SECProto··on Nine US states are teaming up to accelerate the adoption of heat pumps
> phased rollback of net metering in California

Thank you for this clarification - I thought the discussion about changes to net metering was general, not California specific. Reading [1] about the changes to net metering in California, it seems reasonable, especially as it has high solar penetration. Hopefully it will (like many things) lead the way so that load shifting becomes simpler/more economical throughout North America.

SECProto··on Nine US states are teaming up to accelerate the adoption of heat pumps
There are all kinds of complications - commercial solar isn't dispatchable so it does tend to get lower rates than most other sources. In my jurisdiction residential (net metering) customers are only allowed to install a certain numbers of panels - corresponding with household energy consumption and assumed production levels (i.e. your monthly bill will never be negative - at lowest you'll be paying distribution charges and 0 for consumption). With low levels of residential solar installation, locally installed panels can help balance the grid as it is consumed on distribution lines and doesnt need transmission lines (conversely, high levels can unbalance the grid).

> if net metering lets residential solar owners get paid more for the energy they produce than solar farms would be paid, I don't see how that's anything but a subsidy.

Paying them nothing would be even more unfair (and that's the only option available where I am at least - net metering or no household generation)

All electricity generation throughout the US is subsidized in various ways already - eg low interest loans for new generation capacity, programs for low income earners, not (or not effectively) charging for carbon and methane emissions, low fuel taxes on sources used for electricity generation. The "subsidies" you list help make a desirable energy source compete on a more level playing field - matching benefits that competing energy sources already receive.

> There should be standards for EV chargers, so anyone can charge their EV of choice at the charger of their choice.

In north america, essentially everyone has agreed on the NACS [1] (starting in 2025). In Europe they use a "Type 2" aka CCS2[2], and in China they use GB/T[3]. So we're getting there in north america, it'll just be another couple years.

SECProto··on Experiments on a $50 DIY air purifier you can make in 30s
> I mean you can put regulations on anything to make it sure it is doing what it is supposed to be, right?

Yes, and when it comes to selling health-related products, the standards are higher than, say, entertainment devices. For very good reason.

> The harm caused by the lack of a super cheap and effective air filter, especially in CA where we can get smoked out for weeks due to fires could be greater than the harm reduced by the regulation.

That's not clear to me. I know lots of people with air filters, and they all chose them based on aesthetic judgements. I doubt any of them would've acted differently if it was $5 cheaper (from certification)

Also, you can still just buy a box fan ($30) and tape a filter ($10) to it and hope for the best in terms of air purification. You just can't pay someone else $70 to sell you that, unless they run a test to prove it works. Doesn't seem like a big deal.

SECProto··on Experiments on a $50 DIY air purifier you can make in 30s
Reading [1] about the regulations, it sounds like the only requirement (for self contained air cleaners) is that it has to be certified, and can't produce ozone. That seems pretty painless, and I would like the comfort of knowing that if I buy an air cleaner, it actually does what it says. Same as masks should have testing requirements to show efficacy.

The USSR peaked at nearly 40,000 nuclear weapons, one for every 10,000 people in the US with 15,000 to spare for allies.

What makes you say that? It looks like a JAXA programme to me:

SECProto··on Can ultraviolet lightbulbs end the next pandemic before it starts?
> The far UV spectrum being talked about here is not the same as conventional UVC germicidal lamps, nor the same as UVA/B from the sun.

I was responding to someone suggesting outside-levels of UV exposure. If we're talking about a different wavelength, I am even more doubtful of the safety.

SECProto··on Can ultraviolet lightbulbs end the next pandemic before it starts?
> I suspect that subjecting people indoors to an amount of UV radiation comparable with a day outside might be OK

And I suspect this is very incorrect. UV is beneficial at low quantities, but has serious negative impacts on human health at high quantities.[1] Your mention of using it in common areas (where individuals would only be for a few minutes a day) seems much more reasonable.

SECProto··on Japan's Comfort Food: The Onigiri
Yup, if you want to do it at home, make it a little bit mushier. I don't like it, but it is very doable. Commercially they may use a binder, I don't know, I just wanted to make sure people knew they're available!
SECProto··on Japan's Comfort Food: The Onigiri
The amylopectin details may be right, but the rest is wrong. Conbini's sell brown rice onigiri (look for 玄米), it's just usually a very limited selection. They don't fall apart, and you eat them the same as normal onigiri.

SpaceX didn't apply for 25/3, they applied for 100/20. The rest of your comment matches my experience.

SECProto··on Firefox Keeps Getting Faster
Thanks for the advice - hopefully it helps others. For me, it happens infrequently enough that I am unlikely to remember anything specific for the situation. I never select multiple tabs otherwise.
SECProto··on Firefox Keeps Getting Faster
> except for waiting for every page to reload.

When I lose firefox (usually when power outage) I just cycle through all the tabs with ctrl+tab, by the time I get back to the first one it has reloaded (and the others do so in the background). It's not a big deal.

SECProto··on Firefox Keeps Getting Faster
> This might be a Windows issue rather than a Firefox issue

I leave multiple tabs open for weeks+ on Windows (and android), I have never experienced any issue (except when windows decides to update - but firefox always restores itself without issue, or I can press ctrl+shift+t to reopen previous tab/session). There must be something specific to the other commenter's setup, whether it be specific addons or specific pages that are causing the crash.

Amsterdam is roughly 25km across, so less than an hour on surface streets (which this is about). Meanwhile, Austin Tx is a similar population, roughly 30 miles across, and takes ~50 minutes to drive across if you avoid the freeway. They're pretty much identical (but Amsterdam's streets will be much safer for everyone)

> If the grocery store wanted to charge me 10 cents per visit for the air I breathe, I would have fundamental issues with that, but I'd still probably pay.

Really? You'd just pay it? (maybe negotiate them down to 6 cents like google did then pay it?) I'd probably just stop going to that grocery store (eg like meta no longer serving Canadian media)

SECProto··on Canadian government reaches deal with Google on Online News Act
> As a Canadian this is disappointing to me. I disagree with the law.

As a Canadian, this is exciting to me. I agree strongly with the goals of the law (while holding nitpicks about the actual wording). I think the fact that Google came to an agreement shows that they don't have a fundamental issue with the law either (or they could've just withdrawn from our market, like Meta). It's a win for independent media in Canada, and thereby, for all Canadians.

SECProto··on Starship lunar lander missions to require nearly 20 launches, NASA says
This is the answer. Apollo missions were essentially 6 stages (3 to orbit then TLI, lunar descent stage, lunar ascent stage, CSM). Maybe 7 if you count dropping the service module for reentry.

The whole concept of starship only works if they can launch reliably a couple times a day

The point of my comparison with a local developer is that you're hearing one person's viewpoint, who has a very specific interest in the case - so you hear the one specific worst piece of the review process. That criticism is valid. But if you heard only the other side, you'll hear about unsafe development process launching a rocket with inadequate protection of the flight termination system, resulting in extremely dangerous delay between destruct command and ignition of the device. Both viewpoints have validity. The truth is somewhere in between.
