This reactor indeed has lower power density than a PWR, but not by a factor of 12. I compared it with NuScale's reactor, which is a PWR SMR. Details about both can be found in [1]. The HTR-PM reactor pressure vessel has a volume of about 640 m3, and yields 105 MWe, while NuScale has a volume of 101 m3 and yields 77 MWe. The power densities come to be 6.1 m3/MWe vs 1.3 m3/Mwe, and the ratio is 4.7x.

Still, this is a good price to pay for getting a meltdown-proof reactor.

> Pebbles themselves are also problematic, they tend to swell, crack, and they can't be reprocessed using the current technologies.

It is simply not true that pebbles tend to swell and crack. Quite the opposite happens: fuel elements in the current generation PWRs tend to swell, crack and burst. This happens because some fission products and decay products are gasses, such as xenon, kripton, radon. They build up in time and create internal pressure. The same happens inside the fuel kernels in the pebbles used in this reactor, but those kernels are specially built to withstand much higher internal pressures.

Here's a relevant quote from [2]:

> As the pressure vessel size is reduced, the more efficient spherical geometry can be adopted, and the required wall thickness drops dramatically to the point that a 35 μm SiC layer can indefinitely contain gas pressures in excess of 100 MPa. This compares to the main reactor steel pressure vessel which may go as high as 20MPa or the Zircalloy cladding which can have pressures up to 10s of MPa in limited conditions – temperatures far below what the ceramic pressure vessel tolerate

As for the reprocessing part, I think you are jumping the gun. There is no reprocessing done in the US, at all, for any type of fuel. Even where reprocessing happens, as in France, the benefit is quite reduced. One can extract some plutonium and unburned uranium, but in the end that will allow you to extract maybe 10-20% more energy from the original amount of natural uranium. It will not make you extract one hundred, or 10 times, or even just twice as much energy. Reprocessing is simply not a game changer. It is not clear at all if it makes economic sense to build the highly complex facilities that do reprocessing, for the limited benefit.

It’s been talked about here before, but fundamentally it’s when the advertising guys won the power struggle over the search engine guys. Previously, advertising was a means to fund cool technology (and also get filthy rich).

Now it’s just a way to make the number perpetually go up, sucking every last drop of value out of the system.

Plus the complete lack of vision or strategy from Google’s senior leadership.
I may be daft but it seems like a great idea. Same weight and everything. In France you get a decent subsidy if you convert your ICE to EV.
It doesn’t seem to me like the GP commented before looking at the article. I think it’s justified to clarify a title that’s prone to be misleading. That’s different from editorializing, which is inserting one’s own opinion or agenda in the title.

What's your opinion on sycl?

I think my reading of your comment is: that's just wrong. And I tend to agree. The current STEM and FAANG activity is second order work in the main. I wouldn't hold AI work up as a paragon, myself. It's diverting from progress across a field.

I have hopes of a resurgence of operations research and linear optimisation as goods in themselves: we could be plotting more nuanced courses in dark waters of competing pressure. Decision systems support across many fields would remove subjective, politicised pressures.
This is a funny comment because that's almost exactly what I have a degree in. The point here isn't the engine though, even though those are also a separate beast, but rather that all of these vehicles are packed to the brim with a bunch of chips with internet access and you have no idea what's really running on them. With electric cars we're seeing even more of this than with ICEs.
Labeling midi controllers as theater props is an insane take. Midi controllers are essentially programmable instruments.
If the people who made it know much about telecoms, then no, the will not work. When your mobile device connects to the Internet, the connection tunnels through the mobile network to a gateway specified by the "APN" (access point name). This is usually set up automatically these days, but you can dig the setting out of your phone. That's for an Internet connection - however a company can pay for a "private APN". This is still a gateway, but they control what it connects to. This is often done for machine to machine connections, e.g. for utility smart meters - so a SIM for a gas meter will not be provisioned for the normal Internet APN, and if you were able to get that SIM out (difficult as they are not usually in card format) you would not be able to connect to the Internet. Typically the equipment company will negotiate a cheaper data price than for Internet access, since the data usage will be low and predictable.

Now it could be that the people who built this tracking device are too small scale to negotiate a deal, or just don't know this, but my guess is that (a) the SIM is not in a physical format which can be removed and fitted in a different device; and (b) it is connected to a private APN which is not connected to the Internet.

BTW, if you look up the Wikipedia article, bear in mind that it is a bit inaccurate - for instance it refers to an APN as being a gateway to the Internet, which is not always true. I'll correct it some time.
I don't know. I suspect that a good percentage of the roofing was probably done by carpenters at that time.

AI is a societal shift that will take place over the next 20, 30, and 40 years, much like what happened with personal computing. This is a time horizon that impacts investments right now. Professions that existed for thousands of years will cease to exist. That is an unbelievably big change.
I really hope my post didn't come off as if I was trying to make it sound like this was a new idea. Regardless, this is good information, because it counters the posts of the form "great, now that you made this, you're going to make it harder."
Giant Freakin' Robot was an aggregation site. Its "content" is links to other web pages with blithering about them. Google seems to recognize aggregation sites now, and down-ranks them. Google itself is an aggregation site, and there's no reason for it to pass traffic to other aggregation sites.

I think the combination of driverless trains and automated platform screen doors is the gold-standard for new metro-like systems. The new REM in Montréal is able to have very high frequencies with much lower cost, so transit users should be able to get more transit for the same cost and the municipality isn't worried about the burden of high operating costs for the next century. The platform screen doors are great too, anyone who's taken the Metro enough has had to wait for hours because someone has fallen onto or committed suicide on the track, which feels like such a sad problem to have when the solution exists.
You haven’t. That’s cool though, I can understand your frustration.

I am also frustrated by the dramatic increase in scope of the federal government versus the Enumerated Powers in the Constitution, but even given that background, I think this very likely falls within the power to regulate interstate commerce.
Fair enough, I never really took those claims seriously but will concede that many still seem to be in that headspace even now.
Feels like they were exploiting an artifice and always derived more than e.g. 75% of their declared income from a single source. As an outsider I believe the NL have some amazing obligations on employers above a certain size regarding social policy mandates and so the employer side may well have been complicit in this, to avoid social imposts for larger enterprises.

(Bodies I work with in Amsterdam have mandated workers councils, bicycle levies, social employment obligations, education and training requirements which scale to size)

You could do all that, or just require PINs for credit purchases. They're not near as good as passwords, but PINs are still much, much better than nothing.
It would at least be significantly less of a problem, if items purchased didn’t have such negative externalities as part of their production.

I don’t see why a culture significantly less prone to desiring items that aren’t actually all that beneficial, would be incompatible with capitalism?
Twitter absolutely did sell reach, if not by that name. And they currently sell reach boosts via premium subscriptions.
These are good suggestions, but maybe it’s worth noting that one of the solutions offered in the article is not equivalent:

I'm surprised they dismissed the OSSC [1] so easily. It's not "just" for game consoles and arcade equipment. It has a VGA port on it for a reason!

Admittedly I haven't used it for anything nearly as "esoteric" as some of the gear Cameron has I'd be surprised if he encountered any issues. Though being open source I'd suspect if he did he could simply fix them himself in the OSSC's firmware if needed!

An OSSC will happily upscale any weird resolution/framerate you feed it to something modern HDMI devices can "understand". I use an "EVGA XR1 Lite" [2] to take the OSSC's HDMI output and feed it in over UVC to my laptop with USB-C. Works flawlessly and is dirt cheap

If Cameron wants a bit more of an "all-in-one" solution, myself and other retro tech youtubers like Tech Tangents, RetroRGB and others use old Datapath RGB E1S cards [3]. This thing is basically just a DVI port glued to an FPGA. It doesn't care about "resolution" or "refresh rate" it just DMA's raw pixel data right into RAM and lets what ever application you point at it decipher it. Personally I think they're pretty awful (comparatively) to the above option. The driver is a binary blob (so it probably won't work on Cameron's POWER machine) and it crashes a lot both under Windows and Linux. Though it seems more agreeable under Windows for changing resolution and other settings via OBS

>Of course Russia is a corrupt dictatorship with a deliberate policy of sowing lies and chaos, and China is on the same road. But look at your (our) own governments, they are far from the angels you seem to believe them to be.

"Both sides equally bad" is a Russian talking point/propaganda. You fell for it, congrats.

But at least my country has all indoor plumbing... like at some point one thing is better over the other. For quality of life I would rather be in the EU rather than the USA sure.

You cannot put western governments to a perfect standard and russia/china as inperfect. China is trying the same sneaky shit being classed as Third World country for climate and economy to get grants.

87 BMW here. I believe my servo is controlling the throttle cable itself. When the cruise control commands the vehicle to accelerate, the pedal physically moves.

It's not my daily driver, but I would absolutely love to one day get another one as a project car - one that's not in such good condition that I'd feel bad removing the engine - and drop an electric motor in it. That likely _would_ become my daily driver. The car's incredibly well made, and a joy to drive.
This is one of the most interesting things about AI to me.

As a lifelong computer nerd I've always dreamed of having a computer friend who knows all about my life and who I can bounce ideas off, it's a core sci-fi trope. But I tried these new LLMs everyone was so hype about and... nah, they all feel like I'm wasting my time. Anything I want to actually know I can look up myself faster than negotiating with these things to try guess what they want me to tell them so they will actually do what I wanted. And as far as just being a nice personality to spend my time with goes, they all come across to me as awkward or pretentious or fussy, and not what I want my computer friend to sound like. If I need to spend 20 minutes trying to "train" my computer friend how to sound vaguely like a real person, it's a fail, sorry. It feels like trying to socialize on Reddit or Discord, you waste a bunch of time going back and forth with strangers who are trying to be funny or clever but never actually say anything meaningful. Which is why I don't use those sites either.

But then I have real life friends who have mentioned they talk to these chatbots all the time, almost like a therapist, and they ask them questions about their lives. Obviously they don't take the advice as seriously as they might coming from a professional, but they still consider it a valuable interaction. To them, having this kind of stilted interaction with a hokey-sounding AI is worth something. And I don't get what they are seeing that I am missing. Perhaps my standards are too high? Or perhaps they just have a greater tolerance for wasting time?

Anyway, when surveys ask me if I've used AI, I always say yes. The worst surveys then do not ask a follow-up question of "did you think it was actually useful/compelling/fun", but of course they don't because the whole point of them is to build hype to sell the gimmick to another company who will shoehorn it into whatever.
Cross amplification occurs when a submarine branching unit (SBU) slips erbium-doped fiber amplifiers (EDFAs) at landing points, between isolators and a combiners, that excite erbium ions, maintaining them in L1 - L2 - L3 states configured to their relative wavelengths. Unlike coaxial amplification, which alters voltage in a continuous modification of electrical current, either prior to an RG-6 or RG-59 on spans managed by the ISP. Depending on where it's stored, coaxial amplification will require anywhere from 12-24 volts.
So who's exploiting this now? Exploits were known back in 2014.
