> RAAC has been shown to have limited structural reinforcement bar (rebar) integrity in 40 to 50 year-old RAAC roof panels, which began to be observed in the 1990s.[22][23][24][25][26] The material is liable to fail without visible deterioration or warning.[22][26] The material is not the root cause, rather inadequate roof maintenance, which permits water infiltration, and decisions by building owners as to repair or the replacement of existing roofs, which is a part of cost-benefit analysis.[27]

> Professional engineering concern was publicly raised in the United Kingdom in 1995 about the structural performance of RAAC following inspections of cracked units in British school roofs,[28] with it being observed that it was likely that RAAC in other countries may exhibit problems similar to those found in the United Kingdom.[18]

No, that's more like potlatch. "Book communism" would be if authors owned the printing presses. (Or maybe if printing press technicians owned the printing presses.)
Tracks are now so narrow that thermal expansion might throw the alignment out of whack.
> There is no greater folly of contemporary human society than the purposeful restriction of such vast and easily shareable repositories of knowledge

This is objectively false. There zero actual harm being done here. There is very little, if any, evidence that the vast majority of the 500k removed books contain information that actually provides value to people, as opposed to being fiction and political advocacy non-fiction (for instance, the vast majority of the list of 1300 "banned and challenged books" (that contains many duplicates and is shorter than IA claims)[1] that the IA is clutching their pearls over are almost exclusively non-informational) that result in zero harm when taken away from people.

You also pointedly ignored the fact that the greatest repository of knowledge in human history, by orders of magnitude, is the Internet - even if you restrict yourself to the parts that people have voluntarily made free, you still have the ability to learn everything you need to live a comfortable life, and learn more than you have time for in a thousand lifetimes.

Demanding that the entertainment works that authors wrote with the express intention of making money (and who did not consent to their work being put on IA) be made freely available, regardless of the massive amount of information already voluntarily made free on the Internet that serves almost every need you have (learning to sew, fixing a leak, doing your taxes, getting the equivalent of a PhD in math), is the absolute peak of entitlement.

The only vaguely reasonable vector adjacent to your argument is that academic publishers make their papers freely available, because that's actual human knowledge (and because the funding for the research doesn't come from the publishers).

> We prevent this achievement due to our attachment to a specific economic system that serves as the current means of financially supporting authors.

Now you're just advocating communism, which is one of the actual greatest human follies of all time, and has resulted in tens of millions of deaths and the suffering of hundreds of millions more.

This comment is utterly inappropriate for HN. It is naked political advocacy that is emotionally manipulative, factually incorrect, and contains zero content that aligns with HN's goals of "stimulating intellectual curiosity".

There is no perfect choice here.

I left the MS Windows ecosystem in around 2001, did not really use XP or 7. I was on various linux distros until 2015- and for my needs at the time they were great! I used mostly desktops (power management/sleep not a big issue) and did not have to interop with "regular" users using MS Office, etc. I did some development, and in this area Linux excelled. I also had time to tweak and twiddle until things worked well.

2015 - 2021 I was on Mac OS. It was an improvement over Linux in several ways- mobile HW was great, sleep no problem, and I could interoperate. MacOS is great in so many ways (and as mentioned Apple HW is generally top-notch), but not perfect. For example, they don't really want you running "unapproved" (unsigned) software, and I understand network is needed to check if the software is approved: https://appleinsider.com/inside/macos/tips/how-to-launch-any... . Together with the fact that I had very little HW control (can't upgrade or replace parts myself on Macbooks especially) and that Apple make their stuff software pretty "sticky" (hard to get your data out) I ended my run using MacOS as my primary computer.

So now I am on MS Windows again, like the old days. It has the issues indicated in the article for sure- but I do feel a little more control than MacOS, strangely. Its easy, it mostly works and gets out of the way, and I can still upgrade RAM etc (for now, anyway- ARM PCs might be more like current MacBooks and could change this). Dev is better than in the past, and interop is no problem. The main reason I am on Windows is backward comparability. As I have aged, I value being able to use old things- and on this MS Windows is unmatched in my experience. I will see how long I last before the next leap ;-)

Any evidence that the majority of the books were fiction and political non-fiction that present near-zero value to "humanity"?

I live 15 minutes from downtown Phoenix, and it took them 2 years to expand to my location. Over 4 years after Waymo launched beta testing here..

Waymo cannot take me on the freeway (backstreets only)

Waymo cannot go to the entire city of Peoria, Surprise, Goodyear..

Waymo cannot go to the entire western half of the state.

If you live 30 minutes from the downtown city centre, there is a 30% chance Waymo can go there. Waymo serves higher-end areas only today (Scottsdale, Tempe, Chandler) - if you live in a poorer area, no Waymo for you.

I have family who lives in Scottsdale and Surprise, Waymo can't take me there.

My dentist is less than a mile from my house, Waymo can't take me there - but can take me to a fashion mall in chandler.

Is it better than Uber/Lyft? Experience wise, sure, but their snail's pace expansion is disheartening. Not to mention the freeway issue.
you are right and thanks for adding on my ELI5. TBH I never used nixOS, only guix, which does not use a central key to sign packages, and uses signed commits (https://guix.gnu.org/manual/en/html_node/Commit-Access.html) , the project is sponsored by the FSF and it's the official distro for the GNU project, so they take security very seriously. (You can always install a random channel and throw all that out of the window if you want).

(quick edit) Guix packages are basically .scm (scheme) files on git, so the fedora/nix example does not apply either. Every file can be opened and inspected, most of them are basically a git clone + checking a hash. You can decide to use substitutes (binaries) or no, and substitutes are usually similar byte by byte across systems. As an example, this is the guix config for installing CRIU: https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages...

Given said that, I am ready to spend some of my funemployment time installing and using nix as my daily driver for a few months, so I will have more info and first hand knowledge of all that.

> The basic issue is that if a library is filled with electronic books, the publishers will stand to lose a lot of profit.

Profit they're only getting because they figured out a way to cheat the concept of ownership and get around the first sale doctrine.

> The physical restrictions in a library - ala, only 1 person could read it at a time - is what prevents publishers from trying to charge more or prevent it.

Publishers hate digital lending that doesn't give them money, even when it acts just like a physical book: one person at a time, takes hours to be restocked, etc. Restrictions like that don't stop publishers from fighting back; only precedent keeps them in check.

„to an unspecified time in July“ is not really „indefinitely“ Ars Technica.
I recently found a bug whose fix amounted to one-liner. It all started with random CI failure when I was working on adding some new functionality.

I've rerun test locally -- no fail. I've changed the seed to one that was used in failing run -- nothing.

I add a loop to the code to repeat text hundred times -- still nothing. I run the test in bash loop hundred time -- 3 fails. So this already hints on some internal problems. I fixed every possible source of randomness and verified that all the inputs are identical between the runs -- still fails only once in a while. I started building MWE, but the function involved in reproduction is fairly complicated. I'm left with a hundreds lines of Jax code which fails in couple of percent of cases.

I look at the output of the compiler, and it is identical between failing and successful runs. So the problem is in the compiled code. The compiled code is ~1000 lines of HLO (not much better than assembly). Unfortunately HLO tooling is both unfamiliar to me and not well fit to this case (or at least I couldn't figure it out). So I start manually bisecting the code. I'm finally left with ~30 lines of HLO. It fails even less often (1% maybe), but at least it runs fast. It also seems to fail in exactly the same way (i.e., there is single incorrect output that I've between 3 fails). Now that's something maintainers can be hoped to look at.

It turned out that matrices with same content but different layout were deduplicated, leading to, in my case, transposed matrix being replaced by non-transposed one. The hash used for storage did take layout into account so the bug appeared only if two entries ended up in the same bucket (~3% of times). The fix was an obvious one liner [1].

The US subsidizing the book market would be an incredible waste of my taxes, given that the majority of published works are fiction, political drivel, and non-fiction memoirs that provide near-zero value to "humanity" that the root poster is clutching pearls about.

The IA's collection of books they had to remove almost certainly has the same composition, and therefore the same loss in value (roughly zero) after being made inaccessible.
Here’s a representative example of what I mean, an issue from one “modern” Linux desktop:

https://gitlab.gnome.org/GNOME/gtk/-/issues/3787

At least with Windows you don’t have to gaslight yourself into thinking that blurry fonts are better. If you have a setup with multiple high-res monitors (or, God forbid, have to mess with scaling), it takes a lot of work to be happy with the looks and feel of a Linux desktop compared to what you get out of the box with Windows or a Mac.
You’re the ideal windows user…whatever that may be??
Yes, this is the correct solution - reduce copyright term.

I don't know if I agree that 14 years is right, but I'm sure that pretty much everyone can agree that 1 year is too short, and 60 years is too long.

> Microsoft to get serious against these consumer-centric companies like Apple and Google

Microsoft can't do that. It's not in their DNA. Every time Microsoft has tried to make something consumer-centric it ended up flopping eventually. Sometimes things lasted a surprisingly long time!

But their consumer-focused stuff like Zune, Xbox, even their keyboards & mice, eventually all kinda lost focus.

Windows mobile was a weird one because they tried to use the same formula they always use - a corporate OS that had all sorts of knobs and buttons for SysAdmins to manage corporate phones. You could join a Windows phone to a domain and manage it.

Xbox was pretty successful for a while because MS just has so much clout with game developers.

Zune flopped HARD. I think the Surface product line has been kinda here and there - a total failure for consumers but some businesses like it... but not many, because most businesses have a relationship with Dell.
I also have both, but only because I can get HDDs for $10 to $20 per TB while SSDs still cost $50 to $100 per TB.

“The centre must be a place for everyone – not cater to 12 specialists and ignore 12,000 others. It must initially give a sense of self-possession, It must arouse curiosity. It must lead to understanding , not just knowledge. It must be a place of wonder. It must give immeasurable qualities of comfort and joy and discovery with others. It must inspire the visitor with ideas through active participation. It must be an emotional experience, with intellectual satisfaction and it must be fun”.

Taking copyright away on death is a bad method, and that's a reasonable argument against it.

It should be a fixed term that isn't very long. And if that term ends before death and they want more money then great, write something new.

I think most people objecting to copyright lasting after death are really reacting to how long it all is, and the average amount of time that is. Some of them really don't want it to go past death, but I think most of those objectors would be fine with copyright that lasts exactly 25 years no matter what.
this sounds like an LLM for sure.
Translate buttons work well.

Even if there is no physical reality, and only one consciousness (your own), space and time must exist a priori, as Kant said. There could be no continuity of experience without time; and without space, the universe observed by that consciousness would have no structure at all - it wouldn't consist of anything other than the observer itself. The mere fact that you can conceive of different ideas implies that there must be a separation (i.e. space) between them: if "all is one" - as the strawman hippie would argue - was actually true, you couldn't disagree with that statement, or even imagine the possibility of it being otherwise. So because you can, it is certainly false.

Although space and time are not the same, there is an obvious connection between them: as things are farther apart in space (whether physical or conceptual), it takes more time for them to affect each other. For the terms "cause" and "effect" to have meaning, the time between them cannot be zero. And at least special relativity has been shown in cellular automata, where both time and space are discrete, so it could be the same in our universe?

Wolfram may be a crackpot, and the Ruliad just another multiverse theory that could never be verified or disproven. But I think there is some value in it, straddling the borderline between philosophy and physics.
Personally I don’t hold this view of China. I think they invested in manufacturing while we divested and now they’re simply reaping the rewards of those investments by producing superior or soon to be superior technology.

A lot of people in the west have a vested interest in discrediting Chinese manufacturing but if we put our heads in the sand and refuse to see what is really happening they’re just going to pass us by.

Note that basically every automobile producing country puts government money in to that industry so highlighting that China is doing it is on its own meaningless.
