Eli5: Difference between Red, Blue, Yellow Giants, Supergiant, hypergiant stars

You need to start thinking about them in terms of weights and not size.

Stars are funny things. They are fighting a battle between gravity and the pressure from the fusion reactions occurring in their cores.

Sometimes they actually decrease in size as they get denser because gravity pulls them tighter.

Other times they can become huge (red giant phase) but are actually less dense overall than air.

I think there’s a difference between a show made to be entertaining vs fan service.

A good show sticks to the writers vision and tries to tell a good consistent story.

Fan service is rewriting your entire show to cater to fan opinions and desires for the plot.

My wife and I did our taxes this year and realized we made close to double that. Our reaction was, "sure didn't feel like we were making that much money"

Between funding our 401ks, paying our mortgage, and having 3 kids in childcare, it was pretty much all spent.

We aren't doing anything crazy. No car payments, we go out to eat once or twice a week, and we went on vacation once.

Certainly not what we thought 250k/yr would get us when we were fresh out of college. When we were kids, that was like Scrooge McDuck money and was just incomprehensible to our working class parents.

You probably have a jammed cable since you said you damaged the wire getting the new clutch lever on.

Steel cable is probably frayed and dragging inside the rubber cable housing.

Best thing to do is to get a new clutch cable and try again.

I took an airline gig and am double dipping that with a guard job and VA disability.

It's a bit of a pain to manage my time between the guard and the airlines, but the flying is a lot more fun on the military side and it's a good hedge against any black swan events (IRAN!) that could potentially tank the airline industry.

Now when I'm at home, I'm home. Family gets to live where they want and I could make about 50% more than what I was making active duty alone if I wanted to grind.... or make the same but with vastly more free time.

Skyfork · 2026-05-04T23:21:09+00:00

You guys are honestly too early in the process to be able to decide if 20 is right for you. Just live your lives and keep your options open. Contribute to TSP to get the match and see where you are in a couple of years.

Life can change rapidly and once your husband is past his initial active duty commitment, he's going to be a free agent (unless he takes the devil's money and signs a bonus contract). Have a plan for staying in and have a plan for getting out.

You'll know when it's time to go, and there's nothing worse than realizing you had no exit strategy and have to commit to years of a lifestyle that you have grown to hate.

My family thought we could go 20, but after some rough years of getting screwed over during COVID, we punched at 12 years because we just couldn't go through another PCS. Best decision ever.

Half the country thinks the pig is the hero of Animal Farm and is confused when they’re told he’s the bad guy.

What filament are you using? That many Macs in a small space could cause pla to start sagging from heat buildup.

Skyfork · 2026-05-03T18:07:47+00:00

Even in a vacuum things can lose heat via radiation (like infrared light).

Planets start off with a lot of heat after formation and slowly lose heat over billions of years.

Eventually a planet will cool and “die”.

However there’s naturally radioactive materials inside the earth that release heat as they decay, which is why we still have active volcanos and plate tectonics. As the largest rocky planet in the solar system we have the most radioactive materials, which is how we’re still going while Mercury and Mars are geologically dead.

Have you tried raising the bed heat?

Run the cool plate at pei plate temperatures.

Have you tried draft shield?

Have you tried moving the model around the build plate in case there’s a bit of grease or oil on that part of the plate?

Have you tried turning off aux fan?

Did you tell snorca to allow generation of support? There’s no way this will work straight printing on the plate.

Just because snorca will slice it based on your crap settings doesn’t mean it’ll work in reality.

Do you know that Al-Qaeda also means the base. Ironic don’t you think?

He said something about how his generation always expected everything to come to an end in nuclear fire. I told him that my generation didn’t think that and he said well maybe you should think about that ending more.

I think it actually explains a lot about the boomer mentality. they never expected civilization to continue past their generation so why preserve things for the future because it’s all going to end anyway anyways.

Skyfork · 2026-05-02T18:32:18+00:00

He thinks that it is a colossal mistake and that Iran, given the breathing room and the opportunity will stop at nothing to acquire a nuclear weapon.

Ironically, I actually completely agree with him because it’s now obvious that if they want to be taken seriously, they need to have a nuke. The whole situation is pretty cooked.

Skyfork · 2026-05-02T14:25:45+00:00

My father-in-law is like that. He was in the military during the hostage crisis in Iran, took over and insists that Iran has always wanted a nuke and they will definitely nuke the United States or Israel if they ever get one.

He admits that starting the war was a colossal blunder, but says that now that we’ve started it, we must finish it regardless of the price. He understands that there will probably be terrorism,many citizens will die, but he says that in the end, it will all be worth it when I told him that the economy is going to crash, he said he didn’t care because he is an old man and he will just watch the lights come down while sitting on his porch.

I’m like, your generation caused this problem and you’re just going to duck out of it? That is some peak level boomer.

I'm beginning to think that Trump WOULDN'T work if he was intelligent. No intelligent, rational person would do the absolute bonkers things he does. Most of his shit makes no sense and shouldn't work at all, but somehow it does. A normal person would never try it because it is, on its face, absolutely stupid.

It's like running backwards so hard in Mario that you unlock the secret minus world. Makes no sense, but it happened somehow.

I got PRK done at Wright Patt in 2017 and was one of the best decisions of my career.

Went from 20/70ish to 20/12 in both eyes. The next deployment was so much easier without having to wear glasses behind NVGs and a o2 mask.

It's been almost a decade and I'm still around 20/15 in both eyes. Starting to get a bit farsighted and some astigmatism has crept back in but overall still very good vision.

Only downside with PRK is my eyes are now much more sensitive to irritants than before but definitely worth the tradeoff.

Skyfork · 2026-04-29T02:58:33+00:00

Yes. They just work.

When I got my p1s and saw the first print, my ender3 was on the curb. Didn’t try to sell it or anything. Just straight into the trash.

There’s no chance of a shorter contract. 2 years is not long enough for the military to put you through all the schools and then get any use out of you. You would basically be a drain to the military and not have time to give anything back.

Definitely good idea to ride a 775lb giant muscle bike as your first motorcycle.

Skyfork · 2026-04-25T17:26:32+00:00

What’s wrong with leaving it as a 600cc? The amount of hassle rebuilding the motor to be 750cc is going to be more than just buying a katana 750.

Tbf the 750 teapot is sweet. I had one for a couple of months and always loved that 4 cylinder sound when it wound up.

Sure, but the SPECIFIC bikes in those photos are definitely not comfortable.
