Saw this post on mathematicians disagreeing on 0^0. It was a little bit interesting, but then this Hacker News comment by Kalid was exceptional. The relevant part -
How would you explain to a 10-year old why 3^0 = 1 beyond "it's necessary to make the algebra of powers work out". I use an "expand-o-tron" analogy to wrap my head around what exponents are really doing: some amount of growth (base) for some amount of time (power). This gives you a "multiplier effect". So, 3^0 means "3x growth for 0 seconds" which, being 0 seconds, changes nothing -- the multiplier is 1. "0x growth for 0 seconds" is also 1, since it was never applied. "0x growth for .00001 seconds" is 0, since a miniscule amount of obliteration still obliterates you.
It was a fascinating discussion, but I'm most interested in the bolded part which says it perfectly - "a minuscule amount of obliteration still obliterates you."
This is very important in business, especially if you're doing online type stuff where many of the probabilities are invisible to you unless you carefully study the analytics. Analytics-inclined people already do this, but in 2011 that's still definitely a minority of the business population.

Question from a reader -
You strongly recommend audio books but I have a bit of trouble seeing myself listening to them regularly.
It just seems vastly inefficient compared to books, and even though it has the same content (perhaps even more through intonation), I feel as though I lose a lot of context when I listen to or watch things instead of reading them - perhaps a different part of the brain is being used? I think the exception to this is motivational work such as Brian Tracy (who I dismissed without reason as some sort of get-rich-quick schemer but gave a listen after your recommendation and enjoyed). Actually, I think conversational style books such as Gladwell's tone, or the research-heavy but not-too-deep books might work well as audio so I may have answered my own question.
Anyway, how did you make the jump to more audio books? What great books switched you over? Why are you such an audio book fan (all the extra books is a good argument, but I feel like there's a lost cost of all the books I now won't read and would hate to risk the greatness of a good book, just as one should usually read the novel before watching the movie).
Okay, this is a common question, observation, and mistake I see. You're thinking "audiobook = replacement for book"... but it's not. Audiobooks are a replacement for staring at your shoes while you're waiting to clear customs and immigration at the airport, while you're in line at the grocery store, or while you're going for a walk or otherwise running errands.
Was exploring this in my own notes. Here's what I came up with -
The writing skill is the act of:
*Sitting down somewhere suitable to work *Outling a rough idea of what I want to write *Starting to write (by which, I mean starting to type)
But sometimes I "don't have it" - then what?
Well, alternatively I can: *Write ANYTHING *Read a little while *Just sit there and suffer
Was up late last night, woke today 11:30AM.
Man, the difference between waking at 4:30 and 11:30 is staggering. If I had to guess, I think I'd guess somewhere between 300% and 500% higher productivity for being up at 4:30AM.
If you do "standard morning stuff" after waking for 30-60 minutes, shower, groom yourself, and eat, you can sit down to work sometime between 5AM to 7AM on the early schedule.
You're starting between noon and 2PM on the late schedule.
Why's it matter? A lot of things. Psychologically, the "ahh, I'm up early" helps. Then, it seems like we naturally start to slow down when it starts getting darker at nights.
From a recent Hacker News comment by me that was both popular and controversial, in response to the declining fertility levels, declining interest in family, and projected downturn in Asia -
I have a theory that I haven't found expounded before. It came from a combination of travel through 60+ countries, living and working and interacting with local people on a pretty intimate level sometimes, and study of lots of history.
It's going to be controversial and maybe even shocking, so brace yourself for a moment before reacting please.
I think peaceful societies self-destruct.
With a few notable exceptions that require a geography suitable to isolationism, long term peace has historically been achieved through your country or one of your ally's having military supremacy over the rest of your neighbors.
Very good question by a regular reader of the site who just joined a new company. Some excerpts -
Do you have any sources to recommend regarding the topic of Small-scale Team or Project Management? The background on my request is simply that I work for a large, very disorganized company that grew from a small "mom & pop" to a competitive industry leader in a 'short' time period (10 years or so). The management has not followed the change with the kind of organizational structure that large companies require for effeciency and they abhore 1) change 2) young people initiating change 3) publish initiatives for change with deadlines, and blame the 'young people' when they aren't completed, meanwhile they sabotage all efforts to work on them.
Now, I am no expert on creating the type of organizational structure we need here, but I witness its absence as a massive failure each and every day in my own department and all of the others as well. My team consists of 3 members, 2 analysists and 1 "manager". Our manager is inept. We have had projects for the last 4 years (prior to my hire) outstanding, which if successful could have significant positive impact on finacials, performance, effeciency, communication... I could go on. Our manager belives that such projects are superfuluois and openly harasses us when we work on them (despite the wild success of the first one...which he attributed not to hard work but to "magic"- literally, he said it must have been magic and denied any part we had in achieving the goal).
It's my birthday today.
I didn't really notice until yesterday that it was coming up on me. Today I slept in a little, discussed real estate in the morning, worked some, and am now in a cafe doing odds and ends with a coffee and some good bread and pastries (it's cheat day on my diet).
Tonight, I might have dinner with a friend or might not, and today is otherwise a normal day like tomorrow.
It seems like a lot of the time, I mention this to someone and they say "oh, that's so sad! why don't you have a celebration?"
And I never had a good answer to that. Now, I think I do.
A couple days ago, I told a Nigerian engineer to "Work online. Use freelancing sites. Lie about the country you’re in. [...] There’s a big stigma against Nigeria. That’s just reality, and you need to deal with it."
A reader replies -
I feel for this guy but I am surprised you recommend lying. There has to be another way. ... I have a problem with lying, period, and perhaps I’ve misunderstood Sebastian but I think he stands for straightforwardness.
Let's talk about this straightforwardly, like adults, like grown-ups.
Most people won't do that. It's inherently weird. Most people don't own up to the fact that they lie, yet almost everyone does so. A lot, actually.
More Dalio. Man, this small book is so dense with good stuff. Bold added by me -
199a) Don’t be a perfectionist, because perfectionists often spend too much time on little differences at the margins at the expense of other big, important things. Be an effective imperfectionist. Solutions that broadly work well (e.g., how people should contact each other in the event of crises) are generally better than highly specialized solutions (e.g., how each person should contact each other in the event of every conceivable crisis), especially in the early stages of a plan. There generally isn't much gained by lots of detail relative to a good broad solution. Complicated procedures are tough to remember, and it takes a lot of time to make such detailed plans (so they might not even be ready when needed).
199c) Watch out for “detail anxiety,” i.e., worrying inappropriately about unimportant, small things.
Very useful term - "detail anxiety." Useful to think about - and strive to avoid.
Got an email from a Nigerian engineer asking for my take on where he's at. Basically, he's on a steady upward career track but he doesn't care for his field of engineering. So he's got a tough decision at hand - he's already got a great credential and skills, but he really wants to do more abstract/entrepreneurial work - but he doesn't currently have the skillset for it. He had two kinds of questions - a high level strategic question about whether the tradeoffs between switching professions are worth it, because he'd be losing out on a lot of his current credentials/skills and be behind other people. And second, tactical questions on getting started on the creative/entrepreneurial path even though he's got a good full-time job right now that he doesn't love, but doesn't want to quit.
He felt pretty unhappy and stuck when he wrote - good solid job right now, not a ton of other opportunity in his area, and worried about how his skills and life would transfer to his desired field. Here's my reply -
Okay. You're obviously a highly intelligent guy. I think one problem that people have is when they decide to become ambitious, they see there's 10,000 ways they could improve and it's easy to kind of panic or get overwhelmed.
Don't panic. Don't get overwhelmed. Calm down, pick 1-3 things to work on, improve those areas like crazy, then pick the next ones. Rome wasn't built in a day.
