Biology on Khan Academy. We're making plant-based cheese and are experimenting with enzymes to make better and new varieties of cheese. We already have one Ricotta-style cheese (fresh cheeses you often make with acids, so that works well with soy protein, too). Our hypothesis is that there must be enzymes that works similarly with plant proteins as chymosin (part of rennet used in cheese making) works with casein. So…

this sounds really interesting. i am personally very passionate about this space (reducing the impacts of factory farming due to unethical treatment of animals), but as a systems engineer (with degree in mechanical/electrical/software) i don’t really have the Bio background to get more involved. did you find that to be a hindrance for yourself?

Thanks, yes it an important topic that's still underrated today I think.

I wouldn't say hindrance, but it would probably be a bit easier if I had a biochemistry or food engineering/science background.

My partner has an environmental science background, so that helps a bit and she is the one doing most of the experimenting.

But in the end, it's about trial and error. That's also what an expert would need to do. I think if you're interested enough in the topic it's possible to acquire the necessary knowledge.

We plan to hire experts later on once we have the cash to do so (we're not raising money, all bootstrapped).

Managing outsourced content writers.

I’m building up the side hustle gradually to escape the soul-sucking grind of the day job, and being a good manager of an outsourced team will allow me to take things to the next level.

Brazilian Jiu Jitsu aka BJJ. Physical problem solving under pressure.

I started training kickboxing now, after 2 years of mma and 1 year break of physical activity. Martial Arts are the best!

I agree. I learn Muay-Thai (Thai boxing), and this is incredibly useful, mainly because I have to (try to) switch from my usual "thinking for hours/days/months to a problem" mode into "flowing, neglecting analysis/systemics/... and letting whatever is left take control and act/react RIGHT NOW".

Complexity Economics I've been binging books on the topic as well as exchanging dialogs with a colleague over email. Books list: _Completed_ The Origin of Wealth: The Radical Remaking of Economics and What it Means for Business and Society - https://www.amazon.com/gp/product/1422121038/ref=ppx_yo_dt_b... Increasing Returns and Path Dependence in the Economy (Economics, Cognition, And Society) - https://www.amazon.com…

Great list, another one I would add is "The Misbehavior of Markets" by Benoit Mandelbrot:

Piano. I've decided that more programming languages or web stacks are a complete waste of time. Piano is for life and I wished I had started doing this in earnest long ago.

A fun tech-related project is hooking up an addressable LED strip to a digital piano and making the strip respond to your key presses - via a Raspberry Pi.

My repository for this (code finished, just need to add photos and add a write up about how to use):

https://github.com/whyboris/Digital-Piano-LED

I added a feature that the left and middle pedal buttons navigate through sheet music (PDF left/right button). And I'm also running Pianoteq which makes any (even dinky) digital piano sound like a $100k grand piano (or any piano you pick for that matter) https://www.modartt.com/pianoteq

Classical AI planning in Picat, which is like a mix of Prolog, Python and Haskell. Following this book here: http://picat-lang.org/picatbook2015.html

I think planning is extremely neglected and undervalued for what it is. The field is a mess, but there's real opportunity now with all the progress in reinforcement learning.

Learning Latin following this method: http://wcdrutgers.net/Latin.htm and also working on some mobile apps (iOS using SwiftUI, lot to learn but pretty pleasant experience) for personal use.

Edit: In the past I've tried to do too many things at once and ended up making only limited progress on any of them as a result, so I'm trying to focus on just 1 or 2 things at a time now.

To sleep on my back. Being a life-long side sleeper has caused a lot of shoulder and upper back problems that sometimes make it hard for me to reach out and type. I wish I'd done this ages ago. It's one of the hardest things I've had to learn.

I'd love to learn this but get sleep paralysis for 30-60 seconds at a time for like an hour (i have no way of knowing how long the intervals are but that's what it feels like) every time I do - has anyone overcome this?

Consult some doctors.

I'm sure many here on HN did this long ago, but for me: Learning how to get by in a large org for the first time. 1 month ago I was responsible for the entire IT function of an SMB. I was the guy who knew everything required to get stuff done, and I reported directly to the CEO. A lot of processes were not formalised because the overheads of doing so weren't worth it. New job, now working for the government in a skys…

A couple of things I've learned over time: - Soft skills matter, but performance (against your metrics) is still what matters in the end. Group dynamics only comes into it when you have a bunch of people at the same level of performance. - You'll be ahead of a lot of your peers if you stay positive and don't gossip and don't do office "politicking" (in a bad sense). - Plan your career around three year stints. At the…

This is important. I've worked with people who are constantly criticizing the company/other people, and while they are usually right, it undermines the morale of everyone else.
