  • What do you do? You can’t detain the girl. So she leaves and what? You call the cops and say “I fucked up and hit someone with my van.” Who does that help? Now shes lost in the crowd. You can’t just stay there, so you drive away. What else is there to do?

    Even if every charitable assumption you’ve made is correct, you and every reasonable person knows exactly what he should have done.

    You said it yourself. You man up, you call the cops, you tell them “I fucked up and hit someone with my van”, and that there is a human being that needs help. That’s it. That’s what you do. That’s what every single person should have done.

    It seems to me you’re trying to engage in healthy dialogue, but “That’s a ragebait title” is just not true; the headline does, in fact, summarize events rather well.

    The adult, the driver of the car, that hit and injured another human, let alone a kid, bears 100% of blame and took none of the responsibility.


  • Someone needs to DM to remind me (if you’re interested), but I built a pretty clever stack with all the arrs, a failsafe vpn network tunnel, dynamic dns, deluge, Jellyfin, jellyseer, reverse proxy. The works.

    It’s dead simple to use (my mother runs it no problem). There is a semi-manual setup process, but a few mildly tech literate friends got it running in a couple hours.

    Built for Windows, all deployed on docker. Works fine on Linux/Mac also.

    The reason I’m not sharing it in this comment is I never intended to share it publicly and want to ensure my repo is sanitized of any PII.

    If you’d like, hit me up sometime.

    What gets me about this photo is how fundamentally unserious the whole scene appears. The body language of nearly everyone, the lack of focus, the shabbiness of it all… just embarrassing. I’ve seen high school clubs looking more competent and serious.

    I know this is just an aesthetics thing, but it gets to me. 🤷









  • I’m not a geologist but I’ve read up on it a fair bit.

    This Mars photo appears to be sandstone.

    On earth sandstone is usually associated with ancient rivers, lake shores, and sea shores. But also sand dune fields.

    The thing with sandstone though, is it’s not just sand. Rather, it’s sand plus time plus pressure plus cementation.

    Now, the time part is obvious. What’s sandstone now was sand a long ass time ago (usually).

    Pressure? That’s a little harder to understand for me here. Has mars ever had tectonic stuff going on to bury it (and hence have pressure applied), followed by erosion and uplift? Or am I incorrect and pressure is not a necessary condition? Maybe sandstone without pressure is a thing it’s just weaker and/or less dense? Maybe layers of volcanic basalt or something could have a similar effect? I don’t know and would love to have someone more knowledgeable fill this part out.

    Cementation? This part, I’m nearly certain, REQUIRES water. On earth anyway, this happens when ground water absorbs chemicals from other rock/stuff (for example carbonates from sea shells, but there’s lots of other chemicals that can do this), then flows through the beds of buried sand, and some of those chemicals are deposited along with magical chemistry stuff happening, and your sand becomes sand stone.

    So I don’t 100% know that the short answer to your question is “yes”, but I’m leaning towards a solid “yeah, probably, but I’m not a real geologist and Mars isn’t a real Earth so I dunno”.









  • I can try to explain, but there are people who know much more about this stuff than I do, so hopefully someone more knowledgeable steps in to check my work.

    What does ‘random’ or ‘noise’ mean? In this context, random means that any given bit of information is equally as likely to be a 1 or a 0. Noise means a collection of information that is either random or unimportant/non-useful.

    So, you say “Compression saves on redundant data”. Well, if we think that through, and consider the definitions I’ve given above, we will reason that ‘random noise’ either doesn’t have redundant information (due to the randomness), or that much of the information is not useful (due to its characteristic as noise).

    I think that’s what the person is describing. Does that help?


  • I’m not an Information Theory guy, but I am aware that, regardless of how clever one might hope to be, there is a theoretical limit on how compressed any given set of information could possibly be; and this is particularly true for the lossless compression demanded by this challenge.

    Quote from the article:

    The skepticism is well-founded, said Karl Martin, chief technology officer of data science company Integrate.ai. Martin’s PhD thesis at the University of Toronto focused on data compression and security.

    Neuralink’s brainwave signals are compressible at ratios of around 2 to 1 and up to 7 to 1, he said in an email. But 200 to 1 “is far beyond what we expect to be the fundamental limit of possibility.”









  • It’s not just a fat or muscle thing. Those both contribute of course; fat insulates and muscle produces more heat. But the real player is the surface area to volume ratio.

    A bigger person has a lot more volume than they have a bigger surface area, and since heat is lost through the skin this has a major impact.
