This is such a crazy way of thinking about Elon. What would this gain him exactly? Attention doesn't make money, attention doesn't help growth. And doing that now because attention would go away in a couple years makes zero sense.

Musk literally always does the same thing, he comes out, talks about a bunch of things he wants to do and then goes and does them as well as he can. He has done that for 20 years and yet still people come out with the 'Elon is doing 4D mega brain level marketing' every single time. Even when he is wrong he goes out and does it anyway until he is forced to correct course.

Elon in fact does believe that by 2030 he will sell 20 million cars, and he most certainty is not content with being a 'smaller minority part of the industry'. Did he stop when he managed to get Falcon 1 to orbit and make a nice buissness out of that? No, he went on to the next bigger thing. The same thing for the Falcon 9 transition to Starship.

What makes much more sense is that they wanted to show of the level of technology they have an recruit more people to this effort. They also want to light a fire under the competition ass and show the people how the ICE age is ending. Literally the exact same thing they did with the Gigafactory in Nevada, when people said 'oh he wants to create the biggest battery factory in the world, that is pure hype and marketing' and now they have the biggest battery factory in the world.
This is me too and sometimes I feel like the language is going in two directions. The academic / scholar path where people show off unreadable C++ like this and the business path where professionals that use a subset of the language (mandated by corporate code base or teams) that are competent C++ developers but maybe not writing this complicated C++.
the question of trust is the wrong question to ask imo. the bigger threat is unmaintained packages and maintainers that themselves use risky code management practices (e.g., lack of 2fa on npm). that a dependency is heavily relied on does not mean its maintainer is following best practices security-wise or that they arent just as susceptible to social engineering as anyone else.
The assumption of uniformity is necessary to disprove a hypothesis. Otherwise, I could say, "You haven't refuted me; you just live in a different universe." (Sometimes it seems like they do.)
Don't the trucks typically haul propane? Natural gas is impractical to store at home because it's only liquid at cryogenic temperatures.
> Because of all the browsers they have led the way in reducing the ability for advertisers to track you.

Certainly when compared to Chrome, but Firefox? Brave? Tor Browser? No. Which is why it's so unfortunate that you can't get a real third party browser for iOS.
In the same vein, justice isn't being done any favours by pretending that 'embarassing the US' isn't the real reason why he's on trial.
Just as I feared, the government has abused so-called "emergency measures" to exert an unprecedented level of control over Americans' lives. Give an inch and they'll take a mile.
Polaco Goyeneche is that you?
While sampling equally from different income groups might clear up these variables, from what I've been able to find some of highest rates of dementia are in relatively small rich European countries.

Those countries have longer life expectancies so it's hard to do apples-to-apples for rich countries to poor countries.

I do think the "use it or lose it" model for neurodegeneration makes a lot of sense, in the same way you lose muscles if you don't use them, so bilingual is an interesting proxy for greater brain use. Although I also think the lack-of-sleep model makes sense too so I really don't know.
This looks fantastic. I was recently reading a config file from Rust and ended up going with JSON5 but this is simpler to read. In a language like Rust you don't need the types because you specify that in the struct anyways. Sure, this means that there are effectively more types than strings but the user doesn't need to differentiate.

In Rust you do something like this:

#[derive(Clone,serde::Deserialize)]
struct {
an_int: u64,
a_float: float,
ordered_map: linked_hash_map::LinkedHashMap<String, chrono::DateTime<chrono::Utc>>,
unordered_map: std::collections::HashMap<i32, String>,
}

So there is no need to worry about if maps are ordered or if a value is an integer, real or string in the format itself. Ironically for Python (which the reference implementation is in) it does seem much more annoying to have to manually call `int()` on each element.

I'm just a little sad that tabs are disallowed. I really think the best rule for indentation-sensitive languages is that each line must either have the same indentation in which case it is the same level, same indentation plus any amount in which case it is the next level, or the exact indentation of any previous level in which case it is a dedent. These "solutions" which just forbid tabs are half-assed and ones that try to convert tabs to a set amount of spaces just lead to confusion.

Additionally it would be nice if there was an example of a dict inside a list. I think it would work like the following but can't confirm from reading the site.

-
key: value
-
key: value
other-key: other-value
I think the parent’s point is that if you’re going to allow backup codes you might as well just add “second password” as a form of 2FA and enforce some basic complexity requirements.
I love Python, and it's my first and most-used language, but I definitely agree. I want something that takes the best parts of Python, is compatible with most existing Python code, and has a much better tooling ecosystem and better options for static typing.

Spending a bit of time with Rust's tooling, static analysis, and "if it compiles it's pretty likely to work" (at least way more so than with Python) definitely emphasizes a lot of Python's flaws.
If you look elsewhere in the comments here they are often for sale. At some point however, the cost of renovations outweighs the benefit. Especially because the larger the ship the more profitable it is, and these ships are being retired for ones that hold up to 4 times as many people and are 50% longer.
Keeping information from the public to avoid mass hysteria is one thing, but keeping information from hospitals so they don’t have to implement prohibitive protocols is daft. If the healthcare response would be unreasonable, the right thing to do is to deliberately modify the protocols, not pretend the problem isn’t happening.
I would much prefer people know the scale of these numbers than know big O notation. The number of times I've seen big O used as a hammer because everything looks like a nail can be frustrating.

This is doubly true on embedded systems where N > 3000 tends to be the less common case. Most of the time when I do performance profiles it's a 'flat profile' because the majority of the time is lost thrashing the L1/L2 cache.
It's briefly confusing if you have only lived in places with vertical traffic lights, and then move to someplace that has horizontal traffic lights, and vice versa.
Bourne Shell is a clear influence on Perl and PHP. And by the way, Bourne Shell was a influenced by C.

With the naked eye, stars can be seen to have subtly-different colors. Other commenters have pointed out that Mars is rather distinctly orange/red, and easily visible in the skies of North America now.

One example between stars right now is the two brightest stars in the constellation Orion. Where I am, in Indiana, USA, Orion rises around midnight EDT (~0400 UTC) tonight. It will rise earlier is you are east of me, and will rise earlier as we get into northern-hemisphere winter.

Betelgeuse (pronounced like the movie "Beetlejuice", but with "bay" instead of "bee") is Orion's right shoulder. Since he is facing towards us, it is the star in the top-left of the constellation. Betelgeuse is a red supergiant, so it is both distinctly bright and distinctly red when compared to the other stars in Orion.

The star I like to compare Betelgeuse to is Rigel, Orion's left knee (bottom-right from our point of view).Rigel is a blue supergiant, similarly bright to Betelgeuse.

Here's an excellent color-enhanced mosaic image of the constellation by Rogelio Bernal Andreo, which clearly shows the red-orange-ness of Betelgeuse compared to the other stars in the constellation:

https://upload.wikimedia.org/wikipedia/commons/4/47/Orion_He...

More information about the image can be found here:

https://apod.nasa.gov/apod/ap101023.html

To the naked eye, I (and other typically-sighted people) can distinguish these colors easily when looking for them. Their color ranges from red/orange to white to sort of sky-blue. This is because starlight is black-body radiation, which creates a very specific scale of colors. Here is an image showing the typical colors of stars, and their corresponding surface temperatures:

https://en.wikipedia.org/wiki/Black-body_radiation#/media/Fi...

Rest assured that to me, at a glance, stars are just bright white dots. Even knowing that the colors are there, I still have to stop for a second and look at them in order to see it.
no. for the love of God no. please stop already
The reason we have stuck with it ever since it s because it's a decent cutoff. I think in physics they sometimes use a much higher threshold of 5 sigma. Presumably because having much more data means they can afford to.
To add to your suggestions: avoid referring to colors on a chart by name. While it may be able to identify the difference between two colors (e.g. by intensity), it may not be possible to identify the color. In my case, identifying blue and purple are frequently difficult. Presumably this is because purple is a mixture of blue and red.
Intel was shipping 4-core desktop/laptop CPUs for years when they could have had 10-12 cores. They were definitely sandbagging until AMD forced their hand.
If the only phishing protection you find meaningful for 2FA tokens is domain matching then any extension-based password manager like Bitwarden will work with far less hassle than needing a physical token or your phone.
You are right. It mattered when I was applying for jobs as a fresh grad. But it no longer matters. On the other hand, I still remember lots of the ideas behind theorems though I haven't done any pure math in a long time. While most of the people I know can't remember what a vector space is anymore despite high grades. Universities need to cut down the number of exams and let kids have sometime to think and try things out. When you have competitive quizzes every two weeks whole life revolves around them. Professors used tell us that those frequent quizzes were there to help us spread the eggs in multiple baskets so that our grades didnt depend on just one exam. I think they missed the point that I wasn't there for their exam grades in the first place. Well.
This is not what I said.
I don’t think that’s it. I used syntax highlighting for nearly 20 years then stopped a decade ago and don’t miss it at all. So I had every reason to want to use it but now I don’t even want it.
I stopped loving Rotten Tomatoes after it was purchased by Comcast/Universal Studios and Time Warner/Warner Bros Studios.
Well, there's nothing about the JSON spec that says you can't serialize 64-bit integers to JSON. The grammar allows unlimited precision. Implementations may vary.
Fact of the matter is there's nothing too scary about living in China as long as you are not involved in politics. The scary thing about a BJP lead authoritarian regime is that unlike the CCP, BJP is made of a bunch of idiots. CCP is authoritarian, but they have made sure every Chinese has food on the table, a roof on their head and one can live an honest life in China without having to be corrupt. Crime rates in China are fairly low and one can walk on the street in the middle of the night without living in fear of lynching or raping. This is not true of India. Even doing simple things requires you to have connections or pay bribes.

Additionally, CCP actually thinks through its policies whereas BJP rolls a policy out and then does a 180 degree turn. Just look at the COVID-19 epidemic. China actually managed to end it because it was authoritarian (even if you don't believe the CCP's numbers you cannot deny that they have managed the situation far better than a lot of other governments). BJP had the opportunity to do so but somewhere along the way decided that they could just follow Trump.
Yet, other languages are, also, only just getting similar features.

The author seems to prefer to mention languages that are still taught and used, and to neglect those that are not. It being an "opinionated" history, I can only find fault where he breaks his own rules. Maybe he should mention Korn shell, for example, which became Posix shell and bash. But only Bourne shell features affected modern languages.
XML is fatally flawed because you can't safely put one XML doc inside another one. Because of this rather fundamental problem, it never was any good for anything, and it never will be.
I don’t really care about this one too much because if you got a copy of my pw database and knew the password you have enough access to remove the 2FA on my stuff.

Like there is literally 0% chance I’m going to let myself get permanently locked out of my accounts if my keys and phone get stolen.
‘The Man Who Ate Too Much’ Review: American Appetite

It affect people differently. It makes me much more attentive and able to listen to what my wife has to say. She has been very happy with the effects.
The numbers and math all look correct but some of the comparisons seem to be cherry-picked. Titans weren't included but the 3090 was for example.
That obviously depends on which governments and what the governments do.

A US antitrust ruling that Apple can't constrain the user from installing apps from competing stores while Apple is still selling the device and not loading it up with crapware by default is very different than a requirement from China or India to install the government's store as root on everybody's phone from the factory.

The difference being that you choose which stores you trust instead of having them imposed on you against your will.
Yeah that would be ideal but that's much harder for the people doing the study than just picking an age.
So, um, did SF just permanently end their commercial real-estate market?

Add this to the other interesting government initiatives launched in CA this week and you have to wonder why all businesses are not flocking to relocate to CA.
That was the right question. Fintech. Previously, data communications. Those numbers are etched into my cranium.

There is lots of programming that is not performance-sensitive, but I don't do it, or hire for it.
Is it just me or NestedText is kinda subset of YAML? I personally see very little advantage of using this over json or yaml, but having more flavors and variation is always a good thing.

Edit: forgot to mention. I personally don’t like most general data serialization formats for configuration, the one I can probably tolerate is XML, but even that I only use when it’s part of requirement.
The way I usually implement program behavior configuration is through runcommands(runcom, .rc)
Great. I'm always open to being proved wrong.

Any chance of JS being mostly Babel free by next year ?

>If you dont have privacy, you cannot do anything as a group or individual that goes against anyone powerful. Freedom can also be thought of as sovereignty.

Seems like a pretty one-sided American cowboy version of freedom.

More accurate take I think is that privacy is often a tool of the powerful stopping collective action of citizens. Finance, taxes, and payment compensation are a pretty trivial example. The rich and powerful love their financial privacy, ordinary citizens gain little from it. Wage earners who benefit from their status love that they don't have to share their income with coworkers who may be discriminated against.

I think the opposite is true. It's not privacy but transparency that is required if groups are supposed to be able to take action against the powerful.
I like this quite a bit. Keep stringly-typed text files as strings; let code sort it out.

Pydantic would work great in conjunction with this to coerce types.
>Does it even matter?

Yes, most tools are cross platform (not necessarily cross-arch but that's a matter of time) and performance is important - I don't care if it's Apple silicon or Intel or AMD, or what OS GUI I'm using - I just want faster builds and iteration

I've been using a weekly food delivery service this year, and lugging heavy gel packs to the trash was getting pretty tedious. They recently switched to a different brand of gel that claims to be "100% drain safe", so I can ship the mass away without going outside.

Are there other forms of waste that could benefit from liquid disposal? For example, I once received a package with water-soluble packing peanuts.
This culture of deceit needs to change. I don’t blame anybody for not following the rules.
Hugo is a single executable - it doesn't require any knowledge of Go itself. Granted, you have to be familiar with the templating syntax to add build-time logic to the website, but I believe that syntax is common across many other static site generators as well.

Yes, if you want to add logic in addition to the templating primitives provided by default, then being able to write code into the source pages will be of great help. However I think that when such a level of dynamism is required, then one can start debating the utility of a static generator in the first place.
Consider that the constant blaming of forest management is actually a tactic from the right to prolong denial of climate change by their voting base. Yes it helps, no it isn't going to do that much when California fire seasons have extended over 2 months due to climate change.
How does Go performance compare to Scala in large projects?

I’ve written small amounts of each.

Scala 3 will make Scala a nicer language.

Go was nice with fast compiles and not needing the JVM.

America has that story, but it doesn't really hold up to scrutiny. America may not have "class" restrictions like other places, but it sure does have "race" restrictions.

Ask HN: Why are we not using magnets for PTO coupling?
I don’t know if anyone here can answer this query for me. But going to ask anyways.. I spent 6 hours today trying to uncouple and fix 4-5 of my different tractor implements to a small tractor PTO spline.

It’s ridiculous and primitive. And one can only do this with brute strength.

I am not an engineer or a mechanic or know anything remotely automobile related, but I have few questions

1. Why not use powerful magnets to ‘guide’ PTO shaft to the splines?

2. Can it be done with some kind of laser guidance ..like a laser light(think like a low cost cat toy not high tech)

I am exhausted, hurting, smelly, sunburnt and greasy all over and I didn’t even get to attach all of my machines’ implements. I am flabbergasted by the primitiveness of this necessary task of swapping implements.

Any hacks or thoughts or advice?
Seems to me this regulation will have two very predictable outcomes:

1) For companies who want employee proximity, the companies will flee San Francisco
2) For companies who remain, the employees will flee San Francisco

Given that climate change is lower on a per capita basis the higher the population density and the economies of scale it offers, it seems this bill will have the exact opposite effect as to its intent.
I like Hugo. I've been using it since 0.17. I've forgotten if I found getting started with it easy or hard. But since then it has been a relatively smooth ride. No node or javascript baggage, fast build times, single executable - what is not to like?
Headline is wrong, it's not San Francisco. From the NBCNews report:

> Metropolitan Transportation Commission, a regional government agency in the San Francisco Bay Area, voted Wednesday to move forward with a proposal to require people at large, office-based companies to work from home three days a week as a way to slash greenhouse gas emissions from car commutes.
Unfortunately, you can't take an 50-something english only American and tell him to "go learn Italian", for health. It's hard enough to make people eat less, exercise, or quit smoking - picking up new language without another motivation than "for health" is going to be even harder.

Most schools introduce more languages today, no ? And I guess there is no motivation to keep language skills active beyond school, so any skill here will likely atrophy like me French :(
Great idea the only problem is preventing the fire from getting out of control. As we haven't been doing we can't just start tomorrow as they will turn into the fires we have today.

Doesn't mean we shouldn't still use prescribed burns; we should. Just smaller burns with proper protection to ensure the fire is under control.
Juji-io/datalevin: A simple, fast and durable Datalog database
Can you explain how N=27 could possibly represent and be extended to billions of humans? It is certainly not intuitive to me.
Exactly. If you don't connect your smart TV to your home Wifi network, it can't connect to anything and exfiltrate your data. I doubt manufacturers are secretly putting LTE modems inside TVs.
