Considering how this thread started, you're saying that we need to escape to the one place that hasn't been corrupted by capitalism?

But more pragmatically, neither Biosphere project was considered successful enough to make this workable on earth at any large, or even small, scale. There is still much more work and research to do here. Any attempt here currently has a hard dependency on the larger ecosystem to supply it with inputs.

Musk working on building moonbases on earth looks a lot like what doomday preppers are already focused on.

Yet earlier in this thread, you were incredulous about even the possibility that a chess game state could be entered into software or communicated during play. Which is clearly a ludicrously blind statement. So pardon us if it's hard to be particularly impressed by, well, whatever you are impressed or not impressed by. Because you don't seem to have much grasp on the basics involved, here.
Wow that last bit seems like a rather important disclaimer that I didn't know about when this saga first unfolded.

> It’s the same thing with calculus. You’re not here because you’re going to use calculus in your everyday life. You’re here because calculus is weightlifting for your brain.

I doubt that there is no other ways (e.g. lower cost, more effective) to weightlift for your brain than learning calculus.

Also, the professor has a conflict of interest here (e.g. making calculus sound important because he teaches calculus). It's like me holding a shit coin and pumping it up, but yeah let's ignore that conflict of interest.
Does anyone know why you would choose a ducted engine design here? Why not a more traditional propellor?

Since the pipe organ will be inevitably mentioned in the comments, I'm gonna plug the Youtube channel ‘Look Mum No Computer’, whose gear-crazy author in now apparently in the final stages of installing and patching up an organ in his seemingly interminable basement, after moving it from someone else's house: https://youtube.com/shorts/XGL3rskcQD0

Said organ was built by its late owner not just in the house, but pretty much into the walls of the house, and as a result the thing had to be ripped out of there rather grotesquely, and then rewired again at the new place: https://youtube.com/watch?v=8PwwRR8deHk

Read through some of the comments here and there's great insight from various vantage points. What I haven't seen and would love to add is that taking a break from a hobby or activity (which may be achieved by jumping to something else end back) is very beneficial. Coming back with after a break leads to a different insight to said activity.

I'd say 100% developer churn is the real problem here, no inherited 100kloc codebase is going to be a walk in the park if the original devs are not around.

However, I do think that it harder to keep a large code base understandable when using a dynamic language v.s. a statically typed language.

Having problems with understanding the shape of expected data is certainly a problem experienced in larger Clojure code bases, I guess this is just a disadvantage of using Clojure.

Documentation, tests, spec/schema and good naming conventions can mitigate this disadvantage to some extent.

> The S&P opened at about 3618 yesterday (after closing Friday at a little under that)

I didn't think it was worth mentioning the numbers, because the change wasn't hugely significant for the S&P, but Friday close was 3589, Monday open was 3616; that is a rise of 0.7%.
I'm not entirely sure this is a good idea. But their removal of radar seems to have gone okay, so perhaps they've done their calibration tests and know this can be done.
That's cool. If rather stay with a more stable release.. Though as it is most of what I do is in docker and tend to stick with flatpak as much as possible. So limit my risk of breaks a bit.

There are a number of VTOL aircraft that have used multiple engines. The Yak-38 used two lift engines and one lift-cruise engine, the VJ101 used four lift-cruise engines and two lift engines, and the Do 31 used two lift-cruise engines and eight(!) lift engines. Out of these, only the Yak-38 was remotely successful, and not nearly as much as the single-engined Hawker Siddeley Harrier (and its derivatives).

There are plenty of ways to stabilize an aircraft without relying on pure engine thrust, and turbofan aircraft have some advantages here.

The distributed electric propulsion systems do have awesome redundancy, but they have significant losses in efficiency compared to fewer, larger props, which really isn't what you want in an aircraft with severe energy density limitations. I'm curious to see what the production Lillium's payload, range, and power margin end up being.
Given that most people will use their one and only router for this, it means most of these devices will have access to the internet. Sure, you _might_ be able to prevent it if you jump through hoops (because it really is annoying to setup a second wifi network, at least in my experience) and assuming the devices don't fail if they can't phone home (and we can be sure some will). But everyone is much safer overall if the "common standard used by most people" did not use wifi.
“Bingo!!” said the teacher. “It’s the same thing with calculus. You’re not here because you’re going to use calculus in your everyday life. You’re here because calculus is weightlifting for your brain.”

Total BS...

There are better ways to exercise your brain that will be many more times better than Calculus. This is HW so one that comes to mind is programming. But there are so many more. Here are a few, understanding and fixing a car, understanding music and playing music, art appreciation, literature and understanding the human condition and on and on. Recent research has shown that doing daily exercise is a great way to keep a healthy body and brain, rather than sitting on your butt learning a useless subject.

Yes, there are professions where Calculus is needed and there are people that truly enjoy math. Cool, take all the math you need and want to learn. You should take it.

Anyone that tells you that Calculus is a good way to exercise your brain is just trying to justify their job. Don't for a minute believe that it's the best way to use a limited resource like your time.

Source: Me, it took me 3 semesters of Calculus to figure out that it was useless to me and 90+% of the people that take any of it.

P.S. note: Many people disagree. Good, you should not take it as absolute truth. I guess my real point is that you should question whether you really need to take Calculus. Don't just take it blindly because you are told you should. You have other options.
The square cubed law argues in favor of something that is more energy dense by weight but less by volume right? You make the wings a little bigger and the surface area increases a lot less than the volume. There’s also the potential of enlarging the fuselage and storing some there too.

When NetBSD imported sqlite and sqlite3 into their base system that was a signal to me that SQLite is no-nonsense and reliable. That was many years ago, around 2011 I think. Not sure why SQLite is getting all the attention on HN lately. Usually more attention means more pressure to adopt so-called "modern" practices and other BS.

SQLite is interesting to me because like djb's software its author is not interested in copyrights.^1

1. https://cr.yp.to/publicdomain.html ^2

Here is how Hipp abandons his copyrights:

The author disclaims copyright to this source code. In place of a legal notice, here is a blessing:

May you do good and not evil.
May you find forgiveness for yourself and forgive others.
May you share freely, never taking more than you give.

Apparently this is not be enough to convince some folks they can use the code (maybe they really are doing evil), and so there is also a strange set of "reassurances" on the website:

https://sqlite.org/copyright.html

It seems that is still not enough and so there is actually an option to pay for a "license" to software that is in the public domain. Don't laugh.

https://sqlite.org/purchase/license

2. I seem to recall an open source OS project or two making a fuss about djb's software being public domain but perhaps I am remembering incorrectly.

> But your "facts" are "if I use the API wrong, it behaves wrong."

Kind of, yes. That is what memory safety is about, isn't it? If I look for definitions, I find for instance <https://hacks.mozilla.org/2019/01/fearless-security-memory-s...>, explaining it as:

> When we talk about building secure applications, we often focus on memory safety. Informally, this means that in all possible executions of a program, there is no access to invalid memory. Violations include:

> - use after free

> - null pointer dereference

> - using uninitialized memory

> - double free

> - buffer overflow

std::optional does not itself protect against using uninitialised memory, it merely provides the tools by which the programmer can prevent using uninitialised memory. Isn't that exactly what memory safety is about, about having std::optional somehow automatically ensure that that doesn't happen? If that isn't what memory safety is, what, in your opinion, does it mean instead?

Note that I have attempted to refrain from posting my opinion on whether C++ made the right call or not. That is a separate question from whether it qualifies as memory-safe.

> Why does his intent matter unless you think the data is being skewed or misrepresented?

Because the data can be cherry-picked, intentionally or un-intentionally, similar to https://xkcd.com/882/

If you believe a trend exists (or just want to find evidence for it for other reasons) and you keep looking for statistical evidence of it, you're going to find it.
> I'm sad to see this because we literally do use calculus every day of our lives. We just don't often recognize it. The weather report is made using calculus.

This is like claiming David Beckham uses advanced physics to kick his free kick.

Calculus is important to the world, sure. But it's not important to regular people to spend time and money learning it. In some cases, these people take out student loan to learn calculus which doesn't help them pay back the loan.

How to get social proof leverage and establish image?
Cold applications seem highly ineffective as the leverage is toward them as opposed to them coming to you. Someone once said it takes about 1000 applications at entry level. That's a lot of time with no guarantee of anything to show.

I'm asking here of elsewhere believing there is higher level thinking because looking up information on this topic seems parasitic. Snippet articles and videos void of content or experience (influencers), masquerading as insights, self promoting.

Something that is longer term thinking, maybe a year, perhaps organic traffic -- you have enough CVE, blog articles, talks, packages, or something somehow planned out -- perhaps something might be probable to work? What is a long term methodology, perhaps a year or more, to establish social proof for a technical role?

The notion of an "overheating" economy always sounded like nonsense to me.

Those figures are misleading because a great many people permanently left the work force during the pandemic and are not counted as unemployment.
Did the demand for products from polluting industry disappear in the developed world or did the factories just move overseas? Shifting blame to "underdeveloped and corrupt nations" does nothing to address the fact that developed countries still demand goods from polluting industry and do little to promote more sustainable forms of economic development.

Datetime is mostly there. I think firefox and safari have yet to implement <input type=month> and <input type=week>. As for combobox, <datalist id=mylist> and <input list=mylist> is supported everywhere. However I would like to see the CSSWG focus on better standards for styling these, it is possible now using a lot of vendor-specific hacks, but is really annoying.

I’m gonna go ahead though and declare frontend validation (as good as) finished. the constraint validation API is amazing to work with (if you are not afraid of intercepting the submit event using JavaScript).

We live in a very modest (manufactured, gasp!) home for our income, our "new" car is a decade old, with other vehicles ranging far older (the tractor is about 80), but still maintained in perfectly good condition and they all do exactly what we ask of them.

Is every form of industrialization, from the USSR to the UK to the US to China, capitalist?

Is the current energy transition, funded by massive amounts of capital, and the result of industrialization of technology, somehow less capitalistic?

Are the ESG efforts somehow less capitalist?

Sometimes, our mental frames are traps rather than tools for understanding the world. This essay makes me think that this person is quite trapped, unable to absorb or explain climate action of the past 30 years.

> Capitalism is a grow-or-die system. If accumulation declines, the result is economic crisis.

You know what else is grow-or-die? Life itself. All of life is a series of exponential growth, followed by slower growth. It's all logistic curves.

This idea that capitalism is all growth is a very simple-minded and inaccurate view of capitalism. It's also the death of firms. It's stagnation. Its fortunes squandered, in addition to fortunes built.

Don't get me wrong, I don't think that capitalism is the be-all end-all system, but these critiques are so weak as to block any chance at actually fixing the many many problems of capitalism.

I can't read this thing without thinking "really? Where is your critical thinking?" About every single paragraph.

Essays like this degrade the critique of capitalism into nonsense, ultimately weakening any attempt to change the system, because they discredit the idea that there are actually lots of legitimate critiques of the system. They also cheapen critique by broadening the definition to basically "what I don't like at any given moment."

There are some platforms that provide std::optional but not value()! macOS 10.13 is one of them. You're forced to use the unsafe * operator on that platform. I cannot imagine the rationale that went into shipping std::optional support without value(), but they did it.

I feel like the big companies have nothing to lose from saying and doing these things. First it frees them of any guilty conscience to hack and slash at 'extra fat', second it allows them to get away with running skeleton teams. Third, it makes people who get solicited and receive a job offer feel "lucky" that they were given an offer in a "bad market".

There's no reason for them to not act like this. Unless a pile of startups are standing around throwing more money at engineers and loudly attracting google's talent away.

While I generally agree to get parity you would use common sensory input, I would hope the goal is to go beyond human level and navigate in for e.g. fog conditions or heavy rain, etc. things radar would help with. Ultrasonics probably don’t buy them much at this point as long as they have good object permanence. Think about parking in a garage. If you can map objects to special memory adequately then maybe ultrasonics aren’t necessary. However if the object is out of sight out of mind, you probably need the ultrasonics to help not hit it.

I was very surprised indeed that my little bank accounts used to manage hundreds of euros were also suitable to manage millions, one I sold shares in a startup.

When we tell poorer countries to preserve wildlife we do this while we have eradicated all inconvenient wildlife in our own area.
Yes.

Finding out how to attribute a sale to specific features or marketing is definitively possible and common usage.

Finding out why customers churn and what levers could prevent that is also a very common practice.

But finding out why someone _didn't_ buy something in the first place because of a _missing_ feature is just plain and simply impossible.
