Chinese nuclear reactors built in China are completed faster than in other countries, and they probably [1] cost less. But it's not clear that Chinese nuclear reactors built in Western countries would be especially affordable. Consider this recently signed deal to build China's Hualong One reactor in Argentina:

https://www.neimagazine.com/news/newsargentina-optimistic-ab...

It is supposed to take 8 years to build and cost $8 billion for 1090 net megawatts (1170 gross megawatts) [2]. That's far better than Western AP1000 and EPR projects currently under construction, if it meets its targets. But it's far worse than the planned costs that Western AP1000 and EPR projects had at project start.

Or consider the relative pace of Chinese nuclear and renewable additions in China. China connected a record 8374 megawatts of nuclear power to its grid in 2018 [3]. (In 2021 it connected 2321 megawatts). At a 95% capacity factor, that's about 70 terawatt hours of electricity generated per year. In 2021, China added a record 54880 megawatts of solar power [4]. At a conservative 15% capacity factor, that much solar capacity will generate about 72 terawatt hours of electricity per year. It also added over 47000 megawatts of wind capacity in 2021 [5] which can be expected to yield more than 82 terawatt hours annually at a conservative capacity factor of 20%.

In terms of added electrical output, Chinese renewable projects are outpacing Chinese nuclear projects despite the much lower capacity factors for renewables. I suspect that's because they are much cheaper to build. There may come a saturation point where adding more renewables no longer does anything to displace fossil fuel consumption, because additional supply is all curtailed due to mismatched supply/demand timing, but curtailment can go pretty high (more than 50%) before nuclear yields more marginal decarbonization per dollar of investment.

[1] It's difficult to determine the ground level truth of Chinese project economics. The government is more heavily involved in the economy, press freedom is limited, and language barriers make it hard for people who only read English to keep abreast of what appears in Chinese publications. I am acutely aware that the only reports I read coming out of China are things that somebody else wanted translated into English.

It will be Interesting to see how the kids who get irreversible surgery will grow up. Will some number of them grow to resent the influence their parents and teacher?

There have been numerous documented cases of transition regret. I wonder what the impact will be when that number is multiplied 10x or 100x.
> If you are going to let your kid talk to strangers on the internet, teach them safety like avoiding sexualized content.

Problem with this is kids are sneaky, curious and liars.
I think it's just an aspect of competition, and people's ego. In most competitive games, human psychology is just as important as any other aspect, and trash talk has been around since forever in order to tilt a player.

I don't personally view this as a negative.

It's the team-based games where kids are constantly yelling or berating their teammates for missteps that are far more annoying and negative.
In my 2nd job out of college I found myself taking a position with a startup to shepherd along a neglected project while the core team worked furiously to deliver their signature project. That project team was led by what can only be described as a sociopathic madman. He'd throw items around in his office and scream profane insults whenever a problem came up (QA finding bugs app crash/bug/missed graphics/etc.). He'd dress-down he responsible party with no pity in front of others. The team feared him - but nobody quit because there was a significant bonus promised to them on delivery.

The management team tolerated his exploits as they desperately needed the project delivered as there were substantial performance bonuses for early delivery, and significant penalties for late delivery. The team was cajoled into a "death-march" in the last few weeks with unlimited drinks/snacks and free meals for staying late and classical psychological manipulation for attempting to leave "early" (anything before a 12hr day). (I can still hear him saying to people "we're a team - how can you let your teammates down, you p** of sh*t")

In the end, the project was delivered on-time, but as the company had bet on an early delivery and so, had spared no expense in throwing resources towards that project, there were no bonuses. Instead, the team's extraordinary work was rewarded with layoffs...

I'm optimistic that that in today's environment (assuming you work in a free and open society) such behavior is no longer widely tolerated. First, I think that society has evolved and with the emphasis on work/life balance, people will refrain from subjecting themselves to a boss like the one described above. With high attrition, companies will remove people like that from oversight positions. Also, companies themselves can face consequences if they don't address such behavior immediately. Nothing like a surreptitiously recorded video or audio recording appearing on the internet to bring a public shaming.
I do wonder how "needing things" has changed personal finance. This is obviously alot more complicated then I'm going to describe here, but there's the common trope of "don't eat that Avacado toast and buy an iphone and maybe you could afford a house." And this is obviously laughable given the rise in home prices, but at the same time, I think it gets at a certain idea that there are so many more expenses today than you had in our grandparents day.

Also, I think it's more vogue in modern times to charge for things that used to be free. My friends just went camping and it was $40 a night. What was that cost in the 1920's and how has that changed as a percentage of income over time.
Most compelling comment in this sub-thread.
$2 spent does not make you a "whale". I don't have any great links off-hand, but in-depth analysis has been done on this topic with other cash-shop games and the reality is that the majority of revenue comes from a very small proportion of the user base. It's beyond Pareto. I have also been a "whale" in my past playing a Korean cash-shop MMO, where I spent somewhere in the neighborhood of $10k over 2 years, compared to the average person spending roughly what a subscription to WoW would cost ($15/mo, or $360 over the same time period). "Whales" spend an order of magnitude or more than the average user in the user base.

In Roblox it's obvious from this article how this plays out. People betting $10k USD per pull in a virtual casino, or laundering money, or giving hundreds of USD to children for sexual acts, are spending massively more than parents enabling their children to spend $5/mo on in-game items. Because from the perspective of the companies the revenue is recognized when the in-game currency is purchased, not when it is utilized. E.g. if you buy $10k USD worth of Robux, it doesn't matter to them whether you buy the equivalent amount of in-game items or not, they've already gotten your money and turned over to you the virtual/in-tangible item you paid for.

Mobile games in particular manipulate people who are susceptible to this paradigm, which is one reason I personally don't play these games, because I know that I am susceptible to this form of manipulation. I have online gaming friends that I am aware of who spent tens of thousands of dollars on mobile games, the gacha game genre (Genshin Impact for example) is particularly onerous here. Roblox is taking this mechanism, applying it to children, and using it to empower adults to commercialize the sexual exploitation of those children in a secondary and tertiary market built on their platform. This is pretty blatant.
I do not agree.

Actual 'nuclear' (Uranium fission based) is a proved environmental risk:

- Chernobyl, Fukushima Daiichi (INES level 7) are not some sort of small environmental incidents

- Kyshtym, First Chalk River, Sellafield (1957), Three Mile Island, Goiânia (INES level 6 & 5), and maybe the Tomsk-7 explosion (not rated) where comparably smaller but the environmental impact was not small

- we still do not know what to do with nuclear waste in the long term... But we do know than this waste is not a 'green' crap

- fortunately nuclear waste is not drooped anymore in the ocean... but only since 1993! The quantity rooting under the sea is estimated around 200,000 tons (this also include waste from medical usage). Everybody look elsewhere and cross finger on this.

- (we could also add 8 or 9 nuclear submarines rooting under the sea, and an unknown number of lost wea
pons, but i agree than this not from civil reactors)

- it is no secret than environmental researchers who study marines currents, already use "small leaks" from know origin since a long time. The quantity may not have environmental impact, but the leaks are big enough to be used in scientific studies. See for example https://hal-normandie-univ.archives-ouvertes.fr/hal-02433310... (and many more for the English channel)

That said, Nuclear power could be environmental friendly. Thorium based reactor are promising. They are certainly not 'green' but, far less problematic. Also Fusion reactors could be the perfect 'green energy' if solved.

But, Uranium fission based reactors, are useful: you could use them to start your nuclear bombs collection... And this is one of the historical reason why the Green parties and Greenpeace are against them. With reasons, because actual nuclear plants, do come from military origins (most are based from submarines reactors), and in nuclear power countries the separations between 'nuclear civil' and 'nuclear military' was never a real thing. The other big reason is the historical 'democratic' way all this nuclear plants where build: simply rain local authorities with money, and put anti-nuclear militants in prisons.

Personally, my main problem with the uranium reactors is than it's a dead-end technology. It's true than it do not product greenhouse-effect gas and create a lot of energy, but it's like taking a very big loan instead on working on more secure and less risky nuclear energy. Or investing in more renewable energy, or in less energy consumption, or in non-battery powered electric cars...

Saying than it's 'green' is just green-washing from the actual nuclear lobby.
But the python bindings are great and useful to many, so Python gets to be added to the list.
A somewhat contrarian view. I've always viewed Roblox suspiciously. However, at the same time, I believe it is fairly harmless as long as your child remains in the confines of Roblox and isn't lured into other social networks like Instagram, Snapchat or similar which I think can be effectively monitored and restricted.

I think that the big advantage of Roblox is that just like it is a decent game sandbox, it is also a good real life sandbox where children can safely learn about the online world, the risks and how to mitigate them (good passwords, never share your passwords, don't tell random strangers private information like your name, etc.). Assuming, I can prevent them from getting lured into other social networks, the worst that can happen is that they lose their Roblox account when they make an inevitable mistake. In my view, it's better that they learn these lessons in Roblox, at an early age, rather than later with social accounts or, worse, financial accounts.

Roblox' problems can be a useful educational tool.
I prefer my own mess over someone else’s mess :)
Well, maybe, but most nuclear reactor designs are at least 50 years out of date, and a lot of progress was made between 1970 and 2000.
I usually say: if things tend to change together, then they should be closer together.

This is also why using layers as your primary method of organization is usually a bad decision. You're taking things that change together and strewing them about in different top level directories.
I don't understand this.

Let's do a thought experiment: say the speed limit in State X is 60mph. In State Y is it is 70mph.

If you went to State Y and drove at 70mph there, will the police in State X arrest you when you come back because you went over 60mph, even though the claimed "offence" was in a different jurisdiction where it was totally legal?

This whole thing about people having abortions where it is 100% legal (or even just - heaven forbid - tracking menstrual cycles) and then getting into trouble for it in places where abortion is not legal seems really weird. I can't believe it is being discussed in the US - this is like something out of Afghanistan.

and living in Vegas, I've really given serious thought to building some sort of NN to help with gambling in general and specifically the picking of horses (or perhaps even baseball outcomes).

I can't help but think that buried in all the race data their are correlations that are impossible to figure with standard statistical methods but can be sussed out using NNs. Of course I am vaguely aware that many people are already using NNs to predict race outcomes, but I am purposely trying to keep that info at arms length as I don't really want to be negatively influenced existing attitudes.

However, if someone does happen to know of a good NN/horseracing blog that has a positive outlook and is making money, I would be interested in such a site.

Anyway, this type of easy-to-use NN could be exactly what I'm looking for with getting started on this project, and once again, I would be interested in hearing about the pros and cons of using such a lightweight easy-to-use NN for my explorations.
Putting few tons of radioactive material on top of dozens of tons of highly explosive rocket fuel... what could possibly go wrong?
I agree. What do these apps collect that prove that a user received an abortion? Even location data pinning a user at a clinic doesn't prove anything.

I have a question though- Do abortion clinics in other states have to comply with subpoenas?
This is a serious thing that any app maker needs to plan for. Your work can be repurposed as surveillance, and the conditions for that can change in surprising ways.

Apple does a pretty good job of taking this into account, minus their iCloud "back door," but they're almost the only big company that does this, and obviously a big part of that is a strategic opposition to both Google and Facebook. I could be wrong, but it seems to me like, after Apple, the only companies who even think about this are relatively small, privacy-focused companies like ProtonMail.
Well, putting aside that CSAM isn't active at all at the moment, you're correct it didn't apply to iMessage (sending an image in iMessage couldn't trigger it unless the user saved the image), and that iCloud Photo Library needed to be on.
Yeah, and banner blindness is about more than just things that look like ads. The top and side bars of webpages traditionally contain information about the website as a whole, and are not relevant to the specific page you are viewing. You look there to navigate away from the page you are on, but ignore them when digesting the content you came to read. This would be true even if ads hadn't ruined our expectations, and has analogs in other media. In a book, you don't expect users to read the header/footer (page number, chapter, etc) each time they turn a page. Those are there to navigate through the book more quickly, but are ignored once you get to where you want.
Not sure who 'we' in this situation is, but there are certainly a good portion of lower and middle class people feeling the economic pain through rising cost of every day items. My outlook is that we will eventually see this result in a drop in discretionary spending and that is probably when we might expect to see wide spread layoffs or upticks in unemployment.

I played Roblox with my kids for one day before we had to nix it. Even with chat disabled, most “experiences” are barely even games.

We play real games now, or occasionally Minecraft mods. The frozen Minecraft adventure mod is quite fun
I think a js framework doesn’t make sense because all people I know dealing with dnns using python as base language. I’m also working on something very similar and I think my stack is a lot better because I used pyodide + webassembly + webgpu . So far, I managed to implement a very small grad based dnn framework with couple of ops. (like matmul, etc.)

One of the limitations is that webassembly vm has 4gb address space. This could be a problem during loading/unloading from/to gpu.
you are a either a blithering moron, or acting in bad faith

few people are saying "the gestapo will literally be called to your house the second you miss a period in a red state"

but rather, that this data can and will be used as collaborating evidence in a criminal trial.

a state prosecuting an abortion will have to prove the person is actually pregnant, and there is zero reason to believe they wouldn't use this data as one more tool in their arsenal building a rock solid case. it's not as if people undergoing illegal abortions are going to have good records that can be looked up otherwise

you are a bad person

I think looking at who is relevant in the AR/VR space currently is like asking who was relevant "pocket computer" market back in the mid-90s.

There are some products in the market, some people use them, but functionality is limited, and there isn't a killer app or use case yet.

Many people are saying resolution, or other tech is what is holding AR/VR back, and that may be partially true, but PalmPilot unlocked the early handheld computer market by restricting use to what was possible at the time, and having a few killer features for a small subset of users.

Blackberry then extended on that, and we thought that was the market. Decent quality email on the go was such a huge draw they owned the market.

Microsoft was making some inroads with PocketPC, but Crackberry really owned the market, and thought they'd own it forever.

Then came iPhone and Android, fullscreen devices, touch keyboards, real internet on the go. It wasn't even the apps at first, but the ability to use the web, and not a half-assed version.

So, is MagicLeap irrelevant? I think they probably are, not because of technology or hype, but because they didn't find the killer app that will make the market valuable.

I've worked with a CEO of a 3rd generation family business who would denigrate employees at any opportunity, thought he was a genius who solely built the company, "no raises in the budget" after frivolous $x,xxx,xxx company purchases statements and other unsavory behavior.

It could have been a great opportunity for my own goals, combining both marketing and development responsibilities, but it wasn't worth the constant second guessing and putdowns (e.g. you only increased revenue from -10% to +30% in 3 months, why not 50% type comments without jest), so I just found something else.

It is hard to spot in interviews, because the only people you are allowed to speak to are those who are complicit. Once you start working and people open up, you hear all types of red flags. Glassdoor used to be good for gleaning insights, but now it is probably curated for companies willing to pay.
those are not "clinics" and certainly don't call themselves that otherwise they would be in huge troubles.
At the very least it's a signal to hurriedly look for a new job, if not resign on the spot.
Economics is too broad. For example Land and Real Estate is zero-sum, as is strictly Debt/Financial/Monetary exchange.

Some things, as with blue skies research, really do create more wealth as in overall some technological advancements make making some things cheaper, or available.

Creating debt to print capital now for making X cheaper to produce is generally good as that zero-sum is offset by the wealth/wellness created by that capital in the future (a company producing cheaper components for example).

Meta exists in a zero-sum market, as advertisers fight for the same limited resource: attention (an individual can view as much advertisement in 24H).
It clearly was NOT a museum or gallery. It was a place like this:

Does that seems a museum? That's the problem with Venice (stupid) tourists, they think it's a open air museum, it's not, it still is a city with people living there.

I may see the point of a different alternative than current NodeJS ecosystem. However, QuickJS only focuses on the JS runtime while misses all the system interfaces provided by V8.

Said that, I really like QuickJS too and it's portability as JS engine.
