The article has Fig. 3: "SEM images of Fe–Mn–K catalyst" showing differences before and after use, but doesn't seem to explain how long you can use it, and whether it then becomes an unrecoverable waste product or what.

The trouble with news was the need for a server to store the entire feed. The network wasn't fast, so it had to be decentralized: every server storing everything, updates being sent over land-line connections. That was OK for text-based discussion groups. Then the binaries groups got to be the most popular, and hogged enormous amounts of disk space.

But I can imagine writing a new nntp server using the same front-end protocol, but using IPFS for storage and server-server transfers. Then it would only take a few servers in the world to redundantly pin all the content, while most servers would just fetch and cache locally the content that the clients are requesting. So you can use all the classic news readers. That way the whole experience would look just like it did in the 90's, rather than being a web-based facsimile, and yet the server storage requirements would be affordable enough for anybody to run one on any old Linux box.

Write it in Rust or Go, of course, so that it's compiled into one executable with few dependencies.

You can click around and see radiation history in various places around that date.

The closest site might be this one in Finland:

https://www.uradmonitor.com/to...

which isn't that close, but doesn't exhibit a spike either.

But way more ordinary Russians need to be buying and installing these at home so that a coverup of a radiation incident will never again be possible. (Or is there some other monitoring network that has better coverage?)

STM32F0 and SAMD21... so it's not cheap and can't be.

Is the connector standardized for CAN? Otherwise they could have picked one that's easy to install by crimping, like RJ11. We've already been there with the Dallas one-wire networks: either use RJ11 to have power, power ground, signal and signal ground, or RJ45 because those connectors are more readily available and some extra pins are there just in case. Or maybe use an audio connector, for convenience and robustness, although those are more trouble to make up your own cables.

But there are other standards for a reliable low-speed low-wire-count low-compute-power network. But differential signaling is a must, and higher voltages help to make it more robust too.

A worthwhile next step would be to get an open core design for one of these incorporated into a next-gen Risc-V based microcontroller. Then all the makers could get behind it, just to support the open-IP ecosystem.

Remember when RepRaps used RS485 between components? (e.g. https://reprap.org/wiki/Extrud...) And there have been smart stepper motors. I kindof thought that idea was going to take off, early on, but most seem to have decided it's cheaper to centralize the logic and the stepper drivers on one board. But that doesn't scale to larger machines. If CAN has an advantage over RS485 for that, it might make some sense; but I still think one micro ought to be enough to implement it; and if it's not, then CAN is probably the wrong choice.

Wireless is popular, but every device needs power so nothing can really be disconnected for the long term, unless it runs from solar power. (Batteries either have to be plugged in to recharge, or else they are environmentally unsustainable. Or both.) And there is the ongoing suspicion that RF exposure might cause health problems too. Whenever that risk finally hits the majority's radar, which technology is going to be in position to be the next contender? LiFi could be fairly easy I think.

I had an idea years ago to incorporate optical fiber into every power cable and every power outlet (simply standardize the position on the plug, relative to the other 3 prongs, assuming a choice of fiber technology such that precise alignment isn't necessary), so that when you plug anything in, you get networking at the same time. But that's a chicken-egg problem.

Alternatively, find a way to make one of the powerline networking standards cheaper. We can't get away from in-wall wiring to power stuff; so, one way or another, the network and the power wiring ought to be combined, IMO.

Reminds me of Mystery Science Theater 3000.

Maybe that explains it...

CONFIG_DOUBLE_STUF

cause you know more is always better...

nevermind, campaign is suspended now...

Please get this posted.

Either the pressure will be good for them, to prove all the alleged capabilities before the end of the campaign, or else (more likely) they do not deserve to be funded.

I can't even get qemu to emulate a raspberry pi faster than the pi itself on a Core i7 processor. I don't suppose going the other direction would work any better.

When I dreamed of having an intelligent computer a decade or two ago, I never dreamed that it could only be accomplished by sending queries to some big corporate-controlled cluster and getting responses back. I don't want to use Siri or Echo, because of this spying which is so far inherent to AI, and because Amazon and Google exist mainly to sell us stuff, to exploit us and get us to buy more of something. When open-source AI is capable of doing something useful, then I will run it on my own machine.

But can we ever expect an AI to get anything done without communicating? A lower standard: can we expect it to communicate to the extent necessary to get something done, but still respect our privacy? To have a positive answer requires an AI with ethics. It's probably more work for the AI to understand what is necessary to respect the user's privacy (like a good friend would do) than to answer the questions we ask of it.

So it's literally a burning platform.

I think it will blow over. But I'm bummed because I wanted to buy one; guess I'd better wait until they have solved it in production rather than by recalling or by just hoping for the best. OTOH it's not "open" enough is it... Sony is trying to get their stuff supported in mainline Linux, so is a Sony phone my best chance of both having "flagship" specs AND running a real convergence-oriented Linux OS on it in the future? It's just a matter of time until Ubuntu and Plasma Mobile will be able to move on from that libybris on top of Android hackery... I hope. I want modern Wayland, modern Qt, the ability to plug into a monitor, and total freedom with software.

I'm getting by with my original Note for now; there's still nothing much wrong with it, other than being slow, not lasting as long as I'd like every day, and needing the occasional reboot. I had to replace the board with the micro-USB connector once; it got too loose and wasn't making good enough contact to charge reliably.

Now if they had just made the new Note with a replaceable battery like my old one, that would make it much easier for anyone who already bought it and doesn't want it igniting in his pocket.

Why aren't the batteries standardized by now anyway? EU should have tried to make that happen, right after the micro-usb charging standard. They could keep growing in capacity, but keep using a few standard sizes. I don't care if the phone ends up a mm or two thicker because of that.

I happen to like using ZFS.

But fine, distributing drivers with binary blobs is OK, while this little license incompatibility between two open-source projects is a big deal. Whatever, dudes.

Seriously, 3 years of unfulfilled temptation? Such a vial wouldn't survive very long on the Mir.

But then, vodka doesn't benefit so much from aging.
