Neither Jupiter nor Saturn is close to thermal equilibrium, whereas the sun is. Bounded self-gravitating gas spheres in thermodynamic equilibrium can show negative specific heats [The classic LBLB, Lynden-Bell & Lynden-Bell, 1977 <https://adsabs.harvard.edu/full/1977MNRAS.181..405L>]. A negative specific heat capacity reducews the gas's volume as its temperature increases. Temperature in stars and gas giants is mostly lowering due to outward radiation driven by internal processes. Unlike a star, Jupiter's specific heat capacity is positive. Very roughly the sun's excess power output will cause it to grow (this handwaves a complex balance of temperature, pressure, mass, and nuclear fusion as it rises in the main-sequence part of the H-R diagram <https://chandra.harvard.edu/graphics/edu/formal/variable_sta...> -- as it climbs in that region with similar temperature the sun gets brighter because it gets bigger), while Jupiter's power output has been higher (presently about 2.5x) than its solar radiation input yet the planet has probably been shrinking.

The energy input and internal heat budgets are under active study for Jupiter <https://www.nature.com/articles/s41467-018-06107-2> (open access), and will supply further evidence for various hypotheses about "primordial Jupiter", one of which is the topic here. One of the major points of comparison with a star here would be how the former is much more like an ideal blackbody than our local gas giants. And of course there is a dark side of Jupiter, while there is no dark side of the sun.

The way it should be.

So imagine we get to Mars, establish a colony.

Mars has a day which is 24h 36m.

We could have all of our Martian colonists adhere to an Earth day of 24 hours, with sunrise and sunset drifting around the clock, or we could have them observe an extra 25th hour of the day that lasts 36 minutes.

Or, we could define the Martian day as 24 Martian hours of 60 Martian minutes of 61.5 seconds, with seconds the invariant interchange time between planets.

In turn, seconds stop being a unit of human timekeeping, and everyone just uses decimal minutes as the final subdivision.

Interestingly I’m on the other side of things, where I’ve been training NNs for quite some time and have lately been dedicating much more time to become more full stack, because most tasks these days can be solved with LLMs, which are mostly available to anyone. It does help to have a good grasp of how things work, especially embeddings, tokens, logprobs, and the likes, but I am still impresssed at how accessible and good the tooling around LLMs has become.

You don’t need much expertise in NNs to still be able to get huge value out of them today

I know of a couple of groups who have implemented their own private "internet"s because of the state of the internet proper. These aren't internet replacements in the larger sense, though, because they're entirely private and will remain so.

The basic problem is that the only way to even come close to ensuring that they are human-friendly (without causing larger problems as a side-effect, anyway) is for them to be invite-only and remain small.

> Or maybe one in the middle of the (expected) lifetime of the major release ?

This idea has been floated internally, thank you voicing this idea from the customers perspective.

It seems like the business unit believes the better idea is to just release another version. I'm not sold on more frequent releases, but I'm not in a decision maker in that area.

Came across this interesting tool: ratemycomp.tech

You plug in your base, equity, bonus, etc., and it uses AI to benchmark your total compensation against data from Blind, Levels.fyi, and other user-submitted packages. No sign-up, super fast, and surprisingly accurate (at least in my case — L5 at Amazon).

It gives you a percentile estimate instantly, and there’s an optional $5 report that breaks it down by company, level, and geography. Felt more useful than some of the paid tools I’ve seen.

Curious if anyone else here has tried it or knows who built it?

I'm a big fan of it in terms of efficacy; does wonders for headaches as well as joint aches.

My concern is about the relatively recent findings about potential Alzheimer risk [1]:

> During a median follow-up of 12.3 years, 6407 (3.0%) participants developed new-onset all-cause dementia. Participants who regularly used paracetamol had a significantly higher risk of new-onset all-cause dementia (adjusted HR, 1.18; 95%CI: 1.10-1.26), compared with non-users. However, there was no significant association between regular use of ibuprofen and new-onset all-cause dementia (users vs. non-users; adjusted HR, 1.06; 95%CI: 0.97-1.16).

I don't follow the research closely enough to know if this is reliable evidence, but there are other studies showing the same thing.

Paracetamol also well known as mood-altering, apparently inhibiting empathy [2], which may be part of why it has an analgesic effect. That isn't as scary on a personal level, but imagine a society full of millions of people on paracetamol whose ability to feel empathy has been blunted.

>It's not different from other things like databases, GPU drivers, 3D engines for games, etc.

Not quite the same. E.g. databases are a part of the system itself. It's actually pretty helpful for a SWE to understand them reasonably deeply, especially when they're so leaky as an abstraction (arguably, even the more nuanced characteristics of your database of choice will influence the design of your whole application). AI/LLMs are more like dev tooling. You don't really need to know how a text editor, compiler or IDE works.

This is one of those articles where the comments are really interesting to read through. I see a bunch of comments who don't agree with the exact math, which might be warranted, but it seems at least directionally correct to me. However there's also a bunch of people commenting that this lifestyle isn't viable for some reason or another, that mainly just boils down to a personal preference those commenters don't want to live without.

But having read through most of the objections I still find myself enticed by this. If I mentally place myself in this position I think I could quite happily live a few decades without talking to anyone for weeks or even months at a time. I'd still have my pets to give me companionship. Load my kindle up with a thousand books I want to read and just work my way through it. Pick up writing as a hobby and spend the rest of the time working at a gas station and fixing up the house and/or grow some food to offset the reduced income.

Healthcare is an issue. Doesn't seem like a viable place to grow old. Once you become too frail for physical work it's probably just time to die, which isn't great.

To be realistic and in the know, accoring to development, we are still 50 years to stable LLMs.

Data Drift. Over the course of a few moNths the data deteriorates and the LLM ceases to function in a worthwhile manner.

Currently most LLMs are based upon the core preMise that people should not believe anythiNg. This is tokenized aBove everythiNg else. Then there are other erroneous tokenizations. Why these are not fully documented, people use these tools. You should know what you are getting.

Tokenization. Different words are tokenized to have a higher value than other words or configurations.

So, these are the dangers that everyone has ignored. It makes it an unethical tool because it is based upon someone's erroneous views. Honesty is the best policy. If it cant be honest, how can you trust it?

Campo! Wow! That is some "colorful" terrain! Campo is a mere 2mi north of the Mexican border. Campo is in the middle of nowhere. Yet when you arrive in Campo, you will discover that you are still in San Diego County.

Eh, or you’ll get spied on regardless - might as well have some clue what others are doing too, so you don’t get blindsided as badly.

No matter how much everyone sings kum-ba-ya, nations have too many important reasons to spy, and very few real reasons not to. Even on allies.

If you read the marketing content on their site, the intended method of recycling these structures is to cut up the wood sections and re-use them as structural beams in regular building construction. They aren't grinding them up or melting them down or anything like that. So between the lifespan of the tower and the buildings built (or maintained) with the recycled beams, the useful lifespan of the materials used are long enough to grow new wood to replace them. At least that's my understanding.

This is obnoxiously commonplace. At my first job they upgraded me from a level N engineer (1 or 2, probably) to a level N+1 engineer with a 10% pay rise or something.

The year after that I stumbled upon a new job which paid more than their highest value of N. They definitely don't want this to happen. They want you striving for (N+1)+1 only, so they can give it out whenever they think you feel like you're not progressing, and keep you in their system.

No it wasn't. The patch removed the read of the randomness buffer that folded it into another buffer (the MD_Update calls) because Valgrind was warning that the buffer it was reading from had never been initialised.

I can't believe so many people on HN think that healthcare in the US is under the free market. Lol. For starter, can you cure a person if you're not part of the AMA cartel? You can't, the State will ruin you. Can you open an hospital without being allowed by other hospitals, your competition? In many States you can't. If you find and innovative way to organize labor, can you test it? Nope. Just the first few things that come to mind.

Healthcare in the US is much less free market than in European countries like Italy, and these are the results.

But it's amazing that people on HN din't see it, what happened to this place?

You might also like a documentary called Alone in the Wilderness, which tells the story of Dick Proenneke, a man who moved to the remote Twin Lakes region of Alaska in 1968 and lived alone in the wilderness for 30 years.

Proenneke built his own log cabin entirely by hand, using only simple tools (many of which he made himself), and filmed his daily life, including hunting, fishing, foraging, and crafting everything from scratch

> We're essentially subject to the whims of someone who is letting us do something for as long as we play nice.

Isn't that so the spirit of the times when working with LLMs? If one asks for a Prisma schema or something else out of GipPTy meant to be fed into a traditional parser, we're up the the whims of the attention blocks and layers to write out something that doesn't become a parse error. One can turn the temperature down, fine-tune, or self-host a model but does that guarantee the syntax will be correct (much less the semantics)?

You often do get cheap when you pay cheap, but paying more doesn't guarantee that you don't get the same cheap thing with a different brand on it.

Unfortunately at least two of the popular known-to-be-good brands, Aukey and RavPower, misbehaved in ways that got them banned from Amazon (IIRC fake reviews). IIRC Anker also had some scandal, recall or exploding product or other reason why I stopped trusting them (in addition to the Eufy scandal, where they released a supposedly privacy-friendly/local-only/e2ee camera that was everything but that, then lied about it for months when caught).

Same crossing, different experience: American citizen (with NY Enhanced Drivers License), Canadian First Nations (with Secure Certificate of Indian Status). They look at my native card and just wave me through.

The single time I got pulled in to go pay tax on a gift for someone ($150 USD) they looked at my card and went "I'm not dealing with the tax paperwork on that (due to some native exemptions)" and waved me back out.

As for local air travel: you'd have to go 30 minutes from Massena anyways for 'proper' air travel - Ogdensburg now has once-a-day service to DC via Breeze. Traveling to Shmoocon was hilarious for only $30 roundtrip.

> However there's also a bunch of people commenting that this lifestyle isn't viable for some reason or another, that mainly just boils down to a personal preference those commenters don't want to live without.

Given humans are also just animals that had lifestyles before money and modern society was invented, this doesn't seem like a useful distinction. Either you're talking about your personal preferences you don't want to lice without or money isn't even part of the picture in the first place. Where that line is personally drawn is just as arbitrary to this point at $1 as $1,000,000.

Overall though I agree the article sheds light where we don't normally tend to think. At the same time it crosses points too often to make that those focus of conversation. That is to say it makes a good point with just a little too much PoV twist inserted so people who don't agree will think about that statement instead. E.g. don't complain about not having the home prospects of a boomer because you can live like your great grandparent - which would be something ~40 years prior to the boomer comparison, even for a zoomer (-> driving pushback against the idea owning a house at all is the same as the lifestyle the article laments hearing about -> driving conversation like the above paragraph).

Any lessons learned from the 2024 incident? Was/is it possible to put in place internal controls to prevent future compromise?

https://news.ycombinator.com/item?id=38897363

And I guess related to the section and post on heavily and quickly adopting LLMs: Do you have any thoughts on how to ensure that sensitive customer/shareholder data is not inadvertently mixed in to some new workflow involving third-parties while keeping it accessible for production apps and services?

Keeping confidential/sensitive data from leaking into marketing workflows seems to have been a historical and relatively recent challenge for Carta so would love to hear how you were able to transition from that to securely managing the mentioned level of LLM deployment integrating across the org.

Either my code isn't commercialized so I don't mind "giving" it away, or it is commercialized but wouldn't be safe from a clean room implementation anyway. Isn't that what bigco would do of they really wanted to steal your idea?

That's great if you're in a position to be able to do it. When I had a major medical issue resulting in a five figure bill I had to pay out of pocket, I was busy with a long recovery and simply wasn't capable, mentally, physically or emotionally, of figuring out what of hoops to jump through and then jumping through them. It was an impossibility.

The meter was also a bit of a gimmick, definitionally -- they wanted a unit that was about three (French/Paris) feet, but a definition that wasn't "my personal yardstick" so everyone would agree to it.

So they played around with various definitions like the 2-second pendulum, until they found one which worked and produced a single indisputable length.

(As opposed to picking something fundamental which was unrelated to previous units. Eg (not that they could have derived it at the time), the hydrogen line, the wavelength of the 1420MHz watering hole frequency, is human scale at about 21cm/8.3 inches, fundamental throughout the universe, and unrelated to previous units.)

> Moreover, the vision that I am going to postulate here would not even require very much in the way of work. I say this because by all I have seen, many young people today find the idea of indefinite wage labor to be a dismal one. They seem to prefer a “low-work lifestyle,” but very often, the manner of living that such a lifestyle would require is completely foreign to them. Because of this, right alongside the many social media posts on the topic of the awful expense of buying a home — there are just as many posts, it seems, complaining about “life in the 4HL,” or pining for remote work, or (rightfully) bemoaning the scam-infested, difficult-to-navigate, often cynical and fake job market that they’ve encountered.

It's cheeky because it frames itself as rejecting the status quo, when actually what it is doing is saying "accept the status quo wholesale and just move to somewhere the status quo hasn't reached yet." And of course, if enough people do that, no one will be around to fight against the status quo anymore. The main difference between this and Thoreau's cabin in the woods is that Thoreau could have chosen to do differently.

> rather than acting like optimizing machines

Just because sometimes you just want a 30 second break down on how to boil pasta, or whatever, doesn't mean we're becoming "optimizing machines", just that the context matters. Sometimes I don't want to or need to know the "fundamentals of why water boils", I just need to know enough in order to complete some other thing.

> it's time to modify one's life so that it no longer matters

It sounds like you have 100% control of your own life, which might be great and all, but it isn't very realistic for most humans on the planet. Time is limited, and what we spend our time on is a choice. I too probably spend too much time learning about stuff I cannot really apply, because I like learning, but sometimes you're faced with something, you need to make a choice within N minutes/hours/days, and spending 1 month researching the topic before making a choice just isn't feasible.

What Clinton actually said:

> "You know, to just be grossly generalistic, you could put half of Trump's supporters into what I call the basket of deplorables. Right? [Laughter/applause]. The racist, sexist, homophobic, xenophobic, Islamophobic — you name it. And unfortunately there are people like that. And he has lifted them up. He has given voice to their websites that used to only have 11,000 people, now have 11 million. He tweets and retweets offensive, hateful, mean-spirited rhetoric. Now some of those folks, they are irredeemable, but thankfully they are not America.

> "But the other basket, the other basket, and I know because I see friends from all over America here. I see friends from Florida and Georgia and South Carolina and Texas, as well as you know New York and California. But that other basket of people who are people who feel that government has let them down, nobody cares about them, nobody worries about what happens to their lives and their futures, and they are just desperate for change. It doesn't really even matter where it comes from. They don't buy everything he says but he seems to hold out some hope that their lives will be different. They won't wake up and see their jobs disappear, lose a kid to heroine, feel like they're in a dead-end. Those are people we have to understand and empathize with as well."

Why, isn't that exactly the opposite meaning of how you summarized it? She literally said that these disappointed working class people who support Trump are not deplorable!

This is actually a deliberate design choice, which the breathtakingly short JSON standard explains quite well [0]. The designers deliberately didn't introduce any semantics and pushes all that to the implementors. I think this is a defensible design goal. If you introduce semantics, you're sure to annoy someone.

There's an element of "worse is better" here [1]. JSON overtook XML exactly because it's so simple and solves for the social element of communication between disparate projects with wildly different philosophies, like UNIX byte-oriented I/O streams, or like the C calling conventions.

I guess for the "backend" part it may be true, but there is a new "frontend" skillset of being able to actually implement a complex agentic workflow, and put that into a functioning product, which can be a lot of code. So closer to web dev in the end. I have nothing against button clicking if it does work, as it may be a sign of maturity for a technical field. I click on a button in my car and turn a wheel and it usually go where I want, feels great. The equivalent would be the Microsoft ecosystem here.
