European Commission Joint Research Center Technical Reports: HVDC Submarine Power Cables
in the World

https://publications.jrc.ec.europa.eu/repository/bitstream/J...

According to table 1, losses for 800 kilovolt HVDC systems can be as low as 3.5% per 1000 km. That comes to 52.5% loss over 15,000 km. Losses should go lower at 1100 kilovolts (the highest voltage HVDC systems running today) but I can't find detailed loss numbers on those systems.

At 52.5% energy lost in transmission (47.5% retained), this is still considerably more efficient than making hydrogen via electrolysis, liquefying it for shipping, and then burning the hydrogen in the receiving country to generate electricity.

This particular plan is breathtakingly ambitious and would no doubt cost a fortune. It may appear more attainable when (if?) the similar but smaller Australia-Singapore Sun Cable project gets built:

That's ok unless you are running something virtual like kubernetes on top of the EC2 instance but want to ensure isolation between containers/pods.
> My theory is that taste is one quality that separates the academics from the business people. Academia doesn't necessitate a lot of taste. If you have it, great. If you don't have it, no big deal.

This might be true for academics in ancient Greek literature, but certainly isn't true for academics in CS nowadays. If you don't have good taste in research problems that are {important for downstream industry applications, scientifically interesting, tractable}, you won't get anything done, and you won't get published. If anything, the pressure for academics to develop good taste is stronger than for people designing product. You can have a product that provides just one utility that users desperately need and have terrible taste for all the other axes that make a product "good," and do just fine. Academic papers get judged (in peer review / traction after publication) purely against the taste and aesthetics of other people in your community.
Governments should stick to governence and stop doing stupid shit.
This summer I visited the remarkable Slanic mine in Romania [1]. No matter how much you prepare, it's still breathtaking when you get there. The chambers I visited were all about 50 meters tall. You could have football fields in there, bleachers included. I took pictures, but I just don't know how to share them; still, I found this one [2] that gives a sense of the scale.

Intel gets it and is adjusting to be a foundry that builds chips to application spec.

For me cloud computing is just where the best pay is. I do not at all see it as the future of computing.

One reason is ML will help us realize we write code we don’t need; so much of it is syntax sugar for business specific needs; infra, security… it’ll be realized cloud software is solving unemployment not technical problems of value. That many issues with software back in the day were lower quality networks, and consumer hardware. I mean any phone can abstract metadata from any one users amount of behavior, we do it in a DC because that’s where the jobs are. Chip manufacturing will include ML normalized logic for specific application.

LAN IOT will improve and we’ll realize the Metaverse can be implemented with a local client and AI generated art, on a mobile GPUs power in a few years. Middle men like Zuckerberg face the most uncertain future. He failed to diversify as well as Bezos, Newell, and others.

IMO, Valve is a serious threat with Steamdeck; an open IOT brain in a kid friendly form factor could be the new cigarette. Even Apple may have to take them seriously. My kids iPads need replacing soon; a flat glass slab with no interactive controls, requiring another $800+ machine to develop on, bloated development tools, fees, and a bunch of cloud logins, are not going to motivate kids to feel creative.
Whether or not Apple software is better than that of its competitors it's getting worse relative to older Apple software - at least when it comes to macOS. I just had the experience of "upgrading" from Mojave to Big Sur and the number of new graphical glitches and bugs I'm seeing is pretty infuriating. And this isn't some new x.0 release, Big Sur is on 11.6 at this point.

It feels like the macOS desktop experience peaked with Snow Leopard and it's been slowly sliding downhill ever since.

Real time update: Now my Bluetooth is acting up in a way I've never seen before. Thanks Big Sur!
Petty? I could see "cruel", or "clever", or strategic in their subjugation of other populations. It was a calculated tactic, not a petty one.

Here in the US, we mostly slaughtered the natives and forced the survivors into reservations rather than coming up with clever ways of controlling them. Is our way or the British way more petty?
How I helped build a profitable MVP over a weekend
Coffee it's something i have experimented with in the long run.

I went a few months without any coffee and the effects where very positive. Less social anxiety, less irritably and more stable mental energy throughout the day. I could also retain focus for longer periods.

On the other side of the coin i noticed that i became more... boring. To sum it up i became less interested to learn and try new stuff (side projects, trying new technologies etc..).

I ended up settling for a lower amount of coffee. 1 1/2 shot of espresso in the morning and that's it. Still puts me in creative mood but no jitters or crash afterwards.

> Pendulums swing.

IMO that's the key insight in your comment. And the full swing of the pendulum from one extreme to the other can take more than one generation, essentially losing valuable wisdom and letting different generations feeling resentful towards each other.

I never claimed we have it worse in history during all of its recorded parts. I am simply saying that compared to some 60 years ago things are looking quite bleak by comparison, economically and in terms of personal well-being.

No, because you wouldn't have to pay the virtual machine overhead (among others). Another possibility would be using Cython - write the prototype in pure Python, then Cythonize the parts which need to run more quickly.

Right, we may be entering an era in which secure network computing is impractical and the impact could be very far reaching.
Windows in the Ballmer Era, Vista to Windows 8, was a disaster. Windows 10 was released a year after Satya Nadella took over and was an improvement. Windows 11 of the Nadella era is a big improvement. It seems like Microsoft decided to spend the money to get it right to create something stable and pleasing. I've been running it for a month and highly recommend it. I think a big attraction to Mac OS is that the UI hasn't changed much over the years. Time will tell if Microsoft is on board with that. I don't listen to the Microsoft or Apple haters who are always on here telling me one or the other sucks.

In most cases where people are using a PR system as the primary integration point, I've not seen a single PR system that has a problem with sometimes getting the parents in merges backwards. The only time I've seen that is junior developers making merges they shouldn't have been (and are the same developers I would never trust with rebase, even just in their own branches) and there is a way to rebase merge parents if you really want to pull out your rebase fu for something.

> Also, "git praise"? Is that really a thing now? Talk about not understanding programmer humour.

git praise has been a standard git alias for git blame for several years now. I'd prefer if git had followed most other VCSes and named it git annotate rather than making it a micro-aggression out of the box, but yeah one person's micro-aggression that makes a papercut in daily workflows is another person's punch down "humour", I guess. I'm glad you seem to enjoy it, I don't appreciate it.
I doubt many billionaires have income. Although you're partially right, I'm not sure which is a better metric. Probably depends on where in the distribution you are (above or below the median).
See my reply above: in-memory data analysis…
This is the real answer. Nothing else is going to change that. A basic lifestyle isn't that expensive and it's exponentially better than 99% of people's lives 50 years ago. Just making smart shopping decisions can literally double or more your buying power.

I really don't get the point of doing something you don't enjoy for 8-12 hours a day just so you can have expensive things.
I was talking to an artist a few years ago who seemed to downplay the significance of her art as we discussed the paths of lives we each took, she a traditional artist and I a hacker.

I had to quickly remind her that the importance of her art was substantial because it helped other people see ideas and other unseen things clearly. We need this in our communities and societies more than ever.

I love this idea because those with good taste can show layers of depth through their art much better than those with poor taste.

It's on the order of 1.5%/1,000KM, so something like 20%-25% loss.

Yeah he is really good at game development but he is even better at game business handling than most of the people out there (including me). I think he also shared some of the revenue numbers and you can see they are good, but never good enough for retirement. That's the best an average indie developer can get IMHO.
Wikipedia gives 3.5% loss per 1,000 km as a ballpark figure.

There's no reason the code couldn't just blindly try every attack until it finds one that succeeds. If there's a malicious app that runs a lot (lookin' at you, random firefox tab that eats 99% of my CPU for minutes at a time and then goes idle again), it has all the time in the world.
>it seems that you and the postmodern crowd both value highly the creation of a shared narrative about what's important and what's going on

This is a fairly widely mocked opinion, it;'s the same caliber of criticism as the "we should improve society" meme. The fact that both sides participate in shared narrative isn't a sign that both are corrupt, it's a sign the narrative is important.

As an anecdotal example that may be relevant, I wanted to upgrade to Monterey and my Mac Mini said there wasn't enough room.

Hooked up a Western Digital external drive that I had used on previous Macs and launched Time Machine. And that's when it started. Time Machine presented what seemed like a stack of Finder windows in the middle, a timeline with hash marks on the right-side and the only button highlighted was the "Cancel".

No menu, no other actionable buttons, no right-click menu. Nothing. So after hitting various key combos and mouse buttons, I decided that my 30+ minutes trying to use Apple's built-in backup software to backup a few folders was better spent finding 3rd party software.

And that was another user experience fail in my opinion for Apple and any "total quality" experience.

And that's not even talking about Safari or XCode or Pages or Numbers or iBooks not syncing and so many others.

This is the reason I am not at all concermed about running up the federal deficit to fix infrastructure. We can put future generations in debt by taking out loans, or we can do it by sticking them with a massive repair bill.
>Alcohol is a poison that offers short term fun for long term sadness and pain.

Alcohol in excess? Certainly, but I don't buy the idea that alcohol in moderation is harmful.

There have, of course, been studies that draw negative conclusions about alcohol, but they either commingle societal effects or discount the cardiovascular benefits.

TLDR: Alcohol in moderation is fine. Just don't drink to excess. Nearly all the negative impacts of alcohol are on a J-shaped curve that increase exponentially beyond about 20 drinks / week, and that is far from 'moderate' drinking.

Ask HN: Could an AI be the sole proprietor of a company?
I imagine a situation where I anonymously create a bot that is able to maintain and run a successful business (current tech notwithstanding). In the course of its activities it begins to accumulate wealth, in the form of cryptocurrency, to avoid traditional non-human exclusionary banking routes. Assume nobody could trace it back to me and it was extremely persistent (decentralized botnet-type of agent).

Would the government outlaw engaging in business with the AI? If the AI was creating and accumulating real wealth that contributed to the economy, might the government instead adapt to this new type of entity? Could it lead to automaton rights, ie allowing them to own property and engage in contracts?

I see the clichéd grey goo/paperclip maximizer scenario, but that one is a little less interesting. More interesting problems would be things like whether humans could act in concert to change the AI's incentives on the fly. If an agent is disembodied, then that precludes the use of the "monopoly of force" by governments. Cryptocurrency also makes asset seizure difficult if not unfeasible. Would competing "regulatory" AI's need to be unleashed?

My post was sparked by the rumours that dang is an AI. He denies it.

As far as I can tell, Cloudflare Access doesn't allow you to run arbitrary code in an environment that isn't exposed to the user, which is kind of the whole purpose of this setup. The sole purpose of the OAuth part of this operation is so that the user doesn't have to type in their email. Session persistence/selective access isn't relevant here, and that appears to be the only thing the Cloudflare Access really offers.
Linux doesn't change my settings for me, I don't know why people continue putting up with changed settings and advertising in a piece of software they paid for.
> cloudflare actually decreases performance (by adding an hop when serving dynamic content).

Page load time tends to be dominated by static content.

But even for dynamic content, this isn't necessarily true. Setting up a TLS connection requires multiple network round trips. When using an edge network, those round trips only need to go to the nearest PoP rather than all the way to the server. If the PoP already has connections open to your server (which is probably the case if you have consistent traffic) then the network round trips back to your origin server are avoided, and your dynamic content ends up being served faster.

Additionally, Cloudflare's Argo Smart Routing is often able to route packets across the internet faster than than default network routing, which speeds up the communications between Cloudflare and your origin server.

So it turns out "adding a hop" does not necessarily decrease performance.

(Disclosure: I work for Cloudflare.)

Doug Stewart, now at VEIR (veir.com), had a company (Wattershed) that was doing undersea HTS cables about a decade ago. I think their first deployment was going to be inter island in Hawaii?

Either way, this doesn't have to be hyper efficient. It just has to be better than "get lots of batteries". Like others, I'm more worried about redundancy / operational concerns than about power loss.

I dont think this makes much sense - even if the fundamental premise (sending solar energy under thousands of kilometers at massive initial and maintenance costs) had immediate economic merit, there are closer places like Australia.

Even then, the fundamental benefit of solar energy is it's distributed nature. With something like nuclear power, however, there might be more use...

The way you've phrased this is rather beautiful, in that it suggests that good art is art which matches the intent of the author.

Some artists seek to recreate the world around them in great fidelity, and if they succeed in producing photorealistic paintings then for them, that is great art. Others seek to stir up controversy or draw attention to some cause, and if their work achieves that then that is great art. Others may simply seek to express themselves, or find peace with their feelings, and if they succeed in this then it is great art.

This is of course a different definition than Paul Graham would use. It does not allow for so much judgement and comparison. But for people interested in producing art, rather than consuming it, I think it's a much more useful perspective.
