows.
