there is a Programmable Power Supply Mode (PPS) that was added[1] that lets a device dial in exactly what voltage it wants, as the parent comment said, no buck needed (assuming it's within current limit). it made sense to specify. variable output doesn't add much complexity, and it can reduce part count in the exact way we see herr- remove a voltage converter.

on the other hand, just a guess, but I'd guess well under half of supplies (wall & battery) have PPS support. just last month I went out & bought the pro version of the battery back I had been using: same size, same capacity, more expensive but it had PPS, which I wanted to play with (as a hobbyist), and can supply more watts (honestly not that important to me atm).

Yeah you can. You can get something like a CC2531 which works great aswell. Not sure If it's supported by ZHA yet but https://www.zigbee2mqtt.io/ worked very good with my CC2531. I just switched to the Conbee because it was supported by ZHA and I wanted my lights etc to directly connect to Home Assistant with ZHA.

Yes, I remember the 80s, and the USSR was one of those things you just assumed would be around for the foreseeable future, like marijuana prohibition (though for that one there was more of an inkling of possibility given more time). What you can say "within reason" depends on what you think everyone else thinks you can say, so equilibria are both really stable and subject to surprising flips when they finally tip over -- sort of like digital logic.

Drilling down further, it's more about density:

> If you follow the red state trend lines, you can clearly see that any dense, fast-growing cities that emerge in red states will be very likely to vote blue. The few that do already exist already vote blue.

> Red state voters generally prefer low-density housing, prefer to drive cars, and are sensitive to gas prices. Once population density gets to a certain level, behaviors switch: high-density housing is the norm, public transit becomes more common, and gas use (and price sensitivity) drops. Red state values are incompatible with density.

Down to the county level, urban centres tend to have more economic activity:

> A similar analysis for last week’s election shows these trends continuing, albeit with a different political outcome. This time, Biden’s winning base in 477 counties encompasses fully 70% of America’s economic activity, while Trump’s losing base of 2,497 counties represents just 29% of the economy. (Votes are still outstanding in 110 mostly low-output counties, and this piece will be updated as new data is reported.)

Not sure I've seen many (any?) instances of his abusive behavior being celebrated in my 30 years of following him. Certainly some awe over how scary he was.

I've often thought it amazing that he was as successful as he was despite his terrible behavior.

Then again this chart seems to indicate something closer to 2% of confirmed cases are fatal for Covid:

I imagine more non-fatal Covid cases go unreported than fatal ones so perhaps even that's high, but it's still close to an order of magnitude worse than the flu.

Edit:

That first source isn't great, and is outdated anyways. This one seems to verify the ~2% for Covid in the US.

Do they have to be? I remember that a lot of people in the last 50 years or so have been trying to apply permaculture principles on forestry (like the Fukuoka food forest).

As for the carbon stability, the forest renews itself, so if you plant trees in an area where there were none before, the carbon captured the forest itself is pretty permanent. If you want to further capture carbon, you can always cut the trees and use them for timber, and eventually pyrolyse the wood to prevent decomposition and put it in the ground (which can increase soil quality).

Thank you for running those numbers. I hope you don't mind if I quibble with them a little.

Firstly, I tried to fact check your "~49 Gigatons" figure and came up with this quote: "Emissions are currently expected to reach 42.4 gigatons annually in 2020, rise to an estimated 49.4 gigatons per year in 2030" from [0].

Your figure of "$250/Ton of C02 Captured and Sequestered" is probably correct, but it's worth comparing that to this statement: "Table 1 summarizes the projected energy and dollar costs of air capture processes that have appeared in recently published technical analyses. The projected dollar costs are in the range of $100–$200∕tCO2" from a research paper [1] which may not include sequestration costs.

To present an optimistic scenario then, suppose that by 2030 we managed to reduce annual CO2 emissions to 40 gigatons and could capture and sequester CO2 at $100 per ton. That would make the cost $4 trillion per year. For comparison, the IMF projected Gross World Product to be $90 trillion in 2020, according to [2]. We would expect GWP to grow over the course of this decade, so the annual investment starting in 2030 should be less than 4.4%, although I wouldn't like to say what sort of effect that would have on the global economy, even if there were somehow a global agreement to spend that kind of money.

In conclusion, I agree with your assessment, and only ask that you take extra care to use the letter "O" in "CO2" and not the digit "0". It's not so important on a discussion site, but your linked article looks much less convincing due to that typo appearing eight times. (For extra presentational value, you could use a subscript character, i.e. "CO₂").

> I understand what you're saying, but I think there's some "both sides"-ism at play here.

Why do these conversations "always" go like this, even on a site as rational as HN? If we can't even discuss these very real issues here without rhetoric, how do we expect politicians and the masses (and here I include literal deniers) to do so? Because that is what we are asking of them, is it not? To stop being stupid (which they are doing, to a very large degree), and to start being rational?

Also: why is an article as reasonable as this [flagged] (and therefore removed from the public discourse here)? We ask others to stop living in an information bubble, yet are we willing to do so ourselves?

Might this flagging (of which this is but one of who knows how many instances - HN users shall not know such things) hint at some underlying human characteristic that is a root cause of why we cannot have nice things? Obviously speculative, but it seems reasonable to me.
The problem is when “no abuse is acceptable” and at the same time we continue to redefine these types of terms to apply to lesser and lesser offenses.

I don't think we did; there's a bit of selection bias at play for NeXT where they had a large network of stars to choose from and a reputation that would attract a large pool of other people worth choosing. It's just that a lot more people are involved in the industry now so there's a lot more entry-level/ grunt work to be had.

Why is literature illiteracy so acceptable?

There’s two levels of scientific illiteracy. One is in the general population, but the general population also has, for example, literature illiteracy too. The other is the topic of C.P. Snow’s famous Two Cultures essay, where the generally well educated members of society are separated into those who know about science but not the humanities and the opposite. It certainly used to be the case that those educated members of society could discuss both topics. I’ve heard a claim that one thing is the replacement of any kind of ontology for science with mathematics (ie you don’t have a theory for why the world is but merely that some equations hold), and this mathematics isn’t easy—you need a lot more than school mathematics to understand Maxwell’s equations for example.

There are still countries around the world which subsidise fossil fuels. Not indirect subsidies like exporation writeoffs for corporations, but actual incentives for consumers to consume in the form of below-market pricing.

https://www.iea.org/data-and-statistics/charts/value-of-foss...

And even without subsidies, petrol and diesel are undertaxed in almost every country.

Properly taxing fossil fuel is surely a more cost-effective preliminary step compared to schemes like CCS.
What excites me about this approach is that it has the potential to make demos that are also accessible to blind people. It would take some work though, possibly even including support from browsers and screen readers. The pseudo-focus and pseudo-caret features in particular are problematic. Also, blind people might need a playback mode that advances the recording manually frame by frame (only counting frames that actually include changes), rather than playing back in real time.
I am still in awe of NeXT's software technology, generally. It was just so carefully and intentionally designed as a coherent whole; one would hope this was where we were going as we got better at architecting software (as individuals, as a field), but disappointingly in retrospect it appears as a kind of high-point, after which we continued to descend into ball-and-twine mediocrity. For Reasons economic and and social that I think people could argue about a lot, but we don't because in part because as a field we don't seem to even agree on what excellence in software architecture/design even means anymore.

But what I want to talk about instead is:

> Like EOF, our database layer that still puts Ruby-on-Rails to shame.

I spent a couple years programming with EOF (the "Enteprise Object Framework", an ORM), and many more recent years programming with ActiveRecord. EOF had a few features that ActiveRecord still doesn't that I miss (like properly functioning multi-table inheritance; and lazy "eager loading" triggered on first access for all associations; Rails 6.1 has a welcome feature to RAISE on n+1 behavior, but why not just lazily trigger the efficient load instead, which is probably no harder to implement? Maybe nobody thought of it, having not used EOF?).

But I wouldn't actually say it still puts ActiveRecord "to shame". ActiveRecord is very similar to EOF in design, by 2020 nearly as mature, with 80-90% of the features.

Yeah, it's striking that ~20 years later we can say AR is mostly as good as EOF haha (and doesn't have anything of note that EOF didn't already have, it hasnt' superceded it in any ways). It's internal architecture isn't quite as elegant. But it really is nearly as good as EOF, it's deficiencies compared to EOF aren't large enough to be particularly shameful, in my experience/opinion, it's in the ballpark!

AR is so similar to EOF that I have always wondered if some of it's designers had experience with EOF.

Skriber.tv – a service to follow filmmakers and be notified of new releases
Hey everyone!

I love watching movies and tv shows. And I love the possibility to discover new content endlessly, as services like Letterboxd and trakt.tv offer. However, I do find myself browsing IMDb repeatingly, because with my 41 years I have quite a lot of actors, directors, screenwriters etc. who I like to follow and whose releases I don't want to miss. Unfortunately no service offers the functionality to follow actors and filmmakers and be notified, when new releases are announced.

So I hacked a site for myself: skriber.tv

It's quite nice to get an email, that tells me which new movies or shows are announced. But what I almost prefer is the functionality, that the site also lists movies, in which multiple of my favorite actors appear together in. And on top of that, for every actor and filmmaker the site also shows cooperations with other people. It's interesting to see, with which cinematographers certain directors often work together with. This gives me a totally new perspective on discovering new content.

I now received the point, where I could go on implementing new features endlessly, or where I open up the site to a public beta, finally fix some bugs and listen to improvement ideas and feature requests of other users. And I would really love to hear from you!

Kind regards!

starting up an engine isn't nearly as "expensive" as people tend to think. engineering explained did a video on this, concluding that a warm start in a typical four cylinder engine uses about as much fuel as idling the same engine for only ~7 seconds. [0] kinda makes sense, since this is the whole motivation for start/stop systems in the first place.

not covered in the video, but IIRC cold starts use quite a bit more fuel since the engine needs to run rich for a few minutes while it warms up.
