There’s a lot of advice on product floating around out there.But something I don’t see enough (and what I wish I learned earlier) is to start developing a personal philosophy on product - both what makes good product and how to build it.— Avneesh Kohli (@avneeshk91) September 23, 2018

reasoning about the system should be done recursively on its structure. ​ good software design is ultimately an art. ​ another example of reasoning via an interface. ​ I suspect that interfaces are in fact synonymous with compositionality. That is, compositionality is not just the ability to compose objects, but the ability to work with an object after intentionally forgetting how it was built. ​ can interact in complex ways that block understanding ​ More generally, I claim that the opposite of compositionality is emergent effects. The common definition of emergence is a system being ‘more than the sum of its parts’, and so it is easy to see that such a system cannot be understood only in terms of its parts, i.e. it is not compositional. Moreover I claim that non-compositionality is a barrier to scientific understanding, because it breaks the reductionist methodology of always dividing a system into smaller components and translating explanations into lower levels.

“One way of looking at the difference between progressive and consistent habits is that the former are about managing growth, while the latter are about managing decline.”

Every September since Apple released the Apple Watch, we’ve seen a brand new version of watchOS come out that improves the experience. Here’s a brief recap: * watchOS 1 (Apr 2015): way more functionality than needed, and super slow * watchOS 2 (Sep 2015): slightly faster, and better APIs for

“They’re winning, but they don’t just want to win the race. They want to win the race while driving the best-looking car on the track.”

“We have a vague idea in our head of the “price” of certain accomplishments, how difficult it should be to get a degree, or succeed at a job, or stay in shape, or raise a kid, or build a house. And that vague idea is almost always catastrophically wrong. Accomplishing worthwhile things isn’t just a little harder than people think; it’s 10 or 20 times harder.” “But the switch towards taking on a practice and discipline is admitting to yourself that you suck and you want to get better.”

Whenever someone says, “You should do a parenting book!” I think of this tweet.

Light-skin-tone symbols are used far less often in the U.S. than their darker counterparts. Does shame explain the disparity?

In June 2015, the Unicode Consortium blessed us with a handful of new emoji including a burrito 🌯  and a cheese wedge 🧀. Perhaps the most think-piecey new addition to Unicode 8.0  was the inclusion of various skin-tone options for the hand-gesture and people emoji, which sparked

“An athlete without a coach is incomplete. So, why don’t we think the same way about coaches for CEOs?” “Matt’s coaching methodology is to act as a shadow CEO one day a week, including sitting in on all the one-on-one meets with the senior team and on the leadership meeting. Matt’s initial focus was on improving my personal productivity with a set of tools like GTD and a series of audits of my time and processes.. Once I was convinced of the benefit, he moved his focus to my senior team and the rest of the organization.”

Growth hacks everywhere — and it’s about to get even worse

I’m proofing the third pass of Keep Going. I find it really difficult at this stage of a project to get the right perspective — “fresh eyes” — for the thing, which makes it really, really hard to make edits. The production schedule for this book has been much more accelerated than any of my
