"By going out you're already putting people at risk, tracker or no tracker attached"

This is completely false because, with contact tracing, we can probabilistically determine who has likely to have had contact and therefore be infected, which is a proven technique for the suppression of COVID.

Korea has implemented this solution, it works, and their economy is open.

By venturing outside without contact-tracing - we know the results: Italy, Spain etc..

Just the opposite ... it's the 'privacy fanatics' who are having difficulty grasping a situation that hits at their preconceived sensitivities.

'Just go outside' will kill is quickly.

'Shelter in place' will kill us slowly.

'Contact tracing policy - (followup, quarantine for those affected) means we can go about our business roughly as normal with only the slight inconvenience of having an 'app' on our phones and possibly wearing masks.

I'm sorry but it's the anti-contact tracing people that are the tip of the anti-science community right now.

Anti contact tracing people are the new 'anti-vaxxers'.
Yeah, walking into an average home built 35 years ago and the average one built 5 years ago, the difference is huge. Older ones definitely feel like they'll just pancake during a moderately large earthquake. They also completely lack insulation and many don't even have double pane windows. Nobody wants to buy houses like that in this day and age.

>Or alternatively it's in bad neighborhoods. (bad is relative if you are from the US)

I've never been to Japan, but I imagine that a bad Japanese neighborhood is incredibly safe compared to a bad U.S. neighborhood. In a bad U.S. neighborhood one has to regularly take precautions in order to not be physically assaulted or even killed by other people.

That said, of course I'm not thinking that Japan is some paradise. What I hear/read about their justice system and their stifling conformist culture doesn't sound very good to me.

Definitely NOT recommended for absolute beginners. I tried reading this as one of my first programming books and it confused the hell out of me. There are much better introductory books/courses - my recommendation is "Watch and Code - Practical Javascript" if you are an absolute beginner and want to learn javascript.

Eloquent Javascript is a good book now that I know more about Javascript, but please NEVER EVER recommend it as the first book for an absolute beginner.
Because space and time are just two aspects of the same thing. Your velocity isn't a 3-dimensional vector--it's actually a 4-dimensional unit vector, and the direction in which it points is what you consider to be the future. The non-constant nature of 3-velocities that we actually measure is just a result of the non-constant nature of projections of that 4-dimensional velocity vector onto different 3D spaces--i.e., different inertial frames of reference.

To get an intuitive idea of why this necessarily results in symmetrical time dilation, imagine two people walking along non-parallel paths at a constant rate on a 2D surface. From either person's point of view, the other person has a one-dimensional relative velocity, either towards or away from the observer, and that relative velocity depends on the angle between their paths. One-dimensional acceleration is just rotation in the 2D space. Now, what happens if you project one person's path onto the other person's 2-velocity? The projection will be shorter! And remember, the direction of your velocity is the direction of forward time from your perspective. So, from your perspective, the other person has traveled less distance along the time direction than you have, because some of their constant-velocity path was used up traveling in space instead. I.e., from your perspective, time has slowed down for them. But, projecting your path onto their velocity vector also results in a shorter path--so the effect is 100% symmetrical!

Now, this analogy fails in two ways because the real universe doesn't have any meta-time that you can use to observer where the other guy is "right now", and because spacetime rotations are hyperbolic rather than Euclidean, but those two sources of error happen to cancel out nicely and you get the correct result that moving objects appear to move through time slower.
You can do the exact same thing in nearly every part of the USA except Blue cities where regulation has moved home ownership out of the poor's reach. For example, California, new construction requires an electric vehicle outlet in garages. If you're poor, you have much better things to be spending $1500 than some charger outlet they will literally _never use_. Instead, regulations on how people want to live their lives and shelter themselves cement a cycle of poverty into these areas.
There are two types of Fourier magic.

1. The magical orthogonal basis functions: complex sinusoids. Shifting of a time signal just multiplies the Fourier counterpart by a new phase (relative to its represented frequency). Thus transforming to the Fourier basis enables an alternate method of implementing a lot of linear operations (like convolution, i.e. filtering).

2. The magic of the fast implementation of the Discrete Fourier Transform (DFT) as the Fast Fourier Transform (FFT) makes the above alternate method faster. It can be most easily understood by a programmer as a clever reuse of intermediate results from inner loops. The FFT is O(N log N), a direct DFT transform would be O(N^2)

A mathy demonstration of this at https://sourceforge.net/projects/kissfft/
Crypto and practical security. I get tired of the circular “don’t roll your own crypto unless you’re qualified”. How does one become qualified? I don’t feel like I know how to evaluate many of the arguments people make for or against technologies people argue about on HN, such as Signal or different password managers. I feel like “security through obscurity” is a bad thing, and “layers of security” are a good thing, but isn’t all security obscuring something, and how does one evaluate whether a layer is adequate? “Just use bcrypt” - okay, help me understand!
> The problem with this assumption is you can’t keep everything else identical. Population X and Y don’t grow up live and die in exactly identical areas expect for different radiation levels.

For most other things you would do a placebo controlled trial, but it might be hard to get people to sign up for a trial where you're giving them enough radiation to expect to cause a significant number of them to get cancer.

So controlling for confounders is really the only thing left if you want an answer.

And it works pretty well -- at least better than nothing -- if you actually want the answer. The problem with it is that it unfortunately can also produce whatever answer you want from a political perspective by reverse engineering which confounders to control for based on which ones shift toward the desired outcome, so you can't trust somebody else to do it for you without checking their work at a level of detail that basically amounts to redoing the analysis yourself.

Admirable dedication! It feels like a crime to go so far with medium format and not show large resolution scans, though. Maybe it's to avoid hurting the sale of prints?

Understandable I guess, but considering the amazing resolution you can get from medium format, this just really leaves me itching to see a large image.

Thanks for the detailed analysis, I was near ready to take my pitchfork out.
The big problem (well, one big problem, not the only one) with Medium is that it's actually really terrible for discovery.

If you want your posts to be seen, the main thing to do is to try to get them linked in as many places as possible. If you use Twitter, tweet the links. If you use Reddit, post the links in an appropriate Subreddit. (Those can drive a surprising amount of traffic.) If you're in niche communities that have their own forums, Slack channels, Discord servers, Telegram channels, etc., etc., and your article is on-topic, link it there. You need to do this all in a way that isn't spammy or obnoxious, for obvious reasons: you're saying "I think this link will be interesting to the audience here," but if you're really saying "OMG I need the hits click on me click on me click on me," people will pick up on it.

And then... hope. The chances are the post still isn't going to go anywhere in particular, but getting the link seen and shared by others is what will eventually drive an audience to it.

The more articles you write, the more likely you are to get something once in a while which catches on. Writing at least semi-regularly also helps. And, not to put too fine a point on it, but you have to actually have something interesting to say. "Join a New Developer on Their Journey With The Same Technologies The Last 58,213 Developers Who Wrote 'My Developer Journey' Blogs" will probably not cut it.

None of these things are specific to Medium, obviously, and frankly I don't think posting on Medium is a really great choice. If you're looking for a free blog, start it at WordPress.com, and maybe pony up the $15 a year to connect it to a custom domain. (I blogged at Tumblr for years, which can actually be set up to be a terrific blogging platform if you choose the right theme, but I'm not sure about its long-term viability at this point.)
I think this is more about the terminology than the actual concepts. This is like in biology, where you classify things as living and non-living, but then you encounter things like viruses, which would depend on the criteria for a "living thing." Or, is a gel a solid or a liquid? Again, it has properties of both states of matter. Similarly, in order to classify phenomena as waves or particles, you look for common attributes between the things you observe. But light exhibits properties of both.

It's analogous to the reason coal was necessary even after we had electricity: short positions enable the production of put contracts. By selling you a put option, I'm taking a long position on the underlying stock. So I probably want to hedge that by selling a bit of my existing stock. But if I don't already own stock in that company then, without short selling, I can't provide that liquidity.

Short selling typically involves the sale of borrowed stock, mediated through dealer-brokers, so the stock that's sold short does exist. So there's no issue with supply.
"We don’t fact-check political ads. We don’t do this to help politicians, but because we think people should be able to see for themselves what politicians are saying..."

This is such a cop out. Many (I'd even venture on most) political ads on Facebook don't represent what politicians say.
Are those neighborhoods safe, or are they the kind of places where you have to regularly worry that you might get physically assaulted?
I would consider myself pretty close to an expert with JavaScript. I've been using it for 5 years professionally, currently use ES2020. Fairly familiar with Node 12, V8, etc. But I'm always worried about those situations where you dont know what you dont know. This might sound strange, but would anyone recommend any reading material or blogs for someone at my level?
> even the greediest tech company (oracle!) Has not thought of to charge for documentation

Oracle sells products/services that thousands or millions of organizations purchase. That's a completely different kind of business arrangement than something that a single entity purchases once. If you hire a software consultant to build you a custom system, they're definitely going to charge you for the time they spend writing documentation.
Permanent schizophrenic zombie, maybe a bit extreme, but severe and traumatic long-lasting psychological damage is a not-uncommon phenomena.

I had a fling with psychedelics in my teens, and everything was great until the one time it wasn't. I was taking psychedelics pretty much every weekend, and by my count have tried over a dozen of them.

Had an experience with LSD which completely shook me to my core and gave me such severe PTSD and trauma that every night I started to have massive panic attacks and needed medical help. My entire worldview and perception of reality was shattered, I wasn't able to "anchor" myself anymore and it all felt like a sham. I was completely dissociated. I also got HPPD: to this day, everything has a sharpened oil-painting type texture to it that increases based on my anxiety level, and I'm sensitive to visual + aural stimuli (loud, brightly-colored places are unpleasant). If I get too anxious, I start to dissociate.

It took ~2 years for the PTSD to subside for the most part, but still if I am under a lot of stress I am liable to have a panic attack and get flashbacks and need to go find somewhere quiet to sit somewhere alone to try to work through it.

LSD being the particular substance has nothing to do with it, in my opinion. I was young, dumb, reckless, and played with fire then got burned. It could have happened with any of the other dozen psychedelics I took, but it just so happened to be LSD the one time that it did.

But I want to add, that while giving me the most nightmarish, traumatizing experience of my life, the best/most positively-profound experience has also been on the same substance. I grew up in a pretty abusive household and didn't do well forming relationships growing up, and had a lot of anger and resentment in my worldview. After taking psychedelics (LSD, 2C-B, Shrooms) and MDMA with the right group of people a few times, my entire perspective shifted. For the first time in my life, it felt like I understand how it felt to be loved, and what "love" was, and how we're "all in this together" so we may as well be good to each other while we're here.

It's been a long time since I've touched any of that stuff and I'm not sure I ever will again, but I don't think it's inherently bad or good. Psychedelics are like knives, they're neutral - can be used as a tool or cut the hell out of you if you're reckless.

Australia has a tin ear when it comes to privacy concerns
So what are the alternatives exactly?

Because we have the whole world on lockdown waiting for someone to tell us.

Unfortunately, without a vaccine or cure - there are only 2 approaches that work:

1) Eradication - like Taiwan. They have a tiny number of cases in full quarantine. Nobody comes on or off the island without being checked. So they are in total isolation.

But we can't do this.

2) Contact tracing - like Korea. They keep the virus under wraps by aggressively isolating cases, using social policy centered around contact tracing. Of course, they have masks, widespread testing, but a very asserted focus on contact management. FYI we have to get it down to low-levels before this policy can be implemented.

But it works.

Regular 'social distancing' does not do enough. Right now - we are coming out of our 'lockdowns' but the virus will likely just bounce back - why would it not? Other than the fact weather does play a role and it's getting warmer, there's no reason for the COVID growth to come back to where it was.

So either you stay away from other people - or - at least you consent to inform them if somehow you were near them, which requires contact tracing obviously with the addition of good operational capabilities there, it's not 'just an app'.

Law. How much of it rests on technicalities, and how much do judges care about the essence of the facts of a case? You only hear about the weird outcomes on the news. For example, I was once working with an attorney because my landlord didn’t supply heat in the apartment. I started keeping a temperature log, but how would a judge know that the log was accurate? Do I need to prove that my thermometer is accurate... etc. In practice, no, but how can I better reason about what is “likely” vs not?
Really late to the party, but I love this concept. I feel like this would be really difficult in an open office/shared office.

I enjoy team based offices, 7-10 man rooms. Even in there, this would probably be a nightmare unless you had this tech running in real time so you don't get microphone crosstalk/echo.

None the less, I really like the spirit of the system.

I worked at Locus back in the 90s, when this technology was part of the AIX 1.2/1.3 family. The basic architecture allowed for heterogeneous clusters (i386 and i370 -- PC's and IBM Mainframes all running on the same global filesystem.) Pretty sure you couldn't migrate processes to a machine with a different architecture though. It was awesome to be able to "kill -MIGRATE" a long-running make job to somebody else's idle workstation, or use one of the built-in shell primitives to launch a new job on the fastest machine in the cluster "fast make -j 10 gcc".

Maybe you’ve stopped seeing friends but still have sex your non-cohabitating partner. Maybe you went for a walk with a friend and tried to keep 6 feet away but slipped up. Maybe there was an emotional moment and you touched them before you could think. Maybe you had one person over for a special occasion.

Lots of people have at least some intention to take it seriously, but not the steely heart for the hardcore isolation that’s required.
The amount of time you experience is directly related to the length of your worldline--the path you trace out in 4D spacetime as you move through space and simultaneously move forward in time.

It should be easy to see that a non-accelerating object (or person) will trace out a straight worldline. If you ever change your velocity, though, either through smooth acceleration or instantaneous rotation of your velocity vector, you will trace out some non-straight curve in spacetime. If you leave your friend behind and then, at some later time, meet back up again, if you did not undergo exactly the same amount of acceleration throughout your journeys (i.e., because one of you stayed behind and hardly accelerated at all, tracing out a boring straight line path), then you will have different world-line lengths (different "path integrals") between the starting and ending points, and thus will have experienced different amounts of subjective time.

Now, in a Euclidean spacetime, the traveling twin would end up older, because a straight line is the shortest distance between two points. But our spacetime is not Euclidean--it is a Minkowski space, in which acceleration is equivalent to a hyperbolic rather than Euclidean rotation of your velocity vector, so it turns out that straight line is actually the longest distance between any two points, and the twin who leaves and comes back will have a shorter worldline, and thus will have aged less.
I wonder though if the expense is for producing the document, or because Boeing will no longer be the only company that can repair it.
But then again, realizing this problem with the thought experiment is a mark of a sophisticated student. This was the last question on my physics exam in 1991, and I still regret that I went with the simple explanation. I wonder whether the prof was looking for the students who really got it.
That follows from the part I quoted. It would be very unusual for someone to be good at a task they know they don't want to do and that they find mind numbingly boring.
