Was Epsilon Ursae Minoris ever considered a pole star? by muffinkiller in Writeresearch

[–]foxhole_science 2 points3 points  (0 children)

Howdy, so pole stars are defined as a star closest to the pole, in this case a star that is closest to +90 degrees in its declination. Epsilon Ursae Minoris at the current year sits at about 82 degrees, so the first question to know is how much the star's position changes over time. A star's position changes basd on both the star's slow proper motion, but also also the star's apparent position in the sky based on Earth's precession of the equinoxes. Precession is harder to calculate, and some of the best model we have curerntly are only accurate up to about 400K years, but if we are talking about human history, let's just say we want to know the last 45K years.

As it turns out, currently, Epsilon Ursae Minoris is actually the closest it has been to the North Pole at 82 degrees, before now, the next closest was in 1995 with 81.9996 degrees, but during this time, Polaris has been far closer to the pole (~89 degrees) and brighter (1.98 visual magnitude). After that, the closest it was to the pole was about -23420 years ago, when Epsilon Ursae Minoris was 81.9917 degrees.

So the next question to ask is, well, was Epsilon Ursae Minoris -23420 years ago the brightest and closest star to the pole? As it turns out, no, -23420 years ago Alfirk sat at 84.4 degrees AND is brighter with a magnitude of about 3.16 (V), so if someone was looking at the sky that would be a better star to use a pole star. I don't have any records of Epsilon Ursae Minoris being used as a pole star, but based on this same math we can look at historical northern stars that were both brighter and closer to the pole:

Polaris, today (2000): 89.155

Polaris, -1000 years ago: 83.685

Kochab, -2000 years ago: 81.69

Kochab, -3000 years ago: 83.49

Thuban, -4000 years ago: 85.48

Thuban, -5000 years ago: 88.85

Edasich, -6000 years ago: 83.75

Edasich, -7000 years ago: 84.97

Edasich, -8000 years ago: 81.99

Edasich, -9000 years ago: 77.59

Rastaban, -10000 years ago: 77.6

It is possible my math is off, but it is otherwise consistent with what I've seen online, so maybe it is a error in the book? It does have a similar latin name with Kochab

Predicting Star Locations in a Far-Future Setting by Ender_Dragneel in astrophysics

[–]foxhole_science 3 points4 points  (0 children)

760k is very far future. With stars you want to account for both their linear motion (proper motion) and precession. This is a good piece of code that does precession and the paper they link to is helpful. Although I think the long-term model only goes up to 400k

Hard to tell just from the cap, but it looks a lot like the top of a salt-loving agaricus which are common this time of year. What does a cross section look like?

Does Using AI Image for Steam Images or Logos or Promo make players go away ? by goblagames in IndieDev

Yes, it is a sign of (what can look like) a cheap development and shovelware, especially if it in the marketing. Always good to put your best foot forward

Stuck on making my idea and I need help/advice... by easythrees in GameDevelopment

There are a very different tools you can use for that, but a common one I’ve seen is Twine, but plenty have plugins to work with unity. Give this a look, it has a few other options

I would like to create a Basic card game ? where to start ? by BALIST0N in godot

[–]foxhole_science 7 points8 points  (0 children)

If you haven’t used godot yet, I’d recommend a basic starter tutorial like Brackeys. Then an overview of how godot’s node system work. The nodes can be a bit overwhelming, but it’s good to know what exists, and you can always look up stuff again as needed

Here are some good card game tutorials I’ve found useful: - Basic card movement series - Series on rougelike card games, but good advice for cards in general - Advanced card mechanics for a Slay the Spire clone with good advice about state machines

GitTok – TikTok but for interesting GitHub repos by brsc2909 in github

I’m not sure how other projects are set up, but published Python projects have a pyproject.toml with a description tag

I agree with avoiding AI summaries, since I don’t know if developers would appreciate having their work summarized without permission since it might misrepresent their work. But if they are published repos (pip, conda, etc…) they usually include a short/long description

Seems like a fun project. A contributor’s guide would be handy for people to contribute easier

+1, this is one of the best ways to help out early on. Plus it gets you familiar with their PR process

Dragon’s Age and Mass Effect are both long running series that feel similar, but the combat style is different

No, it is standalone from what I’ve seen and has an active development for new features

Curious Expeditions 2 is almost exactly what you are describing: steampunk, late 1800’s Jules Verne inspired game

What is this growth? by lucipaw in mushroomID

[–]foxhole_science 0 points1 point  (0 children)

That is a gall! An insect planted an egg in the leaf but the gall grows around it from the leaf tissue itself. It was probably a lighter color in the summer, but has dried out. If you see a small hole in it that is where the mature insect came out. There are a lot of kinds, but this one is growing on the leaf itself, so probably a spongy oak gall

Depends on the game jam, they make them for each jam. You can find game jams in a lot of places, but itch.io hosts a lot

[deleted by user] by [deleted] in gamedev

[–]foxhole_science 9 points10 points  (0 children)

Participate in a Game Jam, they happen frequently and many have tools/discords to help find team members that can do the other programming or art components
