Actually sitting down and understanding what it's about, trying it out and implementing it should be possible within 1 hour without ever having touched it before, and has at least a huge potential to make you way better at Git.

#672On the contrary, it has taken me years to unlearn compound interest. When you start with relatively little, compound interest is relatively very unhelpful - it compounds wealth and benefits people who have started with something more than you. Twice as good at nothing is still nothing.
Sadly, a huge number of people can't do that. If your bills are $1000/mo and you earn $1001/mo, and invest the entire excess, when you're old, you'll have below $8 for every month invested today, which is meaningless compared to your expenses. 8 times nothing is nothing. But if your bills are $1000/mo and you earn $1130/mo and invest the entire excess, it'll entirely pay for a corresponding lifestyle when you're old.
Perhaps a more important lesson in that case is compound interest on debt. If you borrow money from a credit card company, you can get exponentially fucked. The lesson may not be that compound interest gets you wealthy, but it's certainly that compound interest can make you worse than broke.

As much as I dislike seemingly knee-jerk contrary statements against “known-good” knowledge, I feel that there is an important point here: aggressively attempting to compound interest is a poor use of time when you only have, say, hundreds of dollars. Better to focus on compound interest “in the background” while optimizing for growing capital or income-generating skills.
So, essentially: compound interest is something wealthy people are good at because it's useful when you are wealthy. Not because learning about compund interest will make you rich?

#674Those are both examples of "automated build tools". If you do data science, and have even a moderately complex graph of dependencies (i.e. some files need to be built before others can be built), such a tool is an absolute lifesaver.

#675Maybe the basics of "How to Win Friends and Influence People." https://fs.blog/2012/07/how-to-win-friends-and-influence-peo... Then applying it will take longer though.
Real friends don't let friends read "HtWFaIP".
"The secret of success is sincerity. Once you can fake that you've got it made." - Hippolyte Jean Giraudoux
Don't be that person. Cultivating genuine sincerity is part of your own self-respect. If you genuinely do that, you can safely read HtWFaIP.

Haven't seen the videos, but I was taught the "proper" way of wrapping audio cables when I took an audio recording class, and now I obsessively wrap all my cables that way. So much more useful!
> So much more useful! The only cables I really deal with are network cables and extension cords and I've always just done the wrap-around-your-palm-and-elbow-method. What am I missing out on?
The person who showed me how to do it said, "If you've done it right, you should be able to do this"; and with the coiled microphone cable in one hand, she held one end with her thumb and tossed the rest of the coil outwards. It uncoiled in the air and landed in a straight line, no tangles or knots.
Basically, if you do this: 1) The cables are less likely to be damaged, 2) the cables are a lot more 'weildy': they don't get tangled in interminable knots, and expand very easily. The cables themselves remain looking nice as well, and don't get ugly kinks in them.

#677Do nothing. Seriously. Allow yourself to become bored and you'll find your brain has suddenly got time to work on all the problems you mentally shelved. There's a good reason why a good number of ideas happen in the shower.

There is this nice book called "The Slight Edge" which builds on this whole idea in general and how it is applicable at every facet of life. It is really an insightful book and atleast you will slightly change about how you think about stuffs.
I'm reading *Atomic Habits right now and the author talks about how building small improvements on top of each other can eventually deliver great gains. The trick seems to be identifying just what it is to work on.

#679How to cook for yourself, really, really good food. I no longer crave restaurant food, and all of the really important things I learned about cooking take just the time to read it, hear about it and then try it. All without any special hardware. A few examples: 1. Cooking jasmine rice: rinse it first, 1 c. water to 1 c. rice ratio. Bring to boil, turn down heat to lowest setting. Leave lid /the entire time/. Fluff th…
My partner really picked up cooking in the last couple of years. We hardly ever go out anymore. Every time we get a craving she says "Yeah, we could go to a crowded restaurant... or I could make it better". Without fail, she does. I think the secret is, one of the most important aspects of good food is time to table. When you make it at home, you can eat as soon as it's done or rested. Along with the anticipation fac…
