Even if you have a bump allocator, the fact is that a linked list requires storage for the pointers, which are not needed in an array. That makes the list bigger, and bigger means worse from a caching point of view. Fewer parts of a linked list fit into a cache line and so on.

Plus the pointer traversals are dependent loads. Until we load node->next, we don't know what address that is, so we cannot pre-fetch node->next->anything.

But when we access array[i], it's possible to pre-fetch array[i+1].

I'm still using linked lists because of the flexibility, functional substructure sharing and allocations you can avoid, but let's not kid ourselves.

And exceedingly rare.
I have some unprofessional sociological suspicions, so I will lay them out as assertions with this caveat serving as the blanket qualifier.

First, some observations:

1. Research has found that the probability of conspiratorial thinking is quadratic with respect to political extremism in either direction.

2. Dangerous political movements are predicated on an "us v. them" mentality, almost by definition of dangerous. What makes a group dangerous is precisely the fact that they are willing to harm people in concrete ways, and willingness to harm requires a targeted "them".

3. Distributed censorship and other forms of persecution are actually conspiracies with an inherent "us" and "them." The more groups (media companies, government, etc) censor similar ideas in similar ways for similar reasons, the more apt appears the description "they conspired against those ideas."

Therefore: the problem with censorship is that it makes the conspiracy theorists right. Censorship is also an acknowledgement that the censor and censored are in fact different and opposing groups. No longer can the censor say "come on guys, we're all on the same team here," they have ceded that high ground.

Both of these effects can actually help extremist groups attract new people. As they say Plures efficimur, quitiens metimur a vobis: semen est sanguis Christianorum: the blood of the martyrs is the seed of the Church.

HOWEVER

All of this analysis is a kind of "perfect sphere on a friction-less plane" view of the market of ideas. We must not fall into the trap of thinking that if we removed all censorship, the market of ideas would be efficient. If censorship is an effort to artificially devalue some ideas, there is also the countervailing force of amplification which artificially inflates.

The problem is that money has always (and technology has recently) enabled people to distort the market of ideas through amplification. There are actually bad actors (e.g. Russia) who actively amplify ideas beneficial to their interests by putting engineered talking points into fake social media accounts.

I do not believe it is possible to fight such a strategy on the same terms. Amplifying contrary ideas simply increases polarization. Attempting to re-level the playing field via censorship has the problems I listed earlier.
It probably means changing laws to allow users to hold internet platforms liable for harms caused. All parties can then have their day(s) in court. That seems fair to me.

While I agree with other replies to your comment that the internet became prolific/mainstream much faster than the printing press, I think your point still stands when looking at things from the perspective of a human life or culture. We're still the same humans that we were back when things perhaps didn't change as rapidly.

Sure, the internet was a lot faster at becoming ubiquitous, but humans are still humans. Our society still needs time to adapt to internet, because 25 years old, as you point out, is really not that much on the scale of a human life or an institution or society.

> because we can't create the yesterday in the lab either.

We have access to memories of the past which are physical. Records in the rock strata of Earth's formation, neuronal connections in our brain of Grandma's barbecue and who was in attendance, red-shifted EM signals traveling since a few seconds after the big bang.

The information of these processes and events is never lost. "The present is the key to the past" and such. Even every causal relation since t=0 could be worked back to arbitrary accuracy from t=n for a near-omnipotent civilization. One still following all laws of physics, just very advanced and capable.

QM creates a novel situation imo where nothing, not even near-omnipotence, allows one to probe "pre-measurement". The very act of measuring causes something to occur. Scattering a photon or electron or proton with something is the smallest tool in quantum field theory, probably the most well studied near-fundamental theory in physics. There is no way in principle to ever probe pre-measurement because there is no disturbance-free way to observe. There is no sub-photon. There's nothing besides particles and fields to investigate with. There's no tool to build to improve things. The type of knowing in knowing the superposition of states pre-measumrent is not the same as knowing the past. We can arbitrarily improve tech to investigate the past to arbitrary degrees. The information of the past is out there, physically accessible to some kind of observer. In QM, there is no way to improve that lack of knowledge. It is forever inaccessible to any type of observer.

If this still all exists for you, then what about the past? Why doesn't that exist? What notion of "exists" could you thread that denies the past's existence yet asserts the existence other inaccessibles?

Surely there are kinds of existence in each of these ideas.

(To be clear absolute size isn't the only motivator for QM, just one aspect of it).
> Someone's preference

It's not a personal choice (preference) when it cause another being to suffer (caged, artificially inseminated (raped), babies taken away, fed horrible food, etc.)

Unfortunately, i don't think anyone is that dim to conclude that the accusations against the Chinese government is out of pure empathy for the Chinese people.

If it was the case that your empathy stretches across the pacific ocean for the Uighurs, then why does it not stretch for the Palestinians? I think the actions taken by Israel is way worse of a human rights violation than China is doing, but because the West supports Israel, it turns a blind eye against the Palestinians?

Moreover, one can formulate and theoretically, yes accusations should not equivocate as hatred for the Chinese.

But in practice, this isn't true at all.

> so that the service quality degrades and the private sector can swoop in as the saviour. This is controversial because:

There are a couple of other reasons:

The Lansley reforms were about increasing non-NHS provision. They mostly failed because private providers simply can't do the job for the money the NHS gets paid.

Where we see private provision (for example, specialist commissioning in mental health services, or learning disability and autism services) we see terrible standards of care. Winterborne View, Whorlton Hall, St Andrews, are all non-NHS providers. Cygnet Health have had a bunch of inadequate CQC reports.
The irony of the paradox of intolerance is that Popper defines it in the context of physically violent and irrational intolerance:

"But we should claim the right to suppress them if necessary even by force; for it may easily turn out that they are not prepared to meet us on the level of rational argument, but begin by denouncing all argument; they may forbid their followers to listen to rational argument, because it is deceptive, and teach them to answer arguments by the use of their fists or pistols."

Most citations of Popper's paradox are used, however, to justify suppression of "dangerous" ideas with very indirect and nebulous notions of harm on the level of social contagion. So the irony is that modern uses of the paradox is intolerance beyond acceptable limits for Popper.Or, in other words, in a society with a developed norm for tolerance, the intolerant can only resort to the paradox to censor ideas as long as people just believe the paradox naively and don't take a careful look at the potential harm caused.
Popper's book is more philosophical than historical, and I'm as annoyed with people who only know one soundbite from it as the next guy, but over time I've come to believe that the paradox encodes an important truth: there's no reason for me to support freedom of speech for those who don't support mine. Maybe the way of the future is something like Substack, groups of people who say "we'll protect each other's right to speak freely, but if you want to enjoy our protection too, you must contribute materially". Without such coordination, there's no point playing the good soldier in favor of free speech for everyone. Freedom for those who care enough to coordinate is the only way freedom ever worked.

I think there has been some research on longterm digital storage. I think there was one that encoded info onto glass, which supposedly doesn't have the same longterm (centuries) storage concerns.

You could probably warehouse the data in something like the world's seed banks - bunkers distributed around the world to preserve the genetic material. Technically you could even store the data similarly since there has also been research on DNA data storage.

With Tailwind: defer decisions about assigning classes until you've built enough to see what the proper abstractions are, then just refactor out the repeated utility classes. There's even plugins that will consistently sort your Tailwind classes so that refactoring can be automated by simple search and replace.

> There's also benefits to middle-operations, such as text editing (although text files are so small that inefficient operations aren't a big deal anymore).

Applications operating on text would normally use a rope (aka cord) or gap buffer. A linked list would have horrible performance because random access within the text is important for most applications.

> (I'm building up GBs of data: so saving redundant chunks like this really wins)

You’re likely spending a huge amount of memory to store pointers between elements within the unshared chunks (8 or 16 extra bytes per element adds up in a hurry) so it may be worth investigating some “chunking” so that you only have to use pointers to link between chunks, which can be stored continuously.

Alternatively, consider whether the index representation used by suffix arrays will work for your use-case: https://en.wikipedia.org/wiki/Suffix_array
>They won't be able to look at your data,

They totally could. All they have to do is trick you into sending a properly encrypted message to an endpoint under their control. Then they can decrypt the message, read it, properly reencrypt it for the entity you think you originally sent it to and then send it along.

Because they control the entire infrastructure and user experience this sort of thing would be trivial for them to do. An unsigned, anonymous PGP message (the equivalent) would actually be better.
MSVC STL uses the golden ratio instead of doubling for std::vector allocation which means that you can reuse contiguous runs of previously deallocated chunks to fulfill future allocations, while still meeting the standard asymptotic O(1) bound on push_back.

I believe that GCC's libstdc++ tested the strategy on a set of real programs and didn't measure any actual difference so they still use doubling.
