Somewhat more interesting is that (E, px, py, pz) form a proper 4-vector, which means under rotations in 4-space its length does not change.

To see this, first note that in flat 4-space of our universe (known as Minkowski space), experiments show that our metric is diag(1, -1, -1, -1), thus giving the length as

E^2 - px^2 - py^2 - pz^2

This should be a scalar, i.e. a constant that does not change under transformations. So we label it m^2, the rest mass of the object. From there it follows that

E^2 = m^2 + px^2 + py^2 + pz^2

You may be wondering where all the 'c's went. For exposition I chose units where the speed of light is 1. We can easily reconstruct where the 'c's should go by looking at the relevant units:

E: m * v * v
p: m * v
m: m

Thus we need to multiply masses by c^2 and momenta by c:

E = (mc^2)^2 + (px^2 + py^2 + pz^2)c^2

Compare with perhaps a more familiar Euclidean 2-space where the metric is diag(1, 1) and the length is given by the familiar Pythagorean theorem. In such a space we can explore the set of transformations which preserve the length, and see they are of the form

(cos x, -sin x)
(sin x, cos x)

In Minkowski space, the set of transformations can be categorized into familiar rotations in 3-space and so-called boosts in 4-space where some space dimension is rotated into some time dimension (or vice versa). This gives rise to the famous observations of time dilation and length contraction when considering relativistic speeds.
I’m curious, when a young person, a friend, or an inexperienced developer at your company asks for your opinion about something they’ve made, do you respond with: it’s a shittier product that other people have done better?
The main role of the police is to act as a deterrent for criminal behavior, not to fight crime (though they do both). Being seen by everyone who drives by fulfills the deterrent role, while allowing them to generate income for their precinct that keeps taxes lower.

that's the gist of it, abstractions are always imperfect in some way and leave the door open for interpretation, at which point if team member don't communicate each module intent efficiently code responsibilities get mixed and entropy rise dramatically, causing more bug per line of code written.

imho an important figure on large projects that is largely ignored or conflated with "the architects" is the oracle, or the guy people ask where new feature/code should go. not in term of application structure or component design, but at a lower level, at modules and interfaces level.
1.7% tax annually on property certainly doesn't seem cheap to me. I pretty much pay the same in interest on my mortgage in Norway.
Yes, that's what the Unicode consortium is doing.

If you look at https://unicode.org/versions/Unicode12.0.0/ you will see that emoji is just a small part of it.

I know that there is some controversy, in particular regarding han unification, but in practice, Unicode works well enough.
Absolutely not. While working for Amazon we had to think about a lot how to "shard" our fleets to have the least amount of items in every cache and maintain high hit ratios. If you let all traffic hit a single cluster your cache hit ratios will be terrible and most customers are going to experience worst case latency which is absolutely do not work for popular websites.
> A "hero" project is one where 80% or more of the contributions are made by the 20% of the developers. ... We identify the heroes developer communities in 1100+ open source GitHub projects.

My scepticism has been piqued to the extent that I call b######t.

Open source projects. Projects contributed to by people in their spare time, or perhaps with some corporate backing with developers on the payroll, and often with quite different governance models.

Should we therefore be surprised at the widely varying levels of contribution? Should we be surprised that those who do more work on the projects tend to make contributions resulting in fewer bugs, perhaps because they have a much better understanding of the projects due to their greater familiarity with them?

Whatever: OSS projects with contributions coming in from all manner of sources outside the core team aren't necessarily terribly similar to having a team of 6 - 8 working on a project full time within a company. The only similarity being that a relatively small core team do most (or all) of the work.

Colour me not even slightly surprised. My blunt conclusion is that the idea software projects "need" so-called "hero" developers is extremely questionable based on the data presented[1].

[1] Granted I've done no more than skim the paper but this comment, from page 3, amused me: "Most prior researchers deprecate heroism in software

The US health care system is the least efficient of all the developed world, in terms of results vs expense. In many sectors, a competitive market gives the best results. In health care, that's just not the case. The free market isn't the be all, end all solution that free market advocates want people to think it is.
Taiwan is not a province of China, but an independent country.

Other than that, I agree with your assessment: Taiwan's thriving democracy undermines and contradicts the Chinese Communist Party claim to power, in particular the CCP's narrative that democracy is neither needed nor wanted, nor desirable for the Chinese people.

Japan's population tripled in the past 100 years, they have no natural resources and live on imported oil, minerals and food. The population density is very high if you consider the geography (many mountains). A slight decrease is not a bad thing in such circumstances.
I think of it as a trade-off between the tool perfectly designed for the job and the tool that can be used for the job of which I'm already an expert user.

As an example, my current team's codebase is Python and C++. When we need to do some basic Linux scripting (check if this file exists, if not send an error email), the two prime candidates are Bash and Python. Bash might be exactly designed for this type of thing, but a lot of the team would need to Google stuff like "bash logical and of two booleans" for Bash where they already know the Python syntax. My current rule of thumb here is "<10 lines of code: use Bash. else use Python". More generally, I often try to err on the side of using the tool I know than the unknown tool that might be perfect for the problem.
Certain segments of the economy get priced out of the area. If you want to go to a restaurant, there need to be places for the waiters and cooks to live. If you want someone to pick up the trash, there need to be homes for garbagemen. A hospital needs nurses, janitors, and receptionists as well as doctors.
I would imagine that poll workers have a minimum age. Their death rate is going to be substantially below, not above, the average, because most deaths are due to (complications associated with) old age and that population is very unlikely to be working counting votes.
What makes them major economic centers is that a lot of useful work is done in them.

High real estate prices is just rent-collection by landlords.

Vancouver is an outlier that makes its money as a destination for laundered international money. The other economic centers actually produce, and export useful goods.

In Malaysia, any citizen can apply for the job. Also being paid. I worked as a worker once in the last election during the fall of Barisan Nasional. Luckily for me, the place of voting that I was placed in doesn't have many voters compare to other places so it's not tiring as it may seem. All in all, it was a fun experience one should get once in their lifetime.
This study (if you could call it that) has already been shown to be heavily biased and misleading.

Here’s an article with comments from Norwegian fact checking site: https://www.faktisk.no/artikler/NKl/forskere-mener-tysk-elbi...

One flaw is that it does not account for energy used and emissions related to extraction of oil and production and distribution of diesel.

Another flaw is that the estimate for CO2 emissions in the production of the battery makes assumptions that we know are false in the case of Tesla.

But the whole premise is also bogus. The point of EVs isn’t to cut a few percent of CO2 emissions. It’s to build towards a future where we cut ALL emissions. And it’s the only technology (possible alongside fuel cell tech, which is a branch of EVs as far as I’m concerned) that can plausibly do that for the land transportation sector. Sure you need to clean up production emissions and the grid too. But that’s problems we have to solve anyway, and are improving on every year.

We can’t just go toward whatever leads to the most CO2 decreases at a given time. We need a long term plan that actually builds towards cutting all emissions. Studies like this completely miss this point, and so does people thinking their hybrid or EV is personally saving the planet for that matter.. but hey they help drive investments that actually matter so they help even if they miss the point

I print color documents all of the time on my home (Dell C1710nw) laser printer. The necessity of color is heavily dependent upon which type of documents are being printed. Life isn't monochromatic for me.

Now at work there are only rare occasions that I print anything at all, preferring electronic copies of everything. When I do print, most everything is monochrome.
I totally understand where you are coming from. Poly isn’t for everyone, casual love isn’t for everyone, and casual sex is most definitely not for everyone. Not engaging in those things is a valid choice, and if that is right for you, it is right for you.

I will say that casual love != casual sex. You can experience casual love without any sex at all. You can form romantic relationships that do not involve sex. While I personally am not wired that way I have plenty of poly friends who are. The longest running podcast on the subject, Polyamory Weekly, to this day uses the slogan “it’s not all about the sex.”

Casual sex for a lot of people is a much less satisfying experience than sex in a long term relationship. But to be fair, let’s acknowledge that loads of committed relationships also suffer in the bedroom, so it’s not all great there either. Ultimately it depends on you and your preferences/needs. And of course on the partners you select.

Empirically I can say that I experience love towards a partner about 1/10 times or so. Though my sample size is not actually all that great because while poly, I am very very selective. This may be surprising but the reality is that poly doesn’t mean “screw everything with two legs.” It just means that if someone does interest you, you are free to explore that however you want, and your partners have the same freedom. Whether you choose to have one anchor partner who you share your home life with, or you do “solo poly” where you live alone and have multiple partners with whom you have no plans to ever progress on the escalator is 100% up to you. A couple of people I know actually identify as monogamous, while practicing Polyamory through their partner being poly. Not my cup of tea, but that seems right for them.
As always it depends what you mean, I'm all for having IoT devices on my local network, exposed in safe ways through some kind of gateway device. This models most homes in some way today anyways.
"it seems far superior to traditional higher education, since the schools success depends on the success of the students. "

Higher Education is not 'Job Training'.

Also, nursing is not software.

I would love for nursing school to take on some more advanced methods, but I'm doubtful lambda is the way to go.

My hunch is that aside from some very critical basis things ... that much of nursing is learned on the job.
There is however some government action in terms of government ad spending on these platforms, and the many, many billions of dollars in tax incentives/abatements that have been handed over to Google etc.

That may not reach the level of government involvement needed to claim that universal access must be provided; however it should be noted that the government has helped to pick winners and losers in the internet economy.

If you look at the history of China, many times entire governments have been overthrown by a peasant revolt. China is sort of unique in that, other than the French. So to the Chinese: Viva la revolution. Down with Communist Party!

So to answer your question, that's why they are scared and should be the Chinese people have the ability to get rid of the fascist totalitarians running their country -- they have done so multiple times in the past.
To learn Erlang is not that difficult. I think it is a bit harder to understand how to write production ready sacable OTP code. Btw. you should check out Elixir. It is much easier to get into Elixir nowadays and many aspect (like deployments) are solved while with Erlang you need to do a bit more to get the same results. You can also just toy with Erlang without OTP (not really recommended). :)
That sounds fair but nothing the government does works that way. If you asked us all we would pay zero taxes ourselves and enjoy social benefits paid by others.

I like it. Some people have expressed concerns about yet another platform which holds your data. I don't actually have a problem with that as long as you can leave without being penalized. A good way to alleviate those concerns might be a feature where you could download all of your site data along with a guide to setting it up self hosted.

It's illegal to ride on sidewalks here but it really is the best thing some of these people can/should do (at cruising speeds, anyway)
This is the most "that happened" comment I have ever seen on HN.
How much did you pay them and for what tasks? Do you think your fivers paid taxes or had health insurance?
Fair points. I'm thinking about the net effects rather than per act.
I'm glad I'm not the only one who thinks this is nonsense. I wrote a fairly long comment, which you (might) find elsewhere in the discussion, then started reading the other comments and was starting to wonder what other people were seeing that I wasn't.

Short version: the OSS versus every other type of software project comparison seems very apples and oranges.

The only way I can read this is that you believe, of the people that cause a collision with a bicycle (accidentally or otherwise), all (or almost all) of them would just leave you to die on the side of the road.

That is a staggeringly low opinion of humanity.

> after two/three years all the juniors in the "surgery team" model start looking at position of seniority within or outside the company, causing high concentrated turnover in such built teams

Is that a problem?

I mean, the same thing happens with literal surgeons/doctors and residency, where their early years of career eventually end and they expect a mid-level position in the organization.

It sounds like a healthy industry that juniors/apprentices work under journeymen and masters at a large organization early in their career, then move up or branch out after a few years.

I'm not sure why companies expect to be able to cost-optimize away a functioning economy, but remain in business.
So support remote work and the disintermediation of geography from delivering value. Unless you’re twiddling atoms, no need to be somewhere specific in space time. And if you must twiddle atoms, pay a premium for demanding a specific piece of space time that is in high demand.

High rent collection is a symptom of high demand for an asset. If the land wasn’t valuable, the rent wouldn’t be high!

> unobtrusive banner ads

Oh boy I don’t miss the flash animated pop up ads, but that has less to do with forums vs social media and more to do with how the tech has evolved.

That said fb and google ads are pretty unobtrusive because they exert so many restrictions on businesses. If you’ve ever tried to run ads you’d find user friendly restrictions like “no all caps text” or “limit to text in an image”.
You could massively improve the outline simply by making the hierarchy visible. You can nest lists under lists.

I'm pretty sure emoji are what normal people consider images. Their implementation as characters is a mistake, and the source of several problems that normal people have with them. (Most notably, imagining that the person you're talking to sees the same thing you sent.)
> This narrative would be compelling if

I disagree. Saying "don't like it? don't use it" is in a very real sense equivalent to advocating for unethical practices to continue - because that is what past experience shows will happen.

There are countless companies with unethical business practices, with extremely complex, ever changing ownership webs (and looking at the actual people who own the shares makes it even more complex). Figuring out which companies to boycott is much more than a full-time job, and has been shown to rarely work (e.g. there wasn't much of a boycott even in the case of https://en.wikipedia.org/wiki/United_Fruit_Company#Aiding_an...) - the complexity of organizing a boycott for every unethical company is simply too great.
I kind of agree. I got into an argument with an ex once about how love is just brain chemistry. She didn’t like that because that made it not romantic. I think it makes it more romantic: out of basic biochemistry you get “this insane feeling!”

I do think we would all be nicer to each other and ourselves if we didn’t strive to make our partners our “everything”. It isn’t the solution to all our problems but it is a solution to a problem that plagued many marriages/long term relationships. If it wasn’t, cheating and marriage counselors wouldn’t be as common as they are.

I don’t really like labels in general (I prefer to use verbs than nouns if I use one), but poly is what I have been doing for about 7 years now. In addition I have realized that other forms of non-monogamy fit me as well. Love can be felt more or less in those than in poly.
I’m definitely a big believer in Lambda School.

I believe it aligns the interests of:
1)student
2)school
3)employer

Far better than the existing conventional university model in teaching tangible trade skills.

Lambda School can and will adapt to the ever changing needs of employers far faster than universities because Lambda School’s very existence depends on it.

However, does the same apply to regulated and licensed “guilds” like nursing, medicine, dentistry, etc?

Will “guild” like protectionism of their profession impede efforts in this direction?

Lambda School already seems to be making enemies understandably in the traditional university computer engineering and upfront paid bootcamp sectors.

Will it make enemies with professional regulatory bodies who may be biased to prefer higher education hurdles and fewer licensed practitioners to protect their income?
