Uranium reactors are for the most part very safe, and I personally think we should consider building more of them. The problem with them is when something goes wrong, it can go very very wrong contaminating a huge area. Now granted more modern reactor designs make that sort of issue much less likely, but the worst case scenario of a uranium reactor, no matter how unlikely, is still a lot worse than the worst case scenario of a thorium reactor.
For anyone not familiar with thorium…
Thorium is a great nuclear fuel. Much much safer than the uranium we currently use, because the reaction works best only within a narrow temperature band. Unlike uranium which can run away, a thorium reactor would become less efficient as it overheats possibly preventing a huge problem. That means the fuel must be melted into liquid to achieve the right temperature. That also provides a safety mechanism, you simply put a melt plug in the bottom of the reactor so if the reactor overheats the plug melts and all the fuel pours out into some safe containment system. This makes a Chernobyl / Fukushima style meltdown essentially impossible.
There are other benefits to this. The molten fuel can contain other elements as well, meaning a thorium reactor can actually consume nuclear waste from a uranium reactor as part of its fuel mix. The resulting waste from a thorium reactor is radioactive for dozens or hundreds of years not tens of thousands of years so you don’t need a giant Yucca Mountain style disposal site.
And thorium is easy to find. Currently it is an undesirable waste product of mining other things, we have enough of it in waste piles to run our whole civilization for like 100 years. And there’s plenty more to dig up.
There are challenges though. The molten uranium is usually contained in a molten salt solution, which is corrosive. This creates issues for pipes, pumps, valves, etc. The fuel also needs frequent reprocessing, meaning a truly viable thorium plant would most likely have a fuel processing facility as part of the plant.
The problems however are not unsolvable, Even with current technology. We actually had some research reactors running on thorium in the mid-1900s but uranium got the official endorsement, perhaps because you can’t use a thorium reactor to build bombs. So we basically abandoned the technology.
China has been heavily investing in thorium for a while. This appears to be one of the results of that investment. Now this is a tiny baby reactor, basically a lab toy, a proof of concept. Don’t expect this to power anybody’s house. The point is though, it works. You have a 2 megawatt working reactor today, next you build a 20 megawatt demonstrator, then you start building out 200 megawatt units to attach to the power grid.
Obviously I have no crystal ball. But if this technology works, this is the start of something very big. I am sure China will continue developing this tech full throttle. If they make it work at scale, China becomes the first country in the world that essentially has unlimited energy. And then the rest of the world is buying their thorium reactors from China.
Nope. There are a great many species of mosquitoes. The only one that bites humans is the female of one specific species. Those little fuckers have killed more humans than any other cause of death, second only to being killed by other humans.
There has been some fairly extensive studies and it has been conclusion that even if we extincted that specific species, it would not cause major ecological changes.
Currently the best way we have of eradicating them large scale is by genetically modifying and releasing huge numbers of them that are non-fertile. If this is able to specifically target that species and not kill others, it could be a more effective answer.
DMs are exactly what you expect, like private email. Every service has some form of this.
Reddit chat is real time, designed for shorter messages and real-time communication.
The other difference is that everybody uses Reddit DMs and nobody uses Reddit chat. I have my chat turned off as do most others that I talk to.
So this is yet again another example of Reddit management not reading the room and forcing the use of a system people generally don’t want.
Sad but true. And they are taking some good stuff with them.
Squeeze box back in the day was the biggest competitor to Sonos. All open source. Logitech bought them, then just shut it down for no apparent reason. Same thing happened with Harmony. Best user programmable remote on the market, Logitech buys them, then shuts them down for no apparent reason.
I wish someone would scrape together a few million bucks or whatever Logitech would want to sell both brands, buy them, and resurrect them.
Not at all. In fact Creality seems quite open for a Chinese company. There’s literally an option on the touch screen menu to enable root access. That gives you full SSH access to everything on the board, no hacks or jailbreaks needed.
The firmware is Klipper based, mostly open but there’s a few binary bits. There are some open source firmware forks but the one thing they haven’t got running yet is the bed pressure sensor so you need to add a separate sensor for leveling and z axis zeroing.
However the stock firmware works great and with some open source scripts you can add whatever you want to it like fluidd/mainsail.
My k1 Max has lived its entire life on a private network segment, only internet access it gets is NTP to set the clock. It’s perfectly fine. I have never registered with Creality cloud nor has the machine tried to force me too. I use orca slicer and feed it the g code and it works great.
Yes it can.
The fob has no idea what it has access to, in most systems it just has a serial number. When you tap it on the reader, the reader scans its serial number. The system has a list of which key numbers are allowed to open which doors at which times, if your key matches it opens the door. These almost always have some kind of log of which key opened which door when. Whether the building management knows how to access that is anyone’s guess.
If he loves in a building with fobs there’s probably cameras also.
So if he’s worried about after the fact investigation into his movements, he should live somewhere else.
They aren’t even trying to come up with believable lies any more, right?
Yeah I’m wondering that too.
I looked at the thread on Reddit and I can’t find one single user who says this is a good idea.
I used to. I turned it off. There’s an option somewhere to completely turn off Reddit chat.
Yeah this is why I don’t use Plex.
At one point I installed it on my NAS. It goes through the setup, and then says I need to make a cloud account. Wtf? I am running locally hosted software on locally hosted hardware to access locally hosted files. Why do I need any cloud for this?
I don’t. I uninstalled it.
Yeah exactly. I tried to set it up once, installed it on a NAS box, and it starts talking about me making a cloud account. Why do I need a cloud account to log into my own hardware on my own network?
I do not want the cloud
I do not need the cloud
I will say it very loud
No cloud, no cloud, no cloud.
But apparently it’s set up so the only way to log into your own locally hosted software on your own locally hosted hardware is with an external cloud account.
To that I said no thank you and uninstalled it.
Problem starts earlier in life. I know someone who is a teacher in lower school. Ask the kids to make a presentation and literally in 90 seconds you will have a PowerPoint with 15 slides full of pictures and embedded video. Ask them to write one slide of text and they’ll struggle to put three sentences together.
Reason is pretty simple, a lot of the parents never read to their kids. They grew up on iPads. Video is the medium they are accustomed to. And so they struggle with written information.
This is disappointing for Rossman. I like his content a lot and he’s on the right page, but I think he’s big enough that he needs to start adopting some journalistic standards. For example, if he reads that some company is doing something stupid, at least bothered to call them and ask for a comment before he drags them through the mud on his channel.
Exactly. I would extend that and the article’s premise to say, tech isn’t innately good or bad, it is just a tool that can be applied in good or bad ways. For example at his cafe, a QR code ordering system could have been optional for those who prefer it, and could be easily implemented without collecting any personal data. And that could actually be a positive thing for those who want to reorder without getting up or who have social anxiety. But by forcing all customers into this confusing and privacy invading system, the tech becomes a bad thing.
The villain of that story is not tech. The villains are the online ordering company that decided to make a data grab, and the cafe owner who decided to buy tech so he wouldn’t have to pay servers.
How many times did he shoot himself?
I mean there is a pattern to these things.
If Putin doesn’t like you, you shoot yourself and then jump out of a building.
If the Clintons don’t like you, you shoot yourself twice in the back of the head before driving your car off a cliff.
If you have dirt on powerful people, you hang yourself in prison.
That practice was halted and now the vehicle video is under MUCH stricter control with an option to not share any of it at all.
Given the choice, I’d rather have some Tesla employee joking about what I park next to than Tesla Inc selling my driving data to insurance companies like most other automakers do…
That was from years ago.
Tesla used to sell cars rated by pack capacity. For example the ‘P85D’ was the performance model, 85 kWh pack, dual motor.
There was also a 40 kWh (cheaper) and 60 kWh version.
After a while they stopped building 40 kWh packs and just software-locked the 60 kWh pack to only have 40 kWh of usable capacity. I think for a while they offered an upgrade where you could pay to unlock the extra capacity.
I don’t think they’ve done that in some time. I know when I bought my car (model y long range) they didn’t even advertise the pack capacity nor was any upgrade offered. The only paywall thing I’ve seen with Tesla is FSD and they’re pretty transparent about that. I don’t think they’re awful for paywalling it, because if they build the car without the FSD hardware it won’t have other safety systems like lane departure notification.
I’ve done it. I think it might have opened the charge port or something. What do you think happens?
Something to consider…
Elon may be going down a conservative rabbit hole these days, but this is the sort of thing Tesla would never ever ever do. And things like using the telematic system to sell your location and speed to insurance companies. Never happened on a Tesla. You may not like the guy, but the cars are fucking solid.
It’s a matter of implementation versus invention.
If I asked you to build a hundred story skyscraper, that would be difficult, but we already have all of the technical components. All the component problems are already solved- we know how to make high quality steel, we know how to design the frame of such a building, we know how to anchor it into the ground, etc. You just need to put those technologies together in a functional design.
If I asked you to build me a spacecraft that goes faster than light, you couldn’t, because that sort of propulsion system has never been built. And while we have theories on how one might build it, we don’t currently have the capability to build any of those theoretical drive systems even as test articles (mainly because they need things in space larger than we have the capability to launch or will have the capability to launch anytime soon).
But if I asked you to build a thorium reactor, all of the component problems have been solved. We have a lot of coatings that resist corrosion, and so making valves and pipes out of them (and more importantly, designing the system of valves and pipes) takes work but we know how to do it. We understand how to make and process thorium fuel, even if we don’t have much experience doing it.
As for your grid, I don’t want my grade either powered by text that isn’t safe reliable and productive, but the fact is we don’t have that right now. A lot of power still comes from coal and similar shitty sources. So I will absolutely take less shitty.
Yeah I use the word if a lot, but that has a level of probability associated with it. I can say if we figure out a way to generate power from magic pixie dust tomorrow our energy problems will be solved but there’s no probability of that. Here there is a technology that has been known to work since the 1900s, that we have built research reactors on, and that is now being actively developed. The “if” here has a high degree of probability.
