Go (Golang) Standard Library Interfaces (Selected)

This is not an exhaustive list of all interfaces in Go's standard library. I only list those I think are important. Interfaces defined in frequently used packages (like io, fmt) are included. Interfaces that have significant importance are also included.

All of the following information is based on go version go1.8.3 darwin/amd64.

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

The Rules of React

All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.

What Functions Are "Pure"?

A number of methods in React are assumed to be "pure".

On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

There's a lot of recommended reading for product managers out there. Some of it is incredibly useful, and some of it is a waste of time. Business books don't really get me excited, but there are a few books, articles, newsletters, and podcasts authored by folks I look up to in the industry that I find myself coming back to often. When you're reading about product management, it's important to take everything with a grain of salt. The industry changes rapidly, and so does the discipline. If you learn something you want to try out from one of these books, go for it! But be careful not to whiplash yourself or your team.

I find new books and articles all the time, so I'm going to start dropping them here. Hope they help and inspire some other Product folks!

Product managers

• Seek out failure, it teaches us to think like a scientist. If you start with a hypothesis, then try to prove yourself wrong, you’re bound to make much better decisions. You have to be willing to fail, and that in itself is going to help you build confidence and be more convicted about what your strategy is in the end.
• There are hundreds of methods for building products and running teams. As a quality PM, it's important to have an open mind about all of it, but finding your own process and philosophy can be grounding. It helps you find your pillars so that you don't smash into things while you're building. Remember, however, that you can always find a budget for remodeling. 😉
• The beauty of a good process is when it just becomes how you do your work. When you forget you're following a process at all is when you know the process is working for you, your team, your company, and your customers.
