Yet another Reddit refugee from the great 3rd party app purge of 2023. This account is mostly for learning how Lemmy works and may be purged once I get around to hosting my own instance.
Obligatory fuck /u/Spez.

Of course they are valuable. But corporations will always prioritize that which generates value for themselves.
What good are those massive improvements to gaming cards when GPU costs spiral into the multiple thousands of dollars and become completely unavailable to 98% of gamers? 'Cause institutional buyers have no qualms dropping $20k per card, and that will inflate the market to an insane degree. Jensen knows this and will happily kick individual consumers right into the firepit.
110K (-163C, -262F) is still a significant improvement in cryo temperatures required for superconductivity. It no longer requires liquid helium temperatures for things like MRI magnets. So even if this is not a “holy grail” room temperature SC- it still enables the use of much cheaper commodity cryogenics like liquid nitrogen for use in scientific and industrial superconductors.
I know a little about stuff.
Similar to the 2022 firing, The fusion charge itself was net energy positive. That is, the fusion production was greater than the input of laser shot used, which means they’re closing in on optimal ignition.
However: the total cycle energy was terrible. The lasers NIF uses are quite old due to the speed of government and the sheer size of the project, plus thermodynamics hates an engineer’s guts. so their total real input electrical energy to generate such a laser pulse of a few joules was hundreds of thousands of times greater than the actual fusion output.
This is great for understanding the physics of conditions that fusion requires, but terrible for generating power.
ah, you’re worried about the bass being overpowering in some voices.
Most subwoofer amplifiers have a +12v trigger wire that must be connected to the radio so that the amplifier knows when to turn “on”. Otherwise it would drain your battery constantly. It’s pretty simple to add a toggle or push button on/off switch inline with that trigger wire so that you can choose when you want it on or off.
most amps also have a configurable lowpass filter that lets you select the cutoff frequency for the sub, so it will not drive any frequencies above that. Generally setting it to 120hz or less will make it not react to most voice without needing to turn it on and off all the time. I run the 12" 400w sub in my old Honda around 90hz cutoff, as the speaker really can’t effectively drive anything higher than that, and it leaves basically all vocals untouched.
Yeah. The issue has never been actually doing it, because chemistry is chemistry and all chemical bonds can be broken- it’s the economic viability, because breaking chemical bonds in hydrocarbon polymers is incredibly energy intensive. Energy that, up until now, would have also been coming from petroleum or fossil fuels, so you’d end up with a net negative. Thermodynamics hates an engineer’s guts and makes his life hard.
However those economics might certainly be changing as oil supplies gradually tighten and extremely cheap peak solar electricity becomes much more plentiful. Once midday electricity becomes an almost waste and the energy is cheap, the economics of processing becomes a lot more attractive.
Human TL;DR- they’re breaking ester bonds in PET via hydrolysis into it’s base components. Theoretically they’d be easier to separate at that stage and reform into brand new PET. But it’s only in lab reactors, not scalable, and most likely excessively energy intensive for the total material processed (as electrolysis almost always is), and such is a fluff article
I think so. Since it supports proper NVME drives it should be compliant with the rest of the pcie spec. It is only a pcie 2.0x1 lane on the 3588S, so not roaring fast, but it still beats the pants off usb3.
I don’t have an m.2 to slot adapter but I do have a couple m.2 wifi cards floating about. I may try to put one into the board and see if it works and report back.
Edit: I just looked on their website. Under the m.2 slot it lists
“Support PCIe NVMe SSD Support custom PCIe Wi-Fi6+BT5.0 module”
So yes- it should be fully pcie complaint. Not fast, but usable, if you can get arm64 support from your driver.
Edit edit: the orange pi 5 “plus” has the 3588 (non-S) processor that supposedly supports PCIe3.0x4 lanes to a 2280 SSD. plus also has a dedicated e-key pcie slot for a wifi card. Plus 2.5gig LAN. You pay extra for the privileges of course, but it would also be a good option depending on what all you need it to do.
I have the non-B variant. Same cpu, just no wifi. Really powerful actually. Blows a raspberry out of the water in cpu and gpu performance. Good memory options. And the NVME M.2 slot is a fucking godsend. Being able to run 512gb or even 1tb of full fat flash storage that won’t fall over after a week of log writing like most SD cards turns it into a legitimate homelab server with a lot of flexibility
Runs super hot though, aftermarket cooling and a fan is an absolute must if you’re gonna run it near full load for any amount of time. And ofc it’s pretty expensive, pushing into Intel NUC territory. Can’t best the form factor and power consumption though, if you can deal with the relatively poor os/software support and ARM architecture.
It’s a little more than posturing, India and China have been at odds for a while. They’re frequent competitors for resources on the open market, which China has a better position in. China has also antagonized India over their borders in the Himalayas in Kashmir, as well as encroached on Nepal’s borders (which India views as a necessary buffer state and an in-kind extension of Indian territory).
Modi’s for sure been causing a lot of anti-democratic ruckus domestically, but his anti-China stance is pretty valid.
Slow burn to death might not be so slow. Good riddance.
