Hello,

Your example paper has omitted non-English characters in the names of anyone who gets cited. Look especially at citation [5], where a lot of the authors have European characters in their names which get omitted.

There is also possibly a missing × or ⋅ in "1.81 10^5" on page 3.
SMRs are 'fine' for smaller grids. For example, the province of New Brunswick has a CANDU 6 reactor, which is 1x660MW of capacity:

* https://en.wikipedia.org/wiki/Point_Lepreau_Nuclear_Generati...

CANDUs are pretty flexible in that there's a lot of maintenance (including refuelling) that can be done while it is running, but there's still some stuff that needs to be done when the system is powered down, which means taking down a large source of power for the grid.

If there were 2-3x300MW reactors, when there could be rotating maintenance without much impact to the grid.

You say Troy was considered a myth as if it were an absolute, it wasn’t, it was debated among scholars.

Fact is German archaeologist Heinrich Schliemann was one of those learned people that didn’t think it was a myth, and in fact did locate and excavated a city matching the descriptions.

That’s how science works, things generally tend not to exist until there is proof or record of their existence, science doesn’t default to things existing until record of their non-existence emerges.

Thank god for that, qualcomm in a market owner position would be bad for everyone.

But is there a real demand for this? AMD is killing it on the desktop and laptop and while battery life can be improved I'm not sure an architecture change is the best way to do that.

And while I've owned laptops with really long battery life, I have honestly never more than 5hrs away from a power outlet. I'm not against progress, but this one is not a priority for me.
For decades now politicians and others have brought up the correlation of higher education degrees with incomes and then making the claim that if everyone got a degree then everyone would get a high paying job.

But that isn't how it works. There are a finite number of these high paying jobs and they tended to be assigned to those with higher education degrees. But if the market is flooded with people with these degrees, it doesn't make the number of high paying jobs go up. It fact it may even make some of them pay less. But mostly they will just fill up and a bunch of people with degrees are left over. The more degreed people, the less likely they'll be to get one of the high paying jobs.

Another similar fallacy I also see and hate is the one about lower mortgage rates or easier financing making housing more affordable. It does the opposite! Because more people will be enabled to buy, they will bid on the finite number of houses and prices go up until they are unaffordable again.

the limited feedback from https://news.ycombinator.com/user?id=siumauricio here and the stonewall response to the, very serious, license issue discussion on github is very concerning.

this has every look of a potentially talented developer that seriously misunderstands the legalities and role of open-source. there's probably a way to do what they intend, but this ain't it. and you don't make "open-source" but say "mine! mine! you can't change it/use it".

does this violate any github policy? certainly the apache foundation should have a word.

Yes. Also, there really aren't any such niche areas save some military naval applications. Even there, most ships in the US navy are not nuclear, because burning liquid hydrocarbons is cheaper.
It's expensive because people are scared, and to alleviate that fear, regulation is put in place.

Some of those fears are founded, but some are not. But overall, the regulation required is what drives the cost up.
NuScale's SMR is ~77MW - which is a medium sized data center.

AFAIK, that's typical consumption for data centers being built today.
At least back in the day (might be fixed now) with type covariant mutable arrays.

That is array of cat is a subtype of array of animal. And a function Foo taking an array of animals and appending a dog is legal. Because array of cat is a subtype of array of animal, you can pass an array of cats to foo and append a dog. I believe this causes a runtime type exception, in a type-checked language without using any dangerous casts.

I kind of assume modern java has addressed this somehow, I would love to hear how.
Depends how you define "good". I consider this concurrent GC algorithm [1] to be "good" and it can be implemented in a few hundred lines of C. I'm going to disagree with the article and say GC's aren't "scary" but they do require thorough testing.

Machine Learning for Econometrics
These are the lecture notes for the course Machine Learning for Econometrics (High-Dimensional Econometrics, previously) taught in the third year of ENSAE Paris and the second year of the Master in Economics of Institut Polytechnique de Paris.

They cover recent applications of high-dimensional statistics and machine learning to econometrics, including variable selection, inference with high-dimensional nuisance parameters in different settings, heterogeneity, networks and analysis of text data.

The focus will be on policy evaluation problems. Recent advances in causal inference such as the synthetic controls method will be reviewed.
If you mean using Incus on Flatcar, there is a PR for adding Incus as systemd-sysext extension.

Flatcar inside Incus is a bit more difficult: for Flatcar being a container one can import https://stable.release.flatcar-linux.net/amd64-usr/current/f... and for it being a VM I don't know if the regular image works. A major hurdle is that one has to tweak the way VMs/containers are configured because normally Ubuntu's cloud-init is used but in Flatcar only coreos-cloudinit or Ignition is supported and there are differences in the way the user-data has to be set up and the contents as well. But in the end Incus would be one more "cloud" platform to support and one could make the Incus integration as nice as with other platforms where Flatcar runs on (OpenStack, VMware, etc.).
What do you mean? The lower unit costs is exactly the point of SMRs.

> Solar+battery gets you there today, is getting cheaper every day, and there’s almost zero project risk.

Debatable. In Ontario nuclear costs 10¢/kWh while wind costs 15¢ and solar 50¢ (Table 2):

* https://www.oeb.ca/sites/default/files/rpp-price-report-2022...

And when wind goes to zero at night, then (natural/methane) gas generators are often spun up (generating carbon emissions).

Meanwhile the refurbishments of Ontario's nuclear plants are on-budget, and often ahead of schedule:

Where does the data come from for this? The Gaia satellite database?
It’s expensive because environmentalists put in too many barriers to building nuclear power plants because they’re scared (in addition to being innumerate). If we had started building out nuclear power in the 1960s the same as the French, we would have much more runway today to address climate change.
It’s not happy feel good shit – China is installing as many renewables as they possibly can, while building more nuclear than anyone else, and it’s still not enough electricity for their growing economy. It illustrates the constraints because they built all of those panels themselves, and they’re the best at making them.

A lot of the coal capacity they are building, though, will be used for peaking, just like a lot of our natural gas plants.
I started including backwards walking in my workout routine last year. It has definitely helped my posture.

Another interesting benefit has been the extra “workout” that my brain gets. It’s quite a challenge to walk backwards, and even more so through varied terrain, such as on mountain trails. Quite the mental/physical challenge, especially the first few times.
Thanks, that's a nice quote.

With regard to the debate, I think it's good not to engage in too much black-and-white thinking. Science itself is a pretty muddy affair, and we still haven't grown beyond simplistic null hypothesis significance testing (NHST), even decades after its problematic implications became clear.

That's why it's so important to look at the macro implications: I.e. how does this shift costs? As another comment nicely put it, LLMs are empowering good science, but they are potentially empowering bad science at an order of magnitude more.

I just use an overlayfs of /usr pointing to a folder on my SD card. Then I just use their arch.. Every 3 to 6 months I pop out the SD card, update their stuff, then pacman install a few dozen packages main packages (and the quite a few more dependencies) that I need. I put it in a script for convenience.

The only issue I've had is their static snapshot of arch has some inconsistent dependencies from time to time that need manual handling, and occasionally they are missing a cert change so you either choose to trust the package from their server anyway and install it with a cert skip, or do without.

Aside from that, everything seems to work well, and if there were any problems, well I can always just reboot with the SD card removed.

I was worried about how /etc might interact with their stuff, but seems fine so far, and I assume they left it writeable for a reason.
I do do backups just in case.

In much of Western Canada, energy use is highest at night in deepest winter when there is no appreciable wind, meaning that the grid is completely reliant on gas-fired power. If we want to reduce gas-fired capacity, we need another source of on-demand power. Meaning either nuclear or a robust storage solution. There seems to be more enthusiasm for the latter, but there’s no buzz about any viable solutions on the horizon.
It describes the problem in a nicer way tbh. I haven't yet read the preprint but the video is neat.
How does removing their code help anyone? It barely makes the tineist bit of difference to Open AI, if any that's detectable. They aren't the only one's helping with that kind of code.

pirate787 is enumerating what they see as the problems, not what they view as the solution.
CANDU are a great design; the calandria is a nice adaptation to the capabilities of Canadian maufacturing, and it is impressive to see the lines of reactors at Bruce, Pickering and Darlington. It is also a widely exported design, with China constructing reactors on a 4 year timeline.
Granted a single large reactor would dominate the grid, but I presume there is grid connectivity to adjacent provinces. An alternative would be a large energy user (aluminium, heavy water production) to soak up the excess power and turn down when one unit comes offline.
Some Russians were so annoyed about alien theories so they recorded a video how they drill the stone themselves using only ancient instruments.

The cost over time generally tends to weigh heavily on the initial budget. Small reactors don't replace large ones for large needs, even if multiple are built (this hasn't even happened yet!).

What small ones can do is afford either government/public/private energy sources in localized areas. Infrastructure was built upon technology stacked on top of previous; dirt to stone, stone to asphalt, and on; etc.

The same is inherent with nuclear. It is easy to tie in to the existing grid, but the grids are extremely out of date for the growth of populations in general.

A large mix of SMR's could absolutely fuel energy needs in both the short and long term as technology continues to improve. The cost is a metric of current economics/interest. That's the problem right now - perspective states it's unaffordable because we've pivoted it that way.
I’d love to automate a push mower to mow for me. I think I will build my own RTK base for that following these instructions. https://simeononsecurity.com/guides/budget-diy-gps-gnss-base...

I want a push mower because the available robomowers all have tiny razor blades instead of a actual mower blade and a limited range. My lawn isn’t gigantic but it’s not perfectly smooth or even and I dread paying that price for something that either won’t work or frequently breaks the blades.

As far as lidar and wifi positioning - that could give you sub-cm, but I would go away from positioning to create a mower that knows the difference between a road and a lawn, a flower and a weed, and your lawn and your neighbors. A dream would be just giving the mower the same ‘mow the lawn’ command you would give a teenager and it just working. With the way things are now, these mowers have to be driven around the perimeter and no-go zones created manually. I saw one guy whose lawn was more of a field plotting out the entire mowing track in software with his automated push mower. It’s better in the software then going out to the field to drive it like an RC car, but it’s still far from some5ing like ‘full self mowing’
Excellent! I’m glad my input was interesting.

txtai has some demos of automated semantic graph building that might be relevant.

I noticed you didn’t really use any existing agent frameworks, which I find very understandable as their value added can be questionable over DIY approaches. However txtai might fit better with your overall technology style and philosophy.

Has your team studied latest CoT, OPA, or research into Cognitive architectures?
Sweet mama speed. Although from what I understand it is more legacy speed cause you're losing all your time to fetching the memory anyway. But when processors were slower it was a meaningful amount.
Yeah, since the ‘90s, and still does in this thread. They’re usually going around insisting you ignore that your lying eyes can consistently spot Java programs by their incredible memory bloat and poor performance, and that actually it has great performance (in some synthetic benchmarks).

I do think they’ve gained a little credibility now that we’ve inexplicably decided Electron is a serious platform and not an April Fool’s joke.
There’s also the cost of rewriting (yes, from assembler) all the existing code. And don’t forget QA.
Ontario gives hope to the nuclear dreams. Being able to deliver projects on-budget gives decision-makers cause to believe project plans.
Lets hope that another 4-pack of CANDU reactors will be built, to further the soverign industry.
Part of the problem in building conventional nuclear reactors is that an $11Bn project like the conventional build mentioned in the article is of such a scale that it’s inevitable that something will go wrong that causes the budget to explode. The sales pitch for small reactors is they’re not $11Bn projects, so there’s a possibility they could actually be completed on time and somewhat near budget.

The author is also clearly anti-nuclear - that’s not to say they’re not right, but they’re motivated.

Too bad all of those totally don't matter. What you're saying here comes down to doing what management wants. And management, above all else, DOES NOT WANT THE STATUS-QUO UPSET. The chairs in management are to be divided according to endless politicking and 5000 meetings for every line in the org chart, the only thing that matters. If any effort is actually successful beyond what was agreed beforehand ... that would undo the "work" of thousands, maybe tens of thousands of management meetings.

In other work drafting design documents, doing interviews, improving existing codebases, mentoring junior ICs (to do the same) ... it's not a design document to create a new successful product on the internet. It's a design document discussing whether component #1823871 of Google maps should be monitored by a Python, C++, Java or Go program, and whether it this monitoring server gets configured using json, yml, chubby, files with strings, protobuf, python (configuration in code, python to configure flags, python to configure startup files, python to change build files, or python read by the program upon startup), Go, Java or Go. Don't forget: 8 page minimum, and you can't have less than 40 reviewers.

This document is then followed by a manager from outside your org deciding that the whole monitoring is being shipped to India, and 3 months later you check on borg ... and surprise! There ISN'T anything monitoring it, as far as you can tell. Your manager assures you your work was not for nothing, but your design document curiously has never been accessed, and everybody you ask (btw: you're quickly told you're not supposed to do that) says management forbade them from looking at your design document.

Later you learn that there isn't a single team in India that actually has access to your document (if you're working long enough at Google and actually know how to check that, which used to be 99%, but now ... perhaps 20%).

A year later, the product takes down all of Google maps, your team's lack of monitoring gets blamed for the outage ... but 10 minutes after you go to your manager with this the postmortem, suddenly, gives you "access denied". Then, you get scheduled for a support checkin where the person doing the support checkin has no idea what it's about.

Of course, what it's really about is that your forced one of the managers in your org to explain to higher ups how your concern is being addressed while still meeting budget constraints ... Which could have upset the status quo (recognizable by "Moderate impact" on your GRAD review) or actually upset the status quo ("Not Enough Impact" on your review). Congratulations!
Existing nuclear, in Canada, is basically the best case scenario for nuclear Vs the worst case scenario for solar and batteries.
