Time to read up on this and AWS Batch!
carbadtraingood··on OpenDroneMap
I use ODM to map large areas (100-300) acres regularly. It's pretty much fire and forget on AWS spot instances.

Combined with Dronelink, my workflow is largely automated. Just a few more pieces I'd need to have in place to be able have it be more or less hands off.

The next piece I want to tackle is creating a watched directory or S3 bucket that automatically spins up a spot instance, monitors for the completeness of the work, downloads the results to S3, and shuts down the spot instance. Then all I'd have to do is watch the drone fly and move photos into a folder.

It's great, but several times it does fall back to single threaded performance. I regularly use it to generate photos of hundreds of acres, and I end up needing a machine with more RAM and less CPU.
carbadtraingood··on Amazon instructs New York workers “don't sign” union cards
I did, during the initial union busting efforts. Surprisingly easy to get by without prime.

Until Amazon can start treating workers well, it seems to me the best move is not to pay them to abuse people.

carbadtraingood··on People with low BMI aren't more active, they are just less hungry, 'run hotter'
Do you run cold or feel cold? Because those are opposite. If you run hot, temperatures should feel relatively chilly. Like when you run a fever you feel cold.
carbadtraingood··on It’s time to make that indie C# game in Godot
Sonic Colors remaster, iirc?

The games in that showcase look pretty decent to me? Plenty of games I play look like that, lol.

carbadtraingood··on Corn Cobs: Fuel of Nightmares
Totally. I am currently experimenting with TLUDs for waste products from some forest land I own. I didn't realize they were also attempting to capture the gases from pyrolization rather than using them to continue the pyrolysis.

In that case, you are totally correct, they'll need an input heat source.

carbadtraingood··on Corn Cobs: Fuel of Nightmares
Yes. And also no. Practices like that are good, but the majority of your carbon sequestration will come in the form of the roots of plants. (This is part of why no till is good.)

Getting surface vegetation to deposit carbon in the soil long term is trickier. You aren't wrong, but it's also not as simple as some folks believe. Just cutting the corn stalks and cobs and leaving them on a field won't put much carbon back in the soil.

carbadtraingood··on Corn Cobs: Fuel of Nightmares
Right now I'm experimenting with biochar production in small scale TLUDs, but I'm absolutely fascinated in scaling up.
carbadtraingood··on Corn Cobs: Fuel of Nightmares
It's the same way that burning 1 kilogram of gasoline produces more than 1 kilogram of CO2. Oxygen from the atmosphere gets bound to the carbon.
carbadtraingood··on Corn Cobs: Fuel of Nightmares
Wheat straw is a common agricultural waste product across the US, and if they can solve processing that they still win. It's not that they tested A for a product that will only process B. They tested A for a product that will eventually process A and B and C and...

Scaling up means testing with new inputs at scale. So now they've done that?

carbadtraingood··on Corn Cobs: Fuel of Nightmares
Pkrein, I see you posting here. I've got 200 acres of forest in Washington State and I'm long term interested in providing biomass for carbon sequestration, what can I be doing now to connect with companies like yours to help ensure those 200 acres are as carbon negative as possible?
carbadtraingood··on Corn Cobs: Fuel of Nightmares
Pyrolysis is an energy positive reaction. It requires an initial heat input, but after getting started it produces more heat than it needs. That heat can be used to generate electricity or warm water.
carbadtraingood··on Corn Cobs: Fuel of Nightmares
Decomposing biomass releases almost all its mass back as CO2 into the atmosphere, very little is sequestered.

This approach removes carbon from the atmosphere permanently.

It's also (probably) a net energy producer and it doesn't require creating massive piles of decomposing plant matter everywhere.

carbadtraingood··on Corn Cobs: Fuel of Nightmares
They discuss a bit in the article, but the material they had prototyped with was very different than the material they tried to scale up with.

It sounds like their scaled up plant accepted a wide variety of materials, but this one specific input stream slowed them down.

So they weren't shut down while they figured this out, they just processed the material they knew they could process until they had a solution here.

carbadtraingood··on Woman ‘dehumanised’ by viral TikTok filmed without her consent
Do you have quiet times where you collect yourself? Get lost in your own thoughts or read a book?

Imagine me coming up to you during those times and interrupting them, while secretly filming your response.

You find out later you've been filmed, and that the person who interrupted you is getting paid for the footage they collected of you without your knowledge.

Millions of people have now seen how you react when interrupted, and are leaving comments about how much you look like you "needed" interrupting. Maybe a coworker or relative sees you.

carbadtraingood··on Woman ‘dehumanised’ by viral TikTok filmed without her consent
She's not being treated as a human, she's being used as a prop. There are many levels of dehumanizing, and treating your subjects like objects rather than people is a form of dehumanization.

Bees don't steal anything humans want. Nectar and pollen are not something we collect ourselves. The bees, however, do pollinate the plants that provide us with food, so keeping bees can increase yields for neighbors who are growing things.

That was me two years in. Check back in another four.

Ford lighting is currently my next vehicle, but we have a need for a truck specifically (we have forest land we work on conserving).

I'm keeping an eye on Kia, VW, Hyundai right now. But I expect other manufacturers will catch up.

carbadtraingood··on You can’t eat just any leaf (2018)
An acre might be low, five acres might be high. Depends a lot on what the local conditions are like, what you can grow, what tools you have.

I keep bees, for instance, and my hives produce about 50-100lbs of honey per year. It's not super nutritious, but it's low effort per lb. Ten hives could produce a lot of raw calories. But it's also a skill, and you can kill your bees if you aren't careful.

The point I'm making is that, we're all bringing different skills and backgrounds. I've grown potatoes but never at the scale of an acre. I don't know what challenges that brings.

carbadtraingood··on You can’t eat just any leaf (2018)
Borage, miner's lettuce, nettle too! To say nothing of the berries you can snag from things.

That said, we do grow kale, as it's a pretty nutrient dense green that is mighty tasty, versatile, and hard to mess up.

carbadtraingood··on Andrej Karpathy leaves Tesla
Yeah, I have an older model S. It could be my model just doesn't get the care that newer ones do, and my experience reflects an "early mover" experience. But I've had to replace door handles, sensors, memory, windshield, and a bunch of other stuff due to defects. The car stutters on the road at 50-55 mph, but is fine above that.

It was awesome in 2015. It's a pain in the ass in 2022.

carbadtraingood··on Andrej Karpathy leaves Tesla
But there are great electric cars from, eg, Kia, Hyundai, Ford, VW, etc. Etc. Tesla is no longer unique.
carbadtraingood··on Andrej Karpathy leaves Tesla
Currently have a reservation in for a Ford Lightning (but we use a truck for our forest). We have a plug in hybrid that has a 20 mile range on battery that basically never runs on gas as well.

I've heard good things about the Kia Niro, VW ID.4, and Hyundai Kona as well.

carbadtraingood··on Andrej Karpathy leaves Tesla
The cars are real but they are... Mediocre. The first year of ownership is an amazing honeymoon period, assuming you got one with decent build quality. But the parts are cheap, and they break quickly. I've had one for 5+ years and it's gradually become something I prefer driving less and less.
carbadtraingood··on Andrej Karpathy leaves Tesla
As an owner for 5+ years, the cars show well but pretty quickly become a pain in the ass.

They'll get eclipsed by other electric car manufacturers real quick.

Edit: more specifically, the parts break and they are difficult to replace. The battery degrades. They stopped providing maps to the vehicle unless I'm willing to spend several hundred dollars to replace the media console, they've told me I'm covered by a recall/warranty but have been unable to schedule the appointment.

carbadtraingood··on Inflation rose 9.1% in June, even more than expected
I know plenty of folks who this describes? FAANG workers who got in at 20, no kids, own homes and have hundreds of thousands in the bank.
carbadtraingood··on News engagement plummets as Americans tune out
In the States, yes. It's unfortunate, I think, because it lumps together many different (and often opposing) ideologies under one label.
carbadtraingood··on News engagement plummets as Americans tune out
Yeah, that makes sense to me.

I think I probably care more about defining "left" vs "liberal" then most here in the States.

And I'd agree, as much as I want it to be the case that we see more worker solidarity, it's not the thing most Americans seem to think about. Even if they have concerns about current policies. For instance, Americans could call for a general strike as a response to the Roe v Wade decision. But the idea of using worker power in that way seems quite alien here.
