> College tuition? It's up 2-5X in the past 20 years.

This isn't going to be a popular take, and I have no love lost for Academia (see my post history). But...

College tuition has the same effect as vehicles: they've gotten more expensive over time, but the quality of the product has massively improved from a consumer's perspective.

1. Education: students have way more support now than they did 20 years ago, or especially 40 years ago. It's quite hard to over-state how much more support students are given today. This is especially true at places with higher tuition, such as LACs or elite universities. It's REALLY HARD to not make it through a four year degree these days, and failure modes typically involve some sort of violent crime or substance abuse disorder. And that's true even for canonically hard fields. With a small handful of exceptions, "weeder courses" don't really exist anymore. And even where they do, there's considerable hand-holding.

2. Housing: dorms these days are still way over-priced relative to what you can get in the private market, but quite nice compared to what was available 30+ years ago.

3. Amenities. This is probably the largest. Students have access to world-class gym facilities -- the type that you can't even buy outside of large cities. Rock walls, huge pools, full weight lifting gyms, yoga studios, squash courts, tennis courts, cheap/free fitness classes, etc. all within a 5 minute walk of your bed.

A lot of the increase in the price of college is attributable to the product becoming much "better" -- it's never been easier to get a degree and dorm list has never been more comfortable.

A signal of encouragement, you mean? Like, "invest in this space" -- no pun intended -- "because we'll offer you a great exit"?
It should be noted that typical human conscious notion of 'now' is pretty much a figment of imagination, a strut for reasoning that falls apart when you start looking with sub-second precision. There is speculation, but also a lot of post-process coalescing that mostly hides/reconciles processing delays and time skew of sensory and non-sensory inputs.
Istm that often enough digital activity is inversely correlated with productivity. Some of my most productive days are spent between walking for a bit, staring at a paper, walking some more, staring at code,... Followed next day writing a few lines of code. How will any tool measure that?
> In particular, a school in a valley in the UK having its lights on doesn't on really seem like a big deal as long as they're using LED lights. Attempting to harness natural light in this type of building sounds like a feel-good notion that can't possibly compete with decent led lighting run from a renewable grid.

Maybe that's just me, but natural light is way better for my mental health than artificial light. Being forced to depend on artificial light makes me feel like I'm in a basement, which I don't like at all.
I was under the impressing that the Roche test was an outlier, and that most other tests do not match that. Most other tests have issues with cross reactivity with common cold antibodies.

The Wap, or even the Blackberry, didn’t have an impact on society. It just enabled a few more usecases for the owner but not for the group - like carrying your work with you. The iPhone 2007, and moreso in 2010, was an entire leap forward: It enabled dozens of usecases at a time, such as using Maps, online dating with photos and geographical distance, writing reviews of restaurants… and it triggered efforts in the dumbification of UI, which meant it went widespread like wildfire, which was the condition sine qua none for social media to become relevant. None of that would have been possible with the Blackberry, its wrong commercialization tactics and its 52 buttons.
Well I hope it's not a thoughtcrime to disagree with Orwell slightly, if he actually thought that this is universally true. Language often undergoes simplification and standardization and it isn't always bad.
I clearly remember when I first saw the www, a few years into its life, at a meeting in the Mac users group my dad was a part of, probably at a university department or similar that had internet access.

I thought it was one of the dullest things I'd ever seen anyone do with a computer, and I didn't at all understand what was so interesting about this Netscape programme. I must have been about ten.

I did grow to find it exciting for a few a years, my misspent youth on instant messenger and bulletin boards, learning, flamewars and a few friendships that last to this days... but as I approach 40 and the damn thing has both turned into my full-time job, and become corporate shadow of its old self, something out of a bad old depressing cyperpunk novel, I do sometimes think my initial reaction was closer to the right one.
Small molecule drugs against Covid-19 criticized
We know based on past corornaviruses that natural infection can lead to durable immunity up to 20 years, and like you mentioned with T-cells and more. We also have data showing the current ones so far last as long as we’ve tested them, while vaccines have waned once near a year out. The consensus hasn’t been reached, by my current beliefs strongly tend towards (based on many past similar viruses and all current studies) that vaccine is far less efficacious.

https://www.israelnationalnews.com/News/News.aspx/309762

Note: that’s 6.7 times stronger immunity from natural vs vaccinated! If anything we should have “previously-infected” cards that confer far greater privileges than vaccination cards, if we’re going to be playing that silly game.

Here’s a citation showing stronger T cell immunity from naturally infected: https://science.sciencemag.org/content/372/6549/1418

Natural infection stronger across the board:

Natural immunity holds across even previously known coronavirus variants:

I've used Tesseract.js to recognise the https://** links from the camera input and to make them clickable.

First issue I've encountered was the text recognition performance. Depending on the camera input (if the image contained something that looked like the text or not) I've got 2-20+ seconds per 640x640px image for text recognition on iPhone X. Not so fast as you may see. But the recognition was pretty accurate though.

The performance, as expected, improves when the image size is getting smaller and the amount of text on the image is also smaller.

Since I did't want to recognise the whole text, but only the links, I've used the TensorFlow Object Detection model to quickly find the areas with the text http://**. Then, instead of recognising the whole image I needed to do it only for smaller parts of the image. This gave some improvements to the performance: from the variable 2-20 seconds per frame I've got more stable 0.5-1 seconds. Also not good, but several times faster.

I've described the challenges in more details here https://trekhleb.dev/blog/2020/printed-links-detection/. But to sum up, I had a good recognition quality with an arguable performance with Tesseract.js
LaTeX with PGF/TikZ gave me higher quality typesetting of text,
mathematics, and technical diagrams than other alternatives I
considered. Learning PGF/TikZ made me suffer, but I wouldn't choose
anything else now, especially for complicated or exact diagrams. For a
build tool I used latexmk. The memoir document class easily handled a
full length book. Wrapping text around images was reasonably effective
with the wrapfig package, albeit slightly buggy. I used the Gimp to
remix public domain clipart just for fun illustrations, and Blender
for some crazy looking 3D cover art. If I were better at Blender I
would have used it more extensively. My workflow was limited to a PDF
target because I couldn't imagine any ebook or web format doing
justice to the math, but it did a nice job of embedding hyperlinks
into the document for things like equation numbers and section numbers
that are usable in PDF readers such as evince. As others have
noted, this advice might not be practical if you're working with a
publisher and have to use whatever boring enterprise software the
publisher demands.
-I used to work at a large multinational engineering company which was obsessed by mice - meaningless indicators of company efficiency - for a while, it was decided that we should have large, billboard-like displays at every site showing our progress towards various goals.

> Writers at the FT ponder how to spend their day while equity and commodity markets vacillate listlessly. ...

This is what a lot of people don't get about market bottoms. Nobody cares. It's not like they hate an asset class. They just could not care less.

This is one of the reasons that buying market bottoms is so hard. There's no story. You tell somebody what you did, and they just look at you with a blank stare.

Then you get to wait while ... nothing at all happens. Good news that should turn prices around - nobody cares. Or worse, a surprise snap lower that makes you question your "value" stance.

During the transition period from bear to bull, nobody believes it's real. The bears from the previous cycle who called the top and made the right choice to sell will not believe the bull is real and so will stay on the sidelines. As the market rises, everyone - even the bulls - will expect the inevitable return to baseline. Rinse and repeat. Maybe for years. Not many people will continue to hold on during that period.

Near market tops, of course, it's exactly the opposite. You will be congratulated from here to Timbuktu and back for your "wise" investment when buying into a market shooting higher. You'll look like a star. Somebody who knows what they're doing. There will be lots of talk about new paradigms and how this time it really is different, and why.

You should be selling, but your own brain and the brains of the people around you will make you buy, buy, buy instead.

It's so predictable as to be laughable, except for the pain and chaos that happens when an especially monstrous bull goes to the slaughterhouse.
Regardless of the outcome it will be spun as a success for the executive team, or if positive spin is impossible they will find a scapegoat or other mechanism to downplay their own responsibility.
Yes, that's closer than I thought.

We may well need to deploy configurable sunshade at the earth - sun Lagrange point or something similarly drastic to keep the climate in a hospitable band.
Umm, they are already pretty intimidated. As Starlink stands right now (in beta with partial constellation in service), it's superior to all of those combined. Those guys are shitting their pants right now scrambling to either block SpaceX from moving forward (by whining to authorities) or setup their own competing constellations.
It seems odd to present these tangential measurements when what I think most people are interested in is personal outcomes. How can one relate relative increases in seropositivity to patient outcomes? Why don't we see studies which conclusively nail this down? I'm well aware of this study https://www.cdc.gov/mmwr/volumes/70/wr/pdfs/mm7032e1-H.pdf, I'm unmoved by it, see this comment: https://news.ycombinator.com/item?id=28106987 . Are you aware of more substantial studies to date? Thank you for the links and the discussion. I personally have yet to get the vaccine but do consider myself persuadable.
> vaccines provide a stronger immune response than infection

This is a blatant oversimplification & misrepresentation of the article you referenced, and the paper which it cites [1]. The paper makes no claims that vaccine induced immune responses are more or less superior than the immune response induced by natural infection.

Quote from [1]:

- "Specifically, antibodies elicited by the mRNA vaccine were more focused to the RBD compared to antibodies elicited by an infection, which more often targeted other portions of the spike protein."

Counterintuitively, this property of the current mRNA vaccines - the induction of an immune response highly targeted toward the spike protein RBD - when combined with compulsory mass vaccination, could result in widespread proliferation of vaccine resistant variants [2][3][4][5]. This is a serious concern that is on the radar of many top experts in the field.

The second and third order consequences of mass vaccination using an imperfect vaccine are anything but simple, and very much pose a public health risk.

When you consider the evidence supporting the fact that natural immunity is at least equally effective as vaccination (a few more supporting references here [6][7]), it becomes very difficult to defend the idea you're advocating:

> it's simple enough: pretty much everybody (over 12 until trials complete) should get vaccinated

They won't remember the transition or really realize it happened, but the cultural echoes last a hell of a lot longer than direct memory of the event. Hell, the reverberations of the civil war still echo today.
I stopped being impressed by "one minute in the Internets" a couple of years ago. I mean, internet is at hands distance of many people now.

As beer and toilet paper. Let's move to more significant metrics like people making a living out of it, value transferred or something else :)
Amusing anecdote: The computer that hosted the original WWW is in a little museum at CERN, open to the public. When my family saw it several years ago, it still had a hand written note taped to the side of it, something to the effect of "Please don't turn this computer off."

It still amuses me to think that at one point, the entire WWW depended on someone remembering to not shut it down.

Edit: See below. Reality is much more accurate than my memory. ;-)

The first time I went to a 7/11 in Japan was on my first trip there with my wife (who is Japanese). We got in late and wanted a quick bite to eat... there was a 7/11 next to the hotel and she said "Let's go there!" I scoffed and said that I wanted edible food and she said, just come!

So we went and wow, what a difference from American 7/11's, they actually had fresh fruit and vegetables and the boxed sushi rivals what we can get at our nearby sushi restaurant back home. The rice balls are packaged so the Nori is encased in plastic and stays crispy until you open the package... and the Oden by the register looks unappetizing but is actually quite good. And all very reasonably priced.... and the 7/11's had no problem with our American credit card, unlike many small restaurants that only accept cash... fortunately, the 7/11 also has an ATM that works with most major networks. (some of these no-credit-card restaurants will accept a prepaid stored value card like Passmo or Suica)

We took the food back to the hotel and realized that we forgot to pick up drinks, fortunately, the hotel had a handy beer vending machine on every floor... mmmm...Suntory Premium Malt... even the canned highballs (whiskey+club soda) are good.

We had to cancel our trip to Japan in 2020 due to COVID, and looks like 2021 is out too, hopefully we can return in 2022.

What is the difference? The reason why it is alarming is because there is no political separation. It doesn't really matter which way it goes.

This happened in the 70s. Nixon politicized the role with Burns (who came from the CEA), then Carter appointed Miller (who went onto become Treasury Secretary). And btw, Miller was (with hindsight) one of the worst Fed chairs of all-time.

Tbf, Volcker came from Treasury, Geithner went into Treasury (after FRBNY) but, in both cases, they operated with Presidents who respected the distinction in functions. This distinction weakened significantly under Trump, and is now non-existent.
Great article. I'm curious, did you also post the startup on HN, and if you did, did you do it before or after PH?

Wonder if what they really did was tap employee webcams, then measure the employees attendance that way? Similar to what's done for student attendance measurement in remote classes.

It kind of sounds like it from the description:

Can you conceive of a world, or even just one person, who could say "truth better than falsehood" and actually mean it?

> The other half of the equation is that the more well monied get their message out better than the unmonied.

There's a mixed record on this, really. Yes, massive but subtle spending can result in deep and wide dispersion of a "message". But then there's Rebecca Black and "Friday", too.
As a consumer, I take those '#1 on PH!!' badges as a negative signal, such pride over something so brief and meaningless, displaying it like it's the same as being declared X of the year by some major publication (not that there aren't problems with that too of course).

But obviously some large number of people use PH, and posting there is going to get some eyeballs and sign-ups just like posting on some relevant subreddits will. Just take it off your site, who cares.

The s&p 500 is worse In my opinion. They make it sound like it is the top 500 public companies in the us. Which is not the case. They have group that picks them based on a bunch dumb rules. I like the total stock market index's. If you have people picking what goes into the index they why bother just buy active managed index funds.
"If enough time passes, you can start engaging in the behavior in a healthy way once again."

Spoken like the author has never had someone close with addiction, imo. You'll notice that actual medical professionals never are like "oh just quit your massively health-ruining addiction for several years then you're good to go potentially! Happens all the time, look at these studies." It's because such advice or facts--while technically true in a % of cases--downplay how devastating the next relapse might be for the addict (often it means death, or at the very least, their life ruined). Framing these things to addicts and individuals properly given their situations is very important, but has been totally bypassed by this author "helpfully." They present the article without mentioning their intentions or target audience too, which hardly helps.

"So I dove deep into the topic and looked at what science says about it."

So what credentials if any do they have at evaluating scientific consensus on addiction? Oddly enough the article includes some sources but makes no mention of who the author is from what I can see. Is this some high schooler's opinion after Googling around for an evening? We can't be sure.

"This has some merit, for example, when it comes to alcohol - you can go from being addicted to alcohol, to having a social drink once a week."
"However, that doesn’t mean you need to avoid the behavior forever."

This author needs to like stop repeatedly emphasizing this stuff and muddying the waters--it HIGHLY depends. Again, this is spoken like someone who has never seen someone kill themselves young after that "one last relapse" because they thought they could control it finally. So this article comes off very poorly and I'm disappointed it got upvoted to be honest. Like, the lucky few addicts who recover and can moderate (& their loved ones) probably won't need this article. To the rest of the addicts and people who may be giving them advice, it seems to be a pretty irresponsible article to me.
