It doesn't! That's the whole point I'm trying to make (poorly).

People are not hating that (existing, popular, but unnamed here to avoid distraction) language because in practice that problem doesn't bother people at the same level that it bothers with C/C++! Why? Because the compiler is not actively exploiting each bad step you make.

I think this is one of the reasons why discussing undefined behaviour is so confusing. From a technical/purist point of view, it clearly means something and once the behaviour is undefined, it is undefined and yadda yadda.
But in practice it makes a huge difference, to the point that people tried to coin a new name for it (e.g. "unsafe code"), while it is the same thing.
H2O turns into a sort of gravity-propelled fluid form known as "rain", and then its greenhouse effect in the atmosphere ends quickly.
Yeah, divergence-free noise is definitely what you want to look into here. It should also help with the particles collecting into strings like in your tests.
To be a bit more precise, Google didn't provide all the information regarding their earning based on copyrighted content they display on their platform.
They also unilaterally decided to exclude part of the press and part of the copyroghted content from negotiations.
They also unilaterally made the negotiations specific to Google Showcase.
The antitrust regulator is fining Google because they consider that all this is a systematic strategy to cause negotiations to fail rather than comply to the EU directive of 2019.
> […] especially in the US where leave is not mandated.

Slightly meta, but I wish people would stop saying "the US" as if it's a monolith. It's not. It's a federation of smaller entities. It's saying "the EU" parental leave policy as a monolith: it's non-sensical.

The EU has a whole bunch of different countries which do their own thing, and the US has a whole bunch of states that do their own thing.

Just like people might compare Denmark versus Spain on weeks given, you have to compare (e.g.) Illinois to Oregon.

The EU as a whole has federalism, and so does the US.
I was really tuning in to the concepts but he completely lost me when all the examples used math and trigonometry.

I loathe teaching of programming through math and trig. I feel using math and trig to teach programming is a bigger barrier than anything else.
How about integrating/summing values? Seems like if we interpret the Perlin noise values as "how much to change" instead of an absolute value we would get the end result immediately.

However, it would be more difficult to determine a value just at a given point instead of walking first through all preceding points.
theres a limit for time (6 months?) for these via the website, and via the API theres a limit of 2000 or so latest comments, with no way to get the list of latest comments re-populated from older ones when your comments do get deleted. (They basically have a cassandra db for all the latest stuff, and an read only db for the old stuff. So the live db never gets updated from the old db.)

What this means is that your a lot of old comments and submissions are unable to be deleted.
With sufficient preparation I could pass any physics test without actually understanding physics. A Chinese room within the mind, if you prefer a philosophy reference.

Thinking about it, I really should’ve gone with that analogy first — it keeps this in the category of languages.
From the article, the fragment about the SF2 sidemount rebreather:

> There are only a few of these computer-controlled devices in the world.

From quick googling I found out that this type of rebreather is "certainly the most popular Sidemount rebreather in the world." [1]. It is relatively inexpensive also (7k EUR). Why are there only a few of them in the world then? Is he talking about some special, modified type of it?

I love Bret Victor's essays and talks, they are truly inspiring, including this one.

It's too a comprehensive and far reaching essay for me to comment on in general, but I have a few random thoughts to share:

Right at the first example what immediately came to mind is simply having a better API. It's a boring but effective solution to say fill(color(r,g,b)). It also teaches data abstraction which is a common and powerful concept in programming (and I think it was introduced in an early chapter in SICP as well).

Secondly I think there are not enough good tools that empower non-programmers (not full-time) to program. Programming literacy (to some degree) should be more widespread and I agree with the notion that it is a way of thinking rather than just mechanical.

For example Excel is a tool that has managed to democratize programming to a high degree. When I teach designers to code websites, there are some who have had some experience with Excel, and they typically have less of a problem to understand some of the programming basics.

On the other hand Excel is also terrible, because it hides relations behind cells. The broader concept of this is also criticized in this essay.

In essence we need to find useful abstraction layers between what is main stream programming and main stream GUIs. I know many are actually doing that with varying degrees of success. But I think we need to be much more playful and drawing from history and science rather than thinking in terms of products (to sell) if we want to reach the stated goals.
It's been a while since Reddit was a content aggregation site. Right now, Reddit is an ad delivery and data collection platform built around a content aggregation core, the way a mouse trap is built around a cheese cube.
Hello! Author here. Didn't expect to land on HN before the compiler is actually useful - Oto, you'll pay for this! :)

Feel free to ask me anything about the project, although bear with me - I'm learning compilers/... on the go, didn't study them or anything.
>poor people don't have access to healthcare, whereas everyone has access to vaccines.

You are answering to some argument that I didn't make.
Reddit is very enthusiastic about handing out site wide bans these days. If you say the wrong thing on the wrong topic you can be permanent banned, whereas before you would just be downvoted or argued with.

Same for subreddits being banned. But only when it comes to speech it seems, not picture or video. So, for example, we have the odd case of "truelesbians" subreddit being banned for being trans-exclusive, but "lesbians" subreddit which is also trans-exclusive, but dedicated to pornographic imagery, is allowed to stay.
I'm a fan of Kafka for streaming systems, so I'd recommend to fetch data via api, add it to kafka and then consume from kafka to monitor the price + fire alerts (assuming you don't really need a real-time system with very low latency).

What language you use is up to you/your team. If you like python, I'd look into Airflow or Celery as frameworks to build your workflows.

For java/scala I'd take a look at Google Dataflow or Flink or Kafka Streams, depending on how heavy the "monitor share prices" part is.

I think the major issue you're going to encounter is not building a system that works, but building a process that allows your team to upgrade the system, test new features, debug, etc.

Dataflow, for example, lets you run more or less the same code both on a stream of data and on batches of historical data.
But ultimately on Earth, even in the dry polar latitudes, there’s certainly enough water to absorb everything in the H2O spectrum lines. The atmosphere is lousy with water, generally 1-3%, meaning it is usually the third most abundant gas.
This is just increasing competition in the search space. Any new search engine who is growing big will also have to pay to just "link" another website. And in most cases not be able to afford it.

This is not how I imagine the internet to work :(

This was just lobbying done by newspapers who are dying to social media and better news channels.
That seems like clickbait.

They have a hypothesis that the observed stream of stars is from a globular cluster; and a hypothesis that the globular cluster contains/contained an unexpectedly-high number of black holes.

What is moving through the Milky Way is a stream of stars. They haven't caught anything, from my reading of the article at least.
>Maybe the solution is to add that amount of time to male paternity leave?

The MPA/RIAA are one of the greatest threats to the internet in general right now. They are constantly pushing for more and more power, making greater and greater demands of ISPs and hosting companies.

Even now that a global pandemic has demonstrated how essential internet access has become to our lives courts seem quite happy to insist that ISPs permanently ban people based on nothing more than unsubstantiated claims of copyright infringement.

They've turned the DMCA into an alternative revenue stream where they can shake down people (both the innocent and the naive) who are forced to hand over settlement money for protection because they most often couldn't afford an attorney for advice let alone afford one for a long battle against media giants in courts that have increasingly become pay to win.

It's frightening how much they've managed to get away with already. I used to worry about how much of our culture they were taking from us, now I worry about them taking things much more fundamental.
That was an anticlimactic spinner. I guess if you are going to post on HN you better make sure you can handle more than 1 request concurrently?

Reddit hosted videos have been such a joke lately. They are just ripped from YouTube and TikTok, almost always with out the creators permission.
It used to be that your customers were supposed to like or respect you. Now we have a growing number of companies with customers that actively dislike them, just waiting for a better alternative so they can jump ship. It is a problem with monopolies.
Or, maybe, force businesses to pay for this benefit themselves as a recognition that it’s workers are human, and having a family is an important piece of a stable life.
Lachlan Morton completes 5,510km Alt Tour, beating peloton to Paris by five days
One thing to note is that writing the compiler in Elm instead of just compiling the Haskell compiler to JS allows us to expose bits of the compiler as an Elm library.

I mean, being able to bootstrap is nice and nerdy and so on, but I believe exposing the parser, optimizer, type inference etc. as standalone functions will be the most impactful aspect of the repo, in terms of enabling better tooling in the Elm ecosystem.
80% of the videos on Reddit are from TikTok anyway so might as well just get them from the source and skip Reddit altogether
DevOps hosting solution Try for free
A lot of countries have the technological capability to manufacture mRNA vaccines with open licensing. However those aren't the only options, and even developing countries can make vaccines like the AZ and J&J ones as evidenced by some of the existing outsourced production. What's lacking is the legal right to do so.

This also should be a global engineering effort with technology transfer and an active effort to open up COVID vaccine manufacturing wherever possible.
Wood gas was really common and used to power all kinds of lighting before electrification. FEMA even created and distributed plans[0] for a Gasifier in the late 80's. You can find the PDF all over the internet, I think its a pretty cool looking project.

Youtube is full of weird wood gas car projects such as this pickup truck:

I've always found this advice confusing and contradicting. Higher level to lower level doesn't read like a book. To make it read like a book (or an essay), you have to "flatten the tree", do something like:

void get_opinion_of_uncle_bob() { prepare_mind(); opinion my_opinion = get_opinion(UNCLE_BOB); return my_opinion; }

void prepare_mind() { get_coffee(); sit(); }

void get_coffee() { / ... / }

void sit() { place(butt, seat); }

void place(auto object_to_place, auto to_be_placed_on) { move_away_from_obstacles(where_to_place); put_object_on(to_place, to_be_placed_on); }

void move_away_from_obstacles(auto what_to_move_away) { / .... / }

void get_opinion(int on_whom) { / .... / if (on_whom == UNCLE_BOB) { return create_opinion("too many short functions"); } }

Well, it's just a pay band. The explanations are post-hoc, because you can't get promoted by following them or anything. You are supposed to live up to them at performance review time, and how that works is different at different companies.
That's not the case here at all, it's about Google taking revenue away from newspapers, and when one messes with another's source of income, things come to a head. Looks like you're in the wrong part of the town. Are you lost? Would you like directions?
Most news is nothing more than the headline and even if there's more to it, it's a known problem that people are not reading the article.

Just the headlines create a business for many, like the forums or search engines. You need only the headline to stimulate engagement and show ads but that headline often is generated through the work of many people that are not the beneficiary of that engagement and ad business.

If the headline had no IP value, Google and others would have been generating them without actual connection to reality instead of fetching them from those who send paid employees for on site observations to gather information that would be evaluated and the converted into a headline/title .

I don't say that the French approach is the correct one but obviously the alternative is also not problem free.
> What source are you quoting there? I can find that line in an abc news feed, but no attribution and nothing much else about it. Every other source seems to be talking about inflammation of one sort or another (myocarditis or pericarditis), primarily in young men, very rarely and easily recoverable.

I cannot find the source where I found it first, but that could be the case that they confused the two, I am not sure. Some are talking about hypertrophic cardiomyopathy. In any case, it can lead to chronically enlarged heart, which is dilated cardiomyopathy. Whatever.

> We are learning all the time, that's true, but these side effects are very rare, and are becoming visible due to the large scale of the rollout. It doesn't fundamentally change the calculus, especially when we are now learning that the disease itself can cause lasting lung and brain damage.

I suppose continuing discussing this is not very useful. If there are long-term side-effects, then we will know about them. If there are no long-term side-effects, same story.

By that you mean you'd have to have read the article and interpreted in the manner by which the HN AI has accepted, right?

HN is often accused of being a 'hive mind' of users with homogenous opinions already. Making people assert that they've read the article, and understood it within a set of constraints, could remove a lot of nuance and variation.

Plus, I hardly ever read the articles.
Yes, of course the possibility is there, but it needs a huge leap of the imagination to even hypothesise what that short or long term adverse effect from mRNA vaccinations could be. Don't forget that coronaviruses are themselves "mRNA vaccines", with the significant difference that they actually reproduce, are contagious, and cause disease.

One could also argue that there's the possibility that SARS-CoV-2 will trigger an epidemic of extreme early-onset Alzheimer's in people who are currently suffering from long COVID. I don't think this is likely either, but I would argue it's significantly more so than an abstract unknown unknown about mRNA vaccine side effects surfacing in the future.
Don't think that I don't understand the banal point you're trying to make.
> Feminism want us to believe that taking care of kids is a burden that men unfairly push to women while they go off to have fun at work. And huge parts of society have swallowed it.

No, the feminist position is that childcare is an activity that does not have to be done exclusively by the mother. And so there should be equal and generous time off available for both partners regardless of sex (or if a same-sex relationship, relation to child).

Of course there are biological considerations too. The mother having the opportunity to breastfeed, in particular. So the schedule of leave may be organized around optimizing for this as well.
If the headline being the valuable content is true, it suggests there could be a business that's like a newspaper that only publishes headlines without articles.

I'm not saying this to refute your comment! This might actually be a valid idea.
It's a reason why employers should encourage regular reasonably long holidays.as well. Stress testing failure modes in situations where you can plan ahead and can buy your way out of a crisis is better than finding out in circumstances where you can't.
So, add "search for the existing link first" to the list of steps of the supposed "convenient" method. These arguments that "oh its more convenient for me anyway" do not got very far, specially when i claim its the virical advertising that makes people think it is convenient.

> Then you’ll have to request multiple people who run services that backs up every reddit post.

> But that’s still way better than HN. At least on reddit you can easily delete posts and accounts.

This is a topic where the interests of the community and the needs of an individual come in conflict, and I don't think there's an universally agreed-on standard practice. By community I explicitly do not mean the platform that's hosting it, though they have interests desires too - just the collection of people reading and posting.

A deleted comment in the middle of a thread is often extremely disruptive, as everything below it in hierarchy (and other locations linking to it) loses crucial context. Being able to distance yourself from your comments (through deleting the account, and thus making the comments show a "deleted user" as author), but not to delete the comments themselves, balances these competing interests properly.

For HN per se, see https://news.ycombinator.com/item?id=23623799 for mod take on the topic.

> effectively the janitor's wage has to go down to cover for the risk the software engineer has kids.

Salaries are usually not a zero-sum game.

Having kids is a full time job. When you get kids you can kiss all your free time goodbye, say goodnight to the side projects. Having kids is not good for your career, or other life goals. And if you are alone, eg. you have to pay for everything yourself, it also means a life in poverty.

I never said I don't believe you. I just said there was nothing scientific in your reasoning. It's completely obvious that not all people get covid that are exposed to people. I've also been exposed to covid and not been infected. But it's just anecdotal information. I could get covid and die just the same. Drawing any conclusions off of these individual occurrence is not very intelligent.
