ZeroGravitas··on Slovenia becomes first EU country to introduce fuel rationing
Partly, though both have had periods of right wing governments trying to make this problem worse to benefit their oil and gas industry backers.

And now the same people are saying that the answer is more oil and gas.

ZeroGravitas··on Slovenia becomes first EU country to introduce fuel rationing
Sounds like a good plan unless we've invented 2 much cheaper and faster to deploy methods to generate electricity.

Did you read the comment you replied to?

> This is, on the high end, 20% of the use of fossil fuels. We overwhelmingly burn oil and gas. If we displaced the burning, Hormuz would not matter (or would minimally matter for a few molecules) and the world would be awash in abundant supplies.

ZeroGravitas··on Olympic Committee bars transgender athletes from women’s events
And those outliers are much more likely to be women born with Differences in Sex Development than trans. Like over 100x more likely.

They're rare in everyday life, but this process selects for them.

And then they get attacked and misrepresented by people who claim they are protecting women.

ZeroGravitas··on Rising Air-Conditioning Use Intensifies Global Warming
Peak hours after you subtract all the non utility solar.

The peak grid demand has slowly been moving later in the day (and year) because home and commerical and industrial solar is displacing grid demand.

People regularly use this solar success to claim solar is useless.

ZeroGravitas··on Ask HN: Best way to track medications for elderly family member?
There are services that put the weekly pill regime into a custom blister pack with morning, noon and night so you can keep track of what's been taken and what's not.

"Medication adherence packaging systems" appears to be a term of art for them.

ZeroGravitas··on ‘Energy independence feels practical’: Europeans building mini solar farms
It's not a buyer, people are paid to take the energy that would otherwise be wasted. And when energy use is shifted it means you need to generate less later, saving money.

The people who pay that cost to the people using the energy are people running energy generators that suffer wear and tear when they ramp down.

Or sometimes it's a subsidy for the use of clean energy being passed on to ensure the clean energy is actually used, not wasted.

All upside, no problems at all.

ZeroGravitas··on AI got the blame for the Iran school bombing. The truth is more worrying
The House of Saud put out an interesting think piece suggesting the whole war might be a result of AI psychosis.

The submission here is flagged dead though.

ZeroGravitas··on ‘Energy independence feels practical’: Europeans building mini solar farms
Yes, but even more so, it's a good sensible rule!

People don't even bother to argue why it's bad, they've just seen so many headlines telling them it's bad they don't question it.

ZeroGravitas··on ‘Energy independence feels practical’: Europeans building mini solar farms
Are you talking about rooftop solar?

For an 800W balcony system your background house usage is likely to be enough to self consume most of it.

You'd wouldn't be able to run even a small oil heater except maybe in peak summer.

It's a good match for working from home as it's a small amount of power spread over daylight hours.

ZeroGravitas··on ‘Energy independence feels practical’: Europeans building mini solar farms
US costs for rooftop solar (at build time or retrofit) are misleadingly high.

In the EU build time solar roofs overlaps with utility costs but up to 1.5x , and retrofit is say 2x.

To give context. In the EU adding solar to new homes is cost competitive with running existing(!) nuclear plants. In the US only utility scale is competitive with that.

Retrofit rooftop solar is about the same as new nuclear in the US, retrofit is 25% cheaper than new nuclear in the EU.

ZeroGravitas··on ‘Energy independence feels practical’: Europeans building mini solar farms
He also removed the effective ban on onshore wind construction that was introduced a month after he lost the election, restarting after a decade of lost opportunity.

This Trump-level idiocy that is just never mentioned, even as people blame the gas burned in england on windy days as a cost of wind curtailment, when the curtailment is more a like a third of the cost. Burning gas to power people who chose not to build turbines is the other 2/3rds.

In the alternate world that is tens of billions of gas costs avoided to date and tens of billions more in future.

ZeroGravitas··on Show HN: I got tired of biased (all) news so I made Claude cosplay each side
It's not an AI issue, there's human based fact checks that similarly "confirm" as "true" the non-interesting bit of a claim.

Snopes has a "Correct attribution" label for this, which also covers ambiguous jokes, misstatements etc.

ZeroGravitas··on Iran oil revenue soars as it's the only exporter out of Hormuz
You can do solar -> hydrolysis -> hydrogen -> ammonia-> fertilizer, rather than methane -> steam reforming -> hydrogen -> ammonia -> fertilizer.

So it's technically feasible. Not quite there in terms of cost and scale but if the alternative is a blockade then probably worth investing in.

Ironically some of the best locations for production are in the middle east.

ZeroGravitas··on Show HN: I got tired of biased (all) news so I made Claude cosplay each side
Writing CONFIRMED after a lie said by Trump because you've confirmed that Fox News claims he actually said the lie isn't a great UI.
ZeroGravitas··on Shell Tricks That Make Life Easier (and Save Your Sanity)
Also worth reading the intro to fzf search syntax.

https://junegunn.github.io/fzf/search-syntax.

The $ and bang and exact search are neat, but the bit at the bottom as to why `gadd` or `gas` is a better search for `git add something` than something with full words and spaces is a revelation when first using fzf.

ZeroGravitas··on Sodium-ion EV battery breakthrough delivers 11-min charging and 450 km range
Elon is a fraud but Jeff Dahn and Dalhousie are legit.

Lithium batteries have been increasing in density at about twice that rate for the last decade. And million mile LFP batteries are available, NCM is nearing that benchmark.

All credit to the people who actually research and build them which is not Elon, since Tesla don't even produce the majority of their own battery usage.

ZeroGravitas··on Seven New Towns Planned for England
I wonder if they plan to avoid connecting them to the gas grid from the start.
ZeroGravitas··on Shell Tricks That Make Life Easier (and Save Your Sanity)
Vi mode is also available in Claude code and gemini-cli to give some recent examples, and a bunch of other places you might not expect it, as well the more obvious places where code is written.

Once you get used to it, it is painful to go back.

ZeroGravitas··on Do Back-to-Back Courtroom Losses Herald Meta's 'Big Tobacco' Moment?
"Big Tobacco moment" meaning continuing to make billions by ruining the lives of kids in poorer nations long after richer nations have protected themselves somewhat from the threat?

Well paid sociopaths plotting every day to stop governments from doing the basic job of protecting their people from predatory foreign businesses?

Those same deeply damaged people using their ill gotten gains to fund reactionary politicians at home in hope that they can further exploit their home population if they can distract the people with fake culture wars and real actual wars?

ZeroGravitas··on Iran rejects US proposal, lays out five conditions for ending war
Some thankless government employee is trying to talk Trump out of commiting this series of war crimes right as we speak.

I wonder if Iran forsaw that. They've been doing the tit-for-tat thing pretty well so far. What kind of mass scale civilian casualty war crimes could they retaliate with?

ZeroGravitas··on Apple Can Create Smaller On-Device AI Models from Google's Gemini
Does it make sense for a single model to be used for all on device LLM tasks or for each app to provide its own customized one?

My gut feel is the former but not sure if that's actually true.

ZeroGravitas··on UK total wind generation record beaten today
Apparently they've announced some plan to sell this power cheaply to local people on the same side of the bottleneck, though I've not seen the details yet.

Seems to be another one of those sensible ideas that needs a global crisis to be pushed through to reality.

ZeroGravitas··on War in Iran exposes US's shift from a global guardian to an arbiter of chaos
It's that a new meaning of arbiter?

Judge/witness doesn't seem to fit.

ZeroGravitas··on AI for nuclear energy: Powering an intelligent, resilient future
Finally, we can combine the two classic joke thought experiments of "imagine a nuclear power plant running on windows" with "imagine a nuclear power plant run by AI".

I still don't get the obsession with nuclear. I assume at some point the military takes you aside and promises you secret billions if you keep their military supply chain intact, and all the weird online fanboys are downstream of that.

ZeroGravitas··on Mystery jump in oil trading ahead of Trump post draws scrutiny
A massive failure could blunt or slow their attempts to seize Cuba, Greenland and Canada.

On the other hand an inadvertant success, like Venezuela, could accelerate those plans.

ZeroGravitas··on Miscellanea: The War in Iran
The failed revolution a month prior may have been the US too.

It's after the ramp up in production of weapons used in the shooting war started.

ZeroGravitas··on Cuba's Fragile Power Grid Finds a Powerful New Partner
It would be interesting to read an actual deep technical dive on this.

Was cuba previously generating electricity with imported oil? How were they paying for that? A gift from Venezuela? It seems possible that the solar is actually batter and cheaper than what they were paying for before but needs up-front financing, which is a general issue with solar in developing nations.

ZeroGravitas··on Iran war energy crisis is a renewable energy wake-up call
Portugal is at the cheap end of EU prices. Of the ones lower several are just directly setting the price low by government fiat or subsidy.

Countries that have genuinely lower prices either built nuclear 40 years ago, or have great access to hydro they built 40 years ago or a bit of both.

Wanting to build nuclear now for cheap prices doesn't make any sense. It has the same high up front investment shape as renewables, except higher costs.

ZeroGravitas··on Learnings from training a font recognition model from scratch
Surely the next step is to tweak the open source font with AI to slightly better target the desired font?

Sometimes you're trying to replicate a logo and they've hand tweaked a letter or two, or stretched it.

edit: (Google Fonts actually have fonts you can natively stretch and some with replacement character variants) I wonder if the tool uses that to better match?)

Sometimes you just don't want to pay for a fancy font and I believe font shapes are not copyrightable?
