Notes on The Innovator’s Dilemma: When New Technologies Cause Great Firms to Fail

• Book by: Clayton M. Christensen, Cambridge, Massachusetts: Harvard Business School Press, 1997
• Prepared by: B.B. McBreen. See [PDF][1] (more readable but it's not plain text)

Summary

1. Market progress is separate from technology progress. Customers do not always know what they need.
2. Innovation requires resource allocation which is extraordinarily difficult for disruptive technologies.
3. Disruptive technology needs a new market. Old customers are less relevant. Disruptive technology is a marketing problem, not a technological one.

Synopsis

At the top of the file there should be a short introduction and/ or overview that explains what the project is. This description should match descriptions added for package managers (Gemspec, package.json, etc.)

Code Example

Show what the library does as concisely as possible, developers should be able to figure out how your project solves their problem by looking at the code example. Make sure the API you are showing off is obvious, and that your code is short and concise.

Every time I upgrade libxml2 via Homebrew, running cucumber test will post an annoying warning message

WARNING: Nokogiri was built against LibXML version 2.7.3, but has dynamically loaded 2.8.0

To fix it:

$ gem uninstall nokogiri
$ brew link libxml2

$ gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.8.0/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.8.0/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

I have now hit my first "wow" moment with Rails, where I actually understood why it has the following it does. It has raised some questions for me about the pedagogy of Rails, but that is not the language's fault; it is a question for the community.

Rails is fast. Mind-blowingly fast. From my cursory looks at the framework, it is immediately apparent that this was designed from the ground up to give me everything I'm going to inevitably want in a basic web application. And yet, for some reason, it isn't immediately sold that way. It's instead sold with stuff like...

"I'm not even joking when I say this, but I think some of the resources out there make it intentionally hard for non-technical people to start learning."

The above line was from a class on Rails - not a Ruby class, but a Rails class. The class was designed so that you could have no coding experience whatsoever and build an MVP, and it advertises itself as such. I think learning to code, even at the lowest level of difficulty, is a fantast
