potamic··on Rust Glancer: Rust LSP using 100x less RAM
Could you elaborate a bit on why RA's incremental approach takes more memory? Intuitively it feels that it should take less, because you're only processing what you need? Whereas you seem to indicate that you save a full analysis snapshot to disk and load it all up when needed? Shouldn't that consume the max memory for a workspace?

Fantastic project btw, and it couldn't come at a better time. With the way prices are going I really hope people start paying attention to memory again.

> Generics are convenient but they come at a cost in complexity in the type system and run-time.

By run-time they mean compile-time? There shouldn't be a run-time penalty right?

Also, is there some measure of the additional compilation cost now that generics has been added?

I dunno how it is in America, but in my country if the largest individual donor was granted carte blanche to run his own department within the administration, with his own people, answerable only to the head of the government, it would cause a helluva lot of outrage.

potamic··on India has paved the way for charging merchants a fee on UPI transactions
> someone has to pay to maintain the infrastructure

Do you know what it costs to run the cash infrastructure? Maintaining physical branches, employees to handle cash, counting machines, counterfeit detectors, security personnel, armoured transport, theft risk etc. The costs of maintaining a centralised digital infrastructure pales in comparison to this. If anything you should get a discount for using digital.

Where do you see $1B subsidy? There is no subsidy. The system is already profitable. This will generate a new revenue stream of $1B for banks out of thin air that has no reason to exist.

potamic··on Oracle bans AI-generated code from OpenJDK
> Other clues include highly structured comments with multiple headings, unnecessary comments in code, gratuitously defensive programming, and the use of emoji characters.... In general, if something in a pull request seems uncannily cheerful or meticulous then you could be looking at AI-generated content.

So, get rid of formatting, throw in an innocent grammatical mistake, intentionally omit an obscure corner case while alluding to an existential crisis for taking compromises and you're good to go!

Wasn't this the case with Einstein's relativity as well? From what I understand the maths for it was already developed for many years, but Einstein was the first to tie it all together into a cohesive theory. Ideas like there being no absolute time, speed of light being constant in all frames, seem like a pretty big conceptual leap. I don't know how scientists at the time reacted to it, but defying Newtonian laws at a time when it was considered absolutely sacrosanct, must have been a big deal.

We see the same with general relativity, with ideas like saying gravity and acceleration is the same thing. I think what really impresses people is the radical nature of these ideas, which completely upheaval long-standing, prevailing notions. To do something like that once would be pretty remarkable by itself. But to do it twice, and in both cases, resulting in a new framework that will become the basis for nearly everything else, surely must put them in the conversation for the greatest at the very least.

Leading physicists at one time appeared to disagree. Newton and Maxwell do come at #2 and #3 though.

potamic··on Cloudflare OS: an open platform for agents, apps, and work
Adopting a new technology often needs a lot of consideration. People will have a lot of questions, want to understand the implications and discuss with the hive mind. No need to attack them for that, I think.
potamic··on Show HN: Shitty – fast terminal. Memory-unsafe and faster than yours
It does seem to be quite some (very boring) work. I'm curious about your reasons for taking it up. Is it more of a principles kind of a thing or do you see it could make a difference to the project in the end?
potamic··on Show HN: Shitty – fast terminal. Memory-unsafe and faster than yours
It indeed embiggens the spirit very well.

If you're making a case of this vs what the US has interfered with, it simply does not stack up. Of course it's naive to think they won't start interfering like the US once they gain the leverage, but to a neutral party it likely doesn't matter which of these two ends up as the superpower on the global stage.

Not sure what I'm missing. If I click on Madagascar in the left box, the map zooms into Madagascar, but all the other arcs are still visible and not filtered out.

This is fantastic visualization!

I couldn't figure out from the UI but is there a way to filter the map? Say, I only want to see things going out of Cusco or I only want to see where things end up in Berlin?

It would also be nice to have some directionality to the lines to indicate source and destination, perhaps a colour or lightness gradient or something.

potamic··on Hardcore IndieWeb: Run your own website 100% independently for only $0.01/day
With a free service it's given because they have to monetize end of the day. For paid services different businesses will have different strategies. Some have a solid business model and are content with it, some want to differentiate themselves using privacy, some simply don't want to take the reputation risk that comes with moves like this. Will there be some sleazy bastards who take your money and your data (cough cough gith*)? Sure, but they will get found out eventually and astute people will be able to steer away.

He seems to suggest something like 7 hours before you go to sleep. Where did you get 3 hours?

I wonder if the same can happen from dental implants. While not subject to the same levels of mechanical stress, the mouth can be a very acidic environment which can be corrosive to metals.
