By far the greatest educational piece I've come across on this subject matter.

Did active investors do significantly better, or did they just benefit over the short term from massive government efforts like everyone else? The real test of the market will be if Biden wins and all of the Republican “deficit hawks” wake from the coma they’ve been in for the last 4 years.

I would say it’s far too early to draw conclusions about the pandemic stock market, and certainly to say that an observation which has generally been supported by data for the last century or so is no longer valid.
Is there an internet meme (equivalent to a Godwin's law) about "back-doors 'coz of terrists-n-kiddiepron"? I was expecting for it to feature in the article and sure enough there it was.

The narrative that "bad people use X" becomes "bad people used X to do thing Y and the government was helpless to stop it, omg!" in various echo chambers. Soon, news reports start appearing with "Thing X was used by bad person. If only the government could have acted in time, tragedy would have been averted".

The various governments and TLA's arguing about the need for back-doors is akin to them complaining that they can't solve crime because of the invention and use of curtains on windows. I mean, can you picture them arguing that if only people left their curtains wide open all the time then there would be no more crime happening inside houses.
"Kitchen knives" went too far to be an example. How about door locks?

I still don't get the idea that having a weakened security system could somehow benefit security. Based on many real-life hack stories I've heard, it's usually the "bad actors" who's taking advantage of unsecured apps to attack normal people, this is the very reason why developers are making apps more secure to begin with.

Another point is, insecured systems are usually easy to take control of (By injecting malwares payload into the brokenly-encrypted traffic for example), then "bad actors" can turn those systems to a trojan proxy. How does that help if you want to make things safe?

Last point: I know this is about big companies encryptions. But really, "Roll Your Own Encryption" is not that bad anymore if all other "secured-encryption" was bugged. And, really, roll your own encryption is not that hard today if your only goal is to annoy the FBI.

Real last point: Even if companies such as Google and Facebook did banned encryption, does that also prevents "bad actors" from using real encryption on top of their service? You can even send your nudes to me safely by encrypting it with my public key and publish the encrypted data here (Don't actually do that). The point is, even if you've successfully banned encryption in big companies, users will then just add a layer of encryption of their own, and that layer can be very very secure.
These are nice but I suspect these accounts suffer from survivorship bias.
Reading point 1, I feel like I am being legitimately gaslighted. Tech addiction is so very obviously present in myself and in many people I know.

Are they saying that it’s a myth, just because it hasn’t been rigorously studied yet?

Why does the QR code need to be scanned from an iPad? In Singapore's now mandatory and hence ubiquitous SafeEntry system, the check-in QR codes are simply printed out and pasted near the entrance.

Also, the <title> tag is blank, which looks rather unappealing since you get a raw URL in browser tab instead.
Not everyone can hear it (like my wife) and if you live on the water, it's pretty obvious it's the boats. It's when you don't live near water and you hear it at 2am, and go "wow, that's really interesting," and then go to sleep.

I literally haven't thought much of it until reading this article, other than passing observations. For example, I've noticed it's not audible in every house, and usually not audible on the ground floor when it is audible on other floors.
Are you talking about the footer? A very small percentage of people would scroll all the way to the bottom especially on a relatively long page like this (5583px tall on desktop). Speaking of actually visible branding, there's a DuckDuckGo logo (without wordmark) in the top left corner and that's about it. To most people who aren't familiar with the DuckDuckGo logo, this would indeed look like the site of some privacy advocacy group.

Edit: Didn't notice that the sticky header once you scroll down does say "DuckDuckGo Blog". Not sure why it can't just say that in the actual header; intentionally vague or baffling design?
If you get lucky gains starting out doing riskier things like WSB does, you might be more inclined to keep that style until you take some losses. And if you're swept up in WSB's fun, you'll probably end up taking more losses. WSB is basically an accelerant for investing psychology.

So perhaps I own a factory or two in the Republic of Elsewhere. I think it prudent to get one of my kids over to the USA. I call up a tech company in the US and make the following offer: you hire my kid, I'll pay the salary and enough over that to hire somebody to do that job, and a generous sweetener above that.

In practice, I suppose somebody with that kind of money has other options. Still the proposal seems open to abuse.
TL;DR: For gaming, because ‘input lag’.

[In a CRT] the electron-to-photon exchange happens instantly. While CRTs do have some sources of lag —namely, the time spent buffering each video frame and scanning each line of the frame from top to bottom on the screen —those delays are on the order of microseconds. When you move your mouse or press a button on the keyboard, the response time is imperceptible...

By contrast, an LCD requires physical movement on the part of every pixel. On an LCD, the back of the display emits a constant stream of white light, which passes through a polarizer and onto an array of liquid crystals. Applying voltage to each crystal causes them to twist, altering the amount of light that comes through the screen's front polarizer.

Compared to electron-photon conversion, the physical movement of liquid crystals inside an LCD display takes a lot more time, introducing input lag. It also creates blurriness when there's a lot of motion happening across the screen.

Also TL;DR: CRTs to look for.

Sony FW900 16:10 CRT [also sold as] HP A7217A, SGI GDM-FW9011, and Sun GDM-FW9010 ... 16:9 CRT monitors including the Intergraph InterView 28HD96 and 24HD96... [and] you'll need a graphics card with an analog output, such as Nvidia's 900 series and AMD's 300 series cards, or a digital-to-analog converter.

Sure, but what does that have to do with the pandemic or the current state of the economy? It will always be true that active investors are more likely to get "lucky" gains than passive investors. The allure of gambling isn't going to suddenly go away once the overall economy stabilizes.
Ask HN: What's your favorite “forgotten” technology / software?
Recently read about Oberon system and its compile speed, simplicity etc..

Finding out more about not-so-mainstream tech is one of the main reasons I read HN. And I see once in a while some "forgotten" tech mentioned, from where it seems the current state of art is a step back.

What's your favourite software / technology / tools that were better but couldn't make into mainstream?
There's a hierarchy of needs. Segment and a lot of related services are geared towards data collection and instrumentation. That part is relatively easy and has a very mature market. The actual valuable part is to gain actionable insights and that remains stubbornly difficult. From what I've seen, it's the kind of work that still requires an experienced marketer with good instincts.
And set a favicon too.
"If you were dropped at a random point in America today, nearly all the food around you would be bad for you. Humans were not designed to eat white flour, refined sugar, high fructose corn syrup, and hydrogenated vegetable oil. And yet if you analyzed the contents of the average grocery store you'd probably find these four ingredients accounted for most of the calories. "Normal" food is terribly bad for you. The only people who eat what humans were actually designed to eat are a few Birkenstock-wearing weirdos in Berkeley.

If "normal" food is so bad for us, why is it so common? There are two main reasons. One is that it has more immediate appeal. You may feel lousy an hour after eating that pizza, but eating the first couple bites feels great. The other is economies of scale. Producing junk food scales; producing fresh vegetables doesn't. Which means (a) junk food can be very cheap, and (b) it's worth spending a lot to market it."

All of this is false.

Junk food isn't cheap calorie per dollar or various nutrients per dollar (source- efficiency is everything) further, fresh vegetables are the cheapest sources of nutrition.

And humans are able to eat the foods mentioned and turn into energy through various metabolic processes.

The author seems to parrot "common" knowledge, but it's not factual by any stretch. (Ok maybe trans fats, but those are borderline illegal)

It is also possible to mistake results based on skill for luck and randomness.

It feels better to believe that the success of others is due to luck and that your failures are due to randomness. Sometimes, other people are more intelligent / skilled / harder working.

It is certainly possible to beat index funds, many do so, some of them are mostly lucky, some of them are mostly skillful.
I believe that this has been widespread on social media but do you know of any examples where reputable media outlets were fooled by a Photoshop? Not saying I don't believe you but I watch plenty of news and haven't personally seen much of this.

You may be interested in this 11 minute video of Ben Felix, of PWL Capital in Canada, entitled "US Elections vs. the Stock Market":

> With the upcoming United States presidential election, lots of investors are worried about how the election outcome will affect their investments. This is not a new worry - elections are stressful times and it seems obvious that the outcome should impact the stock market. Rhetoric from across the political spectrum certainly doesn’t help.

> Fortunately, the relationship between stock markets, elections, and political parties has been studied extensively, allowing us to step back from the rhetoric to consider the historical data and the theories that explain it.

> I don't think that's entirely true. When most people talk about investing in index funds they're largely talking about funds like eg. $SPY, not total market funds like $VTI.

My personal performance of investing in all three categories (total market index, S&P 500 index, NASDAQ-100 index) matches every chart you can find online over last 5 years; the total index funds are carrying the baggage of all that "not S&P" weight and are worse returns than the 500, with the 100 achieving almost twice the performance as the 500 (near 24% returns over 5y).

The new "target retirement date" funds are falling below all three with the highest expenses and lowest returns, worse than a generic total market fund, $0.02 anecdata from a lifetime passive investor in index funds. (I'm still in the red this year on small cap specific and world growth and similar "diversification" funds, they're by far the biggest money wastes compared to passive index fund investing in my portfolio)

Any form of art or engineering requires a huge amount of background knowledge and/or practice experience, and artists and engineers should have a better grasp of the technicalities than the audience.

But audiences tend not to care about specifics. They care if you can live up to expectations and provide the experience they expect. So if a performance is lacklustre, or a piece of software is stupidly designed from their POV, they'll know something has gone wrong - but they won't know (or care) exactly why.

Amateurs and wannabes tend to fethishise equipment instead of art. There's a lot of "If only I had that equipment I could do this properly."

The reality is that expensive pro-grade equipment only ever adds a final layer of polish. It's also good at not getting in the way with unnecessary frills and complications.

So a world-class professional with a budget guitar will always outplay and outperform an amateur with a pro-league instrument. No exceptions. And a professional photographer will always take better photos with your phone than you will. And so on.

The professional may notice some polish is missing and they may have to work harder than usual - but they will be able to do the job, while an amateur won't, no matter what they're using.

I have a different problem with LCDs. I still think they're too bright. With a CRT you could set everything to white on black and you had almost no light coming out of the screen. Also brightness meant brightness and you could turn it way down for when working in dim light or darkness.

Of course i'm talking about text work here.

Maybe when OLED monitors become affordable we'll go back to monitors that aren't basically a lamp shining into your eyes all day. At least the oled on my phone looks like it doesn't put out light where it shouldn't.

For gaming, i'm not latency sensitive, but then i don't play twitch shooters any more. I'm more the kind that buys mid-low range video cards and turns on the fps limiter where it's available.
No, they seem explicitly designed to avoid interactive use an end user.
My thought is that human speech contains a huge amount of delicate, not conciously noticable quailites that we are innately attuned to pick up on but find hard to explain explicitly.

This is also true of visual facial expressions, but deep fakes know to avoid close ups on the face otherwise the deceit would be apparent, and we are accustomed to seeing faces from afar. Audio on the other hand, we just dont accept perceiving it badly: We'll ask the person to speak louder and clearer, turn up the volume, come closer etc.

Looking from a different angle, I can see few valid reasons for using cosmetics:

1. Cosmetics often includes medical/dermatological products which are essential for some people.

2. Cosmetics can be used not just for "vanity" but to cover big scars and other unwanted-attention-invoking skin conditions; similar to how plastic surgery may be life-saving for some folks and enable them to live a "normal life".

3. Seeking beauty/aesthetics is not a bad thing in itself

I assume, though, most cosmetics are used for nugatory reasons, and we should always questions whether these above use cases really justify killing millions of animals.
Of the 193 vaccines in development, 5 of them use squalene (GSK, Clover Biopharmaceuticals, Seqirus/University of Queensland/CSL, Medicago Inc. and Farmacologós veterinarios SAC/Universidad Peruana Cayetana Heredia). None of those five are among the eleven that are currently in phase 3 trials.

I think the core idea is that it actually gives you an inverse function, based on your regular (in the DSL) function definition.

There's as far as I can tell no inherent need to call the regular function first - given any function f, you get a callable inverse function ~f.
The same has happened with whitetail in the eastern US, and a lot of people around here are still foolish enough to get upset with the DNR when they do a cull. That the resulting venison goes to homeless shelters seems not to move these weepers over Bambi; presumably, in their coldly rational utilitarian calculus, the life of a deer exceeds in value that of a human, at least once the human's circumstances have been far enough reduced.

Yes, I'm making fun, a little. I think that's fair in this instance. Someone who has taken the time and thought to identify utilitarianism as a philosophy on which to base consequential decisions has I think no excuse for not having likewise studied ecology, and the modern history of the human role in ecosystems, to at least the minimal extent required to recognize that ecology is really complicated and humans don't understand it nearly so well as we like to think we do. When we behave as if we did, we break things that very often can't be fixed.
> You're not wrong, but for most people, most of the time, this quibble is not worth getting into.

Sure. I assumed we were talking about whether passive investing could potentially cause negative effects at scale, not whether your average person should invest or not. I don't think the latter is much of a discussion (i.e. yes, they should).

When people criticize passive investing, they're largely criticizing increased institutional passive investment, not retail investors--retail investors don't generally affect the market much one way or the other. And yes, even many institutional funds invest in indices that aren't just total market indices.

If the concern about said passive investing is valid, this of course may end up affecting many average americans down the line, eg. CalSTRS is one of the largest funds in the world.

A TCB should be dozens of lines, not thousands. More code means more places for more bugs to hide.

My experience in Safe Haskell was that, if you have to ask each module individually whether it has a safety property, then you've already created too much work for yourself. Instead, require every module to structurally encode the desired invariant.

Or, in fewer words: If you want memory safety, don't have `unsafe` blocks.
