DanTheManPR··on Smaller reactors bring nuclear power closer to fulfilling its promise
This is an important point: in a lot of ways, SMRs are a strictly worse than 1000MW plant. The potential financial benefits come from all the other factors you mentioned. I would rather have a "worse" nuclear power plant that actually gets built.
DanTheManPR··on Smaller reactors bring nuclear power closer to fulfilling its promise
We're looking specifically at new power plant builds. The majority of that is in Asia, with China and India being the bulk of it. But there is a lot of Asia outside of those two, and in particular Southeast Asia has a lot of potential. There is a lot of long distance transmission line connectivity already, and more planned, but you still want to product power close to where it's used so as to avoid losses in transmission. And the finances for a smaller country are just more straightforward if you're not spending multiple billions of dollars on one giant plant.

The next big market is actually replacement plants in the USA and Europe. Electricity generation may have peaked there, but much of the generating capacity is decades old and needs replacement. There are a lot of smaller facilities that are not gigawatt-scale that need to shut down, and it's easier to plug that gap with SMRs.

South and Central America are small markets, but they won't be ignored. There is a lot of complexity here with the inter-national hydro projects and broken up grids, so I'm sure some countries will look into SMRs.

Africa unfortunately just doesn't factor in except as a long-term possibility for growth. It's only 3% of electricity generation now, and its share will probably fall as Asia electrifies.

This is all worst-case scenario where SMRs are less financially competitive than current gigawatt-scale designs. If SMRs do actually succeed in being cheap assembly-line reactors, then all bets are off and the industry will experience explosive growth.

Nuclear regulation could genuinely do with a lot of reforms that would streamline the process without appreciably impacting safety. Everyone would benefit. And that's the huge problem with the administration's breaking of trust and naked corruption: we as a lay people, what should we think if they come out with a bunch of proposals eliminate a bunch of commercial licensing requirement and lowering radiation safety standards? Is that because the old rules are genuinely archaic and not serving their purpose... or because Trump's family and donors are personally financially invested in the very companies mentioned in this article.
DanTheManPR··on Smaller reactors bring nuclear power closer to fulfilling its promise
A lot of people are betting serious money that they will cheaper, more flexible, faster to build, and safer. Including me - I'm working in the industry, and I think they might very well be future backbone of energy production.

But there's a real possibility when all this shakes out that SMR's only advantage will be their flexibility. And that might be enough. A major issue with gigawatt scale nuclear is that it's frankly too big for most markets. Only very large electric markets can can easily digest a new always-on 1000 megawatts of electricity, and you need to be building multiple plants at a time for this all to be economical. That's why the nuclear power rollout of the 60s through 80s worked, and why China and to a lesser extent India's nuclear industry is thriving presently.

With an SMRs smaller scale, there are just way more available projects where nuclear is feasible, and so a more consistent workload can keep everyone employed and subcontractor's backlogs filled. The flexibility in scaling lets you reclaim the benefits of having an experienced workforce and that knows how to build nuclear power plants, something we lost in the west when we stopped building them.

DanTheManPR··on Worst-case glacial lake flood scenarios in a transboundary Himalayan basin 2022
They were in a sense correct, because the aerosol cooling they were worried about did in fact (and continues to) have a fairly significant cooling effect... one that is offsetting the rapid warming that CO2 is causing presently.
DanTheManPR··on The AI bubble is popping; we just don't know it yet
I would rather be market-corrected out of a job for a few weeks or months than have this inflate into an economy-wrecking bubble that derails my career and life for years. I'm worried that we're at that state already...
DanTheManPR··on Ian's Secure Shoelace Knot
It's just a good knot. The only downside is that it is very slightly more complex than a regular shoelace knot (you pass-through both loops instead of just one). But otherwise, it's only upsides: completely secure, unties exactly as easily and quickly as a regular shoelace knot, and it even lays more horizontally than a regular shoelace knot.
DanTheManPR··on Solar and batteries can power the world
This is basically correct in the sense that we cannot simply just force everyone in, say, Minnesota to install electric baseboard heating, rooftop solar, and a battery pack, and then expect them to stay warm. There are periods of extended extreme cold and low solar flux where you would simply not be able to warm everyone's house - that's just physics.

But there are a lot of extra things you can do as an intermediate steps to dramatically close the gap. The main ones are:

1. Homes can be renovated to improve insulation 2. Cold weather heat pumps can handle most mild winter conditions efficiently 3. Electricity doesn't all have to be locally generated - it can be transmitted from other parts of the country. 4. You can keep using fossil fuel peaker plants, and still have incredible reduced overall emissions

DanTheManPR··on The R47: A new physical RPN calculator
It's probably not a necessity - I'm sure I could adapt to just using my smartphone if I put the time into learning some of the math apps. I still use my ti-89 for everyday calculations. It's a handy device; more portable than a laptop, and better UI than a smartphone. I don't deny myself from using a tool I like.
DanTheManPR··on US High school students' scores fall in reading and math
I'm much younger than you, but I had the experience of having a difficult-to-find-info-on-the-internet subject for a high school paper, and the opporunity to researching the subject at a well stocked library. There was a lot of friction to the process that I wasn't used to, but the serendipity aspect was absolutely revelatory. There is something fundamentally unfiltered about walking past shelves of books with titles on subjects you never even knew existed.
DanTheManPR··on China completes green belt around Taklamakan Desert
Is Chinese high speed rail infrastructure really substandard or lacking maintenance as you claim?
DanTheManPR··on We are shutting down Ondsel
I've had multiples of my students get into legal trouble over the years from using these. Just understand that almost all of these professional level software packages phone home even after being cracked, so you basically have to airgap your computer if you use them. It's a major reason why I steer them towards open source CAD packages, and towards the pro level CAD packages with usable free hobby licensing.
DanTheManPR··on How the iPhone 16's electrically-released adhesive works
The current collector also takes up relatively more volume, on top of the packaging (the wall thickness would be the same, and it's not a trivial part of the volume of small cell batteries).
DanTheManPR··on Show HN: Hestus – AI Copilot for CAD
I've been a Mechanical Engineer for a similar length of time, using Solidworks and Creo, and I concur. I've released many thousands of parts over the course of my career, and I don't think of the modeling itself as a major time sink (provided you have some decent training, and are using a thoughtful approach and not fighting the software). If the AI copilot could actually do all the modeling based on prompts, that would be pretty interesting, especially if it could create a feature try that I could tweak.

Automatic drafting is something that I think might be a good target for doing some AI research on. Your prompt exists in the form of the solid model, and it's feature tree and parameters. The output is the lay out views and annotations. It's okay if the output isn't perfect, as I would expect to be reviewing it and doing some tweaks.

Helping with all of the ERP processes involved with releasing and maintaining engineering documentation would be a HUGE time saver. If I could ask a copilot program to start a change request, and give it some basic descriptions of what I'm changing, it would be massively helpful if it could start pulling relevant files, and auto-filling the right requests/forms/whatever to do that process.

DanTheManPR··on An FDA approved device offers a new treatment for tinnitus
I've always wondered that too. In very quiet rooms I hear quite intense ringing. I have distinct memories as a young child of wanting a fan turned on in my bedroom at night because of the sound of silence was ringing. It seems like what people describe as tinnitus, but... I don't seem to have any of the hearing loss that is always described as causing tinnitus. I can quite clearly high pitched noises such as CRT monitors and ultrasonic mosquito repellent. I don't have a history of working with loud equipment or going to concerts, and in any case that doesn't explain why I would hear it in childhood. It all doesn't quite correspond with with a lot of the causes and symptoms I hear described.
DanTheManPR··on Most people think the U.S. crime rate is rising. They're wrong
Here's an anecdote: I haven't been the victim of any type of crime for the last 15 years, whereas I had multiple break-ins and near violent encounters in the 00s and 90s. My neighborhood and city (I live in Northeast Minneapolis) feels dramatically safer than it did when I was younger. My relatives in the burbs think it's some sort of crime infested hellhole. I'm inclined to think that a actually, crime IS dropping and that people who think that it isn't watching and reading a lot of media that is filling their heads with nonsense.
DanTheManPR··on WinUAE 5.1.0
...what is this? The page has no About section or any explanation of what WinUAE is.
DanTheManPR··on 280M e-bikes and mopeds are cutting demand for oil far more than electric cars
It's a class 1, so it will assist up to 20mph. I typically cruise at around 15mph on my own (I'm in a similar weight class as a rider). For getting around my town, trips are not much longer than my car.
DanTheManPR··on New Windows updates cause UNSUPPORTED_PROCESSOR blue screens
What keeps me trapped using Windows on my main home workstation is simply that a lot of the professional software I use is Windows-only, and always will be.

Fortunately, the advancements in Proton and better cross-platform support for a lot of software has let me use Linux on my gaming computer and notebook. There are a few games which I can't play, but honestly there's so many options available that I don't miss them much. I don't think I'll ever completely eliminate Windows from my life, I think around 2021 was The Year Of Linux On The Desktop for me.

DanTheManPR··on The Precipitation Problem
Humans have been putting a lot conscious effort into modifying our world for our own benefit. We've converted a huge amount of our land area into farmland and cities for our own use, which has had a lot of upsides for our current lifestyle. But rampant dumping of pollutants into the atmosphere hasn't usually had a lot of upsides, whether it be lead, or CFCs, or CO2. Climate change is not a directed endeavor with a goal, and so it's not surprising that it causes a lot of havoc.
DanTheManPR··on The Pentagon’s $52k trash can
I'm guessing that what's happening here is that Boeing could be making more money doing something other than building trash cans, and so is sending an absurdly exorbitant quote to their customer to communicate "stop buying this".
DanTheManPR··on McDonald's just dropped a brand new Game Boy game
I just tried the rom out on my flashcart, and it boots and plays on a real gameboy.
DanTheManPR··on CEO: Raspberry Pi stock to hit 1M units monthly, starting in July
This is the killer aspect of the RPi, that there are tons of well supported drop-in software solutions for it. Other boards can be made to work, but the RPi will just work.

I was surprised to see so much equipment right next to the launch vehicle in the video. Would all that have gotten damaged during the launch?
DanTheManPR··on Imgur Updates TOS, Banning NSFW Content
This is going to be incredibly damaging to forums, in the same way that Photobucket's deletions were. Old forum posts are becoming a ghost town of broken image links.
DanTheManPR··on Why don’t more people live close to friends?
One way to do it is through hobby groups which meet IRL. You can make friends in the hobby-space there, and then gradually start inviting them to things that are not related to the hobby (becoming more of a true friend).
DanTheManPR··on I wish GPT4 had never happened
I am begging you people to read Karl Marx's Capital Vol 1, Ch 15: Machinery and Modern Industry

Do you fear washing machines because they eliminated the requirement for doing the laundry by hand? If not, then why is automation in the workplace different? We fear AI and other forms of automation in the workplace because we have no ownership or control over our economic destiny in that space.

DanTheManPR··on If we lose the Internet Archive, we’re screwed
>Dude. We're not talking about losing secret ancient knowledge. We're talking about losing pictures of cats.

But we're literally talking about book lending, and preserving the old knowledge of the early internet. However lofty and pretensions the analogy may seem, comparing it to the burning of the library of Alexandria actually does seem like a better analogy than "we're just losing pictures of cats"
