  • It’s always good to support the original publisher and encourage local libraries by reading a hard copy, so I could never endorse piracy, even for people who can’t get their hands on a physical copy. Even though it’s true that both libgen and annas-archive have ebook copies of this particular book (and can easily be found via google), I could never in good conscience direct anyone to such a site.



  • Are you set on using light sources, or would you be okay with a shader that just creates the shadows without checking for specific light sources? It looks like this might do what you want, but you might need to modify it to work with your exact use case (multiple z levels).

    Generally it seems like some kind of shader might be your best option, it seems like the 2d lights are intended for casting lights within a given z level rather than between them. If you want more complex shadows across multiple z levels, you might need to create your own light objects (just a position, color, and intensity) and pass them to a shader that does something similar to the linked example, but modified based on your lights list.

    It’s possible there’s a simpler way that someone else could chime in with (I’m pretty new to godot), but as far as I can tell the built in 2d light and shadow systems aren’t designed for different z levels, so you’d need to use something else.





  • I was curious to learn more about this, because it sounded interesting, so I googled it. I’m guessing you’re talking about the interstitium? There’s a lot of criticism of that episode for inaccuracies about the interstitium (known for much longer than the 5 years the episode claims - it’s been mainstream since at least the 80s), traditional Chinese medicine (the treatments they mention have been proven to be no more effective than a placebo) and the connection between the two (there’s no relation between the interstitium and the lines predicted by chi). Everyone in the discussions I found sounded pretty disappointed in the episode.

    Even if it’s usually pretty accurate (I don’t actually know whether it is), radiolab is not the same thing as the scientific establishment, and this is probably why the OP asked if anyone who does science for a living rather than reading pop science articles could reply.

    For anyone else who was curious about lichens covering “a not insignificant amount” of the earth’s surface, a quick google tells me it’s about 7% (according to e.g. new york times, scientific american, etc)

    Edit: oh and estimating the age of an exposed surface by lichen diameter is called lichenometry. I’m seeing stuff about it being used in geological contexts but it makes sense that it could work for old buildings too

    Probably Wayne Gretzky? I don’t even know anything about ice hockey and I know he’s supposed to be the most dominant player of any sport. Like he and his brother have the record for highest combined goals of any pair of brothers: 2,857 by Wayne, 4 by Brent. If you take away all his goals, he’d be the highest scoring player of all time on assists alone. There have been 13 times when a player has scored over 100 goals in a season in NHL history: Lemieux (once), Orr (once), and Gretzy (eleven times in a row). He retired last century and still holds 57 records. I’m not gonna keep picking out examples but there’s a bunch more facts like this that sound like the old “chuck norris facts” meme but are actually true.

    “If you don’t know anything about ice hockey why do you have all these facts on hand?” - I remembered seeing this kind of list before so I did a quick Google.

    Edit: I’m seeing some different exact figures for some of these, but the general principle stands and I’m not invested enough in hockey facts to nail down which numbers are exactly right.
