> In Europe it is distinctly less risky as you get arbitrage between different parts of the grid. You make money as long as their is a price difference.

Yes, and in theory, the market can decide whether spatial arbitrage via long interconnections or temporal arbitrage (via batteries, shutting off industrial consumers, pre-running air-cons, etc) is better.

Perhaps a combination of approaches will prevail:

The different arbitrage opportunities mostly make money off the price spikes they can smooth.

Simplified: the first long range cable you install earns the most money, because it can pick off the highest spikes. The second cable will cost just as much as the first one to install, but will have to find its profits in a world with already slightly blunted price spikes.

Similarly for batteries. But eg batteries and long cables can pick off slightly different spikes, and the back-and-forth flow in cables doesn't have to average out to zero (like batteries do).

Human, I'm 28, been in InfoSec for ~10 years. Granted, I was lucky enough to be interested in and peruse this as a professional branch when I graduated college in 2016. I am also an adjunct professor at my local university, where I make it a salient point to remind my students of the history of hacking. We talk about this still.

I also start every semester off with the opening scene of Hackers - the best hacking movie ever made :)
Ah yeah that seems to have a bunch of neat stuff too, thanks for sharing it!

I got into my school's network when I was 10, people were furious for my hacking, nobody questioned why was there a security issue so obvious that even a 10-years-old could break in.
Few years later I accidentally found another way to get in. I sent an email to the school's IT department, got ignored. I sent it to the headmaster, he said "Thanks, will fix it". Except it was never fixed.

Maybe fixing the child is easier than fixing the software.

Only if you are writing multithreaded coded. Otherwise it is just a loss.
Would a “number of reroutes from original” metric catch this or does that have too much noise?

Or even a “amount of time to complete trip” vs “predicted time”.
In most of the rest of the country we manage to build new roads and new transmission lines without the extreme issues you're describing. Over the last few years, I can think of hundreds of homes and businesses near me that were moved to widen existing roads or build new ones. A few people/businesses tried to fight it, they all lost quickly.

You can't take the experience of a private citizen trying to clear some brush, bridge widening delays in one of the most regulation heavy states in the country, and oil pipeline opposition, and apply it to building HVDC between countries in Europe.

Unlike your examples, HVDC lines have no real negative impact on anyone but the immediately impacted property owners. If you're building HVDC transmission lines between countries, you can also very likely reuse existing utility corridors for much of it, and build through lower density areas for most of the rest. The actual number of property owners directly impacted won't be high enough to make an impact on elections.

So the car is going north on 15th between California and Lake. It wants to turn left on Lake but can't because of the slow street sign. Why doesn't the car turn right on Lake instead going straight into the dead end road?

Also Google Maps seems to have the slow street marked. Do Waymo cars not know about that? If you entered the desired route into Google Maps, what way would it take you?
There were a lot of 3D globe products being created in the 90s.

I was one of the creators of Electronic Arts 3D Atlas which shipped in spring 1994. It sold two million copies on Mac and won many awards.

EA was the publisher but we developed it in London working at a BBC spinoff called MMC and getting the planetary data from UCL. This UCL unit eventually spawned Planetary Visions, a startup we worked with to supply data.

That wasn't even our first 3D zooming spinning satellite globe product. We did a huge touchscreen installation for the Kunst und Ausstellungshalle museum in Bonn, Germany. It was called "Erd Sicht" (Earth View), and in the early 90s had amazing satellite Earth graphics and animations.
I am saying passive safety can’t assume anything else worked.

It's great if it's working for you. I've been in that mode in the past. I was greatly productive and was able to grow businesses and do amazing things doing 80-100 hour weeks. Building highly complex systems alone in very short amounts of time.

It also gave me incredible sense of achievement. What I can say is I'm getting older now and I can say that my body ain't the same as I was when I was in my 20s.

Enjoy it while it lasts!
The regulatory system makes them ESSENTALLY IMPOSSIBLE. Seriously, if people only knew how fucked up the regulatory system is.

Unless you are NASA or DoD you can fuck right of with that stuff.

The regulatory system is HARD LOCKED to one technology. No sane person would invest money in an alternative (unless you are planning on selling it to DoD). The regulatory system had to be changed a huge amount, just for NuScale PWR in a module reactors.

If you wanted for example to build a Molten Salt reactor there is no established regulatory path. Or a small reactor either. There is only tiny research reactors, or fully operational reactors. So you can't even build a small version of your reactor to prove things out. No prototyping for you.

You would basically have to show up with a full design (literally invest 100s of million) then go to the regulator and hand it in. You would also pay them to review and you would literally have to wait years, and potentially decades for them to tell you if your design is good. You would get no early feed-back on what they might consider problems or issues. And there is no criteria what exactly the application needs to look like or how much detail they want and so on. There is no established software that they accept as valid for modeling something like uranium in molten salt. If you are not providing real data its very hard convince them on anything, but of course, you can not actually get real data from anywhere.

That is why essentially no progress has been made. Thankfully in the last 5 years or so, actual progress has been happening and the regulator has admired that there is a problem. The don't have actual solution yet but they are apparently working on improving the situation. That is why, almost all GenIV nuclear startups have converged on Canada. The Canadian regulator after its privatization of CANDU was looking for something to do and they were very open to next generation technology. Their regulatory process is a multi-step process that is technology independent.

It looks like US regulator and the Canada regulator are working together so hopefully Canada can lead the US out of its idiocy.

What you must realize is that the turn against nuclear was hard, on all fronts. Population, Politics, Regulation went totally anti-nuclear and specially for anything that wasn't established. Since Nuclear Commission was abolished, progress has been glacial.
Economic progress means doing more with what you have, and the reason why economic growth is exponential is that you are creating more capital as part of the production process.

Open Simulator wasn't something I expected to see on HN.

Open Simulator checks off almost all of the boxes for the "metaverse". Multi-user 3D world, check. User-created content, check. Open system, check. Interoperability between servers run by different parties, check. Anybody can run a server, check. Compatibility with external asset storage systems, check. Compatibility with external payment systems, check. Second Life itself isn't as open.

So why isn't it the metaverse?

Well, there's a problem. It's not "fun".

If you start up an instance of Open Simulator, you get a blank piece of terrain. You can log in and visit it, and so can others, if you let them. Now you can build things. You can import assets and place them in world. You can sell or give parcels to others so you can have neighbors, who also can build.

This appeals to the fraction of the population which needs an outlet for their creativity. People who probably have a workshop or a drawing pad or a software development environment or a CAD program. It's not a passive form of entertainment. This makes it niche.

That may be a generic problem with the "metaverse". People don't actually go to any of the NFT worlds much. Decentraland runs about 200-300 concurrent users. (They hit 350 today!) Sominium Space, maybe 25. Most of the rest are vaporware at this point.

Attempts to make metaverses fun mostly so far involve bringing in DJs, or adding gambling.
You need something fun for new non-creator users to do the first time they log in.

You can put games inside a metaverse. That's what Roblox is. Roblox is Youtube for junior game developers. Upload something, compete for attention and revenue. Open Simulator and Second Life are a bit too sluggish for that. Mostly because of dated implementations.
Open Simulator only has one real maintainer at this point. Linden Lab has a new VP of engineering who's trying to increase performance, but he's facing a long-standing corporate culture of "can't do".

(I've been working on an SL/Open Simulator client that uses Rust/Rend3/WGPU/Vulkan, and can get consistent 60FPS frame rates. But it's nowhere near feature complete. The performance problem is solveable through parallelism and some algorithms that turn O(n) into O(n log n). The fun problem, I don't have an answer for.)
What I really dislike is that not only Google sends its mapping cars into the private-drive-no-trespassing, but they've also somehow managed to map gated-no-tresspassing pedestrian walkway. And now we have people literally walking in into our backyard, following Google Map's directions.
Thanks! I was thinking too vaguely of “hash”, and didn’t think about the requirement that the hash of something large and the hash of that thing but with a big chunk of it replaced with , uh, the hash or some kind of digest of that large bit, be different.
I keep seeing Tailscale come up and I’m sure the UX is great but I’m not really sure I get the value-add compared to normal WireGuard on a cheap VPC. Like it took like 30 minutes to have a WG server and profiles for all my devices. Scanned a few QR codes and now all my devices can all mutually talk to one another.

Sure it’s not fancy P2P with lots of NAT busting tricks but the upside is that it always works. And I don’t need a fancy privacy preserving relay because I’m the relay!

Automating all that stuff I’m sure is worth the price of admission for large deployments but for personal stuff I don’t get it.
I did it just fine for the cost of the license of Working Copy syncing to a iCloud folder. But the Obsidian license still made me end up going over to LogSeq, which works better for my mental model.

i can concede that attempting to censor content is generally a poor remedy, for society at large. however, the notion that netflix should then fire the employees without discussion or recourse is just as egregious. let’s get past these superficial aspects, otherwise such discussions are useless.

> We've seen prices becoming more volatile in later years as our domestic market has become more interconnected with that of continental Europe.

Differences in prices both between locations and over time can be turned into money. The first with cables, the second with batteries. In the process, the arbitrager smooths out the price differences.

Give it a bit of time, and you'll see more stable prices again. (Unless politics throws a spanner in the works, of course.)

> It would be nice to serve base power needs by nuclear power, then use hydro (which can be regulated up and down much faster than thermal power plants) to handle the peaks.

Oh, and don't forget the ability to regulate demand up and down. Plenty of industrial consumers already have contracts like that, and thanks to 'smart' devices, this technology can come to private consumers as well.

Eg assume your short term weather forecasts says that we have plenty of wind now, but there will be a lull in fifteen minutes. So you just tell all the fridges and hot water tanks to cool respectively heat now, so they have some stored thermal energy to get over the lull. Similarly for electric cars charging (you don't even have to take energy out of their batteries back into the grid, it's already useful to be able to suspend their charging for a while and resume later).

This is mostly not a problem of high technology, but a problem of coordination.

In principle, you also don't need your power company to directly talk to your fridge: whatever controls your home just needs a short term forecast of electricity prices in the next few hours, and can then decide autonomously and in harmony with your preferences.
If you're saying the world is overpopulated by X then you're saying X amount of people who exist shouldn't exist.

No matter how you paint it, you think it is a good thing for you to exist but not others.

"Balance of health, nature and economics" nice words for basically "I want fewer poor people in the world so let's help them sterilize themselves" instead of creating wealth which isn't inherently immoral and would actually have a positive impact if done rightly
To me, Macbooks have the worst trackpad 'feel' so hopefully it's nothing like that.

Euclid.

The Elements may have been meant to go through a teacher who'd help you connect to it, who knows? But the text itself is totally definition, theorem, proof, repeat, and that's all that survived to reach us.
> Zuck is crazy and he assumes everybody is sick in the head like him!

What an unnecessary and aggressive comment. Also, how is the meta verse indicative of someone being "sick in the head"?
Yea, I'm afraid that's not so. In 1993, I was running a WildCat BBS and I was way more hyped about that and it's RIP graphics, lol. The only way I could get on the internet at all was through other peoples university accounts, which required dial-up, Trumpet Winsock, and PPP. It was a chore to get running and was very slow on the 14.4k (and slower) modems of the day. 56k modems weren't introduced until the late 90s. So yea, between 90 and 95 other technologies seemed more appealing like BBSs, Gopher and places like "The Well", at least to me.

It has something like 100% availability throughout the day, yes.

But throughout the year capacity varies.

And, of course, there's only so many sites that can support dams. So you have to ask 100% of _what_? And is that enough?
Did you use stdfix, another library, or just hand-roll it?
If you're going to apply "passive safety" globally, sure.

But what we're talking about here is passive cooling system safety, not that the entire reactor is passively safe. The multiply-redundant shutdown systems suffice to end the chain reaction.

If the chain reaction ends, you're pretty much immediately at 7% of decay heat -- so sure, a 1.5GW reactor will put out 100MW of decay heat, still. But this will rapidly fall off. After about an hour, it's more like 15MW; after a day, 6MW.

Your statement of "200MW of decay heat" days later assumes either a ridiculous initial condition (an implausibly large reactor) or assumes you still have an operating reactor, which... isn't decay heat anymore.
Careful there: you might mess with the salt and mineral concentrations in the Mediterranean Sea. And, of course, there's lots of shipping through the straits of Gibraltar that you have to accommodate.
Somehow? They likely mapped it from aerial imagery.

It is trade off. Pure single threaded code is worse in exchange for much better multithreaded code. And the current sentiment in the python dev mailing list looks positive. Previous attempts at Gil removal had much bigger drop in single threaded performance.
Yah that has been my thinking on this too. The Metaverse is in its dialup modem stage of the comparison and things can still take a number of directions not all of which favor Facebook by a long shot. They are the ones investing heavily today (FBRL is already 10K people [1]) and that brings legitimacy to all of XR as more than just a gaming niche subculture. But, as any comment thread on this topic clearly shows, FB has sustained reputational damage that is not easy to overcome without some internal soul searching business model pivot. If they plan thier Metaverse as an Adtech engine extension of their existing business, then they can be AOL/Netscape - big names at the outset but not built to last long in the new space. Given the choice, people want some Digital Dignity/Data Sovereignty and other players will find a way to make it happen if FB won't.

Well, I'd gladly be one of them.

I have a strong disagreement with the current HN hivemind over the "evil" of Facebook. I'd put them at equal levels of "evil" with the rest of the AANG.

That and I'm personally invested in the metaverse. My whole life I've been wanting virtual worlds, inspired by the virtual-virtual worlds oft-portrayed by media. By some twist of fate, it seems that my generation might very well be the one to get that.
I'd work for a company that had done bad stuff if I'm not contributing to it - even better if its providing an alternative path to profitability that may reduce reliance on their "dirty" money. This seems like a desperate ploy to find "another thing" for Facebook to escape their past/present - and they should move on from it.

Few companies are benevolent and have never done something wrong. Apple and the CSAM is only the latest bad story for them. Google and privacy and dragonfly. Amazon and warehouse workers. Facebook and... Facebook. Microsoft and antitrust/EEE.
the company should use this opportunity to move the ball forward wrt deeper, mutual understanding, not retaliate with mass firings (which is the recommendation i was responding to). that’s escalation, and does nobody any good.

Just adding an incredibly larger amount of gases (the atmosphere is 5.5 * 10^18 kg) in the air doesn't increase global air pressure, it will just make more gases leak into the outer atmosphere over time. I am not sure how long that would take though.

Anyway, as you said, any project that doesn't involve significantly scaling down anthropic GHG emissions and human settlement footprint will have significant effects. Planting trillions of trees will result in dead trees and environments destroyed. CCS at scale will involve ungodly amounts of energy + materials. Algae farming will alter the ocean's biodiversity already affected by warming + acidity + overfishing.

It's time to acknowledge that the Earth doesn't owe us a couple of large cars per household, exotic foods, meat BBQs and regular plane trips.

I remember that the binary for L0phtCrack had some sort of software protection included with it, and it took a 1-bit change to be cracked, itself -- a 0x74 to 0x75, iirc (or 0x74 to 0xEB if you're a stickler for doing it right). I don't remember exactly what the protection was, maybe there was some sort of password count limit or time limit. It was a long time ago. I just remember being a little disappointed that it was that easy.
Glad I'm not the only one here who does not like this company. When thinking about companies I wish I could easily boycott, Nestle comes to mind, and then there is Sinclair.

If the OP is an ex-AAA graphics programmer, DX12 is probably more familiar than Vk. AAA likely means consoles which at the very least means you end up doing DX12x for Xbox, and at that point you may as well also do DX12 for PC.
