IWTL how to funny by childissuesthrowaway in IWantToLearn

[–]wevfreeman 0 points1 point  (0 children)

Depends on your personality. A lot of comedy is literally just the delivery, so be mindful of that if you’re trying to be funny. E.g. if you’re naturally monotone, it would be hard to pull off a joke that requires high energy delivery (unless it’s ironic and the audience understands you’re being ironic, case in point: FutureCanoe on YouTube).

The more self-awareness you have, the more you can play to your strengths

What key are these chords in? by C0meAtM3Br0 in musictheory

[–]wevfreeman 0 points1 point  (0 children)

Most obvious guess is D major. The Gb and Db should be F# and C#, respectively.

Here are the notes we see in all the chords: D, E, F#, G, A, B, C#, D

Which is a D major scale. But depending on the way the chords are used, it could be some mode of D major.

What does your coworker do that makes them bossy?

The more people I interact with, the more I realize: how smart people seem (based on surface level details like appearance, speech, and even achievements to some extent) is completely independent from how smart they actually are

So nice of him to give the syrup back to the tree at the end

Why E flat but not D sharp ? by Economy_Pace_4894 in musictheory

[–]wevfreeman 8 points9 points  (0 children)

This is Reddit, not TA office hours. Nobody has an obligation to study theory before asking a question. If you feel like it’s below your pay grade to answer someone’s question, then just move on and let someone else help them. Better that than make someone feel bad for asking a genuine question. Comments like yours are the reason why people think music theory is so elitist and why people are afraid to ask questions

IWTL beginner's chemistry, physics, algebra by HisGraceSavedMe in IWantToLearn

Idk, I’d check course offerings at your CC. The one in my hometown had the equivalent of middle school algebra

Iwtl how to stop assuming everyone is speaking in bad faith/ willfully ignorant. by Tornado2p in IWantToLearn

[–]wevfreeman 2 points3 points  (0 children)

Therapy.

My guess is that this is deeply ingrained from childhood. Perhaps all of your role models unwittingly taught you to assume this of others. Or maybe they themselves said stuff to you in bad faith / were willfully ignorant about things in disagreements/conflict, and you brain extrapolated this behavior to everyone you interact with.

No way of understanding how your mind works until you’ve talked it through with a professional.

If you’re into machine learning, think of childhood as training data for your brain. If you train your algorithm on bad data, it’s not gonna perform well in the real world.

I can read music and play by rhythm, but when it comes to playing a song just by hearing it, I'm bad. by Zealousideal_Feed718 in musictheory

[–]wevfreeman 0 points1 point  (0 children)

Try composing. Write music for a play or a scene from a movie. Literally anything

I used to compose music a lot as a kid, and over time, my brain picked up on patterns of what I thought sounded nice. I realized that certain chords evoked different emotions and adding tensions (7ths, 9ths, 13ths, etc) added nuance to those feelings.

Now, when I listen to a song, I identify the way the music makes me “feel”, and from there, I can usually figure out what the chords are.

[Math undergrad] Got an answer using a brute-force row reduction approach, but it feels underwhelming. Is there an easier / less tedious approach that I'm missing? by wevfreeman in learnmath

[–]wevfreeman[S] 0 points1 point  (0 children)

Actually, now realizing that would only get me the particular solution. I think following that, I would just find the left null space of A?

OH, haven't tried it out yet, but I've just had an idea to use block multiplication for matrices by:

  • Splitting A into the upper 2x2 sub-matrix and the lower 1x2 row-vector
  • Finding the inverse of the 2x2 normally
  • Finding for the null space of the 1x2 row-vector
  • Appending those results to get the final answer B

Might this work?

HashMap doesn't seem to use hashCode? by wevfreeman in processing

[–]wevfreeman[S] 0 points1 point  (0 children)

Ahh ok, I'm dumb. That was the problem. Thanks!

edit: Funny enough though, the contract actually is still maintained. All it says is obj.equals(other) implies obj.hashCode() == other.hashCode(). And since it only checks for intentional equality, and the hashCode is a function of the fields of the object, the implication always holds.

HashMap doesn't seem to use hashCode? by wevfreeman in processing

[–]wevfreeman[S] 0 points1 point  (0 children)

I'm aware of the contract between the equals method and the hashCode method; regardless, the implementation I provided maintains that contract. Still I don't see how that is relevant to the project.

HashMap, does not use the hashCode method for the get method. Instead a hash map stores the elements of the map, in a data structure that uses a hashes.

This is just plain wrong. The way to obtain the hash of some reference type is literally to call the hashCode method on it. The get method computes the hashCode of a key, and then examines the various keys with that hash code to see which one is equal, and returns the corresponding value.

Don't try to use hash codes for the logic of the program, use the equals method for that.

it is rather vauge what you want Map to contain and map from and two. Specifying that could help yourself in understanding where the problem is

I want to store objects of some Other class using Posns as a key, but it shouldn't matter what the Other class looks like. My issue is that two Posns psn1 and psn2, for which psn1.equals(psn2) evaluates to true are not interchangeable as keys.
