Why is it that some systems come to equilibrium quickly, effectively erasing the imprint of initial conditions, while others do not?

For instance, if we look at the distribution of astronomical bodies in the universe, almost nothing can be understood without knowing the initial conditions. Or, to take the other side of the coin: by studying the present day state of astronomical bodies, we can infer quite a bit about the initial conditions of the universe. Whereas, knowing a later state of the balls in the video tells us almost nothing about where the initial ball drop occurred.

Perhaps the answer is “chaotic dynamics”. Yet gravitational interactions can certainly be chaotic. And some chaotic systems still don’t “come to equilibrium”.

I suppose I’m asking how one might look at the dynamical laws at a glance and say one system will come to equilibrium and another will not.
I'm not getting great results. It seems to love to latch on to a keyword in the question and run with it (maybe the GPT-4 version does better). I asked a question about async in Rust, it gave me a comparison between threads and async and then kept going in that direction instead of answering what I asked. I mentioned a specific crate as something I wanted an alternative to, and it told me a description of the crate. Rephrasing the question a few times eventually got a correct answer, but it's not much better than going straight to ChatGPT.
Oh. Hadn't thought of Gitea in a while. Will check it out. Thx for the reply!
>I wonder if there is potentially an issue with them in aggregate. Such that the dose of any single chemical isn't problematic but all of them together with similar effects causes a problem.

I've been wondering about this a lot in recent years.
Particularly in regards to medications/pharmaceuticals but also environmental containments/traces (which can include pharmaceuticals of course), pair with this what we are just starting to understand about plastics exposure and pervasiveness and I really wonder why more health research and workplace safety resources aren't being directed to look at compound and long term exposures.
Any updates on the situation in 2023?
Important to note that any appreciable amount of home charging makes it a lot harder for gas to beat EVs or PHEVs most places and my calculations above are for 100% fast charging. PHEVs are hard to calculate for because where they land between hybrids and full EVs is basically entirely dependent on the user but the upshot (ignoring emissions) is that the best PHEVs aren't much worse than the best hybrids or the best EVs so you can choose the cheapest fuel on a day-to-day basis and potentially come out ahead.

"Available" is a generous word. It's actually pretty hard to find even from underground anabolic steroid sellers. The only reason I was able to get my hands on it was because a seller was getting rid of his stock. The main reason is that it's actually pretty crummy for fat loss. If you actually want to lose weight you'd probably be pointed to a low dose of hgh, which has a ton of other benefits to help you lose fat.
How is that different from mirroring? I just meant the same content is available on multiple domains.
Yes, in theory the GM's EV-1 beat them to market by a lot. But in real terms Tesla had the EV market cornered for years. The only real competition was the Leaf and Bolt, and even those were low volume vehicles. It remains to be seen if the legacy automakers can successfully ramp production this year. They have made a lot of promises, but actual deliveries are still lagging.
Yeah, I’ve noticed this recently. As I spend more time with my current friend group in the new city I live in, the worse I feel because it seems like we’re just surface level friends, whereas when I spend time with my friends back home it greatly lifts my spirits because it’s a genuine connection.

It’s a an extremely odd feeling because from the outside I’m sure it looks like I have a great social life and good friends, but I’ve never felt more alone in my life. And I’m not sure how to address this conundrum, on one hand I want a stronger friendship with this new group of friends and don’t want to be alone, but at the same time it seems as if I would be happier if I disconnected myself from the group and was actually alone.
We probably SHOULD ban all farming in California, simply to improve the conditions of rural communities that used to farm but can't profitably compete anymore. We could use a revival of some blue collar communities, and the only losers would be agribusiness in california, to which I say, don't create a farming company in the desert maybe.
This is why you can do

const true = false

in golang

The number of reserved keywords is not a bad thing. For example, I constantly missed `final` when I worked in golang. Just because a keyword doesn't exist does not make its usecase disappear. Same with other features like `enum` (extremely useful) and visibility rules. golang only has package private and public, not nearly as granular as one needs in practice, not to mention generating large CL's when changing the visibility rules of a function, as opposed to simply having a 1 line change. Sure you can ignore those use cases, but it doesn't mean that their usefulness disappears.
i mean its also particularly churny. there's no "one standard way to do things" anymore. every framework/open source app launch now has to include instructions for like 4 different deploy targets because people can barely even standardize on helm charts much less how to orchestrate containers without k8s/docker compose (every newroku startup seems to want to reinvent the docker compose file, render included)

Counterpoint:

Humanity has to cope with these little things called ethics, morality, and empathy. While it may be the definition of evolutionary "unfitness" in the scientific sense, the ability to exercise foresight, to predict the suffering coming from one's behavior, being averse to bringing a life into the world without having a reasonable answer to the issues you can reasonably forsee, and having the will to act on said understanding are all socially desirable traits that also fly in the face of natural selection.

In a conflict over livability and finite resources unrestrained growth is a losing game for everyone, guaranteed. The only variable is when.
If you priced agricultural water at levels comparable to residential use, and mandated water conservation efforts with similar cost per gallon lost, that would be the same thing as banning farming in the California desert.
Meh. Lets not pretend like a 16 year old signing papers to join the army was too dumb to understand it meant they were joining the army. 16 is hardly fingers-in-the-wall-socket level of understanding the world.
I think the definitions are useful here - a script is part of a program, and a program gives structure to a large script or to many loosely related scripts (I think of the paper program you receive at a performance). Thus everyone is right, a script is a program (with just one script), and a program is just a large script, or a collection of many scripts.

Much of this wording likely derives from plays and performances (also see Actors in computer science):

[0] Program (https://www.merriam-webster.com/dictionary/program): I think the 2nd or 3rd definition is best here (as the later definitions actually refer to computer programs, but don't cut to my proposed etymology) - "2. a: a brief usually printed outline of the order to be followed, of the features to be presented, and the persons participating (as in a public performance)".

[1] Script (https://www.merriam-webster.com/dictionary/script): I think 1c2 again is most relevant here, as it is likely the root of its usage in computers - "1. c (2): the written text of a stage play, screenplay, or broadcast... specifically: the one used in production or performance".
I think they are naked because they don't have 'private parts' to display. They are sexless creatures who multiply by cloning themselves, instead of having sex / courting.

And other theories suggest they interbred with us, and that we are hybrids.

I'm sorry, we don't have any examples in the article about adding values to enums, so I don't know to what you are referring here.

> Yes, that's true, but also very rare?

It is rare, indeed, but we just have a strong inclination towards having a clean schema, so we do prefer to clean up things that would otherwise be unused. But I understand that many people would prefer to leave them hanging there, even if they are not going to be used in any way.
It sounds you're conflating an older framework with Java the language.
> How much of the previous disruptions came with actual improvements to the user experience? Or at least something novel?

I think that's one of my biggest critiques with the commonly suggest Reddit alternatives. They seem to not be offering much innovation in the space.

I've been working on a platform that's sort of like a Reddit/Discord/Patreon hybrid that combines the feature set of Discord with the discovery and threaded style of discussion of Reddit with the monetization ability of Patreon.

Here's an example community:

I am not pleased with Microsoft. Yes, there have been some improvements. But GitHub Actions is very half baked, yet the bean counters at my company are asking "why do we pay for buildkite?". It feels like they are using the same playbook as MS Teams.
i frown on anything JS because it always end up requiring some sort of 'npm install' or, shivers, 'npm install -g'. it's just as bad a running a random 4gb java binary with extra steps.

js will only run on users machines or inside a vm without even kvm because we've seen plent ecosystem hijacks and exploits in the wild already. and you can only fool me MAX_INT.
Maybe so, but I would consider the "net good" of an institution, since most if not all institutions have at least some bad elements.

I don't believe that was the intent of your parent. The 6 hours of tattooing was instead a scenario they have personally experienced where they have also observed others having wildly divergent experiences from themselves, despite the same inputs, and are using that to bootstrap a framework for understanding how wildly different others' experiences with hunger might be from their own.

It definitely belies a level of privilege that some people must intentionally seek out discomfort or pain in order to begin to even approximate the agony others are inherently forced to live through. I don't believe privilege is itself a moral failing, or we're stuck with whole categories of 'original sin'. It's what objectives its used to enable that potentially indict those that possess it.

Ask HN: What to do when feeling low-energy/tired during the day?
I thought it might be interesting to hear what helped others. I'd consider my lifestyle pretty healthy and my sleep is good, but I often feel low-energy during the day.

- I'm exercising a lot (usually 5 days a week)

- I'm drinking coffee (2-3 cups in the morning)

- I'm getting about 7 hours of sleep per night

Is there anything specific that I should try or get checked?

As you point out, not all commands support this convention and the author feels that it would be hard to enforce this consistently among maintainers. I agree that it would be easier (for me) to remember to prefix globs with `./`.
It's possible that if a current 100 IQ society doesn't notice the trend, then future 90 IQ won't notice the ever worsening, nor will the next 80 IQ...
That would be the equivalent of flying Sidney, Australia to Los Angeles, landing at the airport, and crashing 10 feet away from the gate.

Perhaps it is assumed most people won't think about these questions and just accept the FUD fear uncertainty and doubt? Often crashing around military sites would suggest to me a way to cover up failed prototype craft that are being demonstrated to potential buyers.

Also, can't they wear clothes ? Looks like the only aliens we have here on Earth are little greens or little grays, but one thing in common: always naked.

Psychological effect perhaps? Fear makes people talk about a thing. I don't know why this would be done given this would not be useful for getting space defense funding. We barely spend anything on watching for dangerous asteroids and that is not even a theoretical risk. Maybe it's as simple as distracting from current events? I would expect visitors to be in space suits that double as armor to protect from the risk of not being accepted and to allow for acclimation to or isolation from our atmosphere. The carvings all around the world on megaliths suggest that previous visitors wore space suits that had pseudo-wings and tanks but maybe they were just smoking some funny stuff or perhaps those were not aliens but just our own advanced civilization that mostly destroyed itself.
This style of AI doesn't generate value, it extracts value. You can deliver a 90% as good product for 10% of the cost. That's great for the person arbitraging the 90% savings, but worse for anyone actually using the service. In this regard it functions primarily as a wealth transfer mechanism, so it ends up like blockchains anyway.
Because of course there's so little to worry about with storing vast reams of medical data from real people in cloud systems (that surely never get breached) to be accessed by AIs that surely will never create data privacy problems from all the ML vacuuming they rely on....
I find their use of the word "subgroup" here to be annoying, because a subgroup under their semantics "inherits" members from the group it's included in, i.e. the cardinality of a subgroup is _larger_ than the cardinality of its parent.

Emotions aren't the truth. This is just a particular psychological hangup.

> In that world, Tesla would have had to switch their cars over to CCS eventually and retrofit their existing chargers to CCS, and people who bought Teslas with the proprietary plug have a terrible UX of needing adapters everywhere.

It should be noted that in any case Tesla will have to support CCS, though in its CCS2 version. It is the de facto standard in Europe and is in the process of making their chargers in Europe fully compatible since the M3 comes with CCS2 by default here. And it is unlikely to change any time soon, CHAdeMO is dying here and all the other networks are using CCS2 (which seems to be much better than CCS1 if I trust the complaints about CCS1 I read on HN).
I'm not. The biggest enemy of Linux/FOSS should never have been in charge of the biggest repository of open source software.
Also got an email but interestingly the most populated group I'm a member of has 4 users in it including myself. It did mention that my "top-level" group has reached the 5-member limit but it references a numerical ID that doesn't match my user or any of the groups I'm member to.

There may be a glitch with this rollout.
Huh. Ok, so... what is it? Like a legally binding agreement your employers would typically give you?

I've never seen (or even heard) of such a thing. What's in it? Like does it guarantee you a job for a certain amount of time, or how does it work? If the renege on it, can you sue them...?

And if it's relevant... can I ask what field/vertical you work in?
The Model Y seems to be their real killer product. The Model 3 is a solid #2 for the business.
Arguably, those are !NACS at all. It wasn't called NACS until the specs were delivered, along with the requirement to support CCS signaling.
I like this comparison. A ton of dotcom-era stuff was "the same tech, applied to different industries" - that's actually common for a lot of cycles, by nature. And there are going to be winners and losers, but it's likely you have a lot of application-specific winners that emerge (vs JUST OpenAI/MS/whoever) as well as a fleet of also-rans.

This also doesn't at all require ChatGPT to be the first step on a road to self-aware sentient AI or anything else like that - the tools being built today will already disrupt a lot of things enough to allow for new winners and losers.
I don't know that I'd call it kafka-esque but I think they make a good point about friction - the signup process also includes learning about this new thing, which is going to throw people.

Especially, I think, because there is a gulf between what the service intends to be and what people want it to be.
> The tests kept coming back normal. Neurologists referred him to psychiatrists. Psychiatrists referred him back to neurologists. Pediatricians recommended therapists. Therapists suggested psychologists.

Oh boy are cycles like this familiar. I remember when a respirologist referred me to a psychologist for my inability to take good breaths. "Stress" (i.e. hypochondria probably)

Well eventually a gastroenterologist realized it was stomach acid bubbling up into my throat or something like that. I've been on Nexium for 15 years now, and I can breathe just fine.
Unclear on why the other comment was flagged, I'll pull just the facts through to this one.

> It's office space that's situated conveniently close to Parliament, and isn't just used by conservative think tanks. For example, Feeding Britain (https://feedingbritain.org), a charity dedicated towards solving hunger in the UK, and headed by the Archbishop of Canterbury, is also based at this address.

This is an extremely selective statement, there are 9 businesses stationed at 55 Tufton street and every other bar Feeding Britain is controversial. Some have links to far right populist ventures, even the other charities like the Taxpayer's Alliance actually "[exploit] the taxpayer rather than protecting their interests as they claim to do"[1]

> As for the rest of your comment, please read: https://lgballiance.org.uk/lgb-alliance-who-what-why-when/

Rather than going to the LGB alliance's site to read who they say they are, I'd rather believe in their actions over their words.

* They have argued it is not homophobic to oppose same sex marriage

* They have argued against a ban on conversion therapy for trans people

* They have suggested the "+" on "LGBTQ+" promotes beastiality

* They specifically excluded the names of trans victims from their condolences list after the Colorado Springs night club shooting

Fifty LGBT organisations pushed back against the LGB alliance being given charitable status. Plenty more have branded them a hate group. I think these longer lasting perspectives are far more telling than the autobiography from a group who came into existence in 2019.

Not just push mirrors but pull mirrors and push+pull mirrors. I frequently use the pull mirrors to backup repos that I don't trust to stay around (either because they might break a TOS or be right on the line, or i expect the author to not leave it around for some reason). It's definitely become one of my "must have" for any kind of local hosting stuff esp since the docker images make it basically painless to deploy.
In the US, most apartment dwellers park in a garage, which can and will be retrofitted with chargers. Street parking is the major challenge. In Park Slope Brooklyn, I often see a lone cable coming out of a brownstone out to a Tesla on the street. :-)
>If they were to build this capability and experience fulfilling social interactions, they'd find themselves wanting more of it and therefore become less lonely.

According to the GP, by wanting more fulfilling social interactions they'll become more lonely, not less. Just because you want something doesn't mean you'll get it. If someone can only afford cheap junk food but that's all they know, the last thing you should do is show them gourmet food so they know what they're missing out on.

> traffic is pretty consistent everywhere.

Yes, accidents always happen in the same spot at the same time on the same days, and new people visiting new places always know about those things.

I have had Google try to send me on slower routes, but I use my brain and drive the more logical way and it updates the map accordingly. Though most people are not logical, and such practices theoretically help everyone overall including the petson who is sent on a different route that time.
> it's not going to die, but it will be less popular and less relevant

That more or less _is_ death for a social media thing, though, because it tends to become self-reinforcing.
What about RSS eliminates tracking? Refreshing the feed is exactly the same HTTP request as fetching a page.

With RSS you have to make the request periodically to stay up to date, so I'd say you trade some of that temporal tracking for extra geotracking.

As someone who works at the Co -- If you are within the free usage limits, we are fine with you mirroring a repo on .com.

Okay but, again, this is a waaay higher standard to place on a fat person than a thin person just because they're fat. As a thin person I never have to "learn to live with" somewhat hungry forever and I think expecting fat people to is stupid. I never have to decide whether or not a lifetime of hunger is worth 5 extra years of life, or if my hunger isn't so bad I can tune it out. That's a standard I don't hold myself to as a thin person, why would I hold a fat person to that standard?
It’s not that hard to setup. It’s a built-in feature in something like gitea. Or you can write a `git push` cron task or a server hook in git to keep the 2 in sync. GitHub is full of mirror repos. You can also disable issues, discussions, wiki, and pull requests if you don’t want to deal with that.
