I think you’ve misinterpreted my point, I agreed with the point your making about complex supply chains and components. I specifically said that its only going to make sense for some specific items, and I was specifically thinking the first candidate would be bulk low density support structures. For all the structural aluminium isogrid beams, and perovskite solar panels that are the end products of specialist supply chains with the exact issues your talking about

In a large scale on orbit construction project, like a space based solar power station, we could manufacture complex interlocking units on the ground like space station modules on the ISS, and hope all the power routing, and docking, and everything else, will work together when launched… or we can build it the old fashioned way, but with robots or astronauts up in space… bolting, welding, wiring, cabling and routing everything up there from easily made standard parts that meet the requirements. Just like large photovoltaic solar farms are built on earth, with X units of photovoltaic panels, attached to structural support frames suitable for the location they are being installed at (wind loads, thermal range, etc) … and everything cabled together with hundreds of little plastic clips and miles of copper wire in weatherproof plastic conduit.

Now some things will obviously be different in space, like hundreds of plastic clips are obviously a space debris risk, so they probably won’t design cabling systems that need that sort of support. But they will need to manage lots of power and data cables which will need some level of protection from the slow but steady degradation by various forms of radiation and plasma from the Sun and deep space, and it turns out a few millimeters of plastic can get you years and years of protection from oxygen plasma which would could eat away at exposed wires and slowly increase the risk of short circuits. Yes it might need to be replaced regularly, but so will other things, and then you don’t need to use crazy specialised oxygen plasma resistant wire insulation…

Space is hard, but we build things for way more harsh environmental conditions on the ground all the time in industrial applications. What they don’t need that space currently does, is earth based industry doesn’t usually care about total weight. Starship will revolutionise space not by magic, but by slashing the cost per kilo and allowing us to use more normal engineering procedures and hardware where appropriate. Like panels and wiring and support structural girders. My point was that 3d printing lightweight plastic structural parts where they are needed, will be to space based solar power, what mixing concrete on a construction site is when compared to having everything transported to the site via cement mixers. Sometimes it makes sense for the project to mix on site, other times it won’t.

I’m not sure what there is to argue with about this thesis.
My motorcycle helmet visor says otherwise. Rarely don't ever have them smeared all over, even on a shorter ride.

> The following has been added to Kip Thorne's Preface in the current ("New Millennium") edition of The Feynman Lectures on Physics:

>> Note added 13 May, 2022: In addition to Caltech professors who contributed to the making of FLP, a number of graduate students and staff helped with the technical details of its preparation. The Forewords written by Feynman's coauthors Leighton and Sands acknowledge these helpers, but while Volumes II and III give lists, Volume I includes only a general acknowledgment. After consulting knowledgeable colleagues I have constructed the following, likely incomplete, list of people who, I believe, deserve credit for their help with the technical details of preparing Volume I: Alan Title, Marylou Clayton, Julie Curcio, Don Groom, James Hartle, Tom Harvey, Fanny Warren, Clyde Zaidins, and Barbara Zimmerman. (I would welcome suggestions for additions or corrections to this list; please send them to me at Caltech.)
This addition already appears in the online edition of FLP, and will appear in print starting with the next printing of FLP, which is currently underway.

That would mean that the reviewer understood the topic and was capable of writing a proper critique? I'm a book lover who reads a lot of fiction and non-fiction and more often than not in the last few years I have the feeling that many reviews are generated by people who read a different book, or didn't understand the one the comment at all.
Amazon is full of fake/generated/auto translated books in every category. Just search for any programming language and sort it by release date.

I don't understand why they don't fix this problem.
It's pretty easy to fix and all those sales don't generate a significant amount of revenue for Amazon considering the negative experience for clients.

Such books are pretty easy to spot since the majority of reviews are written by people who have published more than hundreds of reviews.
10,000? Could it be 100,000?

I have to write 10,000 words overnight occasionally in my role.

If it’s $2500 for 10k words, maybe I should be ghostwriting…
Reads like a composite. What's the origin of the plastic substance replacing the lignin?
Aren't those just nitpicky details, though?

When I was going to the office I'd usually get up, bathroom, clothes, out the door (I'm a shower-at-night person). Alarm clock at 7:30 when I need to leave at 7:40 wasn't uncommon. Sure, there's the commute but I don't think it's THAT different from what the author described, because I still take these 10 minutes before work now.

I mean, I contrast this with people who like/have to get up way before they strictly need to, to go for a walk, or running, or reading, or whatever. I hate that, I don't even drink coffee at home before leaving.
One heck of a pour if you're tipping $14 on a $6 beer.
> I soon discovered that all the books leaned on the same central argument: value is an inherent consequence of scarcity. My rebuttal to that was simple: it’s an exception, not a rule. My kids’ doodles are scarce, but in a gallery, they wouldn’t fetch much. Alas, while this made for a solid Twitter quip, it wasn’t enough for an in-depth post.

Scarcity in economics refers to when the demand for a resource is greater than the supply of that resource. Your kids doodles aren't scarce because there is no demand for them.

How did the author read 11 books on NFT's and not know this lol? The books must have been all very bad or the article author just skimmed thru them.

Interesting article other than that tho.
That's indeed what they tried to say, but they translated it very Dunglish.

We can't bootstrap a transition to renewables without fossil fuels and petroleum byproducts. In the short term, we might even have to accept missing emissions targets in order to build infrastructure and production facilities that will support green energy. So until we reach the point where we can rely on green energy to produce more green energy, and have viable substitutes for the thousands of ways petroleum products are used on industry, oil and gas workers will still be needed to keep our economy running.

Looks like I can still edit the title. Care to make a suggestion how to phrase it?
I'm surprised that nobody asked- what for? what is the purpose of this server and why should it last for 20+ years?
To everyone replying “aerodynamics”, I’ve had the same car for about 9 years now and the drive along the 5 from Bay Area to LA feels like there’s fewer bugs on my windshield (granted not recorded diligently for scientific purposes but whereas before I’d need to scrub the windshield at least once halfway these days I can drive all the way and still don’t need a wash at the end)

Same goes for the argument that bugs have evolved to migrate away from the roads - the 5 has been a busy thruway for a long time with lots of cars and trucks.

The article is short but says scientists have clear data that populations have plummeted and the larger vehicle consumer trend + more people on the road means that there’s fewer bugs to encounter per windshield on top of that.
I can attest that. I drive a Land Rover Defender which, you know, has the aerodynamics of a wall. It's full of bugs after driving on the highway for more than 30 minutes.
When the topic of school comes up on HN, there’s always a few people who believe that the school environment is in fact detrimental to children and everybody would be better off home-schooled with remote learning to fill the gaps.

Does this result provide enough evidence to the contrary, or was the pandemic too much of a special circumstance?
There are many wonderful tools that help understand what our code is doing (compiler explorer, gdb, valgrind, ftrace, perf record, strace, ASAN/UBSAN). I wrote this blog post because using the debugging tools with Cosmopolitan Libc helped me learn and improve at programming. If you have other resources that can help me understand more about how my code works, I am happy to learn.
Interestingly enough, the article itself discusses aerodynamics.
this is why 2+2 should be 5 so that kids can pass increasing the schores.
I think DRM for monthly subscriptions is fine. You pay X amount a month and you get access to the service while you pay and lose access if you stop paying. That's the deal you pay for, which is clear and obvious to anyone.

I don't think DRM is necessarily and it just seems like an unnecessary hassle, but unlike things that you actually bought a perpetual license to (DVDs, CDs, games, etc.) it's really not that big of a deal.
How do you feel about the rebuttal to this claim in the article? Particularly the decline in licence plate splats?
Thank you for the reminder on swallowing on pride.

"Photoshop for text" was the title of a HN post here just a few days
ago. Many commenters delighted at the idea of being able to highlight
a passage, pull down a menu and "Rewrite Style -> Ernest Hemingway".

Nice people generally only see the immediate utility of a tool in
front of them. It takes a certain mind-set to see the other
"weaponised" implications.
Rust's answer here would be yes. The code which made this possible is faulty.

For example, you can trivially reintroduce C-style undefined behaviour on buffer overflow by writing a Rust type which implements Index (and optionally IndexMut) using unsafe to just not bother with a bounds check. Rust says this type is wrong, it should not do this, that's a bug -- even if your program using it has no buffer mistakes, the type is wrong anyway.

This is a fact of Rust's culture rather than a technical implication of the Rust language design, albeit they're closely related.

My second favorite tape is Honda's spicy rodent deterrent tape. It's made in Japan with capsaicin. It's not cheap, but much cheaper than an wiring repair at an auto shop*. The lowest price I was able to find seemed be be a dealer in Colorado … until I created an account, went through the order and saw the ~$20 S&H. The best deal including shipping was from the same dealer on eBay — no S&H charge.

Rats chewed through wiring in my car on two occasions. Both occasions were in cold weather and the chewed wires were above shelf-like spots in the engine compartment. One was a transmission solenoid wire and the other was the ignition wire in the main harness above the wheel well. In both cases I was able to self-repair by popping the pins out of the wiring connectors and soldering new leads (pig tails) to the pins. YouTube has several videos explaining the process.

When I first learned of FP about 20 years ago I thought it was a terrible idea. But I've convinced myself I have been proven wrong time and time again.

I still think sometime it's complexity for its own sake. Eg. why is it so hard to define a monad? But I enjoyed parts of Scala 2 and later Rust. There are good ideas in FP that lead to programs that are easier to reason about and manage complexity. Languages are borrowing these good ideas and I'm happier for it, algebraic data types, pattern matching and destructuring, result/either, immutability, etc
It seems the only official native API for getting the parent directory from a known (full) path is PathCchRemoveFileSpec. But certainly C# and other similar platforms have functions doing similar things, and usually don't require a system API call anyway, it's just string manipulation - unless of course the path is relative to the current directory.

Without DRM support much less people would use firefox because they actually want to use the netflix and prime subscriptions.

As I haven’t seen other websites than such movie streaming sites using DRM, I don’t think it’s another mail in the coffin. It doesn’t actively hurt anyone, and it does not stop shows to be ripped and released on tpb. It’s just an alibi for movie makers.

So, what’s the fuss about it?

It does nothing to stop accessibility at least. Doesn't prevent zoom nor break 'reader mode'. I much prefer when sites don't try at all to get mobile working and letting reader mode work than when they do something that breaks it. In reader mode I can customize the colors/fonts to make it readable for me and not be at the mercy of the designer.

I'm on Android, but I suspect iOS has something similar.
As someone who to some degree falls in the category you describe, I'd say you are potentially misunderstanding the argument.

I certainly wouldn't argue that spending time in a public school math class correlates negatively with math learning. I have no doubt that some math education takes place in public school math classes.

I think the argument is that it doesn't do a great job teaching most students most of the time while simultaneously having serious issues like requiring young children to sit still for extended stretches and punishing kids who aren't well suited to this.

I'm not saying that's the whole argument, just an example

It seems that you have not even bothered to skim the article...
The article discusses this at length, concluding that it is not a major factor.
I doubt that desire for cultural differentiation is going to change much about the diglossic situation in Taiwan, since the continued use of Traditional Chinese characters is already a pretty big differentiator. The government is making some effort to promote the Tai-lô writing system (e.g. https://tailo.moe.edu.tw/index.php ), but overall there's very little incentive for Hokkien speakers to become literate in it. If you look at Wikipedia visits from Taiwan, 92% go to the Mandarin version, 6% to English, 1% to Japanese, and Hokkien is in the tail of small languages behind even Cantonese and Classical Chinese. Of these, I think English is most likely to grow in the future.

Also, the differentiation potential is somewhat limited due to the fact that the majority of Hokkien speakers lives in Fujian province on the mainland (Hokkien = Fujian) and there's some preservation work going on there as well. E.g. Xiamen University's Speech Lab had a working demo of spoken-Hokkien-to-written-Mandarin translation in 2018, although the link shortener they used has since suffered from link rot. https://speech.xmu.edu.cn/2018/1215/c18169a359542/page.htm
The crazy thing to me is that the overhead of all this bookkeeping and extra hardware complexity adds up to less than the performance improvement.
Most modern civilisations have grown out of agrarian ones, where this is a fair prejudice.
This is the first I've heard of such a position. But I do think that remote learning home-schooling with adequate supervision can be comparable.

My understanding is that home-schooling with private tutors > the typical school environment > remote learning without supervision.

> You have to consciously start doing that and then eventually you'll do it that way as a preference.

For Japanese, it's opposite. People aren't good at English so Japanese tech writing/talk is everyone's preference. Also Katakana helps a lot to import foreign words. Top people learn English, import words, wrote their text, and talked in Japanese.

Now Japanese texts are getting not popular (due to not profitable) and many English texts are very easily accessible thanks to internet and it's lingua franca. So finally many Japanese are going to learn English to catch up.
Are there more important things to solve? Of course.

However, this particular topic on this particular message board is about dotfiles and the alternatives.

Dotfiles are a clumsy mechanism that came from the early days of Unix.

There are better alternatives that provide the same lack of "unknown/unnecessary" directories and files in the user's home directory/folder.

Each of Windows/MacOS/XDG-compliant OSs has the equivalent of:

1. A configuration directory
2. A storage directory that is maintained between user logins and/or application execution
3. A temporary/cache directory that is not guaranteed to be maintained between user logins or application execution.

The different languages/runtimes also have ways of retrieving these locations which are cross-platform but return the correct values and should be used by all applications that are written to modern standards.
The wall of contributions (with different degrees of green) is also pretty ill conceived, with a 1000 lines of code commit having the same value (one contribution) than opening an issue.
Also, the "bugs evolve away" would need evolutionary pressure being involved. But the explanation I got was the available biomass for bugs is such that any chunk of bugs killed on the road was easily filled by other bugs eating their lunch and procreating.
They're not doomed. If anything this will show the hyper fixation on academic schooling is misguided. Only the very few whom persue higher education may be required to take higher math that they will also not use.

Most academics is for the enrichment of the school and instructors, not because it's an effective education.
I think the thick black border marks the "default dialog button", not focus.
Those who were involved with the Mozilla open source project or the company in the years of ~2013-2014 will heavily disagree.

There was a strong and long debate about the pros and cons. One of the strongest argument against was this here, including interoperability. I believe Cory Doctorow has also written multiple articles against DRM. I agree that DRM is generally bad.

However, the arguments for implementing it were the following: at least two other browsers will adopt the tech and that will allow it (per W3C process) to graduate from a Candidate Recommendation to a full Recommendation, making it part of the web platform.

On top, what would it mean for marketshare if people had to install a second browser just for watching movies? Would the non technical users accept and understand this without switching to a browser that they’d consider "actually feature complete"?
> If a user doesn't know what .ssh/ or .bash_history are, and it can hurt them to accidentally delete or modify them, why show them by default?

Because they are there. To prevent accidental deletion you can show an icon with a skull and crossbones or name a directory "configuration files" so that it is obvious what's in there.

> if they do get them there is no safeguard to stop them destroying the system

If the folder are named or labeled as "operating system" then the user will probably understand that it is better not to mess with it.

> In what reality is someone developing software and building Docker containers who doesn't understand the concept of hidden files?

Hiding hidden files is annoying because you have to add -a to ls command, have to add an option in Bash to include then when matching against a star pattern and to configure Explorer so that it shows them. It would be easier without them.
>My understanding is that home-schooling with private tutors > the typical school environment > remote learning without supervision.

In pure academics, maybe. What about your children's social/well-being from not interacting with their peers?
You might not believe me, but the decline of the insect population (also on the frontpage) and the fall of test scores and the fall of sperm quality since the 90s have the same single origin.

And nothing is being done about it.
That's why IC layouts used to be called "floor plans". They were floor-sized drawings on which people laid out lines with tape. The floor plan was then photographed from above and color-separated into masks.

"Back into the 40s?" ICs aren't that old.

Printed circuit boards have long been laid out by hand, and sometimes still are, but they're not usually photo-reduced. They're laid out at full scale.
> there's an automated rule here that tries to punish discussion of this topic, since Internet censorship doesn't belong on Hacker News apparently.

There's no such automated rule, and internet censorship gets discussed on Hacker News extensively.
