From https://en.wikipedia.org/wiki/Electric_aircraft :

> [For] large passenger aircraft, an improvement of the energy density by a factor 20 compared to li-ion batteries would be required

The time it takes to surpass this energy density threshold is affected by battery tech investments; which had been comparatively paltry in terms of defense spending. Trillions on batteries would've been a much better investment; with ROI.

Sadly, some folks in defense still can't understand why non-oil investments in battery tech are best for all.

There are multiple electric trainer aircraft with flight times over an hour and quite a few more in development.

Jet engines are terribly inefficient (30-50% efficient) compared to electric motors.
How do you know that simulating reality is the most complex thing software can do?

I'd be VERY interested to see vaccination rates among healthcare workers. I've heard some anecdotes that nurses and even doctors are refusing the vaccine at this point in time. This article says from a survey only a third of nurses would voluntarily take a vaccine, which is a lot lower than I expected.

Religion generally is fragmenting rapidly yes, but I hardly see that as a sign of health. Rather it's a sign that more people are questioning traditional religious beliefs, some of those are latching on to new belief systems, but many are simply disengaging from religion.

I completely agree that magical thinking and conspiracy theory delusions seem to be growing and that's a real problem. I won't quibble about you equating it to religion, it's a valid point.

I think anger is in fashion. And, judging from this article, even hatred (anger without end) may be in fashion too. I'll offer a simple explanation.

The author talks about the connection of anger with memories of past wrongdoings. In my personal experience, it's hard to forget past wrongdoings when the person who did wrong seems like they haven't changed or aren't capable of changing. Then, any restitution seems less meaningful because the harm might very well happen again. In that case, I do agree that a grudge is rational. That's because forgiving and/or forgetting actually might expose you to further harm. However, I don't recall the author really mentioning this take on it. I may be mistaken, but it seemed that their argument was that the simple fact that any wrongdoing occurred to begin with is reason enough to hold a grudge and that this could somehow be considered rational. That doesn't make much sense to me.

That being said, I believe Trump is the reason we're seeing such angry cultural trends. In him, we have a person who has posed a constant psychological (or even not just psychological) threat to maybe as much as half the population of the US over the past four years. He is a man who has done real harm to many people. I also believe many people look at him and see someone who feels no remorse about any of his actions and, indeed, may even seem fundamentally incapable of remorse.

It's completely rational to hold a grudge against a person like that and he has been inescapable for almost half a decade. I think he's been acting as a sort of psychological vortex that's driving everyone towards the angry side of the spectrum. I'm sure the effect has even bled outside the political sphere into other parts of society. In my own life, I've often seen the way in which an unpleasant experience or emotion can sit in the back of my mind and color my perception of everything. I'm sure everyone has experienced something similar.

It's been telling to watch the way in which the world has taken on his pathologies. As much as modern society has chosen to de-emphasize the importance of king-like figures, we humans are still psychologically programmed to take queues from people in positions of power. In that sense, we've all unwittingly become members of one big, broken family with an abusive father.
Given the rich and intricate technical history of Japanese carpentry, it's not surprising that they're the ones pushing this forward. If you search for "Japanse joinery", you'll be in for a mesmerizing treat of intricacy.

I honestly think that what's novel here is the phrasing and a bad twist involving guilt and innocence. Look: the idea that moral corruption can be contagious is not new at all. We are very inclined to mention it explicitly when talking about stories of children surrounded by moral corruption, specially on troubled childhoods. What's somewhat twisted here to me is the idea that this involves any guilt. And the author says it explicitly: if anger or acquiescense are the only possible responses when being faced with injustice (which I don't totally agree with), how can you put guilt on anyone for not being able to escape the inescapable? It just looks twisted to me, trying to impose moral standards in a situation when you know they are not in reach. The only thing that would be immoral here is trying to pass moral judgement in this situation (under the premises the author gives).
I don't have an issue with the approval process itself. But Isreal, for example, expects delivery of enough doses to vaccinate 60% by the end of Q1. They just ordered more. We didn't.

I think you'll cover the people who are clamoring for it pretty quickly. Everyone else will just wait for it to become generally available. I've already had COVID, as has my household, so I'm not in any rush to get vaccinated. Neither are most of the people I know (sample size < 10).
The arguments made against reality being a simulation don't make sense to me.

If the universe is simulation, it will be a huge particle system that simulates every elemental particle and force. Being part of that simulation, we would never be able to prove that a reality exists outside of the system that we exists inside.

If there is a reality beyond the system in which we exist, it wouldn't have to be anything like system we exist in. There is no reason to believe the system we live in is a model of the one it exists inside!?

"In 2021, COVID-19 vaccines will be in all our stores

We’re following federal and state guidelines that prioritize vulnerable populations, including those at long-term care facilities, to be among the first to receive the COVID-19 vaccine.

Once vaccines are available to the general public, anticipated to be in early 2021, we will begin offering them in our nearly 10,000 CVS Pharmacy locations nationwide. We expect to be able to administer as many as 20-25 million shots per month.

When that time comes, booking an appointment for your vaccination will be simple and seamless. The same digital experience that we created for COVID-19 testing and flu vaccinations will be available to schedule COVID-19 vaccinations, so that you can easily book an appointment and, depending on the vaccine type, the required booster dose as well."
Yes I was probably too handwavey about it but that's exactly what I meant.

Once the vulnerable are vaccinated, hospitalization and fatality rates will plummet rapidly. Even if infection rates get far worse hardly anyone (relatively) will die. It will be COVID lite, more like a bad flu season
I am pretty sure that this does not work. Maybe GNU Make accepts folders as targets (but that would be news to me). But even then, the folder itself does not inform you whether your pip install was successful or not.
That's a great effort in technology and it is remarkable. I have some doubt about the real benefits that are beyond the technology though.

First of all about the security of this system. Yes, it is very avantgarde but being a physical support I will always have the worry that it can be damaged.

If I immagine to use it to store sensitive information this worry rise up. It can easily be accessed or stolen or damaged.

And what about the possible cost of a solution like this?

>discussing fuzzy topics like psychology.

Psychology is fuzzy, but the study is quite actually formal in terms of empiricism. You may be thinking about psychotherapy? Not sure, and also not familiar with psychotherapy so take it with a grain of salt.

I'm not invalidating design and all things without rigor. I'm invalidating specific trends where we end up going in circles because of lack of rigor even though it doesn't need to be that way. Software design is one such area.

>I agree with you that design and architecture is a lot about intuition and gut feeling and should be more formal. However, we don't have to time to wait for the formal theory. Foods needs to put on the tables, so income needs to be generated, so business needs to be done, so decisions with incomplete information and lacking formal theory must be made by biased humans. Unfortunately, the complex and wicked problems are usually the more important ones. If you pick C++ instead of Rust, the organization will probably survive anyways. If you pick the wrong technology or person it can kill a company.

Sure agreed, I never said otherwise. I'm more remarking about the evolution of the industry. How much of this decade was an improvement over the previous decade? How much of it was a repetition of the same historical mistakes made again and again? I am proposing that formalism should be used to break out of the loop. I am not proposing that you use formalism to do your job. At least not yet. Think of it as where should the Boss put his funds for R&D? Formalism is it.
How do you know they would be better if they didn't get a Ph.D and stuck in postdoc? It is not like that's the worst they can have. The alternative of failure may be another million possible way of failure.

My apologies. I think I misunderstand what you mean by "ecosystem". All of your requirements are fulfilled by the tools I suggested. The guides I provided show complex typesetting (mathematics and otherwise), eqn does complex math expressions (more powerful than TeX according to Lorinda Cherry, the neateqn implementation by Ali Rudi allows for using TeX bracket syntax as well), pic and grap provide complex (2D) graphics, refer and bib2ref/ref2bib provide bibliography management, and all of it installed from a single repository and makefile (maybe this is different than an installer framework?) to under 43MB (including demos and acm fonts). XeTeX/XeLaTeX seem to only add support for utf8 (as I mentioned, natively supported by the plan9 *roffs) and various font formats (at least supported by neatroff, I haven't checked the others). Of course, pretty PDFs was the original point you quoted in the parent.

You should at least check out the neateqn guide for examples of math typesetting (even output in Computer Modern). But the original guide, as well as the others will show many more and different examples. These aren't groff guides. You might be surprised.
You're describing a feature.

> Differing regulations and standards between countries usually makes no sense and just harms the consumer.

It's true that they don't make much sense and that they often harm the consumer, but I vote in my regional politicians and in theory can vote them out if they impose standards I don't like.

One of the problems with Europe was the perceived lack of democratic control coupled with the dishonesty from anti_EU campaigners about things like straight bananas.
> Meanwhile, Canada lets you import

There are far more important reasons to do this than protectionism and it's disingenuous to skip them and jump straight to protectionism.

Banning old cars would harm the parts of the population which can't afford brand new cars (that's a huge chunk) and guarantees that every time regulation demands something new everyone has to buy a new car.

On the other hand not mandating new safety tech harms everyone in general and guarantees that cars new and old will forever be much worse than they need to be since manufacturers won't be in a hurry to spend more money on tech. Keep in mind that a car with DRL and ABS will be an "old car" a few years from now. 10+ year old cars have ABS today because at some point it was mandated on all new cars.

It's a reasonable compromise to let people buy and use the old cars as they are (or anything that uses old, outdated tech - lead based solder in electronics?) but demand that new ones constantly integrate new tech.

Current LTO-9 tapes can store 18TB and the LTO roadmap doubles capacity about every 3 years. So this tape tech would be on the same scale as we might expect LTO-14 to offer in 2035.

So unless this is an incredibly radical breakthrough, that’s the timeframe I’d expect for the headline to become a real product.

Note that the article shows a table from IBM claiming they achieved 35TB-per-cartridge capacity in 2010, and that still isn’t something you can buy.

Hi anigbrowl, thanks for your thorough review! This is really helpful. I am aware that Tuchu's current strength mostly (and in many cases solely) lies with identifying sentences that summarize, not sentences that explain a concept or convey crucial detail. In that sense the claim of "highlighting the important parts" may indeed be a bit bold.

In my opening post I said that doing your own reading is still a requirement, but it might be good to also mention this on the site — at least until I find a way to improve the algorithm. One way could be leveraging pre-trained word embeddings, but this would require a server or downloading a large blob to the user's device beforehand. In any case Tuchu wouldn't be as fast that way.

Thank you for the informative answer!
That matches what I've found.

I get the most angry when I can't control something, can't wait it out, can't avoid it. Then I feel cornered. "This isn't my fault, I can't escape it, and it's just going to _keep happening to me like it always does_."

As soon as I think of any way to deal with something, or even if someone else says "Yeah this sucks, let's never do this again" I feel relieved.

Like the time I bought some cheese sauce packets, not realizing they had been cut by a box cutter at the store and were leaking. I was angry until I realized I could just take them back to the store and exchange them.

So the hard part is suppressing my anger until a solution appears. I don't know the trick to that yet.

I agree with this completely. I probably think though that the industry needs to be disrupted, ie. prove that you can monetize at scale without relying on user data. I think this is something very hard to change because the industry and its large customers are actually quite conservative. It is understandable because newspapers are not exactly a fast growing sector.

I wish that newspapers at least, etc. would instead consider working out their subscription models a bit more. I like to read stuff from multiple papers but can't justify multiple subscriptions for the occasional thing I want to read from them. The Internet opened new ways for people to access news and information but it just feels like the business model of newspapers hearkens back to pre-Internet times where you would buy the paper either at a newsstand or through home delivery.
This is fantastic, I will share it with students. A very minor comment:

>So, there’s a total of three types of vectors in NumPy: 1D arrays, 2D row vectors, and 2D column vectors.

I think you can have 'vectors' of arbitrarily high dimension, by adding empty axes, or doing, say, .reshape(-1, 1, 1, 1).

I would also tie this point with the rule for broadcasting that dimensions which do not match need to have a value of one. I'm endlessly confused about broadcasting, and find the explicit rule useful.
Thanks for sharing! Are there any good resources describing query planning algorithms (other than the excellent SQLite one that was shared by another comment)?
I'm really not sure where that citation is coming from. It's a Google web answer but the source has no citation. Wikipedia lists a textbook, rather than anything from NCBI, and I'm too lazy to dig further. A corn torilla or slice of bread in the US typically has 1-2 mg of niacin, and a daily recommendation of around 16mg.

3 oz (85 grams) of "Chicken breast, meat only, grilled" contains 10.3 grams of the stuff[1], and average adults get about 30mg/day. Best I can tell this is about nicotinic acid specifically, and might be IV rather than ingestion, which is very much an apples and oranges situation.

Long term US bonds are definitely the most prominent example for the last 40 years. Past 100 years though, not really.

Check the ETF TLT compared to total US stock market, VTI, on https://www.portfoliovisualizer.com/backtest-portfolio or the asset classes on https://www.portfoliovisualizer.com/backtest-asset-class-all...

Their negative correlation zig-zag is remarkable the past few decades. Some research postulates that in a decreasing interest rate environment (past 40 years), they’re negatively correlated, while in a rising rate environment they’re positively correlated, leading to the past 100 years minimal (almost 0) long term correlation.

It's only unwinnable if your definition of winning is to cause more harm to society than the value you create.

Your arms race argument is valid, but I think there's a lot of progress to be made before that negative effect dominates. I don't think we're currently at the optimum equilibrium of regulation vs. evasion. If the punishment for murder causes murderers to evade capture, society matches their efforts; it doesn't just give up.

Israel bet on two vaccines (Moderna and Pfizer), the EU bet on 4. In particular many EU countries (like Austria and others) were hoping for non mRNA vaccines to be approved faster because they would be significantly easier to handle.

We purposefully did not "order more" at the time it was offered since that was before approval. EU countries have been extending their orders after the approval went through to bridge the time until other vaccines become an option.

The EU in total ordered four times as much vaccines as we need.
I delete dotfiles so infrequently (once a year?) that this just isn't a problem for me.
