>where you need hard O(1) insert even with a high constant factor

You will need a truly concurrent memory allocator for that, too... or if you are just the kernel (one of the reasons the linux kernel can benefit from linked lists)

Overall, allocating new objects/memory is not guaranteed O(1).
> Seems like “web3” has completely missed the mark and is actually highly centralized, arguably more so than web2.

In the sense that the “web3” brand is mostly used to make proof-of-concept and crypto startups in the Ethereum ecosystem, which is just one ecosystem, and a highly centralised one at that, 100%.

Creating a decentralised web is extremely difficult. Most Ethereum web3 projects are more like concept art within a research project.
Really admire your work man.

I honestly felt nothing but contempt for the oligarchic structure of fact checking. Facebook hired organisations like the Washington Post to do their fact checking. I have not forgotten how many people there lies killed in Iraq. I don't forget how the journalists at the time were willing to compromise their ethics in exchange for White House access and exclusive stories from the front lines, simply because journalistic interest is not the public interest. We also saw more recently during the pandemic incompetent journalists without adequate medical training censoring BMJ articles from Facebook: https://www.bmj.com/content/376/bmj.o95.

You are making one of the only tools I can see that can possibly make "fact-checking" a reality in a nominally unbias way that can be broadly accepted by the public. A democratic fact-checking system for a largely democratic website. Even if birdwatch will get things wrong, I appreciate the effort to reform this institution of "fact-checking" with something righteous and moral. No need to touch on my spicy political views, but I think this is a transparent, scalable, fair tool that can truly be embraced by the entire society rather than simply leading to a partisan divide.

Your system understands I'm on social media because I want to hear what the average person has to say, and I would go to a news website if I wanted to get a news websites take on what the facts were. To me, if a news website wants people on twitter or Facebook to pay attention to their "fact check" editorial, they should do it the same way everybody else has to. By creating compelling writing that gets attention and that people agree with.

It must be extremely hard to enter the GPU market.

Hopefully Intel is aware it will take them some generations of work to become competitive. Hopefully they will stay in the game.

AMD is starting to get its act together and the next generation of GPUs will place some real competitive pressure on Nvidia.

Nvidia shows all the hallmarks of a market leader that has had no effective competition, resulting in overpriced offering with limited features that make things hard for its users. Consider for example that Nvidia artifically limits functionality so that consumers cannot access the full capabilities of their GPUs - with good competition this sort of thing will come to an end.

I find RSS has the same problem as to do lists for me. It all gets too much and I dump it. Another inbox to manage where it's a roll of the dice if I get any value or find anything interesting.

Thanks for the question. I bring this up because getting a diagnosis if you grew up in a community where mental health is stigmatized can be really hard. But getting help in case you can't get that diagnosis in a lower key way (e.g. ADHD coaching) doesn't have to be out of reach! This is 1 of the many reasons we don't require a diagnosis.

In terms of pricing, we offer financial aid to those who are in need as well. Hopefully we'll help bridge this gap and are actively working with a few non-profits to help sponsor these costs too!

> In this scenario, since your input energy is basically free, more storage capacity = more money, and switching to clay could triple your effective capacity.

That's all fine and dandy, but the whole point is that projects are evaluated in terms of money and not joules. This means that if a material like clay is , as you claim, 3 times more efficient but ends up costing twice or more to replace and more to maintain, you are in reality looking at a prospective best-case scenario that lies somewhere significant losses or irrelevant gains.

Meanwhile, building the exact same sand-based prototype right next to the original one would literally double the capacity at a far smaller cost.

People want to get warm, not discuss whether clay or sand pack as much heat. Half the world could not care less about what goes into AA batteries.

Projects are evaluated in financial and economical terms. It matters nothing if there's a theoretical possibility that some other material or design is more efficient, if it's savings are irrelevant. The world rides Volkswagens, not Formula 1 cars.
There's mountains of evidence. They haven't been theories for a long time.

It’s hard enough finding a way of doing something. Apple doesn’t document anything. Instead they point you at WWDC videos which they take down after 5 years (or even less) that hold critical information needed to develop for their platform. If they want people to do things “the right way”, then they should document it properly instead of just pulling things arbitrarily or putting all their documentation in the form of videos.
I’m betting they collateralize the debt, selling all or a portion it off to reduce exposure.
Would love to hear people weigh in on pros and cons.

> [...] as a context free grammar using EBNF notation. This is impressive, but maybe a little more complicated than I want to get with a basic security tool.

I apologize if I'm being trite, but Context Free Grammar doesn't mean that the semantics of whatever that grammar describes is simple. It just means that it's simple to parse into ... something. Parsing a CFG is also not impressive in the slightest. It is, in fact, trivial since the 1970s. Anyway,

You shouldn't be scared of the CFG bit... you should be scared of the semantics.
IF you can execute code this way (which is an IF) then it's way more severe than a 2.9, and you could absolutely do anything you want with the system (you'll be root).

Complexity High isn't about what an attacker gets, it's about whether or not any specific configuration must exist for the attack to happen. For instance, if an app that talks to several services over different file transfer protocols has a vulnerability in only the FTP component, and these are not under attacker control, that's Complexity High.
ya I think that is true. I doubt people planning this write it that bluntly. I don't know what men who plan this say and write, probably something vaguely sexual and provocative.

I do see women write "not looking for anything serious" somewhat commonly.

OTOH I think it goes nowhere if you write you want a serious stable relationship, maybe wife and children at some point. I am guessing but I think it scares some women off and it doesn't really build attraction with them. I have seen women write this in their profiles and when you mention you want something similar the conversation fizzles out real quick. I don't think there is any hard rule here though. A lot of factors can affect this.

Nobody claimed this was happening. Just because the NYT says "we're only doing investigative pieces on tech," doesn't mean that they start fabricating lies. It just means they don't do fluff pieces.

I think that is a faulty assumption, and maybe that is what you got some down votes.

A loss doesn't always mean reinvestment. Reinvestment doesn't always translate to growth. Growth doesn't always Translate to profitability or market value.

It is staggeringly common that businesses fail despite investment and despite growth. Sometimes the product is bad or simply has limited scalability.

Valuations can change rapidly based on expectations of future profit and market conditions. This is especially true in Tech and new companies where valuation is based on future potential and not current profitability.

The general idea is that even if you do a lot of reinvesting and grow your market cap significantly, that market cap can evaporate if it seems unlikely that a company will actually turn into the cash machine people hoped that it would.
Having linked nodes of a hashmap, is just that - I'd not call it a linked list.

Seriously, though, they are probably compensating for failure to get the "can" launching system (aka "starship") online that would enable lofting new higher bandwidth satellites. The cans would have more and, more importantly, bigger payload. If it takes too long to get the can going, they could probably shift to Falcon Heavy and a bigger shroud. But without the can, it costs too much to operate, steady-state.

Starlink is pretty severely limited on aggregate bandwidth. They could do a lot to mitigate this by coming up with ways to deliver the hottest realtime streams (e.g. World Cup) via a broadcast protocol, and to partner with Akamai etc. to cache a few hundred TB of other content aloft, to save on uplink bandwidth.

Capping is easier.

This kind of data structure often has a buffer + associated metadata. If the metadata+pointer fits into 1-2 cache lines, storing it in a vector can give be win vs. storing the next/prev pointers next to data + metadata.

> the best example is the UX of the main sites like car tax

To give you a comparison, in the US you need to go down to the DMV with a wad of forms, get the bits you can't fill in filled in, let someone make up a price, decide you haven't filled a bit in properly, send you away to a different window, get something else filled in, pay a fee for the filling in, hand the papers in at yet another window, pay for the actual registration, get a temporary registration slip, pay for a set of plates to actually be fixed onto the vehicle, pay for the stickers that say you've paid for a plate, all of which paid by cheque at various windows, with no real idea of the total cost up front.

In the UK (where cars tend to keep the registration number they're given on first registration), you go to the DVLA website, follow the prompts for the kind of paperwork you have (reminder letter, V5 registration certificate, V5C "green slip" if you've just bought it that the previous owner tears off the bottom of the V5 and gives you), it tells you how much it'll be per month or per year, you put your credit card details in, and that's it. Paid, done, nothing more to do.

> Requiring pointers is implicit to the definition of linked lists, and calling it out here is silly.

The usual complaints are that "Safe Rust doesn't let you do this", when unsafe Rust is right there to let you operate on any soup of pointers datastructure that you'd want to implement.

> you don't really need either ref counting (again, pretty obviously, witness every real world implementation)

If you implement DDL in a memory managed language, you effectively have the same behavior as you would in Rust with Arc or Rc. The ownership of the nodes then belongs to the GC or the RC value. You don't have to think about it because you're abstracted from the lifetime of each node by the language and runtime.

> or hierarchical ownership outside Rust

The ownership/borrow checker requires hierarchical to operate, but it doesn't stop you from writing unsafe Rust.

> Conceptually, the list as a vague concept owns all the nodes. The ownership just stops being expressible directly through references the way Rust wants it to be. But you don't have to re-invent hierarchical ownership to implement DLLs in other languages, because it's not really there in the problem. You just have to accept that they're always going to suck under Rust's ownership model.

Yeah, and that's what unsafe is for. Most code doesn't need vague ownership, though. I'd go as far as saying that the nudge towards clear ownership helps both maintainability and performance.

My concern is with the prevalence of this idea that unsafe Rust is not "real Rust" or that the existence and use of unsafe Rust somehow precludes any benefits of Rust.
Didn't you just define a superior use case for each of the three utensils? Why does the fork lose? I can't really think of any meal where a knife on its own is useful. If I could only pick one to eat all my meals with, I think the fork would be most useful.
So, if this becomes a permission, it would be another annoyance like the cookie banners. Akamai is requesting client information, allow or deny? Who would know what that even means, outside of tech?

The gist is, privacy and security has to be in the defaults to be useful. The amount of stuff that can afford to have a human in the loop is in practice minor, and only be reserved for important things that people can actually understand.
I would argue that a fork can scoop certain foods more effectively than a spoon though. Especially when eating off of a plate rather than a bowl. Fork interfaces with the flat surface better.
I've often thought the same thing and have heard it from others too.

Body doubling seems to be a common technique. I've often considered if some form of self surveillance (webcam, heart rate, computer usage metrics) combined with ML could observe and "nudge" you along.

For (intrusive) thoughts sometimes I'd rather not fight it because I'll randomly suddenly remember something that I couldn't recall over an hour ago, or be reminded, or see a vague connection to another topic that could be useful to investigate later.

Maybe it's not so much being reminded to stay on task but make it as frictionless as possible to capture something and put it away safely so before you get completely derailed...

As for attention "drift" when you're forcing yourself to work on something that really saps your energy so your subconscious is trying to protect you by pulling you away? The only thing I've found to help is to organise my life so that the conditions that cause that to occur have less of a chance of happening (getting enough sleep, eating protein, taking medication at consistent time with food, meditating, listening to my body and taking regular breaks to prevent crossing the overwhelm threshold, do enough housework on routine so there's no reasonable excuse to do a load of laundry) which I guess is what a lot of coaching will try and help you do, setting up practical systems to remove triggers and optimise the ideal conditions (my speculation).

I can't remember why I started writing this reply or if I'm even anywhere close to it being on topic now, but rather than delete it, I'm just going to leave it here.
How is their gpgpu performance?
Relevant to the top-down nature of NYT coverage: https://twitter.com/DaCaveOfWonders/status/13661682776769208...
It would rebalance on insert with O(log N) performance but chunky constant factor, keeping the ordering so access by index is also O(log N) with low constant factor...

Which is why usually you would use a red-black tree rather than a BTree, as it has much lower constant for insertion and access by index. However higher for traversal in order.
It's difficult to get a man to understand something when his salary, or his hacker news handle, depends on not understanding it.
Regarding Twitter’s reduction in force, there is no choice
I may be mistaken but the Fediverse are a collection of projects using ActivityPub or similar protocols. Usually they are federated not completely decentralized (or blockchain based) like "Web3".
Twitter bans people for not following a very narrow set of gender and racial hierarchy rules. There’s no nuance here.
how do linked lists fit the regularity requirement? the only regularity in this pattern of access is the offset at which the next address to fetch is stored. this seems like a nontrivial amount of logic and state for the prefetcher to keep track of, unlike something like base * scale + offset when e.g. traversing a 2d array.
Yeah, chopsticks are like using your fingers without getting them dirty. I've started using surplus takeout chopsticks for cooking. (I have nice chopsticks, but they give me them anyway). I have a jar of chopsticks[] on the counter and wash / reuse. They whisk eggs, pick up bacon, stir pasta, snag a bit of shell from the egg you just cracked into the pan, etc.

[]: chopsticks, fish turner, measuring spoons
Usually you want a smaller growth factor than that to allow for more reuse. (Also: what’s VPP?)
> The market is not going to decide Apple’s patents are worthless, California Real Estate is worthless, their factories and manufacturing equipment is worthless until there’s some world-ending cataclysm.

I'm not sure why you think there has to be a world-ending cataclysm for this to happen? If there were any major change in the way societies or economies were organized, Apple the entity could cease to exist entirely, or some/all of its assets could cease to belong to them. Like for patents, it certainly seems like the world is very far from deciding to abolish IP, but if society wills it, it is very simple to do.
Couldn't all those things be said of centralized services?

I always have the same concerns as you're pointing out, so I don't mean this critically, but reading your comments made me realize most of them could apply equally to either type of system.
>Yes, they can, and I'd rather avoid argument from authority altogether.

Proof by authority is the worst. Yet, linux kernel can have valid reasons for, but they are intrusive lists with the data having a pointer to the next.
