Re: Ask HN: What are you learning?
#322Right now, I'm learning math. I met a PhD via Discord who is giving me problems to work and checking my solutions. It's been quite fun so far, working on Real Analysis and Abstract Algebra. I'm also doing baking; baked my first loaf of bread yesterday. Really interested to learn (and eat!) more. I'm tempted to pick up a cheap instrument and learn one as well, or delve back into Python some more. Or drawing. My main i…
I'm curious, how could someone find a PhD/researcher on Discord, esp. for this kind of purpose?
I found them on /r/math, actually, but they linked me to Discord.

#324I’m taking weekends and evening off so I don’t burn out.
I’m working on learning a piano piece by a composer named Kapustin.
If you haven’t listen to him I highly suggest him.
Since I got my degree in piano performance, I’ve not learned any big pieces and I’m excited that I’m finally doing it.

#325Earlier quoted context omitted.
I was indeed trying to avoid the big libraries, since this is just for personal use I don't care about cross platform which allows me to escape these potentially - I may well end up back at the SDL + OpenGL level later when features or performance are a concern. My current goal is to find a balance of least dependencies and least boilerplate to draw a pixel buffer so i can play with C, nothing more. Once I can do tha…
Then you should be using X11 directly!
My goal is to attain a balance of least dependencies and boilerplate. From what I've read so far it seems that implementing xclient protocols directly would require considerably more boilerplate than using XCB, (and my understanding is that XCB is just that: a generic xclient implementation and nothing more).
Please do elaborate if I'm wrong though! I would be delighted if it's possible to implement a simple subset minimally purely for displaying a pixel buffer without XCB?

#326Marxism In Our Time, an article by Leon Trotsky. A summary of Marx's theory of capitalism, specifically as it pertained to the great depression in the United States, when incredibly high profits and a surging stock market were accompanied by massive inequality and then it all crashed, causing widespread poverty and social unrest despite society's technical and material ability to provide for everyone. I think it will be very relevant soon.

#327Russian, Rust, and Domain-Driven Design. Lots to go! Lots of depth to these three rabbit holes, and only two have some overlap.

#328vue.js for a potential upcoming job requirement. Seems easy enough, but not sure I'd want to use it personally.

#329The business side: How do you find your customers, position a product, and create demand. What about new markets, segmentation, downstream and upstream?
Bad technology that gets this part right almost always does phenomenally, astoundingly, inconceivably better than great technology that gets it wrong.
I'm tired of building things that only I and a few people really like, like some underground band only a few people know. It's nonsense, I gotta learn how to do the human part better.

#330I'm working through Aluffi's Algebra: Chapter Zero , which covers abstract algebra (groups, fields, vector spaces, etc.) with category theoretic foundations. I took undergraduate algebra several years ago, and I'm really interested in category theory from a compositionality perspective, so this is a good opportunity to brush up on both topics. Aluffi is really well-written. It assumes some degree of mathematical matu…
This really reminds me, it's been two decades now since I've taken _any_ Algebra. I'd really love to go re-learn it from the basics on up. I mean, I still remember a lot of it here and there but some sort of refresher course up to doing more advanced would be awesome. Any recommendations?
Hell yes! I love hearing about people interested in abstract algebra and wholly support your endeavor! Here is a pretty decent resource on relevant texts:
http://www.cargalmathbooks.com/#Abstract%20Algebra
That page in general is pretty gold for math texts in general.
Also, #math on freenode has lots of algebra-strong users on it, though depending on your luck some can be less helpful than others. I love chatting about this kind of thing with people, so if you would like an ad hoc mentor/study-buddy I would be more than happy to help. Feel free to email me at the address in my profile.
Good luck!
