Looking back at history, it would lead to more propaganda and more support for going to war.
A population getting attacked only leads to that population wanting to an us vs them mentality and emotional knee-jerk reactions over rational responses.

Okay that’s good, spaces for hydro storage isn’t an issue.
The only problems/questions left are:
Thus, the expected cost of a 1,000 megawatt pumped hydro energy storage system with a head of 600 m and 14 hours of storage is about $1.8 billion.
1000 MW = 1GW : $1.8B
And your quote says we need 450 GWh of storage.
So 450 x 1.8 = $810B
(I’m assuming I haven’t made a mistake about the 14 hours of storage and the converting between GW and GWh).
Our current GDP is 1.6 trillion.
So we could do it, but it would cost us half of our GDP for one year (but we’d be spreading it out over multiple years).
I’m assuming economies of scale would come into effect, but how much more efficient can you be at making and pouring concrete.
I haven’t found any source on the fiscal cost of the Coalition’s plan (I doubt they even know, and I suspect that they’re just trying to extend the life of coal by relying on delays), but it begs the question:
Would their seven proposed nuclear stations be cheaper than $810 Billion?
Nuclear plants have really really long spin up/down cycles so when it’s on, it’s on for a while. It’s not like solar, gas, wind where you can just stop it on a whim. So if you go nuclear, it’s already running for a long time, and if they’re running for a really long time they’re also essentially running as baseload production.
As for the cost for emergency power, yeah it’d be great if it’s cheaper. But the worse the emergency becomes, the less the cost matters. If I had to choose between coal or nuclear for emergency power, I’d probably choose both. Coal (which can be started and stopped quickly) just to cover the spin up time for the nuclear power, then nuclear for the rest of the emergency (and during spin down as whatever the emergency was is in the process of being resolved).
The cost of nuclear is only at the commissioning and decommissioning of the plant. But during the runtime of the plant is remarkably cheap. People just balk at the initial price because so much of the cost is up front.
Another thing to remember about recycling is that we as a species were producing nuclear waste before we had reactors that could use recycled waste so globally speaking we currently have a surplus of waste. Recently the US had to restart a reactor because they didn’t have enough materials to use for powering deep space probes. It’s not implausible that we could run out of waste to use and have to produce more fresh fuel.
On the topic of safety though, modern reactor designs require power coming in to keep the fissile material frozen to continue the reaction.
As soon as the power is cut, the coolant is cut, part of the plant is destroyed, or something else goes wrong, the plant stops working. If the plant stops working, there’s nothing to cool down the fissile material.
The fissile material’s own radioactivity heats it up to the point that it melts and pours away over what’s essentially a pyramid plinko drain splitting up the liquid into many separate pools. (If it helps, think of your bath’s drain if the pipe splits into two, which split into four, which split into eight, and on and on until a bath tub’s water has been separated into an ice cube tray the size of a tennis court.)
Fissile material only reacts when it’s next to enough fissile material.
And since it’s separated and spread out, there’s more reaction.
If you cut the power for the coolant pumps, the fuel melts, separates (by the power of gravity) and the reaction stops.
If the coolant leaks, the fuel melts, separates and stops reacting.
If you crash a plane into the reactor itself, the cooling mechanisms don’t exist anymore and the fuel melts and pours out the nearest holes (either the drain or spilling outside the reactor into the containment structure, or even outside if need be), spreading out, separating, and reacting no more.
Modern reactors have more in common with an ice-cube hoisted above the great pyramid of giza than they do the fukushima or chernobyl plants. Both of those were designed to require power to prevent a dangerous meltdown which turn into a runaway reactions, whereas modern reactors make it so a meltdown prevents reactions.
That source doesn’t have a link to their paper that works.
But based on what was stated just in your link, they say if we build enough storage then we wouldn’t need any baseload generation, which is technically correct.
In particular, they’re relying on hydro and gas storage.
(specifically renewable gas and not natural gas, because natural gas is still bad)
But as far as I know we can’t build anywhere near enough hydro in Australia. Gas storage could technically work, but you’d have to build a ludicrous and economically infeasible amount of gas storage, or pump it into empty spaces underground (but I don’t think we have enough of those in Australia either).
I’m under the impression that modern nuclear plants as baseload production would still be cheaper than the renewable gas storage we would need to maintain power.
Do you have a working link to the original paper or a study into how much renewable gas storage we’d require and the costs associated with it?
Energy generation is not an issue at all. It’s a completely solved problem.
It’s energy storage that is the problem, and that’s why we need nuclear.
But Dutton isn’t pushing nuclear because he’s being responsible. He’s not actually pushing nuclear, he’s just pushing a pipedream doomed project designed to take time/money/effort away from renewables, storage, and actual nuclear, all to keep money flowing to the coal industry shareholders.
The problem of nuclear waste isn’t actually a problem, and the 1000 year thing is a bit of an outdated myth. I wrote more about it here: https://aussie.zone/post/10867702/9731416
Energy storage is actually the biggest problem in energy right now (save for a crazy discovery like perpetual energy, or cheap mass produced super conductors that could optimize the absolute shit out of our energy transmission infrastructure and reduce the amount of energy that we need to produce in the first place).
The energy storage problem is actually the biggest reason why we need nuclear with our renewables.
Nuclear can run our baseloads, renewables plus storage can run our peakloads.
It’s renewables AND nuclear, not renewables vs nuclear.
Nitpick: Nuclear isn’t obsolete, it’s as modern as the design you choose.
Nuclear isn’t a replacement for renewables (like the coalition tries to suggest), and it isn’t evil (like an internal faction in the greens tries to suggest).
We need:
Sidenote: Since whenever anyone suggests that nuclear isn’t to be abhorred whenever it’s brought up, here are the 3 common things brought up so no one has to ask it.
First, AI is garbage at best, a shield to look busy, move money, and claim benevolence at worst.
Secondly, who is funding the AI?
If I were a company that makes more money the less people cycle or work from home, I’d rename one of my departments the AI consultant department. Then I could pay myself as much as I wanted, be able to spew buzzwords at investors/governments/naysayers, generate nothing of value (as intended), then say to all the governments and cyclists: “Sorry, we spent $X and it looks like putting more gas guzzling cars on the road is still the best solution”.
Better to ask a rubber duck than an LLM.
It has better results, is cheaper, and makes has a positive compounding effect on your own abilities.
This particular release didn’t seem to add much to the core app in terms of features, but it’s nice to see they’re putting work into making the rest of the ecosystem better.
The thing I’m really hoping they fix is the Find / Select feature gap to help power users:
Find & Select support | Find String | Find Regex |
---|---|---|
& Select every match | Supported! | Supported! |
& Select which match | Supported! | No Support |
I made a bug for it: https://github.com/microsoft/vscode/issues/212562
Besides that, and maybe better modal support (for improved vi mode, or alternate modes like kakoune/helix), I’m not really seeing any notable feature gaps anymore, which is great!
Except that there may be better ways to treat mental health issues in the future.
If future generations can revive someone, they’ve probably also cured aging. So for adapting they’ll have all the time in the world, potentially more.
At least it was better than the developer survey that was only about AI. That one still makes me facepalm just thinking about it.
Because: “The dose makes the poison”.
In other words, any chemical—even water and oxygen—can be toxic if too much is ingested or absorbed into the body. The toxicity of a specific substance depends on a variety of factors, including how much of the substance a person is exposed to, how they are exposed, and for how long.
Asking just because I’m curious… why are you using xpath?
Also, is this for a website you control or for some else’s website?
If you’re rendering the page (in a browser, e2e test-runner, spider bot, etc…), have you considered running some js on the page to get the image? Something like: const imagePath = document.getElementById('exampleIdOnElement').style.backgroundImage
The reason I recommend it is because you can’t rely on the CLI itself. Git commands can do weirdly counter-intuitive things depending on the version and settings of your git install. A command that works for one person may not work for another. Or worse, appear to work and fail silently. Or even worse, cause a problem that you won’t find out about until later (if you can even determine the root cause at all).
That’s why I recommended Fork.
Also, it’s not $60, it essentially has an unlimited evaluation period (a la sublime text) so you can try it out for free for as long as you want, and pay if you want too (I have).
The linux port is in progress.
EDIT: just a sidenote, if you really want to force youself to go CLI only, you’ll want to look into how git behaves differently depending on config. I recommend starting with this talk at NDC to get a good enough git config, then move onto Julia Evans blog as she’s currently going on a public journey of untangling how the same commands can do different things in modern git.
You’d probably be better off switching to a more powerful git gui like fork
Shouldn’t you have an adblocker to block those scripts?
No. When he realised he wasn’t immediately given access as he was asking for it he also made a post on the unmoderated reddit board with “Drama” in the title.
He inflamed drama during what should have been an otherwise fairly dull bureaucratic process, tried to hide his earlier posts, was called out on it with a timeline, then eventually half-admitted to creating drama.
Engaging with haters is creating more drama, which makes more disruption, which makes more haters, repeat ad infinitum.
He just needed to ignore them and let the mods do their job, not make their job harder than it already was.
It definitely appeared cordial on his part, but the timelines of events comment showed he was cherrypicking and trying to change things after the fact. He was being deceitful and manipulative which of course made everything worse than it needed to be. He drove away more of the community.
All he needed to do was not be disruptive himself, let the mods sort out the initial haters, and let the boring topic of a commit bit be addressed.
