It's possible life existed in the Hadean epoch before the Late Heavy Bombardment, but for the most part there are no rocks from the Hadean epoch so it's difficult to say whether there was life. Those rocks were swept into the mantle. There's a tiny bit of evidence for it from isotopic ratios within Zircon crystals which have survived that long (they are robust enough to survive the mantle and resurface), but it isn't definitive.

Much like a sibling comment notes that we haven't been able to drill deep enough to find a depth without life, we haven't found rocks old enough to prove the nonexistence of life at any point in time, but if those rocks do exist they are no longer on Earth (eg they were ejected during an impact).

Fantastic for investors in Figma specifically, not so fantastic for investors in Adobe. My point is that the IPO price and subsequent price increase are not themselves proof (or even relevant) that preventing the merger was a good thing.

There most likely would have been fewer firms if the merger went through (though it could be possible that more competitors enter the market in that alternate timeline). Idk if that constitutes less competition necessarily, and competition understood as number of firms or something similar certainly doesn't always lead to better outcomes.

In the cases of "natural monopolies", consumer welfare is maximized when one firm is able to realize all the economies of scale because the benefits of mass production are so large that goods/services can only be produced at the lowest cost with sufficient consolidation. Utilities like electricity and water are often used as examples of natural monopolies.

You did say usually in fairness and I'd agree that increased competition usually leads to better outcomes. And we usually see multiple firms competing in any given industry without antitrust intervention.

I have a perspective shift that may help: Physicians are the peak of blue-collar work.

Yes, a lot of physician work involves diagnoses; but it also involves getting one’s hand dirty. Hospitals are the peak of shop and factory work.

My wife, who worked as an RN in the OR is far handier with shop tools than I am as it’s time-sensitive physical labor!

Meanwhile the jobs program are all of the white collar variety; jobs that purport to support our healthcare workers includes 100% of the health insurance companies and programs.

Thanks to a generational messaging since the 1980s and 1990s, we white collar workers have wormed our way into all aspects of industry.

No real methodology. Only my opinion.

>Can you imagine living in one of the countries that the US keeps bombing? Every time you hear an airplane you have to think if you're about to die, or someone you know is about to die, or a school is about to be blown up, or a water treatment facility.

No, I can’t imagine it. I’m not even capable of imagining it. I agree it must be terrifying, and soul-destroying in the long term.

The elephant in the room is that the fossil fuel of male loneliness is homophobia.

It's because, for decades, getting too close to another man was suspect. You hug your friend, you're "gay." You open up about your feelings? "Gay." You even care about another man? "Gay." That's the legacy. The slur is always there, hanging over you, weaponized by kids, by dads, by teachers, by sitcoms.

The structure of masculinity up until the 90s at least told boys and men that by playing the game of status, prestige, and success, you have value and most importantly, you're not women. Guys are terrified of being cast out of the "real men" club, so you end up with a whole gender refusing intimacy it's been made dangerous. There are real, tangible punishments for not playing along: mockery, exclusion, even violence.

You want to know what happens when you train an entire gender that closeness equals weakness? You get men who can't ask for help, who don’t know how to grieve, who lose their friends at 30 and never make new ones. You get men who only feel permitted to touch each other during a touchdown celebration or a bar fight.

The solution is hiding in plain sight. Vulnerability is contagious. One guy has to go first. One guy has to risk it and say "hey, I appreciate you," to hug, to call, to care, and not apologize for it. It's hard. I get it. But there's no other way out. The graveyard of failed ideas includes men's clubs, church, sports leagues, beer leagues, online communities, just hanging out. None of these address the root cause because the thing that builds friendships is connection and the thing that builds connection is closeness.

One thing you can do today that's a step in that direction? Text an acquaintance to ask how they're doing. If the thought of that feels weird, congrats you're on the right track. Connection starts with risk. Follow that North star because that's the path to getting from here to there.

> I'm not a fan of the C++26 linalg stuff.

I don't agree at all. For most, linear algebra is the primary reason they pick up C++. Up until now, the best option C++ newbies had was to go through arcane processes to onboard a high performance BLAS implementation which then requires even more arcane steps such as tuning.

With C++26, anyone can simply jump into implementing algorithms.

If anything, BLAS support was conspicuously missing from C++ (and also C).

This blend of comments is more perplexing given that a frequent criticism of C++ is its spartan standard lib, and how the selling point of some commercial software projects such as Matlab is that, unlike C++, linear algebra work is trivial.

It’s more than that actually. Where is actual interop? It’s been promised literally 10 years ago. It’s not that hard. People in Healthcare IT are just that bad.

The only time I’ve experience interop in healthcare is due to actual organizations merging. That’s it. This entire space is filled with incompetence. Maybe providers will actually use the tools if they work consistently. Food for thought.

I'm a regular in the Yosemite rock climbing scene, and Aramark is a universally despised entity for many reasons (gross negligence, outright lies, rampant neglect). One of their executives recently lost his job for hitting golf balls into Ahwahnee Meadows.

However, until people would rather camp than stay at the $600/night hotel, and cook over a campfire rather than eat overpriced food, there will always be a lucrative opportunity in Yosemite Valley that is only available to the most politically-connected companies.

Overlooked in this recap is a telling line from later in the article:

> We have no scheduled meetings, so ramblings are our equivalent of water cooler talk. We want as much deep focus time as possible, so ramblings help us stay connected while minimizing interruptions.

Emphasis in the quote is mine, to call attention specifically to the fact that this is what Obsidian is doing instead of standups.

Taken in that vein, it sounds positively miraculous to me.

Thanks! [Sorry for the delay.]

FYI: For more context, I'm trying to send a PR to Chez Scheme (and indirectly to Racket) https://github.com/cisco/ChezScheme/pull/959 to reduce expressions like

(+ 1.0 (length L)) ; ==> (+ 1.0 (fixnum->flonum (length L)))

where the "fixnums" are small integers and "flonums" are double.

It's fine, unless you have the case

(+ -0.0 (length L)) ; =wrong=> (+ -0.0 (fixnum->flonum (length L)))

because if the length is 0, it get's transformed into 0.0 instead of -0.0

There are a few corner cases, in particular because it's possible to have

(+ 1.0 x (length L))

and I really want to avoid the runtime check of (length L) == 0 if possible.

So I took a look, asked there, and now your opinion confirms what I got so far. My C is not very good, so it's nice to have a example of how the rounding directions are used. Luckily Chez Scheme only uses the default rounding and it's probably correct to cut a few corners. I'll take a looks for a few days in case there is some surprise.

That’s a better ratio than I would have expected, but I would have led with that. The title as it is written reads as a bait and switch. I initially read it as: “We paid a plurality of users $300,000 each for all of their data.”

It’s probably obvious to most readers that this isn’t what happened ($300,000 would be an absurd price for someone’s camera roll), but it feels misleading. People respond to that kind of thing really negatively here, which is probably why your post got flagged.

I want to believe that my kid is exceptional but based on grades in school and accomplishments since graduating, I'd say that she has a talent for languages and is solidly above average but not otherwise exceptional.

She has traveled a lot starting at about 6 months, and has been exposed to lots of languages and cultures. She has some Mandarin now, a little German and a lot of Japanese. So I definitely agree that her environment has supported her language acquisition.

When she was 8, she often read the same books that I read, mostly science fiction, some but not all YA. When she was 10 her class read The Oddysey in French. She was always at least a couple years ahead of her peers in reading level.

> My understanding is that the former (sucking up) is a personality trait, substantially influenced by the desire to facilitate engagement

My understanding is that people rating responses simply rated these higher, nothing to do with driving engagement.

> The latter (making up facts), I do not think is correct to ascribe to a personality trait (like compulsive liar); instead, it is because the fitness function of LLMs drive them to produce some answer and they do not know what they're talking about, but produce strings of text based on statistics.

It seems like you could perfectly describe this using personality. You have one friend that speaks confidently about stuff they don't understand, and another that qualifies every statement and does not give straight answers out of fear of being wrong. Again, this dysfunction could be attributed to what users rate higher.

I was in NYC in 2014 and had no trouble navigating the subway either. The only weird thing to me was that trains belonging to several different lines would sometimes stop at the same platform, but you get used to it quickly.

Speaking of poor navigation signage, I've been living in Saint Petersburg my whole life, and our subway system is very simple in comparison (5 lines, all transfers in the center), but the most visible signs only specify the last station for each track. More often than not, whenever I travel an unfamiliar route, I have to pause to think which station is at which end of the line. And it's me who can draw most of that map from memory. I feel sorry for the visitors.

NYC gets this right. As far as I remember, the signs said actually useful things like "Manhattan" and "Uptown and Queens".

But isn't that the goal? Regardless, the TFA posits that it's physically impossible to do what he promised to do. I'm not a rocket scientist but I got the gist of the problem (reentry is a bitch).

I'm a geek who's long been fascinated by space exploration and way back when, I drank the Elon koolaid. Knowing what he does with with his wealth puts me in the unfortunate position of cheering his failures. It sucks, but he's a threat and should not be further empowered.

What happens when naive young "Woodstock hippie" musicians tour other countries for the first time way back when digital communication was almost non-existent, and of course all parts of the world not nearly as familiar with each other as they are now?

They write a song about it :)

You know 1968 was a real fine year We've been around the world and now it's clear It's the same all over (same all over) Well it's the same all over (same all over) Well it's the same all over good people everywhere you go

I completely disagree. I don't know if it's just me or the "European mindset" but I find the NYC metro to be one of the most confusing subway systems in the world.

- You have trains that don't stop an all the stops of the line. - You have lines that share the same tracks but go to different destinations (that's okay for trains, but for a subway?!?) - You better listen to the crappy PA because if you don't you may end up in an express train, far away from where you want to go. Or pay attention to the electronic signs (if you are lucky and they work)

I think with the help of an app is usable, but I don't know how I would have managed 20 years ago

> Not all art styles throughout history valued realism.

While there is true, it's also heavily misleading wrt europes history.

The techniques really were lost in the dark ages, because the church killed everyone that was talented and didn't join their ranks, effectively wiping out a lot of knowledge (by design)

And a lot of medieval European art was clearly aimed at realism, they just weren't very good at it because they didn't know the basics.

This is "performative skepticism" with a dose of negativity bias and argument from incredulity.

"Performative skepticism is a rhetorical strategy that mimics scientific skepticism but is used to protect certain beliefs from critical examination. It often undermines evidence-based knowledge"

DOI: https://doi.org/10.34641/mg.11

Source files/code: https://mode-s.org/

Synopsis:

In the last twenty years, aircraft surveillance has moved from controller-based interrogation to automatic broadcast. The Automatic Dependent Surveillance-Broadcast (ADS-B) is one of the most common methods for aircraft to report their state information like identity, position, and speed. Like other Mode S communications, ADS-B makes use of the 1090 megahertz transponder to transmit data. The protocol for ADS-B is open, and low-cost receivers can easily be used to intercept its signals. Many recent air transportation studies have benefited from this open data source. However, the current literature does not offer a systematic exploration of Mode S and ADS-B data, nor does it explain the decoding process.

This book tackles this missing area in the literature. It offers researchers, engineers, and enthusiasts a clear guide to understanding and making use of open ADS-B and Mode S data. The first part of this book presents the knowledge required to get started with decoding these signals. It includes background information on primary radar, secondary radar, Mode A/C, Mode S, and ADS-B, as well as the hardware and software setups necessary to gather radio signals. After that, the 17 core chapters of the book investigate the details of all types of ADS-B signals and commonly used Mode S signals. Throughout these chapters, examples and sample Python code are used extensively to explain and demonstrate the decoding process. Finally, the last chapter of the book offers a summary and a brief overview of research topics that go beyond the decoding of these signals.

The game suggest - Claremont Parkway to 13 Av. Here's the map in 1964 - https://www.nycsubway.org/perl/show?/img/maps/calcagno-1967-...

I had to use google just to find Claremont Parkway on the map :) (I did find 13 av. I imagine people who this is their first time in NY would probably also be confused with 13 st)

And from the article it seems like the navigation inside the subways were also very hard - they are not intuitive even now (with some entrances only allowing one way for example, and you have to go out and back in again)

Hi, I realise I'm replying to a comment from over a week ago, but I happened across this and now I'm here.

I don't think you got what I intended with my comment. You may have missed the "they think" in the sentence you quoted, it was a bit dense. In any case, it sounds like you agree with me, if not what my comment conveyed. I agree with you.

Sure, but don't forget to look for posted signs, like:

"In Upper Manhattan, downtown 1 skips 137 St-City College, 125 St, 116 St-Columbia University, Cathedral Pkwy (110 St) and 103 St

Aug 1 - 4, Fri 9:45 PM to Mon 5:00 AM

For service to these stations, take the 1 to 96 St and transfer to an uptown 1.

For service from these stations, take the 1 to 168 St and transfer to a downtown 1." [1]

There are often many simultaneous service changes.

To some degree *all* LLM's answers are made up facts. For stuff that is abundantly present in training data those are almost always correct. For topics which are not common knowledge (allow for a great variability) you should always check.

I've started to think of LLM's as a form lossy compression of available knowledge which when prompted produces "facts".

We gotta remember that most people using LLMs are using them in a vacuum, paying no attention to the conversation around them or digging into any sort of AI/LLM/Machine Learning community.

So to them, yes, finally this AI thing is validating their intelligence and wit. It's a pretty slippery slope.

My understanding of the delayed choice experiment is that causality is preserved only because you can't actually determine the result of a single event without comparing the two results. It's spooky action at a distance, except it's temporal instead of spatial distance.

Which honestly I find to be pretty flimsy reasoning. It's almost ontological: causality is preserved because we can't prove that it isn't.

I know it's more complex than that, but it still feels like papering over a hole in our theories.

You don’t even need a financial incentive for people to start normalizing traffic violations.

Once enough people start doing something and it becomes impossible to ignore the fact that nobody is getting cited for it, the behavior spreads.

I remember traveling to a European country where drivers were angrily honking their horns at me for stopping at red lights (with no cross traffic) and stop signs.

After one close call where I was nearly rear ended because I came to a stop, I started running the stop signs (with a slow down) too.

Back home in my US city there’s a road near my house where the average speed creeps up over the course of a year until it gets so bad that a handful of drivers feel emboldened to go 30mph over the speed limit and weave through traffic.

Then the police will come out and make a show of pulling people over randomly for a few months and the behavior resets closer to the speed limit.

It really only takes 1 in 100 bad drivers believing they won’t be pulled over to make a road much more dangerous.

Maybe do something close to what I like to believe the brain does and have a meta model wrap a "base" model. The meta model gets the output data from the base model (edit: plus the original input) as input plus some meta parameters (for example the probability each token had when it was chosen and/or better which "neurons" were activated during the whole output sequence which would include the Persona they mention). It's then the meta model that generates new output data based on this input and this is the output that is shown to the user.

They can overlap with other interests and hobbies. I don’t browse UN reports directly, but I used to have access to a research service for work that would save and categorize relevant ones. Which actually makes me wonder if they are undercounting reads from other parties sharing the reports.

Who indeed matters; I’m sure for many of the reports, only several people in the world actually need to read them. I used to occasionally do research for one person to read and it was a good use of my time/salary. If it’d shared it somewhere and no one downloaded it, it would still have been worth writing for that person. However, it would’ve looked pathetic sitting out there with no downloads, compared to being printed and walked over. :)

Sometimes I wonder about the far future. Just looking at how hard it is to fight the urge by some to fell those trees for a quick buck, and seeing how preventing that requires a constant fight that comes back every 10 years and needs to be restarted all over again... It seems inevitable that at some point the stars will align and they will get their way.

I wonder, after 500 years, after 1000 years of industrialization, what will be left of Earth?
