Doubling the vector size each time it needs to be enlarged takes care of fragmentation/memory overhead, in practice. Or preallocating if you know the rough size.

It does take some discipline to avoid the storage of pointers, but once you get used to that it’s quite fine.

You can use decentralized alternative domain name systems. OpenNIC is completely decentralized and there are a few projects which implement DNS on a blockchain, that would be the best solution to this kind of a problem.

The explicit 1 TB/month data cap is fairly generous for a satellite-based service. Speeds are more important/concerning.

I'd also claim that anyone who didn't see explicit data caps/throttling coming for a satellite-based ISP service needs a reality check. Ever since Starlink launched I saw a lot of arguments being thrown around about how SpaceX would just launch more satellites using 'their fantastically affortable' Falcon 9 launches as the customer base grew so that it wouldn't be a problem (e.g. in HN threads and particularly in r/spacex and r/starlink).
Pre-merge, nothing. Now you could probably take that judgement to a majority of staking validators and force their compliance.

For more decentralized blockchain the court has no way to force shutdown of a smart contract.

That’s the whole value proposition.
"Which teams have been laid off at Twitter?"

"The human rights team has been laid off, according to a now former employee, Shannon Raj Singh,

The ML (machine learning) Ethics, Transparency and Accountability team is gone, according to a tweet of a laid-off manager.

The “internet technology team”, which helps keep the site running, has been cut to “a skeleton crew”, two sources told the Times.

An accessibly experience engineering team has been cut, according to a laid-off engineering manager.

The curation team, responsible for the Moments feature on Twitter, has also been cut, former employees reported.

Twitter’s communications department is almost entirely gone, according to the Verge.

This reminded me that OKC used to blog about results and data a lot. Before they got bought by Match it really did seem like they had some interest in matching people.

Cool that the new free speech-haven twitter doesn't allow advertising extensions internally or cartoons.

Some proponents of free speech really only care if their speech is curtailed and care little about anyone else's.
I'd only call it a scam when they advertise unlimited and still have caps. Otherwise you are just getting what you agreed and paid for. If you want to pay for a dedicated gigabit line not shared with anyone else, you can, it costs a lot.
This is super cool! So there are multiple patterns at different sizes because they need to be read at different heights right?

But thats the problem they are looking to solve… there are quite a couple of cold months in Finland and I think a large portion of their heating is electric/distict anyway so they might as well store heat rather than energy. This probably serves as a rather good balancing mechanism to the grid actually, and I could definitely see this be a thing I northern Sweden for instance , where electricity is basically free during the night and when it is windy it’s actually kind of a problem to get rid of it all.
> What to do?

Make housing less attractive as an investment vehicle. In my opinion the best way to do this is with the tax system (which, in NZ, currently favours property investment to a large extent).

Two proposals that are often discussed are a capital gains tax (CGT) and a land value tax (LVT). Personally I would prefer a LVT. A CGT would be an improvement on the current situation, but it would be a big impediment to freely moving to take up a new job or for family reasons. An LVT has the opposite problem of being a potential impediment to staying put if the value of your land increases relative to other areas. For an older person who is no longer working this could force them to find a new home but could be dealt with by deferring payments until sale or settlement of an estate.

I don’t think autonomous driving is unsolvable. But every single company in that field has shamelessly lied about the time tables for the availability of the tech. And there’s been zero accountability for it. Remember how 2020 was supposed to be the year we get fully autonomous vehicles?

The only thing unfortunate about the coverage is that the media was entirely complicit and exercised no skepticism or pushback against these seemingly impossible time tables for deliveries of such a clearly complicated and as yet unsolved problem. They just blindly regurgitated the tech industry marketing pr around it. Has any single car company ever demonstrated a car that can drive while it’s pouring rain out?

The ideal state of the world is that there are 8 billion people, we identify the one that is best at growing rice and put them in charge of growing all the rice in the world.

As opposed to what? Publishing tech companies' press releases verbatim? Advertisements for apps?

Journalism exists to speak truth to power - you say "anti-tech" but the reality is that tech companies have been trying to convince us for years that what they're doing is some exercise in advancing humanity, "disrupting" industries (read: breaking laws) and "connecting the world" (read: undermining democracy, manipulating psychological triggers for addiction). It's a good thing that journalists have at least managed to remain critical - I would prefer to shine a light on billionaire VCs and the companies they're funding rather than doting coverage.

"Those solutions" start off being hierarchical ownership or reference counting, but turn into "pointers or reference counting". Requiring pointers is implicit to the definition of linked lists, and calling it out here is silly. And you don't really need either ref counting (again, pretty obviously, witness every real world implementation) or hierarchical ownership outside 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.

I think my confusion about the use of "use" [1] is actually about what josephcsible is saying. It may be that copyright empowers you can write a license that limits how someone can use the material, but then it falls outside what is an "open" license.

> Either money is thrown at the efficiency of these heating capacitors, which brings at most small gains,

It really depends on whether the air in the system is a closed loop or not while they are building up the heat in the device. Sand is, at best, going to be about 1/3 as efficient as clay in an open system (hot air goes in, travels through some pipes, then comes back out as waste exhaust). This number is based on experiments with rocket mass heaters I've seen. It could actually be worse- I honestly can't remember if the 1/3 number was for sand, or the large rock (think bowling ball sized) + gravel mix, which was more efficient than sand.

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

If, on the other hand, air is blown in a closed loop, you really only risk burning out your fan and resistive heating elements faster (they don't get cooled down by fresh air). In this scenario, 100% of the energy eventually transfers into the sand, so you're really only losing money if you need to spend more on land for setting up additional units.
I think the issue here is that if you're the type that prefers the latter method then there's no real app for that and I'm not convinced you can have such an experience on an app. Best I can think of is that you provide chat rooms and pressure people into talking one on one. But the in person experience you're describing also highly depends on a lot of non-verbal cues, albeit noisy and easy to misinterpret. These cues don't translate really well in text (and I'm sure that the metaverse isn't going to fix this either).
Taste and skill are totally independent.

This is not true for things that matter. It's no coincidence that the example he chooses is movies, of all things.

Skill is the independent variable. When your skill increases, your taste will increase.

It's not more complicated than that.

But a lot of people make it more complicated than that because they have an incentive to.

Because convincing others that you have "taste" is a very useful skill (ha) in our world. It's how you can position yourself as a leader, manager, critic, etc. without taking the time to develop skill yourself. It's a shortcut.

The trick is having to decoupling the two, which this article tries at.

I'd take 1 engineer with skill over 100 with "taste" (whatever that means) any day.

Taste is a thing, but having taste without skill is a myth.
Fundamentally, it's being able to control digital assets, like a unique name, or digital currency, with your own device.

You can even forego the speculative aspect of it entirely, and just hold USDC/DAI. Sending value is as simple as effecting a transaction from your browser-based MetaMask wallet. It removes all dependencies on third party custodians and payment networks like Venmo or PayPal.

The technology still has major missing pieces, like privacy (which isn't helped by OFAC's recent designation that prohibits Americans from using the largest Ethereum-based privacy protocol), but the fundamental functionality is a major innovation and leap.

The majority of users don't comment anyways.
My initial thought is… why bother? There are so many vectors for energy loss from source to destination. If the sand is heated by coils, why not install on-demand heating on-site?
So I glanced at it, expecting something much much worse, but I was surprised to see it wasn't that bad. Even if you look at the final code for the final implementation, it doesn't seem much more complex than what you'd have to write in C. And a good chunk of the code is implementing traits from the stdlib, stuff that isn't strictly necessary, but makes it easier to make the API of the deque idiomatic and work well with other stdlib (and non-stdlib) APIs.

And regardless, this book is teaching from the perspective of intentional super-hard-mode. Most Rust developers will never have to write that much unsafe code.

Because it's not sourced from "authority". Because the authorities are just as polarized as the userbase, but have power they didn't earn, and are rarely held accountable. Or at least they used to be on twitter.

Twitter's staff leanings (at least previously) aren't a secret: https://files.catbox.moe/3mvjhv.jpg With the userbase being the "fact checkers" there's at least a chance of balance, if not unbiased research. With their pre-Musk staff there was approximately a 1.3% chance of balance if political donations are any measure.

We'll see once changes are made to the platform itself.

To be clear, I'm more anti-authoritarian than a fan of either big party. If twitter's employees were 97% Republican donating I'd be saying the exact same thing.
