I'm wondering what you mean by "doesn't seem to be wrong" -- are you doing any calculations? I'm not able to follow exactly what you mean by the quantum amplitude coming from a pair of tennis balls.

My understanding of the spin of a particle is that it turns out, roughly speaking, your spinning tennis ball needs to keep track of a vector along the axis of rotation. This has something to do with the unit vectors in 2D Hilbert space having a correspondence to the group SU(2) (where remembering only the axis is the classical case of SO(3)). Somehow, if you were to take your quantum spinning tennis ball and, by some mechanism (magnetic fields?), slowly rotate its axis by 360 degrees, its spin becomes negative of what it originally was and it can destructively interfere with a tennis ball in the original state. Is this the sort of thing the pair of tennis balls is meant to deal with?

Something I really don't understand is how angular momentum is meant to work... I would have thought it's a Lie algebra thing, but SU(2) and SO(3) have isomorphic Lie algebras.

Disclosure: I don't know any quantum mechanics, just some math.
Leetcode, if you want to pay for UX.

If you don't want to pay, just get the list of former questions from the internet. [1]

Many of those questions may no longer be asked, but if you can ace them, you should have few problems with similar questions/variants thereof.

This is not a skillset that develops from doing your day job. You have to deliberately practice to get good at this.

I was not happy to find the Fitbit only works by syncing through their service - eg they get all of your data, and vigorously opposed requests to just link to HealthKit and not upload data.

Now it seems they were deliberately making sure they had your data so they could (in effect) sell it.

I’ve held off on an Apple Watch for the longest time due to battery life and size, but it seems like that is now the only option. You can’t trust any company to have access to your data.
AirPods (and earbuds in general) just don't deliver the sound quality unless you make it loud enough that probably hurts your hearing on long run due to nature of their design.

They are comfortable and very useful to have phone calls but nothing more unless you are in quiet environment most of your time.

Refusing to allow that content as paid ads doesn't make the content go away. It just makes people game the system to get views instead of paying for views. Then the moderation problem would be even harder.
>My intense skepticism of cryptocurrencies is probably the issue on which I am most in disagreement with many close friends, professional acquaintances, and some of the smartest people I know. That is part of the reason why the hobby of peeling back onion layers here is so engrossing: people really, passionately believe that there is something here. I’m intellectually curious. The thing people have told me exists should smash my interest buttons: programmable money! How could I not look!?

That is a good question. I'm not aware of someone exploring this avenue, but it would be interesting to see what categories of models are fooled by what types of noise.
Agreed. One of the possible differentiators I list in the article is being an "end-to-end solution." It's going to be a long while before AWS builds AI for accounting, or for optimizing industrial operations, or for... you get it.

Again, you’re damned if you do and damned if you don’t. In fact in this case we’ve already been through this. Instead of “why does Facebook allow possibly false ads” the discourse instantly becomes “why did Facebook allow this possibly false ad to go without a marker / why did Facebook put a marker on this ad that’s true in spirit”. For every action there is an equal and opposite hit piece.
Not unlike New York City. But, how about Finland? They also ride bikes a lot more than most US cities, and Finland definitely has harsh winters.

Edit: As for summers, I've regularly biked in Texas throughout the summer over many years (I've lived without a car quite a bit in Austin). The peak of the day is rough, but the usual commuting hours aren't too bad. New York has nothing on Texas summers.

I've started blocking delivery truck drivers back. I'll stand directly in front of their passenger side door to block them from returning to their vehicle (not touching their vehicle). Some drivers seem really irritated to have to walk into the road, which just shows that they know their parking is dangerous to cyclists. The goal is to add time to their delivery, as I think they only park in the bike lane to save time. I think if enough cyclists did this then delivery truck drivers might start to avoid the bike lanes.
Quantum mechanics is just math, and it’s possible to work the equations and get valid results even if you haven’t the slightest understanding of what any of it means. There’s no such parallel with Buddhism.
I find what I like most about ordering pizza online is that you are looking at a menu that calculates the cost and lets you put together the order. Then instead of having to then call someone up and read it out to them, you click ORDER and you are done.

The bad bit about using DOMINOS website is the shitty popups and 'you want this?' 'you want that?' yum-cha style experience that wastes a lot of time.

Your “truth” is an inference that you are drawing based on circumstantial evidence that contradicts the witness’s story. Even if I agree with you that conclusion is probably correct, in US law we would treat that as a “disputed fact” that would require a jury to resolve.

I think Facebook shouldn’t moderate political content, full stop, but if it did, surely the limit is things that provably false without making judgment calls or evaluating credibility. E.g. “Hilary Clinton was indicted for her emails but Obama pardoned her.” It’s shocking to me that anyone would espouse Facebook making editorial decisions on political ads based on inferences from the evidence that in a court of law a judge wouldn’t be empowered to make.

And if Facebook moderators should be able to make inferences and weigh credibility in deciding “truth” doesn’t that circle back to my point about education spending? The US spends more on education than all but 1-2 other OECD countries. Can’t a moderator infer from that the assertion that schools are underfunded is false?

China's record for the last 40 years is lifting billions of people out of poverty while we stomped around bombing places and killing millions in the name of exporting our awesome values. Oh, and our infra is falling apart compared to theirs while we spend all our money on bombs.

So glad I got my GF to get rid of her Fitbit. She had the first two models and both were a nightmare in terms of issues. I got her a Polar Vantage and she just loves the thing. Never had any issues with it and the data you can get out of their apps are incredible.
I suspect it's because patio11 is employed by a payment processor, Stripe. Stripe's business is taking a percentage of payments / transfers. One of Bitcoin's usecases is making payments / transfers with lower interchange / wire fees than existing financial system. The argument is the same as saying that someone employed by gun manufactures is biased when writing about proposed gun laws.

(I don't have a view on whether patio11's employment has influenced his thinking. I just wanted to suggest what the grandparent's thesis may have been.)

Chicago has been doing a pretty good job of building out bike lanes. But it needs to be taken further still, and more quickly.

However, the initiative needs a more robust implementation, with more consideration of driver behavior and parking needs. This is evident as many delivery trucks, Ubers etc. park in the lane (albeit, with emergency blinkers on, but it's a moot measure regardless) and push bicyclists into traffic. So while the bike lanes probably improve safety and reduce deaths overall, it can and does introduce a new, very real hazard: the necessity of bicyclists to suddenly merge into traffic. And this abuse is pretty rampant.

The hanging fruit is simply implementing stiffer penalities for such violations but this seems lacking. Coupling this with more temporary parking zones might be a solution. Then again, I'm not a civil engineer, just my observations and half-baked thoughts concerning the matter.
there are a few states on there that are "DRE w/o paper trail" which is "pure digital voting".

Some of those states are now, or will become swing states. As we saw in 2016, where the presidential race was decided on a 400k margin of error across 3 states, it doesn't take much.

It’s difficult to deploy Erlang apps in Erlang-style using Docker. The style I speak of is zero downtime deploys where the VM is never turned off, but is updated with new software as a living organism.

You can run BEAM apps in a container the same way you’d run any other app. It’s possible. But BEAM is less like a PHP/Python/Ruby etc interpreter and more like an abstraction for the OS (some might even consider it to be one). When you’re in Erlang you think in Erlang and the runtime abstracts things like processes, threads, and network partitions away... so you tend to want a big beast BEAM instance (or a few big beasts) rather than a lot of tiny ones (as one might scale up a horizontally scaled app like one on Heroku dynos).

It can be done. It’s just kinda going against the grain.
References to support the claims would also be helpful.

Sorry if that came across wrong. I may have misinterpreted the comment as being from the perspective of someone with work experience in these matters.
That's really weird. I didn't know this was a thing but I had a dream a couple days ago that I was using a language in which everything was a string (like Lisp but with strings instead of lists). Guess I'll have to give it a whirl.
A friend, who got me interested in the devices, had the same issue. His died. Mine, I stopped using, when it detected I was asleep for 3 hours one night and I was definitely up and using my phone for the entire time. The only reason I got it was to monitor my sleep. It is apparently useless for that.

It's bad for the US - that they have sinned does not mean they should be any less worried about someone else having power over them.
This will get more people on bicycles, which will almost certainly make the problem worse, unfortunately. No amount of lane protection prevents collisions in intersections, which is where nearly all the deaths happen. The problem isn't the amount of protected lanes; it's the rampant amount of comically unqualified drivers. The two tearjerkers from the article are typical: an 18 year old blowing a red light and someone driving without a license.
Your comment seems like the kind of problem the comic is arguing against. To paraphrase the final panel: "Quantum computing and Zen Buddhism are easy to get completely wrong and therefore equivalent."
> And all the U.S. had to do is make drugs illegal, and it would disappear. (Or not.)

Well, yeah. Making drugs illegal makes them disappear. From legal sources. The illegal sources share a similar set of problems as noted. Am I going to get what I paid for? Will I get all of what I paid for? Will there be repercussions? How safe is this?

The drug market being illegal means that for the vast majority of people it's only worth using for fairly inconsequential things. Recreational drugs for the weekend or the equivalent. You might not want to source your cancer drugs there for the same reasons you might not want to source your car or house loan from some random internet entity. Trust. And dealing in an illegal market makes the higher levels of trust very hard, if not impossible, to achieve.

I think the point is that cryptocurrencies will be relegated to second class currencies for as long as they can't or aren't treated with the same trust a fiat currency is.

Thats not quite true since the early 2000s, when dictionary structures came around. Tcl also has strong built in object oriented support since 8.6 (2012) so if you like that sort of thing its there.

If you are dealing with quoting issues that's probably due to you using an older version like 8.3 or 8.4. Give a newer version a shot!

This has came up in my conversations with friends who work at Facebook and they always seem to use some internal talking points about creating a "Ministry of truth" type of situation. They argue that Facebook cannot (or should not) be the arbitrator of truth. My answer to them is very simple, if you want to be a (social) media company then you have to take some (social) responsibility and not amplify falsehoods in an already charged environment. Corporate profits at the cost of ruining the society by spreading falsehoods should not be an acceptable norm.

Reminds me of Algorithmic Information Theory:

> Algorithmic information theory principally studies measures of irreducible information content of strings (or other data structures). Because most mathematical objects can be described in terms of strings, or as the limit of a sequence of strings, it can be used to study a wide variety of mathematical objects, including integers.

Coding Is Extremely Hard, So We Created an OS Back End to Make It Less Painful
Hi, one of the authors here, the Docker chapter and soon to come Kubernetes chapter hopefully shed some light on this very question. They are not alternatives, docker and k8s complement Erlang.

Jose Valim, creator of Elixir, also wrote about this recently http://blog.plataformatec.com.br/2019/10/kubernetes-and-the-...?
I think we're both saying basically the same thing. So I agree.
There's a lot to unpick here. I'll write a brief response for now.

Ultimately I think there are two parts. You have to realise that free software advocates aren't unlimited in their power. The commercial world is far larger (likely due to feedback effects from, well, money). So there's effectively a race there that free software advocates will find it difficult to win.

Having said that, the world is literally built on this stuff. User facing software is the final, difficult, frontier, because marketing costs money, user studies cost money, AB testing costs money, and telemetry and stuff like that allow commercial entities to gain market share using practices that are incompatible with the free software ethos.

> you can't expect them to make sacrifices.

I very much do expect people to make sacrifices and I think that people who aren't willing to sacrifice for the greater good (unrelated to free software; I'm talking in the general sense here) are either misguided or outright malicious.

As a strawman example: "we" shouldn't need to create an electric pickup truck in order for people to stop driving 10mpg guzzlers around cities for ego reasons. We should probably just tax the hell out of it instead and require them to "sacrifice".

Because ultimately there won't always be a magical solution. I own a Tesla and I think they're great. But if society decided - actually we should probably not like, build roads all over the countryside and disrupt habitats - I'd be fairly happy to give it up. And that would be a sacrifice, but it would make sense to do so, because it's a personal sacrifice for a greater good.

I enjoy learning new languages. In my day job I spend most of my time writing JS (ReactJS specifically) building dashboards and other internal business tools. Sometimes I need to build API's or perform tasks that just cannot be done in the browser and I take the opportunity to experiment with other languages.

A few examples:

- We purchased a cheap USB duplicator (10 slots) to copy the contents from a master USB to the clones. It worked, but wasn't a great solution. It was slow, error prone and when it failed you never really knew what USB was having the issues (or what went wrong). Using a Golang backend and ReactJS frontend I created an alternative which had a nice GUI showing what files were copying, the percentages complete, error messages, etc. It was a far better solution and using Goroutines it was fun. We ended up scaling the system to 100 USB's at a time and that was fun to watch (lots of blinky lights :D). The solution didn't take much time to write (Golang was quick to learn) and we finished the duplication WAY sooner than the due date.

- We needed to automate a bunch of DNS stuff with CloudFlare. I ended up creating a parser for a custom config we wrote, hooked it up to CF's API and we ran it as a service. The language I used for this project was Nim[0]. I liked the syntax and the final binaries were TINY and FAST.

- More recently I was approached by an IT guy at the company that manages all of our software licenses. He showed me this command line tool he uses to query all licenses and goes through the cryptic output trying to figure out what licenses were being used, by whom, etc. I ended up using Go to parse the command and serve a ReactJS application with all sorts of bells and whistles (reports, history, alerts, etc). Since the application is browser-based he can even use it mobile which he loves.

- I've been working on some prototype BLE Mesh stuff in C, but that is a ways out and not yet worth mentioning much more.

Rust has held my interest for a while as well, just waiting for the right project to come along.

Nothing wrong with having both. TLDRs will always be popular.
No, it's not tax. It's just systemic discrimination. If you're ugly I think you should earn just as much money programming as if you're pretty. Serving food and waiting tables doesn't require you to be pretty, it requires you to be attentive and personable.

Having lived in the US for closing in on two years, the tipping system and sales tax/fees being tacked on at checkout is one of my bigger pet-peeves. This would be illegal in other places as that's highly deceptive marketing.
We’re taking about paid advertisements, not mere posts. The volume of paid ads is infinitesimally small compared to user-generated content. It should be very straightforward to review ad submissions to determine whether they are selling a product or service, as opposed to an idea, promotion or complaint about a person or group of people, and deny by default if there’s any doubt.

Apple has allegedly had spO2 monitoring capability on Apple Watch for years too without making that function available in production. I wonder if there's a similar reason for this. I mean, I can buy a $12 spO2 monitor on Amazon, and most clinics seem to use that exact model... why not let my fitness device do it too?
You do have to weigh the severity of death against the frequency of lesser injuries. Hippos are more likely to kill me than mice, but I'm much more worried about the mouse problem in my building than I am about hippos.

And precisely who do you think should be appointed to head your “ministry of truth”?

For example, I believe Facebook employees currently skew 90% Democrat. Should the committee seek out and add more Republicans in order to have a 50/50 split reflective of the nation, or is a 90/10 split okay? If so, how do you justify this to the other side?
Apple Health seems to allow exporting all the data as a file, including individual measurements from the watch (those come every second some times). Haven't tried it yet though.
