In addition to hydro and fossil fuels, (most) energy storage setups are quickly dispatchable.

I don’t think the question is “is natural gas better than nuclear?”. It’s more “nuclear isn’t quickly dispatchable, which is what we need”. It’s not that gas is better than nuclear, it’s that they solve two different problems. Solar and wind need something to fill gaps when production fluctuates. Today that can be hydro or fossil fuels. In the near future, that will also be storage. For the foreseeable future, nuclear can’t fill that role.

Demand response is an interesting concept, and a subset of researchers have been pushing it for years. I’m skeptical that the economics would work out (large fixed costs mean that there’s pressure to run 24/7 and eat the high electricity prices), but I’d be happy to be proven wrong. That said, it doesn’t fix the fundamental problem that sometimes the wind dies at night, and something needs to turn on in the next 5 minutes or streetlights start going out. Right now, nuclear isn’t capable of filling that niche.
>Since ISPs generally see DNS queries from the gateway and not individual hosts, wouldn't your ISP still be able to see those requests?

Of course. Just as they can see every other packet that comes out of my network.

>AFAIK, the only way to prevent your ISP from collecting the domains you visit is if you use something like dns over https. Even then, you're tls connection leaks the domain via sni (hopefully this hole will get plugged by tls 1.3).

Actually, they can capture or log all your network traffic if they want, not just DNS traffic.

As for DoH/DoT, that's a huge can of worms that I dislike immensely. Why? Because it uses tcp/443. As such, any device that I don't roll myself (roku, fire stick, etc.) could (and with wider adoption, will) perform their own DoH/DoT requests that I can't intercept with my network-based ad/tracking/spying blocker (e.g., Pi-Hole).

That means that blocking ads/tracking is going to become enormously more difficult, unless I block tcp/443, limiting my ability to connect to pretty much any website these days.

And I am much more concerned about that than I am about my ISP logging netflow[0] data, or even capturing all my packets.

What's more, they are extremely unlikely to do the latter. Even with cheap storage, capturing all my packets (and even just the hundreds of other customers that connect to my head-end, let alone the millions of customers they have) isn't economically (or likely even physically) viable.

That said, if you're afraid that your ISP might be doing so, I suggest using a VPN. Then they only see the envelope of the encrypted VPN traffic and that's it.

Given that most data is going to be encrypted anyway (https, ssh, etc.), the fact that they can see where I'm going (which they need to know anyway to route the packets) doesn't really concern me.

As such, if my ISP really wants to capture all my DNS queries and other network connections (assuming they do so for all their customers, as I'm not anyone state-level actors are interested in), they're going to need some ginormous data centers for all that data storage.

Yes, NSA has their ginormous data center in Utah, but they're pulling data from Tier 1 peering points and nothing I do will impact that -- not even using a VPN.

As I said, I'm much more concerned with ads/tracking/spyware, as that's much more likely to be tied to me personally, as those folks want to maintain the fiction that they can effectively "target" advertising at me so they can keep charging the advertisers more and more.

So unless you're someone who some state actor wants to mess with (in which case, you're hosed anyway), blocking the corporate ad spies is more useful than worrying about your ISP. I'd note that Google is one of the biggest of those spies too.

As such, I'm going to focus on a real threat to my privacy that I can actually do something about (which includes doing my own recursive DNS queries), rather than worrying about stuff over which I have no control.

I'm not telling you what to do, just what I do.

almost all politicians are using "climate change" as a fear based method of controlling the masses. nuclear would do to much damage to the narrative.
I'm also on venlafaxine, and have been for years. I've recently (4 months) started MMJ for my chronic pain, and it seems to offset the sexual side effects of the Effexor: (1) I have a libido again (2) I always finish now (3) and it feels pretty damn good.

The 3rd needs explanation for those who haven't experienced it; one nasty side effect is when you orgasm you ejaculate and feel NOTHING. It messes with the male psyche in a big way in my experience.

And variability is easy to deal with: overbuild and/or storage.
Southern Australia shows how it is done.
What a dissappointment. Nuclear (of some kind, hoping for Fusion later) is a key component of any plan to stop global warming. Solar and Wind can get you to a greater than 50% green power production, but as you get closer to 100% you need exponentially more and more production and more and more transmission lines to handle dips and avoid blackouts from rare situations. You need a power generation source that is consistent.

At some point in the future we may have enough battery production for grid energy storage such that nuclear is not needed, but we are a long long way from that. Battery supply is growing rapidly, but not nearly rapidly enough.
You're missing a lot of background on how these markets work. And i'm not remotely qualified to explain them.

But, very broadly and simplistically speaking.

We are not even remotely close to living in a "We have too much power" world. ( Markets will change drastically then.)

All the nuclear supply has already been sold and is being constantly used 100% of the time.
It never makes sense to turn off the nuclear power plant.

There is more demand then that, not meeting the demand is catastrophic.

If a popular sports is on TV and halftime everybody boils water,
or the wind is unexpectedly low,
or some part of the grid is having trouble.

We must still meet the demand.

Turning on a gas plant is the cheapest solution we have at the moment.
Renewables and gas are not enough either: you need lots of storage anyway. Plus, at this point you’ve lost the plot because you are still burning fossil fuels. Without nuclear there is no scenario in which we stop carbon emissions without seriously decreasing energy consumption (about an order of magnitude in 50 years) or paying significantly more (tens of billions per year) and relying on hypothetical future technologies.

The arguments against nuclear are not really technical, and are overall incompatible with our energy supply getting rid of fossil fuel in the near term.
People are being defrauded of magic numbers, not money.

It only just so happens that a lot of people with time and money on their hands want to trade magic numbers, which they deem to be worth money, but as long as they just a kind of fiction, then why we care?

Why should the US government spend valuable time, effort and energy hunting down the scammers among the hyper speculators taking incredible risks with their money with no benefit to anyone?
Probably useless in the browser, but who uses octal in general? I assume it's still important in some areas (networking?) but I don't actually know.

Eh, it's very outdated. For example, "YouTube Plus" was sold by the author years ago (to shady party no less) and "Iridium" is his new endeavor on Y2B enhancement, which was also abandoned.

To be honest, I don't think there is any point to include specific scripts to begin with. https://greasyfork.org/ probably is a better place to find them.

Just list all the "meta" sites (toolings, host sites, articles) about userscript is probably better and easier.

On a side node, if anyone has resource about how to dev/debug userscript properly, I'm all ears. I found it super inconvenient and tedious when doing it myself, and I often have to manually copy paste stuff back and forth.

> We did obey and suffer the lockdowns. We did get the vaccine. But it certainly doesn't look like we're getting our liberties back.

Security, whatever form you consider it, has not taken a step back since the end of the cold war. What reason or incentive could we possibly give already empowered people to be less powerful?

Two years of complete or near complete communication monitoring combined with the patriot act is going to influence our society going forward for decades. This enormous feat of surveillance was done with little trust in oversight.

> I don't personally think the pandemic warranted such a totalitarian crackdown on citizens.

This thought is way too vilified and used as justification for extensive monitoring. Though we survived the resulting fallout of the entirety of pandemic measures I'm not sure many will agree in what form we want to continue.
Nice wallpapers but would be way more helpful if they actually opened some windows for the screenshots.
If the assumption is that the major world powers don't cooperate enough to tackle a global existential crisis then we're fucked even without someone bombing a nuclear power plant.

Nuclear is currently the only viable option for buying enough time to address all the other negative consequence of 2C+ of warming. All the other plans currently on the table are accelerating us towards 3C of warming and that essentially means human civilization as we now know it is over.
and the pro nuclear hacker news cohorts are already on their way down voting.

False. We learned that an agrarian society can resist democracy and nation building. They were incapable of withstanding military destruction. They didn't even last 90 days.

In fact they've already destroyed the military infrastructure we left them. "Soldiers" are literally parting out $20 million helicopters for $10,000 in scrap metal.
It's not palatable because of poor education. We need to be including nuclear in the list of green technologies in basic school science textbooks. We don't.
Conversion of carbon dioxide to calcium carbonate (one of the materials found in shells) has been researched:

https://www.frontiersin.org/articles/10.3389/fenrg.2017.0001...

Using the exact technique that crustaceans use during biomineralisation will be very, very expensive at scale due to the enzymes needed. Current techniques involve using high-pH hydroxide solutions to perform the reactions. Carbon sequestration by pumping concentrated carbon dioxide gas underground would naturally use the high-pH geological environment to run this reaction over time.

There are still unanswered questions about pumping CO2 gas underground with regards to leakage - nevermind the fact that when it's pumped into old oil wells, it has the side effect of forcing out more oil which is recovered, sold and burned.

Converting CO2 to a solid, stable form like CaCO3 then storing the solids is a nice sequestration option, but like a lot of things in this space, the economics are holding it back more than the technology is.
My GP told me that having a strong sex drive is normal for men in their 50s, so I suspect you might be experiencing the meds...
So a lot of the discussions here are around EU or US opinions about nuclear power. The problem is something entirely different.

India and China will move to emphatically reject coal restrictions during COP26. Remember India has probably some of the largest investments in renewable rightnow. But I dont think people outside of these countries have even an idea of the amount of hunger for power that is being generated as huge populations start clawing out of hunger and poverty.

3 years back, there were 240 million Indians who had NO electricity - https://www.bloomberg.com/news/features/2017-01-24/living-in...
So talking about pollution in this context is only solvable through large sources of clean power. We dont have enough land in India to support renewables for 1.3 billion people. Neither does China. Europe ? Very easily so.

Coal ban is not an option. Unless nuclear power and technology transfer is on the table.

India and China have both rejected targets - https://www.ft.com/content/eef90c01-4cbe-48b7-8b2c-2beb398a4...

COP26 basically seems to be a non starter now. with coal being pushed back in and nuclear pushed back out.
What about drilling for geothermal energy? And what about thermal fusion which is upcoming? For what do we need fission any longer, except to bridge the time up to availability of fusion?
As long there is no good concept for the nuclear waste, that long nuclear shouldn't be praised as solution to anything, except for bridging.

There have been news on here, for a newly developed technique to "recycle" and/or to "treat" the nuclear waste by utilizing a collider. May be this is an solution for the nuclear industry? Safety of the power plants is, I think, comparably given by learnings of the accidents in history. Which shows quite a lot of incidences..
It's difficult. Me dunna want to have the power to decide on here.

They're not "nuke plants". "nuke" is a word that means "nuclear weapons".

Secondly, they're heavily surrounded by highly reinforced concrete with extremely high levels of security. The furthest any activist with a bomb belt could get is jumping a fence and getting immediately caught. Even if they could drive a truck through the front gate and set off a car bomb, they're not getting through the extremely thick concrete.
> Facebook was famously started and hosted in a dorm room. But this was only possible due to the history of Harvard within the advent of the internet and the fact that they had such an excess of addresses that Zuck could bind to a public IP address.

I'm fairly certain the version of Facebook that was hosted from Zuckerberg's dorm room was just for Harvard students, and wasn't accessible from outside the campus network. Keep in mind that early FB was rolled out to only select universities on a campus-by-campus basis over the course of a year or two; it wasn't like it was today. Part of the whole appeal of FB early on was its exclusivity.

There were and are lots of places with routable IPv4 addresses that still have various kinds of traffic management and firewalling. My uni handed out real IPv4 addresses in the early 2000s (may still today!), but absolutely didn't allow inbound connections from anywhere outside of the campus network, at least not on well-known ports. You could (and lots of people did) run a server, SMB or AppleTalk file share (so much porn...), etc., but it wasn't accessible to the entire Internet. (Hotline and Carracho servers, OTOH...) I would be absolutely astounded if Harvard didn't have some inbound filtering on its network at the time; keep in mind this was 2004: peak Windows XP era... students would have been getting hacked left and right if they hadn't.

There are still some big companies around with very large IPv4 allocations for historic reasons (HP has at least two /8s I believe, its own original one plus one acquired from DEC; IBM has at least one; Apple has one, etc.) and some of them use routable addresses internally. I know IBM did this in its major offices in the mid to late 2000s. But you couldn't just spin up a server at your desk and hit it from home without going through IT and having them put in a firewall rule for you. This was all pretty standard network security stuff at that point.
I was referring to the social norms around criticism of authority. There is a much greater expectation of tact and constructiveness compared to the West.

The Singaporean government is doing the wrong thing by executing this man, but GP's flippant remarks were not the way to express this.
>But mainstream empirical economics, including (but not limited to) the neoclassical school, does not have a theory of value.

It does; it assumes utility exists as some concrete thing that can be compared between individuals. The fact you weren't aware of that just shows how good mainstream economics is at hiding this. https://en.wikipedia.org/wiki/Utility#Discussion_and_critici...
Do you have a source for this? To my knowledge, uranium would run out in a decade or two if one would use it to supply 100% of the world primary energy consumption [1]. Coal is obviously way more abundant.

Yes. This is a huge win for coal lobby. This might be the turning point that kills humanity.
Unpopular opinion in this thread but ... I don't want a world with nuclear. That makes me anxious. It's not if there will be a problem, but when.

I'd rather the world spend money on batteries and solar/wind energy, like South Australia. And by focusing on that technology, the market will drive innovation in that class of renewables. That technology is reusable in other applications, like domestic (rooftop), EVs and Space.
We suck at risk assessment. We fret about radiation whilst fossil fuelled power plants have been releasing radionuclides and particles in the open air for about a century.

I would strongly second the GP's recommendation. The book mentioned is aimed at math teachers up to an undergraduate level, but generalizes quite naturally.

The idea is that one may induce a path to solution in a student by stripping a problem down to it's knowns, unknowns, and constraints so that it may be comprehensible, then connecting these elements back together by asking pointed questions that could have conceivably occurred to the student. He gives plenty of practical examples of how one may dial the complexity of these questions up and down, how to relate by analogy, and plenty of other techniques for approaching problem solving generally all in a flimsy paperback that can be finished in two evenings in a weekend.

The most impressive part, to me, is that nearly every example is both illustrative enough to be a word-for-word guidebook for math tutors, and accessible enough for even a middle school student studying Euclid to understand in it's entirety.

SigNoz (YC W21) Is Hiring Golang Engineers
What happened with France?
That's an interesting question, actually, and the numbers seem difficult to come by. A master's thesis from 2011 says[0]:

"data on the amount of rare earths in wind turbines vary, ranging from 0.2 to 3.3 kg of neodymium content per kW of rated capacity"

For comparison, a nuclear power station generates[1]:

"24,000,000 kWh from 1 kg of uranium-235"

So, taking the lower estimate for the neodymium content, the wind turbine would have to produce energy for 0.2 x 24,000,000 hours to be as efficient in terms of mass. That's about 548 years. Even with recycling, that's a longer term commitment than some nuclear waste storage proposals, although with less of a proliferation risk.

OK so I just watched the clip and no that's absolutely a conspiracy of wastes of a fuck 100%. They do everything. They insult him, they click his fingers at him, sure he asks for clothes in the imperative but if you don't know the rest of the plot it could just be a weird naked guy asking for clothes, I've seen people in tough situations make much worse requests. I saw some in SF for instance, really gritty scene I remember a crack addict at a wondrous and cheap Chinese food restaurant named Quickly. He said crack cures hunger, over and over, like that was what he was going to eat, and he was there because he had no crack, so he needed actual food to cure his hunger. So in SF people ignored him, but in this clip the losers say "Fuck you, Asshole" and then all three take out a switchblade with the camera focussed on the blade opening, and they guy's naked, one of the losers stabs him, at this point you don't yet know how hardcore the Terminator is.

So what this film is doing is using a small wannabe conspiracy to raise the status of the true villain of the movie. But there's no intention of the losers being the good guy, at this point Arnold's the closest to being the good guy.
OK, lots of downvotes and no replies. HN becomes very toxic these days.
I am a fan of nuclear energy for various reasons, and it's obvious that the safety and waste problems can be solved with new technology like small modular reactors with inherently safe designs.

However, even I realize that nuclear energy is not viable to significantly combat climate change due to the following reasons:

* The technology is not there yet. There are a lot of promising companies that are trying to solve the safety problem, and there is a lot of research on how to better deal with the waste, but due to the inherent dangers it will take decades to prove these designs are safe, work as intended and can be produced at a significant scale at the promised cost. Sadly, we don't have decades, we need to start replacing coal right now.

* nuclear energy is way to expensive. Wind and solar are much cheaper. current numbers are roughly 50% cheaper for renewables, and while lots of companies promise cheaper nuclear design, these claims are unproven and the renewables are also still significantly improving in cost. The nuclear cost models I've seen also ignore most of the storage and security cost for handling the waste for millenia. There are cheaper alternatives with existing and proven technology. Power to gas for example has an efficiency of roughly 50%. which funny enough corresponds to its cost advantage over nuclear. simply building a lot more wind and solar capacity and using power to gas to fill existing gas storage systems with excess energy from renewables has roughly the same cost as nuclear, without the safety and proliferation headache, and the added advantage of long term storage.

* proliferation. even if we could solve the problem of safeguarding thousands of SMR in developed countries, you can't just export them to every country on earth. however, that's a requirement for replacing coal, as those countries need to reduce emissions, too.

So yeah, I'd love molten salt SMR to be a thing, and they probably will be in some applications in developed countries in 10-20 years, but the value of this to combat climate change is minimal and people who think otherwise are ignoring the previously mentioned facts.
