- Comment on How Fossil Fuel Disruptions Lead to Booms in Solar and Batteries 13 hours ago:
Gigantism in mining trucks like Belaz 75710 www.lectura-specs.com/en/model/…/75710-11738579 with 360 tons and 1.7 MW diesel-electric hybrids – which frequently run 24/7 is due to ore grade depletion. You might want to run the numbers of how a sodium-ion mining truck would look like, and how long it would have to recharge. Notice the tires, they’re made from at least partly synthetic rubber. What you don’t see is lubricants, also synthetic. Polymers, synthetic. Notice the amount of structural steel.
Solar PV with battery buffers (necessary for 24/7 industrial processes) has ERoEI of less than 4 which is insufficient to maintain a complex industrial society. You can try to substitute some of that with small-batch fast (running just during the day or whenever the wind blows) processes, but that will be the minority.
You mention horses a lot – these will be needed again, after the industrial age. And slaves, and ships made of wood. Which will do fine in a world with maybe 100 million people. Maybe a lot less.

We know if fundamentally feasible, photosynthetic organisms can do it with just local resources, with reasonable replication rate and some excess sufficient to sustain the global ecosystem.
However, we don’t know how to do that, and, worse, we have stopped pursuing that development route. Some dream that we’ll get general artificial intelligence Real Soon Now which can bootstrap molecular nanotechnology in a short time frame that we have left.
Could happen, but that probability is pretty damn low.

We’re already past primary energy use peak per capita, and we’re distinctly past net energy use. At the same time, extraction of increasingly dilute mineral resources necessary for technology requires progressively more and more energy.
So I would expect we start losing fossil inputs quickly, since increasingly unable to extract them, while the renewable infrastructure will not have grown sufficiently, and then starting to decline, since we cannot sustain them with renewable energy alone.
At the same time we’re going to lose a lot of population (excess deaths of several billions this century), so at least whatever resources are left will last longer than at the current use rate.

No, while biology (self-rep ISRU with mostly CHNOPS) shows it’s feasible, it’s a hard engineering problem – which is not even on our radars yet. And the hour is very, very late indeed.
- Comment on OPNsense Mini PC Suggestion + Switch + AP? (And running cables) 20 hours ago:
Look at protectli, there are equivalent devices on aliexpress if too expensive. If you’re particular about open source, try finding ones with openboot.
Use a PoE switch, or a power injector for AP. If open source, OpenWRT APs.

Thing is, there is no energy transition. Renewable infrastructure, built using fossil fuels is stacked on top of rising fossil energy use i0.wp.com/…/World-energy-fossil-fuels-vs-add-ons.…

There is no workaround for proprietary platforms other than stopping using them.

I understood OP already has one.
Motorola, yes, but that’s 2027, or thereabouts. As a stop-gap, there’s Lineage OS.

It’s not changing, look at the industrial fabrication and supply chain for solar PV and wind. None of that is powered by renewable electricity.
Renewable infra are a fossil multiplier (but not by much), but the total fraction of fossil in primary energy use is effectively constant, because use of fossil fuels is also increasing.
- Comment on How Fossil Fuel Disruptions Lead to Booms in Solar and Batteries 1 day ago:
News flash: you need fossil fuels to create and maintain renewable infrastructure.

- Comment on Your car’s tire sensors could be used to track you 2 days ago:
They can ask for an expertise after a car crash, if it’s worth to not pay out, or if there’s something they deem suspicious.

Mitsubishi ASX.

This was a tip to OP, in case he wasn’t aware. Insurances will use any pretext to weasel out of their contractual obligations.
- Comment on Your car’s tire sensors could be used to track you 3 days ago:
I made sure my car doesn’t come with a cellular modem. But I didn’t knew about the pressure sensors.
- Comment on Your car’s tire sensors could be used to track you 3 days ago:
Your car insurance might be interested to know this fact.
- Comment on Your car’s tire sensors could be used to track you 3 days ago:
Unfortunately, I do. And they lock you in to licensed vendors just for your seasonal tyre change.
Looks like my next car is going to be an antique.
- Comment on Motorola confirms GrapheneOS support for a future phone, bringing over features 3 days ago:
Reproducible builds and lack of telemetry, plus hardening against compromise (by any actors) is my personal use case. I only run free/libre infrastructure privately, and hope to move on to open/libre hardware in future.

With a bit of infrastructure, today you can detect and disrupt any VPN session. This is coming soon to your country, too.

These guys are actually begging for it.

The Internet is just a bunch of AS running open source protocols on commercially available infrastructure. It’s doing fine. The hosted commercial services might be fucked, but you can run your own.
You’re using such a service right now.

The failure rate is high for ML GPUs. The hardware is effectively consumables.

You can’t do much with them, unless you’re into deep leaning. And the power bill would bankrupt you. I wish I had a Cerebras box, but even the smallest one is 20 kW, liquid cooled.

HBMx is a different product than DDRx/GDDRx, though parts of the fabbing are probably shared.
