So why are these undersea cables so expensive?

Lets do a little Math... A cable that moves 4GW of electricity 450 km is say +-1 million volts and 2000 amps.

Assuming we want no more than 3% losses in the cable at full load, then each conductor needs to be 40mm diameter aluminium, at a total material cost of $3.6M

To insulate a 1 million volt cable, we need 100mm of PVC - total cost $60M.

And we'll obviously need a few mm of steel + more PVC on the outside for protection from the environment.

And now add in the manufacturing cost, and the cost to get it into place...
‘My AI Is Sexually Harassing Me’: Replika Users Say the Chatbot Is Way Too Horny
Show HN: Podcast on timelines, implications & responses to AGI
Like all of you here on HN, I love building & understanding technology. Several years ago, I read about the possibility & potential implications of artificial general intelligence (AGI) and it was arguably the most transformative thing I'd ever read about a piece of technology.

I believe AGI is closer than most think - probably in our lifetimes.

That means we're likely to enter the most exciting but also most disruptive period in human history. Cutting edge models like ChatGPT & DALL-E have convinced me the time to pay attention is now.

I want to ensure this future is positive & beneficial for our world. That's why I've started a podcast, The AGI Show (www.theagishow.com) to interview AI experts & understand the timelines, pathways, & implications of AGI, and to share those learnings with everyone as I go.

I have a huge amount of respect for some of the incredible minds that frequent HN and would love your perspectives on the podcast and the future of AGI. Please check it out and let me know what you think, so we can build an incredible, positive future together .
I agree with your comment, however please don't make new accounts just to respond to a single post or comment, judging by your username.
On the other hand, all kinds of technology have been regulated to minimize adverse effects. The trouble with software is that it is evolving faster than regulators can keep track of, and it is very hard to police even if regulated.
Heat pumps can't be more efficient than the theoretical Carnot heat engine running in reverse, whose efficiency is T_outside / delta_T. In this case it's (273-28)K/98K = 2.5.

I guess being 2x as efficient (cheap) as electric resistive heating isn't super-terrible, but it's not great either.

Compare this to a favorable groundwater heat pump configuration with good radiators and insulation where the 'outside' (groundwater) is maybe 10°C and the target temp 30°C (close to room temp): (273+10)K/20K = ~14.
Interestingly, religious families are above 2, but not quite to the 2.5 required to counteract people leaving the faith. Orthodox religious are above 2.5, so the future will be quite religious with ‘nones’ becoming more of a minority…

How about since they saw it coming to start investing in the transition to be ahead of the curve?

What baffles me is that these people knew and presumably had children or grandchildren, presumably breathed the same air and had the same houses in areas prone to wildfires, etc. and yet they didn’t take actions that would have been in their own interests other than financial.
Yes NZ is baffling. NZ is a place which could easily be 100% renewable with very little investment. There is plenty of wind, sun and the large hydro power station could serve as backup/storage. However I see dramatically less windfarms and solar installations than in a place like Germany which has much less sun and wind.
This list was nice to learn about some apps I wasn't yet aware of. One thing the author mentioned as a "con" a couple of times is "No option for automatic deletion of messages". It might be worth noting that no app can provide automatic deletion of messages. Yes there are some apps that have messages disappear after a time but there is nothing stopping those messages from being saved by the other party before that time. If not a data export then a screenshot, and if not a screenshot then a camera pointed at the screen. If the message is to be consumed by a human then it can be recorded.
In that case, you would have the second email address on file and it would be connected to the customer's overall record in the CRM.
The really old buildings obviously had no ventilation other than simply being not-very-sealed. Only a couple of generations ago there were still houses with single glass windows, there weren’t any moisture barrier film in the building shell, doors weren’t well sealed and so on.

The second gen with forced exhaust emulates the old self-draft by forced exhaust ventilation and that exhaust air has to be replaced by air that enters somewhere and since the air is evacuated from kitchen/baths it’s let in through all other rooms. Yes that air can be cold/dry and it’s also uneconomic if it’s -20C so these vents are adjustable so you can close them somewhat when needed.
Heat exchanged air forces both from and to the building is of course an improvement over the from-only, but the ductwork required is much more complex so it’s mostly done in new builds. The great thing about forced exhaust only is if it’s combined with a heat pump that reclaims the heat so it’s not wasted.

As far as I know the rule of Thumb regardless of system is that all the air in the house should be replaced every two hours using only the base flow i.e excluding the kitchen fan. So air quality is ensured for both systems as they shift the same volume of air, but comfort and economics is better with the more expensive system (no freezing fresh air entering).

Maybe not: "The Transport Secretary announced on 19 October 2022 that the Transport Bill which would have set up GBR would not go ahead in the current parliamentary session."
If oil companies have been campaigning specifically to deceive customers about the potential harms those customers may cause, then that should be what they are "held responsible" for. Trying to make them responsible for harms others caused using their products is rather orthogonal to that, and doesn't bolster arguments criticizing them.

Tangentially, while some vehicles presumably have worse mileage than a comparably-sized vehicle from the 1980s, fuel efficiency has significantly increased since 2005 (after a small decrease from 1985-2005) while supporting continuously increasing power and weight [0]:

In the two decades prior to 2004, technology innovation and market trends generally resulted in increased vehicle power and weight (due to increasing vehicle size and content) while average new vehicle fuel economy steadily decreased and CO2 emissions correspondingly increased. Since model year 2004, the combination of technology innovation and market trends have resulted in average new vehicle fuel economy increasing 32%, horsepower increasing 20%, and weight increasing 4%.

I'd prefer the single line magic one.

Exactly because now.. what used to be a menial computation required to get from A to B, has become a Thing, its existence has been justified not just by the declaration of a named function, but it has been blessed by the allocation of holy inodes and filesystem entries and versioning control entries, and oh god no, now it's been promoted to "actually important piece of infrastructure" by the greasy hand of a unit test. It has become a goal in and of itself.. What used to be a worthless piece of "I have Id's I need user objects"-getting-it-to-work has ascended and become immortal. Hours of work will now replace minutes, it adds drag to the entire system, not just in code size and bulk, but in developer mindshare, it exists and must therefore be considered and payed some amount of respect.

It is painless to delete a single line of "doing stuff" when refactoring something..
But alas, in the end, the function call is deleted, but it lives on, either unreferenced or shows its ugly face in other parts of the code, now mutilated and mutated to support "that thing that sounds like what it did but not quite"..

No, flamethrowers alight! Kill it with fire! Let it never be born.

And I'm actually very much in favor of DRY. But that mainly is about repetition, not about spawning as much "structure for the sake of structure" as possible.
But "Wolfram" comes from German, as it was described in the 16th century already. The isolation of pure tungsten then was done by Spanish scientists.

>they correctly identified only 68% of the generated abstracts and 86% of the genuine abstracts.

I think you and I are basically in alignment... what this tells me is that 14% of real abstracts are so bad that other human beings call their BS. Meanwhile, this AI stuff is kinda working 32% of the time in generating legitimately interesting ideas.

So at that point - yeah, that sounds about right. The 32% is still so low that it shows AI is not anywhere near maturity, whereas 14% of human-generated is crap.

And, yeah - a short blurb like an abstract seems to be exactly the kind of text that ChatGPT is conditioned to do well generating. As others below note - once a human starts reading the rest, the alarm bells trigger.

I like how regulations got rid of lead paint, got rid of LA’s pea soup smog, stopped rivers from being so polluted they’d catch fire, and brought back the American eagle. Just a few examples.

a reactionary “all regulation bad” view is too simplistic and doesn’t make for good discourses.

but what do I know, I must be biased because I’m not a fan of asbestos.
Since we have the whole video in advance (we can look forward in time) and we can also measure the response function of the pixels, it would be possible to preprocess the whole video to make it look even better (less ghosting).
Stories about how difficult it is to get into the field and actually having difficulty getting into the field are two very different things. 2 out of the 3 employers I've worked for had explicitly discriminatory policies favoring women. And they weren't subtle, we straight up reserved slots for women despite this being blatantly illegal.

In reality, the proportion of women in STEM directly matches the proportion of women in STEM majors, which directly matches proportion of women who say they're interested in STEM.

My partner runs a medium sized ecommerce store on Shopify and her priority is having a system that is simple and stress-free.

And whilst she appreciates all of the Shopify Apps they are secondary to the fundamental process of taking, processing and shipping orders.

I dunno about that. I remember how microsoft were back in the IE days. They could have used comments for really bad stuff.
>> That way, it's not a "me vs them" dynamic.

Yes - definitely helps in scenarios where an engineer starts talking directly to a product manager/non technical management and starts accepting feature requests and cranks them out with little thought about the long term supportability of their code by the rest of the team (and perhaps builds in a little extra job security intentionally or unintentionally via code obfuscation) and is reward by looking like a 10x engineer to the non-technical side of the company.

Rows of red next to their name will organically slow the engineer down and encourages less code that feels like "job security through obfuscation/abstraction" and long term will guide them toward soliciting more feedback from the team early on in the design cycle to ensure their code is grok-able enough to get green marks. Then they can truly by identified as a legit 10x'er.
First thing I do when I get a new laptop is to plaster the lid with stickers. If I see somebody at a coffee shop or conference or whatever with a laptop with a plain lid, I tend to instinctively think of them as kinda boring (until proven otherwise).
I had to think a bit about the "wet radiator" and then realized we're talking about potentially older houses that circulate hot water to metal radiators in the house.

In that case, yea, it would be a {something} to water heat pump to heat up the water, and then circulate that water through the house.

It would be curious if there were installations that did the other way too. In theory, you could also circulate cold water in the summer. The problem would have been "how do you make the water cold?" and in many older cases, that would be impractical. Though... that could lead to condensation on the radiators in the summer which could have downstream effects (condensation drips water on the floor).
This equipment would be installed outside, the difference being to position it near, or coupled to, the compression loop of the heat pump. When the pump is running, it draws from the battery, which will need to dissipate heat through its operation. Why not capture that heat and redirect it where desired.

In summer, you could decouple it and use standard separate heat dissipation mechanisms.
The current HVDC link has had a lot of upgrades from the original 600MW to 1200MW now, and there are proposals to upgrade it further, but not nearly to the scale you suggest, as there just isn't the need for such levels of transmission.

Unless there were plans for major new hydro schemes in the South Island there's no particular reason not to just build new generation in the North. There is ample wind and geothermal in the North Island.

This would all change if the Tiwai Pt aluminium smelter were to close as that would leave a huge amount of generation that would need to go north to be used.
Extra capacity and/or reduction in demand.
In neoclassical models growth is just a function of the productivity of capital and the amount of saved capital. It is that simple and that is why especially Austrian economists insist that saving is the source of wealth or something.

But what Keynes realized is that the bottleneck isn't actually on the saving side, people actually save more than enough to grow the economy very quickly but they don't deploy those savings and hence they don't result in the expected growth. So insisting on austerity just adds a bigger pile of savings onto an already over supplied capital market while at the same time decimating consumer demand for the capital seeking investment opportunities. People don't invest because the economic outlook is bad for the next year or the year after. Faced with uncertainty they would rather just keep liquid money in their bank accounts and wait for the economy to recover but how is the economy supposed to recover if everyone is pessimistic about the future?

BTW where I can find a good open source multi-party computation (MPC) library. There are good resources at [1] but it seems most or all of these libraries are outdates, unmaintained, and/or unaudited.

The point was that even with a sustainable fertility rate of 2.1, the daycare system would only need to employ a few percent of the total workforce.
I don't know what you're talking about. People believe things you disagree with. That's not a conspiracy; it's literally just the human condition.

I think one of the most important elements is buried - electricity pricing is uniform across the entire UK. That seems nuts to me, and incentivizes building in locations that are less useful - it's likely cheaper to build in Scotland, higher production from more wind, you get paid more (for expected yield plus curtailment apparently), and you have less wear on the equipment when you adjust to lower output.
It would be more interesting if this paper studied low-level molecular pathology of ageing, i.e. protein crosslinks, advanced glycation end-products, etc. These pathologies are going to remain even after the supposed fix of epigenetic decay.
Are you suggesting a UK approved build of curl?

No not at all. People that want ways around the restrictions will find it. Parental controls are to inhibit actual children as determined by the parent from stumbling across adult content and Twitter. Not to be confused with the legal definition of children, I am referring to small kids that might accidentally happen across ads for a porn site or user generated junk on their parents cell phone, tablet or laptop. It must be up to the parents to decide when their little ones are psychologically armed to face the only-partially-censored-web we have today.

Legislation should require all the mainstream web clients that small children might happen upon have parental controls and honestly I think this mostly already exists. They likely just need some tweaks to the user experience and look for the RTA header. Browsers used to have this. Shimming that code back in place should take a few minutes.

Teens that are looking for porn will find ways around restrictions. If real security and authentication were forced for every web company then teens would just create an underground network. Lets call it The Darker Web. The Ultraviolet Web? The Sticky and Confused Web? I honestly can't think of a catchy name that teens would use.
i understand how you can come to that conclusion, but it was really oversized for what it was cooling.

I would urge you to avoid using loaded words like "smart". It's not that they're "too smart for their own good," it's that their priorities aren't aligned with the business's or customers' priorities. For the person who dislikes white space, they're optimizing for reading the code themselves, but there are likely to be many more people besides them who look at the code. They need to understand that the priority should be making it readable for others rather than themselves, for example.
Instead of fighting against that feature, why not instead ask permission from the user?, just like the APIs of location and notifications do

This is not enough. We need to mainstream using fake data whenever possible.
One reason is because ruby has a large standard library. Also people just pick what they know - there are more js devs than ruby devs. Also neither ruby nor node are a good choice for a cli, so it is kind of a moo point.

Seems like factoring the location is the easiest solution. If energy were much cheaper in Scotland, some factories would move there, more people would move there as well and you would not need to transport so much energy across the country.

But I guess there are more things to consider than the energy in that decision.
I have worked with/adjacent to several film archiving projects and yes, there's a fire extinguisher in the room but no, it's not like people work in fear. At all.
You're not totally wrong, but people who work on archiving film in real life are much more concerned about vinegar syndrome and decay (not to mention copyright). Most old film is just rotten and stinks like vinegar. It crumbles in your hands.
It's so cool how far we've come with exoplanet discovery in such a short time! The first one was only in 1992 and it's so neat seeing us go from only picking up giants to being able to detect smaller and smaller planets. Now to get chemistry from a rocky planet?! Awesome.

I wonder if having AI models available would make it significantly easier to identify material created by that model. Seems it would be easier, but it would still be a big problem. Nets can be trained to identify ai vs not ai on a given model. And that's without needing access to the model weights, just training examples. But when there are N potential models...
