SV Delos has a great video on power generation methods https://www.youtube.com/watch?v=Osh1ljtgnSU . It is a larger boat (58ft?) that is lived on full time and they use a combination of solar, wind and fossil fuel for energy.

In another video (can't find it offhand) they talk about propeller driven generation and how it isn't a great solution for them. Propeller driven generation is expensive, it requires another hole in the bottom of the boat, requires maintenance (marine growth), it only works when the boat is moving, and its power ultimately comes from the wind or fossil fuels. Why not get the energy from the wind directly using a wind generator? It's cheap, effectively maintenance free, runs whenever the wind blows even at anchor, and if you're running the engines, more efficient to generate electricity using the generator. They have the wind generators mounted above and slightly off the back of the boat, where they are out of the way and remain permanently.

They mention their energy generation mix is about 10% wind, 25% fossil, and the rest solar, using 3 panels. Their numbers were generated in low latitudes where solar insolation is quite high, so kind of the sweet spot for solar. I imagine further north wind generation is comparatively more useful. I know more recently they have added some flexible panels on the canopy which added a bit more capacity.

I'm guessing that Peltier generation is not going to be effective for anything more than fractions of a watt. The studies I see online all work with larger temperature differentials, like > 50 deg C, which you aren't going to find anything close to in a thermocline layer. To work with a smaller temperature differential you would need to increase surface area immensely, and water is a high-drag environment.

I found it interesting that one of the more power-hungry things on a sailboat is fresh water. Watermakers consume 15-30 Wh of energy per gallon, and a boat will need about 20 gallons per day per person. For a 4 person boat, that 80 gallons requires 80*15=1200Wh each day. Most sailboats will use the generator to fill up the freshwater tank because they don't have enough solar capacity.

Very cool! Also I’d hope to see Lyme in the mix. It’s so pervasive and creates all kinds of weird dietary and nervous system issues.
I did a ctrl+F for the word "redox" here, since that's already modern experimental OS being written in Rust that's existed for some time, and I was surprised not to see it mentioned at all; I figured there would be a section for modern OS neophytes like me comparing and constrasting the two. Anyone have any insight into how this project differs from Redox?

Wow, so increasingly illiberal Poland is now importing American notions of free speech in an act of right-wing solidarity or something?

I've seen a clever mathematical trick that derives the Schrodinger equation out of GR. As you know, there's this invariant interval thing: ds2 = c2 dt2 - dx2 - dy2 - dz2. The trick was to add a small oscillation multiplier to ds2, so it would become ds2 exp(a cos wt) = ... Mixed with lorentz transforms, this yields the static SE and mixed with GR tensors stuff this yields the time dependent SE. I can't judge if this trick is physically sound.

I didn’t downvote, but I am wondering if this happened. A quick search of NPR transcripts makes me think the last time the mismatch hypothesis was discussed on All Things Considered was in 2012 and it was actually taken seriously (it was the focus of the piece). Perhaps you are thinking of a different public radio show, and inadvertently proving my point that people are unable to differentiate NPR news with other stuff they hear on the radio.

I don’t think experts are reading tea leaves and it’s pretty wild to claim that. There are literally billions of dollars at stake. To bring it bag to software, that’s like me claiming I think machine learning people are just using fancy excel formulas.
It's not often I get to say that I think you're genuinely wrong, but here I think you're really far off the mark. Goldwater flipped the deep south (GA SC AL MS and LA). Nixon noticed and ran the same strategy in '68, by which point the entire south, wall-to-wall, was lined up behind the southern strategy (the states that didn't go for Nixon went for Wallace). I don't see any way you can read the history of the 1960s and 1970s as the Republican party running away from segregation; the opposite is true, and was literally recorded in newspaper features of the time:

https://www.nytimes.com/packages/html/books/phillips-souther...

(Similarly, I think you've collapsed the GOP of the 60s too far down; the Rockefeller Republicans were, on domestic policy, square in the middle of where the mainstream Democratic party is today. George Romney would have opposed AOC, but so does Gina Raimondo.)

At any rate, when people debate which is the "racist" party, they almost invariably ignore the fact that the US was a 4-party polity in the mid-century, not a 2-party polity. What's changed since then is that we have, from 1980 through today, sorted down to 2.

Yeah I agree - so much of the original downlplaying of Covid was along the lines of "Well, the flu kills 50,000 people per year and we don't take extraordinary measures" which is an insane line of thought for multiple reasons but not least because we just write off 50,000+ people per year without much of a stink.
The pfizer vaccine looks to be sitting closer to 30%[1] than 95% based on the parts of their trial data they are choosing to release.

>With 20 times more suspected than confirmed cases, this category of disease cannot be ignored simply because there was no positive PCR test result. Indeed this makes it all the more urgent to understand. A rough estimate of vaccine efficacy against developing covid-19 symptoms, with or without a positive PCR test result, would be a relative risk reduction of 19% (see footnote)—far below the 50% effectiveness threshold for authorization set by regulators.

Option Volatility and Pricing by Natenberg is extremely complete while managing to avoid drowning in maths, it is widely recommended and considered a classic. There are more informal books around that focus a little too much on trading/application rather than mechanics, and an endless supply of textbooks that'll either bore you to death, drown you in maths or both.
I'm not sure it's fair to fault the Unifi software for using a self-signed SSL certificate. I think the only theoretical security risk here would be that Ubiquiti could decrypt the traffic between you and your Unifi controller, if they could somehow obtain it. (Someone please correct me if I'm wrong.)
Ultimately, if you don't trust the certificate it comes with, it's not too difficult to replace it with one of your own (in fact, the page you linked explains how).

I hate tmux because the way it handles switching windows is terrible. The model is switching between windows, each of which can have some layout of panes. This is approximately never what I want for a long-running thing I can detach from and reattach to, from a different terminal with different connections. Further, it supports multiple attachments by each having them see the same exact thing. For terminals that are different sizes, it shoves everything into an area the minimum height and width of all attached clients, and displays everything outside that as a field of periods.

I really prefer screen's functionality, instead.
Each pane can be independently switched to any of the pool of underlying ptys being managed.
The exact layout of panes is more of an ephemeral thing. On wide terminals I can split side-by-side, on narrow ones I can split top-above-bottom (and these can even be different for different clients connected to the server). It handles the multiple attached clients by only make

I think tmux's model is due to being too closely modeled on GUI virtual desktops.

That rant aside, tmux does have some nice features available by default that take a fair bit of configuration to get working well in screen.
Unnecessary. If Facebook and Twitter wish to donate their monopoly market share to Alt-Tech, let them. They've already promoted the Trump effect via conservative info virality for years; the logical next step is to make conservatives completely stop listening to the center and left.

"No one can censor you if they don't know what you're saying"
Is this another way of saying "All models are wrong, but some are useful."

Us mathematically, and computer inclined people like to think math has a sort of universal truth to it. But it only has truth within the bounds of it's own system, or it would break one of Godel's incompletness theorems, right?

As I write this, I'm kind of thinking that the "All models are wrong" George Box quote is almost a statement of Godel's theorem.

And that's bullshit. Mueller Report was a damning document that Mueller didn't have the guts to force Barr's hand, and Barr gleefully lied about and declined prosecution.

Furthermore, the objections by many about the election being "hijacked" was not an actual claim to voter-box or voter fraud, but of disinformation and foreign interference.

I definitely think we need a better solution for moderating social media

I don't think the answer is "everything that's legal"

Laws aren't light enough weight to make some determinations. Eg I think it's reasonable to ban posts that incite violence after people literally storm a government building, and I don't expect most (non authoritarian) governments will react quickly enough to do anything meaningful.

However, we need better, more transparent systems (especially in the US) of deciding what should or shouldn't be allowed

(Note: I actually think that changing algorithms to make it so that people aren't encouraged to see conspiracy theories is much better than censoring them outright. And so I think there is interesting space for innovation there.)

I fully agree, though, that it's incredibly concerning to have 3 (or fewer) unelected people deciding what shouldn't be read or seen
This is how stores are in the real world - suppliers pay for good shelf space and for things like endcap displays. Also, salespeople get a bonus for selling particular items.

What about my PeerTube instance hosted on a NUC in my kitchen? It hosts copies of videos and comments from other instances.
The question is, can this capitalistic economy function without mass consumption?

The development of the middle class was the best thing to happen for American capitalism. A billionaire won’t buy 5,000 pairs of jeans, but 500 middle class households would. Capitalism, as we know it doesn’t exist without a middle class buying goods and services at scale.

What happens when the purchasing power of these households is curtailed and the middle class shrinks? What are the long-term effects on the sustainability of a vibrant economy?
If an ISP is NAT'ing everyone (which I've heard of referred to as an "InterNAT Service Provider"), does "bridge mode" mean you get a real public IP? How does that work with everyone else still behind the NAT?

(I have an actual end-to-end-connectable public IP from my ISP, which from the general discussion seems like an increasingly rare thing --- they keep pestering me to "upgrade" to outrageously faster yet slightly cheaper plans with a "free router included", so I suspect they are trying to get me to give up that IP...)

Targeted advertising seems to benefit everyone compared to untargeted advertising?

My google ads are mostly saas software and tech gadgets, which I prefer over random ads.

If a lip gloss company wanted to advertise, is it not better that they can target people who like lip gloss instead of a random audience?
They're everywhere already - but just like them being not popular enough for spammers to notice them, they're not popular enough for you to notice them either.
From an economic perspective there's a relatively simple solution: requiring experts to wager a certain amount of their own money on a measurable outcome of their prediction when making public policy recommendations. If somebody's not confident enough in their own prediction to put their own money on it, then that prediction shouldn't be used as the basis for policies that can affect millions of peoples' lives.

I'd like that, but consumers seem to like things being "all in one place" - mostly people who are pretty dedicated to niches these days are willing to go to other social sites, but I can't imagine that the mass market will become OK with having like 10 different portals with inconsistent user experiences, unless under some kind of umbrella - be that a centralized service like Reddit or something else.
Redox is a unix style operating system with a unix style design and ABI.

This operating system shares none of those goals, it seems to focus on a particular challenge related to the abstraction between subsystems of the operating system, following a term they call "state spilling". The goal appears to be to design an architecture that supports in-place updates of most components due to them having tightly constrained state management and inter-component dependencies.

"Are experts real?"

Yes. They are also sometimes wrong.

Also sometimes a person fakes expertise.

Also sometimes an outsider to a field makes a useful discovery or insight the experts missed.

None of the above preclude the existence of actual experts.
The primary thing I disagree with here is the thought that we can squelch our way to a more informed public. You clearly believe you can discern truth from lies, as do I. So why should the solution to misinformation be to trust a small group (who we didn't elect) to parse truth from fiction? I'd rather have access to all the information, and be better at discernment. And I reject the idea that we represent a minority of the United States. I think most people are way better at detecting lies than we give them credit for. The problem is, both sides lie. So it's too easy for us to view those who hold opposing views as ignorant fools, because they are on the side of a lie, regardless of if they believe that falsehood or not.
