Violin for me! Been going at it for a bit more than 3 years and have just started learning one of the Bach Sonatas.

It feels great to have a direct output from effort put in. The combination of physical and concentrated mental effort leaves me feeling refreshed after a good practice.

Low-plastic living. I read a book by the world's first zero-waste restaurant, Silo. The book got me thinking about how different our lives would be if oil were expensive. "Pretend oil is really expensive" is a good proxy for doing things that are "eco-friendly." Since reading the book, I've tried to eliminate single-use plastic from most of my life. It's incredibly hard. Everything from my socks to my vegetable packa…

If oil were expensive, plastic would probably still be used in all the places it is used today because it is lighter and a large percentage of oil goes into the transportation of goods.

I actually don't have a problem with plastic, at least in theory. Oil exists in the ground. I don't see an issue with pumping it up, using it for a bit, and putting it back into the ground via a landfill. I take more of an issue with recycling where plastic is shipped overseas and makes its way into the waterways.

Studying the relation between just how volatile SPY 0-day-to-expiration options are in regards to the underlying. A 1% directional move in SPY can yield a 1600%+ in most cases if you can time it right in regards to direction + strike.

I would never actually trade or anything like that. It's just fun to scrape data. Historical option chain data isn't really publicly free/available so I wrote a scraper + analytics on top of it.

Moving golf simulation into the cloud [0]. Golf is one of the only sports that can be realistically simulated indoors. Golf is also one of the only sports where even severe lag has no effect on the accuracy of the play - just the viewing experience. Unlike FPS games in the cloud which become unplayable with even modest lag. The golf simulation technology landscape today is pre-cloud. People running their own gaming c…

your site flashes and loads content for like 10 seconds for me. the content just keeps moving up and down...

Is it possible you have first party cookies disabled? On your first visit we need to run some JS (apparently the only way to get the user timezone). We store that in your session and then redirect you so we can show availability in your timezone. If first party cookies are disabled then there will be no session and the page will loop. (Open to suggestions on better TZ handling - other than rewriting as an SPA :)

Learning Korean to better communicate with my GFs family and take advantage of _finally_ having real motivation to learn another language. I'm really enjoying having a different type of challenge than I'm used to. Mostly approaching it with Duolingo and Anki vocab cards with moderate success so far. We both have our own careers, kids, various responsibilities...so I don't get much time to practice with her. And pract…

Practice in the morning

There is a new show on HBO called Scavengers Reign, and it's become my favorite scifi story ever. https://www.imdb.com/title/tt21056886/ It's kinda like watching Planet Earth about another ecosystem, with a strong focus on judgment-free ecology (ie there isn't good and evil, just different flora and fauna and otherwise interacting both with their normal food webs and with human outsiders). It really tickles the envir…

Haha, yea I binged that one too. I'd give it a similar description, I loved it. I also watched Pantheon. There are a few questions in Pantheon that are interesting to imagine. Also, the computer science fan service (like the philosopher's problem in concurrency/multithreading) feels fun - irrelevant to be honest, but fun.

Getting Ohio House Bill 14 passed and fathers rights in general.

Right now in the state of Ohio a father has 0 default rights to his own children, even AFTER paternity. Ohio is a "mothers rights" state meaning that be default the mother has 100% custody so it is always an uphill batter to get time with your kids if the mother doesnt want you to.

This post caught my attention because recently I met a woman I really admire. She dropped out of her computer engineering class, took a vow of celibacy and poverty and became a missionary with a Catholic sect. The reason I admire her isn't that. What caught my attention about her is that she has a sense of purpose. She has a purpose in life and has devoted her life to it. I used to have one. My goal was to make the l…

Thanks for your honest answer. Finding purpose is a pretty good passion

The following open research problem. Given an undirected graph G with two vertices s and t, the task is to determine whether there is an undirected path connecting s and t which is simple (no repeated vertices) and has length divisible by 3. It is not known whether this problem is NP-hard, or whether it can be solved in polynomial time; apparently the question is open since the early 90s. (The problem is also open fo…

What makes it NP-hard? Naively, I would assume the number of simple paths between any two nodes in a graph to a polynomial function of the number of nodes plus the number of edges, so checking every path wouldn't be hard.

Earlier quoted context omitted.

I just began the 5/3/1 strength training method. I’d like to use gymnastic rings for most of my accessory work to try and get a nice balance of strength and flexibility.

I tried 5/3/1 in college and I after week 4, I felt like you need to be juicing to keep up with it.

No.
