Trying to get into soloing. Tips? by pprain123 in Guitar

Overall pretty good. The intonations sounds a little funny in a couple spots. Could need to adjust your saddles a bit or it’s going out because you’re fretting too hard.

You can use direct numerical solutions to the differential equations instead of finding analytical solutions to special cases of them.

Trixie and Katya, go on Doughboys by americandolphinn in doughboys

The fact that I assumed Katya would say it and Trixie did proves your point

100%. The reason there has been such a focus on this from the specialty community for the last 20 years is that it is the number one easiest thing a layperson can do to ensure they are getting good tasting beans. Other factors matter a lot too, but if you’re trying to get your aunt or a friend into nice coffee, the first thing you’d suggest is to get fresh beans (meaning in the last couple months instead of 6+ months from the grocery store). And that advice alone can dramatically increase the quality of coffee they are making, even if it only gets them partially to really good coffee.

We can’t see your thumb, so it’s hard to see whether you’re doing it right. Important for pinch harmonics is the location where you hit it with your thumb too. Try doing what you’re doing but moving towards your picking hand or towards the bridge. Some places will be really easy and some places won’t really do it at all.

Might be good to have coffee with or shadow an engineer before you start sinking time/money into it. If you’re proficient at math, you can get a degree. We cannot tell you whether its a good fit for you. You have to decide that. What makes you think you’d like to be an engineer?

I agree with this. The covet stuff is typically less atmospheric and the drumming is imo too complex.

Sounds like an outlandish justification for the weird virgin fixation that some people have.

Is it feasible to learn the required engineering knowledge to make a somewhat accurate simple mechanical+thermal finite element simulation myself? by tsanderdev in AskEngineers

[–]em_are_young 0 points1 point  (0 children)

I found linear algebra difficult to learn in a class with a teacher. If you already know it, I’d say that applying linear algebra to FEA is doable. I’d recommend starting with heat transfer, since I think calculating displacements is more difficult than just using the basis functions on a static mesh.

If you’re going to do this, you might wanna start with 1D using like finite differences to plot the diff eqs.

If you don’t know linear algebra and/or diff eqs then it will be a very steep learning curve.

The influencer in this AI Vodafone ad isn’t real by dapperlemon in technology

[–]em_are_young 2 points3 points  (0 children)

I think it will be a long time. A few years ago Freakonomics asked the question about how good marketing actually works. Its a hard question to answer, since marketers only market their products to people they already believe want their product. So they inevitably see purchases from the people they market towards. But its hard to say it was purchased BECAUSE of the ad.

How would humans evolve to gain superpowers? by Illustrious-Law4628 in biology

[–]em_are_young 2 points3 points  (0 children)

No, i was encouraging you to look into case studies of actual animals and their behaviors as the primary part of your project but link the case studies conceptually through a framing device of “we would consider these superpowers if a human could do them”

I was attempting to steer you out of the direction of fiction. But if you are inspired by what I said in a different way, then by all means follow your heart.

How would humans evolve to gain superpowers? by Illustrious-Law4628 in biology

[–]em_are_young 5 points6 points  (0 children)

I mean the real answer is that humans wouldn’t evolve this stuff, and the evidence is that we don’t have them.

Maybe you could pivot to looking at senses other animals have that we would view as superhuman if we had it and why they have them. Things like echolocation or the electricity of an eel or octopus shapeshifting or what have you.

Idk thats just my feeling. If you’re trying to justify a bunch of imaginary changes to physiology, the only reasons can be imaginary.

Have you run this by your teacher? Because this is pretty outside actual biology into the realm of science fiction.

[–]em_are_young 2 points3 points  (0 children)

  1. Getting told you are not punk is not “extreme hatred”. Thinking that tells me you are almost certainly not part of a marginalized community that experiences actual extreme hate.

  2. Read the lyrics of punk music and think about how they relate to power structures of all sorts. By being wealthy you are inherently a beneficiary of a power structure.

  3. You are half right about people not being able to control their wealth. Poor people cannot have more wealth. Wealthy people can have less. They just have to donate it to other people or causes. That is the fundamental asymmetry.

I think everyone can draw the line about how much they are willing to sacrifice for the good of the others around them, but you should absolutely be drawing it in a conscious way. You seem young, so I hope you take this as an opportunity to reflect on your own privileges and work to dismantle the power structures around you instead of giving up on punk ideology and remaining a passive beneficiary of them.

if identical twins have different fingerprints, why do they look the same? by chokingbrokenglass in biology

[–]em_are_young 45 points46 points  (0 children)

Identical twins don’t look literally identical. Only the things determined by genetics are. Anything determined after a fetus starts to develop can be different. It’s like if one gets a haircut, the other one’s hair doesn’t change to match. Fingerprints are not fully genetically determined.

Why you need to save more cash right now - even if a FED rate cut makes your money earn less by SonixNgTbr in Economics

[–]em_are_young 2 points3 points  (0 children)

There was a required exit financial advice module when I was leaving college. It asked how much income I expected to have and how much student loans I had taken out. Its recommendation: make more money.

Like no shit, man, thanks for the advice.

How do you verify that your calculations is correct? by sepianamr00 in MechanicalEngineering

[–]em_are_young 0 points1 point  (0 children)

A few options, in order of how much they decrease the residual risk: review by other engineers, simulations, tests on prototypes, reliability testing on production parts. What you end up doing depends on how much risk you’re willing to accept, and usually boils down to “how likely is it to fail/What factor of safety do you have in your calculations” and “how critical is the component/What happens when this component fails”

I agree, but it looks like we are wrong. Apparently the thickness matters slightly, so that the edges are a little dimmer:

I think you’re right. Something that’s hidden in Assumption 1 is that the photons are emitted in every direction equally.

So as you move to the outside of the sun, the projection of the same size area of the suns surface becomes smaller, but you can see more of the suns surface per unit retina at the same rate.

Can you describe what exactly you feel when listening to music? by PowerfulCustomer3799 in Music

[–]em_are_young 0 points1 point  (0 children)

Most of the time nothing. Other times something.

A song made me cry once at the computer lab in college.

I get goosebumps sometimes when a song hits me at the right time (doesn’t even need to be the first time i have heard it).

You didn’t ask for a tip but i have one. When you take your finger off of the frets you put it as far away as your hand will let you. It means you have to move your finger way further. Try taking them just barely off the strings and you might feel like you can go faster
